I am a scientist who has semi-frequently written code in C (and other compiled languages like Fortran). When it comes time to compile, I typically tape together a Makefile from past projects and hope for the best, but even then I spend more time than I'd like to admit trying to figure out why my project is not being compiled or linked correctly. I've had a hard time finding any resources that aren't extremely surface level, or else are not behind some type of paywall. Can anyone recommend me some reading so that I can confidently write Makefiles and compile programs and actually understand what the different flags and commands are doing? I don't need extreme "under the hood" information as I don't intend to do things like write my own compiler, I just want to understand the process a little better. Help a scientist out!

I'm trying to go beyond Reddit and Tildes when it comes to some particular interests. I dislike Federated websites due to their usability issues, but I also get the impression that they try to replicate or improve on Twitter. I never used or cared for Twitter in the first place.

I found TrekBBS which looks great, but I was wondering about similar forums for my other interests, such as science fiction literature, classic movies, etc.

So I am curious to know about everyone's favorite old-school forums that are still active and cool!

The websites are not required to be actually old, as long as they work similarly to traditional internet forums.

My iPhone 14 Pro has been at 84% battery health for almost a year now. Anecdotally the battery lasts significantly less time than it did previously, even when it was already at 84% health. I think it may just be a stale calculation, and my actual battery health is significantly lower. If I can get it to show as less than 80%, I can get AppleCare to replace it. Does anyone here know how to get the iPhone to recalculate this value?

I have Coconut batter on the Mac, and it can check the battery health for an iPhone attached with a cable. It uses a different formula, so it gives me a health of 87%. However it also shows history for when I have run it in the past, and when I tested it almost 100 charge cycles ago, it also read 87%. I don't know how any battery can go almost 100 charge cycles with zero degradation (537 to 617 cycles, so it's not like it's a fresh battery).

What have you been doing lately for your own fitness? Try out any new programs or exercises? Have any questions for others about your training? Want to vent about poor behavior in the gym? Started a new diet or have a new recipe you want to share? Anything else health and wellness related?

I currently have a Corsair Dark Core Pro SE that I like a lot. My scroll wheel is messed up though. I am kind of in the trenches (who isn't these days), and am looking for some good old retail therapy.
My big ticket items:

• works well on linux (openRGB if possible)
• has forward and back thumb buttons
• scroll wheel works (lol)
• has nice support for pinky (I really like this feature on my current mouse)(as I have big hands)

I am not opposed to just buying another of my current mouse, I can't tell if there is anything really comparable. I also don't really understand/care for my mouse being lightweight.

Deep cut question though is if anyone has any experience with trackballs, I kind of want to try it out but ultimately I don't really know what I am doing. I really just use my computer casually, and I don't play any competitive games just casual.

Any recs? Thanks, happy to answer any questions too.

The time loop topic has a few entries of media where the time loop is a twist/spoiler, and made me think of how hard it is to recommend books/media where the reveal is part of what makes it impactful.

Two I can think of off the top of my head are

• The Girl with all the Gifts by Mike Carey

• We are all completely beside ourselves by Karen Joy Fowler

Very different genres and topics and I can't at all think of how to describe either one without spoiling it.

As part of a weekly series, these topics are a place for users to casually discuss the things they did — or didn't do — during their week. Did you accomplish any goals? Suffer a failure? Do nothing at all? Tell us about it!
