Environmental awareness

Thu, 06 Feb 2025 21:27:27 +0800

I generally don’t really care about things that are not immediately affecting me, including my living environment outside of my room and bathroom, people that I talk to less than once per day, items that I use less than once a week.

This means I forget things so fast that I generally don’t remember details about a person (or their existence) after half a year or so, it is kind of sad that I operate this way. Sometimes I don’t even remember what I did in the morning, because it seems to me that being aware of past actions is not important if you don’t share it with others. (or maybe do statistical analysis/planning, but you don’t even need to remember with your brain, external storage is good enough.)

Working harder?

Wed, 05 Feb 2025 21:54:20 +0800

With AI coming, I should probably work harder to get money fast? Anyways today I looked through Macau job statistics and a video on US job market. Also going through https://swcarpentry.github.io/shell-novice and basically finished it.

ManicTime is very useful lol, to write about what I did today I am using it with its screenshot per minute function.

Working long hours is honestly pretty tiring, I hope I don’t have to do 8 hours every day in the future.

I currently can only put in around 6 hours of serious effort on something per day 🤷‍♂️

Python dataclass with readonly attributes

Thu, 09 Jan 2025 14:44:22 +0800

(I wrote this: https://stackoverflow.com/a/79341515/20891286)
Python 3.10+

Uses Wizard.Ritvik’s answer and modified it so that the API is closer to normal dataclass, and supports all the parameters of field()

The signature_from function is just a utility for static type checkers and can be omitted.

Note that PyCharm, as of time of writing, has quite a few static type checking bugs and thus you may need to turn off “Incorrect call arguments” or it will complain about unfilled parameters in frozen_field()

from dataclasses import dataclass, field, fields
from typing import Callable, Generic, TypeVar, ParamSpec, Any


T = TypeVar("T")
P = ParamSpec("P")


class FrozenField(Generic[T]):
    """A descriptor that makes an attribute immutable after it has been set."""

    __slots__ = ("private_name",)

    def __init__(self, name: str) -> None:
        self.private_name = "_" + name

    def __get__(self, instance: object | None, owner: type[object] | None = None) -> T:
        value = getattr(instance, self.private_name)
        return value

    def __set__(self, instance: object, value: T) -> None:
        if hasattr(instance, self.private_name):
            msg = f"Attribute `{self.private_name[1:]}` is immutable!"
            raise TypeError(msg) from None

        setattr(instance, self.private_name, value)

Nextcloud

Sat, 21 Dec 2024 13:00:17 +0800

Just managed to get nextcloud running after like 5 hours of messing around. Because my VPS only has 40GB I had to buy a new volume, point all of docker to the new volume.

All the weird discussions/tutorials online doesn’t really work for me:

In the end I used the official compose.yml file (permalink) and adapted a bit, then it just works. I guess most of the info are outdated.

Kilburn II turns off itself after 10 minutes of inactivity, even while charging

Fri, 20 Dec 2024 17:39:35 +0800

https://www.marshall.com/us/en/support/speakers/support-for-kilburn-ii/how-to-use-the-standby-mode

If the Kilburn II is left unused for 10 minutes, the speaker saves battery charge by going into standby mode.

In this mode, all indicators are off, and the speaker does not respond to Bluetooth connections. You can charge the battery as usual while in standby.

Push the Bluetooth button to wake the speaker from standby mode.

There is no way to disable this mode, as it is required for the safety and longevity of the battery.

Funeral is a social event. Dead people are dead. We pretend like it is for the dead person but it is just grieving. Forcing people that don’t care to go is stupid.

Recently (last 2 days) been having youtube addition, and this show is one of the big time sinks. Watching people do tasks that are intentionally crafted to be strange, difficult and containing loopholes in the rules is so fun.

https://www.youtube.com/watch?v=MQzQuSk8VqI is one of my favourite compilation.
