> I don’t believe JITs can ever beat AOT compilation.

In certain cases [1] JIT can beat AOT by a decent margin because it has access to live information that isn't available at compile time. In theory you could AOT compile, profile, and recompile but in practice my understanding is that nothing beats doing it live.

Consider that if the workload suddenly changes in production and your heuristic violates an invariant as a result, you can deoptimize, reprofile, and recompile everything on the fly.

But wait, you say! Can't an AOT compiler do that? But no, the state space is almost certainly going to be too large by many orders of magnitude. So unless your AOT compiler effectively inserts a JIT compiler ...

[1] Sorry, no examples to hand. Nobody knows but I'm actually a dog. Don't trust me!
GoThroughList – Setup Your CheckLists
I'm trying to do a historiographical quality history of computers, the kind of scholarship you might see with say the French Revolution or the Roman Empire.

What more, my history efforts ENDS around 1937; it's the BC part of computing that set the stage. The build up to computing.

Episode 0 lays it all out (http://comphistpod.com/introducing-the-computer-history-podc...)

I'm doing it in podcast form because it's 2020. This is going to be multiple years and I'm totally fine with that.

I divide the history up into multiple facets each with separate timelines.

Currently I'm going all the way through "electric communications" from the electric spark up through relay networks talking about switching, encoding, error correcting, signalling, all the important developments along the way.

In 2021 I'll close that out and do the same for storage (music boxes, looms, etc) and computation, starting with clocks, pascal's mechanical calculator and going forward from there, mechanical registers, overflow, adders, etc...

Each one is going to take at least a year or so.

I'm already about 2 months in to recording, about 6 months into the project. This week will be du fay, boze, desaguliers, watson, and the electric wire. Next week will be leyden jars, this is a long, slow project, and AFAIK it has never been done before.

I'm doing the odd episodes as a timeline and the even episodes as diversions and discussions to keep things entertaining and light.

This is the first time I'm talking about it publicly. It's at http://comphistpod.com

You're being harsh but yeah I kinda agree with you.
Just because India has 1 billion people does not mean that they would be better off buying inferior goods at higher prices.

Hong Kong is equal or larger than Austria, Switzerland, Denmark, Finland, and Ireland.

Taiwan is larger than all those, plus the Netherlands, Portugal, Belgium, and many others.

They are richer because of their adoption of free trade.

Local solutions to stop humans from destroying their environment.

We've implemented recycling maximally and created programs for reuse, repair, toxic waste, general waste reduction, battery disposal, returnables, etc. But it isn't really making a significant impact.

People still spend most of their disposable income buying things they don't need that can't be easily repaired, or that they can't bother repairing, or that they discard due to fashion, or because they are mostly packaging, etc.

We can't get them to stop buying useless stuff that they don't need. We can't stop them from buying new cars every few years.

We can't get them to spend money on quality infrastructure, like insulation, that would reduce their energy needs by about 80%.

We can't get them to stop going to restaurants or getting food delivery or take-out, which expends a multiple of the energy and greenhouse gases of cooking your own locally-sourced food.

We can't get them to understand that we're all going to die in fairly short order unless we bring the environmental disaster under control.
What part of their reply indicated they did not?
Fair enough. I think the problem statement does not have enough information by itself (especially concerning how rank is used to break ties for two pairs), and so it invites people to fill in the blanks using their knowledge of the game.
Instagram doesn’t have a share/repost feature, but people still do it a lot, either manually or through 3rd part integrations.

This leads to other problems like blocking someone, but still seeing their content because it gets reposted a lot.

Which is funny because we could say the same about competitions like Putnam, but that doesn't make Putnam any easier. But that's the problems with solutions, they are elegant and obvious, but only after the fact. Competition problems are explicitly created to be like that. These problems similarly, but because they could show a simple solution you can "justify" the racial exclusion.
I'm all for blaming dodgy chipsets, but the Superspeed and Superspeed+ support in Linux definitely has not had all of its rough edges filed off yet either--especially the stuff that uses streams and asynchrony.

However, the article comparing to USB 1.1 is silly.

If you are on USB 2.0 (and I haven't bumped into anything mass storage in the last 10 years that isn't), the bulk endpoints are quite happy to take advantage of the USB 2.0 bulk packet size (512 bytes) and microframes (120us turnarounds) with 13 packets per microframe.

That's going to get you in the 400Mbps+(40Megabytes/sec) range without a lot of problem.
I like the fact that you have to certify it is a picture of you. Reminds me the "Are you over 18?" on pr0n websites.

You know the answer. Mutual trade makes sense when trade deficit is managed, there is cooperation and symmetry. We don't need to go to aliens for that, right now we have China that's creating asymmetry in the trade and it doesn't play by the fair rules. For example, US allowing TikTok and WeChat but China banning Facebook/IG and Google.
I haven't benchmarked them - the h2plus is celeron quad core at 2.3Ghz, with on-board Intel graphics.

I find them fine for light interactive use, and running network services for the home network. Also gradually moving my lab machines over to them.

None of this is particularly CPU intensive, but does benefit from being x86 compatible. Also having M2 NVME + 2xSata on-board is nice :-)

I'm happy to discuss these issues more over email if you'd like to swap ideas.
> we judge ourselves by our intentions

People also judge others by past behaviors.

Wrong or right, many Americans see China as an enemy. News is filtered through that light. And some news, like convictions about IP theft by Chinese (Xu at IBM, 3 individuals at Sinovel, etc, etc, etc), leave little room for debate. These stories color the ones which may or may not be nefarious like TikTok. Guilt by association.
Yeah, one moment the kids are playing Dominion and the next they’re summoning Beetlejuice instead of attending Mass.
try http://www.uptimedoctor.com, I'm using that for my heroku project.
This immediately made me think of the C2 Wiki. It has a style similar to Taaalk in the sense that entries are often a mix of conversation and "exposition". It allows for that sort of linking by being a ("the") wiki. Perhaps that's a good model? A wiki where authors are visually marked as on Taaalk but otherwise all the accouterments of a wiki.

The not-quite-vaporware C2 followup implements some aspect of what you're describing via a sort of columnar layout.
Well, for one thing, "integration".

Domino's is built to deliver pizzas. They have streamlined the process of an order being placed, prepped, and handed off to delivery to try to make each step of the process as efficient as possible.

Do "horizontal" delivery companies have similar integration and benefit from similar efficiency?

In an ideal delivery situation, you want two things to be true: first, delivery people should be constantly moving. Second, orders should be handed off to a delivery person as soon as they are finished.

Is this achievable when delivery people are routed to new pick-up locations for each delivery? You want your delivery person to arrive at the restaurant right as the meal is finished -- if they arrive early, your delivery person is idle and your costs go up; if they arrive late, the food is cold and your customers are dissatisfied.

Restaurants with successful delivery components can solve this by tweaking their number of delivery people and their service areas in response to their busy-ness, so that they always have delivery people returning to pick up more food with an appropriate frequency. Have horizontal delivery companies solved these problems, either through integration with the restaurants or through some sort of big data magic?

So, here's the background:

After the ACA was originally passed 2010, it was challenged on constitutional grounds. It went to SCOTUS in 2012 (National Federation of Independent Business v. Sebelius, 2012). In that case the court ruled in a 5-4 opinion that the Individual Mandate was a constitutional and valid use of Congress' taxation powers. The law survived the constitutional challenge.

In 2017 a subsequent (now GOP controlled congress) zeroed out the individual mandate penalty.

The individual mandate is now being challenged on constitutional grounds. The logic goes that, since there is no penalty there is no taxation. If there is no taxation, the individual mandate cannot be a constitutional under Congress' taxation powers. I'm fine with all of that.

Here's now the part that I find absurd:

The argument that the individual mandate cannot be severed from the rest of the ACA based on the way it was amended by the 2017 Congress. Therefore, since the IM is no longer constitutional the entire ACA must fall.

The reason I find it absurd is it relies on speech and debate from the original passage of the ACA which argued that the individual mandate was required for the law to function. However, a subsequent congress deliberately chose to zero out the individual mandate without eliminating the law. The subsequent congress' decision making overrides the decision that the congress that passed the ACA. The 2017 Congress very deliberately made the individual mandate completely nonfunctional, while leaving the rest of the law in place.

TL;DR

- 2010 Congress passes the ACA with the Individual Mandate

- 2012 SCOTUS rules it constitutional

- 2017 Congress zeroes out the Individual Mandate

- The argument now is that the 2010 Congress thought the ACA required the IM to function, ignoring that the 2017 Congress very obviously decided that the ACA didn't require the IM to function.

To me there's just no way to square that circle. The 2017 Congress' decision overrides the 2010 Congress' decision.

-----

Finally, logically I agree with you and I agree with the 2010 Congress. The Individual Mandate is necessary for the ACA to function the way it was originally designed. The ACA is a better, more functional, law with the individual mandate in place. I disagreed with the 2017 Congress' decision to remove the mandate.

But that's no longer relevant. The question now is, is the IM necessary for the ACA to function the way the 2017 Congress amended it to function. The answer—since they repealed the individual mandate—is clearly "no".
I am not very familiar with Free Pascal. Does it have coroutines ? Modula2 does but there aren't that many free and maintained implementations around. There is of course GNU's Modula, but it wasn't very easy to install.

>a considerable amount of what we 'consume' does not entail necessarily excessive resource consumption

If you pay for some abstract service, the money goes to pay human beings who ultimately either consume or save, don't they? You pay for something that doesn't involve using a lot of resources in itself, but the money goes to someone who uses it to buy gas or food or whatever, so ultimately consumption is pretty proportional to dollars anyway.
Let me invite you to think through that position. Is this necessarily the case in all situations?

Are there situations where one could conceivably have a different outcome than abuse? Would it be a function of your popularity and the kind of of people who would DM? Might there be a different psychology at work for DMs than public tweets?

I’m not being snarky or presupposing answers, but just wanted to advance the conversation.
Kelley Johnson’s Skunk Works was successful because it rejected government controls and oversight. Read Kelley’s 14 rules of Management.

Johnson had a 15th rule that he passed on by word of mouth. According to the book "Skunk Works" the 15th rule is: "Starve before doing business with the damned Navy.“ because the Navy wouldn’t relinquish control of projects to the Skunkworks.

And it’s “funding” was paid contracts for performance, not an infinite credit line of free cash that Huawei got. Entirely different things. Huawei has sucked up a huge amount of Chinese resources, and there is no guarantee they’ve made a positive return, or ever will.

And SpaceX is a great example, just like the Skunkworks it’s NASA funding was pay for performance. SpaceX would have been out if business without the first contract, and would not be remotely as big today without the others, but those contracts have also saved NASA billions of dollars.

The vast majority of government funded projects are similar to the SLS, which has eaten up $15B+ in taxpayer funds without a launch. And when it finally launches 4+ years late it will be the most expensive launch system ever by a factor of over 2x per launch, and at least 20 times more expensive per pound than commercial launch systems. While reusing 40 year old engines!

This was a problem that I briefly worked on it undergrad. Turns out authorship attribution is an active sub field in comp ling. So you’re not just trying to obscure identity from human readers, but the neural nets looking through all your public writing as well.

For the interested some paper keywords would be adversarial stylometry and authorship attribution.
This is awesome. It like a super deep niche version of James Burke's Connections.
It's a great course but am I the only one a bit annoyed for the amount of questions during the lectures? I noticed by looking at the schedule many of the lectures don't cover all the material they are supposed to. He runs out of time.
There isn't much of a network effect at all once you hit a certain, relatively small, size which is why national ride-hailing businesses keep pushing the big ones out of their respective markets, and why there already are quite a lot of them competing profits away.

There's an illusion of network effects due to the investors willingness to burn their own money. Otherwise, like the actual transportation industry it's just a low margin business with tons of competition.

Meaningful network effects don't just make your company marginally better as you get bigger, that's true for virtually any business. It has to be shown that the size actually makes you run away with it instead of just leveling off.

The same is true in the fintech industry with all these much hyped neo-banks running on debt. Internationally they all tend to lose to local competitors because knowing your market and getting the details right is more important than scale.
Too big to fail is a complete myth. It's more likely the other way round.

> There should be no place for dogma like that in science

To do science (or even do any conclusion) one needs verifiable facts. It's facts that I miss here. That you claim that somehow you “know” something that doesn’t match any other observation, without providing any numbers or data at all, except hearsay, doesn’t bring anything to anybody. My only conclusion is that your words, unsupported by anything at all, after seeing different behavior across the world for months just can't be trusted. What’s the difference between your claims and any claim appearing on 4chan?

If you would publish your data where it can be verified that it shows something that is completely opposite of what's observed in the rest of the world... that would be something that I would surely praise. And the rest of the world probably too. Imagine that... something that gives a new information different to the experience of the rest of the world, and it is actually true. I just don't see that in your messages.

The dynamics of epidemics are known: Rt > 1 produces exponential growth. But the speed of growth is dependent on the value, and every exponential function has the initial part that "still doesn't look bad." Rt = 1 produces linear growth. Rt < 1 results in the decay of the number of cases. You somehow claim that you see something different than that, even if the simplest explanation is that your hearsay story was based either on Rt > 1 but on the small number of starting cases or on Rt practically being around 1 where the number of new cases is never hard for the health system, or it can be that during the period described Rt oscillated around 1, again not stressing the health system. And all that is dependent on behavior of millions of people, who can in their environments, which could be relatively isolated from the rest, have their own initial conditions and their own Rt values.

But we just don't know what happened there -- we have no useful data from you.
And like many ratings sites BGG ends up weighted to novelty. Is this really the best movie / novel / video game / comic book / burger ? No, probably not, but it's the popular new one right now among people who watched a lot of movies, read a lot of novels, played a lot of video games, read a lot of comic books or ate a lot of burgers as appropriate.

Unlike built-in ratings (e.g. Uber, eBay) these ratings do at least provide some value at the low end. There are a fair few games on BGG with 5.0 or lower ratings and you probably just don't want those games, sight unseen.
How can we document "human society" in 1000 pages or less? I've been casually researching for a while, and will eventually write a guide on going from zero to the moon.

Step one is survival, basics of hunting, first aid and farming sort of stuff. That volume would end around homesteading and self-sufficient living.

Volume two would be establishing society in larger groups than a family unit. Things like job specialization (N roles for N people instead of 1/N of each role for each person), establishing trade (currency, weights & measures, supply chain), government (mostly what not to do, what to protect, how to adjudicate disagreement), public works ("roads are a good idea") and their ilk. Also medicine beyond first aid and basic care.

Volume three would be advanced STEM topics, getting from a functioning society to... more. Not even the sky's the limit. It should include blueprints for things we take for granted like refrigeration, telecommunication and birth control. It will include all the basics of physics, chemistry and biology required for smart people to fill in the gaps and launch a human to the moon and back.

I want to super-nerd-out about this, and publish it on Tyvek or something exotic so it'll last through decades of wear and tear (and water-logging and more), and include a ruler on the spine and it's own weight documented for reference.
