Truly energy-producing fusion is not available even in bombs.

Sure it is. The fusion components of boosted and multi-stage bombs produce lots of energy. In two or three stage devices that use inert tampers fusion produces the vast amount of energy.

The earliest known incidence of a three-stage device being tested, with the third stage, called the tertiary, being ignited by the secondary, was May 27, 1956 in the Bassoon device. This device was tested in the Zuni shot of Operation Redwing. This shot used non fissionable tampers; an inert substitute material such as tungsten or lead was used. Its yield was 3.5 megatons, 85% fusion and only 15% fission.

The public records for devices that produced the highest proportion of their yield via fusion-only reactions are the Peaceful nuclear explosions of the 1970s, with the 3 detonations that excavated part of Pechora–Kama Canal, being cited as 98% fusion each in the Taiga test's 15 kiloton explosive yield devices, that is, a total fission fraction of 0.3 kilotons in a 15 kt device.[35] The 50 megaton Tsar Bomba at 97% fusion,[36] the 9.3 megaton Hardtack Poplar test at 95.2%,[37] and the 4.5 megaton Redwing Navajo test at 95% fusion.[38]

Comment The Math, aka Big Freaking Deal (Score 1) 37

We have this:

AT&T To Cough Up $88 Million For 'Cramming' Mobile Customer Bills

And this:

Through the FTC's refund program, nearly 2.5 million current ATT customers will receive a credit on their bill within the next 75 days, and more than 300,000 former customers will receive a check.

So, $88000000/(2500000+300000) = $31.43. Thanks guys, I'll try not to spend it all in one place.

When you trade money for news, you tend to get the news that makes the most money. It's human nature, unless controlled by regulation. Just as corporations, utilities, colleges, all mostly get financially out of hand unless regulated, because people are mostly naturally greedy. There's scant sense of fairness, and gross excess of "take the market for all it can bear."

Look, news is all mostly biased anyway. Biased by what they cover and what they choose not to cover; by the editor's influence; by the publisher's influence; by the advertiser's influence; by the stockholder's influence; by ridiculous "equal time for superstitious nonsense" policies (because the news consumers are bewildered, so in order to get their money, they are pandered to), etc. I'm just not going to actually pay for more bias.

It's a complete waste of time to put a paywalled link in front of me. Not going to click it if I know what it is; not going to stay if I am snookered into clicking.

For news, here's what I want: facts and relevance to actual news. Not the Kardumbians, not some actor's opinion, not breathless reporting of some lab result as if it was tech coming down next Friday, Politics, cover the candidates and what they say. Even handedly. Don't leave some out (Sanders, cough) don't over-cover some (Trump, cough), don't report bland, content free remarks as if they were incoming legal doom (Clinton, cough)... you get the idea.

Simple enough, you'd think. Just do a good job. But they don't. Okay then, fine. But expecting me to pay for that crap? Not happening. They oughta pay me for having to fact check every goddam thing they write and speak about.

Comment Re:How many bits? (Score 2) 103

I work for Dolby Laboratories, and am deeply involved with high-dynamic-range content creation and hardware.

We created the SMPTE 2084 standard HDR EOTF (electro-optical transfer function.) It turns out that human perception is such that by choosing the luminance for code values to be just barely indistinguishable from the adjacent ones, you can get 0 to 10,000 nits (10x as bright as this Panasonic display) with only 12 bits. SMPTE 2084 is what all HDR TVs are using today.

Comment News flash: Average income is deceiving (Score 0, Flamebait) 158

The average income of 10th through 70th percentile - in other words, most citizens - is $32,245 / year (source, EPI Data Library - Wages by percentile.csv, 2015 [latest] row).

Over 40 million (out of 319 million, or about 12%) of US citizens are going hungry (feedingamerica.org).

The social safety net isn't safe, nor particularly social.

I'm sure we can expect relief from the Trump administration (cough... choke.)

But hey, let's worry about tech interns. My blinders need a workout anyway.

Slashdot Editors / owners / etc.:

o Please stop supporting paywalled sites.
o Please stop supporting sites with closed comment sections.

These things are bad for the web and the web's denizens -- of course not for the ethically crippled sites themselves, as we are their product, and both payment up and dissent down are multipliers to their bread and butter.

The paywalled sites are monetizing the news, and that almost always makes for biased reporting.

The closed comment sections make for echo chambers, and that creates an environment where fake news and agitprop flourish.

Same thing to my fellow slashdotters: if you support bad actors in bad behaviors, they will naturally persist. So think about that before you click through the next time someone thrusts a paywalled or comment-bereft site in your face.

Thanks for reading.

It means that we are now far more removed from access to the metal to even do a lot of the optimizations that we've done in the past.

Well... no, it means that you are, perhaps. Some of us still write in c or c++, and keep our attention on the details. You can tell you've run into one of us when the many-functioned app you get is a couple megabytes instead of 50, runs faster than the fat ones, and doesn't suffer from black-box bugs inherited from OPC.

I always thought that the user's CPU cycles and memory were things a developer was obligated to treat as the user's valued resource, and so not things to waste.

I know, totally out of date thinking. It's ok, I'm old, I'll die soon. :)

Comment machine code ate my neurons (Score 1) 381

But can you program in Z80 and 6502 machine code?

Yes. But more importantly, I can program in 6809 machine code. Including building all the index modes. Which, back in the day, is one of the things that saved me from having to design in, and then program, CPUs like the 6502 and z80, both of which are seriously anemic by comparison. But I prefer to program in assembler. Because I'm sane.

My affection for the 6809 ran so deep that I wrote the 6809 emulator you'll find here, which required me to implement the entire instruction set from the ground up.

But yeah, I can write machine code for about 10 microprocessors. And you know what? In the day... that was useful. I could read (E)(P)ROM dumps, I could cold-patch... but today, I just wish I could get the brain cells back. :)
