> Gravitational force is both much weaker and (for that of large bodies) diffused over a much greater area than electromagnetic force (of very small bodies).

No, that is simply not true. Not at all. You keep saying this, and it keeps being not true.

I don't really know how else to say it to you. You have a mistake in your intuition.

> Nevertheless, if the total gravitational force of the relevant object from the example (earth) was concentrated into the same area as the total EM force of the magnet, we would have a black hole in our kitchen.

No! That is not true. If you turned the earth into a black hole, and placed that black hole in the center of where the earth used to be, you would notice NOTHING whatsoever in your kitchen. NOTHING. You could not tell the difference.

> Things which are more diffuse are necessarily diffused over a larger area.

And gravity is NOT diffused over a larger area than electric charge.

If you had enough electric charge to pull on you (assuming you were of opposite charge, at the same ratio as your mass vs earth mass) placed in the center of the earth it would act IDENTICALLY to gravity. And that charge would be very small, much much smaller than gravity, because gravity is WEAKER than the electric force. NOT because it is more diffuse.

> Edit: and thank you for the EM force inverse power law correction. I was using distant memories of the math for EM radiation, which is obviously different.

Not EM force. Magnets with two poles. EM force is the regular inverse square.

> But if those numbers are right, it supports the argument that gravitational force is less concentrated...and therefore more diffuse, does it not?

No it does not. It just means you have two opposite magnets that cancel each other out at a distance. If it were electric charge, which is a monopole, it would not happen.
They're putting people out of work by shuttering taxi businesses which traditionally pay a liveable wage and replacing it with something that pays drivers a pittance while directing all the profits to a small handful of people. If they're destroying jobs at neighboring competitors, then yes, some people will be forced to work for them.

You're probably going to post something about the lump of labor, but consider this: demand for jobs is inelastic. When have you ever seen a company prevented from doing business because their wages were too low? As long as there is a job opening, there will be people competing with each other to fill it since we have significantly more people than we do jobs, thanks to our capital-intensive economy.

I consumed huge amounts of music during the golden age of Turntable.fm (and later plug.dj, to a lesser extent). Since totally losing my playlists during each shutdown, I'm wary of any future similar services.

Discovering Bandcamp has been great, though. On the listener side you have a "collection" of music you've bought, a "wishlist" of music you haven't paid for but plan to at some point (most albums are fully streamable before buying), and a "feed" where you can follow artists you like to keep track of new releases. You can also follow other listeners with tastes similar to yours, for which the Bandcamp site provides recommendations. When there's nothing new in the feed, the "discover" tab and the Bandcamp Weekly podcast are both good ways to explore new music.

I would love a device like the one you describe. Having shopped for dedicated MP3 players recently, the current gold standard seems to be the Sansa Clip+, and even that device is relatively dated. As long as it supports normal USB-stick-like file/folder management, without some iTunes clone to wrestle with.

The "applied research" is interesting: https://www.gchq-careers.co.uk/departments/applied-research....

I think the internet archive has some older pages with relevant information.

If this is GCHQ it's gently worrying - a github profile is pretty low on my list of what I want in the way of transparency and accountability.

Indeed, that's why classifying sharing economy workers as 1099's is not right. Some people rideshare as a side gig, but others do it full time. There ought to be a new classification to account for that range.
Damn, I thought the model clubs won this debate 50 years ago. What's the excuse this time? Terrorists making remote controlled bombs? Creeps taking aerial photographs? Kids having fun outside instead of doing their homework? Bloggers keep bringing up interference with air traffic, but that's completely irrelevant. Models are required by law to stay under 500 feet, and civil aviation is required to stay above. Even if there was a collision, it would do no more damage than a bird strike. And birds don't know they're supposed to stay away from airports. Kites, model rockets, and laser pointers are all more dangerous to commercial aircraft than model aircraft.
If you have the cash, we use Turtlebots in our labs. They use ROS which can be programmed in C++, Python or LISP. There's a cheaper similar version that also uses ROS called DeepBot, but I haven't had any experience with it. It looks good from the website though and that price is hard to beat.

ROS is great as the code you write for one robot can be used on another one fairly easily. It's also gaining pretty large traction in industry with companies. I find that Raspberry Pi/Arduino route more geared towards hardware. I tried that route myself and lost interest fairly quickly.

> Nobody is forced to work for Uber.

Some people have invested themselves in Uber based on the pay, which has since dropped. This has happened to people such as Mr. Creery from the article.

Imagine you get hired for a job for some amount of money, pull up your roots and relocate. Then 3 months after you get there they drop your pay down by half. What a pain. Would you have taken the job if you knew that were going to happen? Probably not. And now you have a large switching cost to get away from this job if you have to move again.

Unionized workers can in theory negotiate to mitigate those kinds of scenarios.
I don't think there's really anything fundamental about them that means that chat has to be interactive and email has to be time shifted, I know many people who deal with chat messages in batches much later than they're sent, and people who will respond to email within seconds. I think that's a ux choice, just like encouraging long vs short messages.

I do like your idea of designating a response time, but it probably requires too much from the sender. It might be that you could train rules on the client that could do a good job of working out how quickly things should be responded to so your client could batch appropriately.
This looks really cool.

Do you have a gitter channel or something?

As a rock climber I see this entire 'ropes breaking' discussion very odd. Ropes carrying people shouldn't break. Full stop. There shouldn't be any sharp edges. Weight, even impact forces, shouldn't come anywhere near thinking about breaks. A rope should never be able to slip off a pulley. If it can, then the pulley needs to be redesigned. If it has any sharp edge then it is not to be trusted. Look at the equipment in at any climbing store. You won't find anything even remotely sharp.

Climbing ropes (rock climbing, not mountaineering) basically do not break. An entire system of standards mean that no matter how one falls, no matter the angle and accidental nature, the rope is expected to survive. To see actors hung off systems with sharp-edged pulleys and unconstrained rope movements with little regards for accidental or unexpected forces terrifies me.
In the future, yeah, that seems it will become unavoidable. Luckily for now I was totally able to avoid it, even though I did have to actively seek a new, dumb TV.

I built a "grocery list" app that I can access from my phone. If I'm buying groceries, and I update the list, someone else can view the up-to-date list and won't buy a second carton of milk.
VC / Angel scene is a big issue at the moment, but improving. Capital is tight. That said, if you have a bit of track-record, the 'smallness' of NZ means you can often raise small amounts off the back of reputation. Then you probably want to look overseas for serious money. Or do a Xero and IPO locally - they've shown local 'normal' investors how forgoing profit for growth can work.

Also: the wildlife isn't venomous, the trees are not explosive and the sharks don't bite. Met with a friend from Sydney yesterday - she was enjoying the low 20s here after baking in 30+ in Sydney for the last few days.

Actually, I'm not being sarcastic at all.

I haven't opened too many post-infopocalypse appliances but the ones I've seen have been dead simple, apart from their over-"engineered" control boards. These things used to run off mechanical timers, and that is still the underlying philosophy, with new "smart" features mostly UI-based.

It seems to me that one could design a general sequencing board to run many models. Some types would be harder than others (washing machines with brushless motors), and moreso if manufacturers start to add digitally-communicating sensors, but these don't seem insurmountable to handle pretty generally. So a total end-user installed cost of say $400? That seems within the price differential between "low end" and "high end" models that differ in software.

It just takes will since it requires not just picking from what the advertising says, like anything Free. But IMHO this is a social momentum issue and the disadvantages of proprietary trash-land will only be more and more pronounced as there are ever-more features for manufacturers to fuck up.

And as far as epoxy? Manufacturers don't really care if you mod things they've made, they just don't want to be on the hook for supporting this. The protectiveness is rooted in thinking their shoddy software is some kind of "competitive advantage". Completely replacing the control board sidesteps this.
The Uber policy executive says the proposed Seattle law is “generally believed to be flatly illegal”, eh? I wonder when Uber acquired this sudden respect for the law.

I don't know. The spec I'm working on now is ~1300 lines of TLA+, and that's just the essential core of the thing -- nowhere near the whole program. By comparison, the Raft TLA+ spec is under third of that, yet the Verdi proof[1] is ~50K LOC, took a whole team of experts months of work, and didn't prove liveness.

I have a very small sub-algorithm that I might try proving in TLA+ just to see how it goes.

[1]: I couldn't find the original TLA+ proof online, but the author of the Raft protocol said that he struggled even with partial machine-checked proofs.
That quote is correct, but you need to understand the context: Scott Aaronson is pretty much the entire reason why you can safely ignore any article about D-Wave, because he's the one doing the legwork to debunk their BS. So articles from/about him are exempt.
The barrier to entry isn't high at all. The author was able to create an email client in 3 weeks. That's not a lot of time.

Yes, making a solid GUI app will take a year. But that's the case with any solid app, and I doubt email is significantly harder than other productivity apps.

From your comment below, I don't quite get your characterization of Uber and Walmart as evil.

If anyone's evil, isn't it the government for not providing useful safety nets?

The companies are just going along with the market rates at which their employees/contractors are willing to work.
I gather many drone operators have flagrantly violated the 500 foot flight ceiling.

Perhaps it's more of an issue now because in the days of RC planes operated line-of-sight, you inherently had a tougher time flying high & far than today with live video feed and long range controls.

Isn't one of the main benefits of something like Firebase or Parse that you don't have to run it? It's nice that Kinto packages the stack together and provides plug-and-play APIs, but there's quite a bit of expertise and overhead operating a backend stack in production.
I only do email at 09:00 and 15:00 at the moment, I've never had anything bad come of it. Honestly, if something is time-sensitive high-impact, sending an email in a fire and forget manner is close to a firing offence. That's just not an acceptable way to communicate urgency.

Total NFL revenue is about $7B, total TV contracts per year across multiple networks annualized to about $3B, in the most recent contract. Just a couple years ago it was about half... but we're not in a bubble ... sure ... a 70 year old sport doubled in real value in a couple years, not just bubble doubled in price, not very believable claim ...

If XYZ network could win at a bid of $750M I don't think they'll toss away $250M out of the goodness of their heart by bidding $1B. That's $250M that isn't going toward player salaries, overhead, stadiums, owner profit both immediate and via the estimated value of the team increasing for some future sale, etc. That, is a "sports" problem.

If TV revenue were a rounding error on the budget, variation could be ignored, but its not. It varies from sport to sport but very roughly about half the total revenue comes from TV for most popular pro sports.

On a technicality, there isn't a $1B bid because of high demand for sports. There's all kinds of things in high demand with no functioning market at all. Think of weed, for example. Anyway the football bid is $1B because they reckon they can sell more than $1B in advertising to baby boomer aged fans or other viewers who still have money to be influenced. Betting on TV commercial revenue increasing in perpetuity for all time is not a good bet to make.
Well, you have to pay the registration fee with a credit card. My guess is, they keep enough of that information on file to prove whose card made the payment.

"It is illegal to fly below 1,000 feet"

Where on earth did you read that? Yes, the rule is 1,000 feet above the highest obstacle within a radius of 2,000 feet when over a congested area, but when not flying over a city, minimum altitude is 500 feet.
Oh God, IMAP part numbering. I'd blocked that out until now. And regarding RFC 2047, I still remember when I first learned about RFC 2231. It really reads like an April Fools joke. Actual text from this RFC:

Model airplanes have been around for ages and are generally used by very responsible operators. Local airports and the FAA often have a good working relationship with the local model aircraft club.

The issue with "drones" (which are really just a type of model aircraft) is a wave of irresponsible operators.

The regulators aren't looking to regulate the space because they were bored and looking for something to do. They are looking to regulate the space because there are too many idiots out there causing problems at the moment. If people are going to get upset at someone they should be upset at the people breaking all sorts of existing regulations and causing the FAA to step in to try and get things under control.
If the important part of the bulbs to you is the remote control (and not the color changing part), any generic ZigBee Light Link or Z-Wave light bulb paired with a home automation hub (like Wink or SmartThings) will work fine.
For most people it should be close to a non-issue.

Learn the rules of operating safely, don't be dumb, you'll be fine. If all you do is play with drones recreationally you're not going to run afoul of the rules.

The things that are going to get people in trouble are flying their drones way too high (which isn't easy for a lot of off the shelf drones to start with), or flying in areas where they obviously shouldn't be to start with (rescue situations, controlled airspace, etc.)
I'm not sure what you are angry about, but please let me try and clarify a few things:

>A better app that doesn't crash as much

Working on it. Worth noting that it's free to download.

>Thousands of free decks

Memorang has about 5 million free flashcards currently as part of the crowdsourced ecosystem. You can get content in 4 ways: creating, importing, searching, and purchasing. You can import from Quizlet, Excel, Anki, StudyBlue, and Cram, or collaborate in groups on common topics.

>An open ecosystem

While I think we could do a better job with content discovery, the collaboration tools on Memorang do not exist on Anki. If you wanted to work together on an Anki deck, it would have to be with some combination of dropbox or git. My opinion is that Anki is pretty antisocial.

>Source code

I think HN readers know more than anyone that there's nothing wrong with not open sourcing your company's code. Developers need to eat too. That being said, we are open to making our API publicly available to build learning applications on top of.

>Doesn't spam your email

I welcome your suggestions regarding email and onboarding. Currently we send a welcome email and account verification. Over the course of 1-2 weeks we give short snippets of how to use certain learning modes on the platform. You can unsubscribe from emails at any time via the unsubscribe link or via your account settings.

>Isn't an obvious monetisation of anki's general premise

It's worth pointing out that the creator of Anki has made tens of millions of dollars off of charging for downloads. I'm not sure what "premise" you are referring to - but ours is that the core learning application should be free and not a paid download.

>How anyone thinks that paywalling a bunch of flashcards is a good idea (when anki offers them free) is beyond me

Crowdsourced content is free on both Anki and Memorang, so I think you may have missed that the "paywalled" flashcards are actually an optional upgrade. As a bit of background, we've spent thousands of dollars on content creation and are committed to continuously upgrading and maintaining that content. For example, our USMLE Step 1 and MCAT content are one-time purchases for lifetime access and we maintain updates to stay current with the latest medical information at no extra charge. Users are happy to pay for that level of trust and security.

I hope the above information helps you better understand what we are doing.

Even in the worst case of a quadrotor - which can't glide or autorotate or fly with a missing rotor - a 250g one is not going to become a lethal projectile at terminal velocity. Even the heavy batteries from larger multirotors seem to survive a 100m fall uneventfully, they just make a soft thud when they land. A softball weighs something like 200g and getting hit in the head with one of those at 85 mph doesn't kill you.

1. Let's just assume that unqualified work will always be attractive and that.

2. If you are a big employer you have a big workforce that can, and should be able to wield some power as a collective. The idea here is that a company can't magically dodge having a powerful group of employees by not employing them. Paying as much as you have to means you pay the legal minimum wage, if the workforce as a collective thinks that is ok. Otherwise you pay more.
