yeknoda··on Ask HN: What are good high information density UIs (screenshots, apps, sites)
This is good. The users this caters to are also higher than normal earners. Hate to ask, but what is the monetization plan?
yeknoda··on Spain proposes 100% tax on homes bought by non-EU residents
Depending on the market, market prices can be decided by a very small number of transactions that set things. Probably true for houses in Spain (limited supply) and foreign wealthy buyers (very high potential demand)
yeknoda··on Best Pens for 2025
Sad to see them ignore Stilform, which are really well built and with genetic latch. https://stilform.com/?gad_source=1&gbraid=0AAAAABRx75Fc4ynfn...
yeknoda··on How big data created the modern dairy cow
There is no way the 6x yield increase per cow did not negatively affect the taste, nutrition, and quality of the milk. Indeed, most of the "milk" you buy in large industrial countries barely deserves the term - it's got no taste or subtle flavor. It's even worse regarding derived butters and cheeses.

Yield is a great and easy thing to optimize becuase it's easy to measure. And if you increase yield at the expense of taste at suffiently slow rate, the change is impercetible to the customer. Happens slowly over decades so that a nice glass of milk is now like drinking dirty wash water. And a nice fat steak becomes ground up crickets and synthetics.

Moral of the story. Get your own low efficiency cows.

yeknoda··on Sora is here
something like a white paper with a mood board, color scheme, and concept art as the input might work. This could be sent into an LLM "expander" that increases the words and speficity. Then multiple reviews to tap things in the right direction.
yeknoda··on Sora is here
I've found using these and similar tools that the amount of prompts and iteration required to create my vision (image or video in my mind) is very large and often is not able to create what I had originally wanted. A way to test this is to take a piece of footage or an image which is the ground truth, and test how much prompting and editing it takes to get the same or similar ground truth starting from scratch. It is basically not possible with the current tech and finite amounts of time and iterations.
yeknoda··on Chinese pebble-bed nuclear reactor passes "meltdown" test
PWR pressure is on order 2-3x higher than an HTGR, so that’s a 2-3x thicker vessel. So good savings there

Is the cost of cryocoolong capex or Opex dominated?
yeknoda··on Of the 17 Y Combinator companies that IPOed, 14 have lost money for investors
Has anyone tried to see the net value generation of YC. Total revs - costs - money invested, all discounted appropriately. It’s been around long enough that the true net value created can be assessed, without resorting to BS valuations.

it's not plutonium. it's americium
yeknoda··on GPT-4o
feature request: please let me change the voice. it is slightly annoying right now. way too bubbly, and half the spoken information is redundant or not useful. too much small talk and pleasantries or repetition. I'm looking for an efficient, clever, servant not a "friend" who speaks to me like I'm a toddler. felt like I was talking to a stereotypical American with a Frappuccino: "HIIIII!!! EVERYTHING'S AMAZING! YOU'RE BEAUTIFUL! NO YOU ARE!"

maybe some knobs for the flavor of the bot:

- small talk: gossip girl <---> stoic Aurelius

- information efficiency or how much do you expect me to already know, an assumption on the user: midwit <--> genius

- tone spectrum: excited Scarlett, or whatever it is now <---> Feynman the butler

yeknoda··on Vietnamese property tycoon sentenced to death in $27B fraud case
Death penalty serves multiple purposes

1. Remove from society, with no additional cost to society. 2. Signaling to dissuade new offenders.

You can go one step further and punish the family, parents, and friends. Seems to be happening in the US for underage mass killers.

It’s a simple, effective, and low cost way to deal with crime of the highest magnitude. Why should it be off limits for corruption?

yeknoda··on Anatomy of a credit card rewards program
I wish stripe or some company would create a zero fee credit card that is truly equivalent to using cash. The wealth transfer from cash payers, merchants, and some card users to other card users and the cc companies is one of those gross injustices, a small and persistent leech on society. Surely there’s a way to do cc transactions for near zero? What is the point of all this tech otherwise?

yeknoda··on New studies suggest millions with mild cognitive impairment go undiagnosed
What are you going to do with the diagnosis? Charge them higher insurance? Tell em they’re dumb? Prevent them from driving? Give them a cash handout? Better not to know.
yeknoda··on SpaceX douments show company forbids employees sell stock if they've misbehaved
To some level, isn’t this an effective way to keep employees focused on the mission? The second you get a big payday you reconsider the need to work full time, the importance of family, health. You might even quit and start a new company with your pile of cash. All of which are not good for spaceX.

novelty is secondary to implementation
yeknoda··on AWS acquires Talen's 960MW nuclear data center campus in Pennsylvania
do not underestimate the magnitude of this news. it reveals there is basically negligible opposition to existing nuclear and limited or no opposition to new nuclear other than for cost reasons.
