計算 CPU utilization 於多核心的 ARM 系統 / CPU utilization on multi-core platform

目的: 計算 CPU utilization 於多核心的 ARM 系統

CPU info location:

1.          /proc/cpuinfo

2.          /proc/stat

3.          /proc/loadavg

4.          /proc/<pid>/stat

5.          /proc/<pid>/task/<tid>/stat

CPU test factor:

1.          CPU load

2.          CPU temperature

3.          Process CPU utilization

4.          Thread CPU utilization

5.          CPU frequency / scaling

6.          CPU BogoMIPS

7.          CPU benchmark

8.          CPU stress / long run

9.          CPU info

10.      Workload on specific CPU

11.      Power consumption

12.      Process queue

13.      Interrupt

14.      IO

15.      Context switch

Wubi.exe cannot install Ubuntu on Win7 32bit laptop

1.      Get Ubuntu 32bit ISO, extract wubi.exe from the ISO file.

2.      Put wubi.exe and ISO at the same folder.

3.      Run wubi.exe, and it will not download amd64 source file and install on 32bit from the ISO file.

4.      If Win7 use dynamic storage setting, then you cannot install Ubuntu by wubi.exe

Ubuntu 頻寬監控軟體 / Bandwidth monitoring tool

正在開發一些網路工具

剛好發現一個好用的 Linux 版本的頻寬監控軟體叫做 iptraf

可以針對某個 connection 進行監控，還會計算流量，很符合需求

其實國內的自由軟體協會與投身社群的菁英們，早就提出 WebOS 的概念並有實際的成果，就是 XPUD。但可惜的是，一直無法躍居國際市場，就連國內的 ODM 業者也只能依據客戶要求，選用特定的 OS，以致沒有任何實質的市場，殊為可惜啊。
