I really want to code more open-source Haskell but i just cant justify the lack in contribution that would result in....

#haskell #it #cs #programming

This multibimap was a really fun algorithm to implement in Haskell:

https://anaconda.org/freemo/multibimap/notebook

#Haskell #programming #CS

So Gremlin Python ( Tinkerpop 3 ) does not have transaction support. So only way to get transaction like behavior is to make sure you do everything in a single database traversal.

Because I am writing an ORM / OGM model as my base that means I needed to implement something that looks like optimistic locking all my own (only works on immutable write-only graphs). Its a huge pain in the ass.

Anyway after half a day I finally figured out this is the traversal I need to resolve my optimistic lock when creating a single new node in the DB:

session.g.E().has('dirty',1).aggregate('x').fold().V().has('dirty',1).aggregate('x').choose(__.V().hasLabel('account').has("fingerprint", "DEADF00D").hasNot('dirty').count().is_(0), __.select('x').unfold().properties('dirty').drop()).iterate()

Good morning everyone. I went to bed last night with a breakthrough. Finally got python's Goblin module working on the Janus GraphDB just moments before bed.

I'm super excited because that means the full tech stack is in place. full docker-compose environment, full integration tests. Everything I need for a perfect environment to start developing this project for real now!

Anyone around here any good with #c or #c++ ? I have an issue I cant resolve...

For todays #FollowFriday I'm going to do something a bit different. We have a lot of new users, one of the biggest surges we have seen in a while. As such a lot of new users are looking for high quality, long-standing, accounts to follow. Similarly many of the new users need some help getting attention and making new friends.

As such I am going to do this #FF in a few parts. One for old users I have mentioned in previous posts, as well as some of the new users who have been making quality posts and been active for at least a week now. Hopefully this will be more helpful.

Also a section for some bots might be useful.

I will use a persons profile description here as I dont want to misrepresent anyone.

So I'm trying to consider what framework to use for documentation at CleverThis (first document ill need to convert is the Spec for the concurrency I'm designing). These are the options I'm playing with and considering. Which do you like most, leave comments with suggestions and opinions.

This was a really fun programming challenge originally proposed by @Absinthe I want to paste it here, along with my solution, so everyone who is interested can check it out.

Here is the link to his original post: https://qoto.org/@Absinthe/102895801091007015

#toyprogrammingchallenge
Another Freebie...

This problem was asked by Facebook.

Given the mapping a = 1, b = 2, ... z = 26, and an encoded message, count the number of ways it can be decoded.

For example, the message '111' would give 3, since it could be decoded as 'aaa', 'ka', and 'ak'.

You can assume that the messages are decodable. For example, '001' is not allowed.

Here is the link to my solution: https://qoto.org/@freemo/102898629821739556

My solution. This should be a somewhat space-optimized solution in ruby based off the modified concept of a Trie.

https://git.qoto.org/snippets/4

If i made this into a Radix Trie by compressing nodes with single children down I could reduce this further.

But since it does work I thought I'd share it as is. I'll update everyone if i decide to finish optimizing this particular solution.

It does however do a fairly decent job at compressing the tree by making sure no subtree is a duplicate of any other part of the tree (a node of any specific length/id will be the only node with that length.

For clarity I attached a picture from my notes of what the Trie would look like for the encoded string "12345" where the value inside each circle/node is the "length" value of that node, and the value attached to an arrow/vector/edge is the "chunk" associated with that link. The end result is any path from the minimum node (0) to the maximum node (5). This diagram does not include incomplete paths which my program does right now.

Incomplete paths can also be trimmed to further reduce the space. But since incomplete paths each add only a single leaf node to the tree, and might be useful for various use cases I decided to keep it.

In case anyone is interested here is a link to a very difficult logic puzzle that anyone without math skills can solve (it is easy to understand though). I also include the answer with a CW for those who want to skip right to the answer.

The #QOTO Discourse server now has support for rendering Latex style psuedocode in posts.

Check out this post I just made explaining an algorithm I invented some years back. It includes the java code, psuedocode, and full text explanation.

I will do a seperate post soon explaining how to use the psuedocode in posts.

So far on #QOTO we have brought the following services up, I want to know what you want to see next. All of these services are free and open to the public for open-source and collaborative non-commercial ventures.

Here is what we have up so far:

Modified #mastodon server - https://qoto.org

#NextCloud server - https://cloud.qoto.org

GitLab server - https://git.qoto.org

Servers we intend to bring up:

#Pixelfed

#FunkWhale

#PeerTube

#Discourse

#Halcyon

Let me know which of the above you'd like to see next. Also if you have a suggestion of a service we didnt list let me know and we might just host it for you if it would be useful for others.

#QOTO We now have two more Federated services up on Qoto. They are still in beta so use at your own risk.

NextCloud: https://cloud.qoto.org
Gitlab: https://git.qoto.org

Feel free to sign up for an account and use the services. Let me know if you have any trouble using it.

Big things happening at #QOTO I wanted to update everyone on.

So as most of you know I had a year long back injury that put a lot of QOTO plans on hold. But I've been healed and working on bringing much of that vision to reality.

As of a few weeks ago a few close friends and fellow engineers wanted to join the team. I am currently sitting with 3 other new engineers and we are working on bringing up several instances including peertube, nextcloud, gitlab, discourse, and of course a newer version of QOTO. A full collaboration suite for others in STEM and the open-source community. All for free to its users.

This launch will coincide with several of my other projects many of you follow including protowaffle, ROES, Graphactor, Aparapi, Ferma and many others. We will host all the source on QOTO as well as make it the source for future software announcements related to those products.

Stay tuned for me.

Just finished revamping the coloring system and the descriptions of rooms displayed when you enter a new room or look around in Aethyr

Screenshot attached.

Some general info:

The game is called Aethyr and it is open-source and written in Java

You can find the source code here: https://github.com/Syncleus/AetherMUD

I did a little prototyping on a new layout for my game's character info. Not nearly complete (doesnt show most of the stats yet) but thought I'd share anyway. It at least gives an idea as to the direction im heading in on visualizing some of this stuff with just ASCII.
