I am sure, 5us was measured on the switch, not on the server.

5us is actually quite slow.

This is from 2014, around the time I worked on this project:

https://stackoverflow.com/questions/17256040/how-fast-is-sta...

They cite "750 to 800 nanoseconds" wire to wire latency and that their next platform is going to be even faster.

They were using FPGA and yes, FPGA is faster, but not as much faster as many people would think.

First, market events come in isolation. There are no concurrent messages. WSE guarantees 1/10000th of a secend between each message. So you have your entire machine dedicated to executing the order.

FPGAs are usually used to run multiple copies of same net to speed up a simple problem but that is not the case here.

Second, FPGAs are usually used as a shortcut to optimize the execution of the problem. With FPGA you say "rather than trying to solve this problem with generic instructions that add a lot of delays I will just design dedicated net that will not be bothered by the generic baggage".

So in generic assembly you may want to write a branch and the branch predictor may go the wrong way and that costs. On FPGA you design your net and so you just go straight to the point.

But it doesn't mean you can't design normal code to be fast. You just need to be aware of actual cost of every single instruction of the critical path.

And third, FPGAs are clocked slower. What this means you have to do a lot per clock cycle on FPGA just to be on par with x86 core.

That application I worked on it was not intended as HFT. 5 us was an arbitrary goal we wanted to reach knowing full well that it is way behind HFT-ers.
> Hey HN reader. Get rid of plastic from your life. Doing future you a favor.

No. We need to help the working class become system -literate, and then demand systemic change together. This is not the 'individual choice' problem these call the actions make them out to be. We need to fully map and understand the undemocratic black box systems and their obfuscated rules that we live under.

Governments and firms could end plastic packaging/usage today, yet don't because of perverse incentives that send the same foods in the opposite direction which means food has to stay fresh for much longer while traveling much too far.

"Many urbanised people have lost touch with the sources of their food, and may not realize that the distance their food travels has been steadily increasing. In the US, the average pound of food now travels 1,500 miles before it reaches the dinner table, and the distance continues to grow.

Much of this transport is needless: every day, identical commodities pass in opposite directions, criss-crossing the globe. The ‘logic’ of the global economy leads the US and other nations to import hundreds of thousands of tons of staple foods each year, while simultaneously exporting roughly the same amount. In an era of dwindling fossil fuel reserves and rising CO2 emissions, this is both senseless and wasteful. But it is a trend that is accelerating as governments systematically promote a single, globalized food system."

- Helena Norberg Hodge [1]

A horrible example of this is when a country like Ethiopia, that's been neo-colonized by global north capitalists, exports rice and other foods while the Ethiopian working class people are starving and pushed into slums in cities (away from their land). [2]

The video by Annie Dillard called the Story of Stuff [3] is still a fantastic summary of this (as are her other videos).

Wow cute response.
In my country, it's legal and widely used, so much so the government entity that is supposed to look out for the workers provides a template for employers with suggested questions you should ask which even go as far as the person's reason given for leaving, their work performance and if you would re-hire them.

> In the very least, the battery mass is responsible for an effective drop in energy efficiency of around 30% just to cart someone around.

It's not nearly as simple as that because electric cars have regenerative braking, and because the energy doesn't all go into acceleration. A lot (probably most, depending on how you drive) goes into wind/rolling resistance at a constant speed and that doesn't depend much on mass.
Yes! Of course the comments here will skew towards people who do, but maybe that’s motivating :-)

I don’t donate crazy much, a few streaming services worth, split across many projects. I’m not going to single handedly fund any project, but if everyone gives that amount, a lot of worries are solved.

The bill doesn’t yet exist. It’s currently being negotiated because of the slim majority Democrats have in the US it needs centrists and liberal factions of the party to agree, which you’d think would be easy… but in a strange political way they’re trying to throwing everything into one bill (childcare/ healthcare/ environment ).
Pines shade the ground throughout the whole year, densely planted ones especially. Leave trees, like beeches and oaks, loose their foliage in autumn, thus in early spring other plants get enough light on the ground to flourish, before the trees produce their leaves again.

From my understanding it is almost certainly a lost cause at this point. I am not a scientist so I do not know for certain, but from what I have read at this stage even if we halt greenhouse gas emissions to zero it still won't be enough to stop the drastic changes to the Earth caused by high CO2 levels. We would have to actively removing CO2 to have any sort of chance at preventing the worse problems associated with Global Warming. Not to mention the amount of other pollutants we have released such as plastic/ microplastic that have been and continue to, disturb the ecosystem of our planet.
I can make at least three people IRL that do this regularly.

My business has had huge success with promoted listings on eBay. People will gladly pay 20% more for a sponsored item rather than scroll down literally one inch to get better organic results.

Even if these people are a tiny minority population-wise, they make up a disproportionate percentage of people that waste money on frivolous or overpriced goods.
Sure, but the same goes for the M1. It's peak power draw much greater than the 10W figure Apple used. I believe arstechnica measured it at about 28W after removing the platform base power cost.

The M1 is a great chip, but it's not some impossible unicorn that no one else can ever match.
It is clear to me that we are in a holding pattern for web components to become the norm and for component frameworks to become decoupled from application frameworks, so I have no idea what I will be using in 5 years.

So, we'll arrive to something similar to where we are with JavaScript and jQuery, where the latter is less relevant now that JavaScript is appreciably better? Meaning, that with web components the norm, we might arrive to less need for frameworks like React or Vue?

(I might be misunderstanding due to the sleep deprivation, so apologies if what I write comes across as gibberish.)

I have a bunch of links to ML material for either APL or J. I don't know of any particular library for J. J is interpreted, so it is not as fast as other implementations. I am mainly using it to experiment on concepts and teach myself more ML in J because of the iterative nature of the REPL, and the succinct code. I can keep what's going on in my head, and glance at less than 100 lines, usually 15 lines, of code to refresh it.

There is a series of videos of learning neural networks in APL cited by others here on this thread.

> Americans (and Australians) will never accept any changes that negatively impact their lives or wallets. Especially when the consequences of climate change are not clear and present. As democracies, we will simply vote out any government that asks us to change our ways

I'm at a loss for words here. The most lauded Australian prime minister of the last 30 years is the one that banned firearms, dragged Australia into the Middle East, started offshore detention and introduced a value-added tax on everything from drinks to tampons. People have literally been elected on promises of destroying internet infrastructure.

The problem Australia has is exclusively to do with every single political group (including the Greens) being anti-environmental and peddling conspiracy theories about things like nuclear and hydroelectric. It has nothing to do with what Australians will or won't accept -- Australia has arguably the world's most docile, suggestible population. It has everything to do with political incompetence and an extreme, unhinged focus on being electable.

> I think Covid19 demonstrates how resistant people are to change, and that they are not willing to make sacrifices for the greater good.

Australians have endured some of the longest, strictest lockdowns, and are on track to have one of the world's highest vaccination rates.

I'm really not sure why you seem to be pinning this on the population.
A mature forest doesn't remove much CO2 from the atmosphere. A growing one does. Depending on what you do with the felled lumber, it could be much better for the environment to chop down a forest and plant a new one.
Like using more nuclear power ?
I don't want to downplay such efforts; all good to you being ahead of the curve.

That being said: average people work 8 hours a day, have a family, and other responsibilities. Stuff like this takes a considerable amount of time, money, and effort. Which is why I believe it should be dealt with top-down such as a recent addition of small plastic bottles to the container-deposit legislation.

I have a different minor example on how to add good weight to the problem: go outside with part of your family (or whole) and gather plastic on the streets. Kids like the fresh air, walk, and small tasks they get. It makes your neighborhood look less impoverished/more proper on top of that. Here in my city, they give the sticks to grab the plastic for free. And I wouldn't call it a progressive city (VVD). If you used the stick for one hour they got the investment back (7,50 EUR last time I checked).
Honestly Catholicism doesn't have a stellar history with smart people in general. Or kids, for that matter.

When I mention anti-intellectualism in Catholic doctrine, people often retort "Well, St. Augustine...". Guys, if you need to go back 1,700 years for a counter-example your argument might not be on the firmest ground.

Yes, there are many smart Catholics. I'm not saying Catholics are lesser people. This isn't bait, or flaming Catholics. I'm adding to the guy above's pet theory, which at first glance looks pretty compelling, when you add up the effect of those very real and well documented trends over generations.
The big problem with landmines is they are not generally cleaned up after the war, leaving them around for innocents to trigger and get hurt, maimed, or killed.

The interesting thing about iAd was that it failed because Apple refused to sell out everyone's privacy.

>According to advertisers, both Apple and Amazon have levels of detail about customers that would be extremely attractive to ad agencies, but refuse to hand it over, citing privacy concerns.

In Apple's case, the sheer volume of information it has about its users frustrates advertisers because they can't access it. One unnamed source said that in terms of attractiveness to potential advertisers, Apple is "the best-looking girl at the party, forced to wear a bag over her head."

This is probably the best example ever that it's easier to ask forgiveness than permission.
A simple tax on fossil fuels raising the price of fuel to $10 is $20 per gallon should do nicely. If not, keep going up.

I unfortunately just spent some time on Twitter reading about this debacle, and the number of crypto bros attacking anyone remotely critical of DeFi was astounding. They're all throwing around the term 'TradFi' as a pejorative — it's so weird.
There's more than one plan. The one I'm on is $10/GB until you use 6 GB (or $60). You're right though that they slow down after 15 GB (not Gb) but I've never come anywhere near that.

Australia and America definitely differed in the case of COVID-19.

There was huge support for lockdown and restrictions here for a long time, and only just in the last few weeks is compliance becoming an issue in Melbourne (but not so much elsewhere). Turns out a year of social restrictions causes fatigue.
This is because "peer-to-peer digital cash" is incompatible with features that consumers definitely want, such as, reversibility, legal protection and customer support.
So you’re saying unions don’t represent labor?
I read a few pieces on tax advise and they all said crypto currencies aren't considered money in the sense of taxes. Which is kinda strange, but seems to be the downside of a government not allowing crypto to be legal tender.
Nuclear power can't come online fast enough. We shouldn't needlessly decommission plants like Germany did.

There's an opportunity cost here - we need to make "power plant factories" rather than just "power plants". So if we could make green energy factories and nuke plant factories, that would be better than making one off nuke plants that take so long to get approved.
Uh, what?

Furthermore, Google will "dynamically" assemble an advert based on the current search to 'optimise' click-though (and they recently sent a mail out making it clear this will be the only type of text ad going forward)

They think they're optimising "click through" rate.

But what they're really doing is using heuristics to find the advert that's most likely to be confused with the top search result.

Either way, the ad platform wins.

And companies pay their protection money.
I am pretty sure that in US usual fashion, the bill include other kind of amendment that have no relation with climate change and could have adverse effect on those company business, but yeah let's simplify narrative and say that these company are pro climate change.

I am far from being a FAANG cheerleader but I feel quite skeptical that it is as simple as the guardian is depicting it, if only because it is a britain based news outlet.

I've worked in banking and my ex worked for Facebook, and I genuinely don't see the comparison beyond rather inaccurate tropes. Bankers aren't tearing apart society and sowing division like Facebook is.
Ignoring your questionable use of the word achievement, Guns, Germs and Steel by Jared Diamond explains the massive bulk of this. It might not be written for academics, and may jump to a conclusion or two, but it's pretty damn convincing all the same.

In any case, discounting the geographic luck that Europe has benefited from is unwise. And a lil bit racist.

“Lost cause” makes it seem as if nothing we can do will help. But that isn’t true. There is a lot we could do that will make the world of 2100 and 2200 better than if we continue doing things as we’ve done them.

The real problem is that politicians are unwilling to act. But there’s no shortage of action we could take.

Diophhntus certainly is the father of Algebra, but he only laid a concrete foundation that al-Khwarizmi solidified into a distinct field and built into the castle its become today. A lot more than that simple foundation, but you're point is taken.
A more accurate statement would be that Facebook/Google do sell your info for profit and Apple haven’t yet (at least to the same degree).

Track records are important.
If you’re willing to take input on stdin, you can rewrite it without >>=:

main = interact number
where
number = lines . zipWith addNumber [0..] . unlines
addNumber n l = show n ++ " " ++ l

My point is that the logic itself does not require the idea of monadic sequencing — it’s relevant only for the minimal amount of surrounding IO.
In practice I'd say that a lot of priests did father children. Made of flesh and blood...
Takeaway: we aren't changing jobs enough.

The OP suggests some "decision" was made so employees compensation is increased minimally, unless you change jobs.

The only decisions that was made was by complacent individuals, which are apparently also here in the HN comments.

Change jobs more frequently. If we all do that, the compensation increases from performance and job-change will converge.
> if the past year of climate catastrophes has shown us anything

There was nothing unusual. Whatever storm or heatwave or drought you might refer to, there will be significant historical precedent. Whatever it is, often history will have recorded a much worse one back before humans had added much CO2 to the atmosphere.

> We need drastic measures.

I'm much more worried about people saying things like this than I am about the climate.
This comment is just plain dumb. Sure the things you mention all help in losing weight.

But going by the fact that many obese people want to lose weight but still cannot do the things you mention shows that they are not easy.

I know it feels good to be judgemental and to sound tough, but you’re helping exactly no one with that attitude.
One of the particularly notable things about libraries and catalogues is how much does change.

There are on the order of 1--5 million new books published in English each year (about 300k as "traditional" publications, fairly constant level since the 1950s), the largest collections have tens of millions of volumes, the cataloguing technology and standards have changed tremendously over the past 50 years, and the role and usage of libraries themselves is under constant flux. At the same time, budget and staffs are small relative to the total record store.

The challenge of organising, classifying, and making accessible all human knowledge has occupied numerous great minds for centuries. We're familiar with Google's take, marrying full-text search with a document-ranking model. That worked relatively well for about 20 years. It's now showing extreme signs of stress.

At the same time, much of the past (and present) traditionally-published media is finding its way online, whether the original publishers and established libraries like it or not.

LibGen and SciHub may have far more to say about the future of cataloguing standards than the OCLC.
I’ve listened to quite a bit of his podcast (I’m not a die hard, but binge it during various work projects like paintings). And I can’t even count the number of times he’s crystal clear about who and what he is. Specifically “I’m not a historian.”

So this reviewer is essentially criticizing the guy for doing his shtick, when Carlin is always honest and upfront about that. Makes the review seem petty and/or vindictive. Idk.
Considering this is a tech-focused website, my guess is it's less that it confirms our pre-existing biases, and more so that the community feels strongly about tech and its impact.

Similarly, if there were a website on gun control, I'm sure they would be more focused on how school shooting drills impact mental health than how Instagram impacts mental health.
