Please remember that this is a friendly event, but we are all folding away for Science, AND GLORY! 
 
Thank you to all who are involved and who make this worth while every year.
 
Remember we are a team first and individuals second, so give thanks where thanks is due and hit that reaction button when someone helps you out.
 
Be wary of the minimum participation requirements this year.
 
 
Happy folding,

I'm not going to write anything here as you can see the details of the ranks on the link. My partner is staying over tonight and I have to be up in 6 hours.

It goes without saying that we are thin on the ground, but no matter, we will push on.
 
This will be a short post, mostly cause Fridays is my drinking call on discord! 
 
In first place we have Miker07 with 26.13 million points, tailing behind him with "only" 19.6 million points we have Justaphf, third place is occupied by Pezui with 13.01 million points. That is the top three and as we can see even with the Den-Fi menace missing we can see some strong numbers. Fourth place is taken by Ir8munk33 with a fairly decent 10.74 million points and fifth place is RollinLower with 8.09 million points.

Well here we are, at the end of our little five day sprint. It went by super fast and half the team ended up unavailable due to illness or work.  So massive, MASSIVE Thanks to @cbigfootWho honestly did 70% of the work on this one. Really, He carried the event this time around and deserves all the thanks we can give him. 
 
I'm not going to talk too much hear as this is a low effort mini event but can we all just appreciate that somehow, Den-Fi managed to win again... no-one could have seen this coming... honestly... I'm sure he is as surprised as the rest of us. /s 
 
You have seven days to claim the prizes from this event. To claim the prize you need to DM me. It's that simple. They will now be rerolled if you don't claim they will simply be added to the community pool.

The ever present and benevolent Den-fi continues his reign of chaos with 1,148.52 million points, producing over ten percent of the entire events output today is certainly looking undefeatable by this point in the event. Macaw2000 has made himself comfortable in second place with a very admirable 742.45 million points, and rodarkone is in third place with 689.07 million points. Unilevers is still sitting in fourth with 521.16 million points, miker07 is in fifth place with 475.67 million points, Gorgon takes sixth place with 461.21 million point. Then we see a large drop in the production levels, Shlouski takes 7th place with 371.89 million points, _Rlocke is on 8th place with 362.25 million points and LAR_Systems, the master of the great folding database takes 9th place with 291.64 million points. Finally we have justaphf in the gatehouse with 287.81 million points.

Timeline of the outage: (times in UTC)
Starting at 02:03 on Saturday, requests started intermittently returning error 502, and many of the requests that were served successfully were significantly slower than normal At 05:59, most of the services on the server crashed. All subsequent requests were served by Cloudflare with error code 502 At about 11:00, I came online and attempted to diagnose the problem. Due to the previous failures I was unable to access the server, so all I was able to do was route traffic to an offline page At 16:35, with extra help, the server was forcibly restarted At 16:43 the server seemed to have come up successfully, so we enabled traffic and monitored the status By 16:53 it was clear that performance very poor and a significant fraction of the requests were resulting in error 502 (which means in this case that the server was already processing too many requests, so where were no workers available), so we disabled traffic again to investigate the situation further At 17:36, there was nothing clearly wrong so we tried enabling traffic again At 17:39 the performance was significantly regressing again so the site was turned offline again At 18:00 we ordered a new server At 18:35 the server was ready to be set up with all of the forum-related things, and for the data to be migrated to it At 21:28, the new server was fully set up and the forum was turned back online  
What were the symptoms?
IOWait accounted for the majority of CPU time, but IO utilisation was relatively normal In the syslog we were seeing a number of IO timeouts for the primary drive Prior to rebooting, the limited errors that we could see indicated that there had been disk corruption  
What was the root cause?
Although we aren't 100% sure, we think it's fairly likely that one of the two RAID 1 disks that form the primary disk had failed, and the poor performance was a consequence of trying to rebuild the array.
 
Why replace the server rather than the disk?
There were already plans to replace the server, this failure just accelerated them. We were also of the opinion that having the disk replaced and getting the array rebuilt would likely not end up being faster, especially as we did not have sufficient information to pinpoint the failure.

The LTT forum is built on Invision Community (previously known as IPS and IPB), an off-the-shelf forum software. The majority of the code that powers the forum is theirs, and the technologies that we can use are largely constrained by what Invision Community supports.
 
The backend is written entirely in PHP, using a custom framework built specially for Invision Community. Some type annotations have been introduced into the codebase recently, but most of the code was written before PHP supported types and is therefore untyped (this applies to both IC's code and our custom additions). For a sense of scale, there are over 450,000 lines of PHP in Invision Community, and about 12,000 lines of LTT-specific PHP.
 
Data is stored in MySQL, Elasticsearch and Redis. MySQL is the source of truth for all of the data in the system, and interaction with it from the backend code use Active Records. User content is duplicated into Elasticsearch to power the search functionality, as well as activity feeds and content feeds on user profiles (everywhere that combines content of multiple different types into one view). Redis is just used as a cache for frequently accessed or expensive values.
 
Requests are handled using NGINX, and your requests also pass through Cloudflare before getting there to the server.
 
All of the backend services are hosted on one server, with a 16 core EPYC processor. On the server, we're running CentOS 8.
 
For the frontend, all of the HTML rendering is performed on the server side, using a custom HTML template syntax that works similarly to mustache (although with considerably less polish). Writing this code is virtually identical to writing raw HTML, except that you can use variables, use loops, and import other templates. Invision Community also has its own front end CSS framework, which generally works well to minimise the specific CSS required for each new feature.
 
Continuing with the trend, there is also a custom Javascript framework for attaching controllers to elements and for declaring and using UI widgets. The framework is built for ES5 + jQuery; while it is possible to use ES6+ features in custom code, there is rarely enough that needs doing with custom code to be able to make use of much.
 
We can easily edit the PHP, HTML and CSS provided by Invision Community, both using their hook system and by directly modifying code on our fork of the code, but the Javascript framework is generally not editable because it doesn't provide a generally useable hooking mechanism and the code is stored in the database rather than in files. This means that custom javascript is generally limited to only the small amount needed to support new functionality; accordingly, we only have about 400 lines of LTT-specific JS.
 
I've also built a couple of GitHub actions in Typescript to automate some boring tasks, such as updating the repo with the latest version of Invision Community.

Hey there,

Politics
Yep. Trump ordered police to use tear gas on peaceful (very harmful) to clear way for him for his photo-op (a Bishop said it was an abuse of the Bible), which resulted in violence instead of peace so tension is high.
 
The protests happened after a policeman suffocated a black George Floyd for no reason, and then lied about it in the report.

AMD Ryzen on Smartphones?? Leak suggests that AMD is working on a SoC to compete against Qualcomm, and it has impressive specs.
Everyone wants to be a hacker with 5-year high in Google Search terms related to "Hacker course".
