First time you use it, sure you'll get a different one. Only lasts two years instead of a lifetime ... people just think "oh things break" and buy whatever the supermarket has.

Actually a spatula is one of my growing list of "there's no way that wasn't designed to break". Wooden-handled spatula with silicon head, the spatula handle looked like it went in to the silicon and provided a strong head. But instead the silicon was designed to look as if the wood continued in to it, but instead there was a very narrow wooden extension a couple of millimetres thick. This was an expensive branded spatula from a specialist store.

The spatula snapped at the interface of the head and handle; you could make it much stronger _and_ use less material.

It wasn't this one, https://cdn.cutleryandmore.com/products/large/35515.jpg, but same exterior appearance where the handle appears to extend in to the silicone.
It's there in Canada too, malls in some location are withering but as you note others are booming.

Just to add to the comments above you, all of the Alamo Drafthouses I've been to have been the best screen and audio I've been to. I've frequented chains and independent theaters. But I should point out that I don't live in a city as big as SF, so it's just one man's opinion. Your AMC and Cinemark might just be better.

This isn't a quirk of JS at all. It's somebody purposefully calling `parseInt` incorrectly.
> I absolutely disagree that we didn’t experience life-changing performance improvements.

Of course I don't disagree with this either. But this (as well as trying to run modern internet websites on older hardware) doesn't mean much- it's a fact that software always fills up all the capacity allowed by hardware, sometimes with features, but more often with frills and more layers of indirection. What I disagree with is that javascript (and browsers) were too slow to make interactive web applications: in fact they were possible, and the ones we still use were born around 2005: gmail (probably faster then than now), google spreadsheets, maps (I made a complex dashboard in 2005 incorporating microsoft maps, that became bing) etc.

Programming was much more "close to the metal"- as much as this means anything in a web browser- but the results were usable- not as graphically fancy or feature rich as today's, but ok for many use cases.

Bundle sizes also have exploded as a result of the complexity of the frameworks. But that doesn't mean the applications are more interactive or have more features, they're just fancier and, from the point of view of developers, more maintainable.
I've never had an offer where they refused to tell me the pool or percentage. This would be a hard pass. You cannot properly evaluate the offer without this information.

The information about the state of hedge funds takes time to travel, anyone that has been in the quant field knows about these practices. Now that data science and machine learning are becoming more accessible to the public, I'm not surprised that articles are being made on it. There is value in this data now that we have better data processing abilities. There was less technical value in the past and now there is less competitive value in the present.
The cynic in me thinks Elon would first buy up all the property around the impact zone for pennies through a bunch of shell companies, then send up a BFR or FH with a W84 warhead (designed for a cruise missile so it would be extremely light relative to the lift capacity), rig it with an impact detonator that could be activated post liftoff, and then drive it into the asteroid.

Save the day, collect the gratitude of a grateful nation, and then sell off all the property at an obscene profit to make back all the costs.
I was comparing their #1 Cold Spring Harbor Lab to HHMI Janelia Research Campus, which doesn't even seem to be ranked in the top 100. Yet when I look at the research output, it seems pretty similar with the nod to Janelia in terms of FC, top article Altmetric score and article count.

https://go.nature.com/2x8zE68 (Janelia Nature Index FC = 36.41)

vs

https://go.nature.com/2RsQl5n (CSHL Nature Index FC = 31.24)

So the denominator for the # of articles per Dimensions must be much higher or N/A and disqualifies some institutions? Unfortunately the Dimensions article count isn't viewable for any institution not making the top 100 list.

I wouldn't call those sub-languages, I think they're rightly different languages (of eerie similarity) born from specific pedagogical or academic vision. So the upkeep in dealing with the mismatch between proper Racket and these student languages wasn't something I was interested in. Students should be able to consult general Racket resources.
I, for one, don't care about my phone. I routinely forget where I put it. I use it a total of ~15 minutes a day.

My desktop computer, on the other hand, I check hacker news every 5 minutes. Even if I know there's nothing of interest or I've already read all the comments about things I care about, I check just in case.
The racket docs having such great cross-referencing with hyperlinks is probably a decent part of why it's been relatively so popular. Cross-referenced documentation invites deeper investigation and learning.

> This is in an environment with constitutionally guaranteed fundamental rights to privacy (that cannot be reversed by the govt)

There is no data privacy law in India as yet. The one drafted last year has many issues. Saying that the government cannot reverse it is naive. The government can make laws that side with corporates and itself, without providing adequate protections for citizens.

The Aadhaar linkage and re-enablement for use by private companies in contravention to the Supreme Court verdict is another sign that the government can, and will, do what it wants. The Supreme Court is unfortunately not proactive in issues that have the potential to affect all the people in the country.
This was apparently a plot point in Billions.

There's market opportunity here. Off the top of my head:

1) Drone photos instead of satellite photos to get at the data cheaper

2) ML counting of cars

3) Some way to legally sense the number of cellphones within a given radius (can possibly be combined with a drone)

4) Simply aiming a network cam at the entrance/exit from across the street and counting the number of people that enter and exit via ML

All of these could get you at public data that highly correlates with retail sales
Fox News is the status quo.

Generally you should prefer few large propellers over many small ones due to aerodynamic efficiency. Stacking up motors axially sounds like a very good idea though.

Data provides advantage, but it's also a liability. If you collect the data and store it, then it can leak out (perfect anonymization is a pipe dream). Or you can get hacked.

More generally, using collected data means you are making decisions based on something that some of your users don't want you to have. That may be fine if you're careful with the data and you provide something of value in return, but the minute you do something that your users don't like, then they can reasonably blame you for acting against their best interests.

If you carry around a can of spray paint, don't be surprised if you get blamed for graffiti.

The Recent Upsurge of R&D Productivity in Pharmaceuticals
There are a lot of things that electric planes will not be able to do unless there are drastic changes in battery technology. They can still fill a niche for short flights with very little cargo/person capacity.
So all of that already exists and is already widely used. I'm a bit confused as to why this is news considering that this has been going on for quite some time.
Unfortunately the battery weight is also currently prohibitive for small companies such as Harbour Air and Mokulele.

Several weeks before the Harbour Air / MagniX announcement I ran through an exercise to determine the range/payload of an electric Cessna 208 (Caravan) for a typical flight profile here in the bay area: the daily FedEx flight from Oakland International to some nearby city, such as Petaluma. This involves a 5min climb from take-off to 2000ft, some period of cruise flight (ultimately determined by range), and a 7min decent to land.

This calculation assumes that the C208 swaps the swaps its turbine (PT6A-114A) for the Magni500, saving 85lbs. It also accounts for the substantial increase in conversion efficiency between the MagniX and PT6 (roughly 0.94 from 0.32). Not accounted for are any differences in aircraft systems (de-ice, prop pitch, electric instruments, plumbing, etc).

The results are not surprising given what others have noted about the enormous difference between the specific energy densities of Jet A and LIB. At the specific energy density of today's production batteries, 250 w-hr/kg, the electric C208 could carry one 175lb pilot approximately 100mi in 39min. Due to FAA VFR regulations, this would in reality limit the flight to 9min (FAA requires daytime reserve of 30min), with the subsequent loss in range.

Let's consider the putative solid state battery at 500 w-hr/kg. Now a 60min flight time (really 30min plus 30min reserve) will allow 1080lb payload. Fantastic! That's a pilot plus 4-5 passengers. The catch, of course, is that the timeline for road worthy SS batteries is 5-10 years. How long for before an air worthy battery is available?

With this information parsing the press statements is a little easier. Will the Harbour Air / MagniX Beaver carry 6 passengers over a 30min flight? No. It may demonstrate electric flight of a utility category air frame with the pilot as the "soul" payload. After that both companies will likely be in the same position as the rest of us -- waiting on better battery technology.
For anyone else alarmed at "wait so this isn't a complete fiction?", it's a 'tabletop simulation' -- a thought experiment but written down, to try and track down who would (should) be doing which tasks and how it might play out.
In Billions, Bobby shrugs off saying - everyone does that, tell me something new. So I thought this is already pretty popular.

Yes, and it would be great if Firefox blocked those messages altogether. Persuading a user to disable safety features is not ok.

I don't really understand the title. Before I call clickbait, how did this destroy the world? Sure, house prices will fall in the predicted impact zone, people will panic and create shortages of essentials in a much wider region, and the worldwide economy is set back by a decade or two. But destroying the world before impact? What?
The word "Common" is a reference to the language Common Lisp: https://en.wikipedia.org/wiki/Common_Lisp.

No explicit link with the tragedy of the commons was implied. Implicitly, of course, it applies - there are many participants, each of which is aware of their own gain and unaware of how their actions cost everyone else. The result is that when they all get their changes in, the result is terrible for everyone.

For another example, C++ is a terrible language, but it contains many good ones.
I've started, to the greatest extent possible and practical, eliminating single-use plastics from my life.

If something comes in either a metal can and and a plastic pouch, even if it is more expensive I'll buy the metal can version.

A glass jar can be recycled or will break down into sand, a metal can can be recycled or turn into rust, a paper or cardboard container may be recyclable and will break down into mush.

A plastic bag or jar is unlikely to be recycled and the polymer chains that it is made up of will remain on earth for a human-scale definition of "forever" slowly breaking down into microscopic pieces that get into the water and are carried by slight breezes.

Hopefully, one day, soon, single-use plastics will be seen as a colossal mistake on par with lead in gasoline, radium clocks, asbestos tiles, and dumping industrial waste into waterways.

Small changes add up. I have a container of yogurt nearly every day. That's ~350 plastic cups into the fake "recycling" stream every year. Last year I started weaning myself off plastics and now make my own yogurt in an Instant Pot. It takes minutes of effort spread over 9 hours. The milk I get comes in a glass jar from a local CSA that reuses the jars when I return them for more milk and then I put the yogurt in mason jars.

20 years from now those mason jars will still be usable and 7,000 plastic cups will have not been consumed, "recycled", shipped to Asia, and burned in open pits.

Please just spend a couple of minutes and think of how you can lower your plastic use.
A bytecode is easier to keep stable than an AST is; an AST changes as the language changes, but that doesn't mean you have to change the bytecode, only change the transformation from the AST to the bytecode.

I have no idea if this is the reason, but it's a possible one.

This is constantly repeated, but it's not true. I work in the field of electric motors for electric aircraft, and the amount of nonsense constantly repeated on the Internet about how electric flight cannot be done without a breakthrough is breathtaking.

Electric motors can achieve FAR greater than 1kW/kg. Here's one used sometimes on electric aircraft capable of 10kW/kg, same as a jet engine: https://emrax.com/products/emrax-268/

The specific energy of lithium-ion is poor, but jet fuel's USEFUL specific energy is more like 10-15MJ/kg due to needing to be burned. There's also some efficiency improvement possible, i.e. from airliner lift-to-drag of 16-20 (and like 8-10 for a Cessna) to a more glider-like L/D of 25-35 (the best gliders can do 70). Additionally, improved modern materials means you can just have most of your take-off mass be battery, compensating for the poorer specific energy (general aviation craft are only like 10-15% fuel, but 777s can be almost 50% fuel, and electric aircraft could be 60% battery).

So if you combine efficiency improvements and high battery mass, sure, electric planes still may have a tenth the range of jet liners. But jets like the 777 have a range of 10,000 to 15,000km. A tenth of that is still over 1000km! Quite doable for a very large portion of domestic flights. Since domestic flights often involve multiple hops anyway (due to hub and spoke model), you could fly basically anywhere up and down the eastern seaboard in just the typical two hops. And faster than high speed rail.

But of course, there are already better lithium batteries that are available in small quantities, like lithium-sulfur, metal electrode lithium batteries, solid-state batteries, or batteries that combine those various features. ~1.5MJ/kg cells are already demonstrated and you can buy them on an evaluation basis. ~2MJ/kg is feasible as well, enabling single-hop flights all over the eastern seaboard and enabling multi-hop transatlantic flights (as low as 1200km is the minimum range needed for transatlantic flights if you really wanted to do it).

I spent the first decade or so of my career not taking any notes at all. Constantly, I was forgetting little things after meetings, spacing out on information after a week or a month or whatever. Now I keep a notebook on my desk at all times and I write with a pen. I constantly write down what I am doing, what I am working on, what I am thinking, the gist of conversations that I have throughout the day, and more. More information is always better. I find that writing in pen is better than pencil because I am not tempted to try to fix when I spell a word wrong or make some other kind of error, and I find that physically writing things out with a writing utensil is much easier for me to maintain verbal conversations vs typing the notes out with a keyboard.

It seems to me that the notebooks create their own value, and you have to start somewhere to begin seeing the value. Then you will find that value and you will accelerate your usage of note taking.

Notebooks can be a really incredible tool - if someone asks me what happened on the first Tuesday in May, I can flip through my notebooks and figure it out. If I wonder what the heck I was thinking as I was writing a PR, I can check the date of the PR and find my notes. I've never once regretted taking a notes and now I will likely never stop.
Go does this really, really well. I'm not a huge fan of Go-the-language (largely because I enjoy having a little more abstractive power), but I have to admit that one of its huge strengths is that it's a language designed to take the focus off the language and onto the program you're writing. It avoided several of the pitfalls of more "advanced" languages (eg. Common Lisp, Haskell, even Rust and Python 3.5+) in the process, which is perhaps why it's seen more mainstream adoption.

Kotlin's another language that looked at say Scala (which is an immensely powerful language, but easily lets you get lost in abstractions), decided "We don't need that feature unless it actively helps remove friction when writing programs", and ended up with a lot more real-world programs written in it.
Thanks! I guess that answers my question. So the timing of both sources should match each other.
That looks awesome. Our local equivalent-ish, Cinetopia, recently closed and I'd love for someone else to step in and provide an even better experience. One reason I don't typically go to the theater is because I hate everything but the movie itself. I'm willing to pay for a premium experience.
I wouldn't take Armageddon as an instruction guide of how to safely get rid of asteroids. In fact, detonating it would likely lead to a shotgun effect. Lots of smaller pieces. Sure, these wouldn't do as much damage to a single city but they could damage many cities and many objects in orbit. Beyond that you now have to contend with the political ramifications of causing the destruction of someone else's property.

Tldr: asteroid defense is quite hard. Currently we are not adequately equipped to do so it safely.
