Galileo | A Simple Modern Perl CMS | Content Management System library

I want to capture the image tag of MediaWiki format, e.g,

[[ Image:Justus Sustermans - Portrait of Galileo Galilei (Uffizi).jpg|left|thumb|upright|[[Galileo]] is often referred to as the Father of [[modern astronomy]], portrait by [[Justus Sustermans]]]]

I have to ignore the inner [[...]] to match the whole (shown by bold [[ and ]]). I came up with

I can't find a proper way of handling a multiple files input using Formik and React.

I've been trying to figure out the issue for days, but I still can't reproduce it outside of my web app.

I have a scrollable list that looks something like this: https://codesandbox.io/s/jolly-galileo-gk5x1?file=/src/App.js

When scrolling up, new items are loaded on top. I need flex-direction: column-reverse to scroll to the bottom as soon as the page is loaded.

The issue is that when a new item is loaded, it often scrolls up by a few hundred pixels. It happens when I scroll with a mouse or a trackpad on Chrome. It doesn't occur in Firefox, Edge, or Chrome when simulating touch using mobile mode. I couldn't reproduce it in the CodeSandbox link above and my web app isn't live yet.

Adding overflow-anchor: none didn't fix it. What are some other possible issues? I rewrote the c ode several times, so I think it's likely a browser quirk. Also, I don't think this issue occurred before I updated to Chrome 87.

Edit: Disabling smooth scroll seems to fix it. Still trying to figure out how to fix smooth scroll.

I'm still beginner with JavaScript and ReactJS.

I have a list that shows some numbers that the user typed. What I would like to know is how do I add the current value that exists in my array + the new value that the user typed.

For example, if there is a number 5 in my array, and the user types the number 3, I want to add these values and show them to the user. It is easier to explain through an image:

And here's my code.

Add New Value

You guys are my last hope, I spent more than 12 hours failing to solve the problem

The application was fully functional, until I made a modification and added controls

and moved the campground routes to Separate file "controlers" to make the the router file like this

This question is based on the paper What Every Computer Scientist Should Know About Floating-Point Arithmetic by David Goldberg. In the section 1.2 Relative Error and Ulps (page number 8), the paper gives an equation to calculate error in, ULP (units in the last place):

I've got a Jekyll private blog (i.e., laboratory notebook) that uses the wonderful minimal-mistakes theme. I make heavy use of tags for each of my blog posts and can see the list of tags.

I also like to keep track of the people I mention in my blog post, so I add additional meta data for each post like this:

I've got a nested field arrays setup use react-hook-form here. Take note that my actual code is a bit more complex, but the issue is displayed here just the same.

The issue I have is that if I delete an item in the list, say, ID: 2 in list [{ID:1}, {ID:2}, {ID:3}], the result isn't [{ID:1}, {ID:3}], but instead, [{ID:1}, {ID:2}].

Here's the official example, which gets nested fields array right.

Near as I can tell, the only difference is that my form relies on data that is retrieved from an API (in my example, handled by an async function) whereas the official example uses data that's already been initiated.

Looking at samples online, some make use of the field, but that just gave me more issues (in my actual code), and upon testing (in Code Sandbox), doesn't really change the fact that deleting 2 doesn't shift the entire array up.

Is there anything I'm missing?

I'm working with a recently purchased DragonBoard 410C running the Android 5.1 operating system and using Android Studio with Kotlin for generating a sample application that explores some of the hardware such as the 40 pin low power connector.

My question is how to access the 40 pin low power connector with the GPIO pins using Kotlin and Android Studio.

From my research thus far, it appears that the mraa library is the path to success however I have been unable to find any documentation on using the library with Kotlin.

How do I get started with the mraa library with Kotlin to access the 40 pin low power connector?

Or is there a different approach?

My first example is a simple blink the LED application however I have no idea as to how to access pins of the low power connector using Kotlin.

Notes and resources

mraa documentation page

Libmraa is a C/C++ library with bindings to Python, Javascript and Java to interface with the I/O on Galileo, Edison & other platforms, with a structured and sane API where port names/numbering matches the board that you are on. Use of libmraa does not tie you to specific hardware with board detection done at runtime you can create portable code that will work across the supported platforms.

upm library for mraa GitHub repository

The UPM repository provides software drivers for a wide variety of commonly used sensors and actuators. These software drivers interact with the underlying hardware platform (or microcontroller), as well as with the attached sensors, through calls to MRAA APIs.
