A great post on an interesting nteworking problem: how does distributed servers send packets to the internet while sharing a common set of IP addresses?

For ingress there is the technique of anycast which allows the client to connect to any one of the servers, but for egress it's a lot more trickier because the client needs to know about where the traffic comes from.

Turing famously showed that computers can’t decide whether your code halts. But in 1951, Henry Rice proved a much more devastating result: “computers can’t decide anything interesting about your code’s input-output!”

A lot of Linux command line tips and tricks.

After installing on a usb stick, it can boot any iso files from the usb file system, without the need for dd or additional usb-boot maker tools. Looks quite interesting.

I feel awestruck when looking this website. I also learned how we do not see through the same types of astrobodies through the time and space, which is contrary to my former misconception.

Anna’s Archive is a project that aims to catalog all the books in existence, by aggregating data from various sources. We also track humanity’s progress toward making all these books easily available in digital form, through “shadow libraries”.

An alternative to z-library. RIP.

I learned some USB HID debugging utilities from this article. Saving it for later reference.

Interesting though useless knowledge on the evolution of the term "boilerplate" in programming context.

TL;DR: first it refers to the plate used to roll into water boiler cylinder in the steam age. Then in linotype age there is a technique to make mold lead into the lines of text for printing. These plates of lines of texts looks similar to boilerplates. And the connotation of "copy-pasted" text comes from the usage of these plates been casted several times and sent to various new publishers for printing.

An UX idea on rich text editing. My favorite part is the clever way to distinguish inside and outside a formatted block.

How does Photoshop's layer blending mode (or CSS mix-blend-mode) work? This article greatly illustrated with examples and the exact formulas.

A tool that helps you pore through papers. It is capable of explaining selected sentences and interactively answer questions about the paper. From my usage experience it's already quite helpful.

Linux server issues troubleshooting scenario game on a VM with root access. Looks fun to play. My server never finishes being created though, I guess it may have suffered from HN hug of death.

“Our theory is that consciousness developed as a memory system that is used by our unconscious brain to help us flexibly and creatively imagine the future and plan accordingly,” said author Dr. Andrew Budson. “We don’t perceive the world, make decisions, or perform actions directly. Instead, we do all these things unconsciously and then—about half a second later—consciously remember doing them.”

That is mind blowing. "You" may be not the one who's in charge. The unconscious "you" does everything automatically and "you" takes the credit as the agent.

I first heard about this theory from Blindsight by Peter Watts. It was a really interesting idea.

TL;DR:

1. The application creates a wl_data_source object, indicating that it’s going to offer data to other applications.
2. The application adds the mime types that it can handle to the data source (with wl_data_source::offer)
3. The application finally calls wl_data_device::set_selection, to indicate “I’m taking ownership of the clipboard, and the above created wl_data_source is what I’m offering”.

A rather interesting thought and it looks quite likely. Albeit for the current stage I'd argue AI would be most useful in replacing the management roles on organization, like in a warehouse.

This reminds me of the colluding ship Theseus with its vampire captain Jukka Sarasti.
