Hello! I’m Justin! I’m just a run-of-the-mill data scientist/software engineer who likes learning things in his free time. Specifically, my interests generally fall into Open source/emacs, applied mathematics/statistics, programming language design, Catholic history, poetry, and general pop-culture/anime/manga/-inserty nerdy thing here-. I would also note that I’m not a venture capitalist, despite said domain name. I dunno, thought it sounded neat. I’m honestly baffled that Justin Kan didn’t own the domain. But if you wander into this and you’re a VC who’s hiring, I wouldn’t be opposed, just ‘sayin

I draw inspiration from Gwern, in design, not content (mostly, I’m not rewriting this into Haskell), but maybe I’ll grow the writing chops eventually, but I also do not necessarily have the want to engage in survive-the-end-times-canticle-of-st-leibowitz type of writing. I plan to focus more on general notes and learnings. I would like to venture into longform writing more, but that remains a future goal. If you can’t tell by now I’m pretty freeform-thought-of-conciousness in my thoughts. Hoping the more I write the better I get about it. I was good at writing papers in college, but that was when I -had- to. Those skills have kind of lapsed a decade later.

Right now I’m basically vibing in the rural United States, having been on sabbatical for a year. I mean, I call it a sabbatical but it’s more of a weird covid break combined with wanting to randomly tinker around with other things. Dealing with corporate dashboards gets a bit soul draining after awhile. Would like to eventually move to a more walkable urban environment as the kick-in-the-pants to be (more) social. Difficult to want to do things when you have to drive 30 minutes.

This site is created with a fork of PaperModX, which I’m calling PaperModulo. Everything is written as org-mode documents that I parse with ox-hugo. Hoping that having -everything- as org mode documents makes it easier to write in general, since I use org-mode for my agenda/todo lists, reading (org-noter + pdf-tools) and Okay, sometimes I still use Jupyter and VSCode. Sue me.

In my day-to-day when working I’m generally using Python, at home I’ve started to use Julia for more projects but I don’t see as much non-research employment opportunities in it yet. I admire the beauty of correctness in Rust/Haskell/Idris, etc. but that’s more of a side-hobby. If you can’t tell I tend to get nerd-sniped pretty easily, it’s been something I’ve been working on. It’s honestly interesting how useful a plain linear regression is in the age of deep learning. I think even new-entrants to the field could find enough low-hanging-fruit to keep themselves busy with classical statistical methods and rudimentary machine learning.

That being said, I’m mostly self-educated when it comes to mathematics and coding. My undergraduate degree was in business and real estate. I actually was doing a double major with religion but didn’t finish it. (Not so fun) fact, I originally wanted to be a priest. I did a graduate-degree in decision sciences, but there’s only so much you can cover in two years. I primarily focused on optimization and information systems at that time with my “capstone” focus on education system turnouts in Bolivia.

I have my own little battlestation that I do my work on, I’ve never been a big laptop person. This is probably (one of the many reasons) I’d do poorly as a consultant. I like using Linux because See my dotfiles. Outside of not being able to (easily) do VR, I don’t particularly miss Windows, and I’ve never been a fan of MacOS. I’m just waiting for the day they put Asahi Linux on the ARM chips.


I think the linktree style svg’s of all your associated links are a bit gauche. Give me a good ‘ole table-of-contents-style of list.


Sites that are part of this site, generally things that are separated off and built using different technologies. Generally all hosted on github.

  • https://quotes.justin.vc - There’s a neat extension called Quotebacks for chrome/firefox that lets you record snippets of text. It’s useful for display, but it also saves things as JSON, which I parse and just toss into this site. Not the prettiest thing, but it gives a breakdown of things I’m randomly reading or have seen other people say. I think they’ve since stopped updating it, but it still works, so, eh. Might write a parser to put them into a table and make as a section of this site.

  • https://zk.justin.vc - The original top-level of this site, a zettelkasten written in TiddlyWiki. It has its own about page, but a lot of it I need to rewrite. I’m working on some pandoc filters to move my “general notes” programatically to it. Effectively a brain dump and more meant for my own uses.

Social Media/Following

Outside of things listed on blogroll, I don’t tend to like social media and talk to most friends via signal / matrix / Yeah, yeah, I know. The bots are neat and it’s mostly spamming stickers to my friends. Probably falling on deaf ears, but most social media is a waste of time outside of finding friends. Once you’ve found said friends, what’s the point, really? I get existential ennui, but, like, go read a book or get involved in your community (unless you’re getting paid to post, I guess, then continue on).

  • LinkedIn - I try to keep up with (job) roles and such in this. I keep descriptions blank because it’s basically just used to datamine. I figure if someone’s -really- interested in someone as a candidate they’d be Hi recruiters / hiring managers! If you read this feel free to mention it. You'd be surprised how often people don’t do a cursory reading of something other than their resume. Usually garners more points from my side.
  • Github - Keep most coding stuff here. I’m not a -huge- fan of Microsoft, but I like the UI better than Gitlab, and now that they have actions, there’s not really a killer feature differentiating the two.


I like to read. Generally non-fiction (technical / history / religion) and then science fiction / fantasy.

  • Goodreads - I try to keep books I read up to date / suggestions, etc. All reviews/notes are generally hosted locally, but I’d like to venture into book review type of writing. I do find the Goodreads API useful for marking things from Calibre so it’s generally used to just to keep track of things in a way people can see.


I like to watch things. I usually try to watch anything thats critically acclaimed in some way. I should probably cut back on it though. I’ve noticed that even highly rated stuff nowadays doesn’t really compare to written works.

  • Trakt - television/movies watched, programatically updated/scrobbled. May duplicate things if I fall asleep watching them, and I tend to watch things at x2-4 speed unless high-art/prestige.
  • Anilist - similar to Trakt, but anime/manga, programatically updated for anime. Might make a myanimelist also to sync between later. Truthfully only chose one over the other because there was easier syncing for the former.


Music doesn’t really tend to do much for me unless paired with visuals I can see. Trying to get more into it, but I generally only use music as a distraction in noisy environments. On the rare occasions I’m listening to things I like ambient post-rock / doom/sludge/stoner metal with occasional euro-dance / jazz. I feel like I would also have to turn in my southerner card if I didn’t admit to liking bluegrass and gospel.

  • last.fm - music scrobbled from Spotify
  • rateyourmusic - rating albums, manually updated (rarely - a note to do this more)
