This is such a fun paper which I couldn't find on LtU. It's about the very early history of programming (1950s and '60s), back when things we take for granted today didn't exist yet. On tak..

source: https://ro-che.info/articles/2016-04-02-descending-sort-haskell Descending sort in Haskell Published on April 2, 2016 When confronted with a problem of sorting a list in descending order in Haskell, it is tempting to reach for a “lazy” solution reverse . sort. An obvious issue with this is efficiency. While sorting in descending order should in theory be exactly as efficient as sorting i..

Please don't post more "This implementation..

(Windows에 내장) OpenSSL 의존이 생기면 복잡하다. libcurl static library를 사용할 때는 전처리기 정의에 CURL_STATICLIB 를 추가한다.Linker -> Input -> Additional Dependencies에는ws2_32.lib wldap32.lib crypt32.lib libcurl.lib를 추가한다.

https://www.geeksforgeeks.org/mark-and-sweep-garbage-collection-algorithm/ Mark-and-Sweep: Garbage Collection Algorithm Background All the objects which are created dynamically (using new in C++ and Java) are allocated memory in the heap. If we go on creating objects we might get Out Of Memory error, since it is not possible to allocate heap memory to objects. So we need to clear heap memory by ..
