In Common Lisp, there is `unless' and `when' but they don't allow `else' branch. (when CONDITION BODY) (unless CONDITION BODY) The value of the statement is BODY or NIL if it wasn't executed. I can't rememb

Changes are good! Sometime, when I want a change of perspective, I switch to different theme for a couple of days/weeks/months and then change again, and again, and again... I've noticed just changing the theme can help refoc

I wonder. IMHE this is the kind of edge that you know only because you've been bitten by a bug once. It's the same with floating point numbers. You may know that the representation is not absolute, that you can end up with NaN. B

It is not critical but I think it is interesting. For example, I've read Code Complete 2, and while browsing online I found that some of the claims in the book was not solid. - https://www.sicpers.info/2012/09&#x2F

Yes, rereading the thread, I think I'm going too far. My main and original point is the following: tests that only test memorization are good on their own ("Tests to help you retain information."). You need both memorization

On the first part of your post: We don't have the full test, so maybe the teacher had a preface saying "In the context of book XYZ...". That is what I do when I create flashcards for myself. I specify what knowledge I am test

Tests are one of the best technique to retain knowledge. It's called active learning, as opposed to passive learning. Space Time Repetition systems such as Anki or Mnemosyne or SuperMemo are based on 2 concepts: (1) knowledge fades ove

I used to fully agree with that feeling but not anymore. IMO they are two kinds of tests: 1. Tests to help you retain information. 2. Tests to evaluate your knowledge. Assuming this question belongs to the first kind (memorization) and the

Stupid idea for signing: use invisible characters to embed GPG signature (or signify(1) or whatever) inside any text you publish. This way, when the text is copy/pasted, your signature is still attached. You can even make browser and t

If your threat is google, it would be wise not to use google in the first place. As other mentioned, OSM is an alternative (not equivalent) of Google Maps.

Funny thing is, it depends on your threat model. Using google.com/XXX for all its services protect the user from being spied by external actors such as ISP because everything is hidden behind HTTPS. Whereas, with XXX.google.com, extern

Got it. Very much like the idea to check the code coverage to find out which tests you should run. First time I saw it. Is it common in other tools?

Slow is smooth, smooth is fast. Though I understand the intent, I think it has the risk to run into a run-hack-run-hack programming style. I'm currently reading Code Complete which advises against this practice. Instead, one should str
