Cyber security trends for 2021

Nothing is more difficult than making predictions. For this reason I did not do any “predictions for 2021 cyber security” posting before year 2021 started. Instead of trowing out wild ideas what might be coming, I have collected here some trends other people have predicted or reported. The State of internet security in 2020 was

Raspberry Pi Pico board

Interesting new micro-controller board and custom chip from Raspberry Pi: Raspberry Pi Pico. Pico provides a single push button, which can be used to enter USB mass-storage mode at boot time and also as a general input, and a single LED. It exposes 26 of the 30 GPIO pins on RP2040, including three of the

This year CES 2021 was a digital venue showed newest innovation in consumer electronics. It had some 1900 virtual booths, several peripheral product showcase. Here are some links to reports on the

ECC memory on PCs

Error-correcting code memory (ECC memory) is a type of computer data storage that can detect and correct n-bit data corruption which occurs in memory. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, like industrial control applications, critical databases, and infrastructural memory caches. ECC protects against undetected memory

Desoldering iron

In electronics, desoldering is the removal of solder and components from a circuit board for troubleshooting, repair, replacement, and salvage. There are many techniques how to desolder. Check out videos How to Desolder Through-Hole Parts, Why Some Joints are Difficult and Desoldering Components – Tips and Tricks. Desoldering tools and materials include the following: Solder

Grid tie inverter technology

A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, normally 120 V RMS at 60 Hz or 240 V RMS at 50 Hz. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid. They range from small
