Will the Nissan Leaf Take On the Tesla Model S At Half the Price?

jabuzz Re:Oh noes, I can't drive X miles (332 comments)

No way can two miles be walked in 15 minutes, you would need to run to get that sort of speed.. A fast sustained walking pace is four miles an hour. This requires you to be reasonably fit however. My mother who is now in her 60's is unable to keep up if I walk at that sort of speed.

So you are looking at 15 minutes for a mile. A two mile walk is therefore 30 minutes. I walk two miles every day into work and two miles back. If I really push it then it's 25 minutes, normal is 30 minutes and if I saunter a bit it is 35 minutes.

I work in the west coast of Scotland so it is dam wet. However I have GoreTex shoes that just look like ordinary smart casual shoes, Rohan Dry Requisite Trousers (they look and feel like a regular pair of chino-style trousers) I only wear these if it is forecast to rain heavily, and a selection of fully waterproof and breathable coats for both summer and winter; for example I have a GoreTex smart wool coat for winter. Looks like a smart wool coat, that just happens to be fully waterproof and breathable.

I normally walk full tilt so 25 minutes into work, and four miles of walking a day is good exercise.

Experts Say Hitching a Ride In an Airliner's Wheel Well Is Not a Good Idea

jabuzz Re:What I want to know is ... (218 comments)

I think we can accurately come to the conclusion that the current crop of fundamental Islamist terrorists are remarkably incompetent.

For example take Richard Reid aka the "shoe bomber". Only a completely incompetent idiot tries to light a fuse in full view of everyone, rather than take the simple expediency of locking yourself in the toilet!!!

To underline how stupid and incompetent they are the "underwear bomber" made exactly the same critical mistake.

Pollution In China Could Be Driving Freak Weather In US

jabuzz Re:So stop buying (so much) chinese stuff (157 comments)

Because if they did it would probably be no cheaper than manufacturing them in North America or Europe, and shipping them over. A large part of what makes manufacturing in China cheaper is that you can pollute like crazy. It is also not just smog from air pollution, but pouring toxic waste into rivers etc.

Pollution In China Could Be Driving Freak Weather In US

jabuzz Polution tax (157 comments)

Simple; tax all goods on the amount of pollution used in their manufacture. Set the level so that it does not effect the U.S.A. (Europe and Japan use less energy anyway) and problem solved. Will have a nice side effect of making it less worth while off-shoring manufacturing to China where it is largely cheaper because they don't have to worry about pollution. So not only is it good for the environment it is good for jobs.

Slashdot Asks: How Do You Pay Your Taxes?

jabuzz Re:What about capital gains or dividents? (386 comments)

True but if you have any sort of investment, or get any interest from savings (that is not in a tax free savings account) then in reality you should. That's means most higher rate tax payers should be doing tax returns.

Slashdot Asks: How Do You Pay Your Taxes?

jabuzz Re:What about capital gains or dividents? (386 comments)

Yep all taxed at the lower rate of tax unless you declare that you are not a tax payer. If you are a higher rate tax payer you will be doing a tax return and have to pay the extra.

Hewlett-Packard Admits To International Bribery and Money Laundering Schemes

jabuzz Re:well, it takes two to tango... (139 comments)

Really, Greece less corrupt than Poland!!! You are on the crack pipe mate. The Corruption perceptions index 2012 has Poland scoring 58 and ranked 41 in the world, where as Greece manages just 36 and is ranked 94. Greece has the worst corruption problem in the whole of the E.U. including all the ex communist states. Greece can only dream of having as little corruption as Poland.

How Cochlear Implants Are Being Blamed For Killing Deaf Culture

jabuzz Re:Let it die (510 comments)

The point was he made a really really stupid and dumb decision that ultimately cost his life. If Steve Jobs is able to be so insanely stupid, and refuse proven "cancercure(tm)" then so are other people.

Getting back to "deaf culture", the way I see it is that if parents refuse treatment for their deaf children then society should have the right to withdraw the financial support they would otherwise provide to that child. In short cochlear implants while not cheap are cheaper than supporting a completely deaf person for the rest of their life. Want to remain deaf do it with your *OWN* money.

Seagate Releases 6TB Hard Drive Sans Helium

jabuzz Re:obsolete (147 comments)

No, they are all spinning aluminium or glass that are coated with none iron based magnetic materials. I don't think iron based platters have existed for many many years.

That said your post is amusingly clueless as to real world bulk storage. Unless there is some major breakthrough there is at least another five years before SSD world wide production can match spinning hard disk capacity, and that assumes hard disks stand still. On the other hand expect 15k and 10k disks to disappear over that time frame. Shipments of the faster drivers are already dramatically down as people are replacing them with SSD.

Will Cameras Replace Sideview Mirrors On Cars In 2018?

jabuzz Re:Why stop there? (496 comments)

Because it is safer in a crash. When you come to a grinding halt your body simply gets pushed back into the seat over a large area. Facing forward it all goes through the seatbelt, though airbags have helped. Still it is better to be facing backwards, just wish seats in commercial airliners faced backwards.

Ask Slashdot: Experiences With Free To Air Satellite TV?

jabuzz Re:April First????? (219 comments)

You do know that you can get heaters for satellite dishes that fix the snow issue? Try your favourite internet search engine.

Note the issues with rain suggest that you needed a bigger dish. That might also apply to trees, though you could also try pruning the trees is possible.

Tesla Model S Gets Titanium Underbody Shield, Aluminum Deflector Plates

jabuzz Re:Check out some Volvo ads (314 comments)

Yeah but that is because the USA has all these intersections/cross roads instead of roundabouts, and no enforced seatbelt rules.

In a more sensible country which does have these features, deaths per 100,000 is 2.75 instead of 10.4, and deaths per 100,000 vehicles is 5.1 instead of 15, and deaths per 1 billion km is 3.6 instead of 8.5.

Or maybe it is because we are all such great drivers in the U.K. :-) Though our driving tests are far more rigorous than the ones in the USA.

More Than 1 In 4 Car Crashes Involve Cellphone Use

jabuzz Re:Did the accident rate increase? (367 comments)

Some 20-25% of papers in Science and Nature when analysed by qualified statisticians where found to be just plain wrong.

Here's a clue statistics is hard; really hard and the vast majority of people using then have no idea how hard they are and make basic mistakes all the time that don't get caught.

How Do You Backup 20TB of Data?

jabuzz Re:Hmmm... (983 comments)

I would imagine the cheaper drives on eBay will be the ones with the Fibre Channel interface, because most people will run a mile on seeing that. So I see a 48 slot library with two LTO4 drives going for 2000USD.

The trick to realize is that even dual 4Gbs PCIe FC card can be had for buttons, and the drive an library will work perfectly well in an arbitrated loop, no requirement for a switch and OM2 LC-LC cable is also cheap.

New LTO4 tapes are ~30USD labelled, I reckon on 1:1.25 compression ratio so that is around 50TB of backup capacity, not bad for under 4000USD investment.

The next trick is to realize that in a few years you can swap out the LTO4 drives for LTO6 and keep using the library...

Intel Rolling Out 800Gbps Cables This Year

jabuzz Re:Will we still talk ethernet over it? (101 comments)

Well there is 802.3ad of course so yes. This seems to be more about using silicon diodes and multimode fibre to be cheaper in the short term than using single mode fibre and other laser sources.

Stanford Bioengineer Develops a 50-cent Paper Microscope

jabuzz Re:Resin lenses ? (83 comments)

Not just resin. We have been molding glass aspherical lenses for sometime with high precision and relatively cheaply. You would need a fairly largish aspheric for it to be ground these days, and even then they probably start by molding it first.
