Methods for Interpreting and Understanding Deep Neural Networks

For general compute they will lose to a laptop, but that isn't supposed to be their purpose. I think the best use cases require extra hardware that would make a laptop too bulky or awkward. For example a deck with a VNA, SDR, scope, and arbitrary waveform generator for field work with radio equipment. The traditional computer capabilities are sort of extra. Any sort of diagnostic "cart" with a dedicated computer and a bunch of test equipment could be a candidate for miniaturization.

That's what I'm asking... Why not? I'm alluding to what seems to be a culturally self-imposed refusal to seek legal remedies among makers and hackers. We have Jeff Geerling (who I generally like and agree with) disappointingly referring to the GPL as a "social contract," as though it can have no legal force behind it.

The biggest companies in the world use licenses to weild power over people, but heaven forbid people use the same body of law to their benefit.

There is something about the asymmetry of effort that is particularly galling. If a person couldn't be bothered to write something, then I can't be bothered to read it.

If someone contributes a software component, they are responsible for it whether they developed it properly or slop coded. The difference is that I will refuse to look at the slop, much less debug it or help with troubleshooting.

People who blindly copy paste from agents are completely replaceable, and should be at the top of the list when layoff season hits. They drag the whole org down.

Recent updates to Microsoft account sign-in now support passkeys with device biometric authentication, making phishing virtually impossible.

So according to Microsoft biometric authentication will make people immune to being tricked. Pretty ironic stance.

I have dozens of volunteer red maple trees about shoulder to head height in my yard. I have been trying to find information about training them at this size. Do bonsai methods for Japanese maples work? Can two red maples be joined together to make an arch? I need to learn more about plants

I think I've tried every spreadsheet program still being maintained at this point. Try gnumeric, it's a clear cut above everything else.

Mandatory Excel rant: Excel can't be trusted with data destined for publication. It's bloated, buggy as hell, user hostile, and has set genetics research back with its utterly braindead autocorrect. The default plot options are the exact polar opposite of how data are presented in science, and almost impossible to make serviceable. Everything Excel touches ends up looking like a hastily thrown together 6th grade science project. Libreoffice is also riddled with serious bugs and also loses data, but hey it's free and not a decades old flagship product from a multi billion dollar tech company.

By leveraging Genie’s immense world knowledge, it can simulate exceedingly rare events—from a tornado to a casual encounter with an elephant—that are almost impossible to capture at scale in reality. The model’s architecture offers high controllability, allowing our engineers to modify simulations with simple language prompts, driving inputs, and scene layouts. Notably, the Waymo World Model generates high-fidelity, multi-sensor outputs that include both camera and lidar data.

How do you know the generated outputs are correct? Especially for unusual circumstances?

Say the scenario is a patch of road is densely covered with 5 mm ball bearings. I'm sure the model will happily spit out numbers, but are they reasonable? How do we know they are reasonable? Even if the prediction is ok, how do we fundamentally know that the prediction for 4 mm ball bearings won't be completely wrong?

There seems to be a lot of critical information missing.

These people aren't temporarily insane, they have always been this way. The same hatred and stupidity have been prevalent in US dinnertable discussions for decades, but much less in the actual halls of power because we used to have more collective sense to not grant people like that authority over others in general. If the rest of American society regains its agency, the toxic %25 will just go back to corroding the country as they were before. They are secure in knowing they will not be treated in the way they would treat others if given the opportunity.

I found it odd they specifically said not to make a git repo for the page, GitHub is one of the easiest ways I know to publish a website. It just can't be commercial etc

A key property of QCD is that unlike electrodynamics, the forces between interacting objects increase with distance (quark confinement). This is what breaks the usual style of expansions used to simplify problems. It's hard to overstate how important this is.

One of the implications is that there are many interactions where most possible Feynman diagrams contribute non-negligibly. The advances in theory arguably have much more to do with improvements in techniques and the applied math used, such as in lattice QCD and Dean Lee's group for instance.

If it's the computer of an older family member or something, just put Firefox and ubo on their system for them and be done with it. They will use whatever software is preloaded, and being shown how to use it is a much lower barrier to entry than the cognitive load of finding, vetting, installing, and configuring new software.

I used to try to patiently explain why people should do xyz. Now I explain to people why I'm going to change xyz on their device, and if they don't slam the breaks I just do what needs to be done right then. If someone doesn't know what an adblocker is they are getting one so they can see for themselves and reflect on what companies have been putting them through for years to make some incremental amount of money.

Part of the problem is that software engineers aren't real engineers. Engineering disciplines formally recognize their responsibilities to the public, and are expected to refuse to build dangerous or harmful systems.

The mechanical engineers who design cars and the civil engineers who design the roads and bridges they traverse are held to these standards, and hold themselves to these standards. The software engineers who write code that actually controls vehicles in practice have no such culture. Relevant professional organizations like the ACM should be leading the charge, but they aren't because their membership doesn't care.

One solution is to license software engineers. What do people working in the industry think about that?

Interactions between species are scarcely understood in general, if they are known at all. It's only very recently that the existence of mycelial networks was discovered. It's only very recently that the importance of micro biome and it's role in health is starting to be recognized. It's only in hindsight that impact of the near extinction of vultures in India on human health was understood.

History has shown industrialized humans to be dangerously ignorant of environmental systems, and almost every action we take with regard to these systems is destructive. Every extinction is irreversible. Things are so wildly out of equilibrium now that it's no longer possible to return to the equilibria from our past.

Ecological collapse isnt some mild inconvenience that makes milk more expensive. Once it has happened, ecological collapse cannot and will not be undone by the seriousness of "business." This type of thinking embodies exactly the kind of arrogant hubris that led us into this situation. The negative feedback loops that have kept earth habitable for us so far aren't laws of nature, and no-one knows how far they can be bent before breaking, or how they even work.

That is still cheaper than the index when it came out, and it sounds like a general improvement in all areas. Flagship vr for less than the cost of the latest smartphone seems pretty reasonable given how low adoption is.

Yep I have this and it's total garbage. The scheduling options feel designed to troll, serious MacBook wheel vibes. No way to temporarily disable the schedule if you're going out of town. Either turn your HVAC off entirely, or delete the entire schedule and manually reenter the whole thing when you get back (who doesn't love life-wasting menu diving after a long trip?).

Vaguely projecting forward the relationship between total cumulative funding and experimentally achieved q value, it's not unreasonable to think that this money could have brought us to commercially viable fusion power if spent judiciously over a longer period of time. It's pretty typical that we collectively spent the money on an orgy of waste instead.

This could be useful for undergrads getting their feet wet with LaTeX and the world of publishing. However, I'm very skeptical that the options are broad enough to conform to the exacting style guidelines typical of PhD theses. Usually people use a template from their school which already formats everything, autogenerates the table of contents, etc.

In fact it isn't clear what this system offers over a LaTeX document started from a template and hosted privately on GitHub. The CI pipeline can even be set up to compile the document for the people who want to be able to do everything in a web browser.

This isn't exactly what you want, but you could get the same kind of breaker interlock used for traditional generators and use that for the solar inverter. The downside is that you can't blend grid and battery power at the same time, but this may not actually be a problem in a practically sized setup where solar is the primary.

Selling Lemons 10 months ago

It doesn't matter whether it's possible for a highly motivated and educated person to distinguish the lemons. This will usually be true. The important thing is the experience of real consumers participating in the market as it actually exists. A better framing would be "of all products in category X sold last month on amazon, what fraction were lemons?"
