How to build a Tesla Coil. Electrical / Electronics Conversions Formulas & References - RF Cafe. Throughout the years as an engineer, I have needed to research topics on engineering, physics, chemistry, mechanics, mathematics, etc. The Internet has made the job infinitely simpler, with the caveat that you have to be careful of your sources. Anyone can post anything on the Internet without peer review, and errors are rampant. The topics listed below are primarily ones that I have researched and generated custom pages for the content. I welcome visitor review and comments on my material to help ensure accuracy. - NIST's Reference on Constants, Units & Uncertainty - U.S. An Overview of Cryptography. As an aside, the AES selection process managed by NIST was very public.

A similar project, the New European Schemes for Signatures, Integrity and Encryption (NESSIE), was designed as an independent project meant to augment the work of NIST by putting out an open call for new cryptographic primitives. NESSIE ran from about 2000-2003. While several new algorithms were found during the NESSIE process, no new stream cipher survived cryptanalysis. As a result, the ECRYPT Stream Cipher Project (eSTREAM) was created, which has approved a number of new stream ciphers for both software and hardware implementation.

Similar — but different — is the Japanese Government Cryptography Research and Evaluation Committees (CRYPTREC) efforts to evaluate algorithms submitted for government and industry applications. CAST-128/256: CAST-128, described in Request for Comments (RFC) 2144, is a DES-like substitution-permutation crypto algorithm, employing a 128-bit key operating on a 64-bit block. 3.3.

Home improvement projects. Personal and Historical Perspectives of Hans Bethe. 12 Unique Email Services You Should Know About. 45 Free Online Computer Science Courses. 99 of the Best Windows Freeware Programs You May Not Know Of.

Due to the popularity of my previous article on Help Desk Geek entitled 99 ways to make your computer blazingly fast, I’ve decided to write another list post with 99 items, but this time on Windows freeware programs that you may have not heard of. If you search for “best freeware programs” or “top freeware apps”, you’ll get lots of lists, but mostly with programs everyone has already heard of: AVG anti-virus, 7-zip, Firefox, OpenOffice, etc., etc. That’s all nice and fine, but what about all those little gems programs that work great, but don’t get all the headlines?

In this article, I will try my best to mention as many small name freeware programs as I can that can help make you more productive! It’s a long list, so feel free to bookmark it and refer to it later on. These are written in no particular order! Again, I’m sure there are hundreds of programs that I won’t mention, so if you feel I’ve really missed a great program, mention the name of the app and what it does in the comments!
