In this week's episode(https://embedded.fm/transcripts/447), we talked about ESP chips among other things. Here's an interesting excerpt:

CG (28:46):
The H2 is one of their new 802.15.4 chips. So that can run Thread and ZigBee, and they're getting big into Matter. And, that is, I believe RISC-V. And I think all of them have kind of a low-power RISC-V part as well.
CW (29:07):
It's funny, because I keep seeing ESP parts being taped onto low-power parts as the Wi-Fi.
CG (29:15):
Yeah.

Some thoughts to flesh out later, based on my attempts to make sense of some other researchers' work:

1. Working on probabilistic computations for statistical problems (e.g. Bayesian inference), it is often useful to have access to MAP estimates, for e.g. initialisation of other algorithms, even if you do not yourself care for point estimates statistically.

2. In situations where additional information is valuable (i.e. an idea of scale, and not just location), fitting parametric approximations via minimisation of the Kullback-Leibler divergence can be a nice way to systematically extract some extra information.

3. Even when optimisation algorithms for fitting such approximations are written in terms of variational parameters, they can often be connected back to conventional optimisation algorithms for point estimation by framing them in the mean parametrisation.

4. By way of tempering, etc., many algorithms for fitting such approximations can even recover classical optimisation algorithms directly, in appropriate limits. Working in the mean parametrisation tends to elucidate this analogy.

5. Working backwards, it is often possible to 'decorate' classical optimisation algorithms at mild additional cost so that their output is not just a point estimate, but a posterior approximation as well.

One perspective: estimation algorithms needn't be great distribution estimation algorithms, but they're often not too far off.

A safety check: one shouldn't generally expect distribution estimation algorithms to out-perform point estimation algorithms for { point estimation / optimisation }. Still, they can provide some extra intuition and context.

Check out my new (in-progress) book designed to teach literally *anyone* the basics of programming with Python.

ol boy charging $42K/mo to sell my tweets (along with everyone else’s) doesn’t sit right in my spirit, so i went ahead and deleted the app from my phone today. mastodon isn’t quite there yet for my purposes (Black twitter has largely stayed on twitter and that energy is sorely lacking here), but it’ll have to do for now.

After a lot of thought, I have decided not to learn or change anything, because that would be hard

Anecdotally I've heard people say they're surprised by how many job applications never get *any* response, not even a rejection.

Seems this is part of why: companies are posting fake job openings to mislead investors, employees, and competitors.

Last night, the Oxide Friends joined @bcantrill and me to tackle the topic: Does a GPT future need software engineers?

Spoiler: yes! and there's a lot of optimism about the ways GPT can be additive in particular to creative endeavors.

Thanks to @jmc, @ag_dubs, Keith Adams, and everyone who participated or joined us live!

Amazing how quick a lab bench turns into a total disaster when you're in the thick of debugging something!

But I think I've figured out my problem finally. Maybe.

IMO, relative to comments, religiously putting information in bug reports is underrated.

One company I worked for did this and it was fairly easy to see why any piece of code was the way it was because you could look up the history in bug reports.

There was no concern about comments getting out of date because you knew the exact date each comment was made and, for some reason, it seems easier to create a culture of filing tickets for changes than one of always updating the associated comment.

Didn't know this specific reasoning for the term 'splines' in regression, but it makes a lot of sense!
