That buys you roughly a factor of three.

Subtract again for the fact that you're not shedding half your takeoff weight in fuel over the course of a flight. You land with as much battery as you started with.

More if you're using metal-air batteries.

5 strategies to boost lead generation
Thanks for this. I'm on the lookout for a new Linux to try out, as a departure from my usual Debian and *buntu tinkerings. There were a couple of interesting ones mentioned there that I wasn't aware of—or wasn't aware of what made them 'different'—which I'll have to investigate further.
I guess the more realistic exit strategy in the next ten years (strategic acquisition by Airbus or Boeing to work on their own projects with much longer time horizons) is less attractive for PR purposes...
Electric motors would need to be orders of magnitude more efficient than turbofans (which they aren't). You also need to compare the overall efficiency developed as thrust, not just thermal efficiency.

There's also the issue of the mass of batteries not going away during the flight, unlike fuel, which will require maximum landing weight to equal maximum takeoff weight - this will impose a structural penalty versus IC aircraft.
Breaks observed in Mars rover wheel treads
That's correct, but note that an electric motor is about twice as efficient as a combustion engine, reducing the factor to about 25x (at least ideally). Typical medium range aircraft burn about 3 kg fuel per km [1], so to fly 1000 km you would need about 3 * 25 * 1000 kg = 75 tonnes of batteries. This should be in the ballpark of what we can pack into an aircraft already, but I guess at least another 2x improvement is needed to make it economical (we want to haul some useful payload, not just the batteries).

I think the survey makes a very fundamental mistake in chucking a lot (the majority) of developers under the umbrella 'web developer'. I know they also had subdivisions (frontend, backend, full stack), but in the entire survey they are represented as one category.

Those are fundamentally different roles. Someone working exclusively on server-side applications has a totally different profile than someone working exclusively with web frontend. Concepts, technologies, tools, everything differs, and so probably does the personal profile of those developers.
The founders were very much Windows guys. Their podcast which essentially developed SO in public was very Windows-focussed. Although it's not the case for me personally, I suspect their audience skewed to Windows, these were the early users of the site, and they helped drive its direction.

Although SO now has a much wider audience, the more engaged, longer-term members are more likely to fill out this survey.
I found it fascinating that Smalltalk was #2 as most loved language in spite of its minimal use. Many of the ideas developed for Smalltalk are now commonplace, so I'm guessing that it's the careful integration of those ideas that makes it special.

Have you looked at the build system of a C++ project lately? Or a Java project? It's not like that's some super-elegant not-at-all-rolling-catastrophe of a system.

Java and Node, for example, don't solve anything - to get something that builds sensibly they both entirely depend on "external service" being always available and enforcing naming (see the leftpad fiasco). C/C++ are the source of the term "dependency hell".
What? I had exactly the opposite reaction. Since this replaces the iPad Air, to me this is a return to sanity.

- iPad Pro
- iPad
- iPad Mini

This seems ideal.

If you are a "Pro" you surely don't mind spending a few minutes looking up the differences of the "Pro" model to see if it's something you need.

If you are not a "Pro" your choices are now, Do I want the regular one or the mini one?

Previously non-pros were faced with the conceptually bizarre choice of *Do I want the air one or the mini one?" which sounds like the ramblings of a crazy person.

Like... "Air" and "Mini"... what a weird choice. They both sound like super-portable models. OK. But... super-portable compared to... what, exactly? There were no "regular" models, only "variants." What were they varying from?
I think the image you can see on the electrek article is from this blog post:
https://weflywright.com/2017/02/12/wright-weekly-weport-feb-...

The legend for that image is:

>This image shows the potential subsystems that could be powered electrically. (Note: an fuel plane can also install electric subsystems – for example the 787 is making headway in this direction – but the subsystems in an electric plane will be all electric!)

From what I read from the blog, it looks like they are going all electric. So I'm not sure what magic they intend to use in order to propel the plane, but I'll assume propellers until proven wrong.
At least they'll have a post apocalyptic industrial set for the next Mad Max movie. Just need some pigs to make the gas.

The funny thing is that looking from the opposite perspective I feel the same. The web development looks like going back to beginnings of programming and reinventing everything again in the browser.

You also don't have use for the VCs, so that's a moot point. A business like Basecamp can be started on a credit card, or a simple bank loan.

Can't you checksum verify installers and packages? You can't do that with these curlpipesudos.

You are taking a leap of faith anytime you install something however you do it. The problem with the CPS seems to me that it's much easier for you to correctly trust the originator of the content, but have the content hijacked by a 3rd malicious party.
I appreciate Y Combinator at grabbing ppl attention. We need to do more of this ambitious projects.

However, I'm rather disappointed lack of even fundamental technical vision. I get that if you shoot to fly in a decade you can optimistically base your model on other technical advances (e.g. better batteries), but too much short-term hype can be deceiving.

It will take many years to get there and probably it would be easier to create first small turboprope electric plane. Something like:

Apple Maps?? The competition is so much better.

For offline navigation in car: HERE WeGo (maps.me also works, but HERE WeGo is way better).

For offline navigation on foot in cities: maps.me (also HERE WeGo works, but I think maps.me UI is better for this).

For offline open street maps suitable for offroad: Pocket Earth (works particularly well in Europe).

For offline maps in general suitable for offroad: Gaia GPS or the lower cost Topo Maps (works particularly well in USA).

And if you are into serious off-trailing Gaia GPS (and probably Topo Maps too) allow you to use your own maps as well.

I use it currently for security cameras as well as some lighting fixtures and electrical sockets. For the lighting and electrical I use zwave products and VM on my home server with a USB zwave dongle as the controller. This won't work for a product that has a "cloud" access requirement but it works fine for my purpose. I wouldn't buy a security camera that uploaded images of what I'm up to in my home to anyplace, nor would I use lights that required a AWS instance to be up to turn on. It takes some research before buying to know its going to work but Amazon's returns department has been good to me when the description was unclear. Its much more work than you can expect the average consumer to put in but at this point in my career my money is worth more than my time.

The convincing reason is that you get several automated behaviors in fetching, installing and building this way.

Show HN: Remote Friendly – a site for finding and listing remote-friendly jobs
If you wanted to be sure it was warranted, take a look at the seller's feedback prior to leaving yours. If there's a hint of buyers with similar issues - fire away with a clear conscience.

If you've opened a dialogue with the seller via the messaging system, you should attach a picture of the item with its packaging. IF the seller is innocent (and consistent in their processes re: labeling), they might be able to open a case with Amazon along the lines of "this was commingled inventory - we always apply our label vertically over the item's barcode and our customer received an item packaged with the barcode applied horizontally...therefore you sent the customer another seller's inventory."

That would be a semi-tenuous case to make, but would have a flying chance of working, particularly if the seller had an inbound shipment for the same SKU that was due to arrive at an Amazon warehouse and had left prior to the customer's issue surfacing.

In general though, if there's a shred of doubt...don't worry about the innocent seller. The seller (hopefully) has enough sales volume that your feedback will be lost in the crowd. If not, well, maybe they aren't a good fit for Amazon and you're doing everyone a favor.

There have been several historical studies done on the effects of patents on innovation, and the results are mixed. For an example of the "patents may hurt innovation" side, see http://levine.sscnet.ucla.edu/papers/ip.ch.1.m1004.pdf , which argues that the steam engine patents actually held back the development of superior steam engines, reduced the total horsepower deployed, and even distracted Watt (the inventor) from his business.

I've seen more detailed studies of patent history (which I can no longer find, alas), and they make a good case that patents have an ambiguous effects on industrial innovation. I'm not sure if I believe these studies, but I don't think it's an open and shut case either way. Also, steam engines may have different issues than drug development, and drug developent may have different issues than software.

It's a hard problem. I can't think of a way that doesn't involve destroying a physical copy to OCR, and that's a lot of manual effort.

I've worked at places with serious quality management systems, the problem isn't hard. The answer is easy and obvious: incoming inspection.

Unless "scale" means the percentage of product that passes through inspection is zero. In which case the problem is only hard because the problem isn't how to do something, the problem is how get the benefit of having done something without doing it (whether through inspection, not co-mingling, etc...).

In the case of No Starch Press, the build quality issues were noticeable without scanning the book. And even cutting the spine and covers off of a book to scan it isn't that much manual effort with the right hardware. One of the offices at my college had the cutter and bulk scanner, it was so not a big deal for them to use that they'd digitize a semester's worth of course textbooks for anyone who asked.

Has anyone noticed an extreme explosion in languages? It seems like a good hobby project to create your own language and then evangelize evangelize evangelize.

I'm sure I could keep going, but that seems to be the trend lately. You can't be a big company and not have your own programming language.

So I guess the language changes for each domain. There is no longer the dream of a single language to unite all the plebes! Maybe it was a dream anyways.
