META: The backlog's gone, and then some

I've burned through all the backlog I built up. Worse yet, I'm beginning to lose faith in my ability to do nightly blogging. I'm going to give it another hard try, though...

I think part of it is that I got too ambitious: tried to do a bunch of serious, large-scale writing. For now, I think I'll limit myself to about 200 words per entry, so that I can keep the workload manageable. This may mean the occasional 15-part series. Whatever.

The Birthday Paradox Explained

I don't think the Birthday Paradox is that complicated to understand...

First, let's get away from the math for a bit. What if there are 367 people (curse you, Feb 29) in a room? What then is the probability that two of them have the same birthday? Why, it's guaranteed that two do! The "pigeonhole principle" says that if you keep picking unique birthdays for folks in the room, you will run out of unique birthdays before you run out of folks.

Introduction to network trust establishment [Part 1]

There seems to be a lot of confusion outside the core computer security community about what the goals and methods of computer and network trust and security are. This blog entry is a non-professional's attempt to solve some of these problems. It is inevitably going to be incomplete, since I'm busy, and contain mistakes, since this isn't my top specialization. Suggestions for improvement are appreciated...

My day was full

Started with breakfast at Original Pancake House with a friend at 8:30 AM (in the morning!), then met with an open source partner for a couple of hours, then played Abstract Interpretation for a couple of hours with students...

Mitnick, Kerckhoff, and Open Source

The web-news-o-sphere (/., digg, reddit, etc.) is all abuzz today with the news that the infamous Kevin Mitnick has declared open source programs to be less secure than proprietary programs. Actually, his actual thesis is quite a bit more nuanced than that, but folks can hardly be blamed for wanting a sound bite...

Issues for digital artifact photo archiving [Part 3]

In parts 1 and 2 of this series, I took a look at some basic issues of digital imaging of historical artifacts. In this part, I develop a brief worksheet for inventory reporting for artifact photo collections...

Issues for digital artifact photo archiving [Part 2]

In Part 1 of this series, I discussed the issue of "resolution" of digital photographs of historical artifacts. In this second part, I continue with discussions of color, of image formats, and of image sources...

Oops

I've gone a lot of years since I broke a piano. I broke my piano tonight...

Jamey's comic list and Comic Alert!

My student and friend Jamey Sharp is a long-time intense webcomics afficionado. I got sucked in, as I so often do...

Issues for digital artifact photo archiving [Part 1]

I'm becoming involved in a historical artifact photography project using digital images. As such, I need to develop some materials to use in describing collections of digital photos of artifacts. Here's my first cut. I'm trying an experiment here by breaking this into a multi-part series. I originally intended two parts, but it has gotten longer than this...
