links | Experimental content sharing and collaboration platform | File Sharing library

When using ls -l, I noticed that directories start with 2 hard links, and gain one for each subdirectory. I understand that the current directory link . counts as one link and the parent directory link .. of each subdirectory counts as a hard link, but:

1. Why don't subfiles count towards hard links when subdirectories do?

2. Why does the parent directory link .. count as a hard link for both this directory and the parent directory?

I want to create components dynamically with custom Refs , and I want to use those refs and use with functionalities like measure() etc.

I created following code

I have two functions one thats triggered on a mouseenter event and the other on mouseleave. Both of these functions are repeated three times.

On mouseenter the classlist "active" is addded 5x and the text content is changed. On mouseleave the classlist active is removed 5x and the text content is set to an empty string, and the original image is displayed again.

When the mouseenter event listener is triggered, Depending on which image is being hovered (3 images).
the text content property that gets added various between the three "Photosnap" "Dine" "Nike".
As-well as the background color that gets triggered various between "red" "blue" "pink".

Hover state shown as red left image and normal state shown as right image
-The image shown here is one of three. It is displayed with a red background and the text content of "photosnap".
-The other with a blue background and the text content of "Dine".
-The third and final with a pink background and the text content of "Nike".

I hope this paints a clear picture i am having a hard time making this a code snippet.

I am trying to refactor this javascript so its not so repetitive. I'm new to javascript and having a hard time getting this to work as something other than what i currently have. I'm not clear on how to make a function that i can call inside of other functions to cut down on the repeated code. Or possibly use the "this" keyword ?

Javascript--

I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.

CountryDetails.js

I'm using the plugin just_audio: ^0.7.4 from https://pub.dev/packages/just_audio. This plugin works with a system of playlist, we define a playlist this way (example with 3 songs):

Hey to all in the forum

I use JSF Mojarra implementation, version JSF 2.2

I need desperately a help on this.

1. I have a snippet of my page.
2. I have a custom component "example_result.xhtml" used in the page.
3. I have my BackingBean.java Be aware please that this code is not the real code I made. If you run it, it will be very ugly maybe because I deleted all the css classes and I kept only the hot stuff I need to show you my problem.

Everything is inside 1 form.

The 5 "h:selectManyCheckbox" (in my code I have 8 or 9)

In the form I have 5 "h:selectManyCheckbox" which are using values in the "value" attribute for different cases (javaFrameworks2Values, javaFrameworks3Values,...), and the "f:selectItems" use arrays of "SelectItem" (javaFrameworksSelectItems2, javaFrameworksSelectItems3...) created for these different cases, just to make some examples for me to understand how all the selectOne and selectMany components work. The ideas for this, about different cases were taken from these links: "https://stackoverflow.com/tags/selectonemenu/info" and "https://mkyong.com/jsf2/jsf-2-checkboxes-example".

After I have 2 commandButtons

1 for submit, and 1 for reset the values.

Display the values

After I display the results of the values of the "h:selectManyCheckbox" via the "example_result.xhtml".

You can see the 4th "h:selectManyCheckbox" that is the only one different, because it has the attribute "required" with the attribute "requiredMessage". With it there is a "h:message" to display the validation error.

In the BackingBean (which is Spring Bean, but it works perfectly good - sorry I don't want ejbs 3.x), I have initialized:

1. The values of the SelectItems and
2. The values of the "value" attribute, where the values of the "h:selectManyCheckbox" will be stored to be displayed later. [The code is completely castrated, to make it readable snippet].

When the page is rendered, I select checkBoxes (e.g. the 2 last, because the 2 first are initials) from all the "h:selectManyCheckbox". When I say that select from all, I mean it. And from the 4th with the "required" attribute. I try in the buttons (see in the code) the "Effort 1", or "Effort 2", or "Effort 3" (in the "f:ajax" in the buttons) and the result outputs in the last part are displayed and updated like a candy. Without any problem. To achive this with the composite component I googled and tried a lot. But I made it.

Then it comes the time to try the 4th to see the validation error of the "required" attribute.

I select again from all as before, but not from all. NOT from the 4th "h:selectManyCheckbox" this time. I select nothing from the 4th "h:selectManyCheckbox" to ckeck the validator error message ("requiredMessage"). The result is: It displays the message of error (GOOD until now), BUT this time it does not update anything from the others "h:selectManyCheckbox" to the output results at the end, and it does not reset the values as well as it was doing before (when I selected from all and from the 4th as well).

I understand that it says: as long as in the form the 4th failed with validation error, all the other "h:selectManyCheckbox" will not update the output results (something like wanting to fail all the others too).

But what really happes here?

1. It does not give the values to the "h:selectManyCheckbox", to be updated to the output?
2. It gives the vales to the "h:selectManyCheckbox" normally, BUT it just not updates the output?

The other efforts in the "f:ajax" in the buttons, are just efforts maybe to solve the problem but in these cases they don't even display the error message in the 4th case and of cource they don't update the other output results as well (again). But no message error as well.

I don't know if the problem is clear to you. I can explain in the discussion better so I can clarify the situation better. [To be honnet it took me 1 and half hour to write all this thing]

Thanks a lot in advance

========== Snippet from my page ==========

I am building an app following the Rest Countries API challenge from frontendmentor. I have run into a problem. When trying to find the border countries full name using the alpha3code, I get the error : TypeError: Cannot read property 'name' of undefined.

Im working in a menu where the current section is gonna be select it on scroll, but when i try to get the offsetTop of the elements i get alway 0 for some reason, on the parentElement a get value for offsetTop but in this case does not work for me using the offsetTop of the parentElement because i have many childElements inside with different offsetTop.

I'm doing some scraping, but as I'm parsing approximately 4000 URL's, the website eventually detects my IP and blocks me every 20 iterations.

I've written a bunch of Sys.sleep(5) and a tryCatch so I'm not blocked too soon.

I use a VPN but I have to manually disconnect and reconnect it every now and then to change my IP. That's not a suitable solution with such a scraper supposed to run all night long.

I think rotating a proxy should do the job.

Here's my current code (a part of it at least) :
