Build LLVM / Clang on MacOS

Problem

Built-in Clang / LLVM shipped by Xcode does not support Leak Santizer (-fsantize=leak) feature. For example, this code has memory leak:

// File: main.c

#include <stdlib.h>

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

firefoxbookmarks() {
  mkdir -p /tmp/bookmark/ && \
  cp ~/.mozilla/firefox/0fkse04m.default/places.sqlite /tmp/bookmark && \
  sqlite3 -line /tmp/bookmark/places.sqlite 'select moz_places.url, moz_bookmarks.title from moz_bookmarks join moz_places on moz_bookmarks.fk = moz_places.id' && \
  rm /tmp/bookmark/places.sqlite

PythonでスタンドアロンのMac OS Xアプリケーションを作成する

Pythonのプログラムを配布可能なアプリケーションを作成する方法について扱います。

Pythonプログラムの実行方式

コンピュータが理解できるのは突き詰めると、0と1だけです。そのため、プログラムを実行するには「プログラミング言語で書かれたテキストのプログラム」を0と1に変換する必要があります。そのやり方には2つあり、ひとつはコンパイラを使うもので、もうひとつはインタプリタを使うものです。

以下に両者の違いについて記載します。
