I'm surprised the author spent so much money building on top of a base bike of such low quality. That department store bike is what bike snobs would call a "bicycle-shaped object". You certainly shouldn't not be cheaping out on the actual bicycle for an e-bike, as you're putting the bike (and particularly the brakes) through forces they were not properly designed for. The author even admits such:

> The brakes are often too soft to handle continuous elevated speed. What ends up happening is that I spend more money overtime to upgrade the bike to my desired state. So far I spent about $1500, including parts and tools, this is accounting for a fairly cheap used bike on craigslist ($200). Had I bought a new bike, I would have had to spend probably close to $1900. To make it exactly the way I want it, I estimate that I have to spend an additional $800 to get install IGH, bigger brakes, and more efficient tires with less rolling resistance.

Frankly, the author's setup just sounds dangerous. The several-$K all-in-one bicycles that they refused to get on grounds of cost are expensive because they are actually built to handle the rigors of e-bike usage, and have incredibly useful features like hydraulic disc brakes. The brakes on that department store bike are "disc" brakes, but they're certainly not hydraulic, or even good, at that price point.
What you want then is to follow the work of Slavoj Zizek who also wants to toss all failed political ideology like 20th century communism as it consistently led to authoritarianism. He is often pushing for a new political theory age. One interesting theory was Murray Bookchin's 'Libertarian Municipalism' as it is designed to operate within a state as a horizontal not vertical power and gradually reduce the centralized control over populations https://www.jacobinmag.com/2016/07/murray-bookchin-ecology-k...
Since we're mostly debating the police action here, there's a short video available now of the fatal moment:

Another class of scam that I've heard of frequently over the past few years is a job offer. Such offers typically offer more $ than Google/Facebook would offer but people still fall for those. They typically ask for money in order to process visa and other formalities.

I've read about motorized doping in bike races, with motors hidden inside the gearing, I wonder whether anyone's thought about this sort of thing for consumer bikes, and what sort of benefit you could get for, say, 1kg or half a kg of extra weight. E-bikes at the moment seem to have reconciled themselves to being twice the weight of ordinary bikes.
> "...but the US does have a problem of over-testing, over-diagnosis, and over-treating illness. Not just mental ill health, but everything."

I'd argue this is a symptom. The root disease is the profits to be made from various testing positive.

I'd add that it's aided by the fact that most people believe the doc can (and should) script you a pill for just about everything. Prevention? That's not going to happen. The patients know it, the doctors know it, and the insurance company pays for it.

Do I think everyone should have access to healthcare? Yes. But everyone should also be mindful if personal health. That isn't the case. And since soneone else is always paying for it, and the med pro are too broken to push back, we get what we have.

Illness as a badget of honor.
One of the problems with external drivechains on bicycles is that they're exposed to all sorts of harsh elements like rain, mud, and road salt in winter. Even ignoring that, unless you have good parts and you're really on top of your maintenance and constant adjustment, it's pretty easy to have the chain slip or not engage properly on the chainring/cogset when shifting.
Considering the alternative is employing a person who has to go around and read every meter versus the very low cost of a GSM radio I think it very clearly makes sense cost wise.

> And I'm mad that police are shooting people, innocent or not, based on vague gestures that sorta, maybe, if you look at it from the right angle, looks a little threatening.

I can understand that, but I recommend caution when it comes to judgement. Combat is every bit as technical as system architecture, and I think it requires related experience to judge fairly. Movies prepare you to critique a fighter about as well as they prepare you to critique a system security posture. Which is to say, not at all.

The best way to understand why police react the way they do is get a little experience with the real thing: watch footage of actual confrontations. Here are some examples:

https://youtu.be/uyEE_IpjstA
https://youtu.be/2mnTE85LYFU
https://youtu.be/p6mds5tDqDw

Combat is fast. When someone makes a sudden move, you have to react immediately or you will lose.

I'm mad that this went down the way it did, too, but from the description, it is very understandable. It is tragic that people with no combat background just don't understand what looks threatening and why. You'd no doubt consider it foolhardy to point an airsoft pistol at a policeman, but probably don't understand that a movement that could be a fast concealed weapon draw is just as threatening.

I do a little martial arts, and we train that if someone is hiding their hand, assume it contains a knife or gun. If you have your hand behind you or in your pocket and move it fast, I have to react as if it's an attack, as that's the only way to avoid it. It takes too long to identify a weapon.

Look at some videos of knife attacks, for example:

https://youtu.be/dqnwsljTVt8
https://youtu.be/ts2LCbDQkeg

They are fast and sudden. The only way you can hope to defend them is to assume a hand you don't see is about to hit you with a knife.

Which is why police are jumpy. This is the environment they work in and what they train for. If your day to day life involves no violence, your ideas about what's reasonable in that context don't come from applicable experience.

> I said yesterday that, as a hearing-impaired person, if I'm ever in a position where police are pointing guns at me and shouting instructions, I expect I will be shot. I'm honestly not sure what I can do to prevent that.

Move slowly. Keep your hands very visible and very obviously empty. Even if you can't hear the officer's commands, moving slowly and keeping your hands visible will keep you from appearing suddenly threatening, which should let you get the situation sorted out.

I can't help you if you run into a policeman who is a bully, but most of these tragedies are misunderstandings between good people. The very best way to avoid that is to do everything slowly and deliberately. Don't panic. Just move slowly and carefully. Pretend the cop is a dinosaur or something and sudden movement will provoke him.

No, not steam, just hot water. Yes, mostly from heat & power plants, but sometimes from gas-powered local boiler plants. They are metered on per-building basis, but there's technical possibility to install individual meter and pay only for actual consumption.

My work laptop - admittedly not a high-end machine - takes about two minutes from power-on to login-prompt. I've seen Windows machines - without SSDs - that had tons and tons and tons of software installed on them, that took 10 to 15 minutes from power-on to login.

Compared to that, <30 seconds is very fast. SSDs have been a real game-changer, though. My home desktop takes less than 10 seconds from boot manager to display manager. I used to be very patient, now I kind of regret all the time I spent waiting for some computer to boot. ;-)

The C64 boots off ROM, IIRC? So that is kind of cheating. ;-) But yes, I had a C64, too, the delay between switching it on and the machine being usable was too low to notice.

I bought a Pedego electric bike this summer to replace a car.

I work from home, and there are many stores, restaurants, my Dr, etc. within a 30min e-bike ride, so we tried this experiment.

It's working out rather well in Myrtle Beach, SC.

My bike did cost me over $3k, however I too went through the process of evaluating what it would cost to build my own. aconsidering my weight (300lbs) The Pedego Stretch was one of the few bikes designed to handle that weight, and has the largest battery in the Pedego lineup. I've been happy with my purchase (including 0% APR financing for 1 year - making it a cheaper monthly payment than the lease I traded in - and that cost goes to $0 this coming summer).

It definitely opened up possibilities beyond a standard bike, and removed the feeling of being 'trapped' while working from home with no car while my wife has it at work.

You’re ignoring the marginal cost of requiring meter reads with dumb meters, though, let alone any other benefits that the meter might offer.

I agree that the WAN tech is perhaps more suitable in theory, but that ignores the fact that there is already a ubiquitous GSM network in place.

I was referring to ACH, not credit cards.

Also, something you said in a related comment:

My experience is that every US bank has an "external account" transfer feature (for use with your other accounts) that can initiate ACH credits or debits, as well as a "Bill Pay" that will do ACH credits to any routing/account number. But (as I alluded to) banks limit the dollar amount of transactions initiated through them, as they are responsible for cleaning up any mess due to "fraud".

Can Cataracts Be Reversed Without Surgery? – Is It Possible?
It's interesting how the focus is on almonds, grapes, tangerines, lemon etc.

Much scarier than the polluted almond, is the amount of these pollutants that get into the grass, grains and other things the livestock industry in California uses. A big chunk of water is used by the livestock industry (what to feed the poor cow if not the polluted cheap water, who cares about the welfare of a cow), not the lemon guys.

Bioaccumulation of some of these compounds is a much larger risk than eating a fist of almonds. There could be 100 times more of the pollutants in a fist of beef, given that the cow chews through literal tons of grass and grains before slaughter.

Yet one should worry about that tiny drop of lemon juice on your steak.

You might be looking at ADHD too much through the lens of buying some Adderall before a uni exam so that you can nail it.

ADHD interferes with everything from social relationships to doing anything that you want to do. We have to be productive insofar as to pay for food and shelter, but you're addressing a very narrow aspect of what ADHD medication treats. For some people, it's the ability to socialize, finish a joke, and achieve their life ambitions.

You have it backwards. SWAT police move aggressively, at great personal risk, in order to save civilian lives. The idea is that there is a hostage situation and hostages are being actively killed.
This. For the $1500 the author spent, he could have bought a decent bike instead of strapping a motor on a $200 piece of cast-iron junk.

Plus, a 1000-watt motor is ridiculous: that's the kind of power generated by a pro sprinter, and over twice what a pro climber generates on average. A 100-watt boost would be enough of an advantage to make most hills easy, and would probably weigh and cost far less.
