Magic Cauldron: Harry Potter Themed Gender Reveal Party - #Aurdino
Earlier this year, we had a very fun filled Harry Potter themed gender reveal party. For the reveal, I built a Magic Cauldron which would reveal the gender. Check it out for yourself! For this I needed: A Cauldron. WS2812B LED array. Aurdino UNO. Bread board and jumper wires. Dry ice. Kasa Smart bulbs I will go over in the following sections The Mist.
Kakashi: The Copycat Robot - #Aurdino #image processing
In this post, I want to share about "Kakashi: The Copycat Robot"—a fun side project I built a few years ago. The name is inspired by the famous character from Naruto, Kakashi Hatake, also known as the Copycat Ninja.The goal of this robot was to mimic Kakashi's ability to copy movements—though, of course, in a more limited way. Check it out for yourself!Here are the things I used to build
Neural network inference pipeline for videos in Tensorflow - #Deeplearning #Tensorflow
Just as we saw a huge influx of images in the past decade or so, we are now seeing a lot of videos being produced on social media. The need to understand and moderate videos using machine learning has never been greater. In this post, I will show you how to build an efficient pipeline to processes videos in Tensorflow.  For simplicity, let us consider a Resnet50 model pre-trained on
Finding Where's Waldo using Mask R-CNN - #Deeplearning #ML
When I was a kid, I really loved solving Where's Waldo. There were few books (it used to be called Where's Wally) in our school library on which I spent hours finding Waldo. For people who do not know what it is, basically Waldo - a unique character is hidden among hundreds of other characters and you have to find him in all the chaos in the image. Now that I am too old to be solving it and
Higher level ops for building neural network layers with deeplearn.js - #Deeplearning #javascript #ML
I have been meddling with google's deeplearn.js lately for fun. It is surprisingly good given how new the project is and it seems to have a sold roadmap. However it still lacks something like tf.layers and tf.contrib.layers which have many higher level functions that has made using tensorflow so easy. It looks like they will be added to Graphlayers in future but their priorities as of now is to

Unfortunately the process com.android.phone has stopped in CM 13

I have a good old nexus 4 still trying to keep up with the big boys in the market. After google ditched the plans of releasing the latest android 6.0 - Marshmallow for nexus 4, things didn't look so great. But with the release of CM 13 (mako), even nexus 4 has android 6.0! Previously, I was running CM 12.1 and I dirty flashed CM 13 on top of it. Although it doesn't have all the features that CM 12 had, with time, the awesome guys in XDA and cyanogen will port all the features to CM 13.

After dirty flashing CM 13 on top of CM 12.1, I faced some problems. First of all, things were kinda slow. So I went to Developer options in Settings and set all the Animation scaling to .5x. This considerable made things faster. Secondly and more importantly, my sim card was not getting detected and I was getting a ton loads of popups saying "Unfortunately the process com.android.phone has stopped".

I looked at the logcat to see what is going wrong and I found that this was appearing a lot of times.

Clearly, the problem was with com.android.providers.telephony. Upon looking closely, the problem was related to CursorWindow and Cursor. Hence, the problem was not with CM 13 but with the old database left behind by CM 12.1.

Solution

Just delete the folders /data/data/com.android.providers.telephony and /data/data/com.android.phone using some tool like Root Explorer or you can do this in adb shell.

rm -rf /data/data/com.android.providers.telephony

rm -rf /data/data/com.android.phone

Then, restart the phone.
