Just a simple script that reminds you to take some rest every n minutes

So I want to integrate a comment system to my blog.There are many many comment service providers like disqus. Even for a static site, you can add comment support simply by inserting a javascript snippet into the page.

But what about … zero JS?

Let’s bring “cursed” programming to a whole new level.

Helpful or not, I’m taking some notes while reading the book “Expert C Programming” by Peter van der Linden.

Quick ssh forwarding setup:

This post resolves the problem “how to pronounce 0x4_2000_0000_0000_0000” once and for all.

I wasn’t me who abandoned the relationship!

This article brings up the topic that the SGX Enclave, especially the DCAP Quoting Enclave¹, can have too many “identities”. This can be more or less an obstacle in the way towards formal verification. This was partly my student research project in the uni.

I prepared a virtual machine image for a course in the uni. The last stage – cleanup, is less trivial than I expected. I’ll take some notes, before I forget. This could serve as a checklist.

This is a Debian 11 guest system

e.g. send to a program’s stdin via its PID.

I use this little script for my stream set up at live.shrik3.com

It does two things:

• print the current song, and the most recent n songs in the terminal
• log all the played songs to a file

Note: needs spotify-cli as dependency

It was a stupid proof-of-concept attempt but it fucking works and I kinda like it.

I have (and will have more) many notes on this blog on Vim, the post serves as all-in-one reference page.

Concepts: Wait-free and Lock-free

An object impl. is wait-free if every thread completes a method in a finite number of steps:

• NO mutual exclusion (thread should not halt in critical section)
• NO while loop (that may keep spining..)

An object impl. if lock-free if in an infinite execution infinitely often some method call finishes(in a finite number of steps)

How is color space defined and what exactly is “color” from a machine’s point of view.

TIFU by letting pacman upgrade the postgresql a major version (13->14). Then the postgresql service failed to start.. Anyways here is the fix.

also a nice thing in the AUR: the postgresql-old-upgrade package. It provides the binary for the older version of psql under/opt/postgresql{VERSION}

Honestly I don’t think over-functional completion and diagnostics give you any productivity. The same is true for highlighting: if you highlight everything, you highlight nothing. It’s a harmful mentality to think “oh I have to have the best tools before I get started.” No, tool is just tool, the purpose is production.

So this is what I want:

• basic syntax highlighting.
• completions based on current project.
• jump to definition.
