The optical stuff is still research territory and too early to be comparable to the current digital silicon. Lots of open questions about how to implement multiplication, implement activation functions, where to store weights, how to move d

Sounds interesting, can you say who it is?

The key idea is you can use physical effects such as attenuating light to implement multiplication in a way that uses much less energy than the fairly complex arrangement of digital logic necessary to implement the same operation. This is r

There's no product doing this yet but it seems likely we'll end up with cryptographic mechanisms to enforce the integrity of the security-critical processes offloaded to third parties.

I spent some time trying to get them to do this for a previous startup back around 2017 but their view at the time was essentially that a couple interns and/or "the community" would solve the problem. At a higher level I thin

There are a few different ways I've read about far UV being deployed, one of the interesting ones is illuminating the upper few feet of a room. Exhaled breath tends to rise so apparently doing just the top of the room is more effective

According to the linked article: "While the effects on live tissue are diminished, Far-UV (222 nm light being the most prevalent) has increased efficacy for killing bacteria and viruses."

They had bomb sights of various complexities, the Norden being the best known US design: https://en.wikipedia.org/wiki/Norden_bombsight Still very difficult.

They are less common but available, I have just recently been looking at options that will do combined hydronic heat and hot water for the taps. The hardware isn't too expensive but the labor for that kind of install can be a lot (high

Relative gas/electric pricing may be a lot different where you are. In the Seattle area gas is around $1.20 per therm which works out to about 24 kWh of heat per dollar. Electricity is around $0.11 per kWh or 27 kWh heat per dollar ass

The way to do it is probably to colocate the generator with the condenser unit and use a thermostat-controlled second loop to move heat to/from the main refrigerant loop as needed. This gives some options to keep the generator from get

It also means that there's a fixed target that can get an extended amount of testing in the field, and when fixes for that version come out you know you're getting issue X fixed but no other change in behavior. Less chance of inci

There are both, and they are related. For example family wealth and wealth accumulation in the US is weighted heavily to home ownership and appreciation, the GI bill that powered a great deal of home purchases was structured to exclude blac

In the US discrimination based on skin color is widespread and goes back to before the country's founding, and access to opportunities is very uneven based on wealth. The PoC term is a reflection of the general pattern of discriminatio

What does equal access mean? If I go to an all purple school, and focus my sourcing fro new hires on my school, then my company will by construction be more purple than the overall population without any explicit discriminatory treatment af

A historical existence proof of a system or technology working has essentially nothing to do with whether it's being practiced in industry today, and whether it's being practiced today has very little to do with the product or pri

There are some wrinkles to this: First, big cores are less efficient per unit work because there's a lot of complexity in things like reordering, speculation, and pipelining and that complexity costs energy. A design optimized for peak

In the last few years this is pretty much where we've gotten to. Sometimes I leave Activity Monitor open on my M1 Mac and the four little cores keep the big cores mostly idle until there's a lot of work to do (a build or sigh sc

What I'm getting at is things like applying fertilizer based on estimated need from imaging data, using robots with lasers to kill weeds, mechanized intercropping, etc. Not something consumers will necessarily see any direct impact fro

Like the rest of industrial age development, farm automation has historically been built around treating everything uniformly (even distribution of seeds bred for easy harvest in evenly spaced rows evenly fertilizied with no rocks etc etc).

I don't know if this report is real but nobody with significant experience dealing with Intel would be surprised if they do choose this particular footgun configuration.

I think the decisive advantage of dividends was that buybacks weren't legal until the 80s.

The camera software on the 14 Pro is pretty bad, so that's part of their problem. Almost enough to make me return mine.

Your math doesn't line up at all with the numbers you linked for the 13" Pro, and I've not mentioned anything about 200% (or 2x which by the way is different), so let's look at the real numbers. A 50%+ perf bump after a

Let's base our opinions on facts. Taking the 13" Pro example the annualized growth in single thread performance from the 2008 model to the last Intel model is about 13.2%. The increase from the last Intel to the M1 model was about

I'm not sure what's up here but I think the points you're making in this thread are mostly opposite reality. Each of the M1 products has been a big step up from the preceding versions in almost every respect and especially pe

I'm not sure this is true, looking at say the i7-1260P in the XPS 13 it appears to turn in performance similar to the base M2 and half the battery life. M2 Max is twice as fast as the i7 and still 2x-3x the battery life, though also tw

I used to travel a lot and lost, delayed, and damaged luggage was a recurring problem. In one case we had to pay a local expediter to go get our stuff.
