Fixable Problems

October 2020 ยท 7 minute read

It’s Wednesday night. So far it’s been a good week–I’ve found my way back into the working cadence that I like. This is what I hoped I’d eventually be able to do–take a real shot at making my skills as valuable to me, the human, as they would be to an employer.

It’s taken longer than I hoped to get here. I left my job at the end of July– though I don’t think I was leaving that job, which was pretty new, so much as I was stepping off the commercial-software-development treadmill for a bit of a rest1. As I’ve mentioned, I had planned to explore ways to support myself through various kinds of traditional crafts. I started moving in that direction–working on designing standard-ish objects that I would be able to make and sell–but a feeling of unfinished business remained. It seemed hypocritical to take the money I was paid for working in the systems that are eating the world, then wander off to a quiet spot and work on my pottery and sewing like the accounts were balanced. Besides that, I like programming. It has the same kind of appeal as doing a crossword puzzle or playing Tetris, but when you’re finished, there’s something new in the world. It makes me sad to see how much of the effort spent programming–like the effort spent doing most commercial and leisure activities–redounds to the benefit of a tiny minority of extremely wealthy people. It makes me sad that out of that, somehow, programming is what gets a bad name– as if it’s the intellectual activity of writing code that gentrifies neighborhoods or moves factories overseas, and not billions of tiny acts of unthinking capitulation to the logic of markets. I didn’t want to leave on that note.

If I’ve been short on specifics for the past couple months, it’s because I didn’t have specifics to share. I knew my intended direction of travel but not my route, and certainly not when or where exactly I might arrive. Those things are a little clearer to me now–at least, I can describe some of the concrete details of what I’m working on day-to-day. What I’m about to talk about should be considered work-in-progress, and I reserve the right to about-face on any of it if my perspective changes.

I’ve been working on three specific projects. The first one is the cloud infrastructure that lives in github alongside the code for this website. A lot of that work has been on “overbuilding” some of the more basic components–things like log management2 and permission management3. My number one rule for system design is that the right way to do something must be made the easiest way, because the easiest way is what people are going to do, whether it’s the right way or not. Since my ultimate goal is that you, reader, will be able to deploy and maintain your own system like the one I am building for myself, I would not like to embarrass myself by giving you something that is going to break4.

The other two projects I’ve been working on are a pair of code libraries: exploranda-core and donut-days5. The purpose of those libraries is to make it easy to put any system together at the speed at which you can describe it, without being tied to any particular vendor or platform. I’ve been using AWS, but I’m making sure that nothing I’m building relies on AWS and isn’t also offered by competing vendors.

Because my goal is that anyone should be able to build whatever system happens to be right for them, I need to start with some example systems that I can build and simplify until they meet my standards. The first of these projects is a personal image management system. I want to combine the use-cases of storing and organizing a lifetime’s worth of images with the basic social-media use-case of sharing images publicly or with your friends. This is something that I need for myself and a good entrypoint into the set of services that many people require. One way that I look at these example services is in terms of capabilities. Image-management requires the capability to send and receive data, to work from mobile devices and computers, to publish on the internet, and to search, read, and edit metadata (when a picture was taken, what’s in it, etc). The difficulty of doing all these things well is part of what makes for-profit social media such an attractive proposition. Other capabilities that are not included in image management, but which I intend to address in the fullness of time, are sending and receiving payments and true federated identity6.

I don’t mean that I’m going to invent a new identity system, and I’m just profoundly uninterested in cryptocurrency. My confidence actually comes from how obvious and boring the solutions to these problems really are. There are plenty of payment processors who offer access to the regular credit card and banking systems at reasonable rates7. Likewise, there are extremely well-understood and trustworthy ways of verifying identity, suitable for social media use, that do not rely on Facebook’s or Google’s login system8. It was a big deal when facebook started doing facial recognition on images in 2010. Now there are simple ways to do it on a raspberry pi. Paypal is old enough to vote. Technology has not stopped moving in any of these areas just because people already got rich off them. But the benefits of technology do seem to have stopped making their way to ordinary people quite like they were doing at the middle and end of the last century. And that is a fixable problem, if enough people care about it.


  1. The opportunity to do this is so obviously key to my mental and physical health that I think it should be guaranteed to everyone, whenever they need. Whatever obstacles exist to that becoming a reality, shortage of resources does not seem to be one. ↩︎

  2. Well-behaved software keeps records of what it does. These records are written to text files called logs. How to manage these logs–how to balance “being able to understand the system” with “not being overwhelmed” and “not paying too much”–is an art form. ↩︎

  3. The principle of least privilege states that a system component should only be given permission to do the specific things it needs to do. For instance, an application that only needs to read from a database should not be given permission to write to that database, or to read from any different database. In practice, it’s common for an engineer to develop in a permissive environment (for instance, to give their program full access to a test database) and then try to restrict access down to the minimum when it’s time to deploy to production. I do not find this approach to work well–on the technical side, it can be hard to determine the required set of privileges without significant trial and error, and on the human side, people sometimes cut corners when they’re rushing things into production. These factors work against someone trying to do least-privilege after the fact. I described a central part of my least-privilege strategy in an earlier post ↩︎

  4. I’m all set for ways to embarrass myself without adding any more. ↩︎

  5. I’ll think of some kind of prize for the first person who successfully figures out the reason for that name. ↩︎

  6. It’s not immediately obvious, but login is one of the core features of every for-profit social media system. The ability to like or comment on a post relies on the fact that the system knows who you are–part of what’s important about getting likes is that you can see who they’re from, and you know (usually) that it wasn’t just a bot clicking on the like button a bunch of times. The fact that a celebrity’s social media accounts are reliably theirs, not those of an impostor, are why those accounts are valuable. No popular social media system uses a way of getting those assurances without relying on a central system (the “federated” part). There are well-known ways to do it, but they haven’t yet been widely applied to social media. The big money is in getting everyone under your roof, not giving everyone their own. ↩︎

  7. I’m defining “reasonable” here as “better than what you can get from rent-seeking market owners,” not in a universal sense. ↩︎

  8. I’ll give you a hint: you don’t have any trouble finding the right website for your bank. ↩︎
