@mckinley@twtxt.net its hosted on the mini at home and ingress is handled through my MTR vm.
@mckinley@twtxt.net for me:
- a wall mount 6U rack which has:
- 1U patch panel
- 1U switch
- 2U UPS
- 1U server, intel atom 4G ram, debian (used to be main. now just has prometheus)
- 1U patch panel
- a mini ryzon 16 core 64G ram, fedora (new main)
- multiple docker services hosted.
- multiple docker services hosted.
- synology nas with 4 2TB drives
- turris omnia WRT router -> fiber uplink
network is a mix of wireguard, zerotier.
- wireguard to my external vms hosted in various global regions.
- this allows me ingress since my ISP has me behind CG-NAT
- this allows me ingress since my ISP has me behind CG-NAT
- zerotier is more for devices for transparent vpn into my network
i use ssh and remote desktop to get in and about. typically via zerotier vpn. I have one of my VMs with ssh on a backup port for break glass to get back into the network if needed.
everything has ipv6 though my ISP does not provide it. I have to tunnel it in from my VMs.
@bender@twtxt.net It is the new “politically correct”. Something that was used to describe acting in a more civilized way with one another. Turned into a scapegoat for the other side to label, demonize, and attack.
My email is such a cluster of noise. The only time i actually use it is to find out I have to do my security training or something. All communication is slack now days.
well @username@username rather…
yarnd does not do auto discovery via webfinger though.. i cant put @username and have it fetch the feed url from webfinger. to fully make feeds portable. would also need to be able to use that for hashing.
and then i have a compact version that makes things more grep’able in scripts.
You can’t catch the kill signal. Should this be syscall.SIGTERM instead of os.Kill, xuu? https://git.sour.is/sour-is/go-paste/src/branch/main/main.go#L21
You are totally right.. i think i was going for SIGTERM and SIGQUIT
I can query the configurations a few different ways. i can request the specific name foo.bar or a glob like foo.* or trace the hierarchy trace:some.deep.name.space which will give me the namespaces some, some.deep, some.deep.name, and some.deep.name.space. These can be combined.
@lyse@lyse.isobeef.org its a hierarchy key value format. I designed it for the network peering tools i use.. I can grant access to different parts of the tree to other users.. kinda like directory permissions. a basic example of the format is:
@namespace
# multi
# line
# comment
root :value
# example space comment
@namespace.name space-tag
# attribute comments
attribute attr-tag :value for attribute
# attribute with multiple
# lines of values
foo :bar
:bin
:baz
repeated :value1
repeated :value2
each @ starts the definition of a namespace kinda like [name] in ini format. It can have comments that show up before. then each attribute is key :value and can have their own # comment lines.
Values can be multi line.. and also repeated..
the namespaces and values can also have little meta data tags added to them.
the service can define webhooks/mqtt topics to be notified when the configs are updated. That way it can deploy the changes out when they are updated.
@mckinley@twtxt.net Don’t forget the syntax for arrays of sets [[foo.bars]] [[foo.bars]] [[foo.bars]]
@lyse@lyse.isobeef.org i made my own :D
I do prefer toml for the old school ini style with added support for object lists.
my second would be hjson or any other json with comments style.
how would that work with your encryption keys? you send them to a server that hopefully you control?
@movq@www.uninformativ.de Haha! yeah sounds about like my HS CS program. A math teacher taught visual basic and pascal. and over on the other end of the school we had “electronics” which was a room next to the auto body class where they had a bunch of random computer parts scavenged from the district decommissioned surplus storage.
The advanced class would piece together training kits for the basic class to put together.
@quark@ferengi.one pascal was high school for me 10th grade. I remember making an over the top Yahtzee game with text windows and everything. My instructor got mad at me because it was a ton of pages printed out to review.
I finished my data structures classes with C++ and the next year they changed it out with Java. When i transferred up after my assoc degree it was C++ using the counter-strike source game engine.
@movq@www.uninformativ.de before this century. Back when colleges taught C++ instead of Java for CS degrees.
@lyse@lyse.isobeef.org Yeah the func in func threw me off.. The generic type iter.Seq[V] does make things a bit more clear though.
Things can get very interesting when we add the iter.Pull function in the mix. It works like pythons yield from.
I would love to see a world where ones twtxt feed is defined by webfinger. So @xuu@txt.sour.is => https://text.sour.is/user/xuu/twtxt.txt
Then my identity can exist independent of the feed location. And I can host multiple protocol types for my feed. Ie. http/gopher/Gemini/irc DCC/etc
the function can yield two values to include an index.
The range function can signal when to stop running by returning false from the yield function.
Go 1.22.0 introduces a new experiment for range functions. Have you tried them out? What do you think it can make easier to accomplish?
@movq@www.uninformativ.de NASM is great. I remember playing with it back in my HS days. It has lots of little helps to make assembly more approachable.
anthony.buc.ci account. I am assuming these kind of bugs were never addressed by @prologic. :-(
@quark@ferengi.one @mckinley@twtxt.net
i think you have to be following the person so it does it correctly.
@movq@www.uninformativ.de its always fun to look back on old projects. I talked to an old coworker about a codebase i made back in 2010 that still has lots of the same architecture i built into it back then and is still in heavy use.
are these projects you created?
@eapl.me@eapl.me the 24th of June 2002 was a pivotal year in my life.
Found some additional context. This was filmed as a ‘skit’.. Though still not very safe as there is a slight lag from what is displayed on the visor I have heard. 
@movq@www.uninformativ.de the location is real. A few in the ‘hood mentioned seeing this person directly. They live somewhere on the hillside in the background of the video.
seen near my house..
@prologic@twtxt.net pretty nothing berger. The “blowout” was pretty tame coming from Linus kill yourself now. The world will be a better place” Torvold.
The issue was a dev making a “fix” that didn’t have a documented problem. They reused some specific low level functions they did not understand the reason they were made.
@prologic@twtxt.net ahhh! Its the dark reader plugin breaking the page.
@prologic@twtxt.net why am I getting this on your git? 
Twtxt spec enhancement proposal thread 🧵
Adding attributes to individual twts similar to adding feed attributes in the heading comments.
https://git.mills.io/yarnsocial/go-lextwt/pulls/17
The basic use case would be for multilingual feeds where there is a default language and some twts will be written a different language.
As seen in the wild: https://eapl.mx/twtxt.txt
The attributes are formatted as [key=value]
They can show up in the twt anywhere it is not enclosed by another element such as codeblock or part of a markdown link.
Not a fan of this one because the only context is machine readable.
@eapl.me@eapl.me: [boost]
Ha, this is cool. Has its flaws, although is easy to remember.

@sorenpeter@darch.dk this makes sense as a quote twt that references a direct URL. If we go back to how it developed on twitter originally it was RT @nick: original text because it contained the original text the twitter algorithm would boost that text into trending.
i like the format (#hash) @<nick url> > "Quoted text"\nThen a comment
as it preserves the human read able. and has the hash for linking to the yarn. The comment part could be optional for just boosting the twt.
The only issue i think i would have would be that that yarn could then become a mess of repeated quotes. Unless the client knows to interpret them as multiple users have reposted/boosted the thread.
The format is also how iphone does reactions to SMS messages with +number liked: original SMS
> ?
@eapl.me@eapl.me this is interesting. Is the square bracket something used in the wild for multilingual twts?
@prologic@twtxt.net what are your thoughts? Should we extend the parser to handle [lang] and [boost] ? Or a generic attribute spec. Single word is a boolean attribute. And one with an = is a string key/value.
@eapl.me@eapl.me kinda like the format for markdown images?  ?
What? You are still using chrome? Firefox is where its at. But if you need WebKit there is always chromium which strips out all the google nonsense.
When I built I had a blue conduit installed from outside in to the util room.
Laser all the way. Inkjets are cheaper to replace the printer than to buy the ink for a reason.
Are they doing fiber to outside with ether in? Or will it make it inside the house?
It would help for UX for sure. emoji keyboards are hard to come by on the desktop.
:waves:
@prologic@twtxt.net nope.
@prologic@twtxt.net what?
@lyse@lyse.isobeef.org I have read the white papers for MLS before. I have put a lot of thought on how to do it with salty/ratchet. Its a very good tech for ensuring multiple devices can be joined to an encrypted chat. But it is bloody complicated to implement.
@lyse@lyse.isobeef.org i first learned about it from this vid https://www.youtube.com/watch?v=6JxvKfSV9Ns&pp=ygUOZmlib25hY2NpIGhlYXA%3D
and this site: https://www.programiz.com/dsa/fibonacci-heap
So, I finally got day 17 to under a second on my machine. (in the test runner it takes 10)
I implemented a Fibonacci Heap to replace the priority queue to great success.
https://git.sour.is/xuu/advent-of-code/src/branch/main/search.go#L168-L268
@prologic@twtxt.net What I did as a work around for mattermost was hijack the gitlab oauth login with my own auth server.
OH MY FREAKING HECK. So.. I made my pather able to run as Dijkstra or A* if the interface includes a heuristic.. when i tried without the heuristic it finished faster :|
So now to figure out why its not working right.
i am wondering if maybe i need a better heap like a btree backed one instead of just list sort on Dequeue.
I found a bug where i didnt include an open/closed list that seemed to shave off a little. right now it runs in about 70 seconds on my machine.. it takes over the 300s limit when it runs on the testrunner on the same box.. docker must be restricting resources for it.
I might come back to it after i work through improving my code for day 23. Its similar but looking for the longest path instead of shortest.
man… day17 has been a struggle for me.. i have managed to implement A* but the solve still takes about 2 minutes for me.. not sure how some are able to get it under 10 seconds.
Solution: https://git.sour.is/xuu/advent-of-code/src/branch/main/day17/main.go
A* PathFind: https://git.sour.is/xuu/advent-of-code/src/branch/main/search.go
some seem to simplify the seen check to only be horizontal/vertical instead of each direction.. but it doesn’t give me the right answer
I have been doing interview prep for next year. The problems have been great to get practice and make it fun when compared to the dry solve this you get on hacker rank or code scene.
That and so many great write-ups to explain the problems.
@lyse@lyse.isobeef.org I think there is a problem related to the fitting around a corner that is unsolved. I watched a video about it a little while back.
I found these write-ups for advent of code. They are quite well done and a great learning resouce for algorithms!
My linux installs all have TPM enabled. …
@movq@www.uninformativ.de So.. i eventually made it to the end on this one.. was able to reuse code from days 8 and 9!

Spent some time getting my air sensors tied together into a dashboard. :-D 
@movq@www.uninformativ.de so the pathfinding puzzle has arrived?
@movq@www.uninformativ.de you are probably right.. there seems to be a final 10 trend found over on Reddit.
@movq@www.uninformativ.de tossing around inline ASM for the AoC..
In the holiday spirit i have donned my Santa hat. (shamelessly stolen from @movq@www.uninformativ.de)
@movq@www.uninformativ.de I wish they just muted them out instead of making it an awfully loud meep sound.
Around and around you go. When we sync up? Nobody knows!
With the global ordering for our private leader board we are all 1st place winners!!
I have been really impressed with the cool visualizations in pygame that @gereleth over on Twitter has been making. #AdventOfCode
@prologic@twtxt.net day 6 is super easy if you have int64 and some binomial theory. Skip ahead for the easy stars and catch up!
Oh.. Right. Need subtract and divide too for the binomial
@movq@www.uninformativ.de it shouldn’t need a full bignum implementation right? Just some left and right shifts for the sq/sqrt and carry for the addition right?
So today’s #adventofcode was solved with no programming. Just a bit o maths and wolfram/alpha
The word forms is part two. In this one you want to find the first digit and last digit. Think searching ‘1’ - ‘9’
Its the latest ryzen 7 chipset for laptop/mini form factor.
I am very surprised about the times others are getting. I guess that’s the difference between interpreted and compiled showing.
took a few attempts.. but i managed to do it in half the time!
@movq@www.uninformativ.de It took a little over a minute on my machine.. i should try to make it multi threaded.. 🤔

How did so many get the first star within the first 3 mins? 
@eapl.me@eapl.me I have many fond memories of Turbo pascal and Turbo C(++). They really did have a great help system. And debug tools! Its rare for language docs to be as approachable. QBasic was great. As was PHP docs when I first came into web.
@jason@jasonsanta.xyz if you do see this.. Welcome back! 👋🏼
This day one advantage of code was pretty neat looking.

I could have made my search smarter using a prefix search rather than scanning the full buffer for each iteration.
@movq@www.uninformativ.de haha! I’m sure they had fun working around stuff like nineight
@movq@www.uninformativ.de Dang. Really going overboard with this!
@prologic@twtxt.net I didn’t have to do much backtracking. I parsed into an AST-ish table and then just needed some lookups.
The part 2 was pretty easy to work into the AST after.
https://git.sour.is/xuu/advent-of-code-2023/commit/c894853cbd08d5e5733dfa14f22b249d0fb7b06c

Day 2 used lots of Cut and Split.
Oof. Its quite everywhere here in my area. Hope its not too bad there.
@prologic@twtxt.net oh snap!
If anyone is doing advent of code this year i created a private leader board for twtxters! 3463928-93bf7cfa
@prologic@twtxt.net you must not have any friends with plex shares. I got one. 
@prologic@twtxt.net I long ago moved my evernote content to joplin.
Neat.. Gitea cloud for a hosted alternative to github and gitlab. https://blog.gitea.com/gitea-cloud/
Interesting thing happening over on Xitter. Apparently some of the women in tech accounts are being exposed as being run by men that hire women to pose for images/videos. They would be invited to tech conferences but would always drop out last minute.
Makes me wonder if maybe there is need for a sort of verifiable web of trust is needed where influencers can be proven as authentic by others. This will only get worse as AI generative content gets pushed into our feeds.
