Please know your philosophical razors if you dont already!

(taken from wikipedia):

Occam’s razor: Simpler explanations are more likely to be correct; avoid unnecessary or improbable assumptions.

Hanlon’s razor: Never attribute to malice that which can be adequately explained by stupidity.

Hitchens’s razor: “What can be asserted without evidence can be dismissed without evidence.”

Hume’s guillotine: What ought to be cannot be deduced from what is. “If the cause, assigned for any effect, be not sufficient to produce it, we must either reject that cause, or add to it such qualities as will give it a just proportion to the effect.”

Newton’s flaming laser sword: If something cannot be settled by experiment or observation, then it is not worthy of debate.

Sagan standard: Extraordinary claims require extraordinary evidence.

Popper’s falsifiability principle: For a theory to be considered scientific, it must be falsifiable.

Grice’s razor: As a principle of parsimony[disambiguation needed], conversational implications are to be preferred over semantic context for linguistic explanations.

Early rough draft, haven't proof read it yet. But just wanted to share the math behind creating an efficient Exponential Moving Average with a finite length/cut off. I found this was needed for a project I am working on where the EMA much be determined by random access to various points in a time series and couldn't be calculated for the entire time series in one go.

I needed to modify the EMA for a finite back-length. The standard EMA is only really efficient when calculated sequentially for the entire time series. This implementation is an efficient design that allows for calculation at a point by using finite back-length.

This is an early draft, did not proof read it yet, just whipped it together, though pretty sure the math is close to the final form. I will publish it sometime tomorrow but want to share what I have and welcome and questions or feedback before I publish it.

Here is known the one and only Plume(最新6DEV!) with open-registeration, thanks!


Hello, today I may not want to see unlisted posts in the Group timeline. In addition, I wish it would be nice to have a choice by non-default option like screenshot location. But many thanks always! 👁️

@hallo I’m testing of MathJax3\(\LaTeX\) MarkDownLink

and so on

For this weeks #FollowFriday I am going to do a groups addition.

@Electronics - An Electronics Group
@theamazingweb - A group about interesting and novel things on the internet.
@vim - A group for everything VIM
@funny - A group for humour and memes
@mnmlsm - A group devoted to discussing unix and related topics
@calligraphy - A group devoted to sharing and discussing calligraphy & handwriting
@FreeSoftware - A group for discussing Free and Open-source software
@math - Everything math!
@dogs - A group for sharing pictures of dogs, for any reason.
@Science - A group to discuss Science topics.
@photography - A group for sharing or discussing photograph.

So its been about a month since the QOTO Moderated Groups Server came online at It adds group capability to the fediverse with an owner capable of moderating membership in the group unlike previous group servers which were completely unmoderated and open.

We have had some amazing groups form and overall the server seems to be the most popular on the fediverse, I’m seeing more activity than the open-group servers which is great!

As such I wanted to share a list of a few groups I know of so far in case anyone is looking for a group to follow. Just follow the group as you would a user and you will be in the group and receive group posts in your timeline!
