percol とは

percol は入力の1行を1候補として,部分一致かつ AND 検索で絞り込みし,選択した候補を出力するコマンドです.端的に言えば Emacs の anything.el のコマンド版です.

How to diff PDF files with Git

One can use MD5 or plain text diff to see differences in PDF files. If that's not enough, here's how to use diff-pdf which knows how to diff based on appearance or words:

  • brew install diff-pdf
  • edit your ~/.gitconfig to add this:
[difftool "diffpdf"]
  cmd = diff-pdf --view \"$LOCAL\" \"$REMOTE\"

kafka introduction

Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

  • Producers send messages to brokers
  • Consumers read messages from brokers
  • Messages are sent to a topic

tungel / my Arch Linux cheat-sheet
Created July 8, 2013 13:42
I have kind of short term memory so I like to take note of what I've done. This cheat-sheet log some of the things I've done to my Arch Linux machine. Lots of these stuffs are based on my personal preference and may not be applicable to you. Also take note that: I'm not responsible if you break your machine by following any of the steps in this …
Installing Arch:
sudo vim /etc/pacman.conf
Update packages list: sudo pacman -Syy
run sudo pacman -Syu before installing any software (to update the repositories first)
* Timing issue:
- Change hardware clock to use UTC time:
sudo timedatectl set-local-rtc 0
