I’m thinking about just making this an open source project hosted someplace like Google Code or something, because there are folks much smarter than myself who can probably do wonders with the code I’ve put together here. Loghetti takes an Apache combined format access log and a few options as arguments, throws your log lines…

Taking Virtualization to the Next Level: AppLogic
Every now and then, something comes around that is as useful as it is novel. Of course, the notion of virtualized systems isn’t new. In fact, systems running something like what we now call a “hypervisor” have existed for, literally, decades. But what about that next level of virtualization? What if you could not only…
Hadoop introductory video
This is a great talk with the head of Yahoo’s grid team that talks about the open source project Hadoop, which is an open source distributed file system and MapReduce implementation. The video is long and interspersed with Yahoo! specifics you might not care about – but keep watching, because they swing back to talking…
Sun Acquires MySQL
I’m pretty sure I’m not pleased about this, but I guess only time will tell. Maybe now my boss will let me move to PostgreSQL 😀 See the news release here Blogged with Flock
AppLogic Cheat Sheet
I’ve been using AppLogic for exactly one month today, and I’ve learned a whole heckuva lot about what it takes to build an infrastructure using the AppLogic grid operating system. One of the very first things I learned is that there is just a TON of documentation, but a very large portion of it is…
How to Build Your Own MySQL 5 Server in AppLogic
I’m building an infrastructure on a grid using AppLogic, which is a grid OS that provides both GUI and command line interfaces to build your infrastructure. I use both interfaces, depending on the task I’m trying to perform at the time. One thing I have discovered is that there are a lot of somewhat nebulous…
Holy Crap I’m Busy
I feel guilty that I’m even taking this little bit of time to post this. I’m *BUSY*. I’m simultaneously: learning how to deploy a fully-virtualized, production infrastructure on a grid using AppLogic planning and scripting the bits and pieces that need to happen to migrate an infrastructure to a grid architecture. Doing code review for…
Recovering deleted files from an svn repository
I know I’m going to forget how to do this, because I only ever need to do it once a year or something, so I’ll put it here for safe keeping: To recover a file from svn that you deleted from your local repository, it’s first necessary to get the proper name of the file,…
UNIX mtime vs. ctime
Sometimes I get questions from people about stuff that I’ve long since taken for granted. One is “what’s the difference between mtime and ctime?” The answer is simple, but I wanted to post it here in case it can help anyone. In UNIX: mtime is “modification time”, and it is the time at which the…
New Job!
I started a new job about 6 weeks ago. I’m now doing infrastructure architecture at http://gfdl.noaa.gov GFDL stands for Geophysical Fluid Dynamics Lab. It’s a NOAA site that supports atmospheric and climatology research. So in other words, the work I do supports research into things ranging from global warming to what the atmosphere on Mars…
