-===== Programming ===== +===== Saving memory ===== 
-Devel API (latest): [[https://github.com/nodemcu/nodemcu-firmware/wiki/nodemcu_api_en-%28dev096%29]] +  * Avoid upvalues for context passed between event callbacks, as its very difficulat to get a handle on memory leaks created by these. Only use globals for this usecase. 
-Current API: [[https://github.com/nodemcu/nodemcu-firmware/wiki/nodemcu_api_en]]+  * Nil globals once they are no longer needed so that they can be properly GCed. 
 +  * Allocate resources and create closures on a just-in-time basis. 
 +  * The cost of require or dofile is relatively small, so break your program into overlays one per event and use a small stub function as a callback to load each. 
 +    * Use compiled .lc files and load using dofile().

-==== 1-wire ==== +It is not so easy. It need socket instance which will be used only for one DNS request, then socket will be destroyed. Response is performed by callback.
