I think everyone's ignoring an important point. The aviation industry is extremely intolerant of accidents; especially due to manufacturing and design defects. This is a good thing for the presidents safety. The president doesn't give a crapy about fuel economy or the latest carbon fiber designs like the rest of us. They need something with a proven track record of safety.
Plus it's probably easier to add to the 747 Missle defense and reuse the radiation hardened avionics
It's not about cost. It's about design. They used to build things to last. They'll build products with improper snubbing. They know that the back emf will eventually burn out the IC and they depend on it. It lowers cost and means you buy a new electric carving knife every couple of years.
"That's how science work. You don't base your decision on the mere principle that it more or less looks kind of logical."
Newtonian physics looks kind of logical. It's completely wrong, but plenty of decisions are based on it. Despite that we know is wrong we still use it today because it's incredibly useful.
Science constantly bases decisions on kinda logical principles until those principles are proven to be wrong.
Relax dude. Now that the media is hyping vulnerabilities, this is just a way for the TV networks to make a movie about the vulnerability that stole Christmas from some poor sysadmins. They'll replay it every Christmas until the end of time. Our great great grandchildren will have to suffer through it.
This has nothing to do with a RPi. It is a common file system problem. RPi has 2 file systems.
1. Fat32 for the bootloader, proprietary firmware and kernel
2. Linux rootfs that can use many different kinds of file systems.
ext2 wasn't very good at handling unclean shutdowns. ext3/4 are a little better. fat32 is terrible.
Fortunately the fat32 partition doesn't need to be written very often, so you're good. Reads aren't dangerous.
What you really want to do is make sure your Linux kernel has an initramfs installed in the kernel image, so it can fsck and fix any file system errors if the partition wasn't cleanly unmounted.
If you're interested in home automation, then you're probably familiar with the different protocols that exist which can work either wirelessly or over the powerline. This system requires you to run 2 wires for the rs-485 to each module + power. This is not really convenient. http://wiki.openmotics.com/ind...
ZigBee and Z-wave seems to be taking over. I love open source, but I'm probably going to go the proprietary route. http://myharmony.com/products/...
You can't even compile the firmware without paying for a compiler.
"The firmware of our modules is written in Pic Basic Pro (except for the power measurement module which is written in C). Pic Basic Pro is an easy to use programming language that can be learnt very easily. We provide all source code free of charge (GPLv2 licence). The Pic Basic Pro compiler however is not for free so we ask everyone to play fair and to purchase the compiler (PBP Gold edition that supports the Microchip 18F) from www.melabs.com." - http://wiki.openmotics.com/ind...
We do not have a shortage of CS workers in this country, we have a surplus
CS workers is an ambiguous term, since a lot of CS jobs require vastly different skills. Even if your statement is based on real data, I don't think it's telling the whole story. Employment statistics are incredibly easy to spin. Not every CS worker has the skills necessary to work for Microsoft.
Not being a Canadian myself I don't have any first hand experience. The ictc article from 2013 seems to contradict your statement. http://www.ictc-ctic.ca/?p=184...
All distributed systems have similarities, but bit coin doesn't really apply very well to this. The problem with bit coins is that distributed monetary transactions have to be synchronous. The proof of work function(generating hashes) basically creates a giant global virtual clock, such that consensus can be reached. This fixes your double spending problem and also why it takes so long for a transation to go through.
This system wouldn't have to deal with all that nonsense.
I had a professor who would build an atom based PC and install an ssd. IO is usually why users perceive a system as slow.
It amazes me how hard it is to find a sub $500 laptop with ssd. Tablets and 2 in ones seem to have them, but nothing with a 15 inch screen. I was temped to buy a $200 laptop and throw a ssd in there. Not sure what I was going to do with the 500GB hd it comes with.
You have the right to use an open space reserve, but you don't have the right to do whatever you want there. You can reserve airspace for rocketry without a pilots certificate, but you have to call Oakland center first. Usually the FAA wants to arbitrate the use of the airspace for safety reasons. Most FARs are written in blood. This might seem unfair to drone operators, but regulations are changing.
Why are programmers singled out? Arguably computer automation is helping everyone. Skills are only important to have if there is value in the skill. I don't think theoretical computer scientists are any less intelligent because they never program in C or C++.
Not really. UCSB has eucalyptus running a small "cloud". That's essentially a scaled down version of AWS. HTCondor can be considered a cloud since it scales and processes can run anywhere in their network.
Of course/. has no shortage of posts about the ambiguity of the word cloud, but I prefer thd looser definition. Universities have been distributing computation for a while now on what could be described as a cloud.

Seducing a bunch of nerds with free awesome swag to entice them to show up does not constitute bribery.
What you need is corporate sponsors for free swag.
Most the people go to Google IO for the free stuff.

One thing is for sure; All the scala folks are going to try it.

That was quick. An article about ads devolved faster than anticipated. On /. We strive for excellence.
They wanted to put a 10Gb fiber connection to my house. I said fuck no. I want to notice when all my bandwidth is being used to steal all my data.
My money is on the chicken.
And those pesky helicopters keep chasing them around.

Who gave North Korea a computer? Why would they need a TLD?

Like I said ARM. Atmel licenses cores from ARM.
AMD? Arm is the real competition.

I agree. Use IaaS or PaaS instead.
