There is special method:
a.unshift(value);
But if you want to prepend several elements to array it would be faster to use such a method:
var a = [1, 2, 3],
b = [4, 5];
function prependArray(a, b) {
var args = b;
args.unshift(0);
args.unshift(0);
Array.prototype.splice.apply(a, args);
}
prependArray(a, b);
console.log(a); // -> [4, 5, 1, 2, 3]
Extending on what @vabhatia said, this is what you want in native JavaScript (without JQuery).
ParentNode.insertBefore(<your element>, ParentNode.firstChild);
If someone finds this question like me, here are my performance tests of proposed methods:
Python 2.7.8
In [1]: %timeit ([1]*1000000).insert(0, 0)
100 loops, best of 3: 4.62 ms per loop
In [2]: %timeit ([1]*1000000)[0:0] = [0]
100 loops, best of 3: 4.55 ms per loop
In [3]: %timeit [0] + [1]*1000000
100 loops, best of 3: 8.04 ms per loop
As you can see, insert
and slice assignment are as almost twice as fast than explicit adding and are very close in results. As Raymond Hettinger noted insert
is more common option and I, personally prefer this way to prepend to list.
This is not best way to do it but if anyone wants to insert an element before everything, here is a way.
var newElement = document.createElement("div");
var element = document.getElementById("targetelement");
element.innerHTML = '<div style="display:none !important;"></div>' + element.innerHTML;
var referanceElement = element.children[0];
element.insertBefore(newElement,referanceElement);
element.removeChild(referanceElement);
The best way is going to documentation.
.append()
vs .after()
append()
: Insert content, specified by the parameter, to the end of each element in the set of matched elements.after()
: Insert content, specified by the parameter, after each element in the set of matched elements. .prepend()
vs .before()
prepend()
: Insert content, specified by the parameter, to the beginning of each element in the set of matched elements.before()
: Insert content, specified by the parameter, before each element in the set of matched elements.So, append and prepend refers to child of the object whereas after and before refers to sibling of the the object.
The C compiler can glue adjacent string literals into one, like
printf("foo: %s "
"bar: %d", foo, bar);
The preprocessor can use a backslash as a last character of the line, not counting CR (or CR/LF, if you are from Windowsland):
printf("foo %s \
bar: %d", foo, bar);
This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.
In standard SQL one would write:
SELECT t0.foo, t1.bar
FROM FIRST_TABLE t0
RIGHT OUTER JOIN SECOND_TABLE t1;
Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :
Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]
You are looking for display:
document.getElementById("endTimeLabel").style.display = 'none';
document.getElementById("endTimeLabel").style.display = 'block';
Edit: You could also easily reuse your validation function.

<span id="startDateLabel">Start date/time: </span>
<input id="startDateStr" name="startDateStr" size="8" onchange="if (!formatDate(this,'USA')) {this.value = '';}" />
<button id="startDateCalendarTrigger">...</button>
<input id="startDateTime" type="text" size="8" name="startTime" value="12:00 AM" onchange="validateHHMM(this.value, 'startTimeLabel');"/>
<label id="startTimeLabel" class="errorMsg">Time must be entered in the format HH:MM AM/PM</label><br />
<span id="endDateLabel">End date/time: </span>
<input id="endDateStr" name="endDateStr" size="8" onchange="if (!formatDate(this,'USA')) {this.value = '';}" />
<button id="endDateCalendarTrigger">...</button>
<input id="endDateTime" type="text" size="8" name="endTime" value="12:00 AM" onchange="validateHHMM(this.value, 'endTimeLabel');"/>
<label id="endTimeLabel" class="errorMsg">Time must be entered in the format HH:MM AM/PM</label>
Javascript:
function validateHHMM(value, message) {
var isValid = /^(0?[1-9]|1[012])(:[0-5]\d) [APap][mM]$/.test(value);
if (isValid) {
document.getElementById(message).style.display = "none";
}else {
document.getElementById(message).style.display= "inline";
}
return isValid;
}
In case it helps, I've ran into this problem when passing null
into a parameter for a generic TValue
, to get around this you have to cast your null values:
(string)null
(int)null
etc.

By implementing ImplicitNamingStrategy
you may create rules for automatically naming the constraints. Note you add your naming strategy to the metadataBuilder
during Hibernate's initialization:
metadataBuilder.applyImplicitNamingStrategy(new MyImplicitNamingStrategy());
It works for @UniqueConstraint
, but not for @Column(unique = true)
, which always generates a random name (e.g. UK_3u5h7y36qqa13y3mauc5xxayq).
There is a bug report to solve this issue, so if you can, please vote there to have this implemented. Here: https://hibernate.atlassian.net/browse/HHH-11586

Insert can only operate on one table at a time. Multiple Inserts have to have multiple statements.
I don't know that you need to do the looping through a table variable - can't you just use a mass insert into one table, then the mass insert into the other?
By the way - I am guessing you mean copy the data from Object_Table; otherwise the question does not make sense.
In python, everything is an object, also "simple" variables types (int, float, etc..).
When you changes a variable value, you actually changes it's pointer, and if you compares between two variables it's compares their pointers. (To be clear, pointer is the address in physical computer memory where a variable is stored).
As a result, when you changes an inner variable value, you changes it's value in the memory and it's affects all the variables that point to this address.
For your example, when you do:
a = b = 5
This means that a and b points to the same address in memory that contains the value 5, but when you do:
a = 6
It's not affect b because a is now points to another memory location that contains 6 and b still points to the memory address that contains 5.
But, when you do:
a = b = [1,2,3]
a and b, again, points to the same location but the difference is that if you change the one of the list values:
a[0] = 2
It's changes the value of the memory that a is points on, but a is still points to the same address as b, and as a result, b changes as well.
button.setBackgroundColor(getResources().getColor(R.color.red);

You code is ok only except that you can't add same class test1
.
$('.page-address-edit').addClass('test1').addClass('test2'); //this will add test1 and test2
And you could also do
$('.page-address-edit').addClass('test1 test2');
Your code should be:
public class Project extends Activity implements OnClickListener {
/** Called when the activity is first created. */
EditText editText;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
editText = (EditText)findViewById(R.id.editText1);
editText.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v == editText) {
editText.setText("");
}
}
}
You are missing a comma after
'data': { 'request': "", 'target': 'arrange_url', 'method': 'method_target' }
Also, if you want return_first
to hold the result of your anonymous function, you need to make a function call:
var return_first = function () {
var tmp = null;
$.ajax({
'async': false,
'type': "POST",
'global': false,
'dataType': 'html',
'url': "ajax.php?first",
'data': { 'request': "", 'target': 'arrange_url', 'method': 'method_target' },
'success': function (data) {
tmp = data;
}
});
return tmp;
}();
Note ()
at the end.

You should convert them to number before compare.
Try:
if (+x > +y) {
//...
}
or
if (Number(x) > Number(y)) {
// ...
}
Note: parseFloat
and pareseInt
(for compare integer, and you need to specify the radix) will give you NaN
for an empty string, compare with NaN
will always be false
, If you don't want to treat empty string be 0
, then you could use them.
Perhaps something that's not been mentioned is that of locality.
A MAC address or time-based ordering (UUID1) can afford increased database performance, since it's less work to sort numbers closer-together than those distributed randomly (UUID4) (see here).
A second related issue, is that using UUID1 can be useful in debugging, even if origin data is lost or not explicitly stored (this is obviously in conflict with the privacy issue mentioned by the OP).
character varying(n)
, varchar(n)
- (Both the same). value will be truncated to n characters without raising an error.
character(n)
, char(n)
- (Both the same). fixed-length and will pad with blanks till the end of the length.
text
- Unlimited length.
Example:
Table test:
a character(7)
b varchar(7)
insert "ok " to a
insert "ok " to b
We get the results:
a | (a)char_length | b | (b)char_length
----------+----------------+-------+----------------
"ok "| 7 | "ok" | 2

# No-op if the path is already absolute.

The best option for your specific case might be:
Right before your close </body>
tag:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="js/vendor/jquery-1.10.2.min.js"><\/script>')</script>
This is probably the easiest way given that your issue is centered around jQuery.
If you wanted a more robust solution you could try:
var online = navigator.onLine;
Read more about the W3C's spec on offline web apps, however be aware that this will work best in modern web browsers, doing so with older web browsers may not work as expected, or at all.
Alternatively, an XHR request to your own server isn't that bad of a method for testing your connectivity. Considering one of the other answers state that there are too many points of failure for an XHR, if your XHR is flawed when establishing it's connection then it'll also be flawed during routine use anyhow. If your site is unreachable for any reason, then your other services running on the same servers will likely be unreachable also. That decision is up to you.
I wouldn't recommend making an XHR request to someone else's service, even google.com for that matter. Make the request to your server, or not at all.
There seems to be some confusion around what being "online" means. Consider that the internet is a bunch of networks, however sometimes you're on a VPN, without access to the internet "at-large" or the world wide web. Often companies have their own networks which have limited connectivity to other external networks, therefore you could be considered "online". Being online only entails that you are connected to a network, not the availability nor reachability of the services you are trying to connect to.
To determine if a host is reachable from your network, you could do this:
function hostReachable() {
// Handle IE and more capable browsers
var xhr = new ( window.ActiveXObject || XMLHttpRequest )( "Microsoft.XMLHTTP" );
// Open new request as a HEAD to the root hostname with a random param to bust the cache
xhr.open( "HEAD", "//" + window.location.hostname + "/?rand=" + Math.floor((1 + Math.random()) * 0x10000), false );
// Issue request and handle response
try {
xhr.send();
return ( xhr.status >= 200 && (xhr.status < 300 || xhr.status === 304) );
} catch (error) {
return false;
}
}
You can also find the Gist for that here: https://gist.github.com/jpsilvashy/5725579
Details on local implementation
Some people have commented, "I'm always being returned false". That's because you're probably testing it out on your local server. Whatever server you're making the request to, you'll need to be able to respond to the HEAD request, that of course can be changed to a GET if you want.
You can use an anonymous function to pass the matches to your function:
$result = preg_replace_callback(
"/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
$result
);
Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e
would convert a double quote "
into \"
.
cell1.innerHTML="<?php echo $customerDESC; ?>";
cell2.innerHTML="<?php echo $comm; ?>";
cell3.innerHTML="<?php echo $expressFEE; ?>";
cell4.innerHTML="<?php echo $totao_unit_price; ?>";
it is working like a charm, the javascript is inside a php while loop
Java 8 way. Works for multiple parameters:
Stream.of(first, second, third).max(Integer::compareTo).get()
I think you just need to create your volume outside docker first with a docker create -v /location --name
and then reuse it.
And by the time I used to use docker a lot, it wasn't possible to use a static docker volume with dockerfile definition so my suggestion is to try the command line (eventually with a script ) .
Have a look at the "Jetty" web server Jetty. Superb piece of Open Source software that would seem to meet all your requirments.
If you insist on rolling your own then have a look at the "httpMessage" class.
You can use:
<script type="text/javascript">
function prepareFrame() {
var ifrm = document.createElement("iframe");
ifrm.setAttribute("src", "http://google.com/");
ifrm.style.width = "640px";
ifrm.style.height = "480px";
document.body.appendChild(ifrm);
}
</script>

June 17th, 2008
With a view to writing a jQuery UI integrated with the offline functionality of Google Gears i’ve been toying with some code to poll for network connection status using jQuery.
The basic premise is very simple. We create an instance of a network detection object which will poll a URL at regular intervals. Should these HTTP requests fail we can assume that network connectivity has been lost, or the server is simply unreachable at the current time.
$.networkDetection = function(url,interval){
var url = url;
var interval = interval;
online = false;
this.StartPolling = function(){
this.StopPolling();
this.timer = setInterval(poll, interval);
};
this.StopPolling = function(){
clearInterval(this.timer);
};
this.setPollInterval= function(i) {
interval = i;
};
this.getOnlineStatus = function(){
return online;
};
function poll() {
$.ajax({
type: "POST",
url: url,
dataType: "text",
error: function(){
online = false;
$(document).trigger('status.networkDetection',[false]);
},
success: function(){
online = true;
$(document).trigger('status.networkDetection',[true]);
}
});
};
};
You can view the demo here. Set your browser to work offline and see what happens…. no, it’s not very exciting.
What is exciting though (or at least what is exciting me) is the method by which the status gets relayed through the application. I’ve stumbled upon a largely un-discussed method of implementing a pub/sub system using jQuery’s trigger and bind methods.
The demo code is more obtuse than it need to be. The network detection object publishes ’status ‘events to the document which actively listens for them and in turn publishes ‘notify’ events to all subscribers (more on those later). The reasoning behind this is that in a real world application there would probably be some more logic controlling when and how the ‘notify’ events are published.
$(document).bind("status.networkDetection", function(e, status){
// subscribers can be namespaced with multiple classes
subscribers = $('.subscriber.networkDetection');
// publish notify.networkDetection even to subscribers
subscribers.trigger("notify.networkDetection", [status])
/*
other logic based on network connectivity could go here
use google gears offline storage etc
maybe trigger some other events
*/
});
Because of jQuery’s DOM centric approach events are published to (triggered on) DOM elements. This can be the window or document object for general events or you can generate a jQuery object using a selector. The approach i’ve taken with the demo is to create an almost namespaced approach to defining subscribers.
DOM elements which are to be subscribers are classed simply with “subscriber” and “networkDetection”. We can then publish events only to these elements (of which there is only one in the demo) by triggering a notify event on $(“.subscriber.networkDetection”)
The #notifier
div which is part of the .subscriber.networkDetection
group of subscribers then has an anonymous function bound to it, effectively acting as a listener.
$('#notifier').bind("notify.networkDetection",function(e, online){
// the following simply demonstrates
notifier = $(this);
if(online){
if (!notifier.hasClass("online")){
$(this)
.addClass("online")
.removeClass("offline")
.text("ONLINE");
}
}else{
if (!notifier.hasClass("offline")){
$(this)
.addClass("offline")
.removeClass("online")
.text("OFFLINE");
}
};
});
So, there you go. It’s all pretty verbose and my example isn’t at all exciting. It also doesn’t showcase anything interesting you could do with these methods, but if anyone’s at all interested to dig through the source feel free. All the code is inline in the head of the demo page

I can handle the title, full message, but the icon is always a default white circle:
Instead of my custom icon in the code (setSmallIcon or setSmallIcon) or default icon from the app:
Intent intent = new Intent(this, MainActivity.class);
// use System.currentTimeMillis() to have a unique ID for the pending intent
PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);
if (Build.VERSION.SDK_INT < 16) {
Notification n = new Notification.Builder(this)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pIntent)
.setAutoCancel(true).getNotification();
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//notificationManager.notify(0, n);
notificationManager.notify(id, n);
} else {
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Notification n = new Notification.Builder(this)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setLargeIcon(bm)
.setContentIntent(pIntent)
.setAutoCancel(true).build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//notificationManager.notify(0, n);
notificationManager.notify(id, n);
}
If you are already using Newtonsoft.Json try this:
// Alternative using WebApi.Client 5.2.7
////var response = await Client.PutAsJsonAsync(
//// "api/AgentCollection", user
//// requestListDto)
var response = await Client.PostAsync("api/AgentCollection", new StringContent(
JsonConvert.SerializeObject(user), Encoding.UTF8, "application/json"));
Performance are better than JavaScriptSerializer. Take a look here https://www.newtonsoft.com/json/help/html/Introduction.htm
I had exact same error after adding a new configuration via ConfigurationManager in Visual Studio.
It turned out when the 'Production' configuration was added for the whole solution (and each project) the OutputPath element was not added to the .csproj files.
To fix, I went to the Build tab in project properties, changed OutputPath from \bin\Production\
to \bin\Production
(deleted trailing \
) and saved changes. This forced creation of the OutputPath element in the .csproj file and the project has built successfully.
Sounds like a glitch to me.

This is how a browser interprets and empty href. It assumes you want to link back to the page that you are on. This is the same as if you dont assign an action to a <form>
element.
If you add any word in the href it will append it to the current page unless you:
/
to the front of it telling it to append it to your base url e.g. http://www.whatever.com/something
#
sign in which case it is an in-page anchorEDIT: It was suggested that I add a link to help clarify the situation. I found the following site that I think does a really good job explaining the href
attribute of anchor tags and how it interprets URL paths. It is not incredibly technical and very human-readable. It uses lots of examples to illustrate the differences between the path types: http://www.mediacollege.com/internet/html/hyperlinks.html
For JPA 2.1 the javax.persistence package can be found in here:
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.1-api</artifactId>
<version>1.0.0.Final</version>
</dependency>
See: hibernate-jpa-2.1-api on Maven Central The pattern seems to be to change the artefact name as the JPA version changes. If this continues new versions can be expected to arrive in Maven Central here: Hibernate JPA versions
The above JPA 2.1 APi can be used in conjunction with Hibernate 4.3.7, specifically:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.3.7.Final</version>
</dependency>

Most of the answers above should suffice you but if you are doing a lot more of such predicate and complex combinations check out Squeel. You will be able to doing something like:
Topic.where{{forum_id.not_in => @forums.map(&:id)}}
Topic.where{forum_id.not_in @forums.map(&:id)}
Topic.where{forum_id << @forums.map(&:id)}
UPDATE git 1.8.3 introduced a more efficient way to get a rough size:
git count-objects -vH
(see answer by @VonC)
For different ideas of "complete size" you could use:
git bundle create tmp.bundle --all
du -sh tmp.bundle
Close (but not exact:)
git gc
du -sh .git/
With the latter, you would also be counting:
ymin, ymax = axes.get_ylim()
If you are using the plt
api directly, you can avoid calls to axes
altogether:
def myplotfunction(title, values, errors, plot_file_name):
# plot errorbars
indices = range(0, len(values))
fig = plt.figure()
plt.errorbar(tuple(indices), tuple(values), tuple(errors), marker='.')
plt.ylim([-0.5, len(values) - 0.5])
plt.xlabel('My x-axis title')
plt.ylabel('My y-axis title')
# title
plt.title(title)
# save as file
plt.savefig(plot_file_name)
# close figure
plt.close(fig)
I used SQL Server Profiler (available in SSMS => Tools menu) and saw there (when IIS attempted to connect to database) that my IIS user was for some reason NT AUTHORITY\IUSR, no matter of all steps recommended in answers in this question. So I added that user to SQL Server, and it worked...
You can use the document compatibility mode to do this, which is what you were trying.. However, thing to note is: It must appear in the Web page's header (the HEAD section) before all other elements, except for the title element and other meta elements Hope that was the issue.. Also, The X-UA-compatible header is not case sensitive Refer: http://msdn.microsoft.com/en-us/library/cc288325%28v=vs.85%29.aspx#SetMode
Edit: in case something happens to kill the msdn link, here is the content:
Specifying Document Compatibility Modes
You can use document modes to control the way Internet Explorer interprets and displays your webpage. To specify a specific document mode for your webpage, use the meta element to include an X-UA-Compatible header in your webpage, as shown in the following example.
<html> <head> <!-- Enable IE9 Standards mode --> <meta http-equiv="X-UA-Compatible" content="IE=9" > <title>My webpage</title> </head> <body> <p>Content goes here.</p> </body> </html>
If you view this webpage in Internet Explorer 9, it will be displayed in IE9 mode.
The following example specifies EmulateIE7 mode.
<html> <head> <!-- Mimic Internet Explorer 7 --> <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" > <title>My webpage</title> </head> <body> <p>Content goes here.</p> </body> </html>
In this example, the X-UA-Compatible header directs Internet Explorer to mimic the behavior of Internet Explorer 7 when determining how to display the webpage. This means that Internet Explorer will use the directive (or lack thereof) to choose the appropriate document type. Because this page does not contain a directive, the example would be displayed in IE5 (Quirks) mode.
title = u"Klüft skräms inför på fédéral électoral große"
import unicodedata
unicodedata.normalize('NFKD', title).encode('ascii', 'ignore')
'Kluft skrams infor pa federal electoral groe'
You don't need to escape it inside. You can use the |
character to delimit searches.
"\"foo\"\'bar\'".replace(/("|')/g, "")
There might be a better way but here is what I have done in the past and it works quite well:
items = data.items() #Gets all the data from this Bunch - a huge list
mydata = pd.DataFrame(items[1][1]) #Gets the Attributes
mydata[len(mydata.columns)] = items[2][1] #Adds a column for the Target Variable
mydata.columns = items[-1][1] + [items[2][0]] #Gets the column names and updates the dataframe
Now mydata will have everything you need - attributes, target variable and columnnames
I solved it easily via running these codes:
npm uninstall mongodb --save
npm install [email protected] --save
Happy Coding!
Update:
As of jQuery 1.6+ you should use prop()
instead of attr()
in this case.
The difference between attributes and properties can be important in specific situations. Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.
var theValue = "whatever";
$("#selectID").val( theValue ).prop('selected',true);
Original Answer:
If you want to select by the value of the option, REGARDLESS of its position (this example assumes you have an ID for your select):
var theValue = "whatever";
$("#selectID").val( theValue ).attr('selected',true);
You do not need to "unselect". That happens automatically when you select another.
You have to use eval() to execute any script code that you've inserted as DOM text.
MooTools will do this for you automatically, and I'm sure jQuery would as well (depending on the version. jQuery version 1.6+ uses eval
). This saves a lot of hassle of parsing out <script>
tags and escaping your content, as well as a bunch of other "gotchas".
Generally if you're going to eval()
it yourself, you want to create/send the script code without any HTML markup such as <script>
, as these will not eval()
properly.
You need to just replace '
with ''
inside your string
SELECT colA, colB, colC
FROM tableD
WHERE colA = 'John''s Mobile'
You can also use REPLACE(@name, '''', '''''')
if generating the SQL dynamically
If you want to escape inside a like statement then you need to use the ESCAPE syntax
It's also worth mentioning that you're leaving yourself open to SQL injection attacks if you don't consider it. More info at Google or: http://it.toolbox.com/wiki/index.php/How_do_I_escape_single_quotes_in_SQL_queries%3F
This is one of the outright idiocies of CSS - I have yet to understand the reasoning (if someone knows, pls. explain).
100% means 100% of the container height - to which any margins, borders and padding are added. So it is effectively impossible to get a container which fills it's parent and which has a margin, border, or padding.
Note also, setting height is notoriously inconsistent between browsers, too.
Another thing I've learned since I posted this is that the percentage is relative the container's length, that is, it's width, making a percentage even more worthless for height.
Nowadays, the vh and vw viewport units are more useful, but still not especially useful for anything other than the top-level containers.
I created it in a more similar way to the SQL, I think it is easier to understand
var list = (from a in listA.AsEnumerable()
join b in listB.AsEnumerable() on a.id equals b.id into ab
from c in ab.DefaultIfEmpty()
where c != null
select new { id = c.id, name = c.nome }).ToList();
You can also set DirectoryIndex in apache's httpd.conf file.
CentOS keeps this file in /etc/httpd/conf/httpd.conf
Debian: /etc/apache2/apache2.conf
Open the file in your text editor and find the line starting with DirectoryIndex
To load landing.html as a default (but index.html if that's not found) change this line to read:
DirectoryIndex landing.html index.html
fill in the "X display location" did not work for me. but install MobaXterm did the job.
In my case, the problem was caused by not being logged in with Postman, so I opened a connection in another tab with a session cookie I took from the headers in my Chrome session.
Similar to yebmouxing I could not the
xhr.getResponseHeader('Set-Cookie');
method to work. It would only return null even if I had set HTTPOnly to false on my server.
I too wrote a simple js helper function to grab the cookies from the document. This function is very basic and only works if you know the additional info (lifespan, domain, path, etc. etc.) to add yourself:
function getCookie(cookieName){
var cookieArray = document.cookie.split(';');
for(var i=0; i<cookieArray.length; i++){
var cookie = cookieArray[i];
while (cookie.charAt(0)==' '){
cookie = cookie.substring(1);
}
cookieHalves = cookie.split('=');
if(cookieHalves[0]== cookieName){
return cookieHalves[1];
}
}
return "";
}
The accepted answer doesn't cover text nodes (undefined is printed out).
This code snippet solves it:

else if (element.nodeType === Node.TEXT_NODE) {_x000D_

For questions like this, it is always worth taking a look in the manual first. Date and time functions in the mySQL manual
CURDATE()
returns the DATE part of the current time. Manual on CURDATE()
NOW()
returns the date and time portions as a timestamp in various formats, depending on how it was requested. Manual on NOW().
With support library v25.0.0 there finally is a default implementation of basic horizontal and vertical dividers available!
https://developer.android.com/reference/android/support/v7/widget/DividerItemDecoration.html
V8 is an implementation of JavaScript. It lets you run standalone JavaScript applications (among other things).
Node.js is simply a library written for V8 which does evented I/O. This concept is a bit trickier to explain, and I'm sure someone will answer with a better explanation than I... The gist is that rather than doing some input or output and waiting for it to happen, you just don't wait for it to finish. So for example, ask for the last edited time of a file:
// Pseudo code
stat( 'somefile' )
That might take a couple of milliseconds, or it might take seconds. With evented I/O you simply fire off the request and instead of waiting around you attach a callback that gets run when the request finishes:
// Pseudo code
stat( 'somefile', function( result ) {
// Use the result here
} );
// ...more code here
This makes it a lot like JavaScript code in the browser (for example, with Ajax style functionality).
For more information, you should check out the article Node.js is genuinely exciting which was my introduction to the library/platform... I found it quite good.
With New-Item you can add the Force parameter
New-Item -Force -ItemType directory -Path foo
Or the ErrorAction parameter
New-Item -ErrorAction Ignore -ItemType directory -Path foo
If you are at a certain branch mybranch
, just go ahead and git checkout commit_hash
. Then you can return to your branch by git checkout mybranch
. I had the same game bisecting a bug today :) Also, you should know about git bisect.
If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web
tab. Under the Servers
section you can configure the URL. There is also a button to create the virtual directory.
You can just go for String
replace method.-
line1 = line1.replace("\"", "");
If method1()
and method2()
both will be called by two or many threads, there is a good chance of deadlock because if thread 1 acquires lock on String object while executing method1()
and thread 2 acquires lock on Integer object while executing method2()
both will be waiting for each other to release lock on Integer and String to proceed further, which will never happen.
public void method1() {
synchronized (String.class) {
System.out.println("Acquired lock on String.class object");
synchronized (Integer.class) {
System.out.println("Acquired lock on Integer.class object");
}
}
}
public void method2() {
synchronized (Integer.class) {
System.out.println("Acquired lock on Integer.class object");
synchronized (String.class) {
System.out.println("Acquired lock on String.class object");
}
}
}
Even though CMD is written down in the Dockerfile, it really is runtime information. Just like EXPOSE, but contrary to e.g. RUN and ADD. By this, I mean that you can override it later, in an extending Dockerfile, or simple in your run command, which is what you are experiencing. At all times, there can be only one CMD.
If you want to run multiple services, I indeed would use supervisor. You can make a supervisor configuration file for each service, ADD these in a directory, and run the supervisor with supervisord -c /etc/supervisor
to point to a supervisor configuration file which loads all your services and looks like
[supervisord]
nodaemon=true
[include]
files = /etc/supervisor/conf.d/*.conf
If you would like more details, I wrote a blog on this subject here: http://blog.trifork.com/2014/03/11/using-supervisor-with-docker-to-manage-processes-supporting-image-inheritance/
Recently I was playing with this method too. I wrote a memoized algorithm to calcualte Fibonacci numbers which could serve as another illustration on how to use the method.
We can start by defining a map and putting the values in it for the base cases, namely, fibonnaci(0)
and fibonacci(1)
:
private static Map<Integer,Long> memo = new HashMap<>();
static {
memo.put(0,0L); //fibonacci(0)
memo.put(1,1L); //fibonacci(1)
}
And for the inductive step all we have to do is redefine our Fibonacci function as follows:
public static long fibonacci(int x) {
return memo.computeIfAbsent(x, n -> fibonacci(n-2) + fibonacci(n-1));
}
As you can see, the method computeIfAbsent
will use the provided lambda expression to calculate the Fibonacci number when the number is not present in the map. This represents a significant improvement over the traditional, tree recursive algorithm.

React.version
is what you are looking for.
It is undocumented though (as far as I know) so it may not be a stable feature (i.e. though unlikely, it may disappear or change in future releases).
Example with React
imported as a script
const REACT_VERSION = React.version;
ReactDOM.render(
<div>React version: {REACT_VERSION}</div>,
document.getElementById('root')
);
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<div id="root"></div>
_x000D_
Example with React
imported as a module
import React from 'react';
console.log(React.version);
Obviously, if you import React
as a module, it won't be in the global scope. The above code is intended to be bundled with the rest of your app, e.g. using webpack. It will virtually never work if used in a browser's console (it is using bare imports).
This second approach is the recommended one. Most websites will use it. create-react-app does this (it's using webpack behind the scene). In this case, React
is encapsulated and is generally not accessible at all outside the bundle (e.g. in a browser's console).
In OpenSuse at least, the unrpm
command comes with the build
package.
In a suitable directory (because this is an archive bomb):
unrpm file.rpm
Try this:
public static String[] vratAtributy() {
String[] atributy = new String[values().length];
for(int index = 0; index < atributy.length; index++) {
atributy[index] = values()[index].toString();
}
return atributy;

private static final String hostExtractorRegexString = "(?:https?://)?(?:www\\.)?(.+\\.)(com|au\\.uk|co\\.in|be|in|uk|org\\.in|org|net|edu|gov|mil)";
private static final Pattern hostExtractorRegexPattern = Pattern.compile(hostExtractorRegexString);
public static String getDomainName(String url){
if (url == null) return null;
url = url.trim();
Matcher m = hostExtractorRegexPattern.matcher(url);
if(m.find() && m.groupCount() == 2) {
return m.group(1) + m.group(2);
}
return null;
}
Explanation : The regex has 4 groups. The first two are non-matching groups and the next two are matching groups.
The first non-matching group is "http" or "https" or ""
The second non-matching group is "www." or ""
The second matching group is the top level domain
The first matching group is anything after the non-matching groups and anything before the top level domain
The concatenation of the two matching groups will give us the domain/host name.
PS : Note that you can add any number of supported domains to the regex.
Similarly, if you wanted to redirect to a sub-folder instead of a sub-domain, do the following:

I know it's not a direct answer to the question, but somebody (like me) might stumble upon this question and wonder how that method would be accomplished as well.
Use git rev-parse --git-dir
if git rev-parse --git-dir > /dev/null 2>&1; then : # This is a valid git repository (but the current working # directory may not be the top level. # Check the output of the git rev-parse command if you care) else : # this is not a git repository fi
All the answers here I found to be un-neccesarily complex for a simple problem (at least to an experienced java developer, which I am not). I had a similar problem and chanced upon this (and other) solutions, and though they provided a pointer, for a beginner I found as stated above. My solution, depends on where in the the Object your Date is, in this case, the date is the first element of the Object[] where dataVector is the ArrayList containing your Objects.
Collections.sort(dataVector, new Comparator<Object[]>() {
public int compare(Object[] o1, Object[] o2) {
return ((Date)o1[0]).compareTo(((Date)o2[0]));
}
});
Use ALTER SESSION statements to set comparison to case-insensitive:
alter session set NLS_COMP=LINGUISTIC;
alter session set NLS_SORT=BINARY_CI;
If you're still using version 10gR2, use the below statements. See this FAQ for details.
alter session set NLS_COMP=ANSI;
alter session set NLS_SORT=BINARY_CI;
Just connect the device to the PC with a USB cable, then copy the .apk file to the device. On the device, touch the APK file in the file explorer to install it.
You could also offer the .apk on your website. People can download it, then touch it to install.

I am using Jackson 1.9.7 and I found that doing the following does not solve my serialization/deserialization timezone issue:
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
dateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
objectMapper.setDateFormat(dateFormat);
Instead of "2014-02-13T20:09:09.859Z" I get "2014-02-13T08:09:09.859+0000" in the JSON message which is obviously incorrect. I don't have time to step through the Jackson library source code to figure out why this occurs, however I found that if I just specify the Jackson provided ISO8601DateFormat
class to the ObjectMapper.setDateFormat
method the date is correct.
Except this doesn't put the milliseconds in the format which is what I want so I sub-classed the ISO8601DateFormat
class and overrode the format(Date date, StringBuffer toAppendTo, FieldPosition fieldPosition)
method.
/**
* Provides a ISO8601 date format implementation that includes milliseconds
*
*/
public class ISO8601DateFormatWithMillis extends ISO8601DateFormat {
/**
* For serialization
*/
private static final long serialVersionUID = 2672976499021731672L;
@Override
public StringBuffer format(Date date, StringBuffer toAppendTo, FieldPosition fieldPosition)
{
String value = ISO8601Utils.format(date, true);
toAppendTo.append(value);
return toAppendTo;
}
}
This issue I was solved by giving right permission of the folder as well as check from IIS.
I was given permission to everyone as I am testing in my local environment. But in publish mode I think we give only permission to ASP.Net user.
MySQL will run in Read-Only mode when you fetch by joining two tables and columns from two tables are included in the result. Then you can't update the values directly.
You have to either create a language file and then set it using :
"oLanguage": {
"sUrl": "media/language/your_file.txt"
}
Im not sure what server language you are using but something like this would work in PHP :
"oLanguage": {
"sUrl": "media/language/custom_lang_<?php echo $language ?>.txt"
}
Where language
matches the file name for a specific language.
or change individual settings :
"oLanguage": {
"sLengthMenu": "Display _MENU_ records per page",
"sZeroRecords": "Nothing found - sorry",
"sInfo": "Showing _START_ to _END_ of _TOTAL_ records",
"sInfoEmpty": "Showing 0 to 0 of 0 records",
"sInfoFiltered": "(filtered from _MAX_ total records)"
}

Import the entire JQuery's contents in the Global scope. This inserts $ into the current scope, containing all the exported bindings from the JQuery.
import * as $ from 'jquery';
Now the $ belongs to the window object.
If you inherit publicly from another class, everybody knows you are inheriting and you can be used polymorphically by anyone through a base class pointer.
If you inherit protectedly only your children classes will be able to use you polymorphically.
If you inherit privately only yourself will be able to execute parent class methods.
Which basically symbolizes the knowledge the rest of the classes have about your relationship with your parent class
Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

As others have indicated, the overlay icon registry area is congested. Here is a powershell script that allows you to dump all the overlays in the registry to a file, then after you edit the file to prioritize your overlays the way you want, you can import them back in and protect them against further modifications from other programs running under SYSTEM.
As stated in other posts, you can use the break keyword. One thing that was hinted at but not explained is that the keyword can take a numeric value to tell PHP how many levels to break from.
For example, if you have three foreach loops nested in each other trying to find a piece of information, you could do 'break 3' to get out of all three nested loops. This will work for the 'for', 'foreach', 'while', 'do-while', or 'switch' structures.
$person = "Rasmus Lerdorf";
$found = false;
foreach($organization as $oKey=>$department)
{
foreach($department as $dKey=>$group)
{
foreach($group as $gKey=>$employee)
{
if ($employee['fullname'] == $person)
{
$found = true;
break 3;
}
} // group
} // department
} // organization
The pedantic answer (though not necessarily the most useful one, depending on what you want to do with the result) is:
string.length() * 2
Java strings are physically stored in UTF-16BE
encoding, which uses 2 bytes per code unit, and String.length()
measures the length in UTF-16 code units, so this is equivalent to:
final byte[] utf16Bytes= string.getBytes("UTF-16BE");
System.out.println(utf16Bytes.length);
And this will tell you the size of the internal char
array, in bytes.
Note: "UTF-16"
will give a different result from "UTF-16BE"
as the former encoding will insert a BOM, adding 2 bytes to the length of the array.
This isn't an answer. I just want to show that IF NOT EXISTS(...) INSERT
method isn't safe. You have to execute first Session #1
and then Session #2
. After v #2
you will see that without an UNIQUE
index you could get duplicate pairs (SoftwareName,SoftwareSystemType)
. Delay from session #1 is used to give you enough time to execute the second script (session #2). You could reduce this delay.

make clean
generally only cleans built files in the directory containing the source code itself, and rarely touches any installed software.
Makefiles generally don't contain a target for uninstallation -- you usually have to do that yourself, by removing the files from the directory into which they were installed. For example, if you built a program and installed it (using make install
) into /usr/local
, you'd want to look through /usr/local/bin
, /usr/local/libexec
, /usr/local/share/man
, etc., and remove the unwanted files. Sometimes a Makefile includes an uninstall
target, but not always.
Of course, typically on a Linux system you install software using a package manager, which is capable of uninstalling software "automagically".
Yes you can convert it back. You can try:
date("Y-m-d H:i:s", 1388516401);
The logic behind this conversion from date to an integer is explained in strtotime in PHP:
The function expects to be given a string containing an English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.
For example, strtotime("1970-01-01 00:00:00")
gives you 0 and strtotime("1970-01-01 00:00:01")
gives you 1.
This means that if you are printing strtotime("2014-01-01 00:00:01")
which will give you output 1388516401
, so the date 2014-01-01 00:00:01
is 1,388,516,401 seconds after January 1 1970 00:00:00 UTC.
You can also use the shorter format
From the man page:
%F full date; same as %Y-%m-%d
Example:
#!/bin/bash
date_today=$(date +%F)
date_dir=$(date +%F -d yesterday)
The X-Powered-By header is added by IIS to the HTTP response, so you can remove it even on server level via IIS Manager:
You can use the web.config directly:
<system.webServer>
<httpProtocol>
<customHeaders>
<remove name="X-Powered-By" />
</customHeaders>
</httpProtocol>
</system.webServer>
This happened to me when I installed Intellij IDEA 2017, go to menu Preferences -> Build, Execution, Deployment -> Debugger and disable the option: "Force Classic VM for JDK 1.3.x and earlier". This works to me.
Do you mean like this
int index = 2;
string s = "hello";
Console.WriteLine(s[index]);
string also implements IEnumberable<char>
so you can also enumerate it like this
foreach (char c in s)
Console.WriteLine(c);
Think of it as the difference between a requirement and a suggestion. For the select
element, the user is required to select one of the options you've given. For the datalist
element, it is suggested that the user select one of the options you've given, but he can actually enter anything he wants in the input.
Edit 1: So which one you use depends upon your requirements. If the user must enter one of your choices, use the select
element. If the use can enter whatever, use the datalist
element.
Edit 2: Found this tidbit in the HTML Living Standard: "Each option element that is a descendant of the datalist element...represents a suggestion."

I was getting this error while using JQuery 1.10 and JQuery UI 1.8. I was able to resolve this error by updating to the latest JQuery UI 1.11.4.
I had a problem similar to yours. I wanted my links to get bold when you hover over them but not only in the menu but also in the text. As you cen guess it would be a real chore figuring out all the different widths. The solution is pretty simple:
Create a box that contains the link text in bold but coloured like your background and but your real link above it. Here's an example from my page:
CSS:
.hypo { font-weight: bold; color: #FFFFE0; position: static; z-index: 0; }
.hyper { position: absolute; z-index: 1; }
Of course you need to replace #FFFFE0 by the background colour of your page. The z-indices don't seem to be necessary but I put them anyway (as the "hypo" element will occur after the "hyper" element in the HTML-Code). Now, to put a link on your page, include the following:
HTML:
You can find foo <a href="http://bar.com" class="hyper">here</a><span class="hypo">here</span>
The second "here" will be invisible and hidden below your link. As this is a static box with your link text in bold, the rest of your text won't shift any longer as it is already shifted before you hover over the link.
Hope I was able to help :).

assertNotNull

Put the text file in the assets directory. If there isnt an assets dir create one in the root of the project. Then you can use Context.getAssets().open("BlockForTest.txt");
to open a stream to this file.
One thing you have to watch out for is the fairly severe differences in the way SQL Server and MySQL implement the SQL syntax.
Here's a nice Comparison of Different SQL Implementations.
For example, take a look at the top-n section. In MySQL:
SELECT age
FROM person
ORDER BY age ASC
LIMIT 1 OFFSET 2
In SQL Server (T-SQL):
SELECT TOP 3 WITH TIES *
FROM person
ORDER BY age ASC
You can simply write a if condition inside server {} block:
server {
if ($host = mydomain.com) {
return 301 http://www.adifferentdomain.com;
}
}
If you are getting the following error while connecting the mysql (either local or mysql container running the mysql):
java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed
Solution: Add the following line in your database service:
command: --default-authentication-plugin=mysql_native_password
For formatting the price in another currency than the current one:
Mage::app()->getLocale()->currency('EUR')->toCurrency($price);
With Calendar it works as follows:
//create first Calendar object
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 15); // 3 PM
// the same is
calendar.set(Calendar.AM_PM, Calendar.PM); // choose PM mode
calendar.set(Calendar.HOUR, 3); // 3 PM
System.out.println( calendar.get(Calendar.HOUR) ); // AM_PM format
System.out.println( calendar.get(Calendar.HOUR_OF_DAY) ); // 0-23 format
Another option is to update the Microsoft.AspnNet.Mvc NuGet package. Be careful, because NuGet update does not update the Web.Config. You should update all previous version numbers to updated number. For example if you update from asp.net MVC 4.0.0.0 to 5.0.0.0, then this should be replaced in the Web.Config:
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

You might want to look into open2 and open3 in case you need bidirectional communication.
I have found the answer to my question.
client.DefaultRequestHeaders.Add("X-Version","1");
That should add a custom header to your request
The problem is that you can't use a list
as the key in a dict
, since dict
keys need to be immutable. Use a tuple instead.
This is a list:
[x, y]
This is a tuple:
(x, y)
Note that in most cases, the (
and )
are optional, since ,
is what actually defines a tuple (as long as it's not surrounded by []
or {}
, or used as a function argument).
You might find the section on tuples in the Python tutorial useful:
Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.
And in the section on dictionaries:
Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().
In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

This will load all links on the page in the parent window. If you want your links to load in a new window, use:
<base target="_blank">
One main difference is the Local
part of LocalDateTime
. If you live in Germany and create a LocalDateTime
instance and someone else lives in USA and creates another instance at the very same moment (provided the clocks are properly set) - the value of those objects would actually be different. This does not apply to Instant
, which is calculated independently from time zone.
LocalDateTime
stores date and time without timezone, but it's initial value is timezone dependent. Instant
's is not.
Moreover, LocalDateTime
provides methods for manipulating date components like days, hours, months. An Instant
does not.
apart from the nanosecond precision advantage of Instant and the time-zone part of LocalDateTime
Both classes have the same precision. LocalDateTime
does not store timezone. Read javadocs thoroughly, because you may make a big mistake with such invalid assumptions: Instant and LocalDateTime.
I had node 15.x.x
, and "node-sass": "^4.11.0"
.
I saw in the release notes from node-sass
and saw the node higest version compatible with node-sass 4.11.0 was 11, so I uninstalled node and reinstall 11.15.0 version (I'm working with Windows).
Check node-sass releases.
(this is what you should see in the node-sass releases.)
Hope that helps and sorry for my english :)
Something very similar can be seen on http://goo.gl when you shorten the URL.
There is a readonly input element that gets programmatically focused, with tooltip press CTRL-C to copy.
When you hit that shortcut, the input content effectively gets into the clipboard. Really nice :)
You can try like below with sqljdbc4-2.0.jar:
public void getConnection() throws ClassNotFoundException, SQLException, IllegalAccessException, InstantiationException {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
String url = "jdbc:sqlserver://<SERVER_IP>:<PORT_NO>;databaseName=" + DATABASE_NAME;
Connection conn = DriverManager.getConnection(url, USERNAME, PASSWORD);
System.out.println("DB Connection started");
Statement sta = conn.createStatement();
String Sql = "select * from TABLE_NAME";
ResultSet rs = sta.executeQuery(Sql);
while (rs.next()) {
System.out.println(rs.getString("COLUMN_NAME"));
}
}
In reference to @stanley's comment -
Don't try and use tap gestures to row selections to work in UITableView

To open a workbook. Use xlapp.workbooks.Open()

Next make sure you use the property Value2 when assigning a value to the cell using either the cells property or the range object.
Try the maven-exec-plugin. From there:
mvn exec:java -Dexec.mainClass="com.example.Main"
This will run your class in the JVM. You can use -Dexec.args="arg0 arg1"
to pass arguments.
If you're on Windows, apply quotes for
exec.mainClass
andexec.args
:mvn exec:java -D"exec.mainClass"="com.example.Main"
If you're doing this regularly, you can add the parameters into the pom.xml as well:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<goals>
<goal>java</goal>

<configuration>
<mainClass>com.example.Main</mainClass>
<arguments>
<argument>foo</argument>
<argument>bar</argument>
</arguments>

In your case you can do that without using push
at all:
var myArray = [
[1,1,1,1,1],
[1,1,1,1,1],
[1,1,1,1,1]
]
var newRows = 8;
var newCols = 7;
var item;
for (var i = 0; i < newRows; i++) {
item = myArray[i] || (myArray[i] = []);
for (var k = item.length; k < newCols; k++)
item[k] = 0;
}

Here is an Alternative that worked for me:
yourFrame.setIconImage(Toolkit.getDefaultToolkit().getImage(getClass().getResource(Filepath)));
It's very similar to the accepted Answer.
For me, it worked best to add this in image css: max-width:100%;
and NOT specify image width and height in html parameters. This adjusted the width to fit in device screen while adjusting height automatically. Otherwise height might be distorted.
I know it is late but I just want to share on what I have done for this. I'm not allowed to add another table or trigger so I need to generate it in a single query upon insert. For your case, can you try this query.
CREATE TABLE YOURTABLE(
IDNUMBER VARCHAR(7) NOT NULL PRIMARY KEY,
ENAME VARCHAR(30) not null
);
Perform a select and use this select query and save to the parameter @IDNUMBER
(SELECT IFNULL
(CONCAT('LHPL',LPAD(
(SUBSTRING_INDEX
(MAX(`IDNUMBER`), 'LHPL',-1) + 1), 5, '0')), 'LHPL001')
AS 'IDNUMBER' FROM YOURTABLE ORDER BY `IDNUMBER` ASC)
And then Insert query will be :
INSERT INTO YOURTABLE(IDNUMBER, ENAME) VALUES
(@IDNUMBER, 'EMPLOYEE NAME');
The result will be the same as the other answer but the difference is, you will not need to create another table or trigger. I hope that I can help someone that have a same case as mine.
@Masci is correct, but in case you're using C (and the gcc

Took me a bit to figure out...

- I assume that this can't be the case as if it was you'd get an exception in your while loop and nothing would be output.resultset.getString(i++)
will get columns 1,2,3 and so on from each subsequent row.I think that the second point is probably your problem here.
Lets say you only had 1 row returned, as follows:
Col 1, Col 2, Col 3
A , B, C
Your code as it stands would only get A - it wouldn't get the rest of the columns.
I suggest you change your code as follows:
ResultSet resultset = ...;
ArrayList<String> arrayList = new ArrayList<String>();
while (resultset.next()) {
int i = 1;
while(i <= numberOfColumns) {
arrayList.add(resultset.getString(i++));
}
System.out.println(resultset.getString("Col 1"));
System.out.println(resultset.getString("Col 2"));
System.out.println(resultset.getString("Col 3"));
System.out.println(resultset.getString("Col n"));
}
Edit:
To get the number of columns:
ResultSetMetaData metadata = resultset.getMetaData();
int numberOfColumns = metadata.getColumnCount();
You can use IPython.display.clear_output
to clear the output of a cell.
from IPython.display import clear_output
for i in range(10):
clear_output(wait=True)
print("Hello World!")
At the end of this loop you will only see one Hello World!
.
Without a code example it's not easy to give you working code. Probably buffering the latest n events is a good strategy. Whenever the buffer changes you can clear the cell's output and print the buffer again.
There are two options. Ayman's approach is the most simple, but I would add one extra note to it. You should really cache jQuery selections, there is no reason to call $("#input-field-id")
twice:
var input = $( "#input-field-id" );
input.val( input.val() + "more text" );
The other option, .val()
can also take a function as an argument. This has the advantange of easily working on multiple inputs:
$( "input" ).val( function( index, val ) {
return val + "more text";
});
Use _.map
instead of _.pluck
. In the latest version the _.pluck
has been removed.
If you are using Constraint Layout, you can set any view inside it, to fill a percentage of the screen with:
layout_constraintWidth_percent="0.8"
So, for example, if you have a ScrollView inside the dialog and you want to set it to a percentage of the screen height. It would be like this:
<ScrollView
android:id="@+id/scrollView"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintHeight_percent="0.8">
Hope it helps someone !!
To move a file you could also use Jakarta Commons IOs FileUtils.moveFile
On error it throws an IOException
, so when no exception is thrown you know that that the file was moved.
You will get this error when you call any of the setXxx()
methods on PreparedStatement
, while the SQL query string does not have any placeholders ?
for this.
For example this is wrong:
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES (val1, val2, val3)";
// ...
preparedStatement = connection.prepareStatement(sql);
preparedStatement.setString(1, val1); // Fail.
preparedStatement.setString(2, val2);
preparedStatement.setString(3, val3);
You need to fix the SQL query string accordingly to specify the placeholders.
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES (?, ?, ?)";
// ...
preparedStatement = connection.prepareStatement(sql);
preparedStatement.setString(1, val1);
preparedStatement.setString(2, val2);
preparedStatement.setString(3, val3);
Note the parameter index starts with 1
and that you do not need to quote those placeholders like so:
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES ('?', '?', '?')";
Otherwise you will still get the same exception, because the SQL parser will then interpret them as the actual string values and thus can't find the placeholders anymore.
You must use an integer value for the CURLOPT_SSLVERSION
value, not a string as listed above
Try this:
curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 6); //Integer NOT string TLS v1.2
http://php.net/manual/en/function.curl-setopt.php
value should be an integer for the following values of the option parameter:
CURLOPT_SSLVERSION
One of
CURL_SSLVERSION_DEFAULT (0)
CURL_SSLVERSION_TLSv1 (1)
CURL_SSLVERSION_SSLv2 (2)
CURL_SSLVERSION_SSLv3 (3)
CURL_SSLVERSION_TLSv1_0 (4)
CURL_SSLVERSION_TLSv1_1 (5)
CURL_SSLVERSION_TLSv1_2 (6).
Here is a good explanation of your problem with the solution.
SetUp your HADOOP_HOME environment variable on the OS level or programmatically:
System.setProperty("hadoop.home.dir", "full path to the folder with winutils");
Enjoy
You can do it programmatically:
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdlib.h>
int main() {
int fd = creat("/tmp/foo.txt", 0644);
ftruncate(fd, SIZE_IN_BYTES);
close(fd);
return 0;
}
This approach is especially useful to subsequently mmap the file into memory.
use the following command to check that the file has the correct size:
# du -B1 --apparent-size /tmp/foo.txt
Be careful:
# du /tmp/foo.txt
will probably print 0 because it is allocated as Sparse file if supported by your filesystem.

Or about the best module I have found http://pypi.python.org/pypi/colorama
From http://www.w3.org/International/articles/language-tags/
"Language tag syntax is defined by the IETF's BCP 47. BCP stands for 'Best Current Practice', and is a persistent name for a series of RFCs whose numbers change as they are updated. The latest RFC describing language tag syntax is RFC 5646, Tags for the Identification of Languages, and it obsoletes the older RFCs 4646, 3066 and 1766.
You used to find subtags by consulting the lists of codes in various ISO standards, but now you can find all subtags in the IANA Language Subtag Registry."
AFAIK most locale-aware applications (that are written by professionals) abide by this standard. It isn't just something somebody threw together and that different people interpret differently.
I'd strongly suggest you investigate the internationalization features of your particular development language, as you'll probably end up reinventing the wheel if you don't.

Use butterknife to bind the drawable resource to a variable by adding this to the top of your class (before any methods).
@Bind(R.id.some_layout)
RelativeLayout layout;
@BindDrawable(R.drawable.some_drawable)
Drawable background;
then inside one of your methods add
layout.setBackground(background);
That's all you need
The order of a dictionary doesn't have any relationship to the order it was defined in. This is true of all dictionaries, not just those turned into JSON.
>>> {"b": 1, "a": 2}
{'a': 2, 'b': 1}
Indeed, the dictionary was turned "upside down" before it even reached json.dumps
:
>>> {"id":1,"name":"David","timezone":3}
{'timezone': 3, 'id': 1, 'name': 'David'}
For TS 3.9.x

The currently accepted answer does not actually address the question, which asks how to save lists that contain both strings and float numbers. For completeness I provide a fully working example, which is based, with some modifications, on the link given in @joris comment.
import numpy as np
names = np.array(['NAME_1', 'NAME_2', 'NAME_3'])
floats = np.array([ 0.1234 , 0.5678 , 0.9123 ])
ab = np.zeros(names.size, dtype=[('var1', 'U6'), ('var2', float)])
ab['var1'] = names
ab['var2'] = floats
np.savetxt('test.txt', ab, fmt="%10s %10.3f")
Update: This example also works properly in Python 3 by using the 'U6'
Unicode string dtype, when creating the ab
structured array, instead of the 'S6'
byte string. The latter dtype would work in Python 2.7, but would write strings like b'NAME_1'
in Python 3.
This table might be helpful for you:
Going down the first column, you will see how the log works in each level. i.e for WARN, (FATAL, ERROR and WARN) will be visible. For OFF, nothing will be visible.
Just an another ussage example for Notepad++ (regular expression search mode)
Find: (g|c|u|d)(et|reate|pdate|elete)_(.)([^\s (]+)
Replace: \U\1\E$2\U\3\E$4

create_user -> CreateUser
update_user -> UpdateUser
delete_user -> DeleteUser
They are slightly different - the ETag does not have any information that the client can use to determine whether or not to make a request for that file again in the future. If ETag is all it has, it will always have to make a request. However, when the server reads the ETag from the client request, the server can then determine whether to send the file (HTTP 200) or tell the client to just use their local copy (HTTP 304). An ETag is basically just a checksum for a file that semantically changes when the content of the file changes.
The Expires header is used by the client (and proxies/caches) to determine whether or not it even needs to make a request to the server at all. The closer you are to the Expires date, the more likely it is the client (or proxy) will make an HTTP request for that file from the server.
So really what you want to do is use BOTH headers - set the Expires header to a reasonable value based on how often the content changes. Then configure ETags to be sent so that when clients DO send a request to the server, it can more easily determine whether or not to send the file back.
One last note about ETag - if you are using a load-balanced server setup with multiple machines running Apache you will probably want to turn off ETag generation. This is because inodes are used as part of the ETag hash algorithm which will be different between the servers. You can configure Apache to not use inodes as part of the calculation but then you'd want to make sure the timestamps on the files are exactly the same, to ensure the same ETag gets generated for all servers.

Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)
import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1
u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0
#option 1
#keep index of t
u.index = t.index
#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)
#now concat will keep number of rows
r=pd.concat([t,u], axis=1)
I read the answers. Then I noticed for me that the check box was already unchecked, but it still always reloaded the files. This is the Settings->Preferences->MISC->"Remember current session for next launch" check box on version 6.3.2. The following got rid of the problem:
1. Check the check box.
2. Exit the program.
3. Start the program again.
4. Uncheck the checkbox.
In Java 8 you can do something like this:
You first need an Enum:
public enum Color {
BLUE, YELLOW, RED
}
Car class:
public class Car {
Color color;
....
public Color getColor() {
return color;
}
public void setColor(Color color) {
this.color = color;
}
}
And then, using your car list, you can simply do:
Collections.sort(carList, Comparator:comparing(CarSort::getColor));
If you are using WebClient
, it has a Proxy property you can use.
As other have mentioned, there are several ways to automate proxy setting detection/usage
Web.Config:
<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true">
<proxy usesystemdefault="true" bypassonlocal="true" />
</defaultProxy>
</system.net>
Use of the WebProxy class as described in this article.
You can also cofigure the proxy settings directly (config or code) and your app will then use those.
Web.Config:
<system.net>
<defaultProxy>
<proxy
proxyaddress="http://[proxy address]:[proxy port]"
bypassonlocal="false"
/>
</defaultProxy>
</system.net>
Code:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("url");
WebProxy myproxy = new WebProxy("[proxy address]:[proxy port]", false);
request.Proxy = myproxy;
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
I have also faced this issue. I resolved this following step.
Check android sdk path in Environment Veritable.

You can use the first selector.
var header = $('.header:first')
Your form should look like this :
<form action="myprocessingscript.php" method="POST">
<input name="field1" type="text" />
<input name="field2" type="text" />
<input type="submit" name="submit" value="Save Data">
</form>
and the PHP
<?php
if(isset($_POST['field1']) && isset($_POST['field2'])) {
$data = $_POST['field1'] . '-' . $_POST['field2'] . "\r\n";
$ret = file_put_contents('/tmp/mydata.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo "$ret bytes written to file";
}
}
else {
die('no post data to process');
}
I wrote to /tmp/mydata.txt
because this way I know exactly where it is. using data.txt
writes to that file in the current working directory which I know nothing of in your example.
file_put_contents
opens, writes and closes files for you. Don't mess with it.

This works 1) for multiline text as well 2) and even in IE9!
<div class="measureText" id="measureText">
</div>
.measureText {
margin: 0;
padding: 0;
border: 0;
font-family: Arial;
position: fixed;
visibility: hidden;
height: auto;
width: auto;
white-space: pre-wrap;
line-height: 100%;
}
function getTextFieldMeasure(fontSize, value) {
const div = document.getElementById("measureText");
// returns wrong result for multiline text with last line empty
let arr = value.split('\n');
if (arr[arr.length-1].length == 0) {
value += '.';
}
div.innerText = value;
div.style['font-size']= fontSize + "px";
let rect = div.getBoundingClientRect();
return {width: rect.width, height: rect.height};
};
To append entries to the table:
for row in data:
name = ??? # figure out the name of the drug
number = ??? # figure out the number you want to append
drug_dictionary[name].append(number)
To loop through the data:
for name, numbers in drug_dictionary.items():
print name, numbers
I had a similar issue.
Cause:
import HomeComponent from "components/HomeComponent";
Solution:
import HomeComponent from "./components/HomeComponent";
NOTE: ./
was before components. You can read @Zac Kwan's post above on how to use import
I had this issue when I was trying to make my Docker container smaller. It was because I'd installed Python 2.7 with:
apt-get install -y --no-install-recommends python
And I should not have included the --no-install-recommends
flag:
apt-get install -y python
You can also pad a string to the required length using Guava's Strings.padEnd(String input, int minLength, char padding)
use Python OS module to find files with specific extension.
the simple example is here :
import os
# This is the path where you want to search
path = r'd:'
# this is extension you want to detect
extension = '.txt' # this can be : .jpg .png .xls .log .....
for root, dirs_list, files_list in os.walk(path):
for file_name in files_list:
if os.path.splitext(file_name)[-1] == extension:
file_name_path = os.path.join(root, file_name)
print file_name
print file_name_path # This is the full path of the filter file
If the size of the subdirectory is not particularly huge, AND you wish to stay away from the CLI, here's a quick solution to manually reset the sub-directory:
Cheers. You just manually reset a sub-directory in your feature branch to be same as that of master branch !!
How about this?
<div class="relative">
<div class="yellow-div"></div>
<div class="yellow-div"></div>
<div class="absolute"></div>
</div>
.relative{
position:relative;
}
.absolute {
position:absolute;
width: 40px;
height: 100px;
background: #000;
z-index: 1;
top:30px;
left:0px;
}
.yellow-div {
position:relative;
width: 200px;
height: 50px;
background: yellow;
margin-bottom:4px;
z-index:0;
}
use the relative div as wrapper and let the yellow div's have normal positioning.
Only the black block need to have an absolute position then.
Here's an example of posting form data to add a user to a database. Check request.method == "POST"
to check if the form was submitted. Use keys from request.form
to get the form data. Render an HTML template with a <form>
otherwise. The fields in the form should have name
attributes that match the keys in request.form
.
from flask import Flask, request, render_template
app = Flask(__name__)
@app.route("/user/add", methods=["GET", "POST"])
def add_user():
if request.method == "POST":
user = User(
username=request.form["username"],
email=request.form["email"],
)
db.session.add(user)
db.session.commit()
return redirect(url_for("index"))
return render_template("add_user.html")
<form method="post">
<label for="username">Username</label>
<input type="text" name="username" id="username">
<label for="email">Email</label>
<input type="email" name="email" id="email">
<input type="submit">
</form>
