Here’s what I don’t get: why the many layers of obfuscation in the build phase? (I understand why in the binary linked into ssh.) Once the first stage, extracting a shell script fr…

You are not observing the "problem" of entropy running low. Because it doesn't. You are observing the misguided attempts of fixing this non-problem.

Yes, that's certainly a solution. Or using a certification authority for users (TrustedUserCAKeys in sshd_config), so that any user that has a signed certificate, and owns the corr…

> Also I’m curious about the 1-bit recording. Is that a thing? Yes. This homemade GPS receiver uses a simple comparator (1 bit) to sample the signal (after amplification to get the…

Here's a paper that shows reflections (Fig. 3, "S11") and insertion loss (Fig. 4, "S12") on coplanar waveguides, when using a sharp 90° bend, a 90° bend with a champfer and the cas…

The examples should only view the bit/address mapping, not be a complete example on how to access memory mapped peripherals.

It's still non-esoteric today: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.... ARM Cortex M4 supports adressing individual bits (often registers of hardware periphe…

The ban is specifically for the ability of the watches to covertly record or transmit audio, not about GPS logging.

There is no general relativity involved in calculating your position. Solving for your position is basic geometry, if you want to have better resolution, have good model for the ef…

A DAQ that reconstructs a perfect square wave (or a perfect stair-step function) is employing a "Zero Order Hold", and it would make a god-awful audio DAC. https://en.wikipedia.org…

Yes, b/w converting is not sufficient. Once printed, the yellow dots are hard to remove. http://imgur.com/a/kLovh And even when you mask them out so that they are no longer visible…

Yes, I know. And it's sad. I'm also not a "gui" person, and couldn't make a useful graphical interface if my life depended on this. But I'm especially confused as why this hasn't b…
