If I understand correctly:

“Ask” is for more open ended questions (The vague “what do you think about” posts like you mentioned). Posts that are asking for a simple / single answer are generally removed for not being open ended. The question is more for discussion.

Here you can ask things that are less open ended and/or are looking for a single or simple answer.

I usually do everything from CLI.

Are you wanting to re-encode it to a different codec or just change the container from mkv to mp4?

To remux the file (change the container format), you can simply do:

# The -f mp4 is technically optional as it can deduce it from the extension, but I like to be explicit
ffmpeg -i file.mkv -f mp4 file.mp4

That should go very fast as it’s just copying the streams as-is into a new container.

If you want to re-encode it to a different codec, then you’ll need to use a more complex ffmpeg command.

Weirdly, back in the dumb phone days, with T9 I could bang out texts way faster and more accurately so long as I wasn’t straying too far out of the dictionary. But it was super easy to add new words, and it would pick them up later.

Similar vibes:

A few years ago I decided to try the lithium-ion UPSs. I’m on my 3rd year with them, and I will never go back to lead acid. I’ve got one “classic” UPS that is still in good shape as long as you don’t try to run more than 100w from it, but when it goes, it goes.

These use the LiFePO4 batteries, and I get close to twice the runtime as my old ones, and they don’t drop from 80% to 10% like lead acids do. The battery chemistry is also good for about 10 years of daily cycling, so assuming the electronics hold out, they seem like they’ll last.

The only hiccup with the model I got is it doesn’t have a serial monitor connection, but you can probably fine plenty that have it.

Nope.

We live in a society, and as far as I’m concerned, stealing the person behind you’s very limited leg room is selfish.

They have a lot of DRM-free options and let you download a clean epub, but like with other stores, it’s up to the publishers whether (and/or when) they can sell them without DRM BS.

I like being able to download the epubs directly so I can put them on my Calibre-web instance and pull them to my Kobo or my phone or whatever I want to read on.

Lol, it really is. It’s how we got the terms “Debbie Downer” and “you’re bumming everyone out”.

What are you honestly tired of people bitching about by this point?

Literally everything.

Half the posts I scroll past are just someone bitching about something. Few people posting about cool stuff, most people posting about rage this or rage that. Or if there is a post about something good, there’s people bitching in the comments how it’s not good enough.

Ugh. It’s like this place wants to be miserable and doesn’t know any other way to exist.

Ugh, yeah. My “temporary” spinners that were an emergency upgrade became permanent when I went to buy the new ones and prices had skyrocketed. I’ve got one cold spare left, so hopefully there’s a price break in the near-ish future

I feel that.

Before I downsized, I was running 3x HP DL360 G6’s with dual Xenons and 96 GB RAM each. Way overkill for my needs but I got them cheap. Unfortunately, they and my air conditioner competed to see who could use the most electricity each month. 😆

The only thing I really lost in the scale down was the ability to spin up dev/test VMs for every little purpose. I’ve mostly just started using Docker containers for things like build environments.

Their Intel graphics work great for transcoding, but yeah, not much else. I’ve got Emby one one of them, and the QuickSync hardware acceleration works well even with multiple simultaneous streams.

Works pretty great as long as you keep your expectations realistic. Easy to upgrade and pretty reliable. Only annoying thing with any of those micro PCs is the cable management is a pain because of the power bricks. I got some USB-C PD adapters and Dell-style cables and that’s made a huge improvement.

About 220W on average with peaks around 280W. I’ve got 8 Optiplex micro PCs, 5 upcycled thin clients running smaller services, fiber ONT, another micro Optiplex as a router, a storage server, main switch, and a 5 port PoE switch for my 4 access points around the house.

Before I downsized everything to the USFF PCs, I was running 3 old enterprise rack servers that were about 220W each.

It’s currently running from solar from about 7am to 4pm with my small solar setup, but I’m in the process of installing a whole house PV system so hopefully will be 24/7 solar powered soon-ish.

Either (voluntarily) 50 years after Earth has been rendered uninhabitable by the upper class who has since moved to Mars or (involuntary) 50 years before that.

I’ve been told that government auctions canbe a good source for cheap used PCs

Can confirm government surplus auctions or sales are a great source for cheap PCs and that they do get snatched up quickly (guilty!) The only other catch is they never come with hard or solid state drives. I’m assuming those just get pulled and destroyed.

I just use the webapp UI and don’t bother with the clients/extensions. Easy enough to just log in, copy/paste from there.

But yeah, the official client (and probably browser extension as well) would probably be forked if/when needed.

I use Vaultwarden

Thanks, and yeah, it’s been fun putting that all together. Unfortunately I’m still learning FreeCAD so they’re not as integrated as I’d like yet, but as soon as I have time to hammer out a design, I hope to have all 3 of these and the UPS/power supply in a nice case.

Yep, running/charging it from solar is why I ended up getting that chonky 18650-based UPS board. It’s the only one I could find that could combine 5V input and battery without dropping out (battery kicks in immediately if solar insufficient and draws the difference between input and output and charges and powers simultaneously otherwise).

Thanks!

What are the use cases for taking it with you instead of just connecting to your homelab?

I built it just to see how much I could cram onto a Pi Zero clone/how many self-hosted services I could have on something I can fit on my keychain, and the answer was “a lot”. It’s something of a travel server, travel router, emergency backup server, etc.

I mainly just wanted a subset of my homelab services available in something I could take with me anywhere. Home lab could go down while away, power could go out, something to use while glamping, can take it with me if there’s ever an emergency where I have to evacuate, etc.

What started out as a single unit has become a three unit portable stack lol. Yay feature creep!

Services

• Jellyfin (all content pre-transcoded so everything can direct stream)
• CodeServer (setup for Python, NodeJS/Bun + React, and Platform.IO for ESP8266/ESP32 development)
• Kiwix (including the full Wikipedia dump with images as well as offline docs for lots of code libraries I work with, etc)
• SearxNG so I always have a sane search engine available
• CalibreWeb with my whole ebook library
• MPD+Snapcast+My whole music library. Also has myMPD web UI for controlling MPD. Snapcast clients can connect, and it can serve multi-speaker/multi-room audio
• PiHole serving both ad blocking and local DNS as well as providing DHCP for the access point
• PairDrop for sending/receiving files
• NodeRED and Mosquitto MQTT for setting up ad-hoc automations
• Nginx with real LetsEncrypt certs so all services have valid SSL certs and hostnames

Networking

• One USB port is configured in ethernet gadget mode. Can plug it into a host PC and get an IP address from it
• One wifi adapter is setup as an AP and is bridged with the USB ethernet (a PC plugged in and a wifi client are on the same L2 plane).
• The second wifi is the “WAN” connection if one is available. Can alternatively connect to USB tethering on my phone
• If there is any kind of “WAN” upstream, the LAN bridge (USB ethernet/Wifi) will route to it
• Wireguard to connect back to my homelab.

File Services

• Samba
• Encrypted LUKS volume for critical docs (tax records, vet records for the dogs, etc)

I’ve got a second unit that connects as a client to the main one with some additional backup services:

• Email stack( Dovecot, Postfix, SpamAssassin, ClamAV, Webmail)
• Matrix/Synapse stack
• Asterisk
• Snapcast client

The second one is basically a backup to my main stack in case of disaster/power outage/etc. Those all tunnel to a cloud VPS + load balancer and only need an internet connection to setup the tunnels to receive traffic from the VPS (and route back out to it). Those services are stopped and a cron task keeps them in sync with the main ones in my homelab. If I need to fail over, I just SSH into the VPS and re-route traffic to them instead of my homelab endpoints.

I self-host my own email and chat and phone services, so those have become critical services I want to always have online. Essentially these little Pi clones are a backup stack for my most used services and one that is both extremely low power and portable should I ever need to host them on the go (house burns down, have to evacuate due to emergency, etc).

Third Unit (Still on the bench)

I have a third unit that’s built on a PiZero2W but it’s still on the workbench (but functional!). Just haven’t gotten any kind of case at all built for it.

It’s got two RTL-SDR units attached. One is tuned to the NOAA weather radio station and feeds into Snapserver on the main unit (so you can listen to the weather radio anywhere on the network) as well as piped into Meshtastic EAS-SANE alerter in order to forward emergency alerts to Meshtastic. There’s a USB-connected Meshtastic node attached as well for that.

The second RTL-SDR is setup as a generic FM radio tuned to the local variety station. It’s just piped to Snapserver on the main unit to make it available on the network.

I may convert the second SDR into a ADS-B listener, but for now, I like having the FM radio available.
