\varphi is the one that actually looks like the default standard modern lowercase phi, while \phi is the weird one. I love life.Real hardware is for newbs. Real hardware is for newbs.
Tested on Ubuntu 23.10 we approximately follow instructions from: docs.zephyrproject.org/3.4.0/develop/getting_started/index.html stopping before the "Flash the sample" section, as we don't flash QEMU. We just run it.

./setup.shThe installation procedure install all compiler toolchains for us, so we can then basically compile for any target. It also fetches the latest Git source code of Zephyr under:
~/zephyrproject/zephyrThe "most default" blinky hello world example which blinks an LED is a bit useless for us because QEMU doesn't have LEDs, so instead we are going to use one of the UART examples which will print characters we can see on QEMU stdout.
Let's start with the hello world example on an x86 target:and it outputs:The
cd ~/zephyrproject/zephyr
west build -b qemu_x86 samples/hello_world -t runHello World! qemu_x86qemu_x64 on the output comes from the CONFIG_BOARD macro github.com/zephyrproject-rtos/zephyr/blob/c15ff103001899ba0321b2c38013d1008584edc0/samples/hello_world/src/main.c#L11#include <zephyr/kernel.h>
int main(void)
{
printk("Hello World! %s\n", CONFIG_BOARD);
return 0;
}The
qemu_x86 board is documented at: docs.zephyrproject.org/3.4.0/boards/x86/qemu_x86/doc/index.htmlYou can also first
cd into the directory that you want to build in to avoid typing samples/hello_world all the time:cd ~/zephyrproject/zephyr/samples/hello_world
zephyr west build -b qemu_x86 -t runYou can also build and run separately with:
west build -b qemu_x86
west build -t runAnother important option is:But note that it does not modify your
west build -t menuconfigprj.conf automatically for you.Let's try on another target:and same output, but on a completely different board! The
rm -rf build
zephyr west build -b qemu_cortex_a53 -t runqemu_cortex_a53 board is documented at: docs.zephyrproject.org/3.4.0/boards/arm64/qemu_cortex_a53/doc/index.htmlThe list of all examples can be seen under:which for example contains:
ls ~/zephyrproject/zephyr/sampleszephyrproject/zephyr/samples/hello_worldSo run another sample simply select it, e.g. to run
zephyrproject/zephyr/samples/synchronization:west build -b qemu_cortex_a53 samples/synchronization -t runBasically a synonym for doing a large chunk of de novo DNA synthesis.
Ciro Santilli publishes videos of this not-so-common visual programming experiments on his YouTube channel occasionally: www.youtube.com/c/CiroSantilli. Ciro should however not be lazy and also upload each video produced to Wikimedia Commons, since YouTube does not offer a download option even for videos marked with a Creative Commons license: www.quora.com/Can-I-download-Creative-Commons-licensed-YouTube-videos-to-edit-them-and-use-them/answer/Tarmo-Toikkanen!
This is also where Ciro's downtime converged to in his early 30's, since he long lost patience for stupid video games and television series.
Ciro developed one interesting technique: while scrolling through YouTube's useless recommendations, when he understands what a channel is about, he either immediately:This helps to keep this feed clean of boring stuff he already knows about. There is unfortunately an infinite amount of useless videos out there however on the topics of:and no matter how much you say you don't want to hear about them, YouTube juts keeps on sending more.
- subscribes if it is amazing and then "Don't recommend channel"
- otherwise just "Don't recommend channel" immediately
- sports
- music, mostly idiotic top of the charts
- news and political commentary
- food
- programming tutorials. Meh, got Stack Overflow.
- stuff that is not in English, and notably languages that Ciro does not even speak!
- motorcycles
- ASMR
- cute animals
- gaming and movie commentary. Ciro is interested only in a very specific number of video games
- nature life, e.g. hiking, cycling, or living in isolation, this Ciro enjoys
- science for kids (popular science)
Things Ciro hates about YouTube:
- you can't follow or ignore a subject, only indirectly tell the algorithm about that. Once you click a popular cat video, you will be forced to watch cat videos for all eternity.
Likely FFmpeg is the backend of YouTube.

ASCII art of a Force of Will, a famous and powerful Magic: The Gathering card first printed in 1996.
This is Ciro Santilli's personal favorite ASCII art he has found in the blockchain so far. Also Ciro could not find any other previous source of this, so there is some chance it is original. One can dream.
The choice of card is probably linked to the function of the card in the game of Magic: The Gathering. This card essentially prevents the opponent from casting a spell they are about to cast. The presumed intended meaning of this art is further accentuated by the old card type term "interrupt" (late renamed to "instant"), which suggests that "this ASCII art is an interruption to the normal monetary transactions of the blockchain".
One of also reminded of the prayer wars interruption attempts. We could not however identify anything specific that this ASCII art might have tried to interrupt besides the normal flow of monetary transactions.
If one goes full art critic mode, it is also tempting to draw a parallel between the card's "You may pay 1 life" alternative casting cost (as opposed to 5 mana, 3 and two blue, which is a very large cost for most games) as being a reference to the money spent by the uploader of the art to upload it.
TODO understand exactly how it was encoded and why it is so weird. The
UUUU has a slightly weird encoding which we fixed by hand here TODO understand. -------------------------------------

Erich,
Bro, this looks excellent!!
