Not OP, but any macro lens will do the job. You're not likely to be shooting at a wider aperture than f8 given that you'll need some depth of field to spare. (Even if you use a specialised copy lens with a flat field, the film won't be perfectly flat anyway.) So given that you're shooting an imperfectly flat piece of film at a narrow aperture, differences between lenses will be small. I use an ancient f3.5 Micro-Nikkor. These are cheap and plentiful in the second hand market and can be adapted for most cameras.
As far as the camera is concerned, it's a big advantage to have an electronic shutter. The effects of camera shake are magnified with macro photography, and a mechanical shutter can make the results observably softer. I am cheap, so I use an old DSLR in T mode and use a Raspberry Pi to turn on one of those backlit sketch pads for a fraction of a second to expose the image.
To add onto this - I highly recommend you take advantage of light rooms Flat Filed Correction tool, it will eliminate lens vignetting which can cause issues when inverting. This article elaborates https://www.pixl-latr.com/defeating-the-orange-haze-lightroo...
That looks very useful for use with older lenses. With a modern lens, shouldn't Lightroom be able to apply a precise vignetting correction based on the image metadata and the lens parameters?
To be fair, it was all new back then and people were playing with ideas, so a 3d file browser seemed like a cool idea. A bit like the metal roller on the Paris Metro ticket machines https://www.youtube.com/watch?app=desktop&v=9SjBfRA3YzA
The discoverability on those things is definitely lacking. I think it took us five or so broken touch-screens before my wife noticed that you could use that to select menu options instead! I guess once you know it's fine though? Feels a bit dated compared to the typical touch & go card payments elsewhere in Europe now though.
I couldn't work it out for a good while, because it's the most unintuitive UI I have found on reasonably recent ticket machines. Once you know how to use it, it's ok.
ProTip: if you travel from London on a train, the buffet sells Paris Metro tickets.
Yes, it was a SGI application. Probably used in the movie Hackers.
There was also a Doom file manager where you'd use BFG to nuke a directory. I only found one for Doom 3 but this also existed with original Doom. Nowadays, BFG is only used to nuke git repos.
Doom process managers where a thing for a while too, 20 years ago. Using the BFG on a crowded room of processes usually resulted in a system crash. Hunting down a stuck program and shooting it in E1M1 was pretty neat though. Your comment reminded me of playing with this in MacOS X a long time ago.
There was a bunch of "demo" applications bundled in Irix, some more some less useful, that were used to showcase the capabilities of the systems. File System Navigator was, afaik, one of them (similarly there was bundled "dogfight", a networked flight simulator game).
PP probably refers to those very cheap USB soundcards, usually shaped like a dongle, with two mini jacks, sold pretty much everywhere. I tried a couple in the past (can't confirm if the chipset is the same) and they definitely sound better than expected from a device that cheap, however be aware that manufacturers often save on parts number or quality to reduce costs therefore it can be a hit and miss, with some of them making noises or offering inferior quality.
* USB soundcards used to work on Android but in recent tests they failed again for some reason
* Avoid any dongle that supports "special effects", "gaming", etc. Even if they can be disabled, it's such a pain.
* Dynamically adding/removing soundcards can affect your computer's notion of "default microphone", particularly relevant for video chat. Some apps this takes effect immediately, some after quitting the app.
DRBD was nice to use. Great thing about it is that you can put it below the existing filesystem. I don't remember how it works, maybe it puts metadata at the end of block device so filesystem should be shrinked before
I remember moving a huge NFS partition which was experiencing constant writes to another server with DRBD. With almost zero downtime. So is a nice tool if you want to move a filesystem with such huge amount of files that even iterating over the file tree takes hours
I was eyeing it pretty heavily recently, considering using it in my homelab for distributed ZFS. I wound up using Ceph since Proxmox has native support for it, but I still may try it out.
I’d like to be able to create zpools for DBs to take advantage of snapshotting, but combining ZFS and Ceph on the same underlying disk (even if they are enterprise NVMe drives) is fraught with peril.
