Now available from GNU Press, the NeuG True Random Number Generator
This week I had a chance to add a NeuG, a True Random Number Generator, to the Free Software Foundation network. The NeuG exclusively uses free software and was developed in Japan by NIIBE Yutaka. A random number generator (RNG) is a device used to generate random numbers for computers. Without getting into a philosophical argument, we humans tend to take the concept of entropy (randomness) for granted. If we wish to produce random data, we simply do so. Computers, on the other hand, do as we tell them to do. They follow a set of instructions provided by a programmer and follow each instruction precisely. So there is no way to ask a computer to give us a random number because we would have to tell the computer in advance what the number is. There are some ways around this. For example, we could use a system's current timestamp as a seed, or starting point, for producing random-seeming numbers by using an algorithm. This approach will create the illusion of entropy, but if someone else knows both the timestamp used for the seed and the algorithm used to generate the random numbers, the sequence of the random number generator can be calculated and predicted.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
