Show HN: AppMaker – Build business apps with AI, visual editing and code

https://appmaker.io/

Hi HN,I've been working on AppMaker, a tool for building with AI business apps like CRMs, dashboards, and internal tools. It is NOT a low-code.https://appmaker.ioApps come with a database, authentication, and backend logic, and can be exported as standalone Node.js applications.It's still in beta, and I'd love to hear your feedback.

Show HN: AppMaker – a visual JavaScript app builder

https://appmaker.io/

I’ve been working on AppMaker, a small experiment in visual app development.It has a visual UI builder, JavaScript on both the client and server, a built-in database, and lets you download the generated Node.js app.It’s still early, and I’m especially curious about one thing: In the age of AI coding tools, is there still a place for this kind of structured visual development...

Thanks a lot for the thoughtful feedback, really appreciate it!

360: Do I look like a leader you'd want to work with?

I’ve spent 20+ years in tech, with 15 of those in software leadership. Recently I decided to look for a new opportunity, and as part of that I’ve been sharing some of my lessons and reflections on LinkedIn (where I have ~7800 followers) and a small about me website.I’d love a kind of “virtual 360” from this community: based on how I show up, do I sound like the kind of leader you’d want to work...

I still believe those early 8 bit computers were great to introduce young people to coding. These days we have many options but also lots of distractions. At one point I tried to replicate that coding experience in a browser by implementing codeguppy.com -- I think I had partial success... What do you think?

Show HN: I recovered one of my earliest ZX-Spectrum games from an audio cassette

Recently, I managed to recover some of my earliest work from the ZX Spectrum era from an old audio cassette.It is a mini-game, that I created as a teen, called "Atomix," written in BASIC with a mix of Z80 assembly — some of which I coded myself, while other parts were disassembled from existing games. I put the game in an modern emulator and recorded a screencast. See the video in my linkedin...

Re:Ask HN: JavaScript with Begin End on Wednesday January 22, 2025 @09:59AM (#42793505)
Thanks for the comments! I know that is a little bit verbose but so tempting seeing that sometime young coders have hard time with {}. I'm concerned though with "unlearning" this trick once they are ready to switch to regular JavaScript.

Ask HN: JavaScript with Begin End

Hi coding enthusiasts,I run a small JavaScript coding site for code newbies: codeguppy.comWhat I've noticed is that most beginners have a hard time to properly open and close the { ... } for functions, code blocks, etc.I was playing with the idea of introducing a simpler "javascript" to codeguppy.com -- where basically the symbols { } are replaced with begin ... end.A simple pre-processor will...

Re:Do we have gender discrimination in elementary schools? on Monday September 04, 2023 @03:33PM (#37384070)
Having a separate boys club and a girls club would be an acceptable solution.

Do we have gender discrimination in elementary schools?

When I found out that there are coding clubs in US public elementary schools that accept only girls, I thought to ask reddit about this. In my opinion children of both genders should be allowed equal access to (coding) education – especially within a publicly funded educational system.To my surprise I got a lot of comments on my reddit question defending the school position.What’s your opinion...

Hi there -- This is Adrian, the author of the course and codeguppy.com platform. First of all: thank you very much for your feedback.

As of now, the course has 693 slides and covers also more advanced concepts such as closures and classes.

The intended audience for the course are teachers ... but independent learners (especially those interested in p5.js) may find the course useful as well.

I love the old Usborne BASIC books... and the old type-in BASIC program books. I have in my collection a few of those. I love the work of Jeff on converting those old games to JavaScript.

As I mentioned, I'm also impressed by the old Usborne books, therefore I also tried recently to create an illustrated JavaScript course in that style ... See here the first 30%:

Re:Illustrated JavaScript coding course [pdf] on Saturday May 13, 2023 @12:26AM (#35925504)
To add a little bit clarity to this post.

I started working on a new illustrated coding course/curriculum for JavaScript (slide deck style).

I’m about 30% into the project ... and would like your feedback.

Please see below the first lessons: https://codeguppy.com/site/download/coding_course.pdf

If you get the chance to download and review the file, please let me know your opinion/feedback.

The difference is that coralmicro will run on modern hardware (e.g. small SBC similar to raspberry pi)
Thank you for the comment and suggestions. I'm not very familiar with Lisp... so I was considering an imperative language with easy to learn syntax: javascript, lua, or python.

Ask HN: What software stack to select for my project (a modern retro computer)?

Hello all,I need your advice in selecting the software stack for an educational, boot-to-code computer. The computer will be an AIO with a keyboard, screen and a Linux board with just-enough CPU to run the coding environment.The intent is that eventually in the future to turn the computer in a commercial product that will come bundled with a coding book that will teach coding to young audiences...
