Sony Pictures Computer Sytems Shut Down After Ransomware Hack

jabuzz Re:Dear Sony, I am delighted! (154 comments)

Clearly you don't have young children or have ever seen them handling DVD's and/or Blu-ray disks. It is a lot cheaper to give them a copy of random Disney/Pixar film which can be cheaply replaced than the original which cannot.

Coal Plants Get New Lease On Life With Natural Gas

jabuzz Gas not less CO2 on refiring coal plants (142 comments)

Natural gas is better if you use a combined cycle gas turbine plant, where the natural gas is burnt in a what amounts to a jet engine and then the exhaust is used to heat water for steam turbines.

If you just replace coal with natural gas in the same plant to heat the water it is not significantly less CO2, though it will likely be less other pollutants.

Does Being First Still Matter In America?

jabuzz Re:Amazon Elastic Cloud? (246 comments)

I think you will find that Infiniband is not really up to the task, which might by why the Met Offices new computer is a CrayXC40 which uses a proprietary interconnect called 'Aries'.

Basically while Infiniband is fast and low latency for really big models it is not fast enough and the latency is too high.

Don't get me wrong Infiniband is good, it is just the always good enough.

Military Laser/Radio Tech Proposed As Alternative To Laying Costly Fiber Cable

jabuzz Re:whoosh! (150 comments)

No you missed your physics classes.

Increasing the power and repeating will make no difference whatsoever. If there is no "line of sight" then laser transmission without an optical wave guide (aka a fibre optic cable) is a none starter.

For the purposes of free air laser transmission light only travels in straight lines. That is no gravitational lensing, and no fancy ultra modern optics which basically are of no use in this scenario.

So repeat after me you idiot no line of sight no transmission.

Military Laser/Radio Tech Proposed As Alternative To Laying Costly Fiber Cable

jabuzz Re:cheaper perhaps (150 comments)

Personally I would offer to dig the trench for them, and/or offer them whatever bribes necessary to get it done faster, keep the workers happy etc. Of course that is because I would love a fibre connection to my house even though I have a 40/20Mbps FTTC install.

I would also note that in the U.K. an 8 foot or 2.4m deep trench would be below the level of 99% of foundations and be completely unnecessary. The cable TV networks (now almost all owned by Virgin Media) only were only a couple feet deep when installed back in the 1990's.

Also in the UK that would only be necessary on properties that did not already have ducting for telephone and even then BT are trialling steel reinforced fibre optic cable so you can use drops from telegraph poles where the existing telephone cable enters the property using that method.

Military Laser/Radio Tech Proposed As Alternative To Laying Costly Fiber Cable

jabuzz Re:cheaper perhaps (150 comments)

Oh my god. Really lasers require line of sight because unless you have very special optics going on light *ONLY* travels in straight lines. I mean this is physics 101 for crying out loud.

Sweden Considers Adding "Sexism" Ratings To Video Games

jabuzz Re:What about the male stereotypes? (641 comments)

Yeah Elsa in that aforementioned Frozen. I would add that in my random sampling (aka my nieces) and the speed at which Elsa merchandising sells out young children (probably mostly girls) are way more into the totally uninterested in men Elsa than Anna.

Sweden Considers Adding "Sexism" Ratings To Video Games

jabuzz Re:What about the male stereotypes? (641 comments)

Princess Elsa. Tick for Princess (though I admit she does become a queen in the movie), Tick for Disney. Please find one single second in Frozen when Elsa is even interested in a man let alone mindlessly chasing one. So the all of them fails and I only had to think about it for like 30 seconds.

Denmark Faces a Tricky Transition To 100 Percent Renewable Energy

jabuzz Re:Real problems, but there are also solutions (488 comments)

Really in 2011 of the 128TWh of power produce in Norway 122TWh came from hydroelectric and 1.3TWh from wind. It is a net exporter of electricity with domestic demand only 114TWh.

Because hyrdoelectric can respond to demand very easily and fast, Norway tends to import electric during the night when it is cheap and export during the day when you get a better price.

Really I though everyone knew that Norway was into hydroelectric in a major way.

25th Anniversary: When the Berlin Wall Fell

jabuzz Re:Reminder of who not to credit (151 comments)

The is probably because the Germans having lost WWII have no choice in the matter and various treaties provide for American and British bases in Germany so long as we choose to maintain them.

I know the British Forces Germany have been slowly drawing down since the end of the cold ware and have plans to be gone my 2019 However in light of the maniac that is Putin that is looking increasingly unwise.

Amazon's Luxembourg Tax Deals

jabuzz Re:How is this different? (200 comments)

The reason the EU are targeting Amazon at this time is that they are making the case that the "special tax rates" that the Luxembourg state gave to Amazon constituted illegal state aid. That is the EU has tough rules on governments handing out money to companies to stop a race to the bottom. So it is not that Luxembourg has low tax rates but that they cut Amazon a special rate.

Likely outcome is that Amazon will have large back taxes to pay to the Luxembourg government, and the EU will then impose a fine on the Luxembourg government that is equal or slightly higher than those back taxes for breaking the rules.

In related news the Irish government has unilaterally (they jumped before being pushed) announced that a company based in Ireland will in future have to pay takes on all the profits pushed through that subsidiary. Unlike the current position where only profits directly generated in Ireland where taxed. So Microsoft in future wont be able to sell all their software in the EU from Ireland but only pay tax on the profit from the copies sold in Ireland.

Buying Goods To Make Nuclear Weapons On eBay, Alibaba, and Other Platforms

jabuzz Re:If so damn many people are making nukes (260 comments)

I thought PCB's where etched with Ferric Chloride which in the U.K. at least is readily available. You could walk into a Maplin store and pay cash and walk out with the stuff. Though it is listed as over 18 only. There are numerous sellers on eBay.

The Great IT Hiring He-Said / She-Said

jabuzz Re:Poaching (574 comments)

Thing is being fired for lying on your CV or in interview is rarer than hen's teeth. I have two siblings who have or still work in employment law in the U.K. Neither has ever come across such a case ever. One of them sits as an employment tribunal judge as well.

As for what is said in an interview it will be he said, she said and vrey hard to prove. Personally I have come to the conclusion that other candidates are telling big fat lies in interviews and I am loosing interviews/jobs as a result of my honesty. My sister an ex employment lawyer has told me flat out that I am too honest and need to tell lies in interview. Go figure.

Scotland Builds Power Farms of the Future Under the Sea

jabuzz Re:This article needs fact checking (216 comments)

Except in the UK the typical coal plant is in the >1000MW range. A quick check on Wikipedia and I can only see Carrington B at 860MW, Estong Grange at 800MW, Lynemouth at 420MW (it powers an aluminium smelter exclusively) and Rugeley B at 1000MW at 1000MW or lower power.

The remaining coal power stations are generally significantly bigger
so Drax at just shy of 4000MW, Longannet at 2400MW, Cottam at 2000MW, Eggboruogh at 1960MW, Ferrybridge C at 2000MW, Fiddlers Ferry at 1989MW, Ratcliffe-on-Soar at 2021MW .

Stop putting USA numbers onto a UK report. Just re-enforces the stereo type the rest of the world has that all Americans are parochial twits.

For what it's worth putting turbines in the Pentland Firth tidal stream is as stupid idea. Much better to build a dyke (it's only ~10 miles wide) and extract more energy.

Space Tourism Isn't Worth Dying For

jabuzz Re:Let's put this into perspective (594 comments)

What makes you think people don't die sitting at desks? As an extreme example the vast majority of those in the twin towers in NYC on 9/11 who died, sat at desks all day and died at work. There are of course numerous other examples ranging from Legionnaires deaths caught from faulty air conditioning to electrical faults and office fires.

Thing is today a chip scale cesium atomic clock with inputs for synchronization to GPS is under 2000USD and the size of a box of matches. So it is perfectly possible.

How Apple Watch Is Really a Regression In Watchmaking

jabuzz Re:How big a fuss is it, really? (415 comments)

A mechanical watch can never be more accurate than a quartz one, excepting you have a really rubbishy quartz one and a really good mechanical one.

Put simply you cannot change the laws of physics.

Car Thieves and Insurers Vote On Keyless Car Security

jabuzz Underground as rare as hens teeth (221 comments)

At least in the U.K. which is where the article is about. Basically underground car parks at private residences don't for practical purposes exist in the U.K., which is why the article *NEVER* mentions them at all.

Never liked the idea of a keyless car, just being near the car means anyone can get in the car as you approach. Heck even if it is parked on the drive and the keys are inside. One of the stupidest ideas in existence really.
