• Is it possible to get a Proxy Authentication Dialog with Ubuntu Server?

  - by Johnny Bigoode

  I've got a VM Virtual Box with Ubuntu Server. I'set the http_proxy variable using export http_proxy="http://1234:linux@proxy:8080" The problem is that Ubuntu will constantly try to connect to the internet, even when I'm not logged in my company's account, so everyday I need to reset my password since Ubuntu will constantly try to access the internet. Also, it's always a problem when I need to authenticate the proxy with a different user/password. Can't I just set it to make a small prompt when it tries to connect to the proxy and fails? Like Firefox, Chrome and every app I have installed with Windows 7? I get this small dialog box that asks for a username and password when it can't access the internet. The Ubuntu Server doesn't need constant internet connection, specially since it's only online for tests over LAN.

• Why is Cocoa using an old version of Unicode? [closed]

  - by Randy Marsh

  While I was searching for something in the Apple docs, I stumble on this: illegalCharacterSet Returns a character set containing values in the category of Non-Characters or that have not yet been defined in version 3.2 of the Unicode standard. On the Unicode website, I find that the latest version is 6.1.0. That's a lot of major versions higher than what Cocoa supports. Does somebody know why Apple doesn't upgrade their framework? My more important question is: Are there problems for not doing having support for Unicode 3.2+? Will I have problems reading Unicode files created on other systems with a more recent version of Unicode?

• Dual Booting Windows 8 and Ubuntu 12.10 - thinkpad x230

  - by user110703

  I am having problems getting grub to load Windows 8 properly after installing Ubuntu 12.10 and Windows 8 on a solid state drive. Here's what I did: Fresh install of Windows 8 using USB recovery drive (partitioned SSD for UEFI) -- Tested windows install and it worked fine Built bootable USB with Ubuntu 12.10 64bit and installed Ubuntu -- Used Ubuntu's installer to partition the Windows 8 partition and install there Reboot - try to load windows 8 from grub -- Ubuntu loads correctly; windows load reports various problems with permissions and not being able to find files - I'll update what the actual errors are Tried to fix the boot problem using boot-repair: -- here's the output: http://paste.ubuntu.com/1384522/ So, this is my first time trying to setup a dual boot system and I think that UEFI is the main culprit in getting this to work correctly. What do I need to

• How can I set a time limit for a game?

  - by Haoda Fu

  I am learning the multi-threading and timer in C# now. But it seems I can't find a good solution. For example, I would like to see how many addition problems that I can solve within 1 min. I would like my program to have A digital clock to count for 60 seconds in the top of my Console. Print a math problem in the middle of my console wait for my input. When 60 seconds is done, stop the math problem challenges immediately (most of time, it is still waiting for my input, but we will stop it immediately). Count how many correct problems that I have solved. Two challenges of the program now. a) how can we make sure the print time and math problem do not mess up. b) how can we stop the math challenges part immediately after time is up

• Where can I find game postmortems with a programmer perspective [on hold]

  - by Ken

  There are a number of interesting game post-mortems in places like GDC vault or gamastura.com. The post-mortems are generally give with a CEO/manager perspective or a designer perspective, or, more often a combination of both e.g DOOM postmortem But I have not been able to find many post-mortems which are primarily from the programmers perspective. I'm looking for discussions and rational for technical choices and tradeoffs and how technical problems were overcome. The motivation here is to learn what kind of problems real game programmers encounter and how they go about solving them. A perfect example of what I'm looking for is Renaud Bédard's excellent GDC talk on the development of Fez, "Cubes all the way down". Where can I find more like that?

• How to reduce errors in dynamic language such as python, and improve my code quality

  - by Martin Luo

  I post the origin question in stackoverflow, some people suggest me to post here I've always have trouble with dynamic language like Python. Several problems: Typo error, I can use pylint to reduce some of these errors. But there's still some errors that pylint can not figure out. Object type error, I often forgot what type of the parameter is, int? str? some object? Also, forgot the type of some object in my code. Unit test might help me sometimes, but I'm not always have enough time to do UT. When I need a script to do a small job, the line of code are 100 - 200 lines, not big, but I don't have time to do the unit test, because I need to use the script as soon as possible. So, many errors appear. So, any idea on how to reduce the number of these problems?

• What issues lead people to use Japanese-specific encodings rather than Unicode?

  - by Nicolas Raoul

  At work I come across a lot of Japanese text files in Shift-JIS and other encodings. It causes many mojibake (unreadable character) problems for all computer users. Unicode was intended to solve this sort of problem by defining a single character set for all languages, and the UTF-8 serialization is recommended for use on the Internet. So why doesn't everybody switch from Japanese-specific encodings to UTF-8? What issues with or disadvantages of UTF-8 are holding people back? EDIT: The W3C lists some known problems with Unicode, could this be a reason too?

• How do I learn algorithms and data structures?

  - by sushil bharwani

  this is in continuation to my previous question where i asked is it necessary to learn algorithm and datastructures. I feel yes it is. Now when i work in a enviornment where i wont ever get the chance to learn it by experimenting or practically or in any assignment. What is the right approach like the right books, right kind of problems, right kind of resources that i can go through to give six months or a year or two to learn it. And also mould my mind in a way that it can relate problems to datastructures and algos.

• "A hard disk may be failing" , but no additional info via gdu-notification-deamon (suggestions?)

  - by blunders

  Got this message after logging in: A hard disk may be failing One or more hard disk report health problems. Click the icon to get more information. On WUBI and 10.04, there was no icon to click, and clicking on made the message go away. After rebooting, the message did not display again. I've got everything on all my hard drives in duplicate, so not super worried about a disk failure, though I am wondering why the message had no info on which disk it thought had problems. Suggestions?

• Is it possible to hide some topics in phpBB forum?

  - by Martin

  I would like to be able to hide some of the topics in a phpBB-based forum temporarily from the users - perhaps with the exception of administrators and moderators. I am using the forum for my students and I have solutions of some problems from exams and tests there - posted either by me or by some of the students. I plan to use the same or very similar problems during the next academic year. So I don't want the students to see them, but I want to make the solutions visible again after the tests; so that I do not have to post solutions to same questions again. Is something like this possible? Is this a standard part of phpBB, or do I need to install some modification(s) for it?

• How to write a network game?

  - by TomWij

  Based on Why is so hard to develop a MMO?: Networked game development is not trivial; there are large obstacles to overcome in not only latency, but cheat prevention, state management and load balancing. If you're not experienced with writing a networked game, this is going to be a difficult learning exercise. I know the theory about sockets, servers, clients, protocols, connections and such things. Now I wonder how one can learn to write a network game: How to balance load problems? How to manage the game state? How to keep things synchronized? How to protect the communication and client from reverse engineering? How to work around latency problems? Which things should be computed local and which things on the server? ... Are there any good books, tutorials, sites, interesting articles or other questions regarding this? I'm looking for broad answers, but specific ones are fine too to learn the difference.

• Flashing task bar(firefox) in lxde panel and ubuntu internal error

  - by arroy_0209

  I have upgraded from ubuntu10.04 to 12.04 and installed lxde. The panel is now customized according to my convenience. The problem is there was a default checked option for "Flash when there is any window requiring attention" in Task bar(window list) and now when I run firefox, at times the concerned bar in the panel window list starts flashing but it is not clear exactly why at that moment firefox requires my attention. Normally this happens after I download some files (pdf files) and keep using firefox. The only solution I have found is to quit firefox and even after that I receive this message "Sorry, ubuntu12.04 has experienced an internal error. If you notice further problems, try restarting the computer." As usual I report the detailed message to ubuntu as suggested and finally restart the computer. So there are two problems, first, exactly why firefox needs my attention at times and second, why immediately after this, ubuntu experiences an internal error. Please suggest what I should do.

• Circle vs Edge collision detection / resolution

  - by topheman

  I made a javascript class Ball.js that handles physics interactions betweens balls as well as painting. In the v1.0, the ball vs ball collision detection and resolution is well handled. In the next version (v2), I'm trying to add edgeCollision handling. I'm having some problems, maybe you will be able to help me. All the v2 branch source code is on github repository : https://github.com/topheman/Ball.js/tree/v2 The v2 demos (where you can see the bug I will be talking about) : http://labs.topheman.com/Ball-v2/#help As you will see on the demo, I have two major problems that I'm having a really hard time to solve on Ball.js : method resolveEdgeCollision : bounce angle is inconsistent method checkEdgeCollision : if the ball's velocity (the length that it runs each frame) is higher than its diameter, eventually, it will pass through an edge, without triggering any collision Any Ideas ?...

• Why won't videos on a particular website play under Ubuntu 13.04?

  - by Sadi

  Very oddly, I cannot watch any videos a TV channel website, for example this one: http://www.kanald.com.tr/GalipDervis/Videolar/ I can see from the frame source that it contains an embedded Adobe Flash video and some Java scripts (all of which don't pose any problems elsewhere). I've tried different web browsers (Chrome/Chromium/Firefox), but it seems I have some sort of video codec problem in my system. I have installed all sorts of gstreamer plugins, codecs, etc. (maybe too many?) to avoid such problems, but strangely I can watch these videos using Linux Mint 15 Live Session on the same machine. I wonder how I can find out why a particular video (like this one) won't work on my system?

• Installing dgen removes Ubuntu-Desktop

  - by aliasbody

  I am trying to install "dgen" a Sega MegaDrive/Genesis emulator, available in the official Ubuntu repositories. But when I try to install, the package manager (USC or even apt-get), say's that he needs to remove those packages before installing : file-roller lintian ubuntu-desktop unzip winetricks Ubuntu always had problems with dependencies like this, and this was the main raison I started using Arch Linux instead of Ubuntu, but with the newest versions (mainly the 12.04 version), I was hopping that those kind of problems had complety dissapeared.. but no :S... So, How can I install this package without removing those packages ? And do I need to fill a bug report for this ?

• Windows Repairs Itself After Ubuntu Boot

  - by pjtatlow

  I have a custom built computer in my home which was running Windows 7 primarily. After I installed Ubuntu 12.04 and upgraded to 12.10, Windows 7 has to perform startup repair after every Ubuntu boot up. For example, I am using Ubuntu for my everyday work, but when I switch to Windows to play one of my steam games, windows fails to boot, and it switches to the recovery partition to "repair windows" then boots windows. The whole process takes about 20 minutes, which is quite annoying. Anyone know why this is happening or what I can do? Thanks in advance!

• How well does Intel 3000 HD work on Ubuntu?

  - by Simon

  Right now i have notebook with Nvidia 8400M GS (I know, it's not good card) and it's impossible to work normally when i'll plugin external monitor (1920x1080). Windows 7 can deal with it without problems (1440x900 on notebook + 1920x1080 external). On Ubuntu i have to choose one screen and turn off the second one. Even with only one screen Ubuntu (Unity or even Gnome3) sometimes hangs for a while, I've not found solution for this yet, but nevermind, it's probably because of my card or/and nvidia's drivers. I'm going to buy new PC, but for now only with integrated Intel 3000HD, and my question is: Should i expect similar problems with this card? Here i've found link to Intel's webpage about drivers - "only community develop them", and i'm a bit concerned. I'll use then only one monitor (the bigger one), but how well does those driver work? Are there any performance tests?

• What are the tactics used to discover what kind of affiliate products will do well in your website?

  - by freethinker

  I'm starting to post some affiliate ads on my website. As it happens, I am not even close to making a sale. I'm not sure if the products I have chosen will appeal to the audience I have. I'm not sure if the volume of traffic is enough to support affiliate programs. I get about 8000-9000 visitors everyday. But since its growing constantly, thats not much of a worry. But I'm surely struggling to figure out what kind of products to market? (its a techie site). Is there a service/tool which can analyze the website and suggest what products will do well and what won't?

• How to determine the right amount of up front design?

  - by Gian

  Software developers occasionally are called upon to write fairly complex bits of software under tight deadlines. Often, it seems like the quickest thing to do is to simply start coding, and solve the problems as they arise. However, this approach can come back to bite you—often costing time or money in the long run! How do we determine the right amount of up front design work? If your work environment actively discourages you from thinking about things up front, how do you handle that? How can we manage risk if we eschew up-front thinking (by choice or under duress) and figure out the problems as they arise? Does the amount of up front design depend entirely on the size or complexity of the task, or is it based on something else?

• Is it save to configure "Shutdown" on "When laptop lid is closed" ?

  - by Takkat

  To setup a laptop owned by a complete PC novice any settings that may become hard to tackle remotely need to be avoided. The laptop will be administrated via SSH. One thing in my list are problems arising from improper wake-ups from suspend or hibernate as they may also affect network accessibility. This is why I thought setting up power management to "shutdown" on closing the laptop lid could be a good idea. However I am not sure if this is a safe way to do. What problems in addition to software not closing properly (and thus not saving their data) could I be faced if I proceeded as planned?
