Fitting switched sockets has been "the done thing" in the UK for many years, but it's not actually a regulation.

If they don't take the VAT off for non-Europeans you should be able to reclaim it from Her Majesty's Revenue & Customs (HMRC). Are you sure? thats the first I have heard anything like that!

Re: how does the pi keep track of time without a real tine clock

First some terminology, most computer have two clocks, the "system clock" is implemented in the OS based on the processor's internal timers, this clock has high precision but only ticks while the system is running. The "hardware clock" or "rtc" is a seperate low power clock with a battery used to ke...

Re: FreeCAD on PI4 and Raspbian Buster.

Looking at this. Freecad 0.16 was in Debian and raspbian stretch. It seems freecad 0.16 was removed from Debian buster back in 2017 and was probablly removed from raspbian buster around the same time. I have not researched exactly why but I would guess it was broken in some way. 0.17 made it's way b...

Typically on Debian systems they used to (possibly still do) use "stable" instead of the release name ("stretch", "buster" etc) in the sources.list files.
They used to, but nowadays the Debian installer uses release codenames.

Re: Raspberry Pi 4 Thread - general discussion

Worry not - HDMI can support non-HDTV resolutions too. It can support 640x480, 800x600, 1024x768, 1280x720, 1280x800, 1366x768 etc. NM brainfart, I was confusing 1440x900 (which is fine on single link DVI or older versions of HDMI) with 2560x1440 (which needs dual link DVI, displayport, or HDMI 1.3...

Re: Raspberry Pi 4 Thread - general discussion

The big question I would think with such monitors is whether the monitor supports it's full resoloution over HDMI or not.

IIRC HDMI was only recently upgraded to support high-res (> 1600x1200) monitors, so older monitors may only support their full resoloution on displayport or dual-link DVI.

As I read the spec, the only USB present is connected via PCIe, the single USB port avialable on older iterations of the SoC isn't present on the Pi4.
The old USB controller is still present on the SoC. On the 4B it's connected to the USB C connector.

USB boot is not currently supported on pi4. It's on the list for a future firmware update (unlike earlier models the pi4 has updatable boot firmware).

Re: Buster upgrade fails

I just tested that mirror from here, for me it seemed to be working but very slowly.

I have disabled it's entry in the mirror redirection system for now, so if you try again you should be directed to a different mirror.

The pi4 has added a bunch of new GPIO alternates. Is there any plan for a naming scheme to avoid confusion between addon boards that are pi4 only and boards that work with all pi models?
