Retired computer/electronics design engineer. In computers since before there were microprocessors. Kicking myself I chose to not sell my S-100 to buy an Apple I board, and just wait a while for an Apple II. Now an Apple I is worth around $200,000. Dammit.

Agreed. A link to a plaintext listing of titles and authors, would be very useful to those (like me) who enjoy owning physical books.

Splendid. Someone found a way to break Browser Scrolling. (Firefox 115.16 for Win7)

Well done.

I'd suggest that only people who are already overweight will be trying intermittent fasting. Needs a study with randomly selected people who are put into two groups - overweight and lean, then half of each group start intermittent fasting.

Also, since when is just restricting eating to certain hours of the day 'fasting'?

My experience: I was overweight, 95 Kg. Two years of not getting anywhere with attempting to reduce intake, due to living alone, which makes cooking small meals difficult. Heard of "36 hour fasting", and decided to try it. Except I felt '36 hours' is half-arsed. So to simplify I just do 48 hour fasts. Turns out it's very easy, and I can reliably drop a couple more kilos anytime I choose to do another fast or two. Currently down to 84 Kg. Will be 83 after the current one probably. Once I'm at 80kg, I'll decide whether to continue down to 75 or so.

I hadn't seen this before, thought it looks interesting. Wondered why it is perpetually unfinished... until I saw the 'Make an off-line version of this book' and 'Make a PDF of the book' sections.

Oh, OK. The authors have chronic obsessive abstraction syndrome, aka Endpoint Avoidance. What a shame.

Anyone have links to an actual PDF of it? Or a zip of the entire 'book' fileset?

A disappointingly indecisive work, dare I say giving a wishy-washy impression. So much more could have been said, if the artist had worked in the far more assertive medium of #FFFFEE. Or perhaps the almost ineffable #FFFFF0.

There's a deeper reason. Remember 3Dfx? They made the entire source code for their 3D hardware available to developers, all in C and a tiny bit of assembler. It could be easily ported to non-Wintel platforms. (I know, because I did port it to a MIPS based platform that had zero operating system. It was a poker machine.)

Then 3Dfx was smashed from the inside and bought out by nVidia. Source code to 3D accellerator hardware drivers never to be seen again.

Why? Because if just anybody could port 3D graphics hardware and drivers to any custom hardware and OS platform, then Microsoft, Apple, etc would rapidly be killed by something with a MUCH better GUI (3D) appearing on the market.

The powers that be do NOT want capable, unchained computing systems to upset their carefully constructed 'enslavement via enshitification' schemes.

Thanks! As an old (retired) programmer I was hoping a good intro to GPUs would turn up. Now, I don't suppose you could add 'ink on paper' to the color options? Gray on light gray, with medium gray highlighting, is hard on old eyes. While I never want to see P7 phosphor green again. And I suppose a zipfile of the whole thing, for local reading and archive, would be out of the question?

Funny! A lengthy review of writing implements, and comments about them, without a single mention of mechanical (clutch) pencils. Like the Pentel P205 (0.5mm leads), and various other sizes of pencil and leads available. Vary the lead diameter and hardness to suit the use. Personally I use 0.5mm, 2B almost always. For technical work, where it's nice to be able to erase mistakes, they're perfect. For daily personal note taking, the erasability is fairly irrelevant.

Now mechanical pencils are so cheap you're best to buy dozen packs (because although they last forever you will lose them now and then), and the leads can be bought cheap in very large quantities via Aliexpress and such. Don't buy leads in the tiny. expensive packs from local stationers.

I don't think you'd be able to get any new non-computerized car at all today. Emission control makes computerization an absolute requirement. That's why choice in cars for people who feel the way I do is limited to old cars from pre-90s. Suits me fine.

Servo power steering is acceptable, though my present car (1993 Subaru stationwaggon) has direct steering, and I prefer that.

I'm a retired electronics design engineer and embedded programmer, and I will NEVER own a car with any kind of vehicle/engine management computer. Old cars for me, forever. I flatly refuse anything but fully manual and direct mechanical gears, clutch, steering, brakes and throttle.

Curiously the chief engineer I knew at a major car service center, also felt the same way.

And that's not even touching on the insanity of building computerized vehicle systems with always-on GSM data links to the Net. Ask Michael Hastings how that worked out for him.

Also I agree that critical systems software should be legally required to be open source.

"There is a button on the remote to activate voice."

More likely: There is a button on the remote to make users believe they have the ability to disable voice data relay to someone's remote servers.

What are the chances such TVs will have network controlled power-up capability? You only think you turned it off.

It's funny that people seem to be accepting always-on GSM network connectivity of the electronics in control of their cars, but oh my god, not the TV!

The TV can't drive you at 100MPH into a palm tree on remote command.

Just to be clear, I think 'smart TVs with network connected microphones' is a completely insane idea. Another on a long list of hanging offenses.

In the videos you can see the quality of the rocket flame changes suddenly about half a second before the obvious explosion in the engine area. The jet becomes more orange and less convergent. At 1:03 in https://www.youtube.com/watch?v=aL5eddt-iAo

So, as a general comment, something bad happened with the gear that pumps fuel into the engines in the right proportion. Maybe involving a major leak of fuel into the structures around the engine. Leaked fuel explodes. Complete loss of thrust, rocket falls back to earth.

I wonder if the Russians would consider it a good or a bad thing for them, if the West decides to stop using those Russian-built engines? Specifically, who benefits if there's a series of failures of AJ-26 engines? Considering the current imposition of economic sanctions against Russia, based on quite untrue accusations related to Ukraine and MH17. The Russians are feeling considerably put out over that, and rightly so.

"all the events of the last week seem so orchestrated that it is hard not to be cynical"

Uh... make that the last 51 years. If you only just noticed, you're not paying attention. And I only say 51 years from picking an arbitrary point (JFK assassination) for when the deep state's evil ways became really obvious.

"If the people were to ever find out what we have done, we would be chased down the streets and lynched." -- George Bush, cited in the June, 1992 Sarah McClendon Newsletter

"We'll know our disinformation program is complete when everything the American public believes is false." -- William Casey, Director of Central Intelligence. An observation by the late Director at his first staff meeting in 1981. This observation reveals the mentality of cynicism which infests the US Federal control structures, and the reality that these structures regard the American people with total contempt.

Fascinating. Presumably it wouldn't be possible for any planets to be orbiting in the vicinity of the 0.258 days orbital period binary. Or maybe, if far enough away?

However, imagine being a species on such a planet, and trying to work out astronomy. Motions of objects in the sky would be rather confusing. To put it mildly.
