I want to learn-in-public making an interpreter for my fellow C students.

I've been working on an incremental brainfuck-and-beyond interpreter. Brainfuck is nice because you can deal with single characters rather than lexing or parsing. Right now it's just a brainfuck interpreter with all the bells and whistles you'd want animation, highlighting the loop you're in, skipping the loop you're in, memory tape visualizer, decent error messages when you write a bad loop. Here's a preview (kinda ugg because everything has to live in one file) https://ellie-app.com/nG99JJ3wt6da1

I'd like to make a bit of a writing series on this: start with BF with one instruction and a single cell tape. Expand to cover everything in BF. Then expand out to a language slightly bigger until we have the idea of scopes being a thing.

Here are the ways I was thinking of expanding the language a bit in order to bring in new concepts:

- Bring in numbers where 10> means >>>>>>>>>>. This means we need to parse more than one character at a time and introduce new ways of failing. Like maybe 5[ is a bad instruction because we don't want to have a loop in there 5 times (or maybe we do?)

- Add variables. I know that sounds antithetical, but I think it's interesting. Programs like "++^var>_var" would mean "increments the value in the current cell twice. Store that value into a variable named 'var'. Move one cell to the right. Put the value stored in 'var' into the current cell" so then we have to keep track of what variables are what. Kinda fun.

- subroutines or even better function calls so that the current scope of variables can change. I have no idea what that would be like.

Anyways, is there anything like this out there already?

I'm working on https://apispire.com - APIs as a service (authentication, mail submission etc..) nothing fancy.

I have to finish the front end but I don't like to do it so I'm constantly procrastinating.. Funny is that I wrote the backend in nodejs, later in .Net, and at the end with golang but I never finish the frontend...

I am working on an application designed to keep runners motivated: https://www.frenzyrun.com The main features include: - Capture the flag: Every week, a virtual flag is planted randomly in various cities. Capture these flags to collect virtual coins, encouraging you to discover new areas. - Virtual medals: Earn medals by running iconic distances. These medals will boost your experience. - Groups: Compare your perfor…

What cities are supported? You say various cities, so I assume just the top 10 or something

Is it too developed if it’s in private alpha? Anyway … I’ve been working on CodeApprove ( https://codeapprove.com ) for a while because I think code review is the biggest shortcoming of GitHub. The idea is to make a code review tool for power users. Just like you have an editor that makes you productive at writing and reading code, you should have a review app that makes you and your team productive at reviewing it.…

I agree that a better tool is needed! I like all the improvements you are selling the tool on, but one of my biggest gripes with code review experiences has been the inability to specify the ordering of the files in the diff. Most people look at the diffs from top to bottom by default, and I sometimes have my questions answered when I move down in a diff. It would be so much better for the author to be able to select an order.

Good luck!

https://pastmaps.com Been working on this as a new way to find, explore, and view old historical maps and aerials of my area. Still heavily in development but have been surprised by some early traffic stats (1-2K organic uniques / mo and growing 200%+ m/m right now) Hoping to add in more advanced map tooling within the next week or 2, including new basemap options, 3d terrain view, and then a proper search box which…

Your site is similar to https://www.oldmapsonline.org/ I have found the ui for map difficult to use in the past.

Yea I used to use this site quite a bit but it is clunky as all hell. I found myself cobbling together my own tools or stitching 3-5 different resources together over time for my research and this eventually just led to me starting work on Pastmaps. I'm hoping I can build something far more comprehensive, modern, and intuitive

This is really cool, makes me nostalgic for a lot of time georeferencing random maps from the library of congress or from municipal archives etc. In that same vein, you could add a feature where users could contribute georeferenced map files for community review and approval--I think that would really increase your scalability. I see you have an email for that currently.

I love love love this direction. And yea, I have a basic email but I really think a super simple upload and maybe even dead-easy georeference tool for folks to contribute data is a no-brainer! I'm bumping this up on my backlog, thank you!
