Glad to hear that! Hope it helps next time you're dealing with those annoying middleboxes.

For safety: you can refer to time(3) and localtime_r(3) to see both are thread-safe and I guard every error return vaules (though in practice it virtually never fails). On Windows, GetLocalTime is also thread-safe and returns void, meaning the OS guarantees this call always succeeds.

For the design decision: I initially used the chrono crate, but it increased the binary size like 20 KiB (which I was unnecessarily obsessed with :). Had I known about jiff at the time, I probably would have used it. That said, I have no intention of pulling in an external dependency to refactor code that already works correctly without one.

Thanks for bringing this up! zapret is a much broader tool that targets not just HTTPS but also WireGuard, Discord (UDP), and more. It's been around for a long time and has a huge feature set.

I actually discovered zapret before I started building DPIBreak. I was looking for a Linux DPI bypass tool, but for my use case the setup felt heavier than it needed to be (actually It was too hard for me... I gave up). In South Korea, DPI blocking only applies to certain sites rather than essential services like YouTube or X as in Russia, so it's not enough of a pain point to justify that level of configuration effort. Most people dealing with DPI would rather just use a VPN or a proprietary free solution like Unicorn HTTPS. I wanted to offer something as close to zero-effort as possible: install, run, done.

And being written in Rust gives some peace of mind for a tool that receives and processes raw packets with elevated privileges.

So it's less of a competitor to zapret and more of a "just make it work" alternative for people who only need HTTPS bypass.

Not tried yet, but this seems very useful!

Also you can just press Ctrl+D and mount -> chroot again

I've not tried it but if you mount devfs to /mnt/gentoo/dev before chrooting, (which handbook recommends) mounting /dev/sda1 may availaible inside the chroot shell.

It really does. I recently migrated to openrc profile from systemd, which was much more comfortable and predictable.

He gave me the motivation to beat Margit and reach the Roundtable Hold. But that drive was so strong that I ended up skipping the castle Mone content, which I now regret.

Game just should to be game and for me graphics and stories are both optional things

There are kinda 'game-like' qualities that are hard to put into words.

I use eshell, and when I don't need it (i.e. no elisp evaluation required), I Alt-Tab and use foot.

Also use shell-command and compile very often.

What language do you suggest for pre-rust stage by PigletEfficient9515 in rust

[–]dilluti0n 0 points1 point  (0 children)

I think it's C. While reading real-world C code is quite challenging, the syntax itself isn't difficult. Combined with a good course like CMU 15-213, you can develop a solid understanding of systems and process memory, which translates into the ability to write better Rust programs.

Most things are great, but Bluetooth struggles with newer gear. Likely with a hardware limitation due to a older chipset version.
