This wiki

This is an Oddmuse wiki.

This will probably always be under some form of construction.

This weblog + wiki is running on Oddmuse. It is heavily inspired by Alex Schroeder's setup who developed Oddmuse. This wiki is served by an Apache webserver on a Linode instance.

Why Oddmuse? I like the concept of a wiki, and it seems like the sort of place one could share a mixture of interconnected notes, and progressively improve them or let them be. Odddmuse is relatively easy to setup, deploy and use. I like the general ease of creating and collecting pages with tags and searches. Beyond all this, the EmacsWiki runs on oddmuse ;)

It functions as my blog and wiki, and is a social and technical experiment of sorts to maintain a wiki and publish content that forms a hyperlinked garden - a Zettelkasten of my own, propelled by Emacs and Howm.

Hat tip to bandali on #emacs for directing me towards Oddmuse. Visit #oddmuse on Libera to talk to AlexSchroeder, AlexDaniel?, CapnDan and others who created + drive the development and use of Oddmuse.

I also have a static hugo site at https://shreyas.ragavan.co up at the moment. The idea is to port over content to this wiki.. atleast for now, and well, at some point maybe dig up and finish a draft about the history of my web presence.

Notes for posterity

The license above was initially adapted from Emacs Ninja site. The author of the website also pointed me towards Audio/Video - GNU Project - Free-Software Foundation where a similar CC BY-ND license was used. It made sense to me that I would prefer being asked before derivatives or remixes are made to content that I publish.
The GPL V3 was chosen (over the more permissive MIT or other licenses) because I like the general idea of being able to assert a copyright, but also support the freedom for others to use it.
The above (as with any personal opinion and preference expressed on this site) may change in the future as I learn more about licenses and my perspectives change.

Me

I am Shreyas Ragavan.

I started my career as a mechanical engineer and computational physicist with a passion for design engineering and more specifically for Computational Fluid Dynamics or CFD.

While I do love the subject and allied subjects like Aerodynamics and Combustion, somewhere along the way - I migrated to Data Science and Machine Learning which seemed to have a lot more opportunities.

I've worked across a number of domains, industries and roles over 11+ years and at my core, I enjoy solving (hacking through) problems and developing multi-disciplinary solutions at the intersections of technology, business and fun.

I love the idea of Free Software, though in practice, beyond a point - I use the tools that I need to - since I lack the talent and time to write all my own software. That being said, most of my meaningful computing takes place in Emacs.

My projects are listed on the Projects page.

Social stuff and contact

I typically use the nick shrysr on IRC channels and Github. I'm not very active on any particular platform or account, and prefer communication via email.

I would welcome connecting with you, the person reading this wiki and especially if you have any comments on the content!

I also run one other experimental wikis and sites like:
- a datascience job description wiki

Things I use

Hardware

Macbook Pro 2018 15" 32GB RAM
iPad Pro 10"
iPhone 14 pro max
Keyboardio Model 100
Keyboardio Atreus
Logitec MX-Ergo (Thumb trackball)

Software

I love Emacs, and tools like OrgMode kind of changed my life and approach to things.

Emacs (Mail, Writing, blogging, code, literate programming, managing my VPS, etc :D)
VS Code (not my favorite, but unfortunately, I use it at work)
PyCharm? (Python, DataGrip?)
RStudio (R)

Paid Services and applications

PyCharm? (Python, DataGrip?)
Pinboard: to collate my webcaptures and these are pages that show the RSS feed of specified hashtags. I would recommend checking out the inexpensive Pinboard service. It has everything needed to bookmark and collate information from the internet and excellent levels of privacy and sharing options.
Readwise: After reading about the power of spaced repetition and the desire to retain more of what I read, I signed up for Readwise and am currently using their RSS/Read it later service called Reader as well.
Newsblur: I was a very happy newsblur user for nearly 2 years, and still maintain a subscription.
Soma FM : Replaced my use of Spotify in 2023.
MarginNote?: for marking up PDF's and longer documents to build mind maps.
GoodNotes? : Handwritten notes and sketched using my Apple Pencil.
Procreate : I used to enjoy drawing and crafts in my younger years and hope to pick it up again with this app.
DevonThink?: Mac, iOS and PadOS? applications. Things like receipts, tax documents and other archival documents go into this. It also indexes my Org archive of notes, as well as any other notes that I capture on the go.
icloud: Additional storage, mostly to facilitate device backup. The only additional storage service that I happen to use at the moment.
