cs_throwaway··on Why MIT switched from Scheme to Python (2009)
It is possible that this doesn't work anymore.

I distinctly recall the following episode when I last taught intro CS in Scheme: I revealed first-class functions. After lecture, the brightest kid in class came up to me and said something to the effect of, "What's the big deal? You can do this in Python."

cs_throwaway··on Reflections on 2 years of CPython's JIT Compiler
Do you think it may be feasible to do this and maintain the FFI?
cs_throwaway··on The Academic Pipeline Stall: Why Industry Must Stand for Academia
> It seems like no more than a year ago the prevailing narrative was problems with higher education and science: how predatory and insidious the student loan industry is, and how it traps people in a cycle of debt with special treatment from the government to not let them escape; the replication crisis revealing just how deeply flawed the incentives in science are, and how safeguards like peer review have failed to stop the slide.

All that is true, and fewer people should be pushed into pointless colleges.

ACM SIGOPS/SIGARCH does not represent that. This is a group of people doing fundamental work on computing systems, microprocessors, etc. They are largely at very technical schools, and lamenting that they won't be able to pay for PhD students -- who do not take loans, debt, etc.

(CS PhD students are paid well enough and have amazing post-PhD/dropout-PhD opportunities. Happy to have that argument.)

> Every day at class I would keep a tally of how many lies and incorrect statements and explainations would get made every day.

In your computer science classes? What/where were you studying?

cs_throwaway··on The Academic Pipeline Stall: Why Industry Must Stand for Academia
We in computer science departments are very happy to send our students to industry, whether or not they bother finishing their degree.

The article lists a bunch of old-timers, like Page and Brin. Right now, everyone is talking about the "$100M offers" from Meta, for people who completed (or dropped out) of their computer science PhDs.

What does "not standing for industry" mean to you?

cs_throwaway··on Apptainer: Application Containers for Linux
Funny this is here. Apptainer is Singularity, described here:

https://journals.plos.org/plosone/article?id=10.1371/journal...

If you ever use a shared cluster at a university or run by the government, Apptainer will be available, and Podman / Docker likely won't be.

In these environments, it is best not to use containers at all, and instead get to know your sysadmin and understand how he expects the cluster to be used.

cs_throwaway··on Computer science has one of the highest unemployment rates
CS professor with 15 years experience.

The massive boom in computer science enrollment over the last 20 years has been driven mostly by people chasing tech salaries, not by any real interest in computing itself. These students often show up completely unprepared for how difficult CS actually is, and universities have responded by dumbing down their programs to keep everyone happy and enrolled.

If this weeds out the people who are just there for the paychecks, it might actually be a relief to get back to teaching students who genuinely want to learn about computing.
