不同分词器在elastic中的实际效果

介绍不同分词器的文章不少，较经典的有BosonNLP 11款开放中文分词引擎大比拼

可惜这11款分词器只有IK和结巴一直在更新elastic的分词器插件，Boson的插件已经很久没更新

所以加上elastic自带的smartcn 也就只有三种分词器可选。

First, install arch-install-scripts:

sudo pacman -S --needed arch-install-scripts

Secondly, mount your partitions in all the internal hard drives.

Thirdly, generate and validate your config by piping it out to stdout:

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore. The list of supporting software reflects the known state as of this date. ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

Ctrl + Alt + Space

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
