BoardGameGeek graph

Tom Parker-Shemilt wrote “I’m a bit of a gamer, although I’m using that term to cover many things including pen-and-paper RPGs, board games, various forms of LARP, and occasionally a bit of video gaming. Of course, with all those options there’s the problem of what should you play. One of the solutions that people have come up with is…”

Companionate: sharing logins with QR codes

Tom Parker-Shemilt wrote “I’ve run into a problem a few times recently, which is that having done all the right things with passwords i.e. using a password manager and having them be unique strings of basically random garbage, I now need to enter them in somewhere I haven’t got my password manager running on. I’m typically sitting in…”

Cross-grading for fun and profit

Tom Parker-Shemilt wrote “First thing you’re probably wondering: What’s cross-grading? Well, it’s a bit like upgrading, except more sidewise than definitely upwards. It involves the changing of the architecture of a system, most typically from 32-bit to 64-bit, and most typically from x86 to x86-64 (although similar options are apparently doable for other architecture families, including ARM, MIPS and…”

Pigtail: task queues with Potboiler

Tom Parker-Shemilt wrote “Last month, I wrote about Potboiler, my AP Event Sourcing system. At the time I’d built a K/V store on top of Potboiler, mostly just as a test application. Potboiler isn’t really intended to be talked to directly by most clients, but will have some other form of service or store that sits on top…”


Tom Parker-Shemilt wrote “Over the last couple of years I’ve been reading and talking about a lot of things related to distributed systems. This is a common train of thought around here, and after working on this on and off for the past 18 months or so (the version you’re seeing here is in fact version 3 having repeatedly changed…”

Using the BBC micro:bit with PlatformIO

Tom Parker-Shemilt wrote “I recently acquired a micro:bit, the new BBC device intended for helping computer education. After a bit of delay, they’ve finally starting shipping the device, and now members of the public like myself can grab one. So, why this device in the middle of a sea of other options in the modern embedded environment? Well,…”

Dawn: Mobile bus stops display

Tom Parker-Shemilt wrote “When I’m out and about, I find myself repeatedly wanting to know when a bus will stop near where I am. This generally involves a phone as the TfL Countdown displays are a bit thin on the ground. Despite the advent of such things as Citymapper, I’ve still been a fan of the Countdown mobile website,…”

Docket: Fun with Todoist and Beeminder APIs

Tom Parker-Shemilt wrote “So, I recently changed over my todo list usage to use Todoist. However, now I had a chunky amount of my phone screen chewed up with both a display of that and my existing Beeminder list, and I wondered if I could somehow merge the two. Also, because my Beeminder emergency days are one of the significant sources…”

Scrutiny: Github permissions audit and backup tool

Tom Parker-Shemilt wrote “These days we’ve all got an awful lot of our code in Github, and so we really need both a backup (so we can cope with them having a catastrophic failure) and a permissions auditing mechanism (so we know who’s getting access). For the latter, some of you may be saying “just use the audit…”

Herder: Automagic scheduling of a convention

Tom Parker-Shemilt wrote “About once a year I go off with about 30 of my friends and go and play role playing games and board games for a week in a big house out in the country. This is kinda awesome, but as we’ve increased the numbers we’ve been having fun with the scheduling. Namely, we need to…”

Talky Jukebox bot

Tom Parker-Shemilt wrote “Previously I talked about our soon-to-be-new Jukebox (which is currently blocked on going live due to a Mopidy bug). At the bottom of that post, I mentioned Slack support, but hadn’t figured out what sort of form this support would take. The Mopidy search interface is perfectly good, but having something that notifies our #jukebox Slack channel…”

Yet Another Jukebox

Tom Parker-Shemilt wrote “LShift has for a significant part of it’s history (at least 9 years, according to the blog post in 2006 about an earlier version) had an in-office jukebox. When I arrived here to begin with in 2010, there was the aforementioned earlier version, written in Erlang, and I have anecdotal reports of predecessors to that.…”

Raspberry Chef

Tom Parker-Shemilt wrote “Last month I wrote about temperature monitoring, and how I ended up using Raspberry Pi’s. I’m still fiddling around with their configuration, and I ran into a few problems. For starters, if I brought them home, they knew how to talk to the work WiFi, but not my home system, and vice versa (although this is…”

Pyrexia: IoT office temperature monitoring

Tom Parker-Shemilt wrote “Most of the projects I write about here are pretty much complete, or at least good enough. This one is a little bit more of a work in progress for reasons that will become clear fairly soon… One of the ongoing conversations in LShift over the years has been regarding the temperature in the office. It…”

Kitten videos: an engineering approach

Tom Parker-Shemilt wrote “A little while ago one of my colleagues put up a kitten video feed on one of the spare monitors in the office. This was liked, but as we rapidly found out there was a few problems. Biggest of which is that kittens have a fairly well known failure state: they fall asleep. Sleeping kittens are…”

Waveform Necklace as a Service

Tom Parker-Shemilt wrote “I’m generally quite fond of laser cutters and cute crafting things done with them, so when I saw a Waveform Necklace Instructable the other day, I had to give it a go. Basic idea is that you take a sound recording’s waveform and reduce it’s waveform down to a level where it can be reasonably represented…”
