TensorFlow

tf.reshape(): Reshape tensors in TensorFlow

In this article, we have explored the idea of Reshaping tensors in TensorFlow with tf.reshape() and which models like GoogleNet use it.

Linux

journalctl in Linux

In Linux, systemd provides a centrally managed journal where all kernel and userland processes' logs are stored. We use journalctl to interact with journals.

Linux

SSH passwordless login in Linux

Passwordless login is useful in cases whereby we want to automate server administration tasks. We discuss how to configure ssh passwordless login in Linux.

Linux

Accessing a remote server using SSH

Secure Shell(ssh) is a cryptographic protocol for networking which encrypts communication between two remote hosts. In this article we learn how to safely access a remote server using ssh.

Linux

Managing packages with yum/dnf in RHEL

Package management involves managing software on a system. This includes installing, upgrading, downgrading, updating, removing, etc. We discuss package management in Red Hat Enterprise Linux Distros using yum and dnf.

Python

Factory Pattern in Python

In this article, we have explained the idea of Factory Pattern in Python with a complete Python implementation example.

Linux

Managing Debian packages with dpkg

In Linux software is considered a package and is distributed using remote repositories. As end-users, to access it we use package managers. We discuss the dpkg package manager for Debian-based Linux distros.

Linux

Managing Debian packages with apt

apt(Advanced Package Tool) is a package management tool. It is used to install, configure, search for, update and remove software in a Debian based Linux system.

Linux

Bash until loop

Loops are an important aspect in any programming language. In this article we look at the until loop that is used for looping in shell scripts.

Machine Learning (ML)

Similarity Search on Big Vector Data

In this article, we have explored Similarity Search on Big Vector Data along with Nearest Neighbor Search (NNS) or Approximate Nearest Neighbor Search (ANNS).

Operating System

Secure boot

Secure boot is a security standard implemented in the advanced UEFI to prevent malware from attacking the computer during boot up when the computer is most vulnerable.

Interview Problems on Array

MEX (minimum excluded) of a sequence (with updates)

In this article, we have explored approaches to find the MEX (minimum excluded) of a sequence (with updates) efficiently with pre-computation.

Computer Architecture

UEFI and Legacy boot

Both UEFI and BIOS are firmware that specify an interface between the computer operating system and the underlying firmware. Legacy boot involves booting the computer using legacy firmware such as BIOS and UEFI boot involves booting a computer using the more advanced UEFI.
