Mate, I haven't felt as happy reading a comment on this website as when I read this comment of yours. Keep up the excellent work and I hope you find a lot of success!
I’m guessing all of Google’s internal apps are only tested on Chrome, with plenty of Chrome extensions, which means that all of the developers have to use Chrome to make the tools work, and at that point, switching back and forth between different browsers is a pain so none of the other browsers get the love they deserve.

The attitude of “it works on Chrome, I don’t care about anything else” is fairly widespread anyway. Just to stem the tide a little bit I’ve been developing on Firefox and Safari first, and then checking Chrome last.

I got bitten before when I made a browser game, and then noticed that it was all sorts of broken on Edge, even though Edge supposedly had all the features I needed. It turns out that Edge did have all the features I needed, but I had accidentally used a bunch of Chrome features I didn’t need. The easy way out is to turn things off when I detect Edge. The hard way is to find all the broken parts and fix them. So nowadays, I don’t do any web development in Chrome.

I don't think it will directly track leg movement, but it tracks sounds, so if you're shuffling the sheets it could possibly pick that up. It's a very highly rated app and I've used it successfully myself.
Creating Your Own Git Server
I wasn't clear I want to route the output of a programs like Abeltron, Audacity etc and maybe route more than one audio source

And don't get me started on the total Goat Rope that Windows Audio seems to have turned into - for what ever reason a lot of laptop's using realtek sound has been broken since an update about 6 7 months ago
Just speaking from my own expedience, I had advanced (jr year) mechanics before diff eq... but admittedly was taking it early. It was doable but tough.

Greens function were new to me in grad school. Grad school mechanics had be learning math I didn’t know before too... can’t recall what it was at the moment.

And then the advanced AMO class had some more math I hadn’t seen.
What do we know about the risk of dying from Covid-19?
https://github.com/janestreet/bonsai is making some interesting distinctions between "UI state" and "model state". They're kept separate and they're working on utilities to manage the use of composed components.
Ask HN: Freelancers, are you lowering your rates?
I'm curious to know if any freelancers out there are either lowering their rates and/or being asked to by clients? If so, by what percentage?
Oh wait...THAT might be the problem?? I've been having that issue too! I have to cut the cell content, delete the cell, and then paste the cell content back in in order for the row height to appear the same. It never even occurred to me to switch browsers, I thought it was an issue with Google Sheets.
I don't think a crypto mailing list is the same as "gam3r" subreddit, but it wasn't that rude overall.

It was the tone that they "dont understand" when in fact Cloudflare does understand crypto and performance very well, and went so far as to dive into kernel code and submit patches that fixed the problem that others didnt even realize existed. Even so I agree this isn't worth such a big discussion.
Oscar employee, here. I haven't been involved in the company's COVID response (having joined only a few weeks ago), but the efforts of those I know on these tiger teams have been tremendous—spinning up risk assessments, testing locators, and more for both our site (see below) and wider usage (of which this open sourced work is one instance).

Many such teams are still in the thick of it, so juicy hackernewsy engineering write-ups (around the joys of high-pressure requirements definition, slicing code out from a private repo for public distribution, and so on) will have to wait—but hopefully, there will be some public form of them made available when things settle down.

https://ouraring.com/ is pretty awesome. I've started sleeping more, at more consistent times, and consuming less caffeine and alcohol.

$75 off - http://ouraring.com/partners/rohannatraj - doesn't benefit me, just a coupon I received myself.
the problem there is that our drug sector is so bloated that we'd need to pay 10x-1000x for every drug produced domestically. the government can't just mandate a production number and a price, as then that's essentially state control (and susceptible to corruption).

we really need drugs to move more rapidly through the cycle of being novel and experimental to patent-unencumbered commodities, and open up competition in hospitals (i.e., don't let them charge $400 a pop for their monopoly tylenol). in fact, we need a more vigilant and active FTC and a high-functioning commerce department to stamp out monopoly behavior and encouurage competition across the board.

i'm also ok with setting up tariffs, with mandatory sunset provisions, to allow time for international price equalization of all sorts of outsourced industries. global markets aren't yet competitive and equitable (for instance, pricing in pollution externalities on manufacturing and shipping), and we won't get a structural move to re-industrialization without it.
I'm not abolishing my family. But by all means, if you don't care who will?

ScreenHero was amazing, beyond happy to see it come back again.

Love that it is still blazing fast. Love that awesome features like multi cursor are still very much a thing.

Congrats on the re-launch!
The hospitalization rates for younger people in Italy and NYC don’t paint such a rosy picture though. While deaths are rare, it’s still a very nasty disease for many younger people, and we don’t have much data yet on potential long term effects.
The problem with services using the user-agent to determine whether or not to allow a client access to a resource outweighs any benefit. I'm in the "it was a mistake to include this in the spec" camp.
Submitted title was "Deep network in the browser converts to 3D any image of a person/cat/anime face". Changed now.
I remember, when Firefox still had a menu bar, you could actually select a different named stylesheet from within the browser! It was in the edit menu.
Absolutely there is huge sampling bias in testing. This is true over the entire world.

No one knows what percent of the broader population in Italy have been infected, asymptomatic or otherwise.

We can hope the number is closer to 1 million or 10 million than it is to 100,000. Because you can’t hide the severe and critical cases, a wider incidence means a lower severity. But we have no scientific data on this absolutely crucial statistic.

The only proxy we have is the positive rate for tests that are performed. Recently it was reported that the positive testing rate in NYC was as a high as 28%. This implies that the general population infection incidence is extremely high, e.g. several million cases in NYC. Ideally you would want to see a positive test rate closer to 1-3%.
As complex systems grow, The Rules™ grow into tangled conflicting messes. The mundane, every-day experts who have to live inside those complex systems must develop, among many other skills, a sense of knowing which rules to follow and which rules to violate in order to get the work done.

After this incident we can say, they clearly violated this rule. They cut corners. However, we have no clear view of all the incidents they prevented in the past because they violated that rule. We cannot see that there were twenty other times when violating this rule in exactly this way was exactly what kept things working.

This is the nature of hindsight bias. After the fact, it's completely obvious exactly which of the conflicting rules should have been followed. It is obvious because we now know the outcome.

If you're in the thick of an incident making high-pressure, and high-consequence decisions under duress there is no way to actually predict the outcomes that will become obvious only after-the-fact.

Taking a balanced approach is good universal advice for everything. But in this context, it misses the point of blameless retros.

Our cultural norm is to stop investigations once we find the culprit who cut-corners. The consequences of that systemic habit are that we fail to learn and understand all of the complexity that actually contributed to the failure. We cut short our own learning. What's more, we also effectively teach everyone in the system to conceal or withhold their full understanding in the next incident. So we learn only the most shallow details about what actually happened for this incident, and we suppress what we might learn in the next incident.
It's not about living in fear. We're not quarantined because of fear. We're quarantined because of knowledge - we know how contagious this is, we know what the hospitalization rates are, we know our medical resources will be quickly depleted and we know how to slow the spread until we're better able to respond. The question we need to ask ourselves is why weren't we prepared?
I've found it's surprisingly hard to get a satisfactory recording setup - noise, volume, echoes.
While it can be deadly, around 80% of cases are mild to moderate, and people recover within a week or two.
Balance of Power: Personal Power
I wonder how the safety of "AirBnB type marketplaces" is looking right now.
I think the other comment puts it well. String theory is a model builder or a model factory. Models are testable, factories should be viewed from the point of view of the user. Physics theorists are the users here, some think the testable models it puts forth are rubbish, others think it puts forth good models. Would you say Math itself is rubbish because it allows for such models to exist? I don't think so. I think string theory (as a model factory) might be the best tool for finding minimal elegant testable theories that satisfy known constraints, after all isn't that what science, especially Physics is really doing?
Global Summit on the Coronavirus
One of the reasons I bought my Fitbit is to look at my sleep patterns. (In hindsight, I only look once every few months)

The data is surprisingly accurate, and sleeping with a watch on doesn't bother me one bit. (I use a silicon watch band, the dressier watch bands would probably bother me.)
I strongly agree, while I'd rather run Linux, this is the reason I can't get off mac. I have restored backups at least 5 or 6 times over the years, including last week. Once, I had to jack around with wiping a fresh Catalina before the restore worked, because of APFS/HFS issues, which the restoration UI complained about. But it has always worked when I need it. Post-restore, I'm exactly back where I was. With hundreds of gigabytes of geospatial data, and a decade of software projects, I can't start from scratch without losing weeks of time.
You can use the Figma Linux wrapper to solve that issue. I have thrown my MacBook in a corner since them. I'm fully designing and developing on Pop_OS since 3 months.

For the past decade or so, the Republicans have generally been the ones who've worried about America's industries being offshored to China and the Democrats have been the ones who've downplayed those concerns as xenophobic nationalism from people who're stuck in the 50s. I've no doubt there'll be an attempt to rewrite history on this, but insofar as this has been a partisan divide it's been the other way around.
There are perfectly valid use cases for third party cookies that do not involve tracking. Our business offers an appointment scheduling widget, it needs cookies for user sessions, and those cookies are third party because the widget is commonly included on a web page inside an iframe.

Chris Bourg, Director of MIT Libraries, has a lot of nerve to make this statement in the article:

“Ubiquitous access to open digital content has long been an important goal for MIT and MIT Libraries. Learning and research depend on it.”

Maybe Bourg should recall back in 2012 how his library aided and abetted the Secret Service's plan to have Aaron Swartz inappropriately charged under the federal Computer Fraud and Abuse Act.

As many readers of hacker news will recall, rather than serve time in a federal penitentiary for his brave act of civil disobedience, Swartz sadly chose in January 2013 to take his own life instead.

Swartz then became a martyr for the cause of "ubiquitous open access to digital content" ... rather than just "ubiquitous access to [already] open digital content." As a result, he would have been a much better spokesperson for the cause of "ubiquitous access" than a phony like Chris Bourg.

Swartz is today rightly regarded as one of the heroes of the 21st century civil rights movement. Bourg, on the other hand, is just another overpaid university administrator who collects a large (and largely undeserved) salary that has helped put millions of American college students into several trillion dollars worth of student debt ... which several presidential candidates now want taxpayers to bail out!

Bourg should also check in with MIT police to find out how often they are called into the library (post Swartz' arrest) to threaten members of the general public with arrest for the crime of using his library computer terminals "for more than hour."

Thankfully, those of us who are not on the academic dole now have libgen and scihub for our "learning and research."
That response from the dm-crypt mailing list is unreal.
The data was shared willingly within the understanding of the person making that decision. Do people really understand how much data in their day to day life they have “willingly” shared?
> Banks can get loans for free, and pass that onto credit-worthy businesses.

Why would they? And who's creditworthy in your world? Are banks going to be able untangle every single contract you have to see how this affects you? Especially in a world where every single customer and every single supplier is going to look at renegotiating contracts with you? The general notion of creditworthiness implies a relatively static world - changing everything is going to make everyone questionable from a credit perspective.

> Less credit-worthy businesses can get loans through the SBA through the stimulus. The government's existing programs (assuming the stimulus passes) will breach the extra 90 day gap for most.

Then why do we need this at all? Why can't we just have the affected businesses borrow from the government? Instead of A not paying B and B borrowing from the government to cover for not being paid, why not just have A borrow from the government so that we don't have to modify every single contract in the world in a highly unpredictable manner and freezing the entire economy?

> You're assuming the economy is humming along right now. It isn't. Large parts are shut down. Some parts aren't.

Most parts aren't shut down. No one is predicting a GDP decline of over 50% or an unemployment rate above 50%. Some parts are shut down, others are doing okay.

> Those frictions are causing massive structural collapse as we debate.

And this proposal literally is the massive structural collapse - it's the equivalent of eradicating COVID-19 by killing everyone.

> Also: In most cases, up-front payment is fine while everything else is shut down. I understand the importance of credit. But the alternative is worse. If this continues for 18 months, virtually all mortgages, private and commercial, will be under water. Virtually all renters will be evicted, or rents will have gone down many-fold. Etc.

Everything isn't shut down and again your business is toast if you're forced to make up-front payments while you're not getting paid. This is silly considering that there's a perfectly reasonable alternative of bailing out from the bottom up.

And no, this isn't continuing for 18 months, that's completely absurd. The economy will simply have to go on if an extended shutdown fails to work and the economic pains reach a certain threshold. Also, it's not honest to compare the impact of a shutdown without your proposal for 18 months with the impact of removing credit from the system for a couple of months. The economy as we know it is completely done if you freeze credit for 18 months.
Legal actions are currently in the process of being carried out. But this take some time to clarify thinks.

Like part of the pictures come from old failed social networks which sold them and which in their AGB _might_ state that they can do so. Now it's questionable if such AGB is valid at all but as such it needs to:

- If European citizens are affected (it's hard to be be the case).
- the exact legal status as pictures might have been optained legally before GDPR
- ...
- also note Clearview stores biometric data (devices from the images, necessary or "fast" search/lookup would not be implementable

So I would not be surprised that Clearview will be required to delete all data from which it can not be sure it's not from EU citizens, which I think would mean all data given what they store and what they don't store. Obviously they won't comply and a EU wide arrest warrant might follow which is kinda useless if the person doesn't enter the EU. I highly doubt that they will try a international warrant.

So practically it's unlike that anything will change except the operators of Clearview being listed official as "potential" criminal (no arrest => no court => innocent until convicted)
"drivers are gaming the system by not going to work until there is a surge price in effect"

So, immediately after you explain the way that surge pricing works in terms of supply and demand, you claim that one of the parties is being immoral by not supplying the product under a certain price? How is that "profiting at other people's expense"? You literally just explained how it's a win-win. Do you feel like the drivers are morally obligated to supply their time at a certain low price?
The problem is that without User Agent sniffing in some circumstances there is no other way of working round a browser bug e.g. There are cases where browsers will report that it supports such feature using one of the feature checks but the implementation is garbage. The only way is to have a work around based on user-agent sniffing.

Sure a lot of developers abuse the feature but I fear this might create another set of problems.

Note that there are three different things here:

LTE-Advanced rebranded as "5Ge" (only AT&T for now AFAIK)

Low-band NR which is genuinely 5G but only moderately faster than LTE-A (T-Mobile)

High-band (mmwave) NR which is the fastest 5G flavor but it cuts out really easily (Verizon)

Great idea! Why wasn’t this something before.
Agree with the Oura recommendation, and there's a separate reason to be interested in Oura -- it records body temperature, which might be useful in predicting infection.

Here's a project my spouse is working on to see whether it's possible to warn you when you're getting sick using the combination of resting heart rate (from Fitbit), temperature (from Oura) and sleep data:

Corona Calmness: A mini-program to deal with the anxiety to Covid
I thought I'd share something I've been working on for the last 2 weeks to help me and my wife deal with all the anxiety, numbness, and uncertainty we have been facing living here in California.

I put together the best parts that I can find related to Mindfulness and Cognitive Behavior Therapy and put it together into a cohesive mini-program that takes around 15-30 minutes to take.

I made the CBT portion especially focused on issues related to the Coronavirus and the anxiety coming up about health, the economy, job security, and family matters.

The two of us went through it multiple times and it made a difference to us. I've seen a lot of anxiety about this topic on hackernews as well, so I figured I should share here as well.

I'm just a solo maker who's in between jobs and doing only some side work with a company to keep things afloat. I figured I should charge something for it, so priced it at $1.99. If you feel you can't pay that, just type in 50OFF to get it under a dollar if you want and FULLOFF if you want it for free. Relying on the honor system here.

So theories so far are:

- High air pollution in northern Italy

- Second oldest population in the world

- Antibiotics resistance

- Social behavior (hugging, kissing, multi generation households)

- Wrong counting (if SARS-CoV-2 is found, the death is attributed to COVID-19)

Autosleep for Apple Watch has had a significant impact on my life and I always rave about it to friends. I've been able to recognize choices in my daily life that significantly impact my sleep quality and have made changes that have improved my sleep because of it.

I don't know how accurate it is in terms of tracking restless legs unless the movement of your legs causes movement of your upper body that would impact watch acceleration sensors and gyroscope?

Quality sleep seems to have a cascading impact on the rest of life so this app has been hands down the most useful purchase I've ever made in the software category.
I honestly would think HN would be the opposite. The only reason I got rid of my Nexus 5 was that the battery was dying, there isn't really anything compelling enough for me to even consider a new flagship phone.
For your app, maybe.

But most apps cannot be used offline at all, and instead they use localstorage as another place that can store tracking cookie.
So as a user, I fully support this change, because there should not be a loophole like this.
At night time, coming over a hill, coming up to a crosswalk, being met with oncoming headlights, it’s reasonable to expect a little more caution than just driving the speed limit as if it’s broad daylight on a flat road. The report seems to indicate that one person was on the ground and the other was helping them up. This doesn’t sound as completely unavoidable as your example.
Man, I created ScreenTime (https://tryscreentime.com) (yes I'm aware of the name), which at its core, is a virtual camera driver.
