[歌詞翻譯] Deep Purple, Soilder of fortune

 

除了歌曲本身以外, 這首歌對我來說, 有特別的意義.

YouTube 的連結, 歌曲也很好聽, 不過不要在夜深人靜的時候聽, 那種悲傷的氛圍, 很凍.

歌詞原文

I have often told you stories about the way
I lived the life of a drifter waiting for the day
When I'd take your hand and sing you songs
Then maybe you would say
Come lay with me and love me
And I would surely stay
But I feel I'm growing older
And the songs that I have sung echo in the distance
Like the sound of a windmill going round
Guess I'll always be a soldier of fortune.
Many times I've been a traveler I looked for something new
In days of old when nights were cold I wandered without you
But those days I thought my eyes had seen you standing near
Though blindness is confusing it shows that you're not here.
Now I feel I'm going older
And the songs that I have sung echo in the distance
Like the sound of a windmill going round
Guess I'll always be a soldier of fortune
Yes, I can hear the sound of a windmill going round
I guess I'll always be a soldier of fortune.
I guess I'll always be a soldier of fortune.

 

歌詞翻譯

我常常跟你提起那一段我流浪著的故事, 直到那一天,我牽著你的手,為你唱歌. 也許你會說,留下來,愛我 。然後,我就會真的留下來。 但是,我感覺我正在老去, 而我唱過的歌,也只剩下遙遠的回音, 就像是迴盪在磨坊的低語, 我只能永遠當個傭兵戰士。

好幾次,我到處旅行,尋找新奇的事物。在古老的年代,冰冷的夜裡,我獨自漫遊。但是在那些日子裡,你的身影卻一直在我眼中,我盲目而且困惑,顯然你並不在這裡。現在,我覺得我正在老去,而我唱過的歌,也只剩下遙遠的回音, 就像是迴盪在磨坊的低語。我想,我會永遠是個傭兵戰士。

是的, 我仍然可以聽到磨坊的低語. 我想, 我只能永遠當個傭兵戰士。我想,我會永遠是個傭兵戰士。

 

註:

因為你沒有說 “留下來,愛我", 所以我沒有留下來, 我只能繼續為了別人的目標戰鬥的傭兵人生.

[i.MX6] Memos

 

About i.MX6

最近拿到一塊板子 Boundary Device 出的 Nitrogen6X, 雖然也買了一塊 mirco sd card, 很容易的就開機起來, 但是如果要自己做一些客製化的動作, 就不是那麼簡單. 怎麼做也許不是最困難的事, 要做什麼可能才是最難的. 怎麼說呢 ? 首先, 是要做一個 Ubuntu 的 embedded linux, 或是 Android 的 platform ? 因應需求的不同, 就會用到不同的 tool chain, build system, …. 然後就是一大堆的資訊, 最後就是被淹沒在這些東西當中.

載浮載沉幾次之後, 終於搞懂了一些東西. 也許了解得沒有那麼透徹, 如果有謬誤或更正請告訴我, 免得把錯誤的資訊傳染其他人, 那就不好了, 有建議也可以跟我說喔 : )

i.MX6 Family

iMX6 是 Freescale 出的一個處理器的系列. 我用到的是 i.MX6Q, 是四核心的版本, 有關 iMX6 的家族的資料, 可以參考以下連結 i.MX6 Family.

i.MX6 built images

一塊 SBC ( single board computer), 如果不能安裝作業系統, 那真的也是沒什麼用. 以下是已經 built 好的作業系統映像檔 (意思就是說, 這個板子可以跑這樣的作業系統). 我這邊的資料是來自 Boundary Devices, 因為板子是向他們買的 : ) 原始資料來源, 可以參考 Boundary Devices built images.

i.MX6 Toolchain

[i.MX6] Booting with image Ubuntu Trusty

 

這裡記錄 i.MX6 用預先 build 好的 image (Ubuntu Trusty for i.MX6 boards, June 2015 (kernel 3.10.53).

先在 http://boundarydevices.com/imx6-builds/ 這個網址, 找到 Debian/Ubuntu 的這一個類別, 再點選 Ubuntu Trusty for i.MX6 boards, June 2015 (kernel 3.10.53) 這個連結, 到 Ubuntu Trusty 的下載頁. 這邊有兩個版本, lxde ( Lightweight X11 Desktop Environment), 搭配 GUI 的版本. 另一個是 console (想當然耳, 就是只有 console 介面的版本). 選擇要下載的檔案後, 會先跳轉到軟體授權頁, 翻到最下面, 按 “I Agree”, 然後就會開始下載.

下載之後, 用以下命令, 寫入 micro sd card. 會要一些時間, 要耐心等候.

$ sudo umount /dev/sdb*

$ zcat 20150622-nitrogen-3.10.53_1.1.1_ga-trusty-en_US-lxde_armhf.img.gz | sudo dd of=/dev/sdb bs = 1M

$ sync

做完之後, 把 micro sd card 放進 card slot 之後開機. 就可以進入到登入畫面. 如果有掛螢幕, 也可以看到 nitrogen 的 ubuntu 登入畫面. 如果忘記插卡, 就會一直停留在 U-Boot 的畫面.

賭徒

 

朋友們都知道我不喜歡賭博. 不管是玩撲克牌或是打麻將, 甚至也不買樂透. 但是, 我確確實實是一個賭徒.

我舉一個例子, 我唸書的時候, 有一段時間常去電動玩具店, 玩賭博式的電玩, 那時還沒抓那麼兇. 有一段時間, 我站在小瑪莉機臺(就是那種有櫻桃, 柳丁, 西瓜, 的圖片, 然後一個紅點在那裡跑來跑去, 看停到那裡, 那個就是賠率)的前面觀察中獎的模式. 就是出大賠率之前, 它的落點和順序. 大約兩三個星期吧, 我觀察到一個特定的順序, 於是我開始等待, 等了幾天之後, 出現了那個順序, 剛好在玩的人也離開. 於是我連坐都沒有坐下來, 直接投錢, 押滿, 然後就錢一直滾下來. 那個機臺的最大賭注是 9, 最大賠率是 50, 就是大 BAR啦. 所以呢, 實得 9*50 – 9, 之後不只是那家電動玩具店, 甚至賭博性電玩我都沒再玩過.

我喜歡大賭注, 高賠率, 而且可以參與其中的 game.

最近遇到了一個這樣的 game. 也不知道算是主動, 或是被動的加入這個 game, 既然進來了, 而且, 這也觸動了我賭徒的靈魂, 我準備加入. 為了這個花了很多精神, 朝思暮想, 弄到有點憂鬱了.

第一個要考量的就是賭注. 你手上有多少籌碼? 如果還有時間, 你能或是你要再加多少籌碼? 你可以承受多少? 輸掉的有時候不是只有賭注, 籌碼. 當你在牌桌上看牌, 小孩在旁邊吵著要回家, 你已經輸掉了親情. 當你把精神都投入在這上面, 你已經輸掉了自己. 也許, 賭注根本就不只是金錢, 也許是 3 年的自由, 10 年的努力, 甚至是活下去的勇氣.

其次, 是賠率. 其實呢, 賠率是沒什麼意義的. 獎品和賭注可能根本不是同一類的東西, 那有賠率可言? 應該說, 贏得的獎品, 夠不夠吸引力 ? 這個吸引力, 能夠吸引你帶來多少籌碼. 也許是更大量的金錢, 也許是你朝思暮想的東西, 可是, 更多時候, 贏得的, 只是選擇未來的一把鑰匙.

I am in.

[RCS] Linux Version Control Tool

 

RCS (Revision Control System) 是 Linux 上的一個簡單的 Version Control 工具, 和其他的 Version Control 工具來比, 它的功能簡單, 沒有分散式版本管理能力. 但是因為它簡單, 所以如果是單機或單人作業, 它還是很好用的. 以下用一個簡單的例子來解釋.

安裝

$ sudo apt-get install rcs

設定

其實不需要設定. 不過 rcs 有一個特別的地方, 如果 source code 的目錄裡面, 有 RCS 這個目錄, 它會把它的檔案都放在這裡面. 這樣 source code 的目錄看起來就乾淨多了.

$ mkdir RCS

預備

既然是版本管理, 那當然就要有 source code, 這邊用一個很簡單的 print Hello World 的 c 程式做例子.

test.c :

image 

啟始

所謂的啟始, 只是把 source code 加入 RCS 的控管.

$ rcs –i test.c

然後, 這個檔案就會被加到 RCS.

image

rcs 會要求輸入一些說明, 這在後續參考時會有幫助. 譬如說修改那一個 bug, 加入那些功能.  

Check In

Version Control 的最重要兩個動作就是 check in/check out. check in 表示將版本送進version control 控管,check out 則是從 version control 取出版本.

$ ci test.c

image

check in 之後, rcs 會同時刪除目前的檔案.

Check Out

Cehck out 有兩種狀況,

第一個, 只是拿出來看看.

$ co test.c

image

check out 出來的檔案, RCS 會把它的屬性改成唯讀.

第二個, 拿出來修改.

$ co –l test.c

image

-l 是 lock 的意思, 這時候只有 check out 的人, 也就是檔案的擁有人可以修改. 同時, RCS 管理的檔案中, 這一個被 check out 的檔案, 也不能再鎖定, 進行修改.

check out 並鎖定之後, 就來修改看看, 隨便加入個訊息

image

然後 check in, 並加入一些說明.

image

查看修改歷程

software 就是一連串的修改過程, version control 需要知道這些過程:

$ rlog test.c

image

rlog 列出的第一段, 是 RCS 的一些設定資訊. 接下來是由近到遠的修改記錄, 這邊可以看到有兩個版本 1.1 是 Initial version, 1.2  是 add message

查看版本差異

$ rcsdiff –r1.1 –r1.2 test.c

image

這邊可以看到, 兩個版本的差異只是一行 printf

將版本號置入原始碼

RCS 可以將版本資訊代入程式碼中, 只要加上 $Id$

image 

check in 之後, 再 check out 出來看, $Id$ 已經展開成版本資訊.

image

這部份的版本資訊會隨著版本持續修改, 自動更新.

GNU make

GNU make 會自動尋找 RCS 中的檔案, 並且 check out 出來編譯.

$ make test

image

這邊可以看到, 目錄中只有 RCS 這個子目錄, 下 make 這個命令之後, make 自動取出 test.c, 編譯, 並且刪除暫存檔. 最後只剩下 test 這個執行檔. 這個感覺真的不錯.

[Motion] Motion 完整介紹

 

motion 是一個輕量級 (相對於 Zoneminder 而言), 而且功能強大的的應用軟體, 它可以在大多數的 Linux 上執行監控的任務.

motion 所支援的 camera

    • 任何 Linux 支援的 camera
    • 許多的 IP Camera
    • Axis camera
    • 而且能夠進行 pan 和 tilt 的操作

motion 內建了一個 HTTP server, 可以支援遠端設定, 以及線上觀看. motion 可以存 JPEG 檔案, 或是 MPEG. MPEG 的部份需要額外安裝 CODEC.

MPEG 的 CODEC 可以選用 ffmpeg 或是 libav-tools. 兩個是系出同門, 基本上差不多.

安裝

$ sudo apt-get install motion

$ sudo apt-get install libav-tools

設定 motion

motion 在啟動之後, 會載入 motion.conf, 它的載入順序是目前目錄, ~/.motion, 最後是 /etc/motion, 我們會把它放在 ~/.motion.

$ mkdir ~/.motion

$ sudo cp /etc/motion/motion.conf ~/.motion/

$ sudo chown motion:motion ~/.motion/motion.conf

另外建立一個目錄來存放影像檔

$ mkdir ~/motion-images

在 /var/run 下面建立一個 motion 目錄來放 PID 檔案

$ sudo mkdir /var/run/motion

motion 會建立一個名字是 motion 的 group, 以及名字是 motion 的 user, 要讓 motion 這個程式, 能夠以 motion 這個 user 的權限, 存取 v4l 的資源, 也就是 /dev/video*, 需要將 motion 加入 video 這個 group

$ sudo adduser motion video

然後就可以啟動

$ motion

這時候就可以透過 Firefox 連接到 192.168.1.7:8081, 看到 webcam 的影像

image

或者是 192.168.1.7:8080, 開啟 motion 的控制頁面

image

 

設定 IP CAM

目前手上沒有 IP Cam, 這部份之後再補上

設定 USB Camera

USB camera 可以自動連上, 但是預設值是 320x240, 雖然可以改, 但是要先知道 USB camer 的一些相關參數. 而這些參數, 是來自於剖析 USB 的 descriptor, 所以比較麻煩. 要透過 USB device 詢問去取得這些參數. 有一些軟體可以用來列出這些資訊. 這裡只用預設的的工具, 來取得 USB Camera 的 Width/Height.

$ lsusb

$ lsusb –s 001:002 –v egrep “Width|Height”

$ v4l2-ctl –info

$ v4l2-ctl –list-ctrls

$ v42l-ctl –set-ctrl brightness=200

$ v4l2-ctl –set-ctrl auto_gain=0

設定多個 Camera

設定多個 camera 的時候, 只要在 motion.conf 中, 增加 thread, 指向 thread 的 configuration file. 以下是 thread 1 的例子

videodevice /dev/video0
width 640
height 480
framerate 24
output_normal off
ffmpeg_video_codec mpeg4
target_dir ~/motion-images
