As jackrabb1t pointed out, --follow
is more robust since it continues listing the history beyond renames/moves. So, if you are looking for a file that is not currently in the same path or a file that has been renamed throughout various commits, --follow will track it.
This can be a better option if you want to visualize the name/path changes:
git log --follow --name-status -- <path>
But if you want a more compact list with only what matters:
git log --follow --name-status --format='%H' -- <path>
or even
git log --follow --name-only --format='%H' -- <path>
The downside is that --follow
only works for a single file.
Is there a native android way to get a reference to the currently running Activity from a service?
You may not own the "currently running Activity".
I have a service running on the background, and I would like to update my current Activity when an event occurs (in the service). Is there a easy way to do that (like the one I suggested above)?
Intent
to the activity -- here is a sample project demonstrating this patternPendingIntent
(e.g., via createPendingResult()
) that the service invokesbindService()
, and have the service call an event method on that callback/listener objectIntent
to the activity, with a low-priority BroadcastReceiver
as backup (to raise a Notification
if the activity is not on-screen) -- here is a blog post with more on this patternAdd this to onCreate
// Getting application context
Context context = getActivity();
The default name for a configuration file is [yourexe].exe.config. So notepad.exe will have a configuration file named notepad.exe.config, in the same folder as the program. This is a general configuration file for all aspects of the CLR and Framework, but it can contain your own settings under an <appSettings>
node.
The <appSettings>
element creates a collection of name-value pairs which can be accessed as System.Configuration.ConfigurationSettings.AppSettings
. There is no way to save changes back to the configuration file, however.
It is also possible to add your own custom elements to a configuration file - for example, to define a structured setting - by creating a class that implements IConfigurationSectionHandler
and adding it to the <configSections>
element of the configuration file. You can then access it by calling ConfigurationSettings.GetConfig
.
.NET 2.0 adds a new class, System.Configuration.ConfigurationManager
, which supports multiple files, with per-user overrides of per-system data. It also supports saving modified configurations back to settings files.
Visual Studio creates a file called App.config
, which it copies to the EXE folder, with the correct name, when the project is built.
The JQuery answer. Since JavaScript was invented in order to develop JQuery, I am giving you an example in JQuery doing this:
<div class="menu">
<a href="http://example.org">Example</a>
<a href="http://foobar.com">Foobar.com</a>
</div>
<script>
jQuery( 'div.menu a' )
.click(function() {
do_the_click( this.href );
return false;
});
// play the funky music white boy
function do_the_click( url )
{
alert( url );
}
</script>
According to the jQuery documentation for .keypress(), it does not catch non-printable characters, so backspace will not work on keypress, but it is caught in keydown and keyup:
The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events. Other differences between the two events may arise depending on platform and browser. (https://api.jquery.com/keypress/)
In some instances keyup isn't desired or has other undesirable effects and keydown is sufficient, so one way to handle this is to use keydown
to catch all keystrokes then set a timeout of a short interval so that the key is entered, then do processing in there after.
jQuery(el).keydown( function() {
var that = this; setTimeout( function(){
/** Code that processes backspace, etc. **/
}, 100 );
} );
I answered a very similar question:
https://stackoverflow.com/a/15982217/1467082
You simply need to iterate over the series' .Points
collection, and then you can assign the points' .Format.Fill.ForeColor.RGB
value based on whatever criteria you need.
UPDATED
The code below will color the chart per the screenshot. This only assumes three colors are used. You can add additional case statements for other color values, and update the assignment of myColor
to the appropriate RGB values for each.
Option Explicit
Sub ColorScatterPoints()
Dim cht As Chart
Dim srs As Series
Dim pt As Point
Dim p As Long
Dim Vals$, lTrim#, rTrim#
Dim valRange As Range, cl As Range
Dim myColor As Long
Set cht = ActiveSheet.ChartObjects(1).Chart
Set srs = cht.SeriesCollection(1)
'## Get the series Y-Values range address:
lTrim = InStrRev(srs.Formula, ",", InStrRev(srs.Formula, ",") - 1, vbBinaryCompare) + 1
rTrim = InStrRev(srs.Formula, ",")
Vals = Mid(srs.Formula, lTrim, rTrim - lTrim)
Set valRange = Range(Vals)
For p = 1 To srs.Points.Count
Set pt = srs.Points(p)
Set cl = valRange(p).Offset(0, 1) '## assume color is in the next column.
With pt.Format.Fill
.Visible = msoTrue
'.Solid 'I commented this out, but you can un-comment and it should still work
'## Assign Long color value based on the cell value
'## Add additional cases as needed.
Select Case LCase(cl)
Case "red"
myColor = RGB(255, 0, 0)
Case "orange"
myColor = RGB(255, 192, 0)
Case "green"
myColor = RGB(0, 255, 0)
End Select
.ForeColor.RGB = myColor
End With
Next
End Sub
Simple, Elegant, and Powerful:
A generator expression in conjuction with a builtin… (python 2.5+)
any(x for x in mylist if x.n == 10)
Uses the Python any()
builtin, which is defined as follows:
any(iterable)
->
Return True if any element of the iterable is true. Equivalent to:
def any(iterable):
for element in iterable:
if element:
return True
return False
You should use a callback parameter:
function Typer(callback)
{
var srcText = 'EXAMPLE ';
var i = 0;
var result = srcText[i];
var interval = setInterval(function() {
if(i == srcText.length - 1) {
clearInterval(interval);
callback();
return;
}
i++;
result += srcText[i].replace("\n", "<br />");
$("#message").html(result);
},
100);
return true;
}
function playBGM () {
alert("Play BGM function");
$('#bgm').get(0).play();
}
Typer(function () {
playBGM();
});
// or one-liner: Typer(playBGM);
So, you pass a function as parameter (callback
) that will be called in that if
before return
.
Also, this is a good article about callbacks.

The syntax of ng-style
is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:
<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>
And then in your controller:
$scope.width = '900px';
$scope.bgColor = 'red';
This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.
The problem has been well-identified. But there's a solution; make doSomething generic:
<T extends Animal> void doSomething<List<T> animals) {
}
now you can call doSomething with either List<Dog> or List<Cat> or List<Animal>.
Try this:
<div style="background:transparent !important" class="jumbotron">
<h1>Welcome!</h1>
<p>We're an awesome company that creates virtual things for portable devices.</p>
<p><a class="btn btn-primary btn-lg" role="button">Learn more</a></p>
</div>
Inline CSS gets preference over classes defined in a .css
file and the classes declared inside <style>
Use this:
os.path.splitext("name.fasta")[0]+".aln"
And here is how the above works:
The splitext method separates the name from the extension creating a tuple:
os.path.splitext("name.fasta")
the created tuple now contains the strings "name" and "fasta". Then you need to access only the string "name" which is the first element of the tuple:
os.path.splitext("name.fasta")[0]
And then you want to add a new extension to that name:
os.path.splitext("name.fasta")[0]+".aln"
You can do something like this to find out the cookies's value:
Request.Cookies[SESSION_COOKIE_NAME].Value

var spi = new ServiceProcessInstaller();
var si = new ServiceInstaller();
spi.Account = ServiceAccount.LocalSystem;
spi.Username = null;
spi.Password = null;

si.ServiceName = Program.ServiceName;
si.StartType = ServiceStartMode.Automatic;
Installers.Add(spi);

}
}
}
Actually the list of parameters could be accessed with $1 $2 ...
etc.
Which is exactly equivalent to:
${!i}
So, the list of parameters could be changed with set,
and ${!i}
is the correct way to access them:
$ set -- aa bb cc dd 55 ff gg hh ii jjj kkk lll
$ for ((i=0;i<=$#;i++)); do echo "$#" "$i" "${!i}"; done
12 1 aa
12 2 bb
12 3 cc
12 4 dd
12 5 55
12 6 ff
12 7 gg
12 8 hh
12 9 ii
12 10 jjj
12 11 kkk
12 12 lll
For your specific case, this could be used (without the need for arrays), to set the list of arguments when none was given:
if [ "$#" -eq 0 ]; then
set -- defaultarg1 defaultarg2
fi
which translates to this even simpler expression:
[ "$#" == "0" ] && set -- defaultarg1 defaultarg2
Btw, you cannot encrypt with DSA, only sign. Although they are mathematically equivalent (more or less) you cannot use DSA in practice as an encryption scheme, only as a digital signature scheme.
The same problem happened with me also, nothing worked... I first deleted the service (in my case MySQL80 and MySQL) by command:
sc delete MySQL80
sc delete MySql
and then reinstalled MySQL. Mine was MySQL 8.0. And then everything was back to normal.
${project.basedir}
is the root directory of your project.
${project.build.directory}
is equivalent to ${project.basedir}/target
as it is defined here: https://github.com/apache/maven/blob/trunk/maven-model-builder/src/main/resources/org/apache/maven/model/pom-4.0.0.xml#L53
"\n\r" produces 2 new lines while "\n","\r" & "\r\n" produce single lines if, in the Header, you use content-type: text/plain
.
Beware: If you do the Following php code:
$message='ab<br>cd<br>e<br>f';
print $message.'<br><br>';
$message=str_replace('<br>',"\r\n",$message);
print $message;
you get the following in the Windows browser:
ab
cd
e
f
ab cd e f
and with content-type: text/plain
you get the following in an email output;
ab
cd
e
f
Edit: as @aix suggested, a better (more fair) way to compare the speed difference:
In [1]: %timeit abs(5)
10000000 loops, best of 3: 86.5 ns per loop
In [2]: from math import fabs
In [3]: %timeit fabs(5)
10000000 loops, best of 3: 115 ns per loop
In [4]: %timeit abs(-5)
10000000 loops, best of 3: 88.3 ns per loop
In [5]: %timeit fabs(-5)
10000000 loops, best of 3: 114 ns per loop
In [6]: %timeit abs(5.0)
10000000 loops, best of 3: 92.5 ns per loop
In [7]: %timeit fabs(5.0)
10000000 loops, best of 3: 93.2 ns per loop
In [8]: %timeit abs(-5.0)
10000000 loops, best of 3: 91.8 ns per loop
In [9]: %timeit fabs(-5.0)
10000000 loops, best of 3: 91 ns per loop
So it seems abs()
only has slight speed advantage over fabs()
for integers. For floats, abs()
and fabs()
demonstrate similar speed.
In addition to what @aix has said, one more thing to consider is the speed difference:
In [1]: %timeit abs(-5)
10000000 loops, best of 3: 102 ns per loop
In [2]: import math
In [3]: %timeit math.fabs(-5)
10000000 loops, best of 3: 194 ns per loop
So abs()
is faster than math.fabs()
.
I know this answer is coming years after the fact and there is already a great JSP answer by Will Hartung, but there is Facelets, they are even mentioned in the answers from the linked question in the original question.
Facelets SO tag description
Facelets is an XML-based view technology for the JavaServer Faces framework. Designed specifically for JSF, Facelets is intended to be a simpler and more powerful alternative to JSP-based views. Initially a separate project, the technology was standardized as part of JSF 2.0 and Java-EE 6 and has deprecated JSP. Almost all JSF 2.0 targeted component libraries do not support JSP anymore, but only Facelets.
Sadly the best plain tutorial description I found was on Wikipedia and not a tutorial site. In fact the section describing templates even does along the lines of what the original question was asking for.
Due to the fact that Java-EE 6 has deprecated JSP I would recommend going with Facelets despite the fact that it looks like there might be more required for little to no gain over JSP.
My stringdata
is coming from PHP file but still, I indicate here in var
. When i directly take my json into obj
it will nothing show thats why i put my json file as
var obj=JSON.parse(stringdata);
so after that i get message
obj and show in alert box then I get data
which is json array and store in one varible ArrObj
then i read first object of that array with key value like this ArrObj[0].id
var stringdata={
"success": true,
"message": "working",
"data": [{
"id": 1,
"name": "foo"
}]
};
var obj=JSON.parse(stringdata);
var key = "message";
alert(obj[key]);
var keyobj = "data";
var ArrObj =obj[keyobj];
alert(ArrObj[0].id);
In more explanation for n. 'pronouns' m.
's answer,
Public-key crypto is not for encrypting arbitrarily long files. One uses a symmetric cipher (say AES) to do the normal encryption. Each time a new random symmetric key is generated, used, and then encrypted with the RSA cipher (public key). The ciphertext together with the encrypted symmetric key is transferred to the recipient. The recipient decrypts the symmetric key using his private key, and then uses the symmetric key to decrypt the message.
There is the flow of Encryption:
+---------------------+ +--------------------+
| | | |
| generate random key | | the large file |
| (R) | | (F) |
| | | |
+--------+--------+---+ +----------+---------+
| | |
| +------------------+ |
| | |
v v v
+--------+------------+ +--------+--+------------+
| | | |
| encrypt (R) with | | encrypt (F) |
| your RSA public key | | with symmetric key (R) |
| | | |
| ASym(PublicKey, R) | | EF = Sym(F, R) |
| | | |
+----------+----------+ +------------+-----------+
| |
+------------+ +--------------+
| |
v v
+--------------+-+---------------+
| |
| send this files to the peer |
| |
| ASym(PublicKey, R) + EF |
| |
+--------------------------------+
And the flow of Decryption:
+----------------+ +--------------------+
| | | |
| EF = Sym(F, R) | | ASym(PublicKey, R) |
| | | |
+-----+----------+ +---------+----------+
| |
| |
| v
| +-------------------------+-----------------+
| | |
| | restore key (R) |
| | |
| | R <= ASym(PrivateKey, ASym(PublicKey, R)) |
| | |
| +---------------------+---------------------+
| |
v v
+---+-------------------------+---+
| |
| restore the file (F) |
| |
| F <= Sym(Sym(F, R), R) |
| |
+---------------------------------+
Besides, you can use this commands:
# generate random symmetric key
openssl rand -base64 32 > /config/key.bin
# encryption
openssl rsautl -encrypt -pubin -inkey /config/public_key.pem -in /config/key.bin -out /config/key.bin.enc
openssl aes-256-cbc -a -pbkdf2 -salt -in $file_name -out $file_name.enc -k $(cat /config/key.bin)
# now you can send this files: $file_name.enc + /config/key.bin.enc
# decryption
openssl rsautl -decrypt -inkey /config/private_key.pem -in /config/key.bin.enc -out /config/key.bin
openssl aes-256-cbc -d -a -in $file_name.enc -out $file_name -k $(cat /config/key.bin)
I had trouble getting this to work and added another solution for anyone wanting/ needing to use FromCollection.
Instead of:
@Html.CheckBoxFor(model => true, item.TemplateId)
Format html helper like so:
@Html.CheckBoxFor(model => model.SomeProperty, new { @class = "form-control", Name = "SomeProperty"})
Then in the viewmodel/model wherever your logic is:
public void Save(FormCollection frm)
{
// to do instantiate object.
instantiatedItem.SomeProperty = (frm["SomeProperty"] ?? "").Equals("true", StringComparison.CurrentCultureIgnoreCase);
// to do and save changes in database.
}
In order for TypeScript Compiler to use all visible Type Definitions during compilation, types
option should be removed completely from compilerOptions
field in tsconfig.json
file.
This problem arises when there exists some types
entries in compilerOptions
field, where at the same time jest
entry is missing.
So in order to fix the problem, compilerOptions
field in your tscongfig.json
should either include jest
in types
area or get rid of types
comnpletely:
{
"compilerOptions": {
"esModuleInterop": true,
"target": "es6",
"module": "commonjs",
"outDir": "dist",
"types": ["reflect-metadata", "jest"], //<-- add jest or remove completely
"moduleResolution": "node",
"sourceMap": true
},
"include": [
"src/**/*.ts"
],
"exclude": [
"node_modules"
]
}
GLib is a portability/utility library for C which forms the basis of the GTK+ graphical toolkit. It can be used as a standalone library.
It contains portable wrappers for managing directories. See Glib File Utilities documentation for details.
Personally, I wouldn't even consider writing large amounts of C-code without something like GLib behind me. Portability is one thing, but it's also nice to get data structures, thread helpers, events, mainloops etc. for free
Jikes, I'm almost starting to sound like a sales guy :) (don't worry, glib is open source (LGPL) and I'm not affiliated with it in any way)
Maximum number of elements of an array
is (2^31)-1
or 2 147 483 647
Here an answer for those who'd like to have preinitialized lists of lists. Needs Java 8+.
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.IntStream;
class Scratch {
public static void main(String[] args) {
int M = 4;
int N = 3;
// preinitialized array (== list of lists) of strings, sizes not fixed
List<List<String>> listOfListsOfString = initializeListOfListsOfT(M, N, "-");
System.out.println(listOfListsOfString);
// preinitialized array (== list of lists) of int (primitive type), sizes not fixed
List<List<Integer>> listOfListsOfInt = initializeListOfListsOfInt(M, N, 7);
System.out.println(listOfListsOfInt);
}
public static <T> List<List<T>> initializeListOfListsOfT(int m, int n, T initValue) {
return IntStream
.range(0, m)
.boxed()
.map(i -> new ArrayList<T>(IntStream
.range(0, n)
.boxed()
.map(j -> initValue)
.collect(Collectors.toList()))
)
.collect(Collectors.toList());
}
public static List<List<Integer>> initializeListOfListsOfInt(int m, int n, int initValue) {
return IntStream
.range(0, m)
.boxed()
.map(i -> new ArrayList<>(IntStream
.range(0, n)
.map(j -> initValue)
.boxed()
.collect(Collectors.toList()))
)
.collect(Collectors.toList());
}
}
Output:
[[-, -, -], [-, -, -], [-, -, -], [-, -, -]]
[[7, 7, 7], [7, 7, 7], [7, 7, 7], [7, 7, 7]]
Side note for those wondering about IntStream
:
IntStream
.range(0, m)
.boxed()
is equivalent to
Stream
.iterate(0, j -> j + 1)
.limit(n)
In SSMS, "Query" menu item... "Results to"... "Results to File"
Shortcut = CTRL+shift+F
You can set it globally too
"Tools"... "Options"... "Query Results"... "SQL Server".. "Default destination" drop down
Edit: after comment
In SSMS, "Query" menu item... "SQLCMD" mode
This allows you to run "command line" like actions.
A quick test in my SSMS 2008
:OUT c:\foo.txt
SELECT * FROM sys.objects
Edit, Sep 2012
:OUT c:\foo.txt
SET NOCOUNT ON;SELECT * FROM sys.objects
It turns out that, out of the four possible permutations of including or excluding trailing or leading forward slashes on the BaseAddress
and the relative URI passed to the GetAsync
method -- or whichever other method of HttpClient
-- only one permutation works. You must place a slash at the end of the BaseAddress
, and you must not place a slash at the beginning of your relative URI, as in the following example.
using (var handler = new HttpClientHandler())
using (var client = new HttpClient(handler))
{
client.BaseAddress = new Uri("http://something.com/api/");
var response = await client.GetAsync("resource/7");
}
Even though I answered my own question, I figured I'd contribute the solution here since, again, this unfriendly behavior is undocumented. My colleague and I spent most of the day trying to fix a problem that was ultimately caused by this oddity of HttpClient
.
Append .done()
to your ajax request.
$.ajax({
url: "test.html",
context: document.body
}).done(function() { //use this
alert("DONE!");
});
See the JQuery Doc for .done()
If your MyFunction()
method is defined only in one class (and its descendants), try
void MyMethod(Object obj)
{
var o = obj as MyClass;
if (o != null)
o.MyFunction();
}
If you have a large number in unrelated classes defining the function you want to call, you should define an interface and make your classes define that interface:
interface IMyInterface
{
void MyFunction();
}
void MyMethod(Object obj)
{
var o = obj as IMyInterface;
if (o != null)
o.MyFunction();
}
Another use that I've been putting to good purpose is fetching data from multiple sources. In the example below, I'm fetching multiple, independent JSON schema objects used in an existing application for validation between a client and a REST server. In this case, I don't want the browser-side application to start loading data before it has all the schemas loaded. $.when.apply().then() is perfect for this. Thank to Raynos for pointers on using then(fn1, fn2) to monitor for error conditions.
fetch_sources = function (schema_urls) {
var fetch_one = function (url) {
return $.ajax({
url: url,
data: {},
contentType: "application/json; charset=utf-8",
dataType: "json",
});
}
return $.map(schema_urls, fetch_one);
}
var promises = fetch_sources(data['schemas']);
$.when.apply(null, promises).then(
function () {
var schemas = $.map(arguments, function (a) {
return a[0]
});
start_application(schemas);
}, function () {
console.log("FAIL", this, arguments);
});
create a view on the custom cell in the table view and apply PanGestureRecognizer to the view on the cell.Add the buttons to the custom cell, when you swipe the view on the custom cell then the buttons on the custom cell will be visible.
UIGestureRecognizer* recognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
recognizer.delegate = self;
[YourView addGestureRecognizer:recognizer];
And handle the panning on the view in the method
if (recognizer.state == UIGestureRecognizerStateBegan) {
// if the gesture has just started, record the current centre location
_originalCenter = vwCell.center;
}
// 2
if (recognizer.state == UIGestureRecognizerStateChanged) {

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc
A set of simple examples:
Using Gson:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
public class Gson {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
com.google.gson.Gson gson = new com.google.gson.Gson();
Response respuesta = gson.fromJson(json, Response.class);
System.out.println(respuesta.getExample());
System.out.println(respuesta.getFr());
} catch (IOException ex) {
}
return null;
}
public class Response{
private String example;
private String fr;
public String getExample() {
return example;
}
public void setExample(String example) {
this.example = example;
}
public String getFr() {
return fr;
}
public void setFr(String fr) {
this.fr = fr;
}
}
}
Using json-simple:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
public class JsonSimple {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
try {
JSONParser parser = new JSONParser();
Object resultObject = parser.parse(json);
if (resultObject instanceof JSONArray) {
JSONArray array=(JSONArray)resultObject;
for (Object object : array) {
JSONObject obj =(JSONObject)object;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
}else if (resultObject instanceof JSONObject) {
JSONObject obj =(JSONObject)resultObject;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
} catch (Exception e) {
// TODO: handle exception
}
} catch (IOException ex) {
}
return null;
}
}
etc...
If anyone is using Maven, you'll need to add the dependency in the POM.XML file. The latest version as of this post is below:
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.1-api</artifactId>
<version>1.0.0.Final</version>
</dependency>
Still anyone have this problem, use following code inside your form as below.
echo '<input type = "hidden" name = "_token" value = "'. csrf_token().'" >';
Here's the most basic way:
$url = "http://other-site/image.png";
$dir = "/my/local/dir/";
$rfile = fopen($url, "r");
$lfile = fopen($dir . basename($url), "w");
while(!feof($url)) fwrite($lfile, fread($rfile, 1), 1);
fclose($rfile);
fclose($lfile);
But if you're doing lots and lots of this (or your host blocks file access to remote systems), consider using CURL, which is more efficient, mildly faster and available on more shared hosts.
You can also spoof the user agent to look like a desktop rather than a bot!
$url = "http://other-site/image.png";
$dir = "/my/local/dir/";
$lfile = fopen($dir . basename($url), "w");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)');
curl_setopt($ch, CURLOPT_FILE, $lfile);
fclose($lfile);
curl_close($ch);
With both instances, you might want to pass it through GD to make sure it really is an image.
check your privilege
in my case i need to check my username
i have two or three repository with seperate credentials.
problem is my permission i have two private git server and repositories
this second account is admin of that new repo and first one is my default user account and i should grant permission to first
You might want to look at csounds, also. It has several API's, including Python. It might be able to interact with an A-D interface and gather sound samples.
I spent a lot of time researching this and learning how it all works, after really messing up the event triggers. Since there was so much scattered info I decided to share what I have found to work all in one place, step by step as follows:
1) Open VBA Editor, under VBA Project (YourWorkBookName.xlsm) open Microsoft Excel Object and select the Sheet to which the change event will pertain.
2) The default code view is "General." From the drop-down list at the top middle, select "Worksheet."
3) Private Sub Worksheet_SelectionChange is already there as it should be, leave it alone. Copy/Paste Mike Rosenblum's code from above and change the .Range reference to the cell for which you are watching for a change (B3, in my case). Do not place your Macro yet, however (I removed the word "Macro" after "Then"):
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("H5")) Is Nothing Then
End Sub
or from the drop-down list at the top left, select "Change" and in the space between Private Sub and End Sub, paste If Not Intersect(Target, Me.Range("H5")) Is Nothing Then
4) On the line after "Then" turn off events so that when you call your macro, it does not trigger events and try to run this Worksheet_Change again in a never ending cycle that crashes Excel and/or otherwise messes everything up:
Application.EnableEvents = False
5) Call your macro
Call YourMacroName
6) Turn events back on so the next change (and any/all other events) trigger:
Application.EnableEvents = True
7) End the If block and the Sub:
End If
End Sub
The entire code:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("B3")) Is Nothing Then
Application.EnableEvents = False
Call UpdateAndViewOnly
Application.EnableEvents = True
End If
End Sub
This takes turning events on/off out of the Modules which creates problems and simply lets the change trigger, turns off events, runs your macro and turns events back on.
Use crosstab()
from the tablefunc module.
SELECT * FROM crosstab(
$$SELECT user_id, user_name, rn, email_address
FROM (
SELECT u.user_id, u.user_name, e.email_address
, row_number() OVER (PARTITION BY u.user_id
ORDER BY e.creation_date DESC NULLS LAST) AS rn
FROM usr u
LEFT JOIN email_tbl e USING (user_id)
) sub
WHERE rn < 4
ORDER BY user_id
$$
, 'VALUES (1),(2),(3)'
) AS t (user_id int, user_name text, email1 text, email2 text, email3 text);
I used dollar-quoting for the first parameter, which has no special meaning. It's just convenient if you have to escape single quotes in the query string which is a common case:
Detailed explanation and instructions here:
And in particular, for "extra columns":
The special difficulties here are:
The lack of key names.
-> We substitute with row_number()
in a subquery.
The varying number of emails.
-> We limit to a max. of three in the outer SELECT
and use crosstab()
with two parameters, providing a list of possible keys.
Pay attention to NULLS LAST
in the ORDER BY
.
You may have forgotten to define the Content-Type
header. For example:
return {
statusCode: 200,
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({ items }),

A quite frequent issue is that a batch script is run by double-clicking its icon. Since the hosting Command Prompt (cmd.exe
) instance also terminates as soon as the batch script is finished, it is not possible to read potential output and error messages.
To read such messages, it is very important that you explicitly open a Command Prompt window, manoeuvre to the applicable working directory and run the batch script by typing its path/name.

In my case in the POST
response I want to have the authorization header
because I was having the JWT Token
in it.
So what I read from this post is the header I we want should be added as an Expose Header
from the back-end.
So what I did was added the Authorization
header to my Exposed Header like this in my filter class
.
response.addHeader("Access-Control-Expose-Headers", "Authorization");
response.addHeader("Access-Control-Allow-Headers", "Authorization, X-PINGOTHER, Origin, X-Requested-With, Content-Type, Accept, X-Custom-header");
response.addHeader(HEADER_STRING, TOKEN_PREFIX + token); // HEADER_STRING == Authorization
And at my Angular Side
In the Component.
this.authenticationService.login(this.f.email.value, this.f.password.value)
.pipe(first())
.subscribe(
(data: HttpResponse<any>) => {
console.log(data.headers.get('authorization'));
},
error => {
this.loading = false;
});
At my Service Side.
return this.http.post<any>(Constants.BASE_URL + 'login', {username: username, password: password},
{observe: 'response' as 'body'})
.pipe(map(user => {
return user;
}));
Perhaps you're not disposing of the previous connection/ result classes from the previous run which means their still hanging around in memory.
The solution i'm using is as follows and allows you to set the active class per php page.
Give each of your menu items a unique class, i use .nav-x
(nav-about, here).
<li class="nav-item nav-about">
<a class="nav-link" href="about.php">About</a>
</li>
At the top of each page (about.php here):
<!-- Navbar Active Class -->
<?php $activeClass = '.nav-about > a'; ?>
Elsewhere (header.php / index.php):
<style>
<?php echo $activeClass; ?> {
color: #fff !important;
}
</style>
Simply change the .nav-about > a
per page, .nav-forum > a
, for example.
If you want different styling (colors etc) for each nav item, just attach the inline styling to that page instead of the index / header page.
You could always try the Synth look & feel. You provide an xml file that acts as a sort of stylesheet, along with any images you want to use. The code might look like this:
try {
SynthLookAndFeel synth = new SynthLookAndFeel();
Class aClass = MainFrame.class;
InputStream stream = aClass.getResourceAsStream("\\default.xml");
if (stream == null) {
System.err.println("Missing configuration file");
System.exit(-1);
}
synth.load(stream, aClass);
UIManager.setLookAndFeel(synth);
} catch (ParseException pe) {
System.err.println("Bad configuration file");
pe.printStackTrace();
System.exit(-2);
} catch (UnsupportedLookAndFeelException ulfe) {
System.err.println("Old JRE in use. Get a new one");
System.exit(-3);
}
From there, go on and add your JButton like you normally would. The only change is that you use the setName(string) method to identify what the button should map to in the xml file.
The xml file might look like this:
<synth>
<style id="button">
<font name="DIALOG" size="12" style="BOLD"/>
<state value="MOUSE_OVER">
<imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
<insets top="2" botton="2" right="2" left="2"/>
</state>
<state value="ENABLED">
<imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
<insets top="2" botton="2" right="2" left="2"/>
</state>
</style>
<bind style="button" type="name" key="dirt"/>
</synth>
The bind element there specifies what to map to (in this example, it will apply that styling to any buttons whose name property has been set to "dirt").
And a couple of useful links:

http://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/synth.html
You can go back to the previous activity by just calling finish() in the activity you are on. Note any code after the finish() call will be run - you can just do a return after calling finish() to fix this.
If you want to return results to activity one then when starting activity two you need:
startActivityForResults(myIntent, MY_REQUEST_CODE);
Inside your called activity you can then get the Intent from the onCreate() parameter or used
getIntent();
To set return a result to activity one then in activity two do
setResult(Activity.RESULT_OK, MyIntentToReturn);
If you have no intent to return then just say
setResult(Activity.RESULT_OK);
If the the activity has bad results you can use Activity.RESULT_CANCELED (this is used by default). Then in activity one you do
onActivityResult(int requestCode, int resultCode, Intent data) {
// Handle the logic for the requestCode, resultCode and data returned...
}
To finish activity two use the same methods with finish() as described above with your results already set.
It looks like you are trying to do this?
Iterate and mutate an array using Array.prototype.splice
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'b', 'c', 'b', 'a'];
review.forEach(function(item, index, object) {
if (item === 'a') {
object.splice(index, 1);
}
});
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Which works fine for simple case where you do not have 2 of the same values as adjacent array items, other wise you have this problem.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];
review.forEach(function(item, index, object) {
if (item === 'a') {
object.splice(index, 1);
}
});
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
So what can we do about this problem when iterating and mutating an array? Well the usual solution is to work in reverse. Using ES3 while but you could use for sugar if preferred
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a' ,'a', 'b', 'c', 'b', 'a', 'a'],
index = review.length - 1;
while (index >= 0) {
if (review[index] === 'a') {
review.splice(index, 1);
}
index -= 1;
}
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Ok, but you wanted to use ES5 iteration methods. Well and option would be to use Array.prototype.filter but this does not mutate the original array but creates a new one, so while you can get the correct answer it is not what you appear to have specified.
We could also use ES5 Array.prototype.reduceRight, not for its reducing property by rather its iteration property, i.e. iterate in reverse.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];
review.reduceRight(function(acc, item, index, object) {
if (item === 'a') {
object.splice(index, 1);
}
}, []);
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Or we could use ES5 Array.protoype.indexOf like so.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'],
index = review.indexOf('a');
while (index !== -1) {
review.splice(index, 1);
index = review.indexOf('a');
}
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
But you specifically want to use ES5 Array.prototype.forEach, so what can we do? Well we need to use Array.prototype.slice to make a shallow copy of the array and Array.prototype.reverse so we can work in reverse to mutate the original array.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];
review.slice().reverse().forEach(function(item, index, object) {
if (item === 'a') {
review.splice(object.length - 1 - index, 1);
}
});
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Finally ES6 offers us some further alternatives, where we do not need to make shallow copies and reverse them. Notably we can use Generators and Iterators. However support is fairly low at present.
var pre = document.getElementById('out');
function log(result) {
pre.appendChild(document.createTextNode(result + '\n'));
}
function* reverseKeys(arr) {
var key = arr.length - 1;
while (key >= 0) {
yield key;
key -= 1;
}
}
var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];
for (var index of reverseKeys(review)) {
if (review[index] === 'a') {
review.splice(index, 1);
}
}
log(review);
_x000D_
<pre id="out"></pre>
_x000D_
Something to note in all of the above is that, if you were stripping NaN from the array then comparing with equals is not going to work because in Javascript NaN === NaN
is false. But we are going to ignore that in the solutions as it it yet another unspecified edge case.
So there we have it, a more complete answer with solutions that still have edge cases. The very first code example is still correct but as stated, it is not without issues.
Use make_response
of Flask something like
@app.route("/")
def home():
resp = make_response("hello") #here you could use make_response(render_template(...)) too
resp.headers['Access-Control-Allow-Origin'] = '*'
return resp
From flask docs,
flask.make_response(*args)
Sometimes it is necessary to set additional headers in a view. Because views do not have to return response objects but can return a value that is converted into a response object by Flask itself, it becomes tricky to add headers to it. This function can be called instead of using a return and you will get a response object which you can use to attach headers.
A reference is really a pointer with enough sugar to make it taste nice... ;)
But it also uses a different syntax to pointers, which makes it a bit easier to use references than pointers. Because of this, we don't need &
when calling the function that takes the pointer - the compiler deals with that for you. And you don't need *
to get the content of a reference.
To call a reference an alias is a pretty accurate description - it is "another name for the same thing". So when a
is passed as a reference, we're really passing a
, not a copy of a
- it is done (internally) by passing the address of a
, but you don't need to worry about how that works [unless you are writing your own compiler, but then there are lots of other fun things you need to know when writing your own compiler, that you don't need to worry about when you are just programming].
Note that references work the same way for int
or a class
type.
The main distinction between the two methods is:
loc
gets rows (and/or columns) with particular labels.
iloc
gets rows (and/or columns) at integer locations.
To demonstrate, consider a series s
of characters with a non-monotonic integer index:
>>> s = pd.Series(list("abcdef"), index=[49, 48, 47, 0, 1, 2])
49 a
48 b
47 c
0 d
1 e
2 f
>>> s.loc[0] # value at index label 0
'd'
>>> s.iloc[0] # value at index location 0
'a'
>>> s.loc[0:1] # rows at index labels between 0 and 1 (inclusive)
0 d
1 e
>>> s.iloc[0:1] # rows at index location between 0 and 1 (exclusive)
49 a
Here are some of the differences/similarities between s.loc
and s.iloc
when passed various objects:
<object> | description | s.loc[<object>] |
s.iloc[<object>] |
---|---|---|---|
0 |
single item | Value at index label 0 (the string 'd' ) |
Value at index location 0 (the string 'a' ) |
0:1 |
slice | Two rows (labels 0 and 1 ) |
One row (first row at location 0) |
1:47 |
slice with out-of-bounds end | Zero rows (empty Series) | Five rows (location 1 onwards) |
1:47:-1 |
slice with negative step | Four rows (labels 1 back to 47 ) |
Zero rows (empty Series) |
[2, 0] |
integer list | Two rows with given labels | Two rows with given locations |
s > 'e' |
Bool series (indicating which values have the property) | One row (containing 'f' ) |
NotImplementedError |
(s>'e').values |
Bool array | One row (containing 'f' ) |
Same as loc |
999 |
int object not in index | KeyError |
IndexError (out of bounds) |
-1 |
int object not in index | KeyError |
Returns last value in s |
lambda x: x.index[3] |
callable applied to series (here returning 3rd item in index) | s.loc[s.index[3]] |
s.iloc[s.index[3]] |
loc
's label-querying capabilities extend well-beyond integer indexes and it's worth highlighting a couple of additional examples.
Here's a Series where the index contains string objects:
>>> s2 = pd.Series(s.index, index=s.values)
>>> s2
a 49
b 48
c 47
d 0
e 1
f 2
Since loc
is label-based, it can fetch the first value in the Series using s2.loc['a']
. It can also slice with non-integer objects:
>>> s2.loc['c':'e'] # all rows lying between 'c' and 'e' (inclusive)
c 47
d 0
e 1
For DateTime indexes, we don't need to pass the exact date/time to fetch by label. For example:
>>> s3 = pd.Series(list('abcde'), pd.date_range('now', periods=5, freq='M'))
>>> s3
2021-01-31 16:41:31.879768 a
2021-02-28 16:41:31.879768 b
2021-03-31 16:41:31.879768 c
2021-04-30 16:41:31.879768 d
2021-05-31 16:41:31.879768 e
Then to fetch the row(s) for March/April 2021 we only need:
>>> s3.loc['2021-03':'2021-04']
2021-03-31 17:04:30.742316 c
2021-04-30 17:04:30.742316 d
loc
and iloc
work the same way with DataFrames as they do with Series. It's useful to note that both methods can address columns and rows together.
When given a tuple, the first element is used to index the rows and, if it exists, the second element is used to index the columns.
Consider the DataFrame defined below:
>>> import numpy as np
>>> df = pd.DataFrame(np.arange(25).reshape(5, 5),
index=list('abcde'),
columns=['x','y','z', 8, 9])
>>> df
x y z 8 9
a 0 1 2 3 4
b 5 6 7 8 9
c 10 11 12 13 14
d 15 16 17 18 19
e 20 21 22 23 24
Then for example:
>>> df.loc['c': , :'z'] # rows 'c' and onwards AND columns up to 'z'
x y z
c 10 11 12
d 15 16 17
e 20 21 22
>>> df.iloc[:, 3] # all rows, but only the column at index location 3
a 3
b 8
c 13
d 18
e 23
Sometimes we want to mix label and positional indexing methods for the rows and columns, somehow combining the capabilities of loc
and iloc
.
For example, consider the following DataFrame. How best to slice the rows up to and including 'c' and take the first four columns?
>>> import numpy as np
>>> df = pd.DataFrame(np.arange(25).reshape(5, 5),
index=list('abcde'),
columns=['x','y','z', 8, 9])
>>> df
x y z 8 9
a 0 1 2 3 4
b 5 6 7 8 9
c 10 11 12 13 14
d 15 16 17 18 19
e 20 21 22 23 24
We can achieve this result using iloc
and the help of another method:
>>> df.iloc[:df.index.get_loc('c') + 1, :4]
x y z 8
a 0 1 2 3
b 5 6 7 8
c 10 11 12 13
get_loc()
is an index method meaning "get the position of the label in this index". Note that since slicing with iloc
is exclusive of its endpoint, we must add 1 to this value if we want row 'c' as well.
SET $db['default']['db_debug']
to FALSE instead of TRUE .
$db['default']['db_debug'] = FALSE;
I had the same problem and I created a new listener for it and used in my fragments.
1 - Your activity should have a listener interface and a list of listeners in it
2 - You should implement methods for adding and removing the listeners
3 - You should override the onBackPressed method to check that any of the listeners use the back press or not
public class MainActivity ... {
/**
* Back press listener list. Used for notifying fragments when onBackPressed called
*/
private Stack<BackPressListener> backPressListeners = new Stack<BackPressListener>();
...
/**
* Adding new listener to back press listener stack
* @param backPressListener
*/
public void addBackPressListener(BackPressListener backPressListener) {
backPressListeners.add(backPressListener);
}
/**
* Removing the listener from back press listener stack
* @param backPressListener
*/
public void removeBackPressListener(BackPressListener backPressListener) {
backPressListeners.remove(backPressListener);
}
// Overriding onBackPressed to check that is there any listener using this back press
@Override
public void onBackPressed() {
// checks if is there any back press listeners use this press
for(BackPressListener backPressListener : backPressListeners) {
if(backPressListener.onBackPressed()) return;
}
// if not returns in the loop, calls super onBackPressed
super.onBackPressed();
}
}
4 - Your fragment must implement the interface for back press
5 - You need to add the fragment as a listener for back press
6 - You should return true from onBackPressed if the fragment uses this back press
7 - IMPORTANT - You must remove the fragment from the list onDestroy
public class MyFragment extends Fragment implements MainActivity.BackPressListener {
...
@Override
public void onAttach(Activity activity) {
super.onCreate(savedInstanceState);
// adding the fragment to listener list
((MainActivity) activity).addBackPressListener(this);
}
...
@Override
public void onDestroy() {
super.onDestroy();
// removing the fragment from the listener list
((MainActivity) getActivity()).removeBackPressListener(this);
}
...
@Override
public boolean onBackPressed() {
// you should check that if this fragment is the currently used fragment or not
// if this fragment is not used at the moment you should return false
if(!isThisFragmentVisibleAtTheMoment) return false;
if (isThisFragmentUsingBackPress) {
// do what you need to do
return true;
}
return false;
}
}
There is a Stack used instead of the ArrayList to be able to start from the latest fragment. There may be a problem also while adding fragments to the back stack. So you need to check that the fragment is visible or not while using back press. Otherwise one of the fragments will use the event and latest fragment will not be closed on back press.
I hope this solves the problem for everyone.
I found a solution for converting the files to a .sql
file (you can then import the .sql
file to a server and recover the database), without needing to access the /var
directory, therefore you do not need to be a server admin to do this either.
It does require XAMPP or MAMP installed on your computer.
C:\XAMPP
), and the the sub-directory mysql\data
. The full path should be C:\XAMPP\mysql\data
Inside you will see folders of any other databases you have created. Copy & Paste the folder full of .myd
, .myi
and .frm
files into there. The path to that folder should be
C:\XAMPP\mysql\data\foldername\.mydfiles
Then visit localhost/phpmyadmin
in a browser. Select the database you have just pasted into the mysql\data
folder, and click on Export in the navigation bar. Chooses the export it as a .sql
file. It will then pop up asking where the save the file
And that is it! You (should) now have a .sql
file containing the database that was originally .myd
, .myi
and .frm
files. You can then import it to another server through phpMyAdmin by creating a new database and pressing 'Import' in the navigation bar, then following the steps to import it
add this to your form:
<form id="regform" action="insert.php" method="post">
add this to your function:
<script>
function myFunction() {
var pass1 = document.getElementById("pass1").value;
var pass2 = document.getElementById("pass2").value;
if (pass1 != pass2) {
//alert("Passwords Do not match");
document.getElementById("pass1").style.borderColor = "#E34234";
document.getElementById("pass2").style.borderColor = "#E34234";
}
else {
alert("Passwords Match!!!");
document.getElementById("regForm").submit();
}
}
</script>
Scanner scan = new Scanner(System.in);
int i = scan.nextInt();
Double d = scan.nextDouble();
String newStr = "";
Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
while( charScanner.hasNext() ) {
String c = charScanner.next();
if (c.equalsIgnoreCase("\r")) {
break;
}
else {
newStr += c;
}
}
System.out.println("String: " + newStr);
System.out.println("Int: " + i);
System.out.println("Double: " + d);
This code works fine
This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.
For a simple use of slice
, use my extension to Array Class:
Array.prototype.subarray = function(start, end) {
if (!end) { end = -1; }
return this.slice(start, this.length + 1 - (end * -1));
};
Then:
var bigArr = ["a", "b", "c", "fd", "ze"];
Test1:
bigArr.subarray(1, -1);
< ["b", "c", "fd", "ze"]
Test2:
bigArr.subarray(2, -2);
< ["c", "fd"]
Test3:
bigArr.subarray(2);
< ["c", "fd","ze"]
Might be easier for developers coming from another language (i.e. Groovy).
Python 3 has the facility of launching parallel tasks. This makes our work easier.
It has thread pooling and process pooling.
The following gives an insight:

Not PIL, but imageio.imread
might still be interesting:
import imageio
im = scipy.misc.imread('um_000000.png', flatten=False, mode='RGB')
im = imageio.imread('Figure_1.png', pilmode='RGB')
print(im.shape)
gives
(480, 640, 3)
so it is (height, width, channels). So the pixel at position (x, y)
is
color = tuple(im[y][x])
r, g, b = color
scipy.misc.imread
is deprecated in SciPy 1.0.0 (thanks for the reminder, fbahr!)
Ruby String provides the codepoints
method after 1.9.1.
str = 'hello world'
str.codepoints.to_a
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]
str = "????"
str.codepoints.to_a
=> [20320, 22909, 19990, 30028]
I think you're looking for the stat
function (perldoc -f stat
)
In particular, the 9th field (10th, index #9) of the returned list is the last modify time of the file in seconds since the epoch.
So:
my $last_modified = (stat($fh))[9];
auto
is not a valid value for padding
property, the only thing you can do is take out padding: 0;
from the *
declaration, else simply assign padding
to respective property block.
If you remove padding: 0;
from * {}
than browser will apply default styles to your elements which will give you unexpected cross browser positioning offsets by few pixels, so it is better to assign padding: 0;
using *
and than if you want to override the padding, simply use another rule like
.container p {
padding: 5px;
}
all of above answers would help you but you have to add three ports in the firewall of PC on which SQL Server is installed.
Add new TCP Local port in Windows firewall at port no. 1434
Add new program for SQL Server and select sql server.exe Path: C:\ProgramFiles\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Binn\sqlservr.exe
Add new program for SQL Browser and select sqlbrowser.exe Path: C:\ProgramFiles\Microsoft SQL Server\90\Shared\sqlbrowser.exe
To see the performance difference, try this:
SELECT count(*)
FROM master..sysobjects as A
JOIN tempdb..sysobjects as B
on A.name = B.name
SELECT count(*)
FROM master..sysobjects as A
JOIN tempdb..sysobjects as B
on A.name LIKE B.name
Comparing strings with '=' is much faster.
What I did based on the other answers was
NEWLINE=$'\n'
my_var="__between eggs and bacon__"
echo "spam${NEWLINE}eggs${my_var}bacon${NEWLINE}knight"
# which outputs:
spam
eggs__between eggs and bacon__bacon
knight
Following Macro can also be used to accomplish your task.

Another solution if you want to be certain that this is cross-browser capable is to remove() the tag and then append() or prepend() or in some other way re-add a new instance of the input tag with the same attributes.
<form method="POST" enctype="multipart/form-data">
<label for="fileinput">
<input type="file" name="fileinput" id="fileinput" />
</label>
</form>
$("#fileinput").remove();
$("<input>")
.attr({
type: 'file',
id: 'fileinput',
name: 'fileinput'
})
.appendTo($("label[for='fileinput']"));
There are two alternatives that'll work for sure:
If the above method didn't worked, try the next.
Add the following to build.gradle file at app level

Nice question, a while ago I've experimented a bit with this, but haven't used it a lot because it's still not bulletproof. I divided the plot area into a 32x32 grid and calculated a 'potential field' for the best position of a label for each line according the following rules:
The code was something like this:
import matplotlib.pyplot as plt
import numpy as np
from scipy import ndimage
def my_legend(axis = None):
if axis == None:
axis = plt.gca()
N = 32
Nlines = len(axis.lines)
print Nlines
xmin, xmax = axis.get_xlim()
ymin, ymax = axis.get_ylim()
# the 'point of presence' matrix
pop = np.zeros((Nlines, N, N), dtype=np.float)
for l in range(Nlines):
# get xy data and scale it to the NxN squares
xy = axis.lines[l].get_xydata()
xy = (xy - [xmin,ymin]) / ([xmax-xmin, ymax-ymin]) * N
xy = xy.astype(np.int32)
# mask stuff outside plot
mask = (xy[:,0] >= 0) & (xy[:,0] < N) & (xy[:,1] >= 0) & (xy[:,1] < N)
xy = xy[mask]
# add to pop
for p in xy:
pop[l][tuple(p)] = 1.0
# find whitespace, nice place for labels
ws = 1.0 - (np.sum(pop, axis=0) > 0) * 1.0
# don't use the borders
ws[:,0] = 0
ws[:,N-1] = 0
ws[0,:] = 0
ws[N-1,:] = 0
# blur the pop's
for l in range(Nlines):
pop[l] = ndimage.gaussian_filter(pop[l], sigma=N/5)
for l in range(Nlines):
# positive weights for current line, negative weight for others....
w = -0.3 * np.ones(Nlines, dtype=np.float)
w[l] = 0.5
# calculate a field
p = ws + np.sum(w[:, np.newaxis, np.newaxis] * pop, axis=0)
plt.figure()
plt.imshow(p, interpolation='nearest')
plt.title(axis.lines[l].get_label())
pos = np.argmax(p) # note, argmax flattens the array first
best_x, best_y = (pos / N, pos % N)
x = xmin + (xmax-xmin) * best_x / N
y = ymin + (ymax-ymin) * best_y / N
axis.text(x, y, axis.lines[l].get_label(),
horizontalalignment='center',
verticalalignment='center')
plt.close('all')
x = np.linspace(0, 1, 101)
y1 = np.sin(x * np.pi / 2)
y2 = np.cos(x * np.pi / 2)
y3 = x * x
plt.plot(x, y1, 'b', label='blue')
plt.plot(x, y2, 'r', label='red')
plt.plot(x, y3, 'g', label='green')
my_legend()
plt.show()
And the resulting plot:
@tredder solution with editing applicationHost.config is the one that works if you have several different applications located within virtual directories on IIS.
My case is:
Going into applicationHost.config and manually creating nodes like this:
<location path="XXX/app">
<system.webServer>
<aspNetCore>
<environmentVariables>
<clear />
<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Staging" />
</environmentVariables>
</aspNetCore>
</system.webServer>
</location>
<location path="XXX/api">
<system.webServer>
<aspNetCore>
<environmentVariables>
<clear />
<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Staging" />
</environmentVariables>
</aspNetCore>
</system.webServer>
</location>
and restarting the IIS did the job.
There are two options depending what you want to achieve :
You can use the hidden directive to show or hide an element
<div [hidden]="!edited" class="alert alert-success box-msg" role="alert">
<strong>List Saved!</strong> Your changes has been saved.
</div>
You can use the ngIf control directive to add or remove the element. This is different of the hidden directive because it does not show / hide the element, but it add / remove from the DOM. You can loose unsaved data of the element. It can be the better choice for an edit component that is cancelled.
<div *ngIf="edited" class="alert alert-success box-msg" role="alert">
<strong>List Saved!</strong> Your changes has been saved.
</div>
For you problem of change after 3 seconds, it can be due to incompatibility with setTimeout. Did you include angular2-polyfills.js library in your page ?
Stefan S' comment about the document mode versus browser mode were very pertinent for my problem.
I have the X-UA-Content meta data in the page, but I was client-side testing the browser version via navigator.appVersion
. This test does not reflect the meta data because it is giving the browser mode not the document mode.
The answer for me was to test the document.documentMode
something like:
function IsIE(n)
{
if (navigator.appVersion.indexOf("MSIE ") == -1) return false;
var sDocMode = document.documentMode;
return (isFinite(sDocMode) && sDocMode==n);
}
Now, my meta X-UA-Content tag reflects in my browser test.
Why do I do such a frowned-on thing as test the browser? Speed. Various of my jQuery add-ins, like tablesorter are just too slow on IE6/7, and I want to turn them off. I am not sure that testing for browser features can help me solve this otherwise.
You can do this

They are names for the same standard from two different industries with different naming methods, the guys who make & sell movies and the guys who transfer the movies over the internet. Since 2003: "MPEG 4 Part 10" = "H.264" = "AVC". Before that the relationship was a little looser in that they are not equal but an "MPEG 4 Part 2" decoder can render a stream that's "H.263". The Next standard is "MPEG H Part 2" = "H.265" = "HEVC"
I don't know where the hang comes from, but redirecting (or piping) commands into an interactive ssh is in general a recipe for problems. It is more robust to use the command-to-run-as-a-last-argument style and pass the script on the ssh command line:
ssh user@server 'DEP_ROOT="/home/matthewr/releases"
datestamp=$(date +%Y%m%d%H%M%S)
REL_DIR=$DEP_ROOT"/"$datestamp
if [ ! -d "$DEP_ROOT" ]; then
echo "creating the root directory"
mkdir $DEP_ROOT
fi
mkdir $REL_DIR'
(All in one giant '
-delimited multiline command-line argument).
The pseudo-terminal message is because of your -t
which asks ssh to try to make the environment it runs on the remote machine look like an actual terminal to the programs that run there. Your ssh client is refusing to do that because its own standard input is not a terminal, so it has no way to pass the special terminal APIs onwards from the remote machine to your actual terminal at the local end.
What were you trying to achieve with -t
anyway?
They deprecated getToken() method in the below release notes. Instead, we have to use getInstanceId.
https://firebase.google.com/docs/reference/android/com/google/firebase/iid/FirebaseInstanceId
Task<InstanceIdResult> task = FirebaseInstanceId.getInstance().getInstanceId();
task.addOnSuccessListener(new OnSuccessListener<InstanceIdResult>() {
@Override
public void onSuccess(InstanceIdResult authResult) {
// Task completed successfully
// ...
String fcmToken = authResult.getToken();
}
});
task.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
// Task failed with an exception
// ...
}
});
To handle success and failure in the same listener, attach an OnCompleteListener:
task.addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
@Override
public void onComplete(@NonNull Task<InstanceIdResult> task) {
if (task.isSuccessful()) {
// Task completed successfully
InstanceIdResult authResult = task.getResult();
String fcmToken = authResult.getToken();
} else {
// Task failed with an exception
Exception exception = task.getException();
}
}
});
Also, the FirebaseInstanceIdService Class is deprecated and they came up with onNewToken method in FireBaseMessagingService as replacement for onTokenRefresh,
you can refer to the release notes here, https://firebase.google.com/support/release-notes/android
@Override
public void onNewToken(String s) {
super.onNewToken(s);
Use this code logic to send the info to your server.
//sendRegistrationToServer(s);
}
Well, getting full path is not possible but we can have a temporary path.
Try This:
It'll give you a temporary path not the accurate path, you can use this script if you want to show selected images as in this jsfiddle example(Try it by selectng images as well as other files):-
Here is the code :-
HTML:-
<input type="file" id="i_file" value="">
<input type="button" id="i_submit" value="Submit">
<br>
<img src="" width="200" style="display:none;" />
<br>
<div id="disp_tmp_path"></div>

I closed Visual studio IDE and reopened it by right clicking on the Visual Studio icon and saying "Run as Administrator", Then when I ran the host , It worked!!!
Set content-type and other headers before you write the file out. For small files the content is buffered, and the browser gets the headers first. For big ones the data come first.
For markdown table syntax see:
https://www.markdownguide.org/extended-syntax/#tables
Quick summary:
To quickly understand the syntax used in other answers, it helps to start from a more complete intuitive and easier to remember syntax, and then a minimalized version with the same result.
Basic example:
| Header A | Header B |
| -------------- | -------------- |
| row 1 col 1 | row 1 col 2 |
| row 2 column 1 | row 2 column 2 |
Same result in a more minimalist form (cell widths can vary) :
Header A | Header B
--- | ---
row 1 col 1 | row 1 col 2
row 2 column 1 | row 2 column 2
And more related to the question: side by side images with labels on top:
label 1 | label 2
--- | ---
![](https://...image1.png) | ![](https://...image2.png)
( use :---
, ---:
, and :---:
for (text) alignment in the column, respectively: left, right, center )
Arriving a little late to this discussion but this is my contribution fwiw. I have an IList<Guid> OrderIds
to be converted to a CSV string but following is generic and works unmodified with other types:
string csv = OrderIds.Aggregate(new StringBuilder(),
(sb, v) => sb.Append(v).Append(","),
sb => {if (0 < sb.Length) sb.Length--; return sb.ToString();});
Short and sweet, uses StringBuilder for constructing new string, shrinks StringBuilder length by one to remove last comma and returns CSV string.
I've updated this to use multiple Append()
's to add string + comma. From James' feedback I used Reflector to have a look at StringBuilder.AppendFormat()
. Turns out AppendFormat()
uses a StringBuilder to construct the format string which makes it less efficient in this context than just using multiple Appends()
's.

To convert int32 to string in mongo without creating an array just add "" to your number :-)
db.foo.find( { 'mynum' : { $type : 16 } } ).forEach( function (x) {
x.mynum = x.mynum + ""; // convert int32 to string
db.foo.save(x);
});
You can read from file to map, where the key is the date and skip if the the whole row if the date is already in map
Map<String, List<String>> map = new HashMap<String, List<String>>();
int i = 0;
String lastData = null;
while (s.hasNext()) {
String str = s.next();
if (i % 13 == 0) {
if (map.containsKey(str)) {
//skip the whole row
lastData = null;
} else {
lastData = str;
map.put(lastData, new ArrayList<String>());
}
} else if (lastData != null) {
map.get(lastData).add(str);
}
i++;
}
You need to provide a key.
Try doing this in your ListView Rows if you have a key property:
<TouchableHighlight key={item.key} underlayColor='#dddddd'>
If not, try just adding the item as the key:
<TouchableHighlight key={item} underlayColor='#dddddd'>
If you have a <script>
tag anywhere on your page (even in the HTML, even if it is an empty tag with a src
), then a transition
must be activated by some event (it won't fire automatically when the page loads).
With .Net Core it is now very easy:
You need to do it like this,
void Yourfunction(List<DateTime> dates )
{
}
numpy.ndarray
can contain any type of element, e.g. int
, float
, string
etc. Check the type an do a conversion if neccessary.
Your method (placing script before the closing body tag)
<script>
myFunction()
</script>
</body>
</html>
is a reliable way to support old and new browsers.
Although it's a long time after this question is being asked since I was searching so much for the same problem and couldn't find the extant solutions helpful, I write what fixed my trouble for anyone with the same issue:
The point is, Jupyter should be installed in your virtual environment, meaning, after activating the tensorflow
environment, run the following in the command prompt (in tensorflow
virtual environment):
conda install jupyter
jupyter notebook
and then the jupyter will pop up.
For something very simple and lightweight (slightly modified from here):
from Queue import Queue
from threading import Thread
class Worker(Thread):
"""Thread executing tasks from a given tasks queue"""
def __init__(self, tasks):
Thread.__init__(self)
self.tasks = tasks
self.daemon = True
self.start()
def run(self):
while True:
func, args, kargs = self.tasks.get()
try:
func(*args, **kargs)
except Exception, e:
print e
finally:
self.tasks.task_done()
class ThreadPool:
"""Pool of threads consuming tasks from a queue"""
def __init__(self, num_threads):
self.tasks = Queue(num_threads)
for _ in range(num_threads):
Worker(self.tasks)
def add_task(self, func, *args, **kargs):
"""Add a task to the queue"""
self.tasks.put((func, args, kargs))
def wait_completion(self):
"""Wait for completion of all the tasks in the queue"""
self.tasks.join()
if __name__ == '__main__':
from random import randrange
from time import sleep
delays = [randrange(1, 10) for i in range(100)]
def wait_delay(d):
print 'sleeping for (%d)sec' % d
sleep(d)
pool = ThreadPool(20)
for i, d in enumerate(delays):
pool.add_task(wait_delay, d)
pool.wait_completion()
To support callbacks on task completion you can just add the callback to the task tuple.
Use org.openide.util.Lookup and ClassLoader to dynamically load the Jar plugin, as shown here.
public LoadEngine() {
Lookup ocrengineLookup;
Collection<OCREngine> ocrengines;
Template ocrengineTemplate;
Result ocrengineResults;
try {
//ocrengineLookup = Lookup.getDefault(); this only load OCREngine in classpath of application
ocrengineLookup = Lookups.metaInfServices(getClassLoaderForExtraModule());//this load the OCREngine in the extra module as well
ocrengineTemplate = new Template(OCREngine.class);
ocrengineResults = ocrengineLookup.lookup(ocrengineTemplate);
ocrengines = ocrengineResults.allInstances();//all OCREngines must implement the defined interface in OCREngine. Reference to guideline of implement org.openide.util.Lookup for more information
} catch (Exception ex) {
}
}
public ClassLoader getClassLoaderForExtraModule() throws IOException {
List<URL> urls = new ArrayList<URL>(5);
//foreach( filepath: external file *.JAR) with each external file *.JAR, do as follows
File jar = new File(filepath);
JarFile jf = new JarFile(jar);
urls.add(jar.toURI().toURL());
Manifest mf = jf.getManifest(); // If the jar has a class-path in it's manifest add it's entries
if (mf
!= null) {
String cp =
mf.getMainAttributes().getValue("class-path");
if (cp
!= null) {
for (String cpe : cp.split("\\s+")) {
File lib =
new File(jar.getParentFile(), cpe);
urls.add(lib.toURI().toURL());
}
}
}
ClassLoader cl = ClassLoader.getSystemClassLoader();
if (urls.size() > 0) {
cl = new URLClassLoader(urls.toArray(new URL[urls.size()]), ClassLoader.getSystemClassLoader());
}
return cl;
}
If you have input field like
<input type="file" id="file" name="file" onchange="add(event)"/>
You can get to file content in BLOB format:
function add(event){
var userFile = document.getElementById('file');
userFile.src = URL.createObjectURL(event.target.files[0]);
var data = userFile.src;
}
$("input")[0].disabled = true;
or
$("input")[0].disabled = false;
Possible solutions:
Use nginx on the server as a proxy that will listen to port A and multiplex to port B or C.
If you use AWS you can use the load balancer to redirect the request to specific port based on the host.
I think below function can help
function roundOff(value,round) {
return (parseInt(value * (10 ** (round + 1))) - parseInt(value * (10 ** round)) * 10) > 4 ? (((parseFloat(parseInt((value + parseFloat(1 / (10 ** round))) * (10 ** round))))) / (10 ** round)) : (parseFloat(parseInt(value * (10 ** round))) / ( 10 ** round));
}
usage : roundOff(600.23458,2);
will return 600.23
As I find it best to explain by example and none of the answers seem to do that...
A practical example of using reflections would be a Java Language Server written in Java or a PHP Language Server written in PHP, etc. Language Server gives your IDE abilities like autocomplete, jump to definition, context help, hinting types and more. In order to have all tag names (words that can be autocompleted) to show all the possible matches as you type the Language Server has to inspect everything about the class including doc blocks and private members. For that it needs a reflection of said class.
A different example would be a unit-test of a private method. One way to do so is to create a reflection and change the method's scope to public in the test's set-up phase. Of course one can argue private methods shouldn't be tested directly but that's not the point.

Maps from JDK are not meant for storing data under duplicated keys.
At best new value will override the previous ones.
Worse scenario is exception (e.g when you try to collect it as a stream):
No duplicates:
Stream.of("one").collect(Collectors.toMap(x -> x, x -> x))
Ok. You will get: $2 ==> {one=one}
Duplicated stream:
Stream.of("one", "not one", "surely not one").collect(Collectors.toMap(x -> 1, x -> x))
Exception java.lang.IllegalStateException: Duplicate key 1 (attempted merging values one and not one) | at Collectors.duplicateKeyException (Collectors.java:133) | at Collectors.lambda$uniqKeysMapAccumulator$1 (Collectors.java:180) | at ReduceOps$3ReducingSink.accept (ReduceOps.java:169) | at Spliterators$ArraySpliterator.forEachRemaining (Spliterators.java:948) | at AbstractPipeline.copyInto (AbstractPipeline.java:484) | at AbstractPipeline.wrapAndCopyInto (AbstractPipeline.java:474) | at ReduceOps$ReduceOp.evaluateSequential (ReduceOps.java:913) | at AbstractPipeline.evaluate (AbstractPipeline.java:234) | at ReferencePipeline.collect (ReferencePipeline.java:578) | at (#4:1)
To deal with duplicated keys - use other package, e.g: https://google.github.io/guava/releases/19.0/api/docs/com/google/common/collect/Multimap.html
There is a lot of other implementations dealing with duplicated keys. Those are needed for web (e.g. duplicated cookie keys, Http headers can have same fields, ...)
Good luck! :)
This is the complete way to omit unneeded redirects, too ;)
These rules are intended to be used in .htaccess files, as a RewriteRule in a *:80 VirtualHost entry needs no Conditions.
RewriteEngine on
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]
Eplanations:
RewriteEngine on
==> enable the engine at all
RewriteCond %{HTTPS} off [OR]
==> match on non-https connections, or (not setting [OR] would cause an implicit AND !)
RewriteCond %{HTTP:X-Forwarded-Proto} !https
==> match on forwarded connections (proxy, loadbalancer, etc.) without https
RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]
==> if one of both Conditions match, do the rewrite of the whole URL, sending a 301 to have this 'learned' by the client (some do, some don't) and the L for the last rule.

There seems to be another (rather hacky) way to reuse the router-outlet in one template. This answer is intendend for informational purposes only and the techniques used here should probably not be used in production.
https://stackblitz.com/edit/router-outlet-twice-with-events
The router-outlet is wrapped by an ng-template. The template is updated by listening to events of the router. On every event the template is swapped and re-swapped with an empty placeholder. Without this "swapping" the template would not be updated.
This most definetly is not a recommended approach though, since the whole swapping of two templates seems a bit hacky.
in the controller:
ngOnInit() {
this.router.events.subscribe((routerEvent: Event) => {
console.log(routerEvent);
this.myTemplateRef = this.trigger;
setTimeout(() => {
this.myTemplateRef = this.template;
}, 0);
});
}
in the template:
<div class="would-be-visible-on-mobile-only">
This would be the mobile-layout with a router-outlet (inside a template):
<br>
<ng-container *ngTemplateOutlet="myTemplateRef"></ng-container>
</div>
<hr>
<div class="would-be-visible-on-desktop-only">
This would be the desktop-layout with a router-outlet (inside a template):
<br>
<ng-container *ngTemplateOutlet="myTemplateRef"></ng-container>
</div>
<ng-template #template>
<br>
This is my counter: {{counter}}
inside the template, the router-outlet should follow
<router-outlet>
</router-outlet>
</ng-template>
<ng-template #trigger>
template to trigger changes...
</ng-template>
I was getting the error:
NameError: uninitialized constant
Then I noticed that I had accidentally created a plural model so I went back and renamed the model file to singular and also changed the class name in the model file to singular and that solved it.
I proxy independent Node Express applications through Nginx.
Thus new applications can be easily mounted and I can also run other stuff on the same server at different locations.
Here are more details on my setup with Nginx configuration example:
Deploy multiple Node applications on one web server in subfolders with Nginx
Things get tricky with Node when you need to move your application from from localhost to the internet.
There is no common approach for Node deployment.
Google can find tons of articles on this topic, but I was struggling to find the proper solution for the setup I need.
Basically, I have a web server and I want Node applications to be mounted to subfolders (i.e. http://myhost/demo/pet-project/) without introducing any configuration dependency to the application code.
At the same time I want other stuff like blog to run on the same web server.
Sounds simple huh? Apparently not.
In many examples on the web Node applications either run on port 80 or proxied by Nginx to the root.
Even though both approaches are valid for certain use cases, they do not meet my simple yet a little bit exotic criteria.
That is why I created my own Nginx configuration and here is an extract:
upstream pet_project { server localhost:3000; } server { listen 80; listen [::]:80; server_name frontend; location /demo/pet-project { alias /opt/demo/pet-project/public/; try_files $uri $uri/ @pet-project; } location @pet-project { rewrite /demo/pet-project(.*) $1 break; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $proxy_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://pet_project; proxy_redirect http://pet_project/ /demo/pet-project/; } }
From this example you can notice that I mount my Pet Project Node application running on port 3000 to http://myhost/demo/pet-project.
First Nginx checks if whether the requested resource is a static file available at /opt/demo/pet-project/public/ and if so it serves it as is that is highly efficient, so we do not need to have a redundant layer like Connect static middleware.
Then all other requests are overwritten and proxied to Pet Project Node application, so the Node application does not need to know where it is actually mounted and thus can be moved anywhere purely by configuration.
proxy_redirect is a must to handle Location header properly. This is extremely important if you use res.redirect() in your Node application.
You can easily replicate this setup for multiple Node applications running on different ports and add more location handlers for other purposes.

Here is another solution using only matplotlib.pyplot
and numpy
packages.
It works only for Gaussian fitting. It is based on maximum likelihood estimation and have already been mentioned in this topic.
Here is the corresponding code :
# Python version : 2.7.9
from __future__ import division
import numpy as np
from matplotlib import pyplot as plt
# For the explanation, I simulate the data :
N=1000
data = np.random.randn(N)
# But in reality, you would read data from file, for example with :
#data = np.loadtxt("data.txt")
# Empirical average and variance are computed
avg = np.mean(data)
var = np.var(data)
# From that, we know the shape of the fitted Gaussian.
pdf_x = np.linspace(np.min(data),np.max(data),100)
pdf_y = 1.0/np.sqrt(2*np.pi*var)*np.exp(-0.5*(pdf_x-avg)**2/var)
# Then we plot :
plt.figure()
plt.hist(data,30,normed=True)
plt.plot(pdf_x,pdf_y,'k--')
plt.legend(("Fit","Data"),"best")
plt.show()
and here is the output.
In order to make it work, you have to set property GroupName of both radio buttons to the same value:
<asp:RadioButton id="rbMetric" runat="server" GroupName="measurementSystem"></asp:RadioButton>
<asp:RadioButton id="rbUS" runat="server" GroupName="measurementSystem"></asp:RadioButton>
Personally, I prefer to use a RadioButtonList:
<asp:RadioButtonList ID="rblMeasurementSystem" runat="server">
<asp:ListItem Text="Metric" Value="metric" />
<asp:ListItem Text="US" Value="us" />
</asp:RadioButtonList>
Content-Type: application/force-download
means "I, the web server, am going to lie to you (the browser) about what this file is so that you will not treat it as a PDF/Word Document/MP3/whatever and prompt the user to save the mysterious file to disk instead". It is a dirty hack that breaks horribly when the client doesn't do "save to disk".
Use the correct mime type for whatever media you are using (e.g. audio/mpeg
for mp3).
Use the Content-Disposition: attachment; etc etc
header if you want to encourage the client to download it instead of following the default behaviour.
Functions cannot be used to modify base table information, use a stored procedure.
There is no generic type which will tell the compiler that a method returns nothing.
I believe the convention is to use Object when inheriting as a type parameter
OR
Propagate the type parameter up and then let users of your class instantiate using Object and assigning the object to a variable typed using a type-wildcard ?
:
interface B<E>{ E method(); }
class A<T> implements B<T>{
public T method(){
// do something
return null;
}
}
A<?> a = new A<Object>();
Since XML is a text format and images are usually not (except some ancient and archaic formats) there is no really sensible way to do it. Looking at things like ODT or OOXML also shows you that they don't embed images directly into XML.
What you can do, however, is convert it to Base64 or similar and embed it into the XML.
XML's whitespace handling may further complicate things in such cases, though.
You need to override the color:
a { color:red } /* Globally */
/* Each state */
a:visited { text-decoration: none; color:red; }
a:hover { text-decoration: none; color:blue; }
a:focus { text-decoration: none; color:yellow; }
a:hover, a:active { text-decoration: none; color:black }
If you wanted to do this inline and didn't need recursive descent, this might work:
DATA = { u'spam': u'eggs', u'foo': True, u'bar': { u'baz': 97 } }
print DATA
# "{ u'spam': u'eggs', u'foo': True, u'bar': { u'baz': 97 } }"
STRING_DATA = dict([(str(k), v) for k, v in data.items()])
print STRING_DATA
# "{ 'spam': 'eggs', 'foo': True, 'bar': { u'baz': 97 } }"
pt is a derivation (abbreviation) of "point" which historically was used in print type faces where the size was commonly "measured" in "points" where 1 point has an approximate measurement of 1/72 of an inch, and thus a 72 point font would be 1 inch in size.
px is an abbreviation for "pixel" which is a simple "dot" on either a screen or a dot matrix printer or other printer or device which renders in a dot fashion - as opposed to old typewriters which had a fixed size, solid striker which left an imprint of the character by pressing on a ribbon, thus leaving an image of a fixed size.
Closely related to point are the terms "uppercase" and "lowercase" which historically had to do with the selection of the fixed typographical characters where the "captital" characters where placed in a box (case) above the non-captitalized characters which were place in a box below, and thus the "lower" case.
There were different boxes (cases) for different typographical fonts and sizes, but still and "upper" and "lower" case for each of those.
Another term is the "pica" which is a measure of one character in the font, thus a pica is 1/6 of an inch or 12 point units of measure (12/72) of measure.
Strickly speaking the measurement is on computers 4.233mm or 0.166in whereas the old point (American) is 1/72.27 of an inch and French is 4.512mm (0.177in.). Thus my statement of "approximate" regarding the measurements.
Further, typewriters as used in offices, had either and "Elite" or a "Pica" size where the size was 10 and 12 characters per inch repectivly.
Additionally, the "point", prior to standardization was based on the metal typographers "foot" size, the size of the basic footprint of one character, and varied somewhat in size.
Note that a typographical "foot" was originally from a deceased printers actual foot. A typographic foot contains 72 picas or 864 points.
As to CSS use, I prefer to use EM rather than px or pt, thus gaining the advantage of scaling without loss of relative location and size.
EDIT: Just for completeness you can think of EM (em) as an element of measure of one font height, thus 1em for a 12pt font would be the height of that font and 2em would be twice that height. Note that for a 12px font, 2em is 24 pixels. SO 10px is typically 0.63em of a standard font as "most" browsers base on 16px = 1em as a standard font size.
Use a list instead and replace your foreach
loop with a for
loop:
@model IList<BlockedIPViewModel>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@for (var i = 0; i < Model.Count; i++)
{
<tr>
<td>
@Html.HiddenFor(x => x[i].IP)
@Html.CheckBoxFor(x => x[i].Checked)
</td>
<td>
@Html.DisplayFor(x => x[i].IP)
</td>
</tr>
}
<div>
<input type="submit" value="Unblock IPs" />
</div>
}
Alternatively you could use an editor template:
@model IEnumerable<BlockedIPViewModel>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.EditorForModel()
<div>
<input type="submit" value="Unblock IPs" />
</div>
}
and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml
which will automatically be rendered for each element of the collection:
@model BlockedIPViewModel
<tr>
<td>
@Html.HiddenFor(x => x.IP)
@Html.CheckBoxFor(x => x.Checked)
</td>
<td>
@Html.DisplayFor(x => x.IP)
</td>
</tr>
The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article
.
Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.
Let's try this way:
select
a.ip,
a.os,
a.hostname,
a.port,
a.protocol,
b.state
from a
left join b
on a.ip = b.ip
and a.port = b.port /*if you has to filter by columns from right table , then add this condition in ON clause*/
where a.somecolumn = somevalue /*if you have to filter by some column from left table, then add it to where condition*/
So, in where
clause you can filter result set by column from right table only on this way:
...
where b.somecolumn <> (=) null
A Seq is an Iterable that has a defined order of elements. Sequences provide a method apply()
for indexing, ranging from 0 up to the length of the sequence. Seq has many subclasses including Queue, Range, List, Stack, and LinkedList.
A List is a Seq that is implemented as an immutable linked list. It's best used in cases with last-in first-out (LIFO) access patterns.

Encountered the same issue, after downloading a project, in debug mode. Searched for hours without any luck. Following resolved my problem;
Project Properties -> Linker -> Output file -> $(OutDir)$(TargetName)$(TargetExt)
It was previously pointing to a folder that MSVS wasn't running from whilst debugging mode.
EDIT: soon as I posted this I came across: unable to start "program.exe" the system cannot find the file specified vs2008 which explains the same thing.
Using System Preferences:
Step 1: Click the Apple icon (at the top left of the screen) and select System Preferences.
Step 2: Click Network.
Step 3: Select your network connection and then click Advanced.
Step 4: Select the TCP/IP tab and find your gateway IP address listed next to Router.
I was getting this error when running a remote development development machine using Vagrant. None of the above solutions worked because all the files had the correct permissions.
I fixed it by changing config.vm.box = "hasicorp/bionic64"
to config.vm.box = "bento/ubuntu-20.10"
.
These days even if the spec doesn't allow it, it "seems" to still work to embed the button within a <a href...><button ...></a>
tag, FWIW...
The -std=c++14
flag is not supported on GCC 4.8. If you want to use C++14 features you need to compile with -std=c++1y
. Using godbolt.org it appears that the earilest version to support -std=c++14
is GCC 4.9.0 or Clang 3.5.0
You can easily use .replace()
as also previously described. But it is also important to keep in mind that strings are immutable. Hence if you do not assign the change you are making to a variable, then you will not see any change.
Let me explain by;
>>stuff = "bin and small"
>>stuff.replace('and', ',')
>>print(stuff)
"big and small" #no change
To observe the change you want to apply, you can assign same or another variable;
>>stuff = "big and small"
>>stuff = stuff.replace("and", ",")
>>print(stuff)
'big, small'

The popular answer google.maps.event.trigger(map, "resize");
didn't work for me alone.
Here was a trick that assured that the page had loaded and that the map had loaded as well. By setting a listener and listening for the idle state of the map you can then call the event trigger to resize.
$(document).ready(function() {
google.maps.event.addListener(map, "idle", function(){
google.maps.event.trigger(map, 'resize');
});
});
This was my answer that worked for me.
Use the in
keyword without is

If you'd like to check for the non-existence of a character, use not in
:
if "x" not in dog:
print "No!"
An HTML parser should be used for this purpose rather than regular expressions. A Perl program that makes use of HTML::TreeBuilder
:
#!/usr/bin/env perl
use strict;
use warnings;
use HTML::TreeBuilder;
my $tree = HTML::TreeBuilder->new_from_file( \*DATA );
my @elements = $tree->look_down(
sub { defined $_[0]->attr('name') }
);
for (@elements) {
print $_->attr('name'), "\n";
}

Thank you for pointing right direction in domain name validation solutions in other answers. Domain names could be validated in various ways.
If you need to validate IDN domain in it's human readable form, regex \p{L}
will help. This allows to match any character in any language.
Note that last part might contain hyphens too! As punycode encoded Chineese names might have unicode characters in tld.
I've came to solution which will match for example:
Regex is:
^[0-9\p{L}][0-9\p{L}-\.]{1,61}[0-9\p{L}]\.[0-9\p{L}][\p{L}-]*[0-9\p{L}]+$
NOTE: This regexp is quite permissive, as is current domain names allowed character set.
UPDATE: Even more simplified, as a-aA-Z\p{L}
is same as just \p{L}
NOTE2: The only problem is that it will match domains with double dots in it... , like maselk..owski.pl
. If anyone know how to fix this please improve.
I do not like referring to the number, the sybolic name is much more expressive and avoid having to add a comment that could become obsolete over time.
So I'd rather do:
#pylint: disable-msg=too-many-arguments
And I would also recommend to not leave it dangling there: it will stay active until the file ends or it is disabled, whichever comes first.
So better doing:
#pylint: disable-msg=too-many-arguments
code_which_would_trigger_the_msg
#pylint: enable-msg=too-many-arguments
I would also recommend enabling/disabling one single warning/error per line.
You can not serialize a Python 3 'string' to bytes without explict conversion to some encoding.
outfile.write(plaintext.encode('utf-8'))
is possibly what you want. Also this works for both python 2.x and 3.x.
A really simple implementation is:
out = "".join(c for c in asking if c not in ('!','.',':'))
and keep adding any other types of punctuation.
A more efficient way would be
import string
stringIn = "string.with.punctuation!"
out = stringIn.translate(stringIn.maketrans("",""), string.punctuation)
Edit: There is some more discussion on efficiency and other implementations here: Best way to strip punctuation from a string in Python
The following worked for me on Centos 7.4 with PHP 7.1 using remi repository.
First find out which PHP version I have:
[kiat@reporting ~]$ php --version
PHP 7.1.33 (cli) (built: Oct 23 2019 07:28:45) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.1.33, Copyright (c) 1999-2018, by Zend Technologies
Then search for bcmath
extension in remi-php71
repository:
[kiat@reporting ~]$ yum search php71 | grep bcmath
php71-php-bcmath.x86_64 : A module for PHP applications for using the bcmath
php71u-bcmath.x86_64 : A module for PHP applications for using the bcmath
Now install the first matching extension:
[kiat@reporting ~]$ sudo yum --enablerepo=remi-php71 install php-bcmath
Loaded plugins: fastestmirror, langpacks
base | 3.6 kB 00:00
.
.
.
Finally, restart php and nginx:
[kiat@reporting ~]$ sudo systemctl restart php-fpm nginx
add a second target for the UIButton

Microsoft Access and LibreOffice Base can open a spreadsheet as a source and run sql queries on it. That would be the easiest way to run all kinds of queries, and avoid the mess of running macros or writing code.
Excel also has autofilters and data sorting that will accomplish a lot of simple queries like your example. If you need help with those features, Google would be a better source for tutorials than me.
you can swipe the key and the value. For example
String[] k = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil"};
int[] v = {341, 273, 278, 329, 445};
TreeMap<Integer,String>a=new TreeMap();
for (int i = 0; i < k.length; i++)
a.put(v[i],k[i]);
System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
a.remove(a.firstEntry().getKey());
System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
Short answer is, it make sense. Recently this was discussed in ng-conf 2014. Here is the talk on this topic:
We can mock list properly for foreach loop. Please find below code snippet and explanation.
This is my actual class method where I want to create test case by mocking list.
this.nameList
is a list object.
public void setOptions(){
// ....
for (String str : this.nameList) {
str = "-"+str;
}
// ....
}
The foreach loop internally works on iterator, so here we crated mock of iterator.
Mockito framework has facility to return pair of values on particular method call by using Mockito.when().thenReturn()
, i.e. on hasNext()
we pass 1st true and on second call false, so that our loop will continue only two times. On next()
we just return actual return value.
@Test
public void testSetOptions(){
// ...
Iterator<SampleFilter> itr = Mockito.mock(Iterator.class);
Mockito.when(itr.hasNext()).thenReturn(true, false);
Mockito.when(itr.next()).thenReturn(Mockito.any(String.class);
List mockNameList = Mockito.mock(List.class);
Mockito.when(mockNameList.iterator()).thenReturn(itr);
// ...
}
In this way we can avoid sending actual list to test by using mock of list.

I get these results on an AMD Ahtlon 64 X2 Dual Core 4200+ (2.2 GHz):
Test 1 = 2352048 ticks
Test 2 = 614550 ticks
Test 3 = 1354784 ticks
Test 4 = 844519 ticks
Test 5 = 150021 ticks
Test 6 = 192303 ticks
But get these on a AMD FX 8350 Eight Core (4.00 GHz)
Test 1 = 3917354 ticks
Test 2 = 811727 ticks
Test 3 = 2187388 ticks
Test 4 = 1790292 ticks
Test 5 = 241150 ticks
Test 6 = 227738 ticks
So whether or not method 5 or 6 is faster depends on the CPU, I can only surmise this is because the branch prediction in the command processor of the CPU is smarter on the new processor, but I'm not really sure.
I dont have any Intel CPUs, maybe someone could test it for us?
Just wanted to add another simple way someone can sort the the WPF ListView
void SortListView(ListView listView)
{
IEnumerable listView_items = listView.Items.SourceCollection;
List<MY_ITEM_CLASS> listView_items_to_list = listView_items.Cast<MY_ITEM_CLASS>().ToList();
Comparer<MY_ITEM_CLASS> scoreComparer = Comparer<MY_ITEM_CLASS>.Create((first, second) => first.COLUMN_NAME.CompareTo(second.COLUMN_NAME));
listView_items_to_list.Sort(scoreComparer);
listView.ItemsSource = null;
listView.Items.Clear();
listView.ItemsSource = listView_items_to_list;
}
Try this:
static double Evaluate(string expression) {
var loDataTable = new DataTable();
var loDataColumn = new DataColumn("Eval", typeof (double), expression);
loDataTable.Columns.Add(loDataColumn);
loDataTable.Rows.Add(0);
return (double) (loDataTable.Rows[0]["Eval"]);
}
There is nothing wrong with the example you have given. But i must say i believe it's not efficient to store function definitions in a cpp file. I only understand the need to separate the function's declaration and definition.
When used together with explicit class instantiation, the Boost Concept Check Library (BCCL) can help you generate template function code in cpp files.
ASP.NET Core (in my case 3.1) provides us with Constructor injections into Controllers, so you may simply add following constructor:
[Route("api/[controller]")]
[ApiController]
public class TestController : ControllerBase
{
private readonly IConfiguration m_config;
public TestController(IConfiguration config)
{
m_config = config;
}
[HttpGet]
public string Get()
{
//you can get connection string as follows
string connectionString = m_config.GetConnectionString("Default")
}
}
Here what appsettings.json may look like:
{
"ConnectionStrings": {
"Default": "YOUR_CONNECTION_STRING"
}
}
It's working fine try this.Link
UIViewController *top = [UIApplication sharedApplication].keyWindow.rootViewController;
[top presentViewController:secondView animated:YES completion: nil];

The main difference between that and cron is that an exception will kill the daemon for good. You might want to wrap with an exception catcher and logger.
VBA is not VB/VB.NET
The correct reference to use is Do..Loop Statement (VBA). Also see the article Excel VBA For, Do While, and Do Until. One way to write this is:
Do While counter < 20
counter = counter + 1
Loop
(But a For..Next might be more appropriate here.)
Happy coding.

Is trying to assign 0 to function return value which isn't lvalue.
Function return values are not lvalue (no storage for it), so any attempt to assign value to something that is not lvalue result in error.
Best practice to avoid such mistakes in if conditions is to use constant value on left side of comparison, so even if you use "=" instead "==", constant being not lvalue will immediately give error and avoid accidental value assignment and causing false positive if condition.

You can clone the module directly in to your local project.
Start terminal. cd in to your project and then:
npm install https://github.com/repo/npm_module.git --save
This should not affect everyone, but one of the semi-hidden reasons of the repository size being large could be Git submodules.
You might have added one or more submodules, but stopped using it at some time, and some files remained in .git/modules
directory. To make redundant submodule files gone away, see this question.
However, just like the main repository, the other way is to navigate to the submodule directory in .git/modules
, and do a, for example, git gc --aggressive --prune
.
These should have a good impact in the repository size, but as long as you use Git submodules, e.g. especially with large libraries, your repository size should not change drastically.
You can send some flag to stop while loop in server
for example
import socket
s = socket.socket()
s.bind(("localhost", 5000))
s.listen(1)
c,a = s.accept()
filetodown = open("img.png", "wb")
while True:
print("Receiving....")
data = c.recv(1024)
if data == b"DONE":
print("Done Receiving.")
break
filetodown.write(data)
filetodown.close()
c.send("Thank you for connecting.")
c.shutdown(2)
c.close()
s.close()
#Done :)
import socket
s = socket.socket()
s.connect(("localhost", 5000))
filetosend = open("img.png", "rb")
data = filetosend.read(1024)
while data:
print("Sending...")
s.send(data)
data = filetosend.read(1024)
filetosend.close()
s.send(b"DONE")
print("Done Sending.")
print(s.recv(1024))
s.shutdown(2)
s.close()

// Load the bean
$post = R::load($type,$id);
// Get the properties
$props = $post->getProperties();
// Print the JSON-encoded value
print json_encode($props);
This outputs:
{
"id": "13",
"title": "Oliver Twist",
"author": "Charles Dickens"
}
Now take it a step further. If we have an array of beans...
// An array of beans (just an example)
$series = array($post,$post,$post);
...then we could do the following:
Loop through the array with a foreach
loop.
Replace each element (a bean) with an array of the bean's properties.
So this...
foreach ($series as &$val) {
$val = $val->getProperties();
}
print json_encode($series);
...outputs this:
[
{
"id": "13",
"title": "Oliver Twist",
"author": "Charles Dickens"
},
{
"id": "13",
"title": "Oliver Twist",
"author": "Charles Dickens"
},
{
"id": "13",
"title": "Oliver Twist",
"author": "Charles Dickens"
}
]
Hope this helps!

Regarding the suggestion So I would suggest that you use WebClient and investigate the causes of the 30 second delay.
From the answers for the question System.Net.WebClient unreasonably slow
Try setting Proxy = null;
WebClient wc = new WebClient(); wc.Proxy = null;

mysql_real_escape_string() or str_replace() function will help you to solve your problem.
I had the same issue on Ubuntu 18.04. This was what worked for me:
I removed cmdtest
and yarn
sudo apt remove cmdtest
sudo apt remove yarn
Install yarn globally using npm
sudo npm install -g yarn
You need to make sure that the clocks on all your servers are correct. Kerberos errors are normally caused by your server clock being out of sync with your domain.
UPDATE
Failure code 0x12 very specifically means "Clients credentials have been revoked", which means that this error has happened once the account has been disabled, expired, or locked out.
It would be useful to try and find the previous error messages if you think that the account was active - i.e. this error message may not be the root cause, you will have different errors preceding this error, which cause the account to get locked.
Ideally, to get a full answer, you will need to reactivate the account and keep an eye on the logs for an error occurring before the 0x12 error messages.
When hosting your application on another service (like Heroku, Nodejitsu, and AWS), your host may independently configure the process.env.PORT
variable for you; after all, your script runs in their environment.
Amazon's Elastic Beanstalk does this. If you try to set a static port value like 3000
instead of process.env.PORT || 3000
where 3000 is your static setting, then your application will result in a 500 gateway error because Amazon is configuring the port for you.
This is a minimal Express application that will deploy on Amazon's Elastic Beanstalk:
var express = require('express');
var app = express();
app.get('/', function (req, res) {
res.send('Hello World!');
});
// use port 3000 unless there exists a preconfigured port
var port = process.env.PORT || 3000;
app.listen(port);
Deprecated in general means "don't use it".
A deprecated function may or may not work, but it is not guaranteed to work.
Because I fall for it, I would like to drop a note. I found this thread, because I have to rewrite an old sh script to be POSIX compatible. This basically means to circumvent the pipe/subshell problem introduced by POSIX by rewriting code like this:
some_command | read a b c
into:
read a b c << EOF
$(some_command)
EOF
And code like this:
some_command |
while read a b c; do
# something
done
into:
while read a b c; do
# something
done << EOF
$(some_command)
EOF
But the latter does not behave the same on empty input. With the old notation the while loop is not entered on empty input, but in POSIX notation it is! I think it's due to the newline before EOF, which cannot be ommitted. The POSIX code which behaves more like the old notation looks like this:
while read a b c; do
case $a in ("") break; esac
# something
done << EOF
$(some_command)
EOF
In most cases this should be good enough. But unfortunately this still behaves not exactly like the old notation if some_command prints an empty line. In the old notation the while body is executed and in POSIX notation we break in front of the body.
An approach to fix this might look like this:
while read a b c; do
case $a in ("something_guaranteed_not_to_be_printed_by_some_command") break; esac
# something
done << EOF
$(some_command)
echo "something_guaranteed_not_to_be_printed_by_some_command"
EOF
As described in Cast Functions and Operators:
The type for the result can be one of the following values:
BINARY[(N)]
CHAR[(N)]
DATE
DATETIME
DECIMAL[(M[,D])]
SIGNED [INTEGER]
TIME
UNSIGNED [INTEGER]
Therefore, you should use:
SELECT CAST(PROD_CODE AS UNSIGNED) FROM PRODUCT
proxy issue can cause this. IIS webconfig put this in
<defaultProxy useDefaultCredentials="true" enabled="true">
<proxy usesystemdefault="True" />
</defaultProxy>
Try this character set:
[ \t]
This does only match a space or a tabulator.
Well, my solution is sort of hack, but it works and I am using it.
1vw = 1% of viewport width
1vh = 1% of viewport height
1vmin = 1vw or 1vh, whichever is smaller
1vmax = 1vw or 1vh, whichever is larger
h1 {
font-size: 5.9vw;
}
h2 {
font-size: 3.0vh;
}
p {
font-size: 2vmin;
}
One thing these answers lack, and which newbies are probably looking for, is that while it's nice to have an event:
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
// do something
}
It's not going to do anything at all unless you register the event. Put this in the class constructor:
this.FormClosing += Form1_FormClosing;
Interpreting newlines as <br />
used to be a feature of Github-flavored markdown, but the most recent help document no longer lists this feature.
Fortunately, you can do it manually. The easiest way is to ensure that each line ends with two spaces. So, change
a
b
c
into
a__
b__
c
(where _
is a blank space).
Or, you can add explicit <br />
tags.
a <br />
b <br />
c
Use In
instead of =
select * from dbo.books
where isbn in (select isbn from dbo.lending
where act between @fdate and @tdate
and stat ='close'
)
or you can use Exists
SELECT t1.*,t2.*
FROM books t1
WHERE EXISTS ( SELECT * FROM dbo.lending t2 WHERE t1.isbn = t2.isbn and
t2.act between @fdate and @tdate and t2.stat ='close' )
$(document).bind('keypress', function (e) {
console.log(e.which); //or alert(e.which);
});
you should have firbug to see a result in console
This is might not be the answer you are looking for. but you can use charfield to store the path of the file instead of ImageFile. In that way you can programmatically associate uploaded image to field without recreating the file.
Well, Firefox does not support something like that.
In the reference page from Mozilla specifies font-smooth
as CSS property controls the application of anti-aliasing when fonts are rendered, but this property has been removed from this specification and is currently not on the standard track.
This property is only supported in Webkit browsers.
If you want an alternative you can check this:
StandardScaler performs the task of Standardization. Usually a dataset contains variables that are different in scale. For e.g. an Employee dataset will contain AGE column with values on scale 20-70 and SALARY column with values on scale 10000-80000.
As these two columns are different in scale, they are Standardized to have common scale while building machine learning model.
Try this,
<iframe id="testframe" src="about:blank" onload="if (testframe.location.href != 'about:blank') testframe_loaded()"></iframe>
All you need to do then is create the JavaScript function testframe_loaded().
I am not sure I understood your question, but if you write:
mask_data[:3, :3] = 1
mask_data[3:, 3:] = 0
This will make all values of mask data whose x and y indexes are less than 3 to be equal to 1 and all rest to be equal to 0
Try this:
SELECT MIN(id) AS id, title
FROM tbl_countries
GROUP BY title
Adding an answer that exclusively uses the pandas library to read in a .csv file and save as a .xlsx file. This example makes use of pandas.read_csv
(Link to docs) and pandas.dataframe.to_excel
(Link to docs).
The fully reproducible example uses numpy to generate random numbers only, and this can be removed if you would like to use your own .csv file.
import pandas as pd
import numpy as np
# Creating a dataframe and saving as test.csv in current directory
df = pd.DataFrame(np.random.randn(100000, 3), columns=list('ABC'))
df.to_csv('test.csv', index = False)
# Reading in test.csv and saving as test.xlsx
df_new = pd.read_csv('test.csv')
writer = pd.ExcelWriter('test.xlsx')
df_new.to_excel(writer, index = False)
writer.save()
