Your model is null
because the way you're supplying the inputs to your form means the model binder has no way to distinguish between the elements. Right now, this code:
@foreach (var planVM in Model)
{
@Html.Partial("_partialView", planVM)
}
is not supplying any kind of index to those items. So it would repeatedly generate HTML output like this:
<input type="hidden" name="yourmodelprefix.PlanID" />
<input type="hidden" name="yourmodelprefix.CurrentPlan" />
<input type="checkbox" name="yourmodelprefix.ShouldCompare" />
However, as you're wanting to bind to a collection, you need your form elements to be named with an index, such as:
<input type="hidden" name="yourmodelprefix[0].PlanID" />
<input type="hidden" name="yourmodelprefix[0].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[0].ShouldCompare" />
<input type="hidden" name="yourmodelprefix[1].PlanID" />
<input type="hidden" name="yourmodelprefix[1].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[1].ShouldCompare" />
That index is what enables the model binder to associate the separate pieces of data, allowing it to construct the correct model. So here's what I'd suggest you do to fix it. Rather than looping over your collection, using a partial view, leverage the power of templates instead. Here's the steps you'd need to follow:
EditorTemplates
folder inside your view's current folder (e.g. if your view is Home\Index.cshtml
, create the folder Home\EditorTemplates
).PlanCompareViewModel.cshtml
.Now, everything you have in your partial view wants to go in that template:
@model PlanCompareViewModel
<div>
@Html.HiddenFor(p => p.PlanID)
@Html.HiddenFor(p => p.CurrentPlan)
@Html.CheckBoxFor(p => p.ShouldCompare)
<input type="submit" value="Compare"/>
</div>
Finally, your parent view is simplified to this:
@model IEnumerable<PlanCompareViewModel>
@using (Html.BeginForm("ComparePlans", "Plans", FormMethod.Post, new { id = "compareForm" }))
{
<div>
@Html.EditorForModel()
</div>
}
DisplayTemplates
and EditorTemplates
are smart enough to know when they are handling collections. That means they will automatically generate the correct names, including indices, for your form elements so that you can correctly model bind to a collection.
An alternative is to use StreamReader.
public void FunctionName(HttpPostedFileBase file)
{
string result = new StreamReader(file.InputStream).ReadToEnd();
}
Please post your Model Class.
To check the errors in your ModelState
use the following code:
var errors = ModelState
.Where(x => x.Value.Errors.Count > 0)
.Select(x => new { x.Key, x.Value.Errors })
.ToArray();
OR: You can also use
var errors = ModelState.Values.SelectMany(v => v.Errors);
Place a break point at the above line and see what are the errors in your ModelState
.
you make the use of the HTML Helper and have
@using(Html.BeginForm())
{
Username: <input type="text" name="username" /> <br />
Password: <input type="text" name="password" /> <br />
<input type="submit" value="Login">
<input type="submit" value="Create Account"/>
}
or use the Url helper
<form method="post" action="@Url.Action("MyAction", "MyController")" >
Html.BeginForm
has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:
@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
< ... >
}
If you don't specify any arguments, the Html.BeginForm()
will create a POST
form that points to your current controller and current action. As an example, let's say you have a controller called Posts
and an action called Delete
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
return View(model);
}
[HttpPost]
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
if(model != null)
db.DeletePost(id);
return RedirectToView("Index");
}
and your html page would be something like:
<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>
@using(Html.BeginForm())
{
<input type="submit" class="btn btn-danger" value="Delete Post"/>
<text>or</text>
@Url.ActionLink("go to list", "Index")
}
This can happen if you call
.SingleOrDefault()
on an IEnumerable with 2 or more elements.

This may be overkill for this simple problem. But for Try-Do methods in connection with Linq, I tend to use anonymous classes for more expressive code. It is similar to the answers from Olivier Jacot-Descombes and BA TabNabber:
List<int> ints = strings
.Select(idString => new { ParseSuccessful = Int32.TryParse(idString, out var id), Value = id })
.Where(id => id.ParseSuccessful)
.Select(id => id.Value)
.ToList();
This code helped find my problem when I had issue with my Entity VAlidation Erros. It told me the exact problem with my Entity Definition. Try following code where you need to cover storeDB.SaveChanges(); in following try catch block.
try
{
if (TryUpdateModel(theEvent))
{
storeDB.SaveChanges();
return RedirectToAction("Index");
}
}
catch (System.Data.Entity.Validation.DbEntityValidationException dbEx)
{
Exception raise = dbEx;
foreach (var validationErrors in dbEx.EntityValidationErrors)
{
foreach (var validationError in validationErrors.ValidationErrors)
{
string message = string.Format("{0}:{1}",
validationErrors.Entry.Entity.ToString(),
validationError.ErrorMessage);
// raise a new exception nesting
// the current instance as InnerException
raise = new InvalidOperationException(message, raise);
}
}
throw raise;
}
I know that this question was written when MVC3 wasn't out, but for anyone who comes to this question and are using MVC3, you may want the "correct" way to do this.
While I think that doing the whole
Contains("true");
thing is great and clean, and works on all MVC versions, the problem is that it doesn't take culture into account (as if it really matters in the case of a bool).
The "correct" way to figure out the value of a bool, at least in MVC3, is to use the ValueProvider.
var value = (bool)ValueProvider.GetValue("key").ConvertTo(typeof(bool));
I do this in one of my client's sites when I edit permissions:
var allPermissionsBase = Request.Params.AllKeys.Where(x => x.Contains("permission_")).ToList();
var allPermissions = new List<KeyValuePair<int, bool>>();
foreach (var key in allPermissionsBase)
{
// Try to parse the key as int
int keyAsInt;
int.TryParse(key.Replace("permission_", ""), out keyAsInt);
// Try to get the value as bool
var value = (bool)ValueProvider.GetValue(key).ConvertTo(typeof(bool));
}
Now, the beauty of this is you can use this with just about any simple type, and it will even be correct based on the Culture (think money, decimals, etc).
The ValueProvider is what is used when you form your Actions like this:
public ActionResult UpdatePermissions(bool permission_1, bool permission_2)
but when you are trying to dynamically build these lists and check the values, you will never know the Id at compile time, so you have to process them on the fly.
You can use a \r
(carriage return) to return the cursor to the beginning of the line:
printf("hello");
printf("\rbye");
This will print bye on the same line. It won't erase the existing characters though, and because bye is shorter than hello, you will end up with byelo. To erase it you can make your new print longer to overwrite the extra characters:
printf("hello");
printf("\rbye ");
Or, first erase it with a few spaces, then print your new string:
printf("hello");
printf("\r ");
printf("\rbye");
That will print hello, then go to the beginning of the line and overwrite it with spaces, then go back to the beginning again and print bye.
The general answer to your question is that it depends. And you get to decide by specifying what your "Content-Type" is in the HTTP headers.
A value of "application/x-www-form-urlencoded" means that your POST body will need to be URL encoded just like a GET parameter string. A value of "multipart/form-data" means that you'll be using content delimiters and NOT url encoding the content.
This answer has a much more thorough explanation if you'd like more information.
For an answer specific to the PHP libraries you're using (CURL), you should read the documentation here.
Here's the relevant information:
CURLOPT_POST
TRUE to do a regular HTTP POST. This POST is the normal application/x-www-form-urlencoded kind, most commonly used by HTML forms.
CURLOPT_POSTFIELDS
The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. The filetype can be explicitly specified by following the filename with the type in the format ';type=mimetype'. This parameter can either be passed as a urlencoded string like 'para1=val1¶2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data. As of PHP 5.2.0, value must be an array if files are passed to this option with the @ prefix.
I think you are a bit confused on the purpose of custom data attributes. From the w3 spec
Custom data attributes are intended to store custom data private to the page or application, for which there are no more appropriate attributes or elements.
By itself an attribute of data-toggle=value
is basically a key-value pair, in which the key is "data-toggle" and the value is "value".
In the context of Bootstrap, the custom data in the attribute is almost useless without the context that their JavaScript library includes for the data. If you look at the non-minified version of bootstrap.js then you can do a search for "data-toggle" and find how it is being used.
Here is an example of Bootstrap JavaScript code that I copied straight from the file regarding the use of "data-toggle".
Button Toggle
Button.prototype.toggle = function () {
var changed = true
var $parent = this.$element.closest('[data-toggle="buttons"]')
if ($parent.length) {
var $input = this.$element.find('input')
if ($input.prop('type') == 'radio') {
if ($input.prop('checked') && this.$element.hasClass('active')) changed = false
else $parent.find('.active').removeClass('active')
}
if (changed) $input.prop('checked', !this.$element.hasClass('active')).trigger('change')
} else {
this.$element.attr('aria-pressed', !this.$element.hasClass('active'))
}
if (changed) this.$element.toggleClass('active')
}
The context that the code provides shows that Bootstrap is using the data-toggle
attribute as a custom query selector to process the particular element.
From what I see these are the data-toggle options:
You may want to look at the Bootstrap JavaScript documentation to get more specifics of what each do, but basically the data-toggle
attribute toggles the element to active or not.
Got this from Bing. Seems Microsoft has removed some features from the core framework and added it to a separate optional(?) framework component.
To quote from MSDN (http://msdn.microsoft.com/en-us/library/cc656912.aspx)
The .NET Framework 4 Client Profile does not include the following features. You must install the .NET Framework 4 to use these features in your application:
* ASP.NET * Advanced Windows Communication Foundation (WCF) functionality * .NET Framework Data Provider for Oracle * MSBuild for compiling
The best way is probably to use:
:%s/phrase//gc
c
asks for confirmation before each deletion. g
allows multiple replacements to occur on the same line.
You can also just search using /phrase
, select the next match with gn
, and delete it with d
.
Do not use a KeyListener for this as you'll miss much including pasting of text. Also a KeyListener is a very low-level construct and as such, should be avoided in Swing applications.
The solution has been described many times on SO: Use a DocumentFilter. There are several examples of this on this site, some written by me.
For example: using-documentfilter-filterbypass
Also for tutorial help, please look at: Implementing a DocumentFilter.
Edit
For instance:
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.Document;
import javax.swing.text.DocumentFilter;
import javax.swing.text.PlainDocument;
public class DocFilter {
public static void main(String[] args) {
JTextField textField = new JTextField(10);
JPanel panel = new JPanel();
panel.add(textField);
PlainDocument doc = (PlainDocument) textField.getDocument();
doc.setDocumentFilter(new MyIntFilter());
JOptionPane.showMessageDialog(null, panel);
}
}
class MyIntFilter extends DocumentFilter {
@Override
public void insertString(FilterBypass fb, int offset, String string,
AttributeSet attr) throws BadLocationException {
Document doc = fb.getDocument();
StringBuilder sb = new StringBuilder();
sb.append(doc.getText(0, doc.getLength()));
sb.insert(offset, string);
if (test(sb.toString())) {
super.insertString(fb, offset, string, attr);
} else {
// warn the user and don't allow the insert
}
}
private boolean test(String text) {
try {
Integer.parseInt(text);
return true;
} catch (NumberFormatException e) {
return false;
}
}
@Override
public void replace(FilterBypass fb, int offset, int length, String text,
AttributeSet attrs) throws BadLocationException {
Document doc = fb.getDocument();
StringBuilder sb = new StringBuilder();
sb.append(doc.getText(0, doc.getLength()));
sb.replace(offset, offset + length, text);
if (test(sb.toString())) {
super.replace(fb, offset, length, text, attrs);
} else {
// warn the user and don't allow the insert
}
}
@Override
public void remove(FilterBypass fb, int offset, int length)
throws BadLocationException {
Document doc = fb.getDocument();
StringBuilder sb = new StringBuilder();
sb.append(doc.getText(0, doc.getLength()));
sb.delete(offset, offset + length);
if (test(sb.toString())) {
super.remove(fb, offset, length);
} else {
// warn the user and don't allow the insert
}
}
}
Why is this important?
As docs say you have to call setTheme
before any view output. It seems that super.onCreate()
takes part in view
processing.
So, to switch between themes dynamically you simply need to call setTheme
before super.onCreate
like this:
public void onCreate(Bundle savedInstanceState) {
setTheme(android.R.style.Theme);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
}
Another solution.... :-)
import numpy as np
a = [1,2,4]
[1, 2, 4]
b = np.array([a]).T
array([[1], [2], [4]])
I also got the same error but I noticed that I had typed in Foreign*k*ey and not Foreign*K*ey,(capital K) if there is a newbie out there, check out spelling and caps.
The Address property of a cell can get this for you:
MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False)
returns A1
.
The other way around can be done with the Row
and Column
property of Range
:
MsgBox Range("A1").Row & ", " & Range("A1").Column
returns 1,1
.
UPDATE table1 SET (col1, col2) = (col2, col3) FROM othertable WHERE othertable.col1 = 123;
IF NOT EXISTS( SELECT NULL
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'TableName'
AND table_schema = 'SchemaName'
AND column_name = 'ColumnName') BEGIN
ALTER TABLE [SchemaName].[TableName] ADD [ColumnName] int(1) NOT NULL default '0';
END;
An easy way to do it to use Regex match() method :-
For Example
var str ="Hi, Its stacks over flow and stackoverflow Rocks."
// It will check word from beginning to the end of the string
if(str.match(/(^|\W)stack($|\W)/)) {
alert('Word Match');
}else {
alert('Word not found');
}
Check the fiddle
NOTE: For adding case sensitiveness update the regex with /(^|\W)stack($|\W)/i
Thanks
As @Quartz mentioned, you can do something like
stage('Tests') {
parallel(
'Unit Tests': {
container('node') {
sh("npm test --cat=unit")
}
},
'API Tests': {
container('node') {
sh("npm test --cat=acceptance")
}
}
)
}
here is an example for geting a refrence for the root View of a layout , inflating it and using it with setContentView(View view)
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LayoutInflater li=getLayoutInflater();
View rootView=li.inflate(R.layout.activity_main,null);
setContentView(rootView);
}
Manually:
int strlen(string s)

I tried using the dtypes=[datetime, ...] option, but
import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4']
dtypes = [datetime, datetime, str, float]
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)
I encountered the following error:
TypeError: data type not understood
The only change I had to make is to replace datetime with datetime.datetime
import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4']
dtypes = [datetime.datetime, datetime.datetime, str, float]
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)
From the SQL Server 2017 official documentation:
SELECT DATEADD(day, 360, GETDATE());
If you would like to remove the time part of the GETDATE
function, you can do:
SELECT DATEADD(day, 360, CAST(GETDATE() AS DATE));
Using the child selector, I've taken Fadi's incredible answer above and boiled it down to just one CSS rule that I can apply. Now all I have to do is add the contentCentered
class name to elements I want to center:
.contentCentered {_x000D_
text-align: center;_x000D_
}_x000D_
_x000D_
.contentCentered::before {_x000D_
content: '';_x000D_

margin-right: -.25em; /* Adjusts for spacing */_x000D_
}_x000D_
_x000D_
.contentCentered > * {_x000D_

It is pretty old thread but recently i had a similar issue. I was calling a downstream soap service, from a rest service, and I needed to return the xml response coming from the downstream server as is.
So, i ended up adding a SoapMessageContext handler to get the XML response. Then i injected the response xml into servlet context as an attribute.
public boolean handleMessage(SOAPMessageContext context) {
// Get xml response
try {
ServletContext servletContext =
((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getServletContext();
SOAPMessage msg = context.getMessage();
ByteArrayOutputStream out = new ByteArrayOutputStream();
msg.writeTo(out);
String strMsg = new String(out.toByteArray());
servletContext.setAttribute("responseXml", strMsg);
return true;
} catch (Exception e) {
return false;
}
}
Then I have retrieved the xml response string in the service layer.
ServletContext servletContext =
((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getServletContext();
String msg = (String) servletContext.getAttribute("responseXml");
Didn't have chance to test it yet but this approach must be thread safe since it is using the servlet context.
Because python checks in the directories in sequential order starting at the first directory in sys.path
list, till it find the .py
file it was looking for.
Ideally, the current directory or the directory of the script is the first always the first element in the list, unless you modify it, like you did. From documentation -
As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.
So, most probably, you had a .py
file with the same name as the module you were trying to import from, in the current directory (where the script was being run from).
Also, a thing to note about ImportError
s , lets say the import error says -
ImportError: No module named main
- it doesn't mean the main.py
is overwritten, no if that was overwritten we would not be having issues trying to read it. Its some module above this that got overwritten with a .py
or some other file.
Example -
My directory structure looks like -
- test
- shared
- __init__.py
- phtest.py
- testmain.py
Now From testmain.py
, I call from shared import phtest
, it works fine.
Now lets say I introduce a shared.py in test
directory` , example -
- test
- shared
- __init__.py
- phtest.py
- testmain.py
- shared.py
Now when I try to do from shared import phtest
from testmain.py
, I will get the error -
ImportError: cannot import name 'phtest'
As you can see above, the file that is causing the issue is shared.py
, not phtest.py
.
Old question, but since the question asks "using jQuery", I thought I'd provide an option that lets you do this without introducing any vendor dependency.
While there are a lot of templating engines out there, many of their features have fallen in to disfavour recently, with iteration (<% for
), conditionals (<% if
) and transforms (<%= myString | uppercase %>
) seen as microlanguage at best, and anti-patterns at worst. Modern templating practices encourage simply mapping an object to its DOM (or other) representation, e.g. what we see with properties mapped to components in ReactJS (especially stateless components).
One property you can rely on for keeping the HTML for your template next to the rest of your HTML, is by using a non-executing <script>
type
, e.g. <script type="text/template">
. For your case:
<script type="text/template" data-template="listitem">
<a href="${url}" class="list-group-item">
<table>
<tr>
<td><img src="${img}"></td>
<td><p class="list-group-item-text">${title}</p></td>
</tr>
</table>
</a>
</script>
On document load, read your template and tokenize it using a simple String#split
var itemTpl = $('script[data-template="listitem"]').text().split(/\$\{(.+?)\}/g);
Notice that with our token, you get it in the alternating [text, property, text, property]
format. This lets us nicely map it using an Array#map
, with a mapping function:
function render(props) {
return function(tok, i) { return (i % 2) ? props[tok] : tok; };
}
Where props
could look like { url: 'http://foo.com', img: '/images/bar.png', title: 'Lorem Ipsum' }
.
Putting it all together assuming you've parsed and loaded your itemTpl
as above, and you have an items
array in-scope:
$('.search').keyup(function () {
$('.list-items').append(items.map(function (item) {
return itemTpl.map(render(item)).join('');
}));
});
This approach is also only just barely jQuery - you should be able to take the same approach using vanilla javascript with document.querySelector
and .innerHTML
.
A question to ask yourself is: do you really want/need to define templates as HTML files? You can always componentize + re-use a template the same way you'd re-use most things you want to repeat: with a function.
In es7-land, using destructuring, template strings, and arrow-functions, you can write downright pretty looking component functions that can be easily loaded using the $.fn.html
method above.
const Item = ({ url, img, title }) => `
<a href="${url}" class="list-group-item">
<div class="image">
<img src="${img}" />
</div>
<p class="list-group-item-text">${title}</p>
</a>
`;
Then you could easily render it, even mapped from an array, like so:
$('.list-items').html([
{ url: '/foo', img: 'foo.png', title: 'Foo item' },
{ url: '/bar', img: 'bar.png', title: 'Bar item' },
].map(Item).join(''));
Oh and final note: don't forget to sanitize your properties passed to a template, if they're read from a DB, or someone could pass in HTML (and then run scripts, etc.) from your page.
If you're not on exact root of C:/ drive then first of all use cd../.. and then use query mysql -u username -p passsword
using the above lines you can access to mysql database.

Just you need to install a plugin named Indent By Fold
.
You can install this by going through
Plugins -> Plugin Manager -> Show Plugin Manager
. ORPlugins -> Plugins Admin -> chekmark Indent By Fold from list
than install
Then just select the list item and all you need is to type the first word then you got it.
you can use this plugin from a plugin in the menu bar.
With $array being the contents of a PSCustomObject, this works:
$dataGridView1.DataSource=[collections.arraylist]($array)
$dataGridView1.Columns | Foreach-Object{$_.AutoSizeMode = [System.Windows.Forms.DataGridViewAutoSizeColumnMode]::AllCells}
Use DateFormat#parse(String)
:
Date date = dateFormat.parse("2013-10-22");

Try Atatus which provides Advanced Error Tracking and Real User Monitoring for modern web apps.
Let me explain how to get stacktraces that are reasonably complete in all browsers.
Modern Chrome and Opera fully support the HTML 5 draft spec for ErrorEvent and window.onerror
. In both of these browsers you can either use window.onerror
, or bind to the 'error' event properly:
// Only Chrome & Opera pass the error object.
window.onerror = function (message, file, line, col, error) {
console.log(message, "from", error.stack);
// You can send data to your server
// sendError(data);
};
// Only Chrome & Opera have an error attribute on the event.
window.addEventListener("error", function (e) {
console.log(e.error.message, "from", e.error.stack);
// You can send data to your server
// sendError(data);
})
Unfortunately Firefox, Safari and IE are still around and we have to support them too. As the stacktrace is not available in window.onerror
we have to do a little bit more work.
It turns out that the only thing we can do to get stacktraces from errors is to wrap all of our code in a try{ }catch(e){ }
block and then look at e.stack
. We can make the process somewhat easier with a function called wrap that takes a function and returns a new function with good error handling.
function wrap(func) {
// Ensure we only wrap the function once.
if (!func._wrapped) {
func._wrapped = function () {
try{
func.apply(this, arguments);
} catch(e) {
console.log(e.message, "from", e.stack);
// You can send data to your server
// sendError(data);
throw e;
}
}
}
return func._wrapped;
};
This works. Any function that you wrap manually will have good error handling, but it turns out that we can actually do it for you automatically in most cases.
By changing the global definition of addEventListener
so that it automatically wraps the callback we can automatically insert try{ }catch(e){ }
around most code. This lets existing code continue to work, but adds high-quality exception tracking.
var addEventListener = window.EventTarget.prototype.addEventListener;
window.EventTarget.prototype.addEventListener = function (event, callback, bubble) {
addEventListener.call(this, event, wrap(callback), bubble);
}
We also need to make sure that removeEventListener
keeps working. At the moment it won't because the argument to addEventListener
is changed. Again we only need to fix this on the prototype
object:
var removeEventListener = window.EventTarget.prototype.removeEventListener;
window.EventTarget.prototype.removeEventListener = function (event, callback, bubble) {
removeEventListener.call(this, event, callback._wrapped || callback, bubble);
}
You can send error data using image tag as follows
function sendError(data) {
var img = newImage(),
src = 'http://yourserver.com/jserror&data=' + encodeURIComponent(JSON.stringify(data));
img.crossOrigin = 'anonymous';
img.onload = function success() {
console.log('success', data);
};
img.onerror = img.onabort = function failure() {
console.error('failure', data);
};
img.src = src;
}

This is how I did a similar thing. I have tiles that are thumbnails to YouTube videos. When I click the tile, it redirects me to a 'player' page that uses the 'video_id' to render the correct video to the page.
<GridTile
key={video_id}
title={video_title}
containerElement={<Link to={`/player/${video_id}`}/>}

ETA: Sorry, just noticed that you didn't want to use the LINK or REDIRECT components for some reason. Maybe my answer will still help in some way. ; )
The issue with the "one thread per request" model for a server is that they don't scale well for several scenarios compared to the event loop thread model.
Typically, in I/O intensive scenarios the requests spend most of the time waiting for I/O to complete. During this time, in the "one thread per request" model, the resources linked to the thread (such as memory) are unused and memory is the limiting factor. In the event loop model, the loop thread selects the next event (I/O finished) to handle. So the thread is always busy (if you program it correctly of course).
The event loop model as all new things seems shiny and the solution for all issues but which model to use will depend on the scenario you need to tackle. If you have an intensive I/O scenario (like a proxy), the event base model will rule, whereas a CPU intensive scenario with a low number of concurrent processes will work best with the thread-based model.
In the real world most of the scenarios will be a bit in the middle. You will need to balance the real need for scalability with the development complexity to find the correct architecture (e.g. have an event base front-end that delegates to the backend for the CPU intensive tasks. The front end will use little resources waiting for the task result.) As with any distributed system it requires some effort to make it work.
If you are looking for the silver bullet that will fit with any scenario without any effort, you will end up with a bullet in your foot.
fileinput
seems to be for multiple input streams. This is what I would do:
with open("test.txt") as file:
for line in file:
line = line.rstrip()
if line:
print(line)
1.Concatenate the string (space between each string)
Code Snippet :
<?php
$txt1 = "Sachin";
$txt2 = "Tendulkar";
$result = $txt1.$txt2 ;
echo $result. "\n";
?>
Output: SachinTendulkar
2.Concatenate the string where space exists
Code Snippet :
<?php
$txt1 = "Sachin";
$txt2 = "Tendulkar";
$result = $txt1." ".$txt2;
echo $result. "\n";
?>
Output : Sachin Tendulkar
- Concatenate the string using printf function.
Code Snippet :
<?php
$data1 = "Sachin";
$data2 = "Tendulkar";
printf("%s%s\n",$data1, $data2);
printf("%s %s\n",$data1, $data2);
?>
Output:
SachinTendulkar
Sachin Tendulkar
The below code supports in Java 8
//Read file into String
String fileContent=new String(Files.readAlBytes(Paths.get("MyFile.txt")),StandardCharacters.UFT_8);
//Keeping these into list of strings by splitting with a delimiter
List<String> words = Arrays.asList(contents.split("\\PL+"));
int count=0;
for(String x: words){
if(x.length()>1) count++;
}
sop(x);
You can get much more detailed information than the bash built-in time
(which Robert Gamble mentions) using time(1). Normally this is /usr/bin/time
.
Editor's note:
To ensure that you're invoking the external utility time
rather than your shell's time
keyword, invoke it as /usr/bin/time
.
time
is a POSIX-mandated utility, but the only option it is required to support is -p
.
Specific platforms implement specific, nonstandard extensions: -v
works with GNU's time
utility, as demonstrated below (the question is tagged linux); the BSD/macOS implementation uses -l
to produce similar output - see man 1 time
.

When running into this error and reviewing my dataset which appeared to have no missing data, I discovered that a few of my entries had the special character "#" which derailed importing the data. Once I removed the "#" from the offending cells, the data imported without issue.
Yes, the Session object might be null, but only in certain circumstances, which you will only rarely run into:
If you only have code in pages, you won't run into this. Most of my ASP .NET code uses Session without checking for null repeatedly. It is, however, something to think about if you are developing an IHttpModule or otherwise is down in the grittier details of ASP .NET.
In answer to the comment: Whether or not session state is available depends on whether the AcquireRequestState event has run for the request. This is where the session state module does it's work by reading the session cookie and finding the appropiate set of session variables for you.
AcquireRequestState runs before control is handed to your Page. So if you are calling other functionality, including static classes, from your page, you should be fine.
If you have some classes doing initialization logic during startup, for example on the Application_Start event or by using a static constructor, Session state might not be available. It all boils down to whether there is a current request and AcquireRequestState has been run.
Also, should the client have disabled cookies, the Session object will still be available - but on the next request, the user will return with a new empty Session. This is because the client is given a Session statebag if he does not have one already. If the client does not transport the session cookie, we have no way of identifying the client as the same, so he will be handed a new session again and again.
[...] How should Java Comparator class be declared to sort the arrays by their first elements in decreasing order [...]
Here's a complete example using Java 8:
import java.util.*;
public class Test {
public static void main(String args[]) {
int[][] twoDim = { {1, 2}, {3, 7}, {8, 9}, {4, 2}, {5, 3} };
Arrays.sort(twoDim, Comparator.comparingInt(a -> a[0])
.reversed());
System.out.println(Arrays.deepToString(twoDim));
}
}
Output:
[[8, 9], [5, 3], [4, 2], [3, 7], [1, 2]]
For Java 7 you can do:
Arrays.sort(twoDim, new Comparator<int[]>() {
@Override
public int compare(int[] o1, int[] o2) {
return Integer.compare(o2[0], o1[0]);
}
});
If you unfortunate enough to work on Java 6 or older, you'd do:
Arrays.sort(twoDim, new Comparator<int[]>() {
@Override
public int compare(int[] o1, int[] o2) {
return ((Integer) o2[0]).compareTo(o1[0]);
}
});
If you are using a local .mdf file, probably a sync software such Dropbox attempted to sync two log files (.ldf) in two different computers you can delete the log files from the bin Directory and make sure the .mdf properties->Copy to Output Directory ->Copy if newer that will copy the selected DB file and it's log to the bin Directory. !Alert- if your DB file has only changed in the bin Directory all the changes ill be discarded!

To copy a folder file from local to hdfs, you can the below command
hadoop fs -put /path/localpath /path/hdfspath
or
hadoop fs -copyFromLocal /path/localpath /path/hdfspath
You can use jquery for this:
$('body').bind('copy paste',function(e) {
e.preventDefault(); return false;
});

Considering Rails 3:
html_safe
actually "sets the string" as HTML Safe (it's a little more complicated than that, but it's basically it). This way, you can return HTML Safe strings from helpers or models at will.
h
can only be used from within a controller or view, since it's from a helper. It will force the output to be escaped. It's not really deprecated, but you most likely won't use it anymore: the only usage is to "revert" an html_safe
declaration, pretty unusual.
Prepending your expression with raw
is actually equivalent to calling to_s
chained with html_safe
on it, but is declared on a helper, just like h
, so it can only be used on controllers and views.
"SafeBuffers and Rails 3.0" is a nice explanation on how the SafeBuffer
s (the class that does the html_safe
magic) work.
Instead of explicitly defining the path to the interpreter as in /usr/bin/bash/
, by using the env command, the interpreter is searched for and launched from wherever it is first found. This has both upsides and downsides
Add 'r' in starting of path:
path = r"D:\Folder\file.txt"
That works for me.
PHP doesn't provide conventional means for catching and recovering from fatal errors. This is because processing should not typically be recovered after a fatal error. String matching an output buffer (as suggested by the original post the technique described on PHP.net) is definitely ill-advised. It's simply unreliable.
Calling the mail() function from within an error handler method prove to be problematic, too. If you had a lot of errors, your mail server would be loaded with work, and you could find yourself with a gnarly inbox. To avoid this, you might consider running a cron to scan error logs periodically and send notifications accordingly. You might also like to look into system monitoring software, such as Nagios.
To speak to the bit about registering a shutdown function:
It's true that you can register a shutdown function, and that's a good answer.
The point here is that we typically shouldn't try to recover from fatal errors, especially not by using a regular expression against your output buffer. I was responding to the accepted answer, which linked to a suggestion on php.net which has since been changed or removed.
That suggestion was to use a regex against the output buffer during exception handling, and in the case of a fatal error (detected by the matching against whatever configured error text you might be expecting), try to do some sort of recovery or continued processing. That would not be a recommended practice (I believe that's why I can't find the original suggestion, too. I'm either overlooking it, or the php community shot it down).
It might be worth noting that the more recent versions of PHP (around 5.1) seem to call the shutdown function earlier, before the output buffering callback is envoked. In version 5 and earlier, that order was the reverse (the output buffering callback was followed by the shutdown function). Also, since about 5.0.5 (which is much earlier than the questioner's version 5.2.3), objects are unloaded well before a registered shutdown function is called, so you won't be able to rely on your in-memory objects to do much of anything.
So registering a shutdown function is fine, but the sort of tasks that ought to be performed by a shutdown function are probably limited to a handful of gentle shutdown procedures.
The key take-away here is just some words of wisdom for anyone who stumbles upon this question and sees the advice in the originally accepted answer. Don't regex your output buffer.
request.user.get_username()
will return a string of the users email.
request.user.username
will return a method.
How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:
Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.
The method .transpose() converts columns to rows and rows to column, hence you could even write
df.transpose().ix[3]
this.options[this.selectedIndex].innerHTML
should provide you with the "displayed" text of the selected item. this.value
, like you said, merely provides the value of the value
attribute.
Found the solution :
Added table-layout:fixed
to the table. And opened the application in IE mode.
Ok, I found a working solution for this, it consists of using the beforeunload
event and then making the handler return null
. This executes the wanted code without a confirmation box popping-up. It goes something like this:
window.onbeforeunload = closingCode;
function closingCode(){
// do something...
return null;
}
System.out.println
and Log.d
both go to LogCat, not the Console.
You can simply traverse through the object and return if a match is found.
Here is the code:
returnKeyforValue : function() {
var JsonObj= { "one":1, "two":2, "three":3, "four":4, "five":5 };
for (key in JsonObj) {
if(JsonObj[key] === "Keyvalue") {
return key;
}
}
}
You could use head for this.
Use
$ head --lines=-N file > new_file
where N is the number of lines you want to remove from the file.
The contents of the original file minus the last N lines are now in new_file
You can select to an anonymous type, for example
var dataset2 =
(from recordset in entities.processlists
where recordset.ProcessName == processname
select new
{
serverName = recordset.ServerName,
processId = recordset.ProcessID,
username = recordset.Username
}).ToList();
Or you can create a new class that will represent your selection, for example
public class MyDataSet
{
public string ServerName { get; set; }
public string ProcessId { get; set; }
public string Username { get; set; }
}
then you can for example do the following
var dataset2 =
(from recordset in entities.processlists
where recordset.ProcessName == processname
select new MyDataSet
{
ServerName = recordset.ServerName,
ProcessId = recordset.ProcessID,
Username = recordset.Username
}).ToList();

When you are in a custom View, you can use getDimensionPixelSize(R.dimen.dimen_value)
, in my case, I added the margin in LayoutParams created on init
method.
In Kotlin
init {
LayoutInflater.from(context).inflate(R.layout.my_layout, this, true)
layoutParams = LayoutParams(MATCH_PARENT, WRAP_CONTENT).apply {
val margin = resources.getDimensionPixelSize(R.dimen.dimen_value)
setMargins(0, margin, 0, margin)
}
in Java:
public class CustomView extends LinearLayout {
//..other constructors
public CustomView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}
private void init() {
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
int margin = getResources().getDimensionPixelSize(R.dimen.spacing_dime);
params.setMargins(0, margin, 0, margin);
setLayoutParams(params);
}
}
It's important to store the data in a way that it can be retrieved in the languages used. C-language stores in row-major order (all of first row comes first, then all of second row,...) with every index running from 0 to it's dimension-1. So the order of array x[2][3] is x[0][0], x[0][1], x[0][2], x[1][0], x[1][1], x[1][2]. So in C language, x[i][j] is stored the same place as a 1-dimensional array entry x1dim[ i*3 +j]. If the data is stored that way, it is easy to retrieve in C language.
Fortran and MATLAB are different. They store in column-major order (all of first column comes first, then all of second row,...) and every index runs from 1 to it's dimension. So the index order is the reverse of C and all the indices are 1 greater. If you store the data in the C language order, FORTRAN can find X_C_language[i][j] using X_FORTRAN(j+1, i+1). For instance, X_C_language[1][2] is equal to X_FORTRAN(3,2). In 1-dimensional arrays, that data value is at X1dim_C_language[2*Cdim2 + 3], which is the same position as X1dim_FORTRAN(2*Fdim1 + 3 + 1). Remember that Cdim2 = Fdim1 because the order of indices is reversed.
MATLAB is the same as FORTRAN. Ada is the same as C except the indices normally start at 1. Any language will have the indices in one of those C or FORTRAN orders and the indices will start at 0 or 1 and can be adjusted accordingly to get at the stored data.
Sorry if this explanation is confusing, but I think it is accurate and important for a programmer to know.
The simplest answer of all is...
<a href="javascript:alert('You clicked!')">My link</a>
_x000D_
Or to answer the question of calling a javascript function:
<script type="text/javascript">_x000D_
function myFunction(myMessage) {_x000D_
alert(myMessage);_x000D_
}_x000D_
</script>_x000D_
_x000D_
<a href="javascript:myFunction('You clicked!')">My link</a>
_x000D_
Today, I have used this feature, so here's my very fresh real-life example. (I have changed class and method names to generic ones so they won't distract from the actual point.)
I have a method that's meant to accept a Set
of A
objects that I originally wrote with this signature:
void myMethod(Set<A> set)
But it want to actually call it with Set
s of subclasses of A
. But this is not allowed! (The reason for that is, myMethod
could add objects to set
that are of type A
, but not of the subtype that set
's objects are declared to be at the caller's site. So this could break the type system if it were possible.)
Now here come generics to the rescue, because it works as intended if I use this method signature instead:
<T extends A> void myMethod(Set<T> set)
or shorter, if you don't need to use the actual type in the method body:
void myMethod(Set<? extends A> set)
This way, set
's type becomes a collection of objects of the actual subtype of A
, so it becomes possible to use this with subclasses without endangering the type system.
$now = date("Y-m-d H:i:s");
date("Y-m-d H:i:s", strtotime("+1 hours $now"));
var request = require('request');
function updateClient(postData){
var clientServerOptions = {
uri: 'http://'+clientHost+''+clientContext,
body: JSON.stringify(postData),
method: 'POST',
headers: {
'Content-Type': 'application/json'
}
}
request(clientServerOptions, function (error, response) {
console.log(error,response.body);
return;
});
}
For this to work, your server must be something like:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json())
var port = 9000;
app.post('/sample/put/data', function(req, res) {
console.log('receiving data ...');
console.log('body is ',req.body);
res.send(req.body);
});
// start the server
app.listen(port);
console.log('Server started! At http://localhost:' + port);
datamap = eval(input('Provide some data here: '))
means that you actually evaluate the code before you deem it to be unsafe or not. It evaluates the code as soon as the function is called. See also the dangers of eval
.
ast.literal_eval
raises an exception if the input isn't a valid Python datatype, so the code won't be executed if it's not.
Use ast.literal_eval
whenever you need eval
. You shouldn't usually evaluate literal Python statements.
I think that the best solution would be to use Regular expressions. It's cleanest and probably the most effective. Regular Expressions are supported in all commonly used DB engines.
In MySql there is RLIKE
operator so your query would be something like:
SELECT * FROM buckets WHERE bucketname RLIKE 'Stylus|2100'
I'm not very strong in regexp so I hope the expression is ok.
Edit
The RegExp should rather be:
SELECT * FROM buckets WHERE bucketname RLIKE '(?=.*Stylus)(?=.*2100)'
More on MySql regexp support:
http://dev.mysql.com/doc/refman/5.1/en/regexp.html#operator_regexp
Try this, sudo service mysql stop it will stop any other mysql services and then restart xampp
Another way to convert.
If you have string field, you can transform it or its numerical part the following way: add leading zeros to make all integer strings having equal length.
ORDER BY CONCAT( REPEAT( "0", 18 - LENGTH( stringfield ) ) , stringfield )
or order by part of a field something like 'tensymbols13', 'tensymbols1222' etc.
ORDER BY CONCAT( REPEAT( "0", 18 - LENGTH( LEFT( stringfield , 10 ) ) ) , LEFT( stringfield , 10 ) )
In Java, according to the JSSE Reference Guide, there is no default for the keystore
, the default for the truststore
is "jssecacerts, if it exists. Otherwise, cacerts".
A few applications use ~/.keystore
as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).
I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.
The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-"
for a red line, or by explicitely stating the color
argument.
import matplotlib.pyplot as plt
plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line
plt.show()
See also the plot command's documentation.
In case you already have a line with a certain color, you can change that with the lines2D.set_color()
method.
line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")
import matplotlib.pyplot as plt
import pandas as pd
df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line
plt.show()
If you want to change this color later on, you can do so by
plt.gca().get_lines()[0].set_color("black")
This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them
for ax in plt.gcf().axes:
ax.get_lines()[0].set_color("black")
and if you have more lines you can loop over them as well.
(Update: a few years later Google and Qwant "airlines" still send me here when searching for "git non-default ssh port") A probably better way in newer git versions is to use the GIT_SSH_COMMAND ENV.VAR like:
GIT_SSH_COMMAND="ssh -oPort=1234 -i ~/.ssh/myPrivate_rsa.key" \
git clone myuser@myGitRemoteServer:/my/remote/git_repo/path
This has the added advantage of allowing any other ssh suitable option (port, priv.key, IPv6, PKCS#11 device, ...).
Thanks all who attempted to help.
For me this script was helpful. It process only flat JSON and don't take care of types, but automate some routine

You need to configuring JSSE System Properties, specifically point to client certificate store.
Via command line:
java -Djavax.net.ssl.trustStore=truststores/client.ts com.progress.Client
or via Java code:
import java.util.Properties;
...
Properties systemProps = System.getProperties();
systemProps.put("javax.net.ssl.keyStorePassword","passwordForKeystore");
systemProps.put("javax.net.ssl.keyStore","pathToKeystore.ks");
systemProps.put("javax.net.ssl.trustStore", "pathToTruststore.ts");
systemProps.put("javax.net.ssl.trustStorePassword","passwordForTrustStore");
System.setProperties(systemProps);
...

The difference is pretty subtle and if you dont pay much attention then you will keep it using in a wrong way.
Best way to understand the difference between orElse()
and orElseGet()
is that orElse()
will always be executed if the Optional<T>
is null or not, But orElseGet()
will only be executed when Optional<T>
is null.
The dictionary meaning of orElse is :- execute the part when something is not present, but here it contradicts, see the below example:
Optional<String> nonEmptyOptional = Optional.of("Vishwa Ratna");
String value = nonEmptyOptional.orElse(iAmStillExecuted());
public static String iAmStillExecuted(){
System.out.println("nonEmptyOptional is not NULL,still I am being executed");
return "I got executed";
}
Output: nonEmptyOptional is not NULL,still I am being executed
Optional<String> emptyOptional = Optional.ofNullable(null);
String value = emptyOptional.orElse(iAmStillExecuted());
public static String iAmStillExecuted(){
System.out.println("emptyOptional is NULL, I am being executed, it is normal as
per dictionary");
return "I got executed";
}
Output: emptyOptional is NULL, I am being executed, it is normal as per dictionary
For
orElseGet()
, The method goes as per dictionary meaning, TheorElseGet()
part will be executed only when the Optional is null.
Benchmarks:
+--------------------+------+-----+------------+-------------+-------+
| Benchmark | Mode | Cnt | Score | Error | Units |
+--------------------+------+-----+------------+-------------+-------+
| orElseBenchmark | avgt | 20 | 60934.425 | ± 15115.599 | ns/op |
+--------------------+------+-----+------------+-------------+-------+
| orElseGetBenchmark | avgt | 20 | 3.798 | ± 0.030 | ns/op |
+--------------------+------+-----+------------+-------------+-------+
Remarks:
orElseGet()
has clearly outperformedorElse()
for our particular example.
Hope it clears the doubts of people like me who wants the very basic ground example :)
U can store any value in session like Session["FirstName"] = FirstNameTextBox.Text; but i will suggest u to take as static field in model assign value to it and u can access that field value any where in application. U don't need session. session should be avoided.
public class Employee
{
public int UserId { get; set; }
public string EmailAddress { get; set; }
public static string FullName { get; set; }
}
on controller - Employee.FullName = "ABC"; Now u can access this full Name anywhere in application.
Carriage return is "\r"
. Mind the double quotes!
I think you want "\r\n"
btw to put a line break in your text so it will be rendered correctly in different operating systems.
xcopy src dest /I
REM This assumes dest is a folder and will create it, if it doesnt exists

Actually, we really do not need to import any python library. We can separate the year, month, date using simple SQL. See the below example,
+----------+
| _c0|
+----------+
|1872-11-30|
|1873-03-08|
|1874-03-07|
|1875-03-06|
|1876-03-04|
|1876-03-25|
|1877-03-03|
|1877-03-05|
|1878-03-02|
|1878-03-23|
|1879-01-18|
I have a date column in my data frame which contains the date, month and year and assume I want to extract only the year from the column.
df.createOrReplaceTempView("res")
sqlDF = spark.sql("SELECT EXTRACT(year from `_c0`) FROM res ")
Here I'm creating a temporary view and store the year values using this single line and the output will be,
+-----------------------+
|year(CAST(_c0 AS DATE))|
+-----------------------+
| 1872|
| 1873|
| 1874|
| 1875|
| 1876|
| 1876|
| 1877|
| 1877|
| 1878|
| 1878|
| 1879|
| 1879|
| 1879|
try something like this:
a = buffer[3];
a = a*256 + buffer[2];
a = a*256 + buffer[1];
a = a*256 + buffer[0];
this is assuming that the lowest byte comes first. if the highest byte comes first you might have to swap the indices (go from 0 to 3).
basically for each byte you want to add, you first multiply a by 256 (which equals a shift to the left by 8 bits) and then add the new byte.
I think your solution would be the standard way, but - as you noted yourself - it is probably not the fastest way possible.
You may look at GNU Trove. That is a library which contains all sorts of fast primitive Collections. Your example would use a TObjectIntHashMap which has a method adjustOrPutValue which does exactly what you want.
(city + ', ' + state + ' ' + zip) as ctstzip for select
(city + ', ' + state + ' ' + zip) for insert
Only cast or convert if any field type is different from others.
On insert the value needs to be in the correct spot you need it be inserted. Using "as" will give you an error.
i.e.
Insert into testtable (ctstzip) Values ((city + ', ' + state + ' ' + zip))

I am not sure if you can grab that IP from code that runs on the local machine.
You can however build code that runs on a website, say in JSP, and then use something that returns the IP of where the request came from:
request.getRemoteAddr()
Or simply use already-existing services that do this, then parse the answer from the service to find out the IP.
Use a webservice like AWS and others
import java.net.*;
import java.io.*;
URL whatismyip = new URL("http://checkip.amazonaws.com");
BufferedReader in = new BufferedReader(new InputStreamReader(
whatismyip.openStream()));
String ip = in.readLine(); //you get the IP as a String
System.out.println(ip);
Richard's answer is correct. Alternatively you can also create a MappingJsonFactory
(in org.codehaus.jackson.map
) which knows where to find ObjectMapper
. The error you got was because the regular JsonFactory
(from core
package) has no dependency to ObjectMapper
(which is in the mapper
package).
But usually you just use ObjectMapper
and do not worry about JsonParser
or other low level components -- they will just be needed if you want to data-bind parts of stream, or do low-level handling.
Make sure you don't have any undefined classpath variables (like M2_REPO).
this, work for me :
with open('file.json', 'a') as outfile:
outfile.write(json.dumps(data))
outfile.write(",")
outfile.close()
Assuming that you're constrained to using Date
, you can do the following:
Date diff = new Date(d2.getTime() - d1.getTime());
Here you're computing the differences in milliseconds since the "epoch", and creating a new Date object at an offset from the epoch. Like others have said: the answers in the duplicate question are probably better alternatives (if you aren't tied down to Date
).
I am using this, try it in playground. Define the base urls as Struct in Constants

}
}
private func createURLFromParameters(parameters: [String:Any], pathparam: String?) -> URL {
var components = URLComponents()
components.scheme = Constants.APIDetails.APIScheme
components.host = Constants.APIDetails.APIHost
components.path = Constants.APIDetails.APIPath
if let paramPath = pathparam {
components.path = Constants.APIDetails.APIPath + "\(paramPath)"
}
if !parameters.isEmpty {
components.queryItems = [URLQueryItem]()
for (key, value) in parameters {
let queryItem = URLQueryItem(name: key, value: "\(value)")
components.queryItems!.append(queryItem)
}
}
return components.url!
}
let url = createURLFromParameters(parameters: ["fullText" : "true"], pathparam: "IN")
//Result url= https://restcountries.eu/rest/v1/alpha/IN?fullText=true
Just give them the same name throughout the form you are using.

Don't make it an Array if it is not an Array, make it an object:
var saveData = {};
saveData.a = 2;
saveData.c = 1;
// equivalent to...
var saveData = {a: 2, c: 1}
// equivalent to....
var saveData = {};
saveData['a'] = 2;
saveData['c'] = 1;
Doing it the way you are doing it with Arrays is just taking advantage of Javascript's treatment of Arrays and not really the right way of doing it.
If anyone comes here after me, this is the answer that worked for me.

The answer by @.A. Morel I find to be the best easy to understand solution with a small footprint. Just wanted to add on top if you want a smaller code amount this solution which is a modification of Morel works well for not allowing letters of any sort including inputs notorious 'e' character.

let key = Number(inputEvent.key);
return !isNaN(key);

I use grc
(Generic Colouriser), which allows you to colour the output of a number of commands including diff
.
It is a python script which can be wrapped around any command. So instead of invoking diff file1 file2
, you would invoke grc diff file1 file2
to see colourised output. I have aliased diff
to grc diff
to make it easier.

Gantt chart is wrong... First process P3 has arrived so it will execute first. Since the burst time of P3 is 3sec after the completion of P3, processes P2,P4, and P5 has been arrived. Among P2,P4, and P5 the shortest burst time is 1sec for P2, so P2 will execute next. Then P4 and P5. At last P1 will be executed.
Gantt chart for this ques will be:
| P3 | P2 | P4 | P5 | P1 |

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result
, score
and grade
columns so you don't have multiple columns but you will have multiple rows.
Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:
select ratio = col,
[current ratio], [gearing ratio], [performance ratio], total
from
(
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
) d
pivot
(
max(value)
for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;
See SQL Fiddle with Demo. This will give you the result:
| RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO | TOTAL |
|--------|---------------|---------------|-------------------|-----------|
| grade | Good | Good | Satisfactory | Good |
| result | 1.29400 | 0.33840 | 0.04270 | (null) |
| score | 60.00000 | 70.00000 | 50.00000 | 180.00000 |
The problem with VBA is that there are both dynamic and static arrays...
Dynamic Array Example
Dim myDynamicArray() as Variant
Static Array Example
Dim myStaticArray(10) as Variant
Dim myOtherStaticArray(0 To 10) as Variant
Using error handling to check if the array is empty works for a Dynamic Array, but a static array is by definition not empty, there are entries in the array, even if all those entries are empty.
So for clarity's sake, I named my function "IsZeroLengthArray".
Public Function IsZeroLengthArray(ByRef subject() As Variant) As Boolean
'Tell VBA to proceed if there is an error to the next line.
On Error Resume Next
Dim UpperBound As Integer
Dim ErrorNumber As Long
Dim ErrorDescription As String
Dim ErrorSource As String
'If the array is empty this will throw an error because a zero-length
'array has no UpperBound (or LowerBound).
'This only works for dynamic arrays. If this was a static array there
'would be both an upper and lower bound.
UpperBound = UBound(subject)
'Store the Error Number and then clear the Error object
'because we want VBA to treat unintended errors normally
ErrorNumber = Err.Number
ErrorDescription = Err.Description
ErrorSource = Err.Source
Err.Clear
On Error GoTo 0
'Check the Error Object to see if we have a "subscript out of range" error.
'If we do (the number is 9) then we can assume that the array is zero-length.
If ErrorNumber = 9 Then
IsZeroLengthArray = True
'If the Error number is something else then 9 we want to raise
'that error again...
ElseIf ErrorNumber <> 0 Then
Err.Raise ErrorNumber, ErrorSource, ErrorDescription
'If the Error number is 0 then we have no error and can assume that the
'array is not of zero-length
ElseIf ErrorNumber = 0 Then
IsZeroLengthArray = False
End If
End Function
I hope that this helps others as it helped me.
Your printf

You can easily change default remote for branches all at once simple using this command
git push -u <remote_name> --all
First shift the column:
df['gdp'] = df['gdp'].shift(-1)
Second remove the last row which contains an NaN Cell:
df = df[:-1]
Third reset the index:
df = df.reset_index(drop=True)
From the help (if /?
):
The ELSE clause must occur on the same line as the command after the IF. For example: IF EXIST filename. ( del filename. ) ELSE ( echo filename. missing. ) The following would NOT work because the del command needs to be terminated by a newline: IF EXIST filename. del filename. ELSE echo filename. missing Nor would the following work, since the ELSE command must be on the same line as the end of the IF command: IF EXIST filename. del filename. ELSE echo filename. missing

Although the accepted answer is correct, it doesn't resize Bitmap
by keeping the same Aspect Ratio. If you are looking for a method to resize Bitmap
by keeping the same aspect ratio you can use the following utility function. The usage details and explanation of the function are present at this link.
public static Bitmap resizeBitmap(Bitmap source, int maxLength) {
try {
if (source.getHeight() >= source.getWidth()) {
int targetHeight = maxLength;
if (source.getHeight() <= targetHeight) { // if image already smaller than the required height
return source;
}
double aspectRatio = (double) source.getWidth() / (double) source.getHeight();
int targetWidth = (int) (targetHeight * aspectRatio);
Bitmap result = Bitmap.createScaledBitmap(source, targetWidth, targetHeight, false);
if (result != source) {
}
return result;
} else {
int targetWidth = maxLength;
if (source.getWidth() <= targetWidth) { // if image already smaller than the required height
return source;
}
double aspectRatio = ((double) source.getHeight()) / ((double) source.getWidth());
int targetHeight = (int) (targetWidth * aspectRatio);
Bitmap result = Bitmap.createScaledBitmap(source, targetWidth, targetHeight, false);
if (result != source) {
}
return result;
}
}
catch (Exception e)

Call dplyr
package by installing from cran
in r
library(dplyr)
(file)$(colname)<-sub("-",NA,file$colname)
It will convert all the blank cell in a particular column as NA
If the column contains "-", "", 0 like this change it in code according to the type of blank cell
E.g. if I get a blank cell like "" instead of "-", then use this code:
(file)$(colname)<-sub("", NA, file$colname)
You can even set the prof. pic size to its high resolution that is '1080x1080'
replace "150x150" with 1080x1080 and remove /vp/ from the link.
I see Federico you've found solution by yourself. The problem was in two places. Assignations need proper quoting, in your case
SOME_PATH="/$COMPANY/someProject/some path"
is one of possible solutions.
But in shell those quotes are not stored in a memory, so when you want to use this variable, you need to quote it again, for example:
NEW_VAR="$SOME_PATH"
because if not, space will be expanded to command level, like this:
NEW_VAR=/YourCompany/someProject/some path
which is not what you want.

To return a value from a VBScript function, assign the value to the name of the function, like this:
Function getNumber
getNumber = "423"
End Function

To render SVG file you can use Macaw. Also Macaw supports transformations, user events, animation and various effects.
You can render SVG file with zero lines of code. For more info please check this article: Render SVG file with Macaw.

You can always use the stl:
auto min_value = *std::min_element(v.begin(),v.end());
It's 2017 and it IS possible to target specific select options. In my project I have a table with a class="variations", and the select options are in the table cell td="value", and the select has an ID select#pa_color. The option element also has a class option="attached" (among other class tags). If a user is logged in as a wholesale customer, they can see all of the color options. But retail customers are not allowed to purchase 2 color options, so I've disabled them
<option class="attached" disabled>color 1</option>
<option class="attached" disabled>color 2</option>
It took a little logic, but here is how I targeted the disabled select options.
CSS
table.variations td.value select#pa_color option.attached:disabled {
display: none !important;
}
With that, my color options are only visible to wholesale customers.
It appears that tkFileDialog.askdirectory

You might need to Deserialize your anonymous JSON type from the request body.
var jsonBody = HttpContext.Request.Content.ReadAsStringAsync().Result;
ScoreInputModel myDeserializedClass = JsonConvert.DeserializeObject<ScoreInputModel>(jsonBody);
You could also use vbCrLf
which corresponds to Chr(13)
& Chr(10)
.
i'll leave this here since i will need to use it later. It's a source for a small binary compatible tool that will work equally well in assembly, C and C++.

Mock
vs Spy
Mock
is a bare double object. This object has the same methods signatures but realisation is empty and return default value - 0 and null
Spy
is a cloned double object. New object is cloned based on a real object but you have a possibility to mock it
class A {
String foo1() {
foo2();
return "RealString_1";
}
String foo2() {
return "RealString_2";
}
void foo3() { foo4(); }
void foo4() { }
}
@Test
public void testMockA() {
//given
A mockA = Mockito.mock(A.class);
Mockito.when(mockA.foo1()).thenReturn("MockedString");
//when
String result1 = mockA.foo1();
String result2 = mockA.foo2();
//then
assertEquals("MockedString", result1);
assertEquals(null, result2);
//Case 2
//when
mockA.foo3();
//then
verify(mockA).foo3();
verify(mockA, never()).foo4();
}
@Test
public void testSpyA() {
//given
A spyA = Mockito.spy(new A());
Mockito.when(spyA.foo1()).thenReturn("MockedString");
//when
String result1 = spyA.foo1();

If you DELETE the branch after merging it, just be aware that all hyperlinks, URLs, and references of your DELETED branch will be BROKEN.
So it was a simple fix. Just had to move the ng-click
to a scope click handler:
<input id="upload"
type="file"
ng-file-select="onFileSelect($files)"
style="display: none;">
<button type="button"
ng-click="clickUpload()">Upload</button>
$scope.clickUpload = function(){
angular.element('#upload').trigger('click');
};
When git push [$there]
does not say what to push, we have used the
traditional "matching" semantics so far (all your branches were sent
to the remote as long as there already are branches of the same name
over there). In Git 2.0, the default is now the "simple" semantics,
which pushes:
only the current branch to the branch with the same name, and only when the current branch is set to integrate with that remote branch, if you are pushing to the same remote as you fetch from; or
only the current branch to the branch with the same name, if you are pushing to a remote that is not where you usually fetch from.
You can use the configuration variable "push.default" to change this. If you are an old-timer who wants to keep using the "matching" semantics, you can set the variable to "matching", for example. Read the documentation for other possibilities.
When git add -u
and git add -A
are run inside a subdirectory
without specifying which paths to add on the command line, they
operate on the entire tree for consistency with git commit -a
and
other commands (these commands used to operate only on the current
subdirectory). Say git add -u .
or git add -A .
if you want to
limit the operation to the current directory.
git add <path>
is the same as git add -A <path>
now, so that
git add dir/
will notice paths you removed from the directory and
record the removal. In older versions of Git, git add <path>
used
to ignore removals. You can say git add --ignore-removal <path>
to
add only added or modified paths in <path>
, if you really want to.
It's similar to pass
in Python.
One use would be to stub out a function until it gets written:
future_function () { :; }
If you don't care about the difference between an unset variable or a variable with an empty value, you can use the default-value parameter expansion:
foo=${DEPLOY_ENV:-default}
If you do care about the difference, drop the colon
foo=${DEPLOY_ENV-default}
You can also use the -v
operator to explicitly test if a parameter is set.
if [[ ! -v DEPLOY_ENV ]]; then
echo "DEPLOY_ENV is not set"
elif [[ -z "$DEPLOY_ENV" ]]; then
echo "DEPLOY_ENV is set to the empty string"
else
echo "DEPLOY_ENV has the value: $DEPLOY_ENV"

Add an extra apostrophe '
to the MessageFormat
pattern String
to ensure the '
character is displayed
String text =
java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
^
An apostrophe (aka single quote) in a MessageFormat pattern starts a quoted string and is not interpreted on its own. From the javadoc
A single quote itself must be represented by doubled single quotes '' throughout a String.
The String
You\\'re
is equivalent to adding a backslash character to the String
so the only difference will be that You\re
will be produced rather than Youre
. (before double quote solution ''
applied)

If they're actually managed assemblies, you can use ILMerge. For native DLLs, you'll have a bit more work to do.
See also: How can a C++ windows dll be merged into a C# application exe?
Two observations:
You should write
<input type="button" value="button text" />
instead of
<input type="button">button text</input>
You should rename your function. The function click()
is already defined on a button (it simulates a click), and gets a higher priority then your method.
Note that there are a couple of suggestions here that are plain wrong, and you shouldn't spend to much time on them:
onclick="javascript:myfunc()"
. Only use the javascript:
prefix inside the href
attribute of a hyperlink: <a href="javascript:myfunc()">
.onclick="foo()"
and onclick="foo();"
both work just fine.onclick
, onClick
and ONCLICK
all work. It is common practice to write attributes in lowercase: onclick
. note that javascript itself is case sensitive, so if you write document.getElementById("...").onclick = ...
, then it must be all lowercase.I've been told they are the same.
Actually they are documented in the same place under ruby-doc.org:
http://www.ruby-doc.org/core/classes/Array.html#M000249
- ary.collect {|item| block } ? new_ary
- ary.map {|item| block } ? new_ary
- ary.collect ? an_enumerator
- ary.map ? an_enumerator
Invokes block once for each element of self. Creates a new array containing the values returned by the block. See also Enumerable#collect.
If no block is given, an enumerator is returned instead.a = [ "a", "b", "c", "d" ] a.collect {|x| x + "!" } #=> ["a!", "b!", "c!", "d!"] a #=> ["a", "b", "c", "d"]
I can't repro, but I suspect that in your actual code there is a constraint somewhere that T : class
- you need to propagate that to make the compiler happy, for example (hard to say for sure without a repro example):
public class Derived<SomeModel> : Base<SomeModel> where SomeModel : class, IModel

These are SIMD vector processing instruction sets.
Using vector instructions is faster for many tasks; machine learning is such a task.
Quoting the tensorflow installation docs:
To be compatible with as wide a range of machines as possible, TensorFlow defaults to only using SSE4.1 SIMD instructions on x86 machines. Most modern PCs and Macs support more advanced instructions, so if you're building a binary that you'll only be running on your own machine, you can enable these by using
--copt=-march=native
in your bazel build command.

Do not use css3 variables due to support.
I would do the following if you want a pure css solution.
Use color classes with semenatic names.
.bg-primary { background: #880000; }
.bg-secondary { background: #008800; }
.bg-accent { background: #F5F5F5; }
Separate the structure from the skin (OOCSS)
/* Instead of */
h1 {
font-size: 2rem;
line-height: 1.5rem;
color: #8000;
}
/* use this */
h1 {
font-size: 2rem;
line-height: 1.5rem;
}
.bg-primary {
background: #880000;
}
/* This will allow you to reuse colors in your design */
Put these inside a separate css file to change as needed.
You can find strings method like "strings".methods
You can define string as upcase
, downcase
, titleize
.
For Example,
"hii".downcase
"hii".titleize
"hii".upcase

Setting my RequestOperationManager
Response Serializer to HTTPResponseSerializer
fixed the issue.
Objective-C
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
Swift
manager.responseSerializer = AFHTTPResponseSerializer()
Making this change means I don't need to add acceptableContentTypes
to every request I make.
Update:
if (localStorage.hasOwnProperty("username")) {
//
}
Another way, relevant when value is not expected to be empty string, null or any other falsy value:
if (localStorage["username"]) {
//
}
Assigning questionFrame.frame.size.height= screenSize.height * 0.30
will not reflect anything in the view. because it is a get-only property. If you want to change the frame of questionFrame you can use the below code.
questionFrame.frame = CGRect(x: 0, y: 0, width: 0, height: screenSize.height * 0.70)

This is an IndexError
in python, which means that we're trying to access an index which isn't there in the tensor. Below is a very simple example to understand this error.
# create an empty array of dimension `0`
In [14]: arr = np.array([], dtype=np.int64)
# check its shape
In [15]: arr.shape
Out[15]: (0,)
with this array arr
in place, if we now try to assign any value to some index, for example to the index 0
as in the case below
In [16]: arr[0] = 23
Then, we will get an IndexError
, as below:
IndexError Traceback (most recent call last) <ipython-input-16-0891244a3c59> in <module> ----> 1 arr[0] = 23 IndexError: index 0 is out of bounds for axis 0 with size 0
The reason is that we are trying to access an index (here at 0th position), which is not there (i.e. it doesn't exist because we have an array of size 0
).
In [19]: arr.size * arr.itemsize
Out[19]: 0
So, in essence, such an array is useless and cannot be used for storing anything. Thus, in your code, you've to follow the traceback and look for the place where you're creating an array/tensor of size 0
and fix that.

I'd make the field disabled. Then, when the form submits, make it not disabled. In my opinion, this is easier than having to deal with hidden fields.
//disable the field
$("#myFieldID").prop( "disabled", true );
//right before the form submits, we re-enable the fields, to make them submit.
$( "#myFormID" ).submit(function( event ) {
$("#myFieldID").prop( "disabled", false );
});
My rule is simple (I'm beginner too):
.
if you want to pass the parameter (call the function), and $
if there is no parameter yet (compose a function)That is
show $ head [1, 2]
but never:
show . head [1, 2]
maybe something like
$('div#someDiv').css("height", "auto");
You can try editing /etc/php5/fpm/php.ini:
; Old Limit
; memory_limit = 512M
; New Limit
memory_limit = 2048M
You may need to restart nginx
:
sudo systemctl restart nginx
You may also have an infinite loop somewhere. Can you post the code you're calling?
Use Convert.ToString (value, 2)
so in your case
string binValue = Convert.ToString (3, 2);
In my case, I forgot to add my component in the Declaration array of app.module.ts, and voila! the issue was fixed.
Postman doesn't support websocket. Most of the extension and app I had ever seen were not working properly.
Solution which I found
Just login/ open your application in your browser, and open browser console. Then enter your socket event, and press enter.
socket.emit("event_name", {"id":"123"}, (res)=>{console.log(res); });
This will insert a 10 second sleep in between every call to foo()
, which is approximately what you asked for should the call complete quickly.
import time
while True:
foo()
time.sleep(10)
To do other things while your foo()
is being called in a background thread
import time
import sys
import threading
def foo():
sys.stdout.write('({}) foo\n'.format(time.ctime()))
def foo_target():
while True:
foo()
time.sleep(10)
t = threading.Thread(target=foo_target)
t.daemon = True
t.start()
print('doing other things...')
While running Visual Studio 2012 behind a proxy, I received the following error message when checking for extension updates in the Visual Studio Gallery:
The remote server returned an unexpected response: (417) Expectation failed
A look around Google finally revealed a solution here:
Visual Studio 2012 Proxy Settings

Basically, he's saying the fix is to edit your devenv.exe.config file and change this:
<settings>
<ipv6 enabled="true"/>
</settings>
to this:
<settings>
<ipv6 enabled="true"/>
<servicePointManager expect100Continue="false"/>
</settings>
It is an approach to incrementally add the cron job:
ssh USER_NAME@$PRODUCT_IP nohup "echo '*/2 * * * * ping -c2 PRODUCT_NAME.com >> /var/www/html/test.html' | crontab -u USER_NAME -"
You can use robocopy to copy files with an archive flag and reset the attribute. Use /M command line, this is my backup script with few extra tricks.
This script needs NirCmd tool to keep mouse moving so that my machine won't fall into sleep. Script is using a lockfile to tell when backup script is completed and mousemove.bat script is closed. You may leave this part out.
Another is 7-Zip tool for splitting virtualbox files smaller than 4GB files, my destination folder is still FAT32 so this is mandatory. I should use NTFS disk but haven't converted backup disks yet.

Something like this:

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.
Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.
The best documentation you'll find on the topic is the virtual host documentation in the apache manual.
There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.
The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost
line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost
entry for each port.
Assuming you're starting from scratch, this is much simpler than it may seem.
If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.
NameVirtualHost *:80
If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost
directive, and it will be removed in a future version.
Now your vhost definitions:
<VirtualHost *:80>
DocumentRoot "/home/user/site1/"
ServerName site1
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "/home/user/site2/"
ServerName site2
</VirtualHost>
You can run as many sites as you want on the same port. The ServerName
being different is enough to tell Apache which vhost to use. Also, the ServerName
directive is always the domain/hostname and should never include a path.
If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81
The problem was I have 2 instances of Mysql installed and I didn't know the password for both instances.Just check if port 80 is used by any of the programs. This is what I did
1.Quit Skype because it was using port 80.(Please check if port 80 is used by any other program).
2.Search for Mysql services in task manager and stop it.
3.Now delete all the related mysql files.Make sure you delete all the files.
4.Reinstall
If you're testing for all zeros to avoid a warning on another numpy function then wrapping the line in a try, except block will save having to do the test for zeros before the operation you're interested in i.e.
try: # removes output noise for empty slice
mean = np.mean(array)
except:
mean = 0
The max size for a column of type NVARCHAR(MAX)
is 2 GByte of storage.
Since NVARCHAR
uses 2 bytes per character, that's approx. 1 billion characters.
Leo Tolstoj's War and Peace is a 1'440 page book, containing about 600'000 words - so that might be 6 million characters - well rounded up. So you could stick about 166 copies of the entire War and Peace book into each NVARCHAR(MAX)
column.
Is that enough space for your needs? :-)
What might be a handy addition to this is the possibility to change the post-url from the extra button so you can post to different urls with different buttons. This can be achieved by setting the form 'action' property. Here's the code for that when using jQuery:
$('#[href button name]').click(function(e) {
e.preventDefault();
$('#[form name]').attr('action', 'alternateurl.php');
$('#[form name]').submit();
});
The action-attribute has some issues with older jQuery versions, but on the latest you'll be good to go.

In WAMP the files are served by the Apache component (the A in WAMP).
In Apache, by default the files served are located in the subdirectory htdocs
of the installation directory. But this can be changed, and is actually changed when WAMP installs Apache.
The location from where the files are served is named the DocumentRoot
, and is defined using a variable in Apache configuration file. The default value is the subdirectory htdocs
relative to what is named the ServerRoot
directory.
By default the ServerRoot
is the installation directory of Apache. However this can also be redefined into the configuration file, or using the -d
option of the command httpd
which is used to launch Apache. The value in the configuration file overrides the -d
option.
The configuration file is by default conf/httpd.conf
relative to ServerRoot
. But this can be changed using the -f
option of command httpd.
When WAMP installs itself, it modify the default configuration file with DocumentRoot c:/wamp/www/
. The files to be served need to be located here and not in the htdocs
default directory.
You may change this location set by WAMP, either by modifying DocumentRoot
in the default configuration file, or by using one of the two command line options -f
or -d
which point explicitly or implicity to a new configuration file which may hold a different value for DocumentRoot
(in that case the new file needs to contain this definition, but also the rest of the configuration found in the default configuration file).
As the creator of ElasticSearch, maybe I can give you some reasoning on why I went ahead and created it in the first place :).
Using pure Lucene is challenging. There are many things that you need to take care for if you want it to really perform well, and also, its a library, so no distributed support, it's just an embedded Java library that you need to maintain.
In terms of Lucene usability, way back when (almost 6 years now), I created Compass. Its aim was to simplify using Lucene and make everyday Lucene simpler. What I came across time and time again is the requirement to be able to have Compass distributed. I started to work on it from within Compass, by integrating with data grid solutions like GigaSpaces, Coherence, and Terracotta, but it's not enough.
At its core, a distributed Lucene solution needs to be sharded. Also, with the advancement of HTTP and JSON as ubiquitous APIs, it means that a solution that many different systems with different languages can easily be used.
This is why I went ahead and created ElasticSearch. It has a very advanced distributed model, speaks JSON natively, and exposes many advanced search features, all seamlessly expressed through JSON DSL.
Solr is also a solution for exposing an indexing/search server over HTTP, but I would argue that ElasticSearch provides a much superior distributed model and ease of use (though currently lacking on some of the search features, but not for long, and in any case, the plan is to get all Compass features into ElasticSearch). Of course, I am biased, since I created ElasticSearch, so you might need to check for yourself.
As for Sphinx, I have not used it, so I can't comment. What I can refer you is to this thread at Sphinx forum which I think proves the superior distributed model of ElasticSearch.
Of course, ElasticSearch has many more features than just being distributed. It is actually built with a cloud in mind. You can check the feature list on the site.
Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:
If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php
Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an
iframe
embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.
The best solution I created is to simply use google as the ssl proxy...
https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky
Tested and works in firefox.
Other Methods:
Use a Third party such as embed.ly (but it it really only good for well known http APIs).
Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)
https://example.com
That has a iframe linking to...
https://example.com/utilities/redirect.html
Which has a simple js redirect script like...
document.location.href ="http://thenonsslsite.com";
Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.
You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.
Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).
The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.
Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

for i in range (len(a)):
if a[i]==2:
a[i]=123
You can use a for and or while loop; however if u know the builtin Enumerate function, then it is recommended to use Enumerate.1
If you want to select a value based on true / false use
[selected]="opt.selected == true"
<option *ngFor="let opt of question.options" [value]="opt.key" [selected]="opt.selected == true">{{opt.selected+opt.value}}</option>

If you must use a 2d array:
int numOfPairs = 10; String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){ for(int j = 0; j < array[i].length; j++){ array[i] = new String[2]; array[i][0] = "original word"; array[i][1] = "rearranged word"; } }
Does this give you a hint?
My team were experiencing these issues intermittently with long running SSIS packages. This has been happening since Windows server patching.
Our SSIS and SQL servers are on separate VM servers.
Working with our Wintel Servers team we rebooted both servers and for the moment, the problem appears to have gone away.
The engineer has said that they're unsure if the issue is the patches or new VMTools that they updated at the same time. We'll monitor for now and if the timeout problems recur, they'll try rolling back the VMXNET3 driver, first, then if that doesn't work, take off the June Rollup patches.
So for us the issue is nothing to do with our SQL Queries (we're loading billions of new rows so it has to be long running).
To make something like associative array in JavaScript you have to use objects. ?

var name = "name";
var val = 2;

= "9/13/2015"
You don't need to set innerHTML, just by writing

will work.
P.S.
new Date().toDateString()
= "Sun Sep 13 2015"

As many people mentioned, using LD_PRELOAD
to preload library. BTW, you can CHECK if the setting is available by ldd
command.
Example: suppose you need to preload your own libselinux.so.1
.
> ldd /bin/ls
...
libselinux.so.1 => /lib/x86_64-linux-gnu/libselinux.so.1 (0x00007f3927b1d000)
libacl.so.1 => /lib/x86_64-linux-gnu/libacl.so.1 (0x00007f3927914000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f392754f000)
libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.3 (0x00007f3927311000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f392710c000)
/lib64/ld-linux-x86-64.so.2 (0x00007f3927d65000)
libattr.so.1 => /lib/x86_64-linux-gnu/libattr.so.1 (0x00007f3926f07000)
Thus, set your preload environment:
export LD_PRELOAD=/home/patric/libselinux.so.1
Check your library again:
>ldd /bin/ls
...
libselinux.so.1 =>
/home/patric/libselinux.so.1 (0x00007fb9245d8000)
...
You can do this using Ajax. I have a function that I use for something like this:
function ajax(elementID,filename,str,post)
{
var ajax;
if (window.XMLHttpRequest)
{
ajax=new XMLHttpRequest();//IE7+, Firefox, Chrome, Opera, Safari
}
else if (ActiveXObject("Microsoft.XMLHTTP"))
{
ajax=new ActiveXObject("Microsoft.XMLHTTP");//IE6/5
}
else if (ActiveXObject("Msxml2.XMLHTTP"))
{
ajax=new ActiveXObject("Msxml2.XMLHTTP");//other
}
else
{
alert("Error: Your browser does not support AJAX.");
return false;
}
ajax.onreadystatechange=function()
{
if (ajax.readyState==4&&ajax.status==200)
{
document.getElementById(elementID).innerHTML=ajax.responseText;
}
}
if (post==false)
{
ajax.open("GET",filename+str,true);
ajax.send(null);
}
else
{
ajax.open("POST",filename,true);
ajax.setRequestHeader("Content-type","application/x-www-form-urlencoded");
ajax.send(str);
}
return ajax;
}
The first parameter is the element you want to change. The second parameter is the name of the filename you're loading into the element you're changing. The third parameter is the GET or POST data you're using, so for example "total=10000&othernumber=999". The last parameter is true if you want use POST or false if you want to GET.
