Sunsetting Python 2 | Python.org

https://www.python.org/doc/sunset-python-2/ Volunteers who make and take care of the Python programming language have decided that January 1, 2020, will be the day that we sunset Python 2. That means that the people who develop python will not improve it anymore after that day. Even if people find catastrophic security problems in Python 2, or in

Stibitz demonstrates remote computing, September 11, 1940

Interesting historical facts according to https://www.edn.com/electronics-blogs/edn-moments/4395946/Stibitz-demonstrates-remote-computing–September-11–1940: George Stibitz of Bell Telephone Laboratories used his Complex Number Calculator (CNC) to demonstrate remote computing for the first time on September 11, 1940. Stibitz was among a handful of engineers across the globe designing machines that involved using relays to implement binary logic at the time. You can

Microphone hardware hacking with a hammer

I have had for a long time an AKG D60 S microphone. The AKG D60S is advertised as an unidirectional semiprofessional dynamic microphone with smooth frequency response, a rugged all-metal body, an on/off switch, and removable wire-mesh grill.  It was proven to be a decent semiprofessional all-round microphone with hypercardioid polar pattern. Hypercardioid microphones are

Friday Fun: More oscilloscope art

It’s cool to see a functional tool like the oscilloscope manipulated to display unrelated art. When you input suitable stereo audio into an old scope in in X-Y mode, you can see all kinds of artistic creations. Salvaged Scope Lets You Watch the Music article introduces you how to use old scope for video art.

IoT interoperation lies

We were promised Intenet of Things interoperability on sales pitch, but we seem to end up is living with landfill full of proprietary shot-lived wallet gardens of crappy things. “But that Google can suddenly decide to sunset a cloud API that hundreds of IoT devices have been talking to for less than five years is

Proposed LED/wired IoT standard can reduce energy use

While switching to LED lighting certainly helps reduce power consumption, we can do more. Each conventional mains powered LED bulb has its own AC/DC power supply, which is needed for bulbs to be compatible with AC wiring and lighting fixtures with sockets designed 100 years ago. Having individual power supplies adds cost and decreases efficiency

Cyber security news September 2019

This posting is here to collect cyber security news in September 2019. I post links to security vulnerability news to comments of this article. If you are interested in cyber security trends, read my Cyber security trends 2019 posting. You are also free to post related links.    

AI/ML in microcontrollers

Zach Shelby from ARM tells in this article that we can already run meaningful machine learning inference on Cortex-M equivalent microcontroller hardware. How we can utilize that in our future hacks? https://blog.hackster.io/embedded-ml-for-all-developers-1f000ccdaddd I saw Zach Shelby few months ago telling how to do that in conference, tried one demo myself and talked him in person.
