## cryptography – Diffie-Hellman with non-main module

When using the Diffie-Hellman key exchange, it is said that it is important to use a secure priming. However, if a non-main module with a sufficient length of bits is generated, is there an attack that can be used to recover the shared secret of the public communication (g, g ^ a, g ^ b, module) or to decrypt a message? encryption?

## linux – Error flooding is related to the alx module

My Linux box is flooded with the following error at a very high rate that makes journald have high CPU performance, which causes the CPU fan to start up. Interestingly, the network still works. Internet is not much help, we only find some irrelevant articles that makes at least several cores. Any ideas about what is happening?

## Powershell module, Posh-SSH: How is the sequence reading supposed to work in Posh-SSH?

I am trying to understand how the flow reading is supposed to work in Posh-SSH in order to arm a "wait action" function so that the script continues only after the remote command is completed.

The intent of the code shown below, when put together, is to initiate a "yum update" on the remote system (Linux, CentOS 7), then monitor the sequence to determine when the remote command has been completed and then move on to the next line of the script. It works "sometimes", but not always.

This code successfully configures a new SSH connection and defines a flow:

``````\$ hostIP = "Remote_Linux_Server_IP"
\$ centosCreds = "My_Credential_Object"
\$ pemFile = "My_Pem_File"
New-SSHSession-Computer Name \$ hostIP-Port 22-Credit \$ centosCreds -KeyFile \$ pemFile -ConnectionTimeout 120 -OperationTimeout 120 -AcceptKey
\$ stream = New-SSHShellStream -Index 0
``````

The execution of a remote command through the new sequence is quite easy:

``````Invoke-SSHStreamShellCommand -ShellStream \$ stream -Command "yum update"
``````

Executing the following while executing the Invoke-SSHStreamShellCommand (yum update) command returns a fragment of the remote command output as expected:

``````\$ stream.Read ()
``````

However, once the "yum update" is complete, the reading of the sequence returns only a blank value. The information I could find online indicates that reading the sequence should return the string of the command prompt of the remote system, but this does not seem to be the case.

Because the value returned by the read after the command has completed is blank, the "wait action" cycle that I am trying to assemble does not work consistently:

``````\$ promptString = "Regex_Matching_Remote_System_Command_Prompt"
\$ streamOut = \$ stream.Read ()
while (\$ streamOut - I do not like "\$ promptString") {
Home-dream -s 1
\$ streamOut = \$ stream.Read ()
}
``````

I'm not sure what I'm missing here: the documentation is limited and I have not been able to find many other examples of continuous Posh-SSH readings that match the behavior I'm seeing.

Any guidance or suggestion is appreciated.

Thank you.

## theme – Pass the custom module variable to the twig template

How can I pass a variable from my custom module to a twig field template?

My field template is "field – node – field – webform – show – visit.html.twig"

and my module is called "custommodule"

I tried this function according to the documentation but apparently I did not understand something correctly:

``````        logintosubmit_preprocess_field_node_field_webform_parliament_visit (array & \$ variables) {function
\$ VARIABLE_NAME = & # 39; my_variable & # 39 ;;
\$ variables['varname'] = \$ VARIABLE_NAME;
}

## javascript – Division without using division, multiplication or module operators

Homework

Implement the division of two positive integers without using the
Division, multiplication or module operators. Returns the quotient as
An integer, ignoring the rest.

My solution

``````division of const = (dividend, divisor) => {
leave remainder = null;
leave quotient = 1;
sign of const = ((dividend> 0 and divisor <0) ||
(dividend < 0 && divisor > 0))?
~ 1: 1;

leave tempdividend = Math.abs (dividend);
let tempdivisor = Math.abs (divisor);

if (tempdivisor === tempdividend) {
rest = 0;
return Math.abs (sign);
} else if (tempdividend <tempdivisor) {
remainder = dividend <0?
sign <0? ~ tempdividend: tempdividend:
tempdividendo
returns 0;
}
while (tempdivisor << 1 <= tempdividend) {
tempdivisor = tempdivisor << 1;
quotient = quotient << 1;
}

quotient = dividend <0?
(sign <0? quotient: quotient) + division (~ (tempdividend-tempdivisor), divisor):
(sign <0? quotient: quotient) + division (tempdividend-tempdivisor, divisor);
return ratio;
}
``````

## module – Magento 1.9 adds custom field to multiple templates

I have a custom field that I would like to add to all areas in the admin panel where you can change the quantity of a product. I currently have the impression that I have to rewrite each template individually.

For example, to add the field to the inventory tab in the editing product, I made a rewrite of the template as follows:

Config.xml

``````

``````

Inventory.php

``````getAttribute (Mage_Catalog_Model_Product :: ENTITY, & # 39; stock_reason & # 39;);

if (\$ attribute-> usesSource ()) {
\$ options = \$ attribute-> getSource () -> getAllOptions (true);
}

returns \$ options;
}
public function __build ()
{
father :: __build ();
\$ this-> setTemplate (& # 39; vish / catalog / product / tab / inventory.phtml & # 39;);
}
}
``````

I think that, consequently, I would do the same for the attribute update action. This seems redundant and repetitive, and did I want to ask myself if I am doing this correctly? Or does the magento have a better way?

## magento2 – Magento 2: How to pass an existing module in the provider to the application folder?

I want to pass a module from the provider folder called "payment module" to the application folder. But every time I try to register this module in the application, an error appears that says that the module "already exists in the provider's folder". How can I register this module in the application folder? Can anybody help me please?

## Arithmetic geometry – Tower of module spaces in Scholze's theory.

My question is related to another one that I read here in Overflow. I'm reading Scholze's articles on moduli modules. $$p$$– Divisible groups and elliptical curves, and I'm very interested in the formal geometry involved there. In fact, I noticed that there is an article by Andreatta, Iovita and Pilloni, entitled Le halo spectral, which seems to deal with formal integral models of the Scholze towers.

First, if I understand Scholze well, speaking of elliptical curves, there is a perfect space. $$mathcal {X} _ { infty} ( epsilon)$$ What gives the "limit tilda" of modular curves. $$mathcal {X} _ { Gamma (p ^ n)} ( epsilon)$$ where each $$mathcal {X} _ { Gamma (p ^ n)} ( epsilon)$$ Describe the open neighborhoods of the ordinary place of $$Gamma_1 (N)$$ Modular curve, where the universal elliptical curve that comes from the recoil is not too supersingular. In fact, the construction of this object is done by calculating the generic fiber addition of the formal scheme. $$mathfrak {X} _ { infty} ( epsilon)$$ What is the real limit (in the category of formal schemes) of the integral models of $$mathcal {X} _ { Gamma_ (p ^ n)} ( epsilon)$$ where the maps in the reverse system are given by a survey of mod $$p$$-Frobenius.

A very similar construction is done in the chapter. $$6$$ of Andreatta, Iovita and the role of Pilloni, where they build the anti-canonical integral tower. $$mathfrak {X} _ { infty}$$ in exactly the same way, but working on a base that is a proper explosion of an integral model of Coleman's space weight. Now, I wonder if it is possible or not to interpret these spaces of "infinite" levels as spaces of elliptic curve modules plus a new type of level structure. Somewhere in Scholze's article it is mentioned that a point of $$mathcal {X} _ { infty}$$ finished $$text {Spa} (C, mathcal {O} _C)$$, where $$C$$ It is a complete algebraically closed extension of $$mathbb {Q} _p$$ corresponds to an elliptical curve on $$C$$ With a trivialization of your Tate module. Now, why is this true? It is not mentioned in Scholze and I can not prove it. In addition, a similar description is maintained for different types of points, p. $$text {Spa} (R, R ^ +)$$ with $$R$$ a perfect $$mathbb {Q} _p$$-algebra? Also, does the same interpretation hold for its formal integral model? And what about the tower of Andreatta, Iovita and Pilloni? Is it true that you parametrize elliptic curves with $$p$$Divisible groups that play the role of the canonical subgroup? The point is essentially, does this object back off a universal elliptical curve? What level level does a similar elliptical curve have?
