  1. Re:Free? on Obama Proposes 2 Years of Free Community College · · Score: 1

    A lot of the high school classes are dumbed down enough that they really don't prepare students for college level courses.

    Interesting. This must vary wildly based on the high school and the community college involved. I live in Maryland and found the opposite to be the case.

    When I was in community college I was afraid that what you just described would happen to me, so I took Calculus 1 in community college even though I already had it in high school. I then realized that the high school course went further than the community college course and was more rigorous.

  2. Re:no one cares about your data as much as you do on Study: 15 Per Cent of Business Cloud Users Have Been Hacked · · Score: 1

    I am surprised people were naive to think "cloud" vendors could be trusted with their data.

    You are assuming that the cloud vendors are at fault, but the article doesn't really pin the blame on anyone. Everyone's knee-jerk reaction is to blame the vendor, but who really is at fault here?

    The article talks about business users sharing files inappropriately, like opening them up publicly or storing files like source code on the cloud which is often in violation of the policies. It says that 15% of business users' accounts have been compromised, but it doesn't say why or how. So we don't know if the cloud vendor was the one at fault, or if it was the users' fault. Looking at the top cloud apps they are listing, they are things like Google Drive, Facebook, and YouTube. So far I don't think there have been any major compromises to these apps, so that indicates that the problem is more likely on the users' side. I wonder if the real report says that.

  6. Re:Laywood on Hands On With MakerBot's 3D-Printed Wood · · Score: 2

    I have a jammed extruder on my Makerbot Replicator as a result of printing in laywoo-d3. For whatever reason it stopped extruding while I wasn't watching, and when I came back I found it permanently jammed. No amount of unloading or loading will fix it. At this point I will have to resort to some of the more difficult measures such as running acetone through the extruder, or drilling it out, or something like that. The trouble is that I don't know what resin is in the laywoo-d3 so I'm not sure if acetone will work in this case or if I need something else.

    I am not sure if my experience is typical or not. While everyone says that Makerbot's announcement is not a big deal, it really is important because it means they have tested and endorse the product. If you just run experimental filaments through your printer you do so at your own risk.

    Also note that the failure here might not be the filament at all. Printers need to be able to detect extruder failures and stop the print before the extruder becomes permanently stuck. I think this is coming in newer models, as it is certainly on the professional products.

    Lastly: The stuff really doesn't look much like wood. I tried the "cherry" color and it looks more like weak reddish-brown plastic. You can run scripts that adjust the temperature to get a gradient effect, but it just isn't very realistic. The material is very soft and I don't recommend it for most purposes.

    Oh daaaammmmn boy you got me! That buuuurrns! Sheesh, I hope you don't respond like that IRL. As a glider pilot, I am well aware of the meaning of glide ratio. So, skipping the ad-hominem attack and moving on to discussion:

    Yes, glide ratio is very important. But the glide ratio of the HTV is not comparable to the glide ratio of a passenger plane. It held essentially no cargo and unfortunately, these things don't scale linearly. :-( Suppose we could make something with a glide ratio of 1000:1, that could carry 10 lbs. Physics does not permit us to scale that technology to carry 10,000 lbs and retain the efficiency.

    A sillier example: a bullet probably has a good L/D too, but we would not point to a bullet and draw the conclusion that passenger jets could get similar efficiencies.

    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.

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?

    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 .NET if it's free and cross-platform?

    1) Because Azure will be the default place to deploy .NET servers, which makes them money.
    2) Because .NET developers will tend to use Visual Studio, which makes them money.
    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 .NET for >10 years. It has done very little to dilute Microsoft's business.

    Isn't this more of an indication that they are abandoning .NET so they don't have to keep paying to maintain it?/quote.

    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 .NET is to entice people to use .NET and thus use Windows Azure. By eliminating the stigma of being closed and proprietary, they eliminate the #1 objection to using .NET. This openness goes both ways: not only is .NET opening, but Azure is supporting other stacks: node and LAMP for example. They don't care what tools you use anymore, they just want your hosting business.

    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.

  18. Is this technologically feasible? on Facebook Offers Solution To End Drunken Posts · · Score: 1

    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?

    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.

    Very wise question. Is it because the amendments are made by committees?

    IMHO, this is one of the problems with the US system. The constitution grants the houses the ability to govern themselves. So while a bill requires a simple majority to pass, there are lots of other votes that must happen before the bill can even be voted upon. There are rules static when a bill can be introduced, how amendments are added, how it gets out of committee, and how it comes to the floor for vote. So in the end, a senator/representation can't just propose X and bring it up for a vote. At that point, is it really democracy any longer?
