I am fully aware what Cargo.lock is. What I am surprised at is how many dependencies there are.

I love llm coding. I don't know what I am looking at here

https://github.com/malisper/pgrust/blob/main/Cargo.lock

What is happening.

No PRs? No Make files? I understand running tests and debugging is the workflow, but where do you log things? How do you orchestrate builds? Etc.

Well, the labels are fundamentally misleading: According to the author's data, "40 people get 0.75 slices each", whereas that 30 slice pie is labeled as "Hedge funders, fascist VCs, and cosmetic surgeons". Even if you take a charitable view to bundle every possible related occupation, I can hardly understand how labeling 40% of the US population as "Hedge funders, fascist VCs, and cosmetic surgeons" is accurate.

The US has a very progressive taxation system: https://taxfoundation.org/wp-content/uploads/2023/01/FedData...

For working and middle class households, the US tax burden is usually lower than in most European states, especially once payroll/social-insurance taxes and VAT are included. The US federal tax system is also very progressive by OECD standards, so upper-income households carry a larger share of federal taxes while the lower/middle bear less of the explicit tax load

Of course, wealth is not exactly income, etc

Even if it's 1-3 years, they are very likely to be ROI positive all in.

Right, especially given that majority of this investment is into GPUs and data centers that are amortized over a longer period of time. This is actually very hopeful.

Given how the curves look like in terms of ramping of spend, these are very healthy numbers.

New comment by diziet in "Show HN: One clean, developer-focused page for every Unicode symbol"

diziet — Tue, 30 Dec 2025 16:02:29 +0000

Cool! Ideas: At least do an ensemble approach by queuering llms to explain what the symbols "are". It's so auto generated now. Link to wikipedia. https://en.wikipedia.org/wiki/Approximation#Typography

Developers need to understand context too, not see a static page of "macOS: Use Character Viewer (Control + Command + Space) and search by name, or copy/paste."

The related to symbols make little sense. For example: https://fontgenerator.design/symbol/acute-angle Does not link to all other "angle" pages, but does to Aktieselskab?

I would also love to see a token budget use for the chats -- to know when the model is about to run out of context. It's crazy this is not there.

Thank you for sharing this and elaborating on what I've seen firsthand. Another thing we've noticed is that an increase in VO 2 Max, which does take quite a bit of time to change, makes a major difference.

Altitude is another factor, due to dry and colder air and lower oxygen -- a double whammy for asthma.

I don't have a horse in this race, but from my personal experience eating satiating whole foods with lower glycemic index, higher fiber and protein content makes it very difficult to gain excessive weight.

On the asthma front, from experiences with someone close to me -- getting in great physical shape (with caveats regarding training) DID indeed help greatly with broncho-constriction and higher scores on FEV. Basically symptoms and inhaler use went down tremendously over a few years and a physical transformation.

I am surprised that there isn't a comprehensive test suite of (at least) virtual button presses replaying actual typed sentences for a product used by so many people that apple would run on a daily basis against each device.

New comment by diziet in "The fuck off contact page"

diziet — Mon, 08 Dec 2025 09:27:09 +0000

"You will get less leads with the 'enterprise style' contact page. You don't have enough leads right now. You don't have low value self-serve users you want to turn away. Your BDR team is not overflowing with leads you need to turn away. You can make money from having more leads. Less leads will generate less revenue. Here are some potential metrics from the two styles of contact pages. Here is how these metrics tie into revenue."

I think an honest message like this, at least communicated via email to the budget owners would abscond... or at least absolve one of any guilt.

Also, thank you for having the option to toggle the font. I wrote a css rule, but found it later.

An unfortunate yet unsurprising report to those familiar with the literature on cognitive ability. I too donated to similar programs. I hope better computer skills make some sort of earning impact, though the prevalence of smart phones probably makes a bigger difference.

> NVIDIA's total annual revenue for its fiscal year 2025 (ended January 26, 2025) was $130.5 billion

It is clearly not in the same order of magnitude

The A100 SXM4 has a TDP of 400 watts, let's say about 800 with cooling etc overhead.

Bulk pricing per KWH is about 8-9 cents industrial. We're over an order of magnitude off here.

At 20k per card all in price (MSRSP + datacenter costs) for the 80GB version, with a 4 year payoff schedule the card costs 57 cents per hour (20,000/24/365/4) assuming 100% utilization.
