Brin’s airship was originally intended to use hydrogen as a lifting gas.
Hydrogen is much cheaper than helium and provides more than 10% more lift,
but will forever be linked with the infamous Hindenburg disaster in
New Jersey in 1937 that claimed 36 lives.

First of all, the true cause of the airship fire is still debatable. According to retired NASA scientist Addison Bain's incendiary paint theory (IPT) proposed in 1996, the Hindenburg would have burned even if it were filled with helium. So by switching to Helium as the lifting gas for airships still may not make it 100% fire-safe even in the example that was given.[1]

Second of all, Helium is a RARE natural & non-renewable resource (it cannot be artificially produced, at least not yet), albeit abundant on Earth. Most helium on Earth is a result of radioactive decay, which occurs for a long long time.[2] Hence, I think most Physicists would argue the usage as a lifting gas to commercial airship is a wasteful and eventually non-economical way to consume them due to the sheer amount and no practical recycling measures.[3][4]

>Out of curiosity, what are the ethical concerns? The arrangement is not being made by the middleman company. I don't see how it is unethical to not pay them for something they did not do.

Their service was connecting drivers and riders -- allowing them to find each other for the transaction. They connected you. That was their service. (They provide other related intermediary services, but the "finding" function is the big one.)

Same issue as when a recruiter finds leads and the employer makes an offer to the employee directly and cuts out the recruiter, which is why they set up a bunch of contractual barriers to stop it.

EDIT: Sorry, I misunderstood the use case -- that wouldn't apply to future bookings after the first one's been completed and they've exchanged information. But the "moat" there is the difficulty of iterating through your network of past uber drivers for each future ride.

>Point (B) doesn't make sense to me. Why do you have to accept and then cancel? You just get the driver's phone number and talk to them directly.

AFAIK, they don't give you any way to contacting each other until the ride is accepted. Am I mistaken here?

>If you're instead saying that drivers are employees of these companies, then maybe you're right about all the rest of it. But you can't have it both ways!

No. You can have a legitimate claim to compensation for connecting two people without the seller thereby being your employee -- see the recruiting example (though it's a bit confusing in that there is another employment relationship in the picture but I'm sure you see the mapping -- a recruiter can legitimately claim that they're owed a cut while not saying that their the employer of the, er, hiring manage or the candidate).

EDIT: As above, that wouldn't apply to future rides or job offers after that contract.
You are thinking too broadly about learning styles. Things like practice/hands-on-learning are one good way of teaching, for example.

It's not learning styles as in different styles and methods of teaching and learning that have been debunked. It's Learning Styles™ that have been debunked (i.e. Auditory, visual, kinesthetic).

So what - will companies stop producing non-self-driving cars? Will regulators force that action? I can't see either happening if self-driving cars have major limiting factors like that.

The alternative to self-driving cars that behave badly is not necessarily other self-driving cars, but simply non-self-driving cars.

Sorry, a quick search doesn't turn it up. This is from memory. Microsoft's strategy - from their own memos (maybe the Halloween memos?) - was to "try to make using Netscape a jarring experience". They were paying (maybe in equipment or some kind of freebies) websites that included at least three IE-only elements in their pages.

This was not just competition. This was a deliberate campaign to break the web in a way where IE would work but Netscape would not.

As I said, this is from memory, and I can't find the source. I have read a copy of the Microsoft memo, though (but you only have my word for it...)
I doubt they ran into trouble because of their planned sales model. Fundamentally this is not a product I would expect to be commercially successful. All these weird trends like Kickstarters for "Connected bikes" and Bluetooth "smart locks" are not actually very useful to cyclists. Real improvements to cycling will come from investments in infrastructure, not by throwing technology at bicycles themselves.

What are your reservations about a B-corp?

Nonprofit legal status is hardly a guarantee of anything about corporate behaviour, aside from what paperwork they fill out.

I wish there was a tool that would turn my smartphone into a dumbphone (only capable of texting and calling) for a period of time and the only way to unlock it would be a factory reset. I would like this for my PC as well. That would be some deep space.
Before anything else, try asking yourself a slightly different question:

If you were given when you were a kid a laptop or tablet (and if internet existed at the time) would you have used it to study or to look around for (choose whatever fits better) music, movies, lolcats, funny videos, maybe some p0rn and the like?
Yep. "The line ups might come back". The reason there's no line up this year isn't because there aren't enough students, it's because BC has done away with first come first serve, and is now doing a lottery system.

I did as thorough a comparison of translations of Meditations as I could as a non-Greek-speaker a couple years ago, and settled on Maxwell Staniforth's for being highly readable while also holding much closer to the original than most. The only hardcover available (at that time) was from Folio Society, so a little pricey even used, but I'm pretty sure there's at least one paperback in print.

There was, notably, one popular recent translation that tried to give it more of a "quickly-jotted notes" feel to capture the flavor of the original, or so it claimed, implying greater fidelity to the original. In doing so it took far too many liberties with the text—which, to my Greekless eye aided by some online tools, didn't read that way at all, and was typically much wordier than this translation and generally closer to basically any translation but this one. Be wary of anything like that.

Just throwing that out there in case anyone finds it useful.
Sure, but not many have gobs of documentation, regularly updated OS distros, and a rabid community of coders, makers, educators, etc. That Raspi B you bought five years ago is still supported by the latest Raspbian releases. Not many other boards will have that kind of long-term support.

Until there's a (well adopted) common platform standard for these ARM-based boards, the Raspberry Pi Foundation must continue to develop their hardware. Unless... perhaps Eben and Co could work on that standard, and its adoption, as part of their goals.

"It was October 4th, 1957. Scientists at MIT noticed that the frequency of the radio signals transmitted by the small Russian satellite increased as it approached and decreased as it moved away. This was caused by the Doppler Effect, the same thing that makes the timbre of a car horn change as the car rushes by.

This gave the scientists a grand idea. Satellites could be tracked from the ground by measuring the frequency of the radio signals they emitted, and conversely, the locations of receivers on the ground could be tracked by their distance from the satellites. That, in a nutshell, is the conceptual foundation of modern GPS."
I waited in line to reserve a model 3. Pretty disappointed by the news lately.

It's pretty much a given that the first release will have some problems but add onto that the complete bareness of the model 3 base model and I'm scratching my head whether this is worth it.

If it's going to be close to 50k for a model 3 with autopilot I'm probably going to cancel. EVs are nice but I don't have loads of cash to throw at them.

I also had a weird issue where for certain packages yarn would pick up a version which was older than what npm would. Not sure if this had anything to do with the fact that we have an internal npm mirror (that being said, yarn claims it picks up the .npmrc information, so even if it did, that would be a yarn bug).

In addition, yarn seems to increasingly be prioritizing its own default configs over what may be saved in my ~/.npmrc. Had several proxy issues after upgrading to a newer version of yarn that I didn't have earlier.

The reason I switched to yarn wholesale was because my existing npm based infrastructure worked seamlessly (at least to the extent that I was using npm features). But I've noticed that newer versions of yarn seem to have regressed in terms of npmrc support, which is a huge problem.
>I'm pretty sure no one who uses Google or Facebook is presented with a dialog that says 'This service is free in exchange for your privacy. Do you agree?'

3rd graders in my state take the PARCC exam which is done on a laptop or chromebook. So there is a push to make sure children at elementary school are familiar with such computers including typing practice. This makes sense.

I've learned 4 languages now.
English - only language my parents spoke.
French - did French Immersion
Finnish - spent time in Finland in my teens and learned the language
German - just started picking it up 3 years ago

The main difference I see is 2 things, time & immersion. I know less German after 3 years than I did through French Immersion, but I've spent way less time doing it, never had any formal instruction, and haven't spent 7 hours every week day having to talk and listen to German. I know more German than Finnish though, simply because I didn't spend as much effort actually learning Finnish, it all came from immersion.
Dopamine seems to be an API that automates and optimizes the display of "rewards" (positive messages or images) in an app to increase usage, right? And there's ML to optimize timing of the rewards, but it's basically exploiting the same effect seen with randomized rewards, i.e. the thing that makes gambling addictive, right? Is that a fair summary? That doesn't seem like it's giving "an individual autonomy over attention". It seems like the exact opposite.

I don't understand what the other thing, Space, does. Does it just interrupt social media apps periodically? It seems more like an attempt at viral marketing for Dopamine than something that's intended for real people to use, but I can't tell what it does and I'm not on iOS.
Sorry, I did not intend to conflate immersion with charter

I think it depends entirely how they are used.

CAD (Onshape), programming, digital arts/photography, making video, collaborating on writing and presentations for group projects, collaborating with your classmates, doing research -- all great uses.

In other words: classroom tech is probably best (IMHO) when used in nearly the same way you would use it in a job or a non-school project.

Replacing existing educational systems and tools (conventional textbooks, testing, etc.) ... probably less useful.
This myth has always particularly annoyed me. It's like when people say "I'm a visual learner". Of course you are. You are a human being. We all learn things more effectively when they are displayed visually in an intuitive way. It's the same mindset that feeds into people thinking they "just aren't a math person". You're not special, it's just pop science BS designed to make people feel better in their laziness.
Where does that support the claim that
Debian would oppose people working on
sysvinit support?

In the body of the other[2] email where 'Option 2 "Support for other init systems is recommended, but not mandatory"' was selected by the Debian community. Once this path was chosen, while it theoretically isn't opposition, in practice it was only a matter of time before non-systemd init systems would become increasingly difficult to use in a systemd-leaning distribution (sysvinit or otherwise).

As Manfred Eigen said:

In theory, there is no difference
between theory and practice. But,
in practice, there is.

That is, that's all it takes if the child values learning. If not, well, plenty of children manage not to learn in schools, too.

> Some learn better visually, some kinesthetic, some auditive.

That's the exact myth that actual research has shown is mostly false.

> This doesn't mean someone is exclusively visual but there certainly are preferences.

There are certainly preferences (in some part, this is a product of people buying into the myth), but the research keeps showing that catering to those preferences doesn't actually improve learning, and actually makes it worse compared to balanced approaches which address multiple modes rather than focussing on a learners perceived "preferred" mode.
I did not know (but am not surprised) to know that 'attention engineer' is a standardized job description now, or indeed that there's a whole field of neuroeconomics - most interesting. I can't help noticing that your two tools seem to be directly opposed to each other; usedopamine offers to leverage dopamine hits for commercial purposes, whereas youjustneedspace seems designed to insulate users from exactly that problem - I hope. If the two are designed to complement each other in order to increase the commercial payoff of individual dopamine hits then I would have to question whether you were being altogether straight with users of the latter tool.

You may find my other comment on this post interesting or boringly obvious. I'm fascinated by what you're doing here but right now I'm not sure whether I love you or hate you.
This article is so wrong :

* scarcity of French immersion programs are not widespread in Canada. In Edmonton, AB, there are enough vacancies for the interested.

* the article confuses correlation and causality. French immersion students get better grades. But the simple fact that their parents want them in these programs are an indicator that these parents take more care and attention on education. And these parents care is, by itself, an important reason for better grades.

* if so many parents want it and there are clear reasons to believe they're good for the children (better pay) and for the country (strengthen the cultural identity) then the problem is that there are so few, not that they shouldn't exist.

I concur. There's some times that running some JS can make the user experience strictly better without taking up any significant amount of memory/CPU time/energy/network (or in fact makes the system use less of those).

It's frustrating when some site uses lots of JS to just reimplement browser features (like displaying text, showing a web form, history/links) which makes my laptop's fan spin up -- but doesn't bother using JS to implement genuinely useful things like validating the credit card checksum (https://en.wikipedia.org/wiki/Luhn_algorithm) in JS on the client before submitting the form.
