Welcome to www.VSubhash.in — the online abode of a writer, programmer and illustrator named 𝓥. 𝓢𝓾𝓫𝓱𝓪𝓼𝓱. That's me!
My articles on BASH (shell) programming and Firefox have been published in the September, October and November editions of Open Source For You magazine.
- I have made the ebook Linux Command-Line Tips & Tricks free on all ebook stores. If it is not available free from an Amazon Kindle marketplace,…
- In January 2023, an article titled How to create PDFs and DOCX files for free has been published in Open Source For You magazine.
- In February 2023, my FFmpeg book was published by Apress.
How to programmatically create HTML, ODT, DOCX and PDF for free
MarkDown is an easy human-readable text format that can serve as the common base for exporting to multiple document formats such as HTML, ODF, DOC/DOCX, PDF and ebook (EPUB, MOBI…). In this article, I show how to use CommonMark (MarkDown) and CSS to create validation-safe HTML and then use LibreOffice CLI to create ODT, DOCX and PDF documents from those HTML documents.
How to tame Mozilla Firefox
Firefox developers take no pride in their work. After Google Chrome showed up, Mozilla gave Google the mantle for browser development. For years, it has been imitating Chrome rather than doing its own thing. It routinely introduces breaking changes. It removes useful features such as RSS support. It alienated hundreds of thousands of users by abandonings XUL add-ons architecture in favour of WebExtensions created by Google for its add-ons. Firefox has also imported Chrome's attitude of treating users as morons. You cannot change settings. With every update, more and more settings become useless. It only allows settings changes only in corporate environments. This article shows how you can take advantage of this decision and trick Firefox into respecting your settings decisions.
‘Unlikely Stories’ book
Unlikely Stories is an anthology of horror and comedy stories based on several real-life incidents that the author had encountered. After writing over two dozen exclusively non-fiction books, the author was forced by several governments to name this book as ‘Unlikely Stories’ and release it only as a fiction title (!) with a rather quaint description. Their verbatim copy follows:
Boy meets girl. Both fall in love. Boy proposes marriage. Girl postpones decision for one month. Girl gonna leave next day. Until then, boy tries to impress girl by telling stories — funny stories… scary stories… and all kinds in between. No worries. Everything ends well.
The stories were tough to come by. Having given up on fiction years ago, the young man had to marshal some old personal anecdotes, wild tales told by strangers, and even some vividly detailed nightmares for his first novel. Like a male Scheherazade, he somehow wove those yarns together. They also just about helped him bag his babe.
As a result, the stories are mostly supernatural/paranormal fantasies with ample doses of action, sci-fi, romance, horror and humour. The entire book is in first person and everything happens very fast. There is never a dull moment.

How to Make Your Website Serve Pages Faster?
Browsing through CNN's HTML source code, I found a message asking for ideas on how to improve the site's speed. The CNN Labs team has already implemented several speed improvement techniques such as CDN, DNS prefetching, aysnc loads, and code minifying, and were interested in anything developers curious enough to look into their code could provide. Here are a few site-optimization techniques I came up with.
‘The Tall Tales Of Elephant & Ant’ book
From time unknown, Elephant and Ant stories have been popular with kids in Kerala. (There they are known as Aanayum Urumbum stories in the Malayalam language.)
The size difference between Ant and Elephant would make any friendship between them extremely unlikely but that is just the beginning. Sit back for a roller-coaster ride between myth and reality. All Elephant and Ant stories are tall tales. The more unbelievable the story is, the more funny it sounds.
‘How To Install Solar’ book
‘How To Install Solar’ is a heavily illustrated 2021 how-to guidebook for anyone interested in installing solar power systems. It starts with a simple introduction to home electrical systems, proceeds on to describe various aspects of solar power and options available for home owners, and then provides step-by-step instructions for installing a low-cost DC-only solar charge controller system for ₹6000 and a solar inverter system providing AC power backup for ₹30,000. Also included is an extensive FAQs section based on questions and reviews published by solar power users online.
The paperback is a full-colour book and is extensively illustrated with drawings and tables.
‘Linux Command-Line Tips & Tricks’ book
This is a hack collection for Linux command‑line warriors. Because of the shell's ancient history, BASH scripting has some odd programming constructs that are difficult to memorize. This book is a ready-reference for such archaic but crucial details. It is also at an advanced level. It assumes that you already know how to use the terminal and are adept at shell programming. It does not teach you the basics or try to be a comprehensive reference. It trusts your intuition and focuses on things that you are most likely to forget or be confused about. It devotes special attention to coding mistakes or unusual circumstances in which your script or command will fail. This second edition has plenty of screenshots and syntax-highlighted code snippets (only in paperback), all in FULL-COLOUR.

‘World Of Word Ladders’ books by Ólafia L. Óla

Word ladders are a wonderful pastime. They are neither tough nor easy. Whoever invented it seem to have found the right balance between exercising the brain and having fun.
These books have 100 word ladders each.
‘Animalia Humorosum’ book by Ólafia L. Óla
This is an illustrated children's storybook based on Aesop's Fables. The stories have been made more believable by changing the ending with a humorous twist.
The title is not Latin for 'animal humour' but sounds like it. This is a full-colour full-bleed large-print paperback.

‘Learn To Ride A Motorcycle In Five Minutes’ book
Of course, you can learn to ride a motorbike in five minutes! For most of my life, I did not know how to ride a motorbike. But, when I had to do, it took me only five minutes. On my first ride on my first bike, I travelled nearly 100 kilometres, across two cities and one national highway.
If you already know how to ride a motorized two-wheeler such as a scooter, then you know how to ride a motorcycle. Believe me. What you do not have is the mechanical knowledge of how a motorcycle has to be operated. This book will teach you that in an hour or less. Acquiring the skill takes less than five minutes and honing it will require a few weeks of practice.

Each time I installed Windows 8 though, I had to perform the same tweaks all over again. Hence, I have created this article where I can find it all in one place.

Support The Arts… Our Arts… Traditional Indian Arts
When I was in school, cultural programmes meant Bharatanatyam performances or Carnatic music recitals or folk dances. Today, teachers are so talentless that the only time they come close to arts is when they watch TV. It is no wonder that kids are dancing to film music at school functions. Parents do not demand better things from the schools because the rash of reality TV programmes on TV has numbed their brains so much that they are bereft of any intelligence and don't know what is best for their kids. Films and television are truly the bane of human civilization.

Kolaveri Di Hoax Demystified
Is Kolaveri Di better than Roja or Mungaru Male or even Shakalakka Baby? So, why is this unlikely candidate considered a hit with the masses?
Addressing the British Prime Minister, Ambedkar said, "Prime minister, permit me to make one thing clear. The depressed classes are not anxious, they are not clamorous, they have not started any movement for claiming that there shall be an immediate transfer of power from the British to the Indian people… Their position, to put it plainly, is that we are not anxious for transfer of power from the British to the Indian people."
Undead Myths In The Wake Of iDead Steve Jobs
In the age of push-button publishing and social networking, people seem to have become de-humanised, not knowing what their true emotions are. This became very clear recently in the wake of Apple co-founder Steve Jobs' demise. Condolence messages ranged from "hagiographic" to "outright lame." Nobody seemed to have put an effort. There was no honesty nor any genuine feeling.

Boycott Internet Explorer
This website started boycotting IE and urging Web users to switch to a better browser before it became cool to do so. Here is the pitch archived from 2009:
"I am tired of Internet Explorer's (IE's) bad behavior. I will not have any more of its nonsense. My website will boycott IE. If your computer operating system (OS) is Windows, then please use a standards-compliant browser such as Opera, Firefox, Safari, Chrome, or K-Meleon to browse this site."

Legal Terms and Conditions
The Internet is about freedom and sharing. Greedy corporates have taken the enforcement of intellectual property rights to a ridiculous extent. They pay politicians (legally and illegally) and create laws that leave the citizen little or no rights. It is easy to show them the absurdity of their audacious attempts at infringing our rights. If you are a webmaster, feel free to use these terms and conditions on your website. No attribution is necessary.

Do you believe God exists?
I was asked to write an essay on this topic as part of a written test in a job interview in 2005. This article is what I wrote. If you are curious, rest assured that I did not get the job. A few days later, I called them and asked for my answer sheet. They obliged me with a photocopy.

Context Menu Extensions For IE
These IE extensions, created in 2004, are testimony to the fact that my objections to IE are based on sound facts, not malafide intentions. Yep, I was a fan of Internet Explorer (once). I used to hate Firefox because it was very slow while IE was very quick. It was only after I became a webmaster on a professional basis that I realized what a poor browser IE was. (Even before that, I had moved to Opera.)
Although today I object to the use of IE, I understand that some people will be forced to use IE, say, as part of their work. These IE extensions are for those people.

‘How To Invest In Stocks’ book
The first edition of this book was written for the Indian stockmarket (in 2003) but remained popular around the world. This was because it was a plain-English guide to investing in the stockmarket. While this completely revised second edition retains this original premise, it also has a global focus, updated information and new chapters.
This book assumes that you do not know anything about how stocks, company law, finance or commerce, and takes you from there. It also has some useful 'extra' information that you will not find in any investment book and no business school will teach you. Mere book knowledge about stockmarkets will not help you understand the markets. Markets are influenced by news and information (there is quite a difference).
Dictionary of Indian English
This dictionary is available online and offline. The online form is in the form of a search. You can add it to your browser as a search engine.

Currently, it has around 400 words. In future editions, it will become a full-fledged dictionary.
