Sorry, the onus here is on you to provide a single shred of evidence to support the dubious claim that the technology is merely hindered by "details of economics and engineering". Fact: fusion reactions are not self-sustaining.

I would think "not capable of producing a net-positive yield" a pretty compelling reason. The field has been researched for more than half a century and yet to date we still have zero evidence this is even achievable. The limiti

If you break up "mv^2" into its constituent dimensions you get m(d/t)^2 = m(d^2)(t^-2). Now the so-called kinetic energy of the object only "manifests itself" whenever there is a change in velocity of the object i

The ironic thing about all of this hype is that fusion isn't even inherently capable of maintaining a self-sustaining reaction! Unlike fission, which is a chain-reaction process, fusion requires *huge* amounts of energy every single ig

AFAICT this library generates "flat" JSON objects. Wouldn't be too hard to implement it such that references to Javascript objects are instead returned, where some sort of callback could be invoked whenever the actual object

Ah yes, I stand corrected! In that case I suppose more trials really would have made the results more convincing, too....

The probability of guessing all eight correctly is 0.5^8 (or roughly 0.39%). The chances of such a thing happening by mere fluke are quite slim. Now personally, I would have preferred a few more glasses to be even more certain, but hey, f

I think it originates from the observation that all machines "leak" power in the process of performing work. Vibrations, thermal conduction, infrared radiation, etc all tend to decrease efficiency and hence increase entropy (in

The latter, apparently. TBH I answered after hearing about the story elsewhere and it just struck me as fairly benign for an employer to ask as much from a (soon-to-be) former employee. I am not a lawyer anyway so I honestly have no idea wh

It just seem petty, refusing to sign a simple document agreeing to not to trash your former employer (with whom you intend to continue to benefit from a shared interest in said company). It wasn't as if Altman was threatening to take b

FWIW the Collatz conjecture actually asserts the exact opposite, that the sequence always terminates.

While indeed true insofar as there are still many grey areas concerning data collection and use, conflating these issues with "slave labor" and "zombie trainers" is just plain disingenuous. Twisting words around to fit y

Developing robust programs in C just requires a clear understanding of the language itself (and of course a good overall skill set as a programmer). I have been writing (mostly) bug-free code in C for over twenty years. My only real compl

Wait, did I read that right? Are you actually suggesting that climate change is the cause of rising crime rates? If so, please explain, because I would honestly like to know how you reached that conclusion.

Well, I didn't find the art very appealing. But I do love the idea behind it. Neat project!

I don't know, LLM's are very good at embedding subtle changes in their responses. They are also good at researching things like "best possible place to hide bugs", etc. Is it really a stretch to imagine that these tech

by af3d 3y ago
Fair enough. Of course, projects with few retainers will likely not have near as many eyeballs looking over the code base. I do see your point, however, in a sense nothing has really changed. Although the job of maintaining a FOSS codebase

by af3d 3y ago
Well I guess we just have different standards of "cleverness". As far as I am concerned these technologies already demonstrate a level of subtlety that would allow them to be used in such ways, as is. Nevermind six months from now

Well it is true, the XZ hack was a major social-engineering feat. Regardless, we should not be underestimating the power of these technologies. If an LLM can respond to a request to generate code, what makes you think the attacker couldn&

Correct. The current regional concept of "Germany" proper probably started with the Treaty of Verdun, when the lands of Francia were divided amongst three of Charlemagne's grandsons. The inheritor of Francia Orientalis was in

Nice explainer! I wonder, so do these FFT matrices have to satisfy some (dimensional) condition to ensure that an analogue of "3D gimbal lock" does not occur?

Minor typo: "Here’s a surprising property of circulant matrices: the eigenvectors of a circulatnt [sic] matrix depend only on the size of the matrix, not on the elements of the matrix."

That "Climate Change Service" graphic is indeed disturbing. Regardless, the temperature anomaly in the Arctic is in fact currently at or below average (in other words, plus or minus 0°).

No doubt this is an issue that should be taken seriously. But certainly much more concrete proof of declining trends would be needed before declaring such a forgone conclusion. While the extent of sea ice does indeed shift around quite a bi

Tragic, yes. But from a journalistic perspective at least these deaths would probably be more accurately described as arising from disputes over land rights (as opposed to the environmental activities of the victims). Most likely died as a

The novelty seems to be the form-factor. It's energy harvesting made simpler for low-power applications. (A small microprocessor for example, LED's, sensors, etc.)

One solution not being discussed much: formal verification. Any given "critical" IoT software component ideally should be subject to rigorous mathematical inspection in order to verify its logical integrity. Upon passing, it could
