Re: Upside down text

Just checking, it's still there and really funny. bing.com/covid It's showing 'United State' instead of States. It restores to normal as you zoom in/out but reverts to upside down as soon as you stop zooming. Also, the text shows Mexico as NORTH of the US, and Canada as SOUTH. So it's the text overl...

Upside down text

Pi OS 32bit on a RazPi 4 w/4 G. Upgraded 2 days back on this site http://bing.com/covid which does not seem graphically exacting, The world map text is upside down :o It reverts but 99% stays down.

As they say here "Whassa SStory?" (= What is the story?).

Re: Raspberry PI Hotspot is slow

I made some progress on this, so I'll post my results. Slow downloads is a classic case of aerial interference. The Pis transmit their uploads. I tried everything - firmware, modules, kernels, hardware research. Broadcom use the prefix BCM for their parts, and Cyrpess semiconductor uses CY. Interest...

Re: Slow internet speed on PI 4

Funny thing is, I have the 64 bit beta(?) here, and that's faster than the 32bit one. Around the same time
[*]32Bit Pi OS(armhf) 7-12 Mbps
[*]64bit Beta - 20 Mbps
x86_64 Laptop - 35 Mbps
Android phone - 45-50 Mbps

Re: FPGA Development Software for RPI 4?

This isn't strictly an 'RPi 4' question, is it? More an electronic one. My experience is more with VHDL, but I very much doubt if Verilog handles it. VHDL certainly doesn't. As an Electronics hardware guy, I can tell you implementing tenary logic is difficult in practise, and much slower than conven...

Re: Netflix on Raspberry Pi 4

From my regular fooling with Slackware Multilib, this is not for the faint of heart. You can't just shove in a 32bit program on a 64bit OS. That's the bottom line. Explanation follows: Slackware64 can run 64 & 32 bit libs, but they keep them separate. In Slackware /lib &/usr/lib are for 32bit libs, ...

Re: Getting shock from micro hdmi port when connected to tv hdmi port

You're right - it's badly organised. Most lethal shocks are left --> right hand, or left arm --> right (& perhaps left) foot, because that way, they pass through the heart. It's important to note that 110/120V systems are in fact ±55V/60V with reference to earth. This means 110V only appears between...

Re: Netflix on Raspberry Pi 4

The fix is acquiring a current WideVine library (libwidevine.so). In theory you should be able to take it out of any 64 bit image. With an appropriate library and user agent string it should work. @ventz just extracted the library and packaged it all up nicely in a script. Agreed. Very good of @ven...

Re: Netflix on Raspberry Pi 4

I can confirm it doesn't work on the 64 bit thing. You download a 32bit lib :-/. The error I get blamed the Chromium (Media) desktop in /usr/share/applications. It was owned pi:pi while the rest were root:root. I tried changing them but no dice.

I'm interested in what you are doing but am still totally confused (I don't understand hardware). What you seem to be talking about is a 10Mbps serial link without a synchronising clock. i.e. one end is transmitting 1s and 0s and the receiver could sample every 50ns (bit mid-point) to see if the cu...

So the signal is going to be broadband and well over 10GHz? Erm. Good luck! edit: no, sorry, so you're sampling at ~10GHz? I think you're still going to struggle with that for the pi. No, 10Mhz actually, for 100nS periods. 100nS is 1/10 of a microsecond. But I'm not transmitting 10Mhz. I think 1.5M...
