The definitive solution is to allow the InfoTech protocol to work in the intranet zone.

Add the following value to the registry and the problem should be solved:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000001

I have a slightly different perspective on the difference between a DATETIME and a TIMESTAMP. A DATETIME stores a literal value of a date and time with no reference to any particular timezone. So, I can set a DATETIME column to a value such as '2019-01-16 12:15:00' to indicate precisely when my last birthday occurred. Was this Eastern Standard Time? Pacific Standard Time? Who knows? Where the current session time zone of the server comes into play occurs when you set a DATETIME column to some value such as NOW(). The value stored will be the current date and time using the current session time zone in effect. But once a DATETIME column has been set, it will display the same regardless of what the current session time zone is.

A TIMESTAMP column on the other hand takes the '2019-01-16 12:15:00' value you are setting into it and interprets it in the current session time zone to compute an internal representation relative to 1/1/1970 00:00:00 UTC. When the column is displayed, it will be converted back for display based on whatever the current session time zone is. It's a useful fiction to think of a TIMESTAMP as taking the value you are setting and converting it from the current session time zone to UTC for storing and then converting it back to the current session time zone for displaying.

If my server is in San Francisco but I am running an event in New York that starts on 9/1/1029 at 20:00, I would use a TIMESTAMP column for holding the start time, set the session time zone to 'America/New York' and set the start time to '2009-09-01 20:00:00'. If I want to know whether the event has occurred or not, regardless of the current session time zone setting I can compare the start time with NOW(). Of course, for displaying in a meaningful way to a perspective customer, I would need to set the correct session time zone. If I did not need to do time comparisons, then I would probably be better off just using a DATETIME column, which will display correctly (with an implied EST time zone) regardless of what the current session time zone is.

TIMESTAMP LIMITATION

The TIMESTAMP type has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC and so it may not usable for your particular application. In that case you will have to use a DATETIME type. You will, of course, always have to be concerned that the current session time zone is set properly whenever you are using this type with date functions such as NOW().

since your local username on your laptop frequently does not match the server's username, you can set this in the ~/.subversion/servers file

Add the server to the [groups] section with a name, then add a section with that name and provide a username.

for example, for a login like [email protected] this is what your config would look like:

[groups]
exampleserver = svn.example.com

[exampleserver]
username = me

Since the main method is static and the fxn() method is not, you can't call the method without first creating a Two object. So either you change the method to:

public static int fxn(int y) {
    y = 5;
    return y;
}

or change the code in main to:

Two two = new Two();
x = two.fxn(x);

Read more on static here in the Java Tutorials.

The List<> constructor can accept anything which implements IEnumerable, therefore...

        object[] testArray = new object[] { "blah", "blah2" };
        List<object> testList = new List<object>(testArray);

(int) (longType + 0)

but Long can not exceed the maximum :)

I fear i incur upset reactions but nevertheless, to clarify for me if i'm wrong or those seeing this question and being interested in an answer:

my understanding of https://tools.ietf.org/html/rfc1122 whose status is "an official specification" and as such is the reference for the terminology used in this question and which is neither superseded by another RFC nor has errata contradicting the following:

theoretically, ie. based on the written spec., UDP like given by https://tools.ietf.org/html/rfc1122#section-4 has no "packet size". Thus the answer could be "indefinite"

In practice, which is what this questions likely seeked (and which could be updated for current tech in action), this might be different and I don't know.

I apologize if i caused upsetting. https://tools.ietf.org/html/rfc1122#page-8 The "Internet Protocol Suite" and "Architectural Assumptions" don't make clear to me the "assumption" i was on, based on what I heard, that the layers are separate. Ie. the layer UDP is in does not have to concern itself with the layer IP is in (and the IP layer does have things like Reassembly, EMTU_R, Fragmentation and MMS_R (https://tools.ietf.org/html/rfc1122#page-56))

It's evident that you've managed to mess up your PATH variable. (Your current PATH doesn't contain any location where common utilities are located.)

Try:

PATH=/bin:/usr/bin:/usr/local/bin:${PATH}
export PATH

Alternatively, for "resetting" zsh, specify the complete path to the shell:

exec /bin/zsh

or

exec /usr/bin/zsh

Just to clarify, be aware bracket placement is important!

These can be added to any HTML tags... span, div, table, p, tr, td etc.

AngularJS

ng-if="check1 && !check2" -- AND NOT
ng-if="check1 || check2" -- OR
ng-if="(check1 || check2) && check3" -- AND/OR - Make sure to use brackets

Angular2+

*ngIf="check1 && !check2" -- AND NOT
*ngIf="check1 || check2" -- OR
*ngIf="(check1 || check2) && check3" -- AND/OR - Make sure to use brackets

It's best practice not to do calculations directly within ngIfs, so assign the variables within your component, and do any logic there.

boolean check1 = Your conditional check here...
...

I think this confusing exception occurs when you use a variable in a lambda which is a null-reference at run-time. In your case, I would check if your variable calculationViewModel is a null-reference.

Something like:

public ActionResult MNPurchase()
{
    CalculationViewModel calculationViewModel = (CalculationViewModel)TempData["calculationViewModel"];

    if (calculationViewModel != null)
    {
        decimal OP = landTitleUnitOfWork.Sales.Find()
            .Where(x => x.Min >= calculationViewModel.SalesPrice)
            .FirstOrDefault()
            .OP;

        decimal MP = landTitleUnitOfWork.Sales.Find()
            .Where(x => x.Min >= calculationViewModel.MortgageAmount)
            .FirstOrDefault()
            .MP;

        calculationViewModel.LoanAmount = (OP + 100) - MP;
        calculationViewModel.LendersTitleInsurance = (calculationViewModel.LoanAmount + 850);

        return View(calculationViewModel);
    }
    else
    {
        // Do something else...
    }
}

You could use toArray() to convert into an array of Objects followed by this method to convert the array of Objects into an array of Strings:

Object[] objectArray = lst.toArray();
String[] stringArray = Arrays.copyOf(objectArray, objectArray.length, String[].class);

Firstly, check the IP address that your application has bound to. It could only be binding to a local address, for example, which would mean that you'd never see it from a different machine regardless of firewall states.

You could try using a portscanner like nmap to see if the port is open and visible externally... it can tell you if the port is closed (there's nothing listening there), open (you should be able to see it fine) or filtered (by a firewall, for example).

To answer your first question, numpy.correlate(a, v, mode) is performing the convolution of a with the reverse of v and giving the results clipped by the specified mode. The definition of convolution, C(t)=? _{-8 < i < 8} a_iv_t+i where -8 < t < 8, allows for results from -8 to 8, but you obviously can't store an infinitely long array. So it has to be clipped, and that is where the mode comes in. There are 3 different modes: full, same, & valid:

• "full" mode returns results for every t where both a and v have some overlap.
• "same" mode returns a result with the same length as the shortest vector (a or v).
• "valid" mode returns results only when a and v completely overlap each other. The documentation for numpy.convolve gives more detail on the modes.

For your second question, I think numpy.correlate is giving you the autocorrelation, it is just giving you a little more as well. The autocorrelation is used to find how similar a signal, or function, is to itself at a certain time difference. At a time difference of 0, the auto-correlation should be the highest because the signal is identical to itself, so you expected that the first element in the autocorrelation result array would be the greatest. However, the correlation is not starting at a time difference of 0. It starts at a negative time difference, closes to 0, and then goes positive. That is, you were expecting:

autocorrelation(a) = ? _{-8 < i < 8} a_iv_t+i where 0 <= t < 8

But what you got was:

autocorrelation(a) = ? _{-8 < i < 8} a_iv_t+i where -8 < t < 8

What you need to do is take the last half of your correlation result, and that should be the autocorrelation you are looking for. A simple python function to do that would be:

def autocorr(x):
    result = numpy.correlate(x, x, mode='full')
    return result[result.size/2:]

You will, of course, need error checking to make sure that x is actually a 1-d array. Also, this explanation probably isn't the most mathematically rigorous. I've been throwing around infinities because the definition of convolution uses them, but that doesn't necessarily apply for autocorrelation. So, the theoretical portion of this explanation may be slightly wonky, but hopefully the practical results are helpful. These pages on autocorrelation are pretty helpful, and can give you a much better theoretical background if you don't mind wading through the notation and heavy concepts.

This is what worked for me on windows:

Edit the pg_hba.conf file locates at C:\Program Files\PostgreSQL\9.3\data.

# IPv4 local connections: host all all 127.0.0.1/32 trust

Change the method from trust to md5 and restart the postgres service on windows.

After that, you can login using postgres user without password by using pgadmin. You can change password using File->Change password.

If postgres user does not have superuser privileges , then you cannot change the password. In this case , login with another user(pgsql)with superuser access and provide privileges to other users by right clicking on users and selecting properties->Role privileges.

1NF: Only one value per column

2NF: All the non primary key columns in the table should depend on the entire primary key.

3NF: All the non primary key columns in the table should depend DIRECTLY on the entire primary key.

I have written an article in more detail over here

An even simpler awk solution w/o a program:

awk -v ORS='\r\n' '1' unix.txt > dos.txt

Technically '1' is your program, b/c awk requires one when given option.

UPDATE: After revisiting this page for the first time in a long time I realized that no one has yet posted an internal solution, so here is one:

while IFS= read -r line;
do printf '%s\n' "${line%$'\r'}";
done < dos.txt > unix.txt

Note the "" at the beginning and at the end!

Run a program and pass a Long Filename

cmd /c write.exe "c:\sample documents\sample.txt"

Spaces in Program Path

cmd /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in Program Path + parameters

cmd /c ""c:\Program Files\demo.cmd"" Parameter1 Param2

Spaces in Program Path + parameters with spaces

cmd /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch Demo1 and then Launch Demo2

cmd /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

CMD.exe (Command Shell)

You can do it with a separate UPDATE statement

UPDATE report.TEST target
SET    is Deleted = 'Y'
WHERE  NOT EXISTS (SELECT 1
                   FROM   main.TEST source
                   WHERE  source.ID = target.ID);

I don't know of any way to integrate this into your MERGE statement.

Though the complete difference is more complicated, the only difference that concerns me is when the machine creates the function object. Which in the case of declarations is before any statement is executed but after a statement body is invoked (be that the global code body or a sub-function's), and in the case of expressions is when the statement it is in gets executed. Other than that for all intents and purposes browsers treat them the same.

To help you understand, take a look at this performance test which busted an assumption I had made of internally declared functions not needing to be re-created by the machine when the outer function is invoked. Kind of a shame too as I liked writing code that way.

When I had this error, it went away after I my computer crashed and restarted. Try closing and reopening your IDE, if that doesn't work, try restarting your computer. I had just installed the libraries at that point without restarting pycharm when I got this error.

Never closed PyCharm first to test because my blasted computer keeps crashing randomly... working on that one, but it at least solved this problem.. little victories.. :).

In TypeScript you can do a type assertion using an interface and generics like so:

var json = Utilities.JSONLoader.loadFromFile("../docs/location_map.json");
var locations: Array<ILocationMap> = JSON.parse(json).location;

Where ILocationMap describes the shape of your data. The advantage of this method is that your JSON could contain more properties but the shape satisfies the conditions of the interface.

However, this does NOT add class instance methods.

I'd like to add: Favoring "Elegant" code over highly performing code. The code that works best against databases is often ugly to the application developer's eye.

Believing that nonsense about premature optimization. Databases must consider performance in the original design and in any subsequent development. Performance is 50% of database design (40% is data integrity and the last 10% is security) in my opinion. Databases which are not built from the bottom up to perform will perform badly once real users and real traffic are placed against the database. Premature optimization doesn't mean no optimization! It doesn't mean you should write code that will almost always perform badly because you find it easier (cursors for example which should never be allowed in a production database unless all else has failed). It means you don't need to look at squeezing out that last little bit of performance until you need to. A lot is known about what will perform better on databases, to ignore this in design and development is short-sighted at best.

Slightly modified from: Python Pandas Dataframe: Normalize data between 0.01 and 0.99? but from some of the comments thought it was relevant (sorry if considered a repost though...)

I wanted customized normalization in that regular percentile of datum or z-score was not adequate. Sometimes I knew what the feasible max and min of the population were, and therefore wanted to define it other than my sample, or a different midpoint, or whatever! This can often be useful for rescaling and normalizing data for neural nets where you may want all inputs between 0 and 1, but some of your data may need to be scaled in a more customized way... because percentiles and stdevs assumes your sample covers the population, but sometimes we know this isn't true. It was also very useful for me when visualizing data in heatmaps. So i built a custom function (used extra steps in the code here to make it as readable as possible):

def NormData(s,low='min',center='mid',hi='max',insideout=False,shrinkfactor=0.):    
    if low=='min':
        low=min(s)
    elif low=='abs':
        low=max(abs(min(s)),abs(max(s)))*-1.#sign(min(s))
    if hi=='max':
        hi=max(s)
    elif hi=='abs':
        hi=max(abs(min(s)),abs(max(s)))*1.#sign(max(s))

    if center=='mid':
        center=(max(s)+min(s))/2
    elif center=='avg':
        center=mean(s)
    elif center=='median':
        center=median(s)

    s2=[x-center for x in s]
    hi=hi-center
    low=low-center
    center=0.

    r=[]

    for x in s2:
        if x<low:
            r.append(0.)
        elif x>hi:
            r.append(1.)
        else:
            if x>=center:
                r.append((x-center)/(hi-center)*0.5+0.5)
            else:
                r.append((x-low)/(center-low)*0.5+0.)

    if insideout==True:
        ir=[(1.-abs(z-0.5)*2.) for z in r]
        r=ir

    rr =[x-(x-0.5)*shrinkfactor for x in r]    
    return rr

This will take in a pandas series, or even just a list and normalize it to your specified low, center, and high points. also there is a shrink factor! to allow you to scale down the data away from endpoints 0 and 1 (I had to do this when combining colormaps in matplotlib:Single pcolormesh with more than one colormap using Matplotlib) So you can likely see how the code works, but basically say you have values [-5,1,10] in a sample, but want to normalize based on a range of -7 to 7 (so anything above 7, our "10" is treated as a 7 effectively) with a midpoint of 2, but shrink it to fit a 256 RGB colormap:

#In[1]
NormData([-5,2,10],low=-7,center=1,hi=7,shrinkfactor=2./256)
#Out[1]
[0.1279296875, 0.5826822916666667, 0.99609375]

It can also turn your data inside out... this may seem odd, but I found it useful for heatmapping. Say you want a darker color for values closer to 0 rather than hi/low. You could heatmap based on normalized data where insideout=True:

#In[2]
NormData([-5,2,10],low=-7,center=1,hi=7,insideout=True,shrinkfactor=2./256)
#Out[2]
[0.251953125, 0.8307291666666666, 0.00390625]

So now "2" which is closest to the center, defined as "1" is the highest value.

Anyways, I thought my application was relevant if you're looking to rescale data in other ways that could have useful applications to you.

You could actually put the value = to the text and then do

$j(document).ready(function(){
    $j("select#select_2").change(function(){
        val = $j("#select_2 option:selected").html();
        alert(val);
    });
});

Or what I did on a similar case was

<select name="options[2]" id="select_2" onChange="JavascriptMethod()">
  with you're options here
</select>

With this second option you should have a undefined. Give me feedback if it worked :)

Patrick

here is a jsfiddle with an example of showing/hiding div's via a select.

HTML:

<div id="option1" class="group">asdf</div>
<div id="option2" class="group">kljh</div>
<div id="option3" class="group">zxcv</div>
<div id="option4" class="group">qwerty</div>
<select id="selectMe">
  <option value="option1">option1</option>
  <option value="option2">option2</option>
  <option value="option3">option3</option>
  <option value="option4">option4</option>
</select>

jQuery:

$(document).ready(function () {
  $('.group').hide();
  $('#option1').show();
  $('#selectMe').change(function () {
    $('.group').hide();
    $('#'+$(this).val()).show();
  })
});

The answers here offer many ways to potentially fix this issue, but most will not work for devices with touchscreens. I think the source of the problem stems from these lines of code from the source:

if (type === 'iframe' && isTouch) {
    coming.scrolling = 'scroll';
}

This seems to override any options set by the fancybox initial configuration, and can only be changed after these lines of code have run, i.e. changing the css using the afterShow method. However, all such methods will cause a noticeable delay/lag and you will be able to see the scrollbars disappear as you open it.

My suggested fix is that you remove these lines from the main source file jquery.fancybox.js around line 880, because I don't see a reason to force scrollbars onto devices with touchscreens.

Note that this won't immediately make the scrollbars disappear, it simply stops it from overriding the scrolling configuration option. So you should also add scrolling: 'no' to your fancybox initial configuration.

I would add something to the solution of leonvian, so if by any chance the string is not found among the resources (return value 0, that is not a valid resource code), the function might return something :

private String getStringResourceByName(String aString) {
    String packageName = getPackageName();
    int resId = getResources()
            .getIdentifier(aString, "string", packageName);
    if (resId == 0) {
        return aString;
    } else {
        return getString(resId);
    }
}

Although Reed Copsey and Marc Gravell already described about IQueryable (and also IEnumerable) enough,mI want to add little more here by providing a small example on IQueryable and IEnumerable as many users asked for it

Example: I have created two table in database

   CREATE TABLE [dbo].[Employee]([PersonId] [int] NOT NULL PRIMARY KEY,[Gender] [nchar](1) NOT NULL)
   CREATE TABLE [dbo].[Person]([PersonId] [int] NOT NULL PRIMARY KEY,[FirstName] [nvarchar](50) NOT NULL,[LastName] [nvarchar](50) NOT NULL)

The Primary key(PersonId) of table Employee is also a forgein key(personid) of table Person

Next i added ado.net entity model in my application and create below service class on that

public class SomeServiceClass
{   
    public IQueryable<Employee> GetEmployeeAndPersonDetailIQueryable(IEnumerable<int> employeesToCollect)
    {
        DemoIQueryableEntities db = new DemoIQueryableEntities();
        var allDetails = from Employee e in db.Employees
                         join Person p in db.People on e.PersonId equals p.PersonId
                         where employeesToCollect.Contains(e.PersonId)
                         select e;
        return allDetails;
    }

    public IEnumerable<Employee> GetEmployeeAndPersonDetailIEnumerable(IEnumerable<int> employeesToCollect)
    {
        DemoIQueryableEntities db = new DemoIQueryableEntities();
        var allDetails = from Employee e in db.Employees
                         join Person p in db.People on e.PersonId equals p.PersonId
                         where employeesToCollect.Contains(e.PersonId)
                         select e;
        return allDetails;
    }
}

they contains same linq. It called in program.cs as defined below

class Program
{
    static void Main(string[] args)
    {
        SomeServiceClass s= new SomeServiceClass(); 

        var employeesToCollect= new []{0,1,2,3};

        //IQueryable execution part
        var IQueryableList = s.GetEmployeeAndPersonDetailIQueryable(employeesToCollect).Where(i => i.Gender=="M");            
        foreach (var emp in IQueryableList)
        {
            System.Console.WriteLine("ID:{0}, EName:{1},Gender:{2}", emp.PersonId, emp.Person.FirstName, emp.Gender);
        }
        System.Console.WriteLine("IQueryable contain {0} row in result set", IQueryableList.Count());

        //IEnumerable execution part
        var IEnumerableList = s.GetEmployeeAndPersonDetailIEnumerable(employeesToCollect).Where(i => i.Gender == "M");
        foreach (var emp in IEnumerableList)
        {
           System.Console.WriteLine("ID:{0}, EName:{1},Gender:{2}", emp.PersonId, emp.Person.FirstName, emp.Gender);
        }
        System.Console.WriteLine("IEnumerable contain {0} row in result set", IEnumerableList.Count());

        Console.ReadKey();
    }
}

The output is same for both obviously

ID:1, EName:Ken,Gender:M  
ID:3, EName:Roberto,Gender:M  
IQueryable contain 2 row in result set  
ID:1, EName:Ken,Gender:M  
ID:3, EName:Roberto,Gender:M  
IEnumerable contain 2 row in result set

So the question is what/where is the difference? It does not seem to have any difference right? Really!!

Let's have a look on sql queries generated and executed by entity framwork 5 during these period

IQueryable execution part

--IQueryableQuery1 
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE ([Extent1].[PersonId] IN (0,1,2,3)) AND (N'M' = [Extent1].[Gender])

--IQueryableQuery2
SELECT 
[GroupBy1].[A1] AS [C1]
FROM ( SELECT 
    COUNT(1) AS [A1]
    FROM [dbo].[Employee] AS [Extent1]
    WHERE ([Extent1].[PersonId] IN (0,1,2,3)) AND (N'M' = [Extent1].[Gender])
)  AS [GroupBy1]

IEnumerable execution part

--IEnumerableQuery1
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE [Extent1].[PersonId] IN (0,1,2,3)

--IEnumerableQuery2
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE [Extent1].[PersonId] IN (0,1,2,3)

Common script for both execution part

/* these two query will execute for both IQueryable or IEnumerable to get details from Person table
   Ignore these two queries here because it has nothing to do with IQueryable vs IEnumerable
--ICommonQuery1 
exec sp_executesql N'SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[FirstName] AS [FirstName], 
[Extent1].[LastName] AS [LastName]
FROM [dbo].[Person] AS [Extent1]
WHERE [Extent1].[PersonId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=1

--ICommonQuery2
exec sp_executesql N'SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[FirstName] AS [FirstName], 
[Extent1].[LastName] AS [LastName]
FROM [dbo].[Person] AS [Extent1]
WHERE [Extent1].[PersonId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=3
*/

So you have few questions now, let me guess those and try to answer them

Why are different scripts generated for same result?

Lets find out some points here,

all queries has one common part

WHERE [Extent1].[PersonId] IN (0,1,2,3)

why? Because both function IQueryable<Employee> GetEmployeeAndPersonDetailIQueryable and IEnumerable<Employee> GetEmployeeAndPersonDetailIEnumerable of SomeServiceClass contains one common line in linq queries

where employeesToCollect.Contains(e.PersonId)

Than why is the AND (N'M' = [Extent1].[Gender]) part is missing in IEnumerable execution part, while in both function calling we used Where(i => i.Gender == "M") inprogram.cs`

Now we are in the point where difference came between IQueryable and IEnumerable

What entity framwork does when an IQueryable method called, it tooks linq statement written inside the method and try to find out if more linq expressions are defined on the resultset, it then gathers all linq queries defined until the result need to fetch and constructs more appropriate sql query to execute.

It provide a lots of benefits like,

• only those rows populated by sql server which could be valid by the whole linq query execution
• helps sql server performance by not selecting unnecessary rows
• network cost get reduce

like here in example sql server returned to application only two rows after IQueryable execution` but returned THREE rows for IEnumerable query why?

In case of IEnumerable method, entity framework took linq statement written inside the method and constructs sql query when result need to fetch. it does not include rest linq part to constructs the sql query. Like here no filtering is done in sql server on column gender.

But the outputs are same? Because 'IEnumerable filters the result further in application level after retrieving result from sql server

SO, what should someone choose? I personally prefer to define function result as IQueryable<T> because there are lots of benefit it has over IEnumerable like, you could join two or more IQueryable functions, which generate more specific script to sql server.

Here in example you can see an IQueryable Query(IQueryableQuery2) generates a more specific script than IEnumerable query(IEnumerableQuery2) which is much more acceptable in my point of view.

This is how I organized my application's static resources.

If you're not joining two dictionaries, but adding new key-value pairs to a dictionary, then using the subscript notation seems like the best way.

import timeit

timeit.timeit('dictionary = {"karga": 1, "darga": 2}; dictionary.update({"aaa": 123123, "asd": 233})')
>> 0.49582505226135254

timeit.timeit('dictionary = {"karga": 1, "darga": 2}; dictionary["aaa"] = 123123; dictionary["asd"] = 233;')
>> 0.20782899856567383

However, if you'd like to add, for example, thousands of new key-value pairs, you should consider using the update() method.

I once needed to upload PDFs to an online backup archive. But the backup would fail if the user had the file open in another program (such as PDF reader). In my haste, I attempted a few of the top answers in this thread but could not get them to work. What did work for me was trying to move the PDF file to its own directory. I found that this would fail if the file was open in another program, and if the move were successful there would be no restore-operation required as there would be if it were moved to a separate directory. I want to post my basic solution in case it may be useful for others' specific use cases.

string str_path_and_name = str_path + '\\' + str_filename;
FileInfo fInfo = new FileInfo(str_path_and_name);
bool open_elsewhere = false;
try
{
    fInfo.MoveTo(str_path_and_name);
}
catch (Exception ex)
{
    open_elsewhere = true;
}

if (open_elsewhere)
{
    //handle case
}

class MyController < ApplicationController
    # include your helper
    include MyHelper
    # or Rails helper
    include ActionView::Helpers::NumberHelper

    def my_action
      price = number_to_currency(10000)
    end
end

In Rails 5+ simply use helpers (helpers.number_to_currency(10000))

The following is the correct overload (in your example you are missing a closing } to the routeValues anonymous object so your code will throw an exception):

<a href="<%: Url.Action("GetByList", "Listing", new { name = "John", contact = "calgary, vancouver" }) %>">
    <span>People</span>
</a>

Assuming you are using the default routes this should generate the following markup:

<a href="/Listing/GetByList?name=John&amp;contact=calgary%2C%20vancouver">
    <span>People</span>
</a>

which will successfully invoke the GetByList controller action passing the two parameters:

public ActionResult GetByList(string name, string contact) 
{
    ...
}

<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
    <script>
        function systemip(){
        document.getElementById("ip").value = myip
        console.log(document.getElementById("ip").value)
        }
    </script>

The following code will replace all non ASCII characters with question marks.

"".join([x if ord(x) < 128 else '?' for x in s])

Assuming your WebSocket server is listening on the same port as from which the page is being requested, I would suggest:

function createWebSocket(path) {
    var protocolPrefix = (window.location.protocol === 'https:') ? 'wss:' : 'ws:';
    return new WebSocket(protocolPrefix + '//' + location.host + path);
}

Then, for your case, call it as follows:

var socket = createWebSocket(location.pathname + '/to/ws');

I came to this question looking to solve the "too many open files" error, but I am using requests.session() in my code. A few searches later and I came up with an answer on the Python Requests Documentation which suggests to use the with block so that the session is closed even if there are unhandled exceptions:

with requests.Session() as s:
    s.get('http://google.com')

If you're not using Session you can actually do the same thing: https://2.python-requests.org/en/master/user/advanced/#session-objects

with requests.get('http://httpbin.org/get', stream=True) as r:
    # Do something

Responding to your question about List<T>:

List<T> is a class; specifying an interface allows more flexibility of implementation. A better question is "why not IList<T>?"

To answer that question, consider what IList<T> adds to ICollection<T>: integer indexing, which means the items have some arbitrary order, and can be retrieved by reference to that order. This is probably not meaningful in most cases, since items probably need to be ordered differently in different contexts.

Geany has a plugin for markdown which does a fair job, giving you also a Markdown preview in the sidebar. It also runs on Linux, Mac OS X and Windows.

To use it, install geany, then install the package geany-plugin-markdown and select it from the plugin manager.

Check out fontsquirrel. They have a web font generator, which will also spit out a suitable stylesheet for your font (look for "@font-face kit"). This stylesheet can be included in your own, or you can use it as a template.

I use something similar (basically it's the same approach). Sometimes it's useful to have a mock object return pre-defined output for certain inputs. That goes like this:

private Hashtable<InputObject,  OutputObject> table = new Hashtable<InputObject, OutputObject>();
table.put(input1, ouput1);
table.put(input2, ouput2);

...

when(mockObject.method(any(InputObject.class))).thenAnswer(
       new Answer<OutputObject>()
       {
           @Override
           public OutputObject answer(final InvocationOnMock invocation) throws Throwable
           {
               InputObject input = (InputObject) invocation.getArguments()[0];
               if (table.containsKey(input))
               {
                   return table.get(input);
               }
               else
               {
                   return null; // alternatively, you could throw an exception
               }
           }
       }
       );

None of the above worked for me.

But this did:

{{ (num1_str * 1) + (num2_str * 1) }}

In VB.NET, you need to use the GetType method to retrieve the type of an instance of an object, and the GetType() operator to retrieve the type of another known type.

Once you have the two types, you can simply compare them using the Is operator.

So your code should actually be written like this:

Sub FillCategories(ByVal Obj As Object)
    Dim cmd As New SqlCommand("sp_Resources_Categories", Conn)
    cmd.CommandType = CommandType.StoredProcedure
    Obj.DataSource = cmd.ExecuteReader
    If Obj.GetType() Is GetType(System.Web.UI.WebControls.DropDownList) Then

    End If
    Obj.DataBind()
End Sub

You can also use the TypeOf operator instead of the GetType method. Note that this tests if your object is compatible with the given type, not that it is the same type. That would look like this:

If TypeOf Obj Is System.Web.UI.WebControls.DropDownList Then

End If

Totally trivial, irrelevant nitpick: Traditionally, the names of parameters are camelCased (which means they always start with a lower-case letter) when writing .NET code (either VB.NET or C#). This makes them easy to distinguish at a glance from classes, types, methods, etc.

I had a similar issue. You won't be able to ping the VM's from external devices if using NAT setting from within VMware's networking options. I switched to bridged connection so that the guest virtual machine will get it's own IP address and and then I added a second adapter set to NAT for the guest to get to the Internet.

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

One way I like to use is Vanilla JavaScript with template literal:

var templateLiteral = [`
    <!-- HTML_CODE_COMES_HERE -->
`]

var head = document.querySelector("head");
head.innerHTML = templateLiteral;

To redirect output for all prints, you can do this:

import sys
with open('c:\\goat.txt', 'w') as f:
    sys.stdout = f
    print "test"

Another solution:

<template>
  <div :style="cssProps"></div>
</template>

<script>
  export default {
    data() {
      return {
        cssProps: {
          backgroundImage: `url(${require('@/assets/path/to/your/img.jpg')})`
        }
      }
    }
  }
</script>

What makes this solution more convenient? Firstly, it's cleaner. And then, if you're using Vue CLI (I assume you do), you can load it with webpack.

Note: don't forget that require() is always relative to the current file's path.

[+]is simpler

    String s = "ddjdjdj+kfkfkf";

    if(s.contains ("+"))
    {
        String parts[] = s.split("[+]");
        s =  parts[0]; // i want to strip part after  +
    }
    System.out.println(s);

You have different line endings in the example texts in Debuggex. What is especially interesting is that Debuggex seems to have identified which line ending style you used first, and it converts all additional line endings entered to that style.

I used Notepad++ to paste sample text in Unix and Windows format into Debuggex, and whichever I pasted first is what that session of Debuggex stuck with.

So, you should wash your text through your text editor before pasting it into Debuggex. Ensure that you're pasting the style you want. Debuggex defaults to Unix style (\n).

Also, NEL (\u0085) is something different entirely: https://en.wikipedia.org/wiki/Newline#Unicode

(\r?\n) will cover Unix and Windows. You'll need something more complex, like (\r\n|\r|\n), if you want to match old Mac too.

would this work?

cat requirements.txt | while read x; do conda install "$x" -p ./lib ;done

or

conda install --file requirements.txt -p ./lib

If you can not use it directly and if you encounter this error: Blocked a frame with origin "http://www..com" from accessing a cross-origin frame. You can use postMessage() instead of using the function directly.

I had the similar problem and solved it by doing following.

• Download sqljdbc4.jar from the Microsoft website to your local machine.
  
• Right click on Project-->Import-->Maven-->Install or deploy an artifact to a Maven repository as shown below.
  
  

* Next-->Fill the following details

Artifact file: path of the jar you downloaded (Ex: E:\lib\sqljdbc4.jar in my case)
Group Id: com.microsoft.sqlserver
Artifact Id: sqljdbc4
Version: 4.0

• Then Refresh/clean the project.
  
  Thank you!

I ran into the same issue and the above answers didn't help. I need to debug and find it.

 <dependency>
        <groupId>org.apache.hadoop</groupId>

After excluding the jsp-api, it worked for me.

use .html() along with selector to get/set HTML:

 $('#detailInfo').html('changed value');

There are three things to consider here:

1. Don't assume that the sd card is mounted at /sdcard (May be true in the default case, but better not to hard code.). You can get the location of sdcard by querying the system:

   Environment.getExternalStorageDirectory();
   

2. You have to inform Android that your application needs to write to external storage by adding a uses-permission entry in the AndroidManifest.xml file:

   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
   

3. If this directory already exists, then mkdir is going to return false. So check for the existence of the directory, and then try creating it if it does not exist. In your component, use something like:

   File folder = new File(Environment.getExternalStorageDirectory() + "/map");
   boolean success = true;
   if (!folder.exists()) {
       success = folder.mkdir();
   }
   if (success) {
       // Do something on success
   } else {
       // Do something else on failure 
   }
   

When you define different build configurations in your visual studio solution for your projects using a tool like ConfigurationTransform, you may want your Teamcity build, to build you a specified build configuration. You may have build configurations e.g., Debug, Release, Dev, UAT, Prod etc defined. This means, you will have MSBuild Configuration transformation setup for the different configurations. These different configurations are usually used when you have different configurations, e.g. different database connection strings, for the different environment. This is very common because you would have a different database for your production environment from your playground development environment.

They say a picture is worth a thousand words, please see the image below how you would specify multiple build configurations in Teamcity.

In the commandline input text box, specify as below

/p:OutputPath=Publish;Configuration=Dev

Here, I have specified two commandline build configurations/arguments OutputPath and build Configuration with values Publish and Dev respectively, but it could have been, UAT or Prod configuration. If you want more, simply separate them by semi-colon,;

String time = "12:32:22";
String[] values = time.split(":");

This will take your time and split it where it sees a colon and put the value in an array, so you should have 3 values after this.

Then loop through string array and convert each one. (with Integer.parseInt)

Before searching with regex like [A-Z], you should press the case sensitive button (or Alt+C) (as leemour nicely suggested to be edited in the accepted answer). Just to be clear, I'm leaving a few other examples:

1. Capitalize words
   • Find: (\s)([a-z]) (\s also matches new lines, i.e. "venuS" => "VenuS")
   • Replace: $1\u$2
2. Uncapitalize words
   • Find: (\s)([A-Z])
   • Replace: $1\l$2
3. Remove camel case (e.g. cAmelCAse => camelcAse => camelcase)
   • Find: ([a-z])([A-Z])
   • Replace: $1\l$2
4. Lowercase letters within words (e.g. LowerCASe => Lowercase)
   • Find: (\w)([A-Z]+)
   • Replace: $1\L$2
   • Alternate Replace: \L$0
5. Uppercase letters within words (e.g. upperCASe => uPPERCASE)
   • Find: (\w)([A-Z]+)
   • Replace: $1\U$2
6. Uppercase previous (e.g. upperCase => UPPERCase)
   • Find: (\w+)([A-Z])
   • Replace: \U$1$2
7. Lowercase previous (e.g. LOWERCase => lowerCase)
   • Find: (\w+)([A-Z])
   • Replace: \L$1$2
8. Uppercase the rest (e.g. upperCase => upperCASE)
   • Find: ([A-Z])(\w+)
   • Replace: $1\U$2
9. Lowercase the rest (e.g. lOWERCASE => lOwercase)
   • Find: ([A-Z])(\w+)
   • Replace: $1\L$2
10. Shift-right-uppercase (e.g. Case => cAse => caSe => casE)
    • Find: ([a-z\s])([A-Z])(\w)
    • Replace: $1\l$2\u$3
11. Shift-left-uppercase (e.g. CasE => CaSe => CAse => Case)
    • Find: (\w)([A-Z])([a-z\s])
    • Replace: \u$1\l$2$3

Regarding the question (match words with at least one uppercase and one lowercase letter and make them lowercase), leemour's comment-answer is the right answer. Just to clarify, if there is only one group to replace, you can just use ?: in the inner groups (i.e. non capture groups) or avoid creating them at all:

• Find: ((?:[a-z][A-Z]+)|(?:[A-Z]+[a-z])) OR ([a-z][A-Z]+|[A-Z]+[a-z])
• Replace: \L$1

2016-06-23 Edit

Tyler suggested by editing this answer an alternate find expression for #4:

• (\B)([A-Z]+)

According to the documentation, \B will look for a character that is not at the word's boundary (i.e. not at the beginning and not at the end). You can use the Replace All button and it does the exact same thing as if you had (\w)([A-Z]+) as the find expression.

However, the downside of \B is that it does not allow single replacements, perhaps due to the find's "not boundary" restriction (please do edit this if you know the exact reason).

SimpleDateFormat.format(...) takes a Date as parameter and format Date to String. So you need have a look API carefully

The native JavaScript approach -

('<strong>Look just ...</strong>').replace(/</g, '&lt;').replace(/>/g, '&gt;');

Enjoy!

Modifying the example here:

You can use legend_out = False

import seaborn as sns
sns.set(style="whitegrid")

titanic = sns.load_dataset("titanic")

g = sns.factorplot("class", "survived", "sex",
                    data=titanic, kind="bar",
                    size=6, palette="muted",
                   legend_out=False)
g.despine(left=True)
g.set_ylabels("survival probability")

The best way to set/get the value of a textarea is the .val(), .value method.

.text() internally uses the .textContent (or .innerText for IE) method to get the contents of a <textarea>. The following test cases illustrate how text() and .val() relate to each other:

var t = '<textarea>';
console.log($(t).text('test').val());             // Prints test
console.log($(t).val('too').text('test').val());  // Prints too
console.log($(t).val('too').text());              // Prints nothing
console.log($(t).text('test').val('too').val());  // Prints too

console.log($(t).text('test').val('too').text()); // Prints test

The value property, used by .val() always shows the current visible value, whereas text()'s return value can be wrong.

std::chrono::time_point<std::chrono::system_clock> now = std::chrono::system_clock::now();

This is a great place for auto:

auto now = std::chrono::system_clock::now();

Since you want to traffic at millisecond precision, it would be good to go ahead and covert to it in the time_point:

auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

now_ms is a time_point, based on system_clock, but with the precision of milliseconds instead of whatever precision your system_clock has.

auto epoch = now_ms.time_since_epoch();

epoch now has type std::chrono::milliseconds. And this next statement becomes essentially a no-op (simply makes a copy and does not make a conversion):

auto value = std::chrono::duration_cast<std::chrono::milliseconds>(epoch);

Here:

long duration = value.count();

In both your and my code, duration holds the number of milliseconds since the epoch of system_clock.

This:

std::chrono::duration<long> dur(duration);

Creates a duration represented with a long, and a precision of seconds. This effectively reinterpret_casts the milliseconds held in value to seconds. It is a logic error. The correct code would look like:

std::chrono::milliseconds dur(duration);

This line:

std::chrono::time_point<std::chrono::system_clock> dt(dur);

creates a time_point based on system_clock, with the capability of holding a precision to the system_clock's native precision (typically finer than milliseconds). However the run-time value will correctly reflect that an integral number of milliseconds are held (assuming my correction on the type of dur).

Even with the correction, this test will (nearly always) fail though:

if (dt != now)

Because dt holds an integral number of milliseconds, but now holds an integral number of ticks finer than a millisecond (e.g. microseconds or nanoseconds). Thus only on the rare chance that system_clock::now() returned an integral number of milliseconds would the test pass.

But you can instead:

if (dt != now_ms)

And you will now get your expected result reliably.

Putting it all together:

int main ()
{
    auto now = std::chrono::system_clock::now();
    auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    std::chrono::milliseconds dur(duration);

    std::chrono::time_point<std::chrono::system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Personally I find all the std::chrono overly verbose and so I would code it as:

int main ()
{
    using namespace std::chrono;
    auto now = system_clock::now();
    auto now_ms = time_point_cast<milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    milliseconds dur(duration);

    time_point<system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Which will reliably output:

Success.

Finally, I recommend eliminating temporaries to reduce the code converting between time_point and integral type to a minimum. These conversions are dangerous, and so the less code you write manipulating the bare integral type the better:

int main ()
{
    using namespace std::chrono;
    // Get current time with precision of milliseconds
    auto now = time_point_cast<milliseconds>(system_clock::now());
    // sys_milliseconds is type time_point<system_clock, milliseconds>
    using sys_milliseconds = decltype(now);
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    sys_milliseconds dt{milliseconds{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

The main danger above is not interpreting integral_duration as milliseconds on the way back to a time_point. One possible way to mitigate that risk is to write:

    sys_milliseconds dt{sys_milliseconds::duration{integral_duration}};

This reduces risk down to just making sure you use sys_milliseconds on the way out, and in the two places on the way back in.

And one more example: Let's say you want to convert to and from an integral which represents whatever duration system_clock supports (microseconds, 10^th of microseconds or nanoseconds). Then you don't have to worry about specifying milliseconds as above. The code simplifies to:

int main ()
{
    using namespace std::chrono;
    // Get current time with native precision
    auto now = system_clock::now();
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    system_clock::time_point dt{system_clock::duration{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

This works, but if you run half the conversion (out to integral) on one platform and the other half (in from integral) on another platform, you run the risk that system_clock::duration will have different precisions for the two conversions.

I have on several projects.

The biggest difference in my opinion

• jQuery UI is fallback safe, it works correctly and looks good in old browsers, where Bootstrap is based on CSS3 which basically means GREAT in new browsers, not so great in old

• Update frequency: Bootstrap is getting some great big updates with awesome new features, but sadly they might break previous code, so you can't just install bootstrap and update when there is a new major release, it basically requires a lot of new coding

• jQuery UI is based on good html structure with transformations from JavaScript, while Bootstrap is based on visually and customizable inline structure. (calling a widget in JQUERY UI, defining it in Bootstrap)

So what to choose?

That always depends on the type of project you are working on. Is cool and fast looking widgets better, or are your users often using old browsers?

I always end up using both, so I can use the best of both worlds.

Here are the links to both frameworks, if you decide to use them.

1. jQuery UI
2. Bootstrap

I had this situation before my solution was to override the pre_save() method of the target field class it will be called only if the field has been changed
useful with FileField example:

class PDFField(FileField):
    def pre_save(self, model_instance, add):
        # do some operations on your file 
        # if and only if you have changed the filefield

disadvantage:
not useful if you want to do any (post_save) operation like using the created object in some job (if certain field has changed)

Here's an example using an extension. This assumes the view has the same width and height.

Need to use a layout change listener to get the view size. Then you can just call this on a view like this myView.setRoundedBackground(Color.WHITE)

fun View.setRoundedBackground(@ColorInt color: Int) {
    addOnLayoutChangeListener(object: View.OnLayoutChangeListener {
        override fun onLayoutChange(v: View?, left: Int, top: Int, right: Int, bottom: Int, oldLeft: Int, oldTop: Int, oldRight: Int, oldBottom: Int) {

            val shape = GradientDrawable()
            shape.cornerRadius = measuredHeight / 2f
            shape.setColor(color)

            background = shape

            removeOnLayoutChangeListener(this)
        }
    })
}

When I've done this, rather than fiddling the original migration, I create a new one with just the add column in the up section and a drop column in the down section.

You can change the original and rerun it if you migrate down between, but in this case I think that's made a migration that won't work properly.

As currently posted, you're adding the column and then creating the table.

If you change the order it might work. Or, as you're modifying an existing migration, just add it to the create table instead of doing a separate add column.

Defining constants by using preprocessor directive #define is not recommended to apply not only in C++, but also in C. These constants will not have the type. Even in C was proposed to use const for constants.

Please try my profiler, called cRunWatch. It is just two files, so it is easy to integrate with your projects, and requires adding exactly one line to instrument a piece of code.

MySQL is pretty clear about its maximum row size:

Every table (regardless of storage engine) has a maximum row size of 65,535 bytes. Storage engines may place additional constraints on this limit, reducing the effective maximum row size.

. . .

Individual storage engines might impose additional restrictions that limit table column count. Examples:

InnoDB permits up to 1000 columns.

InnoDB restricts row size to something less than half a database page (approximately 8000 bytes), not including VARBINARY, VARCHAR, BLOB, or TEXT columns.

Different InnoDB storage formats (COMPRESSED, REDUNDANT) use different amounts of page header and trailer data, which affects the amount of storage available for rows.

If you have 325 repeating sets of columns, you are exceeding several of the restrictions. This is also a suspicious data format. You should have 325 rows for each row in the table you want, one for each group of columns.

Please create a custom TextView and use it :

public class CustomTextView extends TextView {

    public CapitalizedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        if (text.length() > 0) {
            text = String.valueOf(text.charAt(0)).toUpperCase() + text.subSequence(1, text.length());
        }
        super.setText(text, type);
    }
}

I know this is old. I just wanted to dump this here for anyone that was looking for an answer to getting a domain name. This is in coordination with Peter's answer. There "is" a bug as stated by Rich. But, you can always make a simple workaround for that. The way I can tell if they are still on the domain or not is by pinging the domain name. If it responds, continue on with whatever it was that I needed the domain for. If it fails, I drop out and go into "offline" mode. Simple string method.

 string GetDomainName()
    {
        string _domain = IPGlobalProperties.GetIPGlobalProperties().DomainName;

        Ping ping = new Ping();

        try
        {
            PingReply reply = ping.Send(_domain);

            if (reply.Status == IPStatus.Success)
            {
                return _domain;
            }
            else
            {
                return reply.Status.ToString();
            }
        }
        catch (PingException pExp)
        {
            if (pExp.InnerException.ToString() == "No such host is known")
            {
                return "Network not detected!";
            }

            return "Ping Exception";
        }
    }

    public ActionResult ActionName(string ReqParam1, string ReqParam2, string ReqParam3, string ReqParam4)
    {
        this.ControllerContext.HttpContext.Response.Headers.Add("Access-Control-Allow-Origin","*");
         /*
                --Your code goes here --
         */
        return Json(new { ReturnData= "Data to be returned", Success=true }, JsonRequestBehavior.AllowGet);
    }

You can parse the existing XML file into DOM and append new elements to the DOM. Very similar to what you did with creating brand new XML. I am assuming you do not have to worry about duplicate server. If you do have to worry about that, you will have to go through the elements in the DOM to check for duplicates.

DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();

/* parse existing file to DOM */
Document document = documentBuilder.parse(new File("exisgint/xml/file"));

Element root = document.getDocumentElement();

for (Server newServer : Collection<Server> bunchOfNewServers){
  Element server = Document.createElement("server");
  /* create and setup the server node...*/

 root.appendChild(server);
}

/* use whatever method to output DOM to XML (for example, using transformer like you did).*/

Another crazy possibility: If you follow a simple source control arrangement of putting Branch\Main, Main, and Release next to each other and you somehow end up adding an existing project from Main instead of Branch\Main (assuming your working solution is Branch\Main), you may see this error.

The solution is simple: reference the right project!

You can use overflow:auto;

You can also control the x or y axis individually with the overflow-x and overflow-y properties.

Example:

.content {overflow:auto;}
.content {overflow-y:auto;}
.content {overflow-x:auto;}

If you have a working copy then svn status will help.

svn status -u -v

The --show-updates (-u) option contacts the repository and adds information about things that are out of date.

I was looking into this but wanted to have a different transition rate for in and out.

This is what I ended up doing:

//css
.addedClass {
    background: #5eb4fc;
}

// js
function setParentTransition(id, prop, delay, style, callback) {
    $(id).css({'-webkit-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'-moz-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'-o-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'transition' : prop + ' ' + delay + ' ' + style});
    callback();
}
setParentTransition(id, 'background', '0s', 'ease', function() {
    $('#elementID').addClass('addedClass');
});

setTimeout(function() {
    setParentTransition(id, 'background', '2s', 'ease', function() {
        $('#elementID').removeClass('addedClass');
    });
});

This instantly turns the background color to #5eb4fc and then slowly fades back to normal over 2 seconds.

Here's a fiddle

Yes, REM and PX are relative yet other answers have suggested to go for REM over PX, I would also like to back this up using an accessibility example.
When user sets different font-size on browser, REM automatically scale up and down elements like fonts, images etc on the webpage which is not the case with PX.

In the below gif left side text is set using font size REM unit while right side font is set by PX unit.

As you can see that REM is scaling up/down automatically when I resize the default font-size of webpage.(bottom-right side)

Default font-size of a webpage is 16px which is equal to 1 rem (only for default html page i.e. html{font-size:100%}), so, 1.25rem is equal to 20px.

P.S: who else is using REM? CSS Frameworks! like Bootstrap 4, Bulma CSS etc, so better get along with it.

Here's a method using display:flex:

  position: fixed;_x000D_
  align-items: center;_x000D_

Check Browser Compatability

A new paper has been released with several tests against reCAPTCHA:

https://www.blackhat.com/docs/asia-16/materials/asia-16-Sivakorn-Im-Not-a-Human-Breaking-the-Google-reCAPTCHA-wp.pdf

Some highlights:

• By keeping a cookie active for +9 days (by browsing sites with Google resources), you can then pass reCAPTCHA by only clicking the checkbox;
• There are no restrictions based on requests per IP;
• The browser's user agent must be real, and Google run tests against your environment to ensure it matches the user agent;
• Google tests if the browser can render a Canvas;
• Screen resolution and mouse events don't affect the results;

Google has already fixed the cookie vulnerability and is probably restricting some behaviors based on IPs.

Another interesting finding is that Google runs a VM in JavaScript that obfuscates much of reCAPTCHA code and behavior. This VM is known as botguard and is used to protect other services besides reCAPTCHA:

https://github.com/neuroradiology/InsideReCaptcha

UPDATE 2017

A recent paper (from August) was published on WOOT 2017 achieving 85% accuracy in solving noCAPTCHA reCAPTCHA audio challenges:

http://uncaptcha.cs.umd.edu/papers/uncaptcha_woot17.pdf

UPDATE 2018

Google is introducing reCAPTCHA v3, which looks like a "human score prediction engine" that is calibrated per website. It can be installed into different pages of a website (working like a Google Analytics script) to help reCAPTCHA and the website owner to understand the behaviour of humans vs. bots before filling a reCAPTCHA.

For those using an ImageButton here is how you do it:

In style.xml:

<style name="BlueImageButton" parent="Base.Widget.AppCompat.ImageButton">
    <item name="colorButtonNormal">@color/primary</item>
    <item name="android:tint">@color/white</item>
</style>

in v21/style.xml:

<style name="BlueImageButton" parent="Widget.AppCompat.ImageButton">
    <item name="android:colorButtonNormal">@color/primary</item>
    <item name="android:tint">@color/white</item>
</style>

Then in your layout file:

<android.support.v7.widget.AppCompatImageButton
    android:id="@+id/my_button"
    android:theme="@style/BlueImageButton"
    android:layout_width="42dp"
    android:layout_height="42dp"
    android:layout_gravity="center_vertical"
    android:src="@drawable/ic_check_black_24dp"
    />

SELECT ..., CONCAT( 'category_id=', tableOne.category_id) as query2  FROM tableOne 
LEFT JOIN tableTwo
ON tableTwo.query = query2

You could make use of Prepared Stements like this.

set @query = concat( "select name from " );
set @query = concat( "table_name"," [where condition] " );

prepare stmt from @like_q;
execute stmt;

A function call needs to be performed with objects. You are doing the equivalent of this:

// function declaration/definition
void foo(int) {}

// function call
foo(int); // wat!??

i.e. passing a type where an object is required. This makes no sense in C or C++. You need to be doing

int i = 42;
foo(i);

or

foo(42);

What you are (trying to do)/doing in your snippet is to return a local variable from the function, which is not at all recommended - nor is it allowed according to the standard.

If you'd like to create a int[6][6] from your function you'll either have to allocate memory for it on the free-store (ie. using new T/malloc or similar function), or pass in an already allocated piece of memory to MakeGridOfCounts.

One caveat, though. Note that np.array(None).size returns 1! This is because a.size is equivalent to np.prod(a.shape), np.array(None).shape is (), and an empty product is 1.

>>> import numpy as np
>>> np.array(None).size
1
>>> np.array(None).shape
()
>>> np.prod(())
1.0

Therefore, I use the following to test if a numpy array has elements:

>>> def elements(array):
    ...     return array.ndim and array.size

>>> elements(np.array(None))
0
>>> elements(np.array([]))
0
>>> elements(np.zeros((2,3,4)))
24

I highly recommend reading the docs on the Intent.FLAG_ACTIVITY_CLEAR_TOP flag. Using it will not necessarily go back all the way to the first (main) activity. The flag will only remove all existing activities up to the activity class given in the Intent. This is explained well in the docs:

For example, consider a task consisting of the activities: A, B, C, D.
If D calls startActivity() with an Intent that resolves to the component of
activity B, then C and D will be finished and B receive the given Intent, 
resulting in the stack now being: A, B.

Note that the activity can set to be moved to the foreground (i.e., clearing all other activities on top of it), and then also being relaunched, or only get onNewIntent() method called.

For IE 6, you'll want to equal colspan to the number of columns in your table. If you have 5 columns, then you'll want: colspan="5".

The reason is that IE handles colspans differently, it uses the HTML 3.2 specification:

IE implements the HTML 3.2 definition, it sets colspan=0 as colspan=1.

The bug is well documented.

}

Returning &iterator will return the address of the iterator. If you want to return a way of referring to the element return the iterator itself.

Beware that you do not need the vector to be a global in order to return the iterator/pointer, but that operations in the vector can invalidate the iterator. Adding elements to the vector, for example, can move the vector elements to a different position if the new size() is greater than the reserved memory. Deletion of an element before the given item from the vector will make the iterator refer to a different element.

In both cases, depending on the STL implementation it can be hard to debug with just random errors happening each so often.

EDIT after comment: 'yes, I didn't want to return the iterator a) because its const, and b) surely it is only a local, temporary iterator? – Krakkos'

Iterators are not more or less local or temporary than any other variable and they are copyable. You can return it and the compiler will make the copy for you as it will with the pointer.

Now with the const-ness. If the caller wants to perform modifications through the returned element (whether pointer or iterator) then you should use a non-const iterator. (Just remove the 'const_' from the definition of the iterator).

You can use the viewport height, just set the height of your div to height:100vh;, this will set the height of your div to the height of the viewport of the device, furthermore, if you want it to be exactly as your device screen, set the margin and padding to 0.

Plus, It will be a good idea to set the viewport meta tag:

<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1.0" />

Please Note that this is relatively new and is not supported in IE8-, take a look at the support list before considering this approach (http://caniuse.com/#search=viewport).

Hope this helps.

timeout = int(seconds)

Since requests >= 2.4.0, you can use the timeout argument, i.e:

requests.get('https://duckduckgo.com/', timeout=10)

Note:

timeout is not a time limit on the entire response download; rather, an exception is raised if the server has not issued a response for timeout seconds ( more precisely, if no bytes have been received on the underlying socket for timeout seconds). If no timeout is specified explicitly, requests do not time out.

Using Google as the SSL proxy is not working currently,

Why?

If you opened any page from google, you will find there is a x-frame-options field in the header.

The X-Frame-Options HTTP response header can be used to indicate whether or not a browser should be allowed to render a page in a <frame>, <iframe> or <object>. Sites can use this to avoid clickjacking attacks, by ensuring that their content is not embedded into other sites.

(Quote from MDN)

One of the solution

Below is my work around for this problem:

Upload the content to AWS S3, and it will create a https link for the resource.
Notice: set the permission to the html file for allowing everyone view it.

After that, we can using it as the src of iframe in the https websites.

If you are drawing on the Graphics of the Control than you should do something draw on the Bitmap everything you are drawing on the canvas, but have in mind that Bitmap needs to be the exact size of the control you are drawing on:

  Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width,myControl.ClientRectangle.Height);
  Graphics gBmp = Graphics.FromImage(bmp);
  gBmp.DrawEverything(); //this is your code for drawing
  gBmp.Dispose();
  bmp.Save("image.png", ImageFormat.Png);

Or you can use a DrawToBitmap method of the Control. Something like this:

Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width, myControl.ClientRectangle.Height);
myControl.DrawToBitmap(bmp,new Rectangle(0,0,bmp.Width,bmp.Height));
bmp.Save("image.png", ImageFormat.Png);

First check whether the java classes are compiled or not in your [PROJECT_NAME]\target\classes directory.

If not you have some compilation errors in your java classes.

Had the same problem. I was passing a non-const reference of custom class and the constructor complained (some tuple template errors). Replaced the reference with pointer and it worked.

I didn't have an issue with this until I tried to use the Location Services, at which point I had to put the apply plugin: 'com.google.gms.google-services' at the bottom of the file, rather than the top. The reason being that when you have it at the top there are collision issues, and by placing it at the bottom, you avoid those issue.

If you want to refer to a nested table by multiple keys you can just assign them to separate keys. The tables are not duplicated, and still reference the same values.

arr = {}
apples = {'a', "red", 5 }
arr.apples = apples
arr[1] = apples

This code block lets you iterate through all the key-value pairs in a table (http://lua-users.org/wiki/TablesTutorial):

for k,v in pairs(t) do
 print(k,v)
end

I recommend setting the display options inside a context manager so that it only affects a single output. I usually prefer "pretty" html-output, and define a function force_show_all(df) for displaying the DataFrame df:

from IPython.core.display import display, HTML

def force_show_all(df):
    with pd.option_context('display.max_rows', None, 'display.max_columns', None, 'display.width', None):
        display(HTML(df.to_html()))

# ... now when you're ready to fully display df:
force_show_all(df)

As others have mentioned, please be cautious to only call this on a reasonably-sized dataframe.

you can save the model and load in this way.

from keras.models import Sequential, load_model
from keras_contrib.losses import import crf_loss
from keras_contrib.metrics import crf_viterbi_accuracy

# To save model
model.save('my_model_01.hdf5')

# To load the model
custom_objects={'CRF': CRF,'crf_loss':crf_loss,'crf_viterbi_accuracy':crf_viterbi_accuracy}

# To load a persisted model that uses the CRF layer 
model1 = load_model("/home/abc/my_model_01.hdf5", custom_objects = custom_objects)

Here's a practical reason to prefer functions over stored procedures. If you have a stored procedure that needs the results of another stored procedure, you have to use an insert-exec statement. This means that you have to create a temp table and use an exec statement to insert the results of the stored procedure into the temp table. It's messy. One problem with this is that insert-execs cannot be nested.

If you're stuck with stored procedures that call other stored procedures, you may run into this. If the nested stored procedure simply returns a dataset, it can be replaced with a table-valued function and you'll no longer get this error.

(this is yet another reason we should keep business logic out of the database)

I'm super late to the party, but this doesn't appear in any of the existing answers:

GROUP BY DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', date_column) / 10 * 10, '2000')

• The 10 and MINUTE terms can be changed to any number and DATEPART, respectively.
• It is a DATETIME value, which means:
  • It works fine across long time intervals. (There is no collision between years.)
  • Including it in the SELECT statement will give your output a column with pretty output truncated at the level you specify.
• '2000' is an "anchor date" around which SQL will perform the date math. Jereonh discovered below that you encounter an integer overflow with the previous anchor (0) when you group recent dates by seconds or milliseconds.^†

SELECT   DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', aa.[date]) / 10 * 10, '2000')
                                                               AS [date_truncated],
         COUNT(*) AS [records_in_interval],
         AVG(aa.[value]) AS [average_value]
FROM     [friib].[dbo].[archive_analog] AS aa
GROUP BY DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', aa.[date]) / 10 * 10, '2000')
ORDER BY [date_truncated]

If your data spans centuries,^‡ using a single anchor date for second- or millisecond grouping will still encounter the overflow. If that is happening, you can ask each row to anchor the binning comparison to its own date's midnight:

• Use DATEADD(DAY, DATEDIFF(DAY, 0, aa.[date]), 0) instead of '2000' wherever it appears above. Your query will be totally unreadable, but it will work.

• An alternative might be CONVERT(DATETIME, CONVERT(DATE, aa.[date])) as the replacement.

_{^† 2³² ˜ 4.29E+9, so if your DATEPART is SECOND, you get 4.3 billion seconds on either side, or "anchor ± 136 years." Similarly, 2³² milliseconds is ˜ 49.7 days.
^‡ If your data actually spans centuries or millenia and is still accurate to the second or millisecond… congratulations! Whatever you're doing, keep doing it.}

As of HttpComponents 4.2+ there is a new class URIBuilder, which provides convenient way for generating URIs.

You can use either create URI directly from String URL:

List<NameValuePair> listOfParameters = ...;

URI uri = new URIBuilder("http://example.com:8080/path/to/resource?mandatoryParam=someValue")
    .addParameter("firstParam", firstVal)
    .addParameter("secondParam", secondVal)
    .addParameters(listOfParameters)
    .build();

Otherwise, you can specify all parameters explicitly:

URI uri = new URIBuilder()
    .setScheme("http")
    .setHost("example.com")
    .setPort(8080)
    .setPath("/path/to/resource")
    .addParameter("mandatoryParam", "someValue")
    .addParameter("firstParam", firstVal)
    .addParameter("secondParam", secondVal)
    .addParameters(listOfParameters)
    .build();

Once you have created URI object, then you just simply need to create HttpGet object and perform it:

//create GET request
HttpGet httpGet = new HttpGet(uri);
//perform request
httpClient.execute(httpGet ...//additional parameters, handle response etc.

You should style for ::-ms-clear (http://msdn.microsoft.com/en-us/library/windows/apps/hh465740.aspx):

::-ms-clear {
   display: none;
}

And you also style for ::-ms-reveal pseudo-element for password field:

::-ms-reveal {
   display: none;
}

$('div[id ^= "player_"]');

This worked for me..select all Div starts with "players_" keyword and display it.

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

Also See
How to Use Buttons

import java.lang.String; //contains equalsIgnoreCase()
/*
*
*/
String s1 = "Hello";
String s2 = "hello";

if (s1.equalsIgnoreCase(s2)) {
System.out.println("hai");
} else {
System.out.println("welcome");
}

Now it will output : hai

The @EJB is used to inject EJB's only and is available for quite some time now. @Inject can inject any managed bean and is a part of the new CDI specification (since Java EE 6).

In simple cases you can simply change @EJB to @Inject. In more advanced cases (e.g. when you heavily depend on @EJB's attributes like beanName, lookup or beanInterface) than in order to use @Inject you would need to define a @Producer field or method.

These resources might be helpful to understand the differences between @EJB and @Produces and how to get the best of them:

Antonio Goncalves' blog:
CDI Part I
CDI Part II
CDI Part III

JBoss Weld documentation:
CDI and the Java EE ecosystem

StackOverflow:
Inject @EJB bean based on conditions

Great! The solution given above worked for me. Had the same problem with a GET call.

 method: 'GET',
 data: '',
 headers: {
        "Content-Type": "application/json"
 }

You need to add

#container
{
    display:inline-block;
    position:relative;
    background:rgb(255,100,0);
    margin:0px;
    width:40%;
    height:100px;
    margin-right:-4px;
}

because whenever you write display:inline-block it takes an additional margin-right:4px. So, you need to remove it.

Intent intent = new Intent(LoginActivity.this, Home.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);  //It is use to finish current activity
startActivity(intent);
this.finish();

This clearly is a bad case of controller logic in a view. It would be better to do this in a controller and return the desired view.

[ChildActionOnly]
public ActionResult Results() 
{
    EnumerableRowCollection<DataRow> custs = ViewBag.Customers;
    bool anyRows = custs.Any();

    if(anyRows == false)
    {
        return View("NoResults");
    }
    else
    {
        return View("OtherView");
    }
}

Modify NoResults.cshtml to a Partial.

And call this as a Partial view in the parent view

@Html.Partial("Results")

You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3

The ChildActionOnly attribute will make sure you cannot go to this page by navigating and that this view must be rendered as a partial, thus by a parent view. cfr: Using ChildActionOnly in MVC

You can also take a look at PDFMiner (or for older versions of Python see PDFMiner and PDFMiner).

A particular feature of interest in PDFMiner is that you can control how it regroups text parts when extracting them. You do this by specifying the space between lines, words, characters, etc. So, maybe by tweaking this you can achieve what you want (that depends of the variability of your documents). PDFMiner can also give you the location of the text in the page, it can extract data by Object ID and other stuff. So dig in PDFMiner and be creative!

But your problem is really not an easy one to solve because, in a PDF, the text is not continuous, but made from a lot of small groups of characters positioned absolutely in the page. The focus of PDF is to keep the layout intact. It's not content oriented but presentation oriented.

My job recently tasked me with logging all the tracebacks/exceptions from our application. I tried numerous techniques that others had posted online such as the one above but settled on a different approach. Overriding traceback.print_exception.

I have a write up at http://www.bbarrows.com/ That would be much easier to read but Ill paste it in here as well.

When tasked with logging all the exceptions that our software might encounter in the wild I tried a number of different techniques to log our python exception tracebacks. At first I thought that the python system exception hook, sys.excepthook would be the perfect place to insert the logging code. I was trying something similar to:

import traceback
import StringIO
import logging
import os, sys

def my_excepthook(excType, excValue, traceback, logger=logger):
    logger.error("Logging an uncaught exception",
                 exc_info=(excType, excValue, traceback))

sys.excepthook = my_excepthook  

This worked for the main thread but I soon found that the my sys.excepthook would not exist across any new threads my process started. This is a huge issue because most everything happens in threads in this project.

After googling and reading plenty of documentation the most helpful information I found was from the Python Issue tracker.

The first post on the thread shows a working example of the sys.excepthook NOT persisting across threads (as shown below). Apparently this is expected behavior.

import sys, threading

def log_exception(*args):
    print 'got exception %s' % (args,)
sys.excepthook = log_exception

def foo():
    a = 1 / 0

threading.Thread(target=foo).start()

The messages on this Python Issue thread really result in 2 suggested hacks. Either subclass Thread and wrap the run method in our own try except block in order to catch and log exceptions or monkey patch threading.Thread.run to run in your own try except block and log the exceptions.

The first method of subclassing Thread seems to me to be less elegant in your code as you would have to import and use your custom Thread class EVERYWHERE you wanted to have a logging thread. This ended up being a hassle because I had to search our entire code base and replace all normal Threads with this custom Thread. However, it was clear as to what this Thread was doing and would be easier for someone to diagnose and debug if something went wrong with the custom logging code. A custome logging thread might look like this:

class TracebackLoggingThread(threading.Thread):
    def run(self):
        try:
            super(TracebackLoggingThread, self).run()
        except (KeyboardInterrupt, SystemExit):
            raise
        except Exception, e:
            logger = logging.getLogger('')
            logger.exception("Logging an uncaught exception")

The second method of monkey patching threading.Thread.run is nice because I could just run it once right after __main__ and instrument my logging code in all exceptions. Monkey patching can be annoying to debug though as it changes the expected functionality of something. The suggested patch from the Python Issue tracker was:

def installThreadExcepthook():
    """
    Workaround for sys.excepthook thread bug
    From
http://spyced.blogspot.com/2007/06/workaround-for-sysexcepthook-bug.html

(https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1230540&group_id=5470).
    Call once from __main__ before creating any threads.
    If using psyco, call psyco.cannotcompile(threading.Thread.run)
    since this replaces a new-style class method.
    """
    init_old = threading.Thread.__init__
    def init(self, *args, **kwargs):
        init_old(self, *args, **kwargs)
        run_old = self.run
        def run_with_except_hook(*args, **kw):
            try:
                run_old(*args, **kw)
            except (KeyboardInterrupt, SystemExit):
                raise
            except:
                sys.excepthook(*sys.exc_info())
        self.run = run_with_except_hook
    threading.Thread.__init__ = init

It was not until I started testing my exception logging I realized that I was going about it all wrong.

To test I had placed a

raise Exception("Test")

somewhere in my code. However, wrapping a a method that called this method was a try except block that printed out the traceback and swallowed the exception. This was very frustrating because I saw the traceback bring printed to STDOUT but not being logged. It was I then decided that a much easier method of logging the tracebacks was just to monkey patch the method that all python code uses to print the tracebacks themselves, traceback.print_exception. I ended up with something similar to the following:

def add_custom_print_exception():
    old_print_exception = traceback.print_exception
    def custom_print_exception(etype, value, tb, limit=None, file=None):
        tb_output = StringIO.StringIO()
        traceback.print_tb(tb, limit, tb_output)
        logger = logging.getLogger('customLogger')
        logger.error(tb_output.getvalue())
        tb_output.close()
        old_print_exception(etype, value, tb, limit=None, file=None)
    traceback.print_exception = custom_print_exception

This code writes the traceback to a String Buffer and logs it to logging ERROR. I have a custom logging handler set up the 'customLogger' logger which takes the ERROR level logs and send them home for analysis.

The identity section goes under the system.web section, not under authentication:

<system.web>
  <authentication mode="Windows"/>
  <identity impersonate="true" userName="foo" password="bar"/>
</system.web>

I tried to avoid too much custom CSS and after reading some other examples I merged the ideas there and got this solution:

<div class="form-group has-feedback has-clear">
    <input type="text" class="form-control" ng-model="ctrl.searchService.searchTerm" ng-change="ctrl.search()" placeholder="Suche"/>
    <a class="glyphicon glyphicon-remove-sign form-control-feedback form-control-clear" ng-click="ctrl.clearSearch()" style="pointer-events: auto; text-decoration: none;cursor: pointer;"></a>
</div>

As I don't use bootstrap's JavaScript, just the CSS together with Angular, I don't need the classes has-clear and form-control-clear, and I implemented the clear function in my AngularJS controller. With bootstrap's JavaScript this might be possible without own JavaScript.

Given that you're only converting to ints to then perform a comparison, I'd just switch the table definition around to using varchar also:

Create table #myTempTable
(
num varchar(12)
)
insert into #myTempTable (num) values (1),(2),(3),(4),(5)

and remove all of the attempted CONVERTs from the rest of the query.

 SELECT a.name, a.value AS value, COUNT(*) AS pocet   
 FROM 
 (SELECT item.name, value.value 
  FROM mdl_feedback AS feedback 
  INNER JOIN mdl_feedback_item AS item 
       ON feedback.id = item.feedback
  INNER JOIN mdl_feedback_value AS value 
       ON item.id = value.item 
   WHERE item.typ = 'multichoicerated' AND item.feedback IN (43)
 ) AS a 
 INNER JOIN #myTempTable 
     on a.value = #myTempTable.num
 GROUP BY a.name, a.value ORDER BY a.name

Just as a side note, <button> will implicitly submit, which can cause problems if you want to use a button in a form without it submitting. Thus, another reason to use <input type="button"> (or <button type="button">)

Edit - more details

Without a type, button implicitly receives type of submit. It does not matter how many submit buttons or inputs there are in the form, any one of them which is explicitly or implicitly typed as submit, when clicked, will submit the form.

There are 3 supported types for a button

submit ||  "submits the form when clicked (default)"
reset  ||  "resets the fields in the form when clicked"
button ||  "clickable, but without any event handler until one is assigned"

Here's an example where the absence of b would throw a TypeError exception in Python 3.x

>>> f=open("new", "wb")
>>> f.write("Hello Python!")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' does not support the buffer interface

Adding a b prefix would fix the problem.

Definitely in Modules.

• Sheets can be deleted, copied and moved with surprising results.
• You can't call code in sheet "code-behind" from other modules without fully qualifying the reference. This will lead to coupling of the sheet and the code in other modules/sheets.
• Modules can be exported and imported into other workbooks, and put under version control
• Code in split logically into modules (data access, utilities, spreadsheet formatting etc.) can be reused as units, and are easier to manage if your macros get large.

Since the tooling is so poor in primitive systems such as Excel VBA, best practices, obsessive code hygiene and religious following of conventions are important, especially if you're trying to do anything remotely complex with it.

This article explains the intended usages of different types of code containers. It doesn't qualify why these distinctions should be made, but I believe most developers trying to develop serious applications on the Excel platform follow them.

There's also a list of VBA coding conventions I've found helpful, although they're not directly related to Excel VBA. Please ignore the crazy naming conventions they have on that site, it's all crazy hungarian.

@echo off 
Net session >nul 2>&1 || (PowerShell start -verb runas '%~0' &exit /b)
Echo Administrative privileges have been got. & pause

The above works on my Windows 10 Version 1903

You want:

if (document.getElementById('customx').value === ""){
    //do something
}

The value property will give you a string value and you need to compare that against an empty string.

You can always encrypt data on the client side. Please note that not all of the data have to be encrypted because it has a performance issue.

Yep, using the staticmethod decorator

class MyClass(object):
    @staticmethod
    def the_static_method(x):
        print(x)

MyClass.the_static_method(2)  # outputs 2

Note that some code might use the old method of defining a static method, using staticmethod as a function rather than a decorator. This should only be used if you have to support ancient versions of Python (2.2 and 2.3)

class MyClass(object):
    def the_static_method(x):
        print(x)
    the_static_method = staticmethod(the_static_method)

MyClass.the_static_method(2)  # outputs 2

This is entirely identical to the first example (using @staticmethod), just not using the nice decorator syntax

Finally, use staticmethod sparingly! There are very few situations where static-methods are necessary in Python, and I've seen them used many times where a separate "top-level" function would have been clearer.

The following is verbatim from the documentation::

A static method does not receive an implicit first argument. To declare a static method, use this idiom:

class C:
    @staticmethod
    def f(arg1, arg2, ...): ...

The @staticmethod form is a function decorator – see the description of function definitions in Function definitions for details.

It can be called either on the class (such as C.f()) or on an instance (such as C().f()). The instance is ignored except for its class.

Static methods in Python are similar to those found in Java or C++. For a more advanced concept, see classmethod().

For more information on static methods, consult the documentation on the standard type hierarchy in The standard type hierarchy.

New in version 2.2.

Changed in version 2.4: Function decorator syntax added.

clip-path

.hide {
  clip-path: polygon(0px 0px,0px 0px,0px 0px,0px 0px);

To show use any of the following: opacity: 1; visibility: visible; display: block;

Another simple PHP example of using cURL:

<?php
    $ch = curl_init();                    // Initiate cURL
    $url = "http://www.somesite.com/curl_example.php"; // Where you want to post data
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST, true);  // Tell cURL you want to post something
    curl_setopt($ch, CURLOPT_POSTFIELDS, "var1=value1&var2=value2&var_n=value_n"); // Define what you want to post
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the output in string format
    $output = curl_exec ($ch); // Execute

    curl_close ($ch); // Close cURL handle

    var_dump($output); // Show output
?>

Example found here: http://devzone.co.in/post-data-using-curl-in-php-a-simple-example/

Instead of using curl_setopt you can use curl_setopt_array.

Try

loadUrl(String url, Map<String, String> extraHeaders)

For adding headers to resources loading requests, make custom WebViewClient and override:

API 24+:
WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request)
or
WebResourceResponse shouldInterceptRequest(WebView view, String url)

Now in eclipse Neon this feature is present. No need of any special settings or configuation .On Ctrl+Space the code suggestion is available

I'm very surprised to see that no-one has suggested using local broadcasts for DialogFragment to Activity communication! I find it to be so much simpler and cleaner than other suggestions. Essentially, you register for your Activity to listen out for the broadcasts and you send the local broadcasts from your DialogFragment instances. Simple. For a step-by-step guide on how to set it all up, see here.

Trying to find a good solution for this now, I happened upon the FeedEk jQuery RSS/ATOM Feed Plugin that does a great job of parsing and displaying RSS and Atom feeds via the jQuery Feed API. For a basic XML-based RSS feed, I've found it works like a charm and needs no server-side scripts or other CORS workarounds for it to run even locally.

This can be done in a single line, as long as the worksheet is active:

ActiveSheet.Visible = xlSheetHidden

However, you may not want to do this, especially if you use any "select" operations or you use any more ActiveSheet operations.

As the statement executed is not actually DML (eg UPDATE, INSERT or EXECUTE), but a piece of T-SQL which contains DML, I suspect it is not treated as an update-query.

Section 13.1.2.3 of the JDBC 4.1 specification states something (rather hard to interpret btw):

When the method execute returns true, the method getResultSet is called to retrieve the ResultSet object. When execute returns false, the method getUpdateCount returns an int. If this number is greater than or equal to zero, it indicates the update count returned by the statement. If it is -1, it indicates that there are no more results.

Given this information, I guess that executeUpdate() internally does an execute(), and then - as execute() will return false - it will return the value of getUpdateCount(), which in this case - in accordance with the JDBC spec - will return -1.

This is further corroborated by the fact 1) that the Javadoc for Statement.executeUpdate() says:

Returns: either (1) the row count for SQL Data Manipulation Language (DML) statements or (2) 0 for SQL statements that return nothing

And 2) that the Javadoc for Statement.getUpdateCount() specifies:

the current result as an update count; -1 if the current result is a ResultSet object or there are no more results

Just to clarify: given the Javadoc for executeUpdate() the behavior is probably wrong, but it can be explained.

Also as I commented elsewhere, the -1 might just indicate: maybe something was changed, but we simply don't know, or we can't give an accurate number of changes (eg because in this example it is a piece of T-SQL that is executed).

I used a local distribution of gradle downloaded from gradle website and used it in android studio.

It fixed the gradle build error.

Post::where('id',3)->update(['title'=>'Updated title']);

I had to render formulas using MathJax after ng-repeat ends, none of the above answers solved my problem, so I made like below. It's not a nice solution, but worked for me...

<div ng-repeat="formula in controller.formulas">
    <div>{{formula.string}}</div>
    {{$last ? controller.render_formulas() : ""}}
</div>

A shorter version of the accepted answer using Guava:

.getMap(Iterables.toArray(locations, WorldLocation.class));

can be shortened further by statically importing toArray:

import static com.google.common.collect.toArray;
// ...

    .getMap(toArray(locations, WorldLocation.class));

In case you came to this question but related to newer Angular version >= 2.0.

<div [id]="element.id"></div>

After you install Oracle Client components on the remote server, restart SQL Server Agent from the PC Management Console or directly from Sql Server Management Studio. This will allow the service to load correctly the path to the Oracle components. Otherwise your package will work on design time but fail on run time.

1 ) Go to view menu.
2 ) Select the DBMS_OUTPUT menu item.
3 ) Press Ctrl + N and select connection editor.
4 ) Execute the SET SERVEROUTPUT ON Command.
5 ) Then execute your PL/SQL Script.

I was searching for a simple solution without window focus. Jayk's answer, pynput, works perfect for me. Here is the example how I use it.

from pynput import keyboard

def on_press(key):
    if key == keyboard.Key.esc:
        return False  # stop listener
    try:
        k = key.char  # single-char keys
    except:
        k = key.name  # other keys
    if k in ['1', '2', 'left', 'right']:  # keys of interest
        # self.keys.append(k)  # store it in global-like variable
        print('Key pressed: ' + k)
        return False  # stop listener; remove this if want more keys

listener = keyboard.Listener(on_press=on_press)
listener.start()  # start to listen on a separate thread
listener.join()  # remove if main thread is polling self.keys

When your Android stuio/jre uses a differ version of java, you will receive this error. to solve it, just set Android studio/jre to your JAVA_HOME. and uninstall your own java.

How about:

  <tr ng-repeat="(key, value) in data">
    <td> {{key}} </td> <td> {{ value }} </td>
  </tr>
</table>

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.

To answer your specific questions:

• See this question on how to increase the stack size.
• You can limit the stack growth by:
  • grouping many local variables in an object: that object will be stored in the heap and only the reference is stored on the stack
  • limit the number of nested function calls (typically by not using recursion)
• For windows, the default stack size is 320k for 32bit and 1024k for 64bit, see this link.

here is another way to do this

if(!Yii::$app->request->getIsPost()) {
    return Yii::$app->getResponse()->redirect(array('/user/index',302));
}

In config/database.php I changed the default DB connection from mysql to sqlite. I deleted the .env file (actually renamed it) and created the sqlite file with touch storage/database.sqlite. The migration worked with sqlite.

Then I switched back the config/database.php default DB connection to mysql and recovered the .env file. The migration worked with mysql.

It doesn't make sense I guess. Maybe was something serverside.

Apparently, gcc doesn't behave like the one described in The C Programming language, where it says that the command cc helloworld.c produces a file called a.out which can be run by typing a.out on the prompt.

A Unix hasn't behaved in that way by default (so you can just write the executable name without ./ at the front) in a long time. It's called a.exe, because else Windows won't execute it, as it gets file types from the extension.

The ng-if directive, like other directives creates a child scope. See the script below (or this jsfiddle)

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular.min.js"></script>_x000D_
_x000D_
<script>_x000D_
    function main($scope) {_x000D_
        $scope.testa = false;_x000D_
        $scope.testb = false;_x000D_
        $scope.testc = false;_x000D_
        $scope.obj = {test: false};_x000D_
    }_x000D_
</script>_x000D_
_x000D_
<div ng-app >_x000D_
    <div ng-controller="main">_x000D_
        _x000D_
        Test A: {{testa}}<br />_x000D_
        Test B: {{testb}}<br />_x000D_
        Test C: {{testc}}<br />_x000D_
        {{obj.test}}_x000D_
        _x000D_
        <div>_x000D_
            testa (without ng-if): <input type="checkbox" ng-model="testa" />_x000D_
        </div>_x000D_
        <div ng-if="!testa">_x000D_
            testb (with ng-if): <input type="checkbox" ng-model="testb" /> {{testb}}_x000D_
        </div>_x000D_
        <div ng-if="!someothervar">_x000D_
            testc (with ng-if): <input type="checkbox" ng-model="testc" />_x000D_
        </div>_x000D_
        <div ng-if="!someothervar">_x000D_
            object (with ng-if): <input type="checkbox" ng-model="obj.test" />_x000D_
        </div>_x000D_
        _x000D_
    </div>_x000D_
</div>

So, your checkbox changes the testb inside of the child scope, but not the outer parent scope.

Note, that if you want to modify the data in the parent scope, you'll need to modify the internal properties of an object like in the last div that I added.

'origin/master' which can not be resolved as commit

Strange: you need to check your remotes:

git remote -v

And make sure origin is fetched:

git fetch origin

Then:

git branch -avv

(to see if you do have fetched an origin/master branch)

Finally, use git switch instead of the confusing git checkout, with Git 2.23+ (August 2019).

git switch -c test --track origin/master

After reading around alot, only this worked: In class to set Shared preferences:

 SharedPreferences userDetails = getApplicationContext().getSharedPreferences("test", MODE_PRIVATE);
                    SharedPreferences.Editor edit = userDetails.edit();
                    edit.clear();
                    edit.putString("test1", "1");
                    edit.putString("test2", "2");
                    edit.commit();

In AlarmReciever:

SharedPreferences userDetails = context.getSharedPreferences("test", Context.MODE_PRIVATE);
    String test1 = userDetails.getString("test1", "");
    String test2 = userDetails.getString("test2", "");

Something like this..

 RelativeLayout linearLayout = (RelativeLayout) findViewById(R.id.widget43);
                // ListView listView = (ListView) findViewById(R.id.ListView01);

                LayoutInflater inflater = (LayoutInflater) this
                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                // View footer = inflater.inflate(R.layout.footer, null);
                View footer = LayoutInflater.from(this).inflate(R.layout.footer,
                        null);
                final RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
                        RelativeLayout.LayoutParams.FILL_PARENT,
                        RelativeLayout.LayoutParams.FILL_PARENT);
                layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 1);
footer.setLayoutParams(layoutParams);

My manifest does not reference any themes... it should not have to AFAIK

Sure it does. Nothing is going to magically apply Theme.Styled to an activity. You need to declare your activities -- or your whole application -- is using Theme.Styled, e.g., :

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/Theme.Styled">

The ? is to allow Parameterized Query. These parameterized query is to allow type-specific value when replacing the ? with their respective value.

That's all to it.

Here's a reason of why it's better to use Parameterized Query. Basically, it's easier to read and debug.

If you're using C# 3.0 you can use linq

Or, if you prefer, use the special query syntax provided by the C# 3 compiler:

var filteredList = from x in myList
                   where x > 7
                   select x;

This error occurs when you clone a repo using a call like:

git clone git://github.com/....git

This essentially sets you up as a pull-only user, who can't push up changes.

I fixed this by opening my repo's .git/config file and changing the line:

[remote "origin"]
    url = git://github.com/myusername/myrepo.git

to:

[remote "origin"]
    url = ssh+git://[email protected]/myusername/myrepo.git

This ssh+git protocol with the git user is the authentication mechanism preferred by Github.

The other answers mentioned here technically work, but they all seem to bypass ssh, requiring you to manually enter a password, which you probably don't want.

In my experience, tests of the form if (ptr) or if (!ptr) are preferred. They do not depend on the definition of the symbol NULL. They do not expose the opportunity for the accidental assignment. And they are clear and succinct.

Edit: As SoapBox points out in a comment, they are compatible with C++ classes such as auto_ptr that are objects that act as pointers and which provide a conversion to bool to enable exactly this idiom. For these objects, an explicit comparison to NULL would have to invoke a conversion to pointer which may have other semantic side effects or be more expensive than the simple existence check that the bool conversion implies.

I have a preference for code that says what it means without unneeded text. if (ptr != NULL) has the same meaning as if (ptr) but at the cost of redundant specificity. The next logical thing is to write if ((ptr != NULL) == TRUE) and that way lies madness. The C language is clear that a boolean tested by if, while or the like has a specific meaning of non-zero value is true and zero is false. Redundancy does not make it clearer.

Add jquery into < head>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>

Use $document.ready() : the code can be in < head> or in a separate file like main.js

1) using js in same file (add this in the < head>):

<script>
$( document ).ready(function() {
function what(){
    document.getElementById('hello').innerHTML = 'hi';
};
});
</script>

2) using some other file like main.js (add this in the < head>):

<script type="text/javascript" src="/path/to/main.js" charset="utf-8"></script>

and add the code in main.js file :)

You are most likely getting the TypeError because you need quotes around the datecolumn value.

Try:

now = datetime.datetime(2009, 5, 5)

cursor.execute("INSERT INTO table (name, id, datecolumn) VALUES (%s, %s, '%s')",
               ("name", 4, now))

With regards to the format, I had success with the above command (which includes the milliseconds) and with:

now.strftime('%Y-%m-%d %H:%M:%S')

Hope this helps.

when using (i.e.) getConstructor(String.lang) the constructor has to be declared public. Otherwise a NoSuchMethodException is thrown.

if you want to access a non-public constructor you have to use instead (i.e.) getDeclaredConstructor(String.lang).

try with screen -d -r or screen -D -RR

This is how I did it on Windows 7, after installing OpenSSL (link goes to the Win32 installer, choose the latest version and not the light version).

With this method you only need the .cer file downloaded from Apple.

c:\OpenSSL-Win32\bin\openssl.exe x509 -in aps_development.cer -inform DER -out developer_identity.pem -outform PEM

this will create a file which you will then need to add your private key too.

-----BEGIN PRIVATE KEY-----
MIIEuwIBADANBgkqhk....etc
MIIEuwIBADANBgkqhk....etc
MIIEuwIBADANBgkqhk....etc
MIIEuwIBADANBgkqhk....etc
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
AwIBAgwIBADAwIBADA....etc
AwIBAgwIBADAwIBADA....etc
AwIBAgwIBADAwIBADA....etc
-----END CERTIFICATE-----

That's it.

other alternative is using math operation by dividing it, for example:

switch ((int) num/10) {
    case 1:
        System.out.println("10-19");
        break;
    case 2:
        System.out.println("20-29");
        break;
    case 3:
        System.out.println("30-39");
        break;
    case 4:
        System.out.println("40-49");
        break;
    default:
        break;
}

But, as you can see this can only be used when the range is fixed in each case.

Yeah.... i kinda see what you need. I just came across same problem.

Here is exactly what i did. Now, bear in mind, this some low level knowledge, since i'm just starting. I made my life complicated, so i needed solution. I kinda found it on my own, using different directions from above answers.

I switched from win 10 on HDD to linux on SSD, so i needed my few of .class and .java imported into new workspace.

First i made a mistake, not using export option on windows and i just simply copied all of files from src and bin folders on win 10 to src and bin folders on linux. Of course workspace did not see those files.

Solution was found in IMPORT tool (which i should have used right away).

1. I put all of files in src folder into zipp file, and moved this file to some arbitrary folder (Home folder in my case).

2. Go back to src folder and delete all of .java files (you won't be needing them anymore).

3. Then i opened my empty project and selected import from File menu in Eclipse. In import window, under option General (first one) select Import Archive.

4. Now simply find your zip file, and Voila! All is where it should be.

No, how you are doing it is correct.

http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2

As shown in the latest edit, the password is valid until 1970, which means it's currently invalid. This explains the error message which is the same as if the password was incorrect.

Reset the validity with:

ALTER USER postgres VALID UNTIL 'infinity';

In a recent question, another user had the same problem with user accounts and PG-9.2:

PostgreSQL - Password authentication fail after adding group roles

So apparently there is a way to unintentionally set a bogus password validity to the Unix epoch (1st Jan, 1970, the minimum possible value for the abstime type). Possibly, there's a bug in PG itself or in some client tool that would create this situation.

EDIT: it turns out to be a pgadmin bug. See https://dba.stackexchange.com/questions/36137/

Java Advanced Imaging is now open source, and provides the operations you need.

Yet another parse_requirements hack that also parses environment markers into extras_require:

from collections import defaultdict
from pip.req import parse_requirements

requirements = []
extras = defaultdict(list)
for r in parse_requirements('requirements.txt', session='hack'):
    if r.markers:
        extras[':' + str(r.markers)].append(str(r.req))
    else:
        requirements.append(str(r.req))

setup(
    ...,
    install_requires=requirements,
    extras_require=extras
)

It should support both sdist and binary dists.

As stated by others, parse_requirements has several shortcomings, so this is not what you should do on public projects, but it may suffice for internal/personal projects.

Axivion Bauhaus Suite is a static analysis tool that works with C# (as well as C, C++ and Java).

It provides the following capabilities:

This is an old question, but here is something that might help someone.

From the official docs:

Django provides tools for performing URL reversing that match the different layers where URLs are needed: In templates: Using the url template tag. In Python code: Using the reverse() function. In higher level code related to handling of URLs of Django model instances: The get_absolute_url() method.

Eg. in templates (url tag)

<a href="{% url 'news-year-archive' 2012 %}">2012 Archive</a>

Eg. in python code (using the reverse function)

return HttpResponseRedirect(reverse('news-year-archive', args=(year,)))

1) If file /var/spool/cron/crontabs/root edit via SFTP client - need service cron restart. Reload service not work.

2) If edit file /var/spool/cron/crontabs/root via console linux (nano, mc) - restart NOT need.

3) If edit cron via crontab -e - restart NOT need.

Firstly, PHP doesn't have multi-dimensional arrays, it has arrays of arrays.

Secondly, you can write a function that will do it:

function declare($m, $n, $value = 0) {
  return array_fill(0, $m, array_fill(0, $n, $value));
}

It really helps to understand the LINQ query syntax and how it is translated to LINQ method calls.

It turns out that

var products = from p in _context.Products
               where p.ProductTypeId == 1
               orderby p.LowestPrice.HasValue descending
               orderby p.LowestPrice descending
               select p;

will be translated by the compiler to

var products = _context.Products
                       .Where(p => p.ProductTypeId == 1)
                       .OrderByDescending(p => p.LowestPrice.HasValue)
                       .OrderByDescending(p => p.LowestPrice)
                       .Select(p => p);

This is emphatically not what you want. This sorts by Product.LowestPrice.HasValue in descending order and then re-sorts the entire collection by Product.LowestPrice in descending order.

What you want is

var products = _context.Products
                       .Where(p => p.ProductTypeId == 1)
                       .OrderByDescending(p => p.LowestPrice.HasValue)
                       .ThenBy(p => p.LowestPrice)
                       .Select(p => p);

which you can obtain using the query syntax by

var products = from p in _context.Products
               where p.ProductTypeId == 1
               orderby p.LowestPrice.HasValue descending,
                       p.LowestPrice
               select p;

For details of the translations from query syntax to method calls, see the language specification. Seriously. Read it.

For a bandpass filter, ws is a tuple containing the lower and upper corner frequencies. These represent the digital frequency where the filter response is 3 dB less than the passband.

wp is a tuple containing the stop band digital frequencies. They represent the location where the maximum attenuation begins.

gpass is the maximum attenutation in the passband in dB while gstop is the attentuation in the stopbands.

Say, for example, you wanted to design a filter for a sampling rate of 8000 samples/sec having corner frequencies of 300 and 3100 Hz. The Nyquist frequency is the sample rate divided by two, or in this example, 4000 Hz. The equivalent digital frequency is 1.0. The two corner frequencies are then 300/4000 and 3100/4000.

Now lets say you wanted the stopbands to be down 30 dB +/- 100 Hz from the corner frequencies. Thus, your stopbands would start at 200 and 3200 Hz resulting in the digital frequencies of 200/4000 and 3200/4000.

To create your filter, you'd call buttord as

fs = 8000.0
fso2 = fs/2
N,wn = scipy.signal.buttord(ws=[300/fso2,3100/fso2], wp=[200/fs02,3200/fs02],
   gpass=0.0, gstop=30.0)

The length of the resulting filter will be dependent upon the depth of the stop bands and the steepness of the response curve which is determined by the difference between the corner frequency and stopband frequency.

You can use cvResize. Or better use c++ interface (eg cv::Mat instead of IplImage and cv::imread instead of cvLoadImage) and then use cv::resize which handles memory allocation and deallocation itself.

You cant have multiple ng-view. Below is my use case where I solved my requirement. I wanted to have tabbed behavior in my model dialog. I was facing issue as click on tabs having hyperlink which will invoke router links. I solved this using button and css for tabs. When user clicks on tab, it actually will not call any hyperlink which will always invoke the ng-router. When user click on tab it will call a method, where I dynamcilly load html. Below is the function on click of tab

self.submit = function(form) {
                $templateRequest('resources/items/employee/test_template.html').then(function(template){
                var compiledeHTML = $compile(template)($scope);
                $("#d").replaceWith(compiledeHTML);
});

User $templateRequest. In test_template.html page add your html content. This html content will be bind to your controller.

Request header needs to be set as per below image.

request body can be passed as json string in text area.
