The good thing is that I doubt the factories working on either are readily interchangeable. Lab equipment companies are not going to turn out masks en masse on short notice, nor would textile companies start turning out test kits.

I think arrow functions are less clear because they are always anonymous functions. Anonymous functions complicate stack traces and performance profiles.
AirBnB essentially just copied Couchsurfing and added money to it, pretending it was a new innovative "disruptive" idea (although the platform has since evolved a bit).

There's nothing wrong with that, of course. I just dislike all their Jobs-esque bullshit about it, pretending they single-handedly "innovated" the platform, which they didn't.
If you had a plane with 200 passengers and two machines at the gate, this would take an additional 25 minutes to board the flight to test everyone, assuming there is no prep, which I’m sure there is. So realistically probably an hour.

It seems like a great idea in theory, but in practice? I’m not so sure.

Considering you can have the disease and present no symptoms but be contagious, you’d have to test everyone. I guess it is better than nothing in some cases.

Do these faster and faster tests all use the same reagent that has been in short supply? And has there been any progress on producing it faster, or using less of it for an accurate test?
I can't live a month or two in a hotel, it is just too expensive, while I have done it with AirBnB.

And the last time it was a great place, a bit better than a hotel.
>Perhaps you all stay only in 5 star hotels?

this has gotta be the answer. I have the exact same experiences and feelings as you. I always look for basically the cheapest Airbnb and it ends up cheaper by 2-3x than local hotels and I've never had an uncomfortable stay. What I have had are completely normal rooms in working class homes - which is fine because who the hell cares about enjoying the hotel room when you travel!

If you want to learn about the proto-history of the computer, a graphic novel called "The Thrilling Adventures Of Lovelace And Babbage" is well worth your time.

The comic itself is pure fiction of a zany cartoon comedy variety.

The writer is obsessed with the actual history, though, to a point where her footnotes sometimes take as much space on the page as comic panels.

It's a glorious thing and provides more insight into who Babbage and Lovelace really were than anything else I've personally read.

It always struck me about JavaScript, that if you were going to choose one variable and one variable only to be dynamically scoped (for whatever strange reason), "this" would be the absolute worst one to choose that you possibly could, an automatic nuclear foot-gun that would trip you up every time. If you ever wanted a function to lexically close over a variable, but could choose only one, "this" would be it!

Fat arrow functions struck me like one of those half-assed solutions Trump (edit: or Obama) comes up with for a terrible problem of his own creation, a foolish mistake that nobody in their right mind would have ever made in the first place. And then he expects praise for his solution, and nobody remembers he caused the problem it was supposed to solve in the first place.

I agree with the sibling comment by austincheney:
JavaScript would have been a much simpler and less bug-prone language if not for "this" being dynamically scoped and magical, which later required nailing fat arrow functions onto the side, that were almost but not quite entirely unlike functions.

Have you ever tried explaining why there are two different kinds of functions in JavaScript to a beginning programmer, and seen their eyes glaze over when you digressed into the nuances of "this", lexical scoping, dynamic scoping, call and apply, closures, and binding functions? You have to understand all that before you truly understand functions in JavaScript, and much of it is irrelevant crap.

Lexical, dynamic, both, or neither? Pick a lane, JavaScript!
I use prettier religiously. Works on js, typescript, jsx, css, json, html, sass, yaml and a whole bunch of others.

The vscode prettier plugin brings format on save and it makes coding a joy.

I think what prettier does is much simpler than dart. It tries to put things on a single line if it’s within line length, if it can’t then it uses multi line where each item is in its own line with ending bracket at same indentation level. For arrays, functions, object definitions, jsx etc. I’ve written some automated code generators that output pretty code and that’s how I tend to approach it too. You either get compact or expanded version and that happens recursively. There is some backtracking but there’s early exits when compact strategy exceeds line length so it’s pretty fast.

After reading the blog article it put me off that starting and closing brackets were not at same indent level. I know lispers do this but I’m not used to it so it hurts my brain.

One of my interview questions is to pretty print json files to a certain line length.

> But, I don’t know what the benefit of a 15 minute test is.

At the risk of sounding snarky... Really? You can't think of any way in which a 5-15 min result is more valuable than a multi-hour/day result? We have governors setting up roadblocks at state borders to turn away out-of-state license plates; a quick test seems like it might help there. Then think about what that means for international flights.
The biggest plus AirBnB tends to give over hotels is having your own kitchen, and not having to rely on restaurants. In my experience many hotels are essentially just a room with a bed and some uncomfortable furniture; not a great place to be for a week IMHO.
Also technical translations. There are probably lots of opportunities for translating English documentation to Mandarin right now.

>While I'm ranting, why do they let basements or single floors of a shared house count as an 'entire place'? It's really weird to turn up and see you're actually in a basement in the owners house with their kids stomping around upstairs.

Agreed, this is very annoying. Basement apartments shouldn't show up under "entire place". They may be called basement apartments, but it's just a basement with a family upstairs and almost always constant, barely muffled noise. Some listings won't even disclose this until the very bottom of the description, or sometimes not at all, and then I have to dig through reviews to see if anyone has remarked that it's actually a basement.

I've stayed in a lot of Airbnbs, and every basement apartment has been awful in a lot of different ways. Some are even more expensive than full apartments despite same area and similar quality and size. But if you're on a tight budget, the cheapest option between a hostel and hotel room or apartment probably is a basement apartment, so I suppose they're not entirely useless.

I once accidentally entered the wrong checkout day when booking a hotel (one day too many); I immediately emailed and phoned them within minutes: they could not change the date, and had to pay one day extra.

> First, there's nothing wrong with that.

Sure, you can technically run .app from most places. It becomes problematic in that you can't write to that directory or self update the app if it's still in the DMG. If you reboot you have to know to remount before launching. Not having it in /Applications also becomes a mess if you're in a multi-user environment.

> Also, some apps display a message asking to be moved to /Applications when launched from a DMG.

This is the kind of friction and extra dialog boxes I'm sure they were avoiding.

Personally, I hate pkg files. I wish macOS had a better flow for unsavvy users to deal with DMG and app files.
Having just used it, it feels like a few factors:

- a background scene is usually static. if a pixel matches its historical average (i e. not changing) then it's probably background.

- if a pixel color matches its neighbors, it's probably the same as them. i noticed my black shirt tripped it up on occasion, but was all-or-nothing.

- people are blobs, not diffuse, so try to segment large regions.

Does this work with apps that do their own TLS using their own pinned certs? I don't see how it could. Surely that's a lot of high profile apps these days.

If this app works without root, it must be possible to apps on iPhone to add their own certificates to the system, which are then trusted by other applications - that would already be pretty alarming. I think Android still requires certificates to be manually imported by the user. Maybe this app points you to instructions on how to do this, but the description makes it sound very automatic.

That's a religious justification for noble birth.

No. (See: Chinese Mandate of Heaven; the multiple examples of people claiming to be ordained by gods and similar higher powers historically despite no or little connection to nobility, so on.)

The system it backs up is heritable monarchy, it didn't precede it.

Assuming this is true (which seems highly dubious), what are you contesting? Their claim is that God ordained their rulership, not that 'local religious authorities' did. Regardless of existence of the entity in question, "the primary legitimate basis for power would be noble birth instead of ordination by God" is the right thing to say.

No, what passed was a one-time payment. Due to the Senate recess it was pass their bill, unmodified, or pass nothing at all.

There is some general talk in the house (in particular on the left) that this isn't really enough to handle what is shaping up to be a 4-6 month crisis at absolute minimum and we should do additional payments in the future but that's not what passed, and it's unclear whether the Senate has any willingness to pass anything further.

The Senate took off from DC for a month so nothing will be done before they get back. On this or any other coronavirus-related legislation.

>Guido: Language Design Is Not Just Solving Puzzles

>And there's the rub: there's no way to make a Rube Goldberg language feature appear simple. Features of a programming language, whether syntactic or semantic, are all part of the language's user interface. And a user interface can handle only so much complexity or it becomes unusable.

>The discussion is about multi-statement lambdas, but I don't want to discuss this specific issue. What's more interesting is the discussion of language as a user interface (an interface to what, you might ask), the underlying assumption that languages have character (e.g., Pythonicity), and the integrated view of semantics and syntax of language constructs when thinking about language usability.

Who's Freezing Hiring from Coronavirus
My elderly neighbor went to the ER complaining of shortness of breath and chest pain. They wouldn't do any heart tests until they got back the result of a covid test. They kept him for 5 days without treatment. After 5 days the test came back negative. A 15 minute test sounds good to me if it can be done on site and not shipped away for analysis.
There are people who work in very essential roles (think power plants) who are already facing challenges with COVID right now. Ive heard a few stories about folks at plants where they've divided up teams in ways to prevent groups from mixing (to reduce the spread) and every time someones goes on or off shift fills out a sympton questionnaire and takes a temperature. This in addition to setting up to have people live on site. Having a ten minute test would help a ton in this area.

I've noticed this in the EU/US divide. Anything pessimistic in Europe is deemed smart and cool, and Americans are looked upon as native as dumb for their general optimism.

"Counting seconds" may mean little to you but by proxy you can look at conversion statistics for web stores vs response time and see a pretty clear correlation

VSCode's 'performance' is the result of an obscene amount of tuning the base framework, far more than most applications would need. Most other Electron apps do not see anywhere near this level of optimization (and they desperately need it).

MBP batteries on a new machine are respectable. Like all li-ion batteries they decay with use

Mac OS apps behave very consistently when they are native. True, Apple's user interface guidelines allow for pretty wide latitude in some areas (like skeumorphism) but all the basic OS/interaction contracts are intact. One can expect menus to behave the same way, file open/save dialogs to behave the same way, and so on.

I actually help run clinical trials and regularly advise on clinical trial read-outs, and I can assure you that I could be fooled by a sophisticated scam if I didn't have a governmental entity that can and will actually do inspections and their own investigations with the power of criminal penalty. I think your confidence is entirely misplaced.

But I think that within a decade or so the reality is that we will have more advanced robots (combined with warehouses designed for automation) that can do most of these jobs, including driving and delivery. Not saying it isn't incredibly challenging or that we are anywhere close, but there is progress and also massive, massive financial incentive.

At some point UBI will be the obvious option to everyone. It seems obvious to me that income should not start at absolute zero even now.
I'd say a first step is to start building a body of writing samples. You can do this in a lot of different ways, but two suggestions are 1. adding or improving documentation for an open source project and 2. writing technical blog posts/articles/how-tos on topics that interest you and posting them on a personal website. Starting to build this body of work can also help you discern whether you even like technical writing. Then, I'd say the next step is to just start applying to technical writing jobs. (Maybe contract ones, if you'd like to just try it out first.) Since you have coding experience, I'd suggest targeting tech writing jobs that require proficiency with languages you're familiar with or deal with technologies in domains you're interested/have experience in.

I think there is an incentive not to. If you buy Apple hardware, you are stuck with these stores. They know you will complain but ultimately comply and accept.
Airbnb markets it as you have access to the entire property as in an entire house. If you’re traveling with a family this is ideal but really hard to filter out if they let all sorts of apartments show up as an entire house. I believe they have or had a filter for apartments but honestly their search is really hard to get exactly what you’re looking for. The other thing you see is “entire home” actually being a bungalow in someone’s backyard.
