Comment Re:Let's teach critical thinking (Score 1) 212

There are almost 300 million people in the US over the age of 14. And to steal a line from George Carlin, consider how dumb the average person is, and then realize that half the population is dumber than that.

I've always thought that was a good joke, except that Carlin was conflating the ideas of "mean" (aka average) and "median".

Though I did see in an old magazine (Mother earth news?) where someone rigged up a stove in their car to generate CO to burn in the engine. Don't know how true the article it was, or how well the car ran...

Oh yes, "wood gas" engines are a real thing.

The process of using oxygen starved combustion to turn organic material into a combustible gas has been known for 175 years. Gustav Bischof built the first wood gasifier in 1839. By the turn of the 20th century, before the use of natural gas started proliferating in the 1930s, in many municipalities syngas produced from coal was centrally produced and distributed via pipelines to homes and businesses to use for heating and cooking. In 1901, Thomas Parker made the first vehicle powered by wood gas.

Comment Re:FFS Beau skip adding the additional links (Score 2) 258

Yesterday I ridiculed someone for complaining about an [un]related article link, because one line at the bottom of a summary seemed like such a stupid thing to complain about. It's still think it's a stupid thing to complain about. Why would this drive anyone away? I'm sure most of the people who would be driven away by stupid things said on slashdot would have left after their first visit.

But I have to concede that this was the stupidest, completely un-related "related" link I've seen yet. I almost felt inspired to complain, myself.

Perhaps the "HD" in "BeauHD" is meant to imply that Beau is the Definition of "High"?

P.S. OzPeter, To answer your second question, milk is mostly water, and water is mostly (by atomic proportion) hydrogen. :D
P.P.S. Yes, I'm Slashdot too. Nice to meet ya.

Damn, some of you people are really fucking uptight! I mean really, how many decimal places to you need to quantify the percentage of your day that was wasted by reading that one "in other vaguely-related news..." sentence? Most of the time, the related-news tie in seems pretty relevant (like today, one Amazon story mentions another Amazon story). Other times, like this, not so much. So what? Are you going to ask for a refund?

Next time try complaining about something that actually matters. Or better yet, do something to make the world a better place.

Comment Subsonic (Score 1) 226

Subsonic fulfils all my needs (mostly audio), and has a fine Android app (also iOS but I've never seen that one), a nice-looking, built-in web app, and is supported by other third-party music players (I use Clementine).

I know you asked for a "device", but if you have a net-enabled device that can run Java, this is a pretty solid option. It was easy to set up (unlike Ampache, which I tried which was pretty useless). YMMV

Submission + - SPAM: China homegrown electronic and world's fastest supercomputer 1

Taco Cowboy writes: Clocked in at 93 Petaflop (or 93,000 trillion calculations per second), the new ShenWei (roughly translates to The Wrath of God in Mandarin) TaihuLight tops the world's fastest supercomputer list

Twice as fast and three times as efficient as the previous leader Tianhe-2, the new ShenWei Installed at the National Supercomputing Centre in Wuxi and comprised of 10.5 million locally-made processing cores grouped into 40,960 nodes (with each node having 260 processor cores) the computer runs on the Linux Operating System

The processor is divided into four core groups, each with 64 computing processing elements (CPE) and a management processing element (MPE). Each core group also includes a memory controller delivering an aggregate memory bandwidth of 136.5 GB/second on each socket. It runs at a relatively modest 1.45 GHz and supports just a single execution thread per core

The chip was manufactured at the National High Performance Integrated Circuit Design Center, in Shanghai. The process technology node has not been revealed

Memory-wise, each node contains 32 GB, adding up to a little over 1.3 PB for the whole machine

Its main applications include advanced manufacturing, weather forecasting and big data analytics, wrote Jack Dongarra in a paper about the new machine ( [spam URL stripped]... )

Pierre Ferragu, tech analyst at Bernstein, said the ranking showed that China was “pulling together all the building blocks of an independent semiconductor value chain”

The system is also rather light on cache. In fact, it really doesn’t have any in the L1-L2-L3 sense. Each core is allocated 12 KB of instruction cache, along with 64 KB of local scratchpad

From a power standpoint though, TaihuLight is quite good. It draws 15.3 megawatts (MW) running Linpack, which, somewhat surprisingly, is less power than its 33-petaflop cousin, Tianhe-2, which uses 17.8 MW. TaihuLight’s energy-efficiency of 6 gigaflops/watt is excellent, which will certainly earn it a place in the upper reaches of the Green500 list

The interconnect, simply known as the Sunway Network, is also a homegrown affair. It’s noteworthy that the older Sunlight BlueLight machine employed QDR InfiniBand for the system network. The TaihuLight one, however, is based on PCIe 3.0 technology, and provides 16 GB/second of node-to-node peak bandwidth, with a latency of around 1 microsecond

Running MPI communications over it slows that down to about 12 GB/second. Such performance is pretty much on par with EDR InfiniBand or even 100G Ethernet, although the latency seems a tad high (it depends on exactly what’s being measured, of course). In any case, it looks like the design team opted for simplicity here, rather than breakneck speeds using exotic technology

“The latest list marks the first time since the inception of the TOP500 that the US is not home to the largest number of systems,” wrote the authors of the ranking. “With a surge in industrial and research installations registered over the last few years, China leads with 167 systems and the US is second with 165”

You have real buttons, adjacent to your late-model Apple touchpad? Fancy! Are they above the touchpad, or below? I prefer to have them below, myself.

On this MacBook, Apple continues with their misguided idea (started with the almost universally-loathed Abominable Puck mouse on the original iMac) that one button should be enough for everyone. Except they decided that this crappy, somewhat tilty touchpad should pretend that the whole thing is a button--better yet, it should pretend to be *multiple* buttons, depending on where your finger is when you click... yet with no haptic indication whatsoever of where to actually place that finger for a left/middle/right click (and woe betide the hapless user who accidentally lets another finger touch the pad while attempting a middle- or right-click).

As one deeply learned and wise person once said on the internets, you "just gotta know where they are".

If that's what you have, and you like it, fine. I have no argument with your subjective opinion. I said, objectively, that this touchpad has no real buttons.

The Magic/Mighty Mouse is almost as bad, but at least I find it usable most of the time... even though it, likewise, has no real buttons.

I forget. Why are we arguing about this? Oh right, you're trying to tell me that I'm ignorant. But unless you're the idiot who designed this thing, I really have no issue with you. I'm happy for you that you like it. Rock on!

And you get lots of positive reviews by doing positive things, like serving great food and having great service, not by hiring a bunch of people who have never been to your restaurant to write good reviews.

...or, you could just go the easier/more effective route: Give in to Yelp's blackmail, and pay them to ensure the bad reviews are suppressed.

Since Yelp is already working to negatively "manage" your reputation unless you pay up, paying them doesn't make you a bad person (any more than it does to pay a ransom to preserve something/someone else dear to you). It's just effectively working to manage your reputation, under unfortunate circumstances.

Sun was no saintly operation, to be sure. I worked there briefly and hated every moment of the mega-corporate lifestyle (not to mention lack of a sense of direction), and went back to working for small companies. I was never a fan of Scott McNealy, but of course it was (and is) difficult to despise anyone more than Larry Ellison.

There were a lot of good people working at Sun, and they accomplished some great stuff, but I have to admit the only reason I wax nostalgic for the company is because I do lot of work with Java (though I thankfully there is OpenJDK) and I feel a sense of shame to be even *that* loosely associated with Oracle.
