SSD Annual Failure Rates Around 1.5%, HDDs About 5%
I manage a small cluster of 8 machines with 24 OCZ vertex 3s a piece.
My own experience was that all failures for these were based on bad firmware, either on the raid controller or on the disk themselves. We had massive failures for a while there... 1 a week, 2 a week...
then we upgraded the firmwares on both and it all just went away. We've lost 1 disk in 2 years since.
Newb-Friendly Linux Flavor For LAMP Server?
I haven't verified that it has all the versions that you want, but I've used SME server on and off over the years for such things. It's quite newb friendly, and not completely command line. There are quite a few other options as well.
Costly SSDs Worth It, Users Say
I moved a small 4TB database from 24x 256G 15k SAS drives to 24x 240G OCZ Vertex 3 SATA3 drives. I ran a few queries on the old and the new. same data, same parameters, same amount of data pulled. Both were hooked up via PCIe 8x slots.
the SSD crushed the SAS. Not just a mere 2x or 3x crushing. A _FIFTEEN TIMES FASTER_ crushing. This was pulling about a million rows out. 12 seconds (SSD) vs 189 seconds (spindles)
Cost difference? under $50 per drive more expensive for SSD. I think our actual rate was around $10 per drive more. However, the system as a whole (array+drives+computer) was $12k less. No contest... for our particular application, SSD hands down makes it actually work.
we'll be moving the larger database (same data, same function) to SSD as soon as we can.
Roundabout Revolution Sweeping US
In the last decade, the area (actually 3 towns) put in roundabouts all over. One of them put them in in quite a few places.
I personally don't have a problem with them. They make sense to me. However, there are a lot of people who don't understand the rules of them. They think they can go whenever they like.
I find this particularly bad on two lane roundabouts, of which there are two within a couple miles of my house. One of these I go through every day. It seems that folks have not realized that both lanes of the roundabout have right of way. I have nearly been t-boned in the roundabout because of this.
Driving, yet one more thing that we need to have a "you must be this smart to do it" metric.
Stars Remain In Their Usual Places; People Panic
even if you follow astrology a little (I do, for amusement), this is f-ing retarded.
Not Transparent Aluminum, But Conductive Plastic
the question is, transparent to what, really. If it's opaque to everything _except_ human-visible light, that's still a pile of the spectrum and of energy.
Cambered Tires Can Improve Fuel Economy
Apparently, BMWs and Minis (and probably other sport-ish cars) are negative cambered because it helps with handling. I found this out replacing the tires on my mini... the ones that I burned through in 1.5 years because I drive it like a sport-ish car ;)
Facebook Goes After Greasemonkey Script Developer
Sorry, you distributed content, we can throw it in the trash if we like
Bullet-Proof Sheets of Carbon Nanotubes
My guess is it's more about the weight. carbon nanotubes are about 1/7th the density.
Encryption? What Encryption?
I've often wondered why when you are setting up your user account on a box, and it gets to the part with setting up email, it didn't give you a chance to generate or import public/private keys right there and them upload the public to a server. Particularly on linux boxes, this seems like a completely feasible option.
One might also envision having a secret key storage mechanism, either by local external media or via remote storage where it could go look.
Prehistoric Gene Reawakened To Battle HIV
go read the abstract. I understood that and was thinking the same thing. also along with an obligatory holy shit that's awesome.
Electric Company Wants Monthly Fee For Solar Users
I can agree with this logic. I do wonder when they will start charging a "feed your extra power back into the grid" fee will begin and any number of other fees that might arise out of this.
Shrinking Budgets Tie Hands of Security Pros
I have seen a lot of places that insist on buying a "solution" to the problem, when in fact the solution barely touches the problem. it works around a lot of things, but never really hits right on it. So you've spent a lot of money on something that doesn't really do the job of a person in that role.
The funny part about security is that for all it's sex appeal, real security is actually pretty boring. Oh the hotness of configuration management using tools that are already available on the windows or linux box. How your endorphins get moving at the sight of a patched on patch day. Or the sheer porn of being able to look at your log files and know that all is good.
We all love honeypots and whatnot, but those things need to come well after patching, configuration management, removing/pruning user administrative permissions, and controlling which software you allow, and strong authentication enforcement. This doesn't have to cost a lot of money.
Analysis Says Planes Might Be Greener Than Trains
Cars emitted more than any other form of transport with the notable exception of off-peak buses, which often carry few passengers. Passengers on the Boston light rail, an electric commuter train, were found to emit as much or marginally more than those on mid-size and large aircraft. This is because 82 per cent of electricity in Massachusetts is generated by burning fossil fuels.
So, if you are burning lots of fossil fuels to run your light rail, then yes, it is like a coal fired plane :)
TFA also talks about building trains into major population centers to eliminate the need for infrastructure for cars to _get_ to the train. It also talks about how trains have a different power problem than air/car/bus, and one that, honestly, I think we're a lot closer to solving.
Daydreaming Is Really Complex Problem-Solving
Always felt like I was more alive in a daydream then I was doing grunt work.
I like my mind active or I grow bored. i'm sure much of slashdot is like this. Found that I daydreamed a lot and had a hard time focusing on grunt work
No More D&D PDFs, Wizards of the Coast Sues 8 File Sharers
The more starsystems will slip through your fingers.
and I was going to buy about $300 of 1e pdfs. oh well, guess I'll torrent because I CAN'T GET THEM ANYWHERE ELSE NOW.
Strange Globs Could Signal Water On Mars
would the perchlorate they suspect in there keep it liquid at the (what I believe to be is) low atmospheric pressure on Mars? Seriously don't know :)
Best FOSS Active Directory Alternative?
I can second SME server. I've been using it for this role since it was E-Smith many years ago. It's a fantastic little distro for a lot of different reasons. Definitely good stuff.
Scientists Hack Cellphone To Detect Diseases
The irony of this is that as this article was being posted, I was talking about how close the iPhone was to a tricorder on a plane with the guy next to me. I checked slashdot when I got off the plane and LOLed on the spot in the airport. Weird coincidence.
Open Source Program Reveals Diebold Bug
In testing. You need to be able to verify the testing mechanism. Open Source will win there because of the ability to view and modify the code. Just verify that you are testing with the same stuff that you reviewed.
