Some notes on my language:

  1. I do use jargon to aid with clarity & concision. In my blogposts I make an effort to add links to any jargon I write, & feel free to ask for definitions. Also, jargon helps me gloss over all the parsers I see in my studies.

  2. When I use the term "edgecase" that's me asking the question "How do I handle it when these 2 things meet?" If you use the term to discard potential users, shame on you!

I'll see how many more of Shadow's authorization/accounts commandline tools I can cover this morning...

After initializing internationalization, some vars & SysConf id validates the count of commandline args (possibly ouputting usage), retrieves the process's user & group IDs followed by the corresponding password/group entries outputting them if non-NULL, possibly iterates over the user's groups looking up & outputting each of them, & cleans up.

1/?

After initializing LibShadow & validating at least 2 commandline args are given newuidmap looks up the PID for the first argument, opens its /proc/ directory, finds the user's password entry, performs validations, parses remaining commandline args as ranges, validates each of those ranges, & outputs them to the proc dir's uid_map file.

newgidmap works very similarly!

Unless the command's disabled, after initializing LibShadow & internationalization grpunconv has a special -R case.

2/?

@alcinnz@floss.social avatar

Then it parses the remaining -h commandline flag, checks that /etc/gshadow is present & can be opened under a lock, & linear-scans that file to find the entry to overwrite setting the password.

After init'ing i18n logout might fork if the debug flag is set, initializes logging & LibShadow, & repeatedly iterates over the utmp[x] file checking if they're allowed to be logged in at this time. If not it forks, sends a message to their terminal, killing their process, & syslogging.

3/3 today!

How To Survive Your Project's First 100,000 Lines - Evan Ovadia: https://verdagon.dev/blog/first-100k-lines

100k LoC is where I start getting really concerned about software complexity. But Ovadia's writing a compiler, which is well suited to taking complexity off other projects!

As for my browserdev strategies: I lean heavily on Haskell's typesystem more than I use assertions. Unexpected codepaths get debugging statements.

Haskell's designed specifically to avoid non-determinism!

I have unittests (could have more), which I find valuable to help me build the individual pieces. But end-to-end are the more exciting, where I have webpages I want to test against!

I have clear module boundaries which helps both me, & others reusing my code.

Ovadia advises prioritizing dev velocity, & isn't keen on Haskell's inflexibility. Personally I find Haskell very expressive & it's errors helpful. It has good compiletimes (not great) & memory safety.

Rad things about mastodon we take for granted

CW - these are amazing

Editing posts - hard to go back once you taste this

Alt text as the norm - total community enforcement

Replies - option to delist them so we don’t clog the feed

Timeline curating - we have near infinite timeline options with filters, lists, local, federated, hashtags etc

Muting - we can choose a time period!

Character count - 500 let’s you get an effing thought out

Ownership - we can own the damn thing ourselves

@yatil @notjustbikes @EposVox @seachanger My tip specifically for your images: Naming the location as the description should be enough. That fits the purpose of your images!

Proofreading my code for inserting extra text into the styletree, I've found a few corrections to make already!

  • Corrected from display: list to display: list-item to trigger generation of "list markers".
  • Added implicit counter-increment: list-item to that display type.
  • Added support for list-style-position: outside; marker-side: match-self/parent;. Involved parsing direction property.

Few more fixes, which should really help my auditory browser "Rhapsode":

  • Found a bug where counters weren't getting inherited unless they were being modified. This fix should really help Rhapsode's in-page navigation!
  • I now pay attention to @counter's speak-as property. If caller supports the more general property.

Finally, I've made a tweak to ensure newline-collapse settings are preserved during whitespace collapsing!

Tomorrow I think I'll publishing this new release of Haskell CSS Syntax!

The most important projects I think right now for the software freedom movement & the open web are art! As long as it's published DRM-free!

It doesn't even have to be about our movement (though do please advocate something positive).

If you use free software that helps us improve & advertise "look what can be accomplished!" But regardless just having something DRM-free helps avoid the bad look of endorsing piracy.

    @khm Good to have this clarity, the top-of-thread could be interpreted as overly toxic!

    As someone who semi-regularly uses Firefox (behind GNOME Web or my own not-ready-yet handiwork; ie not Chrome) I would say there are things to complain about regarding Mozilla & Firefox. I find much of their behaviour quite tragic & self-sabotaging.

    But FakeSpot isn't one, at least yet, & I prefer to focus on "What are we doing about it?"

    alcinnz,
    @alcinnz@floss.social avatar

    @khm Fully agreed!

    The "it doesn't support all the same web standards Chrome does" complaints bothers me a lot as an amateur browserdev. I can't compete on that metric at all, while others struggle!

    It is bad business to start your own protocol when there's an existing open standard.

    It's like making a new brand of air.

    Open standards are a commons. They're a gift. Some idealists and eggheads have already worked out the hard parts. You get that part of the stack 100% free.

    Why in the world would you put any effort whatsoever into replicating the free part?

    Work on the other parts. The parts people care about and pay for.

    alcinnz,
    @alcinnz@floss.social avatar

    @evan I'd never say don't work on new standards, but I would prefer if I saw new standards be better justified than I usually see.

    Work subtoot: "Developers prefer JSON" is not a satisfactory justification in my books!

    alcinnz,
    @alcinnz@floss.social avatar

    @Andres @evan How about "never work on private standards"?

    You have no right to refer to it as a standard if you don't seek external input & implementations!
