Welcome to the dark side of Rust :)

A bunch of funny Rust trivias! (by @Jonhoo)

A nicely looking and informative rust cheat sheet. Not sure when it's helpful, but it looked like good place for learn for certain unfamiliar practices.

DALLE-2 has a secret language. "Apoploe vesrreaitais" means birds. "Contarra ccetnxniams luryca tanniounons" means bugs or pests.

The poster asked DALLE-2 to produce seemingly nonsense words, and then prompt DALL-E with these words and find that these nonsense words contain meanings coherent to the initial prompt.

It's no longer seem like a mystery to me after I read explanations. But it's undoubtfully a super interesting phenomenom.

See more discussion in https://news.ycombinator.com/item?id=31573282.

Ask questions while you read mathematics grants deeper understanding. There is no point in aiming for speed. You must learn to read to learn how to write articles about mathematics. The article also includes a detailed example on writing about birthday paradox.

A post by Julia Evan on ftrace - a feature in kernel to trace any kernel functions! trace-cmd is a command line tool that makes it easy to do so.

A searchable list of Linux x64 and x86 syscall numbers. Also shows the kernel source code where the syscall is defined, as well as the registers for each of the arguments.

Interesting summary of the evolution of Unix command line argument conventions.

An educational article into how mechanical clock works with a LOT of interactive demo to play with!

"Shibboleths" are phrases you use to tell if a person is of a geniune member of a society or a pretender. The article discuss some of the positive and negative Shibboleths a vendor may use for distributed systems:

Positive:

• We made the operation idempotent
• The system makes incremental progress
• Every component is crash-only
• We shard it on <some reasonably high cardinality value>

Negative:

• Our system is Consistent and Available.
• at-least-once and at-most-once are nice, but our system implements exactly-once
• I just need Transactions to solve my distributed systems problems
• I will take a distributed lock

("Shibboleths" may be best translated into "暗號" I suppose?)

A hilarious and potentially useful site. It's an epitome for modern double speak in professional occasions.

A comment (https://news.ycombinator.com/item?id=31226899) demonstrated how to use GPT-3 to generate such language.

I also learned about the concept of PDI: https://en.wikipedia.org/wiki/Power_distance

A fasterthanlime video on injecting code to a foreign Windows processes.

A really informative article that explained a lot of mysteries I previously had.

For example, given that a black hole can be described from just three numbers and thus "highly ordered", how is it that a black hole is said to have a very high entropy?

The biggest takeaway from the article (to me) is that: entropy is not about disorderness, but rather about the amount of information (microstat) packed in an apparent phenomenon (macrostat).

Not only the answer help solved a mystery I had for weeks, it also demonstrated how to solve the same kind of problem using auditd. Great to learn about it!

Interactive explanation on X Window systems, including the interesting history limitation and workarounds, and the mess brought up by the need of direct gpu-access.

Interesting article comparing x86 with other IA by Raymond C.

An interesting article on why there is half megabytes of empty bytes in every music file.

Alongside the desire to brainwash people, the regime also wants to remind people of their power. When citizens are bombarded with propaganda everywhere they look, they are reminded of the strength of the regime. The vast amount of resources authoritarian regimes spend to display their message in every corner of the public square is a costly demonstration of their power.

Propaganda is intended to instill fear in people, not brainwash them. The message is: You might not hold pro-regime values or attitudes. But we will make sure you are too frightened to do anything about it.

Insightful! Considering China on these days, if the torrent of stupid propaganda abated, it would be resonable to suspect that Xi's power has been suppressed probably by his political enemies.

I find this documentation as interesting as DALL-E 2 itself. It underlines a number of potential "misuses" and mitigation.
