Great little post on how to avoid disaster at home when charging:

Model Y is the most efficient electric SUV in the US

Greater efficiency = lower charging costs = saving you $$$

It’s Cybercab Bonanza day at Giga Texas! Fresh off the posting yesterday showing Cybercabs autonomously driving out of the production like exit point and taking the ~2 mile trip to the W EOL and @Tesla being granted a Level 4 Autonomous @Roxotabw service license in Texas, today we see a lot of Cybercabs on the move, with the hatch open showing the wheel covers prepped for shipping, ~ a dozen lined up at the factory exit point and much more!

Check out this Cybercab action today!

You want to try again?

I interview dozens/hundreds of new grads, nearly every day of the year. These are people with a well-formatted resume and a Bachelor's Degree in Engineering from well-regarded US universities and a GPA above 3.6. The majority cannot engineer, cannot function independently, cannot answer basic technical questions. We have watered down standards and inflated grades to the point that a bright, enthusiastic student spending four years in school sends almost no signal at all.

What does? Hard evidence of actually building stuff. There is no substitute for actually doing the thing.

Elon Musk:

“I don't think most people understand just how quickly machine intelligence is advancing. 

It's much faster than almost anyone realizes, even within Silicon Valley and certainly outside Silicon Valley. People really have no idea.”

🟥 W toku procesu wycieka coraz więcej szczegółów. Zabójca, Vickrum Digwa, zadzwonił na policje, a nie na pogotowie i skłamał, że to Henry go zaatakował, był pijany, obraził go rasistowsko i strącił mu turban.
Policja Hampshire przyjechała (trzy policjantki) i natychmiast zakuli Henry’ego w kajdanki, mimo że leżał w kałuży krwi z ranami kłutymi klatki piersiowej i nóg. Wielokrotnie powtarzał: „I’ve been stabbed” („Zostałem dźgnięty”), „I can’t breathe” („Nie mogę oddychać”). Na nagraniu z kamery osobistej słychać głos policjanta: „I don’t think you have, mate” („Nie sądzę, koleś”).
Policjant, który zakuł Henry’ego w kajdanki, śmiał się, gdy ten powiedział, że został dźgnięty. Potem wleczono go po żwirze i trzymano skutego, gdy się wykrwawiał. Dopiero gdy stracił przytomność, funkcjonariusze zdjęli kajdanki i zaczęli reanimację. Henry zmarł na miejscu.
Ponadto policja zabrała telefon Henry’ego i jego taty i przeczytała wszystkie wiadomości w poszukiwaniu rasistowskich komentarzy lub żartów.
Teraz policja z Hampshire wydała publiczne przeprosiny: „Przepraszamy, że Henry został zakuty i aresztowany w momencie, gdy tracił przytomność. Zostaliśmy okłamani przez sprawcę…” Mimo to ani sad, ani policja nie ujawniły dotąd nagrań z kamer.
Trwa dochodzenie IOPC (niezależny organ ds. skarg na policję). Wielu domaga się dymisji funkcjonariuszy, którzy byli na miejscu. Trzy policjantki podobno odeszły ze służby (niepotwierdzone).

Having Grok Build sub-agents to iterate several ideas for me on data loading, batching, inference, and writing results to files for dense datasets before I went to sleep.

It gave me a nice summary of trade-offs and validation in the morning.

The same idea can be extended to almost anything as long as gradient descent and stochastic sampling apply.

Looking forward to how you utilize the sub-agents.

[xAI @xai]

grok-build-0.1 is now available via the xAI API in public beta.

This is the same model that powers the Grok Build CLI and excels at agentic coding.

Priced at $1/m input and $2/m output, it’s extremely cost effective, intelligent, and fast.

Tip on Grok Build + Grok 4.3 VLM

One of my critical tasks is to keep Grok VLM in the loop. Throwing a default system prompt usually yields poor results due to lack of context.

Here is how to scale:

- Curate a small but diverse evaluation set that can be rapidly iterated on.

- Enter the prompt: “Make a plan to design and execute a task that a) takes input per entry from: <input>, b) generates output per entry to: <output>, c) the ground truth of output: <ground truth>. Launch sub-agents to iterate on strategy to optimize recall and precision against ground truth until both metrics reach <threshold>.”

Done. Watch your research agents do the work.

Lee Kuan Yew abolished trial by jury in Singapore after determining that it was too easy for defence lawyers to appeal to racial and religious biases of juries in multicultural Singapore.

He writes in his memoirs how as a young lawyer he was able to get three clients acquitted who he was sure did commit murder. LKY writes that he "worked on the weaknesses of the jury -- their biases, their prejudices, their reluctance really to find four Muslims guilty of killing in cold blood or in a heat of great passion, religious passion, an RAF officer, his wife and child."

He writes "The judge was thoroughly disgusted. I went home feeling quite sick because I knew I'd discharged my duty as required of me, but I knew I had done wrong.”

Study after study shows that in multi ethnic societies, there is significant in-group bias on juries.

“I’ll kill your whole f–king family. Your whole f–king family is dead. Your children, your wife, all dead."

A left-wing activist in Newark was caught on camera shouting those words at an unmasked ICE officer as protests outside the Delaney ICE facility turned chaotic.

Acting AG Todd Blanche is now firing back, promising that the "disgusting" activist will be caught and charged, emphasizing that threatening a federal officer and their family is a federal crime.

“That is disgusting … and we see his face and I promise you we will find him, and when we find him, we will arrest him."
