Software

My production box crashed with:

** glibc detected ** nginx: worker process: malloc(): memory corruption: 0x00000000012f9d20 ***
** glibc detected ** nginx: worker process: malloc(): memory corruption: 0x00000000012f9d20 ***
2013/02/21 21:34:30 [alert] 20048#0: worker process 7258 exited on signal 9

Which was bad.

I like ETags to reduce page loads, and Nginx does not support them. To get it support ETags, there is a module in GitHub, which I am using.

After a nice couple of hours of debugging it turned out that all other places in Nginx-code call ngx_memzero() before calling ngx_open_cached_file(). It turned out to be the crucial mistake in the module. I filed an issue to the original author to notify everybody else.

My production boxes did actually return weird errors now and then, which I didn't think much of. Weird things happen sometimes. However, this fix seems to help, there are no worker processes dying and page load erros seem to gone away. Hopefully the box does not crash again.

Adblock Plus is a great add-on for Fire-/Waterfox, Chrome and Opera. It really keeps the unwanted commercial crap out of your browsing experience. There are so many badly designed and implemented ads in the world, that they triple or quadruple page loading time, look ugly and sometimes when programmer has really been a total idiot, a failure to load the stupid ad crashes the JavaScript functionality which would be otherwise needed. Programmers: Test your site with ads blocked, please.

My point is, that if ad programmers are idiots, equally idiotic programmer in Adblock Plus project decided that I cannot type. Sure, now and then my fingers do not hit they keys they should have been, but I most definitely don't need a machine to fix my typos. That's for sure. Now the braniac that made the decision that I cannot type, enables this useless helper as default.

The entire feature is fucking useless! It never works when I mis-type, but it always triggers when I enter the address correctly. Looks like somebody else has the same issue and wrote instructions on how to disable the I-think-you-wrote-it-wrong-I'll-make-it-much-worse-for-you -addon.

Can you show me a single working example, where machine would 100% detect user's mistake and 100% of the time correct it properly? No you cannot. Nobody can.

What happened to Symantec / Norton?

They used to be the backup company, but they have not release anything after Norton Ghost 15.0 (yes, I am an user). That is from Nov 2009, making newest version over 3 years old! On top of that they announced that Windows 8 will not be supported. WTF!? That is an excellent indication of their commitment to the product. Those who cannot understand sarcasm: they abandoned the product years ago.

Screw you Symantec! I'm going home.... erhm... to Acronis True Image. They release updates, they release new versions, they support Windows 8. Their level of commitment is from a totally different planet than Symantec.
