I cannot pass Story #5: "When I click a .nav-link button in the nav element, I am taken to the corresponding section of the landing page." I have all of my href attributes set to the corresponding id attributes and when i click on them they take me to the correct section of the page, but I am still failing this test... What am I Doing Wrong???

The code I wrote is below:

Wracking my brains on this one but I'm sure it's just my inexperience with js.

I have a list of items and I am trying to create an eventListener for each item row so when I mouseover the row some icons will appear. The icons should hide again on mouseout.

I am using setAttribute to change the opacity of the elements on mouseover and mouseout events.

My problem is after the loop runs to create the eventListeners the setAttribute only affects the very last row of the loop - regardless of which row I mouse over.

I have a JSFiddle here which shows you the exact behaviour (better than I can explain): https://jsfiddle.net/Finno/ds9q7zju/27/

Note: this is a simplified example but it exhibits the same behaviour. My real app has the items formatted in a drop down menu.

Here is the code :

Python version: 3.9.1

Hello big brains!!

I trying to write bot that send requests and it work perfectly fine, the only issue that i have is when i trying to use web debugging programs such as Charles 4.6.1 or Fiddler Everywhere. When i open it to see bot traffic and response form server it crash showing me this error:

(Caused by SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1124)')))

i used to have this issue by i was available to fix it by simply adding "verify=False" to my request post but right now it does not work and i try a lot of things to fix it but nothing help and i have no idea whats wrong.

Having made a program which streams PNG images to the browser by means of a multipart/x-mixed-replace Content-Type header, I noticed that only the frame before-last is displayed in the tag, as opposed to the most recently sent one.

This behaviour is very annoying, as I'm only sending updates when the image changes to save on bandwidth, which means that the wrong frame will be on screen while I'm waiting for it to update.

Specifically, I am using Brave Browser (based on chromium), but as I have tried with both "shields" up and down, I assume this problem occurs also in other chromium-based browsers at least.

Searching for the problem yields only one relevant result (and many non-relevant ones) which is this HowToForge thread, with no replies. Likewise, I also thought the issue is to do with buffering, but I made sure to flush the buffer to no avail, much alike to the user in the thread. The user does report that it works on one of their servers though and not the other, which then lead me to believe that it may be to do with a specific HTTP header or something along those lines. My first guess was Content-Length because the browser can tell when the image is complete from that, but it didn't seem to have any effect.

So essentially, my question is: Is there a way to tell the browser to show the most recent multipart/x-mixed-replace and not the one before? And, if this isn't standard behaviour, what could the cause be?

And of course, here's the relevant source code, though I imagine this is more of a general HTTP question than one to do with the code:

I code mostly client-side these days, so my PHP is rusty and I would prefer a pure PHP design in this particular case.

I don't need any client -side code for this. I want to read a lot of text files, extract some data and insert it to a MySql database.

1. this could potentially take quite some time, so
2. I want to echo() some indication of progress. Also,
3. I am concerned that it might take longer than the default 30 seconds, but I don't like to mess with that limit, in case my script hangs.

In order to do #2, I would normally use header('Refresh:1');, but what if that refresh happens in the middle of the MySql INSERT operation?

I suppose that before INSERT, and on page reload, I could just COUNT MySql table entries, to determine where begin processing the next text file.

Alliteratively, I could reload the page every few iterations of the loop, after the INSERT has been done, but how, since I could not use header('Location:X'); as I have already echo()ed the progress. Perhaps I could somehow fake a form submission? But, that feels hacky.

This seems to be a generic design pattern and I am sure that better brains than mine came up with an elegant solution long ago. Can someone tell me what that solution is? Preferably pure PHP. I have searched, but can't find anything.

At the moment, I am going with a JS solution: echo '';, but would prefer a pure PHP

This is my website. I'm currently working on multi-choice filters, or rather on resetting them. There is no problem on PC. Click the X button and it clears the filter

But the same simple thing doesn't work like this on mobile devices. I don't understand why. You need to click an area below the X button, well below, to dismiss the filter. This is how you need to click to make it work

Also, I just realized that when clicking like this there is an error in the console. Error in the console after successful dismissing

I'm testing the mobile behavior in Opera (PC version, last update) using the Inspector with mobile simulation; the device is irrelevant. You can try it too.

The same behavior occurs on an actual android, both in Chrome and Opera.

Side notes!

1. If you activate the dropdown search in any multichoice field, while it's visible, the close buttons work perfectly well and precisely on mobiles. (Although the behavior of this dropdown panel is weird too. It does not always drops down when focusing on a field, as it does on PC.)

2. When I tried to locate the close button using the console and Jquery and then applied .click(), it worked. So I guess the problem doesn't lie in JS.

3. If you want to test it on a phone choose the Desktop site. On the mobile view, though, another peculiar thing occurs-the blue X button to the right of the field doesn't work.

PS. I've been wracking my brains for 3 hours to solve this mystery, yet no result. Please help!

I'm running Ansible 2.7.9 on Red Hat Linux 7.4. In my playbook, I need to combine information in two yml files into one data structure that I can then iterate over in a task.

For example, in one .yml file I might have:

I have a dataframe containing materials, dates of purchase and purchase prices. I want to filter my dataframe such that I only keep one row containing each material, and that row contains the material at the latest purchase date and corresponding price.

How could I achieve this? I have racked my brains trying to work out how to apply aggregation functions to this but I just can't work out how.

I have this code:

It looks like this:
