Starship - SpaceX

Isn't Deep Seek the hot new LLM?

It's more complicated than that. nVidia stock took a hit, but has recovered.

Elon Musk started OpenAI with Sam Altman and others. While he stepped back due to conflict of interest with Tesla's AI work, Sam Altman left yCombinator to focus on OpenAI, and they adopted a ‘capped-profit’ strategy.

So OpenAI was started as Open Source but devolved into a for profit; while Deep Seek promotes Open Source with a CCP filter.

Basically, Deep Seek is a proof of concept (lower resolution reduces computation cost) that will be adopted/coopted by all others going forward.

edit:
I found this article on The Register where IT is pushing back against the Deep Seek phenomenon. www.theregister.com: The hidden cost of compromise

As the technology industry continues its shift towards AI dominance, an important schism is opening up that threatens to impact scientific progress, along with important humanitarian endeavors such as disaster response.
....
While this industry-wide shift has accelerated AI advances, it's creating an unintended consequence: the erosion of high-precision computing, which is vital for important applications such as climate modeling, aerospace engineering, and pharmaceutical research.

Possible launch day today.

From SpaceX website-

"Distinct vehicle and pad criteria must be met prior to the return and catch of the Super Heavy booster, requiring healthy systems on the booster and tower and a final manual command from the mission’s Flight Director. If this command is not sent prior to the completion of the boostback burn, or if automated health checks show unacceptable conditions with Super Heavy or the tower, the booster will default to a trajectory for a soft splashdown in the Gulf of America."

It looks like a repeat.

I missed watching it in real time, but now I'm caught up. Yup, same failure mode it seems, which is good because consistent problems are easier to troubleshoot and correct.

The shame is that the engines only needed to survive another 20 seconds and the rest of the mission could have been flown. I wonder if the 1min static fire contributed to something wearing out? Perhaps if the static fire was not performed, it might have survived the mission?

Any time you light an engine you have limited possible outcomes: works up to commanded power (which may or may not be up to over 100% rated), works partially, doesn't work, spontaneously disassembles. You can't model it, and testing it on a pad is different than free testing under load. Sounds to me like they didn't get the actual fault fixed, must be counter intuitive or too much pressure to launch ( they drilled ventilation holes for chrissakes) I think too much gotta launch it, now!!! Is the failure, or at least as it looks from here. Daddy has too many fires going and lost focus and had a tantrum. Wouldn't be the first time*. Good thing he doesn't use solids because at those power levels, there would be no launch site available to find. Makes the dinosaur extinction event.

Putting it all on the moneybags guy disrespects (for better or worse) the person achually in charge, Gwynn Shotwell, president and chief operating officer of SpaceX.
