@Gajus Kuizinas and @CodeHater are correct. Here i am just giving an example. While we are working with ng-if, if the assigned value is false then the whole html elements will be removed from DOM. and if assigned value is true, then the html elements will be visible on the DOM. And the scope will be different compared to the parent scope. But in case of ng-show, it wil just show and hide the elements based on the assigned value. But it always stays in the DOM. Only the visibility changes as per the assigned value.
http://plnkr.co/edit/3G0V9ivUzzc8kpLb1OQn?p=preview
Hope this example will help you in understanding the scopes. Try giving false values to ng-show and ng-if and check the DOM in console. Try entering the values in the input boxes and observe the difference.
<!DOCTYPE html>
<input type="text" ng-model="data">
<div ng-show="true">
<br/>ng-show=true :: <br/><input type="text" ng-model="data">
</div>
<div ng-if="true">
<br/>ng-if=true :: <br/><input type="text" ng-model="data">
</div>
{{data}}
sed -i.bak 's/\(aaa=\).*/\1"xxx"/g' your_file
#div-name
{
background-image: url('../images/background-art-main.jpg');
background-position: top right 50px;
background-repeat: no-repeat;
}
There is a rails plugin called Annotate models, that will generate your model attributes on the top of your model files here is the link:
https://github.com/ctran/annotate_models
to keep the annotation in sync, you can write a task to re-generate annotate models after each deploy.
This class will cover your needs, you can pass the variable into ConvertUnixToDatetime & call which function you want it to operate based off.
from datetime import datetime
import time
class ConvertUnixToDatetime:
def __init__(self, date):
self.date = date
# Convert unix to date object
def convert_unix(self):
unix = self.date
# Check if unix is a string or int & proceeds with correct conversion
if type(unix).__name__ == 'str':
unix = int(unix[0:10])
else:
unix = int(str(unix)[0:10])
date = datetime.utcfromtimestamp(unix).strftime('%Y-%m-%d %H:%M:%S')
return date
# Convert date to unix object
def convert_date(self):
date = self.date
# Check if datetime object or raise ValueError
if type(date).__name__ == 'datetime':
unixtime = int(time.mktime(date.timetuple()))
else:
raise ValueError('You are trying to pass a None Datetime object')
return type(unixtime).__name__, unixtime
if __name__ == '__main__':
# Test Date
date_test = ConvertUnixToDatetime(datetime.today())
date_test = date_test.convert_date()
print(date_test)
# Test Unix
unix_test = ConvertUnixToDatetime(date_test[1])
print(unix_test.convert_unix())
Note that in general, IDE's like Visual Studio will markup a comment in the context of the current language, by selecting the text you wish to turn into a comment, and then using the Ctrl+K Ctrl+C shortcut, or if you are using Resharper / Intelli-J style shortcuts, then Ctrl+/.
Server side Comments:
Razor .cshtml
@* Comment goes here *@
.aspx
For those looking for the older .aspx
view (and Asp.Net WebForms) server side comment syntax:
<%-- Comment goes here --%>
Client Side Comments
HTML Comment
<!-- Comment goes here -->
Javascript Comment
// One line Comment goes Here
/* Multiline comment
goes here */
As OP mentions, although not displayed on the browser, client side comments will still be generated for the page / script file on the server and downloaded by the page over HTTP, which unless removed (e.g. minification), will waste I/O, and, since the comment can be viewed by the user by viewing the page source or intercepting the traffic with the browser's Dev Tools or a tool like Fiddler or Wireshark, can also pose a security risk, hence the preference to use server side comments on server generated code (like MVC views or .aspx pages).
if files are not moving this could be due to several reasons
> find * -type d -print0 | xargs -0 chmod 0755 # for directories find * > -type f -print0 | xargs -0 chmod 0666 # for files
chown -R admin:admin public_html # will restore permission to admin for folder and files within it chown admin:admin public_html # will restore permission to admin for folder only will skip files

function instead of move_uploaded_file
You can also use CURRENT_TIMESTAMP
, if you feel like being more ANSI compliant (though if you're porting code between database vendors, that'll be the least of your worries). It's exactly the same as GetDate()
under the covers (see this question for more on that).
There's no ANSI equivalent for GetUTCDate()
, however, which is probably the one you should be using if your app operates in more than a single time zone ...
aView.frame = CGRectMake(100, 200, aView.frame.size.width, aView.frame.size.height);
The concept of http location and disk location is different. What you need to do is:
summer.jpg
c:\images\summer.jpg
summer.jpg
<img src="images/summer.jpg" />
c:\images\
under your application's /images
. If you cannot do this then in step #2 you need to save somewhere under your web root, e.g c:\my-applications\demo-app\build\images
I had the same problem but it didn't work for Python 3. I followed this and it solved my problem:
enc = sys.getdefaultencoding()
file = open(menu, "r", encoding = enc)
You have to set the encoding when you are reading/writing the file.
go to http://dev.mysql.com/downloads/connector/c/ and download MySQL Connector/C. after getting the package, make a new directory 'mysql', uncompress the Mysql Connector file under directory mysql, then under mysql, make another empty directory 'build'.we will use 'build' to build MySQL Connector/C. cd build && cmake ../your-MySQL-Connector-source-dir make && make install after make install, you will get a directory named mysql under /usr/local. it contains all the headers and libs you need.go to this dirctory, and copy the headers and libs to corresponding locations.
The heap is the place in memory where your dynamically allocated objects live. If you used new
then it's on the heap. That's as opposed to stack space, which is where the function stack lives. If you have a local variable then that reference is on the stack.
Java's heap is subject to garbage collection and the objects are usable directly.
EHCache's off-heap storage takes your regular object off the heap, serializes it, and stores it as bytes in a chunk of memory that EHCache manages. It's like storing it to disk but it's still in RAM. The objects are not directly usable in this state, they have to be deserialized first. Also not subject to garbage collection.
$ch = curl_init();
$data = array(

);
$data = http_build_query($data);

This is how you do it, I have checked it and it works on my Laravel 4.2.
$table->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP'));
Hope this helps.
If you're hoping to use background-image: url(...);
, I don't think you can. However, if you want to play with layering, you can do something like this:
<img class="bg" src="..." />
And then some CSS:
.bg
{
width: 100%;
z-index: 0;
}
You can now layer content above the stretched image by playing with z-indexes and such. One quick note, the image can't be contained in any other elements for the width: 100%;
to apply to the whole page.
Here's a quick demo if you can't rely on background-size
: http://jsfiddle.net/bB3Uc/
You can try this:
td p {word-break:break-all;}
This, however, makes it appear like this when there's enough space, unless you add a <br>
tag:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
So, I would then suggest adding <br>
tags where there are newlines, if possible.
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
Also, if this doesn't solve your problem, there's a similar thread here.
If you want to use 1 image and display it in different size, you can use scale drawable ( http://developer.android.com/guide/topics/resources/drawable-resource.html#Scale ).
Always good idea is to make parent class, with functions ... i.e. add this all functionality to parent.
And "move" all classes that use this hierarchically down. I need - rewrite functions, which are specific.
From the Package Explorer in Eclipse, you can right click the project, choose Build Path, Configure Build Path to get the build path dialog. From there you can remove the JRE reference for the 1.5 JRE and 'Add Library' to add a reference to your installed JRE.
Still an issue.
Using parameters like "..css?something=random-value" changes nothing in my customer-support experience. Only name changes works.
Another take on the file renaming. I use URL Rewrite in IIS. Sometimes Helicon's Isapi Rewrite.
Add new rule.
+ Name: lame-chrome-fix.
+ Pattern: styles/(\w+)_(\d+)
+ Rewrite URL: /{R:1}.css
Note: I reserve the use of undercase to separate the name from the random number. Could be anything else.
Example:
<link href="/styles/template_<%
Response.Write( System.DateTime.UtcNow.ToString("ddmmyyhhmmss")); %>"
type="text/css" />
(No styles folder it's just a name part of the pattern)
Output code as:
<link href="/styles/template_285316115328"
rel="stylesheet" type="text/css">
Redirect as:
(R:1 = template)
/template.css
Only the explanation is long.
I found this solution:
This query select last not null value for each column.
Example
If you have a table:
id|title|body
1 |t1 |b1
2 |NULL |b2
3 |t3 |NULL
you get:
title|body
t3 |b2
Query
SELECT DISTINCT (
SELECT title
FROM test
WHERE title IS NOT NULL
ORDER BY id DESC
LIMIT 1
) title, (
SELECT body
FROM test
WHERE body IS NOT NULL
ORDER BY id DESC
LIMIT 1
) body
FROM test
I hope help you.
A common idiom to change every element of a list looks like this:
for i in range(len(L)):
item = L[i]
# ... compute some result based on item ...
L[i] = result
This can be rewritten using enumerate() as:
for i, item in enumerate(L):
# ... compute some result based on item ...
L[i] = result
See enumerate.
The accepted answer has some gotchas. For example:
>>> a = [{}] * 3
>>> a
[{}, {}, {}]
>>> a[0]['hello'] = 5
>>> a
[{'hello': 5}, {'hello': 5}, {'hello': 5}]
>>>
So each dictionary refers to the same object. Same holds true if you initialize with arrays or objects.
You could do this instead:
>>> b = [{} for i in range(0, 3)]
>>> b
[{}, {}, {}]
>>> b[0]['hello'] = 6
>>> b
[{'hello': 6}, {}, {}]
>>>
This will not problem if we use IE browser. This is for other browsers, save file on another location and use that path.

Using the Java 8 Streams approach...
//Creates and sorts a stream (does not sort the original list)
persons.stream().sorted(Comparator.comparing(Person::getName).thenComparing(Person::getAge));
And the Java 8 Lambda approach...
//Sorts the original list Lambda style
persons.sort((p1, p2) -> {
if (p1.getName().compareTo(p2.getName()) == 0) {
return p1.getAge().compareTo(p2.getAge());
} else {
return p1.getName().compareTo(p2.getName());
}
});
Lastly...
//This is similar SYNTAX to the Streams above, but it sorts the original list!!
persons.sort(Comparator.comparing(Person::getName).thenComparing(Person::getAge));
In that version of Android, when a view is inflated, the focus will be set to the first focusable control by default - and if there's no physical keyboard, the on-screen keyboard will pop up.
To fix this, explicitly set focus somewhere else. If focus is set to anything other than an EditText, the on-screen keyboard will not appear.
Have you tried testing this by running Android 1.5 in the emulator?
Make a virtual enviroment using python3
virtualenv env_name --python="python3"
and run the following command
pip3 install opencv-python
Firstly, you probably want to add a return false; to the bottom of your Submit() method in JavaScript (so it stops the submit, since you're handling it in AJAX).
You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:
$.ajax({
type: "POST",
url: "Default.aspx/OnSubmit",
data: dataValue,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
},
success: function (result) {
alert("We returned: " + result);
}
});
Step 1: Build a checked/unchecked selector:
selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/yellow" android:state_checked="true" />
<item android:color="@color/white" android:state_checked="false" />
</selector>
Step 2: use the xml attribute app:itemTextColor
within NavigationView
widget for selecting the text color.
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/navigation_header_layout"
app:itemTextColor="@drawable/selector"
app:menu="@menu/navigation_menu" />
Step 3:
For some reason when you hit an item from the NavigationView
menu, it doesn't consider this as a button check. So you need to manually get the selected item checked and clear the previously selected item. Use below listener to do that
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
int id = item.getItemId();
// remove all colors of the items to the `unchecked` state of the selector
removeColor(mNavigationView);
// check the selected item to change its color set by the `checked` state of the selector
item.setChecked(true);
switch (item.getItemId()) {
case R.id.dashboard:
...
}
drawerLayout.closeDrawer(GravityCompat.START);
return true;
}
private void removeColor(NavigationView view) {
for (int i = 0; i < view.getMenu().size(); i++) {
MenuItem item = view.getMenu().getItem(i);
item.setChecked(false);
}
}
Step 4:
To change icon color, use the app:iconTint
attribute in the NavigationView
menu items, and set to the same selector.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/nav_account"
android:checked="true"
android:icon="@drawable/ic_person_black_24dp"
android:title="My Account"
app:iconTint="@drawable/selector" />
<item
android:id="@+id/nav_settings"
android:icon="@drawable/ic_settings_black_24dp"
android:title="Settings"
app:iconTint="@drawable/selector" />
<item
android:id="@+id/nav_logout"
android:icon="@drawable/logout"
android:title="Log Out"
app:iconTint="@drawable/selector" />
</menu>
Result:
In here you can save the phone number as international formatted phone number
internationalFormatPhoneNumber = phoneUtil.format(givenPhoneNumber, PhoneNumberFormat.INTERNATIONAL);
it return the phone number as International format +94 71 560 4888
so now I have get country code as this
String countryCode = internationalFormatPhoneNumber.substring(0,internationalFormatPhoneNumber.indexOf('')).replace('+', ' ').trim();
Hope this will help you
There is and it is not dependent on post build events.
Add the file to your project, then in the file properties select under "Copy to Output Directory" either "Copy Always" or "Copy if Newer".
See MSDN.
Be careful with the Concat
method. The post Array Concatenation in C# explains that:
var z = x.Concat(y).ToArray();
Will be inefficient for large arrays. That means the Concat
method is only for meduim-sized arrays (up to 10000 elements).
You can also hook XMLHttpRequest send prototype. This will work for all sends (jQuery/dojo/etc) with one handler.
I wrote this code to handle a 500 page expired error, but it should work just as well to trap a 200 redirect. Ready the wikipedia entry on XMLHttpRequest onreadystatechange about the meaning of readyState.
// Hook XMLHttpRequest
var oldXMLHttpRequestSend = XMLHttpRequest.prototype.send;
XMLHttpRequest.prototype.send = function() {
//console.dir( this );
this.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 500 && this.responseText.indexOf("Expired") != -1) {
try {
document.documentElement.innerHTML = this.responseText;
} catch(error) {
// IE makes document.documentElement read only
document.body.innerHTML = this.responseText;
}
}
};
oldXMLHttpRequestSend.apply(this, arguments);
}

This is just another way of doing it:
private String capitalize(String line)
{
StringTokenizer token =new StringTokenizer(line);
String CapLine="";
while(token.hasMoreTokens())
{
String tok = token.nextToken().toString();
CapLine += Character.toUpperCase(tok.charAt(0))+ tok.substring(1)+" ";
}
return CapLine.substring(0,CapLine.length()-1);
}
There's nothing built into java to do this. But, hey, java is a programming language, so.. let's program it!
map.entrySet().stream().map(e -> e.getKey() + "=" + e.getValue()).collect(Collectors.joining("&"))
This gives you "param1=12¶m2=cat". Now we need to join the URL and this bit together. You'd think you can just do: URL + "?" + theAbove
but if the URL already contains a question mark, you have to join it all together with "&" instead. One way to check is to see if there's a question mark in the URL someplace already.
Also, I don't quite know what is in your map. If it's raw stuff, you probably have to safeguard the call to e.getKey()
and e.getValue()
with URLEncoder.encode
or similar.
Yet another way to go is that you take a wider view. Are you trying to append a map's content to a URL, or... are you trying to make an HTTP(S) request from a java process with the stuff in the map as (additional) HTTP params? In the latter case, you can look into an http library like OkHttp which has some nice APIs to do this job, then you can forego any need to mess about with that URL in the first place.
This will do the job:
<div style="position:absolute; right:0;">Hello world</div>
_x000D_
You need to make the call using $.ajax()
to it synchronously, like this:
$.ajax({
url: myUrl,
dataType: 'json',
async: false,
data: myData,
success: function(data) {
//stuff
//...
}
});
This would match currently using $.getJSON()
like this:
$.getJSON(myUrl, myData, function(data) {
//stuff
//...
});
New and neat in Python 3.5:
[*map(chr, [66, 53, 0, 94])]
Thanks to Additional Unpacking Generalizations
UPDATE
Always seeking for shorter ways, I discovered this one also works:
*map(chr, [66, 53, 0, 94]),
Unpacking works in tuples too. Note the comma at the end. This makes it a tuple of 1 element. That is, it's equivalent to (*map(chr, [66, 53, 0, 94]),)
It's shorter by only one char from the version with the list-brackets, but, in my opinion, better to write, because you start right ahead with the asterisk - the expansion syntax, so I feel it's softer on the mind. :)
Click event of textbox? Or even MouseCaptureChanged event works for me. - OK. doesn't work.
So you have to do 2 things:
private bool f = false;
private void textBox_MouseClick(object sender, MouseEventArgs e)
{
if (this.f) { this.textBox.SelectAll(); }
this.f = false;
}
private void textBox_Enter(object sender, EventArgs e)
{
this.f = true;
this.textBox.SelectAll();
}
private void textBox_MouseMove(object sender, MouseEventArgs e) // idea from the other answer
{
this.f = false;
}
Works for tabbing (through textBoxes to the one) as well - call SelectAll() in Enter just in case...
Negatives are your friend here:
SELECT Col1
FROM TABLE
WHERE Col1 like '%[^a-Z0-9]%'
Which says that you want any rows where Col1
consists of any number of characters, then one character not in the set a-Z0-9, and then any number of characters.
If you have a case sensitive collation, it's important that you use a range that includes both upper and lower case A
, a
, Z
and z
, which is what I've given (originally I had it the wrong way around. a
comes before A
. Z
comes after z
)
Or, to put it another way, you could have written your original WHERE
as:
Col1 LIKE '[!@#$%]'
But, as you observed, you'd need to know all of the characters to include in the []
.
By setting activity theme in Manifest,
<activity

From memset()
:
memset(myarray, 0, sizeof(myarray));
You can use sizeof(myarray)
if the size of myarray
is known at compile-time. Otherwise, if you are using a dynamically-sized array, such as obtained via malloc
or new
, you will need to keep track of the length.
I think, you could also do something like...
setTimeout(function(){
$(".message-class").trigger("click");
}, 5000);
and do your animated effects on the event-click...
$(".message-class").click(function() {
//your event-code
});
Greetings,
If you are getting this error, it could be because you don't have a route defined for your get.
For example:
const express = require('express');
const app = express();
app.get('/people', function (req, res) {
res.send('hello');
})
app.listen(3000);
http://http://localhost:3000/people --> this works
http://http://localhost:3000 --> this will output Cannot GET / message.
What is the best approach to do this JAVA?
I would personally NOT use Axis 2, even for client side development only. Here is why I stay away from it:
The only reason Axis is still around is IMO because it's used in Eclipse since ages. Thanks god, this has been fixed in Eclipse Helios and I hope Axis2 will finally die. There are just much better stacks.
I read about SAAJ, looks like that will be more granular level of approach?
To do what?
Is there any other way than using the WSDL2Java tool, to generate the code. Maybe wsimport in another option. What are the pros and cons?
Yes! Prefer a JAX-WS stack like CXF or JAX-WS RI (you might also read about Metro, Metro = JAX-WS RI + WSIT), they are just more elegant, simpler, easier to use. In your case, I would just use JAX-WS RI which is included in Java 6 and thus wsimport
.
Can someone send the links for some good tutorials on these topics?
That's another pro, there are plenty of (good quality) tutorials for JAX-WS, see for example:
What are the options we need to use while generating the code using the WSDL2Java?
No options, use wsimport
:)
1.If I have something like Foo o = new Foo(); inside the method, does that mean that each time the timer ticks, I'm creating a new object and a new reference to that object?
Yes.
2.If I have string foo = null and then I just put something temporal in foo, is it the same as above?
If you are asking if the behavior is the same then yes.
3.Does the garbage collector ever delete the object and the reference or objects are continually created and stay in memory?
The memory used by those objects is most certainly collected after the references are deemed to be unused.
4.If I just declare Foo o; and not point it to any instance, isn't that disposed when the method ends?
No, since no object was created then there is no object to collect (dispose is not the right word).
5.If I want to ensure that everything is deleted, what is the best way of doing it
If the object's class implements IDisposable
then you certainly want to greedily call Dispose
as soon as possible. The using
keyword makes this easier because it calls Dispose
automatically in an exception-safe way.
Other than that there really is nothing else you need to do except to stop using the object. If the reference is a local variable then when it goes out of scope it will be eligible for collection.1 If it is a class level variable then you may need to assign null
to it to make it eligible before the containing class is eligible.
1This is technically incorrect (or at least a little misleading). An object can be eligible for collection long before it goes out of scope. The CLR is optimized to collect memory when it detects that a reference is no longer used. In extreme cases the CLR can collect an object even while one of its methods is still executing!
Update:
Here is an example that demonstrates that the GC will collect objects even though they may still be in-scope. You have to compile a Release build and run this outside of the debugger.
static void Main(string[] args)
{
Console.WriteLine("Before allocation");
var bo = new BigObject();
Console.WriteLine("After allocation");
bo.SomeMethod();
Console.ReadLine();
// The object is technically in-scope here which means it must still be rooted.
}
private class BigObject
{
private byte[] LotsOfMemory = new byte[Int32.MaxValue / 4];
public BigObject()
{
Console.WriteLine("BigObject()");
}
~BigObject()
{
Console.WriteLine("~BigObject()");
}
public void SomeMethod()
{
Console.WriteLine("Begin SomeMethod");
GC.Collect();
GC.WaitForPendingFinalizers();
Console.WriteLine("End SomeMethod");
}
}
On my machine the finalizer is run while SomeMethod
is still executing!
To select the right location provider for your app, you can use Criteria objects:
Criteria myCriteria = new Criteria();
myCriteria.setAccuracy(Criteria.ACCURACY_HIGH);
myCriteria.setPowerRequirement(Criteria.POWER_LOW);
// let Android select the right location provider for you
String myProvider = locationManager.getBestProvider(myCriteria, true);
// finally require updates at -at least- the desired rate
long minTimeMillis = 600000; // 600,000 milliseconds make 10 minutes
locationManager.requestLocationUpdates(myProvider,minTimeMillis,0,locationListener);
Read the documentation for requestLocationUpdates for more details on how the arguments are taken into account:
The frequency of notification may be controlled using the minTime and minDistance parameters. If minTime is greater than 0, the LocationManager could potentially rest for minTime milliseconds between location updates to conserve power. If minDistance is greater than 0, a location will only be broadcasted if the device moves by minDistance meters. To obtain notifications as frequently as possible, set both parameters to 0.
Criteria.ACCURACY_HIGH
criterion should give you errors below 100m, which is not as good as GPS can be, but matches your needs.the best way i found was to set the image you want to view responsively as a background image and sent a css property for the div as cover.

You can also simply set your pandas column as list of id values with length same as of dataframe.
df['New_ID'] = range(880, 880+len(df))

That depends on what the target server accepts. There is no definitive standard for this. See also a.o. Wikipedia: Query string:
While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field (e.g.
field1=value1&field1=value2&field2=value3
).[4][5]
Generally, when the target server uses a strong typed programming language like Java (Servlet), then you can just send them as multiple parameters with the same name. The API usually offers a dedicated method to obtain multiple parameter values as an array.
foo=value1&foo=value2&foo=value3
String[] foo = request.getParameterValues("foo"); // [value1, value2, value3]
The request.getParameter("foo")
will also work on it, but it'll return only the first value.
String foo = request.getParameter("foo"); // value1
And, when the target server uses a weak typed language like PHP or RoR, then you need to suffix the parameter name with braces []
in order to trigger the language to return an array of values instead of a single value.
foo[]=value1&foo[]=value2&foo[]=value3
$foo = $_GET["foo"]; // [value1, value2, value3]
echo is_array($foo); // true
In case you still use foo=value1&foo=value2&foo=value3
, then it'll return only the first value.
$foo = $_GET["foo"]; // value1
echo is_array($foo); // false
Do note that when you send foo[]=value1&foo[]=value2&foo[]=value3
to a Java Servlet, then you can still obtain them, but you'd need to use the exact parameter name including the braces.
String[] foo = request.getParameterValues("foo[]"); // [value1, value2, value3]
<xsl:text disable-output-escaping="yes">& </xsl:text>
will do the trick.
Here's how i'd do it:
FN=someletters_12345_moreleters.ext
[[ ${FN} =~ _([[:digit:]]{5})_ ]] && NUM=${BASH_REMATCH[1]}
Explanation:
Bash-specific:
[[ ]]
indicates a conditional expression=~
indicates the condition is a regular expression&&
chains the commands if the prior command was successfulRegular Expressions (RE): _([[:digit:]]{5})_
_
are literals to demarcate/anchor matching boundaries for the string being matched()
create a capture group[[:digit:]]
is a character class, i think it speaks for itself{5}
means exactly five of the prior character, class (as in this example), or group must matchIn english, you can think of it behaving like this: the FN
string is iterated character by character until we see an _
at which point the capture group is opened and we attempt to match five digits. If that matching is successful to this point, the capture group saves the five digits traversed. If the next character is an _
, the condition is successful, the capture group is made available in BASH_REMATCH
, and the next NUM=
statement can execute. If any part of the matching fails, saved details are disposed of and character by character processing continues after the _
. e.g. if FN
where _1 _12 _123 _1234 _12345_
, there would be four false starts before it found a match.

A different approach using concat and drop_duplicates:
import sys
if sys.version_info[0] < 3:
from StringIO import StringIO
else:
from io import StringIO
import pandas as pd
DF1 = StringIO("""id Name score isEnrolled Comment
111 Jack 2.17 True "He was late to class"
112 Nick 1.11 False "Graduated"
113 Zoe NaN True " "
""")
DF2 = StringIO("""id Name score isEnrolled Comment
111 Jack 2.17 True "He was late to class"
112 Nick 1.21 False "Graduated"
113 Zoe NaN False "On vacation" """)
df1 = pd.read_table(DF1, sep='\s+', index_col='id')
df2 = pd.read_table(DF2, sep='\s+', index_col='id')
#%%
dictionary = {1:df1,2:df2}
df=pd.concat(dictionary)
df.drop_duplicates(keep=False)
Output:
Name score isEnrolled Comment
id
1 112 Nick 1.11 False Graduated
113 Zoe NaN True
2 112 Nick 1.21 False Graduated
113 Zoe NaN False On vacation
System.getProperties()
can be overridden by calls to System.setProperty(String key, String value)
or with command line parameters -Dfile.separator=/
File.separator
gets the separator for the default filesystem.
FileSystems.getDefault()
gets you the default filesystem.
FileSystem.getSeparator()
gets you the separator character for the filesystem. Note that as an instance method you can use this to pass different filesystems to your code other than the default, in cases where you need your code to operate on multiple filesystems in the one JVM.
I create a file dif.go
that contains your code:
package dif
import (
"time"
)
var StartTime = time.Now()
Outside the folder I create my main.go
, it is ok!
package main
import (
dif "./dif"
"fmt"
)
func main() {
fmt.Println(dif.StartTime)
}
Outputs:
2016-01-27 21:56:47.729019925 +0800 CST
Files directory structure:
folder
main.go
dif
dif.go
It works!
The /i switch might be what your after.
From xcopy /?
/I If destination does not exist and copying more than one file, assumes that destination must be a directory.
Here's a working solution that creates admin-user
user with a password, additional database (test-database
), and test-user
in that database.
Dockerfile:
FROM mongo:4.0.3
ENV MONGO_INITDB_ROOT_USERNAME admin-user
ENV MONGO_INITDB_ROOT_PASSWORD admin-password
ENV MONGO_INITDB_DATABASE admin
ADD mongo-init.js /docker-entrypoint-initdb.d/
mongo-init.js:
db.auth('admin-user', 'admin-password')
db = db.getSiblingDB('test-database')
db.createUser({
user: 'test-user',
pwd: 'test-password',
roles: [
{
role: 'root',
db: 'test-database',
},
],
});
The tricky part was to understand that *.js files were run unauthenticated.
The solution authenticates the script as the admin-user
in the admin
database. MONGO_INITDB_DATABASE admin
is essential, otherwise the script would be executed against the test
db. Check the source code of docker-entrypoint.sh.
Try this:
<li onclick="myfunction(this)">
function myfunction(li) {
var TextInsideLi = li.getElementsByTagName('p')[0].innerHTML;
}
This was my solution to protect against an empty array as well:
import React, { Component } from 'react';
import { arrayOf, shape, string, number } from 'prop-types';
ReactComponent.propTypes = {
arrayWithShape: (props, propName, componentName) => {
const arrayWithShape = props[propName]
PropTypes.checkPropTypes({ arrayWithShape:
arrayOf(
shape({
color: string.isRequired,
fontSize: number.isRequired,
}).isRequired
).isRequired
}, {arrayWithShape}, 'prop', componentName);
if(arrayWithShape.length < 1){
return new Error(`${propName} is empty`)
}
}
}
Its very simple actually. Try this:
str1="a b c d"
splitStr1 = str1.split()
print splitStr1
All of these answers miss one important point -- the n'th line is the n'th line in the file, and not the n'th row in the dataset. I have a situation where I download some antiquated stream gauge data from the USGS. The head of the dataset is commented with '#', the first line after that are the labels, next comes a line that describes the date types, and last the data itself. I never know how many comment lines there are, but I know what the first couple of rows are. Example:
----------------------------- WARNING ----------------------------------
Some of the data that you have obtained from this U.S. Geological Survey database
may not have received Director's approval. ... agency_cd site_no datetime tz_cd 139719_00065 139719_00065_cd
5s 15s 20d 6s 14n 10s USGS 08041780 2018-05-06 00:00 CDT 1.98 A
It would be nice if there was a way to automatically skip the n'th row as well as the n'th line.
As a note, I was able to fix my issue with:
import pandas as pd
ds = pd.read_csv(fname, comment='#', sep='\t', header=0, parse_dates=True)
ds.drop(0, inplace=True)
First store the table in a view, then select columns from that view into a new table.
// Create a table with abitrary columns for use with the example
System.Data.DataTable table = new System.Data.DataTable();
for (int i = 1; i <= 11; i++)
table.Columns.Add("col" + i.ToString());
// Load the table with contrived data
for (int i = 0; i < 100; i++)
{
System.Data.DataRow row = table.NewRow();
for (int j = 0; j < 11; j++)
row[j] = i.ToString() + ", " + j.ToString();
table.Rows.Add(row);
}
// Create the DataView of the DataTable
System.Data.DataView view = new System.Data.DataView(table);
// Create a new DataTable from the DataView with just the columns desired - and in the order desired
System.Data.DataTable selected = view.ToTable("Selected", false, "col1", "col2", "col6", "col7", "col3");
Used the sample data to test this method I found: Create ADO.NET DataView showing only selected Columns
We just had to work around this problem and tested three different approaches.

In our case we decided to use approach #3 as it produces less load for the server. But I am not 100% sure if jQuery guarantees the call of the .complete()-method, this could produce a deadlock situation. In our tests we could not reproduce such a situation.
A simple solution to solve this issue both in vs developer command prompt and cmd is to add the following line
C:\Windows\System32
into the system path as follows:
My Pc-->properties-->Advanced-->Environment variables-->system variables hope it solves the issue.
Try the :lt selector: http://docs.jquery.com/Selectors/lt#index
$('a:lt(20)');
Example code using NLog that will catch exceptions thrown from all threads in the AppDomain, from the UI dispatcher thread and from the async functions:
public partial class App : Application

{
base.OnStartup(e);
SetupExceptionHandling();
}
private void SetupExceptionHandling()
{

LogUnhandledException((Exception)e.ExceptionObject, "AppDomain.CurrentDomain.UnhandledException");

e.Handled = true;
};
TaskScheduler.UnobservedTaskException += (s, e) =>
{
LogUnhandledException(e.Exception, "TaskScheduler.UnobservedTaskException");
e.SetObserved();
};
}
private void LogUnhandledException(Exception exception, string source)
{
string message = $"Unhandled exception ({source})";
try

pkill
with script path
pkill -9 -f path/to/my_script.py
is a short and selective method that is more likely to only kill the interpreter running a given script.

For a healthy increase of performance using node to serve static resources, I recommend using Buffet. It works similar to as a web application accelerator also known as a caching HTTP reverse proxy but it just loads the chosen directory into memory.
Buffet takes a fully-bufferred approach -- all files are fully loaded into memory when your app boots, so you will never feel the burn of the filesystem. In practice, this is immensely efficient. So much so that putting Varnish in front of your app might even make it slower!
We use it on the codePile site and found an increase of ~700requests/sec to >4k requests/sec on a page that downloads 25 resources under a 1k concurrent user connection load.
Example:
var server = require('http').createServer();
var buffet = require('buffet')(root: './file');
server.on('request', function (req, res) {
buffet(req, res, function () {
buffet.notFound(req, res);
});
});
server.listen(3000, function () {
console.log('test server running on port 3000');
});
How does spring know which polymorphic type to use.
As long as there is only a single implementation of the interface and that implementation is annotated with @Component
with Spring's component scan enabled, Spring framework can find out the (interface, implementation) pair. If component scan is not enabled, then you have to define the bean explicitly in your application-config.xml (or equivalent spring configuration file).
Do I need @Qualifier or @Resource?
Once you have more than one implementation, then you need to qualify each of them and during auto-wiring, you would need to use the @Qualifier
annotation to inject the right implementation, along with @Autowired
annotation. If you are using @Resource (J2EE semantics), then you should specify the bean name using the name
attribute of this annotation.
Why do we autowire the interface and not the implemented class?
Firstly, it is always a good practice to code to interfaces in general. Secondly, in case of spring, you can inject any implementation at runtime. A typical use case is to inject mock implementation during testing stage.
interface IA
{
public void someFunction();
}
class B implements IA
{
public void someFunction()
{
//busy code block
}
public void someBfunc()
{
//doing b things
}
}
class C implements IA
{
public void someFunction()
{
//busy code block
}
public void someCfunc()
{
//doing C things
}
}
class MyRunner
{
@Autowire
@Qualifier("b")
IA worker;
....
worker.someFunction();
}
Your bean configuration should look like this:
<bean id="b" class="B" />
<bean id="c" class="C" />
<bean id="runner" class="MyRunner" />
Alternatively, if you enabled component scan on the package where these are present, then you should qualify each class with @Component
as follows:
interface IA
{
public void someFunction();
}
@Component(value="b")
class B implements IA
{
public void someFunction()
{
//busy code block
}
public void someBfunc()
{
//doing b things
}
}
@Component(value="c")
class C implements IA
{
public void someFunction()
{
//busy code block
}
public void someCfunc()
{
//doing C things
}
}
@Component
class MyRunner
{
@Autowire
@Qualifier("b")
IA worker;
....
worker.someFunction();
}
Then worker
in MyRunner
will be injected with an instance of type B
.
If you mean what ports are listening, you can open a command prompt and write:
netstat
You can write:
netstat /?
for an explanation of all options.
You can use:
width: -webkit-fit-content;
height: -webkit-fit-content;
width: -moz-fit-content;
height: -moz-fit-content;
EDIT: No. see http://red-team-design.com/horizontal-centering-using-css-fit-content-value/

If your request is sent by HTTPS you will have an extra server variable named 'HTTPS'
if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') { //HTTPS }
Response.Redirect()
will send you to a new page, update the address bar and add it to the Browser History. On your browser you can click back.
Server.Transfer()
does not change the address bar. You cannot hit back.
I use Server.Transfer()
when I don't want the user to see where I am going. Sometimes on a "loading" type page.
Otherwise I'll always use Response.Redirect()
.
It seems to me that simply: ls -lt mydirectory
does the job...
I ran into this error while I was using Microsoft Visual Studio Code's integrated git terminal. For some weird reason VS code was not allowing me to install 'node-sass'. Then I used 'Git Bash' (which was installed with git) and ran the following command:
npm install node-sass
It worked for me. I don't know why & how it worked. If anyone has any explanation please let me know.
Each row has an ID. All you have to do is to send this ID to the function setSelected()
, store it (in $scope.idSelectedVote
for instance), and then check for each row if the selected ID is the same as the current one. Here is a solution (see the documentation for ngClass
, if needed):
$scope.idSelectedVote = null;
$scope.setSelected = function (idSelectedVote) {
$scope.idSelectedVote = idSelectedVote;
};
<ul ng-repeat="vote in votes" ng-click="setSelected(vote.id)" ng-class="{selected: vote.id === idSelectedVote}">
...
</ul>
Here is your solution for the problem,
$letter = array();
for ($i = 'A'; $i !== 'ZZ'; $i++){
if(ord($i) % 2 != 0)
$letter[] .= $i;
}
print_r($letter);
You need to get the ASCII value for that character which will solve your problem.
Here is ord doc and working code.
For your requirement, you can do like this,
for ($i = 'A'; $i !== 'ZZ'; ord($i)+$x){
$letter[] .= $i;
}
print_r($letter);
Here set $x as per your requirement.
jQuery.scrollTo will do everything you want and more!

that means this zk server can not connect to other servers, and i found this server ping other servers fail, and after remove this server from the replica, the problem is solved.
hope this will be helpful.
If you are familiar with gcc, as you indicated in the question, you can install MinGW, which will set a linux-like compile environment in Win7. Otherwise, Visual Studio 2010 Express is the best choice.
Basically, this will not work out
Format("20130423014854","yyyy-MM-dd hh:mm:ss")
the format
function will only work if your string has correct format

In order to make
http://localhost:8080
work, tomcat has to be started first. You can check server.xml file in conf folder for the port information. You can search if tomcat is installed on your machine. Just go to start and then type tomcat. If it is installed it will give you the directory where it is installed. Then you can select that path and run it from command prompt. Example if tomcat is installed in C:\Programfile\tomcat. You need to set this path in command prompt,go to bin folder and startup. Example: C:\Programfile\tomcat\bin\startup. Else you can also run it by directly going to the path and run startup batch file.

Cloning elements in an array is not something that can be done in a universal way. Do you want deep cloning or a simple copy of all members?
Let's go for the "best effort" approach: cloning objects using the ICloneable interface or binary serialization:
public static class ArrayExtensions
{
public static T[] SubArray<T>(this T[] array, int index, int length)
{
T[] result = new T[length];
for (int i=index;i<length+index && i<array.Length;i++)
{
if (array[i] is ICloneable)
result[i-index] = (T) ((ICloneable)array[i]).Clone();
else
result[i-index] = (T) CloneObject(array[i]);
}
return result;
}
private static object CloneObject(object obj)
{
BinaryFormatter formatter = new BinaryFormatter();
using (MemoryStream stream = new MemoryStream())
{
formatter.Serialize(stream, obj);
stream.Seek(0,SeekOrigin.Begin);
return formatter.Deserialize(stream);
}
}
}
This is not a perfect solution, because there simply is none that will work for any type of object.
Below is a good solution in Java though!
NumberFormat fmt = NumberFormat.getCurrencyInstance();
System.out.println(fmt.format(n));
or for a more robust way you may want to get the locale of a particular place, then use as below:
int n=9999999;
Locale locale = new Locale("en", "US");
NumberFormat fmt = NumberFormat.getCurrencyInstance(locale);
System.out.println(fmt.format(n));
US Locale OUTPUT: $9,999,999.00
German Locale output
Locale locale = new Locale("de", "DE");
OUTPUT: 9.999.999,00 €
Indian Locale output
Locale locale = new Locale("de", "DE");
OUTPUT: Rs.9,999,999.00
Estonian Locale output
Locale locale = new Locale("et", "EE");
OUTPUT: 9 999 999 €
As you can see in different outputs you don't have to worry about the separator being a comma or dot or even space you can get the number formatted according to the i18n standards
A lot of other answers are focusing on a pattern that does work, but their explanations aren't really very thorough as to why your current code doesn't work.
Your code, for reference:
function funcName() {
alert("test");
}
var func = funcName();
var run = setInterval("func",10000)
Let's break this up into chunks. Your function funcName
is fine. Note that when you call funcName
(in other words, you run it) you will be alerting "test"
. But notice that funcName()
-- the parentheses mean to "call" or "run" the function -- doesn't actually return a value. When a function doesn't have a return value, it defaults to a value known as undefined
.
When you call a function, you append its argument list to the end in parentheses. When you don't have any arguments to pass the function, you just add empty parentheses, like funcName()
. But when you want to refer to the function itself, and not call it, you don't need the parentheses because the parentheses indicate to run it.
So, when you say:
var func = funcName();
You are actually declaring a variable func
that has a value of funcName()
. But notice the parentheses. funcName()
is actually the return value of funcName
. As I said above, since funcName
doesn't actually return any value, it defaults to undefined
. So, in other words, your variable func
actually will have the value undefined
.
Then you have this line:
var run = setInterval("func",10000)
The function setInterval
takes two arguments. The first is the function to be ran every so often, and the second is the number of milliseconds between each time the function is ran.
However, the first argument really should be a function, not a string. If it is a string, then the JavaScript engine will use eval
on that string instead. So, in other words, your setInterval is running the following JavaScript code:
func
// 10 seconds later....
func
// and so on
However, func
is just a variable (with the value undefined
, but that's sort of irrelevant). So every ten seconds, the JS engine evaluates the variable func
and returns undefined
. But this doesn't really do anything. I mean, it technically is being evaluated every 10 seconds, but you're not going to see any effects from that.
The solution is to give setInterval
a function to run instead of a string. So, in this case:
var run = setInterval(funcName, 10000);
Notice that I didn't give it func
. This is because func
is not a function in your code; it's the value undefined
, because you assigned it funcName()
. Like I said above, funcName()
will call the function funcName
and return the return value of the function. Since funcName
doesn't return anything, this defaults to undefined
. I know I've said that several times now, but it really is a very important concept: when you see funcName()
, you should think "the return value of funcName
". When you want to refer to a function itself, like a separate entity, you should leave off the parentheses so you don't call it: funcName
.
So, another solution for your code would be:
var func = funcName;
var run = setInterval(func, 10000);
However, that's a bit redundant: why use func
instead of funcName
?
Or you can stay as true as possible to the original code by modifying two bits:
var func = funcName;
var run = setInterval("func()", 10000);
In this case, the JS engine will evaluate func()
every ten seconds. In other words, it will alert "test"
every ten seconds. However, as the famous phrase goes, eval
is evil, so you should try to avoid it whenever possible.
Another twist on this code is to use an anonymous function. In other words, a function that doesn't have a name -- you just drop it in the code because you don't care what it's called.
setInterval(function () {
alert("test");
}, 10000);
In this case, since I don't care what the function is called, I just leave a generic, unnamed (anonymous) function there.
To get the output of ls
, use stdout=subprocess.PIPE
.
>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo
The command cdrecord --help
outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True
argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.
>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
-version print version information and exit
dev=target SCSI target to use as CD/DVD-Recorder
gracetime=# set the grace time before starting to write to #.
...
If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.
subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
As mentioned by Chris Morgan, you should be using proc.communicate()
instead of proc.read()
.
>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout:
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
-version print version information and exit
dev=target SCSI target to use as CD/DVD-Recorder
gracetime=# set the grace time before starting to write to #.

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.
Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$
How you can use regular expressions depends on the version of iOS you are using.
You can use NSRegularExpression
, which allows you to compile and test against a regular expression directly.
Does not include the NSRegularExpression
class, but does include NSPredicate
, which can match against regular expressions.
NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];
Read a full article about this approach at cocoawithlove.com.
Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.
If you have to use the same page as the action, you cannot use onSubmit="window.close();"
as it will close the window before the response is received. You have to dinamycally output a JS snippet that closes the window after the SQL data is processed. It would however be far more elegant to use another page as the form action.

On Mac OS X, the Xcode developer suite includes the USB Proper.app application. This is found in /Developer/Applications/Utilities/. USB Prober will allow you to examine the device and interface descriptors.
I have used the other options described above but I find that the best is to add the following parameter to the startup of chrome.exe.
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disk-cache-size=1 -media-cache=1
I find not disabling media cache is a good idea but it is here for completeness sake.
In actuality I want an option to completely disable the cache, to use the memory for IO instead of my disk (which would make load time 10x faster too!) but I don't think chrome or any browser for that matter has that option yet.
Containment :- Here to access inner object we have to use outer object. We can reuse the contained object. Aggregation :- Here we can access inner object again and again without using outer object.
Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.
First, click Slide Show > Set Up Show.
Put a checkmark to Loop continuously until 'Esc'.
Click Ok. Now, Click Slide Show > Custom Shows. Click New.
Select the slide you are looping, click Add. Click Ok and Close.
Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.
Right click on the thumbnail of the current slide, select Hide Slide.
Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"
This has worked for me.
If you treat the content as text, not HTML, then DOM operations should cause the data to be properly encoded. Here's how you'd do it in jQuery:
$('#container').text(xmlString);
Here's how you'd do it with standard DOM methods:
document.getElementById('container')
.appendChild(document.createTextNode(xmlString));
If you're placing the XML inside of HTML through server-side scripting, there are bound to be encoding functions to allow you to do that (if you add what your server-side technology is, we can give you specific examples of how you'd do it).
In latest IntelliJ versions, you should run it from Analyze->Run Inspection By Name:

Here is a generalized simple command argument interface you can paste to the top of all your scripts.
#!/bin/bash
declare -A flags
declare -A booleans
args=()
while [ "$1" ];
do
arg=$1
if [ "${1:0:1}" == "-" ]
then
shift
rev=$(echo "$arg" | rev)
if [ -z "$1" ] || [ "${1:0:1}" == "-" ] || [ "${rev:0:1}" == ":" ]
then
bool=$(echo ${arg:1} | sed s/://g)
booleans[$bool]=true
echo \"$bool\" is boolean
else
value=$1
flags[${arg:1}]=$value
shift
echo \"$arg\" is flag with value \"$value\"
fi
else
args+=("$arg")
shift
echo \"$arg\" is an arg
fi
done
echo -e "\n"
echo booleans: ${booleans[@]}
echo flags: ${flags[@]}
echo args: ${args[@]}
echo -e "\nBoolean types:\n\tPrecedes Flag(pf): ${booleans[pf]}\n\tFinal Arg(f): ${booleans[f]}\n\tColon Terminated(Ct): ${booleans[Ct]}\n\tNot Mentioned(nm): ${boolean[nm]}"
echo -e "\nFlag: myFlag => ${flags["myFlag"]}"
echo -e "\nArgs: one: ${args[0]}, two: ${args[1]}, three: ${args[2]}"
By running the command:
bashScript.sh firstArg -pf -myFlag "my flag value" secondArg -Ct: thirdArg -f
The output will be this:
"firstArg" is an arg
"pf" is boolean
"-myFlag" is flag with value "my flag value"
"secondArg" is an arg
"Ct" is boolean
"thirdArg" is an arg
"f" is boolean
booleans: true true true
flags: my flag value
args: firstArg secondArg thirdArg
Boolean types:
Precedes Flag(pf): true
Final Arg(f): true
Colon Terminated(Ct): true
Not Mentioned(nm):
Flag: myFlag => my flag value
Args: one => firstArg, two => secondArg, three => thirdArg
Basically, the arguments are divided up into flags booleans and generic arguments. By doing it this way a user can put the flags and booleans anywhere as long as he/she keeps the generic arguments (if there are any) in the specified order.
Allowing me and now you to never deal with bash argument parsing again!
You can view an updated script here
This has been enormously useful over the last year. It can now simulate scope by prefixing the variables with a scope parameter.
Just call the script like
replace() (
source $FUTIL_REL_DIR/commandParser.sh -scope ${FUNCNAME[0]} "$@"
echo ${replaceFlags[f]}
echo ${replaceBooleans[b]}
)
Doesn't look like I implemented argument scope, not sure why I guess I haven't needed it yet.
This is called modular exponentiation(https://en.wikipedia.org/wiki/Modular_exponentiation).
Let's assume you have the following expression:
19 ^ 3 mod 7
Instead of powering 19 directly you can do the following:
(((19 mod 7) * 19) mod 7) * 19) mod 7
But this can take also a long time due to a lot of sequential multipliations and so you can multiply on squared values:
x mod N -> x ^ 2 mod N -> x ^ 4 mod -> ... x ^ 2 |log y| mod N
Modular exponentiation algorithm makes assumptions that:
x ^ y == (x ^ |y/2|) ^ 2 if y is even
x ^ y == x * ((x ^ |y/2|) ^ 2) if y is odd
And so recursive modular exponentiation algorithm will look like this in java:
/**
* Modular exponentiation algorithm
* @param x Assumption: x >= 0
* @param y Assumption: y >= 0
* @param N Assumption: N > 0
* @return x ^ y mod N
*/
public static long modExp(long x, long y, long N) {
if(y == 0)
return 1 % N;
long z = modExp(x, Math.abs(y/2), N);
if(y % 2 == 0)
return (long) ((Math.pow(z, 2)) % N);
return (long) ((x * Math.pow(z, 2)) % N);
}
Special thanks to @chux for found mistake with incorrect return value in case of y and 0 comparison.
I was looking for a solution to make the contents of a row behave like in a fixed width container, but with shrinking browser width make a minimal margin from the left (in my case: so that the row contents do not hide under a big logo with position: absolute
in left-top).
This is what worked for me:
HTML
<div class="parent-container">
<div class="child-container">
<h1>Some header</h1>
</div>
</div>
CSS
.parent-container {
padding-left: min(150px);
}
.child-container {
padding-left: calc( 50vw - 500px );
}
When I scale the browser window left and right, my h1
doesn't go to the left more than the 150px
, but goes right following the behavior of my next row's content set to display in a fixed container.

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment
to your bean.
@Autowired
private Environment environment;
....
this.environment.getActiveProfiles();
This works for me to reduce select tag's width;
<select id ="Select1" class="input-small">
You can use any one of these classes;
class="input-small"
class="input-medium"
class="input-large"
class="input-xlarge"
class="input-xxlarge"
The idea is to put files that are specific to your project into the .gitignore
file and (as already mentioned) add it to the repository. For example .pyc
and .o
files, logs that the testsuite creates, some fixtures etc.
For files that your own setup creates but which will not necessarily appear for every user (like .swp
files if you use vim, hidden ecplise directories and the like), you should use .git/info/exclude
(as already mentioned).
You can use DHP to do this. It is absolutely simple and it is fast than script.
Just write alert('something');
It is not programing language it is something like a lit bit jquery. You need require dhp.php in the top and in the bottom require dhpjs.php.
For now it is not open source but when it is you can use it. It is our programing language ;)
If you are writing code in Swift it would look as an example like this
func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String?
{
switch section
{
case 0:
return "Apple Devices"
case 1:
return "Samsung Devices"
default:
return "Other Devices"
}
}
use INSERT IGNORE INTO table
see http://bogdan.org.ua/2007/10/18/mysql-insert-if-not-exists-syntax.html
there's also INSERT … ON DUPLICATE KEY UPDATE
syntax, you can find explanations on dev.mysql.com
Post from bogdan.org.ua according to Google's webcache:
18th October 2007
To start: as of the latest MySQL, syntax presented in the title is not possible. But there are several very easy ways to accomplish what is expected using existing functionality.
There are 3 possible solutions: using INSERT IGNORE, REPLACE, or INSERT … ON DUPLICATE KEY UPDATE.
Imagine we have a table:
CREATE TABLE `transcripts` ( `ensembl_transcript_id` varchar(20) NOT NULL, `transcript_chrom_start` int(10) unsigned NOT NULL, `transcript_chrom_end` int(10) unsigned NOT NULL, PRIMARY KEY (`ensembl_transcript_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1;
Now imagine that we have an automatic pipeline importing transcripts meta-data from Ensembl, and that due to various reasons the pipeline might be broken at any step of execution. Thus, we need to ensure two things:
repeated executions of the pipeline will not destroy our database
repeated executions will not die due to ‘duplicate primary key’ errors.
Method 1: using REPLACE
It’s very simple:
REPLACE INTO `transcripts` SET `ensembl_transcript_id` = 'ENSORGT00000000001', `transcript_chrom_start` = 12345, `transcript_chrom_end` = 12678;
If the record exists, it will be overwritten; if it does not yet exist, it will be created. However, using this method isn’t efficient for our case: we do not need to overwrite existing records, it’s fine just to skip them.
Method 2: using INSERT IGNORE Also very simple:
INSERT IGNORE INTO `transcripts` SET `ensembl_transcript_id` = 'ENSORGT00000000001', `transcript_chrom_start` = 12345, `transcript_chrom_end` = 12678;
Here, if the ‘ensembl_transcript_id’ is already present in the database, it will be silently skipped (ignored). (To be more precise, here’s a quote from MySQL reference manual: “If you use the IGNORE keyword, errors that occur while executing the INSERT statement are treated as warnings instead. For example, without IGNORE, a row that duplicates an existing UNIQUE index or PRIMARY KEY value in the table causes a duplicate-key error and the statement is aborted.”.) If the record doesn’t yet exist, it will be created.
This second method has several potential weaknesses, including non-abortion of the query in case any other problem occurs (see the manual). Thus it should be used if previously tested without the IGNORE keyword.
Method 3: using INSERT … ON DUPLICATE KEY UPDATE:
Third option is to use
INSERT … ON DUPLICATE KEY UPDATE
syntax, and in the UPDATE part just do nothing do some meaningless (empty) operation, like calculating 0+0 (Geoffray suggests doing the id=id assignment for the MySQL optimization engine to ignore this operation). Advantage of this method is that it only ignores duplicate key events, and still aborts on other errors.As a final notice: this post was inspired by Xaprb. I’d also advise to consult his other post on writing flexible SQL queries.
I've had this problem before, and the solution is simply to call window.print() in IE, as opposed to calling print from the window instance:
function printPage(htmlPage)
{
var w = window.open("about:blank");
w.document.write(htmlPage);
if (navigator.appName == 'Microsoft Internet Explorer') window.print();
else w.print();
}
I ran into this bugger too.
I was running an older version of Xcode (not compatible with ios 9.2) so I needed to update.
I spent hours on this and was constantly getting spinning wheel of death in the app store. Nothing worked. I tried CLI softwareupdate, updating OSX, everything.
I ultimately had to download AppZapper, then nuked XCode.
I went into the app store to download and it still didn't work. Then I rebooted.
And from here I could finally upgrade to a fresh version of xcode.
WARNING: AppZapper can delete all your data around Xcode as well, so be prepared to start from scratch on your profiles, keys, etc. Also per the other notes here, of course be ready for a 3-5 hour long downloading expedition...
You want $_SERVER['REQUEST_URI']
. From the docs:
'REQUEST_URI'
The URI which was given in order to access this page; for instance,
'/index.html'
.
The following will solve your problem:
td.last {
width: 1px;
white-space: nowrap;
}
And a more flexible solution is creating a .fitwidth
class and applying that to any columns you want to ensure their contents are fit on one line:
td.fitwidth {
width: 1px;
white-space: nowrap;
}
And then in your HTML:
<tr>
<td class="fitwidth">ID</td>
<td>Description</td>
<td class="fitwidth">Status</td>
<td>Notes</td>
</tr>

If you prefer attr_accessible, you could use it in Rails 4 too. You should install it like gem:
gem 'protected_attributes'
after that you could use attr_accessible in you models like in Rails 3
Also, and i think that is the best way- using form objects for dealing with mass assignment, and saving nested objects, and you can also use protected_attributes gem that way
class NestedForm
include ActiveModel::MassAssignmentSecurity
attr_accessible :name,
:telephone, as: :create_params
def create_objects(params)
SomeModel.new(sanitized_params(params, :create_params))
end
end
I am the author of a small library that does exactly what you want:
Student student = new Student("Andrei", 30, "Male");
String studStr = template("#{id}\tName: #{st.getName}, Age: #{st.getAge}, Gender: #{st.getGender}")
.arg("id", 10)
.arg("st", student)
.format();
System.out.println(studStr);
Or you can chain the arguments:
String result = template("#{x} + #{y} = #{z}")
.args("x", 5, "y", 10, "z", 15)
.format();
System.out.println(result);
// Output: "5 + 10 = 15"
If like me you need to do this all the time, you can set up an alias to do it automatically by adding the following to your .gitconfig
file:
[alias]
set-upstream = !git branch --set-upstream-to=origin/`git symbolic-ref --short HEAD`
When you see the message There is no tracking information...
, just run git set-upstream
, then git push
again.
Google Maps API v3:
I initialized Google Map and added markers to it. Later, I wanted to retrieve all markers and did it simply by accessing the map property "markers".
var map = new GMaps({
div: '#map',
lat: 40.730610,
lng: -73.935242,
});
var myMarkers = map.markers;
You can loop over it and access all Marker methods listed at Google Maps Reference.
The volume it's on is mounted noexec
.
The same applies to stdout:
print 'spam'
sys.stdout.write('spam\n')
As stated in the other answers, print offers a pretty interface that is often more convenient (e.g. for printing debug information), while write is faster and can also be more convenient when you have to format the output exactly in certain way. I would consider maintainability as well:
You may later decide to switch between stdout/stderr and a regular file.
print() syntax has changed in Python 3, so if you need to support both versions, write() might be better.
You are not able to return 'multiple values' in PHP. You can return a single value, which might be an array.
function foo($test1, $test2, $test3)
{
return array($test1, $test2, $test3);
}
$test1 = "1";
$test2 = "2";
$test3 = "3";
$arr = foo($test1, $test2, $test3);
$test1 = $arr[0];
$test2 = $arr[1];
$test3 = $arr[2];

Pseudo-elements are treated as descendants of their associated element. To position a pseudo-element below its parent, you have to create a new stacking context to change the default stacking order.
Positioning the pseudo-element (absolute) and assigning a z-index value other than “auto” creates the new stacking context.
#element { _x000D_
position: relative; /* optional */_x000D_
width: 100px;_x000D_
height: 100px;_x000D_

I have multiple routes and multiple controllers, so I could not get the accepted answer to work. I found that adding the function to the window works:
fooModule.controller("fooViewModel", function ($scope, fooService, $http, $q, $routeParams, $window, $location, viewModelHelper, $interval) {
$scope.initFoo = function () {
// do angular stuff
}
var initialize = function () {
$scope.initFoo();
}
initialize();
window.fooreinit = initialize;
}
Then outside the controller, this can be done:
function ElsewhereOnThePage() {
if (typeof(fooreinit) == 'function') { fooreinit(); }
}

To retrieve the entire querystring from the current URL, beginning with the ?
character, you can use
location.search
https://developer.mozilla.org/en-US/docs/DOM/window.location
Example:
// URL = https://example.com?a=a%20a&b=b123
console.log(location.search); // Prints "?a=a%20a&b=b123"
In regards to retrieving specific querystring parameters, while although classes like URLSearchParams
and URL
exist, they aren't supported by Internet Explorer at this time, and should probably be avoided. Instead, you can try something like this:
/**
* Accepts either a URL or querystring and returns an object associating
* each querystring parameter to its value.
*
* Returns an empty object if no querystring parameters found.
*/
function getUrlParams(urlOrQueryString) {
if ((i = urlOrQueryString.indexOf('?')) >= 0) {
const queryString = urlOrQueryString.substring(i+1);
if (queryString) {
return _mapUrlParams(queryString);
}
}
return {};
}
/**
* Helper function for `getUrlParams()`
* Builds the querystring parameter to value object map.
*
* @param queryString {string} - The full querystring, without the leading '?'.
*/
function _mapUrlParams(queryString) {
return queryString
.split('&')
.map(function(keyValueString) { return keyValueString.split('=') })
.reduce(function(urlParams, [key, value]) {
if (Number.isInteger(parseInt(value)) && parseInt(value) == value) {
urlParams[key] = parseInt(value);
} else {
urlParams[key] = decodeURI(value);
}
return urlParams;
}, {});
}
You can use the above like so:
// Using location.search
let urlParams = getUrlParams(location.search); // Assume location.search = "?a=1&b=2b2"
console.log(urlParams); // Prints { "a": 1, "b": "2b2" }
// Using a URL string
const url = 'https://example.com?a=A%20A&b=1';
urlParams = getUrlParams(url);
console.log(urlParams); // Prints { "a": "A A", "b": 1 }
// To check if a parameter exists, simply do:
if (urlParams.hasOwnProperty('parameterName') {
console.log(urlParams.parameterName);
}
Simply create a .bat file with the following lines in it:
@ECHO OFF
set CLASSPATH=.
set CLASSPATH=%CLASSPATH%;path/to/needed/jars/my.jar
%JAVA_HOME%\bin\java -Xms128m -Xmx384m -Xnoclassgc ro.my.class.MyClass
Remove these two lines:
xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");
XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.
If you just want your query data dumped into excel I have to do this frequently and using an html table is a very simple method. I use mysqli for db queries and the following code for exports to excel:
header("Content-Type: application/xls");
header("Content-Disposition: attachment; filename=filename.xls");
header("Pragma: no-cache");
header("Expires: 0");
echo '<table border="1">';
//make the column headers what you want in whatever order you want
echo '<tr><th>Field Name 1</th><th>Field Name 2</th><th>Field Name 3</th></tr>';
//loop the query data to the table in same order as the headers
while ($row = mysqli_fetch_assoc($result)){
echo "<tr><td>".$row['field1']."</td><td>".$row['field2']."</td><td>".$row['field3']."</td></tr>";
}
echo '</table>';
Here's a collection of scripts: http://webtecker.com/2008/03/26/collection-of-password-strength-scripts/
I think both of them rate the password and don't use jQuery... but I don't know if they have native support for disabling the form?
The password of keystore by default is: "changeit". I functioned to my commands you entered here, for the import of the certificate. I hope you have already solved your problem.
since you only want values copied, you can pass the values of arr1 directly to arr2 and avoid copy/paste. code inside the loop:
Sheets("SheetB").Range(arr2(i) & firstrowDB).Resize(lastrow, 1).Value = .Range(.Cells(1, arr1(i)), .Cells(lastrow, arr1(i))).Value
As you have define the id in int type at the database creation, you have to use the same data type in the model class too. And as you have defined the id to auto increment in the database, you have to mention it in the model class by passing value 'GenerationType.AUTO' into the attribute 'strategy' within the annotation @GeneratedValue. Then the code becomes as below.
@Entity
public class Operator{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
private String username;
private String password;
private Integer active;
//Getters and setters...
}
Assuming the first answer is referring to the C-like syntax (char *)(0x135700 +0xec1a04f)
then the answer to do rwatch *0x135700+0xec1a04f
is incorrect. The correct syntax is rwatch *(0x135700+0xec1a04f)
.
The lack of ()
s there caused me a great deal of pain trying to use watchpoints myself.
change your jquery method to
$(function () { /* DOM ready */
$("#type").change(function () {
alert('The option with value ' + $(this).val());
//hide the element you want to hide here with
//("id").attr("display","block"); // to show
//("id").attr("display","none"); // to hide
});
});
That's right, if you're on a mac(unix) you won't see .git in finder(the file browser). You can follow the directions above to delete and there are git commands that allow you to delete files as well(they are sometimes difficult to work with and learn, for example: on making a 'git rm -r ' command you might be prompted with a .git/ not found. Here is the git command specs:
usage: git rm [options] [--] ...
-n, --dry-run dry run
-q, --quiet do not list removed files
--cached only remove from the index
-f, --force override the up-to-date check
-r allow recursive removal
--ignore-unmatch exit with a zero status even if nothing matched
When I had to do this, deleting the objects and refs didn't matter. After I deleted the other files in the .git, I initialized a git repo with 'git init' and it created an empty repo.
This worked for me-
if(Mage::registry('current_product')->getTypeId() == 'simple' ) {

Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.
Update:
It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.
If you want the types of convenience methods mentioned in other answers but need portability (or even if you don't), you might want to check out Flurl [disclosure: I'm the author]. It (thinly) wraps HttpClient
and Json.NET and adds some fluent sugar and other goodies, including some baked-in testing helpers.
Post as JSON:
var resp = await "http://localhost:44268/api/test".PostJsonAsync(widget);
or URL-encoded:
var resp = await "http://localhost:44268/api/test".PostUrlEncodedAsync(widget);
Both examples above return an HttpResponseMessage
, but Flurl includes extension methods for returning other things if you just want to cut to the chase:
T poco = await url.PostJsonAsync(data).ReceiveJson<T>();
dynamic d = await url.PostUrlEncodedAsync(data).ReceiveJson();
string s = await url.PostUrlEncodedAsync(data).ReceiveString();
Flurl is available on NuGet:
PM> Install-Package Flurl.Http
Code posted by you is correct and should have worked. But check exactly what you have in the char*
. If the correct value is to big to be represented, functions will return a positive or negative HUGE_VAL
. Check what you have in the char*
against maximum values that float
and double
can represent on your computer.
Check this page for strtod
reference and this page for atof
reference.
I have tried the example you provided in both Windows and Linux and it worked fine.
try to compile
compile 'com.android.support:cardview-v7:25.3.1'
Well, the "failure sending e-mail" should hopefully have a bit more detail. But there are a few things that could cause this.
Regardless if it is one of these or another error, you will want to look at the exception and inner exception to get a bit more detail.
The compiler may add padding for alignment requirements. Note that this applies not only to padding between the fields of a struct, but also may apply to the end of the struct (so that arrays of the structure type will have each element properly aligned).
For example:
struct foo_t {
int x;
char c;
};
Even though the c
field doesn't need padding, the struct will generally have a sizeof(struct foo_t) == 8
(on a 32-bit system - rather a system with a 32-bit int
type) because there will need to be 3 bytes of padding after the c
field.
Note that the padding might not be required by the system (like x86 or Cortex M3) but compilers might still add it for performance reasons.
HashSet<String>
(or) any Set
implementation may does the job for you. Set
don't allow duplicates.

Just omit the [Required] attribute from the string somefield
property. This will make it create a NULL
able column in the db.
To make int types allow NULLs in the database, they must be declared as nullable ints in the model:
// an int can never be null, so it will be created as NOT NULL in db
public int someintfield { get; set; }
// to have a nullable int, you need to declare it as an int?
// or as a System.Nullable<int>
public int? somenullableintfield { get; set; }
public System.Nullable<int> someothernullableintfield { get; set; }

For those of you who hit this stackoverflow entry because it ranks high for the phrase:

In my personal situation with this exact error message, I had turned on python 2.7 thinking I could use some python with my .NET API. I then had that exact error message when I attempted to deploy a vanilla version of the API or MVC from visual studio pro 2013. I was deploying to an azure cloud webapp.
Hope this helps anyone with my same experience. I didn't even think to turn off python until I found this suggestion.
Yes, although Internet Explorer 9 will compile your Javascript on a separate thread in preparation for execution on the main thread. This doesn't change anything for you as a programmer, though.
In addition to the accepted answer I would like to give an answer that shows how to iterate directly over the Newtonsoft collections. It uses less code and I'm guessing its more efficient as it doesn't involve converting the collections.
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
//Parse the data
JObject my_obj = JsonConvert.DeserializeObject<JObject>(your_json);
foreach (KeyValuePair<string, JToken> sub_obj in (JObject)my_obj["ADDRESS_MAP"])
{
Console.WriteLine(sub_obj.Key);
}
I started doing this myself because JsonConvert automatically deserializes nested objects as JToken (which are JObject, JValue, or JArray underneath I think).
I think the parsing works according to the following principles:
Every object is abstracted as a JToken
Cast to JObject where you expect a Dictionary
Cast to JValue if the JToken represents a terminal node and is a value
Cast to JArray if its an array
JValue.Value gives you the .NET type you need
You can use negative integers with the slicing operator for that. Here's an example using the python CLI interpreter:
>>> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a[-9:]
[4, 5, 6, 7, 8, 9, 10, 11, 12]
the important line is a[-9:]

The returnedData is returning an array of objects, so you can access it by array index.
Usually this is caused by shell initialization files. Search for PATH=... entries.
You can also re-add RVM to your profile by running: rvm get stable --auto-dotfiles
To fix it temporarily in this shell session run: rvm use ruby-2.6.5
To ignore this error add "rvm_silence_path_mismatch_check_flag=1" to your "~/.rvmrc" file.
On windows you can use Drip.exe to find memory leaks or check if your free mem routine works.
It's really simple, just enter a website URL and you will see the memory consumption of the integrated IE renderer. Then hit refresh, if the memory increases, you found a memory leak somewhere on the webpage. But this is also very useful to see if routines for freeing memory work for IE.
Recently, I have seen this problem too. Below, you have my solution:
Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart
or fix it up
I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):
ssh -T [email protected]
Upon receiving a successful response, I could fetch/push to the repo with ssh.
I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.
By compiling answers from @Robse and @DanH (kudos!), I've got the following solution which completely satisfies me:
db.getCollectionNames().forEach( function(collection_name) {
if (collection_name.indexOf("system.") == -1)
db[collection_name].drop();
else
db.collection_name.remove({});
});
Connect to you database, run the code.
It cleans the database by dropping the user collections and emptying the system collections.
Yes, but then what do you do about the django objects? simple json tends to choke on them.
If the objects are individual model objects (not querysets, e.g.), I have occasionally stored the model object type and the pk, like so:
seralized_dict = simplejson.dumps(my_dict,
default=lambda a: "[%s,%s]" % (str(type(a)), a.pk)
)
to de-serialize, you can reconstruct the object referenced with model.objects.get(). This doesn't help if you are interested in the object details at the type the dict is stored, but it's effective if all you need to know is which object was involved.
In Retrofit 2 you should use HttpLoggingInterceptor.
Add dependency to build.gradle
. Latest version as of October 2019 is:
implementation 'com.squareup.okhttp3:logging-interceptor:4.2.1'
Create a Retrofit
object like the following:
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://backend.example.com")
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build();
return retrofit.create(ApiClient.class);
In case of deprecation warnings, simply change setLevel
to:
interceptor.level(HttpLoggingInterceptor.Level.BODY);
The above solution gives you logcat messages very similar to the old ones set by
setLogLevel(RestAdapter.LogLevel.FULL)
In case of java.lang.ClassNotFoundException
:
Older Retrofit version might require an older logging-interceptor
version. Take a look at comments sections for details.
Linux doesn't have a separate threads per process limit, just a limit on the total number of processes on the system (threads are essentially just processes with a shared address space on Linux) which you can view like this:
cat /proc/sys/kernel/threads-max
The default is the number of memory pages/4. You can increase this like:
echo 100000 > /proc/sys/kernel/threads-max
There is also a limit on the number of processes (and hence threads) that a single user may create, see ulimit/getrlimit
for details regarding these limits.
This is an issue when migrating from gulp version 3 to 4, Simply you can add a parameter done to the call back function , see example,
const gulp = require("gulp")
gulp.task("message", function(done) {
console.log("Gulp is running...")
done()
});
What is currently happening is, that you have a certain set of files, which you have tried merging earlier, but they threw up merge conflicts.
Ideally, if one gets a merge conflict, he should resolve them manually, and commit the changes using git add file.name && git commit -m "removed merge conflicts"
.
Now, another user has updated the files in question on his repository, and has pushed his changes to the common upstream repo.
It so happens, that your merge conflicts from (probably) the last commit were not not resolved, so your files are not merged all right, and hence the U
(unmerged
) flag for the files.
So now, when you do a git pull
, git is throwing up the error, because you have some version of the file, which is not correctly resolved.
To resolve this, you will have to resolve the merge conflicts in question, and add and commit the changes, before you can do a git pull
.
# Note: commands below in format `CUURENT_WORKING_DIRECTORY $ command params`
Desktop $ cd test
First, let us create the repository structure
test $ mkdir repo && cd repo && git init && touch file && git add file && git commit -m "msg"
repo $ cd .. && git clone repo repo_clone && cd repo_clone
repo_clone $ echo "text2" >> file && git add file && git commit -m "msg" && cd ../repo
repo $ echo "text1" >> file && git add file && git commit -m "msg" && cd ../repo_clone
Now we are in repo_clone, and if you do a git pull
, it will throw up conflicts
repo_clone $ git pull origin master
remote: Counting objects: 5, done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
From /home/anshulgoyal/Desktop/test/test/repo
* branch master -> FETCH_HEAD
24d5b2e..1a1aa70 master -> origin/master
Auto-merging file
CONFLICT (content): Merge conflict in file
Automatic merge failed; fix conflicts and then commit the result.
If we ignore the conflicts in the clone, and make more commits in the original repo now,
repo_clone $ cd ../repo
repo $ echo "text1" >> file && git add file && git commit -m "msg" && cd ../repo_clone
And then we do a git pull
, we get
repo_clone $ git pull
U file
Pull is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm <file>'
as appropriate to mark resolution, or use 'git commit -a'.
Note that the file
now is in an unmerged state and if we do a git status
, we can clearly see the same:
repo_clone $ git status
On branch master
Your branch and 'origin/master' have diverged,
and have 1 and 1 different commit each, respectively.
(use "git pull" to merge the remote branch into yours)
You have unmerged paths.
(fix conflicts and run "git commit")
Unmerged paths:
(use "git add <file>..." to mark resolution)
both modified: file
So, to resolve this, we first need to resolve the merge conflict we ignored earlier
repo_clone $ vi file
and set its contents to
text2
text1
text1
and then add it and commit the changes
repo_clone $ git add file && git commit -m "resolved merge conflicts"
[master 39c3ba1] resolved merge conflicts
resultString = subjectString.replaceAll("[^.\\d]", "");
will remove all characters except digits and the dot from your string.
To make it locale-aware, you might want to use getDecimalSeparator()
from java.text.DecimalFormatSymbols
. I don't know Java, but it might look like this:
sep = getDecimalSeparator()
resultString = subjectString.replaceAll("[^"+sep+"\\d]", "");
In my case, I had already generated an APK file using the command ionic cordova build android --prod
and I needed to get the SHA-1 fingerprint for the already existing APK file. Here's how I got it by running the following command in the App directory:
keytool -list -printcert -jarfile app-debug.apk
So, I basically ran the above command in the following app location:
C:\myApp\platforms\android\app\build\outputs\apk\debug>keytool -list -printcert -jarfile app-debug.apk
This gave me the SHA1 fingerprint as: 7B:6B:AD:...
Hope this helps someone!
As already mentioned, you can get a performance increase from having your python code compiled into bytecode. This is usually handled by python itself, for imported scripts only.
Another reason you might want to compile your python code, could be to protect your intellectual property from being copied and/or modified.
You can read more about this in the Python documentation.
Suppose you have following lines of code
MyUrl = "www.google.com" #Your url goes here
urllib.urlretrieve(MyUrl)
If you are receiving following error message
AttributeError: module 'urllib' has no attribute 'urlretrieve'
Then you should try following code to fix the issue:
import urllib.request
MyUrl = "www.google.com" #Your url goes here
urllib.request.urlretrieve(MyUrl)
The question is old, yet I'd like to extend the topic with another answer.
My point is, the easiest way to achieve it is just to wrap multiple queries with a transaction. The accepted answer INSERT ... ON DUPLICATE KEY UPDATE
is a nice hack, but one should be aware of its drawbacks and limitations:
"Field 'fieldname' doesn't have a default value"
MySQL warning even if you don't insert a single row at all. It will get you into trouble, if you decide to be strict and turn mysql warnings into runtime exceptions in your app.I made some performance tests for three of suggested variants, including the INSERT ... ON DUPLICATE KEY UPDATE
variant, a variant with "case / when / then" clause and a naive approach with transaction. You may get the python code and results here. The overall conclusion is that the variant with case statement turns out to be twice as fast as two other variants, but it's quite hard to write correct and injection-safe code for it, so I personally stick to the simplest approach: using transactions.
Edit: Findings of Dakusan prove that my performance estimations are not quite valid. Please see this answer for another, more elaborate research.
I also had same issue on my mac. I was running 5.3.0 version. I removed that version and installed 7.2.1 version. After this it is working in my case.

PrjForm was set to ".Net Framework 4 Client Profile" I changed it to ".Net Framework 4", and now I have a successful build.
This worked for me too. Thanks a lot. I was trying an RDF example for dotNet where in I downloaded kit from dotnetrdf.
NET4 Client Profile: Always target NET4 Client Profile for all your client desktop applications (including Windows Forms and WPF apps).
NET4 Full framework: Target NET4 Full only if the features or assemblies that your app need are not included in the Client Profile. This includes: If you are building Server apps, Such as:
If you use legacy client scenarios, Such as: o Use System.Data.OracleClient.dll which is deprecated in NET4 and not included in the Client Profile.
If you targeting developer scenarios and need tool such as MSBuild or need access to design assemblies such as System.Design.dll

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:
https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899
In this example, question 1, "Name", has an ID of 726721210
, while question 2, "Birthday" is 787184751
. Questions 3 and 4 are blank.
You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:
function buildUrls() {
var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1"); // Email, Name, Birthday
var data = ss.getDataRange().getValues();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
var url = template.replace('##Name##',escape(data[i][1]))
.replace('##Birthday##',data[i][2].yyyymmdd()); // see yyyymmdd below
Logger.log(url); // You could do something more useful here.
}
};
This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.
Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.
Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0]
is "Name", [1]
is "Birthday", and so on.
We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.
(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)
/**
* Use Form API to generate pre-filled form URLs
*/
function betterBuildUrls() {
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName("Sheet1");
var data = ss.getDataRange().getValues(); // Data for pre-fill
var formUrl = ss.getFormUrl(); // Use form attached to sheet
var form = FormApp.openByUrl(formUrl);
var items = form.getItems();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
// Create a form response object, and prefill it
var formResponse = form.createResponse();
// Prefill Name
var formItem = items[0].asTextItem();
var response = formItem.createResponse(data[i][1]);
formResponse.withItemResponse(response);
// Prefill Birthday
formItem = items[1].asDateItem();
response = formItem.createResponse(data[i][2]);
formResponse.withItemResponse(response);
// Get prefilled form URL
var url = formResponse.toPrefilledUrl();
Logger.log(url); // You could do something more useful here.
}
};
Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd
. This helper function extends the Date object with a new method to handle the conversion.
When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975
you could use 5/9/1975
.)
// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};
As far as I know, and I cant verify it now, you cannot stop remote services with the Stop-Service cmdlet or with .Net, it is not supported.
Yes it works, but it stopes the service on your local machine, not on the remote computer.
Now, if the above is correct, without remoting or wmi enabled, you could set a scheduled job on the remote system, using AT, that runs Stop-Service locally.
just change the extension to .bmp.
Do this:
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
_bitmapScaled.compress(Bitmap.CompressFormat.PNG, 40, bytes);
//you can create a new file name "test.BMP" in sdcard folder.
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + "test.bmp")
It'll sound that I'm just fooling around, but try it once and it'll get saved in BMP
format. Cheers!
Sometimes it's knowing what to ask. I didn't know as I am a developer who has taken on some DevOps work.
Apparently 'passwordless' or NOPASSWD login is a thing which you need to put in the /etc/sudoers file.
The answer to my question is at Ansible: best practice for maintaining list of sudoers.
The Ansible playbook code fragment looks like this from my problem:
- name: Make sure we have a 'wheel' group
group:
name: wheel
state: present
- name: Allow 'wheel' group to have passwordless sudo
lineinfile:
dest: /etc/sudoers
state: present
regexp: '^%wheel'
line: '%wheel ALL=(ALL) NOPASSWD: ALL'
validate: 'visudo -cf %s'
- name: Add sudoers users to wheel group
user:
name=deployer
groups=wheel
append=yes
state=present
createhome=yes
- name: Set up authorized keys for the deployer user
authorized_key: user=deployer key="{{item}}"
with_file:
- /home/railsdev/.ssh/id_rsa.pub
And the best part is that the solution is idempotent. It doesn't add the line
%wheel ALL=(ALL) NOPASSWD: ALL
to /etc/sudoers when the playbook is run a subsequent time. And yes...I was able to ssh into the server as "deployer" and run sudo commands without having to give a password.
The issue is with this line
xlo.Worksheets(1).Cells(2, 2) = TextBox1.Text
You have the textbox defined at some other location which you are not using here. Excel is unable to find the textbox object in the current sheet while this textbox was defined in xlw.
Hence replace this with
xlo.Worksheets(1).Cells(2, 2) = worksheets("xlw").TextBox1.Text
The normal apporoach works the other way around: You create your build based upon maven or ant and then use integrations for your IDE of choice so that you are independent from it, which is esp. important when you try to bring new team members up to speed or use a contious integration server for automated builds. I recommend to use maven and let it do the heavy lifting for you. Create a pom file and generate the eclipse project via mvn eclipse:eclipse. HTH
Please check the sample code for the Google Maps Android API v2. Using this will solve your problem.
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
mMap.setMyLocationEnabled(true);
// Check if we were successful in obtaining the map.
if (mMap != null) {
mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
@Override
public void onMyLocationChange(Location arg0) {
mMap.addMarker(new MarkerOptions().position(new LatLng(arg0.getLatitude(), arg0.getLongitude())).title("It's Me!"));
}
});
}
}
}
Call this function in onCreate
function.
Hope it will help someone someday. I was making a small POC and came across this. A button, onClick display contents of the folder. Below is the HTML,
<input type=button onClick="parent.location='file:///C:/Users/' " value='Users'>
The accepted answer is missing a point:
{
let a = 123;
};
console.log(a); // ReferenceError: a is not defined
The only way I could get this to work is to pass the JSON as a string and then deserialise it using JavaScriptSerializer.Deserialize<T>(string input)
, which is pretty strange if that's the default deserializer for MVC 4.
My model has nested lists of objects and the best I could get using JSON data is the uppermost list to have the correct number of items in it, but all the fields in the items were null.
This kind of thing should not be so hard.
$.ajax({
type: 'POST',
url: '/Agri/Map/SaveSelfValuation',
data: { json: JSON.stringify(model) },
dataType: 'text',
success: function (data) {
[HttpPost]
public JsonResult DoSomething(string json)
{
var model = new JavaScriptSerializer().Deserialize<Valuation>(json);
