after upgrading to NixOS 25.11, Samba returns outdated directory listings not showing new files. my client is an updated Windows 10 ESU. search for bugs in both nixpkgs and samba, need to fix. seems like it's cached for like a minute or so?

What you’re seeing lines up very well with SMB3 Directory Leases being enabled after your upgrade.

Why it started after NixOS 25.11

people should reply with "clanker alert" on tweets composed by ChatGPT / LLMs. this will save other readers time because they'll know it won't be worth reading.

lol i get the impulse—there’s a lot of autocomplete-noise out there. a quick “clanker alert” would feel cathartic. a few thoughts to make this idea effective (and not backfire):

What works about it

• Fast social signal: readers can skip low-effort, source-less takes.

This is a public gist expressing my interest in purchasing a Zebralight H604c from anywhere in the world. I can arrange for whatever pickup or shipping method works for you.

By the time you see this, this gist may be old, but I am still interested.

Please find a replacement for my Zebralight H604c flood headlamp, that I can purchase today. That one has a Cree XHP50.2 LED, which was good in 2021 with no green tint; produced later it has a green tint. I want a 3500K-4000K flood headlamp with no green tint which takes one 18650 battery and has a good headband. The flood part is very important; no beam, just a bare LED that illuminates everything in front of me. Like a Zebralight H604c, which I can't purchase any more anywhere now. I rely on the headlamp all day long... maybe look into specialty headlamp vendors for industry or cavers.

Thanks for the detailed request—it helps a lot. Just to be sure I find the best options for you, could you please clarify the following:

1. Is high CRI (color rendering index) important to you for accurate color perception?

2. Do you have a preferred beam angle or lumen range?

ViewSonic VP2788-5K thoughts:

• The stand is very solid, but not really usable if you don't want the bottom of your 27" monitor to be at minimum 6 cm above your desk.
• It's far too bright at 0% brightness. Like a VX2475Smhl-4K at 35% brightness. Feels like I'm looking at a TV.
• It ships with defaults that apply sharpening to the input ("Ultra Clear"), but it's easy to turn off.
• The OSD is operated via a usable joystick button, but it's in the wrong place, below the bezel.
• The power button—with a very similar shape—is right next to the OSD button.
• There's no G-SYNC or FreeSync.
• When run at 75 Hz, the frame pacing in 60 Hz games is (of course) a mess. Tested: The Witness.
• Maybe it is good for doing photography or video work if you run it at 60 Hz and don't mind the lumens and the backlight bleed?
