• What DNS server to use for dynamic load-balancing of website?

  - by Marki555

  I will have 2 servers in different datacenters (different countries) and I want to use DNS load-balancing mainly for High Availability of website hosted on those 2 servers. It is just ad tracking site, which records hit in local database and returns few lines on html code. I want to return 2 A records each time because of DNS pinning in browsers (if one server fails, browser will try second A record which it has already cached). Both servers will be acting also as DNS servers for redundancy. Now comes my proposed solution: I will use BIND and have both servers as a master for that zone. On each server there will be running script, which will periodically test availability (http) of both servers and remove IP from DNS in case of failure. Now the questions :) 1) Is BIND suitable for this solution? I think BIND performance is good and it is easy to manipulate the zone file via script. And as I will modify the zone only in case of failure/maintenance, the modifications (and thus bind reload) won't be often. 2) I plan to use TTL of 5 minutes. The website will have about 1000-3000 req/s but from distinct clients (each IP only 1-3 requests), so I think the DNS load won't be too much. I suppose their ISPs will cache the responses for those 5 mins. Is there any reason to lower the TTL even more? 3) Is my master-master approach good? Or should I make one of the servers master and the other one slave? Right now each server can monitor both itself and the other one. If only webservice fails, both DNS nodes will notice it. If the whole server fails, then the remaining DNS node will notice it and the failed node will not answer DNS queries anyway. 4) Is it a big issue when one NS server does not respond to queries? If yes, I can make a third DNS, so anytime at least 2 of them would accept queries... 5) Should I rewrite the zone file via script, or just use dynamic DNS update (for example via nsupdateutility)?

• Possible HDD malfunction. Need help in diagnosing

  - by Protheus

  Today when using my PC as I did for almost 4 years I experienced the following: during opening new tab in Opera browser screen froze. Music (AIMP 3) continued to play for about 5 minutes and then stopped too. I tried Ctrl+Alt+Del, but win7 lock screen didn't appear. Caps\Scroll or Num locks didn't switch diodes on keyboard. I rebooted my PC and saw that BIOS suggests me to enter it's settings or load by default. I chose default. It don't see proper boot device (old faitful "insert proper boot" something). After second reboot it said that there is no ExpressGate installed (which i turned off in BIOS years ago). I went into BIOS setting to turn off ExpressGate and see configs: time was not set off, all hard drives present, temp and O.C. settings are nominal (no O.C.) I've inserted my Win7 install disk to try recovery. It did load awfully long (about few minutes) and didn't see current installation. PC was utilized in 24/7 mode for almost all these years. Hardware configuration: ASUS P5Q WS Core 2 Quad Q9300 (2.5GHz no O.C.) MSI geForce GTX 460 4x2 Gb GeIL EVO 2 (AFAIR) Seagate something 750Gb (4 years as system HDD 24/7) WD 1Tb (for random stuff, 5 y.o.) Hitachi 500Gb (for even more random stuff, 6 y.o.) NEC DVDRW (ALL DISKS ARE SATA) Cooler Master Silent Pro 700W Software: Windows 7 AND Kubuntu on the same drive with GRUB loader. Sorry I can't remember HDDs and can't see them right now, but I think their models aren't relevant anyway. My idea is that due to some system error or hard drive glitch i've wrecked my primary HDD's MBR. Nevertheless I don't exclude the possibility of other failure. May it's be that motherboard or it's SATA controller? Doubt it, because all drives are seen in BIOS and I could load from DVD. Maybe GRUB got bugged somehow, although I don't see how it's possible from Windows. But I did install KUbuntu from Windows (i wasn't myself then), maybe GRUB did write itself in some windows partition and got rewriteen in process? Right now I am at work with my flash drive with me and I need some advice how to fix MBR or to hear if it's not MBR. I'm going to buy new HDD (Hitachi 7k2000) because I think that my current HDD is compromised and it's unsafe to use it as system drive, especially 24/7.

• Concerning persistence size in the Linux Live Creator

  - by user63085

  Message : Hello everyone! I have ,for the last several months, used the Linux Live USB Creator which it is a very useful app to make portable OS on to flash drives. I mostly use this application to test and try out new OS's as they are released, before I decide to make a hard disk installatio on to the computer. In many cases, the application developers will allow the “persistence” feature in the flash-drive-installed OS, which is just another way of saying that after multiple boot-ups and shutdowns, all the changes made to the OS will be saved in the flash-drive. But I have a question about the limit of the Persistence size in Linux Live USB Creator (currently version 2.6). I install Super OS 10 on to a partition on my external drive which has 30 GB. I wanted to reserve 10 GB for the persistence so that I can install more applications and space will not run out as I update the installed applications or when I do system updates. But why is it that only 3950 MB can be put for persistence? It would be great if, when desired, as much more persistence space could be set aside so that the space will not run out soon. Also, as I have installed the OS on a 30 GB drive, I tried to see how much space is left. But it seems only the remaining of the Persistence space is displayed when I click on the File System folder. For example, after I have just installed it now, there is 3.5 GB of free space. Where can I access the remaining 26 GB or so drive space which is in the same drive? How do I access it Sir?? It would be helpful if any one could explain and help me with this. Most importantly, it would be a big relief if the persistence can be somehow expanded by a work-around so that I can continue using my SuperOS 10.04 (now heavily customized) OS, which unfortunately has just over 576 MB of space left now, after I removed OpenOffice.org and installed the Libre Office earlier today. This is what remains from the maximum allowable 3950 MB of space for persistence at set-up. Thanks in advance!

• Troubleshooting Network Speeds -- The Age Old Inquiry

  - by John K

  I'm looking for help with what I'm sure is an age old question. I've found myself in a situation of yearning to understand network throughput more clearly, but I can't seem to find information that makes it "click" We have a few servers distributed geographically, running various versions of Windows. Assuming we always use one host (a desktop) as the source, when copying data from that host to other servers across the country, we see a high variance in speed. In some cases, we can copy data at 12MB/s consistently, in others, we're seeing 0.8 MB/s. It should be noted, after testing 8 destinations, we always seem to be at either 0.6-0.8MB/s or 11-12 MB/s. In the building we're primarily concerned with, we have an OC-3 connection to our ISP. I know there are a lot of variables at play, but I guess I was hoping the experts here could help answer a few basic questions to help bolster my understanding. 1.) For older machines, running Windows XP, server 2003, etc, with a 100Mbps Ethernet card and 72 ms typical latency, does 0.8 MB/s sound at all reasonable? Or do you think that slow enough to indicate a problem? 2.) The classic "mathematical fastest speed" of "throughput = TCP window / latency," is, in our case, calculated to 0.8 MB/s (64Kb / 72 ms). My understanding is that is an upper bounds; that you would never expect to reach (due to overhead) let alone surpass that speed. In some cases though, we're seeing speeds of 12.3 MB/s. There are Steelhead accelerators scattered around the network, could those account for such a higher transfer rate? 3.) It's been suggested that the use SMB vs. SMB2 could explain the differences in speed. Indeed, as expected, packet captures show both being used depending on the OS versions in play, as we would expect. I understand what determines SMB2 being used or not, but I'm curious to know what kind of performance gain you can expect with SMB2. My problem simply seems to be a lack of experience, and more importantly, perspective, in terms of what are and are not reasonable network speeds. Could anyone help impart come context/perspective?

• vmdk to live cd - VMware vmxnet virtual NIC driver Kernel panic

  - by ronalchn

  Task I am trying to convert a virtual machine to a live CD. Specifically, the virtual machine I am trying to convert is the IOI 2013 Competition Environment. In this task, I am aided by a guide Converting a virtual disk image: VDI or VMDK to an ISO you can distribute. Symptoms However, after getting through all the instructions, the live CD causes a kernel panic on boot on bare metal. In particular, the screen shows: [0.737348] cdrom: Uniform CD-ROM driver Revision: 3.20 [0.737503] sr 3:0:0:0: >Attached scsi CD-ROM sr0 [0.737638] sr 3:0:0:0: >Attached scsi generic sg2 type 5 [0.737771] Freeing unused kernel memory: 756k freed [0.738093] Write protecting the kernel text: 5960k [0.738155] Write protecting the kernel read-only data: 2424k [0.738224] NX-protecting the kernel data: 4280k Loading, please wait...

If anyone knows which packages needs installing/uninstalling at the .rootfs/ chroot directory stage, please let me know. Details on procedure Do note that after importing the .ova file into Virtualbox, the virtual machine is stored as a .vmdk file already, and not a .vdi file. I would like to point out some results of the procedure followed in case of any questions. This is after extracting the filesystem from the .raw file to the .rootfs/ directory mentioned in the blog. I changed the filesystem table as mentioned in the blog, then looked at the possible "kernel optimized for virtualization". However, I found that linux-image-generic was already installed. Also, when running the command dpkg-query --showformat='${Package}\n' -W 'vmware-tools*' (or dpkg-query --showformat='${Package}\n' -W '*-virtual'), no packages were found. Thus, I did not find any virtualization specific packages. I proceeded to generate the iso following the steps in the blog, and burned it to a DVD.

• Achieving A 1600 x 900 Resolution For (Guest OS) Ubuntu Under (Host OS) Windows 7

  - by panamack

  I am running Ubuntu 11.10 as a guest OS using VirtualBox 4.1.16 installed on Windows 7 Ultimate. On my laptop I'd like to be able to run Ubuntu in full screen mode at 1600 x 900. I only have options within the virtual machine to select 4:3 display settings such as 1600 x 1200, 1440 x 1050 etc. I have guest additions installed. At the windows command prompt, I tried typing: VBoxManage setextradata "Virtual Ubuntu Coursera ESSAAS" "CustomVideoMode1" "1600x900x16" This didn't work, still no 1600 x 900 res available in Ubuntu. I tried this having read the following section of the VirtualBox help (this also says something about a 'video mode hint feature' not sure what this means): 9.7. Advanced display configuration 9.7.1. Custom VESA resolutions Apart from the standard VESA resolutions, the VirtualBox VESA BIOS allows you to add up to 16 custom video modes which will be reported to the guest operating system. When using Windows guests with the VirtualBox Guest Additions, a custom graphics driver will be used instead of the fallback VESA solution so this information does not apply. Additional video modes can be configured for each VM using the extra data facility. The extra data key is called CustomVideoMode with x being a number from 1 to 16. Please note that modes will be read from 1 until either the following number is not defined or 16 is reached. The following example adds a video mode that corresponds to the native display resolution of many notebook computers: VBoxManage setextradata "VM name" "CustomVideoMode1" "1400x1050x16" The VESA mode IDs for custom video modes start at 0x160. In order to use the above defined custom video mode, the following command line has be supplied to Linux: vga = 0x200 | 0x160 vga = 864 For guest operating systems with VirtualBox Guest Additions, a custom video mode can be set using the video mode hint feature. UPDATE 02.06.12 I've just tried creating a new virtual machine using the same original disk image I had been given. This had Guest Additions v 4.1.6 installed and provided me with the 1600 x 900 full screen display I want. It's after I then install Guest Additions v 4.1.16 (the version included with my VirtualBox installation) that my only choices are 4:3 displays e.g. 1600 x 1200. Seems this is the cause.

• How can I minimize the amount my router slows down my Internet connection speed?

  - by Lord Torgamus

  Background I'm working with what I assume is a pretty common Internet setup: a cable modem, a wireless router and a few Internet-connected devices. Lately, I've started being more demanding on my Internet connection, and noticed that using my router slows down my download speeds considerably. I just kind of dealt with it until Zune Marketplace on the Xbox 360 told me that a movie was going to take well over ten hours to download, and I just didn't want to wait that long. Good little scientist that I am, I tried to reduce the problem down to one variable. The test As a control, I turned off all the devices in the house that use wireless Internet, and unplugged all the wired devices except for the Xbox. I also power-cycled both the modem and the router. I then tried to download the movie again, and was told that it would still take over ten hours. Next, I unplugged the router, and connected the Xbox directly to the modem. The movie downloaded in just over one hour. As far as I can tell, this means that my ISP, other cable users near me, the remote servers, anything wireless-related and my machines' disk speeds can't be at fault. A similar experiment that replaced the Xbox with a wired laptop produced similar results. To me, this says "the router is responsible for things taking around ten times longer to download." My question I'd still prefer to use the router for a few reasons: it's a pain to connect and disconnect everything every time there's a big file to download direct connection to the modem isn't good for security only one machine can be connected directly to the modem at a time What can I do to have fast connection speeds while still using the router? I don't mind turning other machines off, as long as I don't have to mess with power and ethernet cables. EDIT : After asking this followup question and then this one, I installed dd-wrt on my router, and I seem to be getting higher and more consistent speeds. Perhaps more importantly, my memory use is fairly constant. I know this isn't an answer — which is why I'm not posting it as an answer — but it is how I resolved the situation, and hopefully it'll be helpful for someone.

• What server setup for a small web development company? [closed]

  - by Giordano

  I co-own a company with a friend of mine and we have decided to buy a new server to support our business (our current server is an Asus EEE Box, working great but too limited :) ). I should mention that we are web developers but occasionally we do small-office sys admin. Thus, 99% of time we work on GNU/Linux (mainly Ubuntu) but from time to time we need to setup a Windows environment to assist some customers (e.g. setup a temporary SQL Server 2008). Our requirements: Low budget: we don't want the cheapest solution out there but we can't afford to spend too much. Budget could be ~1000-1500€ (before VAT) Robustness: we would like to setup a RAID array and maybe have an external disk where we can store backups Virtualization: we need to be able to setup few servers for development. The scenario is something like this (~8 appliances running in parallel): Redmine + GIT server Bacula server FTP server 3-4 virtual appliances that could be set up on demand to test our applications or support a customer. The appliances could be: LAMP, Tomcat+PostgreSQL, SQL Server Support: if something breaks down it shouldn't be too difficult to find a replacement. Now, given the main requirements, there are some doubts we need to clarify: Do you suggest to buy a prepackaged solution (for example a customized Dell PowerEdge T110 or T310) or to assemble the server by ourselves (buy the separate components)? What RAID configuration do you suggest? I was thinking of RAID1 (probably cheaper) or RAID5. should we buy a hardware RAID controller or is it ok to use a software RAID (mdadm)? In case, which controller do you suggest? What processor do you suggest (Intel Xeon, i3, i5, i7, AMD)? How much RAM? (I was thinking at least 8GB, ~1GB per appliance) What virtualization software do you recommend? VMWare seems to be the best choice, but what about XEN or KVM? We don't want to buy licenses at the moment so we would like to consider only free options. What OS do you recommend? We know Ubuntu, Debian, Gentoo very well (we would like to use Ubuntu Server), however it seems a lot of people goes for CentOS. Thanks in advance if you can help us with this! It's our first "serious" server so many doubts popped up :) Please feel free to add further recommendations if you have some to share ;) Have a nice day

• How to Create Auto Playlists in Windows Media Player 12

  - by DigitalGeekery

  Are you getting tired of the same old playlists in Windows Media Player? Today we’ll show you how to create dynamic auto playlists based on criteria you choose in WMP 12 in Windows 7. Auto Playlists In Library view, click on Create playlist dropdown arrow and select Create auto playlist. On the New Auto Playlist window type in a name for the playlist in the text box. Now we need to choose our criteria by which to filter your playlist. Select Click here to add criteria. For our example, we will create a playlist of songs that were added to the library in the last week from the Alternative genre. So, we will first select Date Added from the dropdown list. Many criteria will have addition options to configure. In the example below you will see that we have a few options to fine tune.   We will filter all the songs added to the library in the last 7 days. We will select Is After from the first dropdown list. Then select Last 7 Days from the second dropdown list. You can add multiple criteria to further filter your playlist. If you can’t find the criteria you are looking for, select “More” at the bottom of the dropdown list.   This will pull up a filter window with all the criteria. Select a filter and then click OK when finished.   From the Genre dropdown, we will select Alternative. If you’d like to add Pictures, Videos, or TV Shows to your auto playlists you can do so by selecting them from the dropdown list under And also include. You will then be able to select criteria for your pictures, videos, or TV shows from the dropdown list.   Finally, you can also add restrictions to your music such as the number of items, duration, or total size. We will limit the duration of our playlist to one hour by selecting Limit Total Duration To… Then type in 1 hour…Click OK.   Our library is automatically filtered and a playlist is created based on the criteria we selected. When additional songs are added to the Windows Media Player library, any of new songs that fit the criteria will automatically be added to the New Songs playlist. You can also save a copy of an auto playlist as a regular playlist. Switch to Playlists view by clicking Playlists from either the top menu or the navigation bar. Select the Play tab and then click Clear list to remove any tracks from the list pane.   Right-click on the playlist you want to save, select Add to, and then Play list. The songs from your auto playlist will appear as an Unsaved list on the list pane. Click Save list. Type in a name for your playlist. Your auto playlist will continue to change as you add or remove items from your Media Player library that meet the criteria you established. The new saved playlist we just created will stay as it is currently. Editing a Auto playlist is easy. Right-click on the playlist and select Edit. Now you are ready to enjoy your playlist. Conclusion Auto playlists are great way to keep your playlists fresh in Windows Media Player 12. Users can get creative and experiment with the wide variety of criteria to customize their listening experience.

• Looking For iPhone 4S Alternatives? Here Are 3 Smartphones You Should Consider

  - by Gopinath

  If you going to buy iPhone 4S on a two year contract in USA, Europe or Australia you may not find it expensive. But if you are planning to buy it in any other parts of the world, you will definitely feel the heat of ridiculous iPhone 4S price. In India iPhone 4S costs approximately costs $1000 which is 30% more than the price tag of an unlocked iPhone sold in USA. Personally I love iPhones as there is no match for the user experience provided by Apple as well as the wide range of really meaning applications available for iPhone. But it breaks heart to spend $1000 for a phone and I’m forced to look at alternates available in the market. Here are the four iPhone 4S alternates available in almost all the countries where we can buy iPhone 4S Google Galaxy Nexus The Galaxy Nexus is Google’s own Android smartphone manufactured by Samsung and sold under the brand name of Google Nexus. Galaxy Nexus is the pure Android phone available in the market without any bloat software or custom user interfaces like other Androids available in the market. Galaxy Nexus is also the first Android phone to be shipped with the latest version of Android OS, Ice Cream Sandwich. This phone is the benchmark for the rest of Android phones that are going to enter the market soon. In the words of Google this smartphone is called as “Galaxy Nexus: Simple. Beautiful. Beyond Smart.”.  BGR review summarizes the phone as This is almost comical at this point, but the Samsung Galaxy Nexus is my favourite Android device in the world. Easily replacing the HTC Rezound, the Motorola DROID RAZR, and Samsung Galaxy S II, the Galaxy Nexus champions in a brand new version of Android that pushes itself further than almost any other mobile OS in the industry. Samsung Galaxy S II The one single company that is able to sell more smartphones than Apple is Samsung. Samsung recently displaced Apple from the top smartphone seller spot and occupied it with loads of pride. Samsung’s Galaxy S II fits as one the best alternatives to Apple’s iPhone 4S with it’s beautiful design and remarkable performance. Engadget summarizes Samsung Galaxy S2 review as It’s the best Android smartphone yet, but more importantly, it might well be the best smartphone, period. Of course, a 4.3-inch screen size won’t suit everyone, no matter how stupendously thin the device that carries it may be, and we also can’t say for sure that the Galaxy S II would justify a long-term iOS user foresaking his investment into one ecosystem and making the leap to another. Nonetheless, if you’re asking us what smartphone to buy today, unconstrained by such externalities, the Galaxy S II would be the clear choice. Sometimes it’s just as simple as that. Nokia Lumia 800 Here comes unexpected Windows Phone in to the boxing ring. May be they are not as great as Androids available in the market today, but they are picking up very quickly. Especially the Nokia Lumia 800 seems to be first ever Windows Phone 7 aimed at competing serious with Androids and iPhones available in the market. There are reports that Nokia Lumia 800 is outselling all Androids in UK and few high profile tech blogs are calling it as the king of Windows Phone. Considering this phone while evaluating the alternative of iPhone 4S will not disappoint you. We assure. Droid RAZR Remember the Motorola Driod that swept entire Android market share couple of years ago? The first two version of Motorola Droids were the best in the market and they out performed almost every other Android phone those days. The invasion of Samsung Androids, Motorola lost it charm. With the recent release of Droid RAZR, Motorola seems to be in the right direction to reclaiming the prestige. Droid RAZR is the thinnest smartphone available in the market and it’s beauty is not just skin deep. Here is a review of the phone from Engadget blog the RAZR’s beauty is not only skin deep. The LTE radio, 1.2GHz dual-core processor and 1GB of RAM make sure this sleek number is ready to run with the big boys. It kept pace with, and in some cases clearly outclassed its high-end competition. Despite its deficiencies in the display department and underwhelming battery life, the RAZR looks to be a perfectly viable alternative when considering the similarly-pricey Rezound and Galaxy Nexus Further Reading So we have seen the four alternates of iPhone 4S available in the market and I personally love to buy a Samsung smartphone if I’m don’t have money to afford an iPhone 4S. If you are interested in deep diving into the alternates, here few links that help you do more research Apple iPhone 4S vs. Samsung Galaxy Nexus vs. Motorola Droid RAZR: How Their Specs Compare by Huffington Post Nokia Lumia 800 vs. iPhone 4S vs. Nexus Galaxy: Spec Smackdown by PC World Browser Speed Test: Nokia Lumia 800 vs. iPhone 4S vs. Samsung Galaxy S II – by Gizmodo iPhone 4S vs Samsung Galaxy S II by pocket lint Apple iPhone 4S vs. Samsung Galaxy S II by techie buzz This article titled,Looking For iPhone 4S Alternatives?

• SQL SERVER – 2008 – Introduction to Snapshot Database – Restore From Snapshot

  - by pinaldave

  Snapshot database is one of the most interesting concepts that I have used at some places recently. Here is a quick definition of the subject from Book On Line: A Database Snapshot is a read-only, static view of a database (the source database). Multiple snapshots can exist on a source database and can always reside on the same server instance as the database. Each database snapshot is consistent, in terms of transactions, with the source database as of the moment of the snapshot’s creation. A snapshot persists until it is explicitly dropped by the database owner. If you do not know how Snapshot database work, here is a quick note on the subject. However, please refer to the official description on Book-on-Line for accuracy. Snapshot database is a read-only database created from an original database called the “source database”. This database operates at page level. When Snapshot database is created, it is produced on sparse files; in fact, it does not occupy any space (or occupies very little space) in the Operating System. When any data page is modified in the source database, that data page is copied to Snapshot database, making the sparse file size increases. When an unmodified data page is read in the Snapshot database, it actually reads the pages of the original database. In other words, the changes that happen in the source database are reflected in the Snapshot database. Let us see a simple example of Snapshot. In the following exercise, we will do a few operations. Please note that this script is for demo purposes only- there are a few considerations of CPU, DISK I/O and memory, which will be discussed in the future posts. Create Snapshot Delete Data from Original DB Restore Data from Snapshot First, let us create the first Snapshot database and observe the sparse file details. USE master GO -- Create Regular Database CREATE DATABASE RegularDB GO USE RegularDB GO -- Populate Regular Database with Sample Table CREATE TABLE FirstTable (ID INT, Value VARCHAR(10)) INSERT INTO FirstTable VALUES(1, 'First'); INSERT INTO FirstTable VALUES(2, 'Second'); INSERT INTO FirstTable VALUES(3, 'Third'); GO -- Create Snapshot Database CREATE DATABASE SnapshotDB ON (Name ='RegularDB', FileName='c:\SSDB.ss1') AS SNAPSHOT OF RegularDB; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO Now let us see the resultset for the same. Now let us do delete something from the Original DB and check the same details we checked before. -- Delete from Regular Database DELETE FROM RegularDB.dbo.FirstTable; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO When we check the details of sparse file created by Snapshot database, we will find some interesting details. The details of Regular DB remain the same. It clearly shows that when we delete data from Regular/Source DB, it copies the data pages to Snapshot database. This is the reason why the size of the snapshot DB is increased. Now let us take this small exercise to  the next level and restore our deleted data from Snapshot DB to Original Source DB. -- Restore Data from Snapshot Database USE master GO RESTORE DATABASE RegularDB FROM DATABASE_SNAPSHOT = 'SnapshotDB'; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO -- Clean up DROP DATABASE [SnapshotDB]; DROP DATABASE [RegularDB]; GO Now let us check the details of the select statement and we can see that we are successful able to restore the database from Snapshot Database. We can clearly see that this is a very useful feature in case you would encounter a good business that needs it. I would like to request the readers to suggest more details if they are using this feature in their business. Also, let me know if you think it can be potentially used to achieve any tasks.

• Use ASP.NET 4 Browser Definitions with ASP.NET 3.5

  - by Stephen Walther

  We updated the browser definitions files included with ASP.NET 4 to include information on recent browsers and devices such as Google Chrome and the iPhone. You can use these browser definition files with earlier versions of ASP.NET such as ASP.NET 3.5. The updated browser definition files, and instructions for installing them, can be found here: http://aspnet.codeplex.com/releases/view/41420 The changes in the browser definition files can cause backwards compatibility issues when you upgrade an ASP.NET 3.5 web application to ASP.NET 4. If you encounter compatibility issues, you can install the old browser definition files in your ASP.NET 4 application. The old browser definition files are included in the download file referenced above. What’s New in the ASP.NET 4 Browser Definition Files The complete set of browsers supported by the new ASP.NET 4 browser definition files is represented by the following figure:     If you look carefully at the figure, you’ll notice that we added browser definitions for several types of recent browsers such as Internet Explorer 8, Firefox 3.5, Google Chrome, Opera 10, and Safari 4. Furthermore, notice that we now include browser definitions for several of the most popular mobile devices: BlackBerry, IPhone, IPod, and Windows Mobile (IEMobile). The mobile devices appear in the figure with a purple background color. To improve performance, we removed a whole lot of outdated browser definitions for old cell phones and mobile devices. We also cleaned up the information contained in the browser files. Here are some of the browser features that you can detect: Are you a mobile device? <%=Request.Browser.IsMobileDevice %> Are you an IPhone? <%=Request.Browser.MobileDeviceModel == "IPhone" %> What version of JavaScript do you support? <%=Request.Browser["javascriptversion"] %> What layout engine do you use? <%=Request.Browser["layoutEngine"] %>   Here’s what you would get if you displayed the value of these properties using Internet Explorer 8: Here’s what you get when you use Google Chrome: Testing Browser Settings When working with browser definition files, it is useful to have some way to test the capability information returned when you request a page with different browsers. You can use the following method to return the HttpBrowserCapabilities the corresponds to a particular user agent string and set of browser headers: public HttpBrowserCapabilities GetBrowserCapabilities(string userAgent, NameValueCollection headers) { HttpBrowserCapabilities browserCaps = new HttpBrowserCapabilities(); Hashtable hashtable = new Hashtable(180, StringComparer.OrdinalIgnoreCase); hashtable[string.Empty] = userAgent; // The actual method uses client target browserCaps.Capabilities = hashtable; var capsFactory = new System.Web.Configuration.BrowserCapabilitiesFactory(); capsFactory.ConfigureBrowserCapabilities(headers, browserCaps); capsFactory.ConfigureCustomCapabilities(headers, browserCaps); return browserCaps; } At the end of this blog entry, there is a link to download a simple Visual Studio 2008 project – named Browser Definition Test -- that uses this method to display capability information for arbitrary user agent strings. For example, if you enter the user agent string for an iPhone then you get the results in the following figure: The Browser Definition Test application enables you to submit a user-agent string and display a table of browser capabilities information. The browser definition files contain sample user-agent strings for each browser definition. I got the iPhone user-agent string from the comments in the iphone.browser file. Enumerating Browser Definitions Someone asked in the comments whether or not there is a way to enumerate all of the browser definitions. You can do this if you ware willing to use a little reflection and read a private property. The browser definition files in the config\browsers folder get parsed into a class named BrowserCapabilitesFactory. After you run the aspnet_regbrowsers tool, you can see the source for this class in the config\browser folder by opening a file named BrowserCapsFactory.cs. The BrowserCapabilitiesFactoryBase class has a protected property named BrowserElements that represents a Hashtable of all of the browser definitions. Here's how you can read this protected property and display the ID for all of the browser definitions: var propInfo = typeof(BrowserCapabilitiesFactory).GetProperty("BrowserElements", BindingFlags.NonPublic | BindingFlags.Instance); Hashtable browserDefinitions = (Hashtable)propInfo.GetValue(new BrowserCapabilitiesFactory(), null); foreach (var key in browserDefinitions.Keys) { Response.Write("" + key); } If you run this code using Visual Studio 2008 then you get the following results: You get a huge number of outdated browsers and devices. In all, 449 browser definitions are listed. If you run this code using Visual Studio 2010 then you get the following results: In the case of Visual Studio 2010, all the old browsers and devices have been removed and you get only 19 browser definitions. Conclusion The updated browser definition files included in ASP.NET 4 provide more accurate information for recent browsers and devices. If you would like to test the new browser definitions with different user-agent strings then I recommend that you download the Browser Definition Test project: Browser Definition Test Project

• Our Look at the Internet Explorer 9 Platform Preview

  - by Asian Angel

  Have you been hearing all about Microsoft’s work on Internet Explorer 9 and are curious about it? If you are wanting a taste of the upcoming release then join us as we take a look at the Internet Explorer 9 Platform Preview. Note: Windows Vista and Server 2008 users may need to install a Platform Update (see link at bottom for more information). Getting Started If you are curious about the systems that the platform preview will operate on here is an excerpt from the FAQ page (link provided below). There are two important points of interest here: The platform preview does not replace your regular Internet Explorer installation The platform preview (and the final version of Internet Explorer 9) will not work on Windows XP There really is not a lot to the install process…basically all that you will have to deal with is the “EULA Window” and the “Install Finished Window”. Note: The platform preview will install to a “Program Files Folder” named “Internet Explorer Platform Preview”. Internet Explorer 9 Platform Preview in Action When you start the platform preview up for the first time you will be presented with the Internet Explorer 9 Test Drive homepage. Do not be surprised that there is not a lot to the UI at this time…but you can get a good idea of how Internet Explorer will act. Note: You will not be able to alter the “Homepage” for the platform preview. Of the four menus available there are two that will be of interest to most people…the “Page & Debug Menus”. If you go to navigate to a new webpage you will need to go through the “Page Menu” unless you have installed the Address Bar Mini-Tool (shown below). Want to see what a webpage will look like in an older version of Internet Explorer? Then choose your version in the “Debug Menu”. We did find it humorous that IE6 was excluded from the choices offered. Here is what the URL entry window looks like if you are using the “Page Menu” to navigate between websites. Here is the main page of the site here displayed in “IE9 Mode”…looking good. Here is the main page viewed in “Forced IE5 Document Mode”. There were some minor differences (colors, sidebar, etc.) in how the main page displayed in comparison to “IE9 Mode”. Being able to switch between modes makes for an interesting experience… As you can see there is not much to the “Context Menu” at the moment. Notice the slightly altered icon for the platform preview… “Add” an Address Bar of Sorts If you would like to use a “make-shift” Address Bar with the platform preview you can set up the portable file (IE9browser.exe) for the Internet Explorer 9 Test Platform Addressbar Mini-Tool. Just place it in an appropriate folder, create a shortcut for it, and it will be ready to go. Here is a close look at the left side of the Address Bar Mini-Tool. You can try to access “IE Favorites” but may have sporadic results like those we experienced during our tests. Note: The Address Bar Mini-Tool will not line up perfectly with the platform preview but still makes a nice addition. And a close look at the right side of the Address Bar Mini-Tool. In order to completely shut down the Address Bar Mini-Tool you will need to click on “Close”. Each time that you enter an address into the Address Bar Mini-Tool it will open a new window/instance of the platform preview. Note: During our tests we noticed that clicking on “Home” in the “Page Menu” opened the previously viewed website but once we closed and restarted the platform preview the test drive website was the starting/home page again. Even if the platform preview is not running the Address Bar Mini-Tool can still run as shown here. Note: You will not be able to move the Address Bar Mini-Tool from its’ locked-in position at the top of the screen. Now for some fun. With just the Address Bar Mini-Tool open you can enter an address and cause the platform preview to open. Here is our example from above now open in the platform preview…good to go. Conclusion During our tests we did experience the occasional crash but overall we were pleased with the platform preview’s performance. The platform preview handled rather well and definitely seemed much quicker than Internet Explorer 8 on our test system (a definite bonus!). If you are an early adopter then this could certainly get you in the mood for the upcoming beta releases!

• Remove Office 2010 Beta and Reinstall Office 2007

  - by Matthew Guay

  Have you tried out the Office 2010 beta, but want to go back to Office 2007?  Here’s a step-by-step tutorial on how to remove your Office 2010 beta and reinstall your Office 2007. The Office 2010 beta will expire on October 31, 2010, at which time you may see a dialog like the one below.  At that time, you will need to either upgrade to the final release of Office 2010, or reinstall your previous version of Office. Our computer was running the Office 2010 Home and Business Click to Run beta, and after uninstalling it we reinstalled Office 2007 Home and Student.  This was a Windows Vista computer, but the process will be exactly the same on Windows XP, Vista, or Windows 7.  Additionally, the process to reinstall Office 2007 will be exactly the same regardless of the edition of Office 2007 you’re using. However, please note that if you are running a different edition of Office 2010, especially the 64 bit version, the process may be slightly different.  We will cover this scenario in another article. Remove Office 2010 Click to Run Beta: To remove Office 2010 Click to Run Beta, open Control Panel and select Uninstall a Program. If your computer is running Windows 7, enter “Uninstall a program” in your Start menu search. Scroll down, select “Microsoft Office Click-to-Run 2010 (Beta)”, and click the Uninstall button on the toolbar.  Note that there will be two entries for Office, so make sure to select the “Click-to-Run” entry. This will automatically remove all of Office 2010 and its components.  Click Yes to confirm you want to remove it. Office 2010 beta uninstalled fairly quickly, and a reboot will be required.  Once your computer is rebooted, Office 2010 will be entirely removed. Reinstall Office 2007 Now, you’re to the easy part.  Simply insert your Office 2007 CD, and it should automatically startup the setup.  If not, open Computer and double-click on your CD drive.   Now, double-click on setup.exe to start the installation. Enter your product key, and click Continue…   Click Install Now, or click Customize if you want to change the default installation settings. Wait while Office 2007 installs…it takes around 15 to 20 minutes in our experience.  Once it’s finished  close the installer. Now, open one of the Office applications.  A popup will open asking you to activate Office.  Make sure you’re connected to the internet, and click next; otherwise, you can select to activate over the phone if you do not have internet access. This should only take a minute, and Office 2007 will be activated and ready to run. Everything should work just as it did before you installed Office 2010.  Enjoy! Office Updates Make sure to install the latest updates for Office 2007, as these are not included in your disk.  Check Windows Update (search for Windows Update in the Start menu search), and install all of the available updates for Office 2007, including Service Pack 2. Conclusion This is a great way to keep using Office even if you don’t decide to purchase Office 2010 after it is released.  Additionally, if you’re were using another version of Office, such as Office 2003, then reinstall it as normal after following the steps to remove Office 2010.

• Framework 4 Features: Summary of Security enhancements

  - by Anthony Shorten

  In the last log entry I mentioned one of the new security features in Oracle Utilities Application Framework 4.0.1. Security is one of the major "tent poles" (to borrow a phrase from Steve Jobs) in this release of the framework. There are a number of security related enhancements requested by customers and as a result of internal reviews that we have introduced. Here is a summary of some of the security enchancements we have added in this release: Security Cache Changes - Security authorization information is automatically cached on the server for performance reasons (security is checked for every single call the product makes for all modes of access). Prior to this release the cache auto-refreshed every 30 minutes (or so). This has beem made more nimble by supporting a cache refresh every minute (or so). This means authorization changes are reflected quicker than before. Business Level security - Business Services are configurable services that are based upon Application Services. Typically, the business service inherited its security profile from its parent service. Whilst this is sufficient for most needs, it is now required to further specify security on the Business Service definition itself. This will allow granular security and allow the same application service to be exposed as different Business Services with their own security. This is particularly useful when you base a Business Service on a query zone. User Propogation - As with other client server applications, the database connections are pooled and shared as needed. This means that a common database user is used to access the database from the pool to allow sharing. Unfortunently, this means that tracability at the database level is that much harder. In Oracle Utilities Application Framework V4 the end userid is now propogated to the database using the CLIENT_IDENTIFIER as part of the Oracle JDBC connection API. This not only means that the common database userid is still used but the end user is indentifiable for the duration of the database call. This can be used for monitoring or to hook into Oracle's database security products. This enhancement is only available to Oracle Database customers. Enhanced Security Definitions - Security Administrators use the product browser front end to control access rights of defined users. While this is sufficient for most sites, a new security portal has been introduced to speed up the maintenance of security information. Oracle Identity Manager Integration - With the popularity of Oracle's Identity Management Suite, the Framework now provides an integration adapter and Identity Manager Generic Transport Connector (GTC) to allow users and group membership to be provisioned to any Oracle Utilities Application Framework based product from Oracle's Identity Manager. This is also available for Oracle Utilties Application Framework V2.2 customers. Refer to My Oracle Support KBid 970785.1 - Oracle Identity Manager Integration Overview. Audit On Inquiry - Typically the configurable audit facility in the Oracle Utilities Application Framework is used to audit changes to records. In Oracle Utilities Application Framework the Business Services and Service Scripts could be configured to audit inquiries as well. Now it is possible to attach auditing capabilities to zones on the product (including base package ones). Time Zone Support - In some of the Oracle Utilities Application Framework based products, the timezone of the end user is a factor in the processing. The user object has been extended to allow the recording of time zone information for use in product functionality. JAAS Suport - Internally the Oracle Utilities Application Framework uses a number of techniques to validate and transmit security information across the architecture. These various methods have been reconciled into using Java Authentication and Authorization Services for standardized security. This is strictly an internal change with no direct on how security operates externally. JMX Based Cache Management - In the last bullet point, I mentioned extra security applied to cache management from the browser. Alternatively a JMX based interface is now provided to allow IT operations to control the cache without the browser interface. This JMX capability can be initiated from a JSR120 compliant JMX console or JMX browser. I will be writing another more detailed blog entry on the JMX enhancements as it is quite a change and an exciting direction for the product line. Data Patch Permissions - The database installer provided with the product required lower levels of security for some operations. At some sites they wanted the ability for non-DBA's to execute the utilities in a controlled fashion. The framework now allows feature configuration to allow delegation for patch execution. User Enable Support - At some sites, the use of temporary staff such as contractors is commonplace. In this scenario, temporary security setups were required and used. A potential issue has arisen when the contractor left the company. Typically the IT group would remove the contractor from the security repository to prevent login using that contractors userid but the userid could NOT be removed from the authorization model becuase of audit requirements (if any user in the product updates financials or key data their userid is recorded for audit purposes). It is now possible to effectively diable the user from the security model to prevent any use of the useridwhilst retaining audit information. These are a subset of the security changes in Oracle Utilities Application Framework. More details about the security capabilities of the product is contained in My Oracle Support KB Id 773473.1 - Oracle Utilities Application Framework Security Overview.

• mysql not starting

  - by Eiriks

  I have a server running on rackspace.com, it been running for about a year (collecting data for a project) and no problems. Now it seems mysql froze (could not connect either through ssh command line, remote app (sequel pro) or web (pages using the db just froze). I got a bit eager to fix this quick and rebooted the virtual server, running ubuntu 10.10. It is a small virtual LAMP server (10gig storage - I'm only using 1, 256mb ram -has not been a problem). Now after the reboot, I cannot get mysql to start again. service mysql status mysql stop/waiting I believe this just means mysql is not running. How do I get this running again? service mysql start start: Job failed to start No. Just typing 'mysql' gives: mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) There is a .sock file in this folder, 'ls -l' gives: srwxrwxrwx 1 mysql mysql 0 2012-12-01 17:20 mysqld.sock From googleing this for a while now, I see that many talk about the logfile and my.cnf.

• Fix Windows Computer Problems with Microsoft Fix it Center

  - by Matthew Guay

  Fixing computer problems can often be difficult, but Microsoft is aiming to make it as simple as a couple clicks with.  Here’s how you can easily fix computer problems with Microsoft’s new Fix it Center Beta. Last year Microsoft began offering small Fix it scripts that you could download and run to help solve common computer problems automatically.  These were added to some of the most visited Windows help pages, and helped fix problems with things such as printing errors and Aero glass support.  Now, the Fix it scripts have been bundled together with the Fix it Center, making fixing your computer even easier.  This free tool works great on all editions of Windows XP, Vista, and Windows 7. Note: The Fix it Center is currently in beta, so only run if you are comfortable running beta software. Getting Started Download the Fix it Center installer (link below), and install as normal. The installer will download the remaining components, and then finish the installation. In Windows XP, if you have not yet installed .NET 2.0, you may see the following prompt.  Click Yes to go to the download site, and once you’ve installed .NET 2.0, run the Fix it Center setup again. Also, the Fix it Center uses PowerShell to automate its fixes, but if it is not installed yet the installer will automatically download and install it. Find Fixes for Your PC Once Fix it Center is installed, you can personalize it for your computer.  Select Now, and the click Next. It will scan your computer for problems with known solutions, and will offer to go ahead and install these troubleshooters.  If you choose to not install them, you can always download them from within the Fix it Center at a later time. While those troubleshooters are downloading, you can create a Fix it account.  This will give you additional help and support, and let you review Fix it solutions for all your computers from an online dashboard.  You need a Windows Live ID to create an account. Also, choose whether or not to send information to Microsoft about your hardware and software problems. Get Problems Fixed Now that the Fix it Center is installed and has identified issues on your computer, it’s time to get the problems fixed.  Here’s the default front screen in Windows 7, showing all of the available fixes. And here’s the Fix it Center running in Windows XP. Select one of the Troubleshooters to see more information about it, and click Run to start it. You can choose to either detect problems and have them fixed automatically, or you can choose for the Fix it Center to show you the solutions and let you choose whether to apply them or not.  The defaults usually work good, and only take a couple minutes to apply the fixes, but you can select your own fixes if you’d rather be in control. It will scan your computer for known problems in this area, and then will show you the results.  Here, Fix it determined that startup programs may be causing performance issues.  Select Start System Configuration, and uncheck any of the programs you do not usually use. Once you’ve run a troubleshooter, you can see the issues it checked for and any problems it discovered. If you created the online account, you can also choose to view the details online.  This will show all of your computers with Fix it Center and the fixes you’ve run on them.   Conclusion Whether you’re a power user or new to computers, sometimes it’s best to just get your problems fixed and go on with life instead of digging through the registry, forums, and hacking your way to a solution.  Remember the service is still in beta and may not work perfectly or solve your issues every time. But it’s something cool and worth a look.

• UCM 11g is 4 days old!

  - by kyle.hatlestad

  Ok...so I missed posting a blog entry when UCM 11g and the entire ECM suite released on Tuesday. Hopefully you've already seen the announcements on any number of the Oracle ECM blogs out there such as ECM Alerts, Fusion ECM, bex huff, or C4. So I won't bore you with the same talking points like 179 million check-ins per day or 124 web site page hits per second. Instead, I thought I'd show some screenshots of the new features in UCM and URM 11g. WebLogic Server and Enterprise Manager So probably the biggest change in 11g is UCM and URM now run on top of the WebLogic Server application server. This is a huge step as ECM is now on a standard platform with the rest of Oracle Fusion Middleware which makes installation, configuration, and integration consistent among all the products. From a feature perspective, it's also beneficial because it's now integrated with Oracle Enterprise Manager. Enterprise Manager provides a lot of provisioning control over servers as well as performance monitoring and access to logs and debugging information. Desktop Integration Suite Desktop Integration Suite got a complete overhaul for 11g. It exposes a lot more features within Windows Explorer such as saved searches, workflow queue, and checked-out items. It also now support metadata pop-up screens to let users fill in additional metadata when they drag-n-drop files in! And the integration within Office applications has changed significantly by introducing a dedicated UCM menu to do open, save, compare, etc. Site Studio for External Applications In UCM Site Studio 10gR4, a major architectural shift was introduced which brought several new objects such as elements, region definitions, region templates, and placeholder definitions. This truly separated the content from the display and from the definition. It also allowed separation of the content from needing to be rendered on a complete Site Studio page. Well, the new Site Studio for External Applications takes advantage of that architecture and introduces pre-built tags and plug-ins to JDeveloper to allow to go from simply adding a content area to your web application page to building an entire web site, just like you would have done in Site Studio Designer. In addition to these changes, enhancements to the core Site Studio have been added as well. One of the big ones is called Designer Mode which allows power-users to bypass the standard rules defined by the placeholder definition or template and perform any number of additional actions. This reduces the need to go back to Site Studio Designer or JDeveloper to make more advanced changes to the site. Dashboards As part of the updated records management functionality in both UCM and URM, users can now set a dashboard view on their home page to surface common functions in a single view. It has pre-built "portlets" users can choose from to display and organize they way they want. Behind the scenes, these dashboards are stored as Content Folios. So the dashboards themselves are content items that can be revisioned and shared between users. And new dashboard portlets can be easily added (like the User Profile one in the screenshots) by getting a copy of an existing one, modifying the display, and then checking it in as a new one to select from. URM Interface Enhancements URM includes several new UI and usability enhancements in 11g. There is a new view for physical records, a place to configure "favorite" items to quickly get to, and new placement of the records management menu. BI Publisher Reports Records management in UCM and URM now offer reports generated through embedded BI Publisher. Templates are controlled by rich text files checked directly into the repository, so they can be easily modified. Other Features A new Inbound Refinery conversion option is available that does native Microsoft Office HTML conversion. If your IBR is on Windows and you have the native applications loaded, the IBR can use them to produce HTML. A new GUI template editor for Dynamic Converter is available. It's written in Java so is available through all the supported browsers and platforms. The original ActiveX based editor is also still available. The Component Manager interface has changed to help provide an easier and more descriptive way to enable core components that are installed along with UCM. All of the supported components are immediately available to turn on and do not have to be installed separately as in previous versions. My Downloads is located in the My Content Server menu and provides for easy download of client installs including Desktop Integration Suite and Site Studio Designer. Well, hopefully that gives you a taste for some of the new things in 11g. We're all pretty excited here at Oracle about all the new changes and enhancements. Over the next few months I hope to highlight some of these features more in-depth, so keep your eye out for those posts.

• 8 Backup Tools Explained for Windows 7 and 8

  - by Chris Hoffman

  Backups on Windows can be confusing. Whether you’re using Windows 7 or 8, you have quite a few integrated backup tools to think about. Windows 8 made quite a few changes, too. You can also use third-party backup software, whether you want to back up to an external drive or back up your files to online storage. We won’t cover third-party tools here — just the ones built into Windows. Backup and Restore on Windows 7 Windows 7 has its own Backup and Restore feature that lets you create backups manually or on a schedule. You’ll find it under Backup and Restore in the Control Panel. The original version of Windows 8 still contained this tool, and named it Windows 7 File Recovery. This allowed former Windows 7 users to restore files from those old Windows 7 backups or keep using the familiar backup tool for a little while. Windows 7 File Recovery was removed in Windows 8.1. System Restore System Restore on both Windows 7 and 8 functions as a sort of automatic system backup feature. It creates backup copies of important system and program files on a schedule or when you perform certain tasks, such as installing a hardware driver. If system files become corrupted or your computer’s software becomes unstable, you can use System Restore to restore your system and program files from a System Restore point. This isn’t a way to back up your personal files. It’s more of a troubleshooting feature that uses backups to restore your system to its previous working state. Previous Versions on Windows 7 Windows 7′s Previous Versions feature allows you to restore older versions of files — or deleted files. These files can come from backups created with Windows 7′s Backup and Restore feature, but they can also come from System Restore points. When Windows 7 creates a System Restore point, it will sometimes contain your personal files. Previous Versions allows you to extract these personal files from restore points. This only applies to Windows 7. On Windows 8, System Restore won’t create backup copies of your personal files. The Previous Versions feature was removed on Windows 8. File History Windows 8 replaced Windows 7′s backup tools with File History, although this feature isn’t enabled by default. File History is designed to be a simple, easy way to create backups of your data files on an external drive or network location. File History replaces both Windows 7′s Backup and Previous Versions features. Windows System Restore won’t create copies of personal files on Windows 8. This means you can’t actually recover older versions of files until you enable File History yourself — it isn’t enabled by default. System Image Backups Windows also allows you to create system image backups. These are backup images of your entire operating system, including your system files, installed programs, and personal files. This feature was included in both Windows 7 and Windows 8, but it was hidden in the preview versions of Windows 8.1. After many user complaints, it was restored and is still available in the final version of Windows 8.1 — click System Image Backup on the File History Control Panel. Storage Space Mirroring Windows 8′s Storage Spaces feature allows you to set up RAID-like features in software. For example, you can use Storage Space to set up two hard disks of the same size in a mirroring configuration. They’ll appear as a single drive in Windows. When you write to this virtual drive, the files will be saved to both physical drives. If one drive fails, your files will still be available on the other drive. This isn’t a good long-term backup solution, but it is a way of ensuring you won’t lose important files if a single drive fails. Microsoft Account Settings Backup Windows 8 and 8.1 allow you to back up a variety of system settings — including personalization, desktop, and input settings. If you’re signing in with a Microsoft account, OneDrive settings backup is enabled automatically. This feature can be controlled under OneDrive > Sync settings in the PC settings app. This feature only backs up a few settings. It’s really more of a way to sync settings between devices. OneDrive Cloud Storage Microsoft hasn’t been talking much about File History since Windows 8 was released. That’s because they want people to use OneDrive instead. OneDrive — formerly known as SkyDrive — was added to the Windows desktop in Windows 8.1. Save your files here and they’ll be stored online tied to your Microsoft account. You can then sign in on any other computer, smartphone, tablet, or even via the web and access your files. Microsoft wants typical PC users “backing up” their files with OneDrive so they’ll be available on any device. You don’t have to worry about all these features. Just choose a backup strategy to ensure your files are safe if your computer’s hard disk fails you. Whether it’s an integrated backup tool or a third-party backup application, be sure to back up your files.

• Change the User Interface Language in Ubuntu

  - by Matthew Guay

  Would you like to use your Ubuntu computer in another language?  Here’s how you can easily change your interface language in Ubuntu. Ubuntu’s default install only includes a couple languages, but it makes it easy to find and add a new interface language to your computer.  To get started, open the System menu, select Administration, and then click Language Support. Ubuntu may ask if you want to update or add components to your current default language when you first open the dialog.  Click Install to go ahead and install the additional components, or you can click Remind Me Later to wait as these will be installed automatically when you add a new language. Now we’re ready to find and add an interface language to Ubuntu.  Click Install / Remove Languages to add the language you want. Find the language you want in the list, and click the check box to install it.  Ubuntu will show you all the components it will install for the language; this often includes spellchecking files for OpenOffice as well.  Once you’ve made your selection, click Apply Changes to install your new language.  Make sure you’re connected to the internet, as Ubuntu will have to download the additional components you’ve selected. Enter your system password when prompted, and then Ubuntu will download the needed languages files and install them.   Back in the main Language & Text dialog, we’re now ready to set our new language as default.  Find your new language in the list, and then click and drag it to the top of the list. Notice that Thai is the first language listed, and English is the second.  This will make Thai the default language for menus and windows in this account.  The tooltip reminds us that this setting does not effect system settings like currency or date formats. To change these, select the Text Tab and pick your new language from the drop-down menu.  You can preview the changes in the bottom Example box. The changes we just made will only affect this user account; the login screen and startup will not be affected.  If you wish to change the language in the startup and login screens also, click Apply System-Wide in both dialogs.  Other user accounts will still retain their original language settings; if you wish to change them, you must do it from those accounts. Once you have your new language settings all set, you’ll need to log out of your account and log back in to see your new interface language.  When you re-login, Ubuntu may ask you if you want to update your user folders’ names to your new language.  For example, here Ubuntu is asking if we want to change our folders to their Thai equivalents.  If you wish to do so, click Update or its equivalents in your language. Now your interface will be almost completely translated into your new language.  As you can see here, applications with generic names are translated to Thai but ones with specific names like Shutter keep their original name. Even the help dialogs are translated, which makes it easy for users around to world to get started with Ubuntu.  Once again, you may notice some things that are still in English, but almost everything is translated. Adding a new interface language doesn’t add the new language to your keyboard, so you’ll still need to set that up.  Check out our article on adding languages to your keyboard to get this setup. If you wish to revert to your original language or switch to another new language, simply repeat the above steps, this time dragging your original or new language to the top instead of the one you chose previously. Conclusion Ubuntu has a large number of supported interface languages to make it user-friendly to people around the globe.  And since you can set the language for each user account, it’s easy for multi-lingual individuals to share the same computer. Or, if you’re using Windows, check out our article on how you can Change the User Interface Language in Vista or Windows 7, too!

• 8 Things You Can Do In Android’s Developer Options

  - by Chris Hoffman

  The Developer Options menu in Android is a hidden menu with a variety of advanced options. These options are intended for developers, but many of them will be interesting to geeks. You’ll have to perform a secret handshake to enable the Developer Options menu in the Settings screen, as it’s hidden from Android users by default. Follow the simple steps to quickly enable Developer Options. Enable USB Debugging “USB debugging” sounds like an option only an Android developer would need, but it’s probably the most widely used hidden option in Android. USB debugging allows applications on your computer to interface with your Android phone over the USB connection. This is required for a variety of advanced tricks, including rooting an Android phone, unlocking it, installing a custom ROM, or even using a desktop program that captures screenshots of your Android device’s screen. You can also use ADB commands to push and pull files between your device and your computer or create and restore complete local backups of your Android device without rooting. USB debugging can be a security concern, as it gives computers you plug your device into access to your phone. You could plug your device into a malicious USB charging port, which would try to compromise you. That’s why Android forces you to agree to a prompt every time you plug your device into a new computer with USB debugging enabled. Set a Desktop Backup Password If you use the above ADB trick to create local backups of your Android device over USB, you can protect them with a password with the Set a desktop backup password option here. This password encrypts your backups to secure them, so you won’t be able to access them if you forget the password. Disable or Speed Up Animations When you move between apps and screens in Android, you’re spending some of that time looking at animations and waiting for them to go away. You can disable these animations entirely by changing the Window animation scale, Transition animation scale, and Animator duration scale options here. If you like animations but just wish they were faster, you can speed them up. On a fast phone or tablet, this can make switching between apps nearly instant. If you thought your Android phone was speedy before, just try disabling animations and you’ll be surprised how much faster it can seem. Force-Enable FXAA For OpenGL Games If you have a high-end phone or tablet with great graphics performance and you play 3D games on it, there’s a way to make those games look even better. Just go to the Developer Options screen and enable the Force 4x MSAA option. This will force Android to use 4x multisample anti-aliasing in OpenGL ES 2.0 games and other apps. This requires more graphics power and will probably drain your battery a bit faster, but it will improve image quality in some games. This is a bit like force-enabling antialiasing using the NVIDIA Control Panel on a Windows gaming PC. See How Bad Task Killers Are We’ve written before about how task killers are worse than useless on Android. If you use a task killer, you’re just slowing down your system by throwing out cached data and forcing Android to load apps from system storage whenever you open them again. Don’t believe us? Enable the Don’t keep activities option on the Developer options screen and Android will force-close every app you use as soon as you exit it. Enable this app and use your phone normally for a few minutes — you’ll see just how harmful throwing out all that cached data is and how much it will slow down your phone. Don’t actually use this option unless you want to see how bad it is! It will make your phone perform much more slowly — there’s a reason Google has hidden these options away from average users who might accidentally change them. Fake Your GPS Location The Allow mock locations option allows you to set fake GPS locations, tricking Android into thinking you’re at a location where you actually aren’t. Use this option along with an app like Fake GPS location and you can trick your Android device and the apps running on it into thinking you’re at locations where you actually aren’t. How would this be useful? Well, you could fake a GPS check-in at a location without actually going there or confuse your friends in a location-tracking app by seemingly teleporting around the world. Stay Awake While Charging You can use Android’s Daydream Mode to display certain apps while charging your device. If you want to force Android to display a standard Android app that hasn’t been designed for Daydream Mode, you can enable the Stay awake option here. Android will keep your device’s screen on while charging and won’t turn it off. It’s like Daydream Mode, but can support any app and allows users to interact with them. Show Always-On-Top CPU Usage You can view CPU usage data by toggling the Show CPU usage option to On. This information will appear on top of whatever app you’re using. If you’re a Linux user, the three numbers on top probably look familiar — they represent the system load average. From left to right, the numbers represent your system load over the last one, five, and fifteen minutes. This isn’t the kind of thing you’d want enabled most of the time, but it can save you from having to install third-party floating CPU apps if you want to see CPU usage information for some reason. Most of the other options here will only be useful to developers debugging their Android apps. You shouldn’t start changing options you don’t understand. If you want to undo any of these changes, you can quickly erase all your custom options by sliding the switch at the top of the screen to Off.

• Test Drive Windows 7 Online with Virtual Labs

  - by Matthew Guay

  Did you miss out on the Windows 7 public beta and want to try it out before you actually make the leap and upgrade? Maybe you want to learn how to deploy new features in a business environment. Here’s how you can test drive Windows 7 directly from your browser. Whether you manage 10,000 desktops or simply manage your own laptop, it’s usually best to test out a new OS before installing it.  If you’re upgrading from Windows XP you may find many things unfamiliar.  Microsoft has setup a special Windows 7 Test Drive website with resources to help IT professionals test and deploy Windows 7 in their workplaces.  This is a great resource to try out Windows 7 from the comfort of your browser, and look at some of the new features without even installing it. Please note that the online version is not nearly as responsive as a full standard install of Windows 7.  It also does not run the full Aero interface or desktop effects, and may refresh slowly depending on your Internet connection.  So don’t judge Windows 7’s performance based on this virtual lab, but use it as a way to learn more about Windows 7 without installing it. Getting Started To test drive Windows 7, visit Microsoft’s Windows 7 Test Drive website (link below).  You will need to run the Windows 7 Test Drive in Internet Explorer, as it requires Active X support.  We received this error when attempting to run the Test Drive in Firefox: Now, click the “Take a Test Drive” link on the bottom left of the page. This site includes several test drives to demonstrate different features of Windows 7 and its related ecosystem of products including Windows Server 2008 R2, some of which, including the XP Mode test drive, are not yet ready.  For this test, we selected the MED-V Test drive, as this includes Office 2007 and 2010 so you can test them in Windows 7 as well.  Simply select the test drive you want, and click “Try it now!”   If you haven’t run a Windows test drive before, you will be asked to install an ActiveX control.  Click the link to install. Click the yellow bar at the top of the page in Internet Explorer, and select to Install the add-on.  You may have to approve a UAC prompt to finish the install. Once this is finished, click the link on the bottom of the page to return to your test drive.  The test drive page should automatically refresh; if it doesn’t, click refresh to reload it. Now the test drive will load the components.   Once its fully loaded, click the link to launch Windows 7 in a new window. You may see a prompt warning that the server may have been impersonated.  Simply click Yes to proceed. The test lab will give you some getting started directions; click Close Window when you’re ready to try out Windows 7. Here’s the default desktop in the Windows 7 test drive.  You can use it just like a normal Windows computer, but do note that it may function slowly depending on your internet connection.   This test drive includes both Office 2007 and Office 2010 Tech Preview, so you can try out both in Windows 7 as well. You can try out the new Windows 7 applications such as the reworked Paint with the Ribbon interface from Office. Or you can even test the newest version of Media Center, though it will warn you that it may not function good with the down-scaled graphics in the test drive.   Most importantly, you can try out the new features in Windows 7, such as Jumplists and even Aero Snap.  Once again, these features will not function the quickest, but it does let you test them out. While working with the Virtual Lab, there are different tasks it walks you through. You can also download a copy of the lab manual in PDF format to help you navigate through the various objectives. The test drive system is running Microsoft Forefront Security, the enterprise security solution from which Microsoft Security Essentials has adapted components from. Conclusion These virtual labs are great for tech students, or those of you who want to get a first-hand trial of the new features. Also, if you’re not sure on how to deploy something and want to practice in a virtual environment, these labs are quite valuable.While these labs are geared toward IT professionals, it’s a good way for anyone to try out Windows 7 features from the comfort of your current computer.

• SQL Developer at Oracle Open World 2012

  - by thatjeffsmith

  We have a lot going on in San Francisco this fall. One of the most personal exciting bits, for what will be my 4th or 5th Open World, is that this will be my FIRST as a member of Team Oracle. I’ve presented once before, but most years it was just me pressing flesh at the vendor booths. After 3-4 days of standing and talking, you’re ready to just go home and not do anything for a few weeks. This time I’ll have a chance to walk around and talk with our users and get a good idea of what’s working and what’s not. Of course it will be a great opportunity for you to find us and get to know your SQL Developer team! 3.4 miles across and back – thanks Ashley for signing me up for the run! This year is going to be a bit crazy. Work wise I’ll be presenting twice, working a booth, and proctoring several of our Hands-On Labs. The fun parts will be equally crazy though – running across the Bay Bridge (I don’t run), swimming the Bay (I don’t swim), having my wife fly out on Wednesday for the concert, and then our first WhiskyFest on Friday (I do drink whisky though.) But back to work – let’s talk about EVERYTHING you can expect from the SQL Developer team. Booth Hours We’ll have 2 ‘demo pods’ in the Exhibition Hall over at Moscone South. Look for the farm of Oracle booths, we’ll be there under the signs that say ‘SQL Developer.’ There will be several people on hand, mostly developers (yes, they still count as people), who can answer your questions or demo the latest features. Come by and say ‘Hi!’, and let us know what you like and what you think we can do better. Seriously. Monday 10AM – 6PM Tuesday 9:45AM – 6PM Wednesday 9:45AM – 4PM Presentations Stop by for an hour, pull up a chair, sit back and soak in all the SQL Developer goodness. You’ll only have to suffer my bad jokes for two of the presentations, so please at least try to come to the other ones. We’ll be talking about data modeling, migrations, source control, and new features in versions 3.1 and 3.2 of SQL Developer and SQL Developer Data Modeler. Day Time Event Monday 10:454:45 What’s New in SQL Developer Why Move to Oracle Application Express Listener Tueday 10:1511:455:00 Using Subversion in Oracle SQL Developer Data Modeler Oracle SQL Developer Tips & Tricks Database Design with Oracle SQL Developer Data Modeler Wednesday 11:453:30 Migrating Third-Party Databases and Applications to Oracle Exadata 11g Enterprise Options and Management Packs for Developers Hands On Labs (HOLs) The Hands On Labs allow you to come into a classroom environment, sit down at a computer, and run through some exercises. We’ll provide the hardware, software, and training materials. It’s self-paced, but we’ll have several helpers walking around to answer questions and chat up any SQL Developer or database topic that comes to mind. If your employer is sending you to Open World for all that great training, the HOLs are a great opportunity to capitalize on that. They are only 60 minutes each, so you don’t have to worry about burning out. And there’s no homework! Of course, if you do want to take the labs home with you, many are already available via the Developer Day Hands-On Database Applications Developer Lab. You will need your own computer for those, but we’ll take care of the rest. Wednesday PL/SQL Development and Unit Testing with Oracle SQL Developer 10:15 Performance Tuning with Oracle SQL Developer 11:45 Thursday The Soup to Nuts of Data Modeling with Oracle SQL Developer Data Modeler 11:15 Some Parting Advice Always wanted to meet your favorite Oracle authors, speakers, and thought-leaders? Don’t be shy, walk right up to them and introduce yourself. Normal social rules still apply, but at the conference everyone is open and up for meeting and talking with attendees. Just understand if there’s a line that you might only get a minute or two. It’s a LONG conference though, so you’ll have plenty of time to catch up with everyone. If you’re going to be around on Tuesday evening, head on over to the OTN Lounge from 4:30 to 6:30 and hang out for our Tweet Meet. That’s right, all the Oracle nerds on Twitter will be there in one place. Be sure to put your Twitter handle on your name tag so we know who you are!
