Believe me, I've been in the other side.

Initially I set all kinds of amazing OKRs for the tech team: decrease MTTF , MTTR; increase system performance, decrease bug reports, and a lot of other things that on an engineering paper would be great.

But then reality hits: next product feature has to be released NOW. Customer X is complaining because sales promised feature Y but we dont have it, Z provider decided to change from REST to SOAP and the reality is that your MVP code has rest tightly coupled. Oh and the engineers that knew about that code left when google/Facebook offered them 10x payment and free margaritas.
> also lets people conspire in secret to overthrow governments

The USA was founded on this principle, and the framers felt it important enough to enshrine in the 1st and 4th amendment. Some could argue the possibility of citizen overthrow helped keep corruption in check for the first 200 years (but probably no longer).

I don't think this property is an absolute (in all cases) bad property.

I stand corrected! I thought I remembered this from reading the Swift docs day one. So much for my long term memory.
You only have to understand how to move your character using WASD, the concept of Inventory and pointing at different places on the ground with a cursor. Failing to understand this simple set of rules would disqualify a person from most jobs ever invented.
I'm sorry that I have nothing more to say than that this is incredible! And I love the minimal white aesthetics! So slick! It's not The Mother of All Demos but it's up there.
isn't the best technical interview inherently just doing the job itself? find some aspects of the job that's representative of it and have the candidate do it - if they can, then you're hired.

the issue is with technical jobs it's difficult to surmise what exactly is "representative" to begin with. I imagine the only reason candidates aren't just asked to work in the actual job for say, 8 hours instead of doing say, 7 irrelevant 45min interviews is because of intellectual property.

I wonder if Google or another large company has ever tried to re-interview all employees with more than say, 4 years of experience and correlated their interview performance with past job performance.
I certainly feel this way. There are too many MBA-types who aren't really competent at the low-level technical work they manage and don't really even have an understanding of it. It's hard for me not to be resentful about it. I know that's my own ego talking but it's the truth. I changed my career trajectory to avoid folks like that
It's okay to use a non-standard abbreviation if you spell it out the first time it's used followed by the abbreviation in parentheses, like "individual contributor (IC)", and then use the abbreviation in the rest of the text.
It is interesting to see new perspectives though, I am glad HN allows this after some time. Time changes everything.
The only really critically necessary government intervention is making sure the grid can handle this.

It would probably help if they mandated smart electric storage heaters on new builds but beyond that I'm not sure you need to do much more.

You can rely on people's self interest to buy a new washing machine that saves them money, for instance.

I would encourage you to find a different philosphy for life. My undertandings are built upon my religous beliefs. I won't share my religous views as I am not trying to convert you :-) What I will say is that my view of wealth is well thought through and based on ancient teachings which have stood the test of time. I found myself very conflicted about wealth and success when I relied on my own thoughts and the internet. Maybe do some reading on finding happines and less on other people's success stories. These people are often 1 in a million. Can I finish by encouraging you that you are obviously someone who has the drive to better themself.
Easy to cherry pick WW2, which is pretty different from CIA secret ops overthrowing democracies and installing fascist dictators.
> The single benefit of Uber having a global presence likely already outweighs the value of these local coops.

That and a willingness to subsidize rides to the tune of billions of dollars per year. A coop is going to struggle to provide rides at a "competitive" rate when the competition is paying people to use their services.

"For all of 2020, Uber's net losses amounted to $6.77 billion..." Ref: https://www.cnbc.com/2021/02/10/uber-earnings-q4-2020-.html
Part of the design of Coops is that they are the local interest. It’s much less likely that they will encounter local resistance than a VC-backed Silicon Valley overlord.
There are many challenges. For example, the ocean is a harsh environment. Also, testing at scale is tough because of the environmental permits needed to test in the ocean. But more importantly, how many people will be okay with wave machine offshore where people from shore can see them? People of nearly all political persuasions don't like manmade objects in the oceans. I don't know how a wave energy industry overcomes this.

Isn't a factory a large distributed system? What's the difference between this and a visual programming language like LabVIEW?
Defining string as a sequence of unicode codepoints is the mistake.

Nobody ever cares about unicode codepoints. You either want the number of bytes or the width of the string on screen.

UTF-32 codepoints waste space and give you neither.
I took a use of force course from the criminal justice department in college. What they said is that originally (maybe until sometime in the 40s?) it was legal for police to shoot a fleeing suspect if the crime was a felony.

That has since changed and it is now only legal to shoot a fleeing suspect if they pose an immediate safety threat. For example, if the suspect was armed and fleeing into a populated area.
The vast majority of people travelling for work aren’t doing so by plane. From the perspective of overland transport, people going to/from airports are the 1%. The 99% are all the people who's jobs don't involve them flying anywhere.

I also apologize for my overly confrontational approach. I mistook you as one of the wumaodang (fifty-cent party) who keeps denying and apologizing CCP behavior. (There is one such user with exactly this user name in some of the comments in this post.)

I just searched for 小熊维尼 and 小熊维 on bilibili, and got the same findings as this thread: https://old.reddit.com/r/China_irl/comments/m9vziq/%E5%AD%98...

Winnie-the-Pooh videos are clearly censored when you searched for 小熊维尼 (you only get generic Disney videos), but you can bypass the filter and find a few genuine Winnie-the-Pooh videos if you only search for 小熊维. The censorship is ongoing, even though not universal.
No, the notation says that cats are to marsupials as covid is to humans. I think they're saying that cats are a plague on marsupials.
> But the costs over time are negligible [...]

In heavy industry, they're very much not. Large machines often cost large amounts of money. You don't want large machines sitting around doing nothing when they could do useful work and earn money instead – so that you can, for example, pay off the loans you took out for them, or pay the operational staff that pulls the levers and turns the switches.
All right, that's fair - I think that approach leads to something like like, country A should not do morally-questionable action M, nor should country B, and if country A chooses to do it anyway, this shouldn't justify country B saying "Well why can't we" - country B should stick to its position and criticize country A. I'd agree with that.

(I originally read your comment as saying that it is unfair for country B to be enjoined from action M if country A is engaging in it, and I think other commenters did too. I do absolutely agree with the goal of collectively constructing a better good in a fair and equal way, holding everyone to that standard, and expecting that people will fail but it's worth trying to meet that standard nonetheless.)

I like how Go handles this case by providing the utf8.DecodeRune/utf8.DecodeRuneInString functions which return each individual "rune" as well as the size in code points.

Coming from python2, for me it was the first time I saw a language handle unicode so gracefully.
> How one treats intelligence activity or law enforcement activity driven under democratic oversight within a lawfully elected representative government is very different from that of an authoritarian regime.

That's the kind of self-delusion you only get from a power-hungry government official.
I might argue then that your company does a bad job at hiring :) Also, do you also ask yourself: what is my manager doing? I do and in good, healthy companies I can see that.
Only that I didn’t know about it! I’ve only admired Haskell from afar.
When you're talking about lowest demand are you talking about for the whole grid? A city block? A building? A condo?

And I agree. I worked in solar and storage for a while. It's not a replacement, it's just an extension.

It works out ok for a battery system for a building but anything larger they just don't last long enough

Ask HN: Which types of tech companies are getting acquired?
The short answer is we don’t know yet. Our most pressing goal is getting solutions to customer problems in their hands as fast as possible (and learning from how they use it), and sometime the pricing lags this goal.

This was built by a team (Bots) that my team works closely with to bring to market, e.g., bot scores can be used in Firewall Rules and combined with other capabilities.

We’ll be working soon to determine pricing and exactly how this will be exposed in the product.

If you’re in interested in beta testing this, drop me an email and I’ll connect you with the right PM: pat at cloudflare.
I agree with the sentiment, but the ability to study (read guides) and demonstrate understanding/retention of the material by actually doing something (playing Factorio) is a good signal.
The Crisis of Venture Capital: America’s Broken Startup System
When I was responsible for recruiting interns, I always wanted to use TIS-100 as an interview tool, or more likely a modified version of TIS-100 with different instructions/architecture to not give an advantage to people that have "played" it before.

It would test their ability to read documentation and apply what they've read to problem. It also doesn't rely on them memorizing frameworks/API's etc. And it even in the early "levels" you can ask them to optimize for program size or cycle-count. Unfortunately no one would let me do it.
My boss can code better than I do, but he doesn't have the time, he's got CTO stuff to do instead. So I code and he CTOs, and everything tuns out well.

Ouch! Try answering that in some Java Spring or C# MVC code. Then try to answer it in some not class-based Django or Rails code.

It gets worse. From the article: "Total acquisition costs now exceed $428 billion, nearly double the initial estimate of $233 billion, with projected lifetime operations and maintenance costs of $1.727 trillion."

Much like the SLS, it seems that it is more a jobs program to dump money into select congressional districts than a project actually focused on deliverables.

Neat, but we need thousands of Hoover dam's, including the lake at the top and bottom, to store enough energy just for the US. Or to put it a different way, imagine completely draining lake Superior in just two weeks, and then over the next two weeks completely refilling it.

I'm not saying it isn't neat, but it doesn't scale to as much storage as we need.
Overall, they seem to be a better "bundle" than the IPO of capital and going public. You know exact dilution and capital raised, lower regulatory burden, but are expensive for companies.

Direct listings are more price optimal.

It's traditional IPOs that don't make much sense to me anymore. More burden & more uncertainty than SPACs + higher cost than direct listings.
Basically the Coefficient of performance (COP or SCOP for seasonal version) just keeps going down with the temperature (under 1 means resistance heating is better)

Models made for cold climate work to around -30c. Wikipedia has okish writeup about their functionality in cold climates

https://en.wikipedia.org/wiki/Air_source_heat_pump#In_cold_c...

Don't really have any good sources in English for this (most reading I have done on this is in Finnish)

For example here are some excerpts from a report done by VTT (the Finnish governments research center)

https://www.scanoffice.fi/vttn-testiraportit-ilmalampopumppu...

If you scroll down you can find some pics "lämpökerroin" is COP and "ulkoilman lämpötila" is outside temperature.

From that you can see that the combo of Mitsubishi Electric MSZ-LN25VGW + MUZ-LN25VGHZ still holds a COP of 2 at -30c. On the models not made for such climate/cheap ones you can see it drop to 1 (or below)
I'm critiquing the premise of the article. That there is a simplicity to this problem that is overwhelming and refreshing, so much so that there's no divisive or insane discourse possible around it. In fact there is a lot of it, and boy is it stupid!

>The simplicity of the stuck big boat doesn't matter to some people. The schizos have already done their research and figured out that it's Hillary Clinton's boat, and that it was EMP'd in a show of force to metaphorically represent her imprisonment. And the fact that they don't just take a few tugs and pull it out is because they are doing it on purpose to disrupt world trade enough to justify the "great reset." Not only that but it's become a nexus for all kinds of bigotry. Basic misapprehensions likes "oh wow, those idiots only sent one excavator!" become pyres for racial hatred (i.e. of course they can't figure it out, they're middle eastern).

>There's your look into the insanoverse that some of our compatriots live in.

Don't stick your head in the sand. The problems that affect all of the rest of our worlds understanding of events are also at play here.
It’s unclear if this article is satire or not. Given that you will be spending 20 hours of at least two people’s time (one candidate, at least one employee), the space of alternative interviews is quite large. You could, for example, spend 20 hours observing them perform an actual software task. This piece doesn’t consider alternatives at all, merely asserting that this particular 20 hour game is the best that can be done. I see no reason to believe that comparing the play of a practiced factorio player to that of a brand new player would carry much signal at all. That means that a company carrying out this type of interview would need to ask candidates to study by playing the game.
You can choose to make X (what's tested for in the interview) a representative cross section of the harder things that you need.

Or don't even try and make X not even intersect with anything you need.

It still puzzles me how many people opt "don't even try".
Robinhood Competes with TikTok and Instagram Not TD Ameritrade or Charles Schwab
This winter break I spent an embarrassing amount of time on Satisfactory on Steam, which is essentially a nicer (and probably easier) modern refresh of Factorio.

While I played, I came to similar conclusions to the article. Building factories in this game is very very similar conceptually to building software. I ran into exactly the same problems that I ran while I build software like:

- If I don't plan ahead enough the scope and layout of the factory, I end up with a spaghetti mess that is very difficult to rectify (technical debt)

- If I plan too much ahead, I overwhelm myself without even starting. The amount over-engineering and over-preparation becomes counterproductive and demoralizing.

- Starting new factories is fun. Maintaining and extending a factory that is starting to show serious design issues is a chore. I always tend to want to scrap the factory and start fresh.

- While designing a factory, modularization is key. You can go with a "monolithic" factory where you provide all possible materials as input, and try to build everything as output. It is very efficient transportation wise, and can centralize all management, but it can and it will become an unmaintainable mess. You can also design factories as "microservices", where each factory is a very compact, clean and scoped. It will only produce nails, or rubber, or copper wire. When you need to increase production of that item, you just duplicate the module (horizontal scaling). It seems fantastic at first, but the issue is now transportation. Dozens of micro-factories have to communicate with themselves to combine and produce more complicated items. The physical distance makes planning transportation a logistic and construction nightmare. So you have to find the right compromise between monolithic and micro-services.

I think I agree with the article that you can extract a lot of information about how good a person can be at software development by the way he plays Factorio/Satisfactory. Not so practical though :)
Canadian engineers don’t make very much (60-120k range is typical) and that’s with a 4 year degree. Neither do technicians, repair people, scientists etc. $120k is just what 18 year olds make doing labour at the very beginning of their career. So the idea that replacing these jobs will ever be politically popular makes no sense to me at all. These people aren’t stupid and they know exactly what they stand to lose if Alberta transfers to renewables. I think they would love to build solar farms if it paid just as well though.

> Canada doesn't have to take such an American view of capitalism, and we often haven't in our history.

Canadian identity is a lot weaker in the west. I don’t think anyone really cares how “central” Canadians feel.
I'd assume their are tradeoffs between capital costs, maintenance costs, and efficiency. If electricity prices are really going negative you can funge against efficiency hard and still come out ahead.

“Google Project Zero maintains public policies around vulnerability publication and attribution”
Would be an accurate headline.
Assigning to Google the act of shutting down counterterrorism is highly misleading and purely for emotive effect.

I would argue that a lot of the "famed agility" and effectiveness of startups is their flat structure and lack of middle management bloat, especially for the devs. As soon as you start splitting the dev teams apart, productivity grinds to a halt and you start hearing phrases like "this team owns that" and other territory marking behavior.
Briefly mentioned in the article, the vaccine is produced inside chicken eggs, a method widely used by Brazil’s Butatan for flu vaccine production. This also removes the need for imported materials, a current bottleneck in Brazil’s coronavac and Oxford vaccine production.
Reproducible builds can go a long way, along with a diverse set of build servers which are automatically compared. Whether you use your personal machine or a CI system there's still the risk of it being compromised (though your personal machine is probably at a little more risk of that since personal machines tend to have a lot more software running on them than CI systems or production machines).
In the abstract sure, but in the concrete and in the way I think through problems its just not the same.

As long as we are playing the game of "what if", there are unending hypothetical abuse scenarios for backdoor access. Malicious actors have a history of exploiting backdoors that are supposedly only for the good guys.

There is also the possibility that law enforcement may not always operate in a responsible or honorable manner.

The issue of police being empowered to stop a person is separate.

I believe there are a lot of details we in the public won't get to know here, but in general Google isn't in the business of choosing to eff up police activity or allied espionage. The whole thing smells to me like either miscommunication or a situation where Google had additional data that made them decide to override the interests of the task force.
