Switching iPhone visibility in Windows 10

-
Image
It's been now several times that I plugged in my iPhone to download my pictures into Lightroom and the device is not showing up on "My Computer". When launching iTunes the iPhone is there, fully operational, sync-able, etc. I've got the latest iTunes, the latest update on the phone, everything! What's going on? The iPhone simply seems to either operate as an MTP USB Device which makes it visible under "My Computer" or as an Apple Mobile Device which makes it visible in iTunes. Switching between the two modes is simple: iPhone working in iTunes, not visible in "My Computer" Device Manager -> Portable Devices -> right-click on Apple iPhone -> Update Driver Software... -> Browse my computer for driver software ->  Let me pick from a list of device drivers on my computer -> MTP USB Device -> click Next. iPhone visible in "My Computer", not visible in iTunes Device Manager -> Universal Serial Bus control...

Installation of Mint 17.1 Cinnamon on VMWare

-
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...

GetDIBits vs. Scanline vs. Pixels[] in Delphi Bitmaps

-
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...
