@NathanOsman I just wasted a whole day trying to implement my comment system, but at least I made some progress.. Jekyll Liquid doesn't help when it comes to flow control and logic, I needed to use recursion and was banging head to find how, then realized it's not possible (at least not without a hack I couldn't even imagine). So I decided to make a script that wrote a Liquid template with a limited number of recursion interactions.

That Liquid template transforms all the comments in a JSON tree that I fetch with AJAX to fill the comment section. Still a lot of work to do, but I managed to compartmentalize staticman, so I only give the app collaborator priviledges on the repository that holds the comments. I think once I'm done I'll write about how I did it, would make a nice (probably long) post

iancaio.github.io/blog/front-end/2018/01/13/…

still a lot of work to do, and also needs some better styling, specially in the form

By the way, the comments are still moderated. I didn't make it script-safe, so I have to approve any comments before they are merged to the comments "database"

TheWanderer

why does git rm remove a file from disk?? -_-

IanC

@TheWanderer didn't get it, isn't that the point of rm? :p

TheWanderer

git rm?

IanC

removing a file from the git repository, you mean it removes from outsite a git repo?

TheWanderer

I did git rm on a local file and it deleted the file itself

--cached doesn't delete the file

@TheWanderer That's the main point of git rm: to delete the file both locally (if it's there) and from the index at the same time.

@ChaiT.Rex it could check if the folder is a repo though :p

Chai T. Rex

@IanC Ahh, I didn't know it did that.

IanC

@ChaiT.Rex sorry, I meant "it could" as in "it should" check, but apparently it doesn't from what @TheWanderer said

I never tested it outside a git repo

TheWanderer

12:39 AM

no this was a repo

but twas me blindly copying commands

Chai T. Rex

@IanC I just did touch whatsit; git rm whatsit and it doesn't delete non-git files.

IanC

oh, it did as expected

yeah, just tested here too

but I'm confused, what you thought weird about git rm @TheWanderer?

TheWanderer

well

I looked up how to remove a file from git

that was the result

IanC

I honestly don't know the difference between using git rm and regular rm though

maybe git rm protects you from removing files from .git or listed on .gitignore?

TheWanderer

well git rm will remove the file in git too :p

rm won't remove anything from .git or .gitignore

IanC

12:50 AM

@TheWanderer it does, if you write rm -rf .git or rm file-from-gitignore

but I think I know the difference now

TheWanderer

oh wait I get what you mean

IanC

if you have a file on .gitignore, you can't delete it with git rm, because it's not in the project tree

TheWanderer

I thought you meant physically remove a line from .gitignore lol

IanC

regarding regular files, git rm file seems like the same as rm file; git add file

it removes and adds the "Delete" to the HEAD for the next commit

Can't wait for the Python 3.x => 4.x transition :P

Should take a few years or so.

Hey, wasn't there supposed to be a static fire test for the Falcon Heavy today?

> "An attempt at 1 PM EST today, January 16, was canceled for unspecified reasons, although Kennedy Space Center reportedly maintained the usual roadblock to prevent vehicles from driving past, implying that SpaceX still intends to conduct propellant loading tests with Falcon Heavy."

Aw darn.

IanC

rocket launch?

Nathan Osman

No, not a launch.

It's a static fire test, where they run the engines at full throttle but the engine is clamped to the ground.

IanC

that sounds almost as cool as a launch

Nathan Osman

Oh, it is cool.

But it has been delayed for unspecified reasons.

This is the world's most powerful rocket.

So I'll cut them some slack :P

IanC

they'll broadcast it on youtube?

Nathan Osman

Oh I'm sure they will.

New executable in #systemd: jsond. All data structures must now be passed to jsond for proper encoding and the results can be retrieved from jsond using its embedded HTTP server. Note: do not pass data structures that start with a number or undefined behavior may result.
