leblancfg··on J.C. Penney’s troubles are reflected in satellite images of its parking lots
Of course one of the axes has been scaled. We're interested in the proportionality between the two variables, to see how good their claim that cars parked is a good proxy measure for stock price. I see where "percent since arbitrary start time x" is a poor choice of units for cars, but since it's a linear transformation, you'd get the same picture (and conclusion) were you using "thousands of cars" instead.
leblancfg··on A Conceptual Introduction to Hamiltonian Monte Carlo
Great talk, thanks for the link!
leblancfg··on Learn Python 3 the Hard Way
I'm not sure I get that. Care to elaborate, and what use cases you have for it?
leblancfg··on Mulesoft files for IPO
Because the other really kicked the llama's ass, of course!
leblancfg··on Gently Advise HN: Flexport hiring posts need this chance to go meta
I gently agree with the "links to random articles about Flexport instead of actual job listings" part. Otherwise it feels like HN is experimenting with running ads.
leblancfg··on Using Vim as a Python IDE
Yup! There are in fact quite a few similar vim plug-ins that do the same.

This is one of the longest-standing line in my vimrc so far:

    Plug 'epeli/slimux'
Works best for what I do.
leblancfg··on Show HN: Command Line Challenge
You are: grep matches strings, not integers.

    grep -rl '500'
works just fine.
leblancfg··on Amazon's Alexa Moves in on Google's Android System
Good point. Is anyone aware of a FOSS implementation of "personal audio assistants"? Because the Orwellian creepy factor is way up there.
leblancfg··on SpaceVim – Like Spacemacs, but for Vim
Tried Spacemacs 3-4 times because of org mode. Most specifically inline code block execution, through org-babel. Still not ready to change over from vim, though.

What I haven't done is check neovim. Any comments regarding the potential for inline code execution?

leblancfg··on Classes Considered Harmful [pdf]
Although he spends quite some time on exploring the alternatives, the only reason the author specifically states where classes are harmful is because they are premature optimization. That's it?

I guess "Classes considered a PITA" just didn't make a good title.

leblancfg··on μWWVB: A Tiny WWVB Station
Great stuff! I should add, "10s of nanoseconds" took a while to digest. Can I suggest "tens" instead?
leblancfg··on Tool AIs want to be agent AIs
Glad to see this articulated so well. The 'Overall' paragraph sums up thoughts that had been in the back of my mind for months. Plus, hey, it's Gwern. If you're reading this: you're an inspiration, man.

What is still unclear -- to me at least -- is the technical challenges that lie ahead of this "neural networks all the way down" approach. I get the impression we'll need quite a few breakthroughs before usable Agent AIs are a thing. Insights on the order of importance as, say, backpropagation and using GPUs.

leblancfg··on Talks that changed the way I think about programming
Yup, that talk is gold. He's started producing screencasts again, and live streaming some on twitch. https://m.twitch.tv/gary_bernhardt/videos/all
leblancfg··on HDEV: High Definition Earth-Viewing System
That sounds really nice. Would you care to share your code?

leblancfg··on Automated Inference on Criminality Using Face Images
I am just as shocked and appalled that it's getting upvoted. It's so un-scientific, it should be taught in class as a counterexample.
leblancfg··on Decrypt all authorization tokens on macOS without user authentication
Thanks for the update!
leblancfg··on Decrypt all authorization tokens on macOS without user authentication
At first glance, this seems irresponsible from the part of the author. Contact Apple first and let them know, only release your repo if you don't get an answer, and make sure to let the world know in your README.md.

The engineers at Apple are just as human as you are.

leblancfg··on Org mode 9.0 released
Breaking backwards compatibility happens, and I don't see it as too much of a threat to the project.

What might be nice is, for every release, to provide a script that would update your org files to the current standard.

Maybe such files even exist, but they would need to be closer to the users' hands.

leblancfg··on Pre-Safe Sound: Playing ‘pink noise’ in the split second before impact (2015)
The sound is distinctly crisper on BigQuery, though. Of course, cables can make a difference but not always -- use CAT-8.2 if possible.
leblancfg··on Understanding Aesthetics with Deep Learning
I agree. Although one could imagine that concepts conveyed in a photograph could be extracted and abstracted as vectors -- just like word2vec and its successors. Of course, there is a long way to go before we hit "human understanding" parity, but I think ideas from [1], [2] and [3] could be extrapolated in doing just that.

leblancfg··on Ask HN: What cool development languages/tools changed your career?
I guess that's not tooo surprising, given the backronym "Practical Extraction and Reporting Language".
leblancfg··on Ask HN: What cool development languages/tools changed your career?
3 months into vim and I'm only starting to get better productivity than what I had in my old editor, PyCharm.

It's fine to learn the basics, but the hard part for me was to internalize not only the movements, but striving to use the smallest amount of keystrokes for any given edit. Always keep learning!

Turns out, there are also a bunch of extensionless files in there, too.

  for file in *; do if [ -f $file ] && [ ${file:(-3)} != "pdf" ]; then mv "$file" "${file}.pdf"; fi done

Anything outside the US?
leblancfg··on Virtual Forest
Great stuff! I'm a little frazzled by the fact that you're leaving 350$ cameras in the woods unattended, though. Figures they're not too far from your home given the CAT5 length you mention, but for anyone interested in building one in a more remote location (IoT SIMs with decent data plans are a thing now!), you might want to consider camouflage, and/or setting up in a tree.
leblancfg··on The most notable luminaries of our time are wrong to fear AI
Dear Input Coffee,

First off, I would feel very uncomfortable contradicting Elon Musk, Bill Gates, Stephen Hawking and Bill Joy in one fell swoop. Who am I to judge, though. Argument from authority can be fallacious, sure, so let's not go there.

Think about this for a minute. By the same argument you're taking, we are just lumps of organic molecules replicating with DNA, surely we can't feel anything, right? The thing you're not considering here is emergent behaviour.

Now, you haven't talked about self-programming machines in your article, and I'm pretty sure that's what all the really smart people you've rebuked in your subtitle are scared of. Do a quick Google search for "self-programming" AND "machine learning" AND "genetic". If you've read Dawkins' The Selfish Gene, you should be getting goosebumps right about now. If not, and are interested in AI in any way, I cannot stress hard enough how badly you need to go out and get that book.

I was also surprised to see you didn't include Nick Bostrom's book called Superintelligence (2014) in your quotes. If you haven't check it out, I would highly recommend it. It goes deep and wide into how a sudden, exponentially growing spike of machine intelligence could impact our society.

leblancfg··on How to Write a Spelling Corrector
Couldn't it cause issues with "object definition" code in REPLs and editors, and interfere with documentation generators, i.e. [Sphinx](http://www.sphinx-doc.org/en/stable/)?
leblancfg··on How to Write a Spelling Corrector
Came here to say this. I've combed through his pieces many times over just to glean the way he structures his code. Here, he got my head spinning for a minute with

  return set(w for w in words if w in WORDS)
and made a mental note to use that idiom in the future.

As for doc strings, well, this is just a toy piece of code after all. The main purpose for the code is to be read, instead of actually used. something something hobgoblin of little minds

Edit: formatting.
