Space Launch Start-Up Just Used A Giant Centrifuge To Fling A Projectile Into The Upper Atmosphere
Thanks, yes. I was being exceedingly sarcastic.

I do very much believe that by-and-large Amazon employees adults in their warehouses who can think for themselves.

(The weasel phrase 'by-and-large' is in there, because in any big enough group of people you'll always have a few fools, and their existence shouldn't detract from my argument.

And also perhaps Amazon also managed to hire some people with real medical / clinically diagnosed cognitive impairments and give them productive jobs. The latter would be great news for diversity and inclusion, and just general humanity.)
>“Europeans understand the need to preserve buildings like this, whereas Japan is still guided by a pull-down-and-rebuild mentality,” says Maeda

It's actually incredibly admirable that affordable, modern housing is regularly built in one of the world's largest cities. Contrast this to the biggest American and European cities, where housing supply stagnation is the norm in service of promoting "neighborhood character" to demonstrably racist ends.
What I mean is that up and down votes are also speech.

If I call myself a baker and open up a bakery, my customers will either like my cakes, dislike my cakes, or not have a strong opinion either way. They will express their opinions in a variety of online and offline forums. Some of them might be cranks and trolls. Others might be discriminatory towards people who look like me. Those people are jerks, although it is sometimes hard to tell at first. It is even harder to have formal rules for fairly and efficiently filtering out the jerks.

But the point of having a public business is that you're putting yourself out there. If you don't want to get the feedback, maybe you should be able to disable the up/downvote feature on your videos, just like you can disable comments. And I completely get why some people disable comments on YouTube, for the same reason I get why some companies will want an active presence on Facebook and Twitter but not reddit.

But if you're going to take away up/downvotes site-wide, then YouTube's same rationale should apply to disabling comments site-wide. The harm that you can commit through paragraphs of text is so much more than you can in a single bit. Coordinated harassment campaigns can use comments to doxx, to spread misinformation, to send viruses and malware, and more.

And you know what, we need to get rid of elections too. That's just a single bit you flip for a candidate or an issue. If the concern isn't the harm of the downvote but the danger of compressing discussion into such a lossy format (like how people critique Twitter's character limits as to why it is a bad platform for nuanced discussion), then voting for elections seems to be just a problematic, right?
OP here: I saw the spinlaunch video and got really excited that this was completely tractable in simplified form with basic physics. So I did the math expecting to see a huge savings in fuel mass and....it was basically negligible. I'm curious if anyone on HN (maybe even from Spinlaunch!) could explain where I go wrong. Otherwise you might find it interesting to read. Thanks!
We take it for granted but every now and then, when I think about it, I'm amazed that I can on a whim decide I want to listen to Beethoven and 10s later I'm listening to world-class musicians playing any piece I want. Imagine saying this even 40 years ago.
Is this just one more Electron but with Lisp? It seems to require web-browser, thus not a real GUI framework.
Manual means related to the hands. So manual labour is working with one’s hands or a manual transmission is operated with one’s hand. Also manuals are the keyboards on an organ where you put your hands (but don’t you pull out stops with your hands…)

However it is also easy to think of manual as being the opposite of automatic—something could be manually operated or a computer system might have manual overrides.
You don't think we have some kind of satellite like to them?
Flutter Test Finders in 15Minutes
> Los Angeles and San Diego Unified — the state’s two largest school districts, with some 660,000 students combined — have recently directed teachers to base academic grades on whether students have learned what was expected of them during a course — and not penalize them for behavior, work habits and missed deadlines.

That lesson is going to serve them well in the workplace.

Teach students that they are entitled to bad behavior, bad work habits, and deadlines? Fuck deadlines

The next generation is going to have a hard time competing in the global workplace against cultures that do enforce reasonable consequences for fucking up.
My limited understanding was that the spec was too big and too difficult to implement. Too many features apparently. A simpler version called APNG was advanced instead. Until today I had no idea it is supported about everywhere except IE11. No one seems to know... spread the word. ;-)

> An error being returned doesn't always mean there's a bug.

The bug is not the error, the bug is the unhandled error.

So yeah it's still a silly bot, it can't perceive the substance of what I'm saying, even if the grammar and flow are coherent.
Not likely. The timestamp got updated to April 2 2020 for some reason, but the article is actually from 2015 as evident by a comment on the article page and the publication date of the YouTube video on April 24 2015.

Also your point would imply that the timestamp adjusts to the readers timezone, which it doesn't otherwise I would see April 1st but it also shows 2nd for me.
What a pleasure to read…
I think you actually need a mirror to invert the tree.
>Either way, mixing justice and profit feels slimy.

It's slimy but it's still the least bad system. The alternative is the state having sole authority in compensating the victims (judging from the fact this went to trial, my guess is that they would have paid the victims far less), or leaving it to non-profits (which have limited budgets and are up against tax-payer funded lawyers).
Thanks for the clarification, but you can't really remove the fundraising from a conversation about whether the financials are justified, because that is literally one half of the topic. This is especially true when it comes to criticisms of the financials that you're side-stepping, such as >20% of the revenue not even going to Wikimedia.

To boil it down, somebody asked "are their expenses really that high" and you responded with "yes" even though the evidence says otherwise. You can name all of the individual expenses you want, but their existence does not automatically equate to justification.
Also, by prohibiting poor people from selling their own organs, it is more difficult for these folks to make ends meet in the short term.

That doesn’t sound like good reasoning to me.
Even so there's still the question of archival. FLAC is good for a master copy, but lossy formats mean you lose quality on every re-encode.
Yes, it tastes like bile though, unfortunately.
>* dynamic range compression, referred to above as "audio compression" (confusingly)

Because when you're in a recording/editing session it is referred to as compression. As is in, "we need to use some some audio compression for that last bit". Anyone within earshot would not think someone is suggesting throwing that last bit throw an MP3 encoder.
Makes a little more sense when you consider what the #1 disliked video is. Clearly google is really in touch with their audience and their desires here
In fairness, it's hard to blame a 9yo for colonialism. The author's family might have benefited a bit from it, in the sense that they lived over their own shop instead of on dirt between rice paddies. One suspects that good fortune could be overstated, especially when weighed against that family's extinction and her own travails.

Nguon's hatred for Khmer Rouge is genuine. However, she isn't foolish enough to consider herself a capitalist. The work she does now is simply unrelated to authoritarians, whether of the communist or the capitalist variety. The women's development center is more authentically anarchist than anything else.

It doesn't seem charitable to compare her either to idiot Confederacy buffs or to Miami Cubans. I understand where you're coming from, but keep in mind that her enterprise is selling scarves and purses to rich Westerners. There's only so much she can say without upsetting the customers.
Unions in Germany are sort-of mandatory. In the sense that whatever the unions negotiate also has legal consequences for non-union members. See https://de.wikipedia.org/wiki/Tarifbindung

About legality: have a look at https://en.wikipedia.org/wiki/No-show_job and https://www.nytimes.com/2012/03/22/nyregion/no-show-jobs-tai...
Uh, that is pretty bad IMO, especially after adjustments.

Im just curious, why is a Radiation oncologist on HN?
It's interesting. Isn't that enough? I wouldn't call it an obsession really.

You went to take pictures, so it must be something right?
Yes. I know people who have dumb phones but they only put the batteries in when they need to make a call.
Ah, what I meant was that lawyers should be paid for their billed hours, but shouldn't be able to earn percentages of settlements.
Not brilliant at all.

This is yet another move to make YouTube friendly to the same powers that be everywhere. This is a tool for centralized control, not a platform for everyone.

The reason they're doing this is the whitehouse is a joke. It's harder to convince the proles they should continue to be as easily mollified as they are when the proles aren't aware of how angry everyone else is.

It's hard to convince the world that what the TV people are paid to say is correct when it's clear that the vast majority disagree.
No, H1B also allows proof of equivalent work experience. I.e. letters of recommendation for employers of at least 4 years.
so I can watch youtube on my ipad without ads every 3 minutes driving me crazy. It was either get premium or give up on youtube, or maybe the ipad.

I was already using google music, and then youtube music family (which sort of sucks at least in terms of app development), so this was more an incremental add-on.
How does that prevent me from lifting it right off the framebuffer?
As an user, I look at the search results to evaluate the quality of an app store.

Microsoft needs to change this problem. Many trash and scam apps are on Microsoft Store for years. User and even developer do not want to download and push their apps in a place like this.
I've seen the same thing, and I've never enabled backups. I'd really like to know what it's doing.
Delete everything I don’t need to keep right away. (And if I have downloaded the files and saved/backed up I delete the emails as well).

Throw anything in the bin that I don’t need or something I can get easily if needed.

If a paper document might be needed for longer or getting another copy might be an issue then scan it.

I name the files and folders appropriately often appending to existing names.

Repeat a cleanup on existing documents, both paper and digital, regularly. A lot of documents loose their importance over time - either they literally expired or you overestimated their importance or have just lost value.
I guess on average Germany is just not as polarized about unions (and other things) as the US.

If you only ever look online, you would say that American unions mostly have fanatical proponents. (Because people who express opinions online are more likely to be leftist, I guess, and everything about American politics is polarised.)
“We’re faking the world burning and you’re nitpicking about the fakery…”
Whitehouse can't handle criticism, bummer.
Wikipedia wouldn't do that for two reasons. One, it would force a lot of people to spend a few seconds thinking about what Wikipedia is and is not. And two, it might prompt Google or Amazon or whoever to do what they have always been legally allowed to do, and copy the entire Wikipedia database and host it themselves.
As others have pointed out, uploaders had the ability to block voting entirely, but couldn't adjust visibility of positive/negative votes separately. There's a huge difference between a video with +10k/-10 and a video with +10k/-100k. Displaying both identically gives a deliberately false equivalence.
So I found myself in a similar position as you when I was younger. The market wasn't even remotely as good as it is now for software developers yet I thought it was going to be an industry that would take off. As such I went to work as an entry level software developer. I worked around 35 hours a week.

I DID NOT drop out of college completely. Instead I really just slow rolled the whole process. It took me 6 years and this included usually taking 1-2 courses over the summer. It was not an enjoyable time and my classes never stopped sucking. That being said I am glad I completed it and having a job really took a lot of pressure off of my to try and get the best grades. I would shot for a solid B and when I knew that was in the bag I would completely ramp down my scholastic efforts.

I think if I could give you any advice it is that life is hard, no matter the company, its location, the country it is in, the industry that it operates in, nor the people who work there be 100% what you like. You will run into innumerable challenges and situations you can't stand in your career, do not develop the habit of running away from them. Instead focus on what you can change to make them less painful. Leaving is always an option but I would strongly encourage you to not let it be the first one!

Some other food for thought, could you change your degree from just being CS focused to being more interdisciplinary? When I went to school they had a build your own degree where you could combine courses from three different colleges, for example you could do a Statistics, Finance, and CS degree. Just a thought.
I've been making my way through this book for the past few weeks; just started Chapter 20. I tried reading Harper's Practical Foundations for Programming Languages first, but it was too abstract for me, so I switched to TaPL.

What I like most about Pierce's book is that he introduces each concept with a formal, abstract definition, complete with proofs of correctness, but also follows that up with a concrete implementation in OCaml. The latter is very easy to follow if you've had some experience with the ML family of languages. I sometimes find myself skipping ahead to the OCaml version when I get lost in the math syntax, which for me is less familiar. I'm planning to come back to Harper's book later, but Pierce's book is the perfect fit for where I am now.

My only criticism is that some parts are very dated given it hasn't been updated in almost 20 years. In particular, the version of Java he discusses throughout the book (pre-generics, pre-type-inference) bears little resemblance to the modern one. And since 2002 we've seen affine types (e.g. Rust) start to have mainstream influence, among other things.

In case it's helpful, I'm compiling a list of resources as I learn type systems, logic, category theory, etc.:

Check out the downvotes and top comments on their announcement video. Frankly I'm surprised they didn't disable comments yet.

"Great to see YouTube finally protecting creators like Pepsi and Gillette"

"This is the most offensively dishonest thing you've posted even for your standard. Dislike counts were essential to spot scams, fake/bad tutorials, clickbaits and were especially important as a tool to fight back against horrible megacorporation announcements."

"To protect creators that suck, like politicians, big corporations that sponsor us, and astroturfed talentless on demand era hacks, we're preventing you from seeing how unpopular they are."

“We want everyone to have a voice, unless those voices are valid criticism or go against our agenda.”

"No one wants this other than the corporations who are getting shamed for putting out awful content that the public dislike. You are removing a key protection people have from scamming, dangerous or misleading content and are protecting no one. Stop hiding behind 'small creators mental health' like you think you're doing anything. We can all still see how many dislikes our video got. Our mental health is not protected in any fashion. The only thing you change is the public facing, and we know why you did this."

"When I was 12, my videos were dislike bombed. Not many liked them. Sure, it hurt, but I matured since then. I matured, because I was able to respond to the negative feedback my content was receiving. If not it, I would be falsely convinced of my perceived non-existant greatness. Dislikes are key to personal and content growth."
That undiscoverable, hard to learn behavior is a poor excuse for search engines hiding what should be the first and most prominent result.
> Their gross margin is 50% higher than Toyota's

> vs Toyota being an older and larger company with far more overhead due to an older and larger workforce.

Gross margin is net sales minus the cost of goods sold, hence doesn't include workforce cost.
Ah, okay. In that case it becomes

{n + 1 \choose n - 1}

What code are you writing that results in this set of possibilities?
> “Europeans understand the need to preserve buildings like this, whereas Japan is still guided by a pull-down-and-rebuild mentality,” says Maeda

Mr Maeda has a direct financial incentive to the financial preservation of this building.

I don’t see what’s wrong with the pull down and rebuild mentality. We can appreciate and admire something’s aesthetic qualities, but it doesn’t mean it has to last forever. Atleast to the Japanese and Buddhist nihilism, everything is impermanent anyways. Why try to preserve a fleeting cherry blossom or autumn leaves, when it’s meant to be appreciated in the moment.
All those Guides for Firefox 'Pro', don't really inspire confidence in the Windows Store...

I'd had hoped that Microsoft had higher standards, especially for paid apps. None of those have screenshots, link to a developer website or provide a support mail, because they are obviously scams.
Rust-prevention undercoatings aren't BS. They really work if re-applied regularly.
Absolutely crazy that the top comment on this story is a "USD short squeeze" idea after 5 hours. These amounts, 200 million, 150 million USD.. this is peanuts, a fart in the wind.

PROTIP: Anyone like Lyn Alden that is offering premium stock tips is by definition a fraud, if you can beat the markets you just beat the markets and Scrooge McDuck-it, you don't run a damn newsletter.
In the real world, where time to market basically trumps all, using the web as a presentation layer is almost a must for desktop applications because of the time and money saved.
Isn’t a GUI framework anything that lets you make… GUIs?

What’s a “real” GUI framework? Maybe you mean one that uses the provided operating system’s APIs directly, sometimes called “native GUIs”.
Yep, master form (single row or multi, row select loads children) with detail child(ren) (usually multi row, but sometimes single), direct relationship or via xref table(s). Hope that makes sense?

I don't mind so much having to write some plumbing code if necessary as long as I can get the job done.
"it seems wrong in a sense for state taxpayers to be punished "

The problem with that logic, is no-one would ever get compensation from the government, as in the end it's all taxpayer's money.
How Not to Design a Crypto Protocol/Standard (1998)
I tried finding another news story not behind a paywall about this after seeing it live, and the only other one is The Independent which claims the Defense's claim about Apple distorting (or using AI to sharpen) zoomed videos as bizarre. So much for being independent. I totally understand their reasoning, however it would have made much more sense if the prosecution could have assured that whatever they were going to show as clear as day. I'm inclined to believe, based on the Presecutor's conduct, that they will zoom in and try to state something is there that is very difficult to see.
> or even less charged words like ‘Democrat’ or ‘Republican,'”

Not sure those carry any less charge
I go to every “point of interest”. I’ve literally been to hundreds of temples and thousands of place in Kyoto alone, 996 for a year.

Places like this is only significant to westerners. It’s aesthetic to me because it’s decaying, but doesn’t mean I think it needs to be preserved.

Yeah I wonder how the format compares to this. It also wasn’t obvious whether hop supports adding data with an operation that isn’t just append (a stricter requirement for tar because it was designed for magnetic tape). It wasn’t clear to me from the table. sqlar can add to an existing archive and doesn’t require uncommon software to extract if you don’t have the right tool to hand.
This is a very active area of research. It's quite technical though so it takes a good amount of study to get into it.

How about compressing the files while building the archive instead of compressing the entire archive itself? That ought to preserve reasonably fast reads. It won't give optimal compression but in practice should do alright (and of course will be smaller than no compression).
I'm speaking in generic terms, of course. All models should be at the very least unbiased, though -- that's the least demand you can make of them (and generally an easy one to check, compared to other properties, such as having minimum variance of all possible models and such.)
This was at least as beautifully written as the piece itself. Bravo, and a point well made.
Not saying it should be preserved. The architecture is interesting. People here like architecture. That's enough.
