A quick look at psABI levels and compiler performance https://t.co/fAF0WcPYMQ

[Peter O'Connor @sunnyflunk1]

A bit late to the party, but this will be a pretty significant improvement for system updates when it gets integrated into moss

[Serpent OS @Serpent_OS]

Another great post from @sunnyflunk1 detailing the research going into our future delta packages in the Serpent OS moss package manager.

Lots of low level juicy metrics =)

We're still making considerable improvements before we start asking people to test the packages.

@sunnyflunk1 back again to document our latest format improvements: Faster installs + smaller packages!

What this doesn't show is, despite adding binary dependency tracking, the Analyse step now runs more than twice as fast on a large package. On my local slow machine, it was 5x faster on a small package (which had only one ELF file).

[Serpent OS @Serpent_OS]

OK a whole bunch of work later, we've now got boulder automatically detecting shared library and interpreter dependencies. We'll refine this to more types as we go along, but now we can add a repository with real working dependencies and quickly exit bootstrap.

Winning.

[Peter O'Connor @sunnyflunk1]

Pushing the boundaries and testing weird cases is vital in getting the best results. A quick 1 liner has led to a reduction in Serpent OS package size, in one extreme case by 10%! Plus we can now extend this idea to push for further reductions in size.

Another blog post here from @sunnyflunk1 in the "Unpacking the Build Process" series. Interesting insights into how we build packages, and next steps for improvement! (boulder, our #dlang based package build tool)

@darkdragon001 @Serpent_OS Because of how moss works, we can actually avoid the overhead of overlayfs entirely while still enjoying RAM builds. It may get some discussion in part 4 or 5.

[Peter O'Connor @sunnyflunk1]

@Kyriusen @Serpent_OS @ikey_doherty The raw numbers are also in the table if you wish to calculate it from a different point of view (say relative to the host).

[Peter O'Connor @sunnyflunk1]

@Kyriusen @Serpent_OS @ikey_doherty How much slower is the host than Serpent OS. Or (host-serpent)/serpent : - means that the host was faster. 70% difference means the host took 1.7x as long as Serpent OS to complete the task.

[Peter O'Connor @sunnyflunk1]

Just writing up another quick piece...

[Peter O'Connor @sunnyflunk1]

@VitaliiAbetkin Gaming support, steam/wine etc

[Peter O'Connor @sunnyflunk1]

Wrapping up the toolchain for Serpent OS, so now's the time to speak up if you want some input...oh and what's that 32bit thing all about?

[Peter O'Connor @sunnyflunk1]

Testing out the performance of the current Serpent OS root (all built with boulder). Much to learn with #clang, many knobs to tune and tweaks to the build system.

Things are about to get interesting!

[Peter O'Connor @sunnyflunk1]

TL:DR Fast dev iteration + a massive reduction in delta size

[Serpent OS @Serpent_OS]

Insights from our own @sunnyflunk1 on how to approach the update delta issue with moss/moss-format. Much #zstd excitement awaits!

Time has come if you want input on the build system from the ground up. Prepare to have your ideas challenged though https://t.co/vMjfa7xttP

[Peter O'Connor @sunnyflunk1]

First stone created from the Serpent OS bootstrap!

[Peter O'Connor @sunnyflunk1]

So not an entirely smooth process. There's a bug with some hardware combinations where the session crashes if the screen blanks or is turned off... So for now I've turned it off as the experience is significantly better (the odd menu oddity and flickering, but nothing breaking)

[Peter O'Connor @sunnyflunk1]

Giving wayland another go, feels like it might be for good. So much smoother than X11!

[Peter O'Connor @sunnyflunk1]

@imdebdut The outcome? yes, that I'm doing this? Unlikely unless it takes some time. Though the initial testing will only be preliminary.

[Peter O'Connor @sunnyflunk1]

Currently putting together a glibc based bootstrap in order to have an actual comparison to musl and whether it's worth using or not.
