If you are looking for a library to carry out client-side image compression, you can check this out:compress.js. This will basically help you compress multiple images purely with JavaScript and convert them to base64 string. You can optionally set the maximum size in MB and also the preferred image quality.
For Formatting in mm-dd-yyyy
aa=date.split("-")
date=aa[1]+'-'+aa[2]+'-'+aa[0]
public class MainActivity extends Activity {
ImageView imgV;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imgV= (ImageView) findViewById("your Image View Id");
imgV.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
imgV.setScaleType(ScaleType.FIT_XY);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
getSupportActionBar().hide();
}
}
});
}
}
A good answer for me was to install libtool:
sudo apt-get install libtool
You could use this:
a = ((4.0, 4, 4.0), (3.0, 3, 3.6), (3.5, 6, 4.8))
a = np.array(a)
a[:,0]
returns >>> array([4. , 3. , 3.5])
Generally it means that you are providing an index for which a list element does not exist.
E.g, if your list was [1, 3, 5, 7]
, and you asked for the element at index 10, you would be well out of bounds and receive an error, as only elements 0 through 3 exist.
Below is the code that read the data from the text file and sends it to the handler for processing and receive the response data from the handler and read it and store the data in the string builder class
//Get the data from text file that needs to be sent.
FileStream fileStream = new FileStream(@"G:\Papertest.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite);
byte[] buffer = new byte[fileStream.Length];
int count = fileStream.Read(buffer, 0, buffer.Length);
//This is a handler would recieve the data and process it and sends back response.
WebRequest myWebRequest = WebRequest.Create(@"http://localhost/Provider/ProcessorHandler.ashx");
myWebRequest.ContentLength = buffer.Length;
myWebRequest.ContentType = "application/octet-stream";
myWebRequest.Method = "POST";
// get the stream object that holds request stream.
Stream stream = myWebRequest.GetRequestStream();
stream.Write(buffer, 0, buffer.Length);
stream.Close();
//Sends a web request and wait for response.
try
{
WebResponse webResponse = myWebRequest.GetResponse();
//get Stream Data from the response
Stream respData = webResponse.GetResponseStream();
//read the response from stream.
StreamReader streamReader = new StreamReader(respData);
string name;
StringBuilder str = new StringBuilder();
while ((name = streamReader.ReadLine()) != null)
{
str.Append(name); // Add to stringbuider when response contains multple lines data
}
}
catch (Exception ex)
{
throw ex;

I often use git reset --mixed to revert a base version before multiple commits which you want to merge, then I make a new commit, that way could let your commit newest, assure your version is HEAD after you push to server.

Author: Ralph <[email protected]>
Date: Thu Jun 13 16:44:12 2013 -0700
Fixed a bug in space world automation
If I want to merge head two commits into one, first I use :
git reset --mixed 249cf9392da197573a17c8426c282
"249cf9392da197573a17c8426c282" was third version, also is your base version before you merge, after that, I make a new commit :
git add .
git commit -m 'some commit message'
It's all, hope is another way for everybody.
FYI, from git reset --help
:
--mixed
Resets the index but not the working tree (i.e., the changed files are
preserved but not marked for commit) and reports what has not been
updated. This is the default action.
This my be helpful!!!

$blog is an object, not an array, so you should access it like so:

I was having troubles understanding an applying the accepted answer. I needed a little more context. Now that I have figured it out, here is a full example:

public class MainActivity extends AppCompatActivity {
Button myButton;
View myView;
boolean isUp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myView = findViewById(R.id.my_view);
myButton = findViewById(R.id.my_button);
// initialize as invisible (could also do in xml)
myView.setVisibility(View.INVISIBLE);
myButton.setText("Slide up");
isUp = false;
}
// slide the view from below itself to the current position
public void slideUp(View view){
view.setVisibility(View.VISIBLE);
TranslateAnimation animate = new TranslateAnimation(
0, // fromXDelta
0, // toXDelta
view.getHeight(), // fromYDelta
0); // toYDelta
animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
}
// slide the view from its current position to below itself
public void slideDown(View view){
TranslateAnimation animate = new TranslateAnimation(
0, // fromXDelta
0, // toXDelta
0, // fromYDelta
view.getHeight()); // toYDelta
animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
}
public void onSlideViewButtonClick(View view) {
if (isUp) {
slideDown(myView);

.=counta(range)
counta
: "Returns a count of the number of values in a dataset"
Note: CountA
considers ""
to be a value. Only cells that are blank (press delete in a cell to blank it) are not counted.
Google support: https://support.google.com/docs/answer/3093991
countblank
: "Returns the number of empty cells in a given range"
Note: CountBlank
considers both blank cells (press delete to blank a cell) and cells that have a formula that returns ""
to be empty cells.
Google Support: https://support.google.com/docs/answer/3093403
If you have a range that includes formulae that result in ""
, then you can modify your formula from
=counta(range)
to:
=Counta(range) - Countblank(range)
EDIT: the function is countblank
, not countblanks
, the latter will give an error.
In the repository root, the .git/config
file holds all information about remote repositories and branches. In your example, you should look for something like:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = server:gitRepo.git
Also, the Git command git remote -v
shows the remote repository name and URL. The "origin" remote repository usually corresponds to the original repository, from which the local copy was cloned.
Can someone help me with the exact syntax?
It's a three-step process, and it involves modifying the openssl.cnf
file. You might be able to do it with only command line options, but I don't do it that way.
Find your openssl.cnf
file. It is likely located in /usr/lib/ssl/openssl.cnf
:
$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf
On my Debian system, /usr/lib/ssl/openssl.cnf
is used by the built-in openssl
program. On recent Debian systems it is located at /etc/ssl/openssl.cnf
You can determine which openssl.cnf
is being used by adding a spurious XXX
to the file and see if openssl
chokes.
First, modify the req
parameters. Add an alternate_names
section to openssl.cnf
with the names you want to use. There are no existing alternate_names
sections, so it does not matter where you add it.
[ alternate_names ]
DNS.1 = example.com
DNS.2 = www.example.com
DNS.3 = mail.example.com
DNS.4 = ftp.example.com
Next, add the following to the existing [ v3_ca ]
section. Search for the exact string [ v3_ca ]
:
subjectAltName = @alternate_names
You might change keyUsage
to the following under [ v3_ca ]
:
keyUsage = digitalSignature, keyEncipherment
digitalSignature
and keyEncipherment
are standard fare for a server certificate. Don't worry about nonRepudiation
. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.
In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.
Second, modify the signing parameters. Find this line under the CA_default
section:
# Extension copying option: use with caution.
# copy_extensions = copy
And change it to:
# Extension copying option: use with caution.
copy_extensions = copy
This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.
Third, generate your self-signed certificate:
$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...
Finally, examine the certificate:
$ openssl x509 -in certificate.pem -text -noout

A space in a CSS selector selects child elements.
.btn input
This is basically what you wrote and it would select <input>
elements within any element that has the btn
class.
I think you're looking for
input[disabled].btn:hover, input[disabled].btn:active, input[disabled].btn:focus
This would select <input>
elements with the disabled
attribute and the btn
class in the three different states of hover
, active
and focus
.

I noticed one error in Dave Ward's answer (perhaps a recent change?):
The query string paramaters are in request.query
, not request.params
. (See https://stackoverflow.com/a/6913287/166530 )
request.params
by default is filled with the value of any "component matches" in routes, i.e.
app.get('/user/:id', function(request, response){
response.send('user ' + request.params.id);
});
and, if you have configured express to use its bodyparser (app.use(express.bodyParser());
) also with POST'ed formdata. (See How to retrieve POST query parameters? )
The closest equivalent to Java's toString
is to implement __str__
for your class. Put this in your class definition:
def __str__(self):
return "foo"
You may also want to implement __repr__
to aid in debugging.
See here for more information:
Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..
FROM TABLE A
The other way is
FROM (SELECT col as name1, col2 as name2 FROM ...) B
Notice that the select clause and the parentheses around it are a table, a virtual table.
So, using your second code example (I am guessing at the columns you are hoping to retrieve here):
SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
Notice that your real table attribute
is the first table in this join, and that this virtual table I've called b
is the second table.
This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.
SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
SELECT count(*) AS langcount, at.attribute
FROM attributeTranslation at
GROUP BY at.attribute
) c ON (a.id = c.attribute)
See how that goes? You've generated a virtual table c
containing two columns, joined it to the other two, used one of the columns for the ON
clause, and returned the other as a column in your result set.
If you are looking for the contents of the TD (cell), then it would simply be: col.innerHTML
I.e: alert(col.innerHTML);
You'll then need to parse that for any values you're looking for.
Python’s raw strings are just a way to tell the Python interpreter that it should interpret backslashes as literal slashes. If you read strings entered by the user, they are already past the point where they could have been raw. Also, user input is most likely read in literally, i.e. “raw”.
This means the interpreting happens somewhere else. But if you know that it happens, why not escape the backslashes for whatever is interpreting it?
s = s.replace("\\", "\\\\")
(Note that you can't do r"\"
as “a raw string cannot end in a single backslash”, but I could have used r"\\"
as well for the second argument.)
If that doesn’t work, your user input is for some arcane reason interpreting the backslashes, so you’ll need a way to tell it to stop that.
To get the type, use the builtin type
function. With the in
operator, you can test if the type is a numpy type by checking if it contains the string numpy
;
In [1]: import numpy as np
In [2]: a = np.array([1, 2, 3])
In [3]: type(a)
Out[3]: <type 'numpy.ndarray'>
In [4]: 'numpy' in str(type(a))
Out[4]: True
(This example was run in IPython, by the way. Very handy for interactive use and quick tests.)
echo $PWD
PWD is an environment variable.
I struggled with both these approaches for more complex queries than those shown, because the subquery approach was horribly ineficient no matter what indexes I put on, and because I couldn't get the outer self-join through Hibernate
The best (and easiest) way to do this is to group by something which is constructed to contain a concatenation of the fields you require and then to pull them out using expressions in the SELECT clause. If you need to do a MAX() make sure that the field you want to MAX() over is always at the most significant end of the concatenated entity.
The key to understanding this is that the query can only make sense if these other fields are invariant for any entity which satisfies the Max(), so in terms of the sort the other pieces of the concatenation can be ignored. It explains how to do this at the very bottom of this link. http://dev.mysql.com/doc/refman/5.0/en/group-by-hidden-columns.html
If you can get am insert/update event (like a trigger) to pre-compute the concatenation of the fields you can index it and the query will be as fast as if the group by was over just the field you actually wanted to MAX(). You can even use it to get the maximum of multiple fields. I use it to do queries against multi-dimensional trees expresssed as nested sets.
It looks like this issue has to do with the difference between the Content-Type
and Accept
headers. In HTTP, Content-Type
is used in request and response payloads to convey the media type of the current payload. Accept
is used in request payloads to say what media types the server may use in the response payload.
So, having a Content-Type
in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type
does matter.
If a server is not able to process the Content-Type
of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept
header, it will return a 406 error.)
In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.
You could fix this in one of two ways:
Include the DataServiceVersion header in the request and set it be less than v3. For example:
DataServiceVersion: 2.0;
(Option 2 assumes that you aren't using any v3 features in your request payload.)
This will get you the timezone as a PHP variable. I wrote a function using jQuery and PHP. This is tested, and does work!
On the PHP page where you are want to have the timezone as a variable, have this snippet of code somewhere near the top of the page:
<?php
session_start();
$timezone = $_SESSION['time'];
?>
This will read the session variable "time", which we are now about to create.
On the same page, in the <head>
section, first of all you need to include jQuery:
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
Also in the <head>
section, paste this jQuery:
<script type="text/javascript">
$(document).ready(function() {
if("<?php echo $timezone; ?>".length==0){
var visitortime = new Date();
var visitortimezone = "GMT " + -visitortime.getTimezoneOffset()/60;
$.ajax({
type: "GET",
url: "http://example.com/timezone.php",
data: 'time='+ visitortimezone,
success: function(){
location.reload();
}
});
}
});
</script>
You may or may not have noticed, but you need to change the url to your actual domain.
One last thing. You are probably wondering what the heck timezone.php is. Well, it is simply this: (create a new file called timezone.php and point to it with the above url)
<?php
session_start();
$_SESSION['time'] = $_GET['time'];
?>
If this works correctly, it will first load the page, execute the JavaScript, and reload the page. You will then be able to read the $timezone variable and use it to your pleasure! It returns the current UTC/GMT time zone offset (GMT -7) or whatever timezone you are in.

Encoding.GetString Method (Byte[]) convert bytes to a string.
When overridden in a derived class, decodes all the bytes in the specified byte array into a string.
Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)
Syntax
public virtual string GetString(byte[] bytes)
Parameters
bytes
Type: System.Byte[]
The byte array containing the sequence of bytes to decode.
Return Value
Type: System.String
A String containing the results of decoding the specified sequence of bytes.
Exceptions
ArgumentException - The byte array contains invalid Unicode code points.
ArgumentNullException - bytes is null.
DecoderFallbackException - A fallback occurred (see Character Encoding in the .NET Framework for complete explanation) or DecoderFallback is set to DecoderExceptionFallback.
Remarks
If the data to be converted is available only in sequential blocks (such as data read from a stream) or if the amount of data is so large that it needs to be divided into smaller blocks, the application should use the Decoder or the Encoder provided by the GetDecoder method or the GetEncoder method, respectively, of a derived class.
See the Remarks under Encoding.GetChars for more discussion of decoding techniques and considerations.
As far as you're concerned once you've "pulled out" the contents with something like .html() it's just a string. You can test that with
<html>
<head>
<title>runthis</title>
<script type="text/javascript" language="javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">
$(document).ready( function() {
var x = $("#foo").html();
alert( typeof(x) );
});
</script>
</head>
<body>
<div id="foo"><table><tr><td>x</td></tr></table><span>xyz</span></div>
</body>
</html>
The alert text is string. As long as you don't pass it to a parser there's no magic about it, it's a string like any other string.
There's nothing that hinders you from using .post() to send this string back to the server.
edit: Don't pass a string as the parameter data to .post() but an object, like
var data = {
id: currid,
html: div_html
};
$.post("http://...", data, ...);
jquery will handle the encoding of the parameters.
If you (for whatever reason) want to keep your string you have to encode the values with something like escape().
var data = 'id='+ escape(currid) +'&html='+ escape(div_html);
This is what I've been using. Haven't seen any issues.
destroy: function(){
this.remove();
this.unbind();
}
I had trouble changing the text color as well - I never saw the color change.
Until I added the code to change the text color to the event DataBindingsComplete
for DataGridView
. After that it worked.
I hope this will help people who face the same problem.
vbCrLf
is a relic of Visual Basic 6 days. Though it works exactly the same as Environment.NewLine
, it has only been kept to make the .NET api feel more familiar to VB6 developers switching.
You can call the String.Replace() function to avoid concatenation of many single string values.
MsgBox ("first line \n second line.".Replace("\n", Environment.NewLine))
Ctrl + Alt + Shift + N allows you to search for symbols, including methods.
The primary advantage of this more complicated keybinding is that is searches in all files, not just the current file as Ctrl + F12 does.
(And as always, for Mac you substitute Cmd for Ctrl for these keybindings.)
Usually you can double click the .py
file in Windows explorer to run it. If this doesn't work, you can create a batch file in the same directory with the following contents:
C:\python23\python YOURSCRIPTNAME.py
Then double click that batch file. Or, you can simply run that line in the command prompt while your working directory is the location of your script.
For me, my problem was I needed to navigate back and then transition to another state. So using $window.history.back()
didn't work because for some reason the transition happened before history.back() occured so I had to wrap my transition in a timeout function like so.
$window.history.back();
setTimeout(function() {
$state.transitionTo("tab.jobs"); }, 100);
This fixed my issue.
Correct way of embedding images into Outlook and avoiding security problems is the next:
Do not access properties via getters or you will get security warnings on some machines.

mail.SaveSentMessageFolder = folder;
mail.Subject = "Hi Everyone";

I got same error message. I was giving

Instead of

The best flexible solution with .net built-in function called- char.IsDigit
. It works with unlimited long numbers. It will only return true if each character is a numeric number. I used it lot of times with no issues and much easily cleaner solution I ever found. I made a example method.Its ready to use. In addition I added validation for null and empty input. So the method is now totally bulletproof
public static bool IsNumeric(string strNumber)
{
if (string.IsNullOrEmpty(strNumber))
{
return false;
}
else
{
int numberOfChar = strNumber.Count();
if (numberOfChar > 0)
{
bool r = strNumber.All(char.IsDigit);
return r;
}
else
{
return false;
}
}
}
As Carlos Rincones suggested; don't be affraid of playing with superglobals.
$files = $_FILES;
for($i=0; $i<count($files['userfile']['name']); $i++)
{
$_FILES = array();
foreach( $files['userfile'] as $k=>$v )
{
$_FILES['userfile'][$k] = $v[$i];
}
$this->upload->do_upload('userfile')
}
int.TryPasrse() Methode is the best way so if the value was string you will never have an exception , instead of the TryParse Methode return to you bool value so you will know if the parse operation succeeded or failed
string yourText = "2";
int num;
bool res = int.TryParse(yourText, out num);
if (res == true)
{
// the operation succeeded and you got the number in num parameter
}
else
{
// the operation failed
}
This might help

You need to output ANSI colour codes. Note that not all terminals support this; if colour sequences are not supported, garbage will show up.
Example:
cout << "\033[1;31mbold red text\033[0m\n";
Here, \033
is the ESC character, ASCII 27. It is followed by [
, then zero or more numbers separated by ;
, and finally the letter m
. The numbers describe the colour and format to switch to from that point onwards.
The codes for foreground and background colours are:
foreground background
black 30 40
red 31 41
green 32 42
yellow 33 43
blue 34 44
magenta 35 45
cyan 36 46
white 37 47
Additionally, you can use these:
reset 0 (everything back to normal)
bold/bright 1 (often a brighter shade of the same colour)
underline 4
inverse 7 (swap foreground and background colours)
bold/bright off 21
underline off 24
inverse off 27
See the table on Wikipedia for other, less widely supported codes.
To determine whether your terminal supports colour sequences, read the value of the TERM
environment variable. It should specify the particular terminal type used (e.g. vt100
, gnome-terminal
, xterm
, screen
, ...). Then look that up in the terminfo database; check the colors
capability.
I prefer to use nvidia-smi to monitor GPU usage. if it goes up significantly when you start you program, it's a strong sign that your tensorflow is using GPU.
std::move
?A: std::move()
is a function from the C++ Standard Library for casting to a rvalue reference.
Simplisticly std::move(t)
is equivalent to:
static_cast<T&&>(t);
An rvalue is a temporary that does not persist beyond the expression that defines it, such as an intermediate function result which is never stored in a variable.
int a = 3; // 3 is a rvalue, does not exist after expression is evaluated
int b = a; // a is a lvalue, keeps existing after expression is evaluated
An implementation for std::move() is given in N2027: "A Brief Introduction to Rvalue References" as follows:
template <class T>
typename remove_reference<T>::type&&
std::move(T&& a)
{
return a;
}
As you can see, std::move
returns T&&
no matter if called with a value (T
), reference type (T&
), or rvalue reference (T&&
).
A: As a cast, it does not do anything during runtime. It is only relevant at compile time to tell the compiler that you would like to continue considering the reference as an rvalue.
foo(3 * 5); // obviously, you are calling foo with a temporary (rvalue)
int a = 3 * 5;
foo(a); // how to tell the compiler to treat `a` as an rvalue?
foo(std::move(a)); // will call `foo(int&& a)` rather than `foo(int a)` or `foo(int& a)`
What it does not do:
A: You should use std::move
if you want to call functions that support move semantics with an argument which is not an rvalue (temporary expression).
This begs the following follow-up questions for me:
What is move semantics? Move semantics in contrast to copy semantics is a programming technique in which the members of an object are initialized by 'taking over' instead of copying another object's members. Such 'take over' makes only sense with pointers and resource handles, which can be cheaply transferred by copying the pointer or integer handle rather than the underlying data.
What kind of classes and objects support move semantics? It is up to you as a developer to implement move semantics in your own classes if these would benefit from transferring their members instead of copying them. Once you implement move semantics, you will directly benefit from work from many library programmers who have added support for handling classes with move semantics efficiently.
Why can't the compiler figure it out on its own? The compiler cannot just call another overload of a function unless you say so. You must help the compiler choose whether the regular or move version of the function should be called.
In which situations would I want to tell the compiler that it should treat a variable as an rvalue? This will most likely happen in template or library functions, where you know that an intermediate result could be salvaged.
(at least) for Django 1.8:
If you use
if settings.DEBUG:
urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))
as described above, make sure that no "catch all" url pattern, directing to a default view, comes before that in urlpatterns = []. As .append will put the added scheme to the end of the list, it will of course only be tested if no previous url pattern matches. You can avoid that by using something like this where the "catch all" url pattern is added at the very end, independent from the if statement:
if settings.DEBUG:
urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))
urlpatterns.append(url(r'$', 'views.home', name='home')),
Pure JavaScript:
var button = document.getElementById('button'); // Assumes element with id='button'
button.onclick = function() {
var div = document.getElementById('newpost');
if (div.style.display !== 'none') {
div.style.display = 'none';
}
else {
div.style.display = 'block';
}
};
jQuery:
$("#button").click(function() {
// assumes element with id='button'
$("#newpost").toggle();
});
if (isset($_POST('sms_code') == TRUE ) {
change this line to
if (isset($_POST['sms_code']) == TRUE ) {
You are using parentheseis () for $_POST
but you wanted square brackets []
:)
OR
if (isset($_POST['sms_code']) && $_POST['sms_code']) {
//this lets in this block only if $_POST['sms_code'] has some value

ASCII just defines a 7 bit code page with 128 symbols. ANSI extends this to 8 bit and there are several different code pages for the symbols 128 to 255.
The naming ANSI is not correct because it is actually the ISO/IEC 8859 norm that defines this code pages. See ISO/IEC 8859 for reference. There are 16 code pages ISO/IEC 8859-1 to ISO/IEC 8859-16.
Windows-1252 is again based on ISO/IEC 8859-1 with some modification mainly in the range of the C1 control set in the range 128 to 159. Wikipedia states that Windows-1252 is also refered as ISO-8859-1 with a second hyphen between ISO and 8859. (Unbelievable! Who does something like that?!?)
Here is the answer for those of you looking like I did all over the web trying to find out how to do this task. Uploading a photo to a server with the file name stored in a mysql database and other form data you want in your Database. Please let me know if it helped.
Firstly the form you need:
<form method="post" action="addMember.php" enctype="multipart/form-data">
<p>
Please Enter the Band Members Name.
</p>
<p>
Band Member or Affiliates Name:
</p>
<input type="text" name="nameMember"/>
<p>
Please Enter the Band Members Position. Example:Drums.
</p>
<p>
Band Position:
</p>
<input type="text" name="bandMember"/>
<p>
Please Upload a Photo of the Member in gif or jpeg format. The file name should be named after the Members name. If the same file name is uploaded twice it will be overwritten! Maxium size of File is 35kb.
</p>
<p>
Photo:
</p>
<input type="hidden" name="size" value="350000">
<input type="file" name="photo">
<p>
Please Enter any other information about the band member here.
</p>
<p>
Other Member Information:
</p>
<textarea rows="10" cols="35" name="aboutMember">
</textarea>
<p>
Please Enter any other Bands the Member has been in.
</p>
<p>
Other Bands:
</p>
<input type="text" name="otherBands" size=30 />
<br/>
<br/>
<input TYPE="submit" name="upload" title="Add data to the Database" value="Add Member"/>
</form>
Then this code processes you data from the form:
<?php
// This is the directory where images will be saved
$target = "your directory";
$target = $target . basename( $_FILES['photo']['name']);
// This gets all the other information from the form
$name=$_POST['nameMember'];
$bandMember=$_POST['bandMember'];
$pic=($_FILES['photo']['name']);
$about=$_POST['aboutMember'];
$bands=$_POST['otherBands'];
// Connects to your Database
mysqli_connect("yourhost", "username", "password") or die(mysqli_error()) ;
mysqli_select_db("dbName") or die(mysqli_error()) ;
// Writes the information to the database
mysqli_query("INSERT INTO tableName (nameMember,bandMember,photo,aboutMember,otherBands)
VALUES ('$name', '$bandMember', '$pic', '$about', '$bands')") ;
// Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{
// Tells you if its all ok
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory";
}
else {
// Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>

Not exactly an answer to the quoting/escaping problem of the original question but probably something that would actually have been more useful for the op:
unset FILES
for f in 2011-*.jpg; do FILES+=("$f"); done
echo "${FILES[@]}"
Where of course the expression would have to be adopted to the specific requirement (e.g. *.jpg
for all or 2001-09-11*.jpg
for only the pictures of a certain day).
The server may need read permission for your home directory and .htaccess therein
The simplest way to do this is through Visual Studio's object explorer, which is also supported in the Community edition.
Once you have made a connection to SQL server, browse to the type, right click and select View Code, make your changes to the schema of the user defined type and click update. Visual Studio should show you all of the dependencies for that object and generate scripts to update the type and recompile dependencies.
I am having random issues with the latest AndroidStudio (3.2 B1) and tried all the solutions above. I got it working by disabling the "Zip Align Enabled" option in "Build Types"
The Following command displays extra informations
curl -X POST http://httpbin.org/post -v > /dev/null
You can ask server to send just HEAD, instead of full response
curl -X HEAD -I http://httpbin.org/
Note:
In some cases, server may send different headers for POST and HEAD. But in almost all cases headers are same.
jQuery.trim() works well.
You can use virtualenvwrapper
in order to ease the way you work with virtualenv
.
Installing virtualenvwrapper
:
pip install virtualenvwrapper
If you are using a standard shell, open your ~/.bashrc
or ~/.zshrc
if you use Oh My Zsh. Add these two lines:
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
To activate an existing virtualenv, use command workon
:
$ workon myenv
(myenv)$
In order to deactivate your virtualenv:
(myenv)$ deactivate
Here is my tutorial, step by step on how to install virtualenv and virtualenvwrapper.
Just run the main
method which is in the class SampleWebJspApplication
.
Spring Boot will take care of all the rest (starting the embedded tomcat which will host your sample application).
I prefer to avoid using Ajax.BeginForm
helper and do an Ajax call with JQuery. In my experience it is easier to maintain code written like this. So below are the details:
Models
public class ManagePeopleModel
{
public List<PersonModel> People { get; set; }
... any other properties
}
public class PersonModel
{
public int Id { get; set; }
public string Name { get; set; }
public int Age { get; set; }
... any other properties
}
Parent View
This view contains the following things:
@model ManagePeopleModel
<h1>Manage People</h1>
@using(var table = Html.Bootstrap().Begin(new Table()))
{
foreach(var person in Model.People)
{
<tr>
<td>@person.Id</td>
<td>@Person.Name</td>
<td>@person.Age</td>
<td>@html.Bootstrap().Button().Text("Edit Person").Data(new { @id = person.Id }).Class("btn-trigger-modal")</td>
</tr>
}
}
@using (var m = Html.Bootstrap().Begin(new Modal().Id("modal-person")))
{
}
@section Scripts
{
<script type="text/javascript">
// Handle "Edit Person" button click.
// This will make an ajax call, get information for person,
// put it all in the modal and display it
$(document).on('click', '.btn-trigger-modal', function(){
var personId = $(this).data('id');
$.ajax({
url: '/[WhateverControllerName]/GetPersonInfo',
type: 'GET',
data: { id: personId },
success: function(data){
var m = $('#modal-person');
m.find('.modal-content').html(data);
m.modal('show');
}
});
});
// Handle submitting of new information for Person.
// This will attempt to save new info
// If save was successful, it will close the Modal and reload page to see updated info
// Otherwise it will only reload contents of the Modal
$(document).on('click', '#btn-person-submit', function() {
var self = $(this);
$.ajax({
url: '/[WhateverControllerName]/UpdatePersonInfo',
type: 'POST',
data: self.closest('form').serialize(),
success: function(data) {
if(data.success == true) {
$('#modal-person').modal('hide');
location.reload(false)
} else {
$('#modal-person').html(data);
}
}
});
});
</script>
}
Partial View
This view contains a modal that will be populated with information about person.
@model PersonModel
@{
// get modal helper
var modal = Html.Bootstrap().Misc().GetBuilderFor(new Modal());
}
@modal.Header("Edit Person")
@using (var f = Html.Bootstrap.Begin(new Form()))
{
using (modal.BeginBody())
{
@Html.HiddenFor(x => x.Id)
@f.ControlGroup().TextBoxFor(x => x.Name)
@f.ControlGroup().TextBoxFor(x => x.Age)
}
using (modal.BeginFooter())
{
// if needed, add here @Html.Bootstrap().ValidationSummary()
@:@Html.Bootstrap().Button().Text("Save").Id("btn-person-submit")
@Html.Bootstrap().Button().Text("Close").Data(new { dismiss = "modal" })
}
}
Controller Actions
public ActionResult GetPersonInfo(int id)
{
var model = db.GetPerson(id); // get your person however you need
return PartialView("[Partial View Name]", model)
}
public ActionResult UpdatePersonInfo(PersonModel model)
{
if(ModelState.IsValid)
{
db.UpdatePerson(model); // update person however you need
return Json(new { success = true });
}
// else
return PartialView("[Partial View Name]", model);
}
The answers above are good. Adding a case that I used. Just if you don't want to use numpy and keep it as list without changing the contents.
You can run a small loop and change the dimension from 1xN to Nx1.
tmp=[]
for b in bus:
tmp.append([b])
bus=tmp
It is maybe not efficient while in case of very large numbers. But it works for a small set of numbers. Thanks

I've encountered like this in Hybris.
1.2 If yes, then you need to change your properties in project.properties
1.3 Change your address, any available address. In my case, I changed from 8000 to 8080. then save.
java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8080,suspend=n yourServer
In your console, rebuild your ant using command 'ant all'
Then debug again, using the command 'hybrisserver.bat debug'
If you're trying to load a DataTable
, then leverage the SqlDataAdapter
instead:
DataTable dt = new DataTable();
using (SqlConnection c = new SqlConnection(cString))
using (SqlDataAdapter sda = new SqlDataAdapter(sql, c))
{
sda.SelectCommand.CommandType = CommandType.StoredProcedure;
sda.SelectCommand.Parameters.AddWithValue("@parm1", val1);
...
sda.Fill(dt);
}
You don't even need to define the columns. Just create the DataTable
and Fill
it.
Here, cString
is your connection string and sql
is the stored procedure command.
This worked for me:
git ls-files -m | xargs -L 1 chmod 644
You have to make sure the file is been saved with UTF-8 encoding.
You can do it with several plain text editors. With Notepad++, i.e., you can choose in the menu Encoding
-->Encode in UTF-8
. You can also do it even with Windows' Notepad (Save As
--> Encoding UTF-8).
If you are using Eclipse, you can set it in the file's Properties.
Also, check if the problem is that you have to escape those characters. It wouldn't be strange that were your problem, as one of the characters is &
.
In addition of all answers. You can also specify the minsdk to apply with this annotation
@TargetApi(_apiLevel_)
I used this in order to accept this request even my minsdk is 18. What it does is that the method only runs when device targets "_apilevel_" and upper. Here's my method:
@TargetApi(23)
void solicitarPermisos(){
if (ContextCompat.checkSelfPermission(this,permiso)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (shouldShowRequestPermissionRationale(
Manifest.permission.READ_EXTERNAL_STORAGE)) {
// Explain to the user why we need to read the contacts
}
requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
1);
// MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
// app-defined int constant that should be quite unique
return;
}
}
It is never possible. Constructor Overriding is never possible in Java.
This is because,
Constructor looks like a method but name should be as class name and no return value.
Overriding means what we have declared in Super class, that exactly we have to declare in Sub class it is called Overriding. Super class name and Sub class names are different.
If you trying to write Super class Constructor in Sub class, then Sub class will treat that as a method not constructor because name should not match with Sub class name. And it will give an compilation error that methods does not have return value. So we should declare as void, then only it will compile.
Have a look at the following code :
Class One
{
....
One() { // Super Class constructor
....
}
One(int a) { // Super Class Constructor Overloading
....
}
}
Class Two extends One
{
One() { // this is a method not constructor
..... // because name should not match with Class name
}
Two() { // sub class constructor
....
}
Two(int b) { // sub class constructor overloading
....
}
}
Addendum to @ideasman42's answer:
def saveAsPNG(array, filename):
import struct
if any([len(row) != len(array[0]) for row in array]):
raise ValueError, "Array should have elements of equal size"
#First row becomes top row of image.
flat = []; map(flat.extend, reversed(array))
#Big-endian, unsigned 32-byte integer.
buf = b''.join([struct.pack('>I', ((0xffFFff & i32)<<8)|(i32>>24) )
for i32 in flat]) #Rotate from ARGB to RGBA.
data = write_png(buf, len(array[0]), len(array))
f = open(filename, 'wb')
f.write(data)
f.close()
So you can do:
saveAsPNG([[0xffFF0000, 0xffFFFF00],
[0xff00aa77, 0xff333333]], 'test_grid.png')
Producing test_grid.png
:
(Transparency also works, by reducing the high byte from 0xff
.)
JSDoc 3 allows you to annotate your functions with the @access private
(previously the @private
tag) which is also useful for broadcasting your intent to other developers - http://usejsdoc.org/tags-access.html
Try this something like this:
var p_ids = document.forms[0].elements["p_id[]"];
alert(p_ids.length);
for (var i = 0, len = p_ids.length; i < len; i++) {
alert(p_ids[i].value);
}
You alread removed the active class from all the tabs but then you add the active class, again, to all the tabs. You should only add the active class to the currently selected tab like so http://jsfiddle.net/QFnRa/
$(".tab").removeClass("active");
$(this).addClass("active");
The return value can be used by the operating system to check how the program was closed.
Return value 0 usually means OK in most operating systems (the ones I can think of anyway).
It also can be checked when you call a process yourself, and see if the program exited and finished properly.
It's NOT just a programming convention.
To replace a string in multiple files you can use:
grep -rl string1 somedir/ | xargs sed -i 's/string1/string2/g'
E.g.
grep -rl 'windows' ./ | xargs sed -i 's/windows/linux/g'
You need to open the file in binary b
mode to take care of blank lines in Python 2. This isn't required in Python 3.
So, change open('test.csv', 'w')
to open('test.csv', 'wb')
.
bin\debug
foldermyservice.vshost.exe
to myservice.exe
(for fellow googlers, copied from duplicate question) This answer is outdated since text-decoration-color is now supported by most modern browsers.
You can do this via the following CSS rule as an example:
text-decoration-color:green
If this rule isn't supported by an older browser, you can use the following solution:
Setting your word with a border-bottom:
a:link {
color: red;
text-decoration: none;
border-bottom: 1px solid blue;
}
a:hover {
border-bottom-color: green;
}
I have a bash solution like mogsie but with heredoc instead of herestring to allow you to avoid escaping double quotes
eval "cat <<EOF
$(<template.txt)
EOF
" 2> /dev/null
Well, you could use
import re
list = re.sub(r'[.!,;?]', ' ', string).split()
Note that both string
and list
are names of builtin types, so you probably don't want to use those as your variable names.
I used pyplot
's axes
object to manually adjust the sizes without using GridSpec
:
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(0, 10, 0.2)
y = np.sin(x)
# definitions for the axes
left, width = 0.07, 0.65
bottom, height = 0.1, .8
bottom_h = left_h = left+width+0.02
rect_cones = [left, bottom, width, height]
rect_box = [left_h, bottom, 0.17, height]
fig = plt.figure()
cones = plt.axes(rect_cones)
box = plt.axes(rect_box)
cones.plot(x, y)
box.plot(y, x)
plt.show()
Maybe you can exploit a sample function like :
function strtotime(date, addTime){_x000D_
let generatedTime=date.getTime();_x000D_
if(addTime.seconds) generatedTime+=1000*addTime.seconds; //check for additional seconds _x000D_
if(addTime.minutes) generatedTime+=1000*60*addTime.minutes;//check for additional minutes _x000D_
if(addTime.hours) generatedTime+=1000*60*60*addTime.hours;//check for additional hours _x000D_
return new Date(generatedTime);_x000D_
}_x000D_
_x000D_
let futureDate = strtotime(new Date(), {_x000D_
hours: 1, //Adding one hour_x000D_
minutes: 45 //Adding fourty five minutes_x000D_
});_x000D_
document.body.innerHTML = futureDate;
_x000D_
`
If you want to stick to just HTML/CSS on a form, another option is to use a button. Style it and set the disabled
attribute.
I had a doubt that whether the encrypted text will be same for single text when encryption done by multiple times on a same text??
This depends strongly on the crypto algorithm you use:
Equals -
1- Override the GetHashCode method to allow a type to work correctly in a hash table.
2- Do not throw an exception in the implementation of an Equals method. Instead, return false for a null argument.
3-
x.Equals(x) returns true.
x.Equals(y) returns the same value as y.Equals(x).
(x.Equals(y) && y.Equals(z)) returns true if and only if x.Equals(z) returns true.
Successive invocations of x.Equals(y) return the same value as long as the object referenced by x and y are not modified.
x.Equals(null) returns false.
4- For some kinds of objects, it is desirable to have Equals test for value equality instead of referential equality. Such implementations of Equals return true if the two objects have the same value, even if they are not the same instance.
For Example -
Object obj1 = new Object();
Object obj2 = new Object();
Console.WriteLine(obj1.Equals(obj2));
obj1 = obj2;
Console.WriteLine(obj1.Equals(obj2));
Output :-
False
True
while compareTo -
Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.
It returns -
Less than zero - This instance precedes obj in the sort order. Zero - This instance occurs in the same position in the sort order as obj. Greater than zero - This instance follows obj in the sort order.
It can throw ArgumentException if object is not the same type as instance.
For example you can visit here.
So I suggest better to use Equals in place of compareTo.
Use the browser/chrome postman plugin to check the CORS/SOP like a website. Use desktop application instead to avoid these controls.
in your code, at line
map.setCenter(new GLatLng(lat, lon), 5);
the setCenter method takes just one parameter, for the lat:long location. Why are you passing two parameters there ?
I suggest you should change it to,
map.setCenter(new GLatLng(lat, lon));
protected void Application_AcquireRequestState(object sender, EventArgs e)
{
if(Context.Session!= null)
Thread.CurrentThread.CurrentCulture =
Thread.CurrentThread.CurrentUICulture = (Context.Session["culture"] ?? (Context.Session["culture"] = new CultureInfo("pt-BR"))) as CultureInfo;
}
The answer are as below for Window authentication
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=$SQLServer;Database=$SQLDBName;Integrated Security=True;"
If you have a plugin within the browser which knows how to open a PDF file it will open directly. Like in case of images and HTML content.
So the alternative approach is not to send your MIME type in the response. In this way the browser will never know which plugin should open it. Hence it will give you a Save/Open dialog box.
If I understand you right, you can do this:
<img src="image.png" style="background-color:red;" />
In fact, you can even apply a whole background-image
to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

System.out.println("Enter the array values");

My solution: If it is correct*, update the data and viewable items without re-drawing the whole list. Else notifyDataSetChanged.
Correct - oldData size == new data size, and old data IDs and their order == new data IDs and order
How:
/**
* A View can only be used (visible) once. This class creates a map from int (position) to view, where the mapping
* is one-to-one and on.
*
*/
private static class UniqueValueSparseArray extends SparseArray<View> {
private final HashMap<View,Integer> m_valueToKey = new HashMap<View,Integer>();
@Override
public void put(int key, View value) {
final Integer previousKey = m_valueToKey.put(value,key);
if(null != previousKey) {
remove(previousKey);//re-mapping
}
super.put(key, value);
}
}
@Override
public void setData(final List<? extends DBObject> data) {
// TODO Implement 'smarter' logic, for replacing just part of the data?
if (data == m_data) return;
List<? extends DBObject> oldData = m_data;
m_data = null == data ? Collections.EMPTY_LIST : data;
if (!updateExistingViews(oldData, data)) notifyDataSetChanged();
else if (DEBUG) Log.d(TAG, "Updated without notifyDataSetChanged");
}
/**
* See if we can update the data within existing layout, without re-drawing the list.
* @param oldData
* @param newData
* @return
*/
private boolean updateExistingViews(List<? extends DBObject> oldData, List<? extends DBObject> newData) {
/**
* Iterate over new data, compare to old. If IDs out of sync, stop and return false. Else - update visible
* items.
*/
final int oldDataSize = oldData.size();
if (oldDataSize != newData.size()) return false;
DBObject newObj;
int nVisibleViews = m_visibleViews.size();
if(nVisibleViews == 0) return false;
for (int position = 0; nVisibleViews > 0 && position < oldDataSize; position++) {
newObj = newData.get(position);
if (oldData.get(position).getId() != newObj.getId()) return false;
// iterate over visible objects and see if this ID is there.
final View view = m_visibleViews.get(position);
if (null != view) {
// this position has a visible view, let's update it!
bindView(position, view, false);
nVisibleViews--;
}
}
return true;
}
and of course:
@Override
public View getView(final int position, final View convertView, final ViewGroup parent) {
final View result = createViewFromResource(position, convertView, parent);
m_visibleViews.put(position, result);
return result;
}
Ignore the last param to bindView (I use it to determine whether or not I need to recycle bitmaps for ImageDrawable).
As mentioned above, the total number of 'visible' views is roughly the amount that fits on the screen (ignoring orientation changes etc), so no biggie memory-wise.
Search till the seconds for the timestamp column in postgress

you can also use the outside events
When using Netbean, go under project tab and click the dropdown button there to select Libraries folder. Right Click on d Library folder and select 'Add JAR/Folder'.

I have a SOAP WebService extension to log network traffic using a custom [TraceExtension]
. I use this only for Debug builds and omit from Release builds. Use the #if DEBUG
to wrap the [TraceExtension]

$('li[rel=7]').siblings().andSelf();
// or:
$('li[rel=7]').parent().children();
Now that you added that comment explaining that you want to "form an array of rels per column", you should do this:
var rels = [];
$('ul').each(function() {
var localRels = [];
$(this).find('li').each(function(){
localRels.push( $(this).attr('rel') );
});
rels.push(localRels);
});

Make sure that your WebAPI service is expecting a strongly typed object with a structure that matches the JSON that you are passing. And make sure that you stringify the JSON that you are POSTing.
Here is my JavaScript (using AngluarJS):
$scope.updateUserActivity = function (_objuserActivity) {
$http
({
method: 'post',
url: 'your url here',
headers: { 'Content-Type': 'application/json'},
data: JSON.stringify(_objuserActivity)
})
.then(function (response)
{
alert("success");
})
.catch(function (response)
{
alert("failure");
})
.finally(function ()
{
});
And here is my WebAPI Controller:
[HttpPost]
[AcceptVerbs("POST")]
public string POSTMe([FromBody]Models.UserActivity _activity)
{
return "hello";
}
You can do something like this:
// show loading image
$('#loader_img').show();
// main image loaded ?
$('#main_img').on('load', function(){
// hide/remove the loading image
$('#loader_img').hide();
});
You assign load
event to the image which fires when image has finished loading. Before that, you can show your loader image.
It is better to use urlencode
here. Not much difference for single parameter but IMHO makes the code clearer. (It looks confusing to see a function quote_plus
! especially those coming from other languates)
In [21]: query='lskdfj/sdfkjdf/ksdfj skfj'
In [22]: val=34
In [23]: from urllib.parse import urlencode
In [24]: encoded = urlencode(dict(p=query,val=val))
In [25]: print(f"http://example.com?{encoded}")
http://example.com?p=lskdfj%2Fsdfkjdf%2Fksdfj+skfj&val=34
urlencode: https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlencode
quote_plus: https://docs.python.org/3/library/urllib.parse.html#urllib.parse.quote_plus
You have successfully removed the row names. The print.data.frame
method just shows the row numbers if no row names are present.
df1 <- data.frame(values = rnorm(3), group = letters[1:3],
row.names = paste0("RowName", 1:3))
print(df1)
# values group
#RowName1 -1.469809 a
#RowName2 -1.164943 b
#RowName3 0.899430 c
rownames(df1) <- NULL
print(df1)
# values group
#1 -1.469809 a
#2 -1.164943 b
#3 0.899430 c
You can suppress printing the row names and numbers in print.data.frame
with the argument row.names
as FALSE
.
print(df1, row.names = FALSE)
# values group
# -1.4345829 d
# 0.2182768 e
# -0.2855440 f
Edit: As written in the comments, you want to convert this to HTML. From the xtable
and print.xtable
documentation, you can see that the argument include.rownames
will do the trick.
library("xtable")
print(xtable(df1), type="html", include.rownames = FALSE)
#<!-- html table generated in R 3.1.0 by xtable 1.7-3 package -->
#<!-- Thu Jun 26 12:50:17 2014 -->

Yes, it will work fine as you have synchronized
the list . I would suggest you to use CopyOnWriteArrayList
.
CopyOnWriteArrayList<String> cpList=new CopyOnWriteArrayList<String>(new ArrayList<String>());
void remove(String item)
{
do something; (doesn't work on the list)
cpList..remove(item);
}

You can do this setting up an event listener for the 'invalid' across all the inputs of the same type, or just one, depending on what you need, and then setting up the proper message.
[].forEach.call( document.querySelectorAll('[type="email"]'), function(emailElement) {
emailElement.addEventListener('invalid', function() {
var message = this.value + 'is not a valid email address';
emailElement.setCustomValidity(message)
}, false);
emailElement.addEventListener('input', function() {
try{emailElement.setCustomValidity('')}catch(e){}
}, false);
});
The second piece of the script, the validity message will be reset, since otherwise won't be possible to submit the form: for example this prevent the message to be triggered even when the email address has been corrected.
Also you don't have to set up the input field as required, since the 'invalid' will be triggered once you start typing in the input.
Here is a fiddle for that: http://jsfiddle.net/napy84/U4pB7/2/ Hope that helps!
You can create a new row with $
in your data frame corresponding to the Means
DF$Mean <- rowMeans(DF[,2:4])
One liner: $page_path = end(explode('/', trim($_SERVER['REQUEST_URI'], '/')));
Get URI, trim slashes, convert to array, grab last part
You can do that using Linq:
public static string RemoveAllNamespaces(string xmlDocument)
{
var xml = XElement.Parse(xmlDocument);
xml.Descendants().Select(o => o.Name = o.Name.LocalName).ToArray();
return xml.ToString();
}
This would be eliminate the select query from running twice and be better for performance:
Declare @rate int
select
@rate = rate
from
d_payment_index
where
fy = 2007
and payment_year = 2008
and program_id = 18
IF @@rowcount = 0
Set @rate = 0
Select @rate 'rate'
I met the same problem, and I try the pdb.set_trace() before the error line.

I think you are confused about the difference between sourcing and executing a script.
Executing a script means creating a new process, and running the program. The program can be a shell script, or any other type of program. As it is a sub process, any environmental variables changed in the program will not affect the shell.
Sourcing a script can only be used with a bash script (if you are running bash). It effectively types the commands in as if you did them. This is useful as it lets a script change environmental variables in the shell.
Running a script is simple, you just type in the path to the script. .
is the current directory. So ./script.sh
will execute the file script.sh
in the current directory. If the command is a single file (eg script.sh
), it will check all the folders in the PATH variable to find the script. Note that the current directory isn't in PATH, so you can't execute a file script.sh
in the current directory by running script.sh
, you need to run ./script.sh
(unless the current directory is in the PATH, eg you can run ls
while in the /bin
dir).
Sourcing a script doesn't use the PATH, and just searches for the path. Note that source
isn't a program - otherwise it wouldn't be able to change environmental variables in the current shell. It is actually a bash built in command. Search /bin
and /usr/bin
- you won't find a source
program there. So to source a file script.sh
in the current directory, you just use source script.sh
.
How does sudo interact with this? Well sudo takes a program, and executes it as root. Eg sudo ./script.sh
executes script.sh
in a sub process but running as root.
What does sudo source ./script.sh
do however? Remember source
isn't a program (rather a shell builtin)? Sudo expects a program name though, so it searches for a program named source
. It doesn't find one, and so fails. It isn't possible to source a file running as root, without creating a new subprocess, as you cannot change the runner of a program (in this case, bash) after it has started.
I'm not sure what you actually wanted, but hopefully this will clear it up for you.
Here is a concrete example. Make the file script.sh
in your current directory with the contents:
#!/bin/bash
export NEW_VAR="hello"
whoami
echo "Some text"
Make it executable with chmod +x script.sh
.
Now observe what happens with bash:
> ./script.sh
david
Some text
> echo $NEW_VAR
> sudo ./script.sh
root
Some text
> echo $NEW_VAR
> source script.sh
david
Some text
> echo $NEW_VAR
hello
> sudo source script.sh
sudo: source: command not found
I put this forward to help anyone needing something readily practical for giving you a nice, prettified (indented) picture of a JS Node
. None of the other solutions worked for me for a Node
("cyclical error" or whatever...). This walks you through the tree under the DOM Node
(without using recursion) and gives you the depth, tagName
(if applicable) and textContent
(if applicable).
Any other details from the nodes you encounter as you walk the tree under the head node can be added as per your interest...
function printRNode( node ){
// make sort of human-readable picture of the node... a bit like PHP print_r
if( node === undefined || node === null ){
throwError( 'node was ' + typeof node );
}
let s = '';
// NB walkDOM could be made into a utility function which you could
// call with one or more callback functions as parameters...
function walkDOM( headNode ){
const stack = [ headNode ];
const depthCountDowns = [ 1 ];
while (stack.length > 0) {
const node = stack.pop();
const depth = depthCountDowns.length - 1;
// TODO non-text, non-BR nodes could show more details (attributes, properties, etc.)
const stringRep = node.nodeType === 3? 'TEXT: |' + node.nodeValue + '|' : 'tag: ' + node.tagName;
s += ' '.repeat( depth ) + stringRep + '\n';
const lastIndex = depthCountDowns.length - 1;
depthCountDowns[ lastIndex ] = depthCountDowns[ lastIndex ] - 1;
if( node.childNodes.length ){
depthCountDowns.push( node.childNodes.length );
stack.push( ... Array.from( node.childNodes ).reverse() );
}
while( depthCountDowns[ depthCountDowns.length - 1 ] === 0 ){
depthCountDowns.splice( -1 );
}
}
}
walkDOM( node );
return s;
}
Sorry but that's just much too much overhead (above), short and quick, if you have the MapFragment, you also have to map, just do the following:
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
googleMap.setMyLocationEnabled(true)
} else {
// Show rationale and request permission.
}
Code is in Kotlin, hope you don't mind.
have fun
Btw I think this one is a duplicate of: Show Current Location inside Google Map Fragment
Just set in XAML:
<TextBox IsReadOnly="True" Style="{x:Null}" />
So that text will not be grayed-out.
You can pass your arguments using this encodeURIComponent function so you don't have to worry about passing any special characters.
data: "param1=getAccNos¶m2="+encodeURIComponent('Dolce & Gabbana')
OR
var someValue = 'Dolce & Gabbana';
data: "param1=getAccNos¶m2="+encodeURIComponent(someValue)
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent
It's more convenient to use a session, this way you don't have to remember to set headers each time:
session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})
session.get('https://httpbin.org/headers')
By default, session also manages cookies for you. In case you want to disable that, see this question.
You can simply add this CSS to your header
<link href='http://netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css' rel='stylesheet' type='text/css'>
next add this code in place where you want to display a glyph symbol.
<div class="fa fa-search"></div> <!-- smaller -->
<div class="fa fa-search fa-2x"></div> <!-- bigger -->
Have fun.
A variation of the function provided by Paolo Bergantino that works directly on String:
String.prototype.addSlashes = function()
{
//no need to do (str+'') anymore because 'this' can only be a string
return this.replace(/[\\"']/g, '\\$&').replace(/\u0000/g, '\\0');
}
By adding the code above in your library you will be able to do:
var test = "hello single ' double \" and slash \\ yippie";
alert(test.addSlashes());
EDIT:
Following suggestions in the comments, whoever is concerned about conflicts amongst JavaScript libraries can add the following code:
if(!String.prototype.addSlashes)
{
String.prototype.addSlashes = function()...
}
else
alert("Warning: String.addSlashes has already been declared elsewhere.");
If you have a for loop like this:
for(j = 0; j<=90; j++){}
In this loop you are using shorthand provided by java language which means a postfix operator(use-then-change) which is equivalent to j=j+1 , so the changed value is initialized and used for next operation.
for(j = 0; j<=90; j+3){}
In this loop you are just increment your value by 3 but not initializing it back to j variable, so the value of j remains changed.
Unfortunately there's no min
(or max
)-background-size in CSS you can only use
background-size
. However if you are seeking a responsive background image you can use Vmin
and Vmax
units for the background-size
property to achieve something similar.
#one {
background:url('../img/blahblah.jpg') no-repeat;
background-size:10vmin 100%;
}
that will set the height to 10% of the whichever smaller viewport you have whether vertical or horizontal, and will set the width to 100%.

Table Creating
create table emp(eno int identity(100001,1),ename varchar(50))

Output
eno ename
100001 narendra
100002 rama

Using current browsers you can use it like this:
img {
-webkit-filter: grayscale(100%); /* Chrome, Safari, Opera */
filter: grayscale(100%);
}
and to remedy it:
img:hover{
-webkit-filter: grayscale(0%); /* Chrome, Safari, Opera */
filter: grayscale(0%);
}
worked with me and is much shorter. There is even more one can do within the CSS:
filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() |
hue-rotate() | invert() | opacity() | saturate() | sepia() | url();
For more information and supporting browsers see this: http://www.w3schools.com/cssref/css3_pr_filter.asp
I'm going to go against the general wisdom here that std::copy
will have a slight, almost imperceptible performance loss. I just did a test and found that to be untrue: I did notice a performance difference. However, the winner was std::copy
.
I wrote a C++ SHA-2 implementation. In my test, I hash 5 strings using all four SHA-2 versions (224, 256, 384, 512), and I loop 300 times. I measure times using Boost.timer. That 300 loop counter is enough to completely stabilize my results. I ran the test 5 times each, alternating between the memcpy
version and the std::copy
version. My code takes advantage of grabbing data in as large of chunks as possible (many other implementations operate with char
/ char *
, whereas I operate with T
/ T *
(where T
is the largest type in the user's implementation that has correct overflow behavior), so fast memory access on the largest types I can is central to the performance of my algorithm. These are my results:
Time (in seconds) to complete run of SHA-2 tests
std::copy memcpy % increase
6.11 6.29 2.86%
6.09 6.28 3.03%
6.10 6.29 3.02%
6.08 6.27 3.03%
6.08 6.27 3.03%
Total average increase in speed of std::copy over memcpy: 2.99%
My compiler is gcc 4.6.3 on Fedora 16 x86_64. My optimization flags are -Ofast -march=native -funsafe-loop-optimizations
.
Code for my SHA-2 implementations.
I decided to run a test on my MD5 implementation as well. The results were much less stable, so I decided to do 10 runs. However, after my first few attempts, I got results that varied wildly from one run to the next, so I'm guessing there was some sort of OS activity going on. I decided to start over.
Same compiler settings and flags. There is only one version of MD5, and it's faster than SHA-2, so I did 3000 loops on a similar set of 5 test strings.
These are my final 10 results:
Time (in seconds) to complete run of MD5 tests
std::copy memcpy % difference
5.52 5.56 +0.72%
5.56 5.55 -0.18%
5.57 5.53 -0.72%
5.57 5.52 -0.91%
5.56 5.57 +0.18%
5.56 5.57 +0.18%
5.56 5.53 -0.54%
5.53 5.57 +0.72%
5.59 5.57 -0.36%
5.57 5.56 -0.18%
Total average decrease in speed of std::copy over memcpy: 0.11%
Code for my MD5 implementation
These results suggest that there is some optimization that std::copy used in my SHA-2 tests that std::copy
could not use in my MD5 tests. In the SHA-2 tests, both arrays were created in the same function that called std::copy
/ memcpy
. In my MD5 tests, one of the arrays was passed in to the function as a function parameter.
I did a little bit more testing to see what I could do to make std::copy
faster again. The answer turned out to be simple: turn on link time optimization. These are my results with LTO turned on (option -flto in gcc):
Time (in seconds) to complete run of MD5 tests with -flto
std::copy memcpy % difference
5.54 5.57 +0.54%
5.50 5.53 +0.54%
5.54 5.58 +0.72%
5.50 5.57 +1.26%
5.54 5.58 +0.72%
5.54 5.57 +0.54%
5.54 5.56 +0.36%
5.54 5.58 +0.72%
5.51 5.58 +1.25%
5.54 5.57 +0.54%
Total average increase in speed of std::copy over memcpy: 0.72%
In summary, there does not appear to be a performance penalty for using std::copy
. In fact, there appears to be a performance gain.
Explanation of results
So why might std::copy
give a performance boost?
First, I would not expect it to be slower for any implementation, as long as the optimization of inlining is turned on. All compilers inline aggressively; it is possibly the most important optimization because it enables so many other optimizations. std::copy
can (and I suspect all real world implementations do) detect that the arguments are trivially copyable and that memory is laid out sequentially. This means that in the worst case, when memcpy
is legal, std::copy
should perform no worse. The trivial implementation of std::copy
that defers to memcpy
should meet your compiler's criteria of "always inline this when optimizing for speed or size".
However, std::copy
also keeps more of its information. When you call std::copy
, the function keeps the types intact. memcpy
operates on void *
, which discards almost all useful information. For instance, if I pass in an array of std::uint64_t
, the compiler or library implementer may be able to take advantage of 64-bit alignment with std::copy
, but it may be more difficult to do so with memcpy
. Many implementations of algorithms like this work by first working on the unaligned portion at the start of the range, then the aligned portion, then the unaligned portion at the end. If it is all guaranteed to be aligned, then the code becomes simpler and faster, and easier for the branch predictor in your processor to get correct.
Premature optimization?
std::copy
is in an interesting position. I expect it to never be slower than memcpy
and sometimes faster with any modern optimizing compiler. Moreover, anything that you can memcpy
, you can std::copy
. memcpy
does not allow any overlap in the buffers, whereas std::copy
supports overlap in one direction (with std::copy_backward
for the other direction of overlap). memcpy
only works on pointers, std::copy
works on any iterators (std::map
, std::vector
, std::deque
, or my own custom type). In other words, you should just use std::copy
when you need to copy chunks of data around.
J.F. Sebastian's answer is most elegant but requires python 2.6 as fortran pointed out.
For Python version < 2.6, here's the best I can come up with:
from itertools import repeat,ifilter,chain
chain(ifilter(predicate,seq),repeat(None)).next()
Alternatively if you needed a list later (list handles the StopIteration), or you needed more than just the first but still not all, you can do it with islice:
from itertools import islice,ifilter
list(islice(ifilter(predicate,seq),1))
UPDATE: Although I am personally using a predefined function called first() that catches a StopIteration and returns None, Here's a possible improvement over the above example: avoid using filter / ifilter:
from itertools import islice,chain
chain((x for x in seq if predicate(x)),repeat(None)).next()
You're comparing apples to oranges here:
webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service
basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.
So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).
Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:
basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security
wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network
For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding
Clustered Index
A clustered index determine the physical order of DATA in a table.For this reason a table have only 1 clustered index.
"dictionary" No need of any other Index, its already Index according to words
Nonclustered Index
A non clustered index is analogous to an index in a Book.The data is stored in one place. The index is storing in another place and the index have pointers to the storage location of the data.For this reason a table have more than 1 Nonclustered index.
The error you are getting is in line 3. i.e. it is not in
CONSTRAINT no_duplicate_tag UNIQUE (question_id, tag_id)
but earlier:
CREATE TABLE tags
(
(question_id, tag_id) NOT NULL,
Correct table definition is like pilcrow showed.
And if you want to add unique on tag1, tag2, tag3 (which sounds very suspicious), then the syntax is:
CREATE TABLE tags (
question_id INTEGER NOT NULL,
tag_id SERIAL NOT NULL,
tag1 VARCHAR(20),
tag2 VARCHAR(20),
tag3 VARCHAR(20),
PRIMARY KEY(question_id, tag_id),
UNIQUE (tag1, tag2, tag3)
);
or, if you want to have the constraint named according to your wish:
CREATE TABLE tags (
question_id INTEGER NOT NULL,
tag_id SERIAL NOT NULL,
tag1 VARCHAR(20),
tag2 VARCHAR(20),
tag3 VARCHAR(20),
PRIMARY KEY(question_id, tag_id),
CONSTRAINT some_name UNIQUE (tag1, tag2, tag3)
);
json.loads()
takes a JSON encoded string, not a filename. You want to use json.load()
(no s
) instead and pass in an open file object:
with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
data = json.load(jsonfile)
The open()
command produces a file object that json.load()
can then read from, to produce the decoded Python object for you. The with
statement ensures that the file is closed again when done.
The alternative is to read the data yourself and then pass it into json.loads()
.
try
{
}
catch (Exception err)
{
if (err is Web2PDFException)
DoWhatever();
}
but there is probably a better way of doing whatever it is you want.
Import the
UserNotifications
framework and add theUNUserNotificationCenterDelegate
in AppDelegate.swift
Request user permission
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
application.registerForRemoteNotifications()
return true
}
Getting device token
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
print(deviceTokenString)
}
In case of error
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("i am not available in simulator \(error)")
}
In case if you need to know the permissions granted
UNUserNotificationCenter.current().getNotificationSettings(){ (settings) in
switch settings.soundSetting{
case .enabled:
print("enabled sound setting")
case .disabled:
print("setting has been disabled")
case .notSupported:
print("something vital went wrong here")
}
}
The following works:
(
echo "From: ${from}";
echo "To: ${to}";
echo "Subject: ${subject}";
echo "Content-Type: text/html";
echo "MIME-Version: 1.0";
echo "";
echo "${message}";
) | sendmail -t
For troubleshooting msmtp, which is compatible with sendmail
, see:
I believe you probably meant:
from __future__ import print_function
for song in json_object:
# now song is a dictionary
for attribute, value in song.items():
print(attribute, value) # example usage
NB: You could use song.iteritems
instead of song.items
if in Python 2.
In addition to standard net/http package, you can consider using my GoRequest which wraps around net/http and make your life easier without thinking too much about json or struct. But you can also mix and match both of them in one request! (you can see more details about it in gorequest github page)
So, in the end your code will become like follow:
func main() {
url := "http://restapi3.apiary.io/notes"
fmt.Println("URL:>", url)
request := gorequest.New()
titleList := []string{"title1", "title2", "title3"}
for _, title := range titleList {
resp, body, errs := request.Post(url).
Set("X-Custom-Header", "myvalue").
Send(`{"title":"` + title + `"}`).
End()
if errs != nil {
fmt.Println(errs)
os.Exit(1)
}
fmt.Println("response Status:", resp.Status)
fmt.Println("response Headers:", resp.Header)
fmt.Println("response Body:", body)
}
}
This depends on how you want to achieve. I made this library because I have the same problem with you and I want code that is shorter, easy to use with json, and more maintainable in my codebase and production system.
Short and sweet
sp_MSForEachTable 'DECLARE @t AS VARCHAR(MAX);
SELECT @t = CAST(COUNT(1) as VARCHAR(MAX))

Weird! You are saying that you want to generate a recursion of 1<<15 depth???!!!!
I'd suggest DON'T try it. The size of the stack will be 2^15 * sizeof(stack-frame)
. I don't know what stack-frame size is, but 2^15 is 32.768. Pretty much... Well, if it stops at 1024 (2^10) you'll have to make it 2^5 times bigger, it is, 32 times bigger than with your actual setting.
Excerpt from PostgreSQL documentation:
Restricting and cascading deletes are the two most common options. [...]
CASCADE
specifies that when a referenced row is deleted, row(s) referencing it should be automatically deleted as well.
This means that if you delete a category – referenced by books – the referencing book will also be deleted by ON DELETE CASCADE
.
Example:
CREATE SCHEMA shire;
CREATE TABLE shire.clans (
id serial PRIMARY KEY,
clan varchar
);
CREATE TABLE shire.hobbits (
id serial PRIMARY KEY,
hobbit varchar,
clan_id integer REFERENCES shire.clans (id) ON DELETE CASCADE
);
DELETE FROM
clans will CASCADE
to hobbits by REFERENCES
.
sauron@mordor> psql
sauron=# SELECT * FROM shire.clans;
id | clan
----+------------
1 | Baggins
2 | Gamgi
(2 rows)
sauron=# SELECT * FROM shire.hobbits;
id | hobbit | clan_id
----+----------+---------
1 | Bilbo | 1
2 | Frodo | 1
3 | Samwise | 2
(3 rows)
sauron=# DELETE FROM shire.clans WHERE id = 1 RETURNING *;
id | clan
----+---------
1 | Baggins
(1 row)
DELETE 1
sauron=# SELECT * FROM shire.hobbits;
id | hobbit | clan_id
----+----------+---------
3 | Samwise | 2
(1 row)
If you really need the opposite (checked by the database), you will have to write a trigger!
Let me give you a working example to understand the hashable objects in python. I am taking 2 Tuples for this example.Each value in a tuple has a unique Hash Value which never changes during its lifetime. So based on this has value, the comparison between two tuples is done. We can get the hash value of a tuple element using the Id().
This is how you do it in your $(document).ready()
function with FontAwesome Icons:
$( ".owl-prev").html('<i class="fa fa-chevron-left"></i>');
$( ".owl-next").html('<i class="fa fa-chevron-right"></i>');
You can do it as simple as this, I did it in react hooks :
(myNumber == 12) ? "true" : "false"
it was equal to this long if function below :
if (myNumber == 12) {
"true"
} else {
"false"
}
Hope it helps ^_^
Here is a real life sample. Note that String
also implements Comparable
.
class Author implements Comparable<Author>{
String firstName;
String lastName;
@Override
public int compareTo(Author other){
// compareTo should return < 0 if this is supposed to be
// less than other, > 0 if this is supposed to be greater than
// other and 0 if they are supposed to be equal
int last = this.lastName.compareTo(other.lastName);
return last == 0 ? this.firstName.compareTo(other.firstName) : last;
}
}
later..

If you're not beholden to setx
, you can use an alternate command line tool like pathed. There's a more comprehensive list of alternative PATH editors at https://superuser.com/questions/297947/is-there-a-convenient-way-to-edit-path-in-windows-7/655712#655712
You can also edit the registry value directly, which is what setx
does. More in this answer.
It's weird that your %PATH%
is getting truncated at 1024 characters. I thought setx
didn't have that problem. Though you should probably clean up the invalid path entries.
Added path to ~/.zshrc
sudo vi ~/.zshrc
add new path
export PATH="$PATH:[NEW_DIRECTORY]/bin"
Update ~/.zshrc
Save ~/.zshrc
source ~/.zshrc
Check PATH
echo $PATH
There are several ways, although I do believe the one you mention (and dislike) is the most readable one.
>>> t=datetime.date.today()
>>> datetime.datetime.fromordinal(t.toordinal())
datetime.datetime(2009, 12, 20, 0, 0)
>>> datetime.datetime(t.year, t.month, t.day)
datetime.datetime(2009, 12, 20, 0, 0)
>>> datetime.datetime(*t.timetuple()[:-4])
datetime.datetime(2009, 12, 20, 0, 0)
and so forth -- but basically they all hinge on appropriately extracting info from the date
object and ploughing it back into the suitable ctor or classfunction for datetime
.

You can also create a search pipe to filter results:
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name : 'searchPipe',
})
export class SearchPipe implements PipeTransform {
public transform(value, key: string, term: string) {
return value.filter((item) => {
if (item.hasOwnProperty(key)) {
if (term) {
let regExp = new RegExp('\\b' + term, 'gi');
return regExp.test(item[key]);
} else {
return true;
}
} else {
return false;
}
});
}
}
Use pipe in HTML :
<md-input placeholder="Item name..." [(ngModel)]="search" ></md-input>
<div *ngFor="let item of items | searchPipe:'name':search ">
{{item.name}}
</div>

First of all, you aren't forced to use an SMTP on your localhost, if you change that localhost entry into the DNS name of the MTA from your ISP provider (who will let you relay mail) it will work right away, so no messing about with your own email service. Just try to use your providers SMTP servers, it will work right away.
The letters 100000000000 make up a literal integer constant, but the value is too large for the type int
. You need to use a suffix to change the type of the literal, i.e.
long long num3 = 100000000000LL;
The suffix LL
makes the literal into type long long
. C is not "smart" enough to conclude this from the type on the left, the type is a property of the literal itself, not the context in which it is being used.
According to the official documentation on sitemaps.org it needs to be a full URL:
You can specify the location of the Sitemap using a robots.txt file. To do this, simply add the following line including the full URL to the sitemap:
Sitemap: http://www.example.com/sitemap.xml
For those using something like babel stage-2 or transform-class-properties:
import React, { PropTypes, Component } from 'react';
export default class ExampleComponent extends Component {
static contextTypes = {
// some context types
};
static propTypes = {
prop1: PropTypes.object
};
static defaultProps = {
prop1: { foobar: 'foobar' }
};
...
}
Update
As of React v15.5, PropTypes
was moved out of the main React Package (link):
import PropTypes from 'prop-types';
Edit
As pointed out by @johndodo, static
class properties are actually not a part of the ES7 spec, but rather are currently only supported by babel. Updated to reflect that.
You must instruct your logger not to send its messages on up to its parent logger:
...
import java.util.logging.*;
...
Logger logger = Logger.getLogger(this.getClass().getName());
logger.setUseParentHandlers(false);
...
However, this should be done before adding any more handlers to logger.
Use GREATEST()
E.g.:
SELECT GREATEST(2,1);
Note: Whenever if any single value contains null at that time this function always returns null (Thanks to user @sanghavi7)
Alternative to egaga's constructor method of copy. You probably already have a POJO, so just add another method copy()
which returns a copy of the initialized object.
class DummyBean {
private String dummyStr;
private int dummyInt;
public DummyBean(String dummyStr, int dummyInt) {
this.dummyStr = dummyStr;
this.dummyInt = dummyInt;
}
public DummyBean copy() {
return new DummyBean(dummyStr, dummyInt);
}
//... Getters & Setters
}
If you already have a DummyBean
and want a copy:
DummyBean bean1 = new DummyBean("peet", 2);
DummyBean bean2 = bean1.copy(); // <-- Create copy of bean1
System.out.println("bean1: " + bean1.getDummyStr() + " " + bean1.getDummyInt());
System.out.println("bean2: " + bean2.getDummyStr() + " " + bean2.getDummyInt());
//Change bean1
bean1.setDummyStr("koos");
bean1.setDummyInt(88);
System.out.println("bean1: " + bean1.getDummyStr() + " " + bean1.getDummyInt());
System.out.println("bean2: " + bean2.getDummyStr() + " " + bean2.getDummyInt());
Output:
bean1: peet 2 bean2: peet 2 bean1: koos 88 bean2: peet 2
But both works well, it is ultimately up to you...
Defiant.js looks also pretty cool, here's a simple example:
var obj = {
"car": [
{"id": 10, "color": "silver", "name": "Volvo"},
{"id": 11, "color": "red", "name": "Saab"},
{"id": 12, "color": "red", "name": "Peugeot"},
{"id": 13, "color": "yellow", "name": "Porsche"}
],
"bike": [
{"id": 20, "color": "black", "name": "Cannondale"},
{"id": 21, "color": "red", "name": "Shimano"}
]
},
search = JSON.search(obj, '//car[color="yellow"]/name');
console.log( search );
// ["Porsche"]
var reds = JSON.search(obj, '//*[color="red"]');
for (var i=0; i<reds.length; i++) {
console.log( reds[i].name );
}
// Saab
// Peugeot
// Shimano
What I do is create a script in my bin directory that is like an alias. For example I have a script named lsd ls -l | grep ^d
you could make one lsl ls -lR | grep ^l
Just chmod them +x and you are good to go.
Unique pointers are guaranteed to destroy the object they manage when they go out of scope. http://en.cppreference.com/w/cpp/memory/unique_ptr
In this case:
unique_ptr<double> uptr2 (pd);
pd
will be destroyed when uptr2
goes out of scope. This facilitates memory management by automatic deletion.
The case of unique_ptr<int> uptr (new int(3));
is not different, except that the raw pointer is not assigned to any variable here.
Okay, just to clarify things that have already been posted.
You should have the directory com
, containing the directory company
, containing the directory example
, containing the file MyClass.java
.
From the folder containing com
, run:
$ javac com\company\example\MyClass.java
Then:
$ java com.company.example.MyClass Hello from MyClass!
These must both be done from the root of the source tree. Otherwise, javac
and java
won't be able to find any other packages (in fact, java
wouldn't even be able to run MyClass
).
I created the folders "testpackage" and "testpackage2". Inside testpackage, I created TestPackageClass.java containing the following code:
package testpackage;
import testpackage2.MyClass;
public class TestPackageClass {
public static void main(String[] args) {
System.out.println("Hello from testpackage.TestPackageClass!");
System.out.println("Now accessing " + MyClass.NAME);
}
}
Inside testpackage2, I created MyClass.java containing the following code:
package testpackage2;
public class MyClass {
public static String NAME = "testpackage2.MyClass";
}
From the directory containing the two new folders, I ran:
C:\examples>javac testpackage\*.java C:\examples>javac testpackage2\*.java
Then:
C:\examples>java testpackage.TestPackageClass Hello from testpackage.TestPackageClass! Now accessing testpackage2.MyClass
Does that make things any clearer?

In Rails 3, you just need to create a file at views/users/show.json.erb
. The @user
object will be available to the view (just like it would be for html.) You don't even need to_json
anymore.
To summarize, it's just
# users contoller
def show
@user = User.find( params[:id] )
respond_to do |format|
format.html
format.json
end
end
and
/* views/users/show.json.erb */
{
"name" : "<%= @user.name %>"
}
I've found this is often a misnaming error, if you install from a package manager you bin may be called nodejs so you just need to symlink it like so
ln -s /usr/bin/nodejs /usr/bin/node
You can use the *
operator before an iterable to expand it within the function call. For example:
timeseries_list = [timeseries1 timeseries2 ...]
r = scikits.timeseries.lib.reportlib.Report(*timeseries_list)
(notice the *
before timeseries_list
)
From the python documentation:
If the syntax *expression appears in the function call, expression must evaluate to an iterable. Elements from this iterable are treated as if they were additional positional arguments; if there are positional arguments x1, ..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.
This is also covered in the python tutorial, in a section titled Unpacking argument lists, where it also shows how to do a similar thing with dictionaries for keyword arguments with the **
operator.
You were close. format=
needs to be added to the as.Date
call:
mydate <- factor("1/15/2006 0:00:00")
as.Date(mydate, format = "%m/%d/%Y")
## [1] "2006-01-15"
If you're using Angular's ng-repeat to populate the table hackel's jquery snippet will not work by placing it in the document load event. You'll need to run the snippet after angular has finished rendering the table.
To trigger an event after ng-repeat has rendered try this directive:
var app = angular.module('myapp', [])
.directive('onFinishRender', function ($timeout) {
return {
restrict: 'A',
link: function (scope, element, attr) {
if (scope.$last === true) {
$timeout(function () {

I got the directive from here: Use AngularJS just for routing purposes
Just use it as you would a non-concurrent collection. The Concurrent[Collection] classes wrap the regular collections so that you don't have to think about synchronizing access.
Edit: ConcurrentLinkedList isn't actually just a wrapper, but rather a better concurrent implementation. Either way, you don't have to worry about synchronization.
All hail HTML5 _/\_
var videoElement = document.getElementById('videoId');
videoElement.webkitRequestFullScreen();
If you are creating an array then there is no difference, however, the following is neater:
String[] suit = {
"spades",
"hearts",
"diamonds",
"clubs"
};
But, if you want to pass an array into a method you have to call it like this:
myMethod(new String[] {"spades", "hearts"});
myMethod({"spades", "hearts"}); //won't compile!
I guess it follows mathematical tradition. In mathematics, it is often said "let x be arbitrary real number" or like that.
When I try:
<input type="button" id="moreFields" onclick="alert('The text will be show!!'); return false;" value="Give me more fields!" />
It's worked well. So I think the problem is position of moreFields() function. Ensure that function will be define before your input tag.
Pls try:
<script type="text/javascript">
function moreFields() {
alert("The text will be show");
}
</script>
<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!" />
Hope it helped.
UPDATE mytable SET column=LEFT(column, LEN(column)-5)
Removes the last 5 characters from the column (every row in mytable)
>>> '\\&' == '\&'
True
>>> len('\\&')
2
>>> print('\\&')
\&
Or in other words: '\\&'
only contains one backslash. It's just escaped in the python shell's output for clarity.
If you don't want to deal with interactive mode then do this:
Update your last pushed commit
git commit --amend -m "New commit message."
Push your new commit message (this will replace the old last commit message to this new one)
git push origin --force **branch-name**

I ran into this issue when I was referencing
[drive]:\Program Files\Java\jdk1.8.0_65
in my JAVA_HOME environment var instead of the Android Studio recommended
[drive]:\Program Files\Java\jdk1.7.0_79.
I am using the x64 version of the JDK on Windows 10 Pro.
From the Android Studio installation instructions.
Before you set up Android Studio, be sure you have installed JDK 6 or higher (the JRE alone is not sufficient)—JDK 7 is required when developing for Android 5.0 and higher. To check if you have JDK installed (and which version), open a terminal and type javac -version. If the JDK is not available or the version is lower than version 6, download the Java SE Development Kit 7
http://developer.android.com/sdk/installing/index.html?pkg=studio
I followed the instructions above by Gene in Android Studio 1.5.1 but it added this to my build.gradle file:
compile 'platforms:android:android-support-v4:23.1.1'
so I changed it to:
compile 'com.android.support:support-v4:23.1.1'
And it started working.
https://docs.python.org/3/library/functions.html#max
If multiple items are maximal, the function returns the first one encountered. This is consistent with other sort-stability preserving tools such as sorted(iterable, key=keyfunc, reverse=True)[0]
To get more than just the first use the sort method.
import operator
x = [2, 5, 7, 4, 8, 2, 6, 1, 7, 1, 8, 3, 4, 9, 3, 6, 5, 0, 9, 0]
min = False
max = True
min_val_index = sorted( list(zip(x, range(len(x)))), key = operator.itemgetter(0), reverse = min )
max_val_index = sorted( list(zip(x, range(len(x)))), key = operator.itemgetter(0), reverse = max )
min_val_index[0]
>(0, 17)
max_val_index[0]
>(9, 13)
import ittertools
max_val = max_val_index[0][0]
maxes = [n for n in itertools.takewhile(lambda x: x[0] == max_val, max_val_index)]

(np.where(np.isnan(A)))[0].shape[0]
will be greater than 0
if A
contains at least one element of nan
, A
could be an n x m

Example:
import numpy as np
A = np.array([1,2,4,np.nan])
if (np.where(np.isnan(A)))[0].shape[0]:
print "A contains nan"
else:
print "A does not contain nan"

Just go to web.config file and add following
<system.webServer>
<defaultDocument>
<files>
<clear />
<add value="Path of your Page" />
</files>
</defaultDocument>
</system.webServer>
You need to set permission for the user controls .
In my case was that I have enable "Show All Files". Visual Studio 2017
Make use of JSONDecoder().decode
See this video JSON parsing with Swift 4
struct Post: Codable {
let userId: Int
let id: Int
let title: String
let body: String
}
URLSession.shared.dataTask(with: URL(string: "https://jsonplaceholder.typicode.com/posts")!) { (data, response, error) in
guard let response = response as? HTTPURLResponse else {
print("HTTPURLResponse error")
return
}
guard 200 ... 299 ~= response.statusCode else {
print("Status Code error \(response.statusCode)")
return
}
guard let data = data else {
print("No Data")
return
}
let posts = try! JSONDecoder().decode([Post].self, from: data)
print(posts)
}.resume()
A working example in case of using angular-cli:
npm i bootstrap-schematics
ng generate bootstrap-shell -c bootstrap-schematics -v 4
npm install
Works for css and scss. Bootstrap v3 and v4 are available.
More information about bootstrap-schematics please find here.
Are you sure that you want "055" as opposed to "55"? Some programs interpret a leading zero as meaning octal, so that it would read 055 as (decimal) 45 instead of (decimal) 55.
That should just mean dropping the '0' (zero-fill) flag.
e.g., change System.out.printf("%03d ", x);
to the simpler System.out.printf("%3d ", x);
For Oracle versions which does not support the WM_CONCAT, the following can be used
select "User", RTRIM(
XMLAGG (XMLELEMENT(e, department||',') ORDER BY department).EXTRACT('//text()') , ','
) AS departments
from yourtable
group by "User"
This one is much more powerful and flexible - you can specify both delimiters and sort order within each group as in listagg.
I'm using following markup and had encoutered the same problem:
<ul class="nav">
<li><a href="abc.html">abc</a></li>
<li><a href="def.html">def</a></li>
</ul>
Here I have used the following logic:
$(".nav > li").click(function(e){
if(e.target != this) return; // only continue if the target itself has been clicked
// this section only processes if the .nav > li itself is clicked.
alert("you clicked .nav > li, but not it's children");
});
In terms of the exact question, I can see that working as follows:
$(".example").click(function(e){
if(e.target != this) return; // only continue if the target itself has been clicked
$(".example").fadeOut("fast");
});
or of course the other way around:
$(".example").click(function(e){
if(e.target == this){ // only if the target itself has been clicked
$(".example").fadeOut("fast");
}
});
Hope that helps.
You need an scp client. Putty is not one. You can use WinSCP or PSCP. Both are free software.
You can see the button "Code" in the attached screenshot, press it and you can get your code in many different languages including PHP cURL
strtotime()
is returning bool(false)
, because it can't parse the string '+one year'
(it doesn't understand "one"). false
is then being implicitly cast to the integer
timestamp 0
. It's a good idea to verify strtotime()
's output isn't bool(false)
before you go shoving it in other functions.
Return Values
Returns a timestamp on success, FALSE otherwise. Previous to PHP 5.1.0, this function would return -1 on failure.
You can overlay a big, semi-transparent <div>
that takes all the clicks. Just append a new <div>
to <body>
with this style:
.overlay {
background-color: rgba(1, 1, 1, 0.7);
bottom: 0;
left: 0;
position: fixed;
right: 0;
top: 0;
}
There can be an even simpler representation assuming that one has to only test graph algorithms not use them(graph) else where. This can be as a map from vertices to their adjacency lists as shown below :-
#include<bits/stdc++.h>
using namespace std;
/* implement the graph as a map from the integer index as a key to the adjacency list
* of the graph implemented as a vector being the value of each individual key. The
* program will be given a matrix of numbers, the first element of each row will
* represent the head of the adjacency list and the rest of the elements will be the
* list of that element in the graph.
*/
typedef map<int, vector<int> > graphType;
int main(){
graphType graph;
int vertices = 0;
cout << "Please enter the number of vertices in the graph :- " << endl;
cin >> vertices;
if(vertices <= 0){
cout << "The number of vertices in the graph can't be less than or equal to 0." << endl;
exit(0);
}
cout << "Please enter the elements of the graph, as an adjacency list, one row after another. " << endl;
for(int i = 0; i <= vertices; i++){
vector<int> adjList; //the vector corresponding to the adjacency list of each vertex
int key = -1, listValue = -1;
string listString;
getline(cin, listString);
if(i != 0){
istringstream iss(listString);
iss >> key;
iss >> listValue;
if(listValue != -1){
adjList.push_back(listValue);
for(; iss >> listValue; ){
adjList.push_back(listValue);
}
graph.insert(graphType::value_type(key, adjList));
}
else
graph.insert(graphType::value_type(key, adjList));
}
}
//print the elements of the graph
cout << "The graph that you entered :- " << endl;
for(graphType::const_iterator iterator = graph.begin(); iterator != graph.end(); ++iterator){
cout << "Key : " << iterator->first << ", values : ";
vector<int>::const_iterator vectBegIter = iterator->second.begin();
vector<int>::const_iterator vectEndIter = iterator->second.end();
for(; vectBegIter != vectEndIter; ++vectBegIter){
cout << *(vectBegIter) << ", ";
}
cout << endl;
}
}
Twitter has a public API which returns JSON, for example -
A GET
request to:
https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=mralexgray&count=1
,
EDIT: Removed due to twitter restricting their API with OAUTH
requirements...
{"errors": [{"message": "The Twitter REST API v1 is no longer active. Please migrate to API v1.1. https://dev.twitter.com/docs/api/1.1/overview.", "code": 68}]}
Replacing it with a simple example of the Github API - that returns a tree, of in this case, my repositories...
I won't include the output, as it's long.. (returns 30 repos at a time) ... But here is proof of it's tree-ed-ness.
