Sun Apr 05 19:58:29 2009 GMT: Extended Weekend Break in Dublin Mon Mar 09 20:59:14 2009 GMT: DNS Whitelisting for edge.cmeerw.net Sun Mar 08 16:59:41 2009 GMT: Code-generation from Documents Sometimes, knowing how things work really helps - for instance, knowing that Open Document (and Microsoft's Open Office XML) files are actually ZIP archives containing XML files really helps when you want to parse documents to do automated code generation. And if you happen to know some Python you can do pretty amazing stuff in just a couple of lines of code by using the ElementTree XML API to extract data from your documents. Mon Mar 02 18:15:41 2009 GMT: PPP Packet Truncation by BT While IPv6 initially appeared to work fine over my broadband connection, it turns that that I am affected by a bug in BT's network (which is bein used by IDNet) resulting in packet truncation of small IPv6 packets, as described by Andrews & Arnold. :-( Sun Mar 01 19:29:22 2009 GMT: Native IPv6 One nice feature of my new ISP IDNet is that they offer native IPv6 connectivity (in addition to IPv4) - I just had to enable it on my side (by adding "ipv6 ," to my pppd configuration) and it all appears to work fine. So, no more tunneling via SixXS to get IPv6. Sat Feb 21 19:54:10 2009 GMT: Open Watcom 1.8 The Open Watcom project has released version 1.8 of its development suite today which is now available for download. This release includes a number of improvements in the C++ frontend, although it's still a long way to go before it will catch up with the C++ standard (the full list of changes is available from the release notes). Tue Feb 17 07:58:57 2009 GMT: msnbot turning evil As an update to the previous entry, when I created the robots.txt file, I had hoped that msnbot will take action accordingly. But what happened instead is really outragous: the second msnbot requested the robots.txt file, it simply changed its User-Agent header to no longer identify itself as msnbot, but continued requesting exactly the same pages and at the same rate as before. And yes, to be sure, I have checked DNS records and whois information for the offending IP addresses (65.55.51.34 and 65.55.51.37) to check that they really belong to Microsoft/MSN. So, this is how the User-Agent change looks in the Apache access_log: 65.55.51.37 - - [16/Feb/2009:15:28:38 -0800] "GET /index.php?title=Special:Recentchanges&hidebots=0&days=14&limit=100&feed=rss HTTP/1.1" 200 28455 "-" "msnbot/1.1 (+http://search.msn.com/msnbot.htm)" 65.55.51.34 - - [16/Feb/2009:15:28:25 -0800] "GET /index.php?title=Special:Recentchanges&hideanons=1&hideliu=1&hidemyself=1&feed=rss HTTP/1.1" 200 13174 "-" "msnbot/1.1 (+http://search.msn.com/msnbot.htm)" Mon Feb 16 21:27:05 2009 GMT: msnbot considered harmful Sat Feb 14 17:27:08 2009 GMT: Switched broadband connection to IDNet Sun Feb 08 15:47:27 2009 GMT: Xref header filtering for newscache Mon Feb 02 18:05:46 2009 GMT: Finally some snow around here Sat Jan 31 10:23:16 2009 GMT: (Ab)Using OpenVPN | ||||||
