Bridging data types between the database and a programming language is such a
foundational feature of most database-backed applications that many developers
overlook it, until it doesn’t work. For many of my Rust-based applications I
have been enjoying sqlx which strikes
the right balance between “too close to the database”, working with raw cursors
and buckets of bytes, and “too close to the programming language”, magic object
relational mappings. It reminds me a lot of what I wanted Ruby Object
Mapper to be back when it was called “data mapper.” sqlx
can do many things, but it’s not a silver bullet and it errs on the side of
“less magic” in many cases, which leaves the developer to deal with some
trade-offs. Recently I found myself with just such a trade-off: mapping a Uuid
such that I could do IN
queries.
Howdy!

Thoughts on WebTorrent
WebTorrent is one of the most novel uses of some modern browser technologies that I have recently learned about. Using WebRTC is able to implement a truly peer-to-peer data transport on top of support offered by existing browsers. I came across WebTorrent when I was doing some research on what potential future options might exist for more scalable distribution of free and open source libraries and applications. In this post, I want to share some thoughts and observations I jotted down while considering WebTorrent.
Technically I'm microblogging now.
I am a big fan of the open web and although I have enjoyed Twitter the platform has regressed in dramatic form and function since I first adopted it. I remember Twitter actively avoided building a walled garden with fantastic APIs and RSS feeds open to the public. Much of the popularity of the platform hinged upon the incredible third party applications and integrations developers like me built in the first five-ish years of its existence. Over time the site has strayed from open APIs and standards, and while I still enjoy Twitter, I want some more flexibility which is why you can now subscribe to my microblog with any RSS-capable client.
Synchronizing notes with Nextcloud and Vimwiki
The quantity of things I need to keep track of or be responsible for has
exploded in the past few years, so much so that I have had to really focus on
organizing my “personal knowledgebase.” When I originally tried to spend some
time improving my information management system, I found numerous different
services offering to improve my productivity and to help me keep track of
everything. Invariably many of these tools were web apps. In order to quickly and
productively work with information, a <textarea/>
in a web page is the choice
of just about last resort. I recently revisited
Vimwiki and have been quite satisfied both by
my productivity boost and the benefits that come with having raw
text to work with. The best benefit: easy synchronization of notes with Nextcloud.
Reverse proxying a Tide application with Nginx
Every now and again I’ll encounter a silly problem, fix it, forget about it, and then later run into the exact same problem again. Today’s example is a confusing error I encountered when reverse-proxying a Tide application with Nginx. In the Tide application, I was greeted with an ever-so-descriptive error:
Multiple Let's Encrypt domains in a single Nginx server block
Nginx is a fantastic web server and reverse proxy to use
with Let’s Encrypt, but when dealing with multiple
domains it can be a bit tedious to configure. I have been moving services into
more FreeBSD jails as I alluded to in my previous
post, among them the
general Nginx proxy jail which I have serving my HTTP-based services. Using
Let’s Encrypt for TLS, I found myself declaring multiple server
blocks inside
my virtual host configurations to handle the apex domain (e.g.
dotdotvote.com
), the www
subdomain, and vanity domains (e.g.
dotdot.vote
). With the help Membear
and MTecknology
in the #nginx
channel on Freenode, I was able to refactor multiple
largely redundant server
blocks into one.
Using FreeBSD's pkg(1) with an 'offline' jail
In the modern era of highly connected software, I have been trying to “offline” as many of my personal services as I can. The ideal scenario being a service running in an environment where it cannot reach other nodes on the network, or in some cases even route back to the public internet. To accomplish this I have been working with FreeBSD jails a quite a bit, creating a service per-jail in hopes of achieving high levels of isolation between them. This approach has a pretty notable problem at first glance: if you need to install software from remote sources in the jail, how do you keep it “offline”?
Loving the PinePower
My current available working space is at an all time low which has made the dimensions of everything around me much more important. While I can never become one of those extreme minimalists that works with only their laptop on a park bench, next to their camper van (or whatever), I have been pushing myself to become more space-efficient with my electronics. This includes how they all are powered, so when I learned about the PinePower device, I ordered it immediately.
Intentionally leaking AWS keys
“Never check secrets into source control” is one of those rules that are 100% correct, until it’s not. There are no universal laws in software, and recently I had a reason to break this one. I checked AWS keys into a Git repository. I then pushed those commits to a public repository on GitHub. I did this intentionally, and lived to tell the tale. You almost certainly should never do this, so I thought I would share what happens when you do.
Corporate dependence in free and open source projects
The relationship between most open source developers and corporations engaging in open source work is rife with paradoxes. Developers want to be paid for their work, but when a company hires too many developers for a project, others clutch their pearls and grow concerned that the company is “taking over the project.” Large projects have significant expenses, but when companies join foundations established to help secure those funds, they may also be admonished for “not really contributing to the project.” If a company creates and opens up a new technology, users and developers inevitably come to assume that the company should be perpetually responsible for the on-going development, improvement, and maintenance of the project, to do otherwise would be “betraying the open source userbase.”
