Programs & Examples On #Linear regression

Scikit-learn is a machine learning library for Python which can do this job for you. Just import sklearn.linear_model module into your script.

Find the code template for Multiple Linear Regression using sklearn in Python:

import numpy as np
import matplotlib.pyplot as plt #to plot visualizations
import pandas as pd

# Importing the dataset
df = pd.read_csv(<Your-dataset-path>)
# Assigning feature and target variables
X = df.iloc[:,:-1]
y = df.iloc[:,-1]

# Use label encoders, if you have any categorical variable
from sklearn.preprocessing import LabelEncoder
labelencoder = LabelEncoder()
X['<column-name>'] = labelencoder.fit_transform(X['<column-name>'])

from sklearn.preprocessing import OneHotEncoder
onehotencoder = OneHotEncoder(categorical_features = ['<index-value>'])
X = onehotencoder.fit_transform(X).toarray()

# Avoiding the dummy variable trap
X = X[:,1:] # Usually done by the algorithm itself

#Spliting the data into test and train set
from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X,y, random_state = 0, test_size = 0.2)

# Fitting the model
from sklearn.linear_model import LinearRegression
regressor = LinearRegression()
regressor.fit(X_train, y_train)

# Predicting the test set results
y_pred = regressor.predict(X_test)

That's it. You can use this code as a template for implementing Multiple Linear Regression in any dataset. For a better understanding with an example, Visit: Linear Regression with an example

The sklearn.metrics.accuracy_score(y_true, y_pred) method defines y_pred as:

y_pred : 1d array-like, or label indicator array / sparse matrix. Predicted labels, as returned by a classifier.

Which means y_pred has to be an array of 1's or 0's (predicated labels). They should not be probabilities.

The predicated labels (1's and 0's) and/or predicted probabilites can be generated using the LinearRegression() model's methods predict() and predict_proba() respectively.

1. Generate predicted labels:

LR = linear_model.LinearRegression()
y_preds=LR.predict(X_test)
print(y_preds)

output:

[1 1 0 1]

y_preds can now be used for the accuracy_score() method: accuracy_score(y_true, y_pred)

2. Generate probabilities for labels:

Some metrics such as 'precision_recall_curve(y_true, probas_pred)' require probabilities, which can be generated as follows:

LR = linear_model.LinearRegression()
y_preds=LR.predict_proba(X_test)
print(y_preds)

output:

[0.87812372 0.77490434 0.30319547 0.84999743]

I know this is an old question, but I had a similar issue and found that:

lm(x ~ y + relevel(b, ref = "3")) 

does exactly what you asked.

I found this function on a blog

 ggplotRegression <- function (fit) {

    `require(ggplot2)

    ggplot(fit$model, aes_string(x = names(fit$model)[2], y = names(fit$model)[1])) + 
      geom_point() +
      stat_smooth(method = "lm", col = "red") +
      labs(title = paste("Adj R2 = ",signif(summary(fit)$adj.r.squared, 5),
                         "Intercept =",signif(fit$coef[[1]],5 ),
                         " Slope =",signif(fit$coef[[2]], 5),
                         " P =",signif(summary(fit)$coef[2,4], 5)))
    }`

once you loaded the function you could simply

ggplotRegression(fit)

you can also go for ggplotregression( y ~ x + z + Q, data)

Hope this helps.

run both:

sess.run(tf.global_variables_initializer())

sess.run(tf.local_variables_initializer())

Following @thomas-jungblut implementation in python, i did the same for Octave. If you find something wrong please let me know and i will fix+update.

Data comes from a txt file with the following rows:

1 10 1000
2 20 2500
3 25 3500
4 40 5500
5 60 6200

think about it as a very rough sample for features [number of bedrooms] [mts2] and last column [rent price] which is what we want to predict.

Here is the Octave implementation:

%
% Linear Regression with multiple variables
%

% Alpha for learning curve
alphaNum = 0.0005;

% Number of features
n = 2;

% Number of iterations for Gradient Descent algorithm
iterations = 10000

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% No need to update after here
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

DATA = load('CHANGE_WITH_DATA_FILE_PATH');

% Initial theta values
theta = ones(n + 1, 1);

% Number of training samples
m = length(DATA(:, 1));

% X with one mor column (x0 filled with '1's)
X = ones(m, 1);
for i = 1:n
  X = [X, DATA(:,i)];
endfor

% Expected data must go always in the last column  
y = DATA(:, n + 1)

function gradientDescent(x, y, theta, alphaNum, iterations)
  iterations = [];
  costs = [];

  m = length(y);

  for iteration = 1:10000
    hypothesis = x * theta;

    loss = hypothesis - y;

    % J(theta)    
    cost = sum(loss.^2) / (2 * m);

    % Save for the graphic to see if the algorithm did work
    iterations = [iterations, iteration];
    costs = [costs, cost];

    gradient = (x' * loss) / m; % /m is for the average

    theta = theta - (alphaNum * gradient);
  endfor    

  % Show final theta values
  display(theta)

  % Show J(theta) graphic evolution to check it worked, tendency must be zero
  plot(iterations, costs);

endfunction

% Execute gradient descent
gradientDescent(X, y, theta, alphaNum, iterations);

arange generates lists (well, numpy arrays); type help(np.arange) for the details. You don't need to call it on existing lists.

>>> x = [1,2,3,4]
>>> y = [3,5,7,9] 
>>> 
>>> m,b = np.polyfit(x, y, 1)
>>> m
2.0000000000000009
>>> b
0.99999999999999833

I should add that I tend to use poly1d here rather than write out "m*x+b" and the higher-order equivalents, so my version of your code would look something like this:

import numpy as np
import matplotlib.pyplot as plt

x = [1,2,3,4]
y = [3,5,7,10] # 10, not 9, so the fit isn't perfect

coef = np.polyfit(x,y,1)
poly1d_fn = np.poly1d(coef) 
# poly1d_fn is now a function which takes in x and returns an estimate for y

plt.plot(x,y, 'yo', x, poly1d_fn(x), '--k')
plt.xlim(0, 5)
plt.ylim(0, 12)

I included a statistics stat_poly_eq() in my package ggpmisc that allows this answer:

library(ggplot2)
library(ggpmisc)
df <- data.frame(x = c(1:100))
df$y <- 2 + 3 * df$x + rnorm(100, sd = 40)
my.formula <- y ~ x
p <- ggplot(data = df, aes(x = x, y = y)) +
   geom_smooth(method = "lm", se=FALSE, color="black", formula = my.formula) +
   stat_poly_eq(formula = my.formula, 
                aes(label = paste(..eq.label.., ..rr.label.., sep = "~~~")), 
                parse = TRUE) +         
   geom_point()
p

This statistic works with any polynomial with no missing terms, and hopefully has enough flexibility to be generally useful. The R^2 or adjusted R^2 labels can be used with any model formula fitted with lm(). Being a ggplot statistic it behaves as expected both with groups and facets.

The 'ggpmisc' package is available through CRAN.

Version 0.2.6 was just accepted to CRAN.

It addresses comments by @shabbychef and @MYaseen208.

@MYaseen208 this shows how to add a hat.

library(ggplot2)
library(ggpmisc)
df <- data.frame(x = c(1:100))
df$y <- 2 + 3 * df$x + rnorm(100, sd = 40)
my.formula <- y ~ x
p <- ggplot(data = df, aes(x = x, y = y)) +
   geom_smooth(method = "lm", se=FALSE, color="black", formula = my.formula) +
   stat_poly_eq(formula = my.formula,
                eq.with.lhs = "italic(hat(y))~`=`~",
                aes(label = paste(..eq.label.., ..rr.label.., sep = "~~~")), 
                parse = TRUE) +         
   geom_point()
p

@shabbychef Now it is possible to match the variables in the equation to those used for the axis-labels. To replace the x with say z and y with h one would use:

p <- ggplot(data = df, aes(x = x, y = y)) +
   geom_smooth(method = "lm", se=FALSE, color="black", formula = my.formula) +
   stat_poly_eq(formula = my.formula,
                eq.with.lhs = "italic(h)~`=`~",
                eq.x.rhs = "~italic(z)",
                aes(label = ..eq.label..), 
                parse = TRUE) + 
   labs(x = expression(italic(z)), y = expression(italic(h))) +          
   geom_point()
p

Being these normal R parsed expressions greek letters can now also be used both in the lhs and rhs of the equation.

[2017-03-08] @elarry Edit to more precisely address the original question, showing how to add a comma between the equation- and R2-labels.

p <- ggplot(data = df, aes(x = x, y = y)) +
  geom_smooth(method = "lm", se=FALSE, color="black", formula = my.formula) +
  stat_poly_eq(formula = my.formula,
               eq.with.lhs = "italic(hat(y))~`=`~",
               aes(label = paste(..eq.label.., ..rr.label.., sep = "*plain(\",\")~")), 
               parse = TRUE) +         
  geom_point()
p

[2019-10-20] @helen.h I give below examples of use of stat_poly_eq() with grouping.

library(ggpmisc)
df <- data.frame(x = c(1:100))
df$y <- 20 * c(0, 1) + 3 * df$x + rnorm(100, sd = 40)
df$group <- factor(rep(c("A", "B"), 50))
my.formula <- y ~ x
p <- ggplot(data = df, aes(x = x, y = y, colour = group)) +
  geom_smooth(method = "lm", se=FALSE, formula = my.formula) +
  stat_poly_eq(formula = my.formula, 
               aes(label = paste(..eq.label.., ..rr.label.., sep = "~~~")), 
               parse = TRUE) +         
  geom_point()
p

p <- ggplot(data = df, aes(x = x, y = y, linetype = group)) +
  geom_smooth(method = "lm", se=FALSE, formula = my.formula) +
  stat_poly_eq(formula = my.formula, 
               aes(label = paste(..eq.label.., ..rr.label.., sep = "~~~")), 
               parse = TRUE) +         
  geom_point()
p

[2020-01-21] @Herman It may be a bit counter-intuitive at first sight, but to obtain a single equation when using grouping one needs to follow the grammar of graphics. Either restrict the mapping that creates the grouping to individual layers (shown below) or keep the default mapping and override it with a constant value in the layer where you do not want the grouping (e.g. colour = "black").

Continuing from previous example.

p <- ggplot(data = df, aes(x = x, y = y)) +
  geom_smooth(method = "lm", se=FALSE, formula = my.formula) +
  stat_poly_eq(formula = my.formula, 
               aes(label = paste(..eq.label.., ..rr.label.., sep = "~~~")), 
               parse = TRUE) +         
  geom_point(aes(colour = group))
p

[2020-01-22] For the sake of completeness an example with facets, demonstrating that also in this case the expectations of the grammar of graphics are fulfilled.

library(ggpmisc)
df <- data.frame(x = c(1:100))
df$y <- 20 * c(0, 1) + 3 * df$x + rnorm(100, sd = 40)
df$group <- factor(rep(c("A", "B"), 50))
my.formula <- y ~ x

p <- ggplot(data = df, aes(x = x, y = y)) +
  geom_smooth(method = "lm", se=FALSE, formula = my.formula) +
  stat_poly_eq(formula = my.formula, 
               aes(label = paste(..eq.label.., ..rr.label.., sep = "~~~")), 
               parse = TRUE) +         
  geom_point() +
  facet_wrap(~group)
p

Let's fit the model:

> library(ISwR)
> fit <- lm(metabolic.rate ~ body.weight, rmr)
> summary(fit)

Call:
lm(formula = metabolic.rate ~ body.weight, data = rmr)

Residuals:
    Min      1Q  Median      3Q     Max 
-245.74 -113.99  -32.05  104.96  484.81 

Coefficients:
            Estimate Std. Error t value Pr(>|t|)    
(Intercept) 811.2267    76.9755  10.539 2.29e-13 ***
body.weight   7.0595     0.9776   7.221 7.03e-09 ***
---
Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 

Residual standard error: 157.9 on 42 degrees of freedom
Multiple R-squared: 0.5539, Adjusted R-squared: 0.5433 
F-statistic: 52.15 on 1 and 42 DF,  p-value: 7.025e-09 

The 95% confidence interval for the slope is the estimated coefficient (7.0595) ± two standard errors (0.9776).

This can be computed using confint:

> confint(fit, 'body.weight', level=0.95)
               2.5 % 97.5 %
body.weight 5.086656 9.0324

The basic difference between Linear Regression and Logistic Regression is : Linear Regression is used to predict a continuous or numerical value but when we are looking for predicting a value that is categorical Logistic Regression come into picture.

Logistic Regression is used for binary classification.

Here's a linearization option on simple data that uses tools from scikit learn.

Given

import numpy as np

import matplotlib.pyplot as plt

from sklearn.linear_model import LinearRegression
from sklearn.preprocessing import FunctionTransformer


np.random.seed(123)

# General Functions
def func_exp(x, a, b, c):
    """Return values from a general exponential function."""
    return a * np.exp(b * x) + c


def func_log(x, a, b, c):
    """Return values from a general log function."""
    return a * np.log(b * x) + c


# Helper
def generate_data(func, *args, jitter=0):
    """Return a tuple of arrays with random data along a general function."""
    xs = np.linspace(1, 5, 50)
    ys = func(xs, *args)
    noise = jitter * np.random.normal(size=len(xs)) + jitter
    xs = xs.reshape(-1, 1)                                  # xs[:, np.newaxis]
    ys = (ys + noise).reshape(-1, 1)
    return xs, ys

transformer = FunctionTransformer(np.log, validate=True)

Code

Fit exponential data

# Data
x_samp, y_samp = generate_data(func_exp, 2.5, 1.2, 0.7, jitter=3)
y_trans = transformer.fit_transform(y_samp)             # 1

# Regression
regressor = LinearRegression()
results = regressor.fit(x_samp, y_trans)                # 2
model = results.predict
y_fit = model(x_samp)

# Visualization
plt.scatter(x_samp, y_samp)
plt.plot(x_samp, np.exp(y_fit), "k--", label="Fit")     # 3
plt.title("Exponential Fit")

Fit log data

# Data
x_samp, y_samp = generate_data(func_log, 2.5, 1.2, 0.7, jitter=0.15)
x_trans = transformer.fit_transform(x_samp)             # 1

# Regression
regressor = LinearRegression()
results = regressor.fit(x_trans, y_samp)                # 2
model = results.predict
y_fit = model(x_trans)

# Visualization
plt.scatter(x_samp, y_samp)
plt.plot(x_samp, y_fit, "k--", label="Fit")             # 3
plt.title("Logarithmic Fit")

Details

General Steps

1. Apply a log operation to data values (x, y or both)
2. Regress the data to a linearized model
3. Plot by "reversing" any log operations (with np.exp()) and fit to original data

Assuming our data follows an exponential trend, a general equation⁺ may be:

We can linearize the latter equation (e.g. y = intercept + slope * x) by taking the log:

Given a linearized equation⁺⁺ and the regression parameters, we could calculate:

• A via intercept (ln(A))
• B via slope (B)

Summary of Linearization Techniques

Relationship |  Example   |     General Eqn.     |  Altered Var.  |        Linearized Eqn.  
-------------|------------|----------------------|----------------|------------------------------------------
Linear       | x          | y =     B * x    + C | -              |        y =   C    + B * x
Logarithmic  | log(x)     | y = A * log(B*x) + C | log(x)         |        y =   C    + A * (log(B) + log(x))
Exponential  | 2**x, e**x | y = A * exp(B*x) + C | log(y)         | log(y-C) = log(A) + B * x
Power        | x**2       | y =     B * x**N + C | log(x), log(y) | log(y-C) = log(B) + N * log(x)

_{⁺Note: linearizing exponential functions works best when the noise is small and C=0. Use with caution.}

_{⁺⁺Note: while altering x data helps linearize exponential data, altering y data helps linearize log data.}

seems you need to link with the obj file that implements tolayer5()

Update: your function declaration doesn't match the implementation:

      void tolayer5(int AorB, struct msg msgReceived)
      void tolayer5(int, char data[])

So compiler would treat them as two different functions (you are using c++). and it cannot find the implementation for the one you called in main().

I know this is an old question, but I had a similar issue and found that:

lm(x ~ y + relevel(b, ref = "3")) 

does exactly what you asked.

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

http://www.coderanch.com/t/515475/JDBC/databases/sql-insert-statement-giving-sqlcode

var Dictionary = {
  If: {
    you: {
      can: '',
      make: ''
    },
    sense: ''
  },
  of: {
    the: {
      sentence: {
        it: '',
        worked: ''
      }
    }
  }
};

function Iterate(obj) {
  for (prop in obj) {
    if (obj.hasOwnProperty(prop) && isNaN(prop)) {
      console.log(prop + ': ' + obj[prop]);
      Iterate(obj[prop]);
    }
  }
}
Iterate(Dictionary);

You could also disinherit all transitions inside a containing element:

CSS:

.noTrans *{
-moz-transition: none;
-webkit-transition: none;
-o-transition: color 0 ease-in;
transition: none;
}

HTML:

<a href="#">Content</a>
<a href="#">Content</a>
<div class="noTrans">
<a href="#">Content</a>
</div>
<a href="#">Content</a>

Two solutions: 1- if the type of the target column is [nvarchar] it should be change to [varchar]

2- Add a "Derived Column" component to the SSIS package and add a new column with the following expression:
(DT_WSTR, «length») [ColumnName]

Length is the length of the column in the target table and ColumnName is the name of the column in the target table. finally at the mapping part you should use this new added column instead of the original column.

Some other options, just for reference

-10.days.ago
# Available in Rails 4
DateTime.now.days_ago(-10)

Just list out all options I know:

[1] Time.now + 10.days
[2] 10.days.from_now
[3] -10.days.ago
[4] DateTime.now.days_ago(-10)
[5] Date.today + 10

So now, what is the difference between them if we care about the timezone:

• [1, 4] With system timezone
• [2, 3] With config timezone of your Rails app
• [5] Date only no time included in result

You can also do it in code if you need more control, for example multiple colors and positioning. Here is my Kotlin snippet to create a drawable radial gradient:

object ShaderUtils {
    private class RadialShaderFactory(private val colors: IntArray, val positionX: Float,
                                      val positionY: Float, val size: Float): ShapeDrawable.ShaderFactory() {

        override fun resize(width: Int, height: Int): Shader {
            return RadialGradient(
                    width * positionX,
                    height * positionY,
                    minOf(width, height) * size,
                    colors,
                    null,
                    Shader.TileMode.CLAMP)
        }
    }

    fun radialGradientBackground(vararg colors: Int, positionX: Float = 0.5f, positionY: Float = 0.5f,
                                 size: Float = 1.0f): PaintDrawable {
        val radialGradientBackground = PaintDrawable()
        radialGradientBackground.shape = RectShape()
        radialGradientBackground.shaderFactory = RadialShaderFactory(colors, positionX, positionY, size)
        return radialGradientBackground
    }
}

Basic usage (but feel free to adjust with additional params):

view.background = ShaderUtils.radialGradientBackground(Color.TRANSPARENT, BLACK)

Just try this in razor

@{
    var selectList = new SelectList(
        new List<SelectListItem>
        {
            new SelectListItem {Text = "Google", Value = "Google"},
            new SelectListItem {Text = "Other", Value = "Other"},
        }, "Value", "Text");
}

and then

@Html.DropDownListFor(m => m.YourFieldName, selectList, "Default label", new { @class = "css-class" })

or

@Html.DropDownList("ddlDropDownList", selectList, "Default label", new { @class = "css-class" })

USE COUNT_STAR

LOGS= LOAD 'log';
LOGS_GROUP= GROUP LOGS ALL;
LOG_COUNT = FOREACH LOGS_GROUP GENERATE COUNT_STAR(LOGS);

try this

var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'url';    

document.getElementsByTagName('head')[0].appendChild(script);

Managing XSS requires multiple validations, data from the client side.

1. Input Validations (form validation) on the Server side. There are multiple ways of going about it. You can try JSR 303 bean validation(hibernate validator), or ESAPI Input Validation framework. Though I've not tried it myself (yet), there is an annotation that checks for safe html (@SafeHtml). You could in fact use Hibernate validator with Spring MVC for bean validations -> Ref
2. Escaping URL requests - For all your HTTP requests, use some sort of XSS filter. I've used the following for our web app and it takes care of cleaning up the HTTP URL request - http://www.servletsuite.com/servlets/xssflt.htm
3. Escaping data/html returned to the client (look above at @BalusC explanation).

They are formatting String. The Java specific syntax is given in java.util.Formatter.

The general syntax is as follows:

   %[argument_index$][flags][width][.precision]conversion

%02d performs decimal integer conversion d, formatted with zero padding (0 flag), with width 2. Thus, an int argument whose value is say 7, will be formatted into "07" as a String.

You may also see this formatting string in e.g. String.format.

Commonly used formats

These are just some commonly used formats and doesn't cover the syntax exhaustively.

Zero padding for numbers

System.out.printf("Agent %03d to the rescue!", 7);
// Agent 007 to the rescue!

Width for justification

You can use the - flag for left justification; otherwise it'll be right justification.

for (Map.Entry<Object,Object> prop : System.getProperties().entrySet()) {
    System.out.printf("%-30s : %50s%n", prop.getKey(), prop.getValue());
}

This prints something like:

java.version                   :                                 1.6.0_07
java.vm.name                   :               Java HotSpot(TM) Client VM
java.vm.vendor                 :                    Sun Microsystems Inc.
java.vm.specification.name     :       Java Virtual Machine Specification
java.runtime.name              :          Java(TM) SE Runtime Environment
java.vendor.url                :                     http://java.sun.com/

For more powerful message formatting, you can use java.text.MessageFormat. %n is the newline conversion (see below).

Hexadecimal conversion

System.out.println(Integer.toHexString(255));
// ff

System.out.printf("%d is %<08X", 255);
// 255 is 000000FF

Note that this also uses the < relative indexing (see below).

Floating point formatting

System.out.printf("%+,010.2f%n", 1234.567);
System.out.printf("%+,010.2f%n", -66.6666);
// +01,234.57
// -000066.67

For more powerful floating point formatting, use DecimalFormat instead.

%n for platform-specific line separator

System.out.printf("%s,%n%s%n", "Hello", "World");
// Hello,
// World

%% for an actual %-sign

System.out.printf("It's %s%% guaranteed!", 99.99);
// It's 99.99% guaranteed!

Note that the double literal 99.99 is autoboxed to Double, on which a string conversion using toString() is defined.

n$ for explicit argument indexing

System.out.printf("%1$s! %1$s %2$s! %1$s %2$s %3$s!",
    "Du", "hast", "mich"
);
// Du! Du hast! Du hast mich!

< for relative indexing

System.out.format("%s?! %<S?!?!?", "Who's your daddy");
// Who's your daddy?! WHO'S YOUR DADDY?!?!?

Please note that you should not use any png when you are testing this , first work with jpg .

$myImage = "images/logos/mylogo.jpg";  // this is where you get your Image

$pdf->Image($myImage, 5, $pdf->GetY(), 33.78);

You can use shell redirection while executing the python file:

python foo_bar.py > file

This will write all results being printed on stdout from the python source to file to the logfile.

Or if you want logging from within the script:

import sys

class Logger(object):
    def __init__(self):
        self.terminal = sys.stdout
        self.log = open("logfile.log", "a")

    def write(self, message):
        self.terminal.write(message)
        self.log.write(message)  

    def flush(self):
        #this flush method is needed for python 3 compatibility.
        #this handles the flush command by doing nothing.
        #you might want to specify some extra behavior here.
        pass    

sys.stdout = Logger()

Now you can use:

print "Hello"

This will write "Hello" to both stdout and the logfile

Kevlar is correct.

An alternative to a custom DLL is Lua Alien

If you happen to not have the image, download it via the SDK manager:

I struggled with this as well and found a simple pattern to isolate the test context after a cursory read of the @ComponentScan docs.

/**
* Type-safe alternative to {@link #basePackages} for specifying the packages
* to scan for annotated components. The package of each class specified will be scanned.
* Consider creating a special no-op marker class or interface in each package
* that serves no purpose other than being referenced by this attribute.
*/
Class<?>[] basePackageClasses() default {};

1. Create a package for your spring tests, ("com.example.test").
2. Create a marker interface in the package as a context qualifier.
3. Provide the marker interface reference as a parameter to basePackageClasses.

Example

IsolatedTest.java

package com.example.test;

@RunWith(SpringJUnit4ClassRunner.class)
@ComponentScan(basePackageClasses = {TestDomain.class})
@SpringApplicationConfiguration(classes = IsolatedTest.Config.class)
public class IsolatedTest {

     String expected = "Read the documentation on @ComponentScan";
     String actual = "Too lazy when I can just search on Stack Overflow.";

      @Test
      public void testSomething() throws Exception {
          assertEquals(expected, actual);
      }

      @ComponentScan(basePackageClasses = {TestDomain.class})
      public static class Config {
      public static void main(String[] args) {
          SpringApplication.run(Config.class, args);
      }
    }
}

...

TestDomain.java

package com.example.test;

public interface TestDomain {
//noop marker
}

@GitaarLAB and @Jukka elaborate that <xmp> tag is obsolete, but still the best. When I use it like this

<xmp>
<div>Lorem ipsum</div>
<p>Hello</p>
</xmp>

then the first EOL is inserted in the code, and it looks awful.

It can be solved by removing that EOL

<xmp><div>Lorem ipsum</div>
<p>Hello</p>
</xmp>

but then it looks bad in the source. I used to solve it with wrapping <div>, but recently I figured out a nice CSS3 rule, I hope it also helps somebody:

xmp { margin: 5px 0; padding: 0 5px 5px 5px; background: #CCC; }
xmp:before { content: ""; display: block; height: 1em; margin: 0 -5px -2em -5px; }

This looks better.

If you want to extract structured data from Wikipedia, you may consider using DbPedia http://dbpedia.org/

It provides means to query data using given criteria using SPARQL and returns data from parsed Wikipedia infobox templates

Here is a quick example how it could be done in .NET http://www.kozlenko.info/blog/2010/07/20/executing-sparql-query-on-wikipedia-in-net/

There are some SPARQL libraries available for multiple platforms to make queries easier

yes you can ... you just need to know the exact package name of the application:

• Facebook - "com.facebook.katana"
• Twitter - "com.twitter.android"
• Instagram - "com.instagram.android"
• Pinterest - "com.pinterest"

And you can create the intent like this

Intent intent = context.getPackageManager().getLaunchIntentForPackage(application);
if (intent != null) {
     // The application exists
     Intent shareIntent = new Intent();
     shareIntent.setAction(Intent.ACTION_SEND);
     shareIntent.setPackage(application);

     shareIntent.putExtra(android.content.Intent.EXTRA_TITLE, title);
     shareIntent.putExtra(Intent.EXTRA_TEXT, description);
     // Start the specific social application
     context.startActivity(shareIntent);
} else {
    // The application does not exist
    // Open GooglePlay or use the default system picker
}

The effect of the 301 would be that the search engines will index /option-a instead of /option-x. Which is probably a good thing since /option-x is not reachable for the search index and thus could have a positive effect on the index. Only if you use this wisely ;-)

After the redirect put exit(); to stop the rest of the script to execute

header("HTTP/1.1 301 Moved Permanently"); 
header("Location: /option-a"); 
exit();

Usually I use the === (triple equals) and __LINE__ , __CLASS__ to locate the error in my code:

$query=mysql_query('SELECT champ FROM table')
or die("SQL Error line  ".__LINE__ ." class ".__CLASS__." : ".mysql_error());

mysql_close();

if(mysql_num_rows($query)===0)
{
    PERFORM ACTION;
}
else
{
    while($r=mysql_fetch_row($query))
    {
          PERFORM ACTION;
    }
}

You can get the week number directly from datetime as string.

>>> import datetime
>>> datetime.date(2010, 6, 16).strftime("%V")
'24'

Also you can get different "types" of the week number of the year changing the strftime parameter for:

%U - Week number of the year (Sunday as the first day of the week) as a zero padded decimal number. All days in a new year preceding the first Sunday are considered to be in week 0. Examples: 00, 01, …, 53

%W - Week number of the year (Monday as the first day of the week) as a decimal number. All days in a new year preceding the first Monday are considered to be in week 0. Examples: 00, 01, …, 53

[...]

(Added in Python 3.6, backported to some distribution's Python 2.7's) Several additional directives not required by the C89 standard are included for convenience. These parameters all correspond to ISO 8601 date values. These may not be available on all platforms when used with the strftime() method.

[...]

%V - ISO 8601 week as a decimal number with Monday as the first day of the week. Week 01 is the week containing Jan 4. Examples: 01, 02, …, 53

from: datetime — Basic date and time types — Python 3.7.3 documentation

I've found out about it from here. It worked for me in Python 2.7.6

std::vector<double>::assign is the way to go, because it's little code. But how does it work, actually? Doesnt't it resize and then copy? In MS implementation of STL I am using it does exactly so.

I'm afraid there's no faster way to implement (re)initializing your std::vector.

This should do it:

$("label[for=comedyclubs]")

If you have non alphanumeric characters in your id then you must surround the attr value with quotes:

$("label[for='comedy-clubs']")

The removeAttr() function only removes HTML attributes. The display is not a HTML attribute, it's a CSS property. You'd like to use css() function instead to manage CSS properties.

But jQuery offers a show() function which does exactly what you want in a concise call:

$("span").show();

Though this might be too late to comment but here's the working code for problems such as yours.

<div id="player">
    <audio autoplay hidden>
     <source src="link/to/file/file.mp3" type="audio/mpeg">
                If you're reading this, audio isn't supported. 
    </audio>
</div>

You can also use this script to figure out more info:

EXEC sp_server_info

The result will be something like that:

attribute_id | attribute_name        | attribute_value

           ?  ?                       ?

using List Comprehension:

>>> L = [1]*5
>>> [x+1 for x in L]
[2, 2, 2, 2, 2]
>>> 

which roughly translates to using a for loop:

>>> newL = []
>>> for x in L:
...     newL+=[x+1]
... 
>>> newL
[2, 2, 2, 2, 2]

or using map:

>>> map(lambda x:x+1, L)
[2, 2, 2, 2, 2]
>>> 

According to Microsoft: syntax for searching is

[ WHERE <search_condition> ]*

And search condition is:

<search_condition> ::= 
    { [ NOT ] <predicate> | ( <search_condition> ) } 
    [ { AND | OR } [ NOT ] { <predicate> | ( <search_condition> ) } ] 
[ ,...n ] 

And predicate is:

<predicate> ::= 
    { expression { = | < > | ! = | > | > = | ! > | < | < = | ! < } expression 

As you can see, you always have to write two expressions to compare. Here search condition is boolean expression like 1=1, a!=b

Do not confuse search expressions with boolean constants like 'True' or 'False'. You can assign boolean constants to BIT variables

DECLARE @B BIT
SET @B='True'

but in TSQL you can not use boolean constants instead of boolean expressions like this:

SELECT * FROM Somewhere WHERE 'True'

It will not work.

But you can use boolean constants to build two-sided search expression like this:

SEARCH * FROM Somewhere WHERE 'True'='True' 

is it possible to extend query results with literals like this?

Yes.

Select Name
From Customers
UNION ALL
Select 'Jason'

• Use UNION to add Jason if it isn't already in the result set.
• Use UNION ALL to add Jason whether or not he's already in the result set.

To avoid getting the encryption error you can also try out below commands

ftp = ftplib.FTP_TLS("ftps.dummy.com")
ftp.login("username", "password")
ftp.prot_p()
file = open("filename", "rb")
ftp.storbinary("STOR filename", file)
file.close()
ftp.close()

ftp.prot_p() ensure that your connections are encrypted

Note that RFC 6266 supersedes the RFCs referenced below. Section 7 outlines some of the related security concerns.

The authority on the content-disposition header is RFC 1806 and RFC 2183. People have also devised content-disposition hacking. It is important to note that the content-disposition header is not part of the HTTP 1.1 standard.

The HTTP 1.1 Standard (RFC 2616) also mentions the possible security side effects of content disposition:

15.5 Content-Disposition Issues

RFC 1806 [35], from which the often implemented Content-Disposition
(see section 19.5.1) header in HTTP is derived, has a number of very
serious security considerations. Content-Disposition is not part of
the HTTP standard, but since it is widely implemented, we are
documenting its use and risks for implementors. See RFC 2183 [49]
(which updates RFC 1806) for details.

For version 4.0, 4.5 on Windows

Changing a variable doesn't magically execute code within the if-block. Place the common code in a function, then bind the event, and call the function:

$(document).ready(function() {
    // Optimalisation: Store the references outside the event handler:
    var $window = $(window);
    var $pane = $('#pane1');

    function checkWidth() {
        var windowsize = $window.width();
        if (windowsize > 440) {
            //if the window is greater than 440px wide then turn on jScrollPane..
            $pane.jScrollPane({
               scrollbarWidth:15, 
               scrollbarMargin:52
            });
        }
    }
    // Execute on load
    checkWidth();
    // Bind event listener
    $(window).resize(checkWidth);
});

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

You can define attribute as BINARY or use INSTR or STRCMP to perform your search.

Sorry for digging out an old thread, but I think sunetos' answer isn't correct (or isn't the full answer). I've done some experiments (using ProcessStartInfo in c#) and it seems that the 'arguments' string for a commandline command is limited to 2048 characters in XP and 32768 characters in Win7. I'm not sure what the 8191 limit refers to, but I haven't found any evidence of it yet.

You escape ' by doubling it, so:

Select * from tblStudents where name like 'Daniel O''Neal' 

Note that if you're accepting "Daniel O'Neal" from user input, the broken quotation is a serious security issue. You should always sanitize the string or use parametrized queries.

If the IGNORE statement won't work like in my case, you can use the below statement:

CREATE TABLE your_table_deduped LIKE your_table;


INSERT your_table_deduped
SELECT *
FROM your_table
GROUP BY index1_id,
         index2_id;

RENAME TABLE your_table TO your_table_with_dupes;

RENAME TABLE your_table_deduped TO your_table;

#OPTIONAL
ALTER TABLE `your_table` ADD UNIQUE `unique_index` (`index1_id`, `index2_id`);

#OPTIONAL
DROP TABLE your_table_with_dupes;

fgets.

To read from the stdin:

char string[512];

fgets(string, sizeof(string), stdin); /* no buffer overflows here, you're safe! */

If you install Web Essentials into Visual studio you can go to Edit => Past special => paste JSON as class.

That is probably the easiest there is.

If you start R from a desktop icon, you can add the --internet flag to the target line (right click -> Properties) e.g.

"C:\Program Files\R\R-2.8.1\bin\Rgui.exe" --internet2 

if you have

<span class="label label-default">New</span>

just add the style="font-size:XXpx;", ej.

<span class="label label-default" style="font-size:15px;">New</span>

The standard exceptions can be constructed from a std::string:

#include <stdexcept>

char const * configfile = "hardcode.cfg";
std::string const anotherfile = get_file();

throw std::runtime_error(std::string("Failed: ") + configfile);
throw std::runtime_error("Error: " + anotherfile);

Note that the base class std::exception can not be constructed thus; you have to use one of the concrete, derived classes.

Code for java.util.Calendar

If you have to use java.util.Calendar, I suspect you want:

int days = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);

Code for Joda Time

Personally, however, I'd suggest using Joda Time instead of java.util.{Calendar, Date} to start with, in which case you could use:

int days = chronology.dayOfMonth().getMaximumValue(date);

Note that rather than parsing the string values individually, it would be better to get whichever date/time API you're using to parse it. In java.util.* you might use SimpleDateFormat; in Joda Time you'd use a DateTimeFormatter.

I came across this for css

span, p{overflow:hidden; white-space: nowrap;}

via similar stackoverflow question

I think you can use prtdiag or prtconf on many UNIXs

the main problem occur when you don't have date --date option available and you don't have permission to install it, then try below -

Previous month
#cal -3|awk 'NR==1{print toupper(substr($1,1,3))"-"$2}'
DEC-2016 
Current month
#cal -3|awk 'NR==1{print toupper(substr($3,1,3))"-"$4}'
JAN-2017
Next month
#cal -3|awk 'NR==1{print toupper(substr($5,1,3))"-"$6}'
FEB-2017

The for-in statement iterates over the enumerable properties of an object, in arbitrary order.

The loop will iterate over all enumerable properties of the object itself and those the object inherits from its constructor's prototype

You can think of it as "for in" basically iterates and list out all the keys.

var str = 'abc';
var arrForOf = [];
var arrForIn = [];

for(value of str){
  arrForOf.push(value);
}

for(value in str){
  arrForIn.push(value);
}

console.log(arrForOf); 
// ["a", "b", "c"]
console.log(arrForIn); 
// ["0", "1", "2", "formatUnicorn", "truncate", "splitOnLast", "contains"]

In our case on IIS 8 we found the error was produced when attempting to view Authentication" for a site, when:

1. The server Feature Delegation marked as "Authentication - Windows" = "Read Only"
2. The site had a web.config that explicitly referenced windows authentication; e.g.,

Marking the site Feature Delegation "Authentication - Windows" = "Read/Write", the error went away. It appears that, with the feature marked "Read Only", the web.config is not allowed to reference it at all even to disable it, as this apparently constitutes a write.

Some values are serialized differently between simplejson and json.

Notably, instances of collections.namedtuple are serialized as arrays by json but as objects by simplejson. You can override this behaviour by passing namedtuple_as_object=False to simplejson.dump, but by default the behaviours do not match.

>>> import collections, simplejson, json
>>> TupleClass = collections.namedtuple("TupleClass", ("a", "b"))
>>> value = TupleClass(1, 2)
>>> json.dumps(value)
'[1, 2]'
>>> simplejson.dumps(value)
'{"a": 1, "b": 2}'
>>> simplejson.dumps(value, namedtuple_as_object=False)
'[1, 2]'

Easier with inline coding

<button type="button" ng-click="showmore = (showmore !=null && showmore) ? false : true;" class="btn float-right" data-toggle="collapse" data-target="#moreoptions">
            <span class="glyphicon" ng-class="showmore ? 'glyphicon-collapse-up': 'glyphicon-collapse-down'"></span>
            {{ showmore !=null && showmore ? "Hide More Options" : "Show More Options" }}
        </button>


<div id="moreoptions" class="collapse">Your Panel</div>

That should help

df.groupby(['NFF', 'ABUSE']).size().unstack().plot(kind='bar', stacked=True)

IMO, it's a clean way to achieve super.super.sayYourName() behavior in Java.

public class GrandMa {  
    public void sayYourName(){  
        System.out.println("Grandma Fedora");  
    }  
}  

public class Mama extends GrandMa {  
    public void sayYourName(boolean lie){  
        if(lie){   
            super.sayYourName();  
        }else {  
            System.out.println("Mama Stephanida");  
        }  
    }  
}  

public class Daughter extends Mama {  
    public void sayYourName(boolean lie){  
        if(lie){   
            super.sayYourName(lie);  
        }else {  
            System.out.println("Little girl Masha");  
        }  
    }  
}  

public class TestDaughter {
    public static void main(String[] args){
        Daughter d = new Daughter();

        System.out.print("Request to lie: d.sayYourName(true) returns ");
        d.sayYourName(true);
        System.out.print("Request not to lie: d.sayYourName(false) returns ");
        d.sayYourName(false);
    }
}

Output:

Request to lie: d.sayYourName(true) returns Grandma Fedora
Request not to lie: d.sayYourName(false) returns Little girl Masha

I was having your problem, and this is how I fixed it. The following steps are a working way to add a library. I had done the first two steps right, but I hadn't done the last one by dragging the ".jar" file direct from the file system into the "lib" folder on my eclipse project. Additionally, I had to remove the previous version of the library from both the build path and the "lib" folder.

Step 1 - Add .jar to build path

Step 2 - Associate sources and javadocs (optional)

Step 3 - Actually drag .jar file into "lib" folder (not optional)

You first have to tell Gnuplot to use a style that uses points, e.g. with points or with linespoints. Try for example:

plot sin(x) with points

Output:

Now try:

plot sin(x) with points pointtype 5

Output:

You may also want to look at the output from the test command which shows you the capabilities of the current terminal. Here are the capabilities for my pngairo terminal:

You have to modify two possible limits:

In conf\server.xml

<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
                maxPostSize="67589953" />

In webapps\manager\WEB-INF\web.xml

<multipart-config>
  <!-- 52MB max -->
  <max-file-size>52428800</max-file-size>
  <max-request-size>52428800</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

I just placed a short-cut to the XAMPP control panel in my startup folder. That works just fine on Window 7. Start -> All Programs -> Startup. There is also an option to start XAMPP control panel minimized, that is very useful for getting a clean unobstructed view of your desktop at start-up.**

• If you are using Android Studio, you can find the option in the Flutter Inspector tab --> More Actions.

Receive POST and GET request in nodejs :

1).Server

    var http = require('http');
    var server = http.createServer ( function(request,response){

    response.writeHead(200,{"Content-Type":"text\plain"});
    if(request.method == "GET")
        {
            response.end("received GET request.")
        }
    else if(request.method == "POST")
        {
            response.end("received POST request.");
        }
    else
        {
            response.end("Undefined request .");
        }
});

server.listen(8000);
console.log("Server running on port 8000");

2). Client :

var http = require('http');

var option = {
    hostname : "localhost" ,
    port : 8000 ,
    method : "POST",
    path : "/"
} 

    var request = http.request(option , function(resp){
       resp.on("data",function(chunck){
           console.log(chunck.toString());
       }) 
    })
    request.end();

Performing a single click on an HTML element: Simply do element.click(). Most major browsers support this.

To repeat the click more than once: Add an ID to the element to uniquely select it:

<a href="#" target="_blank" id="my-link" onclick="javascript:Test('Test');">Google Chrome</a>

and call the .click() method in your JavaScript code via a for loop:

var link = document.getElementById('my-link');
for(var i = 0; i < 50; i++)
   link.click();

The common convention would be to put it in a .sh file that looks like this -

#!/bin/bash
java -cp  ".;./supportlibraries/Framework_Core.jar;... etc

Note that '\' become '/'.

You could execute as

sh myfile.sh

or set the x bit on the file

chmod +x myfile.sh

and then just call

myfile.sh

Firstly, you probably want to add a return false; to the bottom of your Submit() method in JavaScript (so it stops the submit, since you're handling it in AJAX).

You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:

$.ajax({
        type: "POST",
        url: "Default.aspx/OnSubmit",
        data: dataValue,                
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
        },
        success: function (result) {
            alert("We returned: " + result);
        }
    });

I found the following to work on Chrome, Firefox and IE11:

$('iframe').load(function () {
    $('iframe').height($('iframe').contents().height());
});

When the Iframes content is done loading the event will fire and it will set the IFrames height to that of its content. This will only work for pages within the same domain as that of the IFrame.

I think in this case concat is what you want:

In [12]:

pd.concat([df,df1], axis=0, ignore_index=True)
Out[12]:
   attr_1  attr_2  attr_3  id  quantity
0       0       1     NaN   1        20
1       1       1     NaN   2        23
2       1       1     NaN   3        19
3       0       0     NaN   4        19
4       1     NaN       0   5         8
5       0     NaN       1   6        13
6       1     NaN       1   7        20
7       1     NaN       1   8        25

by passing axis=0 here you are stacking the df's on top of each other which I believe is what you want then producing NaN value where they are absent from their respective dfs.

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

You can get access to the history object's properties and the closest 's match via the withRouter higher-order component. withRouter will pass updated match, location, and history props to the wrapped component whenever it renders.

import React, { Component } from 'react'
import { withRouter } from 'react-router'; 
// you can also import "withRouter" from 'react-router-dom';

class Example extends Component {
    render() {
        const { match, location, history } = this.props
        return (
            <div>
                <div>You are now at {location.pathname}</div>
                <button onClick={() => history.push('/')}>{'Home'}</button>
            </div>
        )
    }
}


export default withRouter(Example)

According to The W3C:

This attribute sets the size of the font. Possible values:

• An integer between 1 and 7. This sets the font to some fixed size, whose rendering depends on the user agent. Not all user agents may render all seven sizes.
• A relative increase in font size. The value "+1" means one size larger. The value "-3" means three sizes smaller. All sizes belong to the scale of 1 to 7.

Hence, the conversion you're asking for is not possible. The browser is not required to use specific sizes with specific size attributes.

Also note that use of the font element is discouraged by W3 in favor of style sheets.

You can use the crosstab() function of the additional module tablefunc - which you have to install once per database. Since PostgreSQL 9.1 you can use CREATE EXTENSION for that:

CREATE EXTENSION tablefunc;

In your case, I believe it would look something like this:

CREATE TABLE t (Section CHAR(1), Status VARCHAR(10), Count integer);

INSERT INTO t VALUES ('A', 'Active',   1);
INSERT INTO t VALUES ('A', 'Inactive', 2);
INSERT INTO t VALUES ('B', 'Active',   4);
INSERT INTO t VALUES ('B', 'Inactive', 5);

SELECT row_name AS Section,
       category_1::integer AS Active,
       category_2::integer AS Inactive
FROM crosstab('select section::text, status, count::text from t',2)
            AS ct (row_name text, category_1 text, category_2 text);

Use extension for UIImageView to Load URL Images.

let imageCache = NSCache<NSString, UIImage>()

extension UIImageView {

    func imageURLLoad(url: URL) {

        DispatchQueue.global().async { [weak self] in
            func setImage(image:UIImage?) {
                DispatchQueue.main.async {
                    self?.image = image
                }
            }
            let urlToString = url.absoluteString as NSString
            if let cachedImage = imageCache.object(forKey: urlToString) {
                setImage(image: cachedImage)
            } else if let data = try? Data(contentsOf: url), let image = UIImage(data: data) {
                DispatchQueue.main.async {
                    imageCache.setObject(image, forKey: urlToString)
                    setImage(image: image)
                }
            }else {
                setImage(image: nil)
            }
        }
    }
}

Use -Xms and -Xmx command line options when runing java:

-Xms<size>        set initial Java heap size
-Xmx<size>        set maximum Java heap size

For more help type java -X in command line.

You don't have to use Calendar. You can just play with timestamps :

Date d = initDate();//intialize your date to any date 
Date dateBefore = new Date(d.getTime() - n * 24 * 3600 * 1000 l ); //Subtract n days   

UPDATE DO NOT FORGET TO ADD "l" for long by the end of 1000.

Please consider the below WARNING:

Adding 1000*60*60*24 milliseconds to a java date will once in a great while add zero days or two days to the original date in the circumstances of leap seconds, daylight savings time and the like. If you need to be 100% certain only one day is added, this solution is not the one to use.

I used below method, which doesn't require any change in config, tested on mysql-5.5.51-winx64 and 5.5.50-MariaDB:

put 'load data...' in .sql file (ex: LoadTableName.sql)

LOAD DATA INFILE 'D:\\Work\\TableRecords.csv' INTO TABLE tbl1 FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES (col1,col2);

then:

mysql -uroot -pStr0ngP@ss -Ddatabasename -e "source D:\Work\LoadTableName.sql"

The simplest and shortest way is to use CmdTool library.

new Cmd()
         .configuring(new WorkDir("C:/Program Files/Flowella"))
         .command("cmd.exe", "/c", "start")
         .execute();

You can find more examples here.

The first part of your question is easy. As already pointed out, cut accepts omission of either the starting or the ending index of a column range, interpreting this as meaning either “from the start to column n (inclusive)” or “from column n (inclusive) to the end,” respectively:

$ printf 'this:is:a:test' | cut -d: -f-2
this:is
$ printf 'this:is:a:test' | cut -d: -f3-
a:test

It also supports combining ranges. If you want, e.g., the first 3 and the last 2 columns in a row of 7 columns:

$ printf 'foo:bar:baz:qux:quz:quux:quuz' | cut -d: -f-3,6-
foo:bar:baz:quux:quuz

However, the second part of your question can be a bit trickier depending on what kind of input you’re expecting. If by “last n columns” you mean “last n columns (regardless of their indices in the overall row)” (i.e. because you don’t necessarily know how many columns you’re going to find in advance) then sadly this is not possible to accomplish using cut alone. In order to effectively use cut to pull out “the last n columns” in each line, the total number of columns present in each line must be known beforehand, and each line must be consistent in the number of columns it contains.

If you do not know how many “columns” may be present in each line (e.g. because you’re working with input that is not strictly tabular), then you’ll have to use something like awk instead. E.g., to use awk to pull out the last 2 “columns” (awk calls them fields, the number of which can vary per line) from each line of input:

$ printf '/a\n/a/b\n/a/b/c\n/a/b/c/d\n' | awk -F/ '{print $(NF-1) FS $(NF)}'
/a
a/b
b/c
c/d

GNU mailutils's 'mail' command doesn't let you do this (easily at least). But If you install 'heirloom-mailx', its mail command (mailx) has the '-r' option to override the default '$USER@$HOSTNAME' from field.

echo "Hello there" | mail -s "testing" -r [email protected] [email protected]

Works for 'mailx' but not 'mail'.

$ ls -l /usr/bin/mail
lrwxrwxrwx 1 root root 22 2010-12-23 08:33 /usr/bin/mail -> /etc/alternatives/mail
$ ls -l /etc/alternatives/mail
lrwxrwxrwx 1 root root 23 2010-12-23 08:33 /etc/alternatives/mail -> /usr/bin/heirloom-mailx

If in the lower right corner it says "2 processes running..." or similar, you may just need to wait for that to finish, since it may take time to download all the jars.

Drag the variable from Variables pane to Watch pane and voila!

Try :

class round{
public static void main(String args[]){

double a = 123.13698;
double roundOff = Math.round(a*100)/100;
String.format("%.3f", roundOff); //%.3f defines decimal precision you want
System.out.println(roundOff);   }}

In CSS 2.1, the effect of 'min-height' and 'max-height' on tables, inline tables, table cells, table rows, and row groups is undefined.

So try wrapping the content in a div, and give the div a min-height jsFiddle here

<table cellspacing="0" cellpadding="0" border="0" style="width:300px">
    <tbody>
        <tr>
            <td>
                <div style="min-height: 100px; background-color: #ccc">
                    Hello World !
                </div>
            </td>
            <td>
                <div style="min-height: 100px; background-color: #f00">
                    Good Morning !
                </div>
            </td>
        </tr>

You can make use of the SchUseStrongCrypto registry setting to require all .NET applications to use TLS 1.2 instead of 1.0 by default.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

If you want to get an object, using get() is more straightforward:

obj = Class.objects.get(pk=this_object_id)

Try disabling iptables: service iptables stop

If this works, enable TCP port 80 to your firewall rules: run system-config-selinux from root, and enable TCP port 80 (HTTP) on your firewall.

I had that issue : use path module

const path = require('path');

and also do not forget to create the uploads directory first period.

You can also use Requestify, a really cool and very simple HTTP client I wrote for nodeJS + it supports caching.

Just do the following for executing a POST request:

var requestify = require('requestify');

requestify.post('http://example.com', {
    hello: 'world'
})
.then(function(response) {
    // Get the response body (JSON parsed or jQuery object for XMLs)
    response.getBody();
});

Yes, window.onfocus and window.onblur should work for your scenario:

}

There is a new open-source effort to develop a Java library for push notifications on Android based on the Meteor web server. You can check it out at the Deacon Project Blog, where you'll find links to Meteor and the project's GitHub repository. We need developers, so please spread the word!

One option is to use altertify, this gives a nice looking alert box.

Simply include the required libraries from here, and use the following piece of code to display the alert box.

alertify.confirm("This is a confirm dialog.",
  function(){
    alertify.success('Ok');
  },
  function(){
    alertify.error('Cancel');
  });

The output will look like this. To see it in action here is the demo

Perhaps use plt.annotate:

Through the original question is not exactly about the locale itself all other locale related questions are referencing to this one. That's why I wanted to clarify the issue here. I used this question as a starting point for my own locale switching code and found out that the method is not exactly correct. It works, but only until any configuration change (e.g. screen rotation) and only in that particular Activity. Playing with a code for a while I have ended up with the following approach:

I have extended android.app.Application and added the following code:

public class MyApplication extends Application
{
    private Locale locale = null;

    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        if (locale != null)
        {
            newConfig.locale = locale;
            Locale.setDefault(locale);
            getBaseContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());
        }
    }

    @Override
    public void onCreate()
    {
        super.onCreate();

        SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);

        Configuration config = getBaseContext().getResources().getConfiguration();

        String lang = settings.getString(getString(R.string.pref_locale), "");
        if (! "".equals(lang) && ! config.locale.getLanguage().equals(lang))
        {
            locale = new Locale(lang);
            Locale.setDefault(locale);
            config.locale = locale;
            getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
        }
    }
}

This code ensures that every Activity will have custom locale set and it will not be reset on rotation and other events.

I have also spent a lot of time trying to make the preference change to be applied immediately but didn't succeed: the language changed correctly on Activity restart, but number formats and other locale properties were not applied until full application restart.

Changes to AndroidManifest.xml

Don't forget to add android:configChanges="layoutDirection|locale" to every activity at AndroidManifest, as well as the android:name=".MyApplication" to the <application> element.

Escape the quotes with backslashes:

printf("She said \"time flies like an arrow, but fruit flies like a banana\"."); 

There are special escape characters that you can use in string literals, and these are denoted with a leading backslash.

Invoke the sqlite3 utility on the database file, and use its special dot commands:

• .tables will list tables
• .schema [tablename] will show the CREATE statement(s) for a table or tables

There are many other useful builtin dot commands -- see the documentation at http://www.sqlite.org/sqlite.html, section Special commands to sqlite3.

Example:

sqlite> entropy:~/Library/Mail>sqlite3 Envelope\ Index
SQLite version 3.6.12
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .tables
addresses              ews_folders            subjects
alarms                 feeds                  threads
associations           mailboxes              todo_notes
attachments            messages               todos
calendars              properties             todos_deleted_log
events                 recipients             todos_server_snapshot
sqlite> .schema alarms
CREATE TABLE alarms (ROWID INTEGER PRIMARY KEY AUTOINCREMENT, alarm_id,
                     todo INTEGER, flags INTEGER, offset_days INTEGER,
                     reminder_date INTEGER, time INTEGER, argument,
                     unrecognized_data BLOB);
CREATE INDEX alarm_id_index ON alarms(alarm_id);
CREATE INDEX alarm_todo_index ON alarms(todo);

Note also that SQLite saves the schema and all information about tables in the database itself, in a magic table named sqlite_master, and it's also possible to execute normal SQL queries against that table. For example, the documentation link above shows how to derive the behavior of the .schema and .tables commands, using normal SQL commands (see section: Querying the database schema).

You can analyse problem (dex file references) using Android Studio:

Build -> Analyse APK ..

On the result panel click on classes.dex file

And you'll see:

My site faces same issue too.

Using Facebook debug tool is no help at all. Fetch new data but not IMAGE CACHE.

I forced facebook to clear IMAGE CACHE by add www. into image url. In your case is remove www. and config web server redirect.

 add/remove www. in image url should solve the problem

Maybe the method document.createElement(); is what you're looking for.

ReLU(x) also is equal to (x+abs(x))/2

Both the field name and the value should be url encoded. format of the post data and query string are the same

The .net way of doing is something like this

NameValueCollection outgoingQueryString = HttpUtility.ParseQueryString(String.Empty);
outgoingQueryString.Add("field1","value1");
outgoingQueryString.Add("field2", "value2");
string postdata = outgoingQueryString.ToString();

This will take care of encoding the fields and the value names

var s = '<div id="myDiv"></div>';
var htmlObject = document.createElement('div');
htmlObject.innerHTML = s;
htmlObject.getElementById("myDiv").style.marginTop = something;

So does C99.

The IEEE 754 floating point representation used by all modern processors has several special bit patterns reserved for positive infinity (sign=0, exp=~0, frac=0), negative infinity (sign=1, exp=~0, frac=0), and many NaN (Not a Number: exp=~0, frac?0).

All you need to worry about: some arithmetic may cause floating point exceptions/traps, but those aren't limited to only these "interesting" constants.

The issue here that the Python version used to build your Lambda function dependencies (on your own machine) is different than the selected Python version for your Lambda function. This case is common especially if the Numpy library part of your dependencies.

Example: Your machine's python version: 3.6 ---> Lambda python version 3.6

Just overwriting of getInputStream() did not work in my case. My server implementation seems to parse parameters without calling this method. I did not find any other way, but re-implement the all four getParameter* methods as well. Here is the code of getParameterMap (Apache Http Client and Google Guava library used):

@Override
public Map<String, String[]> getParameterMap() {
    Iterable<NameValuePair> params = URLEncodedUtils.parse(getQueryString(), NullUtils.UTF8);

    try {
        String cts = getContentType();
        if (cts != null) {
            ContentType ct = ContentType.parse(cts);
            if (ct.getMimeType().equals(ContentType.APPLICATION_FORM_URLENCODED.getMimeType())) {
                List<NameValuePair> postParams = URLEncodedUtils.parse(IOUtils.toString(getReader()), NullUtils.UTF8);
                params = Iterables.concat(params, postParams);
            }
        }
    } catch (IOException e) {
        throw new IllegalStateException(e);
    }
    Map<String, String[]> result = toMap(params);
    return result;
}

public static Map<String, String[]> toMap(Iterable<NameValuePair> body) {
    Map<String, String[]> result = new LinkedHashMap<>();
    for (NameValuePair e : body) {
        String key = e.getName();
        String value = e.getValue();
        if (result.containsKey(key)) {
            String[] newValue = ObjectArrays.concat(result.get(key), value);
            result.remove(key);
            result.put(key, newValue);
        } else {
            result.put(key, new String[] {value});
        }
    }
    return result;
}

I've just had the same problem on a CentOS 7 box.

Seems I'd hit selinux. Putting selinux into permissive mode (setenforce permissive) has worked round the problem for now. I'll try and get back with a proper fix.

For MongoDB earlier than 2.6, the command to add a root user is addUser (e.g.)

db.addUser({user:'admin',pwd:'<password>',roles:["root"]})

To find any file location

1. In windows start menu Search box
2. type in svcutil.exe
3. Wait for results to populate
4. Right click on svcutil.exe and Select 'Open file location'
5. Copy Windows explorer path

Also, for the above answers, in iOS 13 and later there is a clean way

let image = UIImage(named: "imageName")?.withTintColor(.white, renderingMode: .alwaysTemplate)

javax.servlet is a package that's part of Java EE (Java Enterprise Edition). You've got the JDK for Java SE (Java Standard Edition).

You could use the Java EE SDK for example.

Alternatively simple servlet containers such as Apache Tomcat also come with this API (look for servlet-api.jar).

here email is your email-id.

  public boolean validateEmail(String email) {

    Pattern pattern;
    Matcher matcher;
    String EMAIL_PATTERN = "^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
    pattern = Pattern.compile(EMAIL_PATTERN);
    matcher = pattern.matcher(email);
    return matcher.matches();

According to w3schools: http://www.w3schools.com/cssref/css3_pr_transform.asp

The transform property is supported in Internet Explorer 10, Firefox, and Opera. Internet Explorer 9 supports an alternative, the -ms-transform property (2D transforms only). Safari and Chrome support an alternative, the -webkit-transform property (3D and 2D transforms). Opera supports 2D transforms only.

This is a 2D transform, so it should work, with the vendor prefixes, on Chrome, Firefox, Opera, Safari, and IE9+.

Other answers used :before to stop it from flipping the inner content. I used this on my footer (to vertically-mirror the image from my header):

HTML:

<footer>
<p><a href="page">Footer Link</a></p>
<p>&copy; 2014 Company</p>
</footer>

CSS:

footer {
background:url(/img/headerbg.png) repeat-x 0 0;

/* flip background vertically */
-webkit-transform:scaleY(-1);
-moz-transform:scaleY(-1);
-ms-transform:scaleY(-1);
-o-transform:scaleY(-1);
transform:scaleY(-1);
}

/* undo the vertical flip for all child elements */
footer * {
-webkit-transform:scaleY(-1);
-moz-transform:scaleY(-1);
-ms-transform:scaleY(-1);
-o-transform:scaleY(-1);
transform:scaleY(-1);
}

So you end up flipping the element and then re-flipping all its children. Works with nested elements, too.

In a SQL Server trigger you have available two psdeuotables called inserted and deleted. These contain the old and new values of the record.

So within the trigger (you can look up the create trigger parts easily) you would do something like this:

Insert table2 (user_id, user_name)
select user_id, user_name from inserted i
left join table2 t on i.user_id = t.userid
where t.user_id is null

When writing triggers remember they act once on the whole batch of information, they do not process row-by-row. So account for multiple row inserts in your code.

Use the remove/erase idiom:

std::vector<int>& vec = myNumbers; // use shorter name
vec.erase(std::remove(vec.begin(), vec.end(), number_in), vec.end());

What happens is that remove compacts the elements that differ from the value to be removed (number_in) in the beginning of the vector and returns the iterator to the first element after that range. Then erase removes these elements (whose value is unspecified).

Log in as root, then run the following MySQL commands:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
FLUSH PRIVILEGES;

Pass float to sleep, like sleep 0.1

I know this is and old question, but i was faced with the same problem recently and none of the answers worked for me:

• Couldn't find an old Foxit Reader version
• As @pilkch said 2Printer adds a report page
• Adobe Reader opens a gui

After searching a little more i found this: http://www.columbia.edu/~em36/pdftoprinter.html.

It's a simple exe that you call with the filename and it prints to the default printer (or one that you specify). From the site:

PDFtoPrinter is a program for printing PDF files from the Windows command line. The program is designed generally for the Windows command line and also for use with the vDos DOS emulator.

To print a PDF file to the default Windows printer, use this command:

PDFtoPrinter.exe filename.pdf

To print to a specific printer, add the name of the printer in quotation marks:

PDFtoPrinter.exe filename.pdf "Name of Printer"

If you want to print to a network printer, use the name that appears in Windows print dialogs, like this (and be careful to note the two backslashes at the start of the name and the single backslash after the servername):

PDFtoPrinter.exe filename.pdf "\\SERVER\PrinterName"

As RichieHindle pointed out the shortcut for column (block) selection is Alt+Shift+A. The problem I ran into is that the Android SDK on Eclipse uses 3 shortcuts that all start with Alt+Shift+A, so if you type that, you'll be given a choice of continuing with D, S, or R.

To solve this I redefined the column selection as Alt+Shift+A,A (Alt, Shift, A pressed together and then followed by a subsequent A). To do this go to Windows > Preferences then type keys or navigate to General > Keys. Under the Keys enter the filter text of block selection to quickly find the shortcut listing for toggle block selection. Here you can adjust the shortcut for column selection as you wish.

With version v2018.2.1

Go to

Preference > Editor > Inspections > Java > Serialization issues > toggle "Serializable class without 'serialVersionUID'".

A warning should appear next to the class declaration.

I don't know exactly what you mean by efficiency but this is straightforward and it works for me:

SELECT
    DB_NAME(db.database_id) DatabaseName,
    (CAST(mfrows.RowSize AS FLOAT)*8)/1024 RowSizeMB,
    (CAST(mflog.LogSize AS FLOAT)*8)/1024 LogSizeMB,
    (CAST(mfstream.StreamSize AS FLOAT)*8)/1024 StreamSizeMB,
    (CAST(mftext.TextIndexSize AS FLOAT)*8)/1024 TextIndexSizeMB
FROM sys.databases db
    LEFT JOIN (SELECT database_id, SUM(size) RowSize FROM sys.master_files WHERE type = 0 GROUP BY database_id, type) mfrows ON mfrows.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) LogSize FROM sys.master_files WHERE type = 1 GROUP BY database_id, type) mflog ON mflog.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) StreamSize FROM sys.master_files WHERE type = 2 GROUP BY database_id, type) mfstream ON mfstream.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) TextIndexSize FROM sys.master_files WHERE type = 4 GROUP BY database_id, type) mftext ON mftext.database_id = db.database_id

With results like:

DatabaseName  RowSizeMB LogSizeMB StreamSizeMB TextIndexSizeMB
------------- --------- --------- ------------ ---------------
master        4         1.25      NULL         NULL
model         2.25      0.75      NULL         NULL
msdb          14.75     8.1875    NULL         NULL
tempdb        8         0.5       NULL         NULL

Note: was inspired by this article

I agree with the existing answers that the second form is better because it does not have any side effects and is easier to parallelise (just use a parallel stream).

Performance wise, it appears they are equivalent until you start using parallel streams. In that case, map will perform really much better. See below the micro benchmark results:

Benchmark                         Mode  Samples    Score   Error  Units
SO28319064.forEach                avgt      100  187.310 ± 1.768  ms/op
SO28319064.map                    avgt      100  189.180 ± 1.692  ms/op
SO28319064.mapWithParallelStream  avgt      100   55,577 ± 0,782  ms/op

You can't boost the first example in the same manner because forEach is a terminal method - it returns void - so you are forced to use a stateful lambda. But that is really a bad idea if you are using parallel streams.

Finally note that your second snippet can be written in a sligthly more concise way with method references and static imports:

myFinalList = myListToParse.stream()
    .filter(Objects::nonNull)
    .map(this::doSomething)
    .collect(toList()); 

Your Customer class has to be discovered by CDI as a bean. For that you have two options:

1. Put a bean defining annotation on it. As @Model is a stereotype it's why it does the trick. A qualifier like @Named is not a bean defining annotation, reason why it doesn't work

2. Change the bean discovery mode in your bean archive from the default "annotated" to "all" by adding a beans.xml file in your jar.

Keep in mind that @Named has only one usage : expose your bean to the UI. Other usages are for bad practice or compatibility with legacy framework.

Seems like only real solutions today revolve around scaling out or sharding. All modern databases (NoSQLs as well as NewSQLs) support horizontal scaling right out of the box, at the database layer, without the need for the application to have sharding code or something.

Unfortunately enough, for the trusted good-old MySQL, sharding is not provided "out of the box". ScaleBase (disclaimer: I work there) is a maker of a complete scale-out solution an "automatic sharding machine" if you like. ScaleBae analyzes your data and SQL stream, splits the data across DB nodes, and aggregates in runtime – so you won’t have to! And it's free download.

Don't get me wrong, NoSQLs are great, they're new, new is more choice and choice is always good!! But choosing NoSQL comes with a price, make sure you can pay it...

You can see here some more data about MySQL, NoSQL...: http://www.scalebase.com/extreme-scalability-with-mongodb-and-mysql-part-1-auto-sharding

Hope that helped.

Have a look at the Requests exception docs. In short:

In the event of a network problem (e.g. DNS failure, refused connection, etc), Requests will raise a ConnectionError exception.

In the event of the rare invalid HTTP response, Requests will raise an HTTPError exception.

If a request times out, a Timeout exception is raised.

If a request exceeds the configured number of maximum redirections, a TooManyRedirects exception is raised.

All exceptions that Requests explicitly raises inherit from requests.exceptions.RequestException.

To answer your question, what you show will not cover all of your bases. You'll only catch connection-related errors, not ones that time out.

What to do when you catch the exception is really up to the design of your script/program. Is it acceptable to exit? Can you go on and try again? If the error is catastrophic and you can't go on, then yes, you may abort your program by raising SystemExit (a nice way to both print an error and call sys.exit).

You can either catch the base-class exception, which will handle all cases:

try:
    r = requests.get(url, params={'s': thing})
except requests.exceptions.RequestException as e:  # This is the correct syntax
    raise SystemExit(e)

Or you can catch them separately and do different things.

try:
    r = requests.get(url, params={'s': thing})
except requests.exceptions.Timeout:
    # Maybe set up for a retry, or continue in a retry loop
except requests.exceptions.TooManyRedirects:
    # Tell the user their URL was bad and try a different one
except requests.exceptions.RequestException as e:
    # catastrophic error. bail.
    raise SystemExit(e)

As Christian pointed out:

If you want http errors (e.g. 401 Unauthorized) to raise exceptions, you can call Response.raise_for_status. That will raise an HTTPError, if the response was an http error.

An example:

try:
    r = requests.get('http://www.google.com/nothere')
    r.raise_for_status()
except requests.exceptions.HTTPError as err:
    raise SystemExit(err)

Will print:

404 Client Error: Not Found for url: http://www.google.com/nothere

To get the date to show as the current time zone I used the following.

if let timeResult = (jsonResult["dt"] as? Double) {
     let date = NSDate(timeIntervalSince1970: timeResult)
     let dateFormatter = NSDateFormatter()
     dateFormatter.timeStyle = NSDateFormatterStyle.MediumStyle //Set time style
     dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle //Set date style
     dateFormatter.timeZone = NSTimeZone()
     let localDate = dateFormatter.stringFromDate(date)
}

Swift 3.0 Version

if let timeResult = (jsonResult["dt"] as? Double) {
    let date = Date(timeIntervalSince1970: timeResult)
    let dateFormatter = DateFormatter()
    dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
    dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
    dateFormatter.timeZone = self.timeZone
    let localDate = dateFormatter.string(from: date)                     
}

Swift 5

if let timeResult = (jsonResult["dt"] as? Double) {
    let date = Date(timeIntervalSince1970: timeResult)
    let dateFormatter = DateFormatter()
    dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
    dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
    dateFormatter.timeZone = .current
    let localDate = dateFormatter.string(from: date)                                
}

no your ans is Wrong

Selection of Al and Ah is from AX not from EAX

e.g

EAX=0000 0000 0000 0000 0000 0000 0000 0111

So if we call AX it should return

0000 0000 0000 0111

if we call AH it should return

0000 0000

and when we call AL it should return

0000 0111

Example number 2

EAX: 22 33 55 77
AX: 55 77
AH: 55    
AL: 77

example 3

EAX: 1111 0000 0000 0000 0000 0000 0000 0111    
AX= 0000 0000 0000 0111
AH= 0000 0000
AL= 0000 0111  

In our case it was an empty AndroidManifest.xml.

While upgrading Eclispe we ran into the usual trouble, and AndroidManifest.xml must have been checked into SVN by the build script after being clobbered.

Found it by compiling from inside Eclipse, instead of from the command line.

200 (cache) means Firefox is simply using the locally cached version. This is the fastest because no request to the Web server is made.

304 means Firefox is sending a "If-Modified-Since" conditional request to the Web server. If the file has not been updated since the date sent by the browser, the Web server returns a 304 response which essentially tells Firefox to use its cached version. It is not as fast as 200 (cache) because the request is still sent to the Web server, but the server doesn't have to send the contents of the file.

To your last question, I don't know why the two JavaScript files in the same directory are returning different results.

Script its left and top properties as the number of pixels from the left edge and top edge respectively. It must have position: absolute;

var d = document.getElementById('yourDivId');
d.style.position = "absolute";
d.style.left = x_pos+'px';
d.style.top = y_pos+'px';

Or do it as a function so you can attach it to an event like onmousedown

function placeDiv(x_pos, y_pos) {
  var d = document.getElementById('yourDivId');
  d.style.position = "absolute";
  d.style.left = x_pos+'px';
  d.style.top = y_pos+'px';
}

There is no spoon.

Don't think of statelessness like "sending all your stuff to the server again and again". No way. There will be state, always - database itself is a kind of state after all, you're a registered user, so any set of client-side info won't be valid without the server side. Technically, you're never truly stateless.

The Login Debate

What does it even mean to not keep a session - and log in every time?

Some mean "send the password each time", that's just plain stupid. Some say "nah of course not, send a token instead" - lo and behold, PHP session is doing almost exactly that. It sends a session id which is a kind of token and it helps you reach your personal stuff without resending u/pw every time. It's also quite reliable and well tested. And yes, convenient, which can turn into a drawback, see next paragraph.

Reduce footprint

What you should do, instead, and what makes real sense, is thin your webserver footprint to the minimum. Languages like PHP make it very easy to just stuff everything in the session storage - but sessions have a price tag. If you have several webservers, they need to share session info, because they share the load too - any of them may have to serve the next request.



A shared storage is a must. Server needs to know at least if someone's logged in or not. (And if you bother the database every time you need to decide this, you're practically doomed.) Shared storages need to be a lot faster than the database. This brings the temptation: okay, I have a very fast storage, why not do everything there? - and that's where things go nasty in the other way.

So you're saying, keep session storage to the minimum?

Again, it's your decision. You can store stuff there for performance reasons (database is almost always slower than Redis), you can store information redundantly, implement your own caching, whatever - just keep in mind that web servers will have a bigger load if you store a lot of rubbish on them. Also, if they break under heavy loads (and they will), you lose valuable information; with the REST way of thinking, all that happens in this case is the client sends the same (!) request again and it gets served this time.

How to do it right then?

No one-fits-all solution here. I'd say choose a level of statelessness and go with that. Sessions may be loved by some and hated by others but they're not going anywhere. With every request, send as much information as makes sense, a bit more perhaps; but don't interpret statelessness as not having a session, nor as logging in every time. Somehow the server must know it's you; PHP session ids are one good way, manually generated tokens are another.

Think and decide - don't let design trends think for you.

I actually tried to implement connection pooling on the django end using:

https://github.com/gmcguire/django-db-pool

but I still received this error, despite lowering the number of connections available to below the standard development DB quota of 20 open connections.

There is an article here about how to move your postgresql database to the free/cheap tier of Amazon RDS. This would allow you to set max_connections higher. This will also allow you to pool connections at the database level using PGBouncer.

https://www.lewagon.com/blog/how-to-migrate-heroku-postgres-database-to-amazon-rds

UPDATE:

Heroku responded to my open ticket and stated that my database was improperly load balanced in their network. They said that improvements to their system should prevent similar problems in the future. Nonetheless, support manually relocated my database and performance is noticeably improved.

The answer given by CMS works fine with the following modification for null checks as well

function checkNested(obj /*, level1, level2, ... levelN*/) 
      {
             var args = Array.prototype.slice.call(arguments),
             obj = args.shift();

            for (var i = 0; i < args.length; i++) 
            {
                if (obj == null || !obj.hasOwnProperty(args[i]) ) 
                {
                    return false;
                }
                obj = obj[args[i]];
            }
            return true;
    }

As a side note: If your intranet users also have access to the Internet, you can use the SlideShare widget to embed your PowerPoint presentations in your website.

If you need run thread predioticly with different codes here is example:

Listener:

public interface ESLThreadListener {

    public List onBackground();

    public void onPostExecute(List list);

}

Thread Class

public class ESLThread extends AsyncTask<Void, Void, List> {


    private ESLThreadListener mListener;

    public ESLThread() {

        if(mListener != null){

            mListener.onBackground();
        }
    }

    @Override
    protected List doInBackground(Void... params) {

        if(mListener != null){

            List list = mListener.onBackground();

            return list;
        }

        return null;
    }

    @Override
    protected void onPostExecute(List t) {
        if(mListener != null){

            if ( t != null) {
                mListener.onPostExecute(t);
            }
        }

    }


    public void setListener(ESLThreadListener mListener){

        this.mListener = mListener;
    }
}

Run different codes:

  ESLThread thread = new ESLThread();
                        thread.setListener(new ESLThreadListener() {
                            @Override
                            public List onBackground() {
                                List<EntityShoppingListItems>  data = RoomDB.getDatabase(context).sliDAO().getSL(fId);

                                return data;

                            }

                            @Override
                            public void onPostExecute(List t) {

                                List<EntityShoppingListItems> data = (List<EntityShoppingListItems>)t;
                                adapter.setList(data);
                            }
                        });

                        thread.execute();

You need to declare @font-face like this in your stylesheet

@font-face {
  font-family: 'Awesome-Font';
  font-style: normal;
  font-weight: 400;
  src: local('Awesome-Font'), local('Awesome-Font-Regular'), url(path/Awesome-Font.woff) format('woff');
}

Now if you want to apply this font to a paragraph simply use it like this..

p {
font-family: 'Awesome-Font', Arial;
}

Call cURL from your console app is not a good idea.

But you can use TinyRestClient which make easier to build requests :

var client = new TinyRestClient(new HttpClient(),"https://api.repustate.com/");

client.PostRequest("v2/demokey/score.json").
AddQueryParameter("text", "").
ExecuteAsync<MyResponse>();

I created UIView and set the property of cell selectedBackgroundView:

UIView *v = [[UIView alloc] init];
v.backgroundColor = [UIColor redColor];
cell.selectedBackgroundView = v;

This will remove the margin and padding from your page elements, since there is a paragraph with a script inside that is causing an added margin. this way you should reset it and then you can style the other elements of your page, or you could give that paragraph an id and set margin to zero only for it.

<style>
* {
   margin: 0;
   padding: 0;
}
</style>

Try to put this as the first style.

Use a subselect:

SELECT row  FROM table  WHERE id=(
    SELECT max(id) FROM table
)

Note: ID must be unique, else multiple rows are returned

For a VB or C# app, one way to do this is by using Office Interop. This depends on which version of Excel you're working with.

For Excel 2003, this MSDN article is a good place to start. Understanding the Excel Object Model from a Visual Studio 2005 Developer's Perspective

You'll basically need to do the following:

• Start the Excel application.
• Open the Excel workbook.
• Retrieve the worksheet from the workbook by name or index.
• Iterate through all the Cells in the worksheet which were retrieved as a range.
• Sample (untested) code excerpt below for the last step.

    Excel.Range allCellsRng;
    string lowerRightCell = "IV65536";
    allCellsRng = ws.get_Range("A1", lowerRightCell).Cells;
    foreach (Range cell in allCellsRng)
    {
        if (null == cell.Value2 || isBlank(cell.Value2))
        {
          // Do something.
        }
        else if (isText(cell.Value2))
        {
          // Do something.
        }
        else if (isNumeric(cell.Value2))
        {
          // Do something.
        }
    }

For Excel 2007, try this MSDN reference.

Directory.GetParent is probably a better answer, but for completeness there's a different method that takes string and returns string: Path.GetDirectoryName.

string parent = System.IO.Path.GetDirectoryName(str_directory);

you can always execute SQL.

update [your table] set [your column]=value

for example

update Foo set Bar=125

It's ugly, but it works. :/

var today = new Date().toLocaleString('en-GB').split(' ')[0].split('/').reverse().join('-');

Reflection is to let object to see their appearance. This argument seems nothing to do with reflection. In fact, this is the "self-identify" ability.

Reflection itself is a word for such languages that lack the capability of self-knowledge and self-sensing as Java and C#. Because they do not have the capability of self-knowledge, when we want to observe how it looks like, we must have another thing to reflect on how it looks like. Excellent dynamic languages such as Ruby and Python can perceive the reflection of their own without the help of other individuals. We can say that the object of Java cannot perceive how it looks like without a mirror, which is an object of the reflection class, but an object in Python can perceive it without a mirror. So that's why we need reflection in Java.

You can get this if the client specifies "https" but the server is only running "http". So, the server isn't expecting to make a secure connection.

For python2 you can also do this

'%(author)s in %(publication)s'%{'author':unicode(self.author),
                                  'publication':unicode(self.publication)}

which is handy if you have a lot of arguments to substitute (particularly if you are doing internationalisation)

Python2.6 onwards supports .format()

'{author} in {publication}'.format(author=self.author,
                                   publication=self.publication)

For this case word boundary (\b) can also be used instead of start anchor (^) and end anchor ($):

\b\d{1,45}\b

\b is a position between \w and \W (non-word char), or at the beginning or end of a string.

You can use your own isEmpty (for multiple collection) method too. Add this your Util class.

public static boolean isEmpty(Collection... collections) {
    for (Collection collection : collections) {
        if (null == collection || collection.isEmpty())
            return true;
    }
    return false;
}

Just select the order yourself by typing in the column names. Note the double brackets:

frame = frame[['column I want first', 'column I want second'...etc.]]

Install Both of the below links

1. Windows Identity Foundation

   Note: (For Vista and Windows Server 2008 >>> Windows6.0 and For Windows 7 and Windows Server 2008 R2, >>> Windows6.1. )

2. Windows Identity Foundation SDK

   Note: Download the 3.5 version for Visual Studio 2008 and .NET 3.5, the 4.0 version for Visual Studio 2010 and .NET 4.0.

Then Only, You will able to get the assembly called Microsoft.IdentityModel

Instead of using long command like

php artisan make:model <Model Name> --migration --controller --resource

for make migration, model and controller, you may use even shorter as -mcr.

php artisan make:model <Model Name> -mcr

For more MOST USEFUL LARAVEL ARTISAN MAKE COMMANDS LISTS

• Delete All folders you have created previously
• Create fresh folder
• Then try navigate to that folder from command "cd foldername"
• then try to install "npm install"

This will solve you problem.

You can use std::numeric_limits which is defined in <limits> to find the minimum or maximum value of types (As long as a specialization exists for the type). You can also use it to retrieve infinity (and put a - in front for negative infinity).

#include <limits>

//...

std::numeric_limits<float>::max();
std::numeric_limits<float>::min();
std::numeric_limits<float>::infinity();

As noted in the comments, min() returns the lowest possible positive value. In other words the positive value closest to 0 that can be represented. The lowest possible value is the negative of the maximum possible value.

There is of course the std::max_element and min_element functions (defined in <algorithm>) which may be a better choice for finding the largest or smallest value in an array.

Given:

String[] a = new String[] { "Hello", "World", "!" };

Then as an alternative to coobird's answer, where the glue is ", ":

Arrays.asList(a).toString().replaceAll("^\\[|\\]$", "")

Or to concatenate with a different string, such as " & ".

Arrays.asList(a).toString().replaceAll(", ", " & ").replaceAll("^\\[|\\]$", "")

However... this one ONLY works if you know that the values in the array or list DO NOT contain the character string ", ".

Using executeUpdate() on the Query API is faster because it bypasses the persistent context .However , by-passing persistent context would cause the state of instance in the memory and the actual values of that record in the DB are not synchronized.

Consider the following example :

 Employee employee= (Employee)entityManager.find(Employee.class , 1);
 entityManager
     .createQuery("update Employee set name = \'xxxx\' where id=1")
     .executeUpdate();

After flushing, the name in the DB is updated to the new value but the employee instance in the memory still keeps the original value .You have to call entityManager.refresh(employee) to reload the updated name from the DB to the employee instance.It sounds strange if your codes still have to manipulate the employee instance after flushing but you forget to refresh() the employee instance as the employee instance still contains the original values.

Normally , executeUpdate() is used in the bulk update process as it is faster due to bypassing the persistent context

The right way to update an entity is that you just set the properties you want to updated through the setters and let the JPA to generate the update SQL for you during flushing instead of writing it manually.

   Employee employee= (Employee)entityManager.find(Employee.class ,1);
   employee.setName("Updated Name");

//Declare the pointer and asign it to the function
bool (*pFunc)() = A;
//Call the function A
pFunc();
//Call function B
pFunc = B;
pFunc();
//Call function C
pFunc = C;
pFunc();

While configuring idea plugin in gradle, you should define output directories as follows.

idea{
    module{
        inheritOutputDirs = false
        outputDir = compileJava.destinationDir
        testOutputDir = compileTestJava.destinationDir
    }
}

You can try this

$('#select_id').select2({ minimumResultsForSearch: -1 });

it closes the search results box and then set control unvisible

You can check here in select2 document select2 documents

The original answer of ????? ???????? had an issue, so on the last cell collection view was scrolling to the beginning

func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    targetContentOffset.pointee = scrollView.contentOffset
    var indexes = yourCollectionView.indexPathsForVisibleItems
    indexes.sort()
    var index = indexes.first!
    // if velocity.x > 0 && (Get the number of items from your data) > index.row + 1 {
    if velocity.x > 0 && yourCollectionView.numberOfItems(inSection: 0) > index.row + 1 {
       index.row += 1
    } else if velocity.x == 0 {
        let cell = yourCollectionView.cellForItem(at: index)!
        let position = yourCollectionView.contentOffset.x - cell.frame.origin.x
        if position > cell.frame.size.width / 2 {
           index.row += 1
        }
    }
    
    yourCollectionView.scrollToItem(at: index, at: .centeredHorizontally, animated: true )
}

For cases where you use pandas.DataFrame.hist:

plt = df.Column_A.hist(bins=10)

Note that you get an ARRAY of plots, rather than a plot. Thus to set the x label you will need to do something like this

plt[0][0].set_xlabel("column A")

I use always:

• quality in 85
• progressive (comprobed compression)
• a very tiny gausssian blur to optimize the size (0.05 or 0.5 of radius) depends on the quality and size of the picture, this notably optimizes the size of the jpeg.
• Strip any comment or EXIF metadata

in imagemagick should be

convert -strip -interlace Plane -gaussian-blur 0.05 -quality 85% source.jpg result.jpg

or in the newer version:

magick source.jpg -strip -interlace Plane -gaussian-blur 0.05 -quality 85% result.jpg

Source.

From @Fordi in the comments (Don't forget to upvote him if you like this): If you dislike blurring, use -sampling-factor 4:2:0 instead. What this does is reduce the chroma channel's resolution to half, without messing with the luminance resolution that your eyes latch onto. If you want better fidelity in the conversion, you can get a slight improvement without an increase in filesize by specifying -define jpeg:dct-method=float - that is, use the more accurate floating point discrete cosine transform, rather than the default fast integer version.

My solution was to remove the Eclipse ADT plugin via menu "Help > About Eclipse SDK > Installation Details". Eclipse will restart.

Next go to Menu "Help > Install New Software", then add the ADT plugin url "https://dl-ssl.google.com/android/eclipse" (or select the existing link from the dropdown).

This will re-install the latest ADT, including the DDMS files.

As Jim Garrison said in the comment, no obvious reason why you'd make a one-element list out of drug.upper() (which implies drug is a string).

But that's not your error, as your function medications_minimum3() doesn't even use the second argument (something you should fix).

TypeError: unhashable type: 'list' usually means that you are trying to use a list as a hash argument (like for accessing a dictionary). I'd look for the error in counter[row[11]]+=1 -- are you sure that row[11] is of the right type? Sounds to me it might be a list.

How about ioreg? The output's much more detailed than the profiler, but it's a bit dense.

Here's how to determine a local user:

    public bool IsLocalUser()
    {
        return windowsIdentity.AuthenticationType == "NTLM";
    }

Edit by Ian Boyd

You should not use NTLM anymore at all. It is so old, and so bad, that Microsoft's Application Verifier (which is used to catch common programming mistakes) will throw a warning if it detects you using NTLM.

Here's a chapter from the Application Verifier documentation about why they have a test if someone is mistakenly using NTLM:

Why the NTLM Plug-in is Needed

NTLM is an outdated authentication protocol with flaws that potentially compromise the security of applications and the operating system. The most important shortcoming is the lack of server authentication, which could allow an attacker to trick users into connecting to a spoofed server. As a corollary of missing server authentication, applications using NTLM can also be vulnerable to a type of attack known as a “reflection” attack. This latter allows an attacker to hijack a user’s authentication conversation to a legitimate server and use it to authenticate the attacker to the user’s computer. NTLM’s vulnerabilities and ways of exploiting them are the target of increasing research activity in the security community.

Although Kerberos has been available for many years many applications are still written to use NTLM only. This needlessly reduces the security of applications. Kerberos cannot however replace NTLM in all scenarios – principally those where a client needs to authenticate to systems that are not joined to a domain (a home network perhaps being the most common of these). The Negotiate security package allows a backwards-compatible compromise that uses Kerberos whenever possible and only reverts to NTLM when there is no other option. Switching code to use Negotiate instead of NTLM will significantly increase the security for our customers while introducing few or no application compatibilities. Negotiate by itself is not a silver bullet – there are cases where an attacker can force downgrade to NTLM but these are significantly more difficult to exploit. However, one immediate improvement is that applications written to use Negotiate correctly are automatically immune to NTLM reflection attacks.

By way of a final word of caution against use of NTLM: in future versions of Windows it will be possible to disable the use of NTLM at the operating system. If applications have a hard dependency on NTLM they will simply fail to authenticate when NTLM is disabled.

How the Plug-in Works

The Verifier plug detects the following errors:

• The NTLM package is directly specified in the call to AcquireCredentialsHandle (or higher level wrapper API).

• The target name in the call to InitializeSecurityContext is NULL.

• The target name in the call to InitializeSecurityContext is not a properly-formed SPN, UPN or NetBIOS-style domain name.

The latter two cases will force Negotiate to fall back to NTLM either directly (the first case) or indirectly (the domain controller will return a “principal not found” error in the second case causing Negotiate to fall back).

The plug-in also logs warnings when it detects downgrades to NTLM; for example, when an SPN is not found by the Domain Controller. These are only logged as warnings since they are often legitimate cases – for example, when authenticating to a system that is not domain-joined.

NTLM Stops

5000 – Application Has Explicitly Selected NTLM Package

Severity – Error

The application or subsystem explicitly selects NTLM instead of Negotiate in the call to AcquireCredentialsHandle. Even though it may be possible for the client and server to authenticate using Kerberos this is prevented by the explicit selection of NTLM.

How to Fix this Error

The fix for this error is to select the Negotiate package in place of NTLM. How this is done will depend on the particular Network subsystem being used by the client or server. Some examples are given below. You should consult the documentation on the particular library or API set that you are using.

APIs(parameter) Used by Application    Incorrect Value  Correct Value  
=====================================  ===============  ========================
AcquireCredentialsHandle (pszPackage)  “NTLM”           NEGOSSP_NAME “Negotiate”

This is a variation on hexacyanide's answer above. This middleware also handles the 'data' event but does not wait for the data to be consumed before calling 'next'. This way both this middleware and bodyParser may coexist, consuming the stream in parallel.

app.use(function(req, res, next) {
  req.rawBody = '';
  req.setEncoding('utf8');

  req.on('data', function(chunk) { 
    req.rawBody += chunk;
  });

  next();
});
app.use(express.bodyParser());

If you don't mind using 3rd party libraries, my cyclops-react lib has extensions for all JDK Collection types, including Map. You can directly use the map or bimap methods to transform your Map. A MapX can be constructed from an existing Map eg.

  MapX<String, Column> y = MapX.fromMap(orgColumnMap)
                               .map(c->new Column(c.getValue());

If you also wish to change the key you can write

  MapX<String, Column> y = MapX.fromMap(orgColumnMap)
                               .bimap(this::newKey,c->new Column(c.getValue());

bimap can be used to transform the keys and values at the same time.

As MapX extends Map the generated map can also be defined as

  Map<String, Column> y

You can do this by displaying a div (if you want to do it in a modal manner you could use blockUI - or one of the many other modal dialog plugins out there) prior to the request then just waiting until the call back succeeds as a quick example you can you $.getJSON as follows (you might want to use .ajax if you want to add proper error handling)

$("#ajaxLoader").show(); //Or whatever you want to do
$.getJSON("/AJson/Call/ThatTakes/Ages", function(result) {
    //Process your response
    $("#ajaxLoader").hide();
});

If you do this several times in your app and want to centralise the behaviour for all ajax calls you can make use of the global AJAX events:-

$("#ajaxLoader").ajaxStart(function() { $(this).show(); })
               .ajaxStop(function() { $(this).hide(); });

Using blockUI is similar for example with mark up like:-

<a href="/Path/ToYourJson/Action" id="jsonLink">Get JSON</a>
<div id="resultContainer" style="display:none">
And the answer is:-
    <p id="result"></p>
</div>

<div id="ajaxLoader" style="display:none">
    <h2>Please wait</h2>
    <p>I'm getting my AJAX on!</p>
</div>

And using jQuery:-

$(function() {
    $("#jsonLink").click(function(e) {
        $.post(this.href, function(result) {
            $("#resultContainer").fadeIn();
            $("#result").text(result.Answer);
        }, "json");
        return false;
    });
    $("#ajaxLoader").ajaxStart(function() {
                          $.blockUI({ message: $("#ajaxLoader") });
                     })
                    .ajaxStop(function() { 
                          $.unblockUI();
                     });
});

The guys have given the simple solution, which will do be you should have a look at the help - it's good, looks like a lot in one go but it's actually quick to read:

I had the same problem. Mine was due to a third jar, but the logcat did not catch the exception, i solved by update the third jar, hope these will help.

Go to android studio setting (by pressing Ctrl+Alt+S in windows), search for Instant Run and uncheck Enable Instant Run.

By disabling Instant Run and running your application again, problem will be resolved.

Select "all project" and right click

Maven-> Update project

I don't know if this is what you're looking for, but you can export the results to Excel like this:

In the results pane, click the top-left cell to highlight all the records, and then right-click the top-left cell and click "Save Results As". One of the export options is CSV.

You might give this a shot too:

INSERT INTO OPENROWSET 
   ('Microsoft.Jet.OLEDB.4.0', 
   'Excel 8.0;Database=c:\Test.xls;','SELECT productid, price FROM dbo.product')

Lastly, you can look into using SSIS (replaced DTS) for data exports. Here is a link to a tutorial:

http://www.accelebrate.com/sql_training/ssis_2008_tutorial.htm

== Update #1 ==

To save the result as CSV file with column headers, one can follow the steps shown below:

1. Go to Tools->Options
2. Query Results->SQL Server->Results to Grid
3. Check “Include column headers when copying or saving results”
4. Click OK.
5. Note that the new settings won’t affect any existing Query tabs — you’ll need to open new ones and/or restart SSMS.

With the below code you have to set PermissionLevel=External on your project properties before you deploy, and change the database to trust external code (be sure to read elsewhere about security risks and alternatives [like certificates]) by running "ALTER DATABASE database_name SET TRUSTWORTHY ON".

using System;
using System.Collections.Generic;
using System.Data.SqlTypes;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using Microsoft.SqlServer.Server;

[Serializable]
[SqlUserDefinedAggregate(Format.UserDefined,
MaxByteSize=8000,
IsInvariantToDuplicates=true,
IsInvariantToNulls=true,
IsInvariantToOrder=true,
IsNullIfEmpty=true)]
    public struct CommaDelimit : IBinarySerialize
{


[Serializable]
 private class StringList : List<string>
 { }

 private StringList List;

 public void Init()
 {
  this.List = new StringList();
 }

 public void Accumulate(SqlString value)
 {
  if (!value.IsNull)
   this.Add(value.Value);
 }

 private void Add(string value)
 {
  if (!this.List.Contains(value))
   this.List.Add(value);
 }

 public void Merge(CommaDelimit group)
 {
  foreach (string s in group.List)
  {
   this.Add(s);
  }
 }

 void IBinarySerialize.Read(BinaryReader reader)
 {
    IFormatter formatter = new BinaryFormatter();
    this.List = (StringList)formatter.Deserialize(reader.BaseStream);
 }

 public SqlString Terminate()
 {
  if (this.List.Count == 0)
   return SqlString.Null;

  const string Separator = ", ";

  this.List.Sort();

  return new SqlString(String.Join(Separator, this.List.ToArray()));
 }

 void IBinarySerialize.Write(BinaryWriter writer)
 {
  IFormatter formatter = new BinaryFormatter();
  formatter.Serialize(writer.BaseStream, this.List);
 }
    }

I've tested this using a query that looks like:

SELECT 
 dbo.CommaDelimit(X.value) [delimited] 
FROM 
 (
  SELECT 'D' [value] 
  UNION ALL SELECT 'B' [value] 
  UNION ALL SELECT 'B' [value] -- intentional duplicate
  UNION ALL SELECT 'A' [value] 
  UNION ALL SELECT 'C' [value] 
 ) X 

And yields: A, B, C, D

Yes it will return null if it's not present you can try this below in the demo. Both will return true. The first elements exists the second doesn't.

Demo

Html

<div id="xx"></div>

Javascript:

   if (document.getElementById('xx') !=null) 
     console.log('it exists!');

   if (document.getElementById('xxThisisNotAnElementOnThePage') ==null) 
     console.log('does not exist!');

NUMBER (precision, scale)

If a precision is not specified, the column stores values as given. If no scale is specified, the scale is zero.

Adding two Int16 values result in an Int32 value. You will have to cast it to Int16:

Int16 answer = (Int16) (firstNo + secondNo);

You can avoid this problem by switching all your numbers to Int32.

Both C# and Java don't have plain functions only member functions (aka methods). And the methods are not first-class citizens. First-class functions allow us to create beautiful and powerful code, as seen in F# or Clojure languages. (For instance, first-class functions can be passed as parameters and can return functions.) Java and C# ameliorate this somewhat with interfaces/delegates.

Func<int, int, int> randInt = (n1, n2) => new Random().Next(n1, n2); 

So, Func is a built-in delegate which brings some functional programming features and helps reduce code verbosity.

Complementing the @DanielLew answer, to get the values of the parameteres you have to do this:

URI example: myapp://path/to/what/i/want?keyOne=valueOne&keyTwo=valueTwo

in your activity:

Intent intent = getIntent();
if (Intent.ACTION_VIEW.equals(intent.getAction())) {
  Uri uri = intent.getData();
  String valueOne = uri.getQueryParameter("keyOne");
  String valueTwo = uri.getQueryParameter("keyTwo");
}

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
double width = screenSize.getWidth();
double height = screenSize.getHeight();
framemain.setSize((int)width,(int)height);
framemain.setResizable(true);
framemain.setExtendedState(JFrame.MAXIMIZED_BOTH);

Extra Tips:

Multiple "nots", input that is NOT hidden and NOT disabled:

:not([type="hidden"]):not([disabled])

Also did you know you can do this:

node.parentNode.querySelectorAll('div');

This is equivelent to jQuery's:

$(node).parent().find('div');

Which will effectively find all divs in "node" and below recursively, HOT DAMN!

Use

RefreshForm.submit(); 

instead of

document.location.reload(true); 

=$G1="X"

would be the correct (and easiest) method. Just select the entire sheet first, as conditional formatting only works on selected cells. I just tried it and it works perfectly. You must start at G1 rather than G2 otherwise it will offset the conditional formatting by a row.

You can get this using Emulation (Ctrl + 8) Document mode (10,9,8,7,5), Browser Profile (Desktop, Windows Phone)
