For those who are self-taught, exactly what topics did you learn to get your job?

Im a 100% self-taught, beginner in learning python, and this is my first ever brush with anything computer science-related. I would love to become a jr software developer in the next 1-2 years (preferably back-end but am obviously willing to try anything), but im lost on what to learn. I understand the best way to learn is writing code aka doing projects, but what do i LEARN first to get to that point?

Right now, im still in the middle of Automate the Boring Stuff. I do practice problems the book has as i learn each topic (practice projects). Some have advised me to learn data structures next. Im lost on what to learn after data structures, and what to learn after that. What topics should I be studying next to at least get my foot in the door for an interview in the future?

​

Does anyone have advice on general roadmap of topics to learn that would help me have a solid understanding? Each topic/skill i do, i will be creating mini projects as i learn, but my main issue is, what do i learn? For those who started a job as jr developer or even internship, what

[D] ECCV 2020: paper summaries and highlights (blog post)

Hi;

I thought I write a blog post where I highlight some of the things that caught my attention while browsing this year's ECCV conference. The blog post contains summaries of some papers (and the mention of some) that I thought were nice (note: this is just a sample, I certainly missed a lot of cool ones).

The post might be helpful to get a general feel of this year's conference quickly since the number of papers (>1.3K) can be overwhelming at times. Check it out!

[P] Vulkan as an alternative to CUDA in scientific simulation software - computational magnetism

This is a continuation post to the [VkFFT announcement](https://www.reddit.com/r/MachineLearning/comments/ia6gv1/p_new_vulkan_fft_library_vkfft_opensource/). Here I present an example of scientific application, that outperforms its CUDA counterpart, has no proprietary code behind it and is crossplatform - [Vulkan Spirit](https://github.com/DTolm/spirit). This is a fully GPU version of the computational magnetism package Spirit, developed at FZ Jülich. I hope this post can motivate other scientists (including machine learning researchers) to explore the world of Vulkan for scientific GPU computing, as right now it is heavily dominated by CUDA.

From mathematical point of view, simulation of a magnetic system in micromagnetics can be described as a system of differential equations ([LLG](https://en.wikipedia.org/wiki/Landau%E2%80%93Lifshitz%E2%80%93Gilbert_equation)) on a finite-difference mesh. Each cell's position is influenced by positions of its neighbors, material parameters, external effects and many other things. Successful iterative integration of the LLG system can yield time dynamics, resembling experimentally observed evolutuon of magnetics.

From the programming point of view, simulation software is simpler than the one that has to communicate with the user during runtime. There are no calculations performed on the CPU during the execution, so it is only used to create a command buffer before launch, which is not modified afterwards. Combining multiple iterations in a single command buffer significantly

If you are interested in learning Django, check out this guide.

When I was learning Django, I watched countless youtube videos but I never found a cohesive guide of how to start developing web apps with Django.

I have written a book to help beginners learn django web development. The first three chapters are free, see link below. If you find it useful after reading the preview, please consider buying my book. Thanks

[D] What are some good resources to practice machine learning interviews?

As titled, as a college student interested in this field, I always find it hard to find resources to prepare me for machine learning related interviews.

For typical SWE positions, you have a wide range of resources available, such as LeetCode, HackerRank, and some other website to find peers to practice interviews with.

Are there similar resources available for machine learning related positions?

(Or specifically tailored for ML interview preps)

django chart.js - Query to count all distinct values for particular colum

My goal is to create a query to group together unique 'charges' and count them. Then correctly implementing a for loop, the goal is a pie chart showing multiple slices, each individual slice showing the total count per unique charge.

Currently here is the pie chart https://imgur.com/a/11TLOdC
I would like this to instead show 1 large slice for DUI (2/3) and 1 small slice for Assault (1/3). I think its my query that needs revising, any insight would be appreciated.

# Models.py
class Arrest(models.Model):
number = models.IntegerField()
date = models.DateField()
charge = models.CharField(max_length=64)

# Views.py
def visuals(request):
data = []
labels = []
# Currently my query and maybe the root of the issue
queryset = Arrest.objects.annotate(Count('charge'))

for arrest in queryset:

Creating a pastebing using Flask

Hello, I am trying to use Flask and thought that a fun way to do that would be to try to implement a pastebin (something like [this one](https://dpaste.com/)) hosted on my own computer. I have started with this [tutorial](https://www.roytuts.com/upload-and-display-image-using-python-flask/) where I learned how to create a website on which I can upload images. Now I want to modify it such that a new sub-website is created everytime I upload an image, like a pastebin. But I have no idea how to do that. Could someone help me figure it out?

R kernel Jupyter nightmare

Hi thank you for your time,

macOS Catalina Version 10.15.6

2013 Macbook Air

I want to preface this post by saying two things.

1: I am trying to get this program up and running for school and have tried everything I know and understand how to do over the last 2.5 days.

2: Although I followed the instructions of the official IR installation route my computer did not recognize the package and just kept telling me it didn't recognize the phrase IRkernel or irkernel or almost anything else I tried. However, I do have R set up through the R developers download and through Anaconda. So I'm sorry if this isn't the appropriate forum for this but I really don't know where else to turn.

The basic issue I'm having is that I cannot get a jupyter notebook to run my R kernel, it just keeps saying connecting to kernel endlessly and will not allow me to run any code. I have included some screenshots of my jupyter notebook and my terminal window below.

Dynamic drop down list in Django admin

Hey guys, how is it possible to create a dynamic drop down list in Django admin for exemple country and city. Let’s say you have a model for an event, and you have to chose the country and the city from which the event is taking place in Django admin, and making sure once the country is selected, we will have the specific cities related to that country. It would have been easier if it had to let the end sure fill out that form in a template, but I’m still trying to see how this can be done in the Django admin page. Thanks already for your helps.

AutoScraper: A Smart, Automatic, Fast and Lightweight Web Scraper for Python

In the last few years, web scraping has been one of my day to day and frequently needed tasks. I was wondering if I can make it smart and automatic to save lots of time. So I made AutoScraper!

The project code is available on Github: [github.com/alirezamika/autoscraper](https://github.com/alirezamika/autoscraper/)

This project is made for automatic web scraping to make scraping easy. It gets a url or the html content of a web page and a list of sample data which we want to scrape from that page. **This data can be text, url or any html tag value of that page**. It learns the scraping rules and returns the similar elements. Then you can use this learned object with new urls to get similar content or the exact same element of those new pages.

I hope this project is useful for you and saves your time, too.I look forward to hear any feedback or suggestion.
