nomel··on Jobless tech workers are being left out of San Francisco's AI boom
> not have upskilled significantly in such an intense environment

Those that passed would have still remained ahead, from their continued improvement.

nomel··on Apple reports fourth quarter results
They're not building on someone else's platform as much as leasing completely commoditized compute from whomever gave them the best deal. I wouldn't be surprised if this compute will actually be happening on xAI hardware [1].

We've gone (mostly) full circle.

> Not all technological innovations involves a failed attempt at commercialization

My original comment:

> Do you have any good examples of tech that was immediately embraced without any prior examples or failures to monetize?

No goal post moving on my part.

Not sure I understand the MS tablet example, since it seems unrelated to the sentence before it (going against it).

It's is usually a deal breaker if used for room lighting, rather than display lighting. Especially where food is involved. Try swapping you dining room lights for RGB.

There are many millions of devices connected that draw power, and increasingly so, supply power.
nomel··on Radiation Map of the World
Or they zeroed in on something interesting, since finding interesting radioactive bits is the primary use of the device. One I saw in CA was confirmed to be a uranium deposit, by geological survey, on a random trail near some houses.

If you don't believe any of this naturally occurring phenomenon for some reason, there are several YouTube channels that check out these places, and try to find their own high activity areas/objects. There also subreddits dedicated to it,'and even a map where you can find places! ;)

For big orders, you make sure that there's something involving "actually receive what was purchased" in the contract. For little guys like us, absolutely nothing you can do, except pay a way more and buy from a reputable vendor that does these checks on their side of the sea/has big purchase deals with contracts that protect them.
nomel··on So I guess everyone uses LLMs to think now
Let's say the average sentence is 17.5 words, with the average word length being 4.5 characters. Not capitalizing the first word is only a 1.27% character error rate, on average. Not too bad. ;)

Not sure why this is downvoted. It's simple color theory, and the whole reason the CRI measure exists.
nomel··on It's the memory latency, stupid
My general rule of thumb is that if you see you can 2x it easily, you can actually get somewhere around 10x with effort, since the presence of that easy 2x means nobody really spent any time on performance.
nomel··on Much Ado About None: Sentinel Values in Python
How are these two things related? If you don't use exceptions, you just have to implement them yourself by manually bubbling up the error, all the way up the stack, rather than using the dedicated side channel to do so.

The problem I see is there's no way to enforce the check that you actually handled/bubbled up the error. With exceptions, you just crash if you don't handle it, which is much preferred if determinism is the goal. Is there some way to use the type system to do this? Maybe incoming are UnhandledResult outgoing are some HandledResult or something like that?

nomel··on Much Ado About None: Sentinel Values in Python
Very many people have been taught that exceptions are bad and should be avoided, because google avoids them.
nomel··on Much Ado About None: Sentinel Values in Python
I feel like faster exceptions would be a better solution for this sort of thing. Leave functions returning the happy path with excepted values. Exceptional things, like missing values being handled at the level where of abstraction that actually cares to catch it:

nomel··on UK Green party drops longstanding opposition to nuclear power
I drove through Nevada recently and it made me angry how much flat, high sun, land there is for solar, with no real environmental impact whatsoever (probably improvement for local life from the bit of shade).

I could see this maybe working using a standardized sensor reporting system that goes into some third party/government/public analysis. Full sensor array stream, and whatever is used internally to make decisions, up for scrutiny.
nomel··on Sam Altman Thinks You're Wasting DRAM
99.67% of seawater can't be used for fusion. Some very poor napkin math, that's around 1.3 million cubic miles, with around 2200 cubic miles per inch of sea level, which is around 600 inches, or 50 feet drop in sea level if fully depleted (not including any sea level rise from global warming).
nomel··on If IPv4 were land
Is this fundamentally from poor routing from infrequent use? For example, if usage was 50%, would the routing/hops between the two somewhat converge? Or is this actually a "v6 is hosted on a separate server somewhere else" type problem?
nomel··on SIMD-accelerated computer vision on a $2 microcontroller
This is a very hard problem, when working with china, in any capacity. There are whole teams dedicated to this, in larger companies. Usually, it involves IQC where you sample the devices, X-ray them, and verify things are correct. There's also neat thermal methods: https://ieeexplore.ieee.org/abstract/document/11038103

> ... blockchain - was about an explicit race over who could waste the most computing power on nonsensical calculations.

A hard rule of life is, if there are resources available, something will consume them. It's interesting that this also ended up being true for compute!

The same link shows that a video was also put on his CD in the 70's!

> Their efforts led to a 20-minute video disc in 1973.

> In 1974 Digital Recording Corporation announced ... the first device to digitize a color image, at a Chicago trade show. The response from large potential investors was rather cool.

And, there's LaserDisc, of course (although analog, unlike the digital disk in the above), which was somewhat of a flop (the ridiculous dimensions being part of the cause).

Tangentially related, BlueRay was more about just waiting for a blue led to be invented, than some new disc tech! [1]

[1] There was a really great youtube video about it, but can't find it. Se here's a bad generic recap: https://ssleec.ucsb.edu/news/nobel/professor-shuji-nakamura-...

I know little of this. How/why could one be higher latency over the other?
nomel··on H.264 Is Magic (2016)
Sorry, but it's only apple to oranges if you already know the answer. That answer, explained in the next section, is very clearly intended for someone who didn't already know it:

> This concept of throwing away bits you don't need to save space is called lossy compression. H.264 is a lossy codec - it throws away less important bits and only keeps the important bits.

> PNG is a lossless codec. It means that nothing is thrown away. Bit for bit, the original source image can be recovered from a PNG encoded image.

nomel··on H.264 Is Magic (2016)
Yes, as they explain shortly after, in the next section "shedding weight".

They're not actually confused here. It's a writing style, where you pose an interesting problem/scenario, then explain it.

Nope [1]. Starting in the 70's, with:

> However, like many ideas far ahead of their time, the CD-ROM found few interested investors at first.

And then in 1975:

> Philips Electronics representatives visited Russell’s Battelle lab in the summer of 1975, and they discounted the entire premise of his work.

nomel··on Evidence of a spying operation by ICE against left-wing social movements
I'm having trouble believing this comment chain is happening/neccesary. I feel completely disconnected from the thought process of a large portion of society.
