By the way, I've just found out this post: http://blogs.msdn.com/b/webtopics/archive/2010/03/19/iis-7-5-how-to-enable-iis-configuration-auditing.aspx it explains how to audit changes on IIS. For those who face similar problems I suggest to turn on auditing and later see why your site stopped working.
MSDocs state this for your scenario:
In order to execute the first time, PackageManagement requires an internet connection to download the Nuget package provider. However, if your computer does not have an internet connection and you need to use the Nuget or PowerShellGet provider, you can download them on another computer and copy them to your target computer. Use the following steps to do this:
Run
Install-PackageProvider -Name NuGet -RequiredVersion 2.8.5.201 -Force
to install the provider from a computer with an internet connection.After the install, you can find the provider installed in
$env:ProgramFiles\PackageManagement\ReferenceAssemblies\\\<ProviderName\>\\\<ProviderVersion\>
or$env:LOCALAPPDATA\PackageManagement\ProviderAssemblies\\\<ProviderName\>\\\<ProviderVersion\>
.Place the folder, which in this case is the Nuget folder, in the corresponding location on your target computer. If your target computer is a Nano server, you need to run Install-PackageProvider from Nano Server to download the correct Nuget binaries.
Restart PowerShell to auto-load the package provider. Alternatively, run
Get-PackageProvider -ListAvailable
to list all the package providers available on the computer. Then useImport-PackageProvider -Name NuGet -RequiredVersion 2.8.5.201
to import the provider to the current Windows PowerShell session.
You could use a list comprehension or a generator expression instead:
', '.join([str(x) for x in list]) # list comprehension
', '.join(str(x) for x in list) # generator expression
I don't know what's the wrong but I solved by creating a directory directly in c drive(c:\dev) instead of from my home folder (c:\users\me\dev). But I don't have to thinks about it. In my case, it is fresh eclipse unziped instance. I am not able to see .matadata folder in eclipse folder. By God grace, I solved.
The reasonable way how to launch apps from HTML is through url schemes. So you can launch email via mailto:
links and irc through irc:
links. Individual apps can implement these schemes, but I'm not sure WinMerge does this.
A more structured way to get this is to use UriBuilder. This avoids direct string manipulation.
var builder = new UriBuilder(Request.Url.Scheme, Request.Url.Host, Request.Url.Port);
You can use the available()
method to ask the stream whether there is any data available at the moment you call it. However, that function isn't guaranteed to work on all types of input streams. That means that you can't use available()
to determine whether a call to read()
will actually block or not.
My understanding is that interfaces are not that necessary in dynamic languages like Python. In Java (or C++ with its abstract base class) interfaces are means for ensuring that e.g. you're passing the right parameter, able to perform set of tasks.
E.g. if you have observer and observable, observable is interested in subscribing objects that supports IObserver interface, which in turn has notify
action. This is checked at compile time.
In Python, there is no such thing as compile time
and method lookups are performed at runtime. Moreover, one can override lookup with __getattr__() or __getattribute__() magic methods. In other words, you can pass, as observer, any object that can return callable on accessing notify
attribute.
This leads me to the conclusion, that interfaces in Python do exist - it's just their enforcement is postponed to the moment in which they are actually used
First of all it's a little bit harder using just counting analysis to tell if your data is unbalanced or not. For example: 1 in 1000 positive observation is just a noise, error or a breakthrough in science? You never know.
So it's always better to use all your available knowledge and choice its status with all wise.
Okay, what if it's really unbalanced?
Once again — look to your data. Sometimes you can find one or two observation multiplied by hundred times. Sometimes it's useful to create this fake one-class-observations.
If all the data is clean next step is to use class weights in prediction model.
So what about multiclass metrics?
In my experience none of your metrics is usually used. There are two main reasons.
First: it's always better to work with probabilities than with solid prediction (because how else could you separate models with 0.9 and 0.6 prediction if they both give you the same class?)
And second: it's much easier to compare your prediction models and build new ones depending on only one good metric.
From my experience I could recommend logloss or MSE (or just mean squared error).
How to fix sklearn warnings?
Just simply (as yangjie noticed) overwrite average
parameter with one of these
values: 'micro'
(calculate metrics globally), 'macro'
(calculate metrics for each label) or 'weighted'
(same as macro but with auto weights).
f1_score(y_test, prediction, average='weighted')
All your Warnings came after calling metrics functions with default average
value 'binary'
which is inappropriate for multiclass prediction.
Good luck and have fun with machine learning!
Edit:
I found another answerer recommendation to switch to regression approaches (e.g. SVR) with which I cannot agree. As far as I remember there is no even such a thing as multiclass regression. Yes there is multilabel regression which is far different and yes it's possible in some cases switch between regression and classification (if classes somehow sorted) but it pretty rare.
What I would recommend (in scope of scikit-learn) is to try another very powerful classification tools: gradient boosting, random forest (my favorite), KNeighbors and many more.
After that you can calculate arithmetic or geometric mean between predictions and most of the time you'll get even better result.
final_prediction = (KNNprediction * RFprediction) ** 0.5
A simpler answer.
function ($quantity) use ($tax, &$total) { .. };
$tax
inside the closure has no external effect, unless it is a pointer, like an object is.&$total
. This way, modifying the value of $total
DOES HAVE an external effect, the original variable's value changes.As @Mytskine pointed out probably the best in-depth explanation is the RFC for closures. (Upvote him for this.)
Those error messages
CMake Error at ... (project):
No CMAKE_C_COMPILER could be found.
-- Configuring incomplete, errors occurred!
See also ".../CMakeFiles/CMakeOutput.log".
See also ".../CMakeFiles/CMakeError.log".
or
CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.
Please set CMAKE_CXX_COMPILER to a valid compiler path or name.
...
-- Configuring incomplete, errors occurred!
just mean that CMake was unable to find your C/CXX compiler to compile a simple test program (one of the first things CMake tries while detecting your build environment).
The steps to find your problem are dependent on the build environment you want to generate. The following tutorials are a collection of answers here on Stack Overflow and some of my own experiences with CMake on Microsoft Windows 7/8/10 and Ubuntu 14.04.
Preconditions
You have a clean build directory (because CMake does cache things from the last try) e.g. as sub-directory of your source tree
Windows cmd.exe
> rmdir /s /q VS2015
> mkdir VS2015
> cd VS2015
Bash shell
$ rm -rf MSYS
$ mkdir MSYS
$ cd MSYS
and make sure your command shell points to your newly created binary output directory.
General things you can/should try
Is CMake able find and run with any/your default compiler? Run without giving a generator
> cmake ..
-- Building for: Visual Studio 14 2015
...
Perfect if it correctly determined the generator to use - like here Visual Studio 14 2015
What was it that actually failed?
In the previous build output directory look at CMakeFiles\CMakeError.log
for any error message that make sense to you or try to open/compile the test project generated at CMakeFiles\[Version]\CompilerIdC
|CompilerIdCXX
directly from the command line (as found in the error log).
CMake can't find Visual Studio
Try to select the correct generator version:
> cmake --help
> cmake -G "Visual Studio 14 2015" ..
If that doesn't help, try to set the Visual Studio environment variables first (the path could vary):
> "c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat"
> cmake ..
or use the Developer Command Prompt for VS2015
short-cut in your Windows Start Menu under All Programs
/Visual Studio 2015
/Visual Studio Tools
(thanks at @Antwane for the hint).
Background: CMake does support all Visual Studio releases and flavors (Express, Community, Professional, Premium, Test, Team, Enterprise, Ultimate, etc.). To determine the location of the compiler it uses a combination of searching the registry (e.g. at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[Version];InstallDir
), system environment variables and - if none of the others did come up with something - plainly try to call the compiler.
CMake can't find GCC (MinGW/MSys)
You start the MSys bash
shell with msys.bat
and just try to directly call gcc
$ gcc
gcc.exe: fatal error: no input files
compilation terminated.
Here it did find gcc
and is complaining that I didn't gave it any parameters to work with.
So the following should work:
$ cmake -G "MSYS Makefiles" ..
-- The CXX compiler identification is GNU 4.8.1
...
$ make
If GCC was not found call export PATH=...
to add your compilers path (see How to set PATH environment variable in CMake script?) and try again.
If it's still not working, try to set the CXX
compiler path directly by exporting it (path may vary)
$ export CC=/c/MinGW/bin/gcc.exe
$ export CXX=/c/MinGW/bin/g++.exe
$ cmake -G "MinGW Makefiles" ..
-- The CXX compiler identification is GNU 4.8.1
...
$ mingw32-make
For more details see How to specify new GCC path for CMake
Note: When using the "MinGW Makefiles" generator you have to use the mingw32-make
program distributed with MinGW
Still not working? That's weird. Please make sure that the compiler is there and it has executable rights (see also preconditions chapter above).
Otherwise the last resort of CMake is to not try any compiler search itself and set CMake's internal variables directly by
$ cmake -DCMAKE_C_COMPILER=/c/MinGW/bin/gcc.exe -DCMAKE_CXX_COMPILER=/c/MinGW/bin/g++.exe ..
For more details see Cmake doesn't honour -D CMAKE_CXX_COMPILER=g++ and Cmake error setting compiler
Alternatively those variables can also be set via cmake-gui.exe
on Windows. See Cmake cannot find compiler
Background: Much the same as with Visual Studio. CMake supports all sorts of GCC flavors. It searches the environment variables (CC, CXX, etc.) or simply tries to call the compiler. In addition it will detect any prefixes (when cross-compiling) and tries to add it to all binutils of the GNU compiler toolchain (ar
, ranlib
, strip
, ld
, nm
, objdump
, and objcopy
).
If notepad is already started, you should write:
// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);
//...
Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
}
GetProcessesByName
returns an array of processes, so you should get the first one (or find the one you want).
If you want to start notepad
and send the key, you should write:
Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
The only situation in which the code may not work is when notepad
is started as Administrator and your application is not.
By using Interceptor you can catch error. Below is code:
@Injectable()
export class ResponseInterceptor implements HttpInterceptor {
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
//Get Auth Token from Service which we want to pass thr service call
const authToken: any = `Bearer ${sessionStorage.getItem('jwtToken')}`
// Clone the service request and alter original headers with auth token.
const authReq = req.clone({
headers: req.headers.set('Content-Type', 'application/json').set('Authorization', authToken)
});
const authReq = req.clone({ setHeaders: { 'Authorization': authToken, 'Content-Type': 'application/json'} });
// Send cloned request with header to the next handler.
return next.handle(authReq).do((event: HttpEvent<any>) => {
if (event instanceof HttpResponse) {
console.log("Service Response thr Interceptor");
}
}, (err: any) => {
if (err instanceof HttpErrorResponse) {
console.log("err.status", err);
if (err.status === 401 || err.status === 403) {
location.href = '/login';
console.log("Unauthorized Request - In case of Auth Token Expired");
}
}
});
}
}
You can prefer this blog..given simple example for it.
In order to stay on the same page on submit you can leave action empty (action=""
) into the form tag, or leave it out altogether.
For the message, create a variable ($message = "Success! You entered: ".$input;"
) and then echo the variable at the place in the page where you want the message to appear with <?php echo $message; ?>
.
Like this:
<?php
$message = "";
if(isset($_POST['SubmitButton'])){ //check if form was submitted
$input = $_POST['inputText']; //get input text
$message = "Success! You entered: ".$input;
}
?>
<html>
<body>
<form action="" method="post">
<?php echo $message; ?>
<input type="text" name="inputText"/>
<input type="submit" name="SubmitButton"/>
</form>
</body>
</html>

<input type="button" id="002" onclick=gO("getPosition") value="Position"/>

<div id="101">
</div>
</h3>
<script type="text/javascript">
var elem=document.getElementById("101");
function gO(callback){
script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'http://localhost/test/server.php?callback='+callback;
elem.appendChild(script);
elem.removeChild(script);
}
function getCompany(data){
var message="The company you work for is "+data.company +"<img src='"+data.image+"'/ >";
elem.innerHTML=message;
}
function getPosition(data){
var message="The position you are offered is "+data.position;
elem.innerHTML=message;
}
</script>

<?php
$callback=$_GET["callback"];

From Java 9, you can use the stream provided by Matcher.results()
long matches = matcher.results().count();
As long as you override equals()
on each key and value contained in the map, then m1.equals(m2)
should be reliable to check for maps equality.
The same result can be obtained also by comparing toString()
of each map as you suggested, but using equals()
is a more intuitive approach.
May not be your specific situation, but if you store arrays in the map, may be a little tricky, because they must be compared value by value, or using Arrays.equals()
. More details about this see here.
Part 1 of your question:
var allChecked = true;
$("input.abc").each(function(index, element){
if(!element.checked){
allChecked = false;
return false;
}
});
EDIT:
The answer (http://stackoverflow.com/questions/5541387/check-if-all-checkboxes-are-selected/5541480#5541480) above is probably better.
The video quality depends upon the Connection speed using API
alternatively for other than API means without YouTube app you can follow this link
$location won't help you with external URLs, use the $window service instead:
$window.location.href = 'http://www.google.com';
Note that you could use the window object, but it is bad practice since $window is easily mockable whereas window is not.
Moreover to convert whatever you want, you can use QVariant
.
For an int
to a QString
you get:
QVariant(3).toString();
A float
to a string
or a string
to a float
:
QVariant(3.2).toString();
QVariant("5.2").toFloat();
I know this is not the OPs issue, but I had this happen on a project. The solution had multiple MVC projects and the wrong project was set as startup.
I had also set the configuration of the project(s) to just start process/debugger and not open a new browser window.
So on the surface it looks as if the debugger is starting up, but it does so for the wrong process. So check that and keep in mind that you can attach to multiple processes also.
Silly mistake that left me scratching my head for about 30 minutes.
Give this a try
<style type="text/css">
form {width:400px;}
#text1 {float:right;}
#text2 {float:left;}
</style>
then
<form id="form1" name="form1" method="post" action="">
<label id="text1">Company Name<br />
<input type="text" name="textfield2" id="textfield2" />
</label>
<label id="text2">Contact Name<br />
<input type="text" name="textfield" id="textfield" />
</label>
</form>

Works for me in the latest versions of Firefox, Safari, Chrome, Opera. Not 100% sure about IE though as im on a Mac, but I cant see why it wouldn't :)
Use the following instead:
boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );
This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.
Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.
Go's net/http package has many functions that deal with headers. Among them are Add, Del, Get and Set methods. The way to use Set is:
func yourHandler(w http.ResponseWriter, r *http.Request) {
w.Header().Set("header_name", "header_value")
}
You used the egg files install procedure.
This procedure supports installing over git
, git+http
, git+https
, git+ssh
, git+git
and git+file
. Some of these are mentioned.
It's good you can use branches, tags, or hashes to install.
@Steve_K noted it can be slow to install with "git+" and proposed installing via zip file:
pip install https://github.com/user/repository/archive/branch.zip
Alternatively, I suggest you may install using the .whl
file if this exists.
pip install https://github.com/user/repository/archive/branch.whl
It's pretty new format, newer than egg files. It requires wheel and setuptools>=0.8 packages. You can find more in here.
The margins vary depending on the printer. In Windows GDI, you call the following functions to get the built-in margins, the "no-print zone":
GetDeviceCaps(hdc, PHYSICALWIDTH);
GetDeviceCaps(hdc, PHYSICALHEIGHT);
GetDeviceCaps(hdc, PHYSICALOFFSETX);
GetDeviceCaps(hdc, PHYSICALOFFSETY);
Printing right to the edge is called a "bleed" in the printing industry. The only laser printer I ever knew to print right to the edge was the Xerox 9700: 120 ppm, $500K in 1980.

Unfortunately, there's no way to do that with CSS.
It's not very difficult with JavaScript though:
// JavaScript code:
document.getElementsByClassName("active")[0].parentNode;
// jQuery code:
$('.active').parent().get(0); // This would be the <a>'s parent <li>.
Your program should not write temporary files (or anything else for that matter) to the program directory. Any program should use %TEMP% for temporary files and %APPDATA% for user specific application data. This has been true since Windows 2000/XP so you should change your aplication.
The problem is not Windows 7.
You can ask for appdata folder path:
string dir = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
or for TEMP path
string dir = Path.GetTempPath()
I was facing the same issue A generic error occurred in GDI+ on saving while working on MVC app, I was getting this error because I was writing wrong path to save image, I corrected saving path and it worked fine for me.
img1.Save(Server.MapPath("/Upload/test.png", System.Drawing.Imaging.ImageFormat.Png);

It is a special for when a Python file is called from the command line. This is typically used to call a "main()" function or execute other appropriate startup code, like commandline arguments handling for instance.
It could be written in several ways. Another is:
def some_function_for_instance_main():
dosomething()
__name__ == '__main__' and some_function_for_instance_main()
I am not saying you should use this in production code, but it serves to illustrate that there is nothing "magical" about if __name__ == '__main__'
. It is a good convention for invoking a main function in Python files.
import java.lang.String;
This is an unnecessary import. java.lang classes are always implicitly imported. This means that you do not have to import them manually (explicitly).
You can even set a separate right margin for HTML. Under the specified path:

This is very useful because generally HTML and JS may be usually long in one line than Python. :)

I think the question asker is (was) thinking that git bash is a command like git init or git checkout. Git bash is not a command, it is an interface. I will also assume the asker is not a linux user because bash is very popular the unix/linux world. The name "bash" is an acronym for "Bourne Again SHell". Bash is a text-only command interface that has features which allow automated scripts to be run. A good analogy would be to compare bash to the new PowerShell interface in Windows7/8. A poor analogy (but one likely to be more readily understood by more people) is the combination of the command prompt and .BAT (batch) command files from the days of DOS and early versions of Windows.

Since I cannot add this as a comment
, I will leave it here for anyone who finds backticks to be easier to read. Its basically @Reigel answer but with backticks
var numbers = [1, 2, 3, 4, 5];

for (var i=0;i<numbers.length;i++){
option += `<option value=${numbers[i]}>${numbers[i]}</option>`;
}

If the return
in the try
block is reached, it transfers control to the finally
block, and the function eventually returns normally (not a throw).
If an exception occurs, but then the code reaches a return
from the catch
block, control is transferred to the finally
block and the function eventually returns normally (not a throw).
In your example, you have a return
in the finally
, and so regardless of what happens, the function will return 34
, because finally
has the final (if you will) word.
Although not covered in your example, this would be true even if you didn't have the catch
and if an exception were thrown in the try
block and not caught. By doing a return
from the finally
block, you suppress the exception entirely. Consider:
public class FinallyReturn {
public static final void main(String[] args) {
System.out.println(foo(args));
}
private static int foo(String[] args) {
try {
int n = Integer.parseInt(args[0]);
return n;
}
finally {
return 42;
}
}
}
If you run that without supplying any arguments:
$ java FinallyReturn
...the code in foo
throws an ArrayIndexOutOfBoundsException
. But because the finally
block does a return
, that exception gets suppressed.
This is one reason why it's best to avoid using return
in finally
.
It don't create normally; you need to add it by yourself.

and also add an inherit attribute to the Global.asax file.
Your Global.asax will look like this: -
<%@ Application Language="C#" Inherits="Global" %>
Your Global.cs in App_Code
will look like this: -
public class Global : System.Web.HttpApplication
{
public Global()
{
//
// TODO: Add constructor logic here
//
}
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
}
/// Many other events like begin request...e.t.c, e.t.c
}
Not exactly what you want, but a related useful tool is getattr()
, to use method's name as a parameter.
class MyClass:
def __init__(self):
pass
def MyMethod(self):
print("Method ran")
# Create an object
object = MyClass()
# Get all the methods of a class
method_list = [func for func in dir(MyClass) if callable(getattr(MyClass, func))]
# You can use any of the methods in method_list
# "MyMethod" is the one we want to use right now
# This is the same as running "object.MyMethod()"
getattr(object,'MyMethod')()
You can use Array.every
if supported:
var equals = array.every(function(value, index, array){
return value === array[0];
});
Alternatives approach of a loop could be something like sort
var temp = array.slice(0).sort();
var equals = temp[0] === temp[temp.length - 1];
Or, if the items are like the question, something dirty like:
var equals = array.join('').split(array[0]).join('').length === 0;
Also works.
For completeness, the boost way would be to use boost::format
cout << boost::format("%s %s > %s") % a % b % c;
Take your pick. The boost solution has the advantage of type safety with the sprintf
format (for those who find the <<
syntax a bit clunky).
whatever yyy is undefined or null, it will return true
if (typeof yyy == 'undefined' || !yyy) {
console.log('yes');
} else {
console.log('no');
}
yes
if (!(typeof yyy == 'undefined' || !yyy)) {
console.log('yes');
} else {
console.log('no');
}
no
You should use doGet()
when you want to intercept on HTTP GET requests. You should use doPost()
when you want to intercept on HTTP POST requests. That's all. Do not port the one to the other or vice versa (such as in Netbeans' unfortunate auto-generated processRequest()
method). This makes no utter sense.
Usually, HTTP GET requests are idempotent. I.e. you get exactly the same result everytime you execute the request (leaving authorization/authentication and the time-sensitive nature of the page —search results, last news, etc— outside consideration). We can talk about a bookmarkable request. Clicking a link, clicking a bookmark, entering raw URL in browser address bar, etcetera will all fire a HTTP GET request. If a Servlet is listening on the URL in question, then its doGet()
method will be called. It's usually used to preprocess a request. I.e. doing some business stuff before presenting the HTML output from a JSP, such as gathering data for display in a table.
@WebServlet("/products")
public class ProductsServlet extends HttpServlet {
@EJB
private ProductService productService;
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
List<Product> products = productService.list();
request.setAttribute("products", products); // Will be available as ${products} in JSP
request.getRequestDispatcher("/WEB-INF/products.jsp").forward(request, response);
}
}
Note that the JSP file is explicitly placed in /WEB-INF
folder in order to prevent endusers being able to access it directly without invoking the preprocessing servlet (and thus end up getting confused by seeing an empty table).
<table>
<c:forEach items="${products}" var="product">
<tr>
<td>${product.name}</td>
<td><a href="product?id=${product.id}">detail</a></td>
</tr>
</c:forEach>
</table>
Also view/edit detail links as shown in last column above are usually idempotent.
@WebServlet("/product")
public class ProductServlet extends HttpServlet {
@EJB
private ProductService productService;
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Product product = productService.find(request.getParameter("id"));
request.setAttribute("product", product); // Will be available as ${product} in JSP
request.getRequestDispatcher("/WEB-INF/product.jsp").forward(request, response);
}
}
<dl>
<dt>ID</dt>
<dd>${product.id}</dd>
<dt>Name</dt>
<dd>${product.name}</dd>
<dt>Description</dt>
<dd>${product.description}</dd>
<dt>Price</dt>
<dd>${product.price}</dd>
<dt>Image</dt>
<dd><img src="productImage?id=${product.id}" /></dd>
</dl>
HTTP POST requests are not idempotent. If the enduser has submitted a POST form on an URL beforehand, which hasn't performed a redirect, then the URL is not necessarily bookmarkable. The submitted form data is not reflected in the URL. Copypasting the URL into a new browser window/tab may not necessarily yield exactly the same result as after the form submit. Such an URL is then not bookmarkable. If a Servlet is listening on the URL in question, then its doPost()
will be called. It's usually used to postprocess a request. I.e. gathering data from a submitted HTML form and doing some business stuff with it (conversion, validation, saving in DB, etcetera). Finally usually the result is presented as HTML from the forwarded JSP page.
<form action="login" method="post">
<input type="text" name="username">
<input type="password" name="password">
<input type="submit" value="login">
<span class="error">${error}</span>
</form>
...which can be used in combination with this piece of Servlet:
@WebServlet("/login")
public class LoginServlet extends HttpServlet {
@EJB
private UserService userService;
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("username");
String password = request.getParameter("password");
User user = userService.find(username, password);
if (user != null) {
request.getSession().setAttribute("user", user);
response.sendRedirect("home");
}
else {
request.setAttribute("error", "Unknown user, please try again");
request.getRequestDispatcher("/login.jsp").forward(request, response);
}
}
}
You see, if the User
is found in DB (i.e. username and password are valid), then the User
will be put in session scope (i.e. "logged in") and the servlet will redirect to some main page (this example goes to http://example.com/contextname/home
), else it will set an error message and forward the request back to the same JSP page so that the message get displayed by ${error}
.
You can if necessary also "hide" the login.jsp
in /WEB-INF/login.jsp
so that the users can only access it by the servlet. This keeps the URL clean http://example.com/contextname/login
. All you need to do is to add a doGet()
to the servlet like this:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.getRequestDispatcher("/WEB-INF/login.jsp").forward(request, response);
}
(and update the same line in doPost()
accordingly)
That said, I am not sure if it is just playing around and shooting in the dark, but the code which you posted doesn't look good (such as using compareTo()
instead of equals()
and digging in the parameternames instead of just using getParameter()
and the id
and password
seems to be declared as servlet instance variables — which is NOT threadsafe). So I would strongly recommend to learn a bit more about basic Java SE API using the Oracle tutorials (check the chapter "Trails Covering the Basics") and how to use JSP/Servlets the right way using those tutorials.
Update: as per the update of your question (which is pretty major, you should not remove parts of your original question, this would make the answers worthless .. rather add the information in a new block) , it turns out that you're unnecessarily setting form's encoding type to multipart/form-data
. This will send the request parameters in a different composition than the (default) application/x-www-form-urlencoded
which sends the request parameters as a query string (e.g. name1=value1&name2=value2&name3=value3
). You only need multipart/form-data
whenever you have a <input type="file">
element in the form to upload files which may be non-character data (binary data). This is not the case in your case, so just remove it and it will work as expected. If you ever need to upload files, then you'll have to set the encoding type so and parse the request body yourself. Usually you use the Apache Commons FileUpload there for, but if you're already on fresh new Servlet 3.0 API, then you can just use builtin facilities starting with HttpServletRequest#getPart()
. See also this answer for a concrete example: How to upload files to server using JSP/Servlet?
run psql -E
and then \d student_details
Angular doesn't know about that change. For this you should call $scope.$digest()
or make the change inside of $scope.$apply()
:
$scope.$apply(function() {
// every changes goes here
$('#selectedDueDate').val(dateText);
});
See this to better understand dirty-checking
UPDATE: Here is an example
You are returning char, and not char*, which is the pointer to the first character of an array.
If you want to return a new character array instead of doing in-place modification, you can ask for an already allocated pointer (char*) as parameter or an uninitialized pointer. In this last case you must allocate the proper number of characters for new string and remember that in C parameters as passed by value ALWAYS, so you must use char** as parameter in the case of array allocated internally by function. Of course, the caller must free that pointer later.
The difference in whether you have to instantiate your @InjectMocks
annotated field is in the version of Mockito, not in whether you use the MockitoJunitRunner or MockitoAnnotations.initMocks
. In 1.9, which will also handle some constructor injection of your @Mock
fields, it will do the instantiation for you. In earlier versions, you have to instantiate it yourself.
This is how I do unit testing of my Spring beans. There is no problem. People run into confusion when they want to use Spring configuration files to actually do the injection of the mocks, which is crossing up the point of unit tests and integration tests.
And of course the unit under test is an Impl. You need to test a real concrete thing, right? Even if you declared it as an interface you would have to instantiate the real thing to test it. Now, you could get into spies, which are stub/mock wrappers around real objects, but that should be for corner cases.
The optional key
parameter to sort
/sorted
is a function. The function is called for each item and the return values determine the ordering of the sort
>>> lst = [['John', 2], ['Jim', 9], ['Jason', 1]]
>>> def my_key_func(item):
... print("The key for {} is {}".format(item, item[1]))
... return item[1]
...
>>> sorted(lst, key=my_key_func)
The key for ['John', 2] is 2
The key for ['Jim', 9] is 9
The key for ['Jason', 1] is 1
[['Jason', 1], ['John', 2], ['Jim', 9]]
taking the print
out of the function leaves
>>> def my_key_func(item):
... return item[1]
This function is simple enough to write "inline" as a lambda function
>>> sorted(lst, key=lambda item: item[1])
[['Jason', 1], ['John', 2], ['Jim', 9]]
check all the variables names in both of the combined files. Name of variables of both files to be combines should be exact same or else it will produce the above mentioned errors. I was facing the same problem as well, and after making all names same in both the file, rbind works accurately.
Thanks
On server-side it will be not as accurate as with JavaScript. Meanwhile, sometimes it is required to solve such task. Just to share the possible solution in this case I write this answer.
If you need to determine user's time zone it could be done via Geo-IP services. Some of them providing timezone. For example, this one (http://smart-ip.net/geoip-api) could help:
<?php
$ip = $_SERVER['REMOTE_ADDR']; // means we got user's IP address
$json = file_get_contents( 'http://smart-ip.net/geoip-json/' . $ip); // this one service we gonna use to obtain timezone by IP
// maybe it's good to add some checks (if/else you've got an answer and if json could be decoded, etc.)
$ipData = json_decode( $json, true);
if ($ipData['timezone']) {
$tz = new DateTimeZone( $ipData['timezone']);
$now = new DateTime( 'now', $tz); // DateTime object corellated to user's timezone
} else {
// we can't determine a timezone - do something else...
}
I have implemented a wrapper if anyone would like to specify variable types.
import functools
def type_check(func):
@functools.wraps(func)
def check(*args, **kwargs):
for i in range(len(args)):
v = args[i]
v_name = list(func.__annotations__.keys())[i]
v_type = list(func.__annotations__.values())[i]
error_msg = 'Variable `' + str(v_name) + '` should be type ('
error_msg += str(v_type) + ') but instead is type (' + str(type(v)) + ')'
if not isinstance(v, v_type):
raise TypeError(error_msg)
result = func(*args, **kwargs)
v = result
v_name = 'return'
v_type = func.__annotations__['return']
error_msg = 'Variable `' + str(v_name) + '` should be type ('
error_msg += str(v_type) + ') but instead is type (' + str(type(v)) + ')'
if not isinstance(v, v_type):
raise TypeError(error_msg)
return result
return check
Use it as:
@type_check
def test(name : str) -> float:
return 3.0
@type_check
def test2(name : str) -> str:
return 3.0
>> test('asd')
>> 3.0
>> test(42)
>> TypeError: Variable `name` should be type (<class 'str'>) but instead is type (<class 'int'>)
>> test2('asd')
>> TypeError: Variable `return` should be type (<class 'str'>) but instead is type (<class 'float'>)
The code above does not work if any of the arguments' (or return's) type is not declared. The following edit can help, on the other hand, it only works for kwargs and does not check args.
def type_check(func):
@functools.wraps(func)
def check(*args, **kwargs):

error_msg += str(v_type) + ') but instead is type (' + str(type(v)) + ') '
if not isinstance(v, v_type):
raise TypeError(error_msg)
result = func(*args, **kwargs)

Using arrow keys to go to the start of the command and hitting enter copies it as the current command.
Then just hit enter to run it again.
None of the current answers worked for me because my data was in this format from the unix side:
2016-02-02 19:21:42 UTC
I needed to convert this to Epoch to allow referencing other data which had epoch timestamps.
Create a new column for the date part and parse with this formula
=DATEVALUE(MID(A2,6,2) & "/" & MID(A2,9,2) & "/" & MID(A2,1,4))
As other Grendler has stated here already, create another column
=(B2-DATE(1970,1,1))*86400
Create another column with just the time added together to get total seconds:
=(VALUE(MID(A2,12,2))*60*60+VALUE(MID(A2,15,2))*60+VALUE(MID(A2,18,2)))
Create a last column that just adds the last two columns together:
=C2+D2

Nicest way to implement automatically selecting the text on receiving focus is to create a subclass of TextBox in your project with the following override:
Protected Overrides Sub OnGotFocus(ByVal e As System.EventArgs)
SelectionStart = 0
SelectionLength = Text.Length
MyBase.OnGotFocus(e)
End Sub
Then use this custom TextBox in place of the WinForms standard TextBox on all your Forms.
I wonder about is there any change in my master branch...
git checkout master
git status
git branch -a

git diff origin/master
For collection types I would return an Empty Collection, for all other types I prefer using the NullObject patterns for returning an object that implements the same interface as that of the returning type. for details about the pattern check out link text
Using the NullObject pattern this would be :-
public UserEntity GetUserById(Guid userId)
{ //Imagine some code here to access database.....
//Check if data was returned and return a null if none found
if (!DataExists)
return new NullUserEntity(); //Should I be doing this here instead? return new UserEntity();
else
return existingUserEntity;
}
class NullUserEntity: IUserEntity { public string getFirstName(){ return ""; } ...}
you can't use VALUES
clause when inserting data using another SELECT
query. see INSERT SYNTAX
INSERT INTO user
(
id, name, username, email, opted_in
)
(
SELECT id, name, username, email, opted_in
FROM user
LEFT JOIN user_permission AS userPerm
ON user.id = userPerm.user_id
);
reload()
is supposed to accept an argument which tells it to do a hard reload, ie, ignoring the cache:
location.reload(true);
I can't vouch for its reliability, you may want to investigate this further.
this example may be useful:
<html>_x000D_
<head>_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>_x000D_
</head>_x000D_
<body>_x000D_
<input id="test" type="text" />_x000D_
<button onclick="testF()" >click</button>_x000D_
_x000D_
_x000D_
<script>_x000D_
function testF(){_x000D_
_x000D_
alert($('#test').attr('value'));_x000D_
alert( $('#test').prop('value'));_x000D_
alert($('#test').val());_x000D_
}_x000D_
</script>_x000D_
</body>_x000D_
</html>
_x000D_
in above example, everything works perfectly. but if you change the version of jquery to 1.9.1 or newer in script tag you will see "undefined" in the first alert. attr('value') doesn't work with jquery version 1.9.1 or newer.

You can access directly the request array with $request['key'] = 'value'
;
Try running this, where x is any number
int_sign = bool(x > 0) - bool(x < 0)
The coercion to bool() handles the possibility that the comparison operator doesn't return a boolean.
If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:
The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.
This works for me:
scrollview.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
scrollview.post(new Runnable() {
public void run() {
scrollview.fullScroll(View.FOCUS_DOWN);
}
});
}
});
__func__
is documented in the C++0x standard at section 8.4.1. In this case it's a predefined function local variable of the form:
static const char __func__[] = "function-name ";
where "function name" is implementation specfic. This means that whenever you declare a function, the compiler will add this variable implicitly to your function. The same is true of __FUNCTION__
and __PRETTY_FUNCTION__
. Despite their uppercasing, they aren't macros. Although __func__
is an addition to C++0x
g++ -std=c++98 ....
will still compile code using __func__
.
__PRETTY_FUNCTION__
and __FUNCTION__
are documented here http://gcc.gnu.org/onlinedocs/gcc-4.5.1/gcc/Function-Names.html#Function-Names. __FUNCTION__
is just another name for __func__
. __PRETTY_FUNCTION__
is the same as __func__
in C but in C++ it contains the type signature as well.

What about this for a catch all...
if (string.IsNullOrEmpty(x.Trim())
{
}
This will trim all the spaces if they are there avoiding the performance penalty of IsWhiteSpace, which will enable the string to meet the "empty" condition if its not null.
I also think this is clearer and its generally good practise to trim strings anyway especially if you are putting them into a database or something.
You can also use something like
<c:if test="${ testObject.testPropert == "testValue" }">...</c:if>
You can use the Sum
function, but you'll have to convert the strings to integers, like so:
int total = monValues.Sum(x => Convert.ToInt32(x));
In this situation implode($array,','); will works, becasue you want the values only. In PHP 5.6 working for me.
If you want to implode the keys and the values in one like :
blogTags_id: 1
tag_name: google
$toImplode=array();
foreach($array as $key => $value) {
$toImplode[]= "$key: $value".'<br>';
}
$imploded=implode('',$toImplode);
Sorry, I understand wrong, becasue the title "Implode data from a multi-dimensional array". Well, my answer still answer it somehow, may help someone, so will not delete it.
jsPDF is able to use plugins. In order to enable it to print HTML, you have to include certain plugins and therefore have to do the following:
If you want to ignore certain elements, you have to mark them with an ID, which you can then ignore in a special element handler of jsPDF. Therefore your HTML should look like this:
<!DOCTYPE html>
<html>
<body>
<p id="ignorePDF">don't print this to pdf</p>
<div>
<p><font size="3" color="red">print this to pdf</font></p>
</div>
</body>
</html>
Then you use the following JavaScript code to open the created PDF in a PopUp:
var doc = new jsPDF();
var elementHandler = {
'#ignorePDF': function (element, renderer) {
return true;
}
};
var source = window.document.getElementsByTagName("body")[0];
doc.fromHTML(
source,
15,
15,
{
'width': 180,'elementHandlers': elementHandler
});
doc.output("dataurlnewwindow");
For me this created a nice and tidy PDF that only included the line 'print this to pdf'.
Please note that the special element handlers only deal with IDs in the current version, which is also stated in a GitHub Issue. It states:
Because the matching is done against every element in the node tree, my desire was to make it as fast as possible. In that case, it meant "Only element IDs are matched" The element IDs are still done in jQuery style "#id", but it does not mean that all jQuery selectors are supported.
Therefore replacing '#ignorePDF' with class selectors like '.ignorePDF' did not work for me. Instead you will have to add the same handler for each and every element, which you want to ignore like:
var elementHandler = {
'#ignoreElement': function (element, renderer) {
return true;
},
'#anotherIdToBeIgnored': function (element, renderer) {
return true;
}
};
From the examples it is also stated that it is possible to select tags like 'a' or 'li'. That might be a little bit to unrestrictive for the most usecases though:
We support special element handlers. Register them with jQuery-style ID selector for either ID or node name. ("#iAmID", "div", "span" etc.) There is no support for any other type of selectors (class, of compound) at this time.
One very important thing to add is that you lose all your style information (CSS). Luckily jsPDF is able to nicely format h1, h2, h3 etc., which was enough for my purposes. Additionally it will only print text within text nodes, which means that it will not print the values of textareas and the like. Example:
<body>
<ul>
<!-- This is printed as the element contains a textnode -->
<li>Print me!</li>

Perhaps you can use something like Gaussian Mixture Models. Here's a Python package for doing GMMs (just did a Google search) http://www.ar.media.kyoto-u.ac.jp/members/david/softwares/em/
If you want a real timer you need to use the date object.
Calculate the difference.
Format your string.
window.onload=function(){
var start=Date.now(),r=document.getElementById('r');
(function f(){
var diff=Date.now()-start,ns=(((3e5-diff)/1e3)>>0),m=(ns/60)>>0,s=ns-m*60;
r.textContent="Registration closes in "+m+':'+((''+s).length>1?'':'0')+s;
if(diff>3e5){
start=Date.now()
}
setTimeout(f,1e3);
})();
}
Example
not so precise timer
var time=5*60,r=document.getElementById('r'),tmp=time;
setInterval(function(){
var c=tmp--,m=(c/60)>>0,s=(c-m*60)+'';
r.textContent='Registration closes in '+m+':'+(s.length>1?'':'0')+s
tmp!=0||(tmp=time);
},1000);
If you want to use "true" (floating point) division by default, there is a command line flag:
python -Q new foo.py
There are some drawbacks (from the PEP):
It has been argued that a command line option to change the default is evil. It can certainly be dangerous in the wrong hands: for example, it would be impossible to combine a 3rd party library package that requires -Qnew with another one that requires -Qold.
You can learn more about the other flags values that change / warn-about the behavior of division by looking at the python man page.
For full details on division changes read: PEP 238 -- Changing the Division Operator
This error also occurs if you forgot adding the private key to ssh-agent
. Do this with:
ssh-add ~/.ssh/id_rsa
HTTP does not place a predefined limit on the length of each header field or on the length of the header section as a whole, as described in Section 2.5. Various ad hoc limitations on individual header field length are found in practice, often depending on the specific field semantics.
HTTP Header values are restricted by server implementations. Http specification doesn't restrict header size.
A server that receives a request header field, or set of fields, larger than it wishes to process MUST respond with an appropriate 4xx (Client Error) status code. Ignoring such header fields would increase the server's vulnerability to request smuggling attacks (Section 9.5).
Most servers will return 413 Entity Too Large
or appropriate 4xx error when this happens.
A client MAY discard or truncate received header fields that are larger than the client wishes to process if the field semantics are such that the dropped value(s) can be safely ignored without changing the message framing or response semantics.
Uncapped HTTP header size keeps the server exposed to attacks and can bring down its capacity to serve organic traffic.
If your folder already have
package.json
Then,
Copy the path of package.json
Open terminal
Write:
cd your_path_to_package.json
Press ENTER
Then Write:
npm install
This worked for me
Thanks to all example providers, some worked for some not. Below is another simple example format that worked for me.
echo "Sample body" | mail -s "Test email" [email protected] [email protected]
I got same issue. I was getting the System.Data.Entity.Infrastructure; error which is only part of v5.0 or later. Just right click the Reference and select "Manage NuGet Package" . In the Installed Package option , uninstall the Entity FrameWork which is already installed and Install the 5.0 version. It solve the problem. I was trying manually get the System.Data.Entity reference , which was not success.
You can also use bellow code for pass data using ajax.
var dataString = "album" + title;
$.ajax({
type: 'POST',
url: 'test.php',
data: dataString,
success: function(response) {
content.html(response);
}
});
The suggested solutions are incompatible with Seaborn 0.8.1
giving the following errors because the Seaborn interface has changed:
AttributeError: 'AxesSubplot' object has no attribute 'fig'
When trying to access the figure
AttributeError: 'AxesSubplot' object has no attribute 'savefig'
when trying to use the savefig directly as a function
The following calls allow you to access the figure (Seaborn 0.8.1 compatible):
swarm_plot = sns.swarmplot(...)
fig = swarm_plot.get_figure()
fig.savefig(...)
as seen previously in this answer.
UPDATE: I have recently used PairGrid object from seaborn to generate a plot similar to the one in this example. In this case, since GridPlot is not a plot object like, for example, sns.swarmplot, it has no get_figure() function. It is possible to directly access the matplotlib figure by
fig = myGridPlotObject.fig
Like previously suggested in other posts in this thread.
You can easily draw simple svg

You can set your hash directly to URL too.
window.location.hash = "YourHash";
The result : http://url#YourHash
Note: cuongle's helfpul answer has all the ingredients, but the solution can be streamlined (no need for .ItemArray
) and can be reframed to better match the question as asked.
To create an (isolated) clone of a given System.Data.DataRow
instance, you can do the following:
// Assume that variable `table` contains the source data table.
// Create an auxiliary, empty, column-structure-only clone of the source data table.
var tableAux = table.Clone();
// Note: .Copy(), by contrast, would clone the data rows also.
// Select the data row to clone, e.g. the 2nd one:
var row = table.Rows[1];
// Import the data row of interest into the aux. table.
// This creates a *shallow clone* of it.
// Note: If you'll be *reusing* the aux. table for single-row cloning later, call
// tableAux.Clear() first.
tableAux.ImportRow(row);
// Extract the cloned row from the aux. table:
var rowClone = tableAux.Rows[0];
Note: Shallow cloning is performed, which works as-is with column values that are value type instances, but more work would be needed to also create independent copies of column values containing reference type instances (and creating such independent copies isn't always possible).
You are not selecting multiple indexes with PriceList[0][1][2][3][4][5][6] , instead each [] is going into a sub index.
Try this
PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))
PriceList[0:7]=[PizzaChange]*7
PriceList[7:11]=[PizzaChange+3]*4
I resolved error copying the files class.phpmailer.php , class.smtp.php to the folder where the file is PHPMailerAutoload.php, of course there should be the file that we will use to send the email.
in your selector, you should also specify that you want the checked radiobutton:
$(function(){
$("#submit").click(function(){
alert($('input[name=q12_3]:checked').val());
});
});
If you can create a string xml you can easily transform it to the xml document object e.g. -
String xmlString = "<?xml version=\"1.0\" encoding=\"utf-8\"?><a><b></b><c></c></a>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
try {
builder = factory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(xmlString)));
} catch (Exception e) {
e.printStackTrace();
}
You can use the document object and xml parsing libraries or xpath to get back the ip address.
When you use laravel modules, you may add the name's module:
@include('cimple::shared.posts_list')
To give an in-action memory usage aspect, I did an experiment with Strong, Soft, Weak & Phantom references under heavy load with heavy objects by retaining them till end of program. Then monitored heap usage & GC behavior. These metrics may vary case by case basis but surely gives high level understanding. Below are findings.
Heap & GC Behavior under heavy load
You can get more in depth graphs, stats, observations for this experiment here.
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]

to avoid overwriting the file if two users send a request at the same timeTo add a file/folder to the project, a good way is:
First of all add your files to /path/to/your/project/my/added/files, and then run following commands:
svn cleanup /path/to/your/project
svn add --force /path/to/your/project/*
svn cleanup /path/to/your/project
svn commit /path/to/your/project -m 'Adding a file'
I used cleanup to prevent any segmentation fault (core dumped), and now the SVN project is updated.
You have a class on your CSS that is overwriting your width and height, the class reads as such:
.postItem img {
height: auto;
width: 450px;
}
Remove that and your width/height properties on the img
tag should work.
Believe this occurs because you have a child repository "submodule" that has changes which have not been staged and committed.
Had a similar problem, where my IDE kept reporting uncommitted changes, and running the stage (git add .
) and commit (git commit -m "message"
) commands had no effect. Thinking about this in hindsight, it's probably because the child repository had the changes that needed to be staged and committed, not the parent repository.
cd
into the submodule (has a hidden folder named .git
) and execute the commands to stage (git add .
) and commit (git commit -m "Update child repo"
)cd ..
back to the parent repo, and execute the commands to stage (git add .
) and commit (git commit -m "Update parent repo"
)sudo rm -Rf .git
== DO NOT USE THIS COMMAND == it permanently deletes submodule repository history (the purpose of GIT)git add -A

I was trying to find the meaning of GRANT USAGE on *.* TO
and found here. I can clarify that GRANT USAGE on *.* TO user IDENTIFIED BY PASSWORD password
will be granted when you create the user with the following command (CREATE
):
CREATE USER 'user'@'localhost' IDENTIFIED BY 'password';
When you grant privilege with GRANT
, new privilege s will be added on top of it.
It's a good practice if you need them. It's also a good practice is they make sense, so future coders can understand what you're doing.
But generally, no it's not a good practice to attach 10 class names to an object because most likely whatever you're using them for, you could accomplish the same thing with far fewer classes. Probably just 1 or 2.
To qualify that statement, javascript plugins and scripts may append far more classnames to do whatever it is they're going to do. Modernizr for example appends anywhere from 5 - 25 classes to your body tag, and there's a very good reason for it. jQuery UI appends lots of classnames when you use one of the widgets in that library.
To answer my own question, the trick is to turn auto scaling off...
p.axis([0.0,600.0, 10000.0,20000.0])
ax = p.gca()
ax.set_autoscale_on(False)
If you are using pdo, it will look like
$sql = "UPDATE users SET firstname = :firstname, lastname = :lastname WHERE id= :id";
$query = $this->pdo->prepare($sql);
$result = $query->execute(array(':firstname' => $firstname, ':lastname' => $lastname, ':id' => $id));
Perhaps the whole column full of random numbers is not the best way to do it, but it seems like probably the most practical as @mariusnn mentioned.
On that note, this stomped me for a while with Office 2010, and while generally answers like the one in lifehacker work,I just wanted to share an extra step required for the numbers to be unique:
=rand()
in the first cell of the new column - this will generate a random number between 0 and 1Fill the column with that formula. The easiest way to do this may be to:
Now you should have a column of identical numbers, even though they are all generated randomly.
The trick here is to recalculate them! Go to the Formulas tab and then click on Calculate Now (or press F9).
Now all the numbers in the column will be actually generated randomly.
Go to the Home tab and click on Sort & Filter. Choose whichever order you want (Smallest to Largest or Largest to Smallest) - whichever one will give you a random order with respect to the original order. Then click OK when the Sort Warning prompts you to Expand the selection.
Your list should be randomized now! You can get rid of the column of random numbers if you want.
ListenForClients

This can be helpful:
<input type="text" name="username" value="admin" >
<style type="text/css">
input[name=username] {

and if want to disable from tab index you can use it this way:
<input type="text" name="username" value="admin" tabindex="-1" >
<style type="text/css">
input[name=username] {
pointer-events: none;
}

This solution is non-recursive. Note that the order of the elements will be somewhat mixed.

$return = array();
while(count($array)) {
$value = array_shift($array);

$return[] = $value;
}
return $return;
}
Here's a fix for LoaderException errors you're likely to find if one of the types sublasses a type in another assembly:
// Setup event handler to resolve assemblies
AppDomain.CurrentDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(CurrentDomain_ReflectionOnlyAssemblyResolve);
Assembly a = System.Reflection.Assembly.ReflectionOnlyLoadFrom(filename);
a.GetTypes();
// process types here
// method later in the class:
static Assembly CurrentDomain_ReflectionOnlyAssemblyResolve(object sender, ResolveEventArgs args)
{
return System.Reflection.Assembly.ReflectionOnlyLoad(args.Name);
}
That should help with loading types defined in other assemblies.
Hope that helps!

You can use a negative match:
Pattern regex = Pattern.compile("([a-zA-Z0-9])*");
(For zero or more characters)
or
Pattern regex = Pattern.compile("([a-zA-Z0-9])+");
(For one or more characters)
Be sure to have both objects created in controller: @post
and @comment
for the post, eg:
@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)
Then in view:
<%= form_for([@post, @comment]) do |f| %>
Be sure to explicitly define the array in the form_for, not just comma separated like you have above.
Since I got so many negative feedback I realized my solution was wrong so i changed it.
int arr[20] = {1,2,3,4,5};
int index = 5;
void push(int n){
arr[index] = n;
index++;
}
push(6)
New array will contain value from 1 to 6 and you can make function for deletion like this as well.
After downloading all the libraries said by ezaoutis, the error message on my windows 10 persisted, reading the wampserver3.1.3 installation requirements, there was a verification tool called check_vcredist.exe , i ran it and it show me all the missing libraries and it's download links, so i finally could install it succesfully.
Any operating system has processes (p's) running, say p1, p2, p3 and so forth. Each process usually makes an ongoing usage of files.
Each process is consisted of a process tree (or a process table, in another phrasing).
Usually, Operating systems represent each file in each process by a number (that is to say, in each process tree/table).
The first file used in the process is file0, second is file1, third is file2, and so forth.
Any such number is a file descriptor.
File descriptors are usually integers (0, 1, 2 and not 0.5, 1.5, 2.5).
Given we often describe processes as "process-tables", and given that tables has rows (entries) we can say that the file descriptor cell in each entry, uses to represent the whole entry.
In a similar way, when you open a network socket, it has a socket descriptor.
In some operating systems, you can run out of file descriptors, but such case is extremely rare, and the average computer user shouldn't worry from that.
File descriptors might be global (process A starts in say 0, and ends say in 1 ; Process B starts say in 2, and ends say in 3) and so forth, but as far as I know, usually in modern operating systems, file descriptors are not global, and are actually process-specific (process A starts in say 0 and ends say in 5, while process B starts in 0 and ends say in 10).
You can create a MemoryStream from a String and use that in any third-party function that requires a stream. In this case, MemoryStream, with the help of UTF8.GetBytes, provides the functionality of Java's StringStream.
String content = "stuff";
using (MemoryStream stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(content)))
{
Print(stream); //or whatever action you need to perform with the stream
stream.Seek(0, SeekOrigin.Begin); //If you need to use the same stream again, don't forget to reset it.
UseAgain(stream);
}
stream.Seek(0, SeekOrigin.Begin);
string s;
using (var readr = new StreamReader(stream))
{
s = readr.ReadToEnd();
}
//and don't forget to dispose the stream if you created it
No, JavaScript is not a statically typed language. Sometimes you may need to manually check types of parameters in your function body.
You can generate views and controllers for devise customization.
Use
rails g devise:controllers users -c=registrations
and
rails g devise:views
It will copy particular controllers and views from gem to your application.
Next, tell the router to use this controller:
devise_for :users, :controllers => {:registrations => "users/registrations"}

In addition to the accepted answer from 2009. If you can can target modern browsers, one can make use of the Object.defineProperty.
The Object.defineProperty() method defines a new property directly on an object, or modifies an existing property on an object, and returns the object. Source: Mozilla
var Foo = (function () {
function Foo() {
this._bar = false;
}
Object.defineProperty(Foo.prototype, "bar", {
get: function () {
return this._bar;
},
set: function (theBar) {
this._bar = theBar;
},
enumerable: true,
configurable: true
});
Foo.prototype.toTest = function () {
alert("my value is " + this.bar);
};
return Foo;
}());
// test instance
var test = new Foo();
test.bar = true;
test.toTest();

I think you are not configured properly,
if you are using XAMPP then you can easily send mail from localhost.
for example you can configure C:\xampp\php\php.ini
and c:\xampp\sendmail\sendmail.ini
for gmail to send mail.
in C:\xampp\php\php.ini
find extension=php_openssl.dll
and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.
in php.ini file find [mail function]
and change
SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"
(use the above send mail path only and it will work)
Now Open C:\xampp\sendmail\sendmail.ini
. Replace all the existing code in sendmail.ini with following code
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]
Now you have done!! create php file with mail function and send mail from localhost.
Update
First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()
).
You can set the following settings in your PHP.ini:
ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");
localhost:8080/esccapp/tst/submit.jsp?key=datr&key2=datr2&key3=datr3
<%@page import="java.util.Enumeration"%>
<%
Enumeration in = request.getParameterNames();
while(in.hasMoreElements()) {
String paramName = in.nextElement().toString();
out.println(paramName + " = " + request.getParameter(paramName)+"<br>");
}
%>
key = datr
key2 = datr2
key3 = datr3
Try str_detect()
from the stringr package, which detects the presence or absence of a pattern in a string.
Here is an approach that also incorporates the %>%
pipe and filter()
from the dplyr package:
library(stringr)
library(dplyr)
CO2 %>%
filter(str_detect(Treatment, "non"))
Plant Type Treatment conc uptake
1 Qn1 Quebec nonchilled 95 16.0
2 Qn1 Quebec nonchilled 175 30.4
3 Qn1 Quebec nonchilled 250 34.8
4 Qn1 Quebec nonchilled 350 37.2
5 Qn1 Quebec nonchilled 500 35.3
...
This filters the sample CO2 data set (that comes with R) for rows where the Treatment variable contains the substring "non". You can adjust whether str_detect
finds fixed matches or uses a regex - see the documentation for the stringr package.
In Python you may use the in
operator. You can do stuff like this:
>>> "c" in "abc"
True
Taking this further, you can check for complex structures, like tuples:
>>> (2, 4, 8) in ((1, 2, 3), (2, 4, 8))
True
another solution is catching onClick event and for aggregate data to js function you can
.hmtl.erb
<%= link_to "Action", 'javascript:;', class: 'my-class', data: { 'array' => %w(foo bar) } %>
.js
// handle my-class click
$('a.my-class').on('click', function () {
var link = $(this);
var array = link.data('array');
});
So what's the problem,
It's a ’
(RIGHT SINGLE QUOTATION MARK
- U+2019) character which is being decoded as CP-1252 instead of UTF-8. If you check the encodings table, then you see that this character is in UTF-8 composed of bytes 0xE2
, 0x80
and 0x99
. If you check the CP-1252 code page layout, then you'll see that each of those bytes stand for the individual characters â
, €
and ™
.
and how can I fix it?
Use UTF-8 instead of CP-1252 to read, write, store, and display the characters.
I have the Content-Type set to UTF-8 in both my
<head>
tag and my HTTP headers:<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
This only instructs the client which encoding to use to interpret and display the characters. This doesn't instruct your own program which encoding to use to read, write, store, and display the characters in. The exact answer depends on the server side platform / database / programming language used. Do note that the one set in HTTP response header has precedence over the HTML meta tag. The HTML meta tag would only be used when the page is opened from local disk file system instead of from HTTP.
In addition, my browser is set to
Unicode (UTF-8)
:
This only forces the client which encoding to use to interpret and display the characters. But the actual problem is that you're already sending ’
(encoded in UTF-8) to the client instead of ’
. The client is correctly displaying ’
using the UTF-8 encoding. If the client was misinstructed to use, for example ISO-8859-1, you would likely have seen ââ¬â¢
instead.
I am using ASP.NET 2.0 with a database.
This is most likely where your problem lies. You need to verify with an independent database tool what the data looks like.
If the ’
character is there, then you aren't connecting to the database correctly. You need to tell the database connector to use UTF-8.
If your database contains ’
, then it's your database that's messed up. Most probably the tables aren't configured to use UTF-8
. Instead, they use the database's default encoding, which varies depending on the configuration. If this is your issue, then usually just altering the table to use UTF-8 is sufficient. If your database doesn't support that, you'll need to recreate the tables. It is good practice to set the encoding of the table when you create it.
You're most likely using SQL Server, but here is some MySQL code (copied from this article):
CREATE DATABASE db_name CHARACTER SET utf8;
CREATE TABLE tbl_name (...) CHARACTER SET utf8;
If your table is however already UTF-8, then you need to take a step back. Who or what put the data there. That's where the problem is. One example would be HTML form submitted values which are incorrectly encoded/decoded.
Here are some more links to learn more about the problem:
I would suggest you read the appropriate sections in The Java Tutorial from Sun:
http://java.sun.com/docs/books/tutorial/getStarted/cupojava/win32.html
import re
test = "This is a test...we should not be able to see this"
res = re.sub(r'\.\.\..*',"",test)
print(res)
Output: "This is a test"
Some of the system headers provide a forward declaration of std::stringstream
without the definition. This makes it an 'incomplete type'. To fix that you need to include the definition, which is provided in the <sstream>
header:
#include <sstream>
The problem is caused by the fact that cmbDataSourceExtractor.CancelAsync()
is an asynchronous method, the Cancel
operation has not yet completed when cmdDataSourceExtractor.RunWorkerAsync(...)
exitst. You should wait for cmdDataSourceExtractor
to complete before calling RunWorkerAsync
again. How to do this is explained in this SO question.
Listview derives from listbox control. One most important difference is listview uses the extended selection mode by default . listview also adds a property called view which enables you to customize the view in a richer way than a custom itemspanel. One real life example of listview with gridview is file explorer's details view. Listview with grid view is a less powerful data grid. After the introduction of datagrid control listview lost its importance.
Can you invert your regex so split by the non operation characters?
String ops[] = string.split("[a-z]")
// ops == [+, -, *, /, <, >, >=, <=, == ]
This obviously doesn't return the variables in the array. Maybe you can interleave two splits (one by the operators, one by the variables)
Pinal Dave explains this well in his blog.
DECLARE @NewLineChar AS CHAR(2) = CHAR(13) + CHAR(10)
PRINT ('SELECT FirstLine AS FL ' + @NewLineChar + 'SELECT SecondLine AS SL')
conda
is both a command line tool, and a python package.
Miniconda installer = Python + conda
Anaconda installer = Python + conda
+ meta package anaconda
meta Python pkg anaconda
= about 160 Python pkgs for daily use in data science
Anaconda installer = Miniconda installer + conda install anaconda
conda
is a python manager and an environment manager, which makes it possible to
conda install flake8
conda create -n myenv python=3.6
Miniconda installer = Python + conda
conda
, the package manager and environment manager, is a Python package. So Python is installed. Cause conda distribute Python interpreter with its own libraries/dependencies but not the existing ones on your operating system, other minimal dependencies like openssl
, ncurses
, sqlite
, etc are installed as well.
Basically, Miniconda is just conda
and its minimal dependencies. And the environment where conda
is installed is the "base" environment, which is previously called "root" environment.
Anaconda installer = Python + conda
+ meta package anaconda
meta Python package anaconda
= about 160 Python pkgs for daily use in data science
Meta packages, are packages that do NOT contain actual softwares and simply depend on other packages to be installed.
Download an anaconda

If you have a Miniconda installed, conda install anaconda
will make it same as an Anaconda installation, except that the installation folder names are different.
Miniconda2 v.s. Miniconda. Anaconda2 v.s. Anaconda.
2
means the bundled Python interpreter for conda
in the "base" environment is Python 2, but not Python 3.
Don't use enums. Reason #78 to not use enums. :) Use integers, which can easily be remoted through Bundle and Parcelable.
You will get the proxy host and port from your server administrator or support.
After that set up
npm config set http_proxy http://username:[email protected]:itsport
npm config set proxy http://username:[email protected]:itsport
If there any special character in password try with % urlencode. Eg:- pound(hash) shuold be replaced by %23.
This worked for me...
First, this code here,
string [] scripts = new String [] ("test3","test4","test5");
should be
String[] scripts = new String [] {"test3","test4","test5"};
Please read this tutorial on Arrays
Second,
Arrays are fixed size, so you can't add new Strings to above array. You may override existing values
scripts[0] = string1;
(or)
Create array with size then keep on adding elements till it is full.
If you want resizable arrays, consider using ArrayList.
Those who are facing issues in implementing this on react-router v4.
Here is a working solution for navigating through the react app from redux actions.
history.js
import createHistory from 'history/createBrowserHistory'
export default createHistory()
App.js/Route.jsx
import { Router, Route } from 'react-router-dom'
import history from './history'
...
<Router history={history}>
<Route path="/test" component={Test}/>
</Router>
another_file.js OR redux file
import history from './history'
history.push('/test') // this should change the url and re-render Test component

Its a bit late but if you don't want to use a div specifically, I usually do it like this...
var ajax_image = "<img src='/images/Loading.gif' alt='Loading...' />";
$('#ReplaceDiv').html(ajax_image);
ReplaceDiv is the div that the Ajax inserts too. So when it arrives, the image is replaced.
To make a dropdown list you need two properties:
In your case you only have a list of string which cannot be exploited to create a usable drop down list.
While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:
@model List<string>
@Html.DropDownList(
"Foo",
new SelectList(
Model.Select(x => new { Value = x, Text = x }),
"Value",
"Text"
)
)
where Foo
will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:
<select name="Foo" id="Foo">
<option value="item 1">item 1</option>
<option value="item 2">item 2</option>
<option value="item 3">item 3</option>
...
</select>
This being said a far better view model for a drop down list is the following:
public class MyListModel
{
public string SelectedItemId { get; set; }
public IEnumerable<SelectListItem> Items { get; set; }
}
and then:
@model MyListModel
@Html.DropDownListFor(
x => x.SelectedItemId,
new SelectList(Model.Items, "Value", "Text")
)
and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId
property of this view model to the corresponding Value
of some element in the Items
collection.
You should do that in GridView's RowDataBound
event which is triggered for every GridViewRow
after it was databound.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Text = "Date";
}
}
or you can set AutogenerateColumns
to false
and add the columns declaratively on aspx:
<asp:gridview id="GridView1"
onrowdatabound="GridView1_RowDataBound"
autogeneratecolumns="False"
emptydatatext="No data available."
runat="server">
<Columns>
<asp:BoundField DataField="DateField" HeaderText="Date"
SortExpression="DateField" />
</Columns>
</asp:gridview>
python -m compileall <pythonic-project-name>
which compiles all .py
files to .pyc
files in a project which contains packages as well as modules.
python3 -m compileall <pythonic-project-name>
which compiles all .py
files to __pycache__
folders in a project which contains packages as well as modules.
Or with browning from this post:
You can enforce the same layout of
.pyc
files in the folders as in Python2 by using:
python3 -m compileall -b <pythonic-project-name>
The option
-b
triggers the output of.pyc
files to their legacy-locations (i.e. the same as in Python2).
You can combine multiple selectors and this is so cool knowing that you can select every attribute and attribute based on their value like href

Here is a function that is part of the helpRFunctions package that will return a list of all of the various data types in your data frame, as well as the specific variable names associated with that type.
install.package('devtools') # Only needed if you dont have this installed.

install_github('adam-m-mcelhinney/helpRFunctions')
library(helpRFunctions)
my.data <- data.frame(y=rnorm(5),
x1=c(1:5),
x2=c(TRUE, TRUE, FALSE, FALSE, FALSE),
X3=letters[1:5])
t <- list.df.var.types(my.data)
t$factor
t$integer
t$logical
t$numeric
You could then do something like var(my.data[t$numeric])
.
Hope this is helpful!
X-Frame-Options
is deprecated. From MDN:
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.
The modern alternative is the Content-Security-Policy
header, which along many other policies can white-list what URLs are allowed to host your page in a frame, using the frame-ancestors
directive.
frame-ancestors
supports multiple domains and even wildcards, for example:
Content-Security-Policy: frame-ancestors 'self' example.com *.example.net ;
Unfortunately, for now, Internet Explorer does not fully support Content-Security-Policy.
UPDATE: MDN has removed their deprecation comment. Here's a similar comment from W3C's Content Security Policy Level
The
frame-ancestors
directive obsoletes theX-Frame-Options
header. If a resource has both policies, theframe-ancestors
policy SHOULD be enforced and theX-Frame-Options
policy SHOULD be ignored.

One thing you can do is to set your axis range by yourself by using matplotlib.pyplot.axis.
matplotlib.pyplot.axis
from matplotlib import pyplot as plt
plt.axis([0, 10, 0, 20])
0,10 is for x axis range. 0,20 is for y axis range.
or you can also use matplotlib.pyplot.xlim or matplotlib.pyplot.ylim
matplotlib.pyplot.ylim
plt.ylim(-2, 2)
plt.xlim(0,10)
This happens if you're using cocoapods, use the .xcworkspace

Whenever you wish to exit all open activities, you should press a button which loads the first Activity that runs when your application starts then clear all the other activities, then have the last remaining activity finish. to do so apply the following code in ur project
Intent intent = new Intent(getApplicationContext(), FirstActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);
The above code finishes all the activities except for FirstActivity. Then we need to finish the FirstActivity's Enter the below code in Firstactivity's oncreate
if (getIntent().getBooleanExtra("EXIT", false)) {
finish();
}
and you are done....

Here's a decorator for timing functions
let timed = (f) => (...args)=>{
let start = performance.now();
let ret = f(...args);
console.log(`function ${f.name} took ${(performance.now()-start).toFixed(3)}ms`)
return ret;
}
Usage:
let test = ()=>{/*does something*/}
test = timed(test) // turns the function into a timed function in one line
test() // run your code as normal, logs 'function test took 1001.900ms'
If you're using async functions you can make timed
async and add an await
before f(...args), and that should work for those. It gets more complicated if you want one decorator to handle both sync and async functions.
This should work:
var result = cmd.ExecuteScalar();
conn.Close();
return result != null ? result.ToString() : string.Empty;
Also, I'd suggest using Parameters in your query, something like (just a suggestion):
var cmd = new SqlCommand
{
Connection = conn,
CommandType = CommandType.Text,
CommandText = "select COUNT(idemp_atd) absentDayNo from td_atd where absentdate_atd between @sdate and @edate and idemp_atd=@idemp group by idemp_atd"
};
cmd.Parameters.AddWithValue("@sdate", sdate);
cmd.Parameters.AddWithValue("@edate", edate);
// etc ...
You could try:
hadoop fs -put /path/in/linux /hdfs/path

This is in-line with what JP Mercier initially suggested about using Pandas, but with a major modification: If you read data into Pandas in chunks, it should be more malleable. Meaning, that you can parse a much larger file than Pandas can actually handle as a single piece and pass it to Spark in smaller sizes. (This also answers the comment about why one would want to use Spark if they can load everything into Pandas anyways.)
from pyspark import SparkContext
from pyspark.sql import SQLContext
import pandas as pd
sc = SparkContext('local','example') # if using locally
sql_sc = SQLContext(sc)
Spark_Full = sc.emptyRDD()
chunk_100k = pd.read_csv("Your_Data_File.csv", chunksize=100000)
# if you have headers in your csv file:
headers = list(pd.read_csv("Your_Data_File.csv", nrows=0).columns)
for chunky in chunk_100k:
Spark_Full += sc.parallelize(chunky.values.tolist())
YourSparkDataFrame = Spark_Full.toDF(headers)
# if you do not have headers, leave empty instead:
# YourSparkDataFrame = Spark_Full.toDF()
YourSparkDataFrame.show()
If you want to call them like that, you should declare them static.
Do you just mean spaces or all whitespace?
For just spaces, use str_replace:
$string = str_replace(' ', '', $string);
For all whitespace (including tabs and line ends), use preg_replace:
$string = preg_replace('/\s+/', '', $string);
(From here).
One option is to install the cli globally.
Since Babel 7 was released the namespace has changed from babel-cli
to @babel/cli
, hence:
npm install --global @babel/cli
You'll likely still encounter errors for @babel/core
so:
npm install --global @babel/core
You don't really need to do it all in jQuery to do that smoothly. Do it like this:
$(".nextbutton").click(function() {
document.forms["form1"].submit();
});
Also can use without parent
say router definition like:
{path:'/about', name: 'About', component: AboutComponent}
then can navigate by name
instead of path
goToAboutPage() {
this.router.navigate(['About']); // here "About" is name not path
}
Updated for V2.3.0
In Routing from v2.0 name property no more exist. route define without name property. so you should use path instead of name. this.router.navigate(['/path'])
and no leading slash for path so use path: 'about'
instead of path: '/about'
router definition like:
{path:'about', component: AboutComponent}
then can navigate by path
goToAboutPage() {
this.router.navigate(['/about']); // here "About" is path
}
Following the steps will make it 10 times faster and reduce build time 90%
First create a file named gradle.properties in the following directory:
/home/<username>/.gradle/ (Linux)

C:\Users\<username>\.gradle (Windows)
Add this line to the file:
org.gradle.daemon=true
org.gradle.parallel=true
And check this options in Android Studio
This library adds a desiredAccuracy and maxWait option to geolocation calls, which means it will keep trying to get a position until the accuracy is within a specified range.
First, you need to obtain the public certificate from the server you're trying to connect to. That can be done in a variety of ways, such as contacting the server admin and asking for it, using OpenSSL to download it, or, since this appears to be an HTTP server, connecting to it with any browser, viewing the page's security info, and saving a copy of the certificate. (Google should be able to tell you exactly what to do for your specific browser.)
Now that you have the certificate saved in a file, you need to add it to your JVM's trust store. At $JAVA_HOME/jre/lib/security/
for JREs or $JAVA_HOME/lib/security
for JDKs, there's a file named cacerts
, which comes with Java and contains the public certificates of the well-known Certifying Authorities. To import the new cert, run keytool as a user who has permission to write to cacerts:
keytool -import -file <the cert file> -alias <some meaningful name> -keystore <path to cacerts file>
It will most likely ask you for a password. The default password as shipped with Java is changeit
. Almost nobody changes it. After you complete these relatively simple steps, you'll be communicating securely and with the assurance that you're talking to the right server and only the right server (as long as they don't lose their private key).
Use;

Suppose your dataframe is df and you want to change gender from 2 to 1 in participant id 5 then you should determine the row by writing "==" as you can see

Assuming you are invoking g++ from the command line (terminal):
$ g++ -std=c++11 your_file.cpp -o your_program
or
$ g++ -std=c++0x your_file.cpp -o your_program

NB: Should you want the year to be based on some reference date, the code below calculates the dates for the between
statement:
declare @referenceTime datetime = getutcdate()
select *
from myTable
where SomeDate
between dateadd(year, year(@referenceTime) - 1900, '01-01-1900') --1st Jan this year (midnight)
and dateadd(millisecond, -3, dateadd(year, year(@referenceTime) - 1900, '01-01-1901')) --31st Dec end of this year (just before midnight of the new year)
Similarly, if you're using a year value, swapping year(@referenceDate)
for your reference year's value will work
declare @referenceYear int = 2010
select *
from myTable
where SomeDate
between dateadd(year,@referenceYear - 1900, '01-01-1900') --1st Jan this year (midnight)
and dateadd(millisecond, -3, dateadd(year,@referenceYear - 1900, '01-01-1901')) --31st Dec end of this year (just before midnight of the new year)

If you are using the same x and y values that you supplied in the ggplot()
call and need to plot the linear regression line then you don't need to use the formula inside geom_smooth()
, just supply the method="lm"
.
ggplot(data,aes(x.plot, y.plot)) +
