No magnetic confinement fusion reactor in existence has ever generated a positive output. The current record belongs to JET, with a Q factor of 0.67. This record was set in 1997.

The biggest reason we haven’t had a record break for a long time is money. The most favourable reaction for fusion is generally a D-T (Deuterium-Tritium) reaction. However, Tritium is incredibly expensive. So, most reactors run the much cheaper D-D reaction, which generates lower output. This is okay because current research reactors are mostly doing research on specific components of an eventual commercial reactor, and are not aiming for highest possible power output.

The main purpose of WEST is to do research on diverter components for ITER. ITER itself is expected to reach Q ≥ 10, but won’t have any energy harvesting components. The goal is to add that to its successor, DEMO.

Inertial confinement fusion (using lasers) has produced higher records, but they generally exclude the energy used to produce the laser from the calculation. NIF has generated 3.15MJ of fusion output by delivering 2.05MJ of energy to it with a laser, nominally a Q = 1.54. however, creating the laser that delivered the power took about 300MJ.

Sort of, browsers can run rust code through webassembly. But i dont think this is a full replacement for JavaScript as of yet.

They are emissions credits. Every company receives some amount of “CO2 emission credits” from the government. These allow you to emit a certain amount of carbon dioxide. If you don’t emit all the CO2 that your credits allow, you can sell those credits to other companies that need more than the government gives them.

The idea is to put a total limit on the amount of emissions in the country, while letting the market figure out where it makes most sense economically to invest in emission reduction.

Tesla makes only EV cars and so it doesn’t need all the credits a typical gasoline car company would receive. So they sell them.

I had one in high school. The design was kinda gimmicky but the phone had good features for its time. it had an FM radio receiver, and I remember you could even transfer MP3 files onto it, although it was a hassle to do so.

I advise everyone to ignore this article and read the actual paper instead.

The gist of it is, they gave the LLM instructions to achieve a certain goal, then let it do tasks that incidentally involved “company communications” that revealed the fake company’s goals were no longer the same as the LLM’s original goal. LLMs then tried various things to still accomplish the original goal.

Basically the thing will try very hard to do what you told it to in the system prompt. Especially when that prompt includes nudges like “nothing else matters.” This kinda makes sense because following the system prompt is what they were trained to do.

The very first sentence of the article answers these exact two questions.

There’s a lot of stuff that isn’t really efficient to own individually. I need a power drill one day a year or less, it’s just gathering dust in my closet the rest of the time. I bet most of my neighborhood does the same.

I often dream of a local community center of sorts that lends out tools, and other such things, maybe for a small yearly fee. They could spend to get something robust, good quality that lasts for a long while. And the whole neighborhood could benefit. Sort of an expanded version of a library? I guess none of that is very profitable.

It’s really about quality imo. Not all 4k video is equal, and streamed video tends to be especially bad. It’s possible to download decent quality video files, but they are all from blue ray rips. If blue ray goes away, streaming sites might be the only remaining source for digital video files, and high quality digital video will essentially die.

The question what this area represents is left as an exercise to the reader.

https://what-if.xkcd.com/11/ is relevant.

Rigor in definitions allows us to express a lot of complex things in a compact form. this allows us to treat “Cars” as something different than “Motorcycles” while both a motorized vehicles.

Meh. There’s plenty of room in the gray zone between “car” and “motorcycle” where things like this or this can exist. The botanical world has worked very hard to create rigorous definitions of fruits and vegetables only to be completely ignored by cooks. The culinary world in general has done just fine for centuries without rigorously specifying whether taco’s are sandwiches and cereal is a soup.

As long as it is generally understood what people mean by a word when they use it everything will be mostly fine. REST is an understood term, whether the inventor of the term meant something else by it is immaterial.

I think people exaggerate how bad QWERTY is. Studies have not consistently found an advantage for one keyboard layout over another, and some studies even show that typists can reach equivalent speeds even with randomised layouts. This suggests that experience and practice with a particular layout is far more important to typing speed than the particular placement of letters. Which is a good argument for keeping qwerty around.

(reducing the risk of mechanical typewriters jamming by not having two hammers next to each other be pressed at the same time),

This story is quite common but there is little evidence that it’s actually true. The designer of qwerty actually made a late adjustment to move R next to E (swapping it with period), even though ER is the second most common letter combination in English.

How the mighty have fallen eh? Prince of Persia was a big franchise once upon a time. Like, the Sands of time trilogy was AAA tier.

The big reason I’m hearing in this thread is “Denuvo and I don’t trust Ubisoft.” However I doubt that is the reason the mainstream audience skipped over this game. Ubisoft franchises generally sell like hotcakes, and for the most part only nerds care about DRM (like the type of person who knows what a lemmy is).

It’s hard to say why it didn’t sell more units. Certainly it seems their internal expectations were sky high:

similarly to the biggest Metroidvania’s in the market, with millions of units sold in a relatively short space of time

The game is good, but metroidvania is not exactly an easy market; there’s some juggernauts in that genre, and they came out with a completely new and unproven concept. Apparently it sold a million units or so still, to me that’s not unimpressive.

On PC, it initially launched only on Epic afaik, which certainly doesn’t help. And by the time they brought it to steam it was much too late.

What I don’t really get is, why disband the team? They’ve proven they can produce quality stuff. Just hand them some other promising projects? I suppose that’s too much of a risk for a publisher like Ubisoft.

But python has GIL and you can’t just remove it so

https://docs.python.org/3/using/configure.html#cmdoption-disable-gil

The GIL appears to be slowly going away.

But the game is “finished”. there is no need for alterations.

If only that was the case. But there is no chance a game built for windows 95 could run unaltered on an android phone. Things like the rendering systems, input handling, and sound output will need to be adapted to work on a new platform.

You could, but there isn’t much benefit. The purpose of all that extra information is generally to make the program easier to understand for a human. The computer doesn’t need any of it, that’s why it’s not preserved in compilation. So it is possible to automatically translate assembly to C++, but the resulting program would not be much (if any) easier for a human to understand and work with.

To give a bad analogy, imagine some driving directions: turn left at 9th street, enter the highway at ramp 36, go right when you’re past the burger king, etc. These are translated into physical control inputs by the driver to actually take the car to its destination. Now we could look at the driver’s physical inputs and turn that back into a written list of instructions: turn the wheel left 70 degrees, turn it right 70 degrees, push the gas for 10 seconds, and so on.

All the street name references are now gone. There are no abstracted instructions like “enter the highway” or even “take the second left.” It would be quite difficult for a person to look at these instructions and figure out the trip’s destination. Let alone make some alterations to it because there is roadwork along the way and a detour is needed.

Your thought is correct. The basic problem is that higher level languages contain a lot of additional information that is lost in the compilation process.

It’s addressed in the article. The brave CEO has stated they will continue to support manifest v2 as long as the needed code remains in Chromium. He made no promises what happens when it is removed, though (“I don’t write checks of unknown amount and sign them”)

Fun quote from an interview with Chris Sawyer:

Latterly the machine code came back to haunt us when the decision was made to re-launch the original game on mobile platforms as RollerCoaster Tycoon Classic a few years ago, and it took several years and a small team of programmers to re-write the entire game in C++. It actually took a lot longer to re-write the game in C++ than it took me to write the original machine code version 20 years earlier.

GOG is getting a nice little pr moment off of this but you’re getting basically the same license, no matter where you buy the game.

The root of evil in digital distribution is the DMCA anti circumvention clause: it is illegal to circumvent a DRM protection to gain access to some copyrighted work, even if you in actuality possess a license to the work. This law gives big platforms far too much power to control how you interact with their products.

It should be legal to modify a work to allow it to be played offline, to make copies for archival purposes, to fix the work to run on newer platforms, etc. As long as you have a license to the work you should be allowed to take steps to ensure your rightful access to it.

By the way, the root beyond roots of evil in digital distribution is the insane length of copyrights themselves. Why are patents 20 years, but copyright extends to 120+? The answer is pure greed.
