Could you guys please how I can do this search very fast and list the results in a efficient way. If you guys know any methods and technologies pls do advice.

• personality problem while learning web development [closed]

  - by Lazeera

  I work a lecturer and when I go home I find a lot of free time. The problem is that I spend most of my time in learning about web development. I don't go outside and don't meet people, I'm only in front of the screen drinking 4 cups of coffee (per day) and trying to learn many technologies related to web development. In the last, I don't learn things very well because I'm in a hurry. I know this place is for asking about programming but I want to learn from your experience regarding learning. How do you learn? How many hours do you spend in leaning a day? How can I organize my time so I can learn well and easily?

• Developing applications for iPhone, BlackBerry and J2ME in ASP.Net

  Hi, I would like to introduce you a new mobile application framework iPFaces for developing native, form-oriented applications. The aim of the solution is to screen the programmer completely out from the mobile platform itself, and transfer the entire application logic to the central application server level. Developers with experience with one of the supported Web technologies (ASP.Net, Java, and PHP) may start working with iPFaces virtually immediately. For more information, see the project...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• If I am developing a hosted payments page, what should the infrastructure look like?

  - by marcamillion

  If I am not storing credit card info, do I have to be concerned with PCI-compliance? I will be using a payment processor with a bank in my country. Literally just taking the credit card info and passing it to the gateway and processor. I would love to get an idea of the various technologies I might need to consider from an software architectural point of view. What are the best practices in terms of accepting credit cards and reducing fraud risk on my end? I will be creating the app in Rails.

• Managed servers getting down regularly by Node Manager. WAD?

  - by csoto

  Recently I have been working on a service request where several instances were running, and several technologies were being used, including SOA, BAM, BPEL and others. At a first glance, this may seem to be a Node Manager problem. But on this situation, the problem was at JMS - Persistent Store level. Node Manager can automatically restart Managed Servers that have the "failed" health state, or have shut down unexpectedly due to a system crash or reboot. As a matter of fact, from the provided log files it was clear that the instance was becoming unhealthy because of a persist6ent Store problem. So finally, the problem here was not with Node Manager as it was working as designed, and the restart was being caused by the Persistent Store. After this Persistent Store problem was fixed, everuthing went fine. This particular issue that I worked was on an Exalogic machine, but note that this may happen on any hardware running Weblogic.

• PowerXpress error with Driver Catalyst. How can I fix it?

  - by J03Bukowski

  I have install Ubuntu 11.10 64bit on my Hp Dv6-3150el. My Notebook has two graphics cards: lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Madison [AMD Radeon HD 5000M Series] I tried to install the proprietary graphics drivers ''fglrx'' available in "Additional Drivers", which does not give me 3D graphics acceleration (and I can't install those post-release). Then I can try to download and install from the website (I tried the version that Catalyst 11.8 11.12). The installation goes perfectly (I followed this guide and others), except that when I configure Xorg.conf file: sudo aticonfig --initial PowerXpress error: Cannot stat '/usr/lib64/fglrx': No such file or directory Failed to initialize libglx for discrete GPU

• What Languages are mostly understood "intuitively" and could benefit from a more formal learning approach?

  - by keppla

  In a presentation, i stumbled upon the Statement "JavaScript is a Language everybody uses, yet nearly noone seems to find it neccessary to learn how it works". And indeed, not many of the programmers i know could explain javascript's prototype concept, or why functions need to be 'bound' to this. CSS seems to be another example of this behaviour: everyone knows how to put a 'class' to an element, and to write a style .myclass { ... }, but only a few even know of margin-collapse. My question is: are there more of those languages, technologies, concepts, that are so prevalent that we dont even notice them as something worth learning while we use them?

• Technical website - Should I assume that my visitors will use a modern browser?

  - by marco-fiset

  I am in the process of creating my own website, which will include a technical blog. I want to build my website using modern technologies such as HTML5 and CSS3. Since my website will be targetted at programmers and mostly tech-savvy users, should I take for granted that these people will be using a modern browser? Or should I make my site compatible with older browsers just in case? I don't want to go through the pain of adapting my website to be compatible with browsers I assume won't be used.

• Is it viable to become a contract programmer straight out of college?

  - by M G

  I have a Bachelor of Science in Computer Science and four months research experience designing and implementing a research project. I realize this is highly dependent on my skill set - which includes C, C++, Java, Python, and SQL. I feel I have an advantage in two ways: I am young and am not afraid to work overtime. I am willing to take lower pay to gather a client base/experience, and work nights/weekends to get a few projects under my belt. This may be cliche, but I feel that I can learn new technologies quicker than most. At the very least, I am not a slow study. With this being said, is it viable for me to become a contract programmer? Or do I need the 10+ year skill set that most contractors bring to the table?

• Dell L501X Display Port Screen issue

  - by jdflorezPA

  I got a Dell XPS L501X with a mini display port to VGA connector for my External Screen. On Displays it shows me: Acer Technologies 24" (which is the monitor) but only lets me up to 1024x768 resolution (The native resolution of this monitor is 1920x1200). I tried adding a new mode with xrandr, but when I applied it, it reverted back to 1024x768. As far as I know, the display port is controlled by the Intel card, right? Any ideas or suggestions would be appreciated. Thanks Using Ubuntu 11.10 32bit

• 3d js map rendering

  - by gotha

  In the past I've done a 2D tile map using HTML, CSS and Javascript. Now I have the task of creating a 3D version using the same technologies - think of it like a space map where all planets have x/y/z positions. Currently, I have no idea to do this. Is there an existing library or something I can modify to do my job? If not, what method of rendering the map should I use? It needs to be as browser independent as possible, so I can't use webgl, flash or canvas. I'm considering plain JS & HTML or SVG (using Raphael for compatibility).

• « Google pourrait ne plus exister dans cinq ans », la faute à Siri d'Apple d'après un analyste financier américain. Vraiment ?

  « Google pourrait ne plus exister dans 5 ans » La faute à Siri d'Apple d'après un analyste américain. Vraiment ? Les derniers mauvais résultats financiers de Google ? surtout plombés par Motorola ? n'ont pas tardé à susciter des vocations d'oracles alarmistes. Parmi ces nouveaux omniscients adeptes du catastrophisme, Eric Jackson, le créateur du fonds d'investissement Ironfire Capital spécialisé dans les technologies, ne fait pas dans la nuance. « Google pourrait disparaitre d'ici 5 à 8 ans comme Yahoo !, qui était le roi du search, a disparu », a-t-il ainsi déclaré à la chaîne financière CNBC. Cette disparition viendrait des usages mobiles. Les utilisateurs voudrai...

• Is client-side HTML5/JavaScript too lame after you've worked on server-side C++/Java?

  - by stackoverflowuser2010

  I'm an experienced C++/C/Java/C# research software engineer and have worked on large-scale server systems, including huge map-reduce and database systems. Now I've been offered a new job working with client-side mobile technologies involving Javascript and HTML5 as well as some very minor native iPhone and Android programming. So, question: If you've ever made this kind of jump, did you find find Javascript/HTML too lame after you've been working on "hard-core" C++ and server systems? Did you find it challenging? Did you get bored?

• Frameworks for targetting multiple environments

  - by Werlang

  What should drive the decision behind doing development upon one or more than one framework? For instance, an ERP is (mostly) run on a Windows station. It leverages full access to device's resources, like printers, barcode readers, fingerprint readers and the like. It's usually more responsive and easier do develop with. That being said, some parts of it must be accessed exclusively in self-service mode, by enterprise's customers, suppliers and partners. This could be accomplished with smartphones, tablets, or even desktops running a web browser. What are the economics behind that? Should two team be kept, each one doing work upon its own framework? Or the most permissive framework should be chosen? Should I care something other than HTML technologies? Should I consider native technology for each device?

• Browser game in JSP? [closed]

  - by Constant

  I want to develop a browser-game (like ogame, travian) and I have some doubts in which technologies should I use. I was thinking in a server-side in JSP,Java and a client-side in HTML (or HTML5 if I learn to give it good use). Do you think my choices are right? I would like to make a board where many players could move simultaneously between tiles or squares. Do you think is possible in JSP or I should start with other language? Any suggestion aprecciated, and apologies for my english. Thank you! Regards!
