This is the result this idea deserved.

Here’s a better idea: finance individual scooter purchases/leases as a business. Manufacturing will match actual not falsely inflated demand, and people will take better care, not just leave their scooter lying about on sidewalks and crosswalks.
Always a pleasure to see scummy monopolists lose billions and fail to achieve their monopoly.
Lyft/Divvy does this in Chicago. If you lock the scooter at a docking station, there’s no additional charge, but if you leave it somewhere else, there’s a small fine of $1

Those are probably homeless guys who have hotwired scooters.
I’d be curious of any research but my anecdotal knowledge of their use is not for planned trips but ad-hoc. I’m here and I could walk to X but I’ll pay 5 bucks to get there in 5 minutes instead of 30 or whatever. I don’t think most folks are using them for their daily commute- certainly that market will quickly do the math and get their own.
I believe this as well. And I happen to know of one of the largest rail systems in North America changes its topology weekly. I'm not sure "throughput over latency" is as much of a mindset as those here who say it is.
The value isn’t the cost saving compared to buying your own - it’s the convenience of being to pick one up anywhere and drop it off anywhere.

If you think you can carry an electric scooter with you around all day… good luck! I struggle to get one up a set of stairs.

That’s not to say that the price isn't wrong, but if the cost was equal between having my own scooter and having access to a rental pool, I would choose the flexibility of the rental pool every time. Having said that, I do think you have overstated the typical costs slightly too with a 15 minute ride costing c$3.
If the device were large enough that it was a hassle, maybe you'd have a point. But I've used these scooters. They're rather small.

They also beep at you if you're in the wrong part of the street, and they shut down seemingly randomly with crappy GPS sensors trying to keep you in certain lanes. If I had my own, none of that crap would happen.
You have describen practicing carpentry, not practicing math.

With the Bird scooter you're paying for the convenience of "free" parking (obviously the public pay in terms of sidewalk space etc., but to the rider, it's included), with no risk of a loss (to you) due to theft.

Yes, you can buy a scooter and the raw numbers make sense. But carrying a scooter up and down stairs, through elevators, and so on is a pain in the ass and, you need a place to store it at each destination.

The value in a Bird scooter isn't in the use of the scooter, it's in the non-use of the scooter. Jump on, leave it, jump off.
The RPi that runs basically all my outward-facing Internet services. Well, there's two RPis because I've been slow to move some of the more painful services across, but still all off-grid for ~2W total.

And it's also neat that my new MacBook Air will just about run with the screen off at ~2W also, which is also astonishing considering how it has come down over time for the MBAs, and yet is a full-on multi-core, multi-GByte system with 1TB of storage...

Propping up dictators and repressive authoritarian governments in exchange for resources? Sounds like something the "International Community" has done for over a century and continues to do.
> Why would the Chrome team build such a complex thing if v8 isolates passed rigorous security standards/bar etc?

This question assumes that there exists some threshold of "rigorous security standards" which clearly separates "secure" from "insecure". There's no such threshold. We know that risks always exist. No one can precisely quantify those risks. We can only sort of abstractly debate about which risks might be large, and take precautions by addressing those risks with defense-in-depth measures. Each such measure must, of course, be weighed against the costs -- both development costs and runtime costs.

Chrome made the decision that strict site isolation was a worthwhile trade-off to reduce risks. I generally agree with this decision. In Chrome's case, the overhead of extra processes turned out to be acceptable, and I think the risk reduction was meaningful.

In Cloudflare Workers' case, the cost of isolating every Worker in its own process would be much higher. We actually have the ability to do such isolation, and we selectively apply it in cases where we have other signals to suggest that risk may be elevated (such as when the Worker's performance characteristics suggest it may be engaging in a Spectre attack). But because Workers are designed to handle fine-grained events and often run for less than a millisecond at a time, the overhead of this isolation is much higher than in Chrome's case. The exact overhead depends on what the Worker is doing, but 5x-10x is typical (both for CPU and memory). Given this, implementing strict process isolation would not be a good trade-off for us.

Some people respond to this with "You can't sacrifice security for performance!!!", but this is naive. Again, all of the big cloud providers are trading off a whole lot of security risk for performance when they choose to run untrusted native code. In the real world we always make trade-offs.

Meanwhile, though, there are lots of other types of defense in depth that we can implement in Workers that isn't so easy to do in browsers. Dynamic process isolation is one example. Another is that we can automatically roll out V8 patches to production much faster than Chrome can. See the blog post I linked for some more examples.
While I agree that this logic applies to the first, and maybe (though this is arguable) the second, none of the later startups in the same space were plausible "home runs". If that model was going to work, it would work for the first or second company in that space (unless they were somehow pathologically mismanaged). An also-ran in the same space is not only less likely to succeed, but if they succeed it will be because that space will be one where there are many long-term competitors...which will mean they have no "moat", and cannot be the "home run" that the original investor was looking for.

So, in this case, you could excuse the investors in Bird and maybe Lime, but it seemed that there were a lot more companies than that.

You are absolutely right, thanks. It is better to compare to myself in the past.

I just forwarded your suggestion to him.
It isn’t an argument that we should believe in any particular religion. So, even if it works, yes it works just as well for Norse paganism as for anything else.

But still, an argument that “some religion is probably true” would have value even if it can’t tell us which religion is true
> Scooters are light enough that someone can just buy one and carry it around with them all day

The lightest of the e scooters come in around 30lbs. They’re not exactly small either. Certainly not easier to drag around than a bike, as you mentioned.
Perhaps already bicycles (widely owned) and other similar options to fill this need?
Yeah I also live downtown. The scooters and bikes here seen to be always be used, either by people who just want to get from A to B or groups of people just enjoying their time downtown.

The scooter companies tend to be smart too and relocate a bunch for any events. I'll frequently see dozens of scooters and bikes lined up and organized outside of the arena before whatever event gets out.
We've added it now.
It does make me feel a little relieved that I finshed education just before schools started computerising everything and social media took off. Had I been only 5 years later, the video of the fight I got into aged 12 would have been on youtube, school monitored laptops would have left me with little freedom to meet some people who are now my best friends (because talking to strangers online on a video game forum would have been considered "not best practice", even if it worked out in my case), and all the data about my education would have been at risk of breaches like this.

I think it's inevitable that once this data is out there it will get used too, especially in the US where privacy protections are lower, but even in the land of GDPR I've encountered some recruiters emailing me at addresses that they could only have obtained because the companies they use to source emails ingested the Gravatar leak.
Hi Krishna, congrats on the launch!

I really like that you have the 'try with no credit card' offering, I wish more companies would do this.

One question I'd have for you is how _your_ services are hosted. If my service is hosted on AWS us-east-1 and so is my monitoring I'll be worried that I'm not going to get alerted when AWS itself has problems.

It seems to me that you're entering into a crowded market. I can think of a dozen or more companies with similar offering. How do you plan on differentiating yourself? Who is the target user for your product and why would they select it instead of a competitor?

I replaced the failed ribbon cable with small wires on my ti-83+ probably 7 years ago now. It was pretty straight forward. I've used the calculator maybe once since then, but I keep it around for nostalgia.
I bought a Xiaomi model for $400 at Walmart, cut a QR code off an Amazon package and taped it over the power button. I left it out in the open next to the bird scooters in LA wherever I went and lasted about 6 months before somebody scooped it up. I assume the rest of the time people tried to scan the QR code and assumed the app wasn't working. :)
We (Latacora) previously advised clients to encapsulate GhostScript processing in something with a hard security boundary (like a Lambda) and I am not expecting the new implementation to change that.
Using an empty base class is idiomatic C++ for solving the problem comex is talking about (marker types) although it has some pretty annoying consequences. Whether it's "simpler" probably depends on whether to you "simpler" means, "how I'm used to in C++".

But it doesn't have any bearing on the problem I was talking about, if you were to instantiate your empty class it has non-zero size. C++ just doesn't have ZSTs.

More likely that Google engineers are in a bubble because of all the available internal tools. Also the interview process nowadays select people that have time to train for the interviews rather than good engineers. The Google interview is still hard, but not for the same reasons than in early 2010.
For all the people somewhat defending the VC's: Nah.

One point I haven't seen here is the extent to which these things just littered cities; there's something of a "tragedy of the commons" type argument here.

Honestly, I'd be interested in favor of a bigger movement for individuals to hack and "steal" them for keeps.

(Note the quotes around steal, please. I am a lawyer and I do not believe I am inciting an illegal action because I believe there's a very strong legal argument as to their status as mislaid or abandoned property.)
And airplane luggage weighs 50lbs, and I carry that around for extended periods of time, depending on the situation.

E-scooters are much smaller than bikes in my experience. Bikes are lighter, but the bulk means that you can't take a bike into a typical elevator for example. I know they make some very small city bikes but even the smallest bike seems bigger than a scooter.
Name another 7-year-old home wifi access point that still gets manufacturer software updates. The contemporaneous Asus RT-N66U stopped getting new releases years ago and in all likelihood contains a bunch of vestigial vulnerabilities. OnHub got scores of software updates over its life and the only time they had a CVE it was patched and pushed to all hardware globally in less than 24 hours. I don't see how this model of control is not clearly superior.
I guess my point is that if you want to break the law, things that you own shouldn't prevent you from doing so.
They eventually gave just a "tell us you're doing personal use and we'll move you to a new free plan" option. That's what I ended up doing: I figured at least I'd wait until the end of their period to do anything.

I don't remember if they offered an option to go back if you'd already upgraded, though.

But yeah, this is the basic kind of weird and unfortunate scenario their muddled messaging led to.
Thanks. I did not know about this one. Looks interesting and I will explore the website for details.
The point is whether it's a fair comparison or not. If you allocate enormously more land and money to one mode of transport, no shit it'll probably end up more attractive.

If there were as few dedicated, reasonably safe car lanes as there are bike lanes in the US, hardly anyone would drive, either, unless they really had to.

> Cars are larger than bicycles, so I would expect their infrastructure to take up more space.

That's just an inherent disadvantage for cars, just like being slower is an inherent disadvantage for bikes or walking.

You're basically suggesting that we should forcibly remove the car disadvantage, while of course the disadvantage for walking and biking has to stay. It should be obvious why this makes for an unfair comparison.

Generically: Don't make your important product to get out there the first product you try to get out there. So business structure first, then important product or service.
Cheaper housing and better social programs together would be great.
Yeah, when I used it the first time I was in awe, but over time I removed their apps and I just walk to the supermarket.

Their prices are quite high, delivery time is unpredictable (even though their app says 10-15min, sometimes I had to wait 30-40min), and their inventory is limited. I still use them once every 2 months or so, but on a weekly basis I'd just rather go to a local supermarket myself.
Can we please stop talking about Tokyo housing. It was only a few decades ago that California was cheap and Tokyo was insanely expensive and locals couldn't afford it. 30 years of economic depression has created cheaper houses.
You're being downvoted but this is especially true of open source projects. Raising money ties the future of the project to the future of the commercial endeavor and misaligns development incentives.
The sweet spot for scooters/bikes seems to be as a tourist attraction.

I live in Toronto and there is a rental bike thing with bike docks. The bikes are shockingly heavy, the phone app sucks, but they remain popular. I attribute the success to summertime tourism.
Lol, unfortunately I think you just missed it. Software-wise, the TI-83 was nearly identical to the plus. I actually had a later revision of TI-83 that had an identical housing to the plus, but with differently tinted buttons.
Also I always wonder about margins. They have software component, but they also have rather expensive hardware. And then overhead of management of that hardware. Like paying people to relocate and charge them as needed.
It's probably going to break something when they clean up the legacy stuff too. When you keep around something for that long while building something new, the roots tend to grow into each other.
You think it's a possibility that a large C project is bug free?

I had a TI-83+, not a TI-83, so I can't be sure but I suspect you're misremembering which feature was missing: The + did have while loops but didn't have functions, but calling another program worked like a function call with no parameters and no return value (and you could fake both by using the global variables).

Why is this Harrison Bergeron-style "solution" to things so common these days? "A lot of people choose X over Y, but we want more people to choose Y over X instead. Make Y better? Unthinkable! Let's make X worse instead!"
Using C sounds like it will bring a whole new list of exploits with it.

Not good!!

This feature is something I always wished to see in FOSS world.

Private package registries unlock a TON of value in companies, and having Gitea propose it just makes sense, to move away from a Github-only world.

Let's hope they add some of the killer features like repo-proxying too, and it'll really challenge some of the bigger players (JFrog, I want to love you, but you make it really hard sometimes)
Browse through https://en.wikipedia.org/wiki/Category:Wikipedia_neutral_poi... and you'll find plenty.

For example:

> Mohammed Zakir (also known as Meyra) was an Ethiopian Oromo nationalist. Regarded as "legendary Oromo hero", he is noted for his high contribution to keep the lights of Oromo nationalism shining after the martyrdom of his two hero colleagues called Elemo Qiltu and Ahmad Taqi ... the Oromos would never forget this early exemplary hero. And above all, history will always remember Meyra and his heroism.
I've heard of three different companies offering e-bike leases, with the monthly lease payments eligible for commuter reimbursement by employers. It seems like a good business model.
The xdg-shell protocol is a sort of core desktop protocol. It has an opinion about everyone's favorite Wayland topic (server-side decorations), and if you have a different opinion, you need to use the xdg-decoration-unstable-v1 (as it still seems to be called) protocol. Fortunately, it seems like the Wayland desktop scene is converging on that one now.

There are still some missing pieces, but the situation isn't disastrous anymore.
> it’s the convenience of being to pick one up anywhere and drop it off anywhere

Sure _if_ there’s a scooter nearby _and_ it’s charged… Then there’s the issue of needing a half dozen scooter apps all to use / find a scooter near you. The problem only becomes worse if there’s a group of people… These scooters are mostly just expensive trash laying around cities.
> I don't think $2000 and under devices belong in the rental space, in most situations.

Taking this completely out of context (i.e. I'm not debating the original point, just saying it for the purpose of sparking potential discussion) - this doesn't extend to other industries. In particular, a ton of photography / videography equipment for rent is under $2k.
WUFFS seems like a great option for this.

That defeats the whole point of a private company, and take away most of the benefits. The thing with the scooter business is that there isn't really a moat for it. Any number of players can come into the market(and they did) and just run the price down the bottom. But by that point a company can probably IPO and transfer the risk from the VCs to the public market.
Because the infrastructure spend and land allocation is not evenly spread. In most places, there is a dedicated lane for cars heading each way, possibly with parking or at least a decent shoulder on either side of the road.

The same cannot be said for sidewalks and bike lanes, which may be non-existent or poorly maintained, and certainly never take precedence over the almighty asphalt.
Are we talking about the same scooters? They usually weigh c12kg and are very unwieldy to carry.

(Basing this on a Xiaomi Mi M365 which is one of the most popular ones)
Would love to see the numbers which they surely had showing how many instances were still running on Classic over the years.

The superior pricing of new instance types that needed to be on VPC was probably as big a factor as anything in pushing people off, but there must have been lots of servers just clicking away with no one really paying attention to the billing.
That was exactly my point.

Either way, at this point this is just two non-sex workers (i assume) saying what they think sex work is like, so i don’t think there’s anything more useful to be said without someone with direct experience joining.
Similar feelings here. When the project started to become more well-known I was paying attention - it seemed obvious that a digital currency would be useful for many things.

I didn't mine, I didn't buy, but I thought it was cool. Over time it started to become a big deal when more and more online services started accepting bitcoin, and it just seemed like it would become more and more useful.

Now? It's all HODL and online scams.

I think in the future we will have some digital currency, but it won't be bitcoin, or anything else we have at the moment. There are so many ways it could be used, from micropayments for news, to cross-border payments. But having seen all the fallout from current systems it will probably be a long time coming..
It's OK, we don't use that either. I think I had lots of issues trying to set up the GitHub webook and I abandoned that as well, sadly. It was fairly easy to set up the main UI otherwise, though.
GitHub is the system that broke. All the communication systems within it needed to be disabled for custom notifications since it would otherwise be too noisy.
Fair, I'm definitely talking about the execution of the "dump VC on it and winner take all" strategy that would have only worked for Bird or Lime.

Also, as a personal aside, I actually enjoy the product a lot. Whenever I visit San Diego or Austin, those scooters make getting around downtown a lot more quick and fun and it's absolutely worth $3 or whatever to do it. I do of course get the point that my personal anecdote does not a plausible unicorn make.
