skylabmelody··on Writing memory efficient C structs
My suggestion is straight from the C++ guidelines by Bjarne Stroustrup and Herb Sutter (ES.102: Use signed types for arithmetic), for reasons that you don't seem to grasp.
skylabmelody··on Writing memory efficient C structs
I would suggest to never use unsigned int for values that will involve any sort of calculations on them (health, damage, speed). This is considered bad practice due to overflow and should be avoided, with the exception of values that are used for UIDs, indexes, bitfields, mask and flags.
skylabmelody··on Serious incident to the 777-300ER on 5 April 2022 at CDG [pdf]
Quite incredible that the aviation industry haven't introduces sticks with force-feedback despite video game industry having them for about 30 years.

Probably because it's a patent lawsuit minefield.

skylabmelody··on Serious incident to the 777-300ER on 5 April 2022 at CDG [pdf]
By "dual input system" I was referring to the fact that both pilots can apply input into their sticks or trim wheels simultaneously resulting into inputs cancelling each other out or de-synchronizing.
skylabmelody··on Serious incident to the 777-300ER on 5 April 2022 at CDG [pdf]
I don't want to minimize pilot errors but I can't stop thinking this dual inputs system easily ranks in the top 5 of the worst design ideas in history.

Probably just behind the MCAS.

skylabmelody··on Sabine Hossenfelder: “I believe chatbots understand part of what they say”
Once you know roughly how ChatGPT works under the hood (see ChatGPT API), most of these claims on ChatGPT seems to emerge from us humans being easily tricked by our own anthropomorphism.

skylabmelody··on Estonia’s inflation hit 25% year-on-year in August, energy prices to blame
Bloomberg:

"China is able to secure cheaper supply and resell shipments from more expensive exporters to utilities in Europe and Asia, while Russia can continue selling fuel at a profit."

https://www.bloomberg.com/news/articles/2022-09-08/china-sna...

Financial Times:

"The world’s largest buyer of liquefied natural gas [China] is reselling some of its surplus LNG cargoes due to weak energy demand at home. This has provided the spot market with an ample supply that Europe has tapped, despite the higher prices."

skylabmelody··on Former Coinbase PM charged in cryptocurrency insider trading tipping scheme
There is nothing whatsoever that says that the given employee is Charlie Lee. Since you are the one here making that claim, isn't that exposing you to slander if it turns out to be a false? On top of it you seem confused by the two different things addressed by the linked CFTC statement, the litecoin related thing (Litecoin/Bitcoin trading pair) happened in August & September 2016 (6 weeks total) and you are confusing it with the inaccurate reports during January 2015 and September 2018 which is a separate point.
skylabmelody··on Former Coinbase PM charged in cryptocurrency insider trading tipping scheme
Why you keep spamming that link here? That twitter thread is built on a layer of conjectures with nothing tangible.
skylabmelody··on Former Coinbase PM charged in cryptocurrency insider trading tipping scheme
That was a painful read. An "investigation" made by an anonymous twitter user based on cherry-picked tweets, hearsays and full of speculations. Many factual errors as well he didn't sell at all time high and the timeline doesn't match either. The claim regarding Litecoin increase and a supposed Bitfinex escape is made up as well.
skylabmelody··on Former Coinbase PM charged in cryptocurrency insider trading tipping scheme
Charlie Lee made all his fortune from selling his Bitcoin and Ethereum the rest is marginal. His track record regarding the launch, support and development of Litecoin is impeccable and rather unique in the space. Even half a decade after having no stake in the game he's still dedicating his life to promote and develop Litecoin.

skylabmelody··on TikTok overtakes YouTube for average watch time in US and UK
Just like Youtube scrapped from its search results the full version of that July presidential town hall video because it was not looking so good.
skylabmelody··on Costa Rica Has Run on 100% Renewable Electricity for 299 Days
"That means the government did not burn any oil, coal, or natural gas to power the country."

This is a new low for HN to upvote such garbage, but at least they edited the headline which originally was:

"Costa Rica Has Run on 100% Renewable Energy for 299 Days".

skylabmelody··on Exposing Tether [video]
I agree on the massive risk associated with the usage of Tether and stable coins in general. It's working until one day the music stops.

Regarding how it would affect the market, it seems all experts automatically assume that it would impact the price of cryptos negatively however:

• Could a panic exit from Tether push people to immediately buyback cryptos at any price?

• Could a flash pump of BTC while USDT/USD is unpegging be the signature of the downfall itself?

• Since stable coins are used for day trading, would their downfall make the crypto-market behave like it was before stable coins were introduced?

skylabmelody··on CPB director: The Netherlands must ban Bitcoin and other cryptocurrencies
You could make it illegal by law tomorrow, it doesn't change the fact that bitcoin would still exist and be used due to its decentralized nature.
skylabmelody··on CPB director: The Netherlands must ban Bitcoin and other cryptocurrencies
I can understand your fierce will to ban crypto for environmental impact reason.

However you cannot ban bitcoin, you just can't, that the whole purpose of its existence.

And black markets have always existed and always will.

skylabmelody··on CPB director: The Netherlands must ban Bitcoin and other cryptocurrencies
I don't think it is technically possible to ban bitcoin, only centralized exchanges.

If a country decides to ban exchanges, it could end up creating an untraceable black market since people might start exchanging crypto <-> cash in the streets.

Intelligence agencies would probably not be happy to lose such traceability capability.

Drug dealers would be taking over this black market as it creates new incomes while simultaneously helping some of their money laundering needs.

Blockchain startup ecosystem and crypto friendly entrepreneurs would leave your country. You would lose all related tax revenues and high-paying jobs.
