Rather than the normal solutions, it would be really nice to just move to a progressive consumption tax. 1) All investments are tax deductible, not just 401Ks. 2) The sale of investments is treated as income. 3) Money from loans is also tax

Once upon a time Real World Technology was even better, but met the same fate. If you can write these sorts of reviews you can make much more money as a consultant than from a website.

More details on how RISCy or CISCy various chips are: https://userpages.umbc.edu/~vijay/mashey.on.risc.html Notably x86 is one of the less CISCy CISCs so it looks like there might be a happy medium.

The biggest divide is that no more than a single exception can occur in a RISC instruction, but you can have an indefinite number of page faults in something like an x86 rep mov.

In order to have an instruction set that a student can implement in a single semester class you need to make simplifications like having all instructions have two inputs and one output. That also makes the lives of researchers experimentin

>According to the researchers, the findings underscore the importance of regularly cleaning microwaves to reduce potential health risks, particularly in environments where food is handled. Does that follow? I'd expect that as organ

Earth is lucky to have a strong magnetic field and ozone layer limiting the loss of hydrogen to the solar wind. Mars, for example, has lost much more of its allotment.

It's better to analyze this in terms of the incentive of the particular project managers at Boeing making this decision, since Boeing itself isn't a person making decisions. They might rationally conclude that it might go well an

The usual story is that academia finds an interesting mechanism to produce the desired effect. Though occasionally this is done by industry instead. Then industry turns that into a specific molecule that can enter the human body in a stand

Just as importantly, most values in critical dependencies happens via the bypass network, forwarding from one execution port directly to the next without ever making the round trip to the registers.

Chemosynthesis often does produce pure sulfur as a byproduct but so do volcanoes. a priori I'd put the most likely scenario for Mars at chemosynthetic life with photosynthesis never evolving, but this press release doesn't real

There was one study back in the 1940s(?) that justified it. The researchers who did the study intended it to include water that was in the food a person consumed but the person doing the press conference didn't know that and so respon

I wonder if not being shielded by the Earth's magnetic field during full day would lead to a different balance of isotopes deposited by the solar wind.

Or that have very limited land, or don't have much sunlight. Australia is not the place I would try them, but they may or may not work somewhere else.

A tiny amount of die area, a huge amount of engineering and validation effort. If segmentation issues can cause the register renamer to lose track of who owns a physical register that's the sort of issue that's terrible to find a

Sounds similar to what NVidia was doing with their Project Denver cores, using a mix of emulated ARM and native VLIW instructions with gradual compilation from one to another.

It also applies selective pressure on your population of mitochondria which can reduce the prevalence of deleterious mutations and make them more efficient on a population basis.

It's just that I have a hard time imagining that there were seas without any rain occurring for hundreds of millions of years so it didn't occur to me that these could be separate questions. And most of the comments here seem to

I'm confused by this. When I was blogging about life on Mars[1] I was using a date for the emergence of fresh water on Earth of 4.4 billion years ago(bya)[2]. But this article says the date has been pushed back from 3.5 bya to 4.0 by

If there's a subsequent population replacement the estimate will thrown completely off. Edit: And to be clear, not all population replacement is violent. The Norse in Greeneland were gone when the Inuit showed up for instance.

NVidia doesn't have a general advantage in hardware design skills, but they have been focused on AI workloads for quite a while while AMD spent a long time focusing on HPC factors like 64 bit floating point performance.

Wouldn't the e/acc analysis here be that if people, or our entire species, has to die in the name of progress then that's a cost we should be willing to bear?

I've had thoughts along the same lines, but this would require big changes in kernel schedulers, ELF to provide the information, and probably other things.

It's also a matter of workload. For a database where threads are often waiting on trips to RAM then SMT can provide a very large boost to performance.

Yes. I think its laudable for a department to bear DEI in mind, but requiring every individual professor to work towards it too is frankly a bit totalitarian.

It's exactly the potential for side channel vulnerabilities that makes SMT so hard to get right.
