All my subway experience is pre-COVID.

I dunno what the regs say, or what the MTA publicizes, but the reality is almost any station in Brooklyn, Queens, Harlem, etc. is going to be unsupervised in the late hours. Maybe there’s somebody lurking in an annex somewhere, but the ticket/info booth will be locked up and no MTA personnel, not even a janitor, will be visible. This was even the case for heavily trafficked stops like Bedford or Lorimer on the L.
> Commit when you have a coherent piece of work done.

No, that's the problem.

Commit when you are available to deal with the consequences of commit. Having a coherent piece of work reduces, but does not eliminate the chance for problems. If you leave before the code builds, you've created problems for someone else to fix. If you haven't budgeted time for the rollback to go wrong on the first try, you're creating problems for other people.

This is why reliability and responsiveness of CI/CD systems matter much more than most people allow. On a good project, pushing things after 4 is probably a bad idea. On less well run systems, anything after 3 might be risky. On a bad one, 2:30 might be pushing things. So depending on meetings and lunch time there may be very small intervals where you can push things, and when the clock is ticking we begin to rationalize, which just makes the likelihood of failure increase.

Simple incentives seem to explain that one without needing much of a conspiracy:

If you're buddy-buddy with the cops, they'll help promote you, talk to you about cool cases they worked, etc.. If you're instead critical of the cops, they're going to try and undermine you instead.

This means that doing a cop show that's anti-cop would be like doing a medical show without ever being able to consult a doctor. You can do it, but you're going to have to put a lot more work into research to get the same sense of verisimilitude.

There are other things to consider too:

- Tesla is achieving vertical integration to a degree no other mainstream auto OEM has achieved. The only other example of vertical integration to the extreme that I can think of is Koeneigsegg, and they are _very_ niche. This only helps Tesla make cheaper cars faster while collecting more margin per car.

- Tesla's FSD marketing is highly contentious, but they are the only auto manufacturer that is building (designing) their own SoCs explicitly for this. I wouldn't be surprised if they are outspending other auto OEMs on autonomous driving R&D by several degrees of magnitude.

- Tesla still has a major, major lead in EV battery tech which will only be cemented if they can get 4680 into revenue production. They also own the largest and (arguably) most reliable charging network in the world, which is growing at a faster rate than Electrify America, the second biggest competitor.

I think that Tesla is overpriced long term in a world where 91% of American cars are EVs and 48% of them are self-driving, but I think they are correctly priced for _right now_

There are still fewer than 10 billion people on the planet. I realize people can have multiple accounts, but realistically let's limit it to something like 1 billion actual users. Why does everybody need 100 recommendations a day?

It's a slight tangent, but it seems somewhat relevant - they're not only making so many recommendations, but the recommendations seem to be universally hated (judging by the comments here). It's like they're bragging about how epic their fuckup is.
All the standard comments about battery breakthrough articles apply. Who here is tracking which emerging battery technologies will hit scale manufacturing first and how much of a difference will they make for cars, stationary storage and personal electronics from a cost, weight and volume perspective?
Agreed, I view projects like this as important experiments and inspiration for the wider community. It's good to have people around that are willing to try out implementing lofty and idealogical ideas - even if it ultimately fails at it's intended goals directly, they occasionally spawn the most uniquely valuable unintentional gifts to civilisation.

Yeah, I mean it worked. Projects got delivered on time, I assume on budget, and functioning to spec. Lacks in some places were compensated with excesses in others. Some things were not pretty, but there's no denying the place ran like a well oiled machine. I learned a lot there.

At the time I thought the in-house knowledge and expertise these people would take with them when they moved elsewhere would be a big loss, but then the company was bought and dissolved into a larger parent, and that knowledge mattered exactly zero.

> these positions are "covered", meaning that someone can sell a put option while owning as many stocks as they sell in options

A covered call is where you sell options backed by long shares. A covered put is backed by short shares. A common way of selling puts without shorting the underlying stock is just having enough cash on hand to buy the underlying asset if the option is exercised.

And yeah, some small investors do claim to make decent income primarily writing options. The basic idea is that if you can eke out like 0.5% a week on average, you can get around 25% annual returns. I've been looking into trying to automate some basic strategies, but it's rather daunting just getting started in automated trading. Figuring out how to just get the data you need for implementing a strategy is a pretty big hurdle, for instance.
The Linux terminal is not a good environment for that.

The Windows terminal supports key-up events... as long as I can remember anyway. I think a number of Windows programmers who are looking at Linux's command-line API wonder why its so hard to get something that's common in Windows.
Mobile data is quite expensive in many parts of the world. Quality is just one factor.
If you need to cover your short and there are no shares being sold you effectively must keep offering higher and higher prices until someone will sell you a share as you are legally obligated to buy a share[1]. To end the unlimited downside (of raising the price you'll pay by more and more) you need to have enough sell orders on the books to cover your short or have raised the price enough for someone to sell. During the time you are trying to buy your loss is increasing (as you raise the price to get a seller) and is unbounded.

If you have a stock you have to sell and there are no offers to buy on the books you can't offer to sell then keep raising the price, instead you would need to keep lowering the price.
The price is either limited by what's on the books, or you need to wait an indeterminate amount of time for some one to buy at the price you are selling. During this time you are trying to sell your profit is decreasing (as you lower the price to get a buyer) and bounded by $0 (for a limited liability company).

So while it's true that if you hold a stock indefinitely the value you could get is unlimited with a short the value you could lose could be unlimited over a much shorter time frame.

[1] Whether you actually need to cover your shorts may be a matter of some debate if you look at the wild rumors around GME
> I don’t have much sympathy for people that commit actual crimes. There are too many innocent people being arrested to worry about the guilty ones.

What's an actual crime to you? I bet our definitions differ based on something not-so-quantifiable. A good DA can produce charges against someone to make it look like an actual crime was committed when it's really something petty or much less nefarious. We've seen countless examples of this.

Rather than describing my sympathies at some nebulous level, I'd rather say this: I have sympathy for those in the criminal justice system because I realize most people are capable of change and that is mostly ignored by the public and the criminal justice system together. Former criminals are almost never rehabbed, and worse we see many examples of folks who were never criminals being introduced to a system that by default does not care about them but carries maximal implications for their life.

Some interesting parallels with automotive industry here. Cisco saw huge valuation base on a perceived future. Nortel (who were more of an incumbent) also saw massive stock price increases at that time. Only one of these two companies survived. Cisco had the right tech but Nortel had fundamentally the wrong tech. I suspect we'll see something similar in the automotive industry.

Any actual scientist (and not an "expert") know how long these things take. It took from 2002 to 2020 (edit: or was it 2018? I can't remember) to find a closely related SARS host (as in "not a match but close enough to point to a likely cause"). I find it very telling that we get lots of articles stating lots of stuff but not really any real scientific research papers on the source. I'm also not seeing any of these scientists volunteer to live for years in remote locations taking anal swaps of animals to actually find the cause. I believe what we are seeing are the science equivalent to armchair generals.
Both those I linked seem to work fine, though the tapes I'm recovering from are mostly in good condition. The Python one is a bit more robust than the one included with ti99sim, but much much slower and picky about DC offset.

(Note that both of these also decode the TI's frame format; but it should be easy to pull out the core waveform decoder of either.)

iPhones are not a commodity product. At the moment Teslas are. How will Tesla convince consumers that their car, with a high profit margin, is worth it over a mature EV vehicle from Ford, BMW, etc.
I don't think a lot of people dismissed the "lab theory" per se. The people who were coopting the theory were also the folks who called in intentional/by design. We had evidence for neither and yet suddenly it had become an excuse to yell epithets at random people on the street.
It is certain that some series of events led to the pandemic.

There exists a class of people who, without necessarily being driven by other motivations, generally try to find out what is really going on. We call such people scientists.

No need to focus on motivation. Curiosity should be enough.
Similar here. I differentiate by how little I care about revealing my actual identity and location. Like for hobbies and stuff I really don’t care if people know my approximate location. But for some stuff… dudes are crazy. Would rather not get doxxed.
> Out of the box, VIM has no easy way to colorize tabs.

This is slightly simplified from my .vimrc:

It will highlight any tab in dark red.

(My actual .vimrc uses /\t\| \+$/ to also highlight extra spaces at the ends of lines.)

I hate (and am confused by) pretty much everything about vimscript, but this particular snippet is actually surprisingly clear.
In regards to your first point, I am saying that Wayland does not do what it sets out to do and the proper way of doing it is a much larger problem than what Wayland can address. It is possibly better to avoid breaking everyone's stuff if you're just going to need to shortly do it again to fix the things Wayland does not and can not fix.

For your latter point, Wayland is much different. In Windows there are ways to inject behavior into other programs or the UI elements. This exists so you can change the UI. Wayland's idea of security is very much against that, at least in the way it can be done on Windows/X11.

I like it, but I'm also afraid of it.

Lithium metal reacts explosively to water, and it's impossible to avoid a vehicle battery cracking open in a bad enough accident. Physics is a stern task master.

Existing lithium ion batteries are pretty dangerous, as we've seen from accidents involving Teslas and the like: but so are gasoline autos.

It would be hard to persuade me that these batteries aren't substantially more dangerous still.

That all said, rapid recharging could be a useful feature for stationary storage batteries, and the higher energy density is a nice bonus, although space isn't really the limiting factor for storing renewable energy. There's a place for this technology, somewhere.

I'm always happy to read about new battery chemistry, but always come back to the slogan: Goodenough's batteries are good enough.

Generally speaking, the smaller the subreddit the better the community. I really like the subreddit dedicated to my favorite baseball team. I like the /r/MLB subreddit too, but less so. The noise noise from everyone posting and trying to make the frontpage leads to an inevitable degradation in quality.

I remember a while back when /r/cfb was invited to join the front page and there was considerable pushback from members who were afraid the reddit-wide readership would ruin the quality of posts. Kind of an eternal september thing...
> Tesla is achieving vertical integration to a degree no other mainstream auto OEM has achieved

This is crucial. It’s also why Tesla vs automakers reminds me of Apple iPhone vs existing cell phones. Sure making an electric car is “not that hard,” but because the carmakers didn’t take Tesla seriously for 10+ years, they now have a lot of catching up to do.
We can get computers to make things up, sure. But usually when they "zoom and enhance" on TV it's because they want to see what's really there.
Look here. The pin is at the western side of the base.

It's IDF headquarters, used to be bigger (from an old British camp, back when Tel Aviv hadn't grown to swallow it up), but the army has been steadily selling off the valuable urban land and relocating functions to less central locations.

Then you have other academics in the comments saying nothing is certain yet, and other prominents labs like Gupta Labs at Cambridge and Bloom Lab from Seattle saying there could be multiple explanations.

I know the issue is politicised and that's wrong as Ecohealth alliance from the US sponsored this research so there is no "single country at fault" - no need to avoid topics.

It's not "chinas fault" it's more like, what on earth was the US based Ecohealth alliance doing with this research, why so many previous lab leaks with little attention, what is the history if the Wuhan lab, whats the actual facts about Gain of Function research etc. All topics that the press is not looking into for some reason.

On Ecohealth alliance:

“ It later turned out that the Lancet letter had been organized and drafted by Peter Daszak, president of the EcoHealth Alliance of New York. Daszak’s organization funded coronavirus research at the Wuhan Institute of Virology. If the SARS2 virus had indeed escaped from research he funded, Daszak would be potentially culpable. This acute conflict of interest was not declared to the Lancet’s readers. To the contrary, the letter concluded, “We declare no competing interests.””

Was your relative a multiple-time offender? If so, maybe stronger punishment earlier would have put him on the right path sooner.

Look, some people will always be fuck ups. That’s the sad reality of the life. Some people, no matter how their are guided, will always eventually fuck up and ruin all the hard work people put into them. They are wired to always make poor decisions no matter what. My best friend is like this. After 40 years of trying to help him, I accept him as he is now with no expectations he will ever get better despite decades of trying to help him. I have a close relative like that too. If they are protected from
consequences too early in life, they tend to make larger, irrevocable mistakes later in life and then they are fucked for a long time.

In SF crime is running rampant now because of a DA that refuses to prosecute smaller crimes. It has emboldened criminals. Prop 47 has made it so that gangs of thugs enter a store, fill their bags with merchandise and run out with no repercussions. I witnessed this with my own eyes and the manager said they don’t even call the cops anymore because they won’t come. Instead, 15 Walgreens have closed their stores in SF in the last few years because of it. Criminals are arrested 20+ times in the span of a year and they keep getting let go and they are free to continue committing crimes and it’s getting worse and worse.

So punishing criminals matter. Putting them on the right path matters but it can’t be consequence-free.
