The GNOME Foundation Is Running Out of Money

WalksOnDirt Re:Gnome go home (689 comments)

They're broke.

Indeed, but you should also mention it should have been "you're broke". It's obvious, of course, but it happens so often that some might have missed it.

Tesla: A Carmaker Or Grid-Storage Company?

WalksOnDirt Re:Panasonic (151 comments)

The current Tesla cells are too expensive for grid storage. Nickle and cobalt are not cheap. Nothing says they can't make two types of batteries though, nickle cobalt for cars and manganese dioxide or iron phosphate for the grid. Or they could have a nice lithium sulfur chemistry they could use for both; there has been a lot of recent development in that area.

National Ignition Facility Takes First Steps Towards Fusion Energy

WalksOnDirt Re:if this keeps up... (127 comments)

...D2O which is expensive but abundant (it makes up about 1 part in 40 million of water molecules)...

That 1 part in 40 million figure, while not wrong, is misleading.

Quoting Wikipedia:

It [duterium] has a natural abundance in Earth's oceans of about one atom in 6,420 of hydrogen.

So the hydrogen in the ocean is 1/6420 deuterium. Getting two of the deuteriums into one molecule is rare, but we don't really care. Chemical bonds are unimportant energetically compared to nuclear reactions.

Ask Slashdot: Should Developers Fix Bugs They Cause On Their Own Time?

WalksOnDirt Says who? (716 comments)

A builder builds a wall. A week later, bricks begin to fall out of the bottom, but he continues to build the wall higher. In most cases, he would have to replace those lower bricks at his own expense and on his own time.

If the builder is an independent contractor it will depend on the bid. If it is time and material he won't, but if the contract is for the job he will. If the builder is an employee he is never responsible: He either learns not to do that or he should be fired.

It is the same for software development.

Study: Some Antioxidants Could Increase Cancer Rates

WalksOnDirt Re:Not very surprising. (117 comments)

The lack of living grandparents probably has a negative effect on a child, or even might prevent his birth. Not a large effect, though.

23-Year-Old Chess Grandmaster Whips Bill Gates In 71 Seconds

WalksOnDirt Re:Big deal. (449 comments)

Carlsen played a non-standard opening and included an unsound sacrifice. He had probably looked at the first few moves for his blitz games, but no deeper since he would never play it in serious games.

Gates had two minutes for the entire game. For someone who is not obsessed with chess that is not enough time to make even sort of good moves.

Incandescent Bulbs Get a Reprieve

WalksOnDirt Re:Freakin' Riders. (767 comments)

It's a 50-200-250 three way, and that is the 200 watt level. A pure 200 watt bulb would be even brighter. At 250 watts it is 4240 lumens, but I rarely use that.

Incandescent Bulbs Get a Reprieve

WalksOnDirt Re:Freakin' Riders. (767 comments)

They are never bright enough.

I just checked, and I am using a 3660 lumen bulb for reading. I've yet to find any CFL or LED light that comes close.

Of course, nobody has talked about banning them, but I'd like to switch if I could.

Power-Loss-Protected SSDs Tested: Only Intel S3500 Passes

WalksOnDirt Re:So make the power reliable... (293 comments)

My guess is, shitty hardware. I've never seen this happen unless the batteries were bad.

The UPS was brand new and from a reputable source. The computer, not so much. I wouldn't have expected the computer type to matter if it could run on line power, but apparently it did.

Google Helps Celebrate 100 Years of Cr_sswo_ds

WalksOnDirt Here it is (27 comments)

Why do these things always make the main page a day late? I had to search for this.

Took me almost an hour, a lot of which was trying to figure out "one way to store data".

What Sci-Fi Movies Teach Us About Project Management Skills

WalksOnDirt Re:What Sci-fi movies? (186 comments)

What other sci-fi movies are there?

Wow, there's a ton, but it is hard to think of them out of the blue. A few were:

Silent Running
Galactic Quest
Real Genius
Short Circuit
Men in Black
The Last Mimzy

Good questions, actually. The interviewer was an idiot.

US Issues 30-Year Eagle-Killing Permits To Wind Industry

WalksOnDirt Re:Holy Biased Presentation Batman! (466 comments)

Considering the size of the US, most birds will never see a tall building in their entire life.

But how many windmills will they see if we generate, say, 30% of our nation's electricity from wind? I don't know if bird or bat kills will be a serious problem or not, but it should definitely be researched.

A War Over Solar Power Is Raging Within the GOP

WalksOnDirt Re:Sucks to be them. (1030 comments)

If they really wanted to be fair, they'd charge every person hooked to the grid for their share of the fixed costs, PLUS the variable cost of how many kilowatt-hours they use. But in many places this is not currently legal.

Then we need to make it legal. We also need demand pricing, which I dislike, but which will mostly help solar people. New times require new laws. It would be nice if they could accurately reflect the cost of power, but I fear politics will make that impossible.

EPA Makes Most Wood Stoves Illegal

WalksOnDirt Re:Which company bought this 'new' rule? (1143 comments)

... but they're illegal because they won't spend a fortune fitting rare-earth metal infested catalytic converters and other emissions systems ...

Rare-earths in a catalytic converter? That's the first I've heard of that. That could bring down the cost quite a bit, since rare-earths are quite a bit cheaper that the precious metals, like platinum and palladium, that I'm used to them using.

Our bodies can break down natural trans-fats, no problem.

WalksOnDirt Re:Outright bans are not smart (376 comments)

uh, butter has 0 trans fat.

Only in the sense that it falls below the legal limit for labeling it. There is definitely some there. So, should we ban butter?

Callisto May Explode

WalksOnDirt WalksOnDirt writes  |  more than 5 years ago

WalksOnDirt (704461) writes "Russian scientist Eduard Drobyshevsky suggests in Pravda that the conductive icy shells of the moons of outer planets can under go electrolysis because of movement through magnetic fields. The resulting hydrogen and oxygen can explode, endangering Earth. He says Titan's explosion 10,000 years ago created Saturn's rings, and when Calisto goes it will lead to nuclear winters on Earth."
