Extending Splitwise’s currency conversion

Tom Parker wrote “I’m rather fond of Splitwise, which is an app/website for recording money owed between multiple people. Myself and my partner use it a lot for various expenses, and it’s really useful when you’ve got many different payments, and you need to keep track over time. We’ve got one repeated payment however that’s been in US…”

Argot: a lightweight composable test framework for Go

Matthew Sackman wrote “In a current project we’re writing a number of fairly small REST HTTP servers. There are probably going to be around 10 of these in total so I guess that makes these ‘deci-services’. As part of the testing approach, we wanted to be able to write some end-to-end tests and soak tests, and so went…”

Carpe Diem Word Scrabble

Programming a word at a time

Irene Papakonstantinou wrote “There is an improv game called one-word-at-a-time. It goes like this: two (or more) people collaboratively compose a story, each adding just one word at a time. It sounds easy, but actually humans can be pretty bad at this game! Some of the rules of improv are “be obvious” and “accept offers”. In the context…”

Photography

Photo library wrangling

James Uther wrote “Imagine if you will that I take quite a few photos, but don’t manage them well. Mistakes may have been made. Like, I’ve discovered that when you ask apple photos “don’t import duplicates” it’s not completely foolproof. And if, in a fit of stupidity, you tried to recombine a google photos’ (re-compressed) library with your…”

Hamlet

Generating Beatnik code

Tom Parker wrote “Beatnik is an esoteric programming language that’s been recently amusing me (as they occasionally do). The core idea is that words in the source code are interpreted as their Scrabble scores, and those scores then do things (mostly involving messing with a stack). This leads then to the possibility of an alternate form of the language,…”

A taste of CloudFormation

Ceri Storey wrote “So, we’ve recently had cause to move one of our internal applications to the cloud; which has largely been an excuse for me to get some experience in some relatively modern operations technologies. Amazon’s CloudFormation is designed so that you can declaratively specify the infrastructure resources (eg: virtual machines, load balancers, container configuration, &c) that…”

Given When Then

Ian Rogers wrote “There are, of course, a large number of techniques described as being The Way To Do Software Engineering. I’m sure I’ve not come across them all but the ones I know about and use currently include at least: Impact mapping, Pert charts, Gantt charts, Personas, Wardley mapping, Agile, DSDM, MoSCoW, SMART, INVEST and BDD (I’ve…”

Companionate: sharing logins with QR codes

Tom Parker 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…”

Adventures in TCP latency measurement

Ceri Storey wrote “Re­cently, Google have pub­lished an art­icle on BRR, an al­gorithm that ex­pli­citly meas­ures the round-trip latency and band­width ca­pa­city of the link between two ma­chines (be it in a data­center, or a mo­bile phone) to avoid sending more traffic than is use­ful, causing queues to build up in the net­work that need­lessly in­crease latency. So…”

Cross-grading for fun and profit

Tom Parker 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…”
