2、重新构造configure文件出错
./buildconf --force
Forcing buildconf
buildconf:checking installation…
buildconf:autoconf version 2.59 （ok）
buildconf:Your version of autoconf likely contains buggy cache code.
Running vcsclean for you.
To avoid this,install autoconf-2.13.
Can't figure out your VCS, not cleaning.
解决方法：编译安装autoconf-2.13
再将autoconf-2.13的auotconf文件至/usr/local/autoconf

How do I verify and diagnosis SSL certification installation from a Linux / UNIX shell prompt? How do I validate SSL Certificate installation and save hours of troubleshooting headaches without using a browser? How do I confirm I've the correct and working SSL certificates?

OpenSSL comes with a generic SSL/TLS client which can establish a transparent connection to a remote server speaking SSL/TLS. It’s intended for testing purposes only and provides only rudimentary interface functionality but internally uses mostly all functionality of the OpenSSL ssl library. For testing purpose I will use mail.nixcraft.net:443 SSL certificate which is issued by Go Daddy.

 Last month we released the Beta of VS 2010 Service Pack 1 (SP1). You can learn more about the VS 2010 SP1 Beta from Jason Zander’s twoblog posts about it, and from Scott Hanselman’s blog post that covers some of the new capabilities enabled with it. You can download and install the VS 2010 SP1 Beta here.

Last week I blogged about the new Visual Studio support for IIS Express that we are adding with VS 2010 SP1. In today’s post I’m going to talk about the new VS 2010 SP1 tooling support for SQL CE, and walkthrough some of the cool scenarios it enables.

In most cases you'll want to create your database and it's schema as part of your applications first deployment. Depending on the scenario, you may create it on the client, or create it on the server, do the initial sync, then stream the file down to the client pre-populated.

Why would you create the database on the fly, rather than ship the initial database with your app?

While you could create the empty shell, and deploy it, you'll almost never want to start with a database that has data? Why? While in development, you'll have some set of data. Months later, when another user first installs your app that data may no longer be valid. Since most sync systems don't track deletes forever, you could wind up with data that is very stale, and now way to effectively update it.

在linux的文字窗口中，使用telnet，有时会发现输入的中文会变成乱码，
此时加入参数 -8 就可以解决，例如：

telnet -8 bbs.xxx.xxx
也可以设 ~/.telnetrc 来解决，把底下设定加入 ~/.telnetrc 就可以了，
下次telnet就不用再加参数 -8

How to build jpegsrc.v6b on 64-bit Linux machines
jpegsrc is no longer maintained and has not been updated since the Clinton administration. This is odd considering how critical this library is to so many applications.

If you are trying to build on a 64-bit Linux machine you will probably get this error during the ./configure step:

checking host system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized
