There have been times I wondered if such a group was formed, or only working from a spot in international waters or, what would be some country names that would avoid any kind of legal or treaty or anything. What would those places be that could have such a hive running without major recourse?
That is indeed wrong, wonder if there's some public feedback mechanism for reporting non protocol conforming intersections :)
I'm curious, what sort of approaches do you take to your programming tasks at work? Is it more like e.g. writing SQL where you'd think more about relating sets of data rather than looping over individual items?
Both ultra-low-level and ultra-high-level languages are easy to grasp. Ultra-low-level concepts translate better into logical skills, how to think, etc.

I think it would be genius. Imagine if you could get absolutely free transportation anywhere. Uber/Lyft is great but prohibitively expensive for a lot of people.
Since this isn't being flagged for some reason I am not going to let you get away with posting a garbage useless reply for free.

Depression is on the rise. Suicide is on the rise. We have all these "freedoms", society has made all this "progress" and our youth is sadder than ever. Explain? More divorces, more disconnected families, more violence. Offer your theory than the easy trope.

You might have your theories, I have mine. Doesn't make it horse shit and I stand by it, so unless you have something constructive to say, you can shove it up your ass.
I've seen packaged meals in a couple stores but none of the biggish chains I shop out. Not sure why it's not more common. It's not like there's any shortage of prepped vegetables and the like. Actually seems an opportunity to sell meal kits with more stuff pre-prepped than Blue Apron does.

People get down on Knuth for the same reason (the author of, by far, the hardest books I’ve ever read), but in Knuth’s case it’s actually just that he’s being absolutely concise.
I think you're ignoring how revolutionary free transportation would be. Even it was annoying, you'd change so much and if you didn't like it, you could pay money to have no ads or a car to yourself.

I wonder: if one is generally healthy and the air quality is unproblematic, should one get an air filter? Does air filtration potentially lower long term immunity and make us less tolerant to particulates?

I worry about the long term effects of being “too clean”, that is, I think there’s something to hygiene theory of disease. The body needs small stressors and perturbations in order to thrive.
I’ve been using Firefox since I heard about their containers. I’m happy they are pushing for all these privacy tools. For me these are the features that will make me chose over chrome.
This is a good example of why Firefox is so important. Mozilla's incentives, unlike those of companies making significant revenue from tracking-based advertising, align with the user. Google, for example, could have implemented Chrome's sync feature in a privacy preserving manner, but instead chose to use it as a method to collect their users' complete browsing histories.
I know driverless cars are supposed to be the next big thing, but I have to say I've become a bit skeptical that it will improve quality of life at all. We can use technology for guided driving that is as safe as, or even safer than, full automation. And what are the other benefits? More time in the car to do what, scroll Facebook, work remotely, and look at ads?

No thanks, rather focus on driving.

AMD's optimization guide for Zen (https://developer.amd.com/wordpress/media/2013/12/55723_SOG_...) suggests:

> The LS unit can track up to 22 outstanding in-flight cache misses.

So not as much as Apple, but more than Intel in this regards. I probably could test this, but I'm tired today, lol.

----------

10 outstanding loads per core seems like a small number, especially compared to contemporary processors (Apple or AMD's). Maybe Intel knows something we don't.
Have you reviewed the lectures and other course material or just jumped into the problem sets?

A thing that may help: Approach this CS50 material as if you have no knowledge of programming. Set aside your preconceptions about both your ability and the nature of programming itself (to the extent that this is possible). Review the materials and read/watch all of it, even the things that you know. You may know them, but exercise the discipline to persist through them and practice the material.

This random reddit comment describes the situation with NYC subsidies pretty well. It jives pretty well with what I saw locally when they built the Whole Foods near me in Gowanus.

https://www.reddit.com/r/nyc/comments/9wploz/ocasiocortez_bl...

Overall, a much better argument against these subsidies is that they shouldn't be needed at all. Everyone should be able to have the same streamlined permitting processes.
How does Firefox Sync handle a user changing their password? What if the password is changed from another device? Does it force users to first sign in with old password and only then allow to change it, essentially re-encrypting everything and syncing again? If so, does that mean forgetting the password equals to losing all synced data?

Putting aside the damage that issues with correctness can cause, the problem is exactly that if you e.g. wrote something that grows with n^2 instead of n log n, you cannot scale by "brute force" anymore, as the inefficiency very quickly outgrows the amount of resources you can add. Seriously, your thinking that "algorithmic inefficiency" can be countered by "scaling" is almost proving the point.

CS is by far not just about runtime complexity, but it's one thing that can bite you.

Also, all the components you mentioned were likely written, at least in significant parts, by people knowledgeable about computer science.
I think one of the problems is that color and what you see is somewhat tightly related where taste and how taste works is highly varied.

While you can get some sort of single-molecule chemical representation of some specific smell or taste, that would be static (as in, the formula or construction wouldn't change) but most people would smell different things.

I suppose for those 'inventions' the recipe or method would be trademarked/copyrighted/patented but not the result.

I've been hearing about the Lightning Network for many years, but is it a real thing that can actually be used to solve a problem (high transaction fees/long confirmation times/?) yet?
> That's bad for code that can handle overflow and do something reasonable, like switch to bignum integers.

I see that as an argument for throwing exceptions or setting a flag on overflow, not for silently wrapping to negative values.

Defining signed overflow means that I can't enable runtime checking of it without erroneously flagging intended cases of overflow. To deny that to support the tiny percentage of developers who write bignum libraries strikes me as a poor tradeoff.

(Simply checking for a sign change isn't sufficient for implementing bignums anyway. It's trivially possible to multiply a large positive number by a small positive number and have it wrap not only past negatives back to positives, but to a number larger than the input.)
Tianeptine is an anti depressant prescribed in some countries outside of the US that has an extreme opiate effect when taken in extreme doses. I think the idea of finding opiate like drugs at effective doses to treat depression but skirt physical addiction is interesting, but a dangerous game indeed.

I remember Pournelle was a big fan of S-100 based systems because you could upgrade them. His motto was something like "silicon is cheaper than iron," meaning that you could replace boards in an S-100 system rather than buying a whole new computer.

This is a really great article. The level of detail is perfect. I feel that I could implement a similar encryption system as a proof of concept after reading it. It seems so obvious but it really does go against the grain of many of the more common approaches (as explained in the article) because respecting the privacy of a user is so unusual.

> heavy on straight CS theory. “how do you sort an unordered binary tree in place“ kind of thing.

I was having a related conversation earlier, and feel like I'm reprising the same argument for a new audience, but... I don't see what is either Computer Science or theoretical about that. It seems like an eminently practical task: Handling things in a tree structure, sorting items, and doing work in-place to conserve resources are all very concrete, real-world aspects of writing software. You might not need them in _every_ case, but they aren't really "theory" in any real sense.
If a self-driving car can serve for 5 years without a costly overhaul, the amortized cost is only $250k/5 = $50k per annum. Let's say the annual maintenance is $10k, the total would be $60k a year.

It can possibly serve two effective shifts (in fact longer than that but the demand at some hours could be lower and it may need some time to charge, unless battery swapping is performed), which means the cost per shift is only $30k per year which could be in the same ballpark or a bit lower than a human driver would make per shift (depending on the market it serves, etc.)

This is just the beginning though and the costs will most likely come down while the human driver's costs will likely go up.
Nonsense. I'm in tech, and I think it's a ridiculous waste of money to give Amazon billions of dollars in tax incentives to do something that they were likely going to do anyway.

It isn't a "NIMBY backlash" to acknowledge that this was a sweetheart deal for Amazon, and that it doesn't make a lot of economic sense. Moreover, at least in Queens, there's very little chance that it actually benefits the people who live in the neighborhood today.

You've got to be kidding me. But yes, if you literally have a fan and a filter then why do you need to spend more money.

Autism and Mental Health: taking it personally
Somebody once said, "Bad teachers prepare kids for bad bosses, which they are likely to encounter." While I agree with that to some extent based on actual experience, taken too far it can hamper education. If you flunk math or English because of a bad teacher, it can set your entire education behind schedule. Perhaps make sure the difficult teachers are not in key subjects that have course path dependencies. Similar for books. (You will encounter poorly-written instructions in the work-place, which difficult books prepare you for.)
I wasn't talking about deep learning at all. I think most google technical docs suffer of a little bit of "and now draw the rest of the Owl" style.
It's not technically challenging, but it's harder: Politics moves more slowly than technology, and Uber had to be so good for so long that politicians had little leeway to maneuver.

AMD processors have 44-stores in flight, but only 22-loads in flight.

I presume Intel processors have a similar difference between their "store buffers" and their "load buffers".
I pretty much try to look at every issue from what I could've done better viewpoint - doing the same here. So no offense:

- as a small company CEO, you get less leeway in terms of who you can hire. So there is a high chance his hands were tied and the on paper experience folk probably looked much better than a really really good newbie. Think about it from the perspective of a lay person or busy board member: it's pretty much like how you'd choose a cardiologist. You gotta play the numbers unless you have some great insider scoop. Playing safe is a sad reality :/

- if you really had the ceo ear as you say and carte blanche, you have a part in not making that a productive setup: a ton of people would love to be in that spot, probably would produce more too.

- at the end of the day, your only irreplaceable value in life is your time. By messing around with 'cool projects' that didn't mean much, the biggest loss here is yours.

- ratholing again on the privilege part, if you were that established, no lifer would've been able to affect you that much. There is probably a miscalibration here in your opinion of yourself.

Again - really no offense. Just what I would take away if it were me.

Now, you might be shocked to learn that color can be part of us design patents.
Then it is a theorem, as it is tautologically implied by certain axioms imposed on preference relations or choice correspondences, such as completeness, transitivity and a notion of continuity.

Since the whole theory won't fit in one wikipedia article, I suggest you read the first chapters or either
a) Mas-Collel, Whinston and Green
or
b) Kreps, Microeconomic Foundations I (not the old undergrad book from him)

This would provide you with the theory to understand this result in a more mathematical correct way.
I don't really understand that even booming areas like Northern VA and NYC have to give a company subsidies to settle there. I can see this as a tool to help disadvantaged areas but I don't think we should subsidize wealthy companies to settle in already wealthy areas.

As an ex-small business owner I would much prefer if little companies got more incentives.
Shorter range lidars (<10m) tend to work in the frequency domain because you can get pretty good ranging accuracy.

Longer range lidars work in the time domain. The SPAD detectors used by Ouster create a pulse when a single photon is detected and so you're measuring the time of flight of the photon being emitted by the vscel and then being detected by the SPAD array.

Chess is a game where everybody can play it almost anywhere, and there is no physical advantage one has over
another. There also is a huge amount of stuff that is possible to learn about the game to become better at it, so
there is no real limit to how much you can learn about the game. The only thing that I dislike about chess is the
people who play it. The culture around many chess circle's seems very pretentious and snotty to me.
It's been about three years since the original release of the whitepaper.

One thing that's frustrating in the Bitcoin ecosystem is that it turns out barely anyone actually wants to fund development of the lower levels of the protocol.

Because anything of value is kept tight for investors and for the possibility of more investors? Early startups don't have much else to offer, which is not to say the way startups is done is morally commendable.
I'm actually a YIMBY but I don't consider the Queens backlash against the Amazon's HQ2 NIMBYism. Instead its a valid argument against why Amazon should get billions in subsidies to essentially gentrify Queens -- what will the actual inhabitants there see, other than landlords mostly getting higher rents as they push existing tenants out? These kind of 'race to the bottom' economic subsidies that states and cities compete on should be eliminated IMHO.

I always heard of anti-vaxxers as bipartisan stupidity - although also largely middle or upper class because the poor and working class - partially because literally can't afford to pass up something that might make them sick and partially because they are often well aware that they aren't well educated.

Stereotypically vaccines are too 'unnatural and not flattering to their holisticism' for the left branch and the right are too scientific elite or government conspiracy for the right.
No this is exactly what nimby means, tons of people who would support HQ2 being in manhattan are opposed to HQ2 being in LIC.
The computers needed to run self-driving cars are not the expensive parts. The sensors are. And the sensors are expensive because there are so few users.

High-precision accelerometers used to be extremely expensive, with the best having prices in the high 5 figures. Then companies started putting (initially really crappy) accelerometers into smartphones, just to know which side is up. Then economies of scale hit and suddenly every smartphone has an accelerometer better than those super-expensive ones, and cost per part is pennies. (And then drones became a thing.)

The same will happen with LIDAR. Nothing about any of the parts of a self-driving car requires it to be super expensive, it's just that things that are made in quantity are cheaper than special snowflake parts.
Absolutely agreed. It’s not like NYC had to issue large tax breaks to woo any of the other large tech companies with a presence there; the talent pool and allure of the city to new talent is something NYC already has in abundance.
Yes, sort of (more about the process: https://github.com/mozilla/fxa-auth-server/wiki/onepw-protoc...). Key difference: you don't need to sync all the data up again, since there's a separate key for that, which doesn't change.

That said, if you forget your password you do lose remote synced data. The hope is that you have at least one device connected that still has the data, which will upload it in that case. This doesn't work in all cases (there's a pretty common and unfortunate pattern where someone reinstalls their OS, doesn't remember their password, and loses data as a result)

You can also generate and store a separate recovery key to help avoid data loss, https://support.mozilla.org/en-US/kb/reset-your-firefox-acco....
