dkjaudyeqooe··on Discrete Fourier Transform
All mathematic exposition feels that way.
dkjaudyeqooe··on Discrete Fourier Transform
Somewhat off topic rant, but am I the only one who find mathematical notation unnecessarily obtuse?

The bit that gets me is defining degree as n-1. For someone without a mathematical background, it takes a bit of pondering to figure out that you have to define n as one more than the actual degree, the opposite of what seems natrual. My mind at least just wants to think about n as the degree, and use n+1 as the last index. To me it seems aggressively unintuitive.

I guess you want to align the coefficient numbers but would it be a sin to define another index c = n-1 for that purpose?

But I'm a mathematical lightweight and maybe mathematical thinking is all about this. Perhaps some greater talent can correct my thinking.

All you're doing here is associating your hopes and dreams with grifters and charlatans.

They should be mocked and called out, it might leave room for actual innovators who aren't glossy incompetents and bullshitters.

dkjaudyeqooe··on Hacking Coroutines into C
A cleaner, faster way to implement this sort of thing is to use the "labels as values" extension if using GCC or Clang []. It avoids the switch statement and associated comparisons. Particularly useful if you're yielding inside nested loops (which IMHO is one of the most useful applications of coroutines) or switch statements.

dkjaudyeqooe··on Bulgaria to join euro area on 1 January 2026
This is nonsense. Not mentioned is that Greece has borrowed excessively and had defaulted on its loans. A bailout was organized by the EU and IMF with terms that Greece had every opportunity to reject. No one forced anything on Greece. The referendum was not binding and political theater for the government of the time.

That Greece accepted the terms reflected the reality that the alternative was much worse and would have caused great suffering for Greeks.

dkjaudyeqooe··on The economics behind "Basic Economy" – A masterclass in price discrimination
The large carriers, created through mergers that should never have been allowed, have the most popular routes locked up through ownership of landing/takeoff slots and similar. On those routes, fares have substantially increased due to a lack of competition.

The low cost carriers business model is to fly new routes (to secondary airports if required) at low prices, often creating new demand (Breeze is a classic example of this).

The math is very straight forward if you consider what each group is doing in the market.

Globally, big airlines seem to be doing fine:

I think there are lots of airlines that are propped up by governments that lose money leading to the meme you're quoting. Many industries were affected by the events you quoted, those sorts of things aren't specific to airlines.

dkjaudyeqooe··on The economics behind "Basic Economy" – A masterclass in price discrimination
Average airfare isn't a useful stat in this respect. What would be useful is comparing fares for individual routes over the years, which would tell a different story.

Average fares are skewed by low cost carriers entering the market.

dkjaudyeqooe··on National Archives at College Park, MD, will become a restricted federal facility
That's not what I'm talking about. It's the notion that if you get the corrupt to justify their actions that you'll somehow avoid corruption.

Fixing corruption involves people refusing to put up with corruption.

dkjaudyeqooe··on National Archives at College Park, MD, will become a restricted federal facility
This is the sort of bureaucratic nonsense people actually rail against.

You're assuming you'd get something truthful or informative out of that process, when in reality you'll get the opposite due to the inherit (dis)incentives.

More broadly, ignorance and stupidity amongst the general population benefit some politicians.

> If you travel internationally you get the added fun of dealing with border agents

That's avoidable. If you are a citizen of an advanced economy flying to another you can just use the automatic passport gates.

dkjaudyeqooe··on The economics behind "Basic Economy" – A masterclass in price discrimination
> Aren't flights at an inflation adjusted all time low

Yes, due to improved technology and equipment and because prices have been historically very high.

> most airlines operating at a razor margin

No, many airlines operate in imperfect markets and reap excessive profits compared to other airlines.

> All of the fat in the industry has been squeezed out

I don't know where you live but in the US this is patently not true.

Airlines are an abusive oligopoly there, with landing slots and the like cementing control of certain markets for certain airlines.

Ticket prices are much higher than they used to be and are much higher than Europe (for instance).

dkjaudyeqooe··on EU rules for durable, energy-efficient and repairable smartphones and tablets
This is not true for most people. They get comfortable with their phones and they don't see any reason to change something that works.

My friend has had her phone for 7 years and she's being pushed off it because apps are refusing to run on it now. No other reason than that.

dkjaudyeqooe··on U.S. bombs Iranian nuclear sites
How is "othering" people going to lead to peace? "Western liberals" aren't stupid or naive, they're just seeking a peaceful solution if possible.

And why are people so willing to believe that military force works? It mostly achieves nothing and leads to more violence.

It didn't work in Afghanistan, Iraq or Ukraine, but it will in Iran?

dkjaudyeqooe··on U.S. bombs Iranian nuclear sites
A non sequitur followed by a claim that Biden is responsible for Israel's security on the ground against Hamas.

Well Israel's security forces were out to lunch on that score, given how Hamas literately walked all over them, so I can see how you might think that.

But don't let me get in your way while you try to divert attention away from Trump's current recklessness.

dkjaudyeqooe··on U.S. bombs Iranian nuclear sites
Thats because they have friends with nukes (or thought they did).
dkjaudyeqooe··on U.S. bombs Iranian nuclear sites
This is probably the worst thing about Trump, he's let Bibi lead him around like a dog on a leash.

Any other president would be infuriated with Bibi's actions, because they would know he's cornering the US. But he knew Trump was a pushover.

dkjaudyeqooe··on U.S. bombs Iranian nuclear sites
There are reasons why presidents have avoided attacking Iran.

- massive instability in the ME. Just a few men with shoulder fired missiles can disrupt oil shipments from the biggest oil producers

- the high chance of being sucked into a forever war. Iran can cause a lot of problems with limited resources and can rebuild. They have no reason to give up and the US might have to continue bombing indefinitely, or launch a ground invasion.

- the increased chance of nuclear war in the ME. This action assumes that Iran has no backup facilities, or will never have, to continue building a bomb. Having already suffered the consequences, Iran has no reason not to seek a bomb.

dkjaudyeqooe··on Locally hosting an internet-connected server
Someone should tell Cloudflare that because it's not been my experience at all.

dkjaudyeqooe··on Locally hosting an internet-connected server
It's not really overzealous since not banning the CGNAT IPs just gives the abusers safe harbor.
dkjaudyeqooe··on Locally hosting an internet-connected server
> it does help you avoid being IP-banned

Actually all it does is get everyone behind the CGNAT banned. I've lost access to the WSJ and NYT recently, and other websites over time. For every Cloudflare backed website, I have to pass a captcha on every access.

Fuck those people doing "adversarial interoperability as a client", AI scraping, et al, who take away from thousands of people for profit, then move on to the next pool of victims.

dkjaudyeqooe··on Open-Source RISC-V: Energy Efficiency of Superscalar, Out-of-Order Execution
Very niche on the scale of LLM training data.
dkjaudyeqooe··on Open-Source RISC-V: Energy Efficiency of Superscalar, Out-of-Order Execution
I feel like an open source RV CPU is very likely in the high-performance space.

The amount of effort required to design and implement such a device makes it difficult for a single company to invest in, but many interested users of it could band together to create a viable open source implementation.

I guess it's a question of a project that such an effort can crystalize around.

dkjaudyeqooe··on Open-Source RISC-V: Energy Efficiency of Superscalar, Out-of-Order Execution
> Isn't translating between languages something that LLMs should excel at?

No, not at all. Unless there is a large amount of training data relevant to the translation then LLMs are likely just to make up nonsense. Chisel is a very niche hardware description language.

dkjaudyeqooe··on Implementing Logic Programming
Generally speaking, the advantage of logic programming is that it's (more) declarative: you describe the problem and it derives a solution.
dkjaudyeqooe··on A leaderless NASA faces its biggest-ever cuts
Musk tried to have a close associate installed as the head of NASA. Even if those facts are true there are many, many benefits Musk stood to get.

So although the GP comment is a bit silly it's still in the ballpark.

dkjaudyeqooe··on Don't guess my language
Indeed, somehow Google is the worst offender with this.

Lately they've decided that auto translating the local language into English in Maps reviews is the wrong thing to do. They translate every other language into English but somehow since I live in this place I must speak the local language too, so I don't need that in English.

Ditto for search results. Surely you want Wikipedia in the local language! I mean you've been there for so long! You search for things in the local language, surely that's a sign of your preference and not the fact that searching for things locally requires use of the local language.

This also applies to so much other "we must make our software so smart and guess all your preferences". Google fails so consistently at this I cannot understand why they persist other than some sort of misplaced corporate self regard.
