It worth mentioning that if you intend to package your application with PyInstaller and wise to avoid supporting that feature by yourself, you can pass the --uac-admin or --uac-uiaccess argument in order to request UAC elevation on start.

My two cents on this topic, trying to provide a generic, double conversion method:

private static double ParseDouble(object value)
{
    double result;

    string doubleAsString = value.ToString();
    IEnumerable<char> doubleAsCharList = doubleAsString.ToList();

    if (doubleAsCharList.Where(ch => ch == '.' || ch == ',').Count() <= 1)
    {
        double.TryParse(doubleAsString.Replace(',', '.'),
            System.Globalization.NumberStyles.Any,
            CultureInfo.InvariantCulture,
            out result);
    }
    else
    {
        if (doubleAsCharList.Where(ch => ch == '.').Count() <= 1
            && doubleAsCharList.Where(ch => ch == ',').Count() > 1)
        {
            double.TryParse(doubleAsString.Replace(",", string.Empty),
                System.Globalization.NumberStyles.Any,
                CultureInfo.InvariantCulture,
                out result);
        }
        else if (doubleAsCharList.Where(ch => ch == ',').Count() <= 1
            && doubleAsCharList.Where(ch => ch == '.').Count() > 1)
        {
            double.TryParse(doubleAsString.Replace(".", string.Empty).Replace(',', '.'),
                System.Globalization.NumberStyles.Any,
                CultureInfo.InvariantCulture,
                out result);
        }
        else
        {
            throw new ParsingException($"Error parsing {doubleAsString} as double, try removing thousand separators (if any)");
        }
    }

    return result;
}

Works as expected with:

• 1.1
• 1,1
• 1,000,000,000
• 1.000.000.000
• 1,000,000,000.99
• 1.000.000.000,99
• 5,000,111.3
• 5.000.111,3
• 0.99,000,111,88
• 0,99.000.111.88

No default conversion is implemented, so it would fail trying to parse 1.3,14, 1,3.14 or similar cases.

I came across this question when I had to deal with a particular case: fully updating of content in a "leaf" table (no FKs pointing to it). This involved removing all rows and putting new rows information and it should be done transactionally (I do not want to end up with an empty table, if inserts fails for whatever reason).

I have tried the public static void Clear<T>(this DbSet<T> dbSet) approach, but new rows are not inserted. Another disadvante is that the whole process is slow, as rows are deleted one by one.

So, I have switched to TRUNCATE approach, since it is much faster and it is also ROLLBACKable. It also resets the identity.

Example using repository pattern:

public class Repository<T> : IRepository<T> where T : class, new()
{
    private readonly IEfDbContext _context;

    public void BulkInsert(IEnumerable<T> entities)
    {
        _context.BulkInsert(entities);
    }

    public void Truncate()
    {
        _context.Database.ExecuteSqlCommand($"TRUNCATE TABLE {typeof(T).Name}");
    }
 }

 // usage 
 DataAccess.TheRepository.Truncate();
 var toAddBulk = new List<EnvironmentXImportingSystem>();

 // fill toAddBulk from source system
 // ...

 DataAccess.TheRepository.BulkInsert(toAddBulk);
 DataAccess.SaveChanges();

Of course, as already mentioned, this solution cannot be used by tables referenced by foreign keys (TRUNCATE fails).

The static factory method pattern is a way to encapsulate object creation. Without a factory method, you would simply call the class's constructor directly: Foo x = new Foo(). With this pattern, you would instead call the factory method: Foo x = Foo.create(). The constructors are marked private, so they cannot be called except from inside the class, and the factory method is marked as static so that it can be called without first having an object.

There are a few advantages to this pattern. One is that the factory can choose from many subclasses (or implementers of an interface) and return that. This way the caller can specify the behavior desired via parameters, without having to know or understand a potentially complex class hierarchy.

Another advantage is, as Matthew and James have pointed out, controlling access to a limited resource such as connections. This a way to implement pools of reusable objects - instead of building, using, and tearing down an object, if the construction and destruction are expensive processes it might make more sense to build them once and recycle them. The factory method can return an existing, unused instantiated object if it has one, or construct one if the object count is below some lower threshold, or throw an exception or return null if it's above the upper threshold.

As per the article on Wikipedia, multiple factory methods also allow different interpretations of similar argument types. Normally the constructor has the same name as the class, which means that you can only have one constructor with a given signature. Factories are not so constrained, which means you can have two different methods that accept the same argument types:

Coordinate c = Coordinate.createFromCartesian(double x, double y)

and

Coordinate c = Coordinate.createFromPolar(double distance, double angle)

This can also be used to improve readability, as Rasmus notes.

I recommend using PDFObject for PDF plugin detection.

This will only allow you to display alternate content if the user's browser isn't capable of displaying the PDF directly though. For example, the PDF will display fine in Chrome for most users, but they will need a plugin like Adobe Reader installed if they're using Firefox or Internet Explorer.

At least PDFObject will allow you to display a message with a link to download Adobe Reader and/or the PDF file itself if their browser doesn't already have a PDF plugin installed.

As Hogan notes above, use an AND instead of &. See this tutorial for more info.

This error arise from the fact that you are trying to define an object of shape (0,) as an object of shape (2,). If you append what you want without forcing it to be equal to result[0] there is no any issue:

b = np.append([result[0]], [1,2])

But when you define result[0] = b you are equating objects of different shapes, and you can not do this. What are you trying to do?

For scientific python users, here is a simple solution using Pandas:

import pandas as pd
stats = {'a': 1000, 'b': 3000, 'c': 100}
series = pd.Series(stats)
series.idxmax()

>>> b

To print keys on one line as csv:

echo '{"b":"2","a":"1"}' | jq -r 'keys | [ .[] | tostring ] | @csv'

Output:

"a","b"

For csv completeness ... to print values on one line as csv:

echo '{"b":"2","a":"1"}' | jq -rS . | jq -r '. | [ .[] | tostring ] | @csv'

Output:

"1","2"

The class BooleanUtils supportes the negation of a boolean. You find this class in commons-lang:commons-lang

BooleanUtils.negate(theBoolean)

To answer your question about downloading files by hand, you can extract the relevant URLs from the SDK Manager's repository manifest:

https://dl-ssl.google.com/android/repository/repository.xml

simply snapshot means it is the version which is not stable one.

when version includes snapshot like 1.0.0 -SNAPSHOT means it is not stable version and look for remote repository to resolve dependencies

By adding fragment_tran.addToBackStack(null) on last fragment, I am able to do come back on last fragment.

adding new fragment:

view.findViewById(R.id.changepass).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
            transaction.replace(R.id.container, new ChangePassword());
            transaction.addToBackStack(null);
            transaction.commit();
        }
    });

I performed a full-on cop-out and wrote a class which creates a batch file and then calls sftp via a system call. Not the nicest (or fastest) way of doing it but it works for what I need and it didn't require any installation of extra libraries or extensions in PHP.

Could be the way to go if you don't want to use the ssh2 extensions

Objective-C is not Java. In Objective-C exceptions are what they are called. Exceptions! Don’t use them for error handling. It’s not their proposal. Just check the length of the string before using characterAtIndex and everything is fine....

In this code you are not comparing string values, you are comparing pointer values. If you want to compare string values you need to use a string comparison function such as strcmp.

if ( 0 == strcmp(var1, "dev")) {
  ..
}

with open(player_name, 'r') as myfile:
 data=myfile.readline()
 list=data.split(" ")
 word=list[0]

This code will help you to read the first line and then using the list and split option you can convert the first line word separated by space to be stored in a list.

Than you can easily access any word, or even store it in a string.

You can also do the same thing with using a for loop.

To H2oRider -- does your application access the Oracle dll in the GAC? What I recommend you do is this: Add the dll to your project and set the build action to "content" and set "copy to output directory" to "copy always".

Then delete your reference(s) to the dll in the GAC. Re-add the reference, but this time drill down to the one you just added to your project.

Now publish it. The application will look for the dll locally, and the dll is included in the deployment so it will find it.

If this doesn't work, then it might be that you can not use that dll if included locally rather than in the GAC. This is true of some assemblies, like the Office PIAs. In that case, the only way to deploy it is to wrap it in a setup & deployment package and use the Bootstrapper Manifest Generator to turn it into a prerequisite you can publish with ClickOnce deployment.

Before you call setContentView(), call setTheme(android.R.style...) and just replace the ... with the theme that you want(Theme, Theme_NoTitleBar, etc.).

Or if your theme is a custom theme, then replace the entire thing, so you get setTheme(yourThemesResouceId)

You need the data to be in "tall" format instead of "wide" for ggplot2. "wide" means having an observation per row with each variable as a different column (like you have now). You need to convert it to a "tall" format where you have a column that tells you the name of the variable and another column that tells you the value of the variable. The process of passing from wide to tall is usually called "melting". You can use tidyr::gather to melt your data frame:

library(ggplot2)
library(tidyr)

test_data <-
  data.frame(
    var0 = 100 + c(0, cumsum(runif(49, -20, 20))),
    var1 = 150 + c(0, cumsum(runif(49, -10, 10))),
    date = seq(as.Date("2002-01-01"), by="1 month", length.out=100)
  )
test_data %>%
    gather(key,value, var0, var1) %>%
    ggplot(aes(x=date, y=value, colour=key)) +
    geom_line()

Just to be clear the data that ggplot is consuming after piping it via gather looks like this:

date        key     value
2002-01-01  var0    100.00000
2002-02-01  var0    115.16388 
...
2007-11-01  var1    114.86302
2007-12-01  var1    119.30996

Maybe off-topic, but R features two nice, fast and empty-aware functions for reducing logical vectors -- any and all:

if(any(x=='dolphin')) stop("Told you, no mammals!")

Another option is to add another tag with flex: auto style in between your tags that you want to fill in the remaining space.

https://jsfiddle.net/tsey5qu4/

The HTML:

<div class="parent">
  <div class="left">Left</div>
  <div class="fill-remaining-space"></div>
  <div class="right">Right</div>
</div>

The CSS:

.fill-remaining-space {
  flex: auto;
}

This is equivalent to flex: 1 1 auto, which absorbs any extra space along the main axis.

bsondump collection.bson > collection.json

and then

mongoimport -d <dbname> -c <collection> < collection.json

Create custom directive

masterApp.directive('ngRenderCallback', function() {
    return {
        restrict: "A",
        link: function ($scope, element, attrs) {
            setTimeout(function(){ 
                $scope[attrs.ngEl] = element[0];
                $scope.$eval(attrs.ngRenderCallback);               
            }, 30);
        }
    }
});

code for html template

<div ng-render-callback="fnRenderCarousel('carouselA')" ng-el="carouselA"></div>

$scope.fnRenderCarousel = function(elName){
    $($scope[elName]).carousel();
}

The CAST() function does not support the "official" data type "INT" in MySQL, it's not in the list of supported types. With MySQL, "SIGNED" (or "UNSIGNED") could be used instead:

CAST(columnName AS SIGNED)

However, this seems to be MySQL-specific (not standardized), so it may not work with other databases. At least this document (Second Informal Review Draft) ISO/IEC 9075:1992, Database does not list "SIGNED"/"UNSIGNED" in section 4.4 Numbers.

But DECIMAL is both standardized and supported by MySQL, so the following should work for MySQL (tested) and other databases:

CAST(columnName AS DECIMAL(0))

According to the MySQL docs:

If the scale is 0, DECIMAL values contain no decimal point or fractional part.

This is a good and a tricky question. The topic of URI design is at the same time the most prominent part of a REST API and, therefore, a potentially long-term commitment towards the users of that API.

Since evolution of an application and, to a lesser extent, its API is a fact of life and that it's even similar to the evolution of a seemingly complex product like a programming language, the URI design should have less natural constraints and it should be preserved over time. The longer the application's and API's lifespan, the greater the commitment to the users of the application and API.

On the other hand, another fact of life is that it is hard to foresee all the resources and their aspects that would be consumed through the API. Luckily, it is not necessary to design the entire API which will be used until Apocalypse. It is sufficient to correctly define all the resource end-points and the addressing scheme of every resource and resource instance.

Over time you may need to add new resources and new attributes to each particular resource, but the method that API users follow to access a particular resources should not change once a resource addressing scheme becomes public and therefore final.

This method applies to HTTP verb semantics (e.g. PUT should always update/replace) and HTTP status codes that are supported in earlier API versions (they should continue to work so that API clients that have worked without human intervention should be able to continue to work like that).

Furthermore, since embedding of API version into the URI would disrupt the concept of hypermedia as the engine of application state (stated in Roy T. Fieldings PhD dissertation) by having a resource address/URI that would change over time, I would conclude that API versions should not be kept in resource URIs for a long time meaning that resource URIs that API users can depend on should be permalinks.

Sure, it is possible to embed API version in base URI but only for reasonable and restricted uses like debugging a API client that works with the the new API version. Such versioned APIs should be time-limited and available to limited groups of API users (like during closed betas) only. Otherwise, you commit yourself where you shouldn't.

A couple of thoughts regarding maintenance of API versions that have expiration date on them. All programming platforms/languages commonly used to implement web services (Java, .NET, PHP, Perl, Rails, etc.) allow easy binding of web service end-point(s) to a base URI. This way it's easy to gather and keep a collection of files/classes/methods separate across different API versions.

From the API users POV, it's also easier to work with and bind to a particular API version when it's this obvious but only for limited time, i.e. during development.

From the API maintainer's POV, it's easier to maintain different API versions in parallel by using source control systems that predominantly work on files as the smallest unit of (source code) versioning.

However, with API versions clearly visible in URI there's a caveat: one might also object this approach since API history becomes visible/aparent in the URI design and therefore is prone to changes over time which goes against the guidelines of REST. I agree!

The way to go around this reasonable objection, is to implement the latest API version under versionless API base URI. In this case, API client developers can choose to either:

• develop against the latest one (committing themselves to maintain the application protecting it from eventual API changes that might break their badly designed API client).

• bind to a specific version of the API (which becomes apparent) but only for a limited time

For example, if API v3.0 is the latest API version, the following two should be aliases (i.e. behave identically to all API requests):

http://shonzilla/api/customers/1234
http://shonzilla/api/v3.0/customers/1234
http://shonzilla/api/v3/customers/1234

In addition, API clients that still try to point to the old API should be informed to use the latest previous API version, if the API version they're using is obsolete or not supported anymore. So accessing any of the obsolete URIs like these:

http://shonzilla/api/v2.2/customers/1234
http://shonzilla/api/v2.0/customers/1234
http://shonzilla/api/v2/customers/1234
http://shonzilla/api/v1.1/customers/1234
http://shonzilla/api/v1/customers/1234

should return any of the 30x HTTP status codes that indicate redirection that are used in conjunction with Location HTTP header that redirects to the appropriate version of resource URI which remain to be this one:

http://shonzilla/api/customers/1234

There are at least two redirection HTTP status codes that are appropriate for API versioning scenarios:

• 301 Moved permanently indicating that the resource with a requested URI is moved permanently to another URI (which should be a resource instance permalink that does not contain API version info). This status code can be used to indicate an obsolete/unsupported API version, informing API client that a versioned resource URI been replaced by a resource permalink.

• 302 Found indicating that the requested resource temporarily is located at another location, while requested URI may still supported. This status code may be useful when the version-less URIs are temporarily unavailable and that a request should be repeated using the redirection address (e.g. pointing to the URI with APi version embedded) and we want to tell clients to keep using it (i.e. the permalinks).

• other scenarios can be found in Redirection 3xx chapter of HTTP 1.1 specification

@Primary annotation when used against a method like below works good if the two data sources are on the same db location/server.

@Bean(name = "datasource1")
@ConfigurationProperties("database1.datasource")
@Primary
public DataSource dataSource(){
  return DataSourceBuilder.create().build();
}

@Bean(name = "datasource2")
@ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
  return DataSourceBuilder.create().build();
}

If the data sources are on different servers its better to use @Component along with @Primary annotation. The following code snippet works well on two different data sources at different locations

database1.datasource.url = jdbc:mysql://127.0.0.1:3306/db1
database1.datasource.username = root
database1.datasource.password = mysql
database1.datasource.driver-class-name=com.mysql.jdbc.Driver

database2.datasource1.url = jdbc:mysql://192.168.113.51:3306/db2
database2.datasource1.username = root
database2.datasource1.password = mysql
database2.datasource1.driver-class-name=com.mysql.jdbc.Driver

@Configuration
@Primary
@Component
@ComponentScan("com.db1.bean")
class DBConfiguration1{
    @Bean("db1Ds")
    @ConfigurationProperties(prefix="database1.datasource")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

}

@Configuration
@Component
@ComponentScan("com.db2.bean")
class DBConfiguration2{
    @Bean("db2Ds")
    @ConfigurationProperties(prefix="database2.datasource1")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

}

My suggestion:

$.fn.attrs = function (fnc) {
    var obj = {};
    $.each(this[0].attributes, function() {
        if(this.name == 'value') return; // Avoid someone (optional)
        if(this.specified) obj[this.name] = this.value;
    });
    return obj;
}

var a = $(el).attrs();

I have tried the above methods, but feels like repetitive action when creating the view. I got the same issue while updating the views of the imported database.

You can simply overcome the issue in LOCAL by simply creating the User with the create privilege.

TLDR: use theString = theString.replace("\\", "\\\\"); instead.

Problem

replaceAll(target, replacement) uses regular expression (regex) syntax for target and partially for replacement.

Problem is that \ is special character in regex (it can be used like \d to represents digit) and in String literal (it can be used like "\n" to represent line separator or \" to escape double quote symbol which normally would represent end of string literal).

In both these cases to create \ symbol we can escape it (make it literal instead of special character) by placing additional \ before it (like we escape " in string literals via \").

So to target regex representing \ symbol will need to hold \\, and string literal representing such text will need to look like "\\\\".

So we escaped \ twice:

• once in regex \\
• once in String literal "\\\\" (each \ is represented as "\\").

In case of replacement \ is also special there. It allows us to escape other special character $ which via $x notation, allows us to use portion of data matched by regex and held by capturing group indexed as x, like "012".replaceAll("(\\d)", "$1$1") will match each digit, place it in capturing group 1 and $1$1 will replace it with its two copies (it will duplicate it) resulting in "001122".

So again, to let replacement represent \ literal we need to escape it with additional \ which means that:

• replacement must hold two backslash characters \\
• and String literal which represents \\ looks like "\\\\"

BUT since we want replacement to hold two backslashes we will need "\\\\\\\\" (each \ represented by one "\\\\").

So version with replaceAll can look like

replaceAll("\\\\", "\\\\\\\\");

Easier way

To make out life easier Java provides tools to automatically escape text into target and replacement parts. So now we can focus only on strings, and forget about regex syntax:

replaceAll(Pattern.quote(target), Matcher.quoteReplacement(replacement))

which in our case can look like

replaceAll(Pattern.quote("\\"), Matcher.quoteReplacement("\\\\"))

Even better

If we don't really need regex syntax support lets not involve replaceAll at all. Instead lets use replace. Both methods will replace all targets, but replace doesn't involve regex syntax. So you could simply write

theString = theString.replace("\\", "\\\\");

Interestingly enough, very often len(unique()) is a few times (3x-15x) faster than nunique().

Eclipse forgets to copy the default apps (ROOT, examples, etc.) when it creates a Tomcat folder inside the Eclipse workspace. Go to C:\apache-tomcat-7.0.34\webapps, R-click on the ROOT folder and copy it. Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like your-eclipse-workspace.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or .../tmp1/wtpwebapps if you already had another server registered in Eclipse). Go to the wtpwebapps folder, R-click, and paste ROOT (say "yes" if asked if you want to merge/replace folders/files). Then reload http://localhost/ to see the Tomcat welcome page.

This can help:

mysqldump --compatible=mysql40 -u user -p DB > dumpfile.sql

PHPMyAdmin has the same MySQL compatibility mode in the 'expert' export options. Although that has on occasions done nothing.

If you don't have access via the command line or via PHPMyAdmin then editing the

/*!50003 SET character_set_client  = utf8mb4 */ ; 

bit to read 'utf8' only, is the way to go.

Paxdiablo's answer is absolutely correct.

To avoid writing the return value 1 twice, I would use this instead:

=IF(OR(ISBLANK(A1),TRIM(A1)=""),1,0)

It depends on the class you are using.

Dictionary<(Of <(TKey, TValue>)>) Class For Example Support This

The Dictionary<(Of <(TKey, TValue>)>) generic class provides a mapping from a set of keys to a set of values.

For purposes of enumeration, each item in the dictionary is treated as a KeyValuePair<(Of <(TKey, TValue>)>) structure representing a value and its key. The order in which the items are returned is undefined.

foreach (KeyValuePair kvp in myDictionary) {...}

byte b = (byte)0xC8;
int v1 = b;       // v1 is -56 (0xFFFFFFC8)
int v2 = b & 0xFF // v2 is 200 (0x000000C8)

Most of the time v2 is the way you really need.

I think that you have a version 2.4.x of Apache.

I'm presenting this as a workaround rather than a solution. This may not work all the time. I did it this way as I'm doing a very basic HTML page, for internal use, in a very bizarre environment. I know there are libraries like MaterializeCSS that can do really nice nav bars. (I was going to use them, but it didn't work with my environment.)

<div id="nav" style="position:fixed;float:left;overflow-y:hidden;width:10%;"></div>
<div style="margin-left:10%;float:left;overflow-y:auto;width:60%;word-break:break-all;word-wrap:break-word;" id="content"></div>

I had also been through that problem. in my case, I was adding the data to the array and passing the array to the same array which brings the problem of memory limits. Some of the things you need to consider:

1. Review our code, look if any loop is running infinity.

2. Reduce the unwanted column if you are retrieving the data from the database.

3. Maybe you can increase the memory limits in our XAMPP other any other software you are running.

Unexpected '.'

This can occur if you are trying to use the splat operator(...) in an unsupported version of PHP.

    }
    return($transform($string));
}

echo concatenate("strtoupper", "I'd ", "like ", 4 + 2, " apples");
// This would print:
// I'D LIKE 6 APPLES

In PHP 7.4, you could use it for Array expressions.

$parts = ['apple', 'pear'];
$fruits = ['banana', 'orange', ...$parts, 'watermelon'];
// ['banana', 'orange', 'apple', 'pear', 'watermelon'];

I think, that will be good solution: /\S\w*/

If you want iterate about a list of key-value-pairs (as you wrote in the comment), then a List or an array should be better. First combine your keys and values:

public class Pair
{
   public Class1 key;
   public Class2 value;

   public Pair(Class1 key, Class2 value)
   {
      this.key = key;
      this.value = value;
   }

}

Replace Class1 and Class2 with the types you want to use for keys and values.

Now you can put them into an array or a list and iterate over them:

Pair[] pairs = new Pair[10];
...
for (Pair pair : pairs)
{
   ...
}

If you don't want to include any special character, then try this much simple way for checking special characters using RegExp \W Metacharacter.

var iChars = "~`!#$%^&*+=-[]\\\';,/{}|\":<>?";
if(!(iChars.match(/\W/g)) == "") {
    alert ("File name has special characters ~`!#$%^&*+=-[]\\\';,/{}|\":<>? \nThese are not allowed\n");
    return false;
}

sha256("string or binary");

I experienced issue with other answer. I advice you to set encoding argument to binary to use the byte string and prevent different hash between Javascript (NodeJS) and other langage/service like Python, PHP, Github...

If you don't use this code, you can get a different hash between NodeJS and Python...

How to get the same hash that Python, PHP, Perl, Github (and prevent an issue) :

NodeJS is hashing the UTF-8 representation of the string. Other languages (like Python, PHP or PERL...) are hashing the byte string.

We can add binary argument to use the byte string.

Code :

const crypto = require("crypto");

function sha256(data) {
    return crypto.createHash("sha256").update(data, "binary").digest("base64");
    //                                               ------  binary: hash the byte string
}

sha256("string or binary");

Documentation:

• crypto.createHash(algorithm[, options]): The algorithm is dependent on the available algorithms supported by the version of OpenSSL on the platform.
• hash.digest([encoding]): The encoding can be 'hex', 'latin1' or 'base64'. (base 64 is less longer).

You can get the issue with : sha256("\xac"), "\xd1", "\xb9", "\xe2", "\xbb", "\x93", etc...

• Other languages (like PHP, Python, Perl...) and my solution with .update(data, "binary") :

    sha1("\xac") //39527c59247a39d18ad48b9947ea738396a3bc47
  

• Nodejs by default (without binary) :

    sha1("\xac") //f50eb35d94f1d75480496e54f4b4a472a9148752
  

Match the identifier name at both places

This error occurs when the identifier name of the Tablecell is different in the Swift file and in the Storyboard.

For example, the identifier is placecellIdentifier in my case.

1) The Swift File

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCell(withIdentifier: "placecellIdentifier", for: indexPath)
    
    // Your code 

    return cell
}

###2) The Storyboard

Seems like your host does not provide a MySQL-version which is capable to run tables with utf8mb4 collation.

The WordPress tables were changed to utf8mb4 with Version 4.2 (released on April, 23rd 2015) to support Emojis, but you need MySQL 5.5.3 to use it. 5.5.3. is from March 2010, so it should normally be widely available. Cna you check if your hoster provides that version?

If not, and an upgrade is not possible, you might have to look out for another hoster to run the latest WordPress versions (and you should always do that for security reasons).

The only solution that worked for me is:

sudo curl https://bootstrap.pypa.io/get-pip.py | sudo python

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

Wow, after few attempts I finally figured out how to deal with my text edits in vbs. The code works perfectly, it gives me the result I was expecting. Maybe it's not the best way to do this, but it does its job. Here's the code:

Option Explicit

Life is simple if you get a good web framework. Web services in Django are easy. Define your model, write view functions that return your CSV documents. Skip the templates.

taken from : Android UI : Fixing skipped frames

Anyone who begins developing android application sees this message on logcat “Choreographer(abc): Skipped xx frames! The application may be doing too much work on its main thread.” So what does it actually means, why should you be concerned and how to solve it.

What this means is that your code is taking long to process and frames are being skipped because of it, It maybe because of some heavy processing that you are doing at the heart of your application or DB access or any other thing which causes the thread to stop for a while.

Here is a more detailed explanation:

Choreographer lets apps to connect themselves to the vsync, and properly time things to improve performance.

Android view animations internally uses Choreographer for the same purpose: to properly time the animations and possibly improve performance.

Since Choreographer is told about every vsync events, I can tell if one of the Runnables passed along by the Choreographer.post* apis doesnt finish in one frame’s time, causing frames to be skipped.

In my understanding Choreographer can only detect the frame skipping. It has no way of telling why this happens.

The message “The application may be doing too much work on its main thread.” could be misleading.

source : Meaning of Choreographer messages in Logcat

Why you should be concerned

When this message pops up on android emulator and the number of frames skipped are fairly small (<100) then you can take a safe bet of the emulator being slow – which happens almost all the times. But if the number of frames skipped and large and in the order of 300+ then there can be some serious trouble with your code. Android devices come in a vast array of hardware unlike ios and windows devices. The RAM and CPU varies and if you want a reasonable performance and user experience on all the devices then you need to fix this thing. When frames are skipped the UI is slow and laggy, which is not a desirable user experience.

How to fix it

Fixing this requires identifying nodes where there is or possibly can happen long duration of processing. The best way is to do all the processing no matter how small or big in a thread separate from main UI thread. So be it accessing data form SQLite Database or doing some hardcore maths or simply sorting an array – Do it in a different thread

Now there is a catch here, You will create a new Thread for doing these operations and when you run your application, it will crash saying “Only the original thread that created a view hierarchy can touch its views“. You need to know this fact that UI in android can be changed by the main thread or the UI thread only. Any other thread which attempts to do so, fails and crashes with this error. What you need to do is create a new Runnable inside runOnUiThread and inside this runnable you should do all the operations involving the UI. Find an example here.

So we have Thread and Runnable for processing data out of main Thread, what else? There is AsyncTask in android which enables doing long time processes on the UI thread. This is the most useful when you applications are data driven or web api driven or use complex UI’s like those build using Canvas. The power of AsyncTask is that is allows doing things in background and once you are done doing the processing, you can simply do the required actions on UI without causing any lagging effect. This is possible because the AsyncTask derives itself from Activity’s UI thread – all the operations you do on UI via AsyncTask are done is a different thread from the main UI thread, No hindrance to user interaction.

So this is what you need to know for making smooth android applications and as far I know every beginner gets this message on his console.

You can either give class name to all label so that all can have same width :

 .class-name {  width:200px;}

Example

.labelname{  width:200px;}

or you can simple give rest of label

label {  width:200px;  display: inline-block;}

Using svcutil, you can create interfaces and classes (data contracts) from the WSDL.

svcutil your.wsdl (or svcutil your.wsdl /l:vb if you want Visual Basic)

This will create a file called "your.cs" in C# (or "your.vb" in VB.NET) which contains all the necessary items.

Now, you need to create a class "MyService" which will implement the service interface (IServiceInterface) - or the several service interfaces - and this is your server instance.

Now a class by itself doesn't really help yet - you'll need to host the service somewhere. You need to either create your own ServiceHost instance which hosts the service, configure endpoints and so forth - or you can host your service inside IIS.

It is very simple do not import anything. This is my code. This will define a function that multiplies all the items in a list and returns their product.

def myfunc(lst):
    multi=1
    for product in lst:
        multi*=product
    return product

Do you mean the conversion 011001100110111101101111 ? foo, for example? You just take the binary stream, split it into separate bytes (01100110, 01101111, 01101111) and look up the ASCII character that corresponds to given number. For example, 01100110 is 102 in decimal and the ASCII character with code 102 is f:

$ perl -E 'say 0b01100110'
102
$ perl -E 'say chr(102)'
f

(See what the chr function does.) You can generalize this algorithm and have a different number of bits per character and different encodings, the point remains the same.

button:hover is just when you move the cursor over the button.
Try button:active instead...will work for other elements as well

button:active{_x000D_
  color: red;_x000D_
}

There are quite a few cross browser solutions for this today, among which are SuperTable which I like due to its elegance and simplicity (now being continued with MooGrid) and SlickGrid with its awesome set of features.

I tried to use more than two windows using the Rushy Panchal example above. The intent was to have the change to call more windows with different widgets in them. The butnew function creates different buttons to open different windows. You pass as argument the name of the class containing the window (the second argument is nt necessary, I put it there just to test a possible use. It could be interesting to inherit from another window the widgets in common.

import tkinter as tk

class Demo1:
    def __init__(self, master):
        self.master = master
        self.master.geometry("400x400")
        self.frame = tk.Frame(self.master)
        self.butnew("Window 1", "ONE", Demo2)
        self.butnew("Window 2", "TWO", Demo3)
        self.frame.pack()

    def butnew(self, text, number, _class):
        tk.Button(self.frame, text = text, width = 25, command = lambda: self.new_window(number, _class)).pack()

    def new_window(self, number, _class):
        self.newWindow = tk.Toplevel(self.master)
        _class(self.newWindow, number)


class Demo2:
    def __init__(self, master, number):
        self.master = master
        self.master.geometry("400x400+400+400")
        self.frame = tk.Frame(self.master)
        self.quitButton = tk.Button(self.frame, text = 'Quit', width = 25, command = self.close_windows)
        self.label = tk.Label(master, text=f"this is window number {number}")
        self.label.pack()
        self.quitButton.pack()
        self.frame.pack()

    def close_windows(self):
        self.master.destroy()

class Demo3:
    def __init__(self, master, number):
        self.master = master
        self.master.geometry("400x400+400+400")
        self.frame = tk.Frame(self.master)
        self.quitButton = tk.Button(self.frame, text = 'Quit', width = 25, command = self.close_windows)
        self.label = tk.Label(master, text=f"this is window number {number}")
        self.label.pack()
        self.label2 = tk.Label(master, text="THIS IS HERE TO DIFFERENTIATE THIS WINDOW")
        self.label2.pack()
        self.quitButton.pack()
        self.frame.pack()

    def close_windows(self):
        self.master.destroy()




def main(): 
    root = tk.Tk()
    app = Demo1(root)
    root.mainloop()

if __name__ == '__main__':
    main()

Open the new window only once

To avoid having the chance to press multiple times the button having multiple windows... that are the same window, I made this script (take a look at this page too)

import tkinter as tk


def new_window1():
    global win1
    try:
        if win1.state() == "normal": win1.focus()
    except:
        win1 = tk.Toplevel()
        win1.geometry("300x300+500+200")
        win1["bg"] = "navy"
        lb = tk.Label(win1, text="Hello")
        lb.pack()


win = tk.Tk()
win.geometry("200x200+200+100")
button = tk.Button(win, text="Open new Window")
button['command'] = new_window1
button.pack()
win.mainloop()

ref will probably choke on null since it presumably expects to be modifying an existing object. out expects null, since it's returning a new object.

rbind.ordered=function(x,y){

  diffCol = setdiff(colnames(x),colnames(y))
  if (length(diffCol)>0){
    cols=colnames(y)
    for (i in 1:length(diffCol)) y=cbind(y,NA)
    colnames(y)=c(cols,diffCol)
  }

  diffCol = setdiff(colnames(y),colnames(x))
  if (length(diffCol)>0){
    cols=colnames(x)
    for (i in 1:length(diffCol)) x=cbind(x,NA)
    colnames(x)=c(cols,diffCol)
  }
  return(rbind(x, y[, colnames(x)]))
}

The tricks above did not help me, as the repo was larger than the max push size allowed at github. What did work was a recommendation from https://github.com/git-lfs/git-lfs/issues/3758 which suggested pushing a bit at a time:

If your branch has a long history, you can try pushing a smaller number of commits at a time (say, 2000) with something like this:

git rev-list --reverse master | ruby -ne 'i ||= 0; i += 1; puts $_ if i % 2000 == 0' | xargs -I{} git push origin +{}:refs/heads/master

That will walk through the history of master, pushing objects 2000 at a time. (You can, of course, substitute a different branch in both places if you like.) When that's done, you should be able to push master one final time, and things should be up to date. If 2000 is too many and you hit the problem again, you can adjust the number so it's smaller.

If your HTML is well formed, I think this is a better solution:

create function dbo.StripHTML( @text varchar(max) ) returns varchar(max) as
begin
    declare @textXML xml
    declare @result varchar(max)
    set @textXML = REPLACE( @text, '&', '' );
    with doc(contents) as
    (
        select chunks.chunk.query('.') from @textXML.nodes('/') as chunks(chunk)
    )
    select @result = contents.value('.', 'varchar(max)') from doc
    return @result
end
go

select dbo.StripHTML('This <i>is</i> an <b>html</b> test')

You can also use:

@Scripts.RenderFormat("<script type=\"text/javascript\" src=\"{0}\"></script>", "~/bundles/mybundle")

To specify the format of your output in a scenario where you need to use Charset, Type, etc.

Without For loop:

Dim newColumn As New Data.DataColumn("Foo", GetType(System.String))     
newColumn.DefaultValue = "Your DropDownList value" 
table.Columns.Add(newColumn) 

C#:

System.Data.DataColumn newColumn = new System.Data.DataColumn("Foo", typeof(System.String));
newColumn.DefaultValue = "Your DropDownList value";
table.Columns.Add(newColumn);

Did you omit O, 0, and i on purpose?

I just created a PHP class based on Ryan's solution.

Try clearing your .subversion folder in your home directory and try to commit again. It should prompt you for your password and then ask you if you would like to save the password.

As Simon mentioned, this is not possible in the new Facebook API. Pure technically speaking you can do it via browser automation.

• this is against Facebook policy, so depending on the country where you live, this may not be legal
• you'll have to use your credentials / ask user for credentials and possibly store them (storing passwords even symmetrically encrypted is not a good idea)
• when Facebook changes their API, you'll have to update the browser automation code as well (if you can't force updates of your application, you should put browser automation piece out as a webservice)
• this is bypassing the OAuth concept
• on the other hand, my feeling is that I'm owning my data including the list of my friends and Facebook shouldn't restrict me from accessing those via the API

Sample implementation using WatiN:

class FacebookUser
{
  public string Name { get; set; }
  public long Id { get; set; }
}

public IList<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
  var users = new List<FacebookUser>();
  Settings.Instance.MakeNewIeInstanceVisible = false;
  using (var browser = new IE("https://www.facebook.com"))
  {
    try
    {
      browser.TextField(Find.ByName("email")).Value = email;
      browser.TextField(Find.ByName("pass")).Value = password;
      browser.Form(Find.ById("login_form")).Submit();
      browser.WaitForComplete();
    }
    catch (ElementNotFoundException)
    {
      // We're already logged in
    }
    browser.GoTo("https://www.facebook.com/friends");
    var watch = new Stopwatch();
    watch.Start();

    Link previousLastLink = null;
    while (maxTimeoutInMilliseconds.HasValue && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
    {
      var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
                       && l.GetAttributeValue("data-hovercard").Contains("user.php")
                       && l.Text != null
                     ).LastOrDefault();

      if (lastLink == null || previousLastLink == lastLink)
      {
        break;
      }

      var ieElement = lastLink.NativeElement as IEElement;
      if (ieElement != null)
      {
        var htmlElement = ieElement.AsHtmlElement;
        htmlElement.scrollIntoView();
        browser.WaitForComplete();
      }

      previousLastLink = lastLink;
    }

    var links = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
      && l.GetAttributeValue("data-hovercard").Contains("user.php")
      && l.Text != null
    ).ToList();

    var idRegex = new Regex("id=(?<id>([0-9]+))");
    foreach (var link in links)
    {
      string hovercard = link.GetAttributeValue("data-hovercard");
      var match = idRegex.Match(hovercard);
      long id = 0;
      if (match.Success)
      {
        id = long.Parse(match.Groups["id"].Value);
      }
      users.Add(new FacebookUser
      {
        Name = link.Text,
        Id = id
      });
    }
  }
  return users;
}

Prototype with implementation of this approach (using C#/WatiN) see https://github.com/svejdo1/ShadowApi. It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts.

I know that this is an old question, but I'm surprised that no answer mentions GetDateTime:

Gets the value of the specified column as a DateTime object.

Which you can use like:

while (MyReader.Read())
{
    TextBox1.Text = MyReader.GetDateTime(columnPosition).ToString("dd/MM/yyyy");
}

Below solution worked for me:

On a RecyclerView item, user will click a button but another view like TextView will update without directly notifying adapter:

I found a good solution for this without using notifyDataSetChanged() method, this method reloads all data of recyclerView so if you have image or video inside item then they will reload and user experience will not good:

Here is an example of click on a ImageView like icon and only update a single TextView (Possible to update more view in same way of same item) to show like count update after adding +1:

// View holder class inside adapter class
public class MyViewHolder extends RecyclerView.ViewHolder{

    ImageView imageViewLike;

    public MyViewHolder(View itemView) {
         super(itemView);

        imageViewLike = itemView.findViewById(R.id.imageViewLike);
        imageViewLike.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int pos = getAdapterPosition(); // Get clicked item position
                TextView tv = v.getRootView().findViewById(R.id.textViewLikeCount); // Find textView of recyclerView item
                resultList.get(pos).setLike(resultList.get(pos).getLike() + 1); // Need to change data list to show updated data again after scrolling
                tv.setText(String.valueOf(resultList.get(pos).getLike())); // Set data to TextView from updated list
            }
        });
    }

I was able to solve the issue by following these steps-

1.) This error occurs when you didn't connect your project to firebase. Do that from Tools->Firebase if you are using Android studio version 2.2 or above.

2.) Make sure you have replaced the compile with implementation in dependencies in app/build.gradle

3.) Include your firebase dependency from the firebase docs. Everything should work fine now

I had this same problem but not necessarily relating to typescript, so I struggled a bit with these different options. I am making a very basic create-react-app using a specific module react-portal-tooltip, getting similar error:

Could not find a declaration file for module 'react-portal-tooltip'. '/node_modules/react-portal-tooltip/lib/index.js' implicitly has an 'any' type. Try npm install @types/react-portal-tooltip if it exists or add a new declaration (.d.ts) file containing declare module 'react-portal-tooltip';ts(7016)

I tried many steps first - adding various .d.ts files, various npm installs.

But what eventually worked for me was touch src/declare_modules.d.ts then in src/declare_modules.d.ts:

declare module "react-portal-tooltip";

and in src/App.js:

import ToolTip from 'react-portal-tooltip';
// import './declare_modules.d.ts'

I struggled a bit with the different locations to use this general 'declare module' strategy (I am very much a beginner) so I think this will work with different options but I am included paths for what worked work me.

I initially thought import './declare_modules.d.ts' was necessary. Although now it seems like it isn't! But I am including the step in case it helps someone.

This is my first stackoverflow answer so I apologize for the scattered process here and hope it was still helpful! :)

You can programmatically import data from a csv file in your Drive into an existing Google Sheet using Google Apps Script, replacing/appending data as needed.

Below is some sample code. It assumes that: a) you have a designated folder in your Drive where the CSV file is saved/uploaded to; b) the CSV file is named "report.csv" and the data in it comma-delimited; and c) the CSV data is imported into a designated spreadsheet. See comments in code for further details.

function importData() {
  var fSource = DriveApp.getFolderById(reports_folder_id); // reports_folder_id = id of folder where csv reports are saved
  var fi = fSource.getFilesByName('report.csv'); // latest report file
  var ss = SpreadsheetApp.openById(data_sheet_id); // data_sheet_id = id of spreadsheet that holds the data to be updated with new report data

  if ( fi.hasNext() ) { // proceed if "report.csv" file exists in the reports folder
    var file = fi.next();
    var csv = file.getBlob().getDataAsString();
    var csvData = CSVToArray(csv); // see below for CSVToArray function
    var newsheet = ss.insertSheet('NEWDATA'); // create a 'NEWDATA' sheet to store imported data
    // loop through csv data array and insert (append) as rows into 'NEWDATA' sheet
    for ( var i=0, lenCsv=csvData.length; i<lenCsv; i++ ) {
      newsheet.getRange(i+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
    }
    /*
    ** report data is now in 'NEWDATA' sheet in the spreadsheet - process it as needed,
    ** then delete 'NEWDATA' sheet using ss.deleteSheet(newsheet)
    */
    // rename the report.csv file so it is not processed on next scheduled run
    file.setName("report-"+(new Date().toString())+".csv");
  }
};


// http://www.bennadel.com/blog/1504-Ask-Ben-Parsing-CSV-Strings-With-Javascript-Exec-Regular-Expression-Command.htm
// This will parse a delimited string into an array of
// arrays. The default delimiter is the comma, but this
// can be overriden in the second argument.

function CSVToArray( strData, strDelimiter ) {
  // Check to see if the delimiter is defined. If not,
  // then default to COMMA.
  strDelimiter = (strDelimiter || ",");

  // Create a regular expression to parse the CSV values.
  var objPattern = new RegExp(
    (
      // Delimiters.
      "(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +

      // Quoted fields.
      "(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +

      // Standard fields.
      "([^\"\\" + strDelimiter + "\\r\\n]*))"
    ),
    "gi"
  );

  // Create an array to hold our data. Give the array
  // a default empty first row.
  var arrData = [[]];

  // Create an array to hold our individual pattern
  // matching groups.
  var arrMatches = null;

  // Keep looping over the regular expression matches
  // until we can no longer find a match.
  while (arrMatches = objPattern.exec( strData )){

    // Get the delimiter that was found.
    var strMatchedDelimiter = arrMatches[ 1 ];

    // Check to see if the given delimiter has a length
    // (is not the start of string) and if it matches
    // field delimiter. If id does not, then we know
    // that this delimiter is a row delimiter.
    if (
      strMatchedDelimiter.length &&
      (strMatchedDelimiter != strDelimiter)
    ){

      // Since we have reached a new row of data,
      // add an empty row to our data array.
      arrData.push( [] );

    }

    // Now that we have our delimiter out of the way,
    // let's check to see which kind of value we
    // captured (quoted or unquoted).
    if (arrMatches[ 2 ]){

      // We found a quoted value. When we capture
      // this value, unescape any double quotes.
      var strMatchedValue = arrMatches[ 2 ].replace(
        new RegExp( "\"\"", "g" ),
        "\""
      );

    } else {

      // We found a non-quoted value.
      var strMatchedValue = arrMatches[ 3 ];

    }

    // Now that we have our value string, let's add
    // it to the data array.
    arrData[ arrData.length - 1 ].push( strMatchedValue );
  }

  // Return the parsed data.
  return( arrData );
};

You can then create time-driven trigger in your script project to run importData() function on a regular basis (e.g. every night at 1AM), so all you have to do is put new report.csv file into the designated Drive folder, and it will be automatically processed on next scheduled run.

If you absolutely MUST work with Excel files instead of CSV, then you can use this code below. For it to work you must enable Drive API in Advanced Google Services in your script and in Developers Console (see How to Enable Advanced Services for details).

Yes! there is a way to use a variable as a pointer in python!

I am sorry to say that many of answers were partially wrong. In principle every equal(=) assignation shares the memory address (check the id(obj) function), but in practice it is not such. There are variables whose equal("=") behaviour works in last term as a copy of memory space, mostly in simple objects (e.g. "int" object), and others in which not (e.g. "list","dict" objects).

Here is an example of pointer assignation

dict1 = {'first':'hello', 'second':'world'}
dict2 = dict1 # pointer assignation mechanism
dict2['first'] = 'bye'
dict1
>>> {'first':'bye', 'second':'world'}

Here is an example of copy assignation

a = 1
b = a # copy of memory mechanism. up to here id(a) == id(b)
b = 2 # new address generation. therefore without pointer behaviour
a
>>> 1

Pointer assignation is a pretty useful tool for aliasing without the waste of extra memory, in certain situations for performing comfy code,

class cls_X():
   ...
   def method_1():
      pd1 = self.obj_clsY.dict_vars_for_clsX['meth1'] # pointer dict 1: aliasing
      pd1['var4'] = self.method2(pd1['var1'], pd1['var2'], pd1['var3'])
   #enddef method_1
   ...
#endclass cls_X

but one have to be aware of this use in order to prevent code mistakes.

To conclude, by default some variables are barenames (simple objects like int, float, str,...), and some are pointers when assigned between them (e.g. dict1 = dict2). How to recognize them? just try this experiment with them. In IDEs with variable explorer panel usually appears to be the memory address ("@axbbbbbb...") in the definition of pointer-mechanism objects.

I suggest investigate in the topic. There are many people who know much more about this topic for sure. (see "ctypes" module). I hope it is helpful. Enjoy the good use of the objects! Regards, José Crespo

    private static Object unproxyPersistentCollection(PersistentCollection persistentCollection) {
        if (persistentCollection instanceof PersistentSet) {
            return unproxyPersistentSet((Map<?, ?>) persistentCollection.getStoredSnapshot());
        }
        return persistentCollection.getStoredSnapshot();
    }

    private static <T> Set<T> unproxyPersistentSet(Map<T, ?> persistenceSet) {
        return new LinkedHashSet<T>(persistenceSet.keySet());
    }

}

I use this function over result of my RPC services (via aspects) and it cleans recursively all result objects from proxies (if they are not initialized).

If you're worried about speed, use pointers to edit the existing string. You could pin the string and get a pointer to it, then run a for loop over each character, overwriting each invalid character with a replacement character. It would be extremely efficient and would not require allocating any new string memory. You would also need to compile your module with the unsafe option, and add the "unsafe" modifier to your method header in order to use pointers.

static void Main(string[] args)
{
    string str = "string!$%with^&*invalid!!characters";
    Console.WriteLine( str ); //print original string
    FixMyString( str, ' ' );
    Console.WriteLine( str ); //print string again to verify that it has been modified
    Console.ReadLine(); //pause to leave command prompt open
}


public static unsafe void FixMyString( string str, char replacement_char )
{
    fixed (char* p_str = str)
    {
        char* c = p_str; //temp pointer, since p_str is read-only
        for (int i = 0; i < str.Length; i++, c++) //loop through each character in string, advancing the character pointer as well
            if (!IsValidChar(*c)) //check whether the current character is invalid
                (*c) = replacement_char; //overwrite character in existing string with replacement character
    }
}

public static bool IsValidChar( char c )
{
    return (c >= '0' && c <= '9') || (c >= 'A' && c <= 'Z') || (c >= 'a' && c <= 'z') || (c == '.' || c == '_');
    //return char.IsLetterOrDigit( c ) || c == '.' || c == '_'; //this may work as well
}

As one single line (for 404 generic page):

from django.shortcuts import render_to_response
from django.template import RequestContext

return render_to_response('error/404.html', {'exception': ex},
                                      context_instance=RequestContext(request), status=404)

A better pyramid can be printed this way:

The Pattern is
     $     
    $$$    
   $$$$$   
  $$$$$$$  
 $$$$$$$$$ 
$$$$$$$$$$$

public static void main(String agrs[]) {
    System.out.println("The Pattern is");
    int size = 11; //use only odd numbers here
    for (int i = 1; i <= size; i=i+2) {
        int spaceCount = (size - i)/2;
        for(int j = 0; j< size; j++) {
            if(j < spaceCount || j >= (size - spaceCount)) {
                System.out.print(" ");
            } else {
                System.out.print("$");
            }
        }
        System.out.println();
    }
}

To complete previous answers, you can also use Wait-Job to wait for all jobs to complete:

For ($i=1; $i -le 3; $i++) {
    $ScriptBlock = {
        Param (
            [string] [Parameter(Mandatory=$true)] $increment
        )

        Write-Host $increment
    }

    Start-Job $ScriptBlock -ArgumentList $i
}

Get-Job | Wait-Job | Receive-Job

SQLite has limited ALTER TABLE support that you can use to add a column to the end of a table or to change the name of a table.

If you want to make more complex changes in the structure of a table, you will have to recreate the table. You can save existing data to a temporary table, drop the old table, create the new table, then copy the data back in from the temporary table.

For example, suppose you have a table named "t1" with columns names "a" and "c" and that you want to insert column "b" from this table. The following steps illustrate how this could be done:

BEGIN TRANSACTION;
CREATE TEMPORARY TABLE t1_backup(a,c);
INSERT INTO t1_backup SELECT a,c FROM t1;
DROP TABLE t1;
CREATE TABLE t1(a,b, c);
INSERT INTO t1 SELECT a,c FROM t1_backup;
DROP TABLE t1_backup;
COMMIT;

Now you are ready to insert your new data like so:

UPDATE t1 SET b='blah' WHERE a='key'

You should use somevar.constructor.name like a:

    _x000D_
    const getVariableType = a => a.constructor.name.toLowerCase();_x000D_
_x000D_
    const d = new Date();_x000D_
    const res1 = getVariableType(d); // 'date'_x000D_
    const num = 5;_x000D_
    const res2 = getVariableType(num); // 'number'_x000D_
    const fn = () => {};_x000D_
    const res3 = getVariableType(fn); // 'function'_x000D_
_x000D_
    console.log(res1); // 'date'_x000D_
    console.log(res2); // 'number'_x000D_
    console.log(res3); // 'function'

I use this way with Resource file (don't need Prompt anymore !)

@Html.TextBoxFor(m => m.Name, new 
{
     @class = "form-control",
     placeholder = @Html.DisplayName(@Resource.PleaseTypeName),
     autofocus = "autofocus",
     required = "required"
})

I've had similar situation and my problem was related to Active Directory and sitting behind vpn.

Found this gold after working like that for half a year: http://bjg.io/guide/cygwin-ad/

All you basicaly need is to disable db in /etc/nsswitch.conf (you can find it in your git directory) from passwd and group section, so the file looks like:

# Begin /etc/nsswitch.conf
passwd: files
group: files
db_enum: cache builtin
db_home: cygwin desc
db_shell: cygwin desc
db_gecos: cygwin desc
# End /etc/nsswitch.conf

and then update your local password and group settings once:

$ mkpasswd -l -c > /etc/passwd
$ mkgroup -l -c > /etc/group

Building on @Rob Neild's answer above, here is a pure JS adaptation that returns a simple object of decoded query string params (no %20's, etc).

function parseQueryString () {
  var parsedParameters = {},
    uriParameters = location.search.substr(1).split('&');

  for (var i = 0; i < uriParameters.length; i++) {
    var parameter = uriParameters[i].split('=');
    parsedParameters[parameter[0]] = decodeURIComponent(parameter[1]);
  }

  return parsedParameters;
}

The terms "shallow copy" and "deep copy" are a bit vague; I would suggest using the terms "memberwise clone" and what I would call a "semantic clone". A "memberwise clone" of an object is a new object, of the same run-time type as the original, for every field, the system effectively performs "newObject.field = oldObject.field". The base Object.Clone() performs a memberwise clone; memberwise cloning is generally the right starting point for cloning an object, but in most cases some "fixup work" will be required following a memberwise clone. In many cases attempting to use an object produced via memberwise clone without first performing the necessary fixup will cause bad things to happen, including the corruption of the object that was cloned and possibly other objects as well. Some people use the term "shallow cloning" to refer to memberwise cloning, but that's not the only use of the term.

A "semantic clone" is an object which is contains the same data as the original, from the point of view of the type. For examine, consider a BigList which contains an Array> and a count. A semantic-level clone of such an object would perform a memberwise clone, then replace the Array> with a new array, create new nested arrays, and copy all of the T's from the original arrays to the new ones. It would not attempt any sort of deep-cloning of the T's themselves. Ironically, some people refer to the of cloning "shallow cloning", while others call it "deep cloning". Not exactly useful terminology.

While there are cases where truly deep cloning (recursively copying all mutable types) is useful, it should only be performed by types whose constituents are designed for such an architecture. In many cases, truly deep cloning is excessive, and it may interfere with situations where what's needed is in fact an object whose visible contents refer to the same objects as another (i.e. a semantic-level copy). In cases where the visible contents of an object are recursively derived from other objects, a semantic-level clone would imply a recursive deep clone, but in cases where the visible contents are just some generic type, code shouldn't blindly deep-clone everything that looks like it might possibly be deep-clone-able.

You can use

window.top

see the following.

<head>
    <script>
    function abc() {
        alert("sss");
    }
    </script>
</head>
<body>
    <iframe id="myFrame">
        <a onclick="window.top.abc();" href="#">Click Me</a>
    </iframe>
</body>

If you are on windows and using mingw, gcc uses the win32 runtime, where printf needs %I64d for a 64 bit integer. (and %I64u for an unsinged 64 bit integer)

For most other platforms you'd use %lld for printing a long long. (and %llu if it's unsigned). This is standarized in C99.

gcc doesn't come with a full C runtime, it defers to the platform it's running on - so the general case is that you need to consult the documentation for your particular platform - independent of gcc.

I found another way in addition to command+option+shift+K. In XCode 4.2 there is an organizer that can be opened from top-right icon. You can clean all archives and saved project options from there. This helped my situation (I was seeing old removed files in the mainBundle).

Declare the variable outside of functions

function dosomething(){
  var i = 0; // Can only be used inside function
}

var i = '';
function dosomething(){
  i = 0; // Can be used inside and outside the function
}

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

I had the same problem and the following block of code was giving the same error message:

repositories.forEach( repo => {
        const commits = await getCommits(repo);
        displayCommit(commits);
});

The problem is that the method getCommits() was async but I was passing it the argument repo which was also produced by a Promise. So, I had to add the word async to it like this: async(repo) and it started working:

repositories.forEach( async(repo) => {
        const commits = await getCommits(repo);
        displayCommit(commits);
});

5 step to do what you want if you made the pull request from a forked repository:

1. reopen the pull request
2. checkout to the branch which you made the pull request
3. reset commit to the last master commit(that means remove all you new code)
4. git push --force
5. delete your forked repository which made the pull request

And everything is done, good luck!

Just use print(*(dict.keys()))

The * can be used for unpacking containers e.g. lists. For more info on * check this SO answer.

If it's working in the debug, then wait must be the proper solution.
I will suggest to use the explicit wait, as given below:

WebDriverWait wait = new WebDriverWait(new ChromeDriver(), 5);
wait.until(ExpectedConditions.presenceOfElementLocated(By.cssSelector("#Passwd")));

Try this library (javadoc is here), min API level is 7:

dependencies {
    compile 'com.shamanland:fab:0.0.8'
}

It provides single widget with ability to customize it via Theme, xml or java-code.

It's very simple to use. There are available normal and mini implementation according to Promoted Actions pattern.

<com.shamanland.fab.FloatingActionButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_my"
    app:floatingActionButtonColor="@color/my_fab_color"
    app:floatingActionButtonSize="mini"
    />

Try to compile the demo app. There is exhaustive example: light and dark themes, using with ListView, align between two Views.

Set an id attribute on the ImageView:

<ImageView android:id="@+id/myImage"

In your code where you wish to hide the image, you'll need the following code.

First, you'll need a reference to the ImageView:

ImageView myImage = (ImageView) findViewById(R.id.myImage);

Then, set Visibility to GONE:

myImage.setVisibility(View.GONE);

If you want to have code elsewhere that makes it visible again, just set it to Visible the same way:

myImage.setVisibility(View.VISIBLE);

If you mean "fully transparent", the above code works. If you mean "partially transparent", use the following method:

int alphaAmount = 128; // Some value 0-255 where 0 is fully transparent and 255 is fully opaque
myImage.setAlpha(alphaAmount);

The following code will work:

ComboBox1.SelectedIndex.Equals(String.Empty);

If a control is disabled it cannot be edited and its content is excluded when the form is submitted.

If a control is readonly it cannot be edited, but its content (if any) is still included with the submission.

Install plugin Android WiFi ADB

Check ss for your reference :

Yes. In Ruby the not equal to operator is:

The scalar formatter supports collecting the exponents. The docs are as follows:

class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter

Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.

your technique would be:

from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3))  # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)

To get the exponent displayed in the format x10^5, instantiate the ScalarFormatter with useMathText=True.

You could also use:

xfmt.set_useOffset(10000)

To get a result like this:

You can use str_pad for adding 0's

str_pad($month, 2, '0', STR_PAD_LEFT); 

string str_pad ( string $input , int $pad_length [, string $pad_string = " " [, int $pad_type = STR_PAD_RIGHT ]] )

Edit: this answer is for those who use ckeditor module in drupal.

I found a solution which doesn't require modifying ckeditor js file.

this answer is copied from here. all credits should goes to original author.

Go to "Admin >> Configuration >> CKEditor"; under Profiles, choose your profile (e.g. Full).

Edit that profile, and on "Advanced Options >> Custom JavaScript configuration" add config.allowedContent = true;.

Don't forget to flush the cache under "Performance tab."

Yet another way using just bash and grep:

For a single file 'test.txt':

  grep -q Dansk test.txt && grep -q Norsk test.txt && grep -l Svenska test.txt

Will print test.txt iff the file contains all three (in any combination). The first two greps don't print anything (-q) and the last only prints the file if the other two have passed.

If you want to do it for every file in the directory:

   for f in *; do grep -q Dansk $f && grep -q Norsk $f && grep -l Svenska $f; done

To read a file Scanner class is recommended.

    Scanner scanner = new Scanner(new FileInputStream(fFileName), fEncoding);
    try {
      while (scanner.hasNextLine()){
         System.out.println(scanner.nextLine());
      }
    }
    finally{
      scanner.close();
    }

var cur_value = $('option:selected',this).text();

Apply proper charset and collation to database, table and columns/fields.

I creates database and table structure using sql queries from one server to another. it creates database structure as follows:

1. database with charset of "utf8", collation of "utf8_general_ci"
2. tables with charset of "utf8" and collation of "utf8_bin".
3. table columns / fields have charset "utf8" and collation of "utf8_bin".

I change collation of table and column to utf8_general_ci, and it resolves the error.

To save others a few seconds, and to save them from having to read the manual, here's the short answer. Add this to the top of your make file:

.DEFAULT_GOAL := mytarget

mytarget will now be the target that is run if "make" is executed and no target is specified.

If you have an older version of make (<= 3.80), this won't work. If this is the case, then you can do what anon mentions, simply add this to the top of your make file:

.PHONY: default
default: mytarget ;

References: https://www.gnu.org/software/make/manual/html_node/How-Make-Works.html

Absolute positioning positions an element relative to its nearest positioned ancestor. So put position: relative on the container, then for child elements, top and left will be relative to the top-left of the container so long as the child elements have position: absolute. More information is available in the CSS 2.1 specification.

pluck(column_name)

This method is designed to perform select by a single column as direct SQL query Returns Array with values of the specified column name The values has same data type as column.

Examples:

Person.pluck(:id) # SELECT people.id FROM people
Person.uniq.pluck(:role) # SELECT DISTINCT role FROM people
Person.where(:confirmed => true).limit(5).pluck(:id)

see http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html#method-i-pluck

Its introduced rails 3.2 onwards and accepts only single column. In rails 4, it accepts multiple columns

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

No, the HTML5 range input only accepts one input. I would recommend you to use something like the jQuery UI range slider for that task.

non-recursive version

You don't say you want to do it recursively so I assume you only need direct children of the directory.

Sample code:

const fs = require('fs');
const path = require('path');

fs.readdirSync('your-directory-path')
  .filter((file) => fs.lstatSync(path.join(folder, file)).isFile());

In case the accepted answer by Wadih didn't work for you, try echo %CD%

just add a primary key to your table and then recreate your EF

R has a number of (undocumented) convenience functions for converting factors:

• as.character.factor
• as.data.frame.factor
• as.Date.factor
• as.list.factor
• as.vector.factor
• ...

But annoyingly, there is nothing to handle the factor -> numeric conversion. As an extension of Joshua Ulrich's answer, I would suggest to overcome this omission with the definition of your own idiomatic function:

as.numeric.factor <- function(x) {as.numeric(levels(x))[x]}

that you can store at the beginning of your script, or even better in your .Rprofile file.

Maybe this work for u

str(uuid.uuid4().fields[-1])[:5]

I found a solution to this. It's bloody witchcraft, but it works.

When you install the client, open Control Panel > Network Connections.

You'll see a disabled network connection that was added by the TAP installer (Local Area Connection 3 or some such).

Right Click it, click Enable.

The device will not reset itself to enabled, but that's ok; try connecting w/ the client again. It'll work.

"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

UPDATE only changes the values you specify:

UPDATE table SET cell='new_value' WHERE whatever='somevalue'

I had I guess the same issue. It wasnt what the fancybox properties or CSS was, but the main css for my site.

if you have something like

div {overflow:auto;height:auto;} 

for a inheritable/root in your site css then it will cause scroll bar issues in the fancy box. Remove and make your HTML and CSS more precise with IDs and classes

You can pass string parameters to JavaScript functions like below code:

I passed three parameters where the third one is a string parameter.

var btn ="<input type='button' onclick='RoomIsReadyFunc(" + ID + "," + RefId + ",\"" + YourString + "\");'  value='Room is Ready' />";

// Your JavaScript function

function RoomIsReadyFunc(ID, RefId, YourString)
{
    alert(ID);
    alert(RefId);
    alert(YourString);
}

Full credit to bchr02 for this answer. However, I had to modify it a bit to catch the scenario for lines that have */ (end of comment) followed by an empty line. The regex was matching the non empty line with */.

New: (^(\r\n|\n|\r)$)|(^(\r\n|\n|\r))|^\s*$/gm

All I did is add ^ as second character to signify the start of line.

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

Check the length of sys.argv:

if len(sys.argv) > 1:
    blah = sys.argv[1]
else:
    blah = 'blah'

Some people prefer the exception-based approach you've suggested (eg, try: blah = sys.argv[1]; except IndexError: blah = 'blah'), but I don't like it as much because it doesn't “scale” nearly as nicely (eg, when you want to accept two or three arguments) and it can potentially hide errors (eg, if you used blah = foo(sys.argv[1]), but foo(...) raised an IndexError, that IndexError would be ignored).

The for loop will be optimized by the compiler. In such cases like yours you don't need to care about optimization on your own. Trust the compiler.

BTW, if there is a way to create a string with n space characters, than it's coded the same way like you just did.

If you'd like to avoid the strtotime conversion (for example, strtotime is not being able to parse your input) you can use,

$myDateTime = DateTime::createFromFormat('Y-m-d', $dateString);
$newDateString = $myDateTime->format('d-m-Y');

Or, equivalently:

$newDateString = date_format(date_create_from_format('Y-m-d', $dateString), 'd-m-Y');

You are first giving it the format $dateString is in. Then you are telling it the format you want $newDateString to be in.

Or if the source-format always is "Y-m-d" (yyyy-mm-dd), then just use DateTime:

<?php
    $source = '2012-07-31';
    $date = new DateTime($source);
    echo $date->format('d.m.Y'); // 31.07.2012
    echo $date->format('d-m-Y'); // 31-07-2012
?>

CharsetDecoder should be what you are looking for, no ?

Many network protocols and files store their characters with a byte-oriented character set such as ISO-8859-1 (ISO-Latin-1).
However, Java's native character encoding is Unicode UTF16BE (Sixteen-bit UCS Transformation Format, big-endian byte order).

See Charset. That doesn't mean UTF16 is the default charset (i.e.: the default "mapping between sequences of sixteen-bit Unicode code units and sequences of bytes"):

Every instance of the Java virtual machine has a default charset, which may or may not be one of the standard charsets.
[US-ASCII, ISO-8859-1 a.k.a. ISO-LATIN-1, UTF-8, UTF-16BE, UTF-16LE, UTF-16]
The default charset is determined during virtual-machine startup and typically depends upon the locale and charset being used by the underlying operating system.

This example demonstrates how to convert ISO-8859-1 encoded bytes in a ByteBuffer to a string in a CharBuffer and visa versa.

// Create the encoder and decoder for ISO-8859-1
Charset charset = Charset.forName("ISO-8859-1");
CharsetDecoder decoder = charset.newDecoder();
CharsetEncoder encoder = charset.newEncoder();

try {
    // Convert a string to ISO-LATIN-1 bytes in a ByteBuffer
    // The new ByteBuffer is ready to be read.
    ByteBuffer bbuf = encoder.encode(CharBuffer.wrap("a string"));

    // Convert ISO-LATIN-1 bytes in a ByteBuffer to a character ByteBuffer and then to a string.
    // The new ByteBuffer is ready to be read.
    CharBuffer cbuf = decoder.decode(bbuf);
    String s = cbuf.toString();
} catch (CharacterCodingException e) {
}

Reimeus is right, you see this because of in.close in your chooseCave(). Also, this is wrong.

if (playAgain == "yes") {
      play = true;
}

You should use equals instead of "==".

if (playAgain.equals("yes")) {
      play = true;
}

This can a time consuming problem. For those who want to get on with their work because they do not want to waste much time, I would like to suggest that you download the zip file and unpack the zip file and use it. The zip file is available for all major OS.

https://www.eclipse.org/downloads/packages/

Here instead of hitting the Download button, which will download the Eclipse installer, scroll to the middle area where a list of the various Eclipse IDEs with their respective features are shown. Select the Eclipse IDE of your like and click on the link on the right-hand-side to download the zip or corresponding file for your OS version.

If you still want to use your other Eclipse installations because, for example, you have plugins installed, then download the Eclipse installer and on the right-hand top corner press the icon with 3 minus. After that press Update, then after restart, install the version of Eclipse IDE, which you want (the one that you want to reactivate) in a different folder. The installation will take some time. After the installation is finished you should be able to start your old Eclipse IDE.

I guess you can install it via Parallel or in any other Virtual machine with windows in it

I just figured out how to remove this gradle error, follow the following steps.

1. Go to "File".
2. Click on Invalidate Cache/ Restart.
3. Again click on Invalidate Cache / Restart(On dialoge window).

Let the gradle build without any interruption.

Thank You! Regards, hope this will help.

For frequent uses of this command I found it easy to add the location of C:\xampp\apache\bin to the PATH. Use whatever directory you have this installed in.

Then you can run from any directory in command line:

httpd -k restart

The answer above that suggests httpd -k -restart is actually a typo. You can see the commands by running httpd /?

The documentation for focusout says (emphasis mine):

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

The same distinction exists between the focusin and focus events.

The working command I'm using to execute custom SQL statements is:

results = ActiveRecord::Base.connection.execute("foo")

with "foo" being the sql statement( i.e. "SELECT * FROM table").

This command will return a set of values as a hash and put them into the results variable.

So on my rails application_controller.rb I added this:

def execute_statement(sql)
  results = ActiveRecord::Base.connection.execute(sql)

  if results.present?
    return results
  else
    return nil
  end
end

Using execute_statement will return the records found and if there is none, it will return nil.

This way I can just call it anywhere on the rails application like for example:

records = execute_statement("select * from table")

"execute_statement" can also call NuoDB procedures, functions, and also Database Views.

There is another way if all you want is the text up to the first line feed:

x='some
thing'

y=${x%$'\n'*}

After that y will contain some and nothing else (no line feed).

What is happening here?

We perform a parameter expansion substring removal (${PARAMETER%PATTERN}) for the shortest match up to the first ANSI C line feed ($'\n') and drop everything that follows (*).

For Swift 4+ versions, please use the below code:

UIDevice.current.name

your code would be

a = [0,88,26,3,48,85,65,16,97,83,91]

ind_pos = [a[1],a[5],a[7]]

print(ind_pos)

you get [88, 85, 16]

If you are using Android Studio 3.2 & above,then issue will be solved by adding google() & jcenter() to build.gradle of the project:

repositories {
        google()
        jcenter()
}

This will show you clues about why the linker doesn't want the installed library:

LD_DEBUG=all make ...

I had the same problem in a different context: my system /lib/libz.so.1 had unsatisfied dependencies on libc because I was trying to relink on a different version of the OS.

If you want to specify a list of files on the command line, and get the whole thing done in a single atomic command, try:

git apply --3way <(git show -- list-of-files)

--3way: If a patch does not apply cleanly, Git will create a merge conflict so you can run git mergetool. Omitting --3way will make Git give up on patches which don't apply cleanly.

In my case it was due to the object reference getting stale. I was automating my application using selenium webdriver, so i type something into a text box and then it navigates to another page, so while i come back on the previous page , that object gets stale. So this was causing the exception, I handled it by again initialising the elements - PageFactory.initElements(driver, Test.class;

This worked for me:

html.replace("\\/", "/").encode().decode('unicode_escape', 'surrogatepass')

This is similar to json.loads(html) behaviour

Right click on your folder on your server or local machine and give full permissions to

IIS_IUSRS

that's it.

Using table-layout: fixed as a property for table and width: calc(100%/3); for td (assuming there are 3 td's). With these two properties set, the table cells will be equal in size.

Refer to the demo.

And once you get things working again you should look into using something like subversion or mercurial for backup and revision control. Remember that he electrons don't always go where they are supposed to, backup early and often!

Without favouring any particular naming choice, remember that a git repo can be cloned into any root directory of your choice:

git clone https://github.com/user/repo.git myDir

Here repo.git would be cloned into the myDir directory.

So even if your naming convention for a public repo ended up to be slightly incorrect, it would still be possible to fix it on the client side.

That is why, in a distributed environment where any client can do whatever he/she wants, there isn't really a naming convention for Git repo.
(except to reserve "xxx.git" for bare form of the repo 'xxx')
There might be naming convention for REST service (similar to "Are there any naming convention guidelines for REST APIs?"), but that is a separate issue.

I found that I needed to group by the month and year so neither of the above worked for me. Instead I used date_format

SELECT date
FROM blog 
GROUP BY DATE_FORMAT(date, "%m-%y")
ORDER BY YEAR(date) DESC, MONTH(date) DESC 

I've modified sussudio answer. Now function returns: (returncode, stdout, stderr, timeout) - stdout and stderr is decoded to utf-8 string

def kill_proc(proc, timeout):
  timeout["value"] = True
  proc.kill()

def run(cmd, timeout_sec):
  proc = subprocess.Popen(shlex.split(cmd), stdout=subprocess.PIPE, stderr=subprocess.PIPE)
  timeout = {"value": False}
  timer = Timer(timeout_sec, kill_proc, [proc, timeout])
  timer.start()
  stdout, stderr = proc.communicate()
  timer.cancel()
  return proc.returncode, stdout.decode("utf-8"), stderr.decode("utf-8"), timeout["value"]

three different approaches:

1. Classic client/server approach: don't put any database in the shops; simply have the applications access your server. Of course it's better if you set a VPN, but simply wrapping the connection in SSL or ssh is reasonable. Pro: it's the way databases were originally thought. Con: if you have high latency, complex operations could get slow, you might have to use stored procedures to reduce the number of round trips.

2. replicated master/master: as @Book Of Zeus suggested. Cons: somewhat more complex to setup (especially if you have several shops), breaking in any shop machine could potentially compromise the whole system. Pros: better responsivity as read operations are totally local and write operations are propagated asynchronously.

3. offline operations + sync step: do all work locally and from time to time (might be once an hour, daily, weekly, whatever) write a summary with all new/modified records from the last sync operation and send to the server. Pros: can work without network, fast, easy to check (if the summary is readable). Cons: you don't have real-time information.

SQLite has a printf function which does exactly that:

SELECT printf('%s-%.2d-%.4d', col1, col2, col3) FROM mytable

If issue remains even after updating dependency version, then delete everything present under
C:\Users\[your_username]\.m2\repository\com\fasterxml

And, make sure following dependencies are present:

Others have given you the answer about appendChild.

Calling document.write() on a page that is not open (e.g. has finished loading) first calls document.open() which clears the entire content of the document (including the script calling document.write), so it's rarely a good idea to do that.

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

1. Go to Control Panel -> Programs -> Programs and features

   

2. Go to Windows Features and disable Internet Explorer 11

   

   

3. Then click on Display installed updates

   

4. Search for Internet explorer

5. Right-click on Internet Explorer 11 -> Uninstall

   

6. Do the same with Internet Explorer 10

7. Restart your computer
8. Install Internet Explorer 10 here (old broken link)

I think it will be okay.

I encountered this error when inheriting from an abstract class and not implementing all of the pure virtual methods in my subclass.

There is a way to do key listeners in python. This functionality is available through pynput.

Command line:

$ pip install pynput

Python code:

Other answers are correct, but in my case I need to handle other properties also (alpha, animate, completion). Because of this, I modified a bit to expose these parameters as below:

extension UIView {
    /// Helper function to update view's alpha with animation
    /// - Parameter alpha: View's alpha
    /// - Parameter animate: Indicate alpha changing with animation or not
    /// - Parameter duration: Indicate time for animation
    /// - Parameter completion: Completion block after alpha changing is finished
    func set(alpha: CGFloat, animate: Bool, duration: TimeInterval = 0.3, completion: ((Bool) -> Void)? = nil) {
        let animation = { (view: UIView) in
            view.alpha = alpha
        }
    
        if animate {
            UIView.animate(withDuration: duration, animations: {
                animation(self)
            }, completion: { finished in
                completion?(finished)
            })
        } else {
            layer.removeAllAnimations()
            animation(self)
            completion?(true)
        }
    }
}

Excel has no way of gathering that attribute with it's built-in functions. If you're willing to use some VB, all your color-related questions are answered here:

http://www.cpearson.com/excel/colors.aspx

Example form the site:

The SumColor function is a color-based analog of both the SUM and SUMIF function. It allows you to specify separate ranges for the range whose color indexes are to be examined and the range of cells whose values are to be summed. If these two ranges are the same, the function sums the cells whose color matches the specified value. For example, the following formula sums the values in B11:B17 whose fill color is red.

=SUMCOLOR(B11:B17,B11:B17,3,FALSE)

rngYourRange.Address(,,,TRUE)

Shows External Address, Full Address

Setting environment variable JAVA_HOME to JDK 5 or 6 (instead of JDK 7) fixed the error.

If its in a landscape then you will be needing more width and less height! That's just what all websites have.

Lets go with a basic first then the rest!

The basic CSS:

By CSS you can do this,

#body {
width: 100%;
height: 100%;
}

Here you are using a div with id body, as:

<body>
  <div id="body>
    all the text would go here!
  </div>
</body>

Then you can have a web page with 100% height and width.

What if he tries to resize the window?

The issues pops up, what if he tries to resize the window? Then all the elements inside #body would try to mess up the UI. For that you can write this:

#body {
height: 100%;
width: 100%;
}

And just add min-height max-height min-width and max-width.

This way, the page element would stay at the place they were at the page load.

Using JavaScript:

Using JavaScript, you can control the UI, use jQuery as:

$('#body').css('min-height', '100%');

And all other remaining CSS properties, and JS will take care of the User Interface when the user is trying to resize the window.

How to not add scroll to the web page:

If you are not trying to add a scroll, then you can use this JS

$('#body').css('min-height', screen.height); // or anyother like window.height

This way, the document will get a new height whenever the user would load the page.

Second option is better, because when users would have different screen resolutions they would want a CSS or Style sheet created for their own screen. Not for others!

Tip: So try using JS to find current Screen size and edit the page! :)

Best solution for me, paste your class

@Override
public void onResume() {
    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    super.onResume();
}

@Override
public void onStart() {
    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    super.onStart();
}

The answer comes from the javadoc of ZoneId (emphasis mine) ...

A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:

• Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
• Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply

Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.

... and from the javadoc of ZoneId#of (emphasis mine):

This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.

The argument id is specified as "UTC", therefore it will return a ZoneId with an offset, which also presented in the string form:

System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));

Outputs:

2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]

As you use the equals method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false.

When the normalized() method is used as proposed in the documentation, the comparison using equals will return true, as normalized() will return the corresponding ZoneOffset:

Normalizes the time-zone ID, returning a ZoneOffset where possible.

now.withZoneSameInstant(ZoneOffset.UTC)
    .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true

As the documentation states, if you use "Z" or "+0" as input id, of will return the ZoneOffset directly and there is no need to call normalized():

now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true

To check if they store the same date time, you can use the isEqual method instead:

now.withZoneSameInstant(ZoneOffset.UTC)
    .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true

Sample

System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
        .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));

Output:

equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true

Confining Mutability to Builders

The top answers here correctly speak to the difference in Kotlin between read-only List (NOTE: it's read-only, not "immutable"), and MutableList.

In general, one should strive to use read-only lists, however, mutability is still often useful at construction time, especially when dealing with third-party libraries with non-functional interfaces. For cases in which alternate construction techniques are not available, such as using listOf directly, or applying a functional construct like fold or reduce, a simple "builder function" construct like the following nicely produces a read-only list from a temporary mutable one:

val readonlyList = mutableListOf<...>().apply {
  // manipulate your list here using whatever logic you need
  // the `apply` function sets `this` to the `MutableList`
  add(foo1)
  addAll(foos)
  // etc.
}.toList()

and this can be nicely encapsulated into a re-usable inline utility function:

inline fun <T> buildList(block: MutableList<T>.() -> Unit) = 
  mutableListOf<T>().apply(block).toList()

which can be called like this:

val readonlyList = buildList<String> {
  add("foo")
  add("bar")
}

Now, all of the mutability is isolated to one block scope used for construction of the read-only list, and the rest of your code uses the read-only list that is output from the builder.

UPDATE: As of Kotlin 1.3.70, the exact buildList function above is available in the standard library as an experimental function, along with its analogues buildSet and buildMap. See https://blog.jetbrains.com/kotlin/2020/03/kotlin-1-3-70-released/.

Use the parseJSON method:

var json = '["City1","City2","City3"]';
var arr = $.parseJSON(json);

Then you have an array with the city names.

In HTML Lang, these two tags are used as follows:

simple text this is test text normal text



simple text this is important textwith normal text

The major diversity between these two HTML tags is that bold makes text only visually look bold, while strong also symbolism hit the respective text as essential and indicates that it is a clear word or text section.

This difference is due to the fact that HTML code differentiates between symbolism and physical visual html tags. While the earlier refer to the meaning of the relevant areas, the latter merely define the optical display in browsers. You can check this from here

This worked fine with me url:http://example.com/rest/muqsith/get-file?filePath=C:\Users\I066807\Desktop\test.xml

@Produces({ MediaType.APPLICATION_OCTET_STREAM })
@Path("/get-file")
public Response getFile(@Context HttpServletRequest request){
   String filePath = request.getParameter("filePath");
   if(filePath != null && !"".equals(filePath)){
        File file = new File(filePath);
        StreamingOutput stream = null;
        try {
        final InputStream in = new FileInputStream(file);
        stream = new StreamingOutput() {
            public void write(OutputStream out) throws IOException, WebApplicationException {
                try {
                    int read = 0;
                        byte[] bytes = new byte[1024];

                        while ((read = in.read(bytes)) != -1) {
                            out.write(bytes, 0, read);
                        }
                } catch (Exception e) {
                    throw new WebApplicationException(e);
                }
            }
        };
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
        return Response.ok(stream).header("content-disposition","attachment; filename = "+file.getName()).build();
        }
    return Response.ok("file path null").build();
}

Partial Dependency is one kind of functional dependency that occur when primary key must be candidate key and non prime attribute are depends on the subset/part of candidates key (more than one primary key).

Try to understand partial dependency relate through example :

Seller(Id, Product, Price)

Candidate Key : Id, Product
Non prime attribute : Price

Price attribute only depends on only Product attribute which is a subset of candidate key, Not the whole candidate key(Id, Product) key . It is called partial dependency.

So we can say that Product->Price is partial dependency.

In my case, the message was caused by a synonym which inadvertently included the database name in the "object name". When I restored the database under a new name, the synonym still pointed to the old DB name. Since the user did not have permissions in the old DB, the message appeared. To fix, I dropped and recreated the synonym without qualifying the object name with the database name:

    USE [new_db]
GO

/****** Object:  Synonym [dbo].[synTable]    Script Date: 10/15/2015 9:45:01 AM ******/
DROP SYNONYM [dbo].[synTable]
GO

/****** Object:  Synonym [dbo].[synTable]    Script Date: 10/15/2015 9:45:01 AM ******/
CREATE SYNONYM [dbo].[synTable] FOR [dbo].[tTheRealTable]
GO

Try this:

\?(.*)

The parentheses are a capturing group that you can use to extract the part of the string you are interested in.

If the string can contain new lines you may have to use the "dot all" modifier to allow the dot to match the new line character. Whether or not you have to do this, and how to do this, depends on the language you are using. It appears that you forgot to mention the programming language you are using in your question.

Another alternative that you can use if your language supports fixed width lookbehind assertions is:

(?<=\?).*

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

A much better way I think would be something like this:

Service:

app.service('FruitsManager',function($q){

    function getAllFruits(){
        var deferred = $q.defer();

        ...

        // somewhere here use: deferred.resolve(awesomeFruits);

        ...

        return deferred.promise;
    }

    return{
        getAllFruits:getAllFruits
    }

});

And in the controller you can simply use:

$scope.fruits = FruitsManager.getAllFruits();

Angular will automatically put the resolved awesomeFruits into the $scope.fruits.

ClickOnce apps are designed so that the end user downloads a "downloader" - the ClickOnce app, then when ya run it, it downloads and installs in %LocalAppData%\Apps\2.0..... and then it's random folder names for every OS install you do. Backing up is pointless and so is trying to move the program. The point of ClickOnce is 2-Fold: 1. AutoUpdating of the program 2. The end user has no installer and also can't move the app or it breaks

The %LocalAppData%\Apps\2.0..... folder is the program AND %LocalAppData%\GitHub is the settings folder.

I'm not going to cover how to circumvent this - only stating the above. :P

The best 'tip' I can say legitimately is: You 'can' in some cases move the final folder that all the files are in and use a symlink back, if you are low on space. But, not all apps will work and essentially will delete the symlink once you they run. Then they might reinstall or simply just remove the link. Keep in mind also, other apps may be using that same final folder as well, so move the folder will affect those too.

EDIT: After your comments, I understand that you want to pass variable through your form.

You can do this using hidden field:

<input type='hidden' name='var' value='<?php echo "$var";?>'/> 

In PHP action File:

<?php 
   if(isset($_POST['var'])) $var=$_POST['var'];
?>

Or using sessions: In your first page:

 $_SESSION['var']=$var;

start_session(); should be placed at the beginning of your php page.

In PHP action File:

if(isset($_SESSION['var'])) $var=$_SESSION['var'];

First Answer:

You can also use $GLOBALS :

if (isset($_POST['save_exit']))
{

   echo $GLOBALS['var']; 

}

Check this documentation for more informations.

The closest you can get to that kind of behavior with switch statements is

switch (num) {
case 1:
case 2:
case 3:
case 4:
case 5:
     System.out.println("1 through 5");
     break;
case 6:
case 7:
case 8:
case 9:
case 10:
     System.out.println("6 through 10");
     break;
}

Use if statements.

From the MySQL manual

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas. Example:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

You can use console consumer to view messages produced on some topic:

bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning

The property event.which is added when using jQuery to avoid browser differences. See docs.

The which property will be undefined if you are not using jQuery.

You need to set the parent element to 100% as well

html, body {
    height: 100%;
}

Demo (Changed the background for demo purpose)

Also, when you want to cover entire screen, seems like you want to dim, so in this case, you need to use position: fixed;

#dimScreen {
    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5); 
    position: fixed;
    top: 0;
    left: 0;
    z-index: 100; /* Just to keep it at the very top */
}

If that's the case, than you don't need html, body {height: 100%;}

Demo 2

MY SOLUTION!!!!!!! I fixed this problem when I was trying to install business objects. When the installer failed to register .dll's I inputted the MSVCR71.dll into both system32 and sysWOW64 then clicked retry. Installation finished. I did try adding this in before and after install but, install still failed.

The default name for a configuration file is [yourexe].exe.config. So notepad.exe will have a configuration file named notepad.exe.config, in the same folder as the program. This is a general configuration file for all aspects of the CLR and Framework, but it can contain your own settings under an <appSettings> node.

The <appSettings> element creates a collection of name-value pairs which can be accessed as System.Configuration.ConfigurationSettings.AppSettings. There is no way to save changes back to the configuration file, however.

It is also possible to add your own custom elements to a configuration file - for example, to define a structured setting - by creating a class that implements IConfigurationSectionHandler and adding it to the <configSections> element of the configuration file. You can then access it by calling ConfigurationSettings.GetConfig.

.NET 2.0 adds a new class, System.Configuration.ConfigurationManager, which supports multiple files, with per-user overrides of per-system data. It also supports saving modified configurations back to settings files.

Visual Studio creates a file called App.config, which it copies to the EXE folder, with the correct name, when the project is built.

In question title you write about string conversion, but in question you talk about binary data (picture) so here is function which make proper conversion starting from PNG picture binary data (details and reversal conversion here )

function bytesArrToBase64(arr) {
  const abc = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"; // base64 alphabet
  const bin = n => n.toString(2).padStart(8,0); // convert num to 8-bit binary string
  const l = arr.length
  let result = '';

  for(let i=0; i<=(l-1)/3; i++) {
    let c1 = i*3+1>=l; // case when "=" is on end
    let c2 = i*3+2>=l; // case when "=" is on end
    let chunk = bin(arr[3*i]) + bin(c1? 0:arr[3*i+1]) + bin(c2? 0:arr[3*i+2]);
    let r = chunk.match(/.{1,6}/g).map((x,j)=> j==3&&c2 ? '=' :(j==2&&c1 ? '=':abc[+('0b'+x)]));  
    result += r.join('');
  }

  return result;
}

We managed to get this working exactly as described in the OP, and hopefully someone else can make use of the solution. Here's what we did:

Set up the security context like so:

<security:http realm="Protected API" use-expressions="true" auto-config="false" create-session="stateless" entry-point-ref="CustomAuthenticationEntryPoint">
    <security:custom-filter ref="authenticationTokenProcessingFilter" position="FORM_LOGIN_FILTER" />
    <security:intercept-url pattern="/authenticate" access="permitAll"/>
    <security:intercept-url pattern="/**" access="isAuthenticated()" />
</security:http>

<bean id="CustomAuthenticationEntryPoint"
    class="com.demo.api.support.spring.CustomAuthenticationEntryPoint" />

<bean id="authenticationTokenProcessingFilter"
    class="com.demo.api.support.spring.AuthenticationTokenProcessingFilter" >
    <constructor-arg ref="authenticationManager" />
</bean>

As you can see, we've created a custom AuthenticationEntryPoint, which basically just returns a 401 Unauthorized if the request wasn't authenticated in the filter chain by our AuthenticationTokenProcessingFilter.

CustomAuthenticationEntryPoint:

public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response,
            AuthenticationException authException) throws IOException, ServletException {
        response.sendError( HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized: Authentication token was either missing or invalid." );
    }
}

AuthenticationTokenProcessingFilter:

public class AuthenticationTokenProcessingFilter extends GenericFilterBean {

    @Autowired UserService userService;
    @Autowired TokenUtils tokenUtils;
    AuthenticationManager authManager;

    public AuthenticationTokenProcessingFilter(AuthenticationManager authManager) {
        this.authManager = authManager;
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        @SuppressWarnings("unchecked")
        Map<String, String[]> parms = request.getParameterMap();

        if(parms.containsKey("token")) {
            String token = parms.get("token")[0]; // grab the first "token" parameter

            // validate the token
            if (tokenUtils.validate(token)) {
                // determine the user based on the (already validated) token
                UserDetails userDetails = tokenUtils.getUserFromToken(token);
                // build an Authentication object with the user's info
                UsernamePasswordAuthenticationToken authentication = 
                        new UsernamePasswordAuthenticationToken(userDetails.getUsername(), userDetails.getPassword());
                authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails((HttpServletRequest) request));
                // set the authentication into the SecurityContext
                SecurityContextHolder.getContext().setAuthentication(authManager.authenticate(authentication));         
            }
        }
        // continue thru the filter chain
        chain.doFilter(request, response);
    }
}

Obviously, TokenUtils contains some privy (and very case-specific) code and can't be readily shared. Here's its interface:

public interface TokenUtils {
    String getToken(UserDetails userDetails);
    String getToken(UserDetails userDetails, Long expiration);
    boolean validate(String token);
    UserDetails getUserFromToken(String token);
}

That ought to get you off to a good start. Happy coding. :)

After fetching a zillion times still added remotes didn't show up, although the blobs were in the pool. Turns out the --tags option shouldn't be given to git remote add for whatever reason. You can manually remove it from the .git/config to make git fetch create the refs.

When Xcode asks you to reset certs, you reset it. And the app can be run on actual device without crash with that error messages. Once this problem is fixed in one swift project. Other swift projects with this problem are fixed also.

I have struggled for these about half a day and I found that reset certs again and again in provisioning portal doesn't help.

Here is a work around I found if you want to only shuffle a subset of the DataFrame:

shuffle_to_index = 20
df = pd.concat([df.iloc[np.random.permutation(range(shuffle_to_index))], df.iloc[shuffle_to_index:]])

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

You can also use XWiki HTML Cleaner:

It uses HTMLCleaner and extends it to generate valid XHTML 1.1 content.

The shebang line in any script determines the script's ability to be executed like a standalone executable without typing python beforehand in the terminal or when double clicking it in a file manager (when configured properly). It isn't necessary but generally put there so when someone sees the file opened in an editor, they immediately know what they're looking at. However, which shebang line you use IS important.

Correct usage for Python 3 scripts is:

#!/usr/bin/env python3

This defaults to version 3.latest. For Python 2.7.latest use python2 in place of python3.

The following should NOT be used (except for the rare case that you are writing code which is compatible with both Python 2.x and 3.x):

#!/usr/bin/env python

The reason for these recommendations, given in PEP 394, is that python can refer either to python2 or python3 on different systems. It currently refers to python2 on most distributions, but that is likely to change at some point.

Also, DO NOT Use:

#!/usr/local/bin/python

"python may be installed at /usr/bin/python or /bin/python in those cases, the above #! will fail."

--"#!/usr/bin/env python" vs "#!/usr/local/bin/python"
