Thanks! The idea of having a list of migrating entities per chunk is good, and it avoids locking on the list of all entities in a chunk. But I still have some confusion about it:

> The server looks up the destination in the "active chunk set" I mentioned

but what if the entity teleports to an inactive chunk?

> and then uses per-chunk std::vector<>s guarded by a mutex to push "migrating" entities.

Will these migrating entities participate in later calculation within the same tick, or are they excluded? If excluded, what happens when there are two mechanisms that mutates that entity, but the first one put it into the migrating list of another chunk? If included, the thread of which chunk will continue this calculation?

And when some kind of mechanism mutates two entities in different chunks, which thread is chosen to run this mutation? And how does it mutate the state for an entity in the other chunk?

Meanwhile since you mentioned ticks, (just to be sure) are you using a barrier per tick to wait for all threads to finish the same tick? When are the migrating entities merged into the main list, and are you using another barrier for that?

It wouldn't make any difference. The US can ultimately get at any technology in China just the same as China can get to any technology in the US. It wouldn't remain secret for very long no matter what they did. In fact long before they officially figured out fusion first, the US would realize what they were on to and react; just as China would the other direction.
Not sure why you're getting downvoted, everything you say is pretty much on the money.

Alas, Ristretto implements an eventual consistency.
No, I'm not. I'm pointing out that science is evolving and contentious and that as convenient as it is for people to declare victory and claim that science has settled and, in turn, settled the arguments they've found themselves in, science tends not to make any such claims. If you think that's not the case, and that, for instance, science has conclusively shown something that TGD safe-space people don't want to hear, I think it's likely that it's you that misunderstands what science is and how it works, not me.
A good friend of mine from high school is a Navy SEAL. He was shot in the leg in combat (similar to the guy from this story, though not quite as bad; but still multiple surgeries and over a year of recovery). He said he'd rather get shot again than go through BUD/S again.
> Why the fear of opt-in competition? Nobody is forcing anyone to move to these places. What they are is an opportunity to try out new governance modes.

It's a governance mode that was heavily used throughout the European colonial period and it resulted in the rape and theft of the local populations and underclasses of all the nations involved. When you put things in the proper historical context, the hostility is rather well-reasoned.
Except the groundwork has effectively gone out of business and no longer has anyone working there.

They made a good faith effort to find non HRC campaign and non profit customers after the election but never found meaningful market fit. It was an odd assortment of tech that felt like what it was: an attempt to productize an enormous consulting engagement to build whatever the campaign wanted.

It's all an interesting campaign finance loophole though. You can fund money loosing tech companies to work with candidates and as long as they charge the campaign something, it's an interesting way to spend huge amounts of dark money on elections.
Boeing stock price today is 337.55. In Jan 2009, it was $42. That's a 8x return.

SP500 closed at 3221 today. In Jan 2009, it was about $890 and that is only a 3.6x return.

Hindsight is 20/20, but you might've been even happier if you kept all your 401k in Boeing.
Play store listing post mortem
> Games have minimal dependencies re OS APIs wise.

Sure, if you exclude "let's use every little quirk and undocumented feature in the graphics and audio and input stacks we can find because gotta go fast sanic noises".

Both games and office software (ab)use OS APIs; the difference is the specific subset of those APIs said programs (ab)use.

So yeah, you're right that it ain't "bullshit", but don't write off games as somehow "easy" compared to office programs; a substantial amount of effort has been poured into reimplementing Windows' multimedia stack in Wine and continues to be poured even now.

You’re sidestepping the problem. The problem is that Python uses the same syntax for variable declaration and variable assignment, and this can lead to unexpected behavior. That’s far from normal in the programming world, making it more unexpected.
We'll be taking some of this approach at our new co, bootstrapped, with very generous share grants for the first employees. We're doing partially remote, but I think full remote might make it too hard to get the core team as tight knit as it needs to be. I don't think it's a good substitute for a few people sitting in a room yet, but I could certainly be wrong about that.
Don't be an employee at a startup unless they pay you really well. If you want to play the startup game, found your own company that does not rely on burning VC money.

Here is a list of physical activities to stimulate your memory or imagination. There is more to exercise than the gym.

Swimming, Soccer, Rock Climbing, Hiking, Kayaking, Free running, Martial Arts, Fencing, Yoga, Surfing, Dancing (Samba, Ballroom, Contemporary...), Long walks, Cycling.

My favourites are cycling because I feel so free and I love the sensation of speed and climbing because I have a natural talent for it and I love the feeling of getting to the top.

My experience with big data analysis immediately leads me to suspect that in a dataset of tens of millions of elements, 100 elements having anomalous behavior can actually be operator error, hardware error, noise, anomalous near-Earth object miscatalogued as a star, &c. The article touches on this possibility: "Another explanation – although very unlikely – is they're all just scratches after all, and never existed to begin with." It's unlikely, but unlikely phenomena become phenomena one expects to see if one "rolls the dice" 10 million times.

But it is still an interesting story and a topic worth exploring, even if subsequent research concludes the team has found 100 smudges on glass.

As long as there will be people born there will be demand for land for it being the necessary condition for life and industrial production.

Billionaires now looking for ways to acquire more land? Or to create artificial land on sea? Or to discover new continents or planets with new land? Nothing new under the sun. Guess where all the money acquired from current day monopoly industry ends up in era of zero interest rates and rock bottom innovation. Of course the majority of it is parked in land.

This is not capitalism. This is feudalism. Just rename 'billionaires' to 'aristocracy'.
I've used this, unfortunately I've not had a good experience with it. Say I was to have a keras model, and use a tensorflow backend, and then use the plaidml backend and compare the results: They're different in a radical way.

Also I don't think they've got their driver usage right. Metal on the GPU gets different results than OpenCL. OpenCL is supposed to be the 'beta' and the results are more stable with it - and again different radically between the PlaidML devices.
(Went to school in the Netherlands)

I think I mostly agree. Some of the parts of school sucked, but overal it was a fun experience, with a decent enough balance of bullies and friends.

I’m not quite sure I saw it like that at the time, but I never hated it.

I also find that everything I learned in high school is used at some point or another (maybe the french is an exception), Biology is great when raising kids, maths are great at any point in life, though the more esoteric ‘resolve this equation’ things have yet to happen, geography is nice because I know what causes the earthquakes, what makes the typhoons that pass by once in a while and so on.

It only becomes clear to me by comparison how great and well-rounded my education has been, sometimes I wonder if other people went to school at all, and if they did, what did they do there all day?

While I think university might have done a better job of preparing me for work, high school did a great job of preparing me for life (at least academically).

And really, work is just a more complex high school socially speaking.

The biggest hurdle to having better cognitive abilities is living within a culture of ignorance where critical thinking isn't thought of as a necessary and desired skill.

The poster I replied to here created a straw man argument based on my lack of response to another comment. I didn’t think that was fair considering my bandwidth limitations, so I decided it would be best to set expectations. My response to the “math changing” comment has now been added above.

Do not assume that the lack of response of somebody else implies anything aside from the fact that they didn’t respond. They could agree, disagree, or maybe they haven’t even read or thought about it yet — and maybe they never will because something else distracts them.

I think discussions tend to be the most productive if we assume everybody has the best intentions. :)

Look at what eventually happened to MySQL. And why mariadb now exists.
As tech becomes infused into everybody's daily experience, a certain amount of conservatism is not only to be expected, but probably wise. The "move fast and break things" startup approach isn't necessarily optimal in all facets of life, and a lot of the low-hanging fruit of "possible significant improvement if we succeed, low societal consequences if we screw up" is plucked.

>many cities have regulations against shooting off fireworks due to safety concerns. Few rural counties do, because while people can still harm themselves, there aren't too many others nearby to injure.

Many rural counties have them as well. In fact entire states have rules against fireworks.

Outside of places where wildfires are likely, firework ordinances are often there to prevent the people who are shooting the fireworks from hurting themselves.

>If someone goes to an island in the ocean, why ought we to care what he does there?

In an extreme case lets say a billionaire starts his own island nation, convinces people to move there to work for him, and eventually enslaves his workers and their children. This isn't an unlikely scenario--look at guest workers from SE Asia in the Middle East. What starts off as voluntary can quickly become involuntary.

We have enough powerful people in the world with no checks on their authority. We don't need to create more.

From a more practical concern, what's the upside to existing countries? The new island nation will only admit productive people, and will likely try to ship unproductive people back to their country of origin.
> A lack of physical exercise is going to put all cells, including brain cells, in a catabolic state the same as muscle atrophy will waste away muscles due to lack of physical activity.

Why is this? Using your brain cells won't lead to muscle atrophy.

From research we know physical activity is healthy for the brain, but there's no reason this should be the case from first principles. You can make the same argument in the other direction.

"The brain and body have existed in state with limited energy. So to maintain homeostasis when the muscles are used it puts the brain into a catabolic state to feed the new stronger muscles."

And if catabolism between muscles and the brain is linked then surely steroids will make people every smart by switching the entire body into anabolism from catabolism.

> Cells are cells, they are where energy is made, they are binary only existing in anabolic or catabolic states and never simultaneously existing in both states

This is 100% not true. All cells are simultaneously building stuff and tearing stuff down. Some hormones like insulin say "build more stuff, tear less down" and others like cortisol say "tear stuff down and stop building".

But the body can simultaneously build some stuff and tear other stuff down. Consider the transitions from different types of muscle fiber. From beefy body builder muscles to lean marathon running muscles. That will be tearing down a lot of proteins but building up a lot of mitochondria.
This is certainly more exception than norm.

But overall, strict rules on where it would be considered more of personal choices elsewhere were governed by such rule.

Back in where I was in middle school (close to 30 years ago, so certainly things have changed), I had:

1. Mandatory close clipped hair for male (repealed within first year I've attended -- I heard it took like 4 years of school council's effort do make this happen.)
2. Socks must be white
3. Shoes must be white

There were somewhat implicit rules against hair dying, and eating lunch box early (latter being more universal norm) -- both actually caused big scandal when someone actually did those...
This is a great reminder. I was impressed by the recent documentary "General Magic" by how much smart people seem to congregate around new ideas. The old Mac team was the same one trying to create the smartphone 10 years before it was possible, and it was that core of folks who ended up doing it at Apple and Android later anyway.
The problem is that people seem to think that one must drink the coolaid to do well.

I have worked for both small, large, internationals and startups.

A startup is a massive risk. 99.5% of them fail, of that 0.5%, >50% are acquired which is a spectacularly brutal experience. Odds are, your startup will fail, and take you with it. (especially as those of you in the US have to think about health insurance.)

Most of the time you'll be making fudge after fudge, using stuff cause its shiny and regretting every choice you made 6 months previous. then you have to deal with the batshit social rules are de rigueur.

Either way, you can either choose to believe that your company is looking after your interests, or treating you like cattle (Kobe beef, if you're lucky enough)

Far too many startups require their staff to blindly worship the co-founders, even though they are obviously deficient, only useful for tax write-down fodder. Look the other direction as your boss has a spectacular mental breakdown, or decides to initiate conjugal relations via blackmail and obnoxious power plays.

Basically, you can't just slap the word startup on a thing and allow it to fuck with peoples lives.
Also: many techs in the article have a much longer time-horizon than indicated.

TCP/IP / packet-switched networks date from the early 1960s. Apple's first smart-tablet, the Newton, famously flopped. I remember seeing one at work in the early 1990s and saying "why would anyone want anything like that?" Given its capabilities, or more accurately, limitations, that was accurate.

IoT two decades ago was powering the first generation of pop-up ads as X10 home-automation systems. Blockchain is rebranded Merkel trees, dating to 1979.

Drones, as with most other aircraft-based technology, is a matter of lightweighting systems sufficiently, at a reasonable cost, to enable them to remain aloft. Even now, the popular copter-drones have only a few minutes of operating time. Further lightweighting, fixed-wing, fuel-based, or other changes are likely still required.

Self-driving cars are a problem of complex nature in which further enhancements to basic automation provide ever-increasing domains of application.

AR/VR suffers from human-machine interfaces. Simulator sickness (https://en.wikipedia.org/wiki/Simulator_sickness) affects professional pilots -- a device that makes a substantial portion of the population physically (and projectilely) ill will have limited uptake.

4. Which people and institutions will be most impacted by a technological solution?

5. What changes in language occur as the result of technological change?

6. Which shifts in economic and political power might result when this technology is adopted?

7. What alternative (and unintended) uses might be made of this technology?

All fats can substitute for each other depending on recipe. It will taste different but it's really fun to replace fats with other fats.

Ex, bacon grease works in more recipes than you'd expect.

Just memorize their smoke points, the point where a fat begins to burn. Shortening has a very high smoke point, but that is only relevant if you expect the temperature to go above 400F, such as the mallard reaction (aka the taste of fried / saute food).

You'll learn pretty quick when a fat burns quickly. Olive oil and bacon grease burn at really low temperatures and will create a thick cloud of smoke as it burns.

Look up the smoke points of fats if you are worried.
