What means FP in CrUX Community Dashboard? - chrome-ux-report

CrUX Community Dashboard provides on the page 7 metric named FP / First Paint. But I can't find at web.dev any metric with this name.
However, under web.dev there is a metric named First Meaningful Pant. On comparing First Paint and First Meaningful Paint, one realizes,
First Paint on the page 7 of CrUX Dashboard has following ranges: Good (< 1s), Poor (>= 3s),
while First Meaningful Paint's ranges, listed at web.dev, are: Good (< 2s), Poor (>= 4s).
Is it an error in the CrUX Community Dashboard and Firts Paint should be First Meaningful Paint? Or miss I something?

CrUX metrics are defined in more detail in the official docs, for example First Paint is defined as:
First Paint reports the time when the browser first rendered after navigation. This excludes the default background paint, but includes non-default background paint. This is the first key moment developers care about in page load – when the browser has started to render the page.
— Paint Timing API
See https://web.dev/first-meaningful-paint/ for more info on FMP, which is now a deprecated metric.

How to display input values to ionic grid?

I am new to Ionic and I am trying to do this, I want to pass the value from my input to my ionic grid. Can anyone give me an idea on how to do this? Thank you for answering.
First you need to get first name value and last name value as form data. Then add it to an array. In Html side you can loop that array and value can add to the rows of grid.
Check this angular tutorial to get clear idea

I think you should learn angular instead of ionic/react, here is why...
[the following is a personal opinion from personal experience]
I started learning ionic react but by the time I had finished the documentation and my project, I left having learned nothing. This half full feeling. It was odd that I couldn't fully grasp a simple object class container language as I program almost every day of the year for fun. I couldn't figure it out, it bugged me for a while but I took the L.
a few months pass and then I begin learning Angular as a second attempt at hybrid PWAs.
Having used Angular and Ionic/React, Angular blows Ionic/React out of the water when it comes to learning and understanding the material. Angular s docs are well orchestrated and the framework is as enjoyable as it is popular.
Comparing Official docs between Angular and Ionic.
Ionic/react documentation demos were outdated making it impossible to follow the example code vs the interactive demo
Ionic/react documentation is unreliable. at the time it was a gamble between 'updated', 'outdated','missing-information' (makes it impossible to build a proper project)
Angular's documentation is updated, accurate, thorough and overall superb
Angular has a greater online presence with an active online community, Q and A.
Easier to work with, less headaches, constant updates
Ionic documentation is a travel brochure.
Angular documentation is a map.
If you are going hiking in the woods, do you want a map or a travel brochure?

Ebook with Ionic 3

Working with latest version of Ionic (3.x). I am working simply on programming an Ebook with almost 200 pages (in 4 languages).
I find not good to embed the whole html textes in a one <ion-content>. So I thought about a solution more sophisticated, such as dividing into chapters, so I am between 2 solutions (none of them works btw).
1. Use ng-include which after hours I found out that it is not more supported in Ionic (I hope I'm wrong).
2. Create a component for each chapter (the template is the chapter text wrapped in HTML). But I think that this one is performance-costly because at program launch there will be creation of many views of the components.
Any better advice?
I don't think I would try to load the entire book's content into the app. I would fetch content on an as-needed basis. You also need a solution that will scale with size of the device display, so the one-component-per-chapter idea is probably not the best choice.
(Additionally, I would take a step back and ask why the book isn't being distributed on already established platforms, e.g. mobi, ePub, etc. But this is outside of the scope of your posted question, of course.)

Some elements are not showing in openstreetmap

I added a point on openstreetmap several months ago, and that point is not showing in the standard layer (or any other layer).
When I click on the interrogation mark, I can see that the point exist in the database, but no icon is showing for that point :
If someone can tell me why this is happening (because it is not the first time), I will really appreciate it.
Here are also the point link https://www.openstreetmap.org/node/4541228705 to verify by yourself if you want to.
Not all POIs are shown on the standard layer. This can have several reasons:
The POI is too unimportant to display it.
The POI hasn't been added to the renderer stylesheet yet.
The POI is in the stylesheet but not in the renderer database and a re-import of the database would be necessary.
The POI is in the stylesheet and the database but there is not enough space to show it.
Your POI is tagged as office=association. Currently the office key is not rendered on the standard style. There is already a [corresponding issue for openstreetmap-carto (the current default rendering style).
In other words: You did everything right. The reason for the office not being rendered is not your fault. Unfortunately you have to wait until the rendering stylesheet gets updated (you might participate in the mentioned issue to speed things up). Do not change the tagging just to make it appear on the map (also called tagging for the renderer). The good news is: Geocoders / routing engines will find your office nevertheless (e.g. Nominatim)! There might even exist other OSM-based maps with a different stylesheet that already show your POI.

Charts with DevExpress / DevExtreme

Hi I'm searching for a good chart plugin for my web-application, which can solve some of my requirements. To date, I've tested follow chart plugins:
Kendo UI
FusionCharts
HighCharts
Angular Charts
The plugin highcharts solves all of my requirements, but it's really expensive. The others don't solve all of my requirements, so I have to search another one. The solution of a hand-made chart needs a lot of time and that means for our company, it's also expensive. Now I've found the framework DevExpress. Before I invest a lot of time to test it, I would like to inform myself, if it's possible to make charts with DevExpress with this requirements:
Any number of y-axes with various values
Events (detect if clicked for example)
Costume style with css (I think I saw it on their website)
Integrate it as HTML in custome code
Supports JSON
Mixed line-style (for example, a part of a line in the chart is solid, another is dotted, but it's the same line)
Responsive Design
My results with highcharts:
Any number of y-axes with various value types:
Mixed linetypes in same line (blue line):
Special chart constalations:
This special requirements are for the healthcare, because they have some weird and special charts they need for checking medical results. So it's simply complicate, to find a good plugin. If there is someone who has a knowledge with DevExpress and charts and can answer me I would be thankfull.
Cheers.
Any number of y-axes with various values
DevExtreme has Multiple Axes Demo
Events (detect if clicked for example)
DevExtreme Charts have handlers for events. Here is a demo illustrates onPointClick
Costume style with css (I think I saw it on their website)
See it in Appearance Customization Article & Customize Points and Labels demo
Supports JSON
Remote Data Source Using an Ajax Query Demo
Responsive Design
DevExtreme Charts looks good on phones, tablets and desktops (Mobile & Web)

Activating multiple versions of a page in AEM over time

In AEM (Adobe Experience Manager), I'm trying to schedule the activation of multiple versions of a single page that have slightly different content each day. So, while I'm out-of-office on Saturday morning, the "Saturday" version of the page is auto-activated. Then on Sunday morning, the "Sunday" version of the page is activated. On Monday morning, the "Monday" version of the page is activated, and so on. So far, I've only been able to successfully schedule a single change, not multiple changes over time, as described. Any help would be appreciated.
I don't know a way to directly do activation of different versions at different times, but an alternative you could consider would be to create the portion(s) of the the page you to change over time as a teaser component, then use segmentation to define time-based segments that would cause the page to render those portions differently depending on the date/time.
Check out this documentation: https://docs.adobe.com/docs/en/aem/6-1/administer/personalization/campaigns/segmentation.html. It states
"...segments are then used to provide a visitor with specifically
targeted content."
This wouldn't be a typical usage of segmentation, but it is a way to accomplish what you want to do. In step 6, when creating a new segment, you would need to define a JavaScript expression that evaluates the date/time to resolve the segment to true/false. You could define several such segments for each date/time you need, then depending on which segment resolves to true different content would be shown.
This has overview info https://docs.adobe.com/docs/en/aem/6-1/author/personalization/campaigns.html and says that
"Typically a teaser page is a temporary action that will last for a
specific period of time, until it is replaced by the next teaser
page."
At least from AEM 6.3 (I didn't check the earlier versions, but quite sure it works the same way) there is "Scheduled publication" function.
When you schedule the page for activation the snapshot version is created and that very version will be published, even if the page itself was changed since then. And this can be used for several times. So actually you have what you need works out-of-the-box.
I would suggest you to investigate /etc/workflow/models/scheduled_activation/jcr:content/
for more information.
