UPDATE: The Special Operations Forces Rapid Acquisition Consortium for Emerging Requirements (SOF RACER) Industry Training Registration is now OPEN. You heard about the launch just a few weeks ago, now it is time to act. U.S. Special Operations Command (USSOCOM) and GovSignals, are hosting the first virtual training session to show industry partners how to leverage this break-through acquisition tool. SOF RACER is free to use for defense contractors or non-traditional commercial companies who are looking for a fast track to deliver cutting-edge technology and SOF-peculiar capabilities to USSOCOM. If you are looking to join us in the fight to bring rapid capability for SOF across every domain, this virtual session is for you. Details are below. Sign up now.
📅 Date: 20 August (virtual session)
🕒Time options (select one):
0900–1000 ET / 0600–0700 PT

met a girl at a bar in sf last week. she's building autonomous drone mapping for construction sites, raising her pre-seed, and strips on weekends to fund it. didn't even flinch when she said it. just asked her what flight controller she's using. this city is actually unhinged.
The ADHD dream career is being a professional "idea generator" who sits in a room for 1 hour, solves everyone else's complex workflow bottlenecks with chaotic lateral thinking, and then vanishes into thin air before anyone asks for a written report.
Not many people know this, but SpaceX has already launched two American commercial spacecraft that successfully landed on the Moon
First, Falcon 9 launched Intuitive Machines’ Odysseus
Seven days later, Odysseus touched down near the lunar south pole, becoming the first commercial spacecraft to successfully soft-land on the Moon and returning America to the lunar surface for the first time since Apollo 17 in 1972
Then Falcon 9 launched Firefly Aerospace’s Blue Ghost
Blue Ghost landed successfully, delivered 10 NASA science and technology instruments, and operated across an entire lunar day before continuing several hours into the lunar night
Think about what SpaceX has restored to the United States:
• Falcon 9 and Dragon returned human spaceflight to American soil
• Then Falcon 9 helped return American spacecraft to the Moon
Not once but Twice
SpaceX restored capabilities America had lost, reopened the road to orbit and became the bridge carrying the country back to the Moon
Now Starship is being built to carry the people, cargo, habitats and equipment needed to establish a permanent human presence there
Falcon 9 brought America back to the Moon
Starship is being built to help humanity stay there
Topology optimization? Of course you thought it would solve your problems. You fed the solver a single static load case and watched it chug on von Mises stress like it was Gatorade, all while completely ignoring principal stresses and actual mechanical properties.
Let me guess -- you just finished the SolidWorks Simulation or Autodesk Fusion generative-design marketing deck (or maybe the Ansys webinar), and now you think organic lattices are the future because the pretty red-to-blue plot said so.
You’re going to believe that right up until the first prototype hits the machine shop and they call you, asking why the flanges are thinner than the paper your college degree -- the one you Chegged your way through -- was printed on. Then the part buckles laterally under a moment that wasn’t even in your load case, crumples, and suddenly it’s your problem.
While you’re dealing with that, you’ll finally notice that the “optimized” geometry has internal corners that act as stress risers, which the solver didn’t catch because the mesh was too coarse. Whoops. Now your impossible-to-reach toolpaths are forcing the shop to either use EDM or scrap the whole batch because you gave zero thought to how the part would actually be fixtured, inspected, or survive any real manufacturing process. The QC guys aren’t even turning the CMMs on; they’re just laughing the drawings back to the office.
Then you’ll finally open Hibbeler’s Mechanics of Materials for real this time -- not just to regurgitate the von Mises formula -- and you’ll read the sections on lateral-torsional buckling and realize that the critical moment drops with the cube of the flange thickness and the square of the unbraced length. Your solver maximized both penalties while smiling at you. It never checked geometric nonlinearity. It never asked whether the material was ductile enough for the equivalent-stress assumption to hold. It never cared.
After that, you’ll crack open Timoshenko or the AISC specs, stare at the LTB equations, and it will hit you: topology optimization isn’t failing because the algorithms are bad. It’s failing because you treated a single-parameter stiffness game like it was engineering.
Anyway, Dave from a subsystem four teams away needs to move a bolt pattern over a quarter inch. Do you want to throw your CAD model away, or should I do it for you?
The riveting first hand account of Colorado Parks and Wildlife and U.S. Forest Service employees risking the Gold Mountain Fire to hike into Nate Creek and catch native, endemic Uncompahgre cutthroat and hike them out to safety away from the fire.
Uncompahgre cutthroat are incredible, genetically distinct, native fish to the headwaters of the Colorado and Gunnison Basins. If these fish had disappeared in this fire, there would be no way to replace them. This type of fish, in conservation, is known as the Nate Creek “halotype” which means they have a unique genetic fingerprint found only in the Uncompahgre cutthroat.
Electrofishing is nonlethal fish stunning device that CPW hiked into the burn zone in heavy backpacks, escorted by forest service firefighters. Trout float to the top, recover in seconds, but are easily removed brought back down to the safety of the hatchery. All in all they netted around 100 Uncompahgre cutthroats, carrying them down in 5 gallon buckets (down a steep incline in the middle of a burn zone). When conditions improve, they’ll be hiked back in. Huge thanks to CPW and the Forest Service for protecting the Uncompahgre cutthroat.
