<p>If this wasn't CERN tech I would think I was being taken for a ride. Conventional wisdom is that distributed consensus is not possible at this kind of performance, does anyone have a sense for how this is different and how my mental model is wrong?</p>

<p>Thanks. I thought it was interesting choosing arithmetic instead of some other relation because multimodal arithmetic (via CLP) is more of a PhD thesis than a blog post. Other relations might've been easier to demonstrate a general query.<p>What I couldn't tell from the article was if the author somehow achieved a multimodal arithmetic relation without needing CLP using a stack machine. That would be a neat technique.</p>

<p>Man that is such a bummer. The Naval Support Activity (NSA) "base" is not a hardened military facility. I've never been to the one in Bahrain, but it's usually where you go to play ultimate frisbee, maybe some paintball if you are lucky, and other types of R&R. Usually have a Naval Exchange (NEX) which is like a really discounted 7-11 / gift shop / walmart (depending on where you are).</p>

<p>Yeah, this checks out. I wonder what they are doing to prevent semantic collapse.   Also, I wonder if the base model would already be instruct and RLHF tuned or only pre-trained. Trying to do additional training without semantic collapse in a way that is meaningful would be interesting to understand. Presumably they are using adapters but I've never had much luck in stacking adapters.<p>i.e.:<p>1. Do I start with an RLHF tuned model, "pretrain" on top of that (with adapter or by freezing weights?), then SFT on top of that (stack another adapter, or add layer(s) and freeze weights?) (and where did I get the dataset? synthetic extraction from corpus?), then RL (adapter, add layer(s) and freeze?)<p>2. or do I start at SF tuned model, ...<p>3. or do I start at raw pre-trained model, ...<p>Would love to know what the matrix used was.</p>

<p>> Pre-training allows organizations to build domain-aware models by learning from large internal datasets.<p>> Post-training methods allow teams to refine model behavior for specific tasks and environments.<p>How do you suppose this works? They say "pretraining" but I'm certain that the amount of clean data available in proper dataset format is not nearly enough to make a "foundation model". Do you suppose what they are calling "pretraining" is actually SFT and then "post-training" is ... more SFT?<p>There's no way they mean "start from scratch". Maybe they do something like generate a heckin bunch of synthetic data seeded from company data using one of their SOA models -- which is basically equivalent to low resolution distillation, I would imagine. Hmm.</p>

<p>In Prolog the syntax is incredibly important. It is designed to be metainterpreted with the same ease in which a for-loop might be written in another language.<p><a href="https://www.metalevel.at/acomip/" rel="nofollow">https://www.metalevel.at/acomip/</a><p><pre><code>  mi1(true).
  mi1((A,B)) :-
        mi1(A),
        mi1(B).
  mi1(Goal) :-
        Goal \= true,
        Goal \= (_,_),
        clause(Goal, Body),
        mi1(Body).
</code></pre>
This can be arbitrarily extended in very interesting, beautiful, and powerful ways. This is extraordinarily hard to achieve and did not happen by accident.<p>As a challenge, see how easy it is to write a metainterpreter in another language of your choice. Alternately, see if you can think of any way the metainterpretation system in Prolog could be improved.<p>Finally, think of what would happen to this if we changed the syntax and introduced something like object.field notation.<p>So while logical programming can be achieved with other syntaxes, the metaintrepretive aspect will be lost. I have yet to see a language that does this better.</p>

<p>So I have been doing formal specification with TLA+ using AI assistance and it has been very helpful AFTER I REALIZED that quite often it was proving things that were either trivial or irrelevant to the problem at hand (and not the problem itself), but difficult to detect at a high level.<p>I realize formal verification with lean is a slightly different game but if anyone here has any insight, I tend to be extremely nervous about a confidently presented AI "proof" because I am sure that the proof is proving whatever it is proving, but it's still very hard for me to be confident that it is proving what I need it to prove.<p>Before the dog piling starts, I'm talking specifically about distributed systems scenarios where it is just not possible for a human to think through all the combinatorics of the liveness and safety properties without proof assistance.<p>I'm open to being wrong on this, but I think the skill of writing a proof and understanding the proof is different than being sure it <i>actually</i> proves for all the guarantees you have in mind.<p>I feel like closing this gap is make it or break it for using AI augmented proof assistance.</p>

<p>Author: "Not my favorite language"<p>Prolog: "Mistakes were made"<p>As an avid Prolog fan, I would have to agree with a lot of Mr. Wayne's comments!  There are some things about the language that are now part of the ISO standard that are a bit unergonomic.<p>On the other hand, you don't <i>have</i> to write Prolog like that! The only shame is that there are 10x more examples (at least) of bad Prolog on the internet than good Prolog.<p>If you want to see some really beautiful stuff, check out Power of Prolog[1] (which Mr. Wayne courteously links to in his article!)<p>If you are really wondering <i>why Prolog</i>, the thing about it that makes it special among all languages is <i>metainterpretation</i>.  No, seriously, would strongly recommend you check it out[2]<p>This is all that it takes to write a metainterpreter in Prolog:<p><pre><code>  mi1(true).
  mi1((A,B)) :-
          mi1(A),
          mi1(B).
  mi1(Goal) :-
          Goal \= true,
          Goal \= (_,_),
          clause(Goal, Body),
          mi1(Body).
</code></pre>
Writing your own Prolog-like language in Prolog is nearly as fundamental as for-loops in other language.<p>[1] <a href="https://www.youtube.com/@ThePowerOfProlog" rel="nofollow">https://www.youtube.com/@ThePowerOfProlog</a><p><a href="https://www.metalevel.at/prolog" rel="nofollow">https://www.metalevel.at/prolog</a><p>[2] <a href="https://www.youtube.com/watch?v=nmBkU-l1zyc" rel="nofollow">https://www.youtube.com/watch?v=nmBkU-l1zyc</a><p><a href="https://www.metalevel.at/acomip/" rel="nofollow">https://www.metalevel.at/acomip/</a></p>

<p>No, and its ok to be dismissive of it. I'm just giving an experience report.<p>Actually my primary value is emacs integration with claude.<p>I have an mcp with one function ( as_user_eval ) which allows it to execute arbitrary s-expressions against the portal package for emacs.<p>I use this often with custom slash commands, i.e., `/read-emacs`, which instructs claude to use that mcp to pull the context from multiple pseudoregions in to the context window (along with filenames and line numbers). This saves me from having to copy paste all of that.<p>I understand what the others are saying but the using the portal to talk to a running emacs client I don't find to be particularly "discoverable" on the cli.<p>I can say things like, "show me in emacs the test that failed", or, "highlight the lines you are talking about", or, "interactively remap my keybindings to do X", or, "take me to the info page that covers this topic".<p>This, paired with chrome devtools and playwright, had been a real productivity booster for me, and is quite fun.<p>I use voice dictation for this so it feels like I'm in Star Trek :)<p>I'm sure in 10 minutes we will be onto the next version of MCP... skills, ACP, Tools, whatever.<p>But this extensibility/discoverability for me has been nice. I make no stronger claims than that about "what it is for" or "what is should be", as I am a simple hacker with simple needs.</p>
