I'm not a game dev so please forgive me if this is the wrong place for this type of question but I'm looking for some resources to try and understand why games take so long to compile.

For context, I've worked with former game devs who've mentioned that builds can take anywhere from 4 to 6 hours to complete - even with a distributed architecture - depending on the hardware. That shit blew my mind. They said it has something to do with compiling shader permutations but didn't go into anyore detail. That said, I have a very primitive understanding of what shaders are but I mostly work with infrastructure and optimizing build systems.

Like I said, I'm not a game dev, im just curious. I appreciate any insight or resources you throw my way. Thanks!

I hate how you need a phone number for everything these days... I'm looking for recommendations on an app or service for temporary phone numbers.

I know that "free" services exist for what I'm asking for but I don't like the idea of receiving potentially sensitive info in a place that anyone can access.

Ideally, something like "simple login" would be perfect. Any recommendations would be greatly appreciated!

Just getting started with self hosting. I was wondering if anyone had experience with Cloudflare Tunnels for exposing their services to the internet. I like the simplicity and security it offers but don't love the idea of using Cloudflare. Like, I'm self hosting for a reason lol. Any tips would be greatly appreciated!

For context, I'm running all of my services in a very small k8s cluster and my priorities are mostly security then maintainability. Thanks yall!

EDIT: yall are great! Thank you so much for the replies. I'm going try my luck with pangolin but its good to know I have options.

Im very new to 3d printing and this is my first time using anything other than pla. So far all of my prints are lifting off the bed at the corners. They start off looking beautiful. No stringing, great adhesion, etc. But after a few layers, they start to come off. Especially on larger prints.

Heres my setup:

• Ender 3 pro with skr mini e3 v2
• Creality Ender 3 glass bed upgrade
• Bed temp: 90C
• Extruder temp: 240C
• Nozzle diameter: .4
• Layer height: .2
• First layer: .45
• Speed: 60mm/s
• Slicer: Silc3r

I realize that asking this question is like asking WebMD to dianose my sniffles, cause it can literally be anything, but Im hoping someone with more experience can give me some pointers on what works for them. Thanks yall!

Update: First of all, thank you all so much for the kick ass suggestions! I really appreciate all of your replies. Since pretty much everyone recommended it, I went ahead and got a textured spring steel PEI plate and holy shit, it didn't disappoint. Adhesion has been fantastic. I also ended up lowering my bed temp down to 75 from 90 and pushing my hotend temp to 245 for the first layer, then back to 240. I got an enclosure to help keep the plate clean but I also stocked up on some blue dawn dish soap. I still have a little more trial and error with print speed and cooling but I'm literally getting the best prints I've ever gotten thanks to all of your suggestions. Yall are awesome and I'm really glad I posted here.
