Yeah; about that - at the beginning it says buying airtime on. That's not the same as buying the bird; the same way I don't own an A320 after buying a ticket on easyjet.

I'd heard that Virgin were increasing their monthly charges, but £4.5m to watch a football match? No wonder people are leaving in their droves.
Re: Throttling exists
Well, in my case I have a Virgin UK SIM and a Spanish Voda SIM. When I use the Voda SIM in the UK, it struggles to even get 3G, whereas in Spain it gets 4G, and puts the Virgin broadband to shame! The Virgin SIM sends to get equal service at both ends.
Note that this isn't the second Sentinel satellite. However, it is the 2nd Sentinel 2. There are also 2 Sentinel 1s (1A and 1B), and there is a Sentinel 3A already in orbit. Sentinel 2C is currently in manufacture as well. The Sentinel 4s are due to go up with MTG-S, so are still a few years off, and Sentinel 5 will go up even later on Metop (although they'll be a Sentinel 5-precursor to start getting data sooner). Sentinel 6 will be the new Jason in combination with the NASA.
Re: ExoMars...as the mission starts to slow down.
Nope; you slow down. Imagine that you swing a weight on a string around you. As you go slower, the circles are smaller, and as you go faster, the circles are larger. It's not exactly for the same reason, but the visualisation may help.
Note that speed up and slow down here refer to the speed of the object; not the time per orbit.
Re: "and will try turning them on then off again over time"
I tend to think that the 1 year lifetime is to allow for really pessimistic dependability/reliability analysis. Also you look good when it lasts much longer than expected. If you sell it as a 10 year mission, but only make it to 8, you look like a failure.
Re: Different approach to it
Yeah, but they're now telling me too design out the TO-5 relays. There have been a number of other, erm, happenings, so someone is going off them.
As for crazy phone calls about why you want to use an LM139 compartor designed in 1960, who are you? and list every single person who will work on it, and every address the unit will ever be at, and...
I don't know many details of the Space-X system, but I read elsewhere that the error possibly came from bad GPS value or calculation. Typically, medium range docking uses a sort of Differential GPS to compute relative distance and velocity. Possibly the distance and/or velocity suddenly changed by an amount outside of expected values.
In an earlier failure report that I read for Dragon, it said that the system failed from a Single Event Effect; some particle of radiation corrupted a value or signal, causing the system to trip. Normally critical space systems are designed to be immune to these types of event.
Re: "generate 'abnormal' quantities of traffic"
"The impact on the user is, essentially, fill in a CAPTCHA to prove you're actually human. Then Google leaves you in peace to get on with it."
No, it does the search and then when you change it slightly, or horror want to see page 2 throws another captcha at you. Sems to happen continually if you use any of the search parameters (filetype, inurl, etc.)
I would like to think that the Google bot is cleverer, but my experience with Google search results suggests otherwise. Whatever happened to the planned Chrome feature where I could flag websites as SEO spam and never see then in search results again?
@Electron; yes; but there are still some programs that don't work properly without higher acres permissions.
@Doc; my account has the privileges to edit my files - that doesn't mean that I want someone pwning my system and stealing/editing/deleting them, even if they still don't have permissions to do admin stuff.
Re: Obligatory Film References
That's no asteroid - that's a ship
and the reason that it's so bright is that the death star isn't finished yet and the workers have left all the site lighting turned on.
So what would happen if they thought that the potential legal action might have an impact on their year end accounts? Would they have to file a report with the securities exchange committee saying "After we found a security hole in XXXXs application and informed them and offered to help, they threatened us with legal action, which may be a risk for our year end accounts".
Obviously they haven't done anything wrong! If there wasn't the threat of legal action, they wouldn't have had to do it, and the bug could have remained undisclosed while it was being fixed. Instead, at least it's existence would have to be disclosed instantly.
Re: Weight a minute
Just for a giggle, read the SpaceNews.com article (American) which gives the mass of supplies in kg :)
Re: Time for a bit of renovation?
Well you'd then end up with no way to keep the station boosted, so it would then re-enter. And the Russians said about separating their modules because the other partners were talking about cancelling the ISS and de-orbiting it. (especially since some are newish, and not even up there yet). I would think that they'd be more than happy to make some money from the ISS, given that their major source of cash, oil, currently sells for less than it costs then to get it out of the ground.
Re: Why is this the only thing we care about?
"Other than Mars, the only other chance for finding life* seems to be outside the solar system..."
Well there are some indications that the moons on the gas giants could also harbour life, especially the icy moons of Jupiter - Hence the JUpier ICy moons Explorer project (JUICE). Now that project is really pushing the space engineers (the rocket scientists not so much); very remote, hardly any power from the solar arrays, eclipses that put other eclispses to shame many times over, radiation levels that literally cook the electronics...
Re: Consumer benefits are not falling!
"It's not about cutting off the power (none of the meters have the 100A contactor required)."
The meter I've had installed in Madrid (Sagemcom CX2000-9) has a latching relay that turns off the supply either based on the actions of the supplier, or if my consumption goes over 8A on any of the 3 phases. The 8A limit is something that I can choose to change, by paying a fee and then higher standing charge (demand management!). It does "remember" that you were cut off after a power cut too.
I don't know what they are fitting in the UK, but if one meter has it, I don't know why another couldn't.
"They can in theory disconnect your services without a smart meter."
As long as you let them in to do it, or they get a court order and use the local police to make entry, and then someone "skilled" disconnects you. With a new meter, someone in a call centre (or a software auto script) clicks a box on a Web form.
Re: How space-junk-proof is it?
Since windows aren't very flexible, they have to dissipate all the energy of the said paint flec, almost workout moving (or move and break). Since the fabric of this is flexible, there is an opportunity to deform slightly without breaking. Comparte what a car body panel does, compared to a bullet-proof vest.
International Space University
As I understand it, international space is above an altitude of 100km. Unfortunately I will be visiting a much lower altitude on the day of the event (for a pre-launch equipment resupply inspection), but far from London, which doesn't have convenient launch facilities. Will it be possible to visit the university in person instead at another time? I will be in orbit 2 weeks before or 1 week after the published date.
Re: What chance ordinary users to stay safe?
Just out of curiosity, how does this OS verify all code before execution? Maybe ban it if it sends data to the Internet? Maybe block anything that reads from the memory card? Takes a foto? Uses the microphone to listen? How do you tell unwanted from wanted?
It depends on the mission, but there is normally a "safe mode" which can be triggered for a number of reasons, for example the battery rings very low, it's spinning too fast, it's lost lock on the Earth, etc.
Often the safe mode will do a hardware reconfiguration, which is like an interrupt, and physically switch over to a different software bank and run specific software to recover the space craft, stabilise it, orient the solar array to the sun and point comms antennas at the earth (all depending on the spacecraft and orbit of course).
However if the spacecraft is spinning because of a fuel leakage, it may not have the capability to control it's attitude anymore. For all the "miraculous" recoveries (and some of the failure reports show amazing ingenuity) there are a number of spacecraft that never recover. I'm crossing my fingers.
If you want to build a rocket without anyone knowing about it, what's wrong with underground? Quite a few of the Russian launches I've seen actually came out of holes in the ground. Of course, as son as it launches everyone within miles knows about it, but that's another issue.
Re: too late ?
As I understand it, your gravitational waves come in different frequencies (a bit like light). Lisa is designed to detect ones that you couldn't possibly detect on Earth with any set up - LIGO is designed to detect others, and will almost certainly see some before Lisa will be operational. It's a bit like asking if we need satellites to study the sun in ultraviolet light, because you only have to look up and you can see that the sun is there.
Note: What I've said may have some minor errors - I don't know too much about the payload side.
Re: Automated Press Release Machine
"... does anyone have an XX they're willing to let us rebrand?"
I'm not sure if this is sarcasm or serious.You know that they were already selling a 3D printer that was just a rebadged Stratasys about 5 years ago? Then they decided that like to do better by themselves. Also not sure how their professional printing R&D is these days, but 5 years ago it was OK.
Re: I saw this earlier today
Careful. When Mrs. Bachelor bought me my Note 4, she looked at the Note 3 (she had one I bought her), and was trying to work out why it was soooo much cheaper than the Note 4. Turns out that there is now a cut-down Note 3. It has less RAM, slower processor and a few other things missing.
As for the Note 5 - Samsung have said that they won't release it in Europe, (I guess they want people to buy the big boy I Phone instead? ). Given what happened with region locks on the Note 3 and Note 4 which means that ours didn't work on a trip to Japan, I wouldn't want to buy a non-European one and find that it doesn't work in Europe.
I once worked on an air crash investigation where a plane overshot a runaway on landing. There was a huge fire, and we got our box back with a request to read out any fault codes and calibration data that are stored internally in flash. Basically there was nothing left of the PCBS, except a pile of fibre glass strands and a birds nest of the copper PCB traces. Also the flash devices were in MIL ceramic packages. These packages have a ceramic lid and base, and are "glued" together and sealed with glass. Well, the glass had melted, and the ceramic top and bottom of the packages had come off.
Long story short, the manufacturer of the flash chips read the data out of the bare die no problems. I think you need more than 125°C to ensure their destruction.
Re: Where are they shopping
The vendor is not allowed to store the CV2, which means that they can only take it if they bill you that second. However they are not allowed to bill you until they actually supply the goods or service (in the UK). Anyone who tales an order and then seems it later cannot officially use the CV2.
I'd be more upset that they've created a new system that has EXACTLY the same, known flaw as the last one, which is that it always uses the same number for every single transaction. Was it designe by someone more stupid than Homer Simpson?
Re: The other reason?
"Also I'd heard that cheating was one of the reasons for the popularity of dual-SIM phones in China. "
Yeah, but that's the networks complaining that their marks were cheating on them by using another network.
Re: Why is the left edge of the atmosphere different from the right?
Looking at the high res on the monitor I have here, it seems to have pretty much the same sharpness both sides, however the left side seems to have a blue outline. Possibly is chromatic distortion. When you get this, it tends to show as e.g. green fringe on one side, and magenta on the other (or yellow/blue or something else, depending on the processing)
Re: If you're interested...
Which space junk are you talking about? As far as I know, all old expired satellites have been moved off the Langrange points at the ends of their missions. (e.g. WMAP, Planck, Herschel....too many more to remember)
Re: I've wondered about this every time they have had to dive into the lifeboat....
It's a much smaller target, and can detach in seconds and return to Earth without needing any pre-planning, in the event that the ISS suffered serious damage. In terms of debris proof, it would be practically impossible - there are all sorts of things up there in all sports of orbits that could intersect with huge amounts of energy.
By any account, the attack was one of the worst in history
So in the same press release, did they say how many people's details were spied on by the NSA? was it less than this, or was it something like 98% of the people who use the Internet?
I'd like to say FUCKING HYPOCRITES but somehow that feels too soft.
Yes, very disturbing. It should have been "my mother and I ..."
Re: It just boggles the mind!
and once they worked out what the shuttle was really like, the ONLY thing it was allowed to be used for was to take up huge ISS sections that couldn't be taken up any other way (and one Hubble servicing mission). It was absolutely FORBIDDEN to use the shuttle for crew rotation or supply missions because it was by then it was known just how dangerous it was.
Re: Three to Seven other competitors
I think that this system is supposed to fit in between the mobile handsets and KaSat. What I have seen suggests that you don't need a fixed dish and license to be a user, in fact a number of the antennas will be mobile on vehicles, etc. This is a major plus - using something like KaSat on a mobile basis seems to be very difficult.
Also I don't think O3b really competes with this, since you need 2 dishes, each of which is tracking a bird across the sky, one after another. For backhall or village ISP, O3b could be useful, but for a single user (especially with little space for dishes, or mobile use) I don't think so.
As far as capacity is concerned, if your options are this or dial-up, or you want access when infrastructure is down, and in a mobile context, then it could work. We'll only know when it flies, or crashes and burns.
Re: Remember Iridium?
I also heard that they had big problems getting permission in each country to use the particular frequency band they had. By the time they had negotiated enough rights, the cellular networks had rolled out and there was less need for Iridium. Also the data access is still only at the same speed that I had with a Nokia 9000 over 15 years ago, so their unique selling points are very weak.
I assume (hope) that oneweb will know all this, and have a better handle on things.
Re: Over engineered?
I'm not going to dig out the specs, but they will say something like "Must have a reliability better than 0.9 for the primary mission phase 1, and better than 0.85 for extended mission phase 2". The primary mission will include 1 year on ground testing, launch, 10 years in space with nasty radiation and horrible temperature changes, separation from Rosetta, landing, and then 60 hours operation on the surface". Extended mission phase 2 probably is something like 1-2 months, but with higher temperatures, and after doing some stressful things.
Now, if the reliability is 0.9, including the 10 years travel time, tell me what is the probability that it suddenly dies in the next 7 months?
" the bulletin is only rated "important" as the user would need to manually open a maliciously crafted Office file"

Can't they just list all vulnerabilities as unimportant because if you don't switch the PC on....
Maybe I'm the only one, but please stop this. I have to travel to places that either just block HTTPS outright, or they do a man in the middle so that they can scan everything on the way through. More common is just blocking it. I know this because of all the problems I had with Google always changing http://www.google.co.uk/ to HTTPS and then failing.
Re: If it was truly firmware?
It they made the memory write once, it would also solve those nasty questions about SMART parameters and the number of bad blocks - All the SMART would say perfect health and there would be no bad blocks - ever.
Sarcasm aside, the firmware needs some space to write stuff in non-volatile memory that isn't the disk, and it's certainly better to put one chip than 2. I've also seen disks that appear to store some of the disk firmware actually on the disk. A bit like the old days, when you enter the bootloader by hand, that then reads code from the paper tape, which becomes the OS, and then you can start loading programs.
Re: It was his own fault
So when he sticks his finger into the running belt of his car engine, you'll tell us that cars shouldn't be allowed near people either?
Perhaps he should have just been wearing the correct Personal Protective Equipment to keep his fingers out of harm's way? A straight jacket?
Re: .sucks sucks, but not for those reasons.
No. They'd put up a page that "lists all the people who have been affected" by Crappy-big-TV company, with an option for other people to add to the list. BUT - there would only appear 3 or 4 people on the list and their claims would be like "The TV is great, but the cardboard box it came in had fuzzy printing".
Anyone going to the site will think that maybe Crappy-big-TV company must actually be good with so few complaints, and the complaints all being minor.
Not on mine. Time for a new phone?
Does it auto download all attachments and run them for all any any dodgy emails too, just to be helpful?
No effective competition
What she said doesn't make any sense, since there is effectively no competition in this market. Many households have no FTTH available, and almost none have more than one. E.g. Telefónica can charge what they want; it doesn't matter what Vodafone might charge, if the fibre to your house isn't Vodafone; you pay Telefonica's asking price, or you go without.
Sorry for the delay. Roscos mos data shows that the oxidiseer tank deprurised, followed by the propellant tank . Also sorry for y h e typing. On a 3 hour journey by truck on unpaved roads :(
Current theory is that separation happened early. It seems that it wasn't due to a pyro being fired at the wrong time either. It appears that it was caused by the tanks of the upper stage rupturing.
They have no problem with coming back, but there is no point bringing them back now, and having the station only half-staffed. Also the Dragon may survive re-entry, but since it has no life support (or seats) it wouldn't make for a good experience!
I read that they wanted to swap the next crew launch with the next progress supply mission to have more confidence before putting astronauts on the rocket. When the next crew launch is set up, the retiring crew can come back.
Re: Tell it to ...

Re: Not a burden?
The problem with this is what exactly are you selling? Let's narrow it down to "a film". Now depending on the media, or digital or not, it could be in a different class depending on the country. Now add in if it is "culturally important" - again the class changes (Note that culturally important in one country may not be in another). Continue listing all the parameters you need to work out the tax class for every country.
So to sell your 2€ DVD, you enter into your software the following:
Item: Film, Colour, with sound, format DVD, Produced in France, Culturally significant in Elbonia, .....
Do you see where this is going? Have a headache yet? It is a complete nightmare to do properly.
