I have a tendency to fall into repetitive patterns of thought. They possess me and make me hopeless, agitated and resentful. But these thought loops are not permanent. They only last for as long as I am giving them my attention. During the depressive phases of my life I loved to sleep long hours and multiple times a...

A shitty analogy of the current CAA debate is the mankad in cricket. It’s not against the rules, but against the spirit of the game. Mankading, named after Vinoo Mankad for doing it a couple of times, is the dismissal of an unsuspecting out-of-crease batsman by the bowler during his run up. It is considered rude,...

This post has been adapted from a university project to understand and simulate the findings of [1] Preamble The evolution of a dynamical system is mathematically modeled as differential equations. Properties of the system like position and velocity at any given moment are the State of the system. Differential...

I am a heavy user of VLC media player, and I was a bit disappointed to find out that VLC is unable to utilize my NVIDIA card to its fullest for hardware accelerated video decoding. VLC supports hwaccel on NVIDIA cards through VDPAU, which is an open source API (even AMD and Intel have some support for it). Sadly,...

The Discrete Fourier Transform, takes in a sequence of N complex numbers \(x_0, x_1, \dots, x_{N-1}\) and converts them to another sequence, let’s say \(X_0, X_1, \dots, X_{N-1}\). Inverse-DFT or IDFT, as the name implies, reverses the DFT. This whole process of conversion and de-conversion is achieved using the...

The work on the MLP bitstream verifier had to be paused for some time, as things with more priority popped up. Bug #1 The encoder was unable to produce a lossless bitstream at transients, which was not a good thing. To fix it I had to finally understand how the FIR filters were used in the encoder as predictors. The...
