RachelF··on Hidden interface controls that affect usability
Similarly the disappearing menu items in common software.

Take a simple example: Open a read-only file in MS Word. There is no option to save? Where's it gone? Why can I edit but not save the file?

A much better user experience would be to enable and not hide the Save option. When the user tries to save, tell them "I cannot save this file because of blah" and then tell them what they can do to fix it.

RachelF··on Sirius: A GPU-native SQL engine
It requires "CUDA >= 11.2"
RachelF··on Sirius: A GPU-native SQL engine
Pity it requires Volta 7 which is rather high end for fiddling around on at home.
RachelF··on Snow - Classic Macintosh emulator
It's a bit crazy that Apple still prosecutes people who put these old ROMs online.
RachelF··on What If We Had Bigger Brains? Imagining Minds Beyond Ours
European Neanderthals probably had 15% more neurons than modern Homo Sapiens, based on brain volume.

We're still here, so bigger brains alone might not be the reason.

RachelF··on The accuracy of weather forecasts
Farmers have a reason to be sceptical:

The BoM caused hundreds of millions of $ of damage to livestock farming - they warned about a huge drought in 2022 causing massive livestock culling. Instead there were years of above-average rainfall.

RachelF··on Ground control to Major Trial
Sounds a lot like it is BlackSky NYSE: BKSY

RachelF··on docker2exe: Convert a Docker image to an executable
you need "Docker for Windows", which runs a Linux VM which then runs Docker.
RachelF··on Design and evaluation of a parrot-to-parrot video-calling system (2023)
> How so or why so, considering their brain size relative to their body, is not well understood.

One factor is neuron size. Bird neurons are around 0.4 the length of mammalian neurons, so you can pack in around 8 times the neurons in a given volume.

A large parrot has the same number of neurons as a medium sized dog.

RachelF··on The Beauty of Having a Pi-Hole (2024)
I've seen Windows 11 ignoring DNS settings too, for Microsoft telemetry, ads and updates.
RachelF··on Jepsen: Amazon RDS for PostgreSQL 17.4
I wondered how Microsoft SQL Server fares, but not it's tested in the long list of databases:

RachelF··on Reworking 30 lines of Linux code could cut power use by up to 30 percent
I appears that this academic is very good at public relations.

They mix interrupts and polling depending on the load. The interrupt service routine and user-kernel context-switch overhead is tiny computationally and hence in power usage.

Also, most network hardware in the last twenty years has had buffer coalescing, reducing interrupt rates.

RachelF··on Intelligence Evolved at Least Twice in Vertebrate Animals
Speaking of Cheetahs, pigeon fanciers like to compare their birds to Cheetahs.

A 200gram grain-fueled homing pigeon can maintain 60km/h for an hour. A cheetah can do that for maybe a minute.

I've always thought this is not really a fair comparison, as flying through the air probably requires way less energy than sprinting.

RachelF··on Intelligence Evolved at Least Twice in Vertebrate Animals
Bird neurons are typically around 40% of the length, or 1/9 the volume of mammalian neurons. This means they have around 9x the number of neurons per unit volume.

A large parrot has around the same number of neurons as a beagle dog.

Combined with weight savings, this may allow their brains to work faster, which is useful for a flight computer.

Birds have other features which are superior to mammals. For example, their flow-through lungs allow for more efficient gas exchange.

However, having to fly means weight reduction has been a big driver of evolutionary compromises. A bird that can fly cannot carry large fat reserves around. They are not resilient when sick and often die quickly after the onset of visible symptoms.

RachelF··on The software engineers willing to pay $10k to help them land a coding job
I've had a similar experience. Most of the people I've worked with are 4-6 out of 10. But I suppose that's a normal distribution.

I've encountered a few 1's and 2's but they generally don't last too long. I've also encountered a few brilliant ones, but their code was understandable only to themselves, and often didn't meet a spec.

RachelF··on US Administration announces 34% tariffs on China, 20% on EU
Foreign countries like Japan and China own around $1.8T in US bonds. These are valued in dollars, like stocks.
RachelF··on Mozilla launching “Thundermail” email service to take on Gmail, Microsoft 365
Use Betterbird. They upgrade Thunderbird and fix bugs.
RachelF··on DEDA – Tracking Dots Extraction, Decoding and Anonymisation Toolkit
The original somebody was likely the US Secret service, who are also responsible for US dollar currency forgery policing.

When color printers/copiers first appeared there was a concern about people photocopying money. The old joke was that your color photocopier "would pay for itself in no time".

RachelF··on DEDA – Tracking Dots Extraction, Decoding and Anonymisation Toolkit
I'm surprised there's not been a class action against printer manufacturers for all the extra yellow toner that's been used.
RachelF··on How each pillar of the First Amendment is under attack
One thing not on the list (yet) is the freezing of protesters' bank accounts that happened in Canada.

Or the de-banking that happens to politicians in the UK.

Or the jailing of whistleblower lawyers that happens in Australia.

RachelF··on Bitter Lesson is about AI agents
I think an even more bitter lesson is coming very soon: AI will run out of human-generated content to train on.

Already AI companies are probably training AI with AI generated slop.

Sure there will be tweaks etc, but can we make it more intelligent than its teachers?

RachelF··on The Origin of the Pork Taboo
Yes, pig organs can be used for human transplants, the tissue types are similar.

Perhaps the pork prohibition also has some anti-cannibal echos in it. You're never sure if your pork stew is grandma?

RachelF··on Our interfaces have lost their senses
The "great flattening" fashion has made computers harder to use for many people.

Older UIs separated computer output from where user input is expected. Compare Windows 7 or 2000 to Windows 10 or 11 and the older Windows versions win. It's the same with Android.

UX designers follow fashion as much as the garment manufacturers on the catwalks of Milan, even if the fashion is uncomfortable.

Just because something is new, that doesn't mean it is better.

RachelF··on YouTube DRM added on ALL videos with TV (TVHTML5) clients
AI is probably the threat executives understand.

There are also some pretty good third party YT clients like GrayJay https://grayjay.app/

These let you follow creators across various video platforms in one app. Bad for YT lock-in that Google wants.

RachelF··on A Post Mortem on the Gino Case
>"At worst, straight to jail."

The "at worst" is worse: Two recent Boeing whistleblowers died in rather suspicious circumstances.

RachelF··on Sublogic Flight Simulator
Sopwith[1] as a test of PC compatibility for clones.

I later years it was a great test of how much faster computers had become as it assumed it was running at 4.77MHz

RachelF··on Sublogic Flight Simulator
Wow - that's a trip down memory lane - I learned the basics of flying from Flight Sim 1 on an Apple. The manual was pretty damn good. The application was amazing for its time.
RachelF··on A Post Mortem on the Gino Case
It's ironic that one of Gino's partners in crime, Dan Ariely, has been writing bestselling pop-sci books about dishonesty, based on his own faked data.
RachelF··on Zentool – AMD Zen Microcode Manipulation Utility
I would guess it is a BIOS patch, just like the microcode normally is.

So it probably needs to be installed at every system boot.

Perhaps someone more knowledgeable can correct my guesses?
