He found that the more HTTP client requests he did, the more memory his Node process would consume, but it was really slow.
[...] Then I ran Node with UMEM_DEBUG set to record various important information about the memory allocations
[...] Every hour, it grabbed the output of pmap -x and a core file and stored those in Joyent Manta
[...] In MDB there's a particularly helpful command ::findleaks that will show you the memory addresses and the stack traces for leaked memory, not unlike using valgrind, but without all the performance penalty.
[...] At this point we knew that we were looking for something in v0.10 that called MakeCallback but that didn't first have a HandleScope on the stack. I then worked up this simple DTrace script.
TL;DR: There are three options to fix an NPM dependency:
- Open a bug ticket on the repository of the maintainer
- Fork & Fix
- Create a patch and fix it
J'avais tendance à privilégier la 2e solution, mais elle a l’inconvénient de créer une dépendance à github.com au moment du build, ce qui n'est pas toujours pratique dans un contexte d'entreprise... patch-package peut donc s'avérer bien pratique dans ce cas

Useful CLI when you have the RCON password of a Quake 3 server !
I have set up the script below as a cron job to alert me whenever a player connect to my friend server :
#!/bin/bash
set -o pipefail -o errexit -o nounset
cd $(dirname "${BASH_SOURCE[0]}")
date
echo status | quake3-rcon $server_address $rcon_password > quake3-kleph.status
grep -E '[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+' quake3-kleph.status | awk '{ print $4 }' > quake3-kleph.players
if ! diff -q quake3-kleph.players quake3-kleph.players.old; then
echo 'New player detected'
./send_reminder.sh "New player joined kleph.eu Quake3 server: $(comm -13 <(sort quake3-kleph.players.old) <(sort quake3-kleph.players) | tr '\n' ' ')"

If you want to share a best practice, or think one of these guidelines should be removed, feel free to share it with us.
