I combined these two answers: https://stackoverflow.com/a/9524878/86967 and https://stackoverflow.com/a/7390874/86967 and did some escaping so that this could be used from inside a makefile.

.PHONY: no_targets__ list
no_targets__:
list:
    sh -c "$(MAKE) -p no_targets__ | awk -F':' '/^[a-zA-Z0-9][^\$$#\/\\t=]*:([^=]|$$)/ {split(\$$1,A,/ /);for(i in A)print A[i]}' | grep -v '__\$$' | sort"

.

$ make -s list
build
clean
default
distclean
doc
fresh
install
list
makefile ## this is kind of extraneous, but whatever...
run

To change dir

foo: 
    $(MAKE) -C mydir

multi:
    $(MAKE) -C / -C my-custom-dir   ## Equivalent to /my-custom-dir

When you run make, add VERBOSE=1 to see the full command output. For example:

cmake .
make VERBOSE=1

Or you can add -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON to the cmake command for permanent verbose command output from the generated Makefiles.

cmake -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON .
make

To reduce some possibly less-interesting output you might like to use the following options. The option CMAKE_RULE_MESSAGES=OFF removes lines like [ 33%] Building C object..., while --no-print-directory tells make to not print out the current directory filtering out lines like make[1]: Entering directory and make[1]: Leaving directory.

cmake -DCMAKE_RULE_MESSAGES:BOOL=OFF -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON .
make --no-print-directory

I simply ran the command below:

export LD_LIBRARY_PATH=/usr/lib/

Now it is working fine.

The problem is that echo works only under an execution block. i.e. anything after "xx:"

So anything above the first execution block is just initialization so no execution command can used.

So create a execution blocl

If you're using Windows 10, it is built into the Linux subsystem feature. Just launch a Bash prompt (press the Windows key, then type bash and choose "Bash on Ubuntu on Windows"), cd to the directory you want to make and type make.

FWIW, the Windows drives are found in /mnt, e.g. C:\ drive is /mnt/c in Bash.

If Bash isn't available from your start menu, here are instructions for turning on that Windows feature (64-bit Windows only):

https://docs.microsoft.com/en-us/windows/wsl/install-win10

A relatively easy way of doing this is to write the entire sequence as a shell script.

out.tar:
   set -e ;\
   TMP=$$(mktemp -d) ;\
   echo hi $$TMP/hi.txt ;\
   tar -C $$TMP cf $@ . ;\
   rm -rf $$TMP ;\

I have consolidated some related tips here: https://stackoverflow.com/a/29085684/86967

When you use VARIABLE = value, if value is actually a reference to another variable, then the value is only determined when VARIABLE is used. This is best illustrated with an example:

VAL = foo
VARIABLE = $(VAL)
VAL = bar

# VARIABLE and VAL will both evaluate to "bar"

When you use VARIABLE := value, you get the value of value as it is now. For example:

VAL = foo
VARIABLE := $(VAL)
VAL = bar

# VAL will evaluate to "bar", but VARIABLE will evaluate to "foo"

Using VARIABLE ?= val means that you only set the value of VARIABLE if VARIABLE is not set already. If it's not set already, the setting of the value is deferred until VARIABLE is used (as in example 1).

VARIABLE += value just appends value to VARIABLE. The actual value of value is determined as it was when it was initially set, using either = or :=.

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

In general, you either have to specify $(OBJDIR) on the left hand side of all the rules that place files in $(OBJDIR), or you can run make from $(OBJDIR). VPATH is for sources, not for objects.

Take a look at these two links for more explanation, and a "clever" workaround.

• http://mad-scientist.net/make/vpath.html
• http://mad-scientist.net/make/multi-arch.html

Example for your reference, as below:

The folder structure might be as:

Where there are two Makefiles, each as below;

sample/Makefile
test/Makefile

Now, let us see the content of the Makefiles.

sample/Makefile

export ROOT_DIR=${PWD}

all:
    echo ${ROOT_DIR}
    $(MAKE) -C test

test/Makefile

all:
    echo ${ROOT_DIR}
    echo "make test ends here !"

Now, execute the sample/Makefile, as;

cd sample
make

OUTPUT:

echo /home/symphony/sample
/home/symphony/sample
make -C test
make[1]: Entering directory `/home/symphony/sample/test'
echo /home/symphony/sample
/home/symphony/sample
echo "make test ends here !"
make test ends here !
make[1]: Leaving directory `/home/symphony/sample/test'

Explanation, would be that the parent/home directory can be stored in the environment-flag, and can be exported, so that it can be used in all the sub-directory makefiles.

As an alternative, if you just want to install make, you can use the chocolatey package manager to install gnu make by using

choco install make -y

This deals with any path issues that you might have.

http://www.gnu.org/software/make/manual/make.html#Recursion

 subsystem:
         cd subdir && $(MAKE)

or, equivalently, this :

 subsystem:
         $(MAKE) -C subdir

You can use Target-specific Variable Values. Example:

CXXFLAGS = -g3 -gdwarf2
CCFLAGS = -g3 -gdwarf2

all: executable

debug: CXXFLAGS += -DDEBUG -g
debug: CCFLAGS += -DDEBUG -g
debug: executable

executable: CommandParser.tab.o CommandParser.yy.o Command.o
    $(CXX) -o output CommandParser.yy.o CommandParser.tab.o Command.o -lfl

CommandParser.yy.o: CommandParser.l 
    flex -o CommandParser.yy.c CommandParser.l
    $(CC) -c CommandParser.yy.c

Remember to use $(CXX) or $(CC) in all your compile commands.

Then, 'make debug' will have extra flags like -DDEBUG and -g where as 'make' will not.

On a side note, you can make your Makefile a lot more concise like other posts had suggested.

If your items are wider than the ListBox, the other answers here won't help: the items in the ItemTemplate remain wider than the ListBox.

The fix that worked for me was to disable the horizontal scrollbar, which, apparently, also tells the container of all those items to remain only as wide as the list box.

Hence the combined fix to get ListBox items that are as wide as the list box, whether they are smaller and need stretching, or wider and need wrapping, is as follows:

<ListBox HorizontalContentAlignment="Stretch" 
         ScrollViewer.HorizontalScrollBarVisibility="Disabled">

(credits for the scroll bar idea)

I was curious to see the results of the methods provided in the question as well as the accepted answer, so I put it to the test.

Here's the code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Threading.Tasks;

namespace AsyncTest
{
    class Program
    {
        class Worker
        {
            public int Id;
            public int SleepTimeout;

            public async Task DoWork(DateTime testStart)
            {
                var workerStart = DateTime.Now;
                Console.WriteLine("Worker {0} started on thread {1}, beginning {2} seconds after test start.",
                    Id, Thread.CurrentThread.ManagedThreadId, (workerStart-testStart).TotalSeconds.ToString("F2"));
                await Task.Run(() => Thread.Sleep(SleepTimeout));
                var workerEnd = DateTime.Now;
                Console.WriteLine("Worker {0} stopped; the worker took {1} seconds, and it finished {2} seconds after the test start.",
                   Id, (workerEnd-workerStart).TotalSeconds.ToString("F2"), (workerEnd-testStart).TotalSeconds.ToString("F2"));
            }
        }

        static void Main(string[] args)
        {
            var workers = new List<Worker>
            {
                new Worker { Id = 1, SleepTimeout = 1000 },
                new Worker { Id = 2, SleepTimeout = 2000 },
                new Worker { Id = 3, SleepTimeout = 3000 },
                new Worker { Id = 4, SleepTimeout = 4000 },
                new Worker { Id = 5, SleepTimeout = 5000 },
            };

            var startTime = DateTime.Now;
            Console.WriteLine("Starting test: Parallel.ForEach...");
            PerformTest_ParallelForEach(workers, startTime);
            var endTime = DateTime.Now;
            Console.WriteLine("Test finished after {0} seconds.\n",
                (endTime - startTime).TotalSeconds.ToString("F2"));

            startTime = DateTime.Now;
            Console.WriteLine("Starting test: Task.WaitAll...");
            PerformTest_TaskWaitAll(workers, startTime);
            endTime = DateTime.Now;
            Console.WriteLine("Test finished after {0} seconds.\n",
                (endTime - startTime).TotalSeconds.ToString("F2"));

                (endTime - startTime).TotalSeconds.ToString("F2"));

            Console.ReadKey();
        }

        static void PerformTest_ParallelForEach(List<Worker> workers, DateTime testStart)
        {
            Parallel.ForEach(workers, worker => worker.DoWork(testStart).Wait());

        }

        {
            return Task.WhenAll(workers.Select(worker => worker.DoWork(testStart)));
        }
    }

SUBSTRING ( MyColumn, 1 , 1 ) for the first character and SUBSTRING ( MyColumn, 1 , 2 ) for the first two.

That's because the browser doesn't transmit that part to the server, sorry.

I wrote this awhile back. It assumes the delimiter is a comma and that the individual values aren't bigger than 127 characters. It could be modified pretty easily.

It has the benefit of not being limited to 4,000 characters.

Good luck!

You can simply use .toString().

var result = require('child_process').execSync('rsync -avAXz --info=progress2 "/src" "/dest"').toString();
console.log(result);

This has been tested on Node v8.5.0, I'm not sure about previous versions. According to @etov, it doesn't work on v6.3.1 - I'm not sure about in-between.

Edit: Looking back on this, I've realised that it doesn't actually answer the specific question because it doesn't show the output to you 'live' — only once the command has finished running.

However, I'm leaving this answer here because I know quite a few people come across this question just looking for how to print the result of the command after execution.

If you want to input more data into the form, you simply access the submitted data through $_POST.

If you have

<input type="text" name="firstname" />

you access it with

$firstname = $_POST["firstname"];

You could then update your query line to read

mysql_query("INSERT INTO dbProfiles (photo,firstname)
             VALUES('{$filename}','{$firstname}')");

Note: Always filter and sanitize your data.

I think it's because of right of access, you just have to write

sudo docker-compose-deps.yml up

Multiple things can cause this, I didn't bother to check your entire repository, so I'm going out on a limb here.

First off, you could be missing an annotation (@Service or @Component) from the implementation of com.example.my.services.user.UserService, if you're using annotations for configuration. If you're using (only) xml, you're probably missing the <bean> -definition for the UserService-implementation.

If you're using annotations and the implementation is annotated correctly, check that the package where the implementation is located in is scanned (check your <context:component-scan base-package= -value).

You simply need to remove v-bind (:) from selected and required attributes. Like this :-

<template>_x000D_
    <select class="form-control" v-model="selected" required @change="changeLocation">_x000D_
        <option selected>Choose Province</option>_x000D_
        <option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>_x000D_
    </select>_x000D_
</template>

You are not binding anything to the vue instance through these attributes thats why it is giving error.

The right way to do that is:

for(std::vector<T>::iterator it = v.begin(); it != v.end(); ++it) {
    it->doSomething();
 }

Where T is the type of the class inside the vector. For example if the class was CActivity, just write CActivity instead of T.

This type of method will work on every STL (Not only vectors, which is a bit better).

If you still want to use indexes, the way is:

for(std::vector<T>::size_type i = 0; i != v.size(); i++) {
    v[i].doSomething();
}

Apple has changed the interface.

Use Range("A1").Text instead of .Value

post comment edit:
Why?
Because the .Text property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92 then <- Text will return exactly what it in the cell including any formatting.
The .Value and .Value2 properties return what's stored in the cell under the hood excluding formatting. Specially .Value2 for date types, it will return the decimal representation.

If you want to dig deeper into the meaning and performance, I just found this article which seems like a good guide

another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage

now,
paste this code in a module

Sub main()

    Dim ws As Worksheet, i&, j&
    Set ws = Sheets(1)
    For i = 3 To 7
        For j = 1 To 4
            Debug.Print _
                    "row " & i & vbTab & vbTab & _
                    Cells(i, j).Text & vbTab & _
                    Cells(i, j).Value & vbTab & _
                    Cells(i, j).Value2
        Next j
    Next i
End Sub

and Analyse the output! Its really easy and there isn't much more i can do to help :)

You didn't say what you needed this list for. If something used as a blacklist for password checks is enough cracklib might be good for you. It contains over 1.5M words.

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

You can open the file using the ios::ate flag (and ios::binary flag), so the tellg() function will give you directly the file size:

ifstream file( "example.txt", ios::binary | ios::ate);
return file.tellg();

Architecture is the resulting collection of design patterns to build a system.

I guess Design is the creativity used to put all this together?

If you are still seeking for the best solution in 2018, I found the way this works perfectly if you have at least one free pseudo element( ::after or ::before ).

You just have to add class to your row like this: <div class="row vertical-divider ">

And add this to your CSS:

.row.vertical-divider [class*='col-']:not(:last-child)::after {
  background: #e0e0e0;
  width: 1px;
  content: "";
  display:block;
  position: absolute;
  top:0;
  bottom: 0;
  right: 0;
  min-height: 70px;
}

Any row with this class will now have vertical divider between all of the columns it contains...

You can see how this works in this example.

I got this error too. Solved by installing development packages. I'm using arch and it was:

sudo pacman -S base-devel

which installed:

m4, autoconf, automake, bison, fakeroot, flex, libmpc, ppl, cloog-ppl, elfutils, gcc,
libtool, make, patch, pkg-config

but I think it actually needed make and gcc. Error output said (on my machine, among other):

"You have to install development tools first."

So it was an obvious decision and it helped.

8:1 Odds(*)

var stringNumb: String = "1357"
var someNumb = Int(stringNumb)

or

var stringNumb: String = "1357"
var someNumb:Int? = Int(stringNumb)

Int(String) returns an optional Int?, not an Int.

Safe use: do not explicitly unwrap

let unwrapped:Int = Int(stringNumb) ?? 0

or

if let stringNumb:Int = stringNumb { ... }

(*) None of the answers actually addressed why var someNumb: Int = Int(stringNumb) was not working.

This is how I would code up any truth table. For xor in particular we have:

| a | b  | xor   |             |
|---|----|-------|-------------|
| T | T  | F     |             |
| T | F  | T     | a and not b |
| F | T  | T     | not a and b |
| F | F  | F     |             |

Just look at the T values in the answer column and string together all true cases with logical or. So, this truth table may be produced in case 2 or 3. Hence,

xor = lambda a, b: (a and not b) or (not a and b)

Try this : write below code on body & feel the magic :)

body oncontextmenu="return false"

Try this:

<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">

$scope.ageFilter = function (player) {
    return (player.age > $scope.min_age && player.age < $scope.max_age);
}

Servlet-mapping has two child tags, url-pattern and servlet-name. url-pattern specifies the type of urls for which, the servlet given in servlet-name should be called. Be aware that, the container will use case-sensitive for string comparisons for servlet matching.

First specification of url-pattern a web.xml file for the server context on the servlet container at server .com matches the pattern in <url-pattern>/status/*</url-pattern> as follows:

http://server.com/server/status/synopsis               = Matches
http://server.com/server/status/complete?date=today    = Matches
http://server.com/server/status                        = Matches
http://server.com/server/server1/status                = Does not match

Second specification of url-pattern A context located at the path /examples on the Agent at example.com matches the pattern in <url-pattern>*.map</url-pattern> as follows:

 http://server.com/server/US/Oregon/Portland.map    = Matches
 http://server.com/server/US/server/Seattle.map     = Matches
 http://server.com/server/Paris.France.map          = Matches
 http://server.com/server/US/Oregon/Portland.MAP    = Does not match, the extension is uppercase
 http://example.com/examples/interface/description/mail.mapi  =Does not match, the extension is mapi rather than map`

Third specification of url-mapping,A mapping that contains the pattern <url-pattern>/</url-pattern> matches a request if no other pattern matches. This is the default mapping. The servlet mapped to this pattern is called the default servlet.

The default mapping is often directed to the first page of an application. Explicitly providing a default mapping also ensures that malformed URL requests into the application return are handled by the application rather than returning an error.

The servlet-mapping element below maps the server servlet instance to the default mapping.

<servlet-mapping>
  <servlet-name>server</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

For the context that contains this element, any request that is not handled by another mapping is forwarded to the server servlet.

And Most importantly we should Know about Rule for URL path mapping

1. The container will try to find an exact match of the path of the request to the path of the servlet. A successful match selects the servlet.
2. The container will recursively try to match the longest path-prefix. This is done by stepping down the path tree a directory at a time, using the ’/’ character as a path separator. The longest match determines the servlet selected.
3. If the last segment in the URL path contains an extension (e.g. .jsp), the servlet container will try to match a servlet that handles requests for the extension. An extension is defined as the part of the last segment after the last ’.’ character.
4. If neither of the previous three rules result in a servlet match, the container will attempt to serve content appropriate for the resource requested. If a “default” servlet is defined for the application, it will be used.

Reference URL Pattern

I would agree with Benjamin, either install MAMP or MacPorts (http://www.macports.org/). Keeping your PHP install separate is simpler and avoids messing up the core PHP install if you make any mistakes!

MacPorts is a bit better for installing other software, such as ImageMagick. See a full list of available ports at http://www.macports.org/ports.php

MAMP just really does PHP, Apache and MySQL so any future PHP modules you want will need to be manually enabled. It is incredibly easy to use though.

Don't you try it with that program? It'll goto finally block and executing the finally block, but, the exception won't be handled. But, that exception can be overruled in the finally block!

In String type we have several method valueOf

static String   valueOf(boolean b) 
static String   valueOf(char c) 
static String   valueOf(char[] data) 
static String   valueOf(char[] data, int offset, int count) 
static String   valueOf(double d) 
static String   valueOf(float f) 
static String   valueOf(int i) 
static String   valueOf(long l) 
static String   valueOf(Object obj) 

As we can see those method are capable to resolve all kind of numbers

every implementation of specific method like you have presented: So for integers we have

Integer.toString(int i)

for double

Double.toString(double d)

and so on

In my opinion this is not some historical thing, but it is more useful for a developer to use the method valueOf from the String class than from the proper type, as it leads to fewer changes for us to make.

Sample 1:

public String doStuff(int num) {

  // Do something with num...

  return String.valueOf(num);

 }

Sample2:

public String doStuff(int num) {

 // Do something with num...

 return Integer.toString(num);

 }

As we see in sample 2 we have to do two changes, in contrary to sample one.

In my conclusion, using the valueOf method from String class is more flexible and that's why it is available there.

LazyStringSplitter:

#include <string>
#include <algorithm>
#include <unordered_set>

using namespace std;

class LazyStringSplitter
{
    string::const_iterator start, finish;
    unordered_set<char> chop;

public:

    // Empty Constructor
    explicit LazyStringSplitter()
    {}

    explicit LazyStringSplitter (const string cstr, const string delims)
        : start(cstr.begin())
        , finish(cstr.end())
        , chop(delims.begin(), delims.end())
    {}

    void operator () (const string cstr, const string delims)
    {
        chop.insert(delims.begin(), delims.end());
        start = cstr.begin();
        finish = cstr.end();
    }

    bool empty() const { return (start >= finish); }

    string next()
    {
        // return empty string
        // if ran out of characters
        if (empty())
            return string("");

        auto runner = find_if(start, finish, [&](char c) {
            return chop.count(c) == 1;
        });

        // construct next string
        string ret(start, runner);
        start = runner + 1;

        // Never return empty string
        // + tail recursion makes this method efficient
        return !ret.empty() ? ret : next();
    }
};

• I call this method the LazyStringSplitter because of one reason - It does not split the string in one go.
• In essence it behaves like a python generator
• It exposes a method called next which returns the next string that is split from the original
• I made use of the unordered_set from c++11 STL, so that look up of delimiters is that much faster
• And here is how it works

TEST PROGRAM

#include <iostream>
using namespace std;

int main()
{
    LazyStringSplitter splitter;

    // split at the characters ' ', '!', '.', ','
    splitter("This, is a string. And here is another string! Let's test and see how well this does.", " !.,");

    while (!splitter.empty())
        cout << splitter.next() << endl;
    return 0;
}

OUTPUT

This
is
a
string
And
here
is
another
string
Let's
test
and
see
how
well
this
does

Next plan to improve this is to implement begin and end methods so that one can do something like:

vector<string> split_string(splitter.begin(), splitter.end());

The programmatically trigger to call the autocomplete.change event is via a namespaced trigger on the source select element.

$("#CompanyList").trigger("blur.autocomplete");

Within version 1.8 of jquery UI..

.bind( "blur.autocomplete", function( event ) {
    if ( self.options.disabled ) {
        return;
    }

    clearTimeout( self.searching );
    // clicks on the menu (or a button to trigger a search) will cause a blur event
    self.closing = setTimeout(function() {
        self.close( event );
        self._change( event );
    }, 150 );
});

You have two options here. You can either add the untracked files to your Git repository (as the warning message suggested), or you can add the files to your .gitignore file, if you want Git to ignore them.

To add the files use git add:

git add Optimization/language/languageUpdate.php
git add email_test.php

To ignore the files, add the following lines to your .gitignore:

/Optimization/language/languageUpdate.php
/email_test.php

Either option should allow the git pull to succeed afterwards.

I was able to achieve this by using the webkit-line-clamp and the following css:

  -webkit-box-orient: vertical;
  overflow: hidden;
}

For me that have Visual Studio 2015 this works:
Search this in the start menu: Developer Command Prompt for VS2015 and run the program in the search result.
You can now execute your command in it, for example: cl /?

try a this one:

...
View view = inflater.inflate(R.layout.active_slide, this);
view.setMinimumWidth(200);

This a very basic solution (maybe I'm missing the full point of the question). ActiveSheet.Name will RETURN the string of the current tab name (and will reflect any future changes by the user). I just call the active sheet, set the variable and then use it as the Worksheets' object. Here I'm retrieving data from a table to set up a report for a division. This macro will work on any sheet in my workbook that is formatted for the same filter (criteria and copytorange) - each division gets their own sheet and can alter the criteria and update using this single macro.

Dim currRPT As String
ActiveSheet.Select
currRPT = (ActiveSheet.Name)
Range("A6").Select
Selection.RemoveSubtotal
Selection.AutoFilter
Range("PipeData").AdvancedFilter Action:=xlFilterCopy, CriteriaRange:=Range _
    ("C1:D2"), CopyToRange:=Range("A6:L9"), Unique:=True
Worksheets(currRPT).AutoFilter.Sort.SortFields.Clear
Worksheets(currRPT).AutoFilter.Sort.SortFields.Add Key:= _
    Range("C7"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:= _

The directory where st.rb lives is most likely not on your load path.

Assuming that st.rb is located in a directory called lib relative to where you invoke irb, you can add that lib directory to the list of directories that ruby uses to load classes or modules with this:

$: << 'lib'

For example, in order to call the module called 'foobar' (foobar.rb) that lives in the lib directory, I would need to first add the lib directory to the list of load path. Here, I am just appending the lib directory to my load path:

irb(main):001:0> require 'foobar'
LoadError: no such file to load -- foobar
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require'
        from (irb):1
irb(main):002:0> $:

irb(main):005:0> require 'foobar'
=> true

EDIT Sorry, I completely missed the fact that you are using ruby 1.9.x. All accounts report that your current working directory has been removed from LOAD_PATH for security reasons, so you will have to do something like in irb:

$: << "."

Yahoo is very easy to use and provides customized data. Use the following page to learn more.

WARNING - there are a few tutorials out there on the web that show you how to do this, but the region where you put in the stock symbols causes an error if you use it as posted. You will get a "MISSING FORMAT VALUE". The tutorials I found omits the commentary around GOOG.

SELECT t.name 
  FROM sys.tables AS t
  INNER JOIN sys.schemas AS s
  ON t.[schema_id] = s.[schema_id]

In terms of what you are doing with jQuery, my understanding is that you can chain functions like you have and the inner ones have access to variables from the outer ones. So is your ShowDialog(x) function contains these other functions, you can re-use the x variable within them and it will be taken as a reference to the parameter from the outer function.

I agree with mausch, you should really look at using POST for these actions, which will add a <form> tag around each element, but make the chances of an automated script or tool triggering the Cancel event much less likely. The Change action can remain as is because it (presumably just opens an edit form).

On my mac, running MAMP I have a few locations that would be the likely php.ini, so I edited the memory_limit to different values in the 2 suspected files, to test which one effected the actual MAMP PHP INFO page details. By doing that I was able to determine that this was the correct php.ini: /Applications/MAMP/bin/php/php7.2.10/conf/php.ini

Another option is bokeh which just went to version 0.3.

delete from [mytab]
where [mytab].primarykeyid in
(
select top 1000 primarykeyid
from [mytab]
)

If i understand correctly, can't you simply use:

foreach($arr as $key=>$value)
{
  echo $key;
}

See PHP manual

You're missing *s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2 as an attempt to call a function named 0.207 ...

For example:

> 1 + 2*(3)
[1] 7
> 1 + 2 (3)

Error: attempt to apply non-function

Your (unreproducible) expression should read:

censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) + 
                              0.207* (log(DIAM93))^2  -
                              0.0281*(log(DIAM93))^3)

Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...

You can get columns number from ResultSetMetaData:

Statement st = conn.createStatement();
ResultSet rs = st.executeQuery(query);
ResultSetMetaData rsmd = rs.getMetaData();

int columnsNumber = rsmd.getColumnCount();

Yup, and sun.misc.BASE64Decoder is way slower: 9x slower than java.xml.bind.DatatypeConverter.parseBase64Binary() and 4x slower than org.apache.commons.codec.binary.Base64.decodeBase64(), at least for a small string on Java 6 OSX.

Below is the test program I used. With Java 1.6.0_43 on OSX:

john:password = am9objpwYXNzd29yZA==
javax.xml took 373: john:password
apache took    612: john:password
sun took       2215: john:password

Btw that's with commons-codec 1.4. With 1.7 it seems to get slower:

javax.xml took 377: john:password
apache took    1681: john:password
sun took       2197: john:password

Didn't test Java 7 or other OS.

import javax.xml.bind.DatatypeConverter;
import org.apache.commons.codec.binary.Base64;
import java.io.IOException;

public class TestBase64 {
    private static volatile String save = null;
    public static void main(String argv[]) {
        String teststr = "john:password";
        String b64 = DatatypeConverter.printBase64Binary(teststr.getBytes());
        System.out.println(teststr + " = " + b64);
        try {
            final int COUNT = 1000000;
            long start;
            start = System.currentTimeMillis();
            for (int i=0; i<COUNT; ++i) {
                save = new String(DatatypeConverter.parseBase64Binary(b64));
            }
            System.out.println("javax.xml took "+(System.currentTimeMillis()-start)+": "+save);
            start = System.currentTimeMillis();
            for (int i=0; i<COUNT; ++i) {
                save = new String(Base64.decodeBase64(b64));
            }
            System.out.println("apache took    "+(System.currentTimeMillis()-start)+": "+save);
            sun.misc.BASE64Decoder dec = new sun.misc.BASE64Decoder();
            start = System.currentTimeMillis();
            for (int i=0; i<COUNT; ++i) {
                save = new String(dec.decodeBuffer(b64));
            }
            System.out.println("sun took       "+(System.currentTimeMillis()-start)+": "+save);
        } catch (Exception e) {
            System.out.println(e);
        }
    }
}

I think we can write like this:

def read_file(path, block_size=1024): 
    with open(path, 'rb') as f: 
        while True: 
            piece = f.read(block_size) 
            if piece: 
                yield piece 
            else: 
                return

for piece in read_file(path):
    process_piece(piece)

On a LAMP environment the php errors are default directed to this below file.

/var/log/httpd/error_log

All access logs come under:

/var/log/httpd/access_log

for group headers/footers:

=iif(RunningValue(*group on field*,CountDistinct,"*parent group name*") Mod 2,"White","AliceBlue")

You can also use this to “reset” the row color count within each group. I wanted the first detail row in each sub group to start with White and this solution (when used on the detail row) allowed that to happen:

=IIF(RunningValue(Fields![Name].Value, CountDistinct, "NameOfPartnetGroup") Mod 2, "White", "Wheat")

You can use the runOnUiThread() method as follows. If you're not using a ListActivity, just adapt the code to get a reference to your ArrayAdapter.

final ArrayAdapter adapter = ((ArrayAdapter)getListAdapter());
runOnUiThread(new Runnable() {
    public void run() {
        adapter.notifyDataSetChanged();
    }
});

Try from your dedicated server to telnet to smtp.gmail.com on port 465. It might be blocked by your internet provider

Let the problem be: finding the Kth largest element in an unsorted array.

Divide the array into n/5 groups where each group consisting of 5 elements.

Now a1,a2,a3....a(n/5) represent the medians of each group.

x = Median of the elements a1,a2,.....a(n/5).

Now if k<n/2 then we can remove the largets, 2nd largest and 3rd largest element of the groups whose median is greater than the x. We can now call the function again with 7n/10 elements and finding the kth largest value.

else if k>n/2 then we can remove the smallest ,2nd smallest and 3rd smallest element of the group whose median is smaller than the x. We can now call the function of again with 7n/10 elements and finding the (k-3n/10)th largest value.

Time Complexity Analysis: T(n) time complexity to find the kth largest in an array of size n.

T(n) = T(n/5) + T(7n/10) + O(n)

if you solve this you will find out that T(n) is actually O(n)

n/5 + 7n/10 = 9n/10 < n

I know that this question is pretty old, but I stumbled upon it recently, found a solution that I liked better, and figured I'd share it.

Now that Bootstrap 5 is available, there's a new approach that works similarly to using input-groups, but looks more like an ordinary form, without any CSS tweaks:

<div class="row g-3 align-items-center">
    <div class="col-auto">
        <label>Label:</label>
    </div>
    <div class="col">
        <input class="form-control">
    </div>
    <div class="col-auto">
        <button type="button" class="btn btn-primary">Button</button>
    </div>
</div>

The col-auto class makes those columns fit themselves to their contents (the label and the button in this case), and anything with a col class should be evenly distributed to take up the remaining space.

If you do it on Windows XAMPP/WAMP it probaly won't work as in my case.

I solved the problem setting up Laravel's Homestead/Vagrant solution to create my (Ubuntu) development environment - it has built-in: Nginx, PHP 5.6, PHP 7.3, PHP 7.2, PHP 7.1, MySQL, PostgreSQL, Redis, Memcached, Node... to name just a few.

See here for info how to set up the environment - it's really worth the effort!

Laravel Homestead is an official, pre-packaged Vagrant box that provides you a wonderful development environment without requiring you to install PHP, a web server, and any other server software on your local machine. No more worrying about messing up your operating system! Vagrant boxes are completely disposable. If something goes wrong, you can destroy and re-create the box in minutes!

Then you can easily switch PHP versions or set up more virtual hosts, new databases just in seconds.

In WAMP the files are served by the Apache component (the A in WAMP).

In Apache, by default the files served are located in the subdirectory htdocs of the installation directory. But this can be changed, and is actually changed when WAMP installs Apache.

The location from where the files are served is named the DocumentRoot, and is defined using a variable in Apache configuration file. The default value is the subdirectory htdocs relative to what is named the ServerRoot directory.

By default the ServerRoot is the installation directory of Apache. However this can also be redefined into the configuration file, or using the -d option of the command httpd which is used to launch Apache. The value in the configuration file overrides the -d option.

The configuration file is by default conf/httpd.conf relative to ServerRoot. But this can be changed using the -f option of command httpd.

When WAMP installs itself, it modify the default configuration file with DocumentRoot c:/wamp/www/. The files to be served need to be located here and not in the htdocs default directory.

You may change this location set by WAMP, either by modifying DocumentRoot in the default configuration file, or by using one of the two command line options -f or -d which point explicitly or implicity to a new configuration file which may hold a different value for DocumentRoot (in that case the new file needs to contain this definition, but also the rest of the configuration found in the default configuration file).

Use the following steps to select the database:

mysql -u username -p

it will prompt for password, Please enter password. Now list all the databases

show databases;

select the database which you want to select using the command:

use databaseName;

select data from any table:

select * from tableName limit 10;

You can select your database using the command use photogallery; Thanks !

The service reference is the newer interface for adding references to all manner of WCF services (they may not be web services) whereas Web reference is specifically concerned with ASMX web references.

You can access web references via the advanced options in add service reference (if I recall correctly).

I'd use service reference because as I understand it, it's the newer mechanism of the two.

Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.

Source: MSDN: Understanding Files and Filegroups

The recommended file name extension for secondary data files is .ndf, but this is not enforced.

Definitely should use a dict using the "group" + str(i) key as described in the accepted solution but I wanted to share a solution using exec. Its a way to parse strings into commands & execute them dynamically. It would allow to create these scalar variable names as per your requirement instead of using a dict. This might help in regards what not to do, and just because you can doesn't mean you should. Its a good solution only if using scalar variables is a hard requirement:

l = locals()
for i in xrange(3):
    exec("group" + str(i) + "= self.getGroup(selected, header + i)")

Another example where this could work using a Django model example. The exec alternative solution is commented out and the better way of handling such a case using the dict attribute makes more sense:

Class A(models.Model):

    ....

    def __getitem__(self, item):  # a.__getitem__('id')
        #exec("attrb = self." + item)
        #return attrb
        return self.__dict__[item]

It might make more sense to extend from a dictionary in the first place to get setattr and getattr functions.

A situation which involves parsing, for example generating & executing python commands dynamically, exec is what you want :) More on exec here.

127 means command not found

In your case, curl command was not found. Therefore it means, curl was not found.

Close RStudio before installation.

I use the ArrayDebugView add-in for Visual Studio (http://arraydebugview.sourceforge.net/).

It seems to be a long dead project (but one I'm looking at continuing myself) but the add-in still works beautifully for me in VS2010 for both C++ and C#.

It has a few quirks (tab order, modal dialog, no close button) but the ability to plot the contents of an array in a graph more than make up for it.

Edit July 2014: I have finally built a new Visual Studio extension to replace ArrayebugView's functionality. It is available on the VIsual Studio Gallery, search for ArrayPlotter or go to http://visualstudiogallery.msdn.microsoft.com/2fde2c3c-5b83-4d2a-a71e-5fdd83ce6b96?SRC=Home

Since Symfony 3.3 you can use binding, like

services:
_defaults:
    autowire: true      
    autoconfigure: true
    bind:
        $kernelProjectDir: '%kernel.project_dir%'

After that you can use parameter $kernelProjectDir in any controller OR service. Just like

class SomeControllerOrService
{
    public function someAction(...., $kernelProjectDir)
    {
          .....

Now emojis are supported! :white_check_mark: / :heavy_check_mark: gives a good impression and is widely supported:

Function | MySQL / MariaDB | PostgreSQL | SQLite
:------------ | :-------------| :-------------| :-------------
substr | :heavy_check_mark: |  :white_check_mark: | :heavy_check_mark:

renders to (here on older chromium 65.0.3x) :

In your case it should be:

Select convert(datetime,convert(varchar(10),GRADUATION_DATE,120)) as
'GRADUATION_DATE' from mydb

It's simple.

Parent parent = new Child();

In this case the type of the object is Parent. Ant Parent has only one properties. It's name.

Child child = new Child();

And in this case the type of the object is Child. Ant Child has two properties. They're name and salary.

The fact is that there's no need to initialize non-final field immediately at the declaration. Usually this’s done at run-time because often you cannot know exactly what exactly implementation will you need. For example imagine that you have a class hierarchy with class Transport at the head. And three subclasses: Car, Helicopter and Boat. And there's another class Tour which has field Transport. That is:

class Tour {
   Transport transport;
}  

As long as an user hasn't booked a trip and hasn't chosen a particular type of transport you can't initialize this field. It's first.

Second, assume that all of these classes must have a method go() but with a different implementation. You can define a basic implementation by default in the superclass Transport and own unique implementations in each subclass. With this initialization Transport tran; tran = new Car(); you can call the method tran.go() and get result without worrying about specific implementation. It’ll call overrided method from particular subclass.

Moreover you can use instance of subclass everywhere where instance of superclass is used. For example you want provide opportunity to rent your transport. If you don't use polymorphism, you have to write a lot of methods for each case: rentCar(Car car), rentBoat(Boat boat) and so forth. At the same time polymorphism allows you to create one universal method rent(Transport transport). You can pass in it object of any subclass of Transport. In addition, if over time your logic will increase up and you'll need to create another class in the hierarchy? When using polymorphism you don't need to change anything. Just extend class Transport and pass your new class into the method:

public class Airplane extends Transport {
    //implementation
}

and rent(new Airplane()). And new Airplane().go() in second case.

Use this query and then check the results.

$query = 'show tables like "test1"';

public func jsonPrint(_ o: NSObject, spacing: String = "", after: String = "", before: String = "") {
    let newSpacing = spacing + "    "
    if o.isArray() {
        print(before + "[")
        if let a = o as? Array<NSObject> {
            for object in a {
                jsonPrint(object, spacing: newSpacing, after: object == a.last! ? "" : ",", before: newSpacing)
            }
        }
        print(spacing + "]" + after)
    } else {
        if o.isDictionary() {
            print(before + "{")
            if let a = o as? Dictionary<NSObject, NSObject> {
                for (key, val) in a {
                    jsonPrint(val, spacing: newSpacing, after: ",", before: newSpacing + key.description + " = ")
                }
            }
            print(spacing + "}" + after)
        } else {
            print(before + o.description + after)
        }
    }
}

This one is pretty close to original Objective-C print style

Graph on logins / users from MS sql-docs

I created an example spreadsheet here of how to do this with simple Excel formulae, and without use of macros (you will need to make your own adjustments for getting rid of the first row, but this should be easy once you figure out how my example spreadsheet works):

Scale can be used for both full data frame and specific columns. For specific columns, following code can be used:

trainingSet[, 3:7] = scale(trainingSet[, 3:7]) # For column 3 to 7
trainingSet[, 8] = scale(trainingSet[, 8]) # For column 8 

Full data frame

trainingSet <- scale(trainingSet)

FYI to anyone who runs into problems, there is a bug in CSV timestamp export that I just spent a few hours working around. Some fields I needed to export were of type timestamp. It appears the CSV export option even in the current version (3.0.04 as of this posting) fails to put the grouping symbols around timestamps. Very frustrating since spaces in the timestamps broke my import. The best workaround I found was to write my query with a TO_CHAR() on all my timestamps, which yields the correct output, albeit with a little more work. I hope this saves someone some time or gets Oracle on the ball with their next release.

REST may not be a standard as such, but reading up on general REST documentation and blog posts should give you some guidelines for a good way to structure API URLs. Most rest APIs tend to only have resource names and resource IDs in the path. Such as:

/departments/{dept}/employees/{id}

Some REST APIs use query strings for filtering, pagination and sorting, but Since REST isn't a strict standard I'd recommend checking some REST APIs out there such as github and stackoverflow and see what could work well for your use case.

I'd recommend putting any required parameters in the path, and any optional parameters should certainly be query string parameters. Putting optional parameters in the path will end up getting really messy when trying to write URL handlers that match different combinations.

Below are the list of parameters for bootstrap carousel. Like Interval, pause, wrap:

For more details refer this link:

Hope this will help you :)

Note: This is for further help. I mean how you can customise or change default behaviour once carousel is loaded.

Although this question is 5 years old I have come across a nice solution.

Use the 'DictionaryEntry' object to pair keys and values.

Set the 'DisplayMember' and 'ValueMember' properties to:

   Me.myComboBox.DisplayMember = "Key"
   Me.myComboBox.ValueMember = "Value"

To add items to the ComboBox:

   Me.myComboBox.Items.Add(New DictionaryEntry("Text to be displayed", 1))

To retreive items like this:

MsgBox(Me.myComboBox.SelectedItem.Key & " " & Me.myComboBox.SelectedItem.Value)

What format are you wanting the output?

If you're happy with a string then consider the following C# code:

double num = 3.12345;
num.ToString("G3");

The result will be "3.12".

This link might be of use if you're using .NET. http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx

I hope that helps....but unless you identify than language you are using and the format in which you want the output it is difficult to suggest an appropriate solution.

Like codehead said, you'd have to iterate over the array indices instead of its elements. I prefer this variant over the C-style for loop:

for my $i (0 .. $#x) {
    print "$i: $x[$i]\n";
}

According to the documentation

x += y is equivalent to x = operator.iadd(x, y). Another way to put it is to say that z = operator.iadd(x, y) is equivalent to the compound statement z = x; z += y.

So x += 3 is the same as x = x + 3.

x = 2

x += 3

print(x)

will output 5.

Notice that there's also

• &=
• //=
• <<=
• %=
• *=
• @=
• |=
• **=
• >>=
• -=
• /=
• ^=

This function is way faster than a for loop for filling an array.

The Array.Copy command is a very fast memory copy function. This function takes advantage of that by repeatedly calling the Array.Copy command and doubling the size of what we copy until the array is full.

I discuss this on my blog at https://grax32.com/2013/06/fast-array-fill-function-revisited.html (Link updated 12/16/2019). Also see Nuget package that provides this extension method. http://sites.grax32.com/ArrayExtensions/

Note that this would be easy to make into an extension method by just adding the word "this" to the method declarations i.e. public static void ArrayFill<T>(this T[] arrayToFill ...

public static void ArrayFill<T>(T[] arrayToFill, T fillValue)
{
    // if called with a single value, wrap the value in an array and call the main function
    ArrayFill(arrayToFill, new T[] { fillValue });
}

public static void ArrayFill<T>(T[] arrayToFill, T[] fillValue)
{
    if (fillValue.Length >= arrayToFill.Length)
    {
        throw new ArgumentException("fillValue array length must be smaller than length of arrayToFill");
    }

    // set the initial array value
    Array.Copy(fillValue, arrayToFill, fillValue.Length);

    int arrayToFillHalfLength = arrayToFill.Length / 2;

    for (int i = fillValue.Length; i < arrayToFill.Length; i *= 2)
    {
        int copyLength = i;
        if (i > arrayToFillHalfLength)
        {
            copyLength = arrayToFill.Length - i;
        }

        Array.Copy(arrayToFill, 0, arrayToFill, i, copyLength);
    }
}

if(demon!=0&& num/demon>10)

Since the short-circuit form of AND(&&) is used, there is no risk of causing a run-time exception when demon is zero.

Ref. Java 2 Fifth Edition by Herbert Schildt

As explained here, you can use:

function replaceall(str,replace,with_this)
{
    var str_hasil ="";
    var temp;

    for(var i=0;i<str.length;i++) // not need to be equal. it causes the last change: undefined..
    {
        if (str[i] == replace)
        {
            temp = with_this;
        }
        else
        {
                temp = str[i];
        }

        str_hasil += temp;
    }

    return str_hasil;
}

... which you can then call using:

var str = "50.000.000";
alert(replaceall(str,'.',''));

The function will alert "50000000"

What I did is first check what are the running processes by

SELECT * FROM pg_stat_activity WHERE state = 'active';

Find the process you want to kill, then type:

SELECT pg_cancel_backend(<pid of the process>)

This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.

If the process cannot be killed, try:

SELECT pg_terminate_backend(<pid of the process>)

Just throwing this out there: if you happen to need to match against more than one string, for example abc and def, you can combine two comprehensions as follows:

matchers = ['abc','def']
matching = [s for s in my_list if any(xs in s for xs in matchers)]

Output:

['abc-123', 'def-456', 'abc-456']

 
            string[] result = new string[table.Columns.Count];
            DataRow dr = table.Rows[0];
            for (int i = 0; i < dr.ItemArray.Length; i++)
            {
                result[i] = dr[i].ToString();
            }
            foreach (string str in result)
                Console.WriteLine(str);

The simpliest way to understand it is that DateTime is a struct. When you initialize a struct it's initialize to it's minimum value : DateTime.Min

Therefore there is no difference between default(DateTime) and new DateTime() and DateTime.Min

As you are using Excel you do not need VBA to achieve this, you can simply use the built in "Clean()" function, this removes carriage returns, line feeds etc e.g:

=Clean(MyString)

There is a segmentation fault problem which was introduced in 0.1.39. You may check my repository that fixed this one in meanwhile: https://github.com/vdudouyt/mhddfs-nosegfault

The notation that is used in

a[::-1]

means that for a given string/list/tuple, you can slice the said object using the format

<object_name>[<start_index>, <stop_index>, <step>]

This means that the object is going to slice every "step" index from the given start index, till the stop index (excluding the stop index) and return it to you.

In case the start index or stop index is missing, it takes up the default value as the start index and stop index of the given string/list/tuple. If the step is left blank, then it takes the default value of 1 i.e it goes through each index.

So,

a = '1234'
print a[::2]

would print

13

Now the indexing here and also the step count, support negative numbers. So, if you give a -1 index, it translates to len(a)-1 index. And if you give -x as the step count, then it would step every x'th value from the start index, till the stop index in the reverse direction. For example

a = '1234'
print a[3:0:-1]

This would return

432

Note, that it doesn't return 4321 because, the stop index is not included.

Now in your case,

str(int(a[::-1]))

would just reverse a given integer, that is stored in a string, and then convert it back to a string

i.e "1234" -> "4321" -> 4321 -> "4321"

If what you are trying to do is just reverse the given string, then simply a[::-1] would work .

Welcome to bash. It's an old, dark and mysterious thing, capable of great magic. :-)

The option you're asking about is for the find command though, not for bash. From your command line, you can man find to see the options.

The one you're looking for is -o for "or":

  list="$(find /home/user/Desktop -name '*.bmp' -o -name '*.txt')"

That said ... Don't do this. Storage like this may work for simple filenames, but as soon as you have to deal with special characters, like spaces and newlines, all bets are off. See ParsingLs for details.

$ touch 'one.txt' 'two three.txt' 'foo.bmp'
$ list="$(find . -name \*.txt -o -name \*.bmp -type f)"
$ for file in $list; do if [ ! -f "$file" ]; then echo "MISSING: $file"; fi; done
MISSING: ./two
MISSING: three.txt

Pathname expansion (globbing) provides a much better/safer way to keep track of files. Then you can also use bash arrays:

$ a=( *.txt *.bmp )
$ declare -p a
declare -a a=([0]="one.txt" [1]="two three.txt" [2]="foo.bmp")
$ for file in "${a[@]}"; do ls -l "$file"; done
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 one.txt
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 two three.txt
-rw-r--r--  1 ghoti  staff  0 24 May 16:27 foo.bmp

The Bash FAQ has lots of other excellent tips about programming in bash.

if ($done)
{
    header("Location: /url/to/the/other/page");

To exit

let exitCode = 1;
process.exit(exitCode)

Useful exit codes

1 - Catchall for general errors
2 - Misuse of shell builtins (according to Bash documentation)
126 - Command invoked cannot execute
127 - “command not found”
128 - Invalid argument to exit

Write the below command from your repo terminal:

git remote set-url origin [email protected]:<username>/<repo>.git

Refer this link for more details about changing the url in the remote.

The following may help give you want you need:

SELECT
    index_owner, index_name, table_name, column_name, column_position
FROM DBA_IND_COLUMNS
ORDER BY
    index_owner, 
    table_name,
    index_name,
    column_position
    ;

For my use case, I wanted the column_names and order that they are in the indices (so that I could recreate them in a different database engine after migrating to AWS). The following was what I used, in case it is of use to anyone else:

SELECT
    index_name, table_name, column_name, column_position
FROM DBA_IND_COLUMNS
WHERE
    INDEX_OWNER = 'FOO'
    AND TABLE_NAME NOT LIKE '%$%'
ORDER BY
    table_name,
    index_name,
    column_position
    ;

You can also use between:

df[df.some_date.between(start_date, end_date)]

There is the index method, i = array.index(value), but I don't think you can specify a custom comparison operator. It wouldn't be hard to write your own function to do so, though:

def custom_index(array, compare_function):
    for i, v in enumerate(array):
        if compare_function(v):
            return i

Any time you do a remove() or a removeAll(), you should call

  validate();
  repaint();

after you have completed add()'ing the new components.

Calling validate() or revalidate() is mandatory when you do a remove() - see the relevant javadocs.

My own testing indicates that repaint() is also necessary. I'm not sure exactly why.

You are right, the second Dockerfile will overwrite the CMD command of the first one. Docker will always run a single command, not more. So at the end of your Dockerfile, you can specify one command to run. Not more.

But you can execute both commands in one line:

FROM centos+ssh
EXPOSE 22
EXPOSE 4149
CMD service sshd start && /opt/mq/sbin/rabbitmq-server start

What you could also do to make your Dockerfile a little bit cleaner, you could put your CMD commands to an extra file:

FROM centos+ssh
EXPOSE 22
EXPOSE 4149
CMD sh /home/centos/all_your_commands.sh

And a file like this:

service sshd start &
/opt/mq/sbin/rabbitmq-server start

You technically have two options when speaking of ISO dates.

In general, if you're filtering specifically on Date values alone OR looking to persist date in a neutral fashion. Microsoft recommends using the language neutral format of ymd or y-m-d. Which are both valid ISO formats.

Note that the form '2007-02-12' is considered language-neutral only for the data types DATE, DATETIME2, and DATETIMEOFFSET.

Because of this, your safest bet is to persist/filter based on the always netural ymd format.

The code:

select convert(char(10), getdate(), 126) -- ISO YYYY-MM-DD
select convert(char(8), getdate(), 112) -- ISO YYYYMMDD (safest)

I'm new to python too. Here is something that looks like will do what you want to

axes([0.08, 0.08, 0.94-0.08, 0.94-0.08]) #[left, bottom, width, height]
axis('scaled')`

I believe this decides the size of the canvas.

You can try this way -

ObjectAnimator.ofFloat(view, "translationX", 100f).apply {
    duration = 2000
    start()
}

Note - view is your view where you want animation.

Empty returns true if the var is not set. But isset returns true even if the var is not empty.

Use cd in a subshell; the shorthand way to use this kind of subshell is parentheses.

(cd wherever; mycommand ...)

That said, if your command has an environment that it requires, it should really ensure that environment itself instead of putting the onus on anything that might want to use it (unless it's an internal command used in very specific circumstances in the context of a well defined larger system, such that any caller already needs to ensure the environment it requires). Usually this would be some kind of shell script wrapper.

Alternatively to usleep(), which is not defined in POSIX 2008 (though it was defined up to POSIX 2004, and it is evidently available on Linux and other platforms with a history of POSIX compliance), the POSIX 2008 standard defines nanosleep():

nanosleep - high resolution sleep

#include <time.h>
int nanosleep(const struct timespec *rqtp, struct timespec *rmtp);

The nanosleep() function shall cause the current thread to be suspended from execution until either the time interval specified by the rqtp argument has elapsed or a signal is delivered to the calling thread, and its action is to invoke a signal-catching function or to terminate the process. The suspension time may be longer than requested because the argument value is rounded up to an integer multiple of the sleep resolution or because of the scheduling of other activity by the system. But, except for the case of being interrupted by a signal, the suspension time shall not be less than the time specified by rqtp, as measured by the system clock CLOCK_REALTIME.

The use of the nanosleep() function has no effect on the action or blockage of any signal.

I just wanted to extend Alex's great answer to make it appropriate if you happen to want to duplicate an entire set of records:

SET @x=7;
CREATE TEMPORARY TABLE tmp SELECT * FROM invoices;
UPDATE tmp SET id=id+@x;
INSERT INTO invoices SELECT * FROM tmp;

I just had to do this and found Alex's answer a perfect jumping off point!. Of course, you have to set @x to the highest row number in the table (I'm sure you could grab that with a query). This is only useful in this very specific situation, so be careful using it when you don't wish to duplicate all rows. Adjust the math as necessary.

It seems that in lollipop and up (or maybe just a different WebView Version) that calling cprcrack's onHideCustomView() method does not work. It works if it is called from the exit fullscreen button but when you specifically call the method it will only exit fullscreen but the webView stays blank. A way around it is to simply add these lines of code to onHideCustomView():

String js = "javascript:";
js += "var _ytrp_html5_video = document.getElementsByTagName('video')[0];";
js += "_ytrp_html5_video.webkitExitFullscreen();";
webView.loadUrl(js);

This will notify the webView that fullscreen has exited.

You just need to manually set the desired permissions with chmod():

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);

    // Set perms with chmod()
    chmod($file, 0777);
    return true;
}

I found this on Microsoft Dev Center. It works correctly and ignores double-clicking in wrong places. As you see, the point is that an item gets selected before double-click event is triggered.

private void listView1_DoubleClick(object sender, EventArgs e)
{
    // user clicked an item of listview control
    if (listView1.SelectedItems.Count == 1)
    {
        //do what you need to do here            
    }

I'm probably a bit late to the party, but I wrote the junitcategorizer for my thesis project at TOPdesk. Earlier versions indeed used a company internal Parent POM. So your problems are caused by the Parent POM not being resolvable, since it is not available to the outside world.

You can either:

• Remove the <parent> block, but then have to configure the Surefire, Compiler and other plugins yourself
• (Only applicable to this specific case!) Change it to point to our Open Source Parent POM by setting:

<parent>
    <groupId>com.topdesk</groupId>
    <artifactId>open-source-parent</artifactId>
    <version>1.2.0</version>
</parent>

If you try appending the number like, say listName.append(4) , this will append 4 at last. But if you are trying to take <int> and then append it as, num = 4 followed by listName.append(num), this will give you an error as 'num' is of <int> type and listName is of type <list>. So do type cast int(num) before appending it.

I suggest using vlookup function to get the nearest match.

Step 1

Prepare data range and name it: 'numberRange':

Select the range. Go to menu: Data ? Named ranges... ? define the new named range.

Step 2

Use this simple formula:

=VLOOKUP(A2,numberRange,2)

This way you can ommit errors, and easily correct the result.

TL;DR:

• If your input is mostly strings that can be converted to floats, the try: except: method is the best native Python method.
• If your input is mostly strings that cannot be converted to floats, regular expressions or the partition method will be better.
• If you are 1) unsure of your input or need more speed and 2) don't mind and can install a third-party C-extension, fastnumbers works very well.

There is another method available via a third-party module called fastnumbers (disclosure, I am the author); it provides a function called isfloat. I have taken the unittest example outlined by Jacob Gabrielson in this answer, but added the fastnumbers.isfloat method. I should also note that Jacob's example did not do justice to the regex option because most of the time in that example was spent in global lookups because of the dot operator... I have modified that function to give a fairer comparison to try: except:.

def is_float_try(str):
    try:
        float(str)
        return True
    except ValueError:
        return False

import re
_float_regexp = re.compile(r"^[-+]?(?:\b[0-9]+(?:\.[0-9]*)?|\.[0-9]+\b)(?:[eE][-+]?[0-9]+\b)?$").match
def is_float_re(str):
    return True if _float_regexp(str) else False

def is_float_partition(element):
    partition=element.partition('.')
    if (partition[0].isdigit() and partition[1]=='.' and partition[2].isdigit()) or (partition[0]=='' and partition[1]=='.' and partition[2].isdigit()) or (partition[0].isdigit() and partition[1]=='.' and partition[2]==''):
        return True
    else:
        return False

As you can see, regex is actually not as bad as it originally seemed, and if you have a real need for speed, the fastnumbers method is quite good.

Starting with PowerShell 6, you get the filename without extension like so:

split-path c:\temp\myfile.txt -leafBase

A way to do is to go to terminal

$ sudo gedit /etc/hosts

    ipaddress of your pc  localhost(Edit your pc name with localhost) **

and again restart your ssh service using:

$ service ssh restart

If you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()
        @RenderSection("scripts", required: false)
    </body>
</html>

then you can have an index.cshtml content view like this

@section scripts {
     <script type="text/javascript">alert('hello');</script>
}

the required indicates whether or not the view using the layout page must have a scripts section

on your XAMPP control panel, next to apache, select the "Config" option and select the first file (httpd.conf):

there, look for the "listen" line (you may use the find tool in the notepad) and there must be a line stating "Listen 80". Note: there are other lines with "listen" on them but they should be commented (start with a #), the one you need to change is the one saying exactly "listen 80". Now change it to "Listen 1337".

Start apache now.

If the error subsists, it's because there's another port that's already in use. So, select the config option again (next to apache in your xampp control panel) and select the second option this time (httpd-ssl.conf):

there, look for the line "Listen 443" and change it to "Listen 7331".

Start apache, it should be working now.

There are a couple of ways to do your check for class equality before checking member equality, and I think both are useful in the right circumstances.

1. Use the instanceof operator.
2. Use this.getClass().equals(that.getClass()).

I use #1 in a final equals implementation, or when implementing an interface that prescribes an algorithm for equals (like the java.util collection interfaces—the right way to check with with (obj instanceof Set) or whatever interface you're implementing). It's generally a bad choice when equals can be overridden because that breaks the symmetry property.

Option #2 allows the class to be safely extended without overriding equals or breaking symmetry.

If your class is also Comparable, the equals and compareTo methods should be consistent too. Here's a template for the equals method in a Comparable class:

final class MyClass implements Comparable<MyClass>
{

  …

  @Override
  public boolean equals(Object obj)
  {
    /* If compareTo and equals aren't final, we should check with getClass instead. */
    if (!(obj instanceof MyClass)) 
      return false;
    return compareTo((MyClass) obj) == 0;
  }

}

InnerHTML clear all data like event for existing nodes

append child with firstChild adds only first child to innerHTML. For example if we have to append:

 <p>text1</p><p>text2</p>

only text1 will show up

What about this:

adds special tag to innerHTML by append child and then edit outerHTML by deleting tag we've created. Don't know how smart it is but it works for me or you might change outerHTML to innerHTML so it doesn't have to use function replace

function append(element, str)_x000D_
{_x000D_
_x000D_
  var child = document.createElement('someshittyuniquetag');_x000D_
  _x000D_
  child.innerHTML = str;_x000D_
_x000D_
  element.appendChild(child);_x000D_
_x000D_
  child.outerHTML = child.outerHTML.replace(/<\/?someshittyuniquetag>/, '');_x000D_
_x000D_
// or Even child.outerHTML = child.innerHTML_x000D_
_x000D_
_x000D_
  _x000D_
}

<div id="testit">_x000D_
This text is inside the div_x000D_
<button onclick="append(document.getElementById('testit'), '<button>dadasasdas</button>')">To div</button>_x000D_
<button onclick="append(this, 'some text')">to this</button>_x000D_
</div>

To replace commas with newline characters use this formula (assuming that the text to be altered is in cell A1):

=SUBSTITUTE(A1,",",CHAR(10))

You may have to then alter the row height to see all of the values in the cell

I've left a comment about the other part of your question

Edit: here's a screenshot of this working - I had to turn on "Wrap Text" in the "Format Cells" dialog.

The best way to do this is to set display: inline;. Note, however, that in inline display, you lose access to some layout properties, such as manual height and vertical margins, but this doesn't appear to be a problem for your page.

You can use my plugin waitForImages to handle this...

$(document).waitForImages(function() {
   // Loaded.
});

The advantage of this is you can localise it to one ancestor element and it can optionally detect images referenced in the CSS.

This is just the tip of the iceberg though, check the documentation for more functionality.

Here's a picture explaining the difference between pageY and clientY.

Same for pageX and clientX, respectively.

pageX/Y coordinates are relative to the top left corner of the whole rendered page (including parts hidden by scrolling),

while clientX/Y coordinates are relative to the top left corner of the visible part of the page, "seen" through browser window.

See Demo

You'll probably never need screenX/Y

For me this problem occurred because I had a some invalid character in my Groovy script. In our case this was an extra blank line after the closing bracket of the script.

What even is ‘children’?

The React docs say that you can use props.children on components that represent ‘generic boxes’ and that don’t know their children ahead of time. For me, that didn’t really clear things up. I’m sure for some, that definition makes perfect sense but it didn’t for me.

My simple explanation of what this.props.children does is that it is used to display whatever you include between the opening and closing tags when invoking a component.

A simple example:

Here’s an example of a stateless function that is used to create a component. Again, since this is a function, there is no this keyword so just use props.children

const Picture = (props) => {
  return (
    <div>
      <img src={props.src}/>
      {props.children}
    </div>
  )
}

This component contains an <img> that is receiving some props and then it is displaying {props.children}.

Whenever this component is invoked {props.children} will also be displayed and this is just a reference to what is between the opening and closing tags of the component.

//App.js
render () {
  return (
    <div className='container'>
      <Picture key={picture.id} src={picture.src}>
          //what is placed here is passed as props.children  
      </Picture>
    </div>
  )
}

Instead of invoking the component with a self-closing tag <Picture /> if you invoke it will full opening and closing tags <Picture> </Picture> you can then place more code between it.

This de-couples the <Picture> component from its content and makes it more reusable.

Just for anyone trying to do this automatically, you can use that extension method to ignore non existing properties on the destination type :

public static IMappingExpression<TSource, TDestination> IgnoreAllNonExisting<TSource, TDestination>(this IMappingExpression<TSource, TDestination> expression)
{
    var sourceType = typeof(TSource);
    var destinationType = typeof(TDestination);
    var existingMaps = Mapper.GetAllTypeMaps().First(x => x.SourceType.Equals(sourceType)
        && x.DestinationType.Equals(destinationType));
    foreach (var property in existingMaps.GetUnmappedPropertyNames())
    {
        expression.ForMember(property, opt => opt.Ignore());
    }
    return expression;
}

to be used as follow :

Mapper.CreateMap<SourceType, DestinationType>().IgnoreAllNonExisting();

thanks to Can Gencer for the tip :)

The best way to send data from a parent component to a child is using props.

Passing data from parent to child via props

• Declare props (array or object) in the child
• Pass it to the child via <child :name="variableOnParent">

See demo below:

Vue.component('child-comp', {
  props: ['message'], // declare the props
  template: '<p>At child-comp, using props in the template: {{ message }}</p>',
  mounted: function () {
    console.log('The props are also available in JS:', this.message);
  }
})

new Vue({
  el: '#app',
  data: {
    variableAtParent: 'DATA FROM PARENT!'
  }
})

<script src="https://unpkg.com/[email protected]/dist/vue.min.js"></script>

<div id="app">
  <p>At Parent: {{ variableAtParent }}<br>And is reactive (edit it) <input v-model="variableAtParent"></p>
  <child-comp :message="variableAtParent"></child-comp>
</div>

Yep, you'll want to do something like this:

echo -n "Enter Fullname: " 
read fullname

Another option would be to have them supply this information on the command line. Getopts is your best bet there.

Using getopts in bash shell script to get long and short command line options

lsyncd seem to be nice alternative to the sshfs approach. If you use "-delay 0" it works in real-time.

To build upon @pozs's answers, here are a couple more PostgreSQL functions which may be useful to some. (Requires PostgreSQL 9.3+)

Delete By Key: Deletes a value from JSON structure by key.

CREATE OR REPLACE FUNCTION "json_object_del_key"(
  "json"          json,
  "key_to_del"    TEXT
)
  RETURNS json
  LANGUAGE sql
  IMMUTABLE
  STRICT
AS $function$
SELECT CASE
  WHEN ("json" -> "key_to_del") IS NULL THEN "json"
  ELSE (SELECT concat('{', string_agg(to_json("key") || ':' || "value", ','), '}')
          FROM (SELECT *
                  FROM json_each("json")
                 WHERE "key" <> "key_to_del"
               ) AS "fields")::json
END
$function$;

Recursive Delete By Key: Deletes a value from JSON structure by key-path. (requires @pozs's json_object_set_key function)

CREATE OR REPLACE FUNCTION "json_object_del_path"(
  "json"          json,
  "key_path"      TEXT[]
)
  RETURNS json
  LANGUAGE sql
  IMMUTABLE
  STRICT
AS $function$
SELECT CASE
  WHEN ("json" -> "key_path"[l] ) IS NULL THEN "json"
  ELSE
     CASE COALESCE(array_length("key_path", 1), 0)
         WHEN 0 THEN "json"
         WHEN 1 THEN "json_object_del_key"("json", "key_path"[l])
         ELSE "json_object_set_key"(
           "json",
           "key_path"[l],
           "json_object_del_path"(
             COALESCE(NULLIF(("json" -> "key_path"[l])::text, 'null'), '{}')::json,
             "key_path"[l+1:u]
           )
         )
       END
    END
  FROM array_lower("key_path", 1) l,
       array_upper("key_path", 1) u
$function$;

Usage examples:

s1=# SELECT json_object_del_key ('{"hello":[7,3,1],"foo":{"mofu":"fuwa", "moe":"kyun"}}',
                                 'foo'),
            json_object_del_path('{"hello":[7,3,1],"foo":{"mofu":"fuwa", "moe":"kyun"}}',
                                 '{"foo","moe"}');

 json_object_del_key |          json_object_del_path
---------------------+-----------------------------------------
 {"hello":[7,3,1]}   | {"hello":[7,3,1],"foo":{"mofu":"fuwa"}}

The other option is that if you have a filter that you always want applied, to add a custom manager on the model in question which always applies the filter to the results returned.

A good example of this is a Event model, where for 90% of the queries you do on the model you are going to want something like Event.objects.filter(date__gte=now), i.e. you're normally interested in Events that are upcoming. This would look like:

class EventManager(models.Manager):
    def get_query_set(self):
        now = datetime.now()
        return super(EventManager,self).get_query_set().filter(date__gte=now)

And in the model:

class Event(models.Model):
    ...
    objects = EventManager()

But again, this applies the same filter against all default queries done on the Event model and so isn't as flexible some of the techniques described above.

For merging first branch to second one:

on first branch: git merge secondBranch

on second branch: Move to first branch-> git checkout firstBranch-> git merge secondBranch

A simple way of keeping the values of fields in different fragments in an activity

Create the Instances of fragments and add instead of replace and remove

    FragA  fa= new FragA();
    FragB  fb= new FragB();
    FragC  fc= new FragB();
    fragmentManager = getSupportFragmentManager();
    fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.add(R.id.fragmnt_container, fa);
    fragmentTransaction.add(R.id.fragmnt_container, fb);
    fragmentTransaction.add(R.id.fragmnt_container, fc);
    fragmentTransaction.show(fa);
    fragmentTransaction.hide(fb);
    fragmentTransaction.hide(fc);
    fragmentTransaction.commit();

Then just show and hide the fragments instead of adding and removing those again

    fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.hide(fa);
    fragmentTransaction.show(fb);
    fragmentTransaction.hide(fc);
    fragmentTransaction.commit()

;

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

I think you want to set the response of the call to the URL 'compz.php?prodid=' + x + '&qbuys=' + y as value of the textbox right? If so, you have to do something like:

$.get('compz.php?prodid=' + x + '&qbuys=' + y, function(data) {
    $('#subtotal').val(data);
});

Reference: get()

You have two errors in your code:

• load() puts the HTML returned from the Ajax into the specified element:

  Load data from the server and place the returned HTML into the matched element.

  You cannot set the value of a textbox with that method.

• $(selector).load() returns the a jQuery object. By default an object is converted to [object Object] when treated as string.

Further clarification:

Assuming your URL returns 5.

If your HTML looks like:

<div id="foo"></div>

then the result of

$('#foo').load('/your/url');

will be

<div id="foo">5</div>

But in your code, you have an input element. Theoretically (it is not valid HTML and does not work as you noticed), an equivalent call would result in

<input id="foo">5</input>

But you actually need

<input id="foo" value="5" />

Therefore, you cannot use load(). You have to use another method, get the response and set it as value yourself.

This is the solution that I've came up with:

<form name = "form1" id = "form1" action = "#" method = "post">
  <select name = "DropDownList1" id = "DropDownList1">
<?php
$arr = array('Yes', 'No', 'Fine' ); // create array so looping is easier
for( $i = 1; $i <= 3; $i++ ) // loop starts at first value and ends at last value
{
  $selected = ''; // keep selected at nothing
  if( isset( $_POST['go'] ) ) // check if form was submitted
  {
    if( $_POST['DropDownList1'] == $i ) // if the value of the dropdownlist is equal to the looped variable
    {
      $selected = 'selected = "selected"'; // if is equal, set selected = "selected"
    }
  }
  // note: if value is not equal, selected stays defaulted to nothing as explained earlier
  echo '<option value = "' . $i . '"' . $selected . '>' . $arr[$i] . '</option>'; // echo the option element to the page using the $selected variable
}
?>
  </select> <!-- finish the form in html -->
  <input type="text" value="" name="name">
  <input type="submit" value="go" name="go">
</form>

The code I have works as long as the values are integers in some numeric order ( ascending or descending ). What it does is starts the dropdownlist in html, and adds each option element in php code. It will not work if you have random values though, i.e: 1, 4, 2, 7, 6. Each value must be unique.

Solution for JUnit 5

The documentation says:

However, JUnit Jupiter’s org.junit.jupiter.Assertions class does not provide an assertThat() method like the one found in JUnit 4’s org.junit.Assert class which accepts a Hamcrest Matcher. Instead, developers are encouraged to use the built-in support for matchers provided by third-party assertion libraries.

Example for Hamcrest:

import static org.hamcrest.CoreMatchers.instanceOf;
import static org.hamcrest.MatcherAssert.assertThat;

import org.junit.jupiter.api.Test;

class HamcrestAssertionDemo {

    @Test
    void assertWithHamcrestMatcher() {
        SubClass subClass = new SubClass();
        assertThat(subClass, instanceOf(BaseClass.class));
    }

}

Example for AssertJ:

import static org.assertj.core.api.Assertions.assertThat;

import org.junit.jupiter.api.Test;

class AssertJDemo {

    @Test
    void assertWithAssertJ() {
        SubClass subClass = new SubClass();
        assertThat(subClass).isInstanceOf(BaseClass.class);
    }

}

Note that this assumes you want to test behaviors similar to instanceof (which accepts subclasses). If you want exact equal type, I don’t see a better way than asserting the two class to be equal like you mentioned in the question.

If you use "suffixIcon" to collapse the height of the TextField add: suffixIconConstraints

TextField(
                    style: TextStyle(fontSize: r * 1.8, color: Colors.black87),
                    decoration: InputDecoration(
                      isDense: true,
                      contentPadding: EdgeInsets.symmetric(vertical: r * 1.6, horizontal: r * 1.6),
                      suffixIcon: Icon(Icons.search, color: Colors.black54),
                      suffixIconConstraints: BoxConstraints(minWidth: 32, minHeight: 32),
                    ),
                  )

I made a bash function that handle that. Here is the Github repo.

For record:

# Look for closest .gitconfig file in parent directories
# This file will be used as main .gitconfig file.
function __recursive_gitconfig_git {
    gitconfig_file=$(__recursive_gitconfig_closest)
    if [ "$gitconfig_file" != '' ]; then
        home="$(dirname $gitconfig_file)/"
        HOME=$home /usr/bin/git "$@"
    else
        /usr/bin/git "$@"
    fi
}

# Look for closest .gitconfig file in parents directories
function __recursive_gitconfig_closest {
    slashes=${PWD//[^\/]/}
    directory="$PWD"
    for (( n=${#slashes}; n>0; --n ))
    do
        test -e "$directory/.gitconfig" && echo "$directory/.gitconfig" && return 
        directory="$directory/.."
    done
}


alias git='__recursive_gitconfig_git'

I was using the Runnable with sv.fullScroll(View.FOCUS_DOWN); It works perfectly for the immediate problem, but that method makes ScrollView take the Focus from the entire screen, if you make that AutoScroll to happen every time, no EditText will be able to receive information from the user, my solution was use a different code under the runnable:

sv.scrollTo(0, sv.getBottom() + sv.getScrollY());

making the same without losing focus on important views

greetings.

Another approach I found is to set a delegate for the NavigationController:

navigationController.delegate = self;

and use setNavigationBarHidden in navigationController:willShowViewController:animated:

- (void)navigationController:(UINavigationController *)navigationController 
      willShowViewController:(UIViewController *)viewController 
                    animated:(BOOL)animated 
{   
    // Hide the nav bar if going home.
    BOOL hide = viewController != homeViewController;
    [navigationController setNavigationBarHidden:hide animated:animated];
}

Easy way to customize the behavior for each ViewController all in one place.

This work around will fix the issue found by @Cletus.

function submitForm(form) {
    //get the form element's document to create the input control with
    //(this way will work across windows in IE8)
    var button = form.ownerDocument.createElement('input');
    //make sure it can't be seen/disrupts layout (even momentarily)
    button.style.display = 'none';
    //make it such that it will invoke submit if clicked
    button.type = 'submit';
    //append it and click it
    form.appendChild(button).click();
    //if it was prevented, make sure we don't get a build up of buttons
    form.removeChild(button);
}

Will work on all modern browsers.
Will work across tabs/spawned child windows (yes, even in IE<9).
And is in vanilla!

Just pass it a DOM reference to a form element and it'll make sure all the attached listeners, the onsubmit, and (if its not prevented by then) finally, submit the form.

This is actually a bit of a perpetuated falsehood. While it is true that C programs are frequently faster, this is not always the case, especially if the C programmer isn't very good at it.

One big glaring hole that people tend to forget about is when the program has to block for some sort of IO, such as user input in any GUI program. In these cases, it doesn't really matter what language you use since you are limited by the rate at which data can come in rather than how fast you can process it. In this case, it doesn't matter much if you are using C, Java, C# or even Perl; you just cannot go any faster than the data can come in.

The other major thing is that using garbage collection and not using proper pointers allows the virtual machine to make a number of optimizations not available in other languages. For instance, the JVM is capable of moving objects around on the heap to defragment it. This makes future allocations much faster since the next index can simply be used rather than looking it up in a table. Modern JVMs also don't have to actually deallocate memory; instead, they just move the live objects around when they GC and the spent memory from the dead objects is recovered essentially for free.

This also brings up an interesting point about C and even more so in C++. There is something of a design philosophy of "If you don't need it, you don't pay for it." The problem is that if you do want it, you end up paying through the nose for it. For instance, the vtable implementation in Java tends to be a lot better than C++ implementations, so virtual function calls are a lot faster. On the other hand, you have no choice but to use virtual functions in Java and they still cost something, but in programs that use a lot of virtual functions, the reduced cost adds up.

To print the text my text you can use either of the following Locator Strategies:

• Using class_name and get_attribute("textContent"):

  print(driver.find_element(By.CLASS_NAME, "current-stage").get_attribute("textContent"))
  

• Using css_selector and get_attribute("innerHTML"):

  print(driver.find_element(By.CSS_SELECTOR, "span.current-stage").get_attribute("innerHTML"))
  

• Using xpath and text attribute:

  print(driver.find_element(By.XPATH, "//span[@class='current-stage']").text)
  

Ideally you need to induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies:

• Using CLASS_NAME and get_attribute("textContent"):

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CLASS_NAME, "current-stage"))).get_attribute("textContent"))
  

• Using CSS_SELECTOR and text attribute:

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "span.current-stage"))).text)
  

• Using XPATH and get_attribute("innerHTML"):

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//span[@class='current-stage']"))).get_attribute("innerHTML"))
  

• Note : You have to add the following imports :

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC

template system, useful if you want to create colorful line text without creating full style for every block

var tpl = 'background-color:greenyellow; border:3px solid orange; font-size:18px; font-weight: bold;padding:3px 5px;color:';
console.log('%cNo #1' + '.%cRed Text' + '%cBlue Text', 
             tpl+'magenta', tpl+'red', tpl+'blue');

I tried /etc/profile, ~/.profile and ~/.bash_profile and none of those worked. I found that editing ~/.bashrc for the jenkins slave account did.

You need to reference the namespace

using System.Windows.Form;

and then add in the code

protected void Button1_Click(object sender, EventArgs e)
    {
        MessageBox.Show(" Hi....");

    }

This is a known issue in BS 3 - https://github.com/twbs/bootstrap/issues/9862?source=cc

I have tested on Bootply using the latest build, so keep watching GitHub for the latest updates/fix.

In Bootstrap 3, .row is must be used inside a .container or .container-fluid to counteract the negative margins on the row. This will eliminate the horizontal scrollbar.

From the docs...

"Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding."

Bootstrap 4

The container>row>col relationship work the same way as 3.x...

"Containers are the most basic layout element in Bootstrap and are required when using our default grid system"

A more up to date solution, for encoding:

// This is the same for all of the below, and
// you probably won't need it except for debugging
// in most cases.
function bytesToHex(bytes) {
  return Array.from(
    bytes,
    byte => byte.toString(16).padStart(2, "0")
  ).join("");
}

// You almost certainly want UTF-8, which is
// now natively supported:
function stringToUTF8Bytes(string) {
  return new TextEncoder().encode(string);
}

// But you might want UTF-16 for some reason.
// .charCodeAt(index) will return the underlying
// UTF-16 code-units (not code-points!), so you
// just need to format them in whichever endian order you want.
function stringToUTF16Bytes(string, littleEndian) {
  const bytes = new Uint8Array(string.length * 2);
  // Using DataView is the only way to get a specific
  // endianness.
  const view = new DataView(bytes.buffer);
  for (let i = 0; i != string.length; i++) {
    view.setUint16(i, string.charCodeAt(i), littleEndian);
  }
  return bytes;
}

// And you might want UTF-32 in even weirder cases.
// Fortunately, iterating a string gives the code
// points, which are identical to the UTF-32 encoding,
// though you still have the endianess issue.
function stringToUTF32Bytes(string, littleEndian) {
  const codepoints = Array.from(string, c => c.codePointAt(0));
  const bytes = new Uint8Array(codepoints.length * 4);
  // Using DataView is the only way to get a specific
  // endianness.
  const view = new DataView(bytes.buffer);
  for (let i = 0; i != codepoints.length; i++) {
    view.setUint32(i, codepoints[i], littleEndian);
  }
  return bytes;
}

Examples:

bytesToHex(stringToUTF8Bytes("hello ?? "))
// "68656c6c6f20e6bca2e5ad9720f09f918d"
bytesToHex(stringToUTF16Bytes("hello ?? ", false))
// "00680065006c006c006f00206f225b570020d83ddc4d"
bytesToHex(stringToUTF16Bytes("hello ?? ", true))
// "680065006c006c006f002000226f575b20003dd84ddc"
bytesToHex(stringToUTF32Bytes("hello ?? ", false))
// "00000068000000650000006c0000006c0000006f0000002000006f2200005b57000000200001f44d"
bytesToHex(stringToUTF32Bytes("hello ?? ", true))
// "68000000650000006c0000006c0000006f00000020000000226f0000575b0000200000004df40100"

For decoding, it's generally a lot simpler, you just need:

function hexToBytes(hex) {
    const bytes = new Uint8Array(hex.length / 2);
    for (let i = 0; i !== bytes.length; i++) {
        bytes[i] = parseInt(hex.substr(i * 2, 2), 16);
    }
    return bytes;
}

then use the encoding parameter of TextDecoder:

// UTF-8 is default
new TextDecoder().decode(hexToBytes("68656c6c6f20e6bca2e5ad9720f09f918d"));
// but you can also use:
new TextDecoder("UTF-16LE").decode(hexToBytes("680065006c006c006f002000226f575b20003dd84ddc"))
new TextDecoder("UTF-16BE").decode(hexToBytes("00680065006c006c006f00206f225b570020d83ddc4d"));
// "hello ?? "

Here's the list of allowed encoding names: https://www.w3.org/TR/encoding/#names-and-labels

You might notice UTF-32 is not on that list, which is a pain, so:

function bytesToStringUTF32(bytes, littleEndian) {
  const view = new DataView(bytes.buffer);
  const codepoints = new Uint32Array(view.byteLength / 4);
  for (let i = 0; i !== codepoints.length; i++) {
    codepoints[i] = view.getUint32(i * 4, littleEndian);
  }
  return String.fromCodePoint(...codepoints);
}

Then:

bytesToStringUTF32(hexToBytes("00000068000000650000006c0000006c0000006f0000002000006f2200005b57000000200001f44d"), false)
bytesToStringUTF32(hexToBytes("68000000650000006c0000006c0000006f00000020000000226f0000575b0000200000004df40100"), true)
// "hello ?? "

Software application written with Arduino, an IDE used for prototyping electronics; contains source code written in the Arduino programming language; enables developers to control the electronics on an Arduino circuit board.

To avoid file association conflicts with the Processing software, Arduino changed the Sketch file extension to .INO with the version 1.0 release. Therefore, while Arduino can still open ".pde" files, the ".ino" file extension should be used instead.

Each PDE file is stored in its own folder when saved from the Processing IDE. It is saved with any other program assets, such as images. The project folder and PDE filename prefix have the same name. When the PDE file is run, it is opened in a Java display window, which renders and runs the resulting program.

Processing is commonly used in educational settings for teaching basic programming skills in a visual environment.

You can use simple trick which is import flask app variable from main inside another file, like:

test-routes.py

from __main__ import app

@app.route('/test', methods=['GET'])
def test():
    return 'it works!'

and in your main files, where you declared flask app, import test-routes, like:

app.py

from flask import Flask, request, abort

app = Flask(__name__)

# import declared routes
import test-routes

It works from my side.

I think there is a lot of confusion about which weights are used for what. I am not sure I know precisely what bothers you so I am going to cover different topics, bear with me ;).

Class weights

The weights from the class_weight parameter are used to train the classifier. They are not used in the calculation of any of the metrics you are using: with different class weights, the numbers will be different simply because the classifier is different.

Basically in every scikit-learn classifier, the class weights are used to tell your model how important a class is. That means that during the training, the classifier will make extra efforts to classify properly the classes with high weights.
How they do that is algorithm-specific. If you want details about how it works for SVC and the doc does not make sense to you, feel free to mention it.

The metrics

Once you have a classifier, you want to know how well it is performing. Here you can use the metrics you mentioned: accuracy, recall_score, f1_score...

Usually when the class distribution is unbalanced, accuracy is considered a poor choice as it gives high scores to models which just predict the most frequent class.

I will not detail all these metrics but note that, with the exception of accuracy, they are naturally applied at the class level: as you can see in this print of a classification report they are defined for each class. They rely on concepts such as true positives or false negative that require defining which class is the positive one.

             precision    recall  f1-score   support

          0       0.65      1.00      0.79        17
          1       0.57      0.75      0.65        16
          2       0.33      0.06      0.10        17
avg / total       0.52      0.60      0.51        50

The warning

F1 score:/usr/local/lib/python2.7/site-packages/sklearn/metrics/classification.py:676: DeprecationWarning: The 
default `weighted` averaging is deprecated, and from version 0.18, 
use of precision, recall or F-score with multiclass or multilabel data  
or pos_label=None will result in an exception. Please set an explicit 
value for `average`, one of (None, 'micro', 'macro', 'weighted', 
'samples'). In cross validation use, for instance, 
scoring="f1_weighted" instead of scoring="f1".

You get this warning because you are using the f1-score, recall and precision without defining how they should be computed! The question could be rephrased: from the above classification report, how do you output one global number for the f1-score? You could:

1. Take the average of the f1-score for each class: that's the avg / total result above. It's also called macro averaging.
2. Compute the f1-score using the global count of true positives / false negatives, etc. (you sum the number of true positives / false negatives for each class). Aka micro averaging.
3. Compute a weighted average of the f1-score. Using 'weighted' in scikit-learn will weigh the f1-score by the support of the class: the more elements a class has, the more important the f1-score for this class in the computation.

These are 3 of the options in scikit-learn, the warning is there to say you have to pick one. So you have to specify an average argument for the score method.

Which one you choose is up to how you want to measure the performance of the classifier: for instance macro-averaging does not take class imbalance into account and the f1-score of class 1 will be just as important as the f1-score of class 5. If you use weighted averaging however you'll get more importance for the class 5.

The whole argument specification in these metrics is not super-clear in scikit-learn right now, it will get better in version 0.18 according to the docs. They are removing some non-obvious standard behavior and they are issuing warnings so that developers notice it.

Computing scores

Last thing I want to mention (feel free to skip it if you're aware of it) is that scores are only meaningful if they are computed on data that the classifier has never seen. This is extremely important as any score you get on data that was used in fitting the classifier is completely irrelevant.

Here's a way to do it using StratifiedShuffleSplit, which gives you a random splits of your data (after shuffling) that preserve the label distribution.

from sklearn.datasets import make_classification
from sklearn.cross_validation import StratifiedShuffleSplit
from sklearn.metrics import accuracy_score, f1_score, precision_score, recall_score, classification_report, confusion_matrix

# We use a utility to generate artificial classification data.
X, y = make_classification(n_samples=100, n_informative=10, n_classes=3)
sss = StratifiedShuffleSplit(y, n_iter=1, test_size=0.5, random_state=0)
for train_idx, test_idx in sss:
    X_train, X_test, y_train, y_test = X[train_idx], X[test_idx], y[train_idx], y[test_idx]
    svc.fit(X_train, y_train)
    y_pred = svc.predict(X_test)
    print(f1_score(y_test, y_pred, average="macro"))
    print(precision_score(y_test, y_pred, average="macro"))
    print(recall_score(y_test, y_pred, average="macro"))    

Hope this helps.

Try IndexOf.

You just add one additional row before you execute the loop. This row contains your CSV file header name.

schema = ['a','b','c','b']
row = 4
generators = ['A','B','C','D']
with open('test.csv','wb') as csvfile:    
     writer = csv.writer(csvfile, delimiter=delimiter)
# Gives the header name row into csv
     writer.writerow([g for g in schema])   
#Data add in csv file       
     for x in xrange(rows):
         writer.writerow([g() for g in generators])

Using a classmethod with __members__:

class RoleNames(str, Enum):
    AGENT = "agent"
    USER = "user"
    PRIMARY_USER = "primary_user"
    SUPER_USER = "super_user"
    
    @classmethod
    def list_roles(cls):

        return role_names

>>> role_names = RoleNames.list_roles()
>>> print(role_names)

or if you have multiple Enum classes and want to abstract the classmethod:

class BaseEnum(Enum):
    @classmethod
    def list_roles(cls):
        role_names = [member.value for role, member in cls.__members__.items()]
        return role_names

    USER = "user"
    PRIMARY_USER = "primary_user"
    SUPER_USER = "super_user"
    

class PermissionNames(str, BaseEnum):
    READ = "updated_at"
    WRITE = "sort_by"
    READ_WRITE = "sort_order"

I do not understand why the answers are so complex. In Javascript, primitives (strings, numbers, etc) are passed by value, and copied. Objects, including arrays, are passed by reference. In any case, assignment of a new value or object reference to 'a' will not change 'b'. But changing the contents of 'a' will change the contents of 'b'.

var a = 'a'; var b = a; a = 'c'; // b === 'a'

var a = {a:'a'}; var b = a; a = {c:'c'}; // b === {a:'a'} and a = {c:'c'}

var a = {a:'a'}; var b = a; a.a = 'c'; // b.a === 'c' and a.a === 'c'

Paste any of the above lines (one at a time) into node or any browser javascript console. Then type any variable and the console will show it's value.

I often ended up doing things like this. Therefore I tried to write a simple function that 'snips' out the unwanted elements in an easy way. This turns matlab logic a bit upside down, but looks good:

It also works with all other 'x', nan or whatever elements.

Some insight into why concat works on the example but not this data would be nice though!

Your resource methods won't get hit, so their headers will never get set. The reason is that there is what's called a preflight request before the actual request, which is an OPTIONS request. So the error comes from the fact that the preflight request doesn't produce the necessary headers.

For RESTeasy, you should use CorsFilter. You can see here for some example how to configure it. This filter will handle the preflight request. So you can remove all those headers you have in your resource methods.

Yesterday, I shortened the code (just added <Provider store={store}>) and still got this invalid hook call problem. This made me suddenly realized what mistake I did: I didn't install the react-redux software in that folder.

I had installed this software in the other project folder, so I didn't realize this one also needed it. After installing it, the error is gone.

Define a variable in .bashrc :

export C=/cygdrive/c

then you can use

and the tab autocompletes correctly (please include the / at the end)

Call the continuation with TaskScheduler.FromCurrentSynchronizationContext():

    Task UITask= task.ContinueWith(() =>

     this.TextBlock1.Text = "Complete"; 
    }, TaskScheduler.FromCurrentSynchronizationContext());

This is suitable only if the current execution context is on the UI thread.

try setting the display to block in your javascript instead of a blank value.

I would try to set a flag on the window.onfocus and window.onblur events.

The following snippet has been tested on Firefox, Safari and Chrome, open the console and move between tabs back and forth:

var isTabActive;

window.onfocus = function () { 
  isTabActive = true; 
}; 

window.onblur = function () { 
  isTabActive = false; 
}; 

// test
setInterval(function () { 
  console.log(window.isTabActive ? 'active' : 'inactive'); 
}, 1000);

Try it out here.

A little late to the party, but this worked for me. Hopefully someone else finds it useful.

$('.popup-ajax').mouseout(function() {

I understood your question I think you are confusing it with languages like dot.net and java where you can open DB connection within your code. No, JavaScript can not directly connect to MySQL as JavaScript is a client side scripting language(Exception Node.js).You need a middle layer like RESTful API to access data.

You could easily do it with an IntStream and the max() method.

Example

public static int maxValue(final int[] intArray) {
  return IntStream.range(0, intArray.length).map(i -> intArray[i]).max().getAsInt();
}

Explanation

1. range(0, intArray.length) - To get a stream with as many elements as present in the intArray.

2. map(i -> intArray[i]) - Map every element of the stream to an actual element of the intArray.

3. max() - Get the maximum element of this stream as OptionalInt.

4. getAsInt() - Unwrap the OptionalInt. (You could also use here: orElse(0), just in case the OptionalInt is empty.)

Do use NULL. It is just #defined as 0 anyway and it is very useful to semantically distinguish it from the integer 0.

There are problems with using 0 (and hence NULL). For example:

void f(int);
void f(void*);

f(0); // Ambiguous. Calls f(int).

The next version of C++ (C++0x) includes nullptr to fix this.

f(nullptr); // Calls f(void*).

The thing to watch out for when writing C++ dlls is name mangling. If you want interoperability between C and C++, you'd be better off by exporting non-mangled C-style functions from within the dll.

You have two options to use a dll

• Either use a lib file to link the symbols -- compile time dynamic linking
• Use LoadLibrary() or some suitable function to load the library, retrieve a function pointer (GetProcAddress) and call it -- runtime dynamic linking

Exporting classes will not work if you follow the second method though.

"UPDATE TableName SET TableField = TableField + 1 WHERE SomeFilterField = @ParameterID"

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Here is a minimal example of how @property can be implemented:

class Thing:
    def __init__(self, my_word):
        self._word = my_word 
    @property
    def word(self):
        return self._word

>>> print( Thing('ok').word )
'ok'

Otherwise word remains a method instead of a property.

class Thing:
    def __init__(self, my_word):
        self._word = my_word
    def word(self):
        return self._word

>>> print( Thing('ok').word() )
'ok'

fig = plt.figure()
ax = fig.add_subplot(111)
plt.xticks([0.4,0.14,0.2,0.2], fontsize = 50) # work on current fig
plt.show()

the x/yticks has the same properties as matplotlib.text

EDIT: If all your keys are strings, then before continuing to read this answer, please see Jack O'Connor's significantly simpler (and faster) solution (which also works for hashing nested dictionaries).

Although an answer has been accepted, the title of the question is "Hashing a python dictionary", and the answer is incomplete as regards that title. (As regards the body of the question, the answer is complete.)

Nested Dictionaries

If one searches Stack Overflow for how to hash a dictionary, one might stumble upon this aptly titled question, and leave unsatisfied if one is attempting to hash multiply nested dictionaries. The answer above won't work in this case, and you'll have to implement some sort of recursive mechanism to retrieve the hash.

Here is one such mechanism:

import copy

def make_hash(o):

  """
  Makes a hash from a dictionary, list, tuple or set to any level, that contains
  only other hashable types (including any lists, tuples, sets, and
  dictionaries).
  """

  if isinstance(o, (set, tuple, list)):

    return tuple([make_hash(e) for e in o])    

  elif not isinstance(o, dict):

    return hash(o)

  new_o = copy.deepcopy(o)
  for k, v in new_o.items():
    new_o[k] = make_hash(v)

  return hash(tuple(frozenset(sorted(new_o.items()))))

Bonus: Hashing Objects and Classes

The hash() function works great when you hash classes or instances. However, here is one issue I found with hash, as regards objects:

class Foo(object): pass
foo = Foo()
print (hash(foo)) # 1209812346789
foo.a = 1
print (hash(foo)) # 1209812346789

The hash is the same, even after I've altered foo. This is because the identity of foo hasn't changed, so the hash is the same. If you want foo to hash differently depending on its current definition, the solution is to hash off whatever is actually changing. In this case, the __dict__ attribute:

class Foo(object): pass
foo = Foo()
print (make_hash(foo.__dict__)) # 1209812346789
foo.a = 1
print (make_hash(foo.__dict__)) # -78956430974785

Alas, when you attempt to do the same thing with the class itself:

print (make_hash(Foo.__dict__)) # TypeError: unhashable type: 'dict_proxy'

The class __dict__ property is not a normal dictionary:

print (type(Foo.__dict__)) # type <'dict_proxy'>

Here is a similar mechanism as previous that will handle classes appropriately:

import copy

DictProxyType = type(object.__dict__)

def make_hash(o):

  """
  Makes a hash from a dictionary, list, tuple or set to any level, that 
  contains only other hashable types (including any lists, tuples, sets, and
  dictionaries). In the case where other kinds of objects (like classes) need 
  to be hashed, pass in a collection of object attributes that are pertinent. 
  For example, a class can be hashed in this fashion:

    make_hash([cls.__dict__, cls.__name__])

  A function can be hashed like so:

    make_hash([fn.__dict__, fn.__code__])
  """

  if type(o) == DictProxyType:
    o2 = {}
    for k, v in o.items():
      if not k.startswith("__"):
        o2[k] = v
    o = o2  

  if isinstance(o, (set, tuple, list)):

    return tuple([make_hash(e) for e in o])    

  elif not isinstance(o, dict):

    return hash(o)

  new_o = copy.deepcopy(o)
  for k, v in new_o.items():
    new_o[k] = make_hash(v)

  return hash(tuple(frozenset(sorted(new_o.items()))))

You can use this to return a hash tuple of however many elements you'd like:

# -7666086133114527897
print (make_hash(func.__code__))

# (-7666086133114527897, 3527539)
print (make_hash([func.__code__, func.__dict__]))

# (-7666086133114527897, 3527539, -509551383349783210)
print (make_hash([func.__code__, func.__dict__, func.__name__]))

NOTE: all of the above code assumes Python 3.x. Did not test in earlier versions, although I assume make_hash() will work in, say, 2.7.2. As far as making the examples work, I do know that

func.__code__ 

should be replaced with

func.func_code

According to a quick google search, this update only applies to the current shell you have open. It can probably be fixed by typing python3, as mac and linux are similar enough for things like this to coincide. Link to the result of google search.

Also, as ninjagecko stated, most programs have not been updated to 3.x yet, so having the default python as 3.x would break many python scripts used in applications.
