“How many people have ever lived?” The numbers in this piece are highly
speculative but are as accurate as modern science allows. It’s widely
accepted that prior to 2002 there had been somewhere between 106 and
140 billion homo sapiens born to the world. The graphic below uses the
conservative number (106 bn) as the basis for a concentric circle
graph. The red dot in the center is scaled to represent how many people
are currently living (red) versus the dead (white). The vertical line
represents time. The spectral graph above the circle shows the
population ‘benchmarks’ that were used to estimate the population over
time. Adding up the population numbers gets you to 106 billion. The two
spheres are then used to compare against other numbers.
Two security researchers on Wednesday will
demonstrate methods for intercepting and decoding calls and data
transmitted over the popular GSM mobile network technology.
Security researchers Karsten Nohl and Chris Paget presented their findings in a presentation (WMV video) Monday at the 26th Chaos Communication Congress
(CCC) in Berlin. A practical demonstration of the vulnerabilities and
potential exploits is scheduled to take place at the conference on
Wednesday at 12:00 GMT.
Cool ! Connect object to the virtual work in a fashion way.
PS.It can used to replace DRM. Say the M-Company's E-Learning Product. User will received Tags on the Book so every time he/she want to watch the digital contents he/she just wave the tag and application will login and go to the content directly.
The USB Hourglass combines a sand timer with a rotating mechanism and
an optical beam through the center of the timer to observe the falling
sand. The amount of light reaching a detector is digitized at frequent
intervals and processed by a microcontroller to determine when to rotate the hourglass. The digitized light levels are also sent by USB to a host PC where they can be used as a source of random entropy. Power is supplied over the USB cable.
is in a Scylla or Charybdis scenario. If China continues to inflate it
will overheat. If it doesn't, unemployment and unrest will soar, and
the economy will implode. Either way, there is no winning solution.
oil and environmental pollution compound China's problem immensely.
China is simply on an unsustainable path for many reasons.
Chinese asset bubbles are guaranteed to pop, but as I have said many
times, the timing of such events is unknown. In this case however, I am
more apt to believe sooner, rather than later.
Tetra is a robot mouse having four wheels and an
innovative out-of-the-box design. Recently it completed the “World
Class” maze in 4.7 seconds beating the last year record of 6.4 seconds at 30th All Japan Micromouse
Contest. Unfortunately it couldn’t win as it malfunctioned in the final
stage due to some lighting conditions which affected its tracking, but
we have a video of it breaking the record in trial run.
