Terminal/Console flow control demo | |
Most terminals support ctrl+S/ctrl-Q for pausing and unpausing | |
writing to it, which can be useful in some situations. | |
However, note that the terminal pause does _not_ pause the whole process, | |
how terminal job control (ctrl-z) does. Instead, only the thread that | |
attempts to write to stdout will block, while other threads are free to | |
continue processing. Only way other threads would block is they, too, |

nanobind
is a tool and a library for implementing native C/C++ extensions for python.
You can implement such extensions in many ways, but nanobind
makes life a bit more
easier, especially if you write C++ and use CMake to build your native code.
nanobind
recommends using the scikit-build-core
as the build backend; it handles the
heavy lifting of building stuff through CMake during python package build process. It even
supports using Ninja. And as a cherry on top, it is able to download CMake and Ninja
from pypi
if they are not available locally.
// build and run with: | |
// $ gcc nullptr-shenanigans.c -Wall -Wextra -pedantic -std=c99 -O0 -o lol | |
// $ ./lol | |
// expected output: | |
// Got SIGSEGV at address: 0x0 (REG_RIP = 93937079497465) | |
// This should not print: p = (nil)? | |
// Allright then, we are done! | |
#define _GNU_SOURCE 1 /* To pick up REG_RIP */ |
2024-05-06: I was using telegram to send a message in one of the group chats I'm in.
2024-05-07: I noticed that a copy of my sent message was left as draft in the same chat (which is indicated by a red Draft:
prefix in the chat list). If I opened the chat group, the draft message would indeed be entered in the message
preparation box.
However, I could not erase the draft message; if I tried, it would simply return in a few seconds. I tried several times.
I noticed I could erase parts of the draft or add more. All those changes would be reflected between my phone and laptop.
