NASA Tests Feasibility of 3D Printing on the Moon and Other Planets

jabuzz Re:WTF (58 comments)

This is an English language website. The term in-situ is something that I would expect at least an educated person from an English language country to understand perfectly. There is a large amount of the English language a none native speaker might not understand, that is no reason not to use it on an English language website. If there is something you don't understand Google if heavens sake.

I am quite sure if I demanded that the French used simple French on their websites so I could understand it they would go positively apoplectic.

Backblaze's 6 TB Hard Drive Face-Off

jabuzz Re:Man, am I old ... (172 comments)

Sure I probably won't look at over 90% of my data ever again. If you can tell me now today which 10% I will look at again you can have everything I own.

As hoarding data is both cheap financially and physically, aka the downside is very small it makes sense.

SpaceX To Attempt Falcon 9 Landing On Autonomous Spaceport Drone Ship

jabuzz Re:Someone doesn't understand basic relativity (81 comments)

Yes the tower backs away and the holding clamps release. However this happens literally as the rocket blasts away. Have you never watched a a video of a Saturn V launch? Try this one a high speed 500fps 16mm footage from the base of the Apollo 11 rocket. Notice how the holding clamps release to let the rocket move away, which they only do when they get the signal from the onboard systems that all five F1 engines are working properly.

Displaced IT Workers Being Silenced

jabuzz Re:More than one reason the coverage is biased (398 comments)

I think the point was at 350 million a mile you could construct 10m high re-enforced concrete wall that bristles with high voltage razor wire, and masses of video sensors. If you include some sort of walkway/track along the top or road behind it and have forts every so often you could physically secure the border and it would not cost anywhere near 350million dollars a mile. Further most of the cost is a one off; maintenance and garrisoning would be a lot less than construction.

If the Romans could manage in six years to construct a a 76 mile long stone wall with forts every mile (actually less because they where Roman miles) then the USA can manage it with the Mexican border.

A combination of Google and Wikipedia tells me the Israel Egypt barrier cost 1.6million USD per mile (though this is most barbed wire) it cut illegal entry through the Sinai into Israel by a factor of 280 before it was even completed. The West Bank barrier that is mostly 5m high concrete costs 3.2million USD per mile so lets be generious and say 4million per mile so 2000 miles is say 8 billion. Heck even the UK is going to spend half that on the F35. One Gerald Ford class aircraft carrier is 13 billion USD.

Answer is that a strong barrier between the USA and Mexico is perfectly possible and the cost is entirely reasonable.

China Plans Superheavy Rocket, Ups Reliability

jabuzz Re:That happened back in the 1970's (86 comments)

Please stop equating the west with the USA. The maths that Americans do is way behind their European counterparts as well.

Part of it is much shorter school years in the USA. Typically 20 less each year. By the time you get to 16 that is over a year less education than their European counterparts.

Programmer Father Asks: What Gets Little Girls Interested In Science?

jabuzz Re:Yeesh (584 comments)

I think you missed the bit where I was talking about my nieces and nephew. Yes they where both interested in cars, but my nephew was totally intrigued as to how they worked. Sure *some* girls will show the same interest in how they work as well, and some boys will also be completely disinterested. However on average boys are far more likely to take things apart to find out how they work than girls. It is therefore unsurprising that this manifests itself later in life with more males in STEM than females.

Is there cultural bias to toy selection in children, sure. Is it all down to cultural bias, hell no; the experiments with apes are pretty conclusive on that subject.

Programmer Father Asks: What Gets Little Girls Interested In Science?

jabuzz Re:Yeesh (584 comments)

They way boys and girls play with cards and trains is different. My two nieces both played with the same toy car at their grandmas. But only my nephew picked it up turned it over and was fingering the wheels to see how they went around. This is the same car from the same box of toys so they all had the same options.

There was a BBC Horizon on is your brain male and female where they left toys in an ape enclosure at a safari park in the UK. I nearly fell of my seat when the male apes picked up the cars turned them over and where fingering the wheels in *EXACTLY* the same why my 9 month old nephew had done, but neither of my nieces had ever show any inclination to do when playing with the very same car. For reference the female apes in the program exclusively picked up "girl" toys.

There have been a number of experiments with apes of different species now and all have show dramatic gender preferences towards toys. True in some species/experiments (all the experiments seem to use different species of apes) the preference is restricted to the males, but in some species/experiments it is present in both females and males. Clearly the idea that toy selection in children is all down to social pressure is complete and total nonsense.

It will be interesting to see how my third niece who has an elder brother totally mad for trains behaves. So far she has spent 15 minutes watching a train go around a track aged five months. She was even pushing on her legs to get a better view as the train approached the side of the settee, and head following the train around and around. Big brother meanwhile was laid under the table on the floor also watching the train go around and under the table also totally mesmerized. The two elder nieces never got access to this toy because we thought it had been given away years ago till I found it in my mothers loft a month ago.

UK Announces 'Google Tax'

jabuzz Re:Why tax profits, why not income? (602 comments)

Show me anyone outside the 1% and even 99% of the 1%'ers that would choose to make less money because they where being taxed too heavily on it. That is a complete fallacy.

UK Authorities Launching Massive Child Abuse Database

jabuzz Re:Nice attempt to look like they care (150 comments)

The number seven comes from what the Crown Prosecution Service have chosen to prosecute and got convictions for. They have many more on file. Some will be where the victim is unwilling to give evidence in court, or the CPS believe would not make a good witness on the stand. The job of the CPS is to make sure the bastards rot in jail, this does not necessarily correspond to prosecuting all possible cases of abuse.

It is quite clear that the abuse was wide spread in Rotherham and worse was not confined to Rotherham either. There have also been very similar cases in Derby, Oxford, Bristol and Telford. All involving gangs of majority Muslim background perpetrators sexually abusing and trafficking mainly white girls.

Chromebooks Overtake iPads In US Education Market

jabuzz Re:Adminstration (193 comments)

Add in that a $499 Mac mini is not a server. It has no redundant PSU, has no hot swappable redundant hard disks and is not rack mountable at least not without third party hacks.

The moment Apple stopped selling the Xserver's running any OSX server stopped being an enterprise solution.

Chromebooks Overtake iPads In US Education Market

jabuzz Re:Disgraceful considering Google's age restrictio (193 comments)

I would imagine the bit he is unhappy about is that as a parent he is unable to go and buy his child a Chromebook for a laptop because it requires a Google account and unless he lies about the child's age he cannot create a Google account for said child. Yet Google are pushing Chromebooks as a great laptop for kids which I believe it is. However you can only use one if it comes through the school. Which if your school does not provide laptops for your child or provides an iPad which is useless for typing an essay you are forced to lie.

As a parent you should be able to create a Google account for a child that is a subsidiary of and/or linked to the parents account. Simple really.

Sony Pictures Computer Sytems Shut Down After Ransomware Hack

jabuzz Re:Dear Sony, I am delighted! (155 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 (143 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? (247 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? (642 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.

jabuzz Re:What about the male stereotypes? (642 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.
