Mon Feb 02 18:05:46 2009 GMT: Finally some snow around here Sat Jan 31 10:23:16 2009 GMT: (Ab)Using OpenVPN Sat Jan 31 10:05:03 2009 GMT: Twinkle 1.4 Bug Last weekend a new version of my favourite soft-phone was released, but unfortunately, it contained a serious bug when compiled with an old version of the (or no) speex library which results in no outgoing audio. I have been able to track down and fix the bug. BTW, a package for Ubuntu hardy heron with that fix is available from my .deb packages page. Sun Jan 04 16:17:39 2009 GMT: Python DB-API Rant SQLite really is a great database engine, but as it only supports database-wide locks, it's not really suitable if you want to concurrently access the database from different threads/processes. So I though, just switch to PostgreSQL which should be easy in theory as I am already using Python's DB-API 2.0. Unfortunately, it's not that easy in practise, as the DB-API specification is not strict enough to make it really useful (and implementations have their own bugs on top of that). The main issue is that Python's built-in sqlite3 module uses "?" as the placeholder in prepared statements, whereas all PostgreSQL DB-API implementations use Python format strings (e.g. "%s") as placeholders. To make matters worse, some implementations expect "%d" for integer parameters, while others expect "%s". So, essentially you can't use plain DB-API to write portable applications, but need another abstraction layer on top of it... Sat Dec 27 21:24:53 2008 GMT: vAdmin SNMP Service My new vServer provider apparently uses vAdmin as the management interface for the vServer. But one of the less than ideal side-effects of this is that the initial installation came with a snmp daemon (as part of the vAdmin setup) that was configured with an easily guessable (read/write) community name (and no IP-based filtering). Needless to say, one of the first things I did was to deactivate that snmp daemon - but if you are also using a vAdmin based vServer, you might want to check if there is a snmp daemon running you don't know about... Mon Dec 22 10:26:51 2008 GMT: 64-bit vServer While migrating to the new virtual server, I decided to go with the 64-bit version of Ubuntu hardy heron which means that most packages on my .deb packages page are now available in 32-bit and 64-bit. Sun Dec 21 10:21:31 2008 GMT: Server Migration In the past few days I migrated edge.cmeerw.net to a new host - this time it's hosted by INGATE in Munich. By switching to a new hoster I get three times the amount of RAM (768 MB instead of 256 MB) for the same price as before (and I was told to get native IPv6 connectivity next year).
