whereproc: a small CLI that tells you where a running process’s executable actually lives

I’ve been working on some small, practical command-line utilities, and this one turned out to be surprisingly useful, so I packaged it up and put it on PyPI.

What My Project Does

whereproc is a command-line tool built on top of psutil that inspects running processes and reports the full filesystem path of the executable backing them. It supports substring, exact-match, and regex searches, and it can match against either the process name or the entire command line. Output can be human-readable, JSON, or a quiet/scripting mode that prints only the executable path.

whereproc answers a question I kept hitting in day-to-day work: "What executable is actually backing this running process?"

Target Audience

whereproc is useful for anyone:

debugging PATH issues
finding the real location of app bundles / snap packages
scripting around PID or exe discovery
process verification and automation

Comparison

There are existing tools that overlap with some functionality (ps, pgrep, pidof, Windows Task Manager, Activity Monitor, Process Explorer), but:

- whereproc always shows the resolved executable path, which many platform tools obscure or hide behind symlinks.
- It unifies behavior across platforms. The same command works the same way on Linux, macOS, and Windows.
- It provides multiple match modes (substring, exact, regex, command-line search) instead of

how obvious is this retry logic bug to you?

I was writing a function to handle a 429 error from NCBI API today, its a recursive retry function, thought it looked clean but..

well the code ran without errors, but downstream I kept getting None values in the output instead of the API data response. It drove me crazy because the logs showed the retries were happening and "succeeding."

Here is the snippet (simplified).



def fetchdatawithretry(retries=10):
try:
return apiclient.getdata()
except RateLimitError:
if retries > 0:
print(f"Rate limit hit. Retrying... {retries} left")
time.sleep(1)

fetchdatawithretry(retries - 1)

Flask-Security vs a la carte (login, authorize, dance)?

I've used flask-login for many years, bolting on my own roles/permissions system, email authentication, password management, etc. Am looking to finally make an upgrade to some standard tools, but am having trouble deciding between the all-in-one pallets project flask-security and an a la carte approach with flask-login, flask-authorize, and flask-dance (plus probably others).

Have you used either stack? What did you like/dislike about it?

Why do we repeat type hints in docstrings?

I see a lot of code like this:



def foo(x: int) -> int:
"""Does something

Parameters:
x (int): Description of x

Returns:
int: Returning value
"""

return x


Isn’t the type information in the docstring redundant? It’s already specified in the function definition, and as actual code, not strings.

PyTogether - Google Docs for Python (free and open-source, real-time browser IDE)

For the past 4 months, I’ve been working on a full-stack project I’m really proud of called PyTogether (pytogether.org).



# What My Project Does

It is a real-time, collaborative Python IDE designed with beginners in mind (think Google Docs, but for Python). It’s meant for pair programming, tutoring, or just coding Python together. It’s completely free. No subscriptions, no ads, nothing. Just create an account, make a group, and start a project. Has proper code-linting, extremely intuitive UI, autosaving, drawing features (you can draw directly onto the IDE and scroll), live selections, and voice/live chats per project. There are no limitations at the moment (except for code size to prevent malicious payloads). There is also built-in support for libraries like matplotlib.

Source code: https://github.com/SJRiz/pytogether



# Target Audience

It’s designed for tutors, educators, or Python beginners.



# Comparison With Existing Alternatives

Why build this when Replit or VS Code Live Share already exist?

Because my goal was simplicity and education. I wanted something lightweight for beginners who just want to write and share simple Python scripts (alone or with others), without downloads, paywalls, or extra noise. There’s also no AI/copilot built in, something many teachers and learners actually prefer. I also focused on a communication-first approach, where the IDE

Can someone post an example of a flask app that has blueprints with multiple models.py in each blueprint folder using the current working version of flask with html as the front end ?

I am getting an error in my flask app rather then posting my long convoluted error I figure I would try to see if there something wrong with my app by seeing an working example of a flask app with html as the front end with blueprints with multiple models.py files in each blueprint folder using the current working version of flask. Does anyone have working example ? Could someone link there github or something else?

My web app was working before the multiple models.py files.

Looking for a sanity check on an interview assignment

Looking at a new position, with a mission I do care about, but just got their take-home assignment and I am having some 2nd thoughts. I'm mostly a low-level engineer, HPC modeling and simulation and signal processing and the employer knows this. And this sort of thing isn't as the position was described.

I assume this is their standard question, regardless of the candidate:

-----

Please write code to download the current dataset, store the data server-side, create APIs that can retrieve the server-side stored data, and provide a UI to analyze it for items such as word count per department, historical changes over time, and a checksum for each department.

Only implement analysis that would provide meaningful information to the user.

Please add at least one custom metric that you believe may help inform decisions more effectively.

----

Without environment setup, they designed this to take under 6 hours. I can see it taking that long for someone who does this sort of thing every day currently, but with my background, this is completely different.

Just looking to see if I am off-base in my assessment that this is way more than 6 hours of work or if they simply expect me

TerminalTextEffects (TTE) version 0.13.0

I saw the word 'effects', just give me GIFs

Understandable, visit the Effects Showroom first. Then come back if you like what you see.

If you want to test it in your linux terminal with uv:

ls -a | uv tool run terminaltexteffects random_effect

What My Project Does

TerminalTextEffects (TTE) is a terminal visual effects engine. TTE can be installed as a system application to produce effects in your terminal, or as a Python library to enable effects within your Python scripts/applications. TTE includes a growing library of built-in effects which showcase the engine's features.

Audience

TTE is a terminal toy (and now a Python library) that anybody can use to add visual flair to their terminal or projects. It works in the new Windows terminal and, of course, in pretty much any unix terminal.

Comparison

I don't know of anything quite like this.

Version 0.13.0

New effects:

Smoke

Thunderstorm

Refreshed effects:

Burn

Pour

LaserEtch

minor tweaks to many others.

Here is the ChangeBlog to accompany this release, with lots of animations and a little background info.

D How to transition to industry after an AI/ML PhD

Hey Folks!

Feeling anxious, confused and thought to reach out for some advice here.

I am 1.5 yrs out of finishing a PhD in AI/ML from USA but do not have stellar publication record.

I'm in mid thirties and kind of drained out of the whole PhD experience.

Any suggestions as to what roles I can look into to transition to full time if I am not keen on grinding out leetcode (not averse to doing leetcode but just do not want to grinding it out as a mid 20s person) and okay with a decent salary?

Using Claude Code CLI with Django: What’s in your claude.md?

Hi everyone,

I’ve recently started using the Claude Code CLI for a Django project, and I’m trying to optimize the claude.md context file to get the best results.

For those using it, what specific instructions or project context have you added to your claude.md to make it work smoothly with Django's architecture?

Currently, I’m considering adding rules like:

1. ORM Preference: Explicit instructions to prefer the Django ORM over raw SQL or Python-side filtering.
2. Style: Enforcing Function-Based Views vs Class-Based Views.
3. Testing: Instructions to use pytest-django instead of the standard unittest.
4. Exclusions: Reminding it to ignore migrations/ files unless specifically asked to modify schemas.

Has anyone curated a "Golden Standard" claude.md for Django yet? I’d love to see examples of how you describe your apps/structure to the CLI.

Thanks!

How much energy does the internet use? A conversation about Django and digital sustainability

Hi all! I'm a software engineer and I’ve been getting more interested in the environmental impact of the software we build and the energy it takes to keep the internet running.

I recently recorded a conversation with Thibaud Colas, who works on Wagtail and Django and has been pushing for more awareness around digital sustainability. We talked about how much energy the web actually uses, how we can measure it, why performance ends up being an emissions issue, whether rewriting everything in Rust is the magic fix (spoiler: not really), and what kind of accountability we should expect from AI companies and cloud providers.

If you’re curious, I'm posting the link to the episode below. Happy to hear thoughts, feedback, or other perspectives from folks in this community!

Because of that, I ended up losing touch with the more popular mainstream solutions like Shopify, WooCommerce, etc.
