We're working towards Tiptap v4 🚀 Join the discussion on GitHub if you'd like to contribute; everyone is welcome ❤️

Tiptap@tiptap.dev

This week, we officially started working on Tiptap v4. The idea hub on GitHub has been open for a while, and every contribution helps us shape what v4 will become. We'll keep v3 in maintenance mode but won't add new features. github.com/ueberdosis/t...

A must read from my buddy @bdbch.com –core maintainer of @tiptap.dev bdbch.com/blog/prosemi...

‪Imagine spending eight fkn thousand dollars for the MBP and not getting the fucking AC adapter 👏🏻 who’s brilliant idea was this? “it’s because of the carbon footprint” but I have to buy a separate fkn box to get the fkn adapter to be able to charge my 8 fkn thousand dollars MBP. (chef’s kiss)‬

Wow! This is crazy 😱 it’s my first ever GitHub sponsor for my work on open-source ❤️ I cannot express how grateful and happy I am about this milestone 🎉

Same prompt, xAI, OpenAI, and Gemini, which one looks the best?

Also, xAI was by far the fastest model to output the image, and OpenAI was the slowest one

Also, GPT Image 1.5 was the most expensive one, Gemini PRO after, and then xAI as the cheapest one :)

Same prompt, xAI, OpenAI, and Gemini, which one looks the best?

Worth mentioning that the only one that supported transparent backgrounds out of the box was OpenAI, for Gemini, I had to craft an erosion tool to erase a magenta background, which didn't even come as a single color but in a range 🫠 For xAI maybe I forgot to configure something

I asked for image generation AI models. A random person came in telling me that I should hire an artist, I just replied it’s just to prototype and I’m not hiring any artist just to prototype and I got blocked? 😅 guess people have a very thin skin

What are some good AI models for image generation? I’m working on a game asset generation platform for myself and I’d like to test different models beyond NanoBanana and GPT :)

Pixel art still has some artifacts, but I think this is due to Gemini itself not creating proper pixel art, because it's creating giant "pixels" in a much bigger image canvas, so that's why it's not looking that good, and I'm getting artifacts. Also, my erossive script is maybe a little aggressive 😅

Wow, check this out! The background removal looks sick when it comes to hand-drawn art style 😱

> Style: Hand-drawn. 2.5D-style armour for a Diablo-like roguelike game. The armour should resemble a demon. You can take inspiration from Diablo's demon hunter and World of Warcraft rogues. Standalone item draw. No character. Avoid: blurry, low quality, poor quality, characters, enemies, npcs.

A fun project that I did over the weekend when my wife and baby were napping, even though I promised myself I would not touch the computer on the weekends 😅 It's an AI tool to generate game assets. Since lately I've been playing around with @phaser.io and @godotengine.org but I'm not a graphical...

Gemini to generate the backgrounds with this particular #ff00ff shade", and you know what? Gemini does not give a F$c# about the hex you tell him and it generates a different shade of magenta, so you gotta due hue-based magenta detection across the sprite to identify the magenta shades and then...

proceed with the removal of those. I'm learning a lot with this project and burning quite a few tokens and quite a few dollars in asset generation with the Gemini API, but hey, knowledge has no price, unless it ends up getting me broke. At that point I wouldn't care because my wife would 🔪 me 🫠

and the result ended up very promising, but as you can see from the screenshot, there are still pink/magenta artifacts remaning from the image manipulation, because Gemini does not generate real transparent backgrounds, it lacks of alpha channel outputs and I had to manually do it myself after...

receiving the output. But there's also another catch, usually in game assets, designers have this accepted pattern of using this particular shade of magenta #ff00ff to symbolize transparency. It's wildly used as it's a color that's not used at all in game design so I told myself "ok, let's ask...

artist I decided that "why not try to build my own asset generation pipeline using Google's NanoBanana so I can prototype something more appealing than colored squares?" and there's the result. I've been slowly iterating on generating sprites and spritesheets that allow for transparent bgs...

Hey @bsky.app I think the OG is broken only here because I’ve been testing on other apps and OG testers and works fine, could bluesky not processing the URL correctly?

npmx.dev/package/@cur...

Hey @npmx.dev what am I missing on my package to have a better looking OG generation? 🤔

And somehow my package gets redirected into a blank page 🤔

Well, there's even docs about it now! Check them at graphdb.alexvcasillas.workers.dev I've used @cloudflare.social pages and workers and @astro.build to quickly get the docs up and running!

Alex Casillas@alexvcasillas.dev

Do you remember this one from yesterday? Well... we now have @graphdb/core at 2.0.0 with lots of improvements, fixes, breaking changes, and lots of great things and of course @bun.sh first 🔥 You can check the repo 👉 github.com/alexvcasilla...

What are some cool side projects you have that you are proud of? I’ll start with a couple of mine and with my latest www.curl-runner.com

This one is a memory monitor that I’ve build for some memory intensive side projects github.com/alexvcasilla...

This one was my take on an in-memory database github.com/alexvcasilla... and I’ve always think on coming back to it but use @bun.sh and offer a nice CLI or even TUI

Another thing that I’ve done to try to see if I could squeeze all of @bun.sh performance was github.com/alexvcasilla... a Redis-like server built with Bun and the results were impressive, hand on hand with the real Redis server!

This was my take on a CDN over NPM github.com/alexvcasilla... as an unpkg alternative. I wanted to try Cloudflare caching and it turned out really great, though I’d not use Next.js anymore if I had to build this again from scratch and rely on @bun.sh and Elysia

Wow! @npmx.dev looks amazing, it has so much information than regular @npmjs.bsky.social and looks very clean and fully featured ❤️

The other day I posted this on X and I thought I could also share it with y’all here, maybe you also like it ❤️ I was trying @phaser.io and reproduced Pokemon Fire Red :)

A live collision editor, a live trigger editor, a live grass editor, a live dialog editor, and the debugging menu because I want to be able to edit collisions and triggers and grass and others while playing the game instead of going back and forth and figuring pixels in my head 😎

And the prof Oak lab with dialogs and triggers ❤️ what do you think? 😊

Some more gameplay, which I ended up very satisfied with 😎

Cool side project from my friend @bdbch.com here! Follow him if you’re interested in more updates and see how it goes, he’ll be sharing more soon 😎

More progress today. Pumped out a few lines of code yesterday and got the feed working now. It's not perfect, the header is to big, the page is not scrolling up, the search is flakey but we're getting there. Going to fix bugs today and then continue onwards to sub-pages & the home feed + feeds.

Will I be able to read and understand this when I come back later? Maybe not in a year, maybe tomorrow 🤣

Today I did something crazy. Some context: I’m a mess and I had my ~/ dir scattered with projects without any criteria nor order, and today I felt like I needed to tidy things up, so I asked Claude to go through my ~/ and move everything into ~/code and then categorize everything [1/2]
