This doesn't do a hole lot. Ciro Santilli wouldn't really call it a web framework. It's more like a middleware. Real web frameworks are built on top of it.
Examples under: nodejs/express:
- nodejs/express/min.js: minimal example. Visit localhost:3000 and it shows
hello world. It is a bit wrong because the headers say HTML but we return plaintext. - nodejs/express/index.js: example dump with automated tests where possible. The automated tests are run at startup after the server launches. Then the server keeps running so you can interact with it.
A live example on Heroku can be seen at: github.com/cirosantilli/heroku-node-min

The physics not as good as the original Mario Kart 64, and it is notably missing jump gliding, and generally not as sharp! But it is really not bad.
Some of the weapons were too useless that you are just better firing them straight away at wall immediately to get something better, they could have a little better balancing there. I'm talking about you gatling that takes 10 seconds to finish firing, and does not kill enemies immediately. You are better off just firing that gun immediately when you get it to be able to get another gun ASAP. They seem to have done some balancing there however.
It had no chat option, but in a way it was cool to be forced to communicate non-verbally with people whose usernames you got familiar with. Funny you can love people like that, without ever talking to them. The best way of doing so being tea-bagging by going back and forth on a player after winning.
Performance was sometimes a problem. When Ciro tried it again on December 2022, it was unplayable due to the impossibly large lag. Tiings were much better again in 2023 however it seems.
www.newyorker.com/magazine/2022/03/07/a-journey-to-the-center-of-our-cells A Journey to the Center of Our Cells (2022) by James Somers comments on M. genitalium in general, and in particular on the JCVI strains.
The process that imports proteins encoded in the nuclear DNA and made in the cytosol into the mitochondria.
The term is mentioned e.g. in this article: www.nature.com/articles/nrm2959.
Power, Sex, Suicide by Nick Lane (2006) suggests that proteins are somehow tagged with extra amino acids for this.
Big companies manage to publish white papers in peer reviewed journals by Ciro Santilli 34 Updated 2024-12-15 +Created 1970-01-01
Ciro Santilli 34 Updated 2024-12-15 +Created 1970-01-01Big companies like Google are able to publish white papers as peer reviewed papers just due to their reputation, e.g. without giving any source code that is central for the article.
It is insane.
E.g.: AlphaGo is closed source but published as www.nature.com/articles/natnure16961 in 2016 on Nature.
Not the same as Hermite polynomials.
Boring rule that says that less energetic atomic orbitals are filled first.
Much more interesting is actually determining that order, which the Madelung energy ordering rule is a reasonable approximation to.
The cheapest and most resilient way to publish text content humanity has achieved so far.
Some tests:
- github.com/cirosantilli/jekyll-cheat: cirosantilli.com/jekyll-cheat
- Test with a
.nojekyllfile. - github.com/cirosantilli/test-gh-pages-min: cirosantilli.com/test-gh-pages-min. Minimal version of the above.

Ciro Santilli 34 Updated 2024-12-15 +Created 1970-01-01Section type:
sh_type == SHT_RELA.Common name: "relocation section".
.rela.text holds relocation data which says how the address should be modified when the final executable is linked. This points to bytes of the text area that must be modified when linking happens to point to the correct memory locations.Basically, it translates the object text containing the placeholder 0x0 address:to the actual executable code containing the final 0x6000d8:
a: 48 be 00 00 00 00 00 movabs $0x0,%rsi
11: 00 00 004000ba: 48 be d8 00 60 00 00 movabs $0x6000d8,%rsi
4000c1: 00 00 00It was pointed to by
sh_info = 6 of the .symtab section.readelf -r hello_world.o outputs:Relocation section '.rela.text' at offset 0x3b0 contains 1 entries:
Offset Info Type Sym. Value Sym. Name + Addend
00000000000c 000200000001 R_X86_64_64 0000000000000000 .data + 0The section does not exist in the executable.
The actual bytes are:
00000370 0c 00 00 00 00 00 00 00 01 00 00 00 02 00 00 00 |................|
00000380 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|The
struct represented is:typedef struct {
Elf64_Addr r_offset;
Elf64_Xword r_info;
Elf64_Sxword r_addend;
} Elf64_Rela;So:
- 370 0:
r_offset= 0xC: address into the.textwhose address this relocation will modify - 370 8:
r_info= 0x200000001. Contains 2 fields:ELF64_R_TYPE= 0x1: meaning depends on the exact architecture.ELF64_R_SYM= 0x2: index of the section to which the address points, so.datawhich is at index 2.
The AMD64 ABI says that type1is calledR_X86_64_64and that it represents the operationS + Awhere:S: the value of the symbol on the object file, here0because we point to the00 00 00 00 00 00 00 00ofmovabs $0x0,%rsiA: the addend, present in fieldr_added
This address is added to the section on which the relocation operates.This relocation operation acts on a total 8 bytes. - 380 0:
r_addend= 0
So in our example we conclude that the new address will be:
S + A = .data + 0, and thus the first thing in the data section.- Compiler toolchains generate and read ELF files.Sane compilers should use a separate standalone library to do the dirty work. E.g., Binutils uses BFD (in-tree and canonical source).
- Operating systems read and run ELF files.Kernels cannot link to a library nor use the C stlib, so they are more likely to implement it themselves.This is the case of the Linux kernel 4.2 which implements it in th file
fs/binfmt_elf.c.
