Air resistance applies a force opposite to the direction of travel (retrograde). At any given instant, the effect is to not change your direction of movement, but decrease your speed of movement. A retrograde force will always lower every point of your orbit (except the exact point where the force was applied, which would remain on your orbit). Since your orbit already has a point that intersects the surface of the planet, your new orbit must also intersect the surface.

One minor complication: Technically, air resistance applies a retrograde force relative to the direction of the wind. At low speeds this might actually increase your orbital velocity. However, the speeds where this is relevant are so small that they are not worth consideration.
I dont have the FaceBook app on my fresh Android phone. There's still the com.facebook.katakana service running, which I explicitly blocked via NetGuard. But they are still the tracking pixels and cookies remaining, via all the webpages with their Like button integration, and Google/Mozilla conspired to block browser extensions to disable those.
How much force is exerted on the rocket / payload when it is released from the vacuum chamber — traveling at full operating speed for an orbital mission — and smacks into the atmosphere?
Technically the regulation says that charging is allowed, it just has to be the same flat fee across the entire SEPA zone, whether it's domestic or international. Most banks found domestic fees unpalatable, so they just made everything free. In this, as many other things when it comes to e-payments, Germany seems to be a bit of an outlier.
It a uniquely American stupidity that somehow everyone just lives with. The concept of overdraft doesn’t even exist in normal consumer accounts anywhere else in the world. The first thing I do when I open an account here is to disable overdraft - but then you have to pay return cheque charges by whoever was trying to charge your account.
> the only instruments we can build pick up particles

In general, this is not true. As in, there are experiments we can build that demonstrate that the wave nature of light is the true description.

Where people get confused is that practically all instruments are made of matter. Atoms, or at least a plasma or even individual particles, but matter nonetheless.

If "particle behaviours" is a property of matter, and you have only experiments made of matter, then this tells you nothing about the behaviour of light, which is not matter.

This is like basic experimental science 101. Beginner stuff.

Isolate the thing you are testing, and test it, and only it.

This is hard to do, but not entirely impossible.

Try harder to be a scientist and stop reiterating woo that you picked up from textbooks that copied it verbatim from people that died nearly 100 years ago. (The same people that thought that a human looking at an experiment was somehow an essential aspect, leading to a century of stupid people arguing about whether a brain is necessary for physics to occur!)
A space elevator is an example of spin launching. But it's a particularly unstable one.

I find it hilarious that Americans will tell you about the great discount/cashback they get, then in the next post crypto advocates will tell you that crypto currency can avoid the insane credit card fees.

It's almost like the two things are related, but few people seem to link them...

In Europe and Australia, caps have largely fixed the latter, at the expense of the former. Seems better all around.
Jbig2 sounds like a bad option for a photocopier. They should not attempt to parse what they're copying.
oh another vibrator open sourced on github. how vibrant.
No, as the need to learn new things is going to be inevitable. Even if you have been a Java dev forever (and that language will last your career), I know a couple Java programmers who took months and months to find work in this market as they didn't keep up with the latest in Java.

Keeping up with the latest tech is more properly compared to diversification. You are not abandoning your old skills, but you are adding some new ones that have a good chance of being valuable in the future. You may end up learning something worthless, but as long as what you learn is mainstream, there are probably jobs for it.
Human experimentation is a Nazi trademark.
If a, b, c don't compel you, you may do fine with keeping an engineering journal or a personal wiki if all you need is a place to collect your knowledge.

However, to advocate for blogging I've got 2 points:

1. Refining your opinions -- related to becoming a better communicator, I think that forming a cogent opinion post requires you to really think through your thoughts, opinion, and experience on a topic. As a project it can be a great learning exercise, I find that I gain a much more solid understanding once I feel the need to back up my opinions with experience and references.

Which brings me to 2. Learning in public.

Taking the time to write up a good post and share it around exposes you to people who will agree with you, challenge your ideas, and importantly learn from your experience. It's a way to find a community and give back to it, and gain more in return.

Does 1 help you with c? Yes. Is 2 also networking, branding, maybe building a following? Sure, if you try at those parts.

Most the blogs that I want to read care a lot more about concentrating knowledge and experience so they can learn from and help grow others e.g. Julia Evans or Alexis King
Oh don’t worry Zillow, in places like Sydney young people have already been well and truly priced out of the market. Our median house price for the massive ‘Greater Sydney Area’ is a massive 1.5 million dollars. With an average salary around $60k something is already fatally broken with the system.
ARC in Swift doesn't have runtime part, retain/release code is injected at the compile time. It doesn't have ie. cycle detector running periodically or anything like that. If you define this setup as GC then by this definition Rust's borrow-checker is also a GC because it works the same way - by injecting static code during compilation (but has different rules).
Well, anything to keep the income, uh, incoming.

If all else fails, there's always Intel and AMDs own backdoors to investigate and blame.
The results are so crazy different that either Snowflake or Databricks are wrong or outright lying.
A gravity wave occurs at the lowest of the lowest of low frequencies. In order to produce such a wave the object resonating would have to be many many miles long and be stronger than any material known to man as well as incredibly heavy. Think of a very long cable woven from a neutron star. That’s about what it would take :)

The concept has of course been written about a fair bit on science fiction. The dark forest trilogy comes to mind and used a gravity wave generator built into the hull of a massive ship whose purpose was to alert alien life to the existence of the earth.
Unless, of course, you have some algorithm that depends on signed zeros. Which is basically the same with all the optimizations the article complains about.

I'd suggest -ffp-contract=fast is a good idea for 99% of code. It's only going to break things where very specific effort has gone in to the numerical analysis, and likely the authors of such things are sufficiently fp-savy to tell you not to do the thing.
Among other drawbacks, that would interfere with satelites
> Crucially, the mRNA vaccines have a very similar effect on the body to previous vaccines. The fundamental mechanism is the same: stimulate an immune response to a particular pathogen without actually giving someone the pathogen.

If I started a new car company, and it put out it's first mass market vehicle, would you accept me saying "yeah, it's a car, it works like every other car out there, it has 4 wheels and drives down the road", would you assume it has the same reliability and safety record as an equivalent Honda or Toyota?

> Also, the way we know that it won't have adverse effects in the future is that the vaccine doesn't persist in your system. If it's going to harm you, the harm will be in the short term. It can't just pop up again in 6 months.

If someone was diagnosed with cancer (or an autoimmune issue, or dementia, etc) today, when did that diagnosis become inevitable? Yesterday? Last year? How do we know that the harm will manifest itself immediately?
Considering that the next figure is a computer simulation from the same citation, yes I believe they have heard of such an amazing tool.

I chalk up the physical robots to a bit of a PR stunt. Cool little robots is quite a bit more endearing than arrows on a computer screen. But that said, implementing such a system in physical robots could also be a kind of sanity check to ensure you aren't cheating the simulation by some kind of fault in your simulation. It's quite easy to share information between agents that you don't want being shared without realizing it. Something as simple as being a little careless with global variables could spoil the whole thing.

I wouldn't get so worked up about it.
How does rr work with multi-threading? I would imagine threads can mess with the order that syscalls are executed.
> fling chunks of the moon into space. I mean... I'm not sure why you'd bother

Hmm. The Moon Is a Harsh Mistress builds a compelling case to do so.
Confidential is the lowest level of Classified. Classified is the overarching term for all the above except FOUO.

e.g. all Secret is Classified but not all Classified is Secret.
Free money?
Is there any algorithm that depends on signed zeros? I'm not aware of any.
> 20 minutes to find an expert?

They'd had an expert in previously who came back and contradicted the prosecution's statement that enlarging won't add "pickles" (quickly corrected to pixels) to the image. The judge allowed the evidence after the prosecution followed the proper procedure.

> But I've never heard that iPad pinch-and-zoom does this. It would be surprising if it's more than plain old interpolation.

There are various methods that can be used, any of which can add new pixels and or colors, the prosecution expert didn't actually know the details. When you have a couple of pixels that's claimed to be a gun, it really matters whether it's an image artifact or not. Also, the alleged gun is somehow in Kyle's left hand (he's right handed) and does show up as the same temperature as his body on the infrared image of the same scene.

> Not to mention the defense lawyer clearly doesn't understand what the hell he's talking about

Nobody there knew what they were talking about, which is why they got experts to testify. The prosecution hasn't been following court procedure and has gotten chewed out for it repeatedly because they're trying to pull illegal tricks and are getting called on it.
Fine, but if you don't get the vaccine, your insurance shouldn't distribute the burden of covering medical costs for you if you should require hospitalization. Right now, that's what's happening. It's not just "my body, my choice". It's access to vital healthcare for entire communities, and it's being plugged up by people who want to make a political statement.

It's similar to not being able to legally drive if you aren't wearing your seatbelt. People bitched about that, too.

There need to be consequences for this burden people are spreading to others.
Since finding it pretty much means being able to see it, would we ever be able to find a tiny black hole? I would expect its size to be sub-kilometer and if it's at its aphelion to be pretty much invisible.
The keyboards in System76's new models (any with their custom EC firmware) support up to 4 programmable layers

idk if they actually work with QMK, but they use the same configurator as their custom keyboard for desktops, which can run QMK

The Plasma desktop environment lets you modify window behavior on a per-application or per-window basis OOTB, including having them skip the taskbar.

Interesting. I live in a very rural community in a neighborhood that is incredibly diverse, not only racially, but by age and religion too. We get along just fine.

Perhaps this area tends towards republicans because folks around here aren’t overly hung up about their differences and seem more to focus on their similarities. They also seem to be more capable of self-sufficiency and less day to day reliance on the government…even those with modest incomes. That tends to be the GOP messaging (at least around here) and people are drawn to it. Their life perspective tends to run counter to the dem messaging of division and government reliance.

We also have two different fiber optic ISPs willing to provide internet to our homes. I assure you there is definitely no lack of information around here.
"Impact: fixed processes that led to 8 hr outage" seems like an easy case to make.
No, I didn't. Maybe if HN had an effective system for mods to message users...

It's strange to me that voicing an opinion about predatory businesses and lamenting the fact that these are supported by an investor class smart enough to see their predatory nature would be labeled as doing "ideological battle". Can you tell me what my ideology is? I'd love to know what ideology has an exclusive on calling out predatory business models and the people who fund them without any apparent moral qualms.

In your other comment, you stated "It also looks like you're mostly using HN to argue about ideological and politically inflammatory topics." It's quite confusing. If there are "ideological and politically inflammatory topics" being posted on HN, any comment on them could be also conveniently deemed "ideological and politically inflammatory", no?

You don't have to ban my account. I'll do you the favor of logging out permanently as apparently, Hacker News is a place where "it is difficult to get a man to understand something when his salary depends upon his not understanding it" determines what's considered acceptable.

Before I log off, one final note: I've traveled extensively in SE Asia (and in "poor" countries in other parts of the world) and have friends in places like the Philippines, Vietnam, Indonesia, etc. If you get a chance, I hope you can travel to some of these places. Try to spend some time with people who don't have much and maybe you'd understand how utterly harmful and shameful these predatory businesses are. Perhaps, having made real-life connections with the people targeted, you too might even see a post about these predatory practices and feel the urge to speak up about it.

Okay, sounds like you have a pamphlet you'd like me to read.

I'd simply state that many public health measures are mandated. This is just another one.

You can't drive drunk, you have to wear a seat belt, you can't build buildings out of straw or sticks (you silly pigs), you can't pour sewage into you can't have unprotected sex without disclosing it when you know you're HIV positive. You can't sell black tar heroin.

You can't fly into various countries from a country with yellow fever without proof of vaccination against yellow fever.

You can focus on that "99+%" survival rate if you like (which involves ignoring that the actual survival rate greatly differs between different cohorts), but if you don't take into consideration the considerable amount of resources and effort that healthcare systems put into achieving that, you're only deceiving yourself.

Also - hospitals have limited capacity designed for non-pandemic times. Vaccination against Covid prevents excessive demand from a preventable severe illness overwhelming healthcare systems, causing even more excess deaths, even if they didn't die from Covid, they died due to Covid.

Lastly, as members of society, we have obligations to other members of our society. Pay tax to contribute to shared infrastructure, follow the laws passed by representatives of your country's voters, etc.

I'm quite happy for people to remain unvaccinated if they ensure that they can never pass it onto others, and if they waive their rights to medical treatment if they become ill.
Air Drop makes me smile every time.

2022 Mercedes-Benz EQS Sets New Edmunds EV Range Record
(I have not yet publicized the implementation because I still need to check its performance in real-world applications. But quipping '370% in microbenchmarks with ideal branch-prediction and caching' seems appropriate considering that's no less than what the linked post does.

That being said, preliminary instrumentation indicates the tradeoffs made were correct.

My main point, however, is that for such low-level, essential subroutines, assembly remains the correct implementation language; c is still inadequate.)
[1] I would not say Commodore has been erased; for example, Commodore is included in the Computer History Museum, which also premiered the movie "The Commodore Story."

[2] Citation? The references I've seen indicate that Apple stopped selling the Apple 2 in 1992 (though a IIe card for the Mac was sold until 1995) and that Apple's revenue increased until 1995 (remaining profitable through 1996) and didn't "crater" until 1997, the year that Steve Jobs returned (and fixed various problems including a confusing product lineup and Mac clones that were eating Apple's lunch.)

(Note: The Apple article on Wikipedia could really use some improvement and some better source references.)
I don’t know if anyone ever told you before but you have a real talent for explaining thing clearly and simply!!

You should write technical book or something!!
Self-determination is a collective right, not an individual right. Distinct groups of people get to structure their society as they see fit. Individuals within that a society must abide by those rules.

International law, of course, recognizes individual rights as well. My point is that when a society doesn’t abide by those rights, it’s not the business of other societies to do anything about it. Self-determination should trump in almost every case.
An an avid gamer that spends a lot of time and money on video games: fuck that.

It sounds fundamentally busted if a competitor can submit benchmarks for someone else. TPC is great in general, but I didn't realize it had such a gaping flaw.

TPC submissions take real time/$/energy/expertise, so I don't know anyone who has ever done it casually. Ex: It was a multi-company effort for the RAPIDS community to get enough API coverage & edge case optimization for an end-to-end GPU submission on the big data one (SQL, ...), and even there the TPC folks made them resubmit if I remember right.

Also, note how the parent's response did not actually answer 'audited how'. Pushing the work to the questioner is on the shortlist of techniques studied by misinformation researchers. I'm a fan of both companies, so disappointing to see from a company rep.
Databricks and snowflake should pay an independent third party to re-run these. In-house benchmarks by either company don't count with results this different.
Uh. What? This might be one of the single most ignorant comments I've ever read on HN.
Ah yes I remember trying out Redis with telnet, it was helpful at the very beginning. Thankfully command-line clients came around soon enough. Also, the protocol as it is today was only introduced in Redis 1.2, and wasn't around at the very beginning.

It's true that the parsing time is small compared to the network round-trip, but Redis being single-threaded means that while it's parsing a large nested command and allocating memory as it goes through it… well nothing else is being processed.

I'm pretty familiar with the costs of parsing this protocol, being the original author of the phpredis extension. Written in C, it's a high-performance client whereas pure-PHP clients can't use the same zero-copy tricks or careful memory management in general to avoid repeated calls to strlen/malloc/memcpy/free (in that order). In Webdis – another high-performance Redis tool I wrote – protocol parsing with Hiredis is similar to HTTP parsing in the sense that it's where most CPU cycles are spent.

I'm not really sure why Salvatore chose to keep the text-based protocol when his focus was so often on performance. I'm not aware of any attempts made by him or other people to change the protocol, but it would be interesting to see how much of a difference this could make.
It could work, assuming you can shield yourself from the inevitable explosion once that mass impacts something.

FYI: Australia has income tax incentives for owning property roughly equivalent conceptually to the effect of Prop 13 in California.

So houses are a tax shelter, not personal shelter.

Miles was, and is well known outside of the US. In his autobiography he talked about how much he enjoyed playing in france during the late 50s, because there he was treated like a star, and not a 'black man' like back home.

Life After Java 8
Hello,

I wrote a small presentation about new features of Java language, especially the ones introduced after Java 8. I tried to pick the most relevant ones for our day to day coding.

In the GitHub repository, there are some sample code and the presentation in pptx and pdf format. The code works on Java 17 without any configuration.

Oh boy no. Canada has only a handful of banks, minimal competition (they make money hand over fist) and customers get bent over on a regular basis.
