I started seeing a black spot or splotch on pictures previewed on the LCD screen of my digital camera (Fuji FinePix F30). This was ruining all my pictures since the white or light-colored portions of my photographs would show this black splotch. It appears that this is due to dust on the camera’s sensor and [...]
One day, I decided that I wanted to get into stock photography. This blog post inspired me to consider this. So I went through the hundreds of photographs I had taken over the last few years and picked out what I thought were a few great photographs. Then I signed up on iStockPhoto and uploaded [...]
` The iPhone and the iPad (as also the Motorola Droid and all the other Smartphones with their fancy virtual keyboards on the touch screen) do not support all possible keys in their virtual keyboards. A case in point is the backtick character. This makes it a problem when you need to enter the character [...]
Though in general it is true that you should simply leave C code optimization to the compiler, it sometimes is useful to provide hints to the compiler.

I use the excellent ConnectBot SSH client on my Motorola Droid to SSH into Linux/Unix boxen. Subsequently, I make the mistake of using Vim.

Then enter or exit the insert-mode as many times as you wish, editing text using the keyboard. All the time, vim will keep recording all your [...]

Text files created on Microsoft Windows usually use a combination of Carriage-Return and New-Line (CR-LF or \r\n) to separate lines. When such text files are opened in Windows using Vim (usually in the Unix mode), the Carriage-Return’s will show up in the file as ^M (CTRL-M) and can be annoying specially when you are going [...]
“How much did you have to drink?”…”More than a little, less than enough”. Dialogue on Psych on USA. Nice. Either that or I am sleepy. It’s 11.22pm.
