I built my own equation editor around a slightly different workflow — what is it missing?

I’ve been working on my own browser-based equation editor, designed primarily for desktop use.

I’m obviously not claiming that equation editors are a new idea, there are already plenty of good ones. My goal was to build my own version around a simple workflow: create an equation quickly, then move it into whatever application or format you actually need.

A few things I thought could be useful:

  • You can search for individual mathematical symbols, but also for complete equation templates. For example, instead of building a quadratic formula, Fourier transform or Taylor series from scratch, you can search for it and insert an editable version directly.
  • Once the equation is ready, you can copy it as plain text, Unicode, LaTeX or MathML, export it as SVG or PNG, or generate a link to share it with someone.
  • Everything is saved locally without requiring an account, and there’s an accessible history in case you want to reopen or reuse an equation you created earlier.

Here is the editor:

I’d be really curious to know what you currently use and what still feels frustrating or unnecessarily slow in your workflow.

And if you have any ideas for features, templates or export options that would make it more useful, I’d really love to hear them. I’m still actively improving it, and it would be great to build some of the ideas suggested here.

Apple Developer enrollment rejected after weeks of support with no explanation

I'm hoping someone here has some advice because I'm honestly stuck.

A few weeks ago, I started enrolling in the Apple Developer Program so I could publish an app I've been working on. I paid for the enrollment, but it remained stuck in a pending state. After contacting Apple Developer Support, they told me there was an issue on their side related to the enrollment process and asked me to re-enroll using the Apple Developer app.

From that point on, I spent weeks going back and forth with support. I followed every troubleshooting step they requested, sent screen recordings, identification documents, device information, SEID, and anything else they asked for. The case was eventually escalated to a Senior Advisor and then to Apple's operations team.

After waiting several more weeks, I finally received a response. The entire explanation was:

>

That was it.

No explanation of what the issue actually is. No indication that any information I provided was incorrect. No appeal process. No alternative path forward. Nothing.

What makes this especially frustrating is that I've already invested significant time and money into this project. I've spent weeks developing the app, purchased Apple hardware specifically for development and App Store distribution, and fully cooperated with every request from Apple Support.

At this point, I'm not even asking for approval. I simply want to understand what the problem is and whether there is any way to resolve it.

Has anyone here gone through something similar? Were you eventually able to get a real explanation from Apple or find a way to escalate the case further?

Any advice would be greatly appreciated 🙏

Engineer considering a full migration to Obsidian: worth it?

I'm an engineer and currently my notes are spread across several tools: OneNote, Word, Notepad, and Notepad++. I use them for meeting notes, learning new technical topics, writing summaries, documenting issues, keeping logs of my work, and generally storing information that I may need months or even years later.

Lately I've been hearing a lot about Obsidian. It seems to have a very enthusiastic community, and many people describe it as a game changer for knowledge management.

I'm seriously considering migrating everything to Obsidian, but that would represent a significant amount of work. Before committing to such a transition, I'd like to understand whether it's really worth it.

For those of you who switched from more traditional tools such as OneNote, Word, or plain text files, what convinced you to make the move? What benefits did you actually gain in practice? What does Obsidian allow you to do today that you couldn't do before? Looking back, was the migration effort worth it?

I'm particularly interested in hearing from engineers, developers, researchers, or anyone who works with a large amount of technical information and is constantly learning new things.

Thanks in advance for your feedback :)
