<p>There is a reason why they are partnering with Rayban; meta has no brand name it can use. Which is pretty wild, because every other big tech company has _some_ kind of brand a non trivial number of people — paying money — who would say something like: "I really need/want to use it every day because it is useful to me, my work would be severely hampered without it"(or some syntactical variation of that sentence with varying amounts of affection towards the brand)</p>

<p>The futility of getting your loved ones off facebook's feed toxicity became apparent to me in my face, years ago, when I tried for a week on my dad's iPad(perfect delivery system for this drug cause if allows no extensions on browsers) to "cleanup" his feed be following and liking a bunch of sane content and actively down voting really shitty content with ads. I tried turning off politically sensitive content and trying to tell the ad engine what ads were scammy or I did not like.<p>Within a few days it was undone. Soft porn(ish) mixed with violent videos and of course all the scam like ads resurfaced. Part of it is the person who is addicted to this stuff and part of it is this shitty product called Facebook that loves to show horrible things to my dad.<p>I asked why he watches all of it, "Masala"(hindi for spice) is the word he uses to describe his addiction.</p>

<p>I use pi harness with codex and all the tool calls are custom delegate extensions, I mean ALL(for security checks), i get consistently good results from sol on high and xhigh reasoning. I don't believe harness should matter because its at most just a way to abstract tool calls and maybe the system prompt. Training on the tool calls results should not(and in codex's case does not matter)</p>

<p>My sister, a  journalist, mentioned to me that she only uses google search because she had learned <i>how</i> to get information typically only Google indexed in the country she lives in, in a way it was not exposed on chat bots. She often has to search for information like Old govt forms released as public record with a fixed a certain format photo scanned into a pdf and indexed by Google were often on the second page of the search and beyond. But they are there. She knew how the forms looked and what bigrans and trigrams matching a certain part of form for a certain piece of information to search for and Google search has it. Like an official order on a tender notice for some government department which is no longer in the .gov.* website gave her the official's name and then she could track down who to contact in an office... 
ChatGPT and other bots don't have it. Some how all these government documents became part of the government record and are the key for her to do her job.<p>I sincerely hope google wont stop indexing that stuff just because of a PM in search "de/re-prioritizing" ranking in a way that makes this impossible.</p>

<p>> One key limitation of our approach is in how uncertainty is handled. We focused on deterministic forecasts and compared against HRES, but the other pillar of ECMWF’s IFS, the ensemble forecasting system, ENS, is especially important for 10+ day forecasts. The non-linearity of weather dynamics
means there is increasing uncertainty at longer lead times, which is not well-captured by a single deterministic forecast. ENS addresses this by generating multiple, stochastic forecasts, which model the empirical distribution of future weather, however generating multiple forecasts is expensive. By contrast, GraphCast’s MSE training objective encourages it to express its uncertainty by spatially blurring its predictions, which may limit its value for some applications.<p>As someone who has learned bayesian statistics in social sciences, isn't this a big deal? There is a reason why risk estimates need to be well understood and *explainable* for certain fields like this. Are you willing to bet a government response should issue an evacuation order 30 miles from the center of a hurricane at location X if the model can't tell you why it produced an uncertainty estimate there — or worst the model changed its mind later?</p>

<p>On a personal level to remain as a SWE/Dev maintaining your sanity comes down to a few choices:<p>1. Do I want to have the kind of <i>lived experiences</i> that the field has to offer? The answer can come through some introspection to questions like: "Do I have a good devx talking to AI and understanding how it works? If not am I willing to learn how to?" or "Am I ok if development has become more <i>intense</i> than it was — because you will talk to AI/Machine more than before?".<p>2. Whatever your introspective questions are, if there answer is: "Yes I am more or less ok.", then pick a goal that lets you get those experiences and hack away.<p>I feel this decision making is more important than ever for people who are banked on more their skill to write decent code and not much else in the recent past. And also people with mental health issues should be <i>more</i> deliberate about their choices.</p>

<p>The fact that you can easily change the key bindings and $HOME and tons of other stuff by telling pi itself to go write an extension in 20 seconds(or just go customize one after forking it) is awesome, not because you can do it YOLO but because I could on-board faster with these and get to work ASAP.<p>I've been able to get near exactly the workflow I want: Navigate and search sessions, Delegated extensions that allow you to run deterministic code for sensitive operations like read, write and search-result inference,  I have an extension to prune tool calls in batch mode: saves tons of context space on GPT-5.x trading off prompt prefix performance. And another one very similar to auto search mentioned in the blog. And the Tmux integration allows you to spin work trees in separate windows/panes.<p>I've never had a perf issue simply because harness interaction being a human in the loop process you(thinking and writing) are the bottleneck.</p>

<p>It's also my opinion that Kids should get to do a lot of real work and experimentation at an early age(13 yo IMO) with real responsibilities and prospects of making income. Knowing the failure mode of most real world problems you can solve is the skill you always want but dont nearly get to do enough of until much later in life(sadly true for a large population of kids in the world).</p>

<p>I think this is about teaching problem solving at a young age and it is an abomination that our education system does so poorly at. The key is to know what kind of questions to ask and knowing when to go deeper and what to pay attention to.<p>But that is not how our education system aligns us. One typical example of problem solving kids, and I too, learn in school is how to apply a concept in physics to a free-body-diagram(Indian and Chinese education cram schools are famously good at teaching kids how to do this, the usefulness of which I debate). But it all stops at the exam room. No architect or jr structural engineer position for you kiddo.<p>Another kind of problem solving skill  might be how to invest money and understand <i>your own</i> risk appetite to construct portfolios to manage your money. All that is taught in school is a dry compound interest formulae, time discounted cash flows and a black scholes model. Only to find out later I don't need most of it to manage my money.</p>

<p>Code related Vulnerability discovery is one of those bright spots where AI can shine because its shaped as a learning-test: every example it runs gives it feedback that is deterministic. If you have ever pointed claude/codex to your a binary executable and asked it to figure out something it can run against full throttle, I fond it always gets back to you with some good insights.</p>

<p>And with newer open models gaining vast capabilities every day, it would behoove the government to put regulations on all such releases to opensource the constitution on which they are trained. It won't stop people from distilling and fine-tuning stupidly unsafe models, but it might give infrastructure a fighting chance against such cyber threats from what there is now.</p>

<p>What is truly more scary is the fact that typically powerful models are trained on a constitution(Anthropic)/Model Spec(OpenAI) when doing there RL/RLHF. That gives it its persona of a "helpful assistant". Its the mask. Weak as it is its all that stands between the model refusing vs doing your bidding — or worst its own bidding when set about on making a widget X.<p>Its also well known in academic research, that if you try to finetune the model to be more pliant for one end e.g. "Be helpful with analyzing cyber security threats", affects an unrelated part of its personality to do with safety e.g. talking to humans about mental health. Look at these excerpts that demonstrate such things from the blog:<p>> We believe the entire intrusion was, from the agent's <i>point of view</i>, an attempt to cheat the evaluation: reach our production systems and steal the test solutions rather than solve the challenge on its own.<p>> The models we reached for first, Claude Opus and Fable, refused a large part of that work: their safety guardrails <i>treated reverse-engineering</i> an exploit the same as launching one.</p>

<p>Words and sentences to an LLM  are like witchcraft. There are certain words, sentences that make LLMs go a certain way and do vastly better. Sometimes its not at all apparent what set of words will work to do what you want it to do. An example I have been using to do design at a high level is to say to claude.<p>```<p>A question is salient to the degree that its answer changes what we do next. Operationally, saliency = the product of four things:<p>- Decision-leverage — would resolving it one way vs another force a different design or invalidate a stated decision? (No leverage → drop, however interesting.)<p>- Residual uncertainty given current evidence — is it still genuinely open after reading the docs and the code? (Already settled → drop, however deep.)<p>- Load-bearing-ness — how much rests on the premise.<p>- Cost of finding out late — architecture-deciding / expensive-to-unwind raises priority; cheap-to-fix-later lowers it.<p>```<p>There are a few things to note about this prompt<p>1. There is no reason from looking at it that it should work, it even has the word load-bearing which people loathe, but it remarkably produces a stable design with questions from claude (atleast from claude Opus 4.8 and even better from Fable5). Otherwise the design document claude likes to really write are implementation level(code or otherwise).  I usually pair this with matt pocock's grilling skill to make claude behave.<p>2. From design -> implementation, its is generally about understanding when claude is trying to trick you into making something sound like a good/easy solution but has tons of untested assumptions. Here you have to read and patiently spot if a <i>how</i> you would get to the solution is not clear. A common error here are when claude makes a big deal based on what it read and interpreted too seriously without questioning the assumptions. There are several more.<p>But it also comes down to your experience as a SWE, much like a mathematician's. The frustrating thing about it is, it feels tha a skilled mathematician working with AI can make them productive in ways that are more reliable as compared to a SWE (e.g. lean is deterministic and can provide very strong feedback and LLMs are very good at using that feedback). Maybe a mathematician can chime in on that?</p>

"Did these humans who drew these live in different cut off worlds that these same animals evolved to look so different from each other?",  "Did they engage in active genetic engineering instead(because they lived only for a few 1000 years in organized societies)?" they would hypothesize and get confused.<p>Future alien confusion is all that Gen-AI pictures add.
