Need advice!
A friend wants to learn python and then data science basics.
Which free online courses do you recommend?
They have a numerate degree so understand computation and statistics basics but didn't learn python nor the common python tools for data science.
Coursera? Udemy? Khan academy? I have no clue...

About 6 months ago I moved to #mastodon.
Thoughts comparing to Twitter...
Pros:
- more likely to get technical questions answered
- generally more sober or thoughtful political discussion
- higher adoption of alt text
- almost zero racism, sexism, and other hate
Cons:
- reach is tiny compared to Twitter eg for sharing events, tutorials, meetups
- not useful as a broad news feed
- no direct conversation with leaders of their respective fields, they're just not here
- retweets were useful

what is the most #linux and #bsd compatible laptop these days?
i mean hardware utilised optimally
eg, back in the day (1990s-2000s) we'd put up with
- storage not using UDMA falling back to basic speeds
- graphics hardware falling back to unaccelerated compatibility modes
- no network hardware offload
- suspend to disk but not ram
- no power mgt (apm vs acpi?) so battery draining fast
- weird sound drivers (oss/free)
- cleartype emulation / mimicry
- no way to update bios/firmware

Is this right?
My brain is telling me this is clearly not correct/complete. ... What am I missing?
4|2.8=16 and 4|8 but 4 is not prime ??

Next week I'll be doing a talk at #PyData Exeter ..
A Beginner's Intro to ROC Curves for Classifier Optimisation
Here are the slides (work in progress)

@npub1hxf…g8qu of course that's not excuse for government bodies using Microsoft's SaaS to hold and process sensitive information.
And you'd fully expect highly classified information not to be given to Microsoft or Google or anyone else's cloud.

@npub1hxf…g8qu as some comments have noted,
Microsoft's capability to secure its SaaS email is far greater than most organisation - the very very long tail of organisations from flower shops to metal factories, schools to charities, publishers to even most tech startups.
But quite a few determined groups have capability greater than the Microsoft bureaucracy.

currently listening to The Real #Python Podcast ep 189
I've never really been into coding podcasts but having tried this - it seems generally useful as passive listening and then paying attention to useful items.

initially I didn't like the idea of python virtual environments (my head is still 10 years in the past) but I can see they make sense when packages and combinations are so risky.
but common combinations just fail - even the very famous realpython's tutorials don't work !
and simple things like "upgrade all pip packages" seems like a difficult task.
still - I am grateful for the open source :)

After some years away ... I've been doing tutorials on #python frameworks like flask and sqlalchemy and connexion ..
.. omg, I forgot how bad python package management is !

My #algorithmicart YouTube channel is for beginners ..
it focusses mostly on ideas - from colour to recursion, from ray-tracing to fractals, from perlin noise to space-filling

Until recently I didn't know about the "distance estimation method" for rendering Mandelbrot and Julia fractals.
I'm still no expert but the idea is that the gradient of the orbit of z under z^2+c is higher closer to the set.
The traditional "escape" method can miss very fine sub-pixel details

Here is an example image rendered by very simple code:
