I saw this post and it motivated me to do a quick test:
https://phanpy.social/#/hachyderm.io/s/115891592999188880

Stop opening huge files in screen editors.

Screen editors (nvi, vim, etc.) assume you want to scroll,
see context, and move a cursor interactively.
Huge files break those assumptions.

For large files (1GB+):

Inspect: head, tail, grep
Understand structure: awk, sed -n (stream, don’t load)
Surgical changes: ed or sed

Open a screen editor only when you need to rewrite text.

Benchmark (1GB text file):

nvi -> 20.1s (eager line indexing ~25M lines)
vim -> 7.7s (lazy loading, deferred UI cost)
ed -> 4.0s (I/O-bound buffering, no TUI overhead)

Large files don’t need better editors.
They need better workflows.

For huge files, the right solution is not tuning screen editors,
but using the right tools:

shell tools for inspection
ed for known, surgical changes
screen editors when interactive rewriting is actually needed

PS:
nvi chooses predictability over perceived speed.
The slowdown is not a flaw — it’s the cost of preserving
classic vi semantics within a screen-editor model.

Interessante o Anubis mas acho que implementar ele na Bolhinha, numa análise superficial e preliminar, traria mais problemas do que soluções.

Por exemplo, ele não se dá muito bem com WebSockets e o Mastodon usa isso o tempo todo.

What command do you prefer for switching to root?

Edit: I realize now that I forgot a looot of options. So many ways to switch to a root shell. If only I could add more options to a mastodon poll in an edit...

They say AI isn’t profitable. That’s not true.
Twice just this past week, I’ve been contacted and paid to fix problems caused by developers who relied on AI to configure servers.

New blog post!
This is the longest one in quite a while.

Last year, I held a presentation about the basics of Active Directory pentesting, focusing on "quick wins", easy to exploit vulnerabilities with huge impact.
I turned that presentation into a blog post.

The result is a surface-level overview of some of the most severe Active Directory vulnerabilities.

I hope it can be useful for aspiring pentesters and Active Directory admins alike.

#sysadmin

It's probably a good idea to do another #introduction since people change over time, ideally.

I'm haui. I help people & build things that help people. Big #foss enthusiast, #sysadmin by day and #hacktivist at night.

I think all people (and animals) are born equal and should stay that way.

I oppose #capitalism and embrace alternative systems. I dont care about #corporatedemocracy and manipulated "free speech".

I want thirst, hunger and homelessness gone, for everyone, by any means necessary.

Hey #sysadmin folks! Is "short stroking" a hard drive still a thing?

For the youngsters: this was when you used only the fastest part of a hard drive, leaving the slow parts of the disk empty. Short stroking improved spinning rust performance.

I haven't heard of this in years, and it seems that with LBA abstracting the drive innards would eliminate the benefits. (You'd still get extra spare blocks for when the drive starts failing, sure.)

A #SysAdmin / #MastoAdmin Question for folks

Has anyone used mikrotik hardware in anger / in production?

I've had enough now of my Unifi gear causing problems, this is the second gateway I've purchased which exhibits these random lock-ups / crashes and I'm very much over it so am looking at alternatives and mikrotik continues to be one that looks sensible.

Just curious if anyone has much experience using it hands on?

Heyho, I'm seeking an #Internship as #Sysadmin from Sep 2025 to March 2026, ideally in or around #Düsseldorf, but I'm open to remote. I'm passionate about Linux and I'd like to explore the #DevOps route too. See my website https://larmart.de for contact infos and a first impression. - The costs of the Internship are covered completely, it’s a free opportunity to work in a passionate and young Linux fellow. Thank you guys, boost is appreciated 🙏🏻❤️🐧
