The second wave of coronavirus is here in India I read this article from indian express in the morning. The daily cases yesterday were over 50000 for the first time since November. There are reported cases of multiple new variants (in a situation were DNA sequencing is extremely rare). The situation is frightening, especially some of the new variants being able to evade the immune system much more efficiently. I have been wearing a mask in public spaces at all times, but nobody else seems to be interested in doing so....

Today I am going to run a 7 segment display off of raspberry pi 4. The code I ran #!/usr/bin/env python import RPi.GPIO as GPIO import time pins = [11,12,13,15,16,18,22,7] dats = [0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71,0x80] def setup(): GPIO.setmode(GPIO.BOARD) for pin in pins: GPIO.setup(pin, GPIO.OUT) # Set pin mode as output GPIO.output(pin, GPIO.LOW) def writeOneByte(val): GPIO.output(11, val & (0x01 << 0)) GPIO.output(12, val & (0x01 << 1)) GPIO.output(13, val & (0x01 << 2)) GPIO....

The most surprizing aspect of neural networks is their simplicity. I don’t mean that the whole of a neural network is simple. It is not. But at any given instant you are either adding numbers or applying a function on one number (a single variable function). Why these two kinds of operations will give you any old function of multiple variables is a mystry to me! Let me take a small step towards understanding this by reading this really old paper by Kolmogrov....

Why Go? Computer evolution more cores programming languages based on one core programming Programming workflow evolution not written by single developer written at different times programmers write library or package to be used elsewhere open source code needs to be shared Go rethinks object-oriented development allows for code reuse let’s you use all cores no need to recompile evrytime. Learn concurrency model fast compiler syntax type system concurrency channels testing, etc How Modern programming challenges Go away Currently choice between rapid development : Ruby, python fast execution : C, C++....
