simpsond··on El Salvador abandons Bitcoin as legal tender after failed experiment
None, really. They are all floating relative to each other. But USD is stable enough to know what you can get with $10. Although the last few years have put that to the test.
simpsond··on Stimulation Clicker
I needed the ocean at the end. It's a very good game. The variable reward and quick repeatability captured me... It showcases what we are exposed to in a condensed manner.
simpsond··on Zero-latency SQLite storage in every Durable Object
You have a row key, which gets consistently hashed to a shard / node on the ring.
simpsond··on Mice live longer when inflammation-boosting protein is blocked
Yes, too much niacin can make your entire body flush with a burning sensation.
simpsond··on Show HN: Tunnelling TCP through a file
But that will negatively impact the person who paid. That’s not cool.
simpsond··on Nvidia announces financial results for first quarter fiscal 2025
Some people care about PE. Some people don’t. It’s just one metric that represents past performance. If it’s high, the market believes the stock price will go up.
simpsond··on What if null was an Object in Java?
Yeah, I wish the VM would prevent null assignment of optional and force to empty. There are probably side effects I can’t think of here and certainly would cause problems with legacy code misusing optionals.
simpsond··on TSMC unveils 1.6nm process technology with backside power delivery
200 million transistors per square millimeter.

Gallons per mile only makes sense when you are talking about dragsters.

simpsond··on Intel Gaudi 3 AI Accelerator
Process matters. Intel was ahead for a long time, and has been behind for a long time. Perhaps they will be ahead again, but maybe not. I’d rather see them competitive.
simpsond··on Two Ethereum DeFi traders just made $120M using a strategy called 'looping'
Those accounts might not belong to individuals.
simpsond··on AWS charge for using IPv4 expected to bring $1B/year and speed up IPv6 adoption
You can technically route through one if you can tolerate that. But I agree. They just got more expensive.
simpsond··on Filecoin Foundation Successfully Deploys IPFS in Space
ACLs are compatible with some blockchains. Token gating, merkle proofs, and RBAC are fairly common in smart contracts. See: https://docs.openzeppelin.com/contracts/2.x/access-control#r...
simpsond··on Tesla Model Y 2nd in new vehicle registrations in the US, overtaking Toyota RAV4
Model Y takes the number two spot away from darling Toyota. Clearly, Musk has damaged the brand.
simpsond··on Ripple CEO says SEC has lost sight of mission to protect investors
How is that different from meme stocks?
simpsond··on Bored Ape conference attendees wake up with eye pain, vision loss
It’s actually a mapping between an unsigned integer and public key, stored on all nodes. It only requires a signature to persist the state change.
simpsond··on Tesla announces Cybertruck deliveries in November, with 125k production capacity
Maybe… Tesla doesn’t allow lease buyouts on some models. At least that is the case for my Y.
simpsond··on The Amazon Prime Day 2023 AWS Bill
You wouldn’t commit for 3 years for increased resources of a single day.
simpsond··on Smart Contract Security Field Guide
PoolTogether routes deposited funds to a liquidity pool on aave. Those funds can be lended out via over-collateralized loans. That’s how the interest is earned. They could of course use other types of pools and gain funds on swap fees etc.
simpsond··on Ask HN: How to price your first enterprise customer?
Consider giving a discount only on time commitment. The time burden with enterprise customers is heavy up front. Legal, accounting, compliance, etc. They will often prefer a commitment as well.
simpsond··on Programming languages going above and beyond
Verification of onchain protocols seems like a great fit.
simpsond··on China solar module prices keep diving
I got my equipment through a local wholesaler. I built a BOM using solardesigntool and submitted through them. The wholesaler called me and accommodated me as a DIYer. CED Greentech was the company.
simpsond··on US SEC sues Coinbase, one day after suing Binance
The primary use cases of ETH are changing state of the network and collateral for state change validation. Requester pays to effect change and some ETH is burnt and some goes to validators to incentivize operation. What other security does that? I don’t expect profit when using it to change state of the network.
simpsond··on HBO Max new Captcha system
I can’t imagine UX designers didn’t push back on this… it’s so obviously bad. PMs had their back to a wall.
simpsond··on Defining a new HTTP method: HTTP Search (2021)
It’s not exhaustive though. Many servers and proxies support it, but not all. For instance, GCP load balancers do not, but ALB does. At least that was case a few years ago.
simpsond··on Payments 101 for a Developer
That sounds like a protocol. It would be nice. Someone got downvoted for mentioning Bitcoin, but blockchains are protocols capable of transferring value.
simpsond··on Instagram Is Disabling Its NFT Features
Metadata isn’t part of the core spec, so NFTs don’t have to link to anything. You can only verify ownership of the NFT id. What the NFT represents is up to the author. It could be a credential to a web application. It could be a pass to a venue checked at the door. It could be anything to gate access by asserting if the wallet holder has a specific id or balance greater than zero of said NFT. An NFT is a unique token. What builders do with it is up to them. Mostly it’s been art. What else could builders do when they have a permissionless way to assert that a user owns a unique digital id (NFT). It’s worth exploring more.
simpsond··on Instagram Is Disabling Its NFT Features
They can point to a metadata URL, or store data. But the key is they have a unique id and can be used to verify ownership. Think of it like a global compound primary key: (chain id, NFT contract address, NFT id). For many things a database will suffice here, but it’s also useful to remove the dependency of a central authority. It’s worth exploring more.
simpsond··on 200-year old heat pump technology is back
I went with the Daikin 5MXS48TVJU for the condenser and 3 models of the head units. All Daikin. I didn’t want a bunch of condensers around the house, and I didn’t want to run power everywhere. I’m not sure about efficiency compared to multiple condensers or the IRA stuff.
simpsond··on Creation happens in silence
Almost OODA like. I have a similar process. I noticed that when I started taking cat naps mid afternoon, loaded with context, a solution would find me. Walks are good too.
simpsond··on 200-year old heat pump technology is back
The DIY Mr Cool has an extra 3kw heat option for colder climates. Not sure how well it works.
