pwru VS mdp

if you have a recent enough kernel, this change https://github.com/cilium/pwru/pull/148 means that it will print the reason the packet was dropped in the output - see https://lwn.net/Articles/885729/

There's a whole heap of reasons a packet can be dropped:

[pwru](https://github.com/cilium/pwru) is a fun new tool from the Cilium folks for tracing network packets in the kernel. Like tcpdump but it shows you the full path including kernel syscalls. Lets you debug much deeper than "when the packet gets to this port it gets dropped".

I recently came across another useful utility for debugging unexpected packet drops - PWRU[0] (Packet, Where Are You) by Cilium.

It uses eBPF to try to trace the path of the packet through the kernel. Haven't needed to use it yet, but it could have saved me a lot of trouble in the past.

It depends on what you are presenting. I found [mdp](https://github.com/visit1985/mdp) to be very useful when presenting a tech talk. It is easy to copy and paste from the source material, it can be done all via the terminal, and it views well as a README on github.

Here is an example of a presentation I gave:

It is absolutely possible. Use Lynx for web browsing, use TMUX for split screen, use BC for calculator, use KHAL for calendar and of course use RTV for Reddit. :-) Here is a great list of CLI apps: https://github.com/agarrharr/awesome-cli-apps Here are some of my favorites though: - https://github.com/GothenburgBitFactory/timewarrior - https://github.com/IonicaBizau/idea - https://github.com/jeffkowalski/geeknote - https://github.com/insanum/sncli - https://github.com/visit1985/mdp - https://github.com/astefanutti/decktape - https://github.com/insanum/gcalcli - https://github.com/pimutils/khal - https://dianne.skoll.ca/projects/remind/ - https://github.com/zquestz/s - https://github.com/yudai/gotty - https://github.com/axiros/terminal_markdown_viewer - https://github.com/chubin/wttr.in - https://github.com/schachmat/wego - https://github.com/tldr-pages/tldr

I use pandoc to convert markdown to powerpoint decks, it's a great workflow as you can preview and tweak the content and then apply the firm theme before the presentation.

If all you need is text on your slides, then mdp could be fun! I used it during an interview a while back.

Hmmm.. interesting. I used mdp a few times - perhaps I should give this one a whirl.

Have you ever heard of terminal based presentations with mdp?
