# how to disable ps4 dualshock controller sound on linux
when the controller is attached via cable, sound is routed to the controller headphone out by default.
to change that, attach the controller, open pavucontrol, find the output for the controller and disable it.
this setting should persist even if the controller is removed or the computer restarted.

# tool marketing invention insight
tools can be harder to sell than the things one can do with them. especially if one wants to do something with them that no one so far wants to do, so that existing tools are already sufficient to most. trying to sell the tools means trying to sell them on what you can do with them, but no one will care since they dont want to do what they can do different, it is not significant, and for what the mass already wants to do, existing tools are more reliable

mastering herp derps.
there are many types of herp derps. what are herp derps?
a herp derp can be very powerful.
it is often used in important tasks.
more and more people are needing it every day, as the busy life of society continues.
herp derp is so great, nobody can go without it.
and it is so easy to understand, it is so simple, it will be trivial really.
on this page, we will explain what it is.
dont be afraid, it is not that hard to understand. take a deep breath and let's get our feet wet and dip our toes into the topic to deep dive on what this article is about.
we will summarise all that it is, and give you the complete low-down on herp derp. so that at the end of this article, you will have mastered it.
summary of the following contents: what is a herp derp, and what you can do with it.
the name herp derp is constructed from the words "herp" and "derp".
which means the words "herp" and "derp" are combined to describe one thing. the words are written with letters used in the english language.
we are sure you will need herp derps frequently in your professional life, as it is that special.
herp derp, as herp derps usually are, are very important.
it is so strikingly useful, and so profound, that almost everybody should know what a herp derp is.
even your grandma probably needs a herp derp at least once in her life.
just like john derp herp, who in 1862 invented the first herp derp with his son, who had brown hair and was 152cm tall and made a joke in school that day and everyone laughed.
on a breezy summer morning you could have seen the excitement in his eyes, as john discovered the immeasurable significance of herp derp.
there are many different kinds of herp derps. it would be too much to explain everything in a single article.
some are more useful, some less so, but all are at least somewhat similar.
herp derp is simply a herp derp.
we hope that you now know everything you need to know about herp derp to truly excel at applying herp derp in your future endeavours.

# how to draw slopes with varying steepness
without specifying intermediate points in advance, with giving a value for rate to specify the steepness

~~~
(x, rate, previous_rate, previous_y, y_level)->
  x_rate = x * rate
  y_level =
    if previous_rate is rate
      y_level
    else
      x - x_rate + previous_y - (x - (x_rate - rate * (x - 1)))
  y = y_level + x_rate
  [y, y_level]
~~~

not obvious in this procedure, that can possibly be simplified, is how values have to be adjusted to keep the starting points of new steeper or shallower segments attached to the end of previous ones.
one can imagine lines of `f(x) = rate * x` with different `rate`. the lines cross only at zero and it looks a bit like a fan. with this function, one can get only points on separate slopes, with straight changes when starting to draw parts of different ones.
it is possible to translate the starting point of any possible slope by addition or subtraction to make it cross at exactly the point where `rate` changed and start drawing a segment from there.
in the above function, `x` and `rate` are the main parameters and the values used for correction are related to the center `y = x` slope and the end point of the previous segment.

but, this creates an ever growing number and there is potential for increasing numerical error with floating point numbers, either because the value becomes large and less exact or the input of previous_y and y_level accumulates errors through addition.

a probably better alternative would be a function that takes width and height instead of rate, to be able to calculate an endpoint, and then use an interpolation function to get points between the start and end points. if width or height changes, the target point would just move
