What are max print speed and volumetric set to?
For some filaments (silk PLA) I’ve had to slow things down (120mm/s max print speed and 10mm3/s max volumetric speed) or it comes out horrible. Only used 0.4 nozzles so far though.
- Comment on EmuDeck team announce Linux-powered EmuDeck Machines 2 months ago:
I’ve bought a few Gmktek Intel N97 mini-pcs on Amazon (US) for around $200 usually. So far I’ve only used them for htpc @ 1080p but N97 GPU has a higher boost than N100 GPU so I imagine should do alright for lots of emulators too.
- Comment on EmuDeck team announce Linux-powered EmuDeck Machines 2 months ago:
Their project timeline being really short combined with a really low “flexible goal” of $69,780 doesn’t give me a lot of confidence in it releasing or shipping on time if it ever does.

Hot Wheels has Marvel series of cars too and took picture of this “well known” one recently.
- Comment on Linux Distro for Jellyfin HTPC 6 months ago:
I’d recommend using distro you know best and/or most prefer to work with. I use the flatpak install of Jellyfin Media Player but there are also deb files available.
I’m currently using minipc with Intel n5105 (or something similar) for 1080p HTPC. Debian 12 OS with auto-login & Jellyfin Media Player starting at login. I control it with pepper jobs RF remote but also have a logitech wireless keyboard+touchpad for it. Keyboard+touchpad come in handy when browsing media sites on firefox but some might restrict quality. Some of the newer minipc’s I tried required adding backports repo to install newer kernel for wifi to work. I had been playing with Debian a lot when I set up first one & been using clonezilla to image them so it’s stuck.
Ordered a gmtek n97 minipc to play with and should have it in about a week. Going to test it out with 4k but it’s not a deal breaker for me if it cannot handle that well enough.
- Comment on Looking for MiTV box replacement 6 months ago:
Yep, asking for something I’m sure a lot of us would love to have, a ready to go TV remote control style usage, but rather than having discussions about why those options aren’t viable just downvoting.
- Comment on Any way to update the software in Raspian without updating the OS? 6 months ago:
Create a backup image from the working SD card. Write that backup image to a spare SD card and verify it works. Then try to do ‘apt update’ and see if anything breaks. If it breaks you got a spare SD card ready to go :)
- Comment on Local DNS-01 wildcard certificate not renewed? 8 months ago:
I had issues with DNS checks and traced it to my pihole. I changed that container’s resolv.conf to use cloudflare DNS and it has been working fine since. It was with Caddy so needed to change over to use IPs.
- Comment on Do you run a private CA? Could you tell me about your certificate setup if you do? 11 months ago:
Self-host your own ACME server. Then you can use certbot pointed there.
These instructions are old so not sure if newer/better ways, blog.sean-wright.com/self-host-acme-server/
- Comment on YouTube just made it harder to avoid ads with a tiny skip button 11 months ago:
They still build recommendations even if you’re not logged in, you can see them in the sidebar after you load a video. Imo they only removed them from the homepage to try convincing people to log in or create account, it’s all about increasing user numbers, ad engagement, and data collection these days.
- Comment on Docker or Podman for Jellyfin? 11 months ago:
The container method used should be whatever you are more familiar with or prefer. They both have their own quirks, pros, & cons.
SELinux - If you don’t want to deal with SELinux then set it to permissive mode. If you want to keep in enforcing mode you need to create the appropriate policies, …redhat.com/…/configuring-selinux-for-application…
Firewall - If you don’t want it’s protection then look up instructions to stop & disable it on your distro.
Port forwarding - From linux container side you either need to specify host networking or the ports you want to allow through, there is no avoiding that if it needs to be network accessible. If you want it internet accessible then you need to setup port forwarding on your router.
Have you looked into something like yunohost? It may be the kind of thing you’re looking for.
- Comment on Chromecast over Tailscale? 11 months ago:
For 3, if router supports it could also try doing static route via Tailscale joined machine that has IP forwarding enabled
- Comment on Chromecast over Tailscale? 11 months ago:
If your router lets you try adding a static route for the tailscale IP/subnet to the laptop with IP forwarding enabled.
- Comment on Are there capture cards with such low latency you can use them to game through a computer? 11 months ago:
Yep, I only played through couple races & was a few beers in, it felt acceptable for me at the time. Not sure how it would be with the latest gen Elgato cards & they are pricey so best to buy from store with a good return policy.
- Comment on Are there capture cards with such low latency you can use them to game through a computer? 11 months ago:
I have never seen a capture device with USB interface have any kind of usable latency, you’ll want one with PCI Express interface.
Elgato makes a capture card with PCI Express interface, I had a friend who used one to play all of his consoles on big virtual screen in VR. I tried out Mario Kart 8 for the Switch and it played great.
- Comment on How I accidentally wiped my server by having a typo in my Nextcloud docker config 1 year ago:
Was it the official container image or 3rd party? Whichever it was, they should get notified so that init script can get fixed to prevent similar happening to others.
- Comment on SteamOS will be coming to other handhelds before you can install it on your PC 'because right now, it's very, very tuned for Steam Deck' | PC Gamer 1 year ago:
Would love a new Steam Machine and could actually be good this time. Proton didn’t exist when they released the original Steam Machines which limited you to linux ports of games. I had bought two but wiped & did clean installs of Windows 7 so we could play all the games wanted to.
Before Proton, gaming on linux relied on native ports or WINE. Native ports were rare & not always better. WINE took some learning to make work well but I dunno, never got any good at it.
- Comment on SteamOS will be coming to other handhelds before you can install it on your PC 'because right now, it's very, very tuned for Steam Deck' | PC Gamer 1 year ago:
The OS was also very limited with focus on Linux ports of games which there were not very many at the time. Proton wasn’t a thing yet. I bought two of them, one for myself and one for my brother. I tested it out & it was neat but wiped both to do clean installs of Windows 7 so could play the games we wanted.
- Comment on Is this a bad option for a home server? 1 year ago:
Intel Quick Sync video saw a lot of improvements on 8th gen & since it’s all so old the pricing differences between 7th & 8th gen are going to be negligible.
- Comment on Is this a bad option for a home server? 1 year ago:
Yep, 8th gen (Coffee Lake) saw a lot of improvements in Intel Quick Sync, en.wikipedia.org/wiki/Intel_Quick_Sync_Video#Hard…
- Comment on NFS or iSCSI? 1 year ago:
For the sata drive behavior it’s probably it finishing the writes from buffer. I like to use the iotop utility to watch storage IO activity on my systems. Could try running it on both systems to get a better picture of what’s going on.
I currently use NFS and CIFS but have used iSCSI in the past. I like the simplicity of NFS & CIFS and they meet my uses. iSCSI has it’s strengths as others have stated.
- /var/lib/mysql - I would say iSCSI in it’s own image+lun. Should get lower latency as well as higher transfer rates compared to NFS for DB but it depends on the kinds & how much usage.
- virtual machine images - I prefer NFS mounts for same reason, easier to work with the files directly. If you do go with iSCSI you can have different disk images for different kinds of VMs. Should be able to use both at same time on most hypervisors if you want to play with them too.
- lots of small files - NFS should work without issue
- Comment on Docker vs Podman, which one to choose for a beginner and why ? 1 year ago:
Nothing to stop running podman containers with full root access by creating & running them as root, you run them as whatever user you want. I’ve done it to troubleshoot containers on more than one occasion, usually when I want to play with VPN or privileged ports but too lazy to do it proper. The end goal for a lot of ppl, including myself, is to run as many things as non-root as possible. Why? Best practices around security have you give a service the minimal access & resources it needs to do it’s tasks. Some people allow traffic from the internet to their containers & they probably feel a little bit safer running those programs as non-root since it can create an extra layer that may need to be broken to fully compromise a system.
- Comment on Questions about blade server SSDs 1 year ago:
Sounds like the drives are combined with RAID 5. Could be hardware RAID card or software RAID as part of the BIOS. Server model number can be used to search for administrator manual and may have more info there. If it’s hardware RAID card then try to find the model number & search for it’s manual. If it’s software raid at the BIOS level then motherboard/server manual will cover it. Should be some messages and prompts during boot related to it. Terms to look for ‘RAID’, ‘storage controller’, ‘Perc’, ‘LSI’.
- Comment on Sustainable network upgrade 1 year ago:
Most standalone APs can be plugged into the router and immediately start working, they’ll forward along DHCP requests. You can turn off your router’s wifi after they have been configured. For Unifi APs you only need the controller running when you want to manage/update the APs and for stats collection, I only power mine up to check for new firmware updates once a month. Can disable Unifi analytics/telemetry with a config file option too but no way to do it via web UI.
For VLANs you will need to configure the VLANs on Opnsense and the APs. Unifi lets you specify the mgmt VLAN and VLAN per SSID. For my setup I have vlan 5 for work ssid, 10 for mobile devices, 15 for IoT and other things that don’t need internet, and 20 for a couple temporary & guest SSIDs.
The Unifi APs are alright but the controller software itself is fairly limited for stats/data, still better than other standard consumer APs I’ve used though. I’ve been wanting to try out Grandstream Wifi APs for replacement as most models include a built-in controller capable of managing more than enough APs for my home uses and still have option of standalone controller or cloud managed but it’s not priority as my current APs still receive firmware updates,
- Comment on Jellyfin on Proxmox 1 year ago:
Another benefit to LXC is you can map devices, including GPU, to multiple LXC while keeping them accessible to the host. For my home setup I currently have 3 LXC with access to the iGPU, 1 for jellyfin+caddy via podman nested, 1 for moonfire-nvr via podman nested, and been trying to use 1 to figure out hardware transcoding with owncast through multiple install methods but no luck so far. I’ve also been playing with mapping rtl-sdr v3 devices, zigbee stick, zwave stick, and coral usb for a variety of projects lately.
- Comment on Add HTPC capabilities to home server 1 year ago:
On proxmox you should be able to share any GPU (integrated or dedicated) to multiple LXCs while keeping it accessible to the host. I use intel integrated GPU in LXC for plex, jellyfin, and one with just ffmpeg I use to convert videos occasionally. I used these instructions as starting point/base when I set mine up on proxmox v7.x, …proxmox.com/…/plex-hw-transcoding-lxc-and-jasper…
I had looked at instructions to assign the GPU to a specific VM but it looked like way too much work and people were saying it didn’t always work for the 11th gen iGPUs. Thankfully I ran across the sharing method and it’s been running stable since.
- Comment on Router for multigig internet 1 year ago:
My info may be outdated as I last had G Fiber about a year ago but have moved out of their service area :(
When I first got the 2G down/1G up G Fiber service there was no bridge mode & had to use their provided device as modem+router+wifi. They updated it to add in a bridge mode option but I never tested it. I had dropped back down to 1G down & up before that options was available.
- Comment on Selfhosted backup solution with GUI 1 year ago:
My last NAS & ESXi box were 12 years old when I retired them. I had thought about sticking with used enterprise gear but wanted a break to be a little lazy for a couple years. Storage is on Synology (DS1520+) and Proxmox runs on Asus PN63-S1 mini PC. Hyper Backup was primary reason I chose Synology (always been lazy about off-site backups) and docker feature has come in handy for things like secondary pihole & DNS. LXC with docker or podman have been able to cover majority of my needs in proxmox but still have Home Assistant & Unifi Network Controller on their own VMs. Home Assistant I have zero plans to move. Unifi I eventually plan to move over to docker but it works for now, albeit on an older version. Really need to up my documentation & diagram game, it’s all a huge mess, lol.
Future plans would love to have closet full of used enterprise servers running proxmox with all flash ceph storage backend then can do whatever NAS distro I want as a VM. My budget is focused elsewhere for next year or two unfortunately so gonna be awhile unless something breaks.
Always like to hear about other setups as I am constantly re-thinking my own.
- Comment on Certificate management 1 year ago:
You can self-host ACME server which lets you use certbot to do automatic renewals even for private, internal only certs. I don’t know if it would work with NPM. I plan to test that out at some point in the future but my current setup works & I’m not ready to break it for a maybe yet :P
- Comment on Certificate management 1 year ago:
I use Caddy with the Cloudflare DNS plugin for Let’s Encrypt DNS based challenges, should work for wildcard too but only have a couple subdomains so never tried to do that. My DNS entries are public but point at private IP ranges, e.g. nc.PRIVATEDOMAIN.COM resolves to 192.168.1.20 where Caddy sends the traffic to my Nextcloud docker
