A 'channel' is a named version stream of a particular operator. An operator 'catalog' is a collection of operators and channels.)

Thanks for this. The Segger J-Link EDU and EDU Mini are cheaper versions of the J-Link BASE JTAG-and-SWD debug probe aimed at the hobbyist for non-commercial use. https://www.segger.com/products/debug-probes/j-link/models/j-link-edu/ https://www.segger.com/products/debug-probes/j-link/models/j-link-edu-mini/ I had discovered https://www.xjtag.com/about-jtag/what-is-jtag/ to try and find out about this. Software bugs kill but software testing tends to only check things work, not how things can break. Competent code inspection can spot the latter. https://en.wikipedia.org/wiki/Therac-25 When I was teaching my thing about testing was that it was not just about testing to see that it did what it was supposed to, but also to see that it didn't do what it was not supposed to. The example of this was software from my previous employer that only accepted valid dates, and the stuff we got from the Americans that would accept 00/00/00 and 99/99/99 for dates. -- Next meeting: Online, Jitsi, Tuesday, 2023-01-03 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

[Dorset] Links from 2022-12-06's Pub Meet.
Hi,
The Government's Project Gigabit aims to increase good broadband to
rural areas. https://projectgigabit.campaign.gov.uk/
Though I don't think Hugh's eligible because...
https://gigabitvoucher.culture.gov.uk/#suppliers
‘Vouchers in your area have been paused as your address may shortly
be included in one of our Project Gigabit contracts. This could
mean your home is in line for gigabit broadband without the need for
a voucher. Please check back in a few weeks’ time for any further
updates.’
That page then lists three suppliers in the area.
Jurassic Fibre, another local supplier installing equipment beneath the
pavements. https://jurassic-fibre.com
The Segger J-Link EDU and EDU Mini are cheaper versions of the J-Link
BASE JTAG-and-SWD debug probe aimed at the hobbyist for non-commercial
use.

A nascent Mastodon instance. https://dorset.social
Use fail2ban to monitor a single file for a particular string and run a
certain command each time it appears. https://www.fail2ban.org
Or build it yourself. This is Unix.

FreeRTOS has had backing for a while now from Amazon which wants to
speed the development of IoT devices which may then use AWS. It's a
good easy RTOS to get started with. https://www.freertos.org
A rival from The Linux Foundation is Zephyr. It has backing from the
likes of Intel, Nordic, and NXP who contribute device drivers and other
work. Its configuration and build system is a bigger initial hurdle
though. https://zephyrproject.org
Software bugs kill but software testing tends to only check things work,
not how things can break. Competent code inspection can spot the
latter. https://en.wikipedia.org/wiki/Therac-25
Unified Modeling [sic] Language is at the end of a long lineage of
systems for using diagrams to analyse requirements, develop software,
and document behaviour. It grew out of the Object Orientated movement.
