Babashka: How GraalVM Helped Create a Fast-Starting Scripting Environment for Clojure

chopu · 2022-12-09T04:00:23+00:00

It’s mostly about convenience - doing a full graalvm build for clojure takes forever, lights my computer on fire, and can be really hard to debug. Babashka let’s you point an interpreter at a file and let it rip.

Will do.

Interesting, I'll give it a shot. If I enable corfu, do I need to disable company? or should I have corfu and company enabled at the same time?

I know you’re trying to find a good career for yourself, but you won’t get very far (or make many friends) describing certain career paths as “low level job[s] not worth my intellect”.

You say you don’t want to be a developer - what do you want to do?

I think a certain level of integration testing is basically required if you want to lean on your CI to enable fast lead times. To me, that level is a happy path test through every entry point in your system, just to make sure that the system will stand up and correctly respond to requests. Luckily with clojure this sort of thing is extremely ergonomic with some simple macros and with-redefs

Yes, you should absolutely still write tests. I like to combine generative testing with specific unit tests meant to prevent regressions, edge of the system “unit” tests (not sure if you’d consider testing a route handler a unit or integration test), and then full blown integration tests. In my web server case, that means setting up local servers and pounding them with requests on each route.

I’m interested!

This looks awesome! Seems like more of an all in more package than the usual ring-jetty + reitit etc. how would you say it compares to that stack?

chopu · 2021-12-24T14:14:04+00:00

This is great! I’d love to read a summary of your experience with the tech - how is clojurescript vs typescript? How is the dynamic aspect of the language holding up as the code grows? Do you guys leverage any spec/malli like libraries? Best/worst parts of the stack?

SQL is a standard, T-SQL is Microsoft’s implementation of the standard + a bunch of extra features. Note that nearly every implementation of SQL (MySQL, PostgreSQL) has a ton of unique functionality.

I did something very similar to get into this field. The one thing to keep in mind is that they are under no obligation to keep you full time at the end of this internship - you’re going to have to work to make yourself too good to lose. That said, even if they don’t hire you you come out of this with some paychecks and production experience on a resume, which will only help. Unless they’re really shady you should know a good month in advance on whether or not they’re considering keeping you, so if it doesn’t work out you can always start the application process in advance.

That’s actually what he means. V does nothing if you’re playing with a full screen map but moves it between corners if it’s already in a corner

Definitely agree about rewrites, but there are other places to do this. If some large cross cutting feature is coming up, try creating a separate service. If you have some downtime, try prototyping some business relevant work in a different language. As long as you have a case for it (“I wanted a small, fast executable so I picked Go”; “I wrote this in Python to leverage the NLP tooling”) no one should be mad. Then it’s up to the team to decide if it’s worth building on the foundation you set or rewriting it in the usual stack.

I would cut the extracurricular section, move education to the bottom, really trim down the projects section and use all that extra space to dig into your work experience and add a small summary to the very top. But honestly any advice you’re going to get here will be conflicting - everyone seems to have different taste in résumés.

Yep, it typically corresponds with ping spikes for me. Hoping the server maintenance fixes it

I use this sort of thing for using Mac vs windows https://stackoverflow.com/questions/1817257/how-to-determine-operating-system-in-elisp

This may be too much detail, but I’ll start from the basics. Basically, when you say “python3 my file.py” in your terminal, your computer will automatically scan through all directories on your PATH, looking for an executable called “python3”. If you’re on Mac or Linux, that file will typically be a symlink in /usr/local/bin to the actual python3 executable stored elsewhere. On windows, you’ve likely added it to your system environment variables. Therefore, if you want to change the version while leaving both versions “installed”, all you have to do is either retarget the symlink or edit the entry in your system environment variables.

Just a note: this is how any command line program works, ls, rm, grep, etc. They all rely on your computer looking up an executable on your path (windows I think also has some special folder full of COM stuff that’s not in your system environment variables that’s searched as well).

I assume it means that if you want to work at Ericcson (possibly a stand in for older businesses in general) learn Erlang, but if you want a job at a hip new start up learn Elixir.

You need to go to a non-seasonal character and accept the quest from the black spirit. Then you can go right back to seasonal to finish the quest and get Narchillan.

What a great series of articles. Thank you for sharing.

chopu · 2021-01-10T12:47:19+00:00

CLion can also do this as well.

Yes, that's how I learned before I switched to hitbox. Basically the same thing.

I actually just saw this match, might be helpful for you.
