went to sesc paulista. last time i visited was years ago, soon after it first opened. the top floor now seems to be accessible only through reservations now.

this was the first time i tried connecting to wifi with this new arch installation.

the cachyos distro came with nmcli. i am not yet certain that it is a common dependency for other distros.

this lists the available wifi networks:

nmcli device wifi list

this connects to wifi:

nmcli device wifi connect connection_name password connection_password

took me a while, but i managed to figure out how to show a preview of a post instead of the whole post.

last year, masp's new annex opened to the public. i had the opportunity to visit at opening week. a few weeks before that, i bought a tiny thermal camera that prints on receipt paper.

while using pandoc on arch, i got an error as i tried to convert a markdown to a pdf.

conversion snippet:

pandoc document.md -o document.pdf

microsoft's documentation for between doesn't mention inclusivity at all until section b, which suggests that between is inclusive. the information is only really explicitly stated all the way down in section d, where it states that (for datetime values, at least), between is inclusive.

however, as i have come to find out (not before a whole hour of debugging): it ... depends?

i tried using the auto builder, but either i did something wrong, or there is a bug with it. nikola depends on the python package watchdog for the continuous auto-build. i might try it again some other time.

looking at the commit history for the repository containing the source for this blog, you may notice that this was originally my personal website/cv.

my initial intention was to setup the present blog on a separate branch, but i forgot to switch branches before deleting everything.

in any case, i suppose i'll have to commit to this now. so here is a test post.

checking if a task has failed on airflow is simple enough, and may be done with:

from airflow.operators.python import get_current_context

@task
def check_task_failed(task_id: str) -> bool:
      context = get_current_context()
      return (
          context["dag_run"]
            .get_task_instance(task_id=task_id)
            .state == State.FAILED
      )
