Cannot get State & Result Of Remote Celery Worker

5 (broker)

Redis (backend)

Flower

Celery default worker

Webserver application
slave-machine1:

Celery default worker
slave-machine2:

Celery default worker


I'm triggering tasks via Webserver application (from master-machine), for example:
task_id = task1.I have an API for retrieving the task status / result (again, from master-machine):

result = task1.

Exclude Checkbox from anchor HTML/CSS

pid=1'>
<li>
<input type='checkbox' name='chkproject' value='project'/>&nbsp;&nbsp;&nbsp;&nbsp;Example
</li>
</a>


This works perfectly in Chrome and I can check/uncheck the checkbox without triggering link click.But in firefox, when I click on the checkbox, link click triggers and browser directs to the link.

parse error, expecting `'&'' or `"variable (T_VARIABLE) on git pre-commit hook

I have a git pre-commit hook that works fine on the command line however when I try using it as a hook it gives me:

Parse error: parse error, expecting `'&'' or `"variable (T_VARIABLE)"' in /Users/jini/apps/laravel_apps/lawyermetrix/vendor/laravel/framework/src/Illuminate/Foundation/helpers.php on line 478


I did some research and checked that I was running everything on PHP 7

MY Pre-commit hook:

React Component won't render after Jquery Ajax Call

ajax({
url: url,
headers: { 'Accept': 'application/javascript' },
dataType: 'html',
beforeSend: function(){
$('.PostButton\" data-react-props=\"{&quot;buttonText&quot;:&quot;Contact me&quot;,&quot;buttonClass&quot;:&quot;btn btn-clear btn-block&quot;,&quot;business&quot;:{&quot;id&quot;:86055,&quot;business_name&quot;:&quot;Buy Plan&quot;,&quot;mobile_phone&quot;:&quot;0412 345 678&quot;},&quot;cta&quot;:&quot;card&quot;,&quot;slideTitle&quot;:null,&quot;showPostJobExclusively&quot;:true,&quot;showToAll&quot;:false,&quot;CallCustomer&quot;:false}\"></div>


but react component did not render.

API interface with only 100 to die, and don`t know how to optimize?

The server configuration is as follows:
Ali cloud ECS: cpu 2 nuclear, memory 8g,
Ali cloud RDS: cpu 4 core, memory 600mb,

Application is running in docker in the ECS.My request data is that :

hosp_id=0&qualified=2&page_index=1&page_size=10&userId=67&sign=61s3f0850331b4deca45567d37319be2

the True response Data is a json string about 7517 bytes.

What sort of data type should I use to communicate with my server?

The chat application allows you to message individual contacts, it works by using a string which looks like this:

"INSTRUCTION=message&CLIENT_FROM=Archie&CLIENT_TO=Friend&MESSAGE=Hello there friend!I understand that you can use SSL sockets, however for the school project using my own way of encrypting the data gives me "more marks" as I can talk about encryption.

Logical operators with possible undefined value in typescript

However if I replace {showDescription && with {isFeatureBlock && description && inline it works perfectly.The Code

isFeatureBlock is a boolean, description is optional string

const showDescription = isFeatureBlock && description

{showDescription && (
<BlockDescription>
{description}
</BlockDescription>
)}


The Error


'Argument of type 'string | undefined' is not assignable to parameter of type 'string'.

Apache rewrite replace variable

I making frendly url for some application, and it works fine with this cond:

RewriteEngine On
RewriteRule ^/shop/([a-z]*)/([a-záéíóúüñç]*)-([a-záéíóúüñç]*)$ /carga.car=$3&model=$2&type=buy&lang=$1&other=$4 [QSA]


after that url loks like that:

Finding eigenvalues of an 'almost-tridiagonal' circulant matrix

Consider the $2N\times 2N$ matrix

$$A=\begin{pmatrix} a &1 &0&0&0&\ldots&0&1 \\1 &-a&1 & 0 &0 & \ldots & 0&0
\\0 &1&a&1&0 &\cdots &0&0 \\ 0&0&1&-a &1 & \ldots &0&0
\\& & & \cdots \\ 1&0 &0&0&0&\ldots &1&-a\end{pmatrix}$$

Hopefully the structure is clear, but if not I can clarify further.There is a lot of literature exclusively on eigenvalues of tridiagonal matrices and circulant matrices, however $A$ is neither exactly circulant nor is it exactly tridaigonal.

A question about $O(3,1)$

Recall that $O(3,1)$ is the collection of matrices $A\in M_4(\mathbb R)$ such that
$$A\begin{pmatrix}1 &&&\\&1&&\\&&1&\\&&&-1\end{pmatrix}A^T=\begin{pmatrix}1 &&&\\&1&&\\&&1&\\&&&-1\end{pmatrix}.Can we find a $Q\in O(3,1)$ such that
$$Q\psi Q^{-1}=\begin{pmatrix} 0&a&&\\-a&0&&\\&&0&b\\&&b&0\end{pmatrix}$$
for some $a,b\in \mathbb R$?

Mean of a vector

Then $$\mu_n\to(2,2,2,2,2,102,102,102,102,102).The exact rate of convergence will be determined by the second-largest singular value of the matrix
$$M =
\begin{bmatrix}
\tfrac13 & \tfrac13 & \tfrac13 & & & \\
\tfrac13 & \tfrac13 & \tfrac13 & & & \\
\tfrac13 & \tfrac13 & \tfrac13 & & & \\
& & & 1 & & \\
& & & & 1 & \\
& & & & & \ddots
\end{bmatrix}
\begin{bmatrix}
1 & & & & & \\
& \tfrac13 & \tfrac13 & \tfrac13 & & \\
& \tfrac13 & \tfrac13 & \tfrac13 & & \\
& \tfrac13 & \tfrac13 & \tfrac13 & & \\
& & & & 1 & \\
& & & & & \ddots
\end{bmatrix}
\begin{bmatrix}
1 & & & & & \\
& 1 & & & & \\
& & \tfrac13 & \tfrac13 & \tfrac13 & \\
& & \tfrac13 & \tfrac13 & \tfrac13 & \\
& & \tfrac13 & \tfrac13 & \tfrac13 & \\
& & & & & \ddots
\end{bmatrix}
\cdots$$
but I don't know how to compute that.

Eigenvalues of permutations of a real matrix: can they all be real?

In rank 4 and 5, a small amount of trial and error yields $M = \pmatrix{1 & T^2 & T^3 & T^3 \\ 0 & 1 & T^2 & T^3 \\ 0 & 0 & 1 & T^2 \\ 0 & 0 & 0 & 1}$ and $M = \pmatrix{1 & T^3 & T^5 & T^6 & T^3 \\ 0 & 1 & T^3 & T^5 & T^6 \\ 0 & 0 & 1 & T^3 & T^5 \\ 0 & 0 & 0 & 1 & T^3 \\ 0 & 0 & 0 & 0 & 1 }$.In rank 6, we have $M = \pmatrix{1 & T^{13} & T^{19} & T^{25} & T^{31} & T^{25} \\ 0 & 1 & T^7 & T^{25} & T^{27} & T^{31} \\ 0 & 0 & 1 & T^{21} & T^{25} & T^{25} \\ 0 & 0 & 0 & 1 & T^7 & T^{19} \\ 0 & 0 & 0 & 0 & 1 & T^{13} \\ 0 & 0 & 0 & 0 & 0 & 1 }$.
