Help me pick a new feed reader

I’ve been using Google Reader since it was created. I really love the *idea* of Google Reader. I like that scrolling through the posts marks them as read. I like that you can toggle between list and expanded views of the posts. I like that you can search within a feed or across all feeds (though selecting multiple specific feeds would be great).

All of that said, I’d like to explore other avenues, because I don’t like that there’s, like, zero flexibility in how the Google Reader interface is configured. My problem starts with large fonts…

I use relatively large fonts. If you increase the font twice up from the default size in firefox on a mac (using the cmd-+ keystroke, twice), and you have more than just a couple of feeds, you wind up with this really horrible side pane with the bottom half of it requiring a scroll bar, and the text wraps, and it just looks terrible. What makes this really REALLY REALLY …

SVN: How do you use svn command line on Windows with ssh tunneling?

If you ever used svn command line, you know it is not optimal to type in your password every time you do checkout, checkin, info, etc.  In linux world, it is very easy to setup keys to get around this.  Of course in the world of Windows it is not as easy.  Here are the steps you need to follow to get private/public keys working with your SVN under Windows using ssh tunneling.

Assumptions:  you will be connecting as user “root” to svn server located at “10.0.0.1”.  All your files will be saved at c:\ including your svn command line utility

First we will have to generate a key.  We can accomplish this by using a free utility called …

MySQL Problem and Solution Posts: r0ck.

Taming MySQL is… challenging. Especially in very large, fast-growth, ‘always-on’ environments. It’s one of those things where you seemingly can never know all there is to know about it. That’s why I really like coming across posts like this one from FreshBooks that describes a very real problem that was affecting their users, how they dealt with it, why *that* failed, and what the final fix was. Post a link to your favorite MySQL Problem and Solution post in the comments (oh yeah, and “subscribe to comments” should be working now!)

24 Hour DBT2 run on the Intel X-25M SSD

Following up on my previous post Peter asked if he could see a 24 hour run on the Intel drive…  took me a few days because I am doing some testing on a few other things, but I kicked a run off yesterday before leaving the Vegas airport…  Here ya go:

These are roughly 10 minute TPM averages.  As you can see their is a definate decline in performance the longer the drive is active.   Its realtively small% wise, only about 6% off of peak…  but the delcine is easy to spot.

What’s this mean?  It you beat the hell out of the drive over a long contious period things slow down the longer the drive is in continuous use.   Just an FYI, the drive was 78% full during these tests.

CPU Affinity for Interrupts

Thought I would throw this out here so I remember it, and it maybe useful for someone else.  During a session here at Sun’s CEC conference one of the presenter was talking about setting CPU affinity for hardware interrupts.  This made me think of our hack ( workaround ) for innodb scalability on a 16 core machine ( set the mysqld affinity to cpu’s 0-7 or 8-15 ).   In order to get the top performance out of a 16 core machine we probably want to ensure everything else goes to the cpu’s not set to be servicing mysql.   So a quick google search came up with this article on setting the affinity for IRQ’s in the linux kernel.   So with a 16 core box, I could set the affinity for Mysqld to cpu’s 8-15, while setting the affinity of the interrupts to something in the 0-7 range.
