I am out of the loop. Is Next.js "the future" and something I should consider adding to my knowledge pool?

Browser Based Document Recognition
Are you able to use a OCR library in the browser? Here is one I found

what is the best package to read text content from a pdf in js?
But keep in mind, PDFs can be fully or partially made of images, and if you want text out of those, you will need to OCR them. There's tesseract.js for that.

Can anyone comment on the state of the tech or recommend a package that can convert an uploaded photo of handwriting into text ?

Extract information from image into JSON
YOu could try using tesseract.js to OCR the images. Though might be a challenge to figure out the times/days of the classes.

WebDev Recommendations to Mimic AWS Textract Demo Functionality
I've never used it - but Tesseract.js looks interesting. Perhaps you can use it as a foundation on which to build something like the AWS tool (which seems to work by overlaying an SVG over the top of the image, then manipulates that SVG when user clicks on a results tag to get the word/phrase's highlight box to display)?
- Can I use OCR to recognize text and then paste its contents elsewhere?

How to implement invoice OCR on React Native
I tried researching a little on this topic, so from what I understand to achieve this feature, I would need a library that supports Optical character Recognition (OCR) such as Tesseract.js or Google ML Kit to do it. However, I'm not too sure if these libraries will be supported on React Native apps.

Word Quake - write words, avoid the shakes, powered by Tesseract.js
It's definitely one of the best for on-the-fly OCR, but I think a server-based implementation using Google's Vision API would be way better. Definitely not mine, the AI used here is way beyond my skill level - link: https://tesseract.projectnaptha.com/

JDK 21 - Image Performance Improvements
Is there any fast way to get pixel values and pixel coordinate? I had to jump through a lot of hoops to get convert BufferedImages into a format that's useful for image processing it to be a reasonable speed in BoofCV. getRGB() is glacial. At one point I was trying to convince the JDK team to make private data structures public again. Right now it's inconsistent what you have access too.

The Ancient Secrets of Computer Vision
I will take the opportunity to call out one of my favourite libraries, BoofCV (http://boofcv.org)
It comes with a wonderful demonstration tool that allows you to apply the various included algorithms to images and tweak the parameters in real-time – including the Hough transform. A great tool for helping to understand how these kinds of algorithms work!

Good Open Source Repositories that Accepts New Contributors
Speaking of using the vector api, I see there's a class in boofcv that converts rgb to hsv. I've previously written a simd accelerated version of rgb to hsv using the java vector api. For anybody looking to do a bit of code janitor work, converting the one-off library into something that could be contributed to /u/lessthanoptimal's project might be a worthwhile contribution.

JavaFX .jar (from clojure) won't find "glass" when run via `java -jar`
For instance I looked at BoofCV and all I found was : https://github.com/lessthanoptimal/BoofCV/issues/265 " the question now seems to be can you compile the library as native. The answer is probably but someone needs to try it."

Feedback Requested on Updated BoofCV QR Code Tutorial
There really is a community for everything on Reddit... Anyways, so I've updated the tutorial on QR Codes in BoofCV. If you're not familiar with it, BoofCV is a computer vision library that also includes a high quality QR Code scanner. Plenty of benchmarks and examples can be found on the website to back that up. Here's a link to the tutorial page and please let me know if it all makes sense. The tutorial focuses on applications which are either command line or have a GUI.
