SpudFiles

I think this is probably LLM-generated spam that's trying to get a backlink for SEO purposes. They haven't logged in again since posting, they link to a commercial site for no good reason (the specific computer doesn't matter here), they absolutely butcher the GGDT acronym, and their post feels ...

This question is answered by John Corner's 1950 book "Theory of the Interior Ballistics of Guns" in section 9.16 titled "The maximum possible muzzle velocity". The equation in the second explanation is one of the equations given by Corner (two different derivations). So yes, the speed of sound ...

PCGUY: On the subject of forum speed, SpudFiles has been pretty slow lately, presumably due to the large number of LLM scraper bots. I run a couple of forums myself and until recently had problems with bots slowing the forum down or even taking it offline. I've had great results running Anubis ...

I don't know how many people would use it, but I would find it useful. I've been developing a new pneumatic gun simulator. In my old notes for my previous simulator, I had quite a few links to threads on the SpudTech archive that are no longer online and not on the Internet Archive Wayback Machine ...

Are there any plans to bring back the SpudTech archive? It was useful from time to time.

BlasterSim is adiabatic.

Sorry for the delay, the email notification didn't come in until today for some reason.

BlasterSim is my pneumatic and spring gun simulator. I've been slowly developing this since last year and have decided it's finally ready for a wider release. Please note that the software is still under development and its documentation in particular is incomplete. However, the core functionality ...

To get more specific, static friction matters when the projectile mass is low (like with Nerf darts) because it allows the pressure to build up before the projectile moves. If the projectile mass is low, then the projectile might move a lot initially, which would keep pressure lower for the duration ...

There definitely are a lot of bots on SpudFiles, though few seem to be posting anything at this point. They seem to mostly be accessing the forum, slowing it down a lot if not bringing it down entirely over the past few days. PCGUY, I'd recommend blocking many of the worse behaving bots with robots ...

Thanks for making the new tool. I haven't had much of a chance to look at it yet, but I wanted to make a quick comment as SpudFiles has been down more often than not lately. On that note, it might be worth putting some contact information in the spreadsheet itself so that you're not so reliant on ...

You can definitely run JavaScript in a web browser locally without a web server. Many programs today also are written in JavaScript but basically embed an entire browser with the program, so the user doesn't notice that it's not native.

I'm not so sure about WebAssembly. I think Chrome doesn't like ...

Good points. If you want something that doesn't require installing any extra software, JavaScript or WebAssembly would be better choices than a spreadsheet. It would be neat to have a webpage that does the simulation. It would be completely cross-platform. You could even run on your phone! It would ...

It's your choice, but I'd recommend against using a spreadsheet for anything nontrivial. Debugging and testing spreadsheets is far too difficult. Actual code is a much better option. I might make a prototype of something in a spreadsheet, but for any "production" software, code is a better choice ...

All, I haven't participated in this community for a while due to other time commitments. But I know there are a number of people who build water guns here, and I'm running a survey for one of my websites about ...

Nice work. What is GALE? I'm assuming it's a code you wrote, but I could be mistaken.

How do the various codes compare against any measurements you've made? This sort of validation is really important if we want to understand how to make better launchers. I think if this comparison was done, you ...
