I had similar problem (in bash terminal command was working correctly but zsh showed command not found error)

Solution:

just paste whatever you were earlier pasting in ~/.bashrc to:

~/.zshrc

RFC6648 recommends that you assume that your custom header "might become standardized, public, commonly deployed, or usable across multiple implementations." Therefore, it recommends not to prefix it with "X-" or similar constructs.

However, there is an exception "when it is extremely unlikely that [your header] will ever be standardized." For such "implementation-specific and private-use" headers, the RFC says a namespace such as a vendor prefix is justified.

Easy. To change a time value like: 1:00:15 to text, you can use the 'TEXT' function. Example, if your time value (1:00:15) is contained in cell 'A1', you can convert it into a text by doing: Text(A1, "h:mm:ss"). The result still looks the same: 1:00:15. But notice that this time round, it has become a text value.

Use the simple way:

<%= Html.RadioButtonFor(m => m.Gender, "Male", new { Checked = "checked" })%>

Your web pages are served by an application pool. If you disable/stop the application pool, and anyone tries to browse the application, you will get a Service Unavailable. It can happen due to multiple reasons...

1. Your application may have crashed [check the event viewer and see if you can find event logs in your Application/System log]

2. Your application may be crashing very frequently. If an app pool crashes for 5 times in 5 minutes [check your application pool settings for rapid fail], your application pool is disabled by IIS and you will end up getting this message.

In either case, the issue is that your worker process is failing and you should troubleshoot it from crash perspective.

What is a Crash (technically)... in ASP.NET and what to do if it happens?

Using guava:

List<String> stringList=Lists.transform(list,new Function<Object,String>(){
    @Override
    public String apply(Object arg0) {
        if(arg0!=null)
            return arg0.toString();
        else
            return "null";
    }
});

I recently had this issue. The problem was that the method I was trying to mock had no access modifier. Adding public solved the problem.

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

C++11/14/17/… References:

• The C++11/14/17 Standard (INCITS/ISO/IEC 14882:2011/2014/2017) This, of course, is the final arbiter of all that is or isn't C++. Be aware, however, that it is intended purely as a reference for experienced users willing to devote considerable time and effort to its understanding. The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US). For most people, the final draft before standardization is more than adequate (and free). Many will prefer an even newer draft, documenting new features that are likely to be included in C++20.

• Overview of the New C++ (C++11/14) (PDF only) (Scott Meyers) (updated for C++14) These are the presentation materials (slides and some lecture notes) of a three-day training course offered by Scott Meyers, who's a highly respected author on C++. Even though the list of items is short, the quality is high.

• The C++ Core Guidelines (C++11/14/17/…) (edited by Bjarne Stroustrup and Herb Sutter) is an evolving online document consisting of a set of guidelines for using modern C++ well. The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management and concurrency affecting application architecture and library design. The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support. Many rules are designed specifically to be automatically checkable by static analysis tools.

• The C++ Super-FAQ (Marshall Cline, Bjarne Stroustrup and others) is an effort by the Standard C++ Foundation to unify the C++ FAQs previously maintained individually by Marshall Cline and Bjarne Stroustrup and also incorporating new contributions. The items mostly address issues at an intermediate level and are often written with a humorous tone. Not all items might be fully up to date with the latest edition of the C++ standard yet.

• cppreference.com (C++03/11/14/17/…) (initiated by Nate Kohl) is a wiki that summarizes the basic core-language features and has extensive documentation of the C++ standard library. The documentation is very precise but is easier to read than the official standard document and provides better navigation due to its wiki nature. The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

Classics / Older

Note: Some information contained within these books may not be up-to-date or no longer considered best practice.

• The Design and Evolution of C++ (Bjarne Stroustrup) If you want to know why the language is the way it is, this book is where you find answers. This covers everything before the standardization of C++.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

Terminating a connection open with vagrant ssh will show the address, so a dummy or empty command can be executed:

$ vagrant ssh -c ''
Connection to 192.168.121.155 closed.

The point of rest is that if we agree to use a common language for basic operations (the http verbs), the infrastructure can be configured to understand them and optimize them properly, for example, by making use of caching headers to implement caching at all levels.

With a properly implemented restful GET operation, it shouldn't matter if the information comes from your server's DB, your server's memcache, a CDN, a proxy's cache, your browser's cache or your browser's local storage. The fasted, most readily available up to date source can be used.

Saying that Rest is just a syntactic change from using GET requests with an action parameter to using the available http verbs makes it look like it has no benefits and is purely cosmetic. The point is to use a language that can be understood and optimized by every part of the chain. If your GET operation has an action with side effects, you have to skip all HTTP caching or you'll end up with inconsistent results.

It should be like this.

In your Component

computed: {
        ...mapGetters({
                nameFromStore: 'name'
            }),
        name: {
           get(){
             return this.nameFromStore
           },
           set(newName){
             return newName
           } 
        }
    }

In your store

export const store = new Vuex.Store({
         state:{
             name : "Stackoverflow"
         },
         getters: {
                 name: (state) => {
                     return state.name;
                 }
         }
}

You may try

$("#addRunner input").each(function(){ ... });

Inputs are no selectors, so you do not need the : Haven't tested it with your code. Just a fast guess!

Normal arithmetic is base-10, so decimals represent tenths, hundredths, etc. When you try to represent a floating-point number in binary base-2 arithmetic, you are dealing with halves, fourths, eighths, etc.

In the hardware, floating points are stored as integer mantissas and exponents. Mantissa represents the significant digits. Exponent is like scientific notation but it uses a base of 2 instead of 10. For example 64.0 would be represented with a mantissa of 1 and exponent of 6. 0.125 would be represented with a mantissa of 1 and an exponent of -3.

Floating point decimals have to add up negative powers of 2

0.1b = 0.5d
0.01b = 0.25d
0.001b = 0.125d
0.0001b = 0.0625d
0.00001b = 0.03125d

and so on.

It is common to use a error delta instead of using equality operators when dealing with floating point arithmetic. Instead of

if(a==b) ...

you would use

delta = 0.0001; // or some arbitrarily small amount
if(a - b > -delta && a - b < delta) ...

In order to do the database style ComboBoxes manually trying to setup a relationship between a number (internal) and some text (visible), I've found you have to:

1. Store you items in a list (You are close - except the string,string - need int,string)
2. DataSource property to the list (You are good)
3. DataMember,DataValue (You are good)
4. Load default value (You are good)
5. Put in value from database (Your question)
6. Get value to put back in database (Your next question)

First things first. Change your KeyValuePair to so it looks like:

(0,"Select") (1,"Option 1")

Now, when you run your sql "Select empstatus from employees where blah" and get back an integer, you need to set the combobox without wasting a bunch of time.

Simply: *** SelectedVALUE - not Item ****

cmbEmployeeStatus.SelectedValue = 3;   //or

cmbEmployeeStatus.SelectedValue = intResultFromQuery;   

This will work whether you have manually loaded the combobox with code values, as you did, or if you load the comboBox from a query.

If your foreign keys are integers, (which for what I do, they all are), life is easy. After the user makes the change to the comboBox, the value you will store in the database is SelectedValue. (Cast to int as needed.)

Here is my code to set the ComboBox to the value from the database:

if (t is DBInt) //Typical for ComboBox stuff
    {
    cb.SelectedValue = ((DBInt)t).value;
    }

And to retrieve:

((DBInt)t).value = (int) cb.SelectedValue;

DBInt is a wrapper for an Integer, but this is part of my ORM that gives me manual control over databinding, and reduces code errors.

Why did I answer this so late? I was struggling with this also, as there seems to be no good info on the web about how to do this. I figured it out, and thought I'd be nice and post it for someone else to see.

Although an old question all the contributions helped me a lot so here's my solution, which works within my own DbContext class. The $rows parameter is simply an array of associative arrays representing rows or models: field name => insert value.

If you use a pattern that uses models this fits in nicely when passed model data as an array, say from a ToRowArray method within the model class.

Note: It should go without saying but never allow the arguments passed to this method to be exposed to the user or reliant on any user input, other than the insert values, which have been validated and sanitised. The $tableName argument and the column names should be defined by the calling logic; for instance a User model could be mapped to the user table, which has its column list mapped to the model's member fields.

public function InsertRange($tableName, $rows)
{
    // Get column list
    $columnList = array_keys($rows[0]);
    $numColumns = count($columnList);
    $columnListString = implode(",", $columnList);

    // Generate pdo param placeholders
    $placeHolders = array();

    foreach($rows as $row)
    {
        $temp = array();

        for($i = 0; $i < count($row); $i++)
            $temp[] = "?";

        $placeHolders[] = "(" . implode(",", $temp) . ")";
    }

    $placeHolders = implode(",", $placeHolders);

    // Construct the query
    $sql = "insert into $tableName ($columnListString) values $placeHolders";
    $stmt = $this->pdo->prepare($sql);

    $j = 1;
    foreach($rows as $row)
    {
        for($i = 0; $i < $numColumns; $i++)
        {
            $stmt->bindParam($j, $row[$columnList[$i]]);
            $j++;
        }
    }

    $stmt->execute();
}

Check out this page: https://developer.mozilla.org/En/DOM/Document.getElementsByName

document.getElementsByName('foo')[0]; // returns you element.

It has to be 'elements' and must return an array because more than one element could have the same name.

I had an issue with this in an NUnit 2.6.4 project targeting dotnet framework 4.6.2. I ran into that System.Runtime FileNotFound error trying to use Humanizer.

I fixed my error by installing NetStandard.Library into my unit test project.

Its my code

jQuery(document).ready(function(e) {
    var WindowHeight = jQuery(window).height();

    var load_element = 0;

    //position of element
    var scroll_position = jQuery('.product-bottom').offset().top;

    var screen_height = jQuery(window).height();
    var activation_offset = 0;
    var max_scroll_height = jQuery('body').height() + screen_height;

    var scroll_activation_point = scroll_position - (screen_height * activation_offset);

    jQuery(window).on('scroll', function(e) {

        var y_scroll_pos = window.pageYOffset;
        var element_in_view = y_scroll_pos > scroll_activation_point;
        var has_reached_bottom_of_page = max_scroll_height <= y_scroll_pos && !element_in_view;

        if (element_in_view || has_reached_bottom_of_page) {
            jQuery('.product-bottom').addClass("change");
        } else {
            jQuery('.product-bottom').removeClass("change");
        }

    });

});

Its working Fine

Yes. By default, ASP.NET MVC checks first in \Views\[Controller_Dir]\, but after that, if it doesn't find the view, it checks in \Views\Shared.

The shared directory is there specifically to share Views across multiple controllers. Just add your View to the Shared subdirectory and you're good to go.

If you do return View("~/Views/Wherever/SomeDir/MyView.aspx") You can return any View you'd like.

If you need the construct for a quick example to play with, use the : operator.

But if you are creating a vector/range of numbers dynamically, then use seq() instead.

Let's say you are creating the vector/range of numbers from a to b with a:b, and you expect it to be an increasing series. Then, if b is evaluated to be less than a, you will get a decreasing sequence but you will never be notified about it, and your program will continue to execute with the wrong kind of input.

In this case, if you use seq(), you can set the sign of the by argument to match the direction of your sequence, and an error will be raised if they do not match. For example,

seq(a, b, -1)

will raise an error for a=2, b=6, because the coder expected a decreasing sequence.

I'm using a slightly different approach where public struct methods implement interfaces but their logic is limited to just wrapping private (unexported) functions which take those interfaces as parameters. This gives you the granularity you would need to mock virtually any dependency and yet have a clean API to use from outside your test suite.

To understand this it is imperative to understand that you have access to the unexported methods in your test case (i.e. from within your _test.go files) so you test those instead of testing the exported ones which have no logic inside beside wrapping.

To summarize: test the unexported functions instead of testing the exported ones!

Let's make an example. Say that we have a Slack API struct which has two methods:

• the SendMessage method which sends an HTTP request to a Slack webhook
• the SendDataSynchronously method which given a slice of strings iterates over them and calls SendMessage for every iteration

So in order to test SendDataSynchronously without making an HTTP request each time we would have to mock SendMessage, right?

package main

import (
    "fmt"
)

// URI interface
type URI interface {
    GetURL() string
}

// MessageSender interface
type MessageSender interface {
    SendMessage(message string) error
}

// This one is the "object" that our users will call to use this package functionalities
type API struct {
    baseURL  string
    endpoint string
}

// Here we make API implement implicitly the URI interface
func (api *API) GetURL() string {
    return api.baseURL + api.endpoint
}

// Here we make API implement implicitly the MessageSender interface
// Again we're just WRAPPING the sendMessage function here, nothing fancy 
func (api *API) SendMessage(message string) error {
    return sendMessage(api, message)
}

// We want to test this method but it calls SendMessage which makes a real HTTP request!
// Again we're just WRAPPING the sendDataSynchronously function here, nothing fancy
func (api *API) SendDataSynchronously(data []string) error {
    return sendDataSynchronously(api, data)
}

// this would make a real HTTP request
func sendMessage(uri URI, message string) error {
    fmt.Println("This function won't get called because we will mock it")
    return nil
}

// this is the function we want to test :)
func sendDataSynchronously(sender MessageSender, data []string) error {
    for _, text := range data {
        err := sender.SendMessage(text)

        if err != nil {
            return err
        }
    }

    return nil
}

// TEST CASE BELOW

// Here's our mock which just contains some variables that will be filled for running assertions on them later on
type mockedSender struct {
    err      error
    messages []string
}

// We make our mock implement the MessageSender interface so we can test sendDataSynchronously
func (sender *mockedSender) SendMessage(message string) error {
    // let's store all received messages for later assertions
    sender.messages = append(sender.messages, message)

    return sender.err // return error for later assertions
}

func TestSendsAllMessagesSynchronously() {
    mockedMessages := make([]string, 0)
    sender := mockedSender{nil, mockedMessages}

    messagesToSend := []string{"one", "two", "three"}
    err := sendDataSynchronously(&sender, messagesToSend)

    if err == nil {
        fmt.Println("All good here we expect the error to be nil:", err)
    }

    expectedMessages := fmt.Sprintf("%v", messagesToSend)
    actualMessages := fmt.Sprintf("%v", sender.messages)

    if expectedMessages == actualMessages {
        fmt.Println("Actual messages are as expected:", actualMessages)
    }
}

func main() {
    TestSendsAllMessagesSynchronously()
}

What I like about this approach is that by looking at the unexported methods you can clearly see what the dependencies are. At the same time the API that you export is a lot cleaner and with less parameters to pass along since the true dependency here is just the parent receiver which is implementing all those interfaces itself. Yet every function is potentially depending only on one part of it (one, maybe two interfaces) which makes refactors a lot easier. It's nice to see how your code is really coupled just by looking at the functions signatures, I think it makes a powerful tool against smelling code.

To make things easy I put everything into one file to allow you to run the code in the playground here but I suggest you also check out the full example on GitHub, here is the slack.go file and here the slack_test.go.

And here the whole thing.

You use List#get(int index) to get an object with the index index in the list. You use it like that:

List<ExampleClass> list = new ArrayList<ExampleClass>();
list.add(new ExampleClass());
list.add(new ExampleClass());
list.add(new ExampleClass());
ExampleClass exampleObj = list.get(2); // will get the 3rd element in the list (index 2);

It's not a big deal on a small/personal scale, but it can become a bigger deal quickly on a larger scale. My employer is a large Microsoft shop, but won't/can't buy into Team System/TFS for a number of reasons. We currently use Subversion + Orcas + MBUnit + TestDriven.NET and it works well, but getting TD.NET was a huge hassle. The version sensitivity of MBUnit + TestDriven.NET is also a big hassle, and having one additional commercial thing (TD.NET) for legal to review and procurement to handle and manage, isn't trivial. My company, like a lot of companies, are fat and happy with a MSDN Subscription model, and it's just not used to handling one off procurements for hundreds of developers. In other words, the fully integrated MS offer, while definitely not always best-of-bread, is a significant value-add in my opinion.

I think we'll stay with our current step because it works and we've already gotten over the hump organizationally, but I sure do wish MS had a compelling offering in this space so we could consolidate and simplify our dev stack a bit.

If you want to change MSSQL server language, you can use the following QUERY:

EXEC sp_configure 'default language', 'British English';

it should works at least in pyspark 2.4

tdata = tdata.withColumn("Age",  when((tdata.Age == "") & (tdata.Survived == "0") , "NewValue").otherwise(tdata.Age))

Starting with Spring 4.1, We can directly set the property in application.yml using the @TestPropertySource annotation.

@RunWith(SpringRunner.class)
@SpringBootTest
@TestPropertySource(properties = {"yoursection.yourparameter=your_value"})
public MyIntTest
{
 //your test methods
}

Just convert your yaml parameters into complete property structure. For example: If content of application.yml is like below

yoursection:
  yourparameter:your_value

Then value to go inside the @TestPropertySource will be,

yoursection.yourparameter=your_value

Very old but I have just struggled with this, this is how I solved it in pure xml. In res/values/colors.xml I added three colours (the colour_...);

<resources>

    <color name="black_overlay">#66000000</color>

    <color name="colour_highlight_grey">#ff666666</color>
    <color name="colour_dark_blue">#ff000066</color>
    <color name="colour_dark_green">#ff006600</color>

</resources>

In the res/drawable folder I created listview_colours.xml which contained;

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/colour_highlight_grey" android:state_pressed="true"/>
    <item android:drawable="@color/colour_dark_blue" android:state_selected="true"/>
    <item android:drawable="@color/colour_dark_green" android:state_activated="true"/>
    <item android:drawable="@color/colour_dark_blue" android:state_focused="true"/>
</selector>

In the main_activity.xml find the List View and add the drawable to listSelector;

<ListView
    android:id="@+id/menuList"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:listSelector="@drawable/listview_colours"
    android:background="#ff222222"/>
</LinearLayout>

Play with the state_... items in the listview_colours.xml to get the effect you want.

There is also a method where you can set the style of the List View but I never managed to get it to work

Don't know men. I found the best way for me after testing different ways like 10 minutes. ( Change the numbers in code to get big or small random number.)

    int x;
srand ( time(NULL) );
x = rand() % 1000 * rand() % 10000 ;
cout<<x;

In order to call this you will have to store a reference to your form and pass the reference to the run method. Then you can call this in an actionhandler.

public partial class Form1 : Form
{
    public void ChangeSize(int width, int height)
    {
        this.Size = new Size(width, height);
    }
}

Try this first:

git checkout master

(If you're on a different branch than master, use the branch name there instead.)

If that doesn't work, try...

For a single file:

git checkout HEAD /path/to/file

For the entire repository working copy:

git reset --hard HEAD

And if that doesn't work, then you can look in the reflog to find your old head SHA and reset to that:

git reflog
git reset --hard <sha from reflog>

HEAD is a name that always points to the latest commit in your current branch.

You state in the comments that the returned JSON is this:

{ 
  "dstOffset" : 3600, 
  "rawOffset" : 36000, 
  "status" : "OK", 
  "timeZoneId" : "Australia/Hobart", 
  "timeZoneName" : "Australian Eastern Daylight Time" 
}

You're telling Gson that you have an array of Post objects:

List<Post> postsList = Arrays.asList(gson.fromJson(reader,
                    Post[].class));

You don't. The JSON represents exactly one Post object, and Gson is telling you that.

Change your code to be:

Post post = gson.fromJson(reader, Post.class);

You can convert .csv file to UTF-8 with BOM via Notepad++:

1. Open the file in Notepad++.
2. Go to menu Encoding?Convert to UTF-8.
3. Go to menu File?Save.
4. Close Notepad++.
5. Open the file in Excel .

iOS textTransform support has been added to react-native in 0.56 version. Android textTransform support has been added in 0.59 version. It accepts one of these options:

• none
• uppercase
• lowercase
• capitalize

The actual iOS commit, Android commit and documentation

Example:

<View>
  <Text style={{ textTransform: 'uppercase'}}>
    This text should be uppercased.
  </Text>
  <Text style={{ textTransform: 'capitalize'}}>
    Mixed:{' '}
    <Text style={{ textTransform: 'lowercase'}}>
      lowercase{' '}
    </Text>
  </Text>
</View>

You cannot call a function that requires arguments in a template. Write a template tag or filter instead.

In Python you can use (.)\1{9,}

• (.) makes group from one char (any char)
• \1{9,} matches nine or more characters from 1st group

example:

txt = """1. aaaaaaaaaaaaaaa
2. bb
3. cccccccccccccccccccc
4. dd
5. eeeeeeeeeeee"""
rx = re.compile(r'(.)\1{9,}')
lines = txt.split('\n')
for line in lines:
    rxx = rx.search(line)
    if rxx:
        print line

Output:

1. aaaaaaaaaaaaaaa
3. cccccccccccccccccccc
5. eeeeeeeeeeee

The three constants have similar functions nowadays, but different historical origins, and very occasionally you may be required to use one or the other.

You need to think back to the days of old manual typewriters to get the origins of this. There are two distinct actions needed to start a new line of text:

1. move the typing head back to the left. In practice in a typewriter this is done by moving the roll which carries the paper (the "carriage") all the way back to the right -- the typing head is fixed. This is a carriage return.
2. move the paper up by the width of one line. This is a line feed.

In computers, these two actions are represented by two different characters - carriage return is CR, ASCII character 13, vbCr; line feed is LF, ASCII character 10, vbLf. In the old days of teletypes and line printers, the printer needed to be sent these two characters -- traditionally in the sequence CRLF -- to start a new line, and so the CRLF combination -- vbCrLf -- became a traditional line ending sequence, in some computing environments.

The problem was, of course, that it made just as much sense to only use one character to mark the line ending, and have the terminal or printer perform both the carriage return and line feed actions automatically. And so before you knew it, we had 3 different valid line endings: LF alone (used in Unix and Macintoshes), CR alone (apparently used in older Mac OSes) and the CRLF combination (used in DOS, and hence in Windows). This in turn led to the complications of DOS / Windows programs having the option of opening files in text mode, where any CRLF pair read from the file was converted to a single CR (and vice versa when writing).

So - to cut a (much too) long story short - there are historical reasons for the existence of the three separate line separators, which are now often irrelevant: and perhaps the best course of action in .NET is to use Environment.NewLine which means someone else has decided for you which to use, and future portability issues should be reduced.

If you are actually looking for the index number (and not the value) of the selected option then it would be

document.forms[0].elements["CCards"].selectedIndex 
/* You may need to change document.forms[0] to reference the correct form */

or using jQuery

$('select[name="CCards"]')[0].selectedIndex 

its work

    String json = "{\"phonetype\":\"N95\",\"cat\":\"WP\"}";

    try {

        JSONObject obj = new JSONObject(json);

        Log.d("My App", obj.toString());
        Log.d("phonetype value ", obj.getString("phonetype"));

    } catch (Throwable tx) {
        Log.e("My App", "Could not parse malformed JSON: \"" + json + "\"");
    }

When you "call" a function you are basically just telling the program to execute that function. So if you had a function that added two numbers such as:

def add(a,b):
    return a + b

you would call the function like this:

add(3,5)

which would return 8. You can put any two numbers in the parentheses in this case. You can also call a function like this:

answer = add(4,7)

Which would set the variable answer equal to 11 in this case.

If anyone comes looking to create a similar JSON, just without using cart as an array, here goes:

I have an array of objects myArr as:

var myArr = [{resourceType:"myRT",
            id: 1,
            value:"ha"},
            {resourceType:"myRT",
            id: 2,
            value:"he"},
            {resourceType:"myRT",
            id: 3,
            value:"Li"}];

and I will attempt to create a JSON with the following structure:

{
 "1":{"resourceType":"myRT","id":"1","value":"ha"},
 "2":{"resourceType":"myRT","id":"2","value":"he"},
 "3":{"resourceType":"myRT","id":"3","value":"Li"}
}

you can simply do-

var cart = {};
myArr.map(function(myObj){
                    cart[myObj.id]= myObj;
                    });

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

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

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

  Datagram

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

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

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

The best way, that I found to myself is save array as data string with separator characters

$array = array("value1", "value2", "value3", "...", "valuen");
$array_data = implode("array_separator", $array);

$query = "INSERT INTO my_tbl_name (id, array_data) VALUES(NULL,'" . $array_data . "');";

You can then search data, stored in your array with simple query

$query = "SELECT * FROM my_tbl_name WHERE array_data LIKE '%value3%'";

use explode() function to convert "array_data" string to array

$array = explode("array_separator", $array_data);

note that this is not working with multidimensional arrays and make sure that your "array_separator" is unique and had not exist in array values.

Be careful !!! if you just will take a form data and put in database, you will be in trap, becous the form data isn't SQL-safe ! you must handle your form value with mysql_real_escape_string or if you use MySQLi mysqli::real_escape_string or if value are integer or boolean cast (int) (boolean) on them

$number = (int)$_POST['number'];
$checked = (boolean) $_POST['checked'];

$name = mysql_real_escape_string($db_pt, $_POST['name']);
$email = mysqli_obj->real_escape_string($_POST['email']);

$.ajax("youurl", function(data){
    if (data.success == true)
    setTimeout(function(){window.location = window.location}, 5000); 
    })
)

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

I know there is a more elegant way to do this and I'm open to suggestions... this is what I did:

          try
            {


             // Set directory for list to be made of
                DirectoryInfo jpegInfo = new DirectoryInfo(destinationFolder);
                DirectoryInfo jpgInfo = new DirectoryInfo(destinationFolder);
                DirectoryInfo gifInfo = new DirectoryInfo(destinationFolder);
                DirectoryInfo tiffInfo = new DirectoryInfo(destinationFolder);
                DirectoryInfo bmpInfo = new DirectoryInfo(destinationFolder);

                // Set file type
                FileInfo[] Jpegs = jpegInfo.GetFiles("*.jpeg");
                FileInfo[] Jpgs = jpegInfo.GetFiles("*.jpg");
                FileInfo[] Gifs = gifInfo.GetFiles("*.gif");
                FileInfo[] Tiffs = gifInfo.GetFiles("*.tiff");
                FileInfo[] Bmps = gifInfo.GetFiles("*.bmp");

        //  listBox1.Items.Add(@"");  // Hack for the first list item no preview problem
        // Iterate through each file, displaying only the name inside the listbox...
        foreach (FileInfo file in Jpegs)
        {
                listBox1.Items.Add(file.Name);
                Photo curPhoto = new Photo();
                curPhoto.PhotoLocation = file.FullName;
                metaData.AddPhoto(curPhoto);
            }

          foreach (FileInfo file in Jpgs)
          {
              listBox1.Items.Add(file.Name);
                Photo curPhoto = new Photo();
                curPhoto.PhotoLocation = file.FullName;
                metaData.AddPhoto(curPhoto);
            }
          foreach (FileInfo file in Gifs)
          {
              listBox1.Items.Add(file.Name);
              Photo curPhoto = new Photo();
              curPhoto.PhotoLocation = file.FullName;
              metaData.AddPhoto(curPhoto);
          }
          foreach (FileInfo file in Tiffs)
          {
              listBox1.Items.Add(file.Name);
              Photo curPhoto = new Photo();
              curPhoto.PhotoLocation = file.FullName;
              metaData.AddPhoto(curPhoto);
          }
          foreach (FileInfo file in Bmps)
          {
              listBox1.Items.Add(file.Name);
              Photo curPhoto = new Photo();
              curPhoto.PhotoLocation = file.FullName;
              metaData.AddPhoto(curPhoto);
          }

[Based on Android source code:]

At the C++ side, the SurfaceFlinger implements the captureScreen API. This is exposed over the binder IPC interface, returning each time a new ashmem area that contains the raw pixels from the screen. The actual screenshot is taken through OpenGL.

For the system C++ clients, the interface is exposed through the ScreenshotClient class, defined in <surfaceflinger_client/SurfaceComposerClient.h> for Android < 4.1; for Android > 4.1 use <gui/SurfaceComposerClient.h>

Before JB, to take a screenshot in a C++ program, this was enough:

ScreenshotClient ssc;
ssc.update();

With JB and multiple displays, it becomes slightly more complicated:

ssc.update(
    android::SurfaceComposerClient::getBuiltInDisplay(
        android::ISurfaceComposer::eDisplayIdMain));

Then you can access it:

do_something_with_raw_bits(ssc.getPixels(), ssc.getSize(), ...);

Using the Android source code, you can compile your own shared library to access that API, and then expose it through JNI to Java. To create a screen shot form your app, the app has to have the READ_FRAME_BUFFER permission. But even then, apparently you can create screen shots only from system applications, i.e. ones that are signed with the same key as the system. (This part I still don't quite understand, since I'm not familiar enough with the Android Permissions system.)

Here is a piece of code, for JB 4.1 / 4.2:

#include <utils/RefBase.h>
#include <binder/IBinder.h>
#include <binder/MemoryHeapBase.h>
#include <gui/ISurfaceComposer.h>
#include <gui/SurfaceComposerClient.h>

static void do_save(const char *filename, const void *buf, size_t size) {
    int out = open(filename, O_RDWR|O_CREAT, 0666);
    int len = write(out, buf, size);
    printf("Wrote %d bytes to out.\n", len);
    close(out);
}

int main(int ac, char **av) {
    android::ScreenshotClient ssc;
    const void *pixels;
    size_t size;
    int buffer_index;

    if(ssc.update(
        android::SurfaceComposerClient::getBuiltInDisplay(
            android::ISurfaceComposer::eDisplayIdMain)) != NO_ERROR ){
        printf("Captured: w=%d, h=%d, format=%d\n");
        ssc.getWidth(), ssc.getHeight(), ssc.getFormat());
        size = ssc.getSize();
        do_save(av[1], pixels, size);
    }
    else
        printf(" screen shot client Captured Failed");
    return 0;
}

You will have to split your string into a list of values using split()

So,

lines = text_file.read().split(',')

EDIT: I didn't realise there would be so much traction to this. Here's a more idiomatic approach.

import csv
with open('filename.csv', 'r') as fd:
    reader = csv.reader(fd)
    for row in reader:
        # do something

enum types are called "enumeration types" not because they are containers that "enumerate" values (which they aren't), but because they are defined by enumerating the possible values for a variable of that type.

(Actually, that's a bit more complicated than that - enum types are considered to have an "underlying" integer type, which means each enum value corresponds to an integer value (this is typically implicit, but can be manually specified). C# was designed in a way so that you could stuff any integer of that type into the enum variable, even if it isn't a "named" value.)

The System.Enum.GetNames method can be used to retrieve an array of strings which are the names of the enum values, as the name suggests.

EDIT: Should have suggested the System.Enum.GetValues method instead. Oops.

There should be only one localhost defined, check sites-enabled or nginx.conf.

^ outside of the character class ("[a-zA-Z]") notes that it is the "begins with" operator.
^ inside of the character negates the specified class.

So, "^[a-zA-Z]" translates to "begins with character from a-z or A-Z", and "[^a-zA-Z]" translates to "is not either a-z or A-Z"

Here's a quick reference: http://www.regular-expressions.info/reference.html

If you want to do an ajax call or a simple javascript function, don't forget to close your function with the return false

like this:

function DoAction(id, name) 
{ 
    // your code
    return false;
}

Or

help(list.append)

if you're generally poking around.

building on an answer from another posting.. I've come up with a more generic way to build out a list, utilizing dynamic retrieval with Json.NET version 12.x

using Newtonsoft.Json;

static class JsonObj
{
    /// <summary>
    /// Deserializes a json file into an object list
    /// Author: Joseph Poirier 2/26/2019
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="fileName"></param>
    /// <returns></returns>
    public static List<T> DeSerializeObject<T>(string fileName)
    {
        List<T> objectOut = new List<T>();

        if (string.IsNullOrEmpty(fileName)) { return objectOut; }

        try
        {
            // reading in full file as text
            string ss = File.ReadAllText(fileName);

            // went with <dynamic> over <T> or <List<T>> to avoid error..
            //  unexpected character at line 1 column 2
            var output = JsonConvert.DeserializeObject<dynamic>(ss);

            foreach (var Record in output)
            {
                foreach (T data in Record)
                {
                    objectOut.Add(data);
                }
            }
        }
        catch (Exception ex)
        {
            //Log exception here
            Console.Write(ex.Message);
        }

        return objectOut;
    }
}

call to process

{
        string fname = "../../Names.json"; // <- your json file path

        // for alternate types replace string with custom class below
        List<string> jsonFile = JsonObj.DeSerializeObject<string>(fname);
}

or this call to process

{
        string fname = "../../Names.json"; // <- your json file path

        // for alternate types replace string with custom class below
        List<string> jsonFile = new List<string>();
        jsonFile.AddRange(JsonObj.DeSerializeObject<string>(fname));
}

I had the same issue with a .tgz file .

It was just about the location of the file. Ensure the file is in the same directory of the Dockerfile.

Also ensure the .dockerignore file directory doesn't exclude the file regex pattern.

Put your script after the completion of body tag...it works...

This exception also will be raised whenever a function has been called with the combination of keyword arguments and args, kwargs

Example:

def function(a, b, c, *args, **kwargs):
    print(f"a: {a}, b: {b}, c: {c}, args: {args}, kwargs: {kwargs}")

function(a=1, b=2, c=3, *(4,))

And it'll raise:

TypeError                                 Traceback (most recent call last)
<ipython-input-4-1dcb84605fe5> in <module>
----> 1 function(a=1, b=2, c=3, *(4,))

TypeError: function() got multiple values for argument 'a'

And Also it'll become more complicated, whenever you misuse it in the inheritance. so be careful we this stuff!

1- Calling a function with keyword arguments and args:

class A:
    def __init__(self, a, b, *args, **kwargs):
        self.a = a
        self.b = b
    
class B(A):
    def __init__(self, *args, **kwargs):

        a = 1
        b = 2
        super(B, self).__init__(a=a, b=b, *args, **kwargs)

B(3, c=2)

2- Calling a function with keyword arguments and kwargs which it contains keyword arguments too:

        self.a = a
        self.b = b
    
class B(A):

        a = 1
        b = 2
        super(B, self).__init__(a=a, b=b, *args, **kwargs)

Check my fiddle from this thread: Draw a line connecting two clicked div columns

The layout is different, but basically the idea is to create invisible divs between the boxes and add corresponding borders with jQuery (the answer is only HTML and CSS)

There's a method on the DataGridView called "Sort":

this.dataGridView1.Sort(this.dataGridView1.Columns["Name"], ListSortDirection.Ascending);

This will programmatically sort your datagridview.

I think the problem is with the user having deny privileges. This error comes when the user which you have created does not have the sufficient privileges to access your tables in the database. Do grant the privilege to the user in order to get what you want.

GRANT the user specific permissions such as SELECT, INSERT, UPDATE and DELETE on tables in that database.

From the documentation:

$this->db->insert_id()

The insert ID number when performing database inserts.

Therefore, you could use something like this:

$lastid = $this->db->insert_id();

You can use one of the following.

• $! is the PID of the last backgrounded process.
• kill -0 $PID checks whether it's still running.
• $$ is the PID of the current shell.

Fast and quick solution:

lsof -n -i4TCP:8080

PID is the second field. Then, kill that process:

kill -9 PID

Less fast but permanent solution

1. Go to /usr/local/bin/ (Can use command+shift+g in finder)

2. Make a file named stop. Paste the below code in it:

#!/bin/bash
touch temp.text
lsof -n -i4TCP:$1 | awk '{print $2}' > temp.text
pidToStop=`(sed '2q;d' temp.text)`
> temp.text
if [[ -n $pidToStop ]]
then
kill -9 $pidToStop
echo "Congrates!! $1 is stopped."
else
echo "Sorry nothing running on above port"
fi
rm temp.text

3. Save this file.
4. Make the file executable chmod 755 stop
5. Now, go to terminal and write stop 8888 (or any port)

As many others pointed out if you are trying to add a new element at the end of list then something like, array[array.length-1]=x; should do. But this will replace the existing element.

For something like continuous addition to the array. You can keep track of the index and go on adding elements till you reach end and have the function that does the addition return you the next index, which in turn will tell you how many more elements can fit in the array.

Of course in both the cases the size of array will be predefined. Vector can be your other option since you do not want arraylist, which will allow you all the same features and functions and additionally will take care of incrementing the size.

Coming to the part where you want StringBuffer to array. I believe what you are looking for is the getChars(int srcBegin, int srcEnd,char[] dst,int dstBegin) method. Look into it that might solve your doubts. Again I would like to point out that after managing to get an array out of it, you can still only replace the last existing element(character in this case).

Start your XAMPP server by using:

• {XAMPP}\xampp-control.exe
• {XAMPP}\apache_start.bat

Then you have to use the URI http://localhost/index.html because htdocs is the document root of the Apache server.

If you're getting redirected to http://localhost/xampp/*, then index.php located in the htdocs folder is the problem because index.php files have a higher priority than index.html files. You could temporarily rename index.php.

practical usage:

public string someFunctionThatMayBeCalledWithNullAndReturnsString(int? value)
{
  if (value == null)
  {
    return "bad value";
  }

  return someFunctionThatHandlesIntAndReturnsString(value);
}

Use fgets and strtol,

A pointer to the first character following the integer representation in s is stored in the object pointed by p, if *p is different to \n then you have a bad input.

#include <stdio.h>
#include <stdlib.h>

int main(void) 
{
    char *p, s[100];
    long n;

    while (fgets(s, sizeof(s), stdin)) {
        n = strtol(s, &p, 10);
        if (p == s || *p != '\n') {
            printf("Please enter an integer: ");
        } else break;
    }
    printf("You entered: %ld\n", n);
    return 0;
}

We can't because it's expected/required by our customers.

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

Take it easy using this lib.

https://github.com/rohmanhm/force-boolean

you just need to write a single line

const ForceBoolean = require('force-boolean')

const YOUR_VAR = 'false'
console.log(ForceBoolean(YOUR_VAR)) // it's return boolean false

It's also support for following

 return false if value is number 0
 return false if value is string '0'
 return false if value is string 'false'
 return false if value is boolean false
 return true if value is number 1
 return true if value is string '1'
 return true if value is string 'true'
 return true if value is boolean true

Use Random.nextInt(int).

In your case it would look something like this:

a[i][j] = r.nextInt(101);

I had a similar problem, when I wanted to automatically remove temp files I had created. The solution I came up with was not to use command substitution, but rather to pass the name of the variable, that should take the final result, into the function. E.g.

#! /bin/bash

remove_later=""
new_tmp_file() {
    file=$(mktemp)
    remove_later="$remove_later $file"
    eval $1=$file
}
remove_tmp_files() {
    rm $remove_later
}
trap remove_tmp_files EXIT

new_tmp_file tmpfile1
new_tmp_file tmpfile2

So, in your case that would be:

#!/bin/bash

e=2

function test1() {
  e=4
  eval $1="hello"
}

test1 ret

echo "$ret"
echo "$e"

Works and has no restrictions on the "return value".

Put your div inside another div, apply the border to the outer div with n amount of padding/margin where n is the space you want between them.

You can use EL if you want to work as IF:

<h:outputLabel value="#{row==10? '10' : '15'}"/>

Changing styles or classes:

style="#{test eq testMB.test? 'font-weight:bold' : 'font-weight:normal'}"

class="#{test eq testMB.test? 'divRred' : 'divGreen'}"

FireFox + FireBug is very good for this purpose. For IE there's a developer toolbar which I've never used and intend to use so I cannot provide much feedback.

You can combine the following two commands

cat("\014"); 
cat(rep("\n", 50))

alert( years);

Units can be [seconds, minutes, hours, days, weeks, months, years]

Here is a Javascript version that returns a function that does the rescaling for predetermined source and destination ranges, minimizing the amount of computation that has to be done each time.

// This function returns a function bound to the 
// min/max source & target ranges given.
// oMin, oMax = source
// nMin, nMax = dest.
function makeRangeMapper(oMin, oMax, nMin, nMax ){
    //range check
    if (oMin == oMax){
        console.log("Warning: Zero input range");
        return undefined;
    };

    if (nMin == nMax){
        console.log("Warning: Zero output range");
        return undefined
    }

    //check reversed input range
    var reverseInput = false;
    let oldMin = Math.min( oMin, oMax );
    let oldMax = Math.max( oMin, oMax );
    if (oldMin != oMin){
        reverseInput = true;
    }

    //check reversed output range
    var reverseOutput = false;  
    let newMin = Math.min( nMin, nMax )
    let newMax = Math.max( nMin, nMax )
    if (newMin != nMin){
        reverseOutput = true;
    }

    // Hot-rod the most common case.
    if (!reverseInput && !reverseOutput) {
        let dNew = newMax-newMin;
        let dOld = oldMax-oldMin;
        return (x)=>{
            return ((x-oldMin)* dNew / dOld) + newMin;
        }
    }

    return (x)=>{
        let portion;
        if (reverseInput){
            portion = (oldMax-x)*(newMax-newMin)/(oldMax-oldMin);
        } else {
            portion = (x-oldMin)*(newMax-newMin)/(oldMax-oldMin)
        }
        let result;
        if (reverseOutput){
            result = newMax - portion;
        } else {
            result = portion + newMin;
        }

        return result;
    }   
}

Here is an example of using this function to scale 0-1 into -0x80000000, 0x7FFFFFFF

let normTo32Fn = makeRangeMapper(0, 1, -0x80000000, 0x7FFFFFFF);
let fs = normTo32Fn(0.5);
let fs2 = normTo32Fn(0);

In your specific case you can use the following bash command (bash is the default shell on macOS):

for f in *.png; do echo mv "$f" "${f/_*_/_}"; done

^{Note: If there's a chance that your filenames start with -, place -- before them[1]:
mv -- "$f" "${f/_*_/_}"}

Note: echo is prepended to mv so as to perform a dry run. Remove it to perform actual renaming.

You can run it from the command line or use it in a script.

• "${f/_*_/_}" is an application of bash parameter expansion: the (first) substring matching pattern _*_ is replaced with literal _, effectively cutting the middle token from the name.
• Note that _*_ is a pattern (a wildcard expression, as also used for globbing), not a regular expression (to learn about patterns, run man bash and search for Pattern Matching).

If you find yourself batch-renaming files frequently, consider installing a specialized tool such as the Perl-based rename utility. On macOS you can install it using popular package manager Homebrew as follows:

brew install rename

Here's the equivalent of the command at the top using rename:

rename -n -e 's/_.*_/_/'  *.png

Again, this command performs a dry run; remove -n to perform actual renaming.

• Similar to the bash solution, s/.../.../ performs text substitution, but - unlike in bash - true regular expressions are used.

^{[1] The purpose of special argument --, which is supported by most utilities, is to signal that subsequent arguments should be treated as operands (values), even if they look like options due to starting with -, as Jacob C. notes.}

Use the following regex

^(\+91[\-\s]?)?[0]?(91)?[789]\d{9}$

This will support the following formats:

1. 8880344456
2. +918880344456
3. +91 8880344456
4. +91-8880344456
5. 08880344456
6. 918880344456

You can use this JavaScript\jQuery code:

// Sets active link in Bootstrap menu
// Add this code in a central place used\shared by all pages
// like your _Layout.cshtml in ASP.NET MVC for example
$('a[href="' + this.location.pathname + '"]').parents('li,ul').addClass('active');

It'll set the <a>'s parent <li> and the <li>'s parent <ul> as active.

A simple solution that works!

Original source:

Bootstrap add active class to li

"The operation could not be completed" error can also be caused by a C++ project referencing another project that no longer exists in the solution.

Normally, when you remove a project from a solution, Visual Studio removes any references to it from other projects in the solution.

In my case, however, I was sharing projects between solutions hence a bad project reference managed to sneak in, and deleting the bad references fixed the error.

Using Visual Studio 2012.

I was able to figure it out by following the answer in this thread: https://stackoverflow.com/a/8968495/1543447

Basically, I renamed all values, function names, and element names to different values so they wouldn't conflict - and it worked!

There is something wrong in your setDelimiter() function. You don't want to double quote the delimiters, do you?

public void setDelimiter(String delimiter) {
    char[] c = delimiter.toCharArray();
    this.delimiter = "\\" + c[0] + "\\" + c[1];
    System.out.println("Delimiter string is: " + this.delimiter);
}

However, as other users have said, it's better to use the Pattern.quote() method to escape your delimiter if your requirements permit.

My only doubt would be how applicable this technique would be on multi-byte strings, but if that's not a consideration, then I suspect you're covered. (If in doubt, mb_substr() seems an obviously safe choice.)

However, from a big picture perspective, I have to wonder how often you need to access the 'n'th character in a string for this to be a key consideration.

import random

sourcelist=[]
resultlist=[]

for x in range(100):
    sourcelist.append(x)

for y in sourcelist:
    resultlist.insert(random.randint(0,len(resultlist)),y)

print (resultlist)

Guzzle example:

use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;

$token = 'your_token';

$httpClient = new Client();

$response = $httpClient->get(
    'https://httpbin.org/bearer',
    [
        RequestOptions::HEADERS => [
            'Accept' => 'application/json',
            'Authorization' => 'Bearer ' . $token,
        ]
    ]
);

print_r($response->getBody()->getContents());

What will be cleaner and easier to maintain?

All things being equal, probably JavaFX - the API is much more consistent across components. However, this depends much more on how the code is written rather than what library is used to write it.

And what will be faster to build from scratch?

Highly dependent on what you're building. Swing has more components around for it (3rd party as well as built in) and not all of them have made their way to the newer JavaFX platform yet, so there may be a certain amount of re-inventing the wheel if you need something a bit custom. On the other hand, if you want to do transitions / animations / video stuff then this is orders of magnitude easier in FX.

One other thing to bear in mind is (perhaps) look and feel. If you absolutely must have the default system look and feel, then JavaFX (at present) can't provide this. Not a big must have for me (I prefer the default FX look anyway) but I'm aware some policies mandate a restriction to system styles.

Personally, I see JavaFX as the "up and coming" UI library that's not quite there yet (but more than usable), and Swing as the borderline-legacy UI library that's fully featured and supported for the moment, but probably won't be so much in the years to come (and therefore chances are FX will overtake it at some point.)

The best way to do it is

If you can't update configuration files but control the code that handles file uploads use HttpContext.Current.Request.GetBufferlessInputStream(true).

The true value for disableMaxRequestLength parameter tells the framework to ignore configured request limits.

My first thought was to write a single query, but you said that was not possible because one is run by the user and the other is run in the background. How are you storing the list of ids to pass from the user to the background process? Why not put them in a temporary table with a column to signify the order.

So how about this:

1. The user interface bit runs and inserts values into a new table you create. It would insert the id, position and some sort of job number identifier)
2. The job number is passed to the background process (instead of all the ids)
3. The background process does a select from the table in step 1 and you join in to get the other information that you require. It uses the job number in the WHERE clause and orders by the position column.
4. The background process, when finished, deletes from the table based on the job identifier.

It seems that the idiomatic way to do this is to provide a close() method (or similar), and call it explicitely.

You don't need to use .html(). You should go with .val().

From the doc of .val():

The .val() method is primarily used to get the values of form elements such as input, select and textarea. When called on an empty collection, it returns undefined.

var message = $('#message').val();

AJAX requests are asynchronous. Your doSomething function is being exectued, the AJAX request is being made but it happens asynchronously; so the remainder of doSomething is executed and the value of status is undefined when it is returned.

Effectively, your code works as follows:

function doSomething(someargums) {
     return status;
}

var response = doSomething();

And then some time later, your AJAX request is completing; but it's already too late

You need to alter your code, and populate the "response" variable in the "success" callback of your AJAX request. You're going to have to delay using the response until the AJAX call has completed.

Where you previously may have had

var response = doSomething();

alert(response);

You should do:

function doSomething() {  
    $.ajax({
           url:'action.php',
           type: "POST",
           data: dataString,
           success: function (txtBack) { 
            alert(txtBack);
           })
    }); 
};

You don't need to specify the module path per se. CMake ships with its own set of built-in find_package scripts, and their location is in the default CMAKE_MODULE_PATH.

The more normal use case for dependent projects that have been CMakeified would be to use CMake's external_project command and then include the Use[Project].cmake file from the subproject. If you just need the Find[Project].cmake script, copy it out of the subproject and into your own project's source code, and then you won't need to augment the CMAKE_MODULE_PATH in order to find the subproject at the system level.

For smaller font, I use

ax1.set_xticklabels(xticklabels, fontsize=7)

and it works!

Here's a compact way to do something different in all four cases:

if(empty($youtube)) {
    if(empty($link)) {
        # both empty
    } else {
        # only $youtube not empty
    }
} else {
    if(empty($link)) {
        # only $link empty
    } else {
        # both not empty
    }
}

If you want to use an expression instead, you can use ?: instead:

echo empty($youtube) ? ( empty($link) ? 'both empty' : 'only $youtube not empty' )
                     : ( empty($link) ? 'only $link empty' : 'both not empty' );

There are two commands which will work in this situation,

root>git reset --hard HEAD~1

root>git push -f

I think it's a pretty strong assumption to assume that the object is a class. What if it's not a class? There's also the assumption that the object was not defined in the interpreter. What if it was defined in the interpreter? Also, what if the attributes were added dynamically? When some python objects have attributes added to their __dict__ after creation, pickle doesn't respect the addition of those attributes (i.e. it 'forgets' they were added -- because pickle serializes by reference to the object definition).

In all these cases, pickle and cPickle can fail you horribly.

If you are looking to save an object (arbitrarily created), where you have attributes (either added in the object definition, or afterward)… your best bet is to use dill, which can serialize almost anything in python.

We start with a class…

It works. The reason pickle fails, and dill doesn't, is that dill treats __main__ like a module (for the most part), and also can pickle class definitions instead of pickling by reference (like pickle does). The reason dill can pickle a lambda is that it gives it a name… then pickling magic can happen.

Actually, there's an easier way to save all these objects, especially if you have a lot of objects you've created. Just dump the whole python session, and come back to it later.

The only major drawback is that dill is not part of the python standard library. So if you can't install a python package on your server, then you can't use it.

However, if you are able to install python packages on your system, you can get the latest dill with git+https://github.com/uqfoundation/dill.git@master#egg=dill. And you can get the latest released version with pip install dill.

Adding a follow-up to Bill's recommendation for using libcurl: great suggestion, and to be updated:
after 3 years, the curl_escape function is deprecated, so for future use it's better to use curl_easy_escape.

If you are using fish as your shell, the best solution is to create a function. As an example, given the original question, you could copy the 4 lines below and paste them into your fish command line:

function proj
   cd /home/tree/projects/java
end
funcsave proj

This will create the function and save it for use later. If your project changes, just repeat the process using the new path.

If you prefer, you can manually add the function file by doing the following:

nano ~/.config/fish/functions/proj.fish

and enter the text:

function proj
   cd /home/tree/projects/java
end

and finally press ctrl+x to exit and y followed by return to save your changes.

(NOTE: the first method of using funcsave creates the proj.fish file for you).

To run Anaconda Prompt using icon, I made an icon and put

%windir%\System32\cmd.exe "/K" C:\ProgramData\Anaconda3\Scripts\activate.bat C:\ProgramData\Anaconda3 The file location would be different in each computer.

at icon -> right click -> Property -> Shortcut -> Target

I see %HOMEPATH% at icon -> right click -> Property -> Start in

OS: Windows 10, Library: Anaconda 10 (64 bit)

See here for starting the service and here for how to make it permanent. In short to test it, open a "DOS" terminal with administrator privileges and write:

Basically, yes. You write alert('<?php echo($phpvariable); ?>');

There are sure other ways to interoperate, but none of which i can think of being as simple (or better) as the above.

Creating a StopWatch function constructor.

Define 4 local variables

1. startTime
2. endTime
3. isRunning
4. duration set to 0

Next create 3 methods

1. start
2. stop
3. reset

start method

• check if isRunning is true if so throw an error that start cannot be called twice.
• set isRunning to true
• assign the current Date object to startTime.

stop method

• check if isRunning is false if so throw an error that stop cannot be called twice.
• set isRunning to false
• assign the current Date object to endTime.
• calculate the seconds by endTime and startTime Date object
• increment duration with seconds

reset method:

• reset all the local variables.

Read-only property

if you want to access the duration local variable you need to define a property using Object.defineProperty. It's useful when you want to create a read-only property.

Object.defineProperty takes 3 parameters

• the object which to define a property (in this case the current object (this))
• the name of the property

• the value of the key property.

• We want to create a Read-only property so we pass an object as a value. The object contain a get method that return the duration local variable. in this way we cannot change the property only get it.

The trick is to use Date() object to calculate the time.

Reference the code below

function StopWatch() {


let startTime,
    endTime,
    isRunning,
    duration = 0;

  this.start = function () {
    if (isRunning) throw new Error("StopWatch has already been started.");

    isRunning = true;

    startTime = new Date();
  };



this.stop = function () {
    if (!isRunning) throw new Error("StopWatch has already been stop.");

    isRunning = false;

    endTime = new Date();

    const seconds = (endTime.getTime() - startTime.getTime()) / 1000;
    duration += seconds;
  };

  this.reset = function () {
    duration = 0;
    startTime = null;
    endTime = null;
    isRunning = false;
  };

  Object.defineProperty(this, "duration", {
    get: function () {
      return duration;
    },
  });
}

const sw = new StopWatch();

If you are on a system where netstat is not available (e.g. RHEL 7 and more recent Debian releases) you can use ss, as below:

sudo ss -tlpn | grep mysql

And you'll get something like the following for output:

LISTEN     0      50        *:3306        *:*        users:(("mysqld",pid=5307,fd=14))

The fourth column is Local Address:Port. So in this case Mysql is listening on port 3306, the default.

You should use small caps "or" and "and" instead of OR and AND.

And beware also the spaces/tabs between keywords and arguments (you need at least two spaces).

Here is a code sample with your three keywords working fine:

Here is the file ts.txt:

  *** test cases ***
  mytest
    ${color} =  set variable  Red
    Run Keyword If  '${color}' == 'Red'  log to console  \nexecuted with single condition
    Run Keyword If  '${color}' == 'Red' or '${color}' == 'Blue' or '${color}' == 'Pink'  log to console  \nexecuted with multiple or

    ${color} =  set variable  Blue
    ${Size} =  set variable  Small
    ${Simple} =  set variable  Simple
    ${Design} =  set variable  Simple
    Run Keyword If  '${color}' == 'Blue' and '${Size}' == 'Small' and '${Design}' != '${Simple}'  log to console  \nexecuted with multiple and

    ${Size} =  set variable  XL
    ${Design} =  set variable  Complicated
    Run Keyword Unless  '${color}' == 'Black' or '${Size}' == 'Small' or '${Design}' == 'Simple'  log to console  \nexecuted with unless and multiple or

and here is what I get when I execute it:

$ pybot ts.txt
==============================================================================
Ts
==============================================================================
mytest                                                                .
executed with single condition
executed with multiple or
executed with unless and multiple or
mytest                                                                | PASS |

An Application pool is a collection of applications which uses the same worker process of IIS (w3wp.exe). Primary concern of using Application pool is to isolate two different applications with different security concerns and also to avoid crashing of applications due to worker process death.

I just restarted Visual Studio and did IISRESET which solved the problem.

Intercept the KeyPressed event is in my opinion a good solid solution. Pay attention to trigger code characters (e.KeyChar lower then 32) if you use a RegExp.

But in this way is still possible to inject characters out of range whenever the user paste text from the clipboard. Unfortunately I did not found correct clipboard events to fix this.

So a waterproof solution is to intercept TextBox.TextChanged. Here is sometimes the original out of range character visible, for a short time. I recommend to implement both.

using System.Text.RegularExpressions;

private void Form1_Shown(object sender, EventArgs e)
{
    filterTextBoxContent(textBox1);
}


string pattern = @"[^0-9^+^\-^/^*^(^)]";

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    if(e.KeyChar >= 32 && Regex.Match(e.KeyChar.ToString(), pattern).Success) { e.Handled = true; }
}

private void textBox1_TextChanged(object sender, EventArgs e)
{
    filterTextBoxContent(textBox1);
}

private bool filterTextBoxContent(TextBox textBox)
{
    string text = textBox.Text;

    MatchCollection matches = Regex.Matches(text, pattern);
    bool matched = false;

    int selectionStart = textBox.SelectionStart;
    int selectionLength = textBox.SelectionLength;

    int leftShift = 0;
    foreach (Match match in matches)
    {
        if (match.Success && match.Captures.Count > 0)
        {
            matched = true;
            Capture capture = match.Captures[0];

            int captureLength = capture.Length;
            int captureStart = capture.Index - leftShift;
            int captureEnd = captureStart + captureLength;

            int selectionEnd = selectionStart + selectionLength;

            text = text.Substring(0, captureStart) + text.Substring(captureEnd, text.Length - captureEnd);

            textBox.Text = text;

            int boundSelectionStart = selectionStart < captureStart ? -1 : (selectionStart < captureEnd ? 0 : 1);
            int boundSelectionEnd = selectionEnd < captureStart ? -1 : (selectionEnd < captureEnd ? 0 : 1);

            if (boundSelectionStart == -1)
            {
                if (boundSelectionEnd == 0)
                {
                    selectionLength -= selectionEnd - captureStart;
                }
                else if (boundSelectionEnd == 1)
                {
                    selectionLength -= captureLength;
                }
            }
            else if (boundSelectionStart == 0)
            {
                if (boundSelectionEnd == 0)
                {
                    selectionStart = captureStart;
                    selectionLength = 0;
                }
                else if (boundSelectionEnd == 1)
                {
                    selectionStart = captureStart;
                    selectionLength -= captureEnd - selectionStart;
                }
            }
            else if (boundSelectionStart == 1)
            {
                selectionStart -= captureLength;
            }

            leftShift++;
        }
    }

    textBox.SelectionStart = selectionStart;
    textBox.SelectionLength = selectionLength;

    return matched;
}

After the initial panic of accidentally deleting all my files, I used the following to get my data back

git reset HEAD@{1}         
git fsck --lost-found      
git show 
git revert <sha that deleted the files>

You can try like:

   $("#myformid").submit(function(){
        //perform anythng
   });

Or even you can try like

$(".nextbutton").click(function() { 
    $('#form1').submit();
});

An output reg foo is just shorthand for output foo_wire; reg foo; assign foo_wire = foo. It's handy when you plan to register that output anyway. I don't think input reg is meaningful for module (perhaps task). input wire and output wire are the same as input and output: it's just more explicit.

Work 100% sure try this code for the get all hashmap key and value

static HashMap<String, String> map = new HashMap<>();

map.put("one"  " a " );
map.put("two"  " b " );
map.put("three"  " c " );
map.put("four"  " d " );

just call this method whenever you want to show the HashMap value

 private void ShowHashMapValue() {

        /**
         * get the Set Of keys from HashMap
         */
        Set setOfKeys = map.keySet();

/**
 * get the Iterator instance from Set
 */
        Iterator iterator = setOfKeys.iterator();

/**
 * Loop the iterator until we reach the last element of the HashMap
 */
        while (iterator.hasNext()) {
/**
 * next() method returns the next key from Iterator instance.
 * return type of next() method is Object so we need to do DownCasting to String
 */
            String key = (String) iterator.next();

/**
 * once we know the 'key', we can get the value from the HashMap
 * by calling get() method
 */
            String value = map.get(key);

            System.out.println("Key: " + key + ", Value: " + value);
        }
    } 

I had issue with the solutions mentioned above as specifying the string key would give me javax.el.PropertyNotFoundException. The code shown below worked for me. In this I used status to count the index of for each loop and displayed the value of index I am interested on

<c:forEach items="${requestScope.key}"  var="map" varStatus="status" >
    <c:if test="${status.index eq 1}">
        <option><c:out value=${map.value}/></option>
    </c:if>
</c:forEach>    

Whilst this isn't strictly an answer to this question I think it's useful.

Arrays and Collections can bother be converted to Iterable which can avoid the need for performing a hard conversion.

For instance I wrote this to join lists/arrays of stuff into a string with a seperator

public static <T> String join(Iterable<T> collection, String delimiter) {
    Iterator<T> iterator = collection.iterator();
    if (!iterator.hasNext())
        return "";

    StringBuilder builder = new StringBuilder();

    T thisVal = iterator.next();
    builder.append(thisVal == null? "": thisVal.toString());

    while (iterator.hasNext()) {
        thisVal = iterator.next();
        builder.append(delimiter);
        builder.append(thisVal == null? "": thisVal.toString());
    }

    return builder.toString();
}

Using iterable means you can either feed in an ArrayList or similar aswell as using it with a String... parameter without having to convert either.

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

Here is a dplyr solution

Censor_consistently <-  function(x){
  str_replace(x, '^\\s*([<>])\\s*(\\d+)', '\\1\\2')
}


test_df <- tibble(x = c('0.001', '<0.002', ' < 0.003', ' >  100'),  y = 4:1)

mutate_all(test_df, funs(Censor_consistently))

We need to do the following changes/fixes in our earlier onActivityResult()'s gallery picker code to run seamlessly on Android 4.4 (KitKat) and on all other earlier versions as well.

Uri selectedImgFileUri = data.getData();

if (selectedImgFileUri == null ) {

    // The user has not selected any photo
}

try {

   InputStream input = mActivity.getContentResolver().openInputStream(selectedImgFileUri);
   mSelectedPhotoBmp = BitmapFactory.decodeStream(input);
}
catch (Throwable tr) {

    // Show message to try again
}

What you want is maxlength.

Valid for text, search, url, tel, email, and password, it defines the maximum number of characters (as UTF-16 code units) the user can enter into the field. This must be an integer value 0 or higher. If no maxlength is specified, or an invalid value is specified, the field has no maximum length. This value must also be greater than or equal to the value of minlength.

You might consider using one of these input types.

With the help of regular expression also we can achieve.

(/keyword/i).test(source)

/i is for ignore case. If not necessary we can ignore and test for NOT case sensitive match like

(/keyword/).test(source)

The problem is that variables declared in one case are still visible in the subsequent cases unless an explicit { } block is used, but they will not be initialized because the initialization code belongs to another case.

In the following code, if foo equals 1, everything is ok, but if it equals 2, we'll accidentally use the i variable which does exist but probably contains garbage.

switch(foo) {
  case 1:
    int i = 42; // i exists all the way to the end of the switch
    dostuff(i);
    break;
  case 2:
    dostuff(i*2); // i is *also* in scope here, but is not initialized!
}

Wrapping the case in an explicit block solves the problem:

switch(foo) {
  case 1:
    {
        int i = 42; // i only exists within the { }
        dostuff(i);
        break;
    }
  case 2:
    dostuff(123); // Now you cannot use i accidentally
}

Edit

To further elaborate, switch statements are just a particularly fancy kind of a goto. Here's an analoguous piece of code exhibiting the same issue but using a goto instead of a switch:

int main() {
    if(rand() % 2) // Toss a coin
        goto end;

    int i = 42;

  end:
    // We either skipped the declaration of i or not,
    // but either way the variable i exists here, because
    // variable scopes are resolved at compile time.
    // Whether the *initialization* code was run, though,
    // depends on whether rand returned 0 or 1.
    std::cout << i;
}

Perl doesn't have a native boolean type, but you can use comparison of integers or strings in order to get the same behavior. Alan's example is a nice way of doing that using comparison of integers. Here's an example

my $boolean = 0;
if ( $boolean ) {
    print "$boolean evaluates to true\n";
} else {
    print "$boolean evaluates to false\n";
}

One thing that I've done in some of my programs is added the same behavior using a constant:

#!/usr/bin/perl

use strict;
use warnings;

use constant false => 0;
use constant true  => 1;

my $val1 = true;
my $val2 = false;

print $val1, " && ", $val2;
if ( $val1 && $val2 ) {
    print " evaluates to true.\n";
} else {
    print " evaluates to false.\n";
}

print $val1, " || ", $val2;
if ( $val1 || $val2 ) {
    print " evaluates to true.\n";
} else {
    print " evaluates to false.\n";
}

The lines marked in "use constant" define a constant named true that always evaluates to 1, and a constant named false that always evaluates by 0. Because of the way that constants are defined in Perl, the following lines of code fails as well:

true = 0;
true = false;

The error message should say something like "Can't modify constant in scalar assignment."

I saw that in one of the comments you asked about comparing strings. You should know that because Perl combines strings and numeric types in scalar variables, you have different syntax for comparing strings and numbers:

my $var1 = "5.0";
my $var2 = "5";

print "using operator eq\n";
if ( $var1 eq $var2 ) {
    print "$var1 and $var2 are equal!\n";
} else {
    print "$var1 and $var2 are not equal!\n";
}

print "using operator ==\n";
if ( $var1 == $var2 ) {
    print "$var1 and $var2 are equal!\n";
} else {
    print "$var1 and $var2 are not equal!\n";
}

The difference between these operators is a very common source of confusion in Perl.

Why not use the API?

int h = 48; // height in pixels
int w = 48; // width in pixels    
Bitmap scaled = Bitmap.createScaledBitmap(largeBitmap, w, h, true);

You can do two different container one with mobile order and hide on desktop screen, another with desktop order and hide on mobile screen

private void DeleteProductButton_Click(object sender, EventArgs e)
{


    string ProductID = deleteProductButton.Text;
    if (string.IsNullOrEmpty(ProductID))
    {
        MessageBox.Show("Please enter valid ProductID");
        deleteProductButton.Focus();
    }
    try
    {
        string SelectDelete = "Delete from Products where ProductID=" + deleteProductButton.Text;
        SqlCommand command = new SqlCommand(SelectDelete, Conn);
        command.CommandType = CommandType.Text;
        command.CommandTimeout = 15;

        DialogResult comfirmDelete = MessageBox.Show("Are you sure you want to delete this record?");
        if (comfirmDelete == DialogResult.No)
        {
            return;
        }
    }
    catch (Exception Ex)
    {
        MessageBox.Show(Ex.Message);

    }
}

You can change using the .bat make sure you run the call command prior, hopefully this helps anyone in future making similar .bat commands

This worked. The first row had column names in it.

FWIW, in Boostrap 4.4, you can add .text-wrap style to things like buttons:

   <a href="#" class="btn btn-primary text-wrap">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>

https://getbootstrap.com/docs/4.4/utilities/text/#text-wrapping-and-overflow

I found a solution wich is to do:

<span class="visible-sm"> your code without col </span>
<span class="visible-xs"> your code with col </span>

It's not very optimized but it works. Did you find something better? It really miss a class like col-sm-0 to apply colons just to the xs size...

WebElement drop_down =driver.findElement(By.id("Category"));
Select se = new Select(drop_down);
for(int i=0 ;i<se.getOptions().size(); i++)
System.out.println(se.getOptions().get(i).getAttribute("value"));

This fixed my issue:

Go to terminal shell and type mongo.

Then type use db_name.

Then type:

 db.createUser(
   {
     user: "mongodb",
     pwd: "dogmeatsubparflavour1337",
     roles: [ { role: "dbOwner", db: "db_name" } ]
   }
 )

Also try: db.getUsers()

Quick sample:

const MongoClient = require('mongodb').MongoClient;

// MongoDB Connection Info
const url = 'mongodb://mongodb:[email protected]:27017/?authMechanism=DEFAULT&authSource=db_name';
// Additional options: https://docs.mongodb.com/manual/reference/connection-string/#connection-string-options

// Use Connect Method to connect to the Server
MongoClient.connect(url)
  .then((db) => {
    console.log(db);
    console.log('Casually connected correctly to server.');
    // Be careful with db.close() when working asynchronously
    db.close();
  })
  .catch((error) => {
    console.log(error);
  });

echo "<script>
window.location.href='admin/ahm/panel';
alert('There are no fields to generate a report');
</script>";

Try out this way it works...

First assign the window with the new page where the alert box must be displayed then show the alert box.

Different Idea:

(1) You save the original file as a variable.

(2) You overwrite the original file with new information.

(3) You append the original file in the data below the new information.

Code:

with open(<filename>,'r') as contents:
      save = contents.read()
with open(<filename>,'w') as contents:
      contents.write(< New Information >)
with open(<filename>,'a') as contents:
      contents.write(save)

If you find any ... let me know!

Seriously, as Josh Smith points out in this post, it's amazing there isn't a CodePlex community or something for this. Heck, it is amazing that there aren't more for purchase!

The only one that I have found (for sale) is reuxables. A little pricey, if you ask me, but you do get 9 themes/61 variations.

UPDATE 1:

After I posted my answer, I thought, heck, I should go see if any CodePlex project exists for this already. I didn't find any specific project just for themes, but I did discover the WPF Contrib project ... which does have 1 theme that they never released.

UPDATE 2:

Rudi Grobler (above) just created CodePlex community for this ... starting with converted themes he mentions above. See his blog post for more info. Way to go Rudi!

UPDATE 3:

As another answer below has mentioned, since this question and my answer were written, the WPF Toolkit has incorporated some free themes, in particular, the themes from the Silverlight Toolkit. Rudi's project goes a little further and adds several more ... but depending on your situation, the WPF Toolkit might be all you need (and you might be installing it already).

Try a different port if you can't find any current running processes or killing them doesn't work. For example, try 27018 because the default is 27017.

mongod  --port 27018

I found this out with the command, mongod --help

I had the same issue.For me the problem was how to configure a cache limit to images.And i came across this site which gave some insights to the procedure on how the issue can be handled.Hope it will be helpful for you too Link:[https://varvy.com/pagespeed/cache-control.html]

$('body').click(function(){ alert('test' )})

var foo = $.data( $('body').get(0), 'events' ).click
// you can query $.data( object, 'events' ) and get an object back, then see what events are attached to it.

$.each( foo, function(i,o) {
    alert(i) // guid of the event
    alert(o) // the function definition of the event handler
});

You can inspect by feeding the object reference ( not the jQuery object though ) to $.data, and for the second argument feed 'events' and that will return an object populated with all the events such as 'click'. You can loop through that object and see what the event handler does.

By using below method you can convert java.math.BigDecimal to String.

   BigDecimal bigDecimal = new BigDecimal("10.0001");
   String bigDecimalString = String.valueOf(bigDecimal.doubleValue());
   System.out.println("bigDecimal value in String: "+bigDecimalString);

Output:
bigDecimal value in String: 10.0001

Try using

unset($v)

It seems the only time a variable is not set is when it is specifically unset($v). It sounds like your meaning of 'existence' is different than PHP's definition. NULL is certainly existing, it is NULL.

Use these:

webview.getSettings().setBuiltInZoomControls(true);
webview.getSettings().setDisplayZoomControls(false);

if you decide to use http://compass-style.org/, a sass-based css framework, it provides very useful darken() and lighten() sass functions to dynamically generate css. it's very clean:

@import compass/utilities

$link_color: #bb8f8f
a
  color: $link_color
a:visited
  color: $link_color
a:hover
  color: darken($link_color,10)

generates

a {
  color: #bb8f8f;
}

a:visited {
  color: #bb8f8f;
}

a:hover {
  color: #a86f6f;
}

OK so I think i know the issue you're having.

Basically, because Composer can't see the migration files you are creating, you are having to run the dump-autoload command which won't download anything new, but looks for all of the classes it needs to include again. It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php), and this is why your migration is working after you run that command.

How to fix it (possibly) You need to add some extra information to your composer.json file.

"autoload": {
    "classmap": [
        "PATH TO YOUR MIGRATIONS FOLDER"
    ],
}

You need to add the path to your migrations folder to the classmap array. Then run the following three commands...

php artisan clear-compiled 
composer dump-autoload
php artisan optimize

This will clear the current compiled files, update the classes it needs and then write them back out so you don't have to do it again.

Ideally, you execute composer dump-autoload -o , for a faster load of your webpages. The only reason it is not default, is because it takes a bit longer to generate (but is only slightly noticable).

Hope you can manage to get this sorted, as its very annoying indeed :(

private int compareLists(List<String> list1, List<String> list2){
    Collections.sort(list1);
    Collections.sort(list2);

    int maxIteration = 0;
    if(list1.size() == list2.size() || list1.size() < list2.size()){
        maxIteration = list1.size();
    } else {
        maxIteration = list2.size();
    }

    for (int index = 0; index < maxIteration; index++) {
        int result = list1.get(index).compareTo(list2.get(index));
        if (result == 0) {
            continue;
        } else {
            return result;
        }
    }
    return list1.size() - list2.size();
}

Just use it as you would a non-concurrent collection. The Concurrent[Collection] classes wrap the regular collections so that you don't have to think about synchronizing access.

Edit: ConcurrentLinkedList isn't actually just a wrapper, but rather a better concurrent implementation. Either way, you don't have to worry about synchronization.

This is an interesting question and since it isn't explained very explicitly in the documentation I'll answer this by going through the sourcecode of mod_rewrite; demonstrating a big benefit of open-source.

In the top section you'll quickly spot the defines used to name these flags:

#define CONDFLAG_NONE               1<<0
#define CONDFLAG_NOCASE             1<<1
#define CONDFLAG_NOTMATCH           1<<2
#define CONDFLAG_ORNEXT             1<<3
#define CONDFLAG_NOVARY             1<<4

and searching for CONDFLAG_ORNEXT confirms that it is used based on the existence of the [OR] flag:

else if (   strcasecmp(key, "ornext") == 0
         || strcasecmp(key, "OR") == 0    ) {
    cfg->flags |= CONDFLAG_ORNEXT;
}

The next occurrence of the flag is the actual implementation where you'll find the loop that goes through all the RewriteConditions a RewriteRule has, and what it basically does is (stripped, comments added for clarity):

# loop through all Conditions that precede this Rule
for (i = 0; i < rewriteconds->nelts; ++i) {
    rewritecond_entry *c = &conds[i];

    # execute the current Condition, see if it matches
    rc = apply_rewrite_cond(c, ctx);

    # does this Condition have an 'OR' flag?
    if (c->flags & CONDFLAG_ORNEXT) {
        if (!rc) {
            /* One condition is false, but another can be still true. */
            continue;
        }
        else {
            /* skip the rest of the chained OR conditions */
            while (   i < rewriteconds->nelts
                   && c->flags & CONDFLAG_ORNEXT) {
                c = &conds[++i];
            }
        }
    }
    else if (!rc) {
        return 0;
    }
}

You should be able to interpret this; it means that OR has a higher precedence, and your example indeed leads to if ( (A OR B) AND (C OR D) ). If you would, for example, have these Conditions:

RewriteCond A [or]
RewriteCond B [or]
RewriteCond C
RewriteCond D

it would be interpreted as if ( (A OR B OR C) and D ).

$("tr.item").each(function() {
  $this = $(this);
  var value = $this.find("span.value").html();
  var quantity = $this.find("input.quantity").val();
});

Windows Service runs using a local system account.It can start automatically as the user logs into the system or it can be started manually.However, a windows service say BST can be run using a particular user account on the machine.This can be done as follows:start services.msc and go to the properties of your windows service,BST.From there you can give the login parameters of the required user.Service then runs with that user account and no other user can run that service.

In my case, Angular 6, I renamed folder and file names of my modules from google.map.module.ts to google-map.module.ts. In order to compile without overlay with old module and component names, ng compiler compiled with no error.

In app.routes.ts:

     {
        path: 'calendar', 
        loadChildren: './views/app-calendar/app-calendar.module#AppCalendarModule', 
        data: { title: 'Calendar', breadcrumb: 'CALENDAR'}
      },

In google-map.routing.ts

import { GoogleMapComponent } from './google-map.component';
const routes: Routes = [
  {
    path: '', component: GoogleMapComponent, data: { title: 'Coupon Map' }
  }
];
@NgModule({
    exports: [RouterModule],
    imports: [RouterModule.forChild(routes)]
})
export class GoogleMapRoutingModule { }

In google-map.module.ts:

import { GoogleMapRoutingModule } from './google-map.routing';
@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    CommonModule,
    GoogleMapRoutingModule,
  ],
  exports: [GoogleMapComponent],
  declarations: [GoogleMapComponent]
})
export class GoogleMapModule { }

Put the select statement in a dynamic PL/SQL block.

Yay recursion!

def trunc(s,l):
    if l > 0:
        return s[:l] + trunc(s, l - len(s))
    return ''

Won't scale forever, but it's fine for smaller strings. And it's pretty.

I admit I just read the Little Schemer and I like recursion right now.

if x is numeric, then add scale_x_continuous(); if x is character/factor, then add scale_x_discrete(). This might solve your problem.

It seems that in VBA macro code for an ActiveX checkbox control you use

If (ActiveSheet.OLEObjects("CheckBox1").Object.Value = True)

and for a Form checkbox control you use

If (ActiveSheet.Shapes("CheckBox1").OLEFormat.Object.Value = 1)

If you don't care if the code within the timer may take longer than your interval, use setInterval():

setInterval(function, delay)

That fires the function passed in as first parameter over and over.

A better approach is, to use setTimeout along with a self-executing anonymous function:

(function(){
    // do some stuff
    setTimeout(arguments.callee, 60000);
})();

that guarantees, that the next call is not made before your code was executed. I used arguments.callee in this example as function reference. It's a better way to give the function a name and call that within setTimeout because arguments.callee is deprecated in ecmascript 5.

@p4bloch if you want to capture results from a series of capture parentheses, then you need to use the rangeAtIndex(index) method of NSTextCheckingResult, instead of range. Here's @MartinR 's method for Swift2 from above, adapted for capture parentheses. In the array that is returned, the first result [0] is the entire capture, and then individual capture groups begin from [1]. I commented out the map operation (so it's easier to see what I changed) and replaced it with nested loops.

func matches(for regex: String!, in text: String!) -> [String] {

    do {
        let regex = try NSRegularExpression(pattern: regex, options: [])
        let nsString = text as NSString
        let results = regex.matchesInString(text, options: [], range: NSMakeRange(0, nsString.length))
        var match = [String]()
        for result in results {
            for i in 0..<result.numberOfRanges {
                match.append(nsString.substringWithRange( result.rangeAtIndex(i) ))
            }
        }
        return match
        //return results.map { nsString.substringWithRange( $0.range )} //rangeAtIndex(0)
    } catch let error as NSError {
        print("invalid regex: \(error.localizedDescription)")
        return []
    }
}

An example use case might be, say you want to split a string of title year eg "Finding Dory 2016" you could do this:

print ( matches(for: "^(.+)\\s(\\d{4})" , in: "Finding Dory 2016"))
// ["Finding Dory 2016", "Finding Dory", "2016"]

From the jQuery documentation - http://api.jquery.com/jQuery.ajax/

contentType When sending data to the server, use this content type.

dataType The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response

"text": A plain text string.

So you want contentType to be application/json and dataType to be text:

$.ajax({
    type : "POST",
    url : /v1/user,
    dataType : "text",
    contentType: "application/json",
    data : dataAttribute,
    success : function() {

    },
    error : function(error) {

    }
});

works at Swift 5

    do {
        let documentDirectory = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
        let fileUrl = documentDirectory.appendingPathComponent("userInfo").appendingPathExtension("sqlite3")
        if FileManager.default.fileExists(atPath: fileUrl.path) {
            print("FILE AVAILABLE")
        } else {
            print("FILE NOT AVAILABLE")
        }
    } catch {
        print(error)
    }

where "userInfo" - file's name, and "sqlite3" - file's extension

Configure NLog via XML, but Programmatically

What? Did you know that you can specify the NLog XML directly to NLog from your app, as opposed to having NLog read it from the config file? Well, you can. Let's say that you have a distributed app and you want to use the same configuration everywhere. You could keep a config file in each location and maintain it separately, you could maintain one in a central location and push it out to the satellite locations, or you could probably do a lot of other things. Or, you could store your XML in a database, get it at app startup, and configure NLog directly with that XML (maybe checking back periodically to see if it had changed).

  string xml = @"<nlog>
                   <targets>
                     <target name='console' type='Console' layout='${message}' />
                   </targets>

                   <rules>
                     <logger name='*' minlevel='Error' writeTo='console' />
                   </rules>
                 </nlog>";

  StringReader sr = new StringReader(xml);
  XmlReader xr = XmlReader.Create(sr);
  XmlLoggingConfiguration config = new XmlLoggingConfiguration(xr, null);
  LogManager.Configuration = config;
  //NLog is now configured just as if the XML above had been in NLog.config or app.config

  logger.Trace("Hello - Trace"); //Won't log
  logger.Debug("Hello - Debug"); //Won't log
  logger.Info("Hello - Info");   //Won't log
  logger.Warn("Hello - Warn");   //Won't log
  logger.Error("Hello - Error"); //Will log
  logger.Fatal("Hello - Fatal"); //Will log

  //Now let's change the config (the root logging level) ...
  string xml2 = @"<nlog>
                  <targets>
                     <target name='console' type='Console' layout='${message}' />
                   </targets>

                   <rules>
                     <logger name='*' minlevel='Trace' writeTo='console' />
                   </rules>
                 </nlog>";

  StringReader sr2 = new StringReader(xml2);
  XmlReader xr2 = XmlReader.Create(sr2);
  XmlLoggingConfiguration config2 = new XmlLoggingConfiguration(xr2, null);
  LogManager.Configuration = config2;

  logger.Trace("Hello - Trace"); //Will log
  logger.Debug("Hello - Debug"); //Will log
  logger.Info("Hello - Info");   //Will log
  logger.Warn("Hello - Warn");   //Will log
  logger.Error("Hello - Error"); //Will log
  logger.Fatal("Hello - Fatal"); //Will log

I'm not sure how robust this is, but this example provides a useful starting point for people that might want to try configuring like this.

You can disable the event by applying following code:

with .attr() API

$('#your_id').attr("disabled", "disabled");

or with .prop() API

$('#your_id').prop('disabled', true);

If you just need the time without the date.

  time_t rawtime;
  struct tm * timeinfo;
  time( &rawtime );
  timeinfo = localtime( &rawtime );
  printf("%02d:%02d:%02d", timeinfo->tm_hour, timeinfo->tm_min, 
    timeinfo->tm_sec);

What worked for me, I clear the opacity in .modal.backdrop.in

.modal-backdrop.in{
    filter:alpha(opacity=50);
    opacity:.5
    }

change it to

.modal-backdrop.in{
   }

You can use addresses and pointers using the Unsafe class. However as the name suggests, these methods are UNSAFE and generally a bad idea. Incorrect usage can result in your JVM randomly dying (actually the same problem get using pointers incorrectly in C/C++)

While you may be used to pointers and think you need them (because you don't know how to code any other way), you will find that you don't and you will be better off for it.

Every time you use html syntax you have to start the next razor statement with a @. So it should be @if ....

Here's the lowdown on Mac IDE's for PHP

NetBeans Free! Plus, the best functionality of all offerings. Includes inline database connections, code completion, syntax checking, color coding, split views etc. Downside: It's a memory hog on the Mac. Be prepared to allow half a gig of memory then you'll need to shut down and restart.

Komodo A step above a Text Editor. Does not support database connections or split views. Color coding and syntax checking are there to an extent. The project control on Komodo is very unwieldy and strange compared to the other IDEs.

Aptana The perfect solution. Eclipsed based and uses the Aptana PHP plug in. Real time syntax checking, word wrap, drag and drop split views, database connections and a slew of other excellent features. Downside: Not a supported product any more. Aptana Studio 2.0+ uses PDT which is a watered down, under-developed (at present) php plug in.

Zend Studio - Almost identical to Aptana, except no word wrap and you can't change alot of the php configuration on the MAC apparently due to bugs.

Coda Created by Panic, Coda has nice integration with source control and their popular FTP client, transmit. They also have a collaboration feature which is cool for pair-programming.

PhpEd with Parallels or Wine. The best IDE for Windows has all the feature you could need and is worth the effort to pass it through either Parallels or Wine.

Dreamweaver Good for Javascript/HTML/CSS, but only marginal for PHP. There is some color coding, but no syntax checking or code completion native to the package. Database connections are supported, and so are split views.

I'm using NetBeans, which is free, and feature rich. I can deal with the memory issues for a while, but it could be slow coming to the MAC.

I'm not completely certain that I understand your goal, but you can use a StringIO instance as a buffer:

>>> import StringIO 
>>> buf = StringIO.StringIO()
>>> buf.write("A = %d, B = %s\n" % (3, "bar"))
>>> buf.write("C=%d\n" % 5)
>>> print(buf.getvalue())
A = 3, B = bar
C=5

Unlike sprintf, you just pass a string to buf.write, formatting it with the % operator or the format method of strings.

You could of course define a function to get the sprintf interface you're hoping for:

def sprintf(buf, fmt, *args):
    buf.write(fmt % args)

which would be used like this:

>>> buf = StringIO.StringIO()
>>> sprintf(buf, "A = %d, B = %s\n", 3, "foo")
>>> sprintf(buf, "C = %d\n", 5)
>>> print(buf.getvalue())
A = 3, B = foo
C = 5

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

Assuming your byteData array is biger than 32 + byteSalt.length()...you're going to it's length, not byteSalt.length. You're trying to copy from beyond the array end.

When you want to read a file with a different configuration than the default one, feel free to use either mpu.aws.s3_read(s3path) directly or the copy-pasted code:

def s3_read(source, profile_name=None):
    """
    Read a file from an S3 source.

    Parameters
    ----------
    source : str
        Path starting with s3://, e.g. 's3://bucket-name/key/foo.bar'
    profile_name : str, optional
        AWS profile

    Returns
    -------
    content : bytes

    botocore.exceptions.NoCredentialsError
        Botocore is not able to find your credentials. Either specify
        profile_name or add the environment variables AWS_ACCESS_KEY_ID,
        AWS_SECRET_ACCESS_KEY and AWS_SESSION_TOKEN.
        See https://boto3.readthedocs.io/en/latest/guide/configuration.html
    """
    session = boto3.Session(profile_name=profile_name)
    s3 = session.client('s3')
    bucket_name, key = mpu.aws._s3_path_split(source)
    s3_object = s3.get_object(Bucket=bucket_name, Key=key)
    body = s3_object['Body']
    return body.read()

TLDR: A function is hard to use when it sometimes returns a promise and sometimes throws an exception. When writing an async function, prefer to signal failure by returning a rejected promise

Your particular example obfuscates some important distinctions between them:

Because you are error handling inside a promise chain, thrown exceptions get automatically converted to rejected promises. This may explain why they seem to be interchangeable - they are not.

Consider the situation below:

checkCredentials = () => {
    let idToken = localStorage.getItem('some token');
    if ( idToken ) {
      return fetch(`https://someValidateEndpoint`, {
        headers: {
          Authorization: `Bearer ${idToken}`
        }
      })
    } else {
      throw new Error('No Token Found In Local Storage')
    }
  }

This would be an anti-pattern because you would then need to support both async and sync error cases. It might look something like:

try {
  function onFulfilled() { ... do the rest of your logic }
  function onRejected() { // handle async failure - like network timeout }
  checkCredentials(x).then(onFulfilled, onRejected);
} catch (e) {
  // Error('No Token Found In Local Storage')
  // handle synchronous failure
} 

Not good and here is exactly where Promise.reject ( available in the global scope ) comes to the rescue and effectively differentiates itself from throw. The refactor now becomes:

checkCredentials = () => {
  let idToken = localStorage.getItem('some_token');
  if (!idToken) {
    return Promise.reject('No Token Found In Local Storage')
  }
  return fetch(`https://someValidateEndpoint`, {
    headers: {
      Authorization: `Bearer ${idToken}`
    }
  })
}

This now lets you use just one catch() for network failures and the synchronous error check for lack of tokens:

checkCredentials()
      .catch((error) => if ( error == 'No Token' ) {
      // do no token modal
      } else if ( error === 400 ) {
      // do not authorized modal. etc.
      }

Pick one depends on the method you are looking for!?

I will go with ParentNode.children:

As it provides namedItem method that allows me directly to get one of the children elements without looping through all children or avoiding to use getElementById etc.

e.g.

ParentNode.children.namedItem('ChildElement-ID'); // JS
ref.current.children.namedItem('ChildElement-ID'); // React
this.$refs.ref.children.namedItem('ChildElement-ID'); // Vue

I will go with Node.childNodes:

As it provides forEach method when I work with window.IntersectionObserver e.g.

nodeList.forEach((node) => { observer.observe(node) })
// IE11 does not support forEach on nodeList, but easy to be polyfilled.

On Chrome 83

Node.childNodes provides entries, forEach, item, keys, length and values

ParentNode.children provides item, length and namedItem

A jar file is a zip archive. You can extract it using 7zip (a great simple tool to open archives). You can also change its extension to zip and use whatever to unzip the file.

Now you have your class file. There is no easy way to edit class file, because class files are binaries (you won't find source code in there. maybe some strings, but not java code). To edit your class file you can use a tool like classeditor.

You have all the strings your class is using hard-coded in the class file. So if the only thing you would like to change is some strings you can do it without using classeditor.

Reassign the value of Automatically manage signing, this works for me

Are you looking for this?

ContactNumbers = new List<ContactNumber>(){ new ContactNumber("555-5555"),
                                            new ContactNumber("555-1234"),
                                            new ContactNumber("555-5678") };

Rails got ActiveSupport::CoreExtensions::String::Inflections module that provides such methods. They're all worth looking at. For your example:

'Book Author Title'.parameterize.underscore.to_sym # :book_author_title

Execute

set -o allexport

Any variables you source from a file after this will be exported in your shell.

source conf-file

When you're done execute. This will disable allexport mode.

set +o allexport

They are project files, that hold the module information and meta data.

Just add *.iml to .gitignore.

In Android Studio: Press CTRL + F9 to rebuild your project. The missing *.iml files will be generated.

If /foo/bar is on NFS (or possibly some FUSE filesystem), that might be the problem.

Either way, adding -O / --omit-dir-times to your command line will avoid it trying to set modification times on directories.
