  • can you pls explain what you mean in more depth?

    your original post is sufficiently vague that tbh i don’t blame people for assuming you were just bootlicking? [which probably says more about the state of the world than you as an individual, but honestly it’s not clear what you’re trying to say?]

    we all know a random citizen/local business presenting an identical calibre of evidence of repeated crimes would be extremely unlikely to routinely receive this degree of resource allocation.

    so if it’s an idealised aspirational universal “order” you’re talking about then obviously noone’s buying it - and i don’t think you are either. so what do you mean?


  • tar pits target the scrapers.

    were you talking also about poisoning the training data?

    two distinct (but imo highly worthwhile) things

    tar pits are a bit like turning the tap off (or to a useless trickle). fortunately it’s well understood how to do it efficiently and it’s difficult to counter.

    poisoning is a whole other thing. i’d imagine if nothing comes out of the tap the poison is unlikely to prove effective. there could perhaps be some clever ways to combine poisoning with tarpits in series, but in general they’d be deployed separately or at least in parallel.

    bear in mind to meaningfully deploy a tar pit against scrapers you usually need some permissions on the server, it may not help too much for this exact problem in the article (except for some short term fuckery perhaps). poisoning this problem otoh is probably important



  • ganymede@lemmy.mltoPrivacy@lemmy.mlIs Signal messaging really private?

    Imo signal protocol is mostly fairly robust, signal service itself is about the best middle ground available to get the general public off bigtech slop.

    It compares favorably against whatsapp while providing comparable UX/onboarding/rendevous, which is pretty essential to get your non-tech friends/family out of meta’s evil clutches.

    Just the sheer number of people signal’s helped to protect from eg. meta, you gotta give praise for that.

    It is lacking in core features which would bring it to the next level of privacy, anonymity and safety. But it’s not exactly trivial to provide ALL of the above in one package while retaining accessibility to the general public.

    Personally, I’d be happier if signal began to offer these additional features as options, maybe behind a consent checkbox like “yes i know what i’m doing (if someone asked you to enable this mode & you’re only doing it because they told you to, STOP NOW -> ok -> NO REALLY, STOP NOW IF YOU ARE BEING ASKED TO ENABLE THIS BY ANYONE -> ok -> alright, here ya go…)”.







  • (ok i see, you’re using the term CPU colloquially to refer to the processor. i know you obviously know the difference & that’s what you meant - i just mention the distinction for others who may not be aware.)

    ultimately op may not require exact monitoring, since they compared it to standard system monitors etc, which are ofc approximate as well. so the tools as listed by Eager Eagle in this comment may be sufficient for the general use described by op?

    eg. these, screenshots looks pretty close to what i imagined op meant

    now onto your very cool idea of substantially improving the temporal resolution of measuring memory bandwidth…you’ve got me very interested with your idea :)

    my inital sense is counting completed L3/4 cache misses sourced from DRAM and similar events might be alot easier - though as you point out that will inevitably accumulate event counts within a given time interval rather than an individual event.

    i understand the role of parity bits in ECC memory, but i didn’t quite understand how & which ECC fields you would access, and how/where you would store those results with improved temporal resolution compared to event counts?

    would love to hear what your setup would look like? :) which ECC-specific masks would you monitor? where/how would you store/process such high resolution results without impacting the measurement itself?





  • edit: nvm i re-read what you wrote

    i agree it does mostly fulfill the criteria for libre software. perhaps not in every way to the same spirit as other projects, but that is indeed a separate discussion.
