• Non-language-specific interview questions for a senior web developer

  - by Songo

  I came across a job posting for a senior web developer position. The posting said that the development will be done using Ruby on Rails, but no prior knowledge is required. I confirmed with a contact in that company that a PHP web developer can apply for it or even an ASP.Net developer. I also confirmed that the interview won't contain any questions specific to PHP or Ruby on Rails. Can anyone please provide a good list of questions for a senior web developer that isn't specific to a certain language? Note This question isn't a duplicate for similar posts asking for questions relating to PHP, .Net or Ruby. Also, I'm not looking for topics to learn as a web developer, but rather interesting questions for a technical interview given the former conditions.

• How much should I rely on Visual Studio's Auto Generated Code?

  - by Ant

  So I'm reading up on ASP.NET with VB.NET and I want to start making my own, professionally built website using ASP. I'm wondering though; I'm still using the basics so I'm really just a novice, but how much should I rely on Visual Studio to create my elements? Should I make my own text boxes and have my own login routine, or should I just use ASP's login features? I know eventually you have to use your own classes and such which is where the real coding comes in, but I'm not sure how relaible, flexible and secure the pre-wrote elements are? Any help would be greatly appreciated.

• Applying for job: how to showcase work done for (private) past clients?

  - by user33445566

  I want to apply for my first "real" (read: non-freelance) Ruby on Rails job. I've built several apps already. My best work (also the most logically complicated app) was for a freelance client, and I'd like to show it to potential employers. Only problem is: it isn't online anymore. And I've lost touch with the client. How can I include this work in my portfolio? About the app: It's a Facebook game. The client's business idea for this app was not the best. It was never going to make any money. I think it was kind of a vanity side project for him. The logo and graphics are nice-looking, though, and were designed by the client. I've actually spent a lot of time recently recoding most of the app, and adding a full test suite. I want to showcase the BDD / TDD skills I've acquired. I'm not very familiar with the etiquette (/law?) concerning this situation. Can I just put my new version of the app up at a free Heroku URL (perhaps with a "credits" section, where I credit the ideas and graphic designs to my former client)? NOTE: Again, this is just to show potential employers. I am not trying to market the app as my idea, or attract any users. Can I put some or all of the code on GitHub? What if I don't put the code up publicly, but merely send a tarball to potential employers? Do I need to ask permission from my former client (and what if he says no)? The last thing I want to do is get in any legal trouble, or offend people I'm trying get a job from. But I believe that my work and experience on this app are my highest recommendation for getting a job.

• Should I pass an object into a constructor, or instantiate in class?

  - by Prisoner

  Consider these two examples: Passing an object to a constructor class ExampleA { private $config; public function __construct($config) { $this->config = $config; } } $config = new Config; $exampleA = new ExampleA($config); Instantiating a class class ExampleB { private $config; public function __construct() { $this->config = new Config; } } $exampleA = new ExampleA(); Which is the correct way to handle adding an object as a property? When should I use one over the other? Does unit testing affect what I should use?

• Recommended online training sites on software development

  - by liortal

  I am looking for an online training site that provides courses on software development topics. Subjects that are needed for my work are .NET, general object oriented principles, design patterns, unit testing, continuous integration but not limited to these in particular. I have tried to use Pluralsight which was nice, however i am not sure the style of videos only is sufficient (for my at least). Are there any other training companies that provide online courses in other formats that you found useful (regarding .NET but not limited only to it). Thanks

• so disappointed at ubuntu 12.04 [closed]

  - by Min

  it's been almost a month I've installed ubuntu I can't afford windows cd anymore it is my fault that I didn't dual boot it but, it doesn't make sense in that I can't use my own graphic card in my own computer because certain company doesn't support the driver card for the OS it is seemingly ridiculous that I can't even run a simple 2d game or not even a flash game with this OS a video of 480 and up doesn't run for closely a month I've tried my best to run everything my computer spec provides, but nothing works. not even sound quality

• What music player for Ubuntu is *most* like Cog?

  - by mattshepherd

  Cog is, far and away, my favourite music player. File browser on the left panel, pull a folder into the right panel, it plays the files you pull into the main box. Simple! Easy! Nice! Especially since I store all my music on my non-primary drive. Cog doesn't care where I keep my music! It just deals with whatever folder I tell it to monitor. I also have about 200 gigs of music. It's a problem, I know. I can't find a player this simple and elegant in Ubuntu. Amarok: doesn't handle non-primary drives very well. Banshee: kinda good, but fussy browsing/playlist systems. Audacious: no file browser; it also crashes whenever I try to "import" all my music. All I want -- seriously -- is something where I can look at my MP3 folder, drag a folder onto a playlist, and have that playlist play the songs.

• apache2 server returns (400) syntax error

  - by Thomas E

  There are 900 paths in the googles index to our homepage containing illegal characters. Example: http://www.seriesam.com/filmaffisch/TC%4NK Note the character "%4N". I have no idea where they come from, but would like to update google index with a correct URL using "canonical" in the html code. But the problem is our apache2 server immediately sends a 400 error if you click the link above. How can I configure apache2 not to give an error code, but instead treat the link above as "correct"? Maybe replacing the char %4N with nothing.

• Upgrade failed, now impossible to restart

  - by Jean Claude Dispaux

  I have an Aspire One with Ubuntu, that I use only when traveling, i.e. seldom. Yesterday I tried to start it, it informed me that I had to install a new release of Ubuntu. The download went fine, then I left it for the night. In the morning I found error messages. I tried to restart, but nothing works any longer. The only backup I have is two USB keys made by the person who installed Ubuntu, that say Recovery Ubuntu 8 and Ubuntu 9.10 respectively. Right now I plugged the "8", selected F12 and instructed to boot from the USB key. It has been running for an hour, the screen still says ubuntu, the USB key flashes red. By the way, I have no precious data on this machine, I do not care about losing data. Please advise on what to do now. Thanks.

• play sound from different applications on different output devices (speakers, headphones)

  - by Mike

  I want music (played e.g. via Audacious) to be played on speaker system, and all other sounds produced by other applications (including ubuntu sound effects) to be played on headphones. My computer has sound connectors at its back, and also connectors on its front panel. When I connect both headphones and speakers, only headphones work (I take it, the front connectors take precedence?). Should I purchase another sound card (in addition to the motherboard-integrated sound I have)? When I go to Audacious output settings, I see only the ouput plugin selection list, with PulseAudio selected and options like ALSA, OSS4 etc. But there's no facility to select particular output device (and I guess it wouldn't magically appear even if I had the second soundcard). Is this at all possible to bind specific application to particular output device?

  Some months ago I bought 4 Memory modules of 4GB DDR3 1600 KINGSTON HYPERX.

• Replacing LF, NEL line endings in text file with CR+LF

  - by Tomas Lycken

  I have a text file with a strange character encoding that I'd like to convert to standard UTF-8. I have managed to get part of the way: $ file myfile.txt myfile.txt: Non-ISO extended-ASCII text, with LF, NEL line endings $ iconv -f ascii -t utf-8 myfile.txt > myfile.txt.utf8 $ file myfile.txt.utf8 myfile.txt.utf8: UTF-8 Unicode text, with LF, NEL line endings ## edit myfile.txt.utf8 using nano, to fix failed character conversions (mostly åäö) $ file myfile.txt.utf8 myfile.txt.utf8: UTF-8 Unicode text, with LF, NEL line endings However, I can't figure out how to convert the line endings. How do I do to replace LF+NEL with CR+LF (or whatever is the standard)? When I'm done, I'd like to see the following: $ file myfile.txt myfile.txt: UTF-8 Unicode text

• How to disable touchpad while using trackpoint on a Thinkpad?

  - by January

  Thinkpads (e.g. X230 that I'm using) have both a trackpoint and a touchpad. The touchpad is disabled when typing. However, when I'm using the trackpoint, I often touch the touchpad as well, and generate mouse clicks I'd like to avoid. Does anyone have an idea how disable mouse-clicks on touchpad when trackpoint is in use? EDIT: also, can someone explain how the option of disabling touchpad when typing works? What is being done behind the scenes? Is it an xinput configuration command, and if yes, which one?

• WoW runs faster on GNOME Shell compared to Unity

  - by João Vinholi

  I have been trying to run WoW on Ubuntu 12.04. When I run it on unity, the frame rate is very low and it is impossible to play. Although, when I launch it on gnome shell, for some reason, the frame rate gets very high and the playing experience is very comfortable. The problem is that I prefer running Unity instead of gnome shell, but I like to play WoW too. Is there a way to run WoW on Unity, with no lag?

• How to upgrade Compiz to 0.9.8 in 12.04?

  - by Naveen

  For a very long time, I'm experiencing this bug in Compiz. It makes my windows flash, when rotating the desktop cube. None of the animations work properly execpt the Wobbly windows. However the temporary fix I found on the bug page helped me to reduce the effects, but it's not 100% perfect. Now they have totally fixed the bug in Compiz 0.9.8 for Quantal. I really need to get the official fix on my Ubuntu 12.04. Don't the LTS versions get bug fixes? Sometimes my desktop cube/cylinder appears like this : None of this happened in Lucid Lynx :( Thanks for having a look.....

• Windows 7 and 11.10 side by side from scratch what am I doing wrong?

  - by Bill.Caffery

  I have tried everything I can think of at this point and I'm at a total loss. I have a 2TB drive I want to install Windows 7 and 11.10 (both are 64 bit) side by side, but once I install Windows it must need gpt to work or something because no matter how many times I've removed it, it always returns. If I use gdisk and set the disk as mbr, Windows won't load. Now this last time I ran gdisk and tried to boot into Windows before I installed Ubuntu all the way and ended up at a grub rescue prompt. Any help please? Also let me say I have been searching and reading for days and have tried everything I can find to make this work so this isn't a one time event, it's continual.

• How do I change my PYTHONPATH to make 3,2 my default Python instead of 2.7.2?

  - by max

  I have python3.2 located in /usr/lib/python3.2. I am not sure if that means it's installed but I assume it is for now. Some facts about my system: $ which python /usr/local/bin/python When I type python in terminal I get the following $ python Python 2.7.2 (default, Dec 19 2011, 11:12:13) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. Then to find the path I do >>> sys.info >>> sys.path ['', '/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/usr/local/lib/python2.7/site-packages/pip-1.0.2-py2.7.egg', '/usr/local/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-x86_64.egg', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages'] So knowing all of this, how do I change my default system python from 2.7.2 to 3.2?
