FAF DevOps Councilor since 2018 FAF developer since 2016 FAF member since 2013
(version from 07.07.2021)
This code of conduct applies to all spaces managed by the FAForever project, including IRC, Forum, Discord, Zulip, issue trackers, wikis, blogs, Twitter, YouTube, Twitch, and any other communication channel used by our communities.
We expect this code of conduct to be honored by everyone who participates in the FAForever community formally or informally, or claims any affiliation with the Association, in any FAF-related activities and especially when representing FAF, in any role.
This code is not exhaustive or complete. It serves to distill our common understanding of a collaborative, shared environment and goals. We expect it to be followed in spirit as much as in the letter, so that it can enrich all of us and the technical communities in which we participate.
The Code of Conduct may be supplemented by further rules specifying desired and undesired behaviour in certain areas.
We strive to:
Be open. We invite anyone to participate in our community. We preferably use public methods of communication for project-related messages, unless discussing something sensitive. This applies to messages for help or project-related support, too; not only is a public support request much more likely to result in an answer to a question, it also makes sure that any inadvertent mistakes made by people answering will be more easily detected and corrected.
Be empathetic*, welcoming, friendly, and patient. We work together to resolve conflict, assume good intentions, and do our best to act in an empathetic fashion. We may all experience some frustration from time to time, but we do not allow frustration to turn into a personal attack. A community where people feel uncomfortable or threatened is not a productive one. We should be respectful when dealing with other community members as well as with people outside our community.
Be collaborative. Our work will be used by other people, and in turn we will depend on the work of others. When we make something for the benefit of the project, we are willing to explain to others how it works, so that they can build on the work to make it even better. Any decision we make will affect users and colleagues, and we take those consequences seriously when making decisions.
Be inquisitive. Nobody knows everything! Asking questions early avoids many problems later, so questions are encouraged, though they may be directed to the appropriate forum. Those who are asked should be responsive and helpful, within the context of our shared goal of improving the FAForever project.
Be careful in the words that we choose. Whether we are participating as professionals or volunteers, we value professionalism in all interactions, and take responsibility for our own speech. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behaviour is not acceptable. This includes, but is not limited to:
Be concise. Keep in mind that what you write once will be read by hundreds of persons. Writing a short message means people can understand the conversation as efficiently as possible. Short messages should always strive to be empathetic, welcoming, friendly and patient. When a long explanation is necessary, consider adding a summary. Try to bring new ideas to a conversation so that each message adds something unique to the thread, keeping in mind that the rest of the thread still contains the other messages with arguments that have already been made. Try to stay on topic, especially in discussions that are already fairly large.
Step down considerately. Members of every project come and go. When somebody leaves or disengages from the project they should tell people they are leaving and take the proper steps to ensure that others can pick up where they left off. In doing so, they should remain respectful of those who continue to participate in the project and should not misrepresent the project's goals or achievements. Likewise, community members should respect any individual's choice to leave the project.
FAForever welcomes and encourages participation by everyone. We are committed to being a community that everyone feels good about joining. Although we may not be able to satisfy everyone, we will always work to treat everyone well.
No matter how you identify yourself or how others perceive you: we welcome you. Though no list can hope to be comprehensive, we explicitly honour diversity in: age, culture, ethnicity, genotype, gender identity or expression, language, national origin, neurotype, phenotype, political beliefs, profession, race, religion, sexual orientation, socioeconomic status, subculture and technical ability.
Though we welcome people fluent in all languages, all official FAForever communication is conducted in English. Translations may be provided, but in case of contradictory wording, the English version takes precedence.
Standards for behaviour in the FAForever community are detailed in the Code of Conduct above. We expect participants in our community to meet these standards in all their interactions and to help others to do so as well.
While this code of conduct should be adhered to by community members, we recognize that sometimes people may have a bad day, or be unaware of some of the guidelines in this code of conduct. If you believe someone is violating this code of conduct, you may reply to them and point out this code of conduct. Such messages may be in public or in private, whatever is most appropriate. Assume good faith; it is more likely that participants are unaware of their bad behaviour than that they intentionally try to degrade the quality of the discussion. Should there be difficulties in dealing with the situation, you may report your compliance issues in confidence to either:
If the violation is in documentation or code, for example inappropriate pronoun usage or word choice within official documentation, we ask that people report these privately to the project maintainers or to the DevOps Team Lead (Brutus5000, brutus5000 at faforever dot com).
* This Code defines empathy as "a vicarious participation in the emotions, ideas, or opinions of others; the ability to imagine oneself in the condition or predicament of another." Empathetic is the adjectival form of empathy.
This statement was shamelessly copied and modified from the Apache Software Foundation Code Of Conduct and it’s honoured predecessors.
Sometimes people ask us: Can't you just stop changing things and leave FAF as it is? The answer is no, if we do that FAF will eventually die. And today I'd like to explain why.
Do you still use Windows XP? According to some FAF users the best operating system ever. Or Winamp? Or Netscape Navigator? Or a device with Android 2.3?
Probably not. And with good reason: Software gets old and breaks. Maybe the installation fails, maybe it throws weird errors, maybe it's unusable now because it was build for tiny screen resolutions, maybe it depends on an internet service that no longer exists. There are all sorts of reasons that software breaks.
But what is the cause? And what does that mean for FAF?
People are lazy and want to make their lives easier. When the first computers were produced, they could only be programmed in machine language (assembler). In the 80s and 90s some very successful games like Transport Tycoon were written in assembler. This is still possible, but hardly anyone does it anymore. Effort and complexity are high and it works only on the processor whose dialect you program.
Nowadays we write and develop software in a high level language like C++, Java or Python. Some smart people then came up with the idea that it might not make much sense to program the same thing over and over again in every application: Opening files, loading data from the internet or playing music on the speakers. The idea of the library was born. In software development, a library is a collection of functions in code that any other developer can use without knowing the content in detail.
These libraries have yet another name, which sheds more light on the crux of the matter: dependencies. As soon as I as a developer use a library, my program is dependent on this library. Because without the library I cannot build and start my application. In times of the internet this is not a problem, because nothing gets lost. But the problem is a different one, we will get to that now.
Even if it sounds banal, every piece of software (including the libraries mentioned) goes through a life cycle. At the very beginning, the software is still very unstable and has few features. Often one speaks also of alpha and beta versions. This is not relevant for us, because we do not use them in FAF.
After that a software matures. More features. More people start using them. What happens? More bugs are found! Sometimes they are small, e.g. a wrong calculation, but sometimes they are big or security related problems. Those that crash your computer or allow malicious attackers to gain full access to the computer they are running on. Both on the FAF Server and on your computer at home a nightmare. So such bugs have to be fixed. And now?
Scenario A: A new release is built. But: A new release of a dependency alone does not solve any problems. It must also be used in the applications that build on it! This means that all "upstream" projects based on it must also build a new release. And now imagine you use library X, which uses library Y, which in turn uses library Z. This may take some time. And 3 layers of libraries are still few. Many complex projects have dependencies up to 10 levels deep or more.
Scenario B: There is no new release.
Finally, all commercial software will end up in scenario B at the end of its life cycle. And in most cases open source software also builds on top commercial software directly or indirectly.
Just a few examples:
What happens at the end of the lifecycle? For a short period of time, probably nothing. But at some point shit hits the fan. Real world examples:
FAF has hundreds of dependencies. Some are managed by other organisations (e.g. the Spring framework for Java handles literally thousands of dependencies), but most are managed by ourselves.
A few examples that have cost us a lot of effort:
Many of these changes required larger changes in the software codebases and also impacted the behavior of code. As source of new bugs to arise.
If we would freeze time and nothing would change, then all this would be no problem. But the software environment changes, whether we as developers want it to or not. You as a user install a new Windows, you download updates, you buy new computers, there is no way (and no reason) for us to prevent this.
And we must and want FAF to run on modern computers. And of course we want to make bug fixes from our dependencies available to you. So we need to adapt. FAF is alive. And life is change. But unfortunately in software change also brings new errors.
Everytime we upgrade a dependency we might introduce new bugs. And since we're not a million dollar company, we have no QA team to find this bugs before shipping.
The ICE adapter disagrees.
Hello everybody,
we apologize for the technical issues in the last 2 days. Nevertheless the vote ended and Morax is the official winner of the election.
We thank FtxCommando for his service in the last 2 years.
The mode of vote was instant run off. So every round we eliminate the candidate with the least votes and transfer his votes to whatever the voter has defined as the next fallback vote. Since we only had 3 candidates that makes it fairly easy to lookup.
Results of the 1st iteration (primary votes):
FtXCommando is last and his 175 votes are transferred to:
This gives us results of the 2nd iteration:
As it's only 2 candidates left, the one with the majority wins. In this case it's Morax.
Also people wanted to know when was voted and if we can shorten future voting periods. Here is some data:
Today two thousand players encountered once again how fragile our whole server setup sometimes is and how an unlikely chain of events can cause major issues. In this talk I want to shed some light on how the chain started moving.
We are currently investigating CPU load issues in the client which we could track down to updates of the chat user list in #aeolus. If you open the chat tab you see a partial list of users, as not the whole list fits to the screen. We are using a ListView component from our UI framework for this. Each row or ListItem (a user or a group name) is one element in this list view. However, it would be very memory hungry, if the application would render each chat user's list item (~2000 on peak times) if you can only see a few dozen of them. Therefore the list view component only holds a pool of list items that you can actually see and re-uses / redraws / repopulates them as the list changes. When profiling the application I could observe hundreds of thousands of updates to the list over a period of 10-15 minutes with about 2.000 users logged in to the chat. Something was causing massive changes to the user list and we couldn't find a reason.
ListView
ListItem
On a different topic we noticed an increasing number of errors when trying to login to the IRC on peak times for no obvious reason as well. Sometimes it took multiple minutes to login.
But then somebody using a regular IRC client looked into the logs and found an interesting thing: a lot of people were logging in and out in a very short period with the quit message "Max SendQ exceeded". A little bit of googling revealed, that this error message was thrown, when the IRC server sends data to the client, and the client doesn't load it fast enough.
Using the incredibly long chat log history of our moderators we were able to track down these errors to their first occurences to October 2019 when we roughly breached 1900 users online at once. Since then FAF has been growing (up to 2200 users online at peak) and so grew the problem as well.
So there is a coincidence between the SendQ exceeded error and the amount of relogin/logouts. Now we tried to connect the dots:
So the idea was: If we could solve the IRC error, we might solve / reduce the users CPU load. A potential solution was to increase the buffer size before the server sends the error message.
The situation was perfect: 2000 users online. A configuration change. All users would automatically reconnect. We could live-test if the change would make the server go away or persist.
So we flipped the switch and restarted the IRC server.
We could observe the IRC numbers rising up from 0 to 1400 and then it drastically stopped. 600 users lost. What happened?
We expected the IRC reconnect to be simple and smooth. But when did anything ever went smooth? A look into the server console showed all cores at 100% load, most utilization by the API and our MySQL database. WTF happened?
The FAF client has a few bad habits. One of them is, that it downloads information about all clans of all people online in the chat. This is a simplified approach to reduce some complexity.
Since we only have a few dozen active clans, that would only be a few dozen simple calls which would/should be in cache already. Or so we thought.
As it turns out, the caching didn't work as intended. The idea behind the caching is the following: You want to lookup a clan XYZ. First you look into the cache, and if you don't find it here, you ask our API. Asking the API does take a few dozen milliseconds. But what happens, if you have 10 players from the same clan? You should look it up in the cache, and if you don't find it there, you would query it once, right? Well that's what we expected. But since the first API lookup wasn't finished when looking up the clan for 2nd to 10th time, each of these lookups would also ask the API.
Now imagine 2000 users querying the clans for every player with a clan tag (~200?). Boom. Our API and our database are not meant to handle such workloads. It didn't crash, but it slowed down. And it took so much CPU while doing this, that there wasn't much CPU left for the other services. It took the server roundabout 20 minutes to serve all requests and go back to normal.
Once we spotted that bug, it was an easy fix. As it turns out we just needed a sync=true to particular cases. Problem solved. Why oh why is this not the default? Well, as it turns out this option was added in a later version of our Spring framework and due to backwards compatibility it will always be an opt-in option. Ouchy.
sync=true
We saw it again: IRC sucks (well we all knew that before right?). But it seems like the IRC configuration change fixed the SendQ exceeded error. Yay, we actually might reduce the CPU usage for our players. Also we now know that synchronized caching should be the default, at least in the FAF client Unfortunately it was revealed again that the FAF api can't handle ultra-high workloads. Unfortunately limiting the amount of available CPUs in Docker does not work in out setup. Further solutions need to be evaluated (e.g. circuit breakers).
So now we know that restarting the IRC server can be a dangerous thing. So would I do it again? Hell yes. I know it sucks for the playerbase if the server is having massive lags due to running into CPU limit. But today we learned so much about what our software architecture is capable and where we have weaknesses.
We can use this to improve it. And we need to. FAF is growing more than I've ever expected. In the last 12 months our average-online-playerbase grew by ~300 users with the latest peak being 2200 users. When we moved to the new server beginning of the year I thought that our new server can handle around 3000 users, but as it turns out there is more to do.
I locked this topic (not moderators), because the user @Hashbrowns69 is a fake account that was just created today in order to perform some trolling.
However to people reading this.
I'd like to remind you that we are all working on our free time here. I have a full time job, a little son, a server to run and an association to setup.
Yes, I did not actively stop this nonsense (question is if I could), but I would like to remind you that apart from some drama nothing really happened now.
The server is running, the client receives updates, tournaments are still happening. Every organisation can have issues and yes this time it went public. That's sad but we're also all human.
FAF won't die just because there is some drama going on. There has been drama in the past, you just didn't notice.
Many of you won't remember it, but the amount of posts in this forum and the feedback we collected showed us: the onboarding process along with the registration page is a horror for new users (especially non-english native speakers).
Together with our fellow community member Terrorblade, who is a working expert on customer journeys, we worked out weaknesses in the current process and ways to fix them.
Here are few things we are doing horribly wrong:
Due to the Steam link process and the required client download the FAF onboarding process is much more complicated than the that of other websites. We even modelled a perfect workflow, but that's beyond the scope of the current work. Nevertheless for the brave peopel here I'd like to share it with you, without further explanation: 
In the last weeks I had the opportunity in my job to learn frontend development with Angular (and yet more trainings are to come). In order to train my newly gathered skills, I gave it a try. Unfortunately what I still don't have are skills for designing shit with CSS and colors.
All screenshots are representing work in progress:
Failed registration: As long as you didn't fix all issues and selected all checkboxes you can't click the button. The user lookup is done with a 1 second delay
You can dynamically switch the language. Currently I'm only populating english and german. The biggest need however would be russian.
Once you successfully registered we now (and only then) tell you, that you need to click on the email link:
Nevertheless, users are capable of switching between the steps to see whats ahead and what to wait for:
But using the activation url it looks simpler:
So after a successfull activation we can move on:
The Steam linking page needs some more info why this is required I guess:
The steam login itself is not interesting here, so I skip it. After a successfull login we get this:
And the FAF CLient Setup page is yet missing content completely. Not sure if we want to add screenshot per language, that sounds a bit too much work...
So far I have only shown the "happy path". The most important pain point for users is when the Steam linking doesn't work. We need to be able to distinguish between "You don't own the game" and "Your profile seems to be not public", but this needs some API changes as well.
I hope this change will reduce the amount of people we loose on the way to FAF. But it's still a long way and it might need much more time invested. So far I spent around 20 hours to reach this state (yet I'm facing many beginner problems as this is my first bigger Angular project, so it's a lot of basic learning time included).
Maybe I'll do some more Twitch streams and now the 5 people who saw my last (and first) stream know what they actually saw
Please share ideas and feedback guys!
It's quite some time since my last blog post and therefore I want to give you a little update on what has happened since then.
A lot of issues cascaded and blocked each other, so in many terms it didn't really feel like much progress, because nothing got really finished. But the story behind it might be interesting for you nevertheless.
So here comes the probably longest issue and failure compilation of FAF we ever had (and it's just the stuff I remember)
Travis CI terminating services Travis CI is a "continuous integration" platform that we use in almost every Github repository to run automated tests and to build releases.
Unfortunately it looks like Travis CI is in financial trouble and they massively reduced the capacities for open source projects. Out of a sudden almost every repository needed to wait half a day or longer for a single test run or building a release, and in many cases even those failed.
As a solution we migrated most of the core repositories to Github Actions, which is not only faster but nicer to use in many cases. But depending on the CI pipeline complexity that was an effort of multiple evenings until everything was sorted out.
There are still repositories waiting to be migrated
GoLive of the matchmaker So shortly before Christmas we reached the final phase of the matchmaker. In the hurry a few points were overlooked which caused some troubles:
Moving to MariaDB The MySQL issue showed us once again that we want to move to a new database version. The current MySQL 5.7 is quite old. This discussion is not new, actually it's already almost 2 years old but got deferred because there was no real pressure (and we couldn't really agree whether to go to MySQL 8 or MariaDB 10.x which are both compatible with MySQL 5.7 but incompatible with each other).
The server downtime caused by the suboptimal query as described above made me reconsider. We had multiple issues with MySQLs shitty way of doing a specific type of join (nested loops). So we tested this with MySQL 8 and MariaDB 10.5 on a copy of the production database.
There was a simple query that took 1min 25s (utilising the whole PC). MySQL 8 took just 5 seconds less. But MariaDB obviously fixed the underlying issues and returned a result in 1 second.
So this set the new path to migrate to MariaDB. A test migration from raw MySQL 5.7 without backup and restore ended up in a corrupted data set. So we'll need to to proper backup and restore.
Unfortunately MariaDB tripped over one of the migration files when creating the current database scheme. Therefore I tried to merge all migrations into a single database schema import (which took a few days to figure out).
Once this was done I still encountered the error with a better description just to figure out that this was due to a bug in MariaDB that was marked as fixed already but no release yet! So it had to be postponed once again...
It's finally released by now, and we'll need to restart some testing. This is probably part of the next server update.
Auto-Backups killed the server Our new server uses ZFS as file system which is very modern and powerfull. When we setup the server we thought using ZFS for the Docker (the container daemon running all apps) container volumes was a good idea. It wasn't, instead it was polluting the system with ZFS datasets for each docker container layer (there were HUNDREDS of them). Even though this caused no direct harm, it prevented us from activating auto-backups.
With the last server update we fixed this and are now back to a proper dataset list:
NAME USED AVAIL REFER MOUNTPOINT tank 888G 34.4G 3.93G legacy tank/docker 32.7G 34.4G 29.1G - tank/fafstack 160G 34.4G 158G legacy tank/mongodb 353M 34.4G 277M legacy tank/mysql 13.5G 34.4G 12.4G legacy tank/replays 677G 34.4G 677G legacy
And then we thought activating auto-backup was a good idea. But it was not. Even though using snapshots should only consume the "delta" between the current and the previous state on disk MySQL alone took ~20GB for 5 snapshots. This brought the server disk into critical area, where it started mounting parts of the file system as read only.
The solution was to remove the backup snapshots and restart the server and work on the next topic:
Replay recompression When we rented the new server in January 2020 we were thinking about how much disk space we need and what the additional cost for more storage would be. Back then we came to the conclusion that 1 TB would suffice, and once we run into problems we'd optimize the replays stored on the disk.
The replay format dates back into ancient times, where some weird decisions were made. A replay file contains of 1 lines of JSON describing the content of the replay. After the line break there is a base64 encoded deflate-compressed.
The deflate compression algorithm is ancient and very inefficient compared to modern algorithms. Base64 encoding is a way to force any kind of binary data into a representation of the ASCII character set. This might have made sense 2013 for download compatibility, but I highly doubt it. The massive disadvantage is, that base64 encoding brings an overhead of around 30%.
Improving this replay format is a topic again, that is well known and older than 2 years and always scheduled for "can be done when needed". Even though there were code changes lying around for the replay server and the java client.
The new plan is instead of zip + base64 we will compress the replay stream with the Zstandard algorithm developed by Facebook (the best compression algorithm around).
Actually the latest client release 1.4.1 added support for the new replay format, as we already saw the server disk going full (but we expected to have more time).
With the server crash due to disk space we reprioritized this issue. Now with the client release out we prepared a script to re-compress all existing replays to Zstandard (currently I'm doing some last backups, but I intend to start it tommorow). With test excerpts we could see a reduction of 40% disk space. This will free up at least 200GB on the server, making room for another 2-4 years of new replays.
Current estimation say it will take 10 days if we run it without parallelization.
The OAuth cascade of Doom In my last blog I presented a new registration page. Unfortunately when trying to finish it I hit a wall on login to our API. It took me over 2 months to figure out the whole complexity of the problem.
When we started work on the FAF API we selected OAuth2 as a standardized, mature and safe protocol for login to the web. And that is sort of still the case. Then we build a whole authorisation server into our API that takes care of the whole set of login flows. Currently we use 2 of these: If you login via the website or the forum, you get redirected to an API login page and after login redirected back. This is called the "implicit flow". The java client however uses a classic username and password approach. This is known as the "password flow".
Following standards and using well known frameworks I expected to be able to connect to the API from my registration app very easily. But it didn't work out. Today I know: This is related to the fact that the concrete OAuth2 implementation we use is customized in a non-standard way (which I never even was aware of). There is a better way of doing it now, with a new standard on top of OAuth2 called OpenID Connect.
Unfortunately our API library is deprecated and it's successor dropped support for the authorization server alltogether. Therefore a replacement was needed eventually.
I was looking into the space of cloud offerings if there are any free services that could work out for FAF. But as it turns out FAF is huuuge with it's 250.000+ playerbase. Running this as a service in the cloud would cost us hundreds, maybe thousands of Euros per month. (Currently we spend just ~80€ on the prod server total cost)
So we needed something self hosted. 2 candidates were evaluated: RedHat Keycloak and Ory Hydra.
RedHat Keycloak is the more mature product so I evaluated this first. After a week of experiments, it turned out to be completely unsuitable for FAF as it is built for enterprise where you e.g. need to give your firstname and lastname and can't select a username (or even change it).
Ory Hydra on the other hand is just one tool that does OAuth2 flows and nothing else and needs to be combined with your own software. So I wrote a new one with a new fancy login and everything (that's a whole story on its own) and after 2 months and a shitton of failures mostly related to fighting http vs https in an internal network I was capable to login to the test server.
But then I was stuck because the API needs to support the old way of login and the new way of login, as the tokens look different and the cryptographical signatures are different etc.. So I wrote a compatibility layer to support both.
But now we're stuck again. Ory Hydra takes security very seriously. And due to that they refuse to implement deprecated legac OAuth flows such as "password flow", which the FAF client uses... So we need to implement a web-based login. But there is no library support out there because the open source world has moved away from desktop applications a long time ago.
So in theory we need to build a web-based login using a WebView and catch the responses to get the access tokens generated there. But on the other side we still need to login the classic way because the server still uses the old username/password to check the login itself... there are plans and suggested code changes to fix that as well but..
Summary: It's all incompatible with each other and a transitional approach seems almost impossible. We'd need a big-bang golive deprecating all older clients with the risk of nobody being able to login to FAF for quite some time.
This is hell and there is no easy way out, but there is no alternative in the long run. And we can't just wait for the next explosion to pressure us
You want to contribute to FAF but you're unsure? You think you lack the skills? Well then read on, todays blog is for you! Even though it's a story about developers, it applies to all contributors! (Also watch my YouTube tutorial on how to start contributing).
I want to tell you 2 independent stories about 2 very different developers:
I once met a Java developer at a party in his late twenties who was working in a software consultancy for a few years. From a trustworthy source I knew he was quite talented and he was very unhappy about his salary. Back then my company was looking for developers, so I approached him and asked him about his skills. So he was doing mostly Java frontend (ugh, not so modern) and regular backend stuff. I told him that my company was hiring. Of course he was interested, so I handed in his application.
I met him again before the interview and talked to him. I said "Dude, I saw in your application that you have no experience in software development in the cloud with Kubernetes and Docker and all the fancy shit. I have this open source project called FAForever. I could show it to you and explain you a lot of stuff before the interview." He declined and I asked why. "Well, I spend so much time at work, I don't want to drag it into my own personal life, but of course I will say I'm eager to learn it on the job." He was not hired.
Why am I sharing this story? First of all, I'm not criticizing here. It's an absolute fair point to strictly separate your personal life from your work life. I'm sharing this story because it shows, that not every developer has the same mindset about learning in his free time. It's also obvious that it's not the skillset alone that makes a developer suitable for FAF.
Let's take another example. A few years ago there was a dude lurking in the FAF Slack offering help. He knew FAF for quite some time as a player, but recently stumbled over the open source project. He had a vision of bringing back Galactic War, but he had only basic programming experience. But was experienced in database queries as he was working as a consultant for ERP systems. He offered some help on administrative tasks on the server, e.g. running manualy queries (a lot of work was done directly in the database back then), helping on patch days or keeping an eye on the less-important software like the website.
Over time he gained more and more responsibilities and even started more and more on development. But man, did he fuck up things. One day he wanted to backup the website before an upgrade and gzipped all files, not knowing that the gzip command deletes the files afterwards, which resulted in afew hours downtime of the website. Or when he tried to fix some server permissions and locked out the MySQL database from its own files. But he learned. And read docs. And improved stuff. Step by step. He didn't do it all on his own of course. He was mentored by one of the reigning DevOps councilors back then.
After hundreds of hours spent on writing code and scripts, analyzing bugs, dockerizing aps, migrating servers, building/replacing/configuring software he became well sufficient with the way of software development, that he applied for a software developer job. Even though he had no commercial track record, his knowledge on software development and the cloud related technologies (e.g. Docker) was good enough, that he got the job anyway. In the same year, the dude became DevOps councilor. Some of you might have figured it out already: That guy is me. Hello!
So why am I sharing "my FAF life story" with you? Because I wanna show off? Well... maybe a little bit But moooore important in my opinion there are some key learnings that I want to share with you:
I hope you didn't get the impression that you need to spend hundreds of hours to get into FAF. You don't need to, if you want to contribute in one area. And nobody expects you to.
The most important thing is, that you have fun. I have seen many people leave because they lost fun by overacting. For me it was worth it and it was fun to spend the amount of time. Since I have a kid I have to make more and more cuts in my FAF time. That's also one of the reasons why I am trying to motivate you to become the next generation of FAF developers. The one day will come when I want to pass the baton.
Small sidenote: Some people claim that FAF is just a playground for developers, so that they have some cool technology to play with for their resume, while breaking important features for the playerbase. While I can't deny that we use our result for resumes (well I wouldn't have gotten job without it), I can assure you, that we do no play around in terms of "resume driven development".
This forum is the replacement for the old phpBB one. You probably have a lot of question, so we try to answer some of them already:
We now feature a single sign login bound to your FAF account. You do not need to create a forum account, you just login with your FAF username and password. If you change your FAF account name it will also change in this forum.
This allows to always be up to date with playernames. But even more important it is the ultimate spam prevention: a spam bot can't register to the forum without registering FAF first. This prevents all automated spam attack against the underlying software nodebb.
It has a drawback though: If you can't create or access your FAF account you can't ask for help in the forum. We kindly advise everybody to move such request to the #technical-help channel on Discord.
We dropped a lot of sub-forums that weren't really used before. We might reconsider changing more stuff based on your feedback.
We are now running on a software called NodeBB. Nodebb aims to also look nice on mobile devices. Our NodeBB uses MongoDB under the hood which is a much more suitable datastore for a forum (=> better performance)
phpBB was not fine! Let me tell you why:
This is a very good question. We will not migrate it, since this would not work out with the new forum structure and the new account linking (in the old forum we have no verified connection between a forum account and a faf account).
We want to make the forum read-only for now and maybe somebody in this community (wink, wink!) wants to write a script to turn the old forum into a static page archive.
... is debatable for sure. It took me 1 1/2 year from the first evaluation to the working solution as of now. Design was no priority topic at this point. But NodeBB offers a lot. If you are interested in helping out, please contact me.
There is a mod that stops the replay at a certain timestamp, so you go +10 and do something else for 5-10 minutes. Don't have the name though.
Micro is king. I remember Gyle casts where Zock killed 3 T1 tanks with a fucking lab. Is that cheating? No it's regular game mechanic.
Somebody once tried to train me air fights. We both took (cheated) 500 ASF and battled each other, he did good micro, I did bad micro he emerged with 400 ASFs while my ASFs were wiped out. There was not cheating in the air fight involved. We did it multiple times. It was reproducible. You don't have to like the impact that micro can have (I don't), but it's been there forever and was always a part of the game.
But will the current working authentication method work in the future (the one that the Java client 1.4.7 uses)?
No. It will be removed once all FAF services are migrated to the new version. This will probably take a very long time, but I wouldn't put any app to the old solution anymore just because it seems easier.
Of course it can. We can give it it's own OAuth client id.
You need to implement the OAuth 2.0 PKCE flow with OpenID connect (https://oauth.net/2/pkce/). It will require you to use a webview and hijack the redirect - which is what we started doing in the java client 1.5.0 RC1.
Our new OAuth service implements the auto-discovery feature (all data available at https://hydra.faforever.com/.well-known/openid-configuration).
How to do it in Python? I have no clue.
Where is the Kangaroo? Michelangelo would be disappointed.
You could also snipe the enemies energy. (Assuming the chickens are already in the enemy base)
Connectivity problems like this are beyond our control. The FAF client expects a working network connection, and if it doesn't have one it will malfunction.
That looks really cool.
Also the eastereggs. Lovely. The UEF uses power point? No wonder the almost lost the war.
