Meta doesn't operate in China though, for not wanting to comply with their requirements of state-controlled censorship. I could see them applying similar reasoning here on principle (my god, I just used 'Meta' and 'principle' in the same sentence, I must be high). Another tech company might jump in that hole of course.

With regards to E2E, I wonder how it would work when you want to chat with someone outside Belgium though. If I'm the person outside Belgium, I wouldn't want E2E to be disabled just like that. And if WhatsApp can only be used between Belgians, that's quite a hinderance.

Belgium doesn't care about Meta revenue and rightly so, but if a law would be the reason that Meta pulls the plug on Belgium, that seems like a cause for a possible serious political backlash.
As long as Android has a Linux kernel running in the background there will be filesystem access. If Google ends up switching to Fuchsia this might change but we're not there yet. General purpose tools seem to run just fine on Android for the most without the need for much porting as can be seen by glancing through the list of patches [1] needed to build a host of packages for Termux.

Interesting approach, but if it's decentralized, can I fully self-host? I feel like this term doesn't really apply when you have a centralized provider.

If you have a solution we should be trusting, I would avoid "buzzword bingo" and just be straightforward with your customers.
I’ve clarified in my comment that it is clear to me.
> watching the video [...] it is not clear if a human would have done any better.

Anyone who's ever taken a photograph in low light conditions knows that in the dark, cameras fail to capture loads of detail that humans can make out just fine.

I'd wager a human driving in such circumstances would have seen the truck much more easily than we can see it in some dark, blurry dashcam footage.
Your original comment was speaking very broadly and not about this specific accident. I responded broadly and not about the specific accident. Your response was only about this accident and ignored my broader point.

Yes, this accident is a problem that Tesla needs to work to fix. But no system is going to ever be flawless and I would bet many humans and other manufacturer emergency braking systems would fail to avoid this accident.

In the meantime everyone, from Tesla fanboys to Tesla critics, should be mindful about how they talk about these things because confusion is dangerous regardless of its source.

I think the last episode of The Rookie has a scene where a lady is trying to talk to one of the main characters while they're trying to wrangle a daylight drunk individual. The lady intervenes and gets the drunk to sit quietly on the curb.

Then announces, "I teach fourth graders," by way of explaining how that worked.
Every problem is probably hyperbole. It will solve lots of problems. But it feels a bit naive to expect it to solve all problems. We've got so much more technology than say, ancient Greece ever imagined, but we still have problems.

Latency is exactly why I'd prefer a last-gen radio with open-source drivers. An 802.11ac router with the latest open-source drivers (ath10k and mt76) will give you better real-world latency, because there are open-source developers working to optimize for the metrics that actually improve real-world user experiences rather than seeking the largest achievable throughput numbers on naive speed tests.

802.11ax on its own does nothing to address the problem of wasting too much airtime serving a client at the extreme edge of your AP's range where neither 802.11ax or ac transmission rates will work. That kind of problem must be tackled with better QoS strategies that are not inherently tied to any particular generation of the WiFi standards, but in practice can only be developed and tested for chipsets that are sufficiently hackable
If covid really is the greatest threat to our society like the media leads us to believe, covid testing and vaccine passports can't be on the honor system or easily faked. We need a new government agency like the "Public Health Compliance Administration" (similar to the DEA or TSA) to enforce the compliance. Non-compliance would result in huge fines or felonies. PHCA officers would have the authority to raid houses suspected of hosting super-spreader events (birthday parties, thanksgiving dinners, etc.) and or stop and test random people in restaurants, arresting those who are unvaccinated with a fake passport.

Sounds crazy, but we are on the path to increasingly authoritarian covid compliance. Other countries are even further along that path.

I personally think covid is no longer an emergency with the advent of vaccines. I say leave it up to the individual whether to get vaccinated or not, and implement bed rationing for the unvaccinated if ICUs are over capacity. Otherwise there is no endgame, we will wring our hands and live in fear until the end of time.

> All radar based braking systems in the market filter out stationary objects because too many false positives.

Absolutely categorically NOT true.

It may not fit your narrative but Front Radar electronics/firmware filter out stationary object ONLY if they are outside the vehicle trajectory envelope.

The majority of false positives are due to overhead passthroughs which may fall within the envelope, if the radar calibration is insufficient.

EuroNCAP tests for AEB include both moving targets AND stationary targets. [0]

Even those low-cost Bosch front Radar assemblies in entry-level vehicles could have mitigated that impact.

IMHO everyone interested in computer science should try some Borges, at least Ficciones. Many of his stories are so mind-boggingly close to many topics of interest in CS. Beside The Library of Babel, I can come up with at least two other examples:

* Tlon Uqbar Orbis Tertius describes an extreme Idealistic philosophy where things exist only as long as someone (something?) perceives them, which IMHO is an apt description of the digital world.

* Funes describes the life of a man with perfect recall: so perfect, in fact, that he is unable to classify things (e.g., stones, or dogs) due to the infinite amount of details that set every single object apart from every other. And in a way, don't ML algorithms work by teaching a computer to forget about these details?

It was an oral tradition. Recitation was how it was passed on before it was finally written down. You see the echoes of this in a lot of early Greek writing, they contain a large amount of quotes out of Homer. Being able to navigate this maze of "Darmok and Jalad"-speak with Homer quotes meant you were well educated.

Only thing I've found that comes close is some of Augustine's writing. He does the same with Bible quotes in his Confessions.
Entirely depends on who you ask and in what situation I'm sure. Most of my opinions are based on the world being too complicated for anyone to make optimal decisions regarding safety/finance/etc.

Which is Tesla crashing into stopped trucks in the middle of the road. The fact is, we have a pattern here, and it is now documented.

As sad as it is, this Twitter-thread isn't "news". The NHTSA opened an investigation last year, but you know how slowly the government works. Everyone has known this.

There is a pattern here about Tesla's emergency braking, be it on the default package, the 2015-era Autopilot for $5000, or the modern 2021-era Autopilot for $10,000.

The emergency braking simply doesn't work (https://www.carscoops.com/2020/09/tesla-model-3-fails-an-aut...).
> I always seem to find an excuse as to why it's not worth continuing, right before actually accomplishing anything with the tool/skill in question. ... As such, I spend many days feeling like the donkey in front of the stack of hay and the pail of water.

I can really relate to that. It's necessary to choose something that is not too far out of the comfort zone. Like choosing something novel is good but the majority of the libraries/tools should not be new. That's key to be able to both start and continue a long time. I'd make sure the first proof-of-concept can be done within a month, afterwards I'd either stop the project or continue. Otherwise it's just too frustrating.

Afterwards you can still build stuff on top. If the problem is open ended but has a reachable first plateau that provides a basic use case this can be a nice "rabbit hole project" that you can spend an infinite amount of time on if that's what you're looking for.
Pharma/biotech is particularly big but look at a magazine like Tech Review and there's a lot of diversity.

In addition to the weather (which really isn't that bad), part of it is I think that a lot of people with SV companies tend to think of tech as "what SV companies do" which naturally leads to them seeing less "tech" in other places. (Though there are sizable outposts of quite a few West coast employers at this point in addition to the home-grown ones.

Tech actually in the city was almost non-existent for a long time. Hence the Route 128 computer companies. But that's shifted a fair bit again over the past 20 years.

The tesla safety story should be whole system.

My question - how did the driver do in this crash?

This isn't super clear cut, the vehicle was unlit in fast lane on the freeway. That could be a tough for a number of drivers.

That said, one lidar sensor maybe? Just to let at least brakes come on?
ADAS must use qualified chips and that one was a pretty standard one some years ago. I like others better, but you must see them in system context and be able to continuously process that stream. Given the power budget and other constraints this was what a number of manufacturers ended up with. After all these guys are not dumb, they just need to desing in many more aspects than mobile phones.

Your example is an example of choice or consent. They also had the option to burn their hand written books and scrolls down periodically. Systems like IA take that choice away.
Agreed. Being able to drop seamlessly into an imperative style is very useful.

I’m someone who isn’t an experienced functional programmer, or that deeply knowledgeable about type systems and category theory etc, but OCaml is still approachable to me, I feel I can get stuff done in it. I didn’t feel that way with Haskell - I tried, but found the number of ways to do things overwhelming, and a lot of it felt very theoretical. Of course, Haskell’s pureness is an impressive and interesting feature; but it isn’t for me.

OCaml also has much better systems programming abilities compared with Haskell, IMO. It feels like OCaml is the Rust of the functional programming world (and this is no accident, the Rust compiler was first implemented in OCaml in fact).

This is all completely subjective of course.

This happened to me too.

Small company, very fast paced, learned new tech very quickly for two years and actually pumped out awesome products (in addition to other small company perks).

After the acquisition, the way we worked completely changed for the worse. I ended up leaving and so did about 50% of the developers.

Promotions became much more difficult to achieve, raises were below or only matched inflation, and pretty much every aspect of work became more bureaucratic. This was exactly why I had left my previous company, and I ended up leaving this one as well after giving it a shot. Stagnating my career was not worth it especially in a hot job market.
You don't require a bank in the same sense that you don't require a baker. If you want to make your own bread, go head, nobody is stopping you. But in a modern society people engage in division of labour and specialisation, because this allows us to be orders of magnitude more productive and have things that we couldn't dream of making ourselves. People don't want to make their own bread, and they don't want to be their own bank either.
Maybe humans should become more accommodating of past mistakes.
Great points gtsop! We have a very similar understanding of decentralization.
My co-founder and I are passionately working on making sure that we eventually reach that goal where Slik keep going, even if any one actor falls down.

Here were our goals when we started this out -

- Prove and implement the encryption technology [completed],

- Switch over from centralized storage to decentralized storage [completed],

The above two goals help us achieve a working solution that users can start adopting.

Next few near-term goals are -

- Switch over from centralized compute to decentralized compute,

- Make the code open-source so that the technology can be extended, forked, etc as the community needs.

Hope that gives you a reason to be stoked! :)
Perhaps have a look at Arweave (https://www.arweave.org).
Thanks for posting! Having watched this version there's no way any human driver paying attention would hit that truck. It would have been more visible in actuality as the dynamic range of video doesn't compare to eyesight.
However, the car was equipped with radar. Twitter author also said that the truck was seen by radar. I don't see how something like this could have been missed by a radar-equipped car. I chalk it up to the black-box nature of these models and the general lack of awareness about what bizarre edge cases could be encoded in the model's parameters.
I'm reminded of the time the Uber SDC hit the pedestrian. Uber initally released one camera's footage, where the ped wasn't visible until it was too late.[1] But then others drove the same path in the same lighting conditions and, even with their (unspecialized) dashcams it was clear you had plenty of time to see someone in the street -- and even that much is ignoring how humans see better at night than the dashcam would!

(Oddly, I can't seem to find any such videos at the moment or know what terms I should be using to search, but I definitely remember people uploading such videos to YouTube.)

My own interpretation of the definition of decentralized as it pertains to technology would also imply there is not a single super-node you have to boot-strap from. One should be able to host their own boot-strapping cluster of nodes so that if a company goes out of business their nodes will continue to work, software updates not withstanding.

Not depending on a single node to me sounds more like distributed like Tor or clustered like Ceph or in some cases federated like Mastadon or Matrix.

Do you know if there's a database of natural chemicals for filters?

Specifically, I'm looking for a 0.3 µm ultraviolet filter (or any base-2 harmonic e.g. 2 * 0.3 = 0.6µm, 4x, 8x, 16x).

Tangentially related, I'm also searching for any flowers whose pollen grains are 19.2 µm (0.3 µm * 64).

As you say, the 19th-century (and Ancient Greek, Chinese, Egyptian, IVC) experts knew well about the biological solutions for technical questions. I just have no idea where to learn about natural substances.

Couldn’t an infrared camera have helped? black paint is not anyways black in infrared, and the recently-crashed car would likely have a heat signature. I wonder if they would have to start from scratch with their training data, or if black and white could be used for everything.
This works as long as those characters truly are a rarity and will probably become unbearable otherwise. For example, try opening some Agda code, or reading firmware or BSP code with Chinese comments (hello, ST Microelectronics), or some other ancient or internal code with non-Latin native-language comments (Japanese is pretty common, my native Russian can also be found in the wild occasionally).

I’ve heard somewhere that Java’s support for Unicode identifiers was originally motivated not only by “oh shiny” (although I expect there’s a measure of that, too), but also by allowing the Japanese to write their code how they wanted it, and apparently did indeed help with capturing mindshare. Though, to be fair, I’ve never actually seen Java code with Japanese identifiers.
I am unable to verify your claim. What I've seen is that Japan has about the same rate of overweight, obesity, morbid obesity and type 2 diabetes. Is it possible that you compared a figure that combines multiple categories to a figure that just looks at a single figure? For example combining type 1 and type 2 diabetes would be misleading, as type 1 diabetes is caused by fundamentally different factors than type 2 diabetes. Also did you ensure that you are comparing data for the same or similar year?
I am neither going to defend the feature's name or get into a debate about it. I am simply pointing out that the confusion does not have one single source like you originally implied.
I believe a good piece of software is like any well made tool. It fulfills a single purpose, elegantly and simply. It is closed for further modification, but open for easy extension.

It would be a very long post to go through it all, but suffice it to say it incentivizes other people to maintain the peg through bribing them with potential rewards. There is no person at MakerDAO printing new DAI like would occur with tether. The system prints and destroys DAI based on individual users acting selfishly seeking profit. The people using the system keep the peg non-altruistically. It's really quite a clever idea.
The terms are not well understood. Allow me to over simplify this into 3 buckets:

* centralized - a single funnel by which all traffic is managed, such as a web server

* federated - various disparate nodes comprising a centrally managed/governed network. This is blockchain and IPFS where the network is an application layer protocol. The more appropriate description is pseudo-decentralized or semi-autonomous. It is not centralized but it is also not fully decentralized.

* decentralized - disparate nodes communicating directly using agreed upon conventions. There is no centrally managed network. Think in terms of snail mail, IPv6, or phone numbers. This could be as simple as people using an agreed upon application to abstract away the transmission concerns but that application does not route traffic through a third party server.

The greatest misconception, or rather abuse of the term decentralized, I am seeing on HN is confusing it with a federated scheme. Federated schemes are not decentralized. Web3 is not decentralized. They are distributed.

In some cases the abuse of these terms is accidental, but it seems in many cases it is intentional. I suspect some large organizations, yes I am looking at you Facebook and Andreesen-Horowitz, are fearing functional obsolescence, either in their investments or their properties, in the near future and so are attempting to validate their existence by muddying the waters. By functional obsolescence I mean what would you need Facebook for if you can directly transmit media, or micropayments, between friends and family without some sinister third party destroying your privacy. The commercial web has become very hostile to its users, so pending a proper convenient end-user application, there is little incentive to continue using the web.
No, this is FUD.

Most people will only open one channel ever in their lifetime.

Your scenario is correct only if you will only send, most people won't, most people will first receive (get paid) then send.

Say someone wants in, he opens a $20 channel, maybe he wants to pay for some small stuf at first so $20 will do.

But then this person will get paid for his work, say $1k.. his channel isn't constrained to those first $20, this channel is now "widened" to $1k.
