Every year, I publish a list of best technical talks of the previous year. Usually, these posts are published in the first couple of months of the year. 2020 and 2021, to say the least, haven’t been “normal” years, which explains why I’ve been dilatory in publishing this post.

A while ago, I wrote about how file descriptors can be transferred over Unix Domain Sockets between processes, when a parent child relationship doesn’t exist between the two processes. One of the use cases for file descriptor transfer between processes is during deployment of network proxies that handle ingress traffic…


A couple of weeks ago, I saw a demo of Waypoint, the new tool Hashicorp announced today, that aims to provide an easy, intuitive and customizable “build, deploy and release” workflow.

Bash Redirection: The Basics

A bash script is commonly a set of commands. There are three standard file descriptors of any command:

  • 0 → stdin
  • 1 → stdout
  • 2 → stderr

There are two commonly used redirection operators:

  • > output (This is the default operator for fd 1)
  • < input (This is the default


Update 12/31/2020: If you’re on a newer kernel (Linux 5.6+), much of this complexity has been obviated with the introduction of a new system call pidfd_getfd. Please see the post Seamless File Descriptor Transfer Between Processes with pidfd and pidfd_getfd published on 12/31/2020 for more details.

Yesterday, I read a…


All too often, I see comments or opinion pieces that read like platitudes about how every team should be hiring junior engineers. Let me start by saying that I’m all for hiring more junior engineers. …


All too often I see a lot of time and energy expended by people on social media on topics they obviously care a lot about. …


I recently read an excellent article in the Amazon Builder’s Library by Clare Liguori which goes into great detail about AWS’s CI/CD architecture. It’s a truly brilliant post and I recommend everyone interested in CI/CD infrastructures read the article. The article covers the gamut from unit testing to integration testing…


For the past few years, I’ve been publishing a list of my favorite tech talks from the previous year. As always, the usual caveats apply here, viz., this list isn’t comprehensive and excludes talks from many fields (blockchain, AI/ML, web and mobile development) that I do not have much experience…


As 2019 draws to a close, I wanted to jot down some thoughts on some of the most important technological adoptions and innovations in tech this past decade. …
