What they believe
-
When a system's performance problem seems mysterious, you eventually have to stop testing the suspected component and isolate other layers instead.
The useful lesson isn't "disable LSO." It was that when storage is mysteriously slow, eventually you have to stop testing storage.

Performance-related command-line flags represent qualitative changes to restartability, buffering, or concurrency, not levels on a continuous performance dial.
/Z, /J, and /MT are not levels on a performance slider. They change restartability, buffering, and concurrency.

Migrating a Synology NAS to a UniFi UNAS Pro 8 with Robocopy, SMB Multichannel, and Surprising Performance Traps Said 23 Aug 2026
A server's real network throughput can exceed what its single fastest port suggests when a protocol supports channel bonding across multiple links.
SMB Multichannel can make an old NAS with several gigabit interfaces much more capable than one might assume from looking at any single Ethernet port.

Craftsmanship, taste, and human judgment remain valuable in software development despite AI-assisted coding tools.
There is value in good taste, there is value in craftsmanship, and there is value in human judgment.
Is the craft dead? Said 9 Feb 2026
AI-assisted coding will generate a lot of low-quality output that developers will need to clean up, even as it also produces good results.
I think that there will be lots of work for us cleaning up after the slop, but if you know what you're doing AI augmented development is going to get you some amazing results
Is the craft dead? Said 9 Feb 2026
Impressive one-shot AI coding demos are not a good way to judge AI coding ability.
People should not be judging AI-augmented coding by "1 shots."
The danger of glamourizing one shots Said 4 Feb 2026
Programming is essentially the craft of turning ambiguous ideas into precise, specific instructions.
It's not trivial to one shot something unique, because programming is the art of making the ambiguous incredibly specific through sculpting.
The danger of glamourizing one shots Said 4 Feb 2026
As AI takes over more of the coding process, clearly specifying goals and exercising good judgment will matter more than ever.
As high-level programming cedes way to the prose compiler, making your goals and specs well understood to the ambiguity loop and showing good judgment is going to matter more than ever.
The danger of glamourizing one shots Said 4 Feb 2026
What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
