Comparing Docker images

jon.dowland.name log - Wed, 03/02/2016 - 2:29pm

I haven't written much yet about what I've been up to at work. Right now, I'm making changes to the sources of a set of Docker images. The changes I'm making should not result in any changes to the actual images: it's just a re-organisation of the way in which they are built.

I've been using the btrfs storage driver for Docker which makes comparing image filesystems very easy from the host machine, as all the image filesystems are subvolumes. I use a bash script like the following to make sure I haven't broken anything:

Network Attached Storage

little and large

little and large

I've just upgraded my home Network Storage box. Until now, it was very discreet, about the size of a car radio. It lived on one of my bookcases and I was very happy with it but it could only take 2.5" sized hard drives and I've outgrown what you can fit on them.

Game boxes

My brother and I found these whilst tidying up the stuff that we've left at our parent's house. What on earth should we do with them?

Download codes are distinct copies of albums

jon.dowland.name log - Mon, 07/12/2015 - 8:02pm

In CDs should come with download codes, I argued that CDs should come with a coupon to obtain a digital copy of the album, much like a lot of modern vinyl releases do.

On BBC 6 Music

Back in July I had a question of mine read out on the Radcliffe and Maconie programme on BBC 6 Music. The pair were interviewing Stephen Morris of New Order and I took the opportunity to ask a question about backing vocals on the 1989 song "Run2". Here's the question and answer (318K MP3).

It's been at least a year since I last did any work on Debian, but this week I finally uploaded a new version of squishyball, an audio sample comparison tool, incorporating a patch from Thibaut Girka which fixes the X/X/Y test method. Shamefully Thibaut's patch is nearly a year old too. Better late than never...

Useful Mac programs

jon.dowland.name log - Wed, 11/11/2015 - 2:57pm

A little over a year ago I wrote about how I'd been using a Mac as my main work machine. I hadn't written anything on the subject since. Here are four useful Mac programs that I can recommend to people.

Ikiwiki-in-a-box Docker container

jon.dowland.name log - Fri, 16/10/2015 - 3:12pm

For a while I've been wanting to tidy up some of my existing ikiwiki hacks, as well as test some changes I'd like to make to this site, but I hadn't had much success with setting up environments to play with it. That was until earlier in the year, when as a bit of an experiment I tried to put ikiwiki in docker.

Johnny Marr

jon.dowland.name log - Mon, 12/10/2015 - 4:04pm

Last night I saw Johnny Marr play at Newcastle University Student's Union. This is the first time I've been to a gig at the refurbished NUSU. I think the last gig I saw there was Nouvelle Vague in around 2007.

WadC 2.0 released

WadC

This week I released version 2.0 of Wad Compiler, a lazy functional programming language and IDE for the construction of Doom maps.

Version 2.0 is the first version in about four years and adds a fair number of features, most notably the ability to compose textures in your code and a basic command-line interface.

Koločep, Dubrovnik, Dalmatia

Trsteno

Trsteno (near Botanical gardens)

This year, Sarah and I spent two weeks off the coast of Dubrovnik, on Koločep island. We'd never been to Croatia before, and I was a little nervous that if there wasn't much to do on the island, we wouldn't be able to get elsewhere particularly easily. I needn't have worried: We thoroughly enjoyed our stay. It might even be my favourite holiday so far.

New camera

jon.dowland.name log - Tue, 21/07/2015 - 3:25pm

Sony RX100-III

Earlier in the year I treated myself to a new camera. It's been many years since I bought one, which was a perfectly serviceable Panasonic FS-15 compact, to replace my lost-or-stolen Panasonic TZ3, which I loved. The FS-15 didn't have a "wow" factor and with the advent of smartphones and fantastic smartphone cameras, it rarely left a drawer at home.
