Release: sqlite-utils 4.1 The first dot-release since 4.0 a few days ago, introducing a number of minor new features. sqlite-utils insert and sqlite-utils upsert now accept a --code option for providing a block of Python code (or a path to a .py file) that defines...

Years ago I wrote about Gilbreath’s conjecture. It’s a simple conjecture; you could explain it to anyone who understands what prime numbers are. See the linked post for a description of the problem. Gilbreath’s conjecture is simple, but it’s also kinda weird. As I wrote before, Paul Erdős speculated that Gilbreath’s conjecture is true but […]

The post Progress on Gilbreath’s conjecture first appeared on John D. Cook.

I used to be one of these people. I read Yudkowsky and was like, OMG recursive self improvement hard takeoff AI is coming. Then I joined the real world and actually tried to do things. At comma, we ship a hardware product of similar complexity to a cell phone, and it’s really hard. Reality has lots of finicky details. I would like to see the authors of this document try to change a bike tire. Even with a superintelligent ChatGPT, I suspect they would struggle.

Opus 4: Henry VI, Part 3

De Tweede Kamer is met reces, en de out of office replies vanuit de overheid beginnen indrukwekkende vormen aan te nemen. Kunnen ze in Amerika nog wat van leren.
Maar, er worden nog steeds dingen gepubliceerd, en het is opvallend hoeveel goeds er recent gezegd is over digitale autonomie.
De tl;dr is dat er een duidelijke wending zichtbaar is. Na een decennium van ontkenning publiceren allerhande stukken overheid nu ronkende teksten over digitale autonomie en staan die teksten ook vol goede voornemens en besluiten.

Adults living with their parents, Samsung’s profits, Native American data centers, Puerto Rico’s electricity grid, and more.

Today's links Workplace "flexibility" isn't: What the gig economy calls flexibility is just risk-shifting. Hey look at this: Delights to delectate. Object permanence: "Alanya to Alanya"; ToS are the internet's biggest lie; Soviet jokes; Fox rapists v gag orders; GBAO is the f...

As a software engineer, how well do you have to understand your own codebase? My guess is that people who work on small codebases with low-turnover teams (say, Redis or games like The Witness) would say “obviously you have to understand it completely, otherwise you can’t do ...

The goal of this post is to answer a simple question: why are the following two definitions of the vector dot product in Euclidean space [1] equivalent for vectors \vec{a} and \vec{b}:

• Component definition: \vec{a}\cdot\vec{b}=\sum_{i=1}^{n}a_i b_i
• Geometric definition: \vec …

The reality is to make augmented reality glasses, you need to put a camera next to your eyes that is continuously recording everything you see and processing that to put information over it. There is not another way around it. And there's certainly not a chip that can fit i...

And why black holes are the ultimate power plants.

North is up (exact, mirrored). 0.53 "/pixel [18.8' x 7.4'] FWHM = 4.2" This galaxy has a massive (and rather bright) tidal tail, but I can't see an obvious companion galaxy. The general consensus is that there's a second galaxy behind it... although a nearby elliptical...

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 recommended Lovers In A Dangerous Spacetime. It's a neat little game which is just short enough to…

Decoding where those integer came from.

The post The case of the mysterious changes to integers when there shouldn’t have been any code generation effect appeared first on The Old New Thing.

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 this, just imagine what governments are capable of.

When you plug a computer into a network, tools like Wireshark can show all the hidden traffic you might not even know is there. WiFi packets are the same, but those travel through the air, allowing snooping without physical access.

Gary Kildall’s death investigation, or the seeming lack thereof, has taken on mythical proportions. Gary Kildall’s story seems to have that effect on people. Just like the story of Kildall allegedly going flying instead of meeting with IBM in August
