If that's true, then you could have extremely efficient flight at Mach 20.
Glide ratio != efficiency per passenger mile.
I don't think there was anything efficient about the HTV. It carried 0 passengers and the heat literally melted it's own skin off. Building a fast missile with a good glide ratio has very little to do with fuel efficiency of a passenger plane.
Is this maneuver easier or harder to do inside the atmosphere of Mars, as compared to Earth? It sounds like a possible plan for return trips from Mars, if the rocket is re-usable.
That's actually hilarious. While I applaud that they display the error code, it is funny that it requires a convoluted "special knock" to make it display the error code. How about just displaying the code right away? Or a button labeled "display error message?" If someone built a car that sang the error by Morse code after you opened the front passenger door 3 times would we call this good design?
I think I was in my teens before I learned it wasn't his actual birthday. Maybe even later. Maybe I should be embarrassed by that fact or something. Nobody ever corrected me, since it wasn't really a discussion topic, so I think I only discovered it through some unrelated reading. Every sermon, song, etc. said it was his birthday. I had no reason to question it since it wasn't of any theological importance. I think the same thing happens with the "3 wise men" as well. Why the heck do they put them in nativity scenes?
I just heard this on a secular radio station a few days ago: http://www.lyricsmode.com/lyrics/c/christmas_songs/born_on_christmas_day.html
It's funny, I can't think of ever meeting a person who doesn't understand that it's a celebration, not an anniversary.
Have you asked, or are you just assuming they understand it the same way as you did? Maybe it was common belief 20 years ago but not today? Or maybe children believe that but figure it out later? Or maybe I'm just dumb.
I'm sure they already have a 3/8" socket set on board, so this was just a test.
Actually they didn't. The Americans looked everywhere: they asked the Russians, Canadians, Brazilians, and Japanese, but all they could find were 9.5mm!
Didn't the rouble lose like a million percent of its value...but they also don't want to alienate the Russians by raising their prices to compensate for the currency crash
Economically speaking, this would mean that valve is selling games at 1 millionth of the usual price, but still profiting off them. Profiting so much, that they are willing to make custom software changes rather than just change the price. That's surprising math to me. Sometimes I wonder why companies, especially companies selling digital goods, don't just set the price in one particular currency then let it somewhat auto-fluctuate in the other currencies according to the market. Wouldn't that be simpler for them?
Politically speaking, Russia's currency lost value because they invaded a nearby nation and they are under sanctions. It is interesting that Valve is willing to go through effort to continue to offer them games at a price they can afford.
Excellent questions. There are a few reasons, but they are indirect.
Why would they care if anyone uses
1) Because Azure will be the default place to deploy
2) Because
3) Because Windows phone and Windows 8 and the Windows store will be the default place to deploy those apps, which makes them money.
Also, note that there have been free and cross-platform imlpementations of
Isn't this more of an indication that they are abandoning
Open source != abandonware. And open source != free to maintain. Red Hat has not abandoned Linux, and pays quite a lot to improve and maintain it. Microsoft is moving toward the same model.
FUD.
What patents? The stuff they are open sourcing is dependent on DirectX or even Windows. It runs on Linux and Mac.
What has changed is that open-source is no longer a threat to Microsoft. It was a threat when Windows competed against Linux for the desktop and for the server. But today, Microsoft doesn't care about Windows and has re-invented itself: Microsoft lays its hopes on Azure.
All this open-sourcing of
Microsoft's new competitors are OpenStack, Amazon, and other cloud service providers. They will compete with those providers by trying to have the cloud platform that supports the most tools and the easiest process to get stuff into the cloud.
Facebook is doing some interesting research. Is it even possible to determine, from a picture, if someone is drunk? Do you start with face recognition algorithms, and look at the face? Can the algorithm learn body language? I am skeptical on this.
Fashioning such a tool is largely about building image recognition technology that can distinguish between your drunken self and your sober self, and using a red-hot form of artificial intelligence called “deep learning”—a technology bootstrapped by LeCun and other academics—Facebook has already reached a point where it can identify your face and your friends’ faces in the photos you post to its social network, letting you more easily tag them with the right names.
Identifying one's face is not barely even AI any more. The fingerprint is based on the distance between the facial features. Yes, neural networks and things are good at finding those features, so AI is involved to some degree. Identifying some vague concept like drunkenness based on a facial recognition algorithm seems like a big step. I'll be impressed if they can do this with any reliability. I bet you could do better looking at the GPS coordinates of the picture, proximity to bars, the people in the picture, and the time of day. Maybe that is more like what they are doing, than actually judging the image itself.
P.S. This is supposed to be a tech blog. How sad is it that a story about deep learning AI yields nothing but a series of jokes about drunkenness?
Sounds like the HP and IBM law suits over printer cartridge lock-in.
This is *exactly* the kind of thing that the DMCA was made to prevent! Tape is a circumvention device and should be banned! (Since there was recently an article here about how the DMCA is being abused, so I'm itching for them to issue a DMCA takedown against this article so I can add it to the list of reasons to repeal the DMCA).
By 2017, they anticipate 1.95 customers.
Who are the customers of this? I am skeptical of the business model for 3D printing as a service.
There are 2 kinds of people who want to 3D print:
- Makers
- Gimmick lovers
The makers won't use this service. 3 years ago every hackerspace had a 3D printer, and it was a cool reason to join up. Now, the makers just buy their own printer. The cost has gone down, and designing a 3D object is an iterative interactive process.
The gimmick lovers could use the service. There are two types of gimmicks:
- Stock gimmicks that are all the same
- Custom gimmicks
If there is significant demand for a stock gimmick, then it is cheaper and faster to mass produce the item and sell it. This is how we have done it for decades. Popular items on Thingiverse and are now sold on Amazon.
That leaves custom gimmicks and low-demand stock items for 3D printing. Does the royal mail have a system for customizing gimmicks? If not, then the pool grows yet smaller. I don't know if that customer base is big enough to be profitable. Maybe someone who wants a custom or rare gimmick can find a friend with a 3D printer. That's how it was with 2D printing back in the 80s. You always had a friend with a computer and a color dot-matrix printer, and they could make those "Happy Birthday" banners for you. I suspect that might be the way this really works.
How many places offer CNC routing as a service? That seems like the most equivalent thing to 3D printing. It has been around for decades, but I don't know of the post-office offering that service.
Those who have decided MS is eternally evil will never accept
Their new hope is Azure. All this open-sourcing of
Happiness is twin floppies.
