once in a while i press enter too early. end result of changing permissions on the whole file system can be quite bad.

few configuration files i use on highly-available active-standby clusters running under debian.

i’ve got seemingly simple php script running every night on one of my servers… on the same machine i started to experience nightly oom-killer. i’ve found out that adodb’s Execute statement can do something completely else than you would expect from it – it loads whole result into memory rather than going row-by-row.

from this site. and it seems to be working. Go to MenuTools -> Error Console Paste the following in the “Code:” text-box: Press Enter or click Evaluate. The database will thence be vacuumed immediately.

it’s been a while since i’ve set up any [non]caching proxy servers. i’ve mostly dealt with reverse proxies, apache2 in 90% of cases, nginx – in few. below few copy&paste configs.

sometimes my backups are not consistent. rsync / samba to blame?

my old linksys router died violently – power led shines, but links on all lan ports were going down after few seconds from bootup. i bought replacement dlink dir-600 and decided to try dd-wrt firmware on it. it went better than expected!.

since a while Sphinx search can be queried not only by their own non-standard interface but also using regular mysql client. they call this feature SphinxQL.

i’ve been happy user of ESVA / global-domination [virtual in my case] appliance for mail and antivirus filtering. unfortunately it seems that was one-man project and it’s pretty much dead by now. official website – http://www.global-domination.org/ no longer works since ~ march 2010.

[scratchpad] read this. debian’s bind9 works just fine. for windows 2003 server dnscmd /Config /EnableEDnsProbes 1 based on this. i got an interesting answer here
