Glasnost:帮你看看电信或者网通有没有限制你的BT下载

一些网络服务提供商(ISP)对用户使用BT下载工具进行速率限制(rate limit),或者干脆屏蔽(比如Comcast曾经做的事情)。但是作为用户来讲,除非有专业的网络知识,要不很难抓住ISP的证据。

马克斯普朗克软件系统研究院(The Max Planck Institute for Software Systems)做了这样一个网站,这是一个测试,它在你的电脑和这个网站的系统之间,制造了一种类似BT传输的情况,来帮助大家查看ISP到底有没有限制你使用BT工具。

这个在线测试分为4分钟的简单版和7分钟的完整版。不过这个测试也有局限,它主要能够测试ISP是否采用了某种技术,以造成下面这些屏蔽或者限制:

  • 屏蔽所有BT流量
  • 屏蔽所有知名BT端口的流量(Throttling all traffic at well-known BitTorrent ports)
  • 仅屏蔽知名BT端口的BT流量(Throttling BitTorrent traffic only at well-known BitTorrent ports)

关于这个测试的更详细的解释在这里。需要注意的是,一些ISP仅仅当BT流量超过一定限度时才会加以限制,但是这个测试不能觉察到这种情况。这个测试很繁忙,我还没有用上,不过已经测试的8个中国用户都没有遇到受限制的情况。每个BT流量受限制的用户,在地图上显示出来就是一个红点,见上图,红点以美国为最多。大地图和各国用户的测试结果在这里

Check out if your ISP block your Bittorrent 

Certain ISPs have been shown to rate limit or block BitTorrent traffic sent by their customers. While there are multiple reports of this on the web, only a few ISPs have admitted that they manipulate BitTorrent traffic. And, to date, it is hard for users without networking expertise to gain evidence about the behavior of their ISP.

This test suite creates a BitTorrent-like transfer between your machine and our server, and determines whether or not your ISP is limiting such traffic. This is a first step towards making traffic manipulation by ISPs more transparent to their customers.  Read more.

小技俩:观看“限制级”的youtube视频

你有没有遇到过这种情况?明明搜索到了一段youtube视频,访问的时候却被告知在你的国家不能观看?像下图这样:

或者遇到这种情况?这段视频可能会招致不适或有用户举报,需要你登录或者注册后再观看,像下图这样:

这个小伎俩可以帮助大家看到,不用管什么国家限制,也不用登陆。只需把标准的youtube地址:http://www.youtube.com/watch?v=VIDEOID 换成:http://www.youtube.com/v/VIDEOID就可以了。

比如这段麦当娜的音乐视频只能在美国观看,点击下面这段链接会被告知不能观看:http://www.youtube.com/watch?v=I9ciR9qR1dU

Watch Restricted YouTube Videos

(via googleoperatingsystem) I’ve noticed that an increasing number of YouTube videos are restricted to a limited number of countries, probably because the company that uploaded them doesn’t have global distribution rights or because it wants to use different marketing strategies in other countries. Even if YouTube says that “this video is not available in your country”, you can actually see it using a very simple trick. Read more.

50G免费超大网络硬盘空间,快来拿

还挂着Beta标志的ADrive做了一件出位的事,免费提供50G网络硬盘空间!单个文件限制在2G以内。每个人只限注册一个帐号,注册时有点麻烦,特别是密码要区分大小写,要字母和数字结合。这也是防止恶意注册的一种方法。

ADrive的界面做的很干净,上下都有广告,这大概也是它的唯一收入来源。在网页内上传文件就可以了,不用再下载软件。不过要注意的是,上载的窗口是在Java平台上运行的,所以请确定你的电脑上安装了。还有一件需要注意的事,就是文件上传时,整个窗口就不能动了,也就是说在同一窗口中的其他标签页暂时不可用。下图是上传时的情况。

adrive-upload-1

将近40M的文件,上传了大概10分钟,速度还可以。上传后的文件可以选择分享(share),这时会生成一个文件链接,可以发邮件给朋友。

Live SkyDrive见鬼去吧。

Storage newcomer ADrive offering up 50GB for free

(via webware) I’m big on places to store a lot of files, and Web storage newcomer ADrive seems up to the challenge. The host serves up a whopping 50GB of storage for free, with the only bandwidth limitations being in the size of the files you can upload, which are capped at a reasonable 2GB. Read more.

5G!最大附件上传,AOL提供

无论是哪一款的邮箱,都会对附件的大小作出限制,大小一般不会超过20M,这不得不说是一个遗憾,于是出现了YousenditMailbigfile等临时存储、发送附件的替代品,但是即使这样,也还是存在附件大小限制的问题,免费服务一般不超过100M。

AOL似乎要解决这个问题了,它拥有一个出色的邮件服务Aol mail,还有一个免费用户也能获得5G存储空间的在线存储服务Xdrive。Aol要把两项服务结合起来,当你发送的附件超过16M时,它会自动把文件上传到Xdrive里(这需要你有一个Xdrive帐号),你的收件人会在自己的信箱里看到这个附件的链接,并可以点击这个链接下载文件。见下图。

另外,你也可以在Xdrive里设置把aol mail中含有的附件都自动保存到Xdrive上来。

遗憾的是,我第一次想粘帖1个adobe reader.exe,第二次想粘帖1个20M的音频文件,但是两次都没有成功上传到Xdrive,也许是这项服务刚刚开始、还不完善的缘故吧。

看来,围绕附件展开的邮箱大战又要开始了,下一个参展者该是google吧。

Send 5GB attachment via Aol mail+Aol Xdrive

Whatever mail you use, it has attachment size limited, so YousenditMailbigfile hit the nitch to provide large attachment sending service, but they have  size limited too, usually can’t be above 100MB  for the free account user.

Now we have chance to pull the limit up to 5G. This is a new service provided by Aol. Aol has a mail cilent Aol mail and an online storage service Xdrive. Now Aol integrate the two service to allow mail user to send an attachment up to 5G.When the attachment size is above 16M, it will automatically upload to your Xdrive account(of course you need sign up one).There will be a clickable url in the mail,your recipient clicks on it to download the attachment file.

I tried twice,the first time is an adobe reader.exe, another time is an audio file, but they both failed to uploader to Xdrive. Maybe the service is just open and not stable yet.
