It’s been a day for nice little technical surprises. On the tube ride to work this morning I started flicking through Cisco Routers for the desperate (2nd edition) and found a quote on the first page from the 1st edition book review I did a couple of years ago. I also had my first fully git workflow patch accepted by upstream. It was only a couple of lines of code but it means I’m gradually getting comfortable with the git toolchain.

I like Ubiquity. It puts a lot of the sites I used on a regular basis close to hand without making me dig through my bookmarks (or del.icio.us account). In a small burst of productivity, and to avoid real work, I decided to put a command together for the Puppet Type docs at Reductive Labs. If you have the Ubiquity plugin installed you should be able to install a copy of the command from the Ubiquity Puppet Types Command page (which I no longer provide as of 20141224). Read on →

I wasn’t able to get to the actual talks but luckily the Moose talk slides are now all online (apart from Moose for Ruby programmers which has instead been expanded in to a blog post). By all reports it was another excellent night and I’ll have to keep the evening free for the next one. Now I’ve read the slides and heard so much positive feedback I think it’s time I tried Moose for a couple of projects. Read on →

If you already know GDB then this book might be useful. It’s full of command summaries and option listings but lacks an actual introduction or any walk through examples. A google for GDB tutorials bought back some well written intros with actual sample code I could work through which is probably a more useful approach for most people.

We recently had an odd one where the Nagios check_http check, which was both checking for the presence of a string in the response and that the page loaded in a certain time frame, went from reporting a ‘CRITICAL - string not found’ to a ‘HTTP WARNING: HTTP/1.1 200 OK’. My first thought, as this was a site pending migration, was that the URL had moved to a slower machine with the fixes released to it. Read on →

I like vim, I think it’s a great editor worth investing time and effort in to learning but I also think it’s one of the most horrible things to watch an inexperienced user typo his way through while you’re urgently waiting for them to finish the damn edit. My favourite one this week (and it’s only Tuesday) is looking for probably unique phrases that you can later search for to return to a specific part of a document. Read on →

Logs are a wonderful thing. If done correctly they point out the source of all errors, show you what’s running slow and contain useful information on how your system is running. At every place I’ve ever worked they’ve been busy, full of odd one offs and too often overlooked. I’m going to be doing a fair bit of log processing next week so expect lots of little toolchain scripts like syslog-splitter.pl to be checked in to git and mentioned here. Read on →

I recently ‘attended’ my first MySQL University presentation - Scalability Challenges in an InnoDB-based Replication Environment. The service itself is great, you sign up, log in and then watch the speaker present in one window while listening to him speak and reading the slides (in the main part of the screen). Everything you’d expect really. The subject wasn’t anymore exciting than you’d guess (but what do you expect with that title?) but the speaker knew his stuff and a couple of the Solaris commands shown will be useful to me in the future.

I’m going to try and get to more LOSUG meetings this year and the January presentation by MC Brown has done nothing to put me off. Although some of the audience tried their best… First up - the good. The actual presentation, MySQL/DTrace and Memcached, was very well done. The speaker was funny, well rehearsed and knew his material extremely well. The MySQL DTrace probes are made to be used in demos and are very enticing. Read on →

It took me a while to warm to Bill Bailey as a comedian. His slower, more laid back humour is a change in pace from what I normally like but Tinselworm, like all his live shows, is an excellent mix of music and mirth. If you like Bill Bailey then it’s another must have, if you’ve never watched him then go for a little trawl through youtube (start with this) and if you don’t like him then you’re just weird.
