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 this:
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

Open with script in Gnome/Ubuntu

I always liked the feature open with script which was there in old ubuntu. I have no clue why they removed it. However as always in Linux there is always a way to do anything! Today I will show you a simple way( complex than before though ) to do it. Using this I was able to install Picasa Photo Viewer, Logism, yEd, MS Office..etc on my Ubuntu \m/

Step 1: Find MimeType of the target file (the file you want to open). You can find it in file properties

Step2: Download this gist. And make it executable:

$ chmod +x open_with_script.sh

Step3: Then run the script and enter necessary details. For example I was trying to install yEd, an awesome Software Engineering Drawing tool. This is what I did:
NOTE that if the command is <command> <file name> enter as <command> %U

Step4: This step is optional. This is to set font to the script. If you don't wanna do it, skip it. Open application called "Main Menu" or alacarte which comes by default in ubuntu. Then search for the script you just added and then set the font.

Step5: Now just set the file to open with the script by default if necessary using file properties.

Now you can simply open the file using yEd by default. So you are done!!!
