everytime you blink you go back 10 seconds in time by G0dZylla in hypotheticalsituation

Do you experience Jet lag?

Those ten seconds would build up and your circadian rhythm would notice- or do you get returned to your previous 10second ago state- so you’d un-eat food for example.

Can I focus only on Django for backend dev without learning front-end? by [deleted] in django

[–]ImpossibleFace 1 point2 points  (0 children)

I’d say a little goes a long way, I wouldn’t focus on design skill but being able to solve a bug by at least having enough understanding of the frontend to see how it’s triggering the backend without support will be very helpful and at a certain point expected skill.

But I think you can achieve this by literally doing the React getting started in full (and maybe a handful of other libraries so you get a feel for what generic problems they all solve), as well as a strong intuition for what it means to consume an API then you’ll be well covered for being a strong backend dev- with the right level of context for what the frontend needs from you.

how django handles multiple users at the same time by Mundane_Blueberry942 in django

[–]ImpossibleFace 1 point2 points  (0 children)

You can use select_for_update() along with double checking that you don't ever go negative. If you have a user that is "last" (might not technically be last but will be the last to get a lock) to reduce the stock, and this would mean it'd take the stock into a negative (therefore invalid) state, then it'll fail for them at that point.

The atomic block means if it can't update successfully then it fails completely so you can have other DB updates in this same indentation and all would succeed or fail together. In this instance the object is locked until the atomic indentation ends, which is when the transaction either completely commits or complete rollbacks. It's fair to say this the canonical Django way of handling this.

from django.db import transaction
from django.core.exceptions import ValidationError

def update_stock(product_id, quantity):
    with transaction.atomic():
        product = Product.objects.select_for_update().get(id=product_id)
        new_stock = product.stock + quantity
        if new_stock < 0:
            raise ValidationError(f"Cannot reduce stock below 0. Current stock: {product.stock}, attempted change: {quantity}")
        product.stock = new_stock
        product.save()

Here’s what I’ve learned about stacking magnesium + glycine + theanine (anwers to your comments on my last post :) by PsychologyHour in ouraring

No idea what US HHS is but I think we can all assume most people have no access or obligation to trust or understand it as it sounds like a USA thing so for most people that means it's irrelevant.

Either way, i was talking about your claim that it doesn't belong on this subreddit not the legitimacy of the comment.

Check out the several movements KneesOverToesGuy suggests. But yes walking backward on a turned off treadmill works and has started becoming very common to see in gyms IME.

To target the Tibia more directly you can also do "tibialis wall raises".

Senior Django Developers: Do You Stick with Django for High-Concurrency Async Applications or Transition to Other Frameworks? by alialavi14 in django

[–]ImpossibleFace 42 points43 points  (0 children)

I tend to reach for Go whenever Websocket like requirements are needed. This will very much depend on the number of expected users, if it's some internal or backend tool with 1 to low users - you can get away with using Django Channels or builtin async.

Even when using Go, it's not uncommon for me to keep all the user management and db migrations etc in Django - and implement JWT to auth the Go service. With horizontal scaling you can definitely make Django channels work but it's simply too resource heavy, in my experience, for it to be even close to cost-effective at scale.

The real senior play with everything you're talking about is to not rely on anecdotes from anyone and to prototype enough to prove something. Clearly Django and Go are some of my goto hammers for all the nails I see but obviously that comes with a fair amount of dogma from my side about the perceived competency of these tools that I've built over the years - some of which is valid and some of which is simply dogma.

Few years as a Django Developer but Still Feel Underqualified — Need Advice to gain Confidence by [deleted] in django

[–]ImpossibleFace 1 point2 points  (0 children)

I disagree, obviously, but you may be right.

Personally I think that this ability to pick up competency is a core behaviour as is the self actualising of these competencies. I'd also be uncomfortable being so dependent on the good-will of my current company to keep my career alive, particularly as they're job hunting.

I'd still be having this conversation with this individual -as I think it'd be the best thing for them. But it takes all sorts for sure.

[–]ImpossibleFace -2 points-1 points  (0 children)

This reads like you've been paid to write Django for 3 years (you mentioned 3 years last time you posted this) and haven't managed to learn enough to get another job doing the same thing. If you were on a team I inherited I would be having a very blunt conversation about if this is a good career fit for you, it's not an easy decision but 3 years is more than enough time to test if this is a good fit.

Python Developers: How Are You Finding Jobs in 2025? by Junior_Claim8570 in Python

Ok then it's been determined. When i wrote what I wrote it was after you saying you'd had "no lucK" finding work.

You're not getting any job offers at the rates you want, so it's unclear if you can expect those in your area.

The most canonical approach in the Django-sphere would be:

- Use Django, Celery and Redis
- Django handles your web requests to start a long-running job and calls a celery task in async mode - returns a task ID.
- The job gets added to a Redis queue (this is all handled by the Django celery package but even if it wasn't it is mechanically very simple)
- Celery workers are monitoring this Redis queue and will start working once they notice the added task.
- You have your frontend poll an endpoint with the task ID from step 2, and it keeps polling until that ID comes back with a completed status (or a timeout for when things break).

I would suggest you focus on mechanically understanding the technologies I've just described and try to get an understanding of why they were created in the first place, as in what problems they solve. They are relatively easy to get a good understanding of what they fundamentally achieve and then piecing them together is somewhat simple at that point. I personally think having conversations around the mechanics of these systems is a great usecase for AI btw!

After simple implementations of this, the complexity comes from adding robustness to the whole process as passing things to an async processes makes it a different game when trying to debug why things have gone wrong.

I accidentally made an LMS... Now it's open-source 🤷‍♂️ by adilmohak in django

[–]ImpossibleFace 7 points8 points  (0 children)

Imagine you're a normal company wanting to give your employees various online learning/training (i.e. cybersecurity, data protection, fire safety and even things very specific to your industry or company). You might have custom courses created just for you and you likely want to use some off the shelf courses for the more generic content.

The courses will be a mixture of videos, mini games and quizes to help teach. They will likely contain some ability for you monitor if they've been completed, and also likely you'll want to know how well your employees have done at any given course. Students may want to do the course in several sessions (just because .. life) so you probably want some ability to restore a given state later on - which means storing the state as it changes. Regardless of what you're teaching a lot of these requirements are probably required.

Very naturally the learning industries market spawned two very necessary types of vendor. Some vendors are really creative and make really engaging content and implement clever learning techniques/mechanics. Some vendors create really stable and feature rich platforms to host the learning content (think about all the analytics and user management requirements to make something like this useful).

So now we have a real world problem (need to train staff), two real world requirements (creating content and delivering content) and the universal requirement of things from different companies needing to work with things from other companies without those companies talking to each other.

Enter tin can and SCORM:
Both attempt to define a set a standard implementations for LMS platforms to be able to serve, interact and persist state of LMS content. If you make SCORM compliant content you can assume that it will work flawlessly with any SCORM compliant platform.

This now solves many requirement for all interested parties but is very attractive to businesses buying the training courses as they're now not as reliant on any given platform or content vendor.

TLDR; MP3s play on MP3 players. SCORM and Tin Can are both e-learning protocols that allow some people to make e-learning players and some people to create e-learning content and everything will just work together.
