That why the solution is to only allow speculation when it's "ok". M1 is believed to have a number of Spectre-esq security mechanisms built into it to determine just that. For example: https://patents.google.com/patent/US20200192673A1
Also, In dougallj's code [1] the zero of registers should be superfluous so it is assumed the function below is needed to make the experiments run stably by claiming ownership of the registers as part of a general anti-speculation security mechanism.
static int add_prep(uint32_t *ibuf, int instr_type);
The M1 explainer [2] has lot of interesting ideas like this contained inside it.
> Again, I'm not interested in an OS flamewar. That Apple's products are subpar is a fact at this point
That second sentence seems like it was specifically crafted to start a flame war to me. You don't even mention on what dimensions Apple products are subpar. All possible ones I presume?
> Is the correct value for a Ponzi scheme really determined by the most recent dollar they took in?
I wouldn't say a Ponzi scheme should be valued by this dollar. It should be valued by the next dollar that someone is willing to put into it as the whole point of the Ponzi scheme is to gather the next dollar.
I think most stalls are actually shared so when your neighboring stall is occupied you'll get less power. Stations are more crowded these days so it's getting common. Anyway, it doesn't actually diminish your argument, especially as 16-pod+ supercharging stations exist.
The complex plane was introduced by Caper Wessel in a paper that was published in 1799 so it would've existed before vector notation.
My guess is by the time vectors got popular the complex notation, and theorems that people had proved which used complex notation, had already stuck. But I'm only a hack math historian so I can definitely be wrong here.
I think it's important to keep in mind that math and science, much like the code base that I am trying my hardest to avoid, is evolved.
I really enjoy looking into the history of mathematics and physics. I think it gives one a much better appreciation of why things are defined the way they are, and also the limitations of those definitions.
There is a really great book on the history of imaginary numbers. The history mostly focuses on how i was used to help solve algebra problems, so definitely one should be comfortable with high school algebra to get something from the text, but I don't think one needs much more math than that for the first half of the book. The second half gets more into how various use cases developed, in those chapters basic college level calculus would be a major plus. I read it more than 10 years ago though so no promises. :)
>> homework
> This is one issue that I'm passionate about. Research increasingly implies that homework is probably harmful in elementary; of dubious value in early middle school; and only valuable in high school and beyond.
Isn't the article about removing homework in high school?
Mr. Moreno, the Alhambra High School English teacher, specifically said he no longer gives homework. Doesn't this mean the research indicates he is removing something valuable?
It might all be semantics though.
I assume the "opportunities to improve essays and classwork" is done outside of normal class hours. Perhaps, the work is done at home. And that they addressed your point A by allowing students to resubmit work, and your point B by removing deadlines. I can definitely see how it could be an improvement.
I think it probably depends on what "produced" means here.
If it means designs inside an EDA environment, design get submitted and shows up realized, then that is possible now. And it's not all that expensive. eFabless chip ignite is quoting ~$10K for 100 QFNs in 130nm. That's getting into beater car territory. https://efabless.com/chipignite/2110C
If it means actually fabricate then I think there is no way because a DIY won't have the scale to compete on price and they won't be able to bring any custom processing step to justify being at boutique scale. Think about PCBs. We used to make them ourselves with chemical etch. Now I don't even use breadboards because a custom bare fab is $5 and the components cost more than that. I also get a much better electrical result, and it doesn't fall apart if I look at it funny.
The main problem with ASICs is the amount of skill/time that it takes to do it right. Floor planning, track planning, closing timing, etc. etc. on an ASIC is much harder than an FPGA. You don't even have to do half those things on an FPGA.
With an FPGA one can almost get compile and go if you're willing to be loose on area and performance. ASIC CAD tooling is no where near that at the moment. Closed or open source.
Was it in California and what year was it? It's well known in the valley recruiters from various companies put the kibosh on many offers to prevent talent from moving around. There were some big lawsuits on it.
> Also, putting the emphasis on the interviewer understanding the candidates code instead of the other way around is never going to be popular
It's also hard to scale it, make it objective, and keep the efficiency high (most developers prefer not spending their time on either side of the interview table)
There is another advantage to the "algos". If you can learn algorithms then perhaps you can learn other things as well.
Every new job I've had involved quite a lot of learning in a very short period of time.
Learning whatever language, and whatever standard library is almost always trivial. They're usually not all that different, well documented, some with textbooks even.
Learning to navigate and reason about the huge number of undocumented, often arbitrary, system architecture decisions, design decisions, code layout, etc. etc. that make up real code bases.
