Blockchain is just a ledger. So "the Blockchain" does not make anything significantly better. Its in fact ridiculously expensive.

The idea is that everytime sweat shop X finishes sewing sequins on a dress, they can scan the RFID tag on the dress with their smartphone, and the ledger gets updated, and then Walmart can prepare for that dress, the shipping company can print out labels etc.

Its a good idea.

Industries are supposed to work this out, create their own cheaper blockchains that just need some sort of simple KYC to get started, then its as cheap as email to add your little bit to the supply chain.

I dont know of any successful implementations

Edit: no blockchain will solve the grey market problems. Everything will have to be made genuninely on the chain. Which starts to lead to probelsm with if you cannot get permission to write to the chain ... etc etc
That has the same basic idea as the mustache version, but is pithier. I still prefer the surrealism of the bicycle.

Yup, Java is common among low-latency-ish market makers like Goldman Sachs, UBS, HSBC, Morgan Stanley and others.

Edit: since I'm being down-voted for this comment - I worked in all the above banks on low-latency Java projects. That you don't like the language/runtime doesn't change the facts.

Umm...we sorta do.

As a neuroscience postdoc, I have done virtually everything from analysis to zookeeping, including some (light) fabrication. We outsource really difficult or mass-production stuff to pro, and there's a single, very overworked machinist who can sometimes help you, but most of the time it's DIY.
Tree-sitter is unfathomable to me. This is the grammar for Ruby:

https://github.com/tree-sitter/tree-sitter-ruby/blob/master/...

I find it absolutely amazing that a grammar for something as complicated as Ruby can be so concise. Less than a thousand lines. The corresponding Bison grammar is 13k lines. And I think the tree-sitter one is scannerless so also includes the lexer?! How do they do it?
Agreed. I would wager that in any sport where technique is important/difficult (swimming, nordic skiing, and to a lesser extent running), efficiency will improve over time, even for elite athletes.
> The crypto killer app is using the money to buy illegal drugs.

Meeh! Not even that, anymore.

In Brazil there was a brief moment in 2014 when you could buy marijuana and cocaine with bitcoins. But now, with all this volatility, transfer costs and low liquidity, not even drug dealers want crypto currency.
> For some reason I thought CoC just didn’t allow programs that lack a termination proof. Oops.

I'm not sure about CoC-the-abstract-calculus-on-paper, but I guess it cannot allow programs that lack a termination proof. Coq-the-concrete-implementation-of-CoC does allow some. Or not, depending how you look at it: What it will really do is infer a termination proof behind the scenes for certain simple cases, like iterating over a list and the recursive call always being on the tail of the current list. So everything has a termination proof in Coq, it's just that in simple cases you get it for free.

The crux of it is that suicide rejects the gift of life

"Everyone is responsible for his life before God who has given it to him. It is God who remains the sovereign Master of life. We are obliged to accept life gratefully and preserve it for his honor and the salvation of our souls. We are stewards, not owners, of the life God has entrusted to us. It is not ours to dispose of."

Agree. David Bowie once demonstrated it to a reporter. They walked together through Manhattan. No one bothered them. Bowie then said he was going to “turn it on”. Something in his expression slightly changed. And then he was mobbed by fans.
I feel like the artists/celebrities/directors who publicly announce that they're quitting usually end up coming back in a few years... Director Miyazaki comes to mind in more recent years.

Those that actually "quit" just quietly drift away out of the public scene.
The video game SOMA touches on a similar topic of brain scans, "copying" your brain somewhere else (while leaving the old one still around) and general humanity-ness.

Common mineral could be key to tackling climate change
At least now. Back during the golden age of desktop from 2000 to about 2010 things were stable. But then dev funding for linux and it's primary libs went back to be about creating the most bleeding edge, fastest, possible environment for running server farms for mega-corps and desktop stability was abandoned.

The end result is the fever that is containerization as a symptom of the sickness that is future shock from devs always using the latest.

Fibery is like the penultimate example of not starting with a niche, which makes this article quite funny. They are the anti-niche, and further, defining a niche as focusing on a specific size of company is also an inversion of what most would call a niche...

They had a unique opportunity here to write an article “don’t start with a niche”, but I don’t know if they have the success yet to prove it.
What you're describing is mostly a failure of US commingled recycling system. Meanwhile most of EU countries successfully recycle about 90% of collected glass, collected in glass-only containers.

Making new glass can be an issue, as it typically uses sand, which is not very renewable and sand mining in many countries causes massive issues with flooding, droughts, sinking, black markets, even sand mafia!

No we should not landfill everything after a single use, or we will soon run out of reasonably accessible raw materials in suitable forms.
Two learings on my side:

1. Promises are handled in micro-tasks.

Show HN: I made a reader for HN with Angular
Hello everyone, this is the first time I share a project publicly. It's yet another reader for HN, not the best out there but helped me to learn Angular better.

>> Under a few hundred feet, radiation will probably drop off enough to not cause damage.

At a few hundred feet, a structure able to hold off the water pressure would probably be thick enough to hold off the radiation if installed on the surface. In rough numbers, the mass of air above us now is equivalent to about 10m depth of seawater. A few hundred feet, call it 100m, would be like having ten atmospheres worth of radiation absorption above us. We need not go that far. Relatively thin engineered coatings on glass/plastic sheets would be as effective at blocking the extra UV.
> The end result is the same, you can’t use the hardware after the time period is up, but for some reason the admin feels much more comfortable about it.

Simple: predictability. With a subscription based model, admin has to deal with recurring (monthly / yearly) payments, and the possibility is always there that whatever SaaS you choose it gets bought up and discontinued. Something you own and host yourself, even if it gets useless after three years, does not incur any administrative overhead and there is no risk of the provider vanishing. Also, there are no "surprise auto renewals" or random price hikes.

> 2. It’s hard get funding to hire someone to set up a service to transfer large amounts of data from different places.

Never underestimate the bandwidth of a 40 ton truck filled with SD cards. Joke aside: especially off-campus buildings have ... less than optimal Internet / fibre connections and those that do exist are often enough at enough load to make it unwise to shuffle large amounts of data through them without disrupting ongoing operations.
Hm. How does this work? Isn't the lawyers (and/or notaries) supposed to establish that the person making the will understands its content? How does suicide/euthanasia factor into this at all? If the aging/ailing person feels pressured by their descendants, how does living longer would help them? If they are capable of making/expressing their will aren't they capable of not taking euthanasia? On the other hand if they are incapable of signing a will they are also incapable of requesting euthanasia, right?

And even if we simply leave the will part out of this, if they are pressured by "loved ones" to end it with dignity, and they agree, who are we to disagree? If they don't agree then it's a crime to harass someone to death (whatever the method).

What am I missing? Could you explain your father's argument? Thanks!
It is another classic confusion between a definition in technical jargon (maybe even a formal definition) and the vernacular. Real-time for most people means "instantaneous," and definitions of latency are not considered. So it is a shorthand for "low-latency" without a rooted understanding latency at all.
> But you definitely don't get O(5 uSec) performance out of the box.

Tick-to-trade? The first version of our trading system in Java, had this level of performance in the first version.

> If you hit a GC pause or have to do heap allocation

We ended up running the code through profiler on our CI system which would fail the build if it detected any potential paths of GC. Object pools and flyweights everywhere.
AFAIK there is not a standardized way to do this but there's no reason it can't -- you are free to define your own Content-Type or use framed binary, or whatever else. If you already have schemas on either side (or code to do dynamic discovery), and a way to pack/unpack you can send different kinds of data across.

This is less ideal than GraphQL in this case, since GraphQL has done this hard work and standardized it/created the conforming reference clients/servers already.
It depends on how you define fairly close. Iqaluit Airport is just over 1,800 miles from the North Pole, or about four hours of flying time (at cruising speed, more if you have to fly lower with a dead engine).
I 100% agree with your statement. I also realize you are not
championing HATEOAS here necessarily.

That said, I am curious if you have found this "linking" aspect of HATEOAS useful for actual implementations? I have been doing integration work with a system that strictly adheres to "REST level 3" and "HATEOAS" principles for the past few years, and I myself have found the "explore-ability" of the API super handy. That said, the self-documenting nature only goes so far, and in the end I'm not sure the internal linking stuff is preferable to robust documentation.

I'm not trying to be down on this necessarily, I actually generally push back on the adoption of GraphQL as the answer to every problem.
> No user cares whether an error response came back with a 400 or a 409 status

Unless your product is itself an API, your users shouldn't be exposed to its status codes. Sorry for dispensing trite advice, but you should really have a nice client between API and users, that can translate the difference between 400 and 409 statuses in a comprehensible and friendly way. :)
I think the capacity factor of nuclear is much closer to 95% or higher these days, but call it 100% for simplicity

PV capacity factor is typically 16%-28% [1], which adjusting the W/kg, gives us:

Solar PV: 0.8W/kg - 2.8W/kg, capacity factor adjusted (with supporting infrastructure weighing 2x the panels, a total spitball)

Nuclear: 0.8W/kg - 4.5W/kg, capacity factor adjusted, two different modern reactor designs, concrete only.

With this ratio, higher numbers mean better power densities, and the ranges completely overlap between nuclear and solar PV. Nuclear isn't achieving orders of magnitude better power density over solar.

Small typo-ish error in the article, emphasis mine:

Surely that should say that the user isn't not unauthorised?
It still is as there's plenty of non-low-latency related stuff that you still need from the ecosystem such as portability, dependency management, common libraries and utilities, debuggers, profilers, etc.
I mean it "works", but so do steam powered cars. The problem is most people don't actually use it, just trade it. The space used to mostly involve people who actually wanted to decentralize currencies, now it's almost exclusively "hodl $$$$$ to the moon etc". This article is articulating what's been clear to many people who really believed in the promise of decentralized currency: crypto in its current iteration has essentially failed. Time to try something else.
An Overview of BBS Programs
> A caveat: The cycling in the new study was performed on stationary bikes at a predetermined cadence. It’s possible that the benefits of experience and bike-specific training would be more noticeable on the open road at a freely chosen cadence.

A pretty big caveat. I’m not surprised that cycling on a stationary bike at a fixed cadence has very little room for skill/technique improvements. This invalidates the results vis. real cycling in my book. Gear selection, out-of-saddle technique, etc. Though having said that I’d expect the skill-based component to be much smaller in riding than running as the movement pattern is much more constrained.

Still an interesting result, since it does show that there is a skill-based efficiency gain in running.
Maybe. But most airline companies can ground a small portion of their fleet and it not really affect their outcome. They should have some redundancy built into their maintenance schedules so that 60 planes, even in a single company shouldnt have too much of a flight schedule burden.
Nope. As long as Tether keeps paying $1 for each Tether it's them keeping the price at $1, not human psychology. Maybe they don't have enough dollars for all Tethers, but your experiment won't uncover that.

I'm not saying that Google's ML isn't doing some very fancy things but:

- Ultimately, any supervised technique will depend on some system that can provide ground truth, which in these applications must be from humans. You can't avoid some humans in the loop and still learn a fuzzy human concept like "is hate speech". But if your aren't gathering that ground truth info in a very deliberate way, you can end up with a range of gaps or artifacts.

- There's a broad swath of technical approaches which would consider multiple kinds of information, but ensemble them together such that a very strong signal from one can have a determinative impact. It would be easy to have a situation where if the video itself talks about white/black and attack/threat/defend many times, the score from some language model into a top level ensemble model is very high and the other components may not matter.

- But a lot of those other components may often be in agreement because of natural structure. A video says black/white a lot, several other videos on the channel do the same, and a bunch of interested users also look at other channels that have very similar feature vectors, suddenly a content level, channel level and community level signal are all in agreement, and your model can believe it found a subcommunity of hate speech.

Incorporating many kinds of info into an ML model isn't that hard ... But doing so in a way which is tightly integrated (eg I'm likely to use a specific meaning of a term in my video which matches a use in a video of a related channel linked in my video description, and that use of that word is also related to what's visible in the video at around that time) is pretty hard. Doing so in a way which distinguishes predictions from confidences is harder.

All of which is just to say that it's hard to build a really good black box for a complex problem, especially one based around subjective human concepts, and maybe both we and the black boxes would do better by attaching more uncertainty to their predictions.

If it's worth the channel owner spending many hours making videos, and viewers spending many many more watching them, I think it's not crazy to ask that if the model predicts that it's likely disallowed content, that a manual reviewer can take a quick look.
macOS is at least 20 years old, and Apple needs to maintain it indefinitely. They need engineers who aren't going to accidentally break things for the 100 million strong existing user base. Nobody rapidly specializes in Mac development, there is simply no substitute for experience in this area.

The results are pretty obvious and depressing when you see Apple throw engineers at the Mac who don't understand the Mac. Low quality, bugs, constant accidental breakage, bad design in opposition to the platform standards.

Not every engineer can work on "the next great thing". You need a lot of engineers to work on the old great thing too. A mixture, a balance of engineers is important. A company gets diminishing returns from having all jack-of-all-trades engineers.

Google is the absolute worst at this. They're constantly creating new things... and then discontinuing them a few years later. Their follow through is terrible. Nobody wants to do long-term maintenance. Even though most of Google's revenue comes from the old things, such as search. (My impression that Google search is actually less accurate and useful now than it was 10 years ago.)

People love to make sports analogies, so here's mine: imagine a football team that put 11 all-star quarterbacks on the field. They would be the worst football team in the world. Every team needs role players.
The economic damage is being done by the pandemic: people aren’t going to congregate when it’s risky and many businesses can’t survive without high in-person volume. Having lockdowns can get you back to the point where businesses can safely operate with community spread control measures (see e.g. Australia or Taiwan).

What won’t work is attacking medical precautions or dissembling about vaccine effectiveness — and on that latter point, if you are really worried about variants the best way to stop them is carefully following medical advice to prevent community spread because each person who gets infected is something on the order of 10e9 chances for a new mutation which is more competitive. If people had worn masks and locked down a year ago this wouldn’t be anywhere near as bad a situation.

Whilst agreeing that much of the discussion of WW2 in the UK is unhealthy - especially in the tabloid press etc - not sure that the "ignorance of some of the things that Britain did " is valid. There has been and continues to be wide awareness of tactics like 'area bombing' and their consequences.

The biggest criticism I think is that there is too much discussion of the war and that it overstates the UK's role.

Yeah, that was my feeling about Bitcoin a few years ago after dabbling in it and then getting out (to the tune of 1.25 million... which of course would be much greater now, had I held any... sigh)

I originally got into it for the technical aspects of mining being interesting. Then all the speculators came in, then I realized that (perhaps due to my Psych major) I was pretty good at predicting local price maxima, but then after a time that felt too much like stealing from the dumber, which is not a vibe that brings happiness to me, so I got out of it. I'd rather use my intelligence to produce value by coding.
