TL;DR I thought I could put Squid in front of an SSH tunnel, but it can’t do that. Thankfully Polipo can do the trick. Why? I was quite happy when it was just spies that were allowed to spy on me (even if they might have been breaking the law by doing so), but I […]


TL;DR A relay board from eBay combined with a cheap wireless doorbell from Amazon allowed me to extend my existing wired doorbell. Background I got the loft of my house converted into a home office. I love it up there, but if I shut the door (to keep noise out) then I can’t hear the […]


TL;DR Copying the contents of one SSD to a larger one (and making use of the extra space) should be simple, but there are a few gotchas. A combination of AOMEI Partition Assistant Standard and some command line tools got the job done though. Background SSDs have been reasonably cheap for some time, but now […]


Back in March I wrote about Using Overlay file system with Docker on Ubuntu – those instructions applied to Ubuntu before the switch to systemd e.g. 14.04 and earlier. The move to systemd means that changes to /etc/default/docker don’t have any effect any more. To get systemd to dance along to our tune needs a file like […]


TV Cable Tidy

08Nov15

TL;DR If you’re putting a TV on a modern open stand then the ancillaries and cables can make a real mess and spoil the overall look. I put a board onto the VESA mount on the back of my TV to hold everything, which then let me arrange the cables into one tidy trunk running […]


Late last year AWS launched Private DNS within Amazon VPC as part of their Route 53 service. This allows customers to create DNS entries that are only visible within a VPC (or group of VPCs). It’s also possible to have ‘split horizon’ DNS where servers inside a VPC get different answers to the same queries versus users […]


I’m a big fan of Github Gist, as it’s an excellent way to store fragments of code and config. Whatever I feel I can make public I do, and all of that stuff is easily searchable. A bunch of my gists are private, sometimes because they contain proprietary information, sometime because they’re for something so […]


Apache 2.4 changes things a lot – particularly around authentication and authorisation. I’m not the first to run into this issue, but I didn’t find a single straight answer online. So here goes (as root): If you want mpm-worker then do this instead:


Dockercon #2 is underway, version 1.7.0 of Docker was released at the end of last week, and lots of other new toys are being launched. Time for some upgrades. I got used to Docker always restarting containers when the daemon restarted, which included upgrades, but that behaviour went away around version 1.3.0 with the introduction […]


Last week Jérôme Petazzoni did an excellent (abbreviated) version of his ‘Deep dive into Docker storage drivers‘ at the London Docker Meetup. If I wasn’t convinced enough by that, Jessie Frazelle hammered home the same point in her QCon Presentation – AUFS is where it used to be at, and the new king is Overlay. I set about […]
