High-Entropy Alloy 2 months ago

Paliney® 6 is an age-hardenable palladium silver-based alloy ideally suited for demanding low current sliding electrical contact applications

Depending on how you convert synapse count to parameters, the brain also has something like a thousand trillion parameters. In that light it's pretty darn surprising that an artificial neural network can produce anything like coherent text.

Fun trivia (well, perhaps not fun) in the second paragraph: "the Long Duration Exposure Facility (LDEF), which was retrieved in 1990 after spending 68 months in LEO"

Long exposure, 68 months, right. But it was only supposed to be in orbit for 11! Challenger being destroyed on reentry made a mess of things.

https://en.wikipedia.org/wiki/Long_Duration_Exposure_Facilit...

It was placed in low Earth orbit by Space Shuttle Challenger in April 1984. [...] At LDEF's launch, retrieval was scheduled for March 19, 1985, eleven months after deployment.[4] Schedules slipped, postponing the retrieval mission first to 1986, then indefinitely due to the Challenger disaster. After 5.7 years its orbit had decayed to about 175 nautical miles (324 km) and it was likely to burn up on reentry in a little over a month.[6][9]: 15

From the author's writeup:

the final pre-trained model came out to about 340 million parameters, and had a final validation bpb of 0.973. The pretraining process took about five hours on-chip, and cost maybe $35. I had my pretrained model, trained in 6496 steps. Things were proceeding swiftly, and cheaply!

GPT-3 had 175,000 million parameters. The smallest of the Gemma 4 models released today clock in at 5,000 million parameters, and I would bet that Google trained them for more than five hours. Just too small and not trained for enough time. A fun art project but not a functional LLM.

Note for the confused: Ecombi achieves this by heating the bricks to dramatically higher temperatures using conventional resistive heating elements, thereby storing more energy, even though the specific heat capacity of any ceramic material is dramatically inferior to that of water.

But, as a result, Ecombi has a much lower system efficiency than a heat pump, since it's essentially just a space heater pointed at a rock. It only makes sense for jurisdictions with time-of-day variable pricing of electricity, and trades off simplicity and low initial purchase price for lifetime cost.

The drag coefficient was the headline: 12% better than our design target.

Is the drag much better than a regular cubesat? It doesn't look tremendously aerodynamic. From the description I was kind of expecting a design that minimized frontal area.

Additional surface treatments will improve drag coefficient further.

Is surface drag that much of a contributor at orbital velocity?

Ask one of the hundreds of vending machine companies in the NYC area where they put them, I suppose. https://www.google.com/maps/search/vending+machine/@40.69452...

The only people who care about SSO are large enterprises. Coincidentally, large enterprises also are the only customers that make SAAS profitable. Every other plan is part of the sales funnel to the big enterprise contracts.

I built a meter around a SCD30 six years ago. The self-calibration routine was not very good, for two reasons.

1) It had an unrealistically low default level, something like 380 ppm. The atmospheric concentration keeps going up! The linked pdf says "The automatic selfcalibration algorithm assumes that the sensor is exposed to the atmospheric CO2 concentration of 400 ppm at least once per week." Atmospheric CO2 definitely is not 400 ppm anymore.

2) As far as I could tell it made no effort to choose a local minima. In a regularly ventilated space, if it decided to "calibrate" when a door was closed, it could abruptly declare 600 ppm to be 380. I just hard coded an offset value and disabled ASC.

For my sins, I have recently been called upon to cold boot and then provision a few dozen Samsung tablets by hand. The "laggy Lagdroid piece of lagshit" pasta has been repeated a lot. I swear to God it just ignores ten percent of touch events if it's doing anything in the background.

Also a pg essay from 2010: https://www.paulgraham.com/yahoo.html

By 1998, Yahoo was the beneficiary of a de facto Ponzi scheme. Investors were excited about the Internet. One reason they were excited was Yahoo's revenue growth. So they invested in new Internet startups. The startups then used the money to buy ads on Yahoo to get traffic. Which caused yet more revenue growth for Yahoo, and further convinced investors the Internet was worth investing in. When I realized this one day, sitting in my cubicle, I jumped up like Archimedes in his bathtub, except instead of "Eureka!" I was shouting "Sell!"

This Monday, I moderated a panel in San Francisco with engineers and ML leads from Uber, WisdomAI, EvenUp, and Datastrato. The event, Beyond the Prompt, drew 600+ registrants, mostly founders, engineers, and early AI product builders.

We weren’t there to rehash prompt engineering tips.

We talked about context engineering, inference stack design, and what it takes to scale agentic systems inside enterprise environments. If “prompting” is the tip of the iceberg, this panel dove into the cold, complex mass underneath: context selection, semantic layers, memory orchestration, governance, and multi-model routing.

I bet those four people love that the moderator took a couple notes and then asked ChatGPT to write a blog post.

As always, the number one tell of LLM output, besides the tone, is that by default it will never include links in the body of the post.

Same thing down on the production floor. Each program (737, 767, etc) has its own part number series. I'm sure there has to be some parts commonality, somewhere, with the same part getting two different numbers printed on it at the factory, but I saw no hint of it happening.

Fun fact: the two big Puget Sound factories (Everett and Renton) number their hand tools differently. It's true. A socket wrench will be EVT12345 or whatever, and the same tool in Renton will be inventoried differently.

The two factories have very different cultures. Renton does two planes a week, Everett does one plane a month. There was much grumbling during the webinars and retrainings after the Door Plug Incident that all this was being inflicted on us because of the cowboys down in Renton and their maniacal obsession with production rate, something which is not quite so much a focus at Everett.

I am surprised that open circuit voltage is specified at 25°C and increases dramatically as the temperature goes down. Seems backwards! I'm looking at the Ecoflow spec sheet right now and fair enough, it's got the open circuit voltage and then the Temperature Coefficient of Open Circuit Voltage (-0.35%/°C) right next to it.

Great, guys, how about you go ahead and multiply those two numbers for me, since you're the ones writing the fucking spec sheet? It's like if car battery manufacturers only specified a cranking amps number, and told you to figure out cold cranking amps yourself.
