HTTP 2.0 is a binary protocol that multiplexes numerous streams going over a single (normally TLS-encrypted) TCP connection.
The contents of each stream are HTTP 1.1 requests and responses, just encoded and packed up differently. HTTP2 adds a number of features to manage the streams, but leaves old semantics untouched.
This might work:
mkdir {{FOLDER NAME}}
cd {{FOLDER NAME}}
touch {{FOLDER NAME}}/file.txt
Some of the other answers return an actual string whereas I had more need to know the actual index int. And the answers that do that seem to over-complicate things. Using some of the other answers as inspiration, I did the following...
First, I created a function:
CREATE FUNCTION [dbo].[LastIndexOf] (@stringToFind varchar(max), @stringToSearch varchar(max))
RETURNS INT
AS
BEGIN
RETURN (LEN(@stringToSearch) - CHARINDEX(@stringToFind,REVERSE(@stringToSearch))) + 1
END
GO
Then, in your query you can simply do this:
declare @stringToSearch varchar(max) = 'SomeText: SomeMoreText: SomeLastText'
select dbo.LastIndexOf(':', @stringToSearch)
The above should return 23 (the last index of ':')
Hope this made it a little easier for someone!

I found the same issue with Tomcat version 6.026.
I used the Mysql JDBC.jar in WebAPP Library as well as in TOMCAT Lib.
To fix the above by removing the Jar from the TOMCAT lib folder.
So what I understand is that TOMCAT is handling the JDBC memory leak properly. But if the MYSQL Jdbc jar is duplicated in WebApp and Tomcat Lib, Tomcat will only be able to handle the jar present in the Tomcat Lib folder.
I managed to use a one-line Ruby script for that purpose (although it had to go in a separate file). First, run these commands once on each client machine you'll be pushing docs from:
gem install github-markup
gem install commonmarker
Next, install this script in your client image, and call it render-readme-for-javadoc.rb
:
require 'github/markup'
puts GitHub::Markup.render_s(GitHub::Markups::MARKUP_MARKDOWN, File.read('README.md'))
Finally, invoke it like this:
ruby ./render-readme-for-javadoc.rb >> project/src/main/javadoc/overview.html
ETA: This won't help you with StackOverflow-flavor Markdown, which seems to be failing on this answer.
Personally I'd go with AJAX.

helpers, I suggest you to add a couple of properties in your model
public bool TriggerOnLoad { get; set; }
public string TriggerOnLoadMessage { get; set: }
Change your view to a strongly typed Model via
@using MyModel
Before returning the View, in case of successfull creation do something like
MyModel model = new MyModel();
model.TriggerOnLoad = true;
model.TriggerOnLoadMessage = "Object successfully created!";
return View ("Add", model);
then in your view, add this
@{
if (model.TriggerOnLoad) {
<text>
<script type="text/javascript">
alert('@Model.TriggerOnLoadMessage');
</script>
</text>
}
}
Of course inside the tag you can choose to do anything you want, event declare a jQuery ready function:
$(document).ready(function () {
alert('@Model.TriggerOnLoadMessage');
});
Please remember to reset the Model properties upon successfully alert emission.
Another nice thing about MVC is that you can actually define an EditorTemplate for all this, and then use it in your view via:
@Html.EditorFor (m => m.TriggerOnLoadMessage)
But in case you want to build up such a thing, maybe it's better to define your own C# class:
class ClientMessageNotification {
public bool TriggerOnLoad { get; set; }
public string TriggerOnLoadMessage { get; set: }
}
and add a ClientMessageNotification
property in your model. Then write EditorTemplate / DisplayTemplate for the ClientMessageNotification
class and you're done. Nice, clean, and reusable.

Assuming you have two programs that process the two files, process_in.exe and process_out.exe:
for %%f in (*.in) do (
echo %%~nf
process_in "%%~nf.in"
process_out "%%~nf.out"
)
%%~nf is a substitution modifier, that expands %f to a file name only. See other modifiers in https://technet.microsoft.com/en-us/library/bb490909.aspx (midway down the page) or just in the next answer.
You can try MIMEText
msg = MIMEText('text')
msg['to'] =
msg['cc'] =
then send msg.as_string()

card = random.choice(cards)
cardsLeft = cards.replace(card, '', 1)
How to remove one character from a string: Here is an example where there is a stack of cards represented as characters in a string. One of them is drawn (import random module for the random.choice() function, that picks a random character in the string). A new string, cardsLeft, is created to hold the remaining cards given by the string function replace() where the last parameter indicates that only one "card" is to be replaced by the empty string...
I like using _.pickBy, because you have full control over what you are removing:
var person = {"name":"bill","age":21,"sex":undefined,"height":null};
var cleanPerson = _.pickBy(person, function(value, key) {
return !(value === undefined || value === null);
});
Source: https://www.codegrepper.com/?search_term=lodash+remove+undefined+values+from+object
in Eike Thies's response above, if we use underscore.js, filter could be simplified to :
var app = angular.module('myApp', []).filter('object2Array', function() {
return function(input) {
return _.toArray(input);
}
});
ClassNotFoundException and NoClassDefFoundError occur when a particular class is not found at runtime.However, they occur at different scenarios.
ClassNotFoundException is an exception that occurs when you try to load a class at run time using Class.forName() or loadClass() methods and mentioned classes are not found in the classpath.
public class MainClass
{
public static void main(String[] args)
{
try
{
Class.forName("oracle.jdbc.driver.OracleDriver");
}catch (ClassNotFoundException e)
{
e.printStackTrace();
}
}
}
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)
at pack1.MainClass.main(MainClass.java:17)
NoClassDefFoundError is an error that occurs when a particular class is present at compile time, but was missing at run time.
class A
{
// some code
}
public class B
{
public static void main(String[] args)
{
A a = new A();
}
}
When you compile the above program, two .class files will be generated. One is A.class and another one is B.class. If you remove the A.class file and run the B.class file, Java Runtime System will throw NoClassDefFoundError like below:
Exception in thread "main" java.lang.NoClassDefFoundError: A

You cannot style a variable such as $ip['countryName']
You can only style elements like p,div, etc, or classes and ids.
If you want to style $ip['countryName'] there are several ways.
You can echo it within an element:
echo '<p id="style">'.$ip['countryName'].'</p>';
echo '<span id="style">'.$ip['countryName'].'</span>';
echo '<div id="style">'.$ip['countryName'].'</div>';
If you want to style both the variables the same style, then set a class like:
echo '<p class="style">'.$ip['cityName'].'</p>';
echo '<p class="style">'.$ip['countryName'].'</p>';
You could also embed the variables within your actual html rather than echoing them out within the code.
$city = $ip['cityName'];
$country = $ip['countryName'];
?>
<div class="style"><?php echo $city ?></div>
<div class="style"><?php echo $country?></div>

Assume you stored that dictionary in a variable called values. To get id
in to a variable, do:
idValue = values['criteria'][0]['id']
If that json is in a file, do the following to load it:
import json
jsonFile = open('your_filename.json', 'r')
values = json.load(jsonFile)
jsonFile.close()
If that json is from a URL, do the following to load it:
import urllib, json
f = urllib.urlopen("http://domain/path/jsonPage")
values = json.load(f)
f.close()
To print ALL of the criteria, you could:
for criteria in values['criteria']:
for key, value in criteria.iteritems():
print key, 'is:', value
print ''

There are two scenarios to compare files:
Scenario 1: Compare files at remote branches (both branches should exists on remote repository)
Scenario 2: Compare local files (at local working area copy) to the files at remote repository.
The logic is simple. If you provide two branch names to diff, it will always compare the remote branches, and if you provide only one branch name, it will always compare your local working copy with the remote repo (the one you provided). You can use range to provide remote repositories.
e.g. Checkout a branch
git checkout branch1
git diff branch2 [filename]
in this case, if you provide filename, it will compare your local copy of filename with remote branch named "branch2".
git diff branch1 branch2 [filename]
in this case, it will compare filename from remote branches named "branch1" vs "branch2"
git diff ..branch2 [filename]
in this case also, it will compare filename from remote branches named "branch1" vs "branch2". So, its same as above. However, if you have just created a branch from another branch, say "master" and your current branch doesn't exists on remote repository, it will compare remote "master" vs remote "branch2".
Hope its useful.

I also read that this is slow, if you want to use it often you should probably use something else.
I don't know why yours is not working, this one is for me, maybe someone else can help...
In the distribution I use, the tasks are listed in the task list by default (at least for Java). For other content types, you may check the following settings.
Display the Tasks View: Window > Show View > Other > General > Tasks
For non-Java Task Tags: check the following settings: Window > Preferences > General > Editors > Structured Text Editors > Task Tags You can enable searching for task tags in the [Task Tags] tab and select the content types in the [Filters] tab.
For Java task tags, you should look in: Window > Preferences > Java > Compiler > Task Tags

As of September 2019 pywin32
is now available from PyPI and installs the latest version (currently version 224). This is done via the pip
command
pip install pywin32
If you wish to get an older version the sourceforge link below would probably have the desired version, if not you can use the command, where xxx
is the version you require, e.g. 224
pip install pywin32==xxx
This differs to the pip
command below as that one uses pypiwin32
which currently installs an older (namely 223)
Browsing the docs I see no reason for these commands to work for all python3.x
versions, I am unsure on python2.7
and below so you would have to try them and if they do not work then the solutions below will work.
Probably now undesirable solutions but certainly still valid as of September 2019
There is no version of specific version ofwin32api
. You have to get the pywin32
module which currently cannot be installed via pip
. It is only available from this link at the moment.
https://sourceforge.net/projects/pywin32/files/pywin32/Build%20220/
The install does not take long and it pretty much all done for you. Just make sure to get the right version of it depending on your python
version :)
EDIT
Since I posted my answer there are other alternatives to downloading the win32api
module.
It is now available to download through pip
using this command;
pip install pypiwin32
Also it can be installed from this GitHub repository as provided in comments by @Heath
You should be using IHtmlString
instead:
IHtmlString str = new HtmlString("<a href="/Home/Profile/seeker">seeker</a> has applied to <a href="/Jobs/Details/9">Job</a> floated by you.</br>");
Whenever you have model properties or variables that need to hold HTML, I feel this is generally a better practice. First of all, it is a bit cleaner. For example:
@Html.Raw(str)
Compared to:
@str
Also, I also think it's a bit safer vs. using @Html.Raw()
, as the concern of whether your data is HTML is kept in your controller. In an environment where you have front-end vs. back-end developers, your back-end developers may be more in tune with what data can hold HTML values, thus keeping this concern in the back-end (controller).
I generally try to avoid using Html.Raw()
whenever possible.
One other thing worth noting, is I'm not sure where you're assigning str
, but a few things that concern me with how you may be implementing this.
First, this should be done in a controller, regardless of your solution (IHtmlString
or Html.Raw
). You should avoid any logic like this in your view, as it doesn't really belong there.
Additionally, you should be using your ViewModel
for getting values to your view (and again, ideally using IHtmlString
as the property type). Seeing something like @Html.Encode(str)
is a little concerning, unless you were doing this just to simplify your example.
Template parameters can be either parameterized by type (typename T) or by value (int X).
The "traditional" C++ way of templating a piece of code is to use a functor - that is, the code is in an object, and the object thus gives the code unique type.
When working with traditional functions, this technique doesn't work well, because a change in type doesn't indicate a specific function - rather it specifies only the signature of many possible functions. So:
template<typename OP>
int do_op(int a, int b, OP op)
{
return op(a,b);
}
int add(int a, int b) { return a + b; }
...
int c = do_op(4,5,add);
Isn't equivalent to the functor case. In this example, do_op is instantiated for all function pointers whose signature is int X (int, int). The compiler would have to be pretty aggressive to fully inline this case. (I wouldn't rule it out though, as compiler optimization has gotten pretty advanced.)
One way to tell that this code doesn't quite do what we want is:
int (* func_ptr)(int, int) = add;
int c = do_op(4,5,func_ptr);
is still legal, and clearly this is not getting inlined. To get full inlining, we need to template by value, so the function is fully available in the template.
typedef int(*binary_int_op)(int, int); // signature for all valid template params
template<binary_int_op op>
int do_op(int a, int b)
{
return op(a,b);
}
int add(int a, int b) { return a + b; }
...
int c = do_op<add>(4,5);
In this case, each instantiated version of do_op is instantiated with a specific function already available. Thus we expect the code for do_op to look a lot like "return a + b". (Lisp programmers, stop your smirking!)
We can also confirm that this is closer to what we want because this:
int (* func_ptr)(int,int) = add;
int c = do_op<func_ptr>(4,5);
will fail to compile. GCC says: "error: 'func_ptr' cannot appear in a constant-expression. In other words, I can't fully expand do_op because you haven't given me enough info at compiler time to know what our op is.
So if the second example is really fully inlining our op, and the first is not, what good is the template? What is it doing? The answer is: type coercion. This riff on the first example will work:
template<typename OP>
int do_op(int a, int b, OP op) { return op(a,b); }
float fadd(float a, float b) { return a+b; }
...
int c = do_op(4,5,fadd);
That example will work! (I am not suggesting it is good C++ but...) What has happened is do_op has been templated around the signatures of the various functions, and each separate instantiation will write different type coercion code. So the instantiated code for do_op with fadd looks something like:
convert a and b from int to float.
call the function ptr op with float a and float b.
convert the result back to int and return it.
By comparison, our by-value case requires an exact match on the function arguments.
Assuming TableA
as an entity of table TableA
, and TableADBEntities
as DB Entity class,
IQueryable<TableA> result;
using (var context = new TableADBEntities())
{
result = context.TableA.Select(s => s);
}
IQueryable<TableA> result;
using (var context = new TableADBEntities())
{
var qry = from s in context.TableA
select s;
result = qry.Select(s => s);
}
Native SQL can also be used as:
IList<TableA> resultList;
using (var context = new TableADBEntities())
{
resultList = context.TableA.SqlQuery("Select * from dbo.TableA").ToList();
}
Note: dbo
is a default schema owner in SQL Server. One can construct a SQL SELECT
query as per the database in the context.
Another way to go
const data: {[key: string]: any} = require('./data.json');
This was you still can define json type is you want and don't have to use wildcard.
For example, custom type json.
interface User {
firstName: string;
lastName: string;
birthday: Date;
}
const user: User = require('./user.json');
I think this would be best explained by the following picture:
To initialize the above, one would type:
import matplotlib.pyplot as plt
fig = plt.figure()
fig.add_subplot(221) #top left
fig.add_subplot(222) #top right
fig.add_subplot(223) #bottom left
fig.add_subplot(224) #bottom right
plt.show()

in Rails 4.2+In Rails 4.2 I had to remove the locals
part and just use size: 30
instead. Otherwise, it wouldn't pass the local variable correctly.
For example, use this:
<%= render @users, size: 30 %>
If you need to find the max/min of a hash, you can use #max_by
or #min_by
people = {'joe' => 21, 'bill' => 35, 'sally' => 24}
people.min_by { |name, age| age } #=> ["joe", 21]
people.max_by { |name, age| age } #=> ["bill", 35]

sound.currentTime = 0;
}
sound.play();
In your PRIMARY KEY definition you've used (id(11))
, which defines a prefix key - i.e. the first 11 characters only should be used to create an index. Prefix keys are only valid for CHAR
, VARCHAR
, BINARY
and VARBINARY
types and your id
field is an int
, hence the error.
Use PRIMARY KEY (id)
instead and you should be fine.

adding this line to the beginning of the file s worked for me:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
modifying the css to set the proper border properties did not work until i added the above line
I'm surprised anyone hasn't said this yet.
Since the asker came from a Java background (and so did I), here's an analogy that helps.
Classes are simply like Java classes.
Modules are like Java static classes. Think about Math
class in Java. You don't instantiate it, and you reuse the methods in the static class (eg. Math.random()
).
I find it odd that (Apache) StringUtils wasn't covered here yet.
you can remove all newlines (or any other occurences of a substring for that matter) from a string using the .replace
method
StringUtils.replace(myString, "\n", "");
This line will replace all newlines with the empty string.
because newline is technically a character you can optionally use the .replaceChars
method that will replace characters
StringUtils.replaceChars(myString, '\n', '');
So interestingly enough this error "Transport endpoint is not connected" was caused by my having more than one Veracrypt device mounted. I closed the extra device and suddenly I had access to the drive. Hmm..
Though this question has an answer, I resolved it differently when I had the same issue. I had this issue when I copied folders with the option Create Folder references
; then the above solution of adding the folder to the build_path worked.
But when the folder was added using the Create groups for any added folder
option, the headers were picked up automatically.
If you happen to be an iOS developer
:
Check how many simulators that you have downloaded as they take up a lot of space:
Go to: ~/Library/Developer/Xcode/iOS DeviceSupport
Also delete old archived apps:
Go to: ~/Library/Developer/Xcode/Archives
I cleared 100GB doing this.
Beware of recipes like this
target:
MY_ID=$(GENERATE_ID);
echo $MY_ID;
It does two things wrong. The first line in the recipe is executed in a separate shell instance from the second line. The variable is lost in the meantime. Second thing wrong is that the $
is not escaped.
target:
MY_ID=$(GENERATE_ID); \
echo $$MY_ID;
Both problems have been fixed and the variable is useable. The backslash combines both lines to run in one single shell, hence the setting of the variable and the reading of the variable afterwords, works.
I realize the original post said how to get the results of a shell command into a MAKE variable, and this answer shows how to get it into a shell variable. But other readers may benefit.
One final improvement, if the consumer expects an "environment variable" to be set, then you have to export it.
my_shell_script
echo $MY_ID
would need this in the makefile
target:
export MY_ID=$(GENERATE_ID); \
./my_shell_script;
Hope that helps someone. In general, one should avoid doing any real work outside of recipes, because if someone use the makefile with '--dry-run' option, to only SEE what it will do, it won't have any undesirable side effects. Every $(shell)
call is evaluated at compile time and some real work could accidentally be done. Better to leave the real work, like generating ids, to the inside of the recipes when possible.
JavaScript is a dynamically typed language. This means that you never need to declare the type of a function argument (or any other variable). So, your code will work as long as arrayP
is an array and contains elements with a value
property.
An other way which makes then your jsfiddle less buggy (needed double click on open).
This doesn't use any delegated event to body level
Set tabindex="-1"
to DIV .popup ( and for style CSS outline:0
)
$(".link").click(function(e){
e.preventDefault();
$(".popup").fadeIn(300,function(){$(this).focus();});
});
$('.close').click(function() {
$(".popup").fadeOut(300);
});
$(".popup").on('blur',function(){
$(this).fadeOut(300);
});
To open hyperlink in the same tab, use:
$(document).on('click', "a.classname", function() {
var form = $("<form></form>");
form.attr(
{
id : "formid",
action : $(this).attr("href"),
method : "GET",
});
$("body").append(form);
$("#formid").submit();
$("#formid").remove();
return false;
});
var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'
If I understand what you're asking, this should do the trick:
// the more standards compliant browsers (mozilla/netscape/opera/IE7) use
// window.innerWidth and window.innerHeight
var windowHeight;
if (typeof window.innerWidth != 'undefined')
{
windowHeight = window.innerHeight;
}
// IE6 in standards compliant mode (i.e. with a valid doctype as the first
// line in the document)
else if (typeof document.documentElement != 'undefined'
&& typeof document.documentElement.clientWidth != 'undefined'
&& document.documentElement.clientWidth != 0)
{
windowHeight = document.documentElement.clientHeight;
}
// older versions of IE
else
{
windowHeight = document.getElementsByTagName('body')[0].clientHeight;
}
document.getElementById("yourDiv").height = windowHeight - 300 + "px";
If your run button is gray. This is how i fixed it.
Go to Run in menu, and then press this:
Then it will run your Emulator, and your run button will become green again and you can use it. That is how i fixed it.

This is a very basic PHP Form validation. This could be put in a try
block, but for basic reference, I see this fit following our conversation in the comment box.
What this script will do, is process each of the post elements, and act accordingly, for example:
if (!filter_var($Input_Email, FILTER_VALIDATE_EMAIL))
{
$ErrorArrays[] = "Incorrect Email Formatting";
}
This will check:
if $Input_Email is not a valid email. If this is not a valid E-mail, then a message will get added to a empty array.
Further down the script, you will see:
if (count($ErrorArrays) == 0)
{
// No Errors
}
else
{
foreach ($ErrorArrays AS $Errors)
{
echo "<font color='red'><b>".$Errors."</font></b><br>";
}
}
Basically. if the array count is not 0, errors have been found. Then the script will print out the errors.
Remember, this is a reference based on our conversation in the comment box, and should be used as such.
First of all: officially, the correct question would be
web services + WSDL + SOAP
vsREST
.Because, although the web service, is used in the loose sense, when using the HTTP protocol to transfer data instead of web pages, officially it is a very specific form of that idea. According to the definition, REST is not "web service".
In practice however, everyone ignores that, so let's ignore it too
There are already technical answers, so I'll try to provide some intuition.
Let's say you want to call a function in a remote computer, implemented in some other programming language (this is often called remote procedure call/RPC). Assume that function can be found at a specific URL, provided by the person who wrote it. You have to (somehow) send it a message, and get some response. So, there are two main questions to consider.
For the first question, the official definition is WSDL. This is an XML file which describes, in detailed and strict format, what are the parameters, what are their types, names, default values, the name of the function to be called, etc. An example WSDL here shows that the file is human-readable (but not easily).
For the second question, there are various answers. However, the only one used in practice is SOAP. Its main idea is: wrap the previous XML (the actual message) into yet another XML (containing encoding info and other helpful stuff), and send it over HTTP. The POST method of the HTTP is used to send the message, since there is always a body.
The main idea of this whole approach is that you map a URL to a function, that is, to an action. So, if you have a list of customers in some server, and you want to view/update/delete one, you must have 3 URLS:
myapp/read-customer
and in the body of the message, pass the id of the customer to be read.myapp/update-customer
and in the body, pass the id of the customer, as well as the new datamyapp/delete-customer
and the id in the bodyThe REST approach sees things differently. A URL should not represent an action, but a thing (called resource in the REST lingo). Since the HTTP protocol (which we are already using) supports verbs, use those verbs to specify what actions to perform on the thing.
So, with the REST approach, customer number 12 would be found on URL myapp/customers/12
. To view the customer data, you hit the URL with a GET request. To delete it, the same URL, with a DELETE verb. To update it, again, the same URL with a POST verb, and the new content in the request body.
For more details about the requirements that a service has to fulfil to be considered truly RESTful, see the Richardson maturity model. The article gives examples, and, more importantly, explains why a (so-called) SOAP service, is a level-0 REST service (although, level-0 means low compliance to this model, it's not offensive, and it is still useful in many cases).
Explanation from the Preshing on Programming blog:
It’s handy when you have two related operations which you’d like to execute as a pair, with a block of code in between. The classic example is opening a file, manipulating the file, then closing it:
with open('output.txt', 'w') as f: f.write('Hi there!')
The above with statement will automatically close the file after the nested block of code. (Continue reading to see exactly how the close occurs.) The advantage of using a with statement is that it is guaranteed to close the file no matter how the nested block exits. If an exception occurs before the end of the block, it will close the file before the exception is caught by an outer exception handler. If the nested block were to contain a return statement, or a continue or break statement, the with statement would automatically close the file in those cases, too.
For those who still have problems after attempting the suggestions above: I solved the issue by updating the maven project.
Assuming the connection is established and is available in global scope;
//Check if a value exists in a table
function record_exists ($table, $column, $value) {
global $connection;
$query = "SELECT * FROM {$table} WHERE {$column} = {$value}";
$result = mysql_query ( $query, $connection );
if ( mysql_num_rows ( $result ) ) {
return TRUE;
} else {
return FALSE;
}
}
Usage: Assuming that the value to be checked is stored in the variable $username;
if (record_exists ( 'employee', 'username', $username )){
echo "Username is not available. Try something else.";
} else {
echo "Username is available";
}
You can use:
SELECT CONVERT(datetime, '24.04.2012', 103) AS Date
Reference: CAST and CONVERT (Transact-SQL)
You can do this in jEdit, by using the "Return value of a BeanShell snippet" option in jEdit's find and replace dialog. Just search for " [a-z]"
and replace it by " _0.toUpperCase()"
(without quotes)
Use static_cast<int>
:
int num = static_cast<int>(letter); // if letter='a', num=97
Edit: You probably should try to avoid to use (int)
int num = (int) letter;
check out Why use static_cast<int>(x) instead of (int)x? for more info.
First make sure that you've installed the plugin, but it's likely that the workspace directory isn't properly set. Just check Pylint and edit the underlying settings.json file.
{
"python.pythonPath": "/usr/local/bin/python3",
"git.ignoreLimitWarning": true
}
After reading all of the answers I ended up with this version with + a second function to use parameters as flags
function getURLParameter(name) {
return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)','i').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null;
}
function isSetURLParameter(name) {
return (new RegExp('[?|&]' + name + '(?:[=|&|#|;|]|$)','i').exec(location.search) !== null)
}
If anyone came to this question looking for ways to add multiple parameters at the same time (my case), you can use .params
with a MultivalueMap instead of adding each .param
:
LinkedMultiValueMap<String, String> requestParams = new LinkedMultiValueMap<>()
requestParams.add("id", "1");
requestParams.add("name", "john");
requestParams.add("age", "30");
mockMvc.perform(get("my/endpoint").params(requestParams)).andExpect(status().isOk())
Assuming the question is about cleaning the workspace of the current job, you can run:
test -n "$WORKSPACE" && rm -rf "$WORKSPACE"/*
In my case, the request was getting timed out. So all you need to do is to increase the time out while creating the HttpClient.
HttpClient client = new HttpClient();
client.Timeout = TimeSpan.FromMinutes(5);
Since column-ordering doesn't work in Bootstrap 4 beta as described in the code provided in the revisited answer above, you would need to use the following (as indicated in the codeply 4 Flexbox order demo - alpha/beta links that were provided in the answer).
<div class="container">
<div class="row">
<div class="col-3 col-md-6">
<div class="card card-block">1</div>
</div>
<div class="col-6 col-md-12 flex-md-last">
<div class="card card-block">3</div>
</div>
<div class="col-3 col-md-6 ">
<div class="card card-block">2</div>
</div>
</div>
Note however that the "Flexbox order demo - beta" goes to an alpha codebase, and changing the codebase to Beta (and running it) results in the divs incorrectly displaying in a single column -- but that looks like a codeply issue since cutting and pasting the code out of codeply works as described.
cout.fill( '0' );
cout.width( 3 );
cout << value;
Just set this extra line in catalina.bat

Be careful with the "Range(...)" without first qualifying a Worksheet because it will use the currently Active worksheet to make the copy from. It's best to fully qualify both sheets. Please give this a shot (please change "Sheet1" with the copy worksheet):
EDIT: edited for pasting values only based on comments below.

Application.ScreenUpdating = False
Dim copySheet As Worksheet
Dim pasteSheet As Worksheet
Set copySheet = Worksheets("Sheet1")
Set pasteSheet = Worksheets("Sheet2")

pasteSheet.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).PasteSpecial xlPasteValues

With ES6, you can now use the spread operator to create a new array with your new elements inserted before the original elements.
// Prepend a single item._x000D_
const a = [1, 2, 3];_x000D_
console.log([0, ...a]);
_x000D_
// Prepend an array._x000D_
const a = [2, 3];_x000D_
const b = [0, 1];_x000D_
console.log([...b, ...a]);
_x000D_
I intended this answer to present an alternative syntax that I think is more memorable and concise. It should be noted that according to some benchmarks (see this other answer), this syntax is significantly slower. This is probably not going to matter unless you are doing many of these operations in a loop.
jsonify
serializes the data you pass it to JSON. If you want to serialize the data yourself, do what jsonify
does by building a response with status=200
and mimetype='application/json'
.
from flask import json
@app.route('/summary')
def summary():
data = make_summary()
response = app.response_class(
response=json.dumps(data),
status=200,
mimetype='application/json'
)
return response
After an update the Android Studio does not show the layout's design for some reason. I tried newer versions as well, but it did not work. So I decided to downgrade my IDE.
When I opened my project, I got the same error. The solution was the following:
Or if you don't mind, then you can update your AS.
enumerate
is what you want:
for i, s in enumerate(S):
print s, i
I couldn't find an off-the-shelf module that added this function, so I wrote one:
In Access, go to the Database Tools ribbon, in the Macro area click into Visual Basic. In the top left Project area, right click the name of your file and select Insert -> Module. In the module paste this:
Public Function Substring_Index(strWord As String, strDelim As String, intCount As Integer) As String
Substring_Index = delims
start = 0
test = ""
For i = 1 To intCount
oldstart = start + 1
start = InStr(oldstart, strWord, strDelim)
Substring_Index = Mid(strWord, oldstart, start - oldstart)
Next i
End Function
Save the module as module1 (the default). You can now use statements like:
SELECT Substring_Index([fieldname],",",2) FROM table

I had the same issue. However making the view 1px didn't seem to work on my original Nexus 7. I noticed that the screen density was 213 which is less than the 240 used in xhdpi. So it was thinking the device was an mdpi density.
My solution was to make it so the dimens
folder had a dividerHeight
parameter. I set it to 2dp
in the values-mdpi
folder but 1dp
in the values-hdpi
etc folders.
If an object's property may refer to some other object then you can test that for undefined before trying to use its properties:
if (thing && thing.foo)
alert(thing.foo.bar);
I could update my answer to better reflect your situation if you show some actual code, but possibly something like this:
function someFunc(parameterName) {
if (parameterName && parameterName.foo)
alert(parameterName.foo.bar);
}
We can add scroll bar even without using Canvas. I have read it in many other post we can't add vertical scroll bar in frame directly etc etc. But after doing many experiment found out way to add vertical as well as horizontal scroll bar :). Please find below code which is used to create scroll bar in treeView and frame.

Cors issue has been faced in my application. refer above screenshot. After adding proxy config issue has been resolved. my application url: localhost:4200 and requesting api url:"http://www.datasciencetoolkit.org/maps/api/geocode/json?sensor=false&address="
Api side no-cors permission allowed. And also I'm not able to change cors-issue in server side and I had to change only in angular(client side).
Steps to resolve:
{ "/maps/*": { "target": "http://www.datasciencetoolkit.org", "secure": false, "logLevel": "debug", "changeOrigin": true } }
this.http .get<GeoCode>('maps/api/geocode/json?sensor=false&address=' + cityName) .pipe( tap(cityResponse => this.responseCache.set(cityName, cityResponse)) );
Note: We have skip hostname name url in Api request, it will auto add while giving request. whenever changing proxy.conf.js we have to restart ng-serve, then only changes will update.
"serve": { "builder": "@angular-devkit/build-angular:dev-server", "options": { "browserTarget": "TestProject:build", "proxyConfig": "src/proxy.conf.json" }, "configurations": { "production": { "browserTarget": "TestProject:build:production" } } },
After finishing these step restart ng-serve Proxy working correctly as expect refer here

If you use random
instead of * random
your code not give any error

Try this instead:
var responseObject = proxy.CallService(new RequestObject
{
Data = "misc. data",
Guid = new Guid.NewGuid()
});
This will generate a 'real' Guid value. When you new a reference type, it will give you the default value (which in this case, is all zeroes for a Guid).
When you create a new Guid, it will initialize it to all zeroes, which is the default value for Guid. It's basically the same as creating a "new" int (which is a value type but you can do this anyways):
Guid g1; // g1 is 00000000-0000-0000-0000-000000000000
Guid g2 = new Guid(); // g2 is 00000000-0000-0000-0000-000000000000
Guid g3 = default(Guid); // g3 is 00000000-0000-0000-0000-000000000000
Guid g4 = Guid.NewGuid(); // g4 is not all zeroes
Compare this to doing the same thing with an int:
int i1; // i1 is 0
int i2 = new int(); // i2 is 0
int i3 = default(int); // i3 is 0
Apply this class to it

With Pandas version =1.0.0, I would use DataFrame.replace
or Series.replace
:
df.replace(old_val, pd.NA, inplace=True)
This is better for two reasons:
pd.NA
instead of None
or np.nan

Operating System : Windows 10 Version 1703 (x64)
I faced this error while debugging my C# .Net project in Visual Studio 2017 Community edition. I was calling a native method by performing p/invoke on a C++ assembly loaded at run-time. I encountered the very same error reported by OP.
I realized that Visual Studio was launched with a user account which was not an administrator on the machine. Then I relaunched Visual Studio under a different user account which was an administrator on the machine. That's all. My problem got resolved and I didn't face the issue again.
One thing to note is that the method which was being invoked on C++ assembly was supposed to write few things in registry. I didn't go debugging the C++ code to do some RCA but I see a possibility that the whole thing was failing as administrative privileges are required to write registry in Windows 10 operating system. So earlier when Visual Studio was running under a user account which didn't have administrative privileges on the machine, then the native calls were failing.
I had the same exact issue. As @weiweia suggested, move the code from the java directory to src worked for me. I also removed the Android Dependencies from Project --> Properties --> Java Build Path --> Order and Export, and made sure only to include Library Projects in the Android screen.
React Native hasn't provided the gradient color yet. But still, you can do it with a nmp package called react-native-linear-gradient
or you can click here for more info
npm install react-native-linear-gradient --save

Before installing libgtk2.0-dev and pkg-config or libqt4-dev. Make sure that you have uninstalled opencv. You can confirm this by running import cv2 on your python shell. If it fails, then install the needed packages and re-run cmake .
Pass the decode pattern to ParseExact
Dim d as string = "201210120956"
Dim dt = DateTime.ParseExact(d, "yyyyMMddhhmm", Nothing)
ParseExact is available only from Net FrameWork 2.0.
If you are still on 1.1 you could use Parse, but you need to provide the IFormatProvider adequate to your string
Run the following query from Management Studio on a running process:
DBCC inputbuffer( spid# )
This will return the SQL currently being run against the database for the SPID provided. Note that you need appropriate permissions to run this command.
This is better than running a trace since it targets a specific SPID. You can see if it's long running based on its CPUTime and DiskIO.
Example to get details of SPID 64:
DBCC inputbuffer(64)
Objective C Solution
NSArray * array = @[@"1", @"2", @"3"];
NSString * stringFromArray = [[array valueForKey:@"description"] componentsJoinedByString:@"-"]; // "1-2-3"
Those who are looking for a solution in Swift
If the array contains strings, you can use the String's join method:
var array = ["1", "2", "3"]
let stringFromArray = "-".join(array) // "1-2-3"
In Swift 2:
var array = ["1", "2", "3"]
let stringFromArray = array.joinWithSeparator("-") // "1-2-3"
In Swift 3 & 4
var array = ["1", "2", "3"]
let stringFromArray = array.joined(separator: "-") // "1-2-3"

Different approach for creating columns string
create table #temp
(
date datetime,
category varchar(3),
amount money
)
insert into #temp values ('1/1/2012', 'ABC', 1000.00)
insert into #temp values ('2/1/2012', 'DEF', 500.00)
insert into #temp values ('2/1/2012', 'GHI', 800.00)
insert into #temp values ('2/10/2012', 'DEF', 700.00)
insert into #temp values ('3/1/2012', 'ABC', 1100.00)
DECLARE @cols AS NVARCHAR(MAX)='';
DECLARE @query AS NVARCHAR(MAX)='';
SELECT @cols = @cols + QUOTENAME(category) + ',' FROM (select distinct category from #temp ) as tmp
select @cols = substring(@cols, 0, len(@cols)) --trim "," at end
set @query =
'SELECT * from
(
select date, amount, category from #temp
) src
pivot
(
max(amount) for category in (' + @cols + ')
) piv'
execute(@query)
drop table #temp

A delegate is a class that wraps a pointer or reference to an object instance, a member method of that object's class to be called on that object instance, and provides a method to trigger that call.
Here's an example:
template <class T>
class CCallback
{
public:
typedef void (T::*fn)( int anArg );
CCallback(T& trg, fn op)
: m_rTarget(trg)
, m_Operation(op)
{
}
void Execute( int in )
{
(m_rTarget.*m_Operation)( in );
}
private:
CCallback();
CCallback( const CCallback& );
T& m_rTarget;
fn m_Operation;
};
class A
{
public:
virtual void Fn( int i )
{
}
};
int main( int /*argc*/, char * /*argv*/ )
{
A a;
CCallback<A> cbk( a, &A::Fn );
cbk.Execute( 3 );
}
I was over-complicating myself. After taking a long break and coming back, the desired output could be accomplished by this simple query:
SELECT Sandwiches.[Sandwich Type], Sandwich.Bread, Count(Sandwiches.[SandwichID]) AS [Total Sandwiches]
FROM Sandwiches
GROUP BY Sandwiches.[Sandwiches Type], Sandwiches.Bread;
Thanks for answering, it helped my train of thought.
Yes, there is - python may not be in /usr/bin

This error is pretty self-explanatory. There seem to be data missing in the first line of your data file (or second line, as the case may be since you're using header = TRUE
).
Here's a mini example:
## Create a small dataset to play with
cat("V1 V2\nFirst 1 2\nSecond 2\nThird 3 8\n", file="test.txt")
R automatically detects that it should expect rownames plus two columns (3 elements), but it doesn't find 3 elements on line 2, so you get an error:
read.table("test.txt", header = TRUE)
# Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
# line 2 did not have 3 elements
Look at the data file and see if there is indeed a problem:
cat(readLines("test.txt"), sep = "\n")
# V1 V2
# First 1 2
# Second 2
# Third 3 8
Manual correction might be needed, or we can assume that the value first value in the "Second" row line should be in the first column, and other values should be NA
. If this is the case, fill = TRUE
is enough to solve your problem.
read.table("test.txt", header = TRUE, fill = TRUE)
# V1 V2
# First 1 2
# Second 2 NA
# Third 3 8
R is also smart enough to figure it out how many elements it needs even if rownames are missing:
cat("V1 V2\n1\n2 5\n3 8\n", file="test2.txt")
cat(readLines("test2.txt"), sep = "\n")
# V1 V2
# 1
# 2 5
# 3 8
read.table("test2.txt", header = TRUE)
# Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
# line 1 did not have 2 elements
read.table("test2.txt", header = TRUE, fill = TRUE)
# V1 V2
# 1 1 NA
# 2 2 5
# 3 3 8

You can do it programatically:
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
public class ActivityName extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
Or you can do it via your AndroidManifest.xml
file:
<activity android:name=".ActivityName"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">

The question is kind of old, but I get a good result creating a function to convert an object in a Json string from a string variable to an integer
function getInt(arr, prop) {
var int;
for (var i=0 ; i<arr.length ; i++) {
int = parseInt(arr[i][prop])
arr[i][prop] = int;
}
return arr;
}
the function just go thru the array and return all elements of the object of your selection as an integer

You can use Forever, A simple CLI tool for ensuring that a given node script runs continuously (i.e. forever): https://www.npmjs.org/package/forever
If you're interested in a data.table
solution, here's one. It's a bit tricky since you prefer to get the id for the first maximum. It's much easier if you'd rather want the last maximum. Nevertheless, it's not that complicated and it's fast!
Here I've generated data of your dimensions (26746 * 18).
set.seed(45)
DF <- data.frame(matrix(sample(10, 26746*18, TRUE), ncol=18))
data.table
answer:require(data.table)
DT <- data.table(value=unlist(DF, use.names=FALSE),
colid = 1:nrow(DF), rowid = rep(names(DF), each=nrow(DF)))
setkey(DT, colid, value)
t1 <- DT[J(unique(colid), DT[J(unique(colid)), value, mult="last"]), rowid, mult="first"]
# data.table solution
system.time({
DT <- data.table(value=unlist(DF, use.names=FALSE),
colid = 1:nrow(DF), rowid = rep(names(DF), each=nrow(DF)))
setkey(DT, colid, value)
t1 <- DT[J(unique(colid), DT[J(unique(colid)), value, mult="last"]), rowid, mult="first"]
})
# user system elapsed
# 0.174 0.029 0.227
# apply solution from @thelatemail
system.time(t2 <- colnames(DF)[apply(DF,1,which.max)])
# user system elapsed
# 2.322 0.036 2.602
identical(t1, t2)
# [1] TRUE
It's about 11 times faster on data of these dimensions, and data.table
scales pretty well too.
DT <- data.table(value=unlist(DF, use.names=FALSE),
colid = 1:nrow(DF), rowid = rep(names(DF), each=nrow(DF)))
setkey(DT, colid, value)
t1 <- DT[J(unique(colid)), rowid, mult="last"]

I feel sum(d.values())
is the most efficient way to get the sum.
You can also try the reduce function to calculate the sum along with a lambda expression:
reduce(lambda x,y:x+y,d.values())
I was struggling with the same problem and found one solution. I guess it can help you. when you run python manage.py runserver, it will take 127.0.0.1 as default ip address and 8000. 127.0.0.0 is the same as localhost which can be accessed locally. to access it from cross origin you need to run it on your system ip or 0.0.0.0. 0.0.0.0 can be accessed from any origin in the network. for port number, you need to set inbound and outbound policy of your system if you want to use your own port number not the default one.
To do this you need to run server with command python manage.py runserver 0.0.0.0:<your port>
as mentioned above
or, set a default ip and port in your python environment. For this see my answer on django change default runserver port

If we have a dynamic value that needs to go in a css background or background-image attribute, it can be just a bit more tricky to specify.
Let’s say we have a getImage() function in our controller. This function returns a string formatted similar to this: url(icons/pen.png). If we do, the ngStyle declaration is specified the exact same way as before:
ng-style="{ 'background-image': getImage() }"
Make sure to put quotes around the background-image key name. Remember, this must be formatted as a valid Javascript object key.

Netbeans is just like any other java application which requires tuning for its JVM.
Please read the following link to have some benchmark results for netbeans
https://performance.netbeans.org/reports/gc/
The following settings works fine in my Windows 7 PC with 4GB RAM and I5 Quad core processor.
(Check for the line netbeans_default_options in the netbeans config file inside bin folder and replace the config line as follows)
netbeans_default_options="-XX:TargetSurvivorRatio=1 -Xverify:none -XX:PermSize=100M -Xmx500m -Xms500m -XX+UseParallelGC ${netbeans_default_options}"
Small Suggestion: Garbage collection plays a vital part in JVM heap size and since I had a quad core processor, I used Parallel GC. If you have single thread processor, please use UseSerialGC. From my experience, if Xmx Xms values are same, there is no performance overhead for JVM to switch between min and max values. In my case, whenever my app size tries to exceed 500MB, the parallel GC comes in handy to cleanup unwanted garbage so my app never exceed 500MB in my PC.
You said you choose to store your numbers with the double type. I think this could be the root of the problem, because it forces you to store integers into doubles (and therefore losing the initial information about the value's nature). What about storing your numbers in instances of the Number class (superclass of both Double and Integer) and rely on polymorphism to determine the correct format of each number?
I know it may not be acceptable to refactor a whole part of your code due to that, but it could produce the desired output without extra code/casting/parsing.
Example:
import java.util.ArrayList;
import java.util.List;
public class UseMixedNumbers {
public static void main(String[] args) {
List<Number> listNumbers = new ArrayList<Number>();
listNumbers.add(232);
listNumbers.add(0.18);
listNumbers.add(1237875192);
listNumbers.add(4.58);
listNumbers.add(0);
listNumbers.add(1.2345);
for (Number number : listNumbers) {
System.out.println(number);
}
}
}
Will produce the following output:
232
0.18
1237875192
4.58
0
1.2345
To add to Pratik's answer, here is a modified version where user can enter min 2 digits also , for example, 15 to 100:
import android.text.InputFilter;
import android.text.Spanned;
public class InputFilterMinMax implements InputFilter {
private int min, max;
public InputFilterMinMax(int min, int max) {
this.min = min;
this.max = max;
}
public InputFilterMinMax(String min, String max) {
this.min = Integer.parseInt(min);
this.max = Integer.parseInt(max);
}
@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
try {
if(end==1)
min=Integer.parseInt(source.toString());
int input = Integer.parseInt(dest.toString() + source.toString());
if (isInRange(min, max, input))
return null;
} catch (NumberFormatException nfe) {
}
return "";
}
private boolean isInRange(int a, int b, int c) {
return b > a ? c >= a && c <= b : c >= b && c <= a;
}}
added: if(end==1) min=Integer.parseInt(source.toString());
Hope this helps. kindly dont downvote without reasons.
Do copy the whole file inside the vim or its tabs
y G
then move to a tab and paste by
p
and to cut the whole file use
d G
Can be done via slicing too
package main
import "fmt"
func main() {
fmt.Print("HELLO"[1:2])
}
NOTE: This solution only works for ASCII characters.
While probably not as clean looking as the IConvertible
approach, you could always use the straightforward checking typeof(T)
to return a T
:
public static T ReturnType<T>(string stringValue)
{
if (typeof(T) == typeof(int))
return (T)(object)1;
else if (typeof(T) == typeof(FooBar))
return (T)(object)new FooBar(stringValue);
else
return default(T);
}
public class FooBar
{
public FooBar(string something)
{}
}
You can hold onto the percentage as decimal (value \ total)
and then when you want to render to a human you can make use of Habeeb's answer or using string interpolation you could have something even cleaner:
var displayPercentage = $"{(decimal)value / total:P}";
or
//Calculate percentage earlier in code
decimal percentage = (decimal)value / total;
...
//Now render percentage
var displayPercentage = $"{percentage:P}";
For bash scripts this would be the easiest way:
# In the form major.minor.micro e.g. '3.6.8'
# The second part excludes the 'Python ' prefix
PYTHON_VERSION=`python3 --version | awk '{print $2}'`
echo "python3 version: ${PYTHON_VERSION}"
python3 version: 3.6.8
And if you just need the major.minor
version (e.g. 3.6
) you can either use the above and then pick the first 3 characters:
PYTHON_VERSION=`python3 --version | awk '{print $2}'`
echo "python3 major.minor: ${PYTHON_VERSION:0:3}"
python3 major.minor: 3.6
or
PYTHON_VERSION=`python3 -c 'import sys; print(str(sys.version_info[0])+"."+str(sys.version_info[1]))'`
echo "python3 major.minor: ${PYTHON_VERSION}"
python3 major.minor: 3.6
Requirements:
moment().fromNow()
functionality."today"
, "yesterday"
, "tomorrow"
, etc.Solution:
// call this function, passing-in your date
function dateToFromNowDaily( myDate ) {
// get from-now for this date
var fromNow = moment( myDate ).fromNow();
// ensure the date is displayed with today and yesterday
return moment( myDate ).calendar( null, {
// when the date is closer, specify custom values
lastWeek: '[Last] dddd',
lastDay: '[Yesterday]',
sameDay: '[Today]',
nextDay: '[Tomorrow]',
nextWeek: 'dddd',
// when the date is further away, use from-now functionality
sameElse: function () {
return "[" + fromNow + "]";
}
});
}
NB: From version 2.14.0, the formats argument to the calendar function can be a callback, see http://momentjs.com/docs/#/displaying/calendar-time/.
I don't want to sound too negative, but there are occasions when what you want is almost impossible without a lot of "artificial" tuning of page breaks.
If the callout falls naturally near the bottom of a page, and the figure falls on the following page, moving the figure back one page will probably displace the callout forward.
I would recommend (as far as possible, and depending on the exact size of the figures):
In my experience, this is a big eater-up of non-available time (:-)

Just FYI, you could use the VB.NET Like-Operator:
string text = "x is not the same as X and yz not the same as YZ";
bool contains = LikeOperator.LikeString(text,"*X*YZ*", Microsoft.VisualBasic.CompareMethod.Binary);
Use CompareMethod.Text
if you want to ignore the case.
You need to add using Microsoft.VisualBasic.CompilerServices;

you can use DateTime.ParseExact
with the format string
DateTime dt = DateTime.ParseExact(inputString, formatString, System.Globalization.CultureInfo.InvariantCulture);
Above will throw an exception if the given string not in given format.
use DateTime.TryParseExact
if you don't need exception in case of format incorrect but you can check the return value of that method to identify whether parsing value success or not.

32-bit Java is limited to approximately 1.4 to 1.6 GB.
Quote
The maximum theoretical heap limit for the 32-bit JVM is 4G. Due to various additional constraints such as available swap, kernel address space usage, memory fragmentation, and VM overhead, in practice the limit can be much lower. On most modern 32-bit Windows systems the maximum heap size will range from 1.4G to 1.6G. On 32-bit Solaris kernels the address space is limited to 2G. On 64-bit operating systems running the 32-bit VM, the max heap size can be higher, approaching 4G on many Solaris systems.
The above answer did not work for me -
The following worked
$('input[type=checkbox]').each(function()
{
this.checked = false;
});
This makes sure all the checkboxes are unchecked.
Joshua P Nixon's answer is correct but I had to set last modified date also. so here is the code.
var file = new File([blob], "file_name", {lastModified: 1534584790000});
1534584790000 is an unix timestamp for "GMT: Saturday, August 18, 2018 9:33:10 AM"
REST means working with the standards of the web, and the standard for "secure" transfer on the web is SSL. Anything else is going to be kind of funky and require extra deployment effort for clients, which will have to have encryption libraries available.
Once you commit to SSL, there's really nothing fancy required for authentication in principle. You can again go with web standards and use HTTP Basic auth (username and secret token sent along with each request) as it's much simpler than an elaborate signing protocol, and still effective in the context of a secure connection. You just need to be sure the password never goes over plain text; so if the password is ever received over a plain text connection, you might even disable the password and mail the developer. You should also ensure the credentials aren't logged anywhere upon receipt, just as you wouldn't log a regular password.
HTTP Digest is a safer approach as it prevents the secret token being passed along; instead, it's a hash the server can verify on the other end. Though it may be overkill for less sensitive applications if you've taken the precautions mentioned above. After all, the user's password is already transmitted in plain-text when they log in (unless you're doing some fancy JavaScript encryption in the browser), and likewise their cookies on each request.
Note that with APIs, it's better for the client to be passing tokens - randomly generated strings - instead of the password the developer logs into the website with. So the developer should be able to log into your site and generate new tokens that can be used for API verification.
The main reason to use a token is that it can be replaced if it's compromised, whereas if the password is compromised, the owner could log into the developer's account and do anything they want with it. A further advantage of tokens is you can issue multiple tokens to the same developers. Perhaps because they have multiple apps or because they want tokens with different access levels.
(Updated to cover implications of making the connection SSL-only.)

You can always append the '%' by itself without any other format specifiers in the string you are appending, like so...
int test = 10;
NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [stringTest stringByAppendingString:@"%"];
NSLog(@"%@", stringTest);
For iOS7.0+
To expand the answer to other characters that might cause you conflict you may choose to use:
- (NSString *)stringByAddingPercentEncodingWithAllowedCharacters:(NSCharacterSet *)allowedCharacters
Written out step by step it looks like this:
int test = 10;
NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [[stringTest stringByAppendingString:@"%"]
stringByAddingPercentEncodingWithAllowedCharacters:
[NSCharacterSet alphanumericCharacterSet]];
stringTest = [stringTest stringByRemovingPercentEncoding];
NSLog(@"percent value of test: %@", stringTest);
Or short hand:
NSLog(@"percent value of test: %@", [[[[NSString stringWithFormat:@"%d", test]
stringByAppendingString:@"%"] stringByAddingPercentEncodingWithAllowedCharacters:
[NSCharacterSet alphanumericCharacterSet]] stringByRemovingPercentEncoding]);
Thanks to all the original contributors. Hope this helps. Cheers!
Very old but I have just struggled with this, this is how I solved it in pure xml. In res/values/colors.xml I added three colours (the colour_...);
<resources>
<color name="black_overlay">#66000000</color>
<color name="colour_highlight_grey">#ff666666</color>
<color name="colour_dark_blue">#ff000066</color>
<color name="colour_dark_green">#ff006600</color>
</resources>
In the res/drawable folder I created listview_colours.xml which contained;
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/colour_highlight_grey" android:state_pressed="true"/>
<item android:drawable="@color/colour_dark_blue" android:state_selected="true"/>
<item android:drawable="@color/colour_dark_green" android:state_activated="true"/>
<item android:drawable="@color/colour_dark_blue" android:state_focused="true"/>
</selector>
In the main_activity.xml find the List View and add the drawable to listSelector;
<ListView
android:id="@+id/menuList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:listSelector="@drawable/listview_colours"
android:background="#ff222222"/>
</LinearLayout>
Play with the state_... items in the listview_colours.xml to get the effect you want.
There is also a method where you can set the style of the List View but I never managed to get it to work
http://localhost:80/phpmyadmin/
or if you changed port from httpd.conf write port number instead of 80.
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
public class MyServlet extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response) throws IOException
{
response.setContentType("text/html");
PrintWriter pw=response.getWriter();
pw.println("<b><centre>Redirecting to Google<br>");
response.setHeader("refresh,"5;https://www.google.com/"); // redirects to url after 5 seconds
pw.close();
}
}
Zambri's answer found here is the best.
File.open("out.txt", '<OPTION>') {|f| f.write("write your stuff here") }
where your options for <OPTION>
are:
r
- Read only. The file must exist.
w
- Create an empty file for writing.
a
- Append to a file.The file is created if it does not exist.
r+
- Open a file for update both reading and writing. The file must exist.
w+
- Create an empty file for both reading and writing.
a+
- Open a file for reading and appending. The file is created if it does not exist.
In your case, w
is preferable.
You can make a CustomScrollView, for which you can disable its interference with other views. Though this can be sometimes irritating for the end user. Use it with caution.
This is the code:
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.ViewParent;
public class CustomScrollView extends android.widget.ScrollView {
public CustomScrollView(Context context) {
super(context);
}
public CustomScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomScrollView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev)
{
/* Prevent parent controls from stealing our events once we've gotten a touch down */
if (ev.getActionMasked() == MotionEvent.ACTION_DOWN)
{
ViewParent p = getParent();
if (p != null)
p.requestDisallowInterceptTouchEvent(true);
}
return false;
}
}
How to use the CustomScrollView?
You can add CustomScrollView as a parent to the screen in which you want to add another Scrollview as a child view, and the whole screen is scrollable. I used this for a RelativeLayout.
<?xml version="1.0" encoding="utf-8"?>
<**package.**CustomScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/some_id"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:tools="http://schemas.android.com/tools">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
#**Inside this I had a TableLayout and TableRow. Inside the TableRow,**
#**I had a TextView which I made scrollable from Java Code.**
#**textView.setMovementMethod(new ScrollingMovementMethod());**
</RelativeLayout>
</ankit.inventory.ankitarora.inventorymanagementsimple.CustomScrollView>
It worked for my case.
Instead of using this
as the accepted answer suggests, use $parent
instead. So in your partial1.html
you'll have:
<form ng-submit="$parent.addLine()">
<input type="text" ng-model="$parent.lineText" size="30" placeholder="Type your message here">
</form>
If you want to learn more about the scope in ng-include
or other directives, check this out: https://github.com/angular/angular.js/wiki/Understanding-Scopes#ng-include
If you're just quickly looking to keep a cmd instance open instead of exiting immediately, simply doing the following is enough
set /p asd="Hit enter to continue"
at the end of your script and it'll keep the window open.
Note that this'll set asd
as an environment variable, and can be replaced with anything else.
It means the address you are trying to bind the server to is in use. Try another port or close the program using that port.
it's the same as think the next:
"starting with i = 0, while i is less than 8, and adding one to i at the end of the parenthesis, do the instructions between brackets"
It's also the same as:
while( i < 8 )
{
// instrucctions like:
Console.WriteLine(i);
i++;
}
the For sentences is a basis of coding, and it's as useful as necessary its understanding.
It's the way to repeat n-times the same instrucction, or browse ( or do something with each element) an array
Just want to add to Ben's answer on drop_duplicates:
keep
: {‘first’, ‘last’, False}, default ‘first’
first : Drop duplicates except for the first occurrence.
last : Drop duplicates except for the last occurrence.
False : Drop all duplicates.
So setting keep
to False will give you desired answer.
DataFrame.drop_duplicates(*args, **kwargs) Return DataFrame with duplicate rows removed, optionally only considering certain columns
Parameters: subset : column label or sequence of labels, optional Only consider certain columns for identifying duplicates, by default use all of the columns keep : {‘first’, ‘last’, False}, default ‘first’ first : Drop duplicates except for the first occurrence. last : Drop duplicates except for the last occurrence. False : Drop all duplicates. take_last : deprecated inplace : boolean, default False Whether to drop duplicates in place or to return a copy cols : kwargs only argument of subset [deprecated] Returns: deduplicated : DataFrame
document.cookie = "cookiename=Some Name; path=/";

If you want to stringify an HTML element in order to pass it somewhere and parse it back to an element try by creating a unique query for the element:
// 'e' is a circular object that can't be stringify
var e = document.getElementById('MyElement')
// now 'e_str' is a unique query for this element that can be stringify
var e_str = e.tagName
+ ( e.id != "" ? "#" + e.id : "")
+ ( e.className != "" ? "." + e.className.replace(' ','.') : "");
//now you can stringify your element to JSON string
var e_json = JSON.stringify({
'element': e_str
})
than
//parse it back to an object
var obj = JSON.parse( e_json )
//finally connect the 'obj.element' varible to it's element
obj.element = document.querySelector( obj.element )
//now the 'obj.element' is the actual element and you can click it for example:
obj.element.click();
As for the people who are still visiting this page, you are only allowed to close a tab that is opened by a script OR by using the anchor tag of HTML with target _blank. Both those can be closed using the
<script>
window.close();
</script>
you can split using a third party software http://www.hjsplit.org/, for example give yours input that could be upto 9GB and then split, in my case I split 10 MB each
I had the same issue. Tried all the above and found I also had to delete everything inside {PROJECT_ROOT}\bin\Release\netcoreapp2.2 and {PROJECT_ROOT}\obj\Release\netcoreapp2.2 for my project. Its definitely releated to publishing because although I use Deployment tools / bitbucket on my Azure Web App, I did try the Build >> Publish >> Publish to Azure because I wanted to inspect which files were actually deployed.
I don't know much about HTML and CSS design strategies, but if you're looking for something simple and that will fit the screen automatically (as I am) I believe the most straight forward solution is to make the divs behave as words in a paragraph. Try specifying display: inline-block
<div style="display: inline-block">
Content in column A
</div>
<div style="display: inline-block">
Content in column B
</div>
You might or might not need to specify the width of the DIVs
Well, if you know where your user lives in the AD hierarchy (e.g. quite possibly in the "Users" container, if it's a small network), you could also bind to the user account directly, instead of searching for it.
DirectoryEntry deUser = new DirectoryEntry("LDAP://cn=John Doe,cn=Users,dc=yourdomain,dc=com");
if (deUser != null)
{
... do something with your user
}
And if you're on .NET 3.5 already, you could even use the vastly expanded System.DirectorySrevices.AccountManagement namespace with strongly typed classes for each of the most common AD objects:
// bind to your domain
PrincipalContext pc = new PrincipalContext(ContextType.Domain, "LDAP://dc=yourdomain,dc=com");
// find the user by identity (or many other ways)
UserPrincipal user = UserPrincipal.FindByIdentity(pc, "cn=John Doe");
There's loads of information out there on System.DirectoryServices.AccountManagement - check out this excellent article on MSDN by Joe Kaplan and Ethan Wilansky on the topic.

You can use chr() and ord() to convert betweeen letters and int numbers.
Here is a simple example.
>>> chr(97)
'a'
>>> ord('a')
97
"How do I for example read a 3 bit integer value starting at the second bit?"
int number = // whatever;
uint8_t val; // uint8_t is the smallest data type capable of holding 3 bits
val = (number & (1 << 2 | 1 << 3 | 1 << 4)) >> 2;
(I assumed that "second bit" is bit #2, i. e. the third bit really.)
Well in general:
List<String> names = new ArrayList<String>();
names.add("john");
names.add("ann");
String[] namesArr = new String[names.size()];
for (int i = 0; i < names.size(); i++) {
namesArr[i] = names.get(i);
}
Or better yet, using built in:
List<String> names = new ArrayList<String>();
String[] namesArr = names.toArray(new String[names.size()]);
This may be helpful
byte[] bytes = System.Convert.FromBase64String(stringInBase64);
According to React's Documentation, you can write comments in JSX like so:
One-line Comment:
<div>
{/* Comment goes here */}
Hello, {name}!
</div>
Multi-line Comments:
<div>
{/* It also works
for multi-line comments. */}
Hello, {name}!
</div>
Don't forget that you can treat pointers as iterators:
w_.assign(w, w + len);
App Engine is a Platform-as-a-Service. It means that you simply deploy your code, and the platform does everything else for you. For example, if your app becomes very successful, App Engine will automatically create more instances to handle the increased volume.
Compute Engine is an Infrastructure-as-a-Service. You have to create and configure your own virtual machine instances. It gives you more flexibility and generally costs much less than App Engine. The drawback is that you have to manage your app and virtual machines yourself.
Read more about Compute Engine
You can mix both App Engine and Compute Engine, if necessary. They both work well with the other parts of the Google Cloud Platform.
EDIT (May 2016):
One more important distinction: projects running on App Engine can scale down to zero instances if no requests are coming in. This is extremely useful at the development stage as you can go for weeks without going over the generous free quota of instance-hours. Flexible runtime (i.e. "managed VMs") require at least one instance to run constantly.
EDIT (April 2017):
Cloud Functions (currently in beta) is the next level up from App Engine in terms of abstraction - no instances! It allows developers to deploy bite-size pieces of code that execute in response to different events, which may include HTTP requests, changes in Cloud Storage, etc.
The biggest difference with App Engine is that functions are priced per 100 milliseconds, while App Engine's instances shut down only after 15 minutes of inactivity. Another advantage is that Cloud Functions execute immediately, while a call to App Engine may require a new instance - and cold-starting a new instance may take a few seconds or longer (depending on runtime and your code).
This makes Cloud Functions ideal for (a) rare calls - no need to keep an instance live just in case something happens, (b) rapidly changing loads where instances are often spinning and shutting down, and possibly more use cases.

As of version 0.8.6 of Android Studio generating an APK file (signed and I believe unsigned, too) will be placed inside ProjectName/device/build/outputs/apk

There are a couple of issues with the above solutions. If you are using, for example, a UISplitViewController
, the master view will always return true for
if(viewController.isViewLoaded && viewController.view.window) {
//Always true for master view in split view controller
}
Instead, take this simple approach which seems to work well in most, if not all cases:
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
//We are now invisible
self.visible = false;
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
//We are now visible
self.visible = true;
}

It is possible to insert an image in a Google Spreadsheet using Google Apps Script. However, the image should have been hosted publicly over internet. At present, it is not possible to insert private images from Google Drive.
You can use following code to insert an image through script.
function insertImageOnSpreadsheet() {
var SPREADSHEET_URL = 'INSERT_SPREADSHEET_URL_HERE';
// Name of the specific sheet in the spreadsheet.
var SHEET_NAME = 'INSERT_SHEET_NAME_HERE';
var ss = SpreadsheetApp.openByUrl(SPREADSHEET_URL);
var sheet = ss.getSheetByName(SHEET_NAME);
var response = UrlFetchApp.fetch(
'https://developers.google.com/adwords/scripts/images/reports.png');
var binaryData = response.getContent();
// Insert the image in cell A1.
var blob = Utilities.newBlob(binaryData, 'image/png', 'MyImageName');
sheet.insertImage(blob, 1, 1);
}
Above example has been copied from this link. Check noogui's reply for details.
In case you need to insert image from Google Drive, please check this link for current updates.
There's no point in declaring the class as static
. Just declare its methods static
and call them from the class name as normal, like Java's Math class.
Also, even though it isn't strictly necessary to make the constructor private, it is a good idea to do so. Marking the constructor private prevents other people from creating instances of your class, then calling static methods from those instances. (These calls work exactly the same in Java, they're just misleading and hurt the readability of your code.)
Don’t use the DOM to do this. Using the DOM to decode HTML entities (as suggested in the currently accepted answer) leads to differences in cross-browser results.
For a robust & deterministic solution that decodes character references according to the algorithm in the HTML Standard, use the he library. From its README:
he (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. It supports all standardized named character references as per HTML, handles ambiguous ampersands and other edge cases just like a browser would, has an extensive test suite, and — contrary to many other JavaScript solutions — he handles astral Unicode symbols just fine. An online demo is available.
Here’s how you’d use it:
he.decode("We're unable to complete your request at this time.");
? "We're unable to complete your request at this time."
Disclaimer: I'm the author of the he library.
See this Stack Overflow answer for some more info.
DateTimeFormat
, introduced in java 8:The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.
Your input format looks quite standard, except the trailing Z
. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
. The trailing 'Z'
is the interesting part. Usually there's time zone data here, like -0700
. So the pattern would be ...Z
, i.e. without apostrophes.
The output format is way more simple: "dd-MM-yyyy"
. Mind the small y
-s.
Here is the example code:
DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018
SimpleDateFormat
SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018
A personal example using mysql 5.5: I had an inner join between 2 tables, one of 3 million rows and one of 10 thousand rows.
When using a like on an index as below(no wildcards), it took about 30 seconds:
where login like '12345678'
using 'explain' I get:
When using an '=' on the same query, it took about 0.1 seconds:
where login ='600009'
Using 'explain' I get:
As you can see, the like
completely cancelled the index seek, so query took 300 times more time.

SQL Server allows you to join tables from different databases as long as those databases are on the same server. The join syntax is the same; the only difference is that you must fully specify table names.
Let's suppose you have two databases on the same server - Db1
and Db2
. Db1
has a table called Clients
with a column ClientId
and Db2
has a table called Messages
with a column ClientId
(let's leave asside why those tables are in different databases).
Now, to perform a join on the above-mentioned tables you will be using this query:
select *
from Db1.dbo.Clients c
join Db2.dbo.Messages m on c.ClientId = m.ClientId
Update: this was fixed in Firefox v35. See the full gist for details.
== how to hide the select arrow in Firefox ==
Just figured out how to do it. The trick is to use a mix of -prefix-appearance
, text-indent
and text-overflow
. It is pure CSS and requires no extra markup.
select {
-moz-appearance: none;
text-indent: 0.01px;
text-overflow: '';
}
Long story short, by pushing it a tiny bit to the right, the overflow gets rid of the arrow. Pretty neat, huh?
More details on this gist I just wrote. Tested on Ubuntu, Mac and Windows, all with recent Firefox versions.
And what does "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.5 Safari/535.19" means ?
This is the value of User-Agent, the browser identification string.
For this reason, most Web browsers use a User-Agent string value as follows:
Mozilla/[version] ([system and browser information]) [platform] ([platform details]) [extensions]. For example, Safari on the iPad has used the following:
Mozilla/5.0 (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Mobile/7B405 The components of this string are as follows:
Mozilla/5.0: Previously used to indicate compatibility with the Mozilla rendering engine. (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us): Details of the system in which the browser is running. AppleWebKit/531.21.10: The platform the browser uses. (KHTML, like Gecko): Browser platform details. Mobile/7B405: This is used by the browser to indicate specific enhancements that are available directly in the browser or through third parties. An example of this is Microsoft Live Meeting which registers an extension so that the Live Meeting service knows if the software is already installed, which means it can provide a streamlined experience to joining meetings.
This value will be used to identify what browser is being used by end user.
Here's a guided approach.
Your authentication service issues a JWT token that is signed using a secret that is also available in your API service. The reason they need to be there too is that you will need to verify the tokens received to make sure you created them. The nice thing about JWTs is that their payload can hold claims as to what the user is authorised to access should different users have different access control levels.
That architecture renders authentication stateless: No need to store any tokens in a database unless you would like to handle token blacklisting (think banning users). Being stateless is crucial if you ever need to scale. That also frees up your API service from having to call the authentication server at all as the information they need for both authentication and authorisation are in the issued token.
Flow (no refresh tokens):
There are a couple of issues here. Namely, that auth token in the wrong hands provides unlimited access to a malicious user to pretend they are the affected user and call your APIs indefinitely. To handle that, tokens have an expiry date and clients are forced to request new tokens whenever expiry happens. That expiry is part of the token's payload. But if tokens are short-lived, do we require users to authenticate with their usernames and password every time? No. We do not want to ask a user for their password every 30min to an hour, and we do not want to persist that password anywhere in the client. To get around that issue, we introduce the concept of refresh tokens. They are longer lived tokens that serve one purpose: act as a user's password, authenticate them to get a new token. Downside is that with this architecture your authentication server needs to persist these refresh token in a database.
New flow (with refresh tokens):
OPTIONAL (banning users)
How do we ban users? Using that model there is no easy way to do so. Enhancement: Every persisted refresh token includes a blacklisted field and only issue new tokens if the refresh token isn't black listed.
Things to consider:
npm install --save-dev "cross-env"
module.cross-env NODE_ENV=development node foo.js
.
Then you can run the like npm run build
.I have been experiencing this problem for the last week now as I've been trying to send DELETE requests to my PHP server through AJAX. I recently upgraded my hosting plan where I now have an SSL Certificate on my host which stores the PHP and JS files. Since adding an SSL Certificate I no longer experience this issue. Hoping this helps with this strange error.
To get the date to show as the current time zone I used the following.
if let timeResult = (jsonResult["dt"] as? Double) {
let date = NSDate(timeIntervalSince1970: timeResult)
let dateFormatter = NSDateFormatter()
dateFormatter.timeStyle = NSDateFormatterStyle.MediumStyle //Set time style
dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle //Set date style
dateFormatter.timeZone = NSTimeZone()
let localDate = dateFormatter.stringFromDate(date)
}
Swift 3.0 Version
if let timeResult = (jsonResult["dt"] as? Double) {
let date = Date(timeIntervalSince1970: timeResult)
let dateFormatter = DateFormatter()
dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
dateFormatter.timeZone = self.timeZone
let localDate = dateFormatter.string(from: date)
}
Swift 5
if let timeResult = (jsonResult["dt"] as? Double) {
let date = Date(timeIntervalSince1970: timeResult)
let dateFormatter = DateFormatter()
dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
dateFormatter.timeZone = .current
let localDate = dateFormatter.string(from: date)
}
I had the same problem and I got to solve with this code:
ALTER TABLE `table_name` DROP FOREIGN KEY `id_name_fk`;
ALTER TABLE `table_name` DROP INDEX `id_name_fk`;

Here's my full code on mac, hope this helps someone. All my csv files are saved in /Users/lionelyu/Documents/Python/Python Projects/
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
plt.style.use('ggplot')
path = '/Users/lionelyu/Documents/Python/Python Projects/'
aapl = pd.read_csv(path + 'AAPL_CLOSE.csv',index_col='Date',parse_dates=True)
cisco = pd.read_csv(path + 'CISCO_CLOSE.csv',index_col='Date',parse_dates=True)
ibm = pd.read_csv(path + 'IBM_CLOSE.csv',index_col='Date',parse_dates=True)
amzn = pd.read_csv(path + 'AMZN_CLOSE.csv',index_col='Date',parse_dates=True)
Do you want more space between paragraphs? Then you can change the parameter \parskip
.
For example, try
\setlength{\parskip}{10pt plus 1pt minus 1pt}
This means that the space between paragraphs is usually 10pt, but can grow or shrink by up to 1pt. This means you give LaTeX the ability to change it up to one 1pt in order to achieve a better page layout. You can remove the plus and minus parts to make it always your specified length.
