Climate Scientist: Climate Engineering Might Be the Answer To Warming

jafac Re:The Chinese could pull this off (341 comments)

Not only is it a good idea, but it may be a necessary idea (to our survival). And the idea that ppl don't want to finance it? I know, let's spend more money on weapons to invade other nations on false pretenses. That's a way better use of funds.

Climate Scientist: Climate Engineering Might Be the Answer To Warming

jafac Re:What if we overcorrect? (341 comments)

This is pretty easy to fix though. Releasing carbon is exothermic, so if we overcorrect, we just burn more fossil fuels. It's taking and sequestering carbon that takes energy input.

Obama Says He May Or May Not Let the NSA Exploit the Next Heartbleed

jafac Re:Well, yeah (134 comments)

So the question here is should the NSA put every single American SSL using business at risk for years on end to protect a single source of SIGINT?

The big question, for real, is; is there a backdoor in SE Linux?

If they were irresponsible enough to leave Heartbleed alone for 2 years, then how can we believe they haven't discovered (or inserted) compromises in other software?

Obama Says He May Or May Not Let the NSA Exploit the Next Heartbleed

jafac Re:Well, yeah (134 comments)

"spy agency's job to spy" sounds like a convenient excuse to ignore ethics. All is permissible due to expediency, and because if we don't do it, our enemies will. Guess I thought that we were better than that. If we're going to accept that we're not, then I'm wondering why exactly we came down from the trees in the first place.

Commenters To Dropbox CEO: Houston, We Have a Problem

jafac Re:Hiring A War Criminal highlights something else (446 comments)

What it really shows is that Dropbox is COMPLETELY BLIND, to the direction of international public opinion. Other US service providers are hemmoraging international accounts, because of distrust, after the Snowden fiasco. And they bring a former National Security Advisor on board, from the Administration which began ramping up abuses? It's complete ignorance. It's a middle-finger to the people they're trying to get to be their customers. These guys are totally out of touch with reality. Not only would I never use their service, if they had stock, and I owned any, I would immediately divest.

Can You Buy a License To Speed In California?

jafac all this said. . . (325 comments)

I have to say that among most of the states in which I've driven, California cops seem to be the most lenient. And by that, I mean; California has some high-limit roads... 70, 75. Actual average speeds are more like 80-85 on these highways. Some other states seem to be stuck at 55 for most roads, and their cops seem to be real assholes about driving more than 5 over. (specifically, Utah, Florida, Illinois, Ohio, where I've either been a driver or passenger in a car getting pulled over).

jafac Re:Stop Now (174 comments)

the annual cost of securing us fossil energy sources pays off for the shareholders.

Theo De Raadt's Small Rant On OpenSSL

Theo De Raadt's Small Rant On OpenSSL

jafac Re:not developed by a responsible team? (301 comments)

Considering that the first advice given to any developer looking to add cryptographic functionality to their software is: "Don't try to roll your own cryptography. Instead, try to use a well-established package written by experts." . . . pretty much tells you something.

Can the ObamaCare Enrollment Numbers Be Believed?

jafac Re:When participation is mandatory? I believe. (722 comments)

I'm employed, mostly pretty healthy, and have had no catastrophic injuries or other issues in my history, and have a pretty decent plan through my employer, but I pay through the nose for that. And; doctor choice in my county is VERY limited: they don't seem to like my provider. If I had the choice, I think I'd consider medicaid, and pocket the difference. But I am gainfully employed, so fuck me, right?

Windows 8.1 Update Released, With Improvements For Non-Touch Hardware

jafac Re:Happy that costumer pressure has an effect (294 comments)

Not only that, but I'm hearing that there is a charge for "backtracking" and installing Windows 7. One of my customers is buying a batch of devices that had Win 8 pre-installed, and the vendor was charging an extra $200 per device (for a $400 machine) to install Windows 7.

Why No Executive Order To Stop NSA Metadata Collection?

jafac Re:So in 2007 Obama... (312 comments)

Or they were blinded by the fact that McCain/Palin would have been a complete fucking train wreck for this country after 8 years of Bush/Cheney.

Obama did drop the ball on many very important issues, which he specifically campaigned on. And for that, I can't really say that I am a happy customer with my votes. But when I think about how things would have gone with President McCain, holy fucking shit we dodged a bullet.

Under Revised Quake Estimates, Dozens of Nuclear Reactors Face Problems

jafac Re:Must question the "revised" estimates (152 comments)

Wow. I really wish people would stop conflating "counts per minute" measurements of radiation exposure, with alpha and beta nucleide contamination. There's a lot of Cs137 and Sr90 contamination in the soil all over the place near Pripyat (and Fukushima), and just because you can walk through the area and get a few sieverts of decays on your skin, and no net harm, doesn't mean anyone can safely live there. Those contaminants get into dust, and you inhale it, or ingest it in your food, and they remain active inside your body for decades. It's not the same as either an x-ray, or eating a banana.

Tesla Model S Has Hidden Ethernet Port, User Runs Firefox On the 17" Screen

The Problem With Congress's Scientific Illiterates

jafac economics (509 comments)

These guys have no problem accepting the validity of an economic theory based on an "Invisible Hand" - yet when it comes to actual solid science based on actual method and process (as opposed to expensive silk suits), they start looking for conspiracy theories to explain the results.

Natalie Portman: Not Petrified (of Science)

jafac jafac writes  |  more than 3 years ago

jafac (1449) writes "Turns out, that Natalie Portman, much abused by slasdot geeks, was, herself, a Science geek, in High School, and studied Neuroscience at Harvard. Who knew?

Okay, don't answer that. I don't care."

jafac (1449) writes "As discussed in this SpaceDaily article, the video footage from the launch, earlier this week (available at www.spacex.com), of the Falcon 1 vehicle, seems to show a problem with the stage separation. I noticed this when I watched the video last night — it appears that the top of the first stage bumps the engine nozzle.

The upper stage guidance does a good job of setting the craft straight after this bump, but some odd things happen after that, including some kind of ring flying off the engine, and a wobble that gets progressively worse until the vehicle goes completely out of control. I've been fascinated by the availability of these kinds of videos more and more; but this is the first one I've seen that documents a failed launch — (Elon Musk's denials notwithstanding), and because of that, it's probably the coolest video I've seen all year."
