This comment seems more like you taking an opportunity to flex on someone in a comment instead of refuting my underlying point. That’s great the ruling this saying was used in was overturned (I’m taking your word for it) but citing that fact completely misses the point...
It has been said (in another cartoon) that the greatest threat to artists isn't piracy, its obscurity:

Competent is by far the most important thing. Trust is given in response to consistent demonstration of competence and integrity.

Germany is a democracy, so it ultimately comes down to the quality of the leadership decisions made by the populace.
Does it show the success of their approach? Given that new cases hit the hospitals 2 weeks after exposure it seems like it is far too soon to know that.

Also, over what timeline are we talking? South Korea has fewer deaths now, will that be the case in two years time?

I've seen a lot of articles lately drawing conclusions from the state of the world as it exists now. But this is a highly dynamic situation. Today's assumptions are next month's fallacies. We need more humility.
You can't top mitigation/supression until there is herd immunity.

You can get the immunity only two ways 1) enough people have been gone trough the disease or 2) vaccination.

South Korea must use mitigation/supression until they have enough people vaccinated or it flares up again. Complete eradication without immunity is not feasible unless you isolate whole country from the rest of the world permanently.
That didn't seem so bad. You can see with how much he was toppling pieces that he was having trouble with nerves, which would make the situation all the more frustrating. When players have an increment to play with rules should be decisive on "loss on time is a loss, doesn't matter the position". But here we have some edgecase which settles on some crazy sequence for black to ever win (if white didn't have pawns, the game would've been declared a draw)

Basically have some empathy, losing is rough & in a tournament most players are losing, for all we know he just needed to sleep on it & came around the next day
Question Copyright
The problem is that this what you get when you make a commons without reciprocity or equality.

Reciprocity means the producer/upkeeper and consumer each put something into the commons that balances out mutual needs. if only a few people can create or maintain, the many users must contribute in a lesser fashion to enable them.

Equality means that everyone create or maintain, so the burden isn't shared on a small group. If we are all farmers, we can each handle a share of a common field.

But this kind of commons is asymmetrical, and that's why you'll never see people pay the bills anywhere near close to the need. This kind of common can really only be noblesse oblige, where people with abundant resources give charity. It isn't, so people struggle.
how was south korea able to scale up their testing so fast. Where did the extra testing capacity come from. I've been really curious about this but haven't seen any good answers so far.
I think the right way to think about is to treat it like reading and writing.
In order to look for something, you generally need to know it exists. When you live in the given social circle, you tend to develop a point of view on what’s doable/achievable that’s in line with that circle. Some people are not constrained by this and have this almost built-in dream. Others have to learn to dream big.

This even happens in US all the time - kids emulate their parents, neighbors, etc. Even the access is there, but these kids don’t know it and therefore can’t make use of this access.
Yeah, not only did he throw his water bottle out of anger, he tried to appeal over something he lied about. Hard to care about him at all after seeing that behavior.

Copying is not theft, but censorship is (2012)
At my current place of work, we‘ve been experimenting with two-week “sprints” (hate the term but it’s standard, so bear with me!).

We spend half of the off-week sprint planning session “pruning” the backlog: pointing and discussing new tickets, and refactoring or deleting the oldest tickets.

If the second half of anyone’s sprint fees thin, we add a ticket (more or less of their choice) from the backlog to their sprint.

I kind of like this system, because it allows you to think in cycles both longer and shorter than the sprint. If I see some fun optimization, but know I won’t be able to fit it into my sprint, I can craft a well-documented ticket in confidence that someone will have fun getting to take care of it in the future. Backlog tickets are also a fantastic way to onboard new engineers, because the tickets come from all corners of our system: from infrastructure upgrades to copy changes.

Of course this system only works as long as you have disciplined engineers. Bad tickets will drown this system. But the “checkpoint” every other week has really been all we’ve needed to keep quality consistently high.
Ask HN: Strategies to improve after finishing a product
Hello there,
a colleague and I have just finished developing our first application for a client and we want to keep/improve upon our underlying technology. But now we are wondering, how do we know what part of the Framework(s) should be kept from the project, swapped out or removed? And what should be prioritized.
What are your strategies for deciding how to proceed after wrapping up a project and can you recommend any resources on this topic?

Thank you in advance!
Some s-curves are never well-modeled by an exponential for any substantial part (of course the exponential will be approximately linear over a short enough range but then you might as well use a line), like for example arctan. Not all s-curves are logistic functions (although in the context of epidemiology, then I guess people usually just mean logistic by s-curve).
Apple owes everything to its 1977 Apple II computer
The article and discussions about Korea seem to mainly revolve around testing and contact tracing. These are complex and expensive, and substantially more difficult to manage in a country like the US which is 7x the population, and is somewhat decentralized (50 states).

Meanwhile, the on the street observations in the article are: masks, masks, masks. Masks are cheap and easy. So let's start with masks, masks, masks first while we figure out and ramp up testing and contact tracing.

the first Apple store to reopen outside China had lines snaking out the door as many South Koreans -- almost all wearing masks

At Han River park in Seoul’s Banpo district, families -- also in masks -- were having picnics

including requiring voters to wear masks and disposable plastic gloves while casting their ballots

People are still wearing masks and mind talking face-to-face with strangers
TikTok is pretty much a carbon copy of Vine. If Twitter wasn't able to make money from Vine, ultimately choosing to shut it down, is this a sign that apps like TikTok are fundamentally unprofitable or that Twitter is just a poorly run company unable to monetize their products?
The shift work struggle is real. Keep at it, it'll get better. I try to remind myself how lucky I am to have work right now. Many of my friends don't, and that struggle is probably much worse.
I feel that Apple and Google are a bit coy when they claim their solution is opt-in only. Given that one super-spreader can infect a whole city, you need very comprehensive coverage to keep infections under control. It's as if these companies are winking at governments and saying: Hey, we've done our part, now it's on you to enact CCP-style policies to make sure that everyone has to opt-in before you're allowed to leave your hose.
> But it depends on having a very large available pool of rapid testing

Not necessarily. You can just aggressively quarantine - basically the strategy in China.

> so you can't do it when you have thousands of cases per day

At what scale? Iceland was able to do it with ~200 new cases per day per million. The majority of US states haven't had spikes this high - nowhere in CA has even come close to that.

For some reason, we've only recently started building up the volunteer armies needed to do this (https://www.sfgate.com/bayarea/article/San-Francisco-coronav...) - this should have been done on day 1.

This is pretty stupid. The cross-over between VC and parenting is ... non-existent. Maybe PG is a great person and parent, but I don't know him.

VC playbook: build a portfolio of rapid growth companies, spread a bunch of cash around; expect most to fail but one or a few are huge successes in a short time frame; repeat.

Parent playbook: no real repeatable systems, slow organic growth, everyone succeeds, likely no unicorns, one-and-done.

You cannot engineer and scale parenting.

John Conway had a teaching technique where he would appear to make an error in a talk, act slightly confused, then restart the problem now that a faulty assumption (for example) was made explicit. Second time around greater insight would be reached.

That's a very valid point. I was thinking from the perspective of the people contracting the debt. Usually you know what you would need to do if you had time and resources.

But yes, for finding existing and uncharted tech debt items, and deciding on their future, the discussion should happen somewhere else.

>allowing someone to own an idea is insane

Let's say you have an inspiration, then you work hard on that for 5 years designing up to the last detail of a [business online idea/product]. You put your service online/start selling your product. It's a hit.

Aware of your early success. $BIG COMPANY$ with thousands of engineers and millions of users copies all the details that make your idea a success.

Your early users migrate, now your site goes into the drain, along with all your years of thinking and hard work.

Are you sure that allowing someone to own an idea is insane?

Can you summarize or link to the time in the video where it is addressed?
No, my kids seem to love being home. They're crafting, skate boarding, learning to bake and cook, playing with each other, generally being kids all day.

The other day one of them said they can't wait for summer break. I asked what would be different and they said 'no school work', haha. They have about 60 minutes per day of remote learning to do. Apparently more of this would be okay.

I thought they'd miss socializing a lot more than they do so far. Instead being trapped at home with dad is similar to vacation.
It also gets tiring to have the knee-jerk defensive of PG or any other expert leveraging ina different vertical to be "if you don't love america than get the hell out".

All rich countries have been able to scale up their testing similarly quickly, once they decided it was a national priority to do so.
Python seems to be what's chosen next; couple of years ago I did the UMich/Coursera course "Python for Everybody" as prep for parenting a high-schooler as I'd never done any Python, good level for that.

I understand that perspective but I'm not sure the experience from over a century ago has much relevance to today. Would the Spanish Flu have killed so many today, with such advanced hospitals and healthcare, and no massive troop movements? We see flu pretty regularly and no lockdown is even proposed, as it's obvious the costs would be stagggeringly out of proportion.

Really beautiful results. It’s interesting to see Ray Tracing’s durability. In the 90s it was so prohibitively expensive (computationally), that a whole bunch of techniques were developed to achieve realism in somewhat... hackier ways. Now we’re seeing GPU support, etc.
You bring up an important and oft-discussed question. We're starting to see creators who make a living largely or entirely from voluntary donations.

E.g. Abbadon author of the incredible "Kill Six Billion Demons" https://killsixbilliondemons.com/about/

One of the things I wish Etsy had is a leaderboard of users (sellers) who have become financially independent through them.

- - - -

FWIW I'm one of the people that think that, as automation advances, we should see a massive decrease in cost-of-living and a corresponding increase in free time.

If that happens, we could see people becoming couch potatos or creators. I was going to say something about hedonists, but creating things is inherently pleasurable. I knew a guy who built furniture in his hope shop until the day he died. He loved it. He would give the pieces away. Beautiful scrollwork in wood.

Personally, I believe that's the long term solution: "Let the robots do the work and we'll take their pay."

In the short term, it's the old story: If you must be an artist either be very rich or get comfortable being very poor. You might find a patron.

The new thing on the block is, of course, crowdsourcing a distributed patron. And some people are doing that. "Ten thousand fans"

Totally, spot on. I think a great next step would be democratize the system that performs those tests and works with the regulatory institutions so new pharma companies can focus on innovation. A reasonable analog are the fintech startups that provide APIs and say essentially "were regulated so you don't have to be". That stuff is important and we should DRY it up so we don't have to copy/paste it every time we start a company.
> Often incorrectly represented as s-curves, they are the result of the inherent cost/benefit of the technology [...]

You're taking from two completely different levels of abstraction here. Tech adoption rather obviously happens in an S-shaped curve, at least sometimes. See the article for examples. And of course that shape, and its exact parameters, are the result of some underlying processes.

These two things aren't contradictory. Outside air temperature follows a roughly sinusoid curve. It's the result of the earth turning and therefore alternating between night and day. But it's still sinusoid.

And the S-curve does acknowledge state, or it would just be exponential.

Yes, there are different approaches to disease modelling, such as agent- and rule-base simulations. Unfortunately, they tend to be really bad because we just don't enough data to satisfactorily simulate societies at the level necessary for this application.
I'm not sure this is true. This attack allows reading the encrypted bitstream, but it doesn't say anything about allowing you to sign modified bitstreams.

Bitstream is not firmware. It’s gate configuration.

After searching Google, I cannot find the results of the actual study. Are they available?
I read that despite the simple measurement mechanism ("shine a light through a finger"), the accuracy is generally pretty high (+/- 2%). This document from the American Thoracic Society does state some corner cases though [1]. Quote:

"How accurate is the pulse oximeter?

The oxygen level from a pulse oximeter is reasonably accurate. Most oximeters give a reading 2% over or 2% under what your saturation would be if obtained by an arterial blood gas. For example, if your oxygen saturation reads 92% on the pulse oximeter, it may be actually anywhere from 90 to 94%. The oximeter reading may be less accurate if a person is wearing nail polish, artificial nails, has cold hands, or has poor circulation."

Cost wise? Yes it seems to, Sabrent's "Rocket Q" is about the cheapest 2TB on the market, and performs pretty well, Reads more or less competitively with the non-QLC drives from the same vendor and writes at around 2/3 the speed.

Intel's 660p range performs a little less well, but typically still multiple times as fast as SATA drives, and is generally cheaper too.
