• cannot access new drive through nfs

  - by l.thee.a

  I am running nfs-kernel-server to access my files on my linux machine(ubuntu - /share). The disk I have been using is full. So I have added a new disk and mounted it to /share/data. My other pc mounts the /share folder to /mnt/nfs; but cannot see the contents of /mnt/nfs/data. I have tried adding /share/data to /etc/exports, but it did not help. What do I do? PS: I am looking for another solution than explicitly mounting /share/data on the second drive.

• SSISDB Analysis Script on Gist

  - by Davide Mauri

  I've created two simple, yet very useful, script to extract some useful data to quickly monitor SSIS packages execution in SQL Server 2012 and after.get-ssis-execution-status  get-ssis-data-pumped-rows  I've started to use gist since it comes very handy, for this "quick'n'dirty" scripts and snippets, and you can find the above scripts and others (hopefully the number will increase over time...I plan to use gist to store all the code snippet I used to store in a dedicated folder on my machine) there.Now, back to the aforementioned scripts. The first one ("get-ssis-execution-status") returns a list of all executed and executing packages along with latest successful and running executions (so that on can have an idea of the expected run time)error messageswarning messages related to duplicate rows found in lookupsthe second one ("get-ssis-data-pumped-rows") returns information on DataFlows status. Here there's something interesting, IMHO. Nothing exceptional, let it be clear, but nonetheless useful: the script extract information on destinations and row sent to destinations right from the messages produced by the DataFlow component. This helps to quickly understand how many rows as been sent and where...without having to increase the logging level.Enjoy! PSI haven't tested it with SQL Server 2014, but AFAIK they should work without problems. Of course any feedback on this is welcome.

• Instructor Insight: Dealing with Columns in Oracle JD Edwards Enterprise One Tools Release 9.1

  - by Breanne Cooley

  Oracle JD Edwards Enterprise One Tools Release  9.1 has many new features that will help end users be more efficient in their daily jobs. For example, hiding grid columns is now as easy as a left-mouse click. In earlier releases, users could click on the ‘Customize Grid’ link but still had to do several more clicks to hide or show a column . The following example shows how easy this new feature is to use. First, right-mouse click on the column you want to hide; for example the ‘Long Address’ column. The column is now hidden. Second, right-mouse over on any of the columns to show the ‘Unhide’ option. After you select ‘Unhide’, the hidden column is shown. You can then select the column to show, or unhide, the column. This new feature and others are covered in the JD Edwards EnterpriseOne System Administration Rel 9.x course, which has been updated to reflect the new release. Hope to see you in class! -Randy Richeson, Senior Principal Instructor, Oracle University

• Make GRUB automatically boot Ubuntu

  - by Matt Robertson

  I am running a dual-boot with Ubuntu (10.10) and Windows 7. Recently I edited my /boot/grub/grub.cfg file to only show one version of Ubuntu (as opposed to several kernel versions) and Windows, simply by commenting out all other menu entries. My question is if I can edit GRUB to just boot a specific entry automatically. I tried removing all other menu entries, but GRUB still showed the menu with only one entry. I've also considered just setting the timeout to either 0 or 1 second, as this would basically achieve the same thing. What is the best way to do this?

• Does an SMTP request contain host header information (or just the IP of the targeted SMTP server)?

  - by Olaf

  We are using an external commercial smtp server for our newsletters (sending them through .NET components), and they offer two smtp URLs - smtp.critsend.com and fast.critsend.com -, and the second one is reserved for sending singular emails, the first one for bulk. Using nslookup shows that both resolve to the same 4 IP addresses (fast.critsend.com being an Alias). Question: (how) is it possible for the smtp relay to distinguish between different names? Is there something in the headers that can be compared to host headers in http protocol (I didn't find any intelligible information for a non-sysadmins)? The reason I'm asking is because we would like to use one of the IPs in our newsletter script (which works) rather than a name (in order to save DNS requests), and we are wondering about potential problems.

• CheckMemoryAllocationGame Sample

  - by Michael B. McLaughlin

  Many times I’ve found myself wondering how much GC memory some operation allocates. This is primarily in the context of XNA games due to the desire to avoid generating garbage and thus triggering a GC collection. Many times I’ve written simple programs to check allocations. I did it again recently. It occurred to me that many XNA developers find themselves asking this question from time to time. So I cleaned up my sample and published it on my website. Feel free to download it and put it to use. It’s rather thoroughly commented. The location where you insert the code you wish to check is in the Update method found in Game1.cs. The default that I put in is a line of code that generates a new Guid using Guid.NewGuid (which, if you’re curious, does not create any heap allocations). Read all of the comments in the Update method (at the very least) to make sure that your code is measured properly. It’s important to make sure that you meaningfully reference any thing you create after the second call to get the memory or else (in Release configuration at least) you will likely get incorrect results. Anyway, it should make sense when you read the comments and if not, feel free to post a comment here or ask me on Twitter. You can find my utilities and code samples page here: http://www.bobtacoindustries.com/developers/utils/Default.aspx To download CheckMemoryAllocationGame’s source code directly: http://www.bobtacoindustries.com/developers/utils/CheckMemoryAllocationGame.zip (If you’re looking to do this outside of the context of an XNA game, the measurement code in the Update method can easily be adapted into, e.g., a C# Windows Console application. In the past I mostly did that, actually. But I didn’t feel like adding references to all the XNA assemblies this time and… anyway, if you want you can easily convert it to a console application. If there’s any demand for it, I’ll do it myself and update this post when I get a chance.)

• Remote Desktop fails after VPN connection.

  - by Samet Sorgut

  The remote computer is connected with Remote Desktop. When the remote computer is connected to VPN the Remote Destop freezes. It is not possible to connect to the remote computer again via Remote Desktop. What can be done to connect to this remote computer after it establishes a VPN connection? The only thing that comes to my mind is to install a second NIC and configure Remote Desktop to accept connection from this NIC while VPN is working from the other... What do you suggest?

• How to retrieve all MySQL settings?

  - by Max Kielland

  I have a configured MySQL server (MySQL 5.1.47-community) that works perfect. I installed a second server (MySQL 5.5.15-community) to see if the new version of MySQL would work with my application before upgrading. When I run the application against the new server it behaves different. When I run it against the old server (MySQL 5.1.47-community) everything works perfect. I remember that I set some parameters through the MySQL prompt to accept larger result set and some other stuff, now I can't remember what I did. So my question is: Is there a way to transfer all the MySQL settings from one server to another? Thanks.

• RGB to DVI adapter not working for Projector-to-PC

  - by user897052

  We have a wall-mounted projector (dell 4320) with VGA In and the other end of the cable is RGB. We have an RGB to DVI-I adapter (w/ DIP switches) inorder to plug the cable into a PC (video card has 1 VGA and 1 DVI-I port). We had no problems until recently, when the PCs hard drive crashed. After re-imaging the PC, the computer no longer "sees" the projector (the computer doesn't detect the projector as a second monitor anymore). The PC is an older Dell with an after-market video card and runs win XP. I also tried it on a new HP box (win 7), but had to add a DVI-I to DVI-D adapter. Any ideas?

• Confused about javascript module pattern implementation

  - by Damon

  I have a class written on a project I'm working on that I've been told is using the module pattern, but it's doing things a little differently than the examples I've seen. It basically takes this form: (function ($, document, window, undefined) { var module = { foo : bar, aMethod : function (arg) { className.bMethod(arg); }, bMethod : function (arg) { console.log('spoons'); } }; window.ajaxTable = ajaxTable; })(jQuery, document, window); I get what's going on here. But I'm not sure how this relates to most of the definitions I've seen of the module (or revealing?) module pattern. like this one from briancray var module = (function () { // private variables and functions var foo = 'bar'; // constructor var module = function () { }; // prototype module.prototype = { constructor: module, something: function () { } }; // return module return module; })(); var my_module = new module(); Is the first example basically like the second except everything is in the constructor? I'm just wrapping my head around patterns and the little things at the beginnings and endings always make me not sure what I should be doing.

• Backup those keys, citizen

  - by BuckWoody

  Periodically I back up the keys within my servers and databases, and when I do, I blog a reminder here. This should be part of your standard backup rotation – the keys should be backed up often enough to have at hand and again when they change. The first key you need to back up is the Service Master Key, which each Instance already has built-in. You do that with the BACKUP SERVICE MASTER KEY command, which you can read more about here. The second set of keys are the Database Master Keys, stored per database, if you’ve created one. You can back those up with the BACKUP MASTER KEY command, which you can read more about here. Finally, you can use the keys to create certificates and other keys – those should also be backed up. Read more about those here. Anyway, the important part here is the backup. Make sure you keep those keys safe! Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• OpenWrt Backfire 10.03 Frequently Becoming Unresponsive (Bridged Client)

  - by Christopher Parker

  I have a Linksys WRT54G version 2 that I've flashed with OpenWrt Backfire 10.03. It's acting as a bridged client using the wl.o driver to give me network access in my home office, which is in a far corner of my house in a position that would make it exceedingly difficult to fish network cabling in through the walls. I have three network-ready devices attached to the device that don't currently support WiFi, including a networked printer. Ever since I migrated from WhiteRussian, which was also set up as a bridged client, to Backfire, the device has been becoming unresponsive, as though the OS itself has crashed or frozen. The WLAN light becomes completely solid and the LAN lights stay mostly solid, blipping off and then back on again maybe once a second or so. They all blink more or less in unison. Is there some way I can diagnose why this is happening so I can fix it? Right now, the only way to fix it is to unplug the device and plug it back in.

• Restoring Box Sync (box.com) using physical media after OS reinstall

  - by sjrm

  I have my Box Folder on a different drive ( D: ) than my Operating System Drive ( C: ) I follow these instructions to set the local folder on the second drive. https://support.box.com/hc/en-us/articles/200852947-How-Can-I-Change-the-Default-Folder-Location-for-Box-Sync- I had to format and reinstall Windows 7, leaving the other drive (D: ) untouched. now i reinstalled Box Sync, and directed it to the same location where i already have all my files. However, Box Sync renamed the folder to (Box ([email protected]) ) as a bckup, and is downloading everything again. As i have like 30Gb of files, and it takes many hour to download them, i just want to use the files that i already have in my local disk. i tried copying all files again to the new local Box Folder, but files started to get duplicated. Is there any way to avoid downloading everything again each time i reinstall my OS ? Thanks

• Regular Expressions Cookbook Code Samples

  - by Jan Goyvaerts

  %COOKBOOKFRAME% One of the common criticisms against the first edition was that we didn’t have the regular expressions and code samples available for download. Since our book only has very short code snippets rather than complete programs, we (the authors) did not have these available as separate files either. But for the second edition we’re trying to do better. You can now download the code samples from the 2nd edition of Regular Expressions Cookbook. This HTML file contains all the blocks with regular expressions and source code from the book, along with the titles of the chapters, recipes, and sections that they are found in. If you have purchased the book, you can use this file to easily copy and paste the regular expressions and source code snippets. Even if you purchased the ebook, you may prefer to use this file. The regexes in the ebook are formatted with line breaks and gray dots for spaces to make them easier to read in print. The HTML file does not use such formatting, so you can copy and paste them directly. This means that some very regexes will run beyond the edge of your browser window.

• Are there videocamera which geotag individual frames?

  - by Grzegorz Adam Hankiewicz

  I'm looking for a way to record live video with the specific requirement of having each frame georeferenced with GPS. Right now I'm using a normal video camera with a PDA+GPS that records the position, but it's difficult to sync both of these plus sometimes I've forgotten to turn the PDA+GPS or it has failed for some reason and all my video has been useless. Using google I found that about two years ago a company named Seero produced such video cameras and software, but apparently the domain doesn't exist any more and I only find references of other pages mentioning it. Does somebody know of any other product? I need to record this video in HD and have some way to export to Google Maps or other GIS software the positions of the frames in a way that I can click on the map and see what was being recorded in the video at that point. The precission of the GPS tracking is good enough as one position per second, intermediate frames of the video stream can be interpolated.

• Boot problems w/ External HDD

  - by JeremyT

  I'm having a problem with booting a live image off of a USB Hard Drive. I used Startup Disk Creator to make an Ubuntu 11.10 live image on a partition on my external so that I can use it on various computers. I set it up with ~4GB of persistent data So far I've tried it on two computers. One, a Dell, will boot to my external but it loads the select boot device very slowly. It hangs on a screen with an underscore for up to 5 minutes until it allows me to select which drive I want to boot from. After that, it works great. However, on my primary computer it doesn't work at all. It's an Acer from 2009 and it won't even recognize the drive. I don't see it anywhere in BIOS or the select boot disk list. The light on the external will come on at boot just fine so I know it's powering it at this time. Both computers worked perfectly with my 4GB flash drive that I had partitioned half and half (1st half FAT32 and second Ubuntu 11.10 live)

• Windows 7 starter will not shutdown or logoff

  - by richzilla

  Hi all, Im having some problems with a friends netbook (a dell mini 10). It will not shutdown or logoff via the usual route. Whenever the shutdown/logoff button is clicked, it will briefly freeze (maybe for only a second) and then do nothing. Ive tried shutting down manually via the command line using shutdown /p but all to no avail, it just defaults back to flashing cursor in the command prompt. There doesnt seem to be any mention of a similar problem on google so i was wondering if anyone else had any ideas. Thanks oh and its runnning windows 7 starter.

• Ad-hoc String Manipulation With Visual Studio

  - by Liam McLennan

  Visual studio supports relatively advanced string manipulation via the ‘Quick Replace’ dialog. Today I had a requirement to modify some html, replacing line breaks with unordered list items. For example, I need to convert: Infrastructure<br/> Energy<br/> Industrial development<br/> Urban growth<br/> Water<br/> Food security<br/> to: <li>Infrastructure</li> <li>Energy</li> <li>Industrial development</li> <li>Urban growth</li> <li>Water</li> <li>Food security</li> This cannot be done with a simple search-and-replace but it can be done using the Quick Replace regular expression support. To use regular expressions expand ‘Find Options’, check ‘Use:’ and select ‘Regular Expressions’ Typically, Visual Studio regular expressions use a different syntax to every other regular expression engine. We need to use a capturing group to grab the text of each line so that it can be included in the replacement. The syntax for a capturing group is to replace the part of the expression to be captured with { and }. So my regular expression: {.*}\<br/\> means capture all the characters before <br/>. Note that < and > have to be escaped with \. In the replacement expression we can use \1 to insert the previously captured text. If the search expression had a second capturing group then its text would be available in \2 and so on. Visual Studio’s quick replace feature can be scoped to a selection, the current document, all open documents or every document in the current solution.

• Update to SQL Server Configuration Scripting Utility

  - by Bill Graziano

  Last spring I released a utility to script SQL Server configuration information on CodePlex.  I’ve been making small changes in this application as my needs have changed.  The application is a .NET 2.0 console application.  This utility serves two needs for me.  First it helps with disaster recovery.  All server level objects (logins, jobs, linked servers, audits) are scripted to a single file per object type.  This enables the scripts to be easily run against a DR server.  If these are checked into source control you can view the history of the script and find out what changed and when. The second goal is to capture what changed inside a database.  Objects inside a database (tables, stored procedures, views, etc.) are each scripted to their own file.  This makes it easier to track the changes to an object over time.  This does include permissions and role membership so you can capture security changes.  My assumption is that a database backup is the primary method of disaster recovery for databases so this utility is designed to capture changes to objects.  You can find the full list of changes from the original on the Downloads page on CodePlex.

• How do I install Ubuntu 13.10 from a partition on my Mac?

  - by Barry

  I am trying to install Ubuntu 13.10 on my Macbook Air. I've previously had no issue installing from a USB stick to this machine. However, I don't currently have access to a USB stick or any external media at all! What I've done so far is partitioned my SSD into 3 partitions. One holds OS X, another is a 5gb partition intended for the install ISO, and a third is intended to be the target for that install. The second two partitions are formatted as FAT. I've used dd (with and without bs=1m) to "burn" my ISO to the small 5gb FAT partition. I also at one point tried using hdituil to convert my ISO file to IMG and went through the same process with same result below. After "burning" my ISO to the small partition, I reboot into Refind. Refind sees my small 5gb partition perfectly well, and when I select that partition it loads GRUB appropriately. However, from here, regardless of what I choose, Ubuntu will start to load and then after a few minutes crash out to: BuzyBox V1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) Enter 'help' for a list of built in commands. (initramfs) unable to find a medium containing a live file system. I've Googled this error and found a number of people encountering it when trying to install from USB, but no solutions seem applicable to my case (installing from a partition on my SSD, to another partition on my SSD). Is there any solution to this, or do I just need to wait a few days until I have access to a USB stick? Many thanks in advance, and apologies for length -- I figured I'd err on the side of being exhaustive rather than having people suggest things I've already tried.

• Sharing a wifi connection between different user profiles on Windows XP

  - by crowne

  I've set-up two separate user profiles on an old laptop running Windows-XP, and noted the following strange behaviour. When the wireless network is setup using WEP both user profiles can connect to the internet and I can switch between user profiles, without network connectivity issues. However when I changed the wireless security to WPA2, the first user to connect gets access to the internet, when switching to the second profile the connection fails. The behaviour is the same regardless of which of the two profiles logs on first. I also tried this with one user with admin rights and one without, and got the same result. I'm not too concerned about a fix for this other than forcing the users to log-off when sharing the laptop, but I'd be interested to know if anyone can corroborate my findings. The network config was done using Intel® PROSet/Wireless.

• EPM Planning 11.1.2 - MassGridStatistics

  - by Keith Rosenthal

  A utility is available for Oracle Hyperion Planning that determines web form load times.  This utility, MassGridStatistics, opens all web forms within the Planning application.  After the forms are opened, an html page will appear showing the form options, suppression, number of row column and page members, and load times.  Any form having a load time longer than one second could potentially have scalability issues in a multi-user environment and should be considered for re-design.  Adding suppression (especially block suppression) and reducing the number of rows and columns are potential fixes that will reduce load times. The MassGridStatistics utility is located in a .7z file called MassGridStatistics.7z.  Extract the file using 7-Zip.  A readme file is provided listing the installation instructions and the steps to run the utility. MassGridStatistics is included with the 11.1.2.1.101 patch set and will also be in all future releases starting with 11.1.2.2.  For earlier Planning releases, an SR will be necessary to have Support provide the utility.
