It's a shame because setting up some microphones around the city to detect a firearm discharge seems like a great idea.

It's an idea, yes, but a *great* idea? There are so many technical, social and civil rights issues wrapped up in this idea on its face, I think its performance history should be part of whether it gets to enjoy the label of being a "great idea."

Since it misclassifies noises, isn't exactly sure of the origin, and can read echos as additional shots, is it useless?

Furthermore, since it can and does record human voices speaking, and creates permanent records into the private hands of a for-profit company that is allowed to sell that data to 3rd parties, does it actually cross a line from being useless to being harmful? It might.
I don't think that reducing CO2 emissions from a given electrical plant should be assumed to be something that made the plant more efficient and the electricity it produces to be cheaper, and therefore resulting in a proportionate increase in consumption.

In my opinion, this is a false dichotomy.
It didn't.

It maybe slowed down decommission of existing power plants, but nobody would build a coal power plant today from scratch in the west. These things last for a generation, while an administration 8 years at most.
You can still write microcode! You just have to design the whole processor yourself.

I've recently been studying AM2900 (bit-slice) processor design. There are still people out there putting microcoded systems together on FPGAs!

I am investigating it, because I think there might be some useful design aspects that could be re-used, but mostly out of retro computing interest :)
It is weird that they went with a brand new company to provide the lift for their NSO launches. Especially when they haven't executed on a heavy lift engine yet. It feels like New Glenn especially is a pipe dream.

> "I love Windows" does not refute anything. It's just tribalism.

Let me sum up:

>> There's no good reason to use Windows

> If Windows fits how you use a computer better, then that is a good reason.

That's it, that's all I'm saying. I didn't even say Windows was good. I certainly didn't say I love Windows, because I really don't and you will find many posts by me to back that up.

> Bystanders read that and decide for themselves.

THIS thinking precisely illustrates why I didn't elaborate on why I use Windows. With evangelists it isn't about discussion, or understanding, it's about performing a fucking sales pitch and I'm goddamned sick of it.
Those are all much better options than a Ponzi scheme/ financial bubble.

> Time to add tariffs on goods produced by states who made the decision of going all-in on polluting power generation, and potentially apply immigration quotas to citizens of these countries.

Sure, let's have a tariff on goods made in a country, that scales proportionately to the per-capita CO2 emissions in it.

The United States would be one of the most heavily tariffed countries in the world, if we go down that road. China would be... Middle of the pack.
It's not even the commute from my perspective.

It's having to live in places like New York City. It's not worth it anymore. Real estate ownership is priced out of reach as is a comfortable quality of life that can weather medium-term economic uncertainties.
This is really interesting to me. Back when I was a kid, I did a lot of programming for fun. I made small computer games, cracking and all sort of fun things.

Nowadays that I do it as my main job, it is nut as fun. Once you have to learn yet another framework or technology, it becomes "a chore" (that I am paid to do.)

I also play chess as a very light hobby. I am only ~1750 at Lichess and would be happy to be better, but apparently I am at the point that to improve I would have to dedicate a lot of time to read books and memorize openings/middle games etc. I decided not to do it because I would not enjoy it at that point.
I’m not sure what you’re talking about.

I own a Tesla Model 3 as my daily driver. Phantom breaking works exactly the way I described it. And it’s not hard to understand why: the intent of the system (like all other emergency braking systems on modern cars) is to avoid a collision with a perceived object in front of the car. A gentle regenerative slowdown wouldn’t even make sense in that scenario.

Phantom breaking behaves the way a human driver would if they were attempting to stop short of an impending front collision. It just so happens that the Tesla is happy to engage that behavior in all kinds of fun scenarios, like if somebody leans an inch into your lane, or a bridge has a shadow it doesn’t like, or it decides the potholes are a force field in front of your car.
> I would never buy a Tesla because I see better options in the EV space,

Only Tesla EVs have range over 300miles EPA and cost less than 50k.
Tesla is not as good as you might think. It has huge following, and I respect what they are trying to do, but the way they treat people is abominable:

- they go fast and in process neglect safety. My personal friend had been stuck on the intersection because his model 3 started automatically updating system software
- they actively block any third party repair shops from fixing cars that broke outside warranty period without providing alternative. Specific case was when they quoted a guy $16K when a small part underneath car was broken off. Third party repaired it for $700.
- they censor critics. Namely, they disable Rich Rebuilds's account with $200,000 worth of referral bonuses

I would go with Toyota instead of Tesla anytime. In fact I did go with RAV4 Prime as my vehicle of choice. Toyota's stance on fully battery powered car makes absolute sense. We need more conservative policies on electric vehicles, where consumer is protected
For a more interesting critique check out this podcast titled “Bitcoin is right-wing technology” https://overcast.fm/+ZpQA7ciS0
That's true, but it seems to be an issue with Tesla as a company rather than electric vehicles as a product.
Most people don't realize this. Even Panasonic, which is the most experienced and produce most of the Li-ion batteries today is still struggling to expand their GWh capacity.
Support for an architecture would be a minor release, no? That's "adding a feature". It wouldn't be a breaking change.
Your data only goes to 2016. In just 4-5 years, the UK’s per capita emissions have continued to fall (thanks to retiring coal very quickly!) while China’s has risen to above that of the OECD average for the first time: https://rhg.com/research/chinas-emissions-surpass-developed-...
Could this be patching the Pegasus exploit?
Good job, you found how the real world works. I'm sure there's no code from any other language with vulnerabilities in it posted online.
If you assume that your sampling is random, it's actually not too hard.

If you were able to pick randomly from all over the planet and ask who was male and who was female, you'd probably get a number of around 50-50 with a sample size of just 10. Maybe it's 60-40 or 40-60, but it's unlikely to be all of one or all of the other. That would happen about 1 time in a thousand.

If you asked a thousand people there's basically zero chance you'd get all of one or the other. Your low number might be 490 or even 480, but it would take a bizarre coincidence if it were even as low as 450.

The big "if" is assuming that you can sample randomly. That's the hard part. There are a ton of ways they go about trying to ensure that they're doing a random sample, but yeah, you do have to take it with a grain of salt.

But setting that aside, the fact that they sample only a tiny percentage isn't really a problem. The exponential nature of coincidences makes significant departures from reality unlikely. One coincidence is rare; hundreds is basically impossible.

Most of the math behind statistics assumes that there are infinite populations of people. It requires special corrections if you're dealing with only small groups like hundreds. Once you get into the millions, it might as well be infinite. And as long as your sampling is random, it still works out to give reasonably close answers.
I live in a city, and though I have a dedicated space, I cannot independently choose to put in EV charging infrastructure, so I also don't know how this will work out in my current place.

But I'm more thinking like ... Texas had its giant power outage. California sometimes has rolling blackouts. If a large proportion of vehicles were electric, the current system couldn't handle it, right? And if a large power outage in turn has follow-on effects on transportation where it's suddenly harder for goods or people to leave, that seems even worse.

So I hope _someone_ has a plan for how the power grid and energy storage and charging infrastructure all need to grow and become more robust at the right pace, in parallel with EV adoption. And that plan, I hope, includes projections on both EV adoption and charging infra availability and power grid capacity and resilience?
Ah yes, good point about corn. That's heavily subsidized and will only become more so since every politician wants to win Iowa early in the primary
> Also, there is nothing which proves that Tether actually isn't backed by anything.

There is a lot of circumstantial evidence though. To wit:

* Tether was previously caught lying, in a manner that is attuned to how many big frauds start (you hit a small road bump, so you lie to cover up the road bump, figuring you'll be able to make up the shortfall before too long. But now your lying projections are going faster than your ability to catch up, so what was originally a "small" lie is now a "big" lie). Tether had had the cash, until it was stolen from them, and they started lying to pretend that it wasn't stolen.

* Notably, Tether has yet to provide any audited statement of their claimed finances, in over 4 years. Even the attestations that they have come out with don't actually provide much in the way of reassurance.

* Their claimed asset breakdown, the closest thing any of us have to being able to being able to validate their claims, is presented in the form of 2 pie charts with vague labels, one of which is so bad that no one knows what it's supposed to mean ("reverse repo notes").

* Doing the math in the above point, they claim to be one of the largest consumers of commercial paper. They haven't said whose commercial paper they're buying, and no one has reported transacting with them. Supposedly this is for privacy, but it is the standard in the entire industry to just list all of your holdings for transparency's sake [1].

* Also, Tether has increased its issuance to the tune of several billion dollars a month. That's the kind of extraordinary claim that requires extraordinary evidence to back it up.

[1] Unless you're Bernie Madoff and you're promising awesome financial returns with your secretive trading strategy. Except it also turned out that said strategy was a literal Ponzi scheme. Note that "we're not telling you what we're investing in" is generally one of the red flags for a fraud.
What are your favorite open source Python packages written in Rust?
That's a terrific use case, albeit super niche. I'm an artist, too. It would be fantastic to have ML help in identifying new paintings or other art (or just ones you don't know) and classifying them as belonging to an artist, movement, school, or period.

I learned this stuff the old-fashioned way, through flash cards, slides, and lots of memorization in art history class. People like you and I can tell if something is more Diebenkorn than Duchamp, but that's a specialized skill that ML could probably duplicate quite well and would be very useful for teaching art and art critique.

> The key difference between Toyota's approach and Tesla's was simple: Tesla built out their own charging infrastructure.

No it isn't. The key difference is that Telsa picked the right technology and Toyota didn't.

Tesla could build its own infrastructure because the grid exists already and building chargers is not that hard.

Toyota couldn't because building hydrogen infrastructure is insanely incredibly stupidly expensive. Even had they tried, it would have been a gigantic money shredder.

Building fuel-cell cars is really expensive, in addition the the infrastructure they are also losing money on each car.

So basically, your asking Toyota to spend billions to build infrastructure that loses money, and more billions to build cars that lose money.

The right technology choice matters!
Cryptocurrency does not help with this. Also, I asked people to name a project that isn't speculation or loans.
a 95% top marginal rate (say, on income over $1M/yr) would certainly discourage "shifting their income so that it doesn't incur income taxes". Why? Because they'd have less money that they could afford to shift around in that way.
100% of new vehicles being EV in 9 years isn’t that fast. Assuming the average vehicle lasts ~25 years that’s a ~30+ year transition that simply looks scary to start with.

Also, EV’s don’t actually require that much energy 450w 24/7 powers a 4kW/mile EV for ~15,000 miles per year. People adding AC in India are a much larger load on the electric grid than EV’s.
> I believe the problem is that, because of Julia is marketed towards scientific computing and HPC, it draws mostly from an academic user base which is not that interested in software development.

Although you have a point regarding Revise and Debugger, the last paragraph makes no sense at all. As a counterexample, Haskell drew mostly from an academic user base and many Haskell idioms have ended up in other real world *production* languages like Python (e.g. map, filter, reduce).
> It doesn't matter

That is exactly the entire point. I dispute the idea that "correctly" means what you say it means.

If Italians collectively decided that "be DEN" was the correct Italian pronunciation of the American name Biden, it's arrogant to tell them "No, when speaking Italian, you must say BYE den"

If you can agree with that even a little bit, then you agree a little bit with my larger point.
As someone who also works in this space, the idea of a single source of truth for products alone is nuts. That doesn't mean I'm not rooting for Apollo though, and I hope they find a way to bring everything together.

Feels like nowadays every ecommerce platform has their own idea of how a product is structured, from variants to modifiers to attribute sets to tags and even the nitty-gritty like fulfillment rules.

Just when you think you've nailed down a universal model you'll look at bringing on another integration that brings a unique twist to your constraints. The sheer bullshit alone that you have to put up with when working alongside all of these integrations can drive a developer mad. There have been many times when integrations release critical bugs or become flakey and we end up on the hook after the dust clears and the customers data is not malformed. BigCommerce specifically loves to surprise it's developers with API deprecations on a moments notice, what a joy to be at the mercy of.
> Even if you’re willing to devote 10 years of your life to chess you will not become a grandmaster unless you’re starting out as a child.

Well that's bullshit.

The main reasons adults don't start chess and reach grandmaster levels at the same rate as those starting as children is the lack of free time and the lack of desire to put in the effort. Those two things eliminates the vast vast vast vast majority of adults, but it's not a factor in your hypothetical.

If some adult wants to spend 10 years of their life mastering chess, and didn't have to worry about work, life, dating, children, etc, they'd have about the same chance as a child of becoming a Grandmaster eventually. The chance is still extremely low for each, of course.
Opposite experience here, it was crazy to me how fast I could prototype my number crunching on price series, how trivial it was to distribute it across multiple machines in my house and finally how easy it was to flip to gpu computation. On every step I was surprised how fast it was.

But the most important thing is the curve, not the peak rate. It's improving fast https://www.motortrend.com/news/tesla-model-s-plaid-charging... and will improve further with the 4680 cells next year.
Europe’s proposed A.I. law could cost its economy $36B, think tank warns
FWIW, employers that provide free lunch do so partly because of the tax efficiency. The IRS allows certain perks to be provided on-site "for the convenience of the employer". This argument would not apply for at-home workers, so the stipend would have to be included in the employee's income. Not a dealbreaker, but it does affect the calculus.
What Does Saying That 'Programming Is Hard' Say, and About Whom?
yes - they are well engineered, and part of this is large engines with low specific output. If you design an engine that can easily make 500hp with a tune, but instead configure it to make 300, it will last a long time.

Net of the emissions to manufacture a truck, I wonder if longer lasting drive train is actually better for the environment than marginally lower emissions? I suspect not, because I suspect that peers in the industry achieve lower emissions and similar lifespans with just a few more repairs.

In any large system, there are many problems that could have technical solutions but they're missed for one reason or another. Design mistakes occur from time to time and we can choose how we respond when they do. I want experts from other communities to join us, and they need to see that Julia will take their feedback seriously. With all due respect to your major contributions, I think we'll be better off if people in leadership roles take a more critical view of Julia, especially in public.
I think this is a bias. There has been a move from Java/C++/C# static to Python/Ruby/PHP/JS dynamic but now people are adding types back to Python, Ruby, PHP and JS. There is also a move from Java static to SML-like static (so Rust for example). Static and dynamic are not the only way to categorize languages and hide some importants things.

Ask HN: Best resources for a Covid-19 and vaccination discussion/debate?
I recently had to discuss covid-19 and vaccination with a few people that could be loosely defined as "no vax", or against vaccination.

Despite my best effort, I found it very hard to provide reliable, clear data points and/or research to use in the discussion.

For example, impact of vaccination by age group, in terms of reduction in hospitalization/death, compared to non-vaccinated people.

There's plenty of data sources out there; it would be helpful if you could share your best ones. Thanks!
