First days in Google

2007-10-18T17:29:00.000+02:00

I disappear some time, because the first days as a Googler was crazy. I started as the first SysAdmin at Google Belo Horizonte and first at South America, so you can imagine the overload of information that I had to learn and make it easy for my next colleages. But now I have reinforcement (Stratus).

I'm loving to work at Google. It is really the best place to work and I can still play with Ubuntu all the time.

I expect to contribute with a bunch of patches to Ubuntu and Debian during my projects here.

Feisty Fawn and Texas Instrument Card Reader

2007-03-16T06:22:00.000+01:00

If you have an Multimedia Card Reader 5 in 1 from Texas Instruments, if you don't know, use this command to confirm:

$ lspci | grep "Multimedia Card Reader"
05:06.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD)

You will not be able to use this card reader with new Ubuntu 7.04 (Feisty Fawn), because there are some problems with tifm (Texas Instruments modules) and MMC core on kernel 2.6.20. The discussion on linux kernel mailing list is here.

Alex Dubov, the maintainer of tifm, said that:

Unfortunately, driver shipped with 2.6.20 is buggy. Please use the standalone version of the driver, for a time being.

So if someone has this device, the solution is:

Download the device module: http://prdownload.berlios.de/tifmxx/tifm-0.8d.tar.bz2
Compile (you need the package build-essential ):

$ mkdir tifm; cd tifm
$ tar xvfj tifm-0.8d.tar.bz2
$ make
$ sudo make install

Now you have tifm working standalone. You have to reboot or reload modules for correct use. Remember that every time you have to upgrade your kernel, you need to re-run "make install".

Pavel warned me that this problem is history in kernel 2.6.20-11.18:

Big "Thank you" for our core developers. :-)
