a full suspension e-bike, 500+Wh battery, with a belt drive for $4,500 is honestly a really good deal. There is a shortage of options when it comes to full-suspension bikes that are good for commutes. Compare this to any e-bike with the Bosch e-bike system. The big risk here for consumers if whether they can match the service, support, and reliability that Bosch has. There appears to be a class-2 e-bike option which is something that significantly differentiates it from bikes with the Bosch system.

It's interesting because there's a significant chance one wastes more time tinkering around with custom scripts than saving in the long run. See https://xkcd.com/1205/

For example. The "saves 5 seconds task that I do once a month" from the blog post. Hopefully the author did not spend more than 5 minutes writing said script and maintaining it, or they're losing time in the long run.

About 75% of the time I look at the Gemini answer, it's wrong. Maybe 80%. Sometimes it's a little wrong, like giving the correct answer for another product/item, or the times that a business is open wrong. There's a local business I took my wife to, Gemini told her it's open monday to friday, but it's open tuesday to saturday, so we showed up on a monday to see them closed. But sometimes it's insanely wrong making up dozens of wrong "facts". My wife started looked more carefully now. My boss will even say "Gemini says X so it's probably Y" these days.

if you use x0vnc (useful if you use a linux machine both from the attached screen and from vnc, and in a bunch of other scenarios), copy and paste to and fro the vnc client is not implemented, quite frustrating. here's 2 scripts that does that for you, I now use this all day. https://github.com/francoisp/clipshare

I totally agree with this, I end up working on many systems, and very few of them have all my creature comforts. At the same time, really good tools can stick around and become impactful enough to ship by default, or to be easily apt-get-able. I don't think a personal collection of scripts is the way, but maybe a well maintained package.

Good point, I guess that's why I find this comments section boring and not representative of the HN I've known for 16 years: there's a sort of half-remembering it wasn't powerful enough to do something plainly and obviously useful yesterday.

Then, we ignore today, and launder that into a gish-gallop of free-association, torturing the meaning of words to shoehorn in the idea that all the science has it wrong and inter alia, the quantum computer uses quantum phenomena to computer so it might be a fake useless computer, like a wind tunnel. shrugs

It's a really unpleasant thing to read, reminds me of the local art school dropout hanging on my ear about crypto at the bar at 3 am in 2013.

I get that's all people have to reach for, but personally, I'd rather not inflict my free-association on the world when I'm aware I'm half-understanding, fixated on the past when discussing something current, and I can't explain the idea I have as something concrete and understandable even when I'm using technical terms.

> trash a.txt b.png moves `a.txt` and `b.png` to the trash. Supports macOS and Linux.

The way you’re doing it trashes files sequentially, meaning you hear the trashing sound once per file and ⌘Z in the Finder will only restore the last one. You can improve that (I did it for years) but consider just using the `trash` commands which ships with macOS. Doesn’t use the Finder, so no sound and no ⌘Z, but it’s fast, official, and still allows “Put Back”.

> jsonformat takes JSON at stdin and pretty-prints it to stdout.

Why prioritise node instead of jq? The latter is considerably less code and even comes preinstalled with macOS, now.

> uuid prints a v4 UUID. I use this about once a month.

Any reason to not simply use `uuidgen`, which ships with macOS and likely your Linux distro?

I was mostly talking about state actors buying quantum computers that are just built to run that particular algorithm and using it to snoop on poorer countries who cannot afford such tech. Plus all countries will have plenty of systems that have not been quantum proofed. The moment when it becomes affordable to a state actor until most state actors have access to such tech is likely to be a long time especially since no one will admit to possess such tech. And unlike nuclear weapons, it is much harder to prove whether or not someone has one

I've also wondered about a balloon launch. Strap the rocket to an enormous blimp, it handles the initial 1-2m/s acceleration, saving an enormous first volley of rocket fuel needed to break objects at rest out of their state of rest.

After the rocket is clear, activate compressors inside of the blimp and return it to base for re-use.

of course it is, how else are you going to create a drill string that needs to grow to 10000m+ long? drill pipe is flexible(ish, for varying definitions of "flexible") but not nearly enough to do a coil of it for that long. coil tubing is a thing but is much thinner and smaller diameter and isn't nearly as strong. it also can't rotate.

drill string comments aside, this appears to be a very standard deepwater offshore drill ship

Great! Another bunch of micromobility products that nobody asked for. And the price! I can buy 6 very decent Chinese ebikes of various formats for the $4500 this thing will cost. I'm sure it will be more advanced and nicely designed, but it's just way too expensive. Bicycles are a mass-market item. Price is the primary decider. If you want to be successful, you have to be cheaper than the competition. Who is this for?

The battery system here sounds so sweet. Swappable, with a respectable 0.5kWh and then an Extended Range 0.8kWh is excellent.

Usb-c chargeable at 240W is divinely sweet. Maybe maybe some day dual USB would be nice (for the ER especially) but this is quite respectable. And by not trying to super fast charge the battery will live longer anyhow.

Being removable is another nice win, if not uncommon. I don't know which other batteries provide USB power even without the bike, which again is such a great nice to have: take the bike to a park then bring with an charge some phones or what-not.

In the future I really hope we see some battery alliances, making some form factors, and centralizing on usb-c. As would be good common sense. The overlap between a bike battery and standalone Delta or Ecoflow battery power station is huge, and Rivian here seems a little further along than most at hybridizing & generalizing a battery system: obvious win to anyone paying attention!

The modularity could be a major win too. I'd love to see a an e-bike maker go down the Ford Bronco path & add a bunch of attachments points and replaceable/modular pieces to the design, and release all the specs for free use! Even if it only is Rivian and some partners doing this here, this is the way, it feels like:

> The top frame of the TM-B is modular by design, so the bike can be transformed without tools into a cargo hauler, kid carrier, or cruiser with a bench seat.

Cargo haulers easily climb to the 6000$ ranges. And the massive 180NM motor here will not bat an eye!

One thing I'd love to see: a stationary bike mode. Bring it inside for the winter & do spin class, charging up the battery. The full series hybrid, no mechanical linkage, doesnt deel super super practical to be honest but it's interesting!

A lot of nice basic things that make sense. Like no longer needing special cherging equipment for reasonably good capacity chwrging (albeit most usb-c chargers will only be doing 100w for a while now, but that seems fine).

Surely winning the AI race is finding secret techniques that allow development of superior models, with it not being apparent that anyone has anything special enough that he actually is winning?

I think there's some firms with special knowledge: Google, possibly OpenAI/Anthropic, possibly the Chinese firms, possibly Mistral too, but no one has enough unique stuff to really stand out.

The biggest things were those six months before people figured out how O1 worked and the short time before people figured out how Google and possibly OpenAI solved 5/6 of the 2025 IMO problems.

Getting control of immigration, which includes deporting them and massively overhauling the asylum system and seriously addressing and investigating the grooming gang scandal, which is probably the biggest scandal in recent history. I would actually now add a third thing which is to reign in the out of control police who are arresting people for causing offence. By the way these aren't even the biggest problems facing Britain, just serious ones which are recieving the most attention and for good reason, because they should be simple to fix and they are throwing away our sovreignty for terrible reasons.

I loathe Kramnik and I am saddened and shaken by Danya's death. (We both played at the Mechanics Institute Chess Club.)

I do know from previous discussions that some companies are in us-east-1 because of business partnerships with other inhabitants and if one moves out the costs and latency goes up. So they are all stuck in this boat together.

Still, it would make a bit of sense if you can find a place in your code where crossing a region hurts less, to move some of your services to a different region.

While your business partners will understand that you’re down while they’re down, will your customers? You called yesterday to say their order was ready, and now they can’t pick it up?

Putting the motor into the wheel makes for an excellent riding experience, I have a Bionx rear wheel (out of business) that is connected to the chain ring and pedals in the traditional way. The wheel detects torque from pedaling and applies it's own torque to drive the wheel. It can be used with and without power and feels almost seamless and is silent.

Unfortunately it seems to be difficult to engineer and build these wheel motors for reliability and longevity. They significanly increase the unsprung mass of the wheel which leads to increased wear on the hub components.

Hello! Novelty is incredible.

While economics is basically voodoo, it appears you've stumbled onto a fast track to derailing the country.

The federal reserve flipping $600 capital into $5400 of capital also creates $5400 of debt. Possibly more over time as interest weighs of the $5400. The way banks "flip" assets into higher amounts via fractional banking is by loaning it out. It doesn't just become 9x'd on their books magically. Someone has to take on the debt.

I'm not seeing how this is self-financing anything; it looks more like refinancing while causing gigantic inflation of the money supply by 9x. A $1 today is worth $0.10 after this. This is circular investment with leverage, backed by an increasingly unstable government.

Can you explain more on this actually works in practice? Where is any upside? Current debt goes away, but is replaced by 9x as much debt held by the federal reserve or swf?

I'm Indian -- I think a lot of this comes from the fact that the Brits left such a horrible legal system behind that it's hard to trust it to resolve disputes well. So people default to family/community trust relations.

I've been lucky to work in high-quality teams where nepotism hasn't been a concern, but I do understand where it's coming from (bad as it is).

> Laws need to be written well to achieve good outcomes.

This is a critical failure point which should get more attention. Laws (and regulations) are like computer code in some key ways. Early computer code was written assuming it would be run by experts in trusted, benign environments that were relatively fixed in size and complexity. Our legislative law-making structures were created with similar assumptions. As the world changed, code changed but law-making structures didn't.

At a minimum, while being drafted laws should be subject to independent red-teaming and penetration testing to A) Assess their ability to actually accomplish their stated intent over time in the real world, and B) Surface likely unintended perverse consequences. Of course, that still wouldn't solve the issue of intentional weakening of laws with vague terminology, incomplete scoping, inserting loopholes, exceptions, etc by special-interest-driven legislators.

Sadly, these days I think intentional nerfing of laws during drafting is the biggest cause of 'bad laws'. But at least the red-teaming concept might prevent some unintended bugs on top of lobbyist-driven nerfing.

And how do they manage the twist of a 7 mile drill. The torsional strain energy must be enormous; you can't just let it go. You would need to unwind that energy in a managed way. I suppose this is not a new situation for any oil drilling, even just a few hundred feet. This is one of those things a layperson thinks about in the first minute, and has been obviously been thought of and dealt with in a simple manner by experts.

It's all a challenge whether you have fine-grained permissions or coarse-grained permissions.

With coarse-grained permissions you end up needing proxies, which is nice because you can do whatever you want in terms of business logic, but also very much not nice because you have to write the proxies and the client code to talk to them, and then you have to keep maintaining and extending them.

Either way you have to do audits and static analysis looking for escalation vectors, and that's strictly harder -but not insurmountable- with fine-grained permissions.

So I think fine-grained permissions win.

I've implemented (and I'm trying to get approval to publish a paper on) a cross between RBAC-style and SMACK-style labeled security (where the labels are literal human-readable strings, not MLS-style bitmaps + levels) for application-level authorization, but it's very fast and should work in-kernel too if anyone wanted to make it work there. This system lets you have authorization as fine- or coarse-grained as you want by using many distinct labels (fine-grained) or few labels (coarse-grained) to label the application (or kernel) objects with.

This is happening everywhere. In every industry.

Our economy is being propped up by this. From manufacturing to software engineering, this is how the US economy is continuing to "flourish" from a macroeconomic perspective. Margin is being preserved by reducing liabilities and relying on a combination of increased workload and automation that is "good enough" to get to the next step—but assumes there is a next step and we can get there. Sustainable over the short term. Winning strategy if AGI can be achieved. Catastrophic failure if it turns out the technology has plateaued.

Maximum leverage. This is the American way, honestly. We are all kind of screwed if AI doesn't pan out.

does that actually matter much on anything except dirt-bike tracks, or trying to go 40mph on a horrifically bumpy track? minus some comfort advantage, of course.

like technically, sure, it's obviously true. but for performance it only really matters when you would get air time with higher mass, and the lower mass stays in contact more. commuter e-biking generally doesn't get anywhere near those speeds or bump-sizes. (trail biking: sure! I 100% believe it's a sizable consideration there)
by pchew | 2025-10-22 19:09:58+00:00
There's literally thousands of e-bikes with touch screens and it would be unsafe for a bike of this weight to have anything other than hydraulic disc brakes, which are the standard for just about anything that isn't a road bike these days. Locator also pretty common even on $1,000 ebikes.

But yes, other stuff seems to be features for the sake of features.

808Wh battery and 100 miles of range. These two numbers track with each other and are roughly believable.

OTOH, with a battery this big, a generator powered by the pedals, and regen braking this thing has to be heavy. I'd expect it to weigh at least 80 lbs. More likely 100. The fact that their "specs" say nothing about weight suggests they're embarrassed about the weight.

How else should we view them? Walks like a duck, quacks like a duck, probably a duck.

Because they were placed in a position of trust and failed. Typically, the failure stems from a lack of willingness to expend the resources necessary to prevent the failure.

It'd be one thing if these were isolated incidents, but they're not.

Furthermore, the methods you mention simply aren't effective. Our economy is now so consolidated that many markets only have a handful of participants offering goods or services, and these players often all have data and computer security issues. As for divestiture, most people don't own shares, and those who do typically don't know they own shares of a specific company. Most shareholders in the US are retirement or pension funds, and they are run by people who would rather make it impossible for the average person to bring real consequences to their holdings for data breaches, than cause the company to spend money on fixing the issues that allow for the breaches to begin with. After all, it's "cheaper".

Dirt bikes and many motorcycles also have chains, this allows you to change gears to adjust torque (alternatives include shaft and belt drives).

E-bikes can have the motors on the wheel (hub-drive) or on the pedal (mid-drive). This choice is largely related to how much you want your e-bike to really be a scooter or really be providing pedal assist. As a consequence hub-drive e-bikes typically have a throttle while mid-drive do not.

A good mid-drive e-bike really makes it feel like you are a super human cyclist rather than riding a scooter. It leads to a much smoother riding experience if your aim is to still be essentially bicycling but you'd like to get moving faster and not break a sweet even on the most extreme hills.

I remember System 7 being full of race conditions: MacOS was originally designed to get events from the keyboard and mouse and disc and when they started coming from the internet for web browsers it broke down.

System 8 dealt with the problem by putting in lots of locks which slowed everything down and it made it unresponsive, at least if you didn't have the latest machine.

Classic MacOS was doomed at this point because it was designed for 1984, not for 1988 and Apple had to hustle to build an all-new modern OS.

Absolutely.

This is also a typical approach from the chefs I know: they don't care about precision in most recipes (eg. dishes like soups, or pasta, or salads...), but then sometimes there are dishes where precision is absolutely crucial, and baking is one place where precision is really important.

With sourdough, if you don't measure, you may still get good results, but you will have to babysit the dough and try to figure out when it's ready by checking frequently. Some people can afford it time-wise, and to some this would be prohibitively inconvenient.

Resolution is extremely important for VR and trying to display screens and text. The best screen you can possibly reproduce is the same resolution as the screens in the eyes and takes up the whole FOV so for anything further back than that the headset can only approximate what the screen would look like (down to the point of diminishing returns where the pixels are smaller than your eye can resolve).

Yep.

And when that's a problem, it's fine to just cut and insulate 3.3v wire that feeds the power supply's SATA connectors.

After this modification, the machine thus becomes compatible with all SATA hard drives, whether old or new or shucked or whatever.

(Not much (if anything) in SATA land ever used 3.3v, and it's completely likely that nothing ever will. AFAICT, that voltage was deprecated with the release of revision 3.3 of the SATA specifications, from nearly a decade ago in February of '16.)

"It's complicated" I guess.

https://fr.wikipedia.org/wiki/Le_Monde_diplomatique offers a few first insights. Note how the page quickly emphasizes the redaction's independence.

Yet, it might be reasonably true: as stated in the Wikipedia page, Le Monde Diplomatique is read mostly by educated people, who probably are 1/ less susceptible to/more aware of coarse manipulation 2/ much less numerous.

That's to say, influencing (too much) the redaction might have too low of a costs/benefits ratio.

Personal anecdote: I've read it a few times about a decade ago. At that time, I perceived some of the articles to be more emotionally grounded than rationally, and the prose to be at time needlessly heavy, "sophisticated".

Those are the main reasons why I didn't kept reading it more often.
