The most important section is on involute curves. It's the curve formed by unwinding a string against the circle:

https://ciechanow.ski/gears/#strings-attached

It creates a constant angular velocity ratio at all points where the gears mesh (the law of gears).

In layman's terms, the tip of the tooth gets thinner so that the angular velocity there is reduced at that larger radius. Otherwise the gears advance/retreat as they rotate, which creates vibration.

I think there might be a whole host of curves that work for this, the other main one being a cycloid, which I'm not really familiar with:

https://en.wikipedia.org/wiki/Cycloid_gear

I first learned about involute curves from a cousin that works as a machinist. Mr. Wizard also blew my young mind with noncircular wheels:

Edit: stumbled onto this technique to make involute gears in CAD:

If someone has a simpler method, I'd love to see it.

Why on earth would a farmer pay for an insanely complicated system like that?

Besides, what exactly would the farmer do when the drones detects a wolf? It's illegal to shoot or bother them in any way.

yes, i was commenting more on the impetus for the rise of insular, faux "microcommunities" in general than on the walkability therein, which, as you point out, is better at 3rd street & the grove.
another trick I learned about from another HN thread: if you hold the space key you can then move it like a cursor to navigate.

though recent ios update seems to have made it auto-highlight a word after moving. so for instance if i move the cursor up to start of sentence it will highlight the first word which is hard to deselect.

Even for Let's Encrypt it took 3 years before they were comfortable to abandon the IdenTrust cross signed certificate, and they won't even do it until July 2020, so a whole 5 years.

That's from a very popular NPO supported by many corporation.

Well, like I had responded to that comment back then, casting is very explicit in Haskell, but I think they were confusing casting with type inference. Most of the time, 0.1 + 0.2 is the same thing every time, but you do have the option of it being different types, depending on what you need.
I remember back in the early 2010's that a large selling point of SAS (besides the ridiculous point that R/python were freeware and therefore cannot be trusted on important projects ) was that it can chew through large data sets that perhaps couldn't be moved into RAM (but maybe it takes a week or whatever....).

This was a fairly salient point, and remember circa 2012/2013 struggling to fit large bioinfomatics data into an older iMac with base R.
That's fair. In ~200k miles of driving I've also had zero accidents so maybe it's a stretch to call these things 'tragedies avoided'. But the point stands that Autopilot does little things every day to improve safety, but they get little media coverage since they're mundane and boring.
Indeed. Giving Essential money is giving Andy Rubin money. I could never give Andy Rubin money with a clear conscience.
While I feel sorry for the people that put the energy to make this happen and also for the people that may lose their jobs this month over this, as a native inhabitant of Barcelona, I can only celebrate the news, even if it is for this terrible reason.

When MWC is ocurring in Barcelona, public transport (subway) goes on strike (because of the maximum impact). But usually this only fucks over non MWC attending people, because tickets are so expensive that only people which can use a taxi anyway will go, greatly diminishing the impact of the strike for attendants while making inhabitants lives miserable for that time period.

Also, Barcelona already has a very severe problem of houses being rented out to tourists with very high markups, producing a gentrification of the city (along with other factors, not only the tourism is responsible for this). Events like MWC do not help this situation.

BCN is already overloaded with tourism, events like MWC only make it worse for those of us that live there.

I'm completely aware that this is not the responsibility of MWC organization or tourists, this is a regulation problem. But since regulation is stacked against us, I can only get happier that this year we won't have to suffer all the inconvenience of the event while reaping almost none of the benefit.
Former fusion startup founder here.

It would have been interesting to note how many (and which, if possible) startups were specifically taking advantage of each item you mentioned. This would make a much stronger case that it is technology driving the expansion rather than money. Obviously, REBCO tape is being used by a few (Commonwealth comes to mind) since better magnets are usable everywhere in magnetic fusion. However, it would be useful if you could point to, for example, a startup that was using engineering decisions from ITER to derive their plasma-facing materials. Of course, if this information is not public-facing, I totally understand why the article is so vague about it.

Regarding the graph, well, it reminded me of an old HN comment I made a while back: https://news.ycombinator.com/item?id=16552007
Agreed, but I have some more reasons for why the "phone" part of the phone isn't really much of a factor when it comes to buying a phone these days.

At this point in time, texting+phone parts of the phone are pretty good and uniform across all devices, so it isn't a differentiating factor that people care about anymore imo. The only "texting" part of the modern phones that is still somewhat of a differentiator is iMessages, but that's about it.

My friends like to talk about how awesome it would be to time travel or know what the outcome of a future decision will be. Even when armed with knowledge from observed outcomes of near-identical setup scenarios, majority of the time they end up doing exactly what they would have normally done. Happens to me from time to time.
Less light in the retina, yes. But there are different types of "blind."
That's not what happened. The AI was not programmed to drive through anything. It was incorrectly programmed to dump previous data when the categorization changed. It correctly identified at each point that it was meant to slow down and/or stop but, by the time it determined what the obstacle was, the previous data was thrown out and it didn't have enough time to stop properly. In your example, it was more like "There's something that 12 o'clock. Bike? Person? Unknown? Stop!!" just before actually hitting the person.
At a brief glance it seems they ensure idempotency w.r.t. possible errors/network failures etc. not necessarily to multiple purchases done by the customer by mistake.

In that case I think some high velocity fraud filters should kick in (which they probably did). Indeed the purchase amount is very large, so you wouldn't really expect it to be a repeated high velocity buy. On the other hand Stripe can't really cover all possible edge cases all of the time.
I agree, there's so much about the brain we don't understand, plus whole sections overlap or process multiple sources. Nothing is simple in the brain! In terms of the amount of your grain required or dedicated to each input this says nothing.

However, the statement was:

> There is more brain input from vision than any other input possible

I guess we could compare the nerves that lead from the sense organs. Again from wikipedia:

> Each human optic nerve contains between 770,000 and 1.7 million nerve fibers

> In humans, there are on average 30,000 nerve fibers within the cochlear nerve

so again, at least an order of magnitude more nerve connections from the sense organs to the brain. I think this backs up the original statement.

Interestingly the number of nerve connections from the cochlear are greater than the number of raw sensory inputs, but the eye is quite the opposite. I know the input to the brain is more of a differential coding between colours than raw data from the cells.
Whenever I read about the efforts of Microsoft in and around Git, I have mixed feelings. On the one hand, it is an amazing contribution to OSS. It really conquers complex architectural problems with better algorithms and does not only polish some administrative frontend nonsense. Their blog posts are always excellent outreach documentation.

On the other hand, I feel that Microsoft is abusing git with their bloat repositories, and now they even add bloat to the git ecosystem (if there even is one). Git was initially written for the Linux kernel. The Linux git repo is huge, but apparently Windows is so much bigger then Linux that it requires a 15GB repository. I have never seen 15GB of ASCII text (code). Everybody knows that Git is not for binary blobs (images, etc). Feels like they do something wrong, but I cannot tell. Also, using a monorepo might be the wrong choice in the beginning, but since they put so much engineering effort in solve these problems at the root, there seems to be some decision why they need git exactly in this very way.
I think people are worried about the unknown unknowns. IIUC, it's infectious for a considerable period of time (one or two weeks) before the infected person becomes systematic. Plus, it's possible that some infectious persons never develop symptoms. Also, the case count is still in exponential growth mode. Plus, information coming out of China might be incomplete.

No idea whether the conference should be cancelled, but it's not an irrational idea. There could be a large number of silent cases outside of China already.
Definitely a thing in Alaska, wolves being pack animals makes it more of a danger as they can attack humans too.

Doctors scared to bring their kids to hospitals after Wisconsin baby snatch
You'd be surprised at how often it is heard when discussing this topic (edit: see comments). My grandfather used to visit Alaska and talked to them about it and not only did they just laugh when he told them that was what the forest service "down here" said, but they said "you should talk to the Siberians!".

I'll admit the statistics of wolf attacks in NA are small, but they fail to take into account many things, for example the high number of national forest disappearances a percentage of which could have been animals attacks we don't know about. Also, just from personal experience, when in wolf territory statistics are hardly a comfort when you hear the yips a ridge over...

Some have said it's fear mongering...I wonder is there such a thing as statistics-mongering?
Are you sure? Only Samsung (and LG apparently?) have the hardware feature where it tricks a magnetic stripe reader into thinking a card was swiped. However, the kind of magstripe emulation I meant is a feature of EMV where it can provide the same information as a magnetic stripe would, but over NFC, for compatibility with legacy (US) payment systems. Does Apple not support this latter system either? (It's apparently not supported for Apple Card, but Google isn't helping me for Apple Pay.)
I think it's alright to have the _option_ to keep a background service running, as long as the user is kept informed of the power impact (preferably with hard numbers). There are some use cases where it's the most reasonable option.
I'm thinking of the same thing, looking at the pictures of old phones, there should be space reserved between the "1" hole and the metal stopper.
> Third, there are often claims that wolves never attack humans, and those claims are blatantly false or are using very carefully selected statistics (North America only, etc) to craft a narrative.

This smacks of fear-mongering. I wouldn't say never, but I can count the number of wolf attacks in the lower 48 states in my lifetime on one finger. Furthermore, that one wolf attack was by a captive pet wolf[1].

Man, I come from a rural background and generally feel for the interests of rural folk, but these wealthy ranchers really grind my gears with their entitlement. ‘How are we supposed to ranch and maintain our way of life when the government makes changes’—like using the countryside to pasture livestock as they’ve ‘done for generations’ is an inalienable birth right. Give me a break, everyone has to adapt with the times, ranchers should be no exception. For all their ruggedness they honestly act like spoiled children. ‘Wolves will affect the livelihood of my archaic, wealthy rancher lifestyle’ doesn’t really reverberate with me. Suck it up buttercup.
I agree completely with your first sentence. I feel like when reading history, though, there is what happened, and there is the story about what happened. Sometimes it's basically impossible to have one without the other, but sometimes it's not, and I think what's compelling about Graeber is the story he tells about debt, but it didn't feel to me like he tried very hard to disentangle his facts from how he felt about them. But like I said, I do need to read the book again.
and done by one of the founders.

But github despises its own 2 founders. As it grew, culture changed and founders became enemies. So it became better to write a new tool rather that cooperating with some people.

Hub has been in development since 2009, for sure the gh team could had cooperated.
Given both are open source, neither of them is going to be able to leapfrog the other for long, at least in terms of core C/C++ language features, without the other copying and implementing something similar. Both have sufficient developers to keep up with the pace of development. What's more interesting, at least to me, is what impact this competition is having on the wider ecosystem. Is it leading to more features and better compilation than would be the case if there was just one compiler toolchain?
They might not, that is why I am asking. Maybe prevention of poaching would pay for the system? Maybe they get a discount on insurance? A sheriff or other agency could tranquilize and tag the wolf, then relocate it. It would be great if some ranchers could chime in.
Fictional. Exactly.
The Hail Mary Cloud and the Lessons Learned (2013)
Zero accidents in 200k miles, so "tragedies avoided" was probably the wrong way to put it. My point is: for every one tragedy, there are hundreds of little ways Autopilot makes everyone on the road safer.
They're worth effort, but the answer is that the parameters area reasonably well known. Suicide isn't increasing exponentially, for example.
Appreciate your input. As somebody with a house near a Colorado National Forest, I can corroborate that it is over-choked with fuel and a fire catastrophe waiting to happen. Not burning for decades will do that. As for the wolves, I think you have to offer something more around your wolves-attack-humans point. I've only seen statistics that say otherwise. What data are you drawing your conclusions from?
Too bad this doesn't work with Github Enterprise :(
MWC got caught in a tough spot. Lots of companies were pulling out. Companies don't like sending employees to events when, rationally or not, a lot of families are going to be uncomfortable about a family member traveling to a big show with a large number of Chinese attendees. And, of course, a lot of employees also believe, rightly or wrongly, that they can't just say "nope" without consequence.

Many years ago, I remember my company canceling some sales event because of, I think, Gulf War I because they didn't want to tell European employees in particular to travel to the US often on American carriers.
>There's a core there that does transcend "the historical and cultural milieu of its origination," but you kinda need to tether the text to its milieu to find it.

Strong agree. Clausewitz has a whole Chapter on billeting armies. The advice presented is mostly of use to historians. Not everything he wrote was timeless. Applying a work in a modern context involves understanding its limitations and the context in which it was written.

Why did Clausewitz think X? If X is still relevant today, is it relevant for the same reasons that it was 200 years ago?

Does this idea X truly transcend time, or are there just many important similarities between our time and the time of Clausewitz?
The problem is that stock Android on Essential will no longer receive security updates. LineageOS will receive updates, but if you want to use things like Google Pay or Netflix, you'll have to install kernel mods to trick SafetyNet into thinking that it's not running LineageOS.

I'm almost OK with doing that, but I think it's a tall order my partner (non-technical) who has been using an Essential.
$50k is $250k with a 5x multiple (not uncommon for SaaS businesses), and $500k at 10x multiple.

It's noteworthy that relative to expenses, this business is profitable.

It's also noteworthy in that many businesses never achieve profitability.
Do you have any citations for that? The answers to this Quota question: https://www.quora.com/Is-the-land-used-for-Israeli-settlemen... say all the land was bought from landlords (who of course may not have been the people living there) or was registered as public land under the Ottomans.

Which is still an unfortunate situation for the tenants, much like being evicted in San Francisco after your landlord sells your apartment to someone else, but still different from outright theft.
That's great. I didn’t know that all the gTLDs are blacklisted, I thought they only the first 100k. This should make the transition smoother
It is tough but I've opened up a couple to replace a broken display. They are difficult to put back together well, but it's doable.
There should only be one using/try catch block on the highest level. All of the methods being called within that using block should just throw errors.

You could put the logic in attributes but I don’t consider a transaction a cross cutting concern. It would create a spooky action at a distance situation.
I have heard that it is good practice to always chose the number of teeth of two gears to be relatively prime. This is because there can be impurities in the metal, and if you have a small part of a tooth that is harder than the rest it will erode the opposing gear (there is always some friction going on). By choosing the number of teeth to be relatively prime, the wear and tear is distributed uniformly on the gears, and thus they last longer.
The car had LIDAR. It wasn't an equipment failure, it was a failure on the part of the programmers. They had programmed in a hard delay to prevent erratic breaking and the system was programmed to dump data whenever an object was re-categorized. The system detected the person in the road as an unknown obstruction and properly detected that it was moving into the road but it re-categorized that obstruction 4 times before correctly identifying it as a person. By that point, the velocity and LIDAR data had been dumped because of the re-classifications and the car only had <2 seconds to stop.
Most adblockers can be tricked just by changing request URLs, but uBlock goes one step more and overwrites Google Analytics functions with `null`, so it doesn't work at all. See https://github.com/gorhill/uBlock/blob/master/src/web_access...
It's mostly used in the kanji version (積読 or 積ん読) (7m+ results).
Just out of curiosity, does the idempotency guarantee cover deliberate shopper actions, or just retries due to network errors?

Shouldn't high velocity + high amount purchases be treated as potential (friendly) fraud and blocked by some fraud system somewhere?
I was willing to believe it was real because it reminded me of a word actually used by Japanese: tachiyomi, which means "standing reading". A.k.a. what manga fans do in the bookstore, reading manga right there in the aisles and attracting the ire of the bookstore owner.
Yes, that's exactly what happened when they killed all the wolves in the first place...
The team was much larger. Engineers have more options when things go poorly.
There’s just the little problem of trustworthiness of Chinese numbers. On one hand you have this reassuring data that dynamic of the virus is slowing down, on the other there are serious people with good credentials going on record saying this might get a lot worse before it gets better. 2% CFR on 60% of world’s population is not a negligible number.
That's my point. If a company can release something without being on the hook for it, that's awesome. It encourages them to release half-baked stuff alongside their platinum stuff which is something I desire far more than having them only release stuff that's full-baked.

Simply put, I prioritize more software way more than I prioritize officialness etc.
I'm sure you enjoy imported goods in your European country no? Imported goods that were likely shipped to you via pirate-free shipping lanes courtesy of the US Navy?
Well said. And to be fair, I was talking mostly tongue-in-cheek about the "idiot", etc. I've been that guy I'm sure.

I agree about the trade-offs, I've been there myself too.

" is an "illegal" (as set by the UN but not by Israel I assume)"

They are considered illegal by US, Canada, UK, EU, and most other nations. China generally supports the notion that this is occupied territory and generally votes in this direction the UN.

So this is not one of those 'North Korea, Syria and Somalia have taken control of some UN working group' type of scenario, nor is there really any lack of international solidarity, at least academically on the issue.

Obviously it's complicated, but there's pretty much a consensus on the de-facto illegality of the settlements.

I think O'reilly has one of the biggest catalogs for that budget: https://learning.oreilly.com/signup/

You have access to hundreds of good quality books, learning courses, conferences, etc.

Now, I've seen that for the best courses fos something in particular, you'll find material from different sites, and buy them individually can get much more expensive. I've seen good courses for specific topics from Linkedin learning, others very good from educative.io and even others from packtpub so it's a big decision just to go with one.
Exactly. We built a registrar for Handshake (https://namebase.io) and our service will automatically handle renewal transactions. That said, anyone can still manage their keys and submit renewal transactions on their own if they want to do that, similar to how you can use Coinbase vs a desktop wallet for Bitcoin.
Terrorism kills 2 people per year in the U.S. and we spend 100s of billions. The difference is large companies make more money building weapons than large companies make treating the flue (or mental health).

Edit: The point is, it's all about money. There's no rational reason to spend so much on terrorism and so little on mental health, yet we do.
