Anecdotal - a friend of mine still farms full time. He row crops in the midwest US. One of his fields butts up against the local small town. Last year, on the north side of the field, the rows are arrow straight. The south side were squirrely and curved all over compared to them.

When I asked what the hell happened, he said the auto-steer went out, and by the time he figured out how to even run the planter while it was planting, he was done.

He laughed and said that the biggest problem wasn't the loss in yield, it was that he dropped his psp and broke it.
Think about landing at an airport in the before times and getting an Uber. You don't just put a marker on a map view, you have to be directed to where the airport set up ride share pickups. The drivers who want to wait in a queue to pickup airport riders need to be told where they're allowed to wait. There are millions of little edge cases like this, all with different, non-standard laws in every city they operate in. It's not just running a big server that keeps a table of pickup coordinates.

There’s a lot of hope from school systems that they will just be back next year, but hopefully there’s at least some behind the scenes work on making remote learning work. I have a lot of admiration for teachers & students working on switching over right now, in the event of further disruptions next year, they’re going to be so much better prepared.
Well I don't set my metronome to 120 and jam to it tho.. but kidding aside, that's exactly why I made the comment.

Peugeot, the car company, invented the pepper grinder and still makes them.

They started making pepper grinders before they made cars though, so perhaps you could argue they're a kitchen tools company that also makes cars.

Hmm, This reminds me a lot like Zenos paradox.

Also, I’d like to understand how if we can say 99.999... is = 100, wouldn’t we also be able to say 99.9999888999... = 99.9999..., and therefore also just 100? And so on?
I've done a few projects interfacing embedded devices, and the "I must guess at the device's state because the manufacturer didn't think communicating that was important" scenario fills me with sadness and rage. I'd love to slap around every developer who thought that making such a device was a good idea.
In math, when assuming the existence of something proved a contradiction, we conclude that the thing does not exist. The description may exist "integer between 3 and 4", but there is not described object. A description names a set or a class, and that class can have 0,1, or more numbers.
I think you mean quadratically.
Why the hostility?

Sure we have the benefit of hindsight to solutions that fit within the product demand fitness landscape. But by identifying areas we could have attacked, we shape our intuition and gain the confidence to exploit other areas of opportunity. That's valuable.

I think this warrants a reframing - instead of focusing on missed opportunities, look ahead for new ones. There will be gradients for the foreseeable future. Learn to spot them, learn the skills you need, and then position yourself to solve the problems.

With the knowledge I have now, I could have built Facebook, Twitter, Uber. But I didn't know to do it then. I'm trying to put myself in the right place to solve problems that matter to me that I also think could move the needle.
A layoff is certainly a sign that they hired too much, I agree.

I was going off what I figured the poster was getting at: they don't understand how Uber has even 80% of their employees.
But it's not about employees. It's about capabilities, and working backwards.

eg look at datastores. If you can fit your data in postgres on a single (potentially really expensive!) computer, you probably need two or three of those computers for a primary plus a couple replicas and a DBA.

Once you outgrow that, going distributed costs a team. There is a big elbow in the cost and headcount curve.

Once you want a different specific capability beyond the standard distributed datastores, that costs multiple teams. Yet another big elbow in the cost and headcount curve.

This happens on data stores, applications, translations, currency, etc etc etc. Imagine a Greek person with a Greek bank account driving Uber in France being paid with an American amex card.
> Unless I'm reading it wrong, this does not mean that Taiwan had any additional knowledge other than what they had read from publicly available information.

You are reading it wrong. Taiwan also relayed that PRC doctors were talking to ROC doctors, letting them know that the staff at hospitals were being infected with a new respiratory illness, which would indicate human-to-human spread. They told the WHO about this in December, the WHO continued to contend that there was "no evidence" to suggest human to human spread.

While yes, better launch capability == cheaper to put telescopes in orbit == good for astronomy, its not that simple.

Interferometry is HARD. The Keck telescopes which sit 100m apart on the surface of the earth were designed to be used as an interferometer and never lived up to the expectations. The interferometry abilities were shut down about a decade ago. Here's an article which includes a quote from one of the people who designed it who talks about spending 100s of nights trying to get this to work [1]. This only works because these telescopes are physically connected (see the discussion of the VLT in [2]). You are cavalierly talking about getting this working with 1000s of telescopes in space. If you are wondering how we got the event horizon interferometer if it is as hard as I am claiming, things become much easier at long wavelengths [2]. That's why we have lots of radio (ALMA, SKA) interferometers and almost no optical.

> At ~1.2Eur for the ELT, that would imply $45m per "hubble".

One of these is on a mountain, the other is in space. One you can plug into the mains, the other you need batteries and solar panels etc. One you know how it is oriented (its on the earth) the other you need gyroscopes and control systems and etc. One you can plug an ethernet cable into to get the data, the other you need some sort of transmitting receiving system. One I can go fix with a spanner if something goes wrong, the other costs another X if it does.

> Seems doable

If you ignore all the complexity of being in space, all the complexity of working with an array of telescopes, the fact that interferometry is way harder in optical, yeah it sounds great!

>people are less likely to hold corporate debt and instead hold cash. People are less likely to hold corporate debt because the corporation has less revenue to service its debt.

This omits part of the investing dynamic and is too simplistic of a conclusion for what's going on right now. There has been sky high investment grade issuance over the past two months and there doesn't seem to be a lack of demand for it. What changes is the price the market demands to hold any asset. There is always a price and that's why companies (cruise and airlines) that are in way worse shape than Uber have been able to raise money both in the debt and equity markets.

>if Uber were to try to sell bonds, the spread over, say, treasuries, would probably be above 8-10%.

> In other words, corporate debt isn't priced according to lowered rates.

These two statements are contradictory. Nothing exists in a vacuum but all else equal, if rates are lower, issuers are usually able to issue for lower all-in yields. Additionally, high yield is a much more idiosyncratic market with way less interest rate sensitivity and new issuance is almost always priced on yield; not spread.

> The only way the Fed would help would be if the Fed bought Uber's bonds, but that would require Uber to be investment grade, which would be laughable, or a "fallen angel", a company which was investment grade before the crisis but has since been downgraded.

The Fed has already helped Uber as well as other high yield companies through the various facilities it has announced. They are not directly affected by any of them but as with all central bank policies, it creates a reach for yield that flows all the way down.
> So no way children seven to fifteen years old can do it.

You shouldn't generalize from your own experience like that.
Don't forget schools are also designed to keep kids off the labor market until they're ~18.

Imagine what giving all those 13 year olds $2/hour jobs would do to the labor market.
It's lunacy. I have no idea about the man or who he is but 30-odd year old incidents should never ruin a person's career. This reeks of moral panic.

Recon the Hydra Cave: a development note of Rust on GCC (part 1)
Teachers and school district are not prepared to provide a curriculum for distance learning. It's takes months and years to develop a curriculum and no one had time to do that. Teachers may be doing their best but there's nothing wrong with stepping back and choosing to provide a different experience for your kid. Preparation for adulthood happens in different ways and parents should recognize that.

Also, parenting is hard and involves trade-offs every day. There are always going to be things you give up on to win the battles you can win.

well, from my point of view i write 40% the amount of code with react hooks than i did with react classes, i probably reused about 40% more code, and can write components 50% faster than before. i also refer to React documentation about half as much as before.

If, as I strongly suspect, full self-driving requires artificial general intelligence, Waymo's algorithms will not get there no matter how long they run simulations or even how many real road tests they do.
And I take exception to your extremely ignorant comment.

>The issue is a matter of culture, not of access to teachers or the Internet. I home school my children and they have NO access to the Internet

Leaving aside the part of "absolutely NO access to the Internet", which already puts a cult-like vibe on your whole comment, how can you say that? How can you say "access to teachers and resources doesn't matter"?? Your kids definitely have incredible access to resources (if not teachers, in the traditional sense), so I struggle to think how you can produce such an egregious affirmation!

Some of these children from low income areas are subject to deprivations that you wouldn't even believe. Some of them have no mother or father, or no home, let alone a "positive family culture". They study in underfunded schools in a neglected and neglectful system. If you had even the slightest idea of what it was to be in their shoes... To go hungry to school. To hear your parents fighting as you try to concentrate for an important test. To be shivering with cold at night. To live surrounded with pervasive violence. To have your shit stolen all the time, having to be on your guard. To be bullied. To be engulfed in an inescapable, all-encompassing feeling of pure hopelessness. Maybe you do and you don't care? I'm not sure.

I am pretty sure modern agriculture does a lot of this based on keeping track of everything (what's planted, how much fertilizer, weather, soil conditions, etc).

Nix uses `cargo vendor` to literally vendor the source of all dependencies as a separate derivation. Maybe cargo keeps a global cache of the source as well when doing `cargo vendor`, I don't know, but Nix does construct a derivation that contains just the vendored dependency sources and then provides that as input when building the full crate.
To give you some perspective when I left the fertilizer business here in Central Michigan in 1999 the only monitor in most tractor cabs was the seed monitor. In combines maybe 2-3% of farmers had a yield monitor, probably 2-3X that in places like Illinois or Iowa.

I love it how people say farmers don't use technology!

A fake watch (Armstrong IIRC. Wasn't waterproof as it should have been, and - too late - realized the word "water resistant" was misspelled.)

A fake wire sodder, which was pretty expensive and cost me in damage to the item I wanted to build. I turned to the manufacturer and complained, and they asked me to send images... it was a fake.

We got Desitin with a very weird consistency and smell. I am convinced it is not real, and have been afraid to use it.

An external disk drive, wich wasn't fake, but was also clearly not the brand it said on the box. I complained about that, and am still waiting for a resolution.

I absolutely don't want to criticize, so I hope this doesn't come off that way. I'm wondering if this situation is making you (and people in your situation) re-think some of your life choices.

Venezuela - and, frankly, the rest of the world - is reliant on monetary policy set by outside parties, who can also impose explicit (import/export) and de facto (loan terms) sanctions should their political positioning be undesirable.

How much does the US government subsidize the average US citizen in services, tax rebates, etc.? Is it more or less than what Venezuela offered its citizens in cash payments? I honestly don't know, but I've become more convinced lately that Venezuela's issues have less to do with the efficacy of their policies than they do objections to the nature of their intended distribution of wealth.

I've been running multics on simh for a while - it's amazing and a revelation to experience some of the ways that it surpasses UNIX (memory safe implementation in PL/I -> no stack and buffer overflows, unified storage model, nested ring security and system call architecture, long command forms, etc.) while also trying out ancient forms of email, emacs, lisp, BASIC, C and Fortran as well as weird and obsolete, but historically interesting, languages like BCPL (predecessor of C) and PL/I (predecessor of... nothing, probably, except maybe Ada in some sense.)

If modern UNIX/Linux distros were to adopt three features from Multics, I'd love to see memory safe compilation, long-form commands (e.g. in multics, "ls" is a shortcut for "list-segments"), and ring security (which is basically flexible nested paravirtualization, enabling many of the things we currently do with VMs, containers, and user mode drivers.)

It's also not surprising that the most racist people are also the loudest.
