Scotland

The maximum ever outside air temperatures in large parts (if not all) of Scotland are well below the maximum inlet air temperatures required by modern equipment, and an awful lot closer than Scandinavia or Iceland.

Like they say we like summer in Scotland it's our favourite day of the year.

Putin's Russia outlaws ECHR judgments after mass surveillance case

jabuzz

Re: Before we get too judgemental...

What's the EU got to do with the ECHR, apart from nothing? Admittedly UKIP want to withdraw from the ECHR as well as leave the EU, but that is different from Russia who has not withdrawn from the ECHR but said we can ignore it's rulings if we want.

ECHR = European Convention on Human Rights and has nothing whatsoever to do with the EU

EU = European Union, the renamed EEC or European Economic Community that has in it's found document that we voted on in 1974 "towards an ever closer economic and political union". I would further note that Sir Winston Churchill was all in favour of a United States of Europe as early as 1946.

Brocade admins: Check your privilege

jabuzz

Re: Fabric OS v6.3.1b is very old

Not only is FabOS 6.3.1b ancient, but anyone running a fibre channel fabric and who does not have access to the management ethernet ports on a separate "management" network where access is highly restricted deserves what they get anyway. That is if someone who is not in a position of trust to have full admin rights over the switch can even so much as access the switch to ping it on the network port then you have failed to begin with.

GPS, you've gone too far this time

jabuzz

"You're getting confused with something called Selective Availability which was switched off years ago."

Er I think you will find that you are wrong. While Selective Availability is turned off, without access to US military specification GPS units you won't have access to the encrypted P code stream only the C/A code for civilian operation. This is something completely different to Selective Availability and gives the military specification units higher precision than civilian units can achieve without the use of an accuracy enhancement system such as DGPS.

Boffins teach Wi-Fi routers to dance to the same tune

Re: Clock signals

Actually very few countries have clock signals. While most of them are based on amplitude modulated LW, some are based on alternative techniques, these include the French TDF, the Rusian RBU. Of the amplitude modulated only MSF, JJY60 and WWVB share a frequency of 60kHz the 77.5kHz of DCF77 is also shared with BSF. This is important because the cheap receivers all used pre-tuned ferrite rod antennas, so even if you equip your WiFi hotspot with both 60kHz and 77.5kHz antennas it will be useless in northern Japan where you need a 40kHz antenna for JJY40. It will also be useless in China which you need a 68.5kHz antenna for BPC. The Russian RBU uses frequency modulation of the pulse which will require another completely different circuit for, and the French TDF uses phase modulate of the TDF radio station signal to encode the bits, which would also require a completely different circuit design.

There are no LW radio stations in South America, Africa, or Australia. There are SW radio time signals but these require much more expensive circuits to receive. Further complicating matters is the fact that many of these time signals are not broadcast 24/7 either.

I think people in Europe and North America tend to forget how fortunate they are to have reliable LW time signals.

Reg lecture asks what’s so scary about 1.5 tonnes of metal with a mind of its own?

Re: Oh really?

You step out onto the road in the path of an oncoming vehicle and you are not a pedestrian crossing giving you right of way at that point in time then you are to blame. Why would it be any different to the current situation?

Also all teh very *COMMON* scenarios are easy to think up and program rules into the system to deal with. That just leaves the uncommon scenarios, but remember the self driving car only needs to be better than the *AVERAGE* driver to reduce accidents and deaths on the road. I know most people, men especially think they are all the Stig, but the reality is quite different.

Top telematics: Black box helps driver swerve speeding fine

jabuzz

Re: Didn't work for me :(

Golden rule of driving is to be able to stop in the distance you see to be clear ahead. So unless the Police car overtook you or pulled out from a side road into your clear space and then broke you where in the wrong if you needed to overtake him for any reason. In effect you got off on a technicality and the initial conviction was correct.

Note this golden rule of driving might mean that you need to slow down to go round a bend, not because your car is unable to make the bend at the speed, but because the bend reduces the visible road ahead that you can see to be clear.

Don't want to fork out for NAND flash? You're not alone. Disk still rules

jabuzz

Re: Give it time

Consumer drives account for a small fraction of the shipped used capacity. My educated guess is most capacity is going in the data centre or at the very least consumer level NAS drives, for which SSD makes no economic sense. So unless there is a huge drop in the cost per GB of SSD's disk is not going anywhere. It's just like tape, need to back up 500TB, well doing that to D2D is just not economic even with dedupe.

So while spinning disks (there has been no spinning iron in disks for decades) may well disappear from end user equipment, and 10k/15k RPM hard drives are on the chopping block, the bulk storage 4TB+ 7200/5400 drives are going nowhere fast. I have a pair of 4TB 7200 RPM drives in a RAID1 and it happily could do six different simultaneous 720p streams from my Plex server. At that point I ran out of playback devices, in these sorts of applications SSD is not replacing HDD any time soon.

Bezos battery-box bomb beef brouhaha begins as UK watchdog hauls Amazon to court

jabuzz

Re: Coincidentally...

A CRT will never be bio-hazardous waste. That is a term reserved for biological based material that is potentially hazardous, think hospital waste or material from bioscience laboratories.

On the other hand a CRT is full of heavy metals (lead in particular) and is therefore hazardous waste. That said the recovery of the lead from a CRT makes it a roughly cost neutral process, aka the value of the recovered lead is about the same as the cost of recovery.

Note that putting any electronic waste into general landfill has been illegal in the UK for quite a few years now.

BBC joins war against Flash, launches beta HTML5 iPlayer

Re: get_iplayer

get_iplayer pretends to be a flash player using rtmpdump. If you read the blog article on the BBC website then you will see they intend to still serve to flash based devices for a few years yet. What happens then is another matter of course. Hopefully get_iplayer will be able to switch to HTML5 before then.

PatchSee

Sorry but you can just follow the cable afterwards if it is a PatchSee network cable. You put the handy tool thing over the cable and vola the other end is illuminated making identification easy peasy. They also come in lengths from 60cm to 3.1m in 30cm increments all with the length printed on the plug. So no excess cable, and no guessing on the length when reusing the cable.

Sierra Nevada snow hasn't been this bad since 1500AD

jabuzz

Re: They could solve the drought...

That's not going to end the drought however. That is no more water is going to fall from the sjy even if every last almond tree in California was chopped down tomorrow. The result is at a minimum that ski resorts in the Sierra Nevada mountains will still be impacted. That is assuming the drought does not end this winter, which seems unlikely.

It is fully blown DRM it is the same scheme that is used by DVD-Audio, which Wikipedia tells me has been broken. However given that CSS in DVD's has been broken, AACS in Bluerays is at least circumventable, and HDCP is smashed into very tiny pieces it is all rather moot.

Re: not DNS, but routing issues

I can add that it was definitely a routing issue and not DNS, and it was random. So a connection in Scotland on Plusnet with its own private DNS server worked fine. A similar server in England did not, some but not all DNS lookups where failing. A random Plusnet connection down the road in the next village from the one in England also had partial DNS failures.

Re: List of supported channels/services

But if all you want is the UK catchup services, then a NowTV box is far better value than anything else. They seem to be out of stock of the £10 ones, but you can get one for £20 with a 3 month entertainment pass, and then flog the pass on eBay for a tenner. Best bit is you are getting Mr. Murdock to in effect give you money because Sky are subsidizing the box. Even better you can side load the Plex or Emby (aka mediabrowser) client onto the box.

Cyber-scum deface Nazi concentration camp memorial website

Re: Que?

Er go check you facts. The vast majority of slaves transported from Africa (we are talking 99.999% and upwards type figures) where rounded up *BY* Africans for sale to the slave traders. Anyone who thinks Europeans sailed up to the African coast jumped out and rounded up people to ship over the Atlantic is a deluded idiot. Africans were UTTERLY complicit in the slave trade, and without their participation it would not have been possible. When in 1807, the UK Parliament passed the Bill that abolished the trading of slaves. The King of Bonny (now in Nigeria) was horrified at the conclusion of the practice saying

We think this trade must go on. That is the verdict of our oracle and the priests. They say that your country, however great, can never stop a trade ordained by God himself.

http://en.wikipedia.org/wiki/Atlantic_slave_trade#African_participation_in_the_slave_trade

In short no side in the slave trade is without blame.

Scot Nationalists' march on Westminster may be GOOD for UK IT

jabuzz

50% of a 77% turnout is 35%. The number of votes cast for the SNP in the election was about the same as those that voted Yes in the independence referendum, and that was *BEFORE* the collapse in the Oil price.

Personally if I was David Cameron I would ram fiscal independence down Sturgeons neck. I would have it coming into full force in April 2017, which is slower than Salmond wanted, because he was going for *FULL* independence in May 2016. When faced with the reality of devastating cuts to public spending and/or massive tax rises that fiscal independence would bring the SNP might just not do as well next May. Of course if the SNP did not win next May you could back peddle on it :-)

Business taxes is the difficult one, we know the SNP plan is to have a lower rate than England so they can leach taxes from England by getting multinational corporations to relocate their headquarters to Scotland. Two solutions to that in my view, the simpler one is just match anything the SNP do and play a game of chicken that Scotland will loose. The more complex one is say force companies with a profit over say £1m to make up the difference lower Scottish taxes based on percentage of turnover generated in the rest of the UK removing the benefit of a multinational relocating to Scotland to avoid tax and sinking the SNP's taxes plans before they get out of harbour.

The other thing I would do is ram another independence referendum down the SNP's throat. When the loose for a second time they are going to have a hard time calling a third for decades, by which time there should be no oil left and their economic plans will be in complete tatters.

SCREW YOU, BRITS: We're going through with UK independence ANYWAY – Scotland

jabuzz

"As the older more conservative voters fade away, and as SNP support continues to climb, a new referendum is inevitable, just a question of when."

As a No voter I would like to see another referendum this year, I suggest September the 17th. This time we can put to bed the total and outright blatant lies that where the economic policy of the SNP. Unfortunately there won't be one for a generation by which time the closet Tory "I' all right Jack, we have oil now sod you." policy of the SNP will be dead and buried as there will be very little oil left.

Had there been a Yes vote Scotland would now be staring down the barrel of economic ruin. The SNP's calms of prosperity where all based on a price of ~$100 a barrel for oil. Now at half that there would be a massive black hole in the Scottish government's finances that would only be pluggable with massive unsustainable borrowing or austerity that would make the current round pale into insignificance.

It would have been the Darien Scheme all over again.

Re: "Broadcast is efficient"

Assuming your broadband connection is up to it, the BBC iPlayer HD stream is 720p as can easily be ascertained by using get_iplayer to download a stream to disk and examining it to your hearts content. So in reply the BBC iPlayer HD stream is better than an SD broadcast.

The live sport consuming massive amounts of bandwidth is entirely fixable with multicast and BT Openreach offer this facility across large portions of their network in a product known as Multicast for Generic Ethernet Access.

Plusnet could face DATA BREACH probe over SPAM HELL gripes

jabuzz

Re: How big a problem and why?

Yes I would because it is a very specific form of spam that they are complaining about and I don't have any matching spam in my inbox or anywhere on three PlusNet accounts that I have checked.

So the question is if said database has been breached why has the spam not been delivered to the none PlusNet email addresses for these three accounts?

My Occam's razor is at this point telling me the spammer got them from somewhere else.

No NAND's land: Flash will NOT take over the data centre

Re: "what comes after is breathing heavily down the neck of flash"

Plusnet customers SWAMPED by spam but BT-owned ISP dismisses data breach claims

jabuzz

Re: no proof

Sorry but you can setup your email at PlusNet so that all email to *@myid.plus.com gets delivered. It is one of the features of their system and has been like that since well longer than I care to remember certainly more than an decade. That said I have the wildcard address directed to /dev/null another very long standing feature, though I can remember a time when it was not.

The amount of spam I get on my PlusNet hosted email account is very limited ever since they included virus and spam filtering by default rather than an optional extra. I have personally not received the spam in question, and one would presume that if the PlusNet database had been compromised that the spammer would have spammed all the addresses harvested not just some.

That last bit suggests to me that the spammer has managed to harvest the email address from somewhere else. Where and how is the question.

Why can't a mobile be more like a cordless kettle?

jabuzz

You aready can

A "cordless" kettle has to be placed on a special base. Funny because I can simply drop my Z1 Compact onto a special base just the same. In fact "charging bases" exist for the whole Xperia Z line up. In the past I had something similar for a Nokia 6310i. So to answer your question mobile phones can be more like a cordless kettle, that yours is not is down to the choice you made when you purchased the device, just like you can still buy corded kettles.
