I’ve had the ActivityPub plugin active on this blog for a while now and it’s been happily federating to mastodon for just as long. However it never worked on lemmy, and I always assumed it was just not set for it and was primarily focused on microblogging since lemmy was not even mentioned in the supported software.
Through some back and forth between the developers and me, I eventually started experimenting with the plugin settings, trying to see if any of them would make it behave in a way that lemmy could understand, until one of the options finally did the trick.
As a result, this WordPress blog is now happily existing as a lemmy community !dbzer0.com@dbzer0.com
’tis a bit of a silly community name, but it works.
Unfortunately the previous posts on this blog are not retrieved automatically, so you won’t be able to see them or their comments in the community, but one can search for a blog url in lemmy and it will discover it and open it for comments. Any comments posted there should also appear as comments under the posts here which is pretty neat!
So if you’re on lemmy or piefed, just visit its community from your own instance and subscribe to it, and new blogposts will appear directly in your lemmy feed. I love apub!
Many thanks to both pferfferle (the apub plugin developer) and the lemmy developers who looked into this!
leave a comment (from lemmy?) to let me know what you think.
From the first moment I first went online in 1996, forums were the main place to hang out. In fact the very first thing I did was join an online forum run by the Greek magazine “PC Master” so I could directly to my favourite game reviewers (for me it was Tsourinakis, for those old enough to remember).
Whoever didn’t like the real-time nature of the IRC livechat, forums were all the rage and I admit they had a wonderful charm for the upcoming teenager who wanted to express themselves with fancy signatures and some name recognition for their antics. Each forum was a wonderful microcosm, a little community of people with a similar hobby and/or mind-frame.
BBcode-style forums took the web 1.0 internet by storm and I remember I had to juggle dozens of accounts, one for for each one I was interacting with. Basically, one for each video game (or video game publisher) I was playing, plus some Linux distros, hobbies, politics and the like. It was a wonderful mess.
But a mess it was, and if the dozens of accounts and constant context switching barely enough to handle for an PC nerd like myself, I can only imagine how impenetrable it was for the less tech-savvy. Of course, for people like me this was an added benefit, since it kept the “normies” out and avoided the “Eternal September” in our little communities.
However the demand for places accessible for everyone to discuss was not missing, it was just unfulfilled. So as soon as Web 2.0 took over with the massive walled gardens of MySpace, Facebook, Twitter and so on, that demand manifested and the ability for anyone to create and run a forum within those spaces regardless of technical competency or BBcode knowledge, spawned thousands of little communities.
Soon after Digg and then Reddit came out, and after the self-inflicted implosion of Digg, Reddit along with Facebook became the de-facto spot to create and nurture new async-discussion communities, once they added the functionality for everyone to create one and run it as they wanted.
But the previously existing BBcode forums still existed and were very well established. Places like Something Awful had such strong communities that they resisted the pull of these corporate walled gardens for a long time. But eventually, they all more or less succumbed to the pressure and their members had an exodus. What happened?
I’m not a researcher, but I was there from the start and I saw the same process play out multiple times in the old forums I used to be in. Accessibility and convenience won.
There’s a few things I attribute this to.
The executive costs to create a new forum account is very high. Every time you want to join one, you need to go through making a username (often trying to find one that’s not taken, so now you have to juggle multiple usernames as well), new password, captchas, email verifications, application forms, review periods, lurker wait times and so on. It’s a whole thing and it’s frustrating to do every time. Even for someone like me who has gone through this process multiple times, I would internally groan for having to do it all over again.
Keeping up to date was a lot of work. Every time I wanted to keep up to date with all my topics, I had to open new tabs for each of my forums and look at what’s new is going on. The fact that most of the forums didn’t have threaded discussions and just floated old discussions with new replies to the top didn’t help at all (“thread necromancy” was a big netiquette faux-pas). Eventually most forums added RSS feeds, but not only were most people not technical enough to utilize RSS efficiently (even I struggled), but often the RSS was not implemented in a way that was efficient to use.
Discoverability was too onerous. Because of (1) Many people preferred to just hang out in one massive forum, and just beg or demand new forum topics to be added for their interests so they wouldn’t have to register, or learn other forum software and interact with foreign communities. This is how massive “anything goes” forums like Something Awful started, and this also started impacting other massive forums like RPGnet who slowly but surely expanded to many more topics. Hell almost every forum I remember has politics and/or “out of topic” sections for people to talk without disrupting the main topics because people couldn’t stop themselves. And where the forum admins didn’t open new subject areas, the bottom-up pressure demanded that solutions be invented in the current paradigm. This is how you ended up with immortal threads, thousands of pages deep for one subject, or regular mega-threads and so on. Internet life found a way.
Forum admins and staff were the same petty dictators they always were and always will be. Personality cults and good ole boys clubs abounded. People were established and woe to anyone who didn’t know enough to respect it, goddammit! I run into such situations more than once, even blogged about it back in the day. But it was an expected part of the setup, so people tolerated it because, well what else will you do? Run your own forum? Who has the time and knowledge for that? And even if you did, would anyone even join you?
And so, this was the paradigm we all lived in. People just declared this is how it had to be and never considered any proper interactivity between forums as worth the effort. In fact, one would be heavily ridiculed and shunned for even suggesting such blasphemous concepts
That is, until Facebook and Reddit made it possible for everyone to run their own little fief and upended everything we knew. By adding forum functionality into a central location, and then allowing everyone to create one for any topic, they immediately solved so many of these issues.
The executive cost to join a new topic is very low. One already has an account on Reddit and/or Facebook. All they have to do is press a button on the subreddit, group they want to join. At worst they might need to pass an approval, but they get to keep the same account, password and so on. Sure you might need to juggle 1-3 accounts for your main spaces (Reddit, Facebook, Discord), but that’s so much easier than 12 or more.
Keeping up to date is built-in. Reddit subscriptions allows one a personalized homepage, Facebook just gives you your own feed, discord shows you where there’s activity and so on. Of course the corporate enshittification of those services means that you’re getting more and more ads along masquerading as actual content and invisible algorithms are feeding you ragebait and fearbait to get you to keep interacting at the cost of your mental and social health, but that is invisible for most users so it doesn’t turn them off.
Discoverability is easy. Facebook randomly might show you content from groups you’re not in, shared by others. Reddit’s /r/all feed showed posts from topics you might not even know existed and people are quick to link to relevant subreddits. Every project has its own discord server link and so on.
The fourth forum problem of course was and can never be solved. There will always be sad little kings of small sad little hills. However solving 1-3 meant that the power of those abusing their power as moderators was massively diminished as one could just set up a new forum in a couple of minutes and if there was enough power abuse, whole communities would abandon the old space and move to the new one. This wasn’t perfect of course, as in Reddit, only one person could squat one specific subreddit, but as seen with successful transitions from /r/marijuana to /r/trees, given enough blow-back, it can certainly be achieved.
And the final cherry on top is that places like Reddit and discord are just…easier to use. Ain’t nobody who likes learning or using BBcode on 20-year-old software. Markdown became the norm for a reason due to how natural it is to use. Add to that less restrictions on uploads (file size, image size etc) and fancier interfaces with threaded discussions, emoji reactions and so on, and you get a lot of people using the service instead of trying to use the service. There are of course newer and better forum software like the excellent Discourse, but sadly that came in a bit too late to change momentum.
So while forums never went away, people just stopped using them, first slowly but accelerating as time passed. People banned just wouldn’t bother to create new accounts all over again when they already had a Facebook account. People who wanted to discuss a new topic wouldn’t bother with immortal mega-threads when they could just join or make a subreddit instead. It was a slow-burn that was impossible to stop once started.
10-15 years after Reddit started, it was all but over for forums. Now when someone wants to discuss a new topic, they don’t bother to even google for an appropriate forum (not that terminally enshittified search engines would find one anyway). They just search Reddit or Facebook, or ask in their discord servers for a link.
I admit, I was an immediate convert since Reddit added custom communities. I created and/or run some big ones back in the day, because I was naive about the corporate nature of Reddit and thought it was “one of the good ones”, even though I had already abandoned Facebook much earlier. It was just so much easier to use one Reddit account and have it as my internet homepage, especially once gReader was killed by Google.
But of course, as these things go, the big corporate gardens couldn’t avoid their nature and eventually once the old web forums were abandoned for good and people had no real alternatives, they started squeezing. What are you gonna do? Set up your own Reddit? Who has the time and knowledge for that? And even if you did, would anyone even join you?
Nowadays, I hear a lot of people say that the alternative to these massive services is to go back to old-school forums. My peeps, that is absurd. Nobody wants to go back to that clusterfuck I just described. The grognards who suggest this are either some of the lucky ones who used to be in the “in-crowd” in some big forums and miss the community and power they had, or they are so scarred by having to work in that paradigm, that they practically feel more comfortable in it.
No the answer is not anymore an archipelago of little fiefdoms. 1-3 forbid it! If we want to escape the greedy little fingers of u/spez and Zuckeberg, the only reasonable solution is moving forward is activitypub federated software.
We have already lemmy, piefed, and mbin, who already fulfill the role of forums, where everyone can run their own community, while at the same time solving for 1-3 above! Even Discourse understood this and started adding apub integration (although I think they should be focusing on threadiverse interoperability rather than not microblogging.)
Imagine a massive old-school forum like RPGnet migrating to a federated software and immediately allow their massive community access to the rest of the threadiverse without having to go through new accounts and so on, while everyone else gets access to the treasure trove of discussions and reviews they have. It’s a win-win for everyone and a loss for the profiteers of our social media presence.
Not only do federated forums solve for the pain points I described above, but they add a lot of other advantages as well. For example we now have way less single points of failure, as the abandonment of a federated instance doesn’t lose its content which continues living in the caches of the others who knew about it and makes it much easier for people to migrate from one lemmy instance to another due to common software and import/export functionalities. There’s a lot of other benefits, like common sysadmin support channels, support services like fediseer and so on.
These days, I see federated forums as the only way forward and I’m optimistic of the path forward. I think Reddit is a dead site running and the only way they have to go is down. I know we have our own challenges to face, but I place far more trust in the FOSS commons than I do in corporate overlords.
Recently a maintainer from jinteki.net contacted me about getting the license for the A:NR sound effects I had used in the OCTGN implementation to reuse in jinteki and casually mentioned that the Archer ICE noise was the coolest one. It had until now never occurred to me that people might appreciate the various sound effects I had inserted into the game back then for the flavour, so I did a quick search and run into this cute video about it (you can hear archer at the 13:00 mark).
Fascinating! I always like to make my games as flavorful as possible, and especially given the limitations of OCTGN, some flavour was sorely needed. So I had added custom fonts, little flavour blurbs in significant actions and finally I scoured the internet for hours and hours to find the sound effects which fit the cyberpunk theme of the various actions.
These were always meant to be just little things in an obscure game, so I’m kinda pleasantly surprised that some of them have received this sort of cult status in the netrunner community. Very cool. Hopefully these sound effects will find a second life in jinteki.net
If you want to check what the OCTGN game looked like, I have a tutorial video here, and I also have a bunch of videos about it on my youtube channel.
The second fediverse canvas event just concluded and I’m very happy how this turned out. In case you don’t know what this is. Check out this post and then take your time to go and explore the second canvas in depth before it’s taken down, and look for all the interesting and sometimes even hidden pieces of pixel art.
This time I had a more interesting idea to participate. I decided to draw the Haidra Org logo. I didn’t expect a massive support, but was pleasantly surprised with how many people joined in to help create it after my initial post about it and my announcement on the AI Horde discord server. Some frontends like horde-ng even linked to it with an announcement.
Almost as soon as it started, we ended up conflicting in our placement with someone who was drawing a little forest on just below and to our left. I decided that they can have the foreground since we had plenty of space available which avoided any fighting over pixels. All in all, we managed to complete it within half a day or so which is pretty cool I like to think and we even got a small “garden” so to speak.
Afterwards I thought it would be interesting to have the Haidra tendrils “touch” various points of importance or sprites that I like. I decided to extend out as if we’re made of water and a lot of other “canvaseers” joined in to help which I found really sweet.
First we extended towards the (then) center of the canvas (top left on the featured image above), passing next to the Godot logo, below OSU and finally reached the explosion of the beams. That took most of the first day but people were still pretty active, even though the infrastructure of the event had already started buckling under its own success.
Fortunately as we could “flow” like water and even “go under” other pixelart, we didn’t encounter any resistance in our journey, and a lot of people gave us a helping hand as well.
Once this was achieved on a whim, I decided to double down on the “river” similaity, and drew a little 17px pirate ship to show our roots and went to bed. When I woke up next morning, I was surprised to discover a Kraken was attacking it making a really cool little display of collaborative minimalistic art.
This kind of thing is why I love events like these. I love emergent stuff like these and seeing people putting the own little touches on what other started is awesome!
The next day the canvas had extended to be double in size and so a whole new area to the right was available, I had already noticed someone had created a little pirate banner towards the new canvas center, but it was alone and sad. So I decided we should try to give it a little bit of that Haidra embrace. So a long journey started with a new tendril to reach it. I had a rough idea of the path to follow as the direct route was blocked, but as soon as other started adding to it, it almost took a life of its own on its journey.
Eventually, towards the middle of the second day we reached it, passing under Belgium, through some letters and crossing the big under-construction trans flag before going over piracy, before I spawned yet another pirate ship before waterfalling down onto the mushroom house.
At this point, the whole event took a dramatic turn as the performance problems had become so severe, that the admin decided to take the whole thing down to fix them, rather than let people get frustrated. This took half a dozen hours or so, and even though the event was extended by 24 hours to make up for it, the event momentum was kneecapped as well.
Once the canvas was back up for the third day, the next objective I had was a much longer journey to try and touch The Void that was extending from the top right. When I started, the path was still mostly empty, but as we moved towards it, the canvas became more more congested, forcing us to take some creative detours to avoid messing with other art.
All in all, we flowed over the Factorio cog, creating a little lake and spawning a rubber duckie in the process. Then through the second half of the trans flag, which caused a minor edit war, as the canvaseers thought we were vandalizing. Then the way up and over the massive English flag was sorta blocked, so we had to take a detour and slither between the Pokemon to its left first.
Until finally we reached the top of the English flag, where I took a little creative detour to draw a little naval battle. My plan was to have an English brigantine fighting with two pirate sloops, but as soon as I finished it, other jumped in with their own plans. First one of my pirate ships revealed itself as a Spanish privateer instead (which I suspect was a reference to the recent football events). And then over the course of the next two days, the three ships kept changing allegiances every couple of hours. Quite the little mini-story to see unfold.
Finally we were almost at our final objective, only to discover that our final objective was not there anymore. The Void had been thoroughly contained and blocked by a massive cat butler (catler?). The only thing left to touch, was a single solitary void tendril on the top. Surprisingly, as soon as we reached it, it livened and flourished into life, which was certainly not my original idea, but I went with it happily.
Having achieved all I wanted to do, and with the event (and the day) drawing to a close, I decided there’s no point setting any more goals and just left those interested start extending Haidra on a whim. You can see my final post here, which also links to all my previous posts, which also contain some historic canvas images, showing the actual state of the board at the time of the posting.
All in all, I had a lot of fun, and enjoyed this way more than Reddit /r/place which is botted to hell and back, making contributions by individual humans practically meaningless. Due to the lack of significant botting, not only was one’s own pixels more impactful, but humans tended to mostly collaborate instead of having scripts mindlessly enforcing a template. This ended with a much more creative canvas, as people worked off others ideas and themes, and where there was conflict, a lot of the time a compromise solution was discovered where both pieces of art could co-exist.
The conflict points tended to be political, as it so often happens. For example the Hexbears constantly trying to make the Nato flag into a swastika, or some effectively people rehashing the conflict around the Israel colonization of Palestine in pixel conflict form.
Some other things of interest:
I mentioned that the Spanish seem to have boarded and overtaken my pirate ship, and someone drew a little vertical ship coming up the stream for reinforcements. ❤️
Stus and AmongUs everywhere, sometimes in negative space, or only visible in the heatmap. Can you find them all?
The Void getting absolutely bodied when it tried to be destructive, but being allowed to extend a lot more when they actually played nice with other creations.
The amount of My Little Pony art is too damn high!
Pleasantly little national flag jingoism on display!
A very healthy amount of anarchist art and concepts and symbols. Well done mates! Ⓐ
You’ll notice all of these are frustrations about the (lack) of sufficient moderation in the tool-set of lemmy. This is typically coming from a lemmy admin’s perspective and the things that are very important to protect themselves and their communities.
In the discussions around these issues, a few common arguments have been made, which while sounding reasonable at face value, I think are the wrong thing to say to the situation at hand. The problem is somewhat that the one making these arguments feels like they’re being more than fair, while the ones receiving them feel dismissed or disrespected.
Before I go on, I want to make clear that I am writing this out of a place of support. I have been supporting lemmy years before the big lemmy exodus and after I made my own lemmy instance, I have created dozens of third party tools to help the ecosystem, because I want lemmy to succeed. That is to say, I’m not a random hater. I am just dismayed that the community is splintering like this, out of what seems to me, like primarily a communication issue.
So one of the analogies made in the sunaurus thread, likened lemmy development to designing a playground. It strikes me that this analogy is perfect, but not for the reason the one making it expects. Rather, it is perfect for exemplifying how someone coming from wholeheartedly supporting FOSS developers might still misjudge the situation and escalate a situation through miscommunication.
In this analogy, the commenter likened lemmy development like building a playground and external people asking for some completely unrelated feature, like a bird-watching tower, and expecting the developers to give it priority. The problem here is that the analogy is flawed. The developers are not building a playground for themselves. They’re building a playground schematic, which they expect people would and should deploy in many other locations.
Some people might indeed ask for “bird-watching observation posts” in such a schematic and it would be more than fair to ask them to build it themselves. but it is fallacious to liken any and all requests as something as out of scope as this. Some people might request safety features on the playground and those should absolutely be given more priority. We already know what can happen if you design a shitty playground, even if you give it for free!
To extend this analogy, the other lemmy admins, are not asking for luxury features. They are asking for improvements in the safety of the playground. Some people point out that metal slides become dangerous based on the weather. Some other point out that the playgrounds might be built in very unsafe areas, so a fence to protect the children from predators should be mandatory.
And here is the disconnect in communication happens. The overworked developer is already busy designing the next slide which can get them paid, or making sure things don’t break down as fast etc, and they perceive the safety requests as “luxury” items, someone should deal with themselves. However for the people who have to deal with upset parents and missing children, this dismissive attitude come out as downright malicious.
And thus you have a situation where both sides see the other are unreasonable. The devs see the people asking for the safety features as entitled, while the people who are suffering through the lack of those safety features perceive the developers as out-of-touch and dismissive.
Leave such a situation to fester long enough, and you start to get the exact situation that we have now. The Lemmy software starting to get a bad reputation in the areas concerned about most safety while forks and rebuilds are popping up.
All of this hurts the whole FOSS ecosystem by splintering development effort into multiple projects instead of collaborating on a single one. It turns our strength into a weakness!
This also brings me to another argument I see lemmy devs making somewhat too often. That they don’t have anything to gain from a larger community and just get more headaches. I always felt this was a patently absurd statement!
The lemmy devs are making more than 3K a month from lemmy. Enough that they are claiming they’re working on lemmy full-time. These funds don’t come because they’re running or developing a single forum for themselves. They come because they provide the “playground schematic”. If the community splinters into other software than lemmy, naturally the funds going towards lemmy development will likewise dry up.
This statement is completely upside down. The more people there are using and hosting lemmy, the more the lemmy developers benefit.
I would argue, the people lemmy developers should be listening to most are exactly the people hosting lemmy instances. These are the people putting incalculable hours into running and maintaining the servers and often paying out of pocket per month, for giving a service to others. Each admin is basically free value to the lemmy developers.
My position is in fact is that this scales down like layers. Lemmy Admins need to listen to instance admins most. Instance admins need to listen to community mods most. And finally community mods should listen to their users most. In this way you create bottom-up feedback mechanism, that doesn’t overwhelm any single person easily and everyone has a chance to be heard.
In AI Horde, I follow a similar approach. The segment of my community I listen to the most is in fact not the ones who are giving me money. It’s the ones who are providing their free time and idle compute for no other benefit than their own internal drive: The workers. They are effectively using their time for the benefit the whole ecosystem, which indirectly benefits me most. Without the workers, there would practically be no AI Horde, even if I am the only remaining. Likewise, without lemmy admins, lemmy as a software would be dead, even if the lemmy.ml people kept hosting forever.
So what can be done here. I think an important aspect here is to make sure we are talk in the same wavelength. Cutting down on miscommunication is very important to avoid exacerbating an already precarious situation.
Secondly, it’s totally understandable that lemmy devs don’t have enough time for everything. But likewise, there’s a ton of people who need safety features but can’t get them. As such, in my opinion priority should be put into making the frameworks that more easily allows people to extend lemmy functionality, even if it doesn’t match the lemmy developers visions, or immediate roadmap.
For this reason I strongly suggest that effort should be put into developing a plugin framework for lemmy. Ironic to suggest a completely different feature when the problem is too many things to do, but this specific feature is meant to empower the larger community to solve their own problems easier. So in the long term, it will massively reduce the incoming demands to the lemmy developers.
In the meantime, I do urge people to always consider that there’s always a human behind the monitor on the other side. A lot of time people don’t have the skills to effectively communicate what they mean, which is even worse in text form. We all need be a bit more charitable on what the other side is trying to say, especially when we’re trying to collaborate for a common FOSS project.
A couple days ago, someone posted on /0 (the meta community for the Divisions by zero) that the incoming federation from lemmy.world (the largest lemmy instance by an order of magnitude) is malfunctioning. Alarmed, I started digging in, since a federation problem with lemmy.world will massively affect the content my community can see.
As always my first stop was the Lemmy General Chat on Matrix where I asked the lemmy.world admins if this appears to be something on their end. To their credit both their lead infra admin and the owner himself jumped in to assist me, changing their sync settings, adding custom DNS entries and so on. Nothing seemed to help.
But the problem is must still be somewhere in lemmy.world I thought. It’s the only instance where this is happening and they upgraded to 0.19.3 recently, so something must have broken. But wait, this didn’t start immediately after the upgrade. Someone pointed out this very useful federation status page, which kinda point that the problem is only on lemmy.world.
Not quite, other big instances like lemmy.ml and lemm.ee were not having any issues with federation with lemmy.world (even though 2 dozen others like lemmy.pt were), and they are as big if not bigger than lemmy.dbzer0.com. A problem originating from lemmy.world cannot be possibly affecting only some specific instances. To make matters worse, both me and lemmy.ml are using the same host (OVH), so I couldn’t even blame my hosting provider somehow.
So obviously the main culprit it somewhere in my backend, right? Well, maybe. Problem is, none of the components of my infrastructure were overloaded, everything sitting between 5-15% utilization. Nothing to even worry about.
OK, so first I need to make sure it’s not a network issue somehow specifically between me and lemmy.world specifically. I know OVH gave me a bum floating IP in the past and were completely useless at even understanding that their floating IP was faulty, so I had to stop using it. Maybe there’s some problem with my loadbalancers.
Still, I’m using haproxy, which is nothing if not fast and rock solid. So I didn’t really suspect the software. Rather, maybe it’s a network issue with the LB itself. So first thing I did is double the amount of Loadbalancers in play, by setting my DNS record to point to my secondary LB at the same time. This should lessen the amount of traffic hitting my LB and even take them at a completely different VM, and thus point if the problem is on the haproxy side. Sadly, this didn’t improve things at all.
OK so next step, I checked how long a request takes to return from the backend after haproxy sends it over. The results were not good.
I don’t blame you if you cannot read this, but what this basically says is that a request hitting a POST on my /inbox, took between 0.8 and 1.2 seconds. This is bad! This is supposed to be a tiny payload to tell you an event happened on another instance, it should be practically instant.
Even more weird, this is affecting all instances, not just lemmy.world. So this is clearly a problem on my end, but it also confused me. Why am I not having troubles with other instances? The answer came when I was informed that 0.19.3 added a brand new, special new federation queue.
You see, the old versions of lemmy used to send all federation actions over as soon as they received them. Fire and forget style. This naturally lead to federation events being dropped due to a myriad of issues, like network, downtimes, gremlins etc. So you would lose posts, comments and votes, and you would (probably) never realize.
The new queue added order to this madness, by making each instance send its requests serially. A request would be sent again and again until it succeeded. And the next one would only be sent if the previous one was done. This is great for instances not experiencing issues like mine. You see, at this point, I was processing 1 incoming federation request per second approximately, while lemmy.world was sending around 3. Even worse, I would occasionally timeout as well by exceeding 10 seconds to process, causing 2 more seconds or wait time.
Unlike lemmy.world, other federating instances to mine didn’t have nearly as much activity, so 1 per second was enough to keep up to sync with them. This explained why I seemingly was only affected by lemmy.world and nobody else. I was somewhat slow, but only slow enough to notice if the source had too much traffic.
OK, we know the “what”, now we needed to know the “why”.
At this point I’m starting to suspect something is going on my Database. So I have to start digging into stuff I’m really not that familiar. This is where the story gets quite frustrating, because there’s just not a lot of admins in the chat who know much about the DB stuff of lemmy internals. So I would ask a question, or provide logs, and then had to wait sometimes hours for a reply. Fortunately both sunaurus from lemm.ee and phiresky were around, who could review some of my queries.
Still, I had to know enough sql to craft and finetune those queries myself and how to enable things like pg_stat_activity etc.
Through trial and error we did discover that some insert/update queries were taking a bit too much time to do their thing, which could mean that we were I/O bound. Easy fix, disable synchronous_commit, sacrificing some safety for speed. Those slow queries went away, but the problem remained the same. WTF?!
There was nothing else clearly slow in the DB, so there was nothing more we could do there. So my next thought was, maybe it’s a networking issue between my loadbalancers and my backend. OK so I needed to remove that from the equation. I set up a haproxy directly on top of my backend which would allow me to go through the loopback interface and have 0 latency. For this I had to ask the lemmy.world admins to kindly add lemmy.dbzer0.com directly to their /etc/hosts file so they alone would hit my local haproxy.
No change whatsoever!
At this point I’m starting to lose my mind. It’s not networking between my LB and my backend, and it’s not the DB. It has to be the backend. But it’s not under any load and there’s no errors. Well, not quite. There’s some “INFO” logs which refer to lost connections, or unexpected errors, but nobody in the chat seems to worry about them.
Right, that must mean the problem is networking between my backend and my database, right? Unlike most lemmy instances, I keep my lemmy DB and my backend separated. Also, the DB has a limited amount of connections and lemmy backend itself limits itself to a small pool of connections. Maybe I run out of connections because of slow queries?
OK let’s increase that to a couple thousands and see what happens.
Nothing happens, that’s what happens. Same 1 per second requests.
As I’m spiraling more and more towards madness, and the chat is running out of suggestions, sunaurus suggests that he adds some extra debugging to lemmy and I will run that to try and figure out which DB query is losing time. Great idea. Problem is, I have to compile lemmy from scratch to do that. I’ve never done that before. Not only that, I barely know how to use docker in the first place!
Alright, nothing else I can do, got to bite that bullet. So I clone the lemmy backend and while waiting for sunaurus to come online, I start hacking at it to figure out how to make it compile a docker lemmy backend from scratch. I run into immediate crashes and despair. Fortunately nutomic (one of the core devs) walked by and told me the git commands to run to fix it, so I could proceed in cooking my very first lemmy container. Then nutomic helped me realize I don’t need to set up a whole online repo to transfer my docker container. The more you know…
Alright, so I cooked a container and plugged it onto a whole separate docker infra, which is only connected to the lemmy.world loadbalancer, so I can remove all other logs from anything but federation requests. So far so good.
Well, not quite, unfortunately I forgot that the “main” branch of lemmy is actually the development branch and has untested code in there. So when I was testing my custom docker deployment, I migrated my DB to whatever the experimental schema is on main. Whoops!
OK, nothing seemingly broke. Problem for a different day? No, just foreshadowing.
Finally sunaurus comes back online and gives me a debug fork. I eagerly compile and deploy it on prod and then send some logs to sunaurus. We were expecting we’d see 1 or 2 queries that were struggling, so maybe a bad lock situation somewhere. We did not expect we’d see ALL queries, including the most simple query such as lookup a language, take 100ms or more! That can’t be good!
Sunaurus connects the dots and asks the pertinent question: “Is your DB close to the Backend, geographically?”
Well, “Yes”, I reply, “I got them in the same datacenter”. “Can you ping?” he asks.
OK, I ping. 25ms. That’s good right? Well, in isolation, that’s great. When it’s not so great is when talking about backend-to-DB communication! This like 1000s km distance.
You see, typically a loadbalancer just makes one request to the backend and gets one reply, so a 25ms roundtrip is nothing. However a backend is talking to the DB a lot. In this instance, for every incoming federation action the backend does like 20 database calls, to verify and submit. Multiply each of these by 25+25 roundtrip and you got 1000ms extra before any actual processing on the DB!
But how did this happen? I’m convinced all my servers are in the same geographic area. So I go to my provider panel and check. Nope, all my server BUT the backend are in the same geographic area. My backend happens to be around 2000 km away. Whoops!
Turns out, when I was migrating my backend back in the day I run into performance issues, I failed to pay attention to that little geographic detail. Nevertheless It all worked perfectly well until this specific set of circumstances where the biggest lemmy instance upgraded to 0.19.3 which caused a serial federation, which my slow-ass connection couldn’t keep up. In the past, I would just get flooded by sync requests by lemmy.world as they came. I would be slow, but I’d process them eventually. Now, the problem became obvious.
Alright, it’s time to put up my sleeves and it’s migrate servers! Thank fuck I have everyone written in Ansible as code, so the migration was relatively painless (other than slapping Debian 12 around to let me do fucking docker-compose operations with python, goddamnit!)
A couple of hours later, I had migrated my backend to the same DC as the Database, and as expected, suddenly my ingestion rate for federation actions was in the order of 50ms, instead of 1000ms. This means I could ingest closer to 20 actions per sec from lemmy.world and it was getting just 3/s new from its userbase. Finally we started catching up!
All in all, this has been a fairly frustrating experience and I can’t imagine anyone who’s not doing IT Infrastructure as their day job being able to solve this. As helpful as the other lemmy admins were, they were relying a lot on me knowing my shit around Linux, networking, docker and postgresql at the same time. I had to do extended DB analysis, fork repositories, compile docker containers from scratch and deploy them ad-hoc etc. Someone who just wants to host a lemmy server would give up way earlier than this.
For me, a very stressing component was the lack of replies in the chat. I would sometimes write pages of debug logs, and there was no reply from anyone for 6 hours or more. It gave me the impression that nobody had any clue what to do to help me and I was on my own. In fact, if it wasn’t for sunaurus specifically, who had enough Infrastructure, Rust and DB chops to get an insight out of where it was all going wrong, I would probably still be out there, pulling my hair.
As someone hosting a service like this, especially when it has 12K people in it, this is very scary! While 2 lemmy core developers were in the chat, the help they provided was very limited overall and this session mostly relied on my own skills to troubleshoot.
This reinforced in my mind that as much as I like the idea of lemmy (or any of the other threadiverse SW), this is only something experts should try hosting. Sadly, this will lead to more centralization of the lemmy community to few big servers instead of many small ones, but given the nature of problems one can encounter and the lack of support to fix them if they’re not experts, I don’t see an option.
Fortunately this saga ended and we’re now fully up to sync with lemmy.world. Ended? Not quite. You see today I realized I couldn’t upload images on my instance anymore. Remember when I started the development instance of lemmy by mistake from main? Welp that broke them. So I had to also learn how to downgrade a lemmy instance as well. Fortunately sunaurus had my back on this as well!
To spare some people the pain, I’ve sent a PR to the lemmy docs to expand the documentation for building docker containers and doing troubleshooting. My pain is your gain.
This also gave me an insight about how the federation of lemmy will eventually break when a single server (say, lemmy.world) grows big enough to start overwhelming even servers who are not badly setup like mine was. I have some ideas to work around some of this so I plan to a suggestion on how to become more future proof, which would incidentally prevent the same issue which happened to me in the first place.
In the meantime, enjoy the Divisions by zero, which as a result of the migration should now feel massively faster as well!
Looks like someone really kicked the hornet’s nest recently on mastodon by announcing (not even deploying) a Mastodon-BlueSky bridge. Just take a look at the github comments here to get an idea of how this was received.
Plenty of people way more experienced than myself have weighted on this issue so I don’t feel the need to leave my two cents. However I wanted to talk about a very common counter-argument made towards those who do not want such bridges to exist. Namely, that Fediverse already provides the tools towards not having such a bridge be an issue: The allow-list model.
The idea being that if your ActivityPub server by default rejects all federation except towards trusted instances, then such bridges pose no problems whatsoever. The bridge (and any potential undercover APub scrappers) would not be able to get to your instance anyway.
Naturally, the counterargument is that this is way too limiting to one’s reach, and they shouldn’t be forced into isolation like this. Unfortunately the alternative here appears to try and scold others into submission, and this is unlikely to be long term solution. Eventually the Eternal Septemberwill come to the Fediverse. If you spent the past few years relying on peer pressure to enforce social norms, then the influx of people who do not share your values is going to make that tactic moot.
In fact, we can already see the pushback to the scolding tactics unfolding right now.
The solution then has to be a way to improve the way we handle such scenarios. Improve the tooling and our tactics so that such bridges and scrappers cannot be an issue.
A lot of the frustration I feel also comes down to the limited set of tools provided by Mastodon and other Fediverse services. A lot of the time, the improvement of tooling is stubbornly refused by the privileged core developers who don’t feel the need to support the needs of the marginalized communities. But that doesn’t mean the tooling couldn’t be expanded to be more flexible.
So let’s think about the Allow-List model for a moment. The biggest issue of an Allow-List is not necessarily that the origin server restricts themselves from the discussion. In fact they’re probably perfectly happy with that. The problem is that if this became the norm, it massively restricts the biggest strength of the Fediverse, which is for anyone to create and run their own server.
If I make a new server and most of everyone I want to interact with is in Allow-List mode, how do I even get in? We then have to start creating informal communication channels where one has to apply to join the allow-circle. Such processes have way too many drawbacks to list, such as naturally marginalizing Neurodivergent people with Rejection Sensitivity Dysphoria, balkanizing the Fediverse, empowering whisper networks and so on.
I want to instead suggest an alternative hybrid approach: The Feeler network. (provisional name)
The idea is thus: You have your well protected servers in Allow-List mode. These are the servers which require protection from constant harassment when their posts are spread publicly. These servers have a few “Feeler” instances they trust on their allow-list. Those servers in turn do not have an allow-mode turned on, but rely on blocklist like usual. Their users would be those privileged enough to be able to handle the occasional abuse or troll coming their way before blocking them.
So far so good. Nothing changes here. However what if those Feeler servers could also use the wider reach to see which instances are cool and announce that to their trusted servers? So a new instance appears in your federation. You, as a Feeler server, interact with them for a bit and nothing suspicious happens, and their users seem all to be ideologically aligned enough. You then add them into a public “endorsed list”. Now all the servers in your trust circle who are in allow-mode see this endorsement and automatically add them to their allow-lists. Bam! Problem solved. New servers have a way to be seen and eventually come into reach with Allow-List instances through a sort of organic probation period, and allow-listed servers can keep expanding their reach without private communications, and arduous application processes.
Now you might argue: “Hey Db0, yes my feelers can see my allow-list server posts, but if they boost them, now anyone can see them, and now they will be bridged to bluesky and I’m back in a bad spot!”
Yes this is possible, but also technically solvable. All we need to do is to make the Feeler servers only federate boosted posts from servers in allow-mode, to the servers that the ones in the allow-list already allow. So let’s say Server T1 and T2 are instances in allow-list mode which trust each other. Server F1 is a Feeler server trusted by T1 and T2. Server S1 is an external instance that is not blocked by F1, but not yet endorsed either. User in F1 boosts a post from T1. Normally a user in S1 would see that post by following that user. All we need to do is to change the software so that if F1 boosts a post from T1, the boost would only federate towards T2 and other instances in T1’s allow-list, instead of everyone. Sure this would require a bit more boost complexity, but it’s nothing impossible. Let’s call this “protected boost”.
Of course, this would require all Apub software to expose an “Endorsement” list for this to work. This is where the big difficulty comes from, as you now have to herd the cats that are the multitude of APub developers to add new functionality. Fortunately, this is where tools like the Fediseer can cover for the lack of development, or outright rejection by your software developer. The Fediseer already provides endorsement functionality along with a full REST API, so you can already implement this Feeler functionality by a few simple scripts!
The “protected boost” mode would require mastodon developers to do some work of course, as that relies in the software internals which cannot be easily hacked by server admins. But this too can potentially just be a patch to the software that only Feeler-admins would need to run.
The best part of this approach is that it doesn’t require any communication whatsoever. All it needs is for the “Feeler” admins to be actively curating their endorsements (either on the Fediseer, or locally if it’s ever added to the SW). Then all allow-list server has to do is choose which Feelers they trust and “subscribe” to their endorsement list for their own allow-list. And of course, they can synchronize or expand their allow-list further as they wish. This approach naturally makes the distributed nature of the Fediverse into a strength, instead of a weakness!
Now personally, I’m a big proponent of the “human touch” in social networks, so I feel that endorsement lists should be a manual mechanism. But if you want to take this to the next level, you could also easily set up a mechanism where newly discovered instances would automatically pass into your endorsement list after X weeks/months of interaction with your user without reports and X-amount of likes or whatever. Assuming admins on-point, this could make widely Feeler servers as a trusted gateway into a well protected space on the fedi, where bad actors would find it extraordinarily difficult to infiltrate, regardless of how many instances they spawn. And it this network would still keep increasing each reach constantly, without adding an extraordinary amount of load to its admins.
Barring the “protected boost” mode, this concept is already possible through the Fediseer. The scripts to do this work already exist as well. All it requires is for people to attempt to use it and see how it functions!
Do point out pitfalls you foresee in this approach and we can discuss how to potentially address them.
I noticed recently that a few instances are just issuing counter-censures on the Fediseer just to be able to reply to the censures they received from others. While I get the need to say your piece, I didn’t like this utilization. So I wanted to provide an official way for instances to reply to censures and hesitations they received.
So now we’ve deployed Rebuttals. A Rebuttal is a “reply” to a censure or hesitation from another instance. If you have received both, the same rebuttal applies. This is set up this way so that rebuttals are not tied to any specific censure/hesitation and therefore being deleted when those are. If someone deletes and re-adds their censure against your instance, the same rebuttal will re-appear.
As always, remember there’s no hate speech allowed on the Fediseer, so make sure your rebuttals stay cool.
Also keep in mind the Fediseer is not a forum. There won’t be multi-threaded discussions going on. The expectation is that you can use the Rebuttals to explain why a censure is bogus and whatnot. Not to maintain flamewars.
I know there’s plenty of beefs on the Fediverse. I’m hoping with this feature won’t become fuel for them, but rather a way for everyone to feel they have a say in a neutral ground. I hope this can serve as a de-escalation as well. Sometimes an instance might receive a hesitation or censure from someone they don’t dislike, due to a misunderstanding. This will allow them to try and counter that, without having to counter-censure.
Let me know what you think in the comments below, by replying to this post on mastodon, or in the lemmy community.
Btw, since I have you here, did you know that you can support the hosting and development of the Fediseer? Currently I’m paying the hosting costs out of pocket. It’s not a lot but it would be nice if the infrastructure costs were self-sustaining. So if you find value in this service, feel free to throw some money at the development team.
One can now request all endorsements from multiple domains:
This allows instances to quickly discover a “list of friends” based on other instances. Use cases for this might include scripts which auto-approve comments in moderation, or automatically update a fediverse instance’s whitelist based on common endorsements.
Censures
The current fediseer guarantees are meant to apply only to consideration of spam. As such we do not have a way to mark instance that many would consider terrible in all other ways except spam (e.g. pro-nazi instance, or an instance allowing loli content) as such.
To solve this a new feature has been added: Censures
An instance can now apply a censure to any other instance domain (whether it’s guaranteed already or not) for any reason. This extreme disapproval can come from any subjective reason, but like endorsements it doesn’t, by itself, have any mechanical impact.
In fact, because endorsements and censures are explicitly subjective, I have taken the decision to not display censure counts on instance details to avoid people using them for “objectively” rating instances which is not their intended purpose. This is because one’s instance could easily be censured by a lot of, say, fascist instances, but this should have no overall impact on how non-fascists percive that instance.
Instead, one can see combined censure lists from multiple instances, like one can see combined endorsements. You simply pass a comma-separated list of domains to the /api/v1/censures_given endpoint and you get a list of all the instances they have censured collectively.
This endpoint can then be consumed to make collective blocklists among instances that trust each other, without one having to manually discover and parse different instance federation blocklists all the time.
Likewise, by not being explicitly tied to a blocklist, the censure list could also be used to enforce a softer approach. For example by having an auto-moderator script which flags comments from censured instances for manual review, etc. This could allow an instance to retain a less-restrictive blocklist, but still allow for more rapid response to users coming from potentially problematic instances.
As always, the point of the fediseer is to allow a way to provide the information easily, rather than to dictate how to use it. I excited to see in which ways people will utilize the new abilities.
Yesterday I read the excellent article by Cory Doctorow: Let the Platforms Burn and this particular anecdote
The thing is, network effects are a double-edged sword. People join a service to be with the people they care about. But when the people they care about start to leave, everyone rushes for the exits. Here’s danah boyd, describing the last days of Myspace:
If a central node in a network disappeared and went somewhere else (like from MySpace to Facebook), that person could pull some portion of their connections with them to a new site. However, if the accounts on the site that drew emotional intensity stopped doing so, people stopped engaging as much. Watching Friendster come undone, I started to think that the fading of emotionally sticky nodes was even more problematic than the disappearance of segments of the graph.
With MySpace, I was trying to identify the point where I thought the site was going to unravel. When I started seeing the disappearance of emotionally sticky nodes, I reached out to members of the MySpace team to share my concerns and they told me that their numbers looked fine. Active uniques were high, the amount of time people spent on the site was continuing to grow, and new accounts were being created at a rate faster than accounts were being closed. I shook my head; I didn’t think that was enough. A few months later, the site started to unravel.
This is exactly what is happening to Reddit currently. The most passionate contributors, the most tech-literate users, and the integrators who make all the free tools in the ecosystem around reddit which makes that service much more valuable have left and will never look back.
From the dashboards of u/spez however, things might looks great. Better even! As the drama around their decision making certainly caused a lot more posts and interactions, and the loss of the 3rd party apps drove at least a few users to the official applications.
But this is an illusion. Like MySpace before them, the metric might look good, but the soul of the site has been lost. It’s not easy to explain but since I’ve started using Lemmy full-time, I’ve seen the improvement in engagement and quality in real time. half a month ago, posts could barely pass 2 digits, now they regularly break 3 and sometimes 4 digits. And the quality of the discussions is a pleasure to go through.
I said it before, but reddit was never a particularly good site. Their saving grace was the openness of their API and their hands-off approach to communities. The two things they just destroyed. It’s those 3rd party tools and communities that made reddit like it is. As as the ecosystem around reddit sputters and dies, the one around the Threadiverse is progressing in an astonishing rate.
Not only are the integrators coming from reddit aware what kind of bots and tools are going to be very useful, but a lot of those tools are shut off from reddit and switched to the lemmy API instead, explicitly cannibalizing the quality of the reddit experience. And due to the completely open API of the Threadiverse, those tools now get access to unparalleled access and power.
Sure if you visit reddit currently, you’ll see people talking and voting, but as someone who’s been there from the start, the quality has fallen off a hill and is reaching terminal velocity. But it feels like one’s still flying!
Not just the quality of the posts where only the most superficial meme stuff can rise to the top, not just the quality of the discussion, but even mere vibe of the discussions is just lost.
There’s now significant bitterness and hostility, especially as the mods who were responsible for maintaining the quality, have gone or are being hands off or just don’t have the tools needed to keep up. I’ve heard from multiple people who are leaving even while they were not originally planning to, because the people left over in reddit are just so toxic.
This is a very vicious cycle which will accelerate the demise of that site even further.
A house fire can go from a spark to a raging inferno in less than a minute. The flames consuming reddit are just now climbing up the curtains and it still appears manageable, but it’s already too late. Reddit has reached terminal enshittification and the only thing left for it to do, is die.
