• How can I authenticate Ubuntu Software Center with user password?

  - by user71852

  I would like to be able to use the password associated with this account to install packages with the GUI. Ideally, I would change the settings so that any user with sudo permissions could install packages. If that is not possible, I would like to be able to list all users that should be able to install. I know that this involves making changes to Policy Kit, and I have read a page with a similar question. However, I must need information specific to my own problem, because all my attempts so far have failed.

• How would you tackle a pattern-finding program?

  - by Neil

  Just to be clear, I don't think this should be question better suited for stackoverflow.com simply because there's not a single answer but a wide range of possible solutions, making this question far more subjective in nature. I was curious how you guys would tackle a pattern-finding program, which is to say I'd do the following operations: I enter in some input. Program predicts my next input based on all previous inputs. Rinse. Repeat. Since the amount of input I could provide is so varied, including empty strings, conventional means such as switches or regular expressions are out, since it would require you to have an inkling of information about what to expect. I was thinking about some form of genetic algorithm, yet even then I don't have a clue as to how to approach a problem of this caliber. I think some feedback mechanism would be necessary as well as to let the program know how close it was. Anyone had to do a similar type program before?

• F# - When do you use a class instead of a record when you do not want to use mutable fields?

  - by fairflow

  I'm imagining a situation where you are creating an F# module in a purely functional style. This means objects do not have mutable fields and are not modified in place. I'm assuming for simplicity that there is no need to use .NET objects or other kinds of objects. There are two possible ways of implementing an object-oriented kind of solution: the first is to use type classes and the second to use records which have fields of functional type, to implement methods. I imagine you'd use classes when you want to use inheritance but that otherwise records would be adequate, if perhaps clumsier to express. Or do you find classes more convenient than records in any case?

• Bitmap & Object Collision Help

  - by MarkEz

  Is it possible to detect when an object and a bitmap collide. I have an arraylist of sprites that I am shooting with an image. I tried using this method here but as soon as the bitmap appears the sprite disappears, this is in the Sprite class: public boolean isCollision(Bitmap other) { if(other.getWidth() > x && other.getWidth() < x + width && >other.getHeight() > y && other.getHeight() < y + height); return true; }

• Which one is better to get started? [closed]

  - by vanangamudi

  Which one of the open-source game engine is better to get started? I read several threads over several forums and found that it is better to write own game engine specific to application. But I need to know the requirements of a game engine, other than Graphics, Physics and AI... Many people suggested Unity, But I need open-source version so that I can have a look at implementation... so I google rigorously and found some unknown game engines(at least to me) Unvanquished Cube Spring Pyrogenesis Torque3D CrystalSpace Panda3D Delta3D Irrichlt OpenArena AlienArena (please list others if I missed anything....) FYI: my present focus is on FPS/TPS. Can you tell me which one is better at performance if possible? Torque3D claims to be the best opensource engine - is that true, and if so to what extent?

• Live USB does not work

  - by MARUF SARKER

  I've made live USB using these "Universal-USB-Installer-1.9.1.9", "unetbootin-windows-581", "YUMI-0.0.8.0" & "LinuxLive USB Creator 2.8.18" in "FAT32" format, but unfortunately I could not boot using the pen-drive. My BIOS supports boot from USB drive. When I am booting from the live usb, it just show black screen with a blinking "_", but nothing happens after that( I have waited more than 10 minutes, but nothing happens). So, can anyone please help me on this? [Additional Info.: I've made Bootable USB using PowerISO and that booted, but it was not possible to access the USB normally afterwards,because PowerISO formatted the USB Drive as RAW(or anything I don't know) and it became 8GB to 700MB, afterwards I had to format it using MiniTool Partition manager.]

• Where actually did they spend money? [on hold]

  - by WannabeProgrammer

  I am a total beginner in the field of game development. Every time I saw or read an interview session with any indie developer they mention about the amount of money they spend on developing a game. I want to know where exactly did they spend the money ? Just imagine that you are making a game for mobile devices from scratch , where and all will you be spending your money to make one ? Is it possible to make games for mobile devices without spending any ? If yes , then it makes more sense for a indie game developer who is talented but comes from a very weak financial background. Thank you.

• How does one manage perfectionism in programming? [closed]

  - by Craige

  Possible Duplicate: Where do you draw the line for your perfectionism? First of - I'm a perfectionist; I know and accept this. Problem is, this really is a counter-productive programming trait. It's a never-ending endeavor that hinders productivity as you find a new and "better" way you should be doing something. To me, if you're not doing it right, then don't do it at all. How does one manage such a characteristic in programming?

• Is it a good practice by commenting with owner name? [closed]

  - by fifth

  Possible Duplicate: How do you keep track of the authors of code? Here's several scenarios which may comment with owner name: bug fixing, i.e. // fixed bug 123 by xxx, solution is ... ... fixme/todo tags, i.e. // TODO: .... by xxx. hacks, i.e. // HACK! ... by xxx For case #2, please refer to Comment Tags The obvious advantage is that we can ease tracking by names. The downside is the risk of abuse. Actually my previous company allowed this way of commenting style, but current employer completely disallows names appearing in code. In my opinion, I would vote for discreetly commenting with author names. I'm open to hear from you if this commenting style is good or bad. Thanks.

• Le trafic Internet rétablit en Egypte, les FAIs locaux reprennent du service

  Le trafic Internet rétablit en Egypte, les FAIs locaux reprennent du service Mise à jour du 02.02.2011 par Katleen L'Internet était devenu une denrée rare en Egypte, comme nous vous l'expliquions dans la news précédente. La décision du gouvernement d'isoler numériquement son pays, en y bloquant toutes connexions (Net, mobiles, etc.) avait scandalisé le monde entier et n'avait cessé de provoquer des réactions outrées de diverses personnalités, États, ou entreprises. Une pression internationale trop dure à supporter ? C'est possible, puisque depuis quelques heures, la Toile semble avoir repris l'Egypte dans ses filets. Les quatre fournisseurs d'accès locaux ont repris du s...

• Collision for mobile game

  - by zemiguel12

  I'm writing a little game in as3 using Starling, and I need to check collision between 2 boats that can rotate. I don't need the pixel perfect collision, but bounds collision is not enough too. The boat look more or less like this: I was thinking about create one square on the back of the boat and a triangle on the front, than for each boat, check if the square collide with the other boat square or triangle, and the same for the triangle. I just don't know how to do that, I don't know if it's possible with the Shape.hitTest, or if it's the best way to do that. What can I do?

• Intuitive "Take Screenshot" key mapping used by games?

  - by Hatoru Hansou

  I recently had a problem testing my game on Linux Ubuntu. The Print key is intercepted by the desktop environment and It never reaches the game. Rather than fighting this, I will simply use any other key or key combination to trigger the screen capture functionality. Now, using the PRINT key is very intuitive because people already expect this behavior. What other keys are a good idea to use to take screenshots? And if possible elaborate why, have other apps/games used that key?

• Silverlight 4 Theme refresh including RIA Services templates

  The feedback from the Silverlight 4 application themes released and the latest in process have been overwhelmingly toward the positive. We appreciate the feedback and hopefully you appreciate the transparency in the process.

• Software purchases & accounts issue

  - by user1735003

  I have installed 13.10 on a new computer and want to tranfer my purchase (Braid) there. I have read this page about how to do this. However, when I log in to https://software-center.ubuntu.com/subscriptions, nothing appears. My guess is that when I purchased this game, I used an older email address than the one I am currently using. Ideally I would like to be able to transfer this purchase to my current ubuntu one account. Or, if this is not possible, at least to have a chance to know with which account this purchase has been done so I can have a try to reinstall it somewhere else. NB: In the Ubuntu Software Center on my older computer the game is still there and marked as "already purchased". EDIT: This is not an upgrade issue, as my old computer has not been upgraded to 13.10, and my newer computer is, well, new, 13.10 being its first OS. Note that I don't see my purchases on the software center web site on my old as well as my new computer, which makes sense.

• Can I host my website through gitlab like you can with github pages?

  - by BenWatkinsArt

  I would love to use git to host my website, and would love a platform I can log into online to go along with it (something like Github). You would think in which case, that Github pages would be the perfect route for me, though I don't want to use Github pages. I would like to host this all on my own servers like you do with Github enterprise (but for free). I have found Gitlab and was wondering if there is anyway I can use Gitlab like Github pages. Is it possible?

• What do you need to master a language and its technology? [closed]

  - by LongTTH

  Possible Duplicate: how to really master a programming language Let say about Java(just a sample, you can talk about C#, PHP, C++ ... it's just similar) and 10 (ten) levels, 1 is newbie and 10 is master. How can you identify someone at which level based on his knowledge? I do not tend to compare languages, I do tend to know what indicate a master or a newbie in a language and its (language's) based technology. Yeah, I know there aren't on earth a language stand alone, it always come with a technology with it. Let say in Java, you can memorize all of its keyword and syntax in just few days, but to know it (I mean do something with it effectively), you must read the Oracle (Sun) javadoc many many times (I'm not mention the 3rd party product yet).

• Laptop battery sometimes does not charge?

  - by user1880405

  So on my Asus K56C laptop running Ubuntu 14.04 (was same problem in 13.10) I got a problem that from time to time after I use laptop without cable (just on battery) it stops charging with cable. I can still use laptop indefinitely on cable, but it's not charging. The only solution is to remove and reinsert the battery, then it will charge. Now I wonder how does laptop 'knows' that battery was reinserted, and is it possible to simulate that from Ubuntu, maybe some command which refreshes battery? P.s.: this is not happening on Windows 8.1.

• Web host that handles excess php mailing [closed]

  - by CyberJunkie

  Possible Duplicate: How to find web hosting that meets my requirements? I'm having trouble choosing a host that meets my application's needs. Please kindly inform me what I should look for when choosing a web host. My application is similar to a reminder service that reminds users of events that they scheduled. I'm sending emails to users through a PHP script. I'm not sending one email to multiple recipients. Each recipient receives a different message. I plan to use cron jobs every minute and expect the application to send roughly 200 individual emails in 1 hour (for a small user base that may grow). I don't have hosting experience with this type of application. I plan to start on a shared host and move up in the future to vps or dedicated. Most shared hosts that I looked into allow 50-100 emails per hour with delays between mailings. What do you recommend?

• Demographics and interests reports in Google universal analytics

  - by Dyf

  I have an issue with Google Analytics, can't seem to find a guide how to activate Demographics and Interests reports. I am using the new version of analytics (Universal Analytics) and the script code looks something like this: (function (i, s, o, g, r, a, m) { i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () { (i[r].q = i[r].q || []).push(arguments) }, i[r].l = 1 * new Date(); a = s.createElement(o), m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m) })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga'); But the guide I found on google's page is for the old version (Classis Analytics). Does anyone know how I can activate this on Universal Analytics? Is this even possible?

• Is there any way around the field-of-use restrictions in Java?

  - by Muton

  Current field-of-use restrictions defined in "Oracle Binary Code License Agreement for the Java SE Platform Products" prohibit its use in embedded systems. "General Purpose Desktop Computers and Servers" means computers, including desktop and laptop computers, or servers, used for general computing functions under end user control (such as but not specifically limited to email, general purpose Internet browsing, and office suite productivity tools). The use of Software in systems and solutions that provide dedicated functionality (other than as mentioned above) or designed for use in embedded or function-specific software applications... are excluded from this definition and not licensed under this Agreement. Do these restrictions also apply to OpenJDK and other possible implementations? Is the only way to use Java in such an environment to acquire a separate license from Oracle?
