    I'd say recreating an existing website as is, is the easier task. Doing a look alike, even if the models do take some shortcuts on the way is doable right now. You have a template …

    My recommendation if you are willing to push it further is to keep KV and always needed weights pinned in memory, so they do not get evicted. This is likely already the case, as th…

    Not sure if mmapping is the right way. In my own tests I noticed that simple mmapping will produce many small reads and not keep the SSD queue saturated. So if RAM is large enough …

    I have prototyped something similar with ollama some months ago. Do you mmap or issue reads on demand? Also do you use io_uring to interleave compute with io or do you spawn extra …

    IO is very bursty in these setups. When the router results are in you can start loading experts from SSD. In this brief moment the SSD is saturated. Outside of that the SSD is idli…

    Does an SSD meaningfully degrade by read only workloads?

    Not only you understanding the how, but you not understanding the goal. I often use AI successfully, but in a few cases I had, it was bad. That was when I didn't even know the end …

    I also tried myself, on different array sizes, with more iterations. The branchy version is not strictly worse. https://gist.github.com/Stefan-JLU/3925c6a73836ce841860b55c8...

    They are explicitly not assuming anything about the content of the auxiliary space (full hard drive). So the data might be incompressible and thus compressing it and restoring it a…

    So the trick is to do the computation forwards, but take care to only use reversible operations, store the result outside of the auxiliary "full" memory and then run the computatio…

    I'm not sure that the analogy stretches so far. What even is an artificial neuron in an Artificial Neural Network executed on "normal" (non-neuromorphic) hardware? It is a set of w…

    I think it is a little unusual, but nothing unheard of. I started as a junior IT Consultant in Hamburg, Germany with a 3 month notice, but could only quit every half year. So for q…

    This looks like german to me, but i haven't ever seen these words used together. I thought it might be some old german and googled it, but searching "bewunderungeifersucht" just yi…

    Just started to copycat your code to rust, not yet finished, continuing tomorrow https://github.com/Roxxik/ping_ether/blob/master/src/main.rs

    Just today I started to look into RLPx to do some basic network discovery, so your guide is quite nice to have as a reference. But I had some difficulties getting started, because …

    It shouldn't be that difficult to write some simple compiler to translate a scripty language that looks like awk to BPF-Assembly (or C and stuff that into LLVM). I might look into …

    I was just thinking about writing a minimal traffic-analyzer and libpnet looks way more suitable for this task than libpcap. And adding the functionality for a pcap like fileformat…
