• Custom vs. browser-native scrollbars

  - by vemv

  Including customizable, JavaScript-based scrollbars (and scrolling functionality in general, i.e. bind the control to the mouse scroll wheel) in your webapp can be a great temptation. However all solutions I could find were developed by individuals (which can equal lack of formal or future support). In addition I fail to remember any mainstream site using them. In my particular case, no-JavaScript or IE6/odd-browser environments are not intended to be supported. Should custom scrollbars be avoided nowadays? If not, what's the best option one can choose?

• Where are the values of java.library.path being set?

  - by lmestre

  This one could be a WebLogic Server question, but this post is general for any java environment.We were getting  at the very beginning  java library path something like this: /home/lmestre/jdk1.6/jre/lib/amd64/server:/home/lmestre/jdk1.6/jre/lib/amd64:/home/lmestre/jdk1.6/jre/../lib/amd64So, the question was: Where WebLogic Server is setting java.library.path?I never found the answer, so why don't we try to try to answerWhere the JVM is setting java.library.path?public class LibraryPathPrinter {   public static void main(String[] args) {       String javaLibraryPath= System.getProperty("java.library.path");       System.out.println("java.library.path "+javaLibraryPath );   }}after a simplejavac LibraryPathPrinter.javaand then an easyjava LibraryPathPrintervoila!The program printed something like thisjava.library.path  /home/lmestre/jdk1.6/jre/lib/amd64/server:/home/lmestre/jdk1.6/jre/lib/amd64:/home/lmestre/jdk1.6/jre/../lib/amd64So the JVM was the culprit.Enjoy!

• Best stats tool for cross-domain tracking

  - by kidbrax

  We build a webapp that allows users to run the app under their own subdomain. So we run the app under search.domainX.com, search.domainY.com and so on. They each have their own Google Analytics to track individual stats. But we want to know what general traffic for all clients of our app. So we want to know stuff like "among all our clients we had x number of views." What is the best way tool to track that sort of thing.

• Are there any reliable solutions for annotations/reflection/code-metadata in C?

  - by dukeofgaming

  Not all languages support java-like annotations or C#-like attributes or code metadata in general, however that doesn't mean it is not possible to have in languages that don't have this. An example is PHP with Stubbles and the Doctrine annotation library. My question is, is there anything like this for C?, or are there any reliable ways of doing reflection with extended code metadata in C? Ideally, I'm looking for something that reads javadoc-like comments. Edit: The reason for me *needing* as opposed to just wanting, is that I need to generate C code and code-metadata from a database, as well as being able to edit that metadada and update the database. The volume of the work (~15,000 variables/structures/functions to generate from this database) justifies the solution.

• Using a GPL licensed library in a commercial app

  - by user577616

  I develop an android application and in my app I use a libary (jar) that I download from the internet. This jar is open-source under the "GNU General Public License v2". I tried to read the text of the license but had difficulty understanding it. My question is: can I use this libary without changing nothing in the jar in a commercial application? I will be making profit from selling my app which uses this GPL-ed .jar file. If possible, I would like to avoid converting my application to open-source.

• How do I install drivers for graphics and sound?

  - by Sid

  I recently shifted to Ubuntu 12.04 from windows 7. I completely removed Windows and then installed Ubuntu. However, I can't find a way to download and install drivers for my video and audio hardware like I used to be able to do in Windows. Could someone please explain to me how software and drivers, in general, are installed on Ubuntu. Is installing through 'Ubuntu Software Center' the only way to install them? My laptop model is: Dell Inspiron 14 N4010 (i5/4gb/500gb). Kindly help. Thanks in advance.

• category title and affect on SEO and ranking [closed]

  - by Mark

  We are working on a jobs and skills website (similiar to Skill Pages) and are deciding on the names of categories. Rather than having loads of categories and sub-categories like, for example, Builder, Electrician, Carpenter etc, we would like to have more general and easier on the eye category names. So for example we have House, Computer, Education, Art etc. So a builder would be in category House and a few others. Will this style negatively effect our SEO and ranking? And if so, should we abandon and go back to traditional categories and sub-categories?

• Advice on approaching a significant rearrangement/refactoring?

  - by Prog

  I'm working on an application (hobby project, solo programmer, small-medium size), and I have recently redesigned a significant part of it. The program already works in it's current state, but I decided to reimplement things to improve the OO design. I'm about to implement this new design by refactoring a big part of the application. Thing is I'm not sure where to start. Obviously, by the nature of a rearrangement, the moment you change one part of the program several other parts (at least temporarily) break. So it's a little 'scary' to rearrange something in a piece of software that already works. I'm asking for advice or some general guidelines: how should I approach a significant refactoring? When you approach rearranging large parts of your application, where do you start? Note that I'm interested only in re-arranging the high-level structure of the app. I have no intention of rewriting local algorithms.

• Top X tips to code & debug efficiently [closed]

  - by user1510230

  I'm starting a big Java project and I wanted to have some advices that could benefit us all. What are the X (X could be 5 / 10 / ... or even 100 :) most important tips to code and debug efficiently in general (and in particular with java / javascript) ? I'll start with some basic ones : Use functions everytime a portion of code is used more than twice. Try not to code features with more than 15 lines of code in one shot. Rather write 5 lines of code then check if they work correctly then write 5 more... and so on start with the outcome of the function and then code it backwards (bottom-top approach) ... Thanks everybody

• GPU optimization question: pre-computed or procedural?

  - by Jay

  Good morning, I'm learning shader program and need some general direction. I want to add noise to my laser beam (like this). Which is the best way to handle it? I could pre-compute an image and pass it to the shader. I could then use the image to change the opacity and easily animate the smoke by changing the offset of the texture lookup. I could also generate noise in the shader and do the same thing the texture was used for. Is it generally better to avoid I/O to the graphics card or the opposite? Thanks!

• How to make Ubuntu 14.04 run with less lag?

  - by King Shimkus

  I recently updated from Ubuntu 12.04 LTS to 14.04 LTS and for the first time it worked! However, whenever I move my mouse over an application icon on the unity shell, the animation takes forever to show me what the name of the application is ( A.k.a the tooltip ). The same happens with menus and sub-menus. Other than that, it is overall in general, slow. I just want to know if there are any tips to fix this or make my system faster. This is what it says when I type in glxinfo | grep renderer: GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer, OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.4, 128 bits) Output of lspci | grep VGA: 00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)

• How do I share common classes between windows forms and web applications using C#?

  - by earthdog

  In our environment we have multiple ERP servers plus data that are coming from multiple sources. I need to create a development roadmap for the coming years as it is obvious that side applications will be needed for many things. The choice is that the development will occur with Microsoft technologies. This means that I will be building either web apps (MVC, web forms e.t.c) or standard windows forms applications. The thing here is that I will be creating classes that will encapsulate the business logic that I want to apply to the different projects. What I thought so far: 1) Create class libraries dlls containing the required logic 2) Reuse these libs in my apps. But what about the web apps? Should I use the dlls directly or I should encapsulate them in web services and consume the web services in web apps? In general I would like to find out how should I build my strategy.

• Even distribution through a chain of resources

  - by ClosetGeek

  I'm working on an algorithm which routes tasks through a chain of distributed resources based on a hash (or random number). For example, say you have 10 gateways into a service which distribute tasks to 1000 handlers through 100 queues. 10,000 connected clients are expected to be connected to gateways at any given time (numbers are very general to keep it simple). Thats 10,000 clients 10 gateways (producers) 100 queues 1000 workers/handlers (consumers) The flow of each task is client-gateway-queue-worker Each client will have it's own hash/number which is used to route each task from the client to the same worker each time, with each task going through the same gateway and queue each time. Yet the algorithm handles distribution evenly, meaning each gateway, queue, and worker will have an even workload. My question is what exactly would this be called? Does such a thing already exist? This started off as a DHT, but I realized that DHTs can't do exactly what I need, so I started from scratch.

• GPL exception that allows linking to free licenses only?

  - by fNek

  There is the GPL license and the linking exception which allows closed-source programs to use the program as a library. There is also the slightly more restrictive LGPL (more restrictive than GPL with exception since it requires that the user can change the library in the resulting project, etc.). And there is the Cygwin exception that allows linking to open source programs. I see clear advantages: Open-Source programs may use the library. People may use these programs for closed-source programs, but then they lose the permission to use the (GPL) library. However, there are two things I don't like about the Cygwin exception: - Its legal status is disputed - I keep hearing that it is basically worthless - It requires certification by the OSI, I would rather have certification by FSF Is there an exception to the GNU General Public License that meets my requirements?

• Progressing past CRUD applications in PHP?

  - by Anonymous -

  I've been programming in PHP for about a year and am at the following stage: Have a good 'feel' for the language Can create CRUD applications competently Can utilize an MVC structure to allow for future expansion of code Using the points listed above, I've created a number of my own applications for practise - including but not limited to; a forum, social network etc. My question may be a little vague but should hopefully be answerable. I feel as though there isn't anything else I would need to know about PHP to allow me to create websites, though I'm sure I'm wrong. What advanced/complex PHP topics could I look at that have a real-world use and will allow me to enhance both my skill as a programmer and applications in general? Recently I've looked a lot more at javascript/jQuery allowing me to give my applications a richer user interface which has been a great learning experience and proving very useful.

• Building a website, wondering how to add news to it? Details inside. [closed]

  - by Robolisk

  On the home page of my website, I'd like to add a "news" kind section, where I can add blogs and such. Now from my understanding if this was all done in hard coding I'd have to go into the code just to add stuff to it. I've looked at things like drupal and I get how those work, but I how would I be able to add this to my site? The same kind of concept? Also, one more thing, what does inc operating php into a website offer? like better looks or general preformence? I don't understand this. Excuse my grammar/spelling. (: And thank you for taking the time to read this.

• Issue with permanent redirect implementation

  I have a tricky problem related to 301 redirections I badly need help with. I tried to implement these via .htaccess, but ran into trouble. The start of my .htaccess looks like this: SetEnv PHP_VER 5 Options +FollowSymlinks RewriteEngine on # Redirect non-www to www RewriteCond %{HTTP_HOST} !^(www\.|$) [NC] RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L] #--- GENERAL --- RewriteRule ^index\.html$ index.php [L] ... When I try to put a permanent redirect to index.php by adding R=301 in the square brackets, I get a 404, and I have no idea where the error comes from.

• Screen tearing (very noticable during video playback) with HD3000 AND HD Radeon 6630m

  - by NilRecurring

  I did not have this issue with Ubuntu 11.10. Well, to be clear, I did, but it was easily remedied with compiz workarounds. I have tried both the propriety and open source ati drivers, and the intel HD 3000 (as far as I know) should be part of the Kernel already. So I am pretty much 100% stumped given my general lack of Linux knowledge. I really enjoy this OS, would hate to have to return to Windows (read: HATE) because of something as trivial as video playback. Some details: Lenovo Thinkpad Edge e520 Intel HD 3000/AMD HD Radeon 6630m Ubuntu 12.04 64bit.
