When I was busy with one of my projects, I decided to make a PCB. You can say that I could use a breadboard, but I had to make a lot of boards and I didn't want to spend a lot of time with the soldering iron, so my decision was quite predictable: I decided to order a PCB from the factory and place the order at the pretty famous chinese Seeed Studio and I wasn't disappointed with the result. It was pretty easy to prepare the files for the production and place the order.

Accidentally I found one pretty interesting chip from FTDI: FT4232HL. This manufacturer is quite well known by it's USB<=>Serial solutions and their "driver" war against chinese clones. Nevertheless, this problem has a solution, so I will not go into the details.

FT4232HL is a 4-channel USB<=>Serial converter, which also supports I²C, GPIO and SPI modes. These features are the subject of the separate article, by default device works in the USB<=>Serial mode, which is more than enough for me.

Em::Blocks - IDE for ARM Cortex.

Once upon a time, when I was completely tired with slow CooCox and other Eclipse based IDEs, I've tried to search for a good alternative. Some of my projects are open-source, and it means that anyone, who have downloaded my project, should be able to build it without any license fees. Abilities of "light" versions of commercial IDEs were lower than I expected, so my search was limited only to free alternatives. Accidentally I found Em::Blocks.

Creating symbolic links in cPanel

Once upon a time I had a problem with creating symbolic links in cPanel. My goal was to make two websites copies with one shared "Uploads" folder.

Native website engine did not have such feature, htaccess did not work in this case, so my decision was a little tricky, but very easy.

Replacement of xdotool: xmacro

For those who don't know: xdotool - it's a small console program, which can emulate keyboard and mouse input. I used it together with irexec and lirc to control my computer. xdotool I used only to control sound volume by emulating multimedia keystrokes. Unfortunately, I found an unpleasant bug. Starting from some unknown version (I don't know the exact number, because I notice this behavior much later) xdotool refused to work correctly with non-english keyboard layouts. Moreover, after I switched to Debian, it started to hang for second before execute command.

I did not have time to deeply investigate this problem, but accidentally I found a great alternative. Its name is xmacro.
