https://access.redhat.com/blogs/766093/posts/3031361?sc_cid=7016000000127ECAAY The SSL/TLS protocol uses RSA, Diffie-Hellman (DH) or Elliptic Curve Diffie-Hellman (ECDH) primitives for the key exchange algorithm. RSA is based on the fact that when given a product of two large prime numbers, factorizing the product (which is the public key) is computationally intensive, but a quantum computer could efficiently solve this problem →
https://m.youtube.com/playlist?list=PLJO4AtxKJiFMa-xhNLNpp-URxQH-7Ka6Q This YouTube playlist shows videos of interesting hardware plus software hacks. They can play computer demo multimedia with old game consoles, Arduino+LED sign, LEGOs and audio mixer… Many cool hacks I would say! Assembly Summer 2017 event is still going on, more videos at AssemblyTV at YouTube and Assembly Summer 2017 pages. →
RF attenuators are a universal building block within the RF design arena. I neeeded some RF attenuators for my electronics lab. I found this cheap product DC-4.0GHz RF Fixed Attenuator from Banggood. They seemed to have pretty good specfications and features considering that the price is just slightly over 7 Euros for three attenuators: Frequency →

https://techcrunch.com/2017/08/03/edge-computing-could-push-the-cloud-to-the-fringe/?utm_source=tcfbpage&sr_share=facebook I can believe in this vision! Edge computing could push the cloud to the fringe Peter Levine believes that cloud computing is soon going to take a back seat to edge computing — and we will very quickly see the majority of processing taking place at the device level. As crazy as that sounds — and →
The Rane Library has many interesting audio relaed technical documents. The most famouse of them is Note 110 Sound Systems Interconnections – it is a classic. Just few days ago I happened to look around at The Rane Library, and found some really interesting material related to audio systems and ground loops: Grounding and Shielding →
https://petapixel.com/2016/07/28/camera-adds-10-pounds/ It’s commonly said that a camera adds 10 pounds, making you look heavier than you actually are. It’s “amazing how focal length affect shape of the face,” writes photographer Dan Vojtech, who shot this series of portraits at different focal lengths to show the effect. →

This question comes up time and again. Many say no, fewer say yes – who’s right? This article is from few years back, but still is valid. Besides RF applications you need to consider material with very →
