Comment Secondary sources (Score 1) 1825

NASA discovers little green men on the moon. NASA makes a 2 page press release. Bob writes a blog post where he condenses the NASA press release to 1 page, mostly by deleting every second paragraph. (Alternatively it could be a Javascript and advertising heavy commercial news site.) Slashdot posts an article linking to Bob's blog, rather than linking directly to NASA as they should. One of the first comments provides the direct link (with title something like "This is the link you should be using") and instantaneously gets modded to +5, in reward for having done what the Slashdot editor should have done.

I'm not saying never use secondary sources - sometimes Bob has summarized 50 pages to 1 page (and done a good job of it), or added some insightful commentary. Just don't use secondary sources unless they add significant value, and always include a link to the primary source in the summary.

Comment Re:Staged chute deployment - how's that work? (Score 1) 91

Thanks.

It sounds like this system relies critically on the coefficient of friction between the slider grommets and the risers. Too high, and the slider never (or incompletely) slides and the chute does not fully inflate. Too low, and it inflates too fast and soon, bruising or breaking the parachutist or, worse, ripping the chute.

From the abruptness of the transition between slightly inflated and fully inflated in the space capsule chutes, and the prolonged delay before this occurs, I suspect the friction method you describe is not used. However a slider with some other release mechanism seems likely.

Comment Staged chute deployment - how's that work? (Score 3, Interesting) 91

There is a thing that these chutes do, where on initial deployment the open aperture of the chute is quite small, and the chute looks rather like a sausage. Then later on, the chute abruptly opens fully, and looks like a hemisphere. (The transition wasn't shown in the video in TFA, but I've seen it elsewhere and it is also simulated in Kerbal Space Program.)

How is this achieved? Is it some clever aerodynamics where the chute has two stable configurations and a 'catastrophic' transition? Is there some rope which constrains the aperture early on and then is somehow severed to allow fully deployment?

(I understand why - the first configuration slows the payload sufficiently so that the chute is not torn apart when it fully deploys. "How" is what I don't know.)

Comment Maybe worthless to you... (Score 1) 63

All other things being equal, I'd give raises and promotions to the people who demonstrate that they have a continuing interest in learning more and keeping abreast about subjects relevant to their field than someone who thinks that once they get their degree, they never have to learn anything else. So if you think that "quantifying the time spent in the classroom during professional development and training activities" = "worthless as shit", then hey, it's your résumé, good luck with that.

(Of course, that's just the practical monetary consideration of the matter. Some of us actually like doing these classes just to see what's new and to *gasp!* expand our horizons.)

Comment Re:anecdotal or statistical (Score 1) 507

However, statistical evidence is just an aggregation of anecdotal evidence.

No, sorry, completely wrong.

Statistical data comes from a well defined sample which is designed to be representative of an entire population. Anecdotes have no well defined selection criteria (my grandmother smoked until she was 100, and because I don't want to believe smoking is harmful, I remember and put great importance on this, and forget all the other people I have a connection to who were damaged by smoking) or (often where the selection criterion is 'stuff that happened to me') too little data to draw a conclusion (I've never crashed while driving drunk, so it must be safe.)

"I remember really hot days 10 years ago, hotter than now" holds very little weight. It is your experience (perhaps for every person like you there are 100 with the opposite experience), it is subject to biases of memory, and you've chosen the example retroactively to support a given position. The statistical data is thousands of thermometers measuring temperatures every hour over decades.

Comment Re:LOL - more sickening propaganda (Score 1) 133

*sigh...* Why do I bother feeding the trolls? Oh well, here goes, mostly for the benefit of everyone else who might have accidentally read your incredibly racist, stupid post.

The AVERAGE IQ of Africans is twenty or more points below that of whites. Care to discuss? One genius African doesn't negate that fact - meaning that the more Africans there are in a white country, the worse it becomes for whites. Which is why Africans don't want to live around their own kind, in AFRICA.

So, apparently, is yours for not knowing that racism is responsible for differences in things like average IQ and earning potential of African-Americans. African-Americans are just as capable of learning and performing as "whites" when put into an environment conducive to learning and free of the systemic racism that has plagued this country since its inception. If it weren't for people like you, there wouldn't be such differences.

And the likely reason most "Africans" don't want to live around their own kind is because the people you're calling "Africans" aren't, in fact, African. They were born here, grew up here, lived all of their lives here, have all of their friends and families here, and are integral to the culture that defines us as a society. They're not "African" any more than you're "European" because of your likely heritage, and making such idiotic statements is like claiming that you don't want to live around your own kind, in EUROPE.

And, of course, that completely neglects the fact that most people of African heritage in the United States aren't here because their ancestors came here voluntarily, they were shackled and forced to relocate against their will, likely by those who were your ancestors. And, of course, that unless you're a full-blooded Native American, you're just as much an "invader" here as those you look down upon--except even worse, because your ancestors came here willingly and by force.

So please, stop being such a tool, and the cause of the very problems that you're bemoaning.

Comment Re:Press space to wipe and reenable OS verificatio (Score 1) 167

Sorry for the (partially) offtopic reply, but I just saw your question about Trusted Network Connect here.

I haven't been hearing much new news about Trusted Computing or Trusted Network Connect recently. Ordinarily I'd consider that a good sign that it wasn't moving forwards, however it's looking more like a successful slow-quiet-rollout strategy. Both Microsoft and Google make the Trust chip mandatory on phones, and Microsoft has declared that it's mandatory on all desktops and other devices in a few months. all new devices and computers must implement TPM 2.0 and ship with TPM support enabled , starting one year after the Win10 release. (Apparently August of this year.) The whole design of Win10 is to force rolling updates. It could get ugly if Microsoft simply pushes out all sorts of Trusted Computing crap as non-declinable "routine updates".

The phone lockdowns are definitely leading the way. Microsoft says phone manufacturers must prohibit users from turning off secureboot, and it looks like Google is also enforcing enforcing secure boot which (so far) permitting you to then drop to an eternal-nag non-Trusted mode. Sigh. Not good. I wouldn't be surprised if desktops also use a transition step of enforcing an eternal-nag-mode if you try to opt-out of Trusted Computing. At some point support can simply be ended for the nag-mode option. Then there's no opt-out at all.

You can't sail a drilling platform up to a wharf to unload the rocket, like you can a barge (so your idea would require an extra transfer at sea from platform to barge), nor is it so easy to move around the landing spot to match mission requirements. Having said all that, if barge landings turn out to be sufficiently haphazard, your idea may be economical.
