a simple guide for getting a local web server set up

Do I have a web server running?


having a web server turned on doesn't necessarily mean you are serving pages on the world wide web. its what allows you to load your own static files (.html, .js etc.) in a browser via http://.

if you're not sure whether or not you have a web server running, no problem! its easy to confirm.

what happens when you visit http://localhost/?

This Ruby script will bulk remove all Slack files older than 30 days. Just add your API token from https://api.slack.com/web#authentication into the token quotes at the top of the file.
require 'net/http'
require 'json'
require 'uri'
@token = ''
def list_files
ts_to = (Time.now - 30 * 24 * 60 * 60).to_i # 30 days ago

Gistの使い方のメモ

Gistの使い方のメモ

Gistを使い始めて気がついた点をメモした。 Gistはこのようなメモや短いコードをバージョン管理しながら公開するのに便利。

特にこのメモでは、画像を同一ディレクトリに置いて、 それGFMファイル内に挿入する方法を解説。

このメモにはgitコマンドの使い方の解説はない。 このメモは随時更新される予定。

NGINX tuning for best performance

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.

原文:Why I left Heroku, and notes on my new AWS setup

金曜日、私は Heroku から Amazon Web Services(AWS) を直接使うように Soundslice を移行しました。私はこの変更ができてとても、そうとても嬉しくて、私がどうやったかということと、もし皆さんが同じような立場だったら何故それを検討すべきかということについて広く伝えたいと思います。

How to permalink to a gist's raw file

Problem: When linking to the raw version of a gist, the link changes with each revision.

Solution:

To return the first file from a gist: https://gist.github.com/[gist_user]/[gist_id]/raw/

To get a file from multi–file gist: https://gist.github.com/[gist_user]/[gist_id]/raw/[file_name]
