I don't have any numbers, but my impression is that it's mostly turns, although there's also a big problem with people getting "doored" (which would easily be solved by putting bike lanes between parking lanes and sidewalks, instead of between parking lanes and automobile lanes).

I was surprised to learn that left turns account for "more than twice as many serious injuries and fatalities as right turns." https://www1.nyc.gov/html/dot/html/about/leftturnstudy.shtml

And that all the examples given of uneducated masses distrusting statistics just happen to align with the Guardian's pet causes is of course pure coincidence.

Really, that's the perfect example of why statistics are distrusted - only those statistics that align with someone's agenda get presented. And sometimes, they're not even gathered in the first place: https://www.thelocal.se/20180508/why-sweden-doesnt-keep-stat...

I see you mention circuit breakers.

I think they deserve more thorough coverage because 1) you really need them in a lot of applications, and 2) they're not in OTP, so picking one (especially if you're not really an Erlang expert) and employing it in the right way are a bit trickier.

A simple example of an application that probably needs a circuit breaker is a web application that can keep running even if the database is not available, even if all it does is return an error message to the browser.

I'm not sure what the distribution is, but definitely both. I've been hit in an intersection, funny enough, by a police officer, who just turned right, crossing into the bike lane, t-boning me. A few months ago, I saw a truck completely just run over a bicyclist, killing her on 6th ave, and not even stop [1].

Often times, protected bike lanes are still very unsafe. 6th and 1st Avenues are a prime example, where trucks park to the right of the bike lane, and unload in the bike lane, forcing cyclists to suddenly merge into aggressive traffic.

> 3. binary trees are almost worthless.

Interval trees reduce to Binary Search Trees when the nodes can't overlap. Most markup DOMs (in browsers, WYSIWYG editors, etc.) are held as an Interval-tree ADT which is actually implemented by a BST.

Also, Red-Black trees specifically are used in many database clients to implement an in-memory write-back cache of a database table, as the combination of performance requirements for flushing batches of writes to the DB, and reading back arbitrary keys that were written to the cache, make these BSTs nearly optimal for this use-case.

But yes, DBMSes themselves don't tend to use BSTs for much. Maybe as a query-plan-AST term-rewriting-phase ADT.
>The first claim is that Google is going to redirect user DNS traffic to Google's own DNS or another DoH-compliant DNS provider. That is incorrect. Because we believe in user choice and user control, we have no plans to force users to change their DNS provider. [...] We’re simply enabling support in Chrome for secure DoH connections if a user’s DNS provider of choice offers it.

Chrome will use the DoH frontend of the DNS server of the computer it's running on, respecting the user's choice. Instead, the Mozilla Corporation has decided that Firefox will route all DNS requests through CloudFlare regardless of user settings.
Quantum Theory from Five Reasonable Axioms
not to go all "blame the victim" here, but one thing I noticed culturally in NYC is that traffic lights are a suggestion to pedestrians. If there isn't a car directly in front of them, they'll cross the street.

Compare to LA, where people tend to wait for the signal to cross pretty consistently. That said, LA still has horrible pedestrian death statistics so who knows how much that matters.
That is the exact opposite of what Section 230 does.

Section 230 allows platforms to make moderation decisions while retaining legal immunity for the user created content they choose not to moderate.

However, this is currently being threatened by republicans in the senate and Facebook is trying to avoid them taking steps to reduce the scope of 230 (which was already weakened recently by inclusion of a sex trafficking exemption).

ICBMs can do that too; the MIRV capable ones carry enough delta-V when stripped to a single warhead for orbital insertion and ejection, albeit on crappy trajectories. That's why you can repurpose them for generic satellite launches. Parking a nuke in orbit violates the Outer Space Treaty though so countries don't (publicly) do it.

The thing with a shuttle is it's easier to stealthily violate the treaty than launching a bunch of suspiciously poorly built cylindrical tubes and calling them defunct space telescopes.
I never understand this kind of comments. Is there a reason why OP should have bad intentions when writing the comment? The article is about Apple not providing sufficient documentation for their APIs and OP wrote about a experience that supports reasoning why Apple seemingly is not focusing on delivering documentation.

So how about giving reasonable arguments why OP probably had rounds that went poorly and is salty about it and why Apple has a wonderful software developer culture that focuses on quality instead of assumptions? Apple has problems with documentation since years, one example I had to deal with recently: their maps API. The MapKit programming guide is still in Objective-C, old design and outdated.
Last movie I saw in theaters was a markedly worse image than what I get at home: overly dark (2D->3D lens?), yet still some scenes washed out to white. My 1080p DLP projector onto a 10' white vinyl screen seated ~5' away is better than any picture I've paid for in the last 5 years. Though, I haven't seen an IMAX in a long time: the sheer field-of-view and bulb intensity are unmatchable in my house.

Audio at the theater was better, but I haven't invested much beyond a 2.0 setup.

At $11/ticket (pretty normal around here), the break-even point is ~200 movies. You have to B-Y-O-BluRay but at least you can rewatch those for free.

The problem here is not so much Facebook (a company doing what companies do) as it is the regulatory system they fit in. This situation is unprecedented, as no single company had ever concentrated the media power Facebook has. Our legislators are barely starting to understand the problem, the ball is in their court really. In the meantime, Facebook will sit at the intersection of what's best for the company and what the law allows.

American drivers (especially in places like New York) generally just ignore 20MPH speed limits (~=30km/h).
My experience is similar. The speed differential is terrifying when you must leave a protected bike lane (which, in practice, is often).
I guess the point is that, when the statistics support their political bent, they decry people questioning the validity of them, and consider not blindly accepting them as being proof of the idiocy of the reader.

But, give them statistics that go against their pre-ordained narrative, and suddenly it is the reader who doesn't immediately refute the statistics who is the uneducated rube.

One thing I like about the newer NYC bike lanes is they put them inside of parked cars. It means you’re generally protected from traffic by a row of parked cars. And there’s a large enough buffer that you don’t have to worry about getting hit by an open door.

They don't. If I make a change that prevents a death you will never know about it. If I make that change in response to a death you will hear about it, thus biasing you into thinking I don't care until there are no deaths. In reality though sometimes you need an actual situation to happen before you can imagine that failure most. Trying to guess how your widget could kill something before their are any deaths is hard. (in some cases you can look at existing widgets, but there is always something new)

Anyone who has written a technical book knows that in general they cost a lot in terms of time and don't generate great returns. The best case is probably if it boosts your consulting income or something to that effect.

I've never met Fred, but I feel his book "Learn You Some Erlang" is clearly in another category: it's a "labor of love". I can't speak to his precise motivations, but the book is so rich and thorough, that it's clearly something he worked way harder on than would have been strictly necessary just to whip out a quick book establishing himself as an Erlang Expert. Maybe it was "the Erlang book he wished he'd had when he got started"?

As such, it's one of the few tech books I've bought, and done so quite happily, in recent years.
Yeah, so for $1100/mo I get:

- Insurance (1K deductible)

- Unlimited vehicle swaps

- 1200 miles/mo

- Each car comes freshly detailed and is usually under 3000 miles

- Unlimited (local) roadside assistance swaps - eg if I get a flat tire they will come swap me out into another car and I just drive away - this happened to my wife and it was amazing to just grab and go

- Allowed to put pets in the car (extra $100/mo)

As I have customers I drive around in-town frequently, I always need to have a nice, modern, clean car on short notice. The cars so far have been BMW m240i, Audi S3/S4, Audi Q5, Land Rover Discovery.

I feel it is worth the cost. My BMW lease before this was $700/mo. And then add in insurance, detailing, maintenance (tires). It is about the same honestly. I just have a lot more flexibility now.

Also it is a monthly operating expense, which makes the tax situation a lot easier (versus lease/purchase and then reflecting that on taxes).
A hypothetical example would be one person spending a week or two setting up an extensive in-house Spark cluster to solve a problem that a second person in one day realizes can be solved on one machine using some clever shell scripting tricks. The former person knows a lot and may have been fully capable of the solution the second came up with, but they followed the wrong guiding principles in analyzing the problem and arrived at a solution of considerable complexity.

An alternate formulation of this would involve the second person above arriving at a new job, observing that they're using Spark on an expensive cluster to regularly perform a computation, and noticing that actually they could do the whole calculation on a single node using simpler tools.
In my experience, cars actually go pretty slow in NY (Manhattan at least), even when there’s not a lot of traffic. I’m usually able to easily keep up with traffic on my bike.

>If you leave the dealership with your new vehicle, and decide to go run over 10 people, the dealer is not on the hook for your actions. Same with gun stores not being held liable for gun owners.

That is not true of the law. If a gun store sells someone a gun, and the store owners knew or should have known you intend to kill someone with it...they gun store is most certainly liable.

Even when the gun store wasn't aware the buyer intends to shoot someone, the gun store can be liable if it was negligent in the sale, like this case where KMart sold a gun to a drunk person who shot a woman, KMart was found negligent and liable for $12M
So I think we settled the "tax" question. It is not a tax after all.

> The dangers came into focus this year after 25 cyclists were killed on city streets — the highest toll in two decades.

The "highest toll in two decades" gives some context, but I wish writers would share ratio metrics rather than absolute numbers in cases like this. I.e. the number of active cyclists on the road might be outpacing the deaths, but we don't know when you just say "25 cyclists were killed in 2019." Also, how does that stack up to the number of pedestrians killed accidentally, etc.
Contributors wanted for python project, autostack – debugging tool
Hey guys/gals,

I am looking for contributors for my project, autostack. autostack is a command-line debugging tool that captures raised python exceptions, automatically searches stack overflow for an answer to the exception, and displays the answer in the console with syntax highlighting!

I actually entered this into a hackathon (CrimsonHacks 2019) and placed top 5. However, I am now looking to expand this to other languages besides python, add smarter Stack Overflow queries, and even create VS Code and Atom extensions.

Literally anyone interested in this project can start making changes and submitting pull requests. After a few contributions, if you'd like to become a collaborator, that's a possibility too! Not to mention that this project is definitely beginner friendly!

Checkout the repo at https://github.com/autostack-team/autostack! Looking forward to hearing from you guys!

One downside of these hardcore milsim games is that the companies that make them are garage shops and it is far from uncommon for bugs like this to fester for years, or even never be fixed. On the flipside, sometimes the bugs are hilarious, like third cousins in Crusader Kings that murder themselves and then have to run away because they are kinkillers.
I've been generally happy with Xiaomi Mi Band. I used a Mi Band 2 for a couple years until it died and am using a Mi Band 3 now.

My biggest need was for a "silent" wakeup alarm since I get up so much earlier than my fiance. It does sleep tracking and a lot of phone features that I don't use.

The two biggest wins are (1) the price, and (2) the battery life. I paid like $40 for the watch, and $20 for a better band on Amazon. The battery on my MiBand2 lasted ~month and a half. The MiBand 3 is shaping up to be much less, but still 3-4 weeks between charges.

>That is not true of the law. If a gun store sells someone a gun, and the store owners knew or should have known you intend to kill someone with it...they gun store is most certainly liable.

This is why literally the next line I say after the KYC/background check. Obviously if a guy sells a gun to someone without doing the proper checks they will be liable. Same if a dealer sells a car to someone without a license.

>Same with gun stores not being held liable for gun owners.

There may be background checks in place to ensure they aren't selling a car to someone that can't drive (Driver's license) or to make sure someone can own a gun (Background check), but once you pass the initial screening you are on your own for liability.

>Political ads should be the same, basic KYC to verify the person buying the ad is who they say they are or allowed to represent an entity, but beyond that anything they want say let them say it, let the public scrutinize it, and let their ideas be debated.

If people don’t follow traffic signals it is the fault of the signals. That is, if everybody makes the same mistake, it is no individuals fault, but a fault in the system.

To give a more concrete example. Say a traffic light has a pedestrian light attached. It will only allow pedestrian crossings when it does not stop the flow of vehicular traffic (say every 3-5 min, and only for 20 seconds at a time). But it does so regardless of actual traffic (no cars are passing the intersection when many pedestrians arrive), you can’t really blame the pedestrians of ruling this system as stupid and opting not to follow it.
I'm not ashamed to admit this was entirely new to me. I've been listening to the wrong people.
