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”.

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

[Kees Leune W2CJL @leune]

@mattjay Thank you, on their behalf!

Willing to give @[email protected] on Mastodon a shot. Hoping for a much better signal-to-noise ratio over there

[Kees Leune W2CJL @leune]

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

@awpiii @kriggins No words.

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

Not bad. 50W on 17m

[Kees Leune W2CJL @leune]

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!

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

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