It's hard not to feel like the bar is lower. I feel like since Steve
Grandi retired at NOIRLab, I and Josh Hoblitt are the only people left who
actually understand how IP networks work. And I'm not great, never was,
but I know a lot more than...everyone else.
And kids these days, well, I'm not very fluent in TypeScript and I really
don't understand why every damn thing needs to be asynchronous especially
if you're just awaiting its completion anyway. But, hey, it ain't that
hard to do.
But again, there's a part of me that wonders how relevant the skills I miss
*are* anymore. I'm a software developer now, but I always thought of
myself as basically a sysadmin. It's just that we had automated away all
of what I started out doing (which was, what, 35-ish years ago?) by 20
years ago, and staying ahead of the automation has made me, of necessity, a
software developer now.
But I was also thinking of Larry saying he wouldn't last a week in today's
workplace, and I'm not sure that's true.
I mean, there's a lot of stuff that you once COULD say that would these
days get you a quick trip through HR and your crap in a box and a walk to
the curb...but I am a pretty foul-mouthed individual, and I have said nasty
things about people's code, and, indeed, the people who are repeat
offenders with respect to said code, and nevertheless I have had
surprisingly few issues with HR these last couple decades. So in some
sense it really DOES matter WHAT it is that's offensive that you're saying,
and I am living-and-still-employed proof.
If you generally treat people with respect until they prove they don't
deserve it, and you base your calumny on the bad technical decisions they
make and not their inherent characteristics, then it really ain't that hard
to get along in a woke workplace. And I say this as an abrasive coworker,
who happens to be a cis het white dude from a fairly-mainstream Christian
background and the usual set of academic credentials.
Let's face it: to do a good job as a software developer or generally an IT
person, you do not need a penis. You do not need to worship the way most
people at your workplace do. You do not need a college degree, let alone
in CS. You do not need to be sexually attracted to the opposite sex. You
do not need to have the same gender now that you were assigned at birth.
You do not need two (or given the current state of the art, ANY) working
eyes. Or hands. You do not need to be under 40. You do not need to be
able to walk. You do not need pale skin. And anyone who's saying shit
about someone else based on THAT sort of thing *should* be shown the curb,
and quickly. And the fact that many employers are willing to do this now
is, in my opinion, a really good thing.
On the other hand, if someone reliably makes terrible technical decisions,
well, yeah, you should spend a little time understanding whether there is a
structural incentive to steer them that way and try to help them if they're
trainable, but sometimes there isn't and they're not. And those people,
it's OK to say they've got bad taste and their implementations of their
poor taste are worse. And at least in my little corner of the world, which
is quasi-academic and scientific, there's a lot of that. Just because
you're really really good at astronomy doesn't mean you're good at writing
intelligible, testable, maintainable programs. Some very smart people have
written really awful code that solved their immediate problems, but that's
no way to start a library used by thousands of astronomers. But whether or
not they're competent software engineers ain't got shit to do with what
they have in their pants or what color their skin is.
And it's not always even obvious bigotry. I don't want to work with toxic
geniuses anymore. Even if the only awful things they do and say are to
people that they regard as intellectually inferior and are not based on
bullshit as above...look, I'd much rather work with someone who writes
just-OK code and is pleasant than someone who writes brilliant code and
who's always a quarter-second from going off on someone not quite as smart
as they are. Cleverness is vastly overrated. I'd rather have someone with
whom I don't dread interacting writing the stuff I have to interface with,
even if it means the code runs 25% slower. Machine cycles are dirt cheap
now. The number of places where you SHOULD have to put up with toxicity
because you get more efficient code and it actually matters has been pretty
tiny my entire adult lifetime, and has been shrinking over that lifetime as
well. And from a maintainability standpoint...if I encounter someone
else's just-OK code, well, I can probably figure out what it's doing and
why it's there way, way more easily than someone's code that used to be
blazing fast, is now broken, and it turns out that's because it encodes
assumptions about the runtime environment that were true five years ago and
are no longer correct.
That said, it's (again, in my not-necessarily-representative experience)
not usually the nonspecific toxic genius people who get in trouble with
HR. The ones who do, well, much, MUCH, too often, are the people
complaining about wokeness in the workplace who just want to be able to say
bad things about their coworkers based on their race or gender (or...)
rather than the quality of their work, and I'm totally happy to be in the
"That's not OK" camp, and I applaud it when HR repeats that and walks them
out the door.

There's another method of distinguishing UPenn from Penn State. Permit
me to share my favorite joke on the subject, from ten years ago.
"STATE COLLEGE, Pa. -- Construction workers tore down Penn State's
iconic Joe Paterno statue on campus two years ago -- but this town might
not be without one for much longer.
Two alumni already have received the OK from the borough to install a
projected $300,000 life-sized bronze sculpture downtown, about two miles
from the original site." -- ESPN ([1])
"The key difference is that the new statue will look the other way."

Certainly it's a step up (and a BIG step up) from assembly. But I'd say C
is a step sidewise from Fortran. An awful lot of HPTC programming involves
throwing multidimensional arrays around and C is not suitable for that.

It gets very tricky when routine libraries are involved. Just figuring
out the compilation order can be a real bear (part of this is the cross
object code type checking you mention).
From my viewpoint Ada suffered two problems. First, it was such a large
language and very tricky to implement--even more so than PL/I. Second, it
had US Government cooties.

I see this as related to the old question about whether it is easier to
teach domain experts to program or teach programmers about the domain.
(I worked for a company that wrote/sold scientific libraries for
embedded systems.) We had a mixture but the former was often easier.

I think this is a common problem when learning Go, like assigning
getchar()'s value to a char in C. It was back in ’14 anyway, when I saw
https://www.qureet.com/blog/golang-beartrap/ which has an ‘err’ at an
outer scope be unwritten by the ‘:=’ with the new, assigned-to ‘err’
going un-checked.
The author mentions ‘go vet’ highlights these cases with -shadow, which
is off by default.
https://pkg.go.dev/github.com/golangci/govet#hdr-Shadowed_variables
suggests that's still the case.

Regarding C and C++ having dangerous language features--of course they do.
Every higher-level language I've ever seen has its set of toxic language
features that should be avoided if you want reliability and maintainability
for your programs. And a set of things to avoid if you want portability.
Regarding managed dynamic memory allocation schemes that use garbage
collection vs. malloc()/free(), there are some applications where they are
not suitable. I'm thinking about real-time programs. You can't have your
missle defense software pause to do garbage collection when you're trying
to shoot down an incoming ballistic missile.
