What do you want out of helical cuts that G03s don’t give you?

Eventually, something actuates a servo, and servos don’t understand iteration. Do you agree eventually something with g-codes level of detail must exist (even if it’s just unspecified internal commands)? If so, do you agree you’re just advo

What would a good G-Code variant look like? For all its flaws, it's pretty good at encoding the exact thing you want the CNC machine to do and while there certainly are different post-processors for different machines and in most cases

You can, but at least a few years ago most cheap readers would horribly mess that up (usually not render it at all). And those that didn’t were typically nice enough that they could just render the PDF correctly ;)

I don’t know if you picked those judiciously or if I did but those are two blog posts I did actually write :)

I looked at them before and they couldn’t do the illustration generation I needed, but maybe with some preprocessing on my side and some on theirs :)

I definitely want to work on it more but I think completion goals are going to be at a chapter level maybe -- there'll always be stuff to add :)

Yes! It hasn't gotten better. I wrote Crypto 101 for a reason -- there are a number of problems I have with both the approach, and even if the approach were good, it's horribly outdated now. Serious Cryptography is also good and m

Yep, I took exactly the same path. Still use org-reveal sometimes but pandoc is really great and anything-to-anything :)

Sure, I should get around to that :-) Really I'd like to make a docker image or similarly repeatable environment that can do builds -- right now it's way too tied to my own environment. Also: I'm not sure org-mode -> TeX w

Gotcha. Serious Cryptography is good. Applied Cryptography is... not. Except insofar Latacora making stickers that make fun of it and people printing t-shirts to benefit charities is good of course :-)

You can get the org mode plaintext source here: https://github.com/crypto101/book . It doesn't read as well as the PDF because there's a ton of illustrations and _something_ has to render them.

> More generally, I think the distinction between a "block-based stream cipher" and a block cipher (or permutation) mode is the degree to which you abstract away the block cipher. Just to make sure I understand you correctly, f

I'm not sure what "complete" would entail :) For example: would a description of Noise be in scope? I think so but I'm not sure. People come up with new cool stuff that's useful to median developers on the regular (

The purpose of the book is explicitly to mint developers who can responsibly build cryptographic features, not mint cryptographers -- so a detailed look at e.g. differential cryptanalysis is pretty clearly out of scope. AES is pretty much a

Do you mean "Serious Cryptography"? Applied Cryptography isn't a No Starch Press book.

... because the only way to introduce ciphers is, what, chronologically? Why? And why does that make it superficial?

by lvh 8y ago
What would you have preferred to see that wouldn't make it "superficial"?
650.
by lvh 8y ago
Because the book tries to produce a narrative where new features are introduced out of obvious necessity: in this case, encrypting more than a block. And you can do that with modes of operations or "native" stream ciphers. Essenti

I'm glad you feel that way, because I'm honestly embarrassed by how shoddy my old writing is. (I'm the author.)

Hi! I'm the author. Happy to answer questions.

(I'm the author.) Because it's not a priority for me and I never got the org -> epub generation flow working correctly. In particular, the book has a lot of illustrations, and getting illustrations right across a ton of ebook r

Huh? The current version of the GPL has a similar patent clause, and its no different in the treatment of object code AFAICT?

I prefer to keep locally installed Pythons for regular use everywhere, though I guess some distros get the same effect by patching pip to make `--user` the default (and hence pip install xyzzy goes to my home directory instead of messing wi

The article doesn't mention pyenv, which I've used to great effect. It does pretty much everything I want, including having multiple environments active at once (so that tools that want to do their own virtualenv management, like

That’s only true if Chromium does everything correctly, and even then it ignores the chilling effect where nobody cares unless Chrome does it. Right now I have perfectly valid SVG and HTML5 that straight up does not work correctly in Chrome
