Use one of these techniques to install node and npm without having to sudo. Discussed in more detail at http://joyeur.com/2010/12/10/installing-node-and-npm/ Note: npm >=0.3 is *safer* when using sudo.
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl https://www.npmjs.org/install.sh | sh

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]

何故私は Heroku から離れたか、および新しい AWS セットアップのメモ

原著者:Adrian Holovaty
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。

NGINX tuning for best performance

Moved to git repository: https://github.com/denji/nginx-tuning

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.

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。
