Programs & Examples On #Continued fractions

The with function will let you use shorthand column references and sum will count TRUE results from the expression(s).

sum(with(aaa, sex==1 & group1==2))
## [1] 3

sum(with(aaa, sex==1 & group2=="A"))
## [1] 2

As @mnel pointed out, you can also do:

nrow(aaa[aaa$sex==1 & aaa$group1==2,])
## [1] 3

nrow(aaa[aaa$sex==1 & aaa$group2=="A",])
## [1] 2

The benefit of that is that you can do:

nrow(aaa)
## [1] 6

And, the behaviour matches Stata's count almost exactly (syntax notwithstanding).

OneToOneField (Example: one car has one owner) ForeignKey(OneToMany) (Example: one restaurant has many items)

All of these answers are wrong! Do not use InsecureSkipVerify to deal with a CN that doesn't match the hostname. The Go developers unwisely were adamant about not disabling hostname checks (which has legitimate uses - tunnels, nats, shared cluster certs, etc), while also having something that looks similar but actually completely ignores the certificate check. You need to know that the certificate is valid and signed by a cert that you trust. But in common scenarios, you know that the CN won't match the hostname you connected with. For those, set ServerName on tls.Config. If tls.Config.ServerName == remoteServerCN, then the certificate check will succeed. This is what you want. InsecureSkipVerify means that there is NO authentication; and it's ripe for a Man-In-The-Middle; defeating the purpose of using TLS.

There is one legitimate use for InsecureSkipVerify: use it to connect to a host and grab its certificate, then immediately disconnect. If you setup your code to use InsecureSkipVerify, it's generally because you didn't set ServerName properly (it will need to come from an env var or something - don't belly-ache about this requirement... do it correctly).

In particular, if you use client certs and rely on them for authentication, you basically have a fake login that doesn't actually login any more. Refuse code that does InsecureSkipVerify, or you will learn what is wrong with it the hard way!

I came up with this pretty basic code. I think it could be useful to anyone.

$link = "link to the CSV here"
$fp = fopen($link, 'r');

while(($line = fgetcsv($fp)) !== FALSE) {
    foreach($line as $key => $value) {
        echo $key . " - " . $value . "<br>";
    }
}


fclose($fp);

If you're attempting to do this in a .NET Standard library, here's a simple solution, with all of the risks of just returning true in your handler. I leave safety up to you.

var handler = new HttpClientHandler();
handler.ClientCertificateOptions = ClientCertificateOption.Manual;
handler.ServerCertificateCustomValidationCallback = 
    (httpRequestMessage, cert, cetChain, policyErrors) =>
{
    return true;
};

var client = new HttpClient(handler);

To get around the process launch failed: Security issue and immediately launch the app on your device, tap the app icon on your iOS device after running the app via Xcode.

This will allow you to immediately run the app. It may not actually "fix" the root issue that is causing these permission alerts.

Be sure to tap the app icon while the Xcode alert is still shown. Otherwise the app will not run. I continually forget this vital step and am unable to run the app on my device. Thus I am documenting it here for myself and everyone else :)

1. Run the app via Xcode. You will see the security alert below. Do not press OK.

2. On your iOS device, tap the newly installed app icon:

3. After tapping the icon, you should now see an alert asking you to "Trust" the Untrusted App Developer. After doing so the app will immediately run, unconnected to the Xcode debugger.

   • If you do not see this "Trust" alert, you likely pressed "OK" in Xcode too soon. Do not press "OK" on the Xcode alert until after trusting the developer.

4. Finally, go back and press "OK" on the Xcode alert. You will have to re-run the app to connect the running app on your iOS device to the Xcode debugger.

If you want to trigger the keypress or keydown event then all you have to do is:

var e = jQuery.Event("keydown");
e.which = 50; // # Some key code value
$("input").trigger(e);

If the data should survive throughout the application lifecycle and shared among multiple fragments or activities, a Model class might come into consideration, which has got less serialization overhead.

Just updating screenshots to help others as I am using a newer v18, circa 2019.

Here you can select certain tables or go with the default of all. For my own needs I'm indicating just the one table.

Next, there's the "Scripting Options" where you can choose output file, etc. As in multiple answers above (again, I'm just dusting off old answers for newer, v18.4 SQL Server Management Studio) what we're really wanting is under the "Advanced" button. For my own purposes, I need just the data.

Finally, there's a review summary before execution. After executing a report of operations' status is shown.

You can try the some thing like the below LINQ snippet.

string[] allLines = File.ReadAllLines(@"E:\Temp\data.csv");

    var query = from line in allLines
                let data = line.Split(',')
                select new
                {
                    Device = data[0],
                    SignalStrength = data[1],
                    Location = data[2], 
                    Time = data[3],
                    Age = Convert.ToInt16(data[4])
                };

UPDATE: Over a period of time, things evolved. As of now, I would prefer to use this library http://www.aspnetperformance.com/post/LINQ-to-CSV-library.aspx

Make sure HttpClient has access to the full client certificate (including the private key).

You are calling GetCert with a file "ClientCertificate.cer" which leads to the assumption that there is no private key contained - should rather be a pfx file within windows. It may be even better to access the certificate from the windows cert store and search it using the fingerprint.

Be careful when copying the fingerprint: There are some non-printable characters when viewing in cert management (copy the string over to notepad++ and check the length of the displayed string).

You need to subscribe to the KeyDown event on the text box. Then something like this:

private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
    if (!char.IsControl(e.KeyChar) 
       && !char.IsDigit(e.KeyChar) 
       && e.KeyChar != '.' && e.KeyChar != '+' && e.KeyChar != '-'
       && e.KeyChar != '(' && e.KeyChar != ')' && e.KeyChar != '*' 
       && e.KeyChar != '/')
    {
        e.Handled = true;
        return;
    }
    e.Handled=false;
    return;
}

The important thing to know is that if you changed the Handled property to true, it will not process the keystroke. Setting it to false will.

I have a partial answer for you. This is based on what I get from GCC:

__DATE__ gives something like "Jul 27 2012"

__TIME__ gives something like 21:06:19

Put this text in an include file called build_defs.h:

#ifndef BUILD_DEFS_H

#define BUILD_DEFS_H


#define BUILD_YEAR ((__DATE__[7] - '0') * 1000 +  (__DATE__[8] - '0') * 100 + (__DATE__[9] - '0') * 10 + __DATE__[10] - '0')

#define BUILD_DATE ((__DATE__[4] - '0') * 10 + __DATE__[5] - '0')


#if 0
#if (__DATE__[0] == 'J' && __DATE__[1] == 'a' && __DATE__[2] == 'n')
    #define BUILD_MONTH  1
#elif (__DATE__[0] == 'F' && __DATE__[1] == 'e' && __DATE__[2] == 'b')
    #define BUILD_MONTH  2
#elif (__DATE__[0] == 'M' && __DATE__[1] == 'a' && __DATE__[2] == 'r')
    #define BUILD_MONTH  3
#elif (__DATE__[0] == 'A' && __DATE__[1] == 'p' && __DATE__[2] == 'r')
    #define BUILD_MONTH  4
#elif (__DATE__[0] == 'M' && __DATE__[1] == 'a' && __DATE__[2] == 'y')
    #define BUILD_MONTH  5
#elif (__DATE__[0] == 'J' && __DATE__[1] == 'u' && __DATE__[2] == 'n')
    #define BUILD_MONTH  6
#elif (__DATE__[0] == 'J' && __DATE__[1] == 'u' && __DATE__[2] == 'l')
    #define BUILD_MONTH  7
#elif (__DATE__[0] == 'A' && __DATE__[1] == 'u' && __DATE__[2] == 'g')
    #define BUILD_MONTH  8
#elif (__DATE__[0] == 'S' && __DATE__[1] == 'e' && __DATE__[2] == 'p')
    #define BUILD_MONTH  9
#elif (__DATE__[0] == 'O' && __DATE__[1] == 'c' && __DATE__[2] == 't')
    #define BUILD_MONTH 10
#elif (__DATE__[0] == 'N' && __DATE__[1] == 'o' && __DATE__[2] == 'v')
    #define BUILD_MONTH 11
#elif (__DATE__[0] == 'D' && __DATE__[1] == 'e' && __DATE__[2] == 'c')
    #define BUILD_MONTH 12
#else
    #error "Could not figure out month"
#endif
#endif

#define BUILD_HOUR ((__TIME__[0] - '0') * 10 + __TIME__[1] - '0')
#define BUILD_MIN ((__TIME__[3] - '0') * 10 + __TIME__[4] - '0')
#define BUILD_SEC ((__TIME__[6] - '0') * 10 + __TIME__[7] - '0')

#endif // BUILD_DEFS_H

I tested the above with GCC on Linux. It all works great, except for the problem that I can't figure out how to get a number for the month. If you check the section that is under #if 0 you will see my attempt to figure out the month. GCC complains with this message:

error: token ""Jul 27 2012"" is not valid in preprocessor expressions

It would be trivial to convert the three-letter month abbreviation into some sort of unique number; just subtract 'A' from the first letter and 'a' from the second and the third, and then convert to a base-26 number or something. But I want to make it evaluate to 1 for January and so on, and I can't figure out how to do that.

EDIT: I just realized that you asked for strings, not expressions that evaluate to integer values.

I tried to use these tricks to build a static string:

#define BUILD_MAJOR 1
#define BUILD_MINOR 4
#define VERSION STRINGIZE(BUILD_MAJOR) "." STRINGIZE(BUILD_MINOR)

char build_str[] = {
    BUILD_MAJOR + '0', '.' BUILD_MINOR + '0', '.',
    __DATE__[7], __DATE__[8], __DATE__[9], __DATE__[10],
    '\0'
};

GCC complains that "initializer element is not constant" for __DATE__.

Sorry, I'm not sure how to help you. Maybe you can try this stuff with your compiler? Or maybe it will give you an idea.

Good luck.

P.S. If you don't need things to be numbers, and you just want a unique build string, it's easy:

const char *build_str = "Version: " VERSION " " __DATE__ " " __TIME__;

With GCC, this results in something like:

Version: 1.4 Jul 27 2012 21:53:59

Full disclosure I am the author of this package but another way to output JSON or JavaScript objects in a readable way complete with being able skip parts, collapse them, etc. is nodedump, https://github.com/ragamufin/nodedump

In addition, since info locals does not display the arguments to the function you're in, use

(gdb) info args

For example:

int main(int argc, char *argv[]) {
    argc = 6*7;    //Break here.
    return 0;
}

argc and argv won't be shown by info locals. The message will be "No locals."

Reference: info locals command.

Use

driver.findElement(By.linkText("App Configuration")).click()

Other Approaches will be

JavascriptLibrary jsLib = new JavascriptLibrary(); 
jsLib.callEmbeddedSelenium(selenium, "triggerMouseEventAt", elementToClick,"click", "0,0");

or

((JavascriptExecutor) driver).executeScript("arguments[0].click();", elementToClick);

There is nothing built in afaik, but building it yourself should be easy. I would do as you suggest and use reflection to obtain the properties and use them to create the columns of the table. Then I would step through each item in the IEnumerable and create a row for each. The only caveat is if your collection contains items of several types (say Person and Animal) then they may not have the same properties. But if you need to check for it depends on your use.

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

It's important to understand what the = operator in JavaScript does and does not do.

The = operator does not make a copy of the data.

The = operator creates a new reference to the same data.

After you run your original code:

var a = $('#some_hidden_var').val(),
    b = a;

a and b are now two different names for the same object.

Any change you make to the contents of this object will be seen identically whether you reference it through the a variable or the b variable. They are the same object.

So, when you later try to "revert" b to the original a object with this code:

b = a;

The code actually does nothing at all, because a and b are the exact same thing. The code is the same as if you'd written:

b = b;

which obviously won't do anything.

Why does your new code work?

b = { key1: a.key1, key2: a.key2 };

Here you are creating a brand new object with the {...} object literal. This new object is not the same as your old object. So you are now setting b as a reference to this new object, which does what you want.

To handle any arbitrary object, you can use an object cloning function such as the one listed in Armand's answer, or since you're using jQuery just use the $.extend() function. This function will make either a shallow copy or a deep copy of an object. (Don't confuse this with the $().clone() method which is for copying DOM elements, not objects.)

For a shallow copy:

b = $.extend( {}, a );

Or a deep copy:

b = $.extend( true, {}, a );

What's the difference between a shallow copy and a deep copy? A shallow copy is similar to your code that creates a new object with an object literal. It creates a new top-level object containing references to the same properties as the original object.

If your object contains only primitive types like numbers and strings, a deep copy and shallow copy will do exactly the same thing. But if your object contains other objects or arrays nested inside it, then a shallow copy doesn't copy those nested objects, it merely creates references to them. So you could have the same problem with nested objects that you had with your top-level object. For example, given this object:

var obj = {
    w: 123,
    x: {
        y: 456,
        z: 789
    }
};

If you do a shallow copy of that object, then the x property of your new object is the same x object from the original:

var copy = $.extend( {}, obj );
copy.w = 321;
copy.x.y = 654;

Now your objects will look like this:

// copy looks as expected
var copy = {
    w: 321,
    x: {
        y: 654,
        z: 789
    }
};

// But changing copy.x.y also changed obj.x.y!
var obj = {
    w: 123,  // changing copy.w didn't affect obj.w
    x: {
        y: 654,  // changing copy.x.y also changed obj.x.y
        z: 789
    }
};

You can avoid this with a deep copy. The deep copy recurses into every nested object and array (and Date in Armand's code) to make copies of those objects in the same way it made a copy of the top-level object. So changing copy.x.y wouldn't affect obj.x.y.

Short answer: If in doubt, you probably want a deep copy.

I did a fun hack to solve this issue to my satisfaction. I've got an AJAX site that loads content dynamically, then modifies the window.location.hash, and I had code to run upon $(document).ready() to parse the hash and load the appropriate section. The thing is that I was perfectly happy with my section loading code for navigation, but wanted to add a way to intercept the browser back and forward buttons, which change the window location, but not interfere with my current page loading routines where I manipulate the window.location, and polling the window.location at constant intervals was out of the question.

What I ended up doing was creating an object as such:

var pageload = {
    ignorehashchange: false,
    loadUrl: function(){
        if (pageload.ignorehashchange == false){
            //code to parse window.location.hash and load content
        };
    }
};

Then, I added a line to my site script to run the pageload.loadUrl function upon the hashchange event, as such:

window.addEventListener("hashchange", pageload.loadUrl, false);

Then, any time I want to modify the window.location.hash without triggering this page loading routine, I simply add the following line before each window.location.hash = line:

pageload.ignorehashchange = true;

and then the following line after each hash modification line:

setTimeout(function(){pageload.ignorehashchange = false;}, 100);

So now my section loading routines are usually running, but if the user hits the 'back' or 'forward' buttons, the new location is parsed and the appropriate section loaded.

public int gcd(int num1, int num2) { 
    int max = Math.abs(num1);
    int min = Math.abs(num2);

    while (max > 0) {
        if (max < min) {
            int x = max;
            max = min;
            min = x;
        }
        max %= min;
    }

    return min;
}

This method uses the Euclid’s algorithm to get the "Greatest Common Divisor" of two integers. It receives two integers and returns the gcd of them. just that easy!

You can check it easily using Java.lang.Class.getSimpleName() Method Only if variable has non-primitive type. It doesnt work with primitive types int ,long etc.

reference - Here is the Oracle docs link

Your code was a bit mixed up. Here is a clean version:

<script type="text/javascript">
    $(document).ready(function() {
        $("#add").click(function() {
            $.post("SetAndGet.php", {
                know: $("#know").val()
            }, function(data) {
                $("#know_list").html(data);
            });
        });

        function countChar(val) {
            var len = val.value.length;
            if (len >= 500) {
                val.value = val.value.substring(0, 500);
            } else {
                $('#charNum').text(500 - len);
            }
        }
    });
</script>

If tomcat did not start up yet , you can use the command \bin\cataline version to check which JVM will the tomcat use when you start tomcat using bin\startup

In fact ,\bin\cataline version just call the main class of org.apache.catalina.util.ServerInfo , which is located inside the \lib\catalina.jar . The org.apache.catalina.util.ServerInfo gets the JVM Version and JVM Vendor by the following commands:

System.out.println("JVM Version: " +System.getProperty("java.runtime.version"));
System.out.println("JVM Vendor: " +System.getProperty("java.vm.vendor")); 

So , if the tomcat is running , you can create a JSP page that call org.apache.catalina.util.ServerInfo or just simply call the above System.getProperty() to get the JVM Version and Vendor . Deploy this JSP to the running tomcat instance and browse to it to see the result.

Alternatively, you should know which port is the running tomcat instance using . So , you can use the OS command to find which process is listening to this port. For example in the window , you can use the command netstat -aon to find out the process ID of a process that is listening to a particular port . Then go to the window task manager to check the full file path of this process ID belongs to. .The java version can then be determined from that file path.

Try this way:

select * from tab
where DateCol between DateAdd(DD,-7,GETDATE() ) and GETDATE() 

Hmm, best way is to use this command:

du -h -x / | sort -hr >> /home/log_size.txt

Then you will be able to get all sizes folders over all your server. Easy to help to you to find the biggest sizes.

I think the load event is right. What is not right is the way you use to retreive the content from iframe content dom.

What you need is the html of the page loaded in the iframe not the html of the iframe object.

What you have to do is to access the content document with iFrameObj.contentDocument. This returns the dom of the page loaded inside the iframe, if it is on the same domain of the current page.

I would retreive the content before removing the iframe.

I've tested in firefox and opera.

Then i think you can retreive your data with $(childDom).html() or $(childDom).find('some selector') ...

The whole ls -l and then cut is rather convoluted when you have stat. It is also vulnerable to the exact format of ls -l (it didn't work until I changed the column numbers for cut)

Also, fixed the useless use of cat.

<files.txt  xargs stat -c %s | paste -sd+ - | bc

Just use the format function

format(6, "08b")

The general form is

format(<the_integer>, "<0><width_of_string><format_specifier>")

I just do it like this:

CvCapture *capture = cvCreateFileCapture("rtsp://camera-address");

Also make sure this dll is available at runtime else cvCreateFileCapture will return NULL

opencv_ffmpeg200d.dll

The camera needs to allow unauthenticated access too, usually set via its web interface. MJPEG format worked via rtsp but MPEG4 didn't.

To go ahead and get a point out there, instead of repeatedly using these:

[A-Za-z0-9 _]
[A-Za-z0-9]

I have two (hopefully better) replacements for those two:

[\w ]
[^\W_]

The first one matches any word character (alphanumeric and _, as well as Unicode) and the space. The second matches anything that isn't a non-word character or an underscore (alphanumeric only, as well as Unicode).

If you don't want Unicode matching, then stick with the other answers. But these just look easier on the eyes (in my opinion). Taking the "preferred" answer as of this writing and using the shorter regexes gives us:

^[\w ]*[^\W_][\w ]*$

Perhaps more readable, perhaps less. Certainly shorter. Your choice.

EDIT:

Just as a note, I am assuming Perl-style regexes here. Your regex engine may or may not support things like \w and \W.

EDIT 2:

Tested mine with the JS regex tester that someone linked to and some basic examples worked fine. Didn't do anything extensive, just wanted to make sure that \w and \W worked fine in JS.

EDIT 3:

Having tried to test some Unicode with the JS regex tester site, I've discovered the problem: that page uses ISO instead of Unicode. No wonder my Japanese input didn't match. Oh well, that shouldn't be difficult to fix:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

Or so. I don't know what should be done as far as JavaScript, but I'm sure it's not hard.

This is a small example that will convert 'image.png' to 'image.jpg' at 70% image quality:

<?php
$image = imagecreatefrompng('image.png');
imagejpeg($image, 'image.jpg', 70);
imagedestroy($image);
?>

Hope that helps

A lot of these answers only accept single-character separators, or don't deal with edge cases well (e.g. empty separators), so I thought I would provide a more definitive solution.

Here are two functions, gsplit and split, adapted from the code in the Scribunto MediaWiki extension, which is used on wikis like Wikipedia. The code is licenced under the GPL v2. I have changed the variable names and added comments to make the code a bit easier to understand, and I have also changed the code to use regular Lua string patterns instead of Scribunto's patterns for Unicode strings. The original code has test cases here.

-- gsplit: iterate over substrings in a string separated by a pattern
-- 
-- Parameters:
-- text (string)    - the string to iterate over
-- pattern (string) - the separator pattern
-- plain (boolean)  - if true (or truthy), pattern is interpreted as a plain
--                    string, not a Lua pattern
-- 
-- Returns: iterator
--
-- Usage:
-- for substr in gsplit(text, pattern, plain) do
--   doSomething(substr)
-- end
local function gsplit(text, pattern, plain)
  local splitStart, length = 1, #text
  return function ()
    if splitStart then
      local sepStart, sepEnd = string.find(text, pattern, splitStart, plain)
      local ret
      if not sepStart then
        ret = string.sub(text, splitStart)
        splitStart = nil
      elseif sepEnd < sepStart then
        -- Empty separator!
        ret = string.sub(text, splitStart, sepStart)
        if sepStart < length then
          splitStart = sepStart + 1
        else
          splitStart = nil
        end
      else
        ret = sepStart > splitStart and string.sub(text, splitStart, sepStart - 1) or ''
        splitStart = sepEnd + 1
      end
      return ret
    end
  end
end

-- split: split a string into substrings separated by a pattern.
-- 
-- Parameters:
-- text (string)    - the string to iterate over
-- pattern (string) - the separator pattern
-- plain (boolean)  - if true (or truthy), pattern is interpreted as a plain
--                    string, not a Lua pattern
-- 
-- Returns: table (a sequence table containing the substrings)
local function split(text, pattern, plain)
  local ret = {}
  for match in gsplit(text, pattern, plain) do
    table.insert(ret, match)
  end
  return ret
end

Some examples of the split function in use:

local function printSequence(t)
  print(unpack(t))
end

printSequence(split('foo, bar,baz', ',%s*'))       -- foo     bar     baz
printSequence(split('foo, bar,baz', ',%s*', true)) -- foo, bar,baz
printSequence(split('foo', ''))                    -- f       o       o

And this option?

list_name<-list()
for(i in 1:100){
    paste("orca",i,sep="")->list_name[[i]]
}

It works perfectly. In the example you put, first line is missing, and then gives you the error message.

Simple Solution

radioSection.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
          @Override
          public void onCheckedChanged(RadioGroup group1, int checkedId1) {
              switch (checkedId1) {
                  case R.id.rbSr://radiobuttonID
                      //do what you want
                      break;
                  case R.id.rbJr://radiobuttonID
                      //do what you want
                      break;
              }
          }
      });

Hive Partitioning:

Partition divides large amount of data into multiple slices based on value of a table column(s).

Assume that you are storing information of people in entire world spread across 196+ countries spanning around 500 crores of entries. If you want to query people from a particular country (Vatican city), in absence of partitioning, you have to scan all 500 crores of entries even to fetch thousand entries of a country. If you partition the table based on country, you can fine tune querying process by just checking the data for only one country partition. Hive partition creates a separate directory for a column(s) value.

Pros:

1. Distribute execution load horizontally
2. Faster execution of queries in case of partition with low volume of data. e.g. Get the population from "Vatican city" returns very fast instead of searching entire population of world.

Cons:

1. Possibility of too many small partition creations - too many directories.
2. Effective for low volume data for a given partition. But some queries like group by on high volume of data still take long time to execute. e.g. Grouping of population of China will take long time compared to grouping of population in Vatican city. Partition is not solving responsiveness problem in case of data skewing towards a particular partition value.

Hive Bucketing:

Bucketing decomposes data into more manageable or equal parts.

With partitioning, there is a possibility that you can create multiple small partitions based on column values. If you go for bucketing, you are restricting number of buckets to store the data. This number is defined during table creation scripts.

Pros

1. Due to equal volumes of data in each partition, joins at Map side will be quicker.
2. Faster query response like partitioning

Cons

1. You can define number of buckets during table creation but loading of equal volume of data has to be done manually by programmers.

I recently just ran into this issue as well. I had a very large table in the dialog div. It was >15,000 rows. When the .empty() was called on the dialog div, I was getting the error above.

I found a round-about solution where before I call cleaning the dialog box, I would remove every other row from the very large table, then call the .empty(). It seemed to have worked though. It seems that my old version of JQuery can't handle such large elements.

Detecting CSS 3D transforms

Modernizr can detect CSS 3D transforms, yeah. The truthiness of Modernizr.csstransforms3d will tell you if the browser supports them.

The above link lets you select which tests to include in a Modernizr build, and the option you're looking for is available there.

Detecting IE specifically

Alternatively, as user356990 answered, you can use conditional comments if you're searching for IE and IE alone. Rather than creating a global variable, you can use HTML5 Boilerplate's <html> conditional comments trick to assign a class:

<!--[if lt IE 7]>      <html class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]>         <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]>         <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js"> <!--<![endif]-->

If you already have jQuery initialised, you can just check with $('html').hasClass('lt-ie9'). If you need to check which IE version you're in so you can conditionally load either jQuery 1.x or 2.x, you can do something like this:

myChecks.ltIE9 = (function(){
    var htmlElemClasses = document.querySelector('html').className.split(' ');
    if (!htmlElemClasses){return false;}
    for (var i = 0; i < htmlElemClasses.length; i += 1 ){
      var klass = htmlElemClasses[i];
      if (klass === 'lt-ie9'){
        return true;
      }
    }
    return false;
}());

N.B. IE conditional comments are only supported up to IE9 inclusive. From IE10 onwards, Microsoft encourages using feature detection rather than browser detection.

Whichever method you choose, you'd then test with

if ( myChecks.ltIE9 || Modernizr.csstransforms3d ){
    // iframe or flash fallback
} 

Don't take that || literally, of course.

Surprising solution -
adding following property to the applied selectors:

selector {
    text-shadow: 0 0 0;
}

Actually, result is the same just with text-shadow: 0 0;, but I like to explicitly set blur-radius.

It's not an universal solution, but might help in some cases. Moreover I haven't experienced (also not thoroughly tested) negative performance impacts of this solution so far.

Use INDIRECT()

=SUM(INDIRECT(<start cell here> & ":" & <end cell here>))

Here is what i did for logback.

I created a TestAppender class:

public class TestAppender extends AppenderBase<ILoggingEvent> {

    private Stack<ILoggingEvent> events = new Stack<ILoggingEvent>();

    @Override
    protected void append(ILoggingEvent event) {
        events.add(event);
    }

    public void clear() {
        events.clear();
    }

    public ILoggingEvent getLastEvent() {
        return events.pop();
    }
}

Then in the parent of my testng unit test class I created a method:

protected TestAppender testAppender;

@BeforeClass
public void setupLogsForTesting() {
    Logger root = (Logger)LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
    testAppender = (TestAppender)root.getAppender("TEST");
    if (testAppender != null) {
        testAppender.clear();
    }
}

I have a logback-test.xml file defined in src/test/resources and I added a test appender:

<appender name="TEST" class="com.intuit.icn.TestAppender">
    <encoder>
        <pattern>%m%n</pattern>
    </encoder>
</appender>

and added this appender to the root appender:

<root>
    <level value="error" />
    <appender-ref ref="STDOUT" />
    <appender-ref ref="TEST" />
</root>

Now in my test classes that extend from my parent test class I can get the appender and get the last message logged and verify the message, the level, the throwable.

ILoggingEvent lastEvent = testAppender.getLastEvent();
assertEquals(lastEvent.getMessage(), "...");
assertEquals(lastEvent.getLevel(), Level.WARN);
assertEquals(lastEvent.getThrowableProxy().getMessage(), "...");

if you have repository for entity Foo and need to select all entries with exact string value boo (also works for other primitive types or entity types). Put this into your repository interface:

List<Foo> findByBoo(String boo);

if you need to order results:

List<Foo> findByBooOrderById(String boo);

See more at reference.

use the command

wget -m www.ilanni.com/nexus/content/

Here is an example of decoding a generic map using both switch and reflection, so if you don't match the type, use reflection to figure it out and then add the type in next time.

var data map[string]interface {}

...

for k, v := range data {
    fmt.Printf("pair:%s\t%s\n", k, v)   

    switch t := v.(type) {
    case int:
        fmt.Printf("Integer: %v\n", t)
    case float64:
        fmt.Printf("Float64: %v\n", t)
    case string:
        fmt.Printf("String: %v\n", t)
    case bool:
        fmt.Printf("Bool: %v\n", t)
    case []interface {}:
        for i,n := range t {
            fmt.Printf("Item: %v= %v\n", i, n)
        }
    default:
        var r = reflect.TypeOf(t)
        fmt.Printf("Other:%v\n", r)             
    }
}

Like what Amber says in her answer: create a function. In fact when you don't have to make classes if you have something like:

class Person(object):
    def __init__(self, arg1, arg2):
        self.arg1 = arg1
        self.arg2 = arg2

    def compute(self, other):
        """ Example of bad class design, don't care about the result """
        return self.arg1 + self.arg2 % other

Here you just have a function encapsulate in a class. This just make the code less readable and less efficient. In fact the function compute can be written just like this:

def compute(arg1, arg2, other):
     return arg1 + arg2 % other

You should use classes only if you have more than 1 function to it and if keep a internal state (with attributes) has sense. Otherwise, if you want to regroup functions, just create a module in a new .py file.

You might look this video (Youtube, about 30min), which explains my point. Jack Diederich shows why classes are evil in that case and why it's such a bad design, especially in things like API.
It's quite a long video but it's a must see.

I'd like to expand a little bit on Pavel Minaev's answer, which you should read before reading my answer. Both solutions presented by Pavel won't compile if the member to be compared (such as id in the question's code) is private. In this case, VS2013 throws the following error for me:

error C2248: 'Class1::id' : cannot access private member declared in class 'Class1'

As mentioned by SkyWalker in the comments on Pavel's answer, using a friend declaration helps. If you wonder about the correct syntax, here it is:

class Class1
{
public:
    Class1(int id) : id(id) {}

private:
    int id;
    friend struct Class1Compare;      // Use this for Pavel's first solution.
    friend struct std::less<Class1>;  // Use this for Pavel's second solution.
};

Code on Ideone

However, if you have an access function for your private member, for example getId() for id, as follows:

class Class1
{
public:
    Class1(int id) : id(id) {}
    int getId() const { return id; }

private:
    int id;
};

then you can use it instead of a friend declaration (i.e. you compare lhs.getId() < rhs.getId()). Since C++11, you can also use a lambda expression for Pavel's first solution instead of defining a comparator function object class. Putting everything together, the code could be writtem as follows:

auto comp = [](const Class1& lhs, const Class1& rhs){ return lhs.getId() < rhs.getId(); };
std::map<Class1, int, decltype(comp)> c2int(comp);

Code on Ideone

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

You could also use lattice::histogram()

You say you're using:

time.asctime(time.localtime(date_in_seconds_from_bash))

where date_in_seconds_from_bash is presumably the output of date +%s.

The time.localtime function, as the name implies, gives you local time.

If you want UTC, use time.gmtime() rather than time.localtime().

As JamesNoonan33's answer says, the output of date +%s is timezone invariant, so date +%s is exactly equivalent to date -u %s. It prints the number of seconds since the "epoch", which is 1970-01-01 00:00:00 UTC. The output you show in your question is entirely consistent with that:

date -u
Thu Jul 3 07:28:20 UTC 2014

date +%s
1404372514   # 14 seconds after "date -u" command

date -u +%s
1404372515   # 15 seconds after "date -u" command

I found the solution to my problem. In my ~/.bashrc:

export PATH=${PATH}:/path/to/android-sdk/tools

However adb is not located in the android-sdk/tools/, rather in android-sdk/platform-tools/. So I added the following

export PATH=${PATH}:/path/to/android-sdk/tools:/path/to/android-sdk/platform-tools

And that solved the problem for me.

All you need to do is change the string within the java.text.SimpleDateFormat constructor to: "MM-dd-yyyy HH:mm:ss".

Just use the appropriate letters to build the above string to match your input date.

In addition to Norman Ramsey's answer, I'd like to add that you can double-quote the entire string (which may make the statement more readable and less error prone).

So if you want to search for 'foo' and replace it with the content of $BAR, you can enclose the sed command in double-quotes.

sed 's/foo/$BAR/g'
sed "s/foo/$BAR/g"

In the first, $BAR will not expand correctly while in the second $BAR will expand correctly.

you can use the following to find the posted data.

data = json.loads(request.raw_post_data)

There is one other thing you might want to think about, Currently it can only add the warning class if it is empty, how about removing the class again when the form is not empty anymore.

like this:

$('#apply-form input').blur(function()
{
    if( !$(this).val() ) {
          $(this).parents('p').addClass('warning');
    } else if ($(this).val()) {
          $(this).parents('p').removeClass('warning');
    }
});

ONELINER:

var min= dates.sort((a,b)=>a-b)[0], max= dates.slice(-1)[0];

result in variables min and max, complexity O(nlogn), editable example here. If your array has no-date values (like null) first clean it by dates=dates.filter(d=> d instanceof Date);.

var dates = [];_x000D_
dates.push(new Date("2011-06-25")); // I change "/" to "-" in "2011/06/25"_x000D_
dates.push(new Date("2011-06-26")); // because conosle log write dates _x000D_
dates.push(new Date("2011-06-27")); // using "-"._x000D_
dates.push(new Date("2011-06-28"));_x000D_
_x000D_
var min= dates.sort((a,b)=>a-b)[0], max= dates.slice(-1)[0];_x000D_
_x000D_
console.log({min,max});

Here my solution without going backward and without a temporary list

while (listBox1.Items.Count > 0)
{
  string s = listBox1.Items[0] as string;
  // do something with s
  listBox1.Items.RemoveAt(0);
}

Just another hack can be like this.

I have Array of strings which I need to concatenate. So I added that array into dictionary and then used it inside for loop which worked.

{% set dict1 = {'e':''} %}
{% for i in list1 %}
{% if dict1.update({'e':dict1.e+":"+i+"/"+i}) %} {% endif %}
{% endfor %}
{% set layer_string = dict1['e'] %}

It should just be

name[0].firstChild.nodeValue

For latest laravel version also check your version because I was also facing this error but after update latest php version, I got rid from this error.

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

Below are two solutions to select the range A1.

Cells(1,1).Select '(row 1, column 1) 
Range("A1").Select

Also check out this link;

• http://www.excel-vba.com/vba-code-2-6-cells-ranges.htm

We strongly recommend that you use Range instead of Cells to work with cells and groups of cells. It makes your sentences much clearer and you are not forced to remember that column AE is column 31.

The only time that you will use Cells is when you want to select all the cells of a worksheet. For example: Cells.Select To select all cells and then empty all cells of values or formulas you will use: Cells.ClearContents

--

"Cells" is particularly useful when setting ranges dynamically and looping through ranges by using counters. Defining ranges using letters as column numbers may be more transparent on the short run, but it will also make your application more rigid since they are "hard coded" representations - not dynamic.

In SQL Server Management Studio of Any Version, Use BIT as Data Type

which will provide you with True or False Value options. in case you want to use Only 1 or 0 then you can use this method:

CREATE TABLE SampleBit(
    bar int NOT NULL CONSTRAINT CK_foo_bar CHECK (bar IN (-1, 0, 1))
)

But I will strictly advise BIT as The BEST Option. Hope fully it's help someone.

Open SQL Management Studio Express and log in to the server to which you want to attach the database. In the 'Object Explorer' window, right-click on the 'Databases' folder and select 'Attach...' The 'Attach Databases' window will open; inside that window click 'Add...' and then navigate to your .MDF file and click 'OK'. Click 'OK' once more to finish attaching the database and you are done. The database should be available for use. best regards :)

add #include <iostream> to the start of io.cpp too.

First is latitude, second longitude. Different than many constructors in mapbox.

Here are examples of formats that work:

• Degrees, minutes, and seconds (DMS): 41°24'12.2"N 2°10'26.5"E
• Degrees and decimal minutes (DMM): 41 24.2028, 2 10.4418
• Decimal degrees (DD): 41.40338, 2.17403

Tips for formatting your coordinates

• Use the degree symbol instead of “d”.
• Use periods as decimals, not commas.
  • Incorrect: 41,40338, 2,17403.
  • Correct: 41.40338, 2.17403.
• List your latitude coordinates before longitude coordinates.
• Check that the first number in your latitude coordinate is between -90 and 90 and the first number in your longitude coordinate is between -180 and 180.

I upgraded VS2017 from version 15.2 to 15.8. With version 15.8 here's what happened:

Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0 no longer worked for me! I had to change it to 10.0.17134.0 and then everything built again. After the upgrade and without making this change, I was getting the same header file errors.

I would have submitted this as a comment on one of the other answers but I don't have enough reputation yet.

The sample above worked like a charm. I just did a modification just in case I need to manage multiple values. I hope this helps!

app.service('sharedProperties', function () {

    var hashtable = {};

    return {
        setValue: function (key, value) {
            hashtable[key] = value;
        },
        getValue: function (key) {
            return hashtable[key];
        }
    }
});

This library supports HTML5 postMessage and legacy browsers with resize+hash https://github.com/ternarylabs/porthole

Edit: Now in 2014, IE6/7 usage is quite low, IE8 and above all support postMessage so I now suggest to just use that.

....but $('span', $('#foo')); doesn't work?

This method is called as providing selector context.

In this you provide a second argument to the jQuery selector. It can be any css object string just like you would pass for direct selecting or a jQuery element.

eg.

$("span",".cont1").css("background", '#F00');

The above line will select all spans within the container having the class named cont1.

Ok so I was having this issue where I tried several different options.

The font i'm using is Ubuntu-LI , I created a font folder in my working directory. under the folder fonts

I was able to apply it... eventually here is my working code

I wanted this to apply to my entire website so I put it at the top of the css doc. above all of the Div tags (not that it matters, just know that any individual fonts you assign post your script will take precedence)

@font-face{
    font-family: "Ubuntu-LI";
    src: url("/fonts/Ubuntu/(Ubuntu-LI.ttf"),
    url("../fonts/Ubuntu/Ubuntu-LI.ttf");
}

*{
    font-family:"Ubuntu-LI";
}

If i then wanted all of my H1 tags to be something else lets say sans sarif I would do something like

h1{
   font-family: Sans-sarif;
}

From which case only my H1 tags would be the sans-sarif font and the rest of my page would be the Ubuntu-LI font

As mentioned by @physicsGuy above, You can use the hinterland extension. Simple steps to do it.

Installing nbextension using conda forge channel. Simply run the below command in conda terminal:

conda install -c conda-forge jupyter_nbextensions_configurator

Next Step enabling the hinterland extension. Run the below command in conda terminal:

jupyter nbextension enable hinterland/hinterland

That's it, done.

Try this , if you are using PHP 5.3+, in php

$query_date = '2010-02-04';
$date = new DateTime($query_date);
//First day of month
$date->modify('first day of this month');
$firstday= $date->format('Y-m-d');
//Last day of month
$date->modify('last day of this month');
$lastday= $date->format('Y-m-d');

For finding next month last date, modify as follows,

 $date->modify('last day of 1 month');
 echo $date->format('Y-m-d');

and so on..

The answer actually depends on your specific requirements.

For instance, do you need to protect your web messages or confidentiality is not required and all you need is to authenticate end parties and ensure message integrity? If this is the case - and it often is with web services - HTTPS is probably the wrong hammer.

However - from my experience - do not overlook the complexity of the system you're building. Not only HTTPS is easier to deploy correctly, but an application that relies on the transport layer security is easier to debug (over plain HTTP).

Good luck.

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

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

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

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

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

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

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

Here is the documentation. That should tell you what it means and what to do with them. You should avoid using the numeric value and use the constants listed there as well, as the number may change between different systems.

It is better to use DataView for this task.

Example of the using it you can find in this post: How to filter data in dataview

Use :set nowrap .. works like a charm!

I have this hunk in my .gitconfig and it seems to work fine (disabled for both diff and show):

[pager]
    diff = false
    show = false

That's because you are dealing with floating point numbers. Division by zero returns Infinity, which is similar to NaN (not a number).

If you want to prevent this, you have to test tab[i] before using it. Then you can throw your own exception, if you really need it.

There are some different way to do that

sass --watch --style=compressed main.scss main.css

or

sass --watch a.scss:a.css --style compressed

or

By Using visual studio code extension live sass compiler

You should give the new monkeyrunner a go. Maybe this can solve your problems. You put keycodes in it for testing, maybe touch events are also possible.

I have the same issue when using Visual Studio 2012. By turn on the IIS feature just not working, because I still received the error. Try the method but no lucky.

My solution is:

• Download the hotfix.
• At the command line, Restart IIS by typing iisreset /noforce YourComputerName, and press ENTER.

Use serialize and deserialize methods in SerializationUtils from commons-lang.

After handling with this error too, I can support this list of answers with my own case.

It's at the same time simple and dumb (maybe not dumb for beginners like me, but yes for experts), the script reference to angular.min.js must be the first one in your list of scripts in the html page.

This works:

<script src="Scripts/angular.min.js"></script>
<script src="MyScripts/MyCartController.js"></script>
<script src="MyScripts/MyShoppingModule.js"></script>

This not:

<script src="MyScripts/MyCartController.js"></script>
<script src="MyScripts/MyShoppingModule.js"></script>
<script src="Scripts/angular.min.js"></script>

Notice about the angular.min.js.

Hope it helps anyone !! :)

Here you can benchmark all supported hashes on your hardware, supported by your version of node.js. Some are cryptographic, and some is just for a checksum. Its calculating "Hello World" 1 million times for each algorithm. It may take around 1-15 seconds for each algorithm (Tested on the Standard Google Computing Engine with Node.js 4.2.2).

for(var i1=0;i1<crypto.getHashes().length;i1++){
  var Algh=crypto.getHashes()[i1];
  console.time(Algh);
  for(var i2=0;i2<1000000;i2++){
    crypto.createHash(Algh).update("Hello World").digest("hex");
  }
  console.timeEnd(Algh);  
}

Note that there's no general solution to this. An XSD can easily describe something that does not map to a relational database.

While you can try to "automate" this, your XSD's must be designed with a relational database in mind, or it won't work out well.

If the XSD's have features that don't map well you'll have to (1) design a mapping of some kind and then (2) write your own application to translate the XSD's into DDL.

Been there, done that. Work for hire -- no open source available.

I just encountered this problem, and it turned out to be that my project is stored in my user folder, which is stored on the network, and we had a momentary network outage. I did a build; it complained that my files had been modified outside the editor (they hadn't; the file locks just got borked), and it built fine, removing the error regarding the InitializeComponent() method.

BTW, in case you're wondering, developing something from a network drive is bad practice. It becomes particularly problematic when you're trying to leverage .NET's managed code; in my experience, it freaks out every time you build. I forgot to put this little throw-away project in the proper folder, and ended up paying the price.

Hmmm. There was an answer with a list comprehension here, but it's disappeared.

Here:

 [i for i,x in enumerate(testlist) if x == 1]

Example:

>>> testlist
[1, 2, 3, 5, 3, 1, 2, 1, 6]
>>> [i for i,x in enumerate(testlist) if x == 1]
[0, 5, 7]

Update:

Okay, you want a generator expression, we'll have a generator expression. Here's the list comprehension again, in a for loop:

>>> for i in [i for i,x in enumerate(testlist) if x == 1]:
...     print i
... 
0
5
7

Now we'll construct a generator...

>>> (i for i,x in enumerate(testlist) if x == 1)
<generator object at 0x6b508>
>>> for i in (i for i,x in enumerate(testlist) if x == 1):
...     print i
... 
0
5
7

and niftily enough, we can assign that to a variable, and use it from there...

>>> gen = (i for i,x in enumerate(testlist) if x == 1)
>>> for i in gen: print i
... 
0
5
7

And to think I used to write FORTRAN.

One other significant point if you're using C# 6:

'=>' can be used instead of 'get' and is only for 'get only' methods - it can't be used with a 'set'.

For C# 7, see the comment from @avenmore below - it can now be used in more places. Here's a good reference - https://csharp.christiannagel.com/2017/01/25/expressionbodiedmembers/

PrincipalContext for browsing the AD is ridiculously slow (only use it for .ValidateCredentials, see below), use DirectoryEntry instead and .PropertiesToLoad() so you only pay for what you need.

Filters and syntax here: https://social.technet.microsoft.com/wiki/contents/articles/5392.active-directory-ldap-syntax-filters.aspx

Attributes here: https://docs.microsoft.com/en-us/windows/win32/adschema/attributes-all

using (var root = new DirectoryEntry($"LDAP://{Domain}"))
{
    using (var searcher = new DirectorySearcher(root))
    {
        // looking for a specific user
        searcher.Filter = $"(&(objectCategory=person)(objectClass=user)(sAMAccountName={username}))";
        // I only care about what groups the user is a memberOf
        searcher.PropertiesToLoad.Add("memberOf");

        // FYI, non-null results means the user was found
        var results = searcher.FindOne();

        var properties = results?.Properties;
        if (properties?.Contains("memberOf") == true)
        {
            // ... iterate over all the groups the user is a member of
        }
    }
}

Clean, simple, fast. No magic, no half-documented calls to .RefreshCache to grab the tokenGroups or to .Bind or .NativeObject in a try/catch to validate credentials.

For authenticating the user:

using (var context = new PrincipalContext(ContextType.Domain))
{
    return context.ValidateCredentials(username, password);
}

There is a clear distinction between the usage of ' ' and " ".

When ' ' is used around anything, there is no "transformation or translation" done. It is printed as it is.

With " ", whatever it surrounds, is "translated or transformed" into its value.

By translation/ transformation I mean the following: Anything within the single quotes will not be "translated" to their values. They will be taken as they are inside quotes. Example: a=23, then echo '$a' will produce $a on standard output. Whereas echo "$a" will produce 23 on standard output.

Has anyone thought about that wamp server default not include the httpd-vhosts.conf file. My approach is to remove the note below

 conf
  # Virtual hosts
  Include conf/extra/httpd-vhosts.conf

in httpd.conf file. That is all.

I'm just a newbie here so maybe it's pure luck if I found this :

After trying to run a script from the interpreter prompt >>> with the command

    execfile('filename.py')

for which I got a "NameError: name 'execfile' is not defined" I tried a very basic

    import filename

it worked well :-)

I hope this can be helpful and thank you all for the great hints, examples and all those masterly commented pieces of code that are a great inspiration for newcomers !

I use Ubuntu 16.014 LTS x64. Python 3.5.2 (default, Nov 17 2016, 17:05:23) [GCC 5.4.0 20160609] on linux

Replace the desired hyphen with an underscore; it will automatically be rendered as a hyphen:

@Html.ActionLink("Edit", "edit", "markets",
    new { id = 1 },
    new {@class="ui-btn-right", data_icon="gear"})

becomes:

<form action="markets/Edit/1" class="ui-btn-right" data-icon="gear" .../>

I have the same problem, and i realize that. When we create adapter and set it to listview, listview will point to object somewhere in memory which adapter hold, data in this object will show in listview.

adapter = new CustomAdapter(data);
listview.setadapter(adapter);

if we create an object for adapter with another data again and notifydatasetchanged():

adapter = new CustomAdapter(anotherdata);
adapter.notifyDataSetChanged();

this will do not affect to data in listview because the list is pointing to different object, this object does not know anything about new object in adapter, and notifyDataSetChanged() affect nothing. So we should change data in object and avoid to create a new object again for adapter

For the less specific case (not just the code in the question - since this is one of the first results in Google for this generic error message. This error also occurs when running certain os command with None argument.

For example:

os.path.exists(arg)  
os.stat(arg)

Will raise this exception when arg is None.

Hey I had the same problem. I tried to convert '2017-02-20 12:15:32' varchar to a date with TO_DATE('2017-02-20 12:15:32','YYYY-MM-DD HH24:MI:SS') and all I received was 2017-02-20 the time disappeared

My solution was to use TO_TIMESTAMP('2017-02-20 12:15:32','YYYY-MM-DD HH24:MI:SS') now the time doesn't disappear.

This should give you the result you want.

double total = 0;
int number = 0;
float percentage = number / total * 100
printf("%.2f",percentage);

Note that the first operand is a double

It is simple with JavaScript and PHP:

Even though the user can mess with his/her internal clock and/or timezone, the best way I found so far, to get the offset, remains new Date().getTimezoneOffset();. It's non-invasive, doesn't give head-aches and eliminates the need to rely on third parties.

Say I have a table, users, that contains a field date_created int(13), for storing Unix timestamps;

Assuming a client creates a new account, data is received by post, and I need to insert/update the date_created column with the client's Unix timestamp, not the server's.

Since the timezoneOffset is needed at the time of insert/update, it is passed as an extra $_POST element when the client submits the form, thus eliminating the need to store it in sessions and/or cookies, and no additional server hits either.

var off = (-new Date().getTimezoneOffset()/60).toString();//note the '-' in front which makes it return positive for negative offsets and negative for positive offsets
var tzo = off == '0' ? 'GMT' : off.indexOf('-') > -1 ? 'GMT'+off : 'GMT+'+off;

Say the server receives tzo as $_POST['tzo'];

$ts = new DateTime('now', new DateTimeZone($_POST['tzo']);
$user_time = $ts->format("F j, Y, g:i a");//will return the users current time in readable format, regardless of whether date_default_timezone() is set or not.
$user_timestamp = strtotime($user_time);

Insert/update date_created=$user_timestamp.

When retrieving the date_created, you can convert the timestamp like so:

$date_created = // Get from the database
$created = date("F j, Y, g:i a",$date_created); // Return it to the user or whatever

Now, this example may fit one's needs, when it comes to inserting a first timestamp... When it comes to an additional timestamp, or table, you may want to consider inserting the tzo value into the users table for future reference, or setting it as session or as a cookie.

P.S. BUT what if the user travels and switches timezones. Logs in at GMT+4, travels fast to GMT-1 and logs in again. Last login would be in the future.

I think... we think too much.

According to the select_list Oracle select documentation the AS is optional.

As a personal note I think it is easier to read with the AS

Try this :

function missingCharacter($list) {

        // Create an array with a range from array minimum to maximu
        $newArray = range(min($list), max($list));

        // Find those elements that are present in the $newArray but not in given $list
        return array_diff($newArray, $list);
    }
print_r(missCharacter(array('a','b','d','g')));

Warning by @Geoff: see my note below, only one of the suggestions in this answer works (though on both columns).

I would use sed:

sed 's/, /,/' input.txt

This will remove on leading space after the , . Output:

Name,Order
Trim,working
cat,cat1

More general might be the following, it will remove possibly multiple spaces and/or tabs after the ,:

sed 's/,[ \t]\?/,/g' input.txt

It will also work with more than two columns because of the global modifier /g

@Floris asked in discussion for a solution that removes trailing and and ending whitespaces in each colum (even the first and last) while not removing white spaces in the middle of a column:

sed 's/[ \t]\?,[ \t]\?/,/g; s/^[ \t]\+//g; s/[ \t]\+$//g' input.txt

*EDIT by @Geoff, I've appended the input file name to this one, and now it only removes all leading & trailing spaces (though from both columns). The other suggestions within this answer don't work. But try: " Multiple spaces , and 2 spaces before here " *

IMO sed is the optimal tool for this job. However, here comes a solution with awk because you've asked for that:

awk -F', ' '{printf "%s,%s\n", $1, $2}' input.txt

Another simple solution that comes in mind to remove all whitespaces is tr -d:

cat input.txt | tr -d ' '

In Ubuntu, you can simply install Open JDK by following commands.

sudo apt-get update    
sudo apt-get install default-jdk

You can check the java version by following the command.

java -version

If you want to install Oracle JDK 8 follow the below commands.

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

If you want to switch java versions you can try below methods.

vi ~/.bashrc and add the following line export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_221 (path/jdk folder)

or

sudo vi /etc/profile and add the following lines

#JAVA_HOME=/usr/lib/jvm/jdk1.8.0_221
JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME
export JRE_HOME
export PATH

You can comment on the other version. This needs to sign out and sign back in to use. If you want to try it on the go you can type the below command in the same terminal. It'll only update the java version for a particular terminal.

source /etc/profile

You can always check the java version by java -version command.

Here is my sort array function in the utils library:

sortArray: function(array) {
    array.sort(function(a, b) {
        return a > b;
    });
},

# Let's test a string array
var arr = ['bbc', 'chrome', 'aux', 'ext', 'dog'];
utils.sortArray(arr);
console.log(arr);
>>> ["aux", "bbc", "chrome", "dog", "ext", remove: function]

# Let's test a number array
var arr = [55, 22, 1425, 12, 78];
utils.sortArray(arr);
console.log(arr);
>>> [12, 22, 55, 78, 1425, remove: function]

I came across a similar situation after publishing a ClickOnce application, and one of my colleagues on a different domain reported that it fails to launch.

To find out what was going on, I added a try catch statement inside the MainWindow method as @BradleyDotNET mentioned in one comment on the original post, and then published again.

public MainWindow()
{
    try
    {
        InitializeComponent();
    }
    catch (Exception exc)
    {
        MessageBox.Show(exc.ToString());
    }
}

Then my colleague reported to me the exception detail, and it was a missing reference of a third party framework dll file.

Added the reference and problem solved.

Try this

ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable("COLOR"));

Look into composite formatting:

Console.WriteLine("{0}.{1}.{2}", mon, da, yer);

You could also write (although it's not really recommended):

Console.WriteLine(mon + "." + da + "." + yer);

And, with the release of C# 6.0, you have string interpolation expressions:

Console.WriteLine($"{mon}.{da}.{yer}");  // note the $ prefix.

I just added a padding-top to the div below the nav. Hope it helps. I'm new on this. C:

#nav {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    margin: 0 auto;
    padding: 0;
    background: url(../css/patterns/black_denim.png);
    z-index: 9999;
}

#container {
    display: block;
    padding: 6em 0 3em;
}

simple load xml file ..

$xml = @simplexml_load_string($retValuet);

$status = (string)$xml->Status; 
$operator_trans_id = (string)$xml->OPID;
$trns_id = (string)$xml->TID;

?>

I had a similar problem to yours on windows as the following.

D:\ProgramFiles\Android> adb pull /data/local/tmp/com.packagename_dumped_1766.dex D:\ProgramFiles\Android\com.packagename_dumped_1766.dex
adb: error: failed to copy '/data/local/tmp/com.packagename_dumped_1766.dex' to 'D:\ProgramFiles\Android\com.packagename_dumped_1766.dex': remote Permission denied

My solution:

At first I also made an attempt to use cat as ansi_lumen answered, but I got into trouble about CR and LR (\r\n) characters. And then I just had to change those file permisions by chmod and pulled again to this problem was solved without introducing other problems. After that, may we need to restore their original permissions as Goran Devs answered.

So just pay a little attention.

TL;DR

My story:

Firstly, I used the cat to download all files from android to my windows,

@echo off
cd /d %~dp0
:: %~dp0 = D:\ProgramFiles\Android\
SET ThisBatDir=%~dp0
:: adb shell ls /data/local/tmp/com.packagename_dumped_* > %~dp0\dump_file_list.txt
FOR /f "delims=" %%a in ('adb shell ls /data/local/tmp/com.packagename_dumped_*') do call :processline %%a %%~nxa

goto :eof

:: https://stackoverflow.com/questions/232651/why-the-system-cannot-find-the-batch-label-specified-is-thrown-even-if-label-e
:processline
SET RemoteFullPath=%1
set FileName=%2
:: echo "%RemoteFullPath%|%ThisBatDir%|%FileName%"
call adb shell su -c cat %RemoteFullPath% > %ThisBatDir%%FileName%
goto :eof

:eof

However, those downloaded dex files were broken because of CR and LR (\r\n) characters on windows. We can use hexdump to inspect its content in Hex+ASCII form (or Notepad++ with "View > Show Symbol > Show All Characters" checked). Note, the 5th and 6th byte (0d 0a)).

So I first viewed its file permision,

then, changed its permision,

D:\ProgramFiles\Android> adb shell su -c chmod 777 /data/local/tmp/com.packagename_dumped_*

D:\ProgramFiles\Android> adb shell ls -l /data/local/tmp
-rwxrwxrwx root     root        57344 2020-03-28 17:45 com.packagename_dumped_1766.dex

As a result, I made it.

D:\ProgramFiles\Android> adb pull /data/local/tmp/com.packagename_dumped_1766.dex D:\ProgramFiles\Android\com.packagename_dumped_1766.dex
/data/local/tmp/com.packagename_dumped_1766.de... 1 file pulled, 0 skipped. 3.6 MB/s (57344 bytes in 0.015s)

Now, jadx-gui-dev.exe or sh d2j-dex2jar.sh -f ~/path/to/apk_to_decompile.apk could properly enjoy them.

Its very simple. Just create a View with the black background color.

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="#000"/>

This will create a horizontal line with background color. You can also add other attributes such as margins, paddings etc just like any other view.

Try setting the style to display=none:

<img src="a.gif" style="display:none">

Mockito allows mocking abstract classes by means of the @Mock annotation:

public abstract class My {

    public abstract boolean myAbstractMethod();

    public void myNonAbstractMethod() {
        // ...
    }
}

@RunWith(MockitoJUnitRunner.class)
public class MyTest {

    @Mock(answer = Answers.CALLS_REAL_METHODS)
    private My my;

    @Test
    private void shouldPass() {
        BDDMockito.given(my.myAbstractMethod()).willReturn(true);
        my.myNonAbstractMethod();
        // ...
    }
}

The disadvantage is that it cannot be used if you need constructor parameters.

Add the following JARs to the build path or lib folder of the project:

1. slf4j-api-1.7.2.jar
2. slf4j-jdk14-1.7.2.jar

If as me you've tried everything above (especially windows 10 users ) and nothing helped here is what eventually solved the issue. The solution was ridiculously easy but took a day to figure it out.

1. Recommended to remove host only network adapter from virtual box, to do that open virtual box File->Preferences->Network->select tab host only network adapter->remove all (no worries when you start a vm from genymotion it will create new). Now open Genymotion and try to start your virtual device. Get the error ? that's good follow second step
2. (What actually fixed the issue) Go to Control Panel->Network and Internet->Network Connections, on there you should see an Ethernet network adapter that virtual box created ( it was created automatically when you started device from genymotion), so right click on it then Properties then CHECK VirtualBox NDIS6 Bridged Networking Driver, see image attached.
3. You're done. Start your device from genymotion, should work now.

leave only one entry for your host IP in /etc/hosts file, it resolved.

The spring configuration precedence is as follows.

1. ServletConfig init Parameter
2. ServletContext init parameter
3. JNDI attributes
4. System.getProperties()

So your configuration will be overridden at the command-line if you wish to do that. But the recommendation is to avoid overriding, though you can use multiple profiles.

Use the START command:

start [programPath]

If the path to the program contains spaces remember to add quotes. In this case you also need to provide a title for the opening console window

start "[title]" "[program path]"

If you need to provide arguments append them at the end (outside the command quotes)

start "[title]" "[program path]" [list of command args]

Use the /b option to avoid opening a new console window (but in that case you cannot interrupt the application using CTRL-C

The solution is somewhat simple; once you have deleted the row from the datagrid (Your code ONLY removes the row from the grid and NOT the datasource) then you do not need to do anything else. As you are doing a databind operation immediately after, without updating the datasource, you are re-adding all the rows from the source to the gridview control (including the row removed from the grid in the previous statement).

To simply delete from the grid without a datasource then just call the delete operation on the grid and that is all you need to do... no databinding is needed after that.

It's due to operator precidence. Try changing it to:

while(($file = readdir($handle)) !== FALSE)
{
    $results_array[] = $file;
}
closedir($handle);

Maybe this answer will help:

nginx error connect to php5-fpm.sock failed (13: Permission denied)

The solution was to replace www-data with nginx in /var/www/php/fpm/pool.d/www.conf

And respectively modify the socket credentials:

$ sudo chmod nginx:nginx /var/run/php/php7.2-fpm.sock

You can create a class that is passed a reference to the parent JFrame and holds it in a JFrame variable. Then you can lock the frame that created your new frame.

parentFrame.disable();

//Some actions

parentFrame.enable();

I shared my experience of using two LEFT JOINS in a single SQL query.

I have 3 tables:

Table 1) Patient consists columns PatientID, PatientName

Table 2) Appointment consists columns AppointmentID, AppointmentDateTime, PatientID, DoctorID

Table 3) Doctor consists columns DoctorID, DoctorName

Query:

SELECT Patient.patientname, AppointmentDateTime, Doctor.doctorname

FROM Appointment 

LEFT JOIN Doctor ON Appointment.doctorid = Doctor.doctorId  //have doctorId column common

LEFT JOIN Patient ON Appointment.PatientId = Patient.PatientId      //have patientid column common

WHERE Doctor.Doctorname LIKE 'varun%' // setting doctor name by using LIKE

AND Appointment.AppointmentDateTime BETWEEN '1/16/2001' AND '9/9/2014' //comparison b/w dates 

ORDER BY AppointmentDateTime ASC;  // getting data as ascending order

I wrote the solution to get date format like "mm/dd/yy" (under my name "VARUN TEJ REDDY")

Since the directory is not empty, file.delete() returns false, always.

I used

file.deleteRecursively()

which is available in Kotlin and would delete the completely directly and return the boolean response just as file.delete() does.

Arrays in Java aren't dynamic, like collection classes. If you want a true collection that supports dynamic addition and deletion, use ArrayList<>. If you still want to live with vanilla arrays, find the index of string, construct a new array with size one less than the original, and use System.arraycopy() to copy the elements before and after. Or write a copy loop with skip by hand, on small arrays the difference will be negligible.

You just have to use class="row-eq-height" with your class="row" to get equal height columns for previous bootstrap versions.

but with bootstrap 4 this comes natively.

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";
    }
});

From math lib: https://github.com/golang/go/blob/master/src/math/const.go#L39

package main

import (
    "fmt"
    "math"
)

func main() {
    fmt.Printf("max int64: %d\n", math.MaxInt64)
}

This is what matplotlib.pyplot.scatter is for.

As a quick example:

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
t = np.linspace(0, 2 * np.pi, 20)
x = np.sin(t)
y = np.cos(t)

plt.scatter(t,x,c=y)
plt.show()

You could make two forms with 2 different actions

<form action="login.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Login">
</form>

<br />

<form action="register.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Register">
</form>

Or do this

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="login">
    <input type="submit" value="Login">
</form>

<br />

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="register">
    <input type="submit" value="Register">
</form>

Then you PHP file would work as a switch($_POST['action']) ... furthermore, they can't click on both links at the same time or make a simultaneous request, each submit is a separate request.

Your PHP would then go on with the switch logic or have different php files doing a login procedure then a registration procedure

Yes, it is possible. All you have to do is change your query to something like SELECT i.foo, i.bar FROM ObjectName i WHERE i.id = 10. The result of the query will be a List of array of Object. The first element in each array is the value of i.foo and the second element is the value i.bar. See the relevant section of JPQL reference.

You have to be clear on what you mean by "JSON".

Some people use the term JSON incorrectly to refer to a plain old JavaScript object, such as [{a: 1}]. This one happens to be an array. If you want to add a new element to the array, just push it, as in

var arr = [{a: 1}];
arr.push({b: 2});

< [{a: 1}, {b: 2}]

The word JSON may also be used to refer to a string which is encoded in JSON format:

var json = '[{"a": 1}]';

Note the (single) quotation marks indicating that this is a string. If you have such a string that you obtained from somewhere, you need to first parse it into a JavaScript object, using JSON.parse:

var obj = JSON.parse(json);

Now you can manipulate the object any way you want, including push as shown above. If you then want to put it back into a JSON string, then you use JSON.stringify:

var new_json = JSON.stringify(obj.push({b: 2}));
'[{"a": 1}, {"b": 1}]'

JSON is also used as a common way to format data for transmission of data to and from a server, where it can be saved (persisted). This is where ajax comes in. Ajax is used both to obtain data, often in JSON format, from a server, and/or to send data in JSON format up to to the server. If you received a response from an ajax request which is JSON format, you may need to JSON.parse it as described above. Then you can manipulate the object, put it back into JSON format with JSON.stringify, and use another ajax call to send the data to the server for storage or other manipulation.

You use the term "JSON file". Normally, the word "file" is used to refer to a physical file on some device (not a string you are dealing with in your code, or a JavaScript object). The browser has no access to physical files on your machine. It cannot read or write them. Actually, the browser does not even really have the notion of a "file". Thus, you cannot just read or write some JSON file on your local machine. If you are sending JSON to and from a server, then of course, the server might be storing the JSON as a file, but more likely the server would be constructing the JSON based on some ajax request, based on data it retrieves from a database, or decoding the JSON in some ajax request, and then storing the relevant data back into its database.

Do you really have a "JSON file", and if so, where does it exist and where did you get it from? Do you have a JSON-format string, that you need to parse, mainpulate, and turn back into a new JSON-format string? Do you need to get JSON from the server, and modify it and then send it back to the server? Or is your "JSON file" actually just a JavaScript object, that you simply need to manipulate with normal JavaScript logic?

You can add a class to each of your .row divs to add some space in between them like so:

.spacer {
    margin-top: 40px; /* define margin as you see fit */
}

You can then use it like so:

<div class="row spacer">
   <div class="span4">...</div>
   <div class="span4">...</div>
   <div class="span4">...</div>
</div>

<div class="row spacer">
   <div class="span4">...</div>
   <div class="span4">...</div>
   <div class="span4">...</div>
</div>

Why not to use:

• [ProjectNamespace].Properties.Settings.Default.[KeyProperty] for C#
• My.Settings.[KeyProperty] for VB.NET

You just have to update visually those properties at design-time through:

[Solution Project]->Properties->Settings

You should be able to with a subquery in the INSERT statement.

INSERT INTO table1(column1, column2) SELECT column1, column2 FROM table2 WHERE ...;

followed by deleting from table1.

Remember to run it as a single transaction so that if anything goes wrong you can roll the entire operation back.

If the column is already populated with data and live in production, I'd recommend a step by step approach, so as to avoid downtime in production while waiting for the migrations.

First I'd create a db migration to add columns with the new name(s) and populate them with the values from the old column name.

class AddCorrectColumnNames < ActiveRecord::Migration
  def up
    add_column :table, :correct_name_column_one, :string
    add_column :table, :correct_name_column_two, :string

    puts 'Updating correctly named columns'
    execute "UPDATE table_name SET correct_name_column_one = old_name_column_one, correct_name_column_two = old_name_column_two"
    end
  end

  def down
    remove_column :table, :correct_name_column_one
    remove_column :table, :correct_name_column_two
  end
end

Then I'd commit just that change, and push the change into production.

git commit -m 'adding columns with correct name'

Then once the commit has been pushed into production, I'd run.

Production $ bundle exec rake db:migrate

Then I'd update all of the views/controllers that referenced the old column name to the new column name. Run through my test suite, and commit just those changes. (After making sure it was working locally and passing all tests first!)

git commit -m 'using correct column name instead of old stinky bad column name'

Then I'd push that commit to production.

At this point you can remove the original column without worrying about any sort of downtime associated with the migration itself.

class RemoveBadColumnNames < ActiveRecord::Migration
  def up
    remove_column :table, :old_name_column_one
    remove_column :table, :old_name_column_two
  end

  def down
    add_column :table, :old_name_column_one, :string
    add_column :table, :old_name_column_two, :string
  end
end

Then push this latest migration to production and run bundle exec rake db:migrate in the background.

I realize this is a bit more involved of a process, but I'd rather do this than have issues with my production migration.

Just to make it simple: The solution is just to enable vt-x or Virtualization Technology in bios, which is under Advanced Tab. and once it's enabled, the error disappears.

FYI I had similar issues starting up my Android emulators in Appium studio for my mobile testing, and on top, I had latest bios, which looked so different to the standard one.
So attaching screenshot of my computer bios, but the option should be there on any Bios settings. Just need to boot the computer, and push Esc or some function key to see the computer bios, and then find the correct option to enable it under Advanced Tab, (most importantly, you may have to scroll down as the option would be down the list) I left my Hyper-V feature as is, which was enabled though.

let indexPathRow:Int = 0
let indexPosition = IndexPath(row: indexPathRow, section: 0)
tableView.reloadRows(at: [indexPosition], with: .none)

This condition check

if (!!foo) {
    //foo is defined
}

is all you need.

import datetime and then the magic timedelta stuff:

In [63]: datetime.datetime.now()
Out[63]: datetime.datetime(2010, 12, 27, 14, 39, 19, 700401)

In [64]: datetime.datetime.now() - datetime.timedelta(minutes=15)
Out[64]: datetime.datetime(2010, 12, 27, 14, 24, 21, 684435)

There's a fairly simple and (IMO) elegant approach, at least for durations of less than 24 hours:

DateTimeFormatter.ISO_LOCAL_TIME.format(value.addTo(LocalTime.of(0, 0)))

Formatters need a temporal object to format, so you can create one by adding the duration to a LocalTime of 00:00 (i.e. midnight). This will give you a LocalTime representing the duration from midnight to that time, which is then easy to format in standard HH:mm:ss notation. This has the advantage of not needing an external library, and uses the java.time library to do the calculation, rather than manually calculating the hours, minutes and seconds.

You have to call DataReader.Read to fetch the result:

SqlDataReader dr = cmd10.ExecuteReader();
if (dr.Read()) 
{
    // read data for first record here
}

DataReader.Read() returns a bool indicating if there are more blocks of data to read, so if you have more than 1 result, you can do:

while (dr.Read()) 
{
    // read data for each record here
}

I needed to find out how many duplicates there were and what they were so I wrote a function building off of what Naveed had posted earlier:

def print_duplicates(array)
  puts "Array count: #{array.count}"
  map = {}
  total_dups = 0
  array.each do |v|
    map[v] = (map[v] || 0 ) + 1
  end

  map.each do |k, v|
    if v != 1
      puts "#{k} appears #{v} times"
      total_dups += 1
    end
  end
  puts "Total items that are duplicated: #{total_dups}"
end

Well, the <head> tag has nothing to do with the <header> tag. In the head comes all the metadata and stuff, while the header is just a layout component.
And layout comes into body. So I disagree with you.

1. right click the highlight whose color you want to change

2. select "Preference"

3. ->General->Editors->Text Editors->Annotations->Occurrences->Text as Hightlited->color.

4. Select "Preference ->java->Editor->Restore Defaults

This is a segfault due to following a null pointer trying to find code to run (that is, during an instruction fetch).

If this were a program, not a shared library

Run addr2line -e yourSegfaultingProgram 00007f9bebcca90d (and repeat for the other instruction pointer values given) to see where the error is happening. Better, get a debug-instrumented build, and reproduce the problem under a debugger such as gdb.

Since it's a shared library

You're hosed, unfortunately; it's not possible to know where the libraries were placed in memory by the dynamic linker after-the-fact. Reproduce the problem under gdb.

What the error means

Here's the breakdown of the fields:

• address (after the at) - the location in memory the code is trying to access (it's likely that 10 and 11 are offsets from a pointer we expect to be set to a valid value but which is instead pointing to 0)
• ip - instruction pointer, ie. where the code which is trying to do this lives
• sp - stack pointer

• error - An error code for page faults; see below for what this means on x86.

  /*
   * Page fault error code bits:
   *
   *   bit 0 ==    0: no page found       1: protection fault
   *   bit 1 ==    0: read access         1: write access
   *   bit 2 ==    0: kernel-mode access  1: user-mode access
   *   bit 3 ==                           1: use of reserved bit detected
   *   bit 4 ==                           1: fault was an instruction fetch
   */

I suppose you are using a LinearLayoutManager to show the list. It has a nice method called findViewByPosition that

Finds the view which represents the given adapter position.

All you need is the adapter position of the item you are interested in.

edit: as noted by Paul Woitaschek in the comments, findViewByPosition is a method of LayoutManager so it would work with all LayoutManagers (i.e. StaggeredGridLayoutManager, etc.)

I prefer option two because it clearly shows the list item as the possessor of that nested list. I would always lean towards semantically sound HTML.

Just pass it as an array:

$data = [
    'name'  => 'Raphael',
    'age'   => 22,
    'email' => '[email protected]'
];

return View::make('user')->with($data);

Or chain them, like @Antonio mentioned.

This post is for Sublime 3.

I just installed Sublime 3, the 64 bit version, on Ubuntu 14.04. I can't tell the difference between this version and Sublime 2 as far as user interface. The reason I didn't go with Sublime 2 is that it gives an annoying "GLib critical" error messages.

Anyways - previous posts mentioned the file /sublime_text_3/Packages/Color\ Scheme\ -\ Default.sublime-package

I wanted to give two tips here with respect to this file in Sublime 3:

1. You can edit it with pico and use ^W to search the theme name. The first search result will bring you to an XML style entry where you can change the values. Make a copy before you experiment.
2. If you choose the theme in the sublime menu (under Preferences/Color Scheme) before you change this file, then the changes will be cached and your change will not take effect. So delete the cached version and restart sublime for the changes to take effect. The cached version is at ~/.config/sublime-text-3/Cache/Color Scheme - Default/

Not tested, but I think you can do the following:

dataGrid.Rows[index].Selected = true;

or you could do the following (but again: not tested):

dataGrid.SelectedRows.Clear();
foreach(DataGridViewRow row in dataGrid.Rows)
{
    if(YOUR CONDITION)
       row.Selected = true;
}

For me, using EF6 and Visual Studio 2015 I entered query in the immediate window and it gave me the generated SQL Statement

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

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

You can simply add another level of depth to your virtual bundle path

    //Two levels deep bundle path so that paths are maintained after minification
    bundles.Add(new StyleBundle("~/Content/css/css").Include("~/Content/bootstrap/bootstrap.css", "~/Content/site.css"));

This is a super low-tech answer and kind of a hack but it works and won't require any pre-processing. Given the length and complexity of some of these answers I prefer doing it this way.

There are two general ways of doing that. You will either create a Domain Object Model of that XML file, take a look at this

and the second choice is using event driven parsing, which is an alternative to DOM xml representation. Imho you can find the best overall comparison of these two basic techniques here. Of course there are much more to know about processing xml, for instance if you are given XML schema definition (XSD), you could use JAXB.

Thats what i am using try it.

<a href="index.php"><button style ="position:absolute;top:450px;left:1100px;height:30px;width:200px;"> Cancel </button></a>

I just wanted to mention something a little strange to me when I first encountered this.

I needed to initialize a private static data member in a template class.

in the .h or .hpp, it looks something like this to initialize a static data member of a template class:

template<typename T>
Type ClassName<T>::dataMemberName = initialValue;

**In this function you can able to split the function by golang using array of strings**

func SplitCmdArguments(args []string) map[string]string {
    m := make(map[string]string)
    for _, v := range args {
        strs := strings.Split(v, "=")
        if len(strs) == 2 {
            m[strs[0]] = strs[1]
        } else {
            log.Println("not proper arguments", strs)
        }
    }
    return m
}

You also can check input mask formatter.

This is a directive and it's called ui-mask and also it's a part of angular-ui.utils library.

Here is working: Live example

For the time of writing this post there aren't any examples of using this directive, so I've made a very simple example to demonstrate how this thing works in practice.

You need to use $_POST not $_post.

"N/A" is a string and cannot be converted to a number. Catch the exception and handle it. For example:

    String text = "N/A";
    int intVal = 0;
    try {
        intVal = Integer.parseInt(text);
    } catch (NumberFormatException e) {
        //Log it if needed
        intVal = //default fallback value;
    }

  public static bool IsPropertyExist(dynamic settings, string name)
  {
    if (settings is ExpandoObject)
      return ((IDictionary<string, object>)settings).ContainsKey(name);

    return settings.GetType().GetProperty(name) != null;
  }

  var settings = new {Filename = @"c:\temp\q.txt"};
  Console.WriteLine(IsPropertyExist(settings, "Filename"));
  Console.WriteLine(IsPropertyExist(settings, "Size"));

Output:

 True
 False

If you need to echo a string that contains an ampersand, quotes won't help, because you would see them on the output as well. In such a case, use for:

for %a in ("First & Last") do echo %~a

...in a batch script:

for %%a in ("First & Last") do echo %%~a

or

for %%a in ("%~1") do echo %%~a

If anyone like me is still unable to register ASP.NET with IIS.

You just need to run these three commands one by one in command prompt

cd c:\windows\Microsoft.Net\Framework\v2.0.50727

after that, Run

aspnet_regiis.exe -i -enable

and Finally Reset IIS

iisreset

Hope it helps the person in need... cheers!

I've solve the issue. The solution is to not making virtual dir manualy and then copy app files here, but use 'Add Application...' option. Here is post that helped me http://social.msdn.microsoft.com/Forums/en-US/winformssetup/thread/7ad2acb0-42ca-4ee8-9161-681689b60dda/

I was able to figure out the solution:

start notepad "myfile.txt"
"myshortcut.lnk"
exit

You need the secret string which was used to generate encrypt token. This code works for me:

protected string GetName(string token)
    {
        string secret = "this is a string used for encrypt and decrypt token"; 
        var key = Encoding.ASCII.GetBytes(secret);
        var handler = new JwtSecurityTokenHandler();
        var validations = new TokenValidationParameters
        {
            ValidateIssuerSigningKey = true,
            IssuerSigningKey = new SymmetricSecurityKey(key),
            ValidateIssuer = false,
            ValidateAudience = false
        };
        var claims = handler.ValidateToken(token, validations, out var tokenSecure);
        return claims.Identity.Name;
    }

svn status | grep "^\?" | awk '{print $2}' | xargs svn add

Taken from somewhere on the web but I've been using it for a while and it works well.

I've experienced the same problem and now I just found my solution to this issue.

#!/usr/bin/python

import sys
import os

os.system('meld "%s" "%s"' % (sys.argv[2], sys.argv[5]))

This is the code[1] for my case. When I tried this script I received error message like :

import: command not found

I found people talks about the shebang. As you see there is the shebang in my python code above. I tried these and those trials but didn't find a good solution.

I finally tried to type the shebang my self.

#!/usr/bin/python

and removed the copied one.

And my problem solved!!!

I copied the code from the internet[1].

And I guess there had been some unseeable(?) unseen special characters in the original copied shebang statement.

I use vim, sometimes I experience similar problems.. Especially when I copied some code snippet from the internet this kind of problems happen.. Web pages have some virus special characters!! I doubt. :-)

PS) I copied the code in Windows 7 - host OS - into the Windows clipboard and pasted it into my vim in Ubuntu - guest OS. VM is Oracle Virtual Machine.

If you are parsing string data from the console or similar, the best way is to use regular expressions. Read more on that here: http://java.sun.com/developer/technicalArticles/releases/1.4regex/

Otherwise, to parse an int from a string, try Integer.parseInt(string). If the string is not a number, you will get an exception. Otherise you can then perform your checks on that value to make sure it is not negative.

String input;
int number;
try
{
    number = Integer.parseInt(input);
    if(number > 0)
    {
        System.out.println("You positive number is " + number);
    }
} catch (NumberFormatException ex)
{
     System.out.println("That is not a positive number!");
}

To get a character-only string, you would probably be better of looping over each character checking for digits, using for instance Character.isLetter(char).

String input
for(int i = 0; i<input.length(); i++)
{
   if(!Character.isLetter(input.charAt(i)))
   {
      System.out.println("This string does not contain only letters!");
      break;
   }
}

Good luck!

Make sure the value is in the other table otherwise you will get this error, in the assigned corresponding column.

So if it is assigned column is assigned to a row id of another table , make sure there is a row that is in the table otherwise this error will appear.

To keep open your windows console and to not use other output methods rather than the standard output stream cout go to Name-of-your-project -> Properties -> Linker -> System.

Once there, select the SubSytem Tab and mark Console (/SUBSYSTEM:CONSOLE). Once you have done this, whenever you want to compile use Ctrl + F5 (Start without debugging) and your console will keep opened. :)

In this specific example, where the DataFrame is only one column, you can write this elegantly as:

df['desired_output'] = df.le(2.5)

le tests whether elements are less than or equal 2.5, similarly lt for less than, gt and ge.

Like this:

from c in db.Company
group c by c.Name into grp
where grp.Count() > 1
select grp.Key

Or, using the method syntax:

Company
    .GroupBy(c => c.Name)
    .Where(grp => grp.Count() > 1)
    .Select(grp => grp.Key);

at least pip3 also works without "=", however, instead of "http" you might need "https"

Final command, which worked for me:

sudo pip3 install --proxy https://{proxy}:{port} {BINARY}

How are you setting up the SqlParameter? You should set the SqlDbType property to SqlDbType.DateTime and then pass the DateTime directly to the parameter (do NOT convert to a string, you are asking for a bunch of problems then).

You should be able to get the value into the DB. If not, here is a very simple example of how to do it:

static void Main(string[] args)
{
    // Create the connection.
    using (SqlConnection connection = new SqlConnection(@"Data Source=..."))
    {
        // Open the connection.
        connection.Open();

        // Create the command.
        using (SqlCommand command = new SqlCommand("xsp_Test", connection))
        {
            // Set the command type.
            command.CommandType = System.Data.CommandType.StoredProcedure;

            // Add the parameter.
            SqlParameter parameter = command.Parameters.Add("@dt",
                System.Data.SqlDbType.DateTime);

            // Set the value.
            parameter.Value = DateTime.Now;

            // Make the call.
            command.ExecuteNonQuery();
        }
    }
}

I think part of the issue here is that you are worried that the fact that the time is in UTC is not being conveyed to SQL Server. To that end, you shouldn't, because SQL Server doesn't know that a particular time is in a particular locale/time zone.

If you want to store the UTC value, then convert it to UTC before passing it to SQL Server (unless your server has the same time zone as the client code generating the DateTime, and even then, that's a risk, IMO). SQL Server will store this value and when you get it back, if you want to display it in local time, you have to do it yourself (which the DateTime struct will easily do).

All that being said, if you perform the conversion and then pass the converted UTC date (the date that is obtained by calling the ToUniversalTime method, not by converting to a string) to the stored procedure.

And when you get the value back, call the ToLocalTime method to get the time in the local time zone.

CASE is an expression - it returns a single scalar value (per row). It can't return a complex part of the parse tree of something else, like an ORDER BY clause of a SELECT statement.

It looks like you just need:

ORDER BY 
CASE WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount END desc,
CASE WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount END desc, 
Case WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount END DESC,
CASE WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount END DESC,
Case WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount END DESC,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

Or possibly:

ORDER BY 
CASE
   WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount
   WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount
   WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount
   WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount
   WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount
END desc,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

It's a little tricky to tell which of the above (or something else) is what you're looking for because you've a) not explained what actual sort order you're trying to achieve, and b) not supplied any sample data and expected results, from which we could attempt to deduce the actual sort order you're trying to achieve.

This may be the answer we're looking for:

ORDER BY 
CASE
   WHEN TblList.PinRequestCount <> 0 THEN 5
   WHEN TblList.HighCallAlertCount <> 0 THEN 4
   WHEN TblList.HighAlertCount <> 0 THEN 3
   WHEN TblList.MediumCallAlertCount <> 0 THEN 2
   WHEN TblList.MediumAlertCount <> 0 THEN 1
END desc,
CASE
   WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount
   WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount
   WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount
   WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount
   WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount
END desc,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

Linking to my answer on a duplicate question. Not only is the URL available in the browsers history, the server side logs but it's also sent as the HTTP Referer header which if you use third party content, exposes the URL to sources outside your control.

Tested answer:

In the .view-row css, change:

display:table-row;

to:

display:table

and get rid of "float". Everything will work as expected.

As it has been suggested in the comments, there is no need for a wrapping table. CSS allows for omitting levels of the tree structure (in this case rows) that are implicit. The reason your code doesn't work is that "width" can only be interpreted at the table level, not at the table-row level. When you have a "table" and then "table-cell"s directly underneath, they're implicitly interpreted as sitting in a row.

Working example:

<div class="view">
    <div>Type</div>
    <div>Name</div>                
</div>

with css:

.view {
  width:100%;
  display:table;
}

.view > div {
  width:50%;
  display: table-cell;
}

This article helped me a lot in understanding the concept.

In summary,

• Both are probabilistic models, meaning they both use probability (conditional probability , to be precise) to calculate classes for the unknown data.
• The Generative Classifiers apply Joint PDF & Bayes Theorem on the data set and calculate conditional probability using values from those.
• The Discriminative Classifiers directly find Conditional probablity on the data set

Some good reading material: conditional probability , Joint PDF

Move your javascript into a function and then bind that function to window resize.

$(document).ready(function () {
    updateContainer();
    $(window).resize(function() {
        updateContainer();
    });
});
function updateContainer() {
    var $containerHeight = $(window).height();
    if ($containerHeight <= 818) {
        $('.footer').css({
            position: 'static',
            bottom: 'auto',
            left: 'auto'
        });
    }
    if ($containerHeight > 819) {
        $('.footer').css({
            position: 'absolute',
            bottom: '3px',
            left: '0px'
        });
    }
}

Create .bat file:

start javaw -jar %*

And choose app default to open .jar with this .bat file.

It will close cmd when start your .jar file.

Even better when choosing the Assembly location. Filter most of the assemblies if you know all your implemented interfaces are within the same Assembly.DefinedTypes.

// We get the assembly through the base class
var baseAssembly = typeof(baseClass).GetTypeInfo().Assembly;

// we filter the defined classes according to the interfaces they implement
var typeList = baseAssembly.DefinedTypes.Where(type => type.ImplementedInterfaces.Any(inter => inter == typeof(IMyInterface))).ToList();

Wikipedia (or rather, the community on Wikipedia) keeps a pretty good up-to-date list here.

• Most browsers are on 1.5 (though they have features of later versions)
• Mozilla progresses with every dot release (they maintain the standard so that's not surprising)
• Firefox 4 is on JavaScript 1.8.5
• The other big off-the-beaten-path one is IE9 - it implements ECMAScript 5, but doesn't implement all the features of JavaScript 1.8.5 (not sure what they're calling this version of JScript, engine codenamed Chakra, yet).

This is typically done manually by choosing the appropriate bits from the vector and then appending 0s.

For example, to shift a vector 8 bits

variable tmp : std_logic_vector(15 downto 0)
...
tmp := x"00" & tmp(15 downto 8);

Hopefully this simple answer is useful to someone

The two functions do vastly different things!

The resize() method (and passing argument to constructor is equivalent to that) will insert or delete appropriate number of elements to the vector to make it given size (it has optional second argument to specify their value). It will affect the size(), iteration will go over all those elements, push_back will insert after them and you can directly access them using the operator[].

The reserve() method only allocates memory, but leaves it uninitialized. It only affects capacity(), but size() will be unchanged. There is no value for the objects, because nothing is added to the vector. If you then insert the elements, no reallocation will happen, because it was done in advance, but that's the only effect.

So it depends on what you want. If you want an array of 1000 default items, use resize(). If you want an array to which you expect to insert 1000 items and want to avoid a couple of allocations, use reserve().

EDIT: Blastfurnace's comment made me read the question again and realize, that in your case the correct answer is don't preallocate manually. Just keep inserting the elements at the end as you need. The vector will automatically reallocate as needed and will do it more efficiently than the manual way mentioned. The only case where reserve() makes sense is when you have reasonably precise estimate of the total size you'll need easily available in advance.

EDIT2: Ad question edit: If you have initial estimate, then reserve() that estimate. If it turns out to be not enough, just let the vector do it's thing.

Because I dislike seeing "HTTPContext.Current.Session" about the place, I use a singleton pattern to access session variables, it gives you an easy to access strongly typed bag of data.

[Serializable]
public sealed class SessionSingleton
{
    #region Singleton

    private const string SESSION_SINGLETON_NAME = "Singleton_502E69E5-668B-E011-951F-00155DF26207";

    private SessionSingleton()
    {

    }

    public static SessionSingleton Current
    {
        get
        {
            if ( HttpContext.Current.Session[SESSION_SINGLETON_NAME] == null )
            {
                HttpContext.Current.Session[SESSION_SINGLETON_NAME] = new SessionSingleton();
            }

            return HttpContext.Current.Session[SESSION_SINGLETON_NAME] as SessionSingleton;
        }
    }

    #endregion

    public string SessionVariable { get; set; }
    public string SessionVariable2 { get; set; }

    // ...

then you can access your data from anywhere:

SessionSingleton.Current.SessionVariable = "Hello, World!";
