>The robot doesn't just need a prediction about the next frame

But the residual stream of LLMs doesn't "just" encode the next token prediction, it is high-level enough to encode predictions for a few tokens out, as seen with things like Multi-token prediction.

But yes I can see that in terms of input, you probably don't want to take in video frames directly and training via teacher-forcing is probably inefficient here. So some world-model-tailored embedding like JEPA is probably better. I guess my confusion is that Yann seems to frame it as JEPA vs LLM, but to me JEPA just seems like an encoder to generate embeddings that can be fed into an LLM. They seem complementary rather than a substitute.

>At my work currently IT have the first say and final say on all software, regardless of what it does or who is using it.

Yeah but software isnt software.

Like I have a customer with users that just randomly started using VPN software to manage their client sites. VPN software that exposes the user machine directly to uncontrolled networks. This causes risks in both directions, because their clients run things like datacenters and power stations. Increases security risks for their business, and increases security risks for their customers, not to mention liability.

IT should be neutral. but IT done right, is guided by best practice. IT is ultimately responsible and accountable for security and function. You cant be responsible and accountable without control, or you exist just to be beaten up when shit goes sideways.

>the ones that actually make the company money...

Making the company money in an uncontrolled fashion is just extra distance to fall. If you ship a fantastic product with a massive supply chain induced vuln that destroys your clients there was no point in making that money in the first place.

LLMs start to bog down with it at a certain point too. For a couple of my side projects, I decided to let things rip and now worry about code structure at all. After a certain point some of the changes I wanted to make just started either failing work racking up large bills. It would try to make a change, run tests, realize it broke something somewhere else, try to fix that, cause another issue. Undo the original thing, fix the new issue, maybe try to refactor, partially, fail, revert that, decide to make the tests pass by removing the tests! and then keep some broken version of fix. With a few similar cycles of that on repeat as well.

Deliberately telling it how to rethink the structure, refactor first, then seperate out components fixed things.

IF LLMs stayed at the current level, I would expect llm-aided-coders to learn how to analyze and address situations like this. However, I do expect models to be better able to A) avoid these kinds of situations with better design up front or reflection when making changes and B) identify more systematic patterns and reason about the right way to structure things. Basically ambiently detecting "code smells."

You can already see improvements both from newer models and from prompt engineering coming from the agentic tools.

Your thoughtful question is definitely along the lines where the research could change health outcomes. Apple Health currently tracks trends over time and can alert if any disconcerting trends are identified. If Apple were able to capture a breathing signature at rest, say once a month, trends could be identified (via training data, as you mention) and data optionally provided to healthcare providers.

Some people who are alone (including my father) have no idea that they have sleep apnea or 'odd' breathing - for apnea, they're obviously asleep, and for other breathing factors, it's usually a slow and unnoticeable progression.

I agree with you, the problem currently is that the balance of power has shifted so far in favor of the 0.1%. And those people will not want to give up the power that they already have.

I fear for a future where the technocrats win out and we end up in an "Altered Carbon" scenario. We are on the precipice of AI and robotics equalizing the playing field for everyone, but only if the power is held by the people and not the few at the top with the most resources.

Not sure how to steer the ship in that direction, but I do have a few ideas...

There is a bug in the calculation of the known prefix.

Suppose the target word is before tin, but after timorous. Midword only displays "ti" for the known prefix. But it should display "tim" - there is no string that could start with "tin..." but sort before the string "tin".

(Another bug is that if you take a hint that would reveal the entire word, the site doesn't display what the word was.)

I use MS Authenticator for work too. It doesn't do standard TOTP, at least not for Entra. The QR codes don't contain the secret. IDK that anyone has been able to exfiltrate a secret and generate codes with a third party app.

I personally use an Android emulator on my laptop, which achieves the same goal. It saves and restores state automatically for quick startup.

This was a big reason for dart canceling its previous macros attempt (as I understand it). Fast compilation is integral for Flutter development - which accounts for a late percentage of dart usage - so after IIRC more than two years of developing it they still ended up not going through with that iteration of macros because it would make hot reload too slow. That degree of level-headedness and consideration is worthy of respect IMO.

I just tried in the app on Android and it would not allow me to take more photos unless I pay.

When you say "you have access to everything as part of the free tier", does that apply to Android as well?

Because what you are saying is not true on Android. After 3 photos I cannot take another, the message says "You used all of your photo logs! As a free tier member you get 3 free Photo logs per day."

You are claiming that this is different on iOS?

This is exactly it. QC right now is a series of very cool science experiments that are being marketed to [Government Officials, CEOs, Investors, the General Public] as product development, which it is not. We're at the stage of scientists in the 1910s creating the first vacuum tubes and noting the ability to amplify and control small currents with larger ones but these companies are pretending it's instead the early 1980s with the PC and 8088 and Moore's Law getting ready to take off like a rocket.

These factors are now getting baked into the tools. Primarily via prompt engineering, and what might be called "agentic design," which is how much complexity you put into a single pass vs some hierarchical layering of agents and tools with distinct jobs.

I've been deobfuscating claude code to watch their prompts evolve as I use it and you an see the difference around how and when it chooses to re-analyze a codebase or how it will explicitly breakup work into steps. A lot of the implicit knowledge of software engineering is being added, _outside_ of the LLM training.

> fighting terror using software is valid

Only if you want to live in an Israeli-type society where a certain group is inherently suspicious and have no rights. Americans should be repulsed by that.

That's why I don't buy the judeo-christian propaganda about how our values are the same. The western values are justice and due process and "all men are created equal", zionist values are "we are god's chosen", no holds barred "war on terror" with no due process, invoking religous amalek to commit genocide. These are the values of an ancient desert tribe not western civilization. Zionist values have been forced onto the west over the last 30 years as Israel tries to rope us into more middle eastern wars, but they don't derive from western enlightenment philosophy.

> I believe that in practice, forced password changes at least ensure that unknown compromised passwords will become outdated at some point in time, and I think that this is positive.

password

password1

password2

password!

Password1!

People get predictable on how they modify their passwords when that policy is instituted. Mostly because it's a royal pain in the ass to have to generate a new password AND remember it.

That was one of the reasons that browsers (etc) began offering users randomly generated passwords that either the browser, or a 3rd party tool/service recalling the password on demand.

However that then means the password to the browser/service becomes the unchanging password...

> Ultimately, I believe the best thing to do is to move to FIDO2-authentication here.

Passkeys are an attempt to circumvent this by having (effectively) a key that's attached to some physical device that the user must have access to to prove that they are the authorised user... but... people are circumventing those by storing them in cloud services... which means that the password to the cloud service is... yet again.. the weak point.

> But I do wonder what are other peoples takes on this topic?

For my money, the problem that's being attempted to be solved is unsolvable.

In the physical world we determine identity by citing documents that verify the identity as far as a trusted institution like a government or bank is concerned, and those documents are predicated on documents that may or may not exist (birth certificates) and the assurance that those documents are for the person presenting them, from other people that have been through the same procedure.

The digital world is even more difficult to prove identity with, because everyone looks exactly the same, ones and zeros, the order might be different from one person to another, but they're mutable.

Hey all

I’ve seen a lot of confusion around agent memory and how to structure it properly — so I decided to make a fun little video series to break it down.

In the first video, I walk through the four core components of agent memory and how they work together:

Working Memory – for staying focused and maintaining context Semantic Memory – for storing knowledge and concepts Episodic Memory – for learning from past experiences Procedural Memory – for automating skills and workflows I'll be doing deep-dive videos on each of these components next, covering what they do and how to use them in practice. More soon!

I built most of this using AI tools — ElevenLabs for voice, GPT for visuals. Would love to hear what you think.

Maybe what is needed is selective gating - some PRs are the type you REALLY have to make sure are reviewed; others can go through a barrage of AI reviews (security, code-quality etc) and the author can merge.

Either human or AI (or both?) needs to be tagging PRs. Perhaps a traffic light system is appropriate? Red - needs close human review; green - AI review only; yellow - unclear / somewhere in the middle.

Using PRs to merge features gives auditability and traceability to which human merged which thing.

As always, it is situational. AI is exposing new shades of grey.

Customers need to ask for these changes, which is why this is hard to solve. At least in my field, many of the measures we end up having to fall in line with are the result of our customers deciding that those who bid on their contracts must have these certain credentials. If those same customers had more competent decision-makers determining technical qualifications then this would be less of an issue. Unfortunately, that also means that we will be stuck with these audits in their current form until the vast majority of our customers first decide they’re not needed.

I work in neurotech with auditory stimulation, so you'd think I'd be a big fan of this area of research, and I think the authors have done a decent job of suggesting the limitations, but the title itself gets picked up and people read a lot into what they think this is saying. Or maybe I'm just a bit jaded.

They provide a 2.4 Hz stimulus and then measure frequency-matched activity across brain networks. They suggest some novel methods of measuring how the signal traverses the brain, but they don't suggest why it does, which is good. They do say this is unlikely to be entrainment, I'll get into that more in a bit.

We shouldn't be surprised that auditory stimulation produces frequency-matched activity across distributed brain regions. The auditory system naturally routes information across multiple interconnected networks. The auditory system picks it up, but the auditory system is also not siloed into a single area of the brain. No brain systems are, we have replication, and this is just showing the the nervous system is passing the signal throughout the brain. In no way does it suggest that this is related to thought, consciousness, focus, or that these frequency-matched responses reflect any functional change in brain state.

When people talk about entrainment, that is a real thing. But the word itself describes when systems synchronize, not that they will.

I guess I'm cautious about papers like these because of our work in neurostimulation and sleep where we use phase-targeted auditory stimulation to enhance slow-wave activity. Basically increasing sleep's restorative function.

In our work it isn't this sort of "gentle tones to help you sleep", or "activating networks to alter brain activity", which is an area I see a lot of snake-oil and nonsense.

The way closed-loop phase-targeted slow-wave enhancement works is by "interrupting" the brain during the synchronous firing of neurons, which (it is believed) triggers a protective mechanism in the brain and as a response, the brain increases the synchronous firing of neurons. We're talking about very short (50ms) interruptions.

I get my back up a bit when I hear about this idea that reading electrical activity of the brain and making broad assumptions about what they "mean". I've been invited to speak on a panel July 2nd with Australia's Commissioner of Human Rights to discuss ethical safety around EEG data, and while I do believe we need to protect bio-data, I don't believe in the "electrical activity means we can read or alter your thoughts" camp.

If you want to know more about our work, you can check out https://affectablesleep.com, and if you're in Sydney, and want to come to the talk, I can't find a link atm, but it's at the Sydney Knowledge Hub on July 2nd., part of the Sydney Neurotech Meetup

It seems like the problem here isn't the use of checklists, it's that the checklists in question contain questionable stuff like "enforce frequent reauth". Systematically checking for the presence of good things and the absence of bad things seems like a good idea both from a security and consistency perspective. Of course the trick is making sure your "good" and "bad" lists are well thought out and appropriately applied.

This article is about NASA, and the existence of a large and successful pharmaceutical company industry proves that when there is a public good to be achieved, there is private funding for the research.

The OP asked for an answer, and the fallacy I’m trying to point out is this assumption that “all” research is generally worthwhile. And I don’t mean just that there are exceptions, but swaths of topics and institutions and researchers and methods that aren’t really adding anything of value. Some areas, like aerospace, have been the focus of intense research for a long long time. This is to the point where SpaceX has been able to walk in and build a space program from scratch. I don’t mean to minimize their hard work, but it just shows that we’re not in the 1930s anymore. It makes sense that you should occasionally adjust your priorities from time to time based on your needs.

Dear god, PLEASE hire an actual Enterprise IT professional early in your startup expansion phase. A single competent EIT person (or dinosaur like me) could have - if this story is true - possibly saved the whole startup by understanding what’s immediately needed versus what’s nice-to-have, what should be self-hosted versus what should be XaaS, stitching everything together to reduce silos, and ensuring every cent is not just accounted for but wisely invested in future success.

Even if the rest of your startup isn’t “worrying about the money”, your IT and Finance people should always be worried about the money.

Haha, Marijn Heule who is pushing a lot of limits of SAT solving would love this. If you manage to get him excited, he might spend a few years on this problem :) He's kinda famous for solving the Boolean Pythagorean Triples problem using SAT [1]. He loves puzzles. He also got Knuth excited about a bunch of fun puzzles.

BTW, these puzzles also tend to have a lot of symmetries, which SAT solvers are pretty bad at handling. You can break them, though, using a variety of techniques, e.g. static symmetry breaking [2], or symmetric learning.

There are a lot of tools to do this easily today, for free! Take a look at Postshot, or Brush. You can literally take a video with your mobile phone, toss it in Postshot, and a few minutes later you have a photorealistic 3DGS model you can use in Spark!

All of this is forced, yes. There's probably a trillion dollars riding on this all not imploding, so we're getting it shoved everywhere, all the time, incessantly.

My own experience with "Agents" (and no, I am not a luddite) has been nothing short of comical in how terrible it's been. We try it every single day at our company. We've tried all the advice. All the common wisdom. They have never, not once, produced anything of any value. All the public showcases of these brilliant "agents" have also been nothing short of spectacular failures [1]. Yet despite all this, I keep seeing these type of posts, and pretty much always it's from someone with a vested interest of some kind when you dig deep down enough. All the managerial types pushing it, you look deep enough it's always because the board or investors or whatever other parasite has a vested interest.

I know one thing is for certain, what AI will give us is more and more fucking advertisements shoved into every facet of our lives, except now it sorta talks like a human!

I actually cancelled my order of the BSB2 because I decided that I like having a camera to temporarily see around me when I'm moving out of the safe area. They responded to that by basically saying 'yeah a camera would add some amount of extra weight and we're trying to cut as much as we can'.

Unless you have perfect reproducible builds, this is a security nightmare. Source code can be reviewed (and there are even projects to share databases of already reviewed Rust crates; IIRC, both Mozilla and Google have public repositories with their lists), but it's much harder to review a binary, unless you can reproducibly recreate it from the corresponding source code.

Forced password rotation and expiry seems the bigger problem; given that it causes people to get locked out so often, (e.g. if pw expires when on holiday), — often then requiring travelling to IT, or at least a few hours trying to get IT on the phone to reset, or chasing up colleagues who aren't locked out to get in touch with IT.

Many (most?) companies still do it, despite it now not being recommended by NIST:

> Verifiers SHOULD NOT require memorized secrets to be changed arbitrarily (e.g., periodically)

https://pages.nist.gov/800-63-3/sp800-63b.html

Or by Microsoft

> Password expiration requirements do more harm than good...

https://learn.microsoft.com/en-us/microsoft-365/admin/misc/p...

But these don't seem to be authoritative enough for IT / security, (and there are still guidelines out there that do recommend the practice IIRC).
