If the thing you care about is clear sidewalks, scooters are such a tiny problem that they're barely worth mentioning. I've had to step over parked scooters a handful of times. Every time, they were in an alley that no wheelchair or blind person could have navigated. The sidewalk was also populated with garbage cans, bicycle parts, and some random trash.

If a scooter is poorly parked in a high traffic area, people tend to move it out of the way. If it's in a low traffic area, then there's almost always other stuff in the way as well.
I mean, there's still a whole 50% of humans to market to in that case. Nevertheless, while men's color perception is typically worse, it's still good enough that a man with full color vision can see colors that humans can't reproduce faithfully.

There are plenty of boards that are much more powerful than the RPi and have comparable price (ODROID-C2 comes to mind). But the devil is in wether or not they run the mainline Linux kernel.

I have several ODROID-C2 that I have replaced with RPis because of the poor hardware support (Amlogic kernel was way late at the time, may still is).

Stick to mainline.
Amazon never discloses numbers - the exact quote is "over 100 million".
Here is the only real solution:

Have a browser which intercepts requests and encrypts all of them with your public keys, which can only be used to decrypt stuff on the client side.

Wesites would have to start indicating that they understand this new contract and that their servers won’t understand ANYTHING.

It could be a new protocol like https but called something else such as shttp:// or encrypted://

All apps would be client side and in Javascript. Yes, servers will be relegated to dumb boxes like in SAFE network. The business model can no longer be about capturing your data unless you share the data with another participant in what is essentially your web based VPN.

Any encrypted:// site can only load other encrypted:// resources so it can’t send any info to the server via postMessage etc.

There would be no cookies. Sessions would be kept on the client side, as they should be. Using sessionStorage.

Business logic done on servers now would be pushed to the edges, or could be further secured by validators that you allow into your VPNs and group activities.

People would share keys to group activities.

I am talking about somethig that breaks the current Web. No more cookies. No more AJAX the way you know it. Files are loaded from static bundles loaded ahead of time, before the website can learn custom information about your user agent.
I guess it depends heavily on the locale - I live in Portland, and while we're one of the most bike-friendly cities in the US, going helmetless would be risky at best, though outside city limits wouldn't be as concerning.

There need to be penalties for knowingly putting unenforceable terms in employment contracts. Too many companies subvert the law by putting unenforceable terms in their contracts and knowing that most employees will not realize that the terms are unenforceable and that most of the rest will be too afraid of being sued to break the contract even if they know that they would eventually win in court.

There is an idea that the runtime could be hosted from a common CDN and then cached by the browser across applications so you only have to download the runtime once. Combined with browsers caching the compiled versions of the wasm modules, the cost of the large runtime might be pretty minimal in practice.

If you constrain "reality" to the LinkedIn list[1] that Jeff referenced, Amazon is #1. If you drill into the urls and read the LinkedIn ranking methodology[2], you'll see it's based on views of the companys' job listings and career page.

If it was a ranking based on The New York Times stories and reader comments, Amazon would definitely not be #1.

Yes, when Jeff translates LinkedIn's limited criteria into "the most sought after places to work for professionals in the United States.", he's editorializing. That's not too surprising since it's a letter to his fellow owners. Cheerleading is to be expected.

One interesting aspect of red pigment usage that I feel this article could have explained better is why it fares poorest under the sun: of all the color pigments, it absorbs the most of the short-wavelength (high energy) light. Now, you'll naturally think, "but what about black?" Well, most of the black pigments we use are very chemically stable materials, like powdered carbon or some iron oxide compounds.

(Once you know this you'll suddenly start to see how a disproportionate share of red cars have failing paint -- particularly after sometime around the early 1980s when the use of Cadmium pigments started to fall out of favor for most uses.)

"You can consider yourself a person of high standards in general and still have debilitating blind spots."
"To achieve high standards...you need to form and proactively communicate realistic beliefs about how hard something is going to be..."

We’ve been working on Radar, and releasing updates and improvements, continuously since we first launched. What we’re announcing today is (1) a completely revamped machine learning system (which we couldn’t release in pieces—we needed to finish every layer of the stack before we could launch it, though we’ve been running it in beta for a percentage of users since late last year) and (2) a new package of features specifically designed for teams working on fraud prevention.
Maybe the missing feature here is that GitHub should "just" automatically minimize +1 comments. Or even better, delete them without sending a notification to maintainers/watchers, and automagically have the user who posted it add a thumbs up to the original issue.

(Personally, I would consider them spam.)

According to Wikipedia their profit was 3B last year. If they have 566,000 full-time employees at 2,000 hours each, that is 3 billion USD they have to distribute to 1,132,000,000 hours, so they could raise the wage of each employee evenly by around $3 an hour, and would then make $0 instead of $3B.

When a company has this many employees (compared to some other large tech companies like Facebook with only 25,000), the math isn't as nice as you might imagine. Amazon has very low margins.

Yes, VDO is transparent for the layers above, like filesystems. XFS+VDO might be preferable to BTRFS, if it has the features you need.
- LVM could be used for snapshots, but the snapshots from BTRFS might be preferable in corner cases where many snapshots are done (snapshots in XFS are being worked on AFAIK, these could then be comparable)
- XFS+VDO combination might be more reliable, it's a completely supported combination on RHEL, whereas BTRFS is just techpreview
- only missing feature coming to mind is checksums over data blocks, XFS is only providing checksums over meta data

There's no immigration controls between the states because we're all part of the same country. Don't think it'd even be legal to try it, ever.

The only real "immigration controls" we have are for produce at the California border to control the immigration of insects, people are free to go wherever they want. Oh, and those annoying Border Control checkpoints not at the actual border to impede the movement of foreign nationals.

Amazon does a 2 year sign on reward, the first year in bulk the second year in monthly increments. No other company does that, but all we ever hear about is the vesting schedule.

When all is said and done, Amazon pays a little less than Google/Facebook (the caveat here: most Google/Facebook jobs are in California, not Seattle), but with the stock performance we're seeing, they end up making more on average.

The question, is when Amazon's stock stops appreciating so quickly, is other comp going to make up for it?
Based on the price of prime, they’re pulling in like $6-9 billion per year on that. That’s crazy. Of course that goes back into shipping costs but still.
I don't think it ever happens though. Browser vendors focus on performance, and any of these limits would mean degraded experience from the point of the view of the user.

> American jets need a shiny aircraft carrier and a coin can mess them up

Now it sounds like you're trying to claim that you weren't including American Air Force jets in the term "American jets". I'm not sure how anyone was supposed to know that. Without additional qualifications, "American jets" clearly includes Air Force jets. And, again, Air Force jets generally do not take off from air craft carriers, shiny or otherwise.

> Many branches of the American armed forces operate jets

> Allied countries also operate American jets, even the F-35.

> The F-35 has many variants, and can fulfill many roles

Yes. Those are all facts. Facts than have no bearing on your original post.

It's ok to admit you were wrong, you know. It doesn't reflect poorly on you.
> In Austin, many bike racks also are coated in bird poop, though I'm not sure what can be done about this aside from regularly cleaning the racks. I never ran into this problem anywhere else.

Presumably because the racks are underneath trees or shade (which the grackles also like) to avoid baking your bike in the sun.

Austin gets really hot in the summer and non-reflective surfaces can get hot enough to impart burns.

Well there is a massive bias straight off.

Nobody arrives at a post at random, nor will the toxicity be uniformly distributed.

When the net/web was first rolling out (or my first exposure to it), I recall thinking, "This is it, universal communication, no more politics/propaganda/dark-ages-of-information-is-over etc".

Then we got Google, Facebook and the cadre of TLA's and criminal orgs turning it into a panopticon and a tool to manipulate people.

I think no matter what technology or tool we create, it'll be abused because that's the society we've created - one that encourages and rewards this behaviour when performed by a small group of very greedy, very misanthropic people.
Stock aside, they still pay healthy tech salaries, well over those of many professions in America. The stock is a bonus over that.

I have a 20 month old kid, and in my experience out and about the town, meeting other parents, going to the playground, etc., in general I find that many (most?) parents (especially of the well educated / middle class or professional type) err very far to the other side.

That is, they follow their kids around closely, telling them what to do or not to do 200 times an hour, and not letting the children try anything for themselves. «Don’t climb down those steps. Don’t climb up the slide. Don’t run. Don’t pick up those rocks. That candy wrapper is trash don’t pick it up. Don’t put the stick in your mouth. Don’t step in that puddle. Stay far away from that dog poop. Stay on the path. Don’t kick that ball. Don’t borrow that toy, it’s not yours. Share your toy with the baby. Oh you fell down you’re okay you’re okay. Oh someone took your toy you’re okay you’re okay. Eat this or you won’t get that. We need to leave now, get in the cart.» And on and on. For the kids’ sake I wish the parents would just shut up and let them explore sometimes, and would explain their boundaries instead of just saying “no” to everything.

The poor kids then get scooped up and carted around in little strollers, often with their vision obscured by a canopy, strapped in, not interacting with the world or with people and with no personal autonomy. They then get transferred to a car seat, again strapped in and bored to tears as they are driven around town unable to see or interact with anything. The modern suburban lifestyle is terrible for small children.

The job of parents is not to shield their children from any and all stimulus because some of it might carry minor risks or be a minor inconvenience to someone else, but to help them get as much meaningful feedback as possible from their environment while not getting grievously injured. Parents should interact with their children all they want if that interaction comes in the form of talking to them, playing games, dancing around together, running up a hill, reading stories, building things, etc., but when the interaction consists largely of the parents exercising control over the children (and in my experience often otherwise glued to their phone screens), it’s really sad.

Ask HN: Does the Flesch Readability Test Matter?
I've seen it mentioned a lot when it comes to content writing tips online, and quite a few SEO plugins like Yoast grade your work on it as part of their toolset.

Yet at the same time, I've never really found any evidence it actually makes a statistically noticeable difference to the popularity of a website or article. Every news site I went to failed miserably when random articles there were tested against it, yet I didn't seem to notice any correlation between the resulting scores and the popularity/reputation of the site in question. Their SEO wasn't being hurt, the people in the comments and social media didn't care less and everything else just seemed normal regardless.

So does it matter here? Is there a study showing sites or publications with a better score on this do better in some way?

Does anyone know?

I heavily vet sources first. Reading reviews, reddit threads, about the author, looking at the curriculum, etc. Youtube and udemy have a lot of bad stuff - but there are gems as well if you're willing to wade. I've used pluralsight in the past, it was pretty good. Again, I vetted their stuff before choosing which courses to watch. I have a list of resources for learning various things, that I've been compiling for a while now. 90% of the content is free - and that's not because I have anything against paid training.

First, sensitivity to initial conditions is a necessary but not sufficient property for chaos. Some sort of folding/mixing is also necessary, which can be gauranteed by a bounded state space.

Second, it's definitely true that information processing systems, if they are to be reliable enough to be useful, are not going to be chaotic throughout their state space. They need to return the same output given a certain input. But I'd imagine there are also at least a few noisy regions.
It may be location dependant, but IMHO any corpse in a morgue would be full of preserving chemicals to ensure it'd be "presentable" for the funeral, and thus inedible.
Your employer will agree to their terms on your behalf, and if you are not comfortable with either that process or the terms, you are welcome to terminate your employment. This is no different from companies accepting ToS/EULA from any other technology vendor.

Most likely the same CYA reasons they would have also implemented the Cookie Disclosure in recent years. Even if US-based and expecting primarily US-only traffic, major company doesn't want to be legally liable for any issues arises with EU compliance, just from curious visitors. (Not to mention the obvious gray areas of EU citizens residing in the US.)

The more hopeful answer is that possibly because of GDPR and indirectly recent Facebook/Cambridge Analytica, at least some companies may be doing it simply because it is a good idea, whether or not they think GDPR applies to them.

When working on a new app I don't always know the exact DB schemas I need. Maybe my mind is mush, but I have a feeling lots of devs deal with this.
