reverse engineering – Unknown file signature (zip?)

Has anyone come across the following file signatures?
It’s from an embedded system storing CAN databases.
I think the payload after the header is deflated (zip compressed data).

(sorry for the formatting, can’t attach it here.

Can Limit take limits of unknown functions?

For example when I input this

f[0] = 0;
Limit[f[x], x -> 0]

It does not output 0.

Is there a way to get it to output 0 in this case? For example is there a way I can get Mathematica to assume f is continuous?

spellchecker – Spell checking for unknown language

Lets say I am typing in a language mathematica does not recognize for any reason. How do make the software to understand that it should not try to spellcheck this notebook? It is annoying to see the entire workbook underlined.

Also I know this language is added, because others have it but don’t. Preferably I would like to in future for mathematica to use that languages spelling whan it does know the language.

Also, I dont want to do this for my interface only this notebook. So that when I share with students not everything is underlined.

differential equations – Solve PDE with contraints and unknown boundary conditions

I have a 2D PDE

mu = -0.1;
lambda = -1;
x10 = 0;
x20 = 0;
eq = {mu*x1 + D(h1(x1, x2), x1)*mu*x1 + 
     D(h1(x1, x2), x2)*lambda*(x2 - x1^2) == mu*(x1 + h1(x1, x2)), 
   lambda*(x2 - x1^2) + D(h2(x1, x2), x1)*mu*x1 + 
     D(h2(x1, x2), x2)*lambda*(x2 - x1^2) == 
    lambda*(x2 + h2(x1, x2))};

The definite region is {x1, -2, 2} and {x2, -2, 2}. The problem is that I don’t know the boundary condition of the PDE, but I do have a constraint that the gradient of h1 and h2 at point (x10, x20) is zero.

D(h1(x1, x2), x1)/.{x1 -> x10, x2 -> x20} == 0
D(h1(x1, x2), x2)/.{x1 -> x10, x2 -> x20} == 0
D(h2(x1, x2), x1)/.{x1 -> x10, x2 -> x20} == 0
D(h2(x1, x2), x2)/.{x1 -> x10, x2 -> x20} == 0

How can I approximate h1(x1, x2) and h2(x1, x2) numerically in Mathematica?

Unknown column in ‘where clause’ when using an alias for a subquery in MySQL

This simple query:

select exam.id as exam_id,
(select count(*) from dataset where dataset.id = exam.id) as n_dataset
from exam
where n_dataset = 0

returns the following error:

ERROR 1054 (42S22) at line 1: Unknown column 'count' in 'where clause'

Why?

seo – URL is unknown to Google – Will this still be indexed?

I am cloaking my website over a site I have developed in replit, but found a way to cloak over a pre-existing domain through managing DNS records and choosing a “cloak” method. This is a simple way to benefit easily from the domain without paying any extra cost, other than buying the domain name itself, which is what I have used.

I know a substantial amount of SEO and ranking, but never have used it. I am trying to get my page indexed by google, this displays this page after testing for a URL inspection.

Could this be a potential block due to “cloaking” as it could be used maliciously or is there any other way to do this in a similar way? Or use of CNAME to display over a domain?

The page is also very simple, mobile friendly design and does not have any other pages that may need to be crawled which is why something must be going on as it would have already been indexed for a page like this within 24 hours or less even.
enter image description here

However, on the status page of my website, it includes:
URL is unknown to Google and doesn’t provide much else information on about it.
enter image description here

Does this information seem normal to be “Not Applicable” as it just wasn’t indexed? then why would it say “indexing allowed? N/A” when it also displays it can be reached by google and “could” be indexed and selected as canonical.
enter image description here

I have done research about this issue, but most of them are old and outdated which doesn’t help or provide extended detail about the issue.
I just find it gets confusing as it says “URL is available to google” and it could be selected and scanned as canonical, on the other hand, some research shows that it won’t be indexed but never provides any other information about the issue.

The page is a portfolio site, which I am first practicing SEO on with all the the knowledge I have read from the guides that google has fully provided. But I need it to be indexed as a goal that I can use for further websites or highly informational websites I use or create in the future. Hope anyone here has knowledge about Search engine optimization, as the google support is always slow and I have tried to search for other communities but none were available.

Hopefully someone can give some reason or a detailed explanation of what is going on. Thanks!

magento2.3 – PHP: How to move an array element with an unknown key to end?

<?php $array = array(array
    (
        "value" => 4,
        "label" => "red",
    ),
    array
    (
        "value" => 5,

    ),
    array

        "value" => 6,
        "label" => "blue",
    ),
    array

        "label" => "yellow",
    ),
    array
    (
        "value" => 8,

    ),
    array
    (
        "value" => 9,
        "label" => "black",
    ),
);

foreach ($array as $key => $val) {
    if ($val("label") == 'blue') {
        $item = $array($key);
        unset($array($key));
        array_push($array, $item);
        break;
    }
}

print_r($array);

$val(“label”) change it on your need

Thanks
