I am trying Swift in the hope of integrating developer speed while with not too terrible performance. Julia would be another interesting choice in this space. Of course, as you get to nanoseconds, any language choice is irrelevant.
Several commenters have brought up garbage collection.

I'm curious. How much heap memory do HFT applications typically allocate in a day?

I'd expect them to be doing most of the work, or at least most of what actually needs low latency, in locally allocated primitives which would be on the stack. If that's the case, you might be able to turn off garbage collection and just stick enough RAM in your computer that it takes a day to fill up with garbage. Once a day, reboot.
This is off tangent, I am surprised that the largest of FAANGM companies aren't trying to muscle into HFT or Quant industries.

It seems right on their wheelhouse: highly technical and makes a lot of money.
You don't want to return the purchase which doesn't work? Or they don't allow you - in this case what the court would say? If it's too bothersome, small claims court supposed to be an easier approach (in USA)?
When it comes to potentially laundering money, the SEC doesn't give you a lot fo time for "orderly shutdown process". You should have gotten your documents in order before the SEC starts knocking on your door.

I don't think so, since it was mostly used for federal agencies and national banks in America.
This is definitely an area of recent improvements, and I don't think modern .net (.net core 3.1 - .net 5) is comparable to older school .net here. Whilst GC isnt quite on JVM level yet (no serious custom GC's afaik), the .net team is clearly paying attention to performance(https://devblogs.microsoft.com/dotnet/performance-improvemen...). As you mention, increased ease of use for structs in the form of Span<T> is having quite significant impact in a lot of common .net libraries, aswell as the recent availability of hardware intrinsics for more performance sensitive tasks. I can certainly say F# has had a pretty decent impact in the finance sector in London and likely elsewhere (not sure about HFT however), mostly as a result of this attention to both performance and developer experience.

Github does block functionality through Iranian IPs, and this is easily verifiable if you know anyone who lives in Iran and can access a website or via an Iranian proxy connection and then attempting to use private repos functionality on personal accounts, with enterprise accounts being entirely blocked.

Personal Gmail accounts are the exception to Google services available in Iran, and some functionality is also blocked by IP - if you live in Iran currently you might know that almost all other Google services and enterprise accounts are outright blocked by IPs too:

As a free speech absolutist, I'm always a little optimistic when I see this sort of thing happen, because it always has the opposite effect than its intent: the censors expect that the things they don't like to disappear completely as if they had never existed, but what ends up happening is that censorship drives further decentralization, which is even harder to censor. This event exposed another single point of failure - its up to the infrastructure to fix that.
All the more disincentive to carry out such evil and heinous acts in the first place.

> The Education Reform Act (1988) requires that: -

> 2. Religious Education should be taught in accordance with an agreed syllabus.

> 4. The agreed syllabus reflects "the fact that the religious traditions in Great Britain are in the main Christian while taking into account the teachings and practices of other principal religions represented within Great Britain". (Education Reform Act 1988, Section 8)

Even if the concepts aren't taught as "truth" it makes things vastly easier for Christian parents to socialize their children in their religion. (Which the U.N. recognizes as a human right.) And it would likely be illegal in the U.S. (Teaching about religion generically would not be, but the provision about the Christian tradition of the UK would likely push it over the line.)

Also: https://en.wikipedia.org/wiki/Collective_worship_in_schools

> Schools with a formal faith designation are required to arrange worship in accordance with their trust deed or, if they have no trust deed, in line with the practices of their designated faith. For schools without a formal faith designation, the majority of the acts of worship should be "of a broadly Christian character". In practical terms, this has been interpreted to mean that 51% of school days each school term must have an act of worship of a broadly Christian character.

Social conservatives in the United States would be thrilled to have laws like the one in the U.K. Obviously a country like the U.K. that's becoming irreligious might not take the legal requirement too seriously. Folks in San Francisco probably wouldn't either. But folks in Iowa would probably take these requirements seriously. Under current U.S. law, schools in Iowa in communities where 80% of people go to Church every week are required to operate like schools in France. (My wife and I once calculated that her little town in northwest Iowa had a church for every 150 people.)

Forcing Iowans to act like the French drives a lot of polarization and resentment. When you hear people complain about the "war on Christmas" that's what they're talking about--stripping away the fact that "the religious traditions in [the United States] are in the main Christian."
Is there any evidence that these types of questions are currently driving the majority of the difference in test scores?
This is a meta comment about articles around the subject. Most of them have been laughably bad and lacking in information. But the 'Diabolical Ironclad' beetle makes for a great attention grabbing headline so every major news outlet has put out an article about this. I love the beetle, but actually finding information on it through most of these articles was difficult.
It used to make a lot of money, there are now enough players that margins are actually relatively thin.
But those amendments didn't exist when it "was written" - if you're an Originalist claiming to interpret the Constitution "as it was written", that excludes amendments. If you change it to "as it is written", sure, that includes them but you lose the claim to be an Originalist given the timestamps on everything after the 12th Amendment since that's 76 years later and I'm reasonably sure none of the framers were alive then.

It's funny you bring that up, because my comment originally even included a bit about how a lot of our current problems can be traced back to Reagan's presidency. He was previously governor of California. Guess when California stopped offering free higher education?

Chicago is in Illinois, which has had a lot of flip-flopping between red and blue governors and has an infamous history of governors going to jail for corruption.

Also I'm not claiming that Democrats haven't done shitty things. Daley bankrupted Chicago and privatized a lot of our public services while running as a Democrat and some of those jailed governors were democrats, but I do think the GOP is more homogeneous in its efforts to break down the government. I mean privatizing everything is a platform they openly campaign on!

If your claim that prosperity has nothing to do with who is in charge were true, we wouldn't see a pattern of blue states outperforming red states economically or a national pattern of economic growth after a democrat president and decline after a republican president.

Coincidentally, I live in Chicago and used to live in California. People love to use both places as punching bags when talking about national problems, despite one being a state and the other a city! It's different types/scales of problems.
If you add -XX:+AlwaysPreTouch to the JVM arguments, the JVM will pre-touch the entirety of the heap at startup time to avoid unpredictable page faults through the life of the application.

I'd imagine other HFT companies may also pay for the Azul JVM which goes even further and comes with a kernel module that the JVM coordinates with for memory allocation. The kernel module pre-reserves x% of system memory at the time it is loaded.
In case it helps: I had some initial problems when using a USB-C -> HDMI cable that seemed to go away when I changed to a USB-C -> DisplayPort cable. Might be worth a shot.

Of course. My point was that we must also consider feasibility--we should absolutely get to a state in which corporations should bear the full cost for their security decisions; however, we probably won't be able to get there overnight.
Identity politics and group thinking squished together loses a dangerous amount of nuance. Identity poltics is how self-identified liberals assert their form of universal subjectivity by splitting the working class racially (read Wilderson, Hartman, Moten and afropessimistic thought and of course Lacan). While Groupthink is naively but generally defined as: " a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome". The distinction thus becomes clear. Identity politics is born of the desire to divide the working classes using the disharmony of racialization causing irrational decision making, while Groupthink has the same ending but with explicitly the opposite desire.
surprised no one's mentioned fairseq, which is probably the easiest way to train and use a transformer model. With huggingface etc you still have to write a bit of code for preprocessing input, training scheduling, batch inference and multi-gpu but fairseq has all that covered with built-in scripts.
When the owners of a husband and wife shop die, with no inheritors, then what?

If the children of the mom and pop shop die, and the children are preschool aged, with no other inheritors or people designated to handle the estate, then what?

Effectively no one says that "every generation must completely pull themselves up from zero".

Do you seriously think the children of working/labor class families, living in rental housing, and with no capital, completely pull themselves up from zero?

Since they don't, neither do the children you hypothesis. So what's the point of your argument other than to tug at our heartstrings about those orphans?

Oh, and if the mom and pop shop is bankrupt, or has little capital, and there isn't family or close friends able and willing to take care of the kids, then who will?

Oh, right, "some state system." So if you are so concerned about these children, perhaps we need better orphanages and better support for the foster system.

Now, how do we fund those improvements?
>I've met many engineers with extraordinary talent who decided to stop making software. They wanted to program computers all their lives. They were born for it. After spending six, eight, ten years in the industry, they quit for good. [...] Something had to have gone wrong for them to abandon their first love.

>But sitting at a mandated retrospective or mindlessly gluing APIs together doesn't put me over the moon. It makes me feel the opposite (whatever the opposite of being over the moon is).

I like Slava Akhmechet essays but this theme of disillusionment doesn't resonate with me.

As background, a relevant wikpedia article when thinking of personal change: End-of-history illusion[1]

I used to think I became disillusioned because the industry was "getting worse". But I changed my mind because it's just too convenient that my peak of creative excitement and wonder about technology just happened to coincide with the "good old days".

My opinion changed when the new iPhone came out in 2007 and I noticed I was not excited about it. How can that be? How can I spend all-nighters messing around with less powerful 8-bit and 16-bit toy computers and not also be obsessed with the idea of playing with the new Apple gadget that's 1000x more powerful?!?

I had to dissect this strange contradiction. I finally had to admit that it's because I simply got older. As another extreme example, as a little boy I used to be excited about hopping on escalators and elevators because they were like fun little amusement rides. But now, they're everyday boring. Escalators didn't change; I changed.

I remember being a teen at a loud rock concert and thinking about no old people being there and being confused as "how can anybody ever stop going to concerts?" Well, it turns out I stopped too. I won't blame disillusionment. Instead, I just got bored of it. I still like live music but not enough to go out of my way to buy expensive tickets and deal with the traffic jam to get back home.

I used read lots of fiction. I don't anymore. Fiction author Philip Roth also stopped reading[2] others' fiction when he got older. I'm sure today's fiction is just fine. But my motivation to read it isn't there anymore. I won't blame the book industry and I'm not disillusioned about fiction. I'm just a different person now.

Is it disillusionment or just getting older? There are confounding variables.

> likewise, disconnecting the hardware inside the device will be error prone and void the warranty.

It’ll still void the warranty, but a drill press, the right place, the right bit and depth should do the job in seconds, no?

Could make it a service of taking smart TVs and dumbing them for $50-$100.
The feedback was the trigger. Basically the point is it’s worth asking whether the downside of giving feedback and having it go poorly is worth it. A much more common experience is to give feedback, and have the job candidate challenge your feedback and/or share a sob story about how they really needed the job. Trade offs and all that.
> He can't really do anything to control what is sent to him

In which case the whole situation is nonsense and moot.

But it appears that some of them are from Biden - "The New York Post cited a purported email from Hunter Biden in August 2017 indicating he was receiving a $10m annual fee from a Chinese billionaire" - in which case the DKIM headers would be a simple check on authenticity, no?
It doesn't fix all location privacy issues, but iOS took a nice step recently of making "precise location" a toggle that users can turn off. For a fitness app, you'd give it a precise location. For weather, knowing what town you're in is probably fine.

FWIW, Starbucks copied its profit sharing (and other ideas) from Sam Walton. Walton's bio pop biz book was widely read (early 90s). Starbucks was considered very progressive for the time (by us "carpet walkers", what the blue collar workers called us office workers). Lot's of happy worker bees.

But at some point, Walmart took a hard turn to the right.

And to my own shame, I didn't understand how anti-labor Starbucks was at the time. There was always grumblings and heresay. It was easy to dismiss as sour grapes and cranks. Then Schultz became a candidate for President and all the knives came out.

Moving forward, I just want what's fair. I don't understand how it's okay for the top of the heap to become billionaires while the minions are making starvation wages. It doesn't have to be 50/50 even split of the spoils. But upgrading from 1/99 to 10/90 or even 20/80 would materially improve the lives of millions of people.

I'm curious how culture wars have impacted your work and family life. I've lived most of my life in large metro areas, so from my perspective "culture wars" are mostly people in far away towns waving fists at us city folk. The actual impact on my life is minimal.

Assuming the code can be made not to allocate much, this approach could probably be made to work, [0] but I imagine it would make more sense to just configure the GC to run once a day.

> I thought we finally are going to discuss about building an alternative to YouTube.

There are plenty of alternatives to Youtube, a bunch of them defunct. Youtube is irrelevant to this conversation; the DMCA takedown would have been equally effective had the copyrighted URLs been from Vimeo or Dailymotion or any other project that dies in a year because its creators don’t understand what makes a video site (and `youtube-dl`) is the community, not the tech behind it.
The slow site even shows up 1 character at a time in view source!
This is why I blog and livecode. Some of it makes money from infoproduct sales, most of it is an excuse to dive into new things (and then infoproductize if I like what I find)

Whether that punishment is jail time or a fine is secondary. The primary question is, should the decedents be punished for a crime they did not commit?

Moreover, where do you draw the line?
Should all the decedents of german families who got their wealth off the back of slave labor by jews also be forced to forfeit their wealth? What about the decedents of families of plantation owners? How do you go about handling that with the institutions provided? What would they be charged with?
> Why do people use the USB tether? The WiFi hotspot always works perfectly, it's an open protocol etc.

My mobile is an Android device, but I believe these reasons all still apply:

* lower power consumption for both devices with wifi off

* significantly lower & more stable ping. i drop from ~44ms with a lot of jitter (a significant number of 120ms pings) to mostly stable <35ms, with a very occasional high ping.

* better-re-sharing. if i am hosting a bunch on a phone, with USB i can bring a mobile travel router with me that has much better range & works with many more users. (it's possible that wifi extender mode may emulate some of this advantage, but it would almost certainly double the jitter problem)
Show HN: Personal CRM: Note taking, the way it should be
> clearly what we need is a way to spoof our location. Just pick a random coordinates each time these apps request it.

A handful of us nerds may run some niche version of Android that allows this, but it is hard to imagine Google allowing random location spoofing on all the phones with its Play Services installed, especially considering that Google itself wants to know your exact location for advertising purposes.
In the case of DVDs, the copyrighted code which decrypted DVDs was being licensed to DVD player companies. The code was not open source, and so stealing the key was itself copyright infringement, and more obviously circumvention of DRM.

In this case we have video which is streaming on the open web, which trivially provides for the user agent to download / cache a copy. The question is not a matter of whether that copy is being redistributed, but that the user agent can watch it in an ad-free space whenever they want. You could probably accomplish the same thing, or nearly so, with a browser plugin.

Which is why I make the comparison to uBlock. uBlock is similarly "playing back the content in an unapproved way" and perhaps you could say it is also a circumvention device.

The whole concept of "user agent" is that software on the user's machine -- that they control -- is rendering remote content in a form and fashion chosen by the user. The HTML provided by a remote server is not a legal contract for how that content must be displayed. It is a semantic description of the content, which the user agent can do with whatever it pleases for display to the user.

As long as no redistribution is occurring, the whole basis of the world-wide web is that a user agent can do whatever it wants to the content, including save a copy on the local machine.

So to me the most interesting question is exactly how youtube-dl becomes/became distinct from a user agent.
In the Expanse books/show they use this all the time and call it "flip and burn". Pretty cool to see what nearly-plausible everyday spaceflight might look like.
>The dollar I earn, I can do as a please with and has already been taxed.

Just chiming in for the 'has already been taxed' thing, as it is often brought up in opposition to taxing inheritance.
No dollar is ever taxed 'finally', it's a continuous process that involves taxes in most steps.
Say you earn a dollar, it gets taxed and 70 cents remain. You go to a store and want to use those 70 cents to buy something. You don't actually get 70 cents worth of product because of sales tax. (See also VAT.)
Microsoft’s Dapr Simplifies Developing and Deploying Microservices
It includes some white people too! No Latino would think for half a second before identifying me as white, but because I'm also Latino, I end up as a "person of color" whenever these statistics are aggregated. And this isn't a minor edge case - something like 10% of the US population is white hispanic.
