#3dprinting supports question:
Any tips/tricks on setting up supports in a slicer such that:
a) they actually support the print
b) are not a major PITA to remove
I had to spend an hour with the cutters just to get the supports out. Often I had to tear them from the print, fearing I'd damage the 10h print.

It's amazing how the dried worms we bought for our chickens smell exactly like prawn crisps.
Not going to explore this thought further...

I want to #translate some educational videos for my kids to understand.
Given the immense amount of #AI sites that claim to do perfect dubbing with lip syncing etc, it must be something that's "easy" to do (otherwise there wouldn't be so many sites claiming to do it, my logic goes)
Is there a self-hosted solution (voice/audio translate is enough) that I could try running locally, with models available for "smaller" European languages (not just German/French/Spanish/Italian)?

Yesterday's #comet #astrophotography #timelapse - the weather could not have been better.
Unfortunately the light leakage from inside the house is visible on the window pane reflection despite my best efforts.
Source data: ~3h of RAW 15s exposures using #gphoto2 + #raspberrypi (20GB total). Processed using #darktable #cli (amazing!) into #jpegxl 16bit intermediary near-lossless frames (300MB total) into final 10bit #av1 social-media optimized video you see here, (~750KB). That's over 25000:1!

@npub19lt…qfjk Oh wow, even `view-source:...` loads one character at a time! Nice!

I had to use a GUI instead of CLI remotely (I find it hard to adjust images without seeing the preview) so I fired up this:
$ export DISPLAY=:11
$ Xvnc $DISPLAY &
$ awesome &
$ app &
Then I connected from my phone with a regular VNC viewer (all over Wireguard).
What are my options with Wayland for this kind of "ad-hoc start an app and VNC to it"?

I have a million MicroSD -> SD card adapters lying around, but suddenly when I need one of them, they all start playing hide&seek.

I haven't stayed up late for a very long time, but yesterday (today?) I had to set up this medieval Factorio spaghetti to get research going for a monument...

My 4yo #Android phone warms up during regular use, to the point I can't hold it in my hand, and it's very slow, most likely due to throttling. The battery needs to be recharged twice a day, a replacement is already ordered and on its way.
I'm wondering if a new battery would fix the overheating, or I should be worried about something more serious (Nexus 5X?).
Newer Android versions seriously neutered CPU meters (for "security") so I can't say if something is hogging resources in the background

I'm sorry Reddit, but what? What is "the app" going to change anything about "unreviewed communities"?

I've captured a series of star photos overnight during a rare clear sky with my #DSLR, and now I want create a #timelapse.
Is there any #FOSS that specializes in this? The issues that I need to figure out:
a) I have quite a few hot pixels, but they are consistent, so should be easily masked
b) I want to downscale to full HD
Especially the second one is a problem, as "usual" photo scaling tends to average, which would dim single-pixel stars in my case...

Any recommendations for #Prometheus long term metric storage?
I tweaked Prometheus to store a year's worth of data, but one unclean shutdown and I've got a corrupt WAL block, which it doesn't handle well (needs 20GiB RAM at startup).
There are many options (#OpenTSDB, #Graphite, #InfluxDB, ...), any reasonable low-maintenance / low-resource storage which I could write from Prometheus and show in #Grafana dashboards?

@npub1gfd…7gg6 "Market cap" is simply "share price currently selling at" * "number of all publicly traded shares" (oversimplified).
It's not "how much they have in the bank", it's not money they can use to buy anything, it's not something to be taxed on since it's not income (until they sell their shares), it's not even "their" money. It's just that investors are OK trading the Apple shares at whatever value it's currently trading at.
I'm not defending them, just trying to explain the terms used.

@npub18nd…ax9z my computer has become unusable because of (suspected) nvidia drivers >525.xx.yy - if the display comes up (no "Idling display engine timed out"), it only updates if I move the mouse.
Rolling back to 520 was not possible due to some kernel API changes that I didn't have time to resolve.

Time to scrub my 4-drive #btrfs array: 54 hours
And it will only grow...
I made a mistake replacing the aging 7200rpm drives with more affordable 5400rpm ones, even though on paper they have roughly the same max read speed, but it's the random read performance that matters...
