Introduction

Mon, 02 Jan 2017 13:25:43 -0500

Welcome to cgbaker.net, the personal webpage for Chris(topher Grover) Baker. It’s part blog and part project warehouse, my own little non-peer-reviewed piece of the internet.

This replaces my previous academic webpage. This is partially out of necessity, as the former site is no longer accessible to me because it was hosted at the Computer Science and Mathematics Division at Oak Ridge National Laboraties, where I previously worked. But it also serves to curate a broader set of interests than did the former. In addition to my (very gradual) ongoing research in linear algebra and Riemannian optimization, my intention is to write about cloud computing, dev-ops, programming, homebrewing, and whatever DIY I get around to writing up. So feel free to check out the projects link in the menu, the blog post categories listing, or my bio.

Site Architecture Update

After experimenting with some other sites, I’ve shifted the hosting for my website from AWS S3 to Cloudflare Pages.

Flame Point Brewing

Mon, 17 Feb 2025 09:32:45 -0600

After recently pouring beer under the banner Flame Point Brewing, we decided to make it official and launch https://flamepoint.beer.

The Why and How of My Unitank

Tue, 27 Apr 2021 15:42:00 -0500

When retooling my home brewery last year, I decided to go all-out and buy a unitank. This post outlines why that’s overkill and why I’m glad I did it.

Adding Heating to the IceMaster Max 2

Sat, 09 Jan 2021 11:47:00 -0500

My glycol chiller includes two-stage temperature controllers. With just a little bit of work, I was able to expose this capability and add a heating circuit for my fermenter.

Hacking Nomad Job Dependencies

Sat, 05 Dec 2020 08:33:00 -0500

One of the oft-requested features for HashiCorp Nomad is job dependencies. I took some time this week to see what can be accomplished for simple workflows using Nomad-native features.

Marianna Green Chile Harvest 2019

Sat, 05 Oct 2019 17:43:00 -0500

I missed out on the green chile harvest in 2018, so you can imagine that the small amount of chile I put away in 2017 was gone. Someone in the #talk-food channel in the work Slack mentioned that the chiles had come in, so I struck hard and fast this year.

Tallahassee Green Chile Harvest 2017

Tue, 05 Sep 2017 23:04:00 -0400

Of all the things I miss from living in Albuquerque, the two most significant are the weather and New Mexico chiles.

PBW is my best friend

Sat, 29 Jul 2017 09:51:05 -0500

One of the benefits of engaging in such a broad subject as home brewing is the secondary use for all that equipment and random knowledge. Friend needs to borrow a 7 gallon glass jug? I have one of those. Brother-in-law needs to rapidly cool down 6 gallons of boiling liquid? I can help with that. Neighborhood lemonade stand wants to know the specific gravity of their signature beverage? No problem.

Return to brewing: English Dark Mild

Sat, 04 Feb 2017 18:48:52 -0500

We moved to Tallahassee in 2013. Between a new baby and a new startup, I ended up taking a break from homebrewing. For over three years, as it happened. Last year, I started again as assistant brewer for a friend, @ChrisAsa1, who is much more dedicated, to the extent that it eventually shamed/inspired me into cleaning up my equipment. Three weeks ago, I decided it was time to end my dry spell, as it were.

MathJax support for rendering equations

Mon, 16 Jan 2017 18:09:21 -0500

Update: Tranquilpeak has added built-in support for MathJax.

If I’m going to occasionally write posts about math (and that is the plan), I need the ability to render equations. It’s not a strict necessity; you can get pretty far by literally describing what it is that you’re trying to say. For example:

The Riemannian gradient over the compact Stiefel manifold of the Rayleigh quotient with respect to some square matrix and a given conformal subspace can be computed as the orthogonal complement with respect to a basis for that subspace of the product of said matrix and said basis.

Anova sous-vide circulator, and sous-vide chicken wings

Thu, 05 Jan 2017 14:31:52 -0500

I’m a bit of a gadget freak, and this tendancy applies in the kitchen as much as anywhere. I’d been meaning for some time to get a sous-vide circulator, and last May (2016) I finally broke down and purchased the Anova Precision Cooker.

New site architectural overview

Tue, 03 Jan 2017 15:57:32 -0500

As I promised in the intro, here’s a breakdown of the software and processes used to construct and delivery the site:

Hugo: flexible static site generation from markdown
Gitlab: version control for site source, continuous delivery system
Amazon Web Services (AWS): static content hosting, load balancing, content distribution, certificate management
