ALSA Sound suddendly stops to work on Intel Chipset

Posted by coldtobi | 7 Jul, 2007, 12:17

On my laptop, equiped with an Centrino chipset, my sound suddenly stopped to work. Well suddendly is the wrong word, as I do not use sound regulary on my laptop.

Also, the kmix applet did not show any problem, as it somehow declared my internal (never used) modem as sound card.  Interrestingly, some applications did manage it to properly playback sound (e.g pidgin), but obviously not using alsa as sound backend.

Today I found some time to look after the problem: Alsa loaded the snd_i810m Kernel module, which is the "Modem Module" for the i810 chipset. If this module is unloaded, sound will immediatly start working again. (Okay, after restarting alsa)

But fiddling around with rmmod and insmod every reboot is not my intention, so I needed a permanent fix:

Blacklisting the offender: uncomment the "snd_i810_m" entry in /etc/modutils/alsa-blacklist

This was my first solution to get it working fast. However, this will disable the modem function, but as I do not need this anyway, I do not care.  If you need it, you simply have to insert the module later in the boot process.

ReCaptcha -- STOP SPAM, READ BOOKS!

Posted by coldtobi | 5 Jul, 2007, 23:15

ReCaptcha in ActionSome captchas are well -- weak. Or better said: broken and not an obstacle for the robots. This is, because OCR is doing pretty well, and the obfuscation is sometimes not obsucre.

So why not choose images which have already failed in OCR? 

Exactly this is the approach taken by reCAPTCHA. But where to take words, that failed in OCR? And how to avoid training the bots against this words? reCAPTCHA is refined their approach to also cover this topics:

They take words out of old bookes that are digitalized but not poperly OCRed, because the OCRing failed. They seperate words out of the books, disort them and give that puzzle to the user. They will always present two words: One which has already been decoded and one, which is not decoded yet. Only if both words are entered correctly, the captcha is solved.

Bug in Lifetype

Posted by coldtobi | 4 Jul, 2007, 19:39

I do not know yet, if it is because of my configuration, and I currently unable to file a bug report, but I' gonna to investigate this a little more.

If the settingsin Administation -> Global Settings -> URL are set to "Mod Rewrite", the "next-Links" and page-number links at the bottom of the main pages stop working. If clicking on them, you alway get on the first page.

On any other settings, this is working loke a charm, so I am using "Custom URLs" now, with default settings.
