NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Safari iframe cookie workaround

Safari by default discards cookies set in an iframe unless the host that's serving the iframe has set a cookie before, outside the iframe. Safari is the only browser that does this.

The 10k foot view

In order to get around the issue, the parent (src) and child/iframed/remote (dest) site have to work together, if the source site only wants users to access the destination via the iframe and can't assume that the user has visited the destination host before.

概要

Why Uber Engineering Switched from Postgres to MySQL - Uber Engineering Blog のまとめ

Posgresqlだと

pgは追記型なので少しの更新でも多くのdiskへのwriteがおきる
カラムを一つ更新しただけで多くのindexの書き換えが起こる
よって、replicationはWALを送るので更新が多いとWALが大量に送られる
repcliationでは物理的なdiskの変更を送る
DC間でレプリするときつい
bugがあってreplica間でMVCCの不整合が起きる

QdmailをPHP7.0に対応させる

コンストラクタ名を__constructorに修正
newの前の&を削除
QdmailComponent内のfunction & smtpObjectの引数をスーパークラスと合わせて$null = falseに修正

First Method

Deleting the .git folder may cause problems in our git repository. If we want to delete all of our commits history, but keep the code in its current state, try this:

# Check out to a temporary branch:
git checkout --orphan TEMP_BRANCH

# Add all the files:
git add -A

	<html>
	<!-- You may need to download them from https://github.com/brix/crypto-js/tree/release-3.1.2/build -->
	<script src="rollups/sha1.js"></script>
	<script src='components/lib-typedarrays-min.js'></script>
	<body>
	<script>
	function sha1sum() {
	var oFile = document.getElementById('uploadFile').files[0];
	var sha1 = CryptoJS.algo.SHA1.create();
	var read = 0;

	Replace with your own usename and email:
	------------------------------------------------
	git config --global user.name "Username"
	git config --global user.email "[email protected]"

	These next two commands tell Git to use your Windows credentials to store your origin password.

	git config --global credential.helper wincred
