kandi X-RAY | LittleD Summary

LittleD is a C library typically used in Database, SQL Database, Nodejs applications. LittleD has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

LittleD provides a SQL frontend to manage data under the relational model. This project targets devices of about the same capabilities as the Arduino Mega2560. In a nutshell, the system supports the creation of tables, data insertion, and SELECT-FROM-WHERE syntax. Error messages are supported but not mandatory. A simple configuration header file dictates which features are compiled in so the database’s codespace footprint can be controlled according to application needs. All code except that needed to interface with Arduinos is written in C. This project is part of ongoing research being conducted at the University of British Columbia’s Okanagan Campus under the direction of Dr. Ramon Lawrence. The work has been supported by Dr. Lawrence’s Distributed Data Lab, the Irving K. Barber School of Arts and Sciences, the Natural Sciences and Engineering Research Council of Canada, along with a list of people too numerous to name.

Swift: Animate object along animating path

Reducing memory waste when creating similar objects

QUESTION

Swift: Animate object along animating path

Asked 2020-Jun-18 at 21:56

I would like to animate little red dot rotating around circle that is expanding in a pulse manner (go from small to big, then start back from small). It seems that little dot keeps rotating around original shape and does not take into account that circle it's expanding... I have this in code:

Using CoreAnimation to animate the position of the red dot based upon the path assumes that the path isn't changing. You could, theoretically, define a spiral path that mirrors the expanding circle. Personally, I'd just use CADisplayLink, a special timer designed optimally for screen refreshes, and retire the CoreAnimation calls entirely. E.g.

Reducing memory waste when creating similar objects

Asked 2019-Jul-29 at 10:29

Suppose I have an object and I want to make many copies of it that will mostly be the same but with slight variations. What is the proper way to share the common properties between these objects without excessive copying?

For a concrete example

You can implement simple copy on write with the shared_ptr. I.e. store the smart pointer on big data shared across objects of class A. And when you need to modify this big data for the specific object of A - replace the smart pointer by modified deep copy (cloned object):

I.e. something like:

Install LittleD

LittleD can be managed using an Eclipse Makefile project. Either the packaged C/C++ Eclipse IDE or the installable CDT package must be used. First make sure that the repository is cloned. In Eclipse click File → Import…. Within the Select window, choose under C/C++ the Existing Code as Makefile Project option and click Next. Give your Eclipse Project a name and browse to the root of the project repository to use the code. Choose the correct compiler for your system and then click Finish. As noted above, there are a small number of make targets that can be used with the project’s Makefile. By right clicking the project in the Package Explorer and selecting Make Targets → Create…. Leaving all options at the their default, enter the name of the target to add (for instance, tests) and then click OK. You can then run the Make target by right clicking on the project in the Project Explorer and choosing Make Targets → Build…. Select the target from the list that appears and click Build. Finally, you can run individual files with main methods by opening them and click the green Run button at the top.
