XSLT output JSON instead of XML | <p>I have a XSLT that works the way I want when it outputs XML, however I would like to change the XSLT it to output JSON instead. The problem appears to me with the inner most for-each loop, but I'm not sure. If there is way to make this more efficient I'm also interested in your suggestions. </p>
<p>Sample input XML</p>

<p>Good point, so the XML version groups all the attributes for the same table together; Given the sample above the XML output is as follows</p>
<pre><code><root xmlns:xs="http://www.w3.org/2001/XMLSchema">
<Table TableName="HH_ENODEB" Stamp="2016-08-25T04:30:00-07:00" measObjLdn="LTHBC0126858/GTPU:Board Type=MPT, Cabinet No.=0, Subrack No.=1, Slot No.=7" Element_Type="ENODEB" Key1="LTHBC0126858" H1526727075="0" H1526727076="0" H1526727077="0"/>
</code></pre>
<p></p>
<p>JSON example output is not a JSON version of the XML version which I expected.</p>
<pre><code>{"root":{"Table":[{"TableName":"HH_ENODEB","Stamp":"2016-08-25T04:30:00-07:00","measObjLdn":"LTHBC0126858/GTPU:Board Type=MPT, Cabinet No.=0, Subrack No.=1, Slot No.=7","Element_Type":"ENODEB","Key1":"LTHBC0126858","H1526727075":"0""Stamp":"2016-08-25T04:30:00-07:00","measObjLdn":"LTHBC0126858/GTPU:Board Type=MPT, Cabinet No.=0, Subrack No.=1, Slot No.=7","Element_Type":"ENODEB","Key1":"LTHBC0126858","H1526727076":"0""Stamp":"2016-08-25T04:30:00-07:00","measObjLdn":"LTHBC0126858/GTPU:Board Type=MPT, Cabinet No.=0, Subrack No.=1, Slot No.=7","Element_Type":"ENODEB","Key1":"LTHBC0126858","H1526727077":"0"}}

Error in is.data.frame(x) : object '' not found , how could I fix this? | <p>I'm trying to run correlations on R.</p>
<p>This is my code so far:</p>
<pre><code>library("foreign")
mydata<-read.csv(" ",header=FALSE)
options(max.print=1000000)
attach(mydata)
cor(as.numeric(agree_election),as.numeric(agree_party))
</code></pre>
<p>Then it gives me the error that object "agree_election" is not an object.</p>
<p>However, agree_election is just one of the headers of my columns for my excel spreadsheet.How do I fix this?</p> | 0 |
How do I exclude a specific URL in a filter in Spring? | <p>I have a basic application filter config that looks like this:</p>
<pre><code>@Configuration
public class ApplicationFilterConfig {
/**
* Check if user is logged in
*/
@Bean
public FilterRegistrationBean applicationFilterRegistration() {
// created a collections that need logins to be validated.
ArrayList<String> urlPatterns = new ArrayList<String>();
urlPatterns.add("/home");
urlPatterns.add("/about");
urlPatterns.add("/contact");
// ...
LoginFilter loginFilter = new LoginFilter();
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(loginFilter);
registration.setUrlPatterns(urlPatterns);
registration.setOrder(1);
return registration;
}
}
</code></pre>
<p>However, the list <code>urlPatterns</code> grows to be very long, even when using the star annotation (e.g. <code>/employees/*</code>). The main reason why I don't just use <code>/*</code> is because I don't want to require login validation for my login page. If I did, it'd create an infinite loop of redirects. </p>
<p>Does the <code>FilterRegistrationBean</code> class allow you to apply a filter to all URL patterns <em>except</em> certain patterns? </p>
<p>I could put everything except the login page in a directory and set my URL pattern to be <code>/subdirectory/*</code> but that adds an unnecessary level of depth to every file in my webapp. </p> | 0 |

Angular 2 REST request HTTP status code 401 changes to 0 | <p>I'm developing an Angular2 application. It seems when my access-token expires the 401 HTTP Status code gets changed to a value of 0 in the Response object. I'm receiving 401 Unauthorized yet the ERROR Response object has a status of 0. This is preventing me from trapping a 401 error and attempting to refresh the token. What's causing the 401 HTTP status code to be changed into HTTP status code of 0?</p>
<p>Here's screenshot from Firefox's console:</p>
<p><a href="https://i.stack.imgur.com/cgGQv.png" rel="noreferrer"><img src="https://i.stack.imgur.com/cgGQv.png" alt="enter image description here"></a></p>
<p>Here's my code:</p>
<pre><code>get(url: string, options?: RequestOptionsArgs): Observable<any>
{
//console.log('GET REQUEST...', url);
return super.get(url, options)
.catch((err: Response): any =>
{
console.log('************* ERROR Response', err);
if (err.status === 400 || err.status === 422)
{
return Observable.throw(err);
}
//NOT AUTHENTICATED
else if (err.status === 401)
{
this.authConfig.DeleteToken();
return Observable.throw(err);
}
else
{
// this.errorService.notifyError(err);
// return Observable.empty();
return Observable.throw(err);
}
})
// .retryWhen(error => error.delay(500))
// .timeout(2000, new Error('delay exceeded'))
.finally(() =>
{
//console.log('After the request...');
});
}

<p>This code resides in a custom http service that extends Angular2's HTTP so I can intercept errors in a single location.</p>
<p>In Google Chrome, I get this error message:</p>
<p>XMLHttpRequest cannot load <a href="https://api.cloudcms.com/repositories/XXXXXXXXXXXXXXXX/branches/XXXXXXXXXXXXXXXX/nodesXXXXXXXXXXXXXXXX" rel="noreferrer">https://api.cloudcms.com/repositories/XXXXXXXXXXXXXXXX/branches/XXXXXXXXXXXXXXXX/nodesXXXXXXXXXXXXXXXX</a>. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '<a href="http://screwtopmedia.local.solutiaconsulting.com" rel="noreferrer">http://screwtopmedia.local.solutiaconsulting.com</a>' is therefore not allowed access. The response had HTTP status code 401.</p>
<p>This is confusing because I am including 'Access-Control-Allow-Origin' header in request.</p>
<p>Here's a picture of results received in Google Chrome:</p>
<p><a href="https://i.stack.imgur.com/B4sb7.png" rel="noreferrer"><img src="https://i.stack.imgur.com/B4sb7.png" alt="enter image description here"></a></p>
<p>I've tried accessing 'WWW-Authenticate' Response Header as a means to trap for 401. However, the following code returns a NULL:</p>
<pre><code>err.headers.get("WWW-Authenticate")
</code></pre>
<p>It's puzzling that I'm getting a CORS issue because I'm not getting any CORS errors when a valid access token is provided.</p>
<p>How do I trap for 401 HTTP status code? Why is 401 HTTP status code being changed to 0?</p>
<p>Thanks for your help.</p> | 0 |

R Tidytext and unnest_tokens error | <p>Very new to R and have started to use the tidytext package.</p>
<p>I'm trying to use arguments to feed into the <code>unnest_tokens</code> function so I can do multiple column analysis. So instead of this</p>
<pre><code>library(janeaustenr)
library(tidytext)
library(dplyr)
library(stringr)
original_books <- austen_books() %>%
group_by(book) %>%
mutate(linenumber = row_number(),
chapter = cumsum(str_detect(text, regex("^chapter [\\divxlc]",
ignore_case = TRUE)))) %>%
ungroup()
original_books
tidy_books <- original_books %>%
unnest_tokens(word, text)

<p>The last line of code would be:</p>
<pre><code>output<- 'word'
input<- 'text'
tidy_books <- original_books %>%
unnest_tokens(output, input)

Input must be a character vector of any length or a list of character
vectors, each of which has a length of 1.</p>

Can you use @ViewChild() or similar with a router-outlet? How if so? | <p>I repeatedly run into a situation where I'd like to access a child component existing on the other side of a router outlet rather than a selector:</p>
<pre><code>Like:
<router-outlet></router-outlet>
NOT:
<selector-name></selector-name>
</code></pre>
<p>This conflicts with the ViewChild functionality as I know it, yet it seems like my component should be able to see and interact with what's inside that router-outlet just as easily as with what's inside a selector-tag.</p>
<p>For instance I tried this:</p>
<pre><code>export class RequestItemCatsComp {
@ViewChild('child') child: RequestItemsComp;
***etc...***
ngAfterViewInit() {
if (this.child) // Always child is undefined
this.groupId = this.child.groupId;
}
}
</code></pre>
<p>But naturally, <strong>child is undefined</strong> because this is the wrong way. Is there a right way?</p>
<p>I'm trying to use a service to share the data but then run into another problem "expression has changed after it was checked" which I'm hoping to remedy without a hack or enabling prod mode.</p> | 0 |
possible to whitelist ip for inbound communication to an ec2 instance behind an aws load balancer? | <p>I have a single ec2 instance running a website behind an elastic load balancer in aws. Mainly because I want to use Amazon's new and free ssl for https.</p>
<p>my challenge is, I need to whitelist my IP address in the security groups so that I am the only person that can see this website (and I can selectively add people as needed). </p>
<p>I've successfully whitelisted my IP address without a load balancer. my challenge is white listing my IP address with the load balancer proxy between my IP address and my ec2 instance.</p>
<p>it appears as if my ec2 instance will not register with the load balancer because the security group for my ec2 does not allow incoming traffic from any IP address except for my own.</p>
<p>I am looking for a way for my load balancer to be able to health check my ec2, yet only allow specific whitelisted ips actually see the website.</p> | 0 |

Importing spark.implicits._ in scala | <p>I am trying to import spark.implicits._
Apparently, this is an object inside a class in scala.
when i import it in a method like so:</p>
<pre><code>def f() = {
val spark = SparkSession()....
import spark.implicits._
}
</code></pre>
<p>It works fine, however i am writing a test class and i want to make this import available for all tests
I have tried:</p>
<pre><code>class SomeSpec extends FlatSpec with BeforeAndAfter {
var spark:SparkSession = _
//This won't compile
import spark.implicits._
before {
spark = SparkSession()....
//This won't either
import spark.implicits._
}
"a test" should "run" in {
//Even this won't compile (although it already looks bad here)
import spark.implicits._
//This was the only way i could make it work
val spark = this.spark
import spark.implicits._
}
}
</code></pre>
<p>Not only does this look bad, i don't want to do it for every test

Merging many arrays from Promise.all | <p>When <code>Promise.all</code> completes it returns an array of arrays that contain data. In my case the arrays are just numbers:</p>
<pre><code>[
[ 1, 4, 9, 9 ],
[ 4, 4, 9, 1 ],
[ 6, 6, 9, 1 ]
]
</code></pre>
<p>The array can be any size.</p>
<p>Currently I'm doing this:</p>
<pre><code>let nums = []
data.map(function(_nums) {
_nums.map(function(num) {
nums.push(num)
})
})
</code></pre>
<p>Is there an alternative way of doing this? Does <code>lodash</code> have any functions that are able to do this?</p> | 0 |
How to hide bar button item | <p>My screen flow is as follow</p>
<p>Login -> Registration -> CarDetails </p>
<p>All 3 above screens are in navigation-controller, but users are not allowed to go back from Car-Details to Registration. To achieve it, I've</p>
<pre><code>override func viewWillAppear(animated: Bool)
{
self.navigationItem.setHidesBackButton(true, animated:true);
}
</code></pre>
<p>in CarDetails view controller. So it hides the back button which automatically gets created if controller is in navigation-controller.</p>
<p>So far it is good.</p>
<p>After providing all detail user lands on Home Screen where I've slide out menu. From menu user can goto to CarDetail Screen as well (to update). That time instead of backButton I need slide-out menu button as left bar button. So I've created it using storyboard. </p>
<p>The problem is that it is getting displayed after Registration view as well. I need conditional show/hide functionality for it in Car-Details View.</p>
<p>I've hook for it as well, as following</p>
<pre><code>override func viewDidLoad()
{
super.viewDidLoad()
if menuButtonVisibility
{
if self.revealViewController() != nil
{
menuButton.target = self.revealViewController()
menuButton.action = "revealToggle:"
self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
}
}
else
{
}
menuButtonVisibility=true
}
</code></pre>
<p>I only need the line to put in else block.</p>

Mongodb $project: $filter sub-array | <p>There is an items (mongoose) schema that looks like this (simplified to what it matters to the question):</p>
<pre><code>{
brand: {
name: String,
},
title: String,
description: [{ lang: String, text: String }],
shortDescription: [{ lang: String, text: String }],
variants: {
cnt: Number,
attrs: [
{
displayType: String,
displayContent: String,
displayName: [{ lang: String, text: String }],
name: String,
},
],
}
}
</code></pre>
<p>I'm trying to filter the items by language, so I've constructed the following query:</p>
<pre><code>db.items.aggregate([
{ $match: { 'description.lang': 'ca', 'shortDescription.lang': 'ca' } },
{ $project: {
'brand.name': 1,
title: 1,
description: {
'$filter': {
input: '$description',
as: 'description',
cond: { $eq: ['$$description.lang', 'ca'] }
}
},
shortDescription: {
'$filter': {
input: '$shortDescription',
as: 'shortDescription',
cond: { $eq: ['$$shortDescription.lang', 'ca'] }
}
},
'variants.cnt': 1,
'variants.attrs': 1
} }
])
</code></pre>
<p>And it works as expected: it filters <code>description</code> and <code>shortDescription</code> by language. Right now I'm wondering if it could be possible to filter every <code>variants.attrs.$.displayName</code> as well. Is there any way to do it?</p>
<p>I've been trying to <code>$unwind</code> <code>variant.attrs</code> but I get completly lost when trying to <code>$group</code> again and I'm not really sure if this is the best way...</p> | 0 |

How to get the REST response in Groovy? | <p>I have to write a small script within a web app. This web app has it's limitations but is similar to this online console: <a href="https://groovyconsole.appspot.com/" rel="noreferrer">https://groovyconsole.appspot.com/</a> so if it works here, it should work for my problem as well.</p>
<p>I need to parse a JSON response. For simplicity I developed in C# my own web API and when I enter on the browser the link (<a href="http://localhost:3000/Test" rel="noreferrer">http://localhost:3000/Test</a>) it gives this string :</p>
<pre><code>{"Code":1,"Message":"This is just a test"}
</code></pre>
<p>I want to get this string, and parse it afterwards, I guess with JsonSplunker. After hours of research, the most compelling sample would be this:</p>
<pre><code>import groovyx.net.http.RESTClient
def client = new RESTClient( 'http://www.acme.com/' )
def resp = client.get( path : 'products/3322' ) // ACME boomerang
assert resp.status == 200 // HTTP response code; 404 means not found, etc.
println resp.getData()

<p>However it does not recognize <code>import groovyx.net.http.RESTClient</code>. You can try testing it in the groovy web sonsole provided and you will get the error.</p>

pandas group by ALL functionality? | <p>I'm using the <code>pandas groupby+agg</code> functionality to generate nice reports</p>

<p>or:</p>
<pre><code>df.agg(aggs_dict)

df.a.std()
df.b.size()
....

Laravel: How can I change the default Auth Password field name? | <p>I am currently working on my first laravel project and I am facing a problem.</p>
<p>If you have experience with laravel you probably know that by calling <code>php artisan make:auth</code> you will get a predefined mechanism that handles login and registration.</p>
<p>This mechanism is set to understand a couple of commonly used words in order to automate the whole procedure.</p>
<p>The problem that occurs in my case is that I am using oracle db and it won't let me have a table column with the name of <code>password</code> because its a system keyword and it throws errors when trying to insert a user.</p>
<p>So far, I have tried to change my <code>password</code> column to <code>passwd</code> and it worked in my registration form as expected. The User row was successfully inserted and my page was redirected to /home.</p>
<p><a href="https://i.stack.imgur.com/LdZQK.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/LdZQK.png" alt="Register" /></a></p>
<p><a href="https://i.stack.imgur.com/89aTR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/89aTR.png" alt="Success" /></a></p>
<p>But when I try to logout and then relogin, I get this error telling me that my credentials are not correct:</p>
<p><a href="https://i.stack.imgur.com/GEFR8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/GEFR8.png" alt="enter image description here" /></a></p>
<p>As for my code, I have changed my <code>RegisterController.php</code> so that it takes username instead of email</p>
<pre><code>protected function validator(array $data)
{
return Validator::make($data, [
'username' => 'required|max:50|unique:ECON_USERS',
'passwd' => 'required|min:6|confirmed',
]);
}
protected function create(array $data)
{
return User::create([
'username' => $data['username'],
'passwd' => bcrypt($data['passwd'])
]);
}
</code></pre>
<p>The User $fillable</p>
<pre><code>protected $fillable = [
'username', 'passwd'
];
</code></pre>
<p>I am guessing that Auth is trying to authenticate with <code>email</code> and not <code>username</code> or that Auth is searching for <code>password</code> and not <code>passwd</code>.</p> | 0 |
Converting GET request parameter to int ... if it is numeric | <p>lets say i'm showing some data to user , i want user to be able to perform some sort of filtering on a numeric field in the database using a <code>GET</code> form so i have something like this </p>

condition = {}
if( code is not None and int(code) > 0 ):
condition['code'] = int(code)

Convert HH:MM:SS AM/PM string to time | <p>I need to parse times in a character format like "1:36:22 PM".</p>

<pre><code>t <- "1:36:22 PM"
as.POSIXct(t, format = "%H:%M:%S")
# [1] "2016-09-08 01:36:22 BST"
</code></pre>
<p>and this fails:</p>
<pre><code>strptime(t, "%H:%M:%S")
# [1] NA
</code></pre>
<p>Curiously, for reasons I can't understand, dropping the seconds from the input <em>may</em> work:</p>
<pre><code>t <- "1:30:00 PM"
strptime(t, "%I:%M %p")
# [1] NA
t <- "1:30 PM"
strptime(t, "%I:%M %p")
# [1] "2016-09-08 13:30:00 BST"
</code></pre>
<p>All I want is for this to work:</p>
<pre><code>t <- "1:30:00 PM"
SOME COMMAND HERE HERE
# [1] "13:30:00"

Try With Resources Not Supported at This Language Level | <p>I'm using IntelliJ IDEA Ultimate 2016.2.1, have set Project SDK to my 1.8 version, Project Language Level to 8, Module SDK to my 1.8 version, and JDK home path to /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home.</p>
<p>I have restarted the IDE.</p>
<p>Still, I am getting ugly warnings about try-with-resources not supported at this language level. I have not used less than language level 8 in IntelliJ so this can't be due to something not refreshing. I am using a gradle build configuration - cleaned built and tried to run - says I'm running 1.5 but I can't figure out where 1.5 is mentioned. In build.gradle i'm using:</p>
<pre><code> apply plugin: 'java'
apply plugin: 'application'
sourceCompatibility = 1.8
</code></pre>
<p>Should I file an IntelliJ bug or am I still missing something?</p>
<p>EDIT:</p>
<p>Running gradle in termianl outside of IntelliJ's system runs it fine. So the problem is IntelliJ related. </p> | 0 |
How to add new flaticons to my website? | <p>I have a website template which uses flaticons.

<pre><code>.flaticon-wand2:before {
content: "\e0fb";

.flaticon-wealth:before {
content: "\e0fc";
}
.flaticon-website34:before {
content: "\e0fd";
}
.flaticon-world-grid:before {
content: "\e0fe";

AWS Lambda function - convert PDF to Image | <p>I am developing application where user can upload some drawings in pdf format. Uploaded files are stored on S3. After uploading, files has to be converted to images. For this purpose I have created lambda function which downloads file from S3 to /tmp folder in lambda execution environment and then I call ‘convert’ command from imagemagick. </p>
<p><code>convert sourceFile.pdf targetFile.png</code></p>
<p>Lambda runtime environment is nodejs 4.3. Memory is set to 128MB, timeout 30 sec.</p>
<p>Now the problem is that some files are converted successfully while others are failing with the following error: </p>
<blockquote>
<p>{ [Error: Command failed: /bin/sh -c convert /tmp/sourceFile.pdf
/tmp/targetFile.png convert: <code>%s' (%d) "gs" -q -dQUIET -dSAFER -dBATCH

error/convert.c/ConvertImageCommand/3046. ] killed: false, code: 1,
signal: null, cmd: '/bin/sh -c convert /tmp/sourceFile.pdf
/tmp/targetFile.png' }</p>
</blockquote>
<p>At first I did not understand why this happens, then I tried to convert problematic files on my local Ubuntu machine with the same command. This is the output from terminal: </p>
<p><code>**** Warning: considering '0000000000 XXXXX n' as a free entry.
**** This file had errors that were repaired or ignored.
**** The file was produced by:
**** >>>> Mac OS X 10.10.5 Quartz PDFContext <<<<
**** Please notify the author of the software that produced this
**** file that it does not conform to Adobe's published PDF
**** specification.</code></p>
<p>So the message was very clear, but the file gets converted to png anyway. If I try to do <code>convert source.pdf target.pdf</code> and after that <code>convert target.pdf image.png</code>, file is repaired and converted without any errors. This doesn’t work with lambda. </p>
<p>Since the same thing works on one environment but not on the other, my best guess is that the version of Ghostscript is the problem. Installed version on AMI is 8.70. On my local machine Ghostsript version is 9.18.</p>
<p>My questions are: </p>
<ul>
<li>Is the version of ghostscript problem? Is this a bug with older
version of ghostscript? If not, how can I tell ghostscript (with or
without using imagemagick) to repair or ignore errors like it does on
my local environment?</li>
<li>If the old version is a problem, is it possible to build ghostscript
from source, create nodejs module and then use that version of
ghostscript instead the one that is installed?</li>
<li>Is there an easier way to convert pdf to image without using
imagemagick and ghostscript?</li>
</ul>
<p><strong>UPDATE</strong>
Relevant part of lambda code: </p>
<pre><code>var exec = require('child_process').exec;
var AWS = require('aws-sdk');
var fs = require('fs');
...
var localSourceFile = '/tmp/sourceFile.pdf';
var localTargetFile = '/tmp/targetFile.png';
var writeStream = fs.createWriteStream(localSourceFile);
writeStream.write(body);
writeStream.end();
writeStream.on('error', function (err) {
console.log("Error writing data from s3 to tmp folder.");
context.fail(err);
});
writeStream.on('finish', function () {
var cmd = 'convert ' + localSourceFile + ' ' + localTargetFile;
exec(cmd, function (err, stdout, stderr ) {
if (err) {
console.log("Error executing convert command.");
context.fail(err);
}
if (stderr) {
console.log("Command executed successfully but returned error.");
context.fail(stderr);
}else{
//file converted successfully - do something...
}
});
});

Setting xlim with dates in R | <p>I need to set the x-axis limit of a plot in R, but my values are dates (%m/%d/%Y format). How would I go about changing this? I am trying to plot trophic position vs. collection date. All of my collection dates are in date format (%m/%d/%Y)</p>

Matplotlib plot_surface transparency artefact | <p>I'm trying to plot a surface in 3D from a set of data which specifies the z-values. I get some weird transparency artefact though, where I can see through the surface, even though I set alpha=1.0.</p>
<p>The artefact is present both when plotting and when saved to file (both as png and pdf):
<a href="https://i.stack.imgur.com/2bXbI.png" rel="noreferrer"><img src="https://i.stack.imgur.com/2bXbI.png" alt="enter image description here"></a></p>
<p>I have tried changing the line width, and changing the number of strides from 1 to 10 (in the latter case, the surface is not visible though due to too rough resolution).</p>
<p><strong>Q: How can I get rid of this transparency?</strong></p>
<p>Here is my code:</p>
<pre><code>import sys
import numpy as np
import numpy.ma as ma
import matplotlib as mpl
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
y_label = r'x'
x_label = r'y'
z_label = r'z'
x_scale = 2.0*np.pi
y_scale = 2.0*np.pi
y_numPoints = 250
x_numPoints = 250
def quasiCrystal(x, y):
z = 0
for i in range(0,5):
z += np.sin(x * np.cos(float(i)*np.pi/5.0) +
y * np.sin(float(i)*np.pi/5.0))
return z
x = np.linspace(-x_scale, x_scale, x_numPoints)
y = np.linspace(-y_scale, y_scale, y_numPoints)
X,Y = np.meshgrid(x,y)
Z = quasiCrystal(X, Y)
f = plt.figure()
ax = f.gca(projection='3d')
surf = ax.plot_surface( X, Y, Z,
rstride=5, cstride=5,
cmap='seismic',
alpha=1,
linewidth=0,
antialiased=True,

ax.set_zlim3d(np.min(Z), np.max(Z))
f.colorbar(surf, label=z_label)
ax.set_xlabel(x_label)
ax.set_ylabel(y_label)

__file__ does not exist in Jupyter Notebook | <p>I'm on a <a href="https://en.wikipedia.org/wiki/IPython#Project_Jupyter" rel="noreferrer">Jupyter Notebook</a> server (v4.2.2) with Python 3.4.2 and
I want to use the global name <code>__file__</code>, because the notebook will be cloned from other users and in one section I have to run:</p>
<pre><code>def __init__(self, trainingSamplesFolder='samples', maskFolder='masks'):
self.trainingSamplesFolder = self.__getAbsPath(trainingSamplesFolder)

else:
return os.path.join(os.path.dirname(__file__), path)

<p>The <code>__getAbsPath(self, path)</code> checks if a <code>path</code> param is a relative or absolute path and returns the absolute version of <code>path</code>. So I can use the returned <code>path</code> safely later.</p>
<p>But I get the error</p>
<blockquote>
<p>NameError: name <code>'__file__'</code> is not defined</p>

<p>I searched for this error online and found the "solution" that I should better use <code>sys.argv[0]</code>, but <code>print(sys.argv[0])</code> returns</p>

Can we have a multi-page JPEG image? | <p>Can we have a multi-page JPEG image?</p>
<p>I have a TIFF image file with multiple pages, but it's too big and first thing comes to mind is to change it to JPEG format, however in JPEG I can see only first page. Therefore I realized only TIFF format allows multiple images in one file. Is that true?</p>
<p>Now I tried to apply different <code>EncoderParameters</code> to reduce the size of TIFF file but no luck. Has someone worked on this issue before? How did you manage to reduce the size of TIFF image?</p>
<p><code>Encoder.Quality</code> does not seem to work with TIFF at all.
<code>EncoderValue.CompressionLZW</code> is the best option to reduce the size, but I still want to reduce the size more.</p>
<p>Changing dpi to 50 reduced the size, but that made image too blurry.</p>

Safari not rendering SVGs to the desired size/height (SVGS are clipped) | <p>I have some responsive inline SVGs I made. Their sizes render as I want them to in Chrome, Firefox and Edge, but in Safari they escape their containers/are cut off. For some reason their containers doesn't stretch to accommodate them. The following screenshot demonstrates the unwanted, cut-off Safari rendering: </p>
<p><a href="https://i.stack.imgur.com/uKnNX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uKnNX.png" alt="SVGS don't fit"></a></p>
<p>There are known issues with SVG rendering in Safari, and I have tried all the fixes out there I have found to the best of my ability (<a href="https://benfrain.com/attempting-to-fix-responsive-svgs-in-desktop-safari/" rel="nofollow noreferrer">here</a>, <a href="https://stackoverflow.com/questions/17158717/svg-container-renders-wrong-size-in-safari-desktop-fine-in-chrome-ios">here</a>, <a href="https://stackoverflow.com/questions/26091989/svg-viewbox-height-issue-on-ios-safari">here</a>, and <a href="https://stackoverflow.com/questions/7570917/svg-height-incorrectly-calculated-in-webkit-browsers">here</a>), but I can't manage to make the containers fit the SVGs in Safari. It is in part because things are a little complicated with my javascript and I'm still a beginner, forgive me if my codepen is a bit messy. </p>
<p>This is my codepen. :<a href="http://codepen.io/ihatecoding/pen/Bzgqqa" rel="nofollow noreferrer">http://codepen.io/ihatecoding/pen/Bzgqqa</a></p>
<p>What my jquery does: it makes SVGs as large as possible until they take up 1/3 of the screen height, at that point it won't let them get taller.</p>
<p>To help you focus on what matters :</p>
<ul>
<li>The SVGs are all of class <code>.areaSVG</code> </li>
<li>The SVG parents/containers are always <code>.ey-col-svg</code> </li>
<li>The entire footer is <code>#indexFooter</code> </li>
<li>The main background image that is supposed to resize according to the height of the landing footer is <code>#section0img</code></li>
</ul>
<p>The current version that is working the best has the following format for the svg container:</p>
<pre><code>.ey-col-svg {
display: block;
max-height: calc(30vh - 1vw - 63px);
text-align: center;
box-sizing: content-box;
padding: 0;
margin: -2vh 0 0 0;
}
</code></pre>
<p>This is the css for the SVGs before the javascript makes them visible and adjusts their <code>height</code>:</p>
<pre><code>.areaSVG {
overflow: visible;
display: none;
box-sizing: content-box;
margin: 0;
padding: 1.6vh 0 1vh 0;
}
</code></pre>
<p>Again, to repeat The javascript I have currently implemented adjusts the <code>height</code> of the SVGs (whose class is <code>areaSVG</code>).</p>
<p>This is the most relevant part of my jQuery script; it controls the size of the the SVGs. As I mentioned above, this script makes the SVGs as large as possible until they take up 1/3 of the screen height, and at that point it won't let them get taller:</p>
<pre><code> function resizeSVG() {
// the row
var $linksRow = $('.ey-nav-bar');
// the text
var $areaText = $('.ey-text-content');
//the entire row below "research Area"
// the actual svg container
var $area = $('.areaSVG');
var scale = 0.6;
//the wrapper containing the svg div, its height and its width
var $eyCol = $(".ey-col-svg");
var eyWidth = $eyCol.width();
var eyHeight = $eyCol.height();
//the window
var winHeight = $(window).height();
var winWidth = $(window).width();
//max Height caclulated based on window
var maxHeight = .33 * winHeight;
// if the height of the column is less than the width, and below the max height
if (eyHeight < eyWidth && eyHeight < maxHeight)
//make the height of the svg the max heihgt
$area.height(maxHeight);
// use the scaling factor times the width of the svg wrapper
var imageWidth = scale * $eyCol.width();
// get the hight of the column
var imageHeight = $eyCol.height();
// will be the dimensions used to size lenth and width of the svg
var tot;
//apsect ratio of the screen (horizontal/vertical)
var ratio = winWidth / winHeight;
// if the screen is landscape or if the user has left the landing section
tot = imageWidth > imageHeight ? imageHeight: imageWidth;
maxTextHeight = maxHeight * .07;
maxTotHeight = maxHeight * .5;
if (tot < maxTotHeight)
{ $area.css("height", tot);
}
else
{
$area.css("height", maxTotHeight);
$areaText.css("height", maxTextHeight);
}
minLinksHeight = maxHeight * .8;
var linksHeight = $linksRow.height();
}
</code></pre>
<p><em>(Note: the resulting SVG heights are subsequently used by another function, not seen here, to control the size of the main image).</em> </p>
<p>This is my introductory formatting code for each inline svg:</p>
<pre><code> <svg class="areaSVG notFixed index" viewBox="20 0 37 75" xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">

PrimeNG datatable checkbox selection with pagination | <p>I'm trying to bring a data table layout with pagination that has checkbox selection for data in it. I'm able to select a page's data and when I move to another page, and select different set of data, the first page selection is lost. </p>

How to load Impala table directly to Spark using JDBC? | <p>I am trying to write a spark job with Python that would open a jdbc connection with Impala and load a VIEW directly from Impala into a Dataframe. This question is pretty close but in scala: <a href="https://stackoverflow.com/questions/26634853/calling-jdbc-to-impala-hive-from-within-a-spark-job-and-creating-a-table">Calling JDBC to impala/hive from within a spark job and creating a table</a></p>
<p>How do I do this? There are plenty of examples for other datasources such as MySQL, PostgreSQL, etc. but I haven't seen one for Impala + Python + Kerberos. An example would be of great help. Thank you!</p>
<p>Tried this with information from the web but it didn't work.</p>

How to use Metric value in Alias? | <p>I created a new Graph in Grafana that takes data from OpenTSDB.</p>
<p><a href="https://i.stack.imgur.com/nr2hA.png" rel="noreferrer"><img src="https://i.stack.imgur.com/nr2hA.png" alt="Add Panel Graph"></a></p>
<p>The <strong>Alias</strong> field has the following value: <code>Label $metric $tag_host</code>.</p>
<ul>
<li><p>when it is interpreted, it looks like this:</p>
<ul>
<li><code>Label $metric myhost1</code></li>
<li>...</li>
<li><code>Label $metric myhostn</code></li>
</ul></li>
<li><p>but I want to look like this:</p>
<ul>
<li><code>Label xyz myhost1</code></li>
<li>...</li>
<li><code>Label xyz myhostn</code>
where <code>xyz</code> is the value of the <strong>Metric</strong> field.</li>
</ul></li>
</ul>
<p>So, for a key (E.g.: <code>host</code>) in <strong>Tags</strong>, I can use <code>$tag_<key></code> (E.g.: <code>$tag_host</code>) in <strong>Alias</strong>.</p>
<p>I want to achieve the same behavior for the hard-coded <strong>Metric</strong> value (E.g.: <code>xyz</code>), such that if someone wants to change the Metric value in the future from <code>xyz</code> to <code>abc</code>, the Alias should be updated automatically.</p>
<p>I tried to use:</p>
<ul>
<li><code>$metric</code></li>
<li><code>$Metric</code></li>
<li><code>$tag_metric</code></li>
</ul>
<p>but they didn't work.</p>
<p><a href="https://i.stack.imgur.com/1eXOD.png" rel="noreferrer"><img src="https://i.stack.imgur.com/1eXOD.png" alt="Grafana Metrics"></a></p>
<p>Is it possible to use the <strong>Metric</strong> value in <strong>Alias</strong> without hard-coding in Alias (the hard-coding from Metric is enough)?</p> | 0 |
SQLite query to delete from multiple tables | <p>I use a query to retrieve a list of tables with a specific column name:</p>
<pre><code>select name from sqlite_master where type='table' and sql like '%unique_col_id%';
</code></pre>
<p>So, it return a list of table names for example, table_1, table_2, table_3..</p>
<p>I would like to delete all rows in the above tables with unique_col_id equal to specific value:</p>
<pre><code>DELETE FROM table_1 where unique_col_id=3;
DELETE FROM table_2 where unique_col_id=3;
DELETE FROM table_3 where unique_col_id=3;
</code></pre>
<p>Is there a way to delete all table in one query? I mean to integrate both queries (search the table and delete all of them with unique_col_id=3...)</p>

Oracle - How to *correctly* convert from EST/EDT to GMT? | <p>I have a query that is doing some time zone conversions. As an example, I want to convert from an <code>EST</code> time to <code>GMT</code>:</p>
<p>For the EDT time of <code>3/13/2016 @2:00 AM</code> (immediately following the EST->EDT changeover) I should get a GMT time of <code>3/13/2016 7:00:00 AM</code> (<a href="http://www.worldtimebuddy.com/est-to-gmt-converter" rel="nofollow">verified here</a> for the date of 3/13/2016 @2am). Instead I am getting <code>3/13/2016 6:00:00 AM</code> from using this query:</p>
<pre><code>SELECT NEW_TIME(TO_DATE('2016/3/13 02:00:00 AM',
'YYYY/MM/DD HH:MI:SS AM'),'EDT','GMT')
FROM DUAL;
</code></pre>
<p>For the EST time of <code>3/13/2016 @1:00AM</code> (one second before the changeover) I am getting what appears to be the correct result:</p>
<pre><code>SELECT NEW_TIME(TO_DATE('2016/3/13 01:59:59 AM',
'YYYY/MM/DD HH:MI:SS AM'),'EST','GMT')
FROM DUAL;
</code></pre>
<p>Result:</p>
<pre><code>3/13/2016 6:59:59 AM
</code></pre>
<p>What am I doing wrong here? I have read the Oracle documentation on NEW_TIME and have tried switching the EDT/EST with the GMT (based on the one example they have at the bottom of the page) but that gives me even more odd results.</p> | 0 |
How can I draw a half arrow with asterisks in java? | <p>I am in my first java class, and I am trying to draw a half arrow using asterisks. I am supposed to use a nested loop where the inner loop draws the *s and the outer loop iterates the number of times equal to the height of the arrow base. I have learned if-else, while loops, and for loops. </p>
<p>So far, I have been able to correctly draw the arrow for input values of<br>
arrow base height: 5<br>
arrow base width: 2<br>
arrow head width: 4 </p>
<p>When I try to add a while loop as the outer loop, the program times out. I am at a loss. </p>
<p>The next input I need to use is 2, 3, 4. My code gets the height of the base right (2), but not the width. </p>
<p>The last input I need is 3, 3, 7. My code gets none of that right at all. This is what I have so far.</p>
<p>What kind of loops should I be using to get the widths correct?</p>
<pre><code> Scanner scnr = new Scanner(System.in);
int arrowBaseHeight = 0;
int arrowBaseWidth = 0;
int arrowHeadWidth = 0;
int i = 0;
System.out.println("Enter arrow base height: ");
arrowBaseHeight = scnr.nextInt();
System.out.println("Enter arrow base width: ");
arrowBaseWidth = scnr.nextInt();
System.out.println("Enter arrow head width: ");
arrowHeadWidth = scnr.nextInt();
for (i = 1; i <= arrowBaseHeight; ++i) {
// Draw arrow base (height = 3, width = 2)
System.out.println("**");
}
// Draw arrow head (width = 4)
System.out.println("****");
System.out.println("***");
System.out.println("**");
System.out.println("*");

Data Conversion Error while applying a function to each row in pandas Python | <p>I have a data frame in pandas in python which resembles something like this - </p>

8 53 91 0.264151
9 1 2 0.000000

<p>Now I want to apply a function to each row of this dataframe The function is written as this - </p>
<pre><code>def findCluster(clusterModel,data):
return clusterModel.predict(data)
</code></pre>
<p>I apply this function to each row in this manner - </p>
<pre><code>df_fil.apply(lambda x : findCluster(cluster_all,x.reshape(1,-1)),axis=1)
</code></pre>
<p>When I run this code, I get a warning saying - </p>
<blockquote>
<p>DataConversionWarning: Data with input dtype object was converted to float64.</p>
<p>warnings.warn(msg, DataConversionWarning)</p>
</blockquote>
<p>This warning is printed once for each row. Since, I have around 450K rows in my data frame, my computer hangs while printing all these warning messages that too on ipython notebook.</p>
<p>But to test my function I created a dummy dataframe and tried applying the same function on that and it works well. Here is the code for that - </p>
<pre><code>t = pd.DataFrame([[10.35,100.93,0.15],[10.35,100.93,0.15]])
t.apply(lambda x:findCluster(cluster_all,x.reshape(1,-1)),axis=1)

How do I store JWT and send them with every request using react | <p>So happy right know because I got my basic registration/authentication system going on.</p>
<p>so basically I got this :</p>
<pre><code>app.post('/login', function(req,res) {
Users.findOne({
email: req.body.email
}, function(err, user) {
if(err) throw err;
if(!user) {
res.send({success: false, message: 'Authentication Failed, User not found.'});
} else {
//Check passwords
checkingPassword(req.body.password, user.password, function(err, isMatch) {
if(isMatch && !err) {
//Create token
var token = jwt.sign(user,db.secret, {
expiresIn: 1008000
});
res.json({success: true, jwtToken: "JWT "+token});
} else {
res.json({success: false, message: 'Authentication failed, wrong password buddy'});
}
});
}
});
});
</code></pre>
<p>Then I secure my /admin routes and with POSTMAN whenever I send a get request with the jwt in the header everything works perfectly.</p>
<p>Now here is the tricky part, basically When i'm going to login if this a sucess then redirect me to the admin page, and everytime I try to access admin/* routes I want to send to the server my jwToken but the problem is, how do I achieve that ? I'm not using redux/flux, just using react/react-router.</p>
<p>I don't know how the mechanic works.</p>

Full-width image inside container in Bootstrap 4 | <p>I am using Bootstrap 4 and I have a template layout with</p>
<pre><code><div class="navbar">
...
</div>
<div class="container">
{{content}}
</div>
</code></pre>
<p>This works in almost all cases. However, sometimes I want an image in the content to take up the full width, but this is not possible due to the <code>.container</code> which uses <code>left-padding</code> and <code>right-padding</code>.</p>
<p>I could solve this by adding the <code>.container</code> class in each view at the right places instead of in my template layout file, but this will become quite annoying. Especially if I have a CMS where different authors can write articles, and if they want a full-width image in the middle of their article, they have to write raw html to be something like</p>
<pre><code><div class="container">
some text
</div>
<div class="full-width-image">
<img src="" alt="">
</div>
<div class="container">
more text
</div>
..
</code></pre>

Serializing image stream using protobuf | <p>I have two programs in Ubuntu: a C++ program (TORCS game) and a python program. The C++ program always generates images. I want to transfer these real-time images into python(maybe the numpy.ndarray format). So I think that maybe using Google protobuf to serialize the image to string and send string to python client by ZMQ is a feasible method.</p>
<p><strong>Question</strong>: which value type is suitable for the image(a pointer) in <code>.proto</code> file? In another words, which value type I should use to replace <code>string</code> type in the below example?</p>
<pre><code>message my_image{
repeated string image = 1
}
</code></pre>
<p>This is the way I write image to memory (uint8_t* image_data):</p>
<pre><code>glReadPixels(0, 0, width, height, GL_RGB, GL_UNSIGNED_BYTE, (GLvoid*)image_data);
</code></pre>
<p>At last, maybe there is a better way to transfer image (in the memory) to a python client?</p>
<p>Any suggestions are appreciated.</p> | 0 |
Is there a difference between ? and * in cron expressions? Strange example | <p>I have the following cron expression in my system:</p>
<pre><code>0 0 0/1 1/1 * ? *
</code></pre>
<p>and you know what? I have no idea what it means. The guy who has written it is on his holiday for the next 2 weeks so I have to find out on myself. The documentation can be found <a href="https://docs.oracle.com/cd/E12058_01/doc/doc.1014/e12030/cron_expressions.htm#CIHBEEFA" rel="noreferrer">here</a></p>
<p>According to the <a href="https://docs.oracle.com/cd/E12058_01/doc/doc.1014/e12030/cron_expressions.htm#CIHBEEFA" rel="noreferrer">documentation</a> we have:</p>
<pre><code>* * * * * * *
| | | | | | |
| | | | | | +-- Year (range: 1970-2099)
| | | | | +---- Day of the Week (range: 1-7 or SUN-SAT)
| | | | +------ Month of the Year (range: 0-11 or JAN-DEC)
| | | +-------- Day of the Month (range: 1-31)
| | +---------- Hour (range: 0-23)
| +------------ Minute (range: 0-59)
+-------------- Second (range: 0-59)
</code></pre>
<p>Ok, let me tell you what I think: I believe that the expression means:</p>
<pre><code>start when:
seconds: 0
minutes: 0
hours: 0
dayOfMonth 1
monthOfYear any
dayOfWeek any
year any
run every:
1 hour
1 dayOfWeek
when:
dayOfWeek same as on first execution
</code></pre>
<p>However available cron expression monitors says that it simply means every hour.
As the one who has written that is Senior Java Dev, he must have known any reason for writing such expression instead of:</p>
<pre><code>0 0 * * * * *
</code></pre>
<p>We use <code>org.springframework.scheduling.quartz.QuartzJobBean</code>.</p>
<p><strong>Short summary</strong></p>
<p>Well, I think that my question is: what is the difference between <code>0 0 0/1 1/1 * ? *</code> and <code>0 0 * * * * *</code>?</p>
<p><strong>Edit:</strong></p>

Docker doesn't resolve hostname | <p>I need to know the hostnames (or ip addresses) of some container running on the same machine.
As I already commented <a href="https://stackoverflow.com/questions/26269870/how-do-docker-containers-resolve-hostname-of-other-docker-containers-running-on/26274232#comment65923973_26274232">here</a> (but with no answer yet), I use <code>docker-compose</code>.

<blockquote>
<p>Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by them at a hostname identical to the container name.</p>

require() node module from Electron renderer process served over HTTP | <p>Typically, in an Electron app, you can <code>require</code> node modules from both the main process and the renderer process:</p>
<pre><code>var myModule = require('my-module');
</code></pre>
<p>However, this doesn't seem to work if the page was loaded via HTTP instead of from the local filesystem. In other words, if I open a window like this:</p>
<pre><code>win.loadURL(`file://${__dirname}/index.html`);
</code></pre>
<p>I can <code>require</code> a node module without problems. But if I instead open a window like this:</p>
<pre><code>win.loadURL(`http://localhost:1234/index.html`);
</code></pre>
<p>I no longer can <code>require</code> node modules inside my web page - I get <code>Uncaught Error: Cannot find module 'my-module'</code> in the web page's console. Is there any way to use node modules in an Electron page that was served over HTTP?</p>
<hr />
<p>A little context: My company is building an application that needs the ability to be hosted as a web application <em>and</em> inside an Electron shell. To make this simpler and consistent across both environments, my Electron app starts a local web server and opens the app hosted at <code>http://localhost:1234</code>. Now I'd like the ability to add spell checking/spelling suggestions into the application using <a href="https://www.npmjs.com/package/electron-spell-check-provider" rel="noreferrer"><code>electron-spell-check-provider</code></a>. This module needs to be imported and initialized inside the renderer process, so I'm trying to <code>require('electron-spell-check-provider')</code> inside my web page, but this fails with the <code>Cannot find module</code> error.</p> | 0 |

Python Argparse: Raw string input | <p>Apologies if this has been asked before, I did search for it but all hits seemed to be about python raw strings in general rather than regarding argparse.</p>
<p>Anyways, I have a code where the user feeds in a string and then this string is processed. However, I have a problem as I want my code to be able to differentiate between <code>\n</code> and <code>\\n</code> so that the user can control if they get a line break or <code>\n</code> appear in the output (respectively). </p>
<p>This in itself is quite simple, and I can get the logic working to check the string, etc. However, argparse doesn't seem to keep the input string raw. So if I were to write: <code>Here is a list:\nItem 1</code> it gets parsed as <code>Here is a list:\\nItem 1</code>. As the exact same thing gets parsed if I were to replace <code>\n</code> with <code>\\n</code> in the input string, it becomes impossible to differentiate between the two.</p>
<p>I could include a bodge (for example, I could make the user enter say <code>$\n</code> for <code>\n</code> to appear in the output, or just <code>\n</code> for a line break). But this is messy and complicates the usage of the code.</p>
<p>Is there a way to ensure the string being parsed by argparse is raw? (I.e. if I enter <code>\n</code> it parses <code>\n</code> and not <code>\\n</code>)</p>
<p>Again, sorry if this has been asked before, but I couldn't find an answer and after over an hour of trying to find an answer, I'm out of ideas (bar the bodge). Cheers in advance for any and all help.</p>
<p>Example code (sorry if this doesn't work, not sure how best to do example code for argparse!):</p>
<pre><code>import argparse
parser = argparse.ArgumentParser( description = 'Test.' )
parser.add_argument( 'text', action = 'store', type = str, help = 'The text to parse.' )
args = parser.parse_args( )
print( repr( args.text ) )

How to treat uppercase and lowercase words the same in Python | <p>Code:</p>
<pre><code>str1 = input("Please enter a full sentence: ")
print("Thank you, You entered:" , str1)
str2 = input("Now please enter a word included in your sentence in anyway you like: ")
if str2 in str1:
print("That word was found!")
else:
print("Sorry, that word was not found")
</code></pre>
<p>I have done some research on forums etc and the only solutions i can find for this subject are converting words into uppercase/lowercase. I don't want to do it like that.</p>
<p>I want something that will ignore the fact that it is uppercase or lowercase and will assume it to be the same word, so when someone inputs a sentence it will automatically assume it t be the same word. For example: (Treat = treat, TREAT, TreAT etc). So it will essentially read the characters in the word and will ignore the uppercase/lowercase letters. </p>
<p>I do have something (string.ascii_letters) which i think might do it, but if anyone know any better way of doing it then that would be greatly appreciated! :)</p> | 0 |
