If you ever wanted to support an open-source project but you are not a programmer, here's one (of many possible) ways to help:
To quote from the announcement:
We’re hoping to build real subtitle support into Miro in the next couple months, but we need your help! So we’ve started a Kickstarter project to raise $1,000 to develop this feature for Miro on all three platforms: Windows, Mac, and Linux. Can you pledge to help make it happen? One of the great things about the Kickstarter model is that unless we can reach $1,000, your pledge won’t be charged.
(if you live in the United States, donations are tax deductible — we are a 501c3 non-profit)
There are 11 days left to make a pledge.

Here's some world music from the "Nour" album of Shiva in Exile. Enjoy!
Here's a quick introduction to using a cheap FTDI FT2232H based module (left-hand side on the photo) as a JTAG programmer together with the OpenOCD JTAG software for ARM and MIPS devices. The module I am using for thіs purpose is a DLP Design DLP-USB1232H, which is available from various sources (Digikey, Mouser, Saelig, and probably others) for 20-30 bucks plus shipping, depending on where you live.
By properly connecting the correct pins of the DLP-USB1232H to the target JTAG
device (I used an Olimex STM32-H103 eval board for testing) you can easily abuse the DLP-USB1232H as JTAG programmer. As I chose the proper DLP-USB1232H GPIOs for the TRST and (S)RST pins, OpenOCD even worked out of the box, without having to change a single line of code.
The only thing that's required is to provide OpenOCD with an interface config file that uses the usbjtag "layout". I have already submitted that config file upstream, I guess it should be merged soonish.
The usage is then pretty simple:
$ openocd -f interface/dlp-usb1232h.cfg -f board/olimex_stm32_h103.cfg
And in another xterm:
$ telnet localhost 4444 > init > reset halt > flash write_image erase fancyblink.bin 0x08000000 > reset
This flashes the given fancyblink.bin image onto the STM32-H103 eval board via the DLP-USB1232H JTAG programmer, where fancyblink.bin is an example program from my libopenstm32 project (that aims to create a full-blown firmware library for ST STM32 microcontrollers, similar to what avr-libc does for AVRs). Contributions for libopenstm32 (license is GPLv3 or later) are highly welcome btw., hint hint...
$ git clone git://libopenstm32.git.sourceforge.net/gitroot/libopenstm32/libopenstm32
Full schematics, datasheets, and detailed instructions for the JTAG programmer are available from a small page I created in my Random Projects wiki, which is intended for the various smaller projects I'm working on that don't warrant getting their own domain, wiki, etc:
The Random Projects wiki is open-for-all btw, feel free to use it for any freeish, software or hardware projects of your own if you want.
Anyway, the DLP-USB1232H is a really nice device as it can also be used for many other purposes, such as USB-to-Serial or SPI BIOS chip programming, but more on that in another blog post...
Nice track from Saros, hope you like it.
