[D] Interview with the VP of Research at NVIDIA on ML Research & Research at NVIDIA

Hi All,

I run a non-monetised, ad-free podcast a service to the community where I interview my ML Heroes.

I had the privilege to interview one of the pioneers of the ML: Bryan Catanzaro about his journey into ML, Research at NVIDIA and beyond.

If you have any suggestions on how to improve the podcast or any guest recommendations, I'd be happy to take them. Hope you enjoy the interview!

Thanks!

My first django site

Happy to finally create my first project after picking up programming earlier this year. It's nothing special, but I'm glad to have made it here. There's a lot more to learn, so do give me some feedback and suggestions! I used django for the backend, and some basic JS, HTML and CSS for the front end. It's basically a student council management site so there's not much to it, but I'd love to hear some criticism and ways to improve it!

In ipyparallel, how does one reset the namespace of the engines without restarting them?

If I'm not mistaken, each engine in ipyparallel has its own persistent namespace. As a result, if I import some module **M** in **engine\_i**, kill the main process (client code), and finally modify **M,** simply restarting the main process (client code) will not be sufficient for the changes in **M** to be reloaded in **engine\_i**.

The most reliable way to solve that problem so far has been to kill/reset all engines, but it is really tedious as I have to make a lot of frequent modifications to modules that are imported to engines.

I've tried reloading/deep\_reloading modules in engines, using the magics %reset etc, but to no avail. Is there a trivial way to reset engine namespaces? I can't believe that all developpers working with ipyparallel constantly kill/restart clusters.

Thanks for your help.

PS: if farming reputation on stackoverflow is your thing, I've made a more detailed post [here](https://stackoverflow.com/questions/63968732/ipyparallel-what-is-the-most-reliable-way-to-clear-reset-engine-namespaces-with).

Python decorators

Hi, decorator are useful and quite simple to use, at the beginning they may seem a little complex, but once you get the way they work they can save you tons of time keeping the code in order, making it more readable, mantainable and flexible. Have a look at the code into this repo [GH repository](https://github.com/formazione/python_cheatsheet) and take a look at the video in this post [https://youtu.be/C62Nu4yFFsM](https://youtu.be/C62Nu4yFFsM)

Need to make a web app that shares info (through dashboards) and handles basic automation, but should be incredibly secure - is Flask the right tool for the job.

I figured I would make a Flask portal where clients could log in and access visualizations (tool I will use is Dash) of various sorts we need them to see.

Depending on the person logged in, this flask app would also allow some degree of automation to be done - I.e. the user just clicks stuff on the site and some code runs on the backend and executes the necessary results.

Given that I've always been itching to get into web development, the first thing that came to mind was Flask. But I'm not sure about the security aspect of things.

1. I will be hosting the flask app on an EC2 instance and fetching data from our prod DB essentially via an SQL connection - is this something that is generally completely safe, given the environment variables will probably be access keys to our DB
2. Is it possible to implement industry standard MFA mechanisms into the login process, say through OTPs or Google Authenticator
3. Some of the automation I have in mind will involve interfacing with AWS APIs, which again means the environment variables will need to be access and secret keys. Is this generally safe?

How to handle forever-incremental Models and setup Meta-Models?

Been trying to properly get started with Django on-off, but there are just some things I cannot work out. Been using Flask for smaller projects now with SQLAlchemy & Celery because it's way more straight forward. But now that I want to start building something bigger and focus on it, I wanted to get some – probably basic – questions out of the way.

Let's assume we're a bank. And we're making a model for `client`, `account` and `transactions`.

1. Because we're a bank, we do not want to rely on simply updating an `account balance` value, but evaluate the account's balance by evaluating every transaction that was ever made on said account to see how much the current value is. **Q:** after a while this gets quite big and takes long to compute; how do you *squash* to say "hey, this is the current value – calculated on Sept 1st – you only have to re-evaluate new transactions for said account starting Sept 1? Like how do we handle that on a database/model level and how do we run the task?

2. We have multiple `account` types a `client` can have, with various conditions (like monthly cost, max
