diziet··on How Universities Should Prepare Founders
I think just as those who have never had kids, those who have never done a (successful) startup do not understand the value of PG's words - the same way those who choose not to have kids do not understand the joy of (having) them. There is great wisdom in PG's essay, and it is not vapid or wishy-washy.
diziet··on Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
I am fully aware what Cargo.lock is. What I am surprised at is how many dependencies there are.

diziet··on Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
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.

diziet··on American Wealth, Sliced Up
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

diziet··on Is AI Profitable Yet?
Even if it's 1-3 years, they are very likely to be ROI positive all in.
diziet··on Is AI Profitable Yet?
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.

There are colors in between blue and green that are neither blue nor green!

Basically all of life is self replicating, physically.
diziet··on Show HN: One clean, developer-focused page for every Unicode symbol
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?

diziet··on ChatGPT conversations still lack timestamps after years of requests
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.
diziet··on Weight loss jabs: What happens when you stop taking them
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.

diziet··on Weight loss jabs: What happens when you stop taking them
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.

diziet··on iPhone Typos? It's Not Just You – The iOS Keyboard Is Broken [video]
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.
diziet··on The fuck off contact page
"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.

diziet··on Evidence from the One Laptop per Child program in rural Peru
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.
diziet··on IBM CEO says there is 'no way' spending on AI data centers will pay off
> 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 font is very small. And unusual.

I would imagine a huge chunk of timeshare moved to individual creators that produce content on youtube in this space.
diziet··on OpenAI's H1 2025: $4.3B in income, $13.5B in loss
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.

diziet··on Sam Altman says Meta offered OpenAI staffers $100M bonuses
Whether this is true or not, this is a clever move to publicize. Anyone being poached by Meta now from OpenAI will feel like asking for 100m bonuses and will possibly feel underappreciated with only a 20 or 50 million signing bonus.
diziet··on WeightWatchers files bankruptcy
You can do more things to change your future healthspan than you can do things to change nuclear proliferation. A major positive impact of exercise is stronger bones and less risk of major injury from falling and other accidents.
diziet··on The US has exposed the World Anti-Doping Agency's precarious funding model
I am not sure if we read the same article, but the article I read specifically calls out funding by nations as problematic:

> This is because WADA relies heavily on funding from stakeholders, some of which have had the highest number of doping cases to investigate, such as Russia, China and the US. This in turn creates serious challenges for WADA in maintaining its own independence and impartiality.

The US has had more olympic medals stripped than China due to doping, but less than Russia [1]. This could be because China is better at hiding/masking it. It could be because US athletes get tested more thoroughly. However, the article calls out the relationship between funding and nations that are interested in doping and winning athletic competitions as problematic. Your... quick dismissive and berating diversion to our current administration is not very enlightening.

diziet··on Brood War Korean Translations
I was able to understand the Google Translate version well, but I am very familiar with the intricacies of BW and zerg 12hatch openers.

Chatgpt and Claude did an incredible job translating the korean text:

Claude:

  Today I'll teach you about the 12 Hatchery build. I'll explain the types of 12 Hatchery builds, their advantages and disadvantages, and the build orders in a simple but detailed way.
  Against Protoss, this is the build you use when you want to start with the most economic advantage. Against Terran, there are several builds you can do with 12 Hatchery, so I'll explain some of the most commonly used builds.
  The first is the two-hatchery build that starts with 12 Hatchery:
  12 Hatchery
  11 Spawning Pool
  10 Gas
  This build uses early gas, and it's often used when you want to quickly transition into a three-hatchery build with three gas bases.
  The second build is:
  12 Hatchery
  12 Pool
  12 Gas
  This build allows for moderately fast tech tree and moderately fast three-hatchery expansion. This build is commonly known as the "safe three-hatchery" build, and you can think of it as a build that enables both quick Mutalisks and quick third base.

Playing on a diagonal board is very frustrating. I estimate hard to be a bit under 2000 elo, medium around 1400.
