Re: Shitstorm V2
I have no particular objection to a company saying to its workforce "this is what we believe the consequences of the two outcomes will be both for the company itself and you as as member of staff" - and then backing it up with some actual facts, actual reasoned arguments and clarification of which bits were opinion, company policy, etc. (*)
Of course I'd like the same from the wider debate too, so clearly I'm an eternal optimist due to live forever in a state of disappointment.
Well, quite. And also, if my drone could use wifi, 4g, 3g, etc. could it really block all those? Or some sort of custom telemetry on some random frequency? If I'm planning something nefarious with a drone then I'm probably not going to be too scared of OFCOM turning up to complain weakly at the unlicensed spectrum use ...
Actually I'm not sure that a "The Martian" style Hab material needs to be quite as tough. Pressure differentials about the same but even Mars' thin atmosphere is enough to stop the kind of micrometeorites and so forth that the ISS has to worry about...
Re: Hope he's not a smoker
i was watching the first attempt on NASA TV and he was being told to inflate it in one second bursts. It did seem to me that his definition of "one second" was somewhat quick and evidently mission control thought so too because the fourth or fifth "go" command contained the addendum " ... and make it a generous second".
This is yet another good step forward in space exploration and space technology development. But I can't help but feel that the actual thing looks a bit, well, scruffy compared to the various CGI/artist's impressions that were shown around before hand...
Re: The key question
Well, it's not just about the cost of the power. It's also about the cost of the infrastructure necessary to deliver that power such that it can be consumed at any point along the route. Point of Hyperloop being that (a) less power is needed, and (b) it only needs to be delivered at a few key points on the route.
Re: The key question
Well, according to this ( https://en.wikipedia.org/wiki/TGV_world_speed_record#Preparation_of_the_train_for_Operation_TGV_150 ) - about the current rail based speed record - you need a mechanical power output measured in 10's of MW which suggest the total of the various drags are considerable.
Re: "What I say means what I want to say when I say it. More I cannot say."
Hmm, don't agree with the use of FLA for "four letter acronym". You should use ETLA meaning "extended three letter acronym", that's much more IT appropriate...
Re: "...live-streamed the landing from a helicopter."
yeah - I don't get that either. Given that "catching the rocket engines with a helicopter" is actually the plan of ULA for their Vulcan project...
Taking it on trust
So I guess for most people (including the more literate IT types reading here!) we are realistically already at the level where we have to take "secure/unbreakable encryption" claims on trust (because the maths is hard) but once "quantum stuff" starts getting used in real world situations it's going to get worse, right? The number of people who could legitimately claim to genuinely and fully understand how it works is going to go down by an order of magnitude (if not two or three!). 'Cos, you know, this quantum stuff is spooky ...

Re: Middle Naut
Based on in interview with him in a documentary I saw (that was actually more about Tim Peake) it appears that he does have a pretty good sense of humour but that it is very, very, ... very ... dry indeed. Whether that is representative of Russians in general or Cosmonauts in particular, I couldn't say.
There was a recent satellite launch on some similar flavour of converted ICBM (perhaps this one: http://www.theregister.co.uk/2016/02/17/sentinel_launch/ ) where it looks like, even though above ground, there is still some kind of tube that the rocket launches from.
I'm sure there's a technical reason (something to do with the rocket engine expecting a certain back pressure from an underground launch tube?) but it's also amusing to just consider that the rockets get nervous in the open air so they're given a little tube to hide in until it's time to go...
And presumably we'll find out shortly if Musk really does have any "volcano lair" tendencies as, in this situation, surely the temptation to use one's fortune to hunt down the boat's skipper and do something amusingly unpleasant to them must be very, very tempting ....
Absolutely! That was my favourite bit of the Geography O-Level exam - the "here's a nice OS map for your perusal and a number of questions about it" question. Sad thing was that we didn't get to keep the maps afterwards.
Re: Map for The Martian
yup - I spotted that too. I wonder if it was deliberate or perhaps that area of Mars is just "interesting" whether you are an author, a NASA lander or a quiet bunch of Brit cartographers with a dream ...

Not at all an expert on French slang but I was made aware of "zizzi" as meaning the same as "bite", in this slang context at least, by my French colleagues' hysterical laughter at this news item from 2007: http://news.bbc.co.uk/1/hi/england/london/6586879.stm
Re: Why put it all below water?
exactly! Why not just pump seawater out the sea (or a river), pass it through some heat exchanges and then let it back out into the sea? Works pretty well for power stations and they need to get rid of quite a lot more heat than a data centre would ...

not entirely sure how the economics and/or politics work but I suspect this is more "dirt-poor southern state competes with other states to keep company in the hope that billionaire visitors will, in the future, spend lots of money in their state on high-altitude ballooning, hotels, food and lots of other sales-tax earning things" ...

Re: Can anyone* see my web requests if I use HTTPS?
Absolutely true. Where I work this is specifically mentioned in our employment contracts (or at least in a policy doc that is deemed part of our contract). Effectively they MITM every HTTPS because they can set whatever root certificates they like on our workstations. They have legitimate reasons to do this but as a consequence get to sweep up all such data. I'm also presuming that any legislation will at least attempt to be sufficiently broad that they can get such logs from employers too.
If you don't like this then you should only browse personal stuff at home. I nearly added "or on your smartphone" then I laughed at myself.

Re: Why is it curved?
i actually met a few of the Reaction Engine guys at a conference a few years ago and did ask this qustion. Regrettably I don't recall the exact answer but it was along the lines of wanting some down vector to the thrust whilst the airflow was straight (with respect to the fuselage)
Actually lots of evidence that travelling at a constant say 25mph and going straight through lights at green is quicker for you (and everyone else) than going at 30mph, having to stop,queue and then start again. Germany, for example, has been doing this sort of thing for decades with their traffic lights. Similar example on the london underground where they are switching to "moving block" signalling (which attempts to keep a constant speed / spacing) compared to the old "fixed block" where the driver would slam the train to a halt at the red signal because there was no way of telling that the next block would become free in a few seconds so actually they'd have been better off slowing a little.
You probably shouldn't watch the slow-mo child seat tests that they have on which.co.uk featuring similar crash-test-dummy babies and toddlers, then.They do actually put up a warning before them saying that they might be disturbing, which I casually dismissed and then, shortly after, thoroughly agreed with...

MW management style
Having read some of the various claim/counter-claim documents in the HP vs. Autonomy spat I still can't get over the description of the high level "Executive Committee" meetings: "Ms Whitman ... repeatedly adopted the management approach of ... playing country music to the meeting instructing the senior executives attending to take the meaning of the country music songs and apply them to their own management methods".
Sounds like HP is in safe hands ...

Re: A "one newton thruster"
yes but these thrusters are just used for rotating the satellite and, I suspect (although I'm no rocket scientist) that, the 22N ones are for minor orbital changes. Basically these are just for pootling around (*) not for major course adjustments.
(*) - I think the technical term is "station keeping"
"I wonder if I can friend Captain Beaky on Facebook? I've finally proved I'm innocent!"
Firstly, the library hasn't backed down (yet) - they've just sent it back to their Trustees (who are probably the group that would face any legal difficulties). Seems perfectly reasonable - if I were just some random employee then that's totally what I would do too.
Secondly, is there the option of hosting the node but only allowing the exit to see the library hosted content? That should resolve the issue, right? TOR users wherever they are can get to the library content but nowhere else (via the Library node). So no "criminal" traffic can be passing through the libraries systems onto the internet. Or do you think they are arguing that even passing the encrypted TOR in/out stream, which I guess might contain a few instances of naughtiness, is a problem?
Gold FTW ! (when soldering)
I used to work for a company where long life and corrosion resistance were very, very important so almost all the electrical bits ended up being gold plated to some degree or other. For similar reasons, connectors were not allowed - everything had to be soldered. I have to say soldering a gold plated wire onto a gold plated pin was always a real pleasure - it's about the only time even a non-expert can get the textbook solder fillet!

Re: Confused about the re-useables return path?
"Overall, SpaceX fuel tanks are the lightest in the industry, and the engines have amazing thrust to weight ratio" - this also means, I believe, that one of the issues with landing is that even using a single engine at minimum thrust it still has net lift. So it cannot just gently lower itself down at whatever pace it feels like - it has to set a descent trajectory with positive vertical acceleration that happens to end with zero velocity exactly(*) on the pad/barge...
(*) obviously there is a certain amount of tweaking you can do, there are cold gas thrusters and the legs can take a certain range of non-zero landing speeds, but, still, it's tricky...
So about as re-usable as an F1 car then ...
Reuse and price
As per the end of the article I do think reuse and the knock on effect on price are the key. As long as Musk/SpaceX have the financial reserves/income stream to keep on with the Falcon Heavy (and XX) programme then their launch cost per Kg will be tiny in comparison to the SLS which is completely thrown away.
The maximum payload difference may not be such an issue either: one use of such a heavy lift is to take up multiple things, in which case multiple, dramatically cheaper lauches are better. The other is to take up a single heavy thing (duh!) - but what is the demand for that? Any realistic manned Mars mission is likely to need multiple launches of bits and pieces and likely some in-orbit assembly at which point what is the difference between joining 3 things together and joining 5? Well, obviously _some_ difference but enough to be worth spending the entire SLS development cost on? (when they should be spending the money on e.g. working out how to assemble stuff in orbit ....)

... is why you wouldn't want to be an astronaut or cosmonaut. It's already happened in both Russia and the USA both during the Space Race and to some extent during the Shuttle era, and is probably going to happen again with the rescheduled next crew flight to ISS - a bunch of Astronauts and Cosmosnauts are going to have to stand, smile and wave at the cameras whilst repeating carefully written statements about how confident they are and how everything is going to be fine whilst privately thinking "we're all going to die but if I say anything that's the end of my career".
