The answer from ks1322 helped me to identify the issue while using docker-compose exec:

If you omit the -T flag, docker-compose exec add a special character that break output, we see b instead of 1b:

$ test=$(/usr/local/bin/docker-compose exec db bash -c "echo 1")
$ echo "${test}b"
b

echo "${test}" | cat -vte
1^M$

With -T flag, docker-compose exec works as expected:

$ test=$(/usr/local/bin/docker-compose exec -T db bash -c "echo 1")
$ echo "${test}b"
1b

The command above worked for me

A good answer already, but there are a couple of other ways to do this:

unique(c[c%in%a[a%in%b]])

or,

tst <- c(unique(a),unique(b),unique(c))
tst <- tst[duplicated(tst)]
tst[duplicated(tst)]

You can obviously omit the unique calls if you know that there are no repeated values within a, b or c.

This is how I solved it without using custom helpers or extensions with .NET core 3.1.

Class

public enum YourEnum
{
    [Display(Name = "Suryoye means Arameans")]
    SURYOYE = 0,
    [Display(Name = "Oromoye means Syriacs")]
    OROMOYE = 1,
}

Razor

@using Enumerations

foreach (var name in Html.GetEnumSelectList(typeof(YourEnum)))
{
    <h1>@name.Text</h1>
}

Here you go:

public static byte[] ConvertToByteArray(string str, Encoding encoding)
{
    return encoding.GetBytes(str);
}

public static String ToBinary(Byte[] data)
{
    return string.Join(" ", data.Select(byt => Convert.ToString(byt, 2).PadLeft(8, '0')));
}

// Use any sort of encoding you like. 
var binaryString = ToBinary(ConvertToByteArray("Welcome, World!", Encoding.ASCII));

The selector criteria is now an attribute the DIV tag.

examples are ...

data-date-format="dd MM yyyy" 
data-date-format="dd MM yyyy - HH:ii p
data-date-format="hh:ii"

so the bootstrap example for dd mm yyyy is:-

<div class="input-group date form_date col-md-5" data-date="" 
    data-date-format="dd MM yyyy" data-link-field="dtp_input2" data-link-format="yyyy-mm-dd">
..... etc ....
</div>

my Javascript settings are as follows:-

            var picker_settings = {
                language:  'en',
                weekStart: 1,
                todayBtn:  1,
                autoclose: 1,
                todayHighlight: 1,
                startView: 2,
                minView: 2,
                forceParse: 0
            };

        $(datePickerId).datetimepicker(picker_settings);

You can see working examples of these if you download the bootstrap-datetimepicker-master file. There are sample folders each with an index.html.

I have modified working solution to handle both the case.. when video is uploaded and when image is uploaded .. hope it will help some.

There are some cases can lead to this issue, if it occered in the middle of the code it will be "IndentationError: expected an indented block" or "SyntaxError: invalid syntax", if it at the last line it may "SyntaxError: unexpected EOF while parsing":

Missing the body of "if","while"and"for" statement-->

Both the size attribute in HTML and the width property in CSS will set the width of an <input>. If you want to set the width to something closer to the width of each character use the **ch** unit as in:

input {
    width: 10ch;
}

class App():
    def __init__(self):
        self.root = Tkinter.Tk()
        button = Tkinter.Button(self.root, text = 'root quit', command=self.quit)
        button.pack()
        self.root.mainloop()

    def quit(self):
        self.root.destroy()

app = App()

you could add an sed script to your commandline:

ls /home/user/new/*.txt | sed -r 's/^.+\///'

json.dumps() converts a dictionary to str object, not a json(dict) object! So you have to load your str into a dict to use it by using json.loads() method

See json.dumps() as a save method and json.loads() as a retrieve method.

This is the code sample which might help you understand it more:

import json

r = {'is_claimed': 'True', 'rating': 3.5}
r = json.dumps(r)
loaded_r = json.loads(r)
loaded_r['rating'] #Output 3.5
type(r) #Output str
type(loaded_r) #Output dict

There are already great answers about the advantages of using list initialization, however my personal rule of thumb is NOT to use curly braces whenever possible, but instead make it dependent on the conceptual meaning:

• If the object I'm creating conceptually holds the values I'm passing in the constructor (e.g. containers, POD structs, atomics, smart pointers etc.), then I'm using the braces.
• If the constructor resembles a normal function call (it performs some more or less complex operations that are parametrized by the arguments) then I'm using the normal function call syntax.
• For default initialization I always use curly braces.
  For one, that way I'm always sure that the object gets initialized irrespective of whether it e.g. is a "real" class with a default constructor that would get called anyway or a builtin / POD type. Second it is - in most cases - consistent with the first rule, as a default initialized object often represents an "empty" object.

In my experience, this ruleset can be applied much more consistently than using curly braces by default, but having to explicitly remember all the exceptions when they can't be used or have a different meaning than the "normal" function-call syntax with parenthesis (calls a different overload).

It e.g. fits nicely with standard library-types like std::vector:

vector<int> a{10,20};   //Curly braces -> fills the vector with the arguments

vector<int> b(10,20);   //Parentheses -> uses arguments to parametrize some functionality,                          
vector<int> c(it1,it2); //like filling the vector with 10 integers or copying a range.

vector<int> d{};      //empty braces -> default constructs vector, which is equivalent
                      //to a vector that is filled with zero elements

MySQL allows a more readable way to combine multiple updates into a single query. This seems to better fit the scenario you describe, is much easier to read, and avoids those difficult-to-untangle multiple conditions.

INSERT INTO table_users (cod_user, date, user_rol, cod_office)
VALUES
('622057', '12082014', 'student', '17389551'),
('2913659', '12082014', 'assistant','17389551'),
('6160230', '12082014', 'admin', '17389551')
ON DUPLICATE KEY UPDATE
 cod_user=VALUES(cod_user), date=VALUES(date)

This assumes that the user_rol, cod_office combination is a primary key. If only one of these is the primary key, then add the other field to the UPDATE list. If neither of them is a primary key (that seems unlikely) then this approach will always create new records - probably not what is wanted.

However, this approach makes prepared statements easier to build and more concise.

string directoryPath = Path.GetDirectoryName(destinationFileName);

// If directory doesn't exist create one
if (!Directory.Exists(directoryPath))
{
DirectoryInfo di = Directory.CreateDirectory(directoryPath);
}

File.Copy(sourceFileName, destinationFileName);

To return a different view, you can specify the name of the view you want to return and model as follows:

return View("ViewName", yourModel);

if the view is in different folder under Views folder then use below absolute path:

return View("~/Views/FolderName/ViewName.aspx");

Error:

If you're unsure why you're getting above error read on.
Due to the nature of the syntax above problem might occur because:
1. This exception might occur in wrongly written multi-threaded
tests.
Please refer to Mockito FAQ on limitations of concurrency testing.
2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to
stub spies -
- with doReturn|Throw() family of methods. More in javadocs for
Mockito.spy() method.

Actual Code:

@RunWith(PowerMockRunner.class)
@PrepareForTest({ Object.class, ByteString.class})

@Mock
private ByteString mockByteString;

String testData = “dsfgdshf”;
PowerMockito.when(mockByteString.toStringUtf8()).thenReturn(testData); 
// throws above given exception

Solution to fix this issue:

1st Remove annotation “@Mock”.

private ByteString mockByteString;

2nd Add PowerMockito.mock

mockByteString = PowerMockito.mock(ByteString.class);

For my Case in 'Path' variable there was a parameter added like 'C:\ProgramData\Oracle\Java\javapath;'. This location was having java.exe, javaw.exe and javaws.exe from java 8 which is newly installed via jdk.exe from Oracle.

I've removed this text from Path where my Path already having %JAVA_HOME%\bin with it.

Now, the variable 'JAVA_HOME' is controlling my Java version which is I wanted.

You should override by increasing Specificity of your styling. There are different ways of increasing the Specificity. Usage of !important which effects specificity, is a bad practice because it breaks natural cascading in your style sheet.

Following diagram taken from css-tricks.com will help you produce right specificity for your element based on a points structure. Whichever specificity has higher points, will win. Sounds like a game - doesn't it?

Checkout sample calculations here on css-tricks.com. This will help you understand the concept very well and it will only take 2 minutes.

If you then like to produce and/or compare different specificities by yourself, try this Specificity Calculator: https://specificity.keegan.st/ or you can just use traditional paper/pencil.

For further reading try MDN Web Docs.

All the best for not using !important.

I was inspired of Jason's function and made a little improvements to it and got as a result rather fast finder:

function timo_longest(a) {
  var c = 0, d = 0, l = 0, i = a.length;
  if (i) while (i--) {
    d = a[i].length;
    if (d > c) {
      l = i; c = d;
    }
  }
  return a[l];
}
arr=["First", "Second", "Third"];
var longest = timo_longest(arr);

Speed results: http://jsperf.com/longest-string-in-array/7

Try this:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    // You may decide to prompt to user else just kill.
    Process.GetCurrentProcess().Goose();
} 

There is a getch() function in the ncurses library. You can get it by installing the ncurses-dev package.

If Ruby is installed, then

ruby yourfile.rb

where yourfile.rb is the file containing the ruby code.

Or

irb

to start the interactive Ruby environment, where you can type lines of code and see the results immediately.

You can use Java 8 Stream API.

Method distinct is an intermediate operation that filters the stream and allows only distinct values (by default using the Object::equals method) to pass to the next operation.
I wrote an example below for your case,

// Create the list with duplicates.
List<String> listAll = Arrays.asList("CO2", "CH4", "SO2", "CO2", "CH4", "SO2", "CO2", "CH4", "SO2");

// Create a list with the distinct elements using stream.
List<String> listDistinct = listAll.stream().distinct().collect(Collectors.toList());

// Display them to terminal using stream::collect with a build in Collector.
String collectAll = listAll.stream().collect(Collectors.joining(", "));
System.out.println(collectAll); //=> CO2, CH4, SO2, CO2, CH4 etc..
String collectDistinct = listDistinct.stream().collect(Collectors.joining(", "));
System.out.println(collectDistinct); //=> CO2, CH4, SO2

The following is something I used that worked for me across browsers so I hope it helps someone in the future:

#contentblock th:first-child {
    -moz-border-radius: 6px 0 0 0;
    -webkit-border-radius: 6px 0 0 0;
    border-radius: 6px 0 0 0;
    behavior: url(/images/border-radius.htc);
    border-radius: 6px 0 0 0;
}

#contentblock th:last-child {
    -moz-border-radius: 0 6px 0 0;
    -webkit-border-radius: 0 6px 0 0;
    border-radius: 0 6px 0 0;
    behavior: url(/images/border-radius.htc);
    border-radius: 0 6px 0 0;
}
#contentblock tr:last-child td:last-child {
     border-radius: 0 0 6px 0;
    -moz-border-radius: 0 0 6px 0;
    -webkit-border-radius: 0 0 6px 0;
    behavior: url(/images/border-radius.htc);
    border-radius: 0 0 6px 0;
 }

#contentblock tr:last-child td:first-child {
    -moz-border-radius: 0 0 0 6px;
    -webkit-border-radius: 0 0 0 6px;
    border-radius: 0 0 0 6px;
    behavior: url(/images/border-radius.htc);
    border-radius: 0 0 0 6px;
}

Obviously the #contentblock portion can be replaced/edited as needed and you can find the border-radius.htc file by doing a search in Google or your favorite web browser.

you can use triggers. works very well

CREATE TABLE MyTable(
ID INTEGER PRIMARY KEY,
Name TEXT,
Other STUFF,
Timestamp DATETIME);


CREATE TRIGGER insert_Timestamp_Trigger
AFTER INSERT ON MyTable
BEGIN
   UPDATE MyTable SET Timestamp =STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW') WHERE id = NEW.id;
END;

CREATE TRIGGER update_Timestamp_Trigger
AFTER UPDATE On MyTable
BEGIN
   UPDATE MyTable SET Timestamp = STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW') WHERE id = NEW.id;
END;

I've found that there will be a new version of npm 5.7.1 with the new command npm ci, that will install from package-lock.json only

The new npm ci command installs from your lock-file ONLY. If your package.json and your lock-file are out of sync then it will report an error.

It works by throwing away your node_modules and recreating it from scratch.

Beyond guaranteeing you that you'll only get what is in your lock-file it's also much faster (2x-10x!) than npm install when you don't start with a node_modules.

As you may take from the name, we expect it to be a big boon to continuous integration environments. We also expect that folks who do production deploys from git tags will see major gains.

Like with every bad software the treatment for this wrong behaivier does not exist. What is good for one does not work for others.

very good explanation on this post.

http://useyourloaf.com/blog/2010/10/02/dynamically-loading-new-rows-into-a-table.html

simple you have to add last row and hide it and when table row hit last row than show the row and load more items.

From PEP-8: Package and Module Names:

Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability.

Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

When an extension module written in C or C++ has an accompanying Python module that provides a higher level (e.g. more object oriented) interface, the C/C++ module has a leading underscore (e.g. _socket).

The HTML code is for three div align side by side and can be used for two also by some changes

<div id="wrapper">
  <div id="first">first</div>
  <div id="second">second</div>
  <div id="third">third</div>
</div>

The CSS will be

#wrapper {
  display:table;
  width:100%;
}
#row {
  display:table-row;
}
#first {
  display:table-cell;
  background-color:red;
  width:33%;
}
#second {
  display:table-cell;
  background-color:blue;
  width:33%;
}
#third {
  display:table-cell;
  background-color:#bada55;
  width:34%;
}

This code will workup towards responsive layout as it will resize the

<div> 

according to device width. Even one can silent anyone

<div>

as

<!--<div id="third">third</div> --> 

and can use rest two for two

<div> 

side by side.

There are apparently distributions or custom builds in which the ability to set Task Tags for non-Java files is not present. This post mentions that ColdFusion Builder (built on Eclipse) does not let you set non-Java Task Tags, but the beta version of CF Builder 2 does. (I know the OP wasn't using CF Builder, but I am, and I was wondering about this question myself ... because he didn't see the ability to set non-Java tags, I thought others might be in the same position.)

You need to Add C:\Program Files\nodejs to your PATH environment variable. To do this follow these steps:

1. Use the global Search Charm to search "Environment Variables"
2. Click "Edit system environment variables"
3. Click "Environment Variables" in the dialog.
4. In the "System Variables" box, search for Path and edit it to include C:\Program Files\nodejs. Make sure it is separated from any other paths by a ;.

You will have to restart any currently-opened command prompts before it will take effect.

The easiest way according to me will be using SDWebImage

Add this to your pod file

  pod 'SDWebImage', '~> 4.0'

Run pod install

Now import SDWebImage

      import SDWebImage

Now for setting image from url

    imageView.sd_setImage(with: URL(string: "http://www.domain/path/to/image.jpg"), placeholderImage: UIImage(named: "placeholder.png"))

It will show placeholder image but when image is downloaded it will show the image from url .Your app will never crash

This are the main feature of SDWebImage

Categories for UIImageView, UIButton, MKAnnotationView adding web image and cache management

An asynchronous image downloader

An asynchronous memory + disk image caching with automatic cache expiration handling

A background image decompression

A guarantee that the same URL won't be downloaded several times

A guarantee that bogus URLs won't be retried again and again

A guarantee that main thread will never be blocked Performances!

Use GCD and ARC

To know more https://github.com/rs/SDWebImage

An even quicker (and dirtier) way to accomplish this is by setting the UILabel's line break mode to "Clip" and adding a fixed amount of newlines.

myLabel.lineBreakMode = UILineBreakModeClip;
myLabel.text = [displayString stringByAppendingString:"\n\n\n\n"];

This solution won't work for everyone -- in particular, if you still want to show "..." at the end of your string if it exceeds the number of lines you're showing, you'll need to use one of the longer bits of code -- but for a lot of cases this'll get you what you need.

Can be achieved also with scriptrunner

ScriptRunner.exe -appvscript demoA.cmd arg1 arg2 -appvscriptrunnerparameters -wait -timeout=30 -rollbackonerror -appvscript demoB.ps1 arg3 arg4 -appvscriptrunnerparameters -wait -timeout=30 

Which also have some features as rollback , timeout and waiting.

Inspired from Robert's answer, but when we use,

ng-click="searchAll = null" in the filter, it makes the model values as null and in-turn the search doesn't work with its normal functionality, so it would be better enough to use ng-click="searchAll = ''" instead

The -k option is what you want.

-k 1.4,1.5n -k 1.14,1.15n

Would use character positions 4-5 in the first field (it's all one field for fixed width) and sort numerically as the first key.

The second key would be characters 14-15 in the first field also.

(edit)

Example (all I have is DOS/cygwin handy):

dir | \cygwin\bin\sort.exe -k 1.4,1.5n -k 1.40,1.60r

for the data:

12/10/2008  01:10 PM         1,564,990 outfile.txt

Sorts the directory listing by month number (pos 4-5) numerically, and then by filename (pos 40-60) in reverse. Since there are no tabs, it's all field 1 to sort.

Piggybacking off of jonnii:

Topic.find(:all, :conditions => ['forum_id not in (?)', @forums.pluck(:id)])

using pluck rather than mapping over the elements

found via railsconf 2012 10 things you did not know rails could do

times = function () {
    var length = arguments.length;
    for (var i = 0; i < length ; i++) {
        for (var j = 0; j < arguments[i]; j++) {
            dosomthing();
        }
    }
}

You can call it like this:

times(3,4);
times(1,2,3,4);
times(1,3,5,7,9);

I had this question twice, and it was always caused by the corruption of the git cache file at my local branch. I fixed it by writing the missing commit hash into that file. I got the right commit hash from the server and ran the following command locally:

cat .git/refs/remotes/origin/feature/mybranch \
echo 1edf9668426de67ab764af138a98342787dc87fe \
>> .git/refs/remotes/origin/feature/mybranch

You could use the TIMEDIFF() and the TIME_TO_SEC() functions as follows:

SELECT TIME_TO_SEC(TIMEDIFF('2010-08-20 12:01:00', '2010-08-20 12:00:00')) diff;
+------+
| diff |
+------+
|   60 |
+------+
1 row in set (0.00 sec)

You could also use the UNIX_TIMESTAMP() function as @Amber suggested in an other answer:

SELECT UNIX_TIMESTAMP('2010-08-20 12:01:00') - 
       UNIX_TIMESTAMP('2010-08-20 12:00:00') diff;
+------+
| diff |
+------+
|   60 |
+------+
1 row in set (0.00 sec)

If you are using the TIMESTAMP data type, I guess that the UNIX_TIMESTAMP() solution would be slightly faster, since TIMESTAMP values are already stored as an integer representing the number of seconds since the epoch (Source). Quoting the docs:

When UNIX_TIMESTAMP() is used on a TIMESTAMP column, the function returns the internal timestamp value directly, with no implicit “string-to-Unix-timestamp” conversion.

Keep in mind that TIMEDIFF() return data type of TIME. TIME values may range from '-838:59:59' to '838:59:59' (roughly 34.96 days)

What about scipy.interpolate.splrep (with degree 1 and no smoothing):

>> tck = scipy.interpolate.splrep([1, 2, 3, 4, 5], [1, 4, 9, 16, 25], k=1, s=0)
>> scipy.interpolate.splev(6, tck)
34.0

It seems to do what you want, since 34 = 25 + (25 - 16).

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

Change your directive definition from app.module to app.directive. Apart from that everything looks fine. Btw, very rarely do you have to inject a service into a directive. If you are injecting a service ( which usually is a data source or model ) into your directive ( which is kind of part of a view ), you are creating a direct coupling between your view and model. You need to separate them out by wiring them together using a controller.

It does work fine. I am not sure what you are doing which is wrong. Here is a plunk of it working.

In 3 words: inline-block is better.

Inline Block

The only drawback to the display: inline-block approach is that in IE7 and below an element can only be displayed inline-block if it was already inline by default. What this means is that instead of using a <div> element you have to use a <span> element. It's not really a huge drawback at all because semantically a <div> is for dividing the page while a <span> is just for covering a span of a page, so there's not a huge semantic difference. A huge benefit of display:inline-block is that when other developers are maintaining your code at a later point, it is much more obvious what display:inline-block and text-align:right is trying to accomplish than a float:left or float:right statement. My favorite benefit of the inline-block approach is that it's easy to use vertical-align: middle, line-height and text-align: center to perfectly center the elements, in a way that is intuitive. I found a great blog post on how to implement cross-browser inline-block, on the Mozilla blog. Here is the browser compatibility.

Float

The reason that using the float method is not suited for layout of your page is because the float CSS property was originally intended only to have text wrap around an image (magazine style) and is, by design, not best suited for general page layout purposes. When changing floated elements later, sometimes you will have positioning issues because they are not in the page flow. Another disadvantage is that it generally requires a clearfix otherwise it may break aspects of the page. The clearfix requires adding an element after the floated elements to stop their parent from collapsing around them which crosses the semantic line between separating style from content and is thus an anti-pattern in web development.

Any white space problems mentioned in the link above could easily be fixed with the white-space CSS property.

Edit:

SitePoint is a very credible source for web design advice and they seem to have the same opinion that I do:

If you’re new to CSS layouts, you’d be forgiven for thinking that using CSS floats in imaginative ways is the height of skill. If you have consumed as many CSS layout tutorials as you can find, you might suppose that mastering floats is a rite of passage. You’ll be dazzled by the ingenuity, astounded by the complexity, and you’ll gain a sense of achievement when you finally understand how floats work.

Don’t be fooled. You’re being brainwashed.

2015 Update - Flexbox is a good alternative for modern browsers:

.container {
  display: flex; /* or inline-flex */
}

.item {
  flex: none | [ <'flex-grow'> <'flex-shrink'>? || <'flex-basis'> ]
}

More info

Dec 21, 2016 Update

Bootstrap 4 is removing support for IE9, and thus is getting rid of floats from rows and going full Flexbox.

Pull request #21389

An alternative solution uses the stash:

Before:

~/dev/gitpro $git stash list

~/dev/gitpro $git log --oneline -3

* 7049dd5 (HEAD -> master) c111
* 3f1fa3d c222
* 0a0f6c4 c333

1. git reset head~1 <--- head shifted one back to c222; working still contains c111 changes
2. git stash push -m "commit 111" <--- staging/working (containing c111 changes) stashed; staging/working rolled back to revised head (containing c222 changes)
3. git reset head~1 <--- head shifted one back to c333; working still contains c222 changes
4. git stash push -m "commit 222" <--- staging/working (containing c222 changes) stashed; staging/working rolled back to revised head (containing c333 changes)
5. git stash pop stash@{1} <--- oldest stash entry with c111 changes removed & applied to staging/working
6. git commit -am "commit 111" <-- new commit with c111's changes becomes new head

note you cannot run 'git stash pop' without specifying the stash@{1} entry. The stash is a LIFO stack -- not FIFO -- so that would incorrectly pop the stash@{0} entry with c222's changes (instead of stash@{1} with c111's changes).

note if there are conflicting chunks between commits 111 and 222, then you'll be forced to resolve them when attempting to pop. (This would be the case if you went with an alternative rebase solution as well.)

After:

~/dev/gitpro $git stash list

stash@{0}: On master: c222

~/dev/gitpro $git log -2 --oneline

* edbd9e8 (HEAD -> master) c111

public string MakeRelativePath(string workingDirectory, string fullPath)
{
    string result = string.Empty;
    int offset;

    // this is the easy case.  The file is inside of the working directory.
    if( fullPath.StartsWith(workingDirectory) )
    {
        return fullPath.Substring(workingDirectory.Length + 1);
    }

    // the hard case has to back out of the working directory
    string[] baseDirs = workingDirectory.Split(new char[] { ':', '\\', '/' });
    string[] fileDirs = fullPath.Split(new char[] { ':', '\\', '/' });

    // if we failed to split (empty strings?) or the drive letter does not match
    if( baseDirs.Length <= 0 || fileDirs.Length <= 0 || baseDirs[0] != fileDirs[0] )
    {
        // can't create a relative path between separate harddrives/partitions.
        return fullPath;
    }

    // skip all leading directories that match
    for (offset = 1; offset < baseDirs.Length; offset++)
    {
        if (baseDirs[offset] != fileDirs[offset])
            break;
    }

    // back out of the working directory
    for (int i = 0; i < (baseDirs.Length - offset); i++)
    {
        result += "..\\";
    }

    // step into the file path
    for (int i = offset; i < fileDirs.Length-1; i++)
    {
        result += fileDirs[i] + "\\";
    }

    // append the file
    result += fileDirs[fileDirs.Length - 1];

    return result;
}

This code is probably not bullet-proof but this is what I came up with. It's a little more robust. It takes two paths and returns path B as relative to path A.

example:

MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\junk\\readme.txt")
//returns: "..\\..\\junk\\readme.txt"

MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\foo\\bar\\docs\\readme.txt")
//returns: "docs\\readme.txt"

For external link simply use an achor in place of Link:

Here is an other solution, largely inspired by the one by @fredoverflow.

/**
 * Return hexadecimal representation of the input binary sequence
 */
std::string hexitize(const std::vector<char>& input, const char* const digits = "0123456789ABCDEF")
{
    std::ostringstream output;

    for (unsigned char gap = 0, beg = input[gap]; gap < input.length(); beg = input[++gap])
        output << digits[beg >> 4] << digits[beg & 15];

    return output.str();
}

Length was required parameter in the intended usage.

You might also, like me, have installed php-cgi prior to installing Apache and when doing so it doesn't set up Apache properly to run PHP, removing PHP entirely and reinstalling seemed to fix my problem.

I cross that situation by replacing all androidx.* to appropiate package name.

change your line

implementation 'androidx.appcompat:appcompat:1.0.0-alpha3'
implementation 'androidx.constraintlayout:constraintlayout:1.1.1'

androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'

to

implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
implementation 'com.android.support.constraint:constraint-layout:1.1.1'

The shortest way without declaring the variable is with Type Hints :

s$ =  123   ' s = "123"
i% = "123"  ' i =  123

This will not compile with Option Explicit. The types will not be Variant but String and Integer

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

void foo(int a)
void foo(int a, float b)

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

class Parent {
    void foo(double d) {
        // do something
    }
}

class Child extends Parent {

    @Override
    void foo(double d){
        // this method is overridden.  
    }
}

You should not just try to pause 5 seconds in javascript. It doesn't work that way. You can schedule a function of code to run 5 seconds from now, but you have to put the code that you want to run later into a function and the rest of your code after that function will continue to run immediately.

For example:

function stateChange(newState) {
    setTimeout(function(){
        if(newState == -1){alert('VIDEO HAS STOPPED');}
    }, 5000);
}

But, if you have code like this:

stateChange(-1);
console.log("Hello");

The console.log() statement will run immediately. It will not wait until after the timeout fires in the stateChange() function. You cannot just pause javascript execution for a predetermined amount of time.

Instead, any code that you want to run delays must be inside the setTimeout() callback function (or called from that function).

If you did try to "pause" by looping, then you'd essentially "hang" the Javascript interpreter for a period of time. Because Javascript runs your code in only a single thread, when you're looping nothing else can run (no other event handlers can get called). So, looping waiting for some variable to change will never work because no other code can run to change that variable.

WOFF 2.0, based on the Brotli compression algorithm and other improvements over WOFF 1.0 giving more than 30 % reduction in file size, is supported in Chrome, Opera, and Firefox.

http://en.wikipedia.org/wiki/Web_Open_Font_Format http://en.wikipedia.org/wiki/Brotli

http://sth.name/2014/09/03/Speed-up-webfonts/ has an example on how to use it.

Basically you add a src url to the woff2 file and specify the woff2 format. It is important to have this before the woff-format: the browser will use the first format that it supports.

I don't know if it is help. Create an AVD for a tablet-type device: Set the target to "Android 3.0" and the skin to "WXGA" (the default skin). You can check this site. http://developer.android.com/guide/practices/optimizing-for-3.0.html

Scripts are raw java embedded in the page code, and if you declare variables in your scripts, then they become local variables embedded in the page.

In contrast, JSTL works entirely with scoped attributes, either at page, request or session scope. You need to rework your scriptlet to fish test out as an attribute:

<c:set var="test" value="test1"/>
<%
  String resp = "abc";
  String test = pageContext.getAttribute("test");
  resp = resp + test;
  pageContext.setAttribute("resp", resp);
%>
<c:out value="${resp}"/>

If you look at the docs for <c:set>, you'll see you can specify scope as page, request or session, and it defaults to page.

Better yet, don't use scriptlets at all: they make the baby jesus cry.

You don't need the separate fill item. In fact, it's invalid. You just have to add a solid block to the shape. The subsequent stroke draws on top of the solid:

<shape 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">

    <corners android:radius="5dp" />
    <solid android:color="@android:color/white" />
    <stroke
        android:width="1dip"
        android:color="@color/bggrey" />
</shape>

You also don't need the layer-list if you only have one shape.

In the initialization chunk I define a function

pagebreak <- function() {
  if(knitr::is_latex_output())

  else
    return('<div style="page-break-before: always;" />')
}

In the markdown part where I want to insert a page break, I type

`r pagebreak()`

I put

<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>

I could not believe it did work!!

The following module allows you to group Django models and still work with a QuerySet in the result: https://github.com/kako-nawao/django-group-by

For example:

from django_group_by import GroupByMixin

class BookQuerySet(QuerySet, GroupByMixin):
    pass

class Book(Model):
    title = TextField(...)
    author = ForeignKey(User, ...)
    shop = ForeignKey(Shop, ...)
    price = DecimalField(...)

class GroupedBookListView(PaginationMixin, ListView):
    template_name = 'book/books.html'
    model = Book
    paginate_by = 100

    def get_queryset(self):
        return Book.objects.group_by('title', 'author').annotate(
            shop_count=Count('shop'), price_avg=Avg('price')).order_by(
            'name', 'author').distinct()

    def get_context_data(self, **kwargs):
        return super().get_context_data(total_count=self.get_queryset().count(), **kwargs)

'book/books.html'

<ul>
{% for book in object_list %}
    <li>
        <h2>{{ book.title }}</td>
        <p>{{ book.author.last_name }}, {{ book.author.first_name }}</p>
        <p>{{ book.shop_count }}</p>
        <p>{{ book.price_avg }}</p>
    </li>
{% endfor %}
</ul>

The difference to the annotate/aggregate basic Django queries is the use of the attributes of a related field, e.g. book.author.last_name.

If you need the PKs of the instances that have been grouped together, add the following annotation:

.annotate(pks=ArrayAgg('id'))

NOTE: ArrayAgg is a Postgres specific function, available from Django 1.9 onwards: https://docs.djangoproject.com/en/1.10/ref/contrib/postgres/aggregates/#arrayagg

From Which comparator, test, bracket, or double bracket, is fastest? (http://bashcurescancer.com)

The double bracket is a “compound command” where as test and the single bracket are shell built-ins (and in actuality are the same command). Thus, the single bracket and double bracket execute different code.

The test and single bracket are the most portable as they exist as separate and external commands. However, if your using any remotely modern version of BASH, the double bracket is supported.

LocalDate ld ....;
LocalDateTime ldtime ...;

ld.isEqual(LocalDate.from(ldtime));

I collected several of the solutions mentioned in other answers and in comments, then ran a speed test. not set(a).isdisjoint(b) turned out the be the fastest, it also did not slowdown much when the result was False.

Each of the three runs tests a small sample of the possible configurations of a and b. The times are in microseconds.

There is a very good case for using "adding existing file links" when reusing code across projects, and that is when you need to reference and support different versions of dependent libraries.

Making multiple assemblies with references to different external assemblies isn't easy to do otherwise without duplicating your code, or utilizing tricks with source code control.

I believe that it's easiest to maintain one project for development and unit test, then to create 'build' projects using existing file links when you need to create the assemblies which reference different versions of those external assemblies.

That entity is converted to the char it represents when the browser renders the page. JS (jQuery) reads the rendered page, thus it will not encounter such a text sequence. The only way it could encounter such a thing is if you're double encoding entities.

The api is fairly easy to use.

// Lookup the dns, if the ip exists.
 if (!ip.isEmpty()) {
     InetAddress inetAddress = InetAddress.getByName(ip);
     dns = inetAddress.getCanonicalHostName(); 
 }

In short, yes.

Suppose we are on a 32-bit machine.

If it is little endian, the x in the memory will be something like:

       higher memory
          ----->
    +----+----+----+----+
    |0x01|0x00|0x00|0x00|
    +----+----+----+----+
    A
    |
   &x

so (char*)(&x) == 1, and *y+48 == '1'.

If it is big endian, it will be:

    +----+----+----+----+
    |0x00|0x00|0x00|0x01|
    +----+----+----+----+
    A
    |
   &x

so this one will be '0'.

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:

@keyframes changewidth {
  from {
    transform: scaleX(1);
  }

  to {
    transform: scaleX(2);
  }
}

div {
  animation-duration: 0.1s;
  animation-name: changewidth;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108

To Start Tomcat7 Service :

• Open cmd, go to bin directory within "Apache Tomcat 7" folder. You will see some this like C:\..\bin>

• Enter above command to start the service: C:\..\bin>service.bat install. The service will get started now.

• Enter above command to start tomcat7w monitory service. If you have issue with starting the tomcat7 service then remove the service with command : C:\..\bin>tomcat7 //DS//Tomcat7

• Now the service will no longer exist. Try the install command again, now the service will get installed and started: C:\..\bin>tomcat7w \\MS\tomcat7w

• You will see the tomcat 7 icon in the system tray. Now, the tomcat7 service and tomcat7w will start automatically when the windows get start.

This error is also related with a cache issue.

I had the same problem and it was solved just cleaning and building the solution again.

You're missing quotes around the first value, it should be

INSERT INTO LOCATION VALUES('PQ95VM', 'HAPPY_STREET', 'FRANCE');

Incidentally, you'd be well-advised to specify the column names explicitly in the INSERT, for reasons of readability, maintainability and robustness, i.e.

INSERT INTO LOCATION (POSTCODE, STREET_NAME, CITY) VALUES ('PQ95VM', 'HAPPY_STREET', 'FRANCE');

This can happen when your plot panel in RStudio is too small for the margins of the plot you are trying to create. Try making expanding it and then run your code again.

RStudio UI causes an error when the plot panel is too small to display the chart:

Simply expanding the plot panel fixes the bug and displays the chart:

When you open a file, the system points to the beginning of the file. Any read or write you do will happen from the beginning. A seek() operation moves that pointer to some other part of the file so you can read or write at that place.

So, if you want to read the whole file but skip the first 20 bytes, open the file, seek(20) to move to where you want to start reading, then continue with reading the file.

Or say you want to read every 10th byte, you could write a loop that does seek(9, 1) (moves 9 bytes forward relative to the current positions), read(1) (reads one byte), repeat.

First method (internal function)

The best way I have tried before is to use urlencode(). Keep in mind, don't use it for the whole url; instead, use it only for the needed parts. For example, a request that has two 'text-fa' and 'text-en' fields and they contain a Persian and an English text, respectively, you might only need to encode the Persian text, not the English one.

Second Method (using cURL function)

However, there are better ways if the range of characters have to be encoded is more limited. One of these ways is using CURLOPT_ENCODING, by passing it to curl_setopt():

curl_setopt($ch, CURLOPT_ENCODING, "");

Incrementing dates can be accomplished using timedelta objects:

import datetime

datetime.datetime.now() + datetime.timedelta(days=1)

Look up timedelta objects in the Python docs: http://docs.python.org/library/datetime.html

In Python it is easier to ask for forgiveness than permission. Don't sweat the nested exception handling.

(Besides, has* almost always uses exceptions under the cover anyway.)

Funny enough, a same problem I just met, and I get this work in following way:

combining with linux command ln , we can make thing a lot simper:

1. cd Proj/Client
2. ln -s ../Common ./

3. cd Proj/Server
4. ln -s ../Common ./

And, now if you want to import some_stuff from file: Proj/Common/Common.py into your file: Proj/Client/Client.py, just like this:

# in Proj/Client/Client.py
from Common.Common import some_stuff

And, the same applies to Proj/Server, Also works for setup.py process, a same question discussed here, hope it helps !

I have used Derby and i really hate it's data type conversion functions, especially date/time functions. (Number Type)<--> Varchar conversion it's a pain.

So that if you plan use data type conversions in your DB statements consider the use of othe embedded DB, i learn it too late.

The appropriate way to read text files in Cocoa/Objective-C is documented in Apple's String programming guide. The section for reading and writing files should be just what you're after. PS: What's a "line"? Two sections of a string separated by "\n"? Or "\r"? Or "\r\n"? Or maybe you're actually after paragraphs? The previously mentioned guide also includes a section on splitting a string into lines or paragraphs. (This section is called "Paragraphs and Line Breaks", and is linked to in the left-hand-side menu of the page I pointed to above. Unfortunately this site doesn't allow me to post more than one URL as I'm not a trustworthy user yet.)

To paraphrase Knuth: premature optimisation is the root of all evil. Don't simply assume that "reading the whole file into memory" is slow. Have you benchmarked it? Do you know that it actually reads the whole file into memory? Maybe it simply returns a proxy object and keeps reading behind the scenes as you consume the string? (Disclaimer: I have no idea if NSString actually does this. It conceivably could.) The point is: first go with the documented way of doing things. Then, if benchmarks show that this doesn't have the performance you desire, optimise.

One issue with REPLACE will be where city names contain the district name. You can use something like.

SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM   dbo.tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004' 

There are several ways I can think of to do this.

Use a callback:

 function FunctInit(someVarible){
      //init and fill screen
      AndroidCallGetResult();  // Enables Android button.
 }

 function getResult(){ // Called from Android button only after button is enabled
      //return some variables
 }

Use a Timeout (this would probably be my preference):

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      if (inited) {
           //return some variables
      } else {
           setTimeout(getResult, 250);
      }
 }

Wait for the initialization to occur:

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      var a = 1;
      do { a=1; }
      while(!inited);
      //return some variables
 }

You will figure out that setOnPageChangeListener is deprecated, use addOnPageChangeListener, as below:

ViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {
       if(position == 1){  // if you want the second page, for example
           //Your code here
       }
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
});

Most of them already answered to the point. Just as an additional note (based on my understanding and experimenting but not from a documented source), the statement

== if the objects referred to by the variables are equal

from above answers should be read as

== if the objects referred to by the variables are equal and objects belonging to the same type/class

. I arrived at this conclusion based on the below test:

list1 = [1,2,3,4]
tuple1 = (1,2,3,4)

print(list1)
print(tuple1)
print(id(list1))
print(id(tuple1))

print(list1 == tuple1)
print(list1 is tuple1)

Here the contents of the list and tuple are same but the type/class are different.

You can also do this if you want to play around with pandas. However, I like punchagan's way.

# replicating your dataframe
lake = pd.DataFrame({'co tp': ['DE Lake', 'Forest', 'FR Lake', 'Forest'], 
                 'area': [10, 20, 30, 40], 
                 'count': [7, 5, 2, 3]})
lake.set_index('co tp', inplace=True)

# to get key value using pandas
area_dict = lake.set_index('area').T.to_dict('records')[0]
print(area_dict)

output: {10: 7, 20: 5, 30: 2, 40: 3}

Some great news! Since version 3.6 the cPython implementation has preserved the insertion order of dictionaries (https://mail.python.org/pipermail/python-dev/2016-September/146327.html). This means that the json library is now order preserving by default. Observe the difference in behaviour between python 3.5 and 3.6. The code:

import json
data = json.loads('{"foo":1, "bar":2, "fiddle":{"bar":2, "foo":1}}')
print(json.dumps(data, indent=4))

In py3.5 the resulting order is undefined:

{
    "fiddle": {
        "bar": 2,
        "foo": 1
    },
    "bar": 2,
    "foo": 1
}

In the cPython implementation of python 3.6:

{
    "foo": 1,
    "bar": 2,
    "fiddle": {
        "bar": 2,
        "foo": 1
    }
}

The really great news is that this has become a language specification as of python 3.7 (as opposed to an implementation detail of cPython 3.6+): https://mail.python.org/pipermail/python-dev/2017-December/151283.html

So the answer to your question now becomes: upgrade to python 3.6! :)

It will be easier to do using decode.

SELECT
  status,
    decode ( status, 'a1','Active',
                     'a2','Active',
                     'a3','Active',
                     'i','Inactive',
                     't','Terminated',
                     'Default')STATUSTEXT
FROM STATUS

On Windows, you can use the following command to find out the defaults on the system where your applications runs.

java -XX:+PrintFlagsFinal -version | findstr HeapSize

Look for the options MaxHeapSize (for -Xmx) and InitialHeapSize for -Xms.

On a Unix/Linux system, you can do

java -XX:+PrintFlagsFinal -version | grep HeapSize

I believe the resulting output is in bytes.

For whoever is using Kotlin, honestly the by far easiest way to iterate over a SparseArray is: Use the Kotlin extension from Anko or Android KTX! (credit to Yazazzello for pointing out Android KTX)

Simply call forEach { i, item -> }

A predicate in T is a delegate that takes in a T and returns a bool. List<T>.RemoveAll will remove all elements in a list where calling the predicate returns true. The easiest way to supply a simple predicate is usually a lambda expression, but you can also use anonymous methods or actual methods.

{
    List<Vehicle> vehicles;
    // Using a lambda
    vehicles.RemoveAll(vehicle => vehicle.EnquiryID == 123);
    // Using an equivalent anonymous method
    vehicles.RemoveAll(delegate(Vehicle vehicle)
    {
        return vehicle.EnquiryID == 123;
    });
    // Using an equivalent actual method
    vehicles.RemoveAll(VehiclePredicate);
}

private static bool VehiclePredicate(Vehicle vehicle)
{
    return vehicle.EnquiryID == 123;
}

In Angular (currently on Angular-6) .subscribe() is a method on the Observable type. The Observable type is a utility that asynchronously or synchronously streams data to a variety of components or services that have subscribed to the observable.

The observable is an implementation/abstraction over the promise chain and will be a part of ES7 as a proposed and very supported feature. In Angular it is used internally due to rxjs being a development dependency.

An observable itself can be thought of as a stream of data coming from a source, in Angular this source is an API-endpoint, a service, a database or another observable. But the power it has is that it's not expecting a single response. It can have one or many values that are returned.

Link to rxjs for observable/subscribe docs here: https://rxjs-dev.firebaseapp.com/api/index/class/Observable#subscribe-

Subscribe takes 3 methods as parameters each are functions:

• next: For each item being emitted by the observable perform this function
• error: If somewhere in the stream an error is found, do this method
• complete: Once all items are complete from the stream, do this method

Within each of these, there is the potentional to pipe (or chain) other utilities called operators onto the results to change the form or perform some layered logic.

In the simple example above:

.subscribe(hero => this.hero = hero); basically says on this observable take the hero being emitted and set it to this.hero.

Adding this answer to give more context to Observables based off the documentation and my understanding.

If you limit yourself to repeating either a 0 or a space you can do:

For spaces:

printf("%*s", count, "");

For zeros:

printf("%0*d", count, 0);

This is the solution for me

File currentDir = new File("");

If you are using Bearing Token Auth, the above samples do not return an Application User.

Instead, use this:

ClaimsPrincipal currentUser = this.User;
var currentUserName = currentUser.FindFirst(ClaimTypes.NameIdentifier).Value;
ApplicationUser user = await _userManager.FindByNameAsync(currentUserName);

This works in apsnetcore 2.0. Have not tried in earlier versions.

Just add:

import os

in the beginning, before:

from settings import PROJECT_ROOT

This will import the python's module os, which apparently is used later in the code of your module without being imported.

The port Node is trying to use can be already used by another program. In my case it was ntop, which I had recently installed. I had to open http://localhost:3000/ in a browser to realize it. Another way to find the process is given here.

• Adding some solution in Answer..**

This code has helped me to dock some executable in windows form. like NotePad, Excel, word, Acrobat reader n many more...

But it wont work for some applications. As sometimes when you start process of some application.... wait for idle time... and the try to get its mainWindowHandle.... till the time the main window handle becomes null.....

so I have done one trick to solve this

If you get main window handle as null... then search all the runnning processes on sytem and find you process ... then get the main hadle of the process and the set panel as its parent.

        ProcessStartInfo info = new ProcessStartInfo();
        info.FileName = "xxxxxxxxxxxx.exe";
        info.Arguments = "yyyyyyyyyy";
        info.UseShellExecute = true;
        info.CreateNoWindow = true;
        info.WindowStyle = ProcessWindowStyle.Maximized;
        info.RedirectStandardInput = false;
        info.RedirectStandardOutput = false;
        info.RedirectStandardError = false;

        System.Diagnostics.Process p = System.Diagnostics.Process.Start(info); 

        p.WaitForInputIdle();
        Thread.Sleep(3000);

        Process[] p1 ;
    if(p.MainWindowHandle == null)
    {
        List<String> arrString = new List<String>();
        foreach (Process p1 in Process.GetProcesses())
        {
            // Console.WriteLine(p1.MainWindowHandle);
            arrString.Add(Convert.ToString(p1.ProcessName));
        }
        p1 = Process.GetProcessesByName("xxxxxxxxxxxx");
        //p.WaitForInputIdle();
        Thread.Sleep(5000);
      SetParent(p1[0].MainWindowHandle, this.panel2.Handle);

    }
    else
    {
     SetParent(p.MainWindowHandle, this.panel2.Handle);
     }

I think somewhere in your codebase are you @Autowiring the concrete class ServiceImpl where you should be autowiring it's interface (presumably MyService).

npm install --silent

Seems to suppress the funding issue.

To hide scroll bar on Chrome, Firefox and IE you can use this:

.hide-scrollbar
{
    overflow: auto;
    -ms-overflow-style: none; /* IE 11 */
    scrollbar-width: none; /* Firefox 64 */
}

be sure, that if the declarations for the pipe are done in one module, while you are using the pipe inside another module, you should provide correct imports/declarations at the current module under which is the class where you are using the pipe. In my case that was the reason for the pipe miss

If you want to know the day of the week for your code to do something with it, DateTime.Now.DayOfWeek will do the job.

If you want to display the day of week to the user, DateTime.Now.ToString("dddd") will give you the localized day name, according to the current culture (MSDN info on the "dddd" format string).

How about simply:

select distinct c1, c2 from t

or

select c1, c2, count(*)
from t
group by c1, c2

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

The problem appears to be that the global symbol clear is already in use and your function doesn't succeed in overriding it. If you change that name to something else (I used blah), it works just fine:

Live: Version using clear which fails | Version using blah which works

<html>
<head>
    <title>lala</title>
</head>
<body>
    <h1 onmouseover="go('The dog is in its shed')" onmouseout="blah()">lalala</h1>
    <div id="goy"></div>
    <script type="text/javascript">
    function go(what) {
        document.getElementById("goy").innerHTML = what;
    }
    function blah() {
        document.getElementById("goy").innerHTML = "";
    }
    </script>
</body>
</html>

This is a great illustration of the fundamental principal: Avoid global variables wherever possible. The global namespace in browsers is incredibly crowded, and when conflicts occur, you get weird bugs like this.

A corollary to that is to not use old-style onxyz=... attributes to hook up event handlers, because they require globals. Instead, at least use code to hook things up: Live Copy

<html>
<head>
    <title>lala</title>
</head>
<body>
    <h1 id="the-header">lalala</h1>
    <div id="goy"></div>
    <script type="text/javascript">
      // Scoping function makes the declarations within
      // it *not* globals
      (function(){
        var header = document.getElementById("the-header");
        header.onmouseover = function() {
          go('The dog is in its shed');
        };
        header.onmouseout = clear;

        function go(what) {
          document.getElementById("goy").innerHTML = what;
        }
        function clear() {
          document.getElementById("goy").innerHTML = "";
        }
      })();
    </script>
</body>
</html>

...and even better, use DOM2's addEventListener (or attachEvent on IE8 and earlier) so you can have multiple handlers for an event on an element.

when you use const in the method signature (like your said: const char* foo() const;) you are telling the compiler that memory pointed to by this can't be changed by this method (which is foo here).

If you want to browse to a folder by default: For example "D:\Default_Folder" just initialise the "InitialFileName" attribute

Dim diaFolder As FileDialog

' Open the file dialog
Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
diaFolder.AllowMultiSelect = False
diaFolder.InitialFileName = "D:\Default_Folder"
diaFolder.Show

It's pretty simple.

            var oFile = document.getElementById("fileUpload").files[0]; // <input type="file" id="fileUpload" accept=".jpg,.png,.gif,.jpeg"/>

            if (oFile.size > 2097152) // 2 MiB for bytes.
            {
                alert("File size must under 2MiB!");
                return;
            }

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.

To debug, check server logs if possible. Firefox returns CORS errors in console for a whole range of reasons.

One of the reasons is also uMatrix (and I guess NoScript and similar too) plugin.

As answered before, it's currently still being considered but it has been dead in the water for a few years by now.

Building on the existing answers, here's the most concise manual version I can think of:

jsfiddle

function val<T>(valueSupplier: () => T): T {
  try { return valueSupplier(); } catch (err) { return undefined; }
}

let obj1: { a?: { b?: string }} = { a: { b: 'c' } };
console.log(val(() => obj1.a.b)); // 'c'

obj1 = { a: {} };
console.log(val(() => obj1.a.b)); // undefined
console.log(val(() => obj1.a.b) || 'Nothing'); // 'Nothing'

obj1 = {};
console.log(val(() => obj1.a.b) || 'Nothing'); // 'Nothing'

obj1 = null;
console.log(val(() => obj1.a.b) || 'Nothing'); // 'Nothing'

It simply silently fails on missing property errors. It falls back to the standard syntax for determining default value, which can be omitted completely as well.

Although this works for simple cases, if you need more complex stuff such as calling a function and then access a property on the result, then any other errors are swallowed as well. Bad design.

In the above case, an optimized version of the other answer posted here is the better option:

jsfiddle

function o<T>(obj?: T, def: T = {} as T): T {
    return obj || def;
}

let obj1: { a?: { b?: string }} = { a: { b: 'c' } };
console.log(o(o(o(obj1).a)).b); // 'c'

obj1 = { a: {} };
console.log(o(o(o(obj1).a)).b); // undefined
console.log(o(o(o(obj1).a)).b || 'Nothing'); // 'Nothing'

obj1 = {};
console.log(o(o(o(obj1).a)).b || 'Nothing'); // 'Nothing'

obj1 = null;
console.log(o(o(o(obj1).a)).b || 'Nothing'); // 'Nothing'

A more complex example:

o(foo(), []).map((n) => n.id)

You can also go the other way and use something like Lodash' _.get(). It is concise, but the compiler won't be able to judge the validity of the properties used:

console.log(_.get(obj1, 'a.b.c'));

This is difficult with worksheet functions because dates in excel are simply formatted numbers - only CELL function lets you investigate the format of a cell (and you can't apply that to a range, so a helper column would be required).......or, if you only have dates and blanks.....or dates and text then it would be sufficient to use COUNT function, i.e.

=COUNT(range)

That counts numbers so it won't be adequate if you want to distinguish dates from numbers. If you do then the number range could be utilised, e.g. if you have numbers in a range and dates but the numbers will all be lower than 10,000 and the dates will all be relatively recent then you could use this version to exclude the numbers

=COUNTIF(range,">10000")

Django 3.0

here is link how to customize error views

here is link how to render a view

in the urls.py (the main one, in project folder), put:

handler404 = 'my_app_name.views.custom_page_not_found_view'
handler500 = 'my_app_name.views.custom_error_view'
handler403 = 'my_app_name.views.custom_permission_denied_view'
handler400 = 'my_app_name.views.custom_bad_request_view'

and in that app (my_app_name) put in the views.py:

def custom_page_not_found_view(request, exception):
    return render(request, "errors/404.html", {})

def custom_error_view(request, exception=None):
    return render(request, "errors/500.html", {})

def custom_permission_denied_view(request, exception=None):
    return render(request, "errors/403.html", {})

def custom_bad_request_view(request, exception=None):
    return render(request, "errors/400.html", {})

NOTE: error/404.html is the path if you place your files into the projects (not the apps) template foldertemplates/errors/404.html so please place the files where you want and write the right path.

NOTE 2: After page reload, if you still see the old template, change in settings.py DEBUG=True, save it, and then again to False (to restart the server and collect the new files).

To check if a path is an existing file:

os.path.isfile(path)

Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.

findIndex was added in 1.8:

index = _.findIndex(tv, function(voteItem) { return voteItem.id == voteID })

See: http://underscorejs.org/#findIndex

Alternatively, this also works, if you don't mind making another temporary list:

index = _.indexOf(_.pluck(tv, 'id'), voteId);

See: http://underscorejs.org/#pluck

Using reshape function:

reshape(dat1, idvar = "name", timevar = "numbers", direction = "wide")

<form name="add" method="post">
     <p>Age:</p>
     <select name="age">
        <option value="1_sre">23</option>
        <option value="2_sam">24</option>
        <option value="5_john">25</option>
     </select>
     <input type="submit" name="submit"/>
</form>

You will have the selected value in $_POST['age'], e.g. 1_sre. Then you will be able to split the value and get the 'stud_name'.

$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];

As answered by Magus :

the full path must me specified

Abstract states can be used to add a prefix to all child state urls. But note that abstract still needs a ui-view for its children to populate. To do so you can simply add it inline.

.state('app', {
   url: "/app",
   abstract: true,
   template: '<ui-view/>'
})

For more information see documentation : https://github.com/angular-ui/ui-router/wiki/Nested-States-%26-Nested-Views

The problem is actually that you need to double-escape backslashes in the replacement string. You see, "\\/" (as I'm sure you know) means the replacement string is \/, and (as you probably don't know) the replacement string \/ actually just inserts /, because Java is weird, and gives \ a special meaning in the replacement string. (It's supposedly so that \$ will be a literal dollar sign, but I think the real reason is that they wanted to mess with people. Other languages don't do it this way.) So you have to write either:

"Hello/You/There".replaceAll("/", "\\\\/");

or:

"Hello/You/There".replaceAll("/", Matcher.quoteReplacement("\\/"));

(Using java.util.regex.Matcher.quoteReplacement(String).)

You can view the source of the file up to a particular commit by appending ?until=<sha-of-commit> in the URL (after the file name).

SELECT *
   FROM   my_table
   WHERE  substr(my_field,1,5) = "abcde";

Are u sure u want to remove only last character. What if the user press backspace from the middle of the word.. Its better to get the value from the field and replace the divs html. On keyup

$("#div").html($("#input").val());

When converting an older project to .NET Core, most of the information that was in the AssemblyInfo.cs can now be set on the project itself. Open the project properties and select the Package tab to see the new settings.

The Eric L. Anderson's post "Duplicate ‘System.Reflection.AssemblyCompanyAttribute’ attribute" describes 3 options :

• remove the conflicting items from the AssemblyInfo.cs file,
• completely delete the file or
• disable GenerateAssemblyInfo (as suggested in another answer by Serge Semenov)

set datestr=%date%
set result=%datestr:/=-%
@echo %result%
pause

for i in $(seq 1 $END); do echo $i; done

edit: I prefer seq over the other methods because I can actually remember it ;)

use a temporary scan.nextLine(); this will consume the \n character

My problem was using cursor: 'pointer' mistakenly instead of cursor: pointer. So, make sure you are not adding single or double quotes around pointer.

I have such problem within the app, which access to SQLite from 2 connections - one was read-only and second for writing and reading. It looks like that read-only connection blocked writing from second connection. Finally, it is turns out that it is required to finalize or, at least, reset prepared statements IMMEDIATELY after use. Until prepared statement is opened, it caused to database was blocked for writing.

DON'T FORGET CALL:

sqlite_reset(xxx);

or

sqlite_finalize(xxx);

Strip won't work. It only removes leading and trailing instances, not everything in between: http://docs.python.org/2/library/stdtypes.html#str.strip

Having fun with filter:

import string
asking = "hello! what's your name?"
predicate = lambda x:x not in string.punctuation
filter(predicate, asking)

Like SplinterReality said: There's no reason not to use Dijkstra's algorithm here.

The code below I nicked from here and modified it to solve the example in the question.

import java.util.PriorityQueue;
import java.util.List;
import java.util.ArrayList;
import java.util.Collections;

class Vertex implements Comparable<Vertex>
{
    public final String name;
    public Edge[] adjacencies;
    public double minDistance = Double.POSITIVE_INFINITY;
    public Vertex previous;
    public Vertex(String argName) { name = argName; }
    public String toString() { return name; }
    public int compareTo(Vertex other)
    {
        return Double.compare(minDistance, other.minDistance);
    }

}


class Edge
{
    public final Vertex target;
    public final double weight;
    public Edge(Vertex argTarget, double argWeight)
    { target = argTarget; weight = argWeight; }
}

public class Dijkstra
{
    public static void computePaths(Vertex source)
    {
        source.minDistance = 0.;
        PriorityQueue<Vertex> vertexQueue = new PriorityQueue<Vertex>();
        vertexQueue.add(source);

        while (!vertexQueue.isEmpty()) {
            Vertex u = vertexQueue.poll();

            // Visit each edge exiting u
            for (Edge e : u.adjacencies)
            {
                Vertex v = e.target;
                double weight = e.weight;
                double distanceThroughU = u.minDistance + weight;
                if (distanceThroughU < v.minDistance) {
                    vertexQueue.remove(v);

                    v.minDistance = distanceThroughU ;
                    v.previous = u;
                    vertexQueue.add(v);
                }
            }
        }
    }

    public static List<Vertex> getShortestPathTo(Vertex target)
    {
        List<Vertex> path = new ArrayList<Vertex>();
        for (Vertex vertex = target; vertex != null; vertex = vertex.previous)
            path.add(vertex);

        Collections.reverse(path);
        return path;
    }

    public static void main(String[] args)
    {
        // mark all the vertices 
        Vertex A = new Vertex("A");
        Vertex B = new Vertex("B");
        Vertex D = new Vertex("D");
        Vertex F = new Vertex("F");
        Vertex K = new Vertex("K");
        Vertex J = new Vertex("J");
        Vertex M = new Vertex("M");
        Vertex O = new Vertex("O");
        Vertex P = new Vertex("P");
        Vertex R = new Vertex("R");
        Vertex Z = new Vertex("Z");

        // set the edges and weight
        A.adjacencies = new Edge[]{ new Edge(M, 8) };
        B.adjacencies = new Edge[]{ new Edge(D, 11) };
        D.adjacencies = new Edge[]{ new Edge(B, 11) };
        F.adjacencies = new Edge[]{ new Edge(K, 23) };
        K.adjacencies = new Edge[]{ new Edge(O, 40) };
        J.adjacencies = new Edge[]{ new Edge(K, 25) };
        M.adjacencies = new Edge[]{ new Edge(R, 8) };
        O.adjacencies = new Edge[]{ new Edge(K, 40) };
        P.adjacencies = new Edge[]{ new Edge(Z, 18) };
        R.adjacencies = new Edge[]{ new Edge(P, 15) };
        Z.adjacencies = new Edge[]{ new Edge(P, 18) };


        computePaths(A); // run Dijkstra
        System.out.println("Distance to " + Z + ": " + Z.minDistance);
        List<Vertex> path = getShortestPathTo(Z);
        System.out.println("Path: " + path);
    }
}

The code above produces:

Distance to Z: 49.0
Path: [A, M, R, P, Z]

Cookies are passed as HTTP headers, both in the request (client -> server), and in the response (server -> client).

Below is the easiest way in case if Anaconda is already installed.

1) Under "Files", there is an option called,"Upload".

2) Click on "Upload" button and it asks for the path of the file and select the file and click on upload button present beside the file.

None of these seemed to work for me:

@ECHO OFF

REM 1. Initialize our counter
SET /A "c=0"

REM Iterate through a dummy list. 
REM Notice how the counter is used: "CALL ECHO %%c%%" 
FOR /L %%i in (10,1,20) DO (

  REM 2. Increment counter
  SET /A "c+=1"

  REM 3. Print our counter "%c%" and some dummy data "%%i"
  CALL ECHO Line %%c%%: - Data: %%i
)

In the interest of creating a simple example that uses const...

const myRef = { foo: 'bar' };
const myVal = true;

function passes(r, v) {
  r.foo = 'baz';
  v = false;
}

passes(myRef, myVal);

console.log(myRef, myVal); // Object {foo: "baz"} true

Don't use the length parameter as it will not work with all browsers. The best way is to set a style on the input tag.

<input style="width:100px" />

just call your function inside the events.

load:

$(document).ready(function(){  // or  $(window).load(function(){
    topInViewport($(mydivname));
});

resize:

$(window).resize(function () {
    topInViewport($(mydivname));
});

scroll:

$(window).scroll(function () {
    topInViewport($(mydivname));
});

or bind all event in one function

$(window).on("load scroll resize",function(e){

I was getting HTTP Error 502.5 while trying to publish my .NET Core 2.0 API to AWS EB, and solved it by adding the following code to the .csproj:

  <PropertyGroup>
    <PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest>
  </PropertyGroup>

You can use following snippet to check Internet Connection.

It will useful both way that you can check which Type of NETWORK Connection is available so you can do your process on that way.

You just have to copy following class and paste directly in your package.

/**
 * @author Pratik Butani
 */
public class InternetConnection {

    /**
     * CHECK WHETHER INTERNET CONNECTION IS AVAILABLE OR NOT
     */
    public static boolean checkConnection(Context context) {
        final ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

        if (connMgr != null) {
            NetworkInfo activeNetworkInfo = connMgr.getActiveNetworkInfo();

            if (activeNetworkInfo != null) { // connected to the internet
                // connected to the mobile provider's data plan
                if (activeNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
                    // connected to wifi
                    return true;
                } else return activeNetworkInfo.getType() == ConnectivityManager.TYPE_MOBILE;
            }
        }
        return false;
    }
}

Now you can use like:

if (InternetConnection.checkConnection(context)) {
    // Its Available...
} else {
    // Not Available...
}

DON'T FORGET to TAKE Permission :) :)

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

You can modify based on your requirement.

Thank you.

I'd use np.all here, if you have an array a:

>>> np.all(a==0)

package com.tulu.ds;

public class EmailSecurity {
    public static void main(String[] args) {
        System.out.println(returnSecuredEmailID("[email protected]"));
    }
    private static String returnSecuredEmailID(String email){
        String str=email.substring(1, email.lastIndexOf("@")-1);
        return email.replaceAll(email.substring(1, email.lastIndexOf("@")-1),replacewith(str.length(),"*"));
    }
    private static String replacewith(int length,String replace) {
        String finalStr="";
        for(int i=0;i<length;i++){
            finalStr+=replace;
        }
        return finalStr;
    }   
}

I also made a solution, and it works quite well:
It uses jQuery and CSS

First, I made a quick CSS class, this can be embedded or in a seperate file.

<style type='text/css'>
    .Clicked {
        /*No Attributes*/
    }
</style>

Next, On the click event of a button within the form,add the CSS class to the button. If the button already has the CSS class, remove it. (We don't want two CSS classes [Just in case]).

    // Adds a CSS Class to the Button That Has Been Clicked.
    $("form :input[type='submit']").click(function () 
    {
        if ($(this).hasClass("Clicked"))
        {
            $(this).removeClass("Clicked");
        }
        $(this).addClass("Clicked");
    });

Now, test the button to see it has the CSS class, if the tested button doesn't have the CSS, then the other button will.

    // On Form Submit
    $("form").submit(function ()
    {
        // Test Which Button Has the Class
        if ($("input[name='name1']").hasClass("Clicked"))
        {
            // Button 'name1' has been clicked.
        }
        else
        {
           // Button 'name2' has been clicked.
        }
    });

Hope this helps! Cheers!

For a field separator of any number 2 through 5 or letter a or # or a space, where the separating character must be repeated at least 2 times and not more than 6 times, for example:

awk -F'[2-5a# ]{2,6}' ...

I am sure variations of this exist using ( ) and parameters

You have to specify the format (fmt) of you data in savetxt, in this case as a string (%s):

num.savetxt('test.txt', DAT, delimiter=" ", fmt="%s") 

The default format is a float, that is the reason it was expecting a float instead of a string and explains the error message.

`let element = document.queryselector('id or classname');

element.addeventlistiner('click',()=>{

do work })`

<button onclick="click()">click</click>

function click(){ do work };

New Way (Recommended):

Please take a look at this answer.

Old Way:

Supposing you're writing a program called myprog :

Put all your files in a directory like this

myproject/go/src/myprog/xxx.go

Then add myproject/go to GOPATH

And run

go install myprog

This way you'll be able to add other packages and programs in myproject/go/src if you want.

Reference : http://golang.org/doc/code.html

(this doc is always missed by newcomers, and often ill-understood at first. It should receive the greatest attention of the Go team IMO)

It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return statement. When the code goes down that path, the function ends with no value returned, and so returns None.

Updated: It sounds like your code looks like this:

def b(self, p, data): 
    current = p 
    if current.data == data: 
        return True 
    elif current.data == 1:
        return False 
    else: 
        self.b(current.next, data)

That else clause is your None path. You need to return the value that the recursive call returns:

    else:
        return self.b(current.next, data)

BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.

Combining the multiple ways browsers are using to store the user's language, you get this function :

const getNavigatorLanguage = () => {
  if (navigator.languages && navigator.languages.length) {
    return navigator.languages[0];
  } else {
    return navigator.userLanguage || navigator.language || navigator.browserLanguage || 'en';
  }
}

We first check the navigator.languages array for its first element.
Then we get either navigator.userLanguage or navigator.language.
If this fails we get navigator.browserLanguage.
Finally, we set it to 'en' if everything else failed.

And here's the sexy one-liner :

const getNavigatorLanguage = () => (navigator.languages && navigator.languages.length) ? navigator.languages[0] : navigator.userLanguage || navigator.language || navigator.browserLanguage || 'en';

sed '/^cdef$/r'<(
    echo "line1"
    echo "line2"
    echo "line3"
    echo "line4"
) -i -- input.txt

Is correct?

<script>
$( "#box" ).one( "click", function() {
  $( this ).css( "width", "+=200" );
});
</script>

dtList  = dtList.Where(s => !string.IsNullOrWhiteSpace(s)).Distinct().ToList()

I assumed empty string and whitespace are like null. If not you can use IsNullOrEmpty (allow whitespace), or s != null

This answer is similar to 17 but avoiding wrapper exception definition:

List test = new ArrayList();
        try {
            test.forEach(obj -> {

                //let say some functionality throws an exception
                try {
                    throw new IOException("test");
                }
                catch(Exception e) {
                    throw new RuntimeException(e);
                }
            });
        }
        catch (RuntimeException re) {

Why don't you use a combination of HTML/CSS instead? Image maps are obsolete.

This btw is Search Engine Optimised as well :)

Source code follows:

.image-map {
  background: url('https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png');
  width: 272px;
  height: 92px;
  display: block;
  position: relative;
  margin-top:10px;
  float: left;
}

.image-map > a.map {
  position: absolute;
  display: block;
  border: 1px solid green;
}

<div class="image-map">
    <a class="map" rel="G" style="top: 0px; left: 0px; width: 70px; height: 95px;" href="#"></a>
    <a class="map" rel="o" style="top: 0px; left: 70px; width: 50px; height: 95px" href="#"></a>
    <a class="map" rel="o" style="top: 0px; left: 120px; width: 50px; height: 95px" href="#"></a>
    <a class="map" rel="g" style="top: 0px; left: 170px; width: 40px; height: 95px" href="#"></a>
    <a class="map" rel="l" style="top: 0px; left: 210px; width: 20px; height: 95px" href="#"></a>
    <a class="map" rel="e" style="top: 0px; left: 230px; width: 40px; height: 95px" href="#"></a>
</div>

EDIT:

After the numerous negative points this answer has received I have to come back and say that I can clearly see that you don't agree with my answer, but I personally still believe that is a better option than image maps.

Sure it cannot do polygons, it might have issues on manual page zoom, but personally I feel image maps are obsolete although still on the html5 specification. (It makes make more sense nowadays to try and replicate them using html5 canvas instead)

However I guess the target audience for this question does not agree with me.

You could also check this Are HTML Image Maps still used? and see the most highly voted answer just for reference.

I like this method because it's easy to compare to any value in the object no matter how deep it's nested.

 while(i<myArray.length && myArray[i].data.value!==value){
  i++; 
}
// i now hows the index value for the match. 
 console.log("Index ->",i );

As long as your selector is actually working, I see nothing wrong with your code that checks the length of the array. That should do what you want. There are a lot of ways to clean up your code to be simpler and more readable. Here's a cleaned up version with notes about what I cleaned up.

var album_text = [];

$("input[name='album_text[]']").each(function() {
    var value = $(this).val();
    if (value) {
        album_text.push(value);
    }
});
if (album_text.length === 0) {
    $('#error_message').html("Error");
}

else {
  //send data
}

Some notes on what you were doing and what I changed.

1. $(this) is always a valid jQuery object so there's no reason to ever check if ($(this)). It may not have any DOM objects inside it, but you can check that with $(this).length if you need to, but that is not necessary here because the .each() loop wouldn't run if there were no items so $(this) inside your .each() loop will always be something.
2. It's inefficient to use $(this) multiple times in the same function. Much better to get it once into a local variable and then use it from that local variable.
3. It's recommended to initialize arrays with [] rather than new Array().
4. if (value) when value is expected to be a string will both protect from value == null, value == undefined and value == "" so you don't have to do if (value && (value != "")). You can just do: if (value) to check for all three empty conditions.
5. if (album_text.length === 0) will tell you if the array is empty as long as it is a valid, initialized array (which it is here).

What are you trying to do with this selector $("input[name='album_text[]']")?

Restart your IDE first and then run the following command in project folder from terminal

killall -9 dart

It worked for me. Hope it will help some of the guys facing the same problem.

Here are few steps that must be followed carefully

1. First of all make sure that the WAMP server is running if it is not running, start the server.
2. Enter the URL http://localhost/phpmyadmin/setup in address bar of your browser.

3. Create a folder named config inside C:\wamp\apps\phpmyadmin, the folder inside apps may have different name like phpmyadmin3.2.0.1

4. Return to your browser in phpmyadmin setup tab, and click New server.

5. Change the authentication type to ‘cookie’ and leave the username and password field empty but if you change the authentication type to ‘config’ enter the password for username root.

6. Click save

7. Again click save in configuration file option.
8. Now navigate to the config folder. Inside the folder there will be a file named config.inc.php. Copy the file and paste it out of the folder (if the file with same name is already there then override it) and finally delete the folder.
9. Now you are done. Try to connect the mysql server again and this time you won’t get any error. --credits Bibek Subedi

You can use the StringIO from the six module:

import six
import numpy

x = "1 3\n 4.5 8"
numpy.genfromtxt(six.StringIO(x))

The library has a section in the readme about escaping. It's Javascript-native, so I do not suggest switching to node-mysql-native. The documentation states these guidelines for escaping:

Edit: node-mysql-native is also a pure-Javascript solution.

• Numbers are left untouched
• Booleans are converted to true / false strings
• Date objects are converted to YYYY-mm-dd HH:ii:ss strings
• Buffers are converted to hex strings, e.g. X'0fa5'
• Strings are safely escaped
• Arrays are turned into list, e.g. ['a', 'b'] turns into 'a', 'b'
• Nested arrays are turned into grouped lists (for bulk inserts), e.g. [['a', 'b'], ['c', 'd']] turns into ('a', 'b'), ('c', 'd')
• Objects are turned into key = 'val' pairs. Nested objects are cast to strings.
• undefined / null are converted to NULL
• NaN / Infinity are left as-is. MySQL does not support these, and trying to insert them as values will trigger MySQL errors until they implement support.

This allows for you to do things like so:

var userId = 5;
var query = connection.query('SELECT * FROM users WHERE id = ?', [userId], function(err, results) {
  //query.sql returns SELECT * FROM users WHERE id = '5'
});

As well as this:

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  //query.sql returns INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
});

Aside from those functions, you can also use the escape functions:

connection.escape(query);
mysql.escape(query);

To escape query identifiers:

mysql.escapeId(identifier);

And as a response to your comment on prepared statements:

From a usability perspective, the module is great, but it has not yet implemented something akin to PHP's Prepared Statements.

The prepared statements are on the todo list for this connector, but this module at least allows you to specify custom formats that can be very similar to prepared statements. Here's an example from the readme:

connection.config.queryFormat = function (query, values) {
  if (!values) return query;
  return query.replace(/\:(\w+)/g, function (txt, key) {
    if (values.hasOwnProperty(key)) {
      return this.escape(values[key]);
    }
    return txt;
  }.bind(this));
};

This changes the query format of the connection so you can use queries like this:

connection.query("UPDATE posts SET title = :title", { title: "Hello MySQL" });
//equivalent to
connection.query("UPDATE posts SET title = " + mysql.escape("Hello MySQL");

Answer is already given above. Trying to differentiate between strong vs week and static vs dynamic concept.

What is Strongly typed VS Weakly typed?

Strongly Typed: Will not be automatically converted from one type to another

In Go or Python like strongly typed languages "2" + 8 will raise a type error, because they don't allow for "type coercion".

Weakly (loosely) Typed: Will be automatically converted to one type to another: Weakly typed languages like JavaScript or Perl won't throw an error and in this case JavaScript will results '28' and perl will result 10.

Perl Example:

my $a = "2" + 8;
print $a,"\n";

Save it to main.pl and run perl main.pl and you will get output 10.

What is Static VS Dynamic type?

In programming, programmer define static typing and dynamic typing with respect to the point at which the variable types are checked. Static typed languages are those in which type checking is done at compile-time, whereas dynamic typed languages are those in which type checking is done at run-time.

• Static: Types checked before run-time
• Dynamic: Types checked on the fly, during execution

What is this means?

In Go it checks typed before run-time (static check). This mean it not only translates and type-checks code it’s executing, but it will scan through all the code and type error would be thrown before the code is even run. For example,

package main

import "fmt"

func foo(a int) {
    if (a > 0) {
        fmt.Println("I am feeling lucky (maybe).")
    } else {
        fmt.Println("2" + 8)
    }
}

func main() {
    foo(2)
}

Save this file in main.go and run it, you will get compilation failed message for this.

go run main.go
# command-line-arguments
./main.go:9:25: cannot convert "2" (type untyped string) to type int
./main.go:9:25: invalid operation: "2" + 8 (mismatched types string and int)

But this case is not valid for Python. For example following block of code will execute for first foo(2) call and will fail for second foo(0) call. It's because Python is dynamically typed, it only translates and type-checks code it’s executing on. The else block never executes for foo(2), so "2" + 8 is never even looked at and for foo(0) call it will try to execute that block and failed.

def foo(a):
    if a > 0:
        print 'I am feeling lucky.'
    else:
        print "2" + 8
foo(2)
foo(0)

You will see following output

python main.py
I am feeling lucky.
Traceback (most recent call last):
  File "pyth.py", line 7, in <module>
    foo(0)
  File "pyth.py", line 5, in foo
    print "2" + 8
TypeError: cannot concatenate 'str' and 'int' objects

you can raise the click event on an element by doing

// this must be done after input1 exists in the DOM
var element = document.getElementById("input1");

if (element) element.click();

Example here

Just in case you are like me and the Id Field of the User Entity is an Int or something else other than a string,

using Microsoft.AspNet.Identity;

int userId = User.Identity.GetUserId<int>();

will do the trick

You can also do way more complex commands, just to round out the examples above. So, say I want to get the number of processes running on the system and store it in the ${NUM_PROCS} variable.

All you have to so is generate the command pipeline and stuff it's output (the process count) into the variable.

It looks something like this:

NUM_PROCS=$(ps -e | sed 1d | wc -l)

I hope that helps add some handy information to this discussion.

Here is a more complex solution. You will get full stack trace and the method toString() will be called only if needed(Performance). The attribute BuildConfig.DEBUG will be false in the production mode so all trace and debug logs will be removed. The hot spot compiler has the chance to remove the calls because off final static properties.

            StringBuilder b = new StringBuilder(args.length * 10);
            for (Object arg : args) {
                if (arg == null) {
                    b.append("null");
                } else {
                    b.append(arg);
                }
            }
            return b.toString();
        }
    }

    private String stackToString(Throwable t) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream(500);
        baos.toString();
        t.printStackTrace(new PrintStream(baos));
        return baos.toString();
    }
}

use like this:

Loggor log = new Logger();
Map foo = ...
List bar = ...
log.error("Foo:", foo, "bar:", bar);
// bad example (avoid something like this)
// log.error("Foo:" + " foo.toString() + "bar:" + bar); 

If your on MySQL 8.0 or higher you can use Window functions:

Query:

DBFiddleExample

SELECT DISTINCT
FIRST_VALUE(ID) OVER (PARTITION BY lms_attendance.USER ORDER BY lms_attendance.TIME DESC) AS ID,
FIRST_VALUE(USER) OVER (PARTITION BY lms_attendance.USER ORDER BY lms_attendance.TIME DESC) AS USER,
FIRST_VALUE(TIME) OVER (PARTITION BY lms_attendance.USER ORDER BY lms_attendance.TIME DESC) AS TIME,
FIRST_VALUE(IO) OVER (PARTITION BY lms_attendance.USER ORDER BY lms_attendance.TIME DESC) AS IO
FROM lms_attendance;

Result:

| ID | USER |       TIME |  IO |
--------------------------------
|  2 |    9 | 1370931664 | out |
|  3 |    6 | 1370932128 | out |
|  5 |   12 | 1370933037 |  in |

The advantage I see over using the solution proposed by Justin is that it enables you to select the row with the most recent data per user (or per id, or per whatever) even from subqueries without the need for an intermediate view or table.

And in case your running a HANA it is also ~7 times faster :D

The JavaScript function:

String.prototype.capitalize = function(){
       return this.replace( /(^|\s)([a-z])/g , function(m,p1,p2){ return p1+p2.toUpperCase(); } );
      };

To use this function:

capitalizedString = someString.toLowerCase().capitalize();

Also, this would work on multiple words string.

To make sure the converted City name is injected into the database, lowercased and first letter capitalized, then you would need to use JavaScript before you send it over to server side. CSS simply styles, but the actual data would remain pre-styled. Take a look at this jsfiddle example and compare the alert message vs the styled output.

if(x < 0)
if(abs(x) != x)
if(substr(strval(x), 0, 1) == "-")

try setting this

CATALINA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8

For me, I added the nuget again and the problem was solved

This is a pretty old thread but the problem is still the same -

I tried multiple things, none of them worked -

1. Added a Start In Path (without quotes)
2. Removed the complete path of the batch file in the Program/Script field etc
3. Added C:\Windows\system32\cmd.exe to the Program and added /c myscript.bat to the arguments field.

This is what worked for me -

Program/Script Field - cmd

Add Arguments - /c myscript.bat

Start In : Path to myscript.bat

Actually you should define your styles in res/values/styles.xml. I guess now you've got the following configuration:

<style name="AppBaseTheme" parent="android:Theme.Holo.Light"/>
<style name="AppTheme" parent="AppBaseTheme"/>

so if you want to use Theme.Black then change AppBaseTheme parent to android:Theme.Black or you could change app style directly in manifest file like this - android:theme="@android:style/Theme.Black". You must be lacking android namespace before style tag.

You can read more about styles and themes here.

In that case you should use ListBox control instead of dropdown and Set the SelectionMode property to Multiple

<asp:ListBox runat="server" SelectionMode="Multiple" >
  <asp:ListItem Text="test1"></asp:ListItem>
  <asp:ListItem Text="test2"></asp:ListItem>
  <asp:ListItem Text="test3"></asp:ListItem>
</asp:ListBox>

This started out as an attempt to cast video from my pc to a tv (with subtitles) eventually using Chromecast. And I ended up in this "does not play mp4" situation. However I seemed to have proved that Chrome will play (exactly the same) mp4 as long as it isn't wrapped in html(5) So here is what I have constructed. I have made a webpage under localhost and in there is a default.htm which contains:-

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<video  controls >
 <source src="sample.mp4" type="video/mp4">
 <track kind="subtitles" src="sample.vtt" label="gcsubs" srclang="eng">
</video>
</body>
</html>

the video and subtitle files are stored in the same folder as default.htm

I have the very latest version of Chrome (just updated this morning)

When I type the appropriate localhost... into my Chrome browser a black square appears with a "GO" arrow and an elapsed time bar, a mute button and an icon which says "CC". If I hit the go arrow, nothing happens (it doesn't change to "pause", the elapsed time doesn't move, and the timer sticks at 0:00. There are no error messages - nothing!

(note that if I input localhost.. to IE11 the video plays!!!!

In Chrome if I enter the disc address of sample.mp4 (i.e. C:\webstore\sample.mp4 then Chrome will play the video fine?.

This last bit is probably a working solution for Chromecast except that I cannot see any subtitles. I really want a solution with working subtitles. I just don't understand what is different in Chrome between the two methods of playing mp4

Wanting to initalize an array of fixed size is a perfectly acceptable thing to do in any programming language; it isn't like the programmer wants to put a break statement in a while(true) loop. Believe me, especially if the elements are just going to be overwritten and not merely added/subtracted, like is the case of many dynamic programming algorithms, you don't want to mess around with append statements and checking if the element hasn't been initialized yet on the fly (that's a lot of code gents).

object = [0 for x in range(1000)]

This will work for what the programmer is trying to achieve.

Multiple Approch can be applied:

• Class Based Approch: use local state and define existing field with default value:

constructor(props) {
    super(props);
    this.state = {
      value:''
    }
  }
<input type='text'
                  name='firstName'
                  value={this.state.value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />

• Using Hooks React > 16.8 in functional style components:

[value, setValue] = useState('');
<input type='text'
                  name='firstName'
                  value={value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />

• If Using propTypes and providing Default Value for propTypes in case of HOC component in functional style.

 HOC.propTypes = {
    value       : PropTypes.string
  }
  HOC.efaultProps = {
    value: ''
  }

function HOC (){

  return (<input type='text'
                  name='firstName'
                  value={this.props.value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />)

}

An important note for sending Files with Fetch API

One needs to omit content-type header for the Fetch request. Then the browser will automatically add the Content type header including the Form Boundary which looks like

Content-Type: multipart/form-data; boundary=—-WebKitFormBoundaryfgtsKTYLsT7PNUVD

Form boundary is the delimiter for the form data

TL;DR

SQLCMD -S (LOCAL) -E -V 16 -Q "IF(ISNULL(CAST(SERVERPROPERTY('ProductMajorVersion') AS INT),0)<11) RAISERROR('You need SQL 2012 or later!',16,1)"
IF ERRORLEVEL 1 GOTO :ExitFail

This uses SQLCMD (comes with SQL Server) to connect to the local server instance using Windows auth, throw an error if a version check fails and return the @@ERROR as the command line ERRORLEVEL if >= 16 (and the second line goes to the :ExitFail label if the aforementioned ERRORLEVEL is >= 1).

Watchas, Gotchas & More Info

For SQL 2000+ you can use the SERVERPROPERTY to determine a lot of this info.

While SQL 2008+ supports the ProductMajorVersion & ProductMinorVersion properties, ProductVersion has been around since 2000 (remembering that if a property is not supported the function returns NULL).

If you are interested in earlier versions you can use the PARSENAME function to split the ProductVersion (remembering the "parts" are numbered right to left i.e. PARSENAME('a.b.c', 1) returns c).

Also remember that PARSENAME('a.b.c', 4) returns NULL, because SQL 2005 and earlier only used 3 parts in the version number!

So for SQL 2008+ you can simply use:

SELECT
    SERVERPROPERTY('ProductVersion') AS ProductVersion,
    CAST(SERVERPROPERTY('ProductMajorVersion')  AS INT) AS ProductMajorVersion,
    CAST(SERVERPROPERTY ('ProductMinorVersion') AS INT) AS ProductMinorVersion;

For SQL 2000-2005 you can use:

SELECT
    SERVERPROPERTY('ProductVersion') AS ProductVersion,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) AS ProductVersion_Major,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 2 ELSE 3 END) AS INT) AS ProductVersion_Minor,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 1 ELSE 2 END) AS INT) AS ProductVersion_Revision,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 0 ELSE 1 END) AS INT) AS ProductVersion_Build;

(the PARSENAME(...,0) is a hack to improve readability)

So a check for a SQL 2000+ version would be:

IF (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) < 10) -- SQL2008
OR (
    (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) = 10) -- SQL2008
AND (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 2 ELSE 1 END) AS INT) < 5)  -- R2 (this may need to be 50)
   )
    RAISERROR('You need SQL 2008R2 or later!', 16, 1);

This is a lot simpler if you're only only interested in SQL 2008+ because SERVERPROPERTY('ProductMajorVersion') returns NULL for earlier versions, so you can use:

IF (ISNULL(CAST(SERVERPROPERTY('ProductMajorVersion') AS INT), 0) < 11) -- SQL2012
    RAISERROR('You need SQL 2012 or later!', 16, 1);

And you can use the ProductLevel and Edition (or EngineEdition) properties to determine RTM / SPn / CTPn and Dev / Std / Ent / etc respectively.

SELECT
    CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME) AS ProductVersion,
    CAST(SERVERPROPERTY('ProductLevel') AS SYSNAME)   AS ProductLevel,
    CAST(SERVERPROPERTY('Edition') AS SYSNAME)        AS Edition,
    CAST(SERVERPROPERTY('EngineEdition') AS INT)      AS EngineEdition;

FYI the major SQL version numbers are:

• 8 = SQL 2000
• 9 = SQL 2005
• 10 = SQL 2008 (and 10.5 = SQL 2008R2)
• 11 = SQL 2012
• 12 = SQL 2014
• 13 = SQL 2016
• 14 = SQL 2017

And this all works for SQL Azure too!

EDITED: You may also want to check your DB compatibility level since it could be set to a lower compatibility.

IF EXISTS (SELECT * FROM sys.databases WHERE database_id=DB_ID() AND [compatibility_level] < 110)
    RAISERROR('Database compatibility level must be SQL2008R2 or later (110)!', 16, 1)

Mostly likely middle click your mouse.

Or try Shift + Insert.

It all depends on terminal used and X11-config for mouse.

One way to connect to MySQL directly using proper MySQL username and password is:

mysql --user=root --password=mypass

Here,

root is the MySQL username
mypass is the MySQL user password

This is useful if you have a blank password.

For example, if you have MySQL user called root with an empty password, just use

mysql --user=root --password=

The file format would permit up to 255-character worksheet names, but if the Excel UI doesn't want you exceeding 31 characters, don't try to go beyond 31. App's full of weird undocumented limits and quirks, and feeding it files that are within spec but not within the range of things the testers would have tested usually causes REALLY strange behavior. (Personal favorite example: using the Excel 4.0 bytecode for an if() function, in a file with an Excel 97-style stringtable, disabled the toolbar button for bold in Excel 97.)

When you set keys (primary or foreign) you are setting constraints on how they can be used, which in turn limits what you can do with them. If you really want to alter the column, you could re-create the table without the constraints, although I'd recommend against it. Generally speaking, if you have a situation in which you want to do something, but it is blocked by a constraint, it's best resolved by changing what you want to do rather than the constraint.

you could even prototype it onto object:

Object.prototype.iterateSorted = function(worker)
{
    var keys = [];
    for (var key in this)
    {
        if (this.hasOwnProperty(key))
            keys.push(key);
    }
    keys.sort();

    for (var i = 0; i < keys.length; i++)
    {
        worker(this[ keys[i] ]);
    }
}

and the usage:

var myObj = { a:1, b:2 };
myObj.iterateSorted(function(value)
{
    alert(value);
} 

//Add "format" method to the string class
//supports:  "Welcome {0}. You are the first person named {0}".format("David");
//       and "First Name:{} Last name:{}".format("David","Wazy");
//       and "Value:{} size:{0} shape:{1} weight:{}".format(value, size, shape, weight)
String.prototype.format = function () {
    var content = this;
    for (var i = 0; i < arguments.length; i++) {
        var target = '{' + i + '}';
        content=content.split(target).join(String(arguments[i]))
        content = content.replace("{}", String(arguments[i]));
    }
    return content;
}
alert("I {} this is what {2} want and {} works for {2}!".format("hope","it","you"))

You can mix and match using positional and "named" replacement locations using this function.

I have come accross same as this problem i installed cv2 by

pip install cv2

However when i import cv2 module it displayed no module named cv2 error.
Then i searched and find cv2.pyd files in my computer and i copy and paste to site-packages directory

C:\Python27\Lib\site-packages

then i closed and reopened existing application, it worked.

EDIT I will tell how to install cv2 correctly.

1. Firstly install numpy on your computer by

pip install numpy

2. Download opencv from internet (almost 266 mb).
I download opencv-2.4.12.exe for python 2.7. Then install this opencv-2.4.12.exe file.
I extracted to C:\Users\harun\Downloads to this folder.
After installation go look for cv2.py into the folders.
For me

C:\Users\harun\Downloads\opencv\build\python\2.7\x64

in this folder take thecv2.pyd and copy it in to the

C:\Python27\Lib\site-packages

now you can able to use cv2 in you python scripts.

You can map JSON to specific class in Groovy using as operator:

import groovy.json.JsonSlurper

String json = '''
{
  "name": "John",  
  "age": 20
}
'''

def person = new JsonSlurper().parseText(json) as Person 

with(person) {
    assert name == 'John'
    assert age == 20
}

This was mentioned in another answer to this same question here, but this alone fixes this for me. I do all my builds in a separate terminal, outside of IntelliJ. So the cache's need to have the proper permissions set for the IntelliJ app to read them.

Run it from the project's root folder.

$ mvn -U idea:idea

you can use spread operator in a more basic form

[].concat(...array)

in the case of functions that return arrays but are expected to pass as arguments

Example:

function expectArguments(...args){
  return [].concat(...args);
}

JSON.stringify(expectArguments(1,2,3)) === JSON.stringify(expectArguments([1,2,3]))

C++ supplies a string class that can be used like this:

#include <string>
#include <iostream>

int main() {
    std::string Something = "Some text";
    std::cout << Something << std::endl;
}
