First 1080p video from Canon’s new 5D MkII – Amazing!
+0 Vote Up -0Vote Down


My father and I got our 5D MkIIs on Friday and we could hardly wait for the batteries to charge. He took his to SF to test its vaunted low-light performance and posted this 60-second 1080p clip (along with other resolutions) on his SmugMug site: Click to watch it auto-sized for your monitor or check out the full 1080p resolution (caution – *high* bandwidth! UPDATE: Apologies if you tried to watch 1080p on Windows earlier. My bug made it look terrible. Try again, please?).

Here’s his story:

“I had seen Vincent Laforet’s amazing short film, but only in 720p. I knew what an amazing photographer he is and wondered how close an everyman like me could come to

MySQL and Zmanda -- start to understand it
Employee +0 Vote Up -0Vote Down

I'm trying to learn more about Zmanda and MySQL.  It's just ones of those topics that is on my list of things to Google.  At this point, I know that Zmanda can do backup and recovery for MySQL, but that is about it. I'd really like to get a better grasp of the technology and how it benefits a MySQL user.  Interestingly enough, over the past week or so, I've found a few mentions of Zmanda in my inbox that might speed this learning process along.  So, I thought that I would share them with those people who find themselves in the same situation.

Nostalgia isn't what it used to be

My parents had found a box of old stuff which they delivered to me and I went through yesterday. For instance, did you know that I appeared on a photo of Kellogs Frosties (with Tony the Tiger) in 1995! We have several of those boxes still saved, empty of course. No, I'm not a celebrity. I was in the audience of a hockey game in Lillehammer Olympics which they used on their boxes in 1995. All the more memorable then, since 1995 is still the one and only year that Finland won the World Championships!

    [5.1 UCC] A series of articles on MySQL™ version 5.1
    +0 Vote Up -0Vote Down

    Today (August 1st 2008) I started write a series of articles to be referenced in my MySQL™ 5.1 Use Case Report that I will submit later this month to the Community Team for the MySQL™ 5.1 Use Case Competition.

    I guess UC Reports should contain real world use of MySQL™ 5.1. So if I am not mistaken you can submit a Report on partitioning, for instance, if you are using v. 5.1 because you need partitioning and you can include in your Report the reason you needed partitioning and a description of your development and deployment environment.

    Now, I am not using Partitioning (or Events or Plugins) because I *need* partitioning in my production system for a specific reason. I am a developer so I developed software on those features ;-). So

    Andrii Nikiti’s son Needs Our Help
    +0 Vote Up -0Vote Down

    (Reposted from Zack Urlocker’s blog)

    Andrii Nikitin, one of the MySQL support engineers located in Ukraine, has asked for help from MySQLers and so I’m sharing this information to the community at large. Andrii’s son Ivan, who is 2 1/2, is in need of a bone marrow transplant operation. This will require going to a clinic in Europe that will not be covered by regular insurance. So Andrii has aksed to see if we could help raise funds. The cost is expected to be 150,000 - 250,000 EUROS. A huge amount for an engineer from Ukraine to cover. But a small amount by many people could make a big difference.

    Many MySQLers have kicked in to help out, but more is needed. Ivan’s health has taken a turn for the worse recently and the issue is now quite pressing. Even a small donation could mean the difference between life and death for Ivan.

    mylvmbackup 0.9 has been released
    Employee +0 Vote Up -0Vote Down

    I am happy to announce that a new version (0.9) of mylvmbackup has been released. This is the first release since the source code has been moved from Subversion to Bazaar and is now hosted on Launchpad.net. I would like to thank Robin H. Johnson and Patrick Hahn for providing the patches that contributed to this new release!

    mylvmbackup is a tool for quickly creating backups of MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, makes an LVM snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup

    I'm Joining Craigslist in July

    I wasn't really looking for a new job a few months ago when I received an email from Eric Scheide (see Team Bios), the CTO at craigslist. He mentioned that they were looking for someone with MySQL experience and asked if I knew anyone. This sort of thing happens all the time.

    But this time it was different. Over the course of about three seconds, something clicked in my little brain and I realized that craigslist is a pretty unique combination of things: a small company with a solid financial base, a great service that I use myself, a focused groups of people who really care about doing things well, and an

    Great conference yesterday at “La Sapienza” University in Rome with Marten Mickos and the Italian Team of Sun | MySQL.

    I’ve just returned in Triest, my hometown, after 8 hours :( train ride.

    Slides should be available the next week, here.

    Marten, thank you for coming, I hope to see you in Italy once again!

    I will be in Rome on May 30 to attend the meeting with Marten Mickos.
    Giuseppe has posted a translation of the official announcement of the event, here.

    I will be there as a member of the Community and as CTO of HoneySoftware (an Italian ISV, MySQL® Enterprise Ready Partner).

    I am wondering if there will be also a meeting in the morning with customers (as Giuseppe posted) or not: the official agenda starts only at 4:30 pm.

    See you there!

    New Responsibilities
    +0 Vote Up -0Vote Down
    During my university days when I was working towards a dual degree in Accounting and CIS, I co-founded a small managed hosting company which I ran for four years along with two other co-founders. Then I started a consulting company and eventually moved into online publishing. Things changed and after nearly nine years of being self employed, I took over the very challenging responsibility of single handedly managing and scaling databases of a top 50 site (in 2006). It was definitely not an easy journey and I feel ecstatic to have helped my employer handle 6x growth and rise to being a top 13 site (using same Alexa algorithm).

    While I enjoy working with MySQL, Solaris and technology a lot, I really missed being part of business side. Those of you who know me outside my database role, know how much I crave problem solving related to day to day business

    So, I mentioned before that I found out about index_merge at the MySQL Conference. I was wondering why I had not heard more about it since it came out in 5.0.3. When talking with some MySQL people about it, I received mixed results. So, I decided to kind of run my own tests on some data and see what I could figure out.

    I apologize for Wordpress' bad output. =(

    I created a table with 5 million rows. Early tests with MySQL's Harrison Fisk (HarrisonF) over my shoulder with small data sets showed MySQL would optimize out the indexes in favor of table scans. I wanted to avoid that. This is my table schema:
