Anything in the public folder is accessible at the root path (/) so change your img tag to read:

<img src="/images/rss.jpg" alt="rss feed" />

If you wanted to use a rails tag, use this:

<%= image_tag("rss.jpg", :alt => "rss feed") %>

Split the text into lines, and draw each separately:

function fillTextMultiLine(ctx, text, x, y) {
  var lineHeight = ctx.measureText("M").width * 1.2;
  var lines = text.split("\n");
  for (var i = 0; i < lines.length; ++i) {
    ctx.fillText(lines[i], x, y);
    y += lineHeight;
  }
}

EDIT : this answer used to claim that it isn't possible to center an absolutely positioned element with margin: auto;, but this simply isn't true. Because this is the most up-voted and accepted answer, I guessed I'd just change it to be correct.

When you apply the following CSS to an element

position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin: auto;

And then give the element a fixed width and height, such as 200px or 40%, the element will center itself.

Here's a Fiddle that demonstrates the effect.

I too had the same problem and resolved.

As per the above-mentioned solutions by others, I tried all the things and it does not solve my problem.

Even if you have two SDK locations, no need to worry about it and check whether your android home is set to Android studio SDK (If you have the Android repository and everything in that SDK location).

Solution:

• Go to Your project structure
• Select your modules
• Click the dependance tap on the right side
• Add library dependency
• "com.google.android.gms:play-service:+"

I hope it will solve your problem.

Yes there is. With .NET 3.5:

int sum = arr.Sum();
Console.WriteLine(sum);

If you're not using .NET 3.5 you could do this:

int sum = 0;
Array.ForEach(arr, delegate(int i) { sum += i; });
Console.WriteLine(sum);

Some 2+ years after I asked this question I'd like to explain it the way I'd want it explained back when I was still a complete newb and would be most beneficial to people who want to understand the process.

First of all, forget the "11111111" example value, which is not really all that suited for the visual explanation of the process. So let the initial value be 10111011 (187 decimal) which will be a little more illustrative of the process.

1 - how to read a 3 bit value starting from the second bit:

    ___  <- those 3 bits
10111011 

The value is 101, or 5 in decimal, there are 2 possible ways to get it:

• mask and shift

In this approach, the needed bits are first masked with the value 00001110 (14 decimal) after which it is shifted in place:

    ___
10111011 AND
00001110 =
00001010 >> 1 =
     ___
00000101

The expression for this would be: (value & 14) >> 1

• shift and mask

This approach is similar, but the order of operations is reversed, meaning the original value is shifted and then masked with 00000111 (7) to only leave the last 3 bits:

    ___
10111011 >> 1
     ___
01011101 AND
00000111
00000101

The expression for this would be: (value >> 1) & 7

Both approaches involve the same amount of complexity, and therefore will not differ in performance.

2 - how to write a 3 bit value starting from the second bit:

In this case, the initial value is known, and when this is the case in code, you may be able to come up with a way to set the known value to another known value which uses less operations, but in reality this is rarely the case, most of the time the code will know neither the initial value, nor the one which is to be written.

This means that in order for the new value to be successfully "spliced" into byte, the target bits must be set to zero, after which the shifted value is "spliced" in place, which is the first step:

    ___ 
10111011 AND
11110001 (241) =
10110001 (masked original value)

The second step is to shift the value we want to write in the 3 bits, say we want to change that from 101 (5) to 110 (6)

     ___
00000110 << 1 =
    ___
00001100 (shifted "splice" value)

The third and final step is to splice the masked original value with the shifted "splice" value:

10110001 OR
00001100 =
    ___
10111101

The expression for the whole process would be: (value & 241) | (6 << 1)

Bonus - how to generate the read and write masks:

Naturally, using a binary to decimal converter is far from elegant, especially in the case of 32 and 64 bit containers - decimal values get crazy big. It is possible to easily generate the masks with expressions, which the compiler can efficiently resolve during compilation:

• read mask for "mask and shift": ((1 << fieldLength) - 1) << (fieldIndex - 1), assuming that the index at the first bit is 1 (not zero)
• read mask for "shift and mask": (1 << fieldLength) - 1 (index does not play a role here since it is always shifted to the first bit
• write mask : just invert the "mask and shift" mask expression with the ~ operator

How does it work (with the 3bit field beginning at the second bit from the examples above)?

00000001 << 3
00001000  - 1
00000111 << 1
00001110  ~ (read mask)
11110001    (write mask)

The same examples apply to wider integers and arbitrary bit width and position of the fields, with the shift and mask values varying accordingly.

Also note that the examples assume unsigned integer, which is what you want to use in order to use integers as portable bit-field alternative (regular bit-fields are in no way guaranteed by the standard to be portable), both left and right shift insert a padding 0, which is not the case with right shifting a signed integer.

Even easier:

Using this set of macros (but only in C++ since it relies on the generation of member functions):

#define GETMASK(index, size) ((((size_t)1 << (size)) - 1) << (index))
#define READFROM(data, index, size) (((data) & GETMASK((index), (size))) >> (index))
#define WRITETO(data, index, size, value) ((data) = (((data) & (~GETMASK((index), (size)))) | (((value) << (index)) & (GETMASK((index), (size))))))
#define FIELD(data, name, index, size) \
  inline decltype(data) name() const { return READFROM(data, index, size); } \
  inline void set_##name(decltype(data) value) { WRITETO(data, index, size, value); }

You could go for something as simple as:

struct A {
  uint bitData;
  FIELD(bitData, one, 0, 1)
  FIELD(bitData, two, 1, 2)
};

And have the bit fields implemented as properties you can easily access:

A a;
a.set_two(3);
cout << a.two();

Replace decltype with gcc's typeof pre-C++11.

You can add other repo first as a remote to your current repo:

git remote add other_name PATH_TO_OTHER_REPO

then fetch brach from that remote:

git fetch other_name branch_name:branch_name

this creates that branch as a new branch in your current repo, then you can diff that branch with any of your branches, for example, to compare current branch against new branch(branch_name):

git diff branch_name

Try this. Basically, connection could fail if your system doesn't trust nuget certificate.

gradlew is a wrapper(w - character) that uses gradle.

Under the hood gradlew performs three main things:

• Download and install the correct gradle version
• Parse the arguments
• Call a gradle task

Using Gradle Wrapper we can distribute/share a project to everybody to use the same version and Gradle's functionality(compile, build, install...) even if it has not been installed.

To create a wrapper run:

gradle wrapper

This command generate:

gradle-wrapper.properties will contain the information about the Gradle distribution

*./ Is used on Unix to specify the current directory

Use CONVERT with the Value specifier of 101, whilst casting your data to date:

CONVERT(VARCHAR(10), CAST(Created_TS AS DATE), 101)

This answer support the @ macrocosme suggestion.

I am using heat map as hist2d plot. Additionally I use cmin=0.5 for no count value and cmap for color, r represent the reverse of given color.

Describe statistics.

# np.arange(data.min(), data.max()+binwidth, binwidth)
bin_x = np.arange(0.6, 7 + 0.3, 0.3)
bin_y = np.arange(12, 58 + 3, 3)
plt.hist2d(data=fuel_econ, x='displ', y='comb', cmin=0.5, cmap='viridis_r', bins=[bin_x, bin_y]);
plt.xlabel('Dispalcement (1)');
plt.ylabel('Combine fuel efficiency (mpg)');

plt.colorbar();

If you have more as one Project in your Project Map use THE SAME hard coded PathFile PDB Name in all your Sub-Projects:

Use e.g.

D:\Visual Studio Projects\my_app\MyFile.pdb

Dont use e.g.

$(IntDir)\MyFile.pdb

in all the Sub-Projects !!!

= Compiler Param /Fd

why not simply

public Date(){
    data = new int[]{0,0,0};
}

the reason you got the error is because int[] data = ... declares a new variable and hides the field data

however it should be noted that the contents of the array are already initialized to 0 (the default value of int)

npm link pain:

-Module name gulp-task

-Project name project-x

You want to link gulp-task:

1: Go to the gulp-task directory then do npm link this will symlink the project to your global modules

2: Go to your project project-x then do npm install make sure to remove the current node_modules directory

Now you want to remove this madness and use the real gulp-task, we have two options:

Option 1: Unlink via npm:

1: Go to your project and do npm unlink gulp-task this will remove the linked installed module

2: Go to the gulp-task directory and do npm unlink to remove symlink. Notice we didn't use the name of the module

3: celebrate

What if this didn't work, verify by locating your global installed module. My are location ls -la /usr/local/lib/node_modules/ if you are using nvm it will be a different path

Option 2: Remove the symlink like a normal linux guru

1: locate your global dependencies cd /usr/local/lib/node_modules/

2: removing symlink is simply using the rm command

rm gulp-task make sure you don't have / at the end

rm gulp-task/ is wrong

rm gulp-task ??

try this

$("#inp").focus(function(){$("#sel").attr('disabled','true');});

$("#inp").blur(function(){$("#sel").removeAttr('disabled');});

vice versa for the select also.

Did you read clang documentation ? You're probably looking for -emit-llvm.

For people like me, linq addicts, and based on svick's answer, here a linq approach:

using System.Linq;
//...
//make it linq iterable. 
var obj_linq = Response.Cast<KeyValuePair<string, JToken>>();

Now you can make linq expressions like:

JToken x = obj_linq
          .Where( d => d.Key == "my_key")
          .Select(v => v)
          .FirstOrDefault()
          .Value;
string y = ((JValue)x).Value;

Or just:

var y = obj_linq
       .Where(d => d.Key == "my_key")
       .Select(v => ((JValue)v.Value).Value)
       .FirstOrDefault();

Or this one to iterate over all data:

obj_linq.ToList().ForEach( x => { do stuff } ); 

In windows first check under services if world wide web publishing services is running. If not start it.

If you cannot find it switch on IIS features of windows: In 7,8,10 it is under control panel , "turn windows features on or off". Internet Information Services World Wide web services and Internet information Services Hostable Core are required. Not sure if there is another way to get it going on windows, but this worked for me for all browsers. You might need to add localhost or http:/127.0.0.1 to the trusted websites also under IE settings.

Try c.ToString("F6");

In JavaScript, the type of key/value store you are attempting to use is an object literal, rather than an array. You are mistakenly creating a composite array object, which happens to have other properties based on the key names you provided, but the array portion contains no elements.

Instead, declare valueToPush as an object and push that onto cookie_value_add:

// Create valueToPush as an object {} rather than an array []
var valueToPush = {};

// Add the properties to your object
// Note, you could also use the valueToPush["productID"] syntax you had
// above, but this is a more object-like syntax
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;

cookie_value_add.push(valueToPush);

// View the structure of cookie_value_add
console.dir(cookie_value_add);

Use \r instead of \n.

Substituting by \n inserts a null character into the text. To get a newline, use \r. When searching for a newline, you’d still use \n, however. This asymmetry is due to the fact that \n and \r do slightly different things:

\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input CR). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it). xxd shows a hexdump of the resulting file.

echo bar > test
(echo 'Before:'; xxd test) > output.txt
vim test '+s/b/\n/' '+s/a/\r/' +wq
(echo 'After:'; xxd test) >> output.txt
more output.txt

Before:
0000000: 6261 720a                                bar.
After:
0000000: 000a 720a                                ..r.

In other words, \n has inserted the byte 0x00 into the text; \r has inserted the byte 0x0a.

It is so simple, you have 2 objects with the same name and when you say: bank_holiday[month] python thinks you wanna run your function and got ERROR.

Just rename your array to bank_holidays <--- add a 's' at the end! like this:

bank_holidays= [1, 0, 1, 1, 2, 0, 0, 1, 0, 0, 0, 2] #gives the list of bank holidays in each month

def bank_holiday(month):
   if month <1 or month > 12:
       print("Error: Out of range")
       return
   print(bank_holidays[month-1],"holiday(s) in this month ")

bank_holiday(int(input("Which month would you like to check out: ")))

The official ports (TCP:5222 and TCP:5269) are listed in RFC 6120. Contrary to the claims of a previous answer, XEP-0174 does not specify a port. Thus TCP:5298 might be customary for Link-Local XMPP, but is not official.

You can use other ports than the reserved ones, though: You can make your DNS SRV record point to any machine and port you like.

File transfers (XEP-0234) are these days handled using Jingle (XEP-0166). The same goes for RTP sessions (XEP-0167). They do not specify ports, though, since Jingle negotiates the creation of the data stream between the XMPP clients, but the actual data is then transferred by other means (e.g. RTP) through that stream (i.e. not usually through the XMPP server, even though in-band transfers are possible). Beware that Jingle is comprised of several XEPs, so make sure to have a look at the whole list of XMPP extensions.

EDIT: I haven't tried this, so I can't vouch for it! And you already know you shouldn't be doing this, so please don't do it. BUT...

Try looking here: http://sqlblog.com/blogs/denis_gobo/archive/2008/05/08/6703.aspx

The key bit is this bit which I have attempted to tweak for your purposes:

DECLARE @SQL varchar(500)

SELECT @SQL = 'osql -S' +@@servername +' -E -q "exec dbName..sprocName "'

EXEC master..xp_cmdshell @SQL

This is what myself and tekromancr came up with.

Example element:

<a href="http://www.google.com" id="btn" type="button" class="btn btn-disabled" data-placement="top" data-toggle="tooltip" data-title="I'm a tooltip">Press Me</a>

note: the tooltip attributes can be added to a separate div, in which the id of that div is to be used when calling .tooltip('destroy'); or .tooltip();

this enables the tooltip, put it in any javascript that is included in the html file. this line might not be necessary to add, however. (if the tooltip shows w/o this line then don't bother including it)

$("#element_id").tooltip();

destroys tooltip, see below for usage.

$("#element_id").tooltip('destroy');

prevents the button from being clickable. because the disabled attribute is not being used, this is necessary, otherwise the button would still be clickable even though it "looks" as if it is disabled.

$("#element_id").click(
  function(evt){
    if ($(this).hasClass("btn-disabled")) {
      evt.preventDefault();
      return false;
    }
  });

Using bootstrap, the classes btn and btn-disabled are available to you. Override these in your own .css file. you can add any colors or whatever you want the button to look like when disabled. Make sure you keep the cursor: default; you can also change what .btn.btn-success looks like.

.btn.btn-disabled{
    cursor: default;
}

add the code below to whatever javascript is controlling the button becoming enabled.

$("#element_id").removeClass('btn-disabled');
$("#element_id").addClass('btn-success');
$('#element_id).tooltip('destroy');

tooltip should now only show when the button is disabled.

if you are using angularjs i also have a solution for that, if desired.

Try:

 DateTime.TryParseExact(txtStartDate.Text, formats, 
        System.Globalization.CultureInfo.InvariantCulture,
        System.Globalization.DateTimeStyles.None, out startDate)

Cool!! I need a bit of code like this but for comparing directory paths on Linux machines. I found that this wasn't working in situations where a parent directory was the target.

Here is a directory friendly version of the method:

 public static String getRelativePath(String targetPath, String basePath, 
     String pathSeparator) {

 boolean isDir = false;
 {
   File f = new File(targetPath);
   isDir = f.isDirectory();
 }
 //  We need the -1 argument to split to make sure we get a trailing 
 //  "" token if the base ends in the path separator and is therefore
 //  a directory. We require directory paths to end in the path
 //  separator -- otherwise they are indistinguishable from files.
 String[] base = basePath.split(Pattern.quote(pathSeparator), -1);
 String[] target = targetPath.split(Pattern.quote(pathSeparator), 0);

 //  First get all the common elements. Store them as a string,
 //  and also count how many of them there are. 
 String common = "";
 int commonIndex = 0;
 for (int i = 0; i < target.length && i < base.length; i++) {
     if (target[i].equals(base[i])) {
         common += target[i] + pathSeparator;
         commonIndex++;
     }
     else break;
 }

 if (commonIndex == 0)
 {
     //  Whoops -- not even a single common path element. This most
     //  likely indicates differing drive letters, like C: and D:. 
     //  These paths cannot be relativized. Return the target path.
     return targetPath;
     //  This should never happen when all absolute paths
     //  begin with / as in *nix. 
 }

 String relative = "";
 if (base.length == commonIndex) {
     //  Comment this out if you prefer that a relative path not start with ./
     relative = "." + pathSeparator;
 }
 else {
     int numDirsUp = base.length - commonIndex - (isDir?0:1); /* only subtract 1 if it  is a file. */
     //  The number of directories we have to backtrack is the length of 
     //  the base path MINUS the number of common path elements, minus
     //  one because the last element in the path isn't a directory.
     for (int i = 1; i <= (numDirsUp); i++) {
         relative += ".." + pathSeparator;
     }
 }
 //if we are comparing directories then we 
 if (targetPath.length() > common.length()) {
  //it's OK, it isn't a directory
  relative += targetPath.substring(common.length());
 }

 return relative;
}

Here are the possible ways to take a unique pointer as an argument, as well as their associated meaning.

(A) By Value

Base(std::unique_ptr<Base> n)
  : next(std::move(n)) {}

In order for the user to call this, they must do one of the following:

Base newBase(std::move(nextBase));
Base fromTemp(std::unique_ptr<Base>(new Base(...));

To take a unique pointer by value means that you are transferring ownership of the pointer to the function/object/etc in question. After newBase is constructed, nextBase is guaranteed to be empty. You don't own the object, and you don't even have a pointer to it anymore. It's gone.

This is ensured because we take the parameter by value. std::move doesn't actually move anything; it's just a fancy cast. std::move(nextBase) returns a Base&& that is an r-value reference to nextBase. That's all it does.

Because Base::Base(std::unique_ptr<Base> n) takes its argument by value rather than by r-value reference, C++ will automatically construct a temporary for us. It creates a std::unique_ptr<Base> from the Base&& that we gave the function via std::move(nextBase). It is the construction of this temporary that actually moves the value from nextBase into the function argument n.

(B) By non-const l-value reference

Base(std::unique_ptr<Base> &n)
  : next(std::move(n)) {}

This has to be called on an actual l-value (a named variable). It cannot be called with a temporary like this:

Base newBase(std::unique_ptr<Base>(new Base)); //Illegal in this case.

The meaning of this is the same as the meaning of any other use of non-const references: the function may or may not claim ownership of the pointer. Given this code:

Base newBase(nextBase);

There is no guarantee that nextBase is empty. It may be empty; it may not. It really depends on what Base::Base(std::unique_ptr<Base> &n) wants to do. Because of that, it's not very evident just from the function signature what's going to happen; you have to read the implementation (or associated documentation).

Because of that, I wouldn't suggest this as an interface.

(C) By const l-value reference

Base(std::unique_ptr<Base> const &n);

I don't show an implementation, because you cannot move from a const&. By passing a const&, you are saying that the function can access the Base via the pointer, but it cannot store it anywhere. It cannot claim ownership of it.

This can be useful. Not necessarily for your specific case, but it's always good to be able to hand someone a pointer and know that they cannot (without breaking rules of C++, like no casting away const) claim ownership of it. They can't store it. They can pass it to others, but those others have to abide by the same rules.

(D) By r-value reference

Base(std::unique_ptr<Base> &&n)
  : next(std::move(n)) {}

This is more or less identical to the "by non-const l-value reference" case. The differences are two things.

1. You can pass a temporary:

   Base newBase(std::unique_ptr<Base>(new Base)); //legal now..
   

2. You must use std::move when passing non-temporary arguments.

The latter is really the problem. If you see this line:

Base newBase(std::move(nextBase));

You have a reasonable expectation that, after this line completes, nextBase should be empty. It should have been moved from. After all, you have that std::move sitting there, telling you that movement has occurred.

The problem is that it hasn't. It is not guaranteed to have been moved from. It may have been moved from, but you will only know by looking at the source code. You cannot tell just from the function signature.

Recommendations

• (A) By Value: If you mean for a function to claim ownership of a unique_ptr, take it by value.
• (C) By const l-value reference: If you mean for a function to simply use the unique_ptr for the duration of that function's execution, take it by const&. Alternatively, pass a & or const& to the actual type pointed to, rather than using a unique_ptr.
• (D) By r-value reference: If a function may or may not claim ownership (depending on internal code paths), then take it by &&. But I strongly advise against doing this whenever possible.

How to manipulate unique_ptr

You cannot copy a unique_ptr. You can only move it. The proper way to do this is with the std::move standard library function.

If you take a unique_ptr by value, you can move from it freely. But movement doesn't actually happen because of std::move. Take the following statement:

std::unique_ptr<Base> newPtr(std::move(oldPtr));

This is really two statements:

std::unique_ptr<Base> &&temporary = std::move(oldPtr);
std::unique_ptr<Base> newPtr(temporary);

(note: The above code does not technically compile, since non-temporary r-value references are not actually r-values. It is here for demo purposes only).

The temporary is just an r-value reference to oldPtr. It is in the constructor of newPtr where the movement happens. unique_ptr's move constructor (a constructor that takes a && to itself) is what does the actual movement.

If you have a unique_ptr value and you want to store it somewhere, you must use std::move to do the storage.

From my Hello World contest, Which one is Laravel? I think you can guess. I used docker container for the test and here is the results

To make http-response "Hello World":

• Golang with log handler stdout : 6000 rps
• SpringBoot with Log Handler stdout: 3600 rps
• Laravel 5 with off log :230 rps

Here's an elegant one-liner solution that uses stack algorithm, though one may take some time to understand the beauty of this implementation.

const getSum = arr => (arr.length === 1) ? arr[0] : arr.pop() + getSum(arr);

getSum([1, 2, 3, 4, 5]) //15

Basically, the function accepts an array and checks whether the array contains exactly one item. If false, it pop the last item out of the stack and return the updated array.

The beauty of this snippet is that the function includes arr[0] checking to prevent infinite looping. Once it reaches the last item, it returns the entire sum.

It's a difference in focus. Emulators¹ focus on recreating the behavior of a system, with no regard for how the system functions internally. Simulators² focus on modeling the components of a system. You use an emulator when you care mostly about what a system does, and a simulator when you care about how it does it.

As for their general English meanings, emulation is "the endeavor to equal or to excel another in qualities or actions", while simulation is "to model, replicate, duplicate the behavior, appearance or properties of". Not much difference. Emulation comes from æmulus, "striving, rivaling," and is related to "imitate" and "image," which suggests a surface-lever resemblance. "Simulation" comes from similis "like", as does the word "similar," which perhaps suggests a deeper congruence.

There are many paths through your code whereby your variables are not initialized, which is why the compiler complains.

Specifically, you are not validating the user input for creditPlan - if the user enters a value of anything else than "0","1","2" or "3", then none of the branches indicated will be executed (and creditPlan will not be defaulted to zero as per your user prompt).

As others have mentioned, the compiler error can be avoided by either a default initialization of all derived variables before the branches are checked, OR ensuring that at least one of the branches is executed (viz, mutual exclusivity of the branches, with a fall through else statement).

I would however like to point out other potential improvements:

• Validate user input before you trust it for use in your code.
• Model the parameters as a whole - there are several properties and calculations applicable to each plan.
• Use more appropriate types for data. e.g. CreditPlan appears to have a finite domain and is better suited to an enumeration or Dictionary than a string. Financial data and percentages should always be modelled as decimal, not double to avoid rounding issues, and 'status' appears to be a boolean.
• DRY up repetitive code. The calculation, monthlyCharge = balance * annualRate * (1/12)) is common to more than one branch. For maintenance reasons, do not duplicate this code.
• Possibly more advanced, but note that Functions are now first class citizens of C#, so you can assign a function or lambda as a property, field or parameter!.

e.g. here is an alternative representation of your model:

    // Keep all Credit Plan parameters together in a model
    public class CreditPlan
    {
        public Func<decimal, decimal, decimal> MonthlyCharge { get; set; }
        public decimal AnnualRate { get; set; }
        public Func<bool, Decimal> LateFee { get; set; }
    }

    // DRY up repeated calculations
    static private decimal StandardMonthlyCharge(decimal balance, decimal annualRate)
    { 
       return balance * annualRate / 12;
    }

    public static Dictionary<int, CreditPlan> CreditPlans = new Dictionary<int, CreditPlan>
    {
        { 0, new CreditPlan
            {
                AnnualRate = .35M, 
                LateFee = _ => 0.0M, 
                MonthlyCharge = StandardMonthlyCharge
            }
        },
        { 1, new CreditPlan
            {
                AnnualRate = .30M, 
                LateFee = late => late ? 0 : 25.0M,
                MonthlyCharge = StandardMonthlyCharge
            }
        },
        { 2, new CreditPlan
            {
                AnnualRate = .20M, 
                LateFee = late => late ? 0 : 35.0M,
                MonthlyCharge = (balance, annualRate) => balance > 100 
                    ? balance * annualRate / 12
                    : 0
            }
        },
        { 3, new CreditPlan
            {
                AnnualRate = .15M, 
                LateFee = _ => 0.0M,
                MonthlyCharge = (balance, annualRate) => balance > 500 
                    ? (balance - 500) * annualRate / 12
                    : 0
            }
        }
    };

In addition to @Connor Leech's answer.

If you want to create a new custom typography type of your own, define the following in your css file.

.text-foo {
  .text-emphasis-variant(#FFFFFF);
}

The mixin text-emphasis-variant is defined in Bootstrap's mixins.less file.

IF EXISTS
      (SELECT * 
      FROM schema.sys.objects
      WHERE name = 'func_name')
    DROP FUNCTION [dbo].[func_name]

You can access the timezone by the following script:

SELECT * FROM pg_timezone_names WHERE name = current_setting('TIMEZONE');

• current_setting('TIMEZONE') will give you Continent / Capital information of settings
• pg_timezone_names The view pg_timezone_names provides a list of time zone names that are recognized by SET TIMEZONE, along with their associated abbreviations, UTC offsets, and daylight-savings status.
• name column in a view (pg_timezone_names) is time zone name.

output will be :

name- Europe/Berlin, 
abbrev - CET, 
utc_offset- 01:00:00, 
is_dst- false

Normally, JavaScript does not follow strict rules, hence increasing chances of errors. After using "use strict", the JavaScript code should follow strict set of rules as in other programming languages such as use of terminators, declaration before initialization, etc.

If "use strict" is used, the code should be written by following a strict set of rules, hence decreasing the chances of errors and ambiguities.

You can read it by chunks (byte buffer[] = new byte[2048]) and write the chunks to a ByteArrayOutputStream. From the ByteArrayOutputStream you can retrieve the contents as a byte[], without needing to determine its size beforehand.

Check this, Where first two parameters are input parameters and 3rd one is Output parameter in Procedure definition.

DECLARE @PK_Code INT;
EXEC USP_Validate_Login  'ID', 'PWD', @PK_Code OUTPUT
SELECT @PK_Code

You hide Bootstrap modals with:

$('#modal').modal('hide');

Saying $().hide() makes the matched element invisible, but as far as the modal-related code is concerned, it's still there. See the Methods section in the Modals documentation.

I would use isset and empty:

session_start();
if(isset($_SESSION['blah']) && !empty($_SESSION['blah'])) {
   echo 'Set and not empty, and no undefined index error!';
}

array_key_exists is a nice alternative to using isset to check for keys:

session_start();
if(array_key_exists('blah',$_SESSION) && !empty($_SESSION['blah'])) {
    echo 'Set and not empty, and no undefined index error!';
}

Make sure you're calling session_start before reading from or writing to the session array.

Before we try to solve the invalid character problem, the lack of curly braces around the if and else if statements is wreaking havoc on your program's logic. Change it to this:

if (personPlay.equals(computerPlay)) {
   System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
   if (computerPlay.equals("S")) 
      System.out.println("Rock crushes scissors. You win!!");
   else if (computerPlay.equals("P")) 
        System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
   if (computerPlay.equals("S")) 
       System.out.println("Scissor cuts paper. You lose!!"); 
   else if (computerPlay.equals("R")) 
        System.out.println("Paper eats rock. You win!!");
} 
else if (personPlay.equals("S")) {
     if (computerPlay.equals("P")) 
         System.out.println("Scissor cuts paper. You win!!"); 
     else if (computerPlay.equals("R")) 
        System.out.println("Rock breaks scissors. You lose!!");
}
else 
     System.out.println("Invalid user input.");

Much clearer! It's now actually a piece of cake to catch the bad characters. You need to move the else statement to somewhere that will catch the errors before you attempt to process anything else. So change everything to:

if( /* insert your check for bad characters here */ ) { 
     System.out.println("Invalid user input.");
}
else if (personPlay.equals(computerPlay)) {
   System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
   if (computerPlay.equals("S")) 
      System.out.println("Rock crushes scissors. You win!!");
   else if (computerPlay.equals("P")) 
        System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
   if (computerPlay.equals("S")) 
       System.out.println("Scissor cuts paper. You lose!!"); 
   else if (computerPlay.equals("R")) 
        System.out.println("Paper eats rock. You win!!");
} 
else if (personPlay.equals("S")) {
     if (computerPlay.equals("P")) 
         System.out.println("Scissor cuts paper. You win!!"); 
     else if (computerPlay.equals("R")) 
        System.out.println("Rock breaks scissors. You lose!!");
}

After one of my fixes for managed application I had the same thing, like how to verify that my application will not have the same memory leak after my next change, so I've wrote something like Object Release Verification framework, please take a look on the NuGet package ObjectReleaseVerification. You can find a sample here https://github.com/outcoldman/OutcoldSolutions-ObjectReleaseVerification-Sample, and information about this sample http://outcoldman.ru/en/blog/show/322

Firstly run this query

SHOW VARIABLES LIKE '%char%';

You have character_set_server='latin1'

for eg if CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci replace it to CHARSET=latin1 and remove the collate

You are good to go

I created my own module, StyleMe. I made it so I can do much with little typing. Example:

var StyleMe = require('styleme');
StyleMe.extend() // extend the string prototype

console.log("gre{Hello} blu{world}!".styleMe()) // Logs hello world! with 'hello' being green, and 'world' being blue with '!' being normal.

It can also be nested:

console.log("This is normal red{this is red blu{this is blue} back to red}".styleMe())

Or, if you dont want to extend the string prototype, you can just any of the 3 other options:

console.log(styleme.red("a string"))
console.log("Hello, this is yellow text".yellow().end())
console.log(styleme.style("some text","red,bbl"))

We can compare data from two tables of DB2 tables using the below simple query,

Step 1:- Select which all columns we need to compare from table (T1) of schema(S)

     SELECT T1.col1,T1.col3,T1.col5 from S.T1

Step 2:- Use 'Minus' keyword for comparing 2 tables.

Step 3:- Select which all columns we need to compare from table (T2) of schema(S)

     SELECT T2.col1,T2.col3,T2.col5 from S.T1

END result:

     SELECT T1.col1,T1.col3,T1.col5 from S.T1
     MINUS 
     SELECT T2.col1,T2.col3,T2.col5 from S.T1;

If the query returns no rows then the data is exactly the same.

I wouldn't push regular code into an exception block. Just check whether any rows exist that meet your condition, and proceed from there:

declare
  any_rows_found number;
begin
  select count(*)
  into   any_rows_found
  from   my_table
  where  rownum = 1 and
         ... other conditions ...

  if any_rows_found = 1 then
    ...
  else
    ...
  end if;

There's a great link about sending a POST request here by Example Depot::

try {
    // Construct data
    String data = URLEncoder.encode("key1", "UTF-8") + "=" + URLEncoder.encode("value1", "UTF-8");
    data += "&" + URLEncoder.encode("key2", "UTF-8") + "=" + URLEncoder.encode("value2", "UTF-8");

    // Send data
    URL url = new URL("http://hostname:80/cgi");
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);
    OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
    wr.write(data);
    wr.flush();

    // Get the response
    BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String line;
    while ((line = rd.readLine()) != null) {
        // Process line...
    }
    wr.close();
    rd.close();
} catch (Exception e) {
}

If you want to send a GET request you can modify the code slightly to suit your needs. Specifically you have to add the parameters inside the constructor of the URL. Then, also comment out this wr.write(data);

One thing that's not written and you should beware of, is the timeouts. Especially if you want to use it in WebServices you have to set timeouts, otherwise the above code will wait indefinitely or for a very long time at least and it's something presumably you don't want.

Timeouts are set like this conn.setReadTimeout(2000); the input parameter is in milliseconds

Have a look at the example in this link :

http://docs.angularjs.org/api/ngSanitize.$sanitize

Basically, angular has a directive to insert html into pages. In your case you can insert the html using the ng-bind-html directive like so :

If you already have done all this :

// My magic HTML string function.
function htmlString (str) {
    return "<h1>" + str + "</h1>";
}

function Ctrl ($scope) {
  var str = "HELLO!";
  $scope.htmlString = htmlString(str);
}
Ctrl.$inject = ["$scope"];

Then in your html within the scope of that controller, you could

<div ng-bind-html="htmlString"></div>

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

Environment.GetCommandLineArgs()[0]

A very easy to use service is provided by ws.geonames.org. Here's an example URL:

http://ws.geonames.org/countryCode?lat=43.7534932&lng=28.5743187&type=JSON

And here's some (jQuery) code which I've added to your code:

if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
        $.getJSON('http://ws.geonames.org/countryCode', {
            lat: position.coords.latitude,
            lng: position.coords.longitude,
            type: 'JSON'
        }, function(result) {
            alert('Country: ' + result.countryName + '\n' + 'Code: ' + result.countryCode);
        });
    });
}?

Try it on jsfiddle.net ...

View -> Show Symbol -> uncheck Show All characters

Just make sure you don't have any dependencies on the current state in there.

I got the same error but when using tensorboard:

Fatal error in launcher: Unable to create process using '"'

I found out that the problem was caused by existing two copies of tensotboard.exe in two different directories and both directories were added to the path:

C:\Program Files\Python36\Scripts

and

C:\Users\...\AppData\Local\Programs\Python\Python36\Scripts

I removed the first one from the path and it fixed the problem.

If just want to use Linq, you can override Equals and GetHashCode methods.

Product class:

public class Product
{
    public string ProductName { get; set; }
    public int Id { get; set; }


    public override bool Equals(object obj)
    {
        if (!(obj is Product))
        {
            return false;
        }

        var other = (Product)obj;
        return Id == other.Id;
    }

    public override int GetHashCode()
    {
        return Id.GetHashCode();
    }
}

Main Method:

static void Main(string[] args)
    {

        var products = new List<Product>
        {
            new Product{ ProductName="Product 1",Id = 1},
            new Product{ ProductName="Product 2",Id = 2},
            new Product{ ProductName="Product 4",Id = 5},
            new Product{ ProductName="Product 3",Id = 3},
            new Product{ ProductName="Product 4",Id = 4},
            new Product{ ProductName="Product 6",Id = 4},
            new Product{ ProductName="Product 6",Id = 4},
        };

        var itemsDistinctByProductName = products.Distinct().ToList();

        foreach (var product in itemsDistinctByProductName)
        {
            Console.WriteLine($"Product Id : {product.Id} ProductName : {product.ProductName} ");
        }

        Console.ReadKey();
    }

Another way, using inline style and the spread operator

style={{
  ...completed ? { textDecoration: completed } : {}
}}

That way be useful in some situations where you want to add a bunch of properties at the same time base on the condition.

Try this - https://github.com/laracasts/PHP-Vars-To-Js-Transformer Is simple way to append PHP variables to Javascript.

Square brackets are meant for character class, and you're actually trying to match any one of: s, |, s (again), e, a, s (again), o and n.

Use parentheses instead for grouping:

(s|season)

or non-capturing group:

(?:s|season)

Note: Non-capture groups tell the engine that it doesn't need to store the match, while the other one (capturing group does). For small stuff, either works, for 'heavy duty' stuff, you might want to see first if you need the match or not. If you don't, better use the non-capture group to allocate more memory for calculation instead of storing something you will never need to use.

You need arguments like AF_UNIX or AF_INET to specify which type of socket addressing you would be using to implement IPC socket communication. AF stands for Address Family.

As in BSD standard Socket (adopted in Python socket module) addresses are represented as follows:

1. A single string is used for the AF_UNIX/AF_LOCAL address family. This option is used for IPC on local machines where no IP address is required.

2. A pair (host, port) is used for the AF_INET address family, where host is a string representing either a hostname in Internet domain notation like 'daring.cwi.nl' or an IPv4 address like '100.50.200.5', and port is an integer. Used to communicate between processes over the Internet.

AF_UNIX , AF_INET6 , AF_NETLINK , AF_TIPC , AF_CAN , AF_BLUETOOTH , AF_PACKET , AF_RDS are other option which could be used instead of AF_INET.

This thread about the differences between AF_INET and PF_INET might also be useful.

I managed to solve the problem by the following steps :
1. Disable windows updates(but check the option "let users install updates manually")
2. Reboot the PC
3. Manually install kb2999226 update from VS install folder (packages/Patch/x64/Windows6.1-KB299926-x64.msu)
4. Start the VS install
5. After install is finished turn back automatic updates

The application is a server which simply runs until the system shuts down or it receives a Ctrl+C or the console window is closed.

Due to the extraordinary nature of the application, it is not feasible to "gracefully" exit. (It may be that I could code another application which would send a "server shutdown" message but that would be overkill for one application and still insufficient for certain circumstances like when the server (Actual OS) is actually shutting down.)

Because of these circumstances I added a "ConsoleCtrlHandler" where I stop my threads and clean up my COM objects etc...

Public Declare Auto Function SetConsoleCtrlHandler Lib "kernel32.dll" (ByVal Handler As HandlerRoutine, ByVal Add As Boolean) As Boolean

Public Delegate Function HandlerRoutine(ByVal CtrlType As CtrlTypes) As Boolean

Public Enum CtrlTypes
  CTRL_C_EVENT = 0
  CTRL_BREAK_EVENT
  CTRL_CLOSE_EVENT
  CTRL_LOGOFF_EVENT = 5
  CTRL_SHUTDOWN_EVENT
End Enum

Public Function ControlHandler(ByVal ctrlType As CtrlTypes) As Boolean
.
.clean up code here
.
End Function

Public Sub Main()
.
.
.
SetConsoleCtrlHandler(New HandlerRoutine(AddressOf ControlHandler), True)
.
.
End Sub

This setup seems to work out perfectly. Here is a link to some C# code for the same thing.

this should work for your date format

order by convert(date, your_column, 104) desc

Here is another Linq approach which extracts the first number out of a string.

int result = 0;
bool success = int.TryParse(new string(input
                     .SkipWhile(x => !char.IsDigit(x))
                     .TakeWhile(x => char.IsDigit(x))
                     .ToArray()), out result);

Examples:

string input = "123 foo 456"; // 123
string input = "foo 456";     // 456
string input = "123 foo";     // 123

As the more recent MySQL documentation on view restrictions says:

Before MySQL 5.7.7, subqueries cannot be used in the FROM clause of a view.

This means, that choosing a MySQL v5.7.7 or newer or upgrading the existing MySQL instance to such a version, would remove this restriction on views completely.

However, if you have a current production MySQL version that is earlier than v5.7.7, then the removal of this restriction on views should only be one of the criteria being assessed while making a decision as to upgrade or not. Using the workaround techniques described in the other answers may be a more viable solution - at least on the shorter run.

See ?merge:

the name "row.names" or the number 0 specifies the row names.

Example:

R> de <- merge(d, e, by=0, all=TRUE)  # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0                 # replace NA values
R> de
  Row.names   a   b   c   d   e   f   g   h   i  j  k  l  m  n  o  p  q  r  s
1         1 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10 11 12 13 14 15 16 17 18 19

take look at this snippet from my project

 $("input[type="submit"]", "#letter-form").on("click",
        function(e) {
             e.preventDefault();


$.post($("#letter-form").attr('action'), $("#letter-form").serialize(),
                 function(response) {// your response from form submit
                    if (response.result === 'Redirect') {
                        window.location = response.url;
                    } else {
                        Message(response.saveChangesResult, response.operation, response.data);
                    }
});
$(this).attr('disabled', 'disabled'); //this is what you want

so just disabled the button after your operation executed

$(this).attr('disabled', 'disabled');

Try this:

MyContext Context = new MyContext(); 
Context.YourEntity.Add(obj);
Context.SaveChanges();
int ID = obj._ID;

Use localStorage to store the fact that you opened the page :

$(document).ready(function() {
    var yetVisited = localStorage['visited'];
    if (!yetVisited) {
        // open popup
        localStorage['visited'] = "yes";
    }
});

SELECT col1,
  col2
FROM
  (SELECT rownum X,col_table1 FROM table1) T1
INNER JOIN
  (SELECT rownum Y, col_table2 FROM table2) T2
ON T1.X=T2.Y;

You get that error because you haven't saved your file, save it for example "holamundo.py" then run it Ctrl + B

Update Since extract_numeric is deprecated, we can use parse_number from readr package.

library(readr)
parse_number(years)

Here is another option with extract_numeric

library(tidyr)
extract_numeric(years)
#[1] 20  1

For future visitors - use this for range: ($A$1:$A$10)

Example
=COUNTIF($G$6:$G$9;J6)>0

Really have to do this with JS. Here's a solution. I didn't use your class names, but I called the div within the td class name of "full-height" :-) Used jQuery, obviously. Note this was called from jQuery(document).ready(function(){ setFullHeights();}); Also note if you have images, you are going to have to iterate through them first with something like:

function loadedFullHeights(){
var imgCount = jQuery(".full-height").find("img").length;
if(imgCount===0){
    return setFullHeights();
}
var loaded = 0;
jQuery(".full-height").find("img").load(function(){
    loaded++;
    if(loaded ===imgCount){
        setFullHeights()
    }
});

}

And you would want to call the loadedFullHeights() from docReady instead. This is actually what I ended up using just in case. Got to think ahead you know!

function setFullHeights(){
var par;
var height;
var $ = jQuery;
var heights=[];
var i = 0;
$(".full-height").each(function(){
    par =$(this).parent();
    height = $(par).height();
    var tPad = Number($(par).css('padding-top').replace('px',''));
    var bPad = Number($(par).css('padding-bottom').replace('px',''));
    height -= tPad+bPad;
    heights[i]=height;
    i++;
});
for(ii in heights){
    $(".full-height").eq(ii).css('height', heights[ii]+'px');
}

}

use this

 double num;
    string candidate = "1";
    if (double.TryParse(candidate, out num))
    {
        // It's a number!


 }

 select convert_tz(now(),@@session.time_zone,'+05:30')

replace '+05:30' with desired timezone. see here - https://stackoverflow.com/a/3984412/2359994

to format into desired time format, eg:

 select DATE_FORMAT(convert_tz(now(),@@session.time_zone,'+05:30') ,'%b %d %Y %h:%i:%s %p') 

you will get similar to this -> Dec 17 2014 10:39:56 AM

UPDATE: This is only true if you use ONLYOFFICE instead of MS Excel.

There is actually a flow in all answers provided here and also in the accepted one. The flow is that whenever you have an empty cell in excel and copy that, in the clipboard you have 2 tab chars next to each other, so after splitting you get one additional item in array, which then appears as an extra cell in that row and moves all other cells by one. So to avoid that you basically need to replace all double tab (tabs next to each other only) chars in a string with one tab char and only then split it.

An updated version of @userfuser's jsfiddle is here to fix that issue by filtering pasted data with removeExtraTabs

http://jsfiddle.net/sTX7y/794/

function removeExtraTabs(string) {
  return string.replace(new RegExp("\t\t", 'g'), "\t");
}

function generateTable() {
  var data = removeExtraTabs($('#pastein').val());
  var rows = data.split("\n");
  var table = $('<table />');

  for (var y in rows) {
    var cells = rows[y].split("\t");
    var row = $('<tr />');
    for (var x in cells) {
      row.append('<td>' + cells[x] + '</td>');
    }
    table.append(row);
  }

  // Insert into DOM
  $('#excel_table').html(table);
}

$(document).ready(function() {
  $('#pastein').on('paste', function(event) {
    $('#pastein').on('input', function() {
      generateTable();
      $('#pastein').off('input');
    })
  })
})

Use o parameter of pgsql command.

-o, --output=FILENAME send query results to file (or |pipe)

psql -d DatabaseName -U UserName -c "SELECT * FROM TABLE" -o /root/Desktop/file.txt

One of the things to also keep in mind is that when you have Visual Studio 2010 SP1 installed some C++ compilers and libraries may have been removed. There's been an update made available by Microsoft to make sure those are brought back to your system.

Install this update to restore the Visual C++ compilers and libraries that may have been removed when Visual Studio 2010 Service Pack 1 (SP1) was installed. The compilers and libraries are part of the Microsoft Windows Software Development Kit for Windows 7 and the .NET Framework 4 (later referred to as the Windows SDK 7.1).

Also, when you read the VS2010 SP1 README you'll also notice that some notes have been made in regards to the Windows 7 SDK (See section 2.2.1) installation. It may be that one of these conditions may apply to you and therefore may need to uncheck the C++ compiler-checkbox as the SDK installer will attempt to install an older version of compilers ÓR you may need to uninstall VS2010 SP1 and re-run the SDK 7.1 installation, repair or modification.

Condition 1: If the Visual C++ Compilers checkbox is selected when the Windows SDK 7.1 is installed, repaired, or modified after Visual Studio 2010 SP1 has been installed, the error may be encountered and some selected components may not be installed.

Workaround: Clear the Visual C++ Compilers checkbox before you run the Windows SDK 7.1 installation, repair, or modification.

Condition 2: If the Visual C++ Compilers checkbox is selected when the Windows SDK 7.1 is installed, repaired, or modified after Visual Studio 2010 has been installed but Visual Studio 2010 SP1 has not been uninstalled, the error may be encountered.

Workaround: Uninstall Visual Studio 2010 SP1 and then rerun the Windows SDK 7.1 installation, repair, or modification.

However, even then I found that I still needed to uninstall any existing Visual C++ 2010 redistributables, as has been suggested by mgrandi.

To solve the issue, you are using the z-index on the footer and header, but you forgot about the position, if a z-index is to be used, the element must have a position:

Add to your footer and header this CSS:

position: relative; 

EDITED:

Also noticed that the background image on the #backstretch has a negative z-index, don't use that, some browsers get really weird...

Remove From the #backstretch:

z-index: -999999;

Read a little bit about Z-Index here!

I tried the marked solution here first. It worked but it is kind hacky, and you need to redo it every time you update the gcc. I finally find a better solution by doing the followings:

1. Project -> Properties -> C/C++ General -> Preprocessor Include Paths, Macros, etc.
2. Providers -> CDT GCC built-in compiler settings
3. Uncheck Use global provider shared between projects (you can also modify the global provider if it fits your need)
4. In Command to get compiler specs, add -std=c++11 at the end
5. Index->Rebuild

Voila, easy and simple. Hopefully this helps.

Note: I am on Kepler. I am not sure if this works on earlier Eclipse.

As an alternative for handling both cases addressed in Ali's excellent answer, I usually add

# With C++11 support
greaterThan(QT_MAJOR_VERSION, 4){    
CONFIG += c++11
} else {
QMAKE_CXXFLAGS += -std=c++0x
}

to my project files. This can be handy when you don't really care much about which Qt version is people using in your team, but you want them to have C++11 enabled in any case.

For anyone that's coming to this and none of the other solutions helped, in my case this manifested on a route that handled image uploading but didn't handle timeouts, and thus if the upload took too long and timed out, when the callback was fired after the timeout response had been sent, calling res.send() resulted in the crash as the headers were already set to account for the timeout.

This was easily reproduced by setting a very short timeout and hitting the route with a decently-large image, the crash was reproduced every time.

for UNIQUEIDENTIFIER datatype in sql server try this

Alter table table_name
add ID UNIQUEIDENTIFIER not null unique default(newid())

If you want to create primary key out of that column use this

ALTER TABLE table_name
ADD CONSTRAINT PK_name PRIMARY KEY (ID);

If you are building a serious pipeline with the Build Flow Plugin, you can pass parameters between jobs with the DSL like this :

Supposing an available string parameter "CVS_TAG", in order to pass it to other jobs :

build("pipeline_begin", CVS_TAG: params['CVS_TAG'])
parallel (
   // will be scheduled in parallel.
   { build("pipeline_static_analysis", CVS_TAG: params['CVS_TAG']) },
   { build("pipeline_nonreg", CVS_TAG: params['CVS_TAG']) }
)
// will be triggered after previous jobs complete
build("pipeline_end", CVS_TAG: params['CVS_TAG'])

Hint for displaying available variables / params :

// output values
out.println '------------------------------------'
out.println 'Triggered Parameters Map:'
out.println params
out.println '------------------------------------'
out.println 'Build Object Properties:'
build.properties.each { out.println "$it.key -> $it.value" }
out.println '------------------------------------'

CREATE TABLE new_table LIKE old_table;

or u can use this

CREATE TABLE new_table as SELECT * FROM old_table WHERE 1 GROUP BY [column to remove duplicates by];

Use PHP Document Object Model:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   $DOM = new DOMDocument;
   $DOM->loadHTML($str);

   //get all H1
   $items = $DOM->getElementsByTagName('h1');

   //display all H1 text
   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "<br/>";
?>

This outputs as:

 T1
 T2
 T3

[EDIT]: After OP Clarification:

If you want the content like Lorem ipsum. etc, you can directly use this regex:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   echo preg_replace("#<h1.*?>.*?</h1>#", "", $str);
?>

this outputs:

Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG

If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

+---------------------+
|   <<enumeration>>   |
|    DayOfTheWeek     |

| Monday              |
| Tuesday             |
| ...                 |
+---------------------+

Once it is defined, you can use it as the type of an Attribute just like you would a Datatype or the name one of your own Classes.

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.

Here's a picture of a slightly different example in ArgoUML:

Just to add to others, a note specific to forking.

It's good to realize that technically, cloning the repo and forking the repo are the same thing. Do:

git clone $some_other_repo

and you can tap yourself on the back---you have just forked some other repo.

Git, as a VCS, is in fact all about cloning forking. Apart from "just browsing" using remote UI such as cgit, there is very little to do with git repo that does not involve forking cloning the repo at some point.

However,

• when someone says I forked repo X, they mean that they have created a clone of the repo somewhere else with intention to expose it to others, for example to show some experiments, or to apply different access control mechanism (eg. to allow people without Github access but with company internal account to collaborate).

  Facts that: the repo is most probably created with other command than git clone, that it's most probably hosted somewhere on a server as opposed to somebody's laptop, and most probably has slightly different format (it's a "bare repo", ie. without working tree) are all just technical details.

  The fact that it will most probably contain different set of branches, tags or commits is most probably the reason why they did it in the first place.

  (What Github does when you click "fork", is just cloning with added sugar: it clones the repo for you, puts it under your account, records the "forked from" somewhere, adds remote named "upstream", and most importantly, plays the nice animation.)

• When someone says I cloned repo X, they mean that they have created a clone of the repo locally on their laptop or desktop with intention study it, play with it, contribute to it, or build something from source code in it.

The beauty of Git is that it makes this all perfectly fit together: all these repos share the common part of block commit chain so it's possible to safely (see note below) merge changes back and forth between all these repos as you see fit.

Note: "safely" as long as you don't rewrite the common part of the chain, and as long as the changes are not conflicting.

I have dealt WCF with large file (serveral GB) upload where store data in memory is not an option. My solution is to store message stream to a temp file and use seek to find out begin and end of binary data.

I tried opening php-cgi.exe directly and it gave me a more clear error message.

Another alternative:

head -$((${RANDOM} % `wc -l < file` + 1)) file | tail -1

Check if you actually have installed the buildVersionTools you are using. In my case I tried 25.0.1 whilst I only had 25.0.2.

To check it go to the SDK Manager, clicking the icon:

Then click Launch Standalone SDK Manager at the bottom:

Now check whatever you need and install packages.

Hope it helps!

Alternatives to the excellent sed answer by jfgagne, and which don't include the matching line :

• awk '/TERMINATE/ {y=1;next} y' ( https://stackoverflow.com/a/18166628 )
• awk '/TERMINATE/ ? c++ : c' ( https://stackoverflow.com/a/23984891 )
• perl -ne 'print unless 1 .. /TERMINATE/' ( https://stackoverflow.com/a/18167194 )

I made this work in this way:

<button class="btn" ng-click='toggleClass($event)'>button one</button>
<button class="btn" ng-click='toggleClass($event)'>button two</button>

in your controller:

$scope.toggleClass = function (event) {
    $(event.target).toggleClass('active');
}

There's no easy way to do it. This is kind of the point of hashing the password in the first place. :)

One thing you should be able to do is set a temporary password for them manually and send them that.

I hesitate to mention this because it's a bad idea (and it's not guaranteed to work anyway), but you could try looking up the hash in a rainbow table like milw0rm to see if you can recover the old password that way.

There is a simple way using Linq GroupBy Method.

var duplicateValues = dt.AsEnumerable() 

        .GroupBy(row => row[0]) 

        .Where(group => (group.Count() == 1 || group.Count() > 1)) 

        .Select(g => g.Key); 



foreach (var d in duplicateValues)

        Console.WriteLine(d);

In file config/database.php where :

'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',

Change this line to this :

'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',

Like tomash said before: There's no easy way.

You might want to take a look at my answer here.
It explains how to realize a sliding (dimension changing) view.
In this case it was a left and right view: Left expanding, right disappearing.
It's might not do exactly what you need but with inventive spirit you can make it work ;)

the @require meta does not work when you want to unbind events on a webpage using jQuery, you have to use a jQuery library included in the webpage and then get it in Greasemonkey with var $ = unsafeWindow.jQuery; How do I unbind jquery event handlers in greasemonkey?

You can use is_uploaded_file():

if(!file_exists($_FILES['myfile']['tmp_name']) || !is_uploaded_file($_FILES['myfile']['tmp_name'])) {
    echo 'No upload';
}

From the docs:

Returns TRUE if the file named by filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried to trick the script into working on files upon which it should not be working--for instance, /etc/passwd.

This sort of check is especially important if there is any chance that anything done with uploaded files could reveal their contents to the user, or even to other users on the same system.

EDIT: I'm using this in my FileUpload class, in case it helps:

public function fileUploaded()
{
    if(empty($_FILES)) {
        return false;       
    } 
    $this->file = $_FILES[$this->formField];
    if(!file_exists($this->file['tmp_name']) || !is_uploaded_file($this->file['tmp_name'])){
        $this->errors['FileNotExists'] = true;
        return false;
    }   
    return true;
}

To undo your last commit, simply do git reset --hard HEAD~.

Edit: this answer applied to an earlier version of the question that did not mention preserving local changes; the accepted answer from Tim is indeed the correct one. Thanks to qwertzguy for the heads up.

GetFiles can only match a single pattern, but you can use Linq to invoke GetFiles with multiple patterns:

FileInfo[] fi = new string[]{"*.txt","*.doc"}
    .SelectMany(i => di.GetFiles(i, SearchOption.AllDirectories))
    .ToArray();

In your View try like this

  <img src= "@Url.Content(Model.ImagePath)" alt="Image" />

I use getActionCommand() to hear buttons. I apply the setActionCommand() to each button so that I can hear whenever an event is execute with event.getActionCommand("The setActionCommand() value of the button").

I use getSource() for JRadioButtons for example. I write methods that returns each JRadioButton so in my Listener Class I can specify an action each time a new JRadioButton is pressed. So for example:

public class SeleccionListener implements ActionListener, FocusListener {}

So with this I can hear button events and radioButtons events. The following are examples of how I listen each one:

public void actionPerformed(ActionEvent event) {
    if (event.getActionCommand().equals(GUISeleccion.BOTON_ACEPTAR)) {
        System.out.println("Aceptar pressed");
    }

In this case GUISeleccion.BOTON_ACEPTAR is a "public static final String" which is used in JButtonAceptar.setActionCommand(BOTON_ACEPTAR).

public void focusGained(FocusEvent focusEvent) {
    if (focusEvent.getSource().equals(guiSeleccion.getJrbDat())){
        System.out.println("Data radio button");
    }

In this one, I get the source of any JRadioButton that is focused when the user hits it. guiSeleccion.getJrbDat() returns the reference to the JRadioButton that is in the class GUISeleccion (this is a Frame)

Try simply to reset last commit using --soft flag

git reset --soft HEAD~1

Note :

For Windows, wrap the HEAD parts in quotes like git reset --soft "HEAD~1"

and add this in the controller:

public ActionResult _Header(ViewAsModelBase model)

Use encode() function along with hardcoded String value given in a single quote.

Ex:

file.write(answers[i] + '\n'.encode())

OR

line.split(' +++$+++ '.encode())

Something like (Found at Delete All Procedures from a database using a Stored procedure in SQL Server).

Just so by the way, this seems like a VERY dangerous thing to do, just a thought...

declare @procName varchar(500)
declare cur cursor 

for select [name] from sys.objects where type = 'p'
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec('drop procedure [' + @procName + ']')
    fetch next from cur into @procName
end
close cur
deallocate cur

I made this implementation in kotlin I thing is not very efficient but works ivIsSelected is a ImageView that represent in my case a check mark

var selectedItems = mutableListOf<Int>(-1)

override fun onBindViewHolder(holder: ContactViewHolder, position: Int) {
    // holder.setData(ContactViewModel, position)  // I'm passing this to the ViewHolder
    holder.itemView.setBackgroundColor(Color.WHITE)   
    holder.itemView.ivIsSelected.visibility = INVISIBLE
    selectedItems.forEach {
        if (it == position) {
            holder.itemView.setBackgroundColor(Color.argb(45, 0, 255, 43))
            holder.itemView.ivIsSelected.visibility = VISIBLE
        }
    }

    holder.itemView.setOnClickListener { it ->
        it.setBackgroundColor(Color.BLUE)  
        selectedItems.add(position)
        selectedItems.forEach { selectedItem ->  // this forEach is required to refresh all the list
            notifyItemChanged(selectedItem)
        }

    }
}

If you happen to use [Py]Qt already, you may be interested in qimage2ndarray. Starting with version 1.4 (just released), PySide is supported as well, and there will be a tiny imsave(filename, array) function similar to scipy's, but using Qt instead of PIL. With 1.3, just use something like the following:

qImage = array2qimage(image, normalize = False) # create QImage from ndarray
success = qImage.save(filename) # use Qt's image IO functions for saving PNG/JPG/..

(Another advantage of 1.4 is that it is a pure python solution, which makes this even more lightweight.)

In Manifest theme sets with style name (AppTheme and myDialog)/ You can set new styles in styles.xml

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MyActivity2"
        android:label="@string/title_activity_my_activity2"
        android:theme="@style/myDialog"
        >
    </activity>
</application>

styles.xml example

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Black">
    <!-- Customize your theme here. -->
</style>

<style name="myDialog" parent="android:Theme.Dialog">

</style>

In parent you set actualy the theme

You can also use rcParams to change the font family globally.

 import matplotlib.pyplot as plt
 plt.rcParams["font.family"] = "cursive"
 # This will change to your computer's default cursive font

The list of matplotlib's font family arguments is here.

You can use the required html attribute if you want:

@Html.TextBoxFor(m => m.ShortName, 
new { @class = "form-control", placeholder = "short name", required="required"})

or you can use the RequiredAttribute class in .Net. With jQuery the RequiredAttribute can Validate on the front end and server side. If you want to go the MVC route, I'd suggest reading Data annotations MVC3 Required attribute.

OR

You can get really advanced:

@{
  // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
  var attributes = new Dictionary<string, object>(
    Html.GetUnobtrusiveValidationAttributes(ViewData.TemplateInfo.HtmlFieldPrefix));

 attributes.Add("class", "form-control");
 attributes.Add("placeholder", "short name");

  if (ViewData.ModelMetadata.ContainerType
      .GetProperty(ViewData.ModelMetadata.PropertyName)
      .GetCustomAttributes(typeof(RequiredAttribute), true)
      .Select(a => a as RequiredAttribute)
      .Any(a => a != null))
  {
   attributes.Add("required", "required");
  }

  @Html.TextBoxFor(m => m.ShortName, attributes)

}

or if you need it for multiple editor templates:

public static class ViewPageExtensions
{
  public static IDictionary<string, object> GetAttributes(this WebViewPage instance)
  {
    // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
    var attributes = new Dictionary<string, object>(
      instance.Html.GetUnobtrusiveValidationAttributes(
         instance.ViewData.TemplateInfo.HtmlFieldPrefix));

    if (ViewData.ModelMetadata.ContainerType
      .GetProperty(ViewData.ModelMetadata.PropertyName)
      .GetCustomAttributes(typeof(RequiredAttribute), true)
      .Select(a => a as RequiredAttribute)
      .Any(a => a != null))
    {
      attributes.Add("required", "required");
    }
  }
}

then in your templates:

@{
  // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
  var attributes = this.GetAttributes();

  attributes.Add("class", "form-control");
  attributes.Add("placeholder", "short name");

  @Html.TextBoxFor(m => m.ShortName, attributes)

}

Update 1 (for Tomas who is unfamilar with ViewData).

What's the difference between ViewData and ViewBag?

Excerpt:

So basically it (ViewBag) replaces magic strings:

ViewData["Foo"]

with magic properties:

ViewBag.Foo

What type is the seahawk.flags variable?

In standard C++, enumerations are not type-safe. They are effectively integers.

AnimalFlags should NOT be the type of your variable. Your variable should be int and the error will go away.

Putting hexadecimal values like some other people suggested is not needed. It makes no difference.

The enum values ARE of type int by default. So you can surely bitwise OR combine them and put them together and store the result in an int.

The enum type is a restricted subset of int whose value is one of its enumerated values. Hence, when you make some new value outside of that range, you can't assign it without casting to a variable of your enum type.

You can also change the enum value types if you'd like, but there is no point for this question.

EDIT: The poster said they were concerned with type safety and they don't want a value that should not exist inside the int type.

But it would be type unsafe to put a value outside of AnimalFlags's range inside a variable of type AnimalFlags.

There is a safe way to check for out of range values though inside the int type...

int iFlags = HasClaws | CanFly;
//InvalidAnimalFlagMaxValue-1 gives you a value of all the bits 
// smaller than itself set to 1
//This check makes sure that no other bits are set.
assert(iFlags & ~(InvalidAnimalFlagMaxValue-1) == 0);

enum AnimalFlags {
    HasClaws = 1,
    CanFly =2,
    EatsFish = 4,
    Endangered = 8,

    // put new enum values above here
    InvalidAnimalFlagMaxValue = 16
};

The above doesn't stop you from putting an invalid flag from a different enum that has the value 1,2,4, or 8 though.

If you want absolute type safety then you could simply create a std::set and store each flag inside there. It is not space efficient, but it is type safe and gives you the same ability as a bitflag int does.

C++0x note: Strongly typed enums

In C++0x you can finally have type safe enum values....

enum class AnimalFlags {
    CanFly = 2,
    HasClaws = 4
};

if(CanFly == 2) { }//Compiling error

The output of the error, is because you call an index of the Array that does not exist, for example

$arr = Array(1,2,3);
echo $arr[3]; 
// Error PHP Notice:  Undefined offset: 1 pointer 3 does not exist, the array only has 3 elements but starts at 0 to 2, not 3!

You need to make sure that the value you pass to the directory argument is an absolute path, corrected for the current location of your application.

The best way to do this is to configure UPLOAD_FOLDER as a relative path (no leading slash), then make it absolute by prepending current_app.root_path:

@app.route('/uploads/<path:filename>', methods=['GET', 'POST'])
def download(filename):
    uploads = os.path.join(current_app.root_path, app.config['UPLOAD_FOLDER'])
    return send_from_directory(directory=uploads, filename=filename)

It is important to reiterate that UPLOAD_FOLDER must be relative for this to work, e.g. not start with a /.

A relative path could work but relies too much on the current working directory being set to the place where your Flask code lives. This may not always be the case.

Instead of above way u can achieve the solution simply by following method..

public static void main(String args[]) {
    String ini = "Hi there";
    for (int i = 0; i < ini.length(); i++) {
        System.out.print(" " + ini.charAt(i));
    }
}

Since your controller actions execute on the server, and JavaScript (usually) executes on the client (browser), this doesn't make sense. If you need some action to happen by default once the page is loaded into the browser, you can use JavaScript's document.OnLoad event handler.

I encountered the same thing lately. it was just due to spaces when copying a script from a document to sql developer. I had to remove the spaces and the script ran.

This answer concerns developers for Windows. You want to pick an XML parsing module that does NOT depend on node-expat. Node-expat requires node-gyp and node-gyp requires you to install Visual Studio on your machine. If your machine is a Windows Server, you definitely don't want to install Visual Studio on it.

So, which XML parsing module to pick?

Save yourself a lot of trouble and use either xml2js or xmldoc. They depend on sax.js which is a pure Javascript solution that doesn't require node-gyp.

Both libxmljs and xml-stream require node-gyp. Don't pick these unless you already have Visual Studio on your machine installed or you don't mind going down that road.

Update 2015-10-24: it seems somebody found a solution to use node-gyp on Windows without installing VS: https://github.com/nodejs/node-gyp/issues/629#issuecomment-138276692

This would print the files in those directories line by line.

array=(ww/* ee/* qq/*)
printf "%s\n" "${array[@]}"

You will not able to convert it into data frame until you use implicit conversion.

val sqlContext = new SqlContext(new SparkContext())

import sqlContext.implicits._

After this only you can convert this to data frame

case class Test(id:String,filed2:String)

val myFile = sc.textFile("file.txt")

val df= myFile.map( x => x.split(";") ).map( x=> Test(x(0),x(1)) ).toDF()

By pressing 'Enter' on focused <input type="text"> you trigger 'click' event on the first positioned element: <button> or <input type="submit">. If you press 'Enter' in <textarea>, you just make a new text line.

See the example here.

Your code prevents to make a new text line in <textarea>, so you have to catch key press only for <input type="text">.

But why do you need to press Enter in text field? If you want to submit form by pressing 'Enter', but the <button> must stay the first in the layout, just play with the markup: put the <input type="submit"> code before the <button> and use CSS to save the layout you need.

Catching 'Enter' and saving markup:

$('input[type="text"]').keypress(function (e) {
    var code = e.keyCode || e.which;
    if (code === 13)
    e.preventDefault();
    $("form").submit(); /*add this, if you want to submit form by pressing `Enter`*/
});

USEFUL PATH PROPERTIES IN PYTHON:

 from pathlib import Path

    #Returns the path of the directory, where your script file is placed
    mypath = Path().absolute()
    print('Absolute path : {}'.format(mypath))

    #if you want to go to any other file inside the subdirectories of the directory path got from above method
    filePath = mypath/'data'/'fuel_econ.csv'
    print('File path : {}'.format(filePath))

    #To check if file present in that directory or Not
    isfileExist = filePath.exists()
    print('isfileExist : {}'.format(isfileExist))

    #To check if the path is a directory or a File
    isadirectory = filePath.is_dir()
    print('isadirectory : {}'.format(isadirectory))

    #To get the extension of the file
    fileExtension = mypath/'data'/'fuel_econ.csv'
    print('File extension : {}'.format(filePath.suffix))

OUTPUT: ABSOLUTE PATH IS THE PATH WHERE YOUR PYTHON FILE IS PLACED

Absolute path : D:\Study\Machine Learning\Jupitor Notebook\JupytorNotebookTest2\Udacity_Scripts\Matplotlib and seaborn Part2

File path : D:\Study\Machine Learning\Jupitor Notebook\JupytorNotebookTest2\Udacity_Scripts\Matplotlib and seaborn Part2\data\fuel_econ.csv

isfileExist : True

isadirectory : False

File extension : .csv

If a string must not contain @, every character must be another character than @:

/^[^@]*$/

This will match any string of any length that does not contain @.

Another possible solution would be to invert the boolean result of /@/.

var hello = $('.right') // or var hello = document.getElementByClassName('right')
var bye = $('.right1')
hello.onmouseover = function()
{
    bye.style.visibility = 'visible'
}
hello.onmouseout = function()
{
    bye.style.visibility = 'hidden'
}

(In reply to user672009 above.)

An even easier solution, if you want to keep your passwords out of a git repository; yet, want to include your build.gradle in it, that even works great with product flavors, is to create a separate gradle file. Let's call it 'signing.gradle' (include it in your .gitignore). Just as if it were your build.gradle file minus everything not related to signing in it.

android {
    signingConfigs { 
        flavor1 {
            storeFile file("..")
            storePassword ".."
            keyAlias ".."
            keyPassword ".."
        }
        flavor2 {
            storeFile file("..")
            storePassword ".."
            keyAlias ".."
            keyPassword ".."
        }
    }
}

Then in your build.gradle file include this line right underneath "apply plugin: 'android'"

 apply from: 'signing.gradle'

If you don't have or use multiple flavors, rename "flavor1" to "release" above, and you should be finished. If you are using flavors continue.

Finally link your flavors to its correct signingConfig in your build.gradle file and you should be finished.

  ...

  productFlavors {

      flavor1 {
          ...
          signingConfig signingConfigs.flavor1
      }

      flavor2 {
          ...
          signingConfig signingConfigs.flavor2
      }
  }

For me this error was caused by DotNetOpenAuth not being compatible with MVC5 after upgrading from MVC4 to MVC5. Uninstalling Microsoft.Web.WebPages.OAuth fixed the problem.

I found an example POM for the Servlet 3.0 API on DZone from September.

Suggest you use the java.net repo, at http://download.java.net/maven/2/

There are Java EE APIs in there, for example http://download.java.net/maven/2/javax/javaee-web-api/6.0/ with POM that look like they might be what you're after, for example:

<dependency>
  <groupId>javax</groupId>
  <artifactId>javaee-web-api</artifactId>
  <version>6.0</version>
</dependency>

I'm guessing that the version conventions for the APIs have been changed to match the version of the overall EE spec (i.e. Java EE 6 vs. Servlets 3.0) as part of the new 'profiles'. Looking in the JAR, looks like all the 3.0 servlet stuff is in there. Enjoy!

Maybe try putting it all in the end if and use a else to skip the code this will make it so that you are able not use the GoTo.

                        If 6 - ((Int_height(Int_Column - 1) - 1) + Int_direction(e, 1)) = 7 Or (Int_Column - 1) + Int_direction(e, 0) = -1 Or (Int_Column - 1) + Int_direction(e, 0) = 7 Then
                Else
                    If Grid((Int_Column - 1) + Int_direction(e, 0), 6 - ((Int_height(Int_Column - 1) - 1) + Int_direction(e, 1))) = "_" Then
                        Console.ReadLine()
                    End If
                End If

In Ubuntu

Step 1:

sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

Step 2: Go to last line and add the following

sql_mode = ""

Step 3: Save

Step 4: Restart mysql server.

I am using Windows 7, the problem I had was simple:

I had this for my JAVA_HOME environment variable value:

"C:\Program Files\Java\jdk1.7.0_51;"

when it wants:

"C:\Program Files\Java\jdk1.7.0_51"

the semi-colon strikes again!

:)

This is how I solved this problem, so this should be one possible solution.

BLEUscore

BLEU, or the Bilingual Evaluation Understudy, is a score for comparing a candidate translation of text to one or more reference translations.

A perfect match results in a score of 1.0, whereas a perfect mismatch results in a score of 0.0.

Although developed for translation, it can be used to evaluate text generated for a suite of natural language processing tasks.

Code:

import nltk
from nltk.translate import bleu
from nltk.translate.bleu_score import SmoothingFunction
smoothie = SmoothingFunction().method4

C1='Text'
C2='Best'

print('BLEUscore:',bleu([C1], C2, smoothing_function=smoothie))

Examples: By updating C1 and C2.

C1='Test' C2='Test'

BLEUscore: 1.0

C1='Test' C2='Best'

BLEUscore: 0.2326589746035907

C1='Test' C2='Text'

BLEUscore: 0.2866227639866161

You can also compare sentence similarity:

C1='It is tough.' C2='It is rough.'

BLEUscore: 0.7348889200874658

C1='It is tough.' C2='It is tough.'

BLEUscore: 1.0

You're probably not actually signing the release build of the APK via the signing wizard. You can either build the release APK from the command line with the command:

./gradlew assembleRelease

or you can choose the release variant from the Build Variants view and build it from the GUI:

You can use a regular expression: window.location.href.match(/^[^\#\?]+/)[0]

Render Line Endings is a VS Code extension that is still actively maintained (as of Apr 2020):

https://marketplace.visualstudio.com/items?itemName=medo64.render-crlf

It can be configured like this:

{
    "editor.renderWhitespace": "all",
    "code-eol.newlineCharacter": "¬",
    "code-eol.returnCharacter" : "¤",
    "code-eol.crlfCharacter"   : "¤¬",
}

and looks like this:

To update database type following codes in PowerShell...

Update-Database -context EnrollmentAppContext

*if more than one databases exist only use this codes,otherwise not necessary..

Quote:

The "BIGINT(20)" specification isn't a digit limit. It just means that when the data is displayed, if it uses less than 20 digits it will be left-padded with zeros. 2^64 is the hard limit for the BIGINT type, and has 20 digits itself, hence BIGINT(20) just means everything less than 10^20 will be left-padded with spaces on display.

You can use PowerShell to get the information you want.

(Get-Item C:\Path\To\MyFile.dll).VersionInfo

By default this will display ProductVersion and FileVersion But the full VERSIONINFO is available. I.e. to return Comments

Here the steps I used to fix the warning:

• Unload project in VS
• Edit .csproj file
• Search for all references to Newtonsoft.Json assembly
  • Found two, one to v6 and one to v5
  • Replace the reference to v5 with v6
• Reload project
• Build and notice assembly reference failure
• View References and see that there are now two to Newtonsoft.Json. Remove the one that's failing to resolve.
• Rebuild - no warnings

There is a new API that makes this even simpler.

I had the same issue but when i deleted the cached items from Temp folder the build failed.

In order to make the build work again I had to close the project and reopen it.

Use the pip application. On windows you find it in Python3/Scripts/pip.exe and On Ubuntu you can install with apt-get install python3-pip. and so, use the command line:

pip3 install --upgrade pip

pip3 install opencv-python

On Windows use only pip.exe instead pip3

We can use following one liner in Java 8:

List<String> list = set.stream().collect(Collectors.toList());

Here is one small example:

public static void main(String[] args) {
        Set<String> set = new TreeSet<>();
        set.add("A");
        set.add("B");
        set.add("C");
        List<String> list = set.stream().collect(Collectors.toList());
}

To use Thickness you need to create/change your project .NET framework platform version to 4.5. becaus this method available only in version 4.5. (Also you can just download PresentationFramework.dll and give referense to this dll, without create/change your .NET framework version to 4.5.)

But if you want to do this simple, You can use this code:

MyControl.Margin = new Padding(int left, int top, int right, int bottom);

also

MyControl.Margin = new Padding(int all);

This is simple and no needs any changes to your project

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

This should do it:

ALTER TABLE test MODIFY locationExpert VARCHAR(120) 

It is very simple.. Here you go !!

There is a really nice trick. My problem was that some really old C++ jni library leaked resources. At some point, it stopped functioning. The user tried to exit the app and launch it again -- with no result, because finishing an activity is not the same as finishing (or killing) the process. (By the way, the user could go to the list of the running applications and stop it from there -- this would work, but the users just do not know how to terminate applications.)

If you want to observe the effect of this feature, add a static variable to your activity and increment it each, say, button press. If you exit the application activity and then invoke the application again, this static variable will keep its value. (If the application really was exited, the variable would be assigned the initial value.)

(And I have to comment on why I did not want to fix the bug instead. The library was written decades ago and leaked resources ever since. The management believes it always worked. The cost of providing a fix instead of a workaround... I think, you get the idea.)

Now, how could I reset a jni shared (a.k.a. dynamic, .so) library to the initial state? I chose to restart application as a new process.

The trick is that System.exit() closes the current activity and Android recreates the application with one activity less.

So the code is:

/** This activity shows nothing; instead, it restarts the android process */
public class MagicAppRestart extends Activity {
    // Do not forget to add it to AndroidManifest.xml
    // <activity android:name="your.package.name.MagicAppRestart"/>
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        System.exit(0);
    }
    public static void doRestart(Activity anyActivity) {
        anyActivity.startActivity(new Intent(anyActivity.getApplicationContext(), MagicAppRestart.class));
    }
}

The calling activity just executes the code MagicAppRestart.doRestart(this);, the calling activity's onPause() is executed, and then the process is re-created. And do not forget to mention this activity in AndroidManifest.xml

The advantage of this method is that there is no delays.

UPD: it worked in Android 2.x, but in Android 4 something has changed.

C# has two "equals" concepts: Equals and ReferenceEquals. For most classes you will encounter, the == operator uses one or the other (or both), and generally only tests for ReferenceEquals when handling reference types (but the string Class is an instance where C# already knows how to test for value equality).

• Equals compares values. (Even though two separate int variables don't exist in the same spot in memory, they can still contain the same value.)
• ReferenceEquals compares the reference and returns whether the operands point to the same object in memory.

Example Code:

var s1 = new StringBuilder("str");
var s2 = new StringBuilder("str");
StringBuilder sNull = null;

s1.Equals(s2); // True
object.ReferenceEquals(s1, s2); // False
s1 == s2 // True - it calls Equals within operator overload

s1.Equals(sNull); // Nono!  Explode (Exception)

For the links which contains common url have to console in a variable. Then attempt it sequentially.

webelements allLinks=driver.findelements(By.xpath("//a[contains(@href,'http://122.11.38.214/dl/appdl/application/apk')]"));
int linkCount=allLinks.length();
for(int i=0; <linkCount;i++)
{
    driver.findelement(allLinks[i]).click();
}

Look at how the current Object Results are created. Here is the BadRequestObjectResult. Just an extension of the ObjectResult with a value and StatusCode.

https://github.com/aspnet/Mvc/blob/master/src/Microsoft.AspNetCore.Mvc.Core/BadRequestObjectResult.cs

I created a TimeoutExceptionObjectResult just the same way for 408.

/// <summary>
/// An <see cref="ObjectResult"/> that when executed will produce a Request Timeout (408) response.
/// </summary>
[DefaultStatusCode(DefaultStatusCode)]
public class TimeoutExceptionObjectResult : ObjectResult
{
    private const int DefaultStatusCode = StatusCodes.Status408RequestTimeout;

    /// <summary>
    /// Creates a new <see cref="TimeoutExceptionObjectResult"/> instance.
    /// </summary>
    /// <param name="error">Contains the errors to be returned to the client.</param>
    public TimeoutExceptionObjectResult(object error)
        : base(error)
    {
        StatusCode = DefaultStatusCode;
    }
}

Client:

if (ex is TimeoutException)
{
    return new TimeoutExceptionObjectResult("The request timed out.");
}

One possible answer will be given when you run this snippet.

document.write('<table>')_x000D_
for (var i = 0; i < 250; i++) {_x000D_
  document.write('<tr><td>' + i + '</td><td>' + String.fromCharCode(i) + '</td></tr>')_x000D_
}_x000D_
document.write('</table>')

td {_x000D_
  border: solid 1px;_x000D_
  padding: 1px 12px;_x000D_
  text-align: right;_x000D_
}_x000D_
table {_x000D_
  border-collapse: collapse;_x000D_
}_x000D_
* {_x000D_

}

I had this problem and it turned out I was trying to restore to the wrong version of SQL. If you want more information on what's going on, try restoring the database using the following SQL:

RESTORE DATABASE <YourDatabase> 
FROM DISK='<the path to your backup file>\<YourDatabase>.bak'

That should give you the error message that you need to debug this.

The argument to remove() is a filter document, so passing in an empty document means 'remove all':

db.user.remove({})

However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove() call vs the drop() call.

More details in the docs.

You can use:

  import ipy_autoreload
  %autoreload 2 
  %aimport your_mod

For AWS S3, setting the Cross-origin resource sharing (CORS) to the following worked for me:

[
    {
        "AllowedHeaders": [
            "Authorization"
        ],
        "AllowedMethods": [
            "GET",
            "HEAD"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": []
    }
]

Newer Edit: Lots of things have changed since this question was initially posted - there's a lot of really good information in wallacer's revised answer as well as VisioN's excellent breakdown

Edit: Just because this is the accepted answer; wallacer's answer is indeed much better:

return filename.split('.').pop();

My old answer:

return /[^.]+$/.exec(filename);

Should do it.

Edit: In response to PhiLho's comment, use something like:

return (/[.]/.exec(filename)) ? /[^.]+$/.exec(filename) : undefined;

Ensure that you have turned ON the location services on the device. Else you won't get any location related info.

This works for me,

    map = ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
    map.setMyLocationEnabled(true);
    GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() {
        @Override
        public void onMyLocationChange (Location location) {
           LatLng loc = new LatLng (location.getLatitude(), location.getLongitude());
           map.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
        }
    };
    map.setOnMyLocationChangeListener(myLocationChangeListener);

}

Ctrl-K, Ctrl-D

Will just prettify the entire document. Saves a lot of messing about, compared to delphi.

Make sure to remove all indents by first selecting everything with Ctrl+A then press Shift+Tab repeatedly until everything is aligned to the left. After you do that Ctrl+K, Ctrl+D will work the way you want them to.

You could also do the same but only to a selection of code by highlighting the block of code you want to realign, aligning it to the left side (Shift+Tab) and then after making sure you've selected the code you want to realign press Ctrl+K, Ctrl+F or just right click the highlighted code and select "Format Selection".

moving average

iterator method

• reverse the array at i, and simply take the mean from i to n.

• use list comprehension to generate mini arrays on the fly.

x = np.random.randint(10, size=20)

def moving_average(arr, n):
    return [ (arr[:i+1][::-1][:n]).mean() for i, ele in enumerate(arr) ]
d = 5

moving_average(x, d)

tensor convolution

moving_average = np.convolve(x, np.ones(d)/d, mode='valid')

SQL Server 2016 SP2 CU6 and SQL Server 2017 CU12 introduced trace flag 460 in order to return the details of truncation warnings. You can enable it at the query level or at the server level.

Query level

INSERT INTO dbo.TEST (ColumnTest)
VALUES (‘Test truncation warnings’)
OPTION (QUERYTRACEON 460);
GO

Server Level

DBCC TRACEON(460, -1);
GO

From SQL Server 2019 you can enable it at database level:

ALTER DATABASE SCOPED CONFIGURATION 
SET VERBOSE_TRUNCATION_WARNINGS = ON;

The old output message is:

Msg 8152, Level 16, State 30, Line 13
String or binary data would be truncated.
The statement has been terminated.

The new output message is:

Msg 2628, Level 16, State 1, Line 30
String or binary data would be truncated in table 'DbTest.dbo.TEST', column 'ColumnTest'. Truncated value: ‘Test truncation warnings‘'.

In a future SQL Server 2019 release, message 2628 will replace message 8152 by default.

Looks like you need something along the lines of this: Git checkout based on date

In other words, you use rev-list to find the commit and then use checkout to actually get it.

If you don't want to lose your staged changes, the easiest thing would be to create a new branch and commit them to that branch. You can always switch back and forth between branches.

Edit: The link is down, so here's the command:

git checkout `git rev-list -n 1 --before="2009-07-27 13:37" master`

This is how I organized my application's static resources.

Add to the selector containing the text

margin:auto;

GreenSock Animation Platform (GSAP) with TweenLite / TweenMax provides much smoother transitions with far greater customization than jQuery or CSS3 transitions. In order to animate CSS properties with TweenLite / TweenMax, you'll also need their plugin called "CSSPlugin". TweenMax includes this automatically.

First, load the TweenMax library:

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/TweenMax.min.js"></script>

Or the lightweight version, TweenLite:

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/plugins/CSSPlugin.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/easing/EasePack.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/TweenLite.min.js"></script>

Then, call your animation:

 var myObj= document.getElementById("myDiv");

// Syntax: (target, speed, {distance, ease})
 TweenLite.to(myObj, .7, { x: 500, ease: Power3.easeOut});

You can also call it with an ID selector:

 TweenLite.to("#myID", .7, { x: 500, ease: Power3.easeOut});

If you have jQuery loaded, you can use more advanced broad selectors, like all elements containing a specific class:

 // This will parse the selectors using jQuery's engine.
TweenLite.to(".myClass", .7, { x: 500, ease: Power3.easeOut});

For full details, see: TweenLite Documentation

According to their website: "TweenLite is an extremely fast, lightweight, and flexible animation tool that serves as the foundation of the GreenSock Animation Platform (GSAP)."

Using rowid-

delete from emp
 where rowid not in
 (select max(rowid) from emp group by empno);

Using self join-

delete from emp e1
 where rowid not in
 (select max(rowid) from emp e2
 where e1.empno = e2.empno );

Looking at the code always helps too. That is, you can actually take a look at the generated partial class (that calls LoadComponent) by doing the following:

1. Go to the Solution Explorer pane in the Visual Studio solution that you are interested in.
2. There is a button in the tool bar of the Solution Explorer titled 'Show All Files'. Toggle that button.
3. Now, expand the obj folder and then the Debug or Release folder (or whatever configuration you are building) and you will see a file titled YourClass.g.cs.

The YourClass.g.cs ... is the code for generated partial class. Again, if you open that up you can see the InitializeComponent method and how it calls LoadComponent ... and much more.

I recently had same issue with Spring 4.0.

It was caused by a collision in names from spring-beans-4.0.xsd and spring-context-4.0.xsd. Opening spring-context-4.0.xsd you can see that spring-beans-4.0.xsd is imported like follow:

<xsd:import namespace="http://www.springframework.org/schema/beans"  
schemaLocation="http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"/>

These name's collisions make Eclipse complain about "...A schema cannot contain two global components with the same name..."

A noteworthy aspect is that I hadn't this problem with Eclipse Kepler SR2 but Eclipse Luna SR1, comparing both preferences about XML Validation, they were the same.

It was solved by removing spring-context-4.0.xsd from xsi:schemaLocation attribute:

http://www.springframework.org/schema/context   
http://www.springframework.org/schema/context/spring-context-4.0.xsd

After this everything worked as expected.

To allow for compound commands to be echoed, I use eval plus Soth's exe function to echo and run the command. This is useful for piped commands that would otherwise only show none or just the initial part of the piped command.

Without eval:

exe() { echo "\$ $@" ; "$@" ; }
exe ls -F | grep *.txt

Outputs:

$
file.txt

With eval:

exe() { echo "\$ $@" ; "$@" ; }
exe eval 'ls -F | grep *.txt'

Which outputs

$ exe eval 'ls -F | grep *.txt'
file.txt

If you want to update matching rows in t1 with data from t2 then:

update t1
set (c1, c2, c3) = 
(select c1, c2, c3 from t2
 where t2.user_id = t1.user_id)
where exists
(select * from t2
 where t2.user_id = t1.user_id)

The "where exists" part it to prevent updating the t1 columns to null where no match exists.

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col
Next

string theString = "The String";
int index = theString.NthIndexOf("THEVALUE", 3, true);

Use ifelse:

frame$twohouses <- ifelse(frame$data>=2, 2, 1)
frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
...
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

The difference between if and ifelse:

• if is a control flow statement, taking a single logical value as an argument
• ifelse is a vectorised function, taking vectors as all its arguments.

The help page for if, accessible via ?"if" will also point you to ?ifelse

You can have a regular Python module, say config.py, like this:

truck = dict(
    color = 'blue',
    brand = 'ford',
)
city = 'new york'
cabriolet = dict(
    color = 'black',
    engine = dict(
        cylinders = 8,
        placement = 'mid',
    ),
    doors = 2,
)

and use it like this:

import config
print(config.truck['color'])  

Improving the first answer just get rid of the padding and add line-height and vertical-align:

.numberCircle {
   border-radius: 50%;       

   width: 36px;
   height: 36px;
   line-height: 36px;
   vertical-align:middle;

   background: #fff;
   border: 2px solid #666;
   color: #666;

   text-align: center;
   font: 32px Arial, sans-serif;
}

you can use this

List<Car> requiredCars = cars.stream()
    .filter (t->  t!= null && StringUtils.startsWith(t.getName(),"M"))
    .collect(Collectors.toList());

AppActivate!

If you don't mind muddying your references a bit, you can include Microsoft.Visualbasic, and use this very short way.

Display the MessageBox

    (new System.Threading.Thread(CloseIt)).Start();
    MessageBox.Show("HI");

CloseIt Function:

public void CloseIt()
{
    System.Threading.Thread.Sleep(2000);
    Microsoft.VisualBasic.Interaction.AppActivate( 
         System.Diagnostics.Process.GetCurrentProcess().Id);
    System.Windows.Forms.SendKeys.SendWait(" ");
}

Now go wash your hands!

<script type="text/javascript">
function bike()
{
var data=
["b1.jpg", "b2.jpg", "b3.jpg", "b4.jpg", "b5.jpg", "b6.jpg", "b7.jpg", "b8.jpg"];
var a;
for(a=0; a<data.length; a++)
{
document.write("<center><fieldset style='height:200px; float:left; border-radius:15px; border-width:6px;")<img src='"+data[a]+"' height='200px' width='300px'/></fieldset></center>
}
}

Do you realy want to return null ? Something you can do, is maybe initialise savedkey with 0 value and return 0 as a null value. It can be more simple.

One or more of your .cpp files is not being linked in, or some non-inline functions in some class are not defined. In particular, takeaway::textualGame()'s implementation can't be found. Note that you've defined a textualGame() at toplevel, but this is distinct from a takeaway::textualGame() implementation - probably you just forgot the takeaway:: there.

What the error means is that the linker can't find the "vtable" for a class - every class with virtual functions has a "vtable" data structure associated with it. In GCC, this vtable is generated in the same .cpp file as the first listed non-inline member of the class; if there's no non-inline members, it will be generated wherever you instantiate the class, I believe. So you're probably failing to link the .cpp file with that first-listed non-inline member, or never defining that member in the first place.
