There is nothing built into bootstrap for this, but some simple css could fix it. Something like this should work. Not tested though

 @media (max-width: 768px) {
      .col-xs-12.text-right, .col-xs-12.text-left {
              text-align: center;
       } 
    }

The following works in MVC5:

document.getElementById('theID').value = 'new value';

None of the suggestions worked for me. I did not want to turn off this feature for the whole website anyhow because 99% time I do not want my users placing HTML on web forms. I just created my own work around method since I'm the only one using this particular application. I convert the input to HTML in the code behind and insert it into my database.

I'm the developer of Redux Auth and some of the issues you mentioned have been fixed in the version 2 beta. You can download this off the offcial website with a sample application too.

• Requires autoloading (impeding performance)
• Uses the inherently unsafe concept of 'security questions'. Dealbreaker!

Security questions are now not used and a simpler forgotten password system has been put in place.

• Return types are a bit of a hodgepodge of true, false, error and success codes

This was fixed in version 2 and returns boolean values. I hated the hodgepodge as much as you.

• Doesn't hook into CI's validation system

The sample application uses the CI's validation system.

• Doesn't allow a user to resend a 'lost password' code

Work in progress

I also implemented some other features such as email views, this gives you the choice of being able to use the CodeIgniter helpers in your emails.

It's still a work in progress so if have any more suggestions please keep them coming.

Ps : Thanks for recommending Redux.

In my case, I took an android project from one computer to another and had this problem. What worked for me was a combination of some of the answers I've seen:

• Remove the copy of the appcompat library that was in the libs folder of the workspace
• Install sdk 21
• Change the project properties to use that sdk build
• Set up and start an emulator compatible with sdks 21
• Update the Run Configuration to prompt for device to run on & choose Run

Mine ran fine after these steps.

May be the link will Help bcz u might have to implement the code in Appdelegate in app run in background method .. Also consult the developer.apple.com site for application class Here is link for runing app in background

Use \1 instead of $1.

\number Matches the contents of the group of the same number.

Folks above hit the right notes for storage, though if you also need to consider any PII data that needs to be stored then you can also stash into the keychain using something like https://github.com/oblador/react-native-keychain since ASyncStorage is unencrypted. It can be applied as part of the persist configuration in something like redux-persist.

I have met same problem. In my case I had no ..\data dir in my C:\mysql\ so I just executed mysqld --initialize command from c:\mysql\bin\ directory and I got the data directory in c:\mysql\data. Afterwards I could use mysqld.exe --console command to test the server startup.

<?php

  class Test {
     function MethodA(){
         echo __FUNCTION__ ;
     }
 }
 $test = new Test;
 echo $test->MethodA();
?>

Result: "MethodA";

To check if a folder exists or not, you can simply use the exists() method:

// Create a File object representing the folder 'A/B'
def folder = new File( 'A/B' )

// If it doesn't exist
if( !folder.exists() ) {
  // Create all folders up-to and including B
  folder.mkdirs()
}

// Then, write to file.txt inside B
new File( folder, 'file.txt' ).withWriterAppend { w ->
  w << "Some text\n"
}

If you are using Eclipse,

1. Open "Git Repositories"
2. Find your Repository.
3. Open up "Branches" then "Remote Tracking".

They should all be in there. Right click and "checkout."

Starting eclipse with eclipse -clean did wonders for me.

SELECT * FROM table
WHERE exec_datetime BETWEEN DATE_SUB(NOW(), INTERVAL 30 DAY) AND NOW();

If you are sure you want to remove all commit history, simply delete the .git directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:

git init
git remote add origin [email protected]:user/repo

now commit your current version of code

git add *
git commit -am 'message'

and finally force the update to GitHub:

git push -f origin master

However, I suggest backing up the history (the .git folder in the repository) before taking these steps!

For large files, what I did was read the file line by line and read each line into an array. Then, once the array reached a certain size, append it to a new file.

for line in open("file.txt", "r"):
    list.append(line)
    if len(list) == 1000000: 
        output.writelines(list)
        del list[:]

Try the format syntax:

print ("{0}. {1} appears {2} times.".format(1, 'b', 3.1415))

Outputs:

1. b appears 3.1415 times.

The print function is called just like any other function, with parenthesis around all its arguments.

The comment by @xicocaio should be highlighted.

tkinter is python version-specific in the sense that sudo apt-get install python3-tk will install tkinter exclusively for your default version of python. Suppose you have different python versions within various virtual environments, you will have to install tkinter for the desired python version used in that virtual environment. For example, sudo apt-get install python3.7-tk. Not doing this will still lead to No module named ' tkinter' errors, even after installing it for the global python version.

Okay, I have refined my regular expression based on the solution you came up with (which erroneously matches strings that start with 'test').

^((?!foo).)*$

This regular expression will match only strings that do not contain foo. The first lookahead will deny strings beginning with 'foo', and the second will make sure that foo isn't found elsewhere in the string.

Even though this is an old question, I 've stumbled upon this issue multiple times and until now never figured out how to fix it. The update maven indices is a term coined by IntelliJ, and if it still doesn't work after you've compiled the first project, chances are that you are using 2 different maven installations.

Press CTRL+Shift+A to open up the Actions menu. Type Maven and go to Maven Settings. Check the Home Directory to use the same maven as you use via the command line

Found one solution for WIFI (works for Android 4.3, 4.4):

1. Connect to WIFI network (e.g. 'Alex')
2. Settings->WIFI
3. Long tap on connected network's name (e.g. on 'Alex')
4. Modify network config-> Show advanced options
5. Set proxy settings

Leading from answers from @Bozho and @aioobe, lexicographic comparisons are similar to the ordering that one might find in a dictionary.

The Java String class provides the .compareTo () method in order to lexicographically compare Strings. It is used like this "apple".compareTo ("banana").

The return of this method is an int which can be interpreted as follows:

• returns < 0 then the String calling the method is lexicographically first (comes first in a dictionary)
• returns == 0 then the two strings are lexicographically equivalent
• returns > 0 then the parameter passed to the compareTo method is lexicographically first.

More specifically, the method provides the first non-zero difference in ASCII values.

Thus "computer".compareTo ("comparison") will return a value of (int) 'u' - (int) 'a' (20). Since this is a positive result, the parameter ("comparison") is lexicographically first.

There is also a variant .compareToIgnoreCase () which will return 0 for "a".compareToIgnoreCase ("A"); for example.

All javascript methods are applicable with angularjs because angularjs itself is a javascript framework so you can use indexOf() inside angular directives

<li ng-repeat="select in Items">   
         <foo ng-repeat="newin select.values">
<span ng-if="newin.label.indexOf(x) !== -1">{{newin.label}}</span></foo>
</li>
//where x is your character to be found

How do I remove unwanted parts from strings in a column?

6 years after the original question was posted, pandas now has a good number of "vectorised" string functions that can succinctly perform these string manipulation operations.

This answer will explore some of these string functions, suggest faster alternatives, and go into a timings comparison at the end.

.str.replace

Specify the substring/pattern to match, and the substring to replace it with.

pd.__version__
# '0.24.1'

df    
    time result
1  09:00   +52A
2  10:00   +62B
3  11:00   +44a
4  12:00   +30b
5  13:00  -110a

df['result'] = df['result'].str.replace(r'\D', '')
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

If you need the result converted to an integer, you can use Series.astype,

df['result'] = df['result'].str.replace(r'\D', '').astype(int)

df.dtypes
time      object
result     int64
dtype: object

If you don't want to modify df in-place, use DataFrame.assign:

df2 = df.assign(result=df['result'].str.replace(r'\D', ''))
df
# Unchanged

.str.extract

Useful for extracting the substring(s) you want to keep.

df['result'] = df['result'].str.extract(r'(\d+)', expand=False)
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

With extract, it is necessary to specify at least one capture group. expand=False will return a Series with the captured items from the first capture group.

.str.split and .str.get

Splitting works assuming all your strings follow this consistent structure.

# df['result'] = df['result'].str.split(r'\D').str[1]
df['result'] = df['result'].str.split(r'\D').str.get(1)
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

Do not recommend if you are looking for a general solution.

If you are satisfied with the succinct and readable str accessor-based solutions above, you can stop here. However, if you are interested in faster, more performant alternatives, keep reading.

Optimizing: List Comprehensions

In some circumstances, list comprehensions should be favoured over pandas string functions. The reason is because string functions are inherently hard to vectorize (in the true sense of the word), so most string and regex functions are only wrappers around loops with more overhead.

My write-up, Are for-loops in pandas really bad? When should I care?, goes into greater detail.

The str.replace option can be re-written using re.sub

import re

# Pre-compile your regex pattern for more performance.
p = re.compile(r'\D')
df['result'] = [p.sub('', x) for x in df['result']]
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

The str.extract example can be re-written using a list comprehension with re.search,

p = re.compile(r'\d+')
df['result'] = [p.search(x)[0] for x in df['result']]
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

If NaNs or no-matches are a possibility, you will need to re-write the above to include some error checking. I do this using a function.

def try_extract(pattern, string):
    try:
        m = pattern.search(string)
        return m.group(0)
    except (TypeError, ValueError, AttributeError):
        return np.nan

p = re.compile(r'\d+')
df['result'] = [try_extract(p, x) for x in df['result']]
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

We can also re-write @eumiro's and @MonkeyButter's answers using list comprehensions:

df['result'] = [x.lstrip('+-').rstrip('aAbBcC') for x in df['result']]

And,

df['result'] = [x[1:-1] for x in df['result']]

Same rules for handling NaNs, etc, apply.

Performance Comparison

Graphs generated using perfplot. Full code listing, for your reference. The relevant functions are listed below.

Some of these comparisons are unfair because they take advantage of the structure of OP's data, but take from it what you will. One thing to note is that every list comprehension function is either faster or comparable than its equivalent pandas variant.

Functions

def eumiro(df):
    return df.assign(
        result=df['result'].map(lambda x: x.lstrip('+-').rstrip('aAbBcC')))

def coder375(df):
    return df.assign(
        result=df['result'].replace(r'\D', r'', regex=True))

def monkeybutter(df):
    return df.assign(result=df['result'].map(lambda x: x[1:-1]))

def wes(df):
    return df.assign(result=df['result'].str.lstrip('+-').str.rstrip('aAbBcC'))

def cs1(df):
    return df.assign(result=df['result'].str.replace(r'\D', ''))

def cs2_ted(df):
    # `str.extract` based solution, similar to @Ted Petrou's. so timing together.
    return df.assign(result=df['result'].str.extract(r'(\d+)', expand=False))

def cs1_listcomp(df):
    return df.assign(result=[p1.sub('', x) for x in df['result']])

def cs2_listcomp(df):
    return df.assign(result=[p2.search(x)[0] for x in df['result']])

def cs_eumiro_listcomp(df):
    return df.assign(
        result=[x.lstrip('+-').rstrip('aAbBcC') for x in df['result']])

def cs_mb_listcomp(df):
    return df.assign(result=[x[1:-1] for x in df['result']])

You can replace your old dictionary with a defaultdict:

>>> from collections import defaultdict
>>> d = {'foo': 123, 'bar': 456}
>>> d['baz']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'baz'
>>> d = defaultdict(lambda: -1, d)
>>> d['baz']
-1

The "trick" here is that a defaultdict can be initialized with another dict. This means that you preserve the existing values in your normal dict:

>>> d['foo']
123

You can use the one below. I tested this with leading zero bytes and with initial negative bytes as well

public static String toHex(byte[] bytes) {
    BigInteger bi = new BigInteger(1, bytes);
    return String.format("%0" + (bytes.length << 1) + "X", bi);
}

If you want lowercase hex digits, use "x" in the format String.

To include JS and CSS files in a specific view you can do it via controller by passing the parameters false, true, which will include the CSS and JS for, e.g.:

$this->renderPartial(
    'yourviewname',
    array(
        'model' => $model,
        false,
        true
    )
);

Premise

There is no standard naming of keys in JSON. According to the Objects section of the spec:

The JSON syntax does not impose any restrictions on the strings used as names,...

Which means camelCase or snake_case should work fine.

Driving factors

Imposing a JSON naming convention is very confusing. However, this can easily be figured out if you break it down into components.

1. Programming language for generating JSON

   • Python - snake_case
   • PHP - snake_case
   • Java - camelCase
   • JavaScript - camelCase

2. JSON itself has no standard naming of keys

3. Programming language for parsing JSON

   • Python - snake_case
   • PHP - snake_case
   • Java - camelCase
   • JavaScript - camelCase

Mix-match the components

1. Python » JSON » Python - snake_case - unanimous
2. Python » JSON » PHP - snake_case - unanimous
3. Python » JSON » Java - snake_case - please see the Java problem below
4. Python » JSON » JavaScript - snake_case will make sense; screw the front-end anyways
5. Python » JSON » you do not know - snake_case will make sense; screw the parser anyways
6. PHP » JSON » Python - snake_case - unanimous
7. PHP » JSON » PHP - snake_case - unanimous
8. PHP » JSON » Java - snake_case - please see the Java problem below
9. PHP » JSON » JavaScript - snake_case will make sense; screw the front-end anyways
10. PHP » JSON » you do not know - snake_case will make sense; screw the parser anyways
11. Java » JSON » Python - snake_case - please see the Java problem below
12. Java » JSON » PHP - snake_case - please see the Java problem below
13. Java » JSON » Java - camelCase - unanimous
14. Java » JSON » JavaScript - camelCase - unanimous
15. Java » JSON » you do not know - camelCase will make sense; screw the parser anyways
16. JavaScript » JSON » Python - snake_case will make sense; screw the front-end anyways
17. JavaScript » JSON » PHP - snake_case will make sense; screw the front-end anyways
18. JavaScript » JSON » Java - camelCase - unanimous
19. JavaScript » JSON » JavaScript - camelCase - Original

Java problem

snake_case will still make sense for those with Java entries because the existing JSON libraries for Java are using only methods to access the keys instead of using the standard dot.syntax. This means that it wouldn't hurt that much for Java to access the snake_cased keys in comparison to the other programming language which can do the dot.syntax.

Example for Java's org.json package

JsonObject.getString("snake_cased_key")

Example for Java's com.google.gson package

JsonElement.getAsString("snake_cased_key")

Some actual implementations

• Google Maps JavaScript API - camelCased
• Facebook JavaScript API - snake_cased
• Amazon Web Services - snake_cased & camelCased
• Twitter API - snake_cased
• JSON-LD - camelCased & ProperCamelCased

Conclusions

Choosing the right JSON naming convention for your JSON implementation depends on your technology stack. There are cases where one can use snake_case, camelCase, or any other naming convention.

Another thing to consider is the weight to be put on the JSON-generator vs the JSON-parser and/or the front-end JavaScript. In general, more weight should be put on the JSON-generator side rather than the JSON-parser side. This is because business logic usually resides on the JSON-generator side.

Also, if the JSON-parser side is unknown then you can declare what ever can work for you.

Match against the pattern and use the host language to invert the boolean result of the match. This will be much more legible and maintainable.

I resolved it by :

1) Sync Project with gradle files
2) Build -> Clean Project
3) Build -> Rebuild Project
4) File -> Invalidate caches

//imp step
5) Check your xml files properly.

add this in your styles.xml

        <style name="Divider">
            <item name="android:layout_width">1dip</item>
            <item name="android:layout_height">match_parent</item>
            <item name="android:background">@color/divider_color</item>
        </style>

        <style name="Divider_invisible">
            <item name="android:layout_width">1dip</item>
            <item name="android:layout_height">match_parent</item>
        </style>

then wrap this style in a linear layout where you want the vertical line, I used the vertical line as a column divider in my table. 

     <TableLayout
                android:id="@+id/table"
                android:layout_width="match_parent"

Because there might be a standard way you want to instantiate data in the abstract class. That way you can have classes that inherit from that class call the base constructor.

public abstract class A{

    private string data;

    protected A(string myString){
      data = myString;
    }

}

public class B : A {

     B(string myString) : base(myString){}

}

rank() : It is used to rank a record within a group of rows.

dense_rank() : The DENSE_RANK function acts like the RANK function except that it assigns consecutive ranks.

Short trick: after I only REMOVED SPACES from names of the folders, where the .jar file was, double-clicked worked and the file executed.

From the keytool man - it imports certificate chain, if input is given in PKCS#7 format, otherwise only the single certificate is imported. You should be able to convert certificates to PKCS#7 format with openssl, via openssl crl2pkcs7 command.

Arrays:

{{#each array}}
    {{@index}}: {{this}}
{{/each}}

If you have arrays of objects... you can iterate through the children:

{{#each array}}
    //each this = { key: value, key: value, ...}
    {{#each this}}
        //each key=@key and value=this of child object 
        {{@key}}: {{this}}
        //Or get index number of parent array looping
        {{@../index}}
    {{/each}}
{{/each}}

Objects:

{{#each object}}
    {{@key}}: {{this}}
{{/each}} 

If you have nested objects you can access the key of parent object with {{@../key}}

Be sure to include the $route service into your scope and do this:

$route.reload();

How to reload or re-render the entire page using AngularJS

This is not the best practice in .NET framework (4 & +) to check equality

String.Compare(x.Username, (string)drUser["Username"], 
                  StringComparison.OrdinalIgnoreCase) == 0

Use the following instead

String.Equals(x.Username, (string)drUser["Username"], 
                   StringComparison.OrdinalIgnoreCase) 

MSDN recommends:

• Use an overload of the String.Equals method to test whether two strings are equal.
• Use the String.Compare and String.CompareTo methods to sort strings, not to check for equality.

You probably want to use a regex like the one described here to check the format. When the form's submitted, run the following test on each field:

var userinput = $(this).val();
var pattern = /^\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b$/i

if(!pattern.test(userinput))
{
  alert('not a valid e-mail address');
}?

 $(function () {
     $('input[type=checkbox]').click(function () {
         var chks = document.getElementById('<%= chkRoleInTransaction.ClientID %>').getElementsByTagName('INPUT');
         for (i = 0; i < chks.length; i++) {
            chks[i].checked = false;
         }
         if (chks.length > 1)
            $(this)[0].checked = true;
     });
 });

                        alertDialog.setCancelable(true); // HERE

                    }
                });

                return true;
            }
        });

First of all, let's try to make your code a little simpler:

// No need to create a circle unless it is clearly necessary to
// demonstrate the problem

// Your Rect2f defines a default constructor, so let's use it for simplicity.
shared_ptr<Shape> rect(new Rect2f());

Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:

int main() {
    delete new T();
}

This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:

In function 'int main()':
Line 2: error: expected type-specifier before 'T'

Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f.

I'd go with boost::filesystem::extension (std::filesystem::path::extension with C++17) but if you cannot use Boost and you just have to verify the extension, a simple solution is:

bool ends_with(const std::string &filename, const std::string &ext)
{
  return ext.length() <= filename.length() &&
         std::equal(ext.rbegin(), ext.rend(), filename.rbegin());
}

if (ends_with(filename, ".conf"))
{ /* ... */ }

Find the project's folder in your system, enter it's Properties via context menu and deselect "Read only" option. Worked in my case.

This seems to be the source of the problem in many cases, moreover some solutions up there base on copying/rewriting the files in the project what makes them non-read-only.

You are most likely looking for the IIS_IUSRS account.

1: The LayoutInflater takes your layout XML-files and creates different View-objects from its contents.

2: The adapters are built to reuse Views, when a View is scrolled so that is no longer visible, it can be used for one of the new Views appearing. This reused View is the convertView. If this is null it means that there is no recycled View and we have to create a new one, otherwise we should use it to avoid creating a new.

3: The parent is provided so you can inflate your view into that for proper layout parameters.

All these together can be used to effectively create the view that will appear in your list (or other view that takes an adapter):

public View getView(int position, @Nullable View convertView, ViewGroup parent){
    if (convertView == null) {
        //We must create a View:
        convertView = inflater.inflate(R.layout.my_list_item, parent, false);
    }
    //Here we can do changes to the convertView, such as set a text on a TextView 
    //or an image on an ImageView.
    return convertView;
}

Notice the use of the LayoutInflater, that parent can be used as an argument for it, and how convertView is reused.

Obscure but important detail: if you say "for(auto it)" as follows, you get a copy of the object, not the actual element:

struct Xs{int i} x;
x.i = 0;
vector <Xs> v;
v.push_back(x);
for(auto it : v)
    it.i = 1;         // doesn't change the element v[0]

To modify the elements of the vector, you need to define the iterator as a reference:

for(auto &it : v)

With Windows 2012 R2 (Win 8.1) and up, you also have the "official" Import-PfxCertificate cmdlet

Here are some essential parts of code (an adaptable example):

Invoke-Command -ComputerName $Computer -ScriptBlock {
        param(
            [string] $CertFileName,
            [string] $CertRootStore,
            [string] $CertStore,
            [string] $X509Flags,
            $PfxPass)
        $CertPath = "$Env:SystemRoot\$CertFileName"
        $Pfx = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
        # Flags to send in are documented here: https://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509keystorageflags%28v=vs.110%29.aspx
        $Pfx.Import($CertPath, $PfxPass, $X509Flags) #"Exportable,PersistKeySet")
        $Store = New-Object -TypeName System.Security.Cryptography.X509Certificates.X509Store -ArgumentList $CertStore, $CertRootStore
        $Store.Open("MaxAllowed")
        $Store.Add($Pfx)
        if ($?)
        {
            "${Env:ComputerName}: Successfully added certificate."
        }
        else
        {
            "${Env:ComputerName}: Failed to add certificate! $($Error[0].ToString() -replace '[\r\n]+', ' ')"
        }
        $Store.Close()
        Remove-Item -LiteralPath $CertPath
    } -ArgumentList $TempCertFileName, $CertRootStore, $CertStore, $X509Flags, $Password

Based on mao47's code and some research, I wrote up a little article and a simple cmdlet for importing/pushing PFX certificates to remote computers.

Here's my article with more details and complete code that also works with PSv2 (default on Server 2008 R2 / Windows 7), so long as you have SMB enabled and administrative share access.

The only way I know to deal with this is to create a new workspace, import projects from the polluted workspace, reconstructing all my settings (a major pain) and then delete the old workspace. Is there an easier way to deal with this?

For synchronizing or restoring all our settings we use Workspace Mechanic. Once all the settings are recorded its one click and all settings are restored... You can also setup a server which provides those settings for all users.

This works:

var num = parseFloat(document.getElementById(amtid4).innerHTML, 10).toFixed(2);

You can refer to this page at w3schools but basically you could use any of:

<input checked>
<input checked="checked">
<input checked="">

Well, apparently I had to change my PUT calling function updateUser. I removed the @Consumes, the @RequestMapping and also added a @ResponseBody to the function. So my method looked like this:

@RequestMapping(value="/{id}",method = RequestMethod.PUT)
@ResponseStatus(HttpStatus.OK)
@ResponseBody
public void updateUser(@PathVariable int id, @RequestBody User temp){
    Set<User> set1= obj2.getUsers();
    for(User a:set1)
    {
        if(id==a.getId())
        {
            set1.remove(a);
            a.setId(temp.getId());
            a.setName(temp.getName());
            set1.add(a);
        }
    }
    Userlist obj3=new Userlist(set1);
    obj2=obj3;
}

And it worked!!! Thank you all for the response.

1) Change your .net profile from Client profile to to .Net Framework 4.0 http://msdn.microsoft.com/en-us/library/bb398202.aspx

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

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

Was looking for a file/folder browser myself recently and decided to make a new explorer activity (Android library): https://github.com/vaal12/AndroidFileBrowser

Matching Test application https://github.com/vaal12/FileBrowserTestApplication- is a sample how to use.

Allows picking directories and files from phone file structure.

By far the simplest command for this is:

git show --name-only

As it lists just the files in the last commit and doesn't give you the entire guts

I totally do not get it, why everyone is suggesting the genric type over the array particularly for this question.

What if my need is to index n different arraylists.

With declaring List<List<Integer>> I need to create n ArrayList<Integer> objects manually or put a for loop to create n lists or some other way, in any way it will always be my duty to create n lists.

Isn't it great if we declare it through casting as List<Integer>[] = (List<Integer>[]) new List<?>[somenumber]. I see it as a good design where one do not have to create all the indexing object (arraylists) by himself

Can anyone enlighten me why this (arrayform) will be a bad design and what are its disadvantages?

You just need to cast it, as such:

int intPart = (int)343564564.4342

If you still want to use it as a decimal in later calculations, then Math.Truncate (or possibly Math.Floor if you want a certain behaviour for negative numbers) is the function you want.

vi /usr/local/etc/redis.conf

Look for dir, logfile

# The working directory.
#
# The DB will be written inside this directory, with the filename specified
# above using the 'dbfilename' configuration directive.
#
# The Append Only File will also be created inside this directory.
#
# Note that you must specify a directory here, not a file name.
dir /usr/local/var/db/redis/



# Specify the log file name. Also the empty string can be used to force
# Redis to log on the standard output. Note that if you use standard
# output for logging but daemonize, logs will be sent to /dev/null 
logfile "redis_log"

So the log file is created at /usr/local/var/db/redis/redis_log with the name redis_log

You can also try MONITOR command from redis-cli to review the number of commands executed.

You might also consider the smart_open module, which supports iterators:

from smart_open import smart_open

# stream lines from an S3 object
for line in smart_open('s3://mybucket/mykey.txt', 'rb'):
    print(line.decode('utf8'))

and context managers:

with smart_open('s3://mybucket/mykey.txt', 'rb') as s3_source:
    for line in s3_source:
         print(line.decode('utf8'))

    s3_source.seek(0)  # seek to the beginning
    b1000 = s3_source.read(1000)  # read 1000 bytes

Find smart_open at https://pypi.org/project/smart_open/

For people using Bootstrap, use $(#elementId').selectpicker('val','elementValue') instead of $('#elementId').val('elementValue'), as the latter does not update the value in the UI.

Note: Even .change() function works, as suggested above in some answers, but it triggers the $('#elementId').change(function(){ //do something }) function.

Just posting this out there for people referencing this thread in the future.

like the answer above but I have a duplicate record so I have to create a subquery with distinct

Select user_id
(
   select distinct userid
   from yourtable
   where user_id = @userid

) t1
where 
ancestry in ('England', 'France', 'Germany')
group by user_id
having count(user_id) = 3

this is what I used because I have multiple record(download logs) and this checks that all the required files have been downloaded

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 .

The following script set the sequence to a desired value:

Given a freshly created sequence named PCS_PROJ_KEY_SEQ and table PCS_PROJ:

BEGIN
   DECLARE
      PROJ_KEY_MAX       NUMBER := 0;
      PROJ_KEY_CURRVAL   NUMBER := 0;
   BEGIN

    SELECT MAX (PROJ_KEY) INTO PROJ_KEY_MAX FROM PCS_PROJ;
    EXECUTE IMMEDIATE 'ALTER SEQUENCE PCS_PROJ_KEY_SEQ INCREMENT BY ' || PROJ_KEY_MAX;
    SELECT PCS_PROJ_KEY_SEQ.NEXTVAL INTO PROJ_KEY_CURRVAL FROM DUAL;
    EXECUTE IMMEDIATE 'ALTER SEQUENCE PCS_PROJ_KEY_SEQ INCREMENT BY 1';

END;
END;
/

Yes there is a difference in the performance of both: jQuery('#id').show() is slower than jQuery('#id').css("display","block") as in former case extra work is to be done for retrieving the initial state from the jquery cache as display is not a binary attribute it can be inline,block,none,table, etc. similar is the case with hide() method.

See: http://jsperf.com/show-vs-addclass

ssize_t is used for functions whose return value could either be a valid size, or a negative value to indicate an error. It is guaranteed to be able to store values at least in the range [-1, SSIZE_MAX] (SSIZE_MAX is system-dependent).

So you should use size_t whenever you mean to return a size in bytes, and ssize_t whenever you would return either a size in bytes or a (negative) error value.

See: http://pubs.opengroup.org/onlinepubs/007908775/xsh/systypes.h.html

I like to used this method the most, it will auto select the first column to the last column being used. However, if the last cell in the first row or the last cell in the first column are empty, this code will not calculate properly. Check the link for other methods to dynamically select cell range.

Sub DynamicRange()
'Best used when first column has value on last row and first row has a value in the last column

Dim sht As Worksheet
Dim LastRow As Long
Dim LastColumn As Long
Dim StartCell As Range

Set sht = Worksheets("Sheet1")
Set StartCell = Range("A1")

'Find Last Row and Column
  LastRow = sht.Cells(sht.Rows.Count, StartCell.Column).End(xlUp).Row
  LastColumn = sht.Cells(StartCell.Row, sht.Columns.Count).End(xlToLeft).Column

'Select Range
  sht.Range(StartCell, sht.Cells(LastRow, LastColumn)).Select

End Sub

You can't change the build output folder name with the current configuration options.

Moreover, you shouldn't. This is a part of the philosophy behind create-react-app: they say Convention over Configuration.

If you really need to rename your folder, I see two options:

1. Right after the build process finishes, write a command that copies the build folder content to another folder you want. For example you can try the copyfiles npm package, or anything similar.

2. You could try to eject create-react-app and tweak the configuration.

   If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

   Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

   However, it is important to note that this is a one-way operation. Once you eject, you can’t go back! You loose all future updates.

Therefore, I'd recommend you to not use a custom folder naming, if possible. Try to stick with the default naming. If not an option, try #1. If it still doesn't work for your specific use-case and you're really out of options - explore #2. Good luck!

If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents

export JAVA_OPTS="-server -Xmx512m"

For Windows you will need, in setenv.bat, something like

set JAVA_OPTS=-server -Xmx768m

Original answer here

After you run startup.bat, you can easily confirm the correct settings have been applied provided you have turned @echo on somewhere in your catatlina.bat file (a good place could be immediately after echo Using CLASSPATH: "%CLASSPATH%"):

This is basically available in a 'protected' attribute of the Enum class:

list(Color._value2member_map_.keys())

If you are using JPanels, then are probably working with Swing. Try this:

BufferedImage myPicture = ImageIO.read(new File("path-to-file"));
JLabel picLabel = new JLabel(new ImageIcon(myPicture));
add(picLabel);

The image is now a swing component. It becomes subject to layout conditions like any other component.

 @Html.TextBoxFor(m => m.UserName, new { @class = "form-control",@placeholder = "Name"  })  

I've always used the term "magic number" differently, as an obscure value stored within a data structure which can be verified as a quick validity check. For example gzip files contain 0x1f8b08 as their first three bytes, Java class files start with 0xcafebabe, etc.

You often see magic numbers embedded in file formats, because files can be sent around rather promiscuously and lose any metadata about how they were created. However magic numbers are also sometimes used for in-memory data structures, like ioctl() calls.

A quick check of the magic number before processing the file or data structure allows one to signal errors early, rather than schlep all the way through potentially lengthy processing in order to announce that the input was complete balderdash.

You should look into the strtotime() function.

Since position: absolute; and viewport width were no options in my special case, there is another quick solution to solve the problem. The only condition is, that overflow in x-direction is not necessary for your website.

You can define negative margins for your element:

#help_panel {
    margin-left: -9999px;
    margin-right: -9999px;
}

But since we get overflow doing this, we have to avoid overflow in x-direction globally e.g. for body:

body {
    overflow-x: hidden;
}

You can set padding to choose the size of your content.

Note that this solution does not bring 100% width for content, but it is helpful in cases where you need e.g. a background color which has full width with a content still depending on container.

While specifying spellcheck="false" in the < tag > will certainly disable that feature, it's handy to be able to toggle that functionality on and off as needed after the page has loaded. So here's a non-jQuery way to set the spellcheck attribute programmatically:

:

<textarea id="my-ta" spellcheck="whatever">abcd dcba</textarea>

:

function setSpellCheck( mode ) {
    var myTextArea = document.getElementById( "my-ta" )
        , myTextAreaValue = myTextArea.value
    ;
    myTextArea.value = '';
    myTextArea.setAttribute( "spellcheck", String( mode ) );
    myTextArea.value = myTextAreaValue;
    myTextArea.focus();
}

:

setSpellCheck( true );
setSpellCheck( 'false' );

The function argument may be either boolean or string.

No need to loop through the textarea contents, we just cut 'n paste what's there, and then set focus.

use the variable, Oracle does not support SQL in that context without an INTO. With a properly named variable your code will be more legible anyway.

Try it like this instead, move your myclass items inside a main method:

    class UserInput {
      public void name() {
        System.out.println("This is a test.");
      }
    }

    public class MyClass {

        public static void main( String args[] )
        {
            UserInput input = new UserInput();
            input.name();
        }

    }

You can do this to ignore all nulls in an object you're serializing, and any null properties won't then appear in the JSON

JsonSerializerSettings settings = new JsonSerializerSettings();
settings.NullValueHandling = NullValueHandling.Ignore;
var myJson = JsonConvert.SerializeObject(myObject, settings);

If you could use Ant then you would just use the JUnitReport task as detailed here: http://ant.apache.org/manual/Tasks/junitreport.html, but you mentioned in your question that you're not supposed to use Ant. I believe that task merely transforms the XML report into HTML so it would be feasible to use any XSLT processor to generate a similar report.

Alternatively, you could switch to using TestNG ( http://testng.org/doc/index.html ) which is very similar to JUnit but has a default HTML report as well as several other cool features.

Adding a bit to mitigate the confusion here. Even though Darren Davies' (accepted) answer is more straight forward, I think Andrei's answer is a better approach for MVC applications.

The answer from Andrei means that you can use HttpContext just as you would use System.Web.HttpContext.Current. For example, if you want to do this:

System.Web.HttpContext.Current.User.Identity.Name

you should instead do this:

HttpContext.User.Identity.Name

Both achieve the same result, but (again) in terms of MVC, the latter is more recommended.

Another good and also straight forward information regarding this matter can be found here: Difference between HttpContext.Current and Controller.Context in MVC ASP.NET.

if pthread_t is just a number; this would be the easiest.

int get_tid(pthread_t tid)

    return *threadid;
}

The advantages of EditorFor is that your code is not tied to an <input type="text". So if you decide to change something to the aspect of how your textboxes are rendered like wrapping them in a div you could simply write a custom editor template (~/Views/Shared/EditorTemplates/string.cshtml) and all your textboxes in your application will automatically benefit from this change whereas if you have hardcoded Html.TextBoxFor you will have to modify it everywhere. You could also use Data Annotations to control the way this is rendered.

I think I've done something similar with:

svn add . --recursive

None of the links above about lib and lib32 folder worked for me with Oracle Client 11.2.0 But I found this on the OTN community:

As far as inspecting a client install to try to tell if it's 32 bit or 64 bit, you can check the registry, a 32 bit home will be located in HKLM>Software>WOW6432Node>Oracle, whereas a 64 bit home will be in HKLM>Software>Oracle.

Try below solution, This will also take care when a user enters only blank space in the input field at the first index.

document.getElementById('capitalizeInput').addEventListener("keyup",   () => {_x000D_
  var inputValue = document.getElementById('capitalizeInput')['value']; _x000D_
  if (inputValue[0] === ' ') {_x000D_
      inputValue = '';_x000D_
    } else if (inputValue) {_x000D_
      inputValue = inputValue[0].toUpperCase() + inputValue.slice(1);_x000D_
    }_x000D_
document.getElementById('capitalizeInput')['value'] = inputValue;_x000D_
});

<input type="text" id="capitalizeInput" autocomplete="off" />

Such difference between the output of du -sh and df -h may happen if some large file has been deleted, but is still opened by some process. Check with the command lsof | grep deleted to see which processes have opened descriptors to deleted files. You can restart the process and the space will be freed.

it worked for me using this line of code:

<a id="LinkTest" title="Any Title"  href="#" onclick="Function(); return false; ">text</a>

The answer given above can't solve my problem.So I change async into false to get the alert message.

            data: {action: 'submit_data', info: info},
            success: function(data) {
                alert("Data was succesfully captured");
            },
        });

As Martin Smith said, if you have no access to the machine or the filesystem, you will need to use third party tools, like Red Gate or Adept to do a compare on the source and destination systems. Red Gate's tools will allow you to copy the objects and schemas AND the data.

Change the rule on your <a> element from:

.navigation ul a {
    color: #000;
    display: block;
    padding: 0 65px 0 0;
    text-decoration: none;
}?

to

.navigation ul a {
    color: #000;
    display: block;
    padding: 0 65px 0 0;
    text-decoration: none;
    width:100%;
    text-align:center;
}?

Just add two new rules (width:100%; and text-align:center;). You need to make the anchor expand to take up the full width of the list item and then text-align center it.

Simple solution to emit and show message by Exception.

try {
  throw new TypeError("Error message");
}
catch (e){
  console.log((<Error>e).message);//conversion to Error type
}

Caution

Above is not a solution if we don't know what kind of error can be emitted from the block. In such cases type guards should be used and proper handling for proper error should be done - take a look on @Moriarty answer.

If you want to go with any certain commit or want to code of any certain commit then you can use below command:

When your certificate expires, it simply disappears from the ‘Certificates, Identifier & Profiles’ section of Member Center. There is no ‘Renew’ button that allows you to renew your certificate. You can revoke a certificate and generate a new one before it expires. Or you can wait for it to expire and disappear, then generate a new certificate. In Apple's App Distribution Guide:

Replacing Expired Certificates

When your development or distribution certificate expires, remove it and request a new certificate in Xcode.

When your certificate expires or is revoked, any provisioning profile that made use of the expired/revoked certificate will be reflected as ‘Invalid’. You cannot build and sign any app using these invalid provisioning profiles. As you can imagine, I'd rather revoke and regenerate a certificate before it expires.

Q: If I do that then will all my live apps be taken down?

Apps that are already on the App Store continue to function fine. Again, in Apple's App Distribution Guide:

Important: Re-creating your development or distribution certificates doesn’t affect apps that you’ve submitted to the store nor does it affect your ability to update them.

So…

Q: How to I properly renew it?

As mentioned above, there is no renewing of certificates. Follow the steps below to revoke and regenerate a new certificate, along with the affected provisioning profiles. The instructions have been updated for Xcode 8.3 and Xcode 9.

Step 1: Revoke the expiring certificate

Login to Member Center > Certificates, Identifiers & Profiles, select the expiring certificate. Take note of the expiry date of the certificate, and click the ‘Revoke’ button.

Step 2: (Optional) Remove the revoked certificate from your Keychain

Optionally, if you don't want to have the revoked certificate lying around in your system, you can delete them from your system. Unfortunately, the ‘Delete Certificate’ function in Xcode > Preferences > Accounts > [Apple ID] > Manage Certificates… seems to be always disabled, so we have to delete them manually using Keychain Access.app (/Applications/Utilities/Keychain Access.app).

Filter by ‘login’ Keychains and ‘Certificates’ Category. Locate the certificate that you've just revoked in Step 1.

Depending on the certificate that you've just revoked, search for either ‘Mac’ or ‘iPhone’. Mac App Store distribution certificates begin with “3rd Party Mac Developer”, and iOS App Store distribution certificates begin with “iPhone Distribution”.

You can locate the revoked certificate based on the team name, the type of certificate (Mac or iOS) and the expiry date of the certificate you've noted down in Step 1.

Step 3: Request a new certificate using Xcode

Under Xcode > Preferences > Accounts > [Apple ID] > Manage Certificates…, click on the ‘+’ button on the lower left, and select the same type of certificate that you've just revoked to let Xcode request a new one for you.

Step 4: Update your provisioning profiles to use the new certificate

After which, head back to Member Center > Certificates, Identifiers & Profiles > Provisioning Profiles > All. You'll notice that any provisioning profile that made use of the revoked certificate is now reflected as ‘Invalid’.

Click on any profile that are now ‘Invalid’, click ‘Edit’, then choose the newly created certificate, then click on ‘Generate’. Repeat this until all provisioning profiles are regenerated with the new certificate.

Step 5: Use Xcode to download the new provisioning profiles

Tip: Before you download the new profiles using Xcode, you may want to clear any existing and possibly invalid provisioning profiles from your Mac. You can do so by removing all the profiles from ~/Library/MobileDevice/Provisioning Profiles

Back in Xcode > Preferences > Accounts > [Apple ID], click on the ‘Download All Profiles’ button to ask Xcode to download all the provisioning profiles from your developer account.

1. Building off @Warewolf's answer, the next step is to create your own custom cell.

   Go to File -> New -> File -> User Interface -> Empty -> Call this nib "customNib".

2. In your customNib drag a UICollectionView Cell in. Give it reuse cell identifier @"Cell".

3. File -> New -> File -> Cocoa Touch Class -> Class named "CustomCollectionViewCell" subclass if UICollectionViewCell.

4. Go back to the custom nib, click cell and make this custom class "CustomCollectionViewCell".

5. Go to your viewDidLoad viewcontroller and instead of

   [_collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:@"cellIdentifier"];

   have

   UINib *nib = [UINib nibWithNibName:@"customNib" bundle:nil]; [_collectionView registerNib:nib forCellWithReuseIdentifier:@"Cell"];

6. Also, change (to your new cell identifier)

   UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];

Update: created a js fiddle here to see it live: http://jsfiddle.net/HFMvX/

I went through tons of google searches and didn't find anything satisfying. i like how passpack have done it so essentially reverse-engineered their approach, here we go:

function scorePassword(pass) {
    var score = 0;
    if (!pass)
        return score;

    // award every unique letter until 5 repetitions
    var letters = new Object();
    for (var i=0; i<pass.length; i++) {
        letters[pass[i]] = (letters[pass[i]] || 0) + 1;
        score += 5.0 / letters[pass[i]];
    }

    // bonus points for mixing it up
    var variations = {
        digits: /\d/.test(pass),
        lower: /[a-z]/.test(pass),
        upper: /[A-Z]/.test(pass),
        nonWords: /\W/.test(pass),
    }

    var variationCount = 0;
    for (var check in variations) {
        variationCount += (variations[check] == true) ? 1 : 0;
    }
    score += (variationCount - 1) * 10;

    return parseInt(score);
}

Good passwords start to score around 60 or so, here's function to translate that in words:

function checkPassStrength(pass) {
    var score = scorePassword(pass);
    if (score > 80)
        return "strong";
    if (score > 60)
        return "good";
    if (score >= 30)
        return "weak";

    return "";
}

you might want to tune this a bit but i found it working for me nicely

function isEmptyOrSpaces(str){
    return str === null || str.match(/^[\s\n\r]*$/) !== null;
}

You may also use box-shadow and add transparency to that dashed border via background-clip to let you see body background.

Pen to play with

render in firefox:

I think what you're trying to do is:

-(void) score2 {
    [self score];
}

The [object message] syntax is the normal way to call a method in objective-c. I think the @selector syntax is used when the method to be called needs to be determined at run-time, but I don't know objective-c well enough to give you more information on that.

If you want to load the view from the same controller you are on:

if ($validator->fails()) {
    return self::index($request)->withErrors($validator->errors());
}

And if you want to quickly display all errors but have a bit more control:

 @if ($errors->any())
     @foreach ($errors->all() as $error)
         <div>{{$error}}</div>
     @endforeach
 @endif

For fullscreen of browser rendering area there is a simple solution supported by all modern browsers.

div#placeholder {
    height: 100vh;
}

The only notable exception is the Android below 4.3 - but ofc only in the system browser/webview element (Chrome works ok).

Browser support chart: http://caniuse.com/viewport-units

For fullscreen of monitor please use HTML5 Fullscreen API

These answers, including the selected answer, are good for introducing promises conceptually, but lacking in specifics of what exactly the differences are in the terminology that arises when using libraries implementing them (and there are important differences).

Since it is still an evolving spec, the answer currently comes from attempting to survey both references (like wikipedia) and implementations (like jQuery):

• Deferred: Never described in popular references, ^{1 2 3 4} but commonly used by implementations as the arbiter of promise resolution (implementing resolve and reject). ^{5 6 7}

  Sometimes deferreds are also promises (implementing then), ^{5 6} other times it's seen as more pure to have the Deferred only capable of resolution, and forcing the user to access the promise for using then. ⁷

• Promise: The most all-encompasing word for the strategy under discussion.

  A proxy object storing the result of a target function whose synchronicity we would like to abstract, plus exposing a then function accepting another target function and returning a new promise. ²

  Example from CommonJS:

  > asyncComputeTheAnswerToEverything()
      .then(addTwo)
      .then(printResult);
  44
  

   

  Always described in popular references, although never specified as to whose responsibility resolution falls to. ^{1 2 3 4}

  Always present in popular implementations, and never given resolution abilites. ^{5 6 7}

• Future: a seemingly deprecated term found in some popular references ¹ and at least one popular implementation, ⁸ but seemingly being phased out of discussion in preference for the term 'promise' ³ and not always mentioned in popular introductions to the topic. ⁹

  However, at least one library uses the term generically for abstracting synchronicity and error handling, while not providing then functionality. ¹⁰ It's unclear if avoiding the term 'promise' was intentional, but probably a good choice since promises are built around 'thenables.' ²

The whole concept of inversion of control means you are free from a chore to instantiate objects manually and provide all necessary dependencies. When you annotate class with appropriate annotation (e.g. @Service) Spring will automatically instantiate object for you. If you are not familiar with annotations you can also use XML file instead. However, it's not a bad idea to instantiate classes manually (with the new keyword) in unit tests when you don't want to load the whole spring context.

Although this question has already been answered, I think this approach is better : http://jsfiddle.net/kjy112/3CvaD/ extract from this question on StackOverFlow google maps - open marker infowindow given the coordinates:

Each marker gets an "infowindow" entry :

function createMarker(lat, lon, html) {
    var newmarker = new google.maps.Marker({
        position: new google.maps.LatLng(lat, lon),
        map: map,
        title: html
    });

    newmarker['infowindow'] = new google.maps.InfoWindow({
            content: html
        });

    google.maps.event.addListener(newmarker, 'mouseover', function() {
        this['infowindow'].open(map, this);
    });
}

you can simply use rstrip:

    for stuff in largestring:
        print(stuff.rstrip("\n")

>>> import re
>>> s = "start foo end"
>>> s = re.sub("foo", "replaced", s)
>>> s
'start replaced end'
>>> s = re.sub("(?<= )(.+)(?= )", lambda m: "can use a callable for the %s text too" % m.group(1), s)
>>> s

    a replacement string to be used.

1) Yes, a select with NOLOCK will complete faster than a normal select.

2) Yes, a select with NOLOCK will allow other queries against the effected table to complete faster than a normal select.

Why would this be?

NOLOCK typically (depending on your DB engine) means give me your data, and I don't care what state it is in, and don't bother holding it still while you read from it. It is all at once faster, less resource-intensive, and very very dangerous.

You should be warned to never do an update from or perform anything system critical, or where absolute correctness is required using data that originated from a NOLOCK read. It is absolutely possible that this data contains rows that were deleted during the query's run or that have been deleted in other sessions that have yet to be finalized. It is possible that this data includes rows that have been partially updated. It is possible that this data contains records that violate foreign key constraints. It is possible that this data excludes rows that have been added to the table but have yet to be committed.

You really have no way to know what the state of the data is.

If you're trying to get things like a Row Count or other summary data where some margin of error is acceptable, then NOLOCK is a good way to boost performance for these queries and avoid having them negatively impact database performance.

Always use the NOLOCK hint with great caution and treat any data it returns suspiciously.

Be careful with rebase. If you're sharing your develop branch with anybody, rebase can make a mess of things. Rebase is good only for your own local branches.

Rule of thumb, if you've pushed the branch to origin, don't use rebase. Instead, use merge.

Try removing the . before the .bmp (it isn't matching BMP as expected). As you can see from the error, the save_handler is upper-casing the format you provided and then looking for a match in SAVE. However the corresponding key in that object is BMP (instead of .BMP).

I don't know a great deal about PIL, but from some quick searching around it seems that it is a problem with the mode of the image. Changing the definition of j to:

j = Image.fromarray(b, mode='RGB')

Seemed to work for me (however note that I have very little knowledge of PIL, so I would suggest using @mmgp's solution as s/he clearly knows what they are doing :) ). For the types of mode, I used this page - hopefully one of the choices there will work for you.

I installed using the command:

./configure --prefix=/usr       \
            --enable-shared     \
            --with-system-expat \
            --with-system-ffi   \
            --enable-unicode=ucs4 &&

make

Now, as the root user:

make install &&
chmod -v 755 /usr/lib/libpython2.7.so.1.0

Then I tried to execute python and got the error:

/usr/local/bin/python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

Then, I logged out from root user and again tried to execute the Python and it worked successfully.

Javascript files are often cached by the browser for a lot longer than you might expect.

This can often result in unexpected behaviour when you release a new version of your JS file.

Therefore, it is common practice to add a QueryString parameter to the URL for the javascript file. That way, the browser caches the Javascript file with v=1. When you release a new version of your javascript file you change the url's to v=2 and the browser will be forced to download a new copy.

this is bad approach. you should work with assembly dll's, in which will do the same for you with better performance.

You can do like this:

#!/bin/bash

v="some string.rtf"

v2=${v::-4}

echo "$v --> $v2"

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

Here's an example geared toward watching input files that write no more than one line per second but usually a lot less. The goal is to append the last line (most recent write) to the specified output file. I've copied this from one of my projects and just deleted all the irrelevant lines. You'll have to fill in or change the missing symbols.

from PyQt5.QtCore import QFileSystemWatcher, QSettings, QThread
from ui_main_window import Ui_MainWindow   # Qt Creator gen'd 

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        QMainWindow.__init__(self, parent)
        Ui_MainWindow.__init__(self)
        self._fileWatcher = QFileSystemWatcher()
        self._fileWatcher.fileChanged.connect(self.fileChanged)

    def fileChanged(self, filepath):
        QThread.msleep(300)    # Reqd on some machines, give chance for write to complete
        # ^^ About to test this, may need more sophisticated solution
        with open(filepath) as file:
            lastLine = list(file)[-1]
        destPath = self._filemap[filepath]['dest file']
        with open(destPath, 'a') as out_file:               # a= append
            out_file.writelines([lastLine])

Of course, the encompassing QMainWindow class is not strictly required, ie. you can use QFileSystemWatcher alone.

The Distinct() is going to mess up the ordering, so you'll have to the sorting after that.

var uniqueColors = 
               (from dbo in database.MainTable 
                 where dbo.Property == true 
                 select dbo.Color.Name).Distinct().OrderBy(name=>name);

Without reading your code but just your scenario, I would solve by using localStorage. Here's an example, I'll use prompt() for short.

On page1:

window.onload = function() {
   var getInput = prompt("Hey type something here: ");
   localStorage.setItem("storageName",getInput);
}

On page2:

window.onload = alert(localStorage.getItem("storageName"));

You can also use cookies but localStorage allows much more spaces, and they aren't sent back to servers when you request pages.

No one mentioned Stream so far, so here it is:

if (Stream.of("Mon", "Tues", "Wed", "Thurs", "Fri").anyMatch(s -> newStr4.startsWith(s)))

It is possible :) Just change definition

def ldap_get ( base_dn, filter, scope=LDAP::LDAP_SCOPE_SUBTREE, attrs=nil )

to

def ldap_get ( base_dn, filter, *param_array, attrs=nil )
scope = param_array.first || LDAP::LDAP_SCOPE_SUBTREE

scope will be now in array on its first place. When you provide 3 arguments, then you will have assigned base_dn, filter and attrs and param_array will be [] When 4 and more arguments then param_array will be [argument1, or_more, and_more]

Downside is... it is unclear solution, really ugly. This is to answer that it is possible to ommit argument in the middle of function call in ruby :)

Another thing you have to do is to rewrite default value of scope.

MacVim is just Vim. Anything you are used to do in Vim will work exactly the same way in MacVim.

MacVim is more integrated in the whole OS than Vim in the Terminal or even GVim in Linux, it follows a lot of Mac OS X's conventions.

If you work mainly with GUI apps (YummyFTP + GitX + Charles, for example) you may prefer MacVim.

If you work mainly with CLI apps (ssh + svn + tcpdump, for example) you may prefer vim in the terminal.

Entering and leaving one realm (CLI) for the other (GUI) and vice-versa can be "expensive".

I use both MacVim and Vim depending on the task and the context: if I'm in CLI-land I'll just type vim filename and if I'm in GUI-land I'll just invoke Quicksilver and launch MacVim.

When I switched from TextMate I kind of liked the fact that MacVim supported almost all of the regular shortcuts Mac users are accustomed to. I added some of my own, mimiking TextMate but, since I was working in multiple environments I forced my self to learn the vim way. Now I use both MacVim and Vim almost exactly the same way. Using one or the other is just a question of context for me.

Also, like El Isra said, the default vim (CLI) in OS X is slightly outdated. You may install an up-to-date version via MacPorts or you can install MacVim and add an alias to your .profile:

alias vim='/path/to/MacVim.app/Contents/MacOS/Vim'

to have the same vim in MacVim and Terminal.app.

Another difference is that many great colorschemes out there work out of the box in MacVim but look terrible in the Terminal.app which only supports 8 colors (+ highlights) but you can use iTerm — which can be set up to support 256 colors — instead of Terminal.

So… basically my advice is to just use both.

EDIT: I didn't try it but the latest version of Terminal.app (in 10.7) is supposed to support 256 colors. I'm still on 10.6.x at work so I'll still use iTerm2 for a while.

EDIT: An even better way to use MacVim's CLI executable in your shell is to move the mvim script bundled with MacVim somewhere in your $PATH and use this command:

$ mvim -v

EDIT: Yes, Terminal.app now supports 256 colors. So if you don't need iTerm2's advanced features you can safely use the default terminal emulator.

function validateDays() {
    if (document.getElementById("option1").checked == true) {
        alert("You have selected Option 1");
    }
    else if (document.getElementById("option2").checked == true) {
        alert("You have selected Option 2");
    }
    else if (document.getElementById("option3").checked == true) {
        alert("You have selected Option 3");
    }
    else {
        // DO NOTHING
        }
    }

The following is a complete example based on JeeBee's post, using java enum's instead of using a custom method.

Note that in Java SE 7 and later you can use a String object in the switch statement's expression instead.

public class Main {

    /**
    * @param args the command line arguments
    */
    public static void main(String[] args) {

      String current = args[0];
      Days currentDay = Days.valueOf(current.toUpperCase());

      switch (currentDay) {
          case MONDAY:
          case TUESDAY:
          case WEDNESDAY:
              System.out.println("boring");
              break;
          case THURSDAY:
              System.out.println("getting better");
          case FRIDAY:
          case SATURDAY:
          case SUNDAY:
              System.out.println("much better");
              break;

      }
  }

  public enum Days {

    MONDAY,
    TUESDAY,
    WEDNESDAY,
    THURSDAY,
    FRIDAY,
    SATURDAY,
    SUNDAY
  }
}

You can also name columns directly in the cbind call, e.g.

cbind(date=c(0,1), high=c(2,3))

Output:

     date high
[1,]    0    2
[2,]    1    3

has_key was removed in Python 3. From the documentation:

• Removed dict.has_key() – use the in operator instead.

Here's an example:

if start not in graph:
    return None

I need a fast function that can check if a file is exist or not and PherricOxide's answer is almost what I need except it does not compare the performance of boost::filesystem::exists and open functions. From the benchmark results we can easily see that :

• Using stat function is the fastest way to check if a file is exist. Note that my results are consistent with that of PherricOxide's answer.

• The performance of boost::filesystem::exists function is very close to that of stat function and it is also portable. I would recommend this solution if boost libraries is accessible from your code.

You get the cursor position by calling GetCursorPos.

POINT p;
if (GetCursorPos(&p))
{
    //cursor position now in p.x and p.y
}

This returns the cursor position relative to screen coordinates. Call ScreenToClient to map to window coordinates.

if (ScreenToClient(hwnd, &p))
{
    //p.x and p.y are now relative to hwnd's client area
}

You hide and show the cursor with ShowCursor.

ShowCursor(FALSE);//hides the cursor
ShowCursor(TRUE);//shows it again

You must ensure that every call to hide the cursor is matched by one that shows it again.

This shell script also works for finding a file in a directory:

echo "enter file"

read -r a

if [ -s /home/trainee02/"$a" ]
then
    echo "yes. file is there."
else
    echo "sorry. file is not there."
fi

The save/load method mentioned above works for me. I am not sure how/if gc() defrags the memory but this seems to work.

# defrag memory 
save.image(file="temp.RData")
rm(list=ls())
load(file="temp.RData")

using jQuery 1.8 and above, should use the following:

var request = $.ajax({
    type: 'POST',
    url: 'mmm.php',
    data: { abc: "abcdefghijklmnopqrstuvwxyz" } })
    .done(function(data) { alert("success"+data.slice(0, 100)); })
    .fail(function() { alert("error"); })
    .always(function() { alert("complete"); });

check out the docs as @hitautodestruct stated.

I have done the following css approach:

<div class="holds-the-iframe"><iframe here></iframe></div>

.holds-the-iframe {
  background:url(../images/loader.gif) center center no-repeat;
}

Judging from the error message the value of i was the empty string when you executed it, not 0.

PipedInputStream and PipedOutputStream should only be used when you have multiple threads, as noted by the Javadoc.

Also, note that input streams and output streams do not wrap any thread interruptions with IOExceptions... So, you should consider incorporating an interruption policy to your code:

byte[] buffer = new byte[1024];
int len = in.read(buffer);
while (len != -1) {
    out.write(buffer, 0, len);
    len = in.read(buffer);
    if (Thread.interrupted()) {
        throw new InterruptedException();
    }
}

This would be an useful addition if you expect to use this API for copying large volumes of data, or data from streams that get stuck for an intolerably long time.

If your input always has a time zone of "zulu" ("Z" = UTC), then you can use DateTimeFormatter.ISO_INSTANT (implicitly):

final Instant parsed = Instant.parse(dateTime);

If time zone varies and has the form of "+01:00" or "+01:00:00" (when not "Z"), then you can use DateTimeFormatter.ISO_OFFSET_DATE_TIME:

DateTimeFormatter formatter = DateTimeFormatter.ISO_OFFSET_DATE_TIME;
final ZonedDateTime parsed = ZonedDateTime.parse(dateTime, formatter);

If neither is the case, you can construct a DateTimeFormatter in the same manner as DateTimeFormatter.ISO_OFFSET_DATE_TIME is constructed.

Your current pattern has several problems:

• not using strict mode (ResolverStyle.STRICT);
• using yyyy instead of uuuu (yyyy will not work in strict mode);
• using 12-hour hh instead of 24-hour HH;
• using only one digit S for fractional seconds, but input has three.

I'm using Ubuntu. I spent a whole morning fixing this, tried all different solutions, when I type go version, it's still there, really annoying... Finally this worked for me, hope this will help!

sudo apt-get remove golang-go
sudo apt-get remove --auto-remove golang-go

I would do this as

if isnumeric(ubound(a)) = False then msgbox "a is empty!"

Problem statement

Problem occurs when we want to import CommonJS module into ES6 module codebase.

Before these flags we had to import CommonJS modules with star (* as something) import:

// node_modules/moment/index.js
exports = moment

// index.ts file in our app
import * as moment from 'moment'
moment(); // not compliant with es6 module spec

// transpiled js (simplified):
const moment = require("moment");
moment();

We can see that * was somehow equivalent to exports variable. It worked fine, but it wasn't compliant with es6 modules spec. In spec, the namespace record in star import (moment in our case) can be only a plain object, not callable (moment() is not allowed).

Solution

With flag esModuleInterop we can import CommonJS modules in compliance with es6 modules spec. Now our import code looks like this:

// index.ts file in our app
import moment from 'moment'
moment(); // compliant with es6 module spec

// transpiled js with esModuleInterop (simplified):
const moment = __importDefault(require('moment'));
moment.default();

It works and it's perfectly valid with es6 modules spec, because moment is not namespace from star import, it's default import.

But how does it work? As you can see, because we did a default import, we called the default property on a moment object. But we didn't declare a default property on the exports object in the moment library. The key is the __importDefault function. It assigns module (exports) to the default property for CommonJS modules:

var __importDefault = (this && this.__importDefault) || function (mod) {
    return (mod && mod.__esModule) ? mod : { "default": mod };
};

As you can see, we import es6 modules as they are, but CommonJS modules are wrapped into an object with the default key. This makes it possible to import defaults on CommonJS modules.

__importStar does the similar job - it returns untouched esModules, but translates CommonJS modules into modules with a default property:

// index.ts file in our app
import * as moment from 'moment'

// transpiled js with esModuleInterop (simplified):
const moment = __importStar(require("moment"));
// note that "moment" is now uncallable - ts will report error!

var __importStar = (this && this.__importStar) || function (mod) {
    if (mod && mod.__esModule) return mod;
    var result = {};
    if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
    result["default"] = mod;
    return result;
};

Synthetic imports

And what about allowSyntheticDefaultImports - what is it for? Now the docs should be clear:

Allow default imports from modules with no default export. This does not affect code emit, just typechecking.

In moment typings we don't have specified default export, and we shouldn't have, because it's available only with flag esModuleInterop on. So allowSyntheticDefaultImports will not report an error if we want to import default from a third-party module which doesn't have a default export.

If you need to handle newlines in diferent systems you can simply use the PHP predefined constant PHP_EOL (http://php.net/manual/en/reserved.constants.php) and simply use explode to avoid the overhead of the regular expression engine.

How are you generating your data?

See how the output shows that your data is of 'object' type? the groupby operations specifically check whether each column is a numeric dtype first.

In [31]: data
Out[31]: 
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2557 entries, 2004-01-01 00:00:00 to 2010-12-31 00:00:00
Freq: <1 DateOffset>
Columns: 360 entries, -89.75 to 89.75
dtypes: object(360)

look ?

Did you initialize an empty DataFrame first and then filled it? If so that's probably why it changed with the new version as before 0.9 empty DataFrames were initialized to float type but now they are of object type. If so you can change the initialization to DataFrame(dtype=float).

You can also call frame.astype(float)

You can use jquery for this by utilizing addClass() method

CSS

 .defaultInput
    {
     width: 100px;
     height:25px;
     padding: 5px;
    }

.error
{
 border:1px solid red;
}

<input type="text" class="defaultInput"/>

Jquery Code

$(document).ready({
  $('.defaultInput').focus(function(){
       $(this).addClass('error');
  });
});

Update: You can remove that error class using

$('.defaultInput').removeClass('error');

It won't remove that default style. It will remove .error class only

In Java, once you have the reference of the button:

Button button = (Button) findviewById(R.id.button);

To enable/disable the button, you can use either:

button.setEnabled(false);
button.setEnabled(true);

Or:

button.setClickable(false);
button.setClickable(true);

Since you want to disable the button from the beginning, you can use button.setEnabled(false); in the onCreate method. Otherwise, from XML, you can directly use:

android:clickable = "false"

So:

<Button
        android:id="@+id/button"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="@string/button_text"
        android:clickable = "false" />

Use "\n" instead of '\n'

There is a math function modf() that will break this up as well.

import math

print("math.modf(3.14159) : ", math.modf(3.14159))

will output a tuple: math.modf(3.14159) : (0.14159, 3.0)

This is useful if you want to keep both the whole part and decimal for reference like:

decimal, whole = math.modf(3.14159)

As it has already been mentioned in che's answer about adding the remote part, which I believe you are still missing.

Regarding your edit for adding remote on your local USB drive. First of all you must have a 'bare repository' if you want your repository to be a shared repository i.e. to be able to push/pull/fetch/merge etc..

To create a bare/shared repository, go to your desired location. In your case:

$ cd /Volumes/500gb/   
$ git init --bare myproject.git

See here for more info on creating bare repository

Once you have a bare repository set up in your desired location you can now add it to your working copy as a remote.

$ git remote add origin /Volumes/500gb/myproject.git

And now you can push your changes to your repository

$ git push origin master

I had the same issue. I installed gitx instead.

You can install gitx from here.

http://rowanj.github.io/gitx/

Download the package and install it. After that open the gitk from spotlight search, goto the top left corner. Click on GitX and enable the terminal usage.

Goto your repo and simply type:

$ gitx --all

It will open the Gui.

We can find the proxy documentation for Angular-CLI over here:

https://github.com/angular/angular-cli/blob/master/docs/documentation/stories/proxy.md

After setting up a file called proxy.conf.json in your root folder, edit your package.json to include the proxy config on ng start. After adding "start": "ng serve --proxy-config proxy.conf.json" to your scripts, run npm start and not ng serve, because that will ignore the flag setup in your package.json.

current version of angular-cli: 1.1.0

Wrapper class is a wrapper around a primitive data type. It represents primitive data types in their corresponding class instances e.g. a boolean data type can be represented as a Boolean class instance. All of the primitive wrapper classes in Java are immutable i.e. once assigned a value to a wrapper class instance cannot be changed further.

Answering the additional question:

my following test code for typeid does not output the correct type name. what's wrong?

There isn't anything wrong. What you see is the string representation of the type name. The standard C++ doesn't force compilers to emit the exact name of the class, it is just up to the implementer(compiler vendor) to decide what is suitable. In short, the names are up to the compiler.

These are two different tools. typeof returns the type of an expression, but it is not standard. In C++0x there is something called decltype which does the same job AFAIK.

decltype(0xdeedbeef) number = 0; // number is of type int!
decltype(someArray[0]) element = someArray[0];

Whereas typeid is used with polymorphic types. For example, lets say that cat derives animal:

animal* a = new cat; // animal has to have at least one virtual function
...
if( typeid(*a) == typeid(cat) )
{
    // the object is of type cat! but the pointer is base pointer.
}

The Google Play Store doesn't provide this data, so the sites must just be scraping it.

extern std::pair<std::string_view, Base*(*)()> const factories[2];

decltype(factories) factories{
  {"blah", []() -> Base*{return new Blah;}},
  {"foo", []() -> Base*{return new Foo;}}
};

gcc 7.4.0 can not compile codes as below:

#include <stdio.h>
const char * const str1 = "str1";
const char * str2 = str1;
int main() {
    printf("%s - %s\n", str1, str2);
    return 0;
}

constchar.c:3:21: error: initializer element is not constant const char * str2 = str1;

In fact, a "const char *" string is not a compile-time constant, so it can't be an initializer. But a "const char * const" string is a compile-time constant, it should be able to be an initializer. I think this is a small drawback of CLang.

A function name is of course a compile-time constant.So this code works:

void func(void)
{
    printf("func\n");
}
typedef void (*func_type)(void);
func_type f = func;
int main() {
    f();
    return 0;
}

you can also use the Activity Monitor to stop the py process

I had similar problem and this seem to solve the problem. You just need to initialize the $res object to a class . Suppose here the class name is test.

class test
{
   //You can keep the class empty or declare your success variable here
}
$res = new test();
$res->success = false;

The 100% working solution

public static function rmdir_recursive($directory, $delete_parent = null)
  {
    $files = glob($directory . '/{,.}[!.,!..]*',GLOB_MARK|GLOB_BRACE);
    foreach ($files as $file) {
      if (is_dir($file)) {
        self::rmdir_recursive($file, 1);
      } else {
        unlink($file);
      }
    }
    if ($delete_parent) {
      rmdir($directory);
    }
  }

You can use this for color without alpha:

String hexColor = String.format("#%06X", (0xFFFFFF & intColor));

or this with alpha:

String hexColor = String.format("#%08X", (0xFFFFFFFF & intColor));

So let's say you have a local branch foo, a remote called origin and a remote branch origin/master.

To push the contents of foo to origin/master, you first need to set its upstream:

git checkout foo
git branch -u origin/master

Then you can push to this branch using:

git push origin HEAD:master

In the last command you can add --force to replace the entire history of origin/master with that of foo.

The best method would be using a javascript -only function:

var myArr = Array.prototype.slice.call(myObj, 0);

i guess your could use the --name-only flag. something like:

git log 73167b96 --pretty="format:" --name-only

i personally use git show for viewing files changed in a commit

git show --pretty="format:" --name-only 73167b96

(73167b96 could be any commit/tag name)

Try This it works well.

Container(
  height: 220.0,
  width: double.infinity,
  decoration: BoxDecoration(
    borderRadius: new BorderRadius.only(
      topLeft: Radius.circular(10),
       topRight: Radius.circular(10),
    ),
    image: DecorationImage(
      fit: BoxFit.fill,
      image: NetworkImage(
        photoUrl,
      ),
     ),
   ),
);

In my case, I knew the child component would always be present, but wanted to alter the state prior to the child initializing to save work.

I choose to test for the child until it appeared and make changes immediately, which saved me a change cycle on the child component.

export class GroupResultsReportComponent implements OnInit {

    @ViewChild(ChildComponent) childComp: ChildComponent;

    ngOnInit(): void {
        this.WhenReady(() => this.childComp, () => { this.childComp.showBar = true; });
    }

    /**
     * Executes the work, once the test returns truthy
     * @param test a function that will return truthy once the work function is able to execute 
     * @param work a function that will execute after the test function returns truthy
     */
    private WhenReady(test: Function, work: Function) {
        if (test()) work();
        else setTimeout(this.WhenReady.bind(window, test, work));
    }
}

Alertnatively, you could add a max number of attempts or add a few ms delay to the setTimeout. setTimeout effectively throws the function to the bottom of the list of pending operations.

To disable a submit button, you just need to add a disabled attribute to the submit button.

$("#btnSubmit").attr("disabled", true);

To enable a disabled button, set the disabled attribute to false, or remove the disabled attribute.

$('#btnSubmit').attr("disabled", false);

or

$('#btnSubmit').removeAttr("disabled");

In our case we just want to reload the page in webview and for some reasons we couldn't find out why! We try almost every solution that has been on the web, but stuck with no reloading using location.reload() or alternative solutions like window.location.reload(), location.reload(true), ...!

Here is our simple solution :

Just use a < a > tag with the empty "href" attribution value like this :

< a href="" ...>Click Me</a>

(in some cases you have to use "return true" on click of the target to trigger reload)

For more information check out this question : Is an empty href valid?

hyperlink1.NavigateUrl = "#"; or
hyperlink1.attributes["href"] = "#"; or
<asp:HyperLink NavigateUrl="#" runat="server" />

None of that stuff worked. Here's a much simpler way .. the label str is the pointer to what IS an array...

String str = String(yourNumber, DEC); // Obviously .. get your int or byte into the string

str = str + '\r' + '\n'; // Add the required carriage return, optional line feed

byte str_len = str.length();

// Get the length of the whole lot .. C will kindly
// place a null at the end of the string which makes
// it by default an array[].
// The [0] element is the highest digit... so we
// have a separate place counter for the array...

byte arrayPointer = 0;

while (str_len)
{
    // I was outputting the digits to the TX buffer

    if ((UCSR0A & (1<<UDRE0))) // Is the TX buffer empty?
    {
        UDR0 = str[arrayPointer];
        --str_len;
        ++arrayPointer;
    }
}

Without rooting: If you can't root your phone, use the run-as <package> command to be able to access data of your application.

Example:

$ adb exec-out run-as com.yourcompany.app ls -R /data/data/com.yourcompany.app/

exec-out executes the command without starting a shell and mangling the output.

I had the same issue and tried most of the solutions mentioned above and they did not fix it.. At then end, I went to my .csproj file and viewed it in the text editor, I found that my xml file that I put in the /Drawable was not set to be AndroidResouces it was just of type Content.

Changing that to be of type AndroidResouces fixed the issue for me.

You can use an index and a while loop instead of a for loop if you want the loop to also loop over the elements that is added to the list during the loop:

i = 0
while i < len(myarr):
    a = myarr[i];
    i = i + 1;
    if somecond(a):
        myarr.append(newObj())

This is an old question, but comes out high in my Google search for 'perl merge hashes' - and yet it does not mention the very helpful CPAN module Hash::Merge

At the top right corner of the problems window (next to minimize) there is a small arrow-icon. Click it and select "Configure filters". There is a severity filter that might have been activated.

In Typescript 1.5 and later, you can use for..of as opposed to for..in

var numbers = [1, 2, 3];

for (var number of numbers) {
    console.log(number);
}

A modification to GUS's example:

$(document).ready(function() {
    var tmpImg = new Image() ;
    tmpImg.onload = function() {
        // Run onload code.
    } ;

tmpImg.src = $('#img').attr('src');
})

Set the source before and after the onload.

The return type of a lambda (in C++11) can be deduced, but only when there is exactly one statement, and that statement is a return statement that returns an expression (an initializer list is not an expression, for example). If you have a multi-statement lambda, then the return type is assumed to be void.

Therefore, you should do this:

  remove_if(rawLines.begin(), rawLines.end(), [&expression, &start, &end, &what, &flags](const string& line) -> bool
  {
    start = line.begin();
    end = line.end();
    bool temp = boost::regex_search(start, end, what, expression, flags);
    return temp;
  })

But really, your second expression is a lot more readable.

Are you looking for exit?

Mockito matchers are static methods and calls to those methods, which stand in for arguments during calls to when and verify.

Hamcrest matchers (archived version) (or Hamcrest-style matchers) are stateless, general-purpose object instances that implement Matcher<T> and expose a method matches(T) that returns true if the object matches the Matcher's criteria. They are intended to be free of side effects, and are generally used in assertions such as the one below.

/* Mockito */  verify(foo).setPowerLevel(gt(9000));
/* Hamcrest */ assertThat(foo.getPowerLevel(), is(greaterThan(9000)));

Mockito matchers exist, separate from Hamcrest-style matchers, so that descriptions of matching expressions fit directly into method invocations: Mockito matchers return T where Hamcrest matcher methods return Matcher objects (of type Matcher<T>).

Mockito matchers are invoked through static methods such as eq, any, gt, and startsWith on org.mockito.Matchers and org.mockito.AdditionalMatchers. There are also adapters, which have changed across Mockito versions:

• For Mockito 1.x, Matchers featured some calls (such as intThat or argThat) are Mockito matchers that directly accept Hamcrest matchers as parameters. ArgumentMatcher<T> extended org.hamcrest.Matcher<T>, which was used in the internal Hamcrest representation and was a Hamcrest matcher base class instead of any sort of Mockito matcher.
• For Mockito 2.0+, Mockito no longer has a direct dependency on Hamcrest. Matchers calls phrased as intThat or argThat wrap ArgumentMatcher<T> objects that no longer implement org.hamcrest.Matcher<T> but are used in similar ways. Hamcrest adapters such as argThat and intThat are still available, but have moved to MockitoHamcrest instead.

Regardless of whether the matchers are Hamcrest or simply Hamcrest-style, they can be adapted like so:

/* Mockito matcher intThat adapting Hamcrest-style matcher is(greaterThan(...)) */
verify(foo).setPowerLevel(intThat(is(greaterThan(9000))));

In the above statement: foo.setPowerLevel is a method that accepts an int. is(greaterThan(9000)) returns a Matcher<Integer>, which wouldn't work as a setPowerLevel argument. The Mockito matcher intThat wraps that Hamcrest-style Matcher and returns an int so it can appear as an argument; Mockito matchers like gt(9000) would wrap that entire expression into a single call, as in the first line of example code.

What matchers do/return

when(foo.quux(3, 5)).thenReturn(true);

When not using argument matchers, Mockito records your argument values and compares them with their equals methods.

when(foo.quux(eq(3), eq(5))).thenReturn(true);    // same as above
when(foo.quux(anyInt(), gt(5))).thenReturn(true); // this one's different

When you call a matcher like any or gt (greater than), Mockito stores a matcher object that causes Mockito to skip that equality check and apply your match of choice. In the case of argumentCaptor.capture() it stores a matcher that saves its argument instead for later inspection.

Matchers return dummy values such as zero, empty collections, or null. Mockito tries to return a safe, appropriate dummy value, like 0 for anyInt() or any(Integer.class) or an empty List<String> for anyListOf(String.class). Because of type erasure, though, Mockito lacks type information to return any value but null for any() or argThat(...), which can cause a NullPointerException if trying to "auto-unbox" a null primitive value.

Matchers like eq and gt take parameter values; ideally, these values should be computed before the stubbing/verification starts. Calling a mock in the middle of mocking another call can interfere with stubbing.

Matcher methods can't be used as return values; there is no way to phrase thenReturn(anyInt()) or thenReturn(any(Foo.class)) in Mockito, for instance. Mockito needs to know exactly which instance to return in stubbing calls, and will not choose an arbitrary return value for you.

Implementation details

Matchers are stored (as Hamcrest-style object matchers) in a stack contained in a class called ArgumentMatcherStorage. MockitoCore and Matchers each own a ThreadSafeMockingProgress instance, which statically contains a ThreadLocal holding MockingProgress instances. It's this MockingProgressImpl that holds a concrete ArgumentMatcherStorageImpl. Consequently, mock and matcher state is static but thread-scoped consistently between the Mockito and Matchers classes.

Most matcher calls only add to this stack, with an exception for matchers like and, or, and not. This perfectly corresponds to (and relies on) the evaluation order of Java, which evaluates arguments left-to-right before invoking a method:

when(foo.quux(anyInt(), and(gt(10), lt(20)))).thenReturn(true);
[6]      [5]  [1]       [4] [2]     [3]

This will:

1. Add anyInt() to the stack.
2. Add gt(10) to the stack.
3. Add lt(20) to the stack.
4. Remove gt(10) and lt(20) and add and(gt(10), lt(20)).
5. Call foo.quux(0, 0), which (unless otherwise stubbed) returns the default value false. Internally Mockito marks quux(int, int) as the most recent call.
6. Call when(false), which discards its argument and prepares to stub method quux(int, int) identified in 5. The only two valid states are with stack length 0 (equality) or 2 (matchers), and there are two matchers on the stack (steps 1 and 4), so Mockito stubs the method with an any() matcher for its first argument and and(gt(10), lt(20)) for its second argument and clears the stack.

This demonstrates a few rules:

• Mockito can't tell the difference between quux(anyInt(), 0) and quux(0, anyInt()). They both look like a call to quux(0, 0) with one int matcher on the stack. Consequently, if you use one matcher, you have to match all arguments.

• Call order isn't just important, it's what makes this all work. Extracting matchers to variables generally doesn't work, because it usually changes the call order. Extracting matchers to methods, however, works great.

  int between10And20 = and(gt(10), lt(20));
  /* BAD */ when(foo.quux(anyInt(), between10And20)).thenReturn(true);
  // Mockito sees the stack as the opposite: and(gt(10), lt(20)), anyInt().
  
  public static int anyIntBetween10And20() { return and(gt(10), lt(20)); }
  /* OK */  when(foo.quux(anyInt(), anyIntBetween10And20())).thenReturn(true);
  // The helper method calls the matcher methods in the right order.
  

• The stack changes often enough that Mockito can't police it very carefully. It can only check the stack when you interact with Mockito or a mock, and has to accept matchers without knowing whether they're used immediately or abandoned accidentally. In theory, the stack should always be empty outside of a call to when or verify, but Mockito can't check that automatically. You can check manually with Mockito.validateMockitoUsage().

• In a call to when, Mockito actually calls the method in question, which will throw an exception if you've stubbed the method to throw an exception (or require non-zero or non-null values). doReturn and doAnswer (etc) do not invoke the actual method and are often a useful alternative.

• If you had called a mock method in the middle of stubbing (e.g. to calculate an answer for an eq matcher), Mockito would check the stack length against that call instead, and likely fail.

• If you try to do something bad, like stubbing/verifying a final method, Mockito will call the real method and also leave extra matchers on the stack. The final method call may not throw an exception, but you may get an InvalidUseOfMatchersException from the stray matchers when you next interact with a mock.

Common problems

• InvalidUseOfMatchersException:

  • Check that every single argument has exactly one matcher call, if you use matchers at all, and that you haven't used a matcher outside of a when or verify call. Matchers should never be used as stubbed return values or fields/variables.

  • Check that you're not calling a mock as a part of providing a matcher argument.

  • Check that you're not trying to stub/verify a final method with a matcher. It's a great way to leave a matcher on the stack, and unless your final method throws an exception, this might be the only time you realize the method you're mocking is final.

• NullPointerException with primitive arguments: (Integer) any() returns null while any(Integer.class) returns 0; this can cause a NullPointerException if you're expecting an int instead of an Integer. In any case, prefer anyInt(), which will return zero and also skip the auto-boxing step.

• NullPointerException or other exceptions: Calls to when(foo.bar(any())).thenReturn(baz) will actually call foo.bar(null), which you might have stubbed to throw an exception when receiving a null argument. Switching to doReturn(baz).when(foo).bar(any()) skips the stubbed behavior.

General troubleshooting

• Use MockitoJUnitRunner, or explicitly call validateMockitoUsage in your tearDown or @After method (which the runner would do for you automatically). This will help determine whether you've misused matchers.

• For debugging purposes, add calls to validateMockitoUsage in your code directly. This will throw if you have anything on the stack, which is a good warning of a bad symptom.

Alright, if don't need your divider color to be changed just apply alpha to the divider decorations.

Example for GridLayoutManager with transparency:

DividerItemDecoration horizontalDividerItemDecoration = new DividerItemDecoration(WishListActivity.this,
                DividerItemDecoration.HORIZONTAL);
        horizontalDividerItemDecoration.getDrawable().setAlpha(50);
        DividerItemDecoration verticalDividerItemDecoration = new DividerItemDecoration(WishListActivity.this,
                DividerItemDecoration.VERTICAL);
        verticalDividerItemDecoration.getDrawable().setAlpha(50);
        my_recycler.addItemDecoration(horizontalDividerItemDecoration);
        my_recycler.addItemDecoration(verticalDividerItemDecoration);

You can still change the color of dividers by just setting color filters to it.

Example for GridLayoutManager by setting tint:

DividerItemDecoration horizontalDividerItemDecoration = new DividerItemDecoration(WishListActivity.this,
                DividerItemDecoration.HORIZONTAL);
        horizontalDividerItemDecoration.getDrawable().setTint(getResources().getColor(R.color.colorAccent));
        DividerItemDecoration verticalDividerItemDecoration = new DividerItemDecoration(WishListActivity.this,
                DividerItemDecoration.VERTICAL);
        verticalDividerItemDecoration.getDrawable().setAlpha(50);
        my_recycler.addItemDecoration(horizontalDividerItemDecoration);
        my_recycler.addItemDecoration(verticalDividerItemDecoration);

Additionally you can also try setting color filter,

 horizontalDividerItemDecoration.getDrawable().setColorFilter(colorFilter);

This worked for me:

    input[type='number'] {
    appearance: none;
}

Solved in Firefox, Safari, Chrome. Also, -moz-appearance: textfield; is not supported anymore (https://developer.mozilla.org/en-US/docs/Web/CSS/appearance)

<input type="text" name="name" id="event" onkeydown="return alphaOnly(event);"   required />


function alphaOnly(event) {
  var key = event.keyCode;`enter code here`
  return ((key >= 65 && key <= 90) || key == 8);
};

It seems that your Java code is using IPv6 instead of IPv4. Please try to use 127.0.0.1 instead of localhost. Ex.: Your connection string should be

jdbc:mysql://127.0.0.1:3306/expeditor?zeroDateTimeBehavior=convertToNull&user=root&password=onelife

P.S.: Please update the URL connection string.

I had these SQL behavior settings enabled on options query execution: ANSI SET IMPLICIT_TRANSACTIONS checked. On execution of your query e.g create, alter table or stored procedure, you have to COMMIT it.

Just type COMMIT and execute it F5

If you want to find the folder in a platform independent way, you should query the registry key:

Try the following steps:

1) Open project.json file and Remove all Microsoft.EntityFrameworkCore.Tools references from dependencies and tools sections.

2) Close Package Manager Console (PMC) and restart Visual Studio

3) Add under dependencies section:

 "Microsoft.EntityFrameworkCore.Tools": {
  "version": "1.0.0-preview2-final",
  "type": "build"
 }

4) Add under tools section

"Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final"

5) Restart again Visual Studio 2015

6) Open the PMC and type

Add-Migration $Your_First_Migration_Name$

This happen because the PMC recognize the tools when Visual Studio is starting.
