Awesome Watches...Seriously


These are no ordinary wrist watches. These are watches that tech-savvy people should have on their wrists but only if they the cash in their pockets or banks cause these time-giving masterpieces are not for the unfortunate.

The Tread 1 is no ordinary watch . According to Devon, it is made by a patented system called Interwoven Time Belts but reinvented.This what gives the belt it's singularity. The belts are powered by compact microstep motors providing power and accuracy, which is the important to watches. Counting 86,400 seconds per day is a task that human bestowed upon watches, certainly not an easy task. The watch is powered by a lithium polymer battery and one charge will last you a couple of weeks.


The son of a famed French watchmaker Jorg Hysek, Jorg Hysek Jr, design the stylish and awesome if I do say so myself the HD3 Slyde which has an LED screen with a sapphire crystal cover that curves to conform to your wrist. With no physical buttons, the watch has just three battery indicator lights on the side and a light sensor to automatically adapt the brightness of the screen. Everything is controlled by taps or slides on the touchscreen. So high-tech indeed.




Worldwide LHC Computing Grid






A considerable amount of people of Earth somewhat have heard about the Large Hadron Collider which is presently located in Cern, Geneva. Although the existence of such massive scientifically significant mega structure is known by a lot of people, very few are aware of one question :
If the Large Hadron Collider is collecting a lot of data for better understanding physics, what kind of supercomputer is managing the data?

The answer to that question resides in grid computing. Grid computing is unlike super computer.They are super virtual computer. A supercomputer are resources such as computers or processors connected via high speed system bus whereas super virtual computer are connected via high speed networks.

What is the Worldwide LHC Computing Grid?



The Worldwide LHC Computing Grid (WLCG) is a distributed computing infrastructure to provide the production and analysis environments for the LHC experiments.

It is managed and operated by a worldwide collaboration between the experiments and the participating computer centres. The resources are distributed across the world for funding and sociological reasons.

WLCG is therefore a distributed, or grid-based, infrastructure - the most effective solution for meeting the data analysis challenge on this unprecedented scale.

Currently WLCG is made up of more than 140 computing centers in 35 countries to process, analyze and store data produced from the LHC, making it equally available to all partners, regardless of their physical location.

Tiers

The WLCG is composed of four levels, or “Tiers”, which are made up of the computer centres. The tiers are called Tier 0, Tier 1, Tier 2 and Tier 3. These tier sites process, store and analyse all the LHC data between them.

Components

Massive multi-petabyte storage systems and computing clusters with thousands of nodes connected by high-speed networks are the building blocks of the WLCG centres.

Data processing

The challenge of analysing the volume of data produced at the LHC is an immense task. Two-stage processing using dedicated algorithms are in continuous development to reduce data 'noise', and assist in focusing on the most important data which could bring new physics discoveries.


Sadly, not enough info for the supercollider's super virtual computer since it is kept secret so that other competing organizations may reproduce such a scientific marvel but recently, the supercollider's committee decided to ask for public help to connect their pc's to the grid for extra resources.

AES Encryption


Ok guys, its been awhile since I last posted anything here but to avoid any nagging from admin I decided to up the ante for my next post. Here for all who is interested about encryption and computer security, a brief explanation about one of the basic encryption algorithm that all of them whom call themselves |-|4xx0|2 (if you don't what is this go learn about 1337). AES is simple in terms of implementation but complex in terms of production. Both simplicity and complexity is one the requirements for the AES when it was first proposed. I have to warn you th at this kind of stuff is not for the weak hearted and mind (seriously). This is a very complex thing but I know some people would have no trouble understanding.

The Advanced Encryption Standard (AES) is an encryption algorithm for securing sensitive but unclassified material by U.S. Government agencies and, as a likely consequence, may eventually become the de facto encryption standard for commercial transactions in the private sector. (Encryption for the US military and other classified communications is handled by separate, secret algorithms.)
In January of 1997, a process was initiated by the National Institute of Standards and Technology (NIST), a unit of the U.S. Commerce Department, to find a more robust replacement for the Data Encryption Standard (DES) and to a lesser degree Triple DES. The specification called for a symmetric algorithm (same key for encryption and decryption) using block encryption (see block cipher) of 128 bits in size, supporting key sizes of 128, 192 and 256 bits, as a minimum. The algorithm was required to be royalty-free for use worldwide and offer security of a sufficient level to protect data for the next 20 to 30 years. It was to be easy to implement in hardware and software, as well as in restricted environments (for example, in a smart card) and offer good defenses against various attack techniques.
The entire selection process was fully open to public scrutiny and comment, it being decided that full visibility would ensure the best possible analysis of the designs. In 1998, the NIST selected 15 candidates for the AES, which were then subject to preliminary analysis by the world cryptographic community, including the National Security Agency. On the basis of this, in August 1999, NIST selected five algorithms for more extensive analysis. These were:
  • MARS, submitted by a large team from IBM Research
  • RC6, submitted by RSA Security
  • Rijndael, submitted by two Belgian cryptographers, Joan Daemen and Vincent Rijmen
  • Serpent, submitted by Ross Andersen, Eli Biham and Lars Knudsen
  • Twofish, submitted by a large team of researchers including Counterpane's respected cryptographer, Bruce Schneier
Implementations of all of the above were tested extensively in ANSI C and Javalanguages for speed and reliability in such measures as encryption and decryption speeds, key and algorithm set-up time and resistance to various attacks, both in hardware- and software-centric systems. Once again, detailed analysis was provided by the global cryptographic community (including some teams trying to break their own submissions). The end result was that on October 2, 2000, NIST announced thatRijndael had been selected as the proposed standard. On December 6, 2001, the Secretary of Commerce officially approved Federal Information Processing Standard (FIPS) 197, which specifies that all sensitive, unclassified documents will use Rijndael as the Advanced Encryption Standard.
The Advanced Encryption Standard (Rijndael)
The block cipher Rijndael is designed to use only simple whole-byte operations. Also, it provides extra flexibility over that required of an AES candidate, in that both the key size and the block size may be chosen to be any of 128, 192, or 256 bits. (During an early stage of the AES process, a draft version of the requirements would have required each algorithm to have three versions, with both the key and block sizes equal to each of 128, 192, and 256 bits. This was later changed to make the three required versions have those three key sizes, but only a block size of 128 bits, which is more easily accomodated by many types of block cipher design.)
The original description of Rijndael is available at: http://www.esat.kuleuven.ac.be/~rijmen/rijndael/.

However, the variations of Rijndael which act on larger block sizes apparently will not be included in the actual standard, on the basis that the cryptanalytic study of Rijndael during the standards process primarily focused on the version with the 128-bit block size.
Rijndael is a relatively simple cipher in many respects.
Rijndael has a variable number of rounds. Not counting an extra round performed at the end of encipherment with one step omitted, the number of rounds in Rijndael is:
  • 9 if both the block and the key are 128 bits long.
  • 11 if either the block or the key is 192 bits long, and neither of them is longer than that.
  • 13 if either the block or the key is 256 bits long.
To encipher a block of data in Rijndael, you first perform an Add Round Key step (XORing a subkey with the block) by itself, the regular rounds noted above, and as already noted, the final round with the Mix Column step, as described below, omitted.

Now that you know a bit about this type of encryption, here is an example of what the encryption looks like kinda. You can download a pdf from:

Direct Download Skills

Imagine if there is a way to learn new things by directly download the new things into your brain.

Recently, experiment conducted by Boston University and ATR Computational Neuroscience Laboratory in Kyoto, Japan, has successfully demonstrated through stimulation on a person's visual cortex, one would be able to improve his/her own performance on visual tasks.


The researchers used decoded functional magnetic resonance imaging in order to induce a brain activity pattern from a previously determine state in a person. The method is believed can be used in inserting new knowledge through the visual cortex, eliminating the need for practice and hardwork.


Below is some description about this experiment according to NSF. Read full NSF press conference about this project here.

"Think of a person watching a computer screen and having his or her brain patterns modified to match those of a high-performing athlete or modified to recuperate from an accident or disease. Though preliminary, researchers say such possibilities may exist in the future.

Neuroscientists have found that pictures gradually build up inside a person's brain, appearing first as lines, edges, shapes, colors and motion in early visual areas. The brain then fills in greater detail to make a red ball appear as a red ball, for example."


In the press conference, Watanabe, one of the co-founder in this project said;

"The most surprising thing in this study is that mere inductions of neural activation patterns corresponding to a specific visual feature led to visual performance improvement on the visual feature, without presenting the feature or subjects' awareness of what was to be learned."

Though the project still has few limitations, this undoubtedly allows a new method of learning which can be beneficial for all mankind. Imagine having able to learn about stuff by just connecting yourself to a computer. Much like this:


I sincerely hope this i could get my hands on being the subject for this. Nevertheless, hopefully the project can give a lot of benefit to people with problem in studying.

Amondawa Tribe

You probably have never heard of Amondawa tribe, but this tribe has given scientists chaos in their theory that time was deep-rooted in human brain.


Amondawa tribe, is believed to not have the concept of time. The concept of time is so loss that they did not have words for "year", "week", "month". According to Chris Sinha, a professor at the University of Portsmouth, Amondawa people live in a world of events without embedding the time in the event like normal human should, or at least, normal to us. 


This people, rather than splitting day into specific part like morning, evening, afternoon or night, they just have two, day or night! Their season is also divided into two, rainy and dry.


Well, living without the concept of time certainly can benefit us in some way, but can you imagine if time does not exist??

The Accurate

For most people, living in constant fear may not be good, and for these people, the watch below might not be suitable for them. 

But people in some religion, especially Muslims, they will need this constant reminder because without this reminder, they may fall out of their religion's way of life. 


Design by Mr Jones Watches (MJW), the watch, which is called The Accurate, is designed so that the hour hand reads "remember" and the minute hand reads "you will die". 





You can get the watch at $157 and for special black edition, $167.
