  • What are the appropriate mount options for a shared NTFS partition on an SSD in a dual boot Ubuntu/Windows setup?

    - by Andreas Jonsson
    I have Ubuntu 13.10 and Windows 7 installed in dual boot on a single SSD. In addition they share an NTFS partition where I put all my data and documents. What is the optimal way to mount this NTFS partition in /etc/fstab (considering performance and minimizing wear of the SSD)? Similar questions have been asked, but I could not find answers to this particular scenario. As I understand it, the mount option 'discard' is not supported for NTFS and so should not be used (although it is recommended here). Another often quoted mount option is 'noatime'. I use it for my ext4 partitions. Does it apply to NTFS? My current /etc/fstab line is: UUID=XXXXXXXXXXXXXXXX /dos ntfs defaults,nls=utf8,uid=1000,gid=1000 0 0

  • How can i get latency when using Game Center?

    - by Freddy
    I'm pretty new to network programming. Basically I'm using game center for making a relatively simple iPhone game using Game-center p2p. However i'm now working on a algorithm to improve the multiplayer performance. But, I need to know how long it took for a package to travel from one device to the another device (latency) for the algorithm to work good. As for now, I have solved the problem by sending a double with time interval since 1970 in the package and then I compare it with the time at the other device. However I have heard that the NSDate methods is connected to the internet, which also will cause latency so the time interval would not be perfectly correct. What is the ideal way to check for how long it take for a package to be sent?

  • How does apt-btrfs-snapshot work?

    - by Oli
    I read on the planet that apt-btrfs-snapshot would be available for Natty. The brief description of what it does sounds very nice: it will automatically create filesystem snapshot (of everything but /home) when apt installs/removes/upgrades. With the apt-btrfs-snapshot cli app its easy to list/remove/rollback the snapshots But before I convert my entire life to btrfs for the sole purpose of gaining a built-in backup system, can anybody tell me how btrfs's snapshots work. To my layman's brain, it sounds like this would eat a devastating amount of disk space if you're taking snapshots every time you install or upgrade something (I do this more than once a day). I assume the system is smarter than I'm allowing it but I really don't know. How do the snapshots work?

  • Disable suspend / hibernate via the policykit

    - by redonath
    I am trying to run Lubuntu 12.04, but if the computer suspends I am unable to bootup again. Instead I see the bios post, the hard disk light flickers once and I have to install again (I have tried to re-install grub2). I am new to Linux and what I found that best answered my question was posted by James Henstridge. The instructions say to create disable-shutdown.pkla in etc/polkit-1/50-local.d/ but this directory does not exist, so do I create a folder titled 50-local.d in poolkit-1 or do I have to place this file elsewhere?

  • Can't Select Continue to install ubuntu alongside them

    - by msknapp
    I'm trying to install ubuntu 14.04 alongside Window 7 on my PC. I got to the installation type page and it detected my windows 7, then asked me what I would like to do. I selected the option to install ubuntu alongside them; however, the continue button was then grayed out. If instead I chose the option to do something else, the continue button was still grayed out. I was given absolutely no explanation for why it was grayed out. The only option that would let me continue was to erase the disk, which I do not want to do. I have two hard disks, and one of them has two partitions on it. The second partition is completely unused, and has a terabyte of space. That's where I wanted to install it. Can somebody please tell me why I can't install ubuntu alongside Windows 7 here?

  • Cheerp -- C++ for web: advance or regression?

    - by Henrique Barcelos
    Recently I've run into Cheerp, a C++ to Javascript compiler, which uses a modified version of clang to generate Javascript code from C++ sources. That makes me wonder: why in the seven kingdoms would someone do this in their right mind? I mean: why would you take a language that is not designed for web at all, that is far more convoluted and bureaucratic, write your code and then compile it into Javascript itself? Can anybody see any advantages in doing so? We surely can discard performance as a reason, because in the end it generates pure Javascript code. Is there anyone here that have real experience with this? P.S.: I'm not sure if this is an on topic question, but this is the most general forum about programming that I could find in the StackExchange network. Edit Although this seems like a subjective question, it is not. I am asking for reasons that this tool could be useful. I got interested at first, but started wondering why would someone use it.

  • mounting external hard drive EXT4: "the unlocked device does not have a reckognizable filesystem on it"?

    - by user824924
    I'm having problems mounting ext4 partitions(inside a LUKS partition) in external drives. The drives are fine, there is no problem whatsoever with the drives and no filesystem corruption. This happened since a recent automatic system upgrade, and a manual upgrade to kernel 3.12.0. It goes like this: I plug in the external drive Passphrase is asked for luks device luks partition correctly unlocked/opened Instead of proceding with mounting the now exposed ext4 partition there's a pop-up saying: "the unlocked device does not have a recognizable filesystem on it". Same happens in this case: $ gvfs-mount -d /dev/sdc2 Enter a passphrase to unlock the volume The passphrase is needed to access encrypted data on WDC WD250... (250 GB Hard Disk). Password: Error mounting /dev/sdc2: The unlocked device does not have a recognizable file system on it Doing a manual sudo mount /dev/dm-1 /mnt/testfolder works with no errors and there is no problem with the filesystem (fscked). Also there doesn’t seem to be anything useful written to dmesg when this happens. What gives?

  • Custom code in SharePoint

    - by Sahil Malik
    SharePoint 2010 Training: more information Microsoft launched SharePoint 2013 with great fanfare. But what stuck out was the introductory blog post by Corporate SVP of SharePoint, Jeff Teper. You can read the blogpost titled “The New SharePoint”. But one paragraph has stuck out, “Use SharePoint as an out-of-box application whenever possible - We designed the new SharePoint UI to be clean, simple and fast and work great out-of-box. We encourage you not to modify it which could add complexity, performance and upgradeability and to focus your energy on working with users and groups to understand how to use SharePoint to improve productivity and collaboration and identifying and promoting best practices in your organization.” The keywords here is “whenever possible”. The reality is, frequently it is not possible to not customize SharePoint in order to meet the customer requirements. But you must try and minimize SharePoint customization.

  • Xobni Plus for Outlook [Review]

    - by The Geek
    Overview Xobni Plus is an addin that will bring a sidebar to Outlook which allows you to search through your inbox and contacts a lot easier. It provides the ability to search and keep track of your favorite social networks. Searching with Xobni is a lot more powerful than the default search feature in Outlook. It let’s you drill down your searches to conversations, email, links, and attachments. It now supports Outlook 2010 both 32 & 64-bit versions. Installation & Setup Installation is easy following the wizard. After completing the wizard you can tell you’re friends on Facebook and Twitter that you are now using it. You can also decide to join their Product Improvement Program if you want. After installation when you open Outlook, Xobni appears as a sidebar on the right side. Don’t worry about it always being in the way, as you can hide it if you need more room for other Outlook functions. After Xobni free is installed, you can upgrade to the Plus version at any time. A new window will open up and you can use your Credit Card, PayPal, or redeem a code if you have one. Features & Use Where to begin with the amount of features available in Xobni Plus? It really has an amazing amount of cool features. Of course you’ll have all of the features of the Free Version which we previously covered…and a lot more. After Xobni is installed you’ll notice a section for it on the Ribbon. From here you can search Xobni, show or hide the Sidebar, and change other options. It allows you to easily keep up with various social networks like Facebook, Twitter, and LinkedIn… Check out email analytics and contact ranks. Click on the Files Exchanged tab to search for specific attachments. Quickly search links exchanged with your contacts. Hover over a link to get a preview of what it entails. It gives you the ability to index all of your Yahoo mail as well, without the need for purchasing Yahoo Plus! Then your Yahoo messages appear in the Xobni sidebar. When you select a contact you can see related messages from you Yahoo account. Easily index all of your mail…including Yahoo mail for better organization and faster search results. There are several options you can select to change the way Xobni works. From setting up your Yahoo email, Indexing options, and much more. Additional Features of Xobni Plus Advanced Search Capabilities – Filter results, Boolean & Phrase Search, Ability to search Appointments & Tasks, Advanced Search Builder Search unlimited PST data files Xobni contacts in the compose screen Find links exchanged with your contacts View calendar appointments One year premium tech support No Ads! Performance We ran Xobni Plus on Outlook 2010 32-bit on a Dual-Core AMD Athlon system with 4GB of RAM and found it to run quite smoothly. However, we did notice it would sometimes slow down launching Outlook, especially if other apps are running at the same time. Product Support When you buy a license for Xobni Plus you get a full year of premium tech support. They provide a Questions and Answers page on their site where you can run a search query and answers appear instantly. You can contact support directly as a Plus member through their web form and they advise the turn around time is 2 business days. However, when we tested it, we received a response within 24 hours. They also provide FAQ, Community forum, and you can download the Owners Manual in PDF format from the support page. Conclusion Xobni Plus is a very powerful addin for Outlook and includes a lot more features that we didn’t cover in this review. You can download Xobni free edition which includes an 8 day free trial of the Plus version. This provides a good way to start getting familiar with it. Then upgrade to Xobni Plus at any time for $29.95. Once you get started, you’ll find the sidebar is nicely laid out and intuitive to use. If you live out of Outlook during the day, Xobni Plus is a great addition for fast and powerful searches. It provides an easy way to keep all of your contacts and messages well organized and easy to find. Xobni Plus works with XP, Vista, and Windows 7 (32 & 64-bit editions) Outlook 2003, 2007 and both 32 & 64-bit editions of Outlook 2010.

  • What features of old computers helped you learn to be a better programmer?

    - by David Cary
    What features of old computers helped you learn to be a better programmer -- but don't seem to be available on new computers? I imagine that, while educational, you are really glad some features are gone, such as programs ran so slowly that I could almost see each pixel being plotted, so I got a visceral feel for the effect of various optimizations. I imagine other features you may be a little nostalgic for, such as I could turn on the computer, and write a short program that printed "Hello, World" on the printer, before ever "booting" a "disk". (I'm hoping that this is constructive enough to avoid the fate of the " What have we lost from computers 20 years ago ?" question).

  • A little SQL tip for C# developers

    - by MikeParks
    The other day at work I came across a handy little block of SQL code from Jeremiah Clark's blog. It's pretty simple logic but through the mind of a C# developer making some quick DB updates, seems to me that it's more likely to end up writing out the code in Solution 1 instead of Solution 2 below to solve the problem. Basically, I needed to check and see if a specific record existed in Table1. If it does exist, then update that record, otherwise insert a new record into Table1. Solution 1: IF EXISTS (SELECT * FROM Table1 WHERE Column1='SomeValue')     UPDATE Table1 SET (...) WHERE Column1='SomeValue' ELSE     INSERT INTO Table1 VALUES (...) Solution 2: UPDATE Table1 SET (...) WHERE Column1='SomeValue' IF @@ROWCOUNT=0     INSERT INTO Table1 VALUES (...)         As Jeremiah explains, they both accomplish the same thing but from a performance standpoint, Solution 2 is the better way to go (saved table/index scan). Just wanted to throw this small tip out there. Thanks! - Mike

  • Disable auto-mount for particular partitions on usb drives

    - by nealmcb
    I have a big USB disk with 3 partitions: one for backup and two other bootable ones for installing and testing new distros. I want the backup partition automounted on boot. But I don't want the two test partitions automounted. Despite my use of "noauto" in /etc/fstab, something (gnome?) seems to be mounting them when I plug the drive it. LABEL=mybook /srv/backup ext4 defaults 0 2 LABEL=mybook-root /media/mybook-root ext4 user,noauto 0 2 LABEL=mybook-spare /media/mybook-spare ext4 user,noauto 0 2 In previous Ubuntu distributions it seems that it was possible to configure gnome so it would avoid mounting particular partitions on removable drives like USB: gnome-mount --write-settings --mount-options noauto --device /dev/sda1 This is no longer available in Lucid (when did it go away?) Is there another way to do this now?

  • Coding style advice? [closed]

    - by user1064918
    I'm a newly grad. I've got a lot of complaints from my supervisor at work during code-review sessions with regard to my coding style (Surprise!). I don't know if it's just him being cranky or my style is really that annoying to read. I come from the low-level language world (assembly, mostly), so I've been taught to use bitwise ops and all the cool tricks to do math whenever possible. I also have the habits of doing some other things that've been regarded as "too excessively dense to read". So I'm hoping to get some feedback from any experienced programmers! :) Also how should I justify between code performance and readability? Thanks!!
