I can't believe we're doing this again, but...we're doing this again. Another day of record-shattering Match heat across interior West & Central U.S., w/countless March (& even some April) monthly records broken. Some locations are even breaking monthly records set...last week.

During production of Finding Nemo, we started using Linux boxes in addition to SGIs.
Why?

3D painting software we wrote for laying out coral was written in C++ using templates, and the debug info was too large for IRIX, but was debuggable on Linux.

Was this a 32 bit vs. 64 bit issue?

No.

IRIX reserved half the address space for the kernel, while Linux only did a quarter.

So on Linux, we had 3GB, and the symbols fit.

It was a 32 bit show, both machines had 4GB max.

Plenty for Finding Nemo.

In a Trump administration with an already stunning track record of deep incompetence, this takes the cake.

Trump administration underestimated Iran war’s impact on Strait of Hormuz

The Pentagon and National Security Council significantly underestimated Iran’s willingness to close the Strait of Hormuz in response to US military strikes while planning the ongoing operation, according to multiple sources familiar with the matter.

I look forward to proper spin training in a Pitts coming up some weekend soon!

My back might be broken, but the surgeon doesn't seem to think that would mean no aerobatics (my primary reason for having switched from the rv-10 to the rv-8). If I need surgery, it would mean no phase one aerobatics, but they can always be added afterwards by going back into phase one once everything heals.

The scrap value of an RV-8 is around $1000, just a data point.

I've never had to agree that I'm not building a ballistic missile before, but with that done I'm the proud owner of some nice carbon fiber tubing for an aerobatic sight device for the RV-8.

A friend asked how Signal added post-quantum cryptography to the Double Ratchet while keeping it backwards compatible. That rabbit hole of math and code led me to build two interactive visualizations covering all algorithm layers of NIST FIPS 203 ML-KEM (Kyber) and the HQC backup algorithm that form the new PQC standards:

Plus a breakdown of Signal's upgrade to the PQC-resistant Triple Ratchet with downgrade attack protection:
