Economically sustainable and ethical monetization of user-generated-content games. The closest most known example of this kind of game nowadays is Roblox, but I'm thinking of things more like Mario Maker or the older-generation Atmosphir/GameGlobe-likes. Unlike "modding platforms" or simulators/sandboxes/platforms such as Flight Simulator, VRChat or ARMA, these games' content are created by regular players with no te…

My favorite Microtransaction systems are in Counter-Strike Global Offensive and Planetside 2. Planetside 2 has very slight pay to win mechanics in the form of subscriptions for more xp, but it doesn't feel bad to play without pay. Counter-strike on the other hand (and I think so other valve games too) have just about the perfect model in my mind. There are no advantages you get by paying, only status. The skins that…

That is indeed my current conclusion of the least-ethically-bad viable monetization. Purely cosmetic.

However, paid status is not really a big hook for single-player games, you need to be able to show it off! This means that the game must be designed primarily around multiplayer interaction, which is fine but limits a lot the kinds of games you can implement with this monetization.

I have a pile of mp3s and want to splice them together with a single ffmpeg operation. Essentially injecting multiple small audio files into a large one using time codes. I know there's got to be a way to do it, but I have yet to find a way to do it in a single operation instead of multiple passes.

ffmpeg -f concat -i mylist.txt -c copy output.mp3 https://superuser.com/questions/587511/concatenate-multiple-...

It's not quite so simple; I need to insert smaller audio files into a larger file at specific time codes.

Some god awful combination in a complex filter using atrim to pull the pieces, adelay to set the positions in the output, and amix to put all of the output back together could probably do it. What that command may actually be is definitely open but that's probably the only way that would work as otherwise this is really 2 separate operations (chopping then merging) so there isn't going to be consideration for having…

I'm very fine with command soup; the plan was to generate it with a script and run it directly. The input files are in a lossy format so I'd rather avoid having intermediate WAVs or double-encoding or something like that.

I'm surprised you didn't mention Core. https://www.coregames.com/

Yeah the post was getting a bit long, there are a bunch of similar games to the ones listed, I just used one of each to exemplify each strategy.

Core is very similar to Roblox in that the creation tools are rather involved, it tends more to a platform with distinct creator/consumer roles.

There's also the PS4 game Dreams, as well as other integrated-modding initiatives like in Krunker.

I want to bring back old school distributed forum communities but modernise them in a way that respects attention and isn’t a notification factory. Mastodon is a pretty inspirational project but the Twitter influence shows, I miss the long form writing that was encouraged before our attention spans were eroded. Not at all close to solving it, but it’s been on my mind for a long time. Would love to hear if there are o…

Is this a software problem? There are a lot of open sources (with their differences) platforms. From old forums, to more modern, etc. I think the problem is that people don't want or don't know how to use a forum. This is based in my experience: - Old people: They started to use internet recently so they are used to social networks (Facebook, Instagram), and newspapers websites. - Young people: Hard to make them use…

If you think young people won't use forums, you clearly haven't seen Scratch's. (https://scratch.mit.edu/discuss/)

Splice you parent file at the time stamps, interleave the samples, then concat.

I'm trying to make social media moderation more democratic and using that to decide fuzzy questions like "should this post be censored", or "is this misleading" [0]. While the crowd's answer won't be perfect it will help sort through a lot of the noise and feel better than the decision of whatever mod happened to create the subreddit. The problem: how can I make decisions based on a sample with a binary question. I t…

This might be a good use-case for the "bayesian truth serum" http://economics.mit.edu/files/1966 This applies when our questions are not just trying to learn about the world (e.g. 'Our survey discovered that 10% of posts are considered misleading'); we are going to use their answers to decide on actions , e.g. removing posts, attaching warning labels, etc. Those answering the questions know this, and (if they have a…

How does this avoid (or compensate for) downweighting the preferences of people who are legitimately ignorant about what everyone else thinks (and consequently give estimated distributions that hardly match the real answers at all)?

We are working on a totally new way to do cold fusion, our only problem is getting enough new fuel into the reactor without disturbing the running process. Any help would be greatly appreciated.

Disclaimer : I know nothing about anything. Hawking radiation ? Laser tunnel ? Magnetic canon ? Centrifugal launcher ? Vacuum diffusion ? Electrical beam lensing ?

> Hawking radiation ?

That actually does make for a fairly efficient (better than fusion in energy per unit fuel mass) reactor design in principle, but you need a sub-solar-mass black hole (in the 1 billion - 100 billion ton range), and there's no known practical way to produce one.
