Comment Re:So what next? (Score 2) 101

If you RTFA (yeah yeah...) you'd notice that this is not an indictment of transportation, but a sign that efforts to reduce emissions from power generation are succeeding. In other words, it's not that transportation emissions are unusually high, it's that other sources of emissions are on the decline.... so you can now unbunch your panties.

The article then laments that efforts to curb transportation emissions haven't gained much traction yet, and notes that higher fuel prices are the best chance to drive efficiency gains and adoption of alternatives. Boo hoo!

Comment Re:Distortion on distortion (Score 1) 271

When using fx boxes to emulate other hardware, you always want a high-power, distortion-free system that can reproduce exactly what it is fed. This way, when you employ "fuzzbox v.1.9" or "fender jazzman-ish rev 6", or the former feeding into the latter, they sound like those things, instead of those things plus new grunge.

This is typical for studios; the repro system is pristine. Because you always what to hear what's there, not what's there plus something the end listener won't hear, and because as I said earlier, no general *music* repro system should be operating in a regime where it is adding distortion -- because that sucks.

There are plenty of high-power, low-noise solutions that allow emulation to do exactly what it was designed to do. You just have to be savvy enough to pick them instead of that Marshall stack you always drooled over...

Submission + - SpaceX Test Fires First Raptor Engine (techcrunch.com)

Thelasko writes: Elon Musk is preparing to unveil his plans to colonize Mars at IAC tomorrow. As a tease to his lecture, he has released some details about the Raptor engine on Twitter, including pictures.

Mr. Musk states that, "Production Raptor coal is specific impulse of 382 seconds and thrust of 3 MN (~310 metric tons) at 300 bar." He goes on to note that the specific impulse spec is at Mars ambient pressure.

Submission + - Should we bring extinct species back from the dead? (sciencemag.org)

sciencehabit writes: For decades the notion of “de-extinction” hovered on the scientific fringes, but new advances in genetic engineering, especially the CRISPR-Cas9 revolution, have researchers believing that it’s time to start thinking seriously about which animals we might be able to bring back, and which ones would do the most good for the ecosystems they left behind. Science Magazine explores why and how we might do this, which animals might be first, and the big risks involved.

Comment Encryption was expensive (Score 1) 114

Computationally that is, I don't think it would have flown in the early 90s and the adoption rate would have been the same it was with SSL (and TLS). It wasn't not so long ago that I actually had to provide resource impact reports on servers where everything would be encrypted. Nowadays (unless you deal with extreme large volumes), encrypting (using an symmetric key that is) doesn't have a significant impact. Web servers, load-balancers, etc can support it without breaking a sweat.

Comment Open source version of siri / echo (Score 4, Informative) 179

The answer is MyCroft

I plan on buying one of these the very soonest I can once they are actually shipping the hardware. Echo is crippled by the many limitations Amazon coded in on purpose -- it's basically something that looks up text matches and does something if it finds one. No language parsing worth a damn. Even so, it's very useful, and within those limits, you can make stuff for it, Amazon's pretty open about it as long as you can set up a secure server (ugh) or use their cloud (double-ugh.) Siri, as per usual for Apple, is a much more closed system, and frankly, it's of no interest at all to me because of that.

Mycroft is completely open source. I have very high hopes for it because of that. I have reams of my own natural language processing code I should be able to plug right in the moment there is a speech-to-text engine I can use directly. Others do as well. Custom apps in the home space, that are actually somewhat smarter than...

I suggest everyone check MyCroft out. Perhaps you'll be as enthused as I. I can hope. ;)

Comment Self-righterous bullshit; the "company" is pissed (Score 1) 77

If I was that Ziegler fellow I'd be consulting a lawyer. Spouting that shit publicly, verges (ha!) on defamation.

I'm not saying what Ziegler was right, although in this day and age, one should show very little loyalty to any corporation because they basically claim "people are our most precious resource" but treat employees like shit.

I've seen staff where I worked, take a few weeks off or take a leave of absence. What they do, is try another job and see if it suits them. They quit the original job, or they quit the new job. I'm not going to judge people too much when they do this, hell, the company is always evaluating if they should terminate you.

At this moment I have two contracts. Place A does not know of place B, but place B knows of me working at place A and they don't care. The type of work is very different and they're not in the same sector. Sure place A could claim some crap, but if they do, I just have to walk and move on to the next gig. They can claim some BS excuse anyways, doesn't matter.

Comment Re:Am I reading this right? (Score 1) 78

The weird thing, if it is the COPVs, is... there was so much attention focused on them after CRS-7. It'd be weird if this was the cause. And extremely frustrating, too, as they're not manufactured in-house. SpaceX surely tests the tanks, so they too would bear some responsibility for it getting past their test procedures, if this is the cause. Personally (as I mentioned elsewhere in the comments), having a composite vessel sitting in liquid oxygen always strikes me as a dangerous situation to begin with.... if we were good at maintaining LOX-composite compatibility, we'd be making the stages themselves out of composites rather than aluminum.

Of course, the COPVs aren't the only part of the "helium pressurization system". Still concerning that whatever it was slipped past them.

Comment Re:Huh. (Score 4, Interesting) 78

The helium isn't used for cooling; it's a pressurant. It's lower mass to make a small COPV and have that store your pressurant in it than to have the whole LOX tank be strong enough to withstand the pressure.

It's always bothered me, the concept of having a COPV sitting around in LOX, though. Ignoring the thermal cycling, LOX and epoxy aren't exactly fast friends. We don't make LOX tanks out of composites because composites tend to become impact sensitive in LOX (there've been some attempts, but it's still an active reseach field, not a "solved problem"). Not sure there's that much difference between making your whole tank out of composites vs. having a composite tank inside of one. I don't know what SpaceX does, if anything, to try to protect them, but the general concept has always concerned me.

To put it another way: the total mass of the universe is about 180000000000000000000000000000000000000000000000000000 kilograms, which is the mass equivalent of 16200000000000000000000000000000000000000000000000000000000000000000000 joules. There is no shortage of "resources" in the universe. Even the rarest of "resources" is available in unthinkable abundance to any entity that has a range broader than a single planet. Not like it's particularly easy to actually exhaust resources on a given planet; you just move from the easiest ones to the much more abundant, but harder to access ones (while simultaneously your technology advances with time, making resources in general more accessible; prices are based on the competition between these two factors, but in the long term generally follow a downward trend)
