I know that this is an old question but I wanted to write my answer for visual learners. I couldn't find any diagrams explaining output buffering on the worldwide-web so I made a diagram myself in Windows mspaint.exe
.
If output buffering is turned off, then echo
will send data immediately to the Browser.
If output buffering is turned on, then an echo
will send data to the output buffer before sending it to the Browser.
phpinfo
To see whether Output buffering is turned on / off please refer to phpinfo at the core section. The output_buffering
directive will tell you if Output buffering is on/off.
In this case the output_buffering
value is 4096 which means that the buffer size is 4 KB. It also means that Output buffering is turned on, on the Web server.
php.ini
It's possible to turn on/off and change buffer size by changing the value of the output_buffering
directive. Just find it in php.ini
, change it to the setting of your choice, and restart the Web server. You can find a sample of my php.ini
below.
; Output buffering is a mechanism for controlling how much output data
; (excluding headers and cookies) PHP should keep internally before pushing that
; data to the client. If your application's output exceeds this setting, PHP
; will send that data in chunks of roughly the size you specify.
; Turning on this setting and managing its maximum buffer size can yield some
; interesting side-effects depending on your application and web server.
; You may be able to send headers and cookies after you've already sent output
; through print or echo. You also may see performance benefits if your server is
; emitting less packets due to buffered output versus PHP streaming the output
; as it gets it. On production servers, 4096 bytes is a good setting for performance
; reasons.
; Note: Output buffering can also be controlled via Output Buffering Control
; functions.
; Possible Values:
; On = Enabled and buffer is unlimited. (Use with caution)
; Off = Disabled
; Integer = Enables the buffer and sets its maximum size in bytes.
; Note: This directive is hardcoded to Off for the CLI SAPI
; Default Value: Off
; Development Value: 4096
; Production Value: 4096
; http://php.net/output-buffering
output_buffering = 4096
The directive output_buffering
is not the only configurable directive regarding Output buffering. You can find other configurable Output buffering directives here: http://php.net/manual/en/outcontrol.configuration.php
Example: ob_get_clean()
Below you can see how to capture an echo
and manipulate it before sending it to the browser.
// Turn on output buffering
ob_start();
echo 'Hello World'; // save to output buffer
$output = ob_get_clean(); // Get content from the output buffer, and discard the output buffer ...
$output = strtoupper($output); // manipulate the output
echo $output; // send to output stream / Browser
// OUTPUT:
HELLO WORLD
Examples: Hackingwithphp.com
More info about Output buffer with examples can be found here:
It flushes the internal buffer, which is supposed to cause the OS to write out the buffer to the file.[1] Python uses the OS's default buffering unless you configure it do otherwise.
But sometimes the OS still chooses not to cooperate. Especially with wonderful things like write-delays in Windows/NTFS. Basically the internal buffer is flushed, but the OS buffer is still holding on to it. So you have to tell the OS to write it to disk with os.fsync()
in those cases.
I prefer:
ob_start();
echo("Hello there!");
$output = ob_get_clean(); //Get current buffer contents and delete current output buffer
composer.phar can be ran on its own, no need to prefix it with php
. This should solve your problem (being in the difference of bash's $PATH and php's include_path).
Check out javapassion, they have a number of courses that encompass web programming, and were free (until circumstances conspired to make the website need to support itself).
Even with the nominal fee, you get a lot for an entire year. It's a bargain compared to the amount of time you'll be investing.
The other options are to look to Oracle's online tutorials, they lack the glitz of Codeacademy, but are surprisingly good. I haven't read the one on web programming, that might be embedded in the Java EE tutorial(s), which is not tuned for a new beginner to Java.
You can use Xembly, a small open source library that makes this XML creating process much more intuitive:
String xml = new Xembler(
new Directives()
.add("root")
.add("order")
.attr("id", "553")
.set("$140.00")
).xml();
Xembly is a wrapper around native Java DOM, and is a very lightweight library.

Use the new CSS viewport units vw
and vh
(viewport width / viewport height)
Resize vertically and horizontally and you'll see that the element will always fill the maximum viewport size without breaking the ratio and without scrollbars!
div

height: 56.25vw; /* height:width ratio = 9/16 = .5625 */
background: pink;

First the CSS - tweak this however you like:
a.selected {
background-color:#1F75CC;
color:white;
z-index:100;
}
.messagepop {
background-color:#FFFFFF;
border:1px solid #999999;
cursor:default;
display:none;
margin-top: 15px;
position:absolute;
text-align:left;
width:394px;
z-index:50;
padding: 25px 25px 20px;
}
label {
display: block;
margin-bottom: 3px;
padding-left: 15px;
text-indent: -15px;
}
.messagepop p, .messagepop.div {
border-bottom: 1px solid #EFEFEF;
margin: 8px 0;
padding-bottom: 8px;
}
And the JavaScript:
function deselect(e) {
$('.pop').slideFadeToggle(function() {
e.removeClass('selected');
});
}
$(function() {
$('#contact').on('click', function() {
if($(this).hasClass('selected')) {
deselect($(this));
} else {
$(this).addClass('selected');
$('.pop').slideFadeToggle();
}
return false;
});
$('.close').on('click', function() {
deselect($('#contact'));
return false;
});
});
$.fn.slideFadeToggle = function(easing, callback) {
return this.animate({ opacity: 'toggle', height: 'toggle' }, 'fast', easing, callback);
};
And finally the html:
<div class="messagepop pop">
<form method="post" id="new_message" action="/messages">
<p><label for="email">Your email or name</label><input type="text" size="30" name="email" id="email" /></p>
<p><label for="body">Message</label><textarea rows="6" name="body" id="body" cols="35"></textarea></p>
<p><input type="submit" value="Send Message" name="commit" id="message_submit"/> or <a class="close" href="/">Cancel</a></p>
</form>
</div>
<a href="/contact" id="contact">Contact Us</a>
Here is a jsfiddle demo and implementation.
Depending on the situation you may want to load the popup content via an ajax call. It's best to avoid this if possible as it may give the user a more significant delay before seeing the content. Here couple changes that you'll want to make if you take this approach.
HTML becomes:
<div>
<div class="messagepop pop"></div>
<a href="/contact" id="contact">Contact Us</a>
</div>
And the general idea of the JavaScript becomes:
$("#contact").on('click', function() {
if($(this).hasClass("selected")) {
deselect();
} else {
$(this).addClass("selected");
$.get(this.href, function(data) {
$(".pop").html(data).slideFadeToggle(function() {
$("input[type=text]:first").focus();
});
}
}
return false;
});

For SQL 2008 you can backup log to nul
device:
BACKUP LOG [databaseName]
TO DISK = 'nul:' WITH STATS = 10
And then use DBCC SHRINKFILE
to truncate the log file.
Assume i have two arrays. The first one has student details and the student marks details. Both arrays have the common key, that is ‘studentId’
let studentDetails = [
{ studentId: 1, studentName: 'Sathish', gender: 'Male', age: 15 },
{ studentId: 2, studentName: 'kumar', gender: 'Male', age: 16 },
{ studentId: 3, studentName: 'Roja', gender: 'Female', age: 15 },
{studentId: 4, studentName: 'Nayanthara', gender: 'Female', age: 16},
];
let studentMark = [
{ studentId: 1, mark1: 80, mark2: 90, mark3: 100 },
{ studentId: 2, mark1: 80, mark2: 90, mark3: 100 },
{ studentId: 3, mark1: 80, mark2: 90, mark3: 100 },
{ studentId: 4, mark1: 80, mark2: 90, mark3: 100 },
];
I want to merge the two arrays based on the key ‘studentId’. I have created a function to merge the two arrays.
const mergeById = (array1, array2) =>
array1.map(itm => ({
...array2.find((item) => (item.studentId === itm.studentId) && item),
...itm
}));
here is the code to get the final result
let result = mergeById(studentDetails, studentMark
);
[
{"studentId":1,"mark1":80,"mark2":90,"mark3":100,"studentName":"Sathish","gender":"Male","age":15},{"studentId":2,"mark1":80,"mark2":90,"mark3":100,"studentName":"kumar","gender":"Male","age":16},{"studentId":3,"mark1":80,"mark2":90,"mark3":100,"studentName":"Roja","gender":"Female","age":15},{"studentId":4,"mark1":80,"mark2":90,"mark3":100,"studentName":"Nayanthara","gender":"Female","age":16}

You can do it with pure JS too:
// Create the XHR object.
function createCORSRequest(method, url) {
var xhr = new XMLHttpRequest();
if ("withCredentials" in xhr) {
// XHR for Chrome/Firefox/Opera/Safari.
xhr.open(method, url, true);
} else if (typeof XDomainRequest != "undefined") {
// XDomainRequest for IE.
xhr = new XDomainRequest();
xhr.open(method, url);
} else {
// CORS not supported.
xhr = null;
}
return xhr;
}
// Make the actual CORS request.
function makeCorsRequest() {
// This is a sample server that supports CORS.
var url = 'http://html5rocks-cors.s3-website-us-east-1.amazonaws.com/index.html';
var xhr = createCORSRequest('GET', url);
if (!xhr) {
alert('CORS not supported');
return;
}
// Response handlers.
xhr.onload = function() {
var text = xhr.responseText;
alert('Response from CORS request to ' + url + ': ' + text);
};
xhr.onerror = function() {
alert('Woops, there was an error making the request.');
};
xhr.send();
}

Using a DateTime parameter is the best way. However, if you still want to pass a DateTime as a string, then the CAST should not be necessary provided that a language agnostic format is used.
e.g.
Given a table created like :
create table t1 (id int, EndDate DATETIME)
insert t1 (id, EndDate) values (1, GETDATE())
The following should always work :
update t1 set EndDate = '20100525' where id = 1 -- YYYYMMDD is language agnostic
The following will work :
SET LANGUAGE us_english
update t1 set EndDate = '2010-05-25' where id = 1
However, this won't :
SET LANGUAGE british
update t1 set EndDate = '2010-05-25' where id = 1
This is because 'YYYY-MM-DD' is not a language agnostic format (from SQL server's point of view) .
The ISO 'YYYY-MM-DDThh:mm:ss' format is also language agnostic, and useful when you need to pass a non-zero time.

When calling file_get_contents
on a URL, one should use the stream_create_context
function, which is fairly well documented on php.net.
This is more or less exactly covered on the following page at php.net in the user comments section: http://php.net/manual/en/function.stream-context-create.php
for me, it was because of all the outgoing files, i.e workspace is not in sync with SVN, due to the 'target' folders (maven project, or when building web project), add them to svn:ignore.
There is a comprehensive list of tools on the PostgreSQL Wiki:
https://wiki.postgresql.org/wiki/PostgreSQL_Clients
And of course PostgreSQL itself comes with pgAdmin, a GUI tool for accessing Postgres databases.
If you use the string literal exactly as you have shown us, the problem is the ;
character at the end. You may not include that in the query string in the JDBC calls.
As you are inserting only a single row, a regular INSERT
should be just fine even when inserting multiple rows. Using a batched statement is probable more efficient anywy. No need for INSERT ALL
. Additionally you don't need the temporary clob and all that. You can simplify your method to something like this (assuming I got the parameters right):
String query1 = "select substr(to_char(max_data),1,4) as year, " +
"substr(to_char(max_data),5,6) as month, max_data " +
"from dss_fin_user.acq_dashboard_src_load_success " +
"where source = 'CHQ PeopleSoft FS'";
String query2 = ".....";
String sql = "insert into domo_queries (clob_column) values (?)";
PreparedStatement pstmt = con.prepareStatement(sql);
StringReader reader = new StringReader(query1);
pstmt.setCharacterStream(1, reader, query1.length());
pstmt.addBatch();
reader = new StringReader(query2);
pstmt.setCharacterStream(1, reader, query2.length());
pstmt.addBatch();
pstmt.executeBatch();
con.commit();
You should replace WebDriver wb = new FirefoxDriver();
with driver = new FirefoxDriver();
in your @Before
Annotation.
As you are accessing driver
object with null or you can make wb
reference variable as global variable.

For ExcelDataReader v3.6.0 and above. I struggled a bit to iterate over the Rows. So here's a little more to the above code. Hope it helps for few atleast.
using (var stream = System.IO.File.Open(copyPath, FileMode.Open, FileAccess.Read))
{
IExcelDataReader excelDataReader = ExcelDataReader.ExcelReaderFactory.CreateReader(stream);
var conf = new ExcelDataSetConfiguration()
{
ConfigureDataTable = a => new ExcelDataTableConfiguration
{
UseHeaderRow = true
}
};
DataSet dataSet = excelDataReader.AsDataSet(conf);
//DataTable dataTable = dataSet.Tables["Sheet1"];
DataRowCollection row = dataSet.Tables["Sheet1"].Rows;
//DataColumnCollection col = dataSet.Tables["Sheet1"].Columns;
List<object> rowDataList = null;
List<object> allRowsList = new List<object>();
foreach (DataRow item in row)
{
rowDataList = item.ItemArray.ToList(); //list of each rows
allRowsList.Add(rowDataList); //adding the above list of each row to another list
}
}
getCurrentActivity() is also in ReactContextBaseJavaModule.
(Since the this question was initially asked, many Android app also has ReactNative component - hybrid app.)
class ReactContext in ReactNative has the whole set of logic to maintain mCurrentActivity which is returned in getCurrentActivity().
Note: I wish getCurrentActivity() is implemented in Android Application class.
I always compare an MD5 hash of the modulus using these commands:
Certificate: openssl x509 -noout -modulus -in server.crt | openssl md5
Private Key: openssl rsa -noout -modulus -in server.key | openssl md5
CSR: openssl req -noout -modulus -in server.csr | openssl md5
If the hashes match, then those two files go together.
I would make a new image of the dog's silhouette (black) and the rest the same as the original image. In the html, add a wrapper div with this silhouette as as background. Now, make the original image semi-transparent. The dog will become darker and the background of the dog will stay the same. You can do :hover tricks by setting the opacity of the original image to 100% on hover. Then the dog pops out when you mouse over him!
style
.wrapper{background-image:url(silhouette.png);}
.original{opacity:0.7:}
.original:hover{opacity:1}
<div class="wrapper">
<div class="img">
<img src="original.png">
</div>

data-target
is used by bootstrap to make your life easier. You (mostly) do not need to write a single line of Javascript to use their pre-made JavaScript components.
The data-target
attribute should contain a CSS selector that points to the HTML Element that will be changed.
<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
[...]
</div>
In this example, the button has data-target="#myModal"
, if you click on it, <div id="myModal">...</div>
will be modified (in this case faded in).
This happens because #myModal
in CSS selectors points to elements that have an id
attribute with the myModal
value.
Further information about the HTML5 "data-" attribute: https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes
Verilog thinks in bits, so reg [7:0] a[0:3]
will give you a 4x8 bit array (=4x1 byte array). You get the first byte out of this with a[0]
. The third bit of the 2nd byte is a[1][2]
.
For a 2D array of bytes, first check your simulator/compiler. Older versions (pre '01, I believe) won't support this. Then reg [7:0] a [0:3] [0:3]
will give you a 2D array of bytes. A single bit can be accessed with a[2][0][7]
for example.
reg [7:0] a [0:3];
reg [7:0] b [0:3] [0:3];
reg [7:0] c;
reg d;
initial begin
for (int i=0; i<=3; i++) begin
a[i] = i[7:0];
end
c = a[0];
d = a[1][2];
// using 2D
for (int i=0; i<=3; i++)
for (int j=0; j<=3; j++)
b[i][j] = i*j; // watch this if you're building hardware

When i have this problem, i find running the cleanup command directly on the problem path generally seems to work. Then I'll run cleanup from the working root again, and it'll complain about some other directory. and i just repeat until it stops complaining.
(I presume you are aware that using UDP(User Datagram Protocol) does not guarantee delivery, checks for duplicates and congestion control and will just answer your question).
In your server this line:
var data = udpServer.Receive(ref groupEP);
re-assigns groupEP
from what you had to a the address you receive something on.
This line:
udpServer.Send(new byte[] { 1 }, 1);
Will not work since you have not specified who to send the data to. (It works on your client because you called connect which means send will always be sent to the end point you connected to, of course we don't want that on the server as we could have many clients). I would:
UdpClient udpServer = new UdpClient(UDP_LISTEN_PORT);
while (true)
{
var remoteEP = new IPEndPoint(IPAddress.Any, 11000);
var data = udpServer.Receive(ref remoteEP);
udpServer.Send(new byte[] { 1 }, 1, remoteEP); // if data is received reply letting the client know that we got his data
}
Also if you have server and client on the same machine you should have them on different ports.
map()
doesn't return a list, it returns a map
object.
You need to call list(map)
if you want it to be a list again.
Even better,
from itertools import imap
payIntList = list(imap(int, payList))
Won't take up a bunch of memory creating an intermediate object, it will just pass the ints
out as it creates them.
Also, you can do if choice.lower() == 'n':
so you don't have to do it twice.
Python supports +=
: you can do payIntList[i] += 1000
and numElements += 1
if you want.
If you really want to be tricky:
from itertools import count
for numElements in count(1):
payList.append(raw_input("Enter the pay amount: "))
if raw_input("Do you wish to continue(y/n)?").lower() == 'n':
break
and / or
for payInt in payIntList:
payInt += 1000
print payInt
Also, four spaces is the standard indent amount in Python.
I hated any complete solutions shown here, I did a mix and tested now, worked for any event handler:
public class MyMain()
public void MyMethod() {
AnotherClass.TheEventHandler += DoSomeThing;
}
private void DoSomething(object sender, EventArgs e) {
Debug.WriteLine("I did something");
AnotherClass.ClearAllDelegatesOfTheEventHandler();
}
}
public static class AnotherClass {
public static event EventHandler TheEventHandler;
public static void ClearAllDelegatesOfTheEventHandler() {
foreach (Delegate d in TheEventHandler.GetInvocationList())
{
TheEventHandler -= (EventHandler)d;
}
}
}
Easy! Thanks for Stephen Punak.
I used it because I use a generic local method to remove the delegates and the local method was called after different cases, when different delegates are setted.
To give a more up to date answer to this question: yes, .Net includes JSON seriliazer/deserliazer since version 3.5 through the System.Runtime.Serialization.Json Namespace: http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json(v=vs.110).aspx
But according to the creator of JSON.Net, the .Net Framework compared to his open source implementation is very much slower.
With that firmly in mind, let's do this! Once your apps hit a certain point, denormalizing data is very common. Done correctly, it can save numerous expensive database lookups at the cost of a little more housekeeping.
To return a list
of friend names we'll need to create a custom Django Field class that will return a list when accessed.
David Cramer posted a guide to creating a SeperatedValueField on his blog. Here is the code:
from django.db import models
class SeparatedValuesField(models.TextField):
__metaclass__ = models.SubfieldBase
def __init__(self, *args, **kwargs):
self.token = kwargs.pop('token', ',')

The logic of this code deals with serializing and deserializing values from the database to Python and vice versa. Now you can easily import and use our custom field in the model class:
from django.db import models
from custom.fields import SeparatedValuesField
class Person(models.Model):
name = models.CharField(max_length=64)
friends = SeparatedValuesField()
I've been doing it this way:
class Event(list):
"""Event subscription.
A list of callable objects. Calling an instance of this will cause a
call to each item in the list in ascending order by index.
Example Usage:
>>> def f(x):
... print 'f(%s)' % x
>>> def g(x):
... print 'g(%s)' % x
>>> e = Event()
>>> e()
>>> e.append(f)
>>> e(123)
f(123)
>>> e.remove(f)
>>> e()
>>> e += (f, g)
>>> e(10)
f(10)
g(10)
>>> del e[0]
>>> e(2)
g(2)
"""
def __call__(self, *args, **kwargs):
for f in self:
f(*args, **kwargs)
def __repr__(self):
return "Event(%s)" % list.__repr__(self)
However, like with everything else I've seen, there is no auto generated pydoc for this, and no signatures, which really sucks.
Does this work for you:

Here's my solution using only Graph API Explorer & Access Token Debugger:
(Tested with API Version 2.9-2.11, 3.0-3.1)
If your class extends JFrame then use this.setTitle(newTitle.getText());
If not and it contains a JFrame let's say named myFrame, then use myFrame.setTitle(newTitle.getText());
Now that you have posted your program, it is obvious that you need only one JTextField to get the new title. These changes will do the trick:
JTextField poolLengthText, poolWidthText, poolDepthText, poolVolumeText, hotTub,
hotTubLengthText, hotTubWidthText, hotTubDepthText, hotTubVolumeText, temp, results,
newTitle;
and:
public void createOptions()
{
options = new JPanel();
options.setLayout(null);
JLabel labelOptions = new JLabel("Change Company Name:");
labelOptions.setBounds(120, 10, 150, 20);
options.add(labelOptions);
newTitle = new JTextField("Some Title");
newTitle.setBounds(80, 40, 225, 20);
options.add(newTitle);
// myTitle = new JTextField("My Title...");
// myTitle.setBounds(80, 40, 225, 20);
// myTitle.add(labelOptions);
JButton newName = new JButton("Set New Name");
newName.setBounds(60, 80, 150, 20);
newName.addActionListener(this);
options.add(newName);
JButton Exit = new JButton("Exit");
Exit.setBounds(250, 80, 80, 20);
Exit.addActionListener(this);
options.add(Exit);
}
and:
private void New_Name()
{
this.setTitle(newTitle.getText());
}

Here's another way of listing files inside a directory (using a different tool, not as efficient as some of the other answers).
cd "search_dir"
for [ z in `echo *` ]; do
echo "$z"
done
echo *
Outputs all files of the current directory. The for
loop iterates over each file name and prints to stdout.
Additionally, If looking for directories inside the directory then place this inside the for
loop:
if [ test -d $z ]; then
echo "$z is a directory"
fi
test -d
checks if the file is a directory.
Here's how
double fRand(double fMin, double fMax)
{
double f = (double)rand() / RAND_MAX;
return fMin + f * (fMax - fMin);
}
Remember to call srand() with a proper seed each time your program starts.

The tutorial @Henrik mentioned is an excellent resource for learning how to create plots with the ggplot2
package.
An example with your data:
# transforming the data from wide to long
library(reshape2)
dfm <- melt(df, id = "TY")
# creating a scatterplot
ggplot(data = dfm, aes(x = TY, y = value, color = variable)) +
geom_point(size=5) +
labs(title = "Temperatures\n", x = "TY [°C]", y = "Txxx", color = "Legend Title\n") +
scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
theme_bw() +
theme(axis.text.x = element_text(size = 14), axis.title.x = element_text(size = 16),
axis.text.y = element_text(size = 14), axis.title.y = element_text(size = 16),
plot.title = element_text(size = 20, face = "bold", color = "darkgreen"))
this results in:
As mentioned by @user2739472 in the comments: If you only want to change the legend text labels and not the colours from ggplot's default palette, you can use scale_color_hue(labels = c("T999", "T888"))
instead of scale_color_manual()
.
%>%
is similar to pipe in Unix. For example, in
a <- combined_data_set %>% group_by(Outlet_Identifier) %>% tally()
the output of combined_data_set
will go into group_by
and its output will go into tally
, then the final output is assigned to a
.
This gives you handy and easy way to use functions in series without creating variables and storing intermediate values.
rum[order(rum$T1, -rum$T2 ), ]
Maybe you coul'd use UTF8 bold chars.
For examples: https://yaytext.com/bold-italic/
It works on Chromium 80.0, I don't know on other browsers...
It's because you have:

try:
without a matching except
block after the try:

In addition to the most upvoted answer here, one can also chain axhline
after calling plot
on a pandas
's DataFrame
.
import pandas as pd
(pd.DataFrame([1, 2, 3])
.plot(kind='bar', color='orange')
.axhline(y=1.5));
You may also want to check for the length - emails are a maximum of 254 chars long. I use the apache commons validator and it doesn't check for this.
EDIT: As pointed out by users, don't use MQ, use commit --amend
. This answer is mostly of historic interest now.
As others have mentioned the MQ extension is much more suited for this task, and you don't run the risk of destroying your work. To do this:
Enable the MQ extension, by adding something like this to your hgrc:

mq =
Update to the changeset you want to edit, typically tip:
hg up $rev
Import the current changeset into the queue:
hg qimport -r .
Refresh the patch, and edit the commit message:
hg qrefresh -e
Finish all applied patches (one, in this case) and store them as regular changesets:
hg qfinish -a
I'm not familiar with TortoiseHg, but the commands should be similar to those above. I also believe it's worth mentioning that editing history is risky; you should only do it if you're absolutely certain that the changeset hasn't been pushed to or pulled from anywhere else.

You can iterate through arraylist to identify the index and eventually the object which you need to modify. You can use for-each for the same as below:
for(Customer customer : myList) {
if(customer!=null && "Doe".equals(customer.getName())) {
customer.setEmail("[email protected]");
break;
}
}
Here customer is a reference to the object present in Arraylist, If you change any property of this customer reference, these changes will reflect in your object stored in Arraylist.
There are two uses for RAISE_APPLICATION_ERROR. The first is to replace generic Oracle exception messages with our own, more meaningful messages. The second is to create exception conditions of our own, when Oracle would not throw them.
The following procedure illustrates both usages. It enforces a business rule that new employees cannot be hired in the future. It also overrides two Oracle exceptions. One is DUP_VAL_ON_INDEX, which is thrown by a unique key on EMP(ENAME)
. The other is a a user-defined exception thrown when the foreign key between EMP(MGR)
and EMP(EMPNO)
is violated (because a manager must be an existing employee).
create or replace procedure new_emp
( p_name in emp.ename%type
, p_sal in emp.sal%type
, p_job in emp.job%type
, p_dept in emp.deptno%type
, p_mgr in emp.mgr%type
, p_hired in emp.hiredate%type := sysdate )
is
invalid_manager exception;
PRAGMA EXCEPTION_INIT(invalid_manager, -2291);
dummy varchar2(1);
begin
-- check hiredate is valid
if trunc(p_hired) > trunc(sysdate)
then

, 'NEW_EMP::hiredate cannot be in the future');
end if;
insert into emp
( ename
, sal
, job
, deptno
, mgr
, hiredate )
values
( p_name
, p_sal
, p_job
, p_dept
, p_mgr
, trunc(p_hired) );
exception
when dup_val_on_index then
raise_application_error
(-20001

Note the different output from the two calls to RAISE_APPLICATION_ERROR in the EXCEPTIONS block. Setting the optional third argument to TRUE means RAISE_APPLICATION_ERROR includes the triggering exception in the stack, which can be useful for diagnosis.
There is more useful information in the PL/SQL User's Guide.

In Java (or other languages), using Property/Attribute depends on usage:
Property used when value doesn't change very often (usually used at startup or for environment variable)
Attributes is a value (object child) of an Element (object) which can change very often/all the time and be or not persistent
If you want know, the how may nodejs processes running then you can use this command
ps -aef | grep node
So it will give list of nodejs process with it's project name. It will be helpful when you are running multipe nodejs application & you want kill specific process for the specific project.
Above command will give output like
XXX 12886 1741 1 12:36 ? 00:00:05 /home/username/.nvm/versions/node/v9.2.0/bin/node --inspect-brk=43443 /node application running path.
So to kill you can use following command
kill -9 12886
So it will kill the spcefic node process
%d
and %s
are placeholders, they work as a replaceable variable. For example, if you create 2 variables
variable_one = "Stackoverflow"
variable_two = 45
you can assign those variables to a sentence in a string using a tuple of the variables.
variable_3 = "I was searching for an answer in %s and found more than %d answers to my question"
Note that %s
works for String and %d
work for numerical or decimal variables.
if you print variable_3
it would look like this
print(variable_3 % (variable_one, variable_two))
I was searching for an answer in StackOverflow and found more than 45 answers to my question.
For all kind of files, subdirectories included:
import os
list = os.listdir(dir) # dir is your directory path
number_files = len(list)
print number_files
Only files (avoiding subdirectories):
import os
onlyfiles = next(os.walk(dir))[2] #dir is your directory path as string
print len(onlyfiles)
It only changes the directory for the script itself, while your current directory stays the same.
You might want to use a symbolic link instead. It allows you to make a "shortcut" to a file or directory, so you'd only have to type something like cd my-project
.
Assuming $foo
is an integer:
$answer = (int) (floor(($foo + 5) / 6) * 6)
I'm not sure if someone will ever see this answer but here it is. The idea here is to simply detect if any click was done outside the element itself.
I first start by giving an id to the main div of my "dropdown".
<template>
<div class="relative" id="dropdown">
<div @click="openDropdown = !openDropdown" class="cursor-pointer">
<slot name="trigger" />
</div>
<div
class="absolute mt-2 w-48 origin-top-right right-0 text-red bg-tertiary text-sm text-black"
v-show="openDropdown"
@click="openDropdown = false"
>
<slot name="content" />
</div>
</div>
</template>
And then I just loop thru the path of the mouse event and see if the div with my id "dropdown" is there. If it is, then we good, if it is no, then we close the dropdown.
<script>
export default {
data() {
return {
openDropdown: false,
};
},
created() {
document.addEventListener("click", (e) => {
let me = false;
for (let index = 0; index < e.path.length; index++) {
const element = e.path[index];
if (element.id == "dropdown") {
me = true;
return;
}
}
if (!me) this.openDropdown = false;
});
}
};
</script>
I'm pretty sure this can bring performance issues if you have many nested elements, but I found this as the most lazy-friendly way of doing it.
I discovered git-annex recently which I find awesome. It was designed for managing large files efficiently. I use it for my photo/music (etc.) collections. The development of git-annex is very active. The content of the files can be removed from the Git repository, only the tree hierarchy is tracked by Git (through symlinks). However, to get the content of the file, a second step is necessary after pulling/pushing, e.g.:
$ git annex add mybigfile
$ git commit -m'add mybigfile'
$ git push myremote
$ git annex copy --to myremote mybigfile ## This command copies the actual content to myremote
$ git annex drop mybigfile ## Remove content from local repo
...
$ git annex get mybigfile ## Retrieve the content
## or to specify the remote from which to get:
$ git annex copy --from myremote mybigfile
There are many commands available, and there is a great documentation on the website. A package is available on Debian.
Disabling tracking will also cause your result sets to be streamed into memory. This is more efficient when you're working with large sets of data and don't need the entire set of data all at once.

Fair warning:
element.onclick()
does not behave as expected. It only runs the code within onclick="" attribute
, but does not trigger default behavior.
I had similar issue with radio button not setting to checked, even though onclick
custom function was running fine. Had to add radio.checked = "true";
to set it. Probably the same goes and for other elements (after a.onclick()
there should be also window.location.href = "url";
)

// do stuff
}

Adding to the selected answer (as I haven't enough rep to add comment), one way to see the list of available versions (from ref) try:

.htaccess
is in DOS format, change it to UNIX format (in Notepad++, click Edit>Convert
).htaccess
is in UTF8 Without-BOM, make it WITH BOM.Shell scripts, no matter how they are executed, execute one command after the other. So your code will execute results.sh
after the last command of st_new.sh
has finished.
Now there is a special command which messes this up: &
cmd &
means: "Start a new background process and execute cmd
in it. After starting the background process, immediately continue with the next command in the script."
That means &
doesn't wait for cmd
to do it's work. My guess is that st_new.sh
contains such a command. If that is the case, then you need to modify the script:
cmd &
BACK_PID=$!
This puts the process ID (PID) of the new background process in the variable BACK_PID
. You can then wait for it to end:
while kill -0 $BACK_PID ; do
echo "Process is still active..."
sleep 1
# You can add a timeout here if you want
done
or, if you don't want any special handling/output simply
wait $BACK_PID
Note that some programs automatically start a background process when you run them, even if you omit the &
. Check the documentation, they often have an option to write their PID to a file or you can run them in the foreground with an option and then use the shell's &
command instead to get the PID.
another thing you could try is to rename your old jdk folder, lets say its:
C:\Program Files\Java\jdk1.7.0_04
change it to saomething like:
C:\Program Files\Java\xxxjdk1.7.0_04
Now, you should once again asked to set your jdk folder location on Oracle SqlDeveloper launch, and you can chose the right path.
Not the most elegant solution, but it worked for me.

I am pretty sure that the reason why this problem happened is because of the license of the toolbox (package) in which this function belongs in. Write which divrat
and see what will be the result. If it returns path of the function and the comment Has no license available
, then the problem is related to the license. That means, license of the package is not set correctly. Mostly it happens if the package (toolbox) of this function is added later, i.e., after installation of the original matlab
. Please check and solve the license issue, then it will work fine.

Also notice that you don't need to have $ReqBookID in '' as if it's an Int.

In a signed int
, which is the default value in mysql
, 1 bit
will be used to represent sign
. -1 for negative and 0 for positive.
So if your application insert only positive value it should better specify unsigned.

def __contains__(self, item): return True

# The actual Event class
class Event(object):
def __init__(self, action, min=allMatch, hour=allMatch,

args=(), kwargs={}):
self.mins = conv_to_set(min)

"""Return True if this event should trigger at the specified datetime"""
return ((t.minute in self.mins) and
(t.hour in self.hours) and
(t.day in self.days) and
(t.month in self.months) and
(t.weekday() in self.dow))
def check(self, t):
if self.matchtime(t):
self.action(*self.args, **self.kwargs)
(Note: Not thoroughly tested)
Then your CronTab can be specified in normal python syntax as:
c = CronTab(
Event(perform_backup, 0, 2, dow=6 ),
Event(purge_temps, 0, range(9,18,2), dow=range(0,5))
)
This way you get the full power of Python's argument mechanics (mixing positional and keyword args, and can use symbolic names for names of weeks and months)
The CronTab class would be defined as simply sleeping in minute increments, and calling check() on each event. (There are probably some subtleties with daylight savings time / timezones to be wary of though). Here's a quick implementation:
class CronTab(object):
def __init__(self, *events):
self.events = events
def run(self):
t=datetime(*datetime.now().timetuple()[:5])
while 1:
for e in self.events:
e.check(t)
t += timedelta(minutes=1)
while datetime.now() < t:
time.sleep((t - datetime.now()).seconds)
A few things to note: Python's weekdays / months are zero indexed (unlike cron), and that range excludes the last element, hence syntax like "1-5" becomes range(0,5) - ie [0,1,2,3,4]. If you prefer cron syntax, parsing it shouldn't be too difficult however.
You need ReDim
:
m = 5
n = 8
Dim my_array()
ReDim my_array(1 To m, 1 To n)
For i = 1 To m
For j = 1 To n
my_array(i, j) = i * j
Next
Next
For i = 1 To m
For j = 1 To n
Cells(i, j) = my_array(i, j)
Next
Next
As others have pointed out, your actual problem would be better solved with ranges. You could try something like this:
Dim r1 As Range
Dim r2 As Range
Dim ws1 As Worksheet
Dim ws2 As Worksheet
Set ws1 = Worksheets("Sheet1")
Set ws2 = Worksheets("Sheet2")
totalRow = ws1.Range("A1").End(xlDown).Row
totalCol = ws1.Range("A1").End(xlToRight).Column
Set r1 = ws1.Range(ws1.Cells(1, 1), ws1.Cells(totalRow, totalCol))
Set r2 = ws2.Range(ws2.Cells(1, 1), ws2.Cells(totalRow, totalCol))
r2.Value = r1.Value
For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
While this will not (note the leading space before the opening <?
tag)
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
Also, this will not work either (the echo
will break it):
<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.
add ob_start ();
at the top and at the end add ob_end_flush();
<?php
ob_start();
require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
ob_end_flush();
?>
give me an error as below:
FPDF error: Some data has already been output, can't send PDF
to over come this error:
go to fpdf.php
in that,goto line number 996
function Output($name='', $dest='')
after that make changes like this:
function Output($name='', $dest='') {
ob_clean(); //Output PDF to so
Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.

Granted, as implemented here it isn't very precise and doesn't calculate the elapsed time. But it's dirt simple and sometimes all you need.
I'm not sure if this work in your particular situation, but I've found that padding on the inside div will push content around inside of a div if the containing div is a fixed size. You would have to either float or absolutely position your header element, but otherwise, I haven't tried this for variable size divs.
If you just want to know about your screen width, you can just search for "smallest screen width" in your developer options. You can even edit it.
I found the answer. IE stores passwords in two different locations based on the password type:
%APPDATA%\Microsoft\Credentials
, in encrypted filesHKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2
, encrypted with the urlFrom a very good page on NirSoft.com:
Starting from version 7.0 of Internet Explorer, Microsoft completely changed the way that passwords are saved. In previous versions (4.0 - 6.0), all passwords were saved in a special location in the Registry known as the "Protected Storage". In version 7.0 of Internet Explorer, passwords are saved in different locations, depending on the type of password. Each type of passwords has some limitations in password recovery:
AutoComplete Passwords: These passwords are saved in the following location in the Registry:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2
The passwords are encrypted with the URL of the Web sites that asked for the passwords, and thus they can only be recovered if the URLs are stored in the history file. If you clear the history file, IE PassView won't be able to recover the passwords until you visit again the Web sites that asked for the passwords. Alternatively, you can add a list of URLs of Web sites that requires user name/password into the Web sites file (see below).HTTP Authentication Passwords: These passwords are stored in the Credentials file under
Documents and Settings\Application Data\Microsoft\Credentials
, together with login passwords of LAN computers and other passwords. Due to security limitations, IE PassView can recover these passwords only if you have administrator rights.
In my particular case it answers the question of where; and I decided that I don't want to duplicate that. I'll continue to use CredRead
/CredWrite
, where the user can manage their passwords from within an established UI system in Windows.
The loop attribute should do it:
<video width="320" height="240" autoplay loop>
<source src="movie.mp4" type="video/mp4" />
<source src="movie.ogg" type="video/ogg" />
Your browser does not support the video tag.
</video>
Should you have a problem with the loop attribute (as we had in the past), listen to the videoEnd
event and call the play()
method when it fires.
Note1: I'm not sure about the behavior on Apple's iPad/iPhone, because they have some restrictions against autoplay
.
Note2: loop="true"
and autoplay="autoplay"
are deprecated

.*
.
any character, except newline character, with dotall mode it includes also the newline characters

any amount of the preceding expression, including 0 times
Don't agree with post above. I have a Hero with only English available and I want Spanish.
I installed MoreLocale 2, and it has lots of different languages (Dutch among them). I choose Spanish, Sense UI restarted and EVERYTHING in my phone changed to Spanish: menus, settings, etc. The keyboard predictive text defaulted to Spanish and started suggesting words in Spanish. This means, somewhere within the OS there is a Spanish dictionary hidden and MoreLocale made it available.
The problem is that English is still the only option available in keyboard input language so I can switch to English but can't switch back to Spanish unless I restart Sense UI, which takes a couple of minutes so not a very practical solution.
Still looking for an easier way to do it so please help.

Just use DataRow.IsNull. It has overrides accepting a column index, a column name, or a DataColumn object as parameters.
Example using the column index:
if (table.rows[0].IsNull(0))
{
//Whatever I want to do
}
And although the function is called IsNull
it really compares with DbNull
(which is exactly what you need).
What if I want to check for DbNull but I don't have a DataRow? Use Convert.IsDBNull.
Although jQuery Maphilight plugin does the job, it relies on the outdated verbose imagemap in your html. I would prefer to keep the mapcoordinates external. This could be as JS with the jquery imagemap plugin but it lacks hover states. A nice solution is googles geomap visualisation in flash and JS. But the opensource future for this kind of vectordata however is svg, considering svg support accross all modern browsers, and googles svgweb for a flash convert for IE, why not a jquery plugin to add links and hoverstates to a svg map, like the JS demo here? That way you also avoid the complex step of transforming a vectormap to a imagemap coordinates.
If you use multiple input fields you can set name="file[]" (or any other name). That will put them in an array when you upload them ($_FILES['file'] = array ({file_array},{file_array]..)

According to this thread:
The peer-to-peer Wi-Fi implemented by iOS (and recent versions of OS X) is not compatible with Wi-Fi Direct. Note Just as an aside, you can access peer-to-peer Wi-Fi without using Multipeer Connectivity. The underlying technology is Bonjour + TCP/IP, and you can access that directly from your app. The WiTap sample code shows how.
You simply need to enclose your SELECT
statements in parentheses to indicate that they are subqueries:
SET cityLat = (SELECT cities.lat FROM cities WHERE cities.id = cityID);
Alternatively, you can use MySQL's SELECT ... INTO
syntax. One advantage of this approach is that both cityLat
and cityLng
can be assigned from a single table-access:
SELECT lat, lng INTO cityLat, cityLng FROM cities WHERE id = cityID;
However, the entire procedure can be replaced with a single self-joined SELECT
statement:
SELECT b.*, HAVERSINE(a.lat, a.lng, b.lat, b.lng) AS dist
FROM cities AS a, cities AS b
WHERE a.id = cityID
ORDER BY dist
LIMIT 10;

If you want to make temporary files in Python, there's a module called tempfile in Python's standard libraries. If you want to launch other programs to operate on the file, use tempfile.mkstemp() to create files, and os.fdopen() to access the file descriptors that mkstemp() gives you.
Incidentally, you say you're running commands from a Python program? You should almost certainly be using the subprocess module.
So you can quite merrily write code that looks like:
import subprocess
import tempfile
import os
(fd, filename) = tempfile.mkstemp()
try:
tfile = os.fdopen(fd, "w")
tfile.write("Hello, world!\n")
tfile.close()
subprocess.Popen(["/bin/cat", filename]).wait()
finally:
os.remove(filename)
Running that, you should find that the cat
command worked perfectly well, but the temporary file was deleted in the finally
block. Be aware that you have to delete the temporary file that mkstemp() returns yourself - the library has no way of knowing when you're done with it!
(Edit: I had presumed that NamedTemporaryFile did exactly what you're after, but that might not be so convenient - the file gets deleted immediately when the temp file object is closed, and having other processes open the file before you've closed it won't work on some platforms, notably Windows. Sorry, fail on my part.)
It seems that you want to use step parameter of range function. From documentation:
range(start, stop[, step]) This is a versatile function to create lists containing arithmetic progressions. It is most often used in for loops. The arguments must be plain integers. If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. The full form returns a list of plain integers [start, start + step, start + 2 * step, ...]. If step is positive, the last element is the largest start + i * step less than stop; if step is negative, the last element is the smallest start + i * step greater than stop. step must not be zero (or else ValueError is raised). Example:
>>> range(10) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> range(1, 11) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> range(0, 30, 5) [0, 5, 10, 15, 20, 25]
>>> range(0, 10, 3) [0, 3, 6, 9]
>>> range(0, -10, -1) [0, -1, -2, -3, -4, -5, -6, -7, -8, -9]
>>> range(0) []
>>> range(1, 0) []
In your case to get [0,2,4] you can use:
range(0,6,2)
OR in your case when is a var:
idx = None
for i in range(len(str1)):
if idx and i < idx:
continue
for j in range(len(str2)):
if str1[i+j] != str2[j]:
break
else:
idx = i+j
Full control over file attributes is available in Java 7, as part of the "new" New IO facility (NIO.2). For example, POSIX permissions can be set on an existing file with setPosixFilePermissions()
, or atomically at file creation with methods like createFile()
or newByteChannel()
.
You can create a set of permissions using EnumSet.of()
, but the helper method PosixFilePermissions.fromString()
will uses a conventional format that will be more readable to many developers. For APIs that accept a FileAttribute
, you can wrap the set of permissions with with PosixFilePermissions.asFileAttribute()
.
Set<PosixFilePermission> ownerWritable = PosixFilePermissions.fromString("rw-r--r--");
FileAttribute<?> permissions = PosixFilePermissions.asFileAttribute(ownerWritable);
Files.createFile(path, permissions);
In earlier versions of Java, using native code of your own, or exec
-ing command-line utilities are common approaches.

Here's the strsplit
solution if s
is a vector:
> s <- c("TGAS_1121", "MGAS_1432")
> s1 <- sapply(strsplit(s, split='_', fixed=TRUE), function(x) (x[2]))
> s1
[1] "1121" "1432"
Use the remainder operator (also known as the modulo operator) which returns the remainder of the division and check if it is zero:
if (j % 4 == 0) {
// j is an exact multiple of 4
}
The web site likely uses cookies to store your session information. When you run
curl --user user:pass https://xyz.com/a #works ok
curl https://xyz.com/b #doesn't work
curl
is run twice, in two separate sessions. Thus when the second command runs, the cookies set by the 1st command are not available; it's just as if you logged in to page a
in one browser session, and tried to access page b
in a different one.
What you need to do is save the cookies created by the first command:
curl --user user:pass --cookie-jar ./somefile https://xyz.com/a
and then read them back in when running the second:
curl --cookie ./somefile https://xyz.com/b
Alternatively you can try downloading both files in the same command, which I think will use the same cookies.
This is not so much an answer to your original question as to one of the queries you had in the body of your question.
A little preamble, so that my naming doesn't seem strange:
import matplotlib
from matplotlib import rc
from matplotlib.figure import Figure
ax = self.figure.add_subplot( 111 )
As has been mentioned you can use ticklabel_format to specify that matplotlib should use scientific notation for large or small values:
ax.ticklabel_format(style='sci',scilimits=(-3,4),axis='both')
You can affect the way that this is displayed using the flags in rcParams (from matplotlib import rcParams) or by setting them directly. I haven't found a more elegant way of changing between '1e' and 'x10^' scientific notation than:
ax.xaxis.major.formatter._useMathText = True
This should give you the more Matlab-esc, and indeed arguably better appearance. I think the following should do the same:
rc('text', usetex=True)
sb.AppendLine();
or
sb.Append( "\n" );
And
sb.Append( "\t" );

Since glibc version 2.17, the library linking -lrt
is no longer required.
The clock_*
are now part of the main C library. You can see the change history of glibc 2.17 where this change was done explains the reason for this change:
+* The `clock_*' suite of functions (declared in <time.h>) is now available
+ directly in the main C library. Previously it was necessary to link with
+ -lrt to use these functions. This change has the effect that a
+ single-threaded program that uses a function such as `clock_gettime' (and
+ is not linked with -lrt) will no longer implicitly load the pthreads
+ library at runtime and so will not suffer the overheads associated with
+ multi-thread support in other code such as the C++ runtime library.
If you decide to upgrade glibc, then you can check the compatibility tracker of glibc if you are concerned whether there would be any issues using the newer glibc.
To check the glibc version installed on the system, run the command:
ldd --version
(Of course, if you are using old glibc (<2.17) then you will still need -lrt
.)
Using this
instead of $scope

Edit: At the time writing this answer, I had much more complicated situation than this. After the comments, I tried to reproduce it to understand why it works, but no luck. I think somehow (don't really know why) a new child scope is generated and this
refers to that scope. But if $scope
is used, it actually refers to the parent $scope because of javascript's lexical scope feature.
Would be great if someone having this problem tests this way and inform us.
You could always try doing a ulimit -n 2048
. This will only reset the limit for your current shell and the number you specify must not exceed the hard limit
Each operating system has a different hard limit setup in a configuration file. For instance, the hard open file limit on Solaris can be set on boot from /etc/system.
set rlim_fd_max = 166384
set rlim_fd_cur = 8192
On OS X, this same data must be set in /etc/sysctl.conf.
kern.maxfilesperproc=166384
kern.maxfiles=8192
Under Linux, these settings are often in /etc/security/limits.conf.
There are two kinds of limits:
Soft limits could be set by any user while hard limits are changeable only by root. Limits are a property of a process. They are inherited when a child process is created so system-wide limits should be set during the system initialization in init scripts and user limits should be set during user login for example by using pam_limits.
There are often defaults set when the machine boots. So, even though you may reset your ulimit in an individual shell, you may find that it resets back to the previous value on reboot. You may want to grep your boot scripts for the existence ulimit commands if you want to change the default.
Just a different version of adding a month and subtracting a day for creating reports:
ex: StartofMonth is '2019-10-01'
dateadd(day,-1,dateadd(month,1,StartofMonth))
EndOfMonth will become '2019-10-31'
for further investigation: print out the mssql error message:
$dbhandle = mssql_connect($myServer, $myUser, $myPass) or die("Could not connect to database: ".mssql_get_last_message());
It is also important to specify the port: On MS SQL Server 2000, separate it with a comma:
$myServer = "10.85.80.229:1443";
or
$myServer = "10.85.80.229,1443";
There are multiple remote linux machines, and I need to write a shell script which will execute the same set of commands in each machine. (Including some sudo operations). How can this be done using shell scripting?
You can do this with ssh, for example:
#!/bin/bash
USERNAME=someUser
HOSTS="host1 host2 host3"
SCRIPT="pwd; ls"
for HOSTNAME in ${HOSTS} ; do
ssh -l ${USERNAME} ${HOSTNAME} "${SCRIPT}"
done
When ssh'ing to the remote machine, how to handle when it prompts for RSA fingerprint authentication.
You can add the StrictHostKeyChecking=no
option to ssh:
ssh -o StrictHostKeyChecking=no -l username hostname "pwd; ls"
This will disable the host key check and automatically add the host key to the list of known hosts. If you do not want to have the host added to the known hosts file, add the option -o UserKnownHostsFile=/dev/null
.
Note that this disables certain security checks, for example protection against man-in-the-middle attack. It should therefore not be applied in a security sensitive environment.
Also note that despite errors being hidden, any custom error handler (set with set_error_handler
) will still be executed!
Use the system
function.
system("myfile.sh"); // myfile.sh should be chmod +x
I like using fsockopen open for this.

From the document.getElementsByTagName
I guess you are running the javascript in a browser.
The traditional way to expose functionality to javascript running in the browser is calling a remote URL using AJAX. The X in AJAX is for XML, but nowadays everybody uses JSON instead of XML.
For example, using jQuery you can do something like:
$.getJSON('http://example.com/your/webservice?param1=x¶m2=y',
function(data, textStatus, jqXHR) {
alert(data);
}
)
You will need to implement a python webservice on the server side. For simple webservices I like to use Flask.
A typical implementation looks like:
@app.route("/your/webservice")
def my_webservice():
return jsonify(result=some_function(**request.args))
You can run IronPython (kind of Python.Net) in the browser with silverlight, but I don't know if NLTK is available for IronPython.
Since "Guid" is not nullable, use "Guid.Empty" as default value.
Adding to the solutions of others, I'd like to suggest using the plotly
package for R
, as this has worked well for me.
Below, I'm using the reformatted dataset suggested above, from xyz-tripplets to axis vectors x and y and a matrix z:
x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z
library(plotly)
plot_ly(x=x,y=y,z=z, type="surface")
The rendered surface can be rotated and scaled using the mouse. This works fairly well in RStudio.
You can also try it with the built-in volcano
dataset from R
:
plot_ly(z=volcano, type="surface")
You need to make it a generic method, like this:
public static T ConfigSetting<T>(string settingName)
{
return /* code to convert the setting to T... */
}
But the caller will have to specify the type they expect. You could then potentially use Convert.ChangeType
, assuming that all the relevant types are supported:
public static T ConfigSetting<T>(string settingName)
{
object value = ConfigurationManager.AppSettings[settingName];
return (T) Convert.ChangeType(value, typeof(T));
}
I'm not entirely convinced that all this is a good idea, mind you...
For reference, here is a minimal implementation using Java 8 :
@Override
public void start(Stage mainStage) throws Exception {
Scene scene = new Scene(new Region());
mainStage.setWidth(640);
mainStage.setHeight(480);
mainStage.setScene(scene);
//this makes all stages close and the app exit when the main stage is closed
mainStage.setOnCloseRequest(e -> Platform.exit());
//add real stuff to the scene...
//open secondary stages... etc...
}
Not sure if this is what you're referring to, but this is the list of HTML entities you can use:
List of XML and HTML character entity references
Using the content within the 'Name' column you can just wrap these in an &
and ;
E.g.
,  
, etc.
In C++ it is easy.
std::copy(someStr.c_str(), someStr.c_str()+n, std::ostream_iterator<char>(std::cout, ""));
EDIT: It is also safer to use this with string iterators, so you don't run off the end. I'm not sure what happens with printf and string that are too short, but I'm guess this may be safer.
I had to transfer texts from an Excel file to an xliff file. We had some texts that were originally in uppercase but those translators didn't use uppercase so I used notepad++ as intermediate to do the conversion.
Since I had the mouse in one hand (to mark in Excel and activate the different windows) I disliked the predefined shortcut (Ctrl+Shift+U) as "U" is too far away for my left hand. I first switched it to Ctrl+Shift+X which worked.
Then I realized, that you can create macros easily, so I recorded one doing:
That macro got assigned that very shortcut (Ctrl+Shift+X) and made my life easy :)

For a simple use of slice
, use my extension to Array Class:
Array.prototype.subarray = function(start, end) {
if (!end) { end = -1; }
return this.slice(start, this.length + 1 - (end * -1));
};
Then:
var bigArr = ["a", "b", "c", "fd", "ze"];
Test1:
bigArr.subarray(1, -1);
< ["b", "c", "fd", "ze"]
Test2:
bigArr.subarray(2, -2);
< ["c", "fd"]
Test3:
bigArr.subarray(2);
< ["c", "fd","ze"]

As well as execute immediate you can also use
DBMS_UTILITY.EXEC_DDL_STATEMENT('TRUNCATE TABLE tablename;');
The statement fails because the stored proc is executing DDL and some instances of DDL could invalidate the stored proc. By using the execute immediate or exec_ddl approaches the DDL is implemented through unparsed code.
When doing this you neeed to look out for the fact that DDL issues an implicit commit both before and after execution.
Change the content-type to "application/x-www-form-urlencoded", i solved the problem.
Since I'm separating page elements definitions and page test scenarios using an already-found IWebElement for visibility, it could be done like this:
public static void WaitForElementToBecomeVisibleWithinTimeout(IWebDriver driver, IWebElement element, int timeout)
{
new WebDriverWait(driver, TimeSpan.FromSeconds(timeout)).Until(ElementIsVisible(element));
}
private static Func<IWebDriver, bool> ElementIsVisible(IWebElement element)
{
return driver => {
try
{
return element.Displayed;
}
catch(Exception)
{
// If element is null, stale or if it cannot be located
return false;
}
};
}
Personally I tried the TextInfo.ToTitleCase
method, but, I don´t understand why it doesn´t work when all chars are upper-cased.
Though I like the util function provided by Winston Smith, let me provide the function I'm currently using:
public static String TitleCaseString(String s)
{
if (s == null) return s;
String[] words = s.Split(' ');
for (int i = 0; i < words.Length; i++)
{
if (words[i].Length == 0) continue;
Char firstChar = Char.ToUpper(words[i][0]);
String rest = "";
if (words[i].Length > 1)
{
rest = words[i].Substring(1).ToLower();
}
words[i] = firstChar + rest;
}
return String.Join(" ", words);
}
Playing with some tests strings:
String ts1 = "Converting string to title case in C#";
String ts2 = "C";
String ts3 = "";
String ts4 = " ";
String ts5 = null;
Console.Out.WriteLine(String.Format("|{0}|", TitleCaseString(ts1)));
Console.Out.WriteLine(String.Format("|{0}|", TitleCaseString(ts2)));
Console.Out.WriteLine(String.Format("|{0}|", TitleCaseString(ts3)));
Console.Out.WriteLine(String.Format("|{0}|", TitleCaseString(ts4)));
Console.Out.WriteLine(String.Format("|{0}|", TitleCaseString(ts5)));
Giving output:

pgAdmin has GUI for data import since 1.16. You have to create your table first and then you can import data easily - just right-click on the table name and click on Import.
Yes, it is. You can write :
INSERT INTO courses (name, location, gid)
SELECT name, location, 'whatever you want'
FROM courses
WHERE cid = $ci
or you can get values from another join of the select ...
The dataset:
dat <- read.table(text = "A B C D E F G
1 480 780 431 295 670 360 190
2 720 350 377 255 340 615 345
3 460 480 179 560 60 735 1260
4 220 240 876 789 820 100 75", header = TRUE)
Now you can convert the data frame into a matrix and use the barplot
function.
barplot(as.matrix(dat))
You can get the all record of the date '2016-07-14' by using it
whereDate('date','=','2016-07-14')
Or use the another code for dynamic date
whereDate('date',$date)

There's no round() in the C++98 standard library. You can write one yourself though. The following is an implementation of round-half-up:
double round(double d)
{
return floor(d + 0.5);
}
The probable reason there is no round function in the C++98 standard library is that it can in fact be implemented in different ways. The above is one common way but there are others such as round-to-even, which is less biased and generally better if you're going to do a lot of rounding; it's a bit more complex to implement though.
you can do this as below in typescript
const _params = {} as any;
_params.name ='nazeh abel'
since typescript does not behave like javascript so we have to make the type as any otherwise it won't allow you to assign property dynamically to an object
I trained a neural network in Keras to perform non linear regression on some data. This is some part of my code for testing on new data using previously saved model configuration and weights.
fname = r"C:\Users\tauseef\Desktop\keras\tutorials\BestWeights.hdf5"
modelConfig = joblib.load('modelConfig.pkl')
recreatedModel = Sequential.from_config(modelConfig)
recreatedModel.load_weights(fname)
unseenTestData = np.genfromtxt(r"C:\Users\tauseef\Desktop\keras\arrayOf100Rows257Columns.txt",delimiter=" ")
X_test = unseenTestData
standard_scalerX = StandardScaler()
standard_scalerX.fit(X_test)
X_test_std = standard_scalerX.transform(X_test)
X_test_std = X_test_std.astype('float32')
unseenData_predictions = recreatedModel.predict(X_test_std)
Since I needed this too, I was curious as to which alternative was the fastest.
I found that -- if all you want is a file count -- Baba's solution is a lot faster than the others. I was quite surprised.
Try it out for yourself:
<?php
define('MYDIR', '...');
foreach (array(1, 2, 3) as $i)
{
$t = microtime(true);
$count = run($i);
echo "$i: $count (".(microtime(true) - $t)." s)\n";
}
function run ($n)
{
$func = "countFiles$n";
$x = 0;
for ($f = 0; $f < 5000; $f++)
$x = $func();
return $x;
}
function countFiles1 ()
{
$dir = opendir(MYDIR);
$c = 0;
while (($file = readdir($dir)) !== false)
if (!in_array($file, array('.', '..')))
$c++;
closedir($dir);
return $c;
}
function countFiles2 ()
{
chdir(MYDIR);
return count(glob("*"));
}
function countFiles3 () // Fastest method
{
$f = new FilesystemIterator(MYDIR, FilesystemIterator::SKIP_DOTS);
return iterator_count($f);
}
?>
Test run: (obviously, glob()
doesn't count dot-files)

Dynamic HTML element functionThe code in here with a little bit of modification and simplification:
<input disabled maxlength="3" size="3" value="10" id="counter">
<textarea onkeyup="textCounter(this,'counter',10);" id="message">
</textarea>
<script>
function textCounter(field,field2,maxlimit)
{
var countfield = document.getElementById(field2);
if ( field.value.length > maxlimit ) {
field.value = field.value.substring( 0, maxlimit );
return false;
} else {
countfield.value = maxlimit - field.value.length;
}
}
</script>
Hope this helps!
tip:
When merging the codes with your page, make sure the HTML elements(textarea
, input
) are loaded first before the scripts (Javascript functions)
When this happened to me, it was because I'd blindly copied my settings.xml from a template and it still had the blank <localRepository/>
element. This means that there's no local repository used when resolving dependencies (though your installed artifacts do still get put in the default location). When I'd replaced that with <localRepository>${user.home}\.m2\repository</localRepository>
it started working.
For *nix, that would be <localRepository>${user.home}/.m2/repository</localRepository>
, I suppose.
Just call the action no need for redirect to action
or the new
keyword for model.
[HttpPost]
public ActionResult FillStudent(Student student1)
{
return GetStudent(student1); //this will also work
}
public ActionResult GetStudent(Student student)
{
return View(student);
}

As mentioned in the above answer, by updating the bashrc file you can run the pycharm.sh from anywhere on the linux terminal.
But if you love the icon and wants the Desktop shortcuts for the Pycharm on Ubuntu OS then follow the Below steps,
Quick way to create Pycharm launcher.
1. Start Pycharm using the pycharm.sh cmd from anywhere on the terminal or start the pycharm.sh located under bin folder of the pycharm artifact.
2. Once the Pycharm application loads, navigate to tools menu and select “Create Desktop Entry..”
3. Check the box if you want the launcher for all users.
4. If you Check the box i.e “Create entry for all users”, you will be asked for your password.
5. A message should appear informing you that it was successful.
6. Now Restart Pycharm application and you will find Pycharm in Unity dash and Application launcher.."
you should add python to your PATH during installation of python...after installation.. open cmd prompt type command-pip install nltk
then go to IDLE and open a new file..save it as file.py..then open file.py
type the following:
import nltk
nltk.download()
You can either
fig, ax = plt.subplots() #create figure and axes
candlestick(ax, quotes, ...)
or
candlestick(plt.gca(), quotes) #get the axis when calling the function
The first gives you more flexibility. The second is much easier if candlestick is the only thing you want to plot
Try this code:
preg_match('/[a-zA-Z]+<\/a>.$/', $lastgame, $match);
print_r($match);
Using /
as a delimiter means you also need to escape it here, like so: <\/a>.
UPDATE
preg_match('/<a.*<a.*>(.*)</', $lastgame, $match);
echo'['.$match[1].']';
Might not be the best way...

From experience I'll just note that while it is the C++ way to put formerly-static functions into the anonymous namespace, older compilers can sometimes have problems with this. I currently work with a few compilers for our target platforms, and the more modern Linux compiler is fine with placing functions into the anonymous namespace.
But an older compiler running on Solaris, which we are wed to until an unspecified future release, will sometimes accept it, and other times flag it as an error. The error is not what worries me, it's what it might be doing when it accepts it. So until we go modern across the board, we are still using static (usually class-scoped) functions where we'd prefer the anonymous namespace.
Having just messed around with this, it's useful to kjnow that the e.X / e.Y points are relative to the control, so if (as I was) you are adding a context menu to a listview or something similar, you will want to adjust it with the form's origin. In the example below I've added 20 to the x/y so that the menu appears slightly to the right and under the cursor.
cmDelete.Show(this, new Point(e.X + ((Control)sender).Left+20, e.Y + ((Control)sender).Top+20));

I had the same error for the MediaStream. The solution is set a stream to the srcObject.
From the docs:
Important: If you still have code that relies on createObjectURL() to attach streams to media elements, you need to update your code to simply set srcObject to the MediaStream directly.
You could do it with a static import and a helper class
nb the generification of this class could probably be improved
public class Lists {
private Lists() { } // can't be instantiated
public static List<T> join(List<T>... lists) {
List<T> result = new ArrayList<T>();
for(List<T> list : lists) {
result.addAll(list);
}
return results;
}
}
Then you can do things like
import static Lists.join;
List<T> result = join(list1, list2, list3, list4);
Use a struct when you want value semantics as opposed to reference semantics.
Not sure why folks are downvoting this but this is a valid point, and was made before the op clarified his question, and it is the most fundamental basic reason for a struct.
If you need reference semantics you need a class not a struct.
In Android Studio, if you open the Design window for the app, there is error message about Gradle being not synched properly. Next to the error, there is a 'Try Again' button. If you click on that, Android studio tries to sycn up again.
That worked for me.
int i = 25;
NSString *myString = [NSString stringWithFormat:@"%d",i];
This is one of many ways.
There is a possible way to avoid a if-branch in the loop.
s.append("[ "); // there is a space after the left bracket
for (i = 0; i < 5; ++i) {
s.appendF("\"%d\",", i); // always add comma
}
s.back() = ']'; // modify last comma (or the space) to right bracket
Alternatively, if you want to specify expected parameters in action signature, but pass them as arbitrary GET
arguments. Use filters, for example:
Create a route without parameters:
$Route::get('/history', ['uses'=>'ExampleController@history']);
Specify action with two parameters and attach the filter:
class ExampleController extends BaseController
{
public function __construct($browser)
{
$this->beforeFilter('filterDates', array(
'only' => array('history')
));
}
public function history($fromDate, $toDate)
{
/* ... */
}
}
Filter that translates GET
into action's arguments :
Route::filter('filterDates', function($route, Request $request) {
$notSpecified = '_';
$fromDate = $request->get('fromDate', $notSpecified);
$toDate = $request->get('toDate', $notSpecified);
$route->setParameter('fromDate', $fromDate);
$route->setParameter('toDate', $toDate);
});
use return
in the if condition will returns you out from the function,
so that you can use return to break the the if condition.
Try System.getProperty( "line.separator" )
writer.write(System.getProperty( "line.separator" ));
Trying to calculate the header and footer is bad :( A design should be simple, self explanatory. Plain easy. Calculations are just...not easy. Not easy for human and a bit hard on machines.
What you're looking for is a subset of the Holy Grail design.
Here's an implementation using the flex display. It includes side bars in addition to the footer and header. Enjoy:
<!DOCTYPE html>
<html style="height: 100%">
<head>
<meta charset=utf-8 />
<title>Holy Grail</title>
<!-- Reset browser defaults -->
<link rel="stylesheet" href="reset.css">
</head>
<body style="display: flex; height: 100%; flex-direction: column">
<div>HEADER<br/>------------
</div>
<!-- No need for 'flex-direction: row' because it's the default value -->
<div style="display: flex; flex: 1">
<div>NAV|</div>
<div style="flex: 1; overflow: auto">
CONTENT - START<br/>
<script>
for (var i=0 ; i<1000 ; ++i) {
document.write(" Very long content!");
}
</script>
<br/>CONTENT - END
</div>
<div>|SIDE</div>
</div>
<div>------------<br/>FOOTER</div>
</body>
</html>
You should place Scanner input = new Scanner (System.in);
into the main method rather than creating the input object outside.
To position horizontally center you can say width: 50%; margin: auto;
. As far as I know, that's cross browser. For vertical alignment you can try vertical-align:middle;
, but it may only work in relation to text. It's worth a try though.
There are a lot of good answers here, but I only want to add one thing. It sometimes happens that you want to scroll your ScrollView to a specific view of the layout, instead of a full scroll to the top or the bottom.
A simple example: in a registration form, if the user tap the "Signup" button when a edit text of the form is not filled, you want to scroll to that specific edit text to tell the user that he must fill that field.
In that case, you can do something like that:
scrollView.post(new Runnable() {
public void run() {
scrollView.scrollTo(0, editText.getBottom());
}
});
or, if you want a smooth scroll instead of an instant scroll:
scrollView.post(new Runnable() {
public void run() {
scrollView.smoothScrollTo(0, editText.getBottom());
}
});
Obviously you can use any type of view instead of Edit Text. Note that getBottom() returns the coordinates of the view based on its parent layout, so all the views used inside the ScrollView should have only a parent (for example a Linear Layout).
If you have multiple parents inside the child of the ScrollView, the only solution i've found is to call requestChildFocus on the parent view:
editText.getParent().requestChildFocus(editText, editText);
but in this case you cannot have a smooth scroll.
I hope this answer can help someone with the same problem.
string today = DateTime.Today.ToString("M/d");
1) Create a handler in the fragment that you want to update.
public static Handler sUpdateHandler;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
sUpdateHandler = new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
// call you update method here.
}
};
}
2) In the Activity/Fragment/Dialog, wherever you want the update call to be fired, get the reference to that handler and send a message (telling your fragment to update)
// Check if the fragment is visible by checking if the handler is null or not.
Handler handler = TaskTabCompletedFragment.sUpdateHandler;
if (handler != null) {
handler.obtainMessage().sendToTarget();
}
Apparently anonymous functions cannot be serialized.
Example
$function = function () {
return "ABC";
};
serialize($function); // would throw error
From your code you are using Closure:
$callback = function () // <---------------------- Issue
{
return 'ZendMail_' . microtime(true) . '.tmp';
};
Solution 1 : Replace with a normal function
Example
function emailCallback() {
return 'ZendMail_' . microtime(true) . '.tmp';
}
$callback = "emailCallback" ;
Solution 2 : Indirect method call by array variable
If you look at http://docs.mnkras.com/libraries_23rdparty_2_zend_2_mail_2_transport_2file_8php_source.html
public function __construct($options = null)
63 {
64 if ($options instanceof Zend_Config) {
65 $options = $options->toArray();
66 } elseif (!is_array($options)) {
67 $options = array();
68 }
69
70 // Making sure we have some defaults to work with
71 if (!isset($options['path'])) {
72 $options['path'] = sys_get_temp_dir();
73 }
74 if (!isset($options['callback'])) {
75 $options['callback'] = array($this, 'defaultCallback'); <- here
76 }
77
78 $this->setOptions($options);
79 }
You can use the same approach to send the callback
$callback = array($this,"aMethodInYourClass");
