• How can I know if programming is right for me?

  - by user66414

  I have an IT background and was pretty confident until an opportunity came up at work to go into programming(C#). I have never programmed before this, and the software I am programming for is a program I have never used before (a 3D modeling software). It has been 6 months since then and I feel like giving up. I didn't get much training... about 3 weeks of training spread out over the last 6 months. I think I would be good at programming but this experience is kinda making me rethink my decision. I'm not sure if it's just me, or if this frustration is normal. How can I tell if programming is right for me?

• Does FP mess up your OOP skills?

  - by bonomo

  I've been learning functional programming in Haskell and F# for awhile and now when I got some skills it gets harder for me to think in OOP way and program in C# and JavaScript. Everything seems to be ass-backwards there with classes, interfaces, objects and I often stare at the screen trying to think of a better way around without using them. This is something that scares me, because I didn't have problems like that before (not knowing that the same stuff can be done in a different way). So I am concerned as I don't want to loose myself as a OOP developer, because this is what I do for living. Is it a normal thing? Shall I rather stop doing FP? How did you manage to cope with it?

• Over-Current condition on port 7 or 8

  - by Dymatic

  I am having a problem with my USB ports. It shows over-current conditions on ports 7 and 8. I have heard that this is caused by a damaged USB port, and since it is detecting it on two ports it seems that I have two that are broken. I do indeed have two that do not work, so that is not the issue. What I would like to do is disable whatever program is running over-current condition checks. tty's are unusable at this point. Every few second a new over-current condition occurs. Here is the output of dmesg: http://pastebin.com/CuFKRGue Is there an easy way to disable these checks or damage the ports to a point where it will no longer check? Fixing them is not important or an option.

• Limit the size of a directory by deleting old files

  - by Sulliwane

  I have a IP cam which save its recordings in a specific directory named Camera1 in my Ubuntu Server 12.04. I would like to limit the size of this folder to 5 gigs, by deleting -say once a day- the oldest files. I first checked the quota program but it doesn't seem to allow the creation of new files and deleting of the old ones. So I think the best workaround would be to run a bash script ? But I have no idea how to write it... Thank you guys !

• I love video games and know I want to work in the sector but hate programming

  - by normyp

  I just hate how I'll put in 8-10 hours in and get little to nothing back. The return results for your efforts seem to be pathetically small the majority of the time and I don't find that rewarding enough for me to put in the time and effort to learn programming and make myself better. I've heard game design is fun and I think I'd love that but apparently you can only get into that really if you can program, is that true? I feel a bit lost because I'm doing a degree in Games Technology and am worried that I'm sending myself into a job I'll hate.

• What are deferred callbacks?

  - by tentimes

  I understand the idea of a callback, where I pass a function into another function and that function then uses the supplied function at will. I am struggling to understand deferred callbacks, even after googling it. Could someone provide a simple explanation please? I program in Ruby, but also know C/C++ a bit, but most of all I was a experienced assembly language programmer. So I am wondering is it a bit like a stack of callback addresses that get pop'd? I am hoping to learn jquery or node.js and these deferred callbacks seem integral to both. I understand basic threading principles (though mutex object makes my head hurt ;)

• Should I prevent search engines indexing tag/category pages?

  - by Macha

  On my site, I currently have no special rules for search engines. It is a blog, statically generated using a Python program. When I search for some of my articles on Google, there is usually a tag or category page included in the results. Sometimes it even ranks ahead of the article itself. Obviously, as these links aren't always going to have the article on them, this aren't the results I want people to click on. So, I'm thinking of setting noindex on these pages. Is there any possible downside to doing so? Is this possible to do via robots.txt, or do I have to add it to all the relevant templates? All I can find for robots.txt are ways to stop the search engine crawling those pages, which isn't what I want - while I don't want them indexed, it's still the only surefire way to find all my blog posts.

• Not able to create screenshot of when menu is active [closed]

  - by gotqn

  Possible Duplicate: Screenshot of active window doesn’t work I am using Ubuntu 12.04 and I am searching for a program that will let me to do screenshot of my menus too. Also, it will be very useful if I am able to "cut" only part of the new screenshot and save it as a new image. At this moment, when a menu is shown (for example I click on my clock and the calendar is shown) the "print screen" button is not working. This happens to with applications launchers menus in the left navigation panel. On windows I am using Gadwin Pro. Is there any alternative on Linux?

• Where does the light come from, using Maya/Panda3D?

  - by Aerovistae

  Total noob to Maya. Total noob to Panda3D. Planning on becoming really good at both as soon as I have free time to do so, but right now I have an assignment due in a few hours which requires this: (The part which confuses me is bolded.) Model and texture a vehicle and two different obstacles Build a scene graph in Panda with a plane, the vehicle, several copies of each of the obstacles, and (at least) a direction light Program vehicle movement, constrained to a plane (no terrain) Working headlights Vehicle collides with obstacles How do I attach a light source to a model? I'm assuming this is done in Panda3D but I'm sufficiently new to this that I wouldn't be astonished to hear it's part of the model.

• How to get presentation tools like windows office without windows office?

  - by ved2254

  On working with MS Office and LibreOffice I found that (as countless have) Libreoffice is not quite up to Windows' level. I would like windows Office on Ubuntu but that means using Wine, which I don't want. I tried using wine but it went a teansy bit wrong (where i have no idea). So I tend to avoid it. Hence the question : Is there any way I can get any program/plugin/patch/anyting-I-missed to get same functionality as MS Office in Ubuntu? I have Ubuntu 12.04 64bit (if required).

• How to manage/control software versions?

  - by Zwie

  I'm facing a problem to create a version control outline for several already existing software parts for my company. Until now no one - expect for the developers - knows that there are different versions, which is the reason for the outline. In fact, I'm supposed to set up the future version control and communicate all this with our management... So, the question is how to create such a outline. Are there principles to follow to make software versioning easier or even a good program to map all versions and there compatibility? And are there generally good approaches to control software versions?

• What is the worst programmer habit?

  - by 0x4a6f4672

  Many people get into programming because programming is fun. At least in the beginning. After some time doing it professionally, programming is no longer fun, often just hard work. Sometimes we develop bad habits along the way to make it fun again. Some bad habits of programmers are well known, for example the "I fix that in a second" habit, the "reinvent the wheel" practice or the "all code except mine is crap" attitude (which often leads to "I will re-write the entire program from scratch" syndrome). There are things which a programmer should never do. What is the worst programmer habit?

• Why to let / not let developers test their own work

  - by pyvi

  I want to gather some arguments as to why letting a developer testing his/her own work as the last step before the product goes into production is a bad idea, because unfortunately, my place of work sometimes does this (the last time this came up, the argument boiled down to most people being too busy with other things and not having the time to get another person familiar with that part of the program - it's very specialised software). There are test plans in this case (though not always), but I am very much in favor of making a person who didn't make the changes that are tested actually doing the final testing. So I am asking if you could provide me with a good and solid list of arguments I can bring up the next time this is discussed. Or to provide counter-arguments, in case you think this is perfectly fine especially when there are formal test cases to test.

• Code review vs pair programming

  - by mericano1

  I was wondering what is the general idea about code review and pair programming. I do have my own opinion but I'd like to hear from somebody else as well. Here are a few questions, please give me your opinion even on some of the point First of all are you aware of way to measure the effectiveness of this practices? Do you think that if you pair program, code reviews are not necessary or it's still good to have them both? Do you think anybody can do code review or maybe is better done by seniors only? In terms of productivity do you think it suffers from pairing all the times or you will eventually get in back in the long run? Thanks!

• How to I teach my artist to do arts for games?

  - by Holm76

  So my girlfriend is an artist and I'm a programmer and we often talk about joining talents and doing some small games or other fun stuff for the different popular platforms currently out. But because I haven't really done any serious games development yet I have a hard time explaining to her how she should create or package the assets she'd make so we always end up not doing nothing about it. What I'm mostly thinking about here is when doing frame by frame animation. I know sprite sheets are used for this kind of thing but then comes questions like frames per second and stuff like like that. Not program wise but art wise. Is there a reference site or sites out there that teach someone with the skills of art how to manage and arrange the assets in sprite sheets and other stuff in words that artists understand?

• In what order do people build websites?

  - by Corey

  For a website, you need to have an idea, you need to have a design and you need to have data, events and output, right? Whether it be a blog, web app, Q&A site, search engine... Anyway, that is only slightly related to my question. My question is, when designing a website, providing I know the purpose, what should I start with? Should I start with the CSS, design and look&feel using dummy data first, or should I program in the logic, events and output, and style it later? What is the design process of most websites that are built from the ground up?

• Opening a Gtk.Window that covers Launcher and Panel

  - by BigWhale

  I am trying to create a GtkWindow that would be on top of all the windows. This includes Unity's Launcher and Panel. I am working on Kazam screen recorder and one of the options of the program is recording an arbitrary area of the screen. For this, I open a GtkWindow and let user resize it and move it around the screen to the desired location. The problem is when user wants to resize the window over the Panel (or Launcher). It can't be done. It seems that window manager is preventing this. I can move the window under panel and launcher if I ALT-drag it, but the problem because area selection window stays below Launcher and Panel. Any ideas are more than welcome.

• How do I recover a BTRFS partition that will not mount?

  - by Tony

  The installation for 12.04 kept failing, and the solution was to have the installer ignore the btrfs partition that I have previously been using for /home. Now that it's installed, I've been trying to get it to mount the btrfs partition so that I can access my 70GB of files. It won't mount, and btrfsck errors out with the following three lines: parent transid verify failed on 31302336512 wanted 62455 found 62456 parent transid verify failed on 31302336512 wanted 62455 found 62456 parent transid verify failed on 31302336512 wanted 62455 found 62456 Can someone please tell me how to get this partition working? I've read online that I can probably recover the data using btrfs-restore, but I can't find that program anywhere.

• AMD control center doesn't save preferences

  - by Fault

  Everytime when I edit the monitor preferences in AMD to multi-monitor or to a multidesktop, when I press save or apply the program just closes with no errors and the preferences hasn't been saved. If I try to do it via the Displays app that is built-in in ubuntu 11.10 I get the following error: The selected configuration for displays could not be applied required virtual size does not fit available size: requested=(2560, 1024), minimum=(320, 200), maximum=(1280, 1280) I don't know if it helps but my graphics card is a ATI Radeon HD 4800 and my monitors are both 1280x1024. I'm running the proprietary driver without post-release updates because I always get an error trying to install that one.

• Corsair Hydro i series cpu cooler fan control

  - by user214690

  Im relatively new at Ubuntu and have found an answer to basically every single issue ive ever had thru this site... Otherthan this. I have been toying with the idea of a Corsair h80i for my dual boot system (win7/U12.10) and mostly use it in ubuntu. I have done some research on the interweb regarding fan control in linux and nearly ran up short untill I came across this thread: http://ubuntuforums.org/archive/index.php/t-2096166.html And it seems to have worked around it. (altho I have not tested it for myself) Is there any program/library/source that can be used to control the fans without having to MacGuyver it??

• How do I get "ruby" to do what "ruby1.9.1" does?

  - by Daniel

  I want to start off by saying... I really don't need to be using 1.9.2. I understand that you don't ever, ever use Python 3.2, so if the common advice is that I should use 1.8, I'll do that. But don't tell me to do that because it's easier. Whatever version I should be using, though, the question is still relevant: What's a good way to make one command do another command? (I suppose I could write a c program to launch ruby1.9.1, call the executable ruby, and put it in my bin, but this seems like less than a good idea)

• Is there a good reference manual for ruby/rails?

  - by Kevin

  I've found switching from Java to Ruby/Rails to be very difficult. I feel like the rails books and websites that I've seen are program by example, and I have yet to see anything like a complete reference. In the java/spring world there is plenty of examples but also very thorough reference manuals. So even though I can get toy application xyz up and running in an afternoon with rails I'm apprehensive about doing anything of significance. I'm willing to admit that maybe this is because I've done java/spring for a few years and have near zero experience with ruby/rails. Just wondering if anyone else has run into this or if I'm missing something.
