Crowd-Sourced Experiment To Map All Human Skills
They need to fork Wikipedia, and add some directed tree flags to it. Skill META can be considered to belong to multiple parent categories, and has multiple meanings because of the vagaries of language META.
Any attempt to shoe-horn this into a tree is going to fail. Oh... and their search function is dead.
There's No Such Thing As a General-Purpose Processor
Yes, you can use almost 100% of the silicon, if you use a BitGrid to process information instead of Von Neuman architectures.

Changing clocks twice a year is nuts, nuke this insanity from high orbit.
A Mysterious Piece of Russian Space Junk Does Maneuvers
The recurrent weakness in US military thinking (and procuring) is that small numbers of fancy, high tech stuff can beat large numbers of low tech things.
This is also the same reason the Nazis tanks lost their battle against he Russians... most of them failed due to mechanical problems, only a smaller amount of them were destroyed in combat. One might almost think that all those scientists from Project Paperclip infected us with the need to do fancy things.
Utilities Should Worry; Rooftop Solar Could Soon Cut Their Profit
So you are arguing against widely distributed small generators on that basis? They provide LOCALIZATION OF PRODUCTION by their very nature, so I suggest you be a bit more honest about your reason for objecting to them.
As nuclear is far more reliable
If there were thousands of little generating plants, we wouldn't need a big heavy duty grid... but solar is not a generating plant. It is a sometimes available source of energy which perturbs the balance of the grid over the time frame of seconds.
The Grid is a system designed to reliably deliver power from a set of fairly reliable constant power sources. Those sources were designed to go online and stay at design load for many months at a crack, then have a scheduled maintenance outage. and then do it again. There are stresses associated with each transition, which are cumulative, and result in finite lifespans for things like generator shafts.
Yes... a generator shaft is a big dumb piece of steel... until you start to think about it and dig deeper. It was probably cast in a spinning mold with a vacuum applied to cause any defects to be located in the center of the shaft. Those defects are then bored out, and thus you have a nice, strong, reliable piece of steel good for 5 decades of service, with a huge margin of safety. This huge margin considered 12 outages and/or unit trips per year, a safety factor of probably 20 for good measure, and an outrageous 50 year service life.
Since the 1950s... plants now cycle far more often thanks to big cheap nukes.... cutting that margin way back. Now you want to cycle them every time a cloud passes through the neighborhood of a large solar installation? They won't last 5 years at that rate.
The stresses on the whole grid from crappy politically special flowers will eventually collapse the grid unless some heavy, HEAVY upgrades are done... which just ain't gonna happen.
Solar/Wind is going to kill the grid... just wait and see.

Who is going to replicate these experiments? It's not science until someone can do it, and then someone else... and then someone else...
Putin To Discuss Plans For Disconnecting Russia From the Internet
The Republic of Texas has its own power grid. I've heard rumors in the distance past that they have the ability to isolate their phone lines. I see no reason to doubt that they kept up with the times when it comes to the Internet.
Of course... it's just a rumor.
U2 and Apple Collaborate On 'Non-Piratable, Interactive Format For Music'
How fittin' it is that this tail comes on talk like a pirate day. The lubber has no idea what the crew has ready, once we host the jolly roger.
Mystery Signal Could Be Dark Matter Hint In ISS Detector
How the heck did ISIS make it up into orbit to attack the space station? You can't trust the Russkies, can you?
Next thing you know ISIS will be on the moon, and we'll have to bomb them. ;-)
The MOOC Revolution That Wasn't
I completed the Stanford AI course, recently did a course in communications from the University of Amsterdam. In both cases, time management was a problem for me, I simply had other things to do, and drifted away... catching back up in the nick of time. Trying to fit distance learning into the regular schedule of campus life seems to be the problem here... it is definitely not the depth of material that is any kind of a stopper.
I think that guided deep dives into topics we would otherwise not understand, is going to be how we keep accumulating knowledge as a species in the future. Deep diving takes time, and unlike the real diving... it doesn't all have to happen in one shot.
On a side note... it is worth at least $20 to me... possibly much more... if someone can give me the deep dive that results in me understanding the Higgs field, and the Higgs particle. A true understanding... not some vague notion of mexican hats and potential.
Researcher Fired At NSF After Government Questions Her Role As 1980s Activist
It is utterly offensive to me that the State Department gets to decide who and what groups are "terrorists". Free Association is one of the key tenants of a functioning Democracy.
I find the associations between lobbyists and government officials to be a clear and present danger to our country... but what can I do about it?
New Nigerian ID Card Includes Prepay MasterCard Wallet
You do mean 616, don't you? Its bad enough when governments break their promise to pay money for currency.. the ability to take all of your money and your identity in one fell swoop seem to be the ultimate tool for sorting out Serfs and Lords.
Operating Systems Still Matter In a Containerized World
Instead of trying to harden an OS, why not use a system designed to be secure from the start, one that supports multilevel security. The technology was created in response to data processing demands during the Viet Nam conflict, and perfected during the 70s and 80s.
Ask Slashdot: How Dead Is Antivirus, Exactly?
The root cause is that the security model of Unix that everyone copied isn't compatible with the modern world. The OS never asks what resources you want to allow a given program to access, instead it ass-u-me-s that it should have full run of everything, and just trusts the program to do the right thing.
So antivirus programs were invented to serve as a "no-fly-list" type system.... only programs on the list are stopped. This worked well until methods for changing the signature of programs got up to speed. Imagine a terrorist being able to make up a name before trying to buy/board a flight... this is where we are now.
Until we get the OS to ask what resources a program should be allowed... things will keep getting worse.
The Billion-Dollar Website
Because 10% of a working system can't be measured. Even a 100% completed to spec system is worthless until it has actually been used for a while... when it will prove to need about 100% more work.
Most software projects fail, unlike construction, etc... engineering can't be applied.
Leaked Docs Show Spyware Used To Snoop On US Computers

Long-Wave Radar Can Take the Stealth From Stealth Technology
The lowest frequency you could use to track a target should be on the order of one that results in the target being 1/2 wavelength. Given the F35 is 16 meters long, that works out to about 10 Mhz. I highly doubt there is an effective way to absorb/deflect a radar pulse at such a low frequency (and depth of penetration) in an aircraft.
I've known this since the 1980s... I highly doubt that I'm in any way unique. I expect there are a number of spread spectrum 30-50 Mhz radars out there, just for catching "stealth" targets.
How long ago did you last assemble a computer?
I designed and built my first embedded microprocessor project (for remote metering) using an 8088 and a 8284 clock generator chip, with some EPROM and static RAM back in the early 1980s.... I've been working on computers ever since.

Some good discussion about cabsec
I was glad that there was some fruitful discussion about CApability Based SECurity (cabsec). I learned some things, and hopefully passed on some lessons as well. Thanks to all who joined in the comments in response to mine.
Pushing the iceberg
Million Bit CPU?
Non Von-Neuman architectures are tough to wrap your mind around, but it can be worth it. I hope to find a few other people who can see the power of this idea, and bring it to realization.
Intellectual Property is EVIL
We're slipping a long way towards corporate ownership of ideas, and the public discourse. This is one of the many embodyments of the forces of darkness, and should be fought tooth and nail.
I'm not depressed any more, now I'm just amused.
They've killed off the only hope of a mass distribution system for music which they could monitor or control (or... gasp... make some money off of), and in so doing killed off viral free advertising.
They're clueless morons, and... as it says about Earth in the Hitchhikers Guide to the Galaxy... Mostly Harmless
Soooo... slashdot does Journals now
I just finished reading "Hackers" by Steven Levy, and now I'm depressed... it seems that the true hackers are all gone, and there's noplace to find them anymore... maybe Slashdot is it, and I just don't recognize it... hard to be sure.
Well, there it is... a comment, to be preserved forever in the machine.
PS... you can edit them after the fact, a nice feature.
