Essential Computer Science Lore Watching a class of undergrad CS students work on a midterm exam for a C programming course was a good motivator to start putting together this list of “Essential CS Lore”. leune.org/2026/03/11/CS-…

@mattjay Any day and every day :-) We should touch base some day soon. Lots of good things happening here!

@leune Hope you’re well! Great to hear you’re still pumping out security nerds on Long Island.

Got an intern at Tesla in the Bay Area looking for help figuring out their first steps into infosec. Does anyone nearby want to meet them for coffee and point them in the right direction?

@mattjay Thank you, on their behalf!

hey @leune - one of your students reached out to me. Trying to help him out.

Willing to give @leune@infosec.exchange on Mastodon a shot. Hoping for a much better signal-to-noise ratio over there

So. In line with continuous contingency planning. What will the infosec to the Twitterverse be?

Sunset on the Flagpole Lawn at ⁦@AdelphiU⁩

@awpiii @kriggins No words.

We lost another of our own this week. Kevin Riggins @kriggins. hamiltonsfuneralhome.com/services/servi…

@wendynather The Dutch legacy to the Western world :-)

Press roundtable and keynote slides done — it’s #StroopwafelTime

Not bad. 50W on 17m

A solar flare index of 252 is probably one of the higher ones I have seen in a long time. Let's see what this does to propagation conditions!

@mattjay School year just started. I'm there 5 days a week! Let me know when, and I'll try to arrange it!

@leune Went to an old Adelphi friend's wedding! Would love to catch up as well.

I just *knew* in my body that something bad was going to happen to my house while I was in NYC this weekend. - I walked in on eggshells expecting it to be broken into, or flooded, something. All was fine, but man I'm broken.

@CoachChrisDelli Thanks coach! Stay safe!

Just heard Thunder, so Summer Camp is canceled for tonight. See you Thursday!

@myrcurial @jwgoerlich @hackerradio Resubscribed :-)

That moment when you're working on a loaner laptop that has been locked down for "security", which makes it practically unusable, and it takes 30s to bypass if you know what you're doing. Security that hamstrings device users is ineffective. Maybe consult the security team first?

6m was on fire today with sporadic E. Watching that fade out on the WSJTX waterfall is amazing. Took less than 5 minutes from 2000km+ signals to barely a local peep.

The 6m amateur radio band is weird. VHF but 1000+ mi without issues on one day. S9 noise floor the next. Completely dead the following. #hamradio

@wimremes Good list. Maybe one more would be 'transparent and response service provider'. I really don't like sales folks going all 'proprietary' on me when I try to do a risk assessment

What are the key properties of a "secure" application? Either from the perspective of the manufacturer or from the buyer/customer?

And with that.... my last grades for the semester have been posted!
