“If” – by Rudyard Kipling

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you,
But make allowance for their doubting too;
If you can wait and not be tired by waiting,
Or being lied about, don’t deal in lies,
Or being hated, don’t give way to hating,
And yet don’t look too good, nor talk too wise:

If you can dream – and not make dreams your master;
If you can think – and not make thoughts your aim;
If you can meet with Triumph and Disaster
And treat those two impostors just the same;
If you can bear to hear the truth you’ve spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
And stoop and build ‘em up with worn-out tools:

If you can make one heap of all your winnings
And risk it on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breathe a word about your loss;
If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: ‘Hold on!’

If you can talk with crowds and keep your virtue,
‘ Or walk with Kings – nor lose the common touch,
if neither foes nor loving friends can hurt you,
If all men count with you, but none too much;
If you can fill the unforgiving minute
With sixty seconds’ worth of distance run,
Yours is the Earth and everything that’s in it,
And – which is more – you’ll be a Man, my son!

— Rudyard Kipling, “If”, 1895

Serveur dédié : mettre à jour Apache pour HTTP/2

7 March 202420 décembre 2015 by Matt Biscay · Lecture: 6 minutes

C’est sur toutes les lèvres : 2015 aura vu l’arrivée de PHP7 et de la révision du protocole HTTP qui passe à la version 2, en remplacement du mod_spdy de Google.

Tout cela promet pas mal de gains de performance donc il est très tentant de le vérifier par nous-mêmes.

HTTP/2 : une évolution du protocole HTTP

Avec HTTP/1.1, la vie des développeurs n’était pas simple. L’optimisation d’un site revenait à plusieurs techniques qui tournaient toutes autour de l’idée de minimiser le nombre de requêtes HTTP vers un serveur d’origine.

Un navigateur ne peut ouvrir qu’un nombre limité de connexions TCP simultanées vers une origine et le chargement des ces ressources via chacune de ces connexions est un processus en série : la réponse de chaque ressource doit être retournée avant que la réponse de la ressource suivante ne soit envoyée. C’est ce qu’on appelle le head-of-line blocking.

HTTP/2 promet donc des gains de performance d’environ 30%, sans avoir à gérer ni minification ni concaténation dans le processus de création et déploiement des pages.

Plus besoin (normalement!) d’optimiser les connexions TCP ou les requêtes HTTP avec la création de sprites, le chargement des ressources directement dans le corps des pages, la concaténation ou la création de sous-domaines pour charger les ressources en parallèle (domain sharding) pour contourner les limitations d’HTTP 1.1.
