riscv/timer.S Updated 2025-07-16
Tested on Ubuntu 23.10:
sudo apt install binutils-riscv64-unknown-elf qemu-system-misc gdb-multiarch
cd riscv
make
Then on shell 1:
qemu-system-riscv64 -machine virt -cpu rv64 -smp 1 -s -S -nographic -bios none -kernel timer.elf
and on shell 2:
gdb-multiarch timer.elf -nh -ex "target remote :1234" -ex 'display /i $pc' -ex 'break *mtrap' -ex 'display *0x2004000' -ex 'display *0x200BFF8'
GDB should break infinitel many times on mtrap as interrupts happen.
This is a quick overiew of ASCII art ordinal inscriptions.
It was obtained by casually scrolling down the list of the largest text ordinal inscription on less until patience ran out.
Some of them are dedicated ASCII art inscriptions, others are just small highlights to other more important text like code.
Although tere is some element of commercialism in some those inscriptions, a bit like what is rampant in the images, some of them are honestly just cool and possibly novel.
Ordinal ruleset inscription collections:
  • Humongous surfers. These are very large ASCII arts, by far the largest on the chain. Being so large allows for shades of gray to be encoded on the average luminosith of individual letters:
  • Michael Jackson Unicode art. Uses Unicode Braille characters. Marked "First Onchain Collection" and "Legends @ BTC" . Pretty cool design, the textures are quite cool and suggest glittering flying seat. Though if those ever sell, someone is going to get sued to Hell by MJ's estate!

tcpdump Updated 2025-07-16
To test it, let's get two computers on the same local area network, e.g. connected to Wi-Fi on the same home modem router.
On computer A, run on terminal 1:
sudo tcpdump ip src 192.168.1.102 or dst 192.168.1.102
Then on terminal 2 make a test request:
curl 192.168.1.102:8000
Output on terminal 1:

Formal proof is useless Updated 2025-07-16
The only cases where formal proof of theorems seem to have had actual mathematical value is for theorems that require checking a very large number of case, so much so that no human can be fully certain that no mistakes were made. Some examples:
SPARQL tutorial Updated 2025-07-16
In this tutorial, we will use the Jena SPARQL hello world as a starting point. Tested on Apache Jena 4.10.0.
Basic query on rdf/vcard.ttl RDF Turtle data to find the person with full name "John Smith":
sparql --data=rdf/vcard.ttl --query=<( printf '%s\n' 'SELECT ?x WHERE { ?x <http://www.w3.org/2001/vcard-rdf/3.0#FN> "John Smith" }')
Output:
---------------------------------
| x                             |
=================================
| <http://somewhere/JohnSmith/> |
---------------------------------
To avoid writing http://www.w3.org/2001/vcard-rdf/3.0# a billion times as queries grow larger, we can use the PREFIX syntax:
sparql --data=rdf/vcard.ttl --query=<( printf '%s\n' '
PREFIX vc: <http://www.w3.org/2001/vcard-rdf/3.0#>
SELECT ?x
WHERE { ?x vc:FN "John Smith" }
')
Output:
---------------------------------
| x                             |
=================================
| <http://somewhere/JohnSmith/> |

Crystal radio Updated 2025-07-16
This was the first generation of commercially successful radios.
It uses a crystal detector as its diode, which is a crucial element of the radio, thus its name.
They were superseded by transistor radios, which were much more reliable, portable and could amplify the signal received.
