lnav is a terminal-based log file viewer (TUI) for #Linux, #FreeBSD, #macOS, and other #Unix like systems. It combines the functionality of tools like tail, grep, awk, sed, and cat into a single interface. It also allows you to run SQL queries against your log files to build reports and offers basic support for Linux containers like Docker. lnav – Awesome terminal log file viewer https://www.cyberciti.biz/open-source/lnav-linux-unix-ncurses-terminal-log-file-viewer/

My question would be this why you want to do anything to address the (context-dependent) conclusion that “Python is slow”? ;-)

How I would address [1] with any Python3 dot release would be:

1. LATENCY: Manual driver/controller in the app for gc.* for the sake of predictability in timing. Run it when your app is idling. Do not run it at the hot spots.
2. BANDWIDTH: Use a freaking C-library for the payload processing. By practical means all of them have Python bindings.

I finally released b4-0.14.0 with some neat features. Read the announcement for details:

Still my #TUI file manager of choice after all these years.

Closed my tpm-rs bug because I do not want to contribute to that project: https://github.com/tpm-rs/tpm-rs/issues/71#issuecomment-2171360982

Why? I think mine is better or will grow so much better than this. It is more idiomatic #Rust, and generally less layered and more lean and mean ;-)

I will review merge requests for mine tho, on the basis of common sense and code quality tho: https://gitlab.com/jarkkojs/tpm2_library/-/issues

TPM2 command encoding with #bincode and #serde:

            let options = DefaultOptions::new()
                .with_fixint_encoding()
                .with_big_endian();
            buf.extend(&options.serialize(&(Tag::NoSessions as u16)).unwrap());
            buf.extend(&options.serialize(&22_u32).unwrap());
            buf.extend(
                &options
                    .serialize(&(CommandCode::GetCapability as u32))
                    .unwrap(),
            );
            buf.extend(&options.serialize(&(Capability::Handles as u32)).unwrap());
            buf.extend(&options.serialize(&HR_PERSISTENT).unwrap());
            buf.extend(&options.serialize(&1_u32).unwrap());

Well, these authors cut right to the chase in this paper!

Just noticed that #aerc has native support for #zoxide: see :z. #email

Would make porting all sorts of old protocol stacks to #Rust so much easier if the enum fields could have aliased names. #rustlang

I'm looking into repealing and replacing the error type with this with the error type from my lab project: https://github.com/tpm-rs/tpm-rs/issues/71

Language Server Protocol really would need a competitor with a #plugin based architecture.

Then editor and analyzer could have:

1. A better memory and caching strategy.
2. Both faster performance and lower operation latency.

#LSP is IMHO is exactly like the worst ideas of lrzsz modified to work as a language analyzer.

#telescope is awesome with the #kernel tree #neovim

The work on #bootc Is coming along very nice! This morning keynote by @cgwalters, Dan Walsh, and Stef Walter was very nice to see the current state of it in #Fedora and CentOS Stream. #devconf_cz

#neovim in #fedora 40 does this when opening a #lua file:

When cargo publish -p tpm2_cli , I need to

tpm2_call = "0.1.1"

… while building locally:

tpm2_call = { path = "../tpm2_call" }

How to sort this out in “idiomatic manner”?

#rust #rustlang

A crate for #TPM 2.0 library protocol, or beginnings of it: https://gitlab.com/jarkkojs/tpm2_library/

Sub-crates:

1. tpm2_call for TPM 2.0 library protocol shenanigans.
2. tpm2_cli for a command-line interfaces.

Development process:

• https://www.conventionalcommits.org/en/v1.0.0/
• https://semver.org/
• Signed-off-by’s.

I aim to do cli first as Linux tied but it could also have e.g. Windows backend. tpm2_call will be portable between operating systems.

#TPM2 #Rust #rustlang

Not really a real project. I've been ad-hoc scripting with #python since 2005, and wanted to learn how to "devops" a properly pipeline at #gitlab, with a release ending to the #pypi: https://pypi.org/project/eth0/

PS. I deleted 0.1.0 tag and release from pypi, because the tag was not signed ;-) you could never trust it...
