In Texas we lose people every year because they think they can make it across what looks like a small, shallow creek and are swept away by water that is really much deeper. You might think, “Well, those are stupid Texans,” but we even have

And it’s been confirmed by red teams sneaking weapons through checkpoints that it’s not even doing the basic job. Lots of hassle and expense for little to no gain in security.

In a sense, this is just an exercise in (possibly lossy) compression. 64-bit unsigned into are not lossy. 64-bit floating point is lossy but has larger range; it’s only able to encode a small fraction of the numbers in its range (in the lim

I’m not sure that problem 3 needs any solution at all, particularly a read-write lock. If a thread is updating the old set of bits when it’s time for a switch, just let it complete that write to the older set in parallel with the swap. Sinc

Did you use the same computer at both 60 and 144? I have no doubt that 144 feels smoother for scrolling and things like that. It definitely should. But if you upgraded your system at the same time you upgraded your display, much of the resp

Yep, agreed, though it’s not just keyboard to screen. It’s also mouse click to screen. Really, any event to screen.

Input lag is not the same as refresh rate. 60 Hz is 16.7 ms per frame. If it takes a long time for input to appear on screen it’s because of the layers and layers of bloat we have in our UI systems.

Mouse being jumpy shouldn’t be related to refresh rate. The mouse driver and windowing system should keep track of the mouse position regardless of the video frame rate. Yes, the mouse may jump more per frame with a lower frame rate, but th

Love your post. So, don’t take this as disagreement. I’m always a little bewildered by frame rate discussions. Yes, I understand that more is better, but for non-gaming apps (e.g. “productivity” apps), do we really need much more than 60 Hz

Those are exotic parts that would have to be manufactured specially. You don’t buy them off the shelf. They are costly to procure and difficult to work with. One doesn’t just load up the 3d printer and push Go. To be clear, I’m sure a homem

Of course. Lots of metal goes through the detectors. The point is that the detectors “see” it and that’s then your chance to catch it. Whether you actually do or not is another question. But 3d printing a gun doesn’t give you a “plastic gun

It’s not even doing that. It’s just an algorithm for predicting the next word. It doesn’t have emotions or actually think. So, I had to chuckle when it said it was arrogant. Basically, it’s training data contains a bunch of postmortem write

You still need metal parts, notably a gun barrel capable of holding extreme pressures until the bullet gets up to speed. That isn’t plastic. The grip and frame might be plastic, but not the barrel.

Sure, but The Zen of Reticulum repeatedly says that all that centralized infrastructure is bad, bad, bad. So, it seems a bit like cheating if you still need all that to scale.

To be clear, I’m not harshing on Meshtastic’s node counts. In some sense these systems are like packet ham radio. They appeal to a specific user base. I just question how their protocols are going to scale, and even 150 nodes is extremely s

Just so I understand, what sort of bootstrap process are you looking for? Even a pre-built binary is going to require a download? If you build from source (e.g., C), you’re going to need to download the source code and a compiler. I’m not m

Exactly. And are you going to break it one day just because and force every node to run the new version of firmware to stay active. I like implementers who show some transparency and some self-reflection about the limits of the protocol. An

Exactly. Okay, that’s a great claim. How? Also, “planetary scale” is meaningless. With the right node count (low), topology, and radios, just about any mesh network can achieve “planetary scale.” But that doesn’t mean it’ll support 10 thous

Okay, maybe Reticulum isn’t strictly LoRa-based, but others are (e.g. Meshtastic), and while Reticulum works over lots of physical layers, the README specifically states “An open-source LoRa-based interface called RNode has been designed sp
