> Then there is likely to be a pretty large difference in speed between e-bikes and ordinary ones, so that's dangerous too.

I disagree with that part. Most e-bikes are speed limited to 20mph, a speed plenty of unassisted bikes can achieve if the rider feels like it, and plenty do. Bike lanes already have a variation in speed.
I have tried ObservableHQ but I am not sure it helps me understand D3 as much as it does help me use it like a Jupyter notebook.

And unlike Jupyter, ObservableHQ notebook does a lot of heavy lifting when it comes to creating charts for the web which outside that makes it really difficult to adapt to.

I guess I will have to follow the monkey rule until I really understand it well and need to learn desperately.
It is amazing much room there is to re-optimize cities around smaller electric vehicle transportation when you think on a slightly longer timescale.
Ephemeral platforms seem like they'd be less attractive targets to the bot shill farms than a place where you might be able to stick a top comment in a thread and get all the eyeballs on it forever.

While I absolutely condemn riding ebikes on sidewalks... I suspect that's still safer for pedestrians than cars. Especially cars driven by the kind of asshole that would ride an ebike on a sidewalk.
I got a boosted board years ago, before they went out of business, and I've been a huge fan ever since. It's definitely harder and more dangerous than a bike or scooter, but it's super fun and ultra compact for taking with you into destinations or onto transit vehicles.

Too bad. Someone comfortable tinkering could replace the battery and get it back on the road.
I bought an REI brand one, just for the peace of mind of knowing REI will work on it and support it. And the guaranteed return policy. YMMV, there are other good options. But the number of options is a bit overwhelming.
If it led to replacing bikes with ebikes, then you’d be correct… but not if it replaces cars with ebikes (which is what it actually does, as the article confirms).

Your biggest mistake is to think that the Russians don’t want to appear as monsters.

They are more than happy to, so much so that when they commit war crimes like blowing up the dam.

They cheer it on and want their military to blow up even more dams.

Just like when they downed MH17 Russians were cheering on this destruction until they learnt about the disgust from the international community.

Then the switch flipped and people like yourself went into overdrive to try and deny more Russian war crimes.
Where do you park a $3k+ ebike in a city? Most places I've lived, a $3k bike parked on the street wouldn't last more than a couple of hours.
Sure, but those tend to be much more expensive, so depending on the actual cost of electricity in your area, it may take a long time for you to break even.

However, if you want to have a really small appliance-like pc, then yeah, the NUC-sized ones are much better.

> Let’s be clear: if an environment can’t be created/deleted with a single command, and normal changes to its configuration (ex: size) can’t be applied in a simple way, you are not doing Devops. You are a sysadmin and you are living before 2012. No amount of money paid to the yellow cloud provider will change that.

We are living in a world where operations and system architecture is more complicated than ever. Is it hidden behind more layers to where more people can use it in a self service fashion? Yes, but that not does not mean it's simple.

The goal of making an entire environment that can be created and deleted in one command is often a naïve goal. If there's any complexity in what you're deploying you'll quickly find that you'll have gaps in your automation, there will be things that the cloud provider hasn't surfaced, Terraform cloud modules will be out of date, things that need to be configured with a certain level of layering or ordering outside of scope. You can get close, but it's often wasted cycles met with frustration.

If you're spinning up something simple sure, but the idea that if you can't create a potentially complex environment with one command "in a simple way" just goes to show me that the author hasn't dealt with a complex enough environment.

When I first started my career I was working with a ton of systems administrators, a lot of IT workers as you'd say. The issue is a lot of the work becomes remedial because standards are not in place. Frameworks aren't consistent and you end up with sprawl that grinds away any resemblance of structure. Personally devops/SRE, or whatever you'd like to call it has changed that outlook.

Instead of remedial work on a linux VM we have tooling and a higher form of standards so you don't have some grey beard reinventing the wheel creating a silo on a farm of VMs that no one wants to touch.. it has made things better, not perfect though.

Ultimately the culture and tooling doesn't remove the human aspect, I see the same thing in other fields like data engineering, or SWE where people will go above and beyond to create something already figured out, reinventing the wheel so to speak. Ultimately creating their own job security forcefield or works of art that no one in the company is willing to touch that provides a fraction of usability that something out of the box would provide and a lot of headaches instead.

Over the years I've learned that consistent solutions that are clear cut and adhere to some sort of shared standard are a win. I have a feeling that many think that's boring and would rather create their own path. I think that's where things get messy for the average tech worker.

I'm at about 90% eBike school dropoffs and pickups. Love it. Especially as I work from home. I started by doing them all at "Turbo" assist. Now down to "Tour" for the most part as my fitness improved. Love the incidental exercise, fresh air, so much easier to stop off somewhere and dropoffs are just nicer. I'm lucky that I live a few blocks from an eBike store and I could afford the impulse buy one day. Very little thought went into it.

I am going to half answer as a guy with a law license in California. My guess is Reddit thinks that as long as your username is deleted they’re OK. This is problematic if you have posts that identify you. I’m also going to guess that that distinction hasn’t been tested in court yet, I could be wrong. I’m also going to guess that “malicious compliance” is sufficient.

California has pretty activist courts, so they might have a case. But you’re looking not so much for a business lawyer as someone who specifically focuses on this law.

Many (most?) things aren’t as black and white as most people think in the law.
Gen X matters though as they’re almost as big and are split on who won the housing/education lottery and who didn’t. Its oldest members are 58.
You’re describing removing the rear glass (and it takes 30mins, tops, I’ve done it). Something that’s not covered by the EU legislation I might add.

It literally says the following about removing the battery (emphasis mine)

> Unfasten the battery connector cover screws

and…

> remove the single 1.0 mm-long screw securing the charging coil connector cover

After that it’s just two easy to remove adhesive pull tabs to get the battery out (which would pass the test for user replaceable in the EU law).

Complain about how hard it is to get the glass off, fine, but that’s got zilch to do with the EU law

Grayscale AA is still common on Retina screens, but subpixel AA is rare. Mostly because subpixel AA is difficult to do compositing with transparency with, but also because it's less necessary on Retina screens. The tradeoffs are just to the point that it's not considered worth it.
> pedestrians walking into traffic while staring in their phones, jaywalking in other words

This is... not the definition of jaywalking. It is legal to use one's phone while crossing the street.

Aside - history of the term "jaywalking," from Wikipedia: "The word was promoted by pro-automobile interests in the 1920s, according to historian and alternative transportation advocate Peter D. Norton. Today, in the US, the word is often used synonymously with its current legal definition, crossing the street illegally."
I'm fortunate to live in a century home neighborhood (Waterloo region, Canada) where the elementary school has a tiny parking lot that is strictly for staff only. A few parents moan about having to park on nearby side streets and walk their kids in, but the net result is overwhelmingly a huge positive— almost everyone walks or bikes to school, and is safer doing so for the fact that there isn't a giant traffic jam in front of it.

I often feel that it's a fragile equilibrium though— it wouldn't take much to get the sports field turned into a big parking lot and have everyone immediately defect in the face of it not "feeling safe" any more.
A lot of places just wont let you use a voip number, but if you port in a number to a voip service this often works and lets you maintain the number for pretty cheap. It is a big hassle, though, if you are trying to cycle numbers regularly.

For grocery stores and other things that aren't going to try to use it for 2fa I just use arbitrary numbers of other local businesses. Sometimes it's even already registered!
> A single regression within a monolithic code base can bring the whole system (in this case, all of Uber) down.

Serious question: why though? I can't think of a backend system where a single regression could bring the whole thing down. If something blows it up, it rarely takes the whole application down. What's this scenario exactly? Maybe I'm only thinking of certain types of applications, but a single failure somewhere needn't bring the whole thing down.

> Poor separation of concerns. It was difficult to maintain good separations of concerns with a huge code base. In an exponential growth environment, expediency sometimes led to poor boundaries between logic and components.

I kind of get this...The idea is that if the other area of code simply isn't accessible to you, you're forced to keep the concerns separate? Seems like this could be dealt with by applying more discipline and just making sure to design things to be more modular and.. separate. This is the hallmark of any good code base. Do we need an entirely different architecture, with all the pitfalls that microservices entail, because we can't seem to keep things clean and separate?

I really am asking these questions in good faith. I won't hide the fact that I'm skeptical of the microservices fashion (and I know that Uber is at least trying to be more thoughtful here), but I am totally open to being convinced otherwise. I'm at this very moment gearing up to begin a new large project and am wondering what design makes the most sense and whether there's a place for separate services so I'm curious to hear what people think. The one area I'm thinking about specifically is the fact that difference parts of a monolith might have different scaling requirements and if you have a single application then everything has to scale out or in as a unit. But it seems like this doesn't require a separate code base necessarily...just the ability to run different parts of a single code base as its own applications or unit of deployment, no?

It’s weird to be how much some people hate market makers and traders who apply arbitrage strategies. I don’t think there would be as much hatred for HFTs if people understood what it is they do. They make markets on securities and arbitrage things. For example, creating units of SPY when it gets too far above NAV to bring the NAV back in line with the index. I’m sure there are more strategies I’m unaware of, but it’s not like Millionaire HFT man is picking the pockets of retail traders, there’s real money to be made elsewhere.

"love" it that you got downvoted for expressing common sense based in your expirience

In Israel ebikes/escooters became popular 15 years ago if not more. They are universally hated by non riders, because

- riders tend not to obey any rules

- there is a bunch of deaths every year because e-whatever run into pedestrians on high speeds

- it's very fun to ride car on road and have somebody on e-whatever play chicken with you. especially during night. (once, one of those riders chased me to my home and demanded "compensation" for something)

- a whole bunch of fires due to exploding batteries (there is now Israeli startup that installs fire-proof charging stations/enclosures)

- no enforcement as policy too busy to deal with other stuff

So yes, for those who use it, it's probably comfortable and fun. Adds another drop into solving transportation/environmental problems. But at absence of proper legalization and enforcement it's not fun not be around them
If you really start looking for companies that pledge to support battery replacements for 5 or 10 years after initial sale… well, I haven’t found any.

Meanwhile, my 20 year old manual bike is still good as new.

Or go looking for a company that will take an old e-bike and recycle it upon purchase of a new bike, I’m not finding that either.

So it’s easy to be flippant, but if you have concrete links to either of the above, that would be far more useful.

So what if a company isn’t profitable? Do you think that companies don’t need to pay for electricity or rent just because they’re not profitable?

As for your “personal/private services”, aren’t those covered for free under the RHEL individual developer subscription?
I had an ebike until it got stolen, I got another one, and the 2nd one got thrown out by my property manager, and I had to keep getting new bikes every now and then as my property manager would throw them out (yeah, they do that -- but the savings I get on my rent-controlled apartment with this shitty management compared to other apartments in the area is totally enough to buy a new ebike every 2-3 months -- hey welcome to America).

Anyway, as soon as I got an electric car I started using the ebike less and less. I was finding that it occupied an awkward middle ground between convenience and exercise. I now just use my car or my non-electric bike. The problem with ebikes is that when they run out of battery it feels like hauling rocks to pedal them. When you run out of "battery" on a non-electric bike all you need is a bowl of carbs and you're good to go for another 25-50 km. And carbs are much easier to find in the middle of nowhere than publicly-accessible electric outlets.
Exactly - this tactic converts busses from "shitty cars that stop all the time" to "faster, huge cars with a built-in chauffeur."

The quotation marks denote a very specific form of usage, one that generally implies a disregard/disrespect for those who use the word legitimately.

Using the word isn't the issue, it's How you use it.

Like using the word Jew. It's fine if you're saying "I'm a Jew" but not fine if you say "Get a load of that Jew over there".

Is that clear enough?
If there is ever a national subsidy for e-bikes (I’m in favor of it), it would be a lost opportunity not to use it to create a battery standard to reduce e-waste.
Cars very much took over streets, and not that long ago, so it's a fairer question than the current situation makes it feel like. My answer is no, they belong on roads. Streets are for people doing things, roads are for people going longer distances. We don't have a birthright to drive directly into a busy city and park next to the store we want, those streets should be for the people actually using the city areas. This is up to the cities to decide and implement, but any city area that prioritizes peds and other light transport gets a vote in my book.

I intentionally say city area not city, so it's understood I mean certain districts like downtowns and CBDs. Suburbia is what it is, you need a car there at this stage.

> Thank you for the explanation. Let me see if I understood. The basic draw is that it offers a programming language-agnostic specification for dependency management, replacing language-specific specifications like requirements.txt

Yes, actually I got interested in Nix because with requirements.txt I could only define python dependencies, and I had no control over for example installing postgresql C library that psycopg2 depends on.

> Then you pair it with a containerization technology like Docker or Podman

You don't have to, but you can, given that in most places containers are being used a lot of people use nix that way.

> And if you use NixOS, you can skip the last part?

Yes, although keep in mind that for example the requirement is to use Kubernetes then you would have to use Kubernetes. But if you need to create for example an EC2 instance. You can use Ubuntu + ansible or you could use NixOS.

Honestly I don't have much experience with NixOS as at my workplace we are mandated to use specific distro for everything.

Edit: I forgot to add additional benefits with using NixOS compared to Ubuntu + ansible for example. All updates are atomic. You either end up with the new configuration or the old configuration, there's no in-between as it would happen with ansible. Second big benefit is easy way to rollback.

It's also time to regulate ebikes to have standard and open interfaces to batteries and motors (you are welcome to have multiple standards and even create new ones if technology evolves). They are ridiculously expensive to replace for what they are - and how long they last, at least shimano motors.

The low-power AMD based systems everyone recommended a couple years ago were indeed great, until the ebay resellers realized what was going on and started slapping "opnsense pfsense AES-NI" etc on their listings and doubled their prices. The systems went from selling at $40-50 to over $100.

Also, the AMD processor in those systems is getting extremely long in the tooth.

Honestly the fact that they all become trash is why scooters annoy me. Like sure fine on a long enough time scale pretty much everything becomes trash but man they are not built to last.
Not in an urban area. E-bikes fly through sidewalks, bike lanes, crosswalks in NYC. Threatening pets and people at all times. Bikes were already bad, now it’s just more and faster.
You do realize that not just cars used roads?

Goods, groceries, e-bikes don’t magically transport to their final destinations.

Edit: there is this Captain Planet like view of cars as though most drivers are evil polluters. We are just trying to get on with our lives and aren’t privileged as folks who can afford to live car free.
This is not how it works, there is no sliding window, the model has no restrictions on the W and H dimensions, only on the C dim, so the UNet can actually be used directly on images with different aspect ratio and resolution; the attention layers pay attention to the entire image.
