For anyone arriving here wondering how to deal with this problem where commas (,) and full stops (.) might be involved but the exact number format may not be known - this is how I correct a string before using parseFloat() (borrowing ideas from other answers):

function preformatFloat(float){
   if(!float){
      return '';
   };

   //Index of first comma
   const posC = float.indexOf(',');

   if(posC === -1){
      //No commas found, treat as float
      return float;
   };

   //Index of first full stop
   const posFS = float.indexOf('.');

   if(posFS === -1){
      //Uses commas and not full stops - swap them (e.g. 1,23 --> 1.23)
      return float.replace(/\,/g, '.');
   };

   //Uses both commas and full stops - ensure correct order and remove 1000s separators
   return ((posC < posFS) ? (float.replace(/\,/g,'')) : (float.replace(/\./g,'').replace(',', '.')));
};

// <-- parseFloat(preformatFloat('5.200,75'))
// --> 5200.75

At the very least, this would allow parsing of British/American and European decimal formats (assuming the string contains a valid number).

use loop

  for (int i = 0; i < dt1.Rows.Count; i++)
        {      
           dt2.Rows.Add(dt1.Rows[i][0], dt1.Rows[i][1], ...);//you have to insert all Columns...
        }

For Single Index :

 df.index.rename('new_name')

For Multi Index :

 df.index.rename(['new_name','new_name2'])

WE can also use this in latest pandas :

rename_axis

var list1 = new List<Type1>();
var list2 = new List<Type2>();

list1.ForEach(item => list2.Add(new Type2() { Prop1 = value1 }));

ANTLR mega tutorial by Gabriele Tomassetti is very helpful

It has grammar examples, examples of visitors in different languages (Java, JavaScript, C# and Python) and many other things. Highly recommended.

EDIT: other useful articles by Gabriele Tomassetti on ANTLR

As per https://stackoverflow.com/a/33859341/446250, having internet connection sharing enabled for my ethernet adapter ended up causing this problem for me. Disabling the sharing fixed the problem

Yeap, you just need to make . match newline :

$string =~ /(START)(.+?)(END)/s;

This is a nice 5-part tutorial that covers a lot of useful material: http://mobile.tutsplus.com/tutorials/phonegap/phonegap-from-scratch/

Edit I just finished a nice four part tutorial building an app to write, save, edit, & delete notes using jQuery mobile (only), it was very practical & useful, but it was also only for jQM. So, I looked to see what else they had on DZone.

I'm now going to start sorting through these search results. At a glance, it looks really promising. I remembered this post; so I thought I'd steer people to it. ?

Method1:

Inline elements do not use any width or height you specify. To avoid two div and use like this:

 <div id="container">
<img src="tree.png"  align="left"/>
<h1> A very long text(about 300 words) </h1>
</div>
    <style>
            img {
                display: inline;
                width: 100px;
                height: 100px;
            }
            h1 {
                display: inline;
            }
        </style>

Method2:

Change your CSS as follows

.container div {
    display: inline-block;
    }

Method3:

It is the simple method set width Try the following css:

.container div {
overflow:hidden;
position:relative;
width:90%;
margin-bottom:20px;
margin-top:20px;
margin-left:auto;
margin-right:auto;
}
.image {
width:70%;
display: inline-block;
float: left;
}
.texts { 
height: auto;
width: 30%;
display: inline;
}

x <-c(1,2,3)
y <-c(100,200,300)
x_name <- "cond"
y_name <- "rating"

require(reshape2)
df <- melt(data.frame(x,y))
colnames(df) <- c(x_name, y_name)
print(df)

UPDATE (2017-02-07): As an answer to @cdaringe comment - there are multiple solutions possible, one of them is below.

library(dplyr)
library(magrittr)

x <- c(1, 2, 3)
y <- c(100, 200, 300)
z <- c(1, 2, 3, 4, 5)
x_name <- "cond"
y_name <- "rating"

# Helper function to create data.frame for the chunk of the data
prepare <- function(name, value, xname = x_name, yname = y_name) {
  data_frame(rep(name, length(value)), value) %>%
    set_colnames(c(xname, yname))
}

bind_rows(
  prepare("x", x),
  prepare("y", y),
  prepare("z", z)
)

Try this...

I have used following code to read "xls and xlsx"

    <?php
    include 'excel_reader.php';       // include the class
    $excel = new PhpExcelReader;      // creates object instance of the class
    $excel->read('excel_file.xls');   // reads and stores the excel file data

    // Test to see the excel data stored in $sheets property
    echo '<pre>';
    var_export($excel->sheets);

    echo '</pre>';

    or 

 echo '<pre>';
    print_r($excel->sheets);

    echo '</pre>';

We can use map_df with purrr.

library(mice)
library(purrr)

# map_df with purrr
map_df(airquality, function(x) sum(is.na(x)))
# A tibble: 1 × 6
# Ozone Solar.R  Wind  Temp Month   Day
# <int>   <int> <int> <int> <int> <int>
# 1    37       7     0     0     0     0

The following commands worked for me:

git push origin :old-name-of-branch-on-github
git branch -m old-name-of-branch-on-github new-name-for-branch-you-want
git push origin new-name-for-branch-you-want

You can hit the key q (for quit) and it should take you to the prompt.

Short answer: Most likely, no you do not need a content-type header for HTTP GET requests. But the specs does not seem to rule out a content-type header for HTTP GET, either.

Supporting materials:

1. "Content-Type" is part of the representation (i.e. payload) metadata. Quoted from RFC 7231 section 3.1:

   3.1. Representation Metadata

   Representation header fields provide metadata about the representation. When a message includes a payload body, the representation header fields describe how to interpret the representation data enclosed in the payload body. ...

   The following header fields convey representation metadata:

   +-------------------+-----------------+
   | Header Field Name | Defined in...   |
   +-------------------+-----------------+
   | Content-Type      | Section 3.1.1.5 |
   | ...               | ...             |
   

   Quoted from RFC 7231 section 3.1.1.5(by the way, the current chosen answer had a typo in the section number):

   The "Content-Type" header field indicates the media type of the associated representation

2. In that sense, a Content-Type header is not really about an HTTP GET request (or a POST or PUT request, for that matter). It is about the payload inside such a whatever request. So, if there will be no payload, there needs no Content-Type. In practice, some implementation went ahead and made that understandable assumption. Quoted from Adam's comment:

   "While ... the spec doesn't say you can't have Content-Type on a GET, .Net seems to enforce it in it's HttpClient. See this SO q&a."

3. However, strictly speaking, the specs itself does not rule out the possibility of HTTP GET contains a payload. Quoted from RFC 7231 section 4.3.1:

   4.3.1 GET

   ...

   A payload within a GET request message has no defined semantics; sending a payload body on a GET request might cause some existing implementations to reject the request.

   So, if your HTTP GET happens to include a payload for whatever reason, a Content-Type header is probably reasonable, too.

You can check the type of any variable/instance at runtime either using the "reflect" packages TypeOf function or by using fmt.Printf():

package main

import (
   "fmt"
   "reflect"
)

func main() {
    value1 := "Have a Good Day"
    value2 := 50
    value3 := 50.78

    fmt.Println(reflect.TypeOf(value1 ))
    fmt.Println(reflect.TypeOf(value2))
    fmt.Println(reflect.TypeOf(value3))
    fmt.Printf("%T",value1)
    fmt.Printf("%T",value2)
    fmt.Printf("%T",value3)
}

Try passing columns of the DataFrame directly to matplotlib, as in the examples below, instead of extracting them as numpy arrays.

df = pd.DataFrame(np.random.randn(10,2), columns=['col1','col2'])
df['col3'] = np.arange(len(df))**2 * 100 + 100

In [5]: df
Out[5]: 
       col1      col2  col3
0 -1.000075 -0.759910   100
1  0.510382  0.972615   200
2  1.872067 -0.731010   500
3  0.131612  1.075142  1000
4  1.497820  0.237024  1700

Vary scatter point size based on another column

plt.scatter(df.col1, df.col2, s=df.col3)
# OR (with pandas 0.13 and up)
df.plot(kind='scatter', x='col1', y='col2', s=df.col3)

Vary scatter point color based on another column

colors = np.where(df.col3 > 300, 'r', 'k')
plt.scatter(df.col1, df.col2, s=120, c=colors)
# OR (with pandas 0.13 and up)
df.plot(kind='scatter', x='col1', y='col2', s=120, c=colors)

Scatter plot with legend

However, the easiest way I've found to create a scatter plot with legend is to call plt.scatter once for each point type.

cond = df.col3 > 300
subset_a = df[cond].dropna()
subset_b = df[~cond].dropna()
plt.scatter(subset_a.col1, subset_a.col2, s=120, c='b', label='col3 > 300')
plt.scatter(subset_b.col1, subset_b.col2, s=60, c='r', label='col3 <= 300') 
plt.legend()

Update

From what I can tell, matplotlib simply skips points with NA x/y coordinates or NA style settings (e.g., color/size). To find points skipped due to NA, try the isnull method: df[df.col3.isnull()]

To split a list of points into many types, take a look at numpy select, which is a vectorized if-then-else implementation and accepts an optional default value. For example:

df['subset'] = np.select([df.col3 < 150, df.col3 < 400, df.col3 < 600],
                         [0, 1, 2], -1)
for color, label in zip('bgrm', [0, 1, 2, -1]):
    subset = df[df.subset == label]
    plt.scatter(subset.col1, subset.col2, s=120, c=color, label=str(label))
plt.legend()

It's probably worth noting that IE won't cache css files called by other css files using the @import method. So, for example, if your html page links to "master.css" which pulls in "reset.css" via @import, then reset.css will not be cached by IE.

One possible solution can be

class Survey{
  void renderSurvey(Question q) {
  /*
      Depending on the type of question (choice, dropdwn or other, I have to render
      the question on the UI. The class that calls this doesnt have compile time 
      knowledge of the type of question that is going to be rendered. Each question 
      type has its own rendering function. If this is for choice , I need to access 
      its functions using q. 
  */
  if(q.getOption() instanceof ChoiceQuestionOption)
  {
    ChoiceQuestionOption choiceQuestion = (ChoiceQuestionOption)q.getOption();
    boolean result = choiceQuestion.getMultiple();
    //do something with result......
  }
 }
}

If I had to guess, I'd say that you're from a Java background. This is C++, and things are passed by value unless you specify otherwise using the &-operator (note that this operator is also used as the 'address-of' operator, but in a different context). This is all well documented, but I'll re-iterate anyway:

void foo(vector<int> bar); // by value
void foo(vector<int> &bar); // by reference (non-const, so modifiable inside foo)
void foo(vector<int> const &bar); // by const-reference

You can also choose to pass a pointer to a vector (void foo(vector<int> *bar)), but unless you know what you're doing and you feel that this is really is the way to go, don't do this.

Also, vectors are not the same as arrays! Internally, the vector keeps track of an array of which it handles the memory management for you, but so do many other STL containers. You can't pass a vector to a function expecting a pointer or array or vice versa (you can get access to (pointer to) the underlying array and use this though). Vectors are classes offering a lot of functionality through its member-functions, whereas pointers and arrays are built-in types. Also, vectors are dynamically allocated (which means that the size may be determined and changed at runtime) whereas the C-style arrays are statically allocated (its size is constant and must be known at compile-time), limiting their use.

I suggest you read some more about C++ in general (specifically array decay), and then have a look at the following program which illustrates the difference between arrays and pointers:

void foo1(int *arr) { cout << sizeof(arr) << '\n'; }
void foo2(int arr[]) { cout << sizeof(arr) << '\n'; }
void foo3(int arr[10]) { cout << sizeof(arr) << '\n'; }
void foo4(int (&arr)[10]) { cout << sizeof(arr) << '\n'; }

int main()
{
    int arr[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    foo1(arr);
    foo2(arr);
    foo3(arr);
    foo4(arr);
}

The severity level 16 in your example code is typically used for user-defined (user-detected) errors. The SQL Server DBMS itself emits severity levels (and error messages) for problems it detects, both more severe (higher numbers) and less so (lower numbers).

The state should be an integer between 0 and 255 (negative values will give an error), but the choice is basically the programmer's. It is useful to put different state values if the same error message for user-defined error will be raised in different locations, e.g. if the debugging/troubleshooting of problems will be assisted by having an extra indication of where the error occurred.

The one with no extra imports!

Their is a pythonic standard called EAFP(Easier to Ask for Forgiveness than Permission). Below code is based on that python standard.

# The A and B dictionaries
A = {'a': 1, 'b': 2, 'c': 3}
B = {'b': 3, 'c': 4, 'd': 5}

# The final dictionary. Will contain the final outputs.
newdict = {}

# Make sure every key of A and B get into the final dictionary 'newdict'.
newdict.update(A)
newdict.update(B)

# Iterate through each key of A.
for i in A.keys():

    # If same key exist on B, its values from A and B will add together and
    # get included in the final dictionary 'newdict'.
    try:
        addition = A[i] + B[i]
        newdict[i] = addition

    # If current key does not exist in dictionary B, it will give a KeyError,
    # catch it and continue looping.
    except KeyError:
        continue

EDIT: thanks to jerzyk for his improvement suggestions.

What you could do is have the selected attribute on the <select> tag be an attribute of this.state that you set in the constructor. That way, the initial value you set (the default) and when the dropdown changes you need to change your state.

constructor(){
  this.state = {
    selectedId: selectedOptionId
  }
}

dropdownChanged(e){
  this.setState({selectedId: e.target.value});
}

render(){
  return(
    <select value={this.selectedId} onChange={this.dropdownChanged.bind(this)}>
      {option_id.map(id =>
        <option key={id} value={id}>{options[id].name}</option>
      )}
    </select>
  );
}

You are trying to use . as a . not as the wildcard for any character. Use \. instead to indicate a period.

If document.write('<\script ...') isn't working, try document.createElement('script')...

Other than that, you should be worried about the type of website you're making - do you really think its a good idea to include .js files from .js files?

I know this is an old thread, but I like my own plugin that can cycle through whitespace modes (none, selection, and all) via a single shortcut. It also provides menu items under a View | Whitespace menu.

Hopefully people will find this useful - it is used by a lot of people :)

I was just looking for this... By using David's answer, I used a span and gave it some padding (height won't work + top margin issue)... Works like a charm;

I had an empty repo on GitHub with only the LICENSE file and a single commit locally. What worked was:

$ git fetch
$ git merge --allow-unrelated-histories
Merge made by the 'recursive' strategy.
 LICENSE | 21 +++++++++++++++++++++
 1 file changed, 21 insertions(+)
 create mode 100644 LICENSE

Also before merge you may want to:

$ git branch --set-upstream-to origin/master
Branch 'master' set up to track remote branch 'master' from 'origin'.

There is an hard limit on how much data can be stored in a single row of a mysql table, regardless of the number of columns or the individual column length.

As stated in the OFFICIAL DOCUMENTATION

The maximum row size constrains the number (and possibly size) of columns because the total length of all columns cannot exceed this size. For example, utf8 characters require up to three bytes per character, so for a CHAR(255) CHARACTER SET utf8 column, the server must allocate 255 × 3 = 765 bytes per value. Consequently, a table cannot contain more than 65,535 / 765 = 85 such columns.

Storage for variable-length columns includes length bytes, which are assessed against the row size. For example, a VARCHAR(255) CHARACTER SET utf8 column takes two bytes to store the length of the value, so each value can take up to 767 bytes.

Why are you combining GET and POST? Use one or the other.

$.ajax({
    type: 'post',
    data: {
        timestamp: timestamp,
        uid: uid
        ...
    }
});

php:

$uid =$_POST['uid'];

Or, just format your request properly (you're missing the ampersands for the get parameters).

url:"getdata.php?timestamp="+timestamp+"&uid="+id+"&uname="+name,

Try this:

USE master

        boolean result = !visible;
        System.out.println(result);

You have to use double-doublequotes to escape double-quotes within a verbatim string.

Request.QueryString["pID"];

Here Request is a object that retrieves the values that the client browser passed to the server during an HTTP request and QueryString is a collection is used to retrieve the variable values in the HTTP query string.

You will not only have to use an asp.net page but

If using the Entity Framework or LinqToSql (if using partial classes) move the data into a separate project, the report designer cannot see the classes.

Move the reports to another project/dll, VS10 has bugs were asp.net projects cannot see object datasources in web apps. Then stream the reports from the dll into your mvc projects aspx page.

This applies for mvc and webform projects. Using sql reports in the local mode is not a pleasent development experience. Also watch your webserver memory if exporting large reports. The reportviewer/export is very poorly designed.

The String.compareTo(..) method performs lexicographical comparison. Lexicographically == alphebetically.

You can include the hidden directories by going back a directory and doing:

cd ..

Assuming the directory you wanted to gzip was called workspace.

You need to delete your old db folder and recreate new one. It will resolve your issue.

Well, I believe it's an "Old but Gold" question. The answer is: "It depends!". The performances are such a delicate subject that it would be too much silly to say: "Never use subqueries, always join". In the following links, you'll find some basic best practices that I have found to be very helpful:

• Optimizing Subqueries
• Optimizing Subqueries with Semijoin Transformations
• Rewriting Subqueries as Joins

I have a table with 50000 elements, the result i was looking for was 739 elements.

My query at first was this:

SELECT  p.id,
    p.fixedId,
    p.azienda_id,
    p.categoria_id,
    p.linea,
    p.tipo,
    p.nome
FROM prodotto p
WHERE p.azienda_id = 2699 AND p.anno = (
    SELECT MAX(p2.anno) 
    FROM prodotto p2 
    WHERE p2.fixedId = p.fixedId 
)

and it took 7.9s to execute.

My query at last is this:

SELECT  p.id,
    p.fixedId,
    p.azienda_id,
    p.categoria_id,
    p.linea,
    p.tipo,
    p.nome
FROM prodotto p
WHERE p.azienda_id = 2699 AND (p.fixedId, p.anno) IN
(
    SELECT p2.fixedId, MAX(p2.anno)
    FROM prodotto p2
    WHERE p.azienda_id = p2.azienda_id
    GROUP BY p2.fixedId
)

and it took 0.0256s

Good SQL, good.

You are doing everything right by using a to_date function and specifying the time. The time is there in the database. The trouble is just that when you select a column of DATE datatype from the database, the default format mask doesn't show the time. If you issue a

alter session set nls_date_format = 'dd/MON/yyyy hh24:mi:ss'

or something similar including a time component, you will see that the time successfully made it into the database.

The documentation on counting says that for group_by queries it is better to use func.count():

from sqlalchemy import func
session.query(Table.column, func.count(Table.column)).group_by(Table.column).all()

If buttonSearch has no code, and only action is to return dialog result then:

    private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
            DialogResult = DialogResult.OK;
    }

The values can be retrieved during the parsing:

var yahoo = [], j = `[{"name":"Lenovo Thinkpad 41A4298","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41A2222","website":"google"},_x000D_

By using $(SDIR)/%.h as a prerequisite for $(ODIR)/%.o, this forced make to look in source-package directories for source code instead of looking in the same folder as the object file.

I hope this helps some people. Let me know if you see anything wrong with what I've provided.

BTW: As you may see from my last comment, clean is not being called and I am not sure why. Any ideas?

try {
    Desktop.getDesktop().browse(new URL("http://www.google.com").toURI());
} catch (Exception e) {}

note: you have to include necessary imports from java.net

holder.checkbox.setTag(row_id);

and

holder.checkbox.setOnClickListener( new OnClickListener() {

                @Override
                public void onClick(View v) {
                    CheckBox c = (CheckBox) v;

                    int row_id = (Integer) v.getTag();

                    checkboxes.put(row_id, c.isChecked());


                }
        });

Default arguments must be specified with the first occurrence of the function name—typically, in the function prototype. If the function prototype is omitted because the function definition also serves as the prototype, then the default arguments should be specified in the function header.

In most cases the solution of CD.. will work perfectly fine. However I had a bit more twisted situation:

 @(String.IsNullOrEmpty(Model.MaidenName) ? " " : Model.MaidenName)

This would print me "&nbsp;" in my page, respectively generate the source  . Now there is a function Html.Raw(" ") which is supposed to let you write source code, except in this constellation it throws a compiler error:

Compiler Error Message: CS0173: Type of conditional expression cannot be determined because there is no implicit conversion between 'System.Web.IHtmlString' and 'string'

So I ended up writing a statement like the following, which is less nice but works even in my case:

@if (String.IsNullOrEmpty(Model.MaidenName)) { @Html.Raw(" ") } else { @Model.MaidenName } 

Note: interesting thing is, once you are inside the curly brace, you have to restart a Razor block.

I faced a similar issue where XML was containing control characters. After looking into the code, I found that a deprecated class,StringBufferInputStream, was used for reading string content.

http://docs.oracle.com/javase/7/docs/api/java/io/StringBufferInputStream.html

This class does not properly convert characters into bytes. As of JDK 1.1, the preferred way to create a stream from a string is via the StringReader class.

I changed it to ByteArrayInputStream and it worked fine.

$.ajax({
        url: 'http://url.of.my.server/submit',
        dataType: "jsonp",
        jsonp: 'callback',
        jsonpCallback: 'jsonp_callback'
    });

jsonp is the querystring parameter name that is defined to be acceptable by the server while the jsonpCallback is the javascript function name to be executed at the client.
When you use such url:

url: 'http://url.of.my.server/submit?callback=?'

the question mark ? at the end instructs jQuery to generate a random function while the predfined behavior of the autogenerated function will just invoke the callback -the sucess function in this case- passing the json data as a parameter.

$.ajax({
        url: 'http://url.of.my.server/submit?callback=?',
        success: function (data, status) {
            mySurvey.closePopup();
        },
        error: function (xOptions, textStatus) {
            mySurvey.closePopup();
        }
    });

The same goes here if you are using $.getJSON with ? placeholder it will generate a random function while the predfined behavior of the autogenerated function will just invoke the callback:

$.getJSON('http://url.of.my.server/submit?callback=?',function(data){
//process data here
});

You can use hidden frame, load the file in there and parse its contents.

HTML:

<iframe id="frmFile" src="test.txt" onload="LoadFile();" style="display: none;"></iframe>

JavaScript:

<script type="text/javascript">
function LoadFile() {
    var oFrame = document.getElementById("frmFile");
    var strRawContents = oFrame.contentWindow.document.body.childNodes[0].innerHTML;
    while (strRawContents.indexOf("\r") >= 0)
        strRawContents = strRawContents.replace("\r", "");
    var arrLines = strRawContents.split("\n");
    alert("File " + oFrame.src + " has " + arrLines.length + " lines");
    for (var i = 0; i < arrLines.length; i++) {
        var curLine = arrLines[i];
        alert("Line #" + (i + 1) + " is: '" + curLine + "'");
    }
}
</script>

Note: in order for this to work in Chrome browser, you should start it with the --allow-file-access-from-files flag. _credit.

I had the same issue and solved it by closing the response at the end of the method:

try {
    // make the request and get the entity 
} catch(final Exception e) {
    // handle the exception
} finally {
    if(response != null) {
        response.close();
    }
}

Steve Ebersole & other members,
Would you kindly explain the reason for an id with a larger gap(by default 50)? I am using Hibernate 4.2.15 and found the following code in org.hibernate.id.enhanced.OptimizerFactory cass.

if ( lo > maxLo ) {
   lastSourceValue = callback.getNextValue();
   lo = lastSourceValue.eq( 0 ) ? 1 : 0;
   hi = lastSourceValue.copy().multiplyBy( maxLo+1 ); 
}  
value = hi.copy().add( lo++ );

Whenever it hits the inside of the if statement, hi value is getting much larger. So, my id during the testing with the frequent server restart generates the following sequence ids:
1, 2, 3, 4, 19, 250, 251, 252, 400, 550, 750, 751, 752, 850, 1100, 1150.

I know you already said it didn't conflict with the spec, but I believe this will be very unexpected situation for most developers.

Anyone's input will be much helpful.

Jihwan

UPDATE: ne1410s: Thanks for the edit.
cfrick: OK. I will do that. It was my first post here and wasn't sure how to use it.

Now, I understood better why maxLo was used for two purposes: Since the hibernate calls the DB sequence once, keep increase the id in Java level, and saves it to the DB, the Java level id value should consider how much was changed without calling the DB sequence when it calls the sequence next time.

For example, sequence id was 1 at a point and hibernate entered 5, 6, 7, 8, 9 (with allocationSize = 5). Next time, when we get the next sequence number, DB returns 2, but hibernate needs to use 10, 11, 12... So, that is why "hi = lastSourceValue.copy().multiplyBy( maxLo+1 )" is used to get a next id 10 from the 2 returned from the DB sequence. It seems only bothering thing was during the frequent server restart and this was my issue with the larger gap.

So, when we use the SEQUENCE ID, the inserted id in the table will not match with the SEQUENCE number in DB.

Actually, all the other answers have flaws. The most reliable way is:

IF "%~1"=="-b" (GOTO SPECIFIC) ELSE (GOTO UNKNOWN)

Detailed Explanation:

Using "%1"=="-b" will flat out crash if passing argument with spaces and quotes. This is the least reliable method.

IF "%1"=="-b" (GOTO SPECIFIC) ELSE (GOTO UNKNOWN)

C:\> run.bat "a b"

b""=="-b" was unexpected at this time.

Using [%1]==[-b] is better because it will not crash with spaces and quotes, but it will not match if the argument is surrounded by quotes.

IF [%1]==[-b] (GOTO SPECIFIC) ELSE (GOTO UNKNOWN)

C:\> run.bat "-b"

(does not match, and jumps to UNKNOWN instead of SPECIFIC)

Using "%~1"=="-b" is the most reliable. %~1 will strip off surrounding quotes if they exist. So it works with and without quotes, and also with no args.

IF "%~1"=="-b" (GOTO SPECIFIC) ELSE (GOTO UNKNOWN)

C:\> run.bat
C:\> run.bat -b
C:\> run.bat "-b"
C:\> run.bat "a b"

(all of the above tests work correctly)

These things helped me

1. Go to proxy -> SSL proxy settings -> Add
2. Add your site name here and give port number as 8888

3. Right click on your site name on the left panel and choose "Enable SSL Proxying"

Hope this helps someone out there.

the different log levels are helpful for tools, whose can anaylse you log files. Normally a logfile contains lots of information. To avoid an information overload (or here an stackoverflow^^) you can use the log levels for grouping the information.

Because timedelta is defined like:

class datetime.timedelta([days,] [seconds,] [microseconds,] [milliseconds,] [minutes,] [hours,] [weeks])

All arguments are optional and default to 0.

You can easily say "Three days and four milliseconds" with optional arguments that way.

>>> datetime.timedelta(days=3, milliseconds=4)
datetime.timedelta(3, 0, 4000)
>>> datetime.timedelta(3, 0, 0, 4) #no need for that.
datetime.timedelta(3, 0, 4000)

And for str casting, it returns a nice formatted value instead of __repr__ to improve readability. From docs:

str(t) Returns a string in the form [D day[s], ][H]H:MM:SS[.UUUUUU], where D is negative for negative t. (5)

>>> datetime.timedelta(seconds = 42).__repr__()
'datetime.timedelta(0, 42)'
>>> datetime.timedelta(seconds = 42).__str__()
'0:00:42'

Checkout documentation:

http://docs.python.org/library/datetime.html#timedelta-objects

It is actually very easy to do this using the "set" and "get" methods available on an express object.

Example as follows, say you have a variable called config with your configuration related stuff that you want to be available in other places:

In app.js:

var config = require('./config');

app.configure(function() {
  ...
  app.set('config', config); 
  ...
}

In routes/index.js

exports.index = function(req, res){
  var config = req.app.get('config');
  // config is now available
  ...
}

In addition to the accepted answer you can use this if you want to group by multiple columns:

<ul ng-repeat="(key, value) in players | groupBy: '[team,name]'">

If using PhpStorm 2019 and higher

File > Settings > Editor > General

There is'Soft-warp files' input under the 'Soft Warps' Header.

*.md; *.txt; *.rst; .adoc;

Add the file types to this field in which files you want them to be used.

*.md; *.txt; *.rst; .adoc;.php;*.js

Initializing a vector having struct, class or Union can be done this way

std::vector<SomeStruct> someStructVect(length);
memset(someStructVect.data(), 0, sizeof(SomeStruct)*length);

Easier than the above is

var today = new Date().toISOString().substring(0,10); # "2013-12-31"

try this,

$("document").ready(function(){

$("your id here").trigger("click");
});

You could use a literal eval:

>>> ast.literal_eval('0xdeadbeef')
3735928559

Or just specify the base as argument to int:

>>> int('deadbeef', 16)
3735928559

A trick that is not well known, if you specify the base 0 to int, then Python will attempt to determine the base from the string prefix:

>>> int("0xff", 0)
255
>>> int("0o644", 0)
420
>>> int("0b100", 0)
4
>>> int("100", 0)
100

In addition to SG's answer, you can also use the Decimal module:

from decimal import Decimal
x = str(Decimal(1) / Decimal(10000))

# x is a string '0.0001'

Also you can try to formulate your answer in the form of a SELECT CASE Statement. You can then later create simple if then's that use your results if needed as you have narrowed down the possibilities.

SELECT @Result =   
CASE @inputParam   
WHEN 1 THEN 1   
WHEN 2 THEN 2   
WHEN 3 THEN 1   
ELSE 4   
END  

IF @Result = 1   
BEGIN  
...  
END  

IF @Result = 2   
BEGIN   
....  
END  

IF @Result = 4   
BEGIN   
//Error handling code   
END   

You could use this CMD in your Dockerfile:

CMD exec /bin/bash -c "trap : TERM INT; sleep infinity & wait"

This will keep your container alive until it is told to stop. Using trap and wait will make your container react immediately to a stop request. Without trap/wait stopping will take a few seconds.

For busybox based images (used in alpine based images) sleep does not know about the infinity argument. This workaround gives you the same immediate response to a docker stop like in the above example:

CMD exec /bin/sh -c "trap : TERM INT; sleep 9999999999d & wait"

I discovered the joy of anaconda: https://www.continuum.io/downloads

C:> conda create -n tensorflow1.1 python=3.5
C:> activate tensorflow1.1
(tensorflow1.1) 
C:> pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.1.0-cp35-cp35m-win_amd64.whl

voila, a virtual environment is created.

I think one error in the original code might have been that it had:

$message = echo getRequestURI();

instead of:

$message = getRequestURI();

(The code has since been edited though.)

A dict is a hash table, so it is really fast to find the keys. So between dict and list, dict would be faster. But if you don't have a value to associate, it is even better to use a set. It is a hash table, without the "table" part.

EDIT: for your new question, YES, a set would be better. Just create 2 sets, one for sequences ended in 1 and other for the sequences ended in 89. I have sucessfully solved this problem using sets.

Try Ehcache? It allows you to plug in your own caching expiry algorithms so you could control your peek functionality.

You can serialize to disk, database, across a cluster etc...

Why do you use new Date instead of a static UTC string?

    function clearListCookies(){
    var cookies = document.cookie.split(";");
        for (var i = 0; i < cookies.length; i++){   
            var spcook =  cookies[i].split("=");
            document.cookie = spcook[0] + "=;expires=Thu, 21 Sep 1979 00:00:01 UTC;";                                
        }
    }

Here's another 2020 solution, inspired by @Sandeep's. Using the MinimalSplitDateTimeMultiWidget found in this gist, in our Form as below, we can use modern browser date and time selectors (via eg 'type': 'date'). We don't need any JS.

class EditAssessmentBaseForm(forms.ModelForm):
    class Meta:
        model = Assessment
        fields = '__all__'

    begin = DateTimeField(widget=MinimalSplitDateTimeMultiWidget())

This works:

wget -m -np -c --no-check-certificate -R "index.html*" "https://the-eye.eu/public/AudioBooks/Edgar%20Allan%20Poe%20-%2"

So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.

 protected void onCreate(Bundle savedInstanceState) {     setContentView(R.layout.my_layout);     Bitmap bitmap = getIntent().getParcelableExtra("image");     ImageView imageView = (ImageView) findViewById(R.id.imageview);     imageView.setImageBitmap(bitmap);  } 

Import: You must write columns in INSERT statement

INSERT INTO TABLE
SELECT * FROM    

Is not correct.

Insert into Table(Field1,...)
Select (Field1,...) from TABLE

Is correct

private void selectDOB() {

    final Calendar calendar = Calendar.getInstance();
    mYear = calendar.get(Calendar.YEAR);
    mDay = calendar.get(Calendar.DATE);
    mMonth = calendar.get(Calendar.MONTH);

    DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
        @SuppressLint("LongLogTag")
        @Override
        public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
            strDateOfBirth = (month + 1) + "-" + dayOfMonth + "-" + year;

            //********************** check and set date with append 0 at starting***************************
            if (dayOfMonth < 10) {
                strNewDay = "0" + dayOfMonth;
            } else {
                strNewDay = dayOfMonth + "";
            }
            if (month + 1 < 10) {
                strNewMonth = "0" + (month + 1);
            } else {
                strNewMonth = (month + 1) + "";
            }

            Log.e("strnewDay *****************", strNewDay + "");
            Log.e("strNewMonth *****************", strNewMonth + "");

            //    etDateOfBirth.setText(dayOfMonth + " / " + (month + 1) + " / " + year);
            etDateOfBirth.setText(strNewDay + " / " + strNewMonth + " / " + year);

            Log.e("strDateOfBirth *******************", strDateOfBirth + "");

        }
    }, mYear, mMonth, mDay);

    datePickerDialog.show();

    //*************** input date of birth must be greater than or equal to 18 ************************************

    Calendar maxDate = Calendar.getInstance();
    maxDate.set(Calendar.DAY_OF_MONTH, mDay);
    maxDate.set(Calendar.MONTH, mMonth);
    maxDate.set(Calendar.YEAR, mYear - 18);
    datePickerDialog.getDatePicker().setMaxDate(maxDate.getTimeInMillis());

    //*************** input date of birth must be less than today date ************************************
    //   datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());

}

Often when you need to show so many points on the map, you'd be better off using the server-side approach, this article explains when to use each:

Geocoding Strategies: https://developers.google.com/maps/articles/geocodestrat

The client-side limit is not exactly "10 requests per second", and since it's not explained in the API docs I wouldn't rely on its behavior.

In my case the issue was not resolved because i did not restart my system. Please make sure you do restart your system.

You can do it like this:

postData[postData.length] = { name: "variable_name", value: variable_value };

//first find out the removed ones

List removedList = new ArrayList();
for(Object a: list){
    if(a.getXXX().equalsIgnoreCase("AAA")){
        logger.info("this is AAA........should be removed from the list ");
        removedList.add(a);

    }
}

list.removeAll(removedList);

Unions are great. One clever use of unions I've seen is to use them when defining an event. For example, you might decide that an event is 32 bits.

Now, within that 32 bits, you might like to designate the first 8 bits as for an identifier of the sender of the event... Sometimes you deal with the event as a whole, sometimes you dissect it and compare it's components. unions give you the flexibility to do both.

union Event
{
  unsigned long eventCode;
  unsigned char eventParts[4];
};

Thanks, I didn't have the idea of an UPDATE with INNER JOIN.

In the original query, the mistake was to name the subquery, which must return a value and can't therefore be aliased.

UPDATE Competition
SET Competition.NumberOfTeams =
(SELECT count(*) -- no column alias
  FROM PicksPoints
  WHERE UserCompetitionID is not NULL
  -- put the join condition INSIDE the subquery :
  AND CompetitionID =  Competition.CompetitionID
  group by CompetitionID
) -- no table alias

should do the trick for every record of Competition.

To be noticed :

The effect is NOT EXACTLY the same as the query proposed by mellamokb, which won't update Competition records with no corresponding PickPoints.

Since SELECT id, COUNT(*) GROUP BY id will only count for existing values of ids,

whereas a SELECT COUNT(*) will always return a value, being 0 if no records are selected.

This may, or may not, be a problem for you.

0-aware version of mellamokb query would be :

Update Competition as C
LEFT join (
  select CompetitionId, count(*) as NumberOfTeams
  from PicksPoints as p
  where UserCompetitionID is not NULL
  group by CompetitionID
) as A on C.CompetitionID = A.CompetitionID
set C.NumberOfTeams = IFNULL(A.NumberOfTeams, 0)

In other words, if no corresponding PickPoints are found, set Competition.NumberOfTeams to zero.

Maybe you want unpack elements of array, I don't know if I got it, but below a example:

def my_func(*args):
    for a in args:
        print a

my_func(*[1,2,3,4])
my_list = ['a','b','c']
my_func(*my_list)

You can nest table-cell directly within table. You muslt have a table. Starting eith table-row does not work. Try it with this HTML:

<html>
  <head>
    <style type="text/css">
.table {
  display: table;
  width: 100%;
}
.tr {
  display: table-row;
  width: 100%;
}
.td {
  display: table-cell;
}
    </style>
  </head>
  <body>

    <div class="table">
      <div class="tr">
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
      </div>
    </div>

      <div class="tr">
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
      </div>

    <div class="table">
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
    </div>

  </body>
</html>

Thread thread = new Thread(() -> {

Your custom code goes instead of the ...

The @ symbol denotes an annotation type definition.

That means it is not really an interface, but rather a new annotation type -- to be used as a function modifier, such as @override.

See this javadocs entry on the subject.

There's no "else if". You have the following:

if (condition)
    statement or block

Or:

if (condition)
    statement or block
else
    statement or block

In the first case, the statement or block is executed if the condition is true (different than 0). In the second case, if the condition is true, the first statement or block is executed, otherwise the second statement or block is executed.

So, when you write "else if", that's an "else statement", where the second statement is an if statement. You might have problems if you try to do this:

if (condition)
    if (condition)
        statement or block
else
    statement or block

The problem here being you want the "else" to refer to the first "if", but you are actually referring to the second one. You fix this by doing:

if (condition)
{
    if (condition)
        statement or block
} else
    statement or block

There was same problem in my Colleague's code. This sounds as your Radio Group is not properly set with your Radio Buttons. This is the reason you can multi-select the radio buttons. I tried many things, finally i did a trick which is wrong actually, but works fine.

for ( int i = 0 ; i < myCount ; i++ )
{
    if ( i != k )
    {
        System.out.println ( "i = " + i );
        radio1[i].setChecked(false);
    }
}

Here I set one for loop, which checks for the available radio buttons and de-selects every one except the new clicked one. try it.

You better use the override onPrepareOptionsMenu

menu.Clear ();
   if (TabActual == TabSelec.Anuncio)
   {
       menu.Add(10, 11, 0, "Crear anuncio");
       menu.Add(10, 12, 1, "Modificar anuncio");
       menu.Add(10, 13, 2, "Eliminar anuncio");
       menu.Add(10, 14, 3, "Actualizar");
   }
   if (TabActual == TabSelec.Fotos)
   {
       menu.Add(20, 21, 0, "Subir foto");
       menu.Add(20, 22, 1, "Actualizar");
   }
   if (TabActual == TabSelec.Comentarios)
   {
       menu.Add(30, 31, 0, "Actualizar");
   }

Here an example

To offer an update on the situation on Q2 of 2017.

A new CSS3 display property is available in Firefox 53, Chrome 58 and Opera 45.

.clearfix {
   display: flow-root;
}

Check the availability for any browser here: http://caniuse.com/#feat=flow-root

The element (with a display property set to flow-root) generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents.

Meaning that if you use a parent div containing one or several floating children, this property is going to ensure the parent encloses all of its children. Without any need for a clearfix hack. On any children, nor even a last dummy element (if you were using the clearfix variant with :before on the last children).

.container {_x000D_
  display: flow-root;_x000D_
  background-color: Gainsboro;_x000D_
}_x000D_
_x000D_
.item {_x000D_
  border: 1px solid Black;_x000D_
  float: left;_x000D_
}_x000D_
_x000D_
.item1 {  _x000D_
  height: 120px;_x000D_
  width: 120px;_x000D_
}_x000D_
_x000D_
.item2 {  _x000D_
  height: 80px;_x000D_
  width: 140px;_x000D_
  float: right;_x000D_
}_x000D_
_x000D_
.item3 {  _x000D_
  height: 160px;_x000D_
  width: 110px;_x000D_
}

<div class="container">_x000D_
  This container box encloses all of its floating children._x000D_
  <div class="item item1">Floating box 1</div>_x000D_
  <div class="item item2">Floating box 2</div> _x000D_
  <div class="item item3">Floating box 3</div>  _x000D_
</div>

Consider supplementing, not replacing, MSTest with another testing framework. You can keep Visual Studio MSTest integration while getting the benefits of a more full-featured testing framework.

For example, i use xUnit with MSTest. Add a reference to the xUnit.dll assembly, and just do something like this. Suprisingly, it just works!

using Microsoft.VisualStudio.TestTools.UnitTesting;
using Assert = Xunit.Assert;  // <-- Aliasing the Xunit namespace is key

namespace TestSample
{
    [TestClass]
    public class XunitTestIntegrationSample
    {
        [TestMethod]
        public void TrueTest()
        {
            Assert.True(true);  // <-- this is the Xunit.Assert class
        }

        [TestMethod]
        public void FalseTest()
        {
            Assert.False(true);
        }
    }
}

For those who are learning node/express (just like me): do not use wildcard routing if possible!

I also wanted to implement the routing for GET /users/:id/whatever using wildcard routing. This is how I got here.

More info: https://blog.praveen.science/wildcard-routing-is-an-anti-pattern/

For checking type conversions in version 3, you can go to their github and check into the different liquibase types and check the method toDatabaseDataType. For example, for Boolean, you can check here:

https://github.com/liquibase/liquibase/blob/master/liquibase-core/src/main/java/liquibase/datatype/core/BooleanType.java

For version 2.0.x, the conversion seems to be into database specific classes. For example, for Mysql:

https://github.com/liquibase/liquibase/blob/2_0_x/liquibase-core/src/main/java/liquibase/database/typeconversion/core/MySQLTypeConverter.java

You can see the list of color schemes under /usr/share/vim/vimNN/colors (with NN being the version, e.g. vim74 for vim 7.4).

This is explained here.

On the linux servers I use via ssh, TAB prints ^I and CTRLd prints ^D.

I resolved by following the below steps

1.Right click on command Prompt 2.Run as administrator 3.type npm install -g @angular/cli

In general, CSS properties are converted to JavaScript by making them camelCase without any dashes. So background-color becomes backgroundColor.

function setColor(element, color)
{
    element.style.backgroundColor = color;
}

// where el is the concerned element
var el = document.getElementById('elementId');
setColor(el, 'green');

Prior to PHP 7 type hinting can only be used to force the types of objects and arrays. Scalar types are not type-hintable. In this case an object of the class string is expected, but you're giving it a (scalar) string. The error message may be funny, but it's not supposed to work to begin with. Given the dynamic typing system, this actually makes some sort of perverted sense.

You can only manually "type hint" scalar types:

function foo($string) {
    if (!is_string($string)) {
        trigger_error('No, you fool!');
        return;
    }
    ...
}

declare @nReturn int = 0 EXEC @nReturn = Stored Procedures

More accurately, your mod1 and lib directories are not modules, they are packages. The file mod11.py is a module.

Python does not automatically import subpackages or modules. You have to explicitly do it, or "cheat" by adding import statements in the initializers.

>>> import lib
>>> dir(lib)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']
>>> import lib.pkg1
>>> import lib.pkg1.mod11
>>> lib.pkg1.mod11.mod12()
mod12

An alternative is to use the from syntax to "pull" a module from a package into you scripts namespace.

>>> from lib.pkg1 import mod11

Then reference the function as simply mod11.mod12().

Let's try this

select convert(varchar, getdate(), 108) 

Just try a few moment ago

take a look at the following examples

http://threejs.org/examples/#misc_controls_orbit

http://threejs.org/examples/#misc_controls_trackball

there are other examples for different mouse controls, but both of these allow the camera to rotate around a point and zoom in and out with the mouse wheel, the main difference is OrbitControls enforces the camera up direction, and TrackballControls allows the camera to rotate upside-down.

All you have to do is include the controls in your html document

<script src="js/OrbitControls.js"></script>

and include this line in your source

controls = new THREE.OrbitControls( camera, renderer.domElement );

Thanks Jason Rogers's answer first.

In Android && cpp should be this:

const char *nativeString = env->GetStringUTFChars(javaString, nullptr);

// use your string

env->ReleaseStringUTFChars(javaString, nativeString);

Can fix this errors:

1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'

2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'

3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'

4.add "env->DeleteLocalRef(nativeString);" at end.

The solution of Brad Smith worked for me, but I also had to remove the CODE_SIGN_IDENTITY field to make it work.

You can also use pandas.Series.isin although it's a little bit longer than 'a' in s.values:

In [2]: s = pd.Series(list('abc'))

In [3]: s
Out[3]: 
0    a
1    b
2    c
dtype: object

In [3]: s.isin(['a'])
Out[3]: 
0    True
1    False
2    False
dtype: bool

In [4]: s[s.isin(['a'])].empty
Out[4]: False

In [5]: s[s.isin(['z'])].empty
Out[5]: True

But this approach can be more flexible if you need to match multiple values at once for a DataFrame (see DataFrame.isin)

>>> df = DataFrame({'A': [1, 2, 3], 'B': [1, 4, 7]})
>>> df.isin({'A': [1, 3], 'B': [4, 7, 12]})
       A      B
0   True  False  # Note that B didn't match 1 here.
1  False   True
2   True   True

They are related values, and kept consistent by the property setter/getter methods (and using the fact that frame is a purely synthesized value, not backed by an actual instance variable).

The main equations are:

frame.origin = center - bounds.size / 2

(which is the same as)

center = frame.origin + bounds.size / 2

(and there’s also)

frame.size = bounds.size

That's not code, just equations to express the invariant between the three properties. These equations also assume your view's transform is the identity, which it is by default. If it's not, then bounds and center keep the same meaning, but frame can change. Unless you're doing non-right-angle rotations, the frame will always be the transformed view in terms of the superview's coordinates.

This stuff is all explained in more detail with a useful mini-library here:

http://bynomial.com/blog/?p=24

I improved on the solution that uses a regex by Pinhassi so it also handles the edge cases correctly. Before checking if the input is correct, first the final string is constructed as described by the android docs.

public class DecimalDigitsInputFilter implements InputFilter {

    private Pattern mPattern;

    private static final Pattern mFormatPattern = Pattern.compile("\\d+\\.\\d+");

    public DecimalDigitsInputFilter(int digitsBeforeDecimal, int digitsAfterDecimal) {
        mPattern = Pattern.compile(
            "^\\d{0," + digitsBeforeDecimal + "}([\\.,](\\d{0," + digitsAfterDecimal +
                "})?)?$");
    }

    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, 
                               int dstart, int dend) {

        String newString =
            dest.toString().substring(0, dstart) + source.toString().substring(start, end) 
            + dest.toString().substring(dend, dest.toString().length());

        Matcher matcher = mPattern.matcher(newString);
        if (!matcher.matches()) {
            return "";
        }
        return null;
    }
}

Usage:

editText.setFilters(new InputFilter[] {new DecimalDigitsInputFilter(5,2)});

In my case my only requirement is that the user input won't be interpreted as a relative link when placed in the href of an a tag and the answers here were either a bit OTT for that or allowed URLs not meeting my requirements, so this is what I'm going with:

^https?://.+$

The same thing could be achieved pretty easily without regex.

Yes, you can store images in the database, but it's not advisable in my opinion, and it's not general practice.

A general practice is to store images in directories on the file system and store references to the images in the database. e.g. path to the image,the image name, etc.. Or alternatively, you may even store images on a content delivery network (CDN) or numerous hosts across some great expanse of physical territory, and store references to access those resources in the database.

Images can get quite large, greater than 1MB. And so storing images in a database can potentially put unnecessary load on your database and the network between your database and your web server if they're on different hosts.

I've worked at startups, mid-size companies and large technology companies with 400K+ employees. In my 13 years of professional experience, I've never seen anyone store images in a database. I say this to support the statement it is an uncommon practice.

You will need to use JS to send the URL back with a variable in it such as: http://www.site.com/index.php?uid=1

by using something like this in JS:

window.location.href=”index.php?uid=1";

Then in the PHP code use $_GET:

$somevar = $_GET["uid"]; //puts the uid varialbe into $somevar

An other solution:

interface bar {
    length: number;
}

bars = [{
  length: 1
} as bar];

The above code didn't work for me. The following approach worked.

Create an Intent object with appropriate info and then check if the Intent is callable or not using the following function:

private boolean isCallable(Intent intent) {  
        List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent,   
        PackageManager.MATCH_DEFAULT_ONLY);  
        return list.size() > 0;  
}

Please use the following command,

cat /etc/bash.bashrc > ~/.bashrc

This will generate a new bashrc file with the default values. Please use vi ~/.bashrc to edit this file.

In the last statement you are converting the duration to time which also considers the timezone. I assume that your timezone is +530, so 5 hours and 30 minutes gets added to 30 minutes. You can do as given below.

var eventTime= 1366549200; // Timestamp - Sun, 21 Apr 2013 13:00:00 GMT
var currentTime = 1366547400; // Timestamp - Sun, 21 Apr 2013 12:30:00 GMT
var diffTime = eventTime - currentTime;
var duration = moment.duration(diffTime*1000, 'milliseconds');
var interval = 1000;

setInterval(function(){
  duration = moment.duration(duration - interval, 'milliseconds');
    $('.countdown').text(duration.hours() + ":" + duration.minutes() + ":" + duration.seconds())
}, interval);

Simply, Dictionary<TKey,TValue> is a generic type, allowing:

• static typing (and compile-time verification)
• use without boxing

If you are .NET 2.0 or above, you should prefer Dictionary<TKey,TValue> (and the other generic collections)

A subtle but important difference is that Hashtable supports multiple reader threads with a single writer thread, while Dictionary offers no thread safety. If you need thread safety with a generic dictionary, you must implement your own synchronization or (in .NET 4.0) use ConcurrentDictionary<TKey, TValue>.

Yes, you can even change it by triggering an event

<input type='text' name='pass'  onclick="(this.type='password')" />


<input type="text" placeholder="date" onfocusin="(this.type='date')" onfocusout="(this.type='text')">

I have done some investigation and sharing my results here,this may be useful for others.

First, we can check whether MockSetting option is turned ON

public static boolean isMockSettingsON(Context context) {
    // returns true if mock location enabled, false if not enabled.
    if (Settings.Secure.getString(context.getContentResolver(),
                                Settings.Secure.ALLOW_MOCK_LOCATION).equals("0"))
        return false;
    else
        return true;
}

Second, we can check whether are there other apps in the device, which are using android.permission.ACCESS_MOCK_LOCATION (Location Spoofing Apps)

public static boolean areThereMockPermissionApps(Context context) {
    int count = 0;

    PackageManager pm = context.getPackageManager();
    List<ApplicationInfo> packages =
        pm.getInstalledApplications(PackageManager.GET_META_DATA);

    for (ApplicationInfo applicationInfo : packages) {
        try {
            PackageInfo packageInfo = pm.getPackageInfo(applicationInfo.packageName,
                                                        PackageManager.GET_PERMISSIONS);

            // Get Permissions
            String[] requestedPermissions = packageInfo.requestedPermissions;

            if (requestedPermissions != null) {
                for (int i = 0; i < requestedPermissions.length; i++) {
                    if (requestedPermissions[i]
                        .equals("android.permission.ACCESS_MOCK_LOCATION")
                        && !applicationInfo.packageName.equals(context.getPackageName())) {
                        count++;
                    }
                }
            }
        } catch (NameNotFoundException e) {
            Log.e("Got exception " , e.getMessage());
        }
    }

    if (count > 0)
        return true;
    return false;
}

If both above methods, first and second are true, then there are good chances that location may be spoofed or fake.

Now, spoofing can be avoided by using Location Manager's API.

We can remove the test provider before requesting the location updates from both the providers (Network and GPS)

LocationManager lm = (LocationManager) getSystemService(LOCATION_SERVICE);

try {
    Log.d(TAG ,"Removing Test providers")
    lm.removeTestProvider(LocationManager.GPS_PROVIDER);
} catch (IllegalArgumentException error) {
    Log.d(TAG,"Got exception in removing test  provider");
}

lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, locationListener);

I have seen that removeTestProvider(~) works very well over Jelly Bean and onwards version. This API appeared to be unreliable till Ice Cream Sandwich.

Flutter Update: Use Geolocator and check Position object's isMocked property.

Side effect takes a function (which can also be a lambda function), so for simple cases you may use:

m = MagicMock(side_effect=(lambda x: x+1))

If you only want to animate the height of a view (from say 0 to a certain number) you could implement your own animation:

final View v = getTheViewToAnimateHere();
Animation anim=new Animation(){
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        super.applyTransformation(interpolatedTime, t);
        // Do relevant calculations here using the interpolatedTime that runs from 0 to 1
        v.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, (int)(30*interpolatedTime)));
    }};
anim.setDuration(500);
v.startAnimation(anim);

Here is my take on that one...

function copy(text) {
    var input = document.createElement('input');
    input.setAttribute('value', text);
    document.body.appendChild(input);
    input.select();
    var result = document.execCommand('copy');
    document.body.removeChild(input);
    return result;
 }

@korayem: Note that using html input field won't respect line breaks \n and will flatten any text into a single line.

As mentioned by @nikksan in the comments, using textarea will fix the problem as follows:

function copy(text) {
    var input = document.createElement('textarea');
    input.innerHTML = text;
    document.body.appendChild(input);
    input.select();
    var result = document.execCommand('copy');
    document.body.removeChild(input);
    return result;
}

-fix- because you want to change from radians to degrees, it is actually rad=deg * math.pi /180 and not deg*180/math.pi

import math
x=1                # in deg
x = x*math.pi/180  # convert to rad
y = math.cos(x)    # calculate in rad

print y

in 1 line it can be like this

y=math.cos(1*math.pi/180)

400 is the best choice in both cases. If you want to further clarify the error you can either change the Reason Phrase or include a body to explain the error.

412 - Precondition failed is used for conditional requests when using last-modified date and ETags.

403 - Forbidden is used when the server wishes to prevent access to a resource.

The only other choice that is possible is 422 - Unprocessable entity.

Bootstrap 3

Here is a working left sidebar example:

http://bootply.com/90936 (similar to the Bootstrap docs)

The trick is using the affix component along with some CSS to position it:

  #sidebar.affix-top {
    position: static;
    margin-top:30px;
    width:228px;
  }

  #sidebar.affix {
    position: fixed;
    top:70px;
    width:228px;
  }

EDIT- Another example with footer and affix-bottom

Bootstrap 4

The Affix component has been removed in Bootstrap 4, so to create a sticky sidebar, you can use a 3rd party Affix plugin like this Bootstrap 4 sticky sidebar example, or use the sticky-top class is explained in this answer.

Related: Create a responsive navbar sidebar "drawer" in Bootstrap 4?

If you are using Linux OS:

1. Remove matplotlib==1.3.1 from requirements.txt
2. Try to install with sudo apt-get install python-matplotlib
3. Run pip install -r requirements.txt (Python 2), or pip3 install -r requirements.txt (Python 3)
4. pip freeze > requirements.txt

If you are using Windows OS:

1. python -m pip install -U pip setuptools
2. python -m pip install matplotlib

Try this, It will help.

I have used this in my project.

SELECT 
*
FROM
customer c
OUTER APPLY(SELECT top 1 * FROM purchase pi 
WHERE pi.customer_id = c.Id order by pi.Id desc) AS [LastPurchasePrice]

what about using the official API?

According to the API doc:

DESTROY: Removes the datepicker functionality completely. This will return the element back to its pre-init state.

Use:

$("#txtSearch").datepicker("destroy");

to restore the input to its normal behaviour and

$("#txtSearch").datepicker(/*options*/);

again to show the datapicker again.

getElementsByClassName returns HTMLCollection in modern browsers.

which is array-like object similar to arguments which is iteratable by for...of loop see below what MDN doc is saying about it:

The for...of statement creates a loop iterating over iterable objects, including: built-in String, Array, Array-like objects (e.g., arguments or NodeList), TypedArray, Map, Set, and user-defined iterables. It invokes a custom iteration hook with statements to be executed for the value of each distinct property of the object.

example

for (const element of document.getElementsByClassName("classname")){
   element.style.display="none";
}

After finding this StackOverflow question/answer

Complex type is getting null in a ApiController parameter

the [FromBody] attribute on the controller method needs to be [FromUri] since a GET does not have a body. After this change the "filter" complex object is passed correctly.

I guess this is essentially putting it in a string, but this avoids the rounding error:

import decimal

def display(x):
    digits = 15
    temp = str(decimal.Decimal(str(x) + '0' * digits))
    return temp[:temp.find('.') + digits + 1]

FOR NEOVIM

Due to problems with interactive calls (https://github.com/neovim/neovim/issues/1716), I am using this for neovim, based on Dr Beco's answer:

cnoremap w!! execute 'silent! write !SUDO_ASKPASS=`which ssh-askpass` sudo tee % >/dev/null' <bar> edit!

This will open a dialog using ssh-askpass asking for the sudo password.

In addition to the commonly known five characters [<, >, &, ", and '], I would also escape the vertical tab character (0x0B). It is valid UTF-8, but not valid XML 1.0, and even many libraries (including the highly portable (ANSI C) library libxml2) miss it and silently output invalid XML.

You can install scipy and numpy using their wheels.

First install wheel package if it's already not there...

pip install wheel

Just select the package you want from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy

Example: if you're running python3.5 32 bit on Windows choose scipy-0.18.1-cp35-cp35m-win_amd64.whl then it will automatically download.

Then go to the command line and change the directory to the downloads folder and install the above wheel using pip.

Example:

cd C:\Users\[user]\Downloads
pip install scipy-0.18.1-cp35-cp35m-win_amd64.whl

I had a similar problem in a large multi-module project with many dependencies among the modules. What worked for me, was to attempt to build separately from command line all the modules that failed to build within Android Studio. That gave me indications on resources missing in each project. From the project level in my console I did:

This provided me with a number of 'No resource found that matches the given name' errors, that weren't shown before, when I build the project as a whole.

Do you want something like the given fiddle!

I've tried all the possible solutions but nothing worked for local video bindings. I believe best solution would be to fix using jQuery if you still wants to use iframes.

$(document).ready(function () {
    var ownVideos = $("iframe");
    $.each(ownVideos, function (i, video) {                
        var frameContent = $(video).contents().find('body').html();
        if (frameContent) {
            $(video).contents().find('body').html(frameContent.replace("autoplay", ""));
        }
    });
});

Note: It'll find all the iframes on document ready and loop through each iframe contents and replace/remove autoplay attribute. This solution can be use anywhere in your project. If you would like to do for specific element then use the code under $.each function and replace $(video) with your iframe element id like $("#myIFrameId").

Use

string += '=' * (-len(string) % 4)  # restore stripped '='s

Credit goes to a comment somewhere here.

>>> import base64

>>> enc = base64.b64encode('1')

>>> enc
>>> 'MQ=='

>>> base64.b64decode(enc)
>>> '1'

>>> enc = enc.rstrip('=')

>>> enc
>>> 'MQ'

>>> base64.b64decode(enc)
...
TypeError: Incorrect padding

>>> base64.b64decode(enc + '=' * (-len(enc) % 4))
>>> '1'

An inner class has access to all members of the outer class, but it does not have an implicit reference to a parent class instance (unlike some weirdness with Java). So if you pass a reference to the outer class to the inner class, it can reference anything in the outer class instance.

Use the collapse argument to paste:

paste(a,collapse=" ")
[1] "aa bb cc"

If you are expecting 4 as output then try this:

char a[]={0x00,0xdc,0x01,0x04};

With so many answers already written, Here's my take.

With Angular 1.5.6 & ui-bootstrap 1.3.3 , just add this on the model & you are done.

ng-model-options="{timezone: 'UTC'}" 

Note: Use this only if you are concerned about the date being 1 day behind & not bothered with extra time of T00:00:00.000Z

Alternatively

with Pool() as pool: 
    pool.map(fits.open, [name + '.fits' for name in datainput])

Taken from http://en.wikipedia.org/wiki/Deadlock:

In concurrent computing, a deadlock is a state in which each member of a group of actions, is waiting for some other member to release a lock

A livelock is similar to a deadlock, except that the states of the processes involved in the livelock constantly change with regard to one another, none progressing. Livelock is a special case of resource starvation; the general definition only states that a specific process is not progressing.

A real-world example of livelock occurs when two people meet in a narrow corridor, and each tries to be polite by moving aside to let the other pass, but they end up swaying from side to side without making any progress because they both repeatedly move the same way at the same time.

Livelock is a risk with some algorithms that detect and recover from deadlock. If more than one process takes action, the deadlock detection algorithm can be repeatedly triggered. This can be avoided by ensuring that only one process (chosen randomly or by priority) takes action.

Adjust the sequence of your environment variable %path% to make sure jre 1.7 is the default one.

While T. Arboreus's answer might fix the issues with resolving 'archive.ubuntu.com', I think the last error you're getting says that it doesn't know about the packages php5-mcrypt and python-pip. Nevertheless, the reduced Dockerfile of you with just these two packages worked for me (using Debian 8.4 and Docker 1.11.0), but I'm not quite sure if that could be the case because my host system is different than yours.

FROM ubuntu:14.04

# Install dependencies
RUN apt-get update && apt-get install -y \
    php5-mcrypt \
    python-pip

However, according to this answer you should think about installing the python3-pip package instead of the python-pip package when using Python 3.x.

Furthermore, to make the php5-mcrypt package installation working, you might want to add the universe repository like it's shown right here. I had trouble with the add-apt-repository command missing in the Ubuntu Docker image so I installed the package software-properties-common at first to make the command available.

Splitting up the statements and putting apt-get update and apt-get install into one RUN command is also recommended here.

Oh and by the way, you actually don't need the -y flag at apt-get update because there is nothing that has to be confirmed automatically.

Finally:

FROM ubuntu:14.04

# Install dependencies
RUN apt-get update && apt-get install -y \
    software-properties-common
RUN add-apt-repository universe
RUN apt-get update && apt-get install -y \
    apache2 \
    curl \
    git \
    libapache2-mod-php5 \
    php5 \
    php5-mcrypt \
    php5-mysql \
    python3.4 \
    python3-pip

Remark: The used versions (e.g. of Ubuntu) might be outdated in the future.

Also We can use StopWatch class of Apache commons for measuring the time.

Sample code

org.apache.commons.lang.time.StopWatch sw = new org.apache.commons.lang.time.StopWatch();

System.out.println("getEventFilterTreeData :: Start Time : " + sw.getTime());
sw.start();

// Method execution code

sw.stop();
System.out.println("getEventFilterTreeData :: End Time : " + sw.getTime());

Since in your question you said it's a PHP script, maybe the best solution could be to simply add in your script:

ignore_user_abort(TRUE);

In this way even if wget terminates, the PHP script goes on being processed at least until it does not exceeds max_execution_time limit (ini directive: 30 seconds by default).

As per wget anyay you should not change its timeout, according to the UNIX manual the default wget timeout is 900 seconds (15 minutes), whis is much larger that the 5-6 minutes you need.

While the solutions here are workable, more recent technology has made for what I think is a better solution. CSS Grid Layout allows us to structure a more elegant solution.

The CSS below provides a 2-column "settings" structure, where the first column is expected to be a right-aligned label, followed by some content in the second column. More complicated content can be presented in the second column by wrapping it in a <div>.

[As a side-note: I use CSS to add the ':' that trails each label, as this is a stylistic element - my preference.]

/* CSS */_x000D_
_x000D_
div.settings {_x000D_
    display:grid;_x000D_
    grid-template-columns: max-content max-content;_x000D_
    grid-gap:5px;_x000D_
}_x000D_
div.settings label       { text-align:right; }_x000D_
div.settings label:after { content: ":"; }

<!-- HTML -->_x000D_
_x000D_
<div class="settings">_x000D_
    <label>Label #1</label>_x000D_
    <input type="text" />_x000D_
_x000D_
    <label>Long Label #2</label>_x000D_
    <span>Display content</span>_x000D_
_x000D_
    <label>Label #3</label>_x000D_
    <input type="text" />_x000D_
</div>

As Coli88 said, you should check the UINavigationBarDelegate protocol.

In a more general way, you can also use the - (void)viewWillDisapear:(BOOL)animated to perform custom work when the view retained by the currently visible view controller is about to disappear. Unfortunately, this would cover bother the push and the pop cases.

You must either wrap your collection in a list (new ArrayList(c)) or use c.toArray() since Collections have no notion of "index" or "order".

As with all date manipulation you have to use NSDateComponents and NSCalendar

NSDate *now = [NSDate date];
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier: NSCalendarIdentifierGregorian];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:now];
[components setHour:10];
NSDate *today10am = [calendar dateFromComponents:components];

in iOS8 Apple introduced a convenience method that saves a few lines of code:

NSDate *d = [calendar dateBySettingHour:10 minute:0 second:0 ofDate:[NSDate date] options:0];

Swift:

let calendar: NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
let now: NSDate! = NSDate()

let date10h = calendar.dateBySettingHour(10, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)!

Inspired by AASoft's answer, I went out to improve it a bit more:

1. Avoid the loop variable $i and the comparison with 0 in every loop
2. Wrap the execution into a try..finally block to always close the files in use
3. Make the solution work for an arbitrary number of lines to remove from the beginning of the file
4. Use a variable $p to reference the current directory

These changes lead to the following code:

$p = (Get-Location).Path

(Measure-Command {
    # Number of lines to skip
    $skip = 1
    $ins = New-Object System.IO.StreamReader ($p + "\test.log")
    $outs = New-Object System.IO.StreamWriter ($p + "\test-1.log")
    try {
        # Skip the first N lines, but allow for fewer than N, as well
        for( $s = 1; $s -le $skip -and !$ins.EndOfStream; $s++ ) {
            $ins.ReadLine()
        }
        while( !$ins.EndOfStream ) {
            $outs.WriteLine( $ins.ReadLine() )
        }
    }
    finally {
        $outs.Close()
        $ins.Close()
    }
}).TotalSeconds

The first change brought the processing time for my 60 MB file down from 5.3s to 4s. The rest of the changes is more cosmetic.

   var stringToSplit = "0, 10, 20, 30, 100, 200";

    // To parse your string 
    var elements = test.Split(new[]
    { ',' }, System.StringSplitOptions.RemoveEmptyEntries);

    // To Loop through
    foreach (string items in elements)
    {
       // enjoy
    }

We can get different return value from http_response_code via the two different environment:

1. Web Server Environment
2. CLI environment

At the web server environment, return previous response code if you provided a response code or when you do not provide any response code then it will be print the current value. Default value is 200 (OK).

At CLI Environment, true will be return if you provided a response code and false if you do not provide any response_code.

Example of Web Server Environment of Response_code's return value:

var_dump(http_respone_code(500)); // int(200)
var_dump(http_response_code()); // int(500)

Example of CLI Environment of Response_code's return value:

var_dump(http_response_code()); // bool(false)
var_dump(http_response_code(501)); // bool(true)
var_dump(http_response_code()); // int(501)

Yes, here you can use LIMIT.

You can try it by the below query:

SELECT * FROM employee_list SORT BY salary DESC LIMIT 2

Here's a function to pretty up your json: pretty_json

It is very bad practice to send all email addresses to all recipients; you should use Bcc (blind carbon copies).

    $from = "[email protected]";
    $recipList = "mailaddress1,mailaddress2,etc";
    $headers = "MIME-Version: 1.0\nContent-type: text/html; charset=utf-8\nFrom: {$from}\nBcc: {$recipList}\nDate: ".date(DATE_RFC2822);
    mail(null,$subject,$message,$headers); //send the eail

There's a very nice discussion of this specific problem over at MIT. On page 5, they make the point that, if you assume that an addition takes one computational unit, the time required to compute Fib(N) is very closely related to the result of Fib(N).

As a result, you can skip directly to the very close approximation of the Fibonacci series:

Fib(N) = (1/sqrt(5)) * 1.618^(N+1) (approximately)

and say, therefore, that the worst case performance of the naive algorithm is

O((1/sqrt(5)) * 1.618^(N+1)) = O(1.618^(N+1))

PS: There is a discussion of the closed form expression of the Nth Fibonacci number over at Wikipedia if you'd like more information.

I found several posts telling me to run several gpg commands, but they didn't solve the problem because of two things. First, I was missing the debian-keyring package on my system and second I was using an invalid keyserver. Try different keyservers if you're getting timeouts!

Thus, the way I fixed it was:

apt-get install debian-keyring
gpg --keyserver pgp.mit.edu --recv-keys 1F41B907
gpg --armor --export 1F41B907 | apt-key add -

Then running a new "apt-get update" worked flawlessly!

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

In some contexts using a ' character beforehand will work, but if you save to CSV and load again this is impossible.

Taken from here:

You can use Notepad++ to accomplish this in three ways. Just so you know, Notepad++ is a more advanced version of Notepad, which supports syntax highlighting of different code files "out of the box" - PHP included!

Download & install it, fire it up, and load up your PHP file. You should automatically see it beautifully coloured (if not, because the file extension is something other than .php, go to Language -> PHP or Language -> P -> PHP).

If you need to change any of the colours, you can easily do so - just go to Settings -> Styler Configurator. From that menu, you can change the various highlighting and font options, to suit your needs - although the default usually suffices for most.

Then, go to Plugins -> NppExport. From there, you have three options you can consider:

Export to RTF Export to HTML Copy all formats to clipboard Start with the last one - "Copy all formats to clipboard" - which will copy the entire file with the highlighted syntax to the clipboard. Once you click it, then open Microsoft Word, and just hit paste! You should see the beautifully syntax-highlighted code. If something goes wrong, then you can try one of the other options (export to RTF/HTML), although I've never had a problem with the clipboard method.

To put it simply, if in linear regression model more test cases arrive which are far away from the threshold(say =0.5)for a prediction of y=1 and y=0. Then in that case the hypothesis will change and become worse.Therefore linear regression model is not used for classification problem.

Another Problem is that if the classification is y=0 and y=1, h(x) can be > 1 or < 0.So we use Logistic regression were 0<=h(x)<=1.

Try this, it works for me:

var storage = null;
setLocalStorage();

function setLocalStorage() {
    storage = (localStorage ? localStorage : (window.content.localStorage ? window.content.localStorage : null));

    try {
        storage.setItem('test_key', 'test_value');//verify if posible saving in the current storage
    }
    catch (e) {
        if (e.name == "NS_ERROR_FILE_CORRUPTED") {
            storage = sessionStorage ? sessionStorage : null;//set the new storage if fails
        }
    }
}

Check out Pathname and in particular Pathname#exist?.

File and its FileTest module are perhaps simpler/more direct, but I find Pathname a nicer interface in general.

You can also use Yapdi:

Basic usage:

import yapdi

daemon = yapdi.Daemon()
retcode = daemon.daemonize()

# This would run in daemon mode; output is not visible
if retcode == yapdi.OPERATION_SUCCESSFUL:
print('Hello Daemon')

Kotlin

val number = 088899998888

val phone = number.phoneFormatter()

fun String.phoneFormatter(): String { return this.replace("\\B(?=(\\d{4})+(?!\\d))".toRegex(), "-") }

The result will be 0888-9999-8888

Another idea is to use clipToOutline property of an ImageView.

Here is an example layout:

<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Simple view to draw borders for an image,
         borders will be rounded because of the oval-shaped background. -->
    <View
        android:id="@+id/v_border"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:background="@drawable/shape_border"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <!-- Image itself: fits the border view, 
         a margin serves as a border width;
         the key point here - is a background shape which will clip the view to its forms. -->
    <ImageView
        android:id="@+id/iv_image"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_margin="4dp"
        android:background="@drawable/shape_oval"
        android:src="@mipmap/ic_launcher"
        app:layout_constraintBottom_toBottomOf="@+id/v_border"
        app:layout_constraintEnd_toEndOf="@+id/v_border"
        app:layout_constraintStart_toStartOf="@+id/v_border"
        app:layout_constraintTop_toTopOf="@+id/v_border" />

</androidx.constraintlayout.widget.ConstraintLayout>

And here are our shape_border drawable:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <solid android:color="#FF00FF" />
</shape>

And shape_oval drawable:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" />

The only thing you should do in the code - is to enable clipToOutline property:

binding.ivImage.clipToOutline = true

And of course you can avoid even this line of the code with some BindingAdapter.

The double underscore. It mangles the name in such a way that it can't be accessed simply through __fieldName from outside the class, which is what you want to begin with if they're to be private. (Though it's still not very hard to access the field.)

class Foo:
    def __init__(self):
        self.__privateField = 4;
        print self.__privateField # yields 4 no problem

foo = Foo()
foo.__privateField
# AttributeError: Foo instance has no attribute '__privateField'

It will be accessible through _Foo__privateField instead. But it screams "I'M PRIVATE DON'T TOUCH ME", which is better than nothing.

Apparently the question poorly describes the OP's problem, but this question is the top search result for dragging to reorder table rows, so that is what I will answer. I wasn't interested in bringing in jQuery UI for something so simple, so here is a jQuery only solution:

$(".grab").mousedown(function(e) {
  var tr = $(e.target).closest("TR"),
    si = tr.index(),
    sy = e.pageY,
    b = $(document.body),
    drag;
  if (si == 0) return;
  b.addClass("grabCursor").css("userSelect", "none");
  tr.addClass("grabbed");

  function move(e) {
    if (!drag && Math.abs(e.pageY - sy) < 10) return;
    drag = true;
    tr.siblings().each(function() {
      var s = $(this),
        i = s.index(),
        y = s.offset().top;
      if (i > 0 && e.pageY >= y && e.pageY < y + s.outerHeight()) {
        if (i < tr.index())
          tr.insertAfter(s);
        else
          tr.insertBefore(s);
        return false;
      }
    });
  }

  function up(e) {
    if (drag && si != tr.index()) {
      drag = false;
      alert("moved!");
    }
    $(document).unbind("mousemove", move).unbind("mouseup", up);
    b.removeClass("grabCursor").css("userSelect", "none");
    tr.removeClass("grabbed");
  }
  $(document).mousemove(move).mouseup(up);
});

.grab {
  cursor: grab;
}

.grabbed {
  box-shadow: 0 0 13px #000;
}

.grabCursor,
.grabCursor * {
  cursor: grabbing !important;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
  <tr>
    <th></th>
    <th>Table Header</th>
  </tr>
  <tr>
    <td class="grab">&#9776;</td>
    <td>Table Cell 1</td>
  </tr>
  <tr>
    <td class="grab">&#9776;</td>
    <td>Table Cell 2</td>
  </tr>
  <tr>
    <td class="grab">&#9776;</td>
    <td>Table Cell 3</td>
  </tr>
</table>

Note si == 0 and i > 0 ignores the first row, which for me contains TH tags. Replace the alert with your "drag finished" logic.

Unlike it's most popular commercial competitor, numpy pretty much from the outset is about "arbitrary-dimensional" arrays, that's why the core class is called ndarray. You can check the dimensionality of a numpy array using the .ndim property. The .shape property is a tuple of length .ndim containing the length of each dimensions. Currently, numpy can handle up to 32 dimensions:

a = np.ones(32*(1,))
a
# array([[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[ 1.]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]])
a.shape
# (1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)
a.ndim
# 32

If a numpy array happens to be 2d like your second example, then it's appropriate to think about it in terms of rows and columns. But a 1d array in numpy is truly 1d, no rows or columns.

If you want something like a row or column vector you can achieve this by creating a 2d array with one of its dimensions equal to 1.

a = np.array([[1,2,3]]) # a 'row vector'
b = np.array([[1],[2],[3]]) # a 'column vector'
# or if you don't want to type so many brackets:
b = np.array([[1,2,3]]).T

The accepted answer didn't work with my form, even when I stripped it down to the bare minimum and copied & pasted the code. If anyone else is having this problem, please give my solution a try. Basically, you set Top and Left to 50% as the OP did, but offset the form's container with negative margins on the top and left equal to 50% of the div's height and width, respectively. This moves the center point of the Top and Left coordinates to the center of the form. I will stress that the height and width of the form must be specified (not relative). In this example, a 300x300px form div with margins of -150px on the top and left is perfectly centered no matter the window size:

HTML

<body>
    <div class="login_div">
        <form class="login_form" action="#">
        </form>
    </div>
</body>

CSS

.login_div {
    position: absolute;

    width: 300px;
    height: 300px;

    /* Center form on page horizontally & vertically */
    top: 50%;
    left: 50%;
    margin-top: -150px;
    margin-left: -150px;
}

.login_form {
    width: 300px;
    height: 300px;

    background: gray;
    border-radius: 10px;

    margin: 0;
    padding: 0;
}

JSFiddle

Now, for those wondering why I used a container for the form, it's because I like to have the option of placing other elements in the form's vicinity and having them centered as well. The form container is completely unnecessary in this example, but would definitely be useful in other cases. Hope this helps!

The problem is that in IE (which is what I presume you're testing in), the <iframe> element has a document property that refers to the document containing the iframe, and this is getting used before the contentDocument or contentWindow.document properties. What you need is:

function GetDoc(x) {
    return x.contentDocument || x.contentWindow.document;
}

Also, document.all is not available in all browsers and is non-standard. Use document.getElementById() instead.

It would be nice to be able to specify a port other than 3000, either as a command line parameter or an environment variable.

Right now, the process is pretty involved:

1. Run npm run eject
2. Wait for that to finish
3. Edit scripts/start.js and find/replace 3000 with whatever port you want to use
4. Edit config/webpack.config.dev.js and do the same

This is a one line to solve the complete original question:

params.select { |k,_| k[/choice/]}.values.join('\t')

But most the solutions above are solving a case where you need to know the keys ahead of time, using slice or simple regexp.

Here is another approach that works for simple and more complex use cases, that is swappable at runtime

data = {}
matcher = ->(key,value) { COMPLEX LOGIC HERE }
data.select(&matcher)

Now not only this allows for more complex logic on matching the keys or the values, but it is also easier to test, and you can swap the matching logic at runtime.

Ex to solve the original issue:

def some_method(hash, matcher) 
  hash.select(&matcher).values.join('\t')
end

params = { :irrelevant => "A String",
           :choice1 => "Oh look, another one",
           :choice2 => "Even more strings",
           :choice3 => "But wait",
           :irrelevant2 => "The last string" }

some_method(params, ->(k,_) { k[/choice/]}) # => "Oh look, another one\\tEven more strings\\tBut wait"
some_method(params, ->(_,v) { v[/string/]}) # => "Even more strings\\tThe last string"

Try passing multiple values via url:

/ReportServer?%2fService+Specific+Reports%2fFilings%2fDrillDown%2f&StartDate=01/01/2010&EndDate=01/05/2010&statuses=1&statuses=2&rs%3AFormat=PDF

This should work.

Convert each character to its ASCII code, subtract the ASCII code for "a" and add 1. I'm deliberately leaving the code as an exercise.

This sounds like homework. If so, please tag it as such.

Also, this won't deal with upper case letters, since you didn't state any requirement to handle them, but if you need to then just lowercase the string before you start.

Oh, and this will only deal with the latin "a" through "z" characters without any accents, etc.

As you run the container, a directory on your host is created and mounted into the container. You can find out what directory this is with

$ docker inspect --format "{{ .Volumes }}" <ID>
map[/export:/var/lib/docker/vfs/dir/<VOLUME ID...>]

If you want to mount a directory from your host inside your container, you have to use the -v parameter and specify the directory. In your case this would be:

docker run -v /export:/export data

SO you would use the hosts folder inside your container.

Declare them before the while loop.

$hn = "";
$pid = "";
$datereg = "";
$prefix = "";
$fname = "";
$lname = "";
$age = "";
$sex = "";

You are getting the notice because the variables are declared and assigned inside the loop.

Not naturally, no... However, a googling of the thing gave this: http://phpjs.org/functions/isset:454

This works for me:

1. Create a new shell file job. So let's say: touch job.sh and add command to run python script (you can even add command line arguments to that python, I usually predefine my command line arguments).

   chmod +x job.sh

2. Inside job.sh add the following py files, let's say:

   python_file.py argument1 argument2 argument3 >> testpy-output.txt && echo "Done with python_file.py"

   python_file1.py argument1 argument2 argument3 >> testpy-output.txt && echo "Done with python_file1.py"

Done with python_file.py

Done with python_file1.py

I use this usually when I have to run multiple python files with different arguments, pre defined.

Note: Just a quick heads up on what's going on here:

python_file.py argument1 argument2 argument3 >> testpy-output.txt && echo "completed with python_file.py" . 

• Here shell script will run the file python_file.py and add multiple command-line arguments at run time to the python file.
• This does not necessarily means, you have to pass command line arguments as well.
• You can just use it like: python python_file.py, plain and simple. Next up, the >> will print and store the output of this .py file in the testpy-output.txt file.
• && is a logical operator that will run only after the above is executed successfully and as an optional echo "completed with python_file.py" will be echoed on to your cli/terminal at run time.

I can reproduce steps without any problem.

Please try:

(1) remove this line from your index.html

<script src="node_modules/es6-shim/es6-shim.js"></script>

(2) modify file: app.components.ts, delete "," at the end of line in template field

@Component({
    selector: 'my-app',
    template: '<h1>My First Angular 2 App</h1>'
})

Here is my environment:

$ node -v

$ npm -v

A more explicit option is to project collection to an IEnumerable of KeyValuePair and then convert it to a Dictionary.

Dictionary<int, string> dictionary = objects
    .Select(x=> new KeyValuePair<int, string>(x.Id, x.Name))
    .ToDictionary(x=>x.Key, x=>x.Value);

1 - disable fork option in /etc/mongodb.conf if enabled

2 - Repair your database

mongod --repair --dbpath DBPATH

3 - kill current mongod process

Find mongo processes

ps -ef | grep mongo

you'll get mongod PID

mongodb   PID     1  0 06:26 ?        00:00:00 /usr/bin/mongod --config /etc/mongodb.conf

Stop current mongod process

kill -9 PID

4 - start mongoDB service

service mongodb start

There are two ways to specify label for element:

1. Setting label's "for" attribute to element's id
2. Placing element inside label

So, the proper way to find element's label is

   var $element = $( ... )

   var $label = $("label[for='"+$element.attr('id')+"']")
   if ($label.length == 0) {
     $label = $element.closest('label')
   }

   if ($label.length == 0) {
     // label wasn't found
   } else {
     // label was found
   }

How to check if a string is a valid date using Moment, when the date and date format are different

Sorry, but did any of the given solutions on this thread actually answer the question that was asked?

I have a String date and a date format which is different. Ex.: date: 2016-10-19 dateFormat: "DD-MM-YYYY". I need to check if this date is a valid date.

The following works for me...

const date = '2016-10-19';
const dateFormat = 'DD-MM-YYYY';
const toDateFormat = moment(new Date(date)).format(dateFormat);
moment(toDateFormat, dateFormat, true).isValid();

// Note: `new Date()` circumvents the warning that
// Moment throws (https://momentjs.com/guides/#/warnings/js-date/),
// but may not be optimal.

But honestly, don't understand why moment.isDate()(as documented) only accepts an object. Should also support a string in my opinion.

Up front .. I am a Hudson committer and author of the Hudson book, but I was not involved in the whole split of the projects.

In any case here is my advice:

Check out both and see what fits your needs better.

Hudson is going to complete the migration to be a top level Eclipse projects later this year and has gotten a whole bunch of full time developers, QA and others working on the project. It is still going strong and has a lot of users and with being the default CI server at Eclipse it will continue to serve the needs of many Java developers. Looking at the roadmap and plans for the future you can see that after the Maven 3 integration accomplished with the 2.1.0 release a whole bunch of other interesting feature are ahead.

http://www.eclipse.org/hudson

Jenkins on the other side has won over many original Hudson users and has a large user community across multiple technologies and also has a whole bunch of developers working on it.

At this stage both CI servers are great tools to use and depending on your needs in terms of technology to integrate with one or the other might be better. Both products are available as open source and you can get commercial support from various companies for both.

In any case .. if you are not using a CI server yet.. start now with either of them and you will see huge benefits.

Update Jan 2013: After a long process of IP cleanup and further improvements Hudson 3.0 as the first Eclipse foundation approved release is now available.

varName.replace(/[\r\n]/mg, '')                                              

The problem went away when I did

sudo service apache2 restart

Here's a simpler solution that worked for me:

In XCode5, double-click on your app's target. This brings up the Info pane for the target. In the "Build Settings" section, check the "code signing" section for any old profiles and replace with the correct one. update the value of "code signing identity" and "provisioning profile"

Bootstrap offers various table styles. Have a look at Base CSS - Tables for documentation and examples.

The following style gives great looking tables:

<table class="table table-striped table-bordered table-condensed">
  ...
</table>

Also you can:

1. Set a breakpoint to pause the execution.
2. The object must be inside the execution scope
3. Move the mouse pointer over the object or variable
4. A yellow tooltip will appear
5. Move the mouse over the tooltip
6. Click over the two little arrows pointing up and down
7. A context menu will pop up
8. Select "Print Description", it will execute a [object description]
9. The description will appear in the console's output

IMHO a little bit hidden and cumbersome...

use java.util.Random to generate a random number between 0 and array length: random_number, and then use the random number to get the integer: array[random_number]

You could decorate the property you wish controlling its name with the [JsonProperty] attribute which allows you to specify a different name:

using Newtonsoft.Json;
// ...

[JsonProperty(PropertyName = "FooBar")]
public string Foo { get; set; }

In your Ruby on Rails controller you can use:

private

before_filter :safari_cookie_fix

def safari_cookie_fix
  user_agent = UserAgent.parse(request.user_agent) # Uses useragent gem!
  if user_agent.browser == 'Safari' # we apply the fix..
    return if session[:safari_cookie_fixed] # it is already fixed.. continue
    if params[:safari_cookie_fix].present? # we should be top window and able to set cookies.. so fix the issue :)
      session[:safari_cookie_fixed] = true
      redirect_to params[:return_to]
    else
      # Redirect the top frame to your server..
      render :text => "<script>alert('start redirect');top.window.location='?safari_cookie_fix=true&return_to=#{set_your_return_url}';</script>"
    end
  end
end

Horizontal scrollbars in a HTML Select are not natively supported. However, here's a way to create the appearance of a horizontal scrollbar:

1. First create a css class

<style type="text/css">
 .scrollable{
   overflow: auto;
   width: 70px; /* adjust this width depending to amount of text to display */
   height: 80px; /* adjust height depending on number of options to display */
   border: 1px silver solid;
 }
 .scrollable select{
   border: none;
 }
</style>

2. Wrap the SELECT inside a DIV - also, explicitly set the size to the number of options.

<div class="scrollable">
<select size="6" multiple="multiple">
    <option value="1" selected>option 1 The Long Option</option>
    <option value="2">option 2</option>
    <option value="3">option 3</option>
    <option value="4">option 4</option>
    <option value="5">option 5 Another Longer than the Long Option ;)</option>
    <option value="6">option 6</option>
</select>
</div>
