That's not the issue. Most jobs at companies that matter do.
China's traffic feels more dangerous because it is: they have 50% more auto accident related deaths than the USA does (see https://en.wikipedia.org/wiki/List_of_countries_by_traffic-r...). My Hunanese wife's dad was killed by one of those loosely regulated and very dangerous blue trucks (if you live in China, you know what I mean). I've seen someone die in a traffic accident before in Beijing (this person was biking across the street (dongzhimen wai) against a red light, and got hit by a taxi cab trying to beat the light before it turned red the other way). You can never really get that image/sound out of your head (and things slow down when you see it, to be fair, the cyclist was clearly at fault, but the taxi driver was also speeding).
Synthesizers provide a wide array of different types of instrument in one housing (brass, strings, pads) in addition to effects and sequencers. This means a synthesizer can supplant what would have classically been one or many different people in a band. The same goes for drum machines.

DAWs provide most of the benefits of synthesizers and drum machines with the additional benefit of being a production studio.

You rightly point out the barrier to cost is being reduced but, in my opinion, this goes hand in hand with complexity. After all, I "could have just hired a band" to experiment, play around and bring my vision of music to life. Is putting a band in a computer for less than $300 "just a matter of reducing cost"? Encapsulating complexity is often synonymous with reducing cost.

Any tool, even ones that are cheap and/or encapsulate complexity, require training to use well. The question is whether they can be used "professionally" with a modicum of training or whether they need a lifetime. A good artist can probably be proficient enough with a synthesizer, drum machine and/or DAW in a year or two before starting to create quality work. It takes a lifetime to become a professional at the piano or violin, often requiring exponential more work for increasingly marginal gains.
I thought that this summer. This I found out hotels are charging double normal if they even have rooms open.

Probably another local specific thing though.
I agree with points 2 and 3, but I think it's easy for people to be attentive and take notes during the meeting, especially if they are part of the discussion. My handwriting is too illegible for me to consider this option. I only resort to handwritten notes on my ipad if there isn't enough space for me to pull out my laptop.

In Vancouver we have a local service (evo) that was competing with car2go, but since car2go pulled out they seem to be doing quite well. I suspect the reason car2go "failed" was that it was more about pushing the smartcar into the north american market that was fairly reluctant to buy smaller cars, than it was about actually providing that service. When smartcars showed they weren't going to take off here, they had no reason to keep it going.
Inter-process communication is much, much slower than a native function-call. (Native function calls are almost free, especially on modern CPUs which are very good at dealing with them.) Spinning up a whole new process is vastly slower still, taking (iirc) hundreds of thousands of instructions.

I don't see how it would help things to wrap it up with concurrency abstractions. That won't make the cost go away.

I think part of it is because the language that those ideas are built on is intentionally very slippery. If you aren't extremely careful with how you word things, you wind up sounding like you're denying factual historical events.

John McWhorter is the only voice I've heard so far who can reveal the swiss-cheese nature of the set of beliefs contained by the term 'CRT', and do so in the very language of the educated class that espouses CRT.
> In response, Netflix released a statement which read, “Netflix has only the utmost respect for Ms. Gaprindashvili and her illustrious career, but we believe this claim has no merit and will vigorously defend the case.”

Netflix could have done better with this one. Instead of “vigorously defend the case” they should have settled and publicly apologized to Ms. Gaprindashvili for this insult.
Journalists reporting things that others would like to remain secret is kind of a huge part of the job description of journalists, especially investigative ones, considering moral and newsworthy aspects of course. A free press is a very integral part of a free society.

If she wrote about what things Cook does in the privacy of his bedroom, then you'd have a point (unless he is doing something illegal and it becomes newsworthy again), as it's none of our business at all, immoral to report and just not newsworthy.

But she is reporting on what the Apple leadership says about the company to thousands of employees, that may affect millions of lives one way or another. It's not private information by any means, it's not even trade secrets. It's company-internal information at best, maybe some things that Apple might not like to get out, but they didn't exactly like it either when journalists were running stories about the work conditions at Apple partners/suppliers/vendors like Foxconn either.
I have been in the same boat. It wasn't 100 years old, and it wasn't a furniture company, but it ended exactly the way yardie described it :-) No one wants you there because they see you as a waste of money and a threat. A lesson to be learnt I guess.

> Our recommendation system is built on the simple principle of helping people find the videos they want to watch and that will give them value

Well it doesn't live up to the principle, not even close.

> It’s constantly evolving, learning every day from over 80 billion pieces of information we call signals.

This is probably why. It's a positive feedback loop mechanism for noise.

Another reason why is probably that it's metric for "give them value" is engagement. Its a dishonest metric, because "gives them value" is less important than "give us value", so even if you found that it doesnt give them value, you've got a perverse incentive to continue doing it and pretending it is in their best interest.
How come you had Ginkgo stocks?
no, they're bad ideas that are generally acceptable in certain parts of the mainstream, at least where i sit in the world, which isn't a liberal place at all. those are quite typical opinions for a conservative.

i'm skeptical that you would lose your job for expressing these out loud, but perhaps you're right that you would. i don't know because i don't know where you work. pretty sure that firing somebody over an opinion is illegal but i'm no lawyer? seems the line would be crossed if it interfered with work or harmed somebody, not by simply expressing them online. but i don't want to get into an argument with you about this, because i can already tell you're gonna try and pick it apart with exceptions...maybe even share a news article where this happened.

if anything, to me, these opinions indicate that you're probably toxic, not a contrarian. generally toxic people think they're contrarian and pride themselves over that.
I generally agree with this, and I also think it implicitly serves a few other purposes in addition to being daycare. High school gets people used to the idea that they will spend their lives following a schedule and producing things. It also promotes the idea that we live in a community and teaches us about interacting with one another; (probably not in the most effective way). There’s also an element of teaching us about or maybe indoctrinating us into a particular system of work/reward which our society is supposed to operate under.

You have misunderstood something. Yes, that car was worth the price. It is the benchmark against which I am measuring newer cars. "Cars today", which is what we are talking about, give an experience that is unlike that one. (Including the Chevy Bolt @ $14k that you mention in your other comment, which is more like a Walmart car than a Costco car, and nowhere close to the price point I mentioned or the cost/value ratio of the reference car.) That that car lasted 200k, and would have been on its way to last another 100k at least, underscores my point, not undermines it.

For the reason above, the question is not "What kind of car did you expect?" It's "What kind of car do you expect to get?" And the answer is, "Considering the opportunity we have had to make technological progress, I would expect that I should be able to find a car today that is at least as good as that one. I should definitely not expect to be disappointed to find that as a general rule what's available is so much worse."

Their recommendation system is broken. Sometimes recommendations are completely unrelated, sometimes the same videos get recommended in every page for several days. Videos are usually tagged (there are browser extensions to view tags on videos), so recommendation can't even match the tags to view stuff in a similar ballpark. They demonetize and downplay recommendations for decent channels because they are deemed to geeky or are not posting videos frequently enough, I'm not at all pleased how Youtube gets more and more rotten.
But this only makes sense. If you're the first employee, then there's zero "social proof" that the startup is going anywhere. If you're the nth employee, the greater n is, the more social proof there is that the company is going places. Hence, the less equity you're going to get.

If one wants founder equity, found a company!

> Afghanistan became unwinnable the minute we lost sight of our goals.

No, I think it's worse than that. We straight up didn't even have a goal.

The most cynical and self-interested goal might have been, "set up a sustainable Afghan government that is no worse than the Taliban in terms of human rights, but not necessarily any better, as long as they don't harbor terrorists who attack America and our allies". The problem is that, as a goal, that's far too brutal and realistic for a Western country to explicitly get on board with in the 21st century. So we had to lie about maybe setting up a liberal democracy in Afghanistan even though everyone knew that was a stupid goal that would never actually work. In fact, it was such a stupid and unrealistic goal that we didn't even really fully commit to that goal out loud either.
I don't really agree. Refugees won't go into the countryside. A few years ago in France we had a influx of refugees, and the vast majority were around Paris or big cities in general. In the countryside no one saw anyone. Even in Lyon we didn't see many people.
I guess that means you've learned to care a lot about YouTube's recommendations? Another approach is to ignore them.
We bought so many doses that we are literally throwing them away! Meanwhile poor people on other continents go without. The admin wants people to have boosters. Are they, the current admin, wrong to push for boosters? The FDA members that have resigned might say so, but what about the old and infirm, and health care workers, who have rapidly waning protection?
> A decent e-bike costs that much

This is not a decent car. You are comparing an e-bike that is likely going to be bought by someone rich with a car that is likely going to be bought by someone poor. Also, China has plenty of e-bikes that are really cheap (and finding a decent one for $4k is really hard, it will probably cost $8k over there).
I'm pretty far from this stuff, so I am sure the people studying it know far more than I do.

However when I read about dark matter/energy, and quantum physics, it sometimes reminds me of stories of the geocentric model, where the scientists of the day derived this incredibly complex clockwork geometry of the solar system, to account for the strange curves the other planets seemed to take to cross the night's sky.

I wonder if we're similarly missing a key insight which will make these "strange results" fall into place.

On the other hand, it's entirely possible that we've just reached the limits of what can be found intuitive to our primitive ape brains.
Be careful with YouTube. For years people have talked about social media's effect on mental health, but personally, I've found the biggest hit to be YouTube.

Their recommendation system is really the heart of the beast. It's essentially a dopamine reward system, not too dissimilar from a slot machine at a casino. Pull the lever (refresh the page) and get random results! It sucks you in to a cycle of refreshing, finding videos you're interested in, clicking, rinse, repeat.

Personally I found myself losing hours per day to this behavior and gaining very little from it.

Far more productive, is going to YouTube for something SPECIFIC. Use the search function to find what you're looking for, and watch those videos, but never use the homepage or sidebar recommendations.

There are actually google chrome plugins which will totally remove the recommended section:

Wow - YC has been around for 15 years and only 7 IPOs. That is an interesting track record.
Anecdotal, but I've used Car2Go extensively and HATED the smart cars. Always felt like they would fall apart the next time I accelerated.

Car2Go (Mercedes) merged with DriveNow (BMW) and are now called ShareNow. VW also runs a service called WeShare. Its somewhat successfull in Germany. I regularly use them in Berlin.

ShareNow also only uses VWs electric cara. Mostly last gen VW Golf-e but recently also some ID.3 cars.
The SI units are not arbitrary quantities -- they are all physically derived quantities from water. For example, 1L of water weighs 1kg and and takes up 1000cc. Its density is 1000 kg/m^3. Simple.

235mL is just as easy to measure as 1 cup or 0.000992063492063492 Hogshead, you use your measuring cup.

They are absolutely inherently better! They are an advantage in daily life.

This is a very retrograde move. Imperial units are absurd and make calculations more difficult / less accurate.

Edit: The Kg is arbitrary (you need a single arbitrary base), but everything else is derived from physical phenomena, including seconds:
"The second is defined by taking the fixed numerical value of the cesium frequency ∆Cs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9,192,631,770 when expressed in the unit Hz, which is equal to s^–1."
It’s changed, I’m in the same boat. The only new channels I’ve found that I love are after seeing them promoted outside of YouTube. They clearly intersect with other channels I’ve subscribed to and watch regularly but were never recommended. I also notice that the recommendation queue for videos on these channels tries to steer you away to larger more mainstream channels that are only tenuously related.
"I'm grateful for the silent block in this case."

That's not the issue - the issue is not alerting the sender that the message has failed.

It's not a big deal if the receiver never receives the message - we can find a different way of reaching out or fix the content problem or whatever. But we never find out. As far as the sender is concerned, the message succeeded.

This is a problem and the very bad spam heuristics employed by even the most competent actors (gmail, for instance) mean that anyone can be impacted by this.

Uncontrollable vomiting due to marijuana use on rise, study finds
Also worth noting that meat processing plants in the US were temporarily shutting [1] down as well due to Covid, which was causing famers to start euthanizing live stock [2]. The Trump administration took action [3] to compel those plants to open under the Defense Production Act, although it's unclear if the executive order would have withstood a legal challenge [4], it did have the desired effect and farming and food processing resumed. Had the government not interfered in the operation of meat processing we might have much higher meat prices as well not to mention we would have likely had the same issues with food supply chains for raising live stock.

There is almost no point in working a job that pays under 20 dollars an hour in Florida. Rent here is skyrocketing and there is practically no public transport. Most restaurants here pay between 10 and 15 dollars an hour which just isn’t even worth it anymore.
The issues described (or rather, the lack of knowledge that is at the bottom of these issues) are not new, they are true for many, many forms of medicine we use today. ffs we don't even know how exactly virtually all medicine used in treatment of mental illnesses such as schizophrenia and depression work - most medical treatments consist of trying all available candidates and varying the dosage until you find a somewhat effective one - and yet we accept this lack of knowledge.

As for what this means for vaccines: It is by now widely accepted that a vaccination drastically reduces the effects of a COVID19 infection and all but eliminates the risk of fatal outcomes and that in billions of people vaccinated by billions of doses of various vaccines the side effects were negligibly small, and it is widely accepted that even in young healthy people, COVID19 can cause severe, even long-term cases. Therefore, the potential risks of vaccination are nowhere near as risky as risking the infection with the actual pathogen.
