I’ve been mucking a bit with go recently. Nothing special, just doing some small problems that I needed to solve. At work, I have built up a challenge for new candidates. One of them is the old trick of using all the inodes on a file-system. This is a quick one to rule out the ones who have real world experience. So I wrote some code: `I’ve been mucking a bit with go recently. Nothing special, just doing some small problems that I needed to solve. Read more

I upgraded my laptop to Trusty Tahr today. One thing that didn’t work immediately was the Crashplan GUI. It crashes with a SIGSEGV. In summary “C [libsoup-2.4.so.1+0x6c2a1] soup_session_feature_detach+0x11”. I managed to find this bug, and then I found /usr/local/crashplan/bin/run.conf** ** which has a variable GUI_JAVA_OPTS.

I was about to spend $500 to upgrade my existing D630, and then I found out that my $dayjob gives us $1K to buy our own laptop. I threw my hands in the year and decided I would buy a new laptop. Lots of back and forwards on whether I would go back to a Mac or buy the best Intel based laptop I could and run Linux on it. I am already pretty happy with my Dell and their enterprise range are usually well built. I did check out a few other makers, but they didn’t offer the same specifications. Read more
