Interesting, but way harder than it sounds. Very often log systems live as a service for multiple microservices that do real world work. Propagating sentinel data through each of those systems is a nightmare because:

- those systems often have real-world secondary effects

- they sometimes have a tendency to validate away sentinel data prior to logging because the data is no good (e.g. a credit card number that isn't real or a password for a user that doesn't exist), although that can depend on scale and cost

- cross-team coordination of how to handle the sentinel data introduces coupling across teams/services which is contrary to the goal of microservices.
Are there any good open source live sync tools? Even one way sync with rsync is slow and two way is as you say a kludge. Seems like there is not much open source stuff out there for this and certainly nothing that can sync like these cloud drive apps.

Seems an expensive proposition. Experience is great, but what you can learn on a job tends to be very narrowly focused. You will learn a lot more broadly useful stuff from high school & future employers will take you more seriously, especially if you add a CS degree (or higher).

High school just gives you more opportunities down the road, which is the most important thing at your age.
Finally what happens if you lose the job? Then you would be left high & dry.

PS - At your age I spent most of my spare time programming on my own which gave me a lot of freedom to explore different things, not something you get in a job.

(1) When we investigated this last year the ammonia synthesis capex looked untenable and we didn't see a path to lower that capex. Re:injection wells... they are super common in Texas/Louisiana region as well, which happens to be where most of the US refining capacity and ammonia production is located, so we're very near customers there.

(2) 6000 dry lbs/acre/year = 3 dry tons/acre/year which is an extremely low yield. Even miscanthus and switchgrass get over 10 dry tons/acre/year, energy cane gets to 20 dry tons/acre/year and our grass gets to 25+ dry tons/acre/year. So that brings your $100/acre/year up to $800+/acre/year. Then for the chemistry it's important to note that much of the hydrogen gas produced is actually coming from H2O that reacts with carbon in the cellulose to produce 2 H2 + CO2. So, stoichiometrically you get significantly more than the elemental hydrogen content of the grass itself. That gets you another factor of 2 or so... and then we're at the $1750/acre/year mentioned in the parent comment.

(3) Agreed the transportation costs are better for ammonia, but we aren't actually transporting the hydrogen except over a feeder pipe into a refinery or ammonia plant. It's cheaper and simpler to transport the grass as opposed to the hydrogen, mostly because you get to avoid the pre-transport compression energy and losses. Again, as in (1) the issue with ammonia is the heavy capex based around Haber-Bosch pressure vessels and compressors... we didn't have any good ideas for reducing those costs, so there's no sense in competing there.

(4) We weren't at YC's demo day... not sure what you're referring to ¯\_(ツ)_/¯
Funny. I wrote a blog post sometime back claiming that an external real or perceived threat is a unifying factor for societies and nations.

So if we want to unite the earth, we need an extra terrestrial threat. It could be asteroid or alien invasion. Now these are less probable, hence we should set up Martian colonies and then just allow the earthlings to do their thing. They will eventually treat Mars humans as a threat. This is our only option to unify the earth.

Starting at 8:10 is the question and discussion about 'well why didn't the pilots just follow the runaway trim procedure?' And the short answer is MCAS upset is more insidious because it's inconsistent and includes a startle factor that pilots have not trained for compared to runaway trim.

~10:30 is an interesting discussion on the unique perspective of a jump pilot, who played a role in Lion Air 34's successful recovery from apparent MCAS upset. This is consistent with the findings in the AF 447 accident, when the off duty captain returned to the cockpit.

Addition:
At ~20:50, the assertion is that MCAS also has throttle authority. This is the first I've heard of this. It makes complete sense it would do this if it thinks there's a stall. But it just compounds the problem, by increasing airspeed the stabilizer trim has even more authority over the elevator. But to not tell pilots about what amounts to autothrottle? Incredible if this is born out. (There is a lot of conflict on what all MCAS does or can do.)

Why exactly did the US go so crazy against drugs? Seems like after WWII this war on drugs mentality took root and probably peaked in the 1980s or so with the peak of the WWII generation's power.
I used to be this way. I found that working in an editor using asciidoc/markdown is way easier for me. Copy/paste is faster than pen/paper. Also, I can write down notes and snippets of code to make life easier when I am trying to show someone what is going on in the source. Another advantage is I edit things to reflect the current state of the source and not get messed up by older notes/writings.

Not too long ago I heard a quip by Joe Rogan that you might find interesting.

DMT is a Schedule I controlled substance in the USA, meaning it's illegal to be in possession of it in any amount. Yet it's a chemical that we all produce naturally in our own bodies (endogenous) in small amounts. So in a strict sense we're all guilty of a felony for being "holders" of this illegal substance.
> Edit: as per the other comment, if the original exists only on video and not film, perhaps this is the best we're going to get.

I don't think that's quite right, at least it doesn't jibe with what the DS9Doc people have been doing (which consists partly of remastering pieces of DS9 scenes):

https://www.indiegogo.com/projects/what-we-left-behind-star-...

I think the footage really was on film, but the issue was that it was composited with low-quality CGI effects, or something like that. So you can rescan the film, but you have to redo all the compositing (and probably with your own models because I'm guessing the original CGI didn't look that good). That's why a DS9 remaster is so expensive.

The economics you're looking at for biogas and electrolysis look roughly right to me. But our models suggest that thermal gasification of biomass can get down to $1/kg. So then you're looking at $4.50+/kg for electrolysis or $1/kg for gasification... and you can see how all that math changes.

Electrolysis also typically costs more than you'd expect as soon as you add the requirement of renewable energy supply. Usually the renewable energy supply is solar, which has a ~30% duty cycle. So 70% of the time your electrolyzer is sitting idle. This crushes your economics and makes solar-powered electrolysis untenable in all of the analyses I've seen. We didn't have any clever ideas for how to change that situation, so after looking at it ~1.5 years ago we decided to look elsewhere.

Stuff like this makes it feel like the USA is falling apart from being a 1st world nation, crumbling in bits and pieces into a 3rd world one.

That's exactly the wrong take-away!

Amtrak is totally irrelevant for trans-continental travel. There is a "daily" departure from Seattle to Chicago. I.e. one train per day. Probably a few hundred passengers on a good day.

I just did a quick check and there are 7 non-stop flights tomorrow from Seattle to Chicago. Average air travel time is about 4 hours. Cheapest fare for tomorrow is $262.

So this train exists for a few tourists and for a few people who can't or don't want to fly. Everyone else takes a non-stop plane and gets there in hours not in days.

It's an indication of the USA's wealth and bounty that we are willing to waste billions of dollars a year on useless vanity projects like this. Long distance Amtrak runs at a loss, the US congress provides $1.3 billion a year to make up the difference. In addition there is a $650 million subsidy for passenger trains between Washington DC and Boston. That's arguably something useful, since the route is heavily traveled. https://www.usatoday.com/story/news/2018/03/21/amtrak-gets-n...

The idea with periodically detonating thermonuclear weapons on US soil, to remind people how bad things can get, is incredible (from 25:00 onwards).

I recently showed my Russian friend an article in The Economist about the arrest of Michael Calvey [1], which concluded in a pessimistic tone that just about anyone can be arrested and go to jail there. To my surprise he said "well, yes, it's true". I couldn't comprehend why would anyone like to live in such conditions.

But then I realized that an arrest and an unfair sentence in Russia is nothing. Neither is a 10*C global warming, economic meltdown 30x stronger than 2008, neither is twenty 9/11s in a week, when compared to a nuclear wasteland. We're all in more dire circumstances than Mr Calvey is in.

Living in Korea, it's just baffling to see these ridiculous, archaic attitudes toward marijuana in Korea and Japan.

It's like stepping into a time machine. The internet and its resources are available, yet no amount of reasoning or information gets through to a lot of people. Marijuana is just "evil" or only "people who commit/will commit crimes" use it.

I don't necessarily think the attitude here should be just like in the US, but at least let people use it medically, and get rid of the disproportionate stigma.

As @laureig mentioned, one can’t even admit trying marijuana in polite/semi-polite company (of other Koreans). With foreigners it’s a little different. Generally it only gets discussed if you’re closer with them.

At the same time, alcohol [and alcoholism] is not only totally fine, it's encouraged! Sometimes it's even mandatory to go drinking with your coworkers after work, due to social pressure from peers and bosses. I have spoken with a few people like this.

But going to clubs in 홍대 Hongdae/강남 Gangnam and drinking until 9am or drinking at a dozen bars in Golden Gai until 6am is totally fine. Drinking until you puke on the street is totally fine. (Admittedly I did do this once in 세종시 Sejong-City, Korea)

This test has some interesting edge cases though:

For example, I can own 200lbs of crystal meth, and when the police come to arrest me for it, they will have no problem claiming I own it. But according to this rule, I don't actually own the drugs because those same cops will prevent me from selling it.
What's more baffling is that it's totally acceptable to be an alcoholic and in a lot of workplaces it can be seen as negative to not participate in heavy drinking events.

It's hard to believe that one single ideologue had so much influence, and directly caused so much suffering to so many people.

> Marihuana is a short cut to the insane asylum. Smoke marihuana cigarettes for a month and what was once your brain will be nothing but a storehouse of horrid specters.

> Anslinger collected dubious anecdotes of marijuana causing crime and violence, and ignored contrary evidence such as doctor Walter Bromberg, who pointed out that substance abuse and crime are heavily confounded and that none of a group of 2,216 criminal convictions he examined were clearly done under marijuana's influence,[9] or a discussion forwarded to him by the American Medical Association in which 29 of 30 pharmacists and drug industry representatives objected to his proposals to ban marijuana. One such statement claimed that the proposal was "Absolute rot. It is not necessary. I have never known of its misuse.", although only the single dissenter (who noted he had once encountered a doctor who had been addicted to marijuana) was preserved in Bureau files.

Not that this is a recommended solution, but VPNs work from inside of China.

I lived with some Chinese students while I was exchanging and basically they said most people that want out of the Fire wall can just VPN out with no repercussions expected. Not that it’s ideal, but some commenters seem to believe that people in China have no access to the outside world which just isn’t true.

Before the internet the USSR could censor effectively, but now it’s pretty hard with encryption being as good as it is.

Of course there are people in China that don’t know that VPNs exist, but I think it’s an important nuance to mention that many people are able to have an open online experience.
Unless you consider reference counting to be a form of GC¹, Swift is not a GC'ed language.

Well, I like "unison" -- it is a well designed, two way sync app.

I personally run it in "-auto" mode -- every time I run the program, it shows me all actions it wants to do, any conflicts it detected, and asks me if I want to proceed.

If you want to run live mode, you can just run:

unison -ui text -repeat 5 . ssh://remote-host/dir

it will check for changes every 5 seconds, sync over any changes, and skip all the conflicts. You'll have to re-run it without -repeat option to resolve the conflicts.

We've been eye-ing it for a while at remind.com. Our hangup has been that we're heavily aws focused, but https://github.com/amzn/smoke-aws is looking promising.

We're interested because it's one of a handful of statically typed functional programming languages. Haskell/Ocaml are great as ML type languages, but it's a big paradigm shift for a team to jump into. Rust still has a pretty decent learning curve. Swift seems to have landed nicely in the "anyone can pick it up" territory. Kotlin is also in that territory, but the JVM is a beast.

For now, we're heavily focused on Typescript as the statically typed functional language, and we leverage types pretty aggressively (conditional types, discriminant unions, etc). Our iOS devs bring a lot of the Swift style over to our backend Typescript systems and from what I've experienced I think Swift absolutely will have a place in backend development.

It's possible, I actually don't know much about those weapons. Perhaps a better idea is to do it at the sea, with front row seats in Los Angeles, IDK. But that's kind of the point - we should have more collective wisdom about devices that can reign global destruction in a matter of hours, or less.

As I understand it, it’s largely a focusing issue. Close to the visible range, a distant point source gets focused to a point on the retina. At 1550nm, the energy is deposited uniformly on the cornea unless the laser is focused to a tiny spot on the cornea.
