• Resized Ubuntu 14.04 partition will not boot

  - by user292577

  First, a little background info: I intended to install Ubuntu alongside OS X, but I accidentally erased my entire hard drive and was left with Ubuntu alone. Yesterday, I finally tried to create a desperate partition and OS X. I successfully shrank my Ubuntu partition and created ~40 GB of free space. I used gparted to do this. At first I tried to use Internet Recovery to install OS X on the unallocated space I had created, but discovered I couldn't. I went back to gparted and created a FAT partition with that space. I'm pretty sure I actually did this using my Ubuntu partition on my hard drive (the one I had just shrunken), rather than the USB live boot I had used to shrink it. Therefore, at this point, I think my Ubuntu partition was still functioning properly. I went back to internet recovery and used disk utility to turn the FAT partition into a Mac OS Extended (Journaled) [HFS/HFS+] partition. I believe this is probably where the problem occurred. I successfully reinstalled OS X and found it to be fully functioning. However, when I tried to boot back into the Ubuntu partition all I got was a black screen with a little white cursor (it looks similar to a terminal screen/the Mac DFU mode, but I can't type anything into it. Is there anything I can do to repair my Ubuntu partition? If not, can I at least recover the data from it? Thank you for any help.

• Is Clonezilla a good option for a daily batch-file-based backup of a Windows XP PC?

  - by rossmcm

  Having just been through the process of rebuilding a Windows XP desktop machine when the disk died, I'm anxious to make it a lot less painful. I didn't lose any data, but reinstalling everything took ages. Clonezilla seems to be a highly mentioned free backup tool. How easy would it be to implement the following: a nightly unattended backup of the desktop's disk image to another network machine (or a second drive in the machine), hopefully with compression. restore from that image using USB boot media. so that if I come in to work and find the hard drive has tanked, it is just a matter of replacing the dead drive with a new one, booting from the USB stick, choosing the image to restore, and then finding something else to do for an hour or two. When it is finished I would hopefully be back to where I was.

• Is the iPad in Europe totally unblocked?

  - by Mike

  One fast question: if I buy an iPad 3G in Europe will it work on other places without jailbreak? I ask this because I heard that, in Europe, iPads are not blocked to any telecom but I am not sure about that. On the other hand I am afraid do buy because I know that their cousins, iphones, are blocked to a specific telecom. Another question is regarding activation. As far as I remembered, my iPhone required me to do an activation step on iTunes and I remember it was also activated (or whatever) on the store (I remembered the salesman connected it to a computer and did some stuff before giving me the device). Is the iPad in europe totally free of operator? totally unblocked? thanks.

• Reducing storage cost by moving old files to external USB HDDs. Your thoughts?

  - by cparker4486

  I've got about 300GB of pictures and marketing data that is rarely accessed and I'd like to get it off my main storage. I was thinking to simply add two external USB HDDs to the server and move all the files to one of the drives. The second drive would be the backup destination for the first drive. I'm working with Server 2003 R2 SP2. This will help me free a good amount of space on my main storage as well as reduce the complexity, backup window, and usage of my backups to tape.

• How do I start a cloud9 service

  - by Lord Loh.

  Cloud9 is a free IDE available from https://github.com/ajaxorg/cloud9/ under GPLv3. I would like to use this to set up a service like https://c9.io/. The Cloud9 documentations do not mention anything about it. The Cloud9 documentation assume a sing user on localhost or bind to another address without one hard set username and hard set password. How do I run cloud9 IDE on my computer allowing multiple users? Are there any documentations? This is the closest to what I found - https://github.com/avgp/cloud9hub (for multiple workspaces)

• Sudden complaint that Windows is not genuine - some questions

  - by blade

  Hi, I used to use VMWare Workstation and made several VMs with Win Server 2008, which worked fine. My first tasks were to setup RDP, updates, and activate the OS. I deleted Workstation and thus did not have my VMs available to use for about 2 months. Now I have VMWare Server 2.0.2 as I this is free and I am going to get Hyper-V on a host Win Server in about March, but when I have accessed one of my VMs (haven't tried the others yet), it complains that the copy of Windows is not genuine. I now have a black screen but can access all my apps on the VM. Will the OS eventually shut me out from accessing it? I got my key from the Action Pack but the standard R2 key has been taken down and replaced with the Enteprise R2 key. I have Enterprise R2 but apparently the autorun is corrupt! Thanks

• BSOD During Windows 7 Install

  - by matheeeny

  I current have a working XP partition a Dell XPS m1330 laptop along with a working Ubuntu partition. After launching the Windows 7 install DVD from within XP I run through the options for a custom install on a free NTFS partition. Everything seemingly works as it should and then my computer restarts. After choosing to boot into the newly created Windows partition I am given the Windows 7 splash screen only to be followed by the BSOD. Here are the stop codes from the BSOD: stop: 0x0000007b (0x80D86B58,0xc0000034,0x00000000,0x0000000) Googling this tells me that it indicates an 'inaccessable boot drive'. Is it possible that its having problems booting from this partition due to the other existing partitions? I'm thinking that there may be a windows recovery CD workaround this but I am not quite proficient in its capabilities. This is what happens when I try to install by booting from the DVD

• Backup windows image to thumb drive?

  - by Dean

  I recently bought a new netbook from Malasia. It doesn't have a brand name, or officially supporting drivers. It came with a version of windows, and working drivers for all the hardware - but I want to install Ubuntu on here. Being a netbook, it has no CD/DVD drive. I want some free easy to use software to image the entire drive onto a thumb drive, which I could later use to boot up a recovery program to reinstall windows, should I fail to get all the hardware supported on Linux. I have already done some research and found driver backup/restore software in this thread, and will probably use that failing a more all-encompasing solution.

• Hosing website on own server. What is Hardware requirement and Cost [closed]

  - by KuKu

  As i am about to finish my dream website, i need to host it on some server. I checked Amazon AWS Free Tier, i found it pretty complex. As i made full website in java(JSP + Servlet + mysql + Node.js), its been expensive to host. So i thought that why not to host on own server so that i will be fully dependent on my resources, not on any one else. And i know, in future i need to pay more and more to the other hosting company(because of uploading images and number of incoming users). So my question is, On initial stage what kind of hardware i will required. What can be the cost of that hardware? I already have 12MBPS broadband connection, will it be sufficient? It has static IP Address as well.

• VPN server on Windows Server 2008 for a small office

  - by cmbrnt

  I'm going to refurbish the IT-infrastructure for a small organization with one single office, and I'm not sure what VPN server to use. In your opinion, would the built-in Windows Server 2008 VPN server suffice or are there any specific problems with it as opposed to, for example, OpenVPN? I'd rather run a Windows native VPN server, but if there are few (preferably free) good alternatives, I could install VMware ESXi and virtualize both Windows and an OpenVPN-server. By the way, because of a low budget this office runs a solution with only one physical server. Any advice would be great to help me grasp this field of which I'm quite a novice. Thank you!

• Dependency injection: At what point am I allowed to create a new object?

  - by Gaz_Edge

  I am refactoring a PHP application, and I am trying to do has much dependency injection (DI) as possible. I feel like I've got a good grasp of how it works, and I can certainly see my classes becoming a lot leaner and more robust. I'm refactoring so that I can inject a dependency rather than create a new object within the class, but at some point I am going to have to create some objects, that is, use the dreaded new keyword. The problem I have now run into is at what point can I actually create new objects? It's looking like I'll end up at a top level class, creating loads of new objects as there is no where else to go. This feels wrong. I've read some blogs that use factory classes to create all the objects, and then you inject the factory into other classes. You can then call the factory methods, and the factory creates the new object for you. My concern with doing this is now my factory classes are going to be a new free-for-all! I guess this may be OK as they are factory classes, but are there some rules to stick to when using a factory pattern and DI, or am I going way off the mark here?

• Remove MySQL ibdata1 without dumping and restoring existing proper databases

  - by Halfgaar

  My MySQL server contains two 100+ GB big databases. One was created with innodb_file_per_table and one wasn't. The one that wasn't, has been dumped, ready to be reloaded. However, the ibdata1 file is still huge and I don't have enough free space. Normal advice in this situation is to dump and remove each database, stop MySQL, then remove ibdata1 and the transaction logs, and then reload the databases. My specific question is: can I leave databases that were created with innodb_file_per_table alone? Or will they be destroyed when I remove ibdata1, even though all their files are separate? I can't afford to take this database off-line to dump and reload it. And because it's already properly made with separate files per table, it would feel pretty useless.

• What iPhone apps have I already purchased?

  - by torbengb

  I've bought many iPhone apps by now, some free and some paid. I've reinstalled my computer, and in the new installation, iTunes is completely blank. On first sync, iTunes downloads the apps that are currently installed on my iPhone. But what about all those apps that I have bought and aren't currently installed? Is there a way to re-download all my apps into iTunes? Where can I see a listing of all the apps I've ever downloaded? (Update: Apparently not all purchased content is restored - some things are inexplicably missing. You won't be charged anew for downloading them again, but you also won't be told what it is that you're missing. See here for details...)

• Java or Python? Career/Start-up advice needed [closed]

  - by vim

  I have a full-time PHP job and I've been working with PHP for 5 years. As you can guess after spending 5 years I'm not willing to stay within this technology stack any more. I also worked with Java for 2 year before, so for me it looks more obvious to switch back to Java. However during last 5 years I was thinking about starting my own project, and now I think I have a very good SAAS idea. I'm completely confused what technology should I use for my project. I don't want to do it in PHP, and after reading many articles about rapid prototype development it seems to me that Django/Ruby is the best option. I will continue to work full time for my current employer because I need to pay my bills and will work on my project in my free time. The concern I have is should I do my project in Java or Python? To be realistic there is always a risk when you are doing your own project/start-up. If I do it in Java in the worst case scenario I believe I will be able to find a full time Java position because I already have some experience in Java + recent experience in my project. With regards to Python it looks like it is not very popular in my area and salaries are much more lower then for Java. On the other hand I have a feeling that if I chose Java it will take me a way longer to finish my project. Guys I'm completely confused and I need your advice. P.S. I have moved to London 2 years ago from another country, local guys are very welcome to share their thoughts about London's job market.

• Game programming : C# or C++?

  - by Chronix

  Ok so the faq says : "What language should I learn next? (Unless you have a specific requirement and don't know which language meets that requirement.)" so I guess this is not against the rules of questions. So, I've decided what I really want is to do Game Programming. So the question is, as a 18 years old who wants to learn self taught programming, what is the most suited programming language between C# and C++? ( I should state that I don't care about unix because I believe windows will be still the most used os ) I know the basics of C++, but none about C#. I know that C++ has more tutorials guides, dlls and stuff like that, while C# doesn't, but it's far easier to learn and to use for a single person to develop a program, but I've read even if the program is obfuscated it's easy to get the source of it. Well, I kinda want to focus on basic a lot first, I must say that I have a preference for C++ just because it feels more suitable to me, but I must consider that I work alone.. So even if I like it, it may not be the best thing to do. I am really not sure of which one to go for, i've read a lot of threads on various websites and it looks like C# is becoming more popular than C++. But yeah, that said, I also specified I want to do Game Programming. So I need to know some better points than just "C# is easier because of .net memory handling while C++ isnt" because I couldn't just find it. I hope the thread won't be closed because I've read the faq and I have a specific requirement. Thank you, and if you need more details you're free to ask me, but I think just by saying game programming and that I'd work alone should be enough!

• A quick tip for those working with the Windows Phone 7 AD SDK.

  - by mbcrump

  One thing that I’ve noticed in several apps in the Windows Phone 7 marketplace is the ad chopping off on the right hand side. I decided that my next Windows Phone 7 app will be ad supported so why not sign up for the Advertising SDK and investigate this issue. *Note: If you want to see this in an actual app then download the free app called “Road Rage”. So here is an example of what I am talking about: You will notice that the right hand side of the AD is chopped off using the default ad banner. You can see the border on the left hand side clearly. So, what exactly is going on? Let’s take a look at this in the designer. From this image we can see it clearer, the margin of the grid that the ad is contained in needs to be removed. By default, the ContentPanel in a Windows Phone Page has a margin already set on it. See below for an example of this: <!--ContentPanel - place additional content here--> <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"> </Grid> If you simply remove that margin then your ad will display properly as shown below. It’s strange that I’ve seen this in multiple WP7 applications in the marketplace. If you are trying to make money off Ads, you would probably want to make sure the full ad is displayed. I am hoping this short post helped someone.   Subscribe to my feed

• XDMCP is slow any ideas? (looking for alternative remote desktops)

  - by peteri

  I've been used to using RDP on Windows to remote to machines, and I've got an asus eee 701 which I want to use to do some *nix programming on. While the eee is a lovely little machine the screen and keyboard are a little small to use for lots of programming. I've tried using Xming (the free version) to remote login into the eee from my desktop using XDMCP (or even using a ssh session as a straight X11 server and no desktop on the eee) the whole thing seems seriously slow over wifi the initial desktop takes at least 5 seconds to paint (might even be 10 seconds I haven't actually timed it). So my real question is what do other folks use for remote control with a GUI for their *nix boxes? I am finding it hard to believe the performance is so bad over a wifi network (It makes the Mac IIs I used to use a college in 1988 seem fast) or is this just a problem with Xming and using say the Cygwin X11 server would be better.

• Value my C++ knowledge

  - by PirateOwh

  I have only followed antiRTFM tutorials and read 2 books So, I'll list the things I know better : basic input output and all the variables : integers ( signed unsigned ), float, double, char arrays if, for, while, switch functions, and passing variables to functions and return type thing classes and the concept of oop with separating declaration and definition in the header and in the source pointers so this and some more i think is all i know of C++.. But, i need some exercises to test my knowledge because i want to move on to the library SDL, so I don't know if i should feel ready or not to move on to something totally different.. I feel I should know the basics for good at least. So the question is : How can i value my c++ knowledge? Is there any online tests? Is there any GDD ( Game Design Document ) for free to use and see if i can manage to do it so "i'd pass" ? ( I'm saying GDD since ill move on to SDL and try to make my own game ) When should I move to SDL? What are ALL the things I should "master" ( master is a big word to say.. but so you understand what i mean ) before moving on ? Please I'm really in need of expert advice. I think my question is detailed so i hope you understand what i mean and can give me a good reply. Thanks for the help!

• How does dropbox version/upload large files?

  - by barfoon

  Hey everyone, I have a free dropbox account (2GB), and I was wondering how the versioning of large files works. I have a full backup of all my webfiles that sites @ just over 1GB. After the initial upload of 1GB, everytime it syncs will dropbox figure out the delta of the file, or will it have to upload the entire thing again to version it? It would be cool to always have an up to date version of a large file, but I dont want to kill my bandwidth uploading 1GB everytime. Is this possible? Thanks,

They installed the Cisco VPN client and game an account for that. I think at this point I need some remote desktop software to login to my work Machine.

I have my work computer's name, and was hoping that would be enough to login, but I think I am mising a piece of the puzzle. Any thoughts on how to login to my work computer? Thanks.

• Customer Highlight: NTT DOCOMO

  - by jeckels

  NTT DOCOMO is the largest mobile operator in Japan, and serves over 13 million smartphone customers. Due to their growing data processing and scalability needs, they turned to Oracle's Cloud Application Foundation products for an integral soultion. At Oracle OpenWorld 2012, we first showcased NTT DOCOMO as a customer who was utilizing Oracle Coherence to process mobile data at a rate of 700,000 events per second (and then using Hadoop for distributed processing of big data). Overall, this Led to a 50% cost reduction due to the ultra-high velocity traffic processing of their customers' events. Recently, on October 7th, 2013, Oracle and NTT DOCOMO were proud to again announce a partnership around another key component of Oracle CAF: WebLogic Server. WebLogic was recently deployed as the application platform of choice to run DOCOMO's mission-critical data system ALADIN, which connects nationwide shops and information centers. ALADIN, which also utilizes Oracle Database and Oracle Tuxedo, is based on Java Platform, Enterprise Edition (Java EE), which has allowed the company to operate smoothly while minimizing additional development and modification associated with the migration of application server products. We look forward to continuing to partner with NTT DOCOMO, and are proud that Oracle Cloud Application Foundation products are providing the mission-critical solutions - at scale - that DOCOMO requires.

• What's a good box to serve files on my local network, cross platform?

  - by rogpeppe

  I've installed CAT5e cable and gigabit switches in my house with the goal of having an "always-on" file server in the loft, accessible to both my macbook and my partner's Windows box. I'd like to find a solution which: uses minimal power. allows me to access as much disk bandwidth as possible. provides glitch-free file access to both MacOS and Windows. is as cheap as possible, while remaining reliable. Optional, but desirable extras: software or hardware RAID; open source solutions. A SheevaPlug with eSATA seems one possibility, but I'm sure there are any number of other good options.

• Hard disk failure. Can I recover my "move"d folders?

  - by Doug

  I am in the process of moving all my files from an old laptop to new one. I just moved 11gb of data from my old laptop to a hard drive (external) and then upon moving it out to the new hard drive, the hard drive is getting a CRC (Data Error (Cyclic Redundancy Check). Now I am looking for a solution to recover the files that I moved on my old laptop (not the external). I understand they they are just marked for potential overwriting to free up space. I was getting ready to test out GetDataBack, but it says to install it on a healthy windows and use the recover-needed drive as an external. However, I don't want to turn off my computer without first getting the okay since it is in a "moved" state. Please help! What can I do to recover the Moved files. I haven't touched the computer since it has been moved. What can I use to recover them?

• Smart Phones Shockingly Energy Efficient; Lead to Decreased Household Power Consumption

  - by Jason Fitzpatrick

  Given how often our smart phones and tablets spend plugged in and topping off their battery reserves, it’s easy to assume they’re sucking down a lot of power. Analysis shows the lilliputian but powerful devices are surprisingly efficient and may be decreasing our overall power consumption. Courtesy of energy-centric blog Outlier, we’re treated to a look at the power sipping habits of popular smart phones and mobile devices. The simple take away? They use shockingly little electricity over the course of the year–you can charge your new iPhone for a year of regular usage for under a buck. The more complex analysis? The proliferation of tiny and energy efficient devices is displacing heavier energy consumers (large televisions, desktop computers, etc.) and driving a more efficient gadget-to-consumption ratio is many households.
