top Practical Magnetic Levitating Transmission Gear System Loses Its Teeth
This should really be looked at by those producing Diesel engines for Airplanes.
The biggest problem tinker's face when trying to put a Diesel engine on an airplane is that the Diesel has very massive "power surges" each time a cylinder fires, and a nasty power "stall" when it's compressing a cylinder. This isn't a huge deal with the other applications of Diesel engines, they just add mass to the fly-wheel and transmission and that takes care of it. In Airplanes however, the mass costs too much (in terms of airplane weight) so they try to reduce it as much as possible, however if you reduce it too much the propeller is literally torn apart by the surges and stalls. Early tests had the propeller lasting only hours when running on a 4 or 6 cylinder diesel. If there is a reduction drive on it to bring the RPMs further down they too like to self destruct with a Diesel.
If they could use a low-weight magnetic coupler to absorb the surges and stalls and provide smooth power that would solve the biggest problem putting a diesel on an airplane and would really boost that market!
top Oklahoma Botched an Execution With Untested Lethal Injection Drugs
Thanks for the reasonable response.
I am personally for the death penalty, I believe your actions have consequence and you have to pay for that consequence (a liberal nightmare). There are crimes that are so horrendous that the only consequence that can be fitting is death. Considering the crimes that these men have been convicted of I think the penalty is correct.
As for the method of going about the death penalty, I think the current system is so overly complicated that it's almost designed to fail, and when it does fail it creates a terrible situation. Going back to something like the guillotine would be a good idea, while messy it is a quick, clean kill that is hard to botch.

Interestingly when I hear that Google bought a company I don't get this reaction (yet).
I'm at that point however. I have a Nest thermostat which I love, but now that Google owns it I'm wondering what my options are. I'd love it if I could break into it and load my own firmware, or even an opensource firmware. I think the JTAG pins are exposed as pads on the main board so I should (in theory) have some access, I just have to figure out what exactly that access is...
top Russian Army Spetsnaz Units Arrested Operating In Ukraine
I think right now this situation is so complex and muddied that no-one is in the right, and no-one has all the information.
Accusations have gone back and forth like crazy but I still haven't seen any of them from either side backed up by evidence beyond "it's obvious", which, in this situation, I highly doubt.
As for these supposed Russian commandos... I really doubt they are what the report says they are. Whenever you send agents (either Spies or Commandos) into the field you strip them of anything that would identify them as spies/commandos, having ID cards for "Spetsnaz" sounds like a plant to me.
"We found the enemy's agents doing bad things so we have reason to attack!" when they are nothing more than your own agents planted to make them look like the enemy.
I also find it interesting that this bit of 'news' hasn't shown up on any even remotely neutral news sources. I frequent the BBC and have been watching their coverage of this Cluster F*** closely, and while they have agreed with USA in many of their stances and statements concerning this, they have no mention of this bit of news... makes me very suspicious of it's authenticity.
All that being said, I really think Russia is going to far and should back off, let things settle, allow the "newly independent Crimea" to exist for a while to prove it's not a Russian puppet but actually something it's people want.
top Russians Suspected of Uroburos Spy Malware
In the last, what?, ten years all of the exploits have been found by professional security researchers, spy organizations (Stuxnet), and other exploits were done by very serious experts who REALLY knew their shit.
Actually, what you are seeing is criminals taking over the exploitation of exploits, before it was hackers having fun and sending "it's my birthday" messages around, now it's serious criminals using exploits to steal serious money. These people don't advertize their finds, they use them to the fullest extent possible. When PHD's find an exploit you can be sure 90% of the time it's already known to criminals who have used it for a while.
If you wonder at the accuracy of that, just look around at how many viruses are out there and start counting the news reports for companies compromised.
top Google Apps License Forbids Forking, Promotes Google Services
Google calls out implanting "any viruses, worms, date bombs, time bombs, or other code that is specifically designed to cause the Google Applications to cease operating" as being banned in approved devices.
It's both interesting and very sad that this has to be spelled out in a license agreement, makes me think that they've run into OEMs purposefully building 'bombs' to keep people buying new phones.
top Atlanta Gambled With Winter Storm and Lost
Southern WI got hit with 2 inches of "Wintery Mix" yesterday, along with blowing/drifting snow from the 2-3ft of it already on the ground (winds were around 20mph).
However, this is a state of people who have experienced the above a couple times a month during the winter season. We know how to drive and handle the conditions, and WI has really amazing road crews that work very Very hard to keep the roads drivable and are very well equipped for what they are doing. I wouldn't want to be in your shoes, that same "wintery mix" with millions of people inexperienced in driving in those conditions and road crews who have rarely if ever faced such a mess and are ill equipped to make much of it. I am not patronizing you in any way, those conditions are legitimately terrible.
Were I down in that area during the storm, I'd likely have taken the day off or worked from home. If I had been at work when that hit and told to go home, I'd probably have found the closest friend to work and crashed their couch instead of trying the full trip home.
Then again I'm usually driving with a blanket or sleeping bag in the car in case I get stranded in the snow. Northern winters are not something to take lightly. It doesn't have to be snowing for there to be white-out conditions, all we need is snow already on the ground and a good wind. We also get a decent amount of real cold around here, while this year is especially bad, it's a rare year that we don't go down to -20f for a few days or a week. Most people here who do any driving outside the cities/towns will have gear in the car to survive being stranded in the snow overnight in -10 to -20 conditions, it's part of living here.
top Examining the User-Reported Issues With Upgrading From GCC 4.7 To 4.8
I wonder how many crashes/bugs in software are actually the result of bugs in the compiler?
I think I've seen two in twenty years. So they happen, but not often, and usually only when they run into very unusual code.
You see them more often in the Embedded world than on full computers. A big one I ran into recently was with Freescale 68HC12, an ancient processor and compiler. It would randomly decide if incrementing or decrementing (var++; or var--;) would be done as integer increment/decrement (add/subtract 1) or pointer increment/decrement (add/subtract 2). We had a lot of interesting bugs where it would randomly decide that a for loop would do pointer math instead of integer math and we'd skip half the work.
This was very recent, and with latest patches (for some definition of
latest... they were concentrating on their new eclipse based IDE with it's GCC compiler so this one wasn't being worked on).
top Building an Open Source Nest
I am ready to look into that, I have a nest (1st gen) and experience and tools in embedded development, looking at the
mainboard (reverse side) for the nest there are plenty of touchpoints and even a set of contacts, how much you want to bet the JTAG interface for the Microprocessor is exposed letting someone (like me) install my own software?
Right now I'm looking around to see if anyone else has started this effort, no takers thus far but maybe that's just my search-fu being weak.

top Paging Dr. MacGyver: Maker Movement Comes To Medical Gear
A wiring harness may just be easier to build yourself, there are places you can get the color coded wires and the wrap for bundling them together, and there are likely plenty of sources for wiring diagrams, worst case you can tear apart your old harness to make a diagram of your own. (speaking from the standpoint of someone who has looked into this for my '64 p1800)
Making other car parts is a different issue entirely, at least for the engine... most likely one that will stay in the realm of casting and machining instead of 3D printing.
An engine part often has very very tight tolerances, down to 1/1000th of an inch for mounting surfaces and alignments, something I don't see 3D printing replicating anytime soon, then to add to the fun engine parts have to hold up under stress from the combustion process, lots of heat and vibration.
Now, that's not to say it will never happen, there may be a 3D printer capable of laying down metal with strength comparable to cast or forged counterparts, with an accuracy capable of a mirror finish, but I'm not expecting it anytime soon or for a price that's less than the value of the entire car.
However, if you want to print cosmetic components of a car (rear-view mirror mountings, gauge faces, handles, etc) that is very likely possible now.
top First Hard Evidence for the Process of Cat Domestication
Can you imagine a pack of modern house cat's successfully patrolling farmland?
Easily, because it's a common sight out in farmland. Maybe not so much in the big corporate farms but smaller family farms will usually have anywhere from a dozen to fifty or so cats running around the farm taking care of rats, mice, keeping 'coons and foxes at bay, etc. In fact, two of the cats I now have indoors, were born to barn cats and taken in while still kittens.
top Thieves Who Stole Cobalt-60 Will Soon Be Dead
America was founded on the ideals of religious freedom by people who were predominantly Christians, this led to Christianity being the 'popular' religion of this country, but it is in no way the only religion.
Unfortunately that has led to as many problems for Christians as it has solved. Since Christianity is the 'popular' religion many people say they are a Christian when they really aren't (i.e. 'Sunday Christians'). This has led to many incidents where people who claim to be Christians do something terrible which then gets blamed on Christianity as a whole instead of the individual, this is especially disheartening when their actions go against Jesus' teachings.
Think of it like sports fans who only follow the team that is currently winning, and as soon as another team comes out on top they switch over and are running around with a whole new set of colors and jerseys. Meanwhile they are starting fights and causing disturbances all of which get blamed on the 'fans' of the team whose jersey they happen to be wearing at that time.
As for the original sentiment, I agree that as 'punishment' death is far too excessive for assault and armed robbery, however as 'Karma' it works just fine.
top Dead Drops P2P File Sharing Spreads Around Globe
Something like a slightly modified Raspberry Pi with a custom OS that simply pulls all the content and saves it as a drive image that can be scanned and parsed, or maybe just grabs specific files (just image files or pdf files) and ignores all other files. In the end delivering it to another USB drive or an SD card in such a way that it's safe to open from your computer...
(optionally) uploads new content to the USB drive.
This sounds like a fun project, I'll have to start playing around with it.

top Time Reporter "Can't Wait" To Justify Drone Strike On Julian Assange
Leviticus is primarily a book with how the Levites are supposed to live. The Levites are one of the twelve tribes who's primary purpose (set out in Leviticus but started from leaving Egypt) is to be the religious administrators within the Jewish religion (priests, temple servants, etc.).
Why does this matter? Every time some idiot pulls up a rule from the book of Leviticus and tries to point out how Christians are hypocrites because they aren't following that rule are being the idiots, those rules are for the priests of Judaism, not for the common Christian.
Trying to apply rules from Leviticus to modern Christians is like trying to apply proper care of your horse to driving an electric hybrid.

top Researchers Crack iOS Mobile Hotspot Passwords In Less Than a Minute
So, someone else might be able to jump onto your phone data when you are tethering... however to do so they need to lug around a big computer tower with a bunch of GPUs plugged in, and only if you use the default password.
This is very much a non-story. Most people using tethering will have it enabled when they need it then turn it off (otherwise major battery drain), so they might be able to use your internet for a little bit but then they'll be left with nothing. And it's really
easy to change the default password, on the screen to enable mobile hotspot on your phone the password is displayed, tapping on it gives you the keyboard to change it. This was the way it worked from the beginning of IOS tethering. really
With changing the password being so easy, how many people who use tethering would leave it at the default? Most people I know would change it just to make it more personal and memorable.

top Will PCIe Flash Become Common In Laptops, Desktops?
Graphics cards can support only X number of pixels/polygons/etc, and I've seen more than once graphics cards with multiple outputs that can drive either one really big display or two smaller displays. This is nothing new, nothing surprising. I've even run into it several times in my own computer history, a graphics card that can support amazing resolution on one monitor, but when driving two it drops down to mediocre.
As for driving graphics cards through Thunderbolt or Thunderbolt 2, I'd agree that the speed doesn't match current graphics power. However, I also doubt such is necessary for 99.99999% of users. I do think that the bandwidth would be enough to drive non-graphically intensive display, (eg non-3D games) still allowing the displays to be useful for everything but the graphically crazed gamer, who has never been a Mac user to begin with.

top Linus Torvalds Promises Profanity Over Linux 3.10-rc5
I often find that option 2 leads either to collapse or option 3.
When people are doing their own thing in a passive-aggressive fashion they can easily get into a situation where they are undermining the end goal, and if it continues it will cause the project to fail. If they don't respond to option 1 and they start using option 2, then the leadership is usually left with option 3 or simply firing them in order to keep the project successful.
