If you like jazz piano, Keith Jarret’s köln concert is a masterpiece.

There were a bunch of issues with the venue and he ended up playing the whole thing on a broken piano.

This video sums up how the peice happened.

And this is recording

Edit: I like to think it’s a story of stacked disasters and a master artist somehow making the whole mess gorgeous.

Stream of consciousness from train of thought and dance of eternity from meteropolis pt. 2 are really good, long-ish instrumentals that kind of tell a story.

And to answer OP: Metropolis pt.2 by dream theater is a great concept album that has an interesting story to follow.

I had forgotten about maggot brain, such a great song! Thanks for reminding me.

A greedy crow is what they told me

It’s intriguing, though, who’s in front, who’s in the back, and does it even mean anything?

I’d like to see your solution in total. I’m not too familiar with the nuts and bolts, but hash set is quite a bit more expensive than a simple vector, there’s a bunch of overhead incurred when executing the hashing and placing of the data, and when repeating a few thousand times it sure adds up. My part one hovers around 600 microseconds.

Not who you asked but: I save coordinates and direction into a vector each time the guard faces a #. Also every time the guard faces a #, I check if the position exists in the vector, if true, it’s an infinite loop. 78ms rust aolution.

Rust

This one was the first real think for this year, but I ended up brute forcing it, placing a ‘#’ in every position and checking. part 2 runs in about 380ms 78ms (after reducing the amount ‘#’-placements to only where the guard walks) on my 2011 core i-7, so I’m happy, even though it feels like I could have been smarter.

Part 1 Part 2

I think that’s mostly the poison talking

Still in rust, and still inexperienced.

Forgot to make a separate solve for part two, for part one, imagine this without the make_valid function and some slightly different structure changes around the accumulator in babbage().

Used a hash map to track what should be in order, and a few indexed loops to keep track of where I’m at and where to look forward.

Day 5

This looks so alien! Does it work with the full set? The comment says 5, choose 4, but I guess it’s written as n, choose n-1?

This is my very naive rust solution, part 2 is mostly just an extra function, so they’re bother covered in this one.

AoC day 2

I’m quite inexperienced as a programmer, I learned most of the basic concepts from playing human resource machine and 7 billion humans. After mucking about writing some CLI utilities in Perl and python, I’ve decided to give rust a go.

Part 1

Part 2

Thats actually a cool idea, I’m learning rust these days, and building a personal news feed feels like a doable project with a ton of useful lessons built in. Thanks!

Why should I willingly expose myself to a firehose of increasingly terrifying news that I can do absolutely nothing about? The only possible outcome of consuming that media is increased anxiety and stress on a personal level, so I want to limit my exposure.

I’m sure if anything important happens, I’ll pick it up through osmosis anyway.

Thanks, I’ll look into what the Firefox extension community has. For now I figure I’ll go down to the pub, have a pint, and wait for all of this to blow over.

Thanks, I’m using voyager and am filtering some keywords already. While it helps a good bit on here, I guess I’m more looking for an ad block extension for Firefox, but for trump and trump adjacent content. Ideally something that includes what his business partners and associates in the government are up to.

Thats really Cool! Thanks for letting me know, this might be the impetus I needed to go back to working on the 220 camera!

Hi!

I’ve only ever managed to get the lide30 to play nice. I have destroyed one 110 and two 220-scanners in my efforts to build a more versatile rig.

What happens if you drop the prism back in?

I’ve also speculated about there being som calibration and automatic gain control going on in these newer models. I believe it could be used to normalize the values coming off of the individual sensor segments.

On my latest attempt at a 220 scanner, I actually built a small dimmable LED circuit that I attached externally to try and influence the calibration I thought was happening, but there was a disappointing lack of results. Come to think of it, I still have that rig laying around somewhere, and the experiment may have been flawed, I’ll have a look next time I’m at my workshop. I’ll let you know what I find.

I know that rig is at least functional, as objects placed directly onto the glass renders crude shadows on the scans.

That’s the long answer, the short answer is no, I don’t have any tips, maybe aside from working on fooling the possible calibration somehow.
