| What I want to know: | |
| ---- What's interest that I have to pay at payment N ? | |
| ---- What's principal that I have to pay at payment N ? |
I have a fast producer (client) and slow subscriber (server) due to slow Internet connection. How to decouple the connection such that server won't affect client performance?
In order to avoid drag down client IO, e.g. waiting for ACK from server, there are a few solutions:
/etc/passwd filetail -n +11 /etc/passwd| sort -t$':' -k3 -n | awk -F":" \
'
BEGIN {
printf "GID | Name | User_dir | Bash_Access | Description \n"
printf "--- | ----------- | ----------------- | ------------------ | -----------------\n"
}
{
printf "%s | %s | %s | %s | %s\n",$3, $1, $6, $7, $5 | bqkrtxgkmriwsiwcngtivpx.info | |

| # Enable fractional scaling on Ubuntu 18.04 | |
| # | |
| # Problem: | |
| # -------- | |
| # - Ubuntu 18.04 runs on Gnome 3.28, whichs does not support fractional scaling (120%, 130%). | |
| # - As a result, the text and icon on my 4K 27" monitor are very small. | |
| # | |
| # Usage: | |
| # ------- |
| // Async should be first priority over callbacks and promises | |
| // | |
| // High level idea: | |
| // - Avoid .then .catch in promise | |
| // - Syntatic sugar to make async programming similar to sequential code | |
| const axios = require('axios'); | |
| DEFAULT_URL = "https://jsonplaceholder.typicode.com" | |
| async function getUser(id) { | |
| let resp = await axios.get(`${DEFAULT_URL}/users/${id}`) |
Built-in Clang / LLVM shipped by Xcode does not support Leak Santizer (-fsantize=leak) feature. For example, this code has memory leak:
// File: main.c
