使用cmake源代码安装libnfc
- http://tiehichi.me/2017/07/04/archives/nfc_0/
源码安装
其实源码安装也很简单粗暴，在Raspbian上也没有遇到什么莫名其妙的问题。
首先安装CMake，如果已经安装了请忽略这一步：
然后sudo apt-get install cmakecd到libnfc的源码目录中，建立一个build文件夹，在build文件夹中进行编译安装：
至此libnfc安装完成。mkdir buildcd buildcmake ..makesudo make installsudo ldconfig

输电线路平断面图中杆塔上三条线分别代表什么
三条线
粗红线表示导线
紫线代表跨越线，定位时这条线必须高于被跨越的其他线路。
蓝线代表切地线，定位时这条线必须高于地面。
另外，这3条线都表示的是最大弧垂气象条件下的位置，最大弧垂气象条件有可能是最高气温，也有可能是最大覆冰时，这个在定位之前就要判别。

将dwg文件放到Google Map的思路
2 将dxf导入ArcGis，赋上坐标系，导出为shape文件；
3 使用ogr2ogr将shape文件转换为json格式；
ogr2ogr -t_srs EPSG:4326 -f "GeoJSON" ttt.json 2.shp
4 使用Python的geojson，获取json格式文件里的坐标点，转为国内地图使用的火星坐标系 ，并输出为json格式。
5 使用ogr2ogr，将json格式转换为kml格式。
ogr2ogr -f "KML" yxl.kml yongxinglu_huoxing.json
6 将kml文件导入Google Map。（在google drive中）
更新：将北京54 120度带的dxf文件转换为kml文件
ogr2ogr -t_srs EPSG:4326 -f "KML" -s_srs EPSG:2437 2.kml lhk.dxf
-t_srs 输出文件重新投影或者转换
-f 输出文件的格式
-s_srs 指定输入文件的坐标系
最后一个参数是输入文件，倒数第二个参数是输出文件的文件名。

转： 在命令行临时指定pip的源
经常在使用Python的时候需要安装各种模块，而pip是很强大的模块安装工具，但是由于国外官方pypi经常被墙，导致不可用，所以我们最好是将自己使用的pip源更换一下，这样就能解决被墙导致的装不上库的烦恼。
网上有很多可用的源，例如豆瓣：http://pypi.douban.com/simple/
最近使用得比较多并且比较顺手的是清华大学的pip源，它是官网pypi的镜像，每隔5分钟同步一次，地址为 https://pypi.tuna.tsinghua.edu.cn/simple
临时使用：
可以在使用pip的时候加参数-i https://pypi.tuna.tsinghua.edu.cn/simple
例如：pip install -i https://pypi.tuna.tsinghua.edu.cn/simple gevent，这样就会从清华这边的镜像去安装gevent库。
永久修改，一劳永逸：
Linux下，修改 ~/.pip/pip.conf (没有就创建一个)， 修改 index-url至tuna，内容如下：
[global] index-url = https://pypi.tuna.tsinghua.edu.cn/simple
windows下，直接在user目录中创建一个pip目录，如：C:\Users\xx\pip，新建文件pip.ini，内容如下
[global] index-url = https://pypi.tuna.tsinghua.edu.cn/simple

IronPython clr.AddReferenceToFile Error
问题：在脚本中可以执行，但在交互解释器中出错。
IronPython Tutorial
clr.AddReferenceToFile adds reference to the assembly specified by its file name. This function will load the assembly from the file regardless of the assembly version. As a result, it doesn't guarantee that the correct assembly version is being loaded. To guarantee that correct assembly version is being loaded, use clr.AddReferenceByName. Moreover, AddReferenceToFile requires that the assembly be located in a directory listed in sys.path.

Fixing an AVI index with mencoder
Fixing an AVI index with mencoder
Fixing an AVI index with mencoder
This is more a “note to self”, but I’m sure others find it useful as well.
Quite often I run across AVI files with a broken index. That index is used in media players to seek rapidly in the movie file. Without an index or with a corrupt index, seeking either does not work at all or takes a long time.
mencoder, which is available on almost any platform, allows you to massage AVI files besides tons of other operations on a never-ending list of video formats.
Here’s the command to repair a broken AVI index (I used the mplayer/mencoder version that comes with the FreeBSD ports collection):
$ mencoder -idx in.avi -ovc copy -oac copy -o out.avi

使用mailx发送qq邮件
本文出自 “宁静致远” 博客，
请务必保留此出处http://irow10.blog.51cto.com/2425361/1812638
mailx安装我就不介绍了，很简单！我先介绍下系统的版本和mailx的版本
[root@localhost ~]# mailx -V
12.4 7/29/08
[root@localhost ~]# cat /etc/issue
CentOS release 6.8 (Final)
Kernel \r on an \m
mailx的配置文件在/etc/mail.rc（我是rpm安装的）
在配置文件中添加下面的代码（passwd写开通smtp客户端给的授权码）
set from=usernam@163.com
set smtp=smtp.163.com
set smtp-auth-user=username@163.com
set smtp-auth-password=passwd
set smtp-auth=login
测试下是否可以使用
cat /opt/tesh |mailx -v -s 'hello' '*****@163.com'
测试发现有时能发送，有时会退信并报以下错误：
554 DT:SPM 163 smtp3,DdGowACX1p2fRn9X_lIIAA--.2018S2 1467958944,please see http://mail.163.com/help/help_spam_16.htm?ip=*.*.*.*&hostid=smtp3&time=1467958944
smtp-server: 554 DT:SPM 163 smtp3,DdGowACX1p2fRn9X_lIIAA--.2018S2 1467958944,please see http://mail.163.com/help/help_spam_16.htm?ip=*.*.*.*&hostid=smtp3&time=1467958944
"/root/dead.letter" 0/0
. . . message not sent.
554 DT:SPM 发送的邮件内容包含了未被许可的信息，或被系统识别为垃圾邮件。请检查是否有用户发送病毒或者垃圾邮件
查了下原因，因为163反垃圾邮件设置的原因，所有我采用了qq邮箱及hostmail
qq邮箱
set from=224******53@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=224******53@qq.com
set smtp-auth-password=euia********chb #授权码
set smtp-auth=login
错误提示：
530 Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28
smtp-server: 530 Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28
"/root/dead.letter" 19/438
. . . message not sent
于是我改了下配置文件添加了几个参数
set from=224******53@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=224******53@qq.com
set smtp-auth-password=euia********chb
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/etc/pki/nssdb/
邮件发送成功，在/etc/pki/nssdb/有证书文件
当然还有两个方式可以获取证书文件
mkdir -p /root/.certs/
echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qq.crt
certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -L -d /root/.certs
然后mail.rc的配置文件改成
set from=224******53@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=224******53@qq.com
set smtp-auth-password=euia********chb
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/root/.certs
有些邮箱无法通过上述方式获取证书，我们可以在装有火狐浏览器的服务器中把证书拷贝过来
[root@localhost test]# cd /home/test/.mozilla/firefox/twmiqm5n.default/
[root@localhost twmiqm5n.default]# ll *db
-rw-------. 1 test test 65536 Jul 7 16:29 cert8.db
-rw-------. 1 test test 16384 Jul 7 16:29 key3.db
-rw-------. 1 test test 16384 May 28 20:38 secmod.db
把这个三个文件拷贝到指定文件下。比如：/root/.certs1
set from=224******53@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=224******53@qq.com
set smtp-auth-password=euia********chb
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/root/.certs1
mailx的操作还是蛮简单的，就是一直报一个错误
Error in certificate: Peer's certificate issuer is not recognized.
证书没有获得认可
解决方法：找个存放证书的目录
[root@localhost .certs]# pwd
/root/.certs
[root@localhost .certs]# ll

-rw-------. 1 root root 16384 Jul 7 16:24 secmod.db
[root@localhost .certs]# certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ./ -i qq.crt
Notice: Trust flag u is set automatically if the private key is present.
这样就不会报错了。

sendEmail
下面来介绍sendEmail的使用
wget http://caspian.dotconf.net/menu/Software/SendEmail/sendEmail-v1.56.tar.gz
tar -zxvf sendEmail-v1.56.tar.gz
cd sendEmail-v1.56
mv sendEmail /usr/local/bin/
yum -y install perl-IO-Socket-SSL openssl-perl openssl-devel
sendEmail就可以使用了。应为sendEmail没有配置文件，所以在发送邮件的时候需要填上发件人的账户密码，没有mailx方便.
这是我们需要脚本辅助
#!/bash/sh
from_email='username@hotmail.com'
smtp='smtp-mail.outlook.com:587'
title='标题'
to_email=`username@qq.com`
passwd='passwd'
body=`cat test`
/usr/sbin/sendEmail -o tls=yes -f "$from_email" -s "$smtp" -u "$title" -o message-content-type=text -o message-charset=utf8 -t "$to_email" -xu "$from_email" -xp "$passwd" -m "$body"
以上是个简单的脚本，当然标题和内容以及发件人你都可以传参进来。这样的话就不会再命令行中暴露密码。

mailx安装我就不介绍了，很简单！我先介绍下系统的版本和mailx的版本
[root@localhost ~]# mailx -V
12.4 7/29/08
[root@localhost ~]# cat /etc/issue
CentOS release 6.8 (Final)
Kernel \r on an \m
mailx的配置文件在/etc/mail.rc（我是rpm安装的）
在配置文件中添加下面的代码（passwd写开通smtp客户端给的授权码）
set from=usernam@163.com
set smtp=smtp.163.com
set smtp-auth-user=username@163.com
set smtp-auth-password=passwd
set smtp-auth=login
测试下是否可以使用
cat /opt/tesh |mailx -v -s 'hello' '*****@163.com'
测试发现有时能发送，有时会退信并报以下错误：
554 DT:SPM 163 smtp3,DdGowACX1p2fRn9X_lIIAA--.2018S2 1467958944,please see http://mail.163.com/help/help_spam_16.htm?ip=*.*.*.*&hostid=smtp3&time=1467958944
smtp-server: 554 DT:SPM 163 smtp3,DdGowACX1p2fRn9X_lIIAA--.2018S2 1467958944,please see http://mail.163.com/help/help_spam_16.htm?ip=*.*.*.*&hostid=smtp3&time=1467958944
"/root/dead.letter" 0/0
. . . message not sent.
554 DT:SPM 发送的邮件内容包含了未被许可的信息，或被系统识别为垃圾邮件。请检查是否有用户发送病毒或者垃圾邮件
查了下原因，因为163反垃圾邮件设置的原因，所有我采用了qq邮箱及hostmail
qq邮箱
set from=224******53@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=224******53@qq.com
set smtp-auth-password=euia********chb #授权码
set smtp-auth=login
错误提示：
530 Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28
smtp-server: 530 Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28
"/root/dead.letter" 19/438
. . . message not sent
于是我改了下配置文件添加了几个参数
set from=224******53@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=224******53@qq.com
set smtp-auth-password=euia********chb
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/etc/pki/nssdb/
邮件发送成功，在/etc/pki/nssdb/有证书文件
当然还有两个方式可以获取证书文件
mkdir -p /root/.certs/
echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qq.crt
certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -L -d /root/.certs
然后mail.rc的配置文件改成
set from=224******53@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=224******53@qq.com
set smtp-auth-password=euia********chb
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/root/.certs

FFmpeg实用命令：音频、视频格式转换和其它操作
FFmpeg实用命令：音频、视频格式转换和其它操作
下面命令从mp4文件中提取出MP3音频:
ffmpeg -i yourvideo.mp4 -vn -ab 128k outputaudio.mp3
-vn用来提取声音，-ab指定存储为128Kbps mp3格式，可以指定256K或其他码率。
Cutting small sections
To extract only a small segment in the middle of a movie, it can be used in combination with -t which specifies the duration, like -ss 60 -t 10 to capture from second 60 to 70. Or you can use the -to option to specify an out point, like -ss 60 -to 70 to capture from second 60 to 70. -t and -to are mutually exclusive. If you use both, -t will be used.
Note that if you specify -ss before -i only, the timestamps will be reset to zero, so -t and -to have not the same effect. If you want to keep the original timestamps, add the -copytsoption.
The first command will cut from 00:01:00 to 00:03:00 (in the original), using the faster seek.
The second command will cut from 00:01:00 to 00:02:00, as intended, using the slower seek.
The third command will cut from 00:01:00 to 00:02:00, as intended, using the faster seek.
Example:

ffmpeg -ss 00:01:00 -i video.mp4 -to 00:02:00 -c copy cut.mp4 ffmpeg -i video.mp4 -ss 00:01:00 -to 00:02:00 -c copy cut.mp4 ffmpeg -ss 00:01:00 -i video.mp4 -to 00:02:00 -c copy -copyts cut.mp4If you cut with stream copy (-c copy) you need to use the -avoid_negative_ts 1 option if you want to use that segment with the concat demuxer .
Example:
ffmpeg -ss 00:03:00 -i video.mp4 -t 60 -c copy -avoid_negative_ts 1 cut.mp4
Time unit syntax
Note that you can use two different time unit formats: sexagesimal (HOURS:MM:SS.MICROSECONDS, as in 01:23:45.678), or in seconds. If a fraction is used, such as 02:30.05, this is interpreted as "5 100ths of a second", not as frame 5. For instance, 02:30.5 would be 2 minutes, 30 seconds, and a half a second, which would be the same as using 150.5 in seconds.2017年2月22日星期三
What are AcDbCurve/Curve Parameters? ObjectARX/.NET
What are AcDbCurve/Curve Parameters? ObjectARX/.NET
By Philippe Leefsma
Please can you explain what Parameters are?
In simple terms, the parameter of a curve defines a 0-n floating point value indicating point positions on a curve.
Lets use a polyline as an example of what to expect from a parameter value.
If we have a polyline which has 5 points, and each of the 4 lines are different in length. If we call AcDbCurve::getStartParam() we will be returned a value of 0, if we call AcDbCurve::getEndParam() we will get a value of 4, if we extract the 2nd polyline point and call AcDbCurve::getParamAt() we will be returned a parameter value of 1. So you can see that in the case of a polyline, the parameter values directly represent each of the start and end points of the Polyline.
Parameters are very powerful, for instance, I can extract the halfway point between p1 and p2 by calling AcDbCurve::getPointAtParam(0.5) or the third of a distance between p3 and p4 by calling AcDbCurve::getPointAtParam(2.33333).
Another point to mention is that parameter values, although define a 0-n floating point value indicating point positions on a curve, are designed to best fit the needs of the curve being implemented. For example, the polyline example above uses parameter values as start and end point positions, this is a very efficient way to use parameters for a polyline and indeed makes logical sense, but for a circle the parameter values correspond to a radian increment around the circle. So, for a polyline the parameter value is non-uniform whereas the circle uses a uniform parameter value.
