Do not pay for premium accounts, use their freemium service to death! Let them die hard!

Excuse me for being ignorant, is Seccomp what SELinux is based on ?

Also, what is well-known piece of software that uses Capsicum on FreeBSD ? Can someone name a few ?

When I was watching that Lunduke's video a couple of days ago initially I was thinking he's just making a joke of that Vendefoul Wolf distro on 200MB box. I recalled using FreeBSD as access server with lots of modems (PPP/SLIP), Apache, Samba and QuakeWorld server running on a box with just 32MB of RAM. That was also my daily working machine with XF86 and Enlightenment desktop manager, circa 2000. So, 200MB is a whole lot of memory!

That's interesting, thanks. I feel a need for simple multitasking/networking OS for synthesizable RV32I core (not RTOS like, but more like Unix or CP/M). Would be nice to try Plan9 on it once port is out.

I use one written in SpinalHDL. :-)

Next question is how much RAM it needs to boot and can it be used without rio ?

Is there Plan9 port for RISC-V (RV32I) ?

Ice hockey player also here. Defence. Pretty neat analogy with Google. :)

Did you see tamatoes harvested that way ? They are suitable only for producing sauce.

Get two FTDI FT232RL chips, connect them together on serial side (RXD->TXD, TXD->RXD, GND<->GND). Plug into USB ports of your computers, run terminals (or any other software that supports serial I/O), send/receive data. Can use XYZModem to send files, PPP for TCP/IP networking, etc. No programming involved. Cheap as hell.

Right. But I would still prefer markdown file format, so I could simply open it in web browser. :)

How about social.md which is gpg signed ?

Nice reading. But...

What's wrong with this guy and Git ?

How does F8 compare to RV16 in terms of resources (die size) used and performance ?

You don't need that much of energy to keep CMOS memory and RTC clock running. The battery will self-discharge way before it's exhausted by the load. IMHO.

Supercaps don't not leak and do not require to be changed regularily. Yes, offline time on supercap would be small, a couple of months, but for a machine which is used often that is not a problem.

Why not use a 5F/5V supercapacitor, DGH505Q5R5 or anything alike ? You may need to solder a 10R current reducing resistor in series.

Still not possible to use same sketch for extruding multiple solids. :( I used to this feature in F360 a lot.

Lattice's FPGAs are very nice. With an iCE40 you can have a full featured RISC-V soft-core (RV32IMFAC) at some 80 MHz.
