Hadron Collider switches to heavy ions, tinfoilers wet pants again

Albert Gonzalez

Relativity ....

I'm sorry to dissapoint you, but at those speeds velocities, don't add.

Energies do.

From the PoV fo one of the ions, the one in collision course never is faster than c, mainly because it's time is slower than for the inertial observer.

Mine is the one with the Relativity for Dummies in the pocket.

HT TXxxxxx MOBO Repair hint

1 - Cover your mobo (plain board, all extras not soldered demoved, esp. plastics and battery) with tin foil (aluminium, really)

2 - Place your covered board in a convection oven at 150ºC for 2 hours, placed in the middle of the oven, NO GRILL

3 - Le it slowly regain ambient temperature, reomove foil and use as new. Board repaired.

The process has to do with the difussion ressoldering of the cracks in the solder joints produced by crystalization.

Price drop

"Samsung reckons its enterprise SSD prospects are good, quoting Gartner numbers claiming worldwide SSD units and revenues for enterprise application will grow from 324,000 units and U$485m in 2009 to 6.3 million units and U$3.6bn in 2014."

Which means lowering the average price per drive from $1400+ to a more palatable $571

Burn, wallet, burn ...

The last storage array you will buy

Albert Gonzalez

New strorage paradigm ...

I think that the future storage will be of two types :

1 - Direct into PCI storage modules, allowing the speed of nearly direct system bus interface, as a substitute of actual disk drives. After all it is a waste of resources having to serialize your data requests, send them on a wire, to get them decoded to a memory, send the data back, and then copied to antoher memory.

Just interface the flash memory directly. Your processor will see its lower nGb of dram, and then a hige space of nGb of directly addressable flash memory. Get rid of the layers between them.

(Of course the devil is in the details)

2 - Add ons, of lower speed and/or bigger capacity and/or lower cost, as external modules, plugged in a bus a la usb or sd cards, and removable.

Lead walls

Excuse me, but lead walls can be very easily cutted down with a plumber's torch. 19'99€ at yout local hardware or DIY store.

No need to open the door.

Alternatively, 3 consecutive steel reinforced concrete walls, with some steel and sand sandwitches between them are harder to break.

Plane modelling


You can use the X-Plane simulator to build and test a model of the plane, also with the simulation on how will fly from release 'till touchdown.

Is not a difficult program to use, and I'm sure that the owner (Austin) would be very happy to provide you with one copy, because of the publicity involved.

Is one of the few plane simulators that can be FAA certified, and I myself can assure you that the model of a CESSNA 1732 behaves exactly as the live one.

CE Tagging

The CE tag is _self issued_, meanig that you as a manufacturer had done all the ccontrols and measurements to assure it.

If you've not done it, you're obliously lying, and emmiting a false certificate, so you can be prosecuted.

Here in Catalunya (Spain), the ploice checks from time to time the documentation of the wares sold, and there is a very simple mechanism for the user to complain. Once there is a complaint a full review and/or test must be made. If the manufacturar/importer is found guilty, all the affected wares are retired from the market and a fine imposed.

Has been done with toys, electronic devices, foods, etc.

2 cents on CE procedures.

Easy way to protect the phone

Just pop up a message asking the owner for permission BEFORE the software can be installed or uninstalled.

That way, the OWNER can decide if it is a transfer he asked for, or not, and act accordingly.

Just provide the adequate amount of information on the dialog box, please, and the options:

yes/not now:remind me later/never

Weigth of the tether

To reduce the weigth of the tether, which is mostly the conductor metal, the only thing needed to do is reduce the conductor diameter.

To cope with the increased wire resistance, there are 2 alternatives ( non excluding)

1 - Use a better conductor ( gold ) or a superconductor (just find one that works at room temperatures)

2 - Increase the line voltage, as to reduce the intesnsity to carry the same power. Of course the isolation will have to be enhaced, but plasitc is a lot less dense, even more if is filled with vacuum bubbles.

Huge Fancoil

Just add a huge fancoil to the reactor, and you can start cooling it immediatly.

Use the main turbine's shaft to drive the fan and you will have an inherent negative coeficient system, because the hotter the reactor will get, the quicker the fancoil will remove the heat.

Just assure yourself thar the heat is sent upwards directly, to avoid recirculation problems.

Note to Captain Kirk: Warp speed will kill you

Albert Gonzalez

Warp speed

I'd like to resalt the fact that warp speed, as seen in Star Trek films, exceeds c, so there have to be different physics involved, thank you.

Primary, the branch that studies fictional physics.

Of course, that don't invalidates the professor's study, that is applicable to our very real world, and if I one day happen to be flying in a spaceship fast enough to nottice its effects, i'll fondly remeber him.

On the other way, there are far more bigger problems to get to such speed, as the acceleration needed would be far greater than the one my body would resist, for example, or the amount of energy involved to accelerate the ship.

One beer to a time well spent in an important problem, as I'm doing now.

Toshiba looks ahead, sees a 14TB disk

Raid5, 6 or raidz5

If you need to use > 14TB of space for your data, you best be sure to have it really protected.

Not just a 'simultaneous 2 disk failure' proofed, 'but fire in the computer room' proofed.

So yes, a raid 6 + daily remote sync, and a big pipe.

That is, offsite.

Electricity voltage levels

As an approved Electrician i'm allowed to say you:

Very low Voltage : up to 24V

Low Voltage : up to 500V

Medium Voltage : up to 25kV

High voltage : up to 500kV

Very high voltage : More

Liquid coolant

Water ?

Why not use R410A or other non conductive, non toxic, non corrossive industrial refrigerant and rid themselves of the pipes. Just pump the coolant in one side of the stack, let it flow while evaporating and collect the resultant hot gas on the other side. No pipes, just small expanding holes etched in the surface of the bottom chip, one quick connect pipe socket in each side of the module, and you're ready to go.

Use one compressor for all paralel chips, and get the efficiencies in moving heat associated with het pump aircon systems.

iPhone upgrades - a one-way control-freak street

Albert Gonzalez

Going the Apple way

I was mulling the possibility of moving our small office to apple hardware, because of the 'Just Works' moniker, and the (at least on paper), perceived good value of the iMac i7 machines.

Of clourse, that would pave the way to purchase Apple software, and use iPhones

Then, as the decision times are looming ... the tide of reports of faulty hardware ( DOA iMacs ), bad customer experience, and closed environement for the sotware is making me reconsider the whole thing.

Probably we'll continue as we are now, purchasing build to order PCs from our friendly local store, with Debian, and perhaps, money permiting, some of those 30in HP displays, which, after all, is the MOST important part of any interactive computer (servers and embedded do not need no stinkin' displays)

Pitty, i was willing to play with a Snow Leopard .... and face it against a penguin ... but seems the Leopard has defaulted.

Collisions at LHC! Tevatron record to be broken soon?

Albert Gonzalez

Re: 450 vs 900 GeVs

Dear Dan 10

Gev is a measure of energy. So when you make a colision with two beams in oposite directions the energy adds, irrespective of the velocity.

Of course, the relative velocities will allways be less than c, for every of the 3 points of observation ( 2 beams + stationary observator)

If you want to take into consideration velocities, instead of energies, then the relative times MUST be contemplated, as the time will be slower for the beams than for the ground.

And THIS is the best part of a very high velocity (energy) collision, the time in the collision will be slowed, so boffins can actually measure something.

Hope I explained myself.

NASA plans robot rocket aeroplane to fly above Mars

Nuclear air turbines

You 'just' need to use the nuclear fuel to heat the air inside the combustion chamber of the turbine.

Also, it can use the turbine to move a small electric generator, wich can be used to start the rotation of the engine, if the initial airspeed isn't up to it.

Really easy to test, just 1 moving part, very very long endurance ( as long as the fuel is hot enough )

~ £20K for a PPL ?

In Spain a PPL license costs about € 8K

Including classes, taxes and plane rental.

I know because I asked last month, after having a couple of practical lessons in a cessna 172.

If the cost is ~ £20K in the UK, you will save money coming to Barcelona for 'holidays' , and returning with an european PPL

(The US PPL license isn't fully recognized in Spain by AENA, because in the US is way more cheap )

Regenerative Braking

The huge energy saving from an electric car comes from regenerative braking.

In an open road, where you almost don't have to brake, there isn't nay gain, but while driving in a city, you will get a big gain when braking for all those semaphore lights.

In an ICE, the kinetic energy will be just dissipated as heat.

In an ICE, the engine will consume power while at the red light.

Also there is a far better way to storing power : flywheel. Just isn't as cool and adaptable as batteries. You have to design the car around the flywheel, and not the other way. There are other difficulties with a flywheel, but are all solvable with the current technology and some cunning.

The only problem is that you need a 1'8m wide, 500kg flywheel at 15.000 rpm to store a fuel tank of energy. I made the numbers.

Apple yanks C64 emulator from App Store

Albert Gonzalez

Poke, Poke, Poke

Yup, you can write an app loader in basic that will be able to load apps and execute them, in binary form.... that will access the filesystem, and possibly other phone resources.

Also, there MAY be a way to use a buffer overflow inside the emulator to execute some code natively in the iPhone, so a malicious program may:

1 - Load a payload inside the emulator and break it to execute the payload as an iPhone program, and NO as a C64 program

2 - Once the payload is executing as an iPhone app, it may do a lot fo nasty things, only limited by the ability of the iPhone Security ( ehem ... )

So yes, may seem an overkill, but the emulator MAY be a vector to the phone.

2 - Modulator for powerful EM beams ( such as used in communications )

3 - Shutter/dimmer for spectacular lights, just found a way to stop that 5kw without powering down the bulb. At last will be able to use cheap arc bulbs.

4 - Sun shades for the windows (if made big enough).

DIY hipobaric chamber

Get a piece of concrete pipe big enough for your needs, put a thick ( > 30mm) metacrilate circle on both ends, one end attached with some flexible cement (poliuretane may be a good choice, the other end justa a rubber ring.

On the fixed plate, insert a fitting, and ask your local air conditioning guy to lend the vacuum pump to evacuate the air.

Envelope the concrete with plastic film to seal it.

When ready to go, insert model into chamber, engage the pump, hold the rubber ring end until pressure starts to drop and observe the effects from a safe distance.

If the chamber can be smaller, a bottle with a big mouth may be easier.

You can also evacuate air with pirotechnically assisted methods, bur are trickier.

And for the electronics, i reaffirm myself that a HTC Dream / Hero is the way to go, beacuse it has it all included and tested, so you ONLY need to write the software (he he he).

Re:How to slow your computer down to a crawl

Hi Michael

Yes, I use KDE in a production environement, and because of the age of my machine (4 yrs old), i had to disable all desktop effects when i upgraded from KDE 3.5.9 to KDE 4.2.

Once they are disabled, the system works very well, but not as snappy as with xfce.

Is your choice, but the glint don't add to productivity, and the speed improvement is very big.

Of course, you can always use another wm.


El Reg to launch space paper plane

Albert Gonzalez

Technical data:

Energy :

To get energy to the electronics in the plane, you can use a pair of small propeller blades attached to a pair of dinamos, that will recharge a small battery, so you will use the dinamos as a way to reduce the amount of kinetic energy, and power the electronics and, possibly, actuators.

Excess energy to heat the electronics enclosure.

Computer control:

As a computer control, you can use an HTC Dream, with android, that has accelerometer, magnetic field sensor, wifi, gps, compass, video camera, is fully hackable, and you have the source code. Should be relatively easy to hack a usb device to control the surfaces of the plane, using PWM and electromagnets. Log all data to the 8Gb microSD card, that propably will survive a fatal crash, flushing the filesystem every 1s. The program for controlling the surfaces don't need to be too sophisticated, as will be using closed loop sevos with the set points controlled by the GPS. The accelerometer can be used as the D paramenter in a PID algorithm.

Stability of the system can be easy to verify with a couple of equations, if needed, but much more fun to launch the plane from the roof.

Altitude sensor:

In addition to the GPS and accelerometer on the phone, you can use a small balloon, that will activate a switch when the outside air pressure drops enough.

Separation device:

Use an electromagnet inside the plane, attached to a piece of iron hanging from the balloon, that will be unpowered on command from the phone and will use the mechanical altitude sensor as a failsafe (serial installation). D Cell battery powered.

Recommended design flow:

1 - Specify hardware needed for the system.

( Just draw a diagram with names. )

2 - Calculate hardware weigth.

( Group all the parts, and put them into a kitchen scale. )

3 - Calculate wing span for plane + 2 x hardware weigth.

4 - Model airplane in X-Plane simulator, while the computer hack is preparing the programs, and the HW hack is preparing the rest of the hardware.

5 - Evaluate total payload weigth, and size balloon acordingly.

6 - Build aircraft.

7 - Test fly it.

8 - Remove possible problems.

9 - Get BAA permissions.

10 - Send the plane.

My 2 cents.

Wikipedia's Gallery guy hung up to dry?

Albert Gonzalez

Image monopoly

I'm a usual cultural traveler, i've found myself in the follwing situations:

In Scotland, there are public galleries (SNG), where you can look at the pictures, but NOT photograph them. You can ONLY purchase reproductions in the shop, if they're there.

In France (Louvre), you can make all photographs you want, and ALSO purchase the reproductions.

So the question is :

Can I make photographs of the picture ?

If the answer is yes, then nobody can complain because of copyrighted photographs.

If the answer is NO, then should be a way to obtain reproductions ( for a nominal fee) or a way to download them for FREE in digital format.

My 2 very irritated cents.
