C# has been standardized by ECMA & ISO since early 2000, made open source (I'm a F/LOSS user) by Microsoft, & runs on GNU/Linux platform via Mono implementation. .NET, ASP.NET MVC, Web API, and Web Pages have just been released as open source too. This gives C# and .NET platform a wider area to develop applications (giving a challenge to Java supremacy). Swift is relatively new language but intended as replacement for Objective-C, the language used for Apple's OS X & iOS (the future ahead is huge, right?) The development tools are hardly accessible since one will have to work on OS X and are often expensive, but sooner or later non-OS X/iOS developers would enjoy the same as the language itself is open source. It's inevitable to learn things like HTML, CSS, JavaScript/jQuery since they are standards. So if both, that's too much. What do you think?

Open source community has been successfully for having alternative to Microsoft Office through OpenOffice and its fork version, LibreOffice. But, don't you know that there is another office suites player around, not just in Windows but also in Linux system? Yes. It's Kingsoft Office . To be honest, in my own view, this is very close to Microsoft both its look & theme and its functionalities. It has even more features similar to OO/LO, which I believe Kingsoft borrowed from OpenOffice/LibreOffice. However, unlike OpenOffice/LibreOffice, Kingsoft only includes three applications - Writer, Spreadsheets and Presentations. One good thing is that it has editions for Android and iOS. I must say that these applications by far are the closest compatible of Microsoft Offce documents for word processing, spreadsheets and presentations. Please take a while to view the following screenshots.    

Coming across with Firefox OS Simulator, I installed Firefox OS Simulator from the roster of Firefox add-ons. Just click Add to Firefox button on https://addons.mozilla.org/en-US/firefox/addon/firefox-os-simulator/. Firefox will install the Simulator without restarting Firefox browser. After installation, dashboard will open on separate window. I tried running the simulator by clicking Stopped/Running button on the left of the window; it will open a small size-window, the simulator. I tried browsing my Facebook account by clicking browser button on the taskbar (globe icon); I entered m.facebook.com in URL address and did login. That's it!

This is a developing post. Ever since, Firefox is my browser. Sometimes, I would use Chrome to open my other online account, Yahoo! Mail, if my primary account is already opened with Firefox. I have also been using Firefox when developing PHP Web applications or working with WordPress CMS on localhost. I have never found any thing somewhat deviating from what I was expecting from Web pages. They all work fine; I mean Firefox renders them properly. But, there was a time I opened my WordPress Website which I have been developing in Firefox on Chrome Web browser. Oh, Chrome rendered it other way. You know how Chrome rendered it? Please see my screenshots below. I also opened my site on Opera and Safari Web browsers to see if they have the same rendition with Firefox of Chrome. Web browsers included: Firefox 21.0 Chrome 28.0.1500.11 Safari 5.1.7 Opera 12.15 Oppps! I do not intend to declare that my Firefox is the best browser out of this comparison, however, to my satisfaction

Android is a big hit among smartphones, phablets, tablet, and why in desktop or notebook? So here, I'm gonna show you how to run the livecd of Android OS: 1. Download Android OS from: http://code.google.com/p/live-android/downloads/list 2. Two files need to be downloaded. One which file extension is .001 and the other one is .002; I downloaded the following: liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 3. Since these files are splitted, you need to join them. Download HJ-Split from www.hjsplit.org. Extract and run hjsplit.exe. Click 'Join' button and a new window will open; to join a set files (.001 and 002), first open the .001 file using the 'Input File' buttons. Other files (.002, .003, etc.) which are in the directory will be found automatically. Then click Start button and wait few minutes until finished. This should produce file something like liveandroidv0.3.iso   * If you are running GNU/Linux OS, you can simply run the following comm
