It’s been a couple of busy weeks, with the QGIS 4.2 release and meetings and conferences all over the place before a few, hopefully quieter, weeks of summer break.

The Austrian QGIS user group met online on 25 June to exchange experiences with different webmapping solutions, ranging from…
The QuadRF (pictured above) a phased-array radio built around a Raspberry Pi 5 and an FPGA board with picosecond-level timing. It does advanced signal processing and beamforming.
It can see WiFi through walls and track drones in flight.
If the open source community can come up with something like…
My new year's resolution is to play more video games with my wife. Specifically co-operative games. I hate playing competitively; it's rubbish to achieve victory at the expense of someone else. So I asked for recommendations and picked the cheapest things which looked reasonable. Several people…

El uso de estándares permite que los datos dejen de ser…

The 'Special Value' Pi 4 pictured above is probably the rarest Raspberry Pi I own—even rarer than my <lue special edition Pi.
A Raspberry Pi reseller briefly listed a special 'value edition' Pi 4. But the product page 404's now. While it was up, my curiosity got the better of me, and now I have two…
Verily, some of our brethren (and sistren) be afflicted with a sinister disposition. While the righteous scroll using the thumb of their right hand - as is good and proper - an accurs'd minority swing the other way. Look, you try writing an interesting bug report without sounding like a clanker,…
SRFI 277 is now in draft status. Cyclic ports are like infinite string and bytevector input ports:
they produce the elements of a given sequence repeatedly, forever.
While their intended use is as reusable seeds for SRFI 271 random
ports, they are also useful whenever a…
I'm just so bored of talking about AI. It's like listening to vapers tell me how delicious their flavoured poison is. Did you ever meet someone at university who'd just tried drugs for the first time? Listening to a stoner ramble on about their mystic crystal revelations is amusing for the first…
By compiling GNU Emacs directly from the upstream Savannah repositories, you unlock the absolute bleeding edge of the extensible, self-documenting operating system disguised as a text editor.
True autonomy over your computing environment sometimes involves building your own tools and customizing…
SRFI 124 is now in withdrawn status. An ephemeron is an object with two components
called its key and its datum. It differs from an
ordinary pair as follows: if the garbage collector (GC) can prove that
there are no references to the key except from the ephemeron itself and

SRFI 254 is now in final status.This SRFI describes three concepts associated with the storage
management of a Scheme system, ephemerons, guardians, and
transport cell guardians.
An ephemeron is a record structure with a key and a value field.
An ephemeron can be broken. Breaking an…

This is a quick post, mostly for my own reference.
I've avoided LUTs and 'Log' video footage for years1, mostly because of the extra tiny bit of workflow involved. Like RAW photos, 'Log' footage retains the video sensor's full dynamic range, so you can pull more color and luminance information out…
SRFI 276 is now in draft status.
This SRFI is an updated version of SRFI
144 that allows an implementation to support multiple flonum representations.
Each flonum has its own separate library. Each library also has the
ability to inspect properties of the flonum operations, such as rounding

The Software Freedom Conservancy has yesterday
published recommendations for using large language models / generative
AI for free and open source contributions. It's better than I thought it was,
based on initial reactions from my peers, but I am disappointed.
They make 14 recommendations. I have…

Apple FINALLY lets you turn on your Mac remotely, without having to press the power button. In the media, articles suggest it's a reaction to Mac mini power button complaints.
While I agree the M4 mini's power button is in a really dumb spot, that's not why I care about this feature. The two…

Since the PiKVM came out in 2017, there's been an explosion of IP KVMs. I've tested almost every one. But what are they good for?
You can use Remote Desktop, Screen Sharing, or VNC to remote control a computer from anywhere on a LAN. And if you don't have a private VPN, you could use RealVNC,…
