"We inserted this furin cleavage site into a beta coronavirus from bats to help physicians treat future infections in humans"
Purdue University's IDEAS Lab built an autonomous drone that tracks runners through dense forests completely without GPS or cloud networks. By running 3D LiDAR mapping and obstacle-avoidance AI entirely on-chip, it can weave under tree canopies and predict target movement through blind spots in real time. Massive implications for next-gen search & rescue and edge AI.

Security called me at 6:12 AM today. "Patch every PHP server immediately." I asked what happened. "Two critical vulnerabilities. Remote code execution. No authentication required." Cool. How many PHP servers do we have? According to inventory: 12 According to reality: Nobody knows. We found one running WordPress. Three running old internal tools. One under someone's desk. Two inside vendor appliances. A forgotten employee directory from 2016. And a server named: PHP-OLD-DO-NOT-TOUCH Naturally, that one runs payroll exports. Then we found a PHP 5.6 box. I asked who owned it. The documentation said: BRIAN. Brian left in 2019. We called Brian. He said: "Oh wow, that's still running?" Excellent. By 8 AM, leadership joined the incident call. CEO: "Can hackers actually get in?" Security: "Potentially yes." CEO: "Without a password?" Security: "Yes." CEO: "Then why do WE need passwords?" Not the lesson. Finance asked if we could wait until the weekend to patch because downtime affects revenue. Security explained that the alternative was letting strangers execute code on our servers. Finance asked for a cost comparison. At 9:17, someone suggested temporarily taking the vulnerable websites offline. Marketing refused. "Our campaign is live." So for the next hour, the company officially decided maintaining a landing page for 20% off webinar registration was more important than preventing remote server takeover. We finally patched everything we could find. Then our scanner discovered another PHP server. Hostname: TEMP-PHP-2014 Uptime: 4,512 days. Nobody knows what it does. Nobody owns it. Nobody can shut it down. But every time we block network access, the warehouse stops printing shipping labels. Security has classified it as critical infrastructure. It is running PHP 5.4. The vulnerability has existed longer than half our employees. The emergency patch took four hours. Finding out what PHP actually runs took eleven. The internet isn't held together with code. It's held together with servers everyone is afraid to turn off.

In my Bio-Inspired AI & Optimization course, I scaffold intro to reinforcement learning with earlier content about swarm intelligence (like Ant Colony Optim.). The RL stuff frames the trails as an embodied Q(s,a) function. See 9:13 to 12:40 in video: youtu.be/DPIbp4e5kAo?si=nM7x… 1/🧵

So, I thought it was pretty cool to see this new #SwarmIntelligence article pop up on my feed this morning, from Soma et al. (2026) [including @SwarmDynamics]. They take the analogy way further than I ever did! They focus on the honey-bee waggle dance as a single RL agent. 2/🧵

💯!! "True intelligence" is not just coming up with (plausible?) solutions but being able to disseminate them clearly to those who might actually use that knowledge. As a prof once told me early in my career, if it's not disseminated, it's not science. These AI's must do better.
I would argue this is a failing of the AI systems. The ~700 math proofs in Lean are sloppy, complicated, and tangled. We really should hold our AI agents to a higher standard: they should produce work that is elegant, clean, and explainable, just as we would ask from a human genius. Incomprehensible code or incomprehensible proofs is a failure IMHO, and an indicator of sloppy work and sloppy thinking.

This real-time ocean runs entirely in your browser, from a single 61 KB HTML file. It renders FFT waves, whitecaps, sky, and sun glitter at about 260 FPS in 1440p on an RTX 5070 Ti. Claude Code wrote it from 1 prompt on raw WebGPU, with no 3D engine or libraries.

Did you hear about the kid who misspelled "impunity" in the spelling bee? They still let him win.

New widget for exploring GLMM's or warm-starting #stats coding after quick prototyping: tpavlic.github.io/topic_visu… Import your own data or use sample data sets. Try different response families/random effects. Export to #Rstats code (+MATLAB/Python). Translate classic tests to GLMM.

And if you prefer something similar that focuses on more classical parametric and non-parametric tests of means (one group, two groups, and several groups -- t tests, ANOVA's, etc.), see this "Output Analyzer" I built for my sim course. tpavlic.github.io/asu-simula…

Yes, but did they count all of the instances of "tomato sauce" in countries that don't call it "ketchup"? 🤔 Plus the surplus packets in the USA that are discarded in to-go. I'm surprised Australia 🇦🇺 didn't make the list. That said, charging for condiment probably makes a dent
The wiki page for ketchup has some amazing facts.

Why are these guys all like this. Dude, you have a tool sitting right in front of you that will enable you to explore the mathematical landscape in ways that would have been unimaginable a year ago. And you're sobbing in your Chardonnay.
Fields medallist Hugo Duminil-Copin was deeply shaken by OpenAI’s release of more than 700 AI-generated mathematical manuscripts, including work on 16 questions directly relevant to his research. “On Tuesday night, I cried, and it woke up my daughter” “They have annihilated my field of research.” lemonde.fr/sciences/article/…

Electronic tiltmeter buried in active volcano in Hawaii. Pretty sure that spike on October 9 was the earthquake in Panama.

Meh. There are shitty teachers who focus on applications, and there are shitty teachers who focus on theory. It's not the theory that's the problem. Some people are just shitty teachers. Stop blaming a whole field for the flaws of one professor (or even an intransigent youth).
When I was moving into my ML career after years in academia, I made a pragmatic decision to just focus on getting things to work, instead of learning any theory. I thought one day I might come back to fill in the gap, but at some point I realized that it was in fact largely a waste of time.

Update: Latest version can export any analysis shown in the current view to code for #MATLAB, Core&Tidy #Rstats, and #Python. Goes beyond exporting graphs. Actually provides code for doing analyses (including checking for conditions necessary to meet assumptions of those tests).
A new widget for my stochastic sim course that might be useful for more general #stats courses -- can act as a web-based replacement for basic JMP. Load data sets at top, do parametric and nonparametric one-sample, two-sample, and multi-comparisons/ANOVA. tpavlic.github.io/asu-simula…

I haven't maintained my own CV in LaTeX for a while, but I used to have a popular LaTeX CV template that I moved archived to Github some time ago. I had some extra cycles, and so I went and updated it today to support PDF/UA accessible LaTeX. See: github.com/tpavlic/latex_cv_…
