Why would a 1Gbps connection be required for streaming video? Netflix, YouTube, and Twitch seem to be able to service most of the world.

I haven’t actually read the article, so perhaps they say as much. But if so, that’s surprising.

EDIT: thinking a bit more carefully, the limitation is upload speed, not download speed. In that area, the US has been lagging behind in tech.

Still, I wouldn’t bet against it being viable. I remember the first few months YouTube launched. The video quality was atrocious, the worst on the internet by far — this isn’t revisionism; other platforms tried to compete on quality.

Didn’t matter; youtube won. And now we enjoy 4K steaming.
Talking with a Chinese friend of mine, his take was that Jack Ma's imprisonment/disappearance is less about his comments in the October speech and more about an ongoing power struggle in the CCP between supporters of the former General Secretary Jiang Zemin, who is an ally of Jack Ma, and the Xi Jinping faction. The October speech may have just been the catalyst and pretense. As for how smooth the transition would be, Chinese politics are pretty opaque and I'm far from an expert, but from the outside it appears the Xi faction is fairly strong and only growing in power, so I would guess the transition wouldn't be too turbulent.

I definitely think politics are less unified in China that it may appear, and the whole situation with Jack Ma is an example of "multiple power centers bumping into each other".
Unrelated: since when did gitlab turn to shit on mobile? There is so much unnecessary padding, and all the filenames are truncated to four letters:

I read a lot of code on my phone. A lot. Too much. Stuff like this is going to discourage me from even clicking gitlab links.
Schematics only contain a fraction of the information required to reproduce a design. It's like releasing a UML diagram of an app and calling it "open source."

It doesn't matter if you use the same CAD tool or not, there are a variety of utilities for converting the design files. What matters is if you can reproduce and modify the design. That's simply not possible without the complete design files.

You don't release the artifacts of your compiled code and call it open source. You release all the source required to generate those artifacts. Anything short of that is not open and fundamentally mistakes what it means for something to be "open source."
I never would have thought I'd be posting this on HN but it adds to the discussion.

Wow that article has no clue what it's talking about.

It's claiming a lot of extraneous nonsense based on his Annual Performance report (which are mostly nonsense anyway) bereft of any understanding of the units it's talking about.

Well, BBC is much more left than liberal outlet these days, and liberal ≠ leftist. Despite of some similarities and the apparent alliance, there is a number of drastic differences in their views. Take a look:

> Corollary: When Rep. Ilhan Omar ("a frequent critic of Israel") says something, understand that the words she says must follow the Koran or she faces execution for blasphemy. For that reason, she should not be a US House member, and certainly not on House committees. Islam and the US constitution are opposing ideologies.

You were making some… reasonable claims up until this point where you jumped the shark. We’ll ignore for a second she got a divorce which would also have her beheaded in the Koran, and I’ll immediately point out that literally every religion when taken verbatim is incompatible with our constitution. That’s why we have separation of church and state.

This is the big one. But how can Apple ban users for abuse if they themselves cannot know which user is responsible for any particular request? If they can tie individual users to abusive activity then their claims of being a truly private relay service are bogus.
So, your original post was a question, and I answered it.

But maybe your question was rhetorical and masked an overall point you are now trying to clarify. But I still don't understand the point your making!

Are you trying to absolve YouTube of any moral responsibility, while personifying with them with agency ("they have reasons", "they feel like it", "the degree that serves them", "they care") and granting them rights ("1st amendment")?

As for what really motivates corporations - I believe survival, not profit, is the essential goal. Profit is just one strategy - but another is not poisoning it's own environment.

Titanium hydride storage has been tested for automotive use. They shot hydride tanks with a rifle, and the result was less impressive than shooting a gasoline tank.

Also, hydrogen rises quickly as it burns, instead of spreading out on the ground.
Single precision is a 15-bit fixed point number in the range between -1 and 1. Apparently in most cases this was enough for moon flights. There was also double and triple precision that were used sometimes.

Of course, in many places in the code you need values outside of this range and the actual number represented is scaled by some factor. However, the CPU has no internal representation of the scale factor (i.e. the exponent bits in a floating point number) so the programmer had to manually manage this.

I can strongly recommend this book, if you're interested in the AGC: http://www.apolloguidancecomputer.com/
All of your examples limit or prescribe hours of work. This implies that the remaining time is free. There is a fundamental difference between telling a minor what they have to do some hours of the day - e.g. go to school - and telling them how they must apportion the entire rest of their time when they've finished their work. "Free time" loses meaning if it's all surveilled and controlled. Truckers don't have to be watched when they're not driving. Adults, too, have all their time free when not working, to waste or use productively as they please. To say you're limited to the remaining 19 hours of the day just means you have 19 hours of free time. It's no longer free time if the government begins to restrict it for reasons that are outside its remit.
Can you expand on what you think is not working well? From the couple of videos I tried, it worked extraordinarily well. Even though it's quite slow, the results are still very impressive.
Since it uses two catalysts and controls for heat production (and loss), it must be pretty efficient, more so than straightforward electrolysis.

It can be slower to produce the gasses, though. High efficiency, low throughput.
Lots of fodder in this article, but this one stood out to me:

"The school district originally purchased AnyVision after a mass shooting in 2018, with hopes that the technology would prevent another tragedy."

I'm curious how facial recognition would prevent a mass shooting. Is there some database of faceprints of known future mass shooters?
I tried to package something on debian many years ago before and gave up.

Apparently there were two sets of tools and I never could find good documentation on the “modern tools” or make sense of the docs for the older tools.

No, typical PWM is a repetitive hardware function of an embedded system, and operates at kHz or MHz. Industrial controls usually have a scan time or requested packet interval on the order of 10 ms, much to slow for PWM without dedicated peripherals. And even if you can transmit it, you still need to read it on the other side, again, high-speed IO is a dedicated thing, you won't buy step and direction outputs or encoder inputs for unused spares.

A PLC and a robot might interchange digital signals such as "In cycle", "Part present", "Faulted", "Clear of fixture", "Screw present", and "Cycle start". Hopefully the original designers also pulled a couple spare wires in case you need to add another sensor. But the old equipment is being asked to do something new, requirements now say you need to transmit, perhaps, which of dozens of part numbers to select from, or the touch point at which a sensor fired between 10 and 100mm. That's a binary signal with 6 or 7 bits, which means a $200 8-channel output card, multiconductor cable, and a $200 input card. When possible, you'd buy the fieldbus option cards from the factory and pull network cables. But in a pinch, with the more typical two spare inputs and two spare outputs, you can move some data to the time domain and work out "If aux1 is pulsed high for 680ms, the new sensor tripped at 68mm". One wire, one bit of state (0V or 24V), many values transmitted.

You could extend this concept with a clock signal, data signal, and transmit arbitrary serial data, but that's going a bit too far for most maintenance techs. A pair of timers is comprehensible.
I'm so glad to see this on the front page -- this website, in conjunction with a video from Two Minute Papers, is what convinced me to teach myself machine learning. I come from a filmmaking background, and have used green screen extensively. It's big, bulky, has to be set up correctly, lit correctly, and is expensive and just generally a pain to work with.

I'm currently working on a fully-automatic version of this based off some excellent research from the University of Washington. It's still in its infancy, but if you'd like to follow my progress, I post occasional updates over on https://nomoregreenscreen.com

This is just the beginning of what's possible in the intersection between DL and creative filmmaking, and I'm really excited to get to be in this field at a time when compute is cheaper than ever and all the information I could want is available for free on the internet!

I work in vision and I still have not heard a compelling case for Facial Recognition. There's useful things like iPhone unlock (similarly applied other places) and identification systems. But the potential for abuse is just far too high in my mind. They say don't give powers to Mr. Rodgers that you wouldn't want Hitler to inherit. This is one of those powers. The good is things we can still do easily with other systems. The bad is a 1984 dystopia (also see the recent HN article about Tencent[0]. Why is no one here concerned about cameras scanning children... That's just inappropriate pictures waiting to be leaked). Crime has been going down. Terrorism is extremely rare. Pareto exists.

Like the upside here is if Mr. Rogers is in power you can unlock your iPhone and (if everything works perfectly... good luck?) you can get on an airplane ~1 minutes faster. But if Hitler is in power you have modern Phrenology (which we're already seeing).

What am I missing here? What is the great use case that warrants this?

Making a PoC is usually only the beginning. Firmware upgrades for microcontrollers may be difficult to do in the field, without UART and JTAG debugging. If clients expect that pretty demos will continue working, they might be quite disappointed. It's better to follow good design patterns (Active Objects, state machines [1]) from the start when possible.

dmitrygr is a legendary embedded hacker [2]: his Transcend WiFi SD card reverse-engineering is what led to me having a PQI Air Card in my pocket, and he's also written a bit-banged Bluetooth Low Energy driver. Great for a demo or when there's nothing else available, but far from a finished product.

Writing a MISRA-compliant BLE driver would make me MISRA BLE.

Exactly. Hydrogen electrolysis is most efficient at elevated temperatures, and that was a problem in some exceptionally cold areas.

This is a development that makes electrolysis practical in those regions.
i believe this correlation is more accidental than planned.
i doubt that there is anyone who can claim to know exactly how much schooling in your native language is necessary before you can successfully pass a statistics class.

i believe the reverse is true. taking a statistics class will advance your language skills, because you learn a lot more by application than by theory. and there is no reason that these language skills need to be learned in isolation before you can apply them.

so maybe this slows down your learning for a bit, but even that is hardly provable because of different learning speeds of each student which likely vary far more than than the variation that language classes or the lack thereof would introduce.

actually, the whole concept of classes for your native language doesn't make sense in this context. learning your native language permeates everything. you learn language in every class, be it math, biology, sports or whatever. a dedicated native language class at best fills in gaps such as learning grammar, linguistics and literature. but it is not, and should not be a prerequisite to learning anything else.

the situation is a bit different when the language being used to teach is not your native language. a certain foundation in the language is necessary before you can follow classes, so a number of language classes are a prerequisite in that case

This is interesting to read now, because at the time (March 2020) I was watching Drs from Italy on YouTube saying that they recommended hi-flow O2 and proning with surgical masks on the patient. I remember this because I researched whether it would be worthwhile buying O2 cylinders or a generator, concluding : no, because it would be hard to produce the necessary flow with available equipment. Somehow this memo didn't make it out to the wider medical community it appears.
Chromium is a Google project, that they happen to open source.

That they put in a preference for their own interests wouldn't be 'malicious intent' from their part, it would be 'why they built it in the first place'.

That said, it may be anti-competitive.

If our array is sorted, the performance of the function should improve due to better branch prediction. But we’d be better of rewriting it as binary search in that case.

you aren't responding to someone proposing that cell phones cause cancer. they were refuting a weak argument that it is impossible, with an example of one kind of unanticipated interaction that could cause such an effect.

ie, saying that cell phone radiation doesn't cause cancer (or other negative effect) because the radiation is not ionizing, is a straw man- like saying that cigarettes cannot possibly cause cancer because the red glow of the cherry is also of sub-ionizing frequency.

Or you can be a Boglehead and in general not try to pick individual stocks and not try to time the market: https://www.bogleheads.org/wiki/Getting_started
"Bogleheads® emphasize regular saving, broad diversification, and sticking to one's investment plan regardless of market conditions. We follow a small number of simple investment principles that have been shown over time to produce risk-adjusted returns far greater than those achieved by the average investor. They have been further distilled and explained in thousands of posts on the forum. ..."

That said, sometimes people get lucky so YMMV. And the Boglehead philosophy and success (following by Jack Bogle, the creator of the first Index fund) has been forged primarily over the last few decades of US markets and people can question if anything substantial might change and when. Always lots of discussion about such things on that web board.

We kept a ledger on the fridge where we credited my allowance and debited my purchases on my mom’s credit card.

I didn’t have a smartphone but I could text. Around 14 I wrote a little Rails app that would receive transactions via SMS from Twilio. We never ended up using it but it was fun to write. Shortly after that I got a joint checking account with a debit card in my name.

Not surprised at all.
Austrian economists have been warning about this [1] since cronies, socialists and statists from central banks have started "stimulating" back in 2007.

> The wavelike movement affecting the economic system, the recurrence of periods of boom which are followed by periods of depression, is the unavoidable outcome of the attempts, repeated again and again, to lower the gross market rate of interest by means of credit expansion. There is no means of avoiding the final collapse of a boom brought about by credit expansion. The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved.

Bloomberg has always supported activist central banks. Now they're telling us there's no way out. Gee, what a surprise!

How the heck will anarchism help you when you don't have any power to implement the changes? You have to have the leverage to deny decision makers things they need or want or else you are simply subject to their whims, vote or no vote.

I've done professional video editing and VFX work. This will not get used among professionals. This machine learning tech is better than what's built into After Effects but that's irrelevant because the time it takes me to fix a mistake my software made is far smaller than the time it takes to learn new software that has a far smaller scope.

You're not going to beat Fusion, Nuke, or even consumer tools like Hitfilm at the VFX game. A better use of this tech would be to take the area you improved in and turn it into a plugin for all or one of these.
