Still glad I got a few of [WayBack] GL-AR300M – GL.iNet: it makes travel life so much easier when you cannot use tethering.
I got the model GL-AR300M with external antennas (the GL-AR300M only has internal ones with a much shorter range).
Powered over USB, it runs OpenWRT and can NAT a local network towards an external network on the WAN, WiFi or (via USB) 3G/4G modem.
Despite doing only 2.4Ghz, it was a life saver in many occasions (there is a 5Ghz model, but it has over heating issues).

Good to remember both these:
[WayBack] Operant Conditioning by Software Bugs – Embedded in Academia which means when using a system, you subconsciously start behaving around it’s issues. This also happens when you the software you wrote the software for such a system: you hardly test the things that you broke.
The magic SysReq key on Linux systems running on PC-hardware allows you to sync/mount read-only/shutdown a system by keyboard (and many more options – see the Wikipedia list below). Do not forget to enable this as it is disabled by default. And remember that many laptops forego the SysReq key (as do Mac systems).
The order while holding Alt-SysReq down is S,U,B…

Just in case I want to really go off-grid: [WayBack] Li-Ion BMS – Lithium-Ion Battery Management Systems and large battery packs
It has a configuration selector module pointing to companies (even one in The Netherlands) that can help me out.
Via [WayBack] DIY Electric Car Forums – View Single Post – using 18650 cells to make 25kwh battery
Hopefully they are based on 18650 batteries:

Thomas Rini (of U-Boot and Yocto fame) mentioned these solutions for remote power control of IoT devices and remote updating SD cards in this slide State of the U-Boot – Thomas Rini, Konsulko Group:
- FlashAir WiFi enabled SD cards
Two power solutions I like myself are:
The combination of these allows for really flexible production and testing environments.

I am still a bit ambivalent on remapping keys on a keyboard, mainly because of two reasons:
- Without remapping, tools used for virtualisation, remote access and shells already get it wrong every now and then. Finding causes is already tough, so adding more degrees of freedom complicates this more.
- Switching systems or assisting people without the tools can be cumbersome. I vividly remember the really hard times when I had switched from Windows Explorer to Windows Commander (now Total Commander) and could not use it on a sequence of contracting jobs.
Just in case I am going to use it:

[WayBack] RB450G and “..could not get answer from dns server” – MikroTik: I do not see a default route. It would be the route with “dst-address=0.0.0.0/0“.
