A little math can give you a one-line function:

function zeroFill( number, width ) {
  return Array(width - parseInt(Math.log(number)/Math.LN10) ).join('0') + number;
}

That's assuming that number is an integer no wider than width. If the calling routine can't make that guarantee, the function will need to make some checks:

function zeroFill( number, width ) {
    var n = width - parseInt(Math.log(number)/Math.LN10);
    return (n < 0) ? '' + number : Array(n).join('0') + number;
}

I am currently creating plugins for a retail software brand, which are actually .net class libraries. As a requirement, each plugin needs to be configured using a config file. After a bit of research and testing, I compiled the following class. It does the job flawlessly. Note that I haven't implemented local exception handling in my case because, I catch exceptions at a higher level.

Some tweaking maybe needed to get the decimal point right, in case of decimals and doubles, but it works fine for my CultureInfo...

static class Settings
{
    static UriBuilder uri = new UriBuilder(Assembly.GetExecutingAssembly().CodeBase);
    static Configuration myDllConfig = ConfigurationManager.OpenExeConfiguration(uri.Path);
    static AppSettingsSection AppSettings = (AppSettingsSection)myDllConfig.GetSection("appSettings");
    static NumberFormatInfo nfi = new NumberFormatInfo() 
    { 
        NumberGroupSeparator = "", 
        CurrencyDecimalSeparator = "." 
    };

    public static T Setting<T>(string name)
    {
        return (T)Convert.ChangeType(AppSettings.Settings[name].Value, typeof(T), nfi);
    }
}

App.Config file sample

<add key="Enabled" value="true" />
<add key="ExportPath" value="c:\" />
<add key="Seconds" value="25" />
<add key="Ratio" value="0.14" />

Usage:

  somebooleanvar = Settings.Setting<bool>("Enabled");
  somestringlvar = Settings.Setting<string>("ExportPath");
  someintvar =     Settings.Setting<int>("Seconds");
  somedoublevar =  Settings.Setting<double>("Ratio");

I have had same problem with my scripts. But when I did some modifications it worked for me. I did like this :-

export k=$(date "+%k");
if [ $k -ge 16 ] 
    then exit 0; 
else 
    echo "good job for nothing"; 
fi;

that way I resolved my problem. Hope that will help for you too.

<table>
  <tbody>
    <tr><td>{{data[0].foo}}</td></tr>
    <tr ng-repeat="d in data[1]"><td>{{d.bar}}</td></tr>
    <tr ng-repeat="d in data[2]"><td>{{d.lol}}</td></tr>
  </tbody>
</table>

I think that this is valid :)

selection -selecting a particular item(the lowest) and swap it with the i(no of iteration)th element. (i.e,first,second,third.......) hence,making the sorted list on one side.

insertion- comparing first with second compare third with second & first compare fourth with third,second & first......

a link where all sortings are compared

This is Daria's suggestion (see comment on the question) which works starting from TypeScript 2.1 and basically clones each element from the array:

this.clonedArray = theArray.map(e => ({ ... e }));

Hi try this it will create directory + file inside it

File mediaDir = new File("/sdcard/download/media");
if (!mediaDir.exists()){
    mediaDir.mkdir();
}

File resolveMeSDCard = new File("/sdcard/download/media/hello_file.txt");
resolveMeSDCard.createNewFile();
FileOutputStream fos = new FileOutputStream(resolveMeSDCard);
fos.write(string.getBytes());
fos.close();

System.out.println("Your file has been written");  

Java converts Integer to int and back automatically (unless you are still with Java 1.4).

In ES6 use:

import path from 'path';
const __dirname = path.resolve();

also available when node is called with --experimental-modules

The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:

import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square') 
plt.xlabel('x')
plt.ylabel('y') 
plt.xticks(xi, x)
plt.title('compare')
plt.legend() 
plt.show()

A method you can use is itertuples(), it iterates over DataFrame rows as namedtuples, with index value as first element of the tuple. And it is much much faster compared with iterrows(). For itertuples(), each row contains its Index in the DataFrame, and you can use loc to set the value.

for row in df.itertuples():
    if <something>:
        df.at[row.Index, 'ifor'] = x
    else:
        df.at[row.Index, 'ifor'] = x

    df.loc[row.Index, 'ifor'] = x

Under most cases, itertuples() is faster than iat or at.

Thanks @SantiStSupery, using .at is much faster than loc.

You can use var_dump or print_r functions on Blade themplate via Controller functions :

class myController{

   public function showView(){
     return view('myView',["myController"=>$this]);
   }
   public function myprint($obj){
     echo "<pre>";
     print_r($obj);
     echo "</pre>";
   }
}

And use your blade themplate :

$myController->myprint($users);

When you're serving an .ico file to be used as a favicon, it doesn't matter. All major browsers recognize both mime types correctly. So you could put:

<!-- IE -->
<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
<!-- other browsers -->
<link rel="icon" type="image/x-icon" href="favicon.ico" />

or the same with image/vnd.microsoft.icon, and it will work with all browsers.

Note: There is no IANA specification for the MIME-type image/x-icon, so it does appear that it is a little more unofficial than image/vnd.microsoft.icon.

The only case in which there is a difference is if you were trying to use an .ico file in an <img> tag (which is pretty unusual). Based on previous testing, some browsers would only display .ico files as images when they were served with the MIME-type image/x-icon. More recent tests show: Chromium, Firefox and Edge are fine with both content types, IE11 is not. If you can, just avoid using ico files as images, use png.

I got the same error with a class like the following StockPickBean. Called from this code:

List<StockPickBean> beansListcatMap.getValue();
beansList.sort(StockPickBean.Comparators.VALUE);

public class StockPickBean implements Comparable<StockPickBean> {
    private double value;
    public double getValue() { return value; }
    public void setValue(double value) { this.value = value; }

    @Override
    public int compareTo(StockPickBean view) {
        return Comparators.VALUE.compare(this,view); //return 
        Comparators.SYMBOL.compare(this,view);
    }

    public static class Comparators {
        public static Comparator<StockPickBean> VALUE = (val1, val2) -> 
(int) 
         (val1.value - val2.value);
    }
}

After getting the same error:

java.lang.IllegalArgumentException: Comparison method violates its general contract!

I changed this line:

public static Comparator<StockPickBean> VALUE = (val1, val2) -> (int) 
         (val1.value - val2.value);

to:

public static Comparator<StockPickBean> VALUE = (StockPickBean spb1, 
StockPickBean spb2) -> Double.compare(spb2.value,spb1.value);

That fixes the error.

I have the practice (habit) of almost always initializing in the contructor for two reasons, one in my opinion it adds to readablitiy (cleaner), and two there is more logic control in the constructor than in one line. Even if initially the instance variable doesn't require logic, having it in the constructor gives more flexibility to add logic in the future if needed.

As to the concern mentioned above about multiple constructors, that's easily solved by having one no-arg constructor that initializes all the instance variables that are initilized the same for all constructors and then each constructor calls this() at the first line. That solves your reduncancy issues.

In order to do this for multiple items do something like:

foreach (var item in Model)
{
    @Html.RadioButtonFor(m => m.item, "Yes") @:Yes
    @Html.RadioButtonFor(m => m.item, "No") @:No
}

For a shopping cart situation here's what I recommend. I'm gonna break it down into it's simplest form.

Assuming we start with this(a list view with 2 colums, 2 buttons, and a label):

First things first, removing the items, to do that we'll enter our remove button:

private void button2_Click(object sender, EventArgs e)
{
    listView1.Items.Remove(listView1.SelectedItems[0]);
    label1.Text = updateCartTotal().ToString();
}

Now the second line is updating our labels total using the next function i'll post to addup all the total of column 2 in the listview:

private decimal updateCartTotal()
{
    decimal runningTotal = 0;
    foreach(ListViewItem l in listView1.Items)
    {
        runningTotal += Convert.ToDecimal(l.SubItems[1].Text);
    }
    return runningTotal;
}

You don't have to use decimal like I did, you can use float or int if you don't have decimals. So let's break it down. We use a for loop to total all the items in the column 2(SubItems[1].Text). Add that to a decimal we declared prior to the foreach loop to keep a total. If you want to do tax you can do something like:

return runningTotal * 1.15;

or whatever your tax rate is.

Long and short of it, using this function you can retotal your listview by just calling the function. You can change the labels text like I demo'd prior if that's what you're after.

You need to add the path to environment variables (Windows) like such:

Variable Name: GRADLE_HOME
Variable Value: path

Hope this helps;

df1 = data.frame(CustomerId=c(1:10),
             Hobby = c(rep("sing", 4), rep("pingpong", 3), rep("hiking", 3)),

df3 = merge(df1, df2, by.x=c("CustomerId", "Hobby"), by.y=c("CustomerId", "like"))

Assuming df1$Hobby and df2$like mean the same thing.

I have faced this issue, but found an answer before finding this post :

Based on unutbu's answer, load your data...

import pandas as pd
import io

texts = ['''\
id   Name   score                    isEnrolled                       Date
111  Jack                            True              2013-05-01 12:00:00
112  Nick   1.11                     False             2013-05-12 15:05:23
     Zoe    4.12                     True                                  ''',

         '''\
id   Name   score                    isEnrolled                       Date
111  Jack   2.17                     True              2013-05-01 12:00:00
112  Nick   1.21                     False                                
     Zoe    4.12                     False             2013-05-01 12:00:00''']


df1 = pd.read_fwf(io.StringIO(texts[0]), widths=[5,7,25,17,20], parse_dates=[4])
df2 = pd.read_fwf(io.StringIO(texts[1]), widths=[5,7,25,17,20], parse_dates=[4])

...define your diff function...

def report_diff(x):
    return x[0] if x[0] == x[1] else '{} | {}'.format(*x)

Then you can simply use a Panel to conclude :

my_panel = pd.Panel(dict(df1=df1,df2=df2))
print my_panel.apply(report_diff, axis=0)

#          id  Name        score    isEnrolled                       Date
#0        111  Jack   nan | 2.17          True        2013-05-01 12:00:00
#1        112  Nick  1.11 | 1.21         False  2013-05-12 15:05:23 | NaT
#2  nan | nan   Zoe         4.12  True | False  NaT | 2013-05-01 12:00:00

By the way, if you're in IPython Notebook, you may like to use a colored diff function to give colors depending whether cells are different, equal or left/right null :

from IPython.display import HTML
pd.options.display.max_colwidth = 500  # You need this, otherwise pandas
#                          will limit your HTML strings to 50 characters

def report_diff(x):
    if x[0]==x[1]:
        return unicode(x[0].__str__())
    elif pd.isnull(x[0]) and pd.isnull(x[1]):
        return u'<table style="background-color:#00ff00;font-weight:bold;">'+\
            '<tr><td>%s</td></tr><tr><td>%s</td></tr></table>' % ('nan', 'nan')
    elif pd.isnull(x[0]) and ~pd.isnull(x[1]):
        return u'<table style="background-color:#ffff00;font-weight:bold;">'+\
            '<tr><td>%s</td></tr><tr><td>%s</td></tr></table>' % ('nan', x[1])
    elif ~pd.isnull(x[0]) and pd.isnull(x[1]):
        return u'<table style="background-color:#0000ff;font-weight:bold;">'+\
            '<tr><td>%s</td></tr><tr><td>%s</td></tr></table>' % (x[0],'nan')
    else:
        return u'<table style="background-color:#ff0000;font-weight:bold;">'+\
            '<tr><td>%s</td></tr><tr><td>%s</td></tr></table>' % (x[0], x[1])

HTML(my_panel.apply(report_diff, axis=0).to_html(escape=False))

Once I needed to resize photos from camera for developing:

• Original filesize: 2800 kB
• Resolution: 3264x2448

Command:

mogrify -quality "97%" -resize 2048x2048 -filter Lanczos -interlace Plane -gaussian-blur 0.05 

• Result filesize 753 kB
• Resolution 2048x2048

and I can't see any changes in full screen with my 1920x1080 resolution monitor. 2048 resolution is the best for developing 10 cm photos at maximum quality of 360 dpi. I don't want to strip it.

edit: I noticed that I even get much better results without blurring. Without blurring filesize is 50% of original, but quality is better (when zooming).

I think your issue is that Range("H18") doesn't contain a formula. Also, you could make your code more efficient by eliminating x. Instead, change your code to

Range("H18").GoalSeek Goal:=Range("H32").Value, ChangingCell:=Range("G18")

As per you said your both files are in same directory. 1. index.html and 2. style.css

I have copied your code and run it in my local machine its working fine there is no issues.

According to me your browser is not refreshing the file so you can refresh/reload the entire page by pressing CTRL + F5 in windows for mac CMD + R.

Try it if still getting problem then you can test it by using firebug tool for firefox.

For IE8 and Google Chrome you can check it by pressing F12 your developer tool will pop-up and you can see the Html and css.

Still you have any problem please comment so we can help you.

If you want to import a css file that should be treaded as less use this line:

.ie {
  @import (less) 'ie.css';
}

This is the correct way:

UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
activityIndicator.center = CGPointMake(self.view.frame.size.width / 2.0, self.view.frame.size.height / 2.0);
[self.view addSubview: activityIndicator];

[activityIndicator startAnimating];

[activityIndicator release];

Setup your autoresizing mask if you support rotation. Cheers!!!

Try to see, if the service "SQL Server (MSSQLSERVER)" it's started, this solved my problem.

BTW, do you plan to only permit the Latin alphabet, or do you also plan to try to validate Chinese, Arabic, Hindi, etc.?

As others have said, don't even try to do this. Step back and ask yourself what you are actually trying to accomplish. Then try to accomplish it without making any assumptions about what people's names are, or what they mean.

Better yet:

for i in xa*; do
    sed -i 's/asd/dfg/g' $i
done

because nobody knows how many files are there, and it's easy to break command line limits.

Here's what happens when there are too many files:

# grep -c aaa *
-bash: /bin/grep: Argument list too long
# for i in *; do grep -c aaa $i; done
0
... (output skipped)

ViewPager.setOnPageChangeListener is deprecated now. You now need to use ViewPager.addOnPageChangeListener instead.

for example,

viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {

        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
    });

public static class StringHelpers
{
    private static Dictionary<string, string> escapeMapping = new Dictionary<string, string>()
    {
        {"\"", @"\\\"""},
        {"\\\\", @"\\"},
        {"\a", @"\a"},
        {"\b", @"\b"},
        {"\f", @"\f"},
        {"\n", @"\n"},
        {"\r", @"\r"},
        {"\t", @"\t"},
        {"\v", @"\v"},
        {"\0", @"\0"},
    };

    private static Regex escapeRegex = new Regex(string.Join("|", escapeMapping.Keys.ToArray()));

    public static string Escape(this string s)
    {
        return escapeRegex.Replace(s, EscapeMatchEval);
    }

    private static string EscapeMatchEval(Match m)
    {
        if (escapeMapping.ContainsKey(m.Value))
        {
            return escapeMapping[m.Value];
        }
        return escapeMapping[Regex.Escape(m.Value)];
    }
}

You can also use Windows PowerShell with the following command:

if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {
    [System.Diagnostics.EventLog]::CreateEventSource($source, "Application")
}

Make sure to check that the source does not exist before calling CreateEventSource, otherwise it will throw an exception.

You're not allowed to change the contents of a string constant, which is what the first p points to. The second p is an array initialized with a string constant, and you can change its contents.

Another fancy possibility is...

User.where("id > :id", id: 100)

This feature allows you to create more comprehensible queries if you want to replace in multiple places, for example...

User.where("id > :id OR number > :number AND employee_id = :employee", id: 100, number: 102, employee: 1205)

This has more meaning than having a lot of ? on the query...

User.where("id > ? OR number > ? AND employee_id = ?", 100, 102, 1205)

Object does not have forEach, it belongs to Array prototype. If you want to iterate through each key-value pair in the object and take the values. You can do this:

Object.keys(a).forEach(function (key){
    console.log(a[key]);
});

Usage note: For an object v = {"cat":"large", "dog": "small", "bird": "tiny"};, Object.keys(v) gives you an array of the keys so you get ["cat","dog","bird"]

This doesn't need jquery, doesn't need to load the script async, needs no timer nor to have the loaded script set a value. I've tested it in FF, Chrome, and Safari.

<script>
        function loadScript(src) {
          return new Promise(function(resolve, reject) {

            let s = window.document.createElement("SCRIPT");

            s.onload = () => resolve(s);
            s.onerror = () => reject(new Error(src));
            s.src = src;
            // don't bounce to global handler on 404.
            s.addEventListener('error', function() {});
            window.document.head.append(s);
          }); 
        }   
                        
        let successCallback = (result) => {
          console.log(scriptUrl + " loaded.");
        }   
                        
        let failureCallback = (error) => {
          console.log("load failed: " + error.message);
        }   
                        
        loadScript(scriptUrl).then(successCallback, failureCallback);
</script>

using Jackson 2.6.0, this worked for me:

private static final ObjectMapper objectMapper = 
    new ObjectMapper()
        .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

and with setting:

@JsonIgnoreProperties(ignoreUnknown = true)

mysql default port is 3306 can you try putting it and then try

I've faced such an issue and dig tones of material. So, to avoid ugly iteration you can simply tune your hql:

You need to frame your query like this

select entity from Entity as entity where ...

Also check such case, it perfectly works for me:

public List<User> findByRole(String role) {

    Query query = sessionFactory.getCurrentSession().createQuery("select user from User user join user.userRoles where role_name=:role_name");
    query.setString("role_name", role);
    @SuppressWarnings("unchecked")
    List<User> users = (List<User>) query.list();
    return users;
}

So here we are extracting object from query, not a bunch of fields. Also it's looks much more pretty.

Python lists were not made to operate on the beginning of the list and are very ineffective at this operation.

While you can write

mylist = [1, 2 ,3 ,4]
mylist.pop(0)

It's very inefficient.

If you only want to delete items from your list, you can do this with del:

del mylist[:n]

Which is also really fast:

In [34]: %%timeit
help=range(10000)
while help:
    del help[:1000]
   ....:
10000 loops, best of 3: 161 µs per loop

If you need to obtain elements from the beginning of the list, you should use collections.deque by Raymond Hettinger and its popleft() method.

from collections import deque

deque(['f', 'g', 'h', 'i', 'j'])

>>> d.pop()                          # return and remove the rightmost item
'j'
>>> d.popleft()                      # return and remove the leftmost item
'f'

A comparison:

list + pop(0)

In [30]: %%timeit
   ....: help=range(10000)
   ....: while help:
   ....:     help.pop(0)
   ....:
100 loops, best of 3: 17.9 ms per loop

deque + popleft()

In [33]: %%timeit
help=deque(range(10000))
while help:
    help.popleft()
   ....:
1000 loops, best of 3: 812 µs per loop

Let's see how we get the params, headers and body in Flask. I'm gonna explain with the help of postman.

The params keys and values are reflected in the API endpoint. for example key1 and key2 in the endpoint : https://127.0.0.1/upload?key1=value1&key2=value2

from flask import Flask, request
app = Flask(__name__)

@app.route('/upload')
def upload():

  key_1 = request.args.get('key1')
  key_2 = request.args.get('key2')
  print(key_1)
  #--> value1
  print(key_2)
  #--> value2

After params, let's now see how to get the headers:

  header_1 = request.headers.get('header1')
  header_2 = request.headers.get('header2')
  print(header_1)
  #--> header_value1
  print(header_2)
  #--> header_value2

Now let's see how to get the body

  file_name = request.files['file'].filename
  ref_id = request.form['referenceId']
  print(ref_id)
  #--> WWB9838yb3r47484

so we fetch the uploaded files with request.files and text with request.form

Alternative and much easier way is to use shapes instead of 9-patches. It is already explained here: https://stackoverflow.com/a/24725831/512011

The command you're looking for is rem, short for "remark".

There is also a shorthand version :: that some people use, and this sort of looks like # if you squint a bit and look at it sideways. I originally preferred that variant since I'm a bash-aholic and I'm still trying to forget the painful days of BASIC :-)

Unfortunately, there are situations where :: stuffs up the command line processor (such as within complex if or for statements) so I generally use rem nowadays. In any case, it's a hack, suborning the label infrastructure to make it look like a comment when it really isn't. For example, try replacing rem with :: in the following example and see how it works out:

if 1==1 (
    rem comment line 1
    echo 1 equals 1
    rem comment line 2
)

You should also keep in mind that rem is a command, so you can't just bang it at the end of a line like the # in bash. It has to go where a command would go. For example, only the second of these two will echo the single word hello:

echo hello rem a comment.
echo hello & rem a comment.

I've managed to bind a custom model to an element at runtime. The code is here: http://jsfiddle.net/ZiglioNZ/tzD4T/457/

The interesting bit is that I apply the data-bind attribute to an element I didn't define:

    var handle = slider.slider().find(".ui-slider-handle").first();
    $(handle).attr("data-bind", "tooltip: viewModel.value");
    ko.applyBindings(viewModel.value, $(handle)[0]);

You can try this:

var entryArray = Array.prototype.slice.call(entry)

Ignoring the smooth interpolation between points in your example graph (that would require doing some manual interpolation, or just have a higher resolution of your data), you can use pyplot.fill_between():

from matplotlib import pyplot as plt
import numpy as np

x = np.linspace(0, 30, 30)
y = np.sin(x/6*np.pi)
error = np.random.normal(0.1, 0.02, size=y.shape)
y += np.random.normal(0, 0.1, size=y.shape)

plt.plot(x, y, 'k-')
plt.fill_between(x, y-error, y+error)
plt.show()

See also the matplotlib examples.

Here's a simple function that creates a CSS color string from RGB values ranging from 0 to 255:

function rgb(r, g, b){
  return "rgb("+r+","+g+","+b+")";
}

Alternatively (to create fewer string objects), you could use array join():

function rgb(r, g, b){
  return ["rgb(",r,",",g,",",b,")"].join("");
}

The above functions will only work properly if (r, g, and b) are integers between 0 and 255. If they are not integers, the color system will treat them as in the range from 0 to 1. To account for non-integer numbers, use the following:

function rgb(r, g, b){
  r = Math.floor(r);
  g = Math.floor(g);
  b = Math.floor(b);
  return ["rgb(",r,",",g,",",b,")"].join("");
}

You could also use ES6 language features:

const rgb = (r, g, b) => 
  `rgb(${Math.floor(r)},${Math.floor(g)},${Math.floor(b)})`;

All of this can easily be acheived in the xaml by adding the following code in the grid

<Grid>
    <Grid.Background>  
        <ImageBrush ImageSource="/MyProject;component/Images/bg.png"/>     
    </Grid.Background>
</Grid>

Left for you to do, is adding a folder to the solution called 'Images' and adding an existing file to your new 'Images' folder, in this case called 'bg.png'

The #1 answer has problems:

• Won't work on mac.
• If a file is installed which includes spaces or other special characters, the xargs command will fail, and delete any files/directories which matched the individual words.
• the -r in rm -rf is unnecessary and at worst could delete things you don't want to.

Instead, for unix-like:

sudo python setup.py install --record files.txt
# inspect files.txt to make sure it looks ok. Then:
tr '\n' '\0' < files.txt | xargs -0 sudo rm -f --

And for windows:

python setup.py bdist_wininst
dist/foo-1.0.win32.exe

There are also unsolvable problems with uninstalling setup.py install which won't bother you in a typical case. For a more complete answer, see this wiki page:

https://ofswiki.org/wiki/Uninstalling_setup.py_install

Code example of ItemListener implementation

class ItemChangeListener implements ItemListener{
    @Override
    public void itemStateChanged(ItemEvent event) {
       if (event.getStateChange() == ItemEvent.SELECTED) {
          Object item = event.getItem();
          // do something with object
       }
    }       
}

Now we will get only selected item.

Then just add listener to your JComboBox

addItemListener(new ItemChangeListener());

it is Cross-site scripting problem. Common modern browsers doesn't allow to send request to another url.

.Net Core does not require mono in the sense of the mono framework. .Net Core is a framework that will work on multiple platforms including Linux. Reference https://dotnet.github.io/.

However the .Net core can use the mono framework. Reference https://docs.asp.net/en/1.0.0-rc1/getting-started/choosing-the-right-dotnet.html (note rc1 documentatiopn no rc2 available), however mono is not a Microsoft supported framework and would recommend using a supported framework

Now entity framework 7 is now called Entity Framework Core and is available on multiple platforms including Linux. Reference https://github.com/aspnet/EntityFramework (review the road map)

I am currently using both of these frameworks however you must understand that it is still in release candidate stage (RC2 is the current version) and over the beta & release candidates there have been massive changes that usually end up with you scratching your head.

Here is a tutorial on how to install MVC .Net Core into Linux. https://docs.asp.net/en/1.0.0-rc1/getting-started/installing-on-linux.html

Finally you have a choice of Web Servers (where I am assuming the fast cgi reference came from) to host your application on Linux. Here is a reference point for installing to a Linux enviroment. https://docs.asp.net/en/1.0.0-rc1/publishing/linuxproduction.html

I realise this post ends up being mostly links to documentation but at this point those are your best sources of information. .Net core is still relatively new in the .Net community and until its fully released I would be hesitant to use it in a product environment given the breaking changes between released version.

In Spring there is a dedicated utility called ReflectionTestUtils for this purpose. Take the specific instance and inject into the the field.

@Spy

@Mock

@InjectMock
Foo foo;

@BeforeEach
void _before(){
   ReflectionTestUtils.setField(foo,"bar", new BarImpl());// `bar` is private field
}

If you want this without loops or jquery you could use the following This is straight up JavaScript. This works for current web browsers. Given the age of the question I am not sure if this would have worked back in 2011. Please note that using css style selectors is extremely powerful and can help shorten a lot of code.

// Please note that querySelectorAll will return a match for _x000D_
// for the term...if there is more than one then you will _x000D_
// have to loop through the returned object_x000D_
var selectAnimal = function() {_x000D_
  var animals = document.getElementById('animal');_x000D_
  if (animals) {_x000D_
    var x = animals.querySelectorAll('option[value="frog"]');_x000D_
    if (x.length === 1) {_x000D_
      console.log(x[0].index);_x000D_
      animals.selectedIndex = x[0].index;_x000D_
    }_x000D_
  }_x000D_
}

<html>_x000D_
_x000D_

  <title>Test without loop or jquery</title>_x000D_

document.getElementById('Animal').querySelectorAll('option[value="searchterm"]'); in the index object you can now do the following: x[0].index

I'm assuming you have a typo in your get statement and that it should be test1.get(key). If so, I'm not sure why it is not returning an ArrayList unless you are not putting in the correct type in the map in the first place.

This should work:

// populate the map
Map<String, List<String>> test1 = new LinkedHashMap<String, List<String>>();
test1.put("key1", new ArrayList<String>());
test1.put("key2", new ArrayList<String>());

// loop over the set using an entry set
for( Map.Entry<String,List<String>> entry : test1.entrySet()){
  String key = entry.getKey();
  List<String>value = entry.getValue();
  // ...
}

or you can use

// second alternative - loop over the keys and get the value per key
for( String key : test1.keySet() ){
  List<String>value = test1.get(key);
  // ...
}

You should use the interface names when declaring your vars (and in your generic params) unless you have a very specific reason why you are defining using the implementation.

Put this in your .vimrc configuration file.

One more way to select between dates in SQLite is to use the powerful strftime function:

SELECT * FROM test WHERE strftime('%Y-%m-%d', date) BETWEEN "11-01-2011" AND "11-08-2011"

These are equivalent according to https://sqlite.org/lang_datefunc.html:

date(...)

strftime('%Y-%m-%d', ...)

but if you want more choice, you have it.

Short answer (asked version): (format 3.33.20150710.182906)

Please, simple use a makefile with:

MAJOR = 3
MINOR = 33
BUILD = $(shell date +"%Y%m%d.%H%M%S")
VERSION = "\"$(MAJOR).$(MINOR).$(BUILD)\""
CPPFLAGS = -DVERSION=$(VERSION)

program.x : source.c
       gcc $(CPPFLAGS) source.c -o program.x

and if you don't want a makefile, shorter yet, just compile with:

gcc source.c -o program.x -DVERSION=\"2.22.$(date +"%Y%m%d.%H%M%S")\"

Short answer (suggested version): (format 150710.182906)

Use a double for version number:

MakeFile:

VERSION = $(shell date +"%g%m%d.%H%M%S")
CPPFLAGS = -DVERSION=$(VERSION)
program.x : source.c
      gcc $(CPPFLAGS) source.c -o program.x

Or a simple bash command:

$ gcc source.c -o program.x -DVERSION=$(date +"%g%m%d.%H%M%S")

Tip: Still don't like makefile or is it just for a not-so-small test program? Add this line:

 export CPPFLAGS='-DVERSION='$(date +"%g%m%d.%H%M%S")

to your ~/.profile, and remember compile with gcc $CPPFLAGS ...

Long answer:

I know this question is older, but I have a small contribution to make. Best practice is always automatize what otherwise can became a source of error (or oblivion).

I was used to a function that created the version number for me. But I prefer this function to return a float. My version number can be printed by: printf("%13.6f\n", version()); which issues something like: 150710.150411 (being Year (2 digits) month day DOT hour minute seconds).

But, well, the question is yours. If you prefer "major.minor.date.time", it will have to be a string. (Trust me, double is better. If you insist in a major, you can still use double if you set the major and let the decimals to be date+time, like: major.datetime = 1.150710150411

Lets get to business. The example bellow will work if you compile as usual, forgetting to set it, or use -DVERSION to set the version directly from shell, but better of all, I recommend the third option: use a makefile.

Three forms of compiling and the results:

Using make:

beco> make program.x
gcc -Wall -Wextra -g -O0 -ansi -pedantic-errors -c -DVERSION="\"3.33.20150710.045829\"" program.c -o program.o
gcc  program.o -o program.x

Running:

__DATE__: 'Jul 10 2015'
__TIME__: '04:58:29'
VERSION: '3.33.20150710.045829'

Using -DVERSION:

beco> gcc program.c -o program.x -Wall -Wextra -g -O0 -ansi -pedantic-errors -DVERSION=\"2.22.$(date +"%Y%m%d.%H%M%S")\"

Running:

__DATE__: 'Jul 10 2015'
__TIME__: '04:58:37'
VERSION: '2.22.20150710.045837'

Using the build-in function:

beco> gcc program.c -o program.x -Wall -Wextra -g -O0 -ansi -pedantic-errors

Running:

__DATE__: 'Jul 10 2015'
__TIME__: '04:58:43'
VERSION(): '1.11.20150710.045843'

Please note that the string is limited by MAJOR<=9999 and MINOR<=9999. Of course, I set this high value that will hopefully never overflow. But using double is still better (plus, it's completely automatic, no need to set MAJOR and MINOR by hand).

Now, the program above is a bit too much. Better is to remove the function completely, and guarantee that the macro VERSION is defined, either by -DVERSION directly into GCC command line (or an alias that automatically add it so you can't forget), or the recommended solution, to include this process into a makefile.

Here it is the makefile I use:

MakeFile source:

  1   MAJOR = 3
  2   MINOR = 33
  3   BUILD = $(shell date +"%Y%m%d.%H%M%S")
  4   VERSION = "\"$(MAJOR).$(MINOR).$(BUILD)\""
  5   CC = gcc
  6   CFLAGS = -Wall -Wextra -g -O0 -ansi -pedantic-errors
  7   CPPFLAGS = -DVERSION=$(VERSION)
  8   LDLIBS =
  9   
 10    %.x : %.c
 11          $(CC) $(CFLAGS) $(CPPFLAGS) $(LDLIBS) $^ -o $@

A better version with DOUBLE

Now that I presented you "your" preferred solution, here it is my solution:

Compile with (a) makefile or (b) gcc directly:

(a) MakeFile:

   VERSION = $(shell date +"%g%m%d.%H%M%S")
   CC = gcc
   CFLAGS = -Wall -Wextra -g -O0 -ansi -pedantic-errors 
   CPPFLAGS = -DVERSION=$(VERSION)
   LDLIBS =
   %.x : %.c
         $(CC) $(CFLAGS) $(CPPFLAGS) $(LDLIBS) $^ -o $@

(b) Or a simple bash command:

 $ gcc program.c -o program.x -Wall -Wextra -g -O0 -ansi -pedantic-errors -DVERSION=$(date +"%g%m%d.%H%M%S")

Source code (double version):

#ifndef VERSION
  #define VERSION version()
#endif

double version(void);

int main(void)
{
  printf("VERSION%s: '%13.6f'\n", (FUNC_VERSION?"()":""), VERSION);
  return 0;
}

double version(void)
{
  const char data[]=__DATE__;
  const char tempo[]=__TIME__;
  const char nomes[] = "JanFebMarAprMayJunJulAugSepOctNovDec";
  char omes[4];
  int ano, mes, dia, hora, min, seg;
  char sversion[]="130910.001339";
  double fv;

  if(strlen(data)!=11||strlen(tempo)!=8)
    return -1.0;

  sscanf(data, "%s %d %d", omes, &dia, &ano);
  sscanf(tempo, "%d:%d:%d", &hora, &min, &seg);
  mes=(strstr(nomes, omes)-nomes)/3+1;
  sprintf(sversion,"%04d%02d%02d.%02d%02d%02d", ano, mes, dia, hora, min, seg);
  fv=atof(sversion);

  return fv;
}

Note: this double function is there only in case you forget to define macro VERSION. If you use a makefile or set an alias gcc gcc -DVERSION=$(date +"%g%m%d.%H%M%S"), you can safely delete this function completely.

Well, that's it. A very neat and easy way to setup your version control and never worry about it again!

This is a simple, you can use spring boot maven plugin to finish your code deploy.

the plugin config like:

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <jvmArguments>-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=${debug.port}
                    </jvmArguments>
                    <profiles>
                        <profile>test</profile>
                    </profiles>
                    <executable>true</executable>
                </configuration>
            </plugin>

And, the jvmArtuments is add for you jvm. profiles will choose a profile to start your app. executable can make your app driectly run.

and if you add mvnw to your project, or you have a maven enveriment. You can just call./mvnw spring-boot:run for mvnw or mvn spring-boot:run for maven.

You may use numpy.append()...

import numpy

B = numpy.array([3])
A = numpy.array([1, 2, 2])
B = numpy.append( B , A )

print B

> [3 1 2 2]

This will not create two separate arrays but will append two arrays into a single dimensional array.

Just multiply the number by 100, round, and divide the resulting number by 100.

• Create a 'popup' directive and apply it to the container of the popup content
• In the directive, wrap the content in a absolute position div along with the mask div below it.
• It is OK to move the 2 divs in the DOM tree as needed from within the directive. Any UI code is OK in the directives, including the code to position the popup in center of screen.
• Create and bind a boolean flag to controller. This flag will control visibility.
• Create scope variables that bond to OK / Cancel functions etc.

Check out androPHP I use it for testing on android ANdroPHP.

I couldn't get David Chu's answer to work for a RecyclerView item and figured out I needed to constrain the ImageView to the parent. Set the ImageView width to 0dp and constrain its start and end to the parent. I'm not sure if setting the width to wrap_content or match_parent works in some cases, but I think this is a better way to get the child of a ConstraintLayout to fill its parent.

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <ImageView
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintDimensionRatio="1:1"/>

</android.support.constraint.ConstraintLayout>

suppose you have some elements and applied a class name 'test', so, you can get elements like as following

var tests = document.getElementsByClassName('test');

its returns an instance NodeList, or its superset: HTMLCollection (FF).

The main difference between the web containers and application server is that most web containers such as Apache Tomcat implements only basic JSR like Servlet, JSP, JSTL wheres Application servers implements the entire Java EE Specification. Every application server contains web container.

If I understand you need following code. (passing expression lambda by parameter) The Method

public static void Method(Expression<Func<int, bool>> predicate) { 
    int[] number={1,2,3,4,5,6,7,8,9,10};
    var newList = from x in number
                  .Where(predicate.Compile()) //here compile your clausuly
                  select x;
                newList.ToList();//return a new list
    }

Calling method

Method(v => v.Equals(1));

You can do the same in their class, see this is example.

public string Name {get;set;}

public static List<Class> GetList(Expression<Func<Class, bool>> predicate)
    {
        List<Class> c = new List<Class>();
        c.Add(new Class("name1"));
        c.Add(new Class("name2"));

        var f = from g in c.
                Where (predicate.Compile())
                select g;
        f.ToList();

       return f;
    }

Calling method

Class.GetList(c=>c.Name=="yourname");

I hope this is useful

I found a work around but with this I'll need to annotate each date's setter throughout the project. Is there a way in which I can specify the format while creating the ObjectMapper?

Here's what I did:

public class CustomJsonDateDeserializer extends JsonDeserializer<Date>
{
    @Override
    public Date deserialize(JsonParser jsonParser,
            DeserializationContext deserializationContext) throws IOException, JsonProcessingException {

        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
        String date = jsonParser.getText();
        try {
            return format.parse(date);
        } catch (ParseException e) {
            throw new RuntimeException(e);
        }

    }

And annotated each Date field's setter method with this:

@JsonDeserialize(using = CustomJsonDateDeserializer.class)

If you want to color your terminal console, then you can use npm package chalk

npm i chalk

Set the aaSorting option to an empty array. It will disable initial sorting, whilst still allowing manual sorting when you click on a column.

"aaSorting": []

The aaSorting array should contain an array for each column to be sorted initially containing the column's index and a direction string ('asc' or 'desc').

In the recent Python version, subprocess has a big change. It offers a brand-new class Popen to handle os.popen1|2|3|4.

The new subprocess.Popen()

import subprocess
subprocess.Popen('ls -la', shell=True)

Its arguments:

subprocess.Popen(args, 
                bufsize=0, 
                executable=None, 
                stdin=None, stdout=None, stderr=None, 
                preexec_fn=None, close_fds=False, 
                shell=False, 
                cwd=None, env=None, 
                universal_newlines=False, 
                startupinfo=None, 
                creationflags=0)

Simply put, the new Popen includes all the features which were split into 4 separate old popen.

The old popen:

Method  Arguments
popen   stdout
popen2  stdin, stdout
popen3  stdin, stdout, stderr
popen4  stdin, stdout and stderr

Issue can be solved by adding CRT of msvcrtd.lib in the linker library. Because cryptlib.lib used CRT version of debug.

For 3-D visualization pythreejs is the best way to go probably in the notebook. It leverages the interactive widget infrastructure of the notebook, so connection between the JS and python is seamless.

A more advanced library is bqplot which is a d3-based interactive viz library for the iPython notebook, but it only does 2D

FileReader reads from files on the file system.

Perhaps you intended to use something like this to load a file from the class path

// this will look in src/main/resources before building and myjar.jar! after building.
InputStream is = MyClass.class.getClassloader()
                     .getResourceAsStream("config.txt");

Or you could extract the file from the jar before reading it.

 $(this).css({'text-align':'center'}); 

You can use class name and id in place of this

$('.classname').css({'text-align':'center'});

or

$('#id').css({'text-align':'center'});

Add div wrapper

<div id=myForm>
<select name=countries>
 <option value=af>Afghanistan</option>
 <option value=ax>Åland Islands</option>
 ...
 <option value=gs>South Georgia and the South Sandwich Islands</option>
 ...
</select>
</div>

and then write CSS

#myForm select { 
width:200px; }

#myForm select:focus {
width:auto; }

Hope this will help.

A simple ddply option:

ddply(test,.(id),function(x) head(x,1))

If speed is an issue, a similar approach could be taken with data.table:

testd <- data.table(test)
setkey(testd,id)
testd[,.SD[1],by = key(testd)]

or this might be considerably faster:

testd[testd[, .I[1], by = key(testd]$V1]

Keep the h2 at the top, then pull-left on the p and pull-right on the login-box

<div class='container'>
  <div class='hero-unit'>

    <h2>Welcome</h2>

    <div class="pull-left">
      <p>Please log in</p>
    </div>

    <div id='login-box' class='pull-right control-group'>
        <div class='clearfix'>
            <input type='text' placeholder='Username' />
        </div>
        <div class='clearfix'>
            <input type='password' placeholder='Password' />
        </div>
        <button type='button' class='btn btn-primary'>Log in</button>
    </div>

    <div class="clearfix"></div>

  </div>
</div>

the default vertical-align on floated boxes is baseline, so the "Please log in" exactly lines up with the "Username" (check by changing the pull-right to pull-left).

If you have a complicated folder structure, such as

- Your application
     - assets
         - images
             - profile.jpg
     - web
     - server
        - index.js

If you want to serve assets/images from index.js

app.use('/images', express.static(path.join(__dirname, '..', 'assets', 'images')))

To view from your browser

http://localhost:4000/images/profile.jpg

If you need more clarification comment, I'll elaborate.

Assuming they do not have to be in IMG tags...

HTML:

<div class="thumb1">
</div>

CSS:

.thumb1 { 
  background: url(blah.jpg) 50% 50% no-repeat; /* 50% 50% centers image in div */
  width: 250px;
  height: 250px;
}

.thumb1:hover { YOUR HOVER STYLES HERE }

EDIT: If the div needs to link somewhere just adjust HTML and Styles like so:

HTML:

<div class="thumb1">
<a href="#">Link</a>
</div>

CSS:

.thumb1 { 
  background: url(blah.jpg) 50% 50% no-repeat; /* 50% 50% centers image in div */
  width: 250px;
  height: 250px;
}

.thumb1 a {
  display: block;
  width: 250px;
  height: 250px;
}

.thumb1 a:hover { YOUR HOVER STYLES HERE }

Note this could also be modified to be responsive, for example % widths and heights etc.

If I understand correctly, something has already sent out from header.php (maybe some HTML) so the headers have been set. You may need to recheck your header.php file for any part that may output HTML or spaces before your first

EDIT: I am now sure that it is caused from header.php since you have those HTML output. You can fix this by remove the "include('header.php');" line and copy the following code to your file instead.

include('class.user.php');
include('class.Connection.php');

        $date = date('Y-m-j');

<?php 
echo apply_filters( 'woocommerce_short_description', substr($post->post_excerpt, 0, 500) ) 
?>

Adding processData: false to the $.ajax options will fix this issue.

In addition to the above mentioned answers: I wanted to start a job with a simple parameter passed to a second pipeline and found the answer on http://web.archive.org/web/20160209062101/https://dzone.com/refcardz/continuous-delivery-with-jenkins-workflow

So i used:

stage ('Starting ART job') {
    build job: 'RunArtInTest', parameters: [[$class: 'StringParameterValue', name: 'systemname', value: systemname]]
}

Here's how you can get the surrounding dimentions:

var elem = $('#myId');

var marginTopBottom  = elem.outerHeight(true) - elem.outerHeight();
var marginLeftRight  = elem.outerWidth(true)  - elem.outerWidth();

var borderTopBottom  = elem.outerHeight() - elem.innerHeight();
var borderLeftRight  = elem.outerWidth()  - elem.innerWidth();

var paddingTopBottom  = elem.innerHeight() - elem.height();
var paddingLeftRight  = elem.innerWidth()  - elem.width();

Pay attention that each variable, paddingTopBottom for example, contains the sum of the margins on the both sides of the element; i.e., paddingTopBottom == paddingTop + paddingBottom. I wonder if there is a way to get them separately. Of course, if they are equal you can divide by 2 :)

Here is the cleanest way to do this:

<p ng-show="{{foo === undefined}}">Show this if $scope.foo === undefined</p>

No need to create a helper function in the controller!

I suppose you to use org.springframework.beans.factory.config.ServiceLocatorFactoryBean. It will much simplify your code. Except MyServiceAdapter u can only create interface MyServiceAdapter with method MyService getMyService and with alies to register your classes

Code

bean id="printStrategyFactory" class="org.springframework.beans.factory.config.ServiceLocatorFactoryBean">
        <property name="YourInterface" value="factory.MyServiceAdapter" />
    </bean>

    <alias name="myServiceOne" alias="one" />
    <alias name="myServiceTwo" alias="two" />

You could do something like this

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:6740/api/Membership/exist");

req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";         
req.ContentLength = 6;

StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();

And then strReponse should contain the values returned by your webservice

Here's an outline/boilerplate for describing the behavior of mapStateToProps:

(This is a vastly simplified implementation of what a Redux container does.)

class MyComponentContainer extends Component {
  mapStateToProps(state) {
    // this function is specific to this particular container
    return state.foo.bar;
  }

  render() {
    // This is how you get the current state from Redux,
    // and would be identical, no mater what mapStateToProps does
    const { state } = this.context.store.getState();

    const props = this.mapStateToProps(state);

    return <MyComponent {...this.props} {...props} />;
  }
}

and next

function buildReduxContainer(ChildComponentClass, mapStateToProps) {
  return class Container extends Component {
    render() {
      const { state } = this.context.store.getState();

      const props = mapStateToProps(state);

      return <ChildComponentClass {...this.props} {...props} />;
    }
  }
}

This question has already been answered, but I believe it would be good to throw some useful methods not previously discussed into the mix, and compare all methods proposed thus far in terms of performance.

Here are some useful solutions to this problem, in increasing order of performance.

DataFrame.agg

This is a simple str.format-based approach.

df['baz'] = df.agg('{0[bar]} is {0[foo]}'.format, axis=1)
df
  foo  bar     baz
0   a    1  1 is a
1   b    2  2 is b
2   c    3  3 is c

You can also use f-string formatting here:

df['baz'] = df.agg(lambda x: f"{x['bar']} is {x['foo']}", axis=1)
df
  foo  bar     baz
0   a    1  1 is a
1   b    2  2 is b
2   c    3  3 is c

char.array-based Concatenation

Convert the columns to concatenate as chararrays, then add them together.

a = np.char.array(df['bar'].values)
b = np.char.array(df['foo'].values)

df['baz'] = (a + b' is ' + b).astype(str)
df
  foo  bar     baz
0   a    1  1 is a
1   b    2  2 is b
2   c    3  3 is c

List Comprehension with zip

I cannot overstate how underrated list comprehensions are in pandas.

df['baz'] = [str(x) + ' is ' + y for x, y in zip(df['bar'], df['foo'])]

Alternatively, using str.join to concat (will also scale better):

df['baz'] = [
    ' '.join([str(x), 'is', y]) for x, y in zip(df['bar'], df['foo'])]

df
  foo  bar     baz
0   a    1  1 is a
1   b    2  2 is b
2   c    3  3 is c

List comprehensions excel in string manipulation, because string operations are inherently hard to vectorize, and most pandas "vectorised" functions are basically wrappers around loops. I have written extensively about this topic in For loops with pandas - When should I care?. In general, if you don't have to worry about index alignment, use a list comprehension when dealing with string and regex operations.

The list comp above by default does not handle NaNs. However, you could always write a function wrapping a try-except if you needed to handle it.

def try_concat(x, y):
    try:
        return str(x) + ' is ' + y
    except (ValueError, TypeError):
        return np.nan


df['baz'] = [try_concat(x, y) for x, y in zip(df['bar'], df['foo'])]

In my case, I was using MySQL WorkBench and

ALTER TABLE table_name RENAME COLUMN old_name new_name varchar(50) not null; 
// without TO and specify data type of that column 

was enough to change the column name!

1. Go to Project structure (Ctrl + Alt + shift + S) -> Platforn settings -> SDKs -> press "Plus" icon
2. Select "Android SDK" and input the SDKs path (for exanple: C:\Program Files (x86)\Android\android-sdk)
3. Apply or OK button
4. Be happy

If you are a linux user:

To show the engines for all tables for all databases on a mysql server, without tables information_schema, mysql, performance_schema:

less < <({ for i in $(mysql -e "show databases;" | cat | grep -v -e Database-e information_schema -e mysql -e performance_schema); do echo "--------------------$i--------------------";  mysql -e "use $i; show table status;"; done } | column -t)

You might love this, if you are on linux, at least.

Will open all info for all tables in less, press -S to chop overly long lines.

I am using intellij CE to create the WAR, and deploying the war externally using tomcat deployment manager. This works for testing the application however I still couldnt find the way to debug it.

1. open cmd and current dir to tomcat/bin.
2. you can start and stop the server using the batch files start.bat and shutdown.bat.
3. Now build your app using mvn goal in intellij.
4. Open localhost:8080/ **Your port number may differ.
5. Use this tomcat application to deploy the application, If you get the authentication error, you would need to set the credentials under conf/tomcat-users.xml.

If you just want to change where the iframe points to and not the actual content inside the iframe, you would just need to change the src attribute.

 $("#myiframe").attr("src", "newwebpage.html");

        try {
            out = new FileOutputStream("M:\\test2.xml");
        } catch (FileNotFoundException ex) {
            System.out.println("File not found. ");
        }

        byte[] bytes = new byte[16*1024];

        int count;
        while ((count = in.read(bytes)) > 0) {
            out.write(bytes, 0, count);
        }

        out.close();
        in.close();
        socket.close();
        serverSocket.close();
    }
}

and the Client:

public class Client {
    public static void main(String[] args) throws IOException {
        Socket socket = null;
        String host = "127.0.0.1";

        socket = new Socket(host, 4444);
        
        File file = new File("M:\\test.xml");
        // Get the size of the file
        long length = file.length();
        byte[] bytes = new byte[16 * 1024];
        InputStream in = new FileInputStream(file);
        OutputStream out = socket.getOutputStream();
        
        int count;
        while ((count = in.read(bytes)) > 0) {
            out.write(bytes, 0, count);
        }

        out.close();
        in.close();
        socket.close();
    }
}

Try this:

import sys

print sys.stdin.read().upper()

and check it with:

$ echo "Hello World" | python myFile.py

If you have misused <input type="date" /> you can probably use:

$('input[type="date"]').attr('type','text');

after they have loaded to turn them into text inputs. You'll need to attach your custom datepicker first:

$('input[type="date"]').datepicker().attr('type','text');

Or you could give them a class:

$('input[type="date"]').addClass('date').attr('type','text');

There's also a cute little trick that lets you specify a single host on the command line (or multiple hosts, I guess), without an intermediary inventory:

ansible-playbook -i "imac1-local," user.yml

Note the comma (,) at the end; this signals that it's a list, not a file.

Now, this won't protect you if you accidentally pass a real inventory file in, so it may not be a good solution to this specific problem. But it's a handy trick to know!

Setting isBodyHtml to true allows you to use HTML tags in the message body:

msg = new MailMessage("[email protected]",
                "[email protected]", "Message from PSSP System",
                "This email sent by the PSSP system<br />" +
                "<b>this is bold text!</b>");

msg.IsBodyHtml = true;

In your view, you have to cast it back to the original type. Without the cast, it's just an object.

<td>@((ViewBag.data as ICollection<Person>).First().FirstName)</td>

ViewBag is a C# 4 dynamic type. Entities returned from it are also dynamic unless cast. However, extension methods like .First() and all the other Linq ones do not work with dynamics.

Edit - to address the comment:

If you want to display the whole list, it's as simple as this:

<ul>
    @foreach (var person in ViewBag.data)
    {
        <li>@person.FirstName</li>
    }
</ul>

Extension methods like .First() won't work, but this will.

For currency, I'd suggest:

<div><label>Amount $
    <input type="number" placeholder="0.00" required name="price" min="0" value="0" step="0.01" title="Currency" pattern="^\d+(?:\.\d{1,2})?$" onblur="
this.parentNode.parentNode.style.backgroundColor=/^\d+(?:\.\d{1,2})?$/.test(this.value)?'inherit':'red'
"></label></div>

See http://jsfiddle.net/vx3axsk5/1/

The HTML5 properties "step", "min" and "pattern" will be validated when the form is submit, not onblur. You don't need the step if you have a pattern and you don't need a pattern if you have a step. So you could revert back to step="any" with my code since the pattern will validate it anyways.

If you'd like to validate onblur, I believe giving the user a visual cue is also helpful like coloring the background red. If the user's browser doesn't support type="number" it will fallback to type="text". If the user's browser doesn't support the HTML5 pattern validation, my JavaScript snippet doesn't prevent the form from submitting, but it gives a visual cue. So for people with poor HTML5 support, and people trying to hack into the database with JavaScript disabled or forging HTTP Requests, you need to validate on the server again anyways. The point with validation on the front-end is for a better user experience. So as long as most of your users have a good experience, it's fine to rely on HTML5 features provided the code will still works and you can validate on the back-end.

Building off the accepted answer by @dennisg, I accomplished this successfully using jQuery.XDomainRequest.js by MoonScript.

The following code worked correctly in Chrome, Firefox and IE10, but failed in IE9. I simply included the script and it now automagically works in IE9. (And probably 8, but I haven't tested it.)

var displayTweets = function () {
    $.ajax({
        cache: false,
        type: 'GET',
        crossDomain: true,
        url: Site.config().apiRoot + '/Api/GetTwitterFeed',
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        success: function (data) {
            for (var tweet in data) {
                displayTweet(data[tweet]);
            }
        }
    });
};

It is simple, as a java, Android also supporting singleton. -

Singleton is a part of Gang of Four design pattern and it is categorized under creational design patterns.

-> Static member : This contains the instance of the singleton class.

-> Private constructor : This will prevent anybody else to instantiate the Singleton class.

-> Static public method : This provides the global point of access to the Singleton object and returns the instance to the client calling class.

1. create private instance
2. create private constructor

3. use getInstance() of Singleton class

   public class Logger{
   private static Logger   objLogger;
   private Logger(){
   
           //ToDo here
   
   }
   public static Logger getInstance()
   {
       if (objLogger == null)
      {
         objLogger = new Logger();
      }
      return objLogger;
      }
   
   }
   

while use singleton -

Logger.getInstance();

Usually a null pointer (which can be of any type, including a void pointer !) points to:

• the address 0, against which most CPU instructions sets can do a very fast compare-and-branch (to check for uninitialized or invalid pointers, for instance) with optimal code size/performance for the ISA.

• an address that's illegal for user code to access (such as 0x00000000 in many cases), so that if a code actually tries to access data at or near this address, the OS or debugger can easily stop or trap a program with this bug.

A void pointer is usually a method of cheating or turning-off compiler type checking, for instance if you want to return a pointer to one type, or an unknown type, to use as another type. For instance malloc() returns a void pointer to a type-less chunk of memory, the type of which you can cast to later use as a pointer to bytes, short ints, double floats, typePotato's, or whatever.

Spy can be useful when you want to create unit tests for legacy code.

I have created a runable example here https://www.surasint.com/mockito-with-spy/ , I copy some of it here.

If you have something like this code:

public void transfer(  DepositMoneyService depositMoneyService, WithdrawMoneyService withdrawMoneyService, 
             double amount, String fromAccount, String toAccount){
    withdrawMoneyService.withdraw(fromAccount,amount);
    depositMoneyService.deposit(toAccount,amount);
}

You may don't need spy because you can just mock DepositMoneyService and WithdrawMoneyService.

But with some, legacy code, dependency is in the code like this:

    public void transfer(String fromAccount, String toAccount, double amount){

        this.depositeMoneyService = new DepositMoneyService();
        this.withdrawMoneyService = new WithdrawMoneyService();

        withdrawMoneyService.withdraw(fromAccount,amount);
        depositeMoneyService.deposit(toAccount,amount);
    }

Yes, you can change to the first code but then API is changed. If this method is being used by many places, you have to change all of them.

Alternative is that you can extract the dependency out like this:

    public void transfer(String fromAccount, String toAccount, double amount){
        this.depositeMoneyService = proxyDepositMoneyServiceCreator();
        this.withdrawMoneyService = proxyWithdrawMoneyServiceCreator();

        withdrawMoneyService.withdraw(fromAccount,amount);
        depositeMoneyService.deposit(toAccount,amount);
    }
    DepositMoneyService proxyDepositMoneyServiceCreator() {
        return new DepositMoneyService();
    }

    WithdrawMoneyService proxyWithdrawMoneyServiceCreator() {
        return new WithdrawMoneyService();
    }

Then you can use the spy the inject the dependency like this:

DepositMoneyService mockDepositMoneyService = mock(DepositMoneyService.class);
        WithdrawMoneyService mockWithdrawMoneyService = mock(WithdrawMoneyService.class);

    TransferMoneyService target = spy(new TransferMoneyService());

    doReturn(mockDepositMoneyService)
            .when(target).proxyDepositMoneyServiceCreator();

    doReturn(mockWithdrawMoneyService)
            .when(target).proxyWithdrawMoneyServiceCreator();

As to how to cope with the path size limitation on Windows - using 7zip to pack (and unpack) your path-length sensitive files seems like a viable workaround. I've used it to transport several IDE installations (those Eclipse plugin paths, yikes!) and piles of autogenerated documentation and haven't had a single problem so far.

Not really sure how it evades the 260 char limit set by Windows (from a technical PoV), but hey, it works!

More details on their SourceForge page here:

"NTFS can actually support pathnames up to 32,000 characters in length."

7-zip also support such long names.

But it's disabled in SFX code. Some users don't like long paths, since they don't understand how to work with them. That is why I have disabled it in SFX code.

and release notes:

9.32 alpha 2013-12-01

• Improved support for file pathnames longer than 260 characters.

4.44 beta 2007-01-20

• 7-Zip now supports file pathnames longer than 260 characters.

IMPORTANT NOTE: For this to work properly, you'll need to specify the destination path in the 7zip "Extract" dialog directly, rather than dragging & dropping the files into the intended folder. Otherwise the "Temp" folder will be used as an interim cache and you'll bounce into the same 260 char limitation once Windows Explorer starts moving the files to their "final resting place". See the replies to this question for more information.

px to dp:

int valueInpx = ...;
int valueInDp= (int) TypedValue.applyDimension(
            TypedValue.COMPLEX_UNIT_DIP, valueInpx , getResources()
                .getDisplayMetrics());

Actually, the submit button already performs this function.

Try in the FORM:

<form method="post">
<input type="submit" name="treasure" value="go!">
</form>

Then in the PHP handler:

if (isset($_POST['treasure'])){
echo "treasure will be set if the form has been submitted (to TRUE, I believe)";
}

I don't like very much iterator's semantic, please consider this as an option. It's also safer as you publish less of your internal state

private Map<String, String> JSONtoMAP(String jsonString) {

    JSONObject json = new JSONObject(jsonString);
    Map<String, String> outMap = new HashMap<String, String>();

    for (String curKey : (Set<String>) json.keySet()) {
        outMap.put(curKey, json.getString(curKey));
    }

    return outMap;

}

You can also try WANem which is an open source Wide Area Network emulator. You can download the image (ISO, Knoppix live CD) or VMWare virtual appliances.

There are 3 problems.

1) Incorrect decimal separator

Different cultures use different decimal separators (namely , and .).

If you replace . with , it should work as expected:

Console.WriteLine(Convert.ToDouble("52,8725945"));

You can parse your doubles using overloaded method which takes culture as a second parameter. In this case you can use InvariantCulture (What is the invariant culture) e.g. using double.Parse:

double.Parse("52.8725945", System.Globalization.CultureInfo.InvariantCulture);

You should also take a look at double.TryParse, you can use it with many options and it is especially useful to check wheter or not your string is a valid double.

2) You have an incorrect double

One of your values is incorrect, because it contains two dots:

15.5859949000000662452.23862099999999

3) Your array has an empty value at the end, which is an incorrect double

You can use overloaded Split which removes empty values:

string[] someArray = a.Split(new char[] { '#' }, StringSplitOptions.RemoveEmptyEntries);

Bootstrap3 users try the given below code. It worked for me.

function close_toggle() {
   if ($(window).width() <= 768) {
      $('.nav a').on('click', function(){
          $(".navbar-toggle").click();
      });
   }
   else {
     $('.nav a').off('click');
   }
}
close_toggle();

$(window).resize(close_toggle);

The 2020 answer: it probably doesn't matter

The best answer here was from 2012, so I decided to test for myself. On Chrome for Android, the JS and CSS resources are downloaded in parallel and I could not detect a difference in page rendering speed.

I included a more detailed writeup on my blog

In fact, most compilers emit the same code for both functions calls, because references are generally implemented using pointers.

Following this logic, when an argument of (non-const) reference type is used in the function body, the generated code will just silently operate on the address of the argument and it will dereference it. In addition, when a call to such a function is encountered, the compiler will generate code that passes the address of the arguments instead of copying their value.

Basically, references and pointers are not very different from an implementation point of view, the main (and very important) difference is in the philosophy: a reference is the object itself, just with a different name.

References have a couple more advantages compared to pointers (e. g. they can't be NULL, so they are safer to use). Consequently, if you can use C++, then passing by reference is generally considered more elegant and it should be preferred. However, in C, there's no passing by reference, so if you want to write C code (or, horribile dictu, code that compiles with both a C and a C++ compiler, albeit that's not a good idea), you'll have to restrict yourself to using pointers.

 set host=%COMPUTERNAME%
 echo %host%

This one enough. no need of extra loops of big coding.

Just set the background of the canvas to transparent.

#canvasID{
    background:transparent;
}

It's important to note, that NULL doesn't equal NULL.

NULL is not a value, and therefore cannot be compared to another value.

where x is null checks whether x is a null value.

where x = null is checking whether x equals NULL, which will never be true

Suppose you are running a test python file named request.py In request.py, you write

import request

so this also most likely a circular import.

Solution:

Just change your test file to another name such as aaa.py, other than request.py.

Do not use names that are already used by other libs.

If your current line wraps around the visible screen onto the next line, you can use g$ to get to the end of the screen line.

While waiting for a reply for ideas here, I had decided to try something. I ran regedit as administrator, navigated to the HKEY_CLASSES_ROOT\TypeLib Key and then did a search for "MSCOMCTL.OCX"... I deleted EVERY key that referenced this .ocx file.

After searching the entire registry, deleting what I found, I ran command prompt as administrator. I then navigated to C:\Windows\SysWOW64 and typed the following commands:

regsvr32 MSCOMCTL.OCX
regtlib msdatsrc.tlb

Upon registering these two files again, everything is WORKING! I scoured the web for HOURS looking for this solution to no avail. It just so happens I fixed it myself after posting a question here :( Even though Visual Studio 6 is outdated, hopefully this may still help others!

This could be for 2 reasons for this:

1. service ref is outdated, right click service ref n update it.

2. contract which you have implemented might be different what client has. Compare both service n client contract n fix the contracts mismatch.

You could use substr, I guess:

$string2 = substr($string1, 0, 100);

or mb_substr for multi-byte strings:

$string2 = mb_substr($string1, 0, 100);

You could create a function wich uses this function and appends for instance '...' to indicate that it was shortened. (I guess there's allready a hundred similar replies when this is posted...)

Python version is not supported Uninstall python

https://www.python.org/downloads/release/python-362/

You should check and use the exact version in install page. https://www.tensorflow.org/install/install_windows

python 3.6.2 or python 3.5.2 solved this issue for me

If you don't want your read to be broken by newline character, use -

#!/bin/bash
while IFS='' read -r line || [[ -n "$line" ]]; do
    echo "$line"
done < "$1"

Then run the script with file name as parameter.

As the file handlers points to i-nodes (which are stored independently from file names) on Linux/Unix systems You can rename the default nohup.out to any other filename any time after starting nohup something&. So also one could do the following:

$ nohup something&
$ mv nohup.out nohup2.out
$ nohup something2&

Now something adds lines to nohup2.out and something2 to nohup.out.

None of these answers worked for me. I just by-passed the problem. I did this:

$('#tabs-tab1').removeClass('tabs-hide');
$('#tabs-tab2').addClass('tabs-hide');
$('#container-tabs a[href="#tabs-tab2"]').parent().removeClass('tabs-selected');
$('#container-tabs a[href="#tabs-tab1"]').parent().addClass('tabs-selected');

It works great.

Span is an inline element. It has no width or height.

You could turn it into a block-level element, then it will accept your dimension directives.

span.product__specfield_8_arrow
{
    display: inline-block; /* or block */
}

Firstly, understand that DateTime objects aren't formatted. They just store the Year, Month, Day, Hour, Minute, Second, etc as a numeric value and the formatting occurs when you want to represent it as a string somehow. You can compare DateTime objects without formatting them.

To compare an input date with DateTime.Now, you need to first parse the input into a date and then compare just the Year/Month/Day portions:

DateTime inputDate;
if(!DateTime.TryParse(inputString, out inputDate))
    throw new ArgumentException("Input string not in the correct format.");

if(inputDate.Date == DateTime.Now.Date) {
    // Same date!
}

Going by the comments as well as personal experience, I say no, there is no need for range(len(a)). Everything you can do with range(len(a)) can be done in another (usually far more efficient) way.

You gave many examples in your post, so I won't repeat them here. Instead, I will give an example for those who say "What if I want just the length of a, not the items?". This is one of the only times you might consider using range(len(a)). However, even this can be done like so:

>>> a = [1, 2, 3, 4]
>>> for _ in a:
...     print True
...
True
True
True
True
>>>

Clements answer (as shown by Allik) can also be reworked to remove range(len(a)):

>>> a = [6, 3, 1, 2, 5, 4]
>>> sorted(range(len(a)), key=a.__getitem__)
[2, 3, 1, 5, 4, 0]
>>> # Note however that, in this case, range(len(a)) is more efficient.
>>> [x for x, _ in sorted(enumerate(a), key=lambda i: i[1])]
[2, 3, 1, 5, 4, 0]
>>>

So, in conclusion, range(len(a)) is not needed. Its only upside is readability (its intention is clear). But that is just preference and code style.

Both of these should work:

$("#captureImage").prop('checked', false);

AND/OR

$("#captureImage").removeAttr('checked');

... you can try both together.

The increasingly popular D3 library handles the oddities of appending/manipulating svg very nicely. You may want to consider using it as opposed to the jQuery hacks mentioned here.

HTML

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

Javascript

var circle = d3.select("svg").append("circle")
    .attr("r", "10")
    .attr("style", "fill:white;stroke:black;stroke-width:5");

Clean and simple:

awk '{print $2}' file.txt | paste -s -d, -

There's this Explorer Exclude extension that exactly does this. https://marketplace.visualstudio.com/items?itemName=RedVanWorkshop.explorer-exclude-vscode-extension

It adds an option to hide current folder/file to the right click menu. It also adds a vertical tab Hidden Items to explorer menu where you can see currently hidden files & folders and can toggle them easily.

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")
}());

window.open doesn't work across all browsers, Google it and you will find a way of detecting the correct dialog type.

Also, move the onclick call to the input button for it to only fire when the user submits.

There are two differences between static inner and non static inner classes.

1. In case of declaring member fields and methods, non static inner class cannot have static fields and methods. But, in case of static inner class, can have static and non static fields and method.

2. The instance of non static inner class is created with the reference of object of outer class, in which it has defined, this means it has enclosing instance. But the instance of static inner class is created without the reference of Outer class, which means it does not have enclosing instance.

See this example

class A
{
    class B
    {
        // static int x; not allowed here
    }

    static class C
    {
        static int x; // allowed here
    }
}

class Test
{
    public static void main(String… str)
    {
        A a = new A();

        // Non-Static Inner Class
        // Requires enclosing instance
        A.B obj1 = a.new B(); 

        // Static Inner Class
        // No need for reference of object to the outer class
        A.C obj2 = new A.C(); 
    }
}

I was in a weird situation in VS2019 where choosing View -> Report Data did nothing, and pressing Ctrl-Alt-D did nothing. The Report Data window had just strangely appeared on the left for no reason, when it was supposed to be on the right, and so I had moved it back to the right and then made it auto-hide. Not long after that it disappeared and would refuse to reappear. Possibly it was off-screen but hard to say.

To fix, I had to resort to using Window -> Reset Window Layout which restored its position and I was able to use it again.

When I use a password in base64, I put the separator ":" because the base64 string may has "=". For example (I use ksh):

> echo "Abc123" | base64
QWJjMTIzCg==

In parameters.ini put the line pass:QWJjMTIzCg==, and finally:

> PASS=`awk -F":" '/pass/ {print $2 }' parameters.ini | base64 --decode`
> echo "$PASS"
Abc123

If the line has spaces like "pass : QWJjMTIzCg== " add | tr -d ' ' to trim them:

> PASS=`awk -F":" '/pass/ {print $2 }' parameters.ini | tr -d ' ' | base64 --decode`
> echo "[$PASS]"
[Abc123]

The dot character means match any character, so .* means zero or more occurrences of any character. You probably mean to use .* rather than just *.

you can use the simpleDateFormat to parse the string date.

If you want to use enhanced loop, you can convert the string to charArray

for (char ch : exampleString.toCharArray()) {
  System.out.println(ch);
}

To run function onLoad

jQuery(window).on("load", function(){
    ..code..
});

To run code onDOMContentLoaded (also called onready)

jQuery(document).ready(function(){
    ..code..
});

or the recommended shorthand for onready

jQuery(function($){
    ..code.. ($ is the jQuery object)
});

onready fires when the document has loaded

onload fires when the document and all the associated content, like the images on the page have loaded.

$("#foo > div").length

jQuery has a .size() function which will return the number of times that an element appears but, as specified in the jQuery documentation, it is slower and returns the same value as the .length property so it is best to simply use the .length property. From here: http://www.electrictoolbox.com/get-total-number-matched-elements-jquery/

Run below commands from app's home directory:

1. rake db:migrate:down VERSION="20140311142212" (here version is the timestamp prepended by rails when migration was created. This action will revert DB changes due to this migration)

2. Run "rails destroy migration migration_name" (migration_name is the one use chose while creating migration. Remove "timestamp_" from your migration file name to get it)

For OS X Yosemite and above, and Xcode 6+

Open Xcode > Window > Devices

Choose your device. You can see the installed application list and add a new one by hitting +

If you don't want to lose the columns you shift past the end of your dataframe, simply append the required number first:

    offset = 5
    DF = DF.append([np.nan for x in range(offset)])
    DF = DF.shift(periods=offset)
    DF = DF.reset_index() #Only works if sequential index

You can simply use DataColumnCollection.IndexOf

So that you can get the index of the required column by name then use it with your row:

row[dt.Columns.IndexOf("ColumnName")] = columnValue;

I had to do this for a project. What I ended up doing was start a separate thread for the function

t = threading.Thread(target =heartbeat, args=(worker,))
t.start()

****heartbeat is my function, worker is one of my arguments****

inside of my heartbeat function:

def heartbeat(worker):

    while True:
        time.sleep(5)
        #all of my code

So when I start the thread the function will repeatedly wait 5 seconds, run all of my code, and do that indefinitely. If you want to kill the process just kill the thread.

Open your PHPMyAdmin, don't select any database and look for Binary Log tab . You can select different logs from a drop down list and press GO Button to view them.

Detach is unnecessary.

The answer (as of 2013) is simple:

$('#parentNode').append($('#childNode'));

According to http://api.jquery.com/append/

You can also select an element on the page and insert it into another:

$('.container').append($('h2'));

If an element selected this way is inserted into a single location elsewhere in the DOM, it will be moved into the target (not cloned).

In MySQL TRUE and FALSE are synonyms for TINYINT(1).

So therefore its basically the same thing, but MySQL is converting to 0/1 - so just use a TINYINT if that's easier for you

P.S.
The performance is likely to be so minuscule (if at all), that if you need to ask on StackOverflow, then it won't affect your database :)

While there are two excellent answers telling you how to do it, I feel that another answer is missing: In most cases you shouldn't do it at all.

Arrays are cumbersome, in most cases you are better off using the Collection API.

With Collections, you can add and remove elements and there are specialized Collections for different functionality (index-based lookup, sorting, uniqueness, FIFO-access, concurrency etc.).

While it's of course good and important to know about Arrays and their usage, in most cases using Collections makes APIs a lot more manageable (which is why new libraries like Google Guava hardly use Arrays at all).

So, for your scenario, I'd prefer a List of Lists, and I'd create it using Guava:

List<List<String>> listOfLists = Lists.newArrayList();
listOfLists.add(Lists.newArrayList("abc","def","ghi"));
listOfLists.add(Lists.newArrayList("jkl","mno","pqr"));

It is possible to do with CSS only by selecting active and focus pseudo element of the button.

button:active{
    background:olive;
}

button:focus{
    background:olive;
}

See codepen: http://codepen.io/fennefoss/pen/Bpqdqx

You could also write a simple jQuery click function which changes the background color.

HTML:

<button class="js-click">Click me!</button>

CSS:

button {
  background: none;
}

JavaScript:

  $( ".js-click" ).click(function() {
    $( ".js-click" ).css('background', 'green');
  });

Check out this codepen: http://codepen.io/fennefoss/pen/pRxrVG

It is called as String Interpolation. It is way of creating NEW string with CONSTANTS, VARIABLE, LITERALS and EXPRESSIONS. for examples:

      let price = 3
      let staringValue = "The price of \(price) mangoes is equal to \(price*price) "

also

let string1 = "anil"
let string2 = "gupta"
let fullName = string1 + string2  // fullName is equal to "anilgupta"
or 
let fullName = "\(string1)\(string2)" // fullName is equal to "anilgupta"

it also mean as concatenating string values.

Hope this helps you.

For fontawesome 5.x+ the most simplest way would be the following,

install using npm package: npm install --save @fortawesome/fontawesome-free

In your styles.scss file include:

$fa-font-path: "~@fortawesome/fontawesome-free/webfonts";
@import '~@fortawesome/fontawesome-free/scss/fontawesome';
@import '~@fortawesome/fontawesome-free/scss/solid';
@import '~@fortawesome/fontawesome-free/scss/regular';

Note: if you have _variables.scss file then it's more appropriate to include the $fa-font-path inside it and not in styles.scss file.

You can also do this...

my_string = "Hello world"

if my_string["Hello"]
  puts 'It has "Hello"'
else
  puts 'No "Hello" found'
end

# => 'It has "Hello"'

This example uses Ruby's String #[] method.

I would use the numpy library, which would allow you to do this for a list of numbers as well:

from numpy import array
a = array([1, 2, 3, 4, 5, 6,])
a[a < 2]

The main difference between name() and toString() is that name() is a final method, so it cannot be overridden. The toString() method returns the same value that name() does by default, but toString() can be overridden by subclasses of Enum.

Therefore, if you need the name of the field itself, use name(). If you need a string representation of the value of the field, use toString().

For instance:

public enum WeekDay {
    MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY;

    public String toString() {
        return name().charAt(0) + name().substring(1).toLowerCase();
    }
}

In this example, WeekDay.MONDAY.name() returns "MONDAY", and WeekDay.MONDAY.toString() returns "Monday".

WeekDay.valueOf(WeekDay.MONDAY.name()) returns WeekDay.MONDAY, but WeekDay.valueOf(WeekDay.MONDAY.toString()) throws an IllegalArgumentException.

This should work, at least according to the Search Filter Syntax article on MSDN network.

The "hang-up" you have noticed is probably just a delay. Try running the same query with narrower scope (for example the specific OU where the test object is located), as it may take very long time for processing if you run it against all AD objects.

You may also try separating the filter into two parts:

(|(displayName=*searchstring)(displayName=searchstring*))

If I understand the situation correctly, you are just passing json data through the http body, instead of application/x-www-form-urlencoded data.

You can fetch this data with this snippet:

$request_body = file_get_contents('php://input');

If you are passing json, then you can do:

$data = json_decode($request_body);

$data then contains the json data is php array.

php://input is a so called wrapper.

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".

pip3 install mysql-connector-python did solve my problem as well. Ignore using mysql-connector module.

Why not simply use angular.isObject with negation? e.g.

if (!angular.isObject(obj)) {
    return;
}

Simply put:

SELECT * 
FROM TABLE_NAME
WHERE
dob > '1/21/2012'

Where 1/21/2012 is the date and you want all data, including that date.

SELECT * 
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'

Use a between if you're selecting time between two dates

A traditional application architecture is:

• A user interface
• Undefined stuff (implementation) that's encapsulated/hidden behind the user interface

If you want to access the data programmatically, you might need to resort to screen-scraping.

SOA seems to me to be an architecture which focus on exposing machine-readable data and/or APIs, instead of on exposing UIs.

This should do what you want:

<div class="comeBack_up" *ngIf="(previous_info | json) != ({} | json)">

or shorter

<div class="comeBack_up" *ngIf="(previous_info | json) != '{}'">

Each {} creates a new instance and ==== comparison of different objects instances always results in false. When they are convert to strings === results to true

Plunker example

Alternative: Stream.concat()

Stream.concat(map.values().stream(), listContainer.lst.stream())
                             .collect(Collectors.toList()

I think Ctrl + Alt + O works when the import is unused but a valid import. However, say you try to import a class from a package that does not exist or no longer exists (which can happen during refactoring), the shortcut command does not work (atleast it didn't for me). If you have more than one file like this, things can get problematic.

To solve this problem, click on Analyse -> Inspect code -> (select your module / project). Let it perform the analysis. Go down to Imports -> Unused imports. Click on the "Delete unnecessary import" button that appears on the right.

I put this in my makefile, right the next line after adb install ...

adb shell monkey -p `cat .identifier` -c android.intent.category.LAUNCHER 1

For this to work there must be a .identifier file with the app's bundle identifier in it, like com.company.ourfirstapp

No need to hunt activity name.

Use the CSS property border on the <td>s following the <tr>s you do not want to have the border.

In my example I made a class noBorder that I gave to one <tr>. Then I use a simple selector tr.noBorder td to make the border go away for all the <td>s that are inside of <tr>s with the noBorder class by assigning border: 0.

Note that you do not need to provide the unit (i.e. px) if you set something to 0 as it does not matter anyway. Zero is just zero.

table, tr, td {_x000D_
  border: 3px solid red;_x000D_
}_x000D_
tr.noBorder td {_x000D_
  border: 0;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>A1</td>_x000D_
    <td>B1</td>_x000D_
    <td>C1</td>_x000D_
  </tr>_x000D_
  <tr class="noBorder">_x000D_
    <td>A2</td>_x000D_
    <td>B2</td>_x000D_
    <td>C2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>A3</td>_x000D_
    <td>A3</td>_x000D_
    <td>A3</td>_x000D_
  </tr>_x000D_
</table>

Here's the output as an image:

To add to craig_h's comment above (I currently don't have enough rep to add this as a comment to his answer, sorry), if your primary key is not an integer, you'll also want to tell your model what data type it is, by setting keyType at the top of the model definition.

public $keyType = 'string'

Eloquent understands any of the types defined in the castAttribute() function, which as of Laravel 5.4 are: int, float, string, bool, object, array, collection, date and timestamp.

This will ensure that your primary key is correctly cast into the equivalent PHP data type.

Copy a file from one location to another location means,need to copy the whole content to another location.Files.copy(Path source, Path target, CopyOption... options) throws IOException this method expects source location which is original file location and target location which is a new folder location with destination same type file(as original). Either Target location needs to exist in our system otherwise we need to create a folder location and then in that folder location we need to create a file with the same name as original filename.Then using copy function we can easily copy a file from one location to other.

 public static void main(String[] args) throws IOException {
                String destFolderPath = "D:/TestFile/abc";
                String fileName = "pqr.xlsx";
                String sourceFilePath= "D:/TestFile/xyz.xlsx";
                File f = new File(destFolderPath);
                if(f.mkdir()){
                    System.out.println("Directory created!!!!");
                }
                else {
                    System.out.println("Directory Exists!!!!");
                }
                f= new File(destFolderPath,fileName);
                if(f.createNewFile())   {

                    System.out.println("File Created!!!!");
                }   else {
                    System.out.println("File exists!!!!");
                }

                Files.copy(Paths.get(sourceFilePath), Paths.get(destFolderPath, fileName),REPLACE_EXISTING);
                System.out.println("Copy done!!!!!!!!!!!!!!");


            }

As pointed out by @ezain reload controllers only when its necessary. Another cleaner way of updating data when changing states rather than reloading the controller is using broadcast events and listening to such events in controllers that need to update data on views.

Example: in your login/logout functions you can do something like so:

$scope.login = function(){
    //After login logic then send a broadcast
    $rootScope.$broadcast("user-logged-in");
    $state.go("mainPage");
};
$scope.logout = function(){
   //After logout logic then send a broadcast
   $rootScope.$broadcast("user-logged-out");
   $state.go("mainPage");
};

Now in your mainPage controller trigger the changes in the view by using the $on function to listen to broadcast within the mainPage Controller like so:

$scope.$on("user-logged-in", function(){
     //update mainPage view data here eg. $scope.username = 'John';
});

$scope.$on("user-logged-out", function(){
    //update mainPage view data here eg. $scope.username = '';
});

I believe this is much simpler;

dynamic obj = JObject.Parse(jsonString);
string results  = obj.results;
foreach(string result in result.Split('))
{
//Todo
}

By reading your exception , It's sure that you forgot to autowire customerService

You should autowire your customerservice .

make following changes in your controller class

@Controller
public class CustomerController{

    @Autowired
    private Customerservice customerservice;
......other code......

}

Again your service implementation class

write

@Service
public class CustomerServiceImpl implements CustomerService {
    @Autowired
    private CustomerDAO customerDAO;
......other code......

.....add transactional methods
}

If you are using hibernate make necessary changes in your applicationcontext xml file(configuration of session factory is needed).

you should autowire sessionFactory set method in your DAO mplementation

i was looking for gcd and lcm of array elements and found a good solution in the following link.

https://www.hackerrank.com/challenges/between-two-sets/forum

which includes following code. The algorithm for gcd uses The Euclidean Algorithm explained well in the link below.

https://www.khanacademy.org/computing/computer-science/cryptography/modarithmetic/a/the-euclidean-algorithm

private static int gcd(int a, int b) {
    while (b > 0) {
        int temp = b;
        b = a % b; // % is remainder
        a = temp;
    }
    return a;
}

private static int gcd(int[] input) {
    int result = input[0];
    for (int i = 1; i < input.length; i++) {
        result = gcd(result, input[i]);
    }
    return result;
}

private static int lcm(int a, int b) {
    return a * (b / gcd(a, b));
}

private static int lcm(int[] input) {
    int result = input[0];
    for (int i = 1; i < input.length; i++) {
        result = lcm(result, input[i]);

    return result;

My problem was that the file I was referencing from inside my home.html was a .j2 instead of a .html, and when I changed it back jinja could read it.

Stupid error but it might help someone.

execute with in under api level 19 right click on project go to preporty and then select android

<uses-sdk

    android:targetSdkVersion="19" />

Why would the first way not work. Canvas object is created and the size is set and the grahpics are set. I always find this strange. Also if a class extends JComponent you can override the

paintComponent(){
  super...
}

and then shouldn't you be able to create and instance of the class inside of another class and then just call NewlycreateinstanceOfAnyClass.repaint();

I have tried this approach for some game programming I have been working and it doesn't seem to work the way I think that it should be.

Assuming your byteData array is biger than 32 + byteSalt.length()...you're going to it's length, not byteSalt.length. You're trying to copy from beyond the array end.

if not %1 == "" (

must be

if not "%1" == "" (

If an argument isn't given, it's completely empty, not even "" (which represents an empty string in most programming languages). So we use the surrounding quotes to detect an empty argument.

I came across a similar issue. However this issue was caused because of the way i designed the pages to bring the requests in. I placed all of my .js files as the last thing to be applied to the page, therefore they are at the end of my document. The .js files have all my functions include. The script manager seems that to be able to call this function it needs the js file already present with the function being called at the time of load. Hope this helps anyone else.

check your $PATH

tox has a command line mode:

audrey:tests jluc$ pip list | grep tox
tox (2.3.1)

where is it?

(edit: the 2.7 stuff doesn't matter much here, sub in any 3.x and pip's behaving pretty much the same way)

audrey:tests jluc$ which tox
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/tox

and what's in my $PATH?

audrey:tests jluc$ echo $PATH
/opt/chefdk/bin:/opt/chefdk/embedded/bin:/opt/local/bin:..../opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin...

Notice the /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin? That's what allows finding my pip-installed stuff

Now, to see where things are from Python, try doing this (substitute rosdep for tox).

$python
>>> import tox
>>> tox.__file__

that prints out:

Now, cd to the directory right above lib in the above. Do you see a bin directory? Do you see rosdep in that bin? If so try adding the bin to your $PATH.

audrey:2.7 jluc$ cd /opt/local/Library/Frameworks/Python.framework/Versions/2.7
audrey:2.7 jluc$ ls -1

Building on @Mike Gledhill's code, I've taken it a step further and added more parameters. If you have a SVG RECT and want text to wrap inside it, this may be handy:

function wraptorect(textnode, boxObject, padding, linePadding) {

    var x_pos = parseInt(boxObject.getAttribute('x')),
    y_pos = parseInt(boxObject.getAttribute('y')),
    boxwidth = parseInt(boxObject.getAttribute('width')),
    fz = parseInt(window.getComputedStyle(textnode)['font-size']);  // We use this to calculate dy for each TSPAN.

    var line_height = fz + linePadding;

// Clone the original text node to store and display the final wrapping text.

   var wrapping = textnode.cloneNode(false);        // False means any TSPANs in the textnode will be discarded
   wrapping.setAttributeNS(null, 'x', x_pos + padding);
   wrapping.setAttributeNS(null, 'y', y_pos + padding);

// Make a copy of this node and hide it to progressively draw, measure and calculate line breaks.

   var testing = wrapping.cloneNode(false);
   testing.setAttributeNS(null, 'visibility', 'hidden');  // Comment this out to debug

   var testingTSPAN = document.createElementNS(null, 'tspan');
   var testingTEXTNODE = document.createTextNode(textnode.textContent);
   testingTSPAN.appendChild(testingTEXTNODE);

   testing.appendChild(testingTSPAN);
   var tester = document.getElementsByTagName('svg')[0].appendChild(testing);

   var words = textnode.textContent.split(" ");
   var line = line2 = "";
   var linecounter = 0;
   var testwidth;

   for (var n = 0; n < words.length; n++) {

      line2 = line + words[n] + " ";
      testing.textContent = line2;
      testwidth = testing.getBBox().width;

      if ((testwidth + 2*padding) > boxwidth) {

        testingTSPAN = document.createElementNS('http://www.w3.org/2000/svg', 'tspan');
        testingTSPAN.setAttributeNS(null, 'x', x_pos + padding);
        testingTSPAN.setAttributeNS(null, 'dy', line_height);

        testingTEXTNODE = document.createTextNode(line);
        testingTSPAN.appendChild(testingTEXTNODE);
        wrapping.appendChild(testingTSPAN);

        line = words[n] + " ";
        linecounter++;
      }
      else {
        line = line2;
      }
    }

    var testingTSPAN = document.createElementNS('http://www.w3.org/2000/svg', 'tspan');
    testingTSPAN.setAttributeNS(null, 'x', x_pos + padding);
    testingTSPAN.setAttributeNS(null, 'dy', line_height);

    var testingTEXTNODE = document.createTextNode(line);
    testingTSPAN.appendChild(testingTEXTNODE);

    wrapping.appendChild(testingTSPAN);

    testing.parentNode.removeChild(testing);
    textnode.parentNode.replaceChild(wrapping,textnode);

    return linecounter;
}

document.getElementById('original').onmouseover = function () {

    var container = document.getElementById('destination');
    var numberoflines = wraptorect(this,container,20,1);
    console.log(numberoflines);  // In case you need it

};

Assuming that files with those names exist in multiple places in the directory tree and you want to preserve all of them:

find . -type f ! -regex ".*/\(textfile.txt\|backup.tar.gz\|script.php\|database.sql\|info.txt\)" -delete

In order to be able to justify the text, you need to know the width of the image. You can just use the normal width of the image, or use a different width, but IE 6 might get cranky at you and not scale.

Here's what you need:

<style type="text/css">
#container { width: 100px; //whatever width you want }

#image {width: 100%; //fill up whole div }

#text { text-align: justify; }    
</style>

 <div id="container"> 
     <img src="" id="image" /> 
     <p id="text">oooh look! text!</p> 
 </div>

One question that the answers given so far don't seem to address: if the runtime libraries (not the OS, really) can keep track of the number of things in the array, then why do we need the delete[] syntax at all? Why can't a single delete form be used to handle all deletes?

The answer to this goes back to C++'s roots as a C-compatible language (which it no longer really strives to be.) Stroustrup's philosophy was that the programmer should not have to pay for any features that they aren't using. If they're not using arrays, then they should not have to carry the cost of object arrays for every allocated chunk of memory.

That is, if your code simply does

Foo* foo = new Foo;

then the memory space that's allocated for foo shouldn't include any extra overhead that would be needed to support arrays of Foo.

Since only array allocations are set up to carry the extra array size information, you then need to tell the runtime libraries to look for that information when you delete the objects. That's why we need to use

delete[] bar;

instead of just

delete bar;

if bar is a pointer to an array.

For most of us (myself included), that fussiness about a few extra bytes of memory seems quaint these days. But there are still some situations where saving a few bytes (from what could be a very high number of memory blocks) can be important.

Efficient solution using date as background dedicated process

In order to make this kind of translation a lot quicker...

Intro

In this post, you will find

• a Quick Demo, following this,
• some Explanations,
• a Function useable for many Un*x tools (bc, rot13, sed...).

Quick Demo

fifo=$HOME/.fifoDate-$$
mkfifo $fifo
exec 5> >(exec stdbuf -o0 date -f - +%s >$fifo 2>&1)
echo now 1>&5
exec 6< $fifo
rm $fifo
read -t 1 -u 6 now
echo $now

This must output current UNIXTIME. From there, you could compare

time for i in {1..5000};do echo >&5 "now" ; read -t 1 -u6 ans;done
real    0m0.298s
user    0m0.132s
sys     0m0.096s

and:

time for i in {1..5000};do ans=$(date +%s -d "now");done 
real    0m6.826s
user    0m0.256s
sys     0m1.364s

From more than 6 seconds to less than a half second!!(on my host).

You could check echo $ans, replace "now" by "2019-25-12 20:10:00" and so on...

Optionaly, you could, once requirement of date subprocess ended:

exec 5>&- ; exec 6<&-

Original post (detailed explanation)

Instead of running 1 fork by date to convert, run date just 1 time and do all convertion with same process (this could become a lot quicker)!:

date -f - +%s <<eof
Apr 17  2014
May 21  2012
Mar  8 00:07
Feb 11 00:09
eof
1397685600
1337551200
1520464020
1518304140

Sample:

start1=$(LANG=C ps ho lstart 1)
start2=$(LANG=C ps ho lstart $$)
dirchg=$(LANG=C date -r .)
read -p "A date: " userdate
{ read start1 ; read start2 ; read dirchg ; read userdate ;} < <(
   date -f - +%s <<<"$start1"$'\n'"$start2"$'\n'"$dirchg"$'\n'"$userdate" )

Then now have a look:

declare -p start1 start2 dirchg userdate

(may answer something like:

declare -- start1="1518549549"
declare -- start2="1520183716"
declare -- dirchg="1520601919"
declare -- userdate="1397685600"

This was done in one execution!

Using long running subprocess

We just need one fifo:

mkfifo /tmp/myDateFifo
exec 7> >(exec stdbuf -o0 /bin/date -f - +%s >/tmp/myDateFifo)
exec 8</tmp/myDateFifo
rm /tmp/myDateFifo

(Note: As process is running and all descriptors are opened, we could safely remove fifo's filesystem entry.)

Then now:

LANG=C ps ho lstart 1 $$ >&7
read -u 8 start1
read -u 8 start2
LANG=C date -r . >&7
read -u 8 dirchg

read -p "Some date: " userdate
echo >&7 $userdate
read -u 8 userdate

We could buid a little function:

mydate() {
    local var=$1;
    shift;
    echo >&7 $@
    read -u 8 $var
}

mydate start1 $(LANG=C ps ho lstart 1)
echo $start1

Or use my newConnector function

With functions for connecting MySQL/MariaDB, PostgreSQL and SQLite...

You may find them in different version on GitHub, or on my site: download or show.

wget https://raw.githubusercontent.com/F-Hauri/Connector-bash/master/shell_connector.bash

. shell_connector.bash 
newConnector /bin/date '-f - +%s' @0 0

myDate "2018-1-1 12:00" test
echo $test
1514804400

Nota: On GitHub, functions and test are separated files. On my site test are run simply if this script is not sourced.

# Exit here if script is sourced
[ "$0" = "$BASH_SOURCE" ] || { true;return 0;}
