www.youtube.com/watch?v=v7iAqcFCTQQ shows their base technology:
- laser beam comes in
- input set via of optical ring resonators that form a squeezed state of light. Does not seem to rely on single photon production and detection experiments?
This is where "fun" stuff is likely to be.
The idea is cool. It really unifies front-and back end.
But Ciro Santilli feels the approach proposed by FeathersJS of being a glue between bigger third-party Front-end web frameworks like React and backend (object-relational mapping) is more promising and flexible.

Ciro Santilli once talked to a man who had been working on high-frequency trading for the last six years.
He was quite nice.
Ciro asked him in what way did he feel his job contributed to the benefit of society.
He replied that it didn't contribute at all. It was completely useless. More than that, it so completely useless, that it was even pure. A bit like advanced mathematics, but not even providing beauty for anybody outside of the company, since everything is a closely guarded trade secret, unlike mathematics which is normally published for the vanity recognition.
And so, Ciro was enlightened.
Sections with
sh_type == SHT_STRTAB are called string tables.They hold a null separated array of strings.
Such sections are used by other sections when string names are to be used. The using section says:
- which string table they are using
- what is the index on the target string table where the string starts
So for example, we could have a string table containing:
Data: \0 a b c \0 d e f \0
Index: 0 1 2 3 4 5 6 7 8And if another section wants to use the string
d e f, they have to point to index 5 of this section (letter d).Notable string table sections:
.shstrtab.strtab
Holds strings for the symbol table.
This section has
sh_type == SHT_STRTAB.It is pointed to by outputs:
sh_link == 5 of the .symtab section.readelf -x .strtab hello_world.oHex dump of section '.strtab':
0x00000000 0068656c 6c6f5f77 6f726c64 2e61736d .hello_world.asm

Spin like mad between:
- standards
- high level generators. We use the assembler
asand linkerld. - hexdumps
- file decompilers. We use
readelf. It makes it faster to read the ELF file by turning it into human readable output. But you must have seen one byte-by-byte example first, and think howreadelfoutput maps to the standard. - low-level generators: stand-alone libraries that let you control every field of the ELF files you generated. github.com/BR903/ELFkickers, github.com/sqall01/ZwoELF and many more on GitHub.

execsystem call of the Linux kernel can parse ELF files to starts processes: github.com/torvalds/linux/blob/v4.11/fs/binfmt_elf.c, stackoverflow.com/questions/8352535/how-does-kernel-get-an-executable-binary-file-running-under-linux/31394861#31394861
