I agree that having to query the SecurityContext for the current user stinks, it seems a very un-Spring way to handle this problem.
I wrote a static "helper" class to deal with this problem; it's dirty in that it's a global and static method, but I figured this way if we change anything related to Security, at least I only have to change the details in one place:
/**
* Returns the domain User object for the currently logged in user, or null
* if no User is logged in.
*
* @return User object for the currently logged in user, or null if no User
* is logged in.
*/
public static User getCurrentUser() {
Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal()
if (principal instanceof MyUserDetails) return ((MyUserDetails) principal).getUser();
// principal object is either null or represents anonymous user -
// neither of which our domain User object can represent - so return null
return null;
}
/**
* Utility method to determine if the current user is logged in /
* authenticated.
* <p>
* Equivalent of calling:
* <p>
* <code>getCurrentUser() != null</code>
*
* @return if user is logged in
*/
public static boolean isLoggedIn() {
return getCurrentUser() != null;
}
You can use a generator expression:
tuple(i for i in (1, 2, 3))
but parentheses were already taken for … generator expressions.
To distinguish them intuitively
l1 = ['a', 'b', 'c']
l2 = ['d', 'e', 'f']
l1.append(l2)
l1
['a', 'b', 'c', ['d', 'e', 'f']]
It's like l1
reproduce a body inside her body(nested).
# Reset l1 = ['a', 'b', 'c']
l1.extend(l2)
l1
['a', 'b', 'c', 'd', 'e', 'f']
It's like that two separated individuals get married and construct an united family.
Besides I make an exhaustive cheatsheet of all list's methods for your reference.
list_methods = {'Add': {'extend', 'append', 'insert'},
'Remove': {'pop', 'remove', 'clear'}
'Sort': {'reverse', 'sort'},
'Search': {'count', 'index'},
'Copy': {'copy'},
}
I had a case where I'm pretty sure that my code would run smoothly. But still, got an error and I checked the Javascript console of Google Chrome to check what it is.
My error line is
opt.SetAttribute("value",values[a]);
And got the same error message:
Uncaught TypeError: undefined is not a function
Nothing seems wrong with the code above but it was not running. I troubleshoot for almost an hour and then compared it with my other running code. My error is that it was set to SetAttribute
, which should be setAttribute
.
The best way to set/get the value of a textarea is the .val()
, .value
method.
.text()
internally uses the .textContent
(or .innerText
for IE) method to get the contents of a <textarea>
. The following test cases illustrate how text()
and .val()
relate to each other:
var t = '<textarea>';
console.log($(t).text('test').val()); // Prints test
console.log($(t).val('too').text('test').val()); // Prints too
console.log($(t).val('too').text()); // Prints nothing
console.log($(t).text('test').val('too').val()); // Prints too
console.log($(t).text('test').val('too').text()); // Prints test
The value
property, used by .val()
always shows the current visible value, whereas text()
's return value can be wrong.
git log --oneline --decorate --all --graph
A visual tree with branch names included.
Use this to add it as an alias
git config --global alias.tree "log --oneline --decorate --all --graph"
You call it with
git tree
malloc will do.
int rows = 20;
int cols = 20;
int *array;
array = malloc(rows * cols * sizeof(int));

You are testing if the values of the variables error
and Already
are present in RepoOutput[RepoName.index(repo)]
. If these variables don't exist then an undefined object is used.
Both of your if
and elif
tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].
I think you wanted to test if certain strings are in the value instead:
{% if "error" in RepoOutput[RepoName.index(repo)] %}
<td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
<td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
<td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>
Other corrections I made:
{% elif ... %}
instead of {$ elif ... %}
.</tr>
tag out of the if
conditional structure, it needs to be there always.id
attributeNote that most likely you want to use a class
attribute instead here, not an id
, the latter must have a value that must be unique across your HTML document.
Personally, I'd set the class value here and reduce the duplication a little:
{% if "Already" in RepoOutput[RepoName.index(repo)] %}
{% set row_class = "good" %}
{% else %}
{% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>
An alternative to using keytool
, you can use the command
openssl x509 -in certificate.pem -text
This should work for any x509 .pem file provided you have openssl
installed.
This depends on the database server, but it is often called something like CEIL
or CEILING
. For example, in MySQL...
mysql> select ceil(10.5);
+------------+
| ceil(10.5) |
+------------+
| 11 |
+------------+
You can then do UPDATE PRODUCT SET price=CEIL(some_other_field);
So..it was SSL problem. Whatever I was doing was absolutely correct. Only that I was not using the ssl option. So I added "-Usessl true" to my original command and it worked.
Specify the buildpack while creating the app.

There are many metrics to define similarity and distance between strings as mentioned above. I will give my 5 cents by showing an example of Jaccard similarity
with Q-Grams
and an example with edit distance
.
The libraries
from nltk.metrics.distance import jaccard_distance
from nltk.util import ngrams
from nltk.metrics.distance import edit_distance
Jaccard Similarity
1-jaccard_distance(set(ngrams('Apple', 2)), set(ngrams('Appel', 2)))
and we get:
0.33333333333333337
And for the Apple
and Mango
1-jaccard_distance(set(ngrams('Apple', 2)), set(ngrams('Mango', 2)))
and we get:
0.0
Edit Distance
edit_distance('Apple', 'Appel')
and we get:
2
And finally,
edit_distance('Apple', 'Mango')
and we get:
5
Cosine Similarity on Q-Grams (q=2)
Another solution is to work with the textdistance
library. I will provide an example of Cosine Similarity
import textdistance
1-textdistance.Cosine(qval=2).distance('Apple', 'Appel')
and we get:
0.5
An alternative to using environment variables, which can get messy if you have a lot of them, is to use volumes to make a directory on the host accessible in the container.
If you put all your credentials as files in that folder, then the container can read the files and use them as it pleases.
For example:
$ echo "secret" > /root/configs/password.txt
$ docker run -v /root/configs:/cfg ...
In the Docker container:
# echo Password is `cat /cfg/password.txt`
Password is secret
Many programs can read their credentials from a separate file, so this way you can just point the program to one of the files.
You may give a shot at using itoa. Another alternative is to use sprintf.
Another solutions using vim (just for reference).
Solution 1:
Open file in vim vim filename
, then execute command :% normal Jj
This command is very easy to understand:
After that, save the file and exit with :wq
Solution 2:
Execute the command in shell, vim -c ":% normal Jj" filename
, then save the file and exit with :wq
.
Sets behave different than dicts, you need to use set operations like issubset():
>>> k
{'ip': '123.123.123.123', 'pw': 'test1234', 'port': 1234, 'debug': True}
>>> set('ip,port,pw'.split(',')).issubset(set(k.keys()))
True
>>> set('ip,port,pw'.split(',')) in set(k.keys())
False
What I did was creating my own Window and Style. Because I like to have control over everything and I didn't want some external libraries just to use a Window from it. I looked at already mentioned MahApps.Metro on GitHub
and also very nice Modern UI on GitHub. (.NET4.5 only)
There is one more it's Elysium but I really didn't try this one.
The style I did was really easy when I looked how it's done in these. Now I have my own Window and I can do whatever I want with xaml... for me it's the main reason why I did my own. And I made one more for you too :) I should probably say that I wouldn't be able to do it without exploring Modern UI it was great help. I tried to make it look like VS2012 Window. It looks like this.
Here is code (please note that it's targeting .NET4.5)
public class MyWindow : Window
{
public MyWindow()
{
this.CommandBindings.Add(new CommandBinding(SystemCommands.CloseWindowCommand, this.OnCloseWindow));
this.CommandBindings.Add(new CommandBinding(SystemCommands.MaximizeWindowCommand, this.OnMaximizeWindow, this.OnCanResizeWindow));
this.CommandBindings.Add(new CommandBinding(SystemCommands.MinimizeWindowCommand, this.OnMinimizeWindow, this.OnCanMinimizeWindow));
this.CommandBindings.Add(new CommandBinding(SystemCommands.RestoreWindowCommand, this.OnRestoreWindow, this.OnCanResizeWindow));
}
private void OnCanResizeWindow(object sender, CanExecuteRoutedEventArgs e)
{
e.CanExecute = this.ResizeMode == ResizeMode.CanResize || this.ResizeMode == ResizeMode.CanResizeWithGrip;
}
private void OnCanMinimizeWindow(object sender, CanExecuteRoutedEventArgs e)
{
e.CanExecute = this.ResizeMode != ResizeMode.NoResize;
}
private void OnCloseWindow(object target, ExecutedRoutedEventArgs e)
{
SystemCommands.CloseWindow(this);
}
private void OnMaximizeWindow(object target, ExecutedRoutedEventArgs e)
{
SystemCommands.MaximizeWindow(this);
}
private void OnMinimizeWindow(object target, ExecutedRoutedEventArgs e)
{
SystemCommands.MinimizeWindow(this);
}
private void OnRestoreWindow(object target, ExecutedRoutedEventArgs e)
{
SystemCommands.RestoreWindow(this);
}
}

I'd like to add df.values.tolist()
. (as long as you don't mind to get a column of lists rather than tuples)
import pandas as pd
import numpy as np
size = int(1e+07)
df = pd.DataFrame({'a': np.random.rand(size), 'b': np.random.rand(size)})
%timeit df.values.tolist()
1.47 s ± 38.9 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
%timeit list(zip(df.a,df.b))
1.92 s ± 131 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
You can either
TextView
by a ScrollView
; orScrollingMovementMethod.getInstance();
.Different web stacks do support different lengths of http-requests. I know from experience that the early stacks of Safari only supported 4000 characters and thus had difficulty handling ASP.net pages because of the USER-STATE. This is even for POST, so you would have to check the browser and see what the stack limit is. I think that you may reach a limit even on newer browsers. I cannot remember but one of them (IE6, I think) had a limit of 16-bit limit, 32,768 or something.
I totally missed the export button at the bottom of each visualization. As for read only access...Shield from Elasticsearch might be worth exploring.
Sorry for my bad English. Checking Mails using Python with MAPI is easier,
outlook =win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
folder = outlook.Folders[5]
Subfldr = folder.Folders[5]
messages_REACH = Subfldr.Items
message = messages_REACH.GetFirst()
Here we can get the most first mail into the Mail box, or into any sub folder. Actually, we need to check the Mailbox number & orientation. With the help of this analysis we can check each mailbox & its sub mailbox folders.
Similarly please find the below code, where we can see, the last/ earlier mails. How we need to check.
`outlook =win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
folder = outlook.Folders[5]
Subfldr = folder.Folders[5]
messages_REACH = Subfldr.Items
message = messages_REACH.GetLast()`
With this we can get most recent email into the mailbox. According to the above mentioned code, we can check our all mail boxes, & its sub folders.
This will only work if you want to compare exact strings. It will not work in case you want to check if the column string contains any of the strings in the list.
The right way to compare with a list would be :
searchfor = ['john', 'doe']
df = df[~df.col.str.contains('|'.join(searchfor))]
I use this:

Simple code for dynamic array. In below code then array will become full of size we copy all element to new double size array(variable size array).sample code is below
public class DynamicArray {
static int []increaseSizeOfArray(int []arr){
int []brr=new int[(arr.length*2)];
for (int i = 0; i < arr.length; i++) {
brr[i]=arr[i];
}
return brr;
}
public static void main(String[] args) {
int []arr=new int[5];
for (int i = 0; i < 11; i++) {
if (i<arr.length) {
arr[i]=i+100;
}
else {
arr=increaseSizeOfArray(arr);
arr[i]=i+100;
}
}
for (int i = 0; i < arr.length; i++) {
System.out.println("arr="+arr[i]);
}
}
}
Source : How to make dynamic array
std::vector<double>::assign
is the way to go, because it's little code. But how does it work, actually? Doesnt't it resize and then copy? In MS implementation of STL I am using it does exactly so.
I'm afraid there's no faster way to implement (re)initializing your std::vector
.
$articles =DB::table('articles')
->join('categories','articles.id', '=', 'categories.id')
->join('user', 'articles.user_id', '=', 'user.id')
->select('articles.id','articles.title','articles.body','user.user_name', 'categories.category_name')
->get();
return view('myarticlesview',['articles'=>$articles]);
Maybe this simple solution can help:
<input type="text" id="myInput" value="No War"/><button onclick="document.getElementById('myInput').value = ''" title="Clear">X</button></input>

First of all, have only one id="test"
Secondly, try this:
if ($('[name="test"]').is(':checked'))
Many different ways to do it...
One third party service you could use is http://ipinfodb.com. They provide hostname, geolocation and additional information.
Register for an API key here: http://ipinfodb.com/register.php. This will allow you to retrieve results from their server, without this it will not work.
Copy and past the following PHP code:
$ipaddress = $_SERVER['REMOTE_ADDR'];
$api_key = 'YOUR_API_KEY_HERE';
$data = file_get_contents("http://api.ipinfodb.com/v3/ip-city/?key=$api_key&ip=$ipaddress&format=json");
$data = json_decode($data);
$country = $data['Country'];
Downside:
Quoting from their website:
Our free API is using IP2Location Lite version which provides lower accuracy.
This function will return country name using the http://www.netip.de/ service.
$ipaddress = $_SERVER['REMOTE_ADDR'];
function geoCheckIP($ip)
{
$response=@file_get_contents('http://www.netip.de/search?query='.$ip);
$patterns=array();
$patterns["country"] = '#Country: (.*?) #i';
$ipInfo=array();
foreach ($patterns as $key => $pattern)
{
$ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : 'not found';
}
return $ipInfo;
}
print_r(geoCheckIP($ipaddress));
Output:
Array ( [country] => DE - Germany ) // Full Country Name
If you want the name, use Martin's method. If you want to know whether it's an instance of a certain class:
boolean b = a instanceof String
@Html.ActionLink("display name", "action", "Contorller"
new { id = 1 },Html Attribute=new {Attribute1="value"})
Try this
<script>
$().ready(function(){
$('.coupon_question').live('click',function()
{
if ($('.coupon_question').is(':checked')) {
$(".answer").show();
} else {
$(".answer").hide();
}
});
});
</script>
You can use the find function:
if($('#popup').find('p.filled-text').length !== 0)
// Do Stuff
Yes, it's possible to use inline if-expressions:
{{ 'Update' if files else 'Continue' }}
You could put it in a function.
String paramStr = "a parameter";
Runnable myRunnable = createRunnable(paramStr);
private Runnable createRunnable(final String paramStr){
Runnable aRunnable = new Runnable(){
public void run(){
someFunc(paramStr);
}
};
return aRunnable;
}
(When I used this, my parameter was an integer ID, which I used to make a hashmap of ID --> myRunnables. That way, I can use the hashmap to post/remove different myRunnable objects in a handler.)
According to @Abhishek Singh's you need to understand the problem:
What is the line which gives exception ?? The reason for this is because the element to which you have referred is removed from the DOM structure
and you can not refer to it anymore (imagine what element's ID has changed).
Follow the code:
class TogglingPage {
@FindBy(...)
private WebElement btnTurnOff;
@FindBy(...)
private WebElement btnTurnOn;
TogglingPage turnOff() {
this.btnTurnOff.isDisplayed();
this.btnTurnOff.click(); // when clicked, button should swap into btnTurnOn
this.btnTurnOn.isDisplayed();
this.btnTurnOn.click(); // when clicked, button should swap into btnTurnOff
this.btnTurnOff.isDisplayed(); // throws an exception
return new TogglingPage();
}
}
Now, let us wonder why?
btnTurnOff
was found by a driver - okbtnTurnOff
was replaced by btnTurnOn
- okbtnTurnOn
was found by a driver. - okbtnTurnOn
was replaced by btnTurnOff
- okthis.btnTurnOff.isDisplayed();
on the element which does not exist anymore in Selenium sense - you can see it, it works perfectly, but it is a different instance of the same button. Possible fix:
TogglingPage turnOff() {
this.btnTurnOff.isDisplayed();
this.btnTurnOff.click();
TogglingPage newPage = new TogglingPage();
newPage.btnTurnOn.isDisplayed();
newPage.btnTurnOn.click();
TogglingPage newerPage = new TogglingPage();
newerPage.btnTurnOff.isDisplayed(); // ok
return newerPage;
}

For anyone who comes here, as I did, looking for the syntax to change origin to a different location you can find that documentation here: https://help.github.com/articles/changing-a-remote-s-url/. Using git remote add
to do this will result in "fatal: remote origin already exists."
Nutshell:
git remote set-url origin https://github.com/username/repo
(The marked answer is correct, I'm just hoping to help anyone as lost as I was... haha)
There are already nice solution has been given. The below code can help others to query over datatable and get the value of each row of the datatable for the ImagePath column.

Example:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="key" value="test" />
</appSettings>
</configuration>
You can access the configurations by using ConfigurationManager
as shown in the piece of code snippet below:
var value = System.Configuration.ConfigurationManager.AppSettings["key"];
// value is now "test"
Note: ConfigurationSettings
is obsolete method to retrieve configuration information.
var value = System.Configuration.ConfigurationSettings.AppSettings["key"];
For saving use this :
[[NSUserDefaults standardUserDefaults]setObject:@"YES" forKey:@"KTerminated"];
[[NSUserDefaults standardUserDefaults]synchronize];
For Retriveing use this :
[[[NSUserDefaults standardUserDefaults]stringForKey:@"KTerminated"] isEqualToString:@"YES"];

1 line will do all
For message queue
ipcs -q | sed "$ d; 1,2d" | awk '{ print "Removing " $2; system("ipcrm -q " $2) }'
ipcs -q
will give the records of message queues
sed "$ d; 1,2d "
will remove last blank line ("$ d"
) and first two header lines ("1,2d"
)
awk
will do the rest i.e. printing and removing using command "ipcrm -q"
w.r.t. the value of column 2 (coz $2
)
Another alternative, assuming your elements are stored as variables (which is often a good idea if you're accessing them multiple times in a function body):
function disableMinHeight() {
var $html = $("html");
var $body = $("body");
var $slideout = $("#slideout");
$html.add($body).add($slideout).css("min-height", 0);
};
Takes advantage of jQuery chaining and allows you to use references.
Teylyn's answer worked great for me, but I had to modify it a bit to get proper results. I want to provide an extended explanation for whoever would need it.
My setup was as follows:
I put the following formula in cell A1 of Sheet3:
=iferror(vlookup(Sheet1!A$1;Sheet2!$A$1:$D$50;column(A1);false);Sheet1!A1)
Read this as follows: Take the value of the first column in Sheet1 (old data). Look up in Sheet2 (updated rows). If present, output the value from the indicated column in Sheet2. On error, output the value for the current column of Sheet1.
Notes:
In my version of the formula, ";" is used as parameter separator instead of ",". That is because I am located in Europe and we use the "," as decimal separator. Change ";" back to "," if you live in a country where "." is the decimal separator.
A$1: means always take column 1 when copying the formula to a cell in a different column. $A$1 means: always take the exact cell A1, even when copying the formula to a different row or column.
After pasting the formula in A1, I extended the range to columns B, C, etc., until the full width of my table was reached. Because of the $-signs used, this gives the following formula's in cells B1, C1, etc.:
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(B1);FALSE);'Sheet1'!B1)
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(C1);FALSE);'Sheet1'!C1)
and so forth. Note that the lookup is still done in the first column. This is because VLOOKUP needs the lookup data to be sorted on the column where the lookup is done. The output column is however the column where the formula is pasted.
Next, select a rectangle in Sheet 3 starting at A1 and having the size of the data in Sheet1 (same number of rows and columns). Press Ctrl-D to copy the formulas of the first row to all selected cells.
Cells A2, A3, etc. will get these formulas:
=IFERROR(VLOOKUP('Sheet1'!$A2;'Sheet2'!$A$1:$D$50;COLUMN(A2);FALSE);'Sheet1'!A2)
=IFERROR(VLOOKUP('Sheet1'!$A3;'Sheet2'!$A$1:$D$50;COLUMN(A3);FALSE);'Sheet1'!A3)
Because of the use of $-signs, the lookup area is constant, but input data is used from the current row.
Need to do normal
forever start script.js
to start, and to check console/error logs use
forever logs
this will print list of all logs being stored by forever
and then you can use tail -f /path/to/logs/file.log
and this will print live logs to your window. hit ctrl+z to stop logs print.
$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");
Your data.frame mat
is rectangular (n_rows!= n_cols).
Therefore, you cannot make a data.frame
out of the column- and rownames, because each column in a data.frame must be the same length.
Maybe this suffices your needs:
require(reshape2)
mat$id <- rownames(mat)
melt(mat)
One quick and dirty way is to set the build context up as many levels as you need - but this can have consequences. If you're working in a microservices architecture that looks like this:
./Code/Repo1
./Code/Repo2
...
You can set the build context to the parent Code
directory and then access everything, but it turns out that with a large number of repositories, this can result in the build taking a long time.
An example situation could be that another team maintains a database schema in Repo1
and your team's code in Repo2
depends on this. You want to dockerise this dependency with some of your own seed data without worrying about schema changes or polluting the other team's repository (depending on what the changes are you may still have to change your seed data scripts of course)
The second approach is hacky but gets around the issue of long builds:
Create a sh (or ps1) script in ./Code/Repo2
to copy the files you need and invoke the docker commands you want, for example:
#!/bin/bash
rm -r ./db/schema
mkdir ./db/schema
cp -r ../Repo1/db/schema ./db/schema
docker-compose -f docker-compose.yml down
docker container prune -f
docker-compose -f docker-compose.yml up --build
In the docker-compose file, simply set the context as Repo2
root and use the content of the ./db/schema
directory in your dockerfile without worrying about the path.
Bear in mind that you will run the risk of accidentally committing this directory to source control, but scripting cleanup actions should be easy enough.
In case someone would need - to achieve same or similar thing(like delete) via POST
instead of FromUri
, use FromBody
and on client side(JS/jQuery) format param as $.param({ '': categoryids }, true)
c#:
public IHttpActionResult Remove([FromBody] int[] categoryIds)
jQuery:
$.ajax({
type: 'POST',
data: $.param({ '': categoryids }, true),
url: url,
//...
});
The thing with $.param({ '': categoryids }, true)
is that it .net will expect post body to contain urlencoded value like =1&=2&=3
without parameter name, and without brackets.
No, it is not a bug. It is a result of how the ParameterizedTypeReference
hack works.
If you look at its implementation, it uses Class#getGenericSuperclass()
which states
Returns the Type representing the direct superclass of the entity (class, interface, primitive type or void) represented by this Class.
If the superclass is a parameterized type, the
Type
object returned must accurately reflect the actual type parameters used in the source code.
So, if you use
new ParameterizedTypeReference<ResponseWrapper<MyClass>>() {}
it will accurately return a Type
for ResponseWrapper<MyClass>
.
If you use
new ParameterizedTypeReference<ResponseWrapper<T>>() {}
it will accurately return a Type
for ResponseWrapper<T>
because that is how it appears in the source code.
When Spring sees T
, which is actually a TypeVariable
object, it doesn't know the type to use, so it uses its default.
You cannot use ParameterizedTypeReference
the way you are proposing, making it generic in the sense of accepting any type. Consider writing a Map
with key Class
mapped to a predefined ParameterizedTypeReference
for that class.
You can subclass ParameterizedTypeReference
and override its getType
method to return an appropriately created ParameterizedType
, as suggested by IonSpin.
I must cautiously doubt the previously accepted answer that using a DialogFragment is the best option. The intended (primary) purpose of the DialogFragment seems to be to display fragments that are dialogs themselves, not to display fragments that have dialogs to display.
I believe that using the fragment's activity to mediate between the dialog and the fragment is the preferable option.
I know this question is very old, but I was making similar thing in my kotlin app recently. So here is an example if anyone needs it:
val dfs = DecimalFormatSymbols.getInstance(Locale.getDefault())
val bigD = BigDecimal("1e+30")
val formattedBigD = DecimalFormat("#,##0.#",dfs).format(bigD)
Result displaying $formattedBigD:
1,000,000,000,000,000,000,000,000,000,000
The trade off you are getting is that the program runs a wee bit faster. That may be a cold comfort to you during development, but it could matter a great deal once development is complete, and the program is just being run by users.
Add the following css to disable the default scroll:
body {
overflow: hidden;
}
And change the #content
css to this to make the scroll only on content body:
#content {
max-height: calc(100% - 120px);
overflow-y: scroll;
padding: 0px 10%;
margin-top: 60px;
}
Edit:
Actually, I'm not sure what was the issue you were facing, since it seems that your css is working. I have only added the HTML and the header css statement:

If you dont want to change the format of date and time from the timestamp, you can use the explode
function in php
$timestamp = "2012-04-02 02:57:54"
$datetime = explode(" ",$timestamp);
$date = $datetime[0];
$time = $datetime[1];
You can also disable triggers in pgAdmin (III):
Use this. Works fine
input.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);
input.setKeyListener(DigitsKeyListener.getInstance("0123456789"));
EDIT
kotlin version
fun EditText.onlyNumbers() {
inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_DECIMAL or
InputType.TYPE_NUMBER_FLAG_SIGNED
keyListener = DigitsKeyListener.getInstance("0123456789")
}
Try updating the line to:
ocr.Init(@"C:\", "eng", false); // the path here should be the parent folder of tessdata
$(".datepicker").datepicker({maxDate: '0'});
This will set the maxDate to +0 days from the current date (i.e. today). See:
This post aims to give readers a primer on SQL-flavored merging with pandas, how to use it, and when not to use it.
In particular, here's what this post will go through:
The basics - types of joins (LEFT, RIGHT, OUTER, INNER)
What this post (and other posts by me on this thread) will not go through:
Note
Most examples default to INNER JOIN operations while demonstrating various features, unless otherwise specified.Furthermore, all the DataFrames here can be copied and replicated so you can play with them. Also, see this post on how to read DataFrames from your clipboard.
Lastly, all visual representation of JOIN operations have been hand-drawn using Google Drawings. Inspiration from here.
merge
!np.random.seed(0)
left = pd.DataFrame({'key': ['A', 'B', 'C', 'D'], 'value': np.random.randn(4)})
right = pd.DataFrame({'key': ['B', 'D', 'E', 'F'], 'value': np.random.randn(4)})
left
key value
0 A 1.764052
1 B 0.400157
2 C 0.978738
3 D 2.240893
right
key value
0 B 1.867558
1 D -0.977278
2 E 0.950088
3 F -0.151357
For the sake of simplicity, the key column has the same name (for now).
An INNER JOIN is represented by
Note
This, along with the forthcoming figures all follow this convention:
- blue indicates rows that are present in the merge result
- red indicates rows that are excluded from the result (i.e., removed)
- green indicates missing values that are replaced with
NaN
s in the result
To perform an INNER JOIN, call merge
on the left DataFrame, specifying the right DataFrame and the join key (at the very least) as arguments.
left.merge(right, on='key')
# Or, if you want to be explicit
# left.merge(right, on='key', how='inner')
key value_x value_y
0 B 0.400157 1.867558
1 D 2.240893 -0.977278
This returns only rows from left
and right
which share a common key (in this example, "B" and "D).
A LEFT OUTER JOIN, or LEFT JOIN is represented by
This can be performed by specifying how='left'
.
left.merge(right, on='key', how='left')
key value_x value_y
0 A 1.764052 NaN
1 B 0.400157 1.867558
2 C 0.978738 NaN
3 D 2.240893 -0.977278
Carefully note the placement of NaNs here. If you specify how='left'
, then only keys from left
are used, and missing data from right
is replaced by NaN.
And similarly, for a RIGHT OUTER JOIN, or RIGHT JOIN which is...
...specify how='right'
:
left.merge(right, on='key', how='right')
key value_x value_y
0 B 0.400157 1.867558
1 D 2.240893 -0.977278
2 E NaN 0.950088
3 F NaN -0.151357
Here, keys from right
are used, and missing data from left
is replaced by NaN.
Finally, for the FULL OUTER JOIN, given by
specify how='outer'
.
left.merge(right, on='key', how='outer')
key value_x value_y
0 A 1.764052 NaN
1 B 0.400157 1.867558
2 C 0.978738 NaN
3 D 2.240893 -0.977278
4 E NaN 0.950088
5 F NaN -0.151357
This uses the keys from both frames, and NaNs are inserted for missing rows in both.
The documentation summarizes these various merges nicely:
If you need LEFT-Excluding JOINs and RIGHT-Excluding JOINs in two steps.
For LEFT-Excluding JOIN, represented as
Start by performing a LEFT OUTER JOIN and then filtering (excluding!) rows coming from left
only,
(left.merge(right, on='key', how='left', indicator=True)
.query('_merge == "left_only"')
.drop('_merge', 1))
key value_x value_y
0 A 1.764052 NaN
2 C 0.978738 NaN
Where,
left.merge(right, on='key', how='left', indicator=True)
key value_x value_y _merge
0 A 1.764052 NaN left_only
1 B 0.400157 1.867558 both
2 C 0.978738 NaN left_only
3 D 2.240893 -0.977278 both
And similarly, for a RIGHT-Excluding JOIN,
(left.merge(right, on='key', how='right', indicator=True)
.query('_merge == "right_only"')
.drop('_merge', 1))
key value_x value_y
2 E NaN 0.950088
3 F NaN -0.151357
Lastly, if you are required to do a merge that only retains keys from the left or right, but not both (IOW, performing an ANTI-JOIN),
You can do this in similar fashion—
(left.merge(right, on='key', how='outer', indicator=True)
.query('_merge != "both"')
.drop('_merge', 1))
key value_x value_y
0 A 1.764052 NaN
2 C 0.978738 NaN
4 E NaN 0.950088
5 F NaN -0.151357
If the key columns are named differently—for example, left
has keyLeft
, and right
has keyRight
instead of key
—then you will have to specify left_on
and right_on
as arguments instead of on
:
left2 = left.rename({'key':'keyLeft'}, axis=1)
right2 = right.rename({'key':'keyRight'}, axis=1)
left2
keyLeft value
0 A 1.764052
1 B 0.400157
2 C 0.978738
3 D 2.240893
right2
keyRight value
0 B 1.867558
1 D -0.977278
2 E 0.950088
3 F -0.151357
left2.merge(right2, left_on='keyLeft', right_on='keyRight', how='inner')
keyLeft value_x keyRight value_y
0 B 0.400157 B 1.867558
1 D 2.240893 D -0.977278
When merging on keyLeft
from left
and keyRight
from right
, if you only want either of the keyLeft
or keyRight
(but not both) in the output, you can start by setting the index as a preliminary step.
left3 = left2.set_index('keyLeft')
left3.merge(right2, left_index=True, right_on='keyRight')
value_x keyRight value_y
0 0.400157 B 1.867558
1 2.240893 D -0.977278
Contrast this with the output of the command just before (that is, the output of left2.merge(right2, left_on='keyLeft', right_on='keyRight', how='inner')
), you'll notice keyLeft
is missing. You can figure out what column to keep based on which frame's index is set as the key. This may matter when, say, performing some OUTER JOIN operation.
DataFrames
For example, consider
right3 = right.assign(newcol=np.arange(len(right)))
right3
key value newcol
0 B 1.867558 0
1 D -0.977278 1
2 E 0.950088 2
3 F -0.151357 3
If you are required to merge only "new_val" (without any of the other columns), you can usually just subset columns before merging:
left.merge(right3[['key', 'newcol']], on='key')
key value newcol
0 B 0.400157 0
1 D 2.240893 1
If you're doing a LEFT OUTER JOIN, a more performant solution would involve map
:
# left['newcol'] = left['key'].map(right3.set_index('key')['newcol']))
left.assign(newcol=left['key'].map(right3.set_index('key')['newcol']))
key value newcol
0 A 1.764052 NaN
1 B 0.400157 0.0
2 C 0.978738 NaN
3 D 2.240893 1.0
As mentioned, this is similar to, but faster than
left.merge(right3[['key', 'newcol']], on='key', how='left')
key value newcol
0 A 1.764052 NaN
1 B 0.400157 0.0
2 C 0.978738 NaN
3 D 2.240893 1.0
To join on more than one column, specify a list for on
(or left_on
and right_on
, as appropriate).
left.merge(right, on=['key1', 'key2'] ...)
Or, in the event the names are different,
left.merge(right, left_on=['lkey1', 'lkey2'], right_on=['rkey1', 'rkey2'])

what about Result_*
there also are generated in the loop (because i don't think it's possible to add to the csv file)
i will go like this ; generate all the data at one rotate the matrix write in the file:
A = []
A.append(range(1, 5)) # an Example of you first loop
A.append(range(5, 9)) # an Example of you second loop
data_to_write = zip(*A)
# then you can write now row by row
You shouldn't use the control private tooltip, but the form one. This example works well:

myRTB.Location = new Point(10, 10);
myRTB.MouseEnter += new EventHandler(myRTB_MouseEnter);
myRTB.MouseLeave += new EventHandler(myRTB_MouseLeave);
}

First of all print
isn't a function in Python 2, it is a statement.
To suppress the automatic newline add a trailing ,
(comma). Now a space will be used instead of a newline.
Demo:
print 1,
print 2
output:
1 2
Or use Python 3's print()
function:
from __future__ import print_function
print(1, end=' ') # default value of `end` is '\n'
print(2)
As you can clearly see print()
function is much more powerful as we can specify any string to be used as end
rather a fixed space.
The problem you're running into is that you're trying to replace an entire row object. That is not allowed by the DataTable API. Instead you have to update the values in the columns of a row object. Or add a new row to the collection.
To update the column of a particular row you can access it by name or index. For instance you could write the following code to update the column "Foo" to be the value strVerse
dtResult.Rows(i)("Foo") = strVerse
You can also use Select-Object like so:
Get-ChildItem "C:\WINDOWS\System32" *.txt -Recurse | Select-Object FullName
Initially, it can be represented graphically as follow:
Then, the sort is applied myList.Sort();
Finally, when you did: myList' = myList2
, you lost the one of the reference but not the original and the collection stayed sorted.
If you use by reference (ref
) then myList'
and myList
will become the same (only one reference).
Note: I use myList'
to represent the parameter that you use in ChangeList
(because you gave the same name as the original)
As other people suggested, you need to use a combobox. However, most tutorials show you how to set up just one combobox and the process is quite tedious.
As I faced this problem before when entering a large amount of data from a list, I can suggest you use this autocomplete add-in . It helps you create the combobox on any cells you select and you can define a list to appear in the dropdown.
For the question
How can i run a jar file in command prompt but with arguments
.
To pass arguments to the jar file at the time of execution
java -jar myjar.jar arg1 arg2
In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:
String arg1 = args[0];
String arg2 = args[1];
There could be many reasons for Index not being used. Even after you specify hints, there are chances Oracle optimizer thinks otherwise and decide not to use Index. You need to go through the EXPLAIN PLAN part and see what is the cost of the statement with INDEX and without INDEX.
Assuming the Oracle uses CBO. Most often, if the optimizer thinks the cost is high with INDEX, even though you specify it in hints, the optimizer will ignore and continue for full table scan. Your first action should be checking DBA_INDEXES to know when the statistics are LAST_ANALYZED. If not analyzed, you can set table, index for analyze.
begin
DBMS_STATS.GATHER_INDEX_STATS ( OWNNAME=>user
, INDNAME=>IndexName);
end;
For table.
begin
DBMS_STATS.GATHER_TABLE_STATS ( OWNNAME=>user
, TABNAME=>TableName);
end;
In extreme cases, you can try setting up the statistics on your own.
You can use multiple ssh keys on Windows 10 and specify the type of access allowed.
Assuming you have created the ssh secure keys already and they were stored in C:\Users\[User]\.ssh
Open the folder C:\Users\[User]\.ssh
Create the file config
(no file extension)
Open the file in a text editor like Notepad, and add these configuration details for the first remote host and user. Keep both CMD and BASH paths or only pick one format. Then copy-and-paste below it for the other host/user combinations and amend as required. Save the file.
Host [git.domain.com]
User [user]
Port [number]
IdentitiesOnly=yes
PreferredAuthentications publickey
PasswordAuthentication no
# CMD
IdentityFile C:\Users\[User]\.ssh\[name_of_PRIVATE_key_file]
# BASH
IdentityFile /c/Users/[User]/.ssh/[name_of_PRIVATE_key_file]
Testing
$ ssh -T git@[git.domain.com]
Welcome to GitLab, @[User]!
C:\Users\[User]>ssh -T git@[git.domain.com]
Welcome to GitLab, @[User]!
ssh -Tv git@[git.domain.com]
(or -Tvv
or -Tvvv
for higher verbosity levels).I actually found a better way using the jQuery approach
var box = {
config:{
color: 'red'
},
init:function(config){
$.extend(this.config,config);
}
};
var myBox = box.init({
color: blue
});
Borrowed from python cookbook,
A more concise template code might look like this:
import csv
with open('stocks.csv') as f:
f_csv = csv.reader(f)
headers = next(f_csv)
for row in f_csv:
# Process row ...
I've created a dynamic way to call each event automatically. It perfect to focus a field, because it call the event just once, removing it after use.
function modalEvents() {
var modal = $('#modal');
var events = ['show', 'shown', 'hide', 'hidden'];
$(events).each(function (index, event) {
modal.on(event + '.bs.modal', function (e) {
var callback = modal.data(event + '-callback');
if (typeof callback != 'undefined') {
callback.call();
modal.removeData(event + '-callback');
}
});
});
}
You just need to call modalEvents()
on document ready.
Use:
$('#modal').data('show-callback', function() {
$("input#photo_name").focus();
});
So, you can use the same modal to load what you want without worry about remove events every time.
Here's an example in VB.NET
Public Function ShowtheDialog(caption As String, text As String, selStr As String) As String
Dim prompt As New Form()
prompt.Width = 280
prompt.Height = 160
prompt.Text = caption
Dim textLabel As New Label() With { _
.Left = 16, _
.Top = 20, _
.Width = 240, _
.Text = text _
}
Dim textBox As New TextBox() With { _
.Left = 16, _
.Top = 40, _
.Width = 240, _
.TabIndex = 0, _
.TabStop = True _
}
Dim selLabel As New Label() With { _
.Left = 16, _
.Top = 66, _
.Width = 88, _

}
Dim cmbx As New ComboBox() With { _
.Left = 112, _
.Top = 64, _
.Width = 144 _
}
cmbx.Items.Add("Dark Grey")
cmbx.Items.Add("Orange")
cmbx.Items.Add("None")
cmbx.SelectedIndex = 0
Dim confirmation As New Button() With { _
.Text = "In Ordnung!", _
.Left = 16, _
.Width = 80, _
.Top = 88, _
.TabIndex = 1, _
.TabStop = True _
}
AddHandler confirmation.Click, Sub(sender, e) prompt.Close()
prompt.Controls.Add(textLabel)
prompt.Controls.Add(textBox)
prompt.Controls.Add(selLabel)
prompt.Controls.Add(cmbx)
prompt.Controls.Add(confirmation)
prompt.AcceptButton = confirmation
prompt.StartPosition = FormStartPosition.CenterScreen
prompt.ShowDialog()
Return String.Format("{0};{1}", textBox.Text, cmbx.SelectedItem.ToString())

As you can see, it has more capabilities such as the ability to set background color temporarily, indefinitely, and other features. I also believe it is a bit more beginner friendly and easier to remember all of the functions.
#include <iostream>
#include "COLORS.h"
int main() {
std::cout << SetBackBLU << SetForeRED << endl;
std::cout << "I am red text on a blue background! :) " << endl;
return 0;
}
Simply include the header file in your project and you're ready to rock and roll with the colored terminal output.
You should \usepackage{longtable}
.
Both of these should work:
df.isnull().sum()
df.isna().sum()
DataFrame methods isna()
or isnull()
are completely identical.
Note: Empty strings ''
is considered as False (not considered NA)
The query either returned no rows or is erroneus, thus FALSE
is returned. Change it to
if (!$dbc || mysqli_num_rows($dbc) == 0)
mysqli_num_rows
:
Return Values
Returns TRUE on success or FALSE on failure. For SELECT, SHOW, DESCRIBE or EXPLAIN mysqli_query() will return a result object.
int i = 100;
char c = (char)i;
There is no way to append one char to another. But you can create an array of chars and use it.
You should upgrade the version of gradle. for example: com.android.build.gradle 1.3.0
this issue occurs when version of the gradle is changed.
We can also use it for the guideline of the constraint layout.
Create integer.xml file and add into
<item name="guideline_button_top" type="integer" format="float">0.60</item>
Use from a layout.xml file
app:layout_constraintGuide_percent="@integer/guideline_button_top"
We connect to servers that give us our external IP address and try to parse the IP from returning HTML pages. But when servers make small changes on these pages or remove them, these methods stop working properly.
Here is a method that takes the external IP address using a server which has been alive for years and returns a simple response rapidly... https://www.codeproject.com/Tips/452024/Getting-the-External-IP-Address

For those checking this around the year 2020:
Microsoft's System.Text.Json namespace is the new king in town. In terms of performance, it is the best as far as I can tell:
var model = new Model
{
Name = "Test Name",
Age = 5
};
string json = JsonSerializer.Serialize(model);
As some others have mentioned, NewtonSoft.Json is a very nice library as well.
Hi my friends This is how I solved this problem and I was happy to teach it to you as well I am in the Android application I encrypt a string containing text and emoj and send it to the server and save it in the mysql table and after receiving it from the server I decrypt it and display it in the textview. encoded and decoded my message before request and after response: I send Android app messages to mysql via pdo through this method and receive them with pdo. And I have no problem. I think it was a good way. Please like Thankful
public void main()
{
String message="hi mester ali moradi ?? how are you ?";
String encoded_message=encodeStringUrl(message);
String decode_message=decodeStringUrl(encoded_message);
}
public static String encodeStringUrl(String message) {
String encodedUrl =null;
try {
encodedUrl = URLEncoder.encode(message, "UTF-8");
} catch (UnsupportedEncodingException e) {
return encodedUrl;
}
return encodedUrl;
}
public static String decodeStringUrl(String message) {
String decodedUrl =null;
try {
decodedUrl = URLDecoder.decode(message, "UTF-8");
} catch (UnsupportedEncodingException e) {

The solution by user1236048 is correct, but the key point isn't called out. In your POJO classes used for the table's observable list, you not only have to set getter and setter methods, but a new one called Property. In Oracle's tableview tutorial (http://docs.oracle.com/javafx/2/ui_controls/table-view.htm), they left that key part off!
Here's what the Person class should look like:
public static class Person {
private final SimpleStringProperty firstName;
private final SimpleStringProperty lastName;
private final SimpleStringProperty email;
private Person(String fName, String lName, String email) {
this.firstName = new SimpleStringProperty(fName);
this.lastName = new SimpleStringProperty(lName);
this.email = new SimpleStringProperty(email);
}
public String getFirstName() {
return firstName.get();
}
public void setFirstName(String fName) {
firstName.set(fName);
}
public SimpleStringProperty firstNameProperty(){
return firstName;
}
public String getLastName() {
return lastName.get();
}
public void setLastName(String fName) {
lastName.set(fName);
}
public SimpleStringProperty lastNameProperty(){
return lastName;
}
public String getEmail() {
return email.get();
}
public void setEmail(String fName) {
email.set(fName);
}
public SimpleStringProperty emailProperty(){
return email;
}
}
If anyone is struggling with angular version 4+ (mine was 4.3.6). This was the sample code which worked for me.
First add the required imports
import { Http, Headers, Response, URLSearchParams } from '@angular/http';
Then for the api function. It's a login sample which can be changed as per your needs.
login(username: string, password: string) {
var headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded');
let urlSearchParams = new URLSearchParams();
urlSearchParams.append('email', username);
urlSearchParams.append('password', password);
let body = urlSearchParams.toString()
return this.http.post('http://localhost:3000/api/v1/login', body, {headers: headers})
.map((response: Response) => {
// login successful if user.status = success in the response
let user = response.json();
console.log(user.status)
if (user && "success" == user.status) {
// store user details and jwt token in local storage to keep user logged in between page refreshes
localStorage.setItem('currentUser', JSON.stringify(user.data));
}
});
}
When opening the h2-console, the JDBC URL must match the one specified in the properties:
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:testdb
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true
spring.h2.console.enabled=true
Which seems obvious, but I spent hours figuring this out..
u can make
'xxxx' text u search and will replace it with 'yyyy'
grep -Rn '**xxxx**' /path | awk -F: '{print $1}' | xargs sed -i 's/**xxxx**/**yyyy**/'
In my case, it just worked when I killed the Eclipse process, and restart the software.
Use the command svn status on your working copy to show the status of files, files that are not yet under version control (and not ignored) will have a question mark next to them.
As for ignoring files you need to edit the svn:ignore property, read the chapter Ignoring Unversioned Items in the svnbook at http://svnbook.red-bean.com/en/1.5/svn.advanced.props.special.ignore.html. The book also describes more about using svn status.
There is also an easy way for copying via the clipboard:
int keyIndex = words.TakeWhile(w => !w.IsKey).Count();
I often use following command to spin my PHP Laravel framework :
$ php artisan serve --port=8080
or
$ php -S localhost:8080 -t public/
In above command : - Artisan is command-line interface included with Laravel which use serve to call built in php server
To Run with built-in web server.
php -S <addr>:<port> -T
Here,
-S : Switch to Run with built-in web server.
-T : Switch to specify document root for built-in web server.
This is re-post for insert code also. This example included: - One object list - Each object hast child list. Ex:
var list1 = {
name: "Role A",
name_selected: false,
subs: [{
sub: "Read",
id: 1,
selected: false
}, {
sub: "Write",
id: 2,
selected: false
}, {
sub: "Update",
id: 3,
selected: false
}],
};
I'll 3 list like above and i'll add to a one object list
newArr.push(list1);
newArr.push(list2);
newArr.push(list3);
Then i'll do how to show checkbox with multiple group:
$scope.toggleAll = function(item) {
var toogleStatus = !item.name_selected;
console.log(toogleStatus);
angular.forEach(item, function() {
angular.forEach(item.subs, function(sub) {
sub.selected = toogleStatus;
});
});
};
$scope.optionToggled = function(item, subs) {
item.name_selected = subs.every(function(itm) {
return itm.selected;
})
$scope.txtRet = item.name_selected;
}
HTML:
<li ng-repeat="item in itemDisplayed" class="ng-scope has-pretty-child">
<div>
<ul>
<input type="checkbox" class="checkall" ng-model="item.name_selected" ng-click="toggleAll(item)"><span>{{item.name}}</span>
<div>
<li ng-repeat="sub in item.subs" class="ng-scope has-pretty-child">
<input type="checkbox" kv-pretty-check="" ng-model="sub.selected" ng-change="optionToggled(item,item.subs)"><span>{{sub.sub}}</span>
</li>
</div>
</ul>
</div>
<span>{{txtRet}}</span>
</li>
Fiddle: example
When you say
(a['x']==1) and (a['y']==10)
You are implicitly asking Python to convert (a['x']==1)
and (a['y']==10)
to boolean values.
NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a boolean value -- in other words, they raise
ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all().
when used as a boolean value. That's because its unclear when it should be True or False. Some users might assume they are True if they have non-zero length, like a Python list. Others might desire for it to be True only if all its elements are True. Others might want it to be True if any of its elements are True.
Because there are so many conflicting expectations, the designers of NumPy and Pandas refuse to guess, and instead raise a ValueError.
Instead, you must be explicit, by calling the empty()
, all()
or any()
method to indicate which behavior you desire.
In this case, however, it looks like you do not want boolean evaluation, you want element-wise logical-and. That is what the &
binary operator performs:
(a['x']==1) & (a['y']==10)
returns a boolean array.
By the way, as alexpmil notes,
the parentheses are mandatory since &
has a higher operator precedence than ==
.
Without the parentheses, a['x']==1 & a['y']==10
would be evaluated as a['x'] == (1 & a['y']) == 10
which would in turn be equivalent to the chained comparison (a['x'] == (1 & a['y'])) and ((1 & a['y']) == 10)
. That is an expression of the form Series and Series
.
The use of and
with two Series would again trigger the same ValueError
as above. That's why the parentheses are mandatory.
Thanks for the answers. Now I know that there are two ways of "SAVE AS" in Vim.
Assumed that I'm editing hello.txt.
a = [1,2,3,4,5]
b = [1,3,5,6]
c = list(set(a).intersection(set(b)))
Should work like a dream. And, if you can, use sets instead of lists to avoid all this type changing!
The arguments can never be null
. They just wont exist.
In other words, what you need to do is check the length of your arguments.
public static void main(String[] args)
{
// Check how many arguments were passed in
if(args.length == 0)
{
System.out.println("Proper Usage is: java program filename");
System.exit(0);
}
}
You can also add an anchor with follow attr:
(text-indent:-99999px;)
visibility: hidden;
position:absolute;
top:-80px;
and give the parent container a position relative.
Works perfect for me.
a = 0.000006;
b = 6;
c = a/b;
textbox.Text = c.ToString("0.000000");
As you requested:
textbox.Text = c.ToString("0.######");
This will only display out to the 6th decimal place if there are 6 decimals to display.

Python habitually returns None
from functions and methods that mutate the data, such as list.sort
, list.append
, and random.shuffle
, with the idea being that it hints to the fact that it was mutating.
If you want to take an iterable and return a new, sorted list of its items, use the sorted
builtin function.
Make sure the outermost div has the following CSS properties:
.outer {

overflow: hidden;

It's not related to Ken's case directly, but such an error also can occur if you copied .h file and forgot to change #ifndef
directive. In this case compiler will just skip definition of the class thinking that it's a duplication.
I am all for Eran Harel's solution and in cases where it isn't possible, Tomasz Nurkiewicz's suggestion for spying is excellent. However, it's worth noting that there are situations where neither would apply. E.g. if the login
method was a bit "beefier":
public class TestedClass {
public LoginContext login(String user, String password) {
LoginContext lc = new LoginContext("login", callbackHandler);
lc.doThis();
lc.doThat();
return lc;
}
}
... and this was old code that could not be refactored to extract the initialization of a new LoginContext
to its own method and apply one of the aforementioned solutions.
For completeness' sake, it's worth mentioning a third technique - using PowerMock to inject the mock object when the new
operator is called. PowerMock isn't a silver bullet, though. It works by applying byte-code manipulation on the classes it mocks, which could be dodgy practice if the tested classes employ byte code manipulation or reflection and at least from my personal experience, has been known to introduce a performance hit to the test. Then again, if there are no other options, the only option must be the good option:
@RunWith(PowerMockRunner.class)
@PrepareForTest(TestedClass.class)
public class TestedClassTest {
@Test
public void testLogin() {
LoginContext lcMock = mock(LoginContext.class);
whenNew(LoginContext.class).withArguments(anyString(), anyString()).thenReturn(lcMock);
TestedClass tc = new TestedClass();
tc.login ("something", "something else");
// test the login's logic
}
}
Example: Suppose you have set some text in textview and you want to provide a link on a particular text expression: "Click on #facebook will take you to facebook.com"
In layout xml:
<TextView
android:id="@+id/testtext"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
In Activity:
String text = "Click on #facebook will take you to facebook.com";
tv.setText(text);
Pattern tagMatcher = Pattern.compile("[#]+[A-Za-z0-9-_]+\\b");
String newActivityURL = "content://ankit.testactivity/";
Linkify.addLinks(tv, tagMatcher, newActivityURL);
Also create one tag provider as:
public class TagProvider extends ContentProvider {
@Override
public int delete(Uri arg0, String arg1, String[] arg2) {
// TODO Auto-generated method stub
return 0;
}
@Override
public String getType(Uri arg0) {
return "vnd.android.cursor.item/vnd.cc.tag";
}
@Override
public Uri insert(Uri arg0, ContentValues arg1) {

In manifest file make as entry for provider and test activity as:
<provider
android:name="ankit.TagProvider"
android:authorities="ankit.testactivity" />
<activity android:name=".TestActivity"
android:label = "@string/app_name">
<intent-filter >
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="vnd.android.cursor.item/vnd.cc.tag" />
</intent-filter>
</activity>
Now when you click on #facebook, it will invoke testactivtiy. And in test activity you can get the data as:
Uri uri = getIntent().getData();
For me, the following hack worked; Go to IIS -> Application Pools -> Advance Settings -> Process Model -> Identity Changed from Built-in Account (ApplicationPoolIdentity) to Custom Account (My Domain User)
In your view controller's header file add <UITextFieldDelegate>
to the definition of your controller's interface so that it conform to the UITextField delegate protocol...
@interface someViewController : UIViewController <UITextFieldDelegate>
... In the controller's implementation file (.m) add the following method, or the code inside it if you already have a viewDidLoad method ...
- (void)viewDidLoad
{
// Do any additional setup after loading the view, typically from a nib.
self.yourTextBox.delegate = self;
}
... Then, link yourTextBox to your actual text field
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField
{
if (theTextField == yourTextBox) {
[theTextField resignFirstResponder];
}
return YES;
}
If you only need the first row from each group we can do with drop_duplicates

re
(as in regular expressions) allows splitting on multiple characters at once:
$ string = "blah, lots , of , spaces, here "
$ re.split(', ',string)
['blah', 'lots ', ' of ', ' spaces', 'here ']
This doesn't work well for your example string, but works nicely for a comma-space separated list. For your example string, you can combine the re.split power to split on regex patterns to get a "split-on-this-or-that" effect.
$ re.split('[, ]',string)
['blah',
'',
'lots',
'',
'',
'',
'',
'of',
'',
'',
'',
'spaces',
'',
'here',
'']
Unfortunately, that's ugly, but a filter
will do the trick:
$ filter(None, re.split('[, ]',string))
['blah', 'lots', 'of', 'spaces', 'here']

I think your question isn't quite clear. There are several answers here on how to catch the data coming into a Linux's serial port, but perhaps your problem is the other way around?
If you need to catch the data coming out of a Linux's serial port and send it to a server, there are several little hardware gizmos that can do this, starting with the simple serial print server such as this Lantronix gizmo.
No, I'm not affiliated with Lantronix in any way.
If you are using Linux, these settings are available using /usr/bin/jcontrol
(or your path setting to get the current Java tools). You can also edit the files in ~/.java/deployment/deployment.properties
to set "deployment.security.level=MEDIUM".
Surprisingly, this information is not readily available from the Oracle web site. I miss java.sun.com...
It means the connection was successfully established at some point, but when you tried to commit right there, the connection was no longer open. The parameters you mentioned sound like connection pool settings. If so, they're unrelated to this problem. The most likely cause is a firewall between you and the database that is killing connections after a certain amount of idle time. The most common fix is to make your connection pool run a validation query when a connection is checked out from it. This will immediately identify and evict dead connnections, ensuring that you only get good connections out of the pool.
I show you here the easiest way using Vs2017 and Vs2019 Open your xsd with Visual Studio and generate a sample xml file as in the url suggested.
2. Within “XML Schema Explorer” scroll all the way down to find the root/data node. Right click on root/data node and it will show “Generate Sample XML”. If it does not show, it means you are not on the data element node but you are on any of the data definition node.
If you're using Apache just add:
<ifModule mod_headers.c>
Header set Access-Control-Allow-Origin: *
</ifModule>
in your configuration. This will cause all responses from your webserver to be accessible from any other site on the internet. If you intend to only allow services on your host to be used by a specific server you can replace the *
with the URL of the originating server:
Header set Access-Control-Allow-Origin: http://my.origin.host
I think you are looking for this function:
http://doc.qt.io/qt-5/qdatetime.html#toTime_t
uint QDateTime::toTime_t () const
Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).
On systems that do not support time zones, this function will behave as if local time were Qt::UTC.
See also setTime_t().
You can use Hyperlink instead of Button, like this:
<TextBlock>
<Hyperlink TextDecorations="{x:Null}">
<Image Width="16"
Height="16"
Margin="3"
Source="/YourProjectName;component/Images/close-small.png" />
</Hyperlink>
</TextBlock>
Try this way:
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]"));
String address = "[email protected],[email protected]";
InternetAddress[] iAdressArray = InternetAddress.parse(address);
message.setRecipients(Message.RecipientType.CC, iAdressArray);
Clustered basically means that the data is in that physical order in the table. This is why you can have only one per table.
Unclustered means it's "only" a logical order.
The only way to prevent offensive user input is to prevent all user input.
If you insist on allowing user input and need moderation, then incorporate human moderators.
You can define an operator that performs the output.
std::ostream& operator<<(std::ostream& lhs, WeekEnum e) {
switch(e) {
case Monday: lhs << "Monday"; break;
.. etc
}
return lhs;
}
To use Vim to retab a set of files (e.g. all the *.ts files in a directory hierarchy) from say 2 spaces to 4 spaces you can try this from the command line:
find . -name '*.ts' -print0 | xargs -0 -n1 vim -e '+set ts=2 noet | retab! | set ts=4 et | retab | wq'
What this is doing is using find
to pass all the matching files to xargs
(the -print0 option on find works with the -0 option to xargs in order to handle files w/ spaces in the name).
xargs runs vim in ex mode (-e
) on each file executing the given ex command which is actually several commands, to change the existing leading spaces to tabs, resetting the tab stop and changing the tabs back to spaces and finally saving and exiting.
Running in ex mode prevents this: Vim: Warning: Input is not from a terminal
for each file.
compare
has overloads for comparing substrings. If you're comparing whole strings you should just use ==
operator (and whether it calls compare
or not is pretty much irrelevant).
These are Unicode property shortcuts (\p{L}
for Unicode letters, \p{N}
for Unicode digits). They are supported by .NET, Perl, Java, PCRE, XML, XPath, JGSoft, Ruby (1.9 and higher) and PHP (since 5.1.0)
At any rate, that's a very strange regex. You should not be using alternation when a character class would suffice:
[\p{L}\p{N}_.-]*
The GNU site suggests this nice awk script, which prints both the words and their frequency.
Possible changes:
sort -nr
(and reverse word
and freq[word]
) to see the result in descending order.freq[3]++
- replace 3 with the column number.Here goes:
# wordfreq.awk --- print list of word frequencies
{
$0 = tolower($0) # remove case distinctions
# remove punctuation
gsub(/[^[:alnum:]_[:blank:]]/, "", $0)
for (i = 1; i <= NF; i++)
freq[$i]++
}
END {
for (word in freq)
printf "%s\t%d\n", word, freq[word]
}
You use dependency injection when you exactly know what type of objects you require at this point of time. While in case of factory pattern, you just delegate the process of creating objects to factory as you are unclear of what exact type of objects you require.

Borrowing directly from Gordon's very comprehensive answer, I note that your question mentions being page-specific in forcing HTTPS/SSL connections.
function forceHTTPS(){
$httpsURL = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
if( count( $_POST )>0 )
die( 'Page should be accessed with HTTPS, but a POST Submission has been sent here. Adjust the form to point to '.$httpsURL );
if( !isset( $_SERVER['HTTPS'] ) || $_SERVER['HTTPS']!=='on' ){
if( !headers_sent() ){
header( "Status: 301 Moved Permanently" );
header( "Location: $httpsURL" );
exit();
}else{
die( '<script type="javascript">document.location.href="'.$httpsURL.'";</script>' );
}
}
}
Then, as close to the top of these pages which you want to force to connect via PHP, you can require()
a centralised file containing this (and any other) custom functions, and then simply run the forceHTTPS()
function.
I have not implemented this kind of solution personally (I have tended to use the PHP solution, like the one above, for it's simplicity), but the following may be, at least, a good start.
RewriteEngine on
# Check for POST Submission
RewriteCond %{REQUEST_METHOD} !^POST$
# Forcing HTTPS
RewriteCond %{HTTPS} !=on [OR]
RewriteCond %{SERVER_PORT} 80
# Pages to Apply
RewriteCond %{REQUEST_URI} ^something_secure [OR]
RewriteCond %{REQUEST_URI} ^something_else_secure
RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
# Forcing HTTP
RewriteCond %{HTTPS} =on [OR]
RewriteCond %{SERVER_PORT} 443
# Pages to Apply
RewriteCond %{REQUEST_URI} ^something_public [OR]
RewriteCond %{REQUEST_URI} ^something_else_public
RewriteRule .* http://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
"copysign" is defined by IEEE 754, and part of the C99 specification. That's why it's in Python. The function cannot be implemented in full by abs(x) * sign(y) because of how it's supposed to handle NaN values.
>>> import math
>>> math.copysign(1, float("nan"))
1.0
>>> math.copysign(1, float("-nan"))
-1.0
>>> math.copysign(float("nan"), 1)
nan
>>> math.copysign(float("nan"), -1)
nan
>>> float("nan") * -1
nan
>>> float("nan") * 1
nan
>>>
That makes copysign() a more useful function than sign().
As to specific reasons why IEEE's signbit(x) is not available in standard Python, I don't know. I can make assumptions, but it would be guessing.
The math module itself uses copysign(1, x) as a way to check if x is negative or non-negative. For most cases dealing with mathematical functions that seems more useful than having a sign(x) which returns 1, 0, or -1 because there's one less case to consider. For example, the following is from Python's math module:
static double
m_atan2(double y, double x)
{
if (Py_IS_NAN(x) || Py_IS_NAN(y))
return Py_NAN;
if (Py_IS_INFINITY(y)) {
if (Py_IS_INFINITY(x)) {
if (copysign(1., x) == 1.)
/* atan2(+-inf, +inf) == +-pi/4 */
return copysign(0.25*Py_MATH_PI, y);
else
/* atan2(+-inf, -inf) == +-pi*3/4 */
return copysign(0.75*Py_MATH_PI, y);
}
/* atan2(+-inf, x) == +-pi/2 for finite x */
return copysign(0.5*Py_MATH_PI, y);
There you can clearly see that copysign() is a more effective function than a three-valued sign() function.
You wrote:
If I were a python designer, I would been the other way around: no cmp() builtin, but a sign()
That means you don't know that cmp() is used for things besides numbers. cmp("This", "That") cannot be implemented with a sign() function.
Edit to collate my additional answers elsewhere:
You base your justifications on how abs() and sign() are often seen together. As the C standard library does not contain a 'sign(x)' function of any sort, I don't know how you justify your views. There's an abs(int) and fabs(double) and fabsf(float) and fabsl(long) but no mention of sign. There is "copysign()" and "signbit()" but those only apply to IEEE 754 numbers.
With complex numbers, what would sign(-3+4j) return in Python, were it to be implemented? abs(-3+4j) return 5.0. That's a clear example of how abs() can be used in places where sign() makes no sense.
Suppose sign(x) were added to Python, as a complement to abs(x). If 'x' is an instance of a user-defined class which implements the __abs__(self) method then abs(x) will call x.__abs__(). In order to work correctly, to handle abs(x) in the same way then Python will have to gain a sign(x) slot.
This is excessive for a relatively unneeded function. Besides, why should sign(x) exist and nonnegative(x) and nonpositive(x) not exist? My snippet from Python's math module implementation shows how copybit(x, y) can be used to implement nonnegative(), which a simple sign(x) cannot do.
Python should support have better support for IEEE 754/C99 math function. That would add a signbit(x) function, which would do what you want in the case of floats. It would not work for integers or complex numbers, much less strings, and it wouldn't have the name you are looking for.
You ask "why", and the answer is "sign(x) isn't useful." You assert that it is useful. Yet your comments show that you do not know enough to be able to make that assertion, which means you would have to show convincing evidence of its need. Saying that NumPy implements it is not convincing enough. You would need to show cases of how existing code would be improved with a sign function.
And that it outside the scope of StackOverflow. Take it instead to one of the Python lists.
You might want to use Scanner to parse through and find the specific sections you want to modify. There's also Split and StringTokenizer that may work, but at the level you're working at Scanner might be what's needed.
Here's some additional info on what the difference is between them: Scanner vs. StringTokenizer vs. String.Split
Refining upon the answers found here I came up with the following:
getCurrentScript.js
var getCurrentScript = function () {
if (document.currentScript) {
return document.currentScript.src;
} else {
var scripts = document.getElementsByTagName('script');
return scripts[scripts.length-1].src;
}
};
module.exports = getCurrentScript;
getCurrentScriptPath.js
var getCurrentScript = require('./getCurrentScript');
var getCurrentScriptPath = function () {
var script = getCurrentScript();
var path = script.substring(0, script.lastIndexOf('/'));
return path;
};
module.exports = getCurrentScriptPath;
BTW: I'm using CommonJS module format and bundling with webpack.
Is numeric can be achieved via many ways, but i use my way

char[] digits = "0123456789".ToCharArray();
char[] letters = value.ToCharArray();
for (int k = 0; k < letters.Length; k++)
{
for (int i = 0; i < digits.Length; i++)
{
if (letters[k] != digits[i])
{
isNumeric = false;
break;
}
}
}
return isNumeric;
}

myCKEControl.EnterMode = CKEditor.NET.EnterMode.BR
Personally, I don't care if my resulting text only has <br>
and not <p>
. It renders perfectly fine and it looks the way I want it to. In the end, it works.
stay true to native (Boolean) property support and its powerful syntax like:
[elem].disabled = condition ? true : false; //done!
and for our own good collective coding experience, -please insist on others to support it as well.

There are multiple approaches you can use:

df1=df.withColumn("new_column","old_column")
df1=df.select("old_column".alias("new_column"))
you can put your json in a parameter and send it instead of put only your json in header:
$post_string= 'json_param=' . json_encode($data);
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $post_string);
curl_setopt($curl, CURLOPT_URL, 'http://webservice.local/'); // Set the url path we want to call
//execute post
$result = curl_exec($curl);
//see the results
$json=json_decode($result,true);
curl_close($curl);
print_r($json);
on the service side you can get your json string as a parameter:
$json_string = $_POST['json_param'];
$obj = json_decode($json_string);
then you can use your converted data as object.
And also, a colon can be used to label a statement. for example
var i = 100, j = 100;
outerloop:
while(i>0) {
while(j>0) {
j++
if(j>50) {
break outerloop;
}
}
i++
}

As other mentioned JSX
is not a standard Javascript extension. It's better to name your entry point of Application based on .js
and for the rest components, you can use .jsx
.
I have an important reason for why I'm using .JSX
for all component's file names.
Actually, In a large scale project with huge bunch of code, if we set all React's component with .jsx
extension, It'll be easier while navigating to different javascript files across the project(like helpers, middleware, etc.) and you know this is a React Component and not other types of the javascript file.
libmysql-ruby

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 ''
This is what helped me. My navigation bar is in the body tag. Entire code for navigation bar is in nav.html
file (without any html or body tag, only the code for navigation bar). In the target page, this goes in the head
tag:
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
Then in the body tag, a container is made with an unique id and a javascript block to load the nav.html
into the container, as follows:
<!--Navigation bar-->
<div id="nav-placeholder">
</div>
<script>
$(function(){
$("#nav-placeholder").load("nav.html");
});
</script>

So here is one sorting algorithm which can sort in any order , throughout array of any kind of objects , without the restriction of datatype comparison ( i.e. Number , String )
function smoothSort(items,prop,reverse) {
var length = items.length;
for (var i = (length - 1); i >= 0; i--) {
//Number of passes
for (var j = (length - i); j > 0; j--) {
//Compare the adjacent positions
if(reverse){
if (items[j][prop] > items[j - 1][prop]) {
//Swap the numbers
var tmp = items[j];
items[j] = items[j - 1];
items[j - 1] = tmp;
}
}
if(!reverse){
if (items[j][prop] < items[j - 1][prop]) {
//Swap the numbers
var tmp = items[j];
items[j] = items[j - 1];
items[j - 1] = tmp;
}
}
}
}
return items;
}
the first argument items is the array of objects ,
prop is the key of the object on which you want to sort ,
reverse is a boolean parameter which on being true results in Ascending order and in false it returns descending order.
<select id="ddlvalue" name="ddlvaluename">
<option value='0' disabled selected>Select Value</option>

<input type="submit" id="btn_submit" value="click me"/>
<script>
$('#btn_submit').on('click',function(){
$('#ddlvalue').val(0);

You could always write out the list of keys in addition to dumping the dict, and then reconstruct the OrderedDict

I think it's not possible. Though I found an app from google play called PHONE MUSIC which claims to : "Thus whenver someone puts you on hold just hit the hovering musical note and start playing music. Or play music while someones on the phone with you. "
Not taking anything away from Nikos' awesome answer, perhaps you can do this more simply:
<form name="telForm">
<input name="cb" type='checkbox' data-ng-modal='requireTel'>
<input name="tel" type="text" ng-model="..." ng-if='requireTel' ng-pattern="phoneNumberPattern" required/>
<button type="submit" ng-disabled="telForm.$invalid || telForm.$pristine">Submit</button>
</form>
Pay attention to the second input: We can use an ng-if
to control rendering and validation in forms.
If the requireTel
variable is unset, the second input would not only be hidden, but not rendered at all, thus the form will pass validation and the button will become enabled, and you'll get what you need.
Add servlet-api.jar into your classpath. It will be available into Tomcat's lib folder.
Please refer to the updated and optimized C# 7 version. I didn't want to remove the VB.NET version so I just posted it in a separate answer.
Seems it's not supported, I implemented by myself, FYI, hope it to be helpful:
I updated the VB version and from now on it raises an event before changing the collection so you can regret (useful when using with DataGrid
, ListView
and many more, that you can show an "Are you sure" confirmation to the user), the updated VB version is in the bottom of this message.
Please accept my apology that the screen is too narrow to contain my code, I don't like it either.

SwiftyBase64 (full disclosure: I wrote it) is a native Swift Base64 encoding (no decoding library. With it, you can encode standard Base64:
let bytesToEncode : [UInt8] = [1,2,3]
let base64EncodedString = SwiftyBase64.EncodeString(bytesToEncode)
or URL and Filename Safe Base64:
let bytesToEncode : [UInt8] = [1,2,3]
let base64EncodedString = SwiftyBase64.EncodeString(bytesToEncode, alphabet:.URLAndFilenameSafe)
This is compatible with the standards-based browsers, but will probably fail in IE. I'm providing it as a starting point. IE doesn't support DOM Range.

If you need to convert ALL columns to strings, you can simply use:
df = df.astype(str)
This is useful if you need everything except a few columns to be strings/objects, then go back and convert the other ones to whatever you need (integer in this case):
df[["D", "E"]] = df[["D", "E"]].astype(int)
In each class that you need to inherit from, you can run a loop of each class that needs init'd upon initiation of the child class...an example that can copied might be better understood...
class Female_Grandparent:
def __init__(self):
self.grandma_name = 'Grandma'
class Male_Grandparent:
def __init__(self):
self.grandpa_name = 'Grandpa'
class Parent(Female_Grandparent, Male_Grandparent):
def __init__(self):
Female_Grandparent.__init__(self)
Male_Grandparent.__init__(self)
self.parent_name = 'Parent Class'
class Child(Parent):
def __init__(self):
Parent.__init__(self)
#---------------------------------------------------------------------------------------#
for cls in Parent.__bases__: # This block grabs the classes of the child
cls.__init__(self) # class (which is named 'Parent' in this case),
# and iterates through them, initiating each one.
# The result is that each parent, of each child,
# is automatically handled upon initiation of the
# dependent class. WOOT WOOT! :D
#---------------------------------------------------------------------------------------#
g = Female_Grandparent()
print g.grandma_name
p = Parent()
print p.grandma_name
child = Child()
print child.grandma_name
if val is not None:
# ...
is the Pythonic idiom for testing that a variable is not set to None
. This idiom has particular uses in the case of declaring keyword functions with default parameters. is
tests identity in Python. Because there is one and only one instance of None
present in a running Python script/program, is
is the optimal test for this. As Johnsyweb points out, this is discussed in PEP 8 under "Programming Recommendations".
As for why this is preferred to
if not (val is None):
# ...
this is simply part of the Zen of Python: "Readability counts." Good Python is often close to good pseudocode.
Since posting the answer the latest versions of browsers prevent the command from working. I'll leave the answer visible but note it ONLY works on older browser versions.
Most browsers prevent you from closing windows with javascript that were not opened with window.open("https://example_url.com")
however, it is still possible to close the current window using the following command:
window.open('','_self').close()
This loads a blank url (the first argument) in the current window (the second argument) and then instantaneously closes the window. This works because when close()
is called, the current window has been opened by javascript.
Use Cygwin...
it has 32 and 64 bits versions
and it works fine from Windows 2000 (*)
to Windows 10 or Server 2019
I use Cygwin for a long time...
and recently tryed to substitute with Windows-Linux-Subsystems...
not for long...
I quickly went back to Cygwin again...
much more flexible, controlable and rich...
also less intrusive...
just add \bin to the path...
and you can use it anyware in Windows/Batch/Powershell...
or in a DOS-Box... or in a Powershell-Box...
Also you can install a ton of great packages
that really work... like nginX or PHP...
I even use the Cygwin PHP package in my IIS...
As a bonus wou can also use it from a bash shell...
(I think this was the original intent ;-))
This indicates the linux has delivered a SIGTERM
to your process. This is usually at the request of some other process (via kill()
) but could also be sent by your process to itself (using raise()
). This signal requests an orderly shutdown of your process.
If you need a quick cheatsheet of signal numbers, open a bash shell and:
$ kill -l
1) SIGHUP 2) SIGINT 3) SIGQUIT 4) SIGILL
5) SIGTRAP 6) SIGABRT 7) SIGBUS 8) SIGFPE
9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2
13) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT
17) SIGCHLD 18) SIGCONT 19) SIGSTOP 20) SIGTSTP
21) SIGTTIN 22) SIGTTOU 23) SIGURG 24) SIGXCPU
25) SIGXFSZ 26) SIGVTALRM 27) SIGPROF 28) SIGWINCH
29) SIGIO 30) SIGPWR 31) SIGSYS 34) SIGRTMIN
35) SIGRTMIN+1 36) SIGRTMIN+2 37) SIGRTMIN+3 38) SIGRTMIN+4
39) SIGRTMIN+5 40) SIGRTMIN+6 41) SIGRTMIN+7 42) SIGRTMIN+8
43) SIGRTMIN+9 44) SIGRTMIN+10 45) SIGRTMIN+11 46) SIGRTMIN+12
47) SIGRTMIN+13 48) SIGRTMIN+14 49) SIGRTMIN+15 50) SIGRTMAX-14
51) SIGRTMAX-13 52) SIGRTMAX-12 53) SIGRTMAX-11 54) SIGRTMAX-10
55) SIGRTMAX-9 56) SIGRTMAX-8 57) SIGRTMAX-7 58) SIGRTMAX-6
59) SIGRTMAX-5 60) SIGRTMAX-4 61) SIGRTMAX-3 62) SIGRTMAX-2
63) SIGRTMAX-1 64) SIGRTMAX
You can determine the sender by using an appropriate signal handler like:
#include <signal.h>
#include <stdio.h>
#include <stdlib.h>
void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
info->si_pid);
exit(0);
}
int main (void)
{
struct sigaction action = {
.sa_handler = NULL,
.sa_sigaction = sigterm_handler,
.sa_mask = 0,
.sa_flags = SA_SIGINFO,
.sa_restorer = NULL
};
sigaction(SIGTERM, &action, NULL);
sleep(60);
return 0;
}
Notice that the signal handler also includes a call to exit()
. It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).
Try:
var myUrl = "my.aspx?val=%2Fxyz2F";
var decodeUrl = System.Uri.UnescapeDataString(myUrl);
Personally, I ran these exact steps:
* Install Interop Assemblies: you can install from Microsoft's website https://www.microsoft.com/en-us/download/details.aspx?id=3508&tduid=(09cd06700e5e2553aa540650ec905f71)(256380)(2459594)(TnL5HPStwNw-yuTjfb1FeDiXvvZxhh.R.Q)()
* Check assemblies version: check the version of the assemblies on development and production machines. The assemblies will be in the GAC, in widows 7 this folder is %windir%\assembly.
* Create a Desktop folder: the service uses the desktop folder under systemprofile so you will need to create this folder if not there, here is the location of the folder:
For 64 bit applications : C:\Windows\SysWOW64\config\systemprofile\Desktop
For 32 bit applications : C:\Windows\System32\config\systemprofile\Desktop
* Add DCOM user permissions:
---start the run window and type 'dcomcnfg'.
---Expand Component Services –> Computers –> My Computer –> DCOM Config.
---Look for Microsoft Excel Application. Right click on it and select properties, then select the Security tab.
---Select the Customize radio button under 'Launch and Activation Permissions' and 'Access Permission' and click the Edit button for both to add users as follows.
---------Click the Add button and users 'IIS_IUSRS' and 'NETWORK SERVICE' and give them full privileges.
---Go to the Identity tab and select "The interactive user" option.
---Click Apply and OK.

The best way to get filetype-specific indentation is to use filetype plugin indent on
in your vimrc. Then you can specify things like set sw=4 sts=4 et
in .vim/ftplugin/c.vim, for example, without having to make those global for all files being edited and other non-C type syntaxes will get indented correctly, too (even lisps).
It works for me.

If you are working on Windows then do the following:
From this directory:
C:\Users\ [your username] \AppData\Roaming , delete NPM folder then install Angular using this command npm install -g @angular/cli
You have to escape the backslash, so try this:
str = "Hello\\nWorld";
Here are more escaped characters in Javascript.
You can write a jQuery function like this to determine if an element is in the viewport.
Include this somewhere after jQuery is included:
$.fn.isInViewport = function() {
var elementTop = $(this).offset().top;
var elementBottom = elementTop + $(this).outerHeight();
var viewportTop = $(window).scrollTop();
var viewportBottom = viewportTop + $(window).height();
return elementBottom > viewportTop && elementTop < viewportBottom;
};
Sample usage:
$(window).on('resize scroll', function() {
if ($('#Something').isInViewport()) {
// do something
} else {
// do something else
}
});
Note that this only checks the top and bottom positions of elements, it doesn't check if an element is outside of the viewport horizontally.
I think you can initialize the variables a value like -1
,
because if the int
type variables is not initialized it can't be used.
When you want to check if it is not the value you want you can check if it is -1
.
Lets Code with Swift for the random number or random string :)
let quotes: NSArray = ["R", "A", "N", "D", "O", "M"]
let randomNumber = arc4random_uniform(UInt32(quotes.count))
let quoteString = quotes[Int(randomNumber)]
print(quoteString)
it will give you output randomly.
Here is my solution to see if I am using an argparse variable
import argparse
ap = argparse.ArgumentParser()
ap.add_argument("-1", "--first", required=True)
ap.add_argument("-2", "--second", required=True)
ap.add_argument("-3", "--third", required=False)
# Combine all arguments into a list called args
args = vars(ap.parse_args())
if args["third"] is not None:
# do something
This might give more insight to the above answer which I used and adapted to work for my program.
I cleaned my main App Project AND the Android Library Project which it uses. Solved the issue
Another useful thing to do with numpy.histogram
is to plot the output as the x and y coordinates on a linegraph. For example:
arr = np.random.randint(1, 51, 500)
y, x = np.histogram(arr, bins=np.arange(51))
fig, ax = plt.subplots()
ax.plot(x[:-1], y)
fig.show()
This can be a useful way to visualize histograms where you would like a higher level of granularity without bars everywhere. Very useful in image histograms for identifying extreme pixel values.
