javascript – problem validation form with js to send by post php

I have this form:

If the field is not complete Lastname 1 sends you the toastr well, but when it's complete it does not save it when I call php file. The file.php it works because I've tried it with other things, but now that I've validated it with js no longer llo saves when the field surname_1 is filled.

Installation problem MySQL Server 8.0.16 in Win 32 bits

My question is the following. I'm trying to install MySQL server 8.0.16 on a 32-bit machine and I'm unable.
The mysql installer community indicates this: "Windows (x86, 64-bit), ZIP Archive 8.0.16" after hours of desperation I think I understand that it only means that it installs you on a 64-bit machine but in the Program Files folder (x86)

I do not know if someone can clarify this doubt or if you know any solution to install this version in x32

My tests have been:
 – Installation of virtual machine w7 x86
 – Installation in pc of w7 x86
 – Installation in virtual machine w10 x86
 – Use the zip package of MySQL Installer and run mysql.exe (which already indicates that it is not valid for the selected platform)

The evidence is clear but I would like someone to confirm me.
Greetings and thank you,

angular7: problem of Angular 7 with the listening event in the main component

I am new at angular and I have problems receiving events on the main component. I know that this problem has been discussed above, but somehow none of the tips or tutorials I have read could help me understand what I am doing wrong …

In my childhood component, I do something like this:

import {Component, EventEmitter, OnInit, Output} from & # 39; @ angular / core & # 39;

selector: & # 39; app-test & # 39 ;,
templateUrl: & # 39; ./ test.component.html & # 39 ;,
styleUrls: ['./test.component.css'],
template: ` `
The TestComponent export class implements OnInit {

@Output () onTestEvent = new EventEmitter()
public text: string = "blah";

builder () {}

ngOnInit () {

nameChanged () {
console.log (& # 39; Sending test event! & # 39;);
this.onTestEvent.emit (this.text)

In my main component html file I do something like this:

    (onTestEvent) = "handleTestEvent ($ event)"

In my main component file ts I do something like this:

        handleTestEvent (text: string) {
console.log (& # 39; handling test event .... & # 39;);

I can see that the nameChanged function is called when I press the button, but I do not receive the event in the main component for some reason that surpasses me …

SAS Visual Analytics 8.2 line graph problem

I'm having trouble making a simple line chart in SAS Visual Analytics version 8.2. I just want to plot the aggregate average value of the observations on the y-axis versus the observation times (day number) on the x-axis.

Otherwise, the line chart works well, but SAS VA wants to locate my x-axis labels evenly, although my values ​​of x are observation times spaced unevenly. I could not find the option to change the x axis to the continuous type axis instead of the categorical one.

I also tried the graph of numerical series and changed the data type of the variable x to a measure. This also did not work: now, in some way, the values ​​of my y-axis are not added as in the line graph, but rather every time the x-axis shows a group of observations on the y-axis.

How can I make a line graph with the average value of the observations at a time on a continuous x-axis?

Thank you!

Problem with Multidimensional Array in Python

Basically my algorithm imports all the photos I have inside a directory (dataset_train), saving these photos in vector X and the name of the folder in which it was in vector Y.

import cv2
import numpy the np

x = []
y = []

is root, dirs, files in os.walk ("dataset_train"):
path = root.split (os.sep)
for files in files:
image_name = root + & # 39; / & # 39; + file
image = cv2.imread (image_name, 0)
x.append (image)
y.append (path[1])

print (& # 39; read training images: & # 39 ;, len (x))

(x_train, y_train) = (np.asarray (x), y)

printing (x_train.shape)
printing (x_train[0].shape)


Images for the read training: 11957


(250, 250)

I'm using the MNIST CNN algorithm as a basis, in which it has 60000 images, 28×28 pixels. In this algorithm when I use so () in the training vector he returns (60000, 28, 28). But when I do it in me he comes back only (11957)I need you to come back (11957, 250, 250). My dataset are 250×250 pixel photos.

Can someone help me with that, please? I'm a newbie in Python 🙁

Problem with mod_deflate – compressing the executable file

When trying to download the file with the .EXE extension on the site, the files come as .GZ Ambient
Centos 7 64
Apache 2.4.6

However, by changing the file in /etc/httpd/conf/httpd.conf, I tried using each of these methods below (I did not restart Apache and removed the browser cache on every attempt):

one: SetEnvIfNoCase Request_URI .exe $ no-gzip dont-vary

two: SetEnv no-gzip 1

3: SetEnv mod_deflate disabled

4: SetEnv no-gzip disabled

5: In the file /etc/httpd/conf.modules.d/00-base.conf I commented: LoadModule deflate_module modules /

6: I tried to delete the file, but it did not work. /usr/lib64/httpd/modules/

All help is welcome.
I have researched a lot, I relied on several tests with similar solutions, but to no avail.
I do not know what to try anymore.

Own value problem – Mathematica Stack Exchange

my question is about solving a problem of own value of the Helmholtz equation using the sync approach [Del]^ 2E + V (x) = [Lambda] E and V (x) = X ^ 2/2

I have a problem calculating the eigenvalues ​​of this system because the eigenvalues ​​if you know that this system is [Lambda]= {1/2, 3/2, 5/2}

My code is:

Nn = 8
h = [Pi]/ Sqrt[2 Nn]
   h1 = h

exactdelta2 = h1 ^ 2 D[S1[[Phi]one[x], j, h1], {[Phi]one[x], two}]ex5 = exactdelta2 /. x -> [Psi]one[x] /. [Phi]one[[[[[Psi]one[x_]]:> x /.
x -> k h1

ex6 = ex5 /. S1 -> Function[{xkh}Sinc[[{xkh}Sinc[[{xkh}Sinc[[{xkh}Sinc[[Pi] (x - k h) / h]]nabla = Table[ex6, {k, -Nn, Nn}, {j, -Nn, Nn}] /.
Indeterminate:> Limit[ex6, k -> j] 

   vx[x_] = x ^ 2/2 /. x -> k h

vx1 = Table[vx[vx[vx[vx[x], {k, -Nn, Nn}]vxmat = DiagonalMatrix[vx1]

   A = nabla + vxmat // N

lamda = eigenvalues[A]

The main problem with MyBB | Promotion Forum

I like the MyBB software, but the problem is the login errors, when the theme is not compatible with the latest update. It's so irritating, that I move to phpBB for some of my free forum software projects.

Anyway, this is unfortunate, since I like MyBB the most in most cases.
