@snonux > Most of my work is done in the terminal anyway.

Haha, yes! That's why over the years I was gradually moving towards the least amount of overhead on top of what I actually need and use.

From GNOME, I switched to XFCE, then to i3, then to xmonad. Curious what will be my next local optimum when the time comes 😅

ferki, 6 days ago

@snonux Yeah, that rabbit hole is real, though with both i3 and xmonad I only had to invest in the initial setup, then I could afford not to think about it for years.

I guess that's because I want a minimal approach with least amount of distractions and most amount of screen pixels for whatever I'm focusing on at the moment ^^

Since I spend 90+% of my attention in terminals, that's where I spend most of my optimization effort, and the DE/WM itself is just an incidental accessory for me too.

@snonux I mostly used only the builtin display of my laptops, and I now have a 24″ external one for my business. It's important for me to have the same (FHD) resolution, so my mental workflow is independent of which screens I'm using.

My window tiling approach is either the window gets full screen, or the WM distributes windows in an even grid keeping window sizes close to the aspect ratio of my screen (with a rarely used toggle to prefer horizontal or vertical split for the first split).

@foone That's why I prefer empty queues.

@kta I've found the following an interesting read a while back on the performance and robustness considerations of running #PostgreSQL on #ZFS:

@jan Sounds interesting!

Adding -i or --itemize-changes to the rsync options should make it "output a change-summary for all updates", like this:

>f..T...... filename

If you add it twice, it should output it even for unchanged files on recent enough rsync versions.

The manpage of rsync explains the meaning of those flags. For example the above is:

> means the item is being received
f means it's a file
. means unchanged attribute
T means the modification time will be set

Hope this helps!

@jan Sooo...did --itemize-changes help explain why rsync thinks it should sync specific items again?

I'm curious what's causing the behavior you described 🤔

@mid_kid @oddly Yep, GitHub pull requests may work, and the official bugzilla has a dedicated GURU product to collect issues:

https://bugs.gentoo.org/enter_bug.cgi?product=GURU&format=guided

In other words, it's possible to open tickets as usual, including ones with proposed patches.

Happy hacking!

@oddly Sounds great!

Thinking more about it, bugzilla may work a lot better for sending patches because:

• the gentoo/guru repo on GitHub is only a mirror of the real repo, so merging pull requests there won't work directly
• even if that would work, GURU maintainers in general don't have permissions to merge stuff inside the gentoo organization on GitHub

At the same time, bugzilla tickets are assigned directly to the maintainer of the ebuild in question.

If you are impatient to learn about the approach, I blogged about it earlier at https://blog.ferki.it/2023/04/24/host-gentoo-dependency-tarballs-as-github-releases/

@ovid Hmm, let's see:

Larger uses: BASIC, Turbo Pascal, C, Bash, PHP, Perl

Smaller extent: Haskell, Python, Go, AWK, JavaScript, Ruby, C++, Lua, Vimscript

People keep telling me I would enjoy (Common) Lisp, but the proper project I could use as an excuse haven't found me yet 😅

@musicman How about discovering the job market around PostgreSQL, interviewing various companies about their work culture and hiring approach, then post an update each month?

ps.: seeing the weird circumstances around the assignment, I originally wanted to mark the above as joke/sarcasm, but the more I think about it, the more I'm convinced it would work as a serious topic to cover.

@peateasea Thanks for publishing and sharing!

If one would like to use a core module instead of try_load_class() from Class::Load, they might be interested in can_load() from Module::Load::Conditional:

https://metacpan.org/pod/Module::Load::Conditional

Particulary in tests, one may also be interested in either of:

• Test::Requires: https://metacpan.org/pod/Test::Requires
• Test2::Require::Module: https://metacpan.org/pod/Test2::Require::Module

Hope these are useful additions for readers wishing to avoid stringy evals! Happy hacking :)

@peateasea oh, thank you for including it in your post! :blobcataww:

I'm glad you found it so useful!

@peateasea To make vim show non-breaking spaces as something else, configure it with something like:

set listchars=nbsp:‗

Then the :set list command shows the ‗ (double low line) character in place of each non-breaking space without actually replacing it in the file, making it easier to spot for humans.

Use the same to also reveal other normally invisible or hard to spot characters and situations (tabs, trailing/leading spaces, long lines continuing off-screen, etc.)

Happy hacking! :)

@rrwo Check the debug output with rex -d to see which SSH implementation Rex picks up under the hood.

Key auth works and configured differently between Net::SSH (based on libssh2) and Net::OpenSSH (based on openssh binary).

If it works with the ssh binary manually, I guess Rex picks up Net::SSH under the hood either explicitly, or due to missing Net::OpenSSH. Then either libssh2 needs a hint which key to use, or Rex needs a hint to use Net::OpenSSH instead (which is the default, if present).

@rrwo Let me know if that's already useful enough to debug and solve it for you.

If it needs a bit more work, it might be best to discuss on our support channels: https://www.rexify.org/support/index.html

I suggest a chat on IRC/Matrix, or perhaps via my Open Source Office Hours would be ideal for a more interactive session.

@rrwo On second read, I see that agent forwarding and pty allocation are also part of the CLI options we might need to tell Rex about.

Let's debug your use case together on a better medium. I have to rush away from the keyboard now, but expect to be online around CEST 15:00-ish again, please ping me or others on IRC/Matrix (it's the same room).
