Lemmy.world is not frowned upon. There are some people who are very vocal about not liking it but if you don’t have any problems you don’t need to change. There is also nothing stopping you from having accounts on diferent instances so try some of them out and stay where you like it.

The point of the fediverse is to give people the option to create communities by themselves and not be subject to the ruling of one central allmighty entity. If someone does not like one community they have the chance to create their own with their own rules. This means people can decide for themselves what content they want in their community. However people coming from traditional social media seem to mistake this kind of freedom with not needing to follow any rules but that’s not how it works.

Quite happy that today went a lot smoother than yesterday even though I am not really familiar with recursion. Normally I never use recursion but I felt like today could be solved by it (or using trees, but I’m even less familiar with them). Surprisingly my solution actually worked and for part 2 only small modifications were needed to count peaks reached by each trail.

Oh today was a struggle. First I did not get what exactly the task wanted me to do and then in part 2 I tried a few different ideas which all failed because I changed the disk while I was indexing into it. Finally now I reworked part 2 not moving the blocks at all, just using indexes and it works.

I feel that there is definitely something to learn here and that’s what I like about AoC so far. This is my first AoC but I hope that I won’t have to put this much thought into the rest, since I should definitely use my time differently.

I was surprised when my solution worked for part 2 since I thought you also had to include fractions of antenna distances, but apparently not.

Took quite some time to debug but in the end I think it’s a nice solution using base 2 and 3 numbers counting up to check all operator combinations.

			if op == 0 #+
				res += eq[i+2]
			elseif op ==1 #*
				res *= eq[i+2]
			else #op==2 ||
				res = parse(Int,string(res)*string(eq[i+2]))
			end
		end
		return res
	end
	opInt::Int = 0
	operators = Vector{Int}(undef,length(eq)-2)
	while opInt < (withConCat ? 3^(length(eq)-2) : 2^(length(eq)-2))
		withConCat==true ? operators=digits(opInt,base=3,pad=length(eq)-2) : operators=digits(opInt,base=2,pad=length(eq)-2)
		#calcEq(eq,operators,withConCat)==eq[1] ? (return true) : opInt -= 1
		calcEq(eq,operators,withConCat)==eq[1] ? (return true) : opInt += 1
	end
	return false
end

function calcTotCalRes(equations::Vector{Vector{Int}},withConCat::Bool)::Int
	totCalRes::Int = 0
	for e in equations
		checkEq(e,withConCat) ? totCalRes+=e[1] : nothing
	end
	return totCalRes
end

I’m also struggling with part 2. At the moment I am following the path and in each place I look if can connect with an earlier part of the path to the right by placing an obstacle, but without cutting off another earlier part of the path with that obstacle. I have indexes for each path location to see where in the path they first appear.

However at the moment I still have a bug counting too many possibilities. Any other ideas?

Julia

No really proud of todays solution. Probably because I started too late today.

I used a dictionary with the numbers that should be in front of any given number. Then I checked if they appear after that number. Part1 check. For part 2 I just hoped for the best that ordering it would work by switching each two problematic entries and it worked.

Julia, since I used it for some projects this year but never for something “time critical” like AoC with a new problem each day. I really like that it’s simple like python but with strong typing. Originally I wanted to use Ocaml to learn it, but on day 1 I realised I don’t know how to do anything in it yet 😄.

I guess if you want exciting new features you can just switch to a different distro nowadays or add them yourself. Why should distros add more stuff making them bloated or change stuff turning users away that like how things are currently? For general use you really don’t need a lot of fancy new stuff.

I tried it and liked that they have quite some documentation for how to do things like get to a desktop. However I couldn’t get audio working so I stopped using it, but I am also not really experienced in setting up Desktops so maybe it’s easy.

Please keep us updated about how this is going to work out in the future.

Depends on what you want to do I guess. I’d rather have a clean desktop that cannot accumulate clutter like in windows where applications add shortcuts to the desktop automatically which you then have to remove manually.

I actually really like not having icons on the desktop in gnome. It always ends up a collection of random garbage anyway after some time and Icd rather have that in my home directory. Now i can just press my keyboard shortcut to hide all windows and then I have a clean screen with nothing distracting me.

It’s Aldi in Germany. Running Linux however does not prevent these machines from getting errors all the time so often times there are only 3/6 machines available since an employee has to reset the software manually.

I saw the self checkout machines in my supermarket being restarted a few times and caught a glimpse of what was shown on the screen. Before they were upgrade some time ago they showed that CentOS was running and now I think that I saw Rocky Linux running on there. So yes, these are definitely out there and used widely.

Also I’ve see pictures of Raspberry Pis being used almost everywhere.

I got it work too but wouldn’t call it easy. My process involves going to about:config to enable some variable that has a super long name. Then find out where the profiles are saved and remember not to use the “cached” directory version which I always end up on first. Then selecting one of the cryptic profile names and creating some specific directory structure and copying or linking (but no soft linking) my config there.

A simple checkbox in the settings would be nice, or another browser extension. Or is there an easier process?

If only it was easier to remove the default tabs from firefox so you don’t have duplicate tabs. I recently had problems getting the userCSS to do its thing, trying different directories. In the end the problem however was that I tried to link it with a symbolic link which for some reason doesn’t work.
