• XNA: Runtime differences in ClickOnce install versus development version

  - by Sean Colombo

  I have a game written in XNA, and I use ClickOnce installers to distribute the game to testers. I keep once computer as a test machine which does NOT have development environments installed, so that I can test the installed version. We've found a reproducible bug in our game, but the bug ONLY occurs on the non-development machines that use the ClickOnce installer. The bug is related to some of our code for moving around 3D objects and is not tied to Networking or GamerServices. Are there known differences in the ClickOnce runtime and the version on dev? Are there any best-practices for debugging something like this?

• Is it better to concentrate on one or two research projects throughout undergrad?

  - by AruniRC

  Currently in the 4th semester of engineering in an Indian university. The thing is - is it better to do as many short-lived projects/research work on diverse topics of computer science or stick to one/two projects consistently throughout my undergraduate years? Case in point: currently working on an image-processing project that promises to carry on for a year or so (as per the prof). Does this seem like being over-specialized at too early a level? Although taking on too many things will spread me out thin and in all probability not end up getting any meaningful work done. Especially as I hope to apply for grad school in the US. Would really appreciate any views and suggestions on this.

• Cliché monsters to populate a steampunk fantasy setting dwarven dungeon?

  - by Alexander Gladysh

  I'm looking for a list of cliché monsters for a steampunk computer game (assume one kind or another of casual rogue-like RPG), to populate lower levels of ancient dwarven-built dungeons. Dwarves are a technology/science race in the setting I am aiming for. The world is a low-magic one. I'm stuck after listing various mechanical golems, gigantic spiders (every dungeon must have some of them!), and maybe a mechanical barlog as a megaboss. What would player expect? What are the key cultural references for such setting? I know a couple of games with suitable steampunk dwarves, but none are detailed enough in the underworld monsters area. Please point me in the right direction. (If you have a single funny monster suggestion, please mention it in comments, not in answer. ;-) )

• Is shared hosting enough for feed reader app?

  - by Mahdi

  I'm developing an Feed reader app. Feeds are downloaded to my server when someone requests it. then they download to user's computer. There will be 1-2 minutes cache for popular feeds. We expect that there will be 1000-5000 users (that use our app) Is a shared hosting (which currently serves almost 100 website, and it will serve 500 websites at maximum) enough for this purpose? or we should look for VPS or Dedicated hosting? Note: Our shared hosting plan has unlimited disk space and unlimited bandwidth.

• Bluetooth from the command line in 12.04?

  - by azzid

  I've been trying to pair up my bluetooth keyboard with my computer after reinstalling from a standard ubuntu 12.04 to a minimal install. In the minimal install I have no gui, so I've been trying to use the various command line tools available, but I can't figure out how the pairing is supposed to go. Pairing when I had a gui worked flawlessly. I've asked for help here: http://ubuntuforums.org/showthread.php?p=12234695 No one has replied but a lot of details of my situation is available there. How is one supposed to pair bluetooth devices from the command line?

• What does a programmer really need to become a professional?

  - by Dehumanizer

  There are huge numbers of programmers, especially juniors, who need good assistance in becoming professional. I've heard a lot of about "books every programmer should read", etc. I have two years of programming experience, feel good in C++, but currently have a strange feeling, that I do not know anything about programming. I should read Algorithms by Cormen, Code Complete by McConnell etc., but I don't know the exact steps required to become a professional. What should we do? What should we learn? Operating systems? Computer organization? Algorithms? C++ in depth? How much time do we have to spend to become what we want?

• An intern interview with Microsoft [on hold]

  - by Wobbles

  I'm currently in my second year(Computer Science and Mathematics). In two days I have an interview on campus with Microsoft. I'm a bit nervous, because this will be my first in person interview. I have done reviewed basic things like linked list and binary trees. I am not really sure what kinds of questions I'll be asked. Has anyone been to such interview? If so what's it like? What kinds of questions will I be asked? Any help/suggestions will be much appreciated! Also can someone provide me with a list of things I ought to know for the interview?

• Unable to connect to internet

  - by Peter Schriver

  I just upgraded to 12.10. Everything appears to go well but I am unable to connect to the Internet. The LAN is fine and I can view my shared files but no e-mail or access to web pages. My other computer which is running 12.04 or older seems to connect fine. I only upgraded one to make sure things would be ok. I am currently connecting fine with a wireless Windows laptop. Output from cat /etc/resolv.conf # Generated by NetworkManager nameserver 127.0.0.1

• MacBookPro 7,1 can only see one cpu

  - by gozzilli

  On a MacBookPro 7,1 running ubuntu 11.10, System monitor only sees 1 core (instead of 2). cat /proc/cpuinfo | grep 'cpu cores' also gives: cpu cores : 1 I followed this guide and added acpi_apic_instance=2 to the line with GRUB_CMDLINE_LINUX_DEFAULT, but that doesn't seem to change the situation. What can I do? I'm using rEFIt, installed under MacOS, and running in dual boot with MacOS. After the rEFIT menu, I'm still presented with the GRUB menu (I'm assuming that's normal). I saw similar posts on this matter, but could not fix my problem with what they suggested. EDIT: With the method mentioned above the computer runs sometimes with 1 core and other times with 2. Why is that? How can it be fixed?

• Breaking in to Programming

  - by Kevin

  I've noticed that there is a gap between getting formal education in computer science as a student and entry-level/junior programming jobs. Obviously entry-level programming requires that you know some programming but how much do you need to break in? I'm in a QA non-coding role with basically a minor in CS, looking to improve my own programming skills to eventually switch industries. However I'm completely at a loss as to what I should be focusing on learning and am curious as to the steps other people have taken to get experience post-undergrad.

• Learning C++ but wanting to develop iOS Apps

  - by DiscreteGenius

  I'm a computer engineering student and taking my second programming class. I'm learning C++ using "C++ Primer Plus" 5th edition by Prata. I want to develop for iOS. I understand the main language for Xcode is Objective-C. Am I hurting myself by learning C++ before any other language (notably before my desired lang Objective-C)? There's got to be a reason the university requires C++ to learn as a basis language. Please offer any helpful guidance or how I should go about this. Thanks//

• Ubuntu multiple issues (blank screen)

  - by Donavon

  Computer Specs I am having difficulties, to get Ubuntu 11.10 to work. For the 11.10 version, if I click install, or if I click try Ubuntu, I only get a blank screen, that just stays there. If I use "nomodeset", it changes to a loading screen and after about 2 minutes it goes back to black screen - however, before it goes black, i get a few errors, like: bad target number, or passwd error mode (something like that). I've also tried (xforcevesa, i915.modeset=0, nomodeset, radeon.modeset=0, i915.modeset=1) I have also tried the alternate installation, which installed fine, however when I boot up, select it from "grub", it goes black. I did manage to install 10.04, however the screen resolution was 800x600 and I couldn't fix it to 16:9 (my resolution). I don't wanna use 10.04, because I would like the new one 11.10, and would like to use it. Any help would be GREATLY appreciated. Thank you

• What are the benefits vs costs of comment annotation in PHP?

  - by Patrick

  I have just started working with symfony2 and have run across comment annotations. Although comment annotation is not an inherent part of PHP, symfony2 adds support for this feature. My understanding of commenting is that it should make the code more intelligible to the human. The computer shouldn't care what is in comments. What benefits come from doing this type of annotation versus just putting a command in the normal PHP code? ie- /** * @Route("/{id}") * @Method("GET") * @ParamConverter("post", class="SensioBlogBundle:Post") * @Template("SensioBlogBundle:Annot:post.html.twig", vars={"post"}) * @Cache(smaxage="15") */ public function showAction(Post $post) { }

• How long does Wubi take to download and/or save place?

  - by Oscar Godson

  I'm downloading Wubi now and it's been downloading the ISO torrent for maybe 2hrs-ish. Is there anyway to check how far along it is? Also, is there a way to save my place or if I cancel this or my computer dies, will it lose the place? If I DO lose my place. Can I download a ISO myself and place it somewhere that Wubi will grab from so it just installs it, not downloads the ISO? (this way I can watch the % too) Im at a conference and my internet is fluctuating between 3-7MBs...if that helps

• QotD: Eben Upton on Raspberry Pi Model B Shipping With 512MB of RAM

  - by $utils.escapeXML($entry.author)

  One of the most common suggestions we’ve heard since launch is that we should produce a more expensive “Model C” version of Raspberry Pi with extra RAM. This would be useful for people who want to use the Pi as a general-purpose computer, with multiple large applications running concurrently, and would enable some interesting embedded use cases (particularly using Java) which are slightly too heavyweight to fit comfortably in 256MB.The downside of this suggestion for us is that we’re very attached to $35 as our highest price point. With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard.Eben Upton, a founder and trustee of the Raspberry Pi foundation, in a blog post announcing the change.

• Disabled WiFi but it keeps re-enabling itself; want it to stay disabled

  - by Mike Uresti

  I have an Alienware X51 desktop with a wireless card, I have it connected via ethernet and want to permanently disable WiFi from ever using itself. When running Windows, I go to device manager and rightclick-disable the Wireless card and that takes care of my problem. Is there a similar method using Ubuntu 14.04? For now, I click on the network icon in the system tray and uncheck 'Enable wifi' but it seems to turn itself back on as I use my computer, I think I have the incident isolated to something with Steam. It seems like after I start the Steam client it always is re-enabled. Hopeful answer: Just disable/remove/block wireless card from ever working.

• assistance recovering/reinstalling/installing ubuntu and win7

  - by razzrat

  New computer with Windows 7 installed, I defrag, shrink, re-boot from Ubuntu LiveUSB, go to gparted and look at partitions before installing Ubuntu....for some reason Win7 is still taking up 400G of my HD! I resized partition down with gparted, exit and yes of course I can't boot into Windows. When I go to install Ubuntu in new large unallocated space I get a blank screen at the point you are asked what kind of installation you want. I have Ubuntu 12.04 LiveUSB, Windows 7 re-installation disk and driver disks also. The HDD currently has 3 allocated partitions: 'diag' fat16, 'recovery' ntfs and 'OS' ntfs which has a red '!' next to it.

• How do I find fun companies?

  - by the_great_monkey

  When looking for jobs, I'm not sure how to determine whether the company is fun to work for or not. I want to work in companies that are open, innovative, and make a good contribution to the world of computer science. For example, Dropbox looks like a very fun company and its existence is very important. How do I spot this in job advertisements? EDIT: I should note that I live in Australia, so many of the fun companies that I know does not have any office here. I know only a handful of fun companies in Australia – including Google in Sydney. But I don't know that many.

• How to enlarge ubuntu partition

  - by Vineet

  I installed Ubuntu 11.10 recently by making a 5.6GB partition from the Ubiquity installer. I wanted to upgrade to 12.04, so I opened the Update Manager and clicked on 'Update Packages' (I was following this guide) After clicking, it said that there was too little space available. So, I want to enlarge my Ubuntu partition so that there is appropriate space for upgrading. I downloaded Gparted. I read another guide which said my computer won't boot if I resize the Ubuntu partition because '/boot will be misplaced and I will have to repair GRUB2 myself.' So how do I do this easily? Thank you in advance.

• How can I manage keyboard shortcuts in 11.10 Oneric?

  - by Mike

  In 10.04, I've had a keyboard shortcut defined via it's keyboard settings applet. Recently I have upgraded to 11.10 (I use gnome-classic). This shortcut still works, but I can't find it in System Setting's Keyboard applet. This means I don't know how to disable it. Not that it bothers me too much (now, at least), but not being able to control my own computer doesn't seem very pleasant. Where does Ubuntu store my keyboard shortcuts? BTW, I do not use compiz, and I can't find my shortcut in gconf either.
