In order to keep this company paying the basic bills it needs to survive, we do sell the more advanced programs at a small cost. Please understand what a 20-different-routine package, intended to cover you at least one year with new exercises each week or month would cost from a trainer at the gym, and compare at the price we sell, which is usually around 9$ (and we pay 3$ per package which goes to paying bank fees btw.)

Internal gearhubs are marginally less efficient than a clean and well-maintained derailleur system, but they're considerably more efficient than a dirty and neglected derailleur system.

while my fuel costs are nothing close to the poster you responded too, in the US my commute is 54 miles and my Volt in mild to warm weather gets this easily on one charge. I have not added gasoline to the car since I bought it in March 2017.

While I do work at home a lot I have saved a tank of gas every other week while never having to worry about range anxiety as the range extender will cover me.
Curious if anyone is using weed flowers or extracts to treat these any related issues? Some strains are known to help focus the mind.

I found using some strains help the ability to switch to a new task and focus for a longer period of time. The problem is the next hour after the body needs additional rest.

You can. You just move the motor, battery/controller to another bike.

What the author did is a great way to check the feasibility of the idea for himself without breaking the bank.
I live in Switzerland where 45km/h speedbikes are fairly popular (since for once our laws are more lax than in most European countries).

I don't really see how they're more dangerous than scooters in the same vehicle category.
> Having now gone through the experience, I would definitely recommend the build route. You just get much more value for your money.

And then there's the "IKEA effect". ;)
It'd be dangerous to pedestrians and non-motorised cyclists though.

Of course, fit cyclists can cruise at 30+. But to get to that level, you've to put in serious effort and by the time you got the power, you know your responsibilities too. But giving anybody 30km/h vehicle that is legal on shared paths ain't good idea.

If you're afraid of cars overtaking you, get a small motorcycle.

Boot Guard is implemented by the ME, in part of the code that still runs in HAP mode. But, crucially, the buffer overflow described there occurs before Boot Guard runs.
Time travel could collapse (or build) a great number of bridges and buildings.

Nuclear physics, a comparatively trivial academic accomplishment, did collapse a great number of bridges and buildings, and stood a very real chance of collapsing all of the bridges and buildings. It still might.

I can't understand why this is down-voted. Maybe this is just an emotive issue; somebadguy's aggressive comment makes me think so.

Guns, cars explosives etc are things, and it is possible to regulate their possession wrt individuals that may misuse them.

A call to the police is a service, and is not the same kind of thing since anyone might witness a crime and need to call the police, even unreliable individuals; whereas few people need explosives (esp without a demonstrable need or credentials), and depriving an unreliable individual of e.g guns or a car, is unlikely to be as harmful to third-parties as limiting access to the services of the police.
A very interesting read indeed!

Besides HN how can one find great papers like this? How did you find out about it?
I've followed this github project for the past year and a half and although I find the repository full of amazing resources, I still find it unsuitable (for my own needs) since there's limited (to no) feedback -- necessary for learning -- from a dedicated resource (I.e professor ). However , the project maintainer(s) are aware and working on addressing this -- as well as other -- issues; its worth noting that this problem isn't esoteric to this project , but many other (free) online resources .

> While that amount of power is able to achieve 20MPH range, it does take its time to get there. In the US, with the open roads, that’s simply not enough power to keep up with traffic.

If you're talking about keeping up with traffic going more than 35 MPH, then the e-bike should have its brakes upgraded. I've gone down steeper hills before on my conventional bike at speeds up to 35 mph. With my cantilever rim brakes, it takes some distance to stop (quite a bit more than a car since you're effectively limited to a single wheel and a smaller contact patch relative to a car).

So if you have an e-bike that could keep up with 35 to 40 mph traffic, you'll still have to allow more distance to brake and leave plenty of following distance.
Its a DC rear hub motor, I can throttle it fully up and still hold my bike in place. It accelerates poorly and has relatively little torque. I can get my bike up to the same speed manually with the benefit of the gearing all bikes have.

On even terrain I don't have any reason to be driving around at over 15mph (and I don't), but we do have morons who will, and that's why the law is so restrictive in the EU.
Oh but that experience would be so much worse if it were like genius.com where you see the most upvoted annotations. The beauty of reading somebody else's margin notes is that you learn something about that person not just what they have to say about the book.

But if you limited the social experience to friends, people would be self conscious about what they wrote in the margins. And some people would have friends who didn't mark up their books and miss out on the experience.

No one's going to buy your damn annotations though unless you're some kind of celebrity. And that's precisely what they'd be buying. In the used book store you're buying the book with the annotations because it's cheaper than the book without annotations, and then you luck out and the annotations are interesting. With ebooks, a second hand purchaser would be able to turn off your annotations and have the original book, good as new, so the price would be, at a minimum, the original retail price.
Writing and promoting a technical book
Just a heads up it actually works both ways. The originating depository financial institution (ODFI) can submit debits (pulls) or credits (pushes) which are then ultimately transmitted to the receiving depository financial institution (RDFI).

Often banks and credit unions will limit ACH origination to debits (pulls) in digital banking applications for risk and business reasons.

You are right that ACH (and most payment schemes in the US) have substantial deficiencies in terms of security, but that is counteracted with a strong justice system and consumer laws. You shouldn't really fear about someone emptying your bank account (unless you are a business) because Regulation E mandates that banks and credit unions make you whole for any fraudulent transaction reported within 60 days of the statement that includes the relevant transaction(s).
Ask HN: Why shouldn't existence of competent competition affect my startup idea?
I know the general advice (from HN) when considering a startup idea is to disregard competition, or even to consider a lack of competition as a sign that the idea is weak. But this doesn't seem quite right. I'd like to start a company using a slightly different business model than what others in the industry (from a very high level, it involves eliminating an efficiency in a supply chain which means I can operate at a lower margin), but what stops a competitor or even competing startup from spending a couple months pivoting to the new business model, eliminating the same efficiency, and then putting me out of business? What am I missing?
> The point of a to-do list (or reminder in Google Calendar) is that it's constantly staring at you until you actually complete it. It sounds like you're using one-off calendar entries. I'm not suggesting that "try not having ADD", just suggesting you use mechanisms to remind you to do stuff that are persistent and thus work.

No offense, but from what you're saying, it's pretty clear you don't understand how ADHD works. ADHD is a disorder that affects executive function; the whole problem is that the system you're describing will fail for someone with even moderate but untreated ADHD, let alone more severe cases.

Maybe you don't mean it this way, but it's actually rather insulting to say that these mechanisms "are persistent and thus work", or that OP try a to-do list because "it's constantly staring at you until you actually complete it". ADHD means that you can't assume that those systems work, and it means that "constantly starting at you until you complete it" isn't actually a viable solution.

Hence, that's why OP read your post as "try not having ADD", because you're literally suggesting solutions that presume that they not have ADHD in the first place.
I'm gonna throw some cold water on this and say this is not a new paradigm by any means.

However, it's certainly possible that the time for this idea has come. Google is probably in the best position to apply it.

I will say that after having worked at Google for over a decade, some of it on data center performance, there are plenty of inefficiencies that have nothing to do with algorithms or code, but have more to do with very coarse-grained resource allocation. In other words, they are "boring management problems" rather than sexy CS problems.

I should also add that you're expanding the claims made in the paper, which appears to be a common mistake. If you look at the related work and citations, you'll see that it's mostly about B-Trees, bloom filters, and indices. But I have seen people generalizing this to "a revolution in systems research", which I don't believe is justified.

Indexed data structures are important but a revolution in them is not going to cause a revolution in all of systems. Off the top of my head, the general area of "scheduling" (in time and space) is probably more important and more potentially impactful.
That's how I feel about drugs in general, but I think society has this weird split of two extremes: any unprescribed, street drug is super dangerous and evil, and any prescribed drug is just just medicine correcting an "imbalance", and is totally benign and fine and good. Madness both ways.

You mention getting prescribed in college, as a adult. How would you feel if you had been prescribed as a kid?

To me, growing up regularly taking amphetamines seems like it could twist your head pretty badly. Seems very irresponsible to be giving drugs to kids.

(I get the pressure to do it if the kid can't behave or focus and you think that's fucking up their life, but honestly, having gone through school, the fault is much more likely to lie with the school & what we expect of kids than the kids themselves...)

The obvious problem is that the dissemination of news these days is determined by how many arbitrary or ignorant individuals have clicked "like" or "upvote" on whatever social network they're using.

It doesn't need to be true, it just needs to be shocking, and people will promote it.

This is only fixed by good moderation, with prominent (and powerful) "flag" buttons like Hacker News has. Hacker News and Reddit don't suffer from nearly as much fake news, because moderation teams tend to do a good job of weeding out garbage, and have an easier time with the prominent report buttons.

Facebook and social networks have absolutely no moderation.

They accept that risk by signing on the dotted line and picking up their badge. Cops should have a policy of never shooting first unless someone who isn't a cop is in immediate clear danger. That's what we pay them for. Any bozo can shoot first and ask questions later. A trained, well-paid professional's job is precisely not doing that.
hydraulic mostly provides improved actuation via greater modulation resolution. Think about it - It's a hydraulic system vs mechanical. No cable stretch and no friction along brake housing. However greater modulation resolution is not a major benefit in the context of ebike. The bike is heavier so you just need sufficient braking power. A larger rotor radius would help more than going from mechanical to hydraulic.

hydraulic alone doesn't provide greater braking power vs cable pulled calipers.
> including the fact that driving a car is fun for a lot of people

Hmmm... Communting to work is fun for people? I want to live where they live.

Keep the car for weekend cruising, the bike probably makes the boring commutes more fun than a car would.

I built an bike 6 or 7 years ago but only took it once to work (a 20 mile commute). It was underpowered and under-batteried but it was an interesting starting point. I mean to try it again.
From the recent articles, it looks like disabling Intel ME is now the "new jailbreaking" --- something which the corporations are very much against, but which can have benefits for users. Boot Guard is just another in a long line of many features advertised for security but really for maintaining control over users.

It's sad that this battle is now taking place on the once-open PC; but given that Intel has been shown to change direction from intense negative backlash[1], maybe if everyone opposes, they will stop locking down the platform further. The problem is that there is now an IMHO extremely authoritarian "security industry" heavily advocating for these user-offensive features. (And opposing them causes you to be called a terrorist, pirate, or worse.)

> I can't imagine anything past 15 MPH for the general public is a safe thing based solely on the bike handling skills of the majority of the general public.

It's pretty easy for most riders to get to 25 MPH or above when going downhill. That's why I take the lane in those situations and keep an eye out at every single intersection.

I think a lot of the situations that you describe could be prevented by taking the lane (riding between the center and left tiretrack position of the lane you're in) to discourage car and bus/truck drivers from passing you when it's not safe to do so. It will also make you more visible to passing traffic as well as traffic at intersections.
> is the lack of explicit type declarations

This is mistaken. Rust has explicit type declarations, augmented with type inference. Furthermore, unlike popular statically-typed functional languages, Rust's type inference is deliberately restricted to only operate within functions (intraprocedural) rather than between functions (interprocedural), which means that one always has explicit types available in the function signature when reading code.
Can you elaborate on your data collection? What devices and software did you use?
I would like to try it myself :)
If all of your parts are good from the start, I agree. But if you are building a computer for the first time and get just one bad part, it can be difficult to isolate where the problem is if you don't have a box full of spare parts you know are good that you can swap out one by one until you find the bad part.
How does a persistent in-your-face reminder that does not go away until completed fail? I suppose severe procrastination or complete lack of willpower would do it, but are these not different from ADHD?
If anything it's time that's the hardest to commit, in my opinion. But even setting an hour to two on a weekend aside for something you want to do is something. Good luck to your coworker for whatever path he chooses!

Strangely enough, magnets do weaken over time, and we can show it from conservation of energy. If a magnet and paperclip are placed nearby on a desk, they will zip towards each other. This momentum has to come from somewhere. It cannot come from the paperclip, because paperclips do not attract each other, so it must come from the magnet. The magnet must therefore somehow store energy, and when its magnetic field causes motion, that motion must somehow consume the magnet's energy, even if the magnet's magnetic field doesn't appear to change.

Commercially, magnets are produced by heating above a certain temperature[0] and then coercing the heated metal's magnetic fields into alignment. Since this process consumes energy, you could imagine that the equivalent amount of energy expendable by the magnet over its lifetime is bounded by that process. This might seem silly, but it has some corollaries which we can directly experimentally observe. For example, a nail gun correctly oriented relative to the Earth's magnetic field will temporarily magnetize ferromagnetic (steel, usually) nails while the nail is in motion, by the same sort of domain-alignment process involved in permanent magnetization. (Please do not do that experiment without taking proper safety precautions. Maybe we can talk Adam Savage into doing it for us.)

In terms of calculations, we can use the "demagnetizing field"[1] but I think that it is not a very good name. Nonetheless, it does show that any time that there is a strong magnet, there is an automatic effect which will slowly slowly slowly weaken it.

More generally, any maintenance done on a machine violates the closed-system assumption. You'd have to include the cost of maintenance if you wanted to show that you're violating thermodynamics. Because magnets are so long-lived, they might seem perpetual, but they are not. They are finite energy stores and they do run out eventually.

(Disclaimer: I've studied pharmacokinetics, though I'm not a pharmacologist)

Vyvanse is a prodrug. That means it metabolizes into the d-enantiomer of amphetamine, whereas Adderall contains a 75-25 mixture of the d- and l-enantiomers. (Enantiomers are like left- and right-handed gloves: they have the same chemical structure, but one is the mirror image of the other. Usually two enantiomers will have similar but slightly different effects; occasionally, they can have incredibly different effects - see thalidomide for an example).

So, without further study, it's hard to know, but it's likely that Vyvanse has a similar long-term profile to Adderall, because the active ingredient (lisdexamfetamine) metabolizes into the active ingredient that makes up about 75% of Adderall.

But, it's possible that the effects described are caused by the l-enantiomer, in which case they won't apply to Vyvanse. It's also possible that lisdexamfetamine itself has its own set of effects which may either cancel out or exacerbate the effects reported by Adderall.

To give you an idea of how prodrugs can have different effects from the drug that they metabolize into: Vyvanse does have a rather nasty feedback loop for some people, because amphetamines suppress the appetite, but lisdexamfetamine is metabolized into the active ingredient using the digestive cycle[0]. For some people, this can cause a really wonky extended release cycle, where they have no appetite mid-day (due to the drug) and can't eat enough to metabolize enough dextroamphetamine to get them through the afternoon, resulting in an afternoon crash. After this wears off and they develop an appetite again (around dinnertime), they'll eat, and then the dosage that was supposed to kick in after lunch finally kicks in after dinner, causing issues sleeping.

[0] This is intentional, and it's why Vyvanse is marketed as an "abuse-resistant" alternative to Adderall, because it's theoretically harder to extract an acute dosage from it.
