what program is used to create those graphs? i have used that script from explaining computers

LibreOffice Calc on the Pi 4 I find it quite usable.

From https://wiki.debian.org/Hugepages#Enabling_HugeTlbPage I think the default Raspbian kernel doesn't have it enabled: root@rpi4b:/home/pi# zcat /proc/config.gz | grep HUGEPAGE CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE=y # CONFIG_TRANSPARENT_HUGEPAGE is not set root@rpi4b:/home/pi# So you'd have to b...

Ok, but how well does the built-in WiFi and Bluetooth work in a metal enclosure? I haven't tested Bluetooth but Wifi seems to work fine from 1st floor to router on ground floor: With case: pi@raspberrypi:~/Downloads $ iperf -c 10.0.0.254 -p 4711 -t 60 -i 10 -----------------------------------------...

73'C sounds pretty close to 80C when i understand throttling will start. What happens after a few hours of watching hi-def video or browsing add and clickbait covered social media pages if its hitting 73c internally after only 1 hour or so?? Well, assuming idle temp of 41'C, 73'C is only at 82% of ...

Did you try out both HDMI ports? The one closets to the USB C port is the one that is used by default.

I've achieved pretty good temperatures ( I think) by using a couple of copper heatsinks inside one of the acrylic style cases available from Amazon. I decided the tiny noisy fan had to go, and so 3d printed a new lid for the pi which will accommodate a 40mm noctua 5v model. Temps running the same s...

I just received a flirc case. Ran the same test as the guy from Explainingcomputers : Ambient Temperature: 27.0'C temp=41.0'C temp=50.0'C temp=52.0'C temp=54.0'C temp=54.0'C temp=56.0'C temp=57.0'C temp=59.0'C The hottest spot on the case that I could find was 41'C. So this case not only looks beau...

You could have a look at http://www.raspberrypi.org/phpBB3/viewt ... 35&t=19799, though it might be overkill for what you want.

Have you tried to connect to the serial console (http://codeandlife.com/2012/07/01/raspberry-pi-serial-console-with-max3232cpe/) to see if there is any boot activity? Also, referring to http://elinux.org/R-Pi_Troubleshooting#Green_LED_blinks_in_a_specific_pattern you could try to remove e.g. loader....

The cmdline.txt file on the boot partition of the SD card points to the partition to be used as root file system. You might be able to put the debian rootfs in one partition, the openelec in another partition and create a script under both systems to choose which OS to boot at the next boot. The scr...
