// as Safari 6 doesn't have support for NavigationTiming, we use a Date.now() timestamp for relative values

// if you want values similar to what you'd get with real perf.now, place this towards the head of the page
// but in reality, you're just getting the delta between now() calls, so it's not terribly important where it's placed

To limit a CPU to a certain C-state, you can pass the processor.max_cstate=X option in the kernel line of /boot/grub/grub.conf.

Here we limit the system to only C-State 1:

    kernel /vmlinuz-2.6.18-371.1.2.el5 ... processor.max_cstate=1

On some systems, the kernel can override the BIOS setting, and the parameter intel_idle.max_cstate=0 may be required to ensure sleep states are not entered:

Noto Sans JP

Noto Sans JPをWebサイトで使う場合、大きく分けて2つの方法があります。

1. CDNを使う場合
2. サーバーにフォントファイルを置く場合

CDNの場合は、他のサイトを含めて一度でも読み込まれていればブラウザ側でキャッシュを持っているので、読み込み速度が速くなることが期待できます。
サーバーのフォントファイルはサブセット化（不要なデータを削除すること）でファイルサイズを削減できるメリットがあります。

基本的にはCDNを利用して、フォールバックとしてサーバーに置いたフォントファイルとシステムフォントを指定するのがいいでしょう。

Random "Freezing" with AMD Ryzen CPUs

It seems that numerous GNU/Linux users (including myself) have been having issues with the system randomly "freezing" during light usage. From journalctl output and anecdotal accounts, it is speculated that the AMD Ryzen CPUs do not support other C-states for power management very well (at least on GNU/Linux distributions), and the freezing may be resolved by limiting the C-state of the CPU.

Possible Solution

Limiting the C-state of the CPU can be done through the addition of the following kernel boot parameter.

processor.max_cstate=1

Tips for Ubuntu 64bit on Raspberry Pi 4.md

Introduction

The purpose of this gist is to give to tips for using Ubuntu 20.04 () 64bit on Raspberry Pi 4.

Hardware Accelerated OpenGL (Broadcom V3D)

As of today (July 22nd 2020), the latest kernel available in Focal apt is 5.4.0-1013. Unfortunately, that kernel lacks a clock required by the v3d module.
