Got the ChaCha RNG working with "absorb" and "squeeze" sponge-like functionality (it's cheating).

I think I need to completely rewrite my Trivium code and take a different approach. I just can't match the test vectors. Probably something to do with endianess.

An idea crashed into my head over the weekend and now I'm committed to seeing it through.

In addition to the Spritz cipher as a DRBG for PassGen3, what if I also added the ChaCha8 and Trivium stream ciphers, allowing the user to choose?

ChaCha8 is written and passes test vectors. Implementing it though means adding "absorb(data)" and "squeeze(count)" functions so I have a consistent API with Spritz.

Trivium is written but doesn't pass test vectors. I'm pulling my hair out as to why.

If you want to play around with it.

Hmm. Passing some, failing others. I *think* I know what the problem is, but I think I might forego it for the time being. I'm using it for randomness extraction to generate passwords, not to encrypt/decrypt data. So it should be fine.

Here's a fun way to comment your C# source code: start it with "https://"

Yup. A URL.

The C# compiler sees "https:" as an unused go-to label and "//" starts a comment for the rest of the line

Cassette tapes had a "side A" and "side B". So it's only logical that their successor would be the "CD".

For creative #JavaScript #DevOps out there:

What would you name a variable that holds 1 byte?

"byte" is a reserved word since ES3. Variables cannot start with a digit, so "8bits" isn't valid.

"data", "unit", or "num" could work, although less descriptive.

Capitalizing the first character as "Byte"? IMO, looks funny and might break convention.

A homonym? "bite".

For whatever reason, my brain is refusing to cooperate with me today.

Without disassembly, there are 43,252,003,274,489,856,000 unique permutations in a 3×3 Rubik's Cube. If sufficiently shuffled, that provides ~65 bits security.

Which means recording the colors of each of the 6 faces after two sufficient shuffles is enough to provide at least 128 bits security.

Lavender (the python) and Cooper (the husky) say "Hi!".

Lavender, my ball python, investigating my space last night.

She was finding some very interesting ways of climbing, so I had to catch it on video. Before this, she climbed up to my windowsill using a plug in a wall outlet. Here, she climbs into a bookcase using the top of a book that is sticking out.

My daughter was worried she'd fall, so kept by just in case. She also didn't Lavender to find her way behind the books and struggle getting her out.

Anyway, Lavender is a very curious snake.

The clock in the OS works by having the time updated based on the counter in the RTC.

Sun with #Solaris Zones made every object inside the kernel have a zone context and then very carefully abstracted and hardened any exchange across zone boundaries so that there isn't even a handle on global resources inside a zone.

So it followed that each zone could have its own clock object spawned and all existing software would seamlessly work inside a zone.
