How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

About This Manifesto

Have you ever argued for or against teaching language X as the first language in a university computer science curriculum? If so, I hope that your arguments:

• were first and foremost about students, considering the question “What do we want students to gain from their experience with a first language?”, not “Is language X better than language Y?” because the latter question requires too much context and isn’t really answerable;
• kept in mind that ultimately we want to train polyglots, so the first language is never the only language; and
• took into account previous work from computing educators, and education theorists and practitioners in general.

user-package-stats

I was poking around trying to figure out all the packages I have access to publish and got curious. So I write this little script to determine the download stats for all the packages I have publish access to.

Feel free to try it yourself. Just change the username passed to getUserDownloadStats.

By default, the stats are sorted by their average daily downloads (descending). That should give you an idea of the most "popular" package of a given user relative to how long that package has been around.

You can use it with npx like so:

    default: Turndown
}, {
    default: Readability
}]) => {

  /* Optional vault name */
  const vault = "";

  /* Optional folder name such as "Clippings/" */

How much prep did you do for the technical interviews?

I get asked this a lot so I thought I'd write it up to share. For context, I was interviewing for staff+ individual contributor roles at tech companies.

Technical Interviews

I was preparing to do some amount of live coding interviews, and some amount of pairing interviews.

Tech setup check-in

My friend Tom offered to do a pairing interview with me, which I also used to check my Zoom / screenshare setup. I screen shared from my 2019 XPS 13 for the pairing, but also had Zoom on an ipad for video/audio. I used Airpods for audio. This setup actually worked great, but it was nice to dial in some of the specifics--mic feedback from dialing in from two places, and just practice my schpiel about explaining what I was doing to the other person. Probably not useful for you unless you too, have Linux problems.
