This is a composite of one meteor LRPT pass and 4 NOAA APT passes (with false colour) from 2023-07-28, the first day of meteor-m2 3 LRPT.
I resized and JPEG compressed this image to not kill your internet connection but the original 109MB image is here.

All composites here are produced with SatDump.

Some more composites of this day are below (lower resolution). All of the titles go the the original PNGs.

only NOAA APT:

and with NOAA HIRS from DSB because why not:

longer HIRS

Hello there. I used to run a small instance for a few of my hobbies but I ended up shutting it down before anyone actually used it. Most of the other topic on there have already moved to custom instances or communities on big instances but this one hasn't yet. I dislike opening yet another community on lemmy.world but I don't think it's suitable to use a personal instance for a community so I ended up making it on lemmy.world anyway.
It's probably for the best because my server is already overloaded, but what do you think? should I host it or just leave it here?

Can someone help me with how peertube P2P works? I can understand how ActivityPub is used for all the "social" parts but I'm a bit confused about the actual video player.

Redundancy:
I have my own instance and I made a redundancy of a video from the blender instance. if I watch the video on my instance I see 2 peers, my instance and the blender one. I can seen both in Firefox dev tools.
If I watch the same video on the blender instance I see 7 peers, the blender instance, mine, and others. why are these extra peers not showing on my instance? do I need to do something? If I watch the video on one of these other instances mine does show up in the their peers list.

I also made a video from framatube redundant but my instance doesn't appear as a peer on framatube.

Client P2P:
If I watch a video does my browser share It over P2P? if so what is the point of this? it seems to lose the video as soon as I leave the page so this functionality seems a bit useless to me.

EDIT: Answered in comments.

BitTorrent:
If I download a video I get the option of a BitTorrent torrent. If I seed this torrent can it be leeched by web clients? I tried and It doesn't show up in the peer list. What's the point of running a full BitTorrent tracker if it doesn't work with the main P2P system?

EDIT: BitTorrent is incompatible with webtorrent that peertube uses. Peertube also uses HLS instead of webtorrent and behaves a bit different (you can't seed it with a webtorrent client).

Peer discovery:
As I said in 1 and 2 how does the player actually find peers? Is there something like DHT or a tracker built in to peertube? if it's an internal tracker how does the tracker find peers?

EDIT: It uses a tracker build in to peertube.

Thanks for any help.

Testing peertube instance

Since they have come back in stock, I bought a Pi 4 2GB and a Pi 4 4GB. the 2GB model had 2 bent GPIO pins and rattled when shaken, so I opened an RMA request for it. the 4GB model has arrived, and it has small solder blobs on the back of the board (see images)

Is this normal or have I just got unlucky with both Pis? I managed to scrape off solder on the first image but they have left a mark on the board.
The 2GB model seems to be completely working and the 4GB one boots to the bootloader but I'm out of SD cards to test it any further. Should I also RMA the 4GB model or am I being silly here?
Thanks.

Oops! I just nuked my lemmy instance and the other post wasn't in by backups, sorry about that! please don't reply to the other post because I can't see it

Hello, I’m looking for a good first server for a homelab. I do already have an old Dell poweredge 1950 I got for £30 but it’s:

Loud
Draws 350W
Costs too much to run
Only has 2 HDD slots
DRAC card needs Internet explorer

I’m not too bothered by the noise because I can just move it, but the electricity cost is quite ridiculous for something less powerful than my PC in every way. I live in the UK so electricity prices are a huge factor for this.

My Ideal specs are:

~16 cores (total)
>= 128GB RAM
~100W idle power draw
>= 4 3.5" HDD bays
Preferably HBA mode on RAID card
£100-200
2U

Is this completely unreasonable? I have found servers that match this all except the 3.5" bays and 2U. Initially I found a Dell server with 128GB of RAM and two 12 core CPUs for about £200 but I realised it only has 2.5" bays. There is a nice R720 on ebay I am watching but it will probably skyrocket near the end of the bid. Also, it probably draws a lot of power. Any suggestions? do I just need to raise my price? Thanks

Here is my attempt to archive r/homelab before it went dark. Google says there about 92,400 results for site:reddit.com/r/homelab, I have 2098, that's only about 2% of it. Maybe there is something of use to you in that 2%.

Please don't webscrape, if you want all the data you can get the raw BDFR archive at https://archive.douwes.co.uk/reddit/homelab.tar or the live web version at https://archive.douwes.co.uk/reddit/homelab-web.tar
