I was hoping that might at least get a chortle or two. ;)

Not really. Most every hardware shop has them these days. Amazon is about my only other source, but quality/usability is a gamble in the M1-M2 range for some reason. The number of small bolts and nuts in that range that are cast badly seems to be high for me. That seems really odd, actually.

Kits are the way to go, usually. I have a full assortment of nuts and bolts from M1 up to about M6 at many different lengths. I started building a collection when I was modding 3D printers but use them for any other random project these days.

Edit: Local hardware shops generally carry decent assortments from M3 and up. It's more expensive than Amazon but is great if I only need one odd larger size for something random.

The occasional shit-loads, sure. But dealing with metric fuck-tons is a pain in the ass.

I am converting my life to metric, actually. All of my CAD work is in metric and all of my chemistry glass is thankfully in metric. Thinking in longer distances is something I need to get used to though.

The imperial system is just a waste of time, TBH. I am sure there are a ton of people that can work fractions in their head but I just gotta ask: Why, and what is the point?

Measuring and planning with metric is just so damn easy and no extra steps are generally needed. When I need to convert 1000mm I just move the decimal over a bit and get 1km. EZ.

This bubble is quite bubbly. There is an AI company for anything and everything now. The market is almost fully saturated with "AI" everything.

Just like the web bubble, all of the intsta-AI shops need to fail so the real tech can grow. AI is never going to go away, but most of the scam companies will fail in due time.

We might have one big consolidation, or several. The hype will die and the quick money will disappear. It's the same story, every time. One the magic AI box stops shitting out dollar bills, we should be good.

10 mg/70 kg, 3 doses, 5 days apart each

That is a fairly mild dose. It's enough for many people to catch a buzz, but it's not going to send them on a tour of a neighboring universe.

It's good to see a study on moderate/low dose applications, actually. The stress relief alone is probably great for a ton of other conditions, now that I think about it.

How the heat is generated is still wicked-cool and is basically magic. Think about it this way: We are holding a toroid shaped micro-sun in place with magnets. Those magnets need to be adjusted hundreds of times a second to keep everything in its place. Sure, it just boils water, but how it boils water is where the real magic is.

We are building atoms by taking control of the core of a star.

It's likely going to create steam, just like a reactor today. It is a very effective way to turn a turbine for a generator, after all. All the bits that actually start and maintain the reaction need fuck tons of electricity, so the reaction can literally power itself when attached to a generator.

While there are a ton of formulas for converting energy from heat, to steam, to mechanical energy and then into electricity, it's all basically the same: more power out than you put in is a good reaction.

Almost forgot, water is dual function. It cools the equipment and it acts as an energy transport. I believe ammonia is more efficient in some circumstances, but water is better for obvious reasons.

Yeah. Actually using that heat is the next challenge, I suppose. If I am not mistaken (and I am often mistaken), they are not actually using the reaction to power the reactor yet.

It's all math, basically. If they measure more energy coming out than they put in, it's considered a win.

(The article touches on this bit a little) I was watching something about fusion the other day and it seems that it is super tricky to keep the magnetic field balanced in a way that keeps the plasma in a proper toroid. Not only does it need to keep the correct strength, it has to fight against random turbulence. This is critical to start the reaction, but also to maintain it.

Also, they gave some other physical limitations in the article as well:

To extend their plasma's burning time from the previous record-breaking run, the scientists tweaked aspects of their reactor's design, including replacing carbon with tungsten to improve the efficiency of the tokamak’s "divertors," which extract heat and ash from the reactor.

Basically, it's the container that has limitations as containing a pseudo-sun probably isn't easy.

It's not destructive, nor can it really be considered illegal access. I suppose there is something illegal about it if it's classified as a DoS, I guess. There isn't much on a payment PED aside from an encryption key and maybe some network information.

Entering your PIN and accidentally hitting 3 buttons hardly seems like something to get charged with. How you leverage that for other things could easily be a problem.

All I am saying is that the likelihood of serious repercussion is very low. Still, I have to agree: Only do it with permission and with purpose.
