But it's not the only driver, so it's not necessary. Perhaps it's the strongest motivator, but I look for improvements in many things, often they're systems I don't use or products I'll never be able to afford. It's not disappointment that drives that (arguably it might be historic disappointment).
On Ubuntu would installing Zoom via Snap be preferable than as a normal package when it comes to security / sandboxing?
I suggest you:
A) Take a look at the price difference between the phones you just said, and re-read my original point.
B) Don't cherry-pick a phone. Try this one from your same reviewer:

A manual switch is still an attack vector, and I'd bet one of the lightswitches in your home has already been "compromised" where you have to wiggle it a bit to activate it.
We need experts.

But we also need to use our brain.

Even when trying to use my brain, I have troubles understanding how droplets can distinguish the direction of passing through a face mask, i.e., how my face mask can help protect others from my droplets, but how it cannot protect me from other people's droplets.

Well, I do understand that if the holes are too large, it will not be a 100% protection, but I do not really understand how the direction would matter.

That said, preventing a run on masks is important if you don't have enough, because some people need masks more urgently than others. I am convinved that in order to prevent a run on masks, you cannot just tell people the truth, but you need to lie to them, because many (or most) people will still get a mask if they know it is actually somewhat helpful.

The USDA definitions are extraordinarily misleading. “Food insecure” includes people who are at no risk of going hungry, but wish they had better food or a larger variety of food.
I'm not trying to argue about whether hand washing is important. I'm trying to increase my understanding of the transmission, and I hadn't heard before that touch face/nose/mouth is the primary way of the disease spreading as you stated. As you had said earlier in the thread: "Please stop spreading misinformation as it could lead to deaths". If you have a source for stating it is the primary method of transmission, I'd still like to see it. Otherwise, perhaps don't repeat that claim, in the interest of not spreading misinformation.

Here's the best article I've found on transmission, and a key excerpt.
http://www.cidrap.umn.edu/news-perspective/2020/03/commentar...

> In risk communication guidelines for healthcare, however, the WHO states, "COVID-19 appears to spread most easily through close contact with an infected person. When someone who has COVID-19 coughs or sneezes, small droplets are released and, if you are too close, you can breathe in the virus" (emphasis added).9 But wait: Inhalation is not part of the traditional definition of droplet transmission.

> For healthcare organizations, the CDC recommends airborne, in addition to standard (contact) and droplet precautions, for the care of COVID-19 suspected or confirmed patients.10

> For the general public, the CDC describes SARS-CoV-2 transmission as primarily by droplets from coughs or sneezes, which "land in the mouths or noses of people who are nearby or possibly inhaled into the lungs" (emphasis added).11 But, again, inhalation is a new addition to the traditional definition of droplets. In contrast to its recommendations for healthcare, the CDC makes no mention of airborne transmission in public settings.

> The CDC admits some possibility that COVID-19 may be transferred by hands to mouth, nose, or eyes from contaminated surfaces, but notes that "this is not thought to be the main way the virus spreads."11
They can still write software to insert themselves into the key exchange flow and eavesdrop on a conversation. E.g. I don’t believe there is anything stopping Apple from pretending a participant bought a new device.
There are also reports of people being completely asymptomatic throughout the entire infection. And of people being contagious after all symptoms have ceased.
As a follow up, suppose I don't become current for many years and my TN Visa expires. Would I be able to keep renewing EAD/AP every year in order to keep working in the US until my I-485 is processed?
12 months is a long time to line up another job. Announcing the same day, or even the same week, will cause a good deal of disruption. I've survived layoffs of a much smaller scale, and can confirm that productivity goes way down once word gets out until the process is completed.
Hi Peter, thanks for doing this!

I just got H1B lottery. The company is promising that they would apply for the green card as soon as I'm in US. My question is: is that possible for them to do that, generally and given the current scenario?
No source, but there’s just been such a long history of side channel attacks, and similar research (https://nofilmschool.com/2014/08/mit-extract-sound-audio-sil...) that it makes one wonder if a non-hardware disconnect fix is sufficient.
I ran into someone with a finance degree who couldn't believe $0.01 doubled for thirty days wound up being over $5M. I had to show them an Excel spreadsheet of each day.

It's literally just all (or close to all?) existing public school cafeterias staying open.

Same cafeteria workers as always, same types of menus.

The biggest change in logistics seems to be that all the meals are now to-go, so goodbye trays, hello bags.
Hot take: You need a food equivalent of Medicare, where you can walk into the equivalent of a public good supermarket (Aldi would be my example, perhaps adjacent to a library and community center, with a "dine in" meal area), and walk out only with healthy foods or a healthy meal. Regarding food deserts, you need to force the distribution chain where it isn't, even if it isn't profitable (we don't look at the profitability of school lunches, soup kitchens, or food banks, for example).

Citizens also need help understanding nutrition and health diets (existing efforts are woefully inadequate), and direct cash benefits (SNAP) are suboptimal for that, considering food industry marketing efforts (looking at you Coca Cola).
I've even heard of a study that showed that stress is only bad for you if you believe that stress is bad for you.

That's an interesting one to ponder, isn't it?

But if I'm an average user and my phone is slow, my first thought isn't "hey I should get the battery replaced". It's perfectly reasonable to assume the phone would still be slow, so why not just buy a newer model?

It's a lie of omission, which you could reasonably interpret as a trick to get people to upgrade.
Yeah, gotta say that the NASASpaceflight forum does a better job of keeping on top of Starship-related things and being organized than the Reddit site.

Our town went into lockdown. I talked with Craig, a homeless guy I see occasionally. He said first day, kind young people came by with gloves, vitamin C tablets, some kind of facemask. After that - nothing. Its been weeks now.

Charitable organizations can run down once the volunteers have done enough to feel helpful. Not a good thing to rely upon, not in our modern society.
DoE is uniquely suited to preparing and serving large numbers of meals.
It sounds like in that case there was clarity about who was being laid off, as well as plenty of advance notice.

I think people are objecting to announcing "Layoffs are coming" and then having to wait some period of time to find out who is included.

The timing is also important, what's being discussed isn't "in 12 months" but immediately given the quick turn in cash flow for many of these companies due to a big external event.
It says here he was awarded $75,000, instead of the $150,000 listed on the Apple page for this type of exploit. Later on, Apple specifies:

> Reports that include a basic proof of concept instead of a working exploit are eligible to receive no more than 50% of the maximum payout amount.

Can someone explain to me what would have counted as a “working exploit” here vs. simple proof of concept? They can’t mean actually finding it in the wild right? The OP’s example seems working enough to me, and this looks like a really bad bug.
One thing in this study I find totally surprising is this: how can aerosol from different virus classes be differently contagious when passing through a mask? They seemed to have measured that, but it would really be very interesting to get an explanation how this is possible. How does a mask filter the contagion from corona aerosol, but not from rhino aerosol. This is totally perplexing to me.
Good points. Plus the demand for tech is higher than ever due to the productivity advantage. There are pockets of that common-good advantage being demonstrated here and there, so maybe that can be patternized and better demonstrated to the whole. I'm sure there are immediately applicable ways to redirect a lot of the waste.
In Chicago the schools are still handing out lunches to parents/kids to come and pick up.
It's important that there isn't a gene that controls the eye colour.

Eye colour is modulated by several genes which haven't necessarily been identified - I understand this to be an open question.

I can give an example, though:

Eye colour is a function of what pigments are present in the iris, the most relevant pigment (in humans) being melanin, which also contributes to dark skin and tanning.

So, melanin is produced via the biochemical pathway 'melanogenesis'.

Among other things, the process of melanogenesis requires the enzyme tyrosinase, a protein which has a decent length wikipedia page.

If you are missing the TYR gene which codes for the protein tyrosinase, then you will likely be albino. This won't only affect your eyes, then.

I say you will 'likely' be albino only because it's hypothetically possible that a lack of tyrosinase could be compensated for with another biochemical pathway. And, of course, albinism could come about by some other break in melanin production.
Would also be nice to have little hardware LEDs that automatically turn on when the microphone or camera are connected. That way you are sure to know if they are recording.
Perhaps as that was based on random internet comments. FaceTime still ends up at level 2 with Zoom and the rest because Apple can MITM the traffic without much trouble. There is no provision for the user to prevent/detect a MITM attack in FaceTime or iMessage.
There is a french saying I first heard back during the 2008 crisis: "It's urgent to wait".

I liked it, consicously waiting might be exaclty what one should do now. Don't rush, wait, and move once you have to.

Like the line in the movie "Shooter": "Slow is precise and precise is fast". Just rushing things now because of reasons can do more demage than good.

All of these databases have geospatial data types for efficient querying and indexing. It's been a standard feature for years.

Even if they didn't, there are plenty of algorithms based on lat/lon which uses numeric/float data types with simple indexes.
Would a Rust spec that actually allows multiple compatible implementations actually be simpler than the C++ spec? There has only ever been one real Rust implementation, and a lot of Rust behaviors are just arbitrary implementation decisions, especially with subtyping in the type system and the borrow checker.
The destruction of AirBnB may push rents down. Hard to see how rent can go up beyond what people can actually afford?
Because this is primarily designed for kids who were getting their breakfast and lunch for free at school. Them not having food was one of the top problems cited with closing schools.

So basically you can still get your meals for free at school, only now it's open to everyone.
After the lockdown is lifted, do you think the fast food chains will allow for this to continue? How much of this could potentially eat into their revenues?
No, placebos don't work.

That is not what is meant by "the placebo effect" by doctors. There is no active ingredient in a placebo. That's why it has no effect on broken bones or cancer. A placebo doesn't have an effect on anything.

However, patients that receive treatment that include a placebo medication and/or procedure (instead of the active version) often report improvement in their perception of their condition. Including pain, nausea, depression, and anxiety. The patients report feeling better.

This "feeling better" after receiving a fake treatment is the placebo effect.

The reason a kiss and a hug works so well on kids (and adults) is that it is comforting and loving. It makes them feel safe and secure and cared for, lowering their anxiety and indeed pain.
Hi Pete - which countries do you think have the most positive immigration processes/criteria, and why?
I see a lot of Lisp stuff on HN : do a lot of people use it ?
There are no immigration issues with working outside and within the U.S., as long as your home is within the MSA/normal commuting distance of the work site noted on the LCA, there are no issues. The challenge arises if your home is outside the MSA. Currently, this requires the filing of an amended H-1B petition but it's possible that USCIS will relax this rule.

I have two questions in regards to OPT for F-1 visa holders:

(1) What is your best guess what the changes that ICE announced to OPT is going to be? (see here https://www.reginfo.gov/public/do/eAgendaViewRule?pubId=2019...)

(2) What is your best guess what the outcome of the WashTech suit against OPT is going to be? (see here https://www.nafsa.org/professional-resources/browse-by-inter...)
If OPT falls would such a change be effecting all current F-1 holders?
To expand on this, apps could also (ab)use "overscan" modes, which granted slightly larger resolution but image quality at the corner/borders was often somewhat unreliable.
There's also the small matter of us valuing ourselves rather highly regardless of whether there's a million others like us that could equally create more wealth for which ever capitalist we'd have the misfortune of being owned by.

I'd argue that what you're saying is true, in its current state. High-level Rust libraries take longer to write, and so they don't exist yet. As soon as Rust gets more powerful tools that abstract away the work, I suppose it might alleviate a large part of the churn.
I read it to be saying it's 'done' in the sense that their documentation is now in a good state, and so doesn't need special attention. Not to say documentation is exactly 'done', of course.

I found the post a bit unclear, but my interpretation was that they're officially ending the 'Rust docs team', and will be reducing their focus on documentation, maintaining it in a more ad-hoc way.
I think obesity dis-proportionally affects impoverished African Americans vs. other impoverished races.

At least based on one point of anecdata - my neighbors. I have lots of poor families in my neighborhood even though I am middle class myself thanks to HOC (a Maryland social program where middle class housing is subsidized for the poor). Long story short - my poor African American neighbors are extremely obese; and it's no wonder why. I only ever see them eating McDonald's/dollar tree chips/soda. I know they are on SNAP, but I don't know if they are trading it for booze/cigarettes. It's my opinion though that they lack education on how to prepare/cook cheap raw ingredients into meals.

Yet my other equally poor immigrant El Salvadorian neighbors are skinny as rails and from what I can tell they eat tons of rice and beans and such (I often see them carrying 20 lb bags of rice into their house).
So they're using the closed schools with their commercial kitchens to do this. Interesting.

At first I was hoping that they had partnered with restaurants, but this is pretty cool too.

The cost of the program is not a very good way of evaluating it. the number of people it feeds and how well it does so would be a much better criterion.
That schedule change wasn't related to a schedule slip on starship, it was a decision to switch from a small mission (by number of people) using a falcon heavy and crew dragon to a bigger mission using starship.

It might have been related to the schedule slippage on crew dragon though, considering they are just now ready to fly astronauts on crew dragon.
H-1B petitions are still being processed since there's no labor market test associated with these but PERM-based green card applications could be put on hold because a labor market test is central to this process and layoffs by the sponsoring employer can result in the end of this process.

That's exactly the point: new medicines are tested against a placebo rather than against no treatment at all, because the placebo does have an effect: the placebo effect. It is an effect, and it can be leveraged to make people feel better. Is that quackery? Or is that making people feel better?
Sounds like a situation I've found myself in before. The majority of the work is done, and it's become more work to organize and maintain a team than to simply do it on your own.
