Recover Acrobat XI favourite commands settings from offline Windows 8.1 Registry File on external HDD

I backup entire Windows 8.1 partition to an external hard drive and re-installed Windows.

I tried to recover my Acrobat XI common tool settings from backup instead of customizing them again.

Prepare:

I don’t know where Acrobat stores these settings. By google, in windows 8.1, Acrobat puts files in this location:

C:UsersUser_NameAppDataRoamingAdobeAcrobat11.0Preferences

However I didn’t find any useful files related with Common Tools settings. I guess that the settings are in Windows Registry.

Extract offline registry from my backup external hard drive

1. The Tool I am using: RegFileExport v1.06 

http://www.nirsoft.net/utils/registry_file_offline_export.html

2.Windows put registry file here since Vista:

Current User Settings:

1
Users%username%NTUSER.DAT

Computer Settings:

1
WindowsSystem32Config

3. Extract: In windows command line (cmd):

RegFileExport “J:UsersMyNameNTUSER.DAT” “E:OldReg.txt”

4.  Export my current Acrobat registry at “[HKEY_CURRENT_USERSoftwareAdobeAdobe Acrobat11.0” to temp.reg

5. Comparing content in OldReg.txt and temp.reg using Notepad++ and compare plugin, I found that Acrobat puts settings related to Common Tools at

“[HKEY_CURRENT_USERSoftwareAdobeAdobe Acrobat11.0AVGeneralcFavoritesCommandsDesktop]”

6.Extract these settings from my old registry and import in the current registry. Success!

7. Here is my example settings – AdobeCommon.reg

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USERSoftwareAdobeAdobe Acrobat11.0AVGeneralcFavoritesCommandsDesktop]
"a0"="Text"
"a1"="Highlight"
"a2"="RotatePages"
"a3"="TouchUpEditPDFTool"
"a4"="FreeTextTypewriter"
"a5"="Ink"

Acer Aspire V5-473P-5602 风扇调速

换了个本儿,写一个Log:

Acer Aspire V5-473P-5602 i5-4200U,无独立显卡, 使用起来感觉风扇略吵. 找不到现成可用的风扇调速软件.

使用RWEverything (http://rweverything.com/) 读取系统Embedded Controller (EC)试图找到控制风扇方法.

473P拆机后发现,设计时的双风扇在此机器上只有一个(假如键盘向上,这个风扇在右边), 473PG独显版本才有两个风扇. 感觉这单个风扇不足安静的将CPU温度控制在合理范围.

使用上述软件读取EC Register后发现,貌似这台机器的设计不同于一般笔记本, 似乎没法直接控制风扇的转速,只能按照档位调节,貌似只有少数笔记本这么设计,比如Asus Zenbook和Thinkpad x些列12寸的个别机器.

EC Register 上, 目前研究下来,可能的分配是:

Hex地址: (对应值均为Hex)

55 -> 控制风扇档位 -> :  00 风扇关闭; 01-04 由低到高的4个风扇档位,05貌似这时候风扇速度已经最大了,虽然数字还可以调高,但是没啥变化了; 1F 这时候风扇是最大转速而且系统不会更具CPU温度自动降档位了. 在其他数值,系统会更具温度很快的降下档位

56-> CPU图形核心温度

58->CPU Package温度

5C->风扇转速 -> 目前发现数值大约是以下规律: 00 风扇关闭 09 最低转速 1B最高转速. 听风扇声音, 和实际转速的对应关系可能是 Decimal数值 x 100, 也是就900RPM 到 2700 RPM

5D->数值变化没规律,但是是紧接着5C,怀疑是未安装的那个风扇的转速读数 Continue reading Acer Aspire V5-473P-5602 风扇调速

Photograph the Milky Way and Star Trail photos

For my future reference:

The Milky Way photo Tips:

1. Look at sky report, try to avoid moon, eg, Sky Report in Southern Cal: http://www.griffithobs.org/skyreport.html

2. Avoid city, find dark place.

3. Use some apps on the phone/computer to identify stars: Stellarium, Startracker,.etc

4.DSLR,Tripod,Shutter Release. Use wide angle: 24mm, 14mm,.etc

Then ->Compose photo->Mirror Lock up->Shutter Release(Or self-timer)

5. Manual mode, set manual focus (MF) to infinity or far away

set 30 sec exposure time

Use max aperture available: f/2.8 f/1.4 .,etc

ISO:   if F/1.4 -> 1600  if F/2.8 -> 6400

6. Set White balance to Tungsten (try around 4000k) or adjust later in photoshop. Also increasing contrast.

Star Trail tips:

1.Using the above method to get multiple shoots, eg: 100 shoots. (It’s better to point at the North Star) Use some shutter release cable, or use the camera build-in interval shooting function(if have).

2. Using Photoshop: File->Scripts->Load files into stack

3. choose all the layers and set “Layer Blending options” to “lighten”

3. Adjust other parameters as you like.

Done

几篇科幻短篇的读书笔记摘抄

科幻有时候比想象的要深刻

《弗兰肯斯坦》

(英) 玛丽·雪莱

“他叫维克多.弗兰肯斯坦,是伦敦一所大学的生物学教授…他早出了一个人’人’.’他’脸色想枯萎的黄叶,两片嘴唇呈直溜溜的一条黑线,眼睛深陷在眼窝里,身高2.5米,十足一个大怪物。”

“最后,他忍无可忍,对怪物大吼一身:“滚!”怪物又看了他一眼,眼神中似有一丝留念,然后扭头走了。”

“他实在忍不住了,随手就把快要完工的女怪物砸了个稀烂。同时,他听到窗外传来怪物充满绝望和仇恨的吼叫,凄惨极了。”

“可是把我逼成这个样子,难道人们,包括您就没有责任吗?为什么你们不能相信我、宽容我、接受我?一始我也是充满仁慈的啊,您已经离开了人世,我不愿意在受悔恨与痛苦的折磨了。那怪物说满,纵身一跃,跳进冰海里,永远消失了”

《重现》

西帕特

“他闭上眼睛:但愿这最后的几分钟从未发生过。/ 哈罗德惊异的眨着眼睛。他又一次站在厅堂的尽头,而瓷马和玻璃柜却都安然无恙。”

“当别人听不到他们说话声音的时候,菲夫人就咬牙切齿地说,“我为什么要生下你呢!”哈罗德闭上了眼睛,于是……”

(*没有后悔药,后悔的结果就是消失)

《天幕坠落》

大卫·赫尔

“到那时候,姐姐真的恨起爸爸来了。她很少理睬爸爸,而且一开口,就数落他的纹身多么丑,他的玩笑多么无聊,他失业后长得多么肥胖。”

“爸爸没有凑到足够的钱救妈妈的命,不过,他卖皮肤和器官所得的15万美元却足够给我们在地下城买一小套住房,并在我们长大成人前给我们提供生活费。”

《图金的时间》

德·比连金

“究竟是他失去了客观时间、还是记忆失灵,主观时间出了问题,这就说不清了。不过,图金明白了这一点,在他提前进入未来时间的时候,他发现那是的生活与现在和过去毫无二致,已然是那么平淡无奇,按部就班”

“他不但不能确定日子、时间,他甚至不能确定自己,不明白自己为什么生存。”

读村上春树的几个短篇摘录

村上春树
1949, 作品受欧美文化影响. 具有都市感,时代感. 代表作《挪威的森林》

《电视国民》

“星期日的黄昏…通常都是感觉到两遍的太阳穴里面一公分或一公分半的地方,有柔软的白色肉团产生奇妙的痉挛.那种感觉简直就像想从那团肉的中心抽出一条无形的线,有个人在远处拉住线的一端,轻轻的拉紧一般.”

“星期日的下午,一切事物看起来都像用缩尺缩小般地慢慢变小.简直就像”电视国民”一般.”

“”电视国民”从一开始就无视我的存在”

《百分百女孩》

“两人恰在路中间失之交臂.失却的记忆的微光刹那间照亮两颗心.两人胸口陡然悸颤,并且得知:她对我是百分之百的女孩.他对我是百分之百的男孩. 然而两人记忆的烛光委实过于微弱.”

《没落的王国》

(这篇文章其实是写主角的多年前朋友Q的..和没落王国没啥关系,但又有关系)

“一个强大的王国褪色的时候,比二流共和国崩溃的时候,还要感伤”

《困》

“汤匙从我手上滑落,碰到餐具边缘,发出叮当一声巨响”

“汤盘正上方月三十公分的地方,漂浮这一团乱行的白色气体,正对我楠楠说道:”没关系,没关系,你不用忍耐,好好睡吧””

《1963/1982年的依帕内玛姑娘》

“相信总有一天,我会在遥远的世界一个奇妙的场所遇见我自己.而且,希望那最好是一个温暖的场所,如果那里也有几罐冰啤酒的话,那就更没话说了.”
