I learnt about Zipline in a talk at JuliaCon by Tucker McClure who spoke about how they use Julia for designing and tuning their aircraft. Had the great fortune of spending an evening at the conference to learn more about the company itself, how it got started and their use of Julia.

Recommend the 2019 JuliaCon video on how Zipline uses Julia for vehicle simulation:

And this video by Real Engineering that does a great job of explaining how the whole thing works:

Well, 2x 4k-8k 90fps streams (maybe both ways) for a VR/AR Headset comes to mind. Why in a park? I dunno, why not
My money would be on greater memory bandwidth and probably better use of that bandwidth.

If you look at the big graph later on in the article, even for similar _physical_ core counts the Graviton does better than the Skylake - this implies there's another bottleneck.

It's worth pointing out as well that ARM's weaker memory model gives it many more opportunities for aggressive optimisations that can make better use of the available bandwidth.
The dual vs single socket section really shows how much of a performance landmine NUMA is. You really need to properly pin your workloads, but that's a huge pain in the ass that often never happens during tuning.

It depends how bad it is. I inherited a codebase that had wildly inconsistent data in it's (schemaless) database, because there was no (or very little) input validation. When I joined, the dev team was spending 50% of their time fighting fires and dealing with bugs reported by customers. This was all justified by "move fast and break things", but the reality was that the code quality issues were massively slowing down feature development.
What is the performance per watt for Graviton vs Intel?
I strongly encourage developments like that. It’s a shame that Linux and macOS didn’t adopt something like Microsoft’s symbol server. This project could become something like this.

If you have an installation like this you can also plug it into Sentry as symbol server and it picks it up.
I completely disagree. I've been programming since 1977, when I was 7 years old. My kids, now in their teens, have been coding since they were able to bang on one of my 8-bit machines, having a blast all the way to comprehension and understanding.

Oh, wait, yeah. Sorry. I have every computer I've ever hacked on, going back to '77.

Yeah, now I get it. DEFINITELY don't try to teach your kids to program computers with, say, a modern web stack or whatever..

It didn't. Chipmaking is a harder thing to do than to run cat video websites, or a web hosting business.

> Also others where women claim, "men no longer chase" (my personal opinion is that it's because of metoo men are afraid of pursing and asking out unless if some woman displays explicit interest)

I really don't think it has anything to do with #metoo. I'm a very outgoing millennial male, and I think this all boils down to a decrease in sociability, largely centered around mobile phones. When I go out, I never think about pulling my phone out, but I see countless people in social settings on their phones...not socializing. Men used to have to get over the fear of rejection but now there are countless apps that put that fear to rest and let people pursue behind the comfort and safety of a screen, even if it means lower success rate.

Let me help you understand the reason, and why it’s not stupid.

NVIDIA’s RTX hardware provides only ray tracing capability. User software is required to add any path tracing, and path tracing is always built using ray tracing, whether you use RTX or not. The choice to use “ray tracing” when referring to RTX is deliberate and accurate. Calling it “path tracing” would be wrong and misleading. But it’s perfectly fine, and encouraged, to use RTX to make path tracing renderers and games.

“Ray tracing” has overloaded meanings. It means any time you literally trace a ray to test the visibility between two points (which path tracing does) and it also, depending on context, refers to Turner Whitted’s recursive shading model, and/or a ray tracing renderer that forks a ray path at reflection & refraction events.

“Path Tracing” also has overloaded meaning, and it tends to most commonly refer to the more vague meaning of any time you do global illumination using ray tracing. The more precise meaning of the term is referring to using a single high dimensional number, one that represents a connected path of rays, as a single sample in the space of the rendering equation. It’s a way of thinking about integration of the rendering equation that is analogous to what an individual photon does.

The strict form of path tracing is a single path that connects the camera or your eye to a light source. Almost nobody actually does that, because it’s more efficient to do direct lighting, or “next event estimation” at each bounce along a path.

So, “path tracing” is almost always used now in the more hand-wavy meaning that indicates there’s some global illumination. “Ray tracing” can also mean tracing rays on the way to global illumination. There is no distinct or hard line between these terms, but a good rule of thumb is if you’re doing global illumination, use “path tracing”, and if you’re testing visibility between points with a ray for any other reason, or referring to the mechanics of tracing one segment of a longer path, then use “ray tracing”.

Happy to see these videos posted, they are exceptional. He clearly understood this stuff at a very deep level. I recall reading a story somewhere about his collaboration with Danny Hillis at Thinking Machines (I think?) and applying his unique problem solving skills to the issue of coordinating so many individual processors to perform a job. He wasn't a "computer scientist" but he apparently applied some unique ideas that helped significantly.

No, same pay (but I'm only one guy in one company). And they're really no more stress than any other trip, they just require that you pay a little more attention to your legally available hours, and you communicate any problems immediately, so that CSRs can do what they do.

One thing that could happen is that the trailer could be taken from you, and assigned to a different driver who isn't having a problem with legally available hours. https://en.wikipedia.org/wiki/Hours_of_service
And your neighbour thinks the same. And by the way they have a gun. In a civil society disagreements are solved peacefully through voting and clear structures of accountability so you don't need to guess if you are responsible or not.

Even the same person disagrees with themselves over time. People who vote this way this election, vote the other way the next one.

You devise me a system where people are above the law according to their own judgement at the particular moment they see fit, and still not have violence.

This is why you can fight your entire life for the reform you like to see happen, and still not get it. But 50 years of exchanging ballots is always better than 5 minutes of exchanging bullets.

>I'm sometimes confused how far apart the general opinion on platforms such as hn is compared to people you encounter in real life.

Really? If anything I'd think HN of all places should be used to this class of problem, because it's endemic in much of tech particularly IT/devops, and we have arguably one of the more recent biggest and most well known cases of it ever: the Y2K effort. That was a massive industry wide problem that, in a rare case, also got significant media attention. And it was solved thanks to an utterly enormous level of effort. Hundreds of thousands if not millions or more of man years were put into going through decades of by definition crufty-as-hell code that maybe nobody had looked at in ages or had any recent mental model of and hunting for and fixing date issues. Sometimes permanently, sometimes through delay hacks ("let's consider 00-20 to be the 2000s, 30-99 to be the 90s" for example). Then there had to be lots of testing and dry runs leading up to the switch. And it mostly worked! There really were major problems, but they mostly came up in testing. The deadline was hit, it was a huge success. And the public result? It became the butt of jokes and a "cautionary story in overhyping a nothing burger" etc for the next decade at least. The general takeaway for the public seemed to be not "we solved this potential catastrophe thanks for a huge effort" but "we spent a ton of money and time and worry over something that didn't do anything!"

The basic issue of problems where the success scenario is essentially "nothing happens" but the failure scenario is huge costs is definitely hard to square with human psychology. Prediction vs reaction requires expertise in the subject that of course not everyone can possibly have, which in turn means non-experts must be able to identify and trust actual experts and institutions, with all the fuzziness and further issues that can bring. Arguably the ideal for Security, IT, ops, health, and many other areas is that they're mostly like air: noticeable primarily in their absence or degradation. If it's a particularly nice day and environment and the air is extra fresh we might take note of that as we first encounter it, and perhaps reflect at times how we feel more energized and clear headed then normal, but it's human nature to quickly let that fade into the background, and a significant amount of pollution or quality degradation is also something that can become omnipresent and looked over if it's not to the level of actual pain/breathing issues.

I don't know if there is any real formula for that beyond the hard work of institution building, with trust hard to gain and taking long time periods but fairly easily squandered. Even that may not be enough in the face of short term expediency and profit. Experiences like being treated as a cost-center and screaming into the void about security threats that we can see coming down the track from ages away and know have the risk of major costs are probably all too common here :(.
Interesting point. It's similar to how we consider inflation with regards to technological advancements. A cell phone still costs the same it did 10 years ago, but it's 5 times are fast now, so it actually got cheaper for that purpose.

The car you can buy today is many times better than any car you could've bought 50 years ago. Relatively, both you and your parents could buy a car, and they may have more money to spare than you would today. But they were definitely unable to buy a car that's anywhere near as good as what you can buy today.
Sure, but my high salary doesn't enable any of the things I mentioned. I'm still capable of making observations about the world around me; my friends, family, who have low salaries have access to these things and are seemingly able to achieve happiness through them.

Thanks! Here is one interesting example of a bug that was reported on the SQLite mailing list: https://www.mail-archive.com/sqlite-users@mailinglists.sqlit.... The SQL query that triggers the bug is rather complex. Interestingly, it was generated automatically: "I might not spell it like that myself, but a code generator would do it (and much worse!). This example was simplified from a query generated by a Django ORM queryset using `.exclude(nullable_joined_table__column=1)`, for instance."

When the user reported the bug, it had actually already been fixed on the latest SQLite3 trunk based on one of our bug reports. The query in our test case used a “NOT NULL NOT NULL” predicate, which is unnecessary complex as well: https://www.sqlite.org/src/tktview?name=c31034044b. We believe that this is interesting evidence that even “obscure” bugs matter in practice, for example, when the queries are automatically generated, as demonstrated above.
The primary material on Lesswrong is a mixed bag, but certainly some of it is very interesting even to people with training in Philosophy.

Although it is nice also to show off my Emacs setup during a screen share to a couple dozen people who don't know what it is. They treat the org-mode headlines, rearranging, todo items, schedules, etc, as some sort of magic. Org-babel with the results in a simple table kinda blew their minds. The number of project managers who want "my emacs setup" created for themselves was kinda funny, since they're all normally so focused on Microsoft Project or Jira.

WiFi is rather terrible, and I believe 5G aims to compete with it along with other standards.

I have a 90 sqm two storey house with a detached garage, workshop and quite a bit of land around it and I need 6 WiFi routers to get a signal everywhere, and even then it's spotty and slow.

Sometimes makes me wish I just had a data SIM on all devices and be done with it.

Open source 4g/5G stuff that was posted a while ago looks really nice, but apparently it would be illegal to operate :/

The environment is invoked like a playing card to create battles of financial starvation and just as easily overlooked when it would interfere with players' plans.

I do not understand why central banks are allowed to print money at low/close to zero interest rate. This will build up some kind of future subprime bubble where all the created cheap debt cannot be paid back. Central banks step in and save the financial system, more finance regulation is put in place but nothing is really solved. As an engineer working within operations, I cannot understand this as the root cause too much debt which cannot be paid back is not solved. Neither is the current economic system compatible with the environment. Common things we share like clean air and water and environment resources are not priced. You can profit from not being nice to the environment yet you do not pay for that profit.
fear also makes people drink bleach. it's not some unmitigated good.

fear can bring awareness of danger, but then (assuming it's not a literal imminent threat, like a tiger) we need to switch to rational thinking to weigh risks and consider options. we can't stay consumed in fear and expect good things to happen.

Partly, but they also actively go out of their way to disable security mitigations for reasons that are unclear so I’m not all that surprised. On Linux I think they were one simple buffer overflow away from arbitrary code execution, which is all but asking for an attack if you parse data from the network in an unsafe language.

Yes, but it seems like the grandparent was trying to fit in every polysyllabic word they could find.

They're saying that some groups tend to have more children and some have fewer. The groups that have more will become a larger and larger percentage of the populace (because they have more kids), and the groups that have few children will disappear. Therefore the global birth rate will go back up to the levels of a couple hundred years ago.

Gas powered model engines are not that unreliable, even for model airplanes. One made it all the way across the atlantic: https://amablog.modelaircraft.org/amamuseum/2017/03/29/trans...

Ok, the first 4 were lost but this is a huge journey with limited fuel and bad weather. And navigation was a problem too.

The big benefit of gas powered in larger vehicles is both the easy fast refueling and the higher energy density of fuel. Combustion engines for model airplanes are heavier than their electric counterparts because you can only scale things down so much, you still need to contain a constant fire and the associated pressure.

And in this usecase the slow recharge isn't really an issue anyway. It also makes sense for marketing reasons, being 'green'. Even though if fuel were used, you could probably run this entire company for a year on the fuel a semi truck would burn to drive 100km :) I don't think it would be a bad thing for the environment if a company like this would use fossil fuel, it's still a lot less wasteful than the alternatives.

I did specify "other factors being equal." A brain disease is clearly a special case, since the real advantages bestowed by first-hand experience (eg: better empathy, fuller understanding of symptoms) are negated by the doctor also becoming a mental vegetable. Further, unless you equate being "black" with having brain damage, how would that example even apply to the original issue?

The remainder of your comment rails against a position I do not hold, and did not claim to hold. My best guess is that you were thinking of Affirmative Action? Affirmative Action, as I answered someone else in this thread, is its own issue.

It doesn’t matter what I think, this is a widely reported possibility with recent articles from both the Times and the Guardian. Serious reporters at least believe there’s evidence of interference and possible data manipulation by China.

Basically the only thing we can conclude is that the numbers from China are suspect & not comparable with those reported by western nations until more investigation is done. Maybe it will turn out China was right all along, we just don’t have reason to think that right now.
