...List. If your library relies heavily on accessing elements in these lists, then eventually you'll find that you've made a poor design decision; you'll realize that you should have used an ArrayList (which gives O(1) access time) instead of a LinkedList (which gives O(n) access time). Assuming you ha...

...it from a module. Define an actual instance of an object in a module, and then any client code can import it and actually get a working, fully constructed / populated object. This is in contrast to Java, where you don't import actual instances of objects. This means you are always having to insta...

...ppens if there's no serial device to find. I did as above and it worked. I then unplugged my (FTDI) serial device from the USB and afterwards it produced the error that you described. – Warpspace Jan 29 '19 at 8:30 ...

... if CC :=${GCC} ${FLAGS} during the first encounter is evaluated to gcc -W then each time ${CC} occurs it will be replaced with gcc -W. Recursive assignment = A Recursive assignment expression is evaluated everytime the variable is encountered in the code. For example, a statement like CC = ${GC...

...sted typedefs became redundant, and I wish they had been removed there and then. For the same reason (impossibility to add internal typedefs), T[N] doesn't model the STL Sequence concept, and you need kludges such as std::array<T,N>. Boost.Range shows how a modern Sequence concept can be defin...

...rray with an O(1) slice. If you're working with small arrays inside loops then you may get some performance gains from avoiding that negation, and if you're working with huge arrays then you can save on memory usage because the negation creates a copy of the entire array. Note that these methods...

...son between some elements (e.g. you first claim A < B and B < C, but then C < A). It also ends up as a more complex (in terms of execution time) shuffle than you really need. I prefer the shuffle algorithm which effectively partitions the collection into "shuffled" (at the start of the coll...
