My side project to try and scale myself: Software Mastery School

- 1 min read

So I’ve been working on a little side project for the last couple of weeks to try and create a video based training school to allow myself to scale and maybe not have to repeat myself as much when ever I join a new client.

So I decided to take my post on the Uncommon Sense and turn that into a mini course to try things out.

This was in some ways just an excuse to learn about DSLR filming (read buy some toys), non-linear editing, colour grading etc. Now it’s not perfect (the audio isn’t great as my shotgun mic wasn’t working) but it feels good enough to share.

Uncommon Sense

- 2 mins read

Just because something is compelling doesn’t mean it’s right
i.e. transitive dependencies or the easiest location to add feature X in your codebase

Plugins are a sign of bad composeability or lack of craftsmanship or both
i.e Ridiculous NPM modules that plugin your test tool into your transpiler into your bundler into your web server or equally insane Spring plugins. Maybe look at the unix way…

Libraries are overused and under understood
i.e most day to day problems are easier to solve from first principles than deciphering the README of some library.

This is compatible with the default colour prompt in Ubuntu 16.04, put this in you ~/.bashrc.

Bitmain's new payment system is broken for LTC/L3+ miner. Support just say wait

- 1 min read

UPDATE: Bitmain did eventually respond and fix mine and others orders but it took 8 days without any response in between.

Quite a few people have recently purchased L3+ miners using LTC. (Previous orders using BTC have worked fine). Bitmain are taking the money but not updating the order status.

Their support is not responding to tickets apart from just saying please wait longer (it’s been 4 days for me)
