I agree with you. There would be some positives, too. We would get proper scientific studies on how steroids and all the other performance drugs work, their benefits, risks etc. I'm sure it would push medicine forward, long term. Banning doesn't work, people do doping anyway, but it's all underground
I wonder if bias analysis is even possible in a situation where ground truth itself is unknown.

With Israel/Palestine, the more you know, the less you know. Death estimates vary by 1 order of magnitude on either side. The oppressor changes depending on when you start counting.

It's a sort of black humor, that truthfulness benchmarks have models ranking at an all time high, all while we enter a post truth era.
The statement is true as long as all the people doing the hitting are men.

"Woman stoned to death by men" does not imply all men stone women to death.
The term Active Flow Control encompasses a surprisingly wide array of techniques [1]. Most of them are far more subtle that a Harrier like vectoring of exhaust gas.

Personally I'm a fan of "Electrically powered plasma actuators" which can use a high voltage AC source to alter how well the airflow sticks to the wing, and actively reduce drag. Here's some info I read about 2 decades ago on that approach[2] There were open source experiments with high voltage AC and lamp cord wire ("zip cord") in the year 2000.[3]

The more time goes on, the more stuff I see as "leading edge" that I read about 20 years ago. ;-)

Google search doesn't even work on mobile anymore with javascript disabled.
There's a much easier explanation.

They didn't test on it at all. It's a browser with sub-5% market share.

There are folks in Google who personally test on firefox and believe in it ideologically as an important peace of the web ecosystem, but that's not a company policy and detecting Firefox bugs does not gate feature release for most projects.
It's obfuscating it behind enormous numbers. Most accidents happen on takeoff or landing, so per-flight statistics are ideal for them. Some accidents happen in flight, so I'd maybe include hours in flight somehow. But miles and people counts don't serve any purpose.
Ok, I'll bite. Uploaded my gerbers using https://instantdfm.bayareacircuits.com/ Site does not respond for 10 minutes+ which is is not a good start. It's instant on the Chinese sites.

Quote for 100 boards (ENIG) on Bay Area Circuits, 10 days lead time, excluding shipping: $1000 ($1244 for 5 days lead time)

Todays quote for exact same 100 boards (ENIG) on pcbway.com, _including_ DHL shipping cost, 2 days lead time: $148 (shipping to Bay Area is usually 2 days with DHL, so really 4 days lead time). I've never had any quality issues and my boards have fine pitch 0.4mm BGA parts.

Yeah no, not even close. Certainly not marginally higher.

It's slightly cheaper than oshpark.com, they want $15 a board.
They will disable charging if they detect liquids in the port as a way to reduce the chance of causing failures.
Yes, that's a defense. Twice over.

I bought an MP3 album from Amazon last weekend. One of the many things I got from that purchase was the ability to copy that album, which would be a copyright violation. That doesn't make the purchase unjustifiable, immoral or illegal — my actual use for the album justifies the purchase. The possible copyright violation is irrelevant.

People will try to trick you with statements that mention something bad and omit everything good. Don't let them. Think about what's omitted. Does chatgpt get anything good, legal, useful from reading NYT? I'd say it does. For example, it gets the knowledge necessary to explain things in three paragraphs, partly based on NYT articles. And partly based on Wikipedia, which in turn is based on the NYT.

OpenAI is saying that training to providing a three-paragraph summary of recent events is fair use of newspapers, and that such training is not realistically possible without copyrighted materials. It's saying that if you make copyright violations impossible instead of difficult, then you can't use the articles fairly either. Sounds persuasive to me.

There's a second aspect, less important IMO: de minimis non curat lex. "The law does not concern itself with trifles" basically. If OpenAI made it really difficult to make GTP do a certain thing, if you have to try many times and it's not even clear whether each attempt succeeded, then the possibility of doing that thing isn't a matter of law, says that principle.
This is so true!

A JIT compiler is a big deal for performance improvements, especially where it matters (in large repetitive loops).

Anyone cynical about the potential a python JIT offers should take a look at pypy which has a 5x speed up over regular python, mainly though JIT operations: https://www.pypy.org/
Strategy heads come up with the strategy - friction. Enough friction against Firefox will let the browser still exist (essential for the claim that there is competition) but without actually being able to compete.

Middle management finds a tactic that implements the friction strategy - small "random" breaks and persistent performance issues.

An engineer would find the precise measure to implement - break the UA string sniffing targeting a specific browser.
Key part ( from
https://github.com/webcompat/web-bugs/issues/131916#issuecom...)

"This is entirely server-side UA sniffing going wrong. You get an empty HTML doc, only a doctype, with a Firefox Android UA. You can reproduce this with curl,

$ curl -H "User-Agent: Mozilla/5.0 (Android 10; Mobile; rv:123.0) Gecko/123.0 Firefox/123.0" https://www.google.com
<!DOCTYPE html>%

and it seems that this affects all UA strings with versions >= 65. <=64 work."
It should be fairly easy to add instruction fusing, where they recognize often-used instruction pairs, combine their C code, and then let the compiler optimize the combined code. Combining LOAD_CONST with the instruction following it if that instruction pops the const from the stack seems an easy win, for example.
I would be delighted to beta test. I would want to work on my spoken Portuguese so I could interact more naturally with my Brazilian colleagues.

I study French, German, Swedish, Mandarin, Japanese, Portuguese, Latin, dabbling in Polish, though it’s hard to find shows dubbed in Latin :). Someday will get to Russian and maybe learn Icelandic as a way of getting closer to the roots of English… but alas life is not forever.

I’ve written some LLM-based software for generating podcasts (www.anyglot.com, but the server currently offline). This project showed me that GPT4 is excellent at generating content in English, and in doing various NLP tasks but not translation which was better left for Google. ElevenLabs voices are fantastic but their Japanese would invent weird Kanji readings, tho that was when Multilingual V2 just came out so maybe they’ve fixed that already.
I think the solution resides somewhere in the middle: make video streaming platforms more like music streaming platforms.

Nowadays, YouTube Music, Spotify, Apple Music, Tidal, ..., all have roughly the same base music collection, competing on gimmicks like live lyrics or, for example, YouTube Music with normal video playback, or Spotify with its podcast library and sharing abilities.

This way, there is no centralization around a specific entity, but you also get to have the entire library of things worth considering to the average consumer.
I have seen it ingest 500K events/s. How did you conclude the poor perf?
Electrical car makes sense to me, when cars were new all kinds of propulsion methods were attempted, eventually one dominant technology gained traction.

There are, sadly, multiple other regions that fit the bill (Middle East, Latin America, etc), and plenty of creeps in all countries.
To your point, culture is intentional. Culture starts two places: at the top and at the front door. It's not an "aftermarket" add on. It's not "look we have free coffee". It's not passive slogans (e.g., "Be kind").

In short, culture takes effort. It takes work (and not the path of least resistance type of work).

I do mostly (1099) contract work, with an occasional W2. Perhaps it's my "feed"? Perhaps there's a bias in the size of my sample? I'll admit that. That disclaimer aside, for the most part, I've experienced default cultures. Less intentional, more reactive. Not so much teams as groups of people who have their cheques signed by the same people.

Many talk about culture and the value. Few actually embrace and execute that talk.
I do not know it that is true. Cancer tends to grow... ;)
They don't test on Firefox mobile.

Not explicitly anyway. Google's testing strategy is as it has always been: do some in-house burn-in testing, then launch to a small number of users and check for unexpected failures, then widen the launch window, then launch to 100%.

In this case, the user base in question is so miniscule that no bugs probably showed up at the 1%, 10%, and 50% launch gates.
> Airliner safety is insanely good. Just vast seas of competence, but when there’s a super rare failure, the incorrect impression people get is that Boeing (or Airbus) is just full of incompetency. Almost nothing that humans do is held to the same standard. Not spaceflight, not software, not healthcare, and certainly not automotive.

And there's good reasons for that. Spaceflight actually is regulated pretty strictly (partially, because any spaceworthy rocket is effectively a missile), and space pilots and tourists both sign up for such missions fully knowing that they will have a very significant chance of dying one way or another - there simply hasn't been enough human spaceflight activity to work out and understand all the failure modes, unlike with other forms of transportation.

Humans, unlike birds, aren't naturally wired to travel by air... they need to be able to trust their lives to a significantly higher degree to someone else behaving like they should, because unlike in a car they have zero control (or the illusion of control) in an aircraft.

Additionally, the inherent security risk of an airliner is very high: what is a widebody airplane at its core? Hundreds of tons of weight, a decent portion of which is fuel, propelled at near-supersonic speed, and only two people in control of it. Anything goes bonkers and you can get thousands of people killed and injured (see 9/11).

In contrast, cars, even trucks, have way less capability to cause damage simply because they weigh so much less. The only thing that comes close is railways, and hell I don't get what the US is doing there, there's barely any regulation compared to European standards (see the videos I linked at https://news.ycombinator.com/item?id=38725988).
Exactly. This is a failure of management.
What is it really JIT-ing? Given it says that it's only relevant for those building CPython. So it's not JIT-ing my Python code, right? And the interpreter is in C. So what is it JIT-ing? Or am I misunderstanding something?

> A copy-and-patch JIT only requires the LLVM JIT tools be installed on the machine where CPython is compiled from source, and for most people that means the machines of the CI that builds and packages CPython
well, on the plus side, the cplds are thoroughly documented, right? no struggles to reverse-engineer bitstream formats or programming waveforms. so you can write your own software to program them however you like
In theory burning high grade fuel to produce heat is stupid. CHP (combined heat and power) systems have more than 90% efficiency even with yesterday’s technology because all the inefficiency is used to heat your house.

The temperature of a natural gas flame is 2770C. Using it to heat a house to 30C is ridiculous. Instead you should run a gas turbine off of it to produce electricity. The exhaust should run a steam turbine which makes more electricity. Then a heat pump can capture more energy from the exhaust (and from your bath water etc) to pump more heat into your house. The electricity can be used to charge an electric car or run a gpu inside your house (and produce even more heat).

Heat pumps should be utilitarian and 10x cheaper, and used in multiple places. They should not be something you “invest” in with a 10 year payback time.
Nice!

Interesting theory, but that's exactly what M$ got dinged for in the antitrust suit re: Netscape.
It's just a centuries old technology, Air Conditioning and Refridgerator, used in reverse. It's been in use in other parts of the world since a very long time.

I have no idea why it's only now becoming a "hot" topic in the US. We've been using heat pumps for multiple decades in Europe.

it's an appeal to the common good. Which is persuasive and always been how i see it. I think everyone here is motivated by greed but there is a huge common good from chatgpt.being able to read news articles. Off the top of my head: fake news detection.
> I can't find specific numbers but estimates say about one in three has a military background. That's an awful lot.

Not surprising given that pilot training is really really expensive. Airlines love former military pilots because they are a significantly lower financial risk for them. Put them into type rating and off they go, it's rare that one ends up as a dud.
Also seems like a status thing to have PET water.

I have next to zero idea what the appeal is but it really seems popular to be cruising around with water in a PET bottle.

I've used a re-usable double wall "Yeti" bottle for years and years, it's 100x superior to a plastic bottle, but yeah, the plastic bottles still win in popularity. I know of whole families who only drink out of PET bottles at home, ie they won't drink tap water, only from PET bottles. They go through tens of them a week.

Anyway my point is, I bet this news will have almost no effect on bottled water sales.
provided it burns yes.

any accident that results in the releasing of that amount of methane unburnt would be horribly damaging.

Code fragments that implement each opcode in the core interpreter loop are additionally compiled in the way that each fragment is compiled into a relocatable binary. Once processed in that way, the runtime code generator can join required fragments by patching relocations, essentially doing the job of dynamic linkers. So it is compiling your Python code, but the compiled result is composed of pre-baked fragments with patches.
That sentence is not aimed at the consumer, but is a very efficient mechanism for capturing government subsidies.

A better deletion approach than soft delete
Typically the installation cost for ground-sourced is a lot higher, especially when it's not a new build. Air-sourced is the same as regular A/C and thus about as cheap to install.

You're right that ground-sourced should have better efficiency and thus running costs, especially in winter.
And as far as optimising things go this is a bit of a special case. Often you can make something several orders of magnitude faster or efficient, but when it comes to LRU you know you're already quite close to the optimal algorithm (in logarithmic terms).

Basically there's very little speed-up you can achieve with a smarter algorithm that you couldn't achieve with a simple increase in cache.
BTW, several years ago, a mix of mango, strawberry, and orange shake was spilled to the keyboard of a MacBook Air M1. It was not detected ;-) but the keyboard continue to work flawlessly, just a little sticky.

Show HN: I made a free dating profile bio generator using GPT-4 Vision
Hey there!

Over a couple of weekends, together with friends, we built a free dating profile bio generator using GPT-4 Vision.

Here's how it works:
1. Upload up to 5 screenshots from one of your dating apps.
2. GPT-4 Vision analyses your pictures, character, activities, etc. and creates a new profile bio based on pics.
3. You get a great bio that increases your chances to get more matches!

Let me know what you'd like to improve :)

> This uses LLVM's JIT which is particularly slow and heavy (16MB added to the binary size) last time I tried to use it.

Incorrect, LLVM is only used in the compile time. See my other comments for details.
> In Sweden the hardware cost around $1k - $2.5k and installation $500 - $1000. It's not a complicated task.

These numbers must be for an air to air mini-split unit with one air handler with nearby electricity, $500-$1000 is 4-8 hours of labor. That’s not nearly enough for an entire home.

A whole house heat pump with heat exchanger costs substantially more, both in equipment and labor.
I worked for a startup where I repeatedly asked basic questions to estimate the value of my shares. I never got a straight answer. So I applied to a FAANG and got in. When I was onboarding the FAANG asked what my shares I was leaving behind were worth (they take this number and use it to calculate starting bonus). I had no idea, gave an honest estimate, and later found out that I had given them a number about 60% lower than the true value. I'll never forgive the startup execs for keeping me in the dark, or ever work for a company again that doesn't make that information freely available. One of my favorite memories was walking out the door of that place.

Wigle is not a thing that people know about. It isn't a secret (at all) -- in fact, it was created in part to raise awareness about the problems associated with open-by-default consumer wireless routers.

But, like (say) RIPE Atlas, it just isn't very commonly known.

Data in Wigle is collected mostly by wardriving, which (in a nutshell) is just driving around and passively recording the information that WiFi access points are shouting about themselves to whoever is listening.

The data is collected by volunteers, but it is not strictly free. The way that the project is funded is by selling the data to companies who use it for geolocation services.

Regular folks can do some basic searches on the dataset without cost, though, which is what the author has done here.
Soft Deletion Probably Isn't Worth It (2022)

I don't know a lot about the Java JIT. But my guess is that the scenario you observed is the result of profile-guided optimisations done at runtime.

Hopefully this is a feature that can be disabled when you want deterministic behaviour. There's no reason to make it mandatory in a well-engineered VM.

What is even the thing you are supposed to reach after 10k hours? I would guess that it is essentially impossible to reach world-class performance in anything by practice alone, there will always be gifted people with a head-start over the average person. But you can certainly become quite good at something with enough practice. But also probably not at everything, there are almost certainly things that you are just not made for, where no amount of practice will make you really good.

And all things considered, 10k hours is not that much, it is about five years in a full time job. A developer with 10k hours will not even have 5 years of job experience if you take into account time programming during school and university years if you start programming as a child or teenager. With that you have a good chance of not being a bad developer but less than 5 years of professional experience will almost certainly not make you a really good developer unless you started out as one of the rare gifted ones.
