The author ignored one of the most interesting parts of the Quora post, the patent that Apple filed about a manufacturing process that casts ceramic parts and silicon/rubber parts at the same time to make a single object that has both hard ceramic structure and soft rubber. That would let them unify parts like gaskets and bits that hold other bits into one single process.
So maybe even if the ceramic part of the process takes longer, they might be able to make up for lost time but cutting out steps that are further down the assembly process. To quote the patent:
"As one specific example, ceramic materials have numerous qualities that make them particularly useful for use in electronic device housings. For example, they may be highly scratch resistant, making them particularly well suited for electronic devices that are frequently subject to bumps, scrapes, and scratches, such as wearable electronic devices (e.g., smart watches, glasses and the like), mechanical watches, and other consumer products (including, but not limited to, media players, mobile computers, tablet computing devices, and so on). As a specific example, the high hardness and optical clarity of sapphire crystal (a crystalline ceramic material) may be very well suited as the cover glass for a touch-screen of a wearable electronic device. Ceramic materials may also be relatively light, making handheld or wearable electronic devices easier to carry, wear, and use. Moreover, ceramic materials may be able to achieve a high degree of surface polish making them particularly aesthetically pleasing.
However, ceramic materials typically are more difficult to form into complex geometries than plastics, and, thus, manufacturing housing components from ceramic materials can be more difficult than for other materials. Accordingly, described herein are housing components where a polymer material is co-molded with a ceramic component to form a housing component that includes ceramic and polymer material portions. (As used herein, the terms "polymer" and/or "polymer material" encompass natural and synthetic polymers, plastics, rubbers, and the like.) For example, a ceramic housing portion may be co-molded with a polymer material to form a polymer clip that is directly coupled to the ceramic material and can be used to retain the ceramic component with another housing component. As another example, a polymer material may be co-molded with a ceramic component to form a plastic coating on a portion of the ceramic component
As described herein, a polymer material forming a polymer feature may be coupled to a ceramic component by a co-molding process whereby the polymer material is molded against the ceramic component. By co-molding the polymer material directly onto the ceramic component, the polymer feature may be bonded to the ceramic material without the use of an intervening adhesive or other bonding agent between the ceramic and the polymer feature. For example, instead of separately forming the ceramic component and the polymer feature, and then adhering the polymer feature to the ceramic with glue, pressure sensitive adhesive, heat activated films, epoxy, or the like, the polymer may be molded directly against the ceramic material.
Thus, parts that include both ceramic and polymer components can be manufactured more quickly and with higher precision than would be achieved if the components had to be manufactured separately and thereafter coupled together with adhesive. In some embodiments, the polymer material is injection molded onto the ceramic component. In some embodiments, the polymer material is molded onto the ceramic component using techniques other than injection molding, such as gravity casting, or any other appropriate co-molding process. Where the present discussion refers to injection molding, it will be understood that other molding techniques may be used in such instances instead of or in addition to injection molding."
Thanks! There's also another variant that I created that we are using for our beta testing "Special Ops" team signup page: http://www.learnenough.com/special-ops
It is all custom, and the Learn Enough series is using a variation on our web book layout that we created for the parent platform http://www.softcover.io - which is what is hosting the Rails Tutorial.
No it is because the Chinese test dumped kilowatts of energy into the test item but the NASA test used only miniscule power. The guy you replied to presented the facts in a misleading way.
The difference in measure thrust is due to different test articles and testing done in different labs. The 720 mN result was from China and they dumped a ton of energy into it. The smaller 20 μN result was from NASA's testing which used far less power, so the resulting thrust measure was also smaller.
This would be amazing. I use Screenhero all the time for work, but every so often I need to help my mother with something on her computer and there is no free solution available that is better than Screenhero.
I'm just not going to pay for another subscription just to help my mother out with tech support once a quarter...
I don't know about that. What you are suggesting doesn't really fit the MO of Skunkworks where they work on advanced projects for years before revealing them. It's not like they announced stealth aircraft in the 90s just to drive up their stock price, they'd been working on it for nearly 4o years by that point and the planes were flying missions for decades.
It is possible though that though earlier attempts failed because the computational resources and the plasma dynamics modeling available at the time were not sufficient to design such a reactor.
I would guess that we have a much better understanding of plasma physics and faaaaar greater ability to model it now - that could lead to designs that can mitigate previously discovered issues with the concept.
If you are using a CI, you might as well also use something like http://www.coveralls.io to get history and statistics on your source code's test coverage.
No, the mirror is on a stick and doesn't move. When Tim is looking down at the mirror from above he can see the reflected image he wants to paint, and also the paint surface he is going to paint on. He keeps adding color until the edge of the mirror disappears at which point he knows that he got the color on the surface to match the color in real life.
I would still bet that its life will get extended. Every time that the AF has actually moved to get rid of them the Army jumps up and says, "yes! we'll take them off your hands," and suddenly the AF grudgingly extends the service life because they don't want the Army to get back into the business of having fixed wing aircraft...
That is totally up to you. You can write your book and push changes to GitHub, store the book files in your Dropbox directory, tempt fate and just store them locally, etc.
Softcover just pulls in the HTML and eBooks that are compiled from the source code, as well as the book config files, and generates the views and links.
I know you are joking a bit, but if you were really thinking about jumping into writing a novel, being able to publish nicely formatted HTML chapters as you write them for free to people is a great way to get people interested from an early stage.
He slowly published each chapter, then when he finally finished the book, he posted the ebook versions for free on his site. Eventually he added it to Amazon (and had to attach a price to it because they don't let you give away ebooks) to help people load the ebook onto their Kindle with less friction than making them download and transfer the file, he found that he was selling more copies of the book than he was giving away for free on his site.
It's exactly that model of openly sharing what you are working on with the people that are going to use or be entertained by it that we want Softcover to encourage.
