近日 Google 的 Chrome 浏览器宣布从最新的 Chrome 21.x 以及更高的 Chrmoe 22.x 版本开始默认只允许从 Chrome Web Store 下载安装扩展程序, 而众多未登陆 Web Store 的无论是扩展插件还是应用程序抑或 Greasemonkey 等 JS 脚本都被排除在外。
当然,按照官方给出的解释是处于安全考虑,而刚好最近被爆出的 Chrome Web Store 中的 Proxy Switchy Plus 汉化版等存在流氓行为也表明这项举措也无可厚非,但毕竟还是给很多使用 Greasemonkey 或 Stylish 脚本的用户造成了很大的不便,那么现在应当如何在谷歌浏览器安装 Web Store 外的第三方扩展程序呢?下面有两个方法。
8. Chrome 的 user agent 自定义功能可以伪装成其他浏览器。如果网速非常慢,伪装成智能手机会有明显改观:很多网站提供了轻量级的移动版界面。要自定义 user agent 字符串,可以打开开发工具(Windows/Linux 下:Ctrl+Shift+I,Mac 下:Command-Option-I),点击窗口底部的“设置”按钮,点选“user agent”下的“更改 user agent”,在下拉框中选择“Android 4.0.2 – Google Nexus”或“iPhone – iOS 5.0”,并取消选中“更改设备参数”。
9. 如果你正在使用的 DNS 服务器非常慢,改用 Google Public DNS 便成为加快浏览速度简单有效的方法。Google 解释说,“DNS 协议是网络基础架构极其重要的一环,它为互联网提供电话簿服务:计算机在访问网站时需要执行 DNS 查询。复杂页面在开始加载前需要执行多次 DNS 查询。计算机每天可能会执行上千次查询。”
如果 Chrome 和 Firefox 都不能满足需求,可以考虑选用为低速连接优化的浏览器 Opera 并打开 Opera Turbo 模式,该功能可以利用 Opera 的服务器压缩页面及页面内的资源。Opera 使用 Google 的 WebP 图像格式节约流量,同时能展现更优质的画面。Opera Turbo 的平均压缩率可达约 60%。Android、Symbian 及 Windows Mobile 平台的 Opera Mobile 应用也提供了 Turbo 模式,另外 Opera Mini 应用提供了更高的压缩率(高达 90%)。Opera Mini 支持大多数手机,包括纯功能手机和 iPhone。
这几天去XDA闲逛,发现Z大又回来了顺便还给我们带来了一个N大的惊喜。。。这个脚本可以增强WIFI的信号。。。其实我早就发现有这篇文章了,但是一开始没弄明白这个脚本是怎么运行的。。。用Z大给的命令iwconfig总是提示 file NOT FOUND,这让我很郁闷。。。后来才发现这个iwconfig系统不是自带的,需要下载Z大提供的那个文件才能运行。。。囧一个。。。
Hi, I noticed that our wifi driver can be controlled via iwconfig to increase TX power. It’s not too impressive change (from default 14dbm to max 15dbm), but still it’s a ~25% transmission power increase considering miliwatts (25mW->32mW)
Please remember it will slightly improve your wifi connection, but also increase the power consumption!
Google 好几天之前发布了Android4.0 也就是冰淇淋三明治(Ice Cream Sandwich 简称 ICS)!最近Z大回归了XDA,给我们带来了这个最初版本的ICS。。。
不多废话,ROM信息如下。。。
[KERNEL] 内核
– ol’ good 2.6.29-SEMC 官方的2.6.29内核
– fixed touchscreen driver (now backward-compatibile with Gingerbread) 修复了触摸驱动
[ROM]
– partially based on drewis release (thanks!) – currently I don’t have access to PC that could handle compilation of the whole thing 一个致谢的话 不解释。。。
If someone could compile clean es209ra build and upload it would be awesome.
[WORKING] 可用的
– it boots 能启动(偷笑。。。)
– radio, calls, txt (sms) 信号 电话 短信
– audio partially working (in-call is fine, playing mp3/ringtones leads to WLOD) 可以打电话,但是铃声响起或者播放MP3会导致WLOD。。。(White LED of death,就是白色LED灯然后死机。。。)
– bluetooth, GPS seem to work 蓝牙 GPS 貌似可以用。。。
– wifi almost working (“can’t find wlan0 device”) WIFI 几乎可以用了。。。(也就是还不能用。。。)
– mobile data (it gets IP but disconects afterwards, needs investiagtion) 移动网络可用。。。(能得到IP地址但是会自动断开连接。。。)
[NOT WORKING] 不能用的。。。
– most of the stuff does not work 几乎没什么能用的。。。
– quite unstable 不很适合日常使用。。。

用邮箱备份VPS的数据 超简易教程
本文共被喵星人侦察过18,251次。。。最近入了一个VPS玩儿,虽然没有证据表明这个服务商不靠谱,可是数据无价啊。。。所以自己备份还是很有必要的。原来都用的cPanel的虚拟主机,也有一个cPanel自动备份的脚本,一直用着也挺方便的。但是现在用的VPS,所有的东西都要自己动手。别和我说买个cPanel授权,没那么多闲钱。。。况且我还是很喜欢自己动手的。
上网上Google了好半天,找到的脚本基本上都是备份到FTP服务器的。本来我都打算就这样了,结果突然看见一个可以把文件备份到邮箱的脚本,突然想起QQ邮箱还有500多G的空间没有用,而且应该比我的FTP空间要稳定,最重要的是这个应该不会经常性的丢失数据也不用担心空间会过期哈。于是我马上拿下来脚本试了下,结果却发现不能用。。。这让我着实郁闷啊,难道就要浪费了这大好的免费备份空间么?OH当然不是,我决定自己动手稍微改造下这玩意儿~于是乎就有了成果~~
好了废话不多说,接下来就是脚本和使用方法。。。
首先你要有自己的VPS(这是废话)。。。我的是CENTOS 5.8 32BIT,别的么,应该也可以把?除了安装MUTT的时候不大一样以外,脚本什么的应该都是通用的。。。这个脚本会自动吧过大的文件分割成20M一个的小文件,这个大小可以自己改。。。不过不建议太大,因为要通过邮箱发送。。。
华丽的分割线。。。以下教程正文。。。
#后面标注的,蓝色的内容都是注释哦~ 有注释的行可以自己修改,别的最好就别动了呢~~如果你用VI命令在VPS上面直接创建脚本文件,请吧所有的中文注释去掉。。。当然你也可以在本地用Uedit之类的软件编辑好再上传到V。。。不要用记事本,否则脚本是不能运行的。。。因为Windows和Linux的换行符不一样~~阅读全文。。。
