Re: Raspberry Pi 4 is not a replacement for a real PC, (as it doesn't have Skype) sorry!

Yeah, but that's just converting PostScript to PDF. Given that PDF is a contrained form of PostScript -- Adobe's PS to PDF tool for Unix is / was called 'distiller' for a reason -- the resources required to do that are significantly less than a rasterising step. Don't worry about it unless it's conv...

Re: Raspberry Pi 4 is not a replacement for a real PC, (as it doesn't have Skype) sorry!

The funny thing is that the Pi 4 I have has 4 times the ram of the x86 laptop it replaced as my daily driver. Given that I have deliberately selected printers that have decent Linux support, the Pi 4 has absolutely zero issues printing. The 3B+ also had zero issues printing. It very much depends on...

Re: Raspberry Pi 4 is not a replacement for a real PC, (as it doesn't have Skype) sorry!

Linux has cups? Linux has CUPS. Never tested Pi printing, what works and what does not? Better on a different thread, is there a printing thread? Dunno. I did setup CUPS on a 2B as a network print server at one point, but had to give up. The rasterisation process consumes a vast amount of RAM, and ...

Re: SSH brute force attacks?

If in doubt, there's a very handy package called fail2ban which will lock IP addresses out of ssh -- using an iptables firewall -- after too many incorrect login attempts. I highly recommend it, and run it on a lot of my machines.

How did you get it to play H265 without X (Raspbian lite)? Possible to show cmds?

In all honesty, you're probably best off just using two uSD cards. Much simpler, although slightly fiddly when swapping them over.

Mount the filesystem on another machine, chroot into it, and run passwd to change the password. This is standard Unix password resetting procedure where you have access to the filesystem.

Re: Raspberry Pi 4 usb boot?

When booting via an SD card, the *correct* /boot partition is always located on the SD card. There's nothing to concern oneself with. The one problem with that approach is that it isn't true in the multiboot environment. The /boot partition also has implications for /lib/modules/ (which will be hos...

Re: Can Pi 4B 4gb emulate Xbox 360?

I very much doubt 4x1500MHz Cortex A72 will get anywhere near 3x3200MHz PowerPC cores, let alone match the GPU requirements (OpenGL vs. (this being Microsoft) DirectX something), particularly under emulation.

JS is still a problem, even in 'good' contexts. Mostly because the browser is tasked with determining between the good and bad, and often fails.
