I don't think there is anyone developing packages on pluto/jupyter, so I wouldn't worry about that. The most common method for that should be using an editor like VSCode (which will have some linting capabilities) with an open REPL and Revise [1]. What it does is every time you save any of your files (with some known restrictions), it will automatically and incrementally update the state of your application in the REPL, allowing you to probe your code whenever you want (with tons of introspection methods, up to interactively inspecting the native code being generated), and since you never leave the session you don't face the compiling latency more than once. I end up preferring this workflow for experimenting and data science stuff since it retains the structure and tooling of an editor with the ability to interact with my application (and really miss it when I'm writing Python applications), but of course each one has a preferred workflow and it'd be nice if Julia supported more of them as well.

Overselling + altering reports after the fact to fit a prosecution's preferred theory of the events.
It helps to fully understand the drawbacks of what you're advocating in order to have a coherent argument.

That's why people have issue with your statement on "easily" swapping hydrogen tanks, as it's anything but "easy".

>The device was never intended to be used this way in the first place.

The manufacturer has no say on the usage, simple as that. That there are better ways to tinker is irrelevant. It doesn't preclude the right of people to tinker with anything they own at their own convenience, including an iPhone if that's what they got.
Interesting, it seems there’s a youtube-dl fork with Sponsorblock integration: https://github.com/yt-dlp/yt-dlp#sponskrub-sponsorblock-opti...

Unfortunately, there doesn’t seem to be a build for the Raspberry Pi by the way…
This may be an overly naive take on my behalf, but if it was 25% on a Model 3 specifically that means each one costs them $30K~ to build at a $40K price (and frankly 25% is likely too optimistic for their lowest margin vehicle).

That makes me think we're many, many years away from seeing $25K~ EVs. You can cut some things off of the Model 3, but battery reduction in particular is a headache since you risk damaging your reputation/EV's reputations if you make it too weak (particularly with normal degradation).

I know this is proprietary/secret, but I'd love to see a pie chart of where each dollar on a Model 3 goes. In particular how much is pure battery/drive system, and basically the whole rest of the car.
Some light game theory to add to this discussion....

> A lot of people were hired on the condition of going into the office and I find it all the backlash from employees after being asked to go back into the office a bit absurd.

For all of the negative stuff coming from people who do not want to return to an office I find one thing in common: they all usually really like their company and job.

While "If you don't like it, leave" is the reality of the situation it doesn't change that this is somewhat irrational behavior. It is the {CEO, Boss, Manager}'s decision as to who gets to work remote obviously. That's the power dynamic at hand. However, if you think of this in any other situation you can see that there's something about remote work that makes some managers loose their cool. Imagine employees saying this:

1. I have back pain and if I had an (ergonomic chair|standing desk) I'd be able to work for longer without getting up and walking around. This would make me more productive.

2. The coffee machine makes bad coffee and everyone walks to the coffee shop across the street 3 times a day. If we just got good grinds and a machine in the office we'd all save money and we'd save ~1hr/day/engineer on context switching for coffee.

A {CEO, Boss, Manager) has every right to say: "If you don't like your (coffee|desk|chair) then you can leave" but they are obviously acting pretty childish here. If you look at all of these situations logically you're looking for a small input effort for a large continuous return on investment.

If you add into the fact that myself, and many others, think working from home makes us MUCH more productive you can arrive at the following conclusions:

1. We are not more productive, we just think we are.
2. We are more productive, and we commute less (save money + sanity).

If we think out this decision matrix:

- Employee + !Productive, Boss + WFH: the employee is no more productive - maybe even slightly less productive - and this comes up in their performance reviews and they're asked to come back to the office. The employee will probably see that WFH does not work for them if this performance review is fair (ex not "You called into the meeting but since you didn't come in person you were obviously not listening as well").

- Employee + Productive, Boss + !WFH: The employee can quit and find a WFH company. The employee may be willing to accept *less* money and will produce *more* value for the new employer. This new employer now has a major leg up (in most industries) over the old employer.

- Employee + !Productive, Boss + !WFH: The employee could still jump to another company for less wages at a lower output if WFH means a lot to them.

- Employee + Productive, Boss + WFH: Company gains efficiency for no extra money. Employee is happier.

In this chart we see in every situation except one the employee wins out over the company. In the situations in which the employer allows the employee to try WFH the employer wins out massively: their employee is either happy that they were given a chance or the company has found a way to make someone much more productive.
My general feel is that this is a pretty nonsense move.

Not sure if London is or is near where whatever this virtual summit is being "hosted", but I would point out: a couple dozen less ms latency can radically improve your ability to participate in a virtual chat.
People talk about battery fires in cars, but boy, are the willies I get from the thought of driving around with a pressurized hydrogen tank about a thousand times worse than whatever small chance of having a battery ignite.
the weird cadre of nuclear boosters

Inappropriate. If we are free to insult people we disagree with on here now, than I might as well say "the weird cadre of nuclear detractors".
Side note: This Verge piece looks like a rewrite/gloss of recent New York Times reporting: https://www.nytimes.com/2021/07/25/climate/toyota-electric-h...
Hydrogen for vehicles is very nearly fully developed. Honda says their upcoming generation is no more expensive to manufacture than an ICE vehicle.

The problem isn't with hydrogen vehicles, it is with the production of hydrogen itself. Once (IF) humanity licks the generation of electricity problem, hydrogen vehicles will be the mode of transportation for nearly everyone.
I'm not saying the law should be ignored. I'm just not entirely sure why the law exists as it does, or think that it's ill written to account for certain situations. A large bathroom with twenty people (or more! bathrooms at large events or in large airports can be big) in it is not what I would consider private.

I think (but could be wrong) what most people actually care about is that their stall is private (or in the case of urinals, that someone isn't to the side recording what they consider a small private wall space area), but since that's hard to account for and some stalls/urinals already have poor privacy to the rest of the bathroom, we got what we have now.

Honestly, to me it seems like a lot of bother to hide bits of our body that we should all be a lot less concerned about shame about in the first place, but I'm not holding my breath on any change there in the U.S.

"Fire & Fury" sold 2.3 million copies. Did it play a role in Trump not being re-elected?

Strawmanning an argument is poor form.

Mein Kampf has existed and been available, and hasn't actually really caused any harm. That doesn't make it a better book but the hallmark of liberal society is that we can tolerate dissent while an authoritarian one can not.
Jailbreaking is a bug, not a feature. These people need to realize the abusive relationship they have with their phone company and need to decide which way to go forward. Apple never promised to support jailbroken phones, they heavily and openly police modifications from the get-go.
Is there a difference between traits and multiple abstract inheritance? Those seem equivalent to me.

Re duck typing: people usually respond to "what is the type of map?" with "it's duck typed". But we should be able to do better.
I'll take an optimistic outlook and say this only looks bleak to us now, but will be a net-postive for human society in the long run. I see it as less of an end-of-the-world event and more as a gradual age of reckoning on a planetary scale. You can deny climate change and social unrest all you want until these things boil over and force changes to occur.
> the solution to that must not be to treat the user like a child unable to make decisions for themself

There is a wide gap between being unable to decide for oneself in the general case, like a child, and being unable to decide for oneself due to lack of expert knowledge. Sometimes, less is more. Apple built its brand on this insight.
After reading https://www.factcheck.org/2021/07/scicheck-fauci-and-paul-ro... (happy for someone to provide a better source), I'm not sure I agree with the idea that Fauci is "full of shit" based off of this one exchange.

Propane is a vastly different substance with different properties. I'm not sure why you are so insistent that they should be similar.

Sure, EVs and hydrogen each have their pros and cons. But that is meaningless without numbers. So far, it seems like the numbers work out a lot better for EVs.

Maybe someone comes up with a great idea and hydrogen becomes the future of cars. But there is zero evidence of that today.
SIV is usually done with AES/GMAC constructions but you could do it with ChaChaPoly just fine.

The big downside is that it requires two passes on encrypt: one to create the MAC and derive the IV and another to encrypt. The overhead for this is small for message/packet based systems though since after pass one the data will be sitting hot in the processor's L0 cache. Decryption can be done in one pass.
That doesn't mean he sold his shares.
I do wonder if you'd see similar reactionary claims about Elixir being a general-purpose language if the community experienced constant shallow and misinformed claims to the contrary (which Julia has in abundance, for some reason). Imagine if every 10th post about Elixir on HN was "I will never use it because I work in embedded and it has zero support there" when Nerves is a google search away.

From another perspective, if we consider "general purpose" to mean "focuses on most of the things I care about", then you could argue (and I'd agree) that Elixir appears more general purpose for a larger number of people. Specifically, most devs work on networked services, and networked services are bread and butter for BEAM languages.

Lastly, there is also a strong tendency to dismiss anything with a whiff of academic attachment as unfit for "real" industry work. This effects not just Julia, but also Scala, OCaml, Haskell, TLA+, and more. Though I do empathize with the perspective, It is often taken to the point of caricature-you can show someone a dozen companies using some tech and it'll be as if you said nothing at all!
For that figure to be true you would have to ignore the requirement that you maintain awareness and control of the vehicle at all times. Autopilot !== FSD. Your car did not "drive itself," you were in control of the car 100% of the time — at least I hope so...
No, we were not "considered both monkeys". Monkeys and humans share an ancestor that was not a monkey or a human.

Could you expand on what you mean by:

> The divergence must've happened down the hill somewhere. So, in the eyes of those in the future, we may or may not remain human.

I really cannot make sense of this.
>The UK was just clever enough to hide the export ban in their contracts with AZ (unlike the US which did it more bluntly). The first xx million doses of vaccines manufactured in Oxford/Keele had to be supplied to the UK. Which is an export ban in all but name.

I don't disagree that to country B waiting on doses, the outcome is the same whether or not the cause is country A implementing an export ban or country A having bought up all the doses by having signed the contract first. But there is a difference.

(The US never had an export ban, either. The US did the same thing as the UK; insist that they (which the US signed ahead of everyone else) would be fulfilled in the order they were signed.)
This is such a bizarre comment and your thesis is nowhere near being “transparently obvious”. You’re trying to link the people whose lungs were harmed by vitamin E acetate in black market vaping cartridges to COVID?

Credible genetic analysis of the virus shows nearly incontrovertibly that it originated in Wuhan.
The US is actually a net exporter of oil (and oil products), gas, and coal. So if we eliminated current consumption and production in the US, it would actually increase prices slightly overseas.

But to really answer your question:

1) We invest in tech and scale up to make renewable energy cheaper than fossil fuel. Other countries will benefit from our scale and tech improvements, reducing the relative competitiveness of fossil fuels.

2) ban production and exports of fossil fuels. Instead, actually export clean energy in the form of ammonia/nitrate fertilizer (from green hydrogen), liquid hydrogen, perhaps synthesized LNG, synth fuels, clean electricity.

3) border adjustments and a CO2-based import tarrif.

4) cultural imperialism making clean energy good (fast electric cars are an excellent example) and fossil fuels unpalatable.

5) International agreements and treaties.

6) tied to that, maybe targeted aid contingent on climate action.
There is definitely a lack of trust going on in a lot of places. There is also the question of building relationships. Ask any sales person if he/she thinks warming up a relationship is easier face-to-face or from a distance.

Then there is the fact that not everyone is efficient with WFH.

Finally, if one manages to split his tasks in batches WFH/office hybrid could definitely become an option for many, e.g. work with team in office one week / work on long form client emails remotely. But that's a very big IF.
> By that logic, what are firefighters doing but censoring homes?

Not inherently, but a disparity in which fires get prevented and put out and with which priority might constitute censorship, just as a disparity in which types of programs are identified as malware might. Many historical examples for the former instantly come to mind, from one library in alexandria to a sexual research institute in nazi germany. Not to imply that this is comparable to those in magnitude of course.

(On second thought, that also applies to systems of explicit censorship, where all media has to be approved but media that exhalts the government line has a higher chance of being approved than media that does not comment. As well as our system of implicit censorship, where every film company has to make money, but a movie produced with approval and material support of the US military has a significantly higher chance of being financially viable.)
If the total cost of ownership is lower with an EV, you can drag the payments out longer with lower interest financing because the vehicle will last longer. The upfront cost is higher, but you hack around it with financial engineering. I don't mind an 84 month auto loan at <2% interest, as long as it's cheap to drive (EVs are half the cost per mile as combustion vehicles) and retains enough value to defend against negative equity as the loan balance and vehicle value decline roughly at the same rate.

You might not see $25K new EVs, but you'll see used versions around that price with 100k+ miles on them that still drive like they're new (there are Model S and X vehicles with hundreds of thousands of miles on their drivetrain still going strong).

TLDR We're financially engineering our way out of combustion based transportation.
Answer : neither. Montréal has a density of 11.7k people per square mile. The vast majority of Montréal is duplexes. It works. Duplexes have a high density.

Perhaps now that you know that duplexes are closer in density to Hong Kong than to SFH, you can understand how most people live 30 mins away by bike from downtown.

Not all jobs are or have to be downtown either, it's just that a lot are.
I'd say I'm a solid developer (at least that's what my employers have always said!), but I've always really bombed in-person/live interviews. I think it was probably a personality thing, as I'm pretty all-over-the-place when speaking in person. In text though, I can polish my thoughts before sending them!

Automattic had (and still has) an interview process that was fully text-based via a combination of Slack, p2, and GitHub, and it really worked well for me. I didn't even speak to a person (on video) until a couple weeks into starting the job!

A completely text-based interview process works great for a variety of people: neurodiverse, people with accents/ESL, fidgety people, etc. Especially for remote companies where everyone communicates using text 90%+ of the time! I'm glad it's catching on, and I hope to see it expanded to more companies.
This is interesting, I hadn't seen this paper before.

I've had a citric acid allergy (both natural and mold-produced) most of my adult life, but it really seemed to kick into high gear after I spent an extended period of time living somewhere with severe mold problems. Since some people in this thread seem to be unaware of the black mold/citric acid relationship entirely, I'll further clarify that aspergillus niger, the citric-acid-producing "black mold" on rotting fruit, is not the "black mold" associated with wet drywall. (The place I was staying had both...)

Since it's only a single anecdote, and I'm not an immunologist, I've had no way to reason about whether these could be connected. Good to see at least someone is studying it in some cursory way.
> I understand that around the 90s owning anything with an OS also implied the ability to mess with the box of bolts and circuits that run the OS but that’s no longer the case. At least not when it comes to phones.

Incorrect.
It is still the case with nearly all Android phones. You can install any OS version, gain full permissions, mess with kernels, modules, frameworks, recoveries, ...

Comparing revenue to a prior quarter when their factory was shutdown due to a pandemic is a little disingenuous. Look at “same store” sales (same market, like China or Europe) over time for the real growth story.
Yeah, no. That's not what generics mean. A map of any single type with any type for the key is different from a map using generic types.

For generics what you want is not interface{}, which says nothing, but a type T that has meaningful constraints.
Yea Rand doesn't know what he's talking about.
COVID makes it worse, but the erosion of participation in structured social groups (fraternal organizations, sports leagues, churches, etc.) has been on the decline for a long, long time. Less participation means less funding means less outreach means even less participation means less groups in total, means less participation, etc.; down and down it goes. Now even the paycheck-compelled participation in the office environment is eroding.

For many people, making new friends as an adult gets harder with age. Part of that is that we're not compelled to join things like we were as children. Part of it is that we have the cumulative time and means to create our own favored environments - my house has some kick-ass stuff in it and air conditioning, so why would I leave it? :D I kid, but kinda not.

As I've gotten older, I've made a point to get more involved in entirely voluntary organizations (collector's groups, church, etc) and it takes work. It's rewarding on the balance - good for my personal growth and good for the group assuming they would agree that I bring a modicum of value to the table - but it takes a dedication that doesn't come easy. Kind of like exercise, right?

An antipattern here is expecting to replicate your quality childhood friendships quickly. Friendships, particularly intimate friendships, take a long time and many shared experiences. 80% of the job is just showing up, so nothing kills budding friendship opportunities like flaking out one too many times. Show up!
Still doesn't stop the phenomena of everyone thinking "oh, someone else will call."

Clearly so many nightmarish things about this setup, but the one that makes my skin crawl is: my chair. Can you imagine having to sit in a different, random office chair every single day? It's like getting in your car every morning and someone has adjusted your seat and mirrors. I'd probably resort to hiding my favorite chair in a broom closet. Not to mention having to sit in the dried sweat and crumbs of who-knows-how-many other people all the time. shivers.
