Kill Math
The power to understand and predict the quantities of the world should not be restricted to those with a freakish knack for manipulating abstract symbols.

MySQL Text vs. Varchar Performance
Starting with MySQL 5.0.3, the maximum field length for VARCHAR fields was increased from 255 characters to 65,535 characters. This is good news, as VARCHAR fields, as opposed to TEXT fields, are stored in-row for the MyISAM storage engine (InnoDB has different characteristics). TEXT and BLOB fields are not stored…

Every day I learn something new… and stupid.
Hey kids, did you know that JavaScript doesn't have integers? That's right! All JavaScript numbers (either primitive numbers, or the Number object, and don't even get me started on how stupid it is that there is even a distinction between the two) are actually double floats! Now, in any Lisp-derived language, you…

Why you get ideas in the shower

Ridiculous Things To Do With CSS3 Box Shadows
Box-shadow is a pretty powerful property in modern browsers. With just six little values, you can make some really neat stuff. How much neat stuff, you ask? To find out, I set a little time aside each day to play with it. The result is 39 ridiculous little experiments that, due to whatever issues, can only be viewed…

Schneier: The Dishonest Minority: Security and its Role in Modern Society
Three months ago, I announced that I was writing a book on why security exists in human societies. This is basically the book’s thesis statement: All complex systems contain parasites. In any system of cooperative behavior, an uncooperative strategy will be effective—and the system will tolerate the uncooperatives—as…

Visualizing Time with the Infinity Hour Chart
This is another experiment in visualizing 24-hour cyclical data. My last post explored a method of linear representation (the Double Time Bar Chart). Linear representations have problems when it comes to showing the cyclical nature of time data (ie there is no start or end of a 24 hour cycle). Inspiration When trying…

Twitter and Facebook Both Quietly Kill RSS
Last year I shared how Twitter was moving more and more towards a closed, less-standards oriented model of sharing content as they upgraded their design to bring more people to the Twitter.com website. At that time, they removed the prominent RSS icons and made it only possible to access an RSS feed for an individual…

How To: Spend your investors’ money
I’ve invested in two startups and advise, officially and unofficially, a dozen or so other startups. Recently, a company that I’m involved with, attachments.me , raised $500,000 from Foundry Group . Since their raise, the two cofounders, Ben and Jesse, have been on a tear adding features, solidifying the…

Leaving Google
After seven years at Google, I'm leaving. Cue the inevitable 'what's wrong with you?' Before I get to the gripes, though, there are a few popular narratives I want to push back on: that Google has gone evil, that the good engineers are all defecting to Facebook, that 20% time was always a myth. Part one of three. The…

There's more to HTML escaping than &, <, >, and "
This was exaggeration for effect—there aren’t many cases where a simple XSS injection could actually empty a bank account—but I wanted to make a point.
