There's nothing wrong with your query, but you could also do it this way:
WITH internalQuery (Amount)
AS
(
SELECT (0)
FROM DocumentOutputItems
GROUP BY DocumentId, DocumentSessionId
)
SELECT COUNT(*) AS NumberOfDistinctRows
FROM internalQuery
Read one character at a time (using getc(stdin)
) and grow the string (realloc
) as you go.
Here's a function I wrote some time ago. Note it's intended only for text input.
char *getln()
{
char *line = NULL, *tmp = NULL;
size_t size = 0, index = 0;
int ch = EOF;
while (ch) {
ch = getc(stdin);
/* Check if we need to stop. */
if (ch == EOF || ch == '\n')
ch = 0;
/* Check if we need to expand. */
if (size <= index) {
size += CHUNK;
tmp = realloc(line, size);
if (!tmp) {
free(line);
line = NULL;
break;
}
line = tmp;
}
/* Actually store the thing. */
line[index++] = ch;
}
return line;
}
I had the same problem on Mac 10.7.5 with git version 1.7.12.4
When I ran gitk I got an error:
"Error in startup script: expected version number but got "Git-37)"
while executing
"package vcompare $git_version "1.6.6.2""
invoked from within
"if {[package vcompare $git_version "1.6.6.2"] >= 0} {
set show_notes "--show-notes"
}"
(file "/usr/bin/gitk" line 11587)
When I looked at the code in gitk I saw the line that sets the version.
set git_version [join [lrange [split [lindex [exec git version] end] .] 0 2] .]
This somehow parsed the git version results to Git-37
instead of 1.7.12.4
I just replaced the git_version line with:
set git_version "1.7.12.4"
I use the lattice
package for almost everything I plot in R and it has a corresponing plot to persp
called wireframe
. Let data
be the way Sven defined it.
wireframe(z ~ x * y, data=data)
Or how about this (modification of fig 6.3 in Deepanyan Sarkar's book):
p <- wireframe(z ~ x * y, data=data)
npanel <- c(4, 2)
rotx <- c(-50, -80)
rotz <- seq(30, 300, length = npanel[1]+1)
update(p[rep(1, prod(npanel))], layout = npanel,
panel = function(..., screen) {
panel.wireframe(..., screen = list(z = rotz[current.column()],
x = rotx[current.row()]))
})
Since this post continues to draw attention I want to add the OpenGL way to make 3-d plots too (as suggested by @tucson below). First we need to reformat the dataset from xyz-tripplets to axis vectors x
and y
and a matrix z
.
x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z
library(rgl)
persp3d(x, y, z, col="skyblue")
This image can be freely rotated and scaled using the mouse, or modified with additional commands, and when you are happy with it you save it using rgl.snapshot
.
rgl.snapshot("myplot.png")
You can try the following: (This may be duplicate of the answers posted but I have added description)
Display all users that can be seen by the current user:
SELECT * FROM all_users;
Display all users in the Database:
SELECT * FROM dba_users;
Display the information of the current user:
SELECT * FROM user_users;
Lastly, this will display all users that can be seen by current users based on creation date:
SELECT * FROM all_users
ORDER BY created;
The selected answer refers only to iOS. For both platforms, you can use the following component:
import React, { Component, PropTypes } from 'react';
import {
Linking,

StyleSheet
} from 'react-native';
export default class HyperLink extends Component {
constructor(){
super();
this._goToURL = this._goToURL.bind(this);
}
static propTypes = {
url: PropTypes.string.isRequired,
title: PropTypes.string.isRequired,
}
render() {
const { title} = this.props;
return(
<Text style={styles.title} onPress={this._goToURL}>
> {title}
</Text>
);
}
_goToURL() {
const { url } = this.props;
Linking.canOpenURL(url).then(supported => {
if (supported) {
Linking.openURL(this.props.url);
} else {
console.log('Don\'t know how to open URI: ' + this.props.url);
}
});
}
}
const styles = StyleSheet.create({
title: {
color: '#acacac',
fontWeight: 'bold'
}
});

It is also possible to use FormData()
. But you need to set contentType
as false
:
var data = new FormData();
data.append('name', 'Bob');
function sendData() {
$.ajax({
url: '/helloworld',
type: 'POST',
contentType: false,
data: data,
dataType: 'json'
});
}
In new version of jquery, could done it via following steps:
serializeArray()
push()
or similar methods to add additional params to the array,$.param(arr)
to get serialized string, which could be used as jquery ajax's data
param.Example code:
var paramArr = $("#loginForm").serializeArray();
paramArr.push( {name:'size', value:7} );
$.post("rest/account/login", $.param(paramArr), function(result) {
// ...
}
Add !important
rule to display: table
of your .v-center
class.
.v-center {
display:table !important;
border:2px solid gray;
height:300px;
}
Your display property is being overridden by bootstrap to display: block
.
I got this error message with a much more recent ssis version (vs 2015 enterprise, i think it's ssis 2016). I will comment here because this is the first reference that comes up when you google this error message. I think it happens mostly with character columns when the source character size is larger than the target character size. I got this message when I was using an ado.net input to ms sql from a teradata database. Funny because the prior oledb writes to ms sql handled all the character conversion perfectly with no coding overrides. The colid number and the a corresponding Destination Input column # you sometimes get with the colid message are worthless. It's not the column when you count down from the top of the mapping or anything like that. If I were microsoft, I'd be embarrased to give an error message that looks like it's pointing at the problem column when it isn't. I found the problem colid by making an educated guess and then changing the input to the mapping to "Ignore" and then rerun and see if the message went away. In my case and in my environment I fixed it by substr( 'ing the Teradata input to the character size of the ms sql declaration for the output column. Check and make sure your input substr propagates through all you data conversions and mappings. In my case it didn't and I had to delete all my Data Conversion's and Mappings and start over again. Again funny that OLEDB just handled it and ADO.net threw the error and had to have all this intervention to make it work. In general you should use OLEDB when your target is MS Sql.
If you already have a JavaScript function called showImage
defined to show the image, you can link as such:
<a href="javascript:showImage()">show image</a>
If you need help defining the function, I would try:
function showImage() {
var img = document.getElementById('myImageId');
img.style.visibility = 'visible';
}
Or, better yet,
function setImageVisible(id, visible) {
var img = document.getElementById(id);
img.style.visibility = (visible ? 'visible' : 'hidden');
}
Then, your links would be:
<a href="javascript:setImageVisible('myImageId', true)">show image</a>
<a href="javascript:setImageVisible('myImageId', false)">hide image</a>
Try this, it works
$this->request = $this->container->get('request_stack')->getCurrentRequest();

Use time.sleep()
:
import time
time.sleep(50 / 1000)
See the Python documentation: https://docs.python.org/library/time.html#time.sleep
I had this same problem and solved it by adding an event handler for the play action in addition to the click action. I hide the controls while playing to avoid the pause button issue.
var v = document.getElementById('videoID');
v.addEventListener(
'play',
function() {
v.play();
},
false);
v.onclick = function() {
if (v.paused) {
v.play();
v.controls=null;
} else {
v.pause();
v.controls="controls";
}
};
Seeking still acts funny though, but at least the confusion with the play control is gone. Hope this helps.
Anyone have a solution to that?
Here's a method I wrote to check if an URL exists or not. I had a requirement to add a request header. It's Groovy but should be fairly simple to adapt to Java. Essentially I'm using the org.springframework.web.client.RestTemplate#execute(java.lang.String, org.springframework.http.HttpMethod, org.springframework.web.client.RequestCallback, org.springframework.web.client.ResponseExtractor<T>, java.lang.Object...)
API method. I guess the solution you arrive at depends at least in part on the HTTP method you want to execute. The key take away from example below is that I'm passing a Groovy closure (The third parameter to method restTemplate.execute()
, which is more or less, loosely speaking a Lambda in Java world) that is executed by the Spring API as a callback to be able to manipulate the request object before Spring executes the command,
boolean isUrlExists(String url) {
try {
return (restTemplate.execute(url, HttpMethod.HEAD,
{ ClientHttpRequest request -> request.headers.add('header-name', 'header-value') },
{ ClientHttpResponse response -> response.headers }) as HttpHeaders)?.get('some-response-header-name')?.contains('some-response-header-value')
} catch (Exception e) {
log.warn("Problem checking if $url exists", e)
}
false
}
One solution is with JQuery:
$(document).ready(
function () {
$('#mycheckboxId').click(function () {
// here the action or function to call
});
}
);
select replace(wm_concat(new),',','-') exp_res from (select distinct initcap(substr(name,decode(level,1,1,instr(name,'-',1,level-1)+1),decode(level,(length(name)-length(replace(name,'-','')))+1,9999,instr(name,'-',1,level)-1-decode(level,1,0,instr(name,'-',1,level-1))))) new from table;
connect by level<= (select (length(name)-length(replace(name,'-','')))+1 from table));
Try this test:
any(substring in string for substring in substring_list)
It will return True
if any of the substrings in substring_list
is contained in string
.
Note that there is a Python analogue of Marc Gravell's answer in the linked question:
from itertools import imap
any(imap(string.__contains__, substring_list))
In Python 3, you can use map
directly instead:
any(map(string.__contains__, substring_list))
Probably the above version using a generator expression is more clear though.
Try the following:
$.ajax({
url: _saveDeviceUrl
, type: 'POST'
, contentType: 'application/json'
, dataType: 'json'
, data: {'myArray': postData}
, success: _madeSave.bind(this)
//, processData: false //Doesn't help
});
delete the assemeblyinfo.cs file from project under properties menu and rebulid it.
Using Query parameter
<a href="edit.jsp?userId=${user.id}" />
Using Hidden variable .
<form method="post" action="update.jsp">
...
<input type="hidden" name="userId" value="${user.id}">
you can send Using Session object.
session.setAttribute("userId", userid);
These values will now be available from any jsp as long as your session is still active.
int userid = session.getAttribute("userId");
In Swift, the == operator is equivalent to Objective C's isEqual: method (it calls the isEqual method instead of just comparing pointers, and there's a new === method for testing that the pointers are the same), so you can just write this as:
if username == "" || password == ""
{
println("Sign in failed. Empty character")
}
You can use the function int atoi (const char * str);
.
You need to include #include <stdlib.h>
and use the function in this way:int x = atoi(argv[1]);
Here more information if needed: atoi - C++ Reference

Your question title and your question body are different. Ruby does not have a starts_with? method. Rails, which is a Ruby framework, however, does, as sepp2k states. See his comment on his answer for the link to the documentation for it.
You could always use a regular expression though:
if SomeString.match(/^abc/)
# SomeString starts with abc
^
means "start of string" in regular expressions
My question is: Why is not calling
return
faster
It’s faster because return
is a (primitive) function in R, which means that using it in code incurs the cost of a function call. Compare this to most other programming languages, where return
is a keyword, but not a function call: it doesn’t translate to any runtime code execution.
That said, calling a primitive function in this way is pretty fast in R, and calling return
incurs a minuscule overhead. This isn’t the argument for omitting return
.
or better, and thus preferable?
Because there’s no reason to use it.
Because it’s redundant, and it doesn’t add useful redundancy.
To be clear: redundancy can sometimes be useful. But most redundancy isn’t of this kind. Instead, it’s of the kind that adds visual clutter without adding information: it’s the programming equivalent of a filler word or chartjunk).
Consider the following example of an explanatory comment, which is universally recognised as bad redundancy because the comment merely paraphrases what the code already expresses:
# Add one to the result
result = x + 1
Using return
in R falls in the same category, because R is a functional programming language, and in R every function call has a value. This is a fundamental property of R. And once you see R code from the perspective that every expression (including every function call) has a value, the question then becomes: “why should I use return
?” There needs to be a positive reason, since the default is not to use it.
One such positive reason is to signal early exit from a function, say in a guard clause:
f = function (a, b) {
if (! precondition(a)) return() # same as `return(NULL)`!
calculation(b)
}
This is a valid, non-redundant use of return
. However, such guard clauses are rare in R compared to other languages, and since every expression has a value, a regular if
does not require return
:
sign = function (num) {
if (num > 0) {
1
} else if (num < 0) {
-1
} else {
0
}
}
We can even rewrite f
like this:
f = function (a, b) {
if (precondition(a)) calculation(b)
}
… where if (cond) expr
is the same as if (cond) expr else NULL
.
Finally, I’d like to forestall three common objections:
Some people argue that using return
adds clarity, because it signals “this function returns a value”. But as explained above, every function returns something in R. Thinking of return
as a marker of returning a value isn’t just redundant, it’s actively misleading.
Relatedly, the Zen of Python has a marvellous guideline that should always be followed:
Explicit is better than implicit.
How does dropping redundant return
not violate this? Because the return value of a function in a functional language is always explicit: it’s its last expression. This is again the same argument about explicitness vs redundancy.
In fact, if you want explicitness, use it to highlight the exception to the rule: mark functions that don’t return a meaningful value, which are only called for their side-effects (such as cat
). Except R has a better marker than return
for this case: invisible
. For instance, I would write
save_results = function (results, file) {
# … code that writes the results to a file …
invisible()
}
But what about long functions? Won’t it be easy to lose track of what is being returned?
Two answers: first, not really. The rule is clear: the last expression of a function is its value. There’s nothing to keep track of.
But more importantly, the problem in long functions isn’t the lack of explicit return
markers. It’s the length of the function. Long functions almost (?) always violate the single responsibility principle and even when they don’t they will benefit from being broken apart for readability.
Solution with utl_encode.base64_encode
and utl_encode.base64_decode
have one limitation, they work only with strings up to 32,767 characters/bytes.
In case you have to convert bigger strings you will face several obstacles.
BASE64_ENCODE
the function has to read 3 Bytes and transform them. In case of Multi-Byte characters (e.g. öäüè€
stored at UTF-8, aka AL32UTF8
) 3 Character are not necessarily also 3 Bytes. In order to read always 3 Bytes you have to convert your CLOB
into BLOB
first.BASE64_DECODE
. The function has to read 4 Bytes and transform them into 3 Bytes. Those 3 Bytes are not necessarily also 3 CharactersCR
and/or LF
) character each 64 characters. Such new-line characters have to be ignored while decoding.Taking all this into consideration the full featured solution could be this one:

I have a struct KeyValuePairSerializable

[XmlText]
public V Value { get; set; }
public override string ToString()

}
Then, the XML serialization of a Dictionary
property is by:
[XmlIgnore]
public Dictionary<string, string> Parameters { get; set; }
[XmlArray("Parameters")]
[XmlArrayItem("Pair")]

{
return Parameters?.Select(p => new KeyValuePairSerializable<string, string>(p)).ToArray();
}
set

}
}
Just the property must be the array, not the List.
Nice answers. You could also set Jobs (i.e., commands) with "Crontab" for more flexibility (which provides different options to run scripts, loggin the outputs, etc.), although it requires more time to be understood and set properly:
Using '@reboot' you can Run a command once, at startup.
Wrapping up:
run $ sudo crontab -e -u root
And add a line at the end of the file with your command as follows:
@reboot sudo searchd

you can use coroutines as well, like this one :
CoroutineScope(Dispatchers.Main).launch {
delay(10)
val width = view.width()
val height= view.height()
// do your job ....
}
You have to modify your server side code, as given below
public class CorsResponseFilter implements ContainerResponseFilter {
@Override
public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
throws IOException {
responseContext.getHeaders().add("Access-Control-Allow-Origin","*");
responseContext.getHeaders().add("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT");
}
}
Instead of:
void addStudent(person)
{
return;
}
try this:
void addStudent(student person)
{
return;
}
Since you have already declared a structure called 'student' you don't necessarily have to specify so in the function implementation as in:
void addStudent(struct student person)
{
return;
}
seems you need to link with the obj file that implements tolayer5()
Update: your function declaration doesn't match the implementation:
void tolayer5(int AorB, struct msg msgReceived)
void tolayer5(int, char data[])
So compiler would treat them as two different functions (you are using c++). and it cannot find the implementation for the one you called in main().

I've been in this (Twitter) industry for a long time and witnessed lots of changes in Twitter API and documentation. I would like to clarify one thing to you. There is no way to surpass 3200 tweets limit. Twitter doesn't provide this data even in its new premium API.
The only way someone can surpass this limit is by saving the tweets of an individual Twitter user.
There are tools available which claim to have a wide database and provide more than 3200 tweets. Few of them are followersanalysis.com, keyhole.co which I know of.
Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:
If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php
Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an
iframe
embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.
The best solution I created is to simply use google as the ssl proxy...
https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky
Tested and works in firefox.
Other Methods:
Use a Third party such as embed.ly (but it it really only good for well known http APIs).
Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)
https://example.com
That has a iframe linking to...
https://example.com/utilities/redirect.html
Which has a simple js redirect script like...
document.location.href ="http://thenonsslsite.com";
Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.
You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.
Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).
The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.
Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.
Trying to uninstall Python with
brew uninstall python
will not remove the natively installed Python but rather the version installed with brew
.
My idea:
public enum SomeKindOfEnum{
ENUM_NAME("initialValue");
private String value;
SomeKindOfEnum(String value){
this.value = value;
}
public boolean equalValue(String passedValue){
return this.value.equals(passedValue);
}
}
And if u want to check Value u write:
SomeKindOfEnum.ENUM_NAME.equalValue("initialValue")
Kinda looks nice for me :). Maybe somebody will find it useful.

You can also try this: Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37 In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.
Html.Label
gives you a label for an input whose name matches the specified input text (more specifically, for the model property matching the string expression):
// Model
public string Test { get; set; }
// View
@Html.Label("Test")
// Output
<label for="Test">Test</label>
Html.LabelFor
gives you a label for the property represented by the provided expression (typically a model property):
// Model
public class MyModel
{
[DisplayName("A property")]
public string Test { get; set; }
}
// View
@model MyModel
@Html.LabelFor(m => m.Test)
// Output
<label for="Test">A property</label>
Html.LabelForModel
is a bit trickier. It returns a label whose for
value is that of the parameter represented by the model object. This is useful, in particular, for custom editor templates. For example:
// Model
public class MyModel
{
[DisplayName("A property")]
public string Test { get; set; }
}
// Main view
@Html.EditorFor(m => m.Test)
// Inside editor template
@Html.LabelForModel()
// Output
<label for="Test">A property</label>

This is my LDAP Java login test application supporting LDAP:// and LDAPS:// self-signed test certificate. Code is taken from few SO posts, simplified implementation and removed legacy sun.java.* imports.
Usage
I have run this in Windows7 and Linux machines against WinAD directory service. Application prints username and member groups.
$ java -cp classes test.LoginLDAP url=ldap://1.2.3.4:389 [email protected] password=mypwd
$ java -cp classes test.LoginLDAP url=ldaps://1.2.3.4:636 [email protected] password=mypwd
Test application supports temporary self-signed test certificates for ldaps:// protocol, this DummySSLFactory accepts any server cert so man-in-the-middle is possible. Real life installation should import server certificate to a local JKS keystore file and not using dummy factory.
Application uses enduser's username+password for initial context and ldap queries, it works for WinAD but don't know if can be used for all ldap server implementations. You could create context with internal username+pwd then run queries to see if given enduser is found.

I get into the same issue even after moving the composer.phar
to '/usr/local/bin/composer' using the following command in amazon linux.
mv composer.phar /usr/local/bin/composer
I used the following command to create a alias for the composer file. So now its running globally.
alias composer='/usr/local/bin/composer'
I don't know whether this will work in OS-X. But when i search with this issue i get this link. So I'm just posting here. Hope this will help someone.
Let me clarify what you're talking about: you want to test Foo
in a testcase, which calls external method uses_some_other_method
. Instead of calling the actual method, you want to mock the return value.
class Foo:
def method_1():
results = uses_some_other_method()
def method_n():
results = uses_some_other_method()
Suppose the above code is in foo.py
and uses_some_other_method
is defined in module bar.py
. Here is the unittest:
import unittest
import mock
from foo import Foo
class TestFoo(unittest.TestCase):
def setup(self):
self.foo = Foo()
@mock.patch('foo.uses_some_other_method')
def test_method_1(self, mock_method):
mock_method.return_value = 3
self.foo.method_1(*args, **kwargs)
mock_method.assert_called_with(*args, **kwargs)
If you want to change the return value every time you passed in different arguments, mock
provides side_effect
.
There is comma missing in your tuple.
insert the comma between the tuples as shown:
pack_size = (('1', '1'),('3', '3'),(b, b),(h, h),(d, d), (e, e),(r, r))
Do the same for all
If you want to check through a server.php or whatever, you want to call it with the following:
<?php
phpinfo(INFO_VARIABLES);
?>
or
<?php
header("Content-type: text/plain");
print_r($_SERVER);
?>
Then access it with all the valid URLs for your site and check out the difference.
My project was building fine until I updated to Xcode 10.1. After the Xcode update, started getting Lexical or preprocessor Issue
errors on build. Some XCDataModel header files could not be found.
This fixed the issue.
Go to Build Settings, Header Search Paths
Change the appropriate value from $(SRCROOT) non-recursive
to recursive
.
This ensures that subfolders are also searched for headers during build.
<a [ngClass]="{'class1':array.status === 'active','class2':array.status === 'idle','class3':array.status === 'inactive',}">
You can do this:
app-routing-modules.ts:
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { PowerBoosterComponent } from './component/power-booster.component';
export const routes: Routes = [
{ path: 'pipeexamples',component: PowerBoosterComponent,
data:{ name:'shubham' } },
];
@NgModule({
imports: [ RouterModule.forRoot(routes) ],
exports: [ RouterModule ]
})
export class AppRoutingModule {}
In this above route, I want to send data via a pipeexamples path to PowerBoosterComponent.So now I can receive this data in PowerBoosterComponent like this:
power-booster-component.ts
import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params, Data } from '@angular/router';
@Component({
selector: 'power-booster',
template: `
<h2>Power Booster</h2>`
})
export class PowerBoosterComponent implements OnInit {
constructor(
private route: ActivatedRoute,
private router: Router
) { }
ngOnInit() {
//this.route.snapshot.data['name']
console.log("Data via params: ",this.route.snapshot.data['name']);
}
}
So you can get the data by this.route.snapshot.data['name']
.
Thanks @Harry the following code works for me:

The thing with compiling two .cpp files at the same time, it doesnt't mean they "know" about eachother. You will have to create a file, the "tells" your File1.cpp, there actually are functions and classes like ClassTwo. This file is called header-file and often doesn't include any executable code. (There are exception, e.g. for inline functions, but forget them at first) They serve a declarative need, just for telling, which functions are available.
When you have your File2.cpp
and include it into your File1.cpp
, you see a small problem:
There is the same code twice: One in the File1.cpp
and one in it's origin, File2.cpp
.
Therefore you should create a header file, like File1.hpp
or File1.h
(other names are possible, but this is simply standard). It works like the following:
//File1.cpp
void SomeFunc(char c) //Definition aka Implementation
{
//do some stuff
}
//File1.hpp
void SomeFunc(char c); //Declaration aka Prototype
And for a matter of clean code you might add the following to the top of File1.cpp
:
#include "File1.hpp"
And the following, surrounding File1.hpp
's code:
#ifndef FILE1.HPP_INCLUDED
#define FILE1.HPP_INCLUDED
//
//All your declarative code
//
#endif
This makes your header-file cleaner, regarding to duplicate code.
The ID of the two repos are both localSnap
; that's probably not what you want and it might confuse Maven.
If that's not it: There might be more repository
elements in your POM. Search the output of mvn help:effective-pom
for repository
to make sure the number and place of them is what you expect.
Include path of jar (jdbc driver) in classpath.
For a String constant you have no choice other than escaping via backslash.
Maybe you find the MyBatis project interesting. It is a thin layer over JDBC where you can externalize your SQL queries in XML configuration files without the need to escape double quotes.
There's an easy way to produce this error:
$joe = null;
$joe->anything();
Will render the error:
Fatal error: Call to a member function
anything()
on a non-object in /Applications/XAMPP/xamppfiles/htdocs/casMail/dao/server.php on line 23
It would be a lot better if PHP would just say,
Fatal error: Call from Joe is not defined because (a) joe is null or (b) joe does not define
anything()
in on line <##>.
Usually you have build your class so that $joe
is not defined in the constructor or
You can do this from the IPython API.

Installing XCode requires:
To install g++ *WITHOUT* having to download the MASSIVE 4.7G xCode install, try this package:
https://github.com/kennethreitz/osx-gcc-installer
The DMG files linked on that page are ~270M and much quicker to install. This was perfect for me, getting homebrew up and running with a minimum of hassle.
The github project itself is basically a script that repackages just the critical chunks of xCode for distribution. In order to run that script and build the DMG files, you'd need to already have an XCode install, which would kind of defeat the point, so the pre-built DMG files are hosted on the project page.
you can't use aliases from select list inside the WHERE clause (because of the Order of Evaluation of a SELECT statement)
also you cannot use OVER
clause inside WHERE clause - "You can specify analytic functions with this clause in the select list or ORDER BY clause." (citation from docs.oracle.com)
select *

staff_id, site_id, pay_level, date,
max(date) over (partition by staff_id) max_date

Since Dave asked for me to repeat my answer to Omitting all xsi and xsd namespaces when serializing an object in .NET, I have updated this post and repeated my answer here from the afore-mentioned link. The example used in this answer is the same example used for the other question. What follows is copied, verbatim.
After reading Microsoft's documentation and several solutions online, I have discovered the solution to this problem. It works with both the built-in XmlSerializer
and custom XML serialization via IXmlSerialiazble
.
To whit, I'll use the same MyTypeWithNamespaces
XML sample that's been used in the answers to this question so far.
[XmlRoot("MyTypeWithNamespaces", Namespace="urn:Abracadabra", IsNullable=false)]
public class MyTypeWithNamespaces
{
// As noted below, per Microsoft's documentation, if the class exposes a public
// member of type XmlSerializerNamespaces decorated with the
// XmlNamespacesDeclarationAttribute, then the XmlSerializer will utilize those
// namespaces during serialization.
public MyTypeWithNamespaces( )
{
this._namespaces = new XmlSerializerNamespaces(new XmlQualifiedName[] {
// Don't do this!! Microsoft's documentation explicitly says it's not supported.
// It doesn't throw any exceptions, but in my testing, it didn't always work.
// new XmlQualifiedName(string.Empty, string.Empty), // And don't do this:
// new XmlQualifiedName("", "")
// DO THIS:
new XmlQualifiedName(string.Empty, "urn:Abracadabra") // Default Namespace
// Add any other namespaces, with prefixes, here.
});
}
// If you have other constructors, make sure to call the default constructor.
public MyTypeWithNamespaces(string label, int epoch) : this( )
{
this._label = label;
this._epoch = epoch;
}
// An element with a declared namespace different than the namespace
// of the enclosing type.
[XmlElement(Namespace="urn:Whoohoo")]
public string Label
{
get { return this._label; }
set { this._label = value; }
}
private string _label;
// An element whose tag will be the same name as the property name.
// Also, this element will inherit the namespace of the enclosing type.
public int Epoch
{
get { return this._epoch; }
set { this._epoch = value; }
}
private int _epoch;
// Per Microsoft's documentation, you can add some public member that
// returns a XmlSerializerNamespaces object. They use a public field,
// but that's sloppy. So I'll use a private backed-field with a public
// getter property. Also, per the documentation, for this to work with
// the XmlSerializer, decorate it with the XmlNamespaceDeclarations
// attribute.
[XmlNamespaceDeclarations]
public XmlSerializerNamespaces Namespaces
{
get { return this._namespaces; }
}
private XmlSerializerNamespaces _namespaces;
}
That's all to this class. Now, some objected to having an XmlSerializerNamespaces
object somewhere within their classes; but as you can see, I neatly tucked it away in the default constructor and exposed a public property to return the namespaces.
Now, when it comes time to serialize the class, you would use the following code:
MyTypeWithNamespaces myType = new MyTypeWithNamespaces("myLabel", 42);
/******
OK, I just figured I could do this to make the code shorter, so I commented out the
below and replaced it with what follows:
// You have to use this constructor in order for the root element to have the right namespaces.
// If you need to do custom serialization of inner objects, you can use a shortened constructor.
XmlSerializer xs = new XmlSerializer(typeof(MyTypeWithNamespaces), new XmlAttributeOverrides(),
new Type[]{}, new XmlRootAttribute("MyTypeWithNamespaces"), "urn:Abracadabra");
******/
XmlSerializer xs = new XmlSerializer(typeof(MyTypeWithNamespaces),
new XmlRootAttribute("MyTypeWithNamespaces") { Namespace="urn:Abracadabra" });
// I'll use a MemoryStream as my backing store.
MemoryStream ms = new MemoryStream();
// This is extra! If you want to change the settings for the XmlSerializer, you have to create
// a separate XmlWriterSettings object and use the XmlTextWriter.Create(...) factory method.
// So, in this case, I want to omit the XML declaration.
XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
xws.Encoding = Encoding.UTF8; // This is probably the default
// You could use the XmlWriterSetting to set indenting and new line options, but the
// XmlTextWriter class has a much easier method to accomplish that.
// The factory method returns a XmlWriter, not a XmlTextWriter, so cast it.
XmlTextWriter xtw = (XmlTextWriter)XmlTextWriter.Create(ms, xws);
// Then we can set our indenting options (this is, of course, optional).
xtw.Formatting = Formatting.Indented;
// Now serialize our object.
xs.Serialize(xtw, myType, myType.Namespaces);
Once you have done this, you should get the following output:
<MyTypeWithNamespaces>
<Label xmlns="urn:Whoohoo">myLabel</Label>
<Epoch>42</Epoch>
</MyTypeWithNamespaces>
I have successfully used this method in a recent project with a deep hierachy of classes that are serialized to XML for web service calls. Microsoft's documentation is not very clear about what to do with the publicly accesible XmlSerializerNamespaces
member once you've created it, and so many think it's useless. But by following their documentation and using it in the manner shown above, you can customize how the XmlSerializer generates XML for your classes without resorting to unsupported behavior or "rolling your own" serialization by implementing IXmlSerializable
.
It is my hope that this answer will put to rest, once and for all, how to get rid of the standard xsi
and xsd
namespaces generated by the XmlSerializer
.
UPDATE: I just want to make sure I answered the OP's question about removing all namespaces. My code above will work for this; let me show you how. Now, in the example above, you really can't get rid of all namespaces (because there are two namespaces in use). Somewhere in your XML document, you're going to need to have something like xmlns="urn:Abracadabra" xmlns:w="urn:Whoohoo
. If the class in the example is part of a larger document, then somewhere above a namespace must be declared for either one of (or both) Abracadbra
and Whoohoo
. If not, then the element in one or both of the namespaces must be decorated with a prefix of some sort (you can't have two default namespaces, right?). So, for this example, Abracadabra
is the default namespace. I could inside my MyTypeWithNamespaces
class add a namespace prefix for the Whoohoo
namespace like so:
public MyTypeWithNamespaces
{
this._namespaces = new XmlSerializerNamespaces(new XmlQualifiedName[] {
new XmlQualifiedName(string.Empty, "urn:Abracadabra"), // Default Namespace
new XmlQualifiedName("w", "urn:Whoohoo")
});
}
Now, in my class definition, I indicated that the <Label/>
element is in the namespace "urn:Whoohoo"
, so I don't need to do anything further. When I now serialize the class using my above serialization code unchanged, this is the output:
<MyTypeWithNamespaces xmlns:w="urn:Whoohoo">
<w:Label>myLabel</w:Label>
<Epoch>42</Epoch>
</MyTypeWithNamespaces>
Because <Label>
is in a different namespace from the rest of the document, it must, in someway, be "decorated" with a namespace. Notice that there are still no xsi
and xsd
namespaces.
This ends my answer to the other question. But I wanted to make sure I answered the OP's question about using no namespaces, as I feel I didn't really address it yet. Assume that <Label>
is part of the same namespace as the rest of the document, in this case urn:Abracadabra
:
<MyTypeWithNamespaces>
<Label>myLabel<Label>
<Epoch>42</Epoch>
</MyTypeWithNamespaces>
Your constructor would look as it would in my very first code example, along with the public property to retrieve the default namespace:
// As noted below, per Microsoft's documentation, if the class exposes a public
// member of type XmlSerializerNamespaces decorated with the
// XmlNamespacesDeclarationAttribute, then the XmlSerializer will utilize those
// namespaces during serialization.
public MyTypeWithNamespaces( )
{
this._namespaces = new XmlSerializerNamespaces(new XmlQualifiedName[] {
new XmlQualifiedName(string.Empty, "urn:Abracadabra") // Default Namespace
});
}
[XmlNamespaceDeclarations]
public XmlSerializerNamespaces Namespaces
{
get { return this._namespaces; }
}
private XmlSerializerNamespaces _namespaces;
Then, later, in your code that uses the MyTypeWithNamespaces
object to serialize it, you would call it as I did above:
MyTypeWithNamespaces myType = new MyTypeWithNamespaces("myLabel", 42);
XmlSerializer xs = new XmlSerializer(typeof(MyTypeWithNamespaces),
new XmlRootAttribute("MyTypeWithNamespaces") { Namespace="urn:Abracadabra" });
...
// Above, you'd setup your XmlTextWriter.
// Now serialize our object.
xs.Serialize(xtw, myType, myType.Namespaces);
And the XmlSerializer
would spit back out the same XML as shown immediately above with no additional namespaces in the output:
<MyTypeWithNamespaces>
<Label>myLabel<Label>
<Epoch>42</Epoch>
</MyTypeWithNamespaces>
First Install pdf2image
pip install pdf2image==1.14.0
Follow the below code for extraction of pages from PDF.
file_path="file path of PDF"
info = pdfinfo_from_path(file_path, userpw=None, poppler_path=None)
maxPages = info["Pages"]
image_counter = 0
if maxPages > 10:
for page in range(1, maxPages, 10):
pages = convert_from_path(file_path, dpi=300, first_page=page,
last_page=min(page+10-1, maxPages))
for page in pages:
page.save(image_path+'/' + str(image_counter) + '.png', 'PNG')
image_counter += 1
else:
pages = convert_from_path(file_path, 300)
for i, j in enumerate(pages):
j.save(image_path+'/' + str(i) + '.png', 'PNG')
Hope it helps coders looking for easy conversion of PDF files to Images as per pages of PDF.
here is my html

<p>
<a id="replaceME" onclick="myFunction2(event)" href="https://www.ccis.edu">I am a student at Columbia College of Missouri.</a>

And so this is how I did something similar in javaScript
var myGlobalNameHolder ="";
function myFunction(){
var myString = prompt("Enter a name", "Name Goes Here");
myGlobalNameHolder = myString;
if (myString != null) {
document.getElementById("replaceME").innerHTML =
"Hello " + myString + ". Welcome to my site";
document.getElementById("belong").innerHTML =
"A place you belong";
}
}
// create a function to pass our event too
function myFunction2(event) {
// variable to make our event short and sweet
var x=window.onbeforeunload;
// logic to make the confirm and alert boxes
if (confirm("Are you sure you want to leave my page?") == true) {
x = alert("Thank you " + myGlobalNameHolder + " for visiting!");
}
}
In this example we will create iPhone class and make exact copy from it by cloning
class iPhone {
public $name;
public $email;
public function __construct($n, $e) {
$this->name = $n;
$this->email = $e;
}
}
$main = new iPhone('Dark', '[email protected]');
$copy = clone $main;
// if you want to print both objects, just write this
echo "<pre>"; print_r($main); echo "</pre>";
echo "<pre>"; print_r($copy); echo "</pre>";
Placing @EdChum's very nice answer into a function count_unique_index
.
The unique method only works on pandas series, not on data frames.
The function below reproduces the behavior of the unique function in R:
unique returns a vector, data frame or array like x but with duplicate elements/rows removed.
And adds a count of the occurrences as requested by the OP.
df1 = pd.DataFrame({'A':['yes','yes','yes','yes','no','no','yes','yes','yes','no'],
'B':['yes','no','no','no','yes','yes','no','yes','yes','no']})
def count_unique_index(df, by):
return df.groupby(by).size().reset_index().rename(columns={0:'count'})
count_unique_index(df1, ['A','B'])
A B count
0 no no 1
1 no yes 2
2 yes no 4
3 yes yes 3
/^[-\w\s]+$/
\w matches letters, digits, and underscores
\s matches spaces, tabs, and line breaks
- matches the hyphen (if you have hyphen in your character set example [a-z], be sure to place the hyphen at the beginning like so [-a-z])
let dict : [String : Any] = ["FirstName" : "Maninder" , "LastName" : "Singh" , "Address" : "Chandigarh"]
dict.forEach { print($0) }
Result would be
("FirstName", "Maninder") ("LastName", "Singh") ("Address", "Chandigarh")
Are you sure you are using Python 3.x? The syntax isn't available in Python 2.x because print
is still a statement.
print("foo" % bar, end=" ")
in Python 2.x is identical to
print ("foo" % bar, end=" ")
or
print "foo" % bar, end=" "
i.e. as a call to print with a tuple as argument.
That's obviously bad syntax (literals don't take keyword arguments). In Python 3.x print
is an actual function, so it takes keyword arguments, too.
The correct idiom in Python 2.x for end=" "
is:
print "foo" % bar,
(note the final comma, this makes it end the line with a space rather than a linebreak)
If you want more control over the output, consider using sys.stdout
directly. This won't do any special magic with the output.
Of course in somewhat recent versions of Python 2.x (2.5 should have it, not sure about 2.4), you can use the __future__
module to enable it in your script file:
from __future__ import print_function
The same goes with unicode_literals
and some other nice things (with_statement
, for example). This won't work in really old versions (i.e. created before the feature was introduced) of Python 2.x, though.

Delete All Records
#for all records
db.session.query(Model).delete()
db.session.commit()
Deleted Single Row
here DB is the object Flask-SQLAlchemy class. It will delete all records from it and if you want to delete specific records then try filter
clause in the query.
ex.
#for specific value
db.session.query(Model).filter(Model.id==123).delete()
db.session.commit()
Delete Single Record by Object
record_obj = db.session.query(Model).filter(Model.id==123).first()
db.session.delete(record_obj)
db.session.commit()

I believe Enterprise Architect can do that.
There are a few things to keep in mind while declaring primitive type values.
They are:
So in your code:
public class Main {
int instanceVariable;
static int staticVariable;
public static void main(String[] args) {
Main mainInstance = new Main()
int localVariable;
int localVariableTwo = 2;
System.out.println(mainInstance.instanceVariable);
System.out.println(staticVariable);
// System.out.println(localVariable); // Will throw a compilation error
System.out.println(localVariableTwo);
}
}
this should work out,
kable(dt) %>%
kable_styling("striped") %>%
add_header_above(c(" " = 1, "Group 1" = 2, "Group 2" = 2, "Group 3" = 2))
#OR
kable(dt) %>%
kable_styling(c("striped", "bordered")) %>%
add_header_above(c(" ", "Group 1" = 2, "Group 2" = 2, "Group 3" = 2)) %>%
add_header_above(c(" ", "Group 4" = 4, "Group 5" = 2)) %>%
add_header_above(c(" ", "Group 6" = 6))

if you're happy using it as a background image and CSS3 then background-size: cover;
would do the trick

@Carlo I really like your implementation of this, but I wanted to share my version and how to use it in my ViewModel
First implement ICommand
public class Command : ICommand
{
public delegate void ICommandOnExecute();
public delegate bool ICommandOnCanExecute();
private ICommandOnExecute _execute;
private ICommandOnCanExecute _canExecute;
public Command(ICommandOnExecute onExecuteMethod, ICommandOnCanExecute onCanExecuteMethod = null)
{
_execute = onExecuteMethod;
_canExecute = onCanExecuteMethod;
}
#region ICommand Members
public event EventHandler CanExecuteChanged
{
add { CommandManager.RequerySuggested += value; }
remove { CommandManager.RequerySuggested -= value; }
}
public bool CanExecute(object parameter)
{
return _canExecute?.Invoke() ?? true;
}
public void Execute(object parameter)
{
_execute?.Invoke();
}
#endregion
}
Notice I have removed the parameter from ICommandOnExecute and ICommandOnCanExecute and added a null to the constructor
Then to use in the ViewModel
public Command CommandToRun_WithCheck
{
get
{
return new Command(() =>
{
// Code to run
}, () =>
{
// Code to check to see if we can run
// Return true or false
});
}
}
public Command CommandToRun_NoCheck
{
get
{
return new Command(() =>
{
// Code to run
});
}
}
I just find this way cleaner as I don't need to assign variables and then instantiate, it all done in one go.
Another reason to the error may be if you are running a cron job that updates a subversion working copy and then has attempted to run a versioned script that was in a conflicted state after the update...
There are 2 major differentiation's between Vector and ArrayList.
Vector is synchronized by default, and ArrayList is not. Note : you can make ArrayList also synchronized by passing arraylist object to Collections.synchronizedList() method. Synchronized means : it can be used with multiple threads with out any side effect.
ArrayLists grow by 50% of the previous size when space is not sufficient for new element, where as Vector will grow by 100% of the previous size when there is no space for new incoming element.
Other than this, there are some practical differences between them, in terms of programming effort:
When to use which one?
Note : even though arraylist grows by 100%, you can avoid this by ensurecapacity() method to make sure that you are allocating sufficient memory at the initial stages itself.
Hope it helps.
They're hints to the compiler to generate the hint prefixes on branches. On x86/x64, they take up one byte, so you'll get at most a one-byte increase for each branch. As for performance, it entirely depends on the application -- in most cases, the branch predictor on the processor will ignore them, these days.
Edit: Forgot about one place they can actually really help with. It can allow the compiler to reorder the control-flow graph to reduce the number of branches taken for the 'likely' path. This can have a marked improvement in loops where you're checking multiple exit cases.
in your selector, you should also specify that you want the checked radiobutton:
$(function(){
$("#submit").click(function(){
alert($('input[name=q12_3]:checked').val());
});
});
There are a couple of ways to solve this. The least hackiest and almost what you want:
$client = new SoapClient(
null,
array(
'location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler',
'uri' => 'http://example.com/wsdl',
'trace' => 1,
'use' => SOAP_LITERAL,
)
);
$params = new \SoapVar("<Acquirer><Id>MyId</Id><UserId>MyUserId</UserId><Password>MyPassword</Password></Acquirer>", XSD_ANYXML);
$result = $client->Echo($params);
This gets you the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://example.com/wsdl">
<SOAP-ENV:Body>
<ns1:Echo>
<Acquirer>
<Id>MyId</Id>
<UserId>MyUserId</UserId>
<Password>MyPassword</Password>
</Acquirer>
</ns1:Echo>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
That is almost exactly what you want, except for the namespace on the method name. I don't know if this is a problem. If so, you can hack it even further. You could put the <Echo>
tag in the XML string by hand and have the SoapClient not set the method by adding 'style' => SOAP_DOCUMENT,
to the options array like this:
$client = new SoapClient(
null,
array(
'location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler',
'uri' => 'http://example.com/wsdl',
'trace' => 1,
'use' => SOAP_LITERAL,
'style' => SOAP_DOCUMENT,
)
);
$params = new \SoapVar("<Echo><Acquirer><Id>MyId</Id><UserId>MyUserId</UserId><Password>MyPassword</Password></Acquirer></Echo>", XSD_ANYXML);
$result = $client->MethodNameIsIgnored($params);
This results in the following request XML:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<Echo>
<Acquirer>
<Id>MyId</Id>
<UserId>MyUserId</UserId>
<Password>MyPassword</Password>
</Acquirer>
</Echo>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Finally, if you want to play around with SoapVar and SoapParam objects, you can find a good reference in this comment in the PHP manual: http://www.php.net/manual/en/soapvar.soapvar.php#104065. If you get that to work, please let me know, I failed miserably.
In order to match the vector lenght and angle with the x,y coordinates of the plot, you can use to following options to plt.quiver:
plt.figure(figsize=(5,2), dpi=100)
plt.quiver(0,0,250,100, angles='xy', scale_units='xy', scale=1)
plt.xlim(0,250)
plt.ylim(0,100)
I had the same problem. When i was trying and testing on a browser on my PC machine i didn't have the "not a function" error, but when i tried on a virtual machine the error was popping. I'd solved it by adding the slick files on my web server and adding the urls of the css and js files from my web server to my html. Before that i was pulling the css and js from CDN.

Thanks to the fantastic answer from Glenn, I used ImageMagik's "mogrify *.png" functionality. However, I had images buried in sub-folders, so I used this simple Python script to apply this to all images in all sub-folders and thought it might help others:
import os
import subprocess
def system_call(args, cwd="."):
print("Running '{}' in '{}'".format(str(args), cwd))
subprocess.call(args, cwd=cwd)
pass
def fix_image_files(root=os.curdir):
for path, dirs, files in os.walk(os.path.abspath(root)):
# sys.stdout.write('.')
for dir in dirs:
system_call("mogrify *.png", "{}".format(os.path.join(path, dir)))
fix_image_files(os.curdir)
Here's one way:
Stream myStream = null;
OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";
if (theDialog.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = theDialog.OpenFile()) != null)
{
using (myStream)
{
// Insert code to read the stream here.
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
Modified from here:MSDN OpenFileDialog.OpenFile
EDIT Here's another way more suited to your needs:

OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";

{
string filename = theDialog.FileName;
string[] filelines = File.ReadAllLines(filename);

{
//check if to move to next employee
if (a != 0 && a % linesPerEmployee == 0)
{
employeeList.Add(employee);
employee = new Employee();
currEmployeeLine = 1;
}
else
{
currEmployeeLine++;
}
switch (currEmployeeLine)
{
case 1:
employee.EmployeeNum = Convert.ToInt32(filelines[a].Trim());
break;
case 2:

The accepted answer works but doesn't move back to previous position if you scroll above it. It is always stuck to the top after being placed there.
$(window).scroll(function(e) {
$el = $('.fixedElement');
if ($(this).scrollTop() > 42 && $el.css('position') != 'fixed') {
$('.fixedElement').css( 'position': 'fixed', 'top': '0px');
} else if ($(this).scrollTop() < 42 && $el.css('position') != 'relative') {
$('.fixedElement').css( 'relative': 'fixed', 'top': '42px');
//this was just my previous position/formating
}
});
jleedev's response whould work, but I wasn't able to get it to work. His example page also didn't work (for me).
The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:
ffmpeg -i input.mov -qscale 0 output.mp4
Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0
):
ffmpeg -i input.mov -q:v 0 output.mp4
This is somewhat tricky since PHP gets evaluated server-side and javascript gets evaluated client side.
I would call your PHP file using an AJAX call from inside javascript and then use JS to insert the returned HTML somewhere on your page.
From the documentation:
As of Beautiful Soup 4.1.2, you can search by CSS class using the keyword argument class_
:
soup.find_all("a", class_="sister")
Which in this case would be:
soup.find_all("div", class_="stylelistrow")
It would also work for:
soup.find_all("div", class_="stylelistrowone stylelistrowtwo")
Not really, in the standard. Some implementations have a nonstandard itoa() function, and you could look up Boost's lexical_cast, but if you stick to the standard it's pretty much a choice between stringstream and sprintf() (snprintf() if you've got it).
I will repeat what the others said, but will just try to make it simpler...
First, just create the Interface class
public interface PostTaskListener<K> {
// K is the type of the result object of the async task
void onPostTask(K result);
}
Second, create the AsyncTask (which can be an inner static class of your activity or fragment) that uses the Interface, by including a concrete class. In the example, the PostTaskListener is parameterized with String, which means it expects a String class as a result of the async task.
public static class LoadData extends AsyncTask<Void, Void, String> {
private PostTaskListener<String> postTaskListener;
protected LoadData(PostTaskListener<String> postTaskListener){
this.postTaskListener = postTaskListener;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (result != null && postTaskListener != null)
postTaskListener.onPostTask(result);
}
}
Finally, the part where your combine your logic. In your activity / fragment, create the PostTaskListener and pass it to the async task. Here is an example:
...
PostTaskListener<String> postTaskListener = new PostTaskListener<String>() {
@Override
public void onPostTask(String result) {
//Your post execution task code
}
}
// Create the async task and pass it the post task listener.
new LoadData(postTaskListener);
Done!
Most Javascript engines do not optimize tail recursion (this might not be an issue if your JSON isn't deeply nested), but I usually err on the side of caution and do iteration instead, e.g.
function traverse(o, fn) {
const stack = [o]
while (stack.length) {
const obj = stack.shift()
Object.keys(obj).forEach((key) => {
fn(key, obj[key], obj)
if (obj[key] instanceof Object) {
stack.unshift(obj[key])
return
}
})
}
}
const o = {
name: 'Max',
legal: false,
other: {
name: 'Maxwell',
nested: {
legal: true
}
}
}
const fx = (key, value, obj) => console.log(key, value)
traverse(o, fx)
i'm not too experienced with open cv but if you want the code in the for loop to be called when a key is pressed, you can use a while loop and an raw_input and a condition to prevent the loop from executing forever
import cv2
camera = cv2.VideoCapture(0)
i = 0
while i < 10:
raw_input('Press Enter to capture')
return_value, image = camera.read()
cv2.imwrite('opencv'+str(i)+'.png', image)
i += 1
del(camera)
You can do this quite easily with lxml. First install it:
[sudo] pip install lxml
Here is a recursive function I wrote that does the heavy lifting for you:
from lxml import objectify as xml_objectify
def xml_to_dict(xml_str):
""" Convert xml to dict, using lxml v3.4.2 xml processing library """
def xml_to_dict_recursion(xml_object):
dict_object = xml_object.__dict__
if not dict_object:
return xml_object
for key, value in dict_object.items():
dict_object[key] = xml_to_dict_recursion(value)
return dict_object
return xml_to_dict_recursion(xml_objectify.fromstring(xml_str))
xml_string = """<?xml version="1.0" encoding="UTF-8"?><Response><NewOrderResp>
<IndustryType>Test</IndustryType><SomeData><SomeNestedData1>1234</SomeNestedData1>
<SomeNestedData2>3455</SomeNestedData2></SomeData></NewOrderResp></Response>"""
print xml_to_dict(xml_string)
The below variant preserves the parent key / element:
def xml_to_dict(xml_str):
""" Convert xml to dict, using lxml v3.4.2 xml processing library, see http://lxml.de/ """
def xml_to_dict_recursion(xml_object):
dict_object = xml_object.__dict__
if not dict_object: # if empty dict returned
return xml_object
for key, value in dict_object.items():
dict_object[key] = xml_to_dict_recursion(value)
return dict_object
xml_obj = objectify.fromstring(xml_str)
return {xml_obj.tag: xml_to_dict_recursion(xml_obj)}
If you want to only return a subtree and convert it to dict, you can use Element.find() to get the subtree and then convert it:
xml_obj.find('.//') # lxml.objectify.ObjectifiedElement instance
See the lxml docs here. I hope this helps!
That's a very general question. One answer is: "it depends what kind of UUID you wish to generate". But a better one is this: "Well, before I answer, can you tell us why you need to code up your own UUID generation algorithm instead of calling the UUID generation functionality that most modern operating systems provide?"
Doing that is easier and safer, and since you probably don't need to generate your own, why bother coding up an implementation? In that case, the answer becomes use whatever your O/S, programming language or framework provides. For example, in Windows, there is CoCreateGuid or UuidCreate or one of the various wrappers available from the numerous frameworks in use. In Linux there is uuid_generate.
If you, for some reason, absolutely need to generate your own, then at least have the good sense to stay away from generating v1 and v2 UUIDs. It's tricky to get those right. Stick, instead, to v3, v4 or v5 UUIDs.
Update:
In a comment, you mention that you are using Python and link to this. Looking through the interface provided, the easiest option for you would be to generate a v4 UUID (that is, one created from random data) by calling uuid.uuid4()
.
If you have some data that you need to (or can) hash to generate a UUID from, then you can use either v3 (which relies on MD5) or v5 (which relies on SHA1). Generating a v3 or v5 UUID is simple: first pick the UUID type you want to generate (you should probably choose v5) and then pick the appropriate namespace and call the function with the data you want to use to generate the UUID from. For example, if you are hashing a URL you would use NAMESPACE_URL
:
uuid.uuid3(uuid.NAMESPACE_URL, 'https://ripple.com')
Please note that this UUID will be different than the v5 UUID for the same URL, which is generated like this:
uuid.uuid5(uuid.NAMESPACE_URL, 'https://ripple.com')
A nice property of v3 and v5 URLs is that they should be interoperable between implementations. In other words, if two different systems are using an implementation that complies with RFC4122, they will (or at least should) both generate the same UUID if all other things are equal (i.e. generating the same version UUID, with the same namespace and the same data). This property can be very helpful in some situations (especially in content-addressible storage scenarios), but perhaps not in your particular case.
If you want to know when use is looking at the fragment you should use
yourFragment.isResumed()
instead of
yourFragment.isVisible()
First of all isVisible()
already checks for isAdded()
so no need for calling both. Second, non-of these two means that user is actually seeing your fragment. Only isResumed()
makes sure that your fragment is in front of the user and user can interact with it if thats whats you are looking for.
Convert.ToInt32(string, base)
does not do base conversion into your base. It assumes that the string contains a valid number in the indicated base, and converts to base 10.
So you're getting an error because "8" is not a valid digit in base 2.
String str = "1111";
String Ans = Convert.ToInt32(str, 2).ToString();
Will show 15
(1111 base 2 = 15 base 10)
String str = "f000";
String Ans = Convert.ToInt32(str, 16).ToString();
Will show 61440
.
Check if there is already a Node server running on your machine and then close it.
If the user cancel the request, the data will be returned as NULL
. The thread will throw a nullPointerException
when you call data.getExtras().get("data");
. I think you just need to add a conditional to check if the data returned is null.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
if (data != null)
{
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
From a ReactJS test, the following code successfully writes a file:
import writeJsonFile from 'write-json-file';
const ans = 42;
writeJsonFile('answer.txt', ans);
const json = {"answer": ans};
writeJsonFile('answer_json.txt', json);
The file is written to the directory containing the tests, so writing to an actual JSON file '*.json' creates a loop!

works like a charm! FYI

The code points used in icon font tricks are usually Private Use code points, which means that they have no generally defined meaning and should not be used in open information interchange, only by private agreement between interested parties. However, Private Use code points can be represented as any other Unicode value, e.g. in CSS using a notation like \f066
, as others have answered. You can even enter the code point as such, if your document is UTF-8 encoded and you know how to type an arbitrary Unicode value by its number in your authoring environment (but of course it would normally be displayed using a symbol for an unknown character).
However, this is not the normal way of using icon fonts. Normally you use a CSS file provided with the font and use constructs like <span class="icon-resize-small">foo</span>
. The CSS code will then take care of inserting the symbol at the start of the element, and you don’t need to know the code point number.
On your backEnd, you should add:
@RequestMapping(value="/blabla", produces="text/plain" , method = RequestMethod.GET)
On the frontEnd (Service):
methodBlabla()
{
const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.get(this.url,{ headers, responseType: 'text'});
}
I implemented some code to do it manually:

WindowsPrincipal principal = new WindowsPrincipal(user);
isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
}
catch (UnauthorizedAccessException ex)
{
isAdmin = false;
}
catch (Exception ex)
{
isAdmin = false;
}
return isAdmin;
}
It happened to me with a node app I was developing on a Debian based distro. First, a simple restart solved it, but it happened again on another app.
Since it's related with the number of watchers that inotify uses to monitors files and look for changes in a directory, you have to set a higher number as limit:
I was able to solve it from the answer posted here (thanks to him!)
So, I ran:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

Sorry for answering what's answered just wanted to give him the link - the site was really useful to me all the time dealing with C.
Question is a little vague.
list_of_lines = multiple_lines.split("\n")
for line in list_of_lines:
list_of_items_in_line = line.split(",")
first_int = int(list_of_items_in_line[0])
etc.
Assume that the source file you want to compile is main.cpp and your example_dll.dll and example_dll.lib . now run cl.exe main.cpp /EHsc /link example_dll.lib
now you may get main.exe
A length restriction on a parameter list is just one more restriction. And restriction means applied violence. It sounds funny, but you can be non-violent even when programming. Just let the code dictate the rules. It is obvious that if you have many parameters, the body of the function/class method will be big enough to make use of them. And big code snippets usually can be refactored and split into smaller chunks. So you get solution against having many parameters as free bonus, since they are split among the smaller refactored pieces of code.
If you are using Spring, there is CustomizableThreadFactory
for which you can set a thread name prefix.
Example:
ExecutorService alphaExecutor =
Executors.newFixedThreadPool(10, new CustomizableThreadFactory("alpha-"));
Alternatively, you can create your ExecutorService
as a Spring bean using ThreadPoolExecutorFactoryBean
- then the threads will all be named with the beanName-
prefix.
@Bean
public ThreadPoolExecutorFactoryBean myExecutor() {
ThreadPoolExecutorFactoryBean executorFactoryBean = new ThreadPoolExecutorFactoryBean();
// configuration of your choice
return executorFactoryBean;
}
In the example above, the threads will be named with myExecutor-
prefix. You can set the prefix explicitly to a different value (eg. "myPool-"
) by setting executorFactoryBean.setThreadNamePrefix("myPool-")
on the factory bean.
public static void main(String[] args) {
char[] array = "aabsbdcbdgratsbdbcfdgs".toCharArray();

int lastIndex = 0;
for (char c : array) {
int foundIndex = -1;
for (int i = 0; i < lastIndex; i++) {
if (countArr[i][0] == c) {
foundIndex = i;
break;
}
}
if (foundIndex >= 0) {
int a = countArr[foundIndex][1];
countArr[foundIndex][1] = (char) ++a;
} else {
countArr[lastIndex][0] = c;
countArr[lastIndex][1] = '1';
lastIndex++;
}
}
for (int i = 0; i < lastIndex; i++) {
System.out.println(countArr[i][0] + " " + countArr[i][1]);
}
}
To install Python package from github, you need to clone that repository.
git clone https://github.com/jkbr/httpie.git
Then just run the setup.py file from that directory,
sudo python setup.py install
Put in your CD or mount your ISO. Run the setup program from the command prompt using the flags /uninstall /force

It looks like the best way to explain is that tags act as read only branches. You can use a branch as a tag, but you may inadvertently update it with new commits. Tags are guaranteed to point to the same commit as long as they exist.

If you use array_merge
, this will reindex the keys. The manual states:
Values in the input array with numeric keys will be renumbered with incrementing keys starting from zero in the result array.

This is where i found the original answer.

Your tables should have as immediate children just tbody
and thead
elements, with the rows within*. So, amend the HTML to be:
<table border="1" width="100%" id="test">
<tbody>
<tr>
<td>
<table border="1" width="100%">
<tbody>
<tr>
<td>table 2</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr><td>table 1</td></tr>
<tr><td>table 1</td></tr>
<tr><td>table 1</td></tr>
</tbody>
</table>
Then amend your selector slightly to this:
#test > tbody > tr:last-child { background:#ff0000; }
See it in action here. That makes use of the child selector, which:
...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.
So, you are targeting only direct children of tbody
elements that are themselves direct children of your #test
table.
The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:
#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }
* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:
...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.
If you use Robert Harder's Base64 utility, then you can do:
InputStream is = new Base64.InputStream(cph);
Or with sun's JRE, you can do:
InputStream is = new
com.sun.xml.internal.messaging.saaj.packaging.mime.util.BASE64DecoderStream(cph)
However don't rely on that class continuing to be a part of the JRE, or even continuing to do what it seems to do today. Sun say not to use it.
There are other Stack Overflow questions about Base64 decoding, such as this one.
Yes, you can do almost that:

The ps command (at least the procps version used by many Linux distributions) has a number of format fields that relate to the process start time, including lstart
which always gives the full date and time the process started:
# ps -p 1 -wo pid,lstart,cmd
PID STARTED CMD
1 Mon Dec 23 00:31:43 2013 /sbin/init
# ps -p 1 -p $$ -wo user,pid,%cpu,%mem,vsz,rss,tty,stat,lstart,cmd
USER PID %CPU %MEM VSZ RSS TT STAT STARTED CMD
root 1 0.0 0.1 2800 1152 ? Ss Mon Dec 23 00:31:44 2013 /sbin/init
root 5151 0.3 0.1 4732 1980 pts/2 S Sat Mar 8 16:50:47 2014 bash
For a discussion of how the information is published in the /proc filesystem, see https://unix.stackexchange.com/questions/7870/how-to-check-how-long-a-process-has-been-running
(In my experience under Linux, the time stamp on the /proc/ directories seem to be related to a moment when the virtual directory was recently accessed rather than the start time of the processes:
# date; ls -ld /proc/1 /proc/$$

dr-xr-xr-x 7 root root 0 2014-03-08 16:51 /proc/5151
Note that in this case I ran a "ps -p 1" command at about 16:50, then spawned a new bash shell, then ran the "ps -p 1 -p $$" command within that shell shortly afterward....)
Here's a tidyverse version:
library(tidyverse)
data(diamonds)
(as.data.frame(table(diamonds$cut)) %>% rename(Count=1,Freq=2) %>% mutate(Perc=100*Freq/sum(Freq)))
Or if you want a handy function:
getPercentages <- function(df, colName) {
df.cnt <- df %>% select({{colName}}) %>%
table() %>%
as.data.frame() %>%
rename({{colName}} :=1, Freq=2) %>%
mutate(Perc=100*Freq/sum(Freq))
}
Now you can do:
diamonds %>% getPercentages(cut)
or this:
df=diamonds %>% group_by(cut) %>% group_modify(~.x %>% getPercentages(clarity))
ggplot(df,aes(x=clarity,y=Perc))+geom_col()+facet_wrap(~cut)
I always write a default method "findByIdOrError" in widely used CrudRepository repos/interfaces.
@Repository
public interface RequestRepository extends CrudRepository<Request, Integer> {
default Request findByIdOrError(Integer id) {
return findById(id).orElseThrow(EntityNotFoundException::new);
}
}
text.indexOf("newString")
is the best method instead of startsWith
.
Example:
var text = "Format";
if(text.indexOf("Format") == 0) {
alert(text + " = Format");
} else {
alert(text + " != Format");
}
@Gadde - your answer was very helpful. Thank you! I needed a "Maps"-like zoom for a div and was able to produce the feel I needed with your post. My criteria included the need to have the click repeat and continue to zoom out/in with each click. Below is my final result.
var currentZoom = 1.0;
$(document).ready(function () {
$('#btn_ZoomIn').click(
function () {
$('#divName').animate({ 'zoom': currentZoom += .1 }, 'slow');
})
$('#btn_ZoomOut').click(
function () {
$('#divName').animate({ 'zoom': currentZoom -= .1 }, 'slow');
})
$('#btn_ZoomReset').click(
function () {
currentZoom = 1.0
$('#divName').animate({ 'zoom': 1 }, 'slow');
})
});
You just need this:
$(".hidden").attr("placeholder", "Type here to search");
classList
is used for manipulating classes and not attributes.
Following on from my comment to the answer @bobby posted, here is the code I would use:
function parseQuery(str)
{
if(typeof str != "string" || str.length == 0) return {};
var s = str.split("&");
var s_length = s.length;
var bit, query = {}, first, second;
for(var i = 0; i < s_length; i++)
{
bit = s[i].split("=");
first = decodeURIComponent(bit[0]);
if(first.length == 0) continue;
second = decodeURIComponent(bit[1]);
if(typeof query[first] == "undefined") query[first] = second;
else if(query[first] instanceof Array) query[first].push(second);
else query[first] = [query[first], second];
}
return query;
}
This code takes in the querystring provided (as 'str') and returns an object. The string is split on all occurances of &, resulting in an array. the array is then travsersed and each item in it is split by "=". This results in sub arrays wherein the 0th element is the parameter and the 1st element is the value (or undefined if no = sign). These are mapped to object properties, so for example the string "hello=1&another=2&something" is turned into:
{
hello: "1",
another: "2",
something: undefined
}
In addition, this code notices repeating reoccurances such as "hello=1&hello=2" and converts the result into an array, eg:
{
hello: ["1", "2"]
}
You'll also notice it deals with cases in whih the = sign is not used. It also ignores if there is an equal sign straight after an & symbol.
A bit overkill for the original question, but a reusable solution if you ever need to work with querystrings in javascript :)
In addition to how Java defines static inner classes, there is another definition of static classes as per the C# world [1]. A static class is one that has only static methods (functions) and it is meant to support procedural programming. Such classes aren't really classes in that the user of the class is only interested in the helper functions and not in creating instances of the class. While static classes are supported in C#, no such direct support exists in Java. You can however use enums to mimic C# static classes in Java so that a user can never create instances of a given class (even using reflection) [2]:
public enum StaticClass2 {
// Empty enum trick to avoid instance creation
; // this semi-colon is important
public static boolean isEmpty(final String s) {
return s == null || s.isEmpty();
}
}
- (void)viewDidLoad
{
[self.tableView setSeparatorColor:[UIColor myColor]];
}
I hope that helps - you'll need the self.
to access it, remember.
Swift 4.2
tableView.separatorColor = UIColor.red
You can make a default constraint on this column that will put a default getdate() as a value.
Example:
alter table dbo.TABLE
add constraint df_TABLE_DATE default getdate() for DATE_COLUMN
A list comprehension is a simple approach:
j2 = [x for x in j if x >= 5]
Alternately, you can use filter
for the exact same result:
j2 = filter(lambda x: x >= 5, j)
Note that the original list j
is unmodified.
You can achieve that effect using a combination of CSS linear-gradient and mix-blend-mode.

CSS

bottom: 0;
background: linear-gradient(45deg, red, orange, yellow, green, blue, purple);

}
What this does is add a linear gradient on the paragraph's ::after
pseudo-element and make it cover the whole paragraph element. But with mix-blend-mode: screen
, the gradient will only show on parts where there is text.
Here's a jsfiddle to show this at work. Just modify the linear-gradient
values to achieve what you want.
Remove a list’s bullets and apply some light margin with a combination of two classes, .list-inline and .list-inline-item.
<ul class="list-inline">

<li class="list-inline-item"><a class="social-icon text-xs-center" target="_blank" href="#">G+</a></li>
<li class="list-inline-item"><a class="social-icon text-xs-center" target="_blank" href="#">T</a></li>
</ul>
Things seems a little confused in the code in your question, so I am going to give you an example of what I think you are try to do.
First considerations are about mixing HTML, Javascript and CSS:
Why is using onClick() in HTML a bad practice?
I will be removing inline content and splitting these into their appropriate files.
Next, I am going to go with the "click" event and displose of the "change" event, as it is not clear that you want or need both.
Your function changeBackground
sets both the backround color and the text color to the same value (your text will not be seen), so I am caching the color value as we don't need to look it up in the DOM twice.
CSS
#TheForm {
margin-left: 396px;
}
#submitColor {
margin-left: 48px;
margin-top: 5px;
}
HTML
<form id="TheForm">
<input id="color" type="text" />
<br/>
<input id="submitColor" value="Submit" type="button" />
</form>
<span id="coltext">This text should have the same color as you put in the text box</span>
Javascript
function changeBackground() {
var color = document.getElementById("color").value; // cached
// The working function for changing background color.
document.bgColor = color;
// The code I'd like to use for changing the text simultaneously - however it does not work.
document.getElementById("coltext").style.color = color;
}
document.getElementById("submitColor").addEventListener("click", changeBackground, false);

CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).
Hex values are written as 3 double digit numbers, starting with a # sign.
Update: as pointed out by @Ian
Hex can be either 3 or 6 characters long
Source: W3C
The format of an RGB value in hexadecimal notation is a ‘#’ immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.
Here is an alternative function that will check that your input is a valid CSS Hex Color, it will set the text color only or throw an alert if it is not valid.
For regex testing, I will use this pattern
/^#(?:[0-9a-f]{3}){1,2}$/i
but if you were regex matching and wanted to break the numbers into groups then you would require a different pattern
function changeBackground() {
var color = document.getElementById("color").value.trim(),
rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i;
if (rxValidHex.test(color)) {
document.getElementById("coltext").style.color = color;
} else {
alert("Invalid CSS Hex Color");
}
}
document.getElementById("submitColor").addEventListener("click", changeBackground, false);
On jsfiddle
Here is a further modification that will allow colours by name along with by hex.
function changeBackground() {
var names = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "Darkorange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Grey", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGrey", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"],

You can use the Linux based syntax in one of your startup scripts. Just tested this on an OS X Mountain Lion box.
eg. in your ~/.bash_profile
export TERM="xterm-color"
export PS1='\[\e[0;33m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '
This gives you a nice colored prompt. To add the colored ls
output, you can add alias ls="ls -G"
.
To test, just run a source ~/.bash_profile
to update your current terminal.
Side note about the colors:
The colors are preceded by an escape sequence \e
and defined by a color value, composed of [style;color+m]
and wrapped in an escaped []
sequence.
eg.
\[\e[0;31m\]
\[\e[1;31m\]
\[\e[0m\]
I always add a slightly modified color-scheme in the root's .bash_profile to make the username red, so I always see clearly if I'm logged in as root (handy to avoid mistakes if I have many terminal windows open).
In /root/.bash_profile
:
PS1='\[\e[0;31m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '
For all my SSH accounts online I make sure to put the hostname in red, to distinguish if I'm in a local or remote terminal. Just edit the .bash_profile
file in your home dir on the server.. If there is no .bash_profile
file on the server, you can create it and it should be sourced upon login.
If this is not working as expected for you, please read some of the comments below since I'm not using MacOS very often..
If you want to do this on a remote server, check if the ~/.bash_profile
file exists. If not, simply create it and it should be automatically sourced upon your next login.
A slight change to Thangamani Palanisamy answer, which allows the Binary reader to be disposed and corrects the input length issue in his comments.
string result = string.Empty;
using (BinaryReader b = new BinaryReader(file.InputStream))
{
byte[] binData = b.ReadBytes(file.ContentLength);
result = System.Text.Encoding.UTF8.GetString(binData);
}
I had the same problem. I used a trigger and in that trigger I called a procedure which computed some values into 2 OUT variables. When I tried to print the result in the trigger body, nothing showed on screen. But then I solved this problem by making 2 local variables in a function, computed what I need with them and finally, copied those variables in your OUT procedure variables. I hope it'll be useful and successful!
To remove a timezone (tzinfo) from a datetime object:
# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)
If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.
# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)
Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime
object to insert into the database. The solution is to convert your datetime.datetime
object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime
objects where one is timezone aware and another is timezone naive.

# MySQL example! where MySQL doesn't support timezones with its DATETIME type!

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
arrowDt = arrowObj.to("utc").datetime
# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)
# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()
# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3
# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

I actually just wrote my own script for this purpose. It doesn't use Xcode. (It's based off a similar script in the Gambit Scheme project.)
Basically, it runs ./configure and make three times (for i386, armv7, and armv7s), and combines each of the resulting libraries into a fat lib.
i have alreay 2 situations where directives and services/factories didnt play well.
the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).
in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.
i even tried to make a directive with a controller and an isolated-scope
only when i moved everything to a controller and it worked like magic.

states.split()
will return

If you need one random from them, then you have to use the random
module:
import random
states = "... ..."
random_state = random.choice(states.split())
simple solution:
public class long_length {
long x,l=1,n;

if (x/n!=0){
l++;
}
}
System.out.print(l);

A char is a value type, so its value cannot be null. (Unless it is wrapped in a Nullable container).
Since it can't be null, in contains some numeric code and each code is mapped to some character.

Reason for error:
The query from p in dc.BlogPosts where p.BlogPostID == ID select p
returns a sequence.
Single()
tries to retrieve an element from the sequence returned in step1.
As per the exception - The sequence returned in step1 contains no elements.
Single() tries to retrieve an element from the sequence returned in step1 which contains no elements.
Since Single()
is not able to fetch a single element from the sequence returned in step1, it throws an error.
Fix:
Make sure the query (from p in dc.BlogPosts where p.BlogPostID == ID select p)
returns a sequence with at least one element.

insert
is not a recommended way - it is one of the ways to insert into map. The difference with operator[]
is that the insert
can tell whether the element is inserted into the map. Also, if your class has no default constructor, you are forced to use insert
. operator[]
needs the default constructor because the map checks if the element exists. If it doesn't then it creates one using default constructor and returns a reference (or const reference to it).Because map containers do not allow for duplicate key values, the insertion operation checks for each element inserted whether another element exists already in the container with the same key value, if so, the element is not inserted and its mapped value is not changed in any way.

How about this?
LinkedHashSet<Integer> test = new LinkedHashSet<Integer>();
Random random = new Random();
do{
test.add(random.nextInt(1000) + 1);
}while(test.size() != 1000);
The user can then iterate through the Set
using a for loop.
Your problem is that you are NOT testing the length of the array until it is too late.
But I just want to point out that the way to solve this problem is to READ THE STACK TRACE.
The exception message will clearly tell you are trying to create an array with length -1, and the trace will tell you exactly which line of your code is doing this. The rest is simple logic ... working back to why the length you are using is -1.
These are the necersary imports:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
And this is a method that will allow you to read from a File by passing it the filename as a parameter like this: readFile("yourFile.txt");
String readFile(String fileName) throws IOException {
BufferedReader br = new BufferedReader(new FileReader(fileName));
try {
StringBuilder sb = new StringBuilder();
String line = br.readLine();
while (line != null) {
sb.append(line);
sb.append("\n");
line = br.readLine();
}
return sb.toString();
} finally {
br.close();
}
}
You can use from root directory:
RewriteEngine On
RewriteRule ^(?:system)\b.* /403.html
Or:
RewriteRule ^(?:system)\b.* /403.php # with header('HTTP/1.0 403 Forbidden');
In your example number
is a primitive, so will be stored as a value.
If you want to use a reference then you should use one of the wrapper types (e.g. Integer
)
if you are in the windows7 platform maybe you should change the NODE_PATH like this:
%AppData%\npm\node_modules
Also, spark is a nice little bar graph in your shell.
Use the Reformat and Compile plugin (inspired by the Save Actions plugin of Alexandre DuBreuil):
https://plugins.jetbrains.com/plugin/8231?pr=idea_ce
At the moment I am only offering a jar file, but this is the most important part of the code:
private final static Set<Document> documentsToProcess = new HashSet<Document>();
private static VirtualFile[] fileToCompile = VirtualFile.EMPTY_ARRAY;
// The plugin extends FileDocumentManagerAdapter.
// beforeDocumentSaving calls reformatAndCompile
private static void reformatAndCompile(
@NotNull final Project project,
@NotNull final Document document,
@NotNull final PsiFile psiFile) {
documentsToProcess.add(document);
if (storage.isEnabled(Action.compileFile) && isDocumentActive(project, document)) {
fileToCompile = isFileCompilable(project, psiFile.getVirtualFile());
}
ApplicationManager.getApplication().invokeLater(new Runnable() {
@Override
public void run() {
if (documentsToProcess.contains(document)) {
documentsToProcess.remove(document);
if (storage.isEnabled(Action.optimizeImports)
|| storage.isEnabled(Action.reformatCode)) {
CommandProcessor.getInstance().runUndoTransparentAction(new Runnable() {
@Override
public void run() {
if (storage.isEnabled(Action.optimizeImports)) {
new OptimizeImportsProcessor(project, psiFile)
.run();
}
if (storage.isEnabled(Action.reformatCode)) {
new ReformatCodeProcessor(
project,
psiFile,
null,
ChangeListManager
.getInstance(project)
.getChange(psiFile.getVirtualFile()) != null)
.run();
}
ApplicationManager.getApplication().runWriteAction(new Runnable() {
@Override
public void run() {
CodeInsightUtilCore.forcePsiPostprocessAndRestoreElement(psiFile);
}
});
}
});
}
}
if (fileToCompile.length > 0) {
if (documentsToProcess.isEmpty()) {
compileFile(project, fileToCompile);
fileToCompile = VirtualFile.EMPTY_ARRAY;
}
} else if (storage.isEnabled(Action.makeProject)) {
if (documentsToProcess.isEmpty()) {
makeProject(project);
}
} else {
saveFile(project, document, psiFile.getVirtualFile());
}
}
}, project.getDisposed());
}
private static void makeProject(@NotNull final Project project) {
ApplicationManager.getApplication().invokeLater(new Runnable() {
@Override
public void run() {
CompilerManager.getInstance(project).make(null);
}
}, project.getDisposed());
}
private static void compileFile(
@NotNull final Project project,
@NotNull final VirtualFile[] files) {
ApplicationManager.getApplication().invokeLater(new Runnable() {

if (fileDocumentManager.isFileModified(file)) {
fileDocumentManager.saveDocument(document);
}
}
}, project.getDisposed());
}
I had to combine Maiasaura and Svun answers to get it to work: using setwd and escaping all the slashes and spaces.
setwd('C:\\Users\\firstname\ lastname\\Desktop\\folder1\\folder2\\folder3')
data = read.csv("file.csv")
data
This solved the issue for me.
(The typical method would be to use plot
just once to set up the limits, possibly to include the range of all series combined, and then to use points
and lines
to add the separate series.) To use plot
multiple times with par(new=TRUE)
you need to make sure that your first plot has a proper ylim
to accept the all series (and in another situation, you may need to also use the same strategy for xlim):
# first plot
plot(x, y1, ylim=range(c(y1,y2)))
# second plot EDIT: needs to have same ylim
par(new = TRUE)
plot(x, y2, ylim=range(c(y1,y2)), axes = FALSE, xlab = "", ylab = "")
This next code will do the task more compactly, by default you get numbers as points but the second one gives you typical R-type-"points":
matplot(x, cbind(y1,y2))
matplot(x, cbind(y1,y2), pch=1)
As Others have mentioned, add these refernces to visual studios with Copy Local
set to true
. ( I also had to add System.Web.Webpages
)
Microsoft.Web.Infrastructure
System.Web.Razor
System.Web.WebPages.Deployment
System.Web.WebPages.Razor
System.Web.Webpages
If you installed the command line tools separately, delete them using:
sudo rm -rf /Library/Developer/CommandLineTools
function selectText(containerid) {_x000D_
if (document.selection) { // IE_x000D_
var range = document.body.createTextRange();_x000D_
range.moveToElementText(document.getElementById(containerid));_x000D_
range.select();_x000D_
} else if (window.getSelection) {_x000D_
var range = document.createRange();_x000D_
range.selectNode(document.getElementById(containerid));_x000D_
window.getSelection().removeAllRanges();_x000D_
window.getSelection().addRange(range);_x000D_
}_x000D_
}
_x000D_
<div id="selectable" onclick="selectText('selectable')">http://example.com/page.htm</div>
_x000D_
Now you have to pass the ID as an argument, which in this case is "selectable", but it's more global, allowing you to use it anywhere multiple times without using, as chiborg mentioned, jQuery.
The axes class has a set_yticklabels function which allows you to set the tick labels, like so:
#ax is the axes instance
group_labels = ['control', 'cold treatment',
'hot treatment', 'another treatment',
'the last one']
ax.set_xticklabels(group_labels)
I'm still working on why your example above didn't work.
I never had to use this before until today. Its because in my code I am using multi-threadding and the multi-threading API I am using is the windows one (_beginthreadex).
To start the thread:
_beginthreadex(NULL, 0, ExecuteCommand, currCommand, 0, 0);
The ExecuteCommand function MUST use the __stdcall keyword in the method signature in order for beginthreadex to call it:
unsigned int __stdcall Scene::ExecuteCommand(void* command)
{
return system(static_cast<char*>(command));
}
I'm using ReactJs and used import 'core-js/es6/string';
at the start of index.js
to solve my problem.
I'm also using import 'react-app-polyfill/ie11';
to support running React in IE11.
react-app-polyfill
This package includes polyfills for various browsers. It includes minimum requirements and commonly used language features used by Create React App projects.
https://github.com/facebook/create-react-app/blob/master/packages/react-app-polyfill/README.md
Based on @ChadBefus 's answer and @shmosel comment, I'd recommend using this. (Efficient lookup, and works on pure java >= 8)
import java.util.stream.Collectors;
import java.util.function.Function;
import java.util.Map;
import java.util.Arrays;
public enum MyEnum {
OPTION_1(-66),
OPTION_2(32);
private int value;
private MyEnum(final int value) {
this.value = value;
}
public int getValue() {
return this.value;
}
private static Map<Integer, MyEnum> reverseLookup =
Arrays.stream(MyEnum.values()).collect(Collectors.toMap(MyEnum::getValue, Function.identity()));
public static MyEnum fromInt(final int id) {
return reverseLookup.getOrDefault(id, OPTION_1);
}
public static void main(String[] args) {
System.out.println(fromInt(-66).toString());
}
}
You can directly go to Web IDE and upload your folder there.
Steps:
In some cases you may not be able to directly upload entire folder containing folders, In such cases, you will have to create directory structure yourself.
You will have to use JavaScript. The browser will only send the value
of the selected option (so its not PHP's fault).
What your JS should do is hook into the form's submit event and create a hidden field with the value of the selected option's stud_name
value. This hidden field will then get sent to the server.
That being said ... you shouldn't relay on the client to provide the correct data. You already know what stud_name
should be for a given value on the server (since you are outputting it). So just apply the same logic when you are processing the form.
Make sure you include the = sign in addition to passing the arguments to the function. I.E.
=SUM(A1:A3) //this would give you the sum of cells A1, A2, and A3.
I recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.
IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.
check out the documentation and the demo.
keystore simply stores private keys, wheras truststore stores public keys. You will want to generate a java certificate for SSL communication. You can use a keygen command in windows, this will probably be the most easy solution.
This is an addendum to @endy-tjahjono's solution.
I ended up not being able to get the value of uploadme from the scope. Even though uploadme in the HTML was visibly updated by the directive, I could still not access its value by $scope.uploadme. I was able to set its value from the scope, though. Mysterious, right..?
As it turned out, a child scope was created by the directive, and the child scope had its own uploadme.
The solution was to use an object rather than a primitive to hold the value of uploadme.
In the controller I have:
$scope.uploadme = {};
$scope.uploadme.src = "";
and in the HTML:
<input type="file" fileread="uploadme.src"/>
<input type="text" ng-model="uploadme.src"/>
There are no changes to the directive.
Now, it all works like expected. I can grab the value of uploadme.src from my controller using $scope.uploadme.
Maybe something like this:
import matplotlib.pyplot
import pylab
x = [1,2,3,4]
y = [3,4,8,6]
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
EDIT:
Let me see if I understand you correctly now:
You have:
test1 | test2 | test3
test3 | 1 | 0 | 1
test4 | 0 | 1 | 0
test5 | 1 | 1 | 0
Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.
Let's say you results are stored in a 2-D list:
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
We want to transform them into two variables so we are able to plot them.
And I believe this code will give you what you are looking for:
import matplotlib
import pylab
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
x = []
y = []
for ind_1, sublist in enumerate(results):
for ind_2, ele in enumerate(sublist):
if ele == 1:
x.append(ind_1)
y.append(ind_2)
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
Notice that I do need to import pylab
, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.
Use:
File.ReadAllLines("My textfile.txt");
Reference: https://msdn.microsoft.com/pt-br/library/s2tte0y1(v=vs.110).aspx
The Y
array in your screenshot is not a 1D array, it's a 2D array with 300 rows and 1 column, as indicated by its shape
being (300, 1)
.
To remove the extra dimension, you can slice the array as Y[:, 0]
. To generally convert an n-dimensional array to 1D, you can use np.reshape(a, a.size)
.
Another option for converting a 2D array into 1D is flatten()
function from numpy.ndarray
module, with the difference that it makes a copy of the array.
Probably the best reason is because 0xfffffffffffffff/15
would give you a horribly wrong answer...
If you have sklearn isntalled, a simple alternative is to use sklearn.metrics.auc
This computes the area under the curve using the trapezoidal rule given arbitrary x, and y array
import numpy as np
from sklearn.metrics import auc
dx = 5
xx = np.arange(1,100,dx)
yy = np.arange(1,100,dx)
print('computed AUC using sklearn.metrics.auc: {}'.format(auc(xx,yy)))
print('computed AUC using np.trapz: {}'.format(np.trapz(yy, dx = dx)))
both output the same area: 4607.5
the advantage of sklearn.metrics.auc is that it can accept arbitrarily-spaced 'x' array, just make sure it is ascending otherwise the results will be incorrect
