## Is that possible to remove the word “nginx” from default 404 page footer?

I knew I could remove the nginx version by using `server_tokens off;`.

I knew I could modify the nginx header by using `more_set_headers 'Server: myserver';`

I knew I could setup custom 404 page by using `error_page 404 /error/404.html`.

But what if I don’t want to use custom 404 page, I just want to use the default 404 page but removing the “nginx” word in the footer? Is that doable?

I am using `nginx-extras` package in debian.

Thanks a lot.

## plugins – I want to remove the register/login WordPress top bar from my website

enter image description here)1,

This screenshot above shows the functions.php code snippet I tried to use to remove WordPress register/login top bar from my website but so far it haven’t worked. I included the code into a WordPress plugin called code snippets.

(I included the custom code to code snippet WordPress plugin because I wanted to to add content to my themes functions.php file without directly editing my themes files)

Please advise how I can get this code to work and remove WordPress user register/login top bar from my website 🙏 🙏🙏🙏

## After removing text from file, how to remove empty lines from file using python

I am removing content from file and rewriting using python
This is the initial script

``````[Property file]
host1=0.0.0.0
host2=1.1.1.1
``````

I am changing host values.After changing through python script script, white spaces are creating

``````[Property file]

host1=0.0.0.0
host2=1.1.1.1
``````

Everytime I run script it creating more spaces.Can anyone suggest an idea. Thanks in advance

## simplifying expressions – Remove specific terms from Mathematica output

I have a very complicated output from Mathematica – which may run to several pages – and I want to keep only some of the terms.

The expression I am working with is a double summation. It results in (several pages) of output, but many of the terms include variables raised to a power where the power is a function of $$n$$. For example:

``````$$begin{equation} a^4b^2(2a^3+a^7-4abc(6a-9)+a^{2n+6}left(8+9bc-6a^{2n-8}right)) end{equation}$$
``````

In my problem, $$n$$ is very large, such that I want to be able to ignore any individual terms involving this power because they become negligible. The expression above would become:

``````$$begin{equation} a^4 b^2 (2a^3 + a^7 - 4abc(6a-9) ) end{equation}$$
``````

Any assistance gratefully received – I have about 5 pages of output to sift through otherwise!

I have looked at this post

and have tried the delete with function suggested, but
it removes all of the terms in the above example.

Here is a small sample of the Mathematica Output I am trying to simplify:

## draw.io – How can I remove the toolbar?

Can someone explain to me how to remove the toolbar ? there is only the option ” toolbar-nohide=true” which makes the toolbar always displayed or disappear when the cursor moves away.
I tried custom css but without any effect.
Here is a code fragment:

``````<div class="mxgraph" style="max-width:100%;toolbar:display: none; border:0px solid transparent"
``````

## Clean way to remove an identical nested object in javascript

can you give me some feedback about my approach to remove an idential element from following data structure?

``````const items = {
'Sun Mar 07 2021': (
{ id: 2 },
{ id: 1 }
),
'Sat Mar 06 2021': (
{ id: 1 } // remove me
)
}

const id = 1 // filter by id 1
const newDate = 'Sun Mar 07 2021' // filter by newDate

let oldDate = ''
// Find the duplicate date and
// save it in oldDate to splice it afterwards
Object.keys(items).forEach(date => {
items(date).forEach(item => {
const match = item.id === id
if (match && date !== newDate) {
oldDate = date
}
})
})

// remove the old item from matched array
if (oldDate) items(oldDate).splice(item => item.id === id)
``````

I think it can be simplified or solved differently. Unfortunately I can’t get any further, do you have any ideas?

## I will remove background of an any image for \$5

I can remove any background of a picture

high quality

5\$ for 5-10 pieces (depend on you)

for each additional image you need to pay 1\$ or make a new order if you have another 5-10 or a lot.

## Remove Default Block (Based on Post Format) Added When Creating a New Post

I’ve been trying to search for a solution but I can’t seem to find a clear reference or a guide on how to do this.

On my website, I have the Post Formats (Standard, Video, Gallery) enabled and I have Video as the Default Post Format set in Settings > Writing.

Now, when I create a new post, a Video Block is added by default to the post and whenever I change the default post format, a block that corresponds to the post format gets added automatically upon creation of a new post.

I understand that this could be helpful in some cases but I prefer not having these default blocks and if I have to choose, I would prefer having a Paragraph Block added by default.

I am not sure if there is a setting available for this or I might need a filter to override this setup. I was able to do some things like get rid of some default panels in the admin but for this one, I can’t seem to find any resources.

Thanks in advance for the suggestions!
