Why #Apple is on top quadrant? Apple might look not even playing the AI sports, is silently producing best affordable devices for running a local model for personal purpose. If you disagree, try Gemma 4 which released today on a Mac mini and try any alternative, future is clear.

Why #Google is on top quadrant? #Gemma has become the best in class Open models that I've been running for months on my pc. Google made it to #1, from producing totally useless to, the best open models in less than a year. Previously Meta had this spot, followed by Alibaba.

Grew up reading #Thirukkural 2000-year-old #Tamil #poem that pack entire ideas into just two lines. So I built #KuralBot to see if #AI can learn this art. Users give a meaning. AI writes poem. Community votes. AI retrains. It's rough but getting better kuralbot.com

@AiPa1442 @blind_via I design PCBs as hobby, mostly learn from experts here. Sure soon AI will design better than me, but as I learn, I realise it’s more art than just connecting & packing components. Same is true for software design. AI solves 75% of work but rest 25% is where the art goes

@zain_kh_ Valetudo works on top of the manufacturers firmware to replace the cloud features of the manufacturer. My stack tries to replace the firmware part and makes it more hackable

@zain_kh_ My plan is to directly support Valetudo for the end user UI and interactions. What am building is an entire SLAM firmware stack, everything that Valetudo does not replace on the commercial vacuum cleaner models that it supports.

@DineshM My article mentions ADB port open just by plugging in usb. The actual security issue is around device running rtty. It’s a Linux device with ADB installed

#ReverseEngineering is so much fun. My #Robotic #VacuumCleaner is now running firmware SangamIO written in #rustlang Guessing each bit & their sensor source seemed impossible. Finally decoded data to get full visuals github.com/codetiger/Vacu… Implementing SLAM algo is next task

@AltMenM Hi, to start with, use Wi-Fi segmentation. Create separate Wi-Fi ssid for iot devices. Then some routers have options to monitor and block IPs that device is connecting to. I shall write more info in my next article
