Hi there everyone. I am using a function which calculates the cartesian product of 2 lists. (defun cartesian-product (list1 list2) "Return a list of the Cartesian product of two lists."
Контекст: я более-менее свободно работаю в Common Lisp в slime в emacs, хотя последние годы это было крайне редко (на лиспе стал писать в своей оболочке «Яр»). В остальном мой любимый редактор - это VSCode.
I won’t cover every bit and field here, but the instance ID is worth mentioning. The instance ID is a 24-bit value that has a similar function as the Route Distinguisher (RD) in MPLS VPN . newtype First a = First {getFirst :: Maybe a } deriving (Eq, Ord, Read, Show) instance Monoid (First a) where mempty = First Nothing First (Just x) `mappend` _ = First (Just x) First Nothing `mappend` x = x ghci > getFirst $ First (Just 'a') `mappend` First (Just 'b') Just 'a' ghci > getFirst $ First Nothing `mappend` First (Just 'b') Just 'b' ghci > getFirst $ First (Just 'a) `mappend` First Nothing Just ' a' ghci > getFirst . mconcat .

2007-07-23 · Going into chapter two of Paradigms of Artificial Intelligence Programming, we get a deceptively simple program to experiment with. The code for this chapter is located in the file simple.lisp, but note that the file does not include the mappend function from section 1.7.

Google says: "Avoid nconc!" They recommend to use "mappend" instead, which you could naively define this way (naive because it's O (n^2)!): (defun mappend (fn list "ul") "Append the results of calling fn on each element of list. Like mapcan, but uses append instead of nconc." Hi there everyone.
Note that this version of mappend doesn’t work exactly the same as Common Lisp mappend, since it doesn’t allow a lambda. Getting back to the generate method. LISP+ALT and LISP-DHT in terms of mapping delay, mapping load, and packet buffering.
