Just in case anyone is wondering why we had (or used to have) /bin and /sbin directories as well as /usr/bin /usr/sbin here is my understanding of it. It is because on old Unix systems there frequently wasn&#x2

I implemented an ncdu clone as an rclone subcommand as I love ncdu so much: https://rclone.org/commands/rclone_ncdu/ This means that rclone ncdu runs locally and on your favourite cloud storage. It also runs on Wi

Sudoku is so one of those fiddly and error prone tasks much better performed by computer for me. I wrote a computer solver for Sudoku and that was enough for me, I feel no need to ever play again ;-)

A mirror cube made like this would be perfect as it doesn't need any markings on the faces. https://en.wikipedia.org/wiki/Mirror_blocks (The mirror cube is my favourite shape mod!)

I agree - the best binary search algorithm is the one someone else wrote, preferably in the standard library of the language you are using. I've written binary search algorithms maybe a half a dozen times, and every time I get tripped

Nine years ago I started my hobby project in Go (round about when v1.0 came out). I thought the language looked interesting, kind of like C without the hard parts and with the added benefits of concurrency and I was excited to learn it desp

My reading is that a localhost web server on a port is the way to go. This aligns with what nearly all the other cloud providers do with oauth. > How am I supposed to do that sensibly on a remote server that I'm SSHing into? If you

As a Haskell beginner I have no idea what this error message means. What is `it`? Perhaps it is the argument for ghciInteractivePrint? That is what the error says. But what is ghciInteractivePrint that wasn't in the original code? I&#x

I love my NanoVNA. I used it to tune my 6 band fan dipole. That took a lot of tuning! It works fantastically, and I've made contacts from the UK to Australia with it. I've also used it for measuring the resonance frequency of tune

This is a fun game - more Morse code games are a good idea! The slow setting is painfully slow though - that isn't teaching the right sound of the morse code. So I'd suggest the minimum letter speed should be 20wpm but with spacin

What a fun project. I love SDR. Could you upgrade that to make a 2D picture? Would you need motors to step it around the sky?

I build something out of a 555 just the other day! https://twitter.com/njcw/status/1467522736000053256 Its the primary (20kV) for a tesla coil. The 555 toggles a power MOSFET which drives the primary of a car igni

A good question... The trace looks like it is enclosed in ground up to that moment so isn't intended to radiate until after the SMD resistor, so removing that resistor should be as good as cutting the trace. My hat's off to them t
