It's the other way around. Think about it, how would the oil travel to the rest of the tool that's not touching the felt?

Felt is bad, it wicks away oil from the tool's surface and often absorbs moisture from the air. Tools placed on clean felt will often rust where they touch the felt.

You need to mitigate its wicking and hygroscopic properties by applying lots of oil to it. Use rubber mats instead.

This rule is one of the worst ones, often resulting in nonsense titles or grammatical problems.

Another one on the homepage right now: "Samba Was Written". Ok, great.

It was very thin, sewed into a 'wife beater' undershirt. You wouldn't notice it even if you're looking at it. In fact I'm pretty sure it was sold for the purpose of cheating on exams.

Wow the kids with my new found gift of telepathy. Plugged it into an iPhone mini-jack.

It was meant to be part of a roulette wheel prediction computer that never came to full fruition.

Not embedded, just dropped into your ear canal.

I bought it maybe 15 years ago on eBay, so it's nothing new.

You can use a 9V battery powered amplifier with a loop around your neck to make a tiny permanent magnet placed in your ear canal vibrate against your ear drum.

It doesn't generate hi-fi sound, but speech is remarkably clear. Great for magic tricks. Or cheating at exams I suppose.

> Magnetic North: Shortest surface line to the magnetic north pole (simply in the direction of the compass at your location).

Magnetic North is the local horizontal direction of the magnetic field. But that doesn't generally coincide with the shortest surface line (geodesic) to the magnetic north pole (however you define that - there's several).

If you followed your compass you could end up in a loop without reaching the magnetic north pole.

The author has done ~3 years of commercial work porting game engines, so that makes me add a lot of credence to the article.

A font is designed to have certain attributes (e.g. harmony between the letters). It is not clear that this harmony is preserved if you distort the font algorithmically. For this font the designer ensured that it is preserved.

Compiled to bytecode.

Are you aware of https://machinations.io/ ?

They have written some good books too.

I especially like 'Quantum Mechanics and Experience' by David Z Albert (he's got a very peculiar style of writing that I enjoy), and 'Quantum Non-Locality and Relativity' by Tim Maudlin.

Not easy reading, but manageable if you have a physics degree.

It helps to set the zoom to 200% in the menu bar.

This would actually be more readable if they'd put the em dashes back in.

I tried it and it works. The animation uses belts that are very flexible. With a real belt I needed to give it a shake to make it untwist itself, but it does work.

It is indeed easy to twist the belt until you have the hang of it.

I think the animation is a bit deceptive because even with elastic bands you'd have to provide some way for the correct untwisting to occur. In the animation it happens 'automagically'.

This can't be the original source code.

Original source, I imagine, would be very tersely commented, if only to fit in memory / floppy, and would have very short variable and subroutine names, and lots of mess and commented-out lines from experiments.

This looks like a very lovingly done disassembly.

> Omega allowed swatch to clone their work of art timepieces

Aren't they both basically brands owned by the same corporation (The Swatch Group)?

Swatch released a quartz version of this by the way, in a composite plastic+ceramic material:

I had to edit the title to fit the HN character limit, hopefully I got the gist of it.

One of the researchers tweeted:

"Pretty much the whole industry (incl. @Google Fit @Apple Fitness+) assume that 1 minute of vigorous activity = 2 minutes of moderate activity, in terms of heart health value. Our UK Biobank analyses show that they may be far off, e.g. 1 minute of vigorous = 9.4 minutes of moderate = 94 minutes of light intensity activities, in terms fo type 2 diabetes risk. 1 min of vigorous = 7.8 mins of moderate = 73 minutes of light, in terms of CVD risk."

From reading this it seems to me there is a wide gap between what happens at the molecular level and the social level, and they are very eager to jump it?

Or rebuild the cooling technology to fit the new and future climate instead of the old one.

And some synthesisers in the Pocket Operator series: https://www.linusakesson.net/music/po-2x/index.php

You'd probably get into lunar orbit before descending to the surface, so that would offer you an opportunity to see the Earth rise (sort of).

What do you object to, the color or the texture? Note that 'bone white' pigment used to be made by burning bones.

Yeah, those heckles are added in post IMHO. Microphones don't work that way.

> Fabian Cancellera was widely suspected of mechanical doping

I don't think the opinions of these fringe conspiracy theorists were ever widely held. Not in the cycling world, not among people with an understanding of physics, and not among the general public.

The comparison between the original and the starling's version is at 16:47 in the video: https://youtu.be/hCQCP-5g5bo?t=1066

It's not darkened on purpose, but as a result of containing electromagnetic radiation shielding.
