Wendelstein 7-X broke yesterday its own record with the 100 s discharge duration and ca. 400 MJ total energy injected into plasma.

This infrared image shows almost no thermal loads to the first wall, i.e. plasma is well insulated from the surroundings, which is essential for a future reactor. We call such state of plasma - detachment. It allows for longer operation of the reactor.

With 100 s plasma duration this is probably a world record for the duration of the detachment. (C) IPP

We plan to reach 200 seconds by the end of this campaign with 1 GJ injected into the plasma.

1000 out of 1200 kids in this school in #Oulu, #Finland, arrive by #bicycle, even in winter. 100-150 walk, rest by ski, kicksleds and car. This day it was -17°C, some days it can be colder than -30°C.

Note that this is only one of the four bicycle parking areas of this school 🤗

Desert Bighorn Sheep. Goler Wash, Death Valley National Park, 2021 I was off roading as it was a Sunday and no planes were flying. I decided to head up the wash to the Barker Ranch (where Manson was caught) and it took about 3 hours to go ten miles. Saw no life on the way there but was treated to these beauties. #sheep #DeathValley #wildlife #animals #photography

I've read that our bodies contain tens of trillions (10 raised to 12th power) of cells! Each one has a mind of its own and wants to survive badly. Of course, there are bad actors who go rogue and cause havoc.

Trillions enclosed within multi-layer cells called the skin. We are nothing but a sack of cells.

Oh, yeah, you guessed right, I'm just reading "The Song of The Cell" by Siddhartha Mukherjee.

Listen to his interview on Fresh Air.

Semiconductor history 

@groundie Thanks for the info. I interned at Intel in the mid-1980s but don't recall the 4004 being mentioned.

I was there when the 80286 (or just the "286") was the hot new generation, the 8086 and 8088 were the bread-and-butter standards (excluding microcontrollers like the 8041, 8042, and 8051 series). The 80186 and little-known 80188 were compatible with the 8086 and 8088, respectively, but included core motherboard features like the interrupt controller on the processor chip.

That was also the time of Intel's 432 processor, a microcoded CPU that directly executed Smalltalk bytecode for object-oriented programming (OOP). The 432 was an interesting idea but failed massively in the marketplace because its microcoded architecture on a CPU core of that era was simply too slow to be viable for real applications.

This may be old hat to the entire universe, but I just discovered "Horizontal Scrolling" just 'cause I've got many Mastodon columns (8 and counting).

The Shift key is the secret. With a thumb-wheel, it's downright fun!

@groundie Or switch to a different theme which doesn't have tickers included.
@khird

It's taking up to 10 seconds for qoto.org to load! Yes, I've checked and it is just qoto that is slow. Other sites load fine and the issue occurs with any browser.

I suppose it's the influx of new users.
