crates.io celebrates its 10 year anniversary today! 🎉

On 2014-06-25 Alex Crichton created the initial commit in the crates.io git repository: https://github.com/rust-lang/crates.io/commit/54cfc8d

A lot has happened since then, and the current crates.io team would like to say "thank you!" to all current and former contributors to crates.io and the ecosystem around it! 🤗

#rustlang

my first ever pull request for #nnn: https://github.com/jarun/nnn/pull/1904

If #Radare2 vs #Rizin makes no sense to you, perhaps #Python will. It is pretty solid tool for driving #Capstone :-)

Transcript:

raw = open('/home/jarkko/work/nnn/nnn', 'rb')
from elftools.elf.elffile import ELFFile
elf = ELFFile(raw)
symtab = {s.name: s for s in (elf.get_section_by_name('.symtab')).iter_symbols()}
sym = symtab.get('move_cursor')
addr = sym['st_value']
size = sym['st_size']
text = elf.get_section_by_name('.text')
offset = addr - text['sh_addr'] + text['sh_offset']
raw.seek(offset)
payload = raw.read(size)
from capstone import Cs, CS_ARCH_ARM64, CS_MODE_ARM)
disasm =  Cs(CS_ARCH_ARM64, CS_MODE_ARM)
for opcode in disasm.disasm(payload, addr):
    print(f"0x{opcode.address:x}:\t{opcode.mnemonic}\t{opcode.op_str}")

Just got a bit familiar this. The main benefits are obviously:

• Recursive traversal #disassembly (vs linear sweep style in objdump)
• Re-usable analysis
• No boundaries how you can post-process the analysis (or visualize it)

I find this super fascinating!

The SIGPLAN Programming Languages Software Award goes to the original Rust team!!!!!

After reading #Ueber’s post about their use of #Zig, I tried it to random C and C++ projects:

export CC="zig cc"
export CXX="zig c++"
make

At least for relatively small projects such as nnn this seems to result working results. Still quite impressive. Next iteration would to replace Makefile with build.rs.

Also one tool that I like, ncdu, has successfully executed such conversion: https://dev.yorhel.nl/ncdu

I think I’ll try Linux with tinyconfig next by using this hacky script as basis next:

#!/usr/bin/env bash

set -e

make defconfig
scripts/config --set-str CONFIG_INITRAMFS_SOURCE "initramfs.txt"
yes '' | make oldconfig

cat > initramfs.txt << EOF

dir /proc 755 0 0

mkdir initramfs

curl -sSf https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/busybox-static-1.36.1-r25.apk | tar zx --strip-components 1
cp busybox.static initramfs/busybox

cat > initramfs/init.sh << EOF
#!/bin/sh
mount -t proc none /proc
mount -t sysfs none /sys

EOF

It is from my old’ish post: https://social.kernel.org/notice/AgzHqrYFGplZuYr3gG

PipeWire 1.2 Released With Async Processing, Explicit Sync & Other Features

PipeWire 1.2 was christened today as the latest major feature update to this solution common to the modern Linux desktop for managing audio/video streams...

another classic piece of software with *uncluttered* Tk GUI: #gitk :-) #git

#Python #IDLE is still rockin' :-) Always have it open as my calculator (and doing binary analysis and whatnot).

I don’t get the #xscreensaver dependency that #Signal has…

Way to get #ARM64 #RPM for #Signal: https://github.com/BarbossHack/Signal-Desktop-Fedora

And #widevine: https://github.com/AsahiLinux/widevine-installer

Just an observation but if considering testing ARM64-Linux, Apple is actually a “budget choice” compared to:

1. Low-volume Linux ARM64 laptops (few available).
2. ARM64 server racks.

Especially if you take -1 gen Apple hardware, which you can get for bargain prices pre/post the next WWDC ;-) The laptop seen in previous screenshot is M1 Pro, and it is quite nice and fast , and that is even -2 gen.

#note to myself, not throughly thought out...

Useful #kernel feature for #hibernate might be a file that would tell the number of pages required for hibernate.

The "O-figure" for hibernate is AFAIK O(n+sqrt(n)) but exact number is dependent on kernel internals but in theory could be calculated by simulating the process without committing.

Instead of swap it might also be useful to have "spare" volume of ~100 GB for doing hibernate and e2scrub type of operations, which could have its own design for encryption etc. Swap for swapping overcommitted memory more than few at most GiB is not that useful these days.

Just an observation, not a political opinion, but it might be that Mr Biden and Mr Trump are the oldest duel in any presidential election of any democratic country in the world ever in the history of mankind.

On the bright side, it means that US has no age racism I guess then 🤷

I feel like if you are going to take time to talk to Tucker Carlson, you deserve everything that's about to come to you.

I do, however, hope nothing happens to the users.

Telegram says it has 'about 30 engineers'; security experts say that's a red flag | TechCrunch

Despite being somewhat controversial figure, I really don't think that either of these would have been appropriate end outcomes for Mr Assange:

1. Guantanamo Bay
2. ADX Florence

This is not same as saying that I would fully support all the choices and values of the person in question.

I had my first ever Mandela Effect experience, I recall seeing reports of his death like half years ago.

Anyway, congrats to Mr Tanenbaum, well deserved! Only thing that surprises me is that why he did receive ACM award earlier than this.
