@bnjmn_marie But is FAST! Very good intelligence vs output speed which absolutely have some good usecases I think

Nemotron 3 Super is not super impressive on benchmarks. Quite far from Qwen3.5 122B Mamba doesn't scale as well as Gated Deltanet? But curious about efficiency. Qwen3.5 overthinks. So maybe it's a good trade off. Also, Nemotron 3 Nano has a tiny KV cache (smaller than Qwen3.5 35B). Maybe this version also uses much less memory than Qwen3.5 122B?
Artificial Analysis@ArtificialAnlys

NVIDIA has released Nemotron 3 Super, a 120B (12B active) open weights reasoning model that scores 36 on the Artificial Analysis Intelligence Index with a hybrid Mamba-Transformer MoE architecture We were given access to this model ahead of launch and evaluated it across intelligence, openness, and inference efficiency. Key takeaways ➤ Combines high openness with strong intelligence: Nemotron 3 Super performs strongly for its size and is substantially more intelligent than any other model with comparable openness ➤ Nemotron 3 Super scored 36 on the Artificial Analysis Intelligence Index, +17 points ahead of the previous Super release and +12 points from Nemotron 3 Nano. Compared to models in a similar size category, this places it ahead of gpt-oss-120b (33), but behind the recently-released Qwen3.5 122B A10B (42). ➤ Focused on efficient intelligence: we found Nemotron 3 Super to have higher intelligence than gpt-oss-120b while enabling ~10% higher throughput per GPU in a simple but realistic load test ➤ Supported today for fast serverless inference: providers including @DeepInfra and @LightningAI are serving this model at launch with speeds of up to 484 tokens per second Model details 📝 Nemotron 3 Super has 120.6B total and 12.7B active parameters, along with a 1 million token context window and hybrid reasoning support. It is published with open weights and a permissive license, alongside open training data and methodology disclosure 📐 The model has several design features enabling efficient inference, including using hybrid Mamba-Transformer and LatentMoE architectures, multi-token prediction, and NVFP4 quantized weights 🎯 NVIDIA pre-trained Nemotron 3 Super in (mostly) NVFP4 precision, but moved to BF16 for post-training. Our evaluation scores use the BF16 weights 🧠 We benchmarked Nemotron 3 Super in its highest-effort reasoning mode ("regular"), the most capable of the model's three inference modes (reasoning-off, low-effort, and regular)

@Dockmyran @patrik_marthin Men okej, vi tar din teoretiska vinterdag istället. Vid -25 är COP normalt runt 2.0, så är det så kallt och elpriset samtidigt går över 340öre/kWh någon 15-minuters slot så kommer du absolut spara några ören den kvarten. Snittpriset i SE1 för vintern 24/25 var 16.5öre/kWh

@Dockmyran @patrik_marthin Jag beskrev inte en teoretisk höstdag, jag beskrev den 5e December hos dig, som var precis den dagen du tog upp i ditt inlägg. Man brukar normalt inte kalla December för höst.

Idag är det –3°C i Västerbotten. Elpriset? 170 öre/kWh. Med andra ord: perfekt dag att tacka sig själv för att ha investerat i två Airrex-dieselvärmare. Testade min 300:a i sommartorpet förra helgen – och det är ingen överdrift att säga att den är galet effektiv. Termostatstyrningen är klockren, värmen jämn, och förbrukningen löjligt låg jämfört med vad elpriserna drar iväg till nu. Rent krasst: Allt över ca 85 öre/kWh gör Airrex billigare än värmepump. Och idag ligger vi på det dubbla. När januari kommer med –25°C och politiken fortsätter som den gör… ja, då kommer elpriset förmodligen att studsa upp snabbare än en socialdemokrat byter åsikt i valrörelsen. Så ja— Känns tryggt att ha backup när elen rusar av ren politisk dårskap. Och framför allt att slippa stå med mössan i hand när ”omställningen” visar sitt rätta pris för vanligt folk. Airrex: ✔ Billigare värme ✔ Stabil drift ✔ Oberoende av elmarknadens cirkus ✔ Gjord för Norrlands vinter, inte för Stockholmspolitik Kanonutveckling faktiskt 🔥😄

@patrik_marthin @Dockmyran Absolut, det är en bra grej. Men nu handlade diskussionen om att TS tror att han sparar pengar på att värma huset med diesel istället för med el.

@kineyDE @popovicu94 The double cache thing is no longer an issue on linux. For all standard I/O ZFS just bypasses the pagecache so a file read from ZFS will be in ARC, not in pagecache, so there is no double caching anymore (except for a few exceptions like mmap I think)

ZFS has some real downsides compared to BTRFS: - useless abstractions / accidental complexity - less flexible storage management - the ZFS ARC is completely retarded for modern OSes like Linux and constantly fights with the pagecache - the license that said it does have some upsides when it comes to performance or stability of higher raid levels

I've had a lot of fun reading about FreeBSD today and I have a question. Is ZFS the greatest filesystem/volume manager ever or what? All the features I've seen today make it sound too good to be true. What are the downsides of ZFS?
Uros Popovic tweet media
Uros Popovic@popovicu94

The BSD journey continues. After the extremely smooth OpenBSD serial install, I tried FreeBSD. The installer was, somehow, even faster. But the real shock wasn't the install speed. It was what I found when I opened the package manager config in /etc/pkg/FreeBSD.conf. This is what I saw: FreeBSD: { url: "pkg+pkg.FreeBSD.org${ABI}/quarterly", mirror_type: "srv", signature_type: "fingerprints", fingerprints: "/usr/share/keys/pkg", enabled: yes } It's... just simple. It's perfectly clear. I can see it uses variables like ${ABI}, which as a perfectly clear meaning, and that I'm on the "quarterly" branch. I instantly understand what's happening. Now, contrast that with my time-tested Debian /etc/apt/sources.list: deb deb.debian.org/debian/ bookworm main contrib non-free ... deb security.debian.org bookworm-security main contrib ... As a first-time reader (or even a 10-year user), what does "bookworm" mean? It's a codename. It tells me nothing about the version, the release, or its support status. I have to go Google it. Then I have to decode what "main," "contrib," "non-free," and "non-free-firmware" all mean relative to each other. The FreeBSD config is transparent. The Debian one requires tribal knowledge. The simplicity is just refreshing. Has the Linux world lost a bit of this over time?

@popovicu94 I use it a lot on Linux, both as root on my laptop and for my backup servers and VM storage I think the few downsides are: -It can be complex to tune correctly for certain workloads -Its slower than non-CoW filesystems such as ext4 and xfs, you trade speed for those cool features

@a_ferron @sebp888 You get the hash when you listen to the handshake between the client and the AP. The hash is a hash of the client and AP MAC address plus a random generated value from each of them (SNounce & ANounce) and the PSK This is all you need to start cracking the hash and figure the PSK

@markusklock @sebp888 OK. How do you extract the hash of the password? I guess if you have the hash you dont even need the handshake. Or the hash you refer to is the MIC HMAC?

A few months ago, I hacked my own wifi password with a simple brute force attack. It was my first time testing the program. My 5-year old RTX 3080 only took 4 hours to crack the 11-digit password: 1 made-up word, 4 numbers, 1 special character. Your passwords, especially wifi, should be at least 18 randomized characters.
