rajnathani··on Merz: Google Cloud is sovereign enough for intelligence agencies
That’s not for business customers, let alone with sovereign cloud tier which this article might be referring to as per a sibling HN comment.
rajnathani··on Semi-transparent, colored cadmium telluride photovoltaic panels in agrivoltaics
This makes sense, as there have been quite a few VC-backed vertical farming (mostly for vegetables, as you can’t grow grains AFAIK) startups which have shut down in the recent few years.
rajnathani··on Declarative Dragging
It’s funny that you write this, as when I was at Salesforce, I picked up a nested list drag-and-drop task solo except-testing (as the “go to” UI person on the team), and it took me almost the entire release cycle (1/3rd year release schedule (but picked it up later into it)) to complete it. While it turned out good (and I remember the feature’s implementation getting praise by a senior manager at a sub-org demo meeting), that I was called into a team meeting for a “Root Cause Analysis” (paraphrasing) to discuss why the feature took so long to implement.
rajnathani··on Silicon Valley Promises AI Will Cure Disease. Drugmaker CEOs Aren't Buying It
AI integrated into a loop with wet labs, like how Anthropic is trying to do (not novel, as other companies trying this too, likely Jeff Dean’s new startup too), does seem very promising.
rajnathani··on Intel plunges 25%, triggers global chip rout on bleak outlook
They had their earnings report yesterday. Same for Intel today.
rajnathani··on The 1.5°C goal of the Paris Agreement is no longer viable
Forest fires are carbon-neutral, as trees grow back and re-capture the carbon.
rajnathani··on 3rd Yandex Cloud Data Center Was Hit
Out of curiosity, which was the 4th nation besides the US and China?
rajnathani··on Visa, Mastercard, major banks facing new litigation over 'anticompetitive' fees
> 2. Merchants should be allowed to pick and choose which cards they accept without penalty.

Isn't the case already?

rajnathani··on OpenAI annualised revenues $20B less than previously signalled
Nvidia’s revenue is more than that per quarter, the demand for AI workloads is through the roof.
rajnathani··on Replacement of petroleum based products with plant-based materials (2025)
Why is this on the front page? It just seems like a meta-analysis on biofuels.
rajnathani··on AI has no intent and no motivation
The loop is a deterministic programmatic routine, and not model weights. This is the equivalent of a killer military drone written in C++ and OpenCV. I’m not arguing that AI isn’t dangerous, but nothing in the model weights of LLMs show signs of self-preservation.
rajnathani··on AI has no intent and no motivation
Well, an amoeba just like all other living beings, maximizes self-preservation/propagation for which the article mentions as a trait which AI models do not have.
rajnathani··on If your agent commits a crime, who is responsible?
Very closely related: This is already a point of discussion for level 4/5 ADAS systems. For example, Mercedes stating that they’ll take liability for crashes related to its self-driving system.
rajnathani··on OpenRouter is joining Stripe
> Turns out even a proxy can be worth $8bn with the right business model behind it.

People said a similar thing for Cursor simply being a VSCode wrapper for when it crossed unicorn status.

rajnathani··on Turns are Better than Radians (2022)
Dumb question: For multiplying for smaller turns such as 1 arc-second (1,296,000 in 1 turn), that would floating point precision issues be a tiny slight issue (22619.4671 arc-seconds in 2pi radians), or is it just a coding convention change?
rajnathani··on Cerebras CS-4
Interestingly they’re still on the WSE-3 (5nm TSMC) wafer chip and slightly bumped up the specs there (overlocking mostly it seems), for why it’s called WSE-3 Turbo now. I think people were also expecting WSE-4, as it’s been 2 years now since WSE-3 was launched.
rajnathani··on Stenchill: 3D Printable Solder Paste Stencil Generator
For very thin stencils, I doubt plastic 3D printing or even laser-cutting plastic works, as such thin plastics would deform rather than remain flat-ish rigid like steel stencils.

Also for 3D printing solder paste, this technique is called solder jet printing. But it isn’t very popular in the industry (despite being less wasteful) due to it being slower than stencil solder printing.

rajnathani··on Kimi K3: Open Frontier Intelligence
Impressive performance (also the part about Delta Attention, which seems interesting).

Not trying to start a flamewar thread, but isn’t every Chinese LLM censored on certain major political topics? I understand that fine-tuning at least DeepSeek can remove this, but just saying.

rajnathani··on Berkshire's $397B Bet Against an Overheated Market
I would rename the title to “The Buffett Indicator shows an overvalued market”. For those curious of its definition (from the article):

> The Buffett Indicator, a ratio that measures the market cap of the entire stock market against the GDP of the United States, has hit a record of ~232%. Historically, anything above ~120% is a signal of the market being overvalued.

That being said, it’s not clear that the Buffet Indicator is fully relevant, as a lot of the US AI and AI hardware companies’ market caps which are driving the stock market valuation growth involve a significant portion of their revenue from outside the US, and thus this wouldn’t necessarily count fully to the US’s GDP (for example, tax entity workarounds for foreign obtained revenue).

rajnathani··on Apple to skip high-end M6 Mac chips in favor of AI-focused M7 line
Tangential: About 8 years ago ex-Apple chip engineers left to design server-grade chips, this was Nuvia, and they got sued by Apple to the point that they had to get acquired by Qualcomm.
rajnathani··on The perils of UUID primary keys in SQLite
Isn’t the case with Postgres too if one doesn’t change the default primary key index for which is B+ Trees? At least Postgres supports a hash index IIRC, but I’m not sure if most developers set it to that when they use UUIDs as primary keys.
rajnathani··on The Waymo World Model
Not really I think, they built a simulation engine for autonomous driving, for which tons of such exist out there including ones from Nvidia and also at least 1 open-source one. Using world models is different.
rajnathani··on Animated Knots
For these single-website to explain things, I really like that HN's 1-click link to view past submissions shows the past posts (I have seen this useful website come up in the past!):

rajnathani··on Aging muscle stem cells shift from rapid repair to long-term survival
Interesting point:

> The research suggests that increased NDRG1 expression emerges through what the scientists call a "cellular survivorship bias"—stem cells that don't accumulate enough NDRG1 die off over time, leaving behind a population of slower but more resilient cells.

rajnathani··on English professors double down on requiring printed copies of readings
This exactly.
rajnathani··on Apple buys Israeli startup Q.ai
If this works well, then I could finally see that AI wearable pins could be socially feasible. IMO speaking aloud in public to AI doesn't seem like something which will work but it is also what OpenAI is apparently investing a lot into with their hardware ambition with Jony Ive [0].

rajnathani··on Tesla ending Models S and X production
> Tesla’s far more popular models are the 3 and Y, which accounted for 97% of the company’s 1.59 million deliveries last year.

TIL that Model S hasn't been as popular. But hopefully when the 2nd gen Roadster finally gets released that it will fill in the slight gap left by Model S's discontinuation.

rajnathani··on People who know the formula for WD-40
As a side note: PTFE = PFAS forever chemical.
rajnathani··on Repatriate the gold': German economists advise withdrawal from US vaults
Even India recently has repatriated some of its foreign gold reserves (from Bank of England (and possibly other places)):

rajnathani··on Bugs Apple loves
Also, not on the list: iCloud having a hard limit of 50,000 total calendar events and silently not syncing beyond it (and similar to the first iCloud Photos issue mentioned on the website: no indication of syncing state to know what's going on). For perspective, as someone using the Apple ecosystem for 10+ years now, that this comes to 13 events a day for 10 years.
