Adding good content to Twitter can be a pain. I can’t do it during working hours, and I don’t have much time at night. But, the more content you have, the more followers you can gain, and the more your original tweets can be seen (hopefully). I have written several posts about using the latest Perl-Twitter API – Net::Twitter::Lite::WithAPIv1_1, so you might want to check these out as well.

– Use MySQL and Perl to automatically find, follow and unfollow twitter users

– Using Perl to retrieve direct messages from Twitter, insert messages into a MySQL database and then …

A friend of mine asked me how they could automatically follow and unfollow people on Twitter. But they didn’t want to follow just anyone and everyone. He had a Twitter account which they used for recruiting in a very narrow construction industry. He wanted to find people in the same industry and follow them – hoping they would follow him back and learn about his open jobs. When I joined Twitter back in 2008, I wrote a similar program to automatically follow/unfollow users, but the Twitter API has changed quite a bit since then. So I decided to re-write the program with the latest Perl-Twitter API – Net::Twitter::Lite::WithAPIv1_1.

Before you attempt to use these scripts, you will need to register your application with twitter via apps.twitter.com, and obtain the following:

consumer_key
consumer_secret
access_token …

In two earlier posts, I gave some examples on how to use Perl to send tweets stored in a MySQL database to Twitter, and then how to automatically reply to your retweets with a “thanks”. In this post, I will show you how to automatically download your direct messages from Twitter, store the messages in a MySQL database, and then delete them.

I don’t like the way Twitter makes me read my direct messages. Granted, the majority of them are not real messages. The message is usually thanking me for following the sender, and then there is a personal website link or a link to a product they are selling. But if I want to delete a direct message, I have to …

On Tuesday  Steaphan Greene  announced that all currently-pushed changes have now been rebased onto the newly-released upstream MySQL-5.6.24.

The new branch at this point is available on github.

Our .deb and .rpm builds are available in the PSCE repo as well as being browsable here http://repo.psce.com/download/webscalesql/

Instructions for using the repo are available for Debian …

I had an enjoyable time last night at Twitter with local MySQL DBAs and developers. We had an attendee who has no experience with SQL or programming at all. She is interested in organizing her collection of recipes and had heard a rumor that MySQL was a good tool to use for this task. She indicated that her desktop runs Windows 7. I think I’m going to encourage her to turn her concept in to a community project, as she is not the first person I’ve met who wants to organize recipes!

We were hosted by Rob at Twitter, who used to work with Lisa back before she retired. He’s a member of the site reliability team and keeps the fail whale from rearing its blubbery head.

Pizza was provided by my dear friend and long-time open source buddy Gerry Narvaja with the assistance of the folks in the kitchen at Zeek’s.

We discussed new techniques in the areas of load …

Twitter’s Calvin Sun

Twitter’s Calvin Sun (@Calvinsun2012) is looking forward to the fast-approaching Percona Live MySQL Conference and Expo this April 1-4 in Santa Clara, Calif. He’ll be speaking, yes, but he’s also looking forward to learning from his peers – particularly those at Facebook. Both companies, he explained, are in the rather unique positions of unprecedented rapid growth and ever-expanding performance demands.

Calvin is a senior engineering manager at Twitter, where he manages MySQL development. Prior to that, he managed the InnoDB team at Oracle. Calvin also worked for MySQL Inc. from 2006 to 2008, managing MySQL storage engines development. He has over 15+ years of database development experience.

He said MySQL is the data storage technology behind …

The Percona Live MySQL Conference and Expo 2014 is just two months away. I’m very excited about this year’s event which continues our tradition of open technical discussions and inviting all parties to the table.

We have a great amount of technical talks from Oracle – I’m especially excited about future-focused talks shedding some light about what to expect in MySQL 5.7 and beyond. This content is best covered by developers actually designing the system and writing the code. We also have great coverage of MySQL alternatives from Percona and MariaDB. You can view the entire program here.

It is great to see well-rounded coverage of many …

Percona founder and CEO Peter Zaitsev delivers the opening keynote at Percona Live 2013 in Santa Clara, Calif.

MySQL gurus from Oracle, Facebook, Google, LinkedIn, Twitter, Yelp (and more) have submitted papers and will speak at the third annual Percona Live MySQL Conference and Expo 2014 in sunny Santa Clara, California this coming April 1-4.

If you attended last April’s Percona Live MySQL Conference and Expo – and/or last month’s Percona Live London 2013 conference – then you understand the value of learning from some of the world’s best and brightest system architects and developers. So you might want to consider registering now and take advantage of …
