Just the ability to access the rest of the file system I think I wish was on a folder by folder basis.

My text editor for example, I personally wouldn't mind if once per project I had to give it permission to access a project's folder.

I also wish there was a way to edit a file without giving access to the folder. For example Photoshop, I can select from the finder "Open In Photoshop" which is enough intent to give the app permission to access that file without having to give it access to the other files in the same folder.

I get that would require API changes and that Apple doing that overnight would break apps but basically going forward I wish OS makers would work toward something like that.

Even on iPhone I hate that apps either get permission to read all photos or none. Yes I get you can send a photo to an app but many apps can not receive them for every use. I get the apps want to present their own UI for the photos. Maybe some kind of OS run sandboxed process where the app can provide a limited function to present thumbnails but can't actually read any data and all they get out of that process from the OS is the user selected files? Oh well, I can dream.
No, not at all. I quit my job of my own volition, and have several years of living expenses in liquid financial assets. Most people are not that lucky.

Additionally, the two companies that I had narrowed the search down to did not freeze hiring. Pretty lucky, since tons of companies did, although I constrained my search to remote jobs only so that's probably why.

I accepted a job offer and start soon, actually.

That being said, I do think that the general experience of being jobless during this has made me more sympathetic of those that truly lost their jobs than I otherwise would have. Which is not to say that I wouldn't have been sympathetic, I absolutely would have, but the fact that I had to deal with COBRA and other fun artifacts definitely made things a bit more tangible for me.

Excellent point/question.
Deepmind's AI would be ranked in 5800-6000 MMR range by Blizzard if they would actually use the matchmaking instead of random opponents and a ELO calculation formula which wasn't suited for the circumstances nor used by Blizzard. It's actual win-loss ratios against opponents below and above 6000 were: T — 15-4 and 3-8, Z — 15-8 and 3-4, P — 26-1 and 0-3 (which produced whooping 6352 by formula DM used).

The AI Economist: Improving Equality and Productivity with AI-Driven Tax Policy
The day that my work group decided to start working from home, there were roughly a couple thousand reported C19 cases in the US. The conventional wisdom among the people around me was that we stay inside until the game changes, which could happen for a variety of reasons:

* We gain a definitive understanding of how the virus works: Its prevalance, severity, etc., and can adapt our plan based on that information.

* Effective vaccine, treatment, etc.

* Massively scale up testing, tracking, etc., so the spread can be controlled effectively.

Gross Margin = Revenue - Cost of Goods Sold

SaaS usually don't include development costs into COGS. Only directly attributable costs (hosting, customer support, etc.)

Tesla on the other hand has to include raw materials and even labor into COGS.
I’m not really certain where I stand on that, but several thoughts come to mind.

It’s If a bicyclist and a driver approach a four way stop and the driver runs it, he can kill the bicyclist. If the bicyclist runs it, the driver can kill the bicyclist. While the risk is not symmetrical the outcome is the same.

One would think that the party with more risk would be less likely to run the stop sign but in my experience (which is probably not typical world wide) in the Bay Area the opposite is true. Although admittedly it seems the law just isn’t enforced here. Maybe unequal laws would more likely be enforced and some combination of personal risk plus enforcement would achieve the desired outcome.

Additionally many bicyclists are also drivers. So it might be prudent to penalize them for the behavior equally so that it discourages the behavior in general and removes dangerous drivers more easily; assuming their behavior on different vehicles correlates.

Last time I launched a new website it took less than a month for someone to let us know that we'd forgotten to configure a AAAA and our site was inaccessible for them. And that was at new website traffic volume.

So yea, GitHub definitely knows about AAAA records and has intentionally decided not to have one. The question is: why? They must have a reason. Maybe even a good one. I'm curious.

Well, to be fair:

- Google Chat = Hangouts Chat = Google Hangouts Chat
- Google Hangouts Meet = Google Meet
- Google Hangouts = Google Talk = soon to be dead
- Google Allo = dead
- Youtube Messages = is it even a separate product?

So by the end of 2020, the line-up should be like:

- Google Meet (=Zoom)
- Google Chat (=Slack)
- Google Duo (=FaceTime)
- Google Voice (=Phone call)
- Android Messages (=SMS).

Not ideal, but not as bad as you described.
Not sure. My other comment in the thread got hit with a downvote at basically the same time. If there's a constructive discussion to be had, I'd like to have it. If I got something wrong, I'd like to be corrected. But I'm getting the sense that I somehow hit a nerve with the comment above about the strategy not being to just sit and wait, which is interesting. If theres a way to improve the tone of my communication to not generate some reflexive downvotes I'd also like to know that.
Is there evidence of that? I remember him claiming he hadn't left the basement at all. Also, I know you can't tell by looking, but he never really looked all that sick. Never a stuffy or runny nose and usually not that tired looking, no red face, no watery eyes, etc.

I have no reason to doubt his account, unless of course there is evidence that he didn't stay down in the basement that whole time.
I'm in this situation too; in VIC, Australia with 3/5/8 year olds. It's the 3yo who's hardest to deal with by an enormous amount. Given that the situation in Australia is about as under control as it's possible for it to be, I'm quite confident that schools will re-open within six months. And my gut feel is that we as a family would be better off (mentally, emotionally, and quite possibly even educationally) by treating this as a holiday from formal schooling rather than trying to make this work across such varied ages.

At this point it just seems like it's here to stay like the seasonal flu and we're mostly just doing economic harm to ourselves...

Estimation of excess suicides due to Covid-19 lockdowns
We didnt overwhelm hospitals, we have contact teaching apps developed, we have a drug that's likely to be approved tonight or tommorow, and we have multiple vaccines in trials. We should have done a far better job early on, especially with testing, but the biopharma sector has risen to the challenge to move faster than basically every before.
The CDC, US Surgeon General, and WHO have all claimed with a straight face that masks don't protect you from getting the virus. I guess that's why they didn't see any value in stockpiling them. /s

The US beat every single expert pre-peak total deaths prediction; by a lot. There are supply chain issues to fix, and the few spots that could not deal with the case load need to be fixed, but by any scientific measure against the predictions, we did excellent.

https://www.imperial.ac.uk/media/imperial-college/medicine/s...

p16: "In the most effective mitigation strategy examined, which leads to a single, relatively short epidemic (case isolation, household quarantine and social distancing of the elderly), the surge limits for both general ward and ICU beds would be exceeded by at least 8-fold under the more optimistic scenario for critical care requirements that we examined. In addition, even if all patients were able to be treated, we predict there would still be in the order of 250,000 deaths in GB, and 1.1-1.2 million in the US."

EDIT to rrss's comment:

First, note that ~60k is how many people died and tested positive AND were coded as COVID-19. It's not necessairly how many people died because of a COVID-19 infection. We will not know the real #'s until all-cause death is examined. There appears to be a significant drop in "normal" pneumonia deaths for example. It also ignores the error bars on the testing false/positive/negative rates.

Second, I'll restate: The US beat every single explicitly enumerated via a integer expert pre-peak total deaths prediction; by a lot.

If the authors had given a table for the US, we could see what their model predicted, but they did not, and _you_ assuming that the US is a linear relation to GB may or may not be accurate.

i think there is a lot of superiority feeling in Western countries over Asia and then in Western countries against each other. For example when things started happening in Italy
the Germans thought that it's an Italian problem.

As far as the US goes it was pretty clear that the administration didn't want to deal with this at all at home. So they were constantly behind the curve and did things only when basically forced.
> You are not being consistent in your arguments. You are criticizing me for not making an apples to apples comparison and in the same paragraph you are doing exactly that by talking about all the preventive measures that reduce flu deaths while ignoring that the country is currently shutdown to prevent COVID deaths.

Apologies, what I was trying to say is that comparing COVID now to an average flu isn't an apples to apples comparison even if the numbers land where they are now, for all those reasons, some of which are non linear. This is including the ones you mention. The flu has a vaccine, and plenty of past exposures. COVID has the shut-down -- though it also has huge virulence and asymptomatic transmissions that appear to be ongoing.

> You are cherry picking statistics to support your point while ignoring data that conflicts with it. For example the data coming out of New York suggests a higher fatality rate and the numbers you are using from the Diamond Princess are either out of date or flat wrong.

Indeed the Diamond Princess number was out of date. I'm suggesting that there's a broad spectrum of CFR estimates (0.08% to 15%) and there's reasons neither is representative.

> You are both putting words in my mouth and pretending I didn't say things that I did. No one here ever said "this disease is a "death sentence" for an asthmatic 20 year old".

I don’t think Jobs was ever as irresponsible as Elon is. At least not publically.
If the government entity really is throttling that site, assuming they are competent, you're unlikely to find conclusive proof that they're actually throttling. Compare this with a full on blackout (i.e. Great Firewall of China, where that's obvious proof of government intervention); the fact that they're allowing some requests to go thru means that the meddling is likely engineered to not be detectable. Best you can find is maybe the speeds are slower when accessed from within the country, but they can always plausibly deny it.
That's not really the point.

When some (alleged) offense is committed, intent matters. So the question is, when the company came up with those flavors and marketing, who did they have in mind? Do they have Powerpoints showing that middle-aged executives love them, or did they explicitly, knowingly target kids?
I've read a few paper on this subject you are absolutely correct, I don't know why you are have been downvoted.

Vitamin D is only produced with in UVB wavelength [1]. No vitamin D is produced over 318nm. I wonder if that's the reason they divided the range in UVA, UVB and UVC.

The solar ray incidation angle, pollution and altitude (higher, more UVB) affects the amount of UVB that hits the surface [2].

Therefore, the time of the day you are sunbathing is important to optimize Vitamin D synthesis. Midday is the best time. If you live bellow 25 degree latitude, the UVA/UVB ratio on winter is about the same on summer. Of course, you should take in consideration the weather and the UV index. I'm talking only about the ratio.

This paper [3] has guideline for sun exposure for Australian. It is possible to correlate the data for other places in the same latitude -- taking in consideration the Australian differences in UV index.

Coronavirus 'As Deadly as Ebola in Hospital'
There used to be a time when you could actually tell your phone whether you wanted to use biometrics or a passcode. You could either place your finger on the home button for Touch ID or use “slide to unlock” and go straight to the passcode prompt.

Then an idiot at Apple decided it was too complicated and you now need to wait for biometrics to fail before you can type your passcode (also, biometrics interfere with passcode entry and will erase any entered digits).

How about they just bring back the option for the user to tell the device in advance which auth method they’d like to use? There are a lot of other cases not related to masks where you know in advance that biometrics are going to fail and would like to not have to wait for them to fail before entering your passcode.
So interesting, so even with inaccurate tests so long as we're dealing with reliable metrics backing those tests up then the degree of actual accuracy that intersects with the nominal accuracy is enough to carry out the compounding with and effect targeted quarantines with. Probability products stack up quick. Hope that makes some bit of sense.
Nice idea. But I always wonder where it started that pricing is a thing to be hidden.
What does your service cost and why can’t you be open and transparent about this? Not finding the pricing info turned me away instantly.

Show HN: LightningNDA, a free tool to quickly execute NDAs
I had a loaner machine (RS-6000 minicomputer) that would have unrecoverable ECC errors when the cover was on. The tech would come and try to diagnose it, but with the cover off, everything would work fine. He'd swap the memory anyway and put the cover back on. within a few hours the memory bank would be failing again. Turned out the machine had been a loaner in a lab where it had acquired some alpha-emitting goo on the inside of the side panel. The lab had just run it with the side panel off to solve the problem, never noticing the goo, never mentioning it to IBM when they packed it up to ship.

It's a long story but the gist is after multiple board swaps, realizing we'd isolated the panel as the fault, I noticed the goo and on a hunch checked it with a scintillator, deducing it was alpha when cardboard blocked it. Turns out the ultra-precious-metal IBM heat sink on the board had an open path that effectively channeled the alpha particles into one of those multi-chip carrier thingies, which featured exposed chips.

As for why I had a scintillator lounging in my desk at a portfolio management company, don't ask. Let's just note the iconic IT anti-hero of that era was the Bastard Operator From Hell, and leave it at that.

> For example when things started happening in Italy

As someone who lived in Italy and now lives in the US, this was driving me absolutely crazy. They have a great health care system, and are a transparent democracy. When things started to happen rapidly there, it was very, very clear that the same situation would play out in the US, and yet there were still a lot of "just a flu" people.
The WHO and Chinese telling people in mid January that it wasn’t person-to-person transmissible should probably take some serious blame. Taiwan warned the WHO on Dec 31, and the WHO ignored them. The WHO and Chinese obfuscation and downright deceit should not be ignored. The Taiwanese know better.

Of course, there is also the question of Sweden..

Wollay and most software development he does is intermittent at best. The Cube World community went 6 years without an update. He will occasionally (every few years) post screenshots and teasers on social media, but it seems very clear that development of his projects is whimsical. I don't think anyone at this point would be surprised if he tweeted out tomorrow that he's done developing Cube World.

It also seems that Plasma was never actually sold. It was a preview that just required a free signup.
Sure, but I doubt you stop at green lights even though someone might run a red light. Next time you drive, notice how many gambles you make despite how defensive you think you are. Hell, a single trip down a 60mph two-way street with only a yellow paint divider has probably exposed you to more risk than all of the mortal danger your defensive driving has saved you. I just think it's a weird line of inquisition to wonder why someone wasn't more defensive when hit by someone else.

Remember, only three cyclists have died at this intersection over the last six years while being a popular bike route. Not every cyclist is getting eliminated here. But it doesn't take many deaths to make you go "hmm, how can we design this intersection better?"

My point is that the answer to "why don't cyclists look to see if a car is running through the yield?" is probably "most of them do". That's why there were only three deaths in six years. It's a weird question to ask because even though you could scold those three people for not driving more defensively, the signage could simply be improved (and it was).

I doubt the compiler would optimize out multiplications like that, as floating point math is not necessarily associative. You'd have to pass -ffast-math to get the compiler to attempt to optimize that out. It looks like typical compiler output to me.
