How do i create asp.net code for Password Strength? : I am looking to implement a password strength feature for my textbox in my asp.net website.
Currently, my aspx code looks like this :
<span id="password_strength"></span>
<script type="text/javascript">
function CheckPasswordStrength(password) {
var password_strength = document.getElementById("password_strength");
//if textBox is empty
if(password.length==0){
password_strength.innerHTML = "";
return;
}
//Regular Expressions
var regex = new Array();
regex.push("[A-Z]"); //For Uppercase Alphabet
regex.push("[a-z]"); //For Lowercase Alphabet
regex.push("[0-9]"); //For Numeric Digits
regex.push("[$@$!%*#?&]"); //For Special Characters
var passed = 0;
//Validation for each Regular Expression
for (var i = 0; i < regex.length; i++) {
if(new RegExp (regex[i]).test(password){
passed++;
}
}
//Validation for Length of Password
if(passed > 2 && password.length > 8){
passed++;
}
//Display of Status
var color = "";
var passwordStrength = "";
switch(passed){
case 0:

Can't get claims from JWT token with ASP.NET Core : <p>I'm trying to do a really simple implementation of JWT bearer authentication with ASP.NET Core. I return a response from a controller a bit like this:</p>

identity.AddClaim(new Claim(ClaimTypes.Name, applicationUser.UserName));
var jwt = new JwtSecurityToken(
_jwtOptions.Issuer,
_jwtOptions.Audience,
identity.Claims,
_jwtOptions.NotBefore,
_jwtOptions.Expiration,
_jwtOptions.SigningCredentials);
var encodedJwt = new JwtSecurityTokenHandler().WriteToken(jwt);
return new JObject(
new JProperty("access_token", encodedJwt),
new JProperty("token_type", "bearer"),
new JProperty("expires_in", (int)_jwtOptions.ValidFor.TotalSeconds),
new JProperty(".issued", DateTimeOffset.UtcNow.ToString())
);
</code></pre>
<p>I have Jwt middleware for incoming requests:</p>
<pre><code>app.UseJwtBearerAuthentication(new JwtBearerOptions
{
AutomaticAuthenticate = true,
AutomaticChallenge = true,
TokenValidationParameters = tokenValidationParameters
});
</code></pre>
<p>This seems to work to protect resources with the authorize attribute, but the claims never show up.</p>

Output:
Date: 2017-12-1 00:00:00:00

Add weights to .pb file exported by TensorFlow : <p>My project uses Python to train a MLP on TensorFlow and then I export the graph and the weights in that way:</p>
<pre><code>tf.train.write_graph(sess.graph_def, "./", "inp.txt", True)
saver.save(sess, 'variables/model.ckpt', global_step=1)
</code></pre>
<p>Now, although it is fine to use both files to import it back to Python it seems impossible to use it for Android or C++ since it cannot inport the checkpoint .ckpt.</p>
<p>Right now, I'm using the script <code>freeze_graph.py</code> provided by google to join both files into one by doing:</p>
<pre><code>bazel-bin/tensorflow/python/tools/freeze_graph --input_graph=inp.txt --input_checkpoint=variables/model.ckpt-1 --output_graph=newoutput.pb --output_node_names=output
</code></pre>
<p>My question is, is there a way to use another function instead of <code>tf.train.write_graph</code> to export it with the weights included?</p>

SQL noob - Car dealership stock orders list : This may have already been asked before, but I couldn't find much. Please redirect me if so.
I work for a big car dealership in Switzerland. We receive dayly a List of cars in our carparks located all around the country.
This list serves us to find which car our clients are looking for, so that we can propose them an offer.
The list is huge and difficult to work with.
For instance all optional and modelversions are written all in one cell....
So I had the idea to build a database, with a research form and a report in Ms Access so that we just need to load this list in an excel sheet, run a formatting macro in order to have a proper list to work with, then feed it to the database through table connection. This will definitely save us a lot of time
So, at the end of the formatting macro my list look kinda like this:[formatted car list][1]
Since the same Optionals on different cars have different prices I need to have my Data to look like this:[target table format][2], so that in my report I can do a table join query and have a list of the car's optionals with their prices.
Is there a way to do a "Table Normalisation" in MS Access?
Ty all for the answers in advance!

Please explain DEFER's behaivour in golang : <p>As I know, defer is usually used to close or free resources.
And using <code>defer FUNC ()</code> inside the block (function) of the code ensures that <code>FUNC ()</code> will call in case of any return from this block(function) or panic in this block (function).</p>
<p>So - how to explain <code>defer</code> behavior in this code: (<a href="https://play.golang.org/p/FPA0wrRyw1f" rel="nofollow noreferrer">Example</a>):</p>
<pre><code>package main
import (
"fmt"
"errors"
)
func test() error {
err := errors.New("some error")
return err
}
func main() {
if err := test(); err!=nil {
fmt.Println("ERROR EXIT")
return
}
defer fmt.Println("DEFER EXIT")
fmt.Println("NORMAL EXIT")
}
</code></pre>
<p>I expected to see this:</p>
<pre><code>ERROR EXIT
DEFER EXIT
</code></pre>
<p>But got it:</p>
<pre><code>ERROR EXIT
</code></pre>
<p>Where am I wrong?</p>

php divide with 'easy' numbers : <p>I'm working on a program in PHP that lets you train for making calculations without a calculator. The problem I run into is that when generating random numbers for the sums you can get awkward numbers like 4 divided by 7. Is there an easy way to generate easy sums like 9 divided by 3?</p>

Should Sequelize migrations update model files? : <p>Are Sequelize migrations supposed to keep your model files in line with your database?</p>
<p>I used the sequelize cli to bootstrap a simple project and create a model <code>node_modules/.bin/sequelize model:generate --name User --attributes email:string</code>. I migrated this with no issue. </p>
<p>Then I created the following migration file to add a notNull constraint to the user email attribute.</p>
<p><strong>updateEmail migration</strong></p>
<pre><code>const models = require("../models")
module.exports = {
up: (queryInterface, Sequelize) => {
return queryInterface.changeColumn(models.User.tableName, 'email',{
type: Sequelize.STRING,
allowNull: false,
});
},
down: (queryInterface, Sequelize) => {
return queryInterface.changeColumn(models.User.tableName, 'email',{
type: Sequelize.STRING,
});
},
};
</code></pre>
<p>The database schema updated to add the constraint but the model file did not. Is there a way to automatically update the model files as you make migrations?</p>

Adding "Open Anaconda Prompt here" to context menu (Windows) : <p>I'd like to add an option on my context menu (Windows 7 and 10) to open an Anaconda Prompt into the file location when I right-click the folder, but I can't figure out the right registry key.</p>
<p>Here's what I know how to do: </p>
<ul>
<li>Add an item to the context menu that opens a normal command window at the folder location </li>
<li>Open an Anaconda prompt from cmd (run their "activate.bat" file) </li>
</ul>
<p>What I can't figure out is how to combine these steps into a single registry key so I can open an Anaconda Prompt and then cd in that prompt to the current folder. But maybe I'm approaching this the wrong way.</p>

TensorFlow - regularization with L2 loss, how to apply to all weights, not just last one? : <p>I am playing with a ANN which is part of Udacity DeepLearning course.</p>
<p>I have an assignment which involves introducing generalization to the network with one hidden ReLU layer using L2 loss. I wonder how to properly introduce it so that ALL weights are penalized, not only weights of the output layer.</p>
<p>Code for network <em>without</em> generalization is at the bottom of the post (code to actually run the training is out of the scope of the question).</p>
<p>Obvious way of introducing the L2 is to replace the loss calculation with something like this (if beta is 0.01):</p>
<pre><code>loss = tf.reduce_mean( tf.nn.softmax_cross_entropy_with_logits(out_layer, tf_train_labels) + 0.01*tf.nn.l2_loss(out_weights))
</code></pre>
<p>But in such case it will take into account values of output layer's weights. I am not sure, how do we properly penalize the weights which come INTO the hidden ReLU layer. Is it needed at all or introducing penalization of output layer will somehow keep the hidden weights in check also?</p>

How to call REST from jenkins workflow : <p>I wonder how to call REST API from a (groovy) Jenkins workflow script. I can execute "sh 'curl -X POST ...'" - it works, but building the request as a curl command is cumbersome and processing the response gets complicated. I'd prefer a native Groovy HTTP Client to program in groovy - which one should I start with? As the script is run in Jenkins, there is the step of copying all needed dependency jars to the groovy installation on Jenkins, so something light-weight would be appreciated.</p>
