The web is nothing if not a maze of user accounts and logins. Almost everywhere you go on the web requires yet another new set of credentials. Unified login seems to elude us at the moment, so the status quo is an explosion of usernames and passwords for every user.
programming languages
Software developers do have a proclivity for puzzles. Perhaps that’s why books like To Mock a Mockingbird exist. It’s a collection of logic puzzles which is considered an introduction to lambda calculus, one of the core concepts of Lisp. Such puzzle questions are de rigueur for many programming
storage
Everyone who has ever purchased a hard drive finds out the hard way that there are two ways to define a gigabyte. When you buy a “500 Gigabyte” hard drive, the vendor defines it using the decimal powers of ten definition of the “Giga” prefix. 500 * 109 bytes = 500,000,

The multi-platform password cracker Ophcrack is incredibly fast. How fast? It can crack the password “Fgpyyih804423” in 160 seconds. Most people would consider that password fairly secure. The Microsoft password strength checker rates it “strong.” The Geekwisdom password strength meter rates it “mediocre.” Why is Ophcrack so fast? Because it
user experience
Cyrus Najmabadi* hates tabs in web browsers: Ok, I seriously don’t get tabs on Windows. Hell, I don’t get tabs on OSX either. In the latter there’s a great system called Expos, and in the former the taskbar does the job. Once I start using tabs, things
user interface design
Task-Centered User Interface Design is a 1993 book delivered in digital shareware form, and also available as a PDF. Although it’s almost fifteen years old, it’s still highly relevant – a testament to the timelessness of studying human interface design principles. It was written by Clayton Lewis and John

One of the premium features of the New York Times website is the Windows Reader. It’s free if you subscribe to home delivery of the paper, otherwise it’s $14.95 per month. One of the key attractions of the Times Reader is that it lets you read the
usability
In-N-Out Burger is a fast food institution here in California. Part of their appeal, I think, is their radically simplified menu. Instead of forcing customers to process a complex menu with a hundred choices, In-N-Out got real and pared it down to what really matters: a burger, fries, and a
hardware
I’m a big fan of dual-core systems. I think there’s a clear and substantial benefit for all computer users when there are two CPUs waiting to service requests, instead of just one. If nothing else, it lets you gracefully terminate an application that has gone haywire, consuming all
c++
Eric Lippert notes the perils of programming in C++: I often think of C++ as my own personal Pit of Despair Programming Language. Unmanaged C++ makes it so easy to fall into traps. Think buffer overruns, memory leaks, double frees, mismatch between allocator and deallocator, using freed memory, umpteen dozen
One of the hot new features introduced with Windows 95 was the Windows Registry. The Windows Registry offered a centralized database-like location to store application and system settings. No more plain text .INI files splattered all over your system. Instead, issue a few easy API calls and your application settings
ergonomics
I spend almost every waking moment in front of a computer. I’m what you might call an indoor enthusiast. I’ve been lucky not to experience any kind of computer-related injury due to my prolonged use of computers, but it is a very real professional risk. I get some
