#poll Have you ever snuck an "easter egg" through code review?

@aeva I put a 418 “I’m a Teapot” response in the cdn code for the npm registry with the intent that only misconfigured clients would see it but instead it took down registry dot yarnpkg dot com (because I forgot some proxies include the implicit :443 port in their host header)

what would you call a git commit that can no longer be reached from any branch or reference (for example because you ran git commit --amend or git rebase), but that you can still get to from git reflog?

I've considered "orphan", "dangling", and "unreachable" but none of these seem right:

  • orphan has another meaning in git
  • dangling only refers to the "tip" commits
  • "unreachable" means that you can't reach it at all

would love a term that's already used, I don't like inventing terms

@b0rk in the vein of “unreferenced”, “unnamed”.

Core competencies are something I think about a lot. I love to dig into what makes companies or ecosystems or social groups tick. Especially when that core competency enables what they do:

McDonald's, for example, is a real estate company that happens to make burgers.

Walmart is a shipping logistics company that also sells things.

What other examples can you think of where the core competency of the company is such that the "thing" a company does falls out naturally as a consequence?

@hazelweakly 🤔 mcdonalds might be more of a "drop-shipping franchise investment income to real estate developers" platform than a real estate company in and of itself?

a few weeks ago, I told a bicycle mechanic that I had bailed on some hill on klickitat because I didn't think I could make it up

"caulk the wagon and float it" was the phrase I used 😂

"this bike could get you up any hill, kf" he said

meanwhile on reddit

@kf that block east of 33rd hurts to walk up, I cannot even imagine it with a bike

also: apparently that area used to be a rock quarry, if I'm remembering correctly from the "portland stair walks" book!

A jetlagged, maybe-silly thought: what if, instead of defining a language to compose wasm components (as in WAC), we took a page from pulumi/terraform CDK and exposed wasm component composition as a set of javascript APIs

isntitvacant,
@isntitvacant@hachyderm.io avatar

@yosh there’s nothing technically preventing it!

that said: partially because I’d want to leave the door open to wrapping the bindings in a richer native interface, & partially because it’s useful to point folks to one concrete language to reduce cognitive overhead

Today is my birthday!

If you'd like to do something for me for my birthday, would you please reply to this with—or by other means send me— something with colors you liked? Like an image or a video or a link. Music would also be acceptable if it gives you a strong synesthesiac association with color.

If this request confuses you, here are some examples of images with colors I found striking [Artists: Laurie Barmore, Vian Borchert, Erica Aurahack]. But your reply can be whatever colors you like.

Something that I find missing in almost every software company is this thing that I'm not sure I've seen explicitly called out anywhere, but I'm going to call it an Engineering Language.

https://hazelweakly.me/blog/engineering-language/

isntitvacant,
@isntitvacant@hachyderm.io avatar

@codefolio @hazelweakly Yep, 100% agreed — it’s all about recognizing that your company already has an ideolect, and that engineering needs to adopt it before it can hope to help steer it.

Naming is one of the most difficult problems in software, and it’s mostly because we think it’s a skill someone one engineer can be good at in isolation.

poll: how confident do you feel that you know what HEAD means in git?

isntitvacant,
@isntitvacant@hachyderm.io avatar

@b0rk I might be wrong about this – but HEAD is a symbolic reference to another reference, sort of like a pointer-to-a-pointer (like "void**"); git behaves differently based on what kind of pointer the outermost pointer is pointing to?

(i.e., if it's pointing to a pointer that is a branch, we're in "attached HEAD" mode and commits to HEAD change the value of the referenced pointer; if we're in "detached HEAD" mode the referenced pointer cannot be updated)

isntitvacant, (edited )
@isntitvacant@hachyderm.io avatar

@b0rk ... which I'm realizing means I don't have a mental model for what happens if HEAD points at a tag ref 😅

(Edit: a ha, it puts git into "detached HEAD" state. That makes sense, I suppose. Polymorphism!)

If I am at the Linux command line, and I have a .so, is there a way to just like… try to load it, and see if it succeeds. I wouldn't want it to do anything, just load it and either error or not error. It's really awkward to launch the .NET executable that loads this .so naturally, I want a simpler test

@mcc Could you run LD_PRELOAD=./path/to/lib.so /bin/ls? (That should preload the dylib, IIUC?)

poll: when you have a merge conflict, how do you prefer to handle it?

isntitvacant,
@isntitvacant@hachyderm.io avatar

@b0rk other: I find most merge tool UIs difficult to comprehend; it ended up being easier in the long run to edit in vim directly (“search for ====, examine context of change, merge”) and — like so many things involving git — it kind of became muscle memory?

isntitvacant, to random
@isntitvacant@hachyderm.io avatar

I may be repeating myself here, but — somewhere along the lines when researching the history of virtualization I came across the etymology of the term (which comes to us from optics)

but the “vir-“ part is shared with “virtue”; it’s the same “vir” as in “triumvirate”— meaning “man”. This comes from the PIE “wi-ro”, which was gave us the elided compliment prefix to “wo” in “woman”: “were”, as in “wereman” (& “werewolf”.)

so yes you are running were-tual machines on your computer

Check me here... I can't use require() if I'm in a JS module (ReferenceError) but I can't use import if I'm not in a module (SyntaxError)

How am I supposed to reliably load something if this file needs to be used in both contexts??? Losing my marbles

isntitvacant,
@isntitvacant@hachyderm.io avatar

@tekknolagi in vanilla node at least, you should be able to use dynamic import() syntax in a commonjs module IIRC. just not the static “import xyz from ‘foo’” syntax.

people have been asking for this one a lot, so: what are your favourite git aliases to set?

isntitvacant,
@isntitvacant@hachyderm.io avatar

@b0rk to my intermittent regret, I aliased “ci” to “commit”, “co” to “checkout”, and “st” to “status” back in 2008 or so — I believe that I was mimicking subversion command shortcuts.

I mostly keep them around because of muscle memory at this point, which means I trip on my shoelaces whenever I try to use git inside a VM.

(It was a useful, formative lesson on the potential long-term downsides of adopting an idiolect, though!)

b0rk, (edited ) to random
@b0rk@jvns.ca avatar

does anyone know where the name HEAD for the current revision came from / what the rationale was? I think that git copied it from Subversion/CVS, but it seems like such a weird name and I imagine at some point in history it must have made sense. Would especially love references if you have them.

(please do not try to explain to me why you think HEAD is a good name today, I'm only interested in learning the history)

(1/?)

isntitvacant,
@isntitvacant@hachyderm.io avatar

@b0rk I am tempted to make the link between HEAD and the functional definition of a linked list (“head | tail…” or “head | rest…”); I’ll look to see if there’s any evidence for this association in git’s git history today.

isntitvacant,
@isntitvacant@hachyderm.io avatar

@b0rk Ah, yeah – I suspect that those were written later, by a different author, so there may be some delta from "what was the intent behind the name when chosen"?

The earliest commits I can find – 853916ff7f, 6ad6d3d36c, 16d4d1ba6c, and 8ba0bbb237 seem to treat "HEAD" as an ALLCAPS-style bash variable.

Looking through the bitkeeper source, which git was written to replace 1, there are at least a few references to "HEAD" around as early as 1999.

I’ve started to connect the dots that Smalltalk – and its object-oriented “language virtual machine” paradigm – emerged from the same primordial goop as the UNIX process model at around the same time, to solve the same problems: to create a standardized “extended machine” target for programs.
