今天碰到一件郁闷的事情

今天是2008年8月1日,想想看,来江阴农商行做项目也快3个月了（5月4日来的），

由于进入银行大楼要门卡，才可以上楼，以前经常叫保安开一下门，也熟悉了，

有时候，看到有银行的人正好进去，我们几个就跟着进去了，

感觉这样就不用麻烦银行的保安了，毕竟保安是一个非常好的人，

还经常跟我们打招呼，还问我们什么时候项目做完之类的问题。

今天中午跟平常一样，看到一个银行的人来了，我们就没有叫保安了，想跟他一起进去，可以这银行的职员，

他问我们说：“你们到几楼？”

我说:“三楼”

他（非常凶的）说：“那你叫三楼的人下来开门，不要老是跟着别人的后面！”

我们没有说什么，马上就去叫保安过来开门了，保安说他还不让你们进去，笑了笑给我们开门了，就说这样的人都有。

我们当时感觉今天怎么碰到这样的人了，是不是这个人喝醉酒了，这么凶！

但是明细没有喝醉的样子，在外面做点项目，我们没有必要跟这样的人计较，

也许他也是做得非常对的，对银行负责嘛，免得不当人员混入银行。

上午接到一电话,要下午过去面试的,说因为领导下午要来检查,务必准时到达.公司叫信义科技,说在罗湖那边.挂断了电话,心里还在纳闷时,就顺势查了一下网上的和电话里所说的信义科技不在同一个地方,后来又查了刚接的电话25092883,没想到,网下就出来这些:

我上次接到个这样的面试通知,我问他们在什么地方,说是在群星广场15楼,叫下午4点过去面试,还说下午公司领导要来检查工作,让到了打他电话,说他姓陈,电话是25092883,我在网上查了我投的简历中没有地址在华强北群星的,下午去了科技园有点累就懒得去华强北面试了,4:30我打了好几个电话过去一直没人接.

还有别的同学也接到这种电话,看来骗的人还真不少

[色綵的魅力](2008/5/29 10:40:56)
信仪科技昨天上午也打电话给我了，说要我下午4点去面试，还说下午公司有领导检查工作要我到楼下给她电话，我查了一下，我也没投过这家公司哦，她说在赛格科技园，可我网上搜到在罗湖，正好下午有事情耽误了没去，要不也上当了。不知道这些企业在发布招聘信息时，人才市场有没有核实企业真实资料呢？再这样下去，这个社会就......

我也差点被骗了.上午接到２５０９２８８３这个号码打来的电话叫我下午３点去面试，是一个男的打来．因为当时在公车上有点吵具体什么公司就记不大清楚了，公司地址在西武大厦，还再三叮嘱我一定要准时，到了楼下先给他们电话让他们安排一下．
我回来看看自己投递的简单，没有在西武大厦的公司投过，后来把电话号码百度了一下，看到这贴子．还真谢天谢地．我还好没去．
刚刚三点整的时候，我打电话过去说我到了楼下，是个女的接．问了早上是她通知我还是她同事，还问我的名字，说公司领导在开会，让我在西武大厦旁边的建行门口等他们的人事经理，他和我谈一下工作的情况，问我穿什么衣服．我说我穿白色．挂了电话大概四五分钟左右，他们又打过来了．我没接．想想就后怕啊．．．．
大伙可都得注意了．

jsp页面中不能显示图片

xiejiaohui — Fri, 13 Jun 2008 14:29:43 +0800

在 AIX 5.3 操作系统，WebSphere 5.1 应用服务器中发布企业应用

由于在登录的页面中要用到校验码（图片）来防止恶意用户用软件的登录，

但是把应用发布以后，发现 jsp 页面中的图片无法显示，

解决办法：

登录 websphere 的管理端： http://127.0.0.1:9090/admin

选择步骤如下：

服务器－应用程序服务器－ server1 －进程定义－ Java 虚拟机－高级 Java 虚拟机设置

在一般 JVM 自变量中输入

-Djava.awt.headless=true

不要输错了，否则 websphere 会启动失败（启动不了）。

然后重新启动 websphere 5.1.

修改照片的文件大小

以下步骤修改照片，使得照片变小：

一用鼠标右键点击你要修改的照片，选择编辑，windows XP 将用画图打开你要修改的照片。

二选择图像菜单下的拉伸/扭曲菜单。

三在弹出的拉伸/扭曲对话框中，把拉伸中的水平和垂直由原来的 100% 修改为 50% 下面的扭曲参数不变，然后选择确定按钮，照片的大小就变得小了很多了，并且照片并没有变模糊，照片还变得更清楚了。

四重复第三步，直到照片满足你的要求大小为此。

五保存照片。

svn conf 目录中简单配置

xiejiaohui — Tue, 06 May 2008 22:23:47 +0800

文件

passwd

### This file is an example password file for svnserve.
### Its format is similar to that of svnserve.conf. As shown in the
### example below it contains one section labelled [users].
### The name and password for each user follow, one account per line.

[users]
admin=123456
xjh=654321

文件

authz

### This file is an example authorization file for svnserve.
### Its format is identical to that of mod_authz_svn authorization
### files.
### As shown below each section defines authorizations for the path and
### (optional) repository specified by the section name.
### The authorizations follow. An authorization line can refer to a
### single user, to a group of users defined in a special [groups]
### section, or to anyone using the '*' wildcard.  Each definition can
### grant read ('r') access, read-write ('rw') access, or no access
### ('').

# [groups]
# harry_and_sally = harry,sally
[groups]
user = xjh,admin

[sdbcc:/]
* = rw

[sdbcc:/sdbcc_base]
* = rw

# [/foo/bar]
# harry = rw
# * =

# [repository:/baz/fuz]
# @harry_and_sally = rw
# * = r

文件

svnserve.conf


### This file controls the configuration of the svnserve daemon, if you
### use it to allow access to this repository.  (If you only allow
### access through http: and/or file: URLs, then this file is
### irrelevant.)

### Visit http://subversion.tigris.org/ for more information.

[general]
### These options control access to the repository for unauthenticated
### and authenticated users.  Valid values are "write", "read",
### and "none".  The sample settings below are the defaults.
anon-access = none
auth-access = write
### The password-db option controls the location of the password
### database file.  Unless you specify a path starting with a /,
### the file's location is relative to the conf directory.
### Uncomment the line below to use the default password file.
password-db = passwd
### The authz-db option controls the location of the authorization
### rules for path-based access control.  Unless you specify a path
### starting with a /, the file's location is relative to the conf
### directory.  If you don't specify an authz-db, no path-based access
### control is done.
### Uncomment the line below to use the default authorization file.
#authz-db = authz
### This option specifies the authentication realm of the repository.
### If two repositories have the same authentication realm, they should
### have the same password database, and vice versa.  The default realm
### is repository's uuid.
realm = sdbcc

安装Eclipse SVN plugin(Subclipse)

xiejiaohui — Sun, 23 Mar 2008 12:34:08 +0800

来源：http://www.svn8.com/svnpz/20080225/160.html

这里介紹Eclipse的SVN Plugin，叫做Subclipse,官方网站的下载地址在http://subclipse.tigris.org/，也提供了update site http://subclipse.tigris.org/update。
Eclipse的使用者可以通过Eclipse的插件自动下载和更新功能来安装这个插件，在Eclipse的菜单中选择Help->Software Updates->Find and Install-> Search for new features to install ->New Remote Site。URL中就输入http://subclipse.tigris.org/update，Eclipse就会自已安装上了.
安装完成后，在Eclipse的plugins中就会多了5个包，命名为org.tigris.subversion.*的都应该是了。打开Eclipse,window->show view窗口中多了一个SVN文件夹，到此就证明svn插件成功的安装上了。具体的使用方法，在Eclipse的Help中有详细的帮助Subclipse - Subversion Eclipse Plugin，教你一步一步的使用SVN的客户端了。如果你对subversion想进行深入的了解，那么看看help中的Version Control with Subversion一定有所收获，通过本人的观察，这份文档和sbuversion安装文件中提供的官方文档一样，这里看起来就更舒服些了。

请问深圳的准生证在哪办理？

户口所在地开初婚未育的证明,拿上这个证明到居住地所属社区盖章,
再到街道办事处计生办盖章,以上步骤盖三个章就算是把你的初婚未育证明了,
然后再带双方身份证、户口本、结婚证、结婚证上贴的一样的照片2张去女方户口所在地的计划生育办公室办理，比较好办理，
当场即可拿证，不收费；
我们这里的政策是出生前出生后都可以办理的，
具体期限你可以打电话先和计生办的联系好。

DB2中文版控制中心显示不正常

环境 [产品] DB2 UDB
[平台] Windows
[版本] 7.x
问题 DB2中文版控制中心显示不正常
解答如果在简体中文下发现控制中心显示不正常，修改下DB2文件：
"\java\java12\jdk\jre\lib\font.properties.zh"
将"filename.\u5b8b\u4f53=simsun.ttf" 替换为 "filename.\u5b8b\u4f53=simsun.ttc" 。

是指DB2的安装目录，如C:\Program Files\SQLLIB
