Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.

An alternative option is to set it in the machine level web.config, so its not even in the web site folder.

To generate it do it just like the linked article in David's answer.

According to the documentation:

The WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions that follow it in the Dockerfile. If the WORKDIR doesn’t exist, it will be created even if it’s not used in any subsequent Dockerfile instruction.

Also, in the Docker best practices it recommends you to use it:

... you should use WORKDIR instead of proliferating instructions like RUN cd … && do-something, which are hard to read, troubleshoot, and maintain.

I would suggest to keep it.

I think you can refactor your Dockerfile to something like:

FROM node:latest
WORKDIR /usr/src/app
COPY package.json .
RUN npm install
COPY . ./
EXPOSE 3000
CMD [ “npm”, “start” ] 

It all boils down to maintainability. The best way to put this is whenever you use the new keyword to create an object, you're coupling the code that you're writing to an implementation.

The factory pattern lets you separate how you create an object from what you do with the object. When you create all of your objects using constructors, you are essentially hard-wiring the code that uses the object to that implementation. The code that uses your object is "dependent on" that object. This may not seem like a big deal on the surface, but when the object changes (think of changing the signature of the constructor, or subclassing the object) you have to go back and rewire things everywhere.

Today factories have largely been brushed aside in favor of using Dependency Injection because they require a lot of boiler-plate code that turns out to be a little hard to maintain itself. Dependency Injection is basically equivalent to factories but allows you to specify how your objects get wired together declaratively (through configuration or annotations).

var pass = new SecureString();
pass.AppendChar('s');
pass.AppendChar('e');
pass.AppendChar('c');
pass.AppendChar('r');
pass.AppendChar('e');
pass.AppendChar('t');
Process.Start("notepad", "admin", pass, "");

Works also with ProcessStartInfo:

var psi = new ProcessStartInfo
{
    FileName = "notepad",
    UserName = "admin",
    Domain = "",
    Password = pass,
    UseShellExecute = false,
    RedirectStandardOutput = true,
    RedirectStandardError = true
};
Process.Start(psi);

... on a Mac, Preferences' is under the main 'Aptana Studio 3' menu rather than the 'Windows' menu as mentioned above.

A pure python oneliner for cumulative sum:

cumsum = lambda X: X[:1] + cumsum([X[0]+X[1]] + X[2:]) if X[1:] else X

This is a recursive version inspired by recursive cumulative sums. Some explanations:

1. The first term X[:1] is a list containing the previous element and is almost the same as [X[0]] (which would complain for empty lists).
2. The recursive cumsum call in the second term processes the current element [1] and remaining list whose length will be reduced by one.
3. if X[1:] is shorter for if len(X)>1.

Test:

cumsum([4,6,12])
#[4, 10, 22]

cumsum([])
#[]

And simular for cumulative product:

cumprod = lambda X: X[:1] + cumprod([X[0]*X[1]] + X[2:]) if X[1:] else X

Test:

cumprod([4,6,12])
#[4, 24, 288]

usually we talking Maven Terminology about Group Id , Artifact Id and Snapshot Version

Group Id:identity of the group of the project Artifact Id:identity of the project Snapshot version:the version used by the project.

Artifact is nothing but some resulting file like Jar, War, Ear....

simply says Artifacts are nothing but packages.

Use the RegExp object constructor to create a regular expression from a string:

var re = new RegExp("a|b", "i");
// same as
var re = /a|b/i;

Use pyplot.text() (import matplotlib.pyplot as plt)

import matplotlib.pyplot as plt

x=[1,2,3]
y=[9,8,7]

plt.plot(x,y)
for a,b in zip(x, y): 
    plt.text(a, b, str(b))
plt.show()

This problem comes when you are writing data in many files simultaneously and your Operating System has a fixed limit of Open files. In Linux, you can increase the limit of open files.

How do I change the number of open files limit in Linux?

Note that, in addition to number of predictive variables, the Adjusted R-squared formula above also adjusts for sample size. A small sample will give a deceptively large R-squared.

Ping Yin & Xitao Fan, J. of Experimental Education 69(2): 203-224, "Estimating R-squared shrinkage in multiple regression", compares different methods for adjusting r-squared and concludes that the commonly-used ones quoted above are not good. They recommend the Olkin & Pratt formula.

However, I've seen some indication that population size has a much larger effect than any of these formulas indicate. I am not convinced that any of these formulas are good enough to allow you to compare regressions done with very different sample sizes (e.g., 2,000 vs. 200,000 samples; the standard formulas would make almost no sample-size-based adjustment). I would do some cross-validation to check the r-squared on each sample.

I think the only way of doing this in SQL-Server 2008R2 is to use a correlated subquery, or an outer apply:

SELECT  datekey,
        COALESCE(RunningTotal, 0) AS RunningTotal,
        COALESCE(RunningCount, 0) AS RunningCount,
        COALESCE(RunningDistinctCount, 0) AS RunningDistinctCount
FROM    document
        OUTER APPLY
        (   SELECT  SUM(Amount) AS RunningTotal,
                    COUNT(1) AS RunningCount,
                    COUNT(DISTINCT d2.dateKey) AS RunningDistinctCount
            FROM    Document d2
            WHERE   d2.DateKey <= document.DateKey
        ) rt;

This can be done in SQL-Server 2012 using the syntax you have suggested:

SELECT  datekey,
        SUM(Amount) OVER(ORDER BY DateKey) AS RunningTotal
FROM    document

However, use of DISTINCT is still not allowed, so if DISTINCT is required and/or if upgrading isn't an option then I think OUTER APPLY is your best option

Are you looking for something like this?

    COLUMN_NAMES=['A','B','C','D','E','F','G']
    df = pd.DataFrame(columns=COLUMN_NAMES)
    df.columns

   Index(['A', 'B', 'C', 'D', 'E', 'F', 'G'], dtype='object')

if you aren't yet using .net 4.5:

/// <summary>
/// TODO: AFTER WE UPGRADE TO .NET 4.5 THIS WILL NO LONGER BE NECESSARY.
/// </summary>
public class EmailAnnotation : RegularExpressionAttribute
{
    static EmailAnnotation()
    {
        DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(EmailAnnotation), typeof(RegularExpressionAttributeAdapter));
    }

    /// <summary>
    /// from: http://stackoverflow.com/a/6893571/984463
    /// </summary>
    public EmailAnnotation()
        : base(@"^[\w!#$%&'*+\-/=?\^_`{|}~]+(\.[\w!#$%&'*+\-/=?\^_`{|}~]+)*"
            + "@"
            + @"((([\-\w]+\.)+[a-zA-Z]{2,4})|(([0-9]{1,3}\.){3}[0-9]{1,3}))$") { }

    public override string FormatErrorMessage(string name)
    {
        return "E-mail is not valid";
    }
}

Then you can do this:

    public class ContactEmailAddressDto
    {
        public int ContactId { get; set; }
        [Required]
        [Display(Name = "New Email Address")]
        [EmailAnnotation] //**<----- Nifty.**
        public string EmailAddressToAdd { get; set; }
    }

Example: In a simple terms if you have a web service of calculator.

WSDL: WSDL tells about the functions that you can implement or exposed to the client. For example: add, delete, subtract and so on.

SOAP: Where as using SOAP you actually perform actions like doDelete(), doSubtract(), doAdd(). So SOAP and WSDL are apples and oranges. We should not compare them. They both have their own different functionality.

Why we use SOAP and WSDL: For platform independent data exchange.

EDIT: In a normal day to day life example:

WSDL: When we go to a restaurant we see the Menu Items, those are the WSDL's.

Proxy Classes: Now after seeing the Menu Items we make up our Mind (Process our mind on what to order): So, basically we make Proxy classes based on WSDL Document.

SOAP: Then when we actually order the food based on the Menu's: Meaning we use proxy classes to call upon the service methods which is done using SOAP. :)

Use extensions.

public static class NullableMixin {
    public static bool IsTrue(this System.Nullable<bool> val) {
        return val == true;
    }
    public static bool IsFalse(this System.Nullable<bool> val) {
        return val == false;
    }
    public static bool IsNull(this System.Nullable<bool> val) {
        return val == null;
    }
    public static bool IsNotNull(this System.Nullable<bool> val) {
        return val.HasValue;
    }
}


Nullable<bool> value = null;
if(value.IsTrue()) {
// do something with it
}

Best solution for this error when i tried some points. Follow this steps to solve this issue:

1. locate the file [XAMPP Installation Directory]\php\php.ini (e.g. C:\xampp\php\php.ini)
2. open php.ini in Notepad or any Text editor
3. locate the line containing max_execution_time and
4. increase the value from 30 to some larger number (e.g. set: max_execution_time = 90)
5. then restart Apache web server from the XAMPP control panel

In my case I received this exception even when all parameter values were correctly supplied but the type of command was not specified :

cmd.CommandType = System.Data.CommandType.StoredProcedure;

This is obviously not the case in the question above, but exception description is not very clear in this case, so I decided to specify that.

Rather than making a bunch of global variables, you might consider creating a class that has a bunch of public static constants. It's still global, but this way it's wrapped in a class so you know where the constant is coming from and that it's supposed to be a constant.

Constants.h

#ifndef CONSTANTS_H
#define CONSTANTS_H

class GlobalConstants {
  public:
    static const int myConstant;
    static const int myOtherConstant;
};

#endif

Constants.cpp

#include "Constants.h"

const int GlobalConstants::myConstant = 1;
const int GlobalConstants::myOtherConstant = 3;

Then you can use this like so:

#include "Constants.h"

void foo() {
  int foo = GlobalConstants::myConstant;
}

I haven't tested your code, just tried to help you understand how it operates in comment;

WITH
  cteReports (EmpID, FirstName, LastName, MgrID, EmpLevel)

The simplest example of a recursive CTE I can think of to illustrate its operation is;

;WITH Numbers AS
(
    SELECT n = 1
    UNION ALL
    SELECT n + 1
    FROM Numbers
    WHERE n+1 <= 10
)
SELECT n
FROM Numbers

Q 1) how value of N is getting incremented. if value is assign to N every time then N value can be incremented but only first time N value was initialize.

A1: In this case, N is not a variable. N is an alias. It is the equivalent of SELECT 1 AS N. It is a syntax of personal preference. There are 2 main methods of aliasing columns in a CTE in T-SQL. I've included the analog of a simple CTE in Excel to try and illustrate in a more familiar way what is happening.

--  Outside
;WITH CTE (MyColName) AS
(
    SELECT 1
)
-- Inside
;WITH CTE AS
(
    SELECT 1 AS MyColName
    -- Or
    SELECT MyColName = 1  
    -- Etc...
)

Q 2) now here about CTE and recursion of employee relation the moment i add two manager and add few more employee under second manager then problem start. i want to display first manager detail and in the next rows only those employee details will come those who are subordinate of that manager

A2:

Does this code answer your question?

All you have to do is create a subset of your dataframe where the isin method evaluates to False:

df = df[df['Column Name'].isin(['Value']) == False]

SELECT 
    ISNULL(currate.currentrate, 1)  
FROM ...

is less verbose than the winning answer and does the same thing

I have qt4 installed. I found that using the following path worked for me, despite 'which qmake' returning /usr/bin/qmake, which is just a link to qtchooser anyway.

The following path works for me, on a 64 bit system. Running from the full path of:

I wrote a mixin for some syntactic sugar ;)
Maybe someone likes this way of writing if-then-else better than using guards

depends on Less 1.7.0

https://github.com/pixelass/more-or-less/blob/master/less/fn/_if.less

Usage:

.if(isnumber(2), {
    .-then(){
        log {
            isnumber: true;
        }
    }
    .-else(){
        log {
            isnumber: false;
        }
    }
});

.if(lightness(#fff) gt (20% * 2), {
    .-then(){
        log {
            is-light: true;
        }
    }
});

using on example from above

.if(@debug, {
    .-then(){
        header {
            background-color: yellow;
            #title {
                background-color: orange;
            }
        }
        article {
            background-color: red;
        }
    }
});

By using a function:

def myloop():
    for i in range(1,6,1):  # 1st loop
        print('i:',i)
        for j in range(1,11,2):  # 2nd loop
            print('   i, j:' ,i, j)
            for k in range(1,21,4):  # 3rd loop
                print('      i,j,k:', i,j,k)
                if i%3==0 and j%3==0 and k%3==0:
                    return  # getting out of all loops

myloop()

Try running the above codes by commenting out the return as well.

Without using any function:

done = False
for i in range(1,6,1):  # 1st loop
    print('i:', i)
    for j in range(1,11,2):  # 2nd loop
        print('   i, j:' ,i, j)
        for k in range(1,21,4):  # 3rd loop
            print('      i,j,k:', i,j,k)
            if i%3==0 and j%3==0 and k%3==0:
                done = True
                break  # breaking from 3rd loop
        if done: break # breaking from 2nd loop
    if done: break     # breaking from 1st loop

Now, run the above codes as is first and then try running by commenting out each line containing break one at a time from the bottom.

I would imagine the safest way would just be to parse for <>s, no? Loop through the entire string, and copy anything not enclosed in <>s to a new string.

This CSS3 will make you line through property more easier, and working fine.

I was having the error in Hangfire where I did not have access to the internal workings of the library or was I able to trace what the primary cause was.

Building on @Remus Rusanu answer, I was able to have this fixed with the following script.

    --first set the database to single user mode
    ALTER DATABASE TransXSmartClientJob
    SET SINGLE_USER
    WITH ROLLBACK IMMEDIATE;
    GO

    -- Then try to repair
    DBCC CHECKDB(TransXSmartClientJob, REPAIR_REBUILD)

    -- when done, set the database back to multiple user mode
    ALTER DATABASE TransXSmartClientJob
    SET MULTI_USER;
    GO

I like to do this in case you ever need to pad with multiple characters or tags (e.g.  ) for display:

$.padStringLeft = function(s, pad, len) {
    if(typeof s !== 'undefined') {
        var c=s.length; while(len > c) {s=pad+s;c++;}
    }
    return s;
}    

$.padStringRight = function(s, pad, len) {
    if(typeof s !== 'undefined') {
        var c=s.length; while(len > c) {s += pad;c++;}
    }
    return s;
}

You can use the native map method for Arrays. map Method (Array) (JavaScript)

var myData = new Array(['2013-01-22', 0], ['2013-01-29', 0], ['2013-02-05', 0],
             ['2013-02-12', 0], ['2013-02-19', 0], ['2013-02-26', 0], 
             ['2013-03-05', 0], ['2013-03-12', 0], ['2013-03-19', 0], 
             ['2013-03-26', 0], ['2013-04-02', 21], ['2013-04-09', 2]);
var a = 0;
myData.map( function(aa){ a += aa[1];  return a; });

a is your result

There's software for content-based image retrieval, which does (partially) what you need. All references and explanations are linked from the project site and there's also a short text book (Kindle): LIRE

For Xcode 7, you have a much simpler solution. The only extra work is that you have to create a configuration plist file for exporting archive.

(Compared to Xcode 6, in the results of xcrun xcodebuild -help, -exportFormat and -exportProvisioningProfile options are not mentioned any more; the former is deleted, and the latter is superseded by -exportOptionsPlist.)

Step 1, change directory to the folder including .xcodeproject or .xcworkspace file.

cd MyProjectFolder

Step 2, use Xcode or /usr/libexec/PlistBuddy exportOptions.plist to create export options plist file. By the way, xcrun xcodebuild -help will tell you what keys you have to insert to the plist file.

Step 3, create .xcarchive file (folder, in fact) as follows(build/ directory will be automatically created by Xcode right now),

xcrun xcodebuild -scheme MyApp -configuration Release archive -archivePath build/MyApp.xcarchive

Step 4, export as .ipa file like this, which differs from Xcode6

xcrun xcodebuild -exportArchive -exportPath build/ -archivePath build/MyApp.xcarchive/ -exportOptionsPlist exportOptions.plist

Now, you get an ipa file in build/ directory. Just send it to apple App Store.

By the way, the ipa file created by Xcode 7 is much larger than by Xcode 6.

In js you can change zoom by

document.body.style.zoom="90%"

But it doesn't work in FF http://caniuse.com/#search=zoom

For ff you can try

-moz-transform: scale(0.9);

And check next topic How can I zoom an HTML element in Firefox and Opera?

#include<stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main()
{
    // Create a child process     
    int pid = fork();

    if (pid > 0)
    {

            int j=getpid();

            printf("in parent process %d\n",j);
    }
    // Note that pid is 0 in child process
    // and negative if fork() fails
    else if (pid == 0)
    {





            int i=getppid();
            printf("Before sleep %d\n",i);

            sleep(5);
            int k=getppid();

            printf("in child process %d\n",k);
    }

    return 0;

}

Typically one would use an auxiliary numbers table you usually keep around for just this purpose with some variation on this:

SELECT *
FROM (
    SELECT DATEADD(d, number - 1, '2009-01-01') AS dt
    FROM Numbers
    WHERE number BETWEEN 1 AND DATEDIFF(d, '2009-01-01', '2009-01-13') + 1
) AS DateRange
LEFT JOIN YourStuff
    ON DateRange.dt = YourStuff.DateColumn

I've seen variations with table-valued functions, etc.

You can also keep a permanent list of dates. We have that in our data warehouse as well as a list of times of day.

Creating a .bashrc file in your home directory also works. That way you don't have to copy your .bash_profile every time you install a new version of git bash.

If you set a breakpoint, you can paste this into the debugger to print the view hierarchy:

po [[UIWindow keyWindow] recursiveDescription]

You should be able to find your view's parent somewhere in that mess :)

You can try this method that is developed by Chucai Yi and Yingli Tian.

They also share a software (which is based on Opencv-1.0 and it should run under Windows platform.) that you can use (though no source code available). It will generate all the text bounding boxes (shown in color shadows) in the image. By applying to your sample images, you will get the following results:

Note: to make the result more robust, you can further merge adjacent boxes together.

Update: If your ultimate goal is to recognize the texts in the image, you can further check out gttext, which is an OCR free software and Ground Truthing tool for Color Images with Text. Source code is also available.

With this, you can get recognized texts like:

if (!$("#myTextArea").val()) {
    // textarea is empty
}

You can also use $.trim to make sure the element doesn't contain only white-space:

if (!$.trim($("#myTextArea").val())) {
    // textarea is empty or contains only white-space
}

According to SVG spec, alignment-baseline only applies to <tspan>, <textPath>, <tref> and <altGlyph>. My understanding is that it is used to offset those from the <text> object above them. I think what you are looking for is dominant-baseline.

Possible values of dominant-baseline are:

auto | use-script | no-change | reset-size | ideographic | alphabetic | hanging | mathematical | central | middle | text-after-edge | text-before-edge | inherit

Check the W3C recommendation for the dominant-baseline property for more information about each possible value.

ER/Studio by Embarcadero is one of the costlier ones, but the hierarchical mode it present is by far the best one for understanding database models. It makes query writing the easiest task in the world.

It also is incredible with normalization, denormalization, warehousing, documentation, etc.

The downside is that it is a pretty expensive tool especially when you go multiplatform.

Here is another way to reproduce this error in Python2.7 with numpy:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate(a,b)   #note the lack of tuple format for a and b
print(c) 

The np.concatenate method produces an error:

TypeError: only length-1 arrays can be converted to Python scalars

If you read the documentation around numpy.concatenate, then you see it expects a tuple of numpy array objects. So surrounding the variables with parens fixed it:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate((a,b))  #surround a and b with parens, packaging them as a tuple
print(c) 

Then it prints:

[1 2 3 4 5 6]

What's going on here?

That error is a case of bubble-up implementation - it is caused by duck-typing philosophy of python. This is a cryptic low-level error python guts puke up when it receives some unexpected variable types, tries to run off and do something, gets part way through, the pukes, attempts remedial action, fails, then tells you that "you can't reformulate the subspace responders when the wind blows from the east on Tuesday".

In more sensible languages like C++ or Java, it would have told you: "you can't use a TypeA where TypeB was expected". But Python does it's best to soldier on, does something undefined, fails, and then hands you back an unhelpful error. The fact we have to be discussing this is one of the reasons I don't like Python, or its duck-typing philosophy.

Use /config.php.

For Java programmers using Spring, I've avoided this problem using an AOP aspect that automatically retries transactions that run into transient deadlocks.

See @RetryTransaction Javadoc for more info.

I have found that "get-task-allow" needs to be checked for Development builds but unchecked for Distribution builds. The easiest way to accomplish this (AFAIK) is to have two entitlements files in your project: Entitlements.plist and EntitlementsDebug.plist - and to reference the proper one in the build project settings for the various configurations in your project.

Tools -> Options -> Fonts & Colors -> then click on Font browse option. Now you will see a popup box. Here you can change Font:, Font Style: and Size:

I had tested it.

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

Interactively, you can display it with

help(my_func)

Or from code you can retrieve it with

my_func.__doc__

Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".

>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World

Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.

Think of it like an archive. MyDB.Bak contains MyDB.mdf and MyDB.ldf.

Restore with Move to say HerDB basically grabs MyDB.mdf (and ldf) from the back up, and copies them as HerDB.mdf and ldf.

So if you already had a MyDb on the server instance you are restoring to it wouldn't be touched.

Math.round

This method works well for me. I use ISNULL() for the primary key field, and COALESCE() if the field should not be the primary key, but should also have a non-nullable value. This example yields ID field with a non-nullable primary key. The other fields are not keys, and have (None) as their Nullable attribute.

SELECT      
ISNULL(P.ID, - 1) AS ID,  
COALESCE (P.PurchaseAgent, U.[User Nickname]) AS PurchaseAgent,  
COALESCE (P.PurchaseAuthority, 0) AS PurchaseAuthority,  
COALESCE (P.AgencyCode, '') AS AgencyCode,  
COALESCE (P.UserID, U.ID) AS UserID,  
COALESCE (P.AssignPOs, 'false') AS AssignPOs,  
COALESCE (P.AuthString, '') AS AuthString,  
COALESCE (P.AssignVendors, 'false') AS AssignVendors 
FROM Users AS U  
INNER JOIN Users AS AU ON U.Login = AU.UserName  
LEFT OUTER JOIN PurchaseAgents AS P ON U.ID = P.UserID

if you really don't have a primary key, you can spoof one by using ROW_NUMBER to generate a pseudo-key that is ignored by your code. For example:

SELECT
ROW_NUMBER() OVER(ORDER BY A,B) AS Id,
A, B
FROM SOMETABLE

Not sure what you are really after but if you want to print exactly what you have you can do:

Option 1

print(df['Item'].to_csv(index=False))

Sweet
Candy
Chocolate

Option 2

for v in df['Item']:
    print(v)

Sweet
Candy
Chocolate

Keeping your code human readable not just machine readable. A lot of devices still can only show 80 characters at a time. Also it makes it easier for people with larger screens to multi-task by being able to set up multiple windows to be side by side.

Readability is also one of the reasons for enforced line indentation.

No one seems to have mentioned about the negative infinity explicitly, so I think I should add it.

For negative infinity:

-math.inf

For positive infinity (just for the sake of completeness):

math.inf

If I am responsible for the 'live' site I better be aware of everything that is going on and into my site. For that reason I host the jquery-min version myself either on the same server or a static/external server but either way a location where only I (or my program/proxy) can update the library after having verified/tested every change

Per numpy docs:

When operating on two arrays, NumPy compares their shapes element-wise. It starts with the trailing dimensions, and works its way forward. Two dimensions are compatible when:

• they are equal, or
• one of them is 1

In other words, if you are trying to multiply two matrices (in the linear algebra sense) then you want X.dot(y) but if you are trying to broadcast scalars from matrix y onto X then you need to perform X * y.T.

Example:

>>> import numpy as np
>>>
>>> X = np.arange(8).reshape(4, 2)
>>> y = np.arange(2).reshape(1, 2)  # create a 1x2 matrix
>>> X * y
array([[0,1],
       [0,3],
       [0,5],
       [0,7]])

.newLine() is the best if your system property line.separator is proper . and sometime you don't want to change the property runtime . So alternative solution is appending \n

Actually, you can use what Google provides via the support library RoundedBitmapDrawableFactory class (here and here), instead of using a third party library :

Gradle:

implementation 'androidx.appcompat:appcompat:1.0.0-beta01'

MainActivity.kt

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val originalDrawable = ContextCompat.getDrawable(this, R.drawable.avatar_1)!!
        val bitmap = convertDrawableToBitmap(originalDrawable)
        val drawable = RoundedBitmapDrawableFactory.create(resources, bitmap)
        drawable.setAntiAlias(true)
        drawable.cornerRadius = Math.max(bitmap.width, bitmap.height) / 2.0f
        avatarImageView.setImageDrawable(drawable)
    }

    companion object {
        @JvmStatic
        fun convertDrawableToBitmap(drawable: Drawable): Bitmap {
            if (drawable is BitmapDrawable)
                return drawable.bitmap
            // We ask for the bounds if they have been set as they would be most
            // correct, then we check we are  > 0
            val bounds = drawable.bounds
            val width = if (!bounds.isEmpty) bounds.width() else drawable.intrinsicWidth
            val height = if (!bounds.isEmpty) bounds.height() else drawable.intrinsicHeight
            // Now we check we are > 0
            val bitmap = Bitmap.createBitmap(if (width <= 0) 1 else width, if (height <= 0) 1 else height,
                    Bitmap.Config.ARGB_8888)
            val canvas = Canvas(bitmap)
            drawable.setBounds(0, 0, canvas.width, canvas.height)
            drawable.draw(canvas)
            return bitmap
        }
    }
}

The result:

And, suppose you want to add a border on top of it, you can use this for example:

stroke_drawable.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <stroke
        android:width="4dp" android:color="@android:color/black"/>
</shape>

And add android:foreground="@drawable/stroke_drawable" to the ImageView in the layout XML file, and you get this :

I'm not sure how to add shadow (that will work on older Android versions), though. Using FloatingActionButton (from the "com.google.android.material:material" dependency), I failed to make the bitmap fill the FAB itself. Using it instead could be even better if it worked.

EDIT: if you wish to add shadow of elevation (available from API 21), you can change a bit what I wrote:

Inside the layout XML file:

<androidx.appcompat.widget.AppCompatImageView android:padding="4dp"
    android:id="@+id/avatarImageView" android:layout_width="100dp" android:layout_height="100dp" android:elevation="8dp"
    android:layout_gravity="center" android:background="@drawable/stroke_drawable" tools:srcCompat="@drawable/avatar_1"/>

CircularShadowViewOutlineProvider.kt

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
class CircularShadowViewOutlineProvider : ViewOutlineProvider() {
    override fun getOutline(view: View, outline: Outline) {
        val size = Math.max(view.width, view.height)
        outline.setRoundRect(0, 0, size, size, size / 2f)
    }
}

In code:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
        avatarImageView.outlineProvider = CircularShadowViewOutlineProvider()

Result:

In Java 9 the version 1 should be faster because it is converted to invokedynamic call. More details can be found in JEP-280:

The idea is to replace the entire StringBuilder append dance with a simple invokedynamic call to java.lang.invoke.StringConcatFactory, that will accept the values in the need of concatenation.

Continuing this answer, There is another difference that if you want your method to return different values for example when it is first time called, second time called etc then you can pass values so for example...

PowerMockito.doReturn(false, false, true).when(SomeClass.class, "SomeMethod", Matchers.any(SomeClass.class));

So it will return false when the method is called in same test case and then it will return false again and lastly true.

I use @gnarf's method, though I fall back on document.writelning a <script> tag for IE<7 as I couldn't get DOM creation to work reliably in IE6 (and TBH didn't care enough to put much effort into it). The core of my code is:

if (horus.script.broken) {
    document.writeln('<script type="text/javascript" src="'+script+'"></script>');   
    horus.script.loaded(script);
} else {
    var s=document.createElement('script');
    s.type='text/javascript';
    s.src=script;
    s.async=true;

    if (horus.brokenDOM){
        s.onreadystatechange=
            function () {
                if (this.readyState=='loaded' || this.readyState=='complete'){
                    horus.script.loaded(script);
                }
        }
    }else{
        s.onload=function () { horus.script.loaded(script) };
    }

    document.head.appendChild(s);
}

where horus.script.loaded() notes that the javascript file is loaded, and calls any pending uncalled routines (saved by autoloader code).

If you have created CMS block named 'block_identifier' from admin panel. Then following will be code to call them in .phtml

<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('block_identifier')->toHtml(); 
?> 

You can also try this one

Matrix matrix = new Matrix();

matrix.postRotate(90);

Bitmap scaledBitmap = Bitmap.createScaledBitmap(bitmapOrg, width, height, true);

Bitmap rotatedBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0, scaledBitmap.getWidth(), scaledBitmap.getHeight(), matrix, true);

Then you can use the rotated image to set in your imageview through

imageView.setImageBitmap(rotatedBitmap);

LogisticRegression is not for regression but classification !

The Y variable must be the classification class,

(for example 0 or 1)

And not a continuous variable,

that would be a regression problem.

If you already have material-icons working in your web project, just need to update your reference in the html file and the used class for icons:

html reference:

Before

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet" />

After

<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp"
rel="stylesheet" />

material icons class:

After that just check wich className are you using:

Before:

<i className="material-icons">weekend</i>

After:

<i className="material-icons-outlined">weekend</i>

that works for me... Pura vida!

Database Clustering is actually a mode of synchronous replication between two or possibly more nodes with an added functionality of fault tolerance added to your system, and that too in a shared nothing architecture. By shared nothing it means that the individual nodes actually don't share any physical resources like disk or memory.

As far as keeping the data synchronized is concerned, there is a management server to which all the data nodes are connected along with the SQL node to achieve this(talking specifically about MySQL).

Now about the differences: load balancing is just one result that could be achieved through clustering, the others include high availability, scalability and fault tolerance.

You can use it by easy way, through store method in your controller

like the below

First, we must create a form with file input to let us upload our file.

{{Form::open(['route' => 'user.store', 'files' => true])}}

{{Form::label('user_photo', 'User Photo',['class' => 'control-label'])}}
{{Form::file('user_photo')}}
{{Form::submit('Save', ['class' => 'btn btn-success'])}}

{{Form::close()}}

Here is how we can handle file in our controller.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class UserController extends Controller
{

  public function store(Request $request)
  {

  // get current time and append the upload file extension to it,
  // then put that name to $photoName variable.
  $photoName = time().'.'.$request->user_photo->getClientOriginalExtension();

  /*
  talk the select file and move it public directory and make avatars
  folder if doesn't exsit then give it that unique name.
  */
  $request->user_photo->move(public_path('avatars'), $photoName);

  }
}

That’s it. Now you can save the $photoName to the database as a user_photo field value. You can use asset(‘avatars’) function in your view and access the photos.

Let's, just as example:

public class Test {     public Test() {         System.out.println("NO ARGS");     }      public Test(String s) {         this();         System.out.println("1 ARG");     }      public static void main(String args[])     {         Test t = new Test("s");     } } 

It will print

>>> NO ARGS >>> 1 ARG 

The correct way to call the constructor is by:

this(); 

uniq should do fine if you're file is/can be sorted, if you can't sort the file for some reason you can use awk:

awk '{a[$0]++}END{for(i in a)if(a[i]<2)print i}'

Also, if you don't have the gradlew file in your current directory:

You can install gradle with homebrew with the following command:

$ brew install gradle

As mentioned in this answer. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):

$ gradle test 

It's also a common convention to use with the first argument of the test method from Kernel#test

irb(main):001:0> test ?d, "/dev" # directory exists?
=> true
irb(main):002:0> test ?-, "/etc/hosts", "/etc/hosts" # are the files identical
=> true

as seen in this question here

Put the default value in single quote and it will work as intended. An example of migration:

$table->increments('id');
            $table->string('name');
            $table->string('url');
            $table->string('country');
            $table->tinyInteger('status')->default('1');
            $table->timestamps();

EDIT : in your case ->default('100.0');

I have the same need and use a generic method (inside an ArrayUtils class):

public static <T> String[] toStringArray(T[] array) {
    String[] result=new String[array.length];
    for(int i=0; i<array.length; i++){
        result[i]=array[i].toString();
    }
    return result;
}

And just define a STATIC inside the enum...

public static final String[] NAMES = ArrayUtils.toStringArray(values());

Java enums really miss a names() and get(index) methods, they are really helpful.

You may want to look at Tibbo VSPDL for creating a linux virtual serial port using a Kernel driver -- it seems pretty new, and is available for download right now (beta version). Not sure about the license at this point, or whether they want to make it available commercially only in the future.

There are other commercial alternatives, such as http://www.ttyredirector.com/.

In Open Source, Remserial (GPL) may also do what you want, using Unix PTY's. It transmits the serial data in "raw form" to a network socket; STTY-like setup of terminal parameters must be done when creating the port, changing them later like described in RFC 2217 does not seem to be supported. You should be able to run two remserial instances to create a virtual nullmodem like com0com, except that you'll need to set up port speed etc in advance.

Socat (also GPL) is like an extended variant of Remserial with many many more options, including a "PTY" method for redirecting the PTY to something else, which can be another instance of Socat. For Unit tets, socat is likely nicer than remserial because you can directly cat files into the PTY. See the PTY example on the manpage. A patch exists under "contrib" to provide RFC2217 support for negotiating serial line settings.

From what I understand you are trying to print an ArrayList of arrays and one way to display that would be

System.out.println(Arrays.deepToString(list.toArray()));

One option that is available is fooTable. Works great on a Responsive website and allows you to set multiple breakpoints... fooTable Link

If c is a set then you can check whether it's empty by doing: return not c.

If c is empty then not c will be True.

Otherwise, if c contains any elements not c will be False.

Get back to the default setting by following this step:

Instead of

$cfg['Servers'][$i]['AllowNoPassword'] = false;

change it to:

$cfg['Servers'][$i]['AllowNoPassword'] = true;

in your config.inc.php file.

Do not specify any password and put the user name as it was before, which means root.

E.g.

$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';

This worked for me after i had edited my config.inc.php file.

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.

Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.

The best documentation you'll find on the topic is the virtual host documentation in the apache manual.

There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.

The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost entry for each port.

Assuming you're starting from scratch, this is much simpler than it may seem.

If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.

NameVirtualHost *:80

If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost directive, and it will be removed in a future version.

Now your vhost definitions:

<VirtualHost *:80>
    DocumentRoot "/home/user/site1/"
    ServerName site1
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/home/user/site2/"
    ServerName site2
</VirtualHost>

You can run as many sites as you want on the same port. The ServerName being different is enough to tell Apache which vhost to use. Also, the ServerName directive is always the domain/hostname and should never include a path.

If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81

You could use this plugin which creates a form, and submits it, then removes it from the page.

jQuery.download = function(url, data, method) {
    //url and data options required
    if (url && data) {
        //data can be string of parameters or array/object
        data = typeof data == 'string' ? data : jQuery.param(data);
        //split params into form inputs
        var inputs = '';
        jQuery.each(data.split('&'), function() {
            var pair = this.split('=');
            inputs += '<input type="hidden" name="' + pair[0] +
                '" value="' + pair[1] + '" />';
        });
        //send request
        jQuery('<form action="' + url +
                '" method="' + (method || 'post') + '">' + inputs + '</form>')
            .appendTo('body').submit().remove();
    };
};


$.download(
    '/export.php',
    'filename=mySpreadsheet&format=xls&content=' + spreadsheetData
);

This worked for me. Found this plugin here

To get your program to run, please put jsp files under web-content and not under WEB-INF because in Eclipse the files are not accessed there by the server, so try starting the server and browsing to URL:

http://localhost:8080/YourProject/yourfile.jsp

then your problem will be solved.

you can use cssSelector,

driver.switchTo().frame(driver.findElement(By.cssSelector("iframe[title='Fill Quote']")));

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

Try getting Spring to inject it, assuming you're using Spring as a dependency-injection framework.

In your class, do something like this:

public void setSqlResource(Resource sqlResource) {
    this.sqlResource = sqlResource;
}

And then in your application context file, in the bean definition, just set a property:

<bean id="someBean" class="...">
    <property name="sqlResource" value="classpath:com/somecompany/sql/sql.txt" />
</bean>

And Spring should be clever enough to load up the file from the classpath and give it to your bean as a resource.

You could also look into PropertyPlaceholderConfigurer, and store all your SQL in property files and just inject each one separately where needed. There are lots of options.

If using the following HTML:

<button id="submit-button"></button>

Style can be applied through JS using the style object available on an HTMLElement.

To set height and width to 200px of the above example button, this would be the JS:

var myButton = document.getElementById('submit-button');
myButton.style.height = '200px';
myButton.style.width= '200px';

I believe with this method, you are not directly writing CSS (inline or external), but using JavaScript to programmatically alter CSS Declarations.

Getting one char from string at specified index

Dim pos As Integer
Dim outStr As String
pos = 2 
Dim outStr As String
outStr = Left(Mid("abcdef", pos), 1)

outStr="b"

To avoid syntax errors, be sure to always put BEGIN and END after an IF clause, eg:

IF (@A!= @SA)
   BEGIN
   --do stuff
   END
IF (@C!= @SC)
   BEGIN
   --do stuff
   END

... and so on. This should work as expected. Imagine BEGIN and END keyword as the opening and closing bracket, respectively.

According to the source code of codeigniter, the function set is defined as:

public function set($key, $value = '', $escape = TRUE)
{
    $key = $this->_object_to_array($key);

    if ( ! is_array($key))
    {
        $key = array($key => $value);
    }

    foreach ($key as $k => $v)
    {
        if ($escape === FALSE)
        {
            $this->ar_set[$this->_protect_identifiers($k)] = $v;
        }
        else
        {
            $this->ar_set[$this->_protect_identifiers($k, FALSE, TRUE)] = $this->escape($v);
        }
    }

    return $this;
}

Apparently, if $key is an array, codeigniter will simply ignore the second parameter $value, but the third parameter $escape will still work throughout the iteration of $key, so in this situation, the following codes work (using the chain method):

$this->db->set(array(
    'name' => $name ,
    'email' => $email,
    'time' => 'NOW()'), '', FALSE)->insert('mytable');

However, this will unescape all the data, so you can break your data into two parts:

$this->db->set(array(
    'name' => $name ,
    'email' => $email))->set(array('time' => 'NOW()'), '', FALSE)->insert('mytable');

Another way to achieve this is to add a class .btn-space in your buttons

  <button type="button" class="btn btn-outline-danger btn-space"
  </button>
  <button type="button" class="btn btn-outline-primary btn-space"
  </button>

and define this class as follows

.btn-space {
    margin-right: 15px;
}

Radio button set checked through jquery:

<div id="somediv" >
 <input type="radio" name="enddate" value="1"  />
 <input type="radio" name="enddate" value="2"  />
 <input type="radio" name="enddate" value="3"  />
</div>

jquery code:

$('div#somediv input:radio:nth(0)').attr("checked","checked");

Not sure it stands for anything special. It's just a convention that you supply an 'all' rule, and generally it's used to list all the sub-targets needed to build the entire project, hence the name 'all'. The only thing special about it is that often times people will put it in as the first target in the makefile, which means that just typing 'make' alone will do the same thing as 'make all'.

If using PhpStorm 2019 and higher

File > Settings > Editor > General

There is'Soft-warp files' input under the 'Soft Warps' Header.

*.md; *.txt; *.rst; .adoc;

Add the file types to this field in which files you want them to be used.

*.md; *.txt; *.rst; .adoc;.php;*.js

You can also simply use

WORKDIR /var/www/app

It will automatically create the folders if they don't exist.

Then switch back to the directory you need to be in.

Since $http.get returns a 'promise' with the extra convenience methods success and error (which just wrap the result of then) you should be able to use (regardless of your Angular version):

$http.get('/someUrl')
    .then(function success(response) {
        console.log('succeeded', response); // supposed to have: data, status, headers, config, statusText
    }, function error(response) {
        console.log('failed', response); // supposed to have: data, status, headers, config, statusText
    })

Not strictly an answer to the question, but if you're getting bitten by the "my version of Angular is different than the docs" issue you can always dump all of the arguments, even if you don't know the appropriate method signature:

$http.get('/someUrl')
  .success(function(data, foo, bar) {
    console.log(arguments); // includes data, status, etc including unlisted ones if present
  })
  .error(function(baz, foo, bar, idontknow) {
    console.log(arguments); // includes data, status, etc including unlisted ones if present
  });

Then, based on whatever you find, you can 'fix' the function arguments to match.

Caller-saved registers (AKA volatile registers, or call-clobbered) are used to hold temporary quantities that need not be preserved across calls.

For that reason, it is the caller's responsibility to push these registers onto the stack or copy them somewhere else if it wants to restore this value after a procedure call.

It's normal to let a call destroy temporary values in these registers, though.

Callee-saved registers (AKA non-volatile registers, or call-preserved) are used to hold long-lived values that should be preserved across calls.

When the caller makes a procedure call, it can expect that those registers will hold the same value after the callee returns, making it the responsibility of the callee to save them and restore them before returning to the caller. Or to not touch them.

Here is how I did it:

START=$(date +%s);
sleep 1; # Your stuff
END=$(date +%s);
echo $((END-START)) | awk '{print int($1/60)":"int($1%60)}'

Really simple, take the number of seconds at the start, then take the number of seconds at the end, and print the difference in minutes:seconds.

You can set a bucket policy as detailed in this blog post:

http://ariejan.net/2010/12/24/public-readable-amazon-s3-bucket-policy/

As per @robbyt's suggestion, create a bucket policy with the following JSON:

{
  "Version": "2008-10-17",
  "Statement": [{
    "Sid": "AllowPublicRead",
    "Effect": "Allow",
    "Principal": { "AWS": "*" },
    "Action": ["s3:GetObject"],
    "Resource": ["arn:aws:s3:::bucket/*" ]
  }]
}

Important: replace bucket in the Resource line with the name of your bucket.

Simply use the checked property of the checkAll and use use prop() instead of attr for checked property

Live Demo

 $('#checkAll').click(function () {    
     $('input:checkbox').prop('checked', this.checked);    
 });

Use prop() instead of attr() for properties like checked

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method

You have same id for checkboxes and its should be unique. You better use some class with the dependent checkboxes so that it does not include the checkboxes you do not want. As $('input:checkbox') will select all checkboxes on the page. If your page is extended with new checkboxes then they will also get selected/un-selected. Which might not be the intended behaviour.

Live Demo

$('#checkAll').click(function () {    
    $(':checkbox.checkItem').prop('checked', this.checked);    
});

I've mixed and matched from different schemes I've seen and based on the tooling I'm using.
So my completed branch name would be:

name/feature/issue-tracker-number/short-description

which would translate to:

mike/blogs/RSSI-12/logo-fix

The parts are separated by forward slashes because those get interpreted as folders in SourceTree for easy organization. We use Jira for our issue tracking so including the number makes it easier to look up in the system. Including that number also makes it searchable when trying to find that issue inside Github when trying to submit a pull request.

When you use QDir.mkpath() it returns true if the path already exists, in the other hand QDir.mkdir() returns false if the path already exists. So depending on your program you have to choose which fits better.

You can see more on Qt Documentation

You can use JsonResponse with values. Simple example:

from django.http import JsonResponse

def some_view(request):
    data = list(SomeModel.objects.values())  # wrap in list(), because QuerySet is not JSON serializable
    return JsonResponse(data, safe=False)  # or JsonResponse({'data': data})

Or another approach with Django's built-in serializers:

from django.core import serializers
from django.http import HttpResponse

def some_view(request):
    qs = SomeModel.objects.all()
    qs_json = serializers.serialize('json', qs)
    return HttpResponse(qs_json, content_type='application/json')

In this case result is slightly different (without indent by default):

[
    {
        "model": "some_app.some_model",
        "pk": 1,
        "fields": {
            "name": "Elon",
            "age": 48,
            ...
        }
    },
    ...
]

I have to say, it is good practice to use something like marshmallow to serialize queryset.

...and a few notes for better performance:

• use pagination if your queryset is big;
• use objects.values() to specify list of required fields to avoid serialization and sending to client unnecessary model's fields (you also can pass fields to serializers.serialize);

You should issue HEAD requests, not GET one, because you don't need the URI contents at all. As Pies said above, you should check for status code (in 200-299 ranges, and you may optionally follow 3xx redirects).

The answers question contain a lot of code examples which may be helpful: PHP / Curl: HEAD Request takes a long time on some sites

I am going to drop in my two cents for what I use opcache.

I have made an extensive framework with a lot of fields and validation methods and enums to be able to talk to my database.

Without opcache

When using this script without opcache and I push 9000 requests in 2.8 seconds to the apache server it maxes out at 90-100% cpu for 70-80 seconds until it catches up with all the requests.

Total time taken: 76085 milliseconds(76 seconds)

With opcache enabled

With opcache enabled it runs at 25-30% cpu time for about 25 seconds and never passes 25% cpu use.

Total time taken: 26490 milliseconds(26 seconds)

I have made an opcache blacklist file to disable the caching of everything except the framework which is all static and doesnt need changing of functionality. I choose explicitly for just the framework files so that I could develop without worrying about reloading/validating the cache files. Having everything cached saves a second on the total of the requests 25546 milliseconds

This significantly expands the amount of data/requests I can handle per second without the server even breaking a sweat.

Two options, either reference the new jars in your classpath or unpack all classes in the enclosing jars and re-jar the whole lot! As far as I know packaging jars within jars is not recommeneded and you'll forever have the class not found exception!

Note that if you've merged remote branches or have local commits and want to go back to the remote HEAD you must do:

git reset --hard origin/HEAD

HEAD alone will only refer to the local commit/merge -- several times I have forgotten that when resetting and end up with "your repository is X commits ahead.." when I fully intended to nuke ALL changes/commits and return to the remote branch.

Before using reset think about using revert so you can always go back.

git reset vs git revert   sonic0002        2019-02-02 08:26:39 

When maintaining code using version control systems such as git, it is unavoidable that we need to rollback some wrong commits either due to bugs or temp code revert. In this case, rookie developers would be very nervous because they may get lost on what they should do to rollback their changes without affecting others, but to veteran developers, this is their routine work and they can show you different ways of doing that. In this post, we will introduce two major ones used frequently by developers.

• git reset
• git revert

What are their differences and corresponding use cases? We will discuss them in detail below. git reset Assuming we have below few commits.

Commit A and B are working commits, but commit C and D are bad commits. Now we want to rollback to commit B and drop commit C and D. Currently HEAD is pointing to commit D 5lk4er, we just need to point HEAD to commit B a0fvf8 to achieve what we want.  It's easy to use git reset command.

git reset --hard a0fvf8

After executing above command, the HEAD will point to commit B.

But now the remote origin still has HEAD point to commit D, if we directly use git push to push the changes, it will not update the remote repo, we need to add a -f option to force pushing the changes.

git push -f

The drawback of this method is that all the commits after HEAD will be gone once the reset is done. In case one day we found that some of the commits ate good ones and want to keep them, it is too late. Because of this, many companies forbid to use this method to rollback changes.

git revert The use of git revert is to create a new commit which reverts a previous commit. The HEAD will point to the new reverting commit.  For the example of git reset above, what we need to do is just reverting commit D and then reverting commit C. 

git revert 5lk4er
git revert 76sdeb

Now it creates two new commit D' and C', 

In above example, we have only two commits to revert, so we can revert one by one. But what if there are lots of commits to revert? We can revert a range indeed.

git revert OLDER_COMMIT^..NEWER_COMMIT

This method would not have the disadvantage of git reset, it would point HEAD to newly created reverting commit and it is ok to directly push the changes to remote without using the -f option. Now let's take a look at a more difficult example. Assuming we have three commits but the bad commit is the second commit. 

It's not a good idea to use git reset to rollback the commit B since we need to keep commit C as it is a good commit. Now we can revert commit C and B and then use cherry-pick to commit C again. 

From above explanation, we can find out that the biggest difference between git reset and git revert is that git reset will reset the state of the branch to a previous state by dropping all the changes post the desired commit while git revert will reset to a previous state by creating new reverting commits and keep the original commits. It's recommended to use git revert instead of git reset in enterprise environment.  Reference: https://kknews.cc/news/4najez2.html

An elegant recursive solution that corresponds to the best answer explanation above. The core vector operation is only 4 lines. credit to "Guide to Competitive Programming" book from Laaksonen, Antti.

// #include <iostream>
#include <vector>
using namespace std;

vector<int> subset;
void search(int k, int n) {
    if (k == n+1) {
    // process subset - put any of your own application logic
    // for (auto i : subset) cout<< i << " ";
    // cout << endl;
    }
    else {
        // include k in the subset
        subset.push_back(k);
        search(k+1, n);
        subset.pop_back();
        // don't include k in the subset
        search(k+1,n);
    }
}

int main() {
    // find all subset between [1,3]
    search(1, 3);
}

Requests natively supports basic auth only with user-pass params, not with tokens.

You could, if you wanted, add the following class to have requests support token based basic authentication:

import requests
from base64 import b64encode

class BasicAuthToken(requests.auth.AuthBase):
    def __init__(self, token):
        self.token = token
    def __call__(self, r):
        authstr = 'Basic ' + b64encode(('token:' + self.token).encode('utf-8')).decode('utf-8')
        r.headers['Authorization'] = authstr
        return r

Then, to use it run the following request :

r = requests.get(url, auth=BasicAuthToken(api_token))

An alternative would be to formulate a custom header instead, just as was suggested by other users here.

    char[] word = {'a', 'b', 'c', 'b', 'a' };
    System.out.println(isPalindrome(word, 0, word.length - 1));
    System.out.println(isPalindrome(word));
}

Look at the r.status_code attribute:

if r.status_code == 404:
    # A 404 was issued.

Demo:

>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404

If you want requests to raise an exception for error codes (4xx or 5xx), call r.raise_for_status():

>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "requests/models.py", line 664, in raise_for_status
    raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.

You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:

if r:
    # successful response

If you want to be more explicit, use if r.ok:.

Well presumably it's not using the same version of Java when running it externally. Look through the startup scripts carefully to find where it picks up the version of Java to run. You should also check the startup logs to see whether they indicate which version is running.

Alternatively, unless you need the Java 7 features, you could always change your compiler preferences in Eclipse to target 1.6 instead.

Similar to Tamas's answer, here is a one-liner for Mac OS X to fetch all of the files for app with your.app.id from your device and save them to (in this case) ~/Desktop/your.app.id:

(
    id=your.app.id &&
    dest=~/Desktop &&
    adb shell "run-as $id cp -r /data/data/$id /sdcard" &&
    adb -d pull "/sdcard/$id" "$dest" &&
    if [ -n "$id" ]; then adb shell "rm -rf /sdcard/$id"; fi
)

• Exclude the -d to pull from emulator
• Doesn't stomp your session variables
• You can paste the whole block into Terminal.app (or remove newlines if desired)

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

If the browser people see this as a security and/or usability problem, then the answer to your question is to simply not close the window, since by definition they will come up with solutions for your workaround anyway. There is a nice summation about the reasoning why the choice have been in the firefox bug database https://bugzilla.mozilla.org/show_bug.cgi?id=190515#c70

So what can you do?

Change the specification of your website, so that you have a solution for these people. You could for instance take it as an opportunity to direct them to a partner.

That is, see it as a handoff to someone else that (potentially) needs it. As an example, Hanselman had a recent article about what to do in the other similar situation, namely 404 errors: http://www.hanselman.com/blog/PutMissingKidsOnYour404PageEntirelyClientSideSolutionWithYQLJQueryAndMSAjax.aspx

I am working with an API with a lot of functions get as an input a char*.

I have created a small class to face this kind of problem, I have implemented the RAII idiom.

class DeepString
{
        DeepString(const DeepString& other);
        DeepString& operator=(const DeepString& other);
        char* internal_; 

    public:
        explicit DeepString( const string& toCopy): 
            internal_(new char[toCopy.size()+1]) 
        {
            strcpy(internal_,toCopy.c_str());
        }
        ~DeepString() { delete[] internal_; }
        char* str() const { return internal_; }
        const char* c_str()  const { return internal_; }
};

And you can use it as:

void aFunctionAPI(char* input);

//  other stuff

aFunctionAPI("Foo"); //this call is not safe. if the function modified the 
                     //literal string the program will crash
std::string myFoo("Foo");
aFunctionAPI(myFoo.c_str()); //this is not compiling
aFunctionAPI(const_cast<char*>(myFoo.c_str())); //this is not safe std::string 
                                                //implement reference counting and 
                                                //it may change the value of other
                                                //strings as well.
DeepString myDeepFoo(myFoo);
aFunctionAPI(myFoo.str()); //this is fine

I have called the class DeepString because it is creating a deep and unique copy (the DeepString is not copyable) of an existing string.

You should overwrite the properties using your own css. like so:

div.tooltip-inner {
    text-align: center;
    -webkit-border-radius: 0px;
    -moz-border-radius: 0px;
    border-radius: 0px;
    margin-bottom: 6px;
    background-color: #505050;
    font-size: 14px;
}

the selector choose the div that the tooltip is held (tooltip is added in by javascript and it usually does not belong to any container.

I found the SimpleLogger from heiswayi on GitHub good.

Little late but, can create a reusable javascript function for this purpose:

// Arguments: number to round, number of decimal places
function roundNumber(rnum, rlength) { 
    var newnumber = Math.round(rnum * Math.pow(10, rlength)) / Math.pow(10, rlength);
    return newnumber;
}

Call the function as

alert(roundNumber(192.168,2));

Maybe you can try this: though please note - This pulls the column count, not the row count

 using (SqlDataReader reader = command.ExecuteReader())
 {
     while (reader.Read())
     {
         int count = reader.VisibleFieldCount;
         Console.WriteLine(count);
     }
 }

After looking for so many answers on StackOverflow, I haven't seen an answer to fit my needs.

That is, to make top command to keep refreshing with given keyword, and we don't have to CTRL+C / top again and again when new processes spawn.

Thus I make a new one...

Here goes the no-restart-needed version.

__keyword=name_of_process; (while :; do __arg=$(pgrep -d',' -f $__keyword); if [ -z "$__arg" ]; then top -u 65536 -n 1; else top -c -n 1 -p $__arg; fi; sleep 1; done;)

Modify the __keyword and it should works. (Ubuntu 2.6.38 tested)

2.14.2015 added: The system workload part is missing with the code above. For people who cares about the "load average" part:

__keyword=name_of_process; (while :; do __arg=$(pgrep -d',' -f $__keyword); if [ -z "$__arg" ]; then top -u 65536 -n 1; else top -c -n 1 -p $__arg; fi; uptime; sleep 1; done;)

I figured it out. I had an error in my cloud formation template that was creating the EC2 instances. As a result, the EC2 instances that were trying to access the above code deploy buckets, were in different regions (not us-west-2). It seems like the access policies on the buckets (owned by Amazon) only allow access from the region they belong in. When I fixed the error in my template (it was wrong parameter map), the error disappeared

Remove the Newtonsoft.Json assembly from the project reference and add it again. You probably deleted or replaced the dll by accident.

The logic in the "one-liner" works fine. From personal experience, what has helped me is to assign the statements to variables (in their "True" form) and then use logical operators for the result:

A = year % 4 == 0
B = year % 100 == 0
C = year % 400 == 0

I used '==' in the B statement instead of "!=" and applied 'not' logical operator in the calculation:

leap = A and (not B or C)

This comes in handy with a larger set of conditions, and to simplify the boolean operation where applicable before writing a whole bunch of if statements.

Android Studio 1.3

1. Open Module Settings
2. Click on your module under Modules menu
3. In the properties tab, set the Source Compatibility and Target Compatibility to your java version.

I did nothing else and it worked for me.

   func init() -> ClassA {
    struct Static {
        static var onceToken : dispatch_once_t = 0
        static var instance : ClassA? = nil
    }

    dispatch_once(&Static.onceToken) {
        Static.instance = ClassA()
    }

    return Static.instance!
}

Yes, you can change the encoding of a specific file (or see what it has) with this Encoding Support plugin. With this plugin you will be able to handle the different encodings of your files without problems.

Now it is in version 1.4.0 for NetBeans 8.2 and I use it in Windows 10 several time ago.

The operation is very simple, in the status line you can see the encoding of the open file, and from there you can define its new encoding.

After "return" statement, you can't write any code(excluding try-finally block). Move your new activity codes before the "return" statements.

1. Add a local loop network in your normal PC (search google how to)
2. Click start -> type "ncpa.cpl" hit enter to open network connections.
3. While pressing Ctrl key, select both your wireless and recently created local loop network. right click on it and create the bridge.
4. Now in virtual network editor in vmware, select the network with type "Bridged" and change Bridged to option to the recently created bridge.

You will then have access to network via wifi card.

int lastInt = integerList[integerList.Count-1];

In addition to @thoughtrepo's answer:

Until we do not have definitely typed events in React it might be useful to have a special target interface for input controls:

export interface FormControlEventTarget extends EventTarget{
    value: string;
}

And then in your code cast to this type where is appropriate to have IntelliSense support:

 import {FormControlEventTarget} from "your.helper.library"

 (event.target as FormControlEventTarget).value;

Maybe it's possible to debug PHP on Visual Studio, but it's simpler and more logical to use Eclipse PDT or Netbeans IDE for your PHP projects, aside from Visual Studio if you need to use both technologies from two different vendors.

Yes there is:

std::vector<int> vec(SIZE, 0);

Use a vector instead of a dynamically allocated array. Benefits include not having to bother with explicitely deleting the array (it is deleted when the vector goes out of scope) and also that the memory is automatically deleted even if there is an exception thrown.

Edit: To avoid further drive-by downvotes from people that do not bother to read the comments below, I should make it more clear that this answer does not say that vector is always the right answer. But it sure is a more C++ way than "manually" making sure to delete an array.

Now with C++11, there is also std::array that models a constant size array (vs vector that is able to grow). There is also std::unique_ptr that manages a dynamically allocated array (that can be combined with initialization as answered in other answers to this question). Any of those are a more C++ way than manually handling the pointer to the array, IMHO.

Instead of

mount -o rw,remount /system/

use

mount -o rw,remount /system

mind the '/' at the end of the command. you ask why this matters? /system/ is the directory under /system while /system is the volume name.

Try this query:

SELECT cast(column_name as type) as col_identifier FROM tableName WHERE 1=1

Before comparing, the cast function will convert varchar type value to integer type.

Install this package:

pip3 install py_essentials

And use this code:

from py_essentials import simpleRandom as sr
print(sr.randomString(4))

More informations about the method other parameters are available here.

I use this, because it's very easy:

if [ `LANG=C type example 2>/dev/null|wc -l` = 1 ];then echo exists;else echo "not exists";fi

or

if [ `LANG=C type example 2>/dev/null|wc -l` = 1 ];then
echo exists
else echo "not exists"
fi

It uses shell builtins and programs' echo status to standard output and nothing to standard error. On the other hand, if a command is not found, it echos status only to standard error.

I use this one for work. leave off the []'s though in the @TEXT field, seems to want to return everything...

SET NOCOUNT ON

SELECT @TEXT as 'Search String'
DECLARE #databases CURSOR FOR SELECT NAME FROM master..sysdatabases where dbid>4
    DECLARE @c_dbname varchar(64)   
    OPEN #databases
    FETCH #databases INTO @c_dbname   
    WHILE @@FETCH_STATUS  -1
    BEGIN
        SELECT @SQL = 'INSERT INTO #results '
        SELECT @SQL = @SQL + 'SELECT ''' + @c_dbname + ''' AS db, o.name,o.xtype,m.definition '   
        SELECT @SQL = @SQL + ' FROM '+@c_dbname+'.sys.sql_modules m '   
        SELECT @SQL = @SQL + ' INNER JOIN '+@c_dbname+'..sysobjects o ON m.object_id=o.id'   
        SELECT @SQL = @SQL + ' WHERE [definition] LIKE ''%'+@TEXT+'%'''   
        EXEC(@SQL)
        FETCH #databases INTO @c_dbname
    END
    CLOSE #databases
DEALLOCATE #databases

SELECT * FROM #results order by db, xtype, objectname
DROP TABLE #results

if (capital.touched && capital != undefined && capital.length < 1 ) { 
//capital does exists
}

I have solved a similar problem by first importing the text into an excel spreadsheet, then using the Substitute function to replace both the single and double quotes as required by SQL Server, eg. SUBSTITUTE(SUBSTITUTE(A1, "'", "''"), """", "\""")

In my case, I had many rows (each a line of data to be cleaned then inserted) and had the spreadsheet automatically generate insert queries for the text once the substitution had been done eg. ="INSERT INTO [dbo].[tablename] ([textcolumn]) VALUES ('" & SUBSTITUTE(SUBSTITUTE(A1, "'", "''"), """", "\""") & "')"

I hope that helps.

Your code is passing a function as an argument to find. That function takes an element argument (of type Conversation) and returns void (meaning there is no return value). TypeScript describes this as (element: Conversation) => void'

What TypeScript is saying is that the find function doesn't expect to receive a function that takes a Conversation and returns void. It expects a function that takes a Conversations, a number and a Conversation array, and that this function should return a boolean.

So bottom line is that you either need to change your code to pass in the values to find correctly, or else you need to provide an overload to the definition of find in your definition file that accepts a Conversation and returns void.

Python 2.5.2 (r252:60911, Sep 27 2008, 07:03:14)
[GCC 4.3.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.

But really, you should use sys.stdout.write directly.

I like a single line open and close:

if [ ]; then ##
    ...
    ...
fi; ##

The '##' helps me easily find the start and end to the block comment. I can stick a number after the '##' if I've got a bunch of them. To turn off the comment, I just stick a '1' in the '[ ]'. I also avoid some issues I've had with single-quotes in the commented block.

Your second example does not work because there is no operator + for two string literals. Note that a string literal is not of type string, but instead is of type const char *. Your second example will work if you revise it like this:

const string message = string("Hello") + ",world" + exclam;

Thanks @Clint for the great answer:

Just wanted to highlight how easy it was to solve this using the Expando Object:

    var dynamicObject = new ExpandoObject() as IDictionary<string, Object>;
    foreach (var property in properties) {
        dynamicObject.Add(property.Key,property.Value);
    }

set height: 100%; and overflow:auto; for div inside .cell

With Ubuntu and C++ I had problems with the Character/Integer cast. I needed to use cv::waitKey()%256 to obtain the correct ASCII value.

Precision of a number is the number of digits.

Scale of a number is the number of digits after the decimal point.

What is generally implied when setting precision and scale on field definition is that they represent maximum values.

Example, a decimal field defined with precision=5 and scale=2 would allow the following values:

• 123.45 (p=5,s=2)
• 12.34 (p=4,s=2)
• 12345 (p=5,s=0)
• 123.4 (p=4,s=1)
• 0 (p=0,s=0)

The following values are not allowed or would cause a data loss:

• 12.345 (p=5,s=3) => could be truncated into 12.35 (p=4,s=2)
• 1234.56 (p=6,s=2) => could be truncated into 1234.6 (p=5,s=1)
• 123.456 (p=6,s=3) => could be truncated into 123.46 (p=5,s=2)
• 123450 (p=6,s=0) => out of range

Note that the range is generally defined by the precision: |value| < 10^p ...

For a pure CSS solution, scroll after the 2nd <hr>. The first one is the initial answer (given back in 2016)

The major flaw of the solutions above is they have a fixed height for the footer.
And that just doesn't cut it in the real world, where people use a zillion number of devices and have this bad habit of rotating them when you least expect it and **Poof!** there goes your page content behind the footer!

In the real world, you need a function that calculates the height of the footer and dynamically adjusts the page content's padding-bottom to accommodate that height. And you need to run this tiny function on page load and resize events as well as on footer's DOMSubtreeModified (just in case your footer gets dynamically updated asynchronously or it contains animated elements that change size when interacted with).

Here's a proof of concept, using jQuery v3.0.0 and Bootstrap v4-alpha, but there is no reason why it shouldn't work on lower versions of each.

<footer>I am a footer with dynamic content._x000D_
  <hr />_x000D_
</footer>

Initially, I have posted this solution here but I realized it might help more people if posted under this question.

Note: I have purposefully wrapped the $([selector]).accomodateFooter() as a jQuery plugin, so it could be run on any DOM element, as in most layouts it is not the $('body')'s bottom-padding that needs adjusting, but some page wrapper element with position:relative (usually the immediate parent of the footer).

Later edit (3+ years after initial answer):

At this point I no longer consider acceptable using JavaScript for positioning a dynamic content footer at the bottom of the page. It can be achieved with CSS alone, using flexbox, lightning fast, cross-browser.

Here it is:

// Left this in so you could inject content into the footer and test it:_x000D_
// (but it's no longer sizing the footer)_x000D_
_x000D_
function addMoreContentToFooter() {_x000D_
  var f = $('footer');_x000D_
  f.append($('<p />', {_x000D_
      text: "Human give me attention meow flop over sun bathe licks your face wake up wander around the house making large amounts of noise jump on top of your human's bed and fall asleep again.

If you generate an application with a template you are going to have something like this on the Startup class:

public void ConfigureServices(IServiceCollection services)
{
    // Add framework services.
    services.AddApplicationInsightsTelemetry(Configuration);

    services.AddMvc();
}

You can then add dependencies there, for example:

services.AddTransient<ITestService, TestService>();

If you want to access ITestService on your controller you can add IServiceProvider on the constructor and it will be injected:

public HomeController(IServiceProvider serviceProvider)

Then you can resolve the service you added:

var service = serviceProvider.GetService<ITestService>();

Note that to use the generic version you have to include the namespace with the extensions:

using Microsoft.Extensions.DependencyInjection;

ITestService.cs

public interface ITestService
{
    int GenerateRandom();
}

TestService.cs

public class TestService : ITestService
{
    public int GenerateRandom()
    {
        return 4;
    }
}

Startup.cs (ConfigureServices)

public void ConfigureServices(IServiceCollection services)
{
    services.AddApplicationInsightsTelemetry(Configuration);
    services.AddMvc();

    services.AddTransient<ITestService, TestService>();
}

HomeController.cs

using Microsoft.Extensions.DependencyInjection;

namespace Core.Controllers
{
    public class HomeController : Controller
    {
        public HomeController(IServiceProvider serviceProvider)
        {
            var service = serviceProvider.GetService<ITestService>();
            int rnd = service.GenerateRandom();
        }

I would also like to mention a new functionality of AngularJS ng-repeat, namely, special repeat start and end points. That functionality was added in order to repeat a series of HTML elements instead of just a single parent HTML element.

In order to use repeater start and end points you have to define them by using ng-repeat-start and ng-repeat-end directives respectively.

The ng-repeat-start directive works very similar to ng-repeat directive. The difference is that is will repeat all the HTML elements (including the tag it's defined on) up to the ending HTML tag where ng-repeat-end is placed (including the tag with ng-repeat-end).

Sample code (from a controller):

// ...
$scope.users = {};
$scope.users["182982"] = {name:"John", age: 30};
$scope.users["198784"] = {name:"Antonio", age: 32};
$scope.users["119827"] = {name:"Stephan", age: 18};
// ...

Sample HTML template:

<div ng-repeat-start="(id, user) in users">
    ==== User details ====
</div>
<div>
    <span>{{$index+1}}. </span>
    <strong>{{id}} </strong>
    <span class="name">{{user.name}} </span>
    <span class="age">({{user.age}})</span>
</div>

<div ng-if="!$first">
   <img src="/some_image.jpg" alt="some img" title="some img" />
</div>
<div ng-repeat-end>
    ======================
</div>

Output would look similar to the following (depending on HTML styling):

==== User details ====
1.  119827 Stephan (18)
======================
==== User details ====
2.  182982 John (30)
[sample image goes here]
======================
==== User details ====
3.  198784 Antonio (32)
[sample image goes here]
======================

As you can see, ng-repeat-start repeats all HTML elements (including the element with ng-repeat-start). All ng-repeat special properties (in this case $first and $index) also work as expected.

The last suggestion is the correct solution. Just to repeat, first set android:focusable="true" in the layout xml file, then requestFocus() on the view in your code.

I fixed it by deleting the hidden .svn folder and replaced it with the fresh checkout .svn and it worked. Probably this hidden folder got messed up!

Alternatively the same can be reached using form_tag with the syntax:

form_tag({controller: "people", action: "search"}, method: "get", class: "nifty_form")
# => '<form accept-charset="UTF-8" action="/people/search" method="get" class="nifty_form">'

As described in http://guides.rubyonrails.org/form_helpers.html#multiple-hashes-in-form-helper-calls

This is how I do it with Factory / Services and simple dependency injection (DI).

myApp = angular.module('myApp', [])

# PeopleService holds the "data".
angular.module('myApp').factory 'PeopleService', ()->
  [
    {name: "Jack"}
  ]

# Controller where PeopleService is injected
angular.module('myApp').controller 'PersonFormCtrl', ['$scope','PeopleService', ($scope, PeopleService)->
  $scope.people = PeopleService
  $scope.person = {} 

  $scope.add = (person)->
    # Simply push some data to service
    PeopleService.push angular.copy(person)
]

# ... and again consume it in another controller somewhere...
angular.module('myApp').controller 'PeopleListCtrl', ['$scope','PeopleService', ($scope, PeopleService)->
  $scope.people = PeopleService
]

Would like to add:

After update, such as

ALTER TABLE table_name modify column_name tinyint(4) NOT NULL;

If you get

ERROR 1138 (22004): Invalid use of NULL value

Make sure you update the table first to have values in the related column (so it's not null)

Results to text only allows a maximum of 8192 characters.

I use this approach

DECLARE @Query NVARCHAR(max);

set @Query = REPLICATE('A',4000)
set @Query = @Query + REPLICATE('B',4000)
set @Query = @Query + REPLICATE('C',4000)
set @Query = @Query + REPLICATE('D',4000)

select LEN(@Query)

SELECT @Query /*Won't contain any "D"s*/
SELECT @Query as [processing-instruction(x)] FOR XML PATH /*Not truncated*/

If you only want form elements that have a name attribute, you can filter the form elements.

const form = document.querySelector("your-form")
Array.from(form.elements).filter(e => e.getAttribute("name"))

You can either Drop the columns you do not need OR Select the ones you need

# Using DataFrame.drop
df.drop(df.columns[[1, 2]], axis=1, inplace=True)

# drop by Name
df1 = df1.drop(['B', 'C'], axis=1)

# Select the ones you want
df1 = df[['a','d']]

>>> the_list =[ ['a','b'], ['a','c'], ['b','d'] ]
>>> "b" in zip(*the_list)[1]
True

zip() takes a bunch of lists and groups elements together by index, effectively transposing the list-of-lists matrix. The asterisk takes the contents of the_list and sends it to zip as arguments, so you're effectively passing the three lists separately, which is what zip wants. All that remains is to check if "b" (or whatever) is in the list made up of elements with the index you're interested in.

You can explicitly enable escaping of Xml entities by using an attribute escapeXml value equals to true. FYI, it's by default "true".

Not clear where My_ConnectionString is coming from in your example, but try this

System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString

like this

Dim DBConnection As New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString)

My suggested name for this technique (including multiple top-level classes in a single source file) would be "mess". Seriously, I don't think it's a good idea - I'd use a nested type in this situation instead. Then it's still easy to predict which source file it's in. I don't believe there's an official term for this approach though.

As for whether this actually changes between implementations - I highly doubt it, but if you avoid doing it in the first place, you'll never need to care :)

Don't you try it with that program? It'll goto finally block and executing the finally block, but, the exception won't be handled. But, that exception can be overruled in the finally block!

Try setting the "endOfLine":"auto" in your .prettierrc file (inside the object)

Or set

"prettier/prettier": ["error", {
     ..
    "endOfLine":"auto"
     ..
  }],

inside the rules object of the eslintrc file.

If you are using windows machine endOfLine can be "crlf" basing on your git config.

myList.Count is a method on the list object, it just returns the value of a field so is very fast. As it is a small method it is very likely to be inlined by the compiler (or runtime), they may then allow other optimization to be done by the compiler.

myList.Count() is calling an extension method (introduced by LINQ) that loops over all the items in an IEnumerable, so should be a lot slower.

However (In the Microsoft implementation) the Count extension method has a “special case” for Lists that allows it to use the list’s Count property, this means the Count() method is only a little slower than the Count property.

It is unlikely you will be able to tell the difference in speed in most applications.

So if you know you are dealing with a List use the Count property, otherwise if you have a "unknown" IEnumerabl, use the Count() method and let it optimise for you.

Use Element.classList

document.getElementById('hello').classList.add('someClass');

The .add method will only add the class if it doesn't already exist on the element. So no need to worry about duplicate class names.

Create a new template and check DBname. Use that template for your tracefile.

Here's an example that finds div elements whose className contains atag:

//div[contains(@class, 'atag')]

Here's an example that finds div elements whose className contains atag and btag:

//div[contains(@class, 'atag') and contains(@class ,'btag')]

However, it will also find partial matches like class="catag bobtag".

If you don't want partial matches, see bobince's answer below.

This work for me in Angular 9:

  import {GoogleMap, GoogleMapsModule} from "@angular/google-maps";
  @ViewChild('Map') Map: GoogleMap; /* Element Map */

  locations = [
   { lat: 7.423568, lng: 80.462287 },
   { lat: 7.532321, lng: 81.021187 },
   { lat: 6.117010, lng: 80.126269 }
  ];

  constructor() {
   var bounds = new google.maps.LatLngBounds();
    setTimeout(() => {
     for (let u in this.locations) {
      var marker = new google.maps.Marker({
       position: new google.maps.LatLng(this.locations[u].lat, 
       this.locations[u].lng),
      });
      bounds.extend(marker.getPosition());
     }

     this.Map.fitBounds(bounds)
    }, 200)
  }

And it automatically centers the map according to the indicated positions.

Result:

Assuming one has a simple setup (CentOS 7, Apache 2.4.x, and PHP 5.6.20) and only one website (not assuming virtual hosting) ...

In the PHP sense, $_SERVER['SERVER_NAME'] is an element PHP registers in the $_SERVER superglobal based on your Apache configuration (**ServerName** directive with UseCanonicalName On ) in httpd.conf (be it from an included virtual host configuration file, whatever, etc ...). HTTP_HOST is derived from the HTTP host header. Treat this as user input. Filter and validate before using.

Here is an example of where I use $_SERVER['SERVER_NAME'] as the basis for a comparison. The following method is from a concrete child class I made named ServerValidator (child of Validator). ServerValidator checks six or seven elements in $_SERVER before using them.

In determining if the HTTP request is POST, I use this method.

public function isPOST()
{
    return (($this->requestMethod === 'POST')    &&  // Ignore
            $this->hasTokenTimeLeft()            &&  // Ignore
            $this->hasSameGETandPOSTIdentities() &&  // Ingore
            ($this->httpHost === filter_input(INPUT_SERVER, 'SERVER_NAME')));
}

By the time this method is called, all filtering and validating of relevant $_SERVER elements would have occurred (and relevant properties set).

The line ...

($this->httpHost === filter_input(INPUT_SERVER, 'SERVER_NAME')

... checks that the $_SERVER['HTTP_HOST'] value (ultimately derived from the requested host HTTP header) matches $_SERVER['SERVER_NAME'].

Now, I am using superglobal speak to explain my example, but that is just because some people are unfamiliar with INPUT_GET, INPUT_POST, and INPUT_SERVER in regards to filter_input_array().

The bottom line is, I do not handle POST requests on my server unless all four conditions are met. Hence, in terms of POST requests, failure to provide an HTTP host header (presence tested for earlier) spells doom for strict HTTP 1.0 browsers. Moreover, the requested host must match the value for ServerName in the httpd.conf, and, by extention, the value for $_SERVER('SERVER_NAME') in the $_SERVER superglobal. Again, I would be using INPUT_SERVER with the PHP filter functions, but you catch my drift.

Keep in mind that Apache frequently uses ServerName in standard redirects (such as leaving the trailing slash off a URL: Example, http://www.example.com becoming http://www.example.com/), even if you are not using URL rewriting.

I use $_SERVER['SERVER_NAME'] as the standard, not $_SERVER['HTTP_HOST']. There is a lot of back and forth on this issue. $_SERVER['HTTP_HOST'] could be empty, so this should not be the basis for creating code conventions such as my public method above. But, just because both may be set does not guarantee they will be equal. Testing is the best way to know for sure (bearing in mind Apache version and PHP version).

This should work perfect just copy this div code

<div onclick="thevid=document.getElementById('thevideo'); thevid.style.display='block'; this.style.display='none'">
<img style="cursor: pointer;" alt="" src="http://oi59.tinypic.com/33trpyo.jpg" />
</div>
<div id="thevideo" style="display: none;">
<embed width="631" height="466" type="application/x-shockwave-flash" src="https://www.youtube.com/v/26EpwxkU5js?version=3&amp;hl=en_US&amp;autoplay=1" allowFullScreen="true" allowscriptaccess="always" allowfullscreen="true" />
</div>

It should be that the particular mvn command execs and does not return, thereby not executing the rest of the commands.

Check JavaScript Cookies on W3Schools.com for setting and getting cookie values via JS.

Just use the setCookie and getCookie methods mentioned there.

So, the code will look something like:

<script>
function setCookie(c_name, value, exdays) {
    var exdate = new Date();
    exdate.setDate(exdate.getDate() + exdays);
    var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
    document.cookie = c_name + "=" + c_value;
}

function getCookie(c_name) {
    var i, x, y, ARRcookies = document.cookie.split(";");
    for (i = 0; i < ARRcookies.length; i++) {
        x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
        y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
        x = x.replace(/^\s+|\s+$/g, "");
        if (x == c_name) {
            return unescape(y);
        }
    }
}

function cssSelected() {
    var cssSelected = $('#myList')[0].value;
    if (cssSelected !== "select") {
        setCookie("selectedCSS", cssSelected, 3);
    }
}

$(document).ready(function() {
    $('#myList')[0].value = getCookie("selectedCSS");
})
</script>
<select id="myList" onchange="cssSelected();">
    <option value="select">--Select--</option>
    <option value="style-1.css">CSS1</option>
    <option value="style-2.css">CSS2</option>
    <option value="style-3.css">CSS3</option>
    <option value="style-4.css">CSS4</option>
</select>

If you're using a wrapper layer (like Kitchen CI) and you're running a 32b host, you'll have to preempt the installation of Vagrant boxes. Their default provider is the opscode "family" of binaries.

So before kitchen create default-ubuntu-1204 make sure you use:

vagrant box add default-ubuntu-1204 http://opscode-vm-bento.s3.amazonaws.com/vagrant/virtualbox/opscode_ubuntu-12.04-i386_chef-provisionerless.box

for using the 32b image if your host doesn't support word size virtualization

The simplest way that doesn't require third party libraries it to create a URL object and then call either openConnection or openStream on it. Note that this is a pretty basic API, so you won't have a lot of control over the headers.

Yes, here's an example:

CREATE TABLE myTable ( col1 int, createdDate datetime DEFAULT(getdate()), updatedDate datetime DEFAULT(getdate()) )

You can INSERT into the table without indicating the createdDate and updatedDate columns:

INSERT INTO myTable (col1) VALUES (1)

Or use the keyword DEFAULT:

INSERT INTO myTable (col1, createdDate, updatedDate) VALUES (1, DEFAULT, DEFAULT)

Then create a trigger for updating the updatedDate column:

CREATE TRIGGER dbo.updateMyTable 
ON dbo.myTable
FOR UPDATE 
AS 
BEGIN 
    IF NOT UPDATE(updatedDate) 
        UPDATE dbo.myTable SET updatedDate=GETDATE() 
        WHERE col1 IN (SELECT col1 FROM inserted) 
END 
GO

Easy Way:

function diff_hours(dt2, dt1) 
 {

  var diff =(dt2.getTime() - dt1.getTime()) / 1000;
  diff /= (60 * 60);
  return Math.abs(Math.round(diff));

 }


function diff_minutes(dt2, dt1)

To make function to wait for list to be fetched.

getArrayOfData() {
    return DataModel.find({}).then(function (storedDataArray) {
        return storedDataArray;
    }).catch(function(err){
        if (err) {
            throw new Error(err.message);
        }
    });
}

I agree with Paul Tomblin. I usually use the keyset's iterator, and then base my condition off the value for that key:

Iterator<Integer> it = map.keySet().iterator();
while(it.hasNext()) {
    Integer key = it.next();
    Object val = map.get(key);
    if (val.shouldBeRemoved()) {
        it.remove();
    }
}

Actually, it feels like swift is trying to promote strings to be treated less like objects and more like values. However this doesn't mean under the hood swift doesn't treat strings as objects, as am sure you all noticed that you can still invoke methods on strings and use their properties.

For example:-

//example of calling method (String to Int conversion)
let intValue = ("12".toInt())
println("This is a intValue now \(intValue)")


//example of using properties (fetching uppercase value of string)
let caUpperValue = "ca".uppercaseString
println("This is the uppercase of ca \(caUpperValue)")

In objectC you could pass the reference to a string object through a variable, on top of calling methods on it, which pretty much establishes the fact that strings are pure objects.

Here is the catch when you try to look at String as objects, in swift you cannot pass a string object by reference through a variable. Swift will always pass a brand new copy of the string. Hence, strings are more commonly known as value types in swift. In fact, two string literals will not be identical (===). They are treated as two different copies.

let curious = ("ca" === "ca")
println("This will be false.. and the answer is..\(curious)")

As you can see we are starting to break aways from the conventional way of thinking of strings as objects and treating them more like values. Hence .isEqualToString which was treated as an identity operator for string objects is no more a valid as you can never get two identical string objects in Swift. You can only compare its value, or in other words check for equality(==).

 let NotSoCuriousAnyMore = ("ca" == "ca")
 println("This will be true.. and the answer is..\(NotSoCuriousAnyMore)")

This gets more interesting when you look at the mutability of string objects in swift. But thats for another question, another day. Something you should probably look into, cause its really interesting. :) Hope that clears up some confusion. Cheers!

I am using a .Net Core 2.1 Web Application and could not get a single answer here to work. I either got a blank parameter (if the method was called at all) or a 500 server error. I started playing with every possible combination of answers and finally got a working result.

In my case the solution was as follows:

Script - stringify the original array (without using a named property)

    $.ajax({
        type: 'POST',
        contentType: 'application/json; charset=utf-8',
        url: mycontrolleraction,
        data: JSON.stringify(things)
    });

And in the controller method, use [FromBody]

    [HttpPost]
    public IActionResult NewBranch([FromBody]IEnumerable<Thing> things)
    {
        return Ok();
    }

Failures include:

• Naming the content

  data: { content: nodes }, // Server error 500

• Not having the contentType = Server error 500

Notes

• dataType is not needed, despite what some answers say, as that is used for the response decoding (so not relevant to the request examples here).
• List<Thing> also works in the controller method

For me, nothing from this list of answers worked.

What finally did the trick is:

1. Performing an uninstall of VS by running the installer with the /uninstall /force command-line options (ref. https://msdn.microsoft.com/en-us/library/mt720585.aspx)
2. Manually renaming all VS14 and nuget related folders from the following places:
   • %AppData%/Local and its sub-folders
   • %AppData%/Roaming and its sub-folders
   • %ProgramData% and its sub-folders
   • %ProgramFiles% and its sub-folders
   • %ProgramFiles(x86)% and its sub-folders
   • %ProgramData%/Package Cache itself
3. Rebooting the machine
4. Installing again.

Try it this way in a simple manner it will work

$userset = User::where('name',$data['name'])->first();
if(!$userset) echo "no user found";

I had the same issue with Windows 10.

First, I installed graphviz-2.38.0 with the following command without any problem...

install -c anaconda graphviz=2.38.0

Second, I installed pydotplus with the following command without any problem...

install -c conda-forge pydotplus

After that, when I got to my step to visualize my decision tree had the following issue with {InvocationException: GraphViz's executables not found}...

C:\Users\admin\Anaconda3\lib\site-packages\pydotplus\graphviz.py in create(self, prog, format)
   1958             if self.progs is None:
   1959                 raise InvocationException(
-> 1960                     'GraphViz\'s executables not found')
   1961 
   1962         if prog not in self.progs:

InvocationException: GraphViz's executables not found

In my case, all I had to do to fix it is to put the environment path of the graphviz executables in my user PATH environment variable and this fixed it. Just make sure it is the path where YOUR.exe files are located :)

C:\Users\admin\Anaconda3\pkgs\graphviz-2.38.0-4\Library\bin\graphviz

As said before, VBA does not support Multithreading.

But you don't need to use C# or vbScript to start other VBA worker threads.

I use VBA to create VBA worker threads.

First copy the makro workbook for every thread you want to start.

Then you can start new Excel Instances (running in another Thread) simply by creating an instance of Excel.Application (to avoid errors i have to set the new application to visible).

To actually run some task in another thread i can then start a makro in the other application with parameters form the master workbook.

To return to the master workbook thread without waiting i simply use Application.OnTime in the worker thread (where i need it).

As semaphore i simply use a collection that is shared with all threads. For callbacks pass the master workbook to the worker thread. There the runMakroInOtherInstance Function can be reused to start a callback.

'Create new thread and return reference to workbook of worker thread
Public Function openNewInstance(ByVal fileName As String, Optional ByVal openVisible As Boolean = True) As Workbook
    Dim newApp As New Excel.Application
    ThisWorkbook.SaveCopyAs ThisWorkbook.Path & "\" & fileName
    If openVisible Then newApp.Visible = True
    Set openNewInstance = newApp.Workbooks.Open(ThisWorkbook.Path & "\" & fileName, False, False) 
End Function

'Start macro in other instance and wait for return (OnTime used in target macro)
Public Sub runMakroInOtherInstance(ByRef otherWkb As Workbook, ByVal strMakro As String, ParamArray var() As Variant)
    Dim makroName As String
    makroName = "'" & otherWkb.Name & "'!" & strMakro
    Select Case UBound(var)
        Case -1:
            otherWkb.Application.Run makroName
        Case 0:
            otherWkb.Application.Run makroName, var(0)
        Case 1:
            otherWkb.Application.Run makroName, var(0), var(1)
        Case 2:
            otherWkb.Application.Run makroName, var(0), var(1), var(2)
        Case 3:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3)
        Case 4:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3), var(4)
        Case 5:
            otherWkb.Application.Run makroName, var(0), var(1), var(2), var(3), var(4), var(5)
    End Select
End Sub

Public Sub SYNCH_OR_WAIT()
    On Error Resume Next
    While masterBlocked.Count > 0
        DoEvents
    Wend
    masterBlocked.Add "BLOCKED", ThisWorkbook.FullName
End Sub

Public Sub SYNCH_RELEASE()
    On Error Resume Next
    masterBlocked.Remove ThisWorkbook.FullName
End Sub

Sub runTaskParallel()
    ...
    Dim controllerWkb As Workbook
    Set controllerWkb = openNewInstance("controller.xlsm")

    runMakroInOtherInstance controllerWkb, "CONTROLLER_LIST_FILES", ThisWorkbook, rootFold, masterBlocked
    ...
End Sub

wll it looks like I found the answer, although I havent tested it yet

var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
saveAs(blob, "hello world.txt");

You're getting that error because the default value current_time is not valid for the type DATETIME. That's what it says, and that's whats going on.

The only field you can use current_time on is a timestamp.

Try adding the appropriate root certificate

This is always going to be a much safer option than just blindly accepting unauthorised end points, which should in turn only be used as a last resort.

This can be as simple as adding

require('https').globalAgent.options.ca = require('ssl-root-cas/latest').create();

to your application.

The SSL Root CAs npm package (as used here) is a very useful package regarding this problem.

The simplest make file can be

all : test

test : test.o
        gcc -o test test.o 

test.o : test.c
        gcc -c test.c

clean :
        rm test *.o

"If you get this, the app has installed on your device. You have to tap the icon. It will ask you if you really want to run it. Say “yes” and then Build & Run again."

To add to that, this only holds true the moment you get the error, if you click OK, then tap on the app. It will do nothing. Scratched my head on that for 30 odd minutes, searching for alternative ways to address the problem.

Ctrl+Shift+F will format a file in Eclipse, breaking long lines into multiple lines and nicely word-wrapping comments. You can also highlight just a section of text and format that.

I realize this is not an automatic soft/hard word wrap like the other answers, but I don't think the question was asking for anything fancy.
