The past, present and future of containers by Timothy Chen

The past, present and future of containers
圖片出處: https://denibertovic.com/talks/supercharge-development-env-using-docker/img/what_is_docker.png

這次的 docker talk 中, Tim 跟我們分享了整個 container 在 linux 中發展的概念。

因為一些技術問題,影片最後有點被切掉,但是還有錄到 90% 的分享。

Talk 簡介

You’ve heard the term “containers.” Maybe you’ve heard the buzz surrounding new technologies like Docker and CoreOS. They plaster the front pages of HackerNews and reddit .

If you’ve wondered just what the big deal is and what they are, this is a simple, what, why, and a how-to for containerization and how you can use it with your application.

Simply put, containerization enables you to scale your apps with increasing ease. For developers, you can abstract away your infrastructure and stop worrying about developing, testing, and running in identical environments – it’s all the same inside your container.

D3.js: the Core Concepts by Zero Cho

Special thanks to our sponsor:

Taulia drives innovation in the Financial Supply Chain. By turning every invoice into a revenue opportunity, Taulia enables organizations to strengthen supplier relationships while adding millions to the bottom line.

以前的記錄方式都是以聚會為單位,導致兩個以上不同 topic 的分享記錄有時候會寫在同一篇紀錄中,這樣對未來想要找資料的人來說,效果沒有很好。

因此,接下來的聚會記錄,會以 talk 為單位,把講師的錄影與提供的資料放在同一篇文章標題中,讓大家方便查詢。

首先,我們先來放 Zero 上上個月分享的 D3 吧!(太晚放是我的錯,Zero 不要打我~~~)

Talk 簡介

d3.js is a famous data visualization library. All the power of d3.js comes from its simplistic syntax and data binding. This talk will guide you through d3’s core concepts and its core function: data transformation. We will then use a network topology editor to showcase d3’s dynamic capability.

主題介紹

D3 早就已經是網頁資料視覺化的標準配備,幾年前還在前公司服務的時候, Sales Director 有天神秘兮兮地靠過來,喜孜孜地跟我們分享他在客戶那邊聽到的成功訣竅,就是公司產品做 charting 的時候可以使用 D3… XD

很可惜地,當初負責前端設計的工程師比較鍾意有商業支援的 highcharts ,錯失了實作 D3 的機會。

這次,爛熟 graph 的 Zero 繼上次聊完 routing 演算法後,這次跟我們分享 D3 的實作經驗,人真是太好了!

多謝工研院美西分院的贊助,這次 data science 的讀書肚 meetup 才能順利舉辦。

0 to Kaggle in 30 minutes

就算很多人聽過資料科學家的究極競技場 Kaggle ,也不一定人人都下場競技過,Ming Tsai 跟 You-Cyuan Jhang 這次的 talk 把資料科學的:

  • data preparation
  • training set/test set split
  • model training using just PostgreSQL, SQL, and Madlib
  • Kaggle result submission
  • … 等

的所有步驟清楚地介紹與 Demo,我想聽完這次 talk ,大家都可以下場玩玩。

Ming Tsai 與 You-Cyuan Jhang 目前在找挑戰 deep learning 的夥伴,請有興趣的一起加入打怪。

[聚會 #4 – 20 June @ 2pm] 0 to Kaggle in 30 minutes – by Ming Tsai and You-Cyuan Jhang

主題介紹

Kaggle 是資料科學家(data scientist)的終極競技場,每天都有世界上各地的資料科學家把自己精心準備的 model 送上來競賽,爭奪各地企業或研究機構所提供的題目與獎金。

如果我跟你說只要你會 SQL 語法,再加上一點點工具的幫助,30 分鐘內,你就能夠上場較勁,那該有多好?

期待 Ming 跟 You-Cyuan 把這入場卷教給我們。

聚會議程

2pm – 2:30pm: Introduction to Kaggle with SQL, using Hawq and Madlib.

[聚會 #3 – 記錄] Apache Mesos and Apache Spark – by Tim Chen and Chu-Cheng Hsieh

謝謝大家上禮拜六的參加,以下是上禮拜 meetup 紀錄。

Modern Techniques in Big Data Science

Chu-Cheng Hsieh 的 talk 是我看過把大資料分析(與工具)講得最淺顯易懂的,不僅輕鬆帶過 map/reduce/flat 等基礎的 map/reduce 概念,從過去的 hadoop,pig,到現在的 Spark,鉅細彌遺地講述了這些工具演化的歷史原因,還透露了他面試的問題以及回答的技巧(疑!?),請想要複習的朋友,服用以下的影片紀錄 + 投影片:

Introduction to Apache Mesos

如果你的 data center 的單位還是 VM ,你怎麼處理有些 VM 的 usage 只有 2% (只裝了一個測試用的 MySQL)的浪費?如果你的 data center 每季成長的幅度是 3 萬台,你怎麼設計這個複雜的管理系統,讓所有需要計算資源的工程師,都順利拿到資源?Mesos 就用 linux container 的方式刻出一個完美的 data center OS。

Note: Unplugged 以後,Tim 還分享了她如何從身為 Apache 專案 PMC 中,拿到很多創投贊助意願,以及 entrepreneur in residence 的機會。

[聚會 #3 – 16 May @ 2pm] Apache Mesos and Apache Spark – by Tim Chen and Chu-Cheng Hsieh

主題介紹

這個月是我們讀書肚的阿帕契(Apache)月,跟李蒨蓉沒有關係,是我們要介紹兩個最近紅透半邊天的 Apache Project:分散式/海量資料運算的 Apache Spark ,與 data center 專用的 Operation System,Apache Mesos

身為矽谷軟體工程師,談到 Big Data Analysis ,Machine Learning,或 Parallelism,你不能不知道當今 Yahoo,eBay,Neflix 爭相採用的 Apache Spark,談到 Data Center 的自動化或是 Resource Management ,你不能不知道現下 Airbnb,Twitter,Apple 趨之若鶩的 Apache Mesos

這次,讀書肚一次帶給你。

聚會議程

Apache Spark(2:15 pm to 2:45 pm)

Modern Techniques in Big Data Science

Apache Spark is becoming one of the most gossiping and the state-of-the-art framework to conduct data analysis on Hadoop platform. in this talk. I will discuss why PIG is fading out and why Java is not suitable for the big data analysis these days. Next, I will start with explaining the basic idea/motivation behind big data analysis (in my perspective), followed by explaining operations like “map, reduce, fold, join, etc.” and wrapped up with real world examples, including page rank calculation and clustering data sets.

Apache Mesos(2:45 pm to 3:15pm)

Introduction to Apache Mesos

Come learn how Apache Mesos, an open source distributed cluster
manager, can allow Twitter to have only three full-time SREs to manage
10s of thousands of nodes running in their datacenters and achieve
high utilization.
