Blitzted: The Third Reich as a Society on Drugs
So my copy of Norman Ohler’s splendidly-titled Blitzed showed up. This could have been a really disappointing book – in the acknowledgments, Ohler mentions a Berlin DJ friend who told him Nazis took masses of drugs, and I can well imagine going from that beginning to lurid Hitler Channel kitsch. But Ohler has achieved…

So You Want to Be a Hero?
Rule #1 is “The Player Must have Fun.” It’s trivially easy for a game designer to “defeat” players. We have all the tools and all the power. The trick is to play on the same side as the players, to tell the story together, and to make them the stars.

Why the Apple II ProDOS 2.4 Release Is the OS News of the Year

The Space Shuttle Discovery is up in orbit, safely docked to the International Space Station, and for the next five days, astronauts will be busy figuring out whether it's safe for them to come home.

Sierra Gets Creative
Coming out of Sierra On-Line’s 1984 near-death experience , Ken Williams made a prognostication from which he would never waver: that the real future of home as well as business computing lay with the open, widely cloned hardware architecture of IBM’s computers, running Microsoft’s operating systems. He therefore…

Dinosaur and Lisp
Dinosaur is old enough, as well as Lisp, they may like each other. When I am talking about dinosaur here, I mean the dinosaur hiding in Google Chrome, it shows up when "There is no Internet connection".

More, less, and a story of typical Unix fossilization

Mainframes as a lifestyle choice
I started working at IBM last year on mainframe compilers with the goal of making mainframes feel a little more modern. Hence, a lot of my time is spent in z/OS . The interface I use to z/OS is Unix System Services (USS, a.k.a. the command line), but if I were up for bucking the whole moderm thing, I could break out…

Learning from Ada
This is a cautionary tale. One of youth and a lesson I eventually learned but still often don’t heed. About how sometimes, the tool that is easiest to get started with isn’t the tool that will make your job the easiest.

The Secret Button
There's a secret button hidden in Windows 7. At least, it's a secret to some people. Many modern users won't know about it, whereas some like me have used it every day for over 25 years.

The Raspberry Pi Has Revolutionized Emulation
Every geek goes through a phase where they discover emulation. It’s practically a rite of passage. I think I spent most of my childhood – and a large part of my life as a young adult – desperately wishing I was in a video game arcade. When I finally obtained my
