A few ideas: Include multiple documents in a single <add> operations. Note: there is no advantage in trying to post a huge number of docs in a single go. I’d suggest going no further than 10 (full-size docs) to 100 (tiny docs). Ensure you are not performing <commit/> until you need to see the updated [...]

If you are unfamiliar with SSH this is ok. This is a simple explanation to get you to a command prompt on your new server or existing server. Simply download a program called “putty.exe” if you are using Windows. If you are using MAC you will need to jump in to the shell and follow [...]

Here are some ideas, how you can monitor the database performance of your MySQL installation. Monitoring is always an iterative and continuous process. You need to learn what patterns are OK for your database and what are the signs of slight problems or even dangerous situations. Below are the main items you can use to [...]

I can use tcpdump to verify that encryption is working. Here is what a plain unencrypted POP mail session looks like. This is an abbreviated example showing only the initial three-way TCP handshake. You can do this yourself by firing up tcpdump, then checking mail. Ctrl+C stops it: # tcpdump port 110 15:04:49.050227 windbag.34348 > [...]

 MySQL supports several storage engines that act as handlers for different table types. MySQL storage engines include both those that handle transaction-safe tables and those that handle non-transaction-safe tables: MyISAM manages non-transactional tables. It provides high-speed storage and retrieval, as well as fulltext searching capabilities. MyISAM is supported in all MySQL configurations, and is the default storage engine [...]

Virtual Hosting allow web servers to host more than one website on a sing machine. This is how sharing hosting works. I become pretty handy as well while develloping different web project on the same machine and allows you to access to your local repository using addresses such as http://dev.mysite.com instead of http://localhost/~myuser/myproject/ :) .

Changing this setting without a GUI will require some text editing, but that’s classic linux, right? Let’s open up the /etc/network/interfaces file. I’m going to use vi, but you can choose a different editor sudo vi /etc/network/interfaces For the primary interface, which is usually eth0, you will see these lines: auto eth0 iface eth0 inet [...]

If a user is authenticated at the proxy you cannot “log out” and re-authenticate. The user usually has to close and re-open the browser windows to be able to re-login at the proxy. A simple configuration will probably look like this: Â acl my_auth proxy_auth REQUIRED http_access allow my_auth http_access deny all But there is [...]

Short for Media Access Control address, a hardware address that uniquely identifies each node of a network.
