DNSSEC and SSL certificates
Leave a Comment
Dr. Jörg Schweiger of the German domain name registry DENIC posed an interesting question at this morning’s first DENOG meeting, in Frankfurt.
Would domain name users who are concerned about the accuracy of data served pay extra for the ability to sign their DNS zone ? A handful of people in the room raised their hand [...]
innodb_data_file_path bug with long line limits
1 Comment
I have a MySQL server which was starting to scrunch its data more and more slowly. Some analysis led me to blame an autoextending innodb file which had grown somewhat unkept to several GB. I wish the autoextend behaviour could be configured to grow more files rather than grow one file, but that’s another rant. [...]
Extreme Switch / OpenSSH bug

I have been trying to get a patch applied to Debian’s openssh-client packages since February which would fix a bug that prevents me from logging into Extreme switches via ssh:

IPv4 Run-out policies in Europe

They all show that the effects of scarsity of IP addresses will be felt before the final few addresses become assigned to end [...]
18 months? And google are nimble?
Leave a Comment
Google recently announced that they’d done a front-to-back implementation of IPv6, using engineers’ spare time, in 18 months. Cue well over 100 comments on slashdot claiming that this goes to show how hard implementing any sort of v6 service is at all, given it takes a company known for hiring smart people as long as [...]
Escaping a pipe inside xargs
2 Comments
I’ve got a nasty dose of bashfail this morning. I had a bash one-liner which generated a list of strings. I needed to iterate over that list in xargs, but the command in xargs was itself a dirty multi-command one-liner :
crazy | stuff | xargs -i {} this {} | that {} (with this and [...]
iPhone battery life
3 Comments
The iPhone is the best portable computer I have ever owned, in every regard but one – the battery life for me was shockingly bad. When it reached the point where I could not go a full day without charge, I decided that I would have to return the device, because it was not useful [...]
