I have seen too many sites where cabling was laid en never tested before actual use, which meant locating the cabling and faults was a nightmare.
Be sure to have good (which can be very simple, but more complex when Power over Ethernet is involved) testing hardware and use it during installation. You will thank yourself later.
A few videos that can be helpful:

A while ago I bumped into the below post but forgot which Google Search query brought me to it. Very to the point info at [Wayback/Archive] Optiplex models – Difference between model-series – Dell Community (thanks [Wayback/Archive] Philip_Yip – Dell Community!) Read the rest of this entry »

I have been contemplating on pfSense hardware as there has been a large shortage on that market especially for having more than 2 ports (similar to for instance Mikrotik PoE router unavailability).
If by now I have not found any, I might want to revisit [Wayback/Archive] Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up – CNX Software has 3 RJ45 ports and 2 SFP+ cages.
They found it via this 4 page review:

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):
- github.com/Code52/carnac – Unmaintained, does not work on most applications
- github.com/Phaiax/Key-n-Stroke
- github.com/marius-sucan/KeyPress-OSD – Commercial version available
- https://github.com/Jagailo/YetAnotherKeyDisplayer
- mulaRahul/keyviz – Quite new and looks good
To add to this list (unsorted):
- github.com/nutti/Screencast-Keys – Blender addon
- github.com/AxDSan/KeyPose – free alternative to MousePosé for Windows
- github.com/keycastr/keycastr – macOS only
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:
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:
