This was a cool post: [Wayback/Archive] 433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors – CNX Software
433MHz LoRa Transceiver-based ESP32 board work with regular 433 MHz sensors found on the market. This gives end users a simple off-the-shelf solution for receiving these signals without having to use a soldering iron and making a circuit.
…
This opens many doors regarding 433 MHz sensor readings with one device, including weather stations, doors, PIR, TPMS, temperature, and BBQ sensors.
Recommended reading!

Two kinds of RP-SMA dual-band WiFi antenna parts having :
- Y9MPH is an omnidirectional dipole stick antenna which most use
- 3TJ9N is a semidirectional patch/panel antenna on a wire which few people use but can be useful when you want to put the antenna into a place having better signal reception
Both are also supposed to work for Dell OptiPlex Micro models 3020/3040/3050/5020/5040/5050/7020/7040/7050 (as 5030/7030 models were never released and 3030/9030 only released as a different all-in-one PC form factor): basically the end of the Micro form factors in Dell OptiPlex Series 4 and start of Dell OptiPlex Series 5.

In a German thread, Kristian Köhntopp perfectly explained why I too always use light mode, so I put the English translations here:
- Dark mode is a strain on the eyes and useless.
- Specific: In darkness (and in dark mode) your pupils widen, the diaphragm opens. This reduces the depth of field and the eye muscles have to do more work and precision when focusing.
- Conversely, with light and a bright background you have a smaller pupil, a small aperture and more depth of field. This means that everything is automatically sharp, even if the eye has not readjusted.
The German thread:

Voor mijn link archief: KPN telefooncentrales, waarvan een paar waar familie of ik een aansluiting had:
[Wayback/Archive] Wijkcentrales – VVDSL.robinflikkema.nl
Deze hadden Mojibake met de generic replacement character (“�”):

A lot of people publish unattributed copies of the cartoon “Yes the planet got destroyed. But for a beautiful moment in time we created a lot of value for shareholders.”, so I tried finding it back.
I found out that the Google Image Search has deteriorated to the point where it could not find the 2012 original.
Luckily [Wayback/Archive] Yes the planet got destroyed. But for a beautiful moment in time we created a lot of value for shareholders. – Google Suche did find the original.
So, without further ado, these are links, the original cartoons by [Wayback/Archive] Tom Toro, first published in The New Yorker:
