The title of the article and the comments here are conflating several things. We had Peter Lawrey consult at one of my employers, and I've worked on both C++ and Java HFT systems.

We used Chronicle as a high performance messaging system. The secret sauce is just memory mapped files, single threaded processes, and using Java objects as flyweights that just write to the end of the file, or are read from the end of the file. No GC. When taking market data off the wire, or sending messages around a system, that is competitive with C++ and certainly has a fast time to market, and lower defect rate.

The other thing people are conflating is high frequency part: get the market data and... do a complex calculation as fast as possible, and place or pull an order. Placing or pulling orders can be further optimized too.

The fast complex calculation part is where Java isn't as competitive and you run into the GC unless you use object pooling, warming up the JVM and so on. We had a 50-50 system of Java for the bulk of the system, and C++ for the complex algorithms where we mark hot paths and check the assembly on godbolt (thank you Matt Godbolt).
That is arguable, at best it is functional enough so that people can use it, at worst it is not functional for squat and it is mostly dominant because of the incubator attached to it.

In fact I wonder the rate of drop vs new user retention as it is hard to follow a thread, there is no clarity in the headline differentiations... it is really a tough argument to say that it lacks nothing and / or is a good example of function over design...
To be honest it is more harmful than beneficial, these drugs can have a short term side effect of racing thoughts, distorted reality, increased heart rate, paranoia, etc, these effects are well known but people like riding rollercoasters. Long term harmful side effects include onset of schizophrenia, bipolar and psychosis, lung cancer, etc. More people are using drugs like shrooms and weed recreationally than medicinally and at an age where the brain isn’t fully developed. Considered yourself lucky not being exposed to anyone with problems caused by these substances.
There are plenty of apps for development in the App Store. I have a JS IDE called play.js, and a Python one as well.
I didn't try to pass a moral judgment on the issue and I like the socialized system we have, for the most part.

but confronting cost without taxes is trite and tiresome. I'm going to pay north of 150k eur to subsidize healthcare thorough my life, and being in the upper tax brackets (which start at some ridiculously low point) I also have to copay each service on top of already being paying more taxes for it.

and when I see the "but ambulance rides are almost free here in x european country!" and the likes well no, they aren't, it's people that just didn't factor the actual costs in, because it's sunk in other taxes.

I Tried to 'Manifest' Money – Here's How It Went
I would greatly prefer it!

The problem with the USA is not that medicine is not socialised, it's that the price is inflated because of government / insurances plays.

Imagine all the money savednot paying for public officials!
I've lost money as the metropolitan police was completely useless.
They had information, proof, arrested the guy, and then let him go.
He ran away to Dubai and came back operating the same scheme under his second name. Reported it again to the same detective with location of the office and info from newly scammed people I contacted.

They dismissed the case.
I lost only 2k, but other victims (landlords being scammed by a fake agent) lost tens of thousands.
Tried going to court but there is not a physical person with asset in the UK to persecute so I will likely won't get anything. Wasted 500£ more with this.

The government doesn't have any incentive stopping crime, it just relies on the good will of policemen and their limited resources.
If people complain because there is too much crime, they just have one more reason to increase taxes and do nothing.
Paywalled. Couldn't (quickly) find a readable version in the usual archives.
I think it's too simple to say someone only dislikes part of the financial world. Even in the blockchain money space these financial instruments are not positive aspects. The fact that they can be ported into this new space is not a reason to assume they are good.
Who touted the NHS as the best in the world? UK's own politicians? The same guys who under-fund the NHS year on year? The same guys who are trying sabotaging it so they can privatise it?

The NHS is a great institution but the UK government seem hell bent on destroying it while passifying their voters with misleading soundbites about their investment in it.
I got myself my first job as a Python programmer 15 years ago by (among other things) mentioning this blog entry: "Python Is Not Java" [1]

You can become aware on your own by accident. In fact a lot of us do that. Remembering to be aware means there is a muscle memory that does automatic mental state check, there is an intention behind this state check.
Sure, but taxes are spread across the entire population. Insurance sort of kind of theoretically works like this (maybe substitute "time" for "people" that you're spreading the risk over), but the insurance industry are always going to be experts in making sure that no one is coming out ahead on that system. I'd rather have the entire population subsidize a small amount for everyone's health than randomly make a subset of the population destitute for what's often complete random bad luck.

Secondly, if you take a look at non-insured prices for health care in countries with universal health care (for the most part, the "universal" part is limited to residents and visitors still have to pay), the prices are still significantly lower than they are in the U.S. Having a single payer for insurance and strong regulations over health care enable things like price controls, which makes perfect sense in a health care context since it's never really going to work as a free market (emergency care needs to be treated immediately without the ability to "shop around", the care required isn't always evident at intake, doctors refuse to talk or consider financial aspects, etc.)

I agree. Months (or years ago), when influencers started to populate the internet, I often asked myself "What's their website?" after visiting their Instagram/Twitter/YouTube profile. The truth is, they don't need a website anymore.

I am not talking only about teens influencers. Does a restaurant need a website, or a presence on Instagram/Facebook/{delivery app} is enough? I think the later. Sadly we have evolved into this.
This is a bit of a false equivalency -- there aren't many perf benefits in rewriting a C program in asm. The cost you pay for that rewrite is also much greater.

Yes, of course $HIGH_LEVEL_LANG is preferable for many many use cases. In this context, we're discussing "high speed trading systems", for which native implementations are going to be the favorite.
We were avoiding creating issues because of how long it would take to do with JIRA. I had to stop and wait between sentences because the JIRA edit box couldn't keep up with my typing.

Choeger meant that some people are more comfortable living in a busy city than others (alternatively, some people cope with the side-effects of busy cities better than others), choeger didn't deny that cities are advantageous for certain activities and people. I think it's just a semantic issue and there's no real disagreement here.

KYC on outgoing transactions from financial institutions is important to make ransomware payments harder. As much as I like bitcoin, stopping ransoms and extortion is crucial for long term health of world security and finance. I think long term bitcoin gets held in large quantities only by states that can protect it with military power against extortion. I think some more regulation is good for bitcoin to continue to prosper to the next level.

> it is Apple Product Marketing’s job

Actually, Marketing's job is not that.

The job of marketing is to tell half the story, and that is the favorable half.

If marketing is selling a pickup truck, it should tell you that it can carry stuff in the bed, more than before and it will be easy for you to carry it.

They won't say people rarely carry stuff in the bed, that you should really rent a truck when moving a refrigerator or moving your house, and that a sedan is more practical.

They should not open their mouth, unless it is to say you are really a pickup truck person and your dreams are tied up in this pickup.
I know. but that's not an excuse to pass or accept a wrong information ("y only cost x to me in this country") as correct.

Your sentence is brief when no additional words can be removed. Being succinct is important because filler buries your talking points and bores readers into quitting.

I find it harder to understand as well. I do get it but I see that a lot of my fellow non-native speakers will struggle with this kind of writing. Second sentence is way more complex then the whole original paragraph. "Succint", "filler", "buries", "bores into quitting" - whoah. Give me a breath, please! Is this an articatle on how to write good looking text, or easy to understand text? At first glance I though it was supposed to ilustrate the exact opposite of what it tries to ilustrate.

The whole first page is composed of only bullet points and it requires a lot of focus and effort to go through. I had no urge to click to the next page after that introduction. Is it grandiose (had to google that), or do they treat me like an idiot? Bizarre.

It's like reading a list of quotes from famous people. If you would read it aloud after 3 or 4 of these I'm done. Next ones could be a dinner recipe - I might not notice.

When I write to much and too fast (like now I am, sorry!) I like to remind myself how authors write on sites for beginners in a particular language [0][1]. It's clean and doesn't treat me like an idiot.

I don't have access to the article but they'll surely be suing on GDPR grounds, for unpermissioned use of personal data, not the copyright (which, I agree, they probably won't hold).

It's akin to an employer now tracking 24/7 whether you are sat at your home office desk (in my view: this shouldn't be allowed, with or without permission).
Firstly, this is not 'advertised' - this is not a material average apple consumer reads.

Western expats in China have been a thing for decades. Usually theses are internal transfers within the same (Western) company.

But now with the growth of Chinese companies, this becomes an 'adventure' not so different than accepting a job abroad, wherever that might be.
Certainly the "side loading" option would increase complexity, or it would make a large group of iPad users load applications, mess up their iPad or expose their data, and then complain to Apple. The iPad's strength is that it's hard to break its functionality.

Not really. The "Software Engineering at Google" book[1] has a whole chapter on it with screenshots.

What's your point? The documentary doesn't really touch on basically any of the points that this comment refers to as it ends around 1990.
I liked the documentary though, because I was also born in the 90s so I mostly saw the ugly part of Diego.
If you're using "background GC" (new default), they are doing GC in multiple steps, by running part of GC work in another thread - there are still parts which require suspension of managed threads. Here's some more insight:

It was generally considered bad because it (and other programs like it) often generated bad markup with a lot of overhead, spurious tags and what you might call "bloat". While there's certainly bloat today too it was a different experience on dialup, especially in the early days when you paid not only for the phone call but were also often charged a steep hourly rate by the ISP.

There was also quite a bit of elitism and protectionism about it, because for a while a lot of people were actually more or less making a living from writing nothing but plain HTML. If anyone can make a web page, what good are HTML skills? Quickly, let's find something bad about it and save our jobs!

Yeah, honestly, even $2,000 is absolutely outrageous for a procedure like this. This pretty clearly to me would have a pretty disastrous effect on preventative medicine - if each doctor's visit has the potential to cost you thousands, of course you're going to reserve it for emergencies only.
It is shocking that people still talk about America as this place with amazing freedom. That has simply not been true in a long time. Especially looking at the disaster that is American democracy today, it is hard to grasp how people can still cling to this idea.

Among all developed countries I have visited and lived in America has always felt most like a police state to me. Cops are aggressive, overzealous and tend to show zero tolerance. In general anybody with some authority are kind of scary in the US. Just look at immigration in the US. You will be hard pressed to find immigration in other developed countries behaving in this manner.

What I notice most interacting with American at authorities are all the threats. Pretty much any document you sign elaborate quite a lot on the dire consequences of filling it out wrong.

And as one can see online and I have experience myself, the Us is a country in perpetual paranoia. Cops get called all the time for nothing. And they abide. There is not any issue small enough for them to not show up. And they are not nice. They act like police state police. You can look at videos online of police arrests and dealing with different situations. American police tend to escalate and be very brutal. Slamming people to the ground. Beating them up. Pointing guns and yelling. Handcuffing even small kids. A ridiculous practice seen from the perspective of other actually free countries.

No, the US is an embarrassment to liberal democracy. It makes the rest of us living in democracies look bad.
Yes, the Apple equivalent of a Surface.
The problem I see is the assumption of a uniform distribution.

The problem spaces I normally deal with involve clumps of data, not really uniform except within each clump.
Again, I absolutely understand that desire. I am arguing that it's not possible to do that in iPadOS without making it unusable - or at least severely worse - for non-power users.

Come to think of it, the iPad Pro line was a bad strategic mistake.
Here's another perspective - The ipad in my developer eyes is a powerful computer. It can do much more than just people use it mostly for - reading books and gaming. In fact, I'm using an iPad air right now and feel held back by the limitations of iOS imposed on me as a developer. I can't write code on an iPad (reliably). The machine itself is capable, so is the OS, but the narrow use cases Apple wants to portray it for gets in my way.

In fact, I was so frustrated, I was even looking at some alternatives. The only thing that gets closest to what I want is a Surface Go - a full fledged windows computer that can literally do everything I want (SSH, Coding, etc) I would switch instantly in a heart beat. But, the longer term consequences of an ecosystem switch pull me back. I'm invested in the Apple ecosystem heavily at this point and would much rather have something from Apple that also covers developers' use cases. I'm sure even Apple employees doing programming would like to see something like that. But, Apple needs to listen to make it happen. And they don't. Hence, such posts. At least, that's what I can infer.

P.S - I'm far from an Apple "fanboy". I'm a developer first and use whatever helps me achieve my end goal.
Gitlab CE would be perfect, then, since it's free. If you're on a tight budget it actually seems like one of the best options available.
This. The most underrated comment. :-)
>but you'd be surprised how many people don't know their own feelings.

Probably grew up in abusive-ish households where the parents didn't respect the child's emotions. I only found out I have severe anxiety when I was like 27 years old. It took me a year of having full blown panic attacks to realize what it was. I thought I was just being "weak", because that's what I was taught my whole life.
> As far as I understand China is not a very immigrant friendly country.

China is very flexible.

There may be difficulties in getting citizenship (which is another issue, really), but for work visas to foreign talents, which are sponsored by local companies, this is simply a matter of applying in order to get one.
> as if the only desirable world is one in which we all experience immortal bliss until the heat death of the universe.

This is a very fast step beyond this point, which I think does not do it justice. This end goal is worthwhile and logical and it is not reasonable to pretend it somehow isn't the only desirable world.
Hi Rob, thank you so much for getting in touch! I read through the KEP. I'll keep an eye on it to see how it unfolds, would be thrilled to help out.

end users don't know how to give this feedback

in the case of EMS, it sounds like they could recognize it, but probably didn't report it back to the company. Why bother? They have used their product; they see it as "good enough".

But very often, end users get frustrated by things like input latency, and can't express what is making them frustrated in specific terms. So they tell their IT department that "it's slow", and IT goes back and starts hammering on the __ team (networking, server farm, whatever).

It's remarkably powerful if you can help you users develop vocabulary to recognize and report what they experience. (it's also flipping hard)

Louder please - this is applicable far beyond cryptocurrency.
A very good example actually. As a developer (in the construction sense) you wouldn't use a mountain climbing hand drill to build a house. You would have specialized electric drills, and standalone hammer (or several) since charging and weight isn't really an issue there.

That hand drill is exactly the equivalent of shoehorning any IDE onto an iPad, as in, doing the best within severe constraints.
maybe with less than 8 people in a room though

And that is one of the many reasons why US healthcare is so expensive. I live in Sweden now, and many of the 'minor' things a doctor would handle in US is handled by nurses here. Personally I've never felt this to be a problem at all, but I know many people in the US feel very uncomfortable about that idea.
UTF-8 has an even stronger guarantee: If a byte sequence at any position in a UTF-8 string matches the byte sequence of a UTF-8 encoding of a Unicode code point then that part of the string represents that code point. This means you cannot just use standard C functions like strchr with UTF-8 strings and ASCII characters but you can alos use e.g. strstr to find UTF-8 substrings in UTF-8 strings.
You are right that you also have to include taxes, but you also have to account for the fact that taxes are dependent on income and coverage is always guaranteed.
So it is not the same as paying for a service. It is something else.
