The reason about this is introduction ZMQ to everyone

If you only have a hammer you tend to see every problem as a nail

zero as in none, nada, nil MQ as in Message Queue

with ZeroMQ, you can create brokerless mq with zeormq

FYI: Broker vs Brokerless

Supprots:

• inproc, IPC, TCP, pgm, epgm

MUTE strategy

2 kind of MUTE states: DROP , BLOCK

PUSH

In MUTE strategy, the producer doesn't care about reply.

PULL

• In incoming strategy
• fair-queue

PUB

• In OUTGOING strategy

  • fan-out

• MUTE

  • drop

SUB

• INCOMING strategy

  • fair-queue

• OUTGOING strategy

  • none

• MUTE strategy

  • none

Demo: Multi message handle worker

• Have a http server in front use express.
• Multiple handle for pull and pub message.
• Workers will try to reconnect the server if front server down.

Conclusion

• 0mq is a lightweight networking library.
• Build messaging topologies you want.
• Nice async features enabling you to do fun stuff (add/kill worker).
• Use to connect apps written in different languages/tech stacks.
• A very useful tool to have and understand.

R0 #4 - 打造前端團隊之路

吳亮 @75Team

• 2012 ~ 奇虎 360 奇舞團團長 (> 70 人)
• 支援的業務有搜尋、電商、APP、遊戲、行動 等等
• 成員分散在公司大樓各處

全局規劃

• 目標設定 1 學習, 工作 2 累積, 沈澱 3 分享 4 影響力

• 技能組成

  • 前端通用技能
  • ActionScript, PHP, Node and etc.

• 人員配置

  • 工程師
  • 業務接口人
  • 自由人, 團隊中技術較強的人, 不屬於任何一個 team, 負責前期 PoC

前後分離

技術能力

解決 high concurrency 的前端問題 技術債的問題解決 跨裝置的問題解決

高手也是會犯低級錯誤, e.g. 瀏覽器內核優化卻把 confirm 改成跟 alert 一樣 夜間模式的全域 css 與本來的樣式打架了 隨著瀏覽器 JS 的效能越來越強大, 前端工程師接觸到的內容也越來越不一樣 開始要考慮數學算法的最佳化 demo 會動的貓眼

選擇技術實踐時 會有很多理論 但是數據也很重要 靠數據來做最終抉擇

編譯部署

各種內部工具

R0 #5 - Node.js, p2p and MAD SCIENCE

Mathias Buus

@mafintosh

javascript bittorrent

Bittorrent is way more normal way to transmit data clients share data between each other instead.

many pieces hashes of the file

store hash files in one server, name torrent file

recursion

magnetlink = hash([
    hash(pieces),
    hash(pieces),
    hash(pieces)
  ]);

Distributed hash table

basiclly like normal table like sql

every peer joins the dht

{
  magnet_link_1: 'my-ip:my-port',
  magnet_link_2: 'my-ip:my-port'
  ...
}

How can we make bittorrent stream

concurrent fetch of most critical pieces

If some peer is bad peer, we still can get the critical piece from other peer.

torrent-stream

peerflix

streaming torrent and watch streaming video use vlc

Not a gimmick

MAD SCIENCE

Stream any content

peerwiki Browse all wikipedia use bittorrent

O_o linux is on bittorrent

What if virtual box -understood streams-?

torrent-mount

Mounts a torrent as a file system

abstract-blob-store

torrent-blob-store

instant.io

chrome-net Use Node net API in Chrome app (via Browserify).

R0 Last talk - GitHub 大冒險

Muan, Github

muan, @muanchiou

Co-founder of zeczec

Important things of remote work,

• Be asynchronous
• Be non-blocking

Cares about code

• Code Style guide

• Stale selectors and partials

These classes are no where to be found:

• Deep selectors

• Special prefixed classes

.js- prefix only use for js binding, it's can't be exist in stylesheet

Lint your code
