• Why isn't Chrome rendering images and fonts correctly?

  - by user287558

  I have an Acer monitor and an Intel Pentium 4 running 12.04 32-bit. Chrome renders all webpages like this: This is how CNN should look: I have Firefox installed and its images/fonts look fine. I am new to Ubuntu and comfortable with using Terminal. Beyond that, I have no idea what I'm doing. This happened all of a sudden a few weeks ago. Any suggestions would be very much appreciated. Thanks in advance.

• Algorithm for Learning development

  - by user9057

  Hi all, This is a fairly general question. I know a bit of Perl and Python and I am looking to learn programming in more depth so that once I get the hang of it I can start developing applications and then websites. I would like to know of an algorithm (sequence of steps :)) that could describe my approach towards learning programming in general. I have posted small questions on Perl/Python and I have recieved great help from everyone. Note:- I am not in a hurry to learn. I know it takes time and that's fine. Please give any suggestions you think are valid. Also, please don't push me to learn Lisp, Haskell etc - I am a beginner.

• Nexus S 4g not detected by computer

  - by Newbie in over his head

  A little bit of a disclaimer, I have very little knowledge of the correct terminology for some of the things I'm going to ask about, and I apologize in advance I have a Nexus S 4g phone that is, at the moment of writing, connected to my 11.10 computer through its USB charger cable. In the past, connecting the phone like this has allowed me to transfer files between my computer and my phone; I'm able to get my music onto my phone, and my photos onto my computer, for example. For some reason, this has stopped working. My phone still charges its battery when connected to the computer, but neither the computer nor the phone recognized that they are connected. Is there something I can do to get the phone and the computer to detect each other? I don't know how to fix this, and it's more than a little frustrating. Any help would be greatly appreciated.

• Can I publish my game code under GPL? How? What about an engine?

  - by Bane

  I made a game, and I am currently making a game engine. I want them both to be completely free and open source. What license should I choose? I was reading a bit on GPL, but that seems to be more suited for system code and libraries, AFAIK, as it doesn't permit the use of code for proprietorial software - which, in turn, implies that the code can be used in the first place. I can see that, obviously, game engines can be considered libraries, and therefor be used, but what about game code? Is there an alternative to GPL?

• System Requirement Checking

  - by gl3829

  I am working on a game and want to strengthen its requirement checking to ensure that it can run successfully. Therefore, I am looking for information on what is useful to check before starting the game. As a simple example, Why check for a specific amount of memory? Should I as a game developer ensure a minimum amount of memory? I feel this information is usually skipped in many books and resources but is critical to be able to deliver a game that will run on many machines. I would appreciate if you answered with what you check in the system, why you check it and if you have a good resource about it, please include. Just to be a bit more specific, I'm developing in Windows.

• Setting up fastcgi on an Ubunutu server (socket file permissions issue)

  - by gray alien

  I am trying to set up mod_fcgid on my server. Part of the requirement is that Apache needs to create a socket file for mod_fcgid. I specified the folder for Apache to write the socket data to: /var/run/apache2/fcgid I then specified this file in my fcgid.conf file as follows: SocketPath /var/run/apache2/fcgid/sock I then changed the owner of the folder to www-data (the apache user) and gave the owner full permissions to the folder and its contents. I was able to run my test fcgi app then. When I rebooted the machine, y fastcgi app no longer worked. After some investigation, I found that ownership of /var/run/apache2/fcgid has been reset to root, and with permission reset to 700 I have the following questions: Is there something specific about the /var/run folder? why is the permissions being reset after a reboot? Should I move my socket file to another location (in case root automatically takes ownership of contents in this folder for security reasons?) I am running Ubuntu 10.0.4 LTS 64 bit

• Shared memory multiprocesses

  - by poly

  I'm building an multi processes application and I need to save session ID, the sessions ID is 32 bit, and of course it can't be used twice in its lifetime, I'm currently using DB that saves all the ID in a table, and I do the following, ID table is (int key, char used(1)) //1 is used, 0 is not 1. lock table 2. get one key for one sessions 3. update used field in it to used 4. unlock After the session is finished the process use below to free key, 1. lock table 2. update used field in it to not used 4. unlock I'm really wondering whether this is a good/fast implementation. and please note it's multi processes application.

• Silverlight 4 enables Authorization header modification

  A little bit of hidden gem in the Silverlight 4 release is the ability to modify the Authorization header in network calls. For most, the sheer ability to leverage network credentials in the networking stack will be enough. But there are times when you may be working with an API that requires something other than basic authentication, but uses the Authorization HTTP header. The Details Basically you just set the header value. Hows that for details :-). Seriously though, heres a snippet of code:...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Why Gsettings isn't enough to reset my nautilus settings?

  - by berdario

  I'm trying to narrow down a bug (to eventually report it or give up if it'll turn out that resetting a simple setting will be enough to get rid of it) I noticed that with a brand new user the bug doesn't pop up so I tried to reset the config of my user's nautilus I renamed .config/nautilus I renamed .nautilus2 (strange name... why the 2?) and I did a gsettings reset-recursively org.gnome.nautilus strangely enough, it didn't work: I previously set up to use my home as the desktop folder, and now the key has correctly been resetted $gsettings get org.gnome.nautilus.preferences desktop-is-home-dir false and yet on my desktop I see the contents of my home folder (meaning that the settings have not been resetted) I know that with the transition to gtk3 there've been lots of changes (before I should've used gconf... but now there's dconf and gsettings), so there're quite a bit of question about nautilus... but these unfortunately now seem to be outdated

• Chessin's principles of RAS design

  - by user12608173

  In late 2001 I developed an internal talk on designing hardware for easier error injection, prevention, diagnosis, and correction. (This talk became the basis for my paper on injecting errors for fun and profit.) In that talk (but not in the paper), I articulated 10 principles of RAS design, which I list for you here: Protect everything Correct where you can Detect where you can't Where protection not feasible (e.g., ALUs), duplicate and compare Report everything; never throw away RAS information Allow non-destructive inspection (logging/scrubbing) Allow non-destructive alteration (injection) (that is, only change the bits you want changed, and leave everything else as is) Allow observation of all the bits as they are (logging) Allow alteration of any particular bit or combination of bits (injection) Document everything Of course, it isn't always feasible to follow these rules completely all the time, but I put them out there as a starting point.

• Black screen with blinking cursor after dual boot install 14.04

  - by chillstream

  I have just installed Ubuntu 14.04 on my toshiba laptop along side Windows 7. When the menu comes up to choose which OS to boot into, I can easily boot into Windows 7. I cannot successfully boot into Ubuntu. All I get is a blinking cursor on a black/purple screen. I attempted the nomodeset trick, which was a bit more successful. I got a screen with a lot of code, but then it stopped with a blinking cursor at the bottom and wouldn't load anymore. As a last resort, would returning my laptop to factory settings get rid of linux and the partitions made to the drive? I already did this to my laptop when it was just windows, which is why I thought I might as well try to add Ubuntu. But it's a lengthy process, and if it won't get rid of the partitions and ubuntu, I won't bother. I appreciate any help ~many thanks

• How do you learn to effectively use more than one framework

  - by LongTTH

  Someday, my leader told me that don't reinvent the wheels, use framework built-in classes. (with a serious mood) when I implement some algorithm has been supported by .NET fx. And seriously, I didn't know about these support before, cause this is the first time I work with .NET). So I have this questions. For example, for building an Web-App we have some ways: C# with ASP.NET framework Java with JavaEE (and friends like Struts, Spring v.v.) framework. PHP with Zend framework. ... It just takes about 1 months to learn language (C#, Java, PHP...), BUT learning to use a framework effectively takes you at least SOME YEARS working (to know every bit of code has been built-in). So, how do you learn to use effectively 2 (or more) frameworks? Any ideas are welcome!

• Best Graphics card (Setup) for three, high-res monitors attached to desktop

  - by nomrasco

  I have been looking around a little bit, but most of the discussions are about problems with already existing systems (particular graphics card and setup etc.). I would like to ask what would be the best option for me if I want to build powerful desktop with triple monitor setup. I have one Dell UltraSharp U2713HM (27 inches, 2560x1440) and I was thinking about getting two more. Would it be possible to have those three working with ubuntu (kubuntu) on any graphics card out there today? What is the best option if it comes to choosing particular model? Should I use proprietary drivers or some open sourced ones? I am not a gamer. I mostly develop on my machines and running some computational tasks, but I would rather like to spend some more money and have setup where I don't see any lags :) thank You very much in advance!

• Why can't I update to 11.04?

  - by user285982

  I am using Ubuntu 10.10 64 bit, and I can browse the internet fine. I am typing this using the machine.

• What are the challenges and benefits of writing games with a functional language?

  - by McMuttons

  While I know that functional languages aren't the most commonly used for game writing, there are a lot of benefits associate with them that seem like they would be interesting in any programming context. Especially the ease of parallelization I would think could be very useful as focus is moving toward more and more processors. Also, with F# as a new member of the .NET family, it can be used directly with XNA, for example, which lowers the threshold quite a bit, as opposed to going with LISP, Haskell, Erlang, etc. If anyone has experience writing games with functional code, what has turned out to be the positives and negatives? What was it suited for, what not? Edit: Finding it hard to decide that there's a single good answer for this, so it's probably better suited as a community wiki post.

• Question between aggregations, compositions, references (arrow) and simple link (nothing) relations within UML2 ?

  - by Rushino

  Hello, I have some questions regarding relations between aggregations, compositions, references (arrow) and simple link (nothing) relations within UML2 ? If A - B - C each have composition relationship. Are the root responsable of creation and destruction of the object B and C ? What aggregations have that the simple link or references doesn't ? What make them different ? Thanks. Edit: The question was a bit unclear and not objective. I edited it.

• New Window Via JavaScript Clears Parent

  - by Bunch

  This is not a new item at all but I came across it recently. For an app I had been using some JavaScript like: javascript:window.open(someurl.aspx here) to open a new window via a button. That bit of code had been working great in several other apps. Then in one app that same code decided to open the new window correctly while clearing the parent of everything but [object]. The fix ended up being simple, change the javascript to: javascript:void(window.open(someurl.aspx here); Then it worked like I thought it should. Tags: ASP.Net, JavaScript

• Where Are Multiple JUnit Test Methods Typically Placed in Code?

  - by Thunderforge

  I've just read the Vogella JUnit tutorial and found it very helpful in understanding how to use JUnit. However, I'm a bit confused about what the convention is for placing multiple test methods in code. The tutorial only places one test method in a class, then describes how you can use a test suite to group multiple test classes together. Does this mean that it's common practice for each test class to only have one test method and then test suites are used to chain them together? Or was that just unintended and instead common practice is to put multiple test methods in a class?

• Second click on a launcher icon with more than one window open doesn't do a scale of that application

  - by Eastsun

  In unity, if I click an icon in the launcher with multiple windows open it doesn't show me all open windows for that application. However, this works in unity2d. I known there have a same question asked before: here! But I think my condition is not as same as the previous question. ubuntu 12.04 64-bit unity 5.16.0 kernel linux 3.2.0-33-generic gnome 3.4.2 Edit I just find a interest thing: There are four workspace, label it as A, B, C, D. If I firstly open two windows of firefox in A, as I mentioned above, second click on the firefox icon does nothing. But after I open a window of firefox in B, the second click on the firefox icon in workspace A magically works!! And then, I open two terminal in workspace C, second click doesnot work until I open another terminal window in D. So, it seems that the second click only work if the application be opened more than one workspace.

• How To Sideload Modern Apps on Windows 8

  - by Chris Hoffman

  The average Windows 8 user can only download apps that Microsoft has approved from the Windows Store. Windows 8 offers two ways to sideload unapproved apps, which are intended for developers and businesses with internal apps. These methods cannot be used by the average geek to install unapproved apps from the web. Windows 8’s new interface takes the Apple iOS approach of forbidding unapproved software, not the Android approach of allowing all users to enable sideloading. Note: This only applies to Modern apps in the new Windows 8 interface, not on the desktop. Windows desktop applications can be installed normally. However, you can’t install any desktop applications on devices running Windows RT. Why Does 64-Bit Windows Need a Separate “Program Files (x86)” Folder?

• Cannot connect to wifi after downloading 12.04, repeated prompts for password

  - by Daytown3487

  I have had this OS for a little bit but this is my first upgrade and my first issue I am trying to deal with without my buddy who got my on Ubuntu in the first place (who is on the other side of the country.) I am running an IBM Lenovo T400 Thinkpad that had 11.10 on it and worked flawless. I upgraded to 12.04 a few weeks back and I have not been able to connect to the wifi in my home or anywhere for that matter. I have been trying to mess with it through reading the forums and am not quite sure what my problem is. I am running off of Fios Internet and the wifi keep disconnecting and prompts me to retype the password for reconnecting. If you guys could give me a step by step process of how I should go about fixing this I would GREATLY appreciate it!

• How to choose a good namespace name? [Linguistically]

  - by Kees C. Bakker

  English in not my native language, therefore it is a little more difficult to pick a good name for a namespace. One example to make you see my problem a bit better: We have a set of classes that have to do with the way a company is organized (we can create organizational charts with it). Currently the namespace is CFW.CoreSystem.Organizational. Is this a good name? What is linguistically the best way to name a namespace? (CFW.CoreSystem.Configuration is better than CFW.CoreSystem.Configurables). [Moved it from StackOverflow]

• Two users sharing the same computer

  - by Pitto

  I need to share my pc with a friend of mine living in India. His pc is a p4 and he needs a bit of horsepower for calculation. Since I have an i5 I thought to let him vnc and use it but this would not allow me to use the computer at the same time. Is there a way to use the computer at the same time with different users? I've read Xorg is able to do this but I am not sure is the best solution nor I can implement it. We have Ubuntu 12.04 64bit on the i5 side and Ubuntu 12.04 32bit on the p4 side. Thank you for your kind help.
