Weather Balloons are excempt provided they use standard meterological balloons and the payload has a parachute. In the UK you just need to apply for a permit to launch - which is just to make sure what you are doing is excempt.
The radiosondes are wireless telegraphy act excempt too as long as they radiate less than 10mW. They usually are set to frequencies that are in the 70cm Amateur radio band to increase the number of recievers available for tracking - there is a pretty comphrensive amateur radio network covering most of europe/worldwide that will pick up tracking signals automatically and stick them on a variety of live websutes.
actually it's 4 million if you include those who can get BT sport on Virgin Cable.
I think it was meant as a Joke
but I'm not pretending to be a lawyer so how should I know
Sounds pretty threatening to me.
Last time I was in china (using state run dial-up) the reason I couldn't access many websites sites I wanted to wasn't so much down to outbound firewall rules in China, it was inbound access from Chinese registered IP address being blocked on the sites I was trying to access that was the problem. After decades of malicious attacks, western administrators are pretty wary of Chinese registered IP address ranges.
Quite right - NSA GCHQ MI6 and Special Branch are all in the business of asking people (either nicely or not) to hand over ther keys. The millions of dollars/pounds is not spent on impossible amounts of hardware to crack impossible codes but on the intelligence and manpower to finger the right people to give up the keys.
SSL is an easy one since the cert itself tells you exactly who you need to go to to get the key. Once you've got that you just drop it into wireshark and encrypted data turns into decoded payload - I've done this myself on a couple of occasions (whilst fault finding and with the persmission of the cert owner of course)
I think you may be telling half a story.
| So you can bet the NSA probably has already decrypted them |
they have the clear text already.
The last time I spent about 3 days trying to explain to some middle management type why there was absolutely nothing we could do about parity errors in some of our kit.
That already happens in fact it's pretty much inherent:-
Want to communicate with a submarine on the other side of the planet? No problem - use 16Khz and a missile range to rig up your 40 mile long antenna and you'll penetrate even the deepest ocean - trouble is with a usable bandwidth of less than 100 cycles/sec you'll be limited to about 5 words a minutes in morse code.
Want 10Gbps data transfer across the room? No problem - use a carrier freq of 50Ghz and you'll have oodles of spare bandwidth to give you that throughput and a simple gunn diode will easily give you the amount of power needed to progate 10 feet.
National Lottery seems to work OK and has done since day one - oh hang on, no that's us giving money to prop up a government shortfalls isn't it? So I guess it doesn't count.
Eh? Ethernet is carrier sense multiple access - it's roots lie in ALOHA net - a wireless protocol that linked up sites across the University of Hawaii in the 1970's.
It's more like some loon going up to the White House, knocking on the door and asking for a glass of milk and the guy on the door letting him in and directing him to the oval office. The guy sits around waiting for his milk for an hour or so and finally leaves but not before leaving a note on the president's blotter saying how pissed he was.
The guy on the door, in a lame attempt to keep his job, makes out that the idiot looking for the milk he stupidly let in was some kind of rogue navy seal out to kill the president.
What the US DoD described as the most serious case of computer hacking ever perpetrated comprised of this:
Buying a commercial copy of PCAnywhere (used to remote control PC's) and entering a load of IP addresses allocated to NASA and the US DOD until he found a few boxes running PCAnywhere with no usernames and password's entered.
NASA gate the police the serial number of the copy of PC Anywhere that he used who traced the number of his copy of PC anywhere to his local Dixons/Link shop and then traced it to his Barclay card and arrested him.
Worlds greatest hacker??? They wouldn't have been suspicious if he hadn't left notepad files on the PC's desktop saying stuff like "I've found all them files about aliens you know"
In 2002 it was pretty common to use PCAnywhere for remote support, not putting it behind a firewall or even sticking a basic username and password on should have been a sackable offence really. It would have been laughed out of court - that's why the brits never prosecuted him in the first place.
Sssshh, don't mention the fact that we've got 44.x.x.x all to ourselves.
or they'll all want a piece.
because radio nets work better in relaying information quickly to multiple endpoints. I'm told PTT over cellular is fairly well used in the States, but it never took off in the UK.
They were doing it on purpose to link MAC addresses (universally unique addresses of home and business wireless routers) to GPS co-ordinated. This is so they can guess where you are in the future by looking up the MAC addresses your mobile device can see and checking these against a world wide database - not a bad idea if your GPS coverage is a bit flacky.
Of course they picked up a lot of garbage as well as the MAC addresses they wanted in the spource data, and someone thinks that there's half a chance that the source data still exists (unlikely) and that someone would be arsed to search through it for anything other than the address data (verging on the paranoid delusional).
It's all about encryption, or rather making comms secure from evesdroppers. If someone intercepts the communication then the transmission is lost. It's the holy grail in secure comms.
Some dick was hacking about with the code and fucked up.
Get's on my goat being an old foggy who actually remembers what these terms actually used to mean before the l33t generation got hold of them.
Cisco blamed it on space weather - a stray cosmic ray flipped one of the bits.
Catastophe was avoided, however, as we had a second ACE in standby and all the sessions flipped over while the primary one rebooted.
that's your problem there.
Everything else is a non-story.
the better ;-)
PACS, Cerner Milleniom Acute and Rio Community and Mental Health applications to the majority of trusts in London and the South of England and I don't see them going to the wall.
Maybe it's just economies of scale - presumably BT has plenty of high capacity data centres piped in and ready to go.
The light is encoded with an electronic signature.
they have sligthly different legal system in Greece and looking people up on Google may figure quite importantly in it.
He puts a note through the letter box to tell me it's in there.
This did require me to actually talk to the guy and ask him to do it - something the on-line guys seem to have forgotton how to do.
Last time I worked there, the comms rooms were on the higher floors. There was a tunnel which lead between the two buildings where some of the cabling went, that was in the basement. Oh and the rifle range of course, oh and the olymic size (less 2 inches) swimming pool in the basement, that's all.
The data centre(s) now they were a different matter. Even the locals didn't know where they were or what they did. Same with most data centres I've worked in - well away from any threat of disaster and running in tandem with others just on the off chance. You don't see them on any maps.

Hasn't moved for 20 mins, maybe it's in the queue at the check-in desk.
Why do that when you could upgrade to their new improved even bigger carrier class routers to grunt all that video at wirespeed.
Ooops cat out of bag
