> Majority of new websites dont have big performance problem, at least those I visit.

I'd love to visit that alternative universe. I visit many websites each day, and I could count on my fingers the ones without serious performance problems. HN is fortunately one of them.

> In real world, programmers work in chaotic companies with little organization, have short deadlines, have short time to decide which tech, make decision based in what allows them to reach result fast or reliably, are often inexperienced and even experiences seniors don't know everything.

I know that too well, from experience. It's part of the reason I feel the web needs much less features - as typical companies can't be counted on to use them responsibly.
> They are asking questions [...] to see how you handle stress.

I've got a time-saving suggestion - instead of asking questions, measure how long interviewee holds up while being waterboarded. If they can handle that stress, they can handle losing $100 million in 10 seconds, easy.

You're right. I deleted that part of my comment. It was more ranty than I prefer to be. And I had things like Google and Facebook in mind, and 99% of the free games on the App Store or web.
Instead of bailing out the banks, they could easily have simply been put in receivership, with Treasury as the recevier in control. Simply re-capitalize them from the federal reserve, and they don't have to miss a single hour's worth of operation.

Unwinding the mess of CDOs, etc. would have been long and tiresome but, with a little help from a convenient executive order or two perfectly do-able.
How long did it take to get that way? Automatics used to be more trouble prone for a long time.
After Theranos and Magic Leap I've really downgraded the degree to which "huge investments from big incumbents" can be considered a reliable signal for quality.
"Automatic" is way to broad to be correct.

A DCT (Dual Clutch Transmission) like the Porsche PDK is not remotely comparable to a torque converter based transmission. Yet, both are categorized as "automatic".
> I don't want a stupid autoplaying video following me around on the damned page. I don't want Facebook to track me endlessly and mastermind what I see.

Those autoplaying videos and trackers are the reason these pages are there in the first place. All the free content and services on the web has to be paid for somehow, and that is the way.

It's not as simple as:

> Get rid of the 10+ trackers

Sites like Facebook can't just do that, that's how they make money and stay in business.

This is a business-model problem, not a technical problem. If anything, new technology allowed these business models to be slightly less annoying and damaging to the user experience.
In a DOM tree, any live node in the tree needs to keep the entire tree alive.

Which means you either need some sort of garbage collection setup, or reference counting (with cycle collection), or some sort of indirection where you really hold references to a "tree + node" pair and then have to worry about what happens when a node moves from one tree to another. Or something else, other than just having a bunch of objects that all point to each other without any explicit ownership semantics...
I'd love to have an electric drive for first gear, and manual for the other gears.
Well, I'm seeing people doing web apps in Rust and doing operating systems as well. Certainly the Rust community has been all over wasm and rust tooling for that is relatively mature compared to other languages. Precisely because it doesn't need a garbage collector and they don't have to wait for standard solutions for that to ship in the next year or so.

But I agree, languages like Swift and Kotlin are a bit more logical choice as fullstack languages. Both of those are also extending their reach. Particulary, Kotlin code is a very nice upgrade from javascript in terms of expressiveness, tooling, and safety. I'm using it on top of the JVM currently. People are doing Android with it and the native compiler currently under development is explicitly targeted at doing native IOS and Android apps (i.e. not the current java based DEX vm common on Android).
That is interesting. The one electric motorcycle that I heard of that was super fast was the KillaCycle[1]. I think it only had one gear though and a 0-60 mph of 0.97 seconds. The motorcycle nearly killed it's owner[2].

Yeah, my inner gearhead was a bit sad when I sold the manual car and we picked up a Tesla. That said 1-pedal driving is pretty great for curvy roads.

However we acquired an old '81 ford tractor a few years ago so I can wrench on that all I want while still enjoying the EV for daily driving.
Scorched timber can last a hundred years. I have seen a cabin from 1740 made of timber from trees that were scorched in a forest fire but remained alive.
I think this link title is misleading. This isn't a revision of JSON but rather a revision of JSON Schema, a language for writing grammars that can be automatically validated.

JSON itself would not have if statements under this proposal, and indeed the syntax of JSON wouldn't change in any way.
But you can't skip gears like you can in a manual, which matters more when you have 10 speeds reaching mass market.

I hate using manual mode in an automatic. I love driving stick. The fun in driving stick isn't from being able to pick gears.
It's both I think
5G wireless data plans have to be different or it won't make sense to have such high speed.
> Easy to say from the position of thinking you can't lose your license or have the financial means to deal with such a loss.

There's a villainous cycle at work here. Car supremacy produces cities in which you need a car, so that attempts to push back on car supremacy can be credibly opposed on the grounds that they hurt the poor and less advantaged, when of course the very opposite thing is true.
I'm with you on the Miata being a super fun car. That's a great car for a track day.
I find the last statement surprising. Yes, manual transmissions do require the occasional clutch replacement but also have less moving parts. So I would have assumed less maintenance.
Have you tried linking transmission outages from EMS/SCADA to drone images?
Could you build ML for EMS training station to drone images? I worked with Siemens EMS/SCADA and we always needed models of past failures to train operators. Siemens has a microgrid simulator at SFCC, Santa Fe, NM. I am writing python scripts and would like a scikit like set of examples for students to simulate outages in NM, USA. Can you build some examples in Jupyter notebook or Mu Python? How about Sql Server using Microsoft ML?
It is interesting to me that the three areas main areas in America that have become exponentially more expensive are healthcare, construction, and education. It's curious that they have the most government control.
Finally Windows got ready to programming.
Agreed, it's a poor argument.

I once worked for a hardware company which manufactured Set Top Boxes (like TiVO). They could have developed the UI engine in any language, but they chose JavaScript (running on their own custom JS engine). It's surprising how many companies use JavaScript to implement the UI for their hardware devices; to infer that developers only use JS because they don't have a choice is inaccurate.

JavaScript has become a great language. I've programmed in pretty much everything else so I think I'm qualified to say this. In my opinion, if a developer needs to know just two languages today, it's JavaScript and C/C++.

With knowledge of JavaScript and C/C++, you can do anything on any device. A developer who knows JavaScript and C/C++ is usually a pragmatic developer; a good developer.

JavaScript can be evaluated top-level function by top-level function and file-by-file, modulo variable hoisting. You can create situations where everything is blocked, but that's not the norm.

This is pretty cool. Maybe you guys can add English captions to the video, as it's French right now :)
Precious little detail on the batteries themselves. As with all solid state batteries, power is the Achilles heel. I'm skeptical this battery can make provide the 1+ C a car needs to run on the highway, but it's possible it may in the future.

According to [1], the specific energy is ~300 Wh/kg- the best li ion cells are ~275 Wh/kg, but only barely. When the OP article refers to 2-3x capacity improvements (2x on the website), it refers to energy density, or Wh per liter. That's not really considered an important metric except for phones. Unfortunately, the battery has to be over 150 Celcius for the solid electrolyte to work, so don't expect better phone batteries any time soon.

The way this would work is that cars would have a small conventional battery of ~15-30 kWh that could supply acceleration power and preheat the solid state battery. The larger battery would just back it up on long trips. How attractive this is depends 100% on how much power they can crank in the battery, since it isn't that much bigger than a normal battery.

Lots of people think solid state batteries will eventually replace liquid electrolytes, but it's effectively anyone's guess. We've had a lot of trouble finding high-power solid electrolytes for a looong time. The main benefits are safety related right now.

The basic reason is that conventional cathodes are highly oxidizing, so when a liquid electrolyte gets too hot it steals that oxygen and breaks down, causing a runaway reaction. Solid electrolytes and metallic cathodes don't have extra potential energy, so when there's damage to the cell like a short or overtemperature it simply burns itself out. The solid electrolyte is also far more stable and isn't very subject to breakdown from overtemperature or overvoltage.

Very fascinating peek to behind the curtain of cosmetics industry. The "dry water" stuff is in the last pages. Apparently their advertised "powder to cream" cosmetics are popping up in the market. They have a demo video of the stuff, but in that it doesn't seem to work all that well: https://www.youtube.com/watch?v=TmQTOU1KBkw

It didn't cause the root problem but it contributed greatly to it ballooning beyond a handful of investment banks to main street ones.

Interestingly it was also involved in the solution as it allowed some of the mergers that softened the collapse.
I'm guessing the poster is actually proposing changes that would allow the portion of student loan debt above 15k per year to be dischargeable in bankruptcy.
I think this would be a very harmful change to JSON, but fortunately it turns out to be a change to JSON Schema, where it shouldn't really be a problem. (I think it's not a langsec concern because I think the same kinds of parsers should be able to validate data against these grammars with or without the if statement... depending on what kinds of state can be used in the condition, maybe.)

I like your phrasing a lot more but there's a term for this: https://en.wikipedia.org/wiki/Social_desirability_bias

Social desirability bias comes up a lot in UX research and how to engage with users. In theory different methods exacerbate or reduce the effects (e.g. focus groups are highly impacted, individual surveys less so).

Toyota has made a reliable 100k mission for nearly 20 years, but only because they had to build one from scratch. Prior to this American style Chrysler and Borg warner missions were prone to a lot of manufacturing fault related breakdowns. Honda also pioneered the use of metallurgical variances in gears to ensure longevity. Example: high nickel gears in their turbo transmissions.
I recommend any locally owned running shoe store for shoes. Just as much (effective) selection as online and you can walk/run away with shoes faster than buying online. I can't wrap my head around buying this stuff online. The exception being people with odd sized feet. But even then it seems very difficult to get something reasonable.
I think you assume, and rightfully so based on how people discuss this topic, that 'afford' is a black and white numbers game when it comes to mortgages. It's not. I can clearly 'afford' a home mortgage worth the amount I spend in rent each month, but I cannot get a mortgage for that right now. So really the discussion is/was/should be about easing the mortgage qualifications and restrictions. It was not as if people were giving mortgages for million dollar homes to minimum wage workers, and no one would sanely suggest that is a good idea.
I share experiences in a similar vein: a book being cancelled and refunded for being 'undeliverable', a CPU (one of the most important components in a full computer build, rendering it useless) ending up at the wrong facility, new items being sold out until weeks after their release date (Sony WH1000MX3 right now, at least in the UK) while available in other online stores, an item not being what was advertised (Dove soap from a different country with worse ingredients), and worse, them not disclosing this (I happened to check the page myself before picking it up and it had a warning about this). All of this happened in the last month. I cancelled all but the book (which I'm again waiting for now) and got stuff elsewhere with a much better experience. I absolutely do appreciate Amazon when it works, I just wish it wasn't so unreliable.

I'd like to request a source on that. It was my understanding that ShapeShift limited trade sizes, so moving large amounts was difficult, impractical, slow, and exposed to a lot of market value risk.
Exactly this. In Germany the private insurance is actually cheaper than the public one, you can purchase private on the top of public and so on. As a result of a much freer market the prices are much lower.
Why was the situation with the page that does not ask for credentials and does not use https considered unsafe? Is the worry that a man in the middle could change the Login link to a different website?

If they'd taken the same risks that Fannie and Freddie took, they'd have had similar results, and the market may well have gone on functioning as it had before. "Similarly, the total credit losses incurred by the GSEs are about one-fourth those incurred about by private label mortgage securitizations, which are packaged and sold by Wall Street." [0]

The private banks took greater risks and wound up with worse performance.

Yeah, that seems reasonable if you're unable to walk into a store. Even if the sizing is internally consistent it still seems difficult for a first time purchase though.
> ICE efficiency brings that down a decent amount, no?

In terms of power to the wheels, yes. Some of that latent energy can be useful, especially after it's converted into heat.
Yes, I think your programs would be smaller because they are saved as vectors instead of rasters.

> If it's per unit space, it's effectively a bomb.

No, not particularly- the energy stored in an li ion cell is only a small amount of its potential energy. The cathode (eg cobalt oxide) and the organic electrolyte act as an oxidizer and fuel, >10x more energetic than the energy stored in the lithium.

Solid state batteries carry far less energy than a normal battery.

This is completely false, my understanding is there was never a prohibition against women driving in the USA, although maybe at one point in the past it was less common. Also I don't see what this has to do with your earlier point about drunk driving.

Drywall is used in fire safes for that reason. Drywall is made of gypsum, a mineral with water trapped inside its chemical structure. Heat releases that water, which turns into steam and cools the panel. Note that fire-rated drywall is usually glass fiber reinforced, to keep the panel together during a fire.
I have a manual transmission CTS-V and having a manual is a significant performance disadvantage these days. A 10 speed auto transmission will shift much faster than a 6sp manual driven by anyone even a professional, and it has more gears to sit in the sweet spot of motor torque/horsepower. If I buy another fast car it will 100% be an automatic. One thing I like about manual transmissions though is the reliability and maintainability. Problems with automatic transmissions can basically total a higher mileage car.
Funding and/or “serious investors” or even serious people on the board or as advisors means literally nothing. Theranos checked literally all of those boxes, and even got a visit from the Vice President and an award.

And they never even had a product that worked, and what devices they did have were fraudulent.

Having high profile people involved should never have been relevant to the quality of product coming from a company, but now that we are all aware of Theranos is should be absolutely clear to everyone that it is meaningless. It is likewise meaningless to make claims without backing it up with results from at least an independent third party if not making devices available to multiple technically competent reporters.
Could you explain to me how the government control of those things had lead to price increases? Specifically? I hear this a lot but have never heard an explaination and I am genuinely curious of the reasoning
Ah, but you're forgetting clutch plates, rollback arrestors, springs, and seals. The longevity is as expected dependent on driver and style as well

This is such a weird article. It promotes this vision of college being expensive, then undercuts its main argument:

> “The public system in the U.S. is working as well as most systems,” he says. “Parts of the U.S. look like France.”

> Three out of every four American college students attend a school in this public system, which is funded through state and local subsidies, along with students’ tuition dollars and some federal aid.

If 75% of students attend a school in the public system, and the public system is working as well as most systems, aren't we in pretty good shape? Why are we letting the experience of a minority of students drive the conversation here?
Roughly 15-20% during actual driving.

There’s no law of nature that says this is always required, no. But I’m afraid in the situation the Fed found itself in back in 2008, there really was no other option without a much, much more severe recession. Governments had been massively over spending and actively promoting reckless lending, even legally mandating it in some cases with required ratios of low grade mortgages, for years.

I personally know two people that cashed out tens of thousands of pounds here in the UK by remortgaging and spent it. Plenty of consumers were behaving ridiculously recklessly too. It was a crazy time, and businesses need banks. People need banks. Should your bank holding you accounts and mortgage have been allowed to fail? How about the bank financing your employer? How about both at the same time?
