• How much code should I be responsible for?

  - by Mick

  Through colleagues and exit interviews, I have heard that at my small company I am "responsible" for anywhere from 3-10 times more code than I would be at another job. I'm trying to look for some sort of fuzzy metric that I can use to compare my workload with others in my field. By "code responsibility", I don't mean "I'm the only one who knows area X of the code base" (though sadly, it's often true in a startup environment), but rather am referring to a number like "code_base_size/number_of_developers". Are there any resources I can use to help me more accurately measure my work load than just counting lines of code?

• Cant mount cryptswap1 ?

  - by Jordan March

  From the reading I've done, it seems it's having issues mounting the encrypted files. The guys here: could not mount /dev/mapper/cryptswap1 Seem to be suggesting how to fix it, but I am new to Linux and have NO idea how to do any of that. Can anyone walk me through how to edit that file? Or should I just reinstal? Is there a way to reinstall and keep my programs? I do have separate partitions for boot root home and swap Running Acer Aspire 5750 Intel Core i3 4gb ram Ubuntu 12.10 64bit

• 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).

• Open Grid Engine or Akka/Something more fault tolerant?

  - by Mike Lyons

  My use case is that I have a pipeline of independent, stand alone programs, that I want to execute in a certain order on specific pieces of data that our output from previous pipeline stages. The pipeline is entirely linear and doesn't do anything in terms of alternate paths through the pipe. I'm currently using SGE to do this and it works OK, however occasionally a job will overstep it's memory bounds, fail, and all jobs that require that output data will fail. The pipe needs to be restarted in that case, and it seems that whatever is providing the fault tolerance in akka might solve that for me?

• Be careful when Git suppresses bin Folders

  - by Marko Apfel

  Initial situation Often for Visual Studio projects the typical content of a .gitignore file contains this line bin or [B|b]in It is used to avoid that Git tries to track compile outputs as repository relevant data. Problem But keep in mind: this will also suppress bin folders of additional stuff like frameworks and toolsets. For instance Microsoft.SDKs contains a folder named Bin with a lot of programs Simian contains a folder named bin with the program themselves If you store such artifacts also in the repository - according to the principle of a “self containing project” – you could lost the content in the bin folder! Solution Till yet I don’t have a good idea. So I verify for each new added toolset or framework whether it has or has not such a bin folder. If it has, then I must add this bin folder manually to the repository so that Git track it.

• Is there a command-line utility app which can locate a specific block of lines in a text file?

  - by fred.bear

  The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :)

• Firefox really slows down my computer

  - by user199208

  I love Firefox; it has a special place in my heart. However, using the default Firefox in Ubuntu eventually causes my computer to freeze and crash. Nothing more to the problem, just the performance of Firefox really sucks, therefor causing a system-wide freeze. How do I know this? I use Google Chrome mostly, and other programs. None of them ever made my computer freeze. Is it an Update problem? If so, can I install a different version of Firefox from Mozilla.com? What's the deal here?

• No boot loader found - dual booting Windows 8 with Ubuntu 14.04

  - by Sriram

  I have been trying in vain to dual boot my computer with Windows 8 Pro (pre-installed) and Ubuntu 14.04 64-bit. I have been able to successfully install Ubuntu 14.04, but the option to start Ubuntu does not appear on startup. This is after having taken all steps as mentioned in Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported). I even tried the boot repair option and ended up with this error log. My questions are: How do I solve for No boot loaders found in /dev/...? Are there any other recommendations that will help me solve this? Other points that may be important: Booting into Ubuntu from a live USB shows all Ubuntu partitions on the hard drive.

• ".ts " files not recognised

  - by Keith Gardner

  I have some .ts files (programs recorded from my Sharp TV on USB stick) that I want to store/play on my PC. However, although they are listed on the stick when its plugged in the PC nothing will recognize the files. I have tried VLC (the "slider" moves but there's no sound or video) and changed the extension to MPEG, MP2, etc. but no joy. I have tried converting the files with file converters and demuxers but none of these recognize the files. Are the files corrupted (they play on the TV) or do Sharp have a unique file structure? Any help would be greatly appreciated.

• Unable to uninstall Wine apps

  - by CrunchyNeo

  I recently ran the iTunes 10 installer in Wine and everything seemed to go well. Then, when I tried to run it, it would constantly crash/and the appearance would be glitchy. After looking at the Wine website, it turns out that iTunes 10 has a 'garbage' rating of Wine compatability. Now I'm trying to remove/uninstall iTunes, QuickTime, and the other applications that come default with installing iTunes (such as Bonjour, etc.). However, when I run the 'uninstaller' that wine provides for the programs, it instead executes what appears to actually be the original installer! I've tried deleting all the configuration/data files in my Wine's file-system, but to no avail. Any help is greatly appreciated! Edit1: After re-running the uninstall process and then rebooting, the program (iTunes 10) still remained installed.

• Will mono be carried forward by upgrading to 12.04?

  - by vasa1

  I plan to upgrade from 11.10 to 12.04 when 12.04 is released. I noticed from my previous experience in upgrading from 11.04 to 11.10, that Synaptic, which was dropped in 11.10, was retained on my system presumably because I upgraded from 11.04 (which did have Synaptic by default) and didn't do a new install. Given that Synaptic was retained, my question relates to mono. According to the list here, I don't have any programs that need mono. (I've just purged Banshee.) If I don't remove mono, will it be carried forward when I upgrade to 12.04 just like Synaptic was? If the suggestion is to remove mono before the upgrade to 12.04, is sudo apt-get purge libmono* libgdiplus cli-common libglitz-glx1 libglitz1 still the recommended way to remove mono-associated material from 11.10?

• Does dist-upgrade require PPA software to be uninstalled first?

  - by seb

  Hi all, I'm still running Ubuntu 10.04 with quite a few PPAs. Amongst the PPAs there is Guiodic (Guido Iodice) Lucid quasi-rolling :) PPA which brings most recent versions of many programs to my desktop. My steps: sudo update-manager -d click on upgrade on the appearing window wait for the magic to happen: prepare to upgrade and setting new software channels during 'calculating the changes' I will get the following error message in the panel An error occurred, please run Package Manager form the right-click menu or apt-get in a terminal to see what is wrong. The error message was: ' Error: Marking the upgrade (E:Error, pkgProblemResolver::Resolver generated breaks, this may be caused by help packages.)'This usually means that your installed packages have unmet dependencies When I check Synaptic/apt-get I can't find any errors or hint toward broken packages Could this error be because of many PPA versions being newer than 10.04 original versions?

• What's shell script's advantage over interpreted programming languages?

  - by Lai Yu-Hsuan

  (I'm not sure if it's a appropriate question here) Shell script, like bash, can do many things. It can call Unix programs, pipe their output, redirect I/O from/to files, control flow, check whether a file exists, etc. But a modern programming language, e.g, python and ruby, can also do these all. And their are (I think) more readable and maintainable. bash is worldwide spreaded. But many distributions have installed python interpreter, too. So what's the advantage of shell script? If I could write python, ruby or perl, is it worth to learn bash?

• Icon zoom on gnome panel with mouseover?

  - by brent.with.a.mustache

  I'm actually quite surprised that I couldn't find any information regarding this question through simple google-ing; I would think that it was something of a no-brainer kind of question. I'm basically trying to figure out if there's any way to have the icons in the side panel/favorites bar magnify as you mouseover them, much like you'd see in any the popular launcher programs (i.e. rocket dock or apple's launcher)? I'm on a netbook with a rather limited amount of screen real estate to work with, so the icons depicting my "favorite applications" have been reduced to a permanent, unsatisfying handful of pixels. Again, it seems to me that this should be a fairly obvious feature to include in the options for the panel, so I'm hoping that there's an easy solution. Unfortunately, I haven't found any way to make this happen, so any help would be appreciated. Here's a screenshot :squint: http://i.imgur.com/OpMIF.jpg -- ubuntu 11.10; gnome 3; hp mini 110

• Thinkpad T530 with Optimus and Docking Station

  - by Vic Boudolf

  I have a Lenovo Thinkpad T530 with Optimus video, which is not supported on 12.04.1. I don't normally need the discrete (nVidia) graphics, so I turn it off in the BIOS settings to achieve longer battery life (and so that the screen dimmer will work), but when placed in the docking station, the integrated (Intel) graphics don't power the HDMI ports. (The VGA port does work, but I want to focus on the HDMI.) This means I have to change the BIOS settings constantly. Is there any way to have the system detect the docking station and power up/enable the discrete graphics accordingly? I don't need to do it on the fly. Just at startup. This post suggests that bumblebee can turn the discrete graphics on and off for specific applications, but I just want to turn it on or off. [2 suggests that vga_switcheroo will not work with nVidia Optimus.

• Common mistakes made by new programmers without CS backgrounds [on hold]

  - by mblinn

  I've noticed that there seems to be a class of mistakes that new programmers without CS backgrounds tend to make, that programmers with CS backgrounds tend not to. I'm not talking about not understanding source control, or how to design large programs, or a whole host of other things that both freshly minted CS graduates and non-CS graduates tend to not understand, I'm talking about basic mistakes that having a CS background will prevent a programmer from making. One obvious and well trod example is that folks who don't have a basic understanding of formal languages will often try to parse arbitrary HTML or XML using regular expressions, and possibly summon Cthulu in the process. Another fairly common one that I've seen is using common data structures in suboptimal ways like using a vector and a search function as if it were a hash map. What sorts of other things along these lines would you look out for when on-boarding a batch of newly minted, non-CS programmers.

• Problem with text deletion in vi editor

  - by user184256

  When I am writing C code on the vi editor, I am not able to use the backspace keys or my arrow keys to delete or navigate through lines. Some unexpected special characters occur on the screen that is on middle of my code and I am not able to delete them also. If I use my delete key, the whole code gets deleted. I have tried both insert mode using 'i' and 'a'. I am able to manage this situation for C programming by using the text editors but when I am creating LeX and yacc programs, I find this awkward. Can you please help me with this?

• Dual Boot Windows 8 UEFI and Ubuntu 12.10

  - by 0x4a6f4672

  I have got a new Samsung Series 7 laptop with Windows 8 where I tried to install Ubuntu. It is a 64-Bit system which uses UEFI and has "Secure Boot" switched on in the BIOS by default. After I switched if off (and set it to "UEFI and CSM OS") I was able to install Ubuntu (Ubuntu 11.10, which recognized Windows as Windows Vista, although it is Windows 8), by booting from CD with Settings/Change PC Settings/General/Advanced Startup in Windows 8. But after the installation and the restart of the machine somehow ignored Ubuntu and booted only Windows 8. Then I tried to reinstall Ubuntu 12.10. It still only boots Windows 8. Then I tried Boot Repair, which was not really helpful. Any ideas how I can create a dual boot system with Windows 8 and Ubuntu 12.10 ? Here is the link that Boot Repair generated: http://paste.ubuntu.com/1368624/ Is it necessary to create an extra EFI partition with GParted?

• How should I study programming languages?

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter).

• Best sites to find good .NET Developers

  - by Mag20

  I am looking for good sites to post a position for a .NET developer. I already tried: Craig's list got about 10 resumes, but most couldn't answer our technical questions StackOverflow Careers no responses What sites did you have success with finding good developers? UPDATE 1: Wanted to provide some more information: My company is in NJ. We are a small startup. Less then 10 people. Monster, Dice, CareerBuilder all charge like $500 a month per posting. Seems a bit much. Also only Dice is specifically targeting technical positions. With monster and career builder I am a bit worried about having to go through hundreds of resumes that don't apply.

• Question about Partitioning

  - by Trent C

  I am looking to dual boot Windows 7 and Ubuntu 13.10. I have been using windows for work and school for over a year, and have about 100 gig of stored files (backed up of course) and some paid programs. Because of this, I really want my partitioning experience to go well. Unfortunately, I am running into a bit of an anomoly When I load GPart, I see that my sda drive is unallocated http://i.imgur.com/Hi2XhIr.png Whereas my sdb appears to contain all of the windows files and partitions, and make up my C: drive http://i.imgur.com/aaCOXje.png Is this going to be an issue, as all literature on dual boot installation references sda?
