Your facts also coincide with weak leadership and very bad/recent decisions about reducing subsidies for health institutions (even cancelling a pandemic warning system that already identified strains of corona!) in favor of tax cuts for the already-rich.

That is most definitely not the fault of Canada to handle it better than the US.

Also, the chance that a non-American company will have a crucial piece of the puzzle for solving this is very big.

Good luck with your short-term way of thinking if other countries will put US on the last place on the list.

Oh! Indeed I misread. Things do align better that way.
The USG still considers it secure and that will retard forward progress.
I feel NASA's approach is right for manned spaceflight, but is not sensible for robotic missions - metal is cheap, design time is expensive. I feel the public appearance is not a hard - nosed calculation, but Is instead a pr requirement
I worked in a factory with horrible indoor air pollution for years, and wore N95 masks frequently. It's not rocket science. 3M has a 3 minute video up on how to wear one properly.

Is there anything in this video that requires an advanced degree to understand?
It’s very simple: with great power comes great responsibility.

Zoom is having explosive growth, and they very much deserve scrutiny, as half of the world is installing their app, and it’s powering now communication from random birthdays, schools to medical support.
Thank you for sharing this. That website is a gem of the past. Check out the home page:

> Some agencies of the United States Government (notably the Federal Bureau of Investigation (FBI)), want to prevent the deployment of encryption technology. They want either encryption so weak that just about anyone can break it, or they want a copy of every key used with strong encryption. This would be equivalent to a town with no locks on the front doors, or where the sheriff has a copy of every door key (just in case he has to search the house).

Reading this, I could’ve sworn that it was referring to the EARN IT act. But the website hasn’t been updated in years.
Correct. And not just for banking either. For financial brokerage APIs, a lot work the same way.
Imagine being dumb enough to fall for this.

I used this to stabilize a bunch of vacation videos with great results. It works better than the deshake filter but does require two passes.

Unless I’m mistaken, Tesla hasn’t yet met the sustained profitability requirements to join the S&P 500.

Do the companies in the S&P have a lot more capital than three years ago? They certainly have a lot more debt. My screeners for companies in great shape in terms of cash reserves vs debt are turning up a pathetically small number of companies.
It's fascinating that a whole game engine ended up being the right solution. Although, I guess I have heard of people doing the same with Unity. And I've heard good things about Godot as a project in general.

FWIW here's one more relevant option that popped up earlier today: https://news.ycombinator.com/item?id=22766639 It looks pretty Flutter-like.
This seems really disingenuous, like you care more about dissing someone than understanding the pros and cons of using this tool that suddenly is one of the only ways to connect with people.
Europe would help, Trump already backstabbed them multiple times by now.

That also means the actual machines for producing the masks, since Germany makes those machines. China uses them.

The ventilators for saving lives are also made by Germany.

Good luck with your short term way of thinking.
Prototype can and should be tested with the risk of blowing up if they want to improve rockets' reliability.

Obviously, there's not much tolerance when human lives on the line. But you don't have to test with humans.
I wonder how it would be if Rust, like Scala came with a very basic executor? For me external crates no matter how popular, seem a no-go because of them constantly changing.
Either that, or you are being melodramatic.

No doubt, that's how most people do it. But ideally you don't want your life to be one of hating most of what you're doing and then just compensating for it in a way that keeps the feedback loop working.
Zoom should have just called it 'Autopilot' instead of end-to-end and HN would have defended it to the death, despite that not actually being what was offered.
They started on some next generation engine technology in 2012 that they hopped eventually will be used on some future spacecraft that could go to Mars. There was no plan, announcement, design or money to invest in building anything like Starship.

And they never claimed they will land on the moon by 2022. Maybe fly around the moon in 2023.
Thank you! I'll give it a try.

Update: Just tried it. It seems to do some kind of blurring to smooth the vibrations over several frames instead of trying to cancel the shaking by inverse-transforming the frame with respect to the shake. I think I've tried this in my experiments before -- and I guess it's the difference between "de-shake" and "stabilization"? Sadly it doesn't really seem better to my eyes sadly, but thanks for the help anyway.
Even more so if you're already at home.
Awesome! I was thinking along these lines the other day, and picturing a “virtual conference” game where you could walk around and join ad-hoc circles of conversation. Maybe you’d see profile photo avatars for the people near you, and the further away ones would be generic avatars. I think it’d be a cool way to bring some of the serendipity of walking around a conference to online meetings. Maybe introduce a limit to the size of a circle too, so you don’t get 50 people crowded around the 1 famous person.
NATO member Portugal. If there's something fishy going on here, the US is undoubtedly the ringleader. Portugal hasn't spent the last twenty years actively trying to overthrow the Venezuelan government.
Comparisons beyond 100 years or so are largely meaningless. You're right about purchasing power, and that leads to your last point which is that what could actually be bought was so fundamentally different that attempting to do so is almost always going to mislead the public and be irresponsible. But it's one of those things that reporters and journalists can't help themselves from doing.

This is more of his automative background shining through. That's where the whole machine building the machine idea comes from.
There's been multiple people in the US coughing on lettuce, lick produce etc. Does that mean you wouldn't put it past America that masks exported to Canada will be laced with covid?
Weird example, given there's massive arguments about the Autopilot label every time it comes up.
I would think much like doping does today, marginal but when all the competitors / animals are all at the top of their game, marginal gains can be the difference between winning and losing.
My real estate agent has a @agentname.com domain which all my previous communication has run over.

Last week I got an email notice that a payment was due for a household bill. It came from mailer@constantcontact.com and contained a link to a Google Form which asked for a credit card number. The form itself even has Google's warning not to provide credit card numbers down the bottom. It never even named my agent, where I was living or what the bill was for or anything that made it believable.

I forwarded it to them and said I wanted to report some potential phishing. A legitimate person responded from their mailbox noting that they don't accept excuses like that, and pointing out the bill must be paid and noone else had ever questioned it.

I work so hard to train users about scams but I just have no idea what to do about the rest of the world.

> The crisis will end with sky high unemployment

Nobody knows this for sure.

At the moment, the official policy of the Federal (and most State) government is forced unemployment: a planned shutdown of the economy. To accommodate this, the CARES act includes $2400/month (on top of State UI) unemployment insurance, and that’s not even including the flat $1200 check. If you live in Minnesota, you’re looking at $5,360/month (!!!). The full state breakdown can be seen here [1]. In every state, the unemployment insurance is higher than the median wage. Businesses know this, and are proactively laying off their employees so that they may collect this benefit, with the intention of hiring them back once the planned shut-down ends. This can only happen if the businesses stay solvent, hence the corporate bridge loans.

Well that was a tease. I suppose the title didn't actual promise me I could read some code, though.
I haven't tried speeding up TV before, I think that would ruin some of what I like about TV (and I use Plex which doesn't have that option) but podcasts I speed up with Overcast and I've been watching a little more on Youtube (news, tutorials, etc) lately and I've really used the playback speed options a lot. Normally 1.5 is fine as long as I'm paying attention. Sometimes if I'm trying to get something down word-for-word I'll slow it down to .5 so I can keep up (I guess I'm not a very fast typer). I love being able to control it so easily.

Expat is a word to distinguish white immigrants from the rest of the immigrants. White Americans living abroad are called expats as well.
I read the article, several times and have nothing more to say to you.
The real disingenuity is using technical minutia that have plagued our industry for almost 5 decades to shit on a company that is having short term success being one of the few good methods for people to connect with each other during a global crisis.

I care little for the parent comment other than its attempt to drive my topical breakout back towards the very norm I was complaining about.
Yes, that people should have correct information to base their decisions on seems like an important hill. Even if I personally didn't expect Zoom to be end-to-end encrypted, because I as a technical person know that's difficult for what they're offering (and didn't look at their marketing pages).
That's not how alliances work in case of war.

And you are forgetting one thing. Interests, as you described it, aren't making the US a top dog as it was.

It's already ( under Trump) deteriorating faster than I could have imagined. And his actions are making it worse. Others are already trying to fill in the void and Trump is making it easier for them.

This should leave you more worried than me if you only have "interests".
Which is a really weird situation when you think about it! This gives credence to the theory I've heard that corporate jobs are "unsustainable" in that they will only hire "smart" people, but actively make their employees dumber.

Whether that's the particular mechanism or not, I think this bears investigation.
A lack of constraints mixed with a lack of real benefits.

Late-stage iPhoneOS was magical because of the constraints people were working with.

If you tell a developer, "Hey! Here's hardware with effectively no possible limits," they'll never write anything of value for it. A text editor and a way to do something you're already doing 5% faster.

If you tell a developer, "Hey! Here's hardware that's extremely slow and limited by today's standards, make something magical," they'll move the sun and stars to get you something that'll wow you.

Early-stage iOS was magical because of the new frontier offered; the constraints had mostly disappeared by then, but the ground was new and it presented what was effectively a new way to interface with the machine.
I think it’s pretty normal to care about truth in advertising. Also, there have been many revelations in the past few years about internet surveillance. And to top it off, the EARN IT act that’s currently being considered in the US Congress is ultimately aiming to ban end-to-end encryption so passions about this topic are running extra hot. Put all that together with millions of people stuck at home being forced to use Zoom meetings, and you have the ingredients for a pretty good rage cocktail!
I'm going to add that retail workers should have adequate PPE as well. Not only is it an unreasonable personal risk otherwise, but it's a major means of spread.

This is all that PDF has to say about WebRTC:

> WebRTC for videoconferencing is not supported for third-party browsers because Safari displays a prominent UI to make sure the user knows when a website is recording using the camera and microphone. Apple does not yet have a way to make this UI work in other WebKit clients.

That's a far cry from what you're insinuating.
A couple of months ago my wife fell for a similar scam. Caller on her cell phone said he was from our cellular carrier. She was sent a text message with a code, which she read back to him. Caller proceeded to access our on-line account at the carrier, using her cell phone number as the user ID, and purchased two top of the line iPhones, to be shipped to a hotel a couple of blocks from our house under her name and, of course, billed to us.

Fortunately, the carrier put the order on hold and sent her a text message asking her to confirm the order, so I was able to regain access to the account and reverse the purchase.

I called the carrier's security, told them the story and gave them the address of the hotel where the scammer would be picking up the phones he had ordered, but they were not interested in following up.
If they did it the right way, each call would be longer, and they would have to employ more people to maintain their goal of giving the minimal level of service they can get away with.
On the note of runtimes that are “outside the boxes” of tokio and async-std, I found a really cool generator lib [0] for Rust that uses async/await (and has macro API to hide this if you want) but implements an extremely simple runtime that just implements the semantics of generators. I thought it was absolutely genius and underrated.

I'm not sure I see the point either. I want to shop at my local bookstore. The one that is a 10 minute walk from my place. Bookshop seems like an amazon clone but they donate to independent bookstores. Well, amazon has smile, so I don't see how this is better. Perhaps I missed something.

What studies discuss how money flows internally and permanently out of an economy? This seems tangential here.

I recall an article/conversation long ago about how open source consulting projects keep money local. IIRC, the argument was that paying someone to develop open source software for a government project leads to that money being cycled around six times inside the local economy, as opposed to money leaving the local economy.

For example, if you buy Oracle's database (and associated consulting) for that municipal government accounting project for the city government of Smalltown, USA, then all that money leaves that economy permanently.

If instead the city council of Smalltown, USA can be convinved to hire a few weird local Perl programmers to build it that money will go into their bank account at the local credit union. That credit union will then loan out that money, and multiply it inside the local economy there. That Perl programmer will go down to the pub, and spend money there, and on groceries (and not Amazon), etc.

There are complications to doing it local (Perl programmers aren't great salespeople), but in Oregon we were bitten by Oracle and it turned out to not be cost effective at least: https://www.oregonlive.com/politics/2016/09/post_183.html. Oregon tax payers paid $240M to Oracle. Oracle settled for $100M, but let's be straight: $75M of that is Oracle software. You cannot find Oracle software being exchanged for pizza at any brew pubs here.

It seems like buying local is keeping money local. But, I never hear people talking about it that way, other than in that random open source advocacy discussion.

I cannot find that link, and perhaps it was only a dream I had, but this makes sense to me logically.

If I recall correctly they typically involve manipulating the execution stack; that's not something you can do in JS obviously.
That was my feeling as well - it’s not necessarily complicated, it’s just so niche as to not have anyone making it. Today I found this GitHub repo which I may try tinkering with on the weekend:

This is a cool site, and I like the clever way it "works" on my desktop.
The fundamental conceit of csrankings.org is right in the name. US News (and anyone else) does just as good a job. And always will. You can matter have your measurement gamed. Or you can measure in obscurity. Or you can matter and not measure. Pick one.

For undergraduate, just go wherever is cheapest with a reasonable curriculum and non-joke professors (decently difficult to hack: couple hundred citations and also real industry experience). Emphasize places that will also teach you non-CS skills (a second major, a great network that in addition implicitly teaches you the right type of communication skills, etc.).

For a masters, just don't.

For a phd, go with the best advisor you can find and finish fast.

Ignore rankings. They exist to be hacked. And academics are great hackers.

Also, Germany did the same thing to Switzerland. They sized masks destined for Switzerland

So Germany is okay when they do it, but not okay when they are on the other end.
Hi @willvarfar: Just to avoid any confusion, TimescaleDB's compression is available in our community edition, which is fully free to use. Once you specify some compression configs, it's automated and transparent.

https://www.timescale.com/products/features
https://docs.timescale.com/latest/using-timescaledb/compress...

(The "community" edition is available under our Timescale License. It's all source available and free-to-use, the license just places some restrictions if you are a cloud vendor offering DBaaS.)
I'm no expert, but I am sure the only pulp used in a N95 respirator is the box they put the 10 or 20 masks in. They can easily replace that with a bag.

Just as well really. Him cashing out big time would not have been the fairest of outcomes.
You mean the 68 countries that already restrict the export of masks?
Romans were far more tolerant of official corruption for one. Appointment to government positions and influence over government officials were pretty much blatantly for-sale.

It might sound cheap, but discussions of the "basic necessities" of anything so often just overlook obvious counterexamples.
You've probably seen this, but reposting:

https://blog.timescale.com/blog/building-columnar-compressio...

Our own experience was that most users were getting 3-6x compression running TimescaleDB with zfs.

With our native compression -- which does columnar projections, where a type-specific compression algorithm is applied per column -- we see median compression rates across our users of 15x, while 25% of our users see more than 50x compression rates.
Agreed. The post was written for an audience that doesn't care about exact frame editing.

Would the following work?

# Calculate the exact start time (in s.msec format) via:
START = start_frame_number/frames_per_second

ffmpeg -ss $START -i video.mp4 -c copy -map 0 -frames 1400 output.mp4
Haha, yeah I can rationalize almost anything and make it sound plausible. It's a talent of dubious merit.

I think the take-away here is there's no reason to assume that both shifts would have equal skill - likely there will be some differences, and it's a question of how much and why. It would be odd if it turned out there was no difference at all.

I would love to know what percentage of people are infected by touching their faces with their hands. My non-expert guess and I could be totally wrong, is that it is pretty low, but much higher to catch it by being near infected people indoors talking and breathing out the virus for an extended period of time.
Giving it to some random caller does not make me any more secure - so it would seem that the rational approach is to distrust any incoming call that mentions the issue, as it does not belong in any security challenge.

Everything that isn't authenticated (like CTR mode, which is what was supposedly "recommended" here) admits the potential of an oracle attack, so what's interesting to me here is what's distinctively bad about ECB in this setting. And: I'm not saying ECB is OK in this setting. I'm saying "it's not PenguinVision simple" and "what makes it not OK is probably interesting".

You know more about the codec situation here than I do. So, you tell me! What should I be looking at?
