Au oh, there's gold in them thar server farms, so lead the way

AdamT

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!

SpaceX's blast shock delays world's MOST POWERFUL ROCKET

AdamT

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...

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 ....)

And this sort of thing ...

... 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".

Bridge, ship 'n' tunnel – the Brunels' hidden Thames trip

AdamT

Re: I can't resist

I think Enderby's Wharf is at the site of the current Alcatel facility (near the Blackwall Tunnel south entrance). When I worked there (a couple of decades ago when it was still STC) a lot of the cable handling equipment was still there although cable hadn't been made on that site for quite some time. Things may have changed since then, of course...

Re: Thames Tunnel

I was lucky enough to get on the "walk through the tunnels" trip they did when line was closed for extended engineering works. I suspect the last photograph in the article (of random people walking alone the lines) is actually from that event as I have a very similar one myself. I think they have done a pretty good job in the end with a reasonable balance between preservation, exhibition (albeit that you won't really see it from the trains) and waterproofing!

There is also a slightly nerdy thrill from walking along tracks through a tunnel and occasionally stepping on the live rail...

The huge flaw in Moore’s Law? It's NOT a law after all

AdamT

Re: Bah!

Umm, it's just a english idiom rougly meaning, in this context, something like "seriously" or maybe "professionally" and implying that this was when he got seriously stuck into that business. I think originally it was used to distinguish between practice and "for real". For example "shots fired in anger" meaning you were shooting at someone with intent as opposed to just practicing.

(Here's hoping that was a genuine language misunderstanding and I haven't missed some joke and patronisingly explained it to you anyway!)

FBI alert: Get these motherf'king hackers off this motherf'king plane

AdamT

Re: oh hell....

I used to work with someone who had formerly worked on fitting out customised private jets - "client wants a diamond encrusted plasma TV that rises out the footboard of the bed", etc. etc. I think the actually restrictions were even tougher - they couldn't even share a power cable with the avionics. Obviously at some point there must have been some interaction but the point was there had to be no feasible way that any failure of the entertainment kit could have any impact, no matter how tiny, on the actual flight systems. I think he left because jumping through all those hoops took the fun out of the "how do I diamond encrust a TV?" aspects of the job ...

The Internet of things is great until it blows up your house

AdamT

Re: Deeper thought

Well, can't speak for the rest of the world but assume it would be similar to UK, but, for example, all central heating boilers/furnaces have to have a whole range of electrical and (I think) thermo-mechanical interlocks. So the external input to the boiler (from the controller) is just a "heat demanded" signal. And, sure, I leave my central heating on when I'm on holiday without worrying about the boiler exploding. (with thermostat turned down obviously - I'm not a CO2 monster!)

Re: Better safe than sorry...

According to the BBC article I just read the "boosters" get reused (I think the first stage would separate into engines plus tank and the tank gets lost) and the mechanism is: some kind of heat shielding, a parachute and then a helicopter "plucking it out of the air". Which all sounds pretty hairy to me...

HOT HOVERSHIP-ON-HOVERSHIP ACTION: SpaceX ready for barge boing

AdamT

Re: SpaceX is seriously cool

All very, very true. But there is a rather good interview (find it on YouTube) with Elon and his brother (who was a big investor in SpaceX too) where the brother says that the results of first few tests - which all ended in, errr, well, I believe Rapid Unscheduled Dissassembly is the current phrase - were almost cool enough to warrent the expenditure in their own right. And the expression on Elon's face suggests that he didn't quite see it that way ...

Answer (A) is far too complicated. I think it should read:

A - Put "FIX ME !!!!!" in the general vicinity of the bug. Leave the company.

No further clues should be provided so that the person who finds it next isn't quite sure what you found or whether you actually had any idea of what needed fixing or how to do it.

Elon Musk's Tesla set to unveil home storage battery

AdamT

Re: Count me in, but...

Sure, charge/discharge regime is an issue with battery life. But Tesla now has (a) an ton of R&D on this subject and (b) a ton of experimental data (from the cars themselves) of running batteries at their limits with charge/discharge cycles based on traffic flow and heavy-footedness of the driver. Which might be a reasonable proxy for sun/wind cycles...

Noses?

You'd think the astronaut's own noses would be a fairly good judge of the presence of ammonia particularly at any level approaching dangerous. Or maybe the sensors are so incredibly sensitive it would be normal for them to detect levels that the human nose cannot.

Re: Transport aircraft

Starting to sound a bit like some of the ideas in Charles Stross' Singularity Sky/Iron Sunrise series, if I recall correctly. I think the idea was that you could have faster than light communiciation (via entangled particles) but only once a set of pre-entangled particles had been delivered to you at (sub)light speed. Or something like that.

Samaritans 'suicide Twitter-sniffer' BACKFIRES over privacy concerns

AdamT

Umm, Twitter != private ?

OK, so I haven't read all the T&C's of Twitter or considered all the possible options of blocking people and the setting that only lets your followers see your tweets, but .... basically, if you tweet, even with no followers, it can still be read by anyone who has some means of finding it, right? And this could include random search terms, following a hashtag you might have used or that it is a reply to some other tweet you were looking at. So how can this be an invasion of privacy? They are just making it easy to pay attention to something that someone said effectively in public. Arguably creepy, though.
