Warning!

This is a list of random books of diverse quality. In the view of some people (with some justification), it is no longer a list of recommended books. Some of the listed books contain blatantly incorrect statements or teach wrong/harmful practices. People who are aware of such books can edit this answer to help improve it. See The C book list has gone haywire. What to do with it?, and also Deleted question audit 2018.

Reference (All Levels)

• The C Programming Language (2nd Edition) - Brian W. Kernighan and Dennis M. Ritchie (1988). Still a good, short but complete introduction to C (C90, not C99 or later versions), written by the inventor of C. However, the language has changed and good C style has developed in the last 25 years, and there are parts of the book that show its age.

• C: A Reference Manual (5th Edition) - Samuel P. Harbison and Guy R. Steele (2002). An excellent reference book on C, up to and including C99. It is not a tutorial, and probably unfit for beginners. It's great if you need to write a compiler for C, as the authors had to do when they started.

• C Pocket Reference (O'Reilly) - Peter Prinz and Ulla Kirch-Prinz (2002).

• The comp.lang.c FAQ - Steve Summit. Web site with answers to many questions about C.

• Various versions of the C language standards can be found here. There is an online version of the draft C11 standard.

• The new C standard - an annotated reference (Free PDF) - Derek M. Jones (2009). The "new standard" referred to is the old C99 standard rather than C11.

• Rationale for C99 Standard.

Beginner

• C Programming: A Modern Approach (2nd Edition) - K. N. King (2008). A good book for learning C.

• Programming in C (4th Edition) - Stephen Kochan (2014). A good general introduction and tutorial.

• C Primer Plus (5th Edition) - Stephen Prata (2004)

• A Book on C - Al Kelley/Ira Pohl (1998).

• The C Book (Free Online) - Mike Banahan, Declan Brady, and Mark Doran (1991).

• C: How to Program (8th Edition) - Paul Deitel and Harvey M. Deitel (2015). Lots of good tips and best practices for beginners. The index is very good and serves as a decent reference (just not fully comprehensive, and very shallow).

• Head First C - David Griffiths and Dawn Griffiths (2012).

• Beginning C (5th Edition) - Ivor Horton (2013). Very good explanation of pointers, using lots of small but complete programs.

• Sams Teach Yourself C in 21 Days - Bradley L. Jones and Peter Aitken (2002). Very good introductory stuff.

• C In Easy Steps (5th Edition) - Mike McGrath (2018). It is a good book for learning and referencing C.

• Effective C - Robert C Seacord (2020). A good introduction to modern C, including chapters on dynamic memory allocation, on program structure, and on debugging, testing and analysis. It has some pointers toward probable C2x features.

Intermediate

• Modern C — Jens Gustedt (2017 1st Edn; 2020 2nd Edn). Covers C in 5 levels (encounter, acquaintance, cognition, experience, ambition) from beginning C to advanced C. It covers C11 and C17, including threads and atomic access, which few other books do. Not all compilers recognize these features in all environments.

• C Interfaces and Implementations - David R. Hanson (1997). Provides information on how to define a boundary between an interface and implementation in C in a generic and reusable fashion. It also demonstrates this principle by applying it to the implementation of common mechanisms and data structures in C, such as lists, sets, exceptions, string manipulation, memory allocators, and more. Basically, Hanson took all the code he'd written as part of building Icon and lcc and pulled out the best bits in a form that other people could reuse for their own projects. It's a model of good C programming using modern design techniques (including Liskov's data abstraction), showing how to organize a big C project as a bunch of useful libraries.

• The C Puzzle Book - Alan R. Feuer (1998)

• The Standard C Library - P.J. Plauger (1992). It contains the complete source code to an implementation of the C89 standard library, along with extensive discussions about the design and why the code is designed as shown.

• 21st Century C: C Tips from the New School - Ben Klemens (2012). In addition to the C language, the book explains gdb, valgrind, autotools, and git. The comments on style are found in the last part (Chapter 6 and beyond).

• Algorithms in C - Robert Sedgewick (1997). Gives you a real grasp of implementing algorithms in C. Very lucid and clear; will probably make you want to throw away all of your other algorithms books and keep this one.

• Pointers on C - Kenneth Reek (1997).

• Problem Solving and Program Design in C (6th Edition) - Jeri R. Hanly and Elliot B. Koffman (2009).

• Data Structures - An Advanced Approach Using C - Jeffrey Esakov and Tom Weiss (1989).

• C Unleashed - Richard Heathfield, Lawrence Kirby, et al. (2000). Not ideal, but it is worth intermediate programmers practicing problems written in this book. This is a good cookbook-like approach suggested by comp.lang.c contributors.

• Object-oriented Programming with ANSI-C (Free PDF) - Axel-Tobias Schreiner (1993). The code gets a bit convoluted. If you want C++, use C++. It only uses C90, of course.

• Extreme C: Push the limits of what C and you can do - Kamran Amini (2019). This book builds on your existing C knowledge to help you become a more expert C programmer. You will gain insights into algorithm design, functions, and structures, and understand both multi-threading and multi-processing in a POSIX environment.

Expert

• Expert C Programming: Deep C Secrets - Peter van der Linden (1994). Lots of interesting information and war stories from the Sun compiler team, but a little dated in places.

• Advanced C Programming by Example - John W. Perry (1998).

• Advanced Programming in the UNIX Environment - Richard W. Stevens and Stephen A. Rago (2013). Comprehensive description of how to use the Unix APIs from C code, but not so much about the mechanics of C coding.

Uncategorized

• Essential C (Free PDF) - Nick Parlante (2003). Note that this describes the C90 language at several points (e.g., in discussing // comments and placement of variable declarations at arbitrary points in the code), so it should be treated with some caution.

• C Programming FAQs: Frequently Asked Questions - Steve Summit (1995). This is the book of the web site listed earlier. It doesn't cover C99 or the later standards.

• C in a Nutshell - Peter Prinz and Tony Crawford (2005). Excellent book if you need a reference for C99.

• Functional C - Pieter Hartel and Henk Muller (1997). Teaches modern practices that are invaluable for low-level programming, with concurrency and modularity in mind.

• The Practice of Programming - Brian W. Kernighan and Rob Pike (1999). A very good book to accompany K&R. It uses C++ and Java too.

• C Traps and Pitfalls by A. Koenig (1989). Very good, but the C style pre-dates standard C, which makes it less recommendable these days.

  ^{Some have argued for the removal of 'Traps and Pitfalls' from this list because it has trapped some people into making mistakes; others continue to argue for its inclusion. Perhaps it should be regarded as an 'expert' book because it requires a moderately extensive knowledge of C to understand what's changed since it was published.}

• MISRA-C - industry standard published and maintained by the Motor Industry Software Reliability Association. Covers C89 and C99.

  ^{Although this isn't a book as such, many programmers recommend reading and implementing as much of it as possible. MISRA-C was originally intended as guidelines for safety-critical applications in particular, but it applies to any area of application where stable, bug-free C code is desired (who doesn't want fewer bugs?). MISRA-C is becoming the de facto standard in the whole embedded industry and is getting increasingly popular even in other programming branches. There are (at least) three publications of the standard (1998, 2004, and the current version from 2012). There is also a MISRA Compliance Guidelines document from 2016, and MISRA C:2012 Amendment 1 — Additional Security Guidelines for MISRA C:2012 (published in April 2016).}

  ^{Note that some of the strictures in the MISRA rules are not appropriate to every context. For example, directive 4.12 states "Dynamic memory allocation shall not be used". This is appropriate in the embedded systems for which the MISRA rules are designed; it is not appropriate everywhere. (Compilers, for instance, generally use dynamic memory allocation for things like symbol tables, and to do without dynamic memory allocation would be difficult, if not preposterous.)}

• Archived lists of ACCU-reviewed books on Beginner's C (116 titles) from 2007 and Advanced C (76 titles) from 2008. Most of these don't look to be on the main site anymore, and you can't browse that by subject anyway.

Warnings

There is a list of books and tutorials to be cautious about at the ISO 9899 Wiki, which is not itself formally associated with ISO or the C standard, but contains information about the C standard (though it hails the release of ISO 9899:2011 and does not mention the release of ISO 9899:2018).

Be wary of books written by Herbert Schildt. In particular, you should stay away from C: The Complete Reference (4th Edition, 2000), known in some circles as C: The Complete Nonsense.

Also do not use the book Let Us C (16^th Edition, 2017) by Yashwant Kanetkar. Many people view it as an outdated book that teaches Turbo C and has lots of obsolete, misleading and incorrect material. For example, page 137 discusses the expected output from printf("%d %d %d\n", a, ++a, a++) and does not categorize it as undefined behaviour as it should. It also consistently promotes unportable and buggy coding practices, such as using gets, %[\n]s in scanf, storing return value of getchar in a variable of type char or using fflush on stdin.

Learn C The Hard Way (2015) by Zed Shaw. A book with mixed reviews. A critique of this book by Tim Hentenaar:

To summarize my views, which are laid out below, the author presents the material in a greatly oversimplified and misleading way, the whole corpus is a bundled mess, and some of the opinions and analyses he offers are just plain wrong. I've tried to view this book through the eyes of a novice, but unfortunately I am biased by years of experience writing code in C. It's obvious to me that either the author has a flawed understanding of C, or he's deliberately oversimplifying to the point where he's actually misleading the reader (intentionally or otherwise).

"Learn C The Hard Way" is not a book that I could recommend to someone who is both learning to program and learning C. If you're already a competent programmer in some other related language, then it represents an interesting and unusual exposition on C, though I have reservations about parts of the book. _{Jonathan Leffler}

Outdated

• Practical C Programming (3rd Edition) - Steve Oualline (1997)(Beginner)

There are three types of allocation — static, automatic, and dynamic.

Static Allocation means, that the memory for your variables is allocated when the program starts. The size is fixed when the program is created. It applies to global variables, file scope variables, and variables qualified with static defined inside functions.

Automatic memory allocation occurs for (non-static) variables defined inside functions, and is usually stored on the stack (though the C standard doesn't mandate that a stack is used). You do not have to reserve extra memory using them, but on the other hand, have also limited control over the lifetime of this memory. E.g: automatic variables in a function are only there until the function finishes.

void func() {
    int i; /* `i` only exists during `func` */
}

Dynamic memory allocation is a bit different. You now control the exact size and the lifetime of these memory locations. If you don't free it, you'll run into memory leaks, which may cause your application to crash, since at some point of time, system cannot allocate more memory.

int* func() {
    int* mem = malloc(1024);
    return mem;
}

int* mem = func(); /* still accessible */

In the upper example, the allocated memory is still valid and accessible, even though the function terminated. When you are done with the memory, you have to free it:

free(mem);

You should really be using checkboxes if there will be an instance where something isn't selected.

according to the W3C

If no radio button in a set sharing the same control name is initially "on", user agent behavior for choosing which control is initially "on" is undefined. Note. Since existing implementations handle this case differently, the current specification differs from RFC 1866 ([RFC1866] section 8.1.2.4), which states:

At all times, exactly one of the radio buttons in a set is checked. If none of the elements of a set of radio buttons specifies `CHECKED', then the user agent must check the first radio button of the set initially.

Since user agent behavior differs, authors should ensure that in each set of radio buttons that one is initially "on".

If you don't want to chunk your data together with the data callback you can always use the readable callback like this:

// Read Body when Available
request.on("readable", function(){
  request.body = '';
  while (null !== (request.body += request.read())){}
});

// Do something with it
request.on("end", function(){
  request.body //-> POST Parameters as String
});

This approach modifies the incoming request, but as soon as you finish your response the request will be garbage collected, so that should not be a problem.

An advanced approach would be to check the body size first, if you're afraid of huge bodies.

An example with for loop (I prefer List Comprehensions).

a, b = '[br]', '<br />'
for i, v in enumerate(words):
    if a in v:
        words[i] = v.replace(a, b)
print(words)
# ['how', 'much', 'is<br/>', 'the', 'fish<br/>', 'no', 'really']

Using the scroll-behavior CSS property:

(which is supported in modern browsers but not Edge):

a {
  display: inline-block;
  padding: 5px 7%;
  text-decoration: none;
}

nav, section {
  display: block;
  margin: 0 auto;
  text-align: center;
}

nav {
  width: 350px;
  padding: 5px;
}

section {

  height: 130px;
  overflow-y: scroll;
  border: 1px solid black;
  font-size: 0; 
  scroll-behavior: smooth;    /* <----- THE SECRET ---- */
}

section div{
  display: flex;
  align-items: center;
  justify-content: center;

To contribute my 5 cents to the thorough explanation from Amadan.

Where classes are a description "of a type" in an abstract way. Objects are their realizations: the living breathing thing. In the object-orientated world there are principal ideas you can almost call the essence of everything. They are:

1. encapsulation (won't elaborate on this)
2. inheritance
3. polymorphism

Objects have one, or more characteristics (= Attributes) and behaviors (= Methods). The behavior mostly depends on the characteristics. Classes define what the behavior should accomplish in a general way, but as long as the class is not realized (instantiated) as an object it remains an abstract concept of a possibility. Let me illustrate with the help of "inheritance" and "polymorphism".

    class Human:
        gender
        nationality
        favorite_drink
        core_characteristic
        favorite_beverage
        name
        age

        def love    
        def drink
        def laugh
        def do_your_special_thing                

    class Americans(Humans)
        def drink(beverage):
            if beverage != favorite_drink: print "You call that a drink?"
            else: print "Great!" 

    class French(Humans)
        def drink(beverage, cheese):
            if beverage == favourite_drink and cheese == None: print "No cheese?" 
            elif beverage != favourite_drink and cheese == None: print "Révolution!"

    class Brazilian(Humans)
        def do_your_special_thing
            win_every_football_world_cup()

    class Germans(Humans)
        def drink(beverage):
            if favorite_drink != beverage: print "I need more beer"
            else: print "Lecker!" 

    class HighSchoolStudent(Americans):
        def __init__(self, name, age):
             self.name = name
             self.age = age

jeff = HighSchoolStudent(name, age):
hans = Germans()
ronaldo = Brazilian()
amelie = French()

for friends in [jeff, hans, ronaldo]:
    friends.laugh()
    friends.drink("cola")
    friends.do_your_special_thing()

print amelie.love(jeff)
>>> True
print ronaldo.love(hans)
>>> False

Some characteristics define human beings. But every nationality differs somewhat. So "national-types" are kinda Humans with extras. "Americans" are a type of "Humans " and inherit some abstract characteristics and behavior from the human type (base-class) : that's inheritance. So all Humans can laugh and drink, therefore all child-classes can also! Inheritance (2).

But because they are all of the same kind (Type/base-class : Humans) you can exchange them sometimes: see the for-loop at the end. But they will expose an individual characteristic, and thats Polymorphism (3).

So each human has a favorite_drink, but every nationality tend towards a special kind of drink. If you subclass a nationality from the type of Humans you can overwrite the inherited behavior as I have demonstrated above with the drink() Method. But that's still at the class-level and because of this it's still a generalization.

hans = German(favorite_drink = "Cola")

instantiates the class German and I "changed" a default characteristic at the beginning. (But if you call hans.drink('Milk') he would still print "I need more beer" - an obvious bug ... or maybe that's what i would call a feature if i would be a Employee of a bigger Company. ;-)! )

The characteristic of a type e.g. Germans (hans) are usually defined through the constructor (in python : __init__) at the moment of the instantiation. This is the point where you define a class to become an object. You could say breath life into an abstract concept (class) by filling it with individual characteristics and becoming an object.

But because every object is an instance of a class they share all some basic characteristic-types and some behavior. This is a major advantage of the object-orientated concept.

To protect the characteristics of each object you encapsulate them - means you try to couple behavior and characteristic and make it hard to manipulate it from outside the object. That's Encapsulation (1)

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

CORS is Cross Origin Resource Sharing, you get this error if you are trying to access from one domain to another domain.

Try using JSONP. In your case, JSONP should work fine because it only uses the GET method.

Try something like this:

var url = "https://api.getevents.co/event?&lat=41.904196&lng=12.465974";
$http({
    method: 'JSONP',
    url: url
}).
success(function(status) {
    //your code when success
}).
error(function(status) {
    //your code when fails
});

response.session doesn't work anymore because response.authResponse is the new way to access the response content after the oauth migration.

You can try: a=[0,1,2,3,4,5,6,7,8,9];

Just make sure put single space before and after "and" Keyword..

I found a couple of ways to do this with web based APIs. I think the US Postal Service would be the most accurate, since Zip codes are their thing, but Ziptastic looks much easier.

Using the US Postal Service HTTP/XML API

According to this page on the US Postal Service website which documents their XML based web API, specifically Section 4.0 (page 22) of this PDF document, they have a URL where you can send an XML request containing a 5 digit Zip Code and they will respond with an XML document containing the corresponding City and State.

According to their documentation, here's what you would send:

http://SERVERNAME/ShippingAPITest.dll?API=CityStateLookup&XML=<CityStateLookupRequest%20USERID="xxxxxxx"><ZipCode ID= "0"><Zip5>90210</Zip5></ZipCode></CityStateLookupRequest>

And here's what you would receive back:

<?xml version="1.0"?> 
<CityStateLookupResponse> 
    <ZipCode ID="0"> 
        <Zip5>90210</Zip5> 
        <City>BEVERLY HILLS</City> 
        <State>CA</State> 
    </ZipCode> 
</CityStateLookupResponse>

USPS does require that you register with them before you can use the API, but, as far as I could tell, there is no charge for access. By the way, their API has some other features: you can do Address Standardization and Zip Code Lookup, as well as the whole suite of tracking, shipping, labels, etc.

Using the Ziptastic HTTP/JSON API (no longer supported)

Update: As of August 13, 2017, Ziptastic is now a paid API and can be found here

This is a pretty new service, but according to their documentation, it looks like all you need to do is send a GET request to http://ziptasticapi.com, like so:

GET http://ziptasticapi.com/48867

And they will return a JSON object along the lines of:

{"country": "US", "state": "MI", "city": "OWOSSO"}

Indeed, it works. You can test this from a command line by doing something like:

curl http://ziptasticapi.com/48867 

$.ajax(
{
    type: 'post',
    url: 'mail.php',
    data: form.serialize(),
    beforeSend: function()
    {
        $('.content').html('loading...');
    },
    success: function(data)
    {
        $('.content').html(data);
    },
    error: function()
    {
        $('.content').html('error');
    }
});

have fun playing arround!

if you should have quick loading times which prevent te loading showing, you can add a timeout of some sort.

If I had to guess, you did this:

import datetime

at the top of your code. This means that you have to do this:

datetime.datetime.strptime(date, "%Y-%m-%d")

to access the strptime method. Or, you could change the import statement to this:

from datetime import datetime

and access it as you are.

The people who made the datetime module also named their class datetime:

#module  class    method
datetime.datetime.strptime(date, "%Y-%m-%d")

419 error happens when you don`t post csrf_token. in your post method you must add this token along other variables.

My experience in Visual Studio 2010 is that there are two changes needed so as to not need DLL's. From the project property page (right click on the project name in the Solution Explorer window):

1. Under Configuration Properties --> General, change the "Use of MFC" field to "Use MFC in a Static Library".

2. Under Configuration Properties --> C/C++ --> Code Generation, change the "Runtime Library" field to "Multi-Threaded (/MT)"

Not sure why both were needed. I used this to remove a dependency on glut32.dll.

Added later: When making these changes to the configurations, you should make them to "All Configurations" --- you can select this at the top of the Properties window. If you make the change to just the Debug configuration, it won't apply to the Release configuration, and vice-versa.

To add to K3N's cardinal splines method and perhaps address T. J. Crowder's concerns about curves 'dipping' in misleading places, I inserted the following code in the getCurvePoints() function, just before res.push(x);

if ((y < _pts[i+1] && y < _pts[i+3]) || (y > _pts[i+1] && y > _pts[i+3])) {
    y = (_pts[i+1] + _pts[i+3]) / 2;
}
if ((x < _pts[i] && x < _pts[i+2]) || (x > _pts[i] && x > _pts[i+2])) {
    x = (_pts[i] + _pts[i+2]) / 2;
}

This effectively creates a (invisible) bounding box between each pair of successive points and ensures the curve stays within this bounding box - ie. if a point on the curve is above/below/left/right of both points, it alters its position to be within the box. Here the midpoint is used, but this could be improved upon, perhaps using linear interpolation.

The simple way is using System.Diagnostics.Debug.WriteLine()

Your can then read what you're writing to the output by clicking the menu "DEBUG" -> "Windows" -> "Output".

This was just happening to me, but none of the suggestions above worked. I changed directories ("cd ~/tmp") and suddenly the command

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

worked for me. Prior to changing directories I had been in a directory that is a Git repository. Perhaps that was interfering with the ruby and Git commands in the Brew install script.

You can get multi-threading using Napa.js.

https://github.com/Microsoft/napajs

"Napa.js is a multi-threaded JavaScript runtime built on V8, which was originally designed to develop highly iterative services with non-compromised performance in Bing. As it evolves, we find it useful to complement Node.js in CPU-bound tasks, with the capability of executing JavaScript in multiple V8 isolates and communicating between them. Napa.js is exposed as a Node.js module, while it can also be embedded in a host process without Node.js dependency."

But be alert. User can upload any type of file and also can hack your server or system by uploading a malicious or php file. In this script there should be some validations. Thank you.

Configuration

You can enable GZIP compression entirely in your Web.config file. This is particularly useful if you're on shared hosting and can't configure IIS directly, or you want your config to carry between all environments you target.

<system.webServer>
  <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
    <dynamicTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </dynamicTypes>
    <staticTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </staticTypes>
  </httpCompression>
  <urlCompression doStaticCompression="true" doDynamicCompression="true"/>
</system.webServer>

Testing

To test whether compression is working or not, use the developer tools in Chrome or Firebug for Firefox and ensure the HTTP response header is set:

Content-Encoding: gzip

Note that this header won't be present if the response code is 304 (Not Modified). If that's the case, do a full refresh (hold shift or control while you press the refresh button) and check again.

AFAK there is no model.summary() like equivalent in pytorch

Meanwhile you can refer script by szagoruyko, which gives a nice visualizaton like in resnet18-example

Try this:

 declare @MyFloatVal float;

    set @MyFloatVal=(select convert(decimal(10, 2), 10.254000))

    select  @MyFloatVal

    Convert(decimal(18,2),r.AdditionAmount) as AdditionAmount

You are getting that error because when the param1 if statements are evaluated, param is always null due to being scoped variables without delayed expansion.

When parentheses are used, all the commands and variables within those parentheses are expanded. And at that time, param1 has no value making the if statements invalid. When using delayed expansion, the variables are only expanded when the command is actually called.

Also I recommend using if not defined command to determine if a variable is set.

If checking for truth:

if foo

For false:

if not foo

For none:

if foo is None

For non-none:

if foo is not None

For getattr() the correct behaviour is not to return None, but raise an AttributError error instead - unless your class is something like defaultdict.

The easiest way to match both

^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$

and

^[0-9]{3}-[0-9]{3}-[0-9]{4}$

is to use alternation ((...|...)): specify them as two mostly-separate options:

^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$

By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234, not (123)123-1234. So you might want to write:

^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$

(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)

There are two ways to use this variable:

• passing it as a command line argument just like Job mentioned:

  cmake -DCMAKE_INSTALL_PREFIX=< install_path > ..

• assigning value to it in CMakeLists.txt:

  SET(CMAKE_INSTALL_PREFIX < install_path >)

  But do remember to place it BEFORE PROJECT(< project_name>) command, otherwise it will not work!

The code you're using is also going to include a fadeout effect. Is this what you want to achieve? If not, it might make more sense to just add the following INSIDE "Small.php".

<meta http-equiv="refresh" content="15" >

This adds a refresh every 15seconds to the small.php page which should mean if called by PHP into another page, only that "frame" will reload.

Let us know if it worked/solved your problem!?

-Brad

Which model is the "best fitting model" depends on what you mean by "best". R has tools to help, but you need to provide the definition for "best" to choose between them. Consider the following example data and code:

x <- 1:10
y <- x + c(-0.5,0.5)

plot(x,y, xlim=c(0,11), ylim=c(-1,12))

fit1 <- lm( y~offset(x) -1 )
fit2 <- lm( y~x )
fit3 <- lm( y~poly(x,3) )
fit4 <- lm( y~poly(x,9) )
library(splines)
fit5 <- lm( y~ns(x, 3) )
fit6 <- lm( y~ns(x, 9) )

fit7 <- lm( y ~ x + cos(x*pi) )

xx <- seq(0,11, length.out=250)
lines(xx, predict(fit1, data.frame(x=xx)), col='blue')
lines(xx, predict(fit2, data.frame(x=xx)), col='green')
lines(xx, predict(fit3, data.frame(x=xx)), col='red')
lines(xx, predict(fit4, data.frame(x=xx)), col='purple')
lines(xx, predict(fit5, data.frame(x=xx)), col='orange')
lines(xx, predict(fit6, data.frame(x=xx)), col='grey')
lines(xx, predict(fit7, data.frame(x=xx)), col='black')

Which of those models is the best? arguments could be made for any of them (but I for one would not want to use the purple one for interpolation).

There are a few ways to run a batch file on start up. The one I usually use is through task scheduler. If you press the windows key then type task scheduler it will come up as an option (or find through administerative tools).

When you create a new task you can chose from trigger options such as 'At log on' for a specific user, on workstation unlock etc. Then in actions you select start a program and put the full path to your batch script (there is also an option to put any command line args required).

Here is a an example script to launch Stack Overflow in Firefox:

@echo off

title Auto launch Stack Overflow


start firefox http://stackoverflow.com/questions/tagged/python+or+sql+or+sqlite+or+plsql+or+oracle+or+windows-7+or+cmd+or+excel+or+access+or+vba+or+excel-vba+or+access-vba?sort=newest

REM Optional - I tend to log these sorts of events so that you can see what has happened afterwards
echo %date% %time%, %computername% >> %logs%\StackOverflowAuto.csv

exit

For the <tr>'s just set

tr {
   line-height: 25px;
   min-height: 25px;
   height: 25px;
}

It works with bootstrap also. For the 100% height, 100% must be 100% of something. Therefore, you must define a fixed height for one of the containers, or the body. I guess you want the entire page to be 100%, so (example) :

body {
    height: 700px;
}
.table100, .row, .container, .table-responsive, .table-bordered  {
    height: 100%;
}

A workaround not to set a static height is by forcing the height in code according to the viewport :

$('body').height(document.documentElement.clientHeight);

all the above in this fiddle -> http://jsfiddle.net/LZuJt/

Note : I do not care that you have 25% height on #description, and 100% height on table. Guess it is just an example. And notice that clientHeight is not right since the documentElement is an iframe, but you'll get the picture in your own projekt :)

It indicates that you are using a decorator. Here is Bruce Eckel's example from 2008.

First you need to create a mock m_contractsDao and set it up. Assuming that the class is ContractsDao:

ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(any(String.class))).thenReturn("Some result");

Then inject the mock into m_orderSvc and call your method.

m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work(); 

Finally, verify that the mock was called properly:

verify(mock_contractsDao, times(1)).save("Parameter I'm expecting");

Without using CDATA, try

<xsl:value-of select="'&#xA;'" />

Note the double and single quotes.

That is particularly useful if you are not creating xml aka text. <xsl:output method="text" />

From a SQLServerCentral.Com article by Ken Powers:

The Semicolon

The semicolon character is a statement terminator. It is a part of the ANSI SQL-92 standard, but was never used within Transact-SQL. Indeed, it was possible to code T-SQL for years without ever encountering a semicolon.

Usage

There are two situations in which you must use the semicolon. The first situation is where you use a Common Table Expression (CTE), and the CTE is not the first statement in the batch. The second is where you issue a Service Broker statement and the Service Broker statement is not the first statement in the batch.

Remember that if you use ng-click for routing you will not be able to right-click the element and choose 'open in new tab' or ctrl clicking the link. I try to use ng-href when in comes to navigation. ng-click is better to use on buttons for operations or visual effects like collapse. But About I would not recommend. If you change the route you might need to change in a lot of placed in the application. Have a method returning the link. ex: About. This method you place in a utility

I've had the same problem.

Use CSS to hide is not the best solution, because sometimes you want users without JS can see the div.. The cleanest solution is to hide the div with JQuery. But the div is visible about 0.5 seconde, which is problematic if the div is on the top of the page.

In these cases, I use an intermediate solution, without JQuery. This one works and is immediate :

<script>document.write('<style>.js_hidden { display: none; }</style>');</script>

<div class="js_hidden">This div will be hidden for JS users, and visible for non JS users.</div>

Of course, you can still add all the effects you want on the div, JQuery toggle() for example. And you will get the best behaviour possible (imho) :

• for non JS users, the div is visible directly
• for JS users, the div is hidden and has toggle effect.

I recently wrote a post about how I've been doing it at Udacity for the last couple years. This method has meant we've been able to update Bootstrap whenever we wanted to without having merge conflicts, thrown out work, etc. etc.

The post goes more in depth with examples, but the basic idea is:

• Keep a pristine copy of bootstrap and overwrite it externally.
• Modify one file (bootstrap's variables.less) to include your own variables.
• Make your site file @include bootstrap.less and then your overrides.

This does mean using LESS, and compiling it down to CSS before shipping it to the client (client-side LESS if finicky, and I generally avoid it) but it is EXTREMELY good for maintainability/upgradability, and getting LESS compilation is really really easy. The linked github code has an example using grunt, but there are many ways to achieve this -- even GUIs if that's your thing.

Using this solution, your example problem would look like:

• Change the nav bar color with @navbar-inverse-bg in your variables.less (not bootstrap's)
• Add your own nav bar styles to your bootstrap_overrides.less, overwriting anything you need to as you go.
• Happiness.

When it comes time to upgrade your bootstrap, you just swap out the pristine bootstrap copy and everything will still work (if bootstrap makes breaking changes, you'll need to update your overrides, but you'd have to do that anyway)

Blog post with walk-through is here.

Code example on github is here.

In SVG (contrasted with HTML), you will want to use <image> instead of <img> for elements.

Try changing your last block with:

var imgs = svg.selectAll("image").data([0]);
            imgs.enter()
            .append("svg:image")
            ...

It's also good to note that an each loop cannot be broken out of — to break, use _.find instead.

This has been here quite a while but posting this. Might be useful for someone.

@RequestMapping( "/{id}/**" )
public void foo( @PathVariable String id, HttpServletRequest request ) {
    String urlTail = new AntPathMatcher()
            .extractPathWithinPattern( "/{id}/**", request.getRequestURI() );
}

Its due to PHP that has a file size restriction for uploads.

If you have terminal/shell access then the above answers @Kyotoweb will work.

one way to get it done is that you create an .htaccess/ini file file to change PHP settings to get the sql file uploaded through PHPmyAdmin.

php_value upload_max_filesize 120M //file size
php_value post_max_size 120M
php_value max_execution_time 200
php_value max_input_time 200

Note you should remove this file after upload.

If you only want to add Datapoints above the bars, you could easily do it with:

 for i in range(len(frequencies)): # your number of bars
    plt.text(x = x_values[i]-0.25, #takes your x values as horizontal positioning argument 
    y = y_values[i]+1, #takes your y values as vertical positioning argument 
    s = data_labels[i], # the labels you want to add to the data
    size = 9) # font size of datalabels

There is the Jquery alert plugin

$.alerts.okButton = ' Yes ';
$.alerts.cancelButton = ' No ';

Make sure your element with the .date-picker class does NOT already have a hasDatepicker class. If it does, even an attempt to re-initialize with $myDatepicker.datepicker(); will fail! Instead you need to do...

$myDatepicker.removeClass('hasDatepicker').datepicker();

You could use a literal eval:

>>> ast.literal_eval('0xdeadbeef')
3735928559

Or just specify the base as argument to int:

>>> int('deadbeef', 16)
3735928559

A trick that is not well known, if you specify the base 0 to int, then Python will attempt to determine the base from the string prefix:

>>> int("0xff", 0)
255
>>> int("0o644", 0)
420
>>> int("0b100", 0)
4
>>> int("100", 0)
100

In a new sheet (where you want to create a new pivot table) press the key combination (Alt+D+P). In the list of data source options choose "Microsoft Excel list of database". Click Next and select the pivot table that you want to use as a source (select starting with the actual headers of the fields). I assume that this range is rather static and if you refresh the source pivot and it changes it's size you would have to re-size the range as well. Hope this helps.

Here my common used script below. I use this for running scripts on two tables/views with SQL job and send results as two HTML tables via mail. Ofcourse you should create mail profile before run this.

Index Lengths & MySQL / MariaDB

Laravel uses the utf8mb4 character set by default, which includes support for storing "emojis" in the database. If you are running a version of MySQL older than the 5.7.7 release or MariaDB older than the 10.2.2 release, you may need to manually configure the default string length generated by migrations in order for MySQL to create indexes for them. You may configure this by calling the Schema::defaultStringLength method within your AppServiceProvider:

use Illuminate\Support\Facades\Schema;

/**
 * Bootstrap any application services.
 *
 * @return void
 */
public function boot()
{
    Schema::defaultStringLength(191);
}

Alternatively, you may enable the innodb_large_prefix option for your database. Refer to your database's documentation for instructions on how to properly enable this option.

This is because require() does not exist in the browser/client-side JavaScript.

Now you're going to have to make some choices about your client-side JavaScript script management.

You have three options:

1. Use the <script> tag.
2. Use a CommonJS implementation. It has synchronous dependencies like Node.js
3. Use an asynchronous module definition (AMD) implementation.

CommonJS client side-implementations include (most of them require a build step before you deploy):

1. Browserify - You can use most Node.js modules in the browser. This is my personal favorite.
2. Webpack - Does everything (bundles JavaScript code, CSS, etc.). It was made popular by the surge of React, but it is notorious for its difficult learning curve.
3. Rollup - a new contender. It leverages ES6 modules and includes tree-shaking abilities (removes unused code).

You can read more about my comparison of Browserify vs (deprecated) Component.

AMD implementations include:

1. RequireJS - Very popular amongst client-side JavaScript developers. It is not my taste because of its asynchronous nature.

Note, in your search for choosing which one to go with, you'll read about Bower. Bower is only for package dependencies and is unopinionated on module definitions like CommonJS and AMD.

You should implement the Comparator interface.

example:

public class CustomComparator implements Comparator<CustomObject> 
{
    @Override
    public int compare(CustomObject o1, CustomObject o2) {
        return o1.getId().compareTo(o2.getId());
    }
}

Then you can use the Collections classes Collections.sort() method:

Collections.sort(list, new CustomComparator());

If you remove directives attribute it should work.

@Component({
    selector: 'parent',
    template: `
            <h1>Parent Component</h1>
            <child></child>
        `
    })
    export class ParentComponent{}


@Component({
    selector: 'child',    
    template: `
            <h4>Child Component</h4>
        `
    })
    export class ChildComponent{}

Directives are like components but they are used in attributes. They also have a declarator @Directive. You can read more about directives Structural Directives and Attribute Directives.

There are two other kinds of Angular directives, described extensively elsewhere: (1) components and (2) attribute directives.

A component manages a region of HTML in the manner of a native HTML element. Technically it's a directive with a template.

Also if you are open the glossary you can find that components are also directives.

Directives fall into one of the following categories:

• Components combine application logic with an HTML template to render application views. Components are usually represented as HTML elements. They are the building blocks of an Angular application.

• Attribute directives can listen to and modify the behavior of other HTML elements, attributes, properties, and components. They are usually represented as HTML attributes, hence the name.

• Structural directives are responsible for shaping or reshaping HTML layout, typically by adding, removing, or manipulating elements and their children.

The difference that components have a template. See Angular Architecture overview.

A directive is a class with a @Directive decorator. A component is a directive-with-a-template; a @Component decorator is actually a @Directive decorator extended with template-oriented features.

The @Component metadata doesn't have directives attribute. See Component decorator.

In case this is useful to anyone I had this same issue. I was bringing in a footer into a web page via jQuery. Inside that footer were some Google scripts for ads and retargeting. I had to move those scripts from the footer and place them directly in the page and that eliminated the notice.

In the interest of coverage. I put forward an implementation using lambda expressions.

C++11

#include <vector>
#include <algorithm>

using namespace std;

vector< MyStruct > values;

sort( values.begin( ), values.end( ), [ ]( const MyStruct& lhs, const MyStruct& rhs )
{
   return lhs.key < rhs.key;
});

C++14

#include <vector>
#include <algorithm>

using namespace std;

vector< MyStruct > values;

sort( values.begin( ), values.end( ), [ ]( const auto& lhs, const auto& rhs )
{
   return lhs.key < rhs.key;
});

As others said, Stopwatch should be the right tool for this. There can be few improvements made to it though, see this thread specifically: Benchmarking small code samples in C#, can this implementation be improved?.

I have seen some useful tips by Thomas Maierhofer here

Basically his code looks like:

//prevent the JIT Compiler from optimizing Fkt calls away
long seed = Environment.TickCount;

//use the second Core/Processor for the test
Process.GetCurrentProcess().ProcessorAffinity = new IntPtr(2);

//prevent "Normal" Processes from interrupting Threads
Process.GetCurrentProcess().PriorityClass = ProcessPriorityClass.High;

//prevent "Normal" Threads from interrupting this thread
Thread.CurrentThread.Priority = ThreadPriority.Highest;

//warm up
method();

var stopwatch = new Stopwatch()
for (int i = 0; i < repetitions; i++)
{
    stopwatch.Reset();
    stopwatch.Start();
    for (int j = 0; j < iterations; j++)
        method();
    stopwatch.Stop();
    print stopwatch.Elapsed.TotalMilliseconds;
}

Another approach is to rely on Process.TotalProcessTime to measure how long the CPU has been kept busy running the very code/process, as shown here This can reflect more real scenario since no other process affects the measurement. It does something like:

 var start = Process.GetCurrentProcess().TotalProcessorTime;
 method();
 var stop = Process.GetCurrentProcess().TotalProcessorTime;
 print (end - begin).TotalMilliseconds;

A naked, detailed implementation of the samething can be found here.

I wrote a helper class to perform both in an easy to use manner:

    interface IStopwatch
    {
        bool IsRunning { get; }

    }

        {
            get { return stopwatch.Elapsed; }
        }

        public bool IsRunning
        {
            get { return stopwatch.IsRunning; }
        }



        public TimeWatch()
        {
            if (!Stopwatch.IsHighResolution)
                throw new NotSupportedException("Your hardware doesn't support high resolution counter");

            //prevent the JIT Compiler from optimizing Fkt calls away
            long seed = Environment.TickCount;

            //use the second Core/Processor for the test
            Process.GetCurrentProcess().ProcessorAffinity = new IntPtr(2);

            //prevent "Normal" Processes from interrupting Threads
            Process.GetCurrentProcess().PriorityClass = ProcessPriorityClass.High;

            //prevent "Normal" Threads from interrupting this thread
            Thread.CurrentThread.Priority = ThreadPriority.Highest;
        }



        public void Start()
        {
            stopwatch.Start();
        }

        {
            stopwatch.Stop();
        }

            stopwatch.Reset();
        }
    }

                if (IsRunning)
                    throw new NotImplementedException("Getting elapsed span while watch is running is not implemented");

                return endTime - startTime;
            }
        }

        public bool IsRunning
        {
            get { return isRunning; }
        }



        public void Start()
        {
            startTime = Process.GetCurrentProcess().TotalProcessorTime;
            isRunning = true;
        }

        for (int i = 0; i < timings.Length; i++)
        {
            stopwatch.Reset();
            stopwatch.Start();
            for (int j = 0; j < iterations; j++)
                action();
            stopwatch.Stop();
            timings[i] = stopwatch.Elapsed.TotalMilliseconds;
            print timings[i];
        }
        print "normalized mean: " + timings.NormalizedMean().ToString();
    }

    public static void BenchmarkCpu(Action action, int iterations = 10000)
    {
        Benchmark<CpuWatch>(action, iterations);
    }
}

Just call

Clock.BenchmarkTime(() =>
{
    //code

}, 10000000);

or

Clock.BenchmarkCpu(() =>
{
    //code

}, 10000000);

The last part of the Clock is the tricky part. If you want to display the final timing, its up to you to choose what sort of timing you want. I wrote an extension method NormalizedMean which gives you the mean of the read timings discarding the noise. I mean I calculate the the deviation of each timing from the actual mean, and then I discard the values which was farer (only the slower ones) from the mean of deviation (called absolute deviation; note that its not the often heard standard deviation), and finally return the mean of remaining values. This means, for instance, if timed values are { 1, 2, 3, 2, 100 } (in ms or whatever), it discards 100, and returns the mean of { 1, 2, 3, 2 } which is 2. Or if timings are { 240, 220, 200, 220, 220, 270 }, it discards 270, and returns the mean of { 240, 220, 200, 220, 220 } which is 220.

public static double NormalizedMean(this ICollection<double> values)
{
    if (values.Count == 0)
        return double.NaN;

    var deviations = values.Deviations().ToArray();
    var meanDeviation = deviations.Sum(t => Math.Abs(t.Item2)) / values.Count;
    return deviations.Where(t => t.Item2 > 0 || Math.Abs(t.Item2) <= meanDeviation).Average(t => t.Item1);
}

public static IEnumerable<Tuple<double, double>> Deviations(this ICollection<double> values)
{
    if (values.Count == 0)
        yield break;

    var avg = values.Average();
    foreach (var d in values)
        yield return Tuple.Create(d, avg - d);
}

The memory associated with arr is freed automatically when arr goes out of scope. It is either a local variable, or allocated statically, but it is not dynamically allocated.

A simple rule for you to follow is that you must only every call free() on a pointer that was returned by a call to malloc, calloc or realloc.

You can also declare it HTML safe from the code:

from flask import Markup
value = Markup('<strong>The HTML String</strong>')

Then pass that value to the templates and they don't have to |safe it.

System.IO.DirectoryInfo myDirInfo = new DirectoryInfo(myDirPath);

foreach (FileInfo file in myDirInfo.GetFiles())
{
    file.Delete(); 
}
foreach (DirectoryInfo dir in myDirInfo.GetDirectories())
{
    dir.Delete(true); 
}

If you like namespace constant, you can leverage struct, Friday Q&A 2011-08-19: Namespaced Constants and Functions

// in the header
extern const struct MANotifyingArrayNotificationsStruct
{
    NSString *didAddObject;
    NSString *didChangeObject;

const struct MANotifyingArrayNotificationsStruct MANotifyingArrayNotifications = {
    .didAddObject = @"didAddObject",
    .didChangeObject = @"didChangeObject",
    .didRemoveObject = @"didRemoveObject"
};

MongoDB shell version v4.2.6
Node v14.2.0

Assuming you have a Tour Model: tourModel.js

const mongoose = require('mongoose');

const tourSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'A tour must have a name'],
    unique: true,
    trim: true,
  },
  createdAt: {
    type: Date,
    default: Date.now(),
  },
});
const Tour = mongoose.model('Tour', tourSchema);

module.exports = Tour;

Now you want to delete all tours at once from your MongoDB, I also providing connection code to connect with the remote cluster. I used deleteMany(), if you do not pass any args to deleteMany(), then it will delete all the documents in Tour collection.

const mongoose = require('mongoose');
const Tour = require('./../../models/tourModel');
const conStr = 'mongodb+srv://lord:<PASSWORD>@cluster0-eeev8.mongodb.net/tour-guide?retryWrites=true&w=majority';
const DB = conStr.replace('<PASSWORD>','ADUSsaZEKESKZX');
mongoose.connect(DB, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useFindAndModify: false,
    useUnifiedTopology: true,
  })
  .then((con) => {
    console.log(`DB connection successful ${con.path}`);
  });

const deleteAllData = async () => {
  try {
    await Tour.deleteMany();
    console.log('All Data successfully deleted');
  } catch (err) {
    console.log(err);
  }
};

In terminal try this:

ls -lA /usr/local/bin | grep pip

in my case i get:

-rwxr-xr-x 1 root  root      284 ??? 13 16:20 pip
-rwxr-xr-x 1 root  root      204 ??? 27 16:37 pip2
-rwxr-xr-x 1 root  root      204 ??? 27 16:37 pip2.7
-rwxr-xr-x 1 root  root      292 ??? 13 16:20 pip-3.4

So pip2 || pip2.7 in my case works, and pip

MD5 encrypting is possible, but decrypting is still unknown (to me). However, there are many ways to compare these things.

1. Using compare methods like so:

   <?php
     $db_pass = $P$BX5675uhhghfhgfhfhfgftut/0;
     $my_pass = "mypass";
     if ($db_pass === md5($my_pass)) {
       // password is matched
     } else {
       // password didn't match
     }
   

2. Only for WordPress users. If you have access to your PHPMyAdmin, focus you have because you paste that hashing here: $P$BX5675uhhghfhgfhfhfgftut/0, WordPress user_pass is not only MD5 format it also uses utf8_mb4_cli charset so what to do?

   That's why I use another Approach if I forget my WordPress password I use

   I install other WordPress with new password :P, and I then go to PHPMyAdmin and copy that hashing from the database and paste that hashing to my current PHPMyAdmin password ( which I forget )

   EASY is use this :

   1. password = "ARJUNsingh@123"
   2. password_hasing = " $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1 "
   3. Replace your $P$BX5675uhhghfhgfhfhfgftut/0 with my $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1

I USE THIS APPROACH FOR MY SELF WHEN I DESIGN THEMES AND PLUGINS

WORDPRESS USE THIS

Here's some info if someone comes upon this in 2019.

I think reduce vs map + filter might be somewhat dependent on what you need to loop through. Not sure on this but reduce does seem to be slower.

One thing is for sure - if you're looking for performance improvements the way you write the code is extremely important!

Here a JS perf test that shows the massive improvements when typing out the code fully rather than checking for "falsey" values (e.g. if (string) {...}) or returning "falsey" values where a boolean is expected.

Hope this helps someone

I have the same issue, when I close the chrome window popup browser inspector its working fine for me.

Get rid of the semicolon after WordGame.

You really should have discovered this problem when the class was a lot smaller. When you're writing code, you should be compiling about every time you add half a dozen lines.

Please follow these Steps:

For Eclipse:

• Go to your Project's Properties
  
• Navigate to the Java Build Path
• Then go to the Libraries tab. There click the Add External JARs Button on the Right pane.
  
• Select the android-support-v4.jar file, usually the path for the Jar file is :
  YOUR_DRIVE\android-sdks\extras\android\support\v4\android-support-v4.jar
  
• After adding android-support-v4.jar Library, navigate to the Order and Export tab and put check mark on the android-support-v4 Library file.
  
• After doing the above, Clean the Project and Build it.
  
• Problem Solved.

For Android Studio:

Short Version:

• Add the following line to your build.gradle file:
  implementation 'com.android.support:support-v4:YOUR_TARGET_VERSION'

Long Version:

• Go to File -> Project Structure

• Go to "Dependencies" Tab -> Click on the Plus sign -> Go to "Library dependency"

• Select the support library "support-v4 (com.android.support:support-v4:YOUR_TARGET_VERSION)"

• Navigate to your "build.gradle" inside your App Directory and double check if your desired Android Support Library has been added to your dependencies.

• Rebuild your project and now everything should work.

take a look at shutil. shutil.copyfile(src, dst) will copy a file to another file.

Note that shutil.copyfile will not create directories that do not already exist. for that, use os.makedirs

As stated, unit tests are designed to run without interaction.

However, you can debug unit tests, just like any other code. The easiest way is to use the Debug button in the Test Results tab.

Being able to debug means being able to use breakpoints. Being able to use breakpoints, then, means being able to use Tracepoints, which I find extremely useful in every day debugging.

Essentially, Tracepoints allow you to write to the Output window (or, more accurately, to standard output). Optionally, you can continue to run, or you can stop like a regular breakpoint. This gives you the "functionality" you are asking for, without the need to rebuild your code, or fill it up with debug information.

Simply add a breakpoint, and then right-click on that breakpoint. Select the "When Hit..." option:

Which brings up the dialog:

A few things to note:

1. Notice that the breakpoint is now shown as a diamond, instead of a sphere, indicating a trace point
2. You can output the value of a variable by enclosing it like {this}.
3. Uncheck the "Continue Execution" checkbox to have the code break on this line, like any regular breakpoint
4. You have the option of running a macro. Please be careful - you may cause harmful side effects.

See the documentation for more details.

$articles =DB::table('articles')
                ->join('categories','articles.id', '=', 'categories.id')
                ->join('user', 'articles.user_id', '=', 'user.id')
                ->select('articles.id','articles.title','articles.body','user.user_name', 'categories.category_name')
                ->get();
return view('myarticlesview',['articles'=>$articles]);

you can add this code to web.config in asp mvc

   <system.webServer>
    <staticContent>
      <remove fileExtension=".srt" />
      <mimeMap fileExtension=".srt" mimeType="text/srt" />
      <remove fileExtension=".vtt" />
      <mimeMap fileExtension=".vtt" mimeType="text/vtt" />
    </staticContent>
  </system.webServer>

you can change file extension with your file extension

There's at least 7 different ways to test if a number is odd or even. But, if you read through these benchmarks, you'll find that as TGH mentioned above, the modulus operation is the fastest:

if (x % 2 == 0)
               //even number
        else
               //odd number

Here are a few other methods (from the website) :

//bitwise operation
if ((x & 1) == 0)
       //even number
else
      //odd number

//bit shifting
if (((x >> 1) << 1) == x)
       //even number
else
       //odd number

//using native library
System.Math.DivRem((long)x, (long)2, out outvalue);
if ( outvalue == 0)
       //even number
else
       //odd number

Using inline styles:

<input type="text" style="text-align: right"/>

or, put it in a style sheet, like so:

<style>
   .rightJustified {
        text-align: right;
    }
</style>

and reference the class:

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

If you don't mind using 3rd party libraries, my cyclops-react lib has extensions for all JDK Collection types, including Map. You can directly use the map or bimap methods to transform your Map. A MapX can be constructed from an existing Map eg.

  MapX<String, Column> y = MapX.fromMap(orgColumnMap)
                               .map(c->new Column(c.getValue());

If you also wish to change the key you can write

  MapX<String, Column> y = MapX.fromMap(orgColumnMap)
                               .bimap(this::newKey,c->new Column(c.getValue());

bimap can be used to transform the keys and values at the same time.

As MapX extends Map the generated map can also be defined as

  Map<String, Column> y

You can specify a Python version for pip to use:

pip3.4 install requests

Python 3.4 has pip support built-in, so you can also use:

python3.4 -m pip install

If you're running Ubuntu (or probably Debian as well), you'll need to install the system pip3 separately:

sudo apt-get install python3-pip

This will install the pip3 executable, so you can use it, as well as the earlier mentioned python3.4 -m pip:

pip3 install requests

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.

data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}


def my_function(**data):
    schoolname  = data['school']
    cityname = data['city']
    standard = data['class']
    studentname = data['name']

You can call the function like this:

my_function(**data)

Also, make sure that your device isn't on airplane mode and/or that data usage is enabled.

Try this:

$r = Page()->getInstanceByName($page);

It worked for me in a similar case.

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

If you wish, you can also use the column names instead of column numbers.

For example, if you want to read data from DataGridView on the 4. row and the "Name" column. It provides me a better understanding for which variable I am dealing with.

dataGridView.Rows[4].Cells["Name"].Value.ToString();

Hope it helps.

It's important to write full class path in the xml. I got 'Error inflating class' when only subclass's name was written in.

Breakpoints are just used to check the execution of your code, wherever you will put breakpoints the execution will stop there, so you can just check that your project execution is going forward or not. To get more details follow link:-

If you need old XLS format. Below code for ansii 'cp1251'.

import xlrd

file=u'C:/Landau/task/6200.xlsx'

try:
    book = xlrd.open_workbook(file,encoding_override="cp1251")  
except:
    book = xlrd.open_workbook(file)
print("The number of worksheets is {0}".format(book.nsheets))
print("Worksheet name(s): {0}".format(book.sheet_names()))
sh = book.sheet_by_index(0)
print("{0} {1} {2}".format(sh.name, sh.nrows, sh.ncols))
print("Cell D30 is {0}".format(sh.cell_value(rowx=29, colx=3)))
for rx in range(sh.nrows):
   print(sh.row(rx))

You are looking for str.rsplit(), with a limit:

print x.rsplit('-', 1)[0]

.rsplit() searches for the splitting string from the end of input string, and the second argument limits how many times it'll split to just once.

Another option is to use str.rpartition(), which will only ever split just once:

print x.rpartition('-')[0]

For splitting just once, str.rpartition() is the faster method as well; if you need to split more than once you can only use str.rsplit().

Demo:

>>> x = 'http://test.com/lalala-134'
>>> print x.rsplit('-', 1)[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rsplit('-', 1)[0]
'something-with-a-lot-of'

and the same with str.rpartition()

>>> print x.rpartition('-')[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rpartition('-')[0]
'something-with-a-lot-of'

Forge's SHA-256 implementation is fast and reliable.

To run tests on several SHA-256 JavaScript implementations, go to http://brillout.github.io/test-javascript-hash-implementations/.

The results on my machine suggests forge to be the fastest implementation and also considerably faster than the Stanford Javascript Crypto Library (sjcl) mentioned in the accepted answer.

Forge is 256 KB big, but extracting the SHA-256 related code reduces the size to 4.5 KB, see https://github.com/brillout/forge-sha256

Maybe I read the problem wrong, but I believe you already have inserted the course 11 records and simply need to update those that meet the criteria you listed with course 6's data.

If this is the case, you'll want to use an UPDATE...FROM statement:

UPDATE MyTable
SET
    complete = 1,
    complete_date = newdata.complete_date,
    post_score = newdata.post_score
FROM
    (
    SELECT
        userID,
        complete_date,
        post_score
    FROM MyTable
    WHERE
        courseID = 6
        AND complete = 1
        AND complete_date > '8/1/2008'
    ) newdata
WHERE
    CourseID = 11
    AND userID = newdata.userID

I've just had the same issue - for me Privacy Badger on Firefox was the issue - not adblocker. Posting for posterity

I'm installing on a Raspberry Pi 3, with Raspbian 8. The curl method failed for me (got a line 1: Not: command not found error upon asking for docker-compose --version) and the solution of @sunapi386 seemed a little out-dated, so I tried this which worked:

First clean things up from previous efforts:

sudo rm /usr/local/bin/docker-compose
sudo pip uninstall docker-compose

Then follow this guidance re docker-compose on Rpi:

sudo apt-get -y install python-pip
sudo pip install docker-compose

For me (on 1 Nov 2017) this results in the following response to docker-compose --version:

docker-compose version 1.16.1, build 6d1ac219

In my case this happened after installing sql server and the solution was as described in this answer

Since you are open to jQuery, this plugin seems to do the trick.

Check if your object is a list or a vector. To do this, type is.list(yourobject). If this is true, try renaming it x<-unlist(yourobject). This will make it into a vector you can plot.

If you are already using Newtonsoft.Json and don't want to install Microsoft.AspNet.WebApi.Client:

 var myInstance = JsonConvert.DeserializeObject<MyClass>(

A HashSet has an internal structure (hash), where items can be searched and identified quickly. The downside is that iterating through a HashSet (or getting an item by index) is rather slow.

So why would someone want be able to know if an entry already exists in a set?

One situation where a HashSet is useful is in getting distinct values from a list where duplicates may exist. Once an item is added to the HashSet it is quick to determine if the item exists (Contains operator).

Other advantages of the HashSet are the Set operations: IntersectWith, IsSubsetOf, IsSupersetOf, Overlaps, SymmetricExceptWith, UnionWith.

If you are familiar with the object constraint language then you will identify these set operations. You will also see that it is one step closer to an implementation of executable UML.

After you put all configuration on .env file, if you already run php artisan serve, RESTART IT.

An alternative way:

SELECT ...
FROM bla
WHERE finalDate = (SELECT MAX(finalDate) FROM bla) AND
      rownum = 1

Before answering your question:

If you do not have a Person class, first you must consider whether you want to create a Person class. Do you plan to reuse the concept of a Person very often? If so, you should create a Person class. (You have access to this data in the form of a passed-in variable and you don't care about being messy and sloppy.)

To answer your question:

You have access to their birthyear, so in that case you likely have a Person class with a someperson.birthdate field. In that case, you have to ask yourself, is someperson.age a value that is reusable?

The answer is yes. We often care about age more than the birthdate, so if the birthdate is a field, age should definitely be a derived field. (A case where we would not do this: if we were calculating values like someperson.chanceIsFemale or someperson.positionToDisplayInGrid or other irrelevant values, we would not extend the Person class; you just ask yourself, "Would another program care about the fields I am thinking of extending the class with?" The answer to that question will determine if you extend the original class, or make a function (or your own class like PersonAnalysisData or something).)

Short Answer

Yes.

Explanation

It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.

The following example will show you the use of multiple classes.

The first class makes the text color red.

The second class makes the background-color blue.

See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.

Result: multiple CSS statements in different classes will stack up.

You can read more about CSS Specificity.

CSS

.class1 {
    color:red;
}

.class2 {
    background-color:blue;
}

HTML

<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>

Live demo

function traverse(o) {
    for (var i in o) {
        if (!!o[i] && typeof(o[i])=="object") {
            console.log(i, o[i]);
            traverse(o[i]);
        } else {
            console.log(i, o[i]);
        }
    }
}

+ means a space only in application/x-www-form-urlencoded content, such as the query part of a URL:

http://www.example.com/path/foo+bar/path?query+name=query+value

In this URL, the parameter name is query name with a space and the value is query value with a space, but the folder name in the path is literally foo+bar, not foo bar.

%20 is a valid way to encode a space in either of these contexts. So if you need to URL-encode a string for inclusion in part of a URL, it is always safe to replace spaces with %20 and pluses with %2B. This is what eg. encodeURIComponent() does in JavaScript. Unfortunately it's not what urlencode does in PHP (rawurlencode is safer).

See Also HTML 4.01 Specification application/x-www-form-urlencoded

Example:

DECLARE @Str NVARCHAR(MAX) = N'
            foo   bar
        Foo           Bar        

'

PRINT '[' + @Str + ']'

DECLARE @StrPrv NVARCHAR(MAX) = N''

WHILE ((@StrPrv <> @Str) AND (@Str IS NOT NULL)) BEGIN
    SET @StrPrv = @Str

    -- Beginning
    IF EXISTS (SELECT 1 WHERE @Str LIKE '[' + CHAR(13) + CHAR(10) + CHAR(9) + ']%')
        SET @Str = LTRIM(RIGHT(@Str, LEN(@Str) - 1))

    -- Ending
    IF EXISTS (SELECT 1 WHERE @Str LIKE '%[' + CHAR(13) + CHAR(10) + CHAR(9) + ']')
        SET @Str = RTRIM(LEFT(@Str, LEN(@Str) - 1))
END

PRINT '[' + @Str + ']'

Result

[
            foo   bar
        Foo           Bar        

]
[foo   bar
        Foo           Bar]

Using fnTrim

SELECT dbo.fnTrim(colName)

I will hijack this thread to point out that this error may also happen when target of Popen is not executable. Learnt it hard way when by accident I have had override a perfectly executable binary file with zip file.

For those that comfortable with Python, https://github.com/Russell91/pythonpy is a nice choice to solve this problem.

$ echo "a:b:c:d:e" | py -x 'x.split(":")[-1]'

From the pythonpy help: -x treat each row of stdin as x.

With that tool, it is easy to write python code that gets applied to the input.

Edit (Dec 2020): Pythonpy is no longer online. Here is an alternative:

$ echo "a:b:c:d:e" | python -c 'import sys; sys.stdout.write(sys.stdin.read().split(":")[-1])'

it contains more boilerplate code (i.e. sys.stdout.read/write) but requires only std libraries from python.

Raw strings are not a different kind of string. They are a different way of describing a string in your source code. Once the string is created, it is what it is.

"\\s+" should do the trick

Social.class.getSimpleName()

getSimpleName() : Returns the simple name of the underlying class as given in the source code. Returns an empty string if the underlying class is anonymous. The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".

Use ...from table(... :

create or replace type numbertype
as object
(nr number(20,10) )
/ 

create or replace type number_table
as table of numbertype
/ 

create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
  open p_ref_result for
    select *
    from employees , (select /*+ cardinality(tab 10) */ tab.nr from table(p_numbers) tab) tbnrs 
    where id = tbnrs.nr; 
end; 
/ 

This is one of the rare cases where you need a hint, else Oracle will not use the index on column id. One of the advantages of this approach is that Oracle doesn't need to hard parse the query again and again. Using a temporary table is most of the times slower.

edit 1 simplified the procedure (thanks to jimmyorr) + example

create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
  open p_ref_result for
    select /*+ cardinality(tab 10) */ emp.*
    from  employees emp
    ,     table(p_numbers) tab
    where tab.nr = id;
end;
/

Example:

set serveroutput on 

create table employees ( id number(10),name varchar2(100));
insert into employees values (3,'Raymond');
insert into employees values (4,'Hans');
commit;

declare
  l_number number_table := number_table();
  l_sys_refcursor sys_refcursor;
  l_employee employees%rowtype;
begin
  l_number.extend;
  l_number(1) := numbertype(3);
  l_number.extend;
  l_number(2) := numbertype(4);
  tableselect(l_number, l_sys_refcursor);
  loop
    fetch l_sys_refcursor into l_employee;
    exit when l_sys_refcursor%notfound;
    dbms_output.put_line(l_employee.name);
  end loop;
  close l_sys_refcursor;
end;
/

This will output:

Raymond
Hans

If anyone doesn't understand how Array.sort() works with integers, read this answer.

Alphabetical order:

By default, the sort() method sorts the values as strings in alphabetical and ascending order.

const myArray = [104, 140000, 99];
myArray.sort();
console.log(myArray); // output is [104, 140000, 99]

Ascending order with array.sort(compareFunction):

const myArray = [104, 140000, 99];
myArray.sort(function(a, b){
  return a - b;
});
console.log(myArray); // output is [99, 104, 140000]

Explanation from w3schools:

compareFunction defines an alternative sort order. The function should return a negative, zero, or positive value, depending on the arguments, like: function(a, b){return a-b} When the sort() method compares two values, it sends the values to the compare function, and sorts the values according to the returned (negative, zero, positive) value.

Example:

When comparing 40 and 100, the sort() method calls the compare function(40,100).

The function calculates 40-100, and returns -60 (a negative value).

The sort function will sort 40 as a value lower than 100.

Descending order with array.sort(compareFunction):

const myArray = [104, 140000, 99];
myArray.sort(function(a, b){
  return b - a;
});
console.log(myArray); // output is [140000, 104, 99]

This time we calculated with b - a(i.e., 100-40) which returns a positive value.

In some cases one wants to both save and print a base r plot. I spent a bit of time and came up with this utility function:

x = 1:10

basesave = function(expr, filename, print=T) {
  #extension
  exten = stringr::str_match(filename, "\\.(\\w+)$")[, 2]

  switch(exten,
         png = {
           png(filename)
           eval(expr, envir = parent.frame())
           dev.off()
         },
         {stop("filetype not recognized")})


  #print?
  if (print) eval(expr, envir = parent.frame())

  invisible(NULL)
}

#plots, but doesn't save
plot(x)

#saves, but doesn't plot
png("test.png")
plot(x)
dev.off()

#both
basesave(quote(plot(x)), "test.png")

#works with pipe too
quote(plot(x)) %>% basesave("test.png")

Note that one must use quote, otherwise the plot(x) call is run in the global environment and NULL gets passed to basesave().

<span style='color:blue '> your message/text </span>

So here it is a perfect html css style entry inside a notebook ipynb file.

Of course you can choose your favourite color here and then your text.

This is a very common issue.

One solution is to kill adb server and restart it through command prompt. Sometimes this may not help out.

Just go to Window Task Manager to kill adb process and restart Eclipse.

Will work perfect :)

In my case this was required:
npm install @angular/compiler --save
npm install @angular/cli --save-dev

I solved the problem switching the workspace.

1. Go to File (Switch workspace)
2. Select the destination and create a folder named Workspace
3. Run a Hello World and close Eclipse (notice that Eclipse creates the folder RemoteSystemsTempFiles automatically)
4. now copy all your projects into the new folder Workspace
5. Open Eclipse and if necessary (sometimes Eclipse does not show the projects) import all of them (go to File/ Open projects from File System)

You can use a table

<table class="formcontrols" >   
    <tr>
        <td>
            <label for="firstName">FirstName:</label>
        </td>
        <td  style="padding-left:10px;">
            <input id="firstName" name="firstName" value="John">
        </td>
    </tr>
    <tr>
        <td>
            <label for="Test">Last name:</label>
        </td>
        <td  style="padding-left:10px;">
            <input id="lastName" name="lastName" value="Travolta">
        </td>
    </tr>
</table>

The result would be: ImageResult

I would like you to have a look at redux http://redux.js.org/index.html

They have very well defined way of handling async calls ie API calls, and instead of using jQuery for API calls, I would like to recommend using fetch or request npm packages, fetch is currently supported by modern browsers, but a shim is also available for server side.

There is also this another amazing package superagent, which has alot many options when making an API request and its very easy to use.

This worked for me.

self._name = name + '.mp4'
self._cap = VideoCapture(0)
self._fourcc = VideoWriter_fourcc(*'MP4V')
self._out = VideoWriter(self._name, self._fourcc, 20.0, (640,480))

Check: http://www.php.net/require and http://www.php.net/include

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

You can turn on your PHP errors with error_reporting:

error_reporting(E_ALL);
ini_set('display_errors', 'on');

Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:

Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.

You should set display_errors = 1 in your php.ini file and restart the server.

If you are okay with just having IE open the JSON into a notepad, you can change your system's default program for .json files to Notepad.

To do this, create or find a .json file, right mouse click, and select "Open With" or "Choose Default Program."

This might come in handy if you by chance want to use Internet Explorer but your IT company wont let you edit your registry. Otherwise, I recommend the above answers.

For SQL Server, if using a newer version, you can use

select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='tableName'

There are different ways to get the schema. Using ADO.NET, you can use the schema methods. Use the DbConnection's GetSchema method or the DataReader'sGetSchemaTable method.

Provided that you have a reader for the for the query, you can do something like this:

using(DbCommand cmd = ...)
using(var reader = cmd.ExecuteReader())
{
    var schema = reader.GetSchemaTable();
    foreach(DataRow row in schema.Rows)
    {
        Debug.WriteLine(row["ColumnName"] + " - " + row["DataTypeName"])
    }
}

Once you have the source trees, e.g.

diff -ENwbur repos1/ repos2/ 

Even better

diff -ENwbur repos1/ repos2/  | kompare -o -

and have a crack at it in a good gui tool :)

• -Ewb ignore the bulk of whitespace changes
• -N detect new files
• -u unified
• -r recurse

Based on the answer from #squiguy, to get a true timestamp I would type cast it from float.

>>> import time
>>> ts = int(time.time())
>>> print(ts)
1389177318

At least that's the concept.

TimeSpan span = end-start;
double totalMinutes = span.TotalMinutes;

It's explained well here.

If the input variables are combined linearly, as in an MLP [multilayer perceptron], then it is rarely strictly necessary to standardize the inputs, at least in theory. The reason is that any rescaling of an input vector can be effectively undone by changing the corresponding weights and biases, leaving you with the exact same outputs as you had before. However, there are a variety of practical reasons why standardizing the inputs can make training faster and reduce the chances of getting stuck in local optima. Also, weight decay and Bayesian estimation can be done more conveniently with standardized inputs.

You could probably try this to get file sizes in kB and MB Until the file size in bytes would be upto 7 digits, the outcome would be in kbs. 7 seems to be the magic number here. After which, if the bytes would have 7 to 10 digits, we would have to divide it by 10**3(n) where n is the appending action . This pattern would repeat for every 3 digits added.

let fileSize = myInp.files[0].size.toString();

if(fileSize.length < 7) return `${Math.round(+fileSize/1024).toFixed(2)}kb`
    return `${(Math.round(+fileSize/1024)/1000).toFixed(2)}MB`

it goes like this: 1D:

 type[] name=new type[size]  //or =new type[]{.....elements...}

2D:

 type[][]name=new type[size][] //second brackets are emtpy

then as you use this array :

 name[i]=new type[size_of_sec.Dim]

or You can declare something like a matrix

type[ , ] name=new type [size1,size2]

Instead of

onClick="parent.location='http://www.facebook.com/'"

try using

Many answers have explained how to call a method from the parent which has been overridden in the child.

However

"how do you call a parent class's method from child class?"

could also just mean:

"how do you call inherited methods?"

You can call methods inherited from a parent class just as if they were methods of the child class, as long as they haven't been overwritten.

e.g. in python 3:

class A():
  def bar(self, string):
    print("Hi, I'm bar, inherited from A"+string)

class B(A):
  def baz(self):
    self.bar(" - called by baz in B")

B().baz() # prints out "Hi, I'm bar, inherited from A - called by baz in B"

yes, this may be fairly obvious, but I feel that without pointing this out people may leave this thread with the impression you have to jump through ridiculous hoops just to access inherited methods in python. Especially as this question rates highly in searches for "how to access a parent class's method in Python", and the OP is written from the perspective of someone new to python.

I found: https://docs.python.org/3/tutorial/classes.html#inheritance to be useful in understanding how you access inherited methods.

Despite following the accepted answer exactly, I was still unable to get the service to start-- I was instead given a failure message during installation stating that the service that was just installed could not be started, as it did not exist, despite using this.serviceInstaller.ServiceName rather than a literal...

I eventually found an alternative solution that makes use of the command line:

private void serviceInstaller_AfterInstall(object sender, InstallEventArgs e) {
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.FileName = "cmd.exe";
        startInfo.Arguments = "/C sc start " + this.serviceInstaller.ServiceName;

        Process process = new Process();
        process.StartInfo = startInfo;
        process.Start();
    }

I solved my issue with : Java Build Path -> JRE system library - > Edit -> Alternate JRE -> -> Finish

As it was configured to JDK folder so it was giving Exception

git checkout -b branch/name

git pull origin branch/name

You can run your file in http-server.

1> Have Node.js installed in your system.

2> In CMD, run the command npm install http-server -g

3> Navigate to the specific path of your file folder in CMD and run the command http-server

4> Go to your browser and type localhost:8080. Your Application should run there.

Thanks:)

There is a much simpler solution for that.
Actually treating the items of JArray as JObject works.
Here is an example:
Let's say we have such array of JSON objects:

JArray jArray = JArray.Parse(@"[
              {
                ""name"": ""Croke Park II"",
                ""url"": ""http://twitter.com/search?q=%22Croke+Park+II%22"",
                ""promoted_content"": null,
                ""query"": ""%22Croke+Park+II%22"",
                ""events"": null
              },
              {
                ""name"": ""Siptu"",
                ""url"": ""http://twitter.com/search?q=Siptu"",
                ""promoted_content"": null,
                ""query"": ""Siptu"",
                ""events"": null
              }]");

To get access each item we just do the following:

foreach (JObject item in jArray)
{
    string name = item.GetValue("name").ToString();
    string url = item.GetValue("url").ToString();
    // ...
}

There is an easy way, just remove the symbolic link from "/usr/bin". It will work.

Gotcha!

You have to use RegisterStartupScript instead of RegisterClientScriptBlock

Here My Example.

If, like me, you don't have access to the puppet master and need to print debug logs to inspect variables on your puppet client machine, you can try writing to a file from your puppet code itself:

file { '/tmp/puppet_debug.log':
  content => inline_template('<%= @variable_x.to_s %>'),
}

Shortly:

$("#selectBox").attr("selectedIndex",index)

where index is the selected index as integer.

import time 

startTime = time.time()
# Your code here !
print ('The script took {0} second !'.format(time.time() - startTime))

The previous code works for me with no problem !

Another poster already pointed out that your hashcode implementation will result in a lot of collisions due to the way that you're adding values together. I'm willing to be that, if you look at the HashMap object in a debugger, you'll find that you have maybe 200 distinct hash values, with extremely long bucket chains.

If you always have values in the range 0..51, each of those values will take 6 bits to represent. If you always have 5 values, you can create a 30-bit hashcode with left-shifts and additions:

    int code = a[0];
    code = (code << 6) + a[1];
    code = (code << 6) + b[0];
    code = (code << 6) + b[1];
    code = (code << 6) + b[2];
    return code;

The left-shift is fast, but will leave you with hashcodes that aren't evenly distributed (because 6 bits implies a range 0..63). An alternative is to multiply the hash by 51 and add each value. This still won't be perfectly distributed (eg, {2,0} and {1,52} will collide), and will be slower than the shift.

    int code = a[0];
    code *= 51 + a[1];
    code *= 51 + b[0];
    code *= 51 + b[1];
    code *= 51 + b[2];
    return code;

I had this error aswell.

I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

I had the same problem here, solved like this:

Just add another application-{yourprofile}.yml where "yourprofile" could be "client".

In my case I just wanted to remove Redis in a Dev profile, so I added a application-dev.yml next to the main application.yml and it did the job.

In this file I put:

spring.autoconfigure.exclude: org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration,org.springframework.boot.autoconfigure.data.redis.RedisRepositoriesAutoConfiguration

this should work with properties files as well.

I like the fact that there is no need to change the application code to do that.

var listItems= "";
var jsonData = jsonObj.d;
    for (var i = 0; i < jsonData.Table.length; i++){
      listItems+= "<option value='" + jsonData.Table[i].stateid + "'>" + jsonData.Table[i].statename + "</option>";
    }
    $("#<%=DLState.ClientID%>").html(listItems);

Example

   <html>
    <head></head>
    <body>
      <select id="DLState">
      </select>
    </body>
    </html>

    /*javascript*/
    var jsonList = {"Table" : [{"stateid" : "2","statename" : "Tamilnadu"},
                {"stateid" : "3","statename" : "Karnataka"},
                {"stateid" : "4","statename" : "Andaman and Nicobar"},
                 {"stateid" : "5","statename" : "Andhra Pradesh"},
                 {"stateid" : "6","statename" : "Arunachal Pradesh"}]}

    $(document).ready(function(){
      var listItems= "";
      for (var i = 0; i < jsonList.Table.length; i++){
        listItems+= "<option value='" + jsonList.Table[i].stateid + "'>" + jsonList.Table[i].statename + "</option>";
      }
      $("#DLState").html(listItems);
    });    

Even after adding @Autowire if your class is not a RestController or Configuration Class, the applicationContext object was coming as null. Tried Creating new class with below and it is working fine:

@Component
public class SpringContext implements ApplicationContextAware{

   private static ApplicationContext applicationContext;

   @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws 
     BeansException {
    this.applicationContext=applicationContext;
   }
 }

you can then implement a getter method in the same class as per your need like getting the Implemented class reference by:

    applicationContext.getBean(String serviceName,Interface.Class)

Use Below Code instead of your code

<EditText 
    android:id="@+id/searchbox"  
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:maxLines="1"
    android:inputType="text"
    android:scrollHorizontally="true"
    android:ellipsize="end"
    android:layout_weight="1"
    android:layout_marginTop="2dp"
    android:drawablePadding="10dp"
    android:background="@drawable/edittext"
    android:drawableLeft="@drawable/folder_full"
    android:drawableRight="@drawable/search"
    android:paddingLeft="15dp"
    android:hint="search..."/>

A constructor should no have a return type . remove void before each constructor .

Some very basic characteristic of a constructor :

a. Same name as class b. no return type. c. will be called every time an object is made with the class. for eg- in your program if u made two objects of Flow, Flow flow1=new Flow(); Flow flow2=new Flow(); then Flow constructor will be called for 2 times.

d. If you want to call the constructor just for once then declare that as static (static constructor) and dont forget to remove any access modifier from static constructor ..

Just to add some specific settings, I had a similar setup (with Apache 2.0.63 reverse proxying onto Tomcat 5.0.27).

For certain URLs the Tomcat server could take perhaps 20 minutes to return a page.

I ended up modifying the following settings in the Apache configuration file to prevent it from timing out with its proxy operation (with a large over-spill factor in case Tomcat took longer to return a page):

Timeout 5400
ProxyTimeout 5400

Some backgound

ProxyTimeout alone wasn't enough. Looking at the documentation for Timeout I'm guessing (I'm not sure) that this is because while Apache is waiting for a response from Tomcat, there is no traffic flowing between Apache and the Browser (or whatever http client) - and so Apache closes down the connection to the browser.

I found that if I left the Timeout setting at its default (300 seconds), then if the proxied request to Tomcat took longer than 300 seconds to get a response the browser would display a "502 Proxy Error" page. I believe this message is generated by Apache, in the knowledge that it's acting as a reverse proxy, before it closes down the connection to the browser (this is my current understanding - it may be flawed).

The proxy error page says:

Proxy Error

The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET.

Reason: Error reading from remote server

...which suggests that it's the ProxyTimeout setting that's too short, while investigation shows that Apache's Timeout setting (timeout between Apache and the client) that also influences this.

You can use two different techniques to achieve this.

The first one is with javascript: set the scrollTop property of the scrollable element (e.g. document.body.scrollTop = 1000;).

The second is setting the link to point to a specific id in the page e.g.

<a href="mypage.html#sectionOne">section one</a>

Then if in your target page you'll have that ID the page will be scrolled automatically.

You're removing and then incrementing, which means you'll be one ahead of yourself. Instead, remove in reverse so you never mess up your next item.

for (int i = ChunkList.Count-1; i >=0; i--)
{
    if (ChunkList[i].UniqueID == ChunkID)
    {
        ChunkList.RemoveAt(i);
    }
}

You can also try this

Private Declare Function GetWindowText Lib "user32.dll" (ByVal hwnd As IntPtr, ByVal lpString As StringBuilder, ByVal cch As Integer) As Integer

I always use Declare Function instead of DllImport... Its more simply, its shorter and does the same

I guess anther way, possibly faster, to achieve this is 1) Use dict comprehension to get desired dict (i.e., taking 2nd col of each array) 2) Then use pd.DataFrame to create an instance directly from the dict without loop over each col and concat.

Assuming your mat looks like this (you can ignore this since your mat is loaded from file):

In [135]: mat = {'a': np.random.randint(5, size=(4,2)),
   .....: 'b': np.random.randint(5, size=(4,2))}

In [136]: mat
Out[136]: 
{'a': array([[2, 0],
        [3, 4],
        [0, 1],
        [4, 2]]), 'b': array([[1, 0],
        [1, 1],
        [1, 0],
        [2, 1]])}

Then you can do:

In [137]: df = pd.DataFrame ({name:mat[name][:,1] for name in mat})

In [138]: df
Out[138]: 
   a  b
0  0  0
1  4  1
2  1  0
3  2  1

[4 rows x 2 columns]

MySQL makes a difference between "localhost" and "127.0.0.1".

It might be possible that 'root'@'localhost' is not allowed because there is an entry in the user table that will only allow root login from 127.0.0.1.

This could also explain why some application on your server can connect to the database and some not because there are different ways of connecting to the database. And you currently do not allow it through "localhost".

Simply type start in the command prompt:

start

This will open up new cmd windows.

No, unless you want to break compatibility and your compiler supports it.

Just use parenthesis and 'count'. This applies to Powershell v3

(get-alias).count

this.TextBox3.Text = DateTime.Now.ToString("MM.dd.yyyy");

thisReader.GetString(int columnIndex)

If you want to use a library rather than doing it yourself:

The most commonly used way is using jQuery for this purpose:

var safestring = $('<div>').text(unsafestring).html();

If you want to to encode all the HTML entities you will have to use a library or write it yourself.

You can use a more compact library than jQuery, like HTML Encoder and Decode

Couple of ways using count or sum

In [338]: df
Out[338]:
  col1 education
0    a       9th
1    b       9th
2    c       8th

In [335]: df.loc[df.education == '9th', 'education'].count()
Out[335]: 2

In [336]: (df.education == '9th').sum()
Out[336]: 2

In [337]: df.query('education == "9th"').education.count()
Out[337]: 2

You can simply do the following :

$fi = new FilesystemIterator(__DIR__, FilesystemIterator::SKIP_DOTS);
printf("There were %d Files", iterator_count($fi));

For setting the Socket timeout, you need to follow these steps:

import socket
socks = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socks.settimeout(10.0) # settimeout is the attr of socks.

Using the approach mentioned in the answer by Rick Byers:

top -p `pgrep java | paste -sd "," -`

but I had more than 20 processes running so following command can be helpful for someone who encounter a similar situation.

top -p `pgrep java | head -n 20 | paste -sd "," -`

pgrep gets the list of processes with given name - java in this case. head is used to get first 20 pids because top cannot handle more than 20 pids when using -p argument. Finally paste joins the list of pids with ','.

You can control the process name you are looking for in the above command and the number of processes with that name you are interested to watch. You can ignore the head -n 20 part if the number of your processes with the given name is less than 20.

import org.apache.commons.lang3.StringUtils;

// path = "http://cdn.gs.com/new/downloads/Q22010MVR_PressRelease.pdf.null"
StringUtils.removeEnd(path, ".null");
// path = "http://cdn.gs.com/new/downloads/Q22010MVR_PressRelease.pdf"

You can use inline styling to limit the height:

<img src="" class="img-responsive" alt="" style="max-height: 400px;">

I was getting the same error while trying to restore SQL 2008 R2 backup db in SQL 2012 DB. I guess the error is due to insufficient permissions to place .mdf and .ldf files in C drive. I tried one simple thing then I succeeded in restoring it successfully.

Try this:

In the Restore DB wizard windows, go to Files tab, change the restore destination from C: to some other drive. Then proceed with the regular restore process. It will definitely get restores successfully!

Hope this helps you too. Cheers :)

If the request could not be correctly parsed (including the request entity/body) the appropriate response is 400 Bad Request [1].

RFC 4918 states that 422 Unprocessable Entity is applicable when the request entity is syntactically well-formed, but semantically erroneous. So if the request entity is garbled (like a bad email format) use 400; but if it just doesn't make sense (like @example.com) use 422.

If the issue is that, as stated in the question, user name/email already exists, you could use 409 Conflict [2] with a description of the conflict, and a hint about how to fix it (in this case, "pick a different user name/email"). However in the spec as written, 403 Forbidden [3] can also be used in this case, arguments about HTTP Authorization notwithstanding.

412 Precondition Failed [4] is used when a precondition request header (e.g. If-Match) that was supplied by the client evaluates to false. That is, the client requested something and supplied preconditions, knowing full well that those preconditions might fail. 412 should never be sprung on the client out of the blue, and shouldn't be related to the request entity per se.

Ultimately, .keystore and .jks are just file extensions: it's up to you to name your files sensibly. Some application use a keystore file stored in $HOME/.keystore: it's usually implied that it's a JKS file, since JKS is the default keystore type in the Sun/Oracle Java security provider. Not everyone uses the .jks extension for JKS files, because it's implied as the default. I'd recommend using the extension, just to remember which type to specify (if you need).

In Java, the word keystore can have either of the following meanings, depending on the context:

• the API: http://docs.oracle.com/javase/6/docs/api/java/security/KeyStore.html
• a file (or other mechanism) that can be used to back this API
• a keystore as opposed to a truststore, as described here: https://stackoverflow.com/a/6341566/372643

When talking about the file and storage, this is not really a storage facility for key/value pairs (there are plenty or other formats for this). Rather, it's a container to store cryptographic keys and certificates (I believe some of them can also store passwords). Generally, these files are encrypted and password-protected so as not to let this data available to unauthorized parties.

Java uses its KeyStore class and related API to make use of a keystore (whether it's file based or not). JKS is a Java-specific file format, but the API can also be used with other file types, typically PKCS#12. When you want to load a keystore, you must specify its keystore type. The conventional extensions would be:

• .jks for type "JKS",
• .p12 or .pfx for type "PKCS12" (the specification name is PKCS#12, but the # is not used in the Java keystore type name).

In addition, BouncyCastle also provides its implementations, in particular BKS (typically using the .bks extension), which is frequently used for Android applications.

I came up against this problem too, and in trying to solve it I kept crashing the chrome tab that was running my app. It looks like the spread operator for objects was the culprit.

With a little help from adrianolsk’s comment and sidonaldson's answer above, I used Object.assign() the output of the spread operator from babel, like so:

this.options.map(option => {
  // New properties to be added
  const newPropsObj = {
    newkey1:value1,
    newkey2:value2
  };

  // Assign new properties and return
  return Object.assign(option, newPropsObj);
});

React components expose all the standard Javascript mouse events in their top-level interface. Of course, you can still use :hover in your CSS, and that may be adequate for some of your needs, but for the more advanced behaviors triggered by a hover you'll need to use the Javascript. So to manage hover interactions, you'll want to use onMouseEnter and onMouseLeave. You then attach them to handlers in your component like so:

<ReactComponent
    onMouseEnter={() => this.someHandler}
    onMouseLeave={() => this.someOtherHandler}
/>

You'll then use some combination of state/props to pass changed state or properties down to your child React components.

For those of you looking for a Swift 4 solution to this answer, you can use the following to detect a touch event on a UIImageView.

let gestureRecognizer: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageViewTapped))
imageView.addGestureRecognizer(gestureRecognizer)
imageView.isUserInteractionEnabled = true

You will then need to define your selector as follows:

@objc func imageViewTapped() {
    // Image has been tapped
}

One problem,everyone will face that is to Install Poppler.My way is a tricky way,but will work efficiently.1st download Poppler here.Then Extract it add In the code section just add poppler_path=r'C:\Program Files\poppler-0.68.0\bin'(for eg.) like below

from pdf2image import convert_from_path
images = convert_from_path("mypdf.pdf", 500,poppler_path=r'C:\Program Files\poppler-0.68.0\bin')
for i, image in enumerate(images):
    fname = 'image'+str(i)+'.png'
    image.save(fname, "PNG")

NeDB seems to be what you are looking for. From the blurb:

Embedded persistent database for Node.js, written in Javascript, with no dependency (except npm modules of course). You can think of it as a SQLite for Node.js projects, which can be used with a simple require statement. The API is a subset of MongoDB's. You can use it as a persistent or an in-memory only datastore.

Those are users. Check your /etc/passwd.

cd ~username takes you to that user's home directory.

Wrap an ArrayAdapter around your List<ScanResult>. Override getView() to populate your rows with the ScanResult data. Here is a free excerpt from one of my books that covers how to create custom ArrayAdapters like this.

When testing for directories remember that every directory contains two special files.

One is called '.' and the other '..'

. is the directory's own name while .. is the name of it's parent directory.

To avoid trailing backslash problems just test to see if the directory knows it's own name.

eg:

if not exist %temp%\buffer\. mkdir %temp%\buffer

This is probably a rare case, but for me a library that was included in the settings.gradle was not there.

E.g. I had: include ':libraries:Android-RateThisApp:library' in my settings.gradle

but the folder Android-RateThisApp was empty. As soon as I checked out this submodule the gradle sync succeed.

In simple words.

In Python you should add self argument as the first argument to all defined methods in classes:

class MyClass:
  def method(self, arg):
    print(arg)

Then you can use your method according to your intuition:

>>> my_object = MyClass()
>>> my_object.method("foo")
foo

This should solve your problem :)

For a better understanding, you can also read the answers to this question: What is the purpose of self?

It is true that there aren't "before triggers" in MSSQL. However, you could still track the changes that were made on the table, by using the "inserted" and "deleted" tables together. When an update causes the trigger to fire, the "inserted" table stores the new values and the "deleted" table stores the old values. Once having this info, you could relatively easy simulate the "before trigger" behaviour.

What about to split the string and strip words punctuation?

w in [ws.strip(',.?!') for ws in p.split()]

Or working the case:

w.lower() in [ws.strip(',.?!') for ws in p.lower().split()]

Maybe that way:

def wsearch(word, phrase):
    # Attention about punctuation and about split characters
    punctuation = ',.?!'
    return word.lower() in [words.strip(punctuation) for words in phrase.lower().split()]

Sample:

print(wsearch('CAr', 'I own a caR.'))
