kandi X-RAY | Smooth Summary
Smooth provides a set of classes that makes life as a developer easier compared to working directly with ESP-IDF & FreeRTOS APIs. An application built with Smooth is entirely event driven and thread-safe*. Smooth utilizes the power of FreeRTOS, but hides all the complexities from the application programmer. Traditionally, embedded systems require a fully static memory footprint after start-up. Smooth takes a somewhat more pragmatic view on this; it utilizes the standard library (which is not memory static) to provide cleaner code, at the cost of some extra used bytes of RAM. However, where it is appropriate, such as with the queues, things are designed so that the result is a memory static instance, i.e. a smooth::ipc::Queue will have a memory static footprint once initialized. mock-idf provides the ability to compile even applications that uses ESP-32 hardware for Linux with the only consideration that the mocks do not actually simulate the hardware. *) To certain limits, of course.

QUESTION
I'm trying to push my first docker image to ECR. I've followed the steps provided by AWS and things seem to be going smoothly until the final push which immediately times out. Specifically, I pass my aws ecr credentials to docker and get a "login succeeded" message. I then tag the image which also works. pushing to the ecr repo I get no error message, just the following:
...ANSWER
Answered 2022-Jan-02 at 14:23I figured out my issue. I wasn't using the correct credentials. I had a personal AWS account as my default credentials and needed to add my work profile to my credentials.
EDIT
If you have multiple aws profiles, you can mention the profile name at the docker login as below (assuming you have done aws configure --profile someprofile at earlier day),

QUESTION
When I read data from GPS sensor, it comes with a slight delay. You are not getting values like 0,1 0,2 0,3 0,4 0,5 etc, but they are coming like 1 then suddenly 5 or 9 or 12. In this case needle is jumping back and forth. Anybody have an idea how to make needle moving smoothly? I guess some kind of delay is needed?
Something like, taken from another control:
...ANSWER
Answered 2022-Mar-21 at 22:09Coming from a controls background, to mimic behavior of an analog device, you could use an exponential (aka low-pass) filter.
There are two types of low-pass filters you can use, depending on what type of behavior you want to see: a first-order or second-order filter. To put it in a nutshell, if your reading was steady at 0 then suddenly changed to 10 and held steady at 10 (a step change), the first order would slowly go to 10, never passing it, then remain at 10 whereas the second order would speed up its progress towards 10, pass it, then oscillate in towards 10.
The function for an exponential filter is simple:

I am having problems with npx create-react-app involving global installs. My confusion arises because as far as I'm aware the create-react-app package is not installed on my machine.
Some Details:
I start a react project (with typescript template) as I have previously and recently done on this same machine a number of times:
npx create-react-app --template typescript .
I get this prompt from the terminal
Need to install the following packages: create-react-app Ok to proceed? (y)

I have the following code:
...ANSWER
Answered 2022-Jan-03 at 22:23You need to play around with the animation duration and also adjust the key frames percentages -> the tween in when you are flipping the text using your transform/opacity rules.
I have slightly adjusted each, but this comes down to a taste in how you want it to look and feel. Spreading the flipping animation over more of a percent (your tween) will lessen the amount of time you have in a pause between animations.

I have a simple on-hover CSS animation which makes slide transition between images.
When the user makes the hover on SECTION ONE and before the animation ends make hover on SECTION two, animation restart and make lagging move.
MY CODE:
...ANSWER
Answered 2021-Dec-28 at 10:00I think that problem is because "moving circle function". Moving dom element with Left and right is not good for performance. You should move the circle with "transform". transform runs with GPU acceleration and it performs better and make move smooth.
Try this code.
QUESTION
I am looking for a way to detect if the device I am using can support Dolby Atmos sounds.
After searching around I found this call.
https://github.com/w3c/media-capabilities/blob/main/explainer.md#spatial-audio
...ANSWER
Answered 2021-Dec-24 at 06:57Detecting the codec doesn't necessarily detect whether the system can support Dolby Atmos
Correct.
What reliable way is there to detect if your system will truly support Dolby Atmos whether its with a receiver or a Dolby Atmos compliant sound bar.
Unfortunately, this undetectable from the browser.
The browser itself and even the OS doesn't always know what is downstream. Sorry for the bad news!
