just to toss it out for posterity: it can sometimes be preferable to generate a random string using an initial character set string. This is useful if the string is supposed to be entered manually by a human; excluding 0, O, 1, and l can help reduce user error.

var alpha = "abcdefghijkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ23456789"

// generates a random string of fixed size
func srand(size int) string {
    buf := make([]byte, size)
    for i := 0; i < size; i++ {
        buf[i] = alpha[rand.Intn(len(alpha))]
    }
    return string(buf)
}

and I typically set the seed inside of an init() block. They're documented here: http://golang.org/doc/effective_go.html#init

Yes, there's str_to_date

mysql> select str_to_date("03/02/2009","%d/%m/%Y");
+--------------------------------------+
| str_to_date("03/02/2009","%d/%m/%Y") |
+--------------------------------------+
| 2009-02-03                           |

Big thanks to Lars Blumberg his answer for capturing groups and full matches with Swift 4, which helped me out a lot. I also made an addition to it for the people who do want an error.localizedDescription response when their regex is invalid:

extension String {
    func matchingStrings(regex: String) -> [[String]] {
        do {
            let regex = try NSRegularExpression(pattern: regex)
            let nsString = self as NSString
            let results  = regex.matches(in: self, options: [], range: NSMakeRange(0, nsString.length))
            return results.map { result in
                (0..<result.numberOfRanges).map {
                    result.range(at: $0).location != NSNotFound
                        ? nsString.substring(with: result.range(at: $0))
                        : ""
                }
            }
        } catch let error {
            print("invalid regex: \(error.localizedDescription)")
            return []
        }
    }
}

For me having the localizedDescription as error helped understand what went wrong with escaping, since it's displays which final regex swift tries to implement.

For Windows users

Use the original code as it's:

from selenium import webdriver
browser = webdriver.Firefox()
driver.get("https://www.google.com")

Then download the driver from: mozilla/geckodriver

Place it in a fixed path (permanently)... As an example, I put it in:

C:\Python35

Then go to the environment variables of the system. In the grid of "System variables" look for the Path variable and add:

;C:\Python35\geckodriver

geckodriver, not geckodriver.exe.

If you want to use the iframe's scrollbar and not the parent's use this:

document.body.style.overflow = 'hidden';

If you want to use the parent's scrollbar and not the iframe's then you need to use:

document.getElementById('your_iframes_id').scrolling = 'no';

or set the scrolling="no" attribute in your iframe's tag: <iframe src="some_url" scrolling="no">.

As Homebrew is my favorite for macOS although it is possible to have apt-get on macOS using Fink.

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

From:

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

If you are running the program with python, try running it with python3.

Java Date to int conversion:

public static final String DATE_FORMAT_INT = "yyyyMMdd";

public static String format(Date date, String format) {
    return isNull(date) ?  
    null : new SimpleDateFormat(format).format(date);
}

public static Integer getDateInt(Date date) {
    if (isNull(date)) {
        throw new IllegalArgumentException("Date must not be NULL");
    }

    return parseInt(format(date, DATE_FORMAT_INT));
}

The recommended approach in this case is to sort the data in the database, adding an ORDER BY at the end of the query that fetches the results, something like this:

SELECT temperature FROM temperatures ORDER BY temperature ASC;  -- ascending order
SELECT temperature FROM temperatures ORDER BY temperature DESC; -- descending order

If for some reason that is not an option, you can change the sorting order like this in Python:

templist = [25, 50, 100, 150, 200, 250, 300, 33]
sorted(templist, key=int)               # ascending order
> [25, 33, 50, 100, 150, 200, 250, 300]
sorted(templist, key=int, reverse=True) # descending order
> [300, 250, 200, 150, 100, 50, 33, 25]

As has been pointed in the comments, the int key (or float if values with decimals are being stored) is required for correctly sorting the data if the data received is of type string, but it'd be very strange to store temperature values as strings, if that is the case, go back and fix the problem at the root, and make sure that the temperatures being stored are numbers.

Here's a one-liner slim way for layering text on top of an input in jQuery using ES6 syntax.

$('.input-group > input').focus(e => $(e.currentTarget).parent().find('.placeholder').hide()).blur(e => { if (!$(e.currentTarget).val()) $(e.currentTarget).parent().find('.placeholder').show(); });

* {
  font-family: sans-serif;
}

.input-group {
  position: relative;
}

.input-group > input {
  width: 150px;
  padding: 10px 0px 10px 25px;
}

.input-group > .placeholder {
  position: absolute;
  top: 50%;
  left: 25px;
  transform: translateY(-50%);
  color: #929292;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="input-group">
  <span class="placeholder">Username</span>
  <input>
</div>

It appears that SQL Server 2008 R2 can be downloaded with or without the management tools. I honestly have NO IDEA why someone would not want the management tools. But either way, the options are here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

and the one for 64 bit WITH the management tools (management studio) is here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

From the first link I presented, the 3rd and 4th include the management studio for 32 and 64 bit respectively.

UPDATE - Even less wordy version

INSERT INTO tableName (col1, col2, col3, col4, col5) 
VALUES ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5')

The following also works for DB2 and is slightly less wordy

INSERT INTO tableName (col1, col2, col3, col4, col5) 
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5')

Both your queries are correct and should give you the right answer.

I would suggest the following query to troubleshoot your problem.

SELECT DISTINCT a,b,c,d,count(*) Count FROM my_table GROUP BY a,b,c,d
order by count(*) desc

That is add count(*) field. This will give you idea how many rows were eliminated using the group command.

You can also simply use this:

.bg_rgba {
  background: linear-gradient(0deg, rgba(255, 255, 255, 0.9), rgba(255, 255, 255, 0.9)), url('https://picsum.photos/200');
  width: 200px;
  height: 200px;
  border: 1px solid black;
}

<div class='bg_rgba'></div>

You can change the opacity of the color to your preference.

It exists now in the statsmodels package:

http://statsmodels.sourceforge.net/devel/generated/statsmodels.graphics.gofplots.qqplot.html

I would like to suggest you this amazing class. This worked very well for me.

They are not null if you don't initialize the struct.

Snapshot s; // receives no initialization
Snapshot s = {}; // value initializes all members

The second will make all members zero, the first leaves them at unspecified values. Note that it is recursive:

struct Parent { Snapshot s; };
Parent p; // receives no initialization
Parent p = {}; // value initializes all members

The second will make p.s.{x,y} zero. You cannot use these aggregate initializer lists if you've got constructors in your struct. If that is the case, you will have to add proper initalization to those constructors

struct Snapshot {
    int x;
    double y;
    Snapshot():x(0),y(0) { }
    // other ctors / functions...
};

Will initialize both x and y to 0. Note that you can use x(), y() to initialize them disregarding of their type: That's then value initialization, and usually yields a proper initial value (0 for int, 0.0 for double, calling the default constructor for user defined types that have user declared constructors, ...). This is important especially if your struct is a template.

I think it is a problem(aka. bug) with the API you are using. JSONArray implements Collection (the json.org implementation from which this API is derived does not have JSONArray implement Collection). And JSONObject has an overloaded put() method which takes a Collection and wraps it in a JSONArray (thus causing the problem). I think you need to force the other JSONObject.put() method to be used:

    jsonObject.put("aoColumnDefs",(Object)arr);

You should file a bug with the vendor, pretty sure their JSONObject.put(String,Collection) method is broken.

The connection string is not in AppSettings.

What you're looking for is in:

System.Configuration.ConfigurationManager.ConnectionStrings["MyDB"]...

Use command

google-chrome-stable

We can also use command

google-chrome

To open terminal but in my case when I make an interrupt ctrl + c then it get closed so I would recommend to use google-chrome-stable instead of google-chrome

Hmm... I think you can use e.clipboardData to catch the data being pasted. If it doesn't pan out, have a look here.

$(this).live("paste", function(e) {
    alert(e.clipboardData); // [object Clipboard]
});

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

You can use sum() with a generator expression:

with open('data.txt') as f:
    print sum(1 for _ in f)

Note that you cannot use len(f), since f is an iterator. _ is a special variable name for throwaway variables, see What is the purpose of the single underscore "_" variable in Python?.

You can use len(f.readlines()), but this will create an additional list in memory, which won't even work on huge files that don't fit in memory.

No you can't use bind variables that way. In your second example :into_bind in v_query_str is just a placeholder for value of variable v_num_of_employees. Your select into statement will turn into something like:

SELECT COUNT(*) INTO  FROM emp_...

because the value of v_num_of_employees is null at EXECUTE IMMEDIATE.

Your first example presents the correct way to bind the return value to a variable.

Edit

The original poster has edited the second code block that I'm referring in my answer to use OUT parameter mode for v_num_of_employees instead of the default IN mode. This modification makes the both examples functionally equivalent.

For use key/value pair in json use an object and don't use array

Find name/value in array is hard but in object is easy

Ex:

var exObj = {_x000D_
  "mainData": {_x000D_
    "slide0001.html": "Looking Ahead",_x000D_
    "slide0008.html": "Forecast",_x000D_
    "slide0021.html": "Summary",_x000D_
    // another THOUSANDS KEY VALUE PAIRS_x000D_
    // ..._x000D_
  },_x000D_
  "otherdata" : { "one": "1", "two": "2", "three": "3" }_x000D_
};_x000D_
var mainData = exObj.mainData;_x000D_
// for use:_x000D_
Object.keys(mainData).forEach(function(n,i){_x000D_
  var v = mainData[n];_x000D_
  console.log('name' + i + ': ' + n + ', value' + i + ': ' + v);_x000D_
});_x000D_
_x000D_
// and string length is minimum_x000D_
console.log(JSON.stringify(exObj));_x000D_
console.log(JSON.stringify(exObj).length);

Try this:

ssh your_user@your_server svnserve --version

import os
for subdir, dirs, files in os.walk('./'):
    for file in files:
      do some stuff
      print file

You can improve this code with del dirs[:]which will be like following .

import os
for subdir, dirs, files in os.walk('./'):
    del dirs[:]
    for file in files:
      do some stuff
      print file

Or even better if you could point os.walk with current working directory .

import os
cwd = os.getcwd()
for subdir, dirs, files in os.walk(cwd, topdown=True):
    del dirs[:]  # remove the sub directories.
    for file in files:
      do some stuff
      print file

Use String#trim() method or String allRemoved = myString.replaceAll("^\\s+|\\s+$", "") for trim both the end.

For left trim:

String leftRemoved = myString.replaceAll("^\\s+", "");

For right trim:

String rightRemoved = myString.replaceAll("\\s+$", "");

You may use this:

Intent intent = new Intent(getApplicationContext(), ClassName.class);

If you are not using ng-bind, instead something like this:

<div>
  Hello, {{user.name}}
</div>

you might see the actual Hello, {{user.name}} for a second before user.name is resolved (before the data is loaded)

You could do something like this

<div>
  Hello, <span ng-bind="user.name"></span>
</div>

if that's an issue for you.

Another solution is to use ng-cloak.

I have worked a bit on a simple algorithm to compare contents of two objects and return an intelligible list of difference. Thought I would share. It borrows some ideas for jQuery, namely the map function implementation and the object and array type checking.

It returns a list of "diff objects", which are arrays with the diff info. It's very simple.

Here it is:

// compare contents of two objects and return a list of differences
// returns an array where each element is also an array in the form:
// [accessor, diffType, leftValue, rightValue ]
//
// diffType is one of the following:
//   value: when primitive values at that index are different
//   undefined: when values in that index exist in one object but don't in 
//              another; one of the values is always undefined
//   null: when a value in that index is null or undefined; values are
//         expressed as boolean values, indicated wheter they were nulls
//   type: when values in that index are of different types; values are 
//         expressed as types
//   length: when arrays in that index are of different length; values are
//           the lengths of the arrays
//

function DiffObjects(o1, o2) {
    // choose a map() impl.
    // you may use $.map from jQuery if you wish
    var map = Array.prototype.map?
        function(a) { return Array.prototype.map.apply(a, Array.prototype.slice.call(arguments, 1)); } :
        function(a, f) { 
            var ret = new Array(a.length), value;
            for ( var i = 0, length = a.length; i < length; i++ ) 
                ret[i] = f(a[i], i);
            return ret.concat();
        };

    // shorthand for push impl.
    var push = Array.prototype.push;

    // check for null/undefined values
    if ((o1 == null) || (o2 == null)) {
        if (o1 != o2)
            return [["", "null", o1!=null, o2!=null]];

        return undefined; // both null
    }
    // compare types
    if ((o1.constructor != o2.constructor) ||
        (typeof o1 != typeof o2)) {
        return [["", "type", Object.prototype.toString.call(o1), Object.prototype.toString.call(o2) ]]; // different type

        if (o1.length != o2.length) { 
            return [["", "length", o1.length, o2.length]]; // different length
        }
        var diff =[];
        for (var i=0; i<o1.length; i++) {
            // per element nested diff
            var innerDiff = DiffObjects(o1[i], o2[i]);
            if (innerDiff) { // o1[i] != o2[i]
                // merge diff array into parent's while including parent object name ([i])
                push.apply(diff, map(innerDiff, function(o, j) { o[0]="[" + i + "]" + o[0]; return o; }));
            }
        }
        // if any differences were found, return them
        if (diff.length)
            return diff;
        // return nothing if arrays equal
        return undefined;
    }

    // compare object trees
    if (Object.prototype.toString.call(o1) == "[object Object]") {
        var diff =[];
        // check all props in o1
        for (var prop in o1) {
            // the double check in o1 is because in V8 objects remember keys set to undefined 
            if ((typeof o2[prop] == "undefined") && (typeof o1[prop] != "undefined")) {
                // prop exists in o1 but not in o2
                diff.push(["[" + prop + "]", "undefined", o1[prop], undefined]); // prop exists in o1 but not in o2

            }
            else {
                // per element nested diff
                var innerDiff = DiffObjects(o1[prop], o2[prop]);
                if (innerDiff) { // o1[prop] != o2[prop]
                    // merge diff array into parent's while including parent object name ([prop])
                    push.apply(diff, map(innerDiff, function(o, j) { o[0]="[" + prop + "]" + o[0]; return o; }));
                }

            }
        }
        for (var prop in o2) {
            // the double check in o2 is because in V8 objects remember keys set to undefined 
            if ((typeof o1[prop] == "undefined") && (typeof o2[prop] != "undefined")) {
                // prop exists in o2 but not in o1
                diff.push(["[" + prop + "]", "undefined", undefined, o2[prop]]); // prop exists in o2 but not in o1

            }
        }
        // if any differences were found, return them
        if (diff.length)
            return diff;
        // return nothing if objects equal
        return undefined;
    }
    // if same type and not null or objects or arrays
    // perform primitive value comparison
    if (o1 != o2)
        return [["", "value", o1, o2]];

    // return nothing if values are equal
    return undefined;
}

Assuming that the order is the same in both objects, just stringify them both and compare!

JSON.stringify(obj1) == JSON.stringify(obj2);

Also you can bind to the public static members of the enum directly by using reflection:

typeof(Suit).GetMembers(BindingFlags.Public | BindingFlags.Static)
    .ToList().ForEach(x => DoSomething(x.Name));

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

The use of the deprecated new Buffer() constructor (i.E. as used by Yarn) can cause deprecation warnings. Therefore one should NOT use the deprecated/unsafe Buffer constructor.

According to the deprecation warning new Buffer() should be replaced with one of:

• Buffer.alloc()
• Buffer.allocUnsafe() or
• Buffer.from()

Another option in order to avoid this issue would be using the safe-buffer package instead.

You can also try (when using yarn..):

yarn global add yarn

as mentioned here: Link

Another suggestion from the comments (thx to gkiely): self-update

Note: self-update is not available. See policies for enforcing versions within a project

In order to update your version of Yarn, run

curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

Can you place the #ulId in the document prior to the ajax load (with css display: none;), or wrap it in a containing div (with css display: none;), then just load the inner html during ajax page load, that way the scroll event will be linked to the div that is already there prior to the ajax?

Then you can use:

$('#ulId').on('scroll',function(){ console.log('Event Fired'); })

obviously replacing ulId with whatever the actual id of the scrollable div is.

Then set css display: block; on the #ulId (or containing div) upon load?

The following line is wrong in your version:

WHILE (@i <= (SELECT MAX(idx) FROM @Practitioner))

(Missing the @)

Might be an idea to change your naming convention so that the tables are more different.

I know this isn't the best way to do it, but right click the button in question, events, key, key typed. This is a simple way to do it, but reacts to any key

http://code.google.com/p/py2c/ looks like a possibility - they also mention on their site: Cython, Shedskin and RPython and confirm that they are converting Python code to pure C/C++ which is much faster than C/C++ riddled with Python API calls. Note: I haven’t tried it but I am going to..

console.log(obj2.names());
// prints: ["Jim", "Ralph"]

obj1.add("Bart");
console.log(obj2.names());
// prints: ["Jim", "Ralph", "Bart"]

Got better solution:

    stop: function( event, ui ) {
        $('#element').height(ui.originalSize.height);
    }
});

I was able to use the answer outlined here: Export to CSV using jQuery and html and added in a modification to make it work in IE and another modification mentioned in the comments to grab the thead from the table.

function exportTableToCSV($table, filename) {

    var $rows = $table.find('tr:has(td),tr:has(th)'),

        // Temporary delimiter characters unlikely to be typed by keyboard
        // This is to avoid accidentally splitting the actual contents
        tmpColDelim = String.fromCharCode(11), // vertical tab character
        tmpRowDelim = String.fromCharCode(0), // null character

        // actual delimiter characters for CSV format
        colDelim = '","',
        rowDelim = '"\r\n"',

        // Grab text from table into CSV formatted string
        csv = '"' + $rows.map(function (i, row) {
            var $row = $(row), $cols = $row.find('td,th');

            return $cols.map(function (j, col) {
                var $col = $(col), text = $col.text();

                return text.replace(/"/g, '""'); // escape double quotes

            }).get().join(tmpColDelim);

        }).get().join(tmpRowDelim)
            .split(tmpRowDelim).join(rowDelim)
            .split(tmpColDelim).join(colDelim) + '"',



        // Data URI
        csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);

        console.log(csv);

        if (window.navigator.msSaveBlob) { // IE 10+
            //alert('IE' + csv);
            window.navigator.msSaveOrOpenBlob(new Blob([csv], {type: "text/plain;charset=utf-8;"}), "csvname.csv")
        } 
        else {
            $(this).attr({ 'download': filename, 'href': csvData, 'target': '_blank' }); 
        }
}

// This must be a hyperlink
$("#xx").on('click', function (event) {

    exportTableToCSV.apply(this, [$('#projectSpreadsheet'), 'export.csv']);

    // IF CSV, don't do event.preventDefault() or return false
    // We actually need this to be a typical hyperlink

This question is several years old, but I stumbled upon it, which means maybe others will.

The readr library / package has some nice features to it. One of them is a nice way to interpret "messy" columns, like these.

library(readr)
read_csv("numbers\n800\n\"1,800\"\n\"3500\"\n6.5",
          col_types = list(col_numeric())
        )

This yields

Source: local data frame [4 x 1]

  numbers
    (dbl)
1   800.0
2  1800.0
3  3500.0
4     6.5

An important point when reading in files: you either have to pre-process, like the comment above regarding sed, or you have to process while reading. Often, if you try to fix things after the fact, there are some dangerous assumptions made that are hard to find. (Which is why flat files are so evil in the first place.)

For instance, if I had not flagged the col_types, I would have gotten this:

> read_csv("numbers\n800\n\"1,800\"\n\"3500\"\n6.5")
Source: local data frame [4 x 1]

  numbers
    (chr)
1     800
2   1,800
3    3500
4     6.5

(Notice that it is now a chr (character) instead of a numeric.)

Or, more dangerously, if it were long enough and most of the early elements did not contain commas:

> set.seed(1)
> tmp <- as.character(sample(c(1:10), 100, replace=TRUE))
> tmp <- c(tmp, "1,003")
> tmp <- paste(tmp, collapse="\"\n\"")

(such that the last few elements look like:)

\"5\"\n\"9\"\n\"7\"\n\"1,003"

Then you'll find trouble reading that comma at all!

> tail(read_csv(tmp))
Source: local data frame [6 x 1]

     3"
  (dbl)
1 8.000
2 5.000
3 5.000
4 9.000

6 1.003

For pushing a single tag: git push <reponame> <tagname>

For instance, git push production 1.0.0. Tags are not bound to branches, they are bound to commits.

When you want to have the tag's content in the master branch, do that locally on your machine. I would assume that you continued developing in your local master branch. Then just a git push origin master should suffice.

your programs syntax, or for that matter many other things such as natural languages can be parsed using binary tree (though not necessarily).

I have just found a PHP function "strip_tags()" and its working in my case.

I tried to convert the following HTML :

After applying strip_tags() function, I have got the following output :

Here are some common format strings

With existing Hamcrest libraries (as of v.2.0.0.0) you are forced to use Collection.toArray() method on your Collection in order to use containsInAnyOrder Matcher. Far nicer would be to add this as a separate method to org.hamcrest.Matchers:

public static <T> org.hamcrest.Matcher<java.lang.Iterable<? extends T>> containsInAnyOrder(Collection<T> items) {
    return org.hamcrest.collection.IsIterableContainingInAnyOrder.<T>containsInAnyOrder((T[]) items.toArray());
}

Actually I ended up adding this method to my custom test library and use it to increase readability of my test cases (due to less verbosity).

You must use it.

The practice of using a semicolon to terminate statements is standard and in fact is a requirement in several other database platforms. SQL Server requires the semicolon only in particular cases—but in cases where a semicolon is not required, using one doesn’t cause problems. I strongly recommend that you adopt the practice of terminating all statements with a semicolon. Not only will doing this improve the readability of your code, but in some cases it can save you some grief. (When a semicolon is required and is not specified, the error message SQL Server produces is not always very clear.)

And most important:

The SQL Server documentation indicates that not terminating T-SQL statements with a semicolon is a deprecated feature. This means that the long-term goal is to enforce use of the semicolon in a future version of the product. That’s one more reason to get into the habit of terminating all of your statements, even where it’s currently not required.

Source: Microsoft SQL Server 2012 T-SQL Fundamentals by Itzik Ben-Gan.

An example of why you always must use ; are the following two queries (copied from this post):

BEGIN TRY
    BEGIN TRAN
    SELECT 1/0 AS CauseAnException
    COMMIT
END TRY
BEGIN CATCH
    SELECT ERROR_MESSAGE()
    THROW
END CATCH

BEGIN TRY
    BEGIN TRAN
    SELECT 1/0 AS CauseAnException;
    COMMIT
END TRY
BEGIN CATCH
    SELECT ERROR_MESSAGE();
    THROW
END CATCH

To treat both , and . as decimal point you must not only replace one with the other, but also make sure the Culture used parsing interprets it as a decimal point.

text = text.Replace(',', '.');
return double.TryParse(text, NumberStyles.Any, CultureInfo.InvariantCulture, out value);

The given solution did not work for me, however a similar version did...

This is with a cloned repository, hence the submodule git repos are contained in the top repositories .git dir. All cations are from the top repository:

1. Edit .gitmodules and change the "path =" setting for the submodule in question. (No need to change the label, nor to add this file to index.)

2. Edit .git/modules/name/config and change the "worktree =" setting for the submodule in question

3. run:

   mv submodule newpath/submodule
   git add -u
   git add newpath/submodule
   

I wonder if it makes a difference if the repositories are atomic, or relative submodules, in my case it was relative (submodule/.git is a ref back to topproject/.git/modules/submodule)

Besides using the IN query, you have two options to do so as in an IN query there is a risk of an SQL injection vulnerability. You can use looping to get the exact data you want or you can use the query with OR case

1. SELECT *
      FROM galleries WHERE id=1 or id=2 or id=5;


2. $ids = array(1, 2, 5);
   foreach ($ids as $id) {
      $data[] = SELECT *
                    FROM galleries WHERE id= $id;
   }

To do this, stop the click on the child using .stopPropagation:

$(".example").click(function(){
  $(this).fadeOut("fast");
}).children().click(function(e) {
  return false;
});

This will stop the child clicks from bubbling up past their level so the parent won't receive the click.

.not() is used a bit differently, it filters elements out of your selector, for example:

<div class="bob" id="myID"></div>
<div class="bob"></div>

$(".bob").not("#myID"); //removes the element with myID

For clicking, your problem is that the click on a child bubbles up to the parent, not that you've inadvertently attached a click handler to the child.

This will do the trick:

Everyone in these answers has overlooked true access control / authorization.

If for instance your REST APIs / web services are about POSTing / GETing medical records, you may want to define access control policie about who can access the data and under which circumstances. For instance:

• doctors can GET the medical record of a patient they have a care relationship with
• no one can POST medical data outside practice hours (e.g. 9 to 5)
• end-users can GET medical records they own or medical records of patients for whom they are the guardian
• nurses can UPDATE the medical record of a patient that belongs to the same unit as the nurse.

In order to define and implement those fine-grained authorizations, you will need to use an attribute-based access control language called XACML, the eXtensible Access Control Markup Language.

The other standards here are for the following:

• OAuth: id. federation and delegation of authorization e.g. letting a service act on my behalf on another service (Facebook can post to my Twitter)
• SAML: identity federation / web SSO. SAML is very much about who the user is.
• WS-Security / WS-* standards: these focus on the communication between SOAP services. They are specific to the application-level messaging format (SOAP) and they deal with aspects of messaging e.g. reliability, security, confidentiality, integrity, atomicity, eventing... None cover access control and all are specific to SOAP.

XACML is technology-agnostic. It can be applied to java apps, .NET, Python, Ruby... web services, REST APIs, and more.

The following are interesting resources:

• the OASIS XACML website
• the NIST ABAC standard

The better solutions, when possible are:

• Replicate your data (using log-replication) to a reporting database.
• Use SAN snapshots and mount a consistent version of the DB
• Use a database which has a better fundamental transaction isolation level

The SNAPSHOT transaction isolation level was created because MS was losing sales to Oracle. Oracle uses undo/redo logs to avoid this problem. Postgres uses MVCC. In the future MS's Heckaton will use MVCC, but that's years away from being production ready.

Another regex example you can try using:

var mydate = json.date
var date = new Date(parseInt(mydate.replace(/\/Date\((-?\d+)\)\//, '$1');
mydate = date.getMonth() + 1 + '/' + date.getDate() + '/' + date.getFullYear();

date.getMonth() returns an integer 0 - 11 so we must add 1 to get the right month number wise

You can use a cast to char to see the date results

 select to_char(to_date('17-MAR-17 06.04.54','dd-MON-yy hh24:mi:ss'), 'mm/dd/yyyy hh24:mi:ss') from dual;

Someone has mentioned that if you are using terminal and your current directory is inside the path which you want to unmount, you will get the error.
As a complementary, in this case, your lsof | grep path-to-be-unmounted must have below output:

bash ... path-to-be-unmounted

There will be of course some rounding errors, so this is not perfect, but this is what I use generally for applications, which don't require high precision. If you wanted to make this more accurate, you could add an extra argument to specify how to handle rounding errors. Perhaps passing a rounding function might make this extensible and allow the programmer to specify how to handle rounding errors.

arange = lambda start, stop, step: [i + step * i for i in range(int((stop - start) / step))]

If I write:

arange(0, 1, 0.1)

It will output:

[0.0, 0.1, 0.2, 0.30000000000000004, 0.4, 0.5, 0.6000000000000001, 0.7000000000000001, 0.8, 0.9]

Try:

gradle assemble

To list all available tasks for your project, try:

gradle tasks

UPDATE:

This may not seem the most correct answer at first, but read carefully gradle tasks output or docs.

-----------
assemble - Assembles the outputs of this project.
build - Assembles and tests this project.

On Windows 8.1 I had to run cmd.exe as administrator (even though I was logged in as admin). Otherwise I got an error when trying to execute: httpd.exe -k uninstall

Error: C:\Program Files\Apache\bin>(OS 5)Access is denied. : AH00373: Apache2.4: OpenS ervice failed

Another option is:

filter1 = df.index.get_level_values('A') == 1
filter2 = df.index.get_level_values('B') == 4

df.iloc[filter1 & filter2]
Out[11]:
     0
A B
1 4  1

Say A:A contains the post codes, you could add a B column and put a 1 in each cell. In C1, put =SUMIF(A:A, A1, B:B) and Drag it down your sheet. That would give you the first desired result listed in your question.

EDIT: As Corey pointed out, you can just use COUNTIF(A:A, A1). As I mentioned in the comments you can copy paste special the row with formulas to hard code the counts, the select column A and click remove duplicates (entire row) to get your ideal result.

STEP 1

Go to properties of your project ( with Alt+Enter or righ-click )

STEP 2

check on Apache Tomcat v7.0 under Targeted Runtime and it works.

Like a lot of functions, this one can be used in many different ways to solve many different problems, I think of it as yet another tool in our toolbelts.

So far, the discussion has focused heavily on simply hiding an ID, but that is only one value, why not use it for lots of values! That is what I am doing, I use it to load up the values in a class only one view at a time, because html.beginform creates a new object and if your model object for that view already had some values passed to it, those values will be lost unless you provide a reference to those values in the beginform.

To see a great motivation for the html.hiddenfor, I recommend you see Passing data from a View to a Controller in .NET MVC - "@model" not highlighting

If you are looking to avoid multiple code lines to save space, maybe this syntax could be useful:

        java.util.ArrayList lisFieldNames = new ArrayList() {
            {
                add("value1"); 
                add("value2");
            }
        };

Removing new lines, you can show it compressed as:

        java.util.ArrayList lisFieldNames = new ArrayList() {
            {
                add("value1"); add("value2"); (...);
            }
        };

With GCC 4.1.2, to print the whole of a std::vector<int> called myVector, do the following:

print *(myVector._M_impl._M_start)@myVector.size()

To print only the first N elements, do:

print *(myVector._M_impl._M_start)@N

Explanation

This is probably heavily dependent on your compiler version, but for GCC 4.1.2, the pointer to the internal array is:

myVector._M_impl._M_start 

And the GDB command to print N elements of an array starting at pointer P is:

print P@N

Or, in a short form (for a standard .gdbinit):

p P@N

For those still having issues with Renderscript support library on x86 chipsets, please have a look at this post by the creator of the library. It looks like the fix he prepared didn't make it somehow to the Build Tools v20.0.0, so he provides the files to fix it manually and a brief explanation of how to do it.

In python: help(my_list.append) for example, will give you the docstring of the function.

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

Using the same center in the view and subview is the simplest way of doing it. You can do something like this,

UIView *innerView = ....;
innerView.view.center = self.view.center;
[self.view addSubView:innerView];

You can also harness the __new__ method to your advantage. You just forgot something. The __new__ method always returns the new object so you must return its superclass' new method. Do as follows.

class F:
    def __new__(cls):
        if cls is F:
            raise TypeError("Cannot create an instance of abstract class '{}'".format(cls.__name__))
        return super().__new__(cls)

When using the new method, you have to return the object, not the None keyword. That's all you missed.

Just throwing another solution in the mix...

Try jq, a lightweight and flexible command-line JSON processor:

jq length /tmp/test.json

Prints the length of the array of objects.

There are only 4 specific atrributes:

1. value - Value is the default value of the input box when a page is first loaded. This is a common attribute for element regardless which type you are using.
2. min - Obviously, the minimum value you of the number. I should have specified minimum value to 0 for my demo up there as a negative number doesn't make sense for number of movie watched in a week.
3. max - Apprently, this represents the biggest number of the number input.
4. step - Step scale factor, default value is 1 if this attribute is not specified.

So you cannot control length of what user type by keyword. But the implementation of browsers may change.

Here is the Swift 3 answer for anyone looking since Swift 3 does not accept "Make".

Whilst I recommend hyphens, I shall also postulate an answer that isn't on your list:

Nothing At All

• My company's API has URIs like /quotationrequests/, /purchaseorders/ and so on.
• Despite you saying it was an intranet app, you listed SEO as a benefit. Google does match the pattern /foobar/ in a URL for a query of ?q=foo+bar
• I really hope you do not consider executing a PHP call to any arbitrary string the user passes in to the address bar, as @ServAce85 suggests!

you can use flex box for it.. this will solve your problem

.image-parent 
{
     height:33px; 
     display:flex; 
}

If I understand your question correctly:

for elem in doc.findall('timeSeries/values/value'):
    print elem.get('dateTime'), elem.text

or if you prefer (and if there is only one occurrence of timeSeries/values:

values = doc.find('timeSeries/values')
for value in values:
    print value.get('dateTime'), elem.text

The findall() method returns a list of all matching elements, whereas find() returns only the first matching element. The first example loops over all the found elements, the second loops over the child elements of the values element, in this case leading to the same result.

I don't see where the problem with not finding timeSeries comes from however. Maybe you just forgot the getroot() call? (note that you don't really need it because you can work from the elementtree itself too, if you change the path expression to for example /timeSeriesResponse/timeSeries/values or //timeSeries/values)

When you have an assignment operator in a statement, the LHS of the operator must be something the language calls an lvalue. If the LHS of the operator does not evaluate to an lvalue, the value from the RHS cannot be assigned to the LHS.

You cannot use:

10 = 20;

since 10 does not evaluate to an lvalue.

You can use:

int i;
i = 20;

since i does evaluate to an lvalue.

You cannot use:

int i;
i + 1 = 20;

since i + 1 does not evaluate to an lvalue.

In your case, p + 1 does not evaluate to an lavalue. Hence, you cannot use

p + 1 = p;

Try this code, it works for me.

public class Third extends ListActivity {
private ArrayAdapter<String> adapter;
private List<String> liste;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_third);
     String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2" };
     liste = new ArrayList<String>();
     Collections.addAll(liste, values);
     adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, liste);
     setListAdapter(adapter);
}
 @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
     liste.remove(position);
     adapter.notifyDataSetChanged();
  }
}

Not completely clear what you mean. Perhaps:

<script type="text/javascript"> 
$(document).ready(function() {
  $("a").click(function() {
    var params = {};
    params['pageNo'] = $(this).text();
    params['sortBy'] = $("#sortBy").val();
    $("#results").load( "jquery-routing.php", params );
    return false;
  });
}); 
</script>

I have managed to get pycrypto to compile by using MinGW32 and MSYS. This presumes that you have pip or easy_install installed.

Here's how I did it:

1) Install MinGW32. For the sake of this explanation, let's assume it's installed in C:\MinGW. When using the installer, which I recommend, select the C++ compiler. MSYS should install with MinGW

2) Add c:\mingw\bin,c:\mingw\mingw32\bin,C:\MinGW\msys\1.0, c:\mingw\msys\1.0\bin and c:\mingw\msys\1.0\sbin to your %PATH%. If you aren't familiar, this article is very helpful.

3) From the search bar, run msys and the MSYS terminal will open. For those familiar with Cygwin, it works in a similar fashion.

4) From within the MSYS terminal pip install pycrypto should run without error after this.

In Python 3.6+ you could use Variable Annotations for this:

https://www.python.org/dev/peps/pep-0526/#abstract

PEP 484 introduced type hints, a.k.a. type annotations. While its main focus was function annotations, it also introduced the notion of type comments to annotate variables:

# 'captain' is a string (Note: initial value is a problem)
captain = ...  # type: str

PEP 526 aims at adding syntax to Python for annotating the types of variables (including class variables and instance variables), instead of expressing them through comments:

captain: str  # Note: no initial value!

It seems to be more directly in line with what you were asking "Is it possible only to declare a variable without assigning any value in Python?"

You can change the eclipse tomcat server configuration. Open the server view, double click on you server to open server configuration. Then click to activate "Publish module contents to separate XML files". Finally, restart your server, the message must disappear.

I wanted to do the same thing. The best I could find was @MicTech's solution. However, as pointed out by @MotoWilliams this does not survive any updates made by Git to the .gitconfig file which replaces the link with a new file containing only the new settings.

I solved this by writing the following PowerShell script and running it in my profile startup script. Each time it is run it copies any settings that have been added to the user's .gitconfig to the global one and then replaces all the text in the .gitconfig file with and [include] header that imports the global file.

I keep the global .gitconfig file in a repo along with a lot of other global scripts and tools. All I have to do is remember to check in any changes that the script appends to my global file.

This seems to work pretty transparently for me. Hope it helps!

Why not just:

$('#b').click(function () {
    var val = $(this).val(); 
})

Or if you don't click it (and I guess you won't) and you will use submit button, you can use prev() function either.

Custom filter is more appropriate, then you can use it anywhere in the project

js file

var myApp = angular.module('myApp',[]);

myApp.filter('utcdate', ['$filter','$locale', function($filter, $locale){

    return function (input, format) {
        if (!angular.isDefined(format)) {
            format = $locale['DATETIME_FORMATS']['medium'];
        }

        var date = new Date(input);
        var d = new Date()
        var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),  date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
        return $filter('date')(_utc, format)
    };

 }]);

in template

<p>This will convert UTC time to local time<p>
<span>{{dateTimeInUTC | utcdate :'MMM d, y h:mm:ss a'}}</span>

After running the repair I was able to start the mongod proccessor but as root, which meant that service mongod start would not work. To repair this issue, I needed to make sure that all the files inside the database folder were owned and grouped to mongod. I did this by the following:

1. Check the file permissions inside your database folder
   1. note you need to be in your dbpath folder mine was /var/lib/mongo I went to cd /var/lib
   2. I ran ls -l mongo
2. This showed me that databases were owned by root, which is wrong. I ran the following to fix this: chown -R mongod:mongod mongo. This changed the owner and group of every file in the folder to mongod. (If using the mongodb package, chown -R mongodb:mongodb mongodb)

I hope this helps someone else in the future.

(No space inside your website)

Most modern desktop browsers such as Chrome, Mozilla and Internet Explorer support images encoded as data URL. But there are problems displaying data URLs in some mobile browsers: Android Stock Browser and Dolphin Browser won't display embedded JPEGs.

I reccomend you to use the following tools for online base64 encoding/decoding:

• Encode to Base64 format

• Decode from Base64 format

Check the "Format as Data URL" option to format as a Data URL.

The previous accepted solution is not working any longer.

I ended up coding a simple function which wraps the range into a styled container adding the bar that is needed before the cursor. I wrote this example where easy to see the two colors 'blue' and 'orange' set in the css, so they can be quickly modified.

I've read some good answers here; however, there are some minor mistakes. Some have answered that the Message Length field in the UDP header is a max of 65535 (0xFFFF); this is technically true. Some have answered that the actual maximum is (65535 - IPHL - UDPHL = 65507). The mistake, is that the Message Length field in the UDP Header includes all payload (Layers 5-7), plus the length of the UDP Header (8 Bytes). What this means is that if the message length field is 200 Bytes (0x00C8), the payload is actually 192 Bytes (0x00C0).

What is hard and fast is that the maximum size of an IP datagram is 65535 Bytes. This number is arrived at the sum total of the L3 and L4 headers, plus the Layers 5-7 payload. IP Header + UDP Header + Layers 5-7 = 65535 (Max).

The most correct answer for what is the maximum size of a UDP datagam is 65515 Bytes (0xFFEB), as a UDP datagram includes the UDP header. The most correct answer for what is the maximum size of a UDP payload is 65507 Bytes, as a UDP Payload does not include the UDP header.

I would much rather go the route of the wil's answer or Vinayak Dornala, unfortunately they effected my performance far to much. I went for a HACKY solution of implicit casting:

for (Row row : sheet){
String strValue = (row.getCell(numericColumn)+""); // hack
...

I don't suggest you do this, for my situation it worked because of the nature of how the system worked and I had a reliable file source.

Footnote: numericColumn Is an int which is generated from reading the header of the file processed.

Yeah, it is quite vague.

You should use it whenever for readers of the documentation of your method it may be useful to also look at some other method. If the documentation of your methodA says "Works like methodB but ...", then you surely should put a link. An alternative to @see would be the inline {@link ...} tag:

/**
 * ...
 * Works like {@link #methodB}, but ...
 */

When the fact that methodA calls methodB is an implementation detail and there is no real relation from the outside, you don't need a link here.

A generic function for occurrences of strings:

public int getNumberOfOccurencies(String inputString, String checkString)
{
    if (checkString.Length > inputString.Length || checkString.Equals("")) { return 0; }
    int lengthDifference = inputString.Length - checkString.Length;
    int occurencies = 0;
    for (int i = 0; i < lengthDifference; i++) {
        if (inputString.Substring(i, checkString.Length).Equals(checkString)) { occurencies++; i += checkString.Length - 1; } }
    return occurencies;
}

Sometimes a dependency added with ng add will add more than one package, typing npm uninstall lib1 lib2 could be error prone and slow, so just remove the not needed libraries from package.json and run npm i

Make sure that the branch you are trying to push to isn't protected. I was trying to push to a protected branch and failed same as you.

Get-ChildItem -Recurse *.txt | Format-Table FullName

That is what I used. I feel it is more understandable as it doesn't contain any loop syntax.

To solve the issue you must assign the proper ownership permissions. Try the below which should resolve all permission related issues for specific users but as stated in the comments this should not be used in production:

root@server:/var/log/postgresql# sudo -u postgres psql
psql (8.4.4)
Type "help" for help.

postgres=# \du
               List of roles
    Role name    | Attributes  | Member of
-----------------+-------------+-----------
 <user-name>    | Superuser   | {}
                 : Create DB
 postgres       | Superuser   | {}
                 : Create role
                 : Create DB

postgres=# alter role <user-name> superuser;
ALTER ROLE
postgres=#

So connect to the database under a Superuser account sudo -u postgres psql and execute a ALTER ROLE <user-name> Superuser; statement.

Keep in mind this is not the best solution on multi-site hosting server so take a look at assigning individual roles instead: https://www.postgresql.org/docs/current/static/sql-set-role.html and https://www.postgresql.org/docs/current/static/sql-alterrole.html.

The first improvement would be to simplify the three cases in the main loop: Rather than iterating while some of the sequence has elements, iterate while both sequences have elements. When leaving the loop, one of them will be empty, we don't know which, but we don't care: We append them at the end of the result.

def msort2(x):
    if len(x) < 2:
        return x
    result = []          # moved!
    mid = int(len(x) / 2)
    y = msort2(x[:mid])
    z = msort2(x[mid:])
    while (len(y) > 0) and (len(z) > 0):
        if y[0] > z[0]:
            result.append(z[0])
            z.pop(0)
        else:
            result.append(y[0])
            y.pop(0)
    result += y
    result += z
    return result

The second optimization is to avoid popping the elements. Rather, have two indices:

def msort3(x):
    if len(x) < 2:
        return x
    result = []
    mid = int(len(x) / 2)
    y = msort3(x[:mid])
    z = msort3(x[mid:])
    i = 0
    j = 0
    while i < len(y) and j < len(z):
        if y[i] > z[j]:
            result.append(z[j])
            j += 1
        else:
            result.append(y[i])
            i += 1
    result += y[i:]
    result += z[j:]
    return result

A final improvement consists in using a non recursive algorithm to sort short sequences. In this case I use the built-in sorted function and use it when the size of the input is less than 20:

def msort4(x):
    if len(x) < 20:
        return sorted(x)
    result = []
    mid = int(len(x) / 2)
    y = msort4(x[:mid])
    z = msort4(x[mid:])
    i = 0
    j = 0
    while i < len(y) and j < len(z):
        if y[i] > z[j]:
            result.append(z[j])
            j += 1
        else:
            result.append(y[i])
            i += 1
    result += y[i:]
    result += z[j:]
    return result

My measurements to sort a random list of 100000 integers are 2.46 seconds for the original version, 2.33 for msort2, 0.60 for msort3 and 0.40 for msort4. For reference, sorting all the list with sorted takes 0.03 seconds.

Take a look at Job Control on UNIX systems

If you don't have control of your shell, simply hitting ctrl + C should stop the process. If that doesn't work, you can try ctrl + Z and using the jobs and kill -9 %<job #> to kill it. The '-9' is a type of signal. You can man kill to see a list of signals.

Dont worry. First you may clean the project, then run the project. If this does not work then follow the following links:

You could also try with perl (credit goes here)

perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/'  file1 file2

The layouts in /res/layout are applied to both portrait and landscape, unless you specify otherwise. Let’s assume we have /res/layout/home.xml for our homepage and we want it to look differently in the 2 layout types.

1. create folder /res/layout-land (here you will keep your landscape adjusted layouts)
2. copy home.xml there
3. make necessary changes to it

You ran into Eclipse bug 525948 which has already been fixed and which will be published in the upcoming release Oxygen.3 (4.7.3), March 21, 2018.

As workaround, put your test code in a separate project and add the project under test to the modulepath, but do not add a module-info.java to your test project. With your project, class and module naming, it should look something like this:

JSAES is a powerful implementation of AES in JavaScript. http://point-at-infinity.org/jsaes/

You can try this solution, since onkeypress will be attached directly to the DOM element and will prevent users from entering invalid data to begin with.

So no side-effects on react side.

<input type="text" onKeyPress={onNumberOnlyChange}/>

const onNumberOnlyChange = (event: any) => {
    const keyCode = event.keyCode || event.which;
    const keyValue = String.fromCharCode(keyCode);
    const isValid = new RegExp("[0-9]").test(keyValue);
    if (!isValid) {
       event.preventDefault();
       return;
    }
};

There is no easy way to remove the "outdated" stuff from an existing workspace. Using the "clean" parameter will not really help, as many of the files you refer to are "free form data", only known to the plugins that are no longer available.

Your best bet is to optimize the re-import, where I would like to point out the following:

• When creating a new workspace, you can already choose to have some settings being copied from the current to the new workspace.
• You can export the preferences of the current workspace (using the Export menu) and re-import them in the new workspace.
• There are lots of recommendations on the Internet to just copy the ${old_workspace}/.metadata/.plugins/org.eclipse.core.runtime/.settings folder from the old to the new workspace. This is surely the fastest way, but it may lead to weird behaviour, because some of your plugins may depend on these settings and on some of the mentioned "free form data" stored elsewhere. (There are even people symlinking these folders over multiple workspaces, but this really requires to use the same plugins on all workspaces.)
• You may want to consider using more project specific settings than workspace preferences in the future. So for instance all the Java compiler settings can either be set on the workspace level or on the project level. If set on the project level, you can put them under version control and are independent of the workspace.

I usually curse MS word and then run the following Wscript.

PATH = "test.html"

var go=WScript.CreateObject("Scripting.FileSystemObject");
var content=go.GetFile(PATH).OpenAsTextStream().ReadAll();
var out=go.CreateTextFile("clean-"+PATH, true);

// symbols
content=content.replace(/“/g,'"');
content=content.replace(/”/g,'"');
content=content.replace(/’/g,"'");
content=content.replace(/–/g,"-");
content=content.replace(/©/g,"&copy;");

How about:

In fact, in R, this operation is very easy:

If the matrix 'a' contains some NaN, you just need to use the following code to replace it by 0:

a <- matrix(c(1, NaN, 2, NaN), ncol=2, nrow=2)
a[is.nan(a)] <- 0
a

If the data frame 'b' contains some NaN, you just need to use the following code to replace it by 0:

#for a data.frame: 
b <- data.frame(c1=c(1, NaN, 2), c2=c(NaN, 2, 7))
b[is.na(b)] <- 0
b

Note the difference is.nan when it's a matrix vs. is.na when it's a data frame.

Doing

#...
b[is.nan(b)] <- 0
#...

yields: Error in is.nan(b) : default method not implemented for type 'list' because b is a data frame.

I have never parsed ini files, so I can't be too specific on this issue.
But i have one advice:
Don't reinvent the wheel as long as an existing one meets your requirements

http://en.wikipedia.org/wiki/INI_file#Accessing_INI_files
http://sdl-cfg.sourceforge.net/
http://sourceforge.net/projects/libini/
http://www.codeproject.com/KB/files/config-file-parser.aspx

Good luck :)

I know others have mentioned String.split, but here is a variant that only yields two tokens (the base and the extension):

String[] tokens = fileName.split("\\.(?=[^\\.]+$)");

For example:

"test.cool.awesome.txt".split("\\.(?=[^\\.]+$)");

Yields:

["test.cool.awesome", "txt"]

The regular expression tells Java to split on any period that is followed by any number of non-periods, followed by the end of input. There is only one period that matches this definition (namely, the last period).

Technically Regexically speaking, this technique is called zero-width positive lookahead.

BTW, if you want to split a path and get the full filename including but not limited to the dot extension, using a path with forward slashes,

    String[] tokens = dir.split(".+?/(?=[^/]+$)");

For example:

    String dir = "/foo/bar/bam/boozled"; 
    String[] tokens = dir.split(".+?/(?=[^/]+$)");
    // [ "/foo/bar/bam/" "boozled" ] 

Unless I am misunderstanding the question, I would almost always use $this->get_species because the subclass (in this case dog) could overwrite that method since it does extend it. If the class dog doesn't redefine the method then both ways are functionally equivalent but if at some point in the future you decide you want the get_species method in dog should print "dog" then you would have to go back through all the code and change it.

When you use $this it is actually part of the object which you created and so will always be the most up-to-date as well (if the property being used has changed somehow in the lifetime of the object) whereas using the parent class is calling the static class method.

The clean, install and deploy phases are valid lifecycle phases and invoking them will trigger all the phases preceding them, and the goals bound to these phases.

mvn clean install

This command invokes the clean phase and then the install phase sequentially:

• clean: removes files generated at build-time in a project's directory (target by default)
• install: installs the package into the local repository, for use as a dependency in other projects locally.

mvn deploy

This command invokes the deploy phase:

• deploy: copies the final package to the remote repository for sharing with other developers and projects.

mvn release

This is not a valid phase nor a goal so this won't do anything. But if refers to the Maven Release Plugin that is used to automate release management. Releasing a project is done in two steps: prepare and perform. As documented:

Preparing a release goes through the following release phases:

• Check that there are no uncommitted changes in the sources
• Check that there are no SNAPSHOT dependencies
• Change the version in the POMs from x-SNAPSHOT to a new version (you will be prompted for the versions to use)
• Transform the SCM information in the POM to include the final destination of the tag
• Run the project tests against the modified POMs to confirm everything is in working order
• Commit the modified POMs
• Tag the code in the SCM with a version name (this will be prompted for)
• Bump the version in the POMs to a new value y-SNAPSHOT (these values will also be prompted for)
• Commit the modified POMs

And then:

Performing a release runs the following release phases:

• Checkout from an SCM URL with optional tag
• Run the predefined Maven goals to release the project (by default, deploy site-deploy)

In Netbeans you can right click on the project and run it, but in IntelliJ IDEA you have to select the index.jsp file or the welcome file to run the project.

this is because Netbeans generate the following tag in web.xml and IntelliJ do not.

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

The only solution that worked for me was this command :

docker-compose build --no-cache

This will automatically pull fresh image from repo and won't use the cache version that is prebuild with any parameters you've been using before.

The package sciplot has the built-in function se(x)

Much better way to limit the range... used the contains logic from above poster.

                                         });

google.maps.event.addListener(this.googleMap, 'dragend', function(){
                            if (mapBounds.contains(map.getCenter())) return;
                    map.setCenter(this.dragStart);
                           });

style:

.parent{
  overflow:hidden;

$('#OvernightOnshore').click(function () {
    if ($('#OvernightOnshore').prop("checked") == true) {
        if ($('#OvernightOffshore').prop("checked") == true) {
            $('#OvernightOffshore').attr('checked', false)
        }
    }
})

$('#OvernightOffshore').click(function () {
    if ($('#OvernightOffshore').prop("checked") == true) {
        if ($('#OvernightOnshore').prop("checked") == true) {
            $('#OvernightOnshore').attr('checked', false);
        }
    }
})

This above code snippet will allow you to use checkboxes over radio buttons, but have the same functionality of radio buttons where you can only have one selected.

If you're going to compile a 64bit version(x86_64) of php use: /usr/lib64/

For architectures (i386 ... i686) use /usr/lib/

I recommend compiling php to the same architecture as apache. As you're using a 64bit linux i asume your apache is also compiled for x86_64.

like so:

BEGIN TRANSACTION; 
UPDATE table_name
  SET column_name=REPLACE(column_name,'text_to_find','replace_with_this'); 
COMMIT TRANSACTION;

Example: Replaces <script... with <a ... to eliminate javascript vulnerabilities

BEGIN TRANSACTION; UPDATE testdb
SET title=REPLACE(title,'script','a'); COMMIT TRANSACTION;

Here is the example:

SQL> set define off;
SQL> select * from dual where dummy='&var';

no rows selected

SQL> set define on
SQL> /
Enter value for var: X
old   1: select * from dual where dummy='&var'
new   1: select * from dual where dummy='X'

D
-
X

With set define off, it took a row with &var value, prompted a user to enter a value for it and replaced &var with the entered value (in this case, X).

Check your short_open_tag setting (use <?php phpinfo() ?> to see its current setting).

The problem doesn't seem to be with the variable but rather with the declaration of ACTInterface. Is ACTInterface declared as internal by any chance?

Instead of explicitly writing the class name you could use

this.getClass().getResource("/unibo/lsb/res/dice.jpg");

You could use startOf('day') method to compare just the date

Example :

var dateToCompare = moment("06/04/2015 18:30:00");
var today = moment(new Date());

dateToCompare.startOf('day').isSame(today.startOf('day'));

Use simple and easy code

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        let myCell = tableView.dequeueReusableCellWithIdentifier("mannaCustumCell") as! CustomCell
        let heightForCell = myCell.bounds.size.height;

        return heightForCell;
    }

If you'd like to know what is the numeric version of FireFox you can use the following snippet:

var match = window.navigator.userAgent.match(/Firefox\/([0-9]+)\./);
var ver = match ? parseInt(match[1]) : 0;

You can determin mousewhell direction.

$(window).on('mousewheel DOMMouseScroll', function (e) {
    var delta = e.originalEvent.wheelDelta ? 
                   e.originalEvent.wheelDelta : -e.originalEvent.detail;

    if (delta >= 0) {
        console.log('scroll up');
    } else {
        console.log('scroll down');
    }
});

Sometimes you may get "Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/classworlds/Launcher" even after setting M2_HOME and PATH parameters correctly.

This exception is because your JDK/Java version need to be updated/installed.

I found that doing it in two relatively simple steps seemed to work quite well. The first css definition for ul sets the base indent that you want for the list as a whole. The second definition sets the indent value for each nested list item within it. In my case they are the same, but you can obviously pick whatever you want.

ul {
    margin-left: 1.5em;
}

ul > ul {
    margin-left: 1.5em;
}

But can I abort a Task (in .Net 4.0) in the same way not by cancellation mechanism. I want to kill the Task immediately.

Other answerers have told you not to do it. But yes, you can do it. You can supply Thread.Abort() as the delegate to be called by the Task's cancellation mechanism. Here is how you could configure this:

class HardAborter
{
  public bool WasAborted { get; private set; }
  private CancellationTokenSource Canceller { get; set; }
  private Task<object> Worker { get; set; }

  public void Start(Func<object> DoFunc)
  {
    WasAborted = false;

    // start a task with a means to do a hard abort (unsafe!)
    Canceller = new CancellationTokenSource();

    Worker = Task.Factory.StartNew(() => 
      {
        try

disclaimer: don't do this.

Here is an example of what not to do:

 var doNotDoThis = new HardAborter();

 // start a thread writing to the console
 doNotDoThis.Start(() =>
    {
       while (true)
       {
          Thread.Sleep(100);
          Console.Write(".");
       }
       return null;
    });


 // wait a second to see some output and show the WasAborted value as false
 Thread.Sleep(1000);
 Console.WriteLine("WasAborted: " + doNotDoThis.WasAborted);

 // wait another second, abort, and print the time
 Thread.Sleep(1000);
 doNotDoThis.Abort();
 Console.WriteLine("Abort triggered at " + DateTime.Now);

 // wait until the abort finishes and print the time
 while (!doNotDoThis.WasAborted) { Thread.CurrentThread.Join(0); }
 Console.WriteLine("WasAborted: " + doNotDoThis.WasAborted + " at " + DateTime.Now);

 Console.ReadKey();

What about this?
Destructor is not called if an exception is thrown from the constructor, so I have to call it manually to destroy handles that have been created in the constructor before the exception.

class MyClass {
  HANDLE h1,h2;
  public:
  MyClass() {
    // handles have to be created first
    h1=SomeAPIToCreateA();
    h2=SomeAPIToCreateB();        
    try {
      ...
      if(error) {
        throw MyException();
      }
    }
    catch(...) {
      this->~MyClass();
      throw;
    }
  }
  ~MyClass() {
    SomeAPIToDestroyA(h1);
    SomeAPIToDestroyB(h2);
  }
};

1. Download the "google-service.json" file from Firebase
2. Go to this address in windows explorer "C:\Users\Your-Username\AndroidStudioProjects" You will see a list of your Android Studio projects
3. Open a desired project, navigate to "app" folder and paste the .json file
4. Go to Android Studio and click on "Sync with file system", located in dropdown menu (File>Sync with file system)
5. Now sync with Gradle and everything should be fine

There are two reasons I see to use cte's.

To use a calculated value in the where clause. This seems a little cleaner to me than a derived table.

Suppose there are two tables - Questions and Answers joined together by Questions.ID = Answers.Question_Id (and quiz id)

WITH CTE AS
(
    Select Question_Text,
           (SELECT Count(*) FROM Answers A WHERE A.Question_ID = Q.ID) AS Number_Of_Answers
    FROM Questions Q
)
SELECT * FROM CTE
WHERE Number_Of_Answers > 0

Here's another example where I want to get a list of questions and answers. I want the Answers to be grouped with the questions in the results.

WITH cte AS
(
    SELECT [Quiz_ID] 
      ,[ID] AS Question_Id
      ,null AS Answer_Id
          ,[Question_Text]
          ,null AS Answer
          ,1 AS Is_Question
    FROM [Questions]

    UNION ALL

    SELECT Q.[Quiz_ID]
      ,[Question_ID]
      ,A.[ID] AS  Answer_Id
      ,Q.Question_Text
          ,[Answer]
          ,0 AS Is_Question
        FROM [Answers] A INNER JOIN [Questions] Q ON Q.Quiz_ID = A.Quiz_ID AND Q.Id = A.Question_Id
)
SELECT 
    Quiz_Id,
    Question_Id,
    Is_Question,
    (CASE WHEN Answer IS NULL THEN Question_Text ELSE Answer END) as Name
FROM cte    
GROUP BY Quiz_Id, Question_Id, Answer_id, Question_Text, Answer, Is_Question 
order by Quiz_Id, Question_Id, Is_Question Desc, Name

No, IIRC there is no getopt() on Windows.

Boost, however, has the program_options library... which works okay. It will seem like overkill at first, but it isn't terrible, especially considering it can handle setting program options in configuration files and environment variables in addition to command line options.

I'm able to execute your exact query by just making sure there is a semicolon at the end of my select statement. (Output is actual, connection params removed.)

echo "select 1 from dual;" | sqlplus -s username/password@host:1521/service 

Output:

         1
----------
         1

Note that is should matter but this is running on Mac OS X Snow Leopard and Oracle 11g.

The following function does the trick and keeps all the attributes. You use it for example like this: changeTag("div", "p")

function changeTag(originTag, destTag) {
  while($(originTag).length) {
    $(originTag).replaceWith (function () {
      var attributes = $(this).prop("attributes");
      var $newEl = $(`<${destTag}>`)
      $.each(attributes, function() {
        $newEl.attr(this.name, this.value);
      });  
      return $newEl.html($(this).html())
    })
  }
}

To be sure that it works, check the following example

function changeTag(originTag, destTag) {_x000D_
  while($(originTag).length) {_x000D_
    $(originTag).replaceWith (function () {_x000D_
      var attributes = $(this).prop("attributes");_x000D_
      var $newEl = $(`<${destTag}>`)_x000D_
      $.each(attributes, function() {_x000D_
        $newEl.attr(this.name, this.value);_x000D_
      });  _x000D_
      return $newEl.html($(this).html())_x000D_
    })_x000D_
  }_x000D_
}_x000D_
_x000D_
changeTag("div", "p")_x000D_

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):

1) Commits on remote branch since when local branch was created:

git diff HEAD...origin/master

2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:

git diff origin/master...HEAD

3) See the answer by dbyrne.

If you're using C# 6 or later, you can use expression-bodied syntax for get-only indexer:

public object this[int i] => this.InnerList[i];

   $filename=mktime().'_'.$_FILES['import']['name'];

      $path='common/csv/'.$filename;

    if(move_uploaded_file($_FILES['import']['tmp_name'],$path))
{

if(mysql_query("load data local infile '".$path."' INTO TABLE tbl_customer FIELDS TERMINATED BY ',' enclosed by '\"' LINES TERMINATED BY '\n' IGNORE 1 LINES (`location`, `maildropdate`,`contact_number`,`first_name`,`mname`,`lastname`,`suffix`,`address`,`city`,`state`,`zip`)"))

    {
      echo "imported successfully";

}

echo "<br>"."Uploaded Successfully".$path;

}

The best way of retrieving a checkbox's value is as following

if ( elem.checked ) 
if ( $( elem ).prop( "checked" ) ) 
if ( $( elem ).is( ":checked" ) ) 

as explained in the official documentations in jQuery's website. The rest of the methods has nothing to do with the property of the checkbox, they are checking the attribute which means they are testing the initial state of the checkbox when it was loaded. So in short:

• When you have the element and you know it is a checkbox you can simply read its property and you won't need jQuery for that (i.e. elem.checked) or you can use $(elem).prop("checked") if you want to rely on jQuery.
• If you need to know (or compare) the value when the element was first loaded (i.e. the default value) the correct way to do it is elem.getAttribute("checked") or elem.prop("defaultChecked").

Please note that elem.attr("checked") is modified only after version 1.6.1+ of jQuery to return the same result as elem.prop("checked").

Some answers are misleading or imprecise, Please check below yourself:

http://api.jquery.com/prop/

Add checked to both of your radio button. And then show/hide your desired one on document ready.

You can use .filter() with boolean operators ie &&:

     var find = my_array.filter(function(result) {
       return result.param1 === "srting1" && result.param2 === 'string2';
     });
     
     return find[0];

It's been a long time since I've worked in a Windows environment, but I would suggest that you look at using WMI.

I came across this post while searching for a way to clear the entire form related to the BFCache (back/forward button cache) in Chrome.

In addition to what Sim supplied, my use case required that the details needed to be combined with Clear Form on Back Button?.

I found that the best way to do this is in allow the form to behave as it expects, and to trigger an event:

$(window).bind("pageshow", function() {
    var form = $('form'); 
    // let the browser natively reset defaults
    form[0].reset();
});

If you are not handling the input events to generate an object in JavaScript, or something else for that matter, then you are done. However, if you are listening to the events, then at least in Chrome you need to trigger a change event yourself (or whatever event you care to handle, including a custom one):

form.find(':input').not(':button,:submit,:reset,:hidden').trigger('change');

That must be added after the reset to do any good.

window.frames['myIFrame'].document.getElementById('myIFrameElemId')

not working for me but I found another solution. Use:

window.frames['myIFrame'].contentDocument.getElementById('myIFrameElemId')

I checked it on Firefox and Chrome.

/usr/local/lib/node_modules is the correct directory for globally installed node modules.

/usr/local/share/npm/lib/node_modules makes no sense to me. One issue here is that you're confused because there are two directories called node_modules:

/usr/local/lib/node_modules
/usr/local/lib/node_modules/npm/node_modules

The latter seems to be node modules that came with Node, e.g., lodash, when the former is Node modules that I installed using npm.

SELECT (column name) FROM (table name) WHERE (column name) < DATEADD(Day,-30,GETDATE());

Example.

SELECT `name`, `phone`, `product` FROM `tbmMember` WHERE `dateofServicw` < (Day,-30,GETDATE()); 

std::string trimmed(std::string str ) {
if(str.length() == 0 ) { return "" ; }
else if ( str == std::string(" ") ) { return "" ; } 
else {
    while(str.at(0) == ' ') { str.erase(0, 1);}
    while(str.at(str.length()-1) == ' ') { str.pop_back() ; }
    return str ;
    } 
}

I was able to fix the sub-menu's always pinning to the top of the parent menu from Andres's answer with the following addition:

.dropdown-menu li {
    position: relative;
}

I also add an icon "icon-chevron-right" on items which contain menu sub-menus, and change the icon from black to white on hover (to compliment the text changing to white and look better with the selected blue background).

Here is the full less/css change (replace the above with this):

.dropdown-menu li {
    position: relative;

    [class^="icon-"] {
        float: right;
    }

    &:hover {
        // Switch to white icons on hover
        [class^="icon-"] {
            background-image: url("../img/glyphicons-halflings-white.png");
        }
    }
}

You can try this. :) simple solution!

=IF(ISNUMBER(MATCH(I1,E:E,0)),"TRUE","")

The correct answer to this particular questions is "don't select". Sometimes you have to select or activate, but 99% of the time you don't. If your code looks like

Select something
Do something to the selection
Select something else
Do something to the selection

You probably need to refactor and consider not selecting.

The error, Method 'Range' of object '_Worksheet' failed, error 1004, that you're getting is because the sheet with the button on it doesn't have a range named "Result". Most (maybe all) properties that return an object have a default Parent object. In this case, you're using the Range property to return a Range object. Because you don't qualify the Range property, Excel uses the default.

The default Parent object can be different based on the circumstances. If your code were in a standard module, then the ActiveSheet would be the default Parent and Excel would try to resolve ActiveSheet.Range("Result"). Your code is in a sheet's class module (the sheet with the button on it). When the unqualified reference is used there, the default Parent is the sheet that's attached to that module. In this case they're the same because the sheet has to be active to click the button, but that isn't always the case.

When Excel gives the error that includes text like '_Object' (yours said '_Worksheet') it's always referring to the default Parent object - the underscore gives that away. Generally the way to fix that is to qualify the reference by being explicit about the parent. But in the case of selecting and activating when you don't need to, it's better to just refactor the code.

Here's one way to write your code without any selecting or activating.

Private Sub cmdRecord_Click()

    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim rNext As Range

    'Me refers to the sheet whose class module you're in
    'Me.Parent refers to the workbook
    Set shSource = Me.Parent.Worksheets("BxWsn Simulation")
    Set shDest = Me.Parent.Worksheets("Reslt Record")

    Set rNext = shDest.Cells(shDest.Rows.Count, 1).End(xlUp).Offset(1, 0)

    shSource.Range("Result").Copy
    rNext.PasteSpecial xlPasteFormulasAndNumberFormats

    Application.CutCopyMode = False

End Sub

When I'm in a class module, like the sheet's class module that you're working in, I always try to do things in terms of that class. So I use Me.Parent instead of ActiveWorkbook. It makes the code more portable and prevents unexpected problems when things change.

I'm sure the code you have now runs in milliseconds, so you may not care, but avoiding selecting will definitely speed up your code and you don't have to set ScreenUpdating. That may become important as your code grows or in a different situation.

Let's assume you have the following directory structure: -

main/ fold1 fold2 fold3...

folders = glob.glob("main/fold*")

for fold in folders:
    abspath = os.path.dirname(os.path.abspath(fold))
    fullpath = os.path.join(abspath, sch)
    print(fullpath)

Just to confirm though you probably did...

Did you include the

<!--  tell spring to use annotation based congfigurations -->
<context:annotation-config />
<!--  tell spring where to find the beans -->
<context:component-scan base-package="zz.yy.abcd" />

bits in your application context.xml?

Also I'm not so sure you'd be able to use a jta transaction type with this kind of setup? Wouldn't that require a data source managed connection pool? So try RESOURCE_LOCAL instead.

I think this clause is wrong:

if (!CGRectContainsPoint(aRect, activeField!.frame.origin))

While the activeField's origin may well be above the keyboard, the maxY might not...

I would create a 'max' point for the activeField and check if that is in the keyboard Rect.

Well you have to setup the click event first then you can trigger it and see what happens:

//good habits first let's cache our selector
var $myLink = $('#titleee').find('a');
$myLink.click(function (evt) {
  evt.preventDefault();
  alert($(this).attr('href'));
});

// now the manual trigger
$myLink.trigger('click');

For HttpEntity, the below answer works

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);

ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

For reference: How to POST form data with Spring RestTemplate?

Here is something I think will work for what you want, using a decorator.

class LogWrappedFunction(object):
    def __init__(self, function):
        self.function = function

    def logAndCall(self, *arguments, **namedArguments):
        print "Calling %s with arguments %s and named arguments %s" %\
                      (self.function.func_name, arguments, namedArguments)
        self.function.__call__(*arguments, **namedArguments)

def logwrap(function):
    return LogWrappedFunction(function).logAndCall

@logwrap
def doSomething(spam, eggs, foo, bar):
    print "Doing something totally awesome with %s and %s." % (spam, eggs)


doSomething("beans","rice", foo="wiggity", bar="wack")

Run it, it will yield the following output:

C:\scripts>python decoratorExample.py
Calling doSomething with arguments ('beans', 'rice') and named arguments {'foo':
 'wiggity', 'bar': 'wack'}
Doing something totally awesome with beans and rice.

Why not just make the access_token last as long as the refresh_token and not have a refresh_token?

In addition to great answers other people have provided, there is another reason why we would use refresh tokens and it's to do with claims.

Each token contains claims which can include anything from the user's name, their roles, or the provider which created the claim. As a token is refreshed, these claims are updated.

If we refresh the tokens more often, we are obviously putting more strain on our identity services; however, we are getting more accurate and up-to-date claims.

For cv::Mat_<T> mat just use mat(row, col)

Accessing elements of a matrix with specified type cv::Mat_< _Tp > is more comfortable, as you can skip the template specification. This is pointed out in the documentation as well.

code:

cv::Mat1d mat0 = cv::Mat1d::zeros(3, 4);
std::cout << "mat0:\n" << mat0 << std::endl;
std::cout << "element: " << mat0(2, 0) << std::endl;
std::cout << std::endl;

cv::Mat1d mat1 = (cv::Mat1d(3, 4) <<
    1, NAN, 10.5, NAN,
    NAN, -99, .5, NAN,
    -70, NAN, -2, NAN);
std::cout << "mat1:\n" << mat1 << std::endl;
std::cout << "element: " << mat1(0, 2) << std::endl;
std::cout << std::endl;

cv::Mat mat2 = cv::Mat(3, 4, CV_32F, 0.0);
std::cout << "mat2:\n" << mat2 << std::endl;
std::cout << "element: " << mat2.at<float>(2, 0) << std::endl;
std::cout << std::endl;

output:

mat0:
[0, 0, 0, 0;
 0, 0, 0, 0;
 0, 0, 0, 0]
element: 0

mat1:
[1, nan, 10.5, nan;
 nan, -99, 0.5, nan;
 -70, nan, -2, nan]
element: 10.5

mat2:
[0, 0, 0, 0;
 0, 0, 0, 0;
 0, 0, 0, 0]
element: 0

In the absence of more detailed info:

using(var dbContext = new dbDataContext())
{
    var data = dbContext.SomeTable.SingleOrDefault(row => row.id == requiredId);
    if(data != null)
    {
        data.SomeField = newValue;
    }
    dbContext.SubmitChanges();
}

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

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

Is it possible to have multiple version of tensorflow on the same OS?

Yes, you can use python virtual environments for this. From the docs:

A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them. It solves the “Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keeps your global site-packages directory clean and manageable.

After you have install virtualenv (see the docs), you can create a virtual environment for the tutorial and install the tensorflow version you need in it:

PATH_TO_PYTHON=/usr/bin/python3.5
virtualenv -p $PATH_TO_PYTHON my_tutorial_env 
source my_tutorial_env/bin/activate # this activates your new environment
pip install tensorflow==1.1

PATH_TO_PYTHON should point to where python is installed on your system. When you want to use the other version of tensorflow execute:

deactivate my_tutorial_env

Now you can work again with the tensorflow version that was already installed on your system.

For me this problem keeps appearing after I run the APK at first time. Invalidating did not help.
However, I came with a workaround:
Just run the APK, and while it's running you can submit your changes clicking the "Lightning" button (Apply changes) next to to the "Run" button at the top right panel. Works charming for me, when making changes to the layout.

The POSIX specification for find says:

-mtimen The primary shall evaluate as true if the file modification time subtracted from the initialization time, divided by 86400 (with any remainder discarded), is n.

Interestingly, the description of find does not further specify 'initialization time'. It is probably, though, the time when find is initialized (run).

In the descriptions, wherever n is used as a primary argument, it shall be interpreted as a decimal integer optionally preceded by a plus ( '+' ) or minus-sign ( '-' ) sign, as follows:

+n More than n.
  n Exactly n.
-n Less than n.

At the given time (2014-09-01 00:53:44 -4:00, where I'm deducing that AST is Atlantic Standard Time, and therefore the time zone offset from UTC is -4:00 in ISO 8601 but +4:00 in ISO 9945 (POSIX), but it doesn't matter all that much):

1409547224 = 2014-09-01 00:53:44 -04:00
1409457540 = 2014-08-30 23:59:00 -04:00

so:

1409547224 - 1409457540 = 89684
89684 / 86400 = 1

Even if the 'seconds since the epoch' values are wrong, the relative values are correct (for some time zone somewhere in the world, they are correct).

The n value calculated for the 2014-08-30 log file therefore is exactly 1 (the calculation is done with integer arithmetic), and the +1 rejects it because it is strictly a > 1 comparison (and not >= 1).

curl without any options will perform a GET request. It will simply return the data from the URI specified. Not retrieve the file itself to your local machine.

When you do,

$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png

You will receive binary data:

                   |?>?$! <R?HP@T*?Pm?Z??jU???ZP+UAUQ@?
??{X\? K???>0c?yF[i?}4?!?V¸?H_?)nO#?;I??vg^_ ??-Hm$$N0.
???%Y[?L?U3?_^9??P?T?0'u8?l?4 ...

In order to save this, you can use:

$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png > image.png

to store that raw image data inside of a file.

An easier way though, is just to use wget.

$ wget https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
$ ls

Doing Project -> Clean... fixed it for me.

My eclipse had stopped working so I cleaned workspace directory and after I run eclipse when I import the project I had this problem. Other solutions suggested here didn't work.

I'm suggest that you learn about Jquery, most popular JS library. With jquery it's simple to acomplish what you want.Simle example below:

$(“#DIV_YOU_WANT_CHANGE”).click(function() {
    $(this).addClass(“.your_class_with_new_color”);
}); 

The above answers get at the most fundamental aspects of the C++ memory model. In practice, most uses of std::atomic<> "just work", at least until the programmer over-optimizes (e.g., by trying to relax too many things).

There is one place where mistakes are still common: sequence locks. There is an excellent and easy-to-read discussion of the challenges at https://www.hpl.hp.com/techreports/2012/HPL-2012-68.pdf. Sequence locks are appealing because the reader avoids writing to the lock word. The following code is based on Figure 1 of the above technical report, and it highlights the challenges when implementing sequence locks in C++:

atomic<uint64_t> seq; // seqlock representation
int data1, data2;     // this data will be protected by seq

T reader() {
    int r1, r2;
    unsigned seq0, seq1;
    while (true) {
        seq0 = seq;
        r1 = data1; // INCORRECT! Data Race!
        r2 = data2; // INCORRECT!
        seq1 = seq;

        // if the lock didn't change while I was reading, and
        // the lock wasn't held while I was reading, then my
        // reads should be valid
        if (seq0 == seq1 && !(seq0 & 1))
            break;
    }
    use(r1, r2);
}

void writer(int new_data1, int new_data2) {
    unsigned seq0 = seq;
    while (true) {
        if ((!(seq0 & 1)) && seq.compare_exchange_weak(seq0, seq0 + 1))
            break; // atomically moving the lock from even to odd is an acquire
    }
    data1 = new_data1;
    data2 = new_data2;
    seq = seq0 + 2; // release the lock by increasing its value to even
}

As unintuitive as it seams at first, data1 and data2 need to be atomic<>. If they are not atomic, then they could be read (in reader()) at the exact same time as they are written (in writer()). According to the C++ memory model, this is a race even if reader() never actually uses the data. In addition, if they are not atomic, then the compiler can cache the first read of each value in a register. Obviously you wouldn't want that... you want to re-read in each iteration of the while loop in reader().

It is also not sufficient to make them atomic<> and access them with memory_order_relaxed. The reason for this is that the reads of seq (in reader()) only have acquire semantics. In simple terms, if X and Y are memory accesses, X precedes Y, X is not an acquire or release, and Y is an acquire, then the compiler can reorder Y before X. If Y was the second read of seq, and X was a read of data, such a reordering would break the lock implementation.

The paper gives a few solutions. The one with the best performance today is probably the one that uses an atomic_thread_fence with memory_order_relaxed before the second read of the seqlock. In the paper, it's Figure 6. I'm not reproducing the code here, because anyone who has read this far really ought to read the paper. It is more precise and complete than this post.

The last issue is that it might be unnatural to make the data variables atomic. If you can't in your code, then you need to be very careful, because casting from non-atomic to atomic is only legal for primitive types. C++20 is supposed to add atomic_ref<>, which will make this problem easier to resolve.

To summarize: even if you think you understand the C++ memory model, you should be very careful before rolling your own sequence locks.

Here is a method for getting a random color:

private static Random sRandom;

public static synchronized int randomColor() {
    if (sRandom == null) {
        sRandom = new Random();
    }
    return 0xff000000 + 256 * 256 * sRandom.nextInt(256) + 256 * sRandom.nextInt(256)
            + sRandom.nextInt(256);
}

Benefits:

• Get the integer representation which can be used with java.awt.Color or android.graphics.Color
• Keep a static reference to Random.

Before creating a new branch always the best practice is to have the latest of repo in your local machine. Follow these steps for error free branch creation.

 1. $ git branch (check which branches exist and which one is currently active (prefixed with *). This helps you avoid creating duplicate/confusing branch name)
 2. $ git branch <new_branch> (creates new branch)
 3. $ git checkout new_branch
 4. $ git add . (After making changes in the current branch)
 5. $ git commit -m "type commit msg here"
 6. $ git checkout master (switch to master branch so that merging with new_branch can be done)
 7. $ git merge new_branch (starts merging)
 8. $ git push origin master (push to the remote server)

I referred this blog and I found it to be a cleaner approach.

I know that this is an old question, but as I was googling it was the first link in a results. So here is the jsp solution:

<form action="some.jsp">
  <select name="item">
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
  </select>
  <input type="submit" value="Submit">
</form>

in some.jsp

request.getParameter("item");

this line will return the selected option (from the example it is: 1, 2 or 3)

1. replace all single quotes with double quotes
2. replace 'u"' from your strings to '"' ... so basically convert internal unicodes to strings before loading the string into json

>> strs = "{u'key':u'val'}"
>> strs = strs.replace("'",'"')
>> json.loads(strs.replace('u"','"'))

Another option would be to use Angular's built-in pub-sub architecture in order to notify your directive to focus. Similar to the other approaches, but it's then not directly tied to a property, and is instead listening in on it's scope for a particular key.

Directive:

angular.module("app").directive("focusOn", function($timeout) {
  return {
    restrict: "A",
    link: function(scope, element, attrs) {
      scope.$on(attrs.focusOn, function(e) {
        $timeout((function() {
          element[0].focus();
        }), 10);
      });
    }
  };
});

HTML:

<input type="text" name="text_input" ng-model="ctrl.model" focus-on="focusTextInput" />

Controller:

//Assume this is within your controller
//And you've hit the point where you want to focus the input:
$scope.$broadcast("focusTextInput");

The way I fixed similar issue was by adding Month to my SELECT portion

Month DATEADD(day,Created_Date,'1971/12/31') As Month

and than I added WHERE statement

Month DATEADD(day,Created_Date,'1971/12/31') = month(getdate())-1

I had the same issue, and I couldn't comment on @Sven Marnach answer (not enough rep, gosh I remember when Stackoverflow first started...) anyway.

Adding a list of random numbers to a 10 X 10 matrix.

myNpArray = np.zeros([1, 10])
for x in range(1,11,1):
    randomList = [list(np.random.randint(99, size=10))]
    myNpArray = np.vstack((myNpArray, randomList))
myNpArray = myNpArray[1:]

Using np.zeros() an array is created with 1 x 10 zeros.

array([[0., 0., 0., 0., 0., 0., 0., 0., 0., 0.]])

Then a list of 10 random numbers is created using np.random and assigned to randomList. The loop stacks it 10 high. We just have to remember to remove the first empty entry.

myNpArray

array([[31., 10., 19., 78., 95., 58.,  3., 47., 30., 56.],
       [51., 97.,  5., 80., 28., 76., 92., 50., 22., 93.],
       [64., 79.,  7., 12., 68., 13., 59., 96., 32., 34.],
       [44., 22., 46., 56., 73., 42., 62.,  4., 62., 83.],
       [91., 28., 54., 69., 60., 95.,  5., 13., 60., 88.],
       [71., 90., 76., 53., 13., 53., 31.,  3., 96., 57.],
       [33., 87., 81.,  7., 53., 46.,  5.,  8., 20., 71.],
       [46., 71., 14., 66., 68., 65., 68., 32.,  9., 30.],
       [ 1., 35., 96., 92., 72., 52., 88., 86., 94., 88.],
       [13., 36., 43., 45., 90., 17., 38.,  1., 41., 33.]])

So in a function:

def array_matrix(random_range, array_size):
    myNpArray = np.zeros([1, array_size])
    for x in range(1, array_size + 1, 1):
        randomList = [list(np.random.randint(random_range, size=array_size))]
        myNpArray = np.vstack((myNpArray, randomList))
    return myNpArray[1:]

a 7 x 7 array using random numbers 0 - 1000

array_matrix(1000, 7)

array([[621., 377., 931., 180., 964., 885., 723.],
       [298., 382., 148., 952., 430., 333., 956.],
       [398., 596., 732., 422., 656., 348., 470.],
       [735., 251., 314., 182., 966., 261., 523.],
       [373., 616., 389.,  90., 884., 957., 826.],
       [587., 963.,  66., 154., 111., 529., 945.],
       [950., 413., 539., 860., 634., 195., 915.]])

  yearList = arrayListOf()

You made the error, for the second call, to set the size of source to the size of the target.
Anyway i bet that you want the same aspect ratio for the scaled image, so you need to compute it :

var hRatio = canvas.width / img.width    ;
var vRatio = canvas.height / img.height  ;
var ratio  = Math.min ( hRatio, vRatio );
ctx.drawImage(img, 0,0, img.width, img.height, 0,0,img.width*ratio, img.height*ratio);

i also suppose you want to center the image, so the code would be :

function drawImageScaled(img, ctx) {
   var canvas = ctx.canvas ;
   var hRatio = canvas.width  / img.width    ;
   var vRatio =  canvas.height / img.height  ;
   var ratio  = Math.min ( hRatio, vRatio );
   var centerShift_x = ( canvas.width - img.width*ratio ) / 2;
   var centerShift_y = ( canvas.height - img.height*ratio ) / 2;  
   ctx.clearRect(0,0,canvas.width, canvas.height);
   ctx.drawImage(img, 0,0, img.width, img.height,
                      centerShift_x,centerShift_y,img.width*ratio, img.height*ratio);  
}
