dtimer | Distributed timer , backed by Redis

i'm trying to create a multiple stopwatches in one page, i have found a code online that's working as same as i need, but there's a problem, the integer they're rendering is like 4.03 means 4 is like second and 03 is seconds, i want something like 4:03 or if you can give me any other code which works the same way this code is working, Thanks

i expect the output of 4.03 to be 4:03

I've installed cuda toolkit and I can run the samples without a problem. Now, I want to use cuda on my project and in my project I use cmake. So, in order to demonstrate my problem I created a simple example. I have 3 files, my main, which is "teste.cpp", a cuda file "hello_world.cu" and it's header. The only thing my main has is the call for a function at hello_world.cu, like this:

I'm working with a slam system, i've install dso, which the code can be seen here::

Everything works fine, I manage to compile and run without errors. But know I want to parallelize the code, using CUDA. I'm having lot's of trouble adapting it's CMakeLists.txt in order to be able to use CUDA. The original CMakeLists from dso is available here:

dso CMakeLists.txt

I'm trying to adapt it basing my changes on this implementation of another author on another SLAM system:

ORB SLAM 2 CMakeLists.txt using CUDA

Right now my CMakeLists, with my changes (not working), is like this:

Question: Without using any, What is the proper typing for my onMouseMove function?

I want to set a 800ms delay time to run a function , so I use a timer to handle it. The code is as following.But I found, at the first time, the function runs right, it just show only one console.log("here is console....."); , but when I click it again, it shows 2 consoles, and at the third click, it shows 3 consoles, and so on...

I cannot understand why this happens, can any friends explain it for me ?
