Submission + - Serial port command hack for Rigol Oscilloscope (

altzone writes: Clever EEVblog viewers have figured out how to send a few simple serial port commands to turn the cheap Rigol DS1052E 50MHz oscilloscope into the more expensive 100MHz DS1102E model.
It turns out Rigol left the barn door wide open and didn't adequately protect their "crippled" low cost 50MHz model, which actually has identical hardware to more expensive 100MHz model.
Change the model number and serial number via the serial port, and Rigol's firmware switches the hardware filter bit and 100MHz bandwidth is all yours!

No. "Meta" is the most overused bullshit term ever.

It simply means "about".

Any "mata" data has to be external.
You can't have an object with internal meta data (about itself) because that data's existence (regardless of it's content) alters the object, and is part of it.

Even if it were self-referential, it's not meta.
And even if you want to use the word meta to describe it, the shape of a physical object is certainly not meta data. If we're referring to an object as data, then the entirety of the object's physical state must be described as such.


Submission + - Carmack speaks on ray tracing, future id engines (

Vigile writes: As a matter of principle, when legendary game programmer John Carmack speaks, the entire industry listens. In a recent interview he comments on a multitude of topics starting with information about Intel, their ray tracing research and upcoming Larrabee GPU. Carmack seems to think that Intel's direction using traditional ray tracing methods is not going to work and instead theorizes that using ray casting to traverse a new data structure he is developing is the best course of action. The "sparse voxel octree" that Carmack discusses would allow for "unique geometry down to the equivalent of the texel across everything." He goes on to discuss other topics like the hardware necessary to efficiently process his new data structure, translation to consoles, multi-GPU PC gaming and even the world of hardware physics.

Submission + - Nintendo Wii Fully Hacked at 24C3, runs Homebrew (

cHALiTO writes: "From the site:
The guys over at 24C3 just demoed a Wii hack that is set to provide native Wii homebrew in the near future (not running in GC mode, and with full access to all the Wii hardware!)
They were able to find encryption and decryption keys by doing full memory dumps at runtime over a custom serial interface. Using these keys, they were able to create a Wii 'game' that ran their own code (their demo happened to show live sensor/Wiimote information, amongst a few other things).
Read here and watch video here."


Submission + - IEEE Spectrum's Holiday Gift Guide

perbert writes: With the holiday consumer season approaching rapidly, here are some of the more technologically inspired presents you may want to put on your wish list for the jolly old elf. Consider: your own personal submarine (for a mere US $130 000); or a robotic lawnmower that works while you rest. (Oh, and there's also an article about Slashdot in this issue.)

Submission + - Cisco offers $10m network innovation prize

Stony Stevenson writes: Cisco Systems has announced the launch of the Cisco I-Prize which offers up to $10m to global entrepreneurs with commercially viable network technology business ideas. The winning team could have the opportunity to join Cisco as founders of a new emerging technology business unit. Depending on the value of the idea, Cisco may also invest a further $10m over three years to fund the new business unit.

The prize is open to individuals aged 18 and older and entries will be evaluated in much the same way that Cisco assesses new internal business ideas for its Emerging Technologies Group. The only catch is that ideas must have the potential to bring in at least $1 billion revenue to Cisco over a five to seven year period, and submissions must use the IP network as a platform.

Submission + - Investigating ' secure' USB sticks

An anonymous reader writes: Dutch company Fox-IT investigated a number of 'secure' USB sticks. During the investigation, several techniques were used to see whether information could be retrieved from the sticks. The report has now been released to the public.

Submission + - European physicists take photo of neutrino

An anonymous reader writes: European physicists said Tuesday they had sent an elusive particle known as a neutrino on a 730-kilometer (456-mile) trip under the Earth's crust and taken a snapshot of the instant it slammed into lab detectors. In the October 2 event, a neutrino hit one of the 60,000 bricks that had been installed in San Grasso, leaving a tell-tale track of a muon on the film. The experiment is important, say the investigators, as it could help explain one of the biggest mysteries about the Universe — its missing mass. When scientists tot up the mass of all the visible matter in the Universe, they arrive at a total of just 10 percent of what they know to exist. For years, neutrinos were not thought to have any mass, although that theory has been challenged by experiments at Japan's SuperKamioKande lab, which suggested that they may have a mass, albeit a very tiny one.

Submission + - Intel tests 80 Core chip

Zeinfeld writes: Intel has announced a test chip with 80 cores. The chip has a nominal processing capacity of over a teraflop. Whether the chip actually delivers that performance over a sustained interval on real processing problems is another question. Also unmentioned is how the issue of heat dissipation is dealt with. It is probably going to be a while before such chips are production.

This marks a major departure from tactics such as introducing more parallelism into the processor core and adding more cache memory that have been the norm since 64 mainstream processors reached 64 bits.
