Some model predictive control using my matrix/math library.

Spectroscopic Characterization of Interstellar Object 3I/ATLAS: Water Ice in the Coma We present optical and near-infrared spectroscopy of the interstellar object 3I/ATLAS, obtained with Gemini-S/GMOS and NASA IRTF/SpeX on 2025 July 5 and July 14. The optical spectrum shows a red slope...

Today on the #arXiv:

Yang et al. 2025, "Spectroscopic Characterization of Interstellar Object #3I/ATLAS: Water Ice in the Coma" - arxiv.org/abs/2507.14916

#3I is putting out water ice along with organic and silicate dust.

As expected for a comet.

Ukraine has continously asked for 11-20 Patriot batteries. Here's what kind of coverage you can get with 11. Ukraine has 6~ batteries already, the remaining 5 would cost something like (barring missiles) $1.7-2B. A Patriot batteries goes for $300-400M (export/local costs are the same).

Bridge Colby has his head too far up his ass to understand this, even when China says it aloud.

It is imperative Russia be defeated swiftly and overwhelmingly so that our resources can be prioritized to China. We cannot afford a two front Cold War in both Europe and Asia.

UPDATE on our new interstellar friend #A11pl3Z:
Citizen scientist Sam Deen has found earlier observations of from June 25-28, from the ATLAS telescope!

Now with 6 days' worth of data, the eccentricity of A11pl3Z's trajectory is narrowed down to e=10.4 ± 1.1!
... that's undoubtedly interstellar.

Let there be light:

YouTube video by Sen. Elissa Slotkin Slotkin delivers speech on her Economic War Plan

As a CIA officer and Pentagon official by training, I believe that the single, greatest security threat to the United States is the shrinking middle class here at home.

Today, I laid out my Economic War Plan.

Wielding power is no small task.

Casual find when thrifting, has performance, guidance laws, and more.

6th gen, 6th gen, 6th gen

good luck dawg

It is is the 10th century muscovites are strategically being stricken from improvised aerial munitions. It is the 21st century, muscovites are being strategically stricken from improvised aerial munitions.

I find more CUDA tutorials in Chinese than I do in English.

Passed the vibe test 😤

Hey, it all works out in the end.

I haven't profiled my CUDA code yet, but it takes about the same amount of time to run 100 simulations as it does for 1. Cooking here...

6DOF state space dynamics for a satellite. Getting the back propagation right was tough. Now this is more tough...

For better or for worse I have discovered steady state error in Model Predictive Control.

Today we are going learn about Light Exo-Atmospheric Projectile's first flight test. So what is LEAP? LEAP was a program aimed at developing extremely lightweight and small KKVs. The program first spawned from an SDI effort develop a light kill vehicle for ground or space based hyper-velocity guns.

Rep HASC/SASC $150B Defense Supplemental came out a few nights ago. For the Naval end we got:
$4.2B for naval infrastructure stuff (construction, workforce, stuff of that sort)
1 Extra VA Boat in FY27
2 Extra DDG-51s
$1.8B for LSM not sure how many this covers.
1 LPD-17 (LPD-36)
1 LHA (LHA-11)

Oh Sunnyvale

Model predictive control in CUDA has really stretched my patience with coding.
