Underground Experiment Confirms Fusion Powers the Sun

mark_osmd Re:Thought that was obvious... ? (141 comments)

Another surprising fact, the Sun's core is so dense (150 g/cc) that a metric ton of core only needs the volume of a cube 19cm per side to occupy.

Declassified Papers Hint US Uranium May Have Ended Up In Israeli Arms

mark_osmd Re:Good for them. (165 comments)

That's a rumor of a strategy, usually quoted from unidentified third parties or as personal opinions of military historians. I don't know of any official Israeli government document or statement that there's such a doctrine. It would be hard for them to since there's no official admission by Israel that they possess nuclear weapons. When looked up in wikipedia it's described as "...the name that some military analysts have given to Israel's hypothetical deterrence strategy of massive retaliation with nuclear weapons as a "last resort" against nations whose military attacks threaten its existence" hardly equivalent to nuking "every major European city" which implies those cities are in nations not attacking Israel.

Firefox Was the Most Attacked & Exploited Browser At Pwn2own 2014

mark_osmd Re:Firefox is the most unstable program in common (207 comments)

I think the 'crashy' people are installing huge numbers of questionable plugins. I have good luck with Firefox but only install a few well selected plugins (noscript, better privacy, adblock, flash block, littlefox, and self destructing cookies). Because many of those plugins block crud like flash ads I get even better stability.

Forests Around Chernobyl Aren't Decaying Properly

mark_osmd Solution... (167 comments)

Go to other areas of Europe and Russia that have normal forest breakdown, grab some soil and dead leaves and spread them in select locations around Chernobyl. If the fungi and mold was damaged back when the radiation was really high it can be reseeded now that it's lower

The Far Future of Our Solar System

mark_osmd Re:Hawking radiation (122 comments)

That's true right now, the 3K background is higher than the tiny temperature of the black holes. But the background temperature will get lower and lower as the universe expands, eventually it would get lower than the hawking temperature of even the largest black holes. At that point all black holes will be shrinking.

Thanks to Neutrino Detector, We Might Get a Good Look At the Next Supernova

mark_osmd Detecting the neutrino ramp up to explosion (85 comments)

I'd be more interested in someone making a neutrino detector sensitive enough to detect the silicon burning stage just before the supernova explodes. That would give a day of warning.

The STEM Crisis Is a Myth

mark_osmd Re:What about diversity (284 comments)

Mostly that's because these companies have the Government for their main customer. That's the only explanation I can come up with for the diversity training I see at some companies. I have to assume the feds have some requirement that they only deal with companies with a certain set of diversity policies. You take your annual training and mostly it's business as usual. Companies that mostly sell to plain old private companies or individuals probably ignore the diversity stuff.

Nuclear Arms Cuts, Supported By 56% of Americans, Would Make the World Safer

mark_osmd Re:Biggest mistake going (615 comments)

A lot of people don't realize that the average age of US nuclear weapons is a lot higher than some other powers. All are older than 20 years and the last new U.S. design was from 1991. So an unknown and likely significant fraction of our nukes would probably dud if used. We at least need to rotate old nukes to make new ones into the arsenal so the ones we have are at least reliable. Plus some work needs to be going on to keep the skill pool of the nuclear engineers up, the engineers with experience of actually building a weapon are getting pretty up there in age and lots have retired.

Missile Defense's Real Enemy: Math

mark_osmd Re:this is a stupid example (589 comments)

Smart interceptors (like Iron Dome, today) are always going to be way more expensive (like $90k) than the incoming warhead (Palestinian Shahab, like $300).

One thing the Israeli's do is only expend an Iron Dome if and only if the incoming Kasam or Shahab is heading to a populated area. When the adversary is going as cheap as these Hamas rockets are, they have pretty poor accuracy and frequently land in empty areas.

Oracle Knew of Latest Java 0-Day Security Hole In August

mark_osmd The hole is only relevant to the Java plugin? (265 comments)

I was reading that the vulnerability is not in general standalone Java but only in the Java plugin in your browser, that is, you can secure from the issue by disabling the Java plugin in your web browsers but it's not that big of a risk to a standalone Java app. Is that true?

Study: the Universe Has Almost Stopped Making New Stars

mark_osmd Re:Red Dwarfs (228 comments)

Another interesting point about red dwarfs, along with the extremely long life time they have (ten trillions years), is that the universe locks away some material as brown dwarf pairs. In the extreme future after star formation is all done, a few of these pairs will spiral together from gravitational radiation forming new red dwarf stars if the total mass of the two objects is more than the minimum red dwarf mass.

U.S. Election Day In Progress: What's Been Your Experience?

mark_osmd Re:SC - 1 1/2 hour wait. not too bad (821 comments)

The deal here in Maryland that makes the voting lines slow is the ballots are getting a bit long. The one here in 2012 had 30 selections to make. I got in line at 3:30pm and was done at 4:13 only because I had pre-filled out a sample ballot all my selections. A lot of people I saw there seem to go in cold and look over the all the ballot language in the booth, taking a lot more time.

Scientists Speak Out Against Wasting Helium In Balloons

I bet if you actually fused enough H to He to account for the current world usage of helium the required fusion energy would be WAY huge (as in dead, glowing earth huge)

Why We Love Firefox, and Why We Hate It

mark_osmd Re:No equal? (665 comments)

The Chrome way is actually pretty clever and sneaky. That way the web site can't tell you're not seeing the ads, the firefox way makes it possible for them to detect that there's a user ip that viewing content but not pulling the ads. At that point on Firefox you usually get a nag page telling you to turn off adblock and/or kicked off the web site.
