I will try to cross-post some of my baking pictures here to try and lively up this community :)

Hello everyone, first time poster on this community!

I think the context came out a tad too long, so TL;DR: this is gluten (and nickel) free bread made mostly from rice flour and starch. The recipe is my own, developed mostly from scratch for the past year or so. The starter is live, 2.5 years old, made from whole grain rice flour (more photos and info below).

A bit of context: For a variety of reasons and food allergies/intolerances I've been eating gluten free for the past 5 years or thereabouts. I've always been deeply unsatisfied with commercial gluten free breads, especially since my mother used to bake a lot, even sourdough sometimes, and it was always stellar.

In an attempt to make some decent bread, a couple years ago I started my live sourdough made from whole grain rice fluor exclusively (it actually started from white rice flour, but whole grain has more proteins, so it rises better, and I find it has a better taste too).

The recipe is one I've been developing on my own for the past year or so, mostly because I needed something that was also nickel free (for allergies). I live in Italy and the GF offer here is stellar, but the only alternative I could find which suited my needs tasted waaay too sugary for my taste (which is a common issue in gf baked products I find, since sugar tends to be used both for rising and for giving the bread a nice caramelized color). GF products tend to replace wheat with mostly corn (tons of nickel) and/or potato starch (also tons of histamine as well, and I need to keep it in check). The flour mix I was using before was made mostly from those two alone, so I had to change it.

This is my first bake after a period away from home. I had dried and freezed my starter before leaving, then unfreezed it and started feeding it again a couple days before the bake. I actually got the proportions for my recipe completely wrong this time, and added about 100g too much flour. Somehow the proportions worked out in the end, I didn't even need to change the hydratation.

After making the dough, I let it rise for ~1.5hrs outside the fridge (~35°), then 12hrs in the fridge, then a couple hours outside to let it reach room temp. I think the dough was a bit dry on the outside and it split during rising. I cut it ~1cm deep in a ) shape along the border before baking. With my recipe the bread usually splits along the cut which didn't happen this time, but at a second look it mostly rised from the previous split.

The crust is very crunchy for a GF bread, not so much for a norml wheat bread. The crumb is a bit humid and gummy, probably because of too high hydratation. The bubbles are some of the best I've even obtained, I'm definitely marking this accident as a happy one.

Would be really happy to contribute my bakes to this community and to hear everyone's thoughts!

Hello everyone, I'm building a new server for the house, it will act as a NAS for everyone and host a few services like paperless, immich, baikal, jellyfin, syncthing probably navidrone, etc. The main reason I'm building a new one is that my current one is a HP prebuilt with a 3rd gen i5 and 8GB ram that is slowly beating the bucket, my 4TB HDD is completely full and there's no more sata ports nor space in the case.

I am fully psychologically prepared to be 24/7 tech support, but after all I already am, and in this way I have to support services for which I know how they work (and that I trust!) and not some strange Big Tech service whose UI and inner workings changes every other day.

For reference my new build is:

• CPU: Ryzen 5 PRO 4560G + stock cooler. Has integrated graphics, can use it for Jellyfin transcoding.
• RAM: Corsair Vengeance 2x8GB (from my desktop before I upgraded to 64GB RAM. If needed in the future I will upgrade the capacity and probably switch to ECC, I've chosen the CPU since it has support for it)
• SSD NVME (boot+VM storage): Verbatim VI3000 512GB
• Storage (SATA): 4x12TB Seagate Enterprise (White label) to use ZFS and Raid Z1 + 1x512GB Samsung SSD as cache.

I'm planning on using proxmox on bare metal and spin up VM/containers as needed, for which I'm wondering:

• I know proxmox can manage ZFS arrays, is it better to create the array via proxmox, then share it as needed via something like openmediavault in vm/container OR to create a TrueNAS VM and passthrough the SATA controller to it, then manage everything via TrueNAS? I've done the latter in the past on another server, it's holding strong

• I don't know if exposing the server to the open internet is a good idea (of course with fail2ban and a firewall properly configured) or to just keep a VPN connection to the server always open. I think the latter would be more secure, but also less user-friendly for parts of the family. I'm using wireguard currently to remote into my server when needed, and sometimes networks like eduroam in my university block it completely.

  • Self signed SSL certificates might also be a problem in the latter case

• Since I will experiment with this server a little bit, I was thinking of keeping:

  • One VM for services for the family (exposed to internet or VPN)
  • One VM for services I still want to expose (I currently expose a couple websites for friends with data archived in my NAS)
  • One VM for me to experiment with before going in "production" for the family

Each VM would host its services using Docker+Portainer. My question is: is this too convoluted? Should I just use proxmox's LXC containers (which I have no experience with) and host services there?

I was also thinking of spinning up a pfsense/opnsense box and put the server into a separate VLAN from the domestic lan. But that will be a project for a second time. Unfortunately the way ethernet is wired in my house and for the physical space I have available prevent me from separating the networks by physically using another router.

Thanks!

Hello everyone, I need some advice.

I am making custom PCBs for a project of mine. It's basically for a little remotely controlled robot using little DC motors. I chose the Seeed Studio XIAO ESP32C3 as the uC since it has inbuilt wifi/bt, 3.3V regulator that I can use to power the motors (can source up to 700mA) and lipo charging management (the robots will run on battery). As you can see from here, the microcontroller is surface mounted and the pads for the battery are on the bottom layer. Same story goes for the thermal pad of the microcontroller and the thermal pad of the motor driver (datasheet). I have worked with SMD components in the past and can solder them by hand, but I have never worked with SMD components that have thermal pads on the bottom layer. My question is: how to manage (route?) them? My PCB is 2-layer and I was planning on having both layers filled with a ground plane. Do I just connect thermal pads to the ground plane and call it a day? Wouldn't that make the components hard to solder with hot air? Do I make an isolated polygon that only acts as a thermal pad?

Speaking of soldering is even hot air the way to go in this case? My PCB has components on both sides, and I was planning on ordering stencils together with the boards and using solder paste, placing the components and then using hot air to solder the components in place. I thought a hot plate would be better but I don't have access to one and I don't know how that works with components on both sides.

I attached some photos of the PCB in Kicad, and here's the git repo. If it is of any help, I'm planning of having them manifactured by JLCPCB. It is also my first time using KiCad, so go easy on me :)

Thanks!
