I've been always wanting to sit down one day and solve this problem; test the speed of manipulating pixels on a Bitmap using the three options: - the convenient but understandably slow Pixels[], - the "interesting" Scanline property and - the Windows API GetDIBits and SetDIBits. I have been traditionally using Pixels for quick work and the Get/SetDIBits for low-level pixel manipulation such as the filters used in ToolBox . Never really used the Scanline property in anger, I was always thinking, DIBits "had" to be quicker. Little I knew... I have been experimenting with two tools that I've written and never released to the public domain. The first is the BMPCreator which I wrote in order to create 256-level grayscale bitmaps, the other is the IconCreator which uses a grayscale bitmap and applies color maps to it, giving you the ability to create different colored versions of the same icon (like in my database visualization tool VirtualTreeNavigator ). Yesterd...
It's been 2.5 years since I posted an installation guide of installing Ubuntu 12.10 on VMWare Workstation but the release of Linux Mint 17.1 has prompted me to write an updated guide. This is the third of my guides, acting mostly as a memo for a quick install of new distros on VMWare, my first one written in 2009 ( Linux on VMWare with later additions of other posts full of little hints and reminders (e.g. fonts, keymaps)). Ingredients Please note that these instructions work for most distros, although this post focuses on Mint 17.1 A downloaded ISO image of your favourite distro ( Mint , Mint LMDE , Ubuntu , Debian ) A newly created virtual machine with 2-8GB of RAM, a 40-60GB disk and a couple of CPU cores. Installation Mount the ISO image to your VM's optical drive and boot it up, then follow the instructions to install your distro selecting your preferences (timezone, keyboard layout, etc.). For accessing your VM via ssh from your host, it helps if your Lin...
For a few years now I use Windows, Linux, OS X daily. For years, I've been looking into a language/framework/product that will allow me to build (desktop) applications that can run on all of these OS's. I've looked into QT , PyQT , Java Swing and others. I've looked into the cloud , PaaS , web applications but I couldn't find something that I liked. Of course, HTML5 has gained a lot of momentum and I've been following it from the very first day, so I was "double" happy when I found out about the Chrome Packaged Apps that look and behave like desktop apps, they can however live perfectly in the cloud and are built purely with web technologies. The fact they can run on my Chromebook too, is the cherry on top. Hello World! No time to lose, I jumped into the proverbial Hello World app, which run on my stable Chrome 27.0.1448.0 without a glitch. You have to follow instructions on the previous link to enable the Experimental Extension APIs on chro...
