How do you try it out in the web browser? There's no obvious link on the website
GlebShalimov•2mo ago
I haven't published the web version of the app yet, maybe I will in the future
cdfuller•2mo ago
Your description above says it's a supported platform FYI
GlebShalimov•2mo ago
Sorry, my bad
leni536•2mo ago
At the meantime (not mobile friendly): https://www.chiark.greenend.org.uk/~sgtatham/puzzles/js/pegs...

It is part of Simon Tatham's puzzle collection, it also has an app on F-Droid:

https://f-droid.org/en/packages/name.boyle.chris.sgtpuzzles/

And the sgt-puzzles package on Debian/Ubuntu, possibly other distros package it too.

domlebo70•2mo ago
Interesting name
GlebShalimov•2mo ago
Thank you
sim7c00•2mo ago
curious
GlebShalimov•2mo ago
The name Pegma is a play on words that combines: "peg" (peg, token) is the main element of the game and "theorema", which is associated with mathematical rigor and logic
sim7c00•2mo ago
cool, thanks a lot!
InsideOutSanta•2mo ago
That name makes me slightly upset and afeared. The game looks nice, though.
GlebShalimov•2mo ago
Why?
tecleandor•2mo ago
There's certain sexual activity called pegging. I guess that's what could come to mind here :)
GlebShalimov•2mo ago
Oh, I didn't know
abcd_f•2mo ago
There's also smegma, which is not a whole lot better.
Tade0•2mo ago
It appears that every short word means something obscene in some language.

Advice would then be to avoid short names for products altogether.

GlebShalimov•2mo ago
I agree. I wanted to add something short and creative

Mitsubishi renamed the Pajero in Spain, because "pajero" means "wanker".

rlv-dan•2mo ago
Honda Jazz was first called Fitta which is cunt in Swedish.
InsideOutSanta•2mo ago
It reads like a portmanteau of pegging and smegma. Hope that helps, although I'm afraid it will do the opposite.

For people living in Germany, we already have a similar problem with Figma

GlebShalimov•2mo ago

junon•2mo ago
Yes, the intent is very clear.

EDIT: It seems based on other comments you are genuinely unaware of how it sounds, which is totally fine - I feel someone should let you know it sounds like "peg me" or "smegma", which uh... well, ask an LLM what they mean, I suppose. I don't particularly want that in my HN comment history. :D

GlebShalimov•2mo ago
Thanks for the explanation
leni536•2mo ago
Requires google play to run :/
GlebShalimov•2mo ago
And what other platform should I add? The application is available in RuStore https://www.rustore.ru/catalog/app/com.khlebobul.pegma

AlecSchueler•2mo ago
I know this ship has probably sailed but the LLM cover text still feels off-putting to me, like you haven't considered my needs as a reader. I come away at the end with a feeling of "what is the project actually worth to you if you can't spend 5 minutes describing it?"

For example, saying "code available on GitHub, inviting community contributions and transparency." I know what GitHub is, I understand the benefits of having it there, it's just a waste of brain power to read the rationale written out in this way.

Similarly "Custom-designed font created by the developer to enhance the game’s unique style?" Ok, that's great, but do I really care about that specific detail? It sounds like there was a conversation with an LLM and then a request to regurgitate the information into marketing speak, without any consideration for the actual needs of the people being marketed to.

Again, I know I'm probably increasingly alone in this and I'll have to just get used to it, but as a lover of writing it feels like watching a tragedy play out in real time.

bitwizeshift•2mo ago
You definitely are not alone in feeling this way, it’s happening everywhere now and it’s driving me nuts too.

I have the same complaint at work, where coworkers are using it for writing pull request descriptions, and it pumps out slop buzzwords like “streamlined the documentation”. Like, you didn’t streamline anything, you ran prettier on a markdown file!

On top of this type of description being useless marketing jargon, the writing style risks to train future LLMs to devolve their writing styles further into this. More frighteningly, how long until the excess amount of LLM-generated slop text like this starts training future humans reading it? People tend to model how they speak off of what they hear and read, and it’s everywhere now.

pmontra•2mo ago
> how long until the excess amount of LLM-generated slop text like this starts training future humans reading it

Not much. Add to it deference to technology and the innate preference for new stuff not liked by previous generations: sloppy LLM style will look more authoritative than well thought human style of parents and older siblings.

GlebShalimov•2mo ago
ok
GlebShalimov•2mo ago
ok
endemic•2mo ago
I was hoping to be able to play on the website! Do games like this need a native app?
GlebShalimov•2mo ago
Why not?
endemic•2mo ago
Different audiences, I guess. I know lots of people _only_ use dedicated apps. For me, the friction of needing to search an app store, then download in order to play, is too much. I'd rather click/tap a link and be able to start playing.
GlebShalimov•2mo ago
Fortunately, Flutter provides this opportunity. Maybe I'll make a web version later
