Hello world again, long time no rant.
Renewed interest in devRant after some of recent goings on:.
“Let’s define a new language”
“Why? There are lots of great languages out there”
“It will be domain specific and more user friendly”
“Why, there are plenty of other options with support and pedigree”
“We will properly define a grammar in Backus-Naur form, it’ll be great, maybe we can sub it out”
“Why, literally everything we do is already doable with the current tools, this will certainly be more trouble than it’s worth”
“They already gave us the money”
All aboard! Fun times ahead for the next decade...8 -
This is meant as a follow-up on my story about how I'm no longer and Ada developer and everything leading up to that. The tldr is that despite over a decade of FOSS work, code that could regularly outperform a leading Ada vendor, and much needed educational media, I was rejected from a job at that vendor, as well as a testing company centered around Ada, as well as regularly met with hostility from the community.
The past few months I have been working on a "pattern combinator" engine for text parsing, that works in C#, VB, and F#. I won't explain it here, but the performance is wonderful and there's substantial advantages.
From there, I've started a small project to write a domain specific language for easily defining grammars and parsing it using this engine.
Microsoft's VisualStudio team has reached out and offered help and advice for implementing the extensions and other integrations I want.
That Ada vendor regularly copied things I had worked on, "introducing" seven things after I had originally been working on them.
In the almost as long experience with .NET I've rarely encountered hostility, and the closest thing to a problem I've had has been a few, resolved, misunderstandings.
Microsoft is a pretty damn good company. And it's great to actually be welcomed/included.2 -
Proudest bug squash? Probably the time I fixed a few bugs by accident when I was just trying to clean up an ex-coworker's messy code.
So I used to work with a guy who was not a very good programmer. It's hard to explain exactly why other than to say that he never really grew out of the college mindset. He never really learned the importance of critical thinking and problem-solving. He did everything "by the book" to a point where if he ran into an issue that had no textbook solution, he would spin his wheels for weeks while constantly lying to us about his progress until one of us would finally notice and take the problem off his plate. His code was technically functional, but still very bad.
Quick Background: Our team is responsible for deploying and maintaining cloud resources in AWS and Azure. We do this with Terraform, a domain-specific language that lets us define all our infrastructure as code and automate everything.
After he left, I took on the work to modify some of the Terraform code he'd written. In the process, I discovered what I like to call "The Übervariable", a map of at least 80 items, many of them completely unrelated to each other, which were all referenced exactly once in his code and never modified. Basically it was a dynamic collection variable holding 80+ constants. Some of these constants were only used in mathematical expressions with multiple other constants from the same data structure, resulting in a new value that would also be a constant. Some of the constants were identical values that could never possibly differ, but were still stored as separate values in the map.
After I made the modification I was supposed to make, I decided I was so bothered by his shitty code that I would spend some extra time fixing and optimizing it. The end result: one week of work, 800 lines of code deleted, 30 lines added, and a massive increase in efficiency. I deleted the Übervariable and hardcoded most of the values it contained since there was no possible reason for any of them to change in the future. In the process, I accidentally fixed three bugs that had been printing ominous-sounding warnings to the console whenever the code was run.
I have a lot of stories about this guy. I should post some more of them eventually.2 -
Finally developed the domain-specific language for random text generation I've been brainstorming for years. It's a pile of steaming shit, but it's MY pile of steaming shit.3

!rant / Joke
RoR dev (Me): Damn, I gotta learn more about that routing DSL... Shit's powerful.
Networker: That sentence made zero sense... Did you just use technobabble? Go to marketing you dweeb.
Well, Matz really trolled the networkers there...
Ruby/Rails:
DSL(Ruby) = Domain Specific Language.
Routing (Rails) = Defining URL Patterns and assigning them to controllers.
Networks(As far as I understand, I only know the absolute basics there):
DSL = Digital Subscriber Line
Routing = The act of passing a packet through another network
"Oh, you can't help that," said the Cat: "WE'RE ALL MAD HERE. I'm mad. You're mad."
And the weird penguin building a rails app is mad too I guess.1 -
Following from https://devrant.com/rants/1516205/...
My emacs journey day 0-1
0: quickly realised what I was getting myself into, wow that is a learning curve. Head is buzzing with different key commands (and thank you to everyone who's helped out in my original post). I've been here before with Vim, but it's so hard when I am proficient with another editor, one of the most difficult aspects is getting it set up to even format my code appropriately (the right tab width etc), but I press on, something tells me it will be worth it in the end.
1: I come across a tutorial for clojure and emacs (https://braveclojure.com/basic-emac...), this looks good, oh sweet it shows how to load a good configuration, some more useful commands, feels like I'm getting there. Then it hits me, I manage to put my finger on why I decided to take the plunge: emacs isn't an editor at heart, at its heart is lisp. From its core it is scripted using one of the most powerful types of languages. Rather than some bolted on domain specific scripting language.
Now the real learning begins.2 -
I'm hurtling down the Dunning Kruger slope in Rust datastructure design. The orchidlang crate has a struct that attempts to wrap and replicate a slice for no reason other than to attach some domain-specific methods and a custom Display implementation. I came up with 4 different representations for a file URI as provided by the language client. The most recent one holds a singular string in an Arc. I know that these are bad ideas but I don't know why I keep coming up with them.6

We need a domain specific language for AI that is tailored for big data. So many tools are just not scalable to the size needed for these massive AI problems. It needs to be able to conceptualize and handle the fattest data in the industry.
We should call the language: Your Mom2 -
I have to make a domain-specific language for one of my classes (we will be working on it for the next two semesters) but I can't think of anything to do, do you guys have any ideas?5

Heres a truly vitrolic and unnecessary rant:
Package control for sublime is all well and good
through the command palette, but it's just
fucking retarded. How about you point me to a
FUCKING COMMAND to actually INSTALL A
MOTHERFUCKING PACKAGE YOU
FINGERPAINTING FUCKWITS?
Under babel plugin while browsing packages
on packagecontrol.io:
"Find it as Babel through Package Control."
FUCKING HOW?
What command?
What fucking command? How do I "Find" it?
The browse command just opens my
motherfucking browser. How do I fucking install
your fucking packages you assholes?
"Use autocomplete" except your god damn
autocomplete doesn't list "install package"
for some god damn reason because everything
web is a broken pile of utter shit, built
on a more shit, like a leaning garbage tower
of bullshit waiting for the smallest mistake to
take down the entire house of cards like
someone removing a leftpad on npm.
Maybe specify I have to enter
"install package" and THEN hit enter, and THEN
enter the GOD DAMN MOTHERFUCKING package name
on a separate god damn line for
some fucky reason.
Next time don't make a tool that breaks
motherfucking conventions. It's bad enough
every fucking look-at-me-im-smart cunt of a
dev and their dog has to invent a CLI and
then go and invent a new domain specific
language too motherfuckers.
Next tool that breaks convention around me is
gonna see the dev lit on fire.
fucking uppity cunts.
"Say thanks" the site say. I am not
feeling fucking thankful at the moment.
The least you can do if you're going to
contribute to open source, is not make things
actively fucking worse, least of all in the
fucking *documentation*.
FUCK count for this rant: 19 / 50,
RANK: RUSH HOUR TRAFFIC
0-5: GENTLE AS A LAMB
6-10: ANGRY GOAT
11-15: NUN WITH PMS
16-20: RUSH HOUR TRAFFIC
21-25: CANTANKEROUS VIETNAM VET
26-30: BREAKING SHIT
31-35: DOMESTIC DISTURBANCE
36-40: BIPOLAR EPISODE
41-45: DESPAIR EVENT HORIZON
46-50: BROKEN CAPSLOCK
50+ : MIDLIFE CRISIS / MASTER GRAND WIZARD
OF RANTS AND ANGRY-WORD MASTURBATION.
If you prefer to cheat, you may also include any
cursewords in general, but be warned, you'll
never know the sweet taste of victory when you
achieve the rank of master grand wizard.
Like when you were a kid, and you discovered
gameshark, and all your hopes of finishing that
one game became but a ruthlessly hollowed out
husk, somewhere where could-have-been childhood
memories and nostalgia go to die like the
graveyard of dreams
(the same place officer workers souls go).4
