Google Mobile Friendly Test does not reliably load css / js / images (cloudfront + ALB).

I use CloudFront and ALB with AWS, and my website always looks great on mobile, desktop, and tablet browsers.

In the Google tool for mobile phones, however, there are often no random images, CSS and Javascript

TEST URL: (ALB + Cloudfront) (Error with js / images / css randomly)

https://search.google.com/test/mobile-friendly?url=https%3A%2F%2Fphppofofsale.com%2F

EC2: (Never mistakes on my CSS / Js, images)

https://search.google.com/test/mobile-friendly?url=https%3A%2F%2Fwebsite.blastohosting.com%2F

What could be the cause? I've looked at cloud logs and they all have status 200 and it seems the requests never make it into the cloud front. My website works fine except for this test

Is there a semi-automatic way to clean up / dev / loop mounts?

My system seems to generate more / dev / loop mounts for certain updates.
So far it looks like this:

Is there a tool that can detect which ones are no longer used and release them? Not that this causes a problem, I prefer less clutter with mount points.

Vector analysis – Equivalent definition for multi-variable functions

Say a function $ f: B (x; r) rightarrow mathbb {R} ^ q $ is a constantly differentiable feature with $ | Jf (x) | leq c $ for all $ x in B (x; r) $, I want to show this $ | f (x_1) – f (x_2) | leq c | x_1-x_2 | $ whenever $ | x_1-x_2 | <r $,

I'm having trouble integrating the Jacobian $ Jf (x) $ to prove it, since it is not one-dimensional.

Use Google Photos Cloud instead of Adobe CC for Lightroom CC Storage

With Lightroom CC, all your photos can now be stored in Adobe's Creative Cloud. However, this only allows 100GB of free photo storage. Google, however, offers Google Photos, which offers free unlimited "high quality" photo storage.

Is there a way to seamlessly use Google Photos with lightroom CC?

I'd like to be able to take photos from Google Photos and use them directly in Lightroom for editing, and so on. Essentially, Lightroom's CC memory is being replaced by Google Photos.

Here is what I think …

A few possibilities are possible.

  1. A user has created a plugin for Lightroom CC to work with Google Photos

  2. Save photos on the desktop with Google "Backup and Sync" and
    Use this library in Lightroom

Does anyone have a current solution or a better idea?

html – Tumblr Hide Post Information & Install Theme Button

I would like to know how to hide or delete the Install Theme button on the top right corner and the Credits button on the bottom right corner of my page.
I also want to know if it is possible to hide these boxes below my posts (this disturbs my grid theme):

Enter the image description here

I tried a few tutorials, but none of them worked for me.

Here is the link to my Tumblr so you can see the HTNL code.
Hopefully someone can help me! 🙂

centos7 – CentOS VitualBox downgrade

I received a Linux CentOS 7 host for virtual machine environments, mostly Windows. I use VirtualBox with Vagrant to build the machines. Lately, I've upgraded both: VirtualBox from 5.2.18 to 5.2.22 and Vagrant from 2.2.0 to 2.2.1. After doing this, Vagrant will not communicate with the winrm Communicator to set the network adapters ip, which gives me the error:

"Timeout waiting for the machine to start, which means that
Vagrant was unable to communicate with the guest computer on the Internet
configured ("config.vm.boot_timeout" value) period "

I tried to solve this problem by changing the config.vm.boot_timeout and config.winrm.timeout values ​​unsuccessfully.

I want to downgrade the Virtualbox to the previous version. How can I do that in CentOS 7?

PD: The host has no GUI.

Thank you in advance.

Asymptotic – Great O space complexity of this method is Anagram

I'm discussing with some friends just how big the complexity of the Big O space of this isAnagram method is:

public boolean isAnagram (String firstWord, String secondWord) {
if (firstWord == null || secondWord == null || firstWord.length ()! = secondWord.length ()) {
return it incorrectly;
}

map charCounts = new HashMap <> ();
for (char c1: firstWord.toCharArray ()) {
if (charCounts.containsKey (c1)) {
int currentCount = charCounts.get (c1);
charCounts.put (c1, currentCount + 1);
} else {
charCounts.put (c1, 1);
}
}

for (char c2: secondWord.toCharArray ()) {
if (charCounts.containsKey (c2)) {
int currentCount = charCounts.get (c2);
if (currentCount == 0) {
return it incorrectly; // no anagram if it has more than one character as the first word
}
charCounts.put (c2, currentCount - 1);
} else {
return it incorrectly; // no anagram if it contains another character
}
}
return true;
}

This is a conflict point because the space used by the method does not depend exactly on the input, but rather on a property of the input, namely the number of unique characters in the first word.

Suppose m is the length of the first word and n is the length of the second word. Let's assume k is the number of unique characters in firstWord.

Some of us believe that the space complexity is O (k), essentially the number of entries in the map. That is, k is the upper bound for the space used because k is the number of entries created in the map, one entry for each unique character.

Some think it's basically just O (1) complexity, because although the map is dynamically dimensioned in reality, we might also consider it as O (1) and actually populate the map with a count of 0 for all Alphabet. The argument, on the other hand, is that you do not know "any alphabet" if the Latin alphabet consists of 26 characters but ASCII has 128 characters and Unicode> 137,000 and other fonts, who knows.

Others argue that we should only consider m, the length of the first word. In some cases m < k, because it is shorter than k. In the worst case, m > k (because of double characters) and m in very long strings the choice of the type of card values. e.g. The specified code uses "integer" or 2 ^ 32 sizes, but for very long strings, you may need to go to 2 ^ 64 or more. In any case, this argument asserts that m is a factor in the scaling of the algorithm and should therefore be O (m).

A derivative of this last argument is that, on average, for any given character, there are m / k occurrences of that character in the string, and therefore the size of a m / k value in the computational space is log (m / k), a close Big O is O (k * log (m / k)).

Does anyone have any thoughts?
