I'm curious about the amount of data stored unencrypted in your local hister vault.

Would that in itself become a security vulnerability?

And if so, would you consider specific sites or categories of sites to tell the tool not to index?


Ohi, author here. The index you build can indeed contain sensitive data, but you have the ability to specify URL patterns to skip the indexing of the matching pages.

Personally, I'd love this is if it were opt-in. That way, I could gradually reduce my repeat search dependence based on me recognizing my actual habits, rather than giving a browser extension carte blanche access to my entire search history. Maybe that's already possible, but I didn't see any documentation about the config file.

sure all data collected is of value to someone, browsing history is definitely. however this is decentralized, and needs targeted attacks, so depending on your threat model, this might be bad, but for most of the users it's probably better than giving a search engine your search queries for pages you visited earlier.

It's probably not hard to deepfake him eating a fruit.

The win of what he's doing is probably a lot more social than technical. It's funny and calls attention to the problem, which brings a lot more people to report the fraudulent channels.

It likely gives him some virality (I for example would not have seen the video if it wasn't for this)

And also, it gives his loyal followers more reason to check his website directly.


https://en.wikipedia.org/wiki/List_of_laser_types

Wavelengths of commercially available lasers. Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material


That's a better break down thank you.

Funny, I posted the same link yesterday.

It is, I've also seen the same link before many years ago. It has been updated a few but relatively the same elements and experiments used still.

Why is there no xray or gamma ray lasers?

Try reflecting X-rays or gamma rays and you will understand why.

Reflecting X-rays is exactly what's needed for EUV litography, Hiroo Kinoshita had to fight quite a bit to have his research taken seriously back in the days but it's the foundation to how EUV lithography works.

Uhh.. can you be more specific? I think it's possible to reflect xrays https://en.wikipedia.org/wiki/X-ray_reflectivity https://x-ray-optics.de/index.php/en/physics/reflection


I've found that it's often useful to spend the time thinking about the way I would architect the code (down to a fair level of minutia) before letting the agent have a go.

That way my 'thinker' is satiated and also challenged - Did the solution that my thinker came up with solve the problem better than the plan that the agent wrote?

Then either I acknowledge that the agent's solution was better, giving my thinker something to chew on for the next time; or my solution is better which gives the thinker a dopamine hit and gives me better code.



Veritasium (https://www.youtube.com/veritasium) has well researched content, but they are broad in terms of their topic selection.

Real Engineering (https://www.youtube.com/@RealEngineering/videos) is focused on engineering, but more on specific vehicles or products than individual concepts.


uv is a good example of this.


I absolutely love that Grady includes full transcripts of his videos.

It's much faster to read the article than watch the video, even though that hurts him by 1 view.

I just watched parts of the video after reading because I wanted to see his explanations.

One of the few really good creators out there.


Reading the transcript doesn’t even give you 10% of the information actually conveyed in the video which is why it’s so much faster.


I guess his area is really close to my field (Mechanical Engineering + Robotics) so what I learn from his videos is less the concepts themselves and more the interesting examples of them in the real world.

For example that hydroplaning is a real consequence on runways; or that higher takeoff weight has an order of magnitude greater effect on runway wear than the shear force of braking during landing.

I also learn from Grady's phenomenal skill at communicating technical concepts from our field in layman accessible terms! Most times I prefer to watch his videos and appreciate what he does, but there are days that I'm in the mood to read rather than watch. I'm glad that he gives us that option.


If you already understand the concepts you're not gaining much by watching the video.

If you don't then I'm sure it's better than nothing but idk if stock footage is where you should be developing your mental model of how a tire hydroplanes or how a paved transfers load into what's below it.


Some of it is stock but Grady has a lot of custom animations and miniature scale replicas in his videos all the time.


Writing off Practical Engineering's videos as "stock footage" is utterly hilarious to me.


C'mon. I know everyone on HN just can't help but glaze anyone who deals with "real world things" rather than 1s and 0s but this is absolutely not one of his more original content videos. You can't simulate landing aircraft using a clear plastic box (one of his better props) like you can soil conditions so you get what you get.


If you watched the video you would know he didn’t. Animations only in this one.


Important to note that it does not include a fine.

So the penalty for breaking the law is being forced to follow the law for 5-20 years? (Or am I simplifying it too much and missing something?)


> So the penalty for breaking the law is being forced to follow the law for 5-20 years?

That was how I read it as well…

Either I’m missing something obvious or this doesn’t seem like a punishment at all. I don’t get it.
