An Event declaration adds a layer of abstraction and protection on the delegate instance. This protection prevents clients of the delegate from resetting the delegate and its invocation list and only allows adding or removing targets from the invocation list.

It would be something like this

function CustomInputBox([string] $title, [string] $message, [string] $defaultText) 
{
$inputObject = new-object -comobject MSScriptControl.ScriptControl
$inputObject.language = "vbscript" 
$inputObject.addcode("function getInput() getInput = inputbox(`"$message`",`"$title`" , `"$defaultText`") end function" ) 
$_userInput = $inputObject.eval("getInput") 

return $_userInput
}

Then you can call the function similar to this.

$userInput = CustomInputBox "User Name" "Please enter your name." ""
if ( $userInput -ne $null ) 
{
 echo "Input was [$userInput]"
}
else
{
 echo "User cancelled the form!"
}

This is the most simple way to do this that I can think of.

Just use multiline selection in sublime to combine all of the files into a single line and add a space between each file name and then add rm at the beginning of the list. This is mostly useful when there isn't a pattern in the filenames you want to delete.

[$]> rm abc.log.2012-03-14 abc.log.2012-03-27 abc.log.2012-03-28 abc.log.2012-03-29 abc.log.2012-03-30 abc.log.2012-04-02 abc.log.2012-04-04 abc.log.2012-04-05 abc.log.2012-04-09 abc.log.2012-04-10

Most people use docker compose with networks. The documentation states:

The Docker network feature supports creating networks without the need to expose ports within the network, for detailed information see the overview of this feature).

Which means that if you use networks for communication between containers you don't need to worry about exposing ports.

I think that coreset.o was compiled for 64-bit, and you are linking it with a 32-bit computation.o.

You can try to recompile computation.c with the '-m64' flag of gcc(1)

simply use this in your imagebutton layout

android:background="@null"

using

 android:background="@android:color/transparent 

or

 btn.setBackgroundColor(Color.TRANSPARENT);

doesn't give perfect transparency

Simply running easy_install -U pip resolved my problem.

I'm not sure about what you mean by "I have no access to image" But if you have access to parent div you can do the following:

Firs give id or class to your div:

<div class="parent">
   <img src="http://someimage.jpg">
</div>

Than add this to your css:

.parent {
   width: 42px; /* I took the width from your post and placed it in css */
   height: 42px;
}

/* This will style any <img> element in .parent div */
.parent img {
   height: 100%;
   width: 100%;
}

<string-array name="array_name">
<item>Array Item One</item>
<item>Array Item Two</item>
<item>Array Item Three</item>
</string-array>

In your layout:

<Spinner 
        android:id="@+id/spinner"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:drawSelectorOnTop="true"
        android:entries="@array/array_name"
    />

length and dbms_lob.getlength return the number of characters when applied to a CLOB (Character LOB). When applied to a BLOB (Binary LOB), dbms_lob.getlength will return the number of bytes, which may differ from the number of characters in a multi-byte character set.

As the documentation doesn't specify what happens when you apply length on a BLOB, I would advise against using it in that case. If you want the number of bytes in a BLOB, use dbms_lob.getlength.

If you do not have access to the TestRunner type information in the calling assembly (it sounds like you may not), you can call the method like this:

Assembly assembly = Assembly.LoadFile(@"C:\dyn.dll");
Type     type     = assembly.GetType("TestRunner");
var      obj      = Activator.CreateInstance(type);

// Alternately you could get the MethodInfo for the TestRunner.Run method
type.InvokeMember("Run", 
                  BindingFlags.Default | BindingFlags.InvokeMethod, 
                  null,
                  obj,
                  null);

If you have access to the IRunnable interface type, you can cast your instance to that (rather than the TestRunner type, which is implemented in the dynamically created or loaded assembly, right?):

  Assembly assembly  = Assembly.LoadFile(@"C:\dyn.dll");
  Type     type      = assembly.GetType("TestRunner");
  IRunnable runnable = Activator.CreateInstance(type) as IRunnable;
  if (runnable == null) throw new Exception("broke");
  runnable.Run();

You can create an extension function similar to java.util.Random.nextInt(int) but one that takes an IntRange instead of an Int for its bound:

fun Random.nextInt(range: IntRange): Int {
    return range.start + nextInt(range.last - range.start)
}

You can now use this with any Random instance:

val random = Random()
println(random.nextInt(5..9)) // prints 5, 6, 7, 8, or 9

If you don't want to have to manage your own Random instance then you can define a convenience method using, for example, ThreadLocalRandom.current():

fun rand(range: IntRange): Int {
    return ThreadLocalRandom.current().nextInt(range)
}

Now you can get a random integer as you would in Ruby without having to first declare a Random instance yourself:

rand(5..9) // returns 5, 6, 7, 8, or 9

In python3 with virtualenv on a Ubuntu Bionic machine the following commands worked for me:

sudo apt install build-essential python-dev libmysqlclient-dev
sudo apt-get install libssl-dev
pip install mysqlclient

You are not returning anything, at least from your snippet and comment.

const def = (props) => { <div></div> };

This is not returning anything, you are wrapping the body of the arrow function with curly braces but there is no return value.

const def = (props) => { return (<div></div>); }; OR const def = (props) => <div></div>;

These two solutions on the other hand are returning a valid React component. Keep also in mind that inside your jsx (as mentioned by @Adam) you can't have if ... else ... but only ternary operators.

you should use []

var x = ConfigurationManager.AppSettings["APIKey"];

how about gets ?

myFile=File.open("paths_to_file","r")
while(line=myFile.gets)
 //do stuff with line
end

Although I'm not answering the original question concering the no-op command, many (if not most) problems when one may think "in this branch I have to do nothing" can be bypassed by simply restructuring the logic so that this branch won't occur.

I try to give a general rule by using the OPs example

do nothing when $a is greater than "10", print "1" if $a is less than "5", otherwise, print "2"

we have to avoid a branch where $a gets more than 10, so $a < 10 as a general condition can be applied to every other, following condition.

In general terms, when you say do nothing when X, then rephrase it as avoid a branch where X. Usually you can make the avoidance happen by simply negating X and applying it to all other conditions.

So the OPs example with the rule applied may be restructured as:

if [ "$a" -lt 10 ] && [ "$a" -le 5 ]
then
    echo "1"
elif [ "$a" -lt 10 ]
then
    echo "2"
fi

Just a variation of the above, enclosing everything in the $a < 10 condition:

if [ "$a" -lt 10 ]
then
    if [ "$a" -le 5 ]
    then
        echo "1"
    else
        echo "2"
    fi
fi

(For this specific example @Flimzys restructuring is certainly better, but I wanted to give a general rule for all the people searching how to do nothing.)

One possible explanation is a database trigger that fires for each DROP TABLE statement. To find the trigger, query the _TRIGGERS dictionary views:

select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')

disable any suspicious trigger with

   alter trigger <trigger_name> disable;

and try re-running your DROP TABLE statement

Say you have a class called MyFancyObject like this one below:

class MyFancyObject
{
 public int A { get;set;}
}

It lets you turn:

String ClassName = "MyFancyObject";

Into

MyFancyObject obj;

Using

obj = (MyFancyObject)Activator.CreateInstance("MyAssembly", ClassName))

and can then do stuff like:

obj.A = 100;

That's its purpose. It also has many other overloads such as providing a Type instead of the class name in a string. Why you would have a problem like that is a different story. Here's some people who needed it:

• Createinstance() - Am I doing this right?
• C# Using Activator.CreateInstance
• Creating an object without knowing the class name at design time

1.1) First-level cache

First-level cache always Associates with the Session object. Hibernate uses this cache by default. Here, it processes one transaction after another one, means wont process one transaction many times. Mainly it reduces the number of SQL queries it needs to generate within a given transaction. That is instead of updating after every modification done in the transaction, it updates the transaction only at the end of the transaction.

1.2) Second-level cache

Second-level cache always associates with the Session Factory object. While running the transactions, in between it loads the objects at the Session Factory level, so that those objects will be available to the entire application, not bound to single user. Since the objects are already loaded in the cache, whenever an object is returned by the query, at that time no need to go for a database transaction. In this way the second level cache works. Here we can use query level cache also.

Quoted from: http://javabeat.net/introduction-to-hibernate-caching/

I believe Double.NaN might be able to cover this. That is the only 'null' value double contains.

Learning to use smart pointers is in my opinion one of the most important steps to become a competent C++ programmer. As you know whenever you new an object at some point you want to delete it.

One issue that arise is that with exceptions it can be very hard to make sure a object is always released just once in all possible execution paths.

This is the reason for RAII: http://en.wikipedia.org/wiki/RAII

Making a helper class with purpose of making sure that an object always deleted once in all execution paths.

Example of a class like this is: std::auto_ptr

But sometimes you like to share objects with other. It should only be deleted when none uses it anymore.

In order to help with that reference counting strategies have been developed but you still need to remember addref and release ref manually. In essence this is the same problem as new/delete.

That's why boost has developed boost::shared_ptr, it's reference counting smart pointer so you can share objects and not leak memory unintentionally.

With the addition of C++ tr1 this is now added to the c++ standard as well but its named std::tr1::shared_ptr<>.

I recommend using the standard shared pointer if possible. ptr_list, ptr_dequeue and so are IIRC specialized containers for pointer types. I ignore them for now.

So we can start from your example:

std::vector<gate*> G; 
G.push_back(new ANDgate);  
G.push_back(new ORgate); 
for(unsigned i=0;i<G.size();++i) 
{ 
  G[i]->Run(); 
} 

The problem here is now that whenever G goes out scope we leak the 2 objects added to G. Let's rewrite it to use std::tr1::shared_ptr

// Remember to include <memory> for shared_ptr
// First do an alias for std::tr1::shared_ptr<gate> so we don't have to 
// type that in every place. Call it gate_ptr. This is what typedef does.
typedef std::tr1::shared_ptr<gate> gate_ptr;    
// gate_ptr is now our "smart" pointer. So let's make a vector out of it.
std::vector<gate_ptr> G; 
// these smart_ptrs can't be implicitly created from gate* we have to be explicit about it
// gate_ptr (new ANDgate), it's a good thing:
G.push_back(gate_ptr (new ANDgate));  
G.push_back(gate_ptr (new ORgate)); 
for(unsigned i=0;i<G.size();++i) 
{ 
   G[i]->Run(); 
} 

When G goes out of scope the memory is automatically reclaimed.

As an exercise which I plagued newcomers in my team with is asking them to write their own smart pointer class. Then after you are done discard the class immedietly and never use it again. Hopefully you acquired crucial knowledge on how a smart pointer works under the hood. There's no magic really.

Now there's no need to side load any packages of execute any scripts to get the Play Store on the emulator. Starting from Android Studio 2.4 now you can create an AVD that has Play Store pre-installed on it. Currently it is supported only on the AVDs running Android 7.0 (API 24) system images.

Try string.Remove();

Use of pointer before character array

Normally, Character array is used to store single elements in it i.e 1 byte each

eg:

char a[]={'a','b','c'};

we can't store multiple value in it.

by using pointer before the character array we can store the multi dimensional array elements in the array

i.e.

char *a[]={"one","two","three"};
printf("%s\n%s\n%s",a[0],a[1],a[2]);

First you need to up/start the all the redis nodes using below command, one by one for all conf files. @Note : if you are setting up cluster then you should have 6 nodes, 3 will be master and 3 will be slave.redis-cli will automatically select master and slave out of 6 nodes using --cluster command as shown in my below commands.

[xxxxx@localhost redis-stable]$ redis-server xxxx.conf 

then run

[xxxxx@localhost redis-stable]$ redis-cli --cluster create 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 --cluster-replicas 1

output of above should be like:

    >>> Performing hash slots allocation on 6 nodes...

2nd way to set up all things automatically: you can use utils/create-cluster scripts to set up every thing for you like starting all nodes, creating cluster you an follow https://redis.io/topics/cluster-tutorial

I have found simpler solution:

$('#clickToCreate').live('click', function() {
     $('#yourDialogId')
         .dialog({
              title: "Set the title to Create"
         })
         .dialog('open'); 
});


$('#clickToEdit').live('click', function() {
     $('#yourDialogId')
         .dialog({
              title: "Set the title To Edit"
         })
         .dialog('open'); 
});

Performance-wise, I found the ServiceStack's serializer a bit faster than then others. It's JsonSerializer class in ServiceStack.Text namespace.

ServiceStack is available through NuGet package: https://www.nuget.org/packages/ServiceStack/

It seems that you can use regexp too

WHERE NOT REGEXP_LIKE(field, '^Done|^Finished')

I'm not sure how well this will perform though ... see here

This is not a full answer, but the below code should help you:

function myFunction() {
    var str = "https://www.123rf.com/photo_10965738_lots-oop.html";
    matches = str.split('/');
    return matches[2];
}

I would like some one to create code faster than mine. It help to improve my-self also.

You are using .index() which will only find the first occurrence of your value in the list. So if you have a value 1.0 at index 2, and at index 9, then .index(1.0) will always return 2, no matter how many times 1.0 occurs in the list.

Use enumerate() to add indices to your loop instead:

def find(lst, a, b):
    result = []
    for i, x in enumerate(lst):
        if x<a or x>b:
            result.append(i)
    return result

You can collapse this into a list comprehension:

def find(lst, a, b):
    return [i for i, x in enumerate(lst) if x<a or x>b]

Use PtrSafe and see how that works on Excel 2010.

Pattern based configs are scheduled for 2.0.0 release of ESLint. For now, however, you will have to create two separate tasks (as mentioned in the comments). One for tests and one for the rest of the code and run both of them, while providing different .eslintrc files.

P.S. There's a jest environment coming in the next release of ESLint, it will register all of the necessary globals.

You are probably not assigning it after doing the replacement or replacing the wrong thing. Try :

That may depend on your web host if you are not hosting your own content. If your web host supports creating chron jobs, they may have a form for you to fill out that lets you select the frequency and input the absolute path to the file to execute. For instance, my web host (DreamHost) allows me to create custom cron jobs by typing in the absolute path to the file and selecting the frequency from a select menu. This may not be possible for your server, in which case you need to either edit the crontab directly or through your host specific method.

As Alister Bulman details above, create a PHP file to run using CLI (making sure to include #!/usr/bin/env php at the very start of the file before the <?php tag. This ensures that the shell knows which executable should be invoked when running the script.

You could add the path via your pythonrc file, which defaults to ~/.pythonrc on linux. ie.

import sys
sys.path.append('/path/to/dir')

You could also set the PYTHONPATH environment variable, in a global rc file, such ~/.profile on mac or linux, or via Control Panel -> System -> Advanced tab -> Environment Variables on windows.

I looked around for a solution to this for a while. It appears that the JDK doesn't have the Mozilla plugins (which is what Chrome uses) in it's installation. It is only in the JRE installation. There are a couple of DLLs that make up the plugin and they all start with np*

It looks like this function I found at weeknumber.net is pretty accurate and easy to use.

// This script is released to the public domain and may be used, modified and
// distributed without restrictions. Attribution not necessary but appreciated.
// Source: http://weeknumber.net/how-to/javascript 

// Returns the ISO week of the date.
Date.prototype.getWeek = function() {
  var date = new Date(this.getTime());
  date.setHours(0, 0, 0, 0);
  // Thursday in current week decides the year.
  date.setDate(date.getDate() + 3 - (date.getDay() + 6) % 7);
  // January 4 is always in week 1.
  var week1 = new Date(date.getFullYear(), 0, 4);
  // Adjust to Thursday in week 1 and count number of weeks from date to week1.
  return 1 + Math.round(((date.getTime() - week1.getTime()) / 86400000 - 3 + (week1.getDay() + 6) % 7) / 7);
}

If you're lucky like me and need to find the week number of the month a little adjust will do it:

// Returns the week in the month of the date.
Date.prototype.getWeekOfMonth = function() {
  var date = new Date(this.getTime());
  date.setHours(0, 0, 0, 0);
  // Thursday in current week decides the year.
  date.setDate(date.getDate() + 3 - (date.getDay() + 6) % 7);
  // January 4 is always in week 1.
  var week1 = new Date(date.getFullYear(), date.getMonth(), 4);
  // Adjust to Thursday in week 1 and count number of weeks from date to week1.
  return 1 + Math.round(((date.getTime() - week1.getTime()) / 86400000 - 3 + (week1.getDay() + 6) % 7) / 7);
}

SHA1 is a one way hash. So you can not really revert it.

That's why applications use it to store the hash of the password and not the password itself.

Like every hash function SHA-1 maps a large input set (the keys) to a smaller target set (the hash values). Thus collisions can occur. This means that two values of the input set map to the same hash value.

Obviously the collision probability increases when the target set is getting smaller. But vice versa this also means that the collision probability decreases when the target set is getting larger and SHA-1's target set is 160 bit.

Jeff Preshing, wrote a very good blog about Hash Collision Probabilities that can help you to decide which hash algorithm to use. Thanks Jeff.

In his blog he shows a table that tells us the probability of collisions for a given input set.

As you can see the probability of a 32-bit hash is 1 in 2 if you have 77163 input values.

A simple java program will show us what his table shows:

public class Main {

    public static void main(String[] args) {
        char[] inputValue = new char[10];

        Map<Integer, String> hashValues = new HashMap<Integer, String>();

        int collisionCount = 0;

        for (int i = 0; i < 77163; i++) {
            String asString = nextValue(inputValue);
            int hashCode = asString.hashCode();
            String collisionString = hashValues.put(hashCode, asString);
            if (collisionString != null) {
                collisionCount++;
                System.out.println("Collision: " + asString + " <-> " + collisionString);
            }
        }

        System.out.println("Collision count: " + collisionCount);
    }

    private static String nextValue(char[] inputValue) {
        nextValue(inputValue, 0);

        int endIndex = 0;
        for (int i = 0; i < inputValue.length; i++) {
            if (inputValue[i] == 0) {
                endIndex = i;
                break;
            }
        }

        return new String(inputValue, 0, endIndex);
    }

    private static void nextValue(char[] inputValue, int index) {
        boolean increaseNextIndex = inputValue[index] == 'z';

        if (inputValue[index] == 0 || increaseNextIndex) {
            inputValue[index] = 'A';
        } else {
            inputValue[index] += 1;
        }

        if (increaseNextIndex) {
            nextValue(inputValue, index + 1);
        }

    }

}

My output end with:

Collision: RvV <-> SWV
Collision: SvV <-> TWV
Collision: TvV <-> UWV
Collision: UvV <-> VWV
Collision: VvV <-> WWV
Collision: WvV <-> XWV
Collision count: 35135

It produced 35135 collsions and that's the nearly the half of 77163. And if I ran the program with 30084 input values the collision count is 13606. This is not exactly 1 in 10, but it is only a probability and the example program is not perfect, because it only uses the ascii chars between A and z.

Let's take the last reported collision and check

System.out.println("VvV".hashCode());
System.out.println("WWV".hashCode());

My output is

86390
86390

Conclusion:

If you have a SHA-1 value and you want to get the input value back you can try a brute force attack. This means that you have to generate all possible input values, hash them and compare them with the SHA-1 you have. But that will consume a lot of time and computing power. Some people created so called rainbow tables for some input sets. But these do only exist for some small input sets.

And remember that many input values map to a single target hash value. So even if you would know all mappings (which is impossible, because the input set is unbounded) you still can't say which input value it was.

On Linux and macOS you can run simple command to the shell:

subprocess.run('rm /tmp/*.bak', shell=True)

Just look in the ssl_engine.log in your Apache log directory where you should find something like:

[ssl:info] [pid 5963:tid 139718276048640] AH01876: mod_ssl/2.4.9 compiled against Server: Apache/2.4.9, Library: OpenSSL/1.0.1h

For the record, the file Microsoft.Cpp.Default.props can modify the env var VCTargetsPath and make subsequent usages of that var incorrect. I had that problem and solved it by setting VCTargetsPath10 and VCTargetsPath11 to the same value than VCTargetsPath.

This should be adapted according to the VS version you are using.

Here's a version for knockout.js based on the accepted answer:

Important: It does actually require jQuery too for the replacing, but I thought it may be useful to some.

ko.bindingHandlers.svgConvert =
    {
        'init': function ()
        {
            return { 'controlsDescendantBindings': true };
        },

        'update': function (element, valueAccessor, allBindings, viewModel, bindingContext)
        {
            var $img = $(element);
            var imgID = $img.attr('id');
            var imgClass = $img.attr('class');
            var imgURL = $img.attr('src');

            $.get(imgURL, function (data)
            {
                // Get the SVG tag, ignore the rest
                var $svg = $(data).find('svg');

                // Add replaced image's ID to the new SVG
                if (typeof imgID !== 'undefined')
                {
                    $svg = $svg.attr('id', imgID);
                }
                // Add replaced image's classes to the new SVG
                if (typeof imgClass !== 'undefined')
                {
                    $svg = $svg.attr('class', imgClass + ' replaced-svg');
                }

                // Remove any invalid XML tags as per http://validator.w3.org
                $svg = $svg.removeAttr('xmlns:a');

                // Replace image with new SVG
                $img.replaceWith($svg);

            }, 'xml');

        }
    };

Then just apply data-bind="svgConvert: true" to your img tag.

This solution completely replaces the img tag with a SVG and any additional bindings would not be respected.

I'm using zip.js and it seems to be quite useful. It's worth a look!

Check the Unzip demo, for example.

You could use groupby to split the DataFrame into subgroups according to the color:

for key, grp in df.groupby(['color']):

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

df = pd.read_table('data', sep='\s+')
fig, ax = plt.subplots()

for key, grp in df.groupby(['color']):
    ax = grp.plot(ax=ax, kind='line', x='x', y='y', c=key, label=key)

plt.legend(loc='best')
plt.show()

yields

As mentioned by others Android Toasts can either be LENGTH_LONG or LENGTH_SHORT. There is no way around this, nor should you follow any of the 'hacks' posted.

The purpose of Toasts are to display "non-essential" information and due to their lingering effect, messages may be put far out of context if their duration exceeds a certain threshold. If stock Toasts were modified so that they can display longer than LENGTH_LONG the message would linger on the screen until the application's process is terminated as toast views are added to the WindowManager and not a ViewGroup in your app. I would assume this is why it is hard coded.

If you absolutely need to show a toast style message longer than three and a half seconds I recommend building a view that gets attached to the Activity's content, that way it will disappear when the user exits the application. My SuperToasts library deals with this issue and many others, feel free to use it! You would most likely be interested in using SuperActivityToasts

I know that this is supper old but, after reading this whole page none of the solutions was working for me, although I didn't try Muhammad Rehan as the code was a little hard to follow, although I guess he was on the right track. When I say it didn't work that's not entirely true, sometimes it would work fine, I guess it is something to do with the length of the output before an EOF mark.

Anyway, the solution that worked for me was to use different threads to read the StandardOutput and StandardError and write the messages.

        StreamWriter sw = null;
        var queue = new ConcurrentQueue<string>();

        var flushTask = new System.Timers.Timer(50);
        flushTask.Elapsed += (s, e) =>
        {
            while (!queue.IsEmpty)
            {
                string line = null;
                if (queue.TryDequeue(out line))
                    sw.WriteLine(line);
            }
            sw.FlushAsync();
        };
        flushTask.Start();

        using (var process = new Process())
        {
            try
            {
                process.StartInfo.FileName = @"...";
                process.StartInfo.Arguments = $"...";
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.RedirectStandardOutput = true;
                process.StartInfo.RedirectStandardError = true;

                process.Start();

                var outputRead = Task.Run(() =>
                {
                    while (!process.StandardOutput.EndOfStream)
                    {
                        queue.Enqueue(process.StandardOutput.ReadLine());
                    }
                });

                var errorRead = Task.Run(() =>
                {
                    while (!process.StandardError.EndOfStream)
                    {
                        queue.Enqueue(process.StandardError.ReadLine());
                    }
                });

                var timeout = new TimeSpan(hours: 0, minutes: 10, seconds: 0);

                if (Task.WaitAll(new[] { outputRead, errorRead }, timeout) &&
                    process.WaitForExit((int)timeout.TotalMilliseconds))
                {
                    if (process.ExitCode != 0)
                    {
                        throw new Exception($"Failed run... blah blah");
                    }
                }
                else
                {
                    throw new Exception($"process timed out after waiting {timeout}");
                }
            }
            catch (Exception e)
            {
                throw new Exception($"Failed to succesfully run the process.....", e);
            }
        }
    }

Hope this helps someone, who thought this could be so hard!

I believe java gleans this from the environment variables in which it was launched, so you'll need to make sure your LANG and LC_* environment variables are set appropriately.

The locale manpage has full info on said environment variables.

Do this:

sudo rm /var/lib/mongodb/mongod.lock
sudo service mongod restart

If you are on Ubuntu 16.04 which you can figure out by runnign this:

lsb_release -a

You need to Create a new file at /lib/systemd/system/mongod.service with the following contents:

When I create an executable jar with dependencies (using this guide), all properties files are packaged into that jar too. How to stop it from happening? Thanks.

Properties files from where? Your main jar? Dependencies?

In the former case, putting resources under src/test/resources as suggested is probably the most straight forward and simplest option.

In the later case, you'll have to create a custom assembly descriptor with special excludes/exclude in the unpackOptions.

For socket.io version 1.4.5:

On server:

socket.on('end', function (){
    socket.disconnect(0);
});

On client:

var io = io();
io.emit('end');

You can do that using Python 2.

1. Remove request
2. Make that line: from urllib2 import urlopen

You cannot have request in Python 2, you need to have Python 3 or above.

ng v

Simply run the command above in terminal.

To add to Xavi's answer, Paul Irish's github David Desandro's gitgub offers a function called imagesLoaded() that works on the same principles, and gets around the problem of some browser's cached images not firing the .load() event (with clever original_src -> data_uri -> original_src switching).

It's is widely used and updated regularly, which contributes to it being the most robust solution to the problem, IMO.

Had to debug a site for native Android browser and came here. So I tried weinre on an OS X 10.9 (as weinre server) with Firefox 30.0 (weinre client) and an Android 4.1.2 (target). I'm really, really surprised of the result.

1. Download and install node runtime from http://nodejs.org/download/
2. Install weinre: sudo npm -g install weinre
3. Find out your current IP address at Settings > Network
4. Setup a weinre server on your machine: weinre --boundHost YOUR.IP.ADDRESS.HERE
5. In your browser call: http://YOUR.IP.ADRESS.HERE:8080
6. You'll see a script snippet, place it into your site: <script src="http://YOUR.IP.ADDRESS.HERE:8080/target/target-script-min.js"></script>
7. Open the debug client in your local browser: http://YOUR.IP.ADDRESS.HERE:8080/client
8. Finally on your Android: call the site you want to inspect (the one with the script inside) and see how it appears as "Target" in your local browser. Now you can open "Elements" or whatever you want.

Maybe 8080 isn't your default port. Then in step 4 you have to call weinre --httpPort YOURPORT --boundHost YOUR.IP.ADRESS.HERE.

And I don't remember exactly when it was, maybe somewhere after step 5, I had to accept incoming connections prompt, of course.

Happy debugging

P.S. I'm still overwhelmed how good that works. Even elements-highlighting work

Maybe your changes are not lost. Check "git reflog"

I quote the article below:

"Basically every action you perform inside of Git where data is stored, you can find it inside of the reflog. Git tries really hard not to lose your data, so if for some reason you think it has, chances are you can dig it out using git reflog"

See details:

http://gitready.com/intermediate/2009/02/09/reflog-your-safety-net.html

You can access data attributes something like this

event.target.dataset.tag

>>> x = 2.51
>>> x*100
250.99999999999997

the floating point numbers are inaccurate. in this case, it is 250.99999999999999, which is really close to 251, but int() truncates the decimal part, in this case 250.

you should take a look at the Decimal module or maybe if you have to do a lot of calculation at the mpmath library http://code.google.com/p/mpmath/ :),

img = cv2.imread('2015-05-27-191152.jpg',0)

The above line of code reads your image in grayscale color model, because of the 0 appended at the end. And if you again try to convert an already gray image to gray image it will show that error.

So either use above style or try undermentioned code:

img = cv2.imread('2015-05-27-191152.jpg')
gray_img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

You can also use DBMS_METADATA:

select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY', 'PADCAMPAIGN') 
from dual

FOR XLSX USE

SET IN $xlsName name from XLSX with extension. Example: $xlsName = 'teste.xlsx';

$objPHPExcel = new PHPExcel();

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$xlsName.'"');
header('Cache-Control: max-age=0');
$objWriter->save('php://output');

FOR XLS USE

SET IN $xlsName name from XLS with extension. Example: $xlsName = 'teste.xls';

$objPHPExcel = new PHPExcel();

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$xlsName.'"');
header('Cache-Control: max-age=0');
$objWriter->save('php://output');

interface AccountSelectParams {
  ...
}
const params = { ... };

const tmpParams: { [key in keyof AccountSelectParams]: any } | undefined = {};
  for (const key of Object.keys(params)) {
    const customKey = (key as keyof typeof params);
    if (key in params && params[customKey] && !this.state[customKey]) {
      tmpParams[customKey] = params[customKey];
    }
  }

please commented if you get the idea of this concept

Just use novalidate in your form.

<form name="myForm" role="form" novalidate class="form-horizontal" ng-hide="formMain">

Cheers!!!

Of course you can.

Your HTML there is just fine. To style the elements with css you can use the following approaches:

#y {
    ...
}

.x {
    ...
}

#y.x {
    ...
}

Also you can add as many classes as you wish to your element

<div id="id" class="classA classB classC ...">
</div>

And you can style that element using a selector with any combination of the classes and id. For example:

#id.classA.classB.classC {
     ...
}

#id.classC {
}

PhpEd is really good. You can step into/over/out of functions. You can run ad-hoc code, inspect variables, change variables. It is amazing.

Or you just put the variable in parenthesis

DECLARE @top INT = 10;

SELECT TOP (@Top) *
FROM <table_name>;

I created small tool called luster for downloading list of "likers" and "followers" of your Facebook page.

After download and unpack archive for your platform you can run it from terminal as

luster fans my-page-name

Where my-page-name is string identifier of your Facebook page.

You will be asked for email and password to your Facebook account. Note that this account need to have one of available page roles. Even Analyst is enough.

After while you should receive output similar to following

TIME,KIND,ID,NAME,LINK
1581665652,Like,111111111,John Doe,https://www.facebook.com/111111111
1581663355,Like,222222222,Kal Peterson,https://www.facebook.com/222222222
1581661970,Follow,333333333,Nikol Kus,https://www.facebook.com/333333333

This tool is based on reading table which can be found in Settings -> People and Other Pages section of your Facebook page.

Be aware that there is some limit up to 7k results from Facebook side. I tested it on two pages with more than 20k of fans and didn't get more then 7k results.

See https://github.com/zladovan/luster for details.

This for-loop will list all files in a directory.

pushd somedir
for /f "delims=" %%f in ('dir /b /a-d-h-s') do echo %%f
popd

"delims=" is useful to show long filenames with spaces in it....

'/b" show only names, not size dates etc..

Some things to know about dir's /a argument.

• Any use of "/a" would list everything, including hidden and system attributes.
• "/ad" would only show subdirectories, including hidden and system ones.
• "/a-d" argument eliminates content with 'D'irectory attribute.
• "/a-d-h-s" will show everything, but entries with 'D'irectory, 'H'idden 'S'ystem attribute.

If you use this on the commandline, remove a "%".

Hope this helps.

You can write the where clause as:

where (case when (:stateCode = '') then (1)
            when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
            else 0)
       end) = 1;

Alternatively, remove the case entirely:

where (:stateCode = '') or
      ((:stateCode != '') and vw.state_cd in (:stateCode));

Or, even better:

where (:stateCode = '') or vw.state_cd in (:stateCode)

In modern browsers (IE9+, FF4+, Chrome5+, Opera12+, Safari5+) you can use the built in Object.keys method:

var keys = Object.keys(myObject);

The above has a full polyfill but a simplified version is:

var getKeys = function(obj){
   var keys = [];
   for(var key in obj){
      keys.push(key);
   }
   return keys;
}

Alternatively replace var getKeys with Object.prototype.keys to allow you to call .keys() on any object. Extending the prototype has some side effects and I wouldn't recommend doing it.

Quoting when setting $FOO is not enough. You need to quote the variable reference as well:

me$ FOO="BAR * BAR"
me$ echo "$FOO"
BAR * BAR

You're confusing loading a module into the current interpreter process and calling a Python script externally.

The former can be done by importing the file you're interested in. execfile is similar to importing but it simply evaluates the file rather than creates a module out of it. Similar to "sourcing" in a shell script.

The latter can be done using the subprocess module. You spawn off another instance of the interpreter and pass whatever parameters you want to that. This is similar to shelling out in a shell script using backticks.

I've recently ren into this issue with Commodo cert I bought on ssls.com and I've had 3 files:

domain-name.ca-bundle domain-name.crt and domain-name.p7b

I've had to set it up on Nginx and this is the command I ran:

cat domain-name.ca-bundle domain-name.crt > commodo-ssl-bundle.crt

I then used commodo-ssl-bundle.crt inside the Nginx config file and works like a charm.

ORA-06512 is part of the error stack. It gives us the line number where the exception occurred, but not the cause of the exception. That is usually indicated in the rest of the stack (which you have still not posted).

In a comment you said

"still, the error comes when pNum is not between 12 and 14; when pNum is between 12 and 14 it does not fail"

Well, your code does this:

IF ((pNum < 12) OR (pNum > 14)) THEN     
    RAISE vSOME_EX;

That is, it raises an exception when pNum is not between 12 and 14. So does the rest of the error stack include this line?

ORA-06510: PL/SQL: unhandled user-defined exception

If so, all you need to do is add an exception block to handle the error. Perhaps:

PROCEDURE PX(pNum INT,pIdM INT,pCv VARCHAR2,pSup FLOAT)
AS
    vSOME_EX EXCEPTION;

BEGIN 
    IF ((pNum < 12) OR (pNum > 14)) THEN     
        RAISE vSOME_EX;
    ELSE  
        EXECUTE IMMEDIATE  'INSERT INTO M'||pNum||'GR (CV, SUP, IDM'||pNum||') VALUES('||pCv||', '||pSup||', '||pIdM||')';
    END IF;
exception
    when vsome_ex then
         raise_application_error(-20000
                                 , 'This is not a valid table:  M'||pNum||'GR');

END PX;

The documentation covers handling PL/SQL exceptions in depth.

• Find out more.

dynamic_cast should be what you are looking for.

EDIT:

DerivedType m_derivedType = m_baseType; // gives same error

The above appears to be trying to invoke the assignment operator, which is probably not defined on type DerivedType and accepting a type of BaseType.

DerivedType * m_derivedType = (DerivedType*) & m_baseType; // gives same error

You are on the right path here but the usage of the dynamic_cast will attempt to safely cast to the supplied type and if it fails, a NULL will be returned.

Going on memory here, try this (but note the cast will return NULL as you are casting from a base type to a derived type):

DerivedType * m_derivedType = dynamic_cast<DerivedType*>(&m_baseType);

If m_baseType was a pointer and actually pointed to a type of DerivedType, then the dynamic_cast should work.

Hope this helps!

function GetDateAndTime(dt) {

Making methods synchronized has two effects:

First, it is not possible for two invocations of synchronized methods on the same object to interleave. When one thread is executing a synchronized method for an object, all other threads that invoke synchronized methods for the same object block (suspend execution) until the first thread is done with the object.

Second, when a synchronized method exits, it automatically establishes a happens-before relationship with any subsequent invocation of a synchronized method for the same object. This guarantees that changes to the state of the object are visible to all threads

Have a look at this documentation page to understand intrinsic locks and lock behavior.

This will answer your question: On same object x , you can't call x.addA() and x.addB() at same time when one of the synchronized methods execution is in progress.

DialogFragment is basically a Fragment that can be used as a dialog.

Using DialogFragment over Dialog due to the following reasons:

• DialogFragment is automatically re-created after configuration changes and save & restore flow
• DialogFragment inherits full Fragment’s lifecycle
• No more IllegalStateExceptions and leaked window crashes. This was pretty common when the activity was destroyed with the Alert Dialog still there.

Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.

Converting a structure to JSON is very straightforward:

use strict;
use warnings;
use JSON::Any;

my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);

Consider both at the same time:

• having singleton objects as static instances inside the classes.
• having a common class (Context) that returns the singleton instances for all the singelton objects in your application, which has the advantage that the method names in Context will be meaningful for example: context.getLoggedinUser() instead of User.getInstance().

Furthermore, I suggest that you expand your Context to include not only access to singleton objects but some functionalities that need to be accessed globally, like for example: context.logOffUser(), context.readSavedData(), etc. Probably renaming the Context to Facade would make sense then.

For your use case, you may want to try using the fetch module to copy the public key from the server to your local machine. That way, it will only show a "changed" status when the file changes.

Switching to another branch in git. Straightforward answer,

git-checkout - Switch branches or restore working tree files

git fetch origin         <----this will fetch the branch
git checkout branch_name <--- Switching the branch

Before switching the branch make sure you don't have any modified files, in that case, you can commit the changes or you can stash it.

Packets and Frames are the names given to Protocol data units (PDUs) at different network layers

• Segments/Datagrams are units of data in the Transport Layer.

  In the case of the internet, the term Segment typically refers to TCP, while Datagram typically refers to UDP. However Datagram can also be used in a more general sense and refer to other layers (link):

  Datagram

  A self-contained, independent entity of data carrying sufficient information to be routed from the source to the destination computer without reliance on earlier exchanges between this source and destination computer andthe transporting network.

• Packets are units of data in the Network Layer (IP in case of the Internet)

• Frames are units of data in the Link Layer (e.g. Wifi, Bluetooth, Ethernet, etc).

The error was due to the way that I configured the Application Pool in IIS.

My web service uses an Application Tool configured for v2.0.50727. This resulted in the error message.

When I changed it to v4.0.30319, I did not get the error.

Also worth mentioning are

1. HPCToolkit (http://hpctoolkit.org/) - Open-source, works for parallel programs and has a GUI with which to look at the results multiple ways
2. Intel VTune (https://software.intel.com/en-us/vtune) - If you have intel compilers this is very good
3. TAU (http://www.cs.uoregon.edu/research/tau/home.php)

I have used HPCToolkit and VTune and they are very effective at finding the long pole in the tent and do not need your code to be recompiled (except that you have to use -g -O or RelWithDebInfo type build in CMake to get meaningful output). I have heard TAU is similar in capabilities.

Here's a workaround for Binding Columns in the DataGrid. Since the Columns property is ReadOnly, like everyone noticed, I made an Attached Property called BindableColumns which updates the Columns in the DataGrid everytime the collection changes through the CollectionChanged event.

If we have this Collection of DataGridColumn's

public ObservableCollection<DataGridColumn> ColumnCollection
{
    get;
    private set;
}

Then we can bind BindableColumns to the ColumnCollection like this

<DataGrid Name="dataGrid"
          local:DataGridColumnsBehavior.BindableColumns="{Binding ColumnCollection}"
          AutoGenerateColumns="False"
          ...>

The Attached Property BindableColumns

public class DataGridColumnsBehavior
{
    public static readonly DependencyProperty BindableColumnsProperty =
        DependencyProperty.RegisterAttached("BindableColumns",
                                            typeof(ObservableCollection<DataGridColumn>),
                                            typeof(DataGridColumnsBehavior),
                                            new UIPropertyMetadata(null, BindableColumnsPropertyChanged));
    private static void BindableColumnsPropertyChanged(DependencyObject source, DependencyPropertyChangedEventArgs e)
    {
        DataGrid dataGrid = source as DataGrid;
        ObservableCollection<DataGridColumn> columns = e.NewValue as ObservableCollection<DataGridColumn>;
        dataGrid.Columns.Clear();
        if (columns == null)
        {
            return;
        }
        foreach (DataGridColumn column in columns)
        {
            dataGrid.Columns.Add(column);
        }
        columns.CollectionChanged += (sender, e2) =>
        {
            NotifyCollectionChangedEventArgs ne = e2 as NotifyCollectionChangedEventArgs;
            if (ne.Action == NotifyCollectionChangedAction.Reset)
            {
                dataGrid.Columns.Clear();
                foreach (DataGridColumn column in ne.NewItems)
                {
                    dataGrid.Columns.Add(column);

            {
                dataGrid.Columns.Move(ne.OldStartingIndex, ne.NewStartingIndex);
            }

Before

return $_config[0] =& $config; 

After

$_config[0] =& $config;
return $_config[0]; 

Update

Added by NikiC

In PHP assignment expressions always return the assigned value. So $_config[0] =& $config returns $config - but not the variable itself, but a copy of its value. And returning a reference to a temporary value wouldn't be particularly useful (changing it wouldn't do anything).

Update

This fix has been merged into CI 2.2.1 (https://github.com/bcit-ci/CodeIgniter/commit/69b02d0f0bc46e914bed1604cfbd9bf74286b2e3). It's better to upgrade rather than modifying core framework files.

http://blarnee.com/wp/jquery-colour-selector-plug-in-with-support-for-graceful-degradation/

I think this is all you really need to do:

var listB = new List<int>{3, 4, 5};
var listA = new List<int>{1, 2, 3, 4, 5};

var listMerged = listA.Union(listB);

Extending a big abstract class regarding data access logic ,

After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.

It's incorrect to use zeros in date or in datetime, just put null instead of zeros.

The answer to "Given a class, see if instance has method (Ruby)" is better. Apparently Ruby has this built-in, and I somehow missed it. My answer is left for reference, regardless.

Ruby classes respond to the methods instance_methods and public_instance_methods. In Ruby 1.8, the first lists all instance method names in an array of strings, and the second restricts it to public methods. The second behavior is what you'd most likely want, since respond_to? restricts itself to public methods by default, as well.

Foo.public_instance_methods.include?('bar')

In Ruby 1.9, though, those methods return arrays of symbols.

Foo.public_instance_methods.include?(:bar)

If you're planning on doing this often, you might want to extend Module to include a shortcut method. (It may seem odd to assign this to Module instead of Class, but since that's where the instance_methods methods live, it's best to keep in line with that pattern.)

class Module
  def instance_respond_to?(method_name)
    public_instance_methods.include?(method_name)
  end
end

If you want to support both Ruby 1.8 and Ruby 1.9, that would be a convenient place to add the logic to search for both strings and symbols, as well.

If you have installed Anaconda but are not able to load the correct versions of python and ipython, or if you see conda: command not found when trying to use conda, this may be an issue with your PATH environment variable. At the prompt, type:

export PATH=~/anaconda/bin:$PATH

For this example, it is assumed that Anaconda is installed in the default ~/anaconda location.

Two more uses not mentioned in other answers:

Logging

Take this example script:

set -x
: Logging message here
example_command

The first line, set -x, makes the shell print out the command before running it. It's quite a useful construct. The downside is that the usual echo Log message type of statement now prints the message twice. The colon method gets round that. Note that you'll still have to escape special characters just like you would for echo.

Cron job titles

I've seen it being used in cron jobs, like this:

45 10 * * * : Backup for database ; /opt/backup.sh

This is a cron job that runs the script /opt/backup.sh every day at 10:45. The advantage of this technique is that it makes for better looking email subjects when the /opt/backup.sh prints some output.

Note, the batch file approaches will be limited to the line limit for the DOS command processor - see What is the command line length limit?.

So if trying to process a file that has any lines more that 8192 characters the script will just skip them as the value can't be held.

I found the error because i was new to git you must check whether you have entered the correct syntax

PHP's strlen() function returns the number of ASCII characters.

strlen('borsc') -> 5 (bytes)

strlen('boršc') -> 7 (bytes)

$limit_in_kBytes = 20000;

$pointer = 0;
while(strlen($your_string) > (($pointer + 1) * $limit_in_kBytes)){
    $str_to_handle = substr($your_string, ($pointer * $limit_in_kBytes ), $limit_in_kBytes);
    // here you can handle (0 - n) parts of string
    $pointer++;
}

$str_to_handle = substr($your_string, ($pointer * $limit_in_kBytes), $limit_in_kBytes);
// here you can handle last part of string

.. or you can use a function like this:

function parseStrToArr($string, $limit_in_kBytes){
    $ret = array();

    $pointer = 0;
    while(strlen($string) > (($pointer + 1) * $limit_in_kBytes)){
        $ret[] = substr($string, ($pointer * $limit_in_kBytes ), $limit_in_kBytes);
        $pointer++;
    }

    $ret[] = substr($string, ($pointer * $limit_in_kBytes), $limit_in_kBytes);

    return $ret;
}

$arr = parseStrToArr($your_string, $limit_in_kBytes = 20000);

Let me list a use case below. Hope it helps. Here I'm trying to find the Table Owner of the Table 'Stud_dtls' from the DB 'Students'. As Mikael mentioned, sysname could be used when there is a need for creating some dynamic sql which needs variables holding table names, column names and server names. Just thought of providing a simple example to supplement his point.

USE Students

DECLARE @TABLE_NAME sysname

SELECT @TABLE_NAME = 'Stud_dtls'

SELECT TABLE_SCHEMA 
  FROM INFORMATION_SCHEMA.Tables
 WHERE TABLE_NAME = @TABLE_NAME

I found work around from this post https://jira.spring.io/browse/SPR-8263.

Based on this post you can return a typed list like this:

ResponseEntity<? extends ArrayList<User>> responseEntity = restTemplate.getForEntity(restEndPointUrl, (Class<? extends ArrayList<User>>)ArrayList.class, userId);

This should work:

GetCountries():Observable<CountryData[]>  {
  return this.http.get(`http://services.groupkt.com/country/get/all`)
    .map((res:Response) => <CountryData[]>res.json());
}

For this to work you will need to import the following:

import 'rxjs/add/operator/map'

Why are you wrapping the $_POST array in an array?

You can access your "id" and "value" arrays using the following

// assuming the appropriate isset() checks for $_POST['id'] and $_POST['value']

$ids = $_POST['id'];
$values = $_POST['value'];

foreach ($ids as $idx => $id) {
    // ...
}

foreach ($values as $idx => $value) {
    // ...
}

I have had trouble myself displaying Snackbar until now. Here is the simplest way to display a Snackbar. To display it as your Main Activity Starts, just put these two lines inside your OnCreate()

    Snackbar snackbar = Snackbar.make(findViewById(android.R.id.content), "Welcome To Main Activity", Snackbar.LENGTH_LONG);
    snackbar.show();

P.S. Just make sure you have imported the Android Design Support.(As mentioned in the question).

For Kotlin,

Snackbar.make(findViewById(android.R.id.content), message, Snackbar.LENGTH_SHORT).show()

Ok First of all this is a very clear error message. Just look at this many devs miss this including my self. Have a look at the screen shot here please.

Under Products > Facebook Login > Settings

or just go to this url here (Replace YOUR_APP_ID with your app id lol):

https://developers.facebook.com/apps/YOUR_APP_ID/fb-login/settings/

If you are working on localhost:3000 Make sure you have https://localhost:3000/auth/facebook/callback

Ofcourse you don't have to have the status live (Green Switch on top right corner) but in my case, I am deploying to heroku now and will soon replace localhost:3000 with https://myapp.herokuapp.com/auth/facebook/callback

Of course I will update the urls in Settings/Basic & Settings/Advanced and also add a privacy policy url in the basic section.

I am assuming that you have properly configured initializers/devise.rb if you are using devise and you have the proper facebook gem 'omniauth-facebook', '~> 4.0' gem installed and gem 'omniauth', '~> 1.6', and you have the necessary columns in your users table such as uid, image, and provider. That's it.

hash.each do |key, array|
  puts "#{key}-----"
  puts array
end

Regarding order I should add, that in 1.8 the items will be iterated in random order (well, actually in an order defined by Fixnum's hashing function), while in 1.9 it will be iterated in the order of the literal.

If you get an exception for : Invalid column type

Please use getNamedParameterJdbcTemplate() instead of getJdbcTemplate()

 List<Foo> foo = getNamedParameterJdbcTemplate().query("SELECT * FROM foo WHERE a IN (:ids)",parameters,
 getRowMapper());

Note that the second two arguments are swapped around.

a csv-file is just like any other file a stream of characters. the getline reads from the file up to a delimiter however in your case the delimiter for the last item is not ' ' as you assume

getline(file, genero, ' ') ; 

it is newline \n

so change that line to

getline(file, genero); // \n is default delimiter

This is likely caused by your application's connection pool; not an Oracle DBMS issue. Most connection pools have a validate statement that can execute before giving you the connection. In oracle you would want "Select 1 from dual".

The reason it started occurring after you restarted the server is that the connection pool was probably added without a restart and you are just now experiencing the use of the connection pool for the first time. What is the modification dates on your resource files that deal with database connections?

Validate Query example:

 <Resource name="jdbc/EmployeeDB" auth="Container" 
            validationQuery="Select 1 from dual" type="javax.sql.DataSource" username="dbusername" password="dbpassword"
            driverClassName="org.hsql.jdbcDriver" url="jdbc:HypersonicSQL:database"
            maxActive="8" maxIdle="4"/>

EDIT: In the case of Grails, there are similar configuration options for the grails pool. Example for Grails 1.2 (see release notes for Grails 1.2)

dataSource {
    pooled = true
    dbCreate = "update"
    url = "jdbc:mysql://localhost/yourDB"
    driverClassName = "com.mysql.jdbc.Driver"
    username = "yourUser"
    password = "yourPassword"
    properties {
        maxActive = 50
        maxIdle = 25
        minIdle = 5
        initialSize = 5
        minEvictableIdleTimeMillis = 60000
        timeBetweenEvictionRunsMillis = 60000
        maxWait = 10000     
    }   
}

When I encountered this exception, there was an InnerException "Transaction Timeout". Since this was during a debug session, when I halted my code for some time inside the TransactionScope, I chose to ignore this issue.

When this specific exception with a timeout appears in deployed code, I think that the following section in you .config file will help you out:

<system.transactions> 
        <machineSettings maxTimeout="00:05:00" /> 
</system.transactions>

Redirect the output to a file like this:

./a.sh > somefile 2>&1 &

This will redirect both stdout and stderr to the same file. If you want to redirect stdout and stderr to two different files use this:

./a.sh > stdoutfile 2> stderrfile &

You can use /dev/null as one or both of the files if you don't care about the stdout and/or stderr.

See bash manpage for details about redirections.

Now, sometimes you already have less open, and you can't use cat on it. For example, you did a | less, and you can't just reopen a file, as that's actually a stream.

If all you need is to identify end of line, one easy way is to search for the last character on the line: /.$. The search will highlight the last character, even if it is a blank, making it easy to identify it.

That will only help with the end of line case. If you need other special characters, you can use the cat -vet solution above with marks and pipe:

• mark the top of the text you're interested in: ma
• go to the bottom of the text you're interested in and mark it, as well: mb
• go back to the mark a: 'a
• pipe from a to b through cat -vet and view the result in another less command: |bcat -vet | less

This will open another less process, which shows the result of running cat -vet on the text that lies between marks a and b.

If you want the whole thing, instead, do g|$cat -vet | less, to go to the first line and filter all lines through cat.

The advantage of this method over less options is that it does not mess with the output you see on the screen.

One would think that eight years after this question was originally posted, less would have that feature... But I can't even see a feature request for it on https://github.com/gwsw/less/issues

If you haven't already created the project in Github, do so on that site. If memory serves, they display a page that tells you exactly how to get your existing code into your new repository. At the risk of oversimplification, though, you'd follow Veeti's instructions, then:

git remote add [name to use for remote] [private URI] # associate your local repository to the remote
git push [name of remote] master # push your repository to the remote

As best I can tell, it is not possible to update the select2 options without refreshing the entire list or entering some search text and using a query function.

What are those buttons supposed to do? If they are used to determine the select options, why not put them outside of the select box, and have them programmatically set the select box data and then open it? I don't understand why you would want to put them on top of the search box. If the user is not supposed to search, you can use the minimumResultsForSearch option to hide the search feature.

Edit: How about this...

HTML:

<input type="hidden" id="select2" class="select" />

Javascript

var data = [{id: 0, text: "Zero"}],
    select = $('#select2');

select.select2({
  query: function(query) {
    query.callback({results: data});
  },
  width: '150px'
});

console.log('Opening select2...');
select.select2('open');

setTimeout(function() {
  console.log('Updating data...');
  data = [{id: 1, text: 'One'}];
}, 1500);

setTimeout(function() {
  console.log('Fake keyup-change...');
  select.data().select2.search.trigger('keyup-change');
}, 3000);

Example: Plunker

Edit 2: That will at least get it to update the list, however there is still some weirdness if you have entered search text before triggering the keyup-change event.

You can call the method getBoundingClientRect() on a reference to the element. Then you can examine the top, left, right and/or bottom properties...

var offsets = document.getElementById('11a').getBoundingClientRect();
var top = offsets.top;
var left = offsets.left;

If using jQuery, you can use the more succinct code...

var offsets = $('#11a').offset();
var top = offsets.top;
var left = offsets.left;

Most of the answers I have seen are objectively exploring possible issues with the environment, which is probably correct for 99% of the people running into this issue (unable to copy file from ... to ... access is denied).

I thought I should share my experience for the 1% who ran into this problem due to misc reasons.

I wrote a batch file renaming program that i use to act on tens of thousands of files, and my AntiVirus interpreted it as trojan and auto quarantined it. Having this path sit in my AntiVirus' blacklist, visual studio can never copy the *.exe into the bin folder, hence resulting unable to copy .exe.

My resolution is to whitelist this path and the issue is resolve.

Cheers.

A bit late answer, but I suggest you have a look at a not well known project on codeplex called ConferenceXP

ConferenceXP is an open source research platform that provides simple, flexible, and extensible conferencing and collaboration using high-bandwidth networks and the advanced multimedia capabilities of Microsoft Windows. ConferenceXP helps researchers and educators develop innovative applications and solutions that feature broadcast-quality audio and video in support of real-time distributed collaboration and distance learning environments.

Full source (it's huge!) is provided. It implements the RTP protocol.

You can also set onSubmit attribute's value in form tag. You can set its value using Javascript.

Something like this:

<form id="whatever" name="whatever" onSubmit="return xyz();">
    Here is your entire form
    <input type="submit">
</form>;

<script type=text/javascript>
function xyz() {
  document.getElementById('whatever').action = 'whatever you want'
}
</script>

Remember that onSubmit has higher priority than action attribute. So whenever you specify onSubmit value, that operation will be performed first and then the form will move to action.

If I am not mistaken, it will be onunload event.

"Occurs when the application is about to be unloaded." - MSDN

Use the P format string. This will vary by culture:

String.Format("Value: {0:P2}.", 0.8526) // formats as 85.26 % (varies by culture)

In your notification implementation, use a code like this:

NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
...
Intent intent = new Intent(this, ExampleActivity.class);
intent.putExtra("EXTRA_KEY", "value");

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
nBuilder.setContentIntent(pendingIntent);
...

To Get Intent extra values in the ExampleActivity, use the following code:

...
Intent intent = getIntent();
if(intent!=null) {
    String extraKey = intent.getStringExtra("EXTRA_KEY");
}
...

VERY IMPORTANT NOTE: the Intent::putExtra() method is an Overloaded one. To get the extra key, you need to use Intent::get[Type]Extra() method.

Note: NOTIFICATION_ID and NOTIFICATION_CHANNEL_ID are an constants declared in ExampleActivity

As stated in the answer by Henrik, titles are left-aligned by default starting with ggplot 2.2.0. Titles can be centered by adding this to the plot:

theme(plot.title = element_text(hjust = 0.5))

However, if you create many plots, it may be tedious to add this line everywhere. One could then also change the default behaviour of ggplot with

theme_update(plot.title = element_text(hjust = 0.5))

Once you have run this line, all plots created afterwards will use the theme setting plot.title = element_text(hjust = 0.5) as their default:

theme_update(plot.title = element_text(hjust = 0.5))
ggplot() + ggtitle("Default is now set to centered")

To get back to the original ggplot2 default settings you can either restart the R session or choose the default theme with

theme_set(theme_gray())

you can do it with pd.date_range() and Timestamp. Let's say you have read a csv file with a date column using parse_dates option:

df = pd.read_csv('my_file.csv', parse_dates=['my_date_col'])

Then you can define a date range index :

rge = pd.date_range(end='15/6/2020', periods=2)

and then filter your values by date thanks to a map:

df.loc[df['my_date_col'].map(lambda row: row.date() in rge)]

Here is an example:

Process.Start("CMD", "/C Pause")


/C  Carries out the command specified by string and then terminates
/K  Carries out the command specified by string but remains

And here is a extended function: (Notice the comment-lines using CMD commands.)

Use the BigInteger class that is a part of the Java library.

http://java.sun.com/j2se/1.5.0/docs/api/java/math/BigInteger.html

The issue you have encountered is that UDFs cannot modify the Excel environment, they can only return a value to the calling cell.

There are several alternatives

1. For the sample given you don't actually need VBA. This formula will work
   ='C:\Users\UserName\Desktop\[TestSample.xlsx]Sheet1'!$B$2

2. Use a rather messy work around: See this answer

3. You can use ExecuteExcel4Macro or OLEDB

You can use date to get time and date of a day:

[pengyu@GLaDOS ~]$date
Tue Aug 27 15:01:27 CST 2013

Also hwclock would do:

[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST  -0.516080 seconds

For customized output, you can either redirect the output of date to something like awk, or write your own program to do that.

Remember to put your own executable scripts/binary into your PATH (e.g. /usr/bin) to make it invokable anywhere.

Use case match for early return purpose. It will force you to declare all return branches explicitly, preventing the careless mistake of forgetting to write return somewhere.

neater:

function BlockID() {
  return {
    "s":"Images/Block_01.png",
    "g":"Images/Block_02.png",
    "C":"Images/Block_03.png",
    "d":"Images/Block_04.png"
   }
}

or just

var images = {
  "s":"Images/Block_01.png",
  "g":"Images/Block_02.png",
  "C":"Images/Block_03.png",
  "d":"Images/Block_04.png"
}

You can use do.call:

 do.call("<-",list(parameter_name, parameter_value))

What sort of button, neither a Forms Control nor an ActiveX control should affect the used range.

It is a known problem that excel does not keep track of the used range very well. Any reference to the used range via VBA will reset the value to the current used range. So try running this sub procedure:

Sub ResetUsedRng()
    Application.ActiveSheet.UsedRange 
End Sub 

Failing that you may well have some formatting hanging round. Try clearing/deleting all the cells after your last row.

Regarding the above also see:

Excel Developer Tip

Another method to find the last used cell:

    Dim rLastCell As Range

    Set rLastCell = ActiveSheet.Cells.Find(What:="*", After:=.Cells(1, 1), LookIn:=xlFormulas, LookAt:= _
    xlPart, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, MatchCase:=False)

Change the search direction to find the first used cell.

I've used another way for a few times. In fact, it is a manual git rebase -i and it is useful when you want to rearrange several commits including squashing or splitting some of them. The main advantage is that you don't have to decide about every commit's destiny at a single moment. You'll also have all Git features available during the process unlike during a rebase. For example, you can display the log of both original and rewritten history at any time, or even do another rebase!

I'll refer to the commits in the following way, so it's readable easily:

C # good commit after a bad one
B # bad commit
A # good commit before a bad one

Your history in the beginning looks like this:

x - A - B - C
|           |
|           master
|
origin/master

We'll recreate it to this way:

x - A - B*- C'
|           |
|           master
|
origin/master

Procedure

git checkout B       # get working-tree to the state of commit B
git reset --soft A   # tell Git that we are working before commit B
git checkout -b rewrite-history   # switch to a new branch for alternative history

Improve your old commit using git add (git add -i, git stash etc.) now. You can even split your old commit into two or more.

git commit           # recreate commit B (result = B*)
git cherry-pick C    # copy C to our new branch (result = C')

Intermediate result:

x - A - B - C 
|    \      |
|     \     master
|      \
|       B*- C'
|           |
|           rewrite-history
|
origin/master

Let's finish:

git checkout master
git reset --hard rewrite-history  # make this branch master

Or using just one command:

git branch -f master  # make this place the new tip of the master branch

That's it, you can push your progress now.

The last task is to delete the temporary branch:

git branch -d rewrite-history

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

let my_u8: u8 = "42".parse::<u8>().unwrap();
let my_u32: u32 = "42".parse::<u32>().unwrap();

// or, to be safe, match the `Err`
match "foobar".parse::<i32>() {
  Ok(n) => do_something_with(n),
  Err(e) => weep_and_moan(),
}

str::parse::<u32> returns a Result<u32, core::num::ParseIntError> and Result::unwrap "Unwraps a result, yielding the content of an Ok [or] panics if the value is an Err, with a panic message provided by the Err's value."

str::parse is a generic function, hence the type in angle brackets.

To convert you PHP array to JS , you can do it like this :

var js_array = [<?php echo '"'.implode('","',  $disabledDaysRange ).'"' ?>];

or using JSON_ENCODE :

var js_array =<?php echo json_encode($disabledDaysRange );?>;

Example without JSON_ENCODE:

<script type='text/javascript'>
    <?php
    $php_array = array('abc','def','ghi');
    ?>
    var js_array = [<?php echo '"'.implode('","', $php_array).'"' ?>];
    alert(js_array[0]);
</script>

Example with JSON_ENCODE :

<script type='text/javascript'>
    <?php
    $php_array = array('abc','def','ghi');
    ?>
    var js_array =<?php echo json_encode($disabledDaysRange );?>;
    alert(js_array[0]);
</script>

<script type="text/javascript">
      $(document).ready(function() {
                showWarning('@ViewBag.Message');
      });

</script>

You can use ViewBag.PropertyName in javascript like this.

I know this is old, but came across it looking for a simpler way, and this is how i do it, just create a new list of the same object and add it to the one you want to use e.g.

Subject[] subjectsList = {new Subject1{....}, new Subject2{....}, new Subject3{....}} 
univStudent.subjects = subjectsList ;

Do this

    <% for(int i = 0; i < allFestivals.size(); i+=1) { %>
        <tr>      
            <td><%=allFestivals.get(i).getFestivalName()%></td>
        </tr>
    <% } %>

Better way is to use c:foreach see link jstl for each

Here is an extension method that will convert an object to a ViewDataDictionary.

public static ViewDataDictionary ToViewDataDictionary(this object values)
{
    var dictionary = new ViewDataDictionary();
    foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(values))
    {
        dictionary.Add(property.Name, property.GetValue(values));
    }
    return dictionary;
}

You can then use it in your view like so:

@Html.Partial("_MyPartial", new
{
    Property1 = "Value1",
    Property2 = "Value2"
}.ToViewDataDictionary())

Which is much nicer than the new ViewDataDictionary { { "Property1", "Value1" } , { "Property2", "Value2" }} syntax.

Then in your partial view, you can use ViewBag to access the properties from a dynamic object rather than indexed properties, e.g.

<p>@ViewBag.Property1</p>
<p>@ViewBag.Property2</p>

The short answer is yes, as long as it is a public IP address.

Issuance of certificates to reserved IP addresses is not allowed, and all certificates previously issued to reserved IP addresses were revoked as of 1 October 2016.

According to the CA Browser forum, there may be compatibility issues with certificates for IP addresses unless the IP address is in both the commonName and subjectAltName fields. This is due to legacy SSL implementations which are not aligned with RFC 5280, notably, Windows OS prior to Windows 10.

Sources:

1. Guidance on IP Addresses In Certificates CA Browser Forum
2. Baseline Requirements 1.4.1 CA Browser Forum
3. The (soon to be) not-so Common Name unmitigatedrisk.com
4. RFC 5280 IETF

_{Note: an earlier version of this answer stated that all IP address certificates would be revoked on 1 October 2016. Thanks to Navin for pointing out the error.}

You can create your own method Equivalent to

String.IsNullOrWhiteSpace(value)

function IsNullOrWhiteSpace( value) {

    if (value== null) return true;

    return value.replace(/\s/g, '').length == 0;
}

In advance of my questions being answered, this is how I'd go about it:

Minimize the number of statements and the work they do issued in relative terms.

All scenarios assume you have a table of IDs (PURGE_IDS) to delete from TABLE_1, TABLE_2, etc.

Consider Using CREATE TABLE AS SELECT for really large deletes

If there's no concurrent activity, and you're deleting 30+ % of the rows in one or more of the tables, don't delete; perform a create table as select with the rows you wish to keep, and swap the new table out for the old table. INSERT /*+ APPEND */ ... NOLOGGING is surprisingly cheap if you can afford it. Even if you do have some concurrent activity, you may be able to use Online Table Redefinition to rebuild the table in-place.

Don't run DELETE statements you know won't delete any rows

If an ID value exists in at most one of the six tables, then keep track of which IDs you've deleted - and don't try to delete those IDs from any of the other tables.

CREATE TABLE TABLE1_PURGE NOLOGGING
AS 
SELECT ID FROM PURGE_IDS INNER JOIN TABLE_1 ON PURGE_IDS.ID = TABLE_1.ID;

DELETE FROM TABLE1 WHERE ID IN (SELECT ID FROM TABLE1_PURGE);

DELETE FROM PURGE_IDS WHERE ID IN (SELECT ID FROM TABLE1_PURGE);

DROP TABLE TABLE1_PURGE;

and repeat.

Manage Concurrency if you have to

Another way is to use PL/SQL looping over the tables, issuing a rowcount-limited delete statement. This is most likely appropriate if there's significant insert/update/delete concurrent load against the tables you're running the deletes against.

declare
  l_sql varchar2(4000);
begin
  for i in (select table_name from all_tables 
             where table_name in ('TABLE_1', 'TABLE_2', ...)
             order by table_name);
  loop
    l_sql := 'delete from ' || i.table_name || 
             ' where id in (select id from purge_ids) ' || 
             '   and rownum <= 1000000';
    loop
      commit;
      execute immediate l_sql;
      exit when sql%rowcount <> 1000000;  -- if we delete less than 1,000,000
    end loop;                             -- no more rows need to be deleted!
  end loop;
  commit;
end;

Immediately Invoked Async Arrow Function:

(async () => {
    console.log(await asyncFunction());
})();

Immediately Invoked Async Function Expression:

    console.log(await asyncFunction());
})();

System.setProperty("https.protocols", "TLSv1.2"); worked in my case. Have you checked that within the application?

The next approach work to me with Visual Studio 2013 Update 4 1- From Solution Explorer right click on References then select add references 2- Assemblies > Framework > System.Data.OracleClient > OK and after that you free to add using System.Data.OracleClient in your application and deal with database like you do with Sql Server database except changing the prefix from Sql to Oracle as in SqlCommand become OracleCommand for example to link to Oracle XE

OracleConnection oraConnection = new OracleConnection(@"Data Source=XE; User ID=system; Password=*myPass*");
public void Open()
{
if (oraConnection.State != ConnectionState.Open)
{
oraConnection.Open();
}
}
public void Close()
{
if (oraConnection.State == ConnectionState.Open)
{
oraConnection.Close();
}}

and to execute some command like INSERT, UPDATE, or DELETE using stored procedure we can use the following method

public void ExecuteCMD(string storedProcedure, OracleParameter[] param)
{
OracleCommand oraCmd = new OracleCommand();
oraCmd,CommandType = CommandType.StoredProcedure;
oraCmd.CommandText = storedProcedure;
oraCmd.Connection = oraConnection;

if(param!=null)
{
oraCmd.Parameters.AddRange(param);
}
try
{
oraCmd.ExecuteNoneQuery();
}
catch (Exception)
{
MessageBox.Show("Sorry We've got Unknown Error","Connection Error",MessageBoxButtons.OK,MessageBoxIcon.Error);
}
}

I know it's an old question, but for everyone on google ending up here looking for information on how to deal with blocking and non-blocking sockets here is an in depth explanation of the different ways how to deal with the I/O modes of sockets - http://dwise1.net/pgm/sockets/blocking.html.

Quick summary:

• So Why do Sockets Block?

• What are the Basic Programming Techniques for Dealing with Blocking Sockets?

  • Have a design that doesn't care about blocking
  • Using select
  • Using non-blocking sockets.
  • Using multithreading or multitasking

You can use both != or <>.

However, note that != is preferred where <> is deprecated.

I got this error when using the Atom editor and mingw (through a package called gpp-compiler) for C++. Closing the open console window fixed my issue.

Can you just do:

for key in mydict.keys():
    f.write(str(key) + ":" + str(mydict[key]) + ",");

So that you can have

key_1: value_1, key_2: value_2

button {
    background:transparent;
    border:none;
    outline:none;
    display:block;
    height:200px;
    width:200px;
    cursor:pointer;
}

Give the height and width with respect to the image in the background.This removes the borders and color of a button.You might also need to position it absolute so you can correctly place it where you need.I cant help you further without posting you code

To make it truly invisible you have to set outline:none; otherwise there would be a blue outline in some browsers and you have to set display:block if you need to click it and set dimensions to it

With Pure CSS it worked for me. Make it transparent when Entered/Focues in input

 input:focus::-webkit-input-placeholder { /* Chrome/Opera/Safari */
    color: transparent !important;
 }
 input:focus::-moz-placeholder { /* Firefox 19+ */
   color: transparent !important;
 }
 input:focus:-ms-input-placeholder { /* IE 10+ */
   color: transparent !important;
 }
 input:focus:-moz-placeholder { /* Firefox 18- */
   color: transparent !important;
  }

Too much code for this task, checkout this library https://github.com/kodart/Httpzoid Is uses GSON internally and provides API that works with objects. All JSON details are hidden.

Http http = HttpFactory.create(context);
http.get("http://example.com/users")
    .handler(new ResponseHandler<User[]>() {
        @Override
        public void success(User[] users, HttpResponse response) {
        }
    }).execute();

Try this

$_SERVER['HTTP_CF_CONNECTING_IP'];

instead of

$_SERVER["REMOTE_ADDR"];

This won't work for InnoDB. Use this workaround only if you are trying to copy MyISAM databases.

If locking the tables during backup, and, possibly, pausing MySQL during the database import is acceptable, mysqlhotcopy may work faster.

E.g.

Backup:

# mysqlhotcopy -u root -p password db_name /path/to/backup/directory

Restore:

cp /path/to/backup/directory/* /var/lib/mysql/db_name

mysqlhotcopy can also transfer files over SSH (scp), and, possibly, straight into the duplicate database directory.

E.g.

# mysqlhotcopy -u root -p password db_name /var/lib/mysql/duplicate_db_name

Firefox supports XHR download progress events.

The error message means that you need to invoke volteado and siprimo on an instance of the Program class. E.g.:

...
Program p = new Program();
long av = p.volteado(a); // av is "a" but swapped

if (p.siprimo(a) == false && p.siprimo(av) == false)
...

They cannot be invoked directly from the Main method because Main is static while volteado and siprimo are not.

The easiest way to fix this is to make the volteado and siprimo methods static:

private static bool siprimo(long a)
{
    ...
}

private static bool volteado(long a)
{
   ...
}

2. Copy/paste command bellow

sysctl -a | grep machdep.cpu.features

3. You may see output similar to:

Mac:~ user$ sysctl -a | grep machdep.cpu.features kern.exec: unknown type returned machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON VMX EST TM2 TPR PDCM

If you see VMX entry then CPU supports Intel VT-x feature, but it still may be disabled.

Collation can be simply thought of as sort order.

In English (and it's strange cousin, American), collation may be a pretty simple matter consisting of ordering by the ASCII code.

Once you get into those strange European languages with all their accents and other features, collation changes. For example, though the different accented forms of a may exist at disparate code points, they may all need to be sorted as if they were the same letter.

You simply call

Blog::all();

//example usage.
$posts = Blog::all();

$posts->each(function($post) // foreach($posts as $post) { }
{
    //do something
}

from anywhere in your application.

Reading the documentation will help a lot.

You can use gregexpr

 gregexpr(pattern ='2',"the2quickbrownfoxeswere2tired")


[[1]]
[1]  4 24
attr(,"match.length")
[1] 1 1
attr(,"useBytes")
[1] TRUE

or perhaps str_locate_all from package stringr which is a wrapper for gregexpr stringi::stri_locate_all (as of stringr version 1.0)

library(stringr)
str_locate_all(pattern ='2', "the2quickbrownfoxeswere2tired")

[[1]]
     start end
[1,]     4   4
[2,]    24  24

note that you could simply use stringi

library(stringi)
stri_locate_all(pattern = '2', "the2quickbrownfoxeswere2tired", fixed = TRUE)

Another option in base R would be something like

lapply(strsplit(x, ''), function(x) which(x == '2'))

should work (given a character vector x)

Response.write() don't give formatted output. The latter one allows you to write formatted output.

Response.write - it writes the text stream Response.output.write - it writes the HTTP Output Stream.

I had the same problem. Manually removing and adding the dlls did not help. ClassLibraries did not compile for all the projects and were missing in the ...\bin\Debug folder for the project [because I cleaned solution by mistake]. Since the class library did not compile that means there may be some errors somewhere in one of those sub projects.

Solution: Since my dlls were there for the ...\bin\Release folder, I tried to rebuild on Release mode and found an error on one line in one of the sub projects. Solving the error and rebuilding the solution got rid off the build error.

Coming to this late in the day but here is my pennyworth with an object that just happens to hold some useful paths in an app but you can adapt it for anything where you want a sorta dict of information that you can access with getattr and dot notation (which is what I think this question is really about):

import os

def x_path(path_name):
    return getattr(x_path, path_name)

x_path.root = '/home/x'
for name in ['repository', 'caches', 'projects']:
    setattr(x_path, name, os.path.join(x_path.root, name))

This is cool because now:

In [1]: x_path.projects
Out[1]: '/home/x/projects'

In [2]: x_path('caches')
Out[2]: '/home/x/caches'

So this uses the function object like the above answers but uses the function to get the values (you can still use (getattr, x_path, 'repository') rather than x_path('repository') if you prefer).

This worked for me!
Open build.gradle (it's inside your project) and change the both jcenter to mavenCentral

(you can do it in Global file too: C:\Program Files\AndroidStudio\plugins\android\lib\templates\gradle-projects\NewAndroidProject\root\build.gradle.ftl however, you will need to do this modification again after AndroidStudio upgrade)

I found that pathlib module also supports this.

from pathlib import Path
>>> Path.home()
WindowsPath('C:/Users/XXX')

This is working for me:

$user_info = DB::table('usermetas')
                 ->select('browser', DB::raw('count(*) as total'))
                 ->groupBy('browser')
                 ->get();

Try this:

if (rs != null && rs.first()) {
    do {
        count = rs.getInt(1);
    } while (rs.next());
}

Not sure whether this is still actual.. just for future readers. If what you really want is to pass your parameters as part of the URL, you should probably use jQuery.param().

numpy 1D array --> column/row matrix:

>>> a=np.array([1,2,4])
>>> a[:, None]    # col
array([[1],
       [2],
       [4]])
>>> a[None, :]    # row, or faster `a[None]`
array([[1, 2, 4]])

And as @joe-kington said, you can replace None with np.newaxis for readability.
