My setup is a distraction — netbook case

Posted on By Shrimple No Comments on My setup is a distraction — netbook case

My lately blog posts have been written in the built-in editor of WordPress (earlier, it was WordGrinder). More than I should, I care about autosave being reliable, and that of WordPress has a somehow bad reputation (no idea why so far), although what I know is it autosaves only every minute. I like to write…

Getting TLS1.3 Key Log from Go application with requests by a library, and using it in Wireshark

Posted on By Shrimple No Comments on Getting TLS1.3 Key Log from Go application with requests by a library, and using it in Wireshark

Today I wanted to sniff on TLS traffic of hell, a “mastodon client” that seemed to not want to work with things that aren’t Mastodon. The network calls are mostly made from within a library, hellclient-go-mastodon fork of go-mastodon.

SSLKEYLOGFILE turned out to be a standard, now even RFC 9850, for TLS client instrumentation. But Go standard library doesn’t simply write the secrets to a log file in coupling with the obscure environment variable. Not much libraries seem to do it — just programs like major web browsers and curl. (Perhaps bizarrely, this Haskell package adds it coupled with an environment variable — introduced to one’s Haskell code by means of adding nothing more than an import statement.)

Distributed file version management in 15 minutes of Bash

Posted on By Shrimple No Comments on Distributed file version management in 15 minutes of Bash

You don’t always need to have all the tools at your disposal, but you may want to have some way of checking in your file edits. CVS is too powerful and has a lot of unnecessary parts, while not being distributed. You may not need to keep everything in deltas. So why not just write…

Forcing KWin decorations and MS Edge’s 1cm shadow gradient

Posted on By Shrimple No Comments on Forcing KWin decorations and MS Edge’s 1cm shadow gradient

In Plasma (or just KWin), if you want to have window decorations, of an application that doesn’t like having anything outside its own, behave in a uniform way that you configured in your setup, you launch yourself the “Window Rules” by either

  1. Clicking on the titlebar of some normal window and picking “More Actions” and “Configure Special Window Settings” or “Configure Special Application Settings”, then going the arrow back to get out of creating a new rule or customizing an existing one (the window name, however, will remain referring to which fo the two options did you pick), or, more reasonably,
  2. Going to Plasma System Settings, from there under Workspace to Window Management, and picking Window Rules.

There, you use “Add new…” to create a new rule, use the Detect Window Properties tool to pick a window and select what scope do you want, consider the “matching whole window class” selector at random (occasionally giving it more thought), and then picking “No titlebar and frame” and setting it to “Force” with “No”, then picking “Instantly” above the Apply button and clicking Apply.

This lets you comfortably shade/unshade (feature only active in X11… https://bugs.kde.org/show_bug.cgi?id=377162) a maximized jetbrains-idea or code code with your mouse scroll wheel if you configured your KWin so; you may also want to do the same for “Ignore global shortcuts” so that your Alt-drag works for moving and resizing these even if they like having Alt for themselves.

Descent into the Microsoft Edge madness

But then if you do the same for Microsoft Edge…

when DMI info like Serial not in hostnamectl output

Posted on By Shrimple No Comments on when DMI info like Serial not in hostnamectl output

At a workplace, someone may expect that your Linux distribution, presumed to be some outdated Fedora, will have hostnamectl print out the Serial Number and SKU from Desktop Management Interface (DMI). But they might not expect that your version, an old Ubuntu LTS to Microsoft Intune requirements, doesn’t print these out. Someone may even be…
