Yes, but if you need to insert the resulting string somewhere without it being converted back, you need to do:
str.replace(/'/g,"'"); // and so on
Building on icova's answer, here's the code so you can use a custom HTML5 validation message:
$(function() {
var requiredCheckboxes = $(':checkbox[required]');
requiredCheckboxes.change(function() {
if (requiredCheckboxes.is(':checked')) {requiredCheckboxes.removeAttr('required');}
else {requiredCheckboxes.attr('required', 'required');}
});
$("input").each(function() {
$(this).on('invalid', function(e) {
e.target.setCustomValidity('');
if (!e.target.validity.valid) {
e.target.setCustomValidity('Please, select at least one of these options');
}
}).on('input, click', function(e) {e.target.setCustomValidity('');});
});
});
You can achieve the solution, by doing this:
JavaScript:
var myValue = document.getElementById("@(ViewBag.CC)").value;
or if you want to use jQuery
, then:
jQuery
var myValue = $('#' + '@(ViewBag.CC)').val();
There is some faster way (https://www.youtube.com/watch?v=TSjEMLBAYVc):
This should do what you want:
sed 's/two.*/BLAH/'
$ echo " one two three five
> four two five five six
> six one two seven four" | sed 's/two.*/BLAH/'
one BLAH
four BLAH
six one BLAH
The $
is unnecessary because the .*
will finish at the end of the line anyways, and the g
at the end is unnecessary because your first match will be the first two
to the end of the line.
I'm late to the party, but this solution worked for me quite well. Based on this library, you can use a function lik this - setting the image, quality, max-width, and output format (jepg,png):
function compress(source_img_obj, quality, maxWidth, output_format){
var mime_type = "image/jpeg";
if(typeof output_format !== "undefined" && output_format=="png"){
mime_type = "image/png";
}
maxWidth = maxWidth || 1000;
var natW = source_img_obj.naturalWidth;
var natH = source_img_obj.naturalHeight;
var ratio = natH / natW;
if (natW > maxWidth) {
natW = maxWidth;
natH = ratio * maxWidth;
}
var cvs = document.createElement('canvas');
cvs.width = natW;
cvs.height = natH;
var ctx = cvs.getContext("2d").drawImage(source_img_obj, 0, 0, natW, natH);
var newImageData = cvs.toDataURL(mime_type, quality/100);
var result_image_obj = new Image();
result_image_obj.src = newImageData;
return result_image_obj;
}
Does '%' mean either "mod" or "rem" in C?
In C, %
is the remainder1.
..., the result of the
/
operator is the algebraic quotient with any fractional part discarded ... (This is often called "truncation toward zero".) C11dr §6.5.5 6The operands of the
%
operator shall have integer type. C11dr §6.5.5 2The result of the
/
operator is the quotient from the division of the first operand by the second; the result of the%
operator is the remainder ... C11dr §6.5.5 5
What's the difference between “mod” and “remainder”?
C does not define "mod", such as the integer modulus function used in Euclidean division or other modulo. "Euclidean mod" differs from C's a%b
operation when a
is negative.
// a % b
7 % 3 --> 1
7 % -3 --> 1
-7 % 3 --> -1
-7 % -3 --> -1
Modulo as Euclidean division
7 modulo 3 --> 1
7 modulo -3 --> 1
-7 modulo 3 --> 2
-7 modulo -3 --> 2
Candidate modulo code:
int modulo_Euclidean(int a, int b) {
int m = a % b;
if (m < 0) {
// m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
m = (b < 0) ? m - b : m + b;
}
return m;
}
Note about floating point: double fmod(double x, double y)
, even though called "fmod", it is not the same as Euclidean division "mod", but similar to C integer remainder:
The
fmod
functions compute the floating-point remainder ofx/y
. C11dr §7.12.10.1 2
fmod( 7, 3) --> 1.0
fmod( 7, -3) --> 1.0
fmod(-7, 3) --> -1.0
fmod(-7, -3) --> -1.0
Disambiguation: C also has a similar named function double modf(double value, double *iptr)
which breaks the argument value into integral and fractional parts, each of which has the same type and sign as the argument. This has little to do with the "mod" discussion here except name similarity.
[Edit Dec 2020]
For those who want proper functionality in all cases, an improved modulo_Euclidean()
that 1) detects mod(x,0)
and 2) a good and no UB result with modulo_Euclidean2(INT_MIN, -1)
. Inspired by 4 different implementations of modulo with fully defined behavior.
int modulo_Euclidean2(int a, int b) {
if (b == 0) TBD_Code(); // perhaps return -1 to indicate failure?
if (b == -1) return 0; // This test needed to prevent UB of `INT_MIN % -1`.
int m = a % b;
if (m < 0) {
// m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
m = (b < 0) ? m - b : m + b;
}
return m;
}
1 Prior to C99, C's definition of %
was still the remainder from division, yet then /
allowed negative quotients to round down rather than "truncation toward zero". See Why do you get different values for integer division in C89?. Thus with some pre-C99 compilation, %
code can act just like the Euclidean division "mod". The above modulo_Euclidean()
will work with this alternate old-school remainder too.
If you don't want to output a Python script every time you save, or you don't want to restart the IPython kernel:
On the command line, you can use nbconvert
:
$ jupyter nbconvert --to script [YOUR_NOTEBOOK].ipynb
As a bit of a hack, you can even call the above command in an IPython notebook by pre-pending !
(used for any command line argument). Inside a notebook:
!jupyter nbconvert --to script config_template.ipynb
Before --to script
was added, the option was --to python
or --to=python
, but it was renamed in the move toward a language-agnostic notebook system.
You should try JRebel, which does the hot deploy stuff pretty well. A bit expensive, but worth the money. They have a trial version.
I use FOR XML PATH solution to replace multiple spaces into single space
The idea is to replace spaces with XML tags Then split XML string into string fragments without XML tags Finally concatenating those string values by adding single space characters between two
Here is how final UDF function can be called
select dbo.ReplaceMultipleSpaces(' Sample text with multiple space ')
You don't have to use the message passing to obtain or modify DOM. I used chrome.tabs.executeScript
instead. In my example I am using only activeTab permission, therefore the script is executed only on the active tab.
part of manifest.json
"browser_action": {
"default_title": "Test",
"default_popup": "index.html"
},
"permissions": [
"activeTab",
"<all_urls>"
]
index.html
<!DOCTYPE html>
<html>
<head></head>
<body>
<button id="test">TEST!</button>
<script src="test.js"></script>
</body>
</html>
test.js
document.getElementById("test").addEventListener('click', () => {
console.log("Popup DOM fully loaded and parsed");
function modifyDOM() {
//You can play with your DOM here or check URL against your regex
console.log('Tab script:');
console.log(document.body);
return document.body.innerHTML;
}
//We have permission to access the activeTab, so we can call chrome.tabs.executeScript:
chrome.tabs.executeScript({
code: '(' + modifyDOM + ')();' //argument here is a string but function.toString() returns function's code
}, (results) => {
//Here we have just the innerHTML and not DOM structure
console.log('Popup script:')
console.log(results[0]);
});
});
This worked for me. When I import my csv file I added na_values = ' '. Spaces are not included in the default NaN values.
df= pd.read_csv(filepath,na_values = ' ')
There's actually a simpler way than having a view for each redirect - you can do it directly in urls.py
:
from django.http import HttpResponsePermanentRedirect
urlpatterns = patterns(
'',
# ...normal patterns here...
(r'^bad-old-link\.php',
lambda request: HttpResponsePermanentRedirect('/nice-link')),
)
A target can be a callable as well as a string, which is what I'm using here.
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
You can find Resetting the Root Password in the MySQL documentation.
ref will probably choke on null since it presumably expects to be modifying an existing object. out expects null, since it's returning a new object.
Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:
type: "GET",
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
withCredentials: true
},
success: function (data) {
alert(data);
});
use NumpyEncoder it will process json dump successfully.without throwing - NumPy array is not JSON serializable
import numpy as np
import json
from numpyencoder import NumpyEncoder
arr = array([ 0, 239, 479, 717, 952, 1192, 1432, 1667], dtype=int64)
json.dumps(arr,cls=NumpyEncoder)
For cases where your images happen to be the same size (which is a common case for displaying image processing results), you can use numpy's concatenate to simplify your code.
To stack vertically (img1 over img2):
vis = np.concatenate((img1, img2), axis=0)
To stack horizontally (img1 to the left of img2):
vis = np.concatenate((img1, img2), axis=1)
To verify:
import cv2
import numpy as np
img1 = cv2.imread('img1.png')
img2 = cv2.imread('img2.png')
vis = np.concatenate((img1, img2), axis=1)
cv2.imwrite('out.png', vis)
The out.png image will contain img1 on the left and img2 on the right.
I was using Android Pie and nothing seemed to worked so I played around with app:tabTextAppearance attribute. I know its not the perfect answer but might help someone.
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabTextAppearance="@style/TextAppearance.AppCompat.Caption" />
Another way simpler than me has worked with SQL Developer 4 in Windows 7
spool "path_to_file\\filename.txt"
query to execute
spool of
You have to execute it as a script, because if not only the query will be saved in the output file In the path name I use the double character "\" as a separator when working with Windows and SQL, The output file will display the query and the result.
If the problem domain has some kind of string header concept, this could be modelled as an enum.
switch(GetStringHeader(s))
{
case StringHeader.ABC: ...
case StringHeader.QWERTY: ...
...
}
StringHeader GetStringHeader(string s)
{
if (s.StartsWith("ABC")) return StringHeader.ABC;
...
}
enum StringHeader { ABC, QWERTY, ... }
Because 'abstract' means the method is meant to be overridden and one can't override 'static' methods.
String[] paramIdIdList={"P001","P002","P003"};
StringBuilder builder = new StringBuilder();
for(String paramId : paramIdIdList) {
builder.append(paramId+",");
}
builder.deleteCharAt(builder.length() -1);
String paramIds = builder.toString();
System.Out.Println(paramIds );
Does this work? Untested but should get the point across.
UPDATE FUNCTIONS
SET Func_TaxRef =
(
SELECT Min(TAX.Tax_Code) AS MinOfTax_Code
FROM TAX, FUNCTIONS F1
WHERE F1.Func_Pure <= [Tax_ToPrice]
AND F1.Func_Year=[Tax_Year]
AND F1.Func_ID = FUNCTIONS.Func_ID
GROUP BY F1.Func_ID;
)
Basically for each row in FUNCTIONS, the subquery determines the minimum current tax code and sets FUNCTIONS.Func_TaxRef to that value. This is assuming that FUNCTIONS.Func_ID is a Primary or Unique key.
This one works for me.
Here's my PHP:

alert();
$.ajax({
type: "POST",
url: "create.php",
data: {vendorName: $("#vendorName_new").val(), owner: $("#owner_new").val(), city: $("#city_new").val()},
success: function(){
$(this).hide();
$('div.success').fadeIn();
showUsers()

});
});
Have you tried the Generate Scripts

Don't forget to convert your object into Json first using Gson()
val fromUserJson = Gson().toJson(notificationRequest.fromUser)
Then you can easily convert it back into an object using this awesome library
val fromUser = Gson().fromJson(fromUserJson, User::class.java)

hope this helps.
I guess the issue here is that you are updating INV_DISCOUNT and the INV_TOTAL uses the INV_DISCOUNT. so that is the issue here. You can use returning clause of update statement to use the new INV_DISCOUNT and use it to update INV_TOTAL.
this is a generic example let me know if this explains the point i mentioned
CREATE OR REPLACE PROCEDURE SingleRowUpdateReturn
IS
empName VARCHAR2(50);
empSalary NUMBER(7,2);
BEGIN
UPDATE emp
SET sal = sal + 1000
WHERE empno = 7499
RETURNING ename, sal
INTO empName, empSalary;
DBMS_OUTPUT.put_line('Name of Employee: ' || empName);
DBMS_OUTPUT.put_line('New Salary: ' || empSalary);
END;
More general sorted, where the key
keyword defines the sorting method, minus before numerical type indicates descending:
>>> x = Counter({'a':5, 'b':3, 'c':7})
>>> sorted(x.items(), key=lambda k: -k[1]) # Ascending
[('c', 7), ('a', 5), ('b', 3)]
Very similar to Vishnu's answer but uses the lapply to map all the data to characters then to assign them as the headers. This is really helpful if your data is imported as factors.
DF[] <- lapply(DF, as.character)
colnames(DF) <- DF[1, ]
DF <- DF[-1 ,]
note that that if you have a lot of numeric data or factors you want you'll need to convert them back. In this case it may make sense to store the character data frame, extract the row you want, and then apply it to the original data frame
tempDF <- DF
tempDF[] <- lapply(DF, as.character)
colnames(DF) <- tempDF[1, ]
DF <- DF[-1 ,]
tempDF <- NULL
To stop Jenkins Please avoid shutting down the Java process or the Windows service. These are not usual commands. Use those only if your Jenkins is causing problems.
Use Jenkins' way to stop that protects from data loss.

where [command] can be any one of the following
Example: if my local PC is running Jenkins at port 8080, it will be
http://localhost:8080/exit
You can try the regex here to filter out the columns starting with "foo"
df.filter(regex='^foo*')
If you need to have the string foo in your column then
df.filter(regex='foo*')
would be appropriate.
For the next step, you can use
df[df.filter(regex='^foo*').values==1]
to filter out the rows where one of the values of 'foo*' column is 1.
For my case I'm facing it on iOS, and I've tried to reset and clear all cache using below command but failed too, despite many comments saying that the root cause is there is react packager running somewhere accidentally, I've restarted my mac and the problem still remained.
watchman watch-del-all && rm -rf node_modules/ && yarn cache clean && yarn install && yarn start --reset-cache
The solution is, to delete the build folder @ /ios/build
, then execute react-native run-ios

Have you tried the GNU make documentation? It has a whole section about conditionals with examples.
You can write an object that behaves like a dict
quite easily with ABCs (Abstract Base Classes) from the collections.abc
module. It even tells you if you missed a method, so below is the minimal version that shuts the ABC up.
from collections.abc import MutableMapping
class TransformedDict(MutableMapping):
"""A dictionary that applies an arbitrary key-altering
function before accessing the keys"""
def __init__(self, *args, **kwargs):
self.store = dict()
self.update(dict(*args, **kwargs)) # use the free update to set keys
def __getitem__(self, key):
return self.store[self._keytransform(key)]
def __setitem__(self, key, value):
self.store[self._keytransform(key)] = value
def __delitem__(self, key):
del self.store[self._keytransform(key)]
def __iter__(self):
return iter(self.store)
def __len__(self):
return len(self.store)
def _keytransform(self, key):
return key
You get a few free methods from the ABC:
class MyTransformedDict(TransformedDict):
def _keytransform(self, key):
return key.lower()
s = MyTransformedDict([('Test', 'test')])
assert s.get('TEST') is s['test'] # free get
assert 'TeSt' in s # free __contains__
# free setdefault, __eq__, and so on
import pickle
# works too since we just use a normal dict
assert pickle.loads(pickle.dumps(s)) == s
I wouldn't subclass dict
(or other builtins) directly. It often makes no sense, because what you actually want to do is implement the interface of a dict
. And that is exactly what ABCs are for.
I have modified the UILabel by following code:

I spotted half of the problem: I can't use the 'indexer' notation to objects (my_object[0]). Is there a way to bypass it?
No; an object literal, as the name implies, is an object, and not an array, so you cannot simply retrieve a property based on an index, since there is no specific order of their properties. The only way to retrieve their values is by using the specific name:
var someVar = options.filters.firstName; //Returns 'abc'
Or by iterating over them using the for ... in
loop:
for(var p in options.filters) {
var someVar = options.filters[p]; //Returns the property being iterated
}
Yes, you can do it. you can either use css or javascript to hide the reCaptcha v3 badge.
display: none
or visibility: hidden
to hide the reCaptcha batch. It's easy and quick..grecaptcha-badge {
display:none !important;
}
var el = document.querySelector('.grecaptcha-badge');
el.style.display = 'none';
Hiding the badge is valid, according to the google policy and answered in faq here. It is recommended to show up the privacy policy and terms of use from google as shown below.
I agree with Brad's answer, that you can fix this problem by editing your target/project by hand, deleting any lines like this:
PROVISIONING_PROFILE = "487F3EAC-05FB-4A2A-9EA0-31F1F35760EB";
"PROVISIONING_PROFILE[sdk=iphoneos*]" = "487F3EAC-05FB-4A2A-9EA0-31F1F35760EB";
However, in Xcode 4.2 and later, there is a much easier way to access this text and select and delete it. In the Project Navigator on the left, select your project (the topmost line of the Project Navigator). Now simply choose View > Version Editor > Show Version Editor. This displays your project as text, and you can search for PROVISIONING and delete the troublesome line, right there in the editor pane of Xcode.
Try this:
[DataType(DataType.PhoneNumber, ErrorMessage = "Provided phone number not valid")]

Just wondering why you are using 2 directives?
It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.
Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).
It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.
Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.
"Cannot invoke an expression whose type lacks a call signature."
In your code :
class Post extends Component {
public toggleBody: string;
constructor() {
this.toggleBody = this.setProp('showFullBody');
}
public showMore(): boolean {
return this.toggleBody(true);
}
public showLess(): boolean {
return this.toggleBody(false);
}
}
You have public toggleBody: string;
. You cannot call a string
as a function. Hence errors on : this.toggleBody(true);
and this.toggleBody(false);
I'm assuming you've got a nice fat USB HD and a good connection to the net. You can use apt-mirror to essentially create your own debian mirror.
Typescript recognizes the Date interface out of the box - just like you would with a number, string, or custom type. So Just use:
myDate : Date;
Since my previous answer I came up with another solution that is different and perhaps better. This code allows processes to be run more than 60 times a minute with microsecond precision. You need the usleep program to make this work. Should be good to up to 50 times a second.

I had a similar problem:
module cv2 has no attribute "cv2.TrackerCSRT_create"
My Python version is 3.8.0 under Windows 10. The problem was the opencv version installation.
So I fixed this way (cmd prompt with administrator privileges):
pip uninstall opencv-python
pip install opencv-contrib-python
Anyway you can read the following guide:
I've added the <%%
literal tag delimiter as an answer to this because of its obscurity. This will tell erb not to interpret the <%
part of the tag which is necessary for js apps like displaying chart.js tooltips etc.
Update (Fixed broken link)
Everything about ERB can now be found here: https://puppet.com/docs/puppet/5.3/lang_template_erb.html#tags
This works perfect for me
private string GeneratePasswordResetToken()
{
string token = Guid.NewGuid().ToString();
var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(token);
return Convert.ToBase64String(plainTextBytes);
}
I know its bit old post. Still, it might help some one.
Instead of tag,if possible you can this as well.
<script type="text/javascript">
function IsItWorking() {
// Do your stuff here ...
alert("YES, It Works...!!!");
}
</script>
`<asp:HyperLinkID="Link1"NavigateUrl="javascript:IsItWorking();"` `runat="server">IsItWorking?</asp:HyperLink>`
Any comments on this?
Already everyone has provided enough good answer for your problem. Now from the all suggestions, you need to decided which will fit your requirement. There are two types of collection which you need to know. One is unmodified collection and other one collection which will allow you to modify the object later.
So, Here I will give short example for two use cases.
Immutable collection creation :: When you don't want to modify the collection object after creation
List<Element> elementList = Arrays.asList(array)
Mutable collection creation :: When you may want to modify the created collection object after creation.
List<Element> elementList = new ArrayList<Element>(Arrays.asList(array));
That error is caused by your Eclipse configuration. You can reduce it to a warning. Better still, use a Base64 encoder that isn't part of a non-public API. Apache Commons has one, or when you're already on Java 1.8, then use java.util.Base64
.
private void makeTitleCenter(String title, Toolbar toolbar) {
if (title != null && !TextUtils.isEmpty(title.trim())) {
final String tag = " ";
if (getSupportActionBar() != null) {
getSupportActionBar().setTitle(tag);
}
TextView titleTv = null;
View leftBtn = null;
for (int i = 0; i < toolbar.getChildCount(); i++) {
View view = toolbar.getChildAt(i);
CharSequence text = null;
if (view instanceof TextView && (text = ((TextView) view).getText()) != null && text.equals(tag)) {
titleTv = (TextView) view;
} else if (view instanceof ImageButton) {
leftBtn = view;
}
}
if (titleTv != null) {
final TextView fTitleTv = titleTv;
final View fLeftBtn = leftBtn;
fTitleTv.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
fTitleTv.getViewTreeObserver().removeOnGlobalLayoutListener(this);
int leftWidgetWidth = fLeftBtn != null ? fLeftBtn.getWidth() : 0;
fTitleTv.setPadding(DimenUtil.getResources().getDisplayMetrics().widthPixels / 2 - leftWidgetWidth - fTitleTv.getWidth() / 2, 0, 0, 0);
fTitleTv.requestLayout();
}
});
}
}
}
The following code snippet enables/disables a button depending on whether at least one checkbox on the page has been checked.
$('input[type=checkbox]').change(function () {
$('#test > tbody tr').each(function () {
if ($('input[type=checkbox]').is(':checked')) {
$('#btnexcellSelect').removeAttr('disabled');
} else {
$('#btnexcellSelect').attr('disabled', 'disabled');
}
if ($(this).is(':checked')){
console.log( $(this).attr('id'));
}else{
console.log($(this).attr('id'));
}
});
});

Is the Config/setup.php
file actually in /test/content/home/
or is in your document root? it is best to make all references relative to your document root.
include $_SERVER['DOCUMENT_ROOT'] . "Config/setup.php";
Your current code assumes that the location of setup.php
is in /text/content/home/Config/setup.php
, is this correct?
I think this can be done without any complex mathematical equations and theories. Below is a proposal for an in place and O(2n) time complexity solution:
Input form assumptions :
# of numbers in bag = n
# of missing numbers = k
The numbers in the bag are represented by an array of length n
Length of input array for the algo = n
Missing entries in the array (numbers taken out of the bag) are replaced by the value of the first element in the array.
Eg. Initially bag looks like [2,9,3,7,8,6,4,5,1,10]. If 4 is taken out, value of 4 will become 2 (the first element of the array). Therefore after taking 4 out the bag will look like [2,9,3,7,8,6,2,5,1,10]
The key to this solution is to tag the INDEX of a visited number by negating the value at that INDEX as the array is traversed.
IEnumerable<int> GetMissingNumbers(int[] arrayOfNumbers)
{
List<int> missingNumbers = new List<int>();
int arrayLength = arrayOfNumbers.Length;
//First Pass
for (int i = 0; i < arrayLength; i++)
{
int index = Math.Abs(arrayOfNumbers[i]) - 1;
if (index > -1)
{
arrayOfNumbers[index] = Math.Abs(arrayOfNumbers[index]) * -1; //Marking the visited indexes
}
}
//Second Pass to get missing numbers
for (int i = 0; i < arrayLength; i++)
{
//If this index is unvisited, means this is a missing number
if (arrayOfNumbers[i] > 0)
{
missingNumbers.Add(i + 1);
}
}
return missingNumbers;
}
Usually, xampp
port error occurs because the default port 80
xampp
trying to access is in use by another application. Most of the times this application is Skype.
So, you have 2 methods to solve this problem:
These methods are well explained in this post How to debug xampp port 80 error
Just add below lines to your /etc/phpmyadmin/config.inc.php
file in the bottom:
$i++;
$cfg['Servers'][$i]['host'] = 'HostName:port'; //provide hostname and port if other than default
$cfg['Servers'][$i]['user'] = 'userName'; //user name for your remote server
$cfg['Servers'][$i]['password'] = 'Password'; //password
$cfg['Servers'][$i]['auth_type'] = 'config'; // keep it as config
You will get Current Server:
drop down with both 127.0.0.1
and one what you have provided with $cfg['Servers'][$i]['host']
can switch between the servers.

You could write a script to update the FK's for you.. check out this blog: http://multunus.com/2011/03/how-to-easily-merge-two-identical-mysql-databases/
They have a clever script to use the information_schema tables to get the "id" columns:
SET @db:='id_new';
select @max_id:=max(AUTO_INCREMENT) from information_schema.tables;
select concat('update ',table_name,' set ', column_name,' = ',column_name,'+',@max_id,' ; ') from information_schema.columns where table_schema=@db and column_name like '%id' into outfile 'update_ids.sql';
use id_new
source update_ids.sql;
As @jAndy mentioned, there is no properly javascript code to detect a window being closed. I started from what @Syno had proposed.
I had pass though a situation like that and provided you follow these steps, you'll be able to detect it.
I tested it on Chrome 67+ and Firefox 61+.
var wrapper = function () { //ignore this
var closing_window = false;
$(window).on('focus', function () {
closing_window = false;
//if the user interacts with the window, then the window is not being
//closed
});
$(window).on('blur', function () {
closing_window = true;
if (!document.hidden) { //when the window is being minimized
closing_window = false;
}
$(window).on('resize', function (e) { //when the window is being maximized
closing_window = false;
});
$(window).off('resize'); //avoid multiple listening
});
$('html').on('mouseleave', function () {
closing_window = true;
//if the user is leaving html, we have more reasons to believe that he's
//leaving or thinking about closing the window
});
$('html').on('mouseenter', function () {
closing_window = false;
//if the user's mouse its on the page, it means you don't need to logout
//them, didn't it?
});
$(document).on('keydown', function (e) {
if (e.keyCode == 91 || e.keyCode == 18) {
closing_window = false; //shortcuts for ALT+TAB and Window key
}
if (e.keyCode == 116 || (e.ctrlKey && e.keyCode == 82)) {
closing_window = false; //shortcuts for F5 and CTRL+F5 and CTRL+R
}
});
// Prevent logout when clicking in a hiperlink
$(document).on("click", "a", function () {
closing_window = false;
});
// Prevent logout when clicking in a button (if these buttons rediret to some page)
$(document).on("click", "button", function () {
closing_window = false;
});
// Prevent logout when submiting
$(document).on("submit", "form", function () {
closing_window = false;
});
// Prevent logout when submiting
$(document).on("click", "input[type=submit]", function () {
closing_window = false;
});
var toDoWhenClosing = function() {
//write a code here likes a user logout, example:
//$.ajax({
// url: '/MyController/MyLogOutAction',
// async: false,
// data: {
// },
// error: function () {

// success: function (data) {
// },
//});
};
window.onbeforeunload = function () {
if (closing_window) {
toDoWhenClosing();
}
};
};
While iterating the list, if you want to remove the element is possible. Let see below my examples,
ArrayList<String> names = new ArrayList<String>();
names.add("abc");
names.add("def");
names.add("ghi");
names.add("xyz");
I have the above names of Array list. And i want to remove the "def" name from the above list,
for(String name : names){
if(name.equals("def")){
names.remove("def");
}
}
The above code throws the ConcurrentModificationException exception because you are modifying the list while iterating.
So, to remove the "def" name from Arraylist by doing this way,
Iterator<String> itr = names.iterator();
while(itr.hasNext()){
String name = itr.next();
if(name.equals("def")){
itr.remove();
}
}
The above code, through iterator we can remove the "def" name from the Arraylist and try to print the array, you would be see the below output.
Output : [abc, ghi, xyz]
The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods
index.php
<html>
<body>
<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>
</body>
</html>
site2.php
<html>
<body>
Hello <?php echo $_POST["name"]; ?>!<br>
Your mail is <?php echo $_POST["mail"]; ?>.
</body>
</html>
output
Hello "name" !
Your email is "[email protected]" .
create table scores (
user_id int,
score int
)
select t.range as [score range], count(*) as [number of occurences]
from (
select user_id,
case when score >= 0 and score < 10 then '0-9'
case when score >= 10 and score < 20 then '10-19'
...
else '90-99' as range
from scores) t
group by t.range
Do this instead:
values = [[1,2,3],[4,5]]
for x in values:
if len(x) == 3:
print(x)
<input id='r1' type='radio' class='rg' name="asdf"/>
<input id='r2' type='radio' class='rg' name="asdf"/>
<input id='r3' type='radio' class='rg' name="asdf"/>
<input id='r4' type='radio' class='rg' name="asdf"/><br/>
<input type='text' id='r1edit'/>
jquery part
$(".rg").change(function () {
if ($("#r1").attr("checked")) {
$('#r1edit:input').removeAttr('disabled');
}
else {
$('#r1edit:input').attr('disabled', 'disabled');
}
});
here is the DEMO
You may use pip
for that without using the network. See in the docs (search for "Install a particular source archive file"). Any of those should work:
pip install relative_path_to_seaborn.tar.gz
pip install absolute_path_to_seaborn.tar.gz
pip install file:///absolute_path_to_seaborn.tar.gz
Or you may uncompress the archive and use setup.py
directly with either pip
or python
:
cd directory_containing_tar.gz
tar -xvzf seaborn-0.10.1.tar.gz
pip install seaborn-0.10.1
python setup.py install
Of course, you should also download required packages and install them the same way before you proceed.
Here is a simple solution, which uses a deep object comparison to check for duplicates (without resorting to converting to JSON, which is inefficient and hacky)
var newArr = _.filter(oldArr, function (element, index) {
// tests if the element has a duplicate in the rest of the array
for(index += 1; index < oldArr.length; index += 1) {
if (_.isEqual(element, oldArr[index])) {
return false;
}
}
return true;
});
It filters out all elements if they have a duplicate later in the array - such that the last duplicate element is kept.
The testing for a duplicate uses _.isEqual
which performs an optimised deep comparison between the two objects see the underscore isEqual documentation for more info.
edit: updated to use _.filter
which is a cleaner approach
I know there are a lot of other answers, but this article is nice and concise and forces you to check all of your HttpPosts, not just some of them:
http://richiban.wordpress.com/2013/02/06/validating-net-mvc-4-anti-forgery-tokens-in-ajax-requests/
It uses HTTP headers instead of trying to modify the form collection.
//make sure to add this to your global action filters
[AttributeUsage(AttributeTargets.Class)]
public class ValidateAntiForgeryTokenOnAllPosts : AuthorizeAttribute
{
public override void OnAuthorization( AuthorizationContext filterContext )
{
var request = filterContext.HttpContext.Request;
// Only validate POSTs
if (request.HttpMethod == WebRequestMethods.Http.Post)
{
// Ajax POSTs and normal form posts have to be treated differently when it comes
// to validating the AntiForgeryToken
if (request.IsAjaxRequest())
{
var antiForgeryCookie = request.Cookies[AntiForgeryConfig.CookieName];
var cookieValue = antiForgeryCookie != null
? antiForgeryCookie.Value
: null;
AntiForgery.Validate(cookieValue, request.Headers["__RequestVerificationToken"]);
}
else
{
new ValidateAntiForgeryTokenAttribute()
.OnAuthorization(filterContext);
}
}
}
}
var token = $('[name=__RequestVerificationToken]').val();
var headers = {};
headers["__RequestVerificationToken"] = token;
$.ajax({
type: 'POST',
url: '/Home/Ajax',
cache: false,
headers: headers,
contentType: 'application/json; charset=utf-8',
data: { title: "This is my title", contents: "These are my contents" },
success: function () {
...
},
error: function () {
...
}
});
This is because your Image name contains "-" symbol . the only allowed characters are [a-zA-Z0-9_.]

I found this approach the simplest and lightest.
Here is the working example: http://codepen.io/c3zar22/pen/QNoYXN
Below are the explanations:
this would be the markup:
<label for="attach-project-file">
<span id="remove-project-file" class="close">x</span>
<div class="filename" id="attached-project-file">Click to select a file</div>
</label>
<input id="attach-project-file" type="file">
hide the input in a hacky way like this:
#attach-project-file {
width: 0.1px;
height: 0.1px;
opacity: 0;
overflow: hidden;
position: absolute;
z-index: -1;
}
style the corresponding label instead
[for="attach-project-file"] {
/* your styles here */
}
style "remove file" button
.close {
font-size: 16px;
padding: 10px;
position: absolute;
top: 0;
right: 0;
cursor: pointer;
font-style: normal;
}
.filename
element will be used to display the selected file
below is the commented JS code needed (using jQuery) to make it work:
var $attach = $('#attach-project-file'),
$remove = $('#remove-project-file'),
$name = $('#attached-project-file');
// initially hide the remove button
$remove.hide();
// do this when file input has changed
// i.e.: a file has been selected
$attach.on('change', function() {
var val = $(this).val();
if (val !== '') {
// if value different than empty
// show the file name as text
// hide/text/fadeIn creates a nice effect when changing the text
$name
.hide()
.text(val)
.fadeIn();
// show the remove button
$remove.fadeIn();
} else {
// if value empty, means the file has been removed
// show the default text
$name
.hide()
.text('Click to select a file')
.fadeIn();
// hide remove button
$remove.fadeOut();
}
});
// remove selected file when clicking the remove button
// prevent click bubbling to the parent label and triggering file selection
$remove.on('click', function(e) {
e.preventDefault();
e.stopPropagation();
$attach
.val('')
.change(); // trigger change event
});
I was stucked with this problem for a long time (CORS does not work in FF, but works in Chrome and others). No advice could help. Finally, i found that my local dev subdomain (like sub.example.dev) was not explicitly mentioned in /etc/hosts, thus FF just is not able to find it and shows confusing error message 'Aborted...' in dev tools panel.
Putting the exact subdomain into my local /etc/hosts fixed the problem. /etc/hosts is just a plain-text file in unix systems, so you can open it under the root user and put your subdomain in front of '127.0.0.1' ip address.
contents_re = re.match(r'[^\(]*\((?P<contents>[^\(]+)\)', data)
if contents_re:
print(contents_re.groupdict()['contents'])
If anyone else runs into this issue and none of the above solutions work due to "Duplicate identifier" issues, run this:
npm install typings --global
With older versions of typings things mess up and you'll get a bunch of "Duplicate identifier" issues. Also you don't need to use --ambient
anymore as far as I could tell.
So once typings is up to date, this should work (using the Angular 2 quickstart).
Run:
npm install lodash --save
typings install lodash --save
First, add this to systemjs.config.js:
'lodash': 'node_modules/lodash/lodash.js'
Now you can use this in any file: import * as _ from 'lodash';
Delete your typings folder and run npm install
if you're still having issues.
This is not possible directly, because chronologically, WHERE happens before SELECT, which always is the last step in the execution chain.
You can do a sub-select and filter on it:
SELECT * FROM
(
SELECT A.identifier
, A.name
, TO_NUMBER(DECODE( A.month_no
, 1, 200803
, 2, 200804
, 3, 200805
, 4, 200806
, 5, 200807
, 6, 200808
, 7, 200809
, 8, 200810
, 9, 200811
, 10, 200812
, 11, 200701
, 12, 200702
, NULL)) as MONTH_NO
, TO_NUMBER(TO_CHAR(B.last_update_date, 'YYYYMM')) as UPD_DATE
FROM table_a A
, table_b B
WHERE A.identifier = B.identifier
) AS inner_table
WHERE
MONTH_NO > UPD_DATE
Interesting bit of info moved up from the comments:
There should be no performance hit. Oracle does not need to materialize inner queries before applying outer conditions -- Oracle will consider transforming this query internally and push the predicate down into the inner query and will do so if it is cost effective. – Justin Cave

Center with Paint.getTextBounds():
private Rect r = new Rect();
private void drawCenter(Canvas canvas, Paint paint, String text) {
canvas.getClipBounds(r);
int cHeight = r.height();
int cWidth = r.width();
paint.setTextAlign(Paint.Align.LEFT);
paint.getTextBounds(text, 0, text.length(), r);
float x = cWidth / 2f - r.width() / 2f - r.left;
float y = cHeight / 2f + r.height() / 2f - r.bottom;
canvas.drawText(text, x, y, paint);
}
Paint.Align.CENTER doesn't mean that the reference point of the text is vertically centered. The reference point is always on the baseline. So, why not use Paint.Align.LEFT? You have to calculate the reference point anyway.
Paint.descent() has the disadvantage, that it doesn't consider the real text. Paint.descent() retrieves the same value, regardless of whether the text contains letters with descents or not. That's why I use r.bottom instead.
I have had some problems with Canvas.getHeight() if API < 16. That's why I use Canvas.getClipBounds(Rect) instead. (Do not use Canvas.getClipBounds().getHeight() as it allocates memory for a Rect.)
For reasons of performance, you should allocate objects before they are used in onDraw(). As drawCenter() will be called within onDraw() the object Rect r is preallocated as a field here.
I tried to put the code of the two top answers into my own code (August 2015) and made a screenshot to compare the results:
The text should be centered within the red filled rectangle. My code produces the white text, the other two codes produces altogether the gray text (they are actually the same, overlapping). The gray text is a little bit too low and two much on the right.

sumr
is implemented in terms of foldRight
:
final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append)
foldRight
is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.
EDIT: it was fixed in EF version 6.1.1. and this answer is no more actual
For SQL Server and EF4-6, Count() performs about two times faster than Any().
When you run Table.Any(), it will generate something like(alert: don't hurt the brain trying to understand it)
SELECT
CASE WHEN ( EXISTS (SELECT
1 AS [C1]
FROM [Table] AS [Extent1]
)) THEN cast(1 as bit) WHEN ( NOT EXISTS (SELECT
1 AS [C1]
FROM [Table] AS [Extent2]
)) THEN cast(0 as bit) END AS [C1]
FROM ( SELECT 1 AS X ) AS [SingleRowTable1]
that requires 2 scans of rows with your condition.
I don't like to write Count() > 0
because it hides my intention. I prefer to use custom predicate for this:
public static class QueryExtensions
{
public static bool Exists<TSource>(this IQueryable<TSource> source, Expression<Func<TSource, bool>> predicate)
{
return source.Count(predicate) > 0;
}
}
Generally using stored procedures is better for perfomances. For example in previous versions of SQL Server if you put the function in JOIN condition the cardinality estimate is 1 (before SQL 2012) and 100 (after SQL 2012 and before of SQL 2017) and the engine can generate a bad execution plan.
Also if you put it in WHERE clause the SQL Engine can generate a bad execution plan.
With SQL 2017 Microsoft introduced the feature called interleaved execution in order to produce a more accurate estimate but the stored procedure remains the best solution.
For more details look the following article of Joe Sack https://techcommunity.microsoft.com/t5/sql-server/introducing-interleaved-execution-for-multi-statement-table/ba-p/385417
Another and easy way using cat command
cat filename | awk '{print $2,$3,$4,$5,$6,$1}' > newfilename
It seems to me that your Hibernate libraries are not found (NoClassDefFoundError: org/hibernate/boot/archive/scan/spi/ScanEnvironment
as you can see above).
Try checking to see if Hibernate core is put in as dependency:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.0.11.Final</version>
<scope>compile</scope>
</dependency>
n = Math.floor(x);
remainder = x % 1;
I am using v2.1.0
and none of the above answers worked for me.
This did though:
import express from "express";
import http from "http";
const app = express();
const server = http.createServer(app);
const sio = require("socket.io")(server, {
handlePreflightRequest: (req, res) => {
const headers = {
"Access-Control-Allow-Headers": "Content-Type, Authorization",
"Access-Control-Allow-Origin": req.headers.origin, //or the specific origin you want to give access to,
"Access-Control-Allow-Credentials": true
};
res.writeHead(200, headers);
res.end();
}
});
sio.on("connection", () => {
console.log("Connected!");
});
server.listen(3000);
Why this is not possible:
Because String and Integer are not in the same Object hierarchy.
Object
/ \
/ \
String Integer
The casting which you are trying, works only if they are in the same hierarchy, e.g.
Object
/
/
A
/
/
B
In this case, (A) objB
or (Object) objB
or (Object) objA
will work.
Hence as others have mentioned already, to convert an integer to string use:
String.valueOf(integer)
, or Integer.toString(integer)
for primitive,
or
Integer.toString()
for the object.
I would like to add another solution to this that does not require a dummy constructor. Since dummy constructors are a bit messy and subsequently confusing. We can provide a safe constructor and by annotating the constructor arguments we allow jackson to determine the mapping between constructor parameter and field.
so the following will also work. Note the string inside the annotation must match the field name.
import com.fasterxml.jackson.annotation.JsonProperty;
public class ApplesDO {
private String apple;
public String getApple() {
return apple;
}
public void setApple(String apple) {
this.apple = apple;
}
public ApplesDO(CustomType custom){
//constructor Code
}
public ApplesDO(@JsonProperty("apple")String apple) {
}
}
Select the Object -> Format -> Selection Pane -> Double click to change the name
If you are going to follow the examples given (using getter/setter or setting it in the constructor) change it to private since those are ways to control what is set in the variable.
It doesn't make sense to keep the property public with all those things added to the class.
Use @Named
to differentiate between different objects of the same type bound in the same scope.
@Named("maxWaitTime")
public long maxWaitTimeMs;
@Named("minWaitTime")
public long minWaitTimeMs;
Without the @Named
qualifier, the injector would not know which long to bind to which variable.
If you want to create annotations that act like @Named
, use the @Qualifier
annotation when creating them.
If you look at @Named
, it is itself annotated with @Qualifier
.
Unlikely.
Evaluate it in a try..catch
or whatever your language provides.
I think there is a lot of confusion about which weights are used for what. I am not sure I know precisely what bothers you so I am going to cover different topics, bear with me ;).
The weights from the class_weight
parameter are used to train the classifier.
They are not used in the calculation of any of the metrics you are using: with different class weights, the numbers will be different simply because the classifier is different.
Basically in every scikit-learn classifier, the class weights are used to tell your model how important a class is. That means that during the training, the classifier will make extra efforts to classify properly the classes with high weights.
How they do that is algorithm-specific. If you want details about how it works for SVC and the doc does not make sense to you, feel free to mention it.
Once you have a classifier, you want to know how well it is performing.
Here you can use the metrics you mentioned: accuracy
, recall_score
, f1_score
...
Usually when the class distribution is unbalanced, accuracy is considered a poor choice as it gives high scores to models which just predict the most frequent class.
I will not detail all these metrics but note that, with the exception of accuracy
, they are naturally applied at the class level: as you can see in this print
of a classification report they are defined for each class. They rely on concepts such as true positives
or false negative
that require defining which class is the positive one.
precision recall f1-score support
0 0.65 1.00 0.79 17
1 0.57 0.75 0.65 16
2 0.33 0.06 0.10 17
avg / total 0.52 0.60 0.51 50
F1 score:/usr/local/lib/python2.7/site-packages/sklearn/metrics/classification.py:676: DeprecationWarning: The
default `weighted` averaging is deprecated, and from version 0.18,
use of precision, recall or F-score with multiclass or multilabel data
or pos_label=None will result in an exception. Please set an explicit
value for `average`, one of (None, 'micro', 'macro', 'weighted',
'samples'). In cross validation use, for instance,
scoring="f1_weighted" instead of scoring="f1".
You get this warning because you are using the f1-score, recall and precision without defining how they should be computed! The question could be rephrased: from the above classification report, how do you output one global number for the f1-score? You could:
avg / total
result above. It's also called macro averaging.'weighted'
in scikit-learn will weigh the f1-score by the support of the class: the more elements a class has, the more important the f1-score for this class in the computation.These are 3 of the options in scikit-learn, the warning is there to say you have to pick one. So you have to specify an average
argument for the score method.
Which one you choose is up to how you want to measure the performance of the classifier: for instance macro-averaging does not take class imbalance into account and the f1-score of class 1 will be just as important as the f1-score of class 5. If you use weighted averaging however you'll get more importance for the class 5.
The whole argument specification in these metrics is not super-clear in scikit-learn right now, it will get better in version 0.18 according to the docs. They are removing some non-obvious standard behavior and they are issuing warnings so that developers notice it.
Last thing I want to mention (feel free to skip it if you're aware of it) is that scores are only meaningful if they are computed on data that the classifier has never seen. This is extremely important as any score you get on data that was used in fitting the classifier is completely irrelevant.
Here's a way to do it using StratifiedShuffleSplit
, which gives you a random splits of your data (after shuffling) that preserve the label distribution.
from sklearn.datasets import make_classification
from sklearn.cross_validation import StratifiedShuffleSplit
from sklearn.metrics import accuracy_score, f1_score, precision_score, recall_score, classification_report, confusion_matrix
# We use a utility to generate artificial classification data.
X, y = make_classification(n_samples=100, n_informative=10, n_classes=3)
sss = StratifiedShuffleSplit(y, n_iter=1, test_size=0.5, random_state=0)
for train_idx, test_idx in sss:
X_train, X_test, y_train, y_test = X[train_idx], X[test_idx], y[train_idx], y[test_idx]
svc.fit(X_train, y_train)
y_pred = svc.predict(X_test)
print(f1_score(y_test, y_pred, average="macro"))
print(precision_score(y_test, y_pred, average="macro"))
print(recall_score(y_test, y_pred, average="macro"))
Hope this helps.
On a higher level:
1) Async keyword enables the await and that's all it does. Async keyword does not run the method in a separate thread. The beginning f async method runs synchronously until it hits await on a time-consuming task.
2) You can await on a method that returns Task or Task of type T. You cannot await on async void method.
3) The moment main thread encounters await on time-consuming task or when the actual work is started, the main thread returns to the caller of the current method.
4) If the main thread sees await on a task that is still executing, it doesn't wait for it and returns to the caller of the current method. In this way, the application remains responsive.
5) Await on processing task, will now execute on a separate thread from the thread pool.
6) When this await task is completed, all the code below it will be executed by the separate thread
Below is the sample code. Execute it and check the thread id
using System;
using System.Threading;
using System.Threading.Tasks;

I think what you need might be simply:
\d( \w)?
Note that your regex would have worked too if it was written as \d \w|\d
instead of \d|\d \w
.
This is because in your case, once the regex matches the first option, \d
, it ceases to search for a new match, so to speak.
Here is some code that I recently wrote. I think that it provides a basic explanation of combining class/ID names with pseudoclasses.

The max length of a string on my machine is 1,073,741,791.
You see, Strings aren't limited by integer as is commonly believed.
Memory restrictions aside, Strings cannot have more than 230 (1,073,741,824) characters, since a 2GB limit is imposed by the Microsoft CLR (Common Language Runtime). 33 more than my computer allowed.
Now, here's something you're welcome to try yourself.
Create a new C# console app in Visual Studio and then copy/paste the main method here:
static void Main(string[] args)
{
Console.WriteLine("String test, by Nicholas John Joseph Taylor");
Console.WriteLine("\nTheoretically, C# should support a string of int.MaxValue, but we run out of memory before then.");
Console.WriteLine("\nThis is a quickish test to narrow down results to find the max supported length of a string.");
Console.WriteLine("\nThe test starts ...now:\n");
int Length = 0;
string s = "";
int Increment = 1000000000; // We know that s string with the length of 1000000000 causes an out of memory exception.
LoopPoint:
// Make a string appendage the length of the value of Increment
StringBuilder StringAppendage = new StringBuilder();
for (int CharacterPosition = 0; CharacterPosition < Increment; CharacterPosition++)
{
StringAppendage.Append("0");
}
// Repeatedly append string appendage until an out of memory exception is thrown.
try
{
if (Increment > 0)
while (Length < int.MaxValue)
{
Length += Increment;
s += StringAppendage.ToString(); // Append string appendage the length of the value of Increment
Console.WriteLine("s.Length = " + s.Length + " at " + DateTime.Now.ToString("dd/MM/yyyy HH:mm"));
}
}
catch (OutOfMemoryException ex) // Note: Any other exception will crash the program.
{
Console.WriteLine("\n" + ex.Message + " at " + DateTime.Now.ToString("dd/MM/yyyy HH:mm") + ".");
Length -= Increment;
Increment /= 10;
Console.WriteLine("After decimation, the value of Increment is " + Increment + ".");
}
catch (Exception ex2)
{
Console.WriteLine("\n" + ex2.Message + " at " + DateTime.Now.ToString("dd/MM/yyyy HH:mm") + ".");
Console.WriteLine("Press a key to continue...");
Console.ReadKey();
}
if (Increment > 0)
{
goto LoopPoint;
}
Console.WriteLine("Test complete.");
Console.WriteLine("\nThe max length of a string is " + s.Length + ".");
Console.WriteLine("\nPress any key to continue.");
Console.ReadKey();
}
My results were as follows:

SQlite does not have a specific datetime type. You can use TEXT
, REAL
or INTEGER
types, whichever suits your needs.
SQLite does not have a storage class set aside for storing dates and/or times. Instead, the built-in Date And Time Functions of SQLite are capable of storing dates and times as TEXT, REAL, or INTEGER values:
- TEXT as ISO8601 strings ("YYYY-MM-DD HH:MM:SS.SSS").
- REAL as Julian day numbers, the number of days since noon in Greenwich on November 24, 4714 B.C. according to the proleptic Gregorian calendar.
- INTEGER as Unix Time, the number of seconds since 1970-01-01 00:00:00 UTC.
Applications can chose to store dates and times in any of these formats and freely convert between formats using the built-in date and time functions.
SQLite built-in Date and Time functions can be found here.

Another possibility for this warning (and, most likely, problems with app behavior) is that the original author of the app relied on session.auto_start

If you don't want to mess with the code and just need it to work, you can always change php configuration and restart php-fpm (if this is a web app):
/etc/php.d/my-new-file.ini :
session.auto_start = 1

I'm not entirely sure that I've understood the question because this is a fairly straightforward answer, but here goes... :)
Have you tried setting the overflow property of the container to visible or auto?
#some_div {
height:100%;
background:black;
overflow: visible;
}
Adding that should push the black container to whatever size your dynamic container requires. I prefer visible to auto because auto seems to come with scroll bars...
Came here looking for an answer to the same problem, but I'm using WCF for NET Core. If you're in the same boat, use:
client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication =
new X509ServiceCertificateAuthentication()
{
CertificateValidationMode = X509CertificateValidationMode.None,
RevocationMode = X509RevocationMode.NoCheck
};
If you just want the extension, you can use pathinfo
:
$ext = pathinfo($file_path, PATHINFO_EXTENSION);
Since there are many different kinds of casting each with different semantics, static_cast<> allows you to say "I'm doing a legal conversion from one type to another" like from int to double. A plain C-style cast can mean a lot of things. Are you up/down casting? Are you reinterpreting a pointer?
Presently Package name starting with "com.example" is not allowed to upload in the app -store. Otherwise , all other package names starting with "com" are allowed .

Provided that your server is receiving a string that looks something like this (which it should if you're using jQuery serialize()
):
"param1=someVal¶m2=someOtherVal"
...something like this is probably all you need:
$params = array();
parse_str($_GET, $params);
$params
should then be an array modeled how you would expect. Note this works also with HTML arrays.
See the following for more information: http://www.php.net/manual/en/function.parse-str.php
Yor $.post
has no data. You need to pass the form data. You can use serialize()
to post the form data. Try this
$("#post-btn").click(function(){
$.post("process.php", $('#reg-form').serialize() ,function(data){
alert(data);
});
});

You can use any of the below code to get the controller name
@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString();
If you are using MVC 3 you can use
@ViewContext.Controller.ValueProvider.GetValue("controller").RawValue
In my case (I'm using typescript) I was trying to simulate response with fake data where the data is assigned later on. My first attempt was with:
let response = {status: 200, data: []};
and later, on the assignment of the fake data it starts complaining that it is not assignable to type 'never[]'. Then I defined the response like follows and it accepted it..
let dataArr: MyClass[] = [];
let response = {status: 200, data: dataArr};
and assigning of the fake data:
response.data = fakeData;
Can't you just change working directory within the python script using os.chdir(target)
? I agree, I can't see any way of doing it from the jar command itself.
If you don't want to permanently change directory, then store the current directory (using os.getcwd()
)in a variable and change back afterwards.
You can tee
the iterator using, itertools.tee
, and check for StopIteration
on the teed iterator.
The answers here, as usual, expect a level of interactivity.
The problem is when something is listening through HTTP.sys; then, the PID is always 4 and, as most people find, you need some tool to find the real owner.
Here's how to identify the offending process programmatically. No TcpView, etc (as good as those tools are). Does rely on netsh; but then, the problem is usually related to HTTP.sys.
$Uri = "http://127.0.0.1:8989" # for example
# Shows processes that have registered URLs with HTTP.sys
$QueueText = netsh http show servicestate view=requestq verbose=yes | Out-String
# Break into text chunks; discard the header
$Queues = $QueueText -split '(?<=\n)(?=Request queue name)' | Select-Object -Skip 1
# Find the chunk for the request queue listening on your URI
$Queue = @($Queues) -match [regex]::Escape($Uri -replace '/$')
if ($Queue.Count -eq 1)
{
# Will be null if could not pick out exactly one PID
$ProcessId = [string]$Queue -replace '(?s).*Process IDs:\s+' -replace '(?s)\s.*' -as [int]
if ($ProcessId)
{
Write-Verbose "Identified process $ProcessId as the HTTP listener. Killing..."
Stop-Process -Id $ProcessId -Confirm
}
}

If you are working with TFS connected then right click on file which you need to compare (through source control explorer) and it presents you a window like this -
Now change path of source file in 'Souce Path:' and you get comparision through VS comparision tool.
Similarly you can compare folder also which compares all files of a folder at once.
TreeViewItem tempItem = new TreeViewItem();
TreeViewItem tempItem1 = new TreeViewItem();
tempItem = (TreeViewItem) treeView1.Items.GetItemAt(0); // Selecting the first of the top level nodes
tempItem1 = (TreeViewItem)tempItem.Items.GetItemAt(0); // Selecting the first child of the first first level node
SelectedCategoryHeaderString = tempItem.Header.ToString(); // gets the header for the first top level node
SelectedCategoryHeaderString = tempItem1.Header.ToString(); // gets the header for the first child node of the first top level node
tempItem.IsExpanded = true; // will expand the first node
use dirname(__FILE__)
in a global configuration file.
For me this worked:
Input df
df = pd.DataFrame({'col x': [1,2,3]})
col x
0 1
1 2
2 3
Function
def f(x):
return pd.Series([x*x, x*x*x])
Create 2 new columns:
df[['square x', 'cube x']] = df['col x'].apply(f)
Output:
col x square x cube x
0 1 1 1
1 2 4 8
2 3 9 27
Sometimes a BEFORE
trigger can be replaced with an AFTER
one, but this doesn't appear to be the case in your situation, for you clearly need to provide a value before the insert takes place. So, for that purpose, the closest functionality would seem to be the INSTEAD OF
trigger one, as @marc_s has suggested in his comment.
Note, however, that, as the names of these two trigger types suggest, there's a fundamental difference between a BEFORE
trigger and an INSTEAD OF
one. While in both cases the trigger is executed at the time when the action determined by the statement that's invoked the trigger hasn't taken place, in case of the INSTEAD OF
trigger the action is never supposed to take place at all. The real action that you need to be done must be done by the trigger itself. This is very unlike the BEFORE
trigger functionality, where the statement is always due to execute, unless, of course, you explicitly roll it back.
But there's one other issue to address actually. As your Oracle script reveals, the trigger you need to convert uses another feature unsupported by SQL Server, which is that of FOR EACH ROW
. There are no per-row triggers in SQL Server either, only per-statement ones. That means that you need to always keep in mind that the inserted data are a row set, not just a single row. That adds more complexity, although that'll probably conclude the list of things you need to account for.
So, it's really two things to solve then:
replace the BEFORE
functionality;
replace the FOR EACH ROW
functionality.
My attempt at solving these is below:
CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
DECLARE @new_super TABLE (
super_id int
);
INSERT INTO super (subtype_discriminator)
OUTPUT INSERTED.super_id INTO @new_super (super_id)
SELECT 'SUB1' FROM INSERTED;
INSERT INTO sub (super_id)
SELECT super_id FROM @new_super;
END;
This is how the above works:
The same number of rows as being inserted into sub1
is first added to super
. The generated super_id
values are stored in a temporary storage (a table variable called @new_super
).
The newly inserted super_id
s are now inserted into sub1
.
Nothing too difficult really, but the above will only work if you have no other columns in sub1
than those you've specified in your question. If there are other columns, the above trigger will need to be a bit more complex.
The problem is to assign the new super_id
s to every inserted row individually. One way to implement the mapping could be like below:
CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
DECLARE @new_super TABLE (
rownum int IDENTITY (1, 1),
super_id int
);
INSERT INTO super (subtype_discriminator)
OUTPUT INSERTED.super_id INTO @new_super (super_id)
SELECT 'SUB1' FROM INSERTED;
WITH enumerated AS (
SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS rownum
FROM inserted
)
INSERT INTO sub1 (super_id, other columns)
SELECT n.super_id, i.other columns
FROM enumerated AS i
INNER JOIN @new_super AS n
ON i.rownum = n.rownum;
END;
As you can see, an IDENTIY(1,1)
column is added to @new_user
, so the temporarily inserted super_id
values will additionally be enumerated starting from 1. To provide the mapping between the new super_id
s and the new data rows, the ROW_NUMBER
function is used to enumerate the INSERTED
rows as well. As a result, every row in the INSERTED
set can now be linked to a single super_id
and thus complemented to a full data row to be inserted into sub1
.
Note that the order in which the new super_id
s are inserted may not match the order in which they are assigned. I considered that a no-issue. All the new super
rows generated are identical save for the IDs. So, all you need here is just to take one new super_id
per new sub1
row.
If, however, the logic of inserting into super
is more complex and for some reason you need to remember precisely which new super_id
has been generated for which new sub
row, you'll probably want to consider the mapping method discussed in this Stack Overflow question:
If you want all the units, not just the biggest one, use one of these 2 methods (based on @Ankish's answer):
Example output: 28 D | 23 H | 59 M | 59 S
+ (NSString *) remaningTime:(NSDate *)startDate endDate:(NSDate *)endDate
{
NSCalendarUnit units = NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
NSDateComponents *components = [[NSCalendar currentCalendar] components:units fromDate: startDate toDate: endDate options: 0];
return [NSString stringWithFormat:@"%ti D | %ti H | %ti M | %ti S", [components day], [components hour], [components minute], [components second]];
}
+ (NSString *) timeFromNowUntil:(NSDate *)endDate
{
return [self remaningTime:[NSDate date] endDate:endDate];
}
The problem lays here:
--This result set has 3 columns
select LOC_id,LOC_locatie,LOC_deelVan_LOC_id from tblLocatie t
where t.LOC_id = 1 -- 1 represents an example
union all
--This result set has 1 columns
select t.LOC_locatie + '>' from tblLocatie t
inner join q parent on parent.LOC_id = t.LOC_deelVan_LOC_id
In order to use union
or union all
number of columns and their types should be identical cross all result sets.
I guess you should just add the column LOC_deelVan_LOC_id
to your second result set
Update:
I use Compare plugin 2 for notepad++ 7.5 and newer versions. Notepad++ 7.5 and newer versions does not have plugin manager. You have to download and install plugins manually. And YES it matters if you use 64bit or 32bit (86x).
So Keep in mind, if you use 64 bit version of Notepad++, you should also use 64 bit version of plugin, and the same valid for 32bit.
I wrote a guideline how to install it:
Note:
It is also possible to drag and drop the plugin.dll
file directly in plugin folder.
64bit:%programfiles%\Notepad++\plugins
32bit:%programfiles(x86)%\Notepad++\plugins
Update Thanks to @TylerH with this update: Notepad++ Now has "Plugin Admin" as a replacement for the old Plugin Manager. But this method (answer) is still valid for adding plugins manually for almost any Notepad++ plugins.
Disclaimer: the link of this guideline refer to my personal web site.
I would like to propose a generalization with awk.
When the file is made by blocks of a fixed size and the lines to delete are repeated for each block, awk can work fine in such a way
awk '{nl=((NR-1)%2000)+1; if ( (nl<714) || ((nl>1025)&&(nl<1029)) ) print $0}'
OriginFile.dat > MyOutputCuttedFile.dat
In this example the size for the block is 2000 and I want to print the lines [1..713] and [1026..1029].
NR
is the variable used by awk to store the current line number.%
gives the remainder (or modulus) of the division of two integers;nl=((NR-1)%BLOCKSIZE)+1
Here we write in the variable nl the line number inside the current block. (see below)||
and &&
are the logical operator OR and AND.print $0
writes the full lineWhy ((NR-1)%BLOCKSIZE)+1:
(NR-1) We need a shift of one because 1%3=1, 2%3=2, but 3%3=0.
+1 We add again 1 because we want to restore the desired order.
+-----+------+----------+------------+
| NR | NR%3 | (NR-1)%3 | (NR-1)%3+1 |
+-----+------+----------+------------+
| 1 | 1 | 0 | 1 |
| 2 | 2 | 1 | 2 |
| 3 | 0 | 2 | 3 |
| 4 | 1 | 0 | 1 |
+-----+------+----------+------------+
Here's another way to do this:
- name: my command
command: echo stuff
when: "'groupname' not in group_names"
group_names
is a magic variable as documented here: https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#accessing-information-about-other-hosts-with-magic-variables :
group_names is a list (array) of all the groups the current host is in.
GitHub Repositories are used to store all the files, folders and other resources which you care about.
Git Project : It is also one of the Resource in Git Repository and main use of it is to manage the projects with a visual board. If you create a project in Git Repository it create a visual board like a Kanban board to manage the project.
In this way, you can have multiple projects in a repository.
If you have the name of the remote, you will be able with git 2.7 (Q4 2015), to use the new git remote get-url

)

I had a big problem with my Samsung S10 Plus as it was not detecded by Android Studio on my Macbook even if I did all what is required to be detected, that is to say:
What I did is to start "Android File Transfer" on my Macbook and the magic happened. A popup appeared on my device asking if I want to authorize an USB access to it. I clicked "Yes, always" and now Android Studio can detect my device on my Mac :)
It to ensure that XHTML validation works correctly when you have JavaScript embedded in your page, rather than externally referenced.
XHTML requires that your page strictly conform to XML markup requirements. Since JavaScript may contain characters with special meaning, you must wrap it in CDATA to ensure that validation does not flag it as malformed.
With HTML pages on the web you can just include the required JavaScript between and tags. When you validate the HTML on your web page the JavaScript content is considered to be CDATA (character data) that is therefore ignored by the validator. The same is not true if you follow the more recent XHTML standards in setting up your web page. With XHTML the code between the script tags is considered to be PCDATA (parsed character data) which is therefore processed by the validator.
Because of this, you can't just include JavaScript between the script tags on your page without 'breaking' your web page (at least as far as the validator is concerned).
You can learn more about CDATA here, and more about XHTML here.
AWK works as a text interpreter that goes linewise for the whole document and that goes fieldwise for each line. Thus $1, $2...$n are references to the fields of each line ($1 is the first field, $2 is the second field, and so on...).
You can define a field separator by using the "-F" switch under the command line or within two brackets with "FS=...".
Now consider the answer of Jürgen:
echo "1: " | awk -F ":" '/1/ {print $1}'
Above the field, boundaries are set by ":" so we have two fields $1 which is "1" and $2 which is the empty space. After comes the regular expression "/1/" that instructs the filter to output the first field only when the interpreter stumbles upon a line containing such an expression (I mean 1).
The output of the "echo" command is one line that contains "1", so the filter will work...
When dealing with the following example:
echo "1: " | awk '/1/ -F ":" {print $1}'
The syntax is messy and the interpreter chose to ignore the part F ":" and switches to the default field splitter which is the empty space, thus outputting "1:" as the first field and there will be not a second field!
The answer of Jürgen contains the good syntax...
Currently (Laravel 5.4) the way to achieve this is:
$model = new Model();
$model->created_at = Carbon::now();
$model->save(['timestamps' => false]);
Have a look at this one. It is the Ternary operator in C#.
bool BooleanValue = (num % 3 != 0) ? true : false;
This is just to show the principle; you can return True or False (or even integer or string) depending on the outcome of something on the left side of the question mark. Nice operator, this.
Three alternatives together:
public bool test1()
{
int num = 21;
bool BooleanValue = (num % 3 != 0) ? true : false;
return BooleanValue;
}
public bool test2()
{
int num = 20;
bool test = (num % 3 != 0);
return test;
}
Even Shorter:
public bool test3()
{
int num = 20;
return (bool)(num % 3 != 0);
}
A UHF RFID reader option for both Android and iOS is available from a company called U Grok It.
It is just UHF, which is "non-NFC enabled Android", if that's what you meant. My apologies if you meant an NFC reader for Android devices that don't have an NFC reader built-in.
Their reader has a range up to 7 meters (~21 feet). It connects via the audio port, not bluetooth, which has the advantage of pairing instantly, securely, and with way less of a power draw.
They have a free native SDK for Android, iOS, Cordova, and Xamarin, as well as an Android keyboard wedge.
Why not keep it simple?
var parseBool = function(str) {
if (typeof str === 'string' && str.toLowerCase() == 'true')
return true;
return (parseInt(str) > 0);
}
The difference in whether you have to instantiate your @InjectMocks
annotated field is in the version of Mockito, not in whether you use the MockitoJunitRunner or MockitoAnnotations.initMocks
. In 1.9, which will also handle some constructor injection of your @Mock
fields, it will do the instantiation for you. In earlier versions, you have to instantiate it yourself.
This is how I do unit testing of my Spring beans. There is no problem. People run into confusion when they want to use Spring configuration files to actually do the injection of the mocks, which is crossing up the point of unit tests and integration tests.
And of course the unit under test is an Impl. You need to test a real concrete thing, right? Even if you declared it as an interface you would have to instantiate the real thing to test it. Now, you could get into spies, which are stub/mock wrappers around real objects, but that should be for corner cases.

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:
declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for
select
row_number() over (order by(select null)) as RowNum
,Data -- you fields
from YourIntTable
open @cur
begin try
fetch last from @cur into @lastNum, @data
fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value
while @i < @lastNum
begin
set @i += 1
--Do your job here
print @data
fetch next from @cur into @rowNum, @data
end
end try
begin catch
close @cur --|
deallocate @cur --|-remove this 3 lines if you do not throw
;throw --|
end catch
close @cur
deallocate @cur
fc. fc is better at handling large files (> 4 GBytes) than Cygwin's diff.
You can do this in single filter step:
requiredCars = cars.stream().filter(c -> c.getName() != null && c.getName().startsWith("M"));
If you don't want to call getName()
several times (for example, it's expensive call), you can do this:
requiredCars = cars.stream().filter(c -> {
String name = c.getName();
return name != null && name.startsWith("M");
});
Or in more sophisticated way:
requiredCars = cars.stream().filter(c ->
Optional.ofNullable(c.getName()).filter(name -> name.startsWith("M")).isPresent());
The closest I have been able to find is called 3taps. 3taps was sued by Craigslist with the result that "access to public data on a public website can be selectively censored by blacklisting certain viewers (i.e. competitors)", and thus states that "3taps will therefore access the very same data exclusively from public sources that retain open and equal access rights to public data".
Another option would be to use the File Explorer in DDMS (Eclipse SDK), you can see the whole file system there and download/upload files to the desired place. That way you don't have to mount and deal with images. Just remember to set your device as USB debuggable (from Developer Tools)

No one mentioned this, but in conjunction to the other responses, you can also get the apk file from your bin directory to your phone or tablet by putting it on a web site and just downloading it.
Your device will complain about installing it after you download it. Your device will advise you or a risk of installing programs from unknown sources and give you the option to bypass the advice.
Your question is very specific. You don't have to pull it from your emulator, just grab the apk file from the bin folder in your project and place it on your real device.
Most people are giving you valuable information for the next step (signing and publishing your apk), you are not required to do that step to get it on your real device.
Downloading it to your real device is a simple method.
After trying many suggestions from various sites and similar questions, what worked for me was to uninstall all Python stuff and reinstall Anaconda only (see https://stackoverflow.com/a/38330088/1083292)
The previous Python installation I had was not only redundant but only caused me trouble.
How about:
>>> string_1 = "(555).555-5555"
>>> string_2 = "(555) 555 - 5555 ext. 5555"
>>> any(c.isalpha() for c in string_1)
False
>>> any(c.isalpha() for c in string_2)
True
Its better if you use validation code to the users input for making it restricted to use symbols and part of code in your input form. If you embeed php in html code your php code have to become on the top to make sure that it is not ignored as comment if a hacker edit the page and add /* in your html code
You can use $pdf->GetX()
and $pdf->GetY()
to get current cooridnates and use them to insert image.
$pdf->Image($image1, 5, $pdf->GetY(), 33.78);
or even
$pdf->Image($image1, 5, null, 33.78);
(ALthough in first case you can add a number to create a bit of a space)
$pdf->Image($image1, 5, $pdf->GetY() + 5, 33.78);
<script src="//code.jquery.com/jquery.min.js"></script>
<script>
function changes() {
$('#link').val('new value');
}
</script>
<button onclick="changes()">a</button>
<input type='text' value='http://www.link.com' id='link'>
these will both work in Python 2.7 and Python 3.x:
>>> l = [1, 2, 3]
>>> print(' '.join(str(x) for x in l))
1 2 3
>>> print(' '.join(map(str, l)))
1 2 3
btw, array
is a reserved word in Python.
A solution for me was to create a UILabel
and add it to the UIButton
as a subview. Finally I added a constraint to center it within the button.
UILabel * myTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 75, 75)];
myTextLabel.text = @"Some Text";
myTextLabel.translatesAutoresizingMaskIntoConstraints = false;
[myButton addSubView:myTextLabel];
// Add Constraints
[[myTextLabel centerYAnchor] constraintEqualToAnchor:myButton.centerYAnchor].active = true;
[[myTextLabel centerXAnchor] constraintEqualToAnchor:myButton.centerXAnchor].active = true;
@D.Wolf -- if Preferences doesn't appear in the drop-down under Tools, there is also an icon in the toolbar that is a direct path to tools -> Preferences, and the Syntax Coloring is on the left-hand side. See the wrench? Just click that.
just use this as a middleware
<?php
namespace App\Http\Middleware;
use Closure;
class CorsMiddleware
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$response = $next($request);
$response->header('Access-Control-Allow-Origin', '*');
$response->header('Access-Control-Allow-Methods', '*');
return $response;
}
}
and register the middleware in your kernel file on this path app/Http/Kernel.php
in which group that you prefer and everything will be fine
If you are familiar with using System.Windows.Forms class then you can just add a reference of System.Windows.Forms class to your project:
Solution Explorer -> References -> Add References... -> ( Assemblies : Framework ) -> scroll down and check System.Windows.Forms assembly -> OK.
Now you can add using System.Windows.Forms; statement and use screen in your wpf project just like before.
Set the value it will set it as selected option for dropdown:
$("#salesrep").val("Bruce Jones");
If it still not working:
I prefer xargs
find . -type f | xargs grep -I "needle text"
if your filenames are weird look up using the -0 options:
find . -type f -print0 | xargs -0 grep -I "needle text"
You could try using a Polyfill. The following Polyfill was published in 2019 and did the trick for me. It assigns the Promise function to the window object.
used like: window.Promise
https://www.npmjs.com/package/promise-polyfill
If you want more information on Polyfills check out the following MDN web doc https://developer.mozilla.org/en-US/docs/Glossary/Polyfill
This is almost like the other answer but you don't need a scatter
plot at all, you can simply specify a scatter-plot-like format (fmt
-parameter) for errorbar
:
import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [1, 4, 9, 16]
e = [0.5, 1., 1.5, 2.]
plt.errorbar(x, y, yerr=e, fmt='o')
plt.show()
Result:
A list of the avaiable fmt
parameters can be found for example in the plot
documentation:
character description
'-' solid line style
'--' dashed line style
'-.' dash-dot line style
':' dotted line style
'.' point marker
',' pixel marker
'o' circle marker
'v' triangle_down marker
'^' triangle_up marker
'<' triangle_left marker
'>' triangle_right marker
'1' tri_down marker
'2' tri_up marker
'3' tri_left marker
'4' tri_right marker
's' square marker
'p' pentagon marker
'*' star marker
'h' hexagon1 marker
'H' hexagon2 marker
'+' plus marker
'x' x marker
'D' diamond marker
'd' thin_diamond marker
'|' vline marker
'_' hline marker
Any of the following should work
pip --version

Wasim's answer lead me in the right direction but I had to make some changes to get it working for my current project. I am using this function in a fragment and calling it on button click.
fun showPostDialog(title: String) {
val alert = AlertDialog.Builder(activity)
val edittext = EditText(activity)
edittext.hint = "Enter Name"
edittext.maxLines = 1
var layout = activity?.let { FrameLayout(it) }
//set padding in parent layout
// layout.isPaddingRelative(45,15,45,0)
layout?.setPadding(45,15,45,0)
alert.setTitle(title)
layout?.addView(edittext)
alert.setView(layout)
alert.setPositiveButton(getString(R.string.label_save), DialogInterface.OnClickListener {
dialog, which ->
run {
val qName = edittext.text.toString()
showToast("Posted to leaderboard successfully")
view?.hideKeyboard()
}
})
alert.setNegativeButton(getString(R.string.label_cancel), DialogInterface.OnClickListener {
dialog, which ->
run {
dialog.dismiss()
}
})
alert.show()
}
fun View.hideKeyboard() {
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(windowToken, 0)
}
fun showToast(message: String) {
Toast.makeText(activity, message, Toast.LENGTH_LONG).show()
}
I hope it helps someone else in the near future. Happy coding!
Module named importlib
allow to access to import internals. Especially, it provide function importlib.reload()
:
import importlib
importlib.reload(my_module)
In contrary of %autoreload
, importlib.reload()
also reset global variables set in module. In most cases, it is what you want.
importlib
is only available since Python 3.1. For older version, you have to use module imp
.
chunks = [data[100*i:100*(i+1)] for i in range(len(data)/100 + 1)]
This is equivalent to the accepted answer. For example, shortening to batches of 10 for readability:
data = range(35)
print [data[x:x+10] for x in xrange(0, len(data), 10)]
print [data[10*i:10*(i+1)] for i in range(len(data)/10 + 1)]
Outputs:
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]

The standard Pinterest button code (which you can generate here), is an <a>
tag wrapping an <img>
of the Pinterest button.
If you don't include the pinit.js
script on your page, this <a>
tag will work "as-is". You could improve the experience by registering your own click handler on these tags that opens a new window with appropriate dimensions, or at least adding target="_blank"
to the tag to make it open clicks in a new window.
The tag syntax would look like:
<a href="http://pinterest.com/pin/create/button/?url={URI-encoded URL of the page to pin}&media={URI-encoded URL of the image to pin}&description={optional URI-encoded description}" class="pin-it-button" count-layout="horizontal">
<img border="0" src="//assets.pinterest.com/images/PinExt.png" title="Pin It" />
</a>
If using the JavaScript versions of sharing buttons are ruining your page load times, you can improve your site by using asynchronous loading methods. For an example of doing this with the Pinterest button, check out my GitHub Pinterest button project with an improved HTML5 syntax.

Few years ago, when working on loyality program, we had an issue with the amount of points given to customers. The issue was related to casting/converting double to int.
In code below:
double d = 13.6;
int i1 = Convert.ToInt32(d);
int i2 = (int)d;
does i1 == i2 ?
It turns out that i1 != i2. Because of different rounding policies in Convert and cast operator the actual values are:
i1 == 14
i2 == 13
It's always better to call Math.Ceiling() or Math.Floor() (or Math.Round with MidpointRounding that meets our requirements)
int i1 = Convert.ToInt32( Math.Ceiling(d) );
int i2 = (int) Math.Ceiling(d);
a[len(a):]
- This gets you the length of a to the end. It selects a range. If you reverse a[:len(a)]
it will get you the beginning to whatever is len(a)
.
I found that the only option that worked for me was
font-size:0;
I was also using overflow
and white-space: nowrap;
float: left;
seems to mess things up
Considering background-images can't be animated, I created a little SCSS mixin allowing to transition between 2 different background-images using pseudo selectors before and after. They are at different z-index layers. The one that is ahead starts with opacity 0 and becomes visible with hover.
You can use it the same approach for creating animations with linear-gradients too.
@mixin bkg-img-transition( $bkg1, $bkg2, $transTime:0.5s ){
position: relative;
z-index: 100;
&:before, &:after {
background-size: cover;
content: '';
display: block;
height: 100%;
position: absolute;
top: 0; left: 0;
width: 100%;
transition: opacity $transTime;
}
&:before {
z-index: -101;
background-image: url("#{$bkg1}");
}
&:after {
z-index: -100;
opacity: 0;
background-image: url("#{$bkg2}");
}
&:hover {
&:after{
opacity: 1;
}
}
}
Now you can simply use it with
@include bkg-img-transition("https://picsum.photos/300/300/?random","https://picsum.photos/g/300/300");
You can check it out here: https://jsfiddle.net/pablosgpacheco/01rmg0qL/

return a * np.exp(b * x) + c
def func_log(x, a, b, c):
"""Return values from a general log function."""
return a * np.log(b * x) + c
# Helper
def generate_data(func, *args, jitter=0):
"""Return a tuple of arrays with random data along a general function."""
xs = np.linspace(1, 5, 50)
ys = func(xs, *args)
noise = jitter * np.random.normal(size=len(xs)) + jitter
xs = xs.reshape(-1, 1) # xs[:, np.newaxis]
ys = (ys + noise).reshape(-1, 1)
return xs, ys
transformer = FunctionTransformer(np.log, validate=True)
Code
Fit exponential data
# Data
x_samp, y_samp = generate_data(func_exp, 2.5, 1.2, 0.7, jitter=3)
y_trans = transformer.fit_transform(y_samp) # 1
# Regression
regressor = LinearRegression()

) and fit to original dataAssuming our data follows an exponential trend, a general equation+ may be:
We can linearize the latter equation (e.g. y = intercept + slope * x) by taking the log:
Given a linearized equation++ and the regression parameters, we could calculate:
A
via intercept (ln(A)
)B
via slope (B
)Summary of Linearization Techniques
Relationship | Example | General Eqn. | Altered Var. | Linearized Eqn.
-------------|------------|----------------------|----------------|------------------------------------------
Linear | x | y = B * x + C | - | y = C + B * x
Logarithmic | log(x) | y = A * log(B*x) + C | log(x) | y = C + A * (log(B) + log(x))
Exponential | 2**x, e**x | y = A * exp(B*x) + C | log(y) | log(y-C) = log(A) + B * x
Power | x**2 | y = B * x**N + C | log(x), log(y) | log(y-C) = log(B) + N * log(x)
+Note: linearizing exponential functions works best when the noise is small and C=0. Use with caution.
++Note: while altering x data helps linearize exponential data, altering y data helps linearize log data.
You can also use BigInteger for variable length bytes. You can convert it to Long, Integer or Short, whichever suits your needs.
new BigInteger(bytes).intValue();
or to denote polarity:
new BigInteger(1, bytes).intValue();
If your Python datetime object is timezone-aware than you should be careful to avoid errors around DST transitions (or changes in UTC offset for other reasons):
from datetime import datetime, timedelta
from tzlocal import get_localzone # pip install tzlocal
DAY = timedelta(1)
local_tz = get_localzone() # get local timezone
now = datetime.now(local_tz) # get timezone-aware datetime object
day_ago = local_tz.normalize(now - DAY) # exactly 24 hours ago, time may differ
naive = now.replace(tzinfo=None) - DAY # same time
yesterday = local_tz.localize(naive, is_dst=None) # but elapsed hours may differ
In general, day_ago
and yesterday
may differ if UTC offset for the local timezone has changed in the last day.
For example, daylight saving time/summer time ends on Sun 2-Nov-2014 at 02:00:00 A.M. in America/Los_Angeles timezone therefore if:
import pytz # pip install pytz
local_tz = pytz.timezone('America/Los_Angeles')
now = local_tz.localize(datetime(2014, 11, 2, 10), is_dst=None)
# 2014-11-02 10:00:00 PST-0800
then day_ago
and yesterday
differ:
day_ago
is exactly 24 hours ago (relative to now
) but at 11 am, not at 10 am as now
yesterday
is yesterday at 10 am but it is 25 hours ago (relative to now
), not 24 hours.pendulum
module handles it automatically:
>>> import pendulum # $ pip install pendulum
>>> now = pendulum.create(2014, 11, 2, 10, tz='America/Los_Angeles')
>>> day_ago = now.subtract(hours=24) # exactly 24 hours ago
>>> yesterday = now.subtract(days=1) # yesterday at 10 am but it is 25 hours ago
>>> (now - day_ago).in_hours()
24
>>> (now - yesterday).in_hours()
25
>>> now
<Pendulum [2014-11-02T10:00:00-08:00]>
>>> day_ago
<Pendulum [2014-11-01T11:00:00-07:00]>
>>> yesterday
<Pendulum [2014-11-01T10:00:00-07:00]>

For strings, forget about using WHENCE: use f.seek(0) to position at beginning of file and f.seek(len(f)+1) to position at the end of file. Use open(file, "r+") to read/write anywhere in a file. If you use "a+" you'll only be able to write (append) at the end of the file regardless of where you position the cursor.
Actually, the problem here is the use of ReadContentAsObject. Unfortunately, this method does not live up to its expectations; while it should detect the most appropirate type for the value, it actually returns a string, no matter what(this can be verified using Reflector).
However, in your specific case, you already know the type you want to cast to, therefore i would say you are using the wrong method.
Try using ReadContentAs instead, it's exactly what you need.
private static T ReadData<T>(XmlReader reader, string value)
{
reader.MoveToAttribute(value);
object readData = reader.ReadContentAs(typeof(T), null);
return (T)readData;
}
if user doesn't have any qr reader, what will happen to the application? if it crashes, may i ask user to download for example QrDroid and after that use it?
Interestingly, Google now introduced Mobile Vision APIs, they are integrated in play services itself.
In your Gradle file just add:
compile 'com.google.android.gms:play-services-vision:11.4.0'
Taken from this QR code tutorial.
UPDATE 2020:
Now QR code scanning is also a part of ML Kit, so you can bundle the model inside the app and use it by integrating the following gradle dependency:
dependencies {
// ...
// Use this dependency to bundle the model with your app
implementation 'com.google.mlkit:barcode-scanning:16.0.3'
}
Or you can use the following gradle dependency to dynamically download the models from Google Play Services:
dependencies {
// ...
// Use this dependency to use the dynamically downloaded model in Google Play Services
implementation 'com.google.android.gms:play-services-mlkit-barcode-scanning:16.1.2'
}
Taken from this link.
In servers, you may like to send RST
instead of FIN
when disconnecting misbehaving clients. That skips FIN-WAIT
followed by TIME-WAIT
socket states in the server, which prevents from depleting server resources, and, hence, protects from this kind of denial-of-service attack.
Just figured this out on my own for showing a countdown but it would also work for a percentage.
import time
#Number of seconds to wait
i=15
#Until seconds has reached zero
while i > -1:
#Ensure string overwrites the previous line by adding spaces at end
print("\r{} seconds left. ".format(i),end='')
time.sleep(1)
i-=1
print("") #Adds newline after it's done
As long as whatever comes after '/r' is the same length or longer (including spaces) than the previous string, it will overwrite it on the same line. Just make sure you include the end='' otherwise it will print to a newline. Hope that helps!
As mentioned above, BOOL is a signed char. bool - type from C99 standard (int).
BOOL - YES/NO. bool - true/false.
See examples:
bool b1 = 2;
if (b1) printf("REAL b1 \n");
if (b1 != true) printf("NOT REAL b1 \n");
BOOL b2 = 2;
if (b2) printf("REAL b2 \n");
if (b2 != YES) printf("NOT REAL b2 \n");
And result is
REAL b1
REAL b2
NOT REAL b2
Note that bool != BOOL. Result below is only ONCE AGAIN - REAL b2
b2 = b1;
if (b2) printf("ONCE AGAIN - REAL b2 \n");
if (b2 != true) printf("ONCE AGAIN - NOT REAL b2 \n");
If you want to convert bool to BOOL you should use next code
BOOL b22 = b1 ? YES : NO; //and back - bool b11 = b2 ? true : false;
So, in our case:
BOOL b22 = b1 ? 2 : NO;
if (b22) printf("ONCE AGAIN MORE - REAL b22 \n");
if (b22 != YES) printf("ONCE AGAIN MORE- NOT REAL b22 \n");
And so.. what we get now? :-)
https://github.com/cscott/jsshaper implements a translator from JavaScript 1.8 to ECMAScript 5.1, which would allow you to use 'for each' in code running on webkit or node.
My .vimrc includes (among other, more usefull things) the following line:
set statusline=%2*%n\|%<%*%-.40F%2*\|\ %2*%M\ %3*%=%1*\ %1*%2.6l%2*x%1*%1.9(%c%V%)%2*[%1*%P%2*]%1*%2B
I got bored while learning for my high school finals.
Here's a simple example using urllib2 that does a basic authentication against GitHub's API.
import urllib2
u='username'
p='userpass'
url='https://api.github.com/users/username'
# simple wrapper function to encode the username & pass
def encodeUserData(user, password):
return "Basic " + (user + ":" + password).encode("base64").rstrip()
# create the request object and set some headers
req = urllib2.Request(url)
req.add_header('Accept', 'application/json')
req.add_header("Content-type", "application/x-www-form-urlencoded")
req.add_header('Authorization', encodeUserData(u, p))
# make the request and print the results
res = urllib2.urlopen(req)
print res.read()
Furthermore if you wrap this in a script and run it from a terminal you can pipe the response string to 'mjson.tool' to enable pretty printing.
>> basicAuth.py | python -mjson.tool
One last thing to note, urllib2 only supports GET & POST requests.
If you need to use other HTTP verbs like DELETE, PUT, etc you'll probably want to take a look at PYCURL
If you're not sure your input is going to be a Numpy array, you can use asarray
with dtype=int
instead of astype
:
>>> np.asarray([1,2,3,4], dtype=int)
array([1, 2, 3, 4])
If the input array already has the correct dtype, asarray
avoids the array copy while astype
does not (unless you specify copy=False
):
>>> a = np.array([1,2,3,4])
>>> a is np.asarray(a) # no copy :)
True
>>> a is a.astype(int) # copy :(
False
>>> a is a.astype(int, copy=False) # no copy :)
True
Some good answers already make use of calendar but the effect of setting the locale hasn't been mentioned yet.
Calendar set month names according to the current locale, for exemple in French:
import locale
import calendar
locale.setlocale(locale.LC_ALL, 'fr_FR')
assert calendar.month_name[1] == 'janvier'
assert calendar.month_abbr[1] == 'jan'
If you plan on using setlocale
in your code, make sure to read the tips and caveats and extension writer sections from the documentation. The example shown here is not representative of how it should be used. In particular, from these two sections:
It is generally a bad idea to call setlocale() in some library routine, since as a side effect it affects the entire program […]
Extension modules should never call setlocale() […]
Got this off an Android forum where I asked the same question. Hope this helps somebody else.
On a terminal emulator on the phone:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Then on the cmd prompt, do the adb push
The appref-ms file does not point to the exe. When you hit that shortcut, it invokes the deployment manifest at the deployment provider url and checks for updates. It checks the application manifest (yourapp.exe.manifest) to see what files to download, and this file contains the definition of the entry point (i.e. the exe).
