This is a public service article encouraging all of us to back up our data (which more and more is our lives). I sketch some methods and resources for doing this.
As more of our life becomes digital (work, finances, passwords, pictures, contacts,dairies,videos and email) we must be more diligent in backing up our data. If your hard drive fails at work you might lose some spreadsheets (and you might not lose anything if your IT department is on their toes) if you computer fails at home you lose your wedding album. Your hard disk will fail and try to take all of your data (life) with it- it is a matter of when not a matter of if. You want this to be an inconvenience, not a disaster. Become expert at backing up and take the time to help others.

I recently had the pleasure of finding a copy of the manual for my favorite calculator. I know it is incredibly nerdy to have a favorite calculator (and even more nerdy to read the manual), but it really got me thinking. Continue reading The Joy of Calculation
There is plenty of blame to go around from the current global financial crisis. But, I would like to point out that it is not “all the quants’ fault.” We are all now, unfortunately, sitting in the middle of a high quality (and extremely expensive) lesson in financial mathematics. I would hate for some of the truly important points to be lost to paying too much attention to some of the shiny details.

Some time ago I subscribed to The Database Column because it would be fun to see what these incredible people wanted to discuss. We owe much of our current database technology to Professor Stonebraker and Vertica sounds like an incredible product. And I definitely want to continue to subscribe.
However, the reading experience is marred by some flaw in their RSS system that keeps marking the article “MapReduce: A major step backwards” as a new article. This causes the article to appear in my RSS reader every few weeks as “new.” This wouldn’t bother me too much except that the article runs so counter to experience that it is itself offensive.

I don’t really know what the right answer to the $700 Billion Dollar Bailout Question is (I have not read the bill, and I wonder if the bill really describes what would happen). But the whole situation does remind me of a related question: is it really the end of the world if the “credit markets freeze?” It is a disaster if the equity markets tank for a period of longer than a year or so (prevents people from retiring and so on)- but I am not sure if all of the consequences we are being told really follow.

I recently had one of those “practitioner’s epiphanies” that I
really feel captures the core of the issue and quickly explains a lot
My current definition is:
Mathematics is the minimal environment to preserve ideas.

Information week describes the current “Yahoo/Google deal” as being one that would “allow Yahoo to place Google ads on its site and collect the revenue.” But in reality it is a deal that will allow Google to sell Yahoo the rope to hang itself. To the theorist’s eye the deal looks like a doomsday machine designed along the lines of a simple game called a “stag hunt.” Continue reading YAYGDA (Yet Another Yahoo Google Deal Article)

Anand Rajaraman recently wrote a very thought-provoking entry on his Datawocky blog. He asks “Is Search Advertising a Giffen Good?” As he explains a Giffen Good is a sort of economic doomsday machine that some segment of consumers are forced to buy more of an inferior good as the price of the inferior good goes up. His article is well written are really invites one to think about the issue. Anand’s question made me thing about a number of issues (which I will outline here) and I will leave off with a question of my own.

The other day’s blog post and a recent Andrew Binstock interview of Donald Knuth made me think more about how the ACM is really not serving the interests of computer science. Continue reading I know, I am the one being a jerk
“Sorting Used in Anger” (A rambling glimpse into the mind of a theorist)
Author: John Mount
The other day I had a bit of time to kill before an appointment. Luck was with me: there was a nearby bookstore and I was able to pass some of the time skimming through a book called “Beautiful Code.” Everything started out fun and nostalgic. The book title reminded me of “The Art of Computer Programming” (a book that probably did as much through the grace of its title as it did through its incredible contents to attract minds into theoretical computer science). One of the chapters of “Beautiful Code” was by Jon Bentley (a hero of sharp reasoning and clever coding) and as I flipped to the chapter my day was ruined. There it was: Quicksort an algorithm that I have a long love and hate relationship with.
