[ubuntu] VIM 用法

選取
v 小寫

選取後可用以下方式操作：
d 刪除選取區內容。
y 複製選取區內容。


/etc/vim/vimrc
插入space取代Tab
:set expandtab

Tab = 4 space
:set tabstop=4

程式縮排需要space的個數
:set shiftwidth=4

:w 令存新檔

[ubuntu] Byobu

F2 - Create a new window
F3 - Move to previous window
F4 - Move to next window
F6 - Detach from this session
F7 - Enter copy/scrollback mode
F8 - Re-title a window
F9 - Configuration Menu
F12 - Lock this terminal

alt + page up 往上捲動視窗
alt + page down 往下捲動視窗

Q: Putty 中使用Byobu F2~F4無效 
Ans: "Terminal" -> "Keyboard" -> "The Function keys and keypad" 選用 "Xterm R6" 便可。

[ubuntu] grep 用法

grep --help
用法: grep [選項]... 樣板 [檔案]...
Search for PATTERN in each FILE or standard input.
PATTERN is, by default, a basic regular expression (BRE).
Example: grep -i 'hello world' menu.h main.c

Regexp selection and interpretation:
  -E, --extended-regexp     PATTERN is an extended regular expression (ERE)
  -F, --fixed-strings       PATTERN is a set of newline-separated fixed strings
  -G, --basic-regexp        PATTERN is a basic regular expression (BRE)
  -P, --perl-regexp         PATTERN is a Perl regular expression
  -e, --regexp=PATTERN      use PATTERN for matching
  -f, --file=FILE           obtain PATTERN from FILE
  -i, --ignore-case         ignore case distinctions
  -w, --word-regexp         force PATTERN to match only whole words
  -x, --line-regexp         force PATTERN to match only whole lines
  -z, --null-data           a data line ends in 0 byte, not newline

Miscellaneous:
  -s, --no-messages         suppress error messages
  -v, --invert-match        select non-matching lines
  -V, --version             print version information and exit
      --help                display this help and exit
      --mmap                ignored for backwards compatibility

Output control:
  -m, --max-count=NUM       stop after NUM matches
  -b, --byte-offset         print the byte offset with output lines
  -n, --line-number         print line number with output lines
      --line-buffered       flush output on every line
  -H, --with-filename       print the filename for each match
  -h, --no-filename         suppress the prefixing filename on output
      --label=LABEL         print LABEL as filename for standard input
  -o, --only-matching       show only the part of a line matching PATTERN
  -q, --quiet, --silent     suppress all normal output
      --binary-files=TYPE   assume that binary files are TYPE;
                            TYPE is `binary', `text', or `without-match'
  -a, --text                equivalent to --binary-files=text
  -I                        equivalent to --binary-files=without-match
  -d, --directories=ACTION  how to handle directories;
                            ACTION is `read', `recurse', or `skip'
  -D, --devices=ACTION      how to handle devices, FIFOs and sockets;
                            ACTION is `read' or `skip'
  -R, -r, --recursive       equivalent to --directories=recurse
      --include=FILE_PATTERN  search only files that match FILE_PATTERN
      --exclude=FILE_PATTERN  skip files and directories matching FILE_PATTERN
      --exclude-from=FILE   skip files matching any file pattern from FILE
      --exclude-dir=PATTERN  directories that match PATTERN will be skipped.
  -L, --files-without-match  print only names of FILEs containing no match
  -l, --files-with-matches  print only names of FILEs containing matches
  -c, --count               print only a count of matching lines per FILE
  -T, --initial-tab         make tabs line up (if needed)
  -Z, --null                print 0 byte after FILE name

Context control:
  -B, --before-context=NUM  print NUM lines of leading context
  -A, --after-context=NUM   print NUM lines of trailing context
  -C, --context=NUM         print NUM lines of output context
  -NUM                      same as --context=NUM
      --color[=WHEN],
      --colour[=WHEN]       use markers to highlight the matching strings;
                            WHEN is `always', `never', or `auto'
  -U, --binary              do not strip CR characters at EOL (MSDOS)
  -u, --unix-byte-offsets   report offsets as if CRs were not there (MSDOS)

`egrep' means `grep -E'.  `fgrep' means `grep -F'.
Direct invocation as either `egrep' or `fgrep' is deprecated.
With no FILE, or when FILE is -, read standard input.  If less than two FILEs
are given, assume -h.  Exit status is 0 if any line was selected, 1 otherwise;
if any error occurs and -q was not given, the exit status is 2.

[android] 關於android 手機遊戲外掛

一點小小的想法!
經過實作確定可行!
python + adb command 實作andorid 手機的遊戲外掛

透過python 下adb command 截圖並pull 到電腦端

def getPic():
    os.chdir(adb)
    os.system("adb shell screencap -p /sdcard/screen.png")
    os.system("adb pull /sdcard/screen.png "+pic_dir+"pic.png")
    os.system("adb shell rm /sdcard/screen.png")

接著透過 python PIL lib 做圖形識別
接著對手機送touch event

def touch(x,y):
 os.chdir(adb)
 os.system("adb shell input tap "+str(x)+" "+str(y)) 

優點:
        實作超快! 省時省力
缺點:
        需要開著電腦!

[求婚] 關於求婚看板

關於求婚~~~
腦海中一直有一些想法, 想要做一些特別的東西.
翻翻過去的筆記對於單晶片一直很想要玩玩

用一個單晶片 控制LED燈 排成字的形狀~~ 順便求婚!!!
Good idea!!! 於是求婚看板就產生了!

小弟我念資工的會寫一點程式.
對於硬體的電子相關知識有點薄弱.
只好請教google 大師用最基本的東西做出這看板~~
在電路方面真的是土炮搞定他 線路很醜~~

我是寫SW的HW, 只是有時候我也會動手做一下 HW.

====== 製作篇 =======


2014.01.14
    上網找了好久看到這東西!
    Arduino Leonardo 單晶片開發版. 光看到李奧納多 名字就贏了
    對於我這軟體工程師來說 寫C code 這個簡單
    他有多個 IO (5V)  可以控制LED 字型
    而且也很便宜. 就決定是他了.

 

因為板子上IO 是 5V, LED電路打算用12V

請問google 大師發現繼電器這東西

就入手了一個8路繼電器

    關於LED, 在台灣一顆要價1~3元不等. 做看板保守估計要三四百棵LED

    加上預留實作失敗的部分, 看來這筆開銷很可觀! 

    在掏寶發現超便宜~~~

    所以一次買了三包 白 藍 紅~~ 各 1000顆!!!!

    平均一包 2XX 台幣. 只能說台灣賣真貴!!!

     開始擬草稿刻字~~~ 美工時間!!!

 

    阿母表示: 你不是要求婚! 應該要寫 佳圓嫁給我~~~

    HW: 對ㄟ! 可惡! 那個字很難刻ㄟ 要砍掉重練了!!!

2014_02_15

     努力刻字中~~~

    排版中~~

 

    最後拍板定案! 就這個! 

2014_02_16

    因為我超懶惰! 直接用焊槍打洞!! 超臭~~~

 

    有個雛形了~~~

2014_02_27 求婚看版

    努力焊接中~~~ 焊槍! 電表 鉗子 熱熔膠~~ 好忙! 好忙! 眼睛好花!

    試點燈~~~  成功!!!

    焊了兩三周!!! 終於~~ 完成四個字!

    不得不說! 這LED 超亮~~~

2014_03_08 求婚看板

    最後一個 "嫁" 字!  努力中~~

     完工!!! 電路有點醜! 哈~~~ 不管了!!!

 

     安裝繼電器!!!

     試點燈!!! 測試OK!

 2014_03_15 求婚看版

       今日目標:

       接上 Arduino Leonardo 開發版.

       測試OK! 可以透過寫程式 經由單晶片 控制 板子的亮暗!!! 閃爍!

 

    看板閃爍過於頻繁繼電器似乎被我搞壞

    一直秀逗不知道是不是磁化. 還是不能這樣搞!

    只好放棄閃爍了~~~~

    

    另外! 電源打開後他就開始閃爍感覺就很單調遜遜的!

    為了要能隨心所欲控制看板燈光

    所以這裡在板子上接一個紅外線接收器.

    拿沒有再用的遙控器來遙控看板!

    完工!!!

2014_07_05 求婚看板

    首先有人會問為什麼四個月沒動工! 

    答案: 因為想說還沒要求婚! 完成度也很高了~~~

    因為拿到婚戒了! 也該求婚了~~ 所以開始動工! 

    可惡! 放太久 上面有一層灰塵!!! 哈!!!

            

    電路板固定好了! 遙控的程式也寫好了~~~

    另外多接一個USB 接頭吃單晶片開發版的電

    接 USB抬燈 ~~~ 透過遙控器 讓他閃爍!!!

    求婚時! 只要插上電源! 拿著遙控器 就OK了!!!!

    測試OK!!!

    用了四百多顆LED終於~~~ 完工!!!

2014.07.11

    算算拿到婚戒到現在. 完完全全沒有機會去高雄!

    本想要請女友的好姊妹一起幫忙求婚!

    人算不如天算! 完全沒有時間！ 只好全部自己來~~

    在全黑的房間! 看板散發出藍光~~~

    我盡力了! 單眼完全拍不出那個感覺!!!

    用錄影的也錄不出來~~~

    現場看到是清晰 耀眼的字! 還有周圍藍藍的光線!!!   

    燈光美! 氣氛佳~~~

    在測試的時候拍到的!!!

    看板燈光打到人身上就是這感覺~~~

    女友最愛的藍色!!!

    求婚看板 + 玫瑰花束 + 求婚影片 + 鑽戒!

    終於~~~ Yes, I do.

來新竹多年～ 第一次朝聖！

近年來熱門的拍照景點, 其實離竹科不遠下班背著相機過去就可以了

六點多到已經滿滿的腳架下次要早點去！

心得：必備拖鞋涉水可以取得比較好的拍照角度．

地點：竹美路二段往68快速到路走到底右轉

遇到下面的插路穿過68快速道路即可看到

人超多～～滿滿都是腳架！看來要提早去卡位剛下山的色溫才是最美的！
就拍那半小時～～
