Apologies if this isn't an appropriate place to post this.

Inspired by a paper I found a while back (https://publications.lib.chalmers.se/records/fulltext/215545/local_215545.pdf), I tried my hand at implementing a program (in C#) to create ASCII art from an image. It works pretty well, but like they observed in the paper, it's pretty slow to compare every tile to 90-some glyphs. In the paper, they make a decision tree to replicate this process at a faster speed.

Recently, I revisited this. I thought I'd try making a neural net, since I found the idea interesting. I've watched some videos on neural nets, and refreshed myself on my linear algebra, and I think I've gotten pretty close. That said, I feel like there's something I'm missing (especially given the fact that the loss isn't really decreasing). I think my problem is specifically during backpropagation.

Here is a link to the TrainAsync method in GitHub: https://github.com/bendstein/ImageToASCII/blob/1c2e2260f5d4cfb45443fac8737566141f5eff6e/LibI2A/Converter/NNConverter.cs#L164C59-L164C69. The forward and backward propagation methods are below it.

If anyone can give me any feedback or advice on what I might be missing, I'd really appreciate it.

It's 2024 if I remember correctly and budgeting is a fairly common practice. Companies are obsessed with data. Yet when I got to the store and buy a videogame, dap drywall joint compount, and 3 avocados the transactions is just the store and the amount. It'd be nice if I could track what I've been buying, categories them into entertainment, home improvement, and groceries respectively.

I'm guessing this information actually is tracked but is only used for marketing purposes. But I'm curious, does anyone have more information on why transactions can't at least optionally support extra metadata about what was actually bought?

Great moment in time
What a surprise Canada has been, congratz to the Canadian fans. Odds are against them winning on their next game but here I am thinking. IMO if the game develops like that of Germany vs Spain, I think Canada has a chance. The biggest thing that is controversial is if Messi is not in the lineup. If Messi is in the lines up I see Argentina not playing as well and Canada having the upper hand. I love watching Messsi but he is not playing well, playing hurt etc., I was lucky to go to the stadium, in the Chile vs Argentina game and it's very noticeable his participation is not great though arguably one would want him in vs out. Alright Canucks let's see what you got!

When I was about 18 years old, I had a philosophy class where the teacher said this quote: "Things over which you do not have power should not have power over you." It could also be read as "control the things you control, ignore the rest".

That lesson really spoke to me. I put a lot of effort integrating it into my personality and I must say now, almost 15 years later, it made my life so much more enjoyable.

I used to get mad, really mad about stuff or get stressed about stuff out of my control, and I could never really remove those feelings. These words kept coming back to me and through some effort, I must say that I can more or less apply them in my everyday life now. It saved me a lot of trouble on various situations and has helped me break through problems way faster than I would have in the past, simply by helping me identify the things I could change and focus on those things.

I'm curious about you guys and your life stories. Has any lesson had as much impact on your life?

I picked this thing up in a Steam sale at 75% off after having avoided it like contagious illness since launch, reasoning to myself that for a cost of about £7.99 it'd still pay for itself through sheer amount of content.

And content is what I got, all right. Nebulous, homogenous, thoroughly unexceptional content. My experience has been, more or less:

• Find the three unmarked items in this room and craft them into a parcel, then deliver that to another settlement.
• Pick up and listen to countless audio tapes made by people long-dead and never particularly captivating when they were still alive.
• Boil some water.
• Read through reams of discarded notes about the daily minutiae of life in Shitsville.
• Grill some steak to go with that water.
• Slowly feel your initial interest fade as it dawns on you that this isn't a story, this is what somebody thought constituted lore.
• Realise that some people paid up to £59.99 to do this on launch day, while the fanfiction on AO3 is free.
• Struggle to see the landscape, and enemies, through the film of clown vomit that is the Gamebryo engine's gasping attempts to render lighting effects and shadows that aren't pixellated.
• Shoot at enemies who move in fits and starts, or not at all, in response to your presence.
• Shoot at them again because the lag means you can't be sure if the first shot connected.
• Question what you're doing with your life.
• Christ, shoot him again, he's still dancing. - Re-level your wobbly desk leg.
• Stare in wonderment at a game which is somehow uglier, and runs worse, than Fallout 4.
• Appreciate a passing three-headed opossum.
• Check out the pop-up for the overpriced store, which is the first thing you see every time you log in.

I thought I'd at least enjoy exploring the wilderness of a new location full of fresh landmarks, enemies and particularly cryptids (none of them yet), but I think I might've already checked out in a matter of days. I just...don't care. This is the least compelling Fallout game I think I've ever played. I can't imagine how bad this must have been on launch.

And the Camp UI is an absolutely headache-inducing abomination.

Anyway, do you think I can still get my money's worth? Can this be saved?

Are there...mods???

As part of a weekly series, these topics are a place for users to casually discuss the things they did — or didn't do — during their week. Did you accomplish any goals? Suffer a failure? Do nothing at all? Tell us about it!

Tildes is a very serious site, where we discuss very serious matters like supreme court.us, liberalism and kei cars. Tags culled from the highest voted topics from the last seven days, if anyone was a nosey parker.

But one of my favourite tags happens to be offbeat! Taking its original inspiration from Sir Nils Olav III, this thread is looking for any far-fetched offbeat stories lurking in the newspapers. It may not deserve its own post, but it deserves a wider audience!

Flesh and Blood is a trading card game (think Yugioh, Magic: the Gathering, Pokemon, etc) which only launched in 2020 but has been rapidly gaining popularity across the world.

If you’re familiar with other trading card games, this has some key differences in the pace of the games. Usually, players have limited resources to begin with, and build up resources throughout the game. In FaB, however, players start at their strongest with the most access to resources, and slowly exhaust these resources as the game goes on.

I played MtG casually for a bit over a decade, and I have a number of friends who all enjoy the Commander format. I never had the skills or budget to play in tournaments, but that’s never been my thing anyway.

I’m just curious if there are many other players here on Tildes.

If you play, which classes or heroes to you prefer? What do you think of the way the game has been managed so far? Do you play casually or are you more ambitious than that? Do you play online or do you stick to exclusively in-person games? How did you get into the game, did you play other TCGs before or is FaB your first foray?

Those urban activists who hate cars must be nuts.

Today, rather than drive my not terribly fuel efficient vehicle from my relative's house back to mine, normally an easy 2 hour 20 minute drive on divided highway, I decided to try using alternative transport.

I started out with a 45 minute walk to the highway bus station. Of course that meant carrying a fairly heavy back pack and being an old fart after awhile that got to be a pain. I spotted a Bird electric bike on my route so I rented it for the final leg of my walk saving considerable time but it cost me $8.99.

I got to the station half an hour early which meant I had the pleasure of standing beside a guy who was either drunk or just unstable. He had "All My Ex's Live in Texas" playing at full volume on his phone and was singing his lungs out. Fortunately most everyone else seemed somewhat normal.

The bus ride wasn't bad, a fairly new FLixBus with decent seats, and fortunately I didnt have to sit beside Mr. Texas. Everyone just put on their headphones or earbuds and zoned out on their phones.

But then arriving at my city, I could either Uber, which would have cost me $35, which was as much as the two hour bus ride or take public transit. After a 10 block walk to the right stop, I found the 'express' bus to my area and then had to find somewhere to buy a ticket.

Once onboard the ride was less than comfortable. The bus was not only incredibly loud and hot but the driver thought he was in Formula 1. He was pretty excitable, going hard then jamming on the brakes whenever he had the chance. 20 minutes on that bus was plenty, I can live without that pain.

Then it was another 15 minute walk to my house.

Was it fast? Definitely not. The trip took four and a half hours, almost DOUBLE the time I normally drive it in my vehicle.

Was it comfortable? Not really, no. It ranged from the hard seat of the suspension less Bird bike, to the very uncomfortable transit bus to a respite in the FlixBus and a somewhat enjoyable walk. But compared to my own car, my own music, and my own personal space, it was definitely not even close to a definition of comfortable.

Was it cheap? With the bus fare and the Bird e-bike it was about 2/3 of what my vehicle would've cost me in fuel but without the licensing, registration and maintenance, so maybe half the cost.

Was it convenient? Absolutely not. What a pain trying to figure out locations, fares, tickets and worst of all, needing a bathroom before I got on the transit bus but no place to go because every shop is locked up because of the vagrants. In a vehicle I just drive to the nearest coffee shop and buy a java to use the washroom.

Would I do it again to save money? Not a chance in hell. What an absolute pain in the ass. Slow, inconvenient, with some odd characters in my space, and not even that cheap. Never again.

Those people who hate cars must be masochists or just love hearing country songs sung badly. Ill take my vehicle every time from now on, thank you.

So I'm kind of terrified by recent political news. What can I do to help?

Options include:

• Donating
• Phone banking
• Text banking
• Postcarding
• Door knocking
• Volunteering as an election worker

Does anyone have an informed opinion about which of these will actually move the needle and which ones just make you feel like you're doing something?

Basically the title. I think I've come to accept that as basic as it sounds, this is one of my favorite genres.

The issue I frequently run into is that so many of them are designed around PvP and / or Co-Op. Like ARK, I love the idea, but most of the mechanics are for PvP servers, which I have zero interest in.

Funny enough I'm not too into true survival games (Green Hell, The Forest), as I kinda enjoy the whole "Combine iron with two sticks and make an automatic weapon" progression of other games in the genre.

Obviously I've played Minecraft & Terraria, but also Subnautica, Palworld, Satisfactory (sort of counts), and NMS and enjoyed all of those.

Project Zomboid seems like it has too steep of a learning curve for me to get into.

I tried Astroneer, but the utter lack of base building and organization drove me up the wall.

EDIT: Forgot V Rising, which I also enjoyed solo, but it's definitely built with a PvP server in mind, which kind of makes progression in solo feel like you're aiming for a goal that doesn't exist.

I appreciate everyone's suggestions, I think I may give Raft or Project Zomboid a go.
