Look at this boy. He's demanding that I pat his head.

@npub1p45…89jz is it still true that no one has ever taken you up on this offer?

@npub1knz…c73p I wonder if crowdfunding could be an option. Perhaps it's mentioned in the interview, I have to watch it. Thanks for linking it.

@npub1knz…c73p I would so much love to see more Æon Flux (the animated show). I wonder why they didn't make any more, and instead made the very disappointing movie.

This message when looking at a locked Windows computer never ceases to baffle me.
It's not like the OS doesn't know it's running on a laptop. And trust me, holding the power button and pressing the volume control is not going to unlock it.
Pressing the power button is just putting the computer to sleep, and holding it will turn off the power without a shutdown.

@npub1up2…k6en which solaris version are you installing?

While working on the function graph support in my language, I just randomly did a plot of cos(x) and sqrt(x) at the same time, and noted that they cross at about x=0.641.
My question to all the #maths people out there: Is there an analytic solution to this?

I've started working on a way to visualise how array operations work in Kap:

@npub1fzx…t6h3 @npub1rqv…nkck I note that I see apam from domains that don't have a working instance running on it (it was some search engine) so I'm not sure they even create accounts to do this.

@npub1axm…dsle Your comments have caused be to rethink the entire idea of uploading to youtube in the first place.
Of course invidious is better than not using it, and in the case I need to link to one of the videos, I'd definitely use it if I remember to.

@npub1axm…dsle Oh, I don't disagree. It doesn't make me feel any better about having to use them though.

2024-02-17 10:46:29

@npub1axm…dsle Invidious just hides the problem up google abusing people's content. I'd much prefer to not upload anything to them at all.
I really need to find a peertube server that is reliable (I've had issues with my instance). I'd definitely pay for it, just not 60 dollars per month.

2024-02-17 10:25:00

I've had to turn off the Peertube server, since paying 60 SGD per month for just a handful of views is not worth it.
I'm putting some of my Kap screenshares on youtube for now, even though it gives me a horrible bad taste in my mouth.
If anyone has some suggestions for alternatives that are less costly, I'd love to hear them.

It's so disappointing that there is no way to easily create an overlay "Please wait" box when performing some long-running operation in a web application.

@npub1jeq…jglm After reading your review, I downloaded the third game from Steam and started playing.
It's good. But it sure is difficult to see what you are actually fighting, since you have to constantly look at the bullets.
Is the second game better?

@npub1jeq…jglm I have never seen any Boll movie, but I remember reading that Postal was one of the few that was actually not terrible.
I mean, based on what I've heard about the other movies, I wouldn't expect a masterpiece, but I was surprised that it was given somewhat positive reviews.
Now, I tend to trust you more than random comments from a couple of decades ago, so I was wondering if you've seen any of his other movies?

@npub16uk…pv7k @npub1vz8…708j What makes things worse is that even if you want to do it correctly, especially Word makes it unreasonably difficult to do so because every time you dare to paste anything into the document you have no idea what the styling is.
Brought to you by "Oh, this must be a header 1, it looks ljust like the others. Nope, it's a header 2 that has been manually styled", and other bestsellers.

@npub1683…f0qg To me, the main issue is that once again the US is incompatible with the rest of the world.
Now, I know that the charging ports were already incompatible, so sticking with the US version of the CCS port wouldn't really be much of a difference.

I think musk knows that he can do whatever he wants to his fanboys and they'll still defend him.

@npub1kzk…k9tq I've migrated my important projects to codeberg, and will do the rest when I have time. I have no desire to interact with github anymore, and so far codeberg has been everything I've needed so far.
The only issue I have had is some performance problems with the CI, but I don't think the CI is production quality yet.

@npub19kv…m4nu well, yes. XML has one thing sexps does not. It has the ability to be parsed and programmatically modified without changing the structure or comments.
Doing that with sexp would require a new type of internal representation. Such representation may exist but I'm not familiar with it

Having attended several talks at Black Hat, I have come to the conclusion that Microsoft could fix 90% of all security exploits by removing calculator.exe.

When the Star Citizen kickstarter was announced I put about 35 dollars into it because why not? I'd get the game, and if the project failed I wouldn't have lost much.
What I didn't expect was to still be getting progress updates mailed to me over a decade later.
I wonder if anyone has compared it to Hurd. Someone really should because it's on that level.

Someone posted the very funny and also thought-provoking joke that the most common national celebration is independence from the British, being celebrated by 65 different countries.
Which 65 is crazy high for an independence celebration, it's definitely not the most common celebration. International Workers Day is celebrated by 110 countries if I'm getting my count right. Are there any others that are more widely celebrated than that? (excluding religious holidays)

#[0] In any case, it doesn't really matter if this one will work or not.
A lot of people want it, and if there is no "official" solution, an unofficial one will be created, be it this or another one, and there is very little if anything any of us can do about it.
It would have been nice to have some kind of privacy-respecting federated search, but given the situation that would probably never get broad acceptance, so eventually someone like google will just suck it all up, use it for their index (and language model training) and we're all worse off.
None of this is good news.
