Hotend termistor reports -51°C at ambient temperature

Hi,

I replaced the heating element to my SV08 nozzle, reinstalled it and now the thermistor reports -51°C at ambient temperature (resistance is around 70kOhm): is it dead or it's just a configuration issue?

EDIT: looks like it's a loose connection of the thermistor to the toolboard or the connector on the toolboard is giving up... I'll try and see if i can somewhat make it so that the contact is stable.

Se la Russia attaccasse i paesi baltici (per esempio) sareste disposti ad andare in guerra per difenderli?

Il titolo dice (quasi) tutto: se la Russia attaccasse qualche paese europeo lontano dall'Italia, sareste disposti ad entrare in un'economia di guerra con tasse per sostenere la guerra, magari razionamenti su carburanti o altri beni, lavorare per industrie belliche o anche essere arruolati nell'esercito e andare al fronte?

Grub not booting

Long time Linux user, I'm trying CachyOS now and for now I'm happy with it... except that the grub boot doesn't quite work.

When I boot the system I'm dropped into the grub shell, then if I set root=(hd0,6) and normal it brings up the grub menu and I can boot into the system.

I looked into /etc/default/grub and everything seems fine to me, tried grub-mkconfig -o /boot/grub/grub.cfg and also grub-install but still doesn't work... what should I check?

Help configuring bridge network (for VM)

Hi,

I have an issue with the network settings on my home server: I run VMs on it and I managed to setup the bridge, issue is is that when I change something in the system the network name changes from enp5s0 to enp7s0 to enp8s0, which leads to then network not going up. And since it's an headless system this is a royal PITA.

System is Debian 13.

/etc/network/interfaces just loads files from /etc/network/interfaces.d

~$ ls /etc/network/interfaces.d/
br0  enp5s0  enp7s0
~$ cat /etc/network/interfaces.d/enp5s0 
#auto enp5s0
#iface enp5s0 inet manual
~$ cat /etc/network/interfaces.d/enp7s0 
#auto enp7s0
#iface enp7s0 inet manual
~$ cat /etc/network/interfaces.d/br0 
auto br0
iface br0 inet dhcp
  bridge_ports enp5s0 enp7s0 enp6s0
~$ LC_ALL=C nmcli --overview

        servers: fe80::32cc:21ff:fe33:9ab3
        interface: enp8s0

I know, the setup is ugly but this is the only way I got it working.

I tried using networ-kmanager to create the bridge but it didn't work, also I couldn't geti it to stop interfering and still having a working network.

Any help or detailed (and working!) guides on how to setup a bridge for VMs so that they're transparently seen as on the same LAN network will be greatly appreciated.

How do I use MTP?

Hi,

I'm trying to use MTP with llama.cpp, I built from source the mtp-pr, download an MTP model from huggingface https://huggingface.co/unsloth/Qwen3.6-27B-GGUF-MTP/resolve/main/Qwen3.6-27B-Q6_K.gguf

But when I run the model I have an error:

error while handling argument "--spec-type": unknown speculative decoding type without draft model

Can someone tell me what I'm doing wrong?

SOLVED: I used the wrong build command, thanks for you help :)

Valore di vecchie case fuori mercato

Non so se è più una domanda o una riflessione... ma diciamo che una casa o un appartamento da ristrutturare in una certa zona vale 800 euro/mq.

Con il costo di ristrutturazione di 1000E/mq (come minimo) per assurdo chi vende dovrebbe pagare chi compra, o quantomeno vendere la casa per pochissimo... se voi doveste vendere una casa o appartamento del genere come vi regolate? Fate comunque un prezzo "alto" senza contare i prezzi di ristrutturazione e piuttosto che svendere vi tenete l'immobile?

Se invece volete comprare uno di questi immobili ma il prezzo è decisamente troppo alto che fate, proponete una cifra sensibilmente inferiore che però vi sembra ragionevole o lasciate perdere?

In my current workflow (coding in python/c++ and technical reports) I mostly use Qwen3.6 27B and Gemma4 31B. In the past I tried other models like Deepseek with decent results but was painfully slow.... so do you think there is some model that I'm missing and should try?

EDIT: to be clear, I'm not asking how to make those models run faster, I'm asking which other models I should try. Telling me to try them all doesn't help, first because there are a bazillion models available and nobody on earth could reasonably try them all, and second if I were willing to try them all I wouldn't have asked here. If I see the model using more VRAM than avalilable I already scale down, either on the quantization or on the model itself if possible, or I abandon the model because it's too slow.

System specs: MI50 32GB + V100 32GB. And going below 10tps on real world usage is "painfully slow".
