Fair enough. I do see how you could think that it's intuitive. I've even used your explanation when I'm teaching. Although I can't help but think there's some sort of circularity going on here, at least for me. My intuition on the subject is shaped by my knowledge of the theorem, and the functions that I tend to work with.

> the main reason why skateboards are worse injury wise is many of them try to do tricks constantly

Surely it's simply because of scenarios like a small rock's ability to insta-stop your board, basically guaranteeing your injury. Pretty much every time I've ever been knocked off a skateboard during my commute would be something you wouldn't even think/care about if you were on a bike. Not even close. One is a bike, the other is a heavy, tall pole (you) on a low, rolling platform. One is far more precarious, like keeping a reverse pendulum balanced.

Hell, the most common injury I've seen on a skateboard is just someone stepping onto one, misplacing their center of mass, and the board just rocketing out from under them, and then bruising their tailbone/wrists. Even an inexperienced bicyclist doesn't have a fail case close to that.
The Dangers of Hacking and What a Hacker Can Do to Your Computer
How Hackers Operate and How to Protect Yourself

People, not computers, create computer threats. Computer predators victimize others for their own gain. Give a predator access to the Internet — and to your PC — and the threat they pose to your security increases exponentially. Computer hackers are unauthorized users who break into computer systems in order to steal, change or destroy information, often by installing dangerous malware without your knowledge or consent. Their clever tactics and detailed technical knowledge help them access the information you really don’t want them to have.

How can hackers find me?

Anyone who uses a computer connected to the Internet is susceptible to the threats that computer hackers and online predators pose. These online villains typically use phishing scams, spam email or instant messages and bogus websites to deliver dangerous malware to your computer and compromise your computer security.

Computer hackers can also try to access your computer and private information directly if you are not protected by a firewall. They can monitor your conversations or peruse the back-end of your personal website. Usually disguised with a bogus identity, predators can lure you into revealing sensitive personal and financial information, or much worse.

What are things that a hacker can do to me?

While your computer is connected to the Internet, the malware a hacker has installed on your PC quietly transmits your personal and financial information without your knowledge or consent. Or, a computer predator may pounce on the private information you unwittingly revealed. In either case, they will be able to:

Hijack your usernames and passwords
Steal your money and open credit card and bank accounts in your name
Ruin your credit
Request new account Personal Identification Numbers (PINs) or additional credit cards
Make purchases
Add themselves or an alias that they control as an authorized user so it’s easier to use

I've been using this with my team for about a few months for production level systems. It's been great for what it does. The real time traffic viewer is a handy tool for our day to day use and having the automated anomoly detection means we don't have to manually go track every request/response and be flooded with noise.

Think of all the marketing opportunities there are in this sort of evil. It's so positively lucrative.

You could televise drone camera footage and have bets on which drones shoot the most fleeing brown people. You could have an e-sports league, but instead of playing Star Craft you could have nationally recognized "players" manning the drones. People would fill stadiums!

You could even, with a little thought on the tech stack, have machine gun turrets that the public could operate for $20 for 20 minutes. Hell they could do it through the internet from the comfort of their bunker. So long as the turrets were pointed south there wouldn't be any risk of any of the "important" people being killed.

Truly this is a visionary whose time has come.

This is how I think of it too, and it makes some part of me want to believe that means I have an intuitive grasp do what’s going on. Except I don’t think that’s how math works. Rigor is necessary because an intuitive hand-wavey understanding is often wrong. I think there’s just as convincing a hand-wave available that dismisses the idea.

1) We have one point of the function.

2) We know one point of its derivative. We still don’t know any other points of the function.

3) We know one point of its second derivative. We still don’t know any other points of the function or its derivatives.

...

N) Same deal.

N+1) Same deal.

...

Inf) Now we know all the points in the function and also all the points in all the derivatives.

It looks absurd like this. Not to mention that we start with a countable set of points and derive a continuum from each.
If you want this where you live and people are telling you it costs too much ask them to itemize the cost of the fare gathering machinery, all the accounting and cash handling/data processing, the cost of enforcement etc., and then subtract all that from the budget.

I think the problem is that you would have to park your car out in the sun. The sun is hard on cars.

Hot temperatures are not great for batteries, and if there is ever any active thermal management, the costs would subtract from the benefits.

Elon Musk talked about this a couple of times. At first they explored it, but then said cars wouldn't be outdoors enough to benefit.

I have wondered about solar panels on the top of trucks however. A 53' trailer has 450 square feet of roof, which with standard panels works out to be 6kw. Probably much more with the panels toyota is using.

It seems the Tesla Semi specs say "less than 2kwh per mile" so 3+ miles for each hour of sunshine, more with better panels.

Ask HN: What do you think will happen to the Gig economy with the bill?
Please give you thoughts on what will happen to Uber, Lyft, DoorDash etc. with the new bill that’s being passed in California.

This bill would require these companies to treat their contractors as employees - providing health insurance, benefits, etc. Completely killing the low on demand labor they currently benefit from.

What do you think startups that are relying on contract / on-demand workers should do?

Shameless plug - I’m building Shopr. A marketplace that connects online shoppers to nearby apparel stores to get their items delivered within 2-hours (vs. the typical 2-5 day shipping). Our model uses contract drivers to fulfill the orders, which is why I’d like to hear your opinion.

> Remember there already is a mature C compiler alternative for Go: gccgo. There's also already a first-party LLVM based Go toolchain created by Google (gollvm). Whatever hypothetical benefits you might presume would emerge from this kind of synergy already exist. But the community mostly isn't interested.

I suspect the community is uninterested because it’s hard to be interested in compilers that a) compile slower than gc, and b) produce slower code than gc. That's a worse compiler on all fronts!

For gccgo or gollvm to be useful, they need to provide some benefit. I suspect we'll see (b) fixed within a year. GCC/LLVM have far more optimizations than gc, and so it's mostly a matter of plumbing enough information from the Go frontend into the LLVM optimizer to unleash its full power.

I don't expect we'll see (a) fixed, unless something changes at Google.

> Also, Google also already invests a massive amount of resource into LLVM. In fact, the principal author of LLVM and Clang works at Google. But even when he was at Apple they were already shoveling resource into the project.

Yes, but Chris Lattner is not actively working on speeding up LLVM. His big project lately has been supporting TensorFlow via MLIR.

Don't know about the UK but in Italy the law is that (traditional) bicycles don't need any registration and helmet, ebikes are the same but the engine must be on only if the rider pedals and shuts down at 25 km/h. If not, it's a motorbike and needs driving license, helmet, registration and insurance. After all who cares if the engine is petrol or electric.

Escooters are about to be regulated. They should be motorbikes IMHO, but the slower speed and the way people use them make them something different. After all we want less cars around and escooters are a way to that goal.

But please, ban them from sidewalks. Having something fast moving among pedestrians is dangerous. Same for bicycles (and I'm a cyclist), only bike lanes and roads. Furthermore sidewalks are full of obstacles and have way worse pavements than roads.

> The recidivism metric would probably cause private prisons to try to avoid or eject worst prisoners, so you'd end up with a 2-tier system, where private prisons are hotels for "nice" people, and public prisons are a hell-hole for the rest.

Yes, so you'd have to run the metric based on who was initially assigned to the prison. "Oh, John was assigned to your prison, but one look at his record and you decided to expel him? Well, you're still responsible for his recidivism, because you chose to not serve him. Oh, Jack was assigned to state prison, and you tried to encourage him? Well, you're not responsible for his recidivism, because you selected him."

But yeah, I agree in general that the thing about metrics is that they can be gamed.
Starting from C++11, yes.
Let's just let each other be excited about our favorite math, okay?

I don't think it's malicious, we're just trying to narrow down exactly what makes something interesting. In the process, we get to understand our favorite math more deeply.

Nothing is surprising if you've seen it before.

On the other hand, if you can find a theory that makes a miracle look mundane, then the theory is probably interesting.
So finding reasons why something is `not surprising' is a good guide to finding interesting math.

> I figure if California's prisons were 200% of capacity, there's no shortage of work for the prison guards anyway.

I'm not sure how/why you figure that, or how it's at all relevant.

I'm not sure how/why you figure that because "over capacity" != "will build new prisons / hire new guards". I.e., it's not at all impossible for there to be prisons that are over-capacity and also a decline in the number of prison guard jobs.

It's not relevant because the entire point of unions is to counter-act the effect of supply/demand dynamics on labor (see: "there's always another scab"). Just because there's "no shortage of work for the prison guards" doesn't mean they will lobby against changes to laws that might one day create such a shortage.

But he wasn't compiling the Lisp! So this compared GCL's Lisp raw AST interpreter to Python byte-code.
> Algorithms can actually produce a real physical result, whereas mathematics exists beyond pen and paper

You are confusing the algorithm, which is an abstract procedure with no physical existence, with the set of possible processes that can implement it.

> Algorithms that we (programmers) construct usually aren't done in terms of Turing machines or the lambda calculus. Therefore they're not purely mathematical

Sloppy math is still math. Any program that an interpreter or compiler will accept is a mathematical object. If it weren't, it couldn't be parsed. That said, it is possible for a mathematical statement to be undefined, ambiguous, or erroneous.
To be fair you must balance it against the costs to administer paying for the "free" service, i.e. cost of collections via taxes or whatever, allocation of resources via some contingent of petty bureaucrats, disbursement via whatever system of adminstrators that are required to keep the books, and enforcement to guard against cronyism, cooking the books and other sorts of corruption.
