Emergency over coronavirus

I am living in the middle of the emergency over coronavirus in Finland. Due this reason the update cycle to make posting to this blog could be slowed down. The Finnish government announced on Monday nationwide school closures in order to help prevent the spread of coronavirus. Read more on the following aricles: Finland closes

Signal processing tips from Hackaday

Signal processing is an electrical engineering subfield that focuses on analysing, modifying and synthesizing signals such as sound, images and biological measurements. Electronic signal processing was first revolutionized by the MOSFET and then single-chip digital signal processor (DSP). Digital signal processing is the processing of digitized discrete-time sampled signals. Processing is done by general-purpose computers

Signal generator FY6800

A signal generator is an electronic device that generates repeating or non-repeating electronic signals in either the analog or the digital domain. These generated signals are used as a stimulus for electronic measurements. There are many different types of signal generators with different purposes and applications. For analogue signal generation I have used for very

Intel hardware trust is lost again?

Yet another bad sounding Intel processor security vulnerability is released and this could be big again. Little over two years ago I wrote about Meltdown and Spectre, and posted links to some following vulnerabilities. Now an article Intel x86 Root of Trust: loss of trust from Positive Technologies details a new vulnerability. Researchers at enterprise

Nasty Linux PPPD vulnerability

This looks like a nasty vulnerability. It seems that a newly found critical 17-years-old remote code execution (RCE) vulnerability could open nearly all popular #Linux based operating systems and many embedded devices to remote hackers. Many widely-used Linux distributions have already been confirmed impacted. Hacker news writes: The US-CERT today issued advisory warning users of

Cheap DDS Function Generator

Years ago you had to either build your own signal generator or buy usually a quite expensive signal generator. Lately there has been a push for very cheap ($15-25) digital function generator kits available from China. I wrote about some interesting function generator devices few years ago, and here is a closer look to one
