New version of chess PGN to TeX to PDF converter

OK, I’m shameful. After fighting with Scid’s exporter, and then correcting bugs in pgn2ltx’s source, I finally decided to take a look at that PGN file format. And guess what? It’s already composed of FEN notation. And guess what? that super-über cool new skaknew module for LaTeX gets its input as FEN!!

Updated mate-in-one document, now includes chess coordinates

Update: A new updated version of the PDF is available, which includes which side to play.

After a request to have coordinates on the board, to be able to write answers (a really nice idea, especially that Ido begins writing), I noticed I couldn’t do it so easily, because the LaTeX module (chess12) didn’t support that. What a disappointment!

And the only way I had for converting from PGN to TeX was through Scid (still cool, still being developed), but supporting only exports to TeX with chess12 module. Fortunately, Dirk Baechle wrote a tool to convert directly from PGN format to TeX, using his tool pgn2ltx. That tool, written in C++ hasn’t been updated since 2003, so after a small patch to the source, it worked!

And the best part, is that it generates TeX files for the skak module, the best alternative to the old, dead chess12 module.

Auto-provisioning with Asterisk and ST2030 Technicolor/Thomson phones

An introduction to the ST2030

The ST2030 is one of the few SIP phones distributed by Thomson (now changed name to Technicolor). In fact there are only 2 models: the ST2020, and the ST2030, and also a new one, the TB30, which is the successor to the ST2030. The ST2030 is supposed to have an End-of-Life set to the end of this year (2010), but I read that its EOL has been extended to the end of 2012.
In my personal experience, I think the ST2030 has the best price/functionalities/quality ratio. It has features like:

  • PoE (Power over Ethernet).
  • Headphone plug with a button on the phone to pickup with the headphone (or if you have a compatible headphone, pickup directly with a button on the headphone).
  • XML based Directory support, that you can interface with a remote HTTP server.
  • 4 differents lines/profiles (but not at the same time).
  • BLF (Busy Lamp Fields) to monitor other’s phone status (if they are using their phone, and even possibility to intercept a call).
  • Full compatibilty with Asterisk (tested on Asterisk 1.6+ and 1.8+).
  • Auto-provisioning with support for TFTP but also for HTTP/HTTPS, which simplifies quite a lot the provisioning configuration.

In this document, we’ll see the auto-provisioning process through DHCP+HTTP.
