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.

@Pat Its great to have you here, Im the founder here on QOTO, look forward to seeing your posts and getting to know you. Feel free to reach out anytime.

@jojo It can be, you just need to know who is worth your time.

@nygal It is unlikely that is due to that being anywhere near the actual number in 2020. typically you dont get the complete numbers for a year, when compiled by most agencies, until sometime after the year is complete. Most sources are going to report partial figures that arent useful.

Its the same thing with the nonsense you hear about the death count going down in 2020, which isnt true. You just need to use different sources for historic data than you do real-time data and is very common with data sets.

@nergal

four sides, you and me are the 4th...

five sides, we are actually just characters in a meme and the people watching us are the fifth side.

@Gargron

Awesome to hear that, I have seen some pretty slow queue times on account deletes through suspending in the past. This will be good to see, thanks.

To be fair the only way guppe would boost a post that is private is if you explicitly tag it (in which case you are asking it to boost it). It also wont boost the whole thread, only the specific message that tagged guppe asking to be boosted.

With that said, I do understand those concerns and as will said it was an experimental project with limited features. As he points out the https://groups.qoto.org project does, indeed, address all those concerns. It is based off the mastodon code base and as such honors privacy to the same extent and in the same ways the base mastodon project does. It is just modified to make "users" into "group agents" instead.

@jasper sorry for all those typos, was just waking up and on my phone when I replied.

@hansw to me the big red flag is that he is changing names to circumvent your ability to ignore him... that would cause me to instablock anyone in any scenario really.

@valleyforge Hell and lets not even get into the fact that the warrant was obtained illegally with police officers lying (later revealed in public statements) in an attempt to obtain the illegal warrant.

They obtained the warrant by claiming they worked with the post master general and there was evidence of illicit packages being sent to her home which a drug dealer allegedly then picked up.

The warrant states that this event was verified "through a US Postal Inspector"

yet...

In May 2020, the U.S. postal inspector in Louisville publicly announced that the collaboration with law enforcement had never actually occurred. The postal office said it was actually asked by a different agency to monitor packages going to Taylor's apartment, but after doing so, it concluded, "There's [sic] no packages of interest going there."

@valleyforge No thats a high dishonest accounting.. Police officers in plain closed knocked down a door with eye witnesses claiming they did not hear them announce themselves as police and even if they did they were not showing badges or any identification as police.

Boyfriend defended his home against supposided intruders by shooting a waning shot which was entirely within his right, and only lightly wounded one of the plain clothed individuals in the leg (as was the intent of a warning shot). Officers then returned a volley of at least 32 shots intending to completely kill anyone and everyone int he vicinity (and putting neighbors at risk due to cross fire). all 32 shots missed their intended target and, as expected killed Breone, an innocent bystander.

To add insult to injury the reason for them breaking into the home, the search for drugs, never revealed any drugs of any kind.

A very different picture than the one you describe.

@trinsec

wooden ones, and yea, very much the norm among my friends and the area I'm in.. keep in mind my friends are native dutch and they all agreed that clogs were still used for gardening among the older generation. It coudl be regional though I dunno.

@mur2501 @LoStz

@trinsec

In the area I live (outside of utrecht in the country area) it is quite common, my neighbor wore them all the time and all my friends who have parents with gardens told me they all used them as gardening shoes.

@mur2501 @LoStz

@trinsec

Well to be fair most of those are accurate, at least to a point. You have windmills everywhere, people still wear clogs when gardening, you grow more tulips than weed, and there is raw hering within walking distance of anywhere yo ucould hope to be :)

@mur2501 @LoStz

@trinsec

:) very typical
