Here's my perception of the markets for the MBA and MBP based of anecdotal observations:

The MBA is for students, the sales force, and road warriors. These people value ultra portability and long batter life and typically don't have highly demanding use cases necessitating a lot of processing power and storage.

The MBP is geared toward the so-called power user who needs portability. That portability is typically moving between meetings or between facilities where they work. They're generally always close to a power source.

This has been my observation since the MBA was first introduced. I'd love to see Apples' product personas to see how close my experience is to their expectations.

So buyer beware does not apply to housing? In case you buy the wrong thing or in the wrong place or the wrong time you just get reimbursed?
HK/Singapore/Japan numbers also don't seem too bad either[0]. Seems their responses have been pretty good? SK's numbers are higher (last I checked), but I know they had the issue with those religous gatherings hampering their containment efforts.

> People not having jobs means they could end up homeless and vulnerable.

Eviction/foreclosure bans have in many places been adopted along with shelter-in-place orders.

Why California’s emergency approach includes the power to seize hotels to rapidly expand shelter capacity (and why SF is in negotiations to buy hotel space for an extended time for that purpose.)
I took tests in the 1600 era. I came from one of the best public high schools in California. I would say 80%+ of the high school had SAT prep, every single one of the people I talked to at school had SAT prep.

If you're not including self study, then maybe? But with prep and self study, everyone I knew was able to get at least a 100 point increase, I think I got a 300 point increase. Basically aced the math section through practice and study (missed 1 question).

There was a speculation I saw on Twitter, apparently considered by some serious people, that COVID-19 already swept through Seattle a couple months ago and was thought to merely be a bad flu season. I personally think this seems rather unlikely, but with an antibody test we could start to check people who had this mysterious flu.

> You don't need to be a rocket scientist to learn about and understand data egress costs. Which left The Register wondering how an agency capable of sending stuff into orbit or making marvelously long-lived Mars rovers could also make such a dumb mistake.

I used to work very closely with this department at NASA. Without saying too much, the short answer is "tenured government employees more concerned about job security than the success of the project" is how an agency could make such dumb mistakes.
Ask HN: What Evidence Exists That Covid Is Not a Scam?
It is starting to seem like a over-hyped issue. There's not enough deaths to justify this in comparison to the many other much more dangerous diseases.

There are multiple vaccines available.

Many of the earlier countries have basically recovered.

In the US, however, the politicians and the media have murdered the economy and enacted extremely draconian measures in response.

This just seems like a giant scam - convince me otherwise.

I'm curious about that aggregate and a bit scared by the different ORDER BYs, it looks like you the function would be unable to re-use index reads for other column values.

Do you have much experience with Postgres WINDOW[1] expressions? That might be a useful tool for you even if it takes a bit of time to fully grok it. I don't use WINDOW often but one place I found it was insanely useful was for supplying a tabular page with aggregate data points outside of the data currently being paged to the client - we have a query that returns row information in a paged manner but the query driving it both narrows the row scope to fit the page size request while also using WINDOW functions over the un-partitioned data to calculate a few business useful averages.

This is a method used to cash out stolen credit cards as well. Buy the item with a stolen card and ship to the unwitting purchaser. This is why they can afford to sell at a perceived loss.

It's hard enough such that schools have to lower their SAT standards to accept underrepresented minorities.

Otherwise, for non-URMs, the top schools do agree with you. SAT (and school GPA) are usually used in threshold-y way with other factors mattering more.

The SAT subject tests just felt like a joke to me anyways. My high school was a public high school in Singapore, a country generally considered to have great education. With a generally good mastery of the normal high school curriculum, these tests were considered very easy. Pretty much all my friends and I got 800 out of 800 for all the subject tests. And these perfect scores ended up not mattering that much in college admissions anyways.

The normal SAT I tests, on the other hand, seemed to require more critical thinking, higher reading comprehension and reasoning skills, skills that are sorely needed in an age of blatant misinformation. These are much harder to score well, which is why so many people spend a lot studying for them. Not so much for the SAT subject tests.
There were 99/204 cases where a gastrointestinal symptom was present, though 92 of those also had a respiratory symptom. 83/99 of those with gastrointestinal symptoms complained of a "loss of appetite." 4 complained of stomach pain.

"Lack of appetite" is another symptom to watch out for, a stomach ache or diarrhea without respiratory problems shouldn't cause much alarm.

How does Forbes's print that without mentioning "a lack of appetite" once?

I'm not very surprised, most of the travel industry is getting hit hard. On a side note, I had a very bad experience with Airbnb. I found out, because it happened to me, that they remove negative reviews of hosts. I lot of the rating on their site are goosed.
I think the spirit of the post is correct: the quality of instructors can dramatically increase the quality and relevance of course content in the curriculum. Stanford courses tend to produce new, interesting assignments that other schools crib. Same applies to all the top engineering departments.

My friend tried to get a CS degree at Pepperdine and the curriculum was 15 years out of date. To students who are new to the field, it is hard to figure out where to start even if they could do it independently.

It's interesting contrast to read Krugman's piece in the nytimes just yesterday.

He ignores the "economy", he says that layoffs are necessary, which is to basically suggest that the economy will adapt.

And everywhere you have internet commenters "But what about the economy?" and citing serious consequences of recession/depression in order to criticize isolation/quarantine/lockdown.
Ask HN: Smartphone app that tracks coronavirus risk from past contacts?
A smartphone application that gives each user an identity (like an email address, or one specific to the app) and shares their identity with people in close proximity. Distance is estimated through signal strength or something.

The ad-hoc communications would be similar to the AirDrop system that can transfer files between nearby Apple devices when enabled.

History of contacts would be tracked. If someone is infected with coronavirus, they can tell the app this, and it would send a message to everyone with recent contact with the person, based on an estimate of time of infection and how long they have been contagious.

Is there an app that can do this already? Is anyone working on one? Should it be developed, if it hasn't already?

Of course it wouldn't help for people who are too poor to have a smartphone, like me, but most people do have one. It also wouldn't help much to p̶r̶e̶v̶e̶n̶t̶ predict (prevention is from early self-isolation or treatment) infection from someone who has already left the vicinity, unless there was a (much more involved and centralized) process of tracking physical locations, possibly including moving public transport.

Since in many cases, adjusting texture resolution (in the case of under-sampled textures), or removing items from the scene or from being rendered (in the case of items being entirely obscured) can dramatically affect a game's performance without changing at all "what you want the game to look like" So clearly that phrase isn't sufficient to describe the action being taken.

Citing coronavirus, homeless families seize 12 vacant homes in L.A
That’s true. Though you could still buffer it with a “must be positive for N weeks” rule.

Also, while there would be concern about a positive but still shedding person coming into contact with one who hasn’t contracted it, there’d be no issue with them hanging out/working/etc with others who are positive.
> And those expensive prep courses had the potential to increase scores over 100 points.

As compared with self-studying with free online practice tests and resources having the potential to increase scores over 100 points.
maybe for low-level engineering drones who don't have any say in what gets built, which is typical for the first few years of an engineer's career. But senior engineers, and especially engineering management need to have good communications skills to work cross-functionally.

He got around 28 knees there, I’d say."

This is outright disgusting. I'm glad these kind of brutal policies are exposed and talked about.
My wife is a health care provider in Seattle (meaning that our family has much higher than average exposure risk) and the last few months have been brutal. We've all been sick one way or another since January and have had all the common Covid symptoms. So I wouldn't be the least bit surprised if a test showed I've already had it.
Personal use.

I ordered it weeks ago purely as a hypothetical. If I was home sick with a flu, was it seasonal or was it nCov? This was before all the lockdowns started.

I also bought a fingertip pulse oximeter for the same reason. I’m surprised those haven’t been hoarded...yet.
We are looking just at the trend. And the testing methodology that different states take is just a multiplicative constant of the confirmed test. And exponentially growing function will make it negligible.

I think rather than strong what we’d expect is resilient. It’s why people are joking about businesses eating less avocado toast. The advice given to a lot of people in financial hardship is often well meaning but unhelpful. Why didn’t you have three months cost of living saved? Why do you buy frivolous things? Etc. then when it’s business expected to take a few months off suddenly these ideals are no longer important. Why do profitable companies have no ‘rainy day fund’? How is an economy ‘strong’ if it is not resilient to disruption?

What we’re learning globally to a greater or lesser extent is that our economies are not resilient. That capitalism of various kinds has failed us. And that when it comes down to it we need one another to give a shit about each other.
Agreed. I can’t think of the last time I had to use FTP.
The day I lost respect for Lennart Poettering, was when a user reported a bug[0] that starting pulseaudio (which he authored) gave a vulgar error message and his response was simply "Sorry, but please don't waste my time, will you?"[1].

It wasn't as if the user was doing anything exotic, just opening it:

$ pulseaudio
W: main.c: D-Bus name org.pulseaudio.Server already taken. Weird shit!

In the end Ubuntu carried a patch specifically to remove it. I thought it was a real shame he thought that it was both appropriate to do in the first place, and acceptable to be that dismissive to a polite bug report.

Doesn't surprise me he later won a Pwnie award[2] for his bad handling of bugs, specifically security. I'd recommend giving them a read!
