Nothing to see here, folks… These are just some notes I wrote down for myself, in case I’ll ever want to repeat this mess. Microsoft Visual Studio 2003 was used for developing the C++ class as well as the setup project. For testing, IE 6 was used. A button running a script or executable The [...]
Introduction An Israeli website, “Kama Kesef” (כמה כסף in Hebrew, meaning “how much money”) is a neat web calculator telling how much to give as a money present in weddings and other events. When I realized that I’m far from being the only one using it to decide what sum to write down on the [...]
Before anything: Recent distros come with packaged utilities for encrypting a disk, partition, USB stick or whatever block device. This little cookbook is for those who are not that lucky, or prefer to do things with their bare hands. If you’re not familiar with using loop devices, I suggest playing a bit with them before [...]
I warmly recommend reading the comments at the bottom of this page, many of which go against my point. While I still stand behind every word I said, in particular for web applications (which I believe is the vast majority of MySQL use), the comments below make some valid points, and single out cases where [...]
Take a close look on the Verilog code below. This is a plainly-written synchronous ROM. Do you see anything wrong with it? (Spoiler: There is nothing wrong with it. Not that I know of) module coeffs ( clk, en, addr, data ); input clk, en; input [9:0] addr; [...]
When I first discovered that there is both BLOB and TEXT in databases, I was puzzled. They occupy the same amount of disk space, and the database doesn’t alter the data itself anyhow. Why two? Of course, I followed the stream, and went for TEXT and VARCHAR for everything, since I don’t store binary data [...]
Some electronic imaging system dumped a 4:2:2 YCbCr raw image into a file. It’s a debug output. Now I wanted to see this image. GIMP doesn’t import that format. ImageMagick had the solution. It was as simple as convert -size 800x600 pal:ImageOut.raw ImageOut.bmp I don’t know why they picked the codename “pal” to represent 4:2:2 [...]
I reached that point, at which place and route sometimes met timing, and sometimes it didn’t. It was all a matter of playing with the placer cost table number. The FPGA guy’s gambling for lucky numbers. The ISE tool (Xilinx’ native IDE) supports an feature called Multi-Phase Place and Route (MPPR for short), which basically [...]
I love LaTeX. It’s my preferred tool whenever I need to write a document in English. But it had one little problem: The documents it generated, even though beautifully typeset, had an academic look. For someone who submits the documents to hitec companies, an engineering-like look was more appealing. So I wrote my own document [...]
Ehm.. This is really outdated Cinelerra has made a long way since this was written. So really, take this with a grain of salt. Making the Dyne::Bolic live CD feel at home Nest (under /dyne). 128 MB should be enough Dock Boot from hard disk Make a swap partition (if it exists, it will be [...]
