Dennard scaling – Wikipedia
Since around 2005–2007 Dennard scaling appears to have broken down. As of 2016, transistor counts in integrated circuits are still growing, but the resulting improvements in performance are more gradual than the speed-ups resulting from significant frequency increases.[1][10] The primary reason cited for the breakdown is that at small sizes, current leakage poses greater challenges and also causes the chip to heat up, which creates a threat of thermal runaway and therefore further increases energy costs.[1][10] Since 2005, the clock frequency has stagnated at 4 GHz, and the power consumption per CPU at 100 W TDP.

This is a reminder to check if this below late 2019 proposal inspired by Visual Studio Code Screencast mode¹ already made it: [Wayback/Archive] Overlay of commands / shortcuts / keys pressed – Screencast Mode · Issue #981 · microsoft/PowerToys · GitHub which mentions some tools that can already do this
Here is a list of FOSS apps that currently do this (sorted by stars):
To add to this list (unsorted):
In the meantime, I am using Key-n-Stroke as it is the only still supported one I found that is easily turned off/on when typing sensitive content like passwords:

I wasn’t aware that [Wayback/Archive] [OpenWrt Wiki] MikroTik was available. Many devices are incomplete in support, but it is good to know there is an alternative to the buggy scripting interface of RouterOS.
For the hEX series, support seems good enough to give it a try this summer, but I need to figure out of the hEX PoE RB960PGS is supported. I have good hopes as other models of the RB9* series are.
A few warnings from the below links:
- First Things First: Don’t Lose Your RouterOS License
- OpenWrt is not compatible with the bootloader of RouterOS v7. Do NOT upgrade the firmware on your device to RouterOS v7 or, if you did, downgrade to RouterOS Firmware v6 before installing OpenWrt. RouterOS doesn’t allow to downgrade below factory firmware version, but OpenWrt boots and works fine with versions up to 6.49.10 or beyond. Confirmed working: 6.47.10 (tested on SXTsq 5 ac), 6.49.10 (tested on SXTsq 2nD).
- If the installation fails, you might need to upgrade/downgrade to RouterOS 6.49.2
- Warning: Don’t upgrade RouterOS packages & bootloader to 7.2.1 otherwise ‘sysupgrade image’ install will fail!
- If latested release of RouterOS does not work, try an older version. 6.45 is reportet to work as a first debrick, you can upgrade later with the Winbox Software to latest release
These hEX related models are supported on the web-site (which also explains major differences with Fast Ethernet (100 Mbit/s) and Gigabit Ethernet (1 Gbit/s) models:

It was pretty hard to find any model/part-number information on optional video boards for the Dell 3060/5060/7060 Micro series (also known as Regulatory Model D10U and Regulatory Type D10U003).
These models by default had HDMI (version 1.4) and full-size DisplayPort (version 1.2) and additionally could ship with these configurations:
There was (seems not available any more) a serial port (:
Further below are some links I found, but first a ink to a good post on differences between 3060/5060/5070:

Your Ring Video Doorbell 2 is charged using a common micro-USB cable (an orange one is included in your Ring box). The micro-USB cable can be plugged into any USB power source such as a computer. Your Ring Video Doorbell 2 will take around five to 10 hours to fully charge depending on whether the USB cable is plugged into a USB port or into a wall outlet.

Will need this: [Wayback/Archive] Centurion Deuren: Gebruikers- & Installatiehandleiding KS-Serie (70 – 100) [Wayback PDF View/PDF View]
The problem is that a combination of the buttons of the Centurion remote controls failing more frequently plus that the remote control are unable to teach their code to new universtal remote controls that we still had from our previous home which used a Marantec door.
Universal remote controls are supposed to be compatible with both Centurion and Marantec remote controls.
What I want to figure out is if I can initiate one new remote control from the door opening mechanism, then have that teach other new remote controls.
Hopefully this is the right manual for the model we have (the model number is not visible from below, so need to verify that from a location difficult to look from above).
Fingers crossed.
