fabianfabian··on Don't believe ChatGPT – we do not offer a "phone lookup" service
ChatGPT does not know how to be correct, it only knows how to sound correct.

A better name for now would be PlausibleGPT.

fabianfabian··on Tweetbot is back down again
How? Can you even sign up in third-party apps? Those third-party app users were already Twitter users before. Maybe you meant they wouldn't remain Twitter users because they can't tolerate the default app experience?
fabianfabian··on Tweetbot is back down again
No, "Top tweets" has become "For You" and "Latest" is now "Following"
fabianfabian··on Tweetbot is back down again
Then I guessed wrong, thanks!
fabianfabian··on Tweetbot is back down again
Chronological timeline has not been removed. It is now shown more clear under the Following tab instead of the old starry icon.

My guess is the 3rd party clients need to stop filtering out the ads or risk making the suspension permanent.

fabianfabian··on Bitcoin hashrate drops nearly 40% as deadly U.S. storm unplugs miners
Numbers please, because it seems you haven't considered the possibility of it being cheaper.

The practice known as curtailment, is a way for miners to help electricity grids. The miners' steady demand ensures power producers are bringing in revenue to offset costs, but can power off when demand from other sources is high, such as during winter storms.

Sure, if double-spending has been solved for you, you don't need a blockchain. It hasn't been solved for everyone yet though. A great book to learn about this is: Check Your Financial Privilege (https://www.amazon.com/Check-Your-Financial-Privilege-Gladst...)
fabianfabian··on AWS and Blockchain
yes, the entire reason a bank is needed in all online transactions is because nobody trusts YOU to not double spend, but they do trust the bank to make sure they don't let you spend your money twice.

DNS is already decentralized, it's one of the most decentralized projects on the internet.

And while domains (not DNS) are less decentralized, it's all standardised and protocol based. If you want decentralized domains you need to champion for alternative DNS roots because all the technology is already there, just change the config file and get the people to do the same. Which is less effort than creating a whole new "blockchain" based system that does the same but slower.

This guy is exactly what's wrong with the crypto space. It's a fundamental misunderstanding of the strengths and weaknesses of blockchains.

Putting all those things he listed on a blockchain is the perfect example of “That's not a blockchain, that's a sequence of poor engineering decisions!”

Everything he listed can already be done with basic software engineering. Add a blockchain to these things makes it slow, adds unnecessary complexity and fake decentralization where its not even needed.

Crypto is full of Ape NFTs and casino gambling because there is nothing useful in blockchains other than removing trusted third parties.

Bitcoin added something new, crypto asked what more can we do with this? The answer is not much.

fabianfabian··on Bluetooth relay attacks allow Tesla Model 3 / Y to be unlocked and driven away
replay would be if someone legitimately unlocks the car and the attackers records the communication in order to replay it later.

relay is when the attacker takes the bluetooth signal of the owner in gym and relays it to the car in the parking lot.

fabianfabian··on 8880 Super Car (2010)
I remember always looking at this one in the stores as a kid, I could never have it because it was too expensive according to my parents. Over 20 years later I saw it on Marktplaats (Dutch eBay) and I immediately bought it, I haven't touched Lego in 20 years but this was the holy grail that I could never have as a child.
fabianfabian··on App is getting 500 server error. Cant connect
The keycard is just a back-up that you can keep in your wallet. Unlocking with the app (phone) happens automatically with bluetooth when you are near the car, no internet required. The main reason to use the app is if you want to unlock remotely for someone else using your car.
fabianfabian··on Show HN: Mako – a full Bitcoin implementation in C
There is no official implementation but http://github.com/bitcoin/bitcoin is most widely used to achieve consensus
fabianfabian··on An unexpected victory: container stacking at the port of Los Angeles
Hey take a look around in your room and find out where half of the things are made, and then reflect on who these consumers are you are talking about.
fabianfabian··on Cuba’s Bitcoin Revolution
It's $0.30 on the base layer and closer to $0.01 if you use lightning.
fabianfabian··on Mexican billionaire Salinas says his banking business may embrace Bitcoin
There is a difference between currencies, payment systems and settlements, Bitcoin can do all. Also, you forgot to list the dollar.
fabianfabian··on BTC Hashrate dropped another 27% down ~62% form peak now at 2019 levels
The protocol is configured to aim for 10 minute block intervals. If in a 2 week period there too many or too little blocks the difficulty to find a new block is adjusted for the next 2 weeks.

This drop is caused by miners moving from China to other countries.

fabianfabian··on US’ First Crypto Bank Reveals Date of Commencement
Payment systems are not currencies.
fabianfabian··on Tesla has closed its forums to launch a social platform and fans are not happy
Because having bitcoins preserves value, you might see it as spending but it is actually saving. They can still choose to spend it on hiring people if they wanted.
fabianfabian··on Show HN: See the Price of Stocks in BTC
Thanks for creating this! Over time BTC will become a better measuring tool for stocks than the inflated dollar
fabianfabian··on Ask HN: Is it time for social media posts to have digital signatures?
Yep signed tweets solve this and it doesn’t need to be perfect, it can even be partially automanaged by Twitter infrastructure just to restrict staff.
fabianfabian··on Bitcoin Gold hit by 51% attacks, $72K in cryptocurrency double-spent
Well it is, any copy cat coin sharing the same hashing algorithm as Bitcoin has this risk. So stay away from shitcoins.

Edit: I was wrong about BTG sharing the same algorithm.

fabianfabian··on Binance exchange hackers steal bitcoins worth $41m
Rollbacks can be considered for shitcoins, in Bitcoin it is nearly impossible and very unrealistic.
fabianfabian··on A faster, more efficient cryptocurrency
The reports of bitcoin environmental damage are garbage. (https://hackernoon.com/the-reports-of-bitcoin-environmental-...)

Bitcoin mining will accelerate environmental friendly energy production because excess energy can be converted into Bitcoin instead of going to waste. Miners who don't use excess energy will be priced out and there is plenty of excess energy around the world.

fabianfabian··on A faster, more efficient cryptocurrency
Not really. The biggest problem is getting more of the participants of the network bootstrapped with a fully validating node. Most people right now choose to rely on others instead which defeats the purpose of Bitcoin and makes the network overall insecure.

Is this a serious question?
fabianfabian··on The Real Issue with Facebook
This is where laws and regulation can come in, and its not just about Facebook, data about you is being collected and sold without your consent. What kind of person you are (to advertisers) is not being decided by you but by the data collectors and you have no control over it.

I don't think they would lose too many people, Facebook does connect families and friends in a way that provides real value to people. The people who quit Facebook this week will probably be back on Facebook in no less than 2 months and I think everyone would be more comfortable using Facebook if they can control how their personal data is collected and sold.

fabianfabian··on Blockchain Demo [video]
its just named that way, probably as in you don't try the same number twice for finding the hash of one block. The same number can be used for other blocks or even the same block if you change something else in it (like add more transactions).
