I have implemented multi-factor authentication systems and have given public presentations on the topic, but I didn't jump to that as the first association for the acronym MFA. Guess I need to work harder on my geek cred!

Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics gave a great talk at the CfA on this topic a few years back. He created GCAT, a database that attempts to track all artificial space objects. https://planet4589

I find this article to be excellent description of what makes a great REPL and what makes REPL development powerful. Coding in Clojure with Emacs CIDER - with it's integrated code editor and REPL - is the most fun I've ever had wi

I want to like repl.it, and it's obviously great for many use cases, but compared to, say, CIDER for Clojure, it's like typing with cement gloves. Even if it weren't so slow, there are some features I'd need before consi

Drive the (26’ motorhome) RV. Somewhat limiting in cities, but the rest of the time it’s so much easier not towing. And there are tricks for dealing with cities, like parking on the edge and biking in. Or finding RV friendly lots using goog

I’ve been to the Stata Center dozens of times for meetings, conferences, receptions, or just passing through. I like the exterior, but inside it’s horrible. It’s cavernous, bad acoustics, drab and utilitarian, geometrically weird and theref

Here's an implementation in Clojure that scores hands and selects a winner. It handles low vs high ace in straights. https://gist.github.com/mchampine/dca965226148dfd19d5e4d7f3d... Most of it was done for a weekly

I use the waking up app also. It's pretty nice. There's a introductory course on mediation, a daily meditation, and lots of theory and interview podcasts. Harris takes you through lots of variants of 10 minute meditations, focusin

It was a natural experiment in what happens without police when the city is in the midst of an extreme wave of crime and violent protest, and one of the protests turns into a riot while the police were on strike. The idea that this incident

Yes, I remember there was a OO programming style/discipline layered on C that was floating around in the mid 80's and I tried it out. (just found out there's a whole book about it - https://book.huihoo.com/pd

I like the sentiment, but there's several factors here, including inherent "agility" and of course luck. I never broke a bone as a kid, and not only spent half my youth outdoors but was a daredevil. Summer: Tree climbing, as

Nice post, good for a certain degree of "dissecting". I assumed however that we'd be going all the way down to the bytes. I spent quite a long time with "A Layman's Guide to a Subset of ASN.1, BER, and DER" as

Me too. I was bored with 2 decades of C/C++/Java and didn’t like programming any more. Dabbled with Ruby, Python, Groovy and enjoyed them. Discovered Scheme, SICP, and Clojure and never looked back. Beat my head against not having
