This feels very hand-wavey to me. I can patch and ship my docker images the same way I might patch a server. apt-get update && apt-get upgrade rinse, repeat. Secondly, all this cargo-culting around small containers is fine if you are cramming resources. I am not. The reality is that my projects and many others are really, really over-provisioned. Looking at my graphs right now, I am on the front page of HN and my ser…

"apt-get update && apt-get upgrade" You can do this exactly the same in alpine, with "apk update" and "apk add". "Secondly, all this cargo-culting around small containers is fine if you are cramming resources. I am not." The default docker python image is 885MB. python:buster-slim is 114MB which is much more reasonable. Even if you're not "cramming resources", pushing 885MB vs 115MB vs 20MB across the wire does add u…

Not just over time, it adds time.

Push new versions of one of those to 50 machines, versus the other.

Great writeup! I think it's useful to talk more about complete stacks instead of focusing on individual parts without mentioning the "glue" between them so I really like these kinds of posts. Just two questions: 1. If you're not going for scalability why Postgres and not SQLite? 2. What does your monitoring look like? I've read something about Grafana and Hetzner dashboards in the comments but what exactly do you use…

I love SQLite, but it really doesn't have a great answer to HA/failover. If you enable WAL mode, even NFS is off the table.

Right, but in this case that's not a thing anyways since there's only one server.

Honestly, frameworks like Rails or Django are an anti-pattern for Golang. The standard library makes it very easy to build web services and there’s a couple or popular packages for making routes and dealing with HTTP requests/responses simple. There’s projects like Micro that try to do a little more batteries included but I wouldn’t consider them to be pervasive in the way Django or Rails are. Beyond that, it’s just…

>Honestly, frameworks like Rails or Django are an anti-pattern for Golang. Which is, IMHO, the biggest thing holding Go back. The standard library does a lot but a lot is also missing. Authentication, db migration, admin panels, ORM, Asset pipeline and probably more. It's a lot of custom work to do or pulling in various libraries.

I have mixed feelings on this. I go back and forth on whether I agree or disagree.

For example, once an application becomes sufficiently complex, I've found ORM's to be more of a hindrance. The abstraction gets leaky and I end up having to tune custom queries to get around some pathological edge case.

That said - most of my experience is with Rails and a lot of the implicit nature of it is problematic. On the other hand, I've not had this experience with Laravel.

Which one is right? I dunno. Lately though, writing sizable web applications in Golang is working out well so I guess I'll keep doing that.

The main reason for me is that Postgres can be backed up while online, and I can scale up to multiple servers if I suddenly need to. Not so much with SQLite where if a small project suddenly hit the front page of whatever I would suddenly need to get really creative.

Can golang auto generate forms based on database models? An alternative explanation for why there is no Django for Go is that Go is not expressive enough to support such levels of abstraction.

I would have chosen user authentication as an example. Better have a team looking over this stuff than to write this up on you own except you know exactly what you are doing. Might end somewhere with you users passwords public readable in an elastic bean stack...

That is a double edged sword. Sure, that dynamically typed language of python or ruby might be quick to develop on but they often contain a lot of surprising bugs. Compilers catch a lot of bugs before your software is in production.

I don’t know. I keep seeing this argument. I’ve been developing on the Django stack for the past 10+ years. I have fixed many bugs if mine and of others. It has been extremely rare, if at all, that they were bugs caused by an incorrect type. The closest I can think of is a typo in a method or class name, but is it really a bug if you catch it instantly? These are just not the types of bugs that end up creeping into the code.

In the meantime Django provides productivity like you can’t get many other places. It’s just a pleasure to work with and aside from a couple of setting-related places it’s code is a pleasure to read.
