db.setProfilingLevel(2,-1)

This worked! it logged all query info in mongod log file

Warning: Note that English is not restricted to just A-Z.

Try this to remove everything except a-z, A-Z and 0-9:

$result = preg_replace("/[^a-zA-Z0-9]+/", "", $s);

If your definition of alphanumeric includes letters in foreign languages and obsolete scripts then you will need to use the Unicode character classes.

Try this to leave only A-Z:

$result = preg_replace("/[^A-Z]+/", "", $s);

The reason for the warning is that words like résumé contains the letter é that won't be matched by this. If you want to match a specific list of letters adjust the regular expression to include those letters. If you want to match all letters, use the appropriate character classes as mentioned in the comments.

Add new column to DataTable and use column Expression property to set your Status expression.

Here you can find good example: DataColumn.Expression Property

DataTable and DataColumn Expressions in ADO.NET - Calculated Columns

UPDATE

Code sample:

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("colBestBefore", typeof(DateTime)));
dt.Columns.Add(new DataColumn("colStatus", typeof(string)));

dt.Columns["colStatus"].Expression = String.Format("IIF(colBestBefore < #{0}#, 'Ok','Not ok')", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

dt.Rows.Add(DateTime.Now.AddDays(-1));
dt.Rows.Add(DateTime.Now.AddDays(1));
dt.Rows.Add(DateTime.Now.AddDays(2));
dt.Rows.Add(DateTime.Now.AddDays(-2));

demoGridView.DataSource = dt;

UPDATE #2

dt.Columns["colStatus"].Expression = String.Format("IIF(CONVERT(colBestBefore, 'System.DateTime') < #{0}#, 'Ok','Not ok')", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

This is the ternary conditional operator, which can be used anywhere, not just the print statement. It's sometimes just called "the ternary operator", but it's not the only ternary operator, just the most common one.

Here's a good example from Wikipedia demonstrating how it works:

A traditional if-else construct in C, Java and JavaScript is written:

if (a > b) {
    result = x;
} else {
    result = y;
}

This can be rewritten as the following statement:

result = a > b ? x : y;

Basically it takes the form:

boolean statement ? true result : false result;

So if the boolean statement is true, you get the first part, and if it's false you get the second one.

Try these if that still doesn't make sense:

System.out.println(true ? "true!" : "false.");
System.out.println(false ? "true!" : "false.");

From the Wikipedia article on Java package naming:

In general, a package name begins with the top level domain name of the organization and then the organization's domain and then any subdomains, listed in reverse order. The organization can then choose a specific name for its package. Package names should be all lowercase characters whenever possible.

For example, if an organization in Canada called MySoft creates a package to deal with fractions, naming the package ca.mysoft.fractions distinguishes the fractions package from another similar package created by another company. If a US company named MySoft also creates a fractions package, but names it us.mysoft.fractions, then the classes in these two packages are defined in a unique and separate namespace.

You would want to use ->forget()

$collection->forget($key);

This error is often caused by incompatible jQuery versions. I encountered the same error with a foundation 6 repository. My repository was using jQuery 3, but foundation requires an earlier version. I then changed it and it worked.

If you look at the version of jQuery required by the foundation 5 dependencies it states "jquery": "~2.1.0".

Can you confirm that you are loading the correct version of jQuery?

I hope this helps.

To answer a more generic case, this error is noticed when you pick a function name which is already used in some built in library. For e.g., select.

A simple method to know about it is while compiling the file, the compiler will indicate the previous declaration.

Toni's answer is good, but I'd rather drop the ID and explicitly use input, that way all inputs with placeholder get the behavior:

<input type="text" placeholder="your text" />

Note that $(function(){ }); is the shorthand for $(document).ready(function(){ });:

$(function(){
    $('input').data('holder',$('input').attr('placeholder'));
    $('input').focusin(function(){
        $(this).attr('placeholder','');
    });
    $('input').focusout(function(){
        $(this).attr('placeholder',$(this).data('holder'));
    });
})

Demo.

This is just an add-on to the solution in case you want to compute not only unique values but other aggregate functions:

df.groupby(['group']).agg(['min','max','count','nunique'])

Hope you find it useful

The besty practice is to use '/' and a so called 'raw string' to define file path in Python.

path = r"C:/Test.py"

However, a normal program may not have the permission to write in the C: drive root directory. You may need to allow your program to do so, or choose something more reasonable since you probably not need to do so.

If it is asked if it is possible (not MUST), it can ask "a" to return a random number. It would be true if it generates 1, 2, and 3 sequentially.

with({_x000D_
  get a() {_x000D_
    return Math.floor(Math.random()*4);_x000D_
  }_x000D_
}){_x000D_
  for(var i=0;i<1000;i++){_x000D_
    if (a == 1 && a == 2 && a == 3){_x000D_
      console.log("after " + (i+1) + " trials, it becomes true finally!!!");_x000D_
      break;_x000D_
    }_x000D_
  }_x000D_
}

You're trying to use k (which is a list) as a key for d. Lists are mutable and can't be used as dict keys.

Also, you're never initializing the lists in the dictionary, because of this line:

if k not in d == False:

Which should be:

if k not in d == True:

Which should actually be:

if k not in d:

Try this:

X (\(Y\))? Z

return n from your main entry function will terminate your process and report to the parent process (the one that executed your process) the result of your process. 0 means SUCCESS. Other codes usually indicates a failure and its meaning.

Alternatively you could use a for loop as shown in the Groovy Docs:

def map = ['a':1, 'b':2, 'c':3]
for ( e in map ) {
    print "key = ${e.key}, value = ${e.value}"
}

/*
Result:
key = a, value = 1
key = b, value = 2
key = c, value = 3
*/

One benefit of using a for loop as opposed to an each closure is easier debugging, as you cannot hit a break point inside an each closure (when using Netbeans).

You can also do this.

//find the index of the CompanyName column
int columnIndex = thisReader.GetOrdinal("CompanyName"); 
//Get the value of the column. Will throw if the value is null.
string companyName = thisReader.GetString(columnIndex);

I have the same error and it fixed it including in the file the following

#include <stdint.h>

at the beginning of your file.

When docker kill CONTAINER_ID does not work and docker stop -t 1 CONTAINER_ID also does not work, you can try to delete the container:

docker container rm CONTAINER_ID

I had a similar issue today where containers were in a continuous restart loop.

The issue in my case was related to me being a poor engineer.

Anyway, I fixed the issue by deleting the container, fixing my code, and then rebuilding and running the container.

Hope that this helps anyone stuck with this issue in future

My version: use data attributes and Vanilla JavaScript

<div class="test-checkbox">
    Group One: <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupOne" value="Eat" />Eat</label>
    <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupOne" value="Sleep" />Sleep</label>
    <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupOne" value="Play" />Play</label>
    <br />
    Group Two: <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupTwo" value="Fat" />Fat</label>
    <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupTwo" value="Comfort" />Comfort</label>
    <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupTwo" value="Happy" />Happy</label>
</div>
<script>
    let cbxes = document.querySelectorAll('input[type="checkbox"][data-limit="only-one-in-a-group"]');
    [...cbxes].forEach((cbx) => {
        cbx.addEventListener('change', (e) => {
            if (e.target.checked)
                uncheckOthers(e.target);
        });
    });
    function uncheckOthers (clicked) {
        let name = clicked.getAttribute('name');
        // find others in same group, uncheck them
        [...cbxes].forEach((other) => {
            if (other != clicked && other.getAttribute('name') == name)
                other.checked = false;
        });
    }
</script>

This seems to happen from time to time with programs that are very sensitive to command lines, but one option is to just use the DOS path instead of the Windows path. This means that C:\Program Files\ would resolve to C:\PROGRA~1\ and generally avoid any issues with spacing.

To get the short path you can create a quick Batch file that echos the short path:

@ECHO OFF
echo %~s1

Which is then called as follows:

C:\>shortPath.bat "C:\Program Files"
C:\PROGRA~1

The .css() function doesn't queue behind running animations, it's instantaneous.

To match the behaviour that you're after, you'd need to do the following:

$(document).ready(function() {
  $("button").mouseover(function() {
    var p = $("p#44.test").css("background-color", "yellow");
    p.hide(1500).show(1500);
    p.queue(function() {
      p.css("background-color", "red");
    });
  });
});

The .queue() function waits for running animations to run out and then fires whatever's in the supplied function.

if you use runnable you can save the space to extend to any of your other class.

I had same problem. It was resolved by running same code in Administrator Console.

If youR data was in A1:C100 then:

Excel - all versions

=SUMPRODUCT(--(A1:A100="M"),--(C1:C100="Yes"))

Excel - 2007 onwards

=COUNTIFS(A1:A100,"M",C1:C100,"Yes")

Try doing this :

recipients="[email protected],[email protected],[email protected]"

And another approach, using shell here-doc :

/usr/sbin/sendmail "$recipients" <<EOF
subject:$subject
from:$from

Example Message
EOF

Be sure to separate the headers from the body with a blank line as per RFC 822.

If you are trying to reference a commit in another repo than the issue is in, you can prefix the commit short hash with reponame@.

Suppose your commit is in the repo named dev, and the GitLab issue is in the repo named test. You can leave a comment on the issue and reference the commit by dev@e9c11f0a (where e9c11f0a is the first 8 letters of the sha hash of the commit you want to link to) if that makes sense.

Use "getAlias" in Yii2

   \Yii::getAlias('@webroot')

if(['true', 'yes', '1'].includes(single_value)) {
    return  true;   
}
else if(['false', 'no', '0'].includes(single_value)) {
    return  false;  
}

if you have a string

As many said, there is no way to automatically convert without adding overheads and too much complexity, but you can reduce your typing a bit and make it look better by using lambdas if some cast will be used a bit much in a scenario. That would add a bit of function overhead call, but will make code more readable compared to long static_cast strings as can be seen below. This may not be useful project wide, but only class wide.

#include <bitset>
#include <vector>

enum class Flags { ......, Total };
std::bitset<static_cast<unsigned int>(Total)> MaskVar;
std::vector<Flags> NewFlags;

-----------
auto scui = [](Flags a){return static_cast<unsigned int>(a); };

for (auto const& it : NewFlags)
{
    switch (it)
    {
    case Flags::Horizontal:
        MaskVar.set(scui(Flags::Horizontal));
        MaskVar.reset(scui(Flags::Vertical)); break;
    case Flags::Vertical:
        MaskVar.set(scui(Flags::Vertical));
        MaskVar.reset(scui(Flags::Horizontal)); break;

   case Flags::LongText:
        MaskVar.set(scui(Flags::LongText));
        MaskVar.reset(scui(Flags::ShorTText)); break;
    case Flags::ShorTText:
        MaskVar.set(scui(Flags::ShorTText));
        MaskVar.reset(scui(Flags::LongText)); break;

    case Flags::ShowHeading:
        MaskVar.set(scui(Flags::ShowHeading));
        MaskVar.reset(scui(Flags::NoShowHeading)); break;
    case Flags::NoShowHeading:
        MaskVar.set(scui(Flags::NoShowHeading));
        MaskVar.reset(scui(Flags::ShowHeading)); break;

    default:
        break;
    }
}

If you use the moment js library it can easily be done like this -

jQuery.validator.addMethod("validDate", function(value, element) {
        return this.optional(element) || moment(value,"DD/MM/YYYY").isValid();
    }, "Please enter a valid date in the format DD/MM/YYYY");

This is what worked for me when I got a similar error in Windows; 1. Install virtualenv

pip install virtualenve

2. Create a virtualenv

   virtualenv flask

3. Navigate to Scripts and activate the virtualenv

   activate

4. Install Flask

   python -m pip install flask

5. Check if flask is installed

   python -m pip list

How about this?

JSONObject jsonObject = new JSONObject           (YOUR_JSON_STRING);
JSONObject ipinfo     = jsonObject.getJSONObject ("ipinfo");
String     ip_address = ipinfo.getString         ("ip_address");
JSONObject location   = ipinfo.getJSONObject     ("Location");
String     latitude   = location.getString       ("latitude");
System.out.println (latitude);

This sample code using "org.json.JSONObject"

this:

element.setAttribute("onclick", alert("blabla"));

should be:

element.onclick = function () {
  alert("blabla");
}

Because you call alert instead push alert as string in attribute

As Bhavik Shah says, you can do it in JAVA_OPTS, but the recommended way (as per catalina.sh) is to use CATALINA_OPTS:

#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   "run" or "debug" command is executed.
#                   Include here and not in JAVA_OPTS all options, that should
#                   only be used by Tomcat itself, not by the stop process,
#                   the version command etc.
#                   Examples are heap size, GC logging, JMX ports etc.

#   JAVA_OPTS       (Optional) Java runtime options used when any command
#                   is executed.
#                   Include here and not in CATALINA_OPTS all options, that
#                   should be used by Tomcat and also by the stop process,
#                   the version command etc.
#                   Most options should go into CATALINA_OPTS.

\begin{tikzpicture}

    \tikzstyle{every node}=[font=\small]

\end{tikzpicture}

will give you font size control on every node.

In my case I'm doing it like this:

 module SayHi {
    export default () => { console.log("Hi"); }
 }
 new SayHi();

when I have problem with WAMP apache , I use this code for find which program is using port 80.

netstat -o -n -a | findstr 0.0:80

3068 is PID, so I can find it from task manager and stop that process.

when you have tried everything else and still get the same trouble, there is a way out; however it will be tedious and need careful preparation.

Start another new project using existing files, or edit the project .csproj file if you are proficient in editing csproj (need backup). I will list steps for new project.

1. preparation:
   • note all references and their sources
   • note all included files from another project
2. rename the orginal projectname.csproj file
3. close solution/project
4. start new project using existing files(you will get errors from references)
5. add back the noted references
6. include/add existing file from other project(s)

Try to Use JSON.stringify

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

sizeof returns the size in bytes of it's argument. This is not what you want, but it can help.

Let's say you have an array:

int array[4];

If you apply sizeof to the array (sizeof(array)), it will return its size in bytes, which in this case is 4 * the size of an int, so a total of maybe 16 bytes (depending on your implementation).

If you apply sizeof to an element of the array (sizeof(array[0])), it will return its size in bytes, which in this case is the size of an int, so a total of maybe 4 bytes (depending on your implementation).

If you divide the first one by the second one, it will be: (4 * the size of an int) / (the size of an int) = 4; That's exactly what you wanted.

So this should do:

sizeof(array) / sizeof(array[0])

Now you would probably like to have a macro to encapsulate this logic and never have to think again how it should be done:

#define ARRAY_SIZE(arr) (sizeof(arr) / sizeof((arr)[0]))

You need the parentheses enclosing all the macro as in any other complex macro, and also enclosing every variable, just to avoid unexpected bugs related to operators precedence.

Now you can use it on any array like this:

int array[6];
ptrdiff_t nmemb;

nmemb = ARRAY_SIZE(array);
/* nmemb == 6 */

Remember that arguments of functions declared as arrays are not really arrays, but pointers to the first element of the array, so this will NOT work on them:

void foo(int false_array[6])
{
        ptrdiff_t nmemb;

        nmemb = ARRAY_SIZE(false_array);
        /* nmemb == sizeof(int *) / sizeof(int) */
        /* (maybe  ==2) */
}

But it can be used in functions if you pass a pointer to an array instead of just the array:

void bar(int (*arrptr)[7])
{
        ptrdiff_t nmemb;

        nmemb = ARRAY_SIZE(*arrptr);
        /* nmemb == 7 */
}

The easiest way is to include the gem 'activesupport' (or gem 'active_support').

Then, in your class you only need to

require 'active_support/core_ext/hash/slice'

and to call

params.slice(:choice1, :choice2, :choice3) # => {:choice1=>"Oh look, another one", :choice2=>"Even more strings", :choice3=>"But wait"}

I believe it's not worth it to be declaring other functions that may have bugs, and it's better to use a method that has been tweaked during last few years.

I added jstl jar in a library and added it to build path and deployment assembly but it dint worked. then i simply copied my jstl jar into lib folder inside webcontent, it worked. in eclipse lib folder in included to deployment assembly by default

Solution #1: Python builtin

use SequenceMatcher from difflib

pros: native python library, no need extra package.
cons: too limited, there are so many other good algorithms for string similarity out there.

>>> from difflib import SequenceMatcher
>>> s = SequenceMatcher(None, "abcd", "bcde")
>>> s.ratio()
0.75

Solution #2: jellyfish library

its a very good library with good coverage and few issues. it supports:
- Levenshtein Distance
- Damerau-Levenshtein Distance
- Jaro Distance
- Jaro-Winkler Distance
- Match Rating Approach Comparison
- Hamming Distance

pros: easy to use, gamut of supported algorithms, tested.
cons: not native library.

example:

>>> import jellyfish
>>> jellyfish.levenshtein_distance(u'jellyfish', u'smellyfish')
2
>>> jellyfish.jaro_distance(u'jellyfish', u'smellyfish')
0.89629629629629637
>>> jellyfish.damerau_levenshtein_distance(u'jellyfish', u'jellyfihs')
1

Simply try this, some of the answers here are not handling unicode data and data that has comma for example date.

function downloadUnicodeCSV(filename, datasource) {
    var content = '', newLine = '\r\n';
    for (var _i = 0, datasource_1 = datasource; _i < datasource_1.length; _i++) {
        var line = datasource_1[_i];
        var i = 0;
        for (var _a = 0, line_1 = line; _a < line_1.length; _a++) {
            var item = line_1[_a];
            var it = item.replace(/"/g, '""');
            if (it.search(/("|,|\n)/g) >= 0) {
                it = '"' + it + '"';
            }
            content += (i > 0 ? ',' : '') + it;
            ++i;
        }
        content += newLine;
    }
    var link = document.createElement('a');
    link.setAttribute('href', 'data:text/csv;charset=utf-8,%EF%BB%BF' + encodeURIComponent(content));

Try a usort, If you are still on PHP 5.2 or earlier, you'll have to define a sorting function first:

function sortByOrder($a, $b) {
    return $a['order'] - $b['order'];
}

usort($myArray, 'sortByOrder');

Starting in PHP 5.3, you can use an anonymous function:

usort($myArray, function($a, $b) {
    return $a['order'] - $b['order'];
});

And finally with PHP 7 you can use the spaceship operator:

usort($myArray, function($a, $b) {
    return $a['order'] <=> $b['order'];
});

To extend this to multi-dimensional sorting, reference the second/third sorting elements if the first is zero - best explained below. You can also use this for sorting on sub-elements.

usort($myArray, function($a, $b) {
    $retval = $a['order'] <=> $b['order'];
    if ($retval == 0) {
        $retval = $a['suborder'] <=> $b['suborder'];
        if ($retval == 0) {
            $retval = $a['details']['subsuborder'] <=> $b['details']['subsuborder'];
        }
    }
    return $retval;
});

If you need to retain key associations, use uasort() - see comparison of array sorting functions in the manual

Given your number

x = Decimal('40800000000.00000000000000')

Starting from Python 3,

'{:.2e}'.format(x)

is the recommended way to do it.

e means you want scientific notation, and .2 means you want 2 digits after the dot. So you will get x.xxE±n

To get the desired effect, you should place the image tag inside the same div as your text. Then set the float: left attribute on the image. Hope this helps!

$(window).bind("load", function() {
  // write your code here
});

for i in count: means for i in 7:, which won't work. The bit after the in should be of an iterable type, not a number. Try this:

for i in range(count):

I used a variation of the above but instead of printing html I built a form and submitted it to the 3rd party url:

    var mapForm = document.createElement("form");
    mapForm.target = "Map";
    mapForm.method = "POST"; // or "post" if appropriate
    mapForm.action = "http://www.url.com/map.php";

    var mapInput = document.createElement("input");
    mapInput.type = "text";
    mapInput.name = "addrs";
    mapInput.value = data;
    mapForm.appendChild(mapInput);

    document.body.appendChild(mapForm);

    map = window.open("", "Map", "status=0,title=0,height=600,width=800,scrollbars=1");

if (map) {
    mapForm.submit();
} else {
    alert('You must allow popups for this map to work.');

function[0] = 42; // version 1

may or may not insert the value 42 into the map. If the key 0 exists, then it will assign 42 to that key, overwriting whatever value that key had. Otherwise it inserts the key/value pair.

The insert functions:

function.insert(std::map<int, int>::value_type(0, 42));  // version 2
function.insert(std::pair<int, int>(0, 42));             // version 3
function.insert(std::make_pair(0, 42));                  // version 4

on the other hand, don't do anything if the key 0 already exists in the map. If the key doesn't exist, it inserts the key/value pair.

The three insert functions are almost identical. std::map<int, int>::value_type is the typedef for std::pair<const int, int>, and std::make_pair() obviously produces a std::pair<> via template deduction magic. The end result, however, should be the same for versions 2, 3, and 4.

Which one would I use? I personally prefer version 1; it's concise and "natural". Of course, if its overwriting behavior is not desired, then I would prefer version 4, since it requires less typing than versions 2 and 3. I don't know if there is a single de facto way of inserting key/value pairs into a std::map.

Another way to insert values into a map via one of its constructors:

std::map<int, int> quadratic_func;

quadratic_func[0] = 0;
quadratic_func[1] = 1;
quadratic_func[2] = 4;
quadratic_func[3] = 9;

std::map<int, int> my_func(quadratic_func.begin(), quadratic_func.end());

UPDATE
From v0.20, melt is a first order function, you can now use

df.melt(id_vars=["location", "name"], 
        var_name="Date", 
        value_name="Value")

  location    name        Date  Value
0        A  "test"    Jan-2010     12
1        B   "foo"    Jan-2010     18
2        A  "test"    Feb-2010     20
3        B   "foo"    Feb-2010     20
4        A  "test"  March-2010     30
5        B   "foo"  March-2010     25

OLD(ER) VERSIONS: <0.20

You can use pd.melt to get most of the way there, and then sort:

>>> df
  location  name  Jan-2010  Feb-2010  March-2010
0        A  test        12        20          30
1        B   foo        18        20          25
>>> df2 = pd.melt(df, id_vars=["location", "name"], 
                  var_name="Date", value_name="Value")
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
1        B   foo    Jan-2010     18
2        A  test    Feb-2010     20
3        B   foo    Feb-2010     20
4        A  test  March-2010     30
5        B   foo  March-2010     25
>>> df2 = df2.sort(["location", "name"])
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
2        A  test    Feb-2010     20
4        A  test  March-2010     30
1        B   foo    Jan-2010     18
3        B   foo    Feb-2010     20
5        B   foo  March-2010     25

(Might want to throw in a .reset_index(drop=True), just to keep the output clean.)

Note: pd.DataFrame.sort has been deprecated in favour of pd.DataFrame.sort_values.

I would like to add a data.table variant using the rank() function which provides the additional possibility to change the ordering and thus makes it a bit more flexible than the seq_len() solution and is pretty similar to row_number functions in RDBMS.

# Variant with ascending ordering
library(data.table)
dt <- data.table(df)
dt[, .( val
   , num = rank(val))
    , by = list(cat)][order(cat, num),]

    cat        val num
 1: aaa 0.05638315   1
 2: aaa 0.25767250   2
 3: aaa 0.30776611   3

You declared the constructor blowfish as this:

Blowfish(BlowfishAlgorithm algorithm);

So this line cannot exist (without further initialization later):

Blowfish _blowfish;

since you passed no parameter. It does not understand how to handle a parameter-less declaration of object "BlowFish" - you need to create another constructor for that.

Where you declare the myclass[] array as :

xClass myclass[] = new xClass[10]

, simply pass in as an argument the number of XClass elements you'll need. At that point do you know how many you will need? By declaring the array as having 10 elements, you are not declaring 10 XClass objects, you're simply creating an array with 10 elements of type xClass.

On *nix, also make sure that PYTHONPATH is configured correctly, especially that it has this format:

 .:/usr/local/lib/python

(Mind the .: at the beginning, so that it can search on the current directory, too.)

It may also be in other locations, depending on the version:

 .:/usr/lib/python
 .:/usr/lib/python2.6
 .:/usr/lib/python2.7 and etc.

This ones a little old but was high in the google ranking so I thought I would throw in the answer I found from Chrome, pdf display, Duplicate headers received from the server

Basically my problem also was that the filename contained commas. Do a replace on commas to remove them and you should be fine. My function to make a valid filename is below.

    public static string MakeValidFileName(string name)
    {
        string invalidChars = Regex.Escape(new string(System.IO.Path.GetInvalidFileNameChars()));
        string invalidReStr = string.Format(@"[{0}]+", invalidChars);
        string replace = Regex.Replace(name, invalidReStr, "_").Replace(";", "").Replace(",", "");
        return replace;
    }

This might work for you...

    var src = img.src;
    window.open(src);

Using HTTP Request verb such as GET, POST, DELETE, PUT etc... enables you to build RESTful web applications. Read about it here: http://en.wikipedia.org/wiki/Representational_state_transfer

The easiest way to see benefits from this is to look at this example. Every MVC framework has a Router/Dispatcher that maps URL-s to actionControllers. So URL like this: /blog/article/1 would invoke blogController::articleAction($id); Now this Router is only aware of the URL or /blog/article/1/

But if that Router would be aware of whole HTTP Request object instead of just URL, he could have access HTTP Request verb (GET, POST, PUT, DELETE...), and many other useful stuff about current HTTP Request.

That would enable you to configure application so it can accept the same URL and map it to different actionControllers depending on the HTTP Request verb.

For example:

if you want to retrive article 1 you can do this:

GET /blog/article/1 HTTP/1.1

but if you want to delete article 1 you will do this:

DELETE /blog/article/1 HTTP/1.1

Notice that both HTTP Requests have the same URI, /blog/article/1, the only difference is the HTTP Request verb. And based on that verb your router can call different actionController. This enables you to build neat URL-s.

Read this two articles, they might help you:

Symfony 2 - HTTP Fundamentals

Symfony 2 - Routing

These articles are about Symfony 2 framework, but they can help you to figure out how does HTTP Requests and Responses work.

Hope this helps!

I usually create views to de-normalize and/or aggregate data frequently used for reporting purposes.

EDIT

By way of elaboration, if I were to have a database in which some of the entities were person, company, role, owner type, order, order detail, address and phone, where the person table stored both employees and contacts and the address and phone tables stored phone numbers for both persons and companies, and the development team were tasked with generating reports (or making reporting data accessible to non-developers) such as sales by employee, or sales by customer, or sales by region, sales by month, customers by state, etc I would create a set of views that de-normalized the relationships between the database entities so that a more integrated view (no pun intended) of the real world entities was available. Some of the benefits could include:

1. Reducing redundancy in writing queries
2. Establishing a standard for relating entities
3. Providing opportunities to evaluate and maximize performance for complex calculations and joins (e.g. indexing on Schemabound views in MSSQL)
4. Making data more accessible and intuitive to team members and non-developers.

Use a document.ready() event around your call.

$(document).ready(function () {

I had same problem with Eclipse 3.7.2 (Indigo) and maven 3.0.4.

In my case, the problem was caused by missing maven-resources-plugin-2.4.3.jar in {user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\2.4.3 folder. (no idea why maven didn't update it)

Solution:

1.) add dependency to pom.xml

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.4.3</version>
</dependency>

2.) run mvn install from Eclipse or from command line

3.) refresh the project in eclipse (F5)

4.) run Maven > Update Project Configuration... on project (right click)

JAR file is downloaded to local repository and there are no errors in WS.

I just want to add a note to the answer by @Snicolas. The following steps can be used to check stop service with/without calling onDestroy().

1. onDestroy() called: Go to Settings -> Application -> Running Services -> Select and stop your service.

2. onDestroy() not Called: Go to Settings -> Application -> Manage Applications -> Select and "Force Stop" your application in which your service is running. However, as your application is stopped here, so definitely the service instances will also be stopped.

Finally, I would like to mention that the approach mentioned there using a static variable in singleton class is working for me.

Integrated Security = False : User ID and Password are specified in the connection. Integrated Security = true : the current Windows account credentials are used for authentication.

Integrated Security = SSPI : this is equivalant to true.

We can avoid the username and password attributes from the connection string and use the Integrated Security

Why not use a Pivot?

Sample Table Filter Pivot

$("a.more").click(function() {
                 $.fancybox({
                  'padding'             : 0,
                  'autoScale'   : false,
                  'transitionIn'        : 'none',
                  'transitionOut'       : 'none',
                  'title'               : this.title,
                  'width'               : 680,
                  'height'              : 495,
                  'href'                : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'),
                  'type'                : 'swf',    // <--add a comma here
                  'swf'                 : {'allowfullscreen':'true'} // <-- flashvars here
                  });
                 return false;

            }); 

You can use data-* attribute to embed custom data. The data-* attributes gives us the ability to embed custom data attributes on all HTML elements.

jQuery .data() method allows you to get/set data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks.

jQuery .attr() method get/set attribute value for only the first element in the matched set.

Example:

<span id="test" title="foo" data-kind="primary">foo</span>

$("#test").attr("title");
$("#test").attr("data-kind");
$("#test").data("kind");
$("#test").data("value", "bar");

You can do something like this:

public class Example
{
    public String name;
    public String location;

    public String[] getExample()
    {
        String ar[] = new String[2];
        ar[0]= name;
        ar[1] =  location;
        return ar; //returning two values at once
    }
}

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

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

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

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

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

With the adoption of CoreSimulator in Xcode 6.0, the data directories are per-device rather than per-version. The data directory is ~/Library/Developer/CoreSimulator/Devices//data where can be determined from 'xcrun simctl list'

Note that you can safely delete ~/Library/Application Support/iPhone Simulator and ~/Library/Logs/iOS Simulator if you don't plan on needing to roll back to Xcode 5.x or earlier.

Here is a more comprehensive method that can also accept full month names

def month_string_to_number(string):
    m = {
        'jan': 1,
        'feb': 2,
        'mar': 3,
        'apr':4,
         'may':5,
         'jun':6,
         'jul':7,
         'aug':8,
         'sep':9,
         'oct':10,
         'nov':11,
         'dec':12
        }
    s = string.strip()[:3].lower()

    try:
        out = m[s]
        return out
    except:
        raise ValueError('Not a month')

example:

>>> month_string_to_number("October")
10 
>>> month_string_to_number("oct")
10

If it's a server socket, you should call listen() on your socket, and then getsockname() to find the port number on which it is listening:

struct sockaddr_in sin;
socklen_t len = sizeof(sin);
if (getsockname(sock, (struct sockaddr *)&sin, &len) == -1)
    perror("getsockname");
else
    printf("port number %d\n", ntohs(sin.sin_port));

As for the IP address, if you use INADDR_ANY then the server socket can accept connections to any of the machine's IP addresses and the server socket itself does not have a specific IP address. For example if your machine has two IP addresses then you might get two incoming connections on this server socket, each with a different local IP address. You can use getsockname() on the socket for a specific connection (which you get from accept()) in order to find out which local IP address is being used on that connection.

For user configuration I've noticed a tendency towards moving away from individual ~/.myprogramrc to a structure below ~/.config. For example, Qt 4 uses ~/.config/<vendor>/<programname> with the default settings of QSettings. The major desktop environments KDE and Gnome use a file structure below a specific folder too (not sure if KDE 4 uses ~/.config, XFCE does use ~/.config).

To remove untracked files / directories do:

git clean -fdx

-f - force

-d - directories too

-x - remove ignored files too ( don't use this if you don't want to remove ignored files)

It is not a problem with Eclipse. If you are using the Properties class to read and store the properties file, the class will escape all special characters.

From the class documentation:

When saving properties to a stream or loading them from a stream, the ISO 8859-1 character encoding is used. For characters that cannot be directly represented in this encoding, Unicode escapes are used; however, only a single 'u' character is allowed in an escape sequence. The native2ascii tool can be used to convert property files to and from other character encodings.

From the API, store() method:

Characters less than \u0020 and characters greater than \u007E are written as \uxxxx for the appropriate hexadecimal value xxxx.

result = bytes.fromhex(some_hex_string)

From Crockford

By convention, we make a private that variable. This is used to make the object available to the private methods. This is a workaround for an error in the ECMAScript Language Specification which causes this to be set incorrectly for inner functions.

JS Fiddle

    this.myName = name;

    function returnMe() {
        return this;        //scope is lost because of the inner function
    }

    return {
        returnMe : returnMe
    }
}

function usesThat(name) {
    var that = this;
    this.myName = name;

    function returnMe() {
        return that;            //scope is baked in with 'that' to the "class"
    }

    return {
        returnMe : returnMe
    }
}

var usesthat = new usesThat('Dave');
var usesthis = new usesThis('John');
alert("UsesThat thinks it's called " + usesthat.returnMe().myName + '\r\n' +
      "UsesThis thinks it's called " + usesthis.returnMe().myName);

This alerts...

UsesThat thinks it's called Dave

UsesThis thinks it's called undefined

i'm not sure what you're expecting this to refer to in your example.. here's an alternative method:

As GvS said, but I also find it useful to use strongly typed views so that I can write something like

@Html.Partial(MVC.Student.Index(), model)

To delete a web property, you simply need to delete every profile within the property. Once the last profile has been deleted, the web property with cease to exist in the GA account. That's all there is to it! -- Source

The TextBoxFor is a newer MVC input extension introduced in MVC2.

The main benefit of the newer strongly typed extensions is to show any errors / warnings at compile-time rather than runtime.

Things like having %PATH% or spaces between items in your path will break it. Be warned.

Yes, windows paths that include spaces will cause errors. For example an application added this to the front of the system %PATH% variable definition:

C:\Program Files (x86)\WebEx\Productivity Tools;C:\Sybase\IQ-16_0\Bin64;

which caused all of the paths in %PATH% to not be set in the cmd window.

My solution is to demarcate the extended path variable in double quotes where needed:

"C:\Program Files (x86)\WebEx\Productivity Tools";C:\Sybase\IQ-16_0\Bin64;

The spaces are therefore ignored and the full path variable is parsed properly.

I encountered this issue, but on a large project where HTML changes had to be requested and became a whole issue, so I was looking for a pure css solution.

By placing position:relative; z-index:-1 on my main body content my header drop down content suddenly displayed above the body content in ie7 (it was already displaying without issue in all other browsers and in ie8+)

The problem with that was then this disabled all hover and click actions on all content in the element with the z-index:-1 so i went to the parent element of the whole page and gave it a position:relative; z-index:1

Which fixed the issue and retained the correct layering functionality.

Feels a bit hacky, but worked as required.

If you only want to change form's action, I prefer changing action on-form-submit, rather than on-input-change. It fires only once.

$('#search-form').submit(function(){
  var formAction = $("#selectsearch").val() == "people" ? "user" : "content";
  $("#search-form").attr("action", "/search/" + formAction);
}); 

So your array is structured like this (I'm gonna talk in pseudocode because my C#-fu is weak, but I hope you get the gist of what I'm saying)

string values[rows][columns]

So value[1][3] is the value at row 1, column 3.

You want to sort by column, so the problem is that your array is off by 90 degrees.

As a first cut, could you just rotate it?

std::string values_by_column[columns][rows];

for (int i = 0; i < rows; i++)
  for (int j = 0; j < columns; j++)
    values_by_column[column][row] = values[row][column]

sort_array(values_by_column[column])

for (int i = 0; i < rows; i++)
  for (int j = 0; j < columns; j++)
    values[row][column] = values_by_column[column][row]

If you know you only want to sort one column at a time, you could optimize this a lot by just extracting the data you want to sort:

  string values_to_sort[rows]
  for (int i = 0; i < rows; i++)
    values_to_sort[i] = values[i][column_to_sort]

  sort_array(values_to_sort)

  for (int i = 0; i < rows; i++)
    values[i][column_to_sort] = values_to_sort[i]

In C++ you could play tricks with how to calculate offsets into the array (since you could treat your two-dimensional array as a one-d array) but I'm not sure how to do that in c#.

I'm assuming Windows if you're using WAMP. Composer likely is just using the PHP set in your path: How to access PHP with the Command Line on Windows?

You should be able to change the path to PHP using the same instructions.

Otherwise, composer is just a PHAR file, you can download the PHAR and execute it using any PHP:

C:\full\path\to\php.exe C:\full\path\to\composer.phar install

In Linux, there is different escape sequences for control terminal. For example, there is special escape sequence for erase whole line: \33[2K and for move cursor to previous line: \33[1A. So all you need is to print this every time you need to refresh the line. Here is the code which prints Line 1 (second variant):

System.out.println("Line 1 (first variant)");
System.out.print("\33[1A\33[2K");
System.out.println("Line 1 (second variant)");

There are codes for cursor navigation, clearing screen and so on.

I think there are some libraries which helps with it (ncurses?).

You will certainly be able to do that using WITH clause, or use analytic functions available in Oracle SQL.

With some effort you'd be able to get anything out of them in terms of cycles as in ordinary procedural languages. Both approaches are pretty powerful compared to ordinary SQL.

http://www.dba-oracle.com/t_with_clause.htm

http://www.orafaq.com/node/55

It requires some effort though. Don't be afraid to post a concrete example.

Using simple pseudo table DUAL helps too.

The ~/Library/Developer/Xcode/iOS DeviceSupport folder is basically only needed to symbolicate crash logs.

You could completely purge the entire folder. Of course the next time you connect one of your devices, Xcode would redownload the symbol data from the device.

I clean out that folder once a year or so by deleting folders for versions of iOS I no longer support or expect to ever have to symbolicate a crash log for.

I combined what I found the best from several answers and comments.

• Random initialization vector prepended to crypto text (@jbtule)
• Use TransformFinalBlock() instead of MemoryStream (@RenniePet)
• No pre-filled keys to avoid anyone copy & pasting a disaster

You must not have made jQuery available to your script.

Add this to the top of your file:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"></script>

This issue is related to the jQuery/JavaScript file not added to the PHP/JSP/ASP file properly. This goes out and gets the jQuery code from the source. You could download that and reference it locally on the server which would be faster.

Or either one can directly link it to jQuery or GoogleCDN or MicrosoftCDN.

How do add jQuery to your webpage

You can align text anywhere in the scaffold or container except center:-

Its works for me anywhere in my application:-

new Text(

                "Nextperience",

//i have setted in center.

                textAlign: TextAlign.center,

//when i want it left.

 //textAlign: TextAlign.left,

//when i want it right.

 //textAlign: TextAlign.right,

                style: TextStyle(

                    fontSize: 16,

                    color: Colors.blue[900],

                    fontWeight: FontWeight.w500),

              ), 

When you overload in TypeScript, you only have one implementation with multiple signatures.

class Foo {
    myMethod(a: string);
    myMethod(a: number);
    myMethod(a: number, b: string);
    myMethod(a: any, b?: string) {
        alert(a.toString());
    }
}

Only the three overloads are recognized by TypeScript as possible signatures for a method call, not the actual implementation.

In your case, I would personally use two methods with different names as there isn't enough commonality in the parameters, which makes it likely the method body will need to have lots of "ifs" to decide what to do.

TypeScript 1.4

As of TypeScript 1.4, you can typically remove the need for an overload using a union type. The above example can be better expressed using:

myMethod(a: string | number, b?: string) {
    alert(a.toString());
}

The type of a is "either string or number".

The default display property for a table is display:table;. The only other useful value is inline-table. All other display values are invalid for table elements.

There isn't an auto option to reset it to default, although if you're working in Javascript, you can set it to an empty string, which will do the trick.

width:auto; is valid, but isn't the default. The default width for a table is 100%, whereas width:auto; will make the element only take up as much width as it needs to.

min-width:auto; isn't allowed. If you set min-width, it must have a value, but setting it to zero is probably as good as resetting it to default.

There is nothing more DRY than

.btn {
    margin-bottom:5px;
}

I'm surprised no one mentioned mapping the file into memory: mmap

With this you can access the file as if it were already loaded into memory and the OS will take care of mapping it in and out as possible. Also, if you do this from 2 independent processes and they map the file "shared", they will share the underlying memory.

Once mapped, it will behave like a bytearray. You can use regular expressions, find or any of the other common methods.

Beware that this approach is a little OS specific. It will not be automatically portable.

if you want a structured solution (like ORM) then JAXB2 is a good solution.

If you want a serialization like DOT NET then you could use Long Term Persistence of JavaBeans Components

The choice depends on use of serialization.

You can use the hide and show functions of jquery. Examples

In your case just set $('#msform').hide() or $('#msform').show()

I suggest 2 more options:

integers.values().stream().mapToInt(Integer::intValue).sum();
integers.values().stream().collect(Collectors.summingInt(Integer::intValue));

The second one uses Collectors.summingInt() collector, there is also a summingLong() collector which you would use with mapToLong.

And a third option: Java 8 introduces a very effective LongAdder accumulator designed to speed-up summarizing in parallel streams and multi-thread environments. Here, here's an example use:

LongAdder a = new LongAdder();
map.values().parallelStream().forEach(a::add);
sum = a.intValue();

I think this code will work because a placeholder is needed only for input type text. So this one line CSS will be enough for your need:

input[type="text"]::-webkit-input-placeholder {
    color: red;
}

import has from 'lodash/has'; is better because lodash holds all it's functions in a single file, so rather than import the whole 'lodash' library at 100k, it's better to just import lodash's has function which is maybe 2k.

Someone's going to post a much better answer than this, but just wanted to make the point that personally I would never store a phone number in any kind of integer field, mainly because:

1. You don't need to do any kind of arithmetic with it, and
2. Sooner or later someone's going to try to (do something like) put brackets around their area code.

In general though, I seem to almost exclusively use:

• INT(11) for anything that is either an ID or references another ID
• DATETIME for time stamps
• VARCHAR(255) for anything guaranteed to be under 255 characters (page titles, names, etc)
• TEXT for pretty much everything else.

Of course there are exceptions, but I find that covers most eventualities.

You can just use empty() - as seen in the documentation, it will return false if the variable has no value.

An example on that same page:

<?php
$var = 0;

// Evaluates to true because $var is empty
if (empty($var)) {
    echo '$var is either 0, empty, or not set at all';
}

// Evaluates as true because $var is set
if (isset($var)) {
    echo '$var is set even though it is empty';
}
?>

You can use isset if you just want to know if it is not NULL. Otherwise it seems empty() is just fine to use alone.

I'm not sure I understand your question, but if you want the image to fill the entire screen you can use a DecorationImage with a fit of BoxFit.cover.

class BaseLayout extends StatelessWidget{
  @override
  Widget build(BuildContext context){
    return Scaffold(
      body: Container(
        decoration: BoxDecoration(
          image: DecorationImage(
            image: AssetImage("assets/images/bulb.jpg"),
            fit: BoxFit.cover,
          ),
        ),
        child: null /* add child content here */,
      ),
    );
  }
}

For your second question, here is a link to the documentation on how to embed resolution-dependent asset images into your app.

simply you can use jquery plugin to get/set the content of the div.

var divContent = $('#'DIV1).html(); $('#'DIV2).html(divContent );

for this you need to include jquery library.

For me, setting JAVA_HOME did the trick (instead of unsetting, as in another answer given here). Either in Windows:

set JAVA_HOME="C:\Program Files\Java\jre7\"

Or inside R:

Sys.setenv(JAVA_HOME="C:\\Program Files\\Java\\jre7\\")

But what's probably the best solution (since rJava 0.9-4) is overriding within R the Windows JAVA_HOME setting altogether:

options(java.home="C:\\Program Files\\Java\\jre7\\")
library(rJava)

You can use regexp to do this:

function isInt(data){
  if(typeof(data)=='number'){
    var patt=/^[0-9e+]+$/;
    data=data+"";
    data=data.match(patt);
    if(data==null){return false;}
     else {return true;}}
  else{return false;} 
}

It will return false if data isn't an integer, true otherwise.

create a filter.js and you can make this as reusable

angular.module('yourmodule').filter('date', function($filter)
{
    return function(input)
    {
        if(input == null){ return ""; }
        var _date = $filter('date')(new Date(input), 'dd/MM/yyyy');
        return _date.toUpperCase();
    };
});

view

<span>{{ d.time | date }}</span>

or in controller

var filterdatetime = $filter('date')( yourdate );

Date filtering and formatting in Angular js.

Extracting a specific folder (directory) within war file:

# unzip <war file> '<folder to extract/*>' -d <destination path> 
unzip app##123.war 'some-dir/*' -d extracted/

You get ./extracted/some-dir/ as a result.

Assuming dateTime1 and dateTime2 are DateTime values:

var diffInSeconds = (dateTime1 - dateTime2).TotalSeconds;

In your case, you 'd use DateTime.Now as one of the values and the time in the list as the other. Be careful of the order, as the result can be negative if dateTime1 is earlier than dateTime2.

Simply apply aggregation function, Sum on your column

df.groupby('steps').sum().show()

Follow the Documentation http://spark.apache.org/docs/2.1.0/api/python/pyspark.sql.html

Check out this link also https://www.analyticsvidhya.com/blog/2016/10/spark-dataframe-and-operations/

I needed to convert a single column of strings of form nn.n% to float. I needed to remove the % from the element in each row. The attend data frame has two columns.

attend.iloc[:,1:2]=attend.iloc[:,1:2].applymap(lambda x: float(x[:-1]))

Its an extenstion to the original answer. In my case it takes a dataframe and applies a function to each value in a specific column. The function removes the last character and converts the remaining string to float.

To get "User-Agent" and "Referer" by yourself, just go to developer mode of one of your installed browser (E.g. press F12 on Google Chrome). Then go to tab 'Network' and then click on one of the requests. You should see it's details. Just press 'Headers' sub tab (the image below)

I faced same issue & it resolved by

ENTRYPOINT ["sh", "/docker-entrypoint.sh"]

For the Dockerfile in the original question it should be like:

ENTRYPOINT ["sh", "/usr/src/app/docker-entrypoint.sh"]

I'm not sure why you think the documentation is vague.

It simply goes through all the parameters one by one, and returns the first that is NOT NULL.

COALESCE(NULL, NULL, NULL, 1, 2, 3)
=> 1


COALESCE(1, 2, 3, 4, 5, NULL)
=> 1


COALESCE(NULL, NULL, NULL, 3, 2, NULL)
=> 3


COALESCE(6, 5, 4, 3, 2, NULL)
=> 6


COALESCE(NULL, NULL, NULL, NULL, NULL, NULL)
=> NULL

It accepts pretty much any number of parameters, but they should be the same data-type. (If they're not the same data-type, they get implicitly cast to an appropriate data-type using data-type order of precedence.)

It's like ISNULL() but for multiple parameters, rather than just two.

It's also ANSI-SQL, where-as ISNULL() isn't.

To show the div while selecting one value and hide while selecting another value from dropdown box: -

 $('#yourselectorid').bind('change', function(event) {

           var i= $('#yourselectorid').val();

            if(i=="sometext") // equal to a selection option
             {
                 $('#divid').show();
             }
           elseif(i=="othertext")
             {
               $('#divid').hide(); // hide the first one
               $('#divid2').show(); // show the other one

              }
});

You can use git log with the pathnames of the respective folders:

git log A B

The log will only show commits made in A and B. I usually throw in --stat to make things a little prettier, which helps for quick commit reviews.

Previous answers cover about ASCII character at a certain index.

It is a little bit troublesome to get a Unicode character at a certain index in Python 2.

E.g., with s = '????????' which is <type 'str'>,

__getitem__, e.g., s[i] , does not lead you to where you desire. It will spit out semething like ?. (Many Unicode characters are more than 1 byte but __getitem__ in Python 2 is incremented by 1 byte.)

In this Python 2 case, you can solve the problem by decoding:

s = '????????'
s = s.decode('utf-8')
for i in range(len(s)):
    print s[i]

In IPython %history -g should give you the entire command history. The default configuration also saves your history into a file named .python_history in your user directory.

It is just to initialize the instance's variables.

E.g. create a crawler instance with a specific database name (from your example above).

Answering this for Ubuntu users for reference.

Run command google-chrome --app-url "http://localhost/"

Replace your desired URL in the parameter.

You can get more options like incognito mode etc. Run google-chrome --help to see the options.

Switch to the develop branch:

$ git checkout develop

Creates feature/foo branch of develop.

$ git checkout -b feature/foo develop

merge the changes to develop without a fast-forward

$ git checkout develop
$ git merge --no-ff myFeature

Now push changes to the server

$ git push origin develop
$ git push origin feature/foo

With unsigned numbers of type unsigned int or larger, in the absence of type conversions, a-b is defined as yielding the unsigned number which, when added to b, will yield a. Conversion of a negative number to unsigned is defined as yielding the number which, when added to the sign-reversed original number, will yield zero (so converting -5 to unsigned will yield a value which, when added to 5, will yield zero).

Note that unsigned numbers smaller than unsigned int may get promoted to type int before the subtraction, the behavior of a-b will depend upon the size of int.

Perhaps a little off topic, just be informed that these kind of messages can also be seen when you are debugging your code with a breakpoint inside an async function like setTimeout like below:

[Violation] 'setTimeout' handler took 43129ms

That number (43129ms) depends on how long you stop in your async function

GetType() exists on every single framework type, because it is defined on the base object type. So, regardless of the type itself, you can use it to return the underlying Type

So, all you need to do is:

u.GetType() == t

you can use update from...

something like:

update shipment set.... from shipment inner join ProfilerTest.dbo.BookingDetails on ...

PHP 5.3+ solution.

$new_time = DateTime::createFromFormat('h:i A', '01:00 PM');
$time_24 = $new_time->format('H:i:s');

Output: 13:00:00

Works great when formatting date is required. Check This Answer for details.

I too had both OWIN as well as my WebAPI that both apparently needed CORS enabled separately which in turn created the 'Access-Control-Allow-Origin' header contains multiple values error.

I ended up removing ALL code that enabled CORS and then added the following to the system.webServer node of my Web.Config:

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="https://stethio.azurewebsites.net" />
    <add name="Access-Control-Allow-Methods" value="GET, POST, OPTIONS, PUT, DELETE" />
    <add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept, Authorization" />
  </customHeaders>
</httpProtocol>

Doing this satisfied CORS requirements for OWIN (allowing log in) and for WebAPI (allowing API calls), but it created a new problem: an OPTIONS method could not be found during preflight for my API calls. The fix for that was simple--I just needed to remove the following from the handlers node my Web.Config:

<remove name="OPTIONSVerbHandler" />

Hope this helps someone.

This is an old question so I don't see a Java 8 equivalent. Here is an example for this specific case.

import java.util.Collections;
import java.util.Comparator;
import java.util.List;

/**

public class SimpleJava8ComparatorClass {

        reportList.add(new Report("reportKey3", "studentNumber2", "school4"));

                   ", studentNumber='" + studentNumber + '\'' +
                   ", school='" + school + '\'' +
                   '}';
        }
    }
}

random.randrange(0,2) this works!

1. Include the Open Graph XML namespace extension to your HTML declaration

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:fb="http://ogp.me/ns/fb#">

2. Inside your <head></head> use the following meta tag to define the image you want to use

<meta property="og:image" content="fully_qualified_image_url_here" />

Read more about open graph protocol here.

After doing the above, use the Facebook "Object Debugger" if the image does not show up correctly. Also note the first time shared it still won't show up unless height and width are also specified, see Share on Facebook - Thumbnail not showing for the first time

This is a working script that will scroll the page to the anchor. To setup just give the anchor link an id that matches the name attribute of the anchor that you want to scroll to.

<script>
jQuery(document).ready(function ($){ 
 $('a').click(function (){ 
  var id = $(this).attr('id');
  console.log(id);
  if ( id == 'cet' || id == 'protein' ) {
   $('html, body').animate({ scrollTop: $('[name="' + id + '"]').offset().top}, 'slow'); 
  }
 }); 
});
</script>

This link describes how you can add a progress event listener to the xhr object using jquery.

$.ajax({
    xhr: function() {
        var xhr = new window.XMLHttpRequest();

        // Upload progress
        xhr.upload.addEventListener("progress", function(evt){
            if (evt.lengthComputable) {
                var percentComplete = evt.loaded / evt.total;
                //Do something with upload progress
                console.log(percentComplete);
            }
       }, false);
       
       // Download progress
       xhr.addEventListener("progress", function(evt){
           if (evt.lengthComputable) {
               var percentComplete = evt.loaded / evt.total;
               // Do something with download progress
               console.log(percentComplete);
           }
       }, false);
       
       return xhr;
    },
    type: 'POST',
    url: "/",
    data: {},
    success: function(data){
        // Do something success-ish
    }
});

Use this style to change only the nested lists:

ol {
    counter-reset: item;
}

ol > li {
    counter-increment: item;
}

ol ol > li {
    display: block;
}

ol ol > li:before {
    content: counters(item, ".") ". ";
    margin-left: -20px;
}

To get your program to run, please put jsp files under web-content and not under WEB-INF because in Eclipse the files are not accessed there by the server, so try starting the server and browsing to URL:

http://localhost:8080/YourProject/yourfile.jsp

then your problem will be solved.

you can use this code to open (test.xlsx) file and modify A1 cell and then save it with a new name

import openpyxl
xfile = openpyxl.load_workbook('test.xlsx')

sheet = xfile.get_sheet_by_name('Sheet1')
sheet['A1'] = 'hello world'
xfile.save('text2.xlsx')

 <?php
$array["a"] = "Thusitha";
$array["b"] = "Sumanadasa";
$array["c"] = "Lakmal";
$array["d"] = "Nanayakkara";

$str = serialize($array);
$strenc = urlencode($str);
print $str . "\n";
print $strenc . "\n";
?> 

print $str . "\n"; gives a:4:{s:1:"a";s:8:"Thusitha";s:1:"b";s:10:"Sumanadasa";s:1:"c";s:6:"Lakmal";s:1:"d";s:11:"Nanayakkara";} and

print $strenc . "\n"; gives

a%3A4%3A%7Bs%3A1%3A%22a%22%3Bs%3A8%3A%22Thusitha%22%3Bs%3A1%3A%22b%22%3Bs%3A10%3A%22Sumanadasa%22%3Bs%3A1%3A%22c%22%3Bs%3A6%3A%22Lakmal%22%3Bs%3A1%3A%22d%22%3Bs%3A11%3A%22Nanayakkara%22%3B%7D

So if you want to pass this $array through URL to page_no_2.php,

ex:-

$url ='http://page_no_2.php?data=".$strenc."';

To return back to the original array, it needs to be urldecode(), then unserialize(), like this in page_no_2.php:

    <?php
    $strenc2= $_GET['data'];
    $arr = unserialize(urldecode($strenc2));
    var_dump($arr);
    ?>

gives

 array(4) {
  ["a"]=>
  string(8) "Thusitha"
  ["b"]=>
  string(10) "Sumanadasa"
  ["c"]=>
  string(6) "Lakmal"
  ["d"]=>
  string(11) "Nanayakkara"
}

again :D

jQuery has some issues loading binary data using AJAX requests, as it does not yet implement some HTML5 XHR v2 capabilities, see this enhancement request and this discussion

Given that, you have one of two solutions:

First solution, abandon JQuery and use XMLHTTPRequest

Go with the native HTMLHTTPRequest, here is the code to do what you need

  var req = new XMLHttpRequest();
  req.open("GET", "/file.pdf", true);
  req.responseType = "blob";

  req.onload = function (event) {
    var blob = req.response;
    console.log(blob.size);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="Dossier_" + new Date() + ".pdf";
    link.click();
  };

  req.send();

Second solution, use the jquery-ajax-native plugin

The plugin can be found here and can be used to the XHR V2 capabilities missing in JQuery, here is a sample code how to use it

$.ajax({
  dataType: 'native',
  url: "/file.pdf",
  xhrFields: {
    responseType: 'blob'
  },
  success: function(blob){
    console.log(blob.size);
      var link=document.createElement('a');
      link.href=window.URL.createObjectURL(blob);
      link.download="Dossier_" + new Date() + ".pdf";
      link.click();
  }
});

The string $chain is in the same character encoding as the characters in the array - it's possible, even likely, that the $first_name string is in a different encoding, and so those characters don't match. You might want to try using the multibyte string functions instead.

Try mb_convert_encoding. You might also want to try using HTML_ENTITIES as the to_encoding parameter, then you don't need to worry about how the characters will get converted - it will be very predictable.

Assuming your input to this script is in UTF-8, probably not a bad place to start...

$first_name = mb_convert_encoding($first_name, "HTML-ENTITIES", "UTF-8"); 

If you have

<base href="/" />

It's will not load file right. Just delete it.

You never really specified how you wanted them disabled, or what would cause the disabling.

First, you want to figure out how to set the value to disabled, for that you would use JQuery's Attribute Functions, and have that function happen on an event, like a click, or the loading of the document.

ES6+ version for 2021; no 1MB limit either:

This is adapted from @maia's version, updated for modern Javascript with the deprecated initMouseEvent replaced by new MouseEvent() and the code generally improved:

const saveTemplateAsFile = (filename, jsonToWrite) => {
    const blob = new Blob([jsonToWrite], { type: "text/json" });
    const link = document.createElement("a");

    link.download = filename;
    link.href = window.URL.createObjectURL(blob);
    link.dataset.downloadurl = ["text/json", link.download, link.href].join(":");

    const evt = new MouseEvent("click", {
        view: window,
        bubbles: true,
        cancelable: true,
    });

    link.dispatchEvent(evt);
};

If you want to pass an object in:

const myObj = {};
const myObjAsJson = JSON.stringify(myObj);

saveTemplateAsFile(myObjAsJson);

You have to know the encoding of the string represented in bytes, but you can say System.Text.UTF8Encoding.GetString(bytes) or System.Text.ASCIIEncoding.GetString(bytes). (I'm doing this from memory, so the API may not be exactly correct, but it's very close.)

For the answer to your second question, see this question.

I encountered difficulties with Roi-Kyi Bryant's solution when multiple add-ins tried to modify the ribbon. I also don't have admin access on my work-computer, which ruled out installing the Custom UI Editor. So, if you're in the same boat as me, here's an alternative example to customising the ribbon using only Excel. Note, my solution is derived from the Microsoft guide.

1. Create Excel file/files whose ribbons you want to customise. In my case, I've created two .xlam files, Chart Tools.xlam and Priveleged UDFs.xlam, to demonstrate how multiple add-ins can interact with the Ribbon.
2. Create a folder, with any folder name, for each file you just created.
3. Inside each of the folders you've created, add a customUI and _rels folder.
4. Inside each customUI folder, create a customUI.xml file. The customUI.xml file details how Excel files interact with the ribbon. Part 2 of the Microsoft guide covers the elements in the customUI.xml file.

My customUI.xml file for Chart Tools.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:chartToolsTab" label="Chart Tools">
        <group id="relativeChartMovementGroup" label="Relative Chart Movement" >
            <button id="moveChartWithRelativeLinksButton" label="Copy and Move" imageMso="ResultsPaneStartFindAndReplace" onAction="MoveChartWithRelativeLinksCallBack" visible="true" size="normal"/>
            <button id="moveChartToManySheetsWithRelativeLinksButton" label="Copy and Distribute" imageMso="OutlineDemoteToBodyText" onAction="MoveChartToManySheetsWithRelativeLinksCallBack" visible="true" size="normal"/>
        </group >
        <group id="chartDeletionGroup" label="Chart Deletion">
            <button id="deleteAllChartsInWorkbookSharingAnAddressButton" label="Delete Charts" imageMso="CancelRequest" onAction="DeleteAllChartsInWorkbookSharingAnAddressCallBack" visible="true" size="normal"/>
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

My customUI.xml file for Priveleged UDFs.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:privelgedUDFsTab" label="Privelged UDFs">
        <group id="privelgedUDFsGroup" label="Toggle" >
            <button id="initialisePrivelegedUDFsButton" label="Activate" imageMso="TagMarkComplete" onAction="InitialisePrivelegedUDFsCallBack" visible="true" size="normal"/>
            <button id="deInitialisePrivelegedUDFsButton" label="De-Activate" imageMso="CancelRequest" onAction="DeInitialisePrivelegedUDFsCallBack" visible="true" size="normal"/>
        </group >
      </tab>
    </tabs>
  </ribbon>
</customUI>

5. For each file you created in Step 1, suffix a .zip to their file name. In my case, I renamed Chart Tools.xlam to Chart Tools.xlam.zip, and Privelged UDFs.xlam to Priveleged UDFs.xlam.zip.
6. Open each .zip file, and navigate to the _rels folder. Copy the .rels file to the _rels folder you created in Step 3. Edit each .rels file with a text editor. From the Microsoft guide

Between the final <Relationship> element and the closing <Relationships> element, add a line that creates a relationship between the document file and the customization file. Ensure that you specify the folder and file names correctly.

<Relationship Type="http://schemas.microsoft.com/office/2006/
  relationships/ui/extensibility" Target="/customUI/customUI.xml" 
  Id="customUIRelID" />

My .rels file for Chart Tools.xlam looks like this

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="chartToolsCustomUIRel" />
    </Relationships>

My .rels file for Priveleged UDFs looks like this.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="privelegedUDFsCustomUIRel" />
    </Relationships>

7. Replace the .rels files in each .zip file with the .rels file/files you modified in the previous step.
8. Copy and paste the .customUI folder you created into the home directory of the .zip file/files.
9. Remove the .zip file extension from the Excel files you created.
10. If you've created .xlam files, back in Excel, add them to your Excel add-ins.
11. If applicable, create callbacks in each of your add-ins. In Step 4, there are onAction keywords in my buttons. The onAction keyword indicates that, when the containing element is triggered, the Excel application will trigger the sub-routine encased in quotation marks directly after the onAction keyword. This is known as a callback. In my .xlam files, I have a module called CallBacks where I've included my callback sub-routines.

My CallBacks module for Chart Tools.xlam looks like

Option Explicit

Public Sub MoveChartWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartWithRelativeLinks
End Sub

Public Sub MoveChartToManySheetsWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartToManySheetsWithRelativeLinks
End Sub

Public Sub DeleteAllChartsInWorkbookSharingAnAddressCallBack(ByRef control As IRibbonControl)
  DeleteAllChartsInWorkbookSharingAnAddress
End Sub

My CallBacks module for Priveleged UDFs.xlam looks like

Option Explicit

Public Sub InitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.InitialisePrivelegedUDFs
End Sub

Public Sub DeInitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.DeInitialisePrivelegedUDFs
End Sub

Different elements have a different callback sub-routine signature. For buttons, the required sub-routine parameter is ByRef control As IRibbonControl. If you don't conform to the required callback signature, you will receive an error while compiling your VBA project/projects. Part 3 of the Microsoft guide defines all the callback signatures.

Here's what my finished example looks like

Some closing tips

1. If you want add-ins to share Ribbon elements, use the idQ and xlmns: keyword. In my example, the Chart Tools.xlam and Priveleged UDFs.xlam both have access to the elements with idQ's equal to x:chartToolsTab and x:privelgedUDFsTab. For this to work, the x: is required, and, I've defined its namespace in the first line of my customUI.xml file, <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.
2. If you want add-ins to access Ribbon elements shipped with Excel, use the isMSO keyword. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.

Through this you can get absolute path of any file located in any directory.

File.join(Dir.pwd,'some-dir','some-file-name')

This will return

=> "/User/abc/xyz/some-dir/some-file-name"

Boilerplate code means a piece of code which can be used over and over again. On the other hand, anyone can say that it's a piece of reusable code.

The term actually came from the steel industries.

For a little bit of history, according to Wikipedia:

In the 1890s, boilerplate was actually cast or stamped in metal ready for the printing press and distributed to newspapers around the United States. Until the 1950s, thousands of newspapers received and used this kind of boilerplate from the nation's largest supplier, the Western Newspaper Union. Some companies also sent out press releases as boilerplate so that they had to be printed as written.

Now according to Wikipedia:

In object-oriented programs, classes are often provided with methods for getting and setting instance variables. The definitions of these methods can frequently be regarded as boilerplate. Although the code will vary from one class to another, it is sufficiently stereotypical in structure that it would be better generated automatically than written by hand. For example, in the following Java class representing a pet, almost all the code is boilerplate except for the declarations of Pet, name and owner:

public class Pet {
    private PetName name;
    private Person owner;

    public Pet(PetName name, Person owner) {
        this.name = name;
        this.owner = owner;
    }

    public PetName getName() {
        return name;
    }

    public void setName(PetName name) {
        this.name = name;
    }

    public Person getOwner() {
        return owner;
    }

    public void setOwner(Person owner) {
        this.owner = owner;
    }
}

You must specify the file to be downloaded (attachment) by the client in the http header:

Response.ContentType = "application/vnd.ms-excel"
Response.AppendHeader "content-disposition", "attachment: filename=excelTest.xls"

http://classicasp.aspfaq.com/general/how-do-i-prompt-a-save-as-dialog-for-an-accepted-mime-type.html

I put together, after having read the answers in this question, a simple function which can also do a callback, if you need that:

function waitFor(ms, cb) {
  var waitTill = new Date(new Date().getTime() + ms);
  while(waitTill > new Date()){};
  if (cb) {
    cb()
  } else {
   return true
  }
}

This is perfectly legal:

public static void main(String[] args) {

}

public static void main(String argv) {
    System.out.println("hello");
}

I remember from Czech book about C: read the declaration that you start with the variable and go left. So for

char * const a;

you can read as: "a is variable of type constant pointer to char",

char const * a;

you can read as: "a is a pointer to constant variable of type char. I hope this helps.

Bonus:

const char * const a;

You will read as a is constant pointer to constant variable of type char.

I'm assuming you want to still see STDERR and STDOUT on the terminal. You could go for Josh Kelley's answer, but I find keeping a tail around in the background which outputs your log file very hackish and cludgy. Notice how you need to keep an exra FD and do cleanup afterward by killing it and technically should be doing that in a trap '...' EXIT.

There is a better way to do this, and you've already discovered it: tee.

Only, instead of just using it for your stdout, have a tee for stdout and one for stderr. How will you accomplish this? Process substitution and file redirection:

command > >(tee -a stdout.log) 2> >(tee -a stderr.log >&2)

Let's split it up and explain:

> >(..)

>(...) (process substitution) creates a FIFO and lets tee listen on it. Then, it uses > (file redirection) to redirect the STDOUT of command to the FIFO that your first tee is listening on.

Same thing for the second:

2> >(tee -a stderr.log >&2)

We use process substitution again to make a tee process that reads from STDIN and dumps it into stderr.log. tee outputs its input back on STDOUT, but since its input is our STDERR, we want to redirect tee's STDOUT to our STDERR again. Then we use file redirection to redirect command's STDERR to the FIFO's input (tee's STDIN).

See http://mywiki.wooledge.org/BashGuide/InputAndOutput

Process substitution is one of those really lovely things you get as a bonus of choosing bash as your shell as opposed to sh (POSIX or Bourne).

In sh, you'd have to do things manually:

out="${TMPDIR:-/tmp}/out.$$" err="${TMPDIR:-/tmp}/err.$$"
mkfifo "$out" "$err"
trap 'rm "$out" "$err"' EXIT
tee -a stdout.log < "$out" &
tee -a stderr.log < "$err" >&2 &
command >"$out" 2>"$err"

Thank you drifty0pine!

The first solution, it´s works!

[a relative link](../../some/dir/filename.md)
[Link to file in another dir on same drive](/another/dir/filename.md)
[Link to file in another dir on a different drive](/D:/dir/filename.md)

but I had need put more ../ until the folder where was my file, like this:

[FileToOpen](../../../../folderW/folderX/folderY/folderZ/FileToOpen.txt)

If a we want to set the gravity of content inside a view then we will use "android:gravity", and if we want to set the gravity of this view (as a whole) within its parent view then we will use "android:layout_gravity".

If you have a String, you can do that:

String s = "test";
try {
    s.getBytes("UTF-8");
} catch(UnsupportedEncodingException uee) {
    uee.printStackTrace();
}

If you have a 'broken' String, you did something wrong, converting a String to a String in another encoding is defenetely not the way to go! You can convert a String to a byte[] and vice-versa (given an encoding). In Java Strings are AFAIK encoded with UTF-16 but that's an implementation detail.

Say you have a InputStream, you can read in a byte[] and then convert that to a String using

byte[] bs = ...;
String s;
try {
    s = new String(bs, encoding);
} catch(UnsupportedEncodingException uee) {
    uee.printStackTrace();
}

or even better (thanks to erickson) use InputStreamReader like that:

InputStreamReader isr;
try {
     isr = new InputStreamReader(inputStream, encoding);
} catch(UnsupportedEncodingException uee) {
    uee.printStackTrace();
}

You can use cut:

cut -c N- file.txt > new_file.txt

-c: characters

file.txt: input file

new_file.txt: output file

N-: Characters from N to end to be cut and output to the new file.

Can also have other args like: 'N' , 'N-M', '-M' meaning nth character, nth to mth character, first to mth character respectively.

This will perform the operation to each line of the input file.

convert the NULL values with empty string by wrapping it in COALESCE

SELECT CONCAT(COALESCE(`affiliate_name`,''),'-',COALESCE(`model`,''),'-',COALESCE(`ip`,''),'-',COALESCE(`os_type`,''),'-',COALESCE(`os_version`,'')) AS device_name
FROM devices

In Oracle database we can achieve like this.

CREATE TABLE Student(
  StudentID Number(38, 0) not null,
  DepartmentID Number(38, 0) not null,
  PRIMARY KEY (StudentID, DepartmentID)
);

Thanks all for your responses. I used HtmlRenderer external dll (library) to achieve the same and found below code for the same.

Here is the code for this

public void ConvertHtmlToImage()
{
   Bitmap m_Bitmap = new Bitmap(400, 600);
   PointF point = new PointF(0, 0);
   SizeF maxSize = new System.Drawing.SizeF(500, 500);
   HtmlRenderer.HtmlRender.Render(Graphics.FromImage(m_Bitmap),
                                           "<html><body><p>This is some html code</p>"
                                           + "<p>This is another html line</p></body>",
                                            point, maxSize);

   m_Bitmap.Save(@"C:\Test.png", ImageFormat.Png);
}

The documents on fs.stat() says to use fs.access() if you are not going to manipulate the file. It did not give a justification, might be faster or less memeory use?

I use node for linear automation, so I thought I share the function I use to test for file existence.

var fs = require("fs");

function exists(path){
    //Remember file access time will slow your program.
    try{
        fs.accessSync(path);
    } catch (err){
        return false;
    }
    return true;
}

This is the NPM known Issue for windows that NPM is pretty much unusable under Windows. This is of course related to the path size limitations.

https://github.com/npm/npm/issues/5641

My main concern here is that there are no mention of these issues when installing node or npm via the website. Not being able to install prime packages makes npm fundamentally unusable for windows.

I wrote this function for both copying (copyFileSync) or moving (renameSync) files recursively between directories:

// Copy files
copyDirectoryRecursiveSync(sourceDir, targetDir);
// Move files
copyDirectoryRecursiveSync(sourceDir, targetDir, true);


function copyDirectoryRecursiveSync(source, target, move) {
    if (!fs.lstatSync(source).isDirectory())
        return;

    var operation = move ? fs.renameSync : fs.copyFileSync;
    fs.readdirSync(source).forEach(function (itemName) {
        var sourcePath = path.join(source, itemName);
        var targetPath = path.join(target, itemName);

        if (fs.lstatSync(sourcePath).isDirectory()) {
            fs.mkdirSync(targetPath);
            copyDirectoryRecursiveSync(sourcePath, targetDir);
        }
        else {
            operation(sourcePath, targetPath);
        }
    });
}

When you are in the Command, click Create to create a new parameter; call it project_name. Once you've created it, double click its name to add it to the command's text. You query should resemble:

SELECT Projecttname, ReleaseDate, TaskName
FROM DB_Table
WHERE Project_Name LIKE {?project_name} + '*'
AND ReleaseDate >= getdate() --assumes sql server

If desired, link the main report to the subreport on this ({?project_name}) field. If you don't establish a link between the main and subreport, CR will prompt you for the subreport's parameter.

In versions prior to 2008, a command's parameter was only allowed to be a scalar value.

Now with Java EE 7 you can find the resource more easily with

InputStream resource = getServletContext().getResourceAsStream("/WEB-INF/my.json");

https://docs.oracle.com/javaee/7/api/javax/servlet/GenericServlet.html#getServletContext--

Recently stumbled upon this issue, in my case I did a few things:

1. Make sure the namespaces are consistent in the Designer.cs file of the resx file

2. Make sure the default namespace of the Assembly(right click the project and choose Properties) is set the same to the namespace the resources file is in.

Once I did step 2, the exception went away.

If you want to call a different size for the button inline, you would probably do it like this:

<div class="button" style="width:60px;height:100px;">This is a button</div>

Or, a better way to have different sizes (say there will be 3 standard sizes for the button) would be to have classes just for size.

For example, you would call your button like this:

<div class="button small">This is a button</div>

And in your CSS

.button.small { width: 60px; height: 100px; }

and just create classes for each size you wish to have. That way you still have the perks of using a stylesheet in case say, you want to change the size of all the small buttons at once.

No, but they're fakeable using proxies and reflection:

  public static class TestClass {
      public String knockKnock() {
          return "who's there?";
      }
  }

  private final TestClass testInstance = new TestClass();

  @Test public void
  can_delegate_a_single_method_interface_to_an_instance() throws Exception {
      Delegator<TestClass, Callable<String>> knockKnockDelegator = Delegator.ofMethod("knockKnock")
                                                                   .of(TestClass.class)
                                                                   .to(Callable.class);
      Callable<String> callable = knockKnockDelegator.delegateTo(testInstance);
      assertThat(callable.call(), is("who's there?"));
  }

The nice thing about this idiom is that you can verify that the delegated-to method exists, and has the required signature, at the point where you create the delegator (although not at compile-time, unfortunately, although a FindBugs plug-in might help here), then use it safely to delegate to various instances.

See the karg code on github for more tests and implementation.

WITH NOCHECK is used as well when one has existing data in a table that doesn't conform to the constraint as defined and you don't want it to run afoul of the new constraint that you're implementing...

From the hive shell issue 'set system.sun.java.command' The hive-cli.jar version is the hive version.

<code>
hive> set system:sun.java.command;
system:sun.java.command=org.apache.hadoop.util.RunJar /opt/cloudera/parcels/CDH-4.2.2-1.cdh4.2.2.p0.10/bin/../lib/hive/lib/hive-cli-**0.10.0**-cdh**4.2.2**.jar org.apache.hadoop.hive.cli.CliDriver
hive> 
</code>

The above example shows Hive version 0.10.0 for CDH version 4.2.2

You can set left margins for li tags in percents and set the same negative left margin on parent:

ul {margin-left:-5%;}_x000D_
li {width:20%;margin-left:5%;float:left;}

<ul>_x000D_
  <li>A_x000D_
  <li>B_x000D_
  <li>C_x000D_
  <li>D_x000D_
</ul>

If none of the TargetDir or other macros point to the right place, use the ".." directory to go backwards up the folder hierarchy.

ie. Use $(SolutionDir)\..\.. to get your base directory.

For list of all macros, see here:

Seems to be working:

#content {
    /* or just insert a number with "px" if you're fighting CSS without lesscss.org :) */
    vertical-align: -@header_height + @content_height;

    /* only need it if your content is <div>,
     * if it is inline (e.g., <a>) will work without it */
    display: inline-block;
}

Using less makes solving CSS puzzles much more like coding than like... I just love CSS. It's a real pleasure when you can change the whole layout (without breaking it :) just by changing one parameter.

public static String getMacAddr() {
    try {
        List<NetworkInterface> all = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface nif : all) {
            if (!nif.getName().equalsIgnoreCase("wlan0")) continue;

            byte[] macBytes = nif.getHardwareAddress();
            if (macBytes == null) {
                return "";
            }

            StringBuilder res1 = new StringBuilder();
            for (byte b : macBytes) {
                res1.append(String.format("%02X:",b));
            }

            if (res1.length() > 0) {
                res1.deleteCharAt(res1.length() - 1);
            }
            return res1.toString();
        }
    } catch (Exception ex) {
    }
    return "02:00:00:00:00:00";
}

I also had issue with git PS1 slowness, although for a long time I was thinking it's a database size problem (big repository) and was trying various git gc tricks, and were looking for other reasons, just like you. However, in my case, the problem was this line:

function ps1_gitify
{
   status=$(git status 2>/dev/null )      # <--------------------
   if [[ $status =~ "fatal: Not a git repository" ]]
   then
       echo ""
   else
       echo "$(ps1_git_branch_name)  $(ps1_git_get_sha)"
  fi
}

Doing the git status for every command line status line was slow. Ouch. It was something I wrote by hand. I saw that was a problem when I tried the

export PS1='$'

like mentioned in one answer here. The command line was lightning fast.

Now I'm using this:

function we_are_in_git_work_tree
{
    git rev-parse --is-inside-work-tree &> /dev/null
}

function ps1_gitify
{
    if ! we_are_in_git_work_tree
    then
    ...

From the Stack Overflow post PS1 line with git current branch and colors and it works fine. Again have a fast Git command line.

Since rows already exist in the table, the ALTER statement is trying to insert NULL into the newly created column for all of the existing rows. You would have to add the column as allowing NULL, then fill the column with the values you want, and then set it to NOT NULL afterwards.

Here is a stripped down example, using as little HTML markup as possible.

The Basics

• The overlay is provided by the :before pseudo element on the .content container.

• No z-index is required, :before is naturally layered over the video element.

• The .content container is position: relative so that the position: absolute overlay is positioned in relation to it.

• The overlay is stretched to cover the entire .content div width with left / right / bottom and left set to 0.

• The width of the video is controlled by the width of its container with width: 100%

The Demo

.content {
  position: relative;
  width: 500px;
  margin: 0 auto;
  padding: 20px;
}
.content video {
  width: 100%;
  display: block;
}
.content:before {
  content: '';
  position: absolute;
  background: rgba(0, 0, 0, 0.5);
  border-radius: 5px;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
}

<div class="content">
  <video id="player" src="https://upload.wikimedia.org/wikipedia/commons/transcoded/1/18/Big_Buck_Bunny_Trailer_1080p.ogv/Big_Buck_Bunny_Trailer_1080p.ogv.360p.vp9.webm" autoplay loop muted></video>
</div>

To keep this question current it is worth highlighting that AssemblyInformationalVersion is used by NuGet and reflects the package version including any pre-release suffix.

For example an AssemblyVersion of 1.0.3.* packaged with the asp.net core dotnet-cli

dotnet pack --version-suffix ci-7 src/MyProject

Produces a package with version 1.0.3-ci-7 which you can inspect with reflection using:

CustomAttributeExtensions.GetCustomAttribute<AssemblyInformationalVersionAttribute>(asm);

You can have a recursive function with a parse function built within it.

Here how it works

// recursively loops through nested object and applys parse function_x000D_
function parseObjectProperties(obj, parse) {_x000D_
  for (var k in obj) {_x000D_
    if (typeof obj[k] === 'object' && obj[k] !== null) {_x000D_
      parseObjectProperties(obj[k], parse)_x000D_
    } else if (obj.hasOwnProperty(k)) {_x000D_
      parse(obj, k)_x000D_
    }_x000D_
  }_x000D_
}_x000D_
//**************_x000D_
_x000D_
_x000D_
// example_x000D_
var foo = {_x000D_
  bar:'a',_x000D_
  child:{_x000D_
    b: 'b',_x000D_
    grand:{_x000D_
      greatgrand: {_x000D_
        c:'c'_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
}_x000D_
_x000D_
_x000D_
// just console properties_x000D_
parseObjectProperties(foo, function(obj, prop) {_x000D_
  console.log(prop + ':' + obj[prop])_x000D_
})_x000D_
_x000D_
// add character a on every property_x000D_
parseObjectProperties(foo, function(obj, prop) {_x000D_
  obj[prop] += 'a'_x000D_
})_x000D_
console.log(foo)
