Team Sphinx to the MySQL User Conference!
+1 Vote Up -0Vote Down
MySQL is the world’s most popular open source database. Sphinx allows MySQL users to search text (and more) at scale, without choking-out their favorite database. It’s a match made in the big data heavens. So, it shouldn’t be a surprise that this year, like many years before, we’ll be heading to the Percona Live MySQL [...]

People frequently ask us questions along these lines, so we decided another blog post on the subject would be worthwhile. Check it out! Introduction This [...]

From MySQL Fulltext Search to Sphinx
+0 Vote Up -0Vote Down
MySQL fulltext search (FTS) is old and well known. It has a simple setup and requires only small changes for querying. For many people it’s more than enough to provide fulltext search. So, here’s the question: why add a new variable – Sphinx – into the system when the database already has the basic functionality? [...]

Until 2.1.1-beta the functions exposed in custom rankers for handling relevancy based on term frequency and Inverse Document Frequency (IDF) did not take field or document lengths into account. In 2.1.1-beta, Sphinx includes functions that take relevance ranking to the next level. New IDF functions mysql> SELECT * FROM myindex WHERE MATCH(‘less_common more_common’) OPTION RANKER= [...]

Mastering The Linux Shell – Bash Shortcuts Explained (Now With Cheat Sheets)
+0 Vote Up -0Vote Down

During my day-to-day activities, I use the Bash shell a lot. My #1 policy is to optimize the most frequently used activities as much as possible, so I’ve compiled these handy bash shortcuts and hints (tested in SecureCRT on Windows and Konsole on Linux). The article only touches on the default bash mode – emacs, not vi. If you haven’t specifically assigned your shell mode to vi (set –o vi), you’re almost certainly using the emacs mode. Learn these and your shell productivity will skyrocket, I guarantee it.

Update #1: In response to a few people saying this list is too short and “[he] could've added something to it, to atleast make it look longer” (quote from one of

MySQL Slave Lag (Delay) Explained And 7 Ways To Battle It
+0 Vote Up -0Vote Down

Slave delay can be a nightmare. I battle it every day and know plenty of people who curse the serialization problem of replication. For those who are not familiar with it, replication on MySQL slaves runs commands in series – one by one, while the master may run them in parallel. This fact usually causes bottlenecks. Consider these 2 examples:

  • Between 1 and 100 UPDATE queries are constantly running on the master in parallel. If the slave IO is only fast enough to handle 50 of them without lagging, as soon as 51 start running, the slaves starts to lag.
  • A more common problem is when one query takes an hour to run (let's say, it's an UPDATE with a big WHERE clause that doesn't use an index). In this case, the query runs on the master for an

Best MySQL Server Under $10K?
+0 Vote Up -0Vote Down

I want to get opinions from outside of my daily circle of people on the best server hardware to use for MySQL. I remember from the conference somebody (Pipes?) mentioning a particular Dell server with multiple disk RAID10 that could supposedly be had for about $6k but I completely misplaced the model number (Frank, did you get my email?).

I know that a multi-disk RAID array with a bunch of fast disks (15k RPM?) is probably the most important method of improving performance, followed by the amount of RAM, so I'm trying to find the best combination/balance of the two. However, server prices on the Internet range so

Barracuda Tries to Gobble-Up SourceFire
+0 Vote Up -0Vote Down

Over the last few years there has been a lot of fanfare around open source companies and their liquidation events. Most of the news has been around Sun’s billion dollar acquisition of MySQL or the Citrix acquisition of Xen and even Yahoo’s acquisition of Zimbra. In contrast there was little attention paid to the SourceFire. Actually if you ask most open source users about SourceFire they would probably answer “SourceWho?” If you ask open source users if they have heard of ClamAV or Snort they probably would be able to tell you that they are the leading open source

Microsoft Ex-Pats Developing Open Source Software Outside of Redmond
+0 Vote Up -0Vote Down

It seems that open source maven, Matt Asay along with well-known Microsoft blogger Mary Jo Foley have come to the conclusion that Microsoft doesn’t need open source. Asay contends that Microsoft’s open source activity has more to do with regulators than best practices and user collaboration.

Microsoft’s open-source charade is not about customers. It’s about regulators. Until Microsoft can convince U.S. and European regulators that its market power is not as bad as it once was, the company will need to hide behind expressions of openness.

Hence, Microsoft “opens” up its protocols (i.e., lets everyone read but not touch…without forking

The Little ?3? of Open Source Systems Management?
+0 Vote Up -0Vote Down

Last year open source analyst Michael Coté of Redmonk coined the term Little Four to describe four up-and-coming open source management vendors and as a foil to the Big Four of systems management.

In the open source space, the 4 names that come up each time ? usually from people I?m talking with even before I say anything ? are: Zenoss, Hyperic, GroundWorks, and

Future Open Source Superstars
+0 Vote Up -0Vote Down

This week’s Open Source Business Conference was a strange meeting of Enterprise IT users, venture capitalists, and free software entrepreneurs. The opening keynote was delivered by Red Hat’s freshly minted CEO Jim Whitehurst who gave a very modest speech noting that while Red Hat has been a leading open source company they have not necessarily been an open source leader. Whitehurst’s presentation lacked anything especially insightful or noteworthy and he has the advantage of being the new guy so he’s off the hook for anything that might have happened before he took the job.

What is apparent Red Hat’s no

Open Source Valuations, Competition, Downloads, and Profitability
+0 Vote Up -0Vote Down

And on goes my fascination with open source companies and their valuations…

I was reading Stephen O’Grady’s commentary on open source companies and their valuations prompted by the recent acquisition of MySQL by Sun for $1 billion. He quotes Jeff Gould who logically questions whether Sun can make the acquisition pay-off.

Stephen also quotes a piece from Knowledge@Wharton on the myth of market share.

It is a common practice of many companies to focus their attention on grabbing market share from their competitors. But such efforts
