It's more likely a consequence of what ham radio/CBer discovered about the new fangled electric petrol pumps. While the mechanical ones just worked (TM), the electric ones forgot how to count if uou held down the press-to-talk key. Yay! free fuel! Eventually, the garages noticed abd put up signs, similarly the pump makers were forced to do a better job.
The claim of hazardous environment doesn't cut it when they then don't force you to ground your car during filling, the the things like light fittings on the forecourt are not safe for use in hazardous environments either.
Re: Don't get too upset
So these potential projectiles are only a problem if they are electronic and switched on? The same device turned-off is suddenly a not-projectile, and the wooden mini chess set with magetic pieces just doesn't count?
Which law of physics is that? Must be one of the classes I skipped /
Re: Transparent aluminum (sic)
How about transparent aluminum oxide? Call it saphire if you want. Bit expensive for a whale tank though.
They don't need to. The government come knocking at the door, and Apple just hands over everything. However, they haven't put a back-door in anything, nor given access to their servers; hence no lie. Call me a cynic.
Why cut it live?
The thing is that these cables take a long time to lay, and you get loads of notice as companies group up, sell prospective bandwidth, issue requests for quotations to cable manufacturers, book cable laying ships, etc.
So, you put in a splice after the cable has started being laid, but before it is operational. You have loads of time to do it, and it could be done before people notice. Yes, it's probable that the cable is not 100% dead for 100% of the time that it is being laid, in order to ensure that they don't lay dead bits, but it's probably not live 100% of the time either.
The other thing is that it would be relatively easy to pay the layers to look the other way, while you play with it, and/or implant someone in the crew.
However, it's far easier to just hook in where the cable lands.
Re: I can't actually remember the last time I purposely used the Android Browser
With the stock Android browser, you can get into an extra settings page and set any user-agent that you want, including NCA Mosaic. Sorry, from here can't remember how, but istr you enter a specific non-URL string and then select something weird in settings or somesuch.
I actually run Firefox because I also run it on one of my boxes too, so have access to open tabs, and bookmarks. However it doesn't do a good job with the "request desktop site" imho.
Re: Apple Pay? Not if they use the current iTunes approach..
I'm in this boat(but have 2x iTunes accounts). I also have the same fchsking problem with Google and their app store too - even for FREE apps. It makes me want to do illegal things to some commercial manager at Google.
Microsoft is even worse though. For Win7 /Office 2010, we have 8 different versions that are all enterprise - but for different countries. We coukdn't even just use the English plus language packs, because changing the language screws some things up, and even then parts of Excel don't work
However there is only ONE version of OSX - just install and set language (haven't bought anything from the app store - everything direct from Adobe, etc.)
UK too this winter
Sounds like a prediction of this winter in the UK - except that the temperatures will be 4°C instead of 40°C. Anyone else remember going to the local elecy shop to get a timetable for when there'd be power in your zone of town, and lighting by candles?
No, they'd just have to change the storyline a little. The printer would only work from the power supply socket in the command module. The power supply in the command module would then fail, and they'd need to print a new part to fix it... Something would have to be built using just a bog roll, a staple stolen from a printout, the foil packet of a space curry meal..... in order to power the printer from the socket in the Service Module, but the computer to control it would still be in the CM - so they would have to try to hand cross-compile the code for the incompatible computer in the SM.....
Re: time to seperate switching amplification and processing
I do that with my Panasonic Plasma (Optical output for selected input channel). Also has the advantage, that it is not smart and does exactly nothing except display pictures and has a digital tuner. It also outputs the audio on one of the HDMI inputs, but my amp does not have HDMI, so I don't use it.
An advantage of it is that it also delays the optical output by the same amount as the time taken by the video processing to maintain lip-sync.
"...write off the rovers after 90 days..."
It doesn't work like that. You don't assume that your car will stop working after 2 years, but when you buy it, they only say that it will work for 2 years (after that you are on your own and have to pay if something happens).
What happens, is that the specs call for a reliability figure and a time (e.g. my last project had a reliability figure of 99.999999% for 15 years of life). Everything is then designed for that lifetime/reliability. So in the case of the rover, there would've been "somepercentage%" probability that it would last 90 days. If it died before that, someone would've been sent to the American equivalent of a Siberian weather station (Guantanamo?). The expectation would be that the mission would last longer than 90 days, but you need to draw a minimum line in the sand to start with.
Everything would've been set up and funded to operate the rover for at least 90 days, and after that, additional funding and manning would be provided if it still worked, and the resources were not needed elsewhere (e.g. time on NASA's deep space network.
The wiper blade idea has been mentioned in other posts, but the dust is not like Earth dust. It is extremely gritty and will scratch anything it's dragged over. Also, if it is charged, that won't necessarily help anyway, because it could just jump back over the cells when the wiper blade has passed over.
Re: Has it?
I'm not on it, but Mrs. Bachelor is, and she did some research that showed some new posts are automatically buried and not shown to everyone who subscribes. So to be able to find old posts when even new ones might not show up? - you may need to use the AccessAll API included for the NSA.
Re: @Angela Taylor
So if an email server tries to send an email, and there's no MX record the email still gets sent? News to me. And the list-server doesn't drop the email address from the list because the email address doesn't exist?
There is a possibility that a human will see a message that an email wasn't drlivered, and they might try a 2nd time (and it will probably fail again, and they'll probably give up). However any invoicing/ordering etc. system will just fail to deliver the email.
Afaiac the email will normally be lost.
Is it that different in England, where you now have to apply for permission to protest about something? (And the request can be denied, or the protest takes place, and the police beat anyone there, even if they are just passing by).
Re: Why not ask SpaceX?
Well I believe that the normal approach will be to launch the sats in groups of 4 on Ariane 5 (which has an excellent record for very precise orbits). However, they wanted to launch fewer for the first launch to test out the design of the satellite to allow the following satellites to be modified if required. Hopefully, the booked Ariane launches will go without a hitch. Note that SpaceX has also failed to deliver 2 payloads to their correct orbits.
Also the European union /ESA probably would prefer to use Ariane because it helps to assure European access to space (Ariane was originally developed because the US said that Europeans could launch sats on their rockets, but would not be allowed to keep any money made by the satellites - imagine how the telecoms market would look in that case). This may be seen as similar to SpaceX receiving a large amount of cash so that the US can launch cargo/people to the ISS without using Russian launchers, or satellite manufacturers in the US being banned from using launches provided by the Chinese.
Re: Possessing "Information useful to a terrorist"
So is a bus timetable "Information useful to a terrorist". Basically it seems that the law was written by a bunch of nitwits, or was deliberately vague to allow it's easy use to arrest, hold and convict people. (notice that's "or", not "XOR")
Re: Geneva convention
I suspect that the original poster was refering to the requirement (request?) to not simply bomb the fuck out of whole areas containing "civilians". The murdering/maiming aught to be constrained to the "enemy combatants".
Personally I don't see anything civilised about a list of rules for who it is ok murder. From this I don't understands about "innocents" being murdered (probably because I don't understand the concept of being "guilty of being on a list of those ok to be killed). While I'm at it, why do the press then go on to say "...including women and children" - wtf? is it suddenly ok to murder men? It's only a problem if you murder women or children?
Re: The good news, of course, being...
GPS (and Gallileo) receivers are purely passive devices. They receive signals from a number of satellites and use those to calculate their position. They transmit nothing. The only way for someone to track you is to have something else that then transmits the coordinates that the GPS receiver calculated (or if you forgot your aluminium foil hat; by reading your mind).
That may help in one regard, but how long between you leaving your phone on a table in a Starbucks, walking around a bit, realising that you've lost it and then being able to access said Google service to lock your phone to prevent someone reading it's contents?

Re: Very impressive re. semantics
Unfortunately I bought all the sequels a couple of years ago before I found out they weren't actually written by Arthur C. Clarke. When I read that he gave storylines for the books, I read them anyway to see where the story went, but the writting style was depressingly different.
Re: Captain Future's enemy had one of those.
The last time I thought about it, it seemed evident to me that the force towards the "front" would exactly equal the force towards the "back".I guess that you come from flatland and can only thonk 1-dimensionly. If you think 3-dimensionly and use vectors, you realise that the conoical sides are supposed to generate a net difference in one direction compared to the other. I'm not saying it works, but hey, that would be a great thing, no?
Bit of a pants vacuum chamber then. Ours have bulk-head patch panels that allow passthrough of cables, fibres or waveguides. Thec whole idea is to have a vacuum inside it but be able to connect your kit up to stuff outside to test it.
Re: @Paul Crawford
Nah, 2.5kW is in the class of reasonable (big) size imaging or science satellite. Big communication class is more like 15kW - 22kW. Of that maybe 1kW is used by the platform and the rest is for the payload.
As for solar panels, I'm not sure I believe 40%. For space you need GaAs, not silicon because of the radiation, especially as you move out of LEO orbit and out of the atmosphere. I think maybe 32-35% might be achievable at the cell level, but your panel isn't 100% cells - you have wiring, mechanism, other circuits, etc. Outside the atmosphere you get an average insolation of ~1370W/m², but as has been said, that drops to ~40% by Mars. Given that I don't have Mathcad on my mobile, I'll leave the calcs to someone else.
The Russians had quite a few satellites with thermal nuclear power plants that would go nicely with this tech for getting to/from the outer planets.
Please don't get me wrong. I wholeheartedly agree that this is needed, and I like the look of what they are proposing. I just think it a bit disingenuous to compare the launch costs of this and a geo telecoms sat. (Just like if I say that my bicycle is cheap because it costs less than a Rolls Royce)
Re: How many orbiting satellites can be put up there?
It depends. If you want to put something on the equitorial geo-stationary belt, then yes, there is slot allocation. However this rocket wouldn't even manage to get itself anywhere near on a trajectory in that directdion, let alone a payload.
In Low-Earth Orbit, there is a generally agreed rule that if you put something up there, you have to make sure it comes back safetly and doesn't just litter. The new Metop sats had a problem with this, and the redesign to carry enough fuel to de-orbit safetly was significant. However Metops are also significantly bigger than this rocket can fly.
That leaves the little micro / nano satellites etc. I think that the rules generally depend on the launching country, and are generally more relaxed. You generally have to ensure that it will de-orbit within a certain time-frame, which normally just means putting it into the correct orbit. However, for example the law in the UK says something like if you want to launch something into space, then you have to get it up there and back by chauffeured Rolls Royce and jump though a few hoops on the way, while wrapped in red-tape.
It's a bit of a bad comparison to say that it normally costs over $100m to launch a 5T satellite to geo-stationary orbit, and then say that this rocket will launch 0.1T to LEO for $5m.
It's a bit like asking why does a flight from the UK to New Zealand cost so much, when a Tuc Tuc ride in Tailand only costs £0.10.
Re: @ AC
It's very well saying that the intercept rate is meant to be over 95% - I have specifications for projects that say all sorts of things. You just issue a request for deviation, or a specification waver, and the nasty "meant to be" just goes away.
There was an interesting article published a while ago, and then a similar one more recently by the "Bulletin of Atomic Scientists". It covers how the Iron Dome interceptor works, and suggests a possible kill rate. It's interesting reading, but suggests that 95% may be the miss rate.
I remember having all sorts of problems with a domestic appliance I was responsible for, because the the li-ion cells used inside the battery pack are nickel plated! There is no excuse these days for not knowing that nickel can cause sesitivity.
"More on that story please!"Well let's see. From where I was working at the time, it was sometime in the 90's. Some details are deliberately left out, like the country, airport, aircraft etc. As I understand it, I could use the investigation in general terms as an example when talking about investigations, failures or systems engineering, but certain details that aren't relevant to that use might make people blush. So here is an example of a system level failure and a small part about the investigation that is worth baring in mind when designing equipment that might be expected to undergo post mortem if something goes wrong.
Pilot flying a small regional jet came in to land and set the engines to idle (oops 1). During final approach, he decided he didn't like something, and decided to do a go-around, so he throttled the engines to 100%. The engines now being below nominal operating temp because of the time spent at idle, throttled up a bit, but not to 100% (if you go from 0% to 100% in a sudden jump, the turbine blades heat-up, expand quicker than the outer of the engine and things get really noisy really quickly).
Realising that he wasn't getting 100% thrust, the pilot decided that he was going to have to land anyway, so changed his mind in a hurry, and got the plane onto the runway. Sometime around now, with the engines up to nominal temp and with the throttle still at 100% (Oops 2), ramped up the trust to the max. Plane shot down the runway like a bat out of hell, overshot and went into a forest.
They scrambled a helicopter to locate the plane as it was a bit hard to follow the random path through the trees. The investigation could not interview the flight crew and reconstructed evens from the flight recorders, radar records, positions of controls, etc. We were asked to retrieve whatever we could from the built-in records in our unit. The unit does a built-in-test (BIT) every time at start-up, a fuller BIT when commanded, and some periodic on-going checking during normal use. Also any anomalies are recorded - all done to identify possible faults for maintenance.
The box was a bit of a mess as I said earlier. The E² (effectively flash that is erased byte at a time instead of page at a time) dies were taken to the manufacturer who had a nice test set-up that could probe directly on the bond-pads. Can't remember which manufacturer it was, but it's likely that they don't exist by that name anymore and have been bought and assimilated so many times it would be difficult to find out. Anyway, the data was read-out of the die, and for speed was copied into a new chip and plugged into an engineering unit to read-out the logs. Separately, a manual search was done through the raw data to confirm that nothing was missed by the log read-out.
Re: Factory Reset
Once worked on an unfortumate investigation after a plane overshot the runway, cut down a mile of forest, and eventually caught fire, minus the wings. Most survived, apart from the pilot, who actually had a lucky escape from questions about his actions.
Anyway, the aluminium box was crushed and melted. All the PCBs turned to ash and a pile of glass fibres. The flash memory chips were left as just the dies as the glass seal that glued the ceramic top and bottom of the dil package together melted...
However, it was possible to read all the logs off the dies to reconstruct what had happened.
And yes, we used long-nosed pliers :)

Real reason for the Delay
You only have to look at the unique selling points to release why there's been a delay. 160PB per rack, huge datasets, massive processing power...
All the first units are being shipped to the NSA as we speak. Once NSA have enough to collect and monitor all the RAM/disc of every single PC/Mobile on the planet in real-time, they will slowly be available on general release (about 2018 onwards).
I think that the performance improvement is oversold. It seems to me that the reception of this video over RF in the UK would've taken 10 minutes, whereas the reception of light from space, passing through the atmosphere would've taken from 2 days to 2 weeks, depending on your luck with the weather.
"Mr Mansfield voluntarily gave us his email address..."
Bollocks. You forced him to do it, just so he could find out if he could have a home delivery. In addition, you probably forced him to do it, just so that you could harvest his email address to illegally spam him.
It is a shame that the judge award "unspecified damages". I'd suggest 1 week chained to railings in public, with a rule that "anything goes". "unspecified damages" probably isn't a sufficient deterrant, whereas boiling tar over the testicles might be.

Re: you have to heat it quite a lot before it starts to work
But aren'f Lithium Air cells primary cells (non rechargable?)
Well if it takes 38 million gallons to flush away a piss (for my tpilet it's 4 litres), then only 50 gallons for a shower sounds utterly reasonable.
The fact that normal base-stations don't transmit upwards is just to save wasted transmitter power. If Google wants to put something up there that transmits downwards, then that's fine. I think that most mobile terminals (*) actually transmit in every direction, so they don't really care where the "base station" is.
As for frequency re-use, that is another issue. Normally the telcos size each cell to avoid overlaps using the same channels. So if you want to stick something else in the same space, the normal base stations will have to stop using certain channels to allow Google to use them (even worse to completely re-plan their spectrum usage on the fly.) This would reduce the total bandwidth available to the telco's basestations (although if they get the bw from Google, they could compensate).
I would have though that in congested areas, they wouldn't really want to do that. The only thing that I think would work would be if the telco reduced the cell sizes in the area where the balloon points it's antenna to effectively get an extra base-station in the middle, that wanders through their network as it moves overhead. In that case it would need very good pointing accuracy to ensure that it didn't bleed into ajoining cells using the same channels.
Another issue is that the stratosphere is a lot further away than your normal base-station, so mobiles will have to use more power, and timing will become more of an issue.
(*) There are rumours of a handset that only transmitted in varying directions if you were holding it wrongly.
Re: Off topic but relevant to UK IT
Meanwhile I've just been told by Telefonica that I cannot even have a line, let alone ADSL or 30mb in the house I'm renovating, even though the line's already there. Thankfully I have some contacts in the Sat business, but Satellite internet is not ideal. My other option is to start a Ltd. company with CIF number and order dedicated fibre, but it's only for ltd companies; just paying 300€ month being self employed is not enough.
I read a report on this elsewhere, and that seemed to suggest that the "spooks" did file an accurate flight plan. It suggested that the problem was that the ATC system "forgot"hat airspace is 3D and that the plane woukd therefore overfly everything, with no need to re-route anything.
Re: Hmm, radiation increases as you
"Sometimes your budget only allows you to plan for 20% of the foreseeable issues."That would've been a fine excuse in 1960. Since then, we've sent up sats with detectors on, and even dedicated sats. We know what the environment up there is like, and it's not even amongst the "secret" data. Radiation is more than foreseeable.
Their orbit seems to be extremely low (which makes things easier as the atmosphere will shield them a lot better), but for example in one of my recent projects we were seeing a radiation triggered glitch in a simple op-amp at least once a day. You then analyse the effects of those glitches and design the system to ignore or cope with them. Resetting a 16 day timer on a mission with a lifetime of less than a month does not sound sensible.
I was wondering that too. Considering that all the Starbucks or BTopenzone and the like have no protection, then it's no surprise.
What this guy should be saying is that the WiFi standards group are still completely crap if they cannot implement a standard that allows anyone to connect without needing a password, and then for the two devices to negotiate a secure connection between them.
The current standards either have no protection, or the requirement to enter a 140 bit key on an on-screen keyboard the size of a postage stamp, and no way to know what that key is unless people stick post-it notes up on every lamp-post.
As for honeypots; aren't they one of the reasons for VPN?
Re: Space Elevators
On a similar line, we should stop building cars; obviously a dead-end technology. Everyone knows that matter transport is the way to go, and there have been a few theoretical papers and at least 1 photon demonstation that it is possible!
Re: There are 2 interesting claims about this.
Another big difference is that Dragon 2 will have to be "life-boat" capable, which means surviving 7 months attached, and able to depart by itself at the drop of a hat. As far as I am aware, the current Dragon can only survive for a few weeks, maybe a month tops.
To be able to depart at the drop of a hat, the Dragon 2 would need at least manually controllable manoeuvring thrusters, like the Soyuz, and even a fully automatic system shouldn't be too hard to qualify; there is a precedent in the Euro ATV.
To be honest the Sammy stuff in my Note is ok. The bugs I see are in the stock Google mail app, and are still there in the latest, latest version.
