How to Use SHA256 to verify downloaded files
When you download an ISO image, especially from many unknown seeds on the BitTorrent network, we recommend that you verify the integrity of the downloaded image.
For the Ubuntu release, Canonical provides several verification files (such as MD5SUM, SHA1SUMS, and SHA256SUMS) for verification ). In this example, we use SHA256SUMS.
First, download the following two files.
$ Wget http://releases.ubuntu.com/
stable (3 times my current book has been stuck), but it has a special feature Opera Turbo (compress the webpage so that the computer can access the Internet normally when the network bandwidth is insufficient, it can also save traffic) I like it very much.

As many people may know, due to the counterattack by the Motion Picture Association of America and other organizations, the BT download website suprnova.org closed all BT resources on its own, but then published an exciting message: the "exeem" software will be released to replace BitTorrent downloads.According to suprnova, exeem is a new file sharing software that combines the advantages of Kazaa and BT.

This is usually unacceptable for Systems (because it means that a large amount of cache is invalid or data needs to be transferred ). So how to design a load balancing policy to minimize the number of affected requests?The consistent hashing algorithm is used in memcached, key-Value Store, BitTorrent DHT, and LVS. It can be said that consistent hashi

Multipart download uses the multipart download feature of aria2 to speed up object download, which is particularly useful for downloading large objects. To use the multipart download function of aria2, you must specify the s option in the command. For example:aria2c -s 2 http://www.mirror.tw/pub/ubuntu/releases/jaunty/ubuntu-9.04-desktop-i386.isoThis will use two connections to download the file. The parameter value after S is between 1 ~ 5, you can choose according to the actual situation.
