elurg··on To revive Portland, officials seek to ban public drug use
How the fuck was "public drug use" not already illegal?
elurg··on C uses "&" for the address-operator because 'ampersand sounds like "address"'
Also Pascal.

And C++/CLI uses ^ for "managed pointers" (pointer to .net objects) and % for "managed references" which means there are all-together 4 ways to declare various types of pointers which is super-fun.

elurg··on C uses "&" for the address-operator because 'ampersand sounds like "address"'
Pascal uses this syntax.

Also "pointer to integer" is written as "^integer" which is better than "int".

Syntax also doesn't allow confusing stuff like like "int a, b;".

elurg··on Shrinkflation Tracker
Most of these products are extremely unhealthy so shrinking portions should be considered a public service.
elurg··on Hypersonic missiles are misunderstood
The US currently has a large advantage is mass-to-orbit capabilities that is set to explode once Starship comes online.

Elon needs to talk less about peace with Russia and more about deploying weapon systems. He can make enough money from it to retire on Mars.

elurg··on So what was that? Was Starship’s launch a failure or a success?
> The Soviets abandoned that project because they couldn't get their 30 engines to synchronize. Maybe this time AI (c) will help solve the problem. We will watch and see.

Worth mentioning that N-1 was severely limited by the state of electronics technology in late 60s Soviet Union. The first 3 launches of the N-1 rocket didn't even have a digital flight computer, they relied on an [analogue system](https://en.wikipedia.org/wiki/N1_(rocket)#Engine_control_sys...).

The Space Falcon Heavy uses 27 engines and it has a perfect reliability record over five launches. Having many engines on a rocket is a solved problem and it even brings some advantages - you can still reach orbit if you lose one or two of them.

elurg··on ChatGPT is going to change education, not destroy it
I've been using ChatGPT for language learning by asking it to explain the differences between words. The answers align with what the dictionary says but are far more elaborate and better nuanced.

It wouldn't be possible to get equivalent explanations from native speakers unless you pay them to teach.

elurg··on Blue Origin makes a big lunar announcement without any fanfare
You're underestimating the political complication of sending nuclear power to the moon.

Solar panel manufacturing faces no objections.

elurg··on Investors conclude that Tesla is a carmaker, not a tech firm
Car companies deserve to have a severely depressed valuation because they're currently being forced to transition away from internal combustion. The ICE manufacturing industry is the worst one to be in because government are determined to kill you.

Tesla doesn't have this overhang and is also growing very fast.

elurg··on Microsoft is preparing to add ChatGPT to Bing
I asked it how to convert a cell value to an unix timestamp in google sheets and it told to use the "UNIX_TIMESTAMP" and even provided an example.

The function does not exist, it's entirely made up.

What's weirder is that when I told it that the answer was wrong it provided a different solution that was correct.

elurg··on Why Not Mars
A lot of stuff is known about it. Both the US and USSR first operated long-duration space stations nearly half a century ago.

Gravity and radiation are well understood and we can definitely build machinery that can tolerate them well for many years.

> we have never entirely isolated a group of humans from the biosphere for even a year, never mind indefinitely. The times it was tried, it failed.

Why doesn't the ISS count? It gets resupplied every few months but a Mars base would be resupplied every two years so systems only have to scale to last 10x as long.

elurg··on Why Not Mars
Only national space agencies have had a reason to invest in keeping humans alive for long periods of time so they are the only organizations that have demonstrated that capability. It doesn't follow that SpaceX couldn't do it - they just didn't have a reason for it so far.

This idea that "life support" is the most difficult aspect is unfounded. The most difficult problem is transportation and reducing the cost of transportation means that you can attempt to solve every other problem by simply throwing more mass at it.

NASA does much of its work through contractors anyway and there are several companies working on independent space stations. I'm confident that the "life support is too hard" argument will be proven false in a few years.

A similar argument is made that "cryogenic fuel transfer has never been demonstrated at scale therefore Starship can't work". But nobody has even seriously attempted this! And the reason is that without reusable rockets every refueling mission is unbelievably expensive and the business case never closed.

elurg··on Why Not Mars
Life support is not particularly difficult if you can just throw mass at it.

It's probably true that Starship would only be capable to support 10 colonists all the way to Mars and that's still pretty damn good. This number will grow if you have a separate life support system on the surface and don't have to rely on the ship but the first missions will indeed have a very small crew.

elurg··on The FBI was the primary link between the intelligence community and Twitter
The FBI seized the laptop in December 2021, nearly an year before it was revealed. They knew it was real but they strongly encouraged media companies to "expect a leak". As a consequence of this the story was strongly suppressed and the general public came to believe the opposite of the truth.

It's true that the FBI didn't force companies to kill the story but the story was still killed as a result of FBI actions. Are you OK with the FBI misleading the public? Or are you going to argue that they are incompetent and genuinely believed that it was a Russian operation?

There is no proof that Joe Biden himself acted improperly but Hunter Biden did receive large consulting fees for performing no work - he spent his time on cocaine and hookers instead. This strongly indicates that he was hired for political connections.

elurg··on AI chatbots are not a replacement for search engines
Providing sources is the most important feature missing in chatgpt and perplexity.ai does indeed attempt to solve it. The other problem is that chatgpt is often factually incorrect and gives no hint of uncertainty.

I've been using perplexity.ai recently and often times the results are more helpful than google and it tends to spew less opaque bullshit than chatgpt.

elurg··on The world is burning more coal than ever before, new report shows
Germany genuinely believed that Russian gas will keep flowing.
elurg··on The FBI was the primary link between the intelligence community and Twitter
As far as I understand the FBI knew that the Hunter Biden story was real but encouraged everybody else to believe that it was a Russian hoax. Doesn't this count as lying? It's not just lying, it's explicit disinformation with an electoral goal.

This went so far that major web platforms blocked all forms of disagreement and the public dismissed it as a conspiracy theory. It was highly effective.

I hate Trump's guts but it's important to acknowledge the enormous amount of effort that went into covering up the behavior of Biden's son.

elurg··on The FBI was the primary link between the intelligence community and Twitter
A lot of people completely agree with heavy-handed information control.
elurg··on The FBI was the primary link between the intelligence community and Twitter
The distinction between the government "asking nicely" and "making demands" is not strong enough. In theory could Twitter could have resisted but the costs would have been quite high.

The government should be prohibited from making such requests.

It's also apparent that regarding the Hunter Biden story the FBI outright lied in order to make web platforms censor the story.

elurg··on The FBI was the primary link between the intelligence community and Twitter
The argument that "it's not censorship if a private company does it" was always weak.

What these revelations show is that a lot of so-called moderation was done at the explicit direction of government employees. How do you defend this? "it's not censorship if the private company willingly complies with government requests"? A refusal by twitter would have had quite high costs for the company.

The cooperation between private companies and government censors is so deep that this is barely distinguishable from direct censorship.

elurg··on The world is burning more coal than ever before, new report shows
This is a consequence of the Ukraine conflict - less natural gas means Europe needs to burn more coal instead. This situation is likely going to continue - relations with Russia are very unlikely to be restored any time soon.

Reducing CO2 by switching from coal to gas was never a durable solution (there's only a percent reduction) and now it's dead. The only way forward for Europe is much more wind and solar, now also as a security imperative.

elurg··on Twitter applies 7-day suspension to half a dozen journalists
Good. There should be zero tolerance for anything that approaches doxxing.
elurg··on Twitter applies 7-day suspension to half a dozen journalists
Publishing personal information should not be covered by "free speech" at all. It provides no value to society and can cause real harm to individuals.

Elon was wrong in that tweet. It would be much better to show zero tolerance to doxxing.

It doesn't matter if the data is already available from public sources - publishing aggregated personal information from public records is dangerous and should be banned.

elurg··on Fusion energy breakthrough by Livermore Lab
Why do we need to cover the worst case with 100% renewables?

The goal is to reduce emissions so it would be great even if we can just stop burning coal in the summer.

elurg··on Russia’s apparent resilience is being kept up by policy tricks and cash
Refugees are easier to handle than tanks.
elurg··on ChatGPT produces made-up nonexistent references
The next word is always chosen based on some sort of probability output, correct? Then why isn't it possible to notice when the highest probability drops and the output is likely nonsense? Being able to say "I'm not sure" would be a massive improvement to this model.

Another cool feature would be to provide sources for the information: which web pages contributed most to a specific statement. Then a human can follow up manually.

elurg··on Beyond Meat is struggling, and the plant-based meat industry worries
I really don't understand why people want to simulate the taste of meat. It seems like a completely uninteresting problem to solve, plant foods are already perfectly fine.

The availability of "perfect substitutes" for meat wouldn't affect my food choices at all and this is likely true for a lot of people.

elurg··on PayPal inactivity fee
I don't understand why people defend this behavior.
elurg··on Why was western printing superior to Asian printing?
Very few Chinese characters are pictograms and even those are extremely stylized.

The vast majority are complex compounds of smaller radicals.

They are nothing like emoji.

elurg··on Leak ruins NASA moon rocket launch bid; next try weeks away
Launch delays for new rockets are extremely common for all providers everywhere.

While there big problems with the SLS program such a small delay on the pad is not one of them.
