The inclusion of your comparison class (or more specifically the AsEnumerable
call you needed to use to get it to work) meant that the sorting logic went from being based on the database server to being on the database client (your application). This meant that your client now needs to retrieve and then process a larger number of records, which will always be less efficient that performing the lookup on the database where the approprate indexes can be used.
You should try to develop a where clause that satisfies your requirements instead, see Using an IEqualityComparer with a LINQ to Entities Except clause for more details.
For Spring 2.5, there's no @Primary
. The only way is to use @Qualifier
.
If you're going to compile a 64bit version(x86_64) of php use: /usr/lib64/
For architectures (i386 ... i686) use /usr/lib/
I recommend compiling php to the same architecture as apache. As you're using a 64bit linux i asume your apache is also compiled for x86_64.
Something like this would work.
def relative_time(start_time)
diff_seconds = Time.now - start_time
case diff_seconds
when 0 .. 59
puts "#{diff_seconds} seconds ago"
when 60 .. (3600-1)
puts "#{diff_seconds/60} minutes ago"
when 3600 .. (3600*24-1)
puts "#{diff_seconds/3600} hours ago"
when (3600*24) .. (3600*24*30)
puts "#{diff_seconds/(3600*24)} days ago"
else
puts start_time.strftime("%m/%d/%Y")
end
end
In the end, something does have to be removed. I would like to add to the other answers: be sure to check for conflicts. For me, the EMF (Eclipse Modeling Framework) had somehow gotten out of hand as I had multiple versions listed in windows/preferences. Removing the conflict allowed for my updates to proceed as normal.
function escapeRegExp(string) {
return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string

Example
escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");
>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "
(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

If you package it as a single jar and it's non web app try to load app context as below.
@SpringBootApplication
ApplicationContext ctx = new AnnotationConfigApplicationContext(Main.class);
Or use below plugin to package as a single jar
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
you can specify the external configs by using below command to run
java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
Note that if you are passing the properties as arguments then don't include @PropertySource("classpath:test.properties")
it will override the parameters
Without an ORDER BY
the whole idea of TOP
doesn't make much sense. You need to have a consistent definition of which direction is "up" and which is "down" for the concept of top to be meaningful.
Nonetheless SQL Server allows it but doesn't guarantee a deterministic result.
The UPDATE TOP
syntax in the accepted answer does not support an ORDER BY
clause but it is possible to get deterministic semantics here by using a CTE or derived table to define the desired sort order as below.
;WITH CTE AS
(
SELECT TOP 100 *
FROM T1
ORDER BY F2
)
UPDATE CTE SET F1='foo'
Unfortunately, you're out of luck here.
There is inherit
to copy a certain value from a parent to its children, but there is no property the other way round (which would involve another selector to decide which style to revert).
You will have to revert style changes manually:
div { color: green; }
form div { color: red; }
form div div.content { color: green; }
If you have access to the markup, you can add several classes to style precisely what you need:
form div.sub { color: red; }
form div div.content { /* remains green */ }
Edit: The CSS Working Group is up to something:
div.content {
all: revert;
}
No idea, when or if ever this will be implemented by browsers.
Edit 2: As of March 2015 all modern browsers but Safari and IE/Edge have implemented it: https://twitter.com/LeaVerou/status/577390241763467264 (thanks, @Lea Verou!)
Edit 3: default

Yes include the first file into the second. That's all.
See an example below,
File1.php :
<?php
function first($int, $string){ //function parameters, two variables.
return $string; //returns the second argument passed into the function
}
?>
Now Using include
(http://php.net/include) to include the File1.php
to make its content available for use in the second file:
File2.php :
<?php
include 'File1.php';
echo first(1,"omg lol"); //returns omg lol;
?>
I was running into a similar error in pywikipediabot. The .decode
method is a step in the right direction but for me it didn't work without adding 'ignore'
:
ignore_encoding = lambda s: s.decode('utf8', 'ignore')
Ignoring encoding errors can lead to data loss or produce incorrect output. But if you just want to get it done and the details aren't very important this can be a good way to move faster.
pd.datetime.now().strftime("%d/%m/%Y")
this will give output as '11/02/2019'
you can use add time if you want
pd.datetime.now().strftime("%d/%m/%Y %I:%M:%S")
this will give output as '11/02/2019 11:08:26'
While executing the job we need to pass Job parameters as follows:
JobParameters jobParameters= new JobParametersBuilder().addString("file.name", "filename.txt").toJobParameters();
JobExecution execution = jobLauncher.run(job, jobParameters);
by using the expression language we can import the value as follows:
#{jobParameters['file.name']}
Try this:
df.loc[len(df)]=['8/19/2014','Jun','Fly','98765']
Warning: this method works only if there are no "holes" in the index. For example, suppose you have a dataframe with three rows, with indices 0, 1, and 3 (for example, because you deleted row number 2). Then, len(df) = 3, so by the above command does not add a new row - it overrides row number 3.
As of PHP 8.0 there are two new methods implemented: str_starts_with
and str_ends_with
. They are case-sensitive though. The functions return true or false.
$str = 'apples';
var_dump(str_starts_with($str, 'a')); // bool(true)
var_dump(str_starts_with($str, 'A')); // bool(false)
var_dump(str_ends_with($str, 's')); // bool(true)
var_dump(str_ends_with($str, 'S')); // bool(false)

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace); CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession); CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);
This is what I came up with for a gradle build script:
task doLast {
ext.FindFile = { list, curPath ->
def files = file(curPath).listFiles().sort()
files.each { File file ->
if (file.isFile()) {
list << file
}
else {
list << file // If you want the directories in the list
list = FindFile( list, file.path)
}
}
return list
}
def list = []
def theFile = FindFile(list, "${project.projectDir}")
list.each {
println it.path
}
}
I've been trying to activate 'active' class manually with javascript. It's not as usable as a complete library, but for easy cases seems to be enough:
var button = $('#myToggleButton');
button.on('click', function () {
$(this).toggleClass('active');
});
If you think carefully, 'active' class is used by bootstrap when the button is being pressed, not before or after that (our case), so there's no conflict in reuse the same class.
Try this example and tell me if it fails: http://jsbin.com/oYoSALI/1/edit?html,js,output
like Answers above, if you do bootstrap 4 just add few line of css to .carousel , carousel-inner ,carousel-item and img as follows
.carousel .carousel-inner{
height:500px
}
.carousel-inner .carousel-item img{
min-height:200px;
//prevent it from stretch in screen size < than 768px
object-fit:cover
}
@media(max-width:768px){
.carousel .carousel-inner{
//prevent it from adding a white space between carousel and container elements
height:auto
}
}
override func viewDidLoad() {
super.viewDidLoad()
self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(tap)))
}
func tap(sender: UITapGestureRecognizer){
print("tapped")
view.endEditing(true)
}
Try this,It's Working
Please Learn how Chart.js (version 2 here) works and do it for whatever attribute you want:
<canvas id="your-chart-id" height="your-height" width="your-width"></canvas>
2.Please suppose you have a javascript code that fills your chart first time (for example when page is loaded):
var ctx = document.getElementById('your-chart-id').getContext('2d');
var chartInstance = new Chart(ctx, {
type: 'bar',
data: {
labels: your-lables-array,
datasets: [{
data: your-data-array,
/*you can create random colors dynamically by ColorHash library [https://github.com/zenozeng/color-hash]*/
backgroundColor: your-lables-array.map(function (item) {
return colorHash.hex(item);
})
}]
},
options: {
maintainAspectRatio: false,
scales: {
yAxes: [ { ticks: {beginAtZero: true} } ]
},
title: {display: true, fontSize: 16, text: 'chart title'},
legend: {display: false}
}
});
Please suppose you want to update fully your dataset.
It is very simple. Please look at the above code and see how is the path from your chart variable to data and then follow the below path:
chartInstance
var.data node
inside the chartInstance
.datasets node
inside the data node
.datasets node
is an array. so you have to
specify which element of this array you want. here we have only one
element in the datasets node
. so we use datasets[0]
datasets[0]
data node
inside in the datasets[0]
.
This steps gives you chartInstance.data.datasets[0].data
and you can set new data and update the chart:
chartInstance.data.datasets[0].data = NEW-your-data-array
//finally update chart var:
chartInstance.update();
private void button2_Click(object sender, EventArgs e)

}
static void XML_Array(Dictionary<string, string> Data_Array)

This worked for me but only after forcing the specific verbs to be handled by the default handler.

<add path="*" verb="TRACE" type="System.Web.DefaultHttpHandler" validate="true"/>
<add path="*" verb="HEAD" type="System.Web.DefaultHttpHandler" validate="true"/>
You still use the same configuration as you have above, but also force the verbs to be handled with the default handler and validated. Source: http://forums.asp.net/t/1311323.aspx
An easy way to test is just to deny GET and see if your site loads.
My examples are in Clojure, but should be fairly easy to translate to any language.
Given this function that StackOverflow
s for large values of n:
(defn factorial [n]
(if (< n 2)
1
(*' n (factorial (dec n)))))
we can define a version that uses its own stack in the following manner:
(defn factorial [n]
(loop [n n
stack []]
(if (< n 2)
(return 1 stack)
;; else loop with new values
(recur (dec n)
;; push function onto stack
(cons (fn [n-1!]
(*' n n-1!))
stack)))))
where return
is defined as:
(defn return
[v stack]
(reduce (fn [acc f]
(f acc))
v
stack))
This works for more complex functions too, for example the ackermann function:
(defn ackermann [m n]
(cond
(zero? m)
(inc n)
(zero? n)
(recur (dec m) 1)
:else
(recur (dec m)
(ackermann m (dec n)))))
can be transformed into:
(defn ackermann [m n]
(loop [m m
n n
stack []]
(cond
(zero? m)
(return (inc n) stack)
(zero? n)
(recur (dec m) 1 stack)
:else
(recur m
(dec n)
(cons #(ackermann (dec m) %)
stack)))))
Internally, SQL Server treats an inline table valued function much like it would a view and treats a multi-statement table valued function similar to how it would a stored procedure.
When an inline table-valued function is used as part of an outer query, the query processor expands the UDF definition and generates an execution plan that accesses the underlying objects, using the indexes on these objects.
For a multi-statement table valued function, an execution plan is created for the function itself and stored in the execution plan cache (once the function has been executed the first time). If multi-statement table valued functions are used as part of larger queries then the optimiser does not know what the function returns, and so makes some standard assumptions - in effect it assumes that the function will return a single row, and that the returns of the function will be accessed by using a table scan against a table with a single row.
Where multi-statement table valued functions can perform poorly is when they return a large number of rows and are joined against in outer queries. The performance issues are primarily down to the fact that the optimiser will produce a plan assuming that a single row is returned, which will not necessarily be the most appropriate plan.
As a general rule of thumb we have found that where possible inline table valued functions should be used in preference to multi-statement ones (when the UDF will be used as part of an outer query) due to these potential performance issues.
What's you've got there should be fine to work, but there is no actual "Is Mobile/Tablet" media query so you're always going to be stuck.
There are media queries for common breakpoints , but with the ever changing range of devices they're not guaranteed to work moving forwards.
The idea is that your site maintains the same brand across all sizes, so you should want the styles to cascade across the breakpoints and only update the widths and positioning to best suit that viewport.
To further the answer above, using Modernizr with a no-touch test will allow you to target touch devices which are most likely tablets and smart phones, however with the new releases of touch based screens that is not as good an option as it once was.
As Mikkel posted before Collections.rotate is a simple way. I'm using this method for moving items up- and downward in a List.
public static <T> void moveItem(int sourceIndex, int targetIndex, List<T> list) {
if (sourceIndex <= targetIndex) {
Collections.rotate(list.subList(sourceIndex, targetIndex + 1), -1);
} else {
Collections.rotate(list.subList(targetIndex, sourceIndex + 1), 1);
}
}
values = ['A', 'B', 'C', 'D', 'E']
values[0] # returns 'A'
values[2] # returns 'C'
# etc.
Expanding on eumiro's comment, normally tuple(l)
will convert a list l
into a tuple:
In [1]: l = [4,5,6]
In [2]: tuple
Out[2]: <type 'tuple'>
In [3]: tuple(l)
Out[3]: (4, 5, 6)
However, if you've redefined tuple
to be a tuple rather than the type
tuple
:
In [4]: tuple = tuple(l)
In [5]: tuple
Out[5]: (4, 5, 6)
then you get a TypeError since the tuple itself is not callable:
In [6]: tuple(l)
TypeError: 'tuple' object is not callable
You can recover the original definition for tuple
by quitting and restarting your interpreter, or (thanks to @glglgl):
In [6]: del tuple
In [7]: tuple
Out[7]: <type 'tuple'>
One solution is to use matplotlib histogram directly on each grouped data frame. You can loop through the groups obtained in a loop. Each group is a dataframe. And you can create a histogram for each one.
from pandas import DataFrame
import numpy as np
x = ['A']*300 + ['B']*400 + ['C']*300
y = np.random.randn(1000)
df = DataFrame({'Letter':x, 'N':y})
grouped = df.groupby('Letter')
for group in grouped:
figure()
matplotlib.pyplot.hist(group[1].N)
show()
A .jar file contains compiled code (*.class files) and other data/resources related to that code. It enables you to bundle multiple files into a single archive file. It also contains metadata. Since it is a zip file it is capable of compressing the data that you put into it.
Couple of things i found useful.
http://www.skylit.com/javamethods/faqs/createjar.html
http://docs.oracle.com/javase/tutorial/deployment/jar/basicsindex.html
The book OSGi in practice defines JAR files as, "JARs are archive files based on the ZIP file format, allowing many files to be aggregated into a single file. Typically the files contained in the archive are a mixture of compiled Java class files and resource files such as images and documents. Additionally the specification defines a standard location within a JAR archive for metadata — the META-INF folder — and several standard file names and formats within that directly, most important of which is the MANIFEST.MF file."
map = your hashmap;
List<Map.Entry<String, Integer>> list = new LinkedList<Map.Entry<String, Integer>>(map.entrySet());
Collections.sort(list, new cm());//IMP
HashMap<String, Integer> sorted = new LinkedHashMap<String, Integer>();
for(Map.Entry<String, Integer> en: list){
sorted.put(en.getKey(),en.getValue());
}
System.out.println(sorted);//sorted hashmap
create new class
class cm implements Comparator<Map.Entry<String, Integer>>{
@Override
public int compare(Map.Entry<String, Integer> a,
Map.Entry<String, Integer> b)
{
return (a.getValue()).compareTo(b.getValue());
}
}
Since seaborn also uses matplotlib to do its plotting you can easily combine the two. If you only want to adopt the styling of seaborn the set_style
function should get you started:
import matplotlib.pyplot as plt
import numpy as np
import seaborn as sns
sns.set_style("darkgrid")
plt.plot(np.cumsum(np.random.randn(1000,1)))
plt.show()

Jonas's answer is good, but I had to modify it slightly to get every piece of text on the screen to change:

Lets assume you have two array, one for movie and one for genre
Just use the filter as: filter:{genres: genres.type}
Here genres being the array and type has value for genre
There's no proper way to cast this to int
in general case. C99 standard library provides intptr_t
and uintptr_t
typedefs, which are supposed to be used whenever the need to perform such a cast comes about. If your standard library (even if it is not C99) happens to provide these types - use them. If not, check the pointer size on your platform, define these typedefs accordingly yourself and use them.
In addition to the existing answer it is possible to set a default option as follows:
echo off
ECHO A current build of Test Harness exists.
set delBuild=n
set /p delBuild=Delete preexisting build [y/n] (default - %delBuild%)?:
This allows users to simply hit "Enter" if they want to enter the default.
After clicking on the magic wand icon to infer constraints:
1) In Projects window, go to Gradle Scripts > build.gradle (Module:app)
2) Scroll down to dependencies
3) Look for implementation 'com.android.support:appcompat-v7:28.0.0-beta03'
4) Change this line to implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
5) A banner should pop up at the top of the window, click Sync Now in the right corner.
This works for Android Studio v3.1 click for image of edit to build.gradle file
It should be noted that the documentation recommends using a Layout
rather than Canvas.drawText
directly. My full answer about using a StaticLayout
is here, but I will provide a summary below.
String text = "This is some text.";
TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);
int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);
Here is a fuller example in the context of a custom view:
public class MyView extends View {
String mText = "This is some text.";
TextPaint mTextPaint;
StaticLayout mStaticLayout;
// use this constructor if creating MyView programmatically
public MyView(Context context) {
super(context);
initLabelView();
}
// this constructor is used when created from xml
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
initLabelView();
}
private void initLabelView() {
mTextPaint = new TextPaint();
mTextPaint.setAntiAlias(true);
mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
mTextPaint.setColor(0xFF000000);
// default to a single line of text
int width = (int) mTextPaint.measureText(mText);
mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
// New API alternate
//
// StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
// .setAlignment(Layout.Alignment.ALIGN_NORMAL)
// .setLineSpacing(1, 0) // multiplier, add
// .setIncludePad(false);
// mStaticLayout = builder.build();
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Tell the parent layout how big this view would like to be
// but still respect any requirements (measure specs) that are passed down.
// determine the width
int width;
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
if (widthMode == MeasureSpec.EXACTLY) {
width = widthRequirement;
} else {
width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
if (widthMode == MeasureSpec.AT_MOST) {
if (width > widthRequirement) {
width = widthRequirement;
// too long for a single line so relayout as multiline
mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
}
}
}
// determine the height
int height;
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
if (heightMode == MeasureSpec.EXACTLY) {
height = heightRequirement;
} else {
height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
if (heightMode == MeasureSpec.AT_MOST) {
height = Math.min(height, heightRequirement);
}
}
// Required call: set width and height
setMeasuredDimension(width, height);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
// do as little as possible inside onDraw to improve performance
// draw the text on the canvas after adjusting for padding
canvas.save();
canvas.translate(getPaddingLeft(), getPaddingTop());
mStaticLayout.draw(canvas);
canvas.restore();
}
}
ftplib now supports context managers so I guess it can be made even easier
from ftplib import FTP
from pathlib import Path
file_path = Path('kitten.jpg')
with FTP('server.address.com', 'USER', 'PWD') as ftp, open(file_path, 'rb') as file:
ftp.storbinary(f'STOR {file_path.name}', file)
No need to close the file or the session
Possibly the fastest solution is to operate in plain Python:
Series(
map(
'_'.join,
df.values.tolist()
# when non-string columns are present:
# df.values.astype(str).tolist()
),
index=df.index
)
Comparison against @MaxU answer (using the big
data frame which has both numeric and string columns):
%timeit big['bar'].astype(str) + '_' + big['foo'] + '_' + big['new']
# 29.4 ms ± 1.08 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
%timeit Series(map('_'.join, big.values.astype(str).tolist()), index=big.index)
# 27.4 ms ± 2.36 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
Comparison against @derchambers answer (using their df
data frame where all columns are strings):
from functools import reduce
def reduce_join(df, columns):
slist = [df[x] for x in columns]
return reduce(lambda x, y: x + '_' + y, slist[1:], slist[0])
def list_map(df, columns):
return Series(
map(
'_'.join,
df[columns].values.tolist()
),
index=df.index
)
%timeit df1 = reduce_join(df, list('1234'))
# 602 ms ± 39 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
%timeit df2 = list_map(df, list('1234'))
# 351 ms ± 12.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

You are using an inline table value function. Therefore you must use Select * From function. If you want to use select function() you must use a scalar function.

In my case, the issue was due to WAMP using a different php.ini for CLI than Apache, so your settings made through the WAMP menu don't apply to CLI. Just modify the CLI php.ini and it works.
The command on OSX should be exactly the same as it is Unix under the pretty UI.

There is an option to disable cross-origin restrictions in Safari 9, different from local file restrictions as mentioned above.
MVVM Model-View ViewModel is similar to MVC, Model-View Controller
The controller is replaced with a ViewModel. The ViewModel sits below the UI layer. The ViewModel exposes the data and command objects that the view needs. You could think of this as a container object that view goes to get its data and actions from. The ViewModel pulls its data from the model.
Russel East does a blog discussing more in detail Why is MVVM is different from MVC

Here is a solution in plain and simple C++ code with no fancy function, use DMA to allocate a dynamic string array, and put data in array till you find a open space. please refer code below with comments. I hope it helps.
#include<bits/stdc++.h>
using namespace std;
int main()
{
string data="hello there how are you"; // a_size=5, char count =23
//getline(cin,data);
int count=0; // initialize a count to count total number of spaces in string.
int len=data.length();
for (int i = 0; i < (int)data.length(); ++i)
{
if(data[i]==' ')
{
++count;
}
}
//declare a string array +1 greater than the size
// num of space in string.
string* str = new string[count+1];
int i, start=0;
for (int index=0; index<count+1; ++index) // index array to increment index of string array and feed data.
{ string temp="";
for ( i = start; i <len; ++i)
{
if(data[i]!=' ') //increment temp stored word till you find a space.
{
temp=temp+data[i];
}else{
start=i+1; // increment i counter to next to the space
break;
}
}str[index]=temp;
}
//print data
for (int i = 0; i < count+1; ++i)
{
cout<<str[i]<<" ";
}
return 0;
}
I would change the query in the following ways:
group by
.left outer join
to ensure that all data is available.count(<fieldname>)
you can eliminate the comparisons to is null
. This is important for the second and third calculated values.mde
table. These use mde.mdeid
.The following version follows your example by using union all
:
SELECT CAST(Detail.ReceiptDate AS DATE) AS "Date",
SUM(TOTALMAILED) as TotalMailed,
SUM(TOTALUNDELINOTICESRECEIVED) as TOTALUNDELINOTICESRECEIVED,
SUM(TRACEUNDELNOTICESRECEIVED) as TRACEUNDELNOTICESRECEIVED
FROM ((select SentDate AS "ReceiptDate", COUNT(*) as TotalMailed,
NULL as TOTALUNDELINOTICESRECEIVED, NULL as TRACEUNDELNOTICESRECEIVED
from MailDataExtract
where SentDate is not null
group by SentDate
) union all
(select MDE.ReturnMailDate AS ReceiptDate, 0,
COUNT(distinct mde.mdeid) as TOTALUNDELINOTICESRECEIVED,
SUM(case when sd.ReturnMailTypeId = 1 then 1 else 0 end) as TRACEUNDELNOTICESRECEIVED
from MailDataExtract MDE left outer join
DTSharedData.dbo.ScanData SD
ON SD.ScanDataID = MDE.ReturnScanDataID
group by MDE.ReturnMailDate;
)
) detail
GROUP BY CAST(Detail.ReceiptDate AS DATE)
ORDER BY 1;
The following does something similar using full outer join
:
SELECT coalesce(sd.ReceiptDate, mde.ReceiptDate) AS "Date",
sd.TotalMailed, mde.TOTALUNDELINOTICESRECEIVED,
mde.TRACEUNDELNOTICESRECEIVED
FROM (select cast(SentDate as date) AS "ReceiptDate", COUNT(*) as TotalMailed
from MailDataExtract
where SentDate is not null
group by cast(SentDate as date)
) sd full outer join
(select cast(MDE.ReturnMailDate as date) AS ReceiptDate,
COUNT(distinct mde.mdeID) as TOTALUNDELINOTICESRECEIVED,
SUM(case when sd.ReturnMailTypeId = 1 then 1 else 0 end) as TRACEUNDELNOTICESRECEIVED
from MailDataExtract MDE left outer join
DTSharedData.dbo.ScanData SD
ON SD.ScanDataID = MDE.ReturnScanDataID
group by cast(MDE.ReturnMailDate as date)
) mde
on sd.ReceiptDate = mde.ReceiptDate
ORDER BY 1;

Queue is an interface; you can't explicitly construct a Queue. You'll have to instantiate one of its implementing classes. Something like:
Queue linkedList = new LinkedList();
import requests
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
data = requests.get(url).json
maybe?
if you are trying to send a file
files = {'request_file': open('request.json', 'rb')}
r = requests.post(url, files=files)
print r.text, print r.json
ahh thanks @LukasGraf now i better understand what his original code is doing
import requests,json
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
my_json_data = json.load(open("request.json"))
req = requests.post(url,data=my_json_data)
print req.text
print
print req.json # maybe?
i have never done this, but it would be done like this:

This is a very generic question and there is a lot of ways it can be answered.
If you want to use JUnit to create the tests, you need to create your testcase class, then create individual test methods that test specific functionality of your class/module under tests (single testcase classes are usually associated with a single "production" class that is being tested) and inside these methods execute various operations and compare the results with what would be correct. It is especially important to try and cover as many corner cases as possible.
In your specific example, you could for example test the following:
To verify the results, you can use various assertXXX methods from the org.junit.Assert class (for convenience, you can do 'import static org.junit.Assert.*'). These methods test a particular condition and fail the test if it does not validate (with a specific message, optionally).
Example testcase class in your case (without the methods contents defined):
import static org.junit.Assert.*;
public class AdditionTests {
@Test
public void testSimpleAddition() { ... }
@Test
public void testPositiveNegativeAddition() { ... }
@Test
public void testNegativePositiveAddition() { ... }
@Test
public void testNegativeAddition() { ... }
@Test
public void testOverflow() { ... }
}
If you are not used to writing unit tests but instead test your code by writing ad-hoc tests that you then validate "visually" (for example, you write a simple main method that accepts arguments entered using the keyboard and then prints out the results - and then you keep entering values and validating yourself if the results are correct), then you can start by writing such tests in the format above and validating the results with the correct assertXXX method instead of doing it manually. This way, you can re-run the test much easier then if you had to do manual tests.
For enabling readonly:
$("#descrip").attr("readonly","true");
For disabling readonly
$("#descrip").attr("readonly","");
In javascript there are trues and truthys. When something is true it is obviously true or false. When something is truthy it may or may not be a boolean, but the "cast" value of is a boolean.
Examples.
true == true; // (true) true
1 == true; // (true) truthy
"hello" == true; // (true) truthy
[1, 2, 3] == true; // (true) truthy
[] == false; // (true) truthy
false == false; // (true) true
0 == false; // (true) truthy
"" == false; // (true) truthy
undefined == false; // (true) truthy
null == false; // (true) truthy
This can make things simpler if you want to check if a string is set or an array has any values.
var users = [];
if(users) {
// this array is populated. do something with the array
}
var name = "";
if(!name) {
// you forgot to enter your name!
}
And as stated. expect(something).toBe(true)
and expect(something).toBeTrue()
is the same. But expect(something).toBeTruthy()
is not the same as either of those.
we can use \b as a word boundary and then; \b\d+\b

Here is some resource you can read about pseudo-random number generator.

By
std::default_random_engine generator(<some seed number>);

I would use:
awk 'FNR <= 1' file_*.txt
As @Kusalananda points out there are many ways to capture the first line in command line but using the head -n 1
may not be the best option when using wildcards since it will print additional info. Changing 'FNR == i'
to 'FNR <= i'
allows to obtain the first i lines.
For example, if you have n files named file_1.txt, ... file_n.txt:
awk 'FNR <= 1' file_*.txt
hello
...
bye
But with head
wildcards print the name of the file:
head -1 file_*.txt
==> file_1.csv <==
hello
...
==> file_n.csv <==
bye

In my experience, the things I need to make environment-specific are things like connection strings, appsettings and often smpt settings. The config system allows to specify these things in separate files. So you can use this in your app.config/web.config:
<appSettings configSource="appsettings.config" />
<connectionStrings configSource="connection.config" />
<system.net>
<mailSettings>
<smtp configSource="smtp.config"/>
</mailSettings>
</system.net>
What I typically do is to put these config-specific sections in separate files, in a subfolder called ConfigFiles (either in the solution root or at the project level, depends). I define a file per configuration, e.g. smtp.config.Debug and smtp.config.Release.
Then you can define a pre-build event like so:
copy $(ProjectDir)ConfigFiles\smtp.config.$(ConfigurationName) $(TargetDir)smtp.config
In team development, you can tweak this further by including the %COMPUTERNAME% and/or %USERNAME% in the convention.
Of course, this implies that the target files (x.config) should NOT be put in source control (since they are generated). You should still add them to the project file and set their output type property to 'copy always' or 'copy if newer' though.
Simple, extensible, and it works for all types of Visual Studio projects (console, winforms, wpf, web).
Uncaught TypeError: undefined is not a function example_app.js:7
This error message tells the whole story. On this line, you are trying to execute a function. However, whatever is being executed is not a function! Instead, it's undefined
.
So what's on example_app.js
line 7? Looks like this:
var tasks = new ExampleApp.Collections.Tasks(data.tasks);
There is only one function being run on that line. We found the problem! ExampleApp.Collections.Tasks
is undefined
.
So lets look at where that is declared:
var Tasks = Backbone.Collection.extend({
model: Task,
url: '/tasks'
});
If that's all the code for this collection, then the root cause is right here. You assign the constructor to global variable, called Tasks
. But you never add it to the ExampleApp.Collections
object, a place you later expect it to be.
Change that to this, and I bet you'd be good.
ExampleApp.Collections.Tasks = Backbone.Collection.extend({
model: Task,
url: '/tasks'
});
See how important the proper names and line numbers are in figuring this out? Never ever regard errors as binary (it works or it doesn't). Instead read the error, in most cases the error message itself gives you the critical clues you need to trace through to find the real issue.
In Javascript, when you execute a function, it's evaluated like:
expression.that('returns').aFunctionObject(); // js
execute -> expression.that('returns').aFunctionObject // what the JS engine does
That expression can be complex. So when you see undefined is not a function
it means that expression did not return a function object. So you have to figure out why what you are trying to execute isn't a function.
And in this case, it was because you didn't put something where you thought you did.
Thread.sleep can throw an InterruptedException which is a checked exception. All checked exceptions must either be caught and handled or else you must declare that your method can throw it. You need to do this whether or not the exception actually will be thrown. Not declaring a checked exception that your method can throw is a compile error.
You either need to catch it:
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
// handle the exception...
// For example consider calling Thread.currentThread().interrupt(); here.
}
Or declare that your method can throw an InterruptedException
:
public static void main(String[]args) throws InterruptedException

Here is how I scale <img> tags. If you want to make it a background image you can set it's position to absolute, place the image where you want (using the: top, bottom, left, right declarations), and set it's z-index below the rest of your page.
//simple example .your_class_name { width: 100%; height:auto; }
//background image example .your_background_class_name { width: 100%; height:auto; top: 0px; left: 0px; z-index: -1; position: absolute; }
To implement this you would simply place an image tag inside the data-role="page" element of your page(s) that has the ".your_background_class_name" class and the src attribute set to the image you want to have as your background.
I hope this helps.
In PHP 5+ objects are passed by reference. In PHP 4 they are passed by value (that's why it had runtime pass by reference, which became deprecated).
You can use the 'clone' operator in PHP5 to copy objects:
$objectB = clone $objectA;
Also, it's just objects that are passed by reference, not everything as you've said in your question...

For the sake of others having this issue - I landed here because I tried to get cute with how I set up a new github repository, but per the setup page credential helper doesn't work unless you clone a repository.
"Tip: The credential helper only works when you clone an HTTPS repository URL. If you use the SSH repository URL instead, SSH keys are used for authentication. This guide offers help generating and using an SSH key pair."
By default it will be hidden in your home directory. Type ls -a ~

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = db.parse(new ByteArrayInputStream(xmlString.getBytes("UTF-8"))); //remove the parameter UTF-8 if you don't want to specify the Encoding type.
this works well for me even though the XML structure is complex.
And please make sure your xmlString is valid for XML, notice the escape character should be added "\" at the front.
The main problem might not come from the attributes.
If you want to provide a timeout for a particular query, then CommandTimeout is the way forward.

I would like to suggest to use react-native-vector-icons to import icons to your project. As you use vector icons, you don't need to worry much on icon scaling side. While using the package you are able to use all popular icon set such as fontawesome, ionicons etc..
Besides these iconsets you can also bring your own icons too to your react-native project by packing your icons as a ttf file and you can import that ttf directly to both android and ios project. You can utilise the same react-native-vector-icons library to manage those icons
Here is a detailed procedure to setup custom icons

You can use the Google Collections API for that, recently renamed to Guava, specifically a BiMap
A bimap (or "bidirectional map") is a map that preserves the uniqueness of its values as well as that of its keys. This constraint enables bimaps to support an "inverse view", which is another bimap containing the same entries as this bimap but with reversed keys and values.

# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()
t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0
t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))

There is no difference at all!
1) git checkout -b branch origin/branch
If there is no --track
and no --no-track
, --track
is assumed as default. The default can be changed with the setting branch.autosetupmerge
.
In effect, 1) behaves like git checkout -b branch --track origin/branch
.
2) git checkout --track origin/branch
“As a convenience”, --track
without -b
implies -b
and the argument to -b
is guessed to be “branch”. The guessing is driven by the configuration variable remote.origin.fetch
.
In effect, 2) behaves like git checkout -b branch --track origin/branch
.
As you can see: no difference.
But it gets even better:
3) git checkout branch
is also equivalent to git checkout -b branch --track origin/branch
if “branch” does not exist yet but “origin/branch” does1.
All three commands set the “upstream” of “branch” to be “origin/branch” (or they fail).
Upstream is used as reference point of argument-less git status
, git push
, git merge
and thus git pull
(if configured like that (which is the default or almost the default)).
E.g. git status
tells you how far behind or ahead you are of upstream, if one is configured.
git push
is configured to push the current branch upstream by default2 since git 2.0.
1 ...and if “origin” is the only remote having “branch”
2 the default (named “simple”) also enforces for both branch names to be equal
We use a custom provider for multi language support and put all texts in a database table. It works well except we sometimes face caching problems when updating texts in the database without updating the web application.
To my experience on most SQL Servers there is no backup of the transaction log. Full backups or differential backups are common practice, but transaction log backups are really seldom. So the transaction log file grows forever (until the disk is full). In this case the recovery model should be set to "simple". Don't forget to modify the system databases "model" and "tempdb", too.
A backup of the database "tempdb" makes no sense, so the recovery model of this db should always be "simple".
This code (example) :
Chronology ch1 = GregorianChronology.getInstance(); Chronology ch2 = ISOChronology.getInstance(); DateTime dt = new DateTime("2013-12-31T22:59:21+01:00",ch1); DateTime dt2 = new DateTime("2013-12-31T22:59:21+01:00",ch2); System.out.println(dt); System.out.println(dt2); boolean b = dt.equals(dt2); System.out.println(b);
Will print :
2013-12-31T16:59:21.000-05:00 2013-12-31T16:59:21.000-05:00 false
You are probably comparing two DateTimes with same date but different Chronology.
At the risk of getting yelled at, i would get a javascript helper library like jquery or prototype they encapsulate the logic in nice methods - both have an .each method/iterator to do it - and they both strive to make it cross-browser compatible
EDIT: This answer was posted in 2008. Today much better constructs exist. This particular case could be solved with a .forEach
.
Suddenly, without any major change in my project, I too got this error.
All the above did not work for me, since I needed both the support libs V4 and V7.
At the end, because 2 hours ago the project compiled with no problems, I simply told Android Studio to REBUILD the project, and the error was gone.
Just use .animate()
instead of .css()
(with a duration if you want), like this:
$('#hfont1').hover(function() {
$(this).animate({"color":"#efbe5c","font-size":"52pt"}, 1000);
}, function() {
$(this).animate({"color":"#e8a010","font-size":"48pt"}, 1000);
});
You can test it here. Note though, you need either the jQuery color plugin, or jQuery UI included to animate the color. In the above, the duration is 1000ms, you can change it, or just leave it off for the default 400ms duration.

float bside = dot((p - b),(a - b));
if(bside< 0.0) return length(p-b);
vec2 pointOnLine = (bside*a + aside*b)/pow(length(a-b),2.0);
return length(p - pointOnLine);

Similar problem here: Given a string and a list of keywords, detect which, if any, of the keywords are contained in the string.
Recommendations from this thread suggest stringr
's str_detect
and grepl
. Here are the benchmarks from the microbenchmark
package:
Using
map_keywords = c("once", "twice", "few")
t = "yes but only a few times"
mapper1 <- function (x) {
r = str_detect(x, map_keywords)
}
mapper2 <- function (x) {
r = sapply(map_keywords, function (k) grepl(k, x, fixed = T))
}
and then
microbenchmark(mapper1(t), mapper2(t), times = 5000)
we find
Unit: microseconds
expr min lq mean median uq max neval
mapper1(t) 26.401 27.988 31.32951 28.8430 29.5225 2091.476 5000
mapper2(t) 19.289 20.767 24.94484 23.7725 24.6220 1011.837 5000
As you can see, over 5,000 iterations of the keyword search using str_detect
and grepl
over a practical string and vector of keywords, grepl
performs quite a bit better than str_detect
.
The outcome is the boolean vector r
which identifies which, if any, of the keywords are contained in the string.
Therefore, I recommend using grepl
to determine if any keywords are in a string.
Would not \\(.*?\\)
work? That is the non-greedy syntax.
Line break accepts an optional argument in brackets, a vertical length:
line 1
\\[4in]
line 2
To make this more scalable with respect to font size, you can use other lengths, such as \\[3\baselineskip]
, or \\[3ex]
.
I just ran into this myself since I'm trying to create myself a bare bones framework but started out by creating a new Win32 Program option in Visual Studio 2017. "stdafx.h" is unnecessary and should be removed. Then you can remove the stupid "stdafx.h" and "stdafx.cpp" that is in your Solution Explorer as well as the files from your project. In it's place, you'll need to put
#include <Windows.h>
instead.
Detailed explanation for each scope can be found here in Spring bean scopes. Below is the summary
Singleton - (Default) Scopes a single bean definition to a single object instance per Spring IoC container.
prototype - Scopes a single bean definition to any number of object instances.
request - Scopes a single bean definition to the lifecycle of a single HTTP request; that is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext.
session - Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext.
global session - Scopes a single bean definition to the lifecycle of a global HTTP Session. Typically only valid when used in a portlet context. Only valid in the context of a web-aware Spring ApplicationContext.

$pdf->SetY($Y_Fields_Name_position);
$pdf->SetX(#);
$pdf->MultiCell($height,$width,"Line1 \nLine2 \nLine3",1,'C',1);
In every Column, before you set the X Position indicate first the Y position, so it became like this
Column 1
$pdf->SetY($Y_Fields_Name_position);
$pdf->SetX(#);
$pdf->MultiCell($height,$width,"Line1 \nLine2 \nLine3",1,'C',1);
Column 2
$pdf->SetY($Y_Fields_Name_position);
$pdf->SetX(#);
$pdf->MultiCell($height,$width,"Line1 \nLine2 \nLine3",1,'C',1);
There's good answers in here. I'm just adding mine since I ran into the same error but it turned out to be a completely different problem. (Maybe on the surface the same, but a different root cause.)
For me the error happened for the following field:
@Column(nullable = false, columnDefinition = "VARCHAR(255)")
private URI consulUri;
This ends up being stored in the database as a binary serialization of the URI
class. This didn't raise any flags with unit testing (using H2) or CI/integration testing (using MariaDB4j), it blew up in our production-like setup. (Though, once the problem was understood, it was easy enough to see the wrong value in the MariaDB4j instance; it just didn't blow up the test.) The solution was to build a custom type mapper:
package redacted;
import javax.persistence.AttributeConverter;
import java.net.URI;
import java.net.URISyntaxException;
import static java.lang.String.format;
public class UriConverter implements AttributeConverter<URI, String> {
@Override
public String convertToDatabaseColumn(URI attribute) {
return attribute.toString();
}
@Override
public URI convertToEntityAttribute(String field) {
try {
return new URI(field);
}
catch (URISyntaxException e) {
throw new RuntimeException(format("could not convert database field to URI: %s", field));
}
}
}
Used as follows:
@Column(nullable = false, columnDefinition = "VARCHAR(255)")
@Convert(converter = UriConverter.class)
private URI consulUri;
As far as Hibernate is involved, it seems it has a bunch of provided type mappers, including for java.net.URL
, but not for java.net.URI
(which is what we needed here).
you have to open the file in append mode, which can be achieved by using the FileWriter(String fileName, boolean append)
constructor.
output = new BufferedWriter(new FileWriter(my_file_name, true));
should do the trick

Turn off pre compiled headers:
Project Properties -> C++ -> Precompiled Headers
set Precompiled Header
to "Not Using Precompiled Header"

Building on and and enhancing the answer by @piro , you can build a contextmanager. This allows for very readable code which will disable the alaram signal after a successful run (sets signal.alarm(0))
@contextmanager
def timeout(duration):
def timeout_handler(signum, frame):
raise Exception(f'block timedout after {duration} seconds')
signal.signal(signal.SIGALRM, timeout_handler)
signal.alarm(duration)
yield
signal.alarm(0)
def sleeper(duration):
time.sleep(duration)
print('finished')
Example usage:
In [19]: with timeout(2):
...: sleeper(1)
...:
finished
In [20]: with timeout(2):
...: sleeper(3)
...:
---------------------------------------------------------------------------

It seems that you should use the multiprocessing.Pool class instead and use the methods .apply() .apply_async(), map()

As of today, the UI of developer tools in Google chrome has changed where we select the log level of log statements being shown in the console. There is a logging level drop down beside "Filter" text box. Supported values are Verbose
, Info
, Warnings
and Errors
with Info
being the default selection.
Any log whose severity is equal or higher will get shown in the "Console" tab e.g. if selected log level is Info
then all the logs having level Info
, Warning
and Error
will get displayed in console.
When I changed it to Verbose
then my console.debug
and console.log
statements started showing up in the console. Till the time Info
level was selected they were not getting shown.
I typically use function attributes as storage for annotations. Suppose I want to write, in the style of C# (indicating that a certain method should be part of the web service interface)
class Foo(WebService):
@webmethod
def bar(self, arg1, arg2):
...
then I can define
def webmethod(func):
func.is_webmethod = True
return func
Then, when a webservice call arrives, I look up the method, check whether the underlying function has the is_webmethod attribute (the actual value is irrelevant), and refuse the service if the method is absent or not meant to be called over the web.
You can pass the element into the function <input type="button" value="mybutton1" onclick="dosomething(this)">test
by passing this. Then in the function you can access the value like this:
function dosomething(element) {
console.log(element.value);
}
Supposing the form is the direct parent you can do:
<a href='#' onclick='this.parentNode.submit(); return false;'>submit</a>
If not you can access through the forms name attribute like this:
<a href='#' onclick='document.forms["myform"].submit(); return false;'>submit</a>
See both examples here: http://jsfiddle.net/WEZDC/1/
break just breaks the loop & return gets control back to the caller method.
Windows.Forms.Form
, so just a new window Page is, according to online documentation:
Encapsulates a page of content that can be navigated to and hosted by Windows Internet Explorer, NavigationWindow, and Frame.
So you basically use this if going you visualize some HTML content
UserControl is for cases when you want to create some reusable component (but not standalone one) to use it in multiple different Windows
Scala evolved out of a pure functional language known as Funnel and represents a clean-room implementation of almost all Java's syntax, differing only where a clear improvement could be made or where it would compromise the functional nature of the language. Such differences include singleton objects instead of static methods, and type inference.
Much of this was based on Martin Odersky's prior work with the Pizza language. The OO/FP integration goes far beyond mere closures and has led to the language being described as post-functional.
Despite this, it's the closest to Java in many ways. Mainly due to a combination of OO support and static typing, but also due to a explicit goal in the language design that it should integrate very tightly with Java.
Groovy explicitly tackles two of Java's biggest criticisms by
It's perhaps syntactically closest to Java, not offering some of the richer functional constructs that Clojure and Scala provide, but still offering a definite evolutionary improvement - especially for writing script-syle programs.
Groovy has the strongest commercial backing of the three languages, mostly via springsource.
Clojure is a functional language in the LISP family, it's also dynamically typed.
Features such as STM support give it some of the best out-of-the-box concurrency support, whereas Scala requires a 3rd-party library such as Akka to duplicate this.
Syntactically, it's also the furthest of the three languages from typical Java code.
I also have to disclose that I'm most acquainted with Scala :)
As mentioned in the error, the official manual and the comments:
Replace
public function TSStatus($host, $queryPort)
with
public function __construct($host, $queryPort)
The following code (in Kotlin) works from API 21 until at least current API version (API 29). The function getWifiState() returns one of 3 possible values for the WiFi network state: Disable, EnabledNotConnected and Connected that were defined in an enum class. This allows to take more granular decisions like informing the user to enable WiFi or, if already enabled, to connect to one of the available networks. But if all that is needed is a boolean indicating if the WiFi interface is connected to a network, then the other function isWifiConnected() will give you that. It uses the previous one and compares the result to Connected.
It's inspired in some of the previous answers but trying to solve the problems introduced by the evolution of Android API's or the slowly increasing availability of IP V6. The trick was to use:
wifiManager.connectionInfo.bssid != null
instead of:
According to the documentation: https://developer.android.com/reference/kotlin/android/net/wifi/WifiInfo.html#getbssid it will return null if not connected to a network. And even if we do not have permission to get the real value, it will still return something other than null if we are connected.
Also have the following in mind:
On releases before android.os.Build.VERSION_CODES#N, this object should only be obtained from an Context#getApplicationContext(), and not from any other derived context to avoid memory leaks within the calling process.
In the Manifest, do not forget to add:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
Proposed code is:
class MyViewModel(application: Application) : AndroidViewModel(application) {
// Get application context
private val myAppContext: Context = getApplication<Application>().applicationContext
// Define the different possible states for the WiFi Connection
internal enum class WifiState {
Disabled, // WiFi is not enabled
EnabledNotConnected, // WiFi is enabled but we are not connected to any WiFi network
Connected, // Connected to a WiFi network
}
// Get the current state of the WiFi network
private fun getWifiState() : WifiState {
val wifiManager : WifiManager = myAppContext.applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager
return if (wifiManager.isWifiEnabled) {
if (wifiManager.connectionInfo.bssid != null)
WifiState.Connected
else
WifiState.EnabledNotConnected
} else {
WifiState.Disabled
}
}
// Returns true if we are connected to a WiFi network
private fun isWiFiConnected() : Boolean {
return (getWifiState() == WifiState.Connected)
}
}
There is a timeout on broken connections (i.e. due to network errors), which relies on the OS' TCP keepalive feature. By default on Linux, broken TCP connections are closed after ~2 hours (see sysctl net.ipv4.tcp_keepalive_time
).
There is also a timeout on abandoned transactions, idle_in_transaction_session_timeout
and on locks, lock_timeout
. It is recommended to set these in postgresql.conf
.
But there is no timeout for a properly established client connection. If a client wants to keep the connection open, then it should be able to do so indefinitely. If a client is leaking connections (like opening more and more connections and never closing), then fix the client. Do not try to abort properly established idle connections on the server side.
I've tried all of these above but none worked when you needed to match without accepting duplicates.
For example:
var a1 = [1, 2, 1, 4], a2 = [1, 2, 4];
Would return an empty diff array because 2
would be found once in the second array, even though we need it to match twice.
So I've managed to fix something up:
Array.prototype.diff = function(a) {
return this.filter(function(item) {
match = a.indexOf(item);
if (match)
a.splice(match, 1);
return match < 0;
});
};
You could do this pretty easily with my date-shortcode package:
const dateShortcode = require('date-shortcode')
var startDate = 'Monday, January 9, 2010'
dateShortcode.parse('{M/D/YYYY}', startDate)
//=> '1/9/2010'

You can use GNU date, for example,
$ sec=1267619929
$ date -d "UTC 1970-01-01 $sec secs"
or
$ date -ud @1267619929
You can also split a string at every n-th character and put them each, in each index of a List :
Here I made a list of Strings named Sequence :
List < String > Sequence
Then I'm basically splitting the String "KILOSO" by every 2 words. So 'KI' 'LO' 'SO' would be incorporate in separate index of the List called Sequence.
String S = KILOSO
Sequence = Arrays.asList(S.split("(?<=\G..)"));
So when I'm doing :
System.out.print(Sequence)
It should print :
[KI, LO, SO]
to verify I can write :
System.out.print(Sequence.get(1))
it will print :
LO
This should work:
ax1.plot(xtr, color='r', label='HHZ 1')
ax1.legend(loc="upper right")
ax2.plot(xtr, color='r', label='HHN')
ax2.legend(loc="upper right")
ax3.plot(xtr, color='r', label='HHE')
ax3.legend(loc="upper right")
===
and !==
are strict comparison operators:
JavaScript has both strict and type-converting equality comparison. For
strict
equality the objects being compared must have the same type and:
- Two strings are strictly equal when they have the same sequence of characters, same length, and same characters in corresponding positions.
- Two numbers are strictly equal when they are numerically equal (have the same number value).
NaN
is not equal to anything, includingNaN
. Positive and negative zeros are equal to one another.- Two Boolean operands are strictly equal if both are true or both are false.
- Two objects are strictly equal if they refer to the same
Object
.Null
andUndefined
types are==
(but not===
). [I.e. (Null==Undefined
) istrue
but (Null===Undefined
) isfalse

One option would be to create a symbolic link between a subfolder in your storage directory and public directory.
For example
ln -s /path/to/laravel/storage/avatars /path/to/laravel/public/avatars
This is also the method used by Envoyer, a deployment manager built by Taylor Otwell, the developer of Laravel.
Make sure your email address variable is not blank. Check using
print_r($variable_passed);
edit: I guess it's now starting to be safe to use the native JSON.stringify() method, supported by most browsers (yes, even IE8+ if you're wondering).
As simple as:
JSON.stringify(yourData)
You should encode you data in JSON before sending it, you can't just send an object like this as POST data.
I recommand using the jQuery json plugin to do so. You can then use something like this in jQuery:
$.post(_saveDeviceUrl, {
data : $.toJSON(postData)
}, function(response){
//Process your response here
}
);
What you're basically doing here is relying on Date#toString()
which already has a fixed pattern. To convert a Java Date
object into another human readable String pattern, you need SimpleDateFormat#format()
.
private String modifyDateLayout(String inputDate) throws ParseException{
Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss z").parse(inputDate);
return new SimpleDateFormat("dd.MM.yyyy HH:mm:ss").format(date);
}
By the way, the "unparseable date" exception can here only be thrown by SimpleDateFormat#parse()
. This means that the inputDate
isn't in the expected pattern "yyyy-MM-dd HH:mm:ss z"
. You'll probably need to modify the pattern to match the inputDate
's actual pattern.
Update: Okay, I did a test:
public static void main(String[] args) throws Exception {
String inputDate = "2010-01-04 01:32:27 UTC";
String newDate = new Test().modifyDateLayout(inputDate);
System.out.println(newDate);
}
This correctly prints:
03.01.2010 21:32:27
(I'm on GMT-4)
Update 2: as per your edit, you really got a ParseException
on that. The most suspicious part would then be the timezone of UTC
. Is this actually known at your Java environment? What Java version and what OS version are you using? Check TimeZone.getAvailableIDs()
. There must be a UTC
in between.
You can create a variable with an application scope
I had the same problem as you and ended up making a jQuery plugin to take care of it. It actually solves all the problems people have listed here, plus it adds a couple of optional features too.
stickyPanelSettings = {
// Use this to set the top margin of the detached panel.
topPadding: 0,
// This class is applied when the panel detaches.
afterDetachCSSClass: "",
// When set to true the space where the panel was is kept open.
savePanelSpace: false,
// Event fires when panel is detached
// function(detachedPanel, panelSpacer){....}
onDetached: null,
// Event fires when panel is reattached
// function(detachedPanel){....}
onReAttached: null,
// Set this using any valid jquery selector to
// set the parent of the sticky panel.
// If set to null then the window object will be used.
parentSelector: null
};
There is a better way that is safer and will not slow down your application. How Excel is set up, a cell can have either a value or a formula; the formula can not refer to its own cell. Otherwise, You end up with an infinite loop, since the new value would cause another calculation... .
Use a helper column to calculate the value based on what you put in the other cell.
For Example:
Column A is a True or False, Column B contains a monetary value, Column C contains the following formula:
=B1
Now, to calculate that column B will be highlighted yellow in a conditional format only if Column A is True and Column B is greater than Zero...
=AND(A1=True,C1>0)
You can then choose to hide column C
Traverse through the array and find the index of the element which contains a key name
and has the value as the passed param.

It is probably better to create a dedicated function to create the link so you can avoid creating two anonymous functions. Thus:
<div id="div"></div>
<script>
function getLink(id)
{
var link = document.createElement('a');
link.setAttribute('href', '#');
link.innerHTML = id;
link.onclick = function()
{
onClickLink(id);
};
link.style.display = 'block';
return link;
}
var div = document.getElementById('div');
for (var i = 0; i < 10; i += 1)
{
div.appendChild(getLink(i.toString()));
}
</script>
Although in both cases you end up with two functions, I just think it is better to wrap it in a function that is semantically easier to comprehend.
For People, looking for answers w.r.t to 'map' function and dynamic data, here is a working example.
<img src={"http://examole.com/randomview/images" + each_actor['logo']} />
This gives the URL as "http://examole.com/randomview/images/2/dp_pics/182328.jpg" (random example)

there is a cross browser script for get parent origin:

const locationAreDisctint = (window.location !== window.parent.location);
const parentOrigin = ((locationAreDisctint ? document.referrer : document.location) || "").toString();
if (parentOrigin) {
return new URL(parentOrigin).origin;
}
const currentLocation = document.location;
if (currentLocation.ancestorOrigins && currentLocation.ancestorOrigins.length) {
return currentLocation.ancestorOrigins[0];
}
return "";
}
This code, should work on Chrome and Firefox.

Have the.htaccess file in the application root directory, along with the index.php file. (Check if the htaccess extension is correct , Bz htaccess.txt did not work for me.)
And Add the following rules to .htaccess file,
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
Then find the following line in your application/config/config.php file
$config['index_page'] = 'index.php';
Set the variable empty as below.
$config['index_page'] = '';
That's it, it worked for me.
If it doesn't work further try to replace following variable with these parameters ('AUTO', 'PATH_INFO', 'QUERY_STRING', 'REQUEST_URI', and 'ORIG_PATH_INFO') one by one
$config['uri_protocol'] = 'AUTO';
Use the following script tag in your jsp/js file:
<script src="http://code.jquery.com/jquery-1.9.0.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.js"></script>
this will work for sure.
If you have a QMainWindow
you can override closeEvent
method.
#include <QCloseEvent>
void MainWindow::closeEvent (QCloseEvent *event)
{
QMessageBox::StandardButton resBtn = QMessageBox::question( this, APP_NAME,
tr("Are you sure?\n"),
QMessageBox::Cancel | QMessageBox::No | QMessageBox::Yes,
QMessageBox::Yes);
if (resBtn != QMessageBox::Yes) {
event->ignore();
} else {
event->accept();
}
}
If you're subclassing a QDialog
, the closeEvent
will not be called and so you have to override reject()
:
void MyDialog::reject()
{
QMessageBox::StandardButton resBtn = QMessageBox::Yes;
if (changes) {
resBtn = QMessageBox::question( this, APP_NAME,
tr("Are you sure?\n"),
QMessageBox::Cancel | QMessageBox::No | QMessageBox::Yes,
QMessageBox::Yes);
}
if (resBtn == QMessageBox::Yes) {
QDialog::reject();
}
}
Use
table{border-collapse:collapse}
tr{border-top:thin solid}
Replace "thin solid" with CSS properties.
Instead of the *
selector you can use the :not(selector)
with the >
selector and set something that definitely wont be a child.
Edit: I thought it would be faster but it turns out I was wrong. Disregard.
Example:
.container > :not(marquee){
color:red;
}
<div class="container">
<p></p>
<span></span>
<div>
If you want to go even further than @tetra with ES6 you can use the Object spread syntax and do something like this:
let john = {
firstName: "John",
lastName: "Doe",
};
let people = new Array(10).fill().map((e, i) => {(...john, id: i});
It looks like you're using ngModel on the same form field as formControlName. Support for using the ngModel input property and ngModelChange event with reactive form directives has been deprecated in Angular v6 and will be removed in Angular v7
You need to ensure that auto-commit on the Connection is turned off, or setFetchSize will have no effect.
dbConnection.setAutoCommit(false);
Edit: Remembered that when I used this fix it was Postgres-specific, but hopefully it will still work for SQL Server.
I just published a command line interface utility to npm and github that allows you to copy keys that match a given pattern (even *) from one Redis database to another.
You can find the utility here:
public void Method()
{
if(something)
{
//some code
if(something2)
{
// The code i want to go if the second if is true
}
return;
}
}
ser.read(64)
should be ser.read(size=64)
; ser.read uses keyword arguments, not positional.
Also, you're reading from the port twice; what you probably want to do is this:
i=0
for modem in PortList:
for port in modem:
try:
ser = serial.Serial(port, 9600, timeout=1)
ser.close()
ser.open()
ser.write("ati")
time.sleep(3)
read_val = ser.read(size=64)
print read_val
if read_val is not '':
print port
except serial.SerialException:
continue
i+=1
Simply replace it with nothing:
var string = 'F0123456'; // just an example
string.replace(/^F0+/i, ''); '123456'
I had many issues involving C# and SqlServer. I ended up doing the following:
Also make sure that all your machines run on the same timezone.
Regarding the different result sets you get, your first example is "July First" while the second is "4th of July" ...
Also, the second example can be also interpreted as "April 7th", it depends on your server localization configuration (my solution doesn't suffer from this issue).
EDIT: hh was replaced with HH, as it doesn't seem to capture the correct hour on systems with AM/PM as opposed to systems with 24h clock. See the comments below.

Use:
<?php
$str = "...server daemon started with pid=6849 (parent=6848).";
$from = "pid=";
$to = "(";
echo getStringBetween($str,$from,$to);
function getStringBetween($str,$from,$to)
{
$sub = substr($str, strpos($str,$from)+strlen($from),strlen($str));
return substr($sub,0,strpos($sub,$to));
}
?>
Another way to do it is using the StructField if you have multiple fields that needs to be modified.
Ex:
from pyspark.sql.types import StructField,IntegerType, StructType,StringType
newDF=[StructField('CLICK_FLG',IntegerType(),True),
StructField('OPEN_FLG',IntegerType(),True),
StructField('I1_GNDR_CODE',StringType(),True),
StructField('TRW_INCOME_CD_V4',StringType(),True),
StructField('ASIAN_CD',IntegerType(),True),
StructField('I1_INDIV_HHLD_STATUS_CODE',IntegerType(),True)
]
finalStruct=StructType(fields=newDF)
df=spark.read.csv('ctor.csv',schema=finalStruct)
Output:
Before
root
|-- CLICK_FLG: string (nullable = true)
|-- OPEN_FLG: string (nullable = true)
|-- I1_GNDR_CODE: string (nullable = true)
|-- TRW_INCOME_CD_V4: string (nullable = true)
|-- ASIAN_CD: integer (nullable = true)
|-- I1_INDIV_HHLD_STATUS_CODE: string (nullable = true)
After:
root
|-- CLICK_FLG: integer (nullable = true)
|-- OPEN_FLG: integer (nullable = true)
|-- I1_GNDR_CODE: string (nullable = true)
|-- TRW_INCOME_CD_V4: string (nullable = true)
|-- ASIAN_CD: integer (nullable = true)
|-- I1_INDIV_HHLD_STATUS_CODE: integer (nullable = true)
This is slightly a long procedure to cast , but the advantage is that all the required fields can be done.
It is to be noted that if only the required fields are assigned the data type, then the resultant dataframe will contain only those fields which are changed.
Monolithic kernel is a single large process running entirely in a single address space. It is a single static binary file. All kernel services exist and execute in the kernel address space. The kernel can invoke functions directly. Examples of monolithic kernel based OSs: Unix, Linux.
In microkernels, the kernel is broken down into separate processes, known as servers. Some of the servers run in kernel space and some run in user-space. All servers are kept separate and run in different address spaces. Servers invoke "services" from each other by sending messages via IPC (Interprocess Communication). This separation has the advantage that if one server fails, other servers can still work efficiently. Examples of microkernel based OSs: Mac OS X and Windows NT.
Yes you can create a nested data structure people
which can be indexed by Anna
and Ben
. However, you can't index it directly by age
and profession
(I will get to this part in the code).
The data type of people
is of type Json::Value
(which is defined in jsoncpp). You are right, it is similar to the nested map, but Value
is a data structure which is defined such that multiple types can be stored and accessed. It is similar to a map with a string
as the key and Json::Value
as the value. It could also be a map between an unsigned int
as key and Json::Value
as the value (In case of json arrays).
Here's the code:
#include <json/value.h>
#include <fstream>
std::ifstream people_file("people.json", std::ifstream::binary);
people_file >> people;
cout<<people; //This will print the entire json object.
//The following lines will let you access the indexed objects.
cout<<people["Anna"]; //Prints the value for "Anna"
cout<<people["ben"]; //Prints the value for "Ben"
cout<<people["Anna"]["profession"]; //Prints the value corresponding to "profession" in the json for "Anna"
cout<<people["profession"]; //NULL! There is no element with key "profession". Hence a new empty element will be created.
As you can see, you can index the json object only based on the hierarchy of the input data.
Unrelated to mockito, one can catch the exception and assert its properties. To verify that the exception did happen, assert a false condition within the try block after the statement that throws the exception.
Experience With: ASUS ZENFONE
If at all you have faced Missing Driver for Asus Zenfones Follow This Link (http://donandroid.com/how-to-install-adb-interface-drivers-windows-7-xp-vista-623)
I tried with
1) Killing and starting adb server at adb cmd.
2) Switching Usb Debugging on and Off and ...
This is What WORKED with me.
Step 1:Remove Connection with Device and Close Eclipse
Step 2:Navigate to C:/Users/User_name/.android/
Step 3:You Will Find adb_key
Step 4:Just delete it.
Step 5.Connect again and System will ask you Again.
Step 6.Ask Device to remember RSA Key when it Prompts. I think its done.
If you Face The Same Problem after couple of days, just disable and enable USB debugging
Just some minor modification to your code will do (with some var renaming for clarity) :
double sum = 0; //average will have decimal point
for(int i=0; i < args.length; i++){
//parse string to double, note that this might fail if you encounter a non-numeric string
//Note that we could also do Integer.valueOf( args[i] ) but this is more flexible
sum += Double.valueOf( args[i] );
}
double average = sum/args.length;
System.out.println(average );
Note that the loop can also be simplified:
for(String arg : args){
sum += Double.valueOf( arg );
}
Edit: the OP seems to want to use the args
array. This seems to be a String array, thus updated the answer accordingly.
Update:
As zoxqoj correctly pointed out, integer/double overflow is not taken care of in the code above. Although I assume the input values will be small enough to not have that problem, here's a snippet to use for really large input values:
BigDecimal sum = BigDecimal.ZERO;
for(String arg : args){
sum = sum.add( new BigDecimal( arg ) );
}
This approach has several advantages (despite being somewhat slower, so don't use it for time critical operations):
BigDecimal
might be bigger than what fits into a double
or long
.i tought it's because the connection but i use this:
git push --force origin master
Pass float to sleep, like sleep 0.1
You can create constants in many different ways:
const myString = "hello"
const pi = 3.14 // untyped constant
const life int = 42 // typed constant (can use only with ints)
You can also create a enum constant:
const (
First = 1
Second = 2
Third = 4
)
You can not create constants of maps, arrays and it is written in effective go:
Constants in Go are just that—constant. They are created at compile time, even when defined as locals in functions, and can only be numbers, characters (runes), strings or booleans. Because of the compile-time restriction, the expressions that define them must be constant expressions, evaluatable by the compiler. For instance, 1<<3 is a constant expression, while math.Sin(math.Pi/4) is not because the function call to math.Sin needs to happen at run time.
Please ensure that your mongo DB is set Automatic and running at Control Panel/Administrative Tools/Services like below. That way you wont have to start mongod.exe manually each time.
open cmd
type in netstat -a -n -o
find TCP [the IP address]:[port number] .... #[target_PID]#
(ditto for UDP)
(Btw, kill [target_PID]
didn't work for me)
CTRL+ALT+DELETE and choose "start task manager"
Click on "Processes" tab
Enable "PID" column by going to: View > Select Columns > Check the box for PID
Find the PID of interest and "END PROCESS"
Now you can rerun the server on [the IP address]:[port number] without a problem

Yes, you can use what's known as :nth-child
selectors.
In this case you would use:
li:nth-child(3n) {
// Styling for every third element here.
}
:nth-child(3n):
3(0) = 0
3(1) = 3
3(2) = 6
3(3) = 9
3(4) = 12
:nth-child()
is compatible in Chrome, Firefox, and IE9+.
For a work around to use :nth-child()
amongst other pseudo-classes/attribute selectors in IE6 through to IE8, see this link.
I adapted a bit the code of everyone, made it in a Function, made it faster (array), and added parameters :
Public Function FirstBlankCell(Optional Sh As Worksheet, Optional SourceCol As Long = 1, Optional ByVal StartRow& = 1, Optional ByVal SelectCell As Boolean = False) As Long
Dim RowCount As Long, CurrentRow As Long
Dim CurrentRowValue As String
Dim Data()
If Sh Is Nothing Then Set Sh = ActiveSheet
With Sh
rowCount = .Cells(.Rows.Count, SourceCol).End(xlUp).Row
Data = .Range(.Cells(1, SourceCol), .Cells(rowCount, SourceCol)).Value2
For currentRow = StartRow To RowCount
If Data(currentRow, SourceCol) = vbNullString Then
If SelectCell Then .Cells(currentRow, SourceCol).Select
'if selection is out of screen, intead of .select , use : application.goto reference:=.cells(...), scroll:= true
FirstBlankCell = currentRow
Exit For
End If
Next
End With ' Sh
Erase Data
Set Sh = Nothing
End Function
If it's inside a closure, i'm pretty sure you can't.
Otherwise you just do functionName();
and hit return.
An interface consists of singleton variables (public static final) and public abstract methods. We normally prefer to use an interface in real time when we know what to do but don't know how to do it.
This concept can be better understood by example:
Consider a Payment class. Payment can be made in many ways, such as PayPal, credit card etc. So we normally take Payment as our interface which contains a makePayment()
method and CreditCard and PayPal are the two implementation classes.
public interface Payment
{
void makePayment();//by default it is a abstract method
}
public class PayPal implements Payment
{
public void makePayment()
{
//some logic for PayPal payment
//e.g. Paypal uses username and password for payment
}
}
public class CreditCard implements Payment
{
public void makePayment()
{
//some logic for CreditCard payment
//e.g. CreditCard uses card number, date of expiry etc...
}
}
In the above example CreditCard and PayPal are two implementation classes /strategies. An Interface also allows us the concept of multiple inheritance in Java which cannot be accomplished by an abstract class.
We choose an abstract class when there are some features for which we know what to do, and other features that we know how to perform.
Consider the following example:
public abstract class Burger
{
public void packing()
{
//some logic for packing a burger
}
public abstract void price(); //price is different for different categories of burgers
}
public class VegBerger extends Burger
{
public void price()
{
//set price for a veg burger.
}
}
public class NonVegBerger extends Burger
{
public void price()
{
//set price for a non-veg burger.
}
}
If we add methods (concrete/abstract) in the future to a given abstract class, then the implementation class will not need a change its code. However, if we add methods in an interface in the future, we must add implementations to all classes that implemented that interface, otherwise compile time errors occur.
There are other differences but these are major ones which may have been what your interviewer expected . Hopefully this was helpful.
how about using the CSS :first-child pseudo-class:
.MyClass td:first-child { border: solid 1px red; }
First of all make sure that following dependencies are proper added and compiled in build.gradle file
dependencies {
...
compile 'com.android.support:cardview-v7:21.0.+'
}
and after this try the following code :

xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_margin="5dp"
android:orientation="horizontal"
card_view:cardCornerRadius="5dp">
</android.support.v7.widget.CardView
problem rises in Android L beacuse layout_margin attribute is not added
I know this is an old question but here's how I look at it (I find very useful):
Technical explanations
In Java, all variables are either primitive types or references.
(If you need to know what a reference is: "Object variables" are just pointers to objects. So with Object something = ...
, something is really an address in memory (a number).)
==
compares the exact values. So it compares if the primitive values are the same, or if the references (addresses) are the same. That's why ==
often doesn't work on Strings; Strings are objects, and doing ==
on two string variables just compares if the address is same in memory, as others have pointed out. .equals()
calls the comparison method of objects, which will compare the actual objects pointed by the references. In the case of Strings, it compares each character to see if they're equal.
The interesting part:
So why does ==
sometimes return true for Strings? Note that Strings are immutable. In your code, if you do
String foo = "hi";
String bar = "hi";
Since strings are immutable (when you call .trim()
or something, it produces a new string, not modifying the original object pointed to in memory), you don't really need two different String("hi")
objects. If the compiler is smart, the bytecode will read to only generate one String("hi")
object. So if you do
if (foo == bar) ...
right after, they're pointing to the same object, and will return true. But you rarely intend this. Instead, you're asking for user input, which is creating new strings at different parts of memory, etc. etc.
Note: If you do something like baz = new String(bar)
the compiler may still figure out they're the same thing. But the main point is when the compiler sees literal strings, it can easily optimize same strings.
I don't know how it works in runtime, but I assume the JVM doesn't keep a list of "live strings" and check if a same string exists. (eg if you read a line of input twice, and the user enters the same input twice, it won't check if the second input string is the same as the first, and point them to the same memory). It'd save a bit of heap memory, but it's so negligible the overhead isn't worth it. Again, the point is it's easy for the compiler to optimize literal strings.
There you have it... a gritty explanation for ==
vs. .equals()
and why it seems random.
If you want to get unix timestamp, then you need to use:
timestamp=$(date +%s)
%T
will give you just the time; same as %H:%M:%S
(via http://www.cyberciti.biz/faq/linux-unix-formatting-dates-for-display/)
There is a property of the built-in window.location
object that will provide that for the current window.
// If URL is http://www.somedomain.com/account/search?filter=a#top
window.location.pathname // /account/search
// For reference:
window.location.host // www.somedomain.com (includes port if there is one)
window.location.hostname // www.somedomain.com
window.location.hash // #top
window.location.href // http://www.somedomain.com/account/search?filter=a#top
window.location.port // (empty string)
window.location.protocol // http:
window.location.search // ?filter=a
It turns out that this schema is being standardized as an interface called URLUtils, and guess what? Both the existing window.location
object and anchor elements implement the interface.
So you can use the same properties above for any URL — just create an anchor with the URL and access the properties:
var el = document.createElement('a');
el.href = "http://www.somedomain.com/account/search?filter=a#top";
el.host // www.somedomain.com (includes port if there is one[1])
el.hostname // www.somedomain.com
el.hash // #top
el.href // http://www.somedomain.com/account/search?filter=a#top
el.pathname // /account/search
el.port // (port if there is one[1])
el.protocol // http:
el.search // ?filter=a
[1]: Browser support for the properties that include port is not consistent, See: http://jessepollak.me/chrome-was-wrong-ie-was-right
This works in the latest versions of Chrome and Firefox. I do not have versions of Internet Explorer to test, so please test yourself with the JSFiddle example.
There's also a coming URL
object that will offer this support for URLs themselves, without the anchor element. Looks like no stable browsers support it at this time, but it is said to be coming in Firefox 26. When you think you might have support for it, try it out here.
Yes, I think the library you are using is not compatible with 64 bit version but you can solve the problem -
Just navigate to Build Settings>Architectures & replace $(ARCHS_STANDARD)
to $(ARCHS_STANDARD_32_BIT)
So that your xcode build your project with 32 bit supported version.
Python's ability to provide default values for function arguments gives us a way out.
def fce(x=myX, y=myY):
myFunction(x,y)
button = Tk.Button(mainWin, text='press', command=fce)
See: http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/extra-args.html
For more buttons you can create a function which returns a function:
def fce(myX, myY):
def wrapper(x=myX, y=myY):
pass
pass
pass
return x+y
return wrapper
button1 = Tk.Button(mainWin, text='press 1', command=fce(1,2))
button2 = Tk.Button(mainWin, text='press 2', command=fce(3,4))
button3 = Tk.Button(mainWin, text='press 3', command=fce(9,8))
A couple things
(a) you cant have both background-color and background, background will always win. in the example below, i combined them through shorthand, but this will produce the color only as a fallback method when the image does not show.
(b) no-scroll does not work, i don't believe it is a valid property of a background-image. try something like fixed:
.button:after {
content: "";
width: 30px;
height: 30px;
background:red url("http://www.gentleface.com/i/free_toolbar_icons_16x16_black.png") no-repeat -30px -50px fixed;
top: 10px;
right: 5px;
position: absolute;
display: inline-block;
}
I updated your jsFiddle to this and it showed the image.
/* Important part */
.modal-dialog{
overflow-y: initial !important
}
.modal-body{
max-height: calc(100vh - 200px);
overflow-y: auto;
}
This works for Bootstrap 3 without JS code and is responsive.
For big objects you may use a somewhat crude but effective method: check how much memory your Python process occupies in the system, then delete the object and compare.
This method has many drawbacks but it will give you a very fast estimate for very big objects.
In case you'd happen to be using rails and the angular-rails gem then the problem is easily corrected by adding this missing line to application.js (or what ever is applicable in your situation):
//= require angular-resource
It means that you compiled your classes under a specific JDK, but then try to run them under older version of JDK.
