I’d first like to begin by saying I’ve written about this topic several times already. But while those were basically artistic impressions, this is an outright essay on the mild disquiet I feel every day while embedded in this society, and what probably causes it. I’m warning you right now that it’s exceedingly long… about twelve pages going by word-count alone. You’ve been warned.
I just installed Android Gingerbread (2.3) on my HTC Droid Eris. To understand the significance of this little achievement, we need to examine the wonderful world of smartphones, and why the market insists on doing a half-assed job.
The Eris was released November 6th, 2009. In the phone world, especially now that the smartphone market is heating up, this is somewhat ancient. It’s second-generation in a fifth and sixth generation world. It will never “officially” have anything higher than Android Eclaire (2.1). I’ve already been running Froyo (2.2) for months. It fixed a ton of bugs plaguing the official release, and improved the overall experience drastically.
Ah, query hints. For all those times when the database isn’t doing what you want, they’re a useful tool for forcing the query optimizer to perform your bidding. But in this case, not only is the road to Hell paved with good intentions, it’s paved with a frictionless slide directly into a wood chipper that empties handily into an active volcano. With query hints, be careful what you wish for, because—to the detriment of all you hold dear—you just might get it.
Ok, so I’ve already corrected gaudy and horrible behavior part and parcel with default PostgreSQL installs, but what about that… other open-source SQL database? Is it wrong too? Sure is!
My fake system still has 8GB of RAM, but we’ll be using more of it for a MySQL install. Why? Because MySQL’s planner makes different assumptions about memory allocation than PostgreSQL. Remember sysctl.conf? Put this in there:
I just finished reading Daniel Suarez’s Freedom (TM) in about three days. This is much more a statement of the novel’s quality than my own somewhat glacial reading pace.
There’s a lot in here I really love. Mr. Suarez has clearly done his research, even listing many of his sources, along with the universities and labs inventing the technology he brought to life. Back again are the AutoM8’s, the Razorbacks, and the rest of Loki’s arsenal. Back are the HUD glasses, the enhanced reality, and all the other disruptive technologies held down by corporate interests. And Suarez repeatedly puts them to excellent use.
