Vellere: exposing Github vulnerability notifications to Slack

Tom Parker-Shemilt wrote “A few years ago, Github introduced vulnerability alerts on repositories and although it was initially just for Javascript and Ruby, they’ve since expanded it to Python, Java and .Net and I’m guessing more languages are also on their roadmap. It’s a useful feature, except for one problem: it’s notifications are poorly implemented. They appear to…”

On the value of maintenance

Tom Parker-Shemilt wrote “Most of our posts here talk about new software, but there’s also a lot of value in the longer-term maintenance of code and given I’ve done some of that recently, I thought it worth revisiting various earlier projects in that light. None of these are really large enough to have their own post, but collectively…”

Serialising Rust tests

Tom Parker-Shemilt wrote “I’m once again prodding the potboiler tests and a couple of the tests I was doing wanted to mess around with the shared database. This had the problem that multiple tests would collide with each other, as the default for Rust testing is to run everything in parallel. This is unusual, but good in many…”

Making a Spaceteam timer app with Flutter

Tom Parker-Shemilt wrote “Some of you may have run into the excellent Spaceteam mobile game. It’s best described as ‘co-operatively shouting at each other to fix your broken ship’, and it’s a lot of fun. Some fun folks then went and made a card game variant of it, which is similar in many ways. Now, both games have…”

Clincher: checking your signed git commits

Tom Parker-Shemilt wrote “Recently for a project with tight regulatory requirements we decided that git signing throughout the project was a good idea. There’s a debate about it’s level of effectiveness, given that all it tells you is that a particular commit was made from a particular developers machine, and if they’re not careful, they can end up…”

Not all watchers are created equal (or how to make yak shaving useful)

Tom Parker-Shemilt wrote “I’ve been hacking around with a Clojurescript project recently, and it resulted in a certain amount of yak shaving when I found the watcher system I was using was eating a lot of CPU. On the one hand, yak shaving is bad, because you’re doing other things that aren’t the core task you’d originally meant…”

How to be a Rockstar developer!

Tom Parker-Shemilt wrote “You’ve probably followed that clickbait of a title and are hoping for some super-secret tips on how to be a ‘Rockstar developer’, and I’m not going to disappoint on that (technically). But before that, I’m going to note to those of you lucky enough to have not seen that particular variety of recruiter spam that…”

Wharf: Dokku Web frontend

Tom Parker-Shemilt wrote “As long-time readers of my posts may have noticed, most of the apps I talk about building here are deployed to Heroku. This is mainly because I’ve been a long-term user of theirs, and so when they changed their pricing model a couple of years ago, I got grandfathered in a ridiculous number of free hours.…”

Sked: merged calendars as a service

Tom Parker-Shemilt wrote “I have a little bit of an obsession with calendars, mostly generated ones via a variety of tools. I don’t do well with pen-and-paper for this sort of things, and one of these days I will write the Grand Unified Todo Manager To Rule Them All (which will also eat emails, Calendars and probably a…”

Panegyric: showing off what we’ve done on Github

Tom Parker-Shemilt wrote “Last month, I said we’d be talking more about open source work that we’re doing. This month, I’ve been building Panegyric, a WordPress plugin (which is what this site is written in). This plugin (which isn’t live on the site yet, but will be soon) lists all the Github pull requests we’ve recently done. However…”

You should be contributing to open source. Yes, all of you!

Tom Parker-Shemilt wrote “In the wake of Hacktoberfest 2017 finishing (and I’ve managed to get the t-shirt again for the 3rd year in a row), I figured I’d try and convince a few more people to give back to open source projects. This is something I do just as part of my day-to-day work, and I want to…”

Android Bletchley Password Store

Nick Karandejs wrote “My last project was building an Android password store based on Bletchley and I’m going to describe the process I went through along with some of the issues I had in the process. I started by making Bletchley run on Android… which required a bit of work. First, nothing worked since converter lookup failed for…”
