We've barely scratched the surface of the Pi Zero 2's capabilities. [Brian Dorey] shows us how to hack your Pi's WiFi and improve its performance. A u.FL footprint can be discovered in line with the onboard WiFi antenna, implying that someone had to connect an external antenna.
A long-standing objection to making bulk changes to code using automated tools (e.g. to conform to a given code style) is that it clutters the output of git blame. With git 2.23, this does not have to be the case anymore! In this post I will start by explaining the value of git blame and […]
I've spent a little more than a month working with Git now. I can honestly say that while there are many things that I like about Git, there are just as many things that I personally find to be a pain in the butt. Submodules specifically have managed to be a thorn in my side…
This is a little sed challenge that ocurred to me somewhat recently, when I wondered how many weeks were between 2 dates. Of course, I just looked at the calendar and counted, but then I wondered what kind of sed script I’d need in the middle of a cal -y | ... | wc -l pipeline to get the same answer.
A month ago, I built a personal search engine called Monocle that let me search through a trove of personal information I’ve saved over time, from notes to journal entries to bookmarks and tweets. Shortly thereafter, I switched my default search engine in my web browser from Google to Monocle, marking the start of my…

Efficient SQL data transformations & real-time analytics with dbt + Materialize: a powerful operational data warehouse combo.
Firstly this is not just my effort but my team and organisation. Secondly the usual rules apply, this is expert advise and what works for me will very probably cause your whole production stack to blow up and kill people. Lastly this is long so skip to the bit you care about or come along and chat at QCon London 2012
There's been a lot of discussion recently about working fast and being productive in software development, and I thought I'd share some of my own strategies that I've developed for that purpose.

I get asked this a lot, and I write property based testing tools for a living, so you'd think I have a good answer to this, but historically I haven't. This is my attempt to fix that.
Introduction to `lmgrep`: what is it and what it isn't. My a motivation to build it.
A friend of mine recently pointed me at a well hidden command line tool. In the JavaScript framework used by Safari and other parts of Apple’s products, there is a tool called jsc. It’s a command line interface for JavaScript that uses the same code as the rest of the system. You can find the […]

Confusing corners of the unix utilities
Posted to HN. Comments and discussion highly encouraged. Introduction This will be a short example-based guide to (a) awk (b) gnuplot and (c) using them in a script. I needed to graph some data based on the output of a command run a couple times. So what better way to solve that five minute task than to spend an hour…
I love linters. A linter is a program that looks for problems in code without running it. There is something gratifying about running a linter on a codebase and seeing a big list of warnings and errors. Sometimes it can even be fun to fix them!
