A magnifying glass concentrates light on a small spot. As many mischevious kids can tell you, a magnifying glass as small as a square inch in size can collect enough light to start a fire. A little Googling will tell you that the Sun is 400,000 times brighter than the Moon, so all we need is a 400,000-square-inch…
Register-level simulator of the Sinclair Scientific calculator
This is a loose transcript (or long paraphrasing?) of a presentation given at ConnectDev'16, a conference organized by Genetec in which I was invited to speak.

Commit messages matter. Here's how to write them well.
There's lots of innovation going on in security - we're inundated with a steady stream of new stuff and it all sounds like it works just great. Every couple of months I'm invited to a new computer security conference, or I'm asked to write a foreword for a new computer security book. And, thanks to the fact that it's…
Some time ago, I wrote a blog post about how there’s more to a pointer than meets the eye. One key point I was trying to make is that just because two pointers point to the same address...
Since SpaceFM is entering the GTK3 realm (SpaceFM can now be built on anything from GTK 2.18 “I won’t give up my lenny!” thru GTK 3.6.x), I’m starting to hear more feedback …
Introducing the Dice-O-Matic mark II, now generating the die rolls on GamesByEmail.com. It is a 7 foot tall, 104 pound, dice-eating monster, capable of generating 1.3 million rolls a day.
Random numbers are critical for cryptography: for encryption keys, random authentication challenges, initialization vectors, nonces, key-agreement schemes, generating prime numbers and so on. Break the random-number generator, and most of the time you break the entire security system. Which is why you should worry…

Editor's Note 1 : I have no editor. Editor’s Note 2 : I would like to assure new subscribers to this blog that most my posts are not as long as this one. Or as long as my previous one . My long break from posting here means that this piece is a collection of what would’ve normally been a series

This is going to be a two-part post—one on why machine intelligence is something we should be afraid of, and one on what we should do about it. If you’re already afraid of machine intelligence,...
An emoji flipbook presentation by Alex Komoroske about how dysfunctional organizational dyanmics arise even when individuals are well-behaved
On a NIST-sponsored hash function mailing list, Jesse Walker (from Intel; also a member of the Skein team) did some back-of-the-envelope calculations to estimate how long it will be before we see a practical collision attack against SHA-1. I’m reprinting his analysis here, so it reaches a broader audience. According…
In this document, I describe what is, in my humble but correct opinion, the best known algorithm for threading messages (that is, grouping messages together in parent/child relationships based on which messages are replies to which others.) This is the threading algorithm that was used in Netscape Mail and News 2.0…
AI folklore tells a story about a neural network trained to detect tanks which instead learned to detect time of day; investigating, this probably never happened.
The text in these files is the unedited original manuscript. M-K has fine copy editors, who have fixed all the minor typos, spelling, and grammar errors in the printed book, but if you come across factual errors I'd still appreciate help getting all the details of linking and loading as complete and correct as…
Last month, Ethan Heilman, Tadge Dryja, Madars Virza, and I took a look at IOTA, currently the 8th largest cryptocurrency with a $1.9B…
The sustainability pages are essentially done, although I plan to improve them and respond to inadequacies people find. Having done my best to show that material progress is sustainable, I can justifiably turn my attention to the future and present ideas about what progress people will want and what can be achieved…
The classic beginner's mistake in Argentina is to neglect the first steak of the day. You will be tempted to just peck at it or even skip it altogether, rationalizing that you need to save yourself for the much larger steak later that night. But this is a false economy, like refusing to drink water in the early parts…
