Weird Flask bug: MySQL time not showing in HTML

Title:
Weird Flask/MySQL bug: start_time won’t show in <input type="time">, but end_time does

Body:
I’m running into a strange issue in my Flask app with MySQL TIME columns.

Table snippet:

mysql> desc tests;
+-------------+-------+
| Field | Type |
+-------------+-------+
| starttime | time |

Bug in Python 3.13 wave module? getnchannels() error on cleanup.

Hey everyone,

I ran into a really strange error today while working with the built-in wave module in Python 3.13 and thought I'd share in case anyone else encounters this or has some insight.

I was trying to do something very basic: generate a simple sine wave and save it as a WAV file using the standard library. My code was the textbook example, using wave.open() inside a with statement to handle the file.

The weird part is that my script runs, but then throws this error right at the end, seemingly during the internal cleanup process after the with block closes the file:

wave.Error: # channels not specified

My code to set the channels (wav_file.setnchannels(1)) is definitely there and in the correct order before writing the frames, so it doesn't seem to be a problem with my script's logic. It feels like the library is failing internally when the file object is being destroyed.

Has anyone else seen this with Python 3.13? Is this a known bug in the new version?

Thanks!

Does creating a new CMS system based on django make sense?

Hi everyone, I have used wordpress for long time in my career, but security point of view always eats my brain. with lot of plugins comes lots of security holes.

Since django being best in industry for security. can make sense to bring it as alternative to wordpress.

Need your perspective.

I created a wrapper for google drive, google calendars, google tasks and gmail

GitHub: https://github.com/dsmolla/google-api-client-wrapper

PyPI: https://pypi.org/project/google-api-client-wrapper/

What my project does:

Hey, I made a simple, and easy to use API wrapper for some of Google's services. I'm working on a project where I need to use google's apis and I ended up building this wrapper around it and wanted to share it here in case anyone is in the same boat and don't want to spend time trying to figure out the official API.

Target Audience

This is for developers who are working on a project that uses Google's APIs and are looking for easy to understand wrappers

Comparison

Data Models like EmailMessage, Event, DriveFolder, Task vs. Raw API responses
Helper Methods
Built-in support for multiple accounts
Query builders vs. Manually writing raw queries
Clear documentation and Easy to navigate
Similar patterns in all services


I will add async support soon especially for batch operations

I generated a visual diagram for Flask

Hey all I recently created an open-source project which generates accurate diagrams for codebases.
As I have used flask multiple times in my past for simple endpoint projects I generated one for the community here:

https://preview.redd.it/ttm0nghbkoif1.png?width=1292&format=png&auto=webp&s=3527dfa2a6131082ea7fc39fbf2184593655ad33

It is quite interesting to see how it differentiates from other framework as the diagram gives a quick overview of what actually happens under the hood. The diagram is interactive and you can click and explore the components of it and also see the relevant source code files, check the full diagram is here: https://github.com/CodeBoarding/GeneratedOnBoardings/blob/main/flask/on\_boarding.md

I made this “plug and drop” Django library and need some advice

I’m learning Django and Python at work, and to push myself I built a “plug and drop” Django library with several small apps — accounts, profiles, logging, and even 2FA. I’m still struggling with the basics though, and I’d love advice on how to improve my learning process.

The company I work for is *really* small — about 5 people total, including me. We’re only two who code, one who designs the websites (mostly via WordPress), and one who handles SEO and marketing.
Before I joined this team, I hadn’t coded for about 5 years, and back then it was mostly HTML and CSS.

Here’s my issue:
I understand about 75% of the code written by GPT or the other coder in the company, but when it comes to simple things like `for` loops, `if/else` statements, and basic Python/Django syntax, I often can’t remember or figure out how to write them from scratch.

To help myself learn, I came up with the idea of making a small library of apps that could be useful and also serve as a learning project.
It consists of:

* **An account app** – simple login and registration form, built with a custom user model (not

How to properly register a user

Hey, I have an app where users can register either as Sponsors or as Watchers (normal users).
Currently, I have two apps:

Sponsor, with its own [`models.py`](http://models.py) containing specific fields
Watcher, with its own `models.py` containing different fields

Now, I'm wondering:
Should I create a separate app called User or Accounts to handle all user registrations centrally, and then redirect users to the Sponsor or Watcher apps to complete their profile registration?
Or should I have separate "Register as Sponsor" and "Register as Watcher" links that lead directly to the respective Sponsor or Watcher apps, where registration and profile completion are handled independently?

FT8Decoder - A Library for the Parsing and Enrichment of FT8 Radio Messages

Hey everyone! I just released my first Python package, [FT8Decoder](https://pypi.org/project/ft8decoder/).

Earlier this summer I got into amateur radio as a hobby and stumbled across [FT8 transmissions](https://www.youtube.com/watch?v=qInOSHfT8jA) while exploring WebSDR. I was intrigued by the spooky alien sounding tones and wanted to know what they meant. I installed WSJT-X, which decodes them in real time, but as a newcomer, “CQ ABDCE FN41” or “KWB8R KCQ4N R-08” didn’t really give me the clarity I was looking for.

So, I went looking for a Python library that could translate these into readable messages in a fun little script. I couldn’t find one, so I decided to build one myself. From there my little library grew into a full FT8 logging and enrichment tool.

**What my Project Does:**

* Parses WSJT-X UDP packets into clean Python objects
* Classifies all FT8 message types (CQ calls, QSOs, signal reports, acknowledgments, etc.)
* Tracks and organizes the state of every FT8 QSO from CQ to 73
* Translates messages such as "KWB8R KCQ4N R-08" into readable text: "KCQ4N says Roger and reports a signal report of -08 to KWB8R."
* Enriches data with frequency offset, MHz conversion, band detection, and more
* Performs Grid square lookups with lat/lon output and interactive map support (Folium)
* Exports

Potty - A CLI tool to download Spotify and youtube music using yt-dlp

Hey everyone!

I just released **Potty**, my new Python-based command-line tool for downloading and managing music from Spotify & YouTube using **yt-dlp**.

This project started because I was frustrated with spotify and I wanted to self-host my own music, and it evolved to wanting to better manage my library, embed metadata, and keep track of what I’d already downloaded.

Some tools worked for YouTube but not Spotify. Others didn’t organize my library or let me clean up broken files or schedule automated downloads. So, I decided to build my own solution, and it grew into something much bigger.

# 🎯 What Potty Does

* **Interactive CLI menus** for downloading, managing, and automating your music library
* **Spotify data integration**: use your exported `YourLibrary.json` to generate tracklists
* **Download by artist & song name** or batch-download entire lists
* **YouTube playlist & link support** with direct audio extraction
* **Metadata embedding** for downloaded tracks (artist, album, artwork, etc.)
* **System resource checks** before starting downloads (CPU, RAM, storage)
* **Retry manager** for failed downloads
* **Duplicate detection & file organization**
* **Export library data** to JSON
* **Clean up** broken or unreadable tracks
* **Audio format & bitrate selection** for quality control

# 👥 Target Audience

AskOra - one CLI to talk to OpenAI, Ollama, and more (without losing your mind)

**What My Project Does:**
AskOra is a Python CLI that lets you send prompts to multiple AI providers (OpenAI, Ollama, etc.) using the **same syntax**. It returns structured JSON responses including output, tokens used, and execution time. Works both sync and async.

**Target Audience:**
Developers who want a simple, unified CLI for experimenting with AI models. Good for scripts, testing, or tinkering with AI without installing a dozen different tools.

**Comparison:**
Unlike installing separate CLIs for each AI provider, AskOra lets you use one command for all. It also provides structured outputs and supports async calls, which most other CLIs don’t.

**Quick Example:**

askora --type openai --key YOUR_KEY --model gpt-4o-mini --prompt "Write me a haiku"

For Ollama (local model):

askora --type ollama --base-url http:/localhost:11434 --model codellama --prompt "Are you a good coder"

Python 3.13 REPL keyboard mappings/shortcuts/bindings

I couldn't find a comprehensive list of keyboard shortcuts for the new REPL, so here's the source code:

https://github.com/python/cpython/blob/3.13/Lib/\_pyrepl/reader.py#L66-L131

\\C means Ctrl, \\M means meta (Alt key on Windows/Linux, Option[?\] on mac).

Of particular interest, on the Windows 10 Terminal, pressing Ctrl+Alt+Enter while editing a block of code will "accept" (run) it without having to go to the end of the last line and pressing Enter twice. (Alt+Enter on Windows switches to/from full screen mode). on Ubuntu, it's Alt+Enter. i don't have a mac to test on -- if you do, let me know in the comments below.

How do you automate emails with Django?

Hello guys,

In my website I got a register form and I made it so that whenever I get a new registration (a new registry in my database) I will get an email so that I would check my admin panel.

First I used the standard Gmail SMPT 587, I set an App password and it worked locally just like butter, the emails were sent instantly.

But when I got to production (used Digitalocean) it stopped sending emails, or more precisely it keeps loading forever, it's like Django is trying to connect but can't. Chatgpt said that 'Some cloud providers block outbound SMTP ports (25, 465, 587) to prevent spam' and suggested that I switch to something like Brevo, I created an account and set up everything (port 2525) but I still can't send emails on registry. even though (unlike gmail smpt) I CAN connect to it from the server and CAN send emails from server but when I try to do it from my website it takes forever or crashes.

Any advice on what should I do or use differently ? and is there a good free option to it?
