This! I was a semi-professional (CAT 1/2) racer in college and routinely road in the 22 to 30+ MPH range. 30+ MPH is surprisingly easy on busy roads with a good draft coming off traffic. A day wouldn't go by while riding in the city that I didn't have a close call with a car and in fact a bus hit me once while passing me on a corner (the driver cut the corner, going over the white-line). In order to not die I did a lot of accident avoidance training and in fact this was something our team routinely pushed as part of our training. We'd focus on one particular aspect each month like learning how to crash by renting out some time at a gymnastics gym (foam pit).

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. I literally put hundreds of hours into developing top-level bike handling skills that 99% of the population will never reach in order to ride quickly because once you reach a certain speed threshold, the threats (drivers not expecting you) and risks (more kinetic energy between you and the ground and you and a vehicle) go up significantly.
I'm curious, if someone finds a vulnerability in your algorithms somewhere, will you be able to quickly deploy updates to all the installed smart meters? Because, honestly, "taking security very seriously" doesn't mean anything anymore.
This article is stupid. If solar powered anythings weren't operating from batteries then they'd stop working when the sky becomes cloudy.

Gasoline engines operate from batteries too.

The premise of the blog post is so incredibly stupid that I am forced to question the intelligence of the author.

For that matter why was it posted to HN? It doesn't offer anything of real value, is this karma whoring?
The 25km/h limit is why I won't buy one. Pointless for normal use.

>That wasn't in XX century however. They were universally gone by mid-century.

Mostly because of those pesky Bolsheviks being a new worry of the colonial powers, standing in as an idea that their rule can end, and socialism inspiring all kinds of anti-colonial national revolutions (from Vietnam to China, and from Africa to Latin America). So, there's that.

Besides, neo-colonialism still dominates the developing world. It's the bigger fish like India, Japan, China, Brazil and a few others like Indonesia, that got away from it and managed (more or less successfully) to take their fate into their own hands instead of being played and meddled.

Could you tell us a bit about the reñevance of this work?
>I mean, I get that we are discussing ADHD here, but you could have at least read the next sentence

Being condescending, especially towards people with a disorder, doesn't serve anything.

Worse, people with disorders have to deal with this stuff all the time from other people. <To someone they know has depression, in front of the circle of friends> "Hey Peter, haven't seen you in a few weeks. Were you being sad again? ;D"

It makes me cringe a bit to see that behavior here.
An excellent example of how ridiculous applying financial thought to everything can be.

As a dane, having Greenland as part of the kingdom is as natural as being able to see with two eyes. It may not serve a essential function in my everyday work but it would feel as a unconditional loss to me if I gave it away for any sum.
You really can’t rationalize it, but for a nation that once was the superpower of the north, Greenland as the very last reminant of the empire is not something we will give up freely. The obivious (and slightly heartbreaking) exception is to give it up to the Greenlanders themselves as is being done gradually.
Yes - but lets step back and think about what we can do to prevent these things from happening.

TWO things went wrong here. Not one. The criminal who made the fake call was to blame and the police officer who shot an innocent and unarmed occupant is also to blame.

There will be always crazy pranksters. We have laws to prosecute them but they can be out of country, so we really cannot fix that.

But we can fix the second thing that went wrong. We can ensure that police is trained not to kill wrong person in hostage situations (i.e., it could be that there was some hostage situation but person going out was the actual hostage).
Buy or adopt a dog. Your solitude will vanish instantly and perhaps you will interact with your community in dimensions unrelated to work or career (like meeting other dog owners when walking your dog or being sued by your neighbor because of her barking).
Police violence is a universal problem. A Harvard study has shown that white people in the US are statistically more likely encounter lethal force from police than people of color [1].

"Currently they're supposed to be happy to make do with devices developed in the 1930s."

Legs are billions of years old and wheels where invented thousands of years ago. Yet we still use them were they remain most effective. No doubt there is room to improve mobility options, but cost and battery capacity are very real constraints. And sometimes mimicking nature too closely is less effective; i.e. planes without flapping wings.

All that to say the web was born more accessible than magazines. It's probably more effective to maintain that semantic heritage than make machines that can translate flattened images like an interpreter. Still, experimentation is great. Nothing wrong with trying to make the machine. I just wouldn't advise that the whole web forget accessibility because the tools _should_ already exist.

> That's certainly one thing I don't miss about old DOS gaming, having specific boot disks around with the proper config.sys/autoexec.bat magic to make ornery games work -- base RAM, HMA, EMS, XMS etc..

You could make menus items in the config.sys to chose between different options, you did not need several boot disks. I don't remember in which MS DOS version it was introduced (perhaps 5.0?), but that was the normal way to go after that.
I still find the effort at self-examination this team underwent to be heroic, especially considering the public pressure. This, to me, represents the very best science - work that goes to extreme lengths to find their source of error.
I also completed my first 100 miles on an ebike this past week, on a bike I bought two weeks ago. I splurged and bought a top of the line pre-built[0]. Call it a mid life crisis.

It is a class three bike. The electric motor will only activate under 28mph. There is no throttle, the motor multiplies your pedal force by 55-200% depending on the setting (eco-turbo).

I can beat the bus on a few bus routes. I use to take the bus if the route had too many hills but now I maintain 17mph without getting winded on steep hills. An electric shortens and flattens any bike trip, I'm never sloughing up a hill, and I'm never asking myself if it's worth riding the bike. Even if bus or uber is faster it wont be twice as fast. Biking is still fun and still a workout, I'm a out of breath with sore legs after a ride.

I'm sometimes self-conscious about 'cheating'. I'm not sure how fast I should be going on a mixed use bike path. I'm afraid this bike will get stolen one day, even with a ulock and cable. If not stolen, vandalized.

I think that electric bikes could be the future of city transit if the price comes down. Secondary problems include theft and weather.

No, that doesn't, in itself, say anything about the degree or quality of scrutiny. It just says the events are so rare, they're memorable. Officers discharging their weapons are reviewed in the US as well.
A fast e-bike would be dangerous, anyway. At that point, you should just get a small capacity motorcycle or a scooter.
> We should also ban other dangerously addictive activities, such as fiction books, non-video games, sports, DIY hobbies

These can be addicting too, but certain video games can be on an entirely different level, ie. they fulfill many more psychological needs.

My bad -- the name "IRON HORSE" threw me off. Still, the thing supposedly weighs 37.75 lbs., which is terrible for a bike. For $1500, he could get something with much better parts weighing 20-25 lbs.

I don't think it's reasonable or effective to entirely expect police to solve this problem. Here is the account from the article:

Livingston said when the door opened, officers gave Finch commands to put his hands up and walk toward them. He complied for a "very short time" and put his hands back down. He raised them again, and then lowered them for a second time, Livingston said.

"The male then turned towards the officers on the east side of the residence, lowered his hands to the waistband again, then suddenly pulled them back up towards those officers at the east," he said. "The officers on the north side of the street feared the male pulled a weapon from his waistband, retrieved a gun and was in the process of pointing it at the officers to the east. Fearing for those officers’ safety, the officer on the north side fired one round."

From my perspective, they are describing a very threatening movement. Stuff that looks like that is how officers die. Asking them to not react when someone does that puts them in pretty serious danger. A sudden movement like that is how gunfights start.

It's tragic that it's also something a panicked innocent citizen might do! But that doesn't change the fact that it's a genuinely threatening thing to do.

I think probably the most effective way to solve the problem would be to make people better aware of what makes you appear threatening and non-threatening in a confrontation.

Some of us have been insulated from violence for so long that we don't know what it looks like. We have no reason to know that innocent sudden movements can just like dangerous sudden movements.

I'm not saying the guy's death is his fault. The whole thing is a tragic misunderstanding between good people. But I am saying he could have been educated to prevent it. I don't think it's realistic to ask police to solve the problem at great risk to themselves when regular people can solve it by learning that the best way to avoid misunderstandings and snap reactions is to move slowly and deliberately in any confrontation.

I’ve long held the belief that ADHD is wildly over diagnosed (in the US, at least).

Your anecdote has helped solidify this belief. 8/10 Adderall users I know are able to concentrate and complete complex, intricate tasks without the pills. The pills just put them in jet-speed mode.

It sounds like you truly have ADHD and are benefitting from proper medication. I wish nothing but the best for you.

However, I also wish the doctors would remove their heads from their ass and attempt to find a better method of diagnosis.

During my friend’s 3rd year of study at University, he realized many of his classmates were taking Adderall. Not only that, but those students had less trouble completing the crushing work load on time. So, he visited the local pill dispensing psychiatrist and walked out with his very own prescription.

Now we’re here, several years later, and he’s convinced that he really does have ADHD because the doctor keeps renewing his prescription. He chooses to forget that he initially got the prescription by regurgitating bullet points out of the DSM.

This is just one example. I’ve seen it countless times.

Is it really just me that thinks having oodles of young adults taking amphetamines daily is OK? I just can’t seem to wrap my head around it.
A google away, with the term being "probability cheatsheet". There are cheatsheets out there for many subjects.
And even that would give them a measure of the benefits. If it’s the same benefit that actual ADHD receives then it’s still a useful metric. If it’s less than the benefit when used for actual cases then, in aggregate, the benefits would be a low bar. Arguably that’s a better bias as it would make the benefits/costs decision more conservative. They’re taking the difference in measurements for each individual.

I was surprised the article doesn’t mention “sweat equity” or “sunk cost.” Labor has value, even when you’re just building IKEA furniture or hunting for antiques. It makes sense that people place a higher value on their own labor than that of others, because the cost is intuitive.
Socialism is used wrong also by self proclaimed socialists; modern day social democracies are not exactly pure socialists either.

Socialism can’t coexist with Communism its economic theory is not compatible with either the political or economic theories behind communism.
I actually worry about the "something must be done" crowd cajoling lawmakers into lazily shoehorning electric bikes into the "motorcycle" category and erasing much of their advantages to own as a bicycle.

>Try setting a calendar entry for a date on which you'll follow up if you haven't heard anything back

Thanks for the advice, but surprisingly I have actually tried just not having ADD. This simple advice doesn't work very well for me, which is why I'm attempting to pursue medication again. The calendar entry goes off, I try to contact the doctor, maybe they're not in today, it's half way through the work day, I go to set another, I spot an email while I'm doing it and start following up on that, and then 4 months later it never happened.

My point is: idiots with access to phones that do idiotic things should pay for the consequences of their acts -- regardless of how good or bad the police force is. In this case, an idiot caused the murder of an innocent man, and should pay for it, full stop. There's no ifs or buts.

Of course this doesn't precludes police from making honest mistakes - or also doing idiotic things - but hopefully will remove the incentives from idiots-with-phones and their 400 potentially-deadly pranks per year.

One thing does not exclude the other. But we can sure as hell eliminate the root cause by making an example of cases like this.

Sorry, no idea what this means. Took plenty of history and government in high school. Have a casual interest in the USSR and strong interest in general policy.
Have you seen this:

https://budnitzbicycles.com/bicycles/view/titanium-ebike

I think it’s the closest you’ll find to a bike the looks and operates almost identically to a traditional bike. No wires, no display, excellent weight, etc. Obviously the price is out of control, but still the right idea I think.
Your entire argument is just a thinly sourced (anti)appeal to authority argument. You can’t sum up a persons life experience from a short bio and their github history (most of mine is private for example)

If you don’t like specific ideas of his, attack them. But as a 30 year engineer whose managed teams as large as 40 people, while i don’t agree with everything he wrote, lots of it rings true to me.
This is a little outdated. Most banks finally got Zelle setup this year. It hasn't fully caught on but you can get free transfers between nearly all big banks and a lot of small banks simply by setting it up and knowing the persons email or phone number. I've been trying to get my friends to move off Venmo, but the option to do it is usually buried inside of the banking apps so it isn't as convenient.
Unfortunately, I am compelled to make sure people don't read too far into this: this is phenomenally far from the truth. I am sure some schools have stronger engineering schools than math departments, but to say this generalizes is honestly borderline absurd to anyone that has gone to a school with a good math department.
This is the consequence of the United States' governments and citizenry refusing to move on reform in a reasonable timeframe.

While citizens are fighting against the insane hordes for legalization on a state by state level, corporations are starting operations in states where it is already legal, because they have the capital to do so.

By the time weed is legal in all 50 states, the marketplace will be completely locked down by giant corporations.

What I'm saying is you people are fools. You lack foresight and you dig your own graves and now you're whining about it. Maybe if everyone would start using their critical thinking skills a bit more instead of crying about how I'm being hostile or rude or whatever you'd see I'm right and what you all needed is a kick in your collective asses.

I want whats best for everyone, but the people don't listen to me, and they treat me like the problem when the real problem is themselves. shrug

For those of you who aren't taking irrational personal offense at my words, heed this: All legalization MUST include provisions that allow citizens to grow their own pot. This is the only victory we'll have against the corporations. They're going to steal the marketplace, so be it, but if we can grow our own then it won't matter.

ACH works on a pull basis rather than a push basis. Instead of telling the bank "send $100 to account XXXXXXXXXX at bank YYYYYYYYY" you tell the bank "give me $100 from account XXXXXXXXXX at bank YYYYYYYYY". That makes it okay for paying a large business that is easy to track down if they take too much, but it makes it unsuitable for paying a normal person because they could just empty out your bank account and then disappear.

It's often a way that people group collections of related subprojects of an open source project, e.g. Babel is an org, with babel/babel being the primary repo: https://github.com/babel

People who make an org rather than just a project are probably more serious about it, which explains the higher activity rate, but it's still just "someone on the internet tried out an idea".
