numtel··on Hunter-gatherers' work was play
If hunting/gathering is play and since that's basically what all animals do, then the blog's title, "play makes us human" is totally incorrect. Of course other animals play, we've all seen it.

It seems the opposite: toil makes us human. Our inability to accept what can be foraged has pushed us into working.

numtel··on FDA approves a CRISPR-based medicine for treatment of sickle cell disease
I was wondering about new digestive capabilities recently and wrote this blurb:

If we could eat different things, we could give up agriculture and save a bunch of land and energy.

Hello, I'm a full stack developer interested in building EVM dApps. See my portfolio site for links to my previous work. I'm especially interested in projects using Proof of Personhood or Sybil resistance.

numtel··on How to Build a Better Social Network
> When a user joins a platform, they are given 1,000 points.

The article doesn't go into how they would limit users from creating new accounts, (i.e. sybil resistance) which would be very important if you give out points like this.

> Every 10 minutes, the system slightly reallocates points.

The article author does not make any comparisons of their calculation to a reddit/hackernews style calculation, which already does has this kind of effect. See this article [0] or my Javascript implementation [1]

I made a reddit clone [2] that kind of follows this principal: Anyone can make a board which has its own ERC20 token. Upvoting/downvoting costs 1 token. Upvotes tokens are sent to the message author. Downvotes are burned. Moderators have the ability to mint new tokens. I figured these tokens could become valuable if there were lots of discussions in a board since it would induce a demand to moderate the board.

I also made a different site [3] that changes the decentralized moderation system so that instead of democratic upvotes, the message owner gets absolute discretion over the sorting of the replies they receive. I've put much more work into this one so it works much better.

numtel··on California Personalized License Plate Requests Flagged for Review 2015-2016
Right at the top of the list: octocat.

Good thing California is saving us from the sexual nature of GitHub's mascot.

Uh, our money does already expire. It's called inflation.

numtel··on The fake browser update scam gets a makeover
Again, that's for a validator node. If you're running a mirror that's not taking part in making new blocks, you don't need the speed, just enough space. It may not be always synced to the latest block but it should work.

I believe there's other requirements for BSC validators too, like staking a bunch of BNB.

numtel··on The fake browser update scam gets a makeover
It's not magic but it is a radically different pricing model: pay once, host forever.

I see it as a massive bet on storage prices continuing to decrease.

numtel··on The fake browser update scam gets a makeover
Anybody can spin up a mirror node, even on the mostly centralized BSC. This is just a misunderstanding.

Every public blockchain works this way afaik. I've even made a site for hosting webpages on Optimism: https://newgeocities.com

The real discussion imo is that blockchain node operators should be pressured to respond to concerns about unwanted content. There's no reason they can't coordinate on filters in the same way Ethereum validators use Flashbots to ignore Tornado Cash transactions. Although I hope they can find a better solution than blocking entire contracts because it's really nice to write a simple contract for data storage. Remember: a contract is a protocol, not a program. The validators follow the instructions but it's more like a database schema to which people submit conforming messages. As the contract creator, you're just publishing your code on chain. Each user takes responsibility for their own data.

Please tell my why this prompt is blocked by Bing's image creator then: "view from inside a shark's mouth as it hunts fish" but "view from inside a shark's mouth as it looks for fish" is fine.

A shark hunting is over the line but it can look for fish fine?

numtel··on Living in privately rented homes linked to faster biological ageing, study finds
Exactly. I paid rent during the pandemic then afterwards, California paid landlords for any missed rent money but they did not reimburse renters who did pay. What a scam!
numtel··on US sues eBay for allowing sale of emissions defeat devices
As a car driver without a cabin air filter, (are cabin air filters even effective against exhaust gases?) both diesel trucks and motorcycles require me to close my windows and vents because of the smell.

At least cars have smog equipment to reduce the emissions. Motorcycles mostly don't.

numtel··on Writing down unfiltered thoughts enhances self-knowledge
Before I graduated from college, my aunt gave me the book, The Artist's Way, which prescribes this basic task as you've described as the foundational exercise for creativity. The suggestion given was 3 pages a day no matter what.
numtel··on Should Ethereum be okay with enshrining more things in the protocol?
You're asking about undercollatorized loans on chain? It's not a solved problem but there's progress. See this survey of approaches of loans on chain. [1]

Last year for the ETHOnline hackathon, I made an app that allows anyone to request a loan in any erc20 token with (optional) collateral in any set of erc20s. In addition, the borrower identity is used to increase confidence: a linked Lens profile and/or verified passport using Coinpassport. The principal is then crowdfunded. [2]

While making this, I learned that Aave was originally called ETHLend and followed a similar model of requesting individual loans but this approach makes it difficult to attract liquidity so when they developed over-collateralized pools, the protocol became much more popular.

It's going to take better identity tools than we currently have. Of course, undercollatorized lending is the basis of traditional banking so replicating it on chain is a massive win for the ecosystem.

There's a few projects working on credit scores on chain: Sprectral [3] and Cred protocol. See this article about using Cred protocol [4]

For these kinds of things that don't take a ton of data, a blockchain is a great place to store them for a long time for one upfront fee.

How's it an investment if there's no liquidity? You can't sell your friendship on the market.

numtel··on $1 Billion That Nobody Wants (2011)
> In 2005, Congress decided that a new series of dollar coins should be minted to engage the public. These coins would bear the likeness of every former president, starting with George Washington. There would be a new one every quarter. So, far, the Mint has produced coins through the 18th president, Ulysses S. Grant.

Oh no, we're on course to make a coin with Trump's face on it.

numtel··on Industrial Civilization Needs a Biological Future
> I still don't quite understand his weird obsession with population size

I don't know the author's reasoning since it's not included but IMO, a greater population is valuable because it means more ideas and more chances for diversity. (especially with the vast distances of space)

Of course, this reasoning and I'm pretty sure your views resonate with the famous Stephen J. Gould quote:

> I am, somehow, less interested in the weight and convolutions of Einstein's brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops.

numtel··on Industrial Civilization Needs a Biological Future
That is some opaque language to say, "it's too expensive to have kids and this may cause the end of technological progress."
numtel··on I became addicted to running, and lost 26 lbs. All thanks to ChatGPT
My water heater stopped working a few weeks ago. I told ChatGPT what I was seeing and it told me which part to replace. I had never worked on a water heater before and fixing it was no problem with its instructions.

OTOH, I didn't realize until I got in there that there's only like 3 parts in a water heater so it wasn't as complicated as I imagined but I didn't have its breadth of knowledge.

History is considered to be since the invention of writing. (<10000 years) Anything before that is pre-history.

numtel··on What if they gave an Industrial Revolution and nobody came?
Go back to the ancient world and they don't care about your magic steam engine because it uses too much resources? Make one gun and they'll want to get better at extracting resources quickly.

James C Scott chronicles in his various books about how most people do what they can to avoid top-down control. Before such weapons of coercion, it would have been much more difficult to enforce the hierarchies suggested by industrialization.

numtel··on Why are so many young Americans adopting fake British accents?
There's an obvious connection in your two 'random' words: hitting the edge of one's elbow is commonly referred to as the "funny bone."
numtel··on We're afraid language models aren't modeling ambiguity
With the code execution plugin, one could theoretically ask chatgpt to generate a salted hash of their answer at the start that's revealed at the end to prove it was correct.

Without any plugins, chatgpt will happily return sha hashes and salts when I asked it to play rock paper scissors this was. The only trouble was, the hashes were totally wrong.
