The "oh but there's crime in fiat" argument holds no water.

Sure, HSBC facilitated money laundering and drug trafficking in Mexico. And when it came out, the fiat response was a huge outcry and putting a stop to it.

The crypto response is to say "screw the laws, let's go all in with money laundering and drug trafficking".

It's like noticing that kitchen knives are occasionally used for murder, and then concluding that it's a good idea to sell machine guns at every corner.

Fiat is indispensable, and (due to regulation) better for legitimate purposes than for crime.

Crypto is entirely dispensable, and (due to its inherent limitations (inefficient, slow, cumbersome)) better for crime than legitimate purposes.

Fiat currencies have collapsed in the past due to bad monetary policy (regulation is only good right?). Ask Argentinians how they feel about stablecoins after rapid inflation.

Alternative currencies offer competition and access. Why is that such a problem?

In the face of the never-ending list of these kinds of events, the laughably impossible task of average nontechnical individuals protecting their own assets (and the consequence of total financial ruin when they fail to do so), the overwhelming number of and size of scams, rug pulls, fraud, outright Ponzi schemes, and on and on and on… what exactly is left to keep anyone a “huge believer”?

Put differently, it’s been seventeen years of constant and escalating mayhem. What would finally be enough to shake your faith?

simpsond · 6 months ago
My faith would shake when scams, rugs, fraud, and ponzis completely stop outside of crypto.

> with turing-complete arbitrary computations in EVM this becomes very difficult.

I have very limited knowledge about EVM, but those computations are bounded by gas, right? Evaluating them is a finite process.

simpsond · 6 months ago
Yes, each opcode has a gas cost. Some are quite expensive, like writing storage (changing network state). Each block has a target gas limit. Say 30 million. A single transaction cannot exceed that. Additionally, a transaction specifies a bid on how much they are willing to spend, in ether, per gas. That said, transferring funds does not typically require significant gas.

What currency is stable in value? Certainly not the U.S. dollar.
simpsond · 7 months ago
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.

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.

If you adopt a wide-column db like Cassandra or DynamoDB, don’t you have to pick a shard for your table? The idea behind Durable Objects seems similar
simpsond · a year ago
You have a row key, which gets consistently hashed to a shard / node on the ring.

Doesn’t niacin lead to prettt severe hot flashes / flushing of the face and extremities? I know someone who was told to take it for cholesterol (I think) and it sounded painful!
simpsond · a year ago
Yes, too much niacin can make your entire body flush with a burning sensation.

You could just sniff the traffic for an already-logged-in MAC and clone it.

But that will negatively impact the person who paid. That’s not cool.

I don’t get the whole P/E thing.

Do people basically say we shouldn’t bother buying anything with a crazy P/E more than 20?

Despite the fact that these high P/E companies are now making people lots of money? Wtf?

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 commented on What if null was an Object in Java?   donraab.medium.com/what-i... · Posted by u/ingve
hedora · a year ago
An Optional is just a tri-valued null (null, None, and Some), so no.

It'd be nice if Java had a concept of a never-null reference (like a C++ reference vs. a C++ pointer), but the @NotNull annotation wasn't enforced the last time I checked.

Also, there's no way for an object to express that invariant because encapsulation is so weak. Given only this constructor (and no reflection):

   Foo() { foo.bar = new Bar(); /* foo.bar is final; Bar() does not throw */ }
callers can still get an instance of Foo with bar set to null.

Anyway, null handling in java somehow manages to be worse than C, where you can at least inline a struct into another, statically guaranteeing the instance of the inlined struct exists.

I can't think of another statically typed language that screws this up so badly. It just keeps getting worse with stuff like Optional and @NotNull.

(Disclaimer: I haven't followed java for 4-5 years; it's possible they finally fixed this stuff.)

simpsond · a year ago
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.
