To create Anaconda Prompt using Command Prompt, just create a shortcut file of Command Prompt and modify the shortcut target to:

%windir%\System32\cmd.exe "/K" <Anaconda Location>\anaconda3\Scripts\activate.bat

Example:

%windir%\system32\cmd.exe "/K" C:\Users\user_1\AppData\Local\Continuum\anaconda3\Scripts\activate.bat

This is due to the series df[cat] containing elements that have varying data types e.g.(strings and/or floats). This could be due to the way the data is read, i.e. numbers are read as float and text as strings or the datatype was float and changed after the fillna operation.

In other words

pandas data type 'Object' indicates mixed types rather than str type

so using the following line:

df[cat] = le.fit_transform(df[cat].astype(str))

should help

The 2 in Anaconda2 means that the main version of Python will be 2.x rather than the 3.x installed in Anaconda3. The current release has Python 2.7.13.

The 4.4.0.1 is the version number of Anaconda. The current advertised version is 4.4.0 and I assume the .1 is a minor release or for other similar use. The Windows releases, which I use, just say 4.4.0 in the file name.

Others have now explained the difference between Anaconda and Miniconda, so I'll skip that.

Even I got the same problem when I've first installed Anaconda. It said 'conda' command not found.

So I've just setup two values[added two new paths of Anaconda] system environment variables in the PATH variable which are: C:\Users\mshas\Anaconda2\ & C:\Users\mshas\Anaconda2\Scripts

Lot of people forgot to add the second variable which is "Scripts" just add that then 'conda' command works.

In general, the error ValueError: Wrong number of items passed 3, placement implies 1 suggests that you are attempting to put too many pigeons in too few pigeonholes. In this case, the value on the right of the equation

results['predictedY'] = predictedY

is trying to put 3 "things" into a container that allows only one. Because the left side is a dataframe column, and can accept multiple items on that (column) dimension, you should see that there are too many items on another dimension.

Here, it appears you are using sklearn for modeling, which is where gaussian_process.GaussianProcess() is coming from (I'm guessing, but correct me and revise the question if this is wrong).

Now, you generate predicted values for y here:

predictedY, MSE = gp.predict(testX, eval_MSE = True)

However, as we can see from the documentation for GaussianProcess, predict() returns two items. The first is y, which is array-like (emphasis mine). That means that it can have more than one dimension, or, to be concrete for thick headed people like me, it can have more than one column -- see that it can return (n_samples, n_targets) which, depending on testX, could be (1000, 3) (just to pick numbers). Thus, your predictedY might have 3 columns.

If so, when you try to put something with three "columns" into a single dataframe column, you are passing 3 items where only 1 would fit.

Try installing tensorflow again with the whatever version you want and with option --ignore-installed like:

pip install tensorflow==1.2.0 --ignore-installed

I solved same issue using this command.

I was trying to run this on a pi zero. Turns out the pi zero has an armv6l architecture so the above won't work for pi zero or pi one. Alternatively here I learned that miniconda doesn't have a recent version of miniconda. Instead I used the same instructions posted here to install berryconda3

Conda is now working. Hope this helps those of you interested in running conda on the pi zero!

Had the same issue and I resolved it by using :

conda install protobuf

Anaconda's website addresses this problem here: https://anaconda.org/anaconda/py-xgboost.

conda install -c anaconda py-xgboost

This fixed the problem for me with no problems.

For those of us on corporate networks using web filters that implement trusted man in the middle SSL solutions, it is necessary to add the web-filter certificate to the certifi cacert.pem.

A guide to doing this is here.

Main steps are:

1. connect to https site with browser
2. view and save root certificate
3. convert cert to .pem
4. copy and paste onto end of existing cacert.pem
5. save
6. SSL happiness

Move path\to\anaconda in the PATH above path\to\python

I'm using Ubuntu and I tried as @Arie said above but with this line only in terminal:

sudo apt-get install tcl-dev tk-dev python-tk python3-tk

And it worked!

conda install opencv currently works for me on UNIX/python2. This is worth trying first before consulting other solutions.

The answers are outdated. You simply have to conda install pip and git. Then you can use pip normally:

1. Activate your conda environment source activate myenv

2. conda install git pip

3. pip install git+git://github.com/scrappy/scrappy@master

It turns out that I had not set the path.

To do so, I first had to edit .bash_profile (I downloaded it to my local desktop to do that, I do not know how to text edit a file from linux)

Then add this to .bash_profile:

PATH=$PATH:$HOME/anaconda/bin

No, the only thing that needs to be modified for an Anaconda environment is the PATH (so that it gets the right Python from the environment bin/ directory, or Scripts\ on Windows).

The way Anaconda environments work is that they hard link everything that is installed into the environment. For all intents and purposes, this means that each environment is a completely separate installation of Python and all the packages. By using hard links, this is done efficiently. Thus, there's no need to mess with PYTHONPATH because the Python binary in the environment already searches the site-packages in the environment, and the lib of the environment, and so on.

From the Maven docs, sounds like it's just a difference in which repository you install the package into:

• install - install the package into the local repository, for use as a dependency in other projects locally
• deploy - done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

Maybe there is some confusion in that "install" to the CI server installs it to it's local repository, which then you as a user are sharing?

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

I posted a fix for this here

You can use this function to modify JSON.stringify to encode arrays, just post it near the beginning of your script (check the link above for more detail):

// Upgrade for JSON.stringify, updated to allow arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

It's good to know the differences between margin and padding. Here are some differences:

• Margin is outer space of an element, while padding is inner space of an element.

• Margin is the space outside the border of an element, while padding is the space inside the border of it.

• Margin accepts the value of auto: margin: auto, but you can't set padding to auto.

• Margin can be set to any number, but padding must be non-negative.

• When you style an element, padding will also be affected (e.g. background color), but not margin.

You can't declare an extern local method inside of a method, or any other method with an attribute. Move your DLL import into the class:

using System.Runtime.InteropServices;


public class WindowHandling
{
    [DllImport("User32.dll")]
    public static extern int SetForegroundWindow(IntPtr point);

    public void ActivateTargetApplication(string processName, List<string> barcodesList)
    {
        Process p = Process.Start("notepad++.exe");
        p.WaitForInputIdle();
        IntPtr h = p.MainWindowHandle;
        SetForegroundWindow(h);
        SendKeys.SendWait("k");
        IntPtr processFoundWindow = p.MainWindowHandle;
    }
}

Don't forget, union all is a way to add records to a record set without sorting or merging (as opposed to union).

So for example:

select * from (
    select col1, col2
    from table a
    <....>
    order by col3
    limit by 200
) a
union all
select * from (
    select cola, colb
    from table b
    <....>
    order by colb
    limit by 300
) b

It keeps the individual queries clearer and allows you to sort by different parameters in each query. However by using the selected answer's way it might become clearer depending on complexity and how related the data is because you are conceptualizing the sort. It also allows you to return the artificial column to the querying program so it has a context it can sort by or organize.

But this way has the advantage of being fast, not introducing extra variables, and making it easy to separate out each query including the sort. The ability to add a limit is simply an extra bonus.

And of course feel free to turn the union all into a union and add a sort for the whole query. Or add an artificial id, in which case this way makes it easy to sort by different parameters in each query, but it otherwise is the same as the accepted answer.

What does shapiro.test do?

shapiro.test tests the Null hypothesis that "the samples come from a Normal distribution" against the alternative hypothesis "the samples do not come from a Normal distribution".

How to perform shapiro.test in R?

The R help page for ?shapiro.test gives,

x - a numeric vector of data values. Missing values are allowed, 
    but the number of non-missing values must be between 3 and 5000.

That is, shapiro.test expects a numeric vector as input, that corresponds to the sample you would like to test and it is the only input required. Since you've a data.frame, you'll have to pass the desired column as input to the function as follows:

> shapiro.test(heisenberg$HWWIchg)
#   Shapiro-Wilk normality test

# data:  heisenberg$HWWIchg 
# W = 0.9001, p-value = 0.2528

Interpreting results from shapiro.test:

First, I strongly suggest you read this excellent answer from Ian Fellows on testing for normality.

As shown above, the shapiro.test tests the NULL hypothesis that the samples came from a Normal distribution. This means that if your p-value <= 0.05, then you would reject the NULL hypothesis that the samples came from a Normal distribution. As Ian Fellows nicely put it, you are testing against the assumption of Normality". In other words (correct me if I am wrong), it would be much better if one tests the NULL hypothesis that the samples do not come from a Normal distribution. Why? Because, rejecting a NULL hypothesis is not the same as accepting the alternative hypothesis.

In case of the null hypothesis of shapiro.test, a p-value <= 0.05 would reject the null hypothesis that the samples come from normal distribution. To put it loosely, there is a rare chance that the samples came from a normal distribution. The side-effect of this hypothesis testing is that this rare chance happens very rarely. To illustrate, take for example:

set.seed(450)
x <- runif(50, min=2, max=4)
shapiro.test(x)
#   Shapiro-Wilk normality test
# data:  runif(50, min = 2, max = 4) 
# W = 0.9601, p-value = 0.08995

So, this (particular) sample runif(50, min=2, max=4) comes from a normal distribution according to this test. What I am trying to say is that, there are many many cases under which the "extreme" requirements (p < 0.05) are not satisfied which leads to acceptance of "NULL hypothesis" most of the times, which might be misleading.

Another issue I'd like to quote here from @PaulHiemstra from under comments about the effects on large sample size:

An additional issue with the Shapiro-Wilk's test is that when you feed it more data, the chances of the null hypothesis being rejected becomes larger. So what happens is that for large amounts of data even very small deviations from normality can be detected, leading to rejection of the null hypothesis event though for practical purposes the data is more than normal enough.

Although he also points out that R's data size limit protects this a bit:

Luckily shapiro.test protects the user from the above described effect by limiting the data size to 5000.

If the NULL hypothesis were the opposite, meaning, the samples do not come from a normal distribution, and you get a p-value < 0.05, then you conclude that it is very rare that these samples do not come from a normal distribution (reject the NULL hypothesis). That loosely translates to: It is highly likely that the samples are normally distributed (although some statisticians may not like this way of interpreting). I believe this is what Ian Fellows also tried to explain in his post. Please correct me if I've gotten something wrong!

@PaulHiemstra also comments about practical situations (example regression) when one comes across this problem of testing for normality:

In practice, if an analysis assumes normality, e.g. lm, I would not do this Shapiro-Wilk's test, but do the analysis and look at diagnostic plots of the outcome of the analysis to judge whether any assumptions of the analysis where violated too much. For linear regression using lm this is done by looking at some of the diagnostic plots you get using plot(lm()). Statistics is not a series of steps that cough up a few numbers (hey p < 0.05!) but requires a lot of experience and skill in judging how to analysis your data correctly.

Here, I find the reply from Ian Fellows to Ben Bolker's comment under the same question already linked above equally (if not more) informative:

For linear regression,

1. Don't worry much about normality. The CLT takes over quickly and if you have all but the smallest sample sizes and an even remotely reasonable looking histogram you are fine.

2. Worry about unequal variances (heteroskedasticity). I worry about this to the point of (almost) using HCCM tests by default. A scale location plot will give some idea of whether this is broken, but not always. Also, there is no a priori reason to assume equal variances in most cases.

3. Outliers. A cooks distance of > 1 is reasonable cause for concern.

Those are my thoughts (FWIW).

Hope this clears things up a bit.

It seems like you are essentially looking into computing the z-score or standard score of your data, which is calculated through the formula: z = (x-mean(x))/std(x)

This should work:

%% Original data (Normal with mean 1 and standard deviation 2)
x = 1 + 2*randn(100,1);
mean(x)
var(x)
std(x)

%% Normalized data with mean 0 and variance 1
z = (x-mean(x))/std(x);
mean(z)
var(z)
std(z)

So you can do this

$('#textarea').attr('enable',false)

try it and give feedback

I ran into this issue as well. I don't know the technical details of what was actually happening. However, in my situation, the root cause was that there was cascading deletes setup in the Oracle database and my JPA/Hibernate code was also trying to do the cascading delete calls. So my advice is to make sure that you know exactly what is happening.

Since I can't post a follow-up to android developer's comment, here's an updated answer for anyone else who needs to programmatically set the selected tab indicator color:

tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#FFFFFF"));

Similarly, for height:

tabLayout.setSelectedTabIndicatorHeight((int) (2 * getResources().getDisplayMetrics().density));

These methods were only recently added to revision 23.0.0 of the Support Library, which is why Soheil Setayeshi's answer uses reflection.

In javascript you can do something like this

<input
  ref="fileInput"
  multiple
  type="file"
  style="display: none"
  @change="trySubmitFile"
>

and the function can be something like this.

trySubmitFile(e) {
  if (this.disabled) return;
  const files = e.target.files || e.dataTransfer.files;
  if (files.length > 5) {
    alert('You are only allowed to upload a maximum of 2 files at a time');
  }
  if (!files.length) return;
  for (let i = 0; i < Math.min(files.length, 2); i++) {
    this.fileCallback(files[i]);
  }
}

I am also searching for a solution where this can be limited at the time of selecting files but until now I could not find anything like that.

Linq extension method. Will work with any IEnumerable object:

    public static bool ContainsAny<T>(this IEnumerable<T> Collection, IEnumerable<T> Values)
    {
        return Collection.Any(x=> Values.Contains(x));
    }

Usage:

string[] Array1 = {"1", "2"};
string[] Array2 = {"2", "4"};

bool Array2ItemsInArray1 = List1.ContainsAny(List2);

If Postgres was downloaded and installed, running this should fix the issue:

sudo mkdir -p /etc/paths.d &&
echo /Applications/Postgres.app/Contents/Versions/latest/bin | sudo tee 
/etc/paths.d/postgresapp

Restart the terminal and you'll be able to use psql command.

Ref: https://postgresapp.com/documentation/cli-tools.html

I know the accepted answer is quite old, but there is a way to control formatting with AutoGeneratColumns :

First create a function that will trigger when a column is generated :

<DataGrid x:Name="dataGrid" AutoGeneratedColumns="dataGrid_AutoGeneratedColumns" Margin="116,62,10,10"/>

Then check if the type of the column generated is a DateTime and just change its String format to "d" to remove the time part :

private void DataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
        {
            if(YourColumn == typeof(DateTime))
            {
                e.Column.ClipboardContentBinding.StringFormat = "d";
            }
        }

How to access last element of an array

It looks like that:

var my_array = /* some array here */;
var last_element = my_array[my_array.length - 1];

Which in your case looks like this:

var array1 = loc['f096012e-2497-485d-8adb-7ec0b9352c52'];
var last_element = array1[array1.length - 1];

or, in longer version, without creating new variables:

loc['f096012e-2497-485d-8adb-7ec0b9352c52'][loc['f096012e-2497-485d-8adb-7ec0b9352c52'].length - 1];

How to add a method for getting it simpler

If you are a fan for creating functions/shortcuts to fulfill such tasks, the following code:

if (!Array.prototype.last){
    Array.prototype.last = function(){
        return this[this.length - 1];
    };
};

will allow you to get the last element of an array by invoking array's last() method, in your case eg.:

loc['f096012e-2497-485d-8adb-7ec0b9352c52'].last();

You can check that it works here: http://jsfiddle.net/D4NRN/

Try:

float number mkm = (((((amountdrug/fluidvol)*1000f)/60f)*infrate)/ptwt)*1000f;
int newNum = (int) mkm;
mkm = newNum/1000f; // Will return 3 decimal places

Use .AddWithValue(), So:

sqlComm.Parameters.AddWithValue("@Age", sb.ToString().TrimEnd(','));

Alternatively, you could use this:

sqlComm.Parameters.Add(
    new SqlParameter("@Age", sb.ToString().TrimEnd(',')) { SqlDbType = SqlDbType. NVarChar }
    );

Your total code sample will look at follows then:

string sqlCommand = "SELECT * from TableA WHERE Age IN (@Age)";
SqlConnection sqlCon = new SqlConnection(connectString);
SqlCommand sqlComm = new SqlCommand();
sqlComm.Connection = sqlCon;
sqlComm.CommandType = System.Data.CommandType.Text;
sqlComm.CommandText = sqlCommand;
sqlComm.CommandTimeout = 300;

StringBuilder sb = new StringBuilder();
foreach (ListItem item in ddlAge.Items)
{
     if (item.Selected)
     {
         sb.Append(item.Text + ",");
     }
}

sqlComm.Parameters.AddWithValue("@Age", sb.ToString().TrimEnd(','));

// OR

// sqlComm.Parameters.Add(new SqlParameter("@Age", sb.ToString().TrimEnd(',')) { SqlDbType = SqlDbType. NVarChar });

This error can also be caused by nested <form> tag in the master page which is not allowed.

<form id="someid"></form>

This will likely be the cause if you have picked up a template and copying the code from somewhere as it.

Solution

You have to break the nesting of <form> tag. The following should become

<form method="" name="form1">
  <form method="" name="form2>
  </form>
</form>

should become

<form method="" name="form1">    
</form>

<form method="" name="form2>    
</form>

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr variable at compile time, knowing that the difference between constexpr and static constexpr is that to use static constexpr you ensure the variable is initialized only once.

Following code demonstrates how constexpr variable is initialized multiple times (with same value though), while static constexpr is surely initialized only once.

In addition the code compares the advantage of constexpr against const in combination with static.

#include <iostream>
#include <string>
#include <cassert>
#include <sstream>

const short const_short = 0;
constexpr short constexpr_short = 0;

// print only last 3 address value numbers
const short addr_offset = 3;

// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
    // determine initial size of strings
    std::string title = "value \\ address of ";
    const size_t ref_size = ref_name.size();
    const size_t title_size = title.size();
    assert(title_size > ref_size);

    // create title (resize)
    title.append(ref_name);
    title.append(" is ");
    title.append(title_size - ref_size, ' ');

    // extract last 'offset' values from address
    std::stringstream addr;
    addr << param;
    const std::string addr_str = addr.str();
    const size_t addr_size = addr_str.size();
    assert(addr_size - offset > 0);

    // print title / ref value / address at offset
    std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}

// here we test initialization of const variable (runtime)
void const_value(const short counter)
{
    static short temp = const_short;
    const short const_var = ++temp;
    print_properties("const", &const_var, addr_offset);

    if (counter)
        const_value(counter - 1);
}

// here we test initialization of static variable (runtime)
void static_value(const short counter)
{
    static short temp = const_short;
    static short static_var = ++temp;
    print_properties("static", &static_var, addr_offset);

    if (counter)
        static_value(counter - 1);
}

// here we test initialization of static const variable (runtime)
void static_const_value(const short counter)
{
    static short temp = const_short;
    static const short static_var = ++temp;
    print_properties("static const", &static_var, addr_offset);

    if (counter)
        static_const_value(counter - 1);
}

// here we test initialization of constexpr variable (compile time)
void constexpr_value(const short counter)
{
    constexpr short constexpr_var = constexpr_short;
    print_properties("constexpr", &constexpr_var, addr_offset);

    if (counter)
        constexpr_value(counter - 1);
}

// here we test initialization of static constexpr variable (compile time)
void static_constexpr_value(const short counter)
{
    static constexpr short static_constexpr_var = constexpr_short;
    print_properties("static constexpr", &static_constexpr_var, addr_offset);

    if (counter)
        static_constexpr_value(counter - 1);
}

// final test call this method from main()
void test_static_const()
{
    constexpr short counter = 2;

    const_value(counter);
    std::cout << std::endl;

    static_value(counter);
    std::cout << std::endl;

    static_const_value(counter);
    std::cout << std::endl;

    constexpr_value(counter);
    std::cout << std::endl;

    static_constexpr_value(counter);
    std::cout << std::endl;
}

Possible program output:

value \ address of const is               1 564
value \ address of const is               2 3D4
value \ address of const is               3 244

value \ address of static is              1 C58
value \ address of static is              1 C58
value \ address of static is              1 C58

value \ address of static const is        1 C64
value \ address of static const is        1 C64
value \ address of static const is        1 C64

value \ address of constexpr is           0 564
value \ address of constexpr is           0 3D4
value \ address of constexpr is           0 244

value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0

As you can see yourself constexpr is initilized multiple times (address is not the same) while static keyword ensures that initialization is performed only once.

You need to use the css-property font-face to declare your font. Have a look at this fancy site: http://www.font-face.com/

Example:

@font-face {
  font-family: MyHelvetica;
  src: local("Helvetica Neue Bold"),
       local("HelveticaNeue-Bold"),
       url(MgOpenModernaBold.ttf);
  font-weight: bold;
}

See also: MDN @font-face

Enums are classes that return one instance (like singletons) for each enumeration constant declared by public static final field (immutable) so that == operator could be used to check their equality rather than using equals() method

I think what you are trying to convey can be achieved through multiprocessing. However if you want to do it through threads you can do this. This might help

from threading import Thread
import time

def func1():
    print 'Working'
    time.sleep(2)

def func2():
    print 'Working'
    time.sleep(2)

th = Thread(target=func1)
th.start()
th1=Thread(target=func2)
th1.start()

This is where you can find the answer in the job-dsl-plugin code.

Basically you can do something like this:

readFileFromWorkspace('src/main/groovy/com/groovy/jenkins/scripts/enable_safehtml.groovy')

To use a simple example, I had a counter that needed to summarise unique IP addresses per visited page on a site. Which is basically grouping by pagename and then by IP. I solved it with a combination of DISTINCT and GROUP BY.

SELECT pagename, COUNT(DISTINCT ipaddress) AS visit_count FROM log_visitors GROUP BY pagename ORDER BY visit_count DESC;

To add bold, italic and underline, just add the following to the font argument:

font=("Arial", 8, 'normal', 'bold', 'italic', 'underline')

This example returns the draft field value every time the hidden draft field changes its value (chrome browser):

var h = document.querySelectorAll('input[type="hidden"][name="draft"]')[0];
//or jquery.....
//var h = $('input[type="hidden"][name="draft"]')[0];

observeDOM(h, 'n', function(draftValue){ 
  console.log('dom changed draftValue:'+draftValue);
});


var observeDOM = (function(){
var MutationObserver = window.MutationObserver || 
window.WebKitMutationObserver;

  return function(obj, thistime, callback){
    if(typeof obj === 'undefined'){
      console.log('obj is undefined');
      return;
    }

    if( MutationObserver ){

        // define a new observer
        var obs = new MutationObserver(function(mutations, observer){

            if( mutations[0].addedNodes.length || mutations[0].removedNodes.length ){

               callback('pass other observations back...');

            }else if(mutations[0].attributeName == "value" ){

               // use callback to pass back value of hidden form field                            
               callback( obj.value );

            }

        });

        // have the observer observe obj for changes in children
        // note 'attributes:true' else we can't read the input attribute value
        obs.observe( obj, { childList:true, subtree:true, attributes:true  });

       }
  };
})();

Check out TTTAttributedLabel. It's a drop-in replacement for UILabel that allows you to have mixed font and colors in a single label by setting an NSAttributedString as the text for that label.

You can also use a Power Shell script:

$smtp = new-object Net.Mail.SmtpClient("mail.example.com")

if( $Env:SmtpUseCredentials -eq "true" ) {
    $credentials = new-object Net.NetworkCredential("username","password")
    $smtp.Credentials = $credentials
}
$objMailMessage = New-Object System.Net.Mail.MailMessage
$objMailMessage.From = "[email protected]"
$objMailMessage.To.Add("[email protected]")
$objMailMessage.Subject = "eMail subject Notification"
$objMailMessage.Body = "Hello world!"

$smtp.send($objMailMessage)

listOfSomething.Clear();
listOfSomething.Add("first");
collection.Add(listOfSomething);

You are clearing the list here and adding one element ("first"), the 1st reference of listOfSomething is updated as well sonce both reference the same object, so when you access the second element myList.get(1) (which does not exist anymore) you get the null.

Notice both collection.Add(listOfSomething); save two references to the same arraylist object.

You need to create two different instances for two elements:

ArrayList<ArrayList<String>> collection = new ArrayList<ArrayList<String>>();

ArrayList<String> listOfSomething1 = new ArrayList<String>();
listOfSomething1.Add("first");
listOfSomething1.Add("second");

ArrayList<String> listOfSomething2 = new ArrayList<String>();
listOfSomething2.Add("first");

collection.Add(listOfSomething1);    
collection.Add(listOfSomething2);

When using jQuery in asp.net, if you are using a master page and you are loading the jquery source file there, make sure you have the header contentplaceholder after all the jquery script references.

I had a problem where any pages that used that master page would return '$ is not defined' simply because the incorrect order was making the client side code run before the jquery object was created. So make sure you have:

<head runat="server">
    <script type="text/javascript" src="Scripts/jquery-VERSION#.js"></script>
    <asp:ContentPlaceHolder id="Header" runat="server"></asp:ContentPlaceHolder>
</head>

That way the code will run in order and you will be able to run jQuery code on the child pages.

first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

You can use sort on date field and size=1 parameter. Does it help?

Always nice to have:

Dim myPath As String     
Dim folderPath As String 

folderPath = Application.ActiveWorkbook.Path    
myPath = Application.ActiveWorkbook.FullName

Use reduce() to convert the list to a single dict.

words = "apple banana apple strawberry banana lemon"
reduce( lambda d, c: d.update([(c, d.get(c,0)+1)]) or d, words.split(), {})

returns

{'strawberry': 1, 'lemon': 1, 'apple': 2, 'banana': 2}

check after the form is posted the following

$_FILES["cover_image"]["size"]==0

Put sleep. It will work. I have tried. The reason is that the page wasn't loaded yet. Check this question to know how to wait for load - Wait for page load in Selenium

Try using TabulaPDF (https://github.com/tabulapdf/tabula) . This is very good library to extract table content from the PDF file. It is very as expected.

Good luck. :)

You need something along the lines of this:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(<uri_as_string>);
XPathFactory xPathfactory = XPathFactory.newInstance();
XPath xpath = xPathfactory.newXPath();
XPathExpression expr = xpath.compile(<xpath_expression>);

Then you call expr.evaluate() passing in the document defined in that code and the return type you are expecting, and cast the result to the object type of the result.

If you need help with a specific XPath expressions, you should probably ask it as separate questions (unless that was your question in the first place here - I understood your question to be how to use the API in Java).

Edit: (Response to comment): This XPath expression will get you the text of the first URL element under PowerBuilder:

/howto/topic[@name='PowerBuilder']/url/text()

This will get you the second:

/howto/topic[@name='PowerBuilder']/url[2]/text()

You get that with this code:

expr.evaluate(doc, XPathConstants.STRING);

If you don't know how many URLs are in a given node, then you should rather do something like this:

XPathExpression expr = xpath.compile("/howto/topic[@name='PowerBuilder']/url");
NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);

And then loop over the NodeList.

STATIC_ROOT

The absolute path to the directory where ./manage.py collectstatic will collect static files for deployment. Example: STATIC_ROOT="/var/www/example.com/static/"

now the command ./manage.py collectstatic will copy all the static files(ie in static folder in your apps, static files in all paths) to the directory /var/www/example.com/static/. now you only need to serve this directory on apache or nginx..etc.

STATIC_URL

The URL of which the static files in STATIC_ROOT directory are served(by Apache or nginx..etc). Example: /static/ or http://static.example.com/

If you set STATIC_URL = 'http://static.example.com/', then you must serve the STATIC_ROOT folder (ie "/var/www/example.com/static/") by apache or nginx at url 'http://static.example.com/'(so that you can refer the static file '/var/www/example.com/static/jquery.js' with 'http://static.example.com/jquery.js')

Now in your django-templates, you can refer it by:

{% load static %}
<script src="{% static "jquery.js" %}"></script>

which will render:

<script src="http://static.example.com/jquery.js"></script>

Error: Cannot find module 'C:\Program Files\nodejs\node_modules\npm\bin\node_modules\npm\bin\npm-cli.js'

Look at the above and it is obvious that the path has issue. 'C:\Program Files\nodejs\node_modules\npm\bin\node_modules\npm\bin\npm-cli.js' SHOULD BE CHANGED TO--> 'C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js' which means that "\node_modules\npm\bin" in between was duplicated, which caused such a stupid error. I fixed it by editing the System Variable and updated the PATH as described above.

Drop root privileges after you bind to port 80 (or 443).

This allows port 80/443 to remain protected, while still preventing you from serving requests as root:

function drop_root() {
    process.setgid('nobody');
    process.setuid('nobody');
}

A full working example using the above function:

var process = require('process');
var http = require('http');
var server = http.createServer(function(req, res) {
    res.write("Success!");
    res.end();
});

server.listen(80, null, null, function() {
    console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
    drop_root();
    console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
});

In Swift, using xcode 7 (and later), you can add the following to your AppDelegate.swift file:

UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)

This is the what the complete method looks like:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    // I added this line
    UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)

    return true
}

In the example above my item will be white. The "/255.0" is needed because it expects a value from 0 to 1. For white, I could have just used 1. But for other color you'll probably be using RGB values.

Simply use

$(document).height() // - $('body').offset().top

and / or

$(window).height()

instead of $('body').height();

My answer comes from here

You can make a derived class, which will set the timeout property of the base WebRequest class:

using System;
using System.Net;

public class WebDownload : WebClient
{
    /// <summary>
    /// Time in milliseconds
    /// </summary>
    public int Timeout { get; set; }

    public WebDownload() : this(60000) { }

    public WebDownload(int timeout)
    {
        this.Timeout = timeout;
    }

    protected override WebRequest GetWebRequest(Uri address)
    {
        var request = base.GetWebRequest(address);
        if (request != null)
        {
            request.Timeout = this.Timeout;
        }
        return request;
    }
}

and you can use it just like the base WebClient class.

Here is Some of Most Common Proguard Rules that you need to add in proguard-rules.pro file in Android Sutdio.

ButterKnife

I'd like to make some changes: In C, you can use the built in qsort command:

int compare( const void* a, const void* b)
{
   int int_a = * ( (int*) a );
   int int_b = * ( (int*) b );

   // an easy expression for comparing
   return (int_a > int_b) - (int_a < int_b);
}

qsort( a, 6, sizeof(int), compare )

In IE 5.5+, you can use the contentWindow property:

iframe.height = iframe.contentWindow.document.scrollHeight;

In Netscape 6 (assuming firefox as well), contentDocument property:

iframe.height = iframe.contentDocument.scrollHeight

If you are stuck with a machine where you don't have root access, then it is better to deal with a custom Python installation.

The Anaconda installation worked like a charm:

• Installing packages (SciPy.org)
• Anaconda Python/R Distribution - download

After installation,

[bash]$ /xxx/devTools/python/anaconda/bin/pip list --format=columns | grep numpy

The basic problem while migrating from MySQL I faced was, I thought of the term database to be same in PostgreSQL also, but it is not. So if we are going to switch the database from our application or pgAdmin, the result would not be as expected. As in my case, we have separate schemas (Considering PostgreSQL terminology here.) for each customer and separate admin schema. So in application, I have to switch between schemas.

For this, we can use the SET search_path command. This does switch the current schema to the specified schema name for the current session.

example:

SET search_path = different_schema_name;

This changes the current_schema to the specified schema for the session. To change it permanently, we have to make changes in postgresql.conf file.

First, you have to lookup the correct ArrayList in the HashMap:

ArrayList<String> myAList = theHashMap.get(courseID)

Then, add the new grade to the ArrayList:

myAList.add(newGrade)

enter the values as 0:mm:ss and format as [m]:ss

as this is now in the mins & seconds, simple arithmetic will allow you to calculate your statistics

Based on Ramon's answer I run into an error. The problem where spaces in the JSON I tried to write I got it fixed by changing the task in the playbook to look like:

- copy:
    content: "{{ your_json_feed }}"
    dest: "/path/to/destination/file"

As of now I am not sure why this was needed. My best guess is that it had something to do with how variables are replaced in Ansible and the resulting file is parsed.

I have the same problem, and i try it like this.

<div>
<button type='button' class='btn btn-info btn-file'>Browse</button>
<input type='file' name='image'/>
</div>

The CSS

<style>
.btn-file {
    position:absolute;
}
</style>

The JS

<script>
$(document).ready(function(){
    $('.btn-file').click(function(){
        $('input[name="image"]').click();
    });
});
</script>

Note : The button .btn-file must in the same tag as the input file

Hope you found the best solution...

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

I don't know what you mean by 'manually'. You can choose a colourmap and make a colour array easily enough:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm

x = np.arange(10)
ys = [i+x+(i*x)**2 for i in range(10)]

colors = cm.rainbow(np.linspace(0, 1, len(ys)))
for y, c in zip(ys, colors):
    plt.scatter(x, y, color=c)

Or you can make your own colour cycler using itertools.cycle and specifying the colours you want to loop over, using next to get the one you want. For example, with 3 colours:

import itertools

colors = itertools.cycle(["r", "b", "g"])
for y in ys:
    plt.scatter(x, y, color=next(colors))

Come to think of it, maybe it's cleaner not to use zip with the first one neither:

colors = iter(cm.rainbow(np.linspace(0, 1, len(ys))))
for y in ys:
    plt.scatter(x, y, color=next(colors))

Other answers don't work in angular 5?

I got an error because DatePipe is not a provider, so it cannot be injected. One solution is to put it as a provider in your app module but my preferred solution was to instantiate it.

Instantiate it where needed:

I looked at DatePipe's source code to see how it got the locale: https://github.com/angular/angular/blob/5.2.5/packages/common/src/pipes/date_pipe.ts#L15-L174

I wanted to use it within a pipe, so my example is within another pipe:

    import { Pipe, PipeTransform, Inject, LOCALE_ID } from '@angular/core';
    import { DatePipe } from '@angular/common';

    @Pipe({
        name: 'when',
    })
    export class WhenPipe implements PipeTransform {
        static today = new Date((new Date).toDateString().split(' ').slice(1).join(' '));
        datePipe: DatePipe;

        constructor(@Inject(LOCALE_ID) private locale: string) {
            this.datePipe = new DatePipe(locale);
        }
        transform(value: string | Date): string {
            if (typeof(value) === 'string')
                value = new Date(value);

            return this.datePipe.transform(value, value < WhenPipe.today ? 'MMM d': 'shortTime')
        }
    }

The key here is importing Inject, and LOCALE_ID from angular's core, and then injecting that so you can give it to the DatePipe to instantiate it properly.

Make DatePipe a provider

In your app module you could also add DatePipe to your providers array like this:

    import { DatePipe } from '@angular/common';

    @NgModule({
        providers: [
            DatePipe
        ]
    })

Now you can just have it injected in your constructor where needed (like in cexbrayat's answer).

Summary:

Either solution worked, I don't know which one angular would consider most "correct" but I chose to instantiate it manually since angular didn't provide datepipe as a provider itself.

This is the correct way to replace a portion of text inside a string (based upon the getBetween method by Oscar Jara):

public static string ReplaceTextBetween(string strSource, string strStart, string strEnd, string strReplace)
    {
        int Start, End, strSourceEnd;
        if (strSource.Contains(strStart) && strSource.Contains(strEnd))
        {
            Start = strSource.IndexOf(strStart, 0) + strStart.Length;
            End = strSource.IndexOf(strEnd, Start);
            strSourceEnd = strSource.Length - 1;

            string strToReplace = strSource.Substring(Start, End - Start);
            string newString = string.Concat(strSource.Substring(0, Start), strReplace, strSource.Substring(Start + strToReplace.Length, strSourceEnd - Start));
            return newString;
        }
        else
        {
            return string.Empty;
        }
    }

The string.Concat concatenates 3 strings:

1. The string source portion before the string to replace found - strSource.Substring(0, Start)
2. The replacing string - strReplace
3. The string source portion after the string to replace found - strSource.Substring(Start + strToReplace.Length, strSourceEnd - Start)

If it is exactly null (as opposed to not set):

db.states.find({"cities.name": null})

(but as javierfp points out, it also matches documents that have no cities array at all, I'm assuming that they do).

If it's the case that the property is not set:

db.states.find({"cities.name": {"$exists": false}})

I've tested the above with a collection created with these two inserts:

db.states.insert({"cities": [{name: "New York"}, {name: null}]})
db.states.insert({"cities": [{name: "Austin"}, {color: "blue"}]})

The first query finds the first state, the second query finds the second. If you want to find them both with one query you can make an $or query:

db.states.find({"$or": [
  {"cities.name": null}, 
  {"cities.name": {"$exists": false}}
]})

In EF Core you can enter the command Remove-Migration in the package manager console after you've added your erroneous migration.

The console suggests you do so if your migration could involve a loss of data:

An operation was scaffolded that may result in the loss of data. Please review the migration for accuracy. To undo this action, use Remove-Migration.

I just wanted to add a more effective and generic way to solve this kind of problems. The main idea is about working with sub queries.

do your group by and join the same table on the ID of the table.

your case is more specific since your productId is not unique so there is 2 ways to solve this.

I will begin by the more specific solution: Since your productId is not unique we will need an extra step which is to select DISCTINCT product ids after grouping and doing the sub query like following:

WITH CTE_TEST AS (SELECT productId, SUM(OrderQuantity) Total
                    FROM OrderDetails
                    GROUP BY productId)
SELECT DISTINCT(OrderDetails.ProductID), OrderDetails.ProductName, CTE_TEST.Total
FROM OrderDetails 
INNER JOIN CTE_TEST ON CTE_TEST.ProductID = OrderDetails.ProductID

this returns exactly what is expected

 ProductID     ProductName         Total
    1001          abc               12    
    1002          abc               23
    2002          xyz               8
    3004          ytp               15
    4001          aze               19

But there a cleaner way to do this. I guess that ProductId is a foreign key to products table and i guess that there should be and OrderId primary key (unique) in this table.

in this case there are few steps to do to include extra columns while grouping on only one. It will be the same solution as following

Let's take this t_Value table for example:

If i want to group by description and also display all columns.

All i have to do is:

1. create WITH CTE_Name subquery with your GroupBy column and COUNT condition
2. select all(or whatever you want to display) from value table and the total from the CTE
3. INNER JOIN with CTE on the ID(primary key or unique constraint) column

and that's it!

Here is the query

WITH CTE_TEST AS (SELECT Description, MAX(Id) specID, COUNT(Description) quantity 
                    FROM sch_dta.t_value
                    GROUP BY Description)
SELECT sch_dta.t_Value.*, CTE_TEST.quantity 
FROM sch_dta.t_Value 
INNER JOIN CTE_TEST ON CTE_TEST.specID = sch_dta.t_Value.Id

And here is the result:

@drop-shadow if you're using Hibernate, you can call Hibernate.initialize() when you invoke the getStudents() method:

Public class UniversityDaoImpl extends GenericDaoHibernate<University, Integer> implements UniversityDao {
    //...
    @Override
    public University get(final Integer id) {
        Query query = getQuery("from University u where idUniversity=:id").setParameter("id", id).setMaxResults(1).setFetchSize(1);
        University university = (University) query.uniqueResult();
        ***Hibernate.initialize(university.getStudents());***
        return university;
    }
    //...
}

>>> re.split('(\W)', 'foo/bar spam\neggs')
['foo', '/', 'bar', ' ', 'spam', '\n', 'eggs']

If you're in control of the string, you could also use a 'Raw' string type:

>>> string = r"abcd\n"
>>> print(string)
abcd\n

I had a similir problem, but in my case, I put a row in the leading of the ListView, and it was consuming all the space, of course. I just had to take the Row out of the leading, and it was solved. I would recommend to check if the problem is a larger widget than its container can have.

Expanded(child:MyListView())

This is solved in my case.

You can handle click on list view item like this:

<ListView.ItemTemplate>
  <DataTemplate>
     <Button BorderBrush="Transparent" Background="Transparent" Focusable="False">
        <i:Interaction.Triggers>
                <i:EventTrigger EventName="Click">
                    <i:InvokeCommandAction Command="{Binding DataContext.MyCommand, ElementName=ListViewName}" CommandParameter="{Binding}"/>
                </i:EventTrigger>
        </i:Interaction.Triggers>
      <Button.Template>
      <ControlTemplate>
         <Grid VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
    ...

I created some methods based Daniel's reply above.

-(CGFloat)heightForLabel:(UILabel *)label withText:(NSString *)text
{
    CGSize maximumLabelSize     = CGSizeMake(290, FLT_MAX);

    CGSize expectedLabelSize    = [text sizeWithFont:label.font
                                constrainedToSize:maximumLabelSize
                                    lineBreakMode:label.lineBreakMode];

    return expectedLabelSize.height;
}

-(void)resizeHeightToFitForLabel:(UILabel *)label
{
    CGRect newFrame         = label.frame;
    newFrame.size.height    = [self heightForLabel:label withText:label.text];
    label.frame             = newFrame;
}

-(void)resizeHeightToFitForLabel:(UILabel *)label withText:(NSString *)text
{
    label.text              = text;
    [self resizeHeightToFitForLabel:label];
}

I was also trying to achieve this. From above codes, what I understood was that you can call getch() function multiple times in order to get both bytes getting from the function. So the ord() function is not necessary if you are just looking to use with byte objects.

while True :
    if m.kbhit() :
        k = m.getch()
        if b'\r' == k :
            break
        elif k == b'\x08'or k == b'\x1b':
            # b'\x08' => BACKSPACE
            # b'\x1b' => ESC
            pass
        elif k == b'\xe0' or k == b'\x00':
            k = m.getch()
            if k in [b'H',b'M',b'K',b'P',b'S',b'\x08']:
                # b'H' => UP ARROW
                # b'M' => RIGHT ARROW
                # b'K' => LEFT ARROW
                # b'P' => DOWN ARROW
                # b'S' => DELETE
                pass
            else:
                print(k.decode(),end='')
        else:
            print(k.decode(),end='')

This code will work print any key until enter key is pressed in CMD or IDE (I was using VS CODE) You can customize inside the if for specific keys if needed

As an alternative (mostly on aesthetics) to Ted Petrou's answer, I found I preferred a slightly more compact listing. Please don't consider accepting it, it's just a much-more-detailed comment on Ted's answer, plus code/data. Python/pandas is not my first/best, but I found this to read well:

df.groupby('group') \
  .apply(lambda x: pd.Series({
      'a_sum'       : x['a'].sum(),
      'a_max'       : x['a'].max(),
      'b_mean'      : x['b'].mean(),
      'c_d_prodsum' : (x['c'] * x['d']).sum()
  })
)

          a_sum     a_max    b_mean  c_d_prodsum
group                                           
0      0.530559  0.374540  0.553354     0.488525
1      1.433558  0.832443  0.460206     0.053313

I find it more reminiscent of dplyr pipes and data.table chained commands. Not to say they're better, just more familiar to me. (I certainly recognize the power and, for many, the preference of using more formalized def functions for these types of operations. This is just an alternative, not necessarily better.)

I generated data in the same manner as Ted, I'll add a seed for reproducibility.

import numpy as np
np.random.seed(42)
df = pd.DataFrame(np.random.rand(4,4), columns=list('abcd'))
df['group'] = [0, 0, 1, 1]
df

          a         b         c         d  group
0  0.374540  0.950714  0.731994  0.598658      0
1  0.156019  0.155995  0.058084  0.866176      0
2  0.601115  0.708073  0.020584  0.969910      1
3  0.832443  0.212339  0.181825  0.183405      1

All the other solutions posted here cause the toggle to get out of sync if it is double clicked. The following solution uses the events provided by the Bootstrap framework, and the toggle always matches the state of the collapsible element:

HTML:

<div class="row-fluid summary">
    <div class="span11">
        <h2>MyHeading</h2>  
    </div>
    <div class="span1">
        <button id="intro-switch" class="btn btn-success" data-toggle="collapse" data-target="#intro">+</button>
    </div>
</div>
<div class="row-fluid summary">
    <div id="intro" class="collapse"> 
        Here comes the text...
    </div>
</div>

JS:

$('#intro').on('show', function() {
  $('#intro-switch').html('-')
})
$('#intro').on('hide', function() {
  $('#intro-switch').html('+')
})

That should work for most cases.

However, I also ran into an additional problem when trying to nest one collapsible element and its toggle switch inside another collapsible element. With the above code, when I click the nested toggle to hide the nested collapsible element, the toggle for the parent element also changes. It may be a bug in Bootstrap. I found a solution that seems to work: I added a "collapsed" class to the toggle switches (Bootstrap adds this when the collapsible element is hidden but they don't start out with it), then added that to the jQuery selector for the hide function:

http://jsfiddle.net/fVpkm/87/

HTML:

<div class="row-fluid summary">
    <div class="span11">
        <h2>MyHeading</h2>  
    </div>
    <div class="span1">
        <button id="intro-switch" class="btn btn-success collapsed" data-toggle="collapse" data-target="#intro">+</button>
    </div>
</div>
<div class="row-fluid summary">
    <div id="intro" class="collapse"> 
        Here comes the text...<br>
        <a id="details-switch" class="collapsed" data-toggle="collapse" href="#details">Show details</a>
        <div id="details" class="collapse">
            More details...
        </div>
    </div>
</div>

JS:

$('#intro').on('show', function() {
    $('#intro-switch').html('-')
})
$('#intro').on('hide', function() {
    $('#intro-switch.collapsed').html('+')
})

$('#details').on('show', function() {
    $('#details-switch').html('Hide details')
})
$('#details').on('hide', function() {
    $('#details-switch.collapsed').html('Show details')
})

First of all, let's try to make your code a little simpler:

// No need to create a circle unless it is clearly necessary to
// demonstrate the problem

// Your Rect2f defines a default constructor, so let's use it for simplicity.
shared_ptr<Shape> rect(new Rect2f());

Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:

int main() {
    delete new T();
}

This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:

In function 'int main()':
Line 2: error: expected type-specifier before 'T'

Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f.

I want to add to the answers above that it becomes a little more difficult if Jenkins authorization is enabled.

After enabling it I got an error message that anonymous user needs read permission.

I saw two possible solutions:

1: Changing my hook to:

curl --user name:passwd -s http://domain?token=whatevertokenuhave

2: setting project based authorization.

The former solutions has the disadvantage that I had to expose my passwd in the hook file. Unacceptable in my case.

The second works for me. In the global auth settings I had to enable Overall>Read for Anonymous user. In the project I wanted to trigger I had to enable Job>Build and Job>Read for Anonymous.

This is still not a perfect solution because now you can see the project in Jenkins without login. There might be an even better solution using the former approach with http login but I haven't figured it out.

As a complement to other's answers, it's possible to desaturate an image half the way on FF without SVG's matrix's headaches:

<feColorMatrix type="saturate" values="$v" />

Where $v is between 0 and 1. It's equivalent to filter:grayscale(50%);.

Live example:

.desaturate {_x000D_
    filter: url("#desaturate");_x000D_
    -webkit-filter: grayscale(50%);_x000D_
}_x000D_
figcaption{_x000D_
    background: rgba(55, 55, 136, 1);_x000D_
    padding: 4px 98px 0 18px;_x000D_
    color: white;_x000D_
    display: inline-block;_x000D_
    border-top-left-radius: 8px;_x000D_
    border-top-right-radius: 100%;_x000D_
    font-family: "Helvetica";_x000D_
}

<svg version="1.1" xmlns="http://www.w3.org/2000/svg">_x000D_

I agree that it isn't sufficient to Select *, if that one you don't need, as mentioned elsewhere, is a BLOB, you don't want to have that overhead creep in.

I would create a view with the required data, then you can Select * in comfort --if the database software supports them. Else, put the huge data in another table.

Use count(d.ertek) or count(d.id) instead of count(d). This can be happen when you have composite primary key at your entity.

You could manipulate the image itself, but a much better way is to simply add a UIView that contains the UIImageView, and change the background to black. Then set the size of that container view to a little bit larger than the UIImageView.

This should works with windows server 2012 and IE.

var alert = driver.SwitchTo().Alert();

alert.SetAuthenticationCredentials("username", "password");

alert.Accept();

I'm the author of la4j (Linear Algebra for Java) library and here is my point. I've been working on la4j for 3 years (the latest release is 0.4.0 [01 Jun 2013]) and only now I can start doing performace analysis and optimizations since I've just covered the minimal required functional. So, la4j isn't as fast as I wanted but I'm spending loads of my time to change it.

I'm currently in the middle of porting new version of la4j to JMatBench platform. I hope new version will show better performance then previous one since there are several improvement I made in la4j such as much faster internal matrix format, unsafe accessors and fast blocking algorithm for matrix multiplications.

You have to update Xcode to the newest one (v7.0.1) and everything will work as normal.

If after you install the newest Xcode and still doesn't work try to install gem in this way:

sudo gem install -n /usr/local/bin GEM_NAME_HERE

For example:

sudo gem install -n /usr/local/bin fakes3
sudo gem install -n /usr/local/bin compass
sudo gem install -n /usr/local/bin susy

Do:

NSData *data = [yourString dataUsingEncoding:NSUTF8StringEncoding];

then feel free to proceed with NSJSONSerialization:JSONObjectWithData.

Correction to the answer regarding the NULL terminator

Following the comments, official documentation, and verifications, this answer was updated regarding the removal of an alleged NULL terminator:

1. As documented by dataUsingEncoding::

   Return Value

   The result of invoking dataUsingEncoding:allowLossyConversion: with NO as the second argument

2. As documented by getCString:maxLength:encoding: and cStringUsingEncoding::

   note that the data returned by dataUsingEncoding:allowLossyConversion: is not a strict C-string since it does not have a NULL terminator

Is sku just a property of the Product model? If so:

$products = Product::whereOwnerAndStatus($owner, 0)->take($count)->get();

foreach ($products as $product ) {
  // Access $product->sku here...
}

Or is sku a relationship to another model? If that is the case, then, as long as your relationship is setup properly, you code should work.

We Can use this method for changing the column index but should be applied to all the columns if there are more than two number of columns otherwise it will show all the Improper values from data table....................

Man, you guys/gals like to over complicate things... Use:

rename 'y/A-Z/a-z/' *

If you're anything like me, you won't want to go through changing each index every time you want to change the column you're sorting by.

function sortByColumn(a, colIndex){

    a.sort(sortFunction);

    function sortFunction(a, b) {
        if (a[colIndex] === b[colIndex]) {
            return 0;
        }
        else {
            return (a[colIndex] < b[colIndex]) ? -1 : 1;
        }
    }

    return a;
}

var sorted_a = sortByColumn(a, 2);

A callback is some code that you pass to a given method, so that it can be called at a later time.

In Java one obvious example is java.util.Comparator. You do not usually use a Comparator directly; rather, you pass it to some code that calls the Comparator at a later time:

Example:

class CodedString implements Comparable<CodedString> {
    private int code;
    private String text;

    ...

    @Override
    public boolean equals() {
        // member-wise equality
    }

    @Override
    public int hashCode() {
        // member-wise equality 
    }

    @Override
    public boolean compareTo(CodedString cs) {
        // Compare using "code" first, then
        // "text" if both codes are equal.
    }
}

...

public void sortCodedStringsByText(List<CodedString> codedStrings) {
    Comparator<CodedString> comparatorByText = new Comparator<CodedString>() {
        @Override
        public int compare(CodedString cs1, CodedString cs2) {
            // Compare cs1 and cs2 using just the "text" field
        }
    }

    // Here we pass the comparatorByText callback to Collections.sort(...)
    // Collections.sort(...) will then call this callback whenever it
    // needs to compare two items from the list being sorted.
    // As a result, we will get the list sorted by just the "text" field.
    // If we do not pass a callback, Collections.sort will use the default
    // comparison for the class (first by "code", then by "text").
    Collections.sort(codedStrings, comparatorByText);
}

Set the socket non-blocking, and use select() (which takes a timeout parameter). If a non-blocking socket is trying to connect, then select() will indicate that the socket is writeable when the connect() finishes (either successfully or unsuccessfully). You then use getsockopt() to determine the outcome of the connect():

int main(int argc, char **argv) {
    u_short port;                /* user specified port number */
    char *addr;                  /* will be a pointer to the address */
    struct sockaddr_in address;  /* the libc network address data structure */
    short int sock = -1;         /* file descriptor for the network socket */
    fd_set fdset;
    struct timeval tv;

    if (argc != 3) {
        fprintf(stderr, "Usage %s <port_num> <address>\n", argv[0]);
        return EXIT_FAILURE;
    }

    port = atoi(argv[1]);
    addr = argv[2];

    address.sin_family = AF_INET;
    address.sin_addr.s_addr = inet_addr(addr); /* assign the address */
    address.sin_port = htons(port);            /* translate int2port num */

    sock = socket(AF_INET, SOCK_STREAM, 0);
    fcntl(sock, F_SETFL, O_NONBLOCK);

    connect(sock, (struct sockaddr *)&address, sizeof(address));

    FD_ZERO(&fdset);
    FD_SET(sock, &fdset);
    tv.tv_sec = 10;             /* 10 second timeout */
    tv.tv_usec = 0;

    if (select(sock + 1, NULL, &fdset, NULL, &tv) == 1)
    {
        int so_error;
        socklen_t len = sizeof so_error;

        getsockopt(sock, SOL_SOCKET, SO_ERROR, &so_error, &len);

        if (so_error == 0) {
            printf("%s:%d is open\n", addr, port);
        }
    }

    close(sock);
    return 0;
}

I just wanted to share my approach as this might it might help someone:

I basically included a JavaScript module which handles the authentication stuff like displaying the username and also this case handling the redirect to the login page.

My scenario: We basically have an ISA server in between which listens to all requests and responds with a 302 and a location header to our login page.

In my JavaScript module my initial approach was something like

$(document).ajaxComplete(function(e, xhr, settings){
    if(xhr.status === 302){
        //check for location header and redirect...
    }
});

The problem (as many here already mentioned) is that the browser handles the redirect by itself wherefore my ajaxComplete callback got never called, but instead I got the response of the already redirected Login page which obviously was a status 200. The problem: how do you detect whether the successful 200 response is your actual login page or just some other arbitrary page??

The solution

Since I was not able to capture 302 redirect responses, I added a LoginPage header on my login page which contained the url of the login page itself. In the module I now listen for the header and do a redirect:

if(xhr.status === 200){
    var loginPageRedirectHeader = xhr.getResponseHeader("LoginPage");
    if(loginPageRedirectHeader && loginPageRedirectHeader !== ""){
        window.location.replace(loginPageRedirectHeader);
    }
}

...and that works like charm :). You might wonder why I include the url in the LoginPage header...well basically because I found no way of determining the url of GET resulting from the automatic location redirect from the xhr object...

You can return empty array by following two ways:

If you want to return array of int then

1. Using {}:

   int arr[] = {};
   return arr;
   

2. Using new int[0]:

   int arr[] = new int[0];
   return arr;
   

Same way you can return array for other datatypes as well.

In SVG (contrasted with HTML), you will want to use <image> instead of <img> for elements.

Try changing your last block with:

var imgs = svg.selectAll("image").data([0]);
            imgs.enter()
            .append("svg:image")
            ...

Easiest way is to use the built-in feature of SQL Management Studio.

Right-click the database, go to tasks, Generate Scripts, and walk through the wizard. You can choose what objects to script, and it'll make it all for you.

Now if you are trying to make your OWN script to do the same thing, you're probably up for a lot of work...

I created a crude and simple jsonOBJ class to use for my code. PHP does not include json functions like JavaScript/Node do. You have to iterate differently, but may be helpful.

<?php

// define a JSON Object class
class jsonOBJ {
    private $_arr;
    private $_arrName;

    function __construct($arrName){
        $this->_arrName = $arrName;
        $this->_arr[$this->_arrName] = array();

    }

    function toArray(){return $this->_arr;}
    function toString(){return json_encode($this->_arr);}

    function push($newObjectElement){
        $this->_arr[$this->_arrName][] = $newObjectElement; // array[$key]=$val;
    }

    function add($key,$val){
        $this->_arr[$this->_arrName][] = array($key=>$val);
    }
}

// create an instance of the object
$jsonObj = new jsonOBJ("locations");

// add items using one of two methods
$jsonObj->push(json_decode("{\"location\":\"TestLoc1\"}",true)); // from a JSON String
$jsonObj->push(json_decode("{\"location\":\"TestLoc2\"}",true));

$jsonObj->add("location","TestLoc3"); // from key:val pairs

echo "<pre>" . print_r($jsonObj->toArray(),1) . "</pre>";
echo "<br />" . $jsonObj->toString();
?>

Will output:

Array
(
    [locations] => Array
        (
            [0] => Array
                (
                    [location] => TestLoc1
                )

            [1] => Array
                (
                    [location] => TestLoc2
                )

            [2] => Array
                (
                    [location] => TestLoc3
                )

        )

)


{"locations":[{"location":"TestLoc1"},{"location":"TestLoc2"},{"location":"TestLoc3"}]}

To iterate, convert to a normal object:

$myObj = $jsonObj->toArray();

Then:

foreach($myObj["locations"] as $locationObj){
    echo $locationObj["location"] ."<br />";
}

Outputs:

TestLoc1
TestLoc2
TestLoc3

Access direct:

$location = $myObj["locations"][0]["location"];
$location = $myObj["locations"][1]["location"];

A practical example:

// return a JSON Object (jsonOBJ) from the rows
    function ParseRowsAsJSONObject($arrName, $rowRS){
        $jsonArr = new jsonOBJ($arrName); // name of the json array

        $rows = mysqli_num_rows($rowRS);
        if($rows > 0){
            while($rows > 0){
                $rd = mysqli_fetch_assoc($rowRS);
                $jsonArr->push($rd);
                $rows--;
            }
            mysqli_free_result($rowRS);
        }
        return $jsonArr->toArray();
    }

Just for fun, I found an interesting article here, to use a somehow hidden evaluate function that does exist in Excel. The trick is to assign it to a name, and use the name in your cells, because EVALUATE() would give you an error msg if used directly in a cell. I tried and it works! You can use it with a relative name, if you want to copy accross rows if a sheet.

    'First check if the last row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        If Application.CountBlank(lastRow) < lastRow.Columns.Count Then
            table.ListRows.Add
        End If
    End If

    'Iterate through the last row and populate it with the entries from values()
    Set lastRow = table.ListRows(table.ListRows.Count).Range
    For col = 1 To lastRow.Columns.Count
        If col <= UBound(NewData) + 1 Then lastRow.Cells(1, col) = NewData(col - 1)
    Next col
End Sub

New Data in Horizontal Range:

Sub AddDataRow(tableName As String, NewData As Range)
    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = Range(tableName).Parent
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last table row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        If Application.CountBlank(lastRow) < lastRow.Columns.Count Then
            table.ListRows.Add
        End If
    End If

    'Copy NewData to new table record
    Set lastRow = table.ListRows(table.ListRows.Count).Range
    lastRow.Value = NewData.Value
End Sub

false == 0 and true = !false

i.e. anything that is not zero and can be converted to a boolean is not false, thus it must be true.

Some examples to clarify:

if(0)          // false
if(1)          // true
if(2)          // true
if(0 == false) // true
if(0 == true)  // false
if(1 == false) // false
if(1 == true)  // true
if(2 == false) // false
if(2 == true)  // false
cout << false  // 0
cout << true   // 1

true evaluates to 1, but any int that is not false (i.e. 0) evaluates to true but is not equal to true since it isn't equal to 1.

Excellent solution! I noticed when I tried to implement it that if I returned a value in the success clause, it came back as undefined. I had to store it in a variable and return that variable. This is the method I came up with:

function getWhatever() {
  // strUrl is whatever URL you need to call
  var strUrl = "", strReturn = "";

  jQuery.ajax({
    url: strUrl,
    success: function(html) {
      strReturn = html;
    },
    async:false
  });

  return strReturn;
}

The range function in python has the syntax:

range(start, end, step)

It has the same syntax as python lists where the start is inclusive but the end is exclusive.

So if you want to count from 5 to 1, you would use range(5,0,-1) and if you wanted to count from last to posn you would use range(last, posn - 1, -1).

According to my perspective,

O(1) means time to execute one operation or instruction at a time is one, in time complexity analysis of algorithm for best case.

How about something like

=LEFT(A1,SEARCH(" ",A1)-1)

or

=LEFT(A1,SEARCH("<b>",A1)-1)

Have a look at MS Excel: Search Function and Excel 2007 LEFT Function

I use a generic query I call "dump" (why? I don't know) that looks like this:

SET NEWPAGE NONE
SET PAGESIZE 0
SET SPACE 0
SET LINESIZE 16000
SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON
SET TRIMSPOOL ON
SET COLSEP |

spool &1..txt

@@&1

spool off
exit

I then call SQL*Plus passing the actual SQL script I want to run as an argument:

sqlplus -S user/password@database @dump.sql my_real_query.sql

The result is written to a file

my_real_query.sql.txt

.

I had exactly the same problem. My environment was:

• Spring STS 3.7.3.RELEASE
• Build Id: 201602250940
• Platform: Eclipse Mars.2 (4.5.2)

The symptoms of the problems were:

1. There was a red error flag on my PM file. and the description of the error was as described in the original question asked here.
2. There were known compilation problems in the several Java files in the project, but eclipse still was not showing them flagged as error in the editor pane as well as the project explorer tree on the left side.

The solution (described above) about updating the m2e extensions worked for me.

Better solution (my recommondation):

• update Eclipse m2e extensions
• From Help > Install New Software.., add a new repository (via the Add.. option), pointing to the following URL: https://otto.takari.io/content/sites/m2e.extras/m2eclipse-mavenarchiver/0.17.2/N/LATEST/
• Select the m2e extensions, accept the license.
• After update, you will be asked for restarting STS. The problem goes away after STS comes back up.

I have written a general purpose XML parser that can easily handle GB files. It's based on XMLReader and it's very easy to use:

$source = new XmlExtractor("path/to/tag", "/path/to/file.xml");
foreach ($source as $tag) {
    echo $tag->field1;
    echo $tag->field2->subfield1;
}

Here's the github repo: XmlExtractor

If you are using beeline to connect to hive, then !dbinfo will give all the underlying database details and in the output getDatabaseProductVersion will have the hive database version.

Sample output: getDatabaseProductVersion 1.2.1000.2.4.3.0-227

This is a new feature of C# 6 called an expression bodied member that allows you to define a getter only property using a lambda like function.

While it is considered syntactic sugar for the following, they may not produce identical IL:

public int MaxHealth
{
    get
    {
        return Memory[Address].IsValid
               ?   Memory[Address].Read<int>(Offs.Life.MaxHp)
               :   0;
    }
}

It turns out that if you compile both versions of the above and compare the IL generated for each you'll see that they are NEARLY the same.

Here is the IL for the classic version in this answer when defined in a class named TestClass:

.property instance int32 MaxHealth()
{
    .get instance int32 TestClass::get_MaxHealth()
}

.method public hidebysig specialname 
    instance int32 get_MaxHealth () cil managed 
{
    // Method begins at RVA 0x2458
    // Code size 71 (0x47)
    .maxstack 2
    .locals init (
        [0] int32
    )

And here is the IL for the expression bodied member version when defined in a class named TestClass:

.property instance int32 MaxHealth()

    .get instance int32 TestClass::get_MaxHealth()
}

.method public hidebysig specialname

Aditionally to the answer from @srk, you should uninstall package setuptools:

python -m pip uninstall pip setuptools

If you want to uninstall all other packages first, this answer has some hints: https://stackoverflow.com/a/11250821/265954

Note: before you use the commands from that answer, please carefully read the comments about side effects and how to avoid uninstalling pip and setuptools too early. E.g. pip freeze | grep -v "^-e" | grep -v "^(setuptools|pip)" | xargs pip uninstall -y

The changelog is sloppily worded. from __future__ import absolute_import does not care about whether something is part of the standard library, and import string will not always give you the standard-library module with absolute imports on.

from __future__ import absolute_import means that if you import string, Python will always look for a top-level string module, rather than current_package.string. However, it does not affect the logic Python uses to decide what file is the string module. When you do

python pkg/script.py

pkg/script.py doesn't look like part of a package to Python. Following the normal procedures, the pkg directory is added to the path, and all .py files in the pkg directory look like top-level modules. import string finds pkg/string.py not because it's doing a relative import, but because pkg/string.py appears to be the top-level module string. The fact that this isn't the standard-library string module doesn't come up.

To run the file as part of the pkg package, you could do

python -m pkg.script

In this case, the pkg directory will not be added to the path. However, the current directory will be added to the path.

You can also add some boilerplate to pkg/script.py to make Python treat it as part of the pkg package even when run as a file:

if __name__ == '__main__' and __package__ is None:
    __package__ = 'pkg'

However, this won't affect sys.path. You'll need some additional handling to remove the pkg directory from the path, and if pkg's parent directory isn't on the path, you'll need to stick that on the path too.

You can use the regex

(\s)\1

and

replace it with $1.

Java code:

str = str.replaceAll("(\\s)\\1","$1");

If the input is "foo\t\tbar " you'll get "foo\tbar " as output
But if the input is "foo\t bar" it will remain unchanged because it does not have any consecutive whitespace characters.

If you treat all the whitespace characters(space, vertical tab, horizontal tab, carriage return, form feed, new line) as space then you can use the following regex to replace any number of consecutive white space with a single space:

str = str.replaceAll("\\s+"," ");

But if you want to replace two consecutive white space with a single space you should do:

str = str.replaceAll("\\s{2}"," ");

The key function helped me and is very simple:

The key() function simply returns the key of the array element that's currently being pointed to by the internal pointer. It does not move the pointer in any way. If the internal pointer points beyond the end of the elements list or the array is empty, key() returns NULL.

Example:

<?php
    $array = array(
        'fruit1' => 'apple',
        'fruit2' => 'orange',
        'fruit3' => 'grape',
        'fruit4' => 'apple',
        'fruit5' => 'apple');

    // this cycle echoes all associative array
    // key where value equals "apple"
    while ($fruit_name = current($array)) {
        if ($fruit_name == 'apple') {
            echo key($array).'<br />';
        }
        next($array);
    }
?>

The above example will output:

fruit1<br />
fruit4<br />
fruit5<br />

Java

driver.manage().window().maximize();

Python

driver.maximize_window()

Ruby

@driver.manage.window.maximize

OR

max_width, max_height = driver.execute_script("return [window.screen.availWidth, window.screen.availHeight];")
@driver.manage.window.resize_to(max_width, max_height)

OR

target_size = Selenium::WebDriver::Dimension.new(1600, 1268)
@driver.manage.window.size = target_size

Option 1: Likely fastest (but not supported by some browsers if used on Document or SVGElement) :

var elements = document.getElementById('parentContainer').children;

Option 2: Likely slowest :

var elements = document.getElementById('parentContainer').getElementsByTagName('*');

Option 3: Requires change to code (wrap a form instead of a div around it) :

// Since what you're doing looks like it should be in a form...
var elements = document.forms['parentContainer'].elements;

var matches = [];

for (var i = 0; i < elements.length; i++)
    if (elements[i].value.indexOf('q17_') == 0)
        matches.push(elements[i]);

For somebody who is interested in a such map because you want to reduce footprint of autoboxing in Java of wrappers over primitives types, I would recommend to use Eclipse collections. Trove isn't supported any more, and I believe it is quite unreliable library in this sense (though it is quite popular anyway) and couldn't be compared with Eclipse collections.

import org.eclipse.collections.impl.map.mutable.primitive.IntObjectHashMap;

public class Check {
    public static void main(String[] args) {
        IntObjectHashMap map = new IntObjectHashMap();

        map.put(5,"It works");
        map.put(6,"without");
        map.put(7,"boxing!");

        System.out.println(map.get(5));
        System.out.println(map.get(6));
        System.out.println(map.get(7));
    }
}

In this example above IntObjectHashMap.

As you need int->object mapping, also consider usage of YourObjectType[] array or List<YourObjectType> and access values by index, as map is, by nature, an associative array with int type as index.

For me I did enter a invalid url like : orcl only instead of jdbc:oracle:thin:@//localhost:1521/orcl

I had to change:

function start_lvl(&$output, $depth)

to:

function start_lvl( &$output, $depth = 0, $args = array() )

Because I was getting an incompatibility error:

Strict Standards: Declaration of My_Walker_Nav_Menu::start_lvl() should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array)

You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.

Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.

You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.

The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.

You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.

Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.

But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).

You should provide @2x images for the Retina Macbook Pro and future Retina Macs.

Hive database is nothing but directories within HDFS with .db extensions.

So, from a Unix or Linux host which is connected to HDFS, search by following based on type of HDFS distribution:

hdfs dfs -ls -R / 2>/dev/null|grep db or hadoop fs -ls -R / 2>/dev/null|grep db

You will see full path of .db database directories. All tables will be residing under respective .db database directories.

With the differents answers, I implemented this code to use an external file JSON loaded in "app.locals"

Parameters

        "title" : "Le titre de ma Page",
        "cssFile" : "20200608_1018.css"
    }
}

Application

var express     = require('express');
var appli       = express();
var serveur     = require('http').Server(appli);

var myParams    = require('./include/my_params.json');
var myFonctions = require('./include/my_fonctions.js');

appli.locals = myParams;

If you have a rooted device you can use kill command

Connect to your device with adb:

adb shell

Once the session is established, you have to escalade privileges:

su

Then

ps

will list running processes. Note down the PID of the process you want to terminate. Then get rid of it

kill PID

If your x and y coords are not on a grid then you need to interpolate your x,y,z surface onto one. You can do this with kriging using any of the geostatistics packages (geoR, gstat, others) or simpler techniques such as inverse distance weighting.

I'm guessing the 'interp' function you mention is from the akima package. Note that the output matrix is independent of the size of your input points. You could have 10000 points in your input and interpolate that onto a 10x10 grid if you wanted. By default akima::interp does it onto a 40x40 grid:

require(akima)
require(rgl)

x = runif(1000)
y = runif(1000)
z = rnorm(1000)
s = interp(x,y,z)
> dim(s$z)
[1] 40 40
surface3d(s$x,s$y,s$z)

That'll look spiky and rubbish because its random data. Hopefully your data isnt!

I also search for an answer to your question. Correspond to the answers the correct import all function does not exist.

Thats why I have written a python script which you need to place into the root of your scss folder like so:

- scss
  |- scss-crawler.py
  |- abstract
  |- base
  |- components
  |- layout
  |- themes
  |- vender

It will then walk through the tree and find all scss files. Once executed, it will create a scss file called main.scss

#python3
import os

valid_file_endings = ["scss"]

with open("main.scss", "w") as scssFile:
    for dirpath, dirs, files in os.walk("."):
        # ignore the current path where the script is placed
        if not dirpath == ".":
            # change the dir seperator
            dirpath = dirpath.replace("\\", "/")

            currentDir = dirpath.split("/")[-1]
            # filter out the valid ending scss
            commentPrinted = False
            for file in files:
                # if there is a file with more dots just focus on the last part
                fileEnding = file.split(".")[-1]
                if fileEnding in valid_file_endings:
                    if not commentPrinted:
                        print("/* {0} */".format(currentDir), file = scssFile)
                        commentPrinted = True
                    print("@import '{0}/{1}';".format(dirpath, file.split(".")[0][1:]), file = scssFile)

an example of an output file:

/* abstract */
@import './abstract/colors';
/* base */
@import './base/base';
/* components */
@import './components/audioPlayer';
@import './components/cardLayouter';
@import './components/content';

If you want to add a photo rotate button that'll keep rotating the photo in 90 degree increments, here you go. (finalImage is a UIImage that's already been created elsewhere.)

- (void)rotatePhoto {
    UIImage *rotatedImage;

    if (finalImage.imageOrientation == UIImageOrientationRight)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationDown];
    else if (finalImage.imageOrientation == UIImageOrientationDown)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationLeft];
    else if (finalImage.imageOrientation == UIImageOrientationLeft)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationUp];
    else
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                                     scale: 1.0
                                               orientation: UIImageOrientationRight];
    finalImage = rotatedImage;
}

A slightly other way of iterating through each column of each line of a CSV-file would be

$path = "d:\scratch\export.csv"
$csv = Import-Csv -path $path

foreach($line in $csv)
{ 
    $properties = $line | Get-Member -MemberType Properties
    for($i=0; $i -lt $properties.Count;$i++)
    {
        $column = $properties[$i]
        $columnvalue = $line | Select -ExpandProperty $column.Name

        # doSomething $column.Name $columnvalue 
        # doSomething $i $columnvalue 
    }
} 

so you have the choice: you can use either $column.Name to get the name of the column, or $i to get the number of the column

If you don't need the seeding capability just use Math.random() and build helper functions around it (eg. randRange(start, end)).

I'm not sure what RNG you're using, but it's best to know and document it so you're aware of its characteristics and limitations.

Like Starkii said, Mersenne Twister is a good PRNG, but it isn't easy to implement. If you want to do it yourself try implementing a LCG - it's very easy, has decent randomness qualities (not as good as Mersenne Twister), and you can use some of the popular constants.

Mini snippet:

var speedtest = {};
function speedTest_start(name) { speedtest[name]= +new Date(); }
function speedTest_stop(name) { return +new Date() - speedtest[name] + (delete 
speedtest[name]?0:0); }

use like:

speedTest_start("test1");

// ... some code

speedTest_stop("test1");
// returns the time duration in ms

Also more tests possible:

speedTest_start("whole");

// ... some code

speedTest_start("part");

// ... some code

speedTest_stop("part");
// returns the time duration in ms of "part"

// ... some code

speedTest_stop("whole");
// returns the time duration in ms of "whole"

A keystore needs a keystore file. The KeyStore class needs a FileInputStream. But if you supply null (instead of FileInputStream instance) an empty keystore will be loaded. Once you create a keystore, you can verify its integrity using keytool.

Following code creates an empty keystore with empty password

  KeyStore ks2 = KeyStore.getInstance("jks");
  ks2.load(null,"".toCharArray());
  FileOutputStream out = new FileOutputStream("C:\\mykeytore.keystore");
  ks2.store(out, "".toCharArray());

Once you have the keystore, importing certificate is very easy. Checkout this link for the sample code.

String strJson="{\"Employee\":
[{\"id\":\"101\",\"name\":\"Pushkar\",\"salary\":\"5000\"},
{\"id\":\"102\",\"name\":\"Rahul\",\"salary\":\"4000\"},
{\"id\":\"103\",\"name\":\"tanveer\",\"salary\":\"56678\"}]}";

This is an example of a JSON string with Employee as object, then multiple strings and values in an array as a reference to @cregox...

A bit complicated but can explain a lot in a single JSON string.

Yes, it's possible. But first read, "What happens when I change my username?"

To change your username, click your profile picture in the top right corner, then click Settings. On the left side, click Account. Then click Change username.

Your question is difficult to understand, but if you want to select the numbers from 1 to 100, then this should do the trick:

Select Rownum r
From dual
Connect By Rownum <= 100

Have you tried to access your page by typing "http://localhost:8012" (after restarting the apache)?

This is an example using the Expr() Class - I needed this too some days ago and it took me some time to find out what is the exact syntax and way of usage:

/**
 * fetches Products that are more expansive than the given price
 * 
 * @param int $price
 * @return array
 */
public function findProductsExpensiveThan($price)
{
  $em = $this->getEntityManager();
  $qb = $em->createQueryBuilder();

  $q  = $qb->select(array('p'))
           ->from('YourProductBundle:Product', 'p')
           ->where(
             $qb->expr()->gt('p.price', $price)
           )
           ->orderBy('p.price', 'DESC')
           ->getQuery();

  return $q->getResult();
}

I know there is already an answer to this but I just found a better solution using the variableWidth parameter, just set it to true in the settings of each breakpoint, like this:

$('#featured-articles').slick({
  arrows: true,
  autoplay: true,
  autoplaySpeed: 3000,
  dots: true,
  draggable: false,
  fade: true,
  infinite: false,
  responsive: [
  {
    breakpoint: 620,
    settings: {
        arrows: true,
        variableWidth: true
    }
  },
  {
    breakpoint: 345,
    settings: {
        arrows: true,
        variableWidth: true
    }
  }
  ]
});

I tried to add another join(), and it seems worked. Here is code

from threading import Thread
from time import sleep

def function01(arg,name):
    for i in range(arg):
        print(name,'i---->',i,'\n')
        print (name,"arg---->",arg,'\n')
        sleep(1)

def test01():
    thread1 = Thread(target = function01, args = (10,'thread1', ))
    thread1.start()
    thread2 = Thread(target = function01, args = (10,'thread2', ))
    thread2.start()
    thread1.join()
    thread2.join()
    print ("thread finished...exiting")

test01()

I'd suggest 3 things in the beginning of your script:

First, as already being said use environment:

#!/usr/bin/env python

Second, set your encoding:

# -*- coding: utf-8 -*-

Third, set some doc string:

"""This is a awesome
    python script!"""

And for sure I would use " " (4 spaces) for ident.
Final header will look like:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

"""This is a awesome
        python script!"""

Best wishes and happy coding.

ORDER BY is always last...

However, you need to pick the fields you ACTUALLY WANT then select only those and group by them. SELECT * and GROUP BY Email will give you RANDOM VALUES for all the fields but Email. Most RDBMS will not even allow you to do this because of the issues it creates, but MySQL is the exception.

SELECT Email, COUNT(*)
FROM user_log
GROUP BY Email
HAVING COUNT(*) > 1
ORDER BY UpdateDate DESC

By the time you say rate = lambda whatever... you've defeated the point of lambda and should just define a function. But, if you want a lambda, you can use 'and' and 'or'

lambda(T): (T>200) and (200*exp(-T)) or (400*exp(-T))

I don't think it's a good idea to process response received from the 3rd party server. This will only increase your proxy server's memory footprint. Further, it's the reason why your code is not working.

Instead try passing the response through to the client. Consider following snippet:

var http = require('http');

http.createServer(onRequest).listen(3000);

function onRequest(client_req, client_res) {
  console.log('serve: ' + client_req.url);

  var options = {
    hostname: 'www.google.com',
    port: 80,
    path: client_req.url,
    method: client_req.method,
    headers: client_req.headers
  };

  var proxy = http.request(options, function (res) {
    client_res.writeHead(res.statusCode, res.headers)
    res.pipe(client_res, {
      end: true
    });
  });

  client_req.pipe(proxy, {
    end: true
  });
}

It's quite easy. Just write this, for example:

npm install -g [email protected]

Or:

npm install -g npm@latest    // For the last stable version
npm install -g npm@next      // For the most recent release

MarkerImage has been deprecated for Icon

Until version 3.10 of the Google Maps JavaScript API, complex icons were defined as MarkerImage objects. The Icon object literal was added in 3.10, and replaces MarkerImage from version 3.11 onwards. Icon object literals support the same parameters as MarkerImage, allowing you to easily convert a MarkerImage to an Icon by removing the constructor, wrapping the previous parameters in {}'s, and adding the names of each parameter.

Phillippe's code would now be:

 var icon = {
     url: "../res/sit_marron.png", // url
     scaledSize: new google.maps.Size(width, height), // size
     origin: new google.maps.Point(0,0), // origin
     anchor: new google.maps.Point(anchor_left, anchor_top) // anchor 
 };

 position = new google.maps.LatLng(latitud,longitud)
 marker = new google.maps.Marker({
  position: position,
  map: map,
  icon: icon
 });

Set Cookie?

res.cookie('cookieName', 'cookieValue')

Read Cookie?

req.cookies

Demo

const express('express')
    , cookieParser = require('cookie-parser'); // in order to read cookie sent from client

app.get('/', (req,res)=>{

    // read cookies
    console.log(req.cookies) 

    let options = {
        maxAge: 1000 * 60 * 15, // would expire after 15 minutes
        httpOnly: true, // The cookie only accessible by the web server
        signed: true // Indicates if the cookie should be signed
    }

    // Set cookie
    res.cookie('cookieName', 'cookieValue', options) // options is optional
    res.send('')

})

Once you declare the type of a variable, you don't need to cast it to that same type. So you can write a=&b;. Finally, you declared c incorrectly. Since you assign it to be the address of a, where a is a pointer to int, you must declare it to be a pointer to a pointer to int.

#include <stdio.h>
int main(void)
{
    int b=10;
    int *a=&b;
    int **c=&a;
    printf("%d", **c);
    return 0;
} 

I know this is an ancient thread but I wanted to add a few nuances.

There are Maven artifacts, repository manager artifacts and then there are Maven Artifacts.

A Maven artifact is just as other commenters/responders say: it is a thing that is spat out by building a Maven project. That could be a .jar file, or a .war file, or a .zip file, or a .dll, or what have you.

A repository manager artifact is a thing that is, well, managed by a repository manager. A repository manager is basically a highly performant naming service for software executables and libraries. A repository manager doesn't care where its artifacts come from (maybe they came from a Maven build, or a local file, or an Ant build, or a by-hand compilation...).

A Maven Artifact is a Java class that represents the kind of "name" that gets dereferenced by a repository manager into a repository manager artifact. When used in this sense, an Artifact is just a glorified name made up of such parts as groupId, artifactId, version, scope, classifier and so on.

To put it all together:

• Your Maven project probably depends on several Artifacts by way of its <dependency> elements.
• Maven interacts with a repository manager to resolve those Artifacts into files by instructing the repository manager to send it some repository manager artifacts that correspond to the internal Artifacts.
• Finally, after resolution, Maven builds your project and produces a Maven artifact. You may choose to "turn this into" a repository manager artifact by, in turn, using whatever tool you like, sending it to the repository manager with enough coordinating information that other people can find it when they ask the repository manager for it.

Hope that helps.

Selenium WebDriver Java code:

Download Gecko Driver from https://github.com/mozilla/geckodriver/releases based on your platform. Extract it in a location by your choice. Write the following code:

System.setProperty("webdriver.gecko.driver", "D:/geckodriver-v0.16.1-win64/geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.lynda.com/Selenium-tutorials/Mastering-Selenium-Testing-Tools/521207-2.html");

technically, the answer is NO it is not possible to delete two objects AT THE SAME TIME. However, it IS possible to delete two objects in one line of beautiful python.

del (foo['bar'],foo['baz'])

will recusrively delete foo['bar'], then foo['baz']

I use Redgate backup pro 7 tools for this purpose. you can create mirror from backup file in create tile on other location. and can copy backup file after create on network and on host storage automatically.

Writing the whole path/directory eg. (for windows) C:\Programs\Python\Python36-32\Scripts\pip3.exe install mypackage. This worked well for me when I had trouble with pip.

While Shannon's answer is technically correct, it looks like overkill.

The simple solution is that you need to put your summation outside of the case statement. This should do the trick:

sum(CASE WHEN col1 > col2 THEN col3*col4 ELSE 0 END) AS some_product

Basically, your old code tells SQL to execute the sum(X*Y) for each line individually (leaving each line with its own answer that can't be grouped).

The code line I have written takes the sum product, which is what you want.

As of PowerShell 6.0, Split-Path has an -Extenstion parameter. This means you can do:

$path | Split-Path -Extension

or

Split-Path -Path $path -Extension

For $path = "test.txt" both versions will return .txt, inluding the full stop.

I created extension methods with a property that retrieves the connection string from configuration. This lets the callers not have to know anything about the connection, whether it's open or closed, etc. This method does limit you a bit since you're hiding some of the Dapper functionality, but in our fairly simple app it's worked fine for us, and if we needed more functionality from Dapper we could always add a new extension method that exposes it.

internal static string ConnectionString = new Configuration().ConnectionString;

    internal static IEnumerable<T> Query<T>(string sql, object param = null)
    {
        using (SqlConnection conn = new SqlConnection(ConnectionString))
        {
            conn.Open();
            return conn.Query<T>(sql, param);
        }
    }

    internal static int Execute(string sql, object param = null)
    {
        using (SqlConnection conn = new SqlConnection(ConnectionString))
        {
            conn.Open();
            return conn.Execute(sql, param);
        }
    }

Try this using apache commons:

String src = "Hello"; //This will work with any serialisable object
System.out.println(
            "Object Size:" + SerializationUtils.serialize((Serializable) src).length)

Set the upper date to date + 1 day, so in your case, set it to 2011-02-01.

Try interface{} instead. To cast back as slice, try

func foo(bar interface{}) {
    s := bar.([]string)
    // ...
}

In my situation I needed to answer some questions without Y or N but with text or blank. I found the best way to do this in my situation was to create a shellscript file. In my case I called it autocomplete.sh

I was needing to answer some questions for a doctrine schema exporter so my file looked like this.

-- This is an example only --

php vendor/bin/mysql-workbench-schema-export mysqlworkbenchfile.mwb ./doctrine << EOF
`#Export to Doctrine Annotation Format`                                     1
`#Would you like to change the setup configuration before exporting`        y
`#Log to console`                                                           y
`#Log file`                                                                 testing.log
`#Filename [%entity%.%extension%]`
`#Indentation [4]`
`#Use tabs [no]`
`#Eol delimeter (win, unix) [win]`
`#Backup existing file [yes]`
`#Add generator info as comment [yes]`
`#Skip plural name checking [no]`
`#Use logged storage [no]`
`#Sort tables and views [yes]`
`#Export only table categorized []`
`#Enhance many to many detection [yes]`
`#Skip many to many tables [yes]`
`#Bundle namespace []`
`#Entity namespace []`
`#Repository namespace []`
`#Use automatic repository [yes]`
`#Skip column with relation [no]`
`#Related var name format [%name%%related%]`
`#Nullable attribute (auto, always) [auto]`
`#Generated value strategy (auto, identity, sequence, table, none) [auto]`
`#Default cascade (persist, remove, detach, merge, all, refresh, ) [no]`
`#Use annotation prefix [ORM\]`
`#Skip getter and setter [no]`
`#Generate entity serialization [yes]`
`#Generate extendable entity [no]`                                          y
`#Quote identifier strategy (auto, always, none) [auto]`
`#Extends class []`
`#Property typehint [no]`
EOF

The thing I like about this strategy is you can comment what your answers are and using EOF a blank line is just that (the default answer). Turns out by the way this exporter tool has its own JSON counterpart for answering these questions, but I figured that out after I did this =).

to run the script simply be in the directory you want and run 'sh autocomplete.sh' in terminal.

In short by using << EOL & EOF in combination with Return Lines you can answer each question of the prompt as necessary. Each new line is a new answer.

My example just shows how this can be done with comments also using the ` character so you remember what each step is.

Note the other advantage of this method is you can answer with more then just Y or N ... in fact you can answer with blanks!

Hope this helps someone out.

Fast HTML Demo code: Based on what I know about SFML C++ graphics library:

Save this as an HTML file with UTF-8 Encoding and run it. Feel free to refactor, I just like using japanese variables because they are concise and don't take up much space

Rarely are you going to want to set ONE arbitrary pixel and display it on the screen. So use the

PutPix(x,y, r,g,b,a) 

method to draw numerous arbitrary pixels to a back-buffer. (cheap calls)

Then when ready to show, call the

Apply() 

method to display the changes. (expensive call)

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

Better way is to autowire with a constructor:

private final HttpServletRequest httpServletRequest;

public ClassConstructor(HttpServletRequest httpServletRequest){
      this.httpServletRequest = httpServletRequest;
}

The verbose option is handy, but if you want to see everything that curl does (including the HTTP body that is transmitted, and not just the headers), I suggest using one of the below options:

• --trace-ascii - # stdout
• --trace-ascii output_file.txt # file

I like this little plugin. It needs a bit more cross browser friendliness though.

To cut it short: There is absolutely no difference in doing this in JavaScript.

First of all, you can test it yourself:

• jsperf - is an excellent platform for all sorts of performance testing in JavaScript.

• http://jsperf.com/inc-vs-dec-2

Not only can you test and run any script in any JavaScript library, but you also have access to the whole bunch of previously written scripts, as well as the abilty to see differences between execution time in different browsers on different platforms.

So as far as you can see, there is no difference between performance in any environment.

If you want to improve performance of your script, things you can try to do:

1. Have a var a = array.length; statement so that you will not be calculating its value each time in the loop
2. Do loop unrolling http://en.wikipedia.org/wiki/Loop_unwinding

But you have to understand that the improvement you can gain will be so insignificant, that mostly you should not even care about it.

My own opinion why such a misconception (Dec vs Inc) appeared

A long, long time ago there was a common machine instruction, DSZ (Decrement and Skip on Zero). People who programmed in assembly language used this instruction to implement loops in order to save a register. Now this ancient facts are obsolete, and I am pretty sure you will not get any performance improvement in any language using this pseudo improvement.

I think the only way such knowledge can propagate in our time is when you read another's person code. See such a construction and ask why was it implemented and here the answer: "it improves performance because it compares to zero". You became bewildered of higher knowledge of your colleague and think to use it to be much smarter :-)

Following the documentation of fopen:

``a'' Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then cur- rent end of file, irrespective of any intervening fseek(3) or similar.

So if you pFile2=fopen("myfile2.txt", "a"); the stream is positioned at the end to append automatically. just do:

FILE *pFile;
FILE *pFile2;
char buffer[256];

pFile=fopen("myfile.txt", "r");
pFile2=fopen("myfile2.txt", "a");
if(pFile==NULL) {
    perror("Error opening file.");
}
else {
    while(fgets(buffer, sizeof(buffer), pFile)) {
        fprintf(pFile2, "%s", buffer);
    }
}
fclose(pFile);
fclose(pFile2);

If you are at a certain branch mybranch, just go ahead and git checkout commit_hash. Then you can return to your branch by git checkout mybranch. I had the same game bisecting a bug today :) Also, you should know about git bisect.

If you have more than one join you could use comma separated USING statements:

DELETE 
FROM 
      AAA AS a 
USING 
      BBB AS b,
      CCC AS c
WHERE 
      a.id = b.id 
  AND a.id = c.id
  AND a.uid = 12345 
  AND c.gid = 's434sd4'

Reference

It really depends on what functions you're using to plot the lines, but try see if the on you're using takes an alpha value and set it to something like 0.5. If that doesn't work, try get the line objects and set their alpha values directly.

Here is a working solution:

#include <stdio.h>
#include <string.h>

int main(int argc, char** argv) 
{
      char str1[16];
      char str2[16];
      strcpy(str1, "sssss");
      strcpy(str2, "kkkk");
      strcat(str1, str2);
      printf("%s", str1);
      return 0;
}

Output:

ssssskkkk

You have to allocate memory for your strings. In the above code, I declare str1 and str2 as character arrays containing 16 characters. I used strcpy to copy characters of string literals into them, and strcat to append the characters of str2 to the end of str1. Here is how these character arrays look like during the execution of the program:

After declaration (both are empty): 
str1: [][][][][][][][][][][][][][][][][][][][] 
str2: [][][][][][][][][][][][][][][][][][][][]

After calling strcpy (\0 is the string terminator zero byte): 
str1: [s][s][s][s][s][\0][][][][][][][][][][][][][][] 
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

After calling strcat: 
str1: [s][s][s][s][s][k][k][k][k][\0][][][][][][][][][][] 
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

To convert tuples to list

(Commas were missing between the tuples in the given question, it was added to prevent error message)

Method 1:

level1 = (
     (1,1,1,1,1,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,1,1,1,1,1))

level1 = [list(row) for row in level1]

print(level1)

Method 2:

level1 = map(list,level1)

print(list(level1))

Method 1 took --- 0.0019991397857666016 seconds ---

Method 2 took --- 0.0010001659393310547 seconds ---

Make sure to select "All" to find the enable bitcode build settings:

echo date("l M j, Y",$res1['timep']);
This is really good for converting a unix timestamp to a readable date along with day. Example: Thursday Jul 7, 2016

I agree with the other answers that point you to app.config. However, rather than reading values directly from app.config, you should create a utility class (AppSettings is the name I use) to read them and expose them as properties. The AppSettings class can be used to aggregate settings from several stores, such as values from app.config and application version info from the assembly (AssemblyVersion and AssemblyFileVersion).

Perhaps you're not disposing of the previous connection/ result classes from the previous run which means their still hanging around in memory.

you can try this

using System.Windows.Forms; // u need this to include.

MethodInvoker updateIt = delegate
                {
                    this.label1.Text = "Started...";
                };
this.label1.BeginInvoke(updateIt);

See if it works.

If you do not want to use numpy,

sorted(range(len(seq)), key=seq.__getitem__)

is fastest, as demonstrated here.

It's ok to pass an array - in fact it amounts to the same thing

String.format("%s %s", "hello", "world!");

is the same as

String.format("%s %s", new Object[] { "hello", "world!"});

It's just syntactic sugar - the compiler converts the first one into the second, since the underlying method is expecting an array for the vararg parameter.

See

• Varargs - J2SE 1.5 Documentation

take a look at the plyr package. Specifically, ddply

ddply(df, .(group), summarise, mean=mean(dt), sum=sum(dt))

Here I want to pad my number with 4 digit. For instance, if it is 1 then it should show as 0001, if it 11 it should show as 0011.

Below is the code that accomplishes this:

reciptno=1; // Pass only integer.

string formatted = string.Format("{0:0000}", reciptno);

TxtRecNo.Text = formatted; // Output=0001

I implemented this code to generate money receipt number for a PDF file.

The trick to make infinity's answer work without the flickering is to put the scroll-check on another div then the one you want to have fixed.

Derived from the code viixii.com uses I ended up using this:

function sticky_relocate() {
    var window_top = $(window).scrollTop();
    var div_top = $('#sticky-anchor').offset().top;
    if (window_top > div_top)
        $('#sticky-element').addClass('sticky');
    else
        $('#sticky-element').removeClass('sticky');
}

$(function() {
    $(window).scroll(sticky_relocate);
    sticky_relocate();
});

This way the function is only called once the sticky-anchor is reached and thus won't be removing and adding the '.sticky' class on every scroll event.

Now it adds the sticky class when the sticky-anchor reaches the top and removes it once the sticky-anchor return into view.

Just place an empty div with a class acting like an anchor just above the element you want to have fixed.

Like so:

<div id="sticky-anchor"></div>
<div id="sticky-element">Your sticky content</div>

All credit for the code goes to viixii.com

For some - possibly valid - reason the url was encoded twice. %25 is the urlencoded % sign. So the original url looked like:

http://server.com/my path/

Then it got urlencoded once:

http://server.com/my%20path/

and twice:

http://server.com/my%2520path/

So you should do no urlencoding - in your case - as other components seems to to that already for you. Use simply a space

Use simple FileStream.Read then print it with Convert.ToString(b, 2)

Just want to add my experience and answer to this.
Note: It only works when you have a pre-defined table and a tr with ths, but are loading in your rows (for example via AJAX) dynamically.

In this case you can count the number of th's there are in your first header row, and use that to span the whole column.

This can be needed when you want to relay a message when no results have been found.

Something like this in jQuery, where table is your input table:

var trs = $(table).find("tr");
var numberColumns = 999;
if (trs.length === 1) {
    //Assume having one row means that there is a header
    var headerColumns = $(trs).find("th").length;
    if (headerColumns > 0) {
        numberColumns = headerColumns;
    }
}

Better and easier git log by making an alias. Paste the code below to terminal just once for one session. Paste the code to zshrc or bash profile to make it persistant.

git config --global alias.lg "log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit"

Output

git lg

Output changed lines

git lg -p

Alternatively (recommended)
Paste this code to global .gitconfig file

[alias]
  lg = log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit

Refer this question: The mouseEvent.offsetX I am getting is much larger than actual canvas size .I have given a function there which will exactly suit in your situation

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

I'd just like to add to the very helpful answer from Kurt Pfeifle - there is now a Python wrapper for Tabula, and this seems to work very well so far: https://github.com/chezou/tabula-py

This will convert your PDF table to a Pandas data frame. You can also set the area in x,y co-ordinates which is obviously very handy for irregular data.

If you know which dict in the list has the key you're looking for, then you already have the solution (as presented by Matt and Ignacio). However, if you don't know which dict has this key, then you could do this:

def getValueOf(k, L):
    for d in L:
        if k in d:
            return d[k]

If you had the problem, opened SDK manager, installed the requested updates, returned to Android Studio and had the problem again, IT IS RECOMMENDED TO RESTART ANDROID STUDIO befor trying anything else.

Gradle will run automatically and chances are that your problem will be over. You will very possibly be told install the appropriate SDK TOOLS package, which is found in your SDK MANAGER under the second tab (sdk's are not the same as sdk tools, they are complementary packages).

You don't even need to hunt the tools package, if you click on the link under the error message, Android Studio should call SDK Manager to install the package automatically.

Restart Android Studio again and you should be up and running much faster than if you attempted workarounds.

RULE OF THUMB> restart your application before messing with options and configurations.

As of Android 2.1, Android only supports a single camera in its SDK. It is likely that this will be added in a future Android release.

Before installing libgtk2.0-dev and pkg-config or libqt4-dev. Make sure that you have uninstalled opencv. You can confirm this by running import cv2 on your python shell. If it fails, then install the needed packages and re-run cmake .

I've developed a dotnet library that might come in useful. I have fixed the problem of never getting all of the data if it exceeds the buffer, which many posts have discounted. Still some problems with the solution but works descently well https://github.com/NicholasLKSharp/DotNet-TCP-Communication

typeof is applied to a name of a type or generic type parameter known at compile time (given as identifier, not as string). GetType is called on an object at runtime. In both cases the result is an object of the type System.Type containing meta-information on a type.

Example where compile-time and run-time types are equal

string s = "hello";

Type t1 = typeof(string);
Type t2 = s.GetType();

t1 == t2 ==> true

Example where compile-time and run-time types are different

object obj = "hello";

Type t1 = typeof(object); // ==> object
Type t2 = obj.GetType();  // ==> string!

t1 == t2 ==> false

i.e., the compile time type (static type) of the variable obj is not the same as the runtime type of the object referenced by obj.

Testing types

If, however, you only want to know whether mycontrol is a TextBox then you can simply test

if (mycontrol is TextBox)

Note that this is not completely equivalent to

if (mycontrol.GetType() == typeof(TextBox))    

because mycontrol could have a type that is derived from TextBox. In that case the first comparison yields true and the second false! The first and easier variant is OK in most cases, since a control derived from TextBox inherits everything that TextBox has, probably adds more to it and is therefore assignment compatible to TextBox.

public class MySpecializedTextBox : TextBox
{
}

MySpecializedTextBox specialized = new MySpecializedTextBox();
if (specialized is TextBox)       ==> true

if (specialized.GetType() == typeof(TextBox))        ==> false

Casting

If you have the following test followed by a cast and T is nullable ...

if (obj is T) {
    T x = (T)obj; // The casting tests, whether obj is T again!
    ...
}

... you can change it to ...

T x = obj as T;
if (x != null) {
    ...
}

Testing whether a value is of a given type and casting (which involves this same test again) can both be time consuming for long inheritance chains. Using the as operator followed by a test for null is more performing.

Starting with C# 7.0 you can simplify the code by using pattern matching:

if (obj is T t) {
    // t is a variable of type T having a non-null value.
    ...
}

Btw.: this works for value types as well. Very handy for testing and unboxing. Note that you cannot test for nullable value types:

if (o is int? ni) ===> does NOT compile!

This is because either the value is null or it is an int. This works for int? o as well as for object o = new Nullable<int>(x);:

if (o is int i) ===> OK!

I like it, because it eliminates the need to access the Nullable<T>.Value property.

__construct simply initiates a class. Suppose you have the following code;

Class Person { 

 function __construct() {
   echo 'Hello';
  }

}

$person = new Person();

//the result 'Hello' will be shown.

We did not create another function to echo the word 'Hello'. It simply shows that the keyword __construct is quite useful in initiating a class or an object.

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

You can use below code

$.when( Typer() ).done(function() {
       playBGM();
});

What you may want to do is include a script on all pages that does the following ... 1. find the youtube-iframe : searching for it by width and height by title or by finding www.youtube.com in its source. You can do that by ... - looping through the window.frames by a for-in loop and then filter out by the properties

1. inject jscript in the iframe of the current page adding the onYoutubePlayerReady must-include-function http://shazwazza.com/post/Injecting-JavaScript-into-other-frames.aspx

2. Add the event listeners etc..

Hope this helps

Judging by the desktop folder location you are using Windows. The command in Windows would be:

IMPORTANT Gotcha for using .contains() on a Collection of Objects, such as Domains. If the Domain declaration contains a EqualsAndHashCode, or some other equals() implementation to determine if those Ojbects are equal, and you've set it like this...

import groovy.transform.EqualsAndHashCode
@EqualsAndHashCode(includes = "settingNameId, value")

then the .contains(myObjectToCompareTo) will evaluate the data in myObjectToCompareTo with the data for each Object instance in the Collection. So, if your equals method isn't up to snuff, as mine was not, you might see unexpected results.

you may use opacity:0.5;//what ever you wish between 0 and 1 for this.

working Fiddle

In terms of pattern interpretation, there's no difference between the following forms:

• /pattern/
• new RegExp("pattern")

If you want to replace a literal string using the replace method, I think you can just pass a string instead of a regexp to replace.

Otherwise, you'd have to escape any regexp special characters in the pattern first - maybe like so:

function reEscape(s) {
    return s.replace(/([.*+?^$|(){}\[\]])/mg, "\\$1");
}

// ...

var re = new RegExp(reEscape(pattern), "mg");
this.markup = this.markup.replace(re, value);

For those who want isoWeek to be the default you can modify moment's behaviour as such:

const moment = require('moment');
const proto = Object.getPrototypeOf(moment());

const {startOf, endOf} = proto;
proto.startOf = function(period) {
  if (period === 'week') {
    period = 'isoWeek';
  }
  return startOf.call(this, period);
};
proto.endOf = function(period) {
  if (period === 'week') {
    period = 'isoWeek';
  }
  return endOf.call(this, period);
};

Now you can simply use someDate.startOf('week') without worrying you'll get sunday or having to think about whether to use isoweek or isoWeek etc.

Plus you can store this in a variable like const period = 'week' and use it safely in subtract() or add() operations, e.g. moment().subtract(1, period).startOf(period);. This won't work with period being isoWeek.
