Here – here is that 'hoverboard' you've wanted so much. Look at it. Look. at. it.

Moore's law for batteries

A few years ago, batteries got about 20% extra capacity per year while the price dropped 20%. These days, the capacity figure is closer to 5% per year. The price reduction is harder to estimate because battery prices are now mixed in with fire bomb prices.

Physics limits battery energy density to about three or four times what you can buy today. Electric motors are about 80 to 90 % efficient, so room temperature super conductors, magnetic bearings and all possible advances in tech only get you another 25% at best. The complete board is 10kg. If we split that 50/50 for batteries and motors, and use magic massless motors, we can double battery weight and get to a theoretical limit of almost an hour in the air.

The big problem with the hover board design is it moves a small area of air very fast. You can get the same thrust for less power if you move a large area of air slower. At a guess, the model jet engines mentioned above use low temperatures to simplify the design, reduce maintenance and use cheap materials. Engines on big aircraft push cold air through the inside of the turbine blades made from high temperature materials so they do not melt. This allows a higher combustion temperature, which improves efficiency, so better power to weight ratio and less fuel used.

If you design a small turbine with similar features to a big aircraft engine and use it to spin a big propeller, you get a helicopter hover board that can fly for hours with existing tech. (Also requires a pilot's licence, regular maintenance and a really big bank balance).

Re: Comparison 36x electric fans with 8x mini jet engines

The specs we have for the electric product are 10kg board, 80kg passenger and 200kgf of thrust. I will assume that the average thrust is 90kgf, but that it is distributed unevenly among the fans to keep the board from flipping over.

The jet proposal has 8x 52lbf of thrust for a maximum of 189.1 kgf. If we assume the same 90/200 ratio to keep control, the mass of board + passenger must be reduced to 85.1kg. The jet engines require 25oz/minute of fuel each at full power. Scaling that by 90/200 because the engines are not set to full power all the time, six minutes of hovering time uses 16.34kg of fuel. Lets call that 8.17kg because the fuel tank starts full and ends empty. The engines are 2.51kg each. If we allow 0.34kg to provide a surface to stand on, and hold the engines and fuel tank together then we are down to 57kg for the passenger.

To match the electric product's 80kg passenger, we need 12 jet engines weighing 30.1kg and costing $51,540. Also 23kg (7.5 US gallons) of jet A1 1-K aviation fuel per 6 minutes of hovering. As well as burning a hole in your wallet, the jet's exhaust is 750°C, so it will burn your house down if you ride it indoors.

Re: Disk glue

Every time I have dismantled a disk, it has been held together with screws (I have not tried one full of helium yet). There are plenty of processes making and populating PCBs that could leave a smell, but none of them are unique to a hard disk controller card. My first hard disk (320MB was big in those days - full height 5¼") had a packed PCB that was the full size of the device. These days, the disk is a quarter the area, and the PCB is even smaller.

Secure Boot

Secure boot throws away any hope of security. Old style BIOS is sufficiently small and stupid that it cannot do much more than read and execute a boot sector. Secure boot is huge. The chances are that the copy you have is based source code released by Intel, with whatever additions the manufacturer's government insisted on plus two huge binary blobs from Intel big enough to hide something that can man-in-the-middle an ethernet port and provide remote exfiltration invisible from inside the computer.

Bit locker keys can be read by an external device via a 1394 or thunderbolt DMA channel. If all else fails, reset the machine and boot from an external device. The keys can often be found in memory left over from the previous boot.

Securing a computer against physical access by a rich and determined attacker is really difficult. Grub's password feature is only a significant barrier if you have covered all the other bases.

Almost possible to use grub password

Some cases have intrusion detection switches. I can wire that to the erase CMOS nvram pin. Now I can close the case, configure the BIOS to boot, but only allow changes to the boot order with a password. Next up, enable grub's password feature so the boot options can only be changed with a password. Now encrypt the server's secret key and store the password for it in CMOS nvram.

The server's certificate is now more difficult to get at if the attacker has physical access. There are two more things you need to sort out: all USB ports should be disconnected (and wired to the mains). Also, add an X-ray detector and use it to trigger some thermite. (The police will first attempt access with a USB device, then take an X-ray to cut into the box without triggering the intrusion detection switch).

Now to actually use that grub password, you need a USB to PS2 converter inside the box, and use a bulkhead mounting PS2 connector to get the signals out.

The whole idea of an embedded system is that it works without the assistance of a user. If grub is set to require a password on boot then after every power cut, some poor techie is going to have to trudge out to darkest nowhere, dismantle the box and solder in a keyboard before typing a password.

Re: small issue of air density

The fun thing with Dyson patents is to look at some history. A century or so ago, vortex separation was used in coal mines. Over three decades ago vortex separation was used in bus exhausts to reduce particulate emissions. There was a vortex separator at a sawmill where I worked long before Dyson invented the vacuum cleaner. Like everyone else involved in technology, I do not look at patents because they are obfuscated, obvious, describe antiquated tech badly and looking at a patent means triple damages for wilful infringement (and expensive nuisance litigation if you do something similar but non-infringing). So without looking at Dyson's patents:

Flywheel energy storage has been around for decades. The big advantage is the rapid discharge time, so to obvious uses are things like throwing aircraft off a carrier or powering a data centre for the few seconds between a power cut and the generators starting. There was a big step up in capacity per kilogram when people switched to composite materials. In 2004, NASA built one that could store 16kJ/kg. For comparison, super capacitors store 36kJ/kg, Lithium ion battery: 1800kJ/kg. Ham and cheese sandwich: 10130kJ/kg. The popular energy storage for a Mars rocket is Methane+Liquid oxygen which you can make from Mars's atmosphere if you bring a nuclear reactor and your own hydrogen. The resulting energy density compares well to a ham and cheese sandwich, so over 600 times better than a flywheel storage device built with an astronomical budget; eg: launch costs per kilo swamp the costs of expensive materials and expensive manufacturing processes.

If you are going to try flywheel storage for a Mars landing, the time to charge up your propeller is after you have slowed down enough that the propeller will not get vaporised by friction with the atmosphere, but while you still have enough speed and altitude for autorotation.

If Dyson were involved in space travel, I expect he would patent what other people are doing now and sue them when they start to make a profit.

Re: Police level trained

There is a wide range of police training. This is not the link I was looking for. The one I wanted was much clearer. For example, the link I could find says thirteen officers get shot but does not say if that includes the 8 that shot themselves, or how many of those 8 were accidental shootings. At first sight, it looks like the police shot more suspects than bystanders but the link I wanted split the 24 dog shootings into suspects and bystanders. I do remember that according to the statistics the safest thing for the bystanders to do was to reach for a concealed weapon and look threatening - if the police aimed for you, they were more likely to hit someone else. The safest thing for the actual suspect to do was to stand next to a dog. Innocent dogs caught more gunfire than suspects.

Many police forces train their officers until they pass a test, then practice stops for lack of time and money. As a result, gun nuts who practice regularly are often better shots than an average policeman. I am all in favour proficiency tests for people who want to own dangerous tools. 'Police level training' is not a clear standard, and in some states it is dangerously poor.

Re: Is source code necessary to validate correctness?

Test cases sufficient? Ask VW.

Personally, I think this software has no value in elections until the source code is available for review. This also makes to possibility of secret illegal copying impossible: whoever copies it is going to have to provide the 'their' source code for verification, leading to immediate proof of illegal copying.

Microsoft makes Raspberry Pi its preferred IoT dev board

Flocke Kroes
Silver badge

There was a reason these were given away free

Plan A: Arduino compatibility. Galileo could run Arduino software via in emulation. There result was hundreds of times slower than a cheaper, lower power Arduino board. There is simply no point in a big expensive CPU for applications that already work fine on an Arduino.

Plan B: Raspberry Pi competitor. Although Galileo's CPU is half the clock rate of a Pi, it does more instructions per clock, and works out about the same speed as a Pi B1 CPU. At twice the price, and quadruple to power, the only advantages Galileo had were one lane of PCIe and the ethernet port did not take bandwidth from the USB port. There are other ARMs in Galileo's price bracket with those features, and a Pi B2 has four faster CPU cores and the same GPU as a B1.

To enter the IoT market, Intel has to release a product at near cost that reduces sales of their higher margin products. So far, Intel has decided that a proper IoT product does them more harm than good.

Microsoft knows this move is a kick in the teeth for both of the developers using Windows on Galileo, but anybody using Windows for anything must know by now that one day it will be their turn. It could not have been a surprise.

'Easy' ways to get and validate keys

You can get keys with the magic command 'gpg --keyserver wwwkeys.uk.pgp.net --recv-keys KEY_ID'. Unfortunately, to work this out for yourself, you have to read the manual. You can get mutt to retrieve the correct key for a particular encrypted email by adding the following to '~/.muttrc':

set pgp_getkeys_command="/usr/bin/gpg --no-verbose --batch --quiet --recv-keys %r"

and by adding something like 'keyserver wwwkeys.uk.pgp.net' to '~/.gnupg/gpg.conf'.

There are similar settings for encrypting, decrypting, signing and verifying, each at the press of a button (plus typing in a proper password for decrypting and signing). Other mail user agents may or may not be as easy to configure :-)

The obvious way to get the right key is to meet in person and exchange keys - or at least key finger prints. The less obvious way is to read and understand how the chain of trust works.

Communicating private messages requires reading and thinking, so it is way too much effort for the average netizen. Dumbing it down just means people will think a picture of a key on a web page means it is safe to type in their bank details.

God's net worth

I did not expect to find a single clear undisputed value because the catholic church has many large properties which are difficult to put a price on and plenty of people would like a large or small number to support their propaganda. I did see plenty attempts at passing off misleading numbers (both sides), and some (over simplified) ways to value unique property were not even mentioned, eg:

(Tourist revenue - maintenance)/(Competitive return on investment)

After a quick search, I can clearly state that over a decade ago the catholic church either had for more or far less value than the current market capitalisation of Google, depending on where you look and what currency they were using.

Has anyone seen convincing, clear and honest official numbers? I bet Tim Worstall could do an article that leads to a spectacular flame war.

Any time he pushes users to cloud first equal, he pisses of the desktop users. The obvious way to make money is to bump up the prices for locked in legacy users, and what a surprise, people scream when he does that too.

Somehow he has to balance between legacy support and securing a future. Any decision he makes will be interpreted as a recipe for catastrophe by half is divisional managers, business partners and customers. The monopoly is broken, so profits will fall whatever he does. Both sides will point at that and say it was his fault for not being 100% traditional and 100% modern.

Re: Apple thieves - what a surprise

Creating verilog code is expensive. Proving that some verilog does what you intended is really expensive. I agree that Apple should pay for all the verilog code they stole from the patent. A quick look at the patent shows zero lines of verilog and zero evidence the the verilog does what the patent describes.

There is some theory that one among the thousands of people who independently came up with the idea should be able get a monopoly on its implementation. If something is so obvious that no-one writes it in a technical journal, it is proof (to a patent lawyer) that the idea is unique and valuable. This dates back to the Dewar bottle.

A Dewar bottle is a delicate piece of lab equipment that can hold hot or cold liquids and keep their temperature roughly constant. A judge upheld the patent on a thermos flask (a Dewar flask robust enough to survive getting dropped) because the idea of making a Dewar flask robust would not have occurred to anyone but the patent holder. The judge pointed at a picture of a Dewar flask to show how different it was from a thermos. In the background of the picture you can see the thermos made by the lab-tech who took it on pic-nics to the delight and amazement of his family. The lab-tech, James Dewar and hundreds of other lab-tech and physicists knew that the thermos was to obvious to patent. The key quality that is required is the willful ignorance of a patent lawyer.

On another day, I would happily slag Apple for suing others who build things that Apple copied, but not for this.

Re: Unsurprising. This is *monitors* after all

Monitor specs from all manufacturers have been dishonest for decades. CRT monitors were credited with a higher resolution than the number phosphor dots. Repeating the contrast ratio measurements required a lightless cave painted dark black. High scan rates were possible, but the pixels became blurred because of lack of bandwidth. These days its 4K resolution - with a 15Hz frame rate (interleaved).

As soon as a particular specification influences purchasing decisions, every manufacturer hunts for ways to make the number better - whether or not it reduces the quality of the product. The solution was to go to PC World to select a monitor, then buy it somewhere that did not charge £30 for the cable.

Wait a couple of weeks, and you will see what naughty things the other manufactures have done to get their high scores.

Apple bought their displays from Samsung. There was no-one else capable of making them. I assume there followed a discussion between Apple and Samsung about the price of phone LCDs.

Apple invested in a glass manufacturer (GT Advanced Technologies) to upgrade their equipment and sell sapphire glass to Apple at a loss. The project was so successful that GT filed for bankruptcy (a popular activity among Apple's suppliers).

For all we know, Samsung have already got their money back by charging Apple extra for components. Despite all this, there are still winners an losers here. Apple's shareholders have paid some hefty legal bills.

Re: if they used GPL code in their products...

The magic word is 'linked' not 'used'. This is clearest for compiled languages. Compile various C source files to object files and link them. If any of the source files is GPL, then all of them must be GPL (or multiple licenses including GPL) in order for the reseult to be distributable. The same goes for linking (dynamic or static) to a GPL library.

There are ways to use GPL and closed source software together. Ubuntu is an aggregation of GPL and code with other licenses. Simply distributing two programs on the same DVD does not prevent GPL and closed source from being sold at the same time. Communication via file descriptors is not linking. Although kernel modules and dynamic linking have much in common, closed source kernel modules are explicitly permitted (but sufficient reason for many penguins to buy something else rather than hardware that requires a closed source kernel module for its driver).
