  • Is programming or computer science in general, all about algorithms?

    - by wakandan
    As a grad student, I find it more and more common for prestigious companies (like Google, Facebook, Microsoft,...) to put algorithm questions in their test and interviews. A few startups I applied to also asked about algorithms. I wonder if algorithms fluency is the most important thing for software developer in those companies? If the answer being yes, what are the best method or resources for one to learn & practice about algorithms effectively? I can't seem to get interested in solving seemingly too complicated problems found in most textbook or websites. Though easily understand basic algorithms (like quicksort, bubblesort,...), I find it immensely difficult to remember and reuse them later. Thanks. P/S: If you ask me what I like, it's building good softwares to solve users' problems innovatively. I suppose that does not necessarily mean the software has to be very complicated.

  • Purchasing a TV show adaptation rights, how does it work?

    - by Mikalichov
    Basically, I was thinking about a game based on a TV show, just for fun, and ended up thinking "well, it's not like it can be made anyway". Or can it? In the present situation, developing a game by myself/ourselves on my/our free time, and then using crowdfunding to purchase the rights is not that crazy, if the show is really popular... and the rights not too expensive. Purchasing the rights of the whole show is obiously a sh!tload of money, but what about adaptation rights? What is the range of price it can be? Is it a percentage of the full rights? Does it depend on the kind of adaptation (novel vs. toy vs. game)? ps: if it can help answer, I was thinking about a MLPFIM retro RPG. Please don't laugh at me.

  • Flash/SWF Editor For Ubuntu 12.10

    - by Chantelle
    First, thank you in advance for any help that you can give a recent transplant from Windows to Ubuntu. I have a question that I have been seeking the answer too but I draw a blank at every turn. I design websites, free of charge, for nonprofit organizations that are just starting and do not have the resources to hire a design firm. I am in need of a flash/swf editor and compiler. I had a program that I used with the awful previous O/S, however WINE would not run the program. Thank you in advance for any help that you can offer. Since I do not earn a dime for doing this, I would prefer if the program was open source, however any suggestions are greatly appreciated.

  • Help deciding on an area of study for a PhD [closed]

    - by ale
    I am going to start a PhD in about 1 year. My undergraduate degree is in computer science and my master's is in artificial intelligence. I want to get ideas about what's going to be hot in say 5 years i.e. what could I spend 3-4 years studying to potentially have expertise that will be applicable to industry and the computing world ? Impossible to answer factually but some ideas and thoughts would be great. I have narrowed my ideas down to AI (yes, even more AI) and information security. AI seems to becoming popular again but security is always a going to be useful. From a career point of view, if I were to stay working in software development then this might actually be the best move but I've always wanted to do a PhD! Many thanks :).

  • Weird keyboard problem

    - by Sebastian
    I just installed Ubuntu on an Acer Extensa 5620 laptop. The keyboard works fine except when I want to type things that require me to use Ctrl+Alt+(any key). I can't use Ctrl+Alt+(any key) shortcuts in any program, but I can open terminal with Ctrl+Alt+T. Ctrl+(any key) and Alt+(any key) shortcuts seems to work though. Also I just installed the game Heroes of Newerth and neither Alt or Ctrl keys seem to work in the game. Any answer would be appreciated!

  • How to install all versions (stable/beta/unstable) of Google Chrome side by side without conflicts?

    - by sobi3ch
    I have the stable version of Google Chrome on my box. And each time I'm trying to install beta or/and unstable versions then I run into the same problem: The following packages will be REMOVED google-chrome-stable The following NEW packages will be installed google-chrome-beta 0 upgraded, 1 newly installed, 1 to remove and 0 not upgraded. Need to get 34.5 MB of archives. After this operation, 3,109 kB of additional disk space will be used. Do you want to continue [Y/n]? I need to remove the first version before installing another. I know I can't install existing packages side by side but I'm looking for solution not for answer like: "You can't do it", I already know I can not. So in summary my question is: How can I install all Google Chrome versions next to each other? (There needs to be a way..)

  • ALSA Mutes Incorrect Audio Device on Headphone Event

    - by Gardiner
    I know what the problem is, I just don't know how to prevent it. When I plug in my headphones, ALSA automatically mutes (and sets the volume to 0) the 'Speaker' entry in alsamixer. If I go in and manually unmute (and turn the volume up) I have sound from my headphones. Question is, how do I change this behavior? I want it to adjust the volume to half, but not mute or set the volume to 0. I'm using Ubuntu Gnome 13.04 Output of amixer scontents Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [on] This answer solved my issue: How can I get sound on headphones without switching back to 'Speakers' manually?

  • How do I disable the upgrade to new version warning? [duplicate]

    - by Anatoliy
    This question already has an answer here: Disable Ubuntu Update Manager's new version warning 2 answers After I allowed Ubuntu on my notebook to upgrade to 13.4, it lost Wi-Fi connection. Network menu does not show wireless access points, but according to syslog it establishes connection. Also, the wireless router provides IP address to the host. I don't want to spend time on debugging and solving the problem that most probably will reappear with new update, so I decided to reinstall 12.10 version. It recognized Broadcom Wi-Fi modem right after the boot, and everything went great, until today I powered it on and suddenly found that it is running 13.4 and all my problems are back! Is it possible to instruct it to stay with 12.10 until I decide to upgrade?

  • How to log frame times in an existing OpenGL game? [on hold]

    - by J Collins
    I have been using FRAPS for some time to benchmark instantaneous frame rates in an OpenGL game for which I am creating maps. Until recently it had been quite reliable. Now however, the bench marking shortcut has been unresponsive and I can't explain why. Ideally I could have a logging system automatically start logging whenever the game had focus, but can't find a good tool to do so. So option a) find out how to make FRAPS reliable again or b) find a new tool. Could one of you kind folks help me? Edit: Concise questions Is there a widely recognised tool to log frame drawing times and rates for compiled applications? If the answer is universally the FRAPs tool, are there any clear cases in which logging will not or should not be expected to work?

  • Adding users to multiple/all sites in Google Webmaster Tools?

    - by Christian
    I didn't find an answer to this, but maybe I didn't use the right terms for my search. So I'm sorry if this is a duplicate. Anyway, my situation is this: the company I work at manages a lot of sites (100+), and we've recently put them all into Google Webmaster Tools under my Google account, which was tedious enough. Now two coworkers are supposed to be added as users for each site, so they can see the data and manage stuff there as well. But I can only find an option to add users for a single site, not for all sites that are currently associated with my account. Do I really have to go through more than a hundred sites one by one and add the two users to each of them, or is there some way to add both users to all/multiple sites at once?

  • VMWare Unity Mode with Ubunty 12.10

    - by Nick
    This is a very difficult thing to search for, and find an answer to because of the unfortunate choice VMWare and Ubuntu both having something called "Unity". My host operating system is Windows 7 - 64 bit, running VMWare Workstation 9.0.1. I have a virtual machine running Ubuntu 12.10 - 64 bit. When I attempt to put VMWare in "Unity mode", I get the following message: The virtual machine cannot enter Unity mode because: - Unity is not supported on the guest operating system. From the VMWare site, there is nothing listed that says that Ubuntu is not supported for this... and I have installed the latest vmware-tools on the guest operating system. It seems like a lot of people have had this issue, but I haven't seen a good resolution to it yet. Does anyone know how to get Unity mode working with Ubuntu?

  • Examining ASP.NET's Membership, Roles, and Profile - Part 18

    Membership, in a nutshell, is a framework build into the .NET Framework that supports creating, authenticating, deleting, and modifying user account information. Each user account has a set of core properties: username, password, email, a security question and answer, whether or not the account has been approved, whether or not the user is locked out of the system, and so on. These user-specific properties are certainly helpful, but they're hardly exhaustive - it's not uncommon for an application to need to track additional user-specific properties. For example, an online messageboard site might want to also also associate a signature, homepage URL, and IM address with each user account.There are two ways to associate

  • Installing programs from a download

    - by user7274
    Hello, my name is Anthony and I'm new to Ubuntu and any other Linux OS for that matter. My question concerns downloading a program, and then installing it. The program is called Remotedroid, it lets you use your phone as a wireless keyboard and mouse. I'm use to windows automatically starting setup upon download and cant figure out how to initiate the install in Ubuntu. The programs website says its compatible with Linux OS and the readme file says to just click the extension remotedroidserver.jar to use, but it wont work and none of the files do anything. I've unzipped all the files and my Java is all up to date as far as i know, I think. I'm just not getting how to run a setup in Ubuntu. I looked around this site for the answer but came up with nothing so if someone could maybe offer some insight I would be grateful. Thank you.

  • Is it a good idea to always use Google as the first step to solving a problem? [closed]

    - by The Rubber Duck
    Possible Duplicate: Importance of learning to google efficiently for a programmer? Avoiding lengthy discussions, as a senior level student in CS, how can I get away from Googling problems I run into? I find myself using it too much; I seemingly reach for the instant answer and then blindly copy and paste code, hoping it works. Anyone can do that. I've read the related threads about being a better programmer, but mostly those recommend practicing on pet projects, which I have done, but again I feel EVERY wall encountered, from design through completion, was hurdled with Google. Do professionals instantly "research" their problem? Or do you guys step back and try and figure it out yourselves? I'm talking about both 'algorithm/design' problems as well as compiler issues.

  • First Steps. Windows Phone game development

    - by anatoliiG
    I'm pretty new in game development. Have a couple ideas wich could be cool. First that comes to mind is to develop a 2D game (kinda puzzles) for Windows Phone Mango. You may ask: "Why Windows Phone?". I answer - I've got solid experience in Silverlight and C#. For me, this is a major advantage compared to other platforms. Please, give advice and suggestions about: What should I read? Best practices. Third party libraries. Silverlight(Only) vs XNA. Whatever I should pay attention to.

  • Securing Facebook

    - by Promather
    Probably like most of you, I am concerned about the privacy of Facebook. Some people suggested that I use the HTTPS address instead. Unfortunately, many links in the HTTPS page itself link back to HTTP. So I am wondering whether it is possible in Ubuntu to redirect any request to: http://www.facebook.com/ to https://www.facebook.com/ This way I feel safer. If you also know the solution for Windows, it might be great to share (probably as a comment to my question rather than answer, as this forum is supposed to be for Ubuntu) so that I can share it with friends.

  • General usage question of vbo

    - by CSharpie
    Firstofall, I am sorry if my question is to broad. I am developing a tile based game and switched from those gl.Begin calls to using VBOs. This is kind of working allready, I managed to render a hexagonal polygon with a simple shader applied. What I am not sure is, how to implement the "whole" tile concept. Concrete the questions are: - Is it better to create 1 VBO for a single tile and render it n-Times in every different position, or render one huge VBO that represents the whole "world" - Depending on the answer above, what is the best way to draw a "linegrid". Overlay with the same vbo using the respecting polygon.mode , or is there a way to let the shader to this? - How would frustum-culling or mousepicking work then, do i need to keep the VBO-data in memory?

  • How can I convince a project manager that there is no way to solve all the compatibility issues?

    - by SAFAD
    I have been working on this project for more than a year now, and we are close to release, the project manager wants the product to be perfect and working in every single aspect. I like that and I love working under the perfection idea, but it seems he is delaying the launch too much because of compatibility issues, he wants the product to work in every single installation, every single configuration possible, and in most cases, the product just works without issues when it's on the hands of the client. UPDATE : yes the product doesn't work properly when there are conflicts, for example, other products that don't use guidelines nor standards to load libraries (causes double library load which leads to failure), cache is another example and so on..... but we warn the clients about the conflict before purchasing and help them fixing it after purchasing I've tried to explain it by giving some examples on major products, he understands the situation, but can not believe that it is near impossible (if it is not impossible) to do what he wants. Hope it is clarified enough for the community to answer.

  • Are there any surveys on to what degree developers like or hate scrum?

    - by dparnas
    Background: During a conference an analyst pointed out in a tweet that developers hate scrum. Myself and another person responded that this was not the case, and started discussing different scenarios on why developers would dislike scrum. One of the scenarios where that lazy developers are not able to hide in a scrum project. They are constantly challenged by the team to contribute. This discussion resulted in a blog post and video http://elsewhat.com/2010/05/20/lazy-developers-hate-agile-and%C2%A0scrum/ I've gotten three comments which I've tried to answer in a neutral way, but they comments do point out that there are some people who loathe scrum (and I am always 100% certain they are not lazy developers). Question Have there ever been a survey among developers on to what degree developers like or hate scrum ?

  • Java EE/GlassFish Testimonials

    - by reza_rahman
    A key question to answer for Java EE and GlassFish centers on proof of successful adoption. To that end, we have made a serious effort to ask Java EE/GlassFish adopters to tell us their stories. There were a number of such stories shared at this year's GlassFish Community event at JavaOne. One that particularly stands out is a testimonial by celebrated Java EE advocate and independent consultant Adam Bien. For those of you that don't know it, Adam was given the "Top Java Ambassador" award by this year's JAX Innvovation Awards. See what Adam had to say here. We'll share more of these testimonials in days to come, so stay tuned.
