• What tasks should be explicitly mentioned in a job reference? [closed]

  - by Martin

  Glossary A job reference (see also the german version) is a letter from the (former) employer that states what the employee did, and how well he did it. There are oh so weird rules here on how to phrase stuff therein, but this is not what this question is about. Question I hope this can even be generally answered, but even if country/region specific, I think there is enough international know-how on this site to get useful answers for different regions. I was wondering how detailed the tasks a programmer / developer did should be spelled out in a job reference. (After all, they can be spelled out in all detail in a CV when applying for a new job.) So how much detail is usual for a job reference? Example Developed Windows applications in C++ or Developed Windows Desktop Applications using C++ with MS Visual Studio 2005 and MFC, utilising Boost 1.47 and specif library xyz, focusing on subsystem abc for numerical calculations of ... etc. What makes more sense?

• Screen problems

  - by Erick

  I struggled a lot in order to install Ubuntu because of a problem with the video drivers caused by when installing the driver and after turning it on it just appears a black screen, which worked for me was to use the terminal with sudo setpci -s 00:02.0 F4.B=0 and the screen starts, but after rebooting the changes won't remain and I have to run that command again. My question is: How can I make the changes permanent and not to be in need to execute that command always when I shut it down? Original Question in Spanish: Problemas con pantalla He batallado mucho al instalar ubuntu por el problema con el controlador de video ya que al instalarlo al encenderla aparece solo una pantalla negra lo que me funciono fue usar desde consola sudo setpci -s 00:02.0 F4.B=0 enciende la pantalla pero al reiniciarla los cambios no se quedan guardados y tengo que volver a ejecutar ese comando mi pregunta es ¿como hacerle para que los cambios queden igual y no tener que estar ejecutando eso siempre que la apago?

• History of open source software

  - by Victor Sorokin

  I've been always interested, out of the pure self-amusement, in the history of open software used today: who were the people which started it and what were the reasons to start what were design decisions at the start how software evolved over the time Specifically, I'm interested in following software: GCC X Linux kernel Java Of course, there is plenty of information in Internet to google for, but I thought it would be nice to have list of interesting resources at this site. I hope some of visitors of this site have similar interest and can share a link or two they found particularly amusing/interesting. To make this entry more question-like, here's straight question: what are the most interesting/amusing links about history of open source software?

• How to register properly to the most famous SEOs? [closed]

  - by Olivier Pons

  I know it may have been asked many times, but here's my question: I'm about to open my website which I'm more than proud of (I'll talk about its capabilities on my blog). Anyway I want it to be registered by all the most famous SEOs and to be fetched often because it may grow up quickly. I know that a lot of people may have already asked this question but nevertheless I didn't find something relevant to that. I just want to know where I should register on all major SEOs when I release a website. Maybe this is a wiki, but I didn't find anything helpful on the subject. Any advice welcome.

• What is the best Video Conference integrated solution for Us? [closed]

  - by Andrei B

  we are trying to integrate a simple Video Conferencing (open source) solution into our existing application which is written in C++ and it runs on Linux. I am currently looking at using Ekiga (formely known as GnomeMeeting) or Homer Conferencing (short: Homer). My plan is to "integrate" an existing Video Conferencing client into our existing software. Please give me recommendation on which 3rd party application or library to use to add video conferencing feature to our application. PS: Please don't close this question. I asked it on StackOverflow and it got closed, so where am I supposed to ask this question? If not here, then whats the point of asking lol.

• Open Source Web-based CMS for writing and managing API documentation

  - by netcoder

  This is a question that have somewhat been asked before (i.e.: How to manage an open source project's documentation). However, my question is a little different because: We're not developing open source software, but proprietary software The documentation has to be hand-written, because we do not want to publish the actual software API documentation, but only the public API documentation I do want developers and project managers to write the documentation collaboratively Obviously, wikis are a solution, but they're very generic. I'm looking for a more specialized tool for this job. I've looked around and found a few like Adobe Robohelp, SaaS solutions and such, but I'd like to know if any open source software exists for that purpose. Do you know any Open Source Web-based CMS for writing and managing API and software documentation?

• Wine pollutes "Open With" application list

  - by Yi Jiang

  The dialog box in question here is the one you get with the context menu option "open with other applications". Wine seems to have inserted more than a dozen or so entries for each application I install, which makes it a pain to find the correct application: What can I do to remove the duplicates? Update: Neither of the two solutions really work. The bug is interesting, but the symptoms does not match my problem (I'm not having problem with uninstalling applications, but rather the things that are inserted after installing them), and with the other one, all references to the Wine application are removed, which actually makes the problem worse (although it may be an acceptable solution if nothing else can be found). So this is still an open question; any takers?

• What is the best way to restrict adult content on 12.04 LTS

  - by Stephen Myall

  I bought my kids a PC and installed 12.04 (Unity) on it. The bottom line is, I want my children to use the computer unsupervised while I have confidence they cannot access anything inappropriate. What I have looked at: I was looking at Scrubit which allows me configure my wifi router but this solution would also affect my other PC and mobile devices. This is not feasible as I just want the solution to work on one PC. I also did some Google searches and came across Nanny (it seems to look the part). My experience of OSS is that the best solutions frequently never appear first on a Google search list so my question is very specific. I want to leverage your knowledge and experience to understand “What is the best way to restrict adult content on 12.04 LTS” as this is important to me. Please don't answer this question "try this or that", then give me some PPA, I am looking for knowledge and experience from someone in my situation. Thanks in advance

• How does the GPL static vs. dynamic linking rule apply to interpreted languages?

  - by ekolis

  In my understanding, the GPL prohibits static linking from non-GPL code to GPL code, but permits dynamic linking from non-GPL code to GPL code. So which is it when the code in question is not linked at all because the code is written in an interpreted language (e.g. Perl)? It would seem to be too easy to exploit the rule if it was considered dynamic linking, but on the other hand, it would also seem to be impossible to legally reference GPL code from non-GPL code if it was considered static! Compiled languages at least have a distinction between static and dynamic linking, but when all "linking" is just running scripts, it's impossible to tell what the intent is without an explicit license! Or is my understanding of this issue incorrect, rendering the question moot? I've also heard of a "classpath exception" which involves dynamic linking; is that not part of the GPL but instead something that can be added on to it, so dynamic linking is only allowed when the license includes this exception?

• How do you answer "Rate yourself" questions?

  - by Vinoth Kumar

  Hi , I have been frequently asked questions like "Rate yourself in java" It goes like interviewer : Rate yourself in java on the scale of 10 me: 9 interviewer : Rate yourself in J2EE me : 8 .... But really I just come up with arbitrary numbers. Sure I know Java well , but what does it mean to say "9 out of 10" . I think it is a very subjective question, that does not make sense overall. The problem is ,if I say 9 , If I am not able to answer any question , the interviewer might think , "this guy just said 9" . On the other hand If I said 6 , there is a good chance the interviewer might think "He rates himself this low...not good" How do you respond to such questions ?

• Is this the right strategy to convert an in-level order binary tree to a doubly linked list?

  - by Ankit Soni

  So I recently came across this question - Make a function that converts a in-level-order binary tree into a doubly linked list. Apparently, it's a common interview question. This is the strategy I had - Simply do a pre-order traversal of the tree, and instead of returning a node, return a list of nodes, in the order in which you traverse them. i.e return a list, and append the current node to the list at each point. For the base case, return the node itself when you are at a leaf. so you would say left = recursive_function(node.left) right = recursive_function(node.right) return(left.append(node.data)).append(right);` Is this the right approach?

• Gitosis on Mac OS X (Snow Leopard)

  - by Shyam

  Hi, I have a Snow Leopard box, where I have gitosis installed (Warning: noob alert), added a git user and I am able to remotely login to the machine with ssh. Locally, I can 'clone' my created repositories, as I can 'clone' the gitosis-admin too. Works perfect. I clone these using the 'git' user. git clone git@my-remote-machine:reponame.git remotely logged in, what doesn't work: git clone git@localhost:reponame.git However on that same remote machine where the repositories live, I can't clone from the localhost. It asks for a password, which wasn't created as far as I know. What am I doing wrong? Thank you for your replies!

• django fcgi - call a management command with subprocess.Popen

  - by user41855

  Hi, I'm using an app called django-chronograph. It has a code of line which works in my dev environment and does not work in production: p = subprocess.Popen(['python', get_manage_py(), 'run_job', str(self.pk)]) This line crashes in production with: unknown command run_job Whereas when I run directly from command line: manage.py run_job It works fine. Interestingly it worked once when we exchanged 'python' with 'usr/bin/python'. then we restarted the server once more and it was back to old behaviour. Thus it seems as we have a python path issue. I'm not the guy who is running the server, its my app that should run and it would be great to get some help here. Attention: I'm a total noob regarding server-administration.. server environment: NGINX with FCGI-Daemon FCGI in prefork-mode

• What should my "code sample" look like?

  - by thesunneversets

  I've just had quite a good phone interview (for a CakePHP-related position, not that it's especially important to the question). The interviewer seemed to be impressed with my resume and personality. At the end, though, he asked me to email him a code sample from my existing work project, "to check you're not secretly a terrible programmer, ha ha!" I'm not too worried that my code can't stand on its own two feet, but I'm very much an intermediate programmer rather than an expert. What obvious pitfalls should I make sure my code sample doesn't fall into, in case they rule me out on the spot? Secondly, and this is probably the harder part of the question to answer, what features in a code sample would be so impressive that they would instantly make you much more favourably inclined towards the programmer? All ideas or suggestions welcomed!

• Card deck and sparse matrix interview questions

  - by MrDatabase

  I just had a technical phone screen w/ a start-up. Here's the technical questions I was asked ... and my answers. What do think of these answers? Feel free to post better answers :-) Question 1: how would you represent a standard 52 card deck in (basically any language)? How would you shuffle the deck? Answer: use an array containing a "Card" struct or class. Each instance of card has some unique identifier... either it's position in the array or a unique integer member variable in the range [0, 51]. Shuffle the cards by traversing the array once from index zero to index 51. Randomly swap ith card with "another card" (I didn't remember how this shuffle algorithm works exactly). Watch out for using the same probability for each card... that's a gotcha in this algorithm. I mentioned the algorithm is from Programming Pearls. Question 2: how to represent a large sparse matrix? the matrix can be very large... like 1000x1000... but only a relatively small number (~20) of the entries are non-zero. Answer: condense the array into a list of the non-zero entries. for a given entry (i,j) in the array... "map" (i,j) to a single integer k... then use k as a key into a dictionary or hashtable. For the 1000x1000 sparse array map (i,j) to k using something like f(i, j) = i + j * 1001. 1001 is just one plus the maximum of all i and j. I didn't recall exactly how this mapping worked... but the interviewer got the idea (I think). Are these good answers? I'm wondering because after I finished the second question the interviewer said the dreaded "well that's all the questions I have for now." Cheers!

• How do I import my first sprites?

  - by steven_desu

  Continuing from this question (new question - now unrelated) So I have a thorough background in programming already (algorithms, math, logic, graphing problems, etc.) however I've never attempted to code a game before. In fact, I've never had anything more than minimal input from a user during the execution of a program. Generally input was given from a file or passed through console, all necessary functions were performed, then the program terminated with an output. I decided to try and get in on the world of game development. From several posts I've seen around gamedev.stackexchange.com XNA seems to be a favorite, and it was recommended to me when I asked where to start. I've downloaded and installed Visual Studio 2010 along with the XNA Framework and now I can't seem to get moving in the right direction. I started out looking on Google for "xna game studio tutorial", "xna game development beginners", "my first xna game", etc. I found lots of crap. The official "Introduction to Game Studio 4.0" gave me this (plus my own train of thought happily pasted on top thanks to MSPaint): http://tinypic.com/r/2w1sgvq/7 The "Get Additional Help" link (my best guess, since there was no "Continue" or "Next" link) lead me to this page: http://tinypic.com/r/2qa0dgx/7 I tried every page. The forum was the only thing that seemed helpful, however searching for "beginner", "newbie", "getting started", "first project", and similar on the forums turned up many threads with specific questions that are a bit above my level ("beginner to collision detection", for instance) Disappointed I returned to the XNA Game Studio home page. Surely their own website would have some introduction, tutorial, or at least a useful link to a community. EVERYTHING on their website was about coding Windows Phone 7.... Everything. http://tinypic.com/r/10eit8i/7 http://tinypic.com/r/120m9gl/7 Giving up on any official documentation after a while, I went back to Google. I managed to locate www.xnadevelopment.com. The website is built around XNA Game Studio 3.0, but how different can 3.0 be from 4.0?.... Apparently different enough. http://tinypic.com/r/5d8mk9/7 http://tinypic.com/r/25hflli/7 Figuring that this was the correct folder, I right-clicked.... http://tinypic.com/r/24o94yu/7 Hmm... maybe by "Add Content Reference" they mean "Add a reference to an existing file (content)"? Let's try it (after all- it's my only option) http://tinypic.com/r/2417eqt/7 At this point I gave up. I'm back. My original goal in my last question was to create a keyboard-navigable 3D world (no physics necessary, no logic or real game necessary). After my recent failures my goal has been revised. I want to display an image on the screen. Hopefully in time I'll be able to move it with the keyboard.

• Flash Webcam non responsive

  - by powerbuoy

  I've got the same problem as this gentleman: https://answers.launchpad.net/ubuntu/+source/flashplugin-nonfree/+question/176541 Where the webcam settings / access does not work at all / is completely unresponsive in Ubuntu 11.10. I've tried webcam access in Facebook, Google+, my own code + a number of tutorials/demos and none work. What happens is the settings dialogue is completely unresponsive. Clicking tabs or buttons does nothing. In the question linked to a suggested answer is to run Unity 2D. Unfortunately this does not work for me (the exact same thing happens). I've also tried Gnome 3 which also does not work. Note that it is only the webcam settings that don't work. YouTube videos and annoying banners work just fine. Does anyone know of a workaround for this (except going back to 11.04) or if they've fixed this in 12.04? - also, are any of you experiencing the same thing?

• Using C++11 for cross-platform Game Engine Development

  - by Samaursa

  Note: This is not a 'give your opinion' question about C++03 and C++11. Our game engine, written in C++03, is designed to be compiled on Windows, OSX and iOS. Linux support is planned for the (very) near future. Our experience is limited when it comes to consoles, which is why I am asking this question. Currently, we are debating whether switching to C++11 and using non-compatible features of the C++11 standard could pose a problem in the near future when we need to port our engine to any of the current gen consoles (perhaps the compilers supported by some console(s) do not support C++11 yet? We don't know...). So, game developers who have experience across multiple platforms and consoles, do you think we should stick to C++03 until the new generation of consoles arrive and most everybody has switched to C++11 standard (have they already?). Or are most consoles using/support compilers (VC++, GCC or variants?) that are already supporting C++11 features?

• Configure mounting timeout at boot

  - by René Pieters

  On remotely rebooting a 12.04 machine I found it hanging at the "unable to mount soandso: Skip, Manual Abort? " (That's pretty much how I remember the message) The machine was basically stopped there until I hooked up a keyboard and pressed "s". I can see the rationale for the question, but I'd really like to know where to configure it or turn it off altogether. A mandatory question like this makes sense in a desktop environment but for servers I'd like more flexibility. So where do I fiddle and tweak this?

• When should I use static variables with primitive types?

  - by Felipe Cypriano

  Recently I came across the question NSString: Why use static over literal? and in the comments arrived a new question. In Objective-C there some "special" types that are just maps to C primitives. Like the NSInteger. #if __LP64__ || (TARGET_OS_EMBEDDED && !TARGET_OS_IPHONE) || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64 typedef long NSInteger; #else typedef int NSInteger; #endif I know how to use the static keywords for objects but I don't understand the implications on C primitive types. When should I use a static NSInteger x instead of NSInteger x? What happens with the memory in both cases?

• What is the correct way to install ATI Catalyst Video Drivers in 12.04 LTS?

  - by Stephen Myall

  I am planning on doing a fresh install of 12.04 LTS next weekend (I am currently on Beta) and want to know what is the correct way to install ATI Catalyst Video Drivers in 12.04 LTS? I have been reviewing all the Q&A on AU and the reason for asking this specific question is that I maybe be missing some dependencies from my planned coding. In a previous AU question relating to 11.10 (here) NOT 12.04 the accepted response stated that this was a dependency. sudo apt-get install ia32-libs I was also receiving conflicting advice on other websites which put doubts on what the correct approach was.

• Recommended certification to join in a game development internship [on hold]

  - by Conrado Costa

  I'm Brazilian and I'll go to California in July 2014 to study for 1 year and I'm intending to get a winter internship in the game development industry. I'm a programmer since 2008 and I know C#, PHP, Java, Python and a bit of Perl. My question is: do you know any certified required (or helpful) to get a winter job as a game developer? I have no problem to learn new languages, I'm thinking to get a C or C++ certified because I'm not sure about which is the most used language, but before to start a study marathon to take a certification, I have to choose the language and the certification itself. Can you help me, and is that a valid question?

I'm recently designing my local gas station utility app for iphone and ipad. I have absolutely no clue of find a relevant database. For example, if I want to make an app for pizza ordering in the great Chicago area. How do I get info (price, menu, location, etc.) of those pizza stores scattered all over Chicago? Can any one light something for me? I appreciated your help. **If this question is not suitable here please tell me and I will delete this post. Thank you.
