Using twitter can sometimes feel like driving downtown, screaming what you want to say out the window, and hoping someone hears you. There might be tens of thousands of people downtown, but your message will only be heard by a few. Because of this, your best bet is to repeat your message as often as possible.

Twitter is free and if you want to reach as many people as possible, it’s another great tool for getting your message out there. But sending tweets on a scheduled basis can be a pain. There are client programs available which allow you to schedule your tweets (Hootsuite is one I have used in the past). You can load your tweets in the morning, and have the application tweet for you all day long. But you still have to load the application with your tweets—one by one.

A friend of mine asked me if there was a way to send the same 200 tweets over and over again, spaced out …

The other day I was discussing new features of MySQL 5.7 with a Percona Support customer.

Here’s a list of some MySQL 5.7 key features.

Replication Enhancements:

• One of the top features in MySQL 5.7 is multi-source replication. With multi-source replication you can point multiple master server’s to slave so limitation of slave having only one master is lift off. There is nice blog post written by my colleague on multi-source replication you will find useful.
