Hyundai ix35 Fuel Cell: El Reg on the hydrogen highway

Re: "... there is a dearth of renewable power."

To be fair Iceland has loads of untapped energy production potential, there was talk of a 5TWh a year cable being laid from Iceland to Scotland and onward to mainland Europe:

Re: No pat on the back here

Also if the cabinet is predominantly used by businesses they don't seem interested either. If BT upgraded cabinets used by businesses it would damage their over priced BTNet business.

Data centre disk use is spinning down – Wikibon report

Bob H

In the grand scheme of things most companies don't generate PB of data and capacities are generally more boring than we expect. The idea that capacities would grow exponentially is a little flawed.

Intel left a fascinating security flaw in its chips for 16 years – here's how to exploit it

Bob H

Intel Media Processors

Now I am wondering if any of Intel's CE chips used in pay TV are vulnerable to this exploit. Obviously it depends on the ability to execute privileged code to begin with but that isn't improbable.

OK, who unplugged the modem? North Korea's internet disappeared for four hours today

Safe as houses: CCTV for the masses

I think that the CCTV products on DX.com look good and paired with a Synology they make a good IP CCTV system. Nigel, any chance of adding Synology and ONVIF cameras to your schedule?

UK.gov issues internal 'ditch Oracle NOW' edict to end pricey addiction

Bob H

Re: remotes

To be fair Libre/Open Office isn't as good as MS Office, I've been trying for years to reconcile the issue but it doesn't come out in the wash. I did recently spend two years using mostly Google Docs, it justifies the lack of features because the document collaboration is so immensely good but the formatting and working options aren't nearly as good.

But in contra to my own argument my mother has been using Linux as a desktop for the past few years and is barely concerned that it isn't Windows.

Much noise about cost savings, the departments will ignore it or find ways to show it would be too expensive to change and nothing will happen. Ah the civil service... we do admire your gall.

Giant Facebook SOLAR LASER DRONE to FEED interwebs into YOUR FACE

Bob H

Re: I so torn

You wouldn't/couldn't use optical communications to provide the links to each customer because you'd need thousands of separate beams. The only ground link laser can avoid clouds by relaying through an adjacent drone that isn't blocked by cloud. If the entire geography is blocked then you can always use wireless as a backup to provide resilience.

Mesh networking between them and multiple resilient ground links with a satellite backup?

Bob H

Re: I so torn

They specifically say the lasers are used for interconnection between the drones at 10Gbps, so they are backhaul not the primary link. I think the implications I have seen are that user links would be radio wireless.

Re: I so torn

Is there much in the way of cloud above 40,000 ft? Probably very managable, also remembering that the estimated 3bn people who don't have internet access are generally located around the central belt of the earth and in many of those countries the weather is quite consistent.

Global spy system ECHELON confirmed at last – by leaked Snowden files

Bob H

Re: Menwith Hill Station

To be fair though Mark Thomas is a bit of a knob (not Brian Cox's spelling). He once turned up at JFB Corsham demanding to be let in and shown the secret tunnels under it. A very nice press relations officer came to the gate and said something along the lines of "Mr Thomas, if you put in a formal request we'll gladly take you down there, but you can't just turn up unannounced", he then cried about them hiding things while she responded that they'd happily show him if he'd only get an appointment.

Having visited JFB Corsham myself and having met people who have been down there I see he was making a fuss about nothing. The tunnels under Corsham have been abandoned and neglected for many years since they were a Cold War bolt-hole. Mark Thomas went down in my estimation after that, and I was also unimpressed by his giving detailed instructions on how to attack the UK's strategic fuel pipelines, even if that wasn't a major threat it was inconsiderate.

So what exactly sits behind Google’s Nearline storage service?

Bob H

You could deal with RAID and resilience by writing it in parallel to RAID-0 with extra CRC and then Blu-ray. The RAID-0 gives you the speed you need to complete the medium retrieval times and the Blu-ray gives you (more) assurance that you can recover the data in a failure.

Sydney adopts 'world's first' e-ink parking signs

Bob H

Re: Fantastic!

The article says they are "equipped with mobile broadband", I'm a little surprised at this, I would have thought that zigbee/z-wave or similar would have been lower power or even better some kind of MW carrier because the data requirement is low and the update periods are probably very long.

Who knows, perhaps they update them via SMS!?

Help! Our Virgin Media TiVo boxes are stuck in a loop! Help! Our Virgin..

Bob H

Re: SOP for VM

You can't split satellite antenna signals, each tuner (so two for most PVRs and one for a general receiver) needs an individual connection to the LNB. If you're in adjoining properties all you need is another cable down from the LNB on the front of the dish. I understand that most satellite installers fitting PVRs these days don't bother with dual output LNBs and just fit a quad as standard, so there are generally two spare outputs available for future use (or sharing with the neighbors). I'd also put an earth strap on the cable as well, just in case.

Would be nice if Sora supported the BladeRF, given the presence of the Zinq FPGA that should help.

BT's Openreach plots G.fast end-user trials

I've seen BT skip cabinets that were entirely used by businesses, there must be some interesting threshold that preserves the BT Net fibre business by skipping these cabinets.

I used to be on a cabinet which wasn't upgraded to FTTC despite all the others in the area being so, I swear it was because all the properties it served were businesses and it would have killed the local BT Net fibre business.

GOOGLE GMAIL ATE MY LINUX: Gobbled email enrages Torvalds

Bob H

Re: Finnish Americans don't get irony either

Are you sure he didn't pay for it?

Bob H

Re: Does not compute!

He probably uses it because:

1) Volume - The quantity of general mail he gets and the amount of spam he might get be vast, so he needs something that can handle the GBs of email smoothly. His inbox size could be huge and difficult to not only maintain but search. Bet he doesn't "Inbox Zero" at the end of the day.

2) Conversation View - Yes I know that Thunderbird or other tools do provide conversation view but Thunderbird is increasingly less performant especially on larger mail boxes (in my experience).

3) Spam - This is the controversial part of the mix because it is the bit that failed, but good spam filters are rare.

I spent many years running my own mail server, dealing with spam filters, I've moved to a hosted solution mainly because I can't be bothered with the hassle any more. My IMAP host isn't google which means it is relatively slow and has terrible webmail, but at least I don't have to worry anymore.

Anyone have any suggestions of good value hosted IMAP providers with decent webmail (e.g. Horde IMP not just Squirrel Mail) and configurable spam filters?

Cambridge boffins: STOP the rush to 5G. We just don't need it

Bob H

I've sat on dozens of standards committees for different subjects over the years and almost always the deployment has been a target but it has never stopped roll-out of the previous, well defined, generation. I don't understand why the standardisation of 5G has any effect on 4G roll-out?

I think 5G is just a distraction and shouldn't be used by operators as an excuse for slow roll outs, especially when we are seeing so many software defined base-stations now!

BT: Let us scrap ordinary phone lines. You've all got great internet, right?

Bob H

The landline carries the ADSL we need but the issue is why do we have to pay for the PSTN termination on the end, when all we want is the DSLAM. Yes there is a public safety issue but I have sometimes purchased several DSL lines for a company and you resent paying for the PSTN component you don't use.

There is a obligation on Openreach to supply PSTN with every last-mile circuit, even if the customer doesn't want it and this is clearly costing consumers. If that obligation was removed Openreach would save money because they wouldn't have to maintain termination and interconnect capacity. I have seen one ISP who offers a "no call" discounted line rental but most ISPs acknowledges they would like to drop that obligation.

I think FTTH ONTs provide backup for hours hours or so, so that should cover 99% of outages but here is a letter from BT to Ofcom on the subject:

http://www.btplc.com/thegroup/regulatoryandpublicaffairs/consultativeresponses/ofcom/2011/batterybackup/bbu_response_060911.pdf

I get power outages a couple of times a year but my mobile phone works and even if I have poor coverage. 999 will work because of cross network sharing of emergency services. And for those who are complaining about not getting any broadband or DSL service? That isn't the point of this article so quit your whining and turn off the stuck record.

10 things you need to avoid SNAFUs in your data centre

Bob H

Re: Carry a test meter

I dealt with the kit install at a trade show for my previous employer for several years and each year the electrician was different, one year I actually told the stand build company to send the sparky away and that if I ever saw him again they'd never get the contract again. Apparently the liberal use of multi-way adaptors is a substitute for a decent distribution unit. Fortunately there was a lighting contractor on-site as well and I asked him if he had spare power distribution blocks (he had) and between myself and the lighting guy we made it safe(r). The original cables and adaptors were actually warm to the touch, something I hadn't seen to that degree before and never want to see again!

Re: Arse!

I was once baby sitting a vendor who was doing an install at a client site, as I new I was just supposed to be supervising the vendor I got VERY drunk the night before. The vendor turned up and they had put a UK BS1363 plug instead of a IEC60309 (Caravan) connector! The vendors engineer said she wasn't allowed to change the power connector so the day was a washout, I called my boss, told him and he said "get it done". Fortunately I know what I am doing with electrics but unfortunately I had a royal hangover. Not a problem, I'm just wiring a plug aren't I? It all went well until I was about to flip the breaker and the vendor engineer said to me: "You're pretty hungover, are you sure you wired that right?". My confidence was immediately dealt a blow, but I was too hungover to de-construct the connector again to check, so I just plugged it in and decided to let the breakers deal with the consequences! Luckily I am apparently a good engineer even when hungover and it all worked fine.

I worked for a large European telco, we had a control system (PC) which managed some complex broadcast encoding and multiplex systems. The software was written by the vendor because the customer was huge but the vendor subsequently decided the software wasn't what they needed and they depreciated it. It took several years of using it before we found out, to the cost of the poor Ops Director (covering for the Ops Manager's holiday) who was doing some configuration changes, that if you made any changes on the last Friday of the month it would corrupt the database! Then if you reset the PC it would also reset the attached equipment until the control software was back up, but the database was corrupt so millions of people missed their Friday night TV while the Ops Manager rebuilt the database!

Nice 4G-for-plods demo, Samsung. Good luck actually selling it

Re: ...Replacing GSM-R

Makes me wonder if LTE band 31 at 450MHz might be available in the UK for it, it is only 2 x 2.5MHz, it could be traded. Get whoever wants the old frequencies to do the upgrade then the commercial incentive to get it done quickly and under budget would be there.

Singapore to trial 10Gbps home broadband

Bob H

From the content provider side 8k is only being developed for public display use currently, although I am sure Samsung and Sony will try and sell it to consumers because they want muppets to buy a display they couldn't possibly appreciate with human eyes at reasonable viewing distances. 1080p140 is actually beautiful and more striking to me than 4Kp50, but the marketdroids haven't noticed and are focused on flogging 4K panels.

Huawei announces tiny 10 KB IoT kernel
