Posted on January 4, 2012 by M@

Synopsis This is rather old code, but saved my bacon more than once. Runs under Apache with Mod_Perl, and “merges” any number of filesystems. You’ll see the @docroots array that takes a list of “document roots”. These all need correct … Continue reading →

Posted on June 16, 2011 by M@

Dear MongoDB, I would like to use the positional operators you have for updates, ala ‘user.$.name’, in the field selectors for queries, ala find({“user.name”: “Matt”},{“user.$.address”}) such that I can see only the fields of that sub-document/sub-object in my return data … Continue reading →

A Perl Thread-Pool

Posted on February 24, 2011 by M@

UPDATED: 9/5/2013 to use better Thread::Queue::dequeue_timed in lieu of sleep. I’ve been doing a lot of large-system coding with Perl ithreads lately.  This thread model has been scaling very well on very high-throughput operations in conjunction with well-placed yield() calls … Continue reading →

Disposable Appliance Computing

Posted on September 24, 2009 by M@

[NOTE: This essay was commissioned by a client in February 2007. It’s the first in a series of old-yet-relevant position-papers whose exclusivity has expired, that I’m editing and posting] The hosted systems industry has turned another critical point. Several years … Continue reading →
