How is it different to any other competition between companies, what makes this one specifically pointless? Your idea will just put more money in the pocket of the bank traders rather than spreading the wealth to all the IT engineers and equipment manufacturers which supply this slight advantage, what's wrong with that?

There are (at least) two different things people mean when talking about terminal performance. What's measured above is latency, i. e. the time from keypress to the letter appearing on screen. I must say I rarely actively notice any delay, except when the system is slow or I'm working remotely and the delay is above, say, 1/3 of a second. I was, however, surprised by how notable no delay can be if you ever get to experience it. In my case, this was typing in an UEFI shell. I can't measure the delay there, and it's surprising that the difference from 5.0ms to, at best, 0ms is noticeable at all.

There is also throughout. Some programs have real problems rendering large amounts of output, i. e. when tail'ling logs. This was a significant problem with Hyper, for example, but they have changed the backend library and it's fine now. I believe the reason here is usually a lack of bouncing, i. e. rendering for every new character even if they arrive faster than the refresh cycle.

It's not entirely unreasonable that rendering takes some time. Terminals have evolved and, as but one example, character widths now vary even when using monospaced fonts (non-ascii characters, emojis, whatever). Then, there are fancy additions like ligatures, transparency effects, etc.

It's a distinction without a difference. It's not like they lose money by offering the delivery service, so they've found some model where delivering food is profitable, it's just that the model involves a tight coupling with the food producer.

It might be more accurate to say that food delivery as a separate business from producing it is hard to profit on.

I think it’s not 500 deletes, but it’s certainly not great. There is definitely an index. If you can repro this, you should file a bug for it, I’ve noticed it being slow too, but couldn’t repro it recently. If you file a bug for this, you can CC me (tcsc at mozilla dot com).
This doesn't respond to my argument: if your users knew that your sense of ethics is that attacking their private browsing data to buy mosquito nets is justified, they wouldn't be your users. (That small subset of your users that thinks mosquito nets are a good use of money would either donate directly and ignore your extension, or voluntarily participate in a scheme to turn ad views into mosquito nets such that you gain no additional mosquito nets by selling.) So whether or not you are willing to sell, in a market with perfect information, the value of your extension would be close to zero.

Therefore the only way that your extension has value is if you are intentionally withholding information from users about your willingness to sell. Which, even without getting into the ethics of deceiving your users, is at odds with the generally-accepted sense of the word "value" in economics. If a company is withholding information about it doing poorly and has a higher stock price than it would if it didn't, you generally say the company is "overvalued," that people are erring in attributing that value to it, not that it increased its actual value.
It's odd, in that I never really thought about Caviar as a competitor to DoorDash -- but that's because I know them mostly as the company that bought Zesty (just before Caviar itself was bought by Square). Zesty specializes in catered group meal delivery. The company I'm at now uses Zesty once a week; the company I was at before used them five days a week, and the company before that used a competitor (ZeroCater, I think) five days a week.

As far as I know, DoorDash wasn't in that space before; I wonder if that's part of the reason for the acquisition. (The alternative is that they may not be interested in that side of the business at all and shut it down.)

>Would you prefer that prices update only once a day?

Obviously you are being hyperbolic, but some people have proposed literally laying excess cable to slow down the speed of automatic trades, which can be highly volatile. That's not damaging market makers at all. It's smoothing out the supply and demand to prevent micro-crashes and other arbitrage.

Despite having a smaller extension ecosystem, Apple seems to have the right idea: Safari extensions (and soon even system extensions) are discovered and delivered via the App Store like any other app, and their developers can charge for them like any other app.

Bummer that you're being down voted as it is a legitimate concern. Someone will eventually have to decide at what point a website has to be accessible, ie minimum views, minimum ad revenue or goods sold, etc.

IMO, extension authors should not be allowed to submit minified code alone to the extension stores for review. (Options include having standard minifiers that the extension stores run themselves, allowing extension authors to provide a .travis.yml or something where the sources to the build pipeline are themselves auditable, etc.) I can see an argument for withholding source from end users for things like paid extensions or clients to proprietary services (to be clear, I wouldn't agree with such arguments but I can see them), but I don't see the argument for withholding source from the browser manufacturers themselves.

Put another way, if the browser manufacturers run an extension store, they are (or ought to, at least) endorse the extensions in that store as reasonable to install. I don't see how they can do that without source. I think they could sort of make that endorsement without proactive auditing if they can remove extensions they discover are malicious, but if they can't even human-audit the source in response to a report of problems, I don't think there's any way they can responsibly offer extensions to their users.

> To approach a dog politely, instead of walking straight towards the dog in our very human direct way, you could walk in a slight curve. On approach, turning your shoulder away ever so slightly can put a dog at ease and is polite.

This is an interesting suggestion given that in my experience, dogs do not exhibit curving towards humans. Dogs that make eye contact with me, usually make a beeline towards me regardless of their leash condition. It seems like dogs have learned that humans do not curve and approach directly.
This is probably similar tho how dogs can read human facial expressions even better than they can read dog expressions.

I would not be surprised if most dogs are socialized to humans (vs they need to be socialized with other dogs)

Not a link to a pdf, despite the HN title.

I wouldn't say it's meaningless. These types of technologies are usually arbitraged out; ending up with a few large players that are squeezing out a return.

It means high frequency volatility is taken out of the equation for the rest of us -- Which generally is a benefit for other players in the market.

FX has (effectively) been that way for a long time.
As always, some profit is to be made from some trading practice - the market removes it within a few years of "mass discovery". All working as intended.

Trying to be non-snarky here: How does it help someone who doesn't need any of today's typical accessibility features?
I think making all startup web applications more accessible would be a great improvement for everyone, especially techies. A webpage that’s accessible is also easier to script or remix.

Why would anyone oppose this? Is the only way to get your startup off the ground to walk over visually impaired people? Restaurants have razor thin margins too but I’ve never heard of any restaurant looking to save a buck by limiting wheelchair access.
What claims do you see him putting forth "without any real evidence"? I don't see how it's at all off base to assume China might take a military interest in AI labs Google establishes in Beijing.

EDIT: Ah, I see that Thiel said elsewhere that China already carried out espionage inside Google and hasn't backed this up. That claim is absent from this op-ed but it may be CYA for those comments on his part.
Having struggled with it, here's the most charitable reason I can give:

First, remember that the blind have always been able to order pizza by just calling in with a phone. Domino's is serving the blind in that sense.

The case here is about them being unwilling to provide an online-only discount to the blind. So why are they paying so much to defend, specifically, a blind-inaccessible, online-only discount?

They offer an online discount, I think, because they get so much more valuable data from it. Like most websites, sadly, their site loads you down with a torrent of trackers.

What does that have to do with being accessible? Well, if the blind can easily navigate to the important parts of a site, so can their screen-reader ... and so can any program. Then, anyone, not just the blind, can bypass all the crap on their site when ordering, and even shut out the trackers.

Where's the flaw in my logic?

tl;dr: Anything that helps the blind navigate their site also helps you bypass tracking, and makes an online-only discount unprofitable.

I've noticed there are SO many of these "coding interview prep" courses lately. Like, obviously it's a hot job market, but there's just so many and of a certain vibe that it seems like some are selling a dream.

There's a common narrative too, that it's all about algorithm question prep and it's a "game" you can win. One youtuber who recently landed a ~$275K TC gig said it's not about being "intelligent" it's about practice and rapid pattern recognition (he also was pitching his own coding interview prep course). Said he forgot half of it after getting the job.

This could all be true but this narrative is coming from sources that have a financial interest in making you believe that. What do you think HN? I mean I know algorithm prep is an important part of the interview but.. there's just something sketch about all these outfits I can't quite put my finger on.

(I also wonder if the people who get hired based on prep vs. aptitude then have a kind of survivor bias and hire others who are strong on this limited range of pattern recognition... could it be a problem for the industry?)

Adding to this, HFT is a product of rule 612 of Reg NMS (the sub-penny rule). Markets are not allowed to show quotes in increments of less than $0.01 for most names. Since traders cannot compete on price, they have been forced to compete exclusively on speed.

The impact of such regulation was tested by the SEC recently with the 'tick size' program. Instead of reducing the minimum increment, some names saw it increased to $0.05. The hope was to increase liquidity while decreasing volatility in these names. In fact, those names experienced decreased liquidity with no decrease in volatility.

HFT is a result of regulation.

People that are very serious about it use ASICs/FPGAs. I'm sure Goldman does too.

For slightly slower stuff it's the garbage collector and OS scheduling that's the problem (as both can unpredictably inject many milliseconds pauses). No GC and good usage of low level kernel primitives is the game.
Late 1990's Apple was basically mired in technical debt. The original classic Mac OS was over a decade old and on very shaky foundations. No memory protection, cooperative multitasking (until OS 8, I think?), etc. Their own internal OS projects (Copeland, Taligent) were never completed.

NextStep was like night and day. It breathed new life into Apple.
I actually think the early-access model is similar in spirit if players can get a decent cut in price (say at least 25% off).
Surely there's an extension for that?
Most importantly TLS 1.3 _always_ starts by the two parties setting up a secure encrypted connection, and only then is any effort expended on trying to figure out who anybody is

I wonder what the motivation behind that was --- I'm no cryptographer, but setting up what is effectively an anonymous (EC)DH session first seems to provide no extra protection from an active MITM because it's unauthenticated. The only other protocol I've seen do this is obfuscated BitTorrent, using a deliberately short keylength and RC4, where the goal was not protection from MITM but to resist traffic analysis and blocking by making essentially all of the traffic look completely random. Meanwhile, TLS 1.3 still retains the plaintext record headers and framing from previous versions.

(One thing that I've always wondered about and never gotten a good answer is the fact that as far back as SSL 2.0, and presumably 1.0, there seemed to be no attempt to make the whole protocol encrypted, but instead the messages were very identifiable. Why not? One would think that a protocol designed to conceal data should itself be hard to distinguish from random noise.)
> Consider, for example, the various congressional investigations of Hilary Clinton in 2014/2015. If everybody was guilty of some crime(s) punishable by jail time, it would follow that some of those overly brought criminal statues would have come up in those proceedings, considering there were any number of high-powered lawyers tasked with finding anything against her that would stick.

There are a lot of reasons to expect it not to be easy in that specific case.

The first is that she's a career politician and a lawyer married to a lawyer. That removes most of the low hanging fruit. She would be more aware of more of the laws that are easy to avoid breaking if you know they exist but most people break all the time only because they don't. Then she's not going to let herself be questioned without consulting legal counsel, which makes it a lot less likely they can prove something by getting her to admit to it.

On top of that, there are two kinds of laws that people break all the time, and neither of them are really suited for political cases like this.

The first is the really obscure laws or unusual circumstances. You have a pocket knife, you walk under an overpass which is technically state owned property, there is a law in that state prohibiting possession of a weapon on state property, etc. Or you have an unusual fruit in your bag on when you cross a border. Everybody breaks laws like this unintentionally, but these are the ones where (absent a surveillance state) it's a lot easier to choose an overpass and find a person walking under it than to choose a person and try to find evidence of a violation like this, and charging a prominent politician with something like that would immediately lead to mockery and claims of a politically-motivated prosecution.

The other is the ultra-broad laws they can charge anybody with (e.g. CFAA) because technically everyone violates them regularly. The problem there isn't finding violations, it's that the prosecutors won't want to risk using those laws in cases like that, because they find them too valuable in general and it's prominent cases like that which lead to them being narrowed by judges. The power of those laws for prosecutors is that you might be able to beat the charge, but only by spending millions on lawyers, which causes ordinary people to plead guilty. That doesn't work against someone like Hillary Clinton because she'll spend the millions on lawyers -- and potentially cost prosecutors future use of that law against the proles.

> The Clinton example may be imperfect because of partisanship, but I can't currently think of any other widely-known case where prosecutors were trying to "throw the book" at someone.

Think of cases where the accused isn't rich or politically connected, e.g.:

https://en.wikipedia.org/wiki/United_States_v._Manning

In particular, look at all the ancillary charges they tack on to make sure something sticks and consume defense resources. That's really common and is typically even worse in less high profile cases where there is less scrutiny of their absurdity.
