Cloud Miniconf

• <1> ​Deltacloud: abstracting for freedom - David Jorm and Stephen Gordon
  • ​比較 libvirt, OpenStack, deltaCloud, libcloud, opennebula 的 Google Trends 可以大致上發現 libvirt 、OpenStack 與 OpenNebula 被搜尋的機率還是比較高。
  • 
  • ​Cloud computing technologies overview and comparison - 這篇列舉了現有的雲端技術
  • ​Cloud Service Management 這篇文章則從 IaaS, PaaS 的角度切入，顯示不同雲端技術的定位
  • ​Coalitions and Communities - 3 Cloud Initiatives from the Summer of 2010
  • ​Comparing open source cloud platforms: OpenStack versus Eucalyptus - 比較 OpenStack 與 Eucalyptus
  • 
  • deltaCloud
    • ​http://incubator.apache.org/deltacloud/
  • libvirt
    • ​http://libvirt.org/
  • OpenStack
    • ​http://www.openstack.org/
    • OpenStack 是一個美國太空總署和 RackSpace 合作研發的雲端運算‎軟件，以 Apache 許可證授權，並且是一個自由軟件和開放原始碼項目。
• <2> ​Cloud computing: finding the silver lining for government - Pia Waugh

Arduino Miniconf

• <1> High Altitude Arduino: Horus by Joel Stanley and Mark Jessop
  • 很好玩的一個專案，用 Arduino 做高空氣球的資料量測。展示影片很好玩，把企鵝玩偶跟著高空氣球丟到接近外太空～
  • ​http://projecthorus.org/
• <2> Shield Design: Do It Right! - by Jonathan Oxer
  • 分享一些 Arduino 實驗板 Layout (PCB) 的經驗，例如在洗板子之前，先印出 1:1 的 Layout 並且檢查每個元件可以正確擺上去。
  • ​http://www.freetronics.com/
  • ​http://www.practicalarduino.com

• <3> Network of Things - Andy Gelme
  • Networking - WAN, LAN, PAN
  • 硬體：改裝 ASUS WL-500gP v2 無線基地台，加上 Arduino 當作 LCD 操作介面
  • 軟體：Linux, OpenWRT
  • 語言：Lua ( ​http://lua.org ) 因為已經有裝了
  • 因為 ASUS 停產硬體了，所以只好自己製作 Arduino 版本 Dragino Router
  • CPU Atheros AR2317
  • ​http://dragino.com , ​http://geekscape.org , ​http://www.flukso.net
• <4> Arduino in Security - by Philip J Lindsay
  • ​http://www.sparkfun.com
  • 既然 Arduino 會連在網路上，也一樣需要資訊安全的保護。
  • New Arduino UNO 加入 Real USB 而不是軟體模擬，多了一塊 WiFi 的板子（WiFly Shield）、GPS Shield、MicroSD Shield
  • WiFly wrapper library
  • ​https://github.com/sparkfun/WiFly-Shield
  • 把所有新軟體加一加，變成 Open Layers 函式庫，可以用 Arduino 結合 Open Street Map 提供定位服務
  • Make Something! Document it too!
