I've just published a minor update to my uv with Django blog post where I expanded the section on running Django in prod:
uv run --no-dev --frozen gunicorn your_app.wsgi
I also added a brand new section on how to run tests in your CI:
uv sync --frozen
uv run --frozen pytest

I'm amazed that fedidevs had its 100th user sign up yesterday. So far the tool helped made over 1500 new connections on Mastodon! 🤯

First time that I see template rendering being a bit of a bottle neck in a Django app.
This was on a Raspberry Pi 4 while all 4 cores were over 80%.

yeah that's the issue, I can’t fit 3 columns on mobile so it kinda needs to be a front-end solution. I think this isn’t even possible with css only so it is quite annoying 😞
I have considered removing masonary grid or making it optional and show a single row by default. I’ll see.

Prompt cont.
Classify as project (P) if the account is a project/company/bot and it refers to itself in plural (we) and doesn't have a name/surname. Output only the classification letter nothing else.

LLM's of course aren't prefect for this sort of thing so there are a lot of mislabeled accounts. If you see one let me know and I'll fix it manually!

To get this to work I tagged over 10k Mastodon accounts with ~70 lines of Python and $0.56 of API costs (using GPT-4o mini).

Prompt:
The input is Mastodon account text data including a bio, name, and link. You have to figure out if the account is a human or project/company/bot. Classify it as a human (H) if it has a name, surname, hobbies, refers to themselves in singular, uses I or has pronouns set.

yes, that makes all the sense. It's sometimes very difficult to see that you are spending more money by wasting your time instead of actually spending some money.
In this particular example I'm spending some change on a personal project that is not making any money, so there's no salary and no additional costs for me to justify the spend 😅

2024-08-06 13:37:14

Writing code that costs money to run is nerve-wracking, even when the amounts are tiny and limits are in place. 😅

raspibackup is good for general backups, but don't rely on it for db backups (unless you put the db in read-only mode while backing up).
To be safe, always use the built-in backup commands or online backup tools for database backups.

Has anyone ran into the hash mismatch issue when installing Django 5.1rc1? I got this error on my raspberry pi, but cannot reproduce on my intel macbook.
pip install django==5.1b1 installs without issues 🤔

oh wait, I think you made a typo when trying to log in: mato.bike instead of masto.bike.
The server shouldn't return a 500 in this case and I'll fix this later, but I think you should be able to log in!

Ok, second iteration: Move the order to the top and make it two dropdowns.
When the order period is last 7 days, show the change in followers for that period and don't show the total number to make the profile cards less busy.
Thoughts?

I'm trying to figure out how to show the daily/weekly/monthly change in follower count on https://fedidevs.com. Current solution is to allow ordering by daily/weekly/monthly and then show triangle + number, but I'm not sure if this is clear.
Any other ideas?

super strange. I think it's because not many command line tools use under scores for command/parameter names so it feels weird seeing them in the terminal.

2024-07-04 14:13:16

I don't know why, but I prefer `python manage.py findinstances` over `python manage.py find_instances` 🤷
I should probably revisit the names of the commands because most of them don't really make sense 😅

Any idea why PostgreSQL is this much slower compared to SQLite and MySQL?
This is on Ubuntu 24.04, connecting through Django and I've tried both psycopg and psycopg2, but the result is the same: ~200 requests per second with Postgres compared to ~2000 with SQLite or MySQL.

I think the point was to not randomly talk about yourself for 2 minutes, but instead focus on the topic of your presentation and explain yourself through it. E.g. Instead of saying: I’m a sw engineer, say: I was programming a solution for (subject of the talk).

2024-05-22 13:35:52

yes, put your name/contact on the title page and then next slide should be the content of your talk and you introduce yourself as you go through it. A dedicated about me slide should be avoided.

2024-05-22 13:22:54

Quick takeaway from the public speaking workshop: you don’t need an about me slide.

get the 5, I think they should be in stock everywhere (check the official site for resellers in your country)
Be careful when choosing the SD card, there are huge differences in read/write speed so make sure you get a fast one.

2024-05-14 10:00:18

One thing that I'm missing with HTMX and Django is proper error handling.
By default HTMX swallows any response that is not a 2xx, which might leave your users hanging on an endless loading state.
Does anyone have a good solution for this that can be reused between projects?

I have a raspberry pi running at home with 4 different sites. Honestly, it's not that much work and you don't even need a dedicated IP from your ISP if you are ok with a few minutes of down time every couple of months.
