kandi X-RAY | lights Summary

lights is a C library typically used in Raspberry Pi applications. lights has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This project is a work in progress. There may be, and probably are, a few bugs. I would advise NOT installing in it’s current form, and instead wait for a stable release. However, if you are interested in collaborating/testing, please open an issue. While I have tried to make the code work for all, I can only test on my limited set of available devices. Some files contain paths which are hard coded for my personal system. Trying to build may result in errors. File paths and names may change from one push to the next, as may function prototypes. I will state this again, this is a work in progress. I’ve pushed the code for the benefit of testers, issue tracking and version control.

Is it possible to pull a single column from a csv using javascript?

Asked 2021-Jun-09 at 19:49

I am wondering if it is possible to pull a single columns values from a csv file using javascript?

Right now I have a designed Web page that will log the speed a status of some fans. All the data I am getting for the speed and status will be logged in a csv file. I am currently stuck on figuring out how to link and pull specific values from the csv. Here is the code I have a section of my page https://jsfiddle.net/IzzyStrauch/mtorf3eL/4/

I am trying to get it so that the csv values will change the numbers and lights.

I simplified your HTML and CSS to make the program flow a bit better.

First, you will need to parse your CSV. The most common conversion it to JSON. After you have your JSON, destructure or access the first item. After you have the first item, loop over the keys and determine if you need to set the value or the status. Once you have figured that out, query for and update the appropriate elements.

Change the mouse-select color in Jupyterlab 3

Asked 2021-Jun-07 at 12:31

I want to change the color of selected/highlighted text by mouse in input cells in Jupyterlab 3. I am using the light theme, however the highlighted text appears difficult to read in input cells. If I hightlight text with my mouse in the output cells, it is absolutely fine. Please see the attached image. Ideally I want both of my highlights have the same light blue color.

The extensions I am running are below. I have only 3 different themes - light, dark, and darcula. Jupyter lab is version v3.0.16. The complete stack is Jupyterhub with dockerspawner on Ubuntu 20.04.2. I am using Google Chrome browser on Win 10, the same problem happens in Edge.

Laravel App not running on xampp or live server but works well on php artisan serve

Asked 2021-Jun-04 at 07:52

My laravel app does not work on xampp or a live server but it works fine on the link provided by PHP artisan serve. Whenever I run this app on xampp it returns 404 error. I have other laravel apps also which work fine on xampp but this one. I am unable to find any solution to it that why my laravel is not running on a hosted server or xampp. I have tried all the solutions found in related questions but did not find any of those useful.

I have tried running the app after changing my existing .htaccess file in the root folder.
I have tried running the app after changing .htaccess file in public folder.
I have tried running the app after deleting both and one of them.
I have tried installing and updating the dependencies again using composer.

What should I do to make it running?

What I see when I try to run it through xampp is the errors, but the folder structure that always occurs when one runs a web app through it.

Right now, I have a single htaccess file which is in my root folder. Below is the code of it:

I've ran into this problem too. I've done some research and the only way I found possible to run Laravel on xampp was the following:

In the parent folder of the laravel setup, I created a folder called "laravel" and moved everything inside of it.
I went in laravel/public and took every file out of it, and I put it in the parent directory, resulting in the following folder structure: (in my htdocs)

Difficulty incorporating pointer lock controls API in three.js using es6 classes that are not modules

Asked 2021-Jun-04 at 00:51

As the title states, I am using es6 classes, but because they are all not modules apart from the main.js file, it makes it difficult to use API's because I cannot make use of import modules.

I used the code from this link's answer: How to add in Three.js PointerLockControl? and pasted the code into a js file, calling it up in my HTML, but I get an error stating:

Uncaught ReferenceError: PointerLockControls is not defined

It is not picking up the class when I reference it. I tried to link it to the GitHub raw code, and it didn't pick it up either.

This is my index.html code (only one line referencing the GitHub raw code):

Answered 2021-May-26 at 18:31

QUESTION

What does time_since_epoch() actually represent in a std::chrono::local_time?

Asked 2021-Jun-03 at 23:01

I'd like to serialize a std::chrono::local_time by sending it's time_since_epoch().count() value. My question is how is a non-C++ receiver supposed to interpret that value? Is it the actual number of ticks since the epoch at local midnight (1970-01-01T00:00:00)? What about daylight saving time changes? Is the time_since_epoch() bijective with the wall clock time? That is, can there be two values of std::chrono::local_time::time_since_spoch() that represent the same wall clock/calendar time?

I cannot find detailed information about the interpretation of std::chrono::local_time::time_since_spoch() at the usual places: cppreference, the latest C++ standard draft, or Howard Hinnant's date library documentation.

'Why even serialize a std::chrono::local_time?', you may ask. Well, a use case would be a building automation system that must perform a certain task at a given local time on a special day, regardless of timezones or daylight saving time. For example, "turn off the lights at 20:00 local time on Earth Day, 2021 (April 22).

EDIT: 'Why not serialize it as an ISO8601 date/time (without any offset), you may ask?'. I want to serialize it as a compact number using a binary protocol, such as CBOR.

The value in a local_time is the exact same value it would have in a sys_time. For example:

QUESTION

What is the difference between a constant buffer and a read only structured buffer?

Asked 2021-Jun-03 at 10:41

I would like to know which resource type is the best to use in order to hold as many elements as possible for data that will be static and not change for the duration of a draw call. The only difference I can tell between a constant buffer and a read-only structured buffer is the fact that constant buffer data has to be 256 bytes aligned inside of its ID3D12Resource object.

ANSWER

Answered 2021-Jun-03 at 10:41

There are more differences between constant and structured buffers.

In a constant buffer, Only 64k of data can be visible at the same time, so you can't have 1mb of data and have it visible at once in your shader, whereas it is possible on structured buffers.

Constant buffers have more complex alignment rules than structured buffers, you example actually fits it pretty well:

In case of a structured buffer, your light struct has a size of:
