Re: MySQL 5.1 vs. MySQL 5.5: Floats, Doubles, and Scientific Notation
+2 Vote Up -0Vote Down

Reading Sheeri's MySQL 5.1 vs. MySQL 5.5: Floats, Doubles, and Scientific Notation, I was baffled at this change of floating point number notation.

However, I was also concerned about the final action taken: using "--ignore-columns" to avoid comparing the FLOAT/DOUBLE types.

The --float-precision option for pt-table-checksum currently only uses ROUND() so as to disregard minor rounding issues. But it can very easily extend to handle the difference in floating point notation. Consider again the problem:

    The state of MySQL client libraries
    +5 Vote Up -0Vote Down

    Those who’ve been around the MySQL world are probably aware of the much-discussed topics of GPL licensing, dual licensing, and in particular, licensing of the client libraries (also called connectors or drivers) and the FOSS exception (http://www.mysql.com/about/legal/licensing/foss-exception/) to that licensing. This is newly relevant with the announcement of a permissively-licensed MySQL-compatible client library for MariaDB.

    The difference is that this time there’s been some question about the provenance and history of the source code. Some people asked me about this. Some of them were aware of a relatively obscure detail: there’ve been permissively licensed MySQL client libraries for years, in the form of libdrizzle, a BSD-licensed library for the Drizzle fork of MySQL.

    Here are some of the thoughts that seemed to be going through

    Those of you who know me also know that I spent over six years working for MySQL HR (for another couple of years I stayed on with Sun).  I joined as employee thirty-something, so running HR meant that I was more or less involved with hiring all of the 400 or so employees who joined after me.

    Super Python: three applications involving IRC bot master, MySQL optimization, and Website stress testing.

    In my ongoing efforts to migrate my fun side projects and coding experiments from SVN to Git I’ve come across some of my favorite Python based apps – which are all available in their respective repos on BitBucket, as follows:

    IRC Bot Commander

    • What it does: it’s an IRC bot that takes commands and does your bidding on whichever remote server the bot is installed on.
    • How it does it: the bot runs on whatever server you install it on, then it connects to the IRC server and channel you configured it to connect to and it waits for you to give it commands, then it execs the commands and returns the output to your IRC chat window.

    Simple jQuery: how to validate IPv4 addresses and netmasks
    +0 Vote Up -0Vote Down

    Unfortunately jQuery doesn’t come with default form validation to check for ip-addresses or subnet masking. So without a long winded explanation here’s the code. Just include this as a separate JS file like the rest of your page’s JS.

    // 'ipv4': IPv4 Address Validator
    $.validator.addMethod('ipv4', function(value) {
        var ipv4 = /^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$/;    
        return value.match(ipv4);
    }, 'Invalid IPv4 address');
    // 'netmask': IPv4 Netmask Validator
    $.validator.addMethod('netmask', function(value) {
        var mask = /^[1-2]{1}[2,4,5,9]{1}[0,2,4,5,8]{1}\.
        return value.match(mask);
    }, 'Invalid IPv4 netmask');

    The Winter season for conferences is catching up speed.


    As I write this the DOAG conference in Germany is happening. It is one of the biggest (or the biggest?) Oracle user group conferences outside of USA. Many of my European friends in the MySQL space are talking there. As you know I have been a big fan of Galera Cluster for MySQL for over a year now, but I was perhaps a bit of an early adopter. Lo-and-behold, I was surprised to see the DOAG related press-release from SkySQL puts the creators of Galera first in their headline: Codership, SkySQL und weitere Top-Experten rund um das Thema ‘MySQL Datenbanken” in Nürnberg

    I am very excited to share that today Zmanda has combined forces with Carbonite - the best known brand in cloud backup. I want to take this opportunity to introduce you to Carbonite and tell you what this announcement means to the extended Zmanda family, including our employees, customers, resellers and partners.

    To our Partners, Employees, Customers, Friends, and Community:

    It is my unfortunate duty to inform all of you that DynamoBI is ceasing commercial operations October 31, 2012; we are immensely grateful for all the support that you all have shown our company, in so many different ways, over the past 3 years and we hope to make this shutdown as painless as possible for all involved.  We know that we are not the only people who are invested in LucidDB, so we wanted to explain our rationale for shutting down along with the implications for the entire LucidDB community (not just our customers).

    We started DynamoBI 3 years ago when we saw our most favorite open source project, LucidDB, finding limited prospects for adoption without a growth to full, commercial support which many (most!) companies need to be able to adopt open source software.  We had been
