First, let me explain what a mem-initializer-list is. A mem-initializer-list is a comma-separated list of mem-initializers, where each mem-initializer is a member name followed by (, followed by an expression-list, followed by a ). The expression-list is how the member is constructed. For example, in

static const char s_str[] = "bodacydo";
class Example
{
private:
    int *ptr;
    string name;
    string *pname;
    string &rname;
    const string &crname;
    int age;

public:
    Example()
        : name(s_str, s_str + 8), rname(name), crname(name), age(-4)
    {
    }
};

the mem-initializer-list of the user-supplied, no-arguments constructor is name(s_str, s_str + 8), rname(name), crname(name), age(-4). This mem-initializer-list means that the name member is initialized by the std::string constructor that takes two input iterators, the rname member is initialized with a reference to name, the crname member is initialized with a const-reference to name, and the age member is initialized with the value -4.

Each constructor has its own mem-initializer-list, and members can only be initialized in a prescribed order (basically the order in which the members are declared in the class). Thus, the members of Example can only be initialized in the order: ptr, name, pname, rname, crname, and age.

When you do not specify a mem-initializer of a member, the C++ standard says:

If the entity is a nonstatic data member ... of class type ..., the entity is default-initialized (8.5). ... Otherwise, the entity is not initialized.

Here, because name is a nonstatic data member of class type, it is default-initialized if no initializer for name was specified in the mem-initializer-list. All other members of Example do not have class type, so they are not initialized.

When the standard says that they are not initialized, this means that they can have any value. Thus, because the above code did not initialize pname, it could be anything.

Note that you still have to follow other rules, such as the rule that references must always be initialized. It is a compiler error to not initialize references.

If you need the subdirectories too you need a "dir" command and a "For" command

dir /b /s DIRECTORY\*.* > list1.txt

for /f "tokens=*" %%A in (list1.txt) do echo %%~nxA >> list.txt

del list1.txt

put your root directory in dir command. It will create a list1.txt with full path names and then a list.txt with only the file names.

if The wampserver Version 2.5 then change apache configuration as

httpd.conf (apache configuration file): From

#LoadModule rewrite_module modules/mod_rewrite.so** 

To ,delete the #

LoadModule rewrite_module modules/mod_rewrite.so** 

this working fine to me

The reason you're getting the unhashable type: 'list' exception is because k = list[0:j] sets k to be a "slice" of the list, which is logically another, often shorter, list. What you need is to get just the first item in list, written like so k = list[0]. The same for v = list[j + 1:] which should just be v = list[2] for the third element of the list returned from the call to readline.split(" ").

I noticed several other likely problems with the code, of which I'll mention a few. A big one is you don't want to (re)initialize d with d = {} for each line read in the loop. Another is it's generally not a good idea to name variables the same as any of the built-ins types because it'll prevent you from being able to access one of them if you need it — and it's confusing to others who are used to the names designating one of these standard items. For that reason, you ought to rename your variable list variable something different to avoid issues like that.

Here's a working version of your with these changes in it, I also replaced the if statement expression you used to check to see if the key was already in the dictionary and now make use of a dictionary's setdefault() method to accomplish the same thing a little more succinctly.

d = {}
with open("nameerror.txt", "r") as file:
    line = file.readline().rstrip()
    while line:
        lst = line.split() # Split into sequence like ['AAA', 'x', '111'].
        k, _, v = lst[:3]  # Get first and third items.
        d.setdefault(k, []).append(v)
        line = file.readline().rstrip()

print('d: {}'.format(d))

Output:

d: {'AAA': ['111', '112'], 'AAC': ['123'], 'AAB': ['111']}

There isn’t an easy way to control the formatting Excel applies when opening a .csv file. However listed below are three approaches that might help.

My preference is the first option.

Option 1 – Change the data in the file

You could change the data in the .csv file as follows ...,=”005”,... This will be displayed in Excel as ...,005,...

Excel will have kept the data as a formula, but copying the column and using paste special values will get rid of the formula but retain the formatting

Option 2 – Format the data

If it is simply a format issue and all your data in that column has a three digits length. Then open the data in Excel and then format the column containing the data with this custom format 000

Option 3 – Change the file extension to .dif (Data interchange format)

Change the file extension and use the file import wizard to control the formats. Files with a .dif extension are automatically opened by Excel when double clicked on.

Step by step:

• Change the file extension from .csv to .dif
• Double click on the file to open it in Excel.
• The 'File Import Wizard' will be launched.
• Set the 'File type' to 'Delimited' and click on the 'Next' button.
• Under Delimiters, tick 'Comma' and click on the 'Next' button.
• Click on each column of your data that is displayed and select a 'Column data format'. The column with the value '005' should be formatted as 'Text'.
• Click on the finish button, the file will be opened by Excel with the formats that you have specified.

Based on the excellent @DMulligan's solution, here is a generic vectorized (no loops) function which splits a column of a dataframe into multiple rows, and merges it back to the original dataframe. It also uses a great generic change_column_order function from this answer.

def change_column_order(df, col_name, index):
    cols = df.columns.tolist()
    cols.remove(col_name)
    cols.insert(index, col_name)
    return df[cols]

def split_df(dataframe, col_name, sep):
    orig_col_index = dataframe.columns.tolist().index(col_name)
    orig_index_name = dataframe.index.name
    orig_columns = dataframe.columns
    dataframe = dataframe.reset_index()  # we need a natural 0-based index for proper merge
    index_col_name = (set(dataframe.columns) - set(orig_columns)).pop()
    df_split = pd.DataFrame(
        pd.DataFrame(dataframe[col_name].str.split(sep).tolist())
        .stack().reset_index(level=1, drop=1), columns=[col_name])
    df = dataframe.drop(col_name, axis=1)
    df = pd.merge(df, df_split, left_index=True, right_index=True, how='inner')
    df = df.set_index(index_col_name)
    df.index.name = orig_index_name
    # merge adds the column to the last place, so we need to move it back
    return change_column_order(df, col_name, orig_col_index)

Example:

df = pd.DataFrame([['a:b', 1, 4], ['c:d', 2, 5], ['e:f:g:h', 3, 6]], 
                  columns=['Name', 'A', 'B'], index=[10, 12, 13])
df
        Name    A   B
    10   a:b     1   4
    12   c:d     2   5
    13   e:f:g:h 3   6

split_df(df, 'Name', ':')
    Name    A   B
10   a       1   4
10   b       1   4
12   c       2   5
12   d       2   5
13   e       3   6
13   f       3   6    
13   g       3   6    
13   h       3   6    

Note that it preserves the original index and order of the columns. It also works with dataframes which have non-sequential index.

Using Java 8's Stream.filter() method in combination with List.contains():

import static java.util.Arrays.asList;
import static java.util.stream.Collectors.toList;

/* ... */

List<Integer> list1 = asList(1, 2, 3, 4, 5);
List<Integer> list2 = asList(1, 3, 5, 7, 9);

List<Integer> common = list1.stream().filter(list2::contains).collect(toList());

If you are using SQL Server 2008, I would create a stored procedure which takes a table-valued parameter. The query should then be of a particularly simple form:

CREATE PROCEDURE usp_CheckAll 
    (@param dbo.ProductTableType READONLY)
AS
BEGIN
    SELECT CAST(1 AS bit) AS Result
    WHERE (SELECT COUNT(DISTINCT ProductID) FROM @param)
        = (SELECT COUNT(DISTINCT p.ProductID) FROM @param AS p
           INNER JOIN Products 
               ON p.ProductID = Products.ProductID)
END

I changed this to return a row, as you seem to require. There are other ways to do this with a WHERE NOT EXISTS (LEFT JOIN in here WHERE rhs IS NULL):

CREATE PROCEDURE usp_CheckAll 
    (@param dbo.ProductTableType READONLY)
AS
BEGIN
    SELECT CAST(1 AS bit) AS Result
    WHERE NOT EXISTS (
        SELECT * FROM @param AS p
        LEFT JOIN Products 
            ON p.ProductID = Products.ProductID
        WHERE Products.ProductID IS NULL
    )
END

You should use the title attribute for anchor tags if you wish to apply descriptive information similarly as you would for an alt attribute. The title attribute is valid on anchor tags and is serves no other purpose than providing information about the linked page.

W3C recommends that the value of the title attribute should match the value of the title of the linked document but it's not mandatory.

http://www.w3.org/MarkUp/1995-archive/Elements/A.html

Alternatively, and likely to be more beneficial, you can use the ARIA accessibility attribute aria-label (not to be confused with aria-labeledby). aria-label serves the same function as the alt attribute does for images but for non-image elements and includes some measure of optimization since your optimizing for screen readers.

http://www.w3.org/WAI/GL/wiki/Using_aria-label_to_provide_labels_for_objects

If you want to describe an anchor tag though, it's usually appropriate to use the rel or rev tag but your limited to specific values, they should not be used for human readable descriptions.

Rel serves to describe the relationship of the linked page to the current page. (e.g. if the linked page is next in a logical series it would be rel=next)

The rev attribute is essentially the reverse relationship of the rel attribute. Rev describes the relationship of the current page to the linked page.

You can find a list of valid values here: http://microformats.org/wiki/existing-rel-values

The answers above are still using the old Python 3.4 style coroutines. Here is what you would write if you got Python 3.5+.

aiohttp supports http proxy now

import aiohttp
import asyncio

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    urls = [
            'http://python.org',
            'https://google.com',
            'http://yifei.me'
        ]
    tasks = []
    async with aiohttp.ClientSession() as session:
        for url in urls:
            tasks.append(fetch(session, url))
        htmls = await asyncio.gather(*tasks)
        for html in htmls:
            print(html[:100])

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

In your quesion code you are using TimeSpan.FromMinutes incorrectly. Please see the MSDN Documentation for TimeSpan.FromMinutes, which gives the following method signature:

public static TimeSpan FromMinutes(double value)

hence, the following code won't compile

var intMinutes = TimeSpan.FromMinutes(varTime); // won't compile

Instead, you can use the TimeSpan.TotalMinutes property to perform this arithmetic. For instance:

TimeSpan varTime = (DateTime)varFinish - (DateTime)varValue; 
double fractionalMinutes = varTime.TotalMinutes;
int wholeMinutes = (int)fractionalMinutes;

I have found that %matplotlib notebook works better for me than inline with Jupyter notebooks.

Note that you may need to restart the kernel if you were using %matplotlib inline before.

Update 2019: If you are running Jupyter Lab you might want to use %matplotlib widget

add ExcelUtility class to your project and enjoy it.

I have the same problem and I solved it by adding package to explore to the Jaxb2marshaller. For spring will be define a bean like this:

@Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        String[] packagesToScan= {"<packcge which contain the department class>"};
        marshaller.setPackagesToScan(packagesToScan);
        return marshaller;
    }

By this way if all your request and response classes are in the same package you do not need to specifically indicate the classes on the JAXBcontext

I have a similar table styled like so:

<table style="width:100%; table-layout:fixed">
    <tr>
        <td style="width: 150px">Hello, World!</td>
        <td>
            <div>
                <pre style="margin:0; overflow:scroll">My preformatted content</pre>
            </div>
        </td>
    </tr>
</table>

Try this:

sudo apt-get install -y curl

If error comes for ".settings/language.settings.xml" or any such file you don't need to git.

1. Team -> Commit -> Staged filelist, check if unwanted file exists, -> Right click on each-> remove from index.
2. From UnStaged filelist, check if unwanted file exists, -> Right click on each-> Ignore.

Now if Staged file list empty, and Unstaged file list all files are marked as Ignored. You can pull. Otherwise, follow other answers.

When the user wishes to exit all open activities, they should press a button which loads the first Activity that runs when your app starts, in my case "LoginActivity".

Intent intent = new Intent(getApplicationContext(), LoginActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);

The above code clears all the activities except for LoginActivity. LoginActivity is the first activity that is brought up when the user runs the program. Then put this code inside the LoginActivity's onCreate, to signal when it should self destruct when the 'Exit' message is passed.

    if (getIntent().getBooleanExtra("EXIT", false)) {
         finish();
    }

The answer you get to this question from the Android platform is: "Don't make an exit button. Finish activities the user no longer wants, and the Activity manager will clean them up as it sees fit."

If you don't want to install the cors library and instead want to fix your original code, the other step you are missing is that Access-Control-Allow-Origin:* is wrong. When passing Authentication tokens (e.g. JWT) then you must explicitly state every url that is calling your server. You can't use "*" when doing authentication tokens.

You should get the array like in $_POST['id']. So you should be able to do this:

foreach ($_POST['id'] as $key => $value) {
    echo $value . "<br />";
}

Input names should be same:

<input name='id[]' type='checkbox' value='1'>
<input name='id[]' type='checkbox' value='2'>
...

find . -type d > list.txt

Will list all directories and subdirectories under the current path. If you want to list all of the directories under a path other than the current one, change the . to that other path.

If you want to exclude certain directories, you can filter them out with a negative condition:

find . -type d ! -name "~snapshot" > list.txt

F.A.Q:

• Why Access-Control-Allow-Headers, Access-Control-Expose-Headers, Access-Control-Allow-Methods values are super long?

  Those do not support the * syntax, so I've collected the most common (and exotic) headers from around the web, in various formats #1 #2 #3 _{(and I will update the list from time to time)}

• Why do you use Header unset ______ syntax?

  GoDaddy servers (which my website is hosted on..) have a weird bug where if the headers are already set, the previous value will join the existing one.. (instead of replacing it) this way I "pre-clean" existing values _{(really just a a quick && dirty solution)}

• Is it safe for me to use 'as-is'?

  Well.. mostly the answer would be YES since the .htaccess is limiting the headers to the scripts (PHP, HTML, ...) and resources (.JPG, .JS, .CSS) served from the following "folder"-location. You optionally might want to remove the Access-Control-Allow-Methods lines. _{Also Connection, Time-Zone, Keep-Alive and DNT, Accept-Ranges, Vary, X-UA-Compatible, X-Frame-Options, X-Content-Type-Options and X-Xss-Protection are just a suggestion I'm using for my online-service.. feel free to remove those too...}

CSS Grid

<div>Div to be aligned vertically</div>

Your question is hard to understand, but if I'm getting the gist, you simply have some value in your main view that you want to access in a partial being rendered in that view.

If you just render a partial with just the partial name:

@Html.Partial("_SomePartial")

It will actually pass your model as an implicit parameter, the same as if you were to call:

@Html.Partial("_SomePartial", Model)

Now, in order for your partial to actually be able to use this, though, it too needs to have a defined model, for example:

@model Namespace.To.Your.Model

@Html.Action("MemberProfile", "Member", new { id = Model.Id })

Alternatively, if you're dealing with a value that's not on your view's model (it's in the ViewBag or a value generated in the view itself somehow, then you can pass a ViewDataDictionary

@Html.Partial("_SomePartial", new ViewDataDictionary { { "id", someInteger } });

And then:

@Html.Action("MemberProfile", "Member", new { id = ViewData["id"] })

As with the model, Razor will implicitly pass your partial the view's ViewData by default, so if you had ViewBag.Id in your view, then you can reference the same thing in your partial.

For large nested hashes this script could be helpful for you. It prints a nested hash in a nice python/like syntax with only indents to make it easy to copy.

module PrettyHash
  # Usage: PrettyHash.call(nested_hash)
  # Prints the nested hash in the easy to look on format
  # Returns the amount of all values in the nested hash

  def self.call(hash, level: 0, indent: 2)
    unique_values_count = 0
    hash.each do |k, v|
      (level * indent).times { print ' ' }
      print "#{k}:"
      if v.is_a?(Hash)
        puts
        unique_values_count += call(v, level: level + 1, indent: indent)
      else
        puts " #{v}"
        unique_values_count += 1
      end
    end
    unique_values_count
  end
end

Example usage:

  h = {a: { b: { c: :d }, e: :f }, g: :i }
  PrettyHash.call(h)

a:
  b:
    c: d
  e: f
g: i
=> 3

The returned value is the count (3) of all the end-level values of the nested hash.

1) Use a CSS stylesheet - add <link rel="stylesheet" type="text/css" href="styles.css" /> to include it.

2) Apply the background to the body:

body {
    background-image:url('images/background.png');
    background-repeat:no-repeat;
    background-attachment:fixed;
}

See:

http://www.w3schools.com/css/css_howto.asp

Almost what I wanted @Ralph, but here is the best answer. It'll solve your code problems:

1. it exports just the hardcoded sheet named "Sheet1";
2. it always exports to the same temp file, overwriting it;
3. it ignores the locale separation char.

To solve these problems, and meet all my requirements, I've adapted the code from here. I've cleaned it a little to make it more readable.

Option Explicit
Sub ExportAsCSV()
 
    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook
     
    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy
 
    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
      .PasteSpecial xlPasteValues
      .PasteSpecial xlPasteFormats
    End With        

    Dim Change below to "- 4"  to become compatible with .xls files
    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, Len(CurrentWB.Name) - 5) & ".csv"
     
    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

There are still some small thing with the code above that you should notice:

1. .Close and DisplayAlerts=True should be in a finally clause, but I don't know how to do it in VBA
2. It works just if the current filename has 4 letters, like .xlsm. Wouldn't work in .xls excel old files. For file extensions of 3 chars, you must change the - 5 to - 4 when setting MyFileName.
3. As a collateral effect, your clipboard will be substituted with current sheet contents.

Edit: put Local:=True to save with my locale CSV delimiter.

For me the Issue was I didn't run the setup as Administrator, after running the setup as administrator the message go away and I was prompted to install and continue process.

Try

df.loc[df.my_channel > 20000, 'my_channel'] = 0

Note: Since v0.20.0, ix has been deprecated in favour of loc / iloc.

Following madlep's answer you can also just copy one directory from another branch with the directory blob.

git checkout other-branch app/**

As to the op's question if you've only changed one file in there this will work fine ^_^

After looking at your method, I used this method to solve it.

class Register(forms.Form):
    username = forms.CharField(label='???', max_length=32)
    email = forms.EmailField(label='??', max_length=64)
    password = forms.CharField(label="??", min_length=6, max_length=16)
    captcha = forms.CharField(label="???", max_length=4)

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    for field_name in self.fields:
        field = self.fields.get(field_name)
        self.fields[field_name].widget.attrs.update({
            "placeholder": field.label,
            'class': "input-control"
        })

Some browsers support CSS tables, so you could create this kind of layout using the various CSS display: table-* values. There's more information on CSS tables in this article (and the book of the same name) by Rachel Andrew: Everything You Know About CSS is Wrong

If you need a consistent layout in older browsers that don't support CSS tables, you need to do two things:

1. Make your "table row" element clear its internal floated elements.

   The simplest way of doing this is to set overflow: hidden which takes care of most browsers, and zoom: 1 to trigger the hasLayout property in older versions of IE.

   There are many other ways of clearing floats, if this approach causes undesirable side effects you should check the question which method of 'clearfix' is best and the article on having layout for other methods.

2. Balance the height of the two "table cell" elements.

   There are two ways you could approach this. Either you can create the appearance of equal heights by setting a background image on the "table row" element (the faux columns technique) or you can make the heights of the columns match by giving each a large padding and equally large negative margin.

   Faux columns is the simpler approach and works very well when the width of one or both columns is fixed. The other technique copes better with variable width columns (based on percentage or em units) but can cause problems in some browsers if you link directly to content within your columns (e.g. if a column contained <div id="foo"></div> and you linked to #foo)

Here's an example using the padding/margin technique to balance the height of the columns.

html, body {_x000D_
  height: 100%;_x000D_
}_x000D_
_x000D_
.row {_x000D_
  zoom: 1;          /* Clear internal floats in IE */_x000D_
  overflow: hidden; /* Clear internal floats */_x000D_
}_x000D_
_x000D_
.right-column,_x000D_
.left-column {_x000D_
  padding-bottom: 1000em;  /* Balance the heights of the columns */_x000D_
  margin-bottom: -1000em;  /*                                    */_x000D_
}_x000D_
_x000D_
.right-column {_x000D_
  width: 20%;_x000D_
  float: right;_x000D_
}_x000D_
_x000D_
.left-column {_x000D_
  width: 79%;_x000D_
  float: left;_x000D_
}

<div class="row">_x000D_
  <div class="right-column">Right column content</div>_x000D_
  <div class="left-column">Left column content</div>_x000D_
</div>_x000D_
<div class="row">_x000D_
  <div class="right-column">Right column content</div>_x000D_
  <div class="left-column">Left column content</div>_x000D_
</div>

This Barcamp demo by Natalie Downe may also be useful when figuring out how to add additional columns and nice spacing and padding: Equal Height Columns and other tricks (it's also where I first learnt about the margin/padding trick to balance column heights)

Darin Dimitrov's answer shows that OrderBy is slightly faster than List.Sort when faced with already-sorted input. I modified his code so it repeatedly sorts the unsorted data, and OrderBy is in most cases slightly slower.

Furthermore, the OrderBy test uses ToArray to force enumeration of the Linq enumerator, but that obviously returns a type (Person[]) which is different from the input type (List<Person>). I therefore re-ran the test using ToList rather than ToArray and got an even bigger difference:

Sort: 25175ms
OrderBy: 30259ms
OrderByWithToList: 31458ms

Brace yourself, here there's another coming :-)

Today I had to explain to my girlfriend the difference between the expressive power of WS-Security as opposed to HTTPS. She's a computer scientist, so even if she doesn't know all the XML mumbo jumbo she understands (maybe better than me) what encryption or signature means. However I wanted a strong image, which could make her really understand what things are useful for, rather than how they are implemented (that came a bit later, she didn't escape it :-)).

So it goes like this. Suppose you are naked, and you have to drive your motorcycle to a certain destination. In the (A) case you go through a transparent tunnel: your only hope of not being arrested for obscene behaviour is that nobody is looking. That is not exactly the most secure strategy you can come out with... (notice the sweat drop from the guy forehead :-)). That is equivalent to a POST in clear, and when I say "equivalent" I mean it. In the (B) case, you are in a better situation. The tunnel is opaque, so as long as you travel into it your public record is safe. However, this is still not the best situation. You still have to leave home and reach the tunnel entrance, and once outside the tunnel probably you'll have to get off and walk somewhere... and that goes for HTTPS. True, your message is safe while it crosses the biggest chasm: but once you delivered it on the other side you don't really know how many stages it will have to go through before reaching the real point where the data will be processed. And of course all those stages could use something different than HTTP: a classical MSMQ which buffers requests which can't be served right away, for example. What happens if somebody lurks your data while they are in that preprocessing limbo? Hm. (read this "hm" as the one uttered by Morpheus at the end of the sentence "do you think it's air you are breathing?"). The complete solution (c) in this metaphor is painfully trivial: get some darn clothes on yourself, and especially the helmet while on the motorcycle!!! So you can safely go around without having to rely on opaqueness of the environments. The metaphor is hopefully clear: the clothes come with you regardless of the mean or the surrounding infrastructure, as the messsage level security does. Furthermore, you can decide to cover one part but reveal another (and you can do that on personal basis: airport security can get your jacket and shoes off, while your doctor may have a higher access level), but remember that short sleeves shirts are bad practice even if you are proud of your biceps :-) (better a polo, or a t-shirt).

I'm happy to say that she got the point! I have to say that the clothes metaphor is very powerful: I was tempted to use it for introducing the concept of policy (disco clubs won't let you in sport shoes; you can't go to withdraw money in a bank in your underwear, while this is perfectly acceptable look while balancing yourself on a surf; and so on) but I thought that for one afternoon it was enough ;-)

Will work in all browsers, including IE from version 8 and up.

issue is with the /var/lib/jenkins/.ssh/known_hosts. It exists in the first case, but not in the second one. This means you are running either on different system or the second case is somehow jailed in chroot or by other means separated from the rest of the filesystem (this is a good idea for running random code from jenkins).

Next steps are finding out how are the chroots for this user created and modify the known hosts inside this chroot. Or just go other ways of ignoring known hosts, such as ssh-keyscan, StrictHostKeyChecking=no or so.

This uses counting to create numeric unique ID. In my use, I will not be decrementing ever, even when the document that the ID is needed for is deleted.

Upon a collection creation that needs unique numeric value

1. Designate a collection appData with one document, set with .doc id only
2. Set uniqueNumericIDAmount to 0 in the firebase firestore console
3. Use doc.data().uniqueNumericIDAmount + 1 as the unique numeric id
4. Update appData collection uniqueNumericIDAmount with firebase.firestore.FieldValue.increment(1)

firebase
    .firestore()
    .collection("appData")
    .doc("only")
    .get()
    .then(doc => {
        var foo = doc.data();
        foo.id = doc.id;

        // your collection that needs a unique ID
        firebase
            .firestore()
            .collection("uniqueNumericIDs")
            .doc(user.uid)// user id in my case
            .set({// I use this in login, so this document doesn't
                  // exist yet, otherwise use update instead of set
                phone: this.state.phone,// whatever else you need
                uniqueNumericID: foo.uniqueNumericIDAmount + 1
            })
            .then(() => {

                // upon success of new ID, increment uniqueNumericIDAmount
                firebase
                    .firestore()
                    .collection("appData")
                    .doc("only")
                    .update({
                        uniqueNumericIDAmount: firebase.firestore.FieldValue.increment(
                            1
                        )
                    })
                    .catch(err => {
                        console.log(err);
                    });
            })
            .catch(err => {
                console.log(err);
            });
    });

What system are you running on? Do you have access to some sort of debugger (gdb, visual studio's debugger, etc.)?

That would give us valuable information, like the line of code where the program crashes... Also, the amount of memory may be prohibitive.

Additionally, may I recommend that you replace the numeric limits by named definitions?

As such:

#define DIM1_SZ 1000
#define DIM2_SZ 1000000

Use those whenever you wish to refer to the array dimension limits. It will help avoid typing errors.

A String in Java can be converted to "binary" with its getBytes(Charset) method.

byte[] encoded = "????????!".getBytes(StandardCharsets.UTF_8);

The argument to this method is a "character-encoding"; this is a standardized mapping between a character and a sequence of bytes. Often, each character is encoded to a single byte, but there aren't enough unique byte values to represent every character in every language. Other encodings use multiple bytes, so they can handle a wider range of characters.

Usually, the encoding to use will be specified by some standard or protocol that you are implementing. If you are creating your own interface, and have the freedom to choose, "UTF-8" is an easy, safe, and widely supported encoding.

• It's easy, because rather than including some way to note the encoding of each message, you can default to UTF-8.
• It's safe, because UTF-8 can encode any character that can be used in a Java character string.
• It's widely supported, because it is one of a small handful of character encodings that is required to be present in any Java implementation, all the way down to J2ME. Most other platforms support it too, and it's used as a default in standards like XML.

Yes. I recommend you check out Kimberly Tripp's articles on indexing.

If an index is "covering", then there is no need to use anything but the index. In SQL Server 2005, you can also add additional columns to the index that are not part of the key which can eliminate trips to the rest of the row.

Having multiple indexes, each on a single column may mean that only one index gets used at all - you will have to refer to the execution plan to see what effects different indexing schemes offer.

You can also use the tuning wizard to help determine what indexes would make a given query or workload perform the best.

Let me post a solution here for C++03 that I consider the cleanest possible.*

#define DECLARE_LAMBDA(NAME, RETURN_TYPE, FUNCTION) \
    struct { RETURN_TYPE operator () FUNCTION } NAME;

...

int main(){
  DECLARE_LAMBDA(demoLambda, void, (){ cout<<"I'm a lambda!"<<endl; });
  demoLambda();

  DECLARE_LAMBDA(plus, int, (int i, int j){
    return i+j;
  });
  cout << "plus(1,2)=" << plus(1,2) << endl;
  return 0;
}

(*) in the C++ world using macros is never considered clean.

It might mean the application is already installed for another user on your device. Users share applications. I don't know why they do but they do. So if one user updates an application is updated for the other user also. If you uninstall on one, it doesn't remove the app from the system on the other.

Here is a way to create your Custom Pagination Component from react-bootstrap lib and this component you can use Throughout your project

Your Pagination Component (pagination.jsx or js)

import React, { Component } from "react"; 
import { Pagination } from "react-bootstrap"; 
import PropTypes from "prop-types";

export default class PaginationHandler extends Component {  

   constructor(props) {
    super(props);
    this.state = {
      paging: {
        offset: 0,
        limit: 10
      },
      active: 0
    };  
    }

  pagingHandler = () => {
    let offset = parseInt(event.target.id);
    this.setState({
      active: offset
    });
    this.props.pageHandler(event.target.id - 1);   };

  nextHandler = () => {
    let active = this.state.active;
    this.setState({
      active: active + 1
    });
    this.props.pageHandler(active + 1);   };

  backHandler = () => {
    let active = this.state.active;
    this.setState({
      active: active - 1
    });
    this.props.pageHandler(active - 1);   };

  renderPageNumbers = (pageNumbers, totalPages) => {
    let { active } = this.state;
    return (
      <Pagination>
        <Pagination.Prev disabled={active < 5} onClick={ active >5 && this.backHandler} />

        {
      pageNumbers.map(number => {
              if (
                number >= parseInt(active) - 3 &&
                number <= parseInt(active) + 3 
              ) {
                return (
                  <Pagination.Item
                    id={number}
                    active={number == active}
                    onClick={this.pagingHandler}
                  >
                    {number}
                  </Pagination.Item>
                );
              } else {
                return null;
              }
        })}
        <Pagination.Next onClick={ active <= totalPages -4 && this.nextHandler} />
      </Pagination>
    );   };

  buildComponent = (props, state) => {
    const { totalPages } = props;
    const pageNumbers = [];
    for (let i = 1; i <= totalPages; i++) {
      pageNumbers.push(i);
    }
    return (
      <div className="pull-right">
      {this.renderPageNumbers(pageNumbers ,totalPages)}
      </div>
    );   
};

  render() {
    return this.buildComponent(this.props, this.state);
  } 

} 
   PaginationHandler.propTypes = 
   {
    paging: PropTypes.object,
    pageHandler: PropTypes.func,
    totalPages: PropTypes.object 
   };

Use of Above Component in your Component

import Pagination from "../pagination";

pageHandler = (offset) =>{
      this.setState(({ paging }) => ({
        paging: { ...paging, offset: offset }
      }));
   }
   render() {
    return (
      <div>
         <Pagination
          paging = {paging}
          pageHandler = {this.pageHandler}
          totalPages = {totalPages}>
          </Pagination>
      </div>
    );
  }

String input = "hello I'm a java dev" +
"no job experience needed" +
"senior software engineer" +
"java job available for senior software engineer";

String fixedInput = input.replaceAll("(java|job|senior)", "<b>$1</b>");

Although the accepted answer is correct, I'd prefer creating a new user and then using that user to access the database.

create user nodeuser@localhost identified by 'nodeuser@1234';
grant all privileges on node.* to nodeuser@localhost;
ALTER USER 'nodeuser'@localhost IDENTIFIED WITH mysql_native_password BY 'nodeuser@1234';

I know this question is old but I adapted THIS response of javascript code to C#. Hope it helps

public static void Move<T>(this List<T> list, int oldIndex, int newIndex)
{
    // exit if positions are equal or outside array
    if ((oldIndex == newIndex) || (0 > oldIndex) || (oldIndex >= list.Count) || (0 > newIndex) ||
        (newIndex >= list.Count)) return;
    // local variables
    var i = 0;
    T tmp = list[oldIndex];
    // move element down and shift other elements up
    if (oldIndex < newIndex)
    {
        for (i = oldIndex; i < newIndex; i++)
        {
            list[i] = list[i + 1];
        }
    }
        // move element up and shift other elements down
    else
    {
        for (i = oldIndex; i > newIndex; i--)
        {
            list[i] = list[i - 1];
        }
    }
    // put element from position 1 to destination
    list[newIndex] = tmp;
}

Separation of presentation and data drives my commit messages here.

Your commit message should not be hard-wrapped at any character count and instead line breaks should be used to separate thoughts, paragraphs, etc. as part of the data, not the presentation. In this case, the "data" is the message you are trying to get across and the "presentation" is how the user sees that.

I use a single summary line at the top and I try to keep it short but I don't limit myself to an arbitrary number. It would be far better if Git actually provided a way to store summary messages as a separate entity from the message but since it doesn't I have to hack one in and I use the first line break as the delimiter (luckily, many tools support this means of breaking apart the data).

For the message itself newlines indicate something meaningful in the data. A single newline indicates a start/break in a list and a double newline indicates a new thought/idea.

This is a summary line, try to keep it short and end with a line break.
This is a thought, perhaps an explanation of what I have done in human readable format.  It may be complex and long consisting of several sentences that describe my work in essay format.  It is not up to me to decide now (at author time) how the user is going to consume this data.

Two line breaks separate these two thoughts.  The user may be reading this on a phone or a wide screen monitor.  Have you ever tried to read 72 character wrapped text on a device that only displays 60 characters across?  It is a truly painful experience.  Also, the opening sentence of this paragraph (assuming essay style format) should be an intro into the paragraph so if a tool chooses it may want to not auto-wrap and let you just see the start of each paragraph.  Again, it is up to the presentation tool not me (a random author at some point in history) to try to force my particular formatting down everyone else's throat.

Just as an example, here is a list of points:
* Point 1.
* Point 2.
* Point 3.

Here's what it looks like in a viewer that soft wraps the text.

My suspicion is that the author of Git commit message recommendation you linked has never written software that will be consumed by a wide array of end-users on different devices before (i.e., a website) since at this point in the evolution of software/computing it is well known that storing your data with hard-coded presentation information is a bad idea as far as user experience goes.

In addition to keeping the variables local, one very handy use is when writing a library using a global variable, you can give it a shorter variable name to use within the library. It's often used in writing jQuery plugins, since jQuery allows you to disable the $ variable pointing to jQuery, using jQuery.noConflict(). In case it is disabled, your code can still use $ and not break if you just do:

(function($) { ...code...})(jQuery);

You can do something like this:

String [] wordList;
int wordCount = 0;
int occurrence = 1;
int arraySize = 100;
int arrayGrowth = 50;
wordList = new String[arraySize];
while ((strLine = br.readLine()) != null)   {
     // Store the content into an array
     Scanner s = new Scanner(strLine);
     while(s.hasNext()) {
         if (wordList.length == wordCount) {
              // expand list
              wordList = Arrays.copyOf(wordList, wordList.length + arrayGrowth);
         }
         wordList[wordCount] = s.next();
         wordCount++;
     } 
}

Using java.util.Arrays.copyOf(String[]) is basically doing the same thing as:

if (wordList.length == wordCount) {
    String[] temp = new String[wordList.length + arrayGrowth];
    System.arraycopy(wordList, 0, temp, 0, wordList.length);
    wordList = temp;
}

except it is one line of code instead of three. :)

You could try updating the table to get rid of these characters:

UPDATE dbo.[audit]
  SET UserID = REPLACE(UserID, CHAR(0), '')
  WHERE CHARINDEX(CHAR(0), UserID) > 0;

But then you'll also need to fix whatever is putting this bad data into the table in the first place. In the meantime perhaps try:

SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), ''))
  FROM dbo.[audit];

But that is not a long term solution. Fix the data (and the data type while you're at it). If you can't fix the data type immediately, then you can quickly find the culprit by adding a check constraint:

ALTER TABLE dbo.[audit]
  ADD CONSTRAINT do_not_allow_stupid_data
  CHECK (CHARINDEX(CHAR(0), UserID) = 0);

EDIT

Ok, so that is definitely a 4-digit integer followed by six instances of CHAR(0). And the workaround I posted definitely works for me:

DECLARE @foo TABLE(UserID VARCHAR(32));
INSERT @foo SELECT 0x31353831000000000000;

-- this succeeds:
SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), '')) FROM @foo;

-- this fails:
SELECT CONVERT(INT, UserID) FROM @foo;

Please confirm that this code on its own (well, the first SELECT, anyway) works for you. If it does then the error you are getting is from a different non-numeric character in a different row (and if it doesn't then perhaps you have a build where a particular bug hasn't been fixed). To try and narrow it down you can take random values from the following query and then loop through the characters:

SELECT UserID, CONVERT(VARBINARY(32), UserID)
  FROM dbo.[audit]
  WHERE UserID LIKE '%[^0-9]%';

So take a random row, and then paste the output into a query like this:

DECLARE @x VARCHAR(32), @i INT;
SET @x = CONVERT(VARCHAR(32), 0x...); -- paste the value here
SET @i = 1;
WHILE @i <= LEN(@x)
BEGIN
  PRINT RTRIM(@i) + ' = ' + RTRIM(ASCII(SUBSTRING(@x, @i, 1)))
  SET @i = @i + 1;
END

This may take some trial and error before you encounter a row that fails for some other reason than CHAR(0) - since you can't really filter out the rows that contain CHAR(0) because they could contain CHAR(0) and CHAR(something else). For all we know you have values in the table like:

SELECT '15' + CHAR(9) + '23' + CHAR(0);

...which also can't be converted to an integer, whether you've replaced CHAR(0) or not.

I know you don't want to hear it, but I am really glad this is painful for people, because now they have more war stories to push back when people make very poor decisions about data types.

SELECT *
FROM permlog
WHERE id = ( SELECT MAX(id) FROM permlog ) ;

This would return all rows with highest id, in case id column is not constrained to be unique.

You could try something like XLLoop. This lets you implement excel functions (UDFs) on an external server (server implementations in many different languages are provided).

For example you could use a MySQL database and Apache web server and then write the functions in PHP to serve up the data to your users.

BTW, I work on the project so let me know if you have any questions.

Another option is to mirror the S3 bucket on your web server and traverse locally. The trick is that the local files are empty and only used as a skeleton. Alternatively, the local files could hold useful meta data that you normally would need to get from S3 (e.g. filesize, mimetype, author, timestamp, uuid). When you provide a URL to download the file, search locally and but provide a link to the S3 address.

Local file traversing is easy and this approach for S3 management is language agnostic. Local file traversing also avoids maintaining and querying a database of files or delays making a series of remote API calls to authenticate and get the bucket contents.

You could allow users to upload files directly to your server via FTP or HTTP and then transfer a batch of new and updated files to Amazon at off peak times by just recursing over the directories for files with any size. On the completion of a file transfer to Amazon, replace the web server file with an empty one of the same name. If a local file has any filesize then serve it directly because its awaiting batch transfer.

The onclick handler should return false after the function call. For eg.

onclick="ConfirmDelete(); return false;">

Building on jävi's answer, this can be done without IDs or additional button attributes like this:

http://jsfiddle.net/isherwood/E5Ly5/

<button class="popper" data-toggle="popover">Pop me</button>
<div class="popper-content hide">My first popover content goes here.</div>

<button class="popper" data-toggle="popover">Pop me</button>
<div class="popper-content hide">My second popover content goes here.</div>

<button class="popper" data-toggle="popover">Pop me</button>
<div class="popper-content hide">My third popover content goes here.</div>

$('.popper').popover({
    container: 'body',
    html: true,
    content: function () {
        return $(this).next('.popper-content').html();
    }
});

Well, what do you try to do? If you want to use division, use "/" not "\". If it is something else, explain it in a bit more detail, please.

Here's a variant that lets you use a regex pattern for initial filtering, change the regex to be get the filtering you desire.

files=($(find -E . -type f -regex "^.*$"))
for item in ${files[*]}
do
  printf "   %s\n" $item
done

Note that if you use SELECT FOR UPDATE to perform a uniqueness check before an insert, you will get a deadlock for every race condition unless you enable the innodb_locks_unsafe_for_binlog option. A deadlock-free method to check uniqueness is to blindly insert a row into a table with a unique index using INSERT IGNORE, then to check the affected row count.

add below line to my.cnf file

innodb_locks_unsafe_for_binlog = 1

1 - ON
0 - OFF

There is a simple one-line answer:

Write - exit() in the command

That's it!

I found this easier to understand:

List<string> names = new List<string> { "One", "Two", "Three", "Four", "Five" };
        for (int i = 0; i < names.Count; i++)
        {
            Console.WriteLine(names[i]);
        }

You can create the ordered dict from old dict in one line:

from collections import OrderedDict
ordered_dict = OrderedDict(sorted(ship.items())

The default sorting key is by dictionary key, so the new ordered_dict is sorted by old dict's keys.

btw @aar doesn't have transitive dependency. you need a parameter to turn it on: Transitive dependencies not resolved for aar library using gradle

if(jQuery('#frmTest input[type=checkbox]:checked').length) { … }

May be it's good if you define your background-image in the :after pseudo class. Write like this:

.parent{
    width:300px;
    height:300px;
    position:relative;
    border:1px solid red;
}
.parent:after{
    content:'';
    background:url('http://www.dummyimage.com/300x300/000/fff&text=parent+image');
    width:300px;
    height:300px;
    position:absolute;
    top:0;
    left:0;
    opacity:0.5;
}
.child{
    background:yellow;
    position:relative;
    z-index:1;
}

Some of these have already been mentioned, but here's what I can think of off the top of my head:

• Follow KVO naming rules. Even if you don't use KVO now, in my experience often times it's still beneficial in the future. And if you are using KVO or bindings, you need to know things are going work the way they are supposed to. This covers not just accessor methods and instance variables, but to-many relationships, validation, auto-notifying dependent keys, and so on.
• Put private methods in a category. Not just the interface, but the implementation as well. It's good to have some distance conceptually between private and non-private methods. I include everything in my .m file.
• Put background thread methods in a category. Same as above. I've found it's good to keep a clear conceptual barrier when you're thinking about what's on the main thread and what's not.
• Use #pragma mark [section]. Usually I group by my own methods, each subclass's overrides, and any information or formal protocols. This makes it a lot easier to jump to exactly what I'm looking for. On the same topic, group similar methods (like a table view's delegate methods) together, don't just stick them anywhere.
• Prefix private methods & ivars with _. I like the way it looks, and I'm less likely to use an ivar when I mean a property by accident.
• Don't use mutator methods / properties in init & dealloc. I've never had anything bad happen because of it, but I can see the logic if you change the method to do something that depends on the state of your object.
• Put IBOutlets in properties. I actually just read this one here, but I'm going to start doing it. Regardless of any memory benefits, it seems better stylistically (at least to me).
• Avoid writing code you don't absolutely need. This really covers a lot of things, like making ivars when a #define will do, or caching an array instead of sorting it each time the data is needed. There's a lot I could say about this, but the bottom line is don't write code until you need it, or the profiler tells you to. It makes things a lot easier to maintain in the long run.
• Finish what you start. Having a lot of half-finished, buggy code is the fastest way to kill a project dead. If you need a stub method that's fine, just indicate it by putting NSLog( @"stub" ) inside, or however you want to keep track of things.

Change this dialog.cancel(); to dialog.dismiss();

The solution is to call dismiss() on the Dialog you created in NetErrorPage.java:114 before exiting the Activity, e.g. in onPause().

Views have a reference to their parent Context (taken from constructor argument). If you leave an Activity without destroying Dialogs and other dynamically created Views, they still hold this reference to your Activity (if you created with this as Context: like new ProgressDialog(this)), so it cannot be collected by the GC, causing a memory leak.

I've found this issue to be prevalent in Entity Framework when we instantiate an Entity manually rather than through DBContext which will resolve all the Navigation Properties. If there are Foreign Key references (Navigation Properties) between tables and you use those references in your lambda (e.g. ProductDetail.Products.ID) then that "Products" context remains null if you manually created the Entity.

The most likely explanations for that error are:

1. The file you are attempting to load is not an executable file. CreateProcess requires you to provide an executable file. If you wish to be able to open any file with its associated application then you need ShellExecute rather than CreateProcess.
2. There is a problem loading one of the dependencies of the executable, i.e. the DLLs that are linked to the executable. The most common reason for that is a mismatch between a 32 bit executable and a 64 bit DLL, or vice versa. To investigate, use Dependency Walker's profile mode to check exactly what is going wrong.

Reading down to the bottom of the code, I can see that the problem is number 1.

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

Happen with me because I ran git config core.autocrlf true and I forgot to rever back.

After that, when I checkout/pull new code, all LF (break line in Unix) was replaced by CRLF (Break line in Windows).

I ran linter, and all error messages are Expected linebreaks to be 'LF' but found 'CRLF'

To fix the issue, I checked autocrlf value by running git config --list | grep autocrlf and I got:

core.autocrlf=true
core.autocrlf=false

I edited the global GIT config ~/.gitconfig and replaced autocrlf = true by autocrlf = false.

After that, I went to my project and do the following (assuming the code in src/ folder):

CURRENT_BRANCH=$(git branch | grep \* | cut -d ' ' -f2);
rm -rf src/*
git checkout $CURRENT_BRANCH src/

re.sub is definitely what you are looking for. And so you know, you don't need the anchors and the wildcards.

re.sub(r"(?i)interfaceOpDataFile", "interfaceOpDataFile %s" % filein, line)

will do the same thing--matching the first substring that looks like "interfaceOpDataFile" and replacing it.

write in file config

$config['base_url'] = 'http://localhost:8000/test/content/home/';

If you have names of the element and not id we can achieve the undefined check on all text elements (for example) as below and fill them with a default value say 0.0:

var aFieldsCannotBeNull=['ast_chkacc_bwr','ast_savacc_bwr'];
 jQuery.each(aFieldsCannotBeNull,function(nShowIndex,sShowKey) {
   var $_oField = jQuery("input[name='"+sShowKey+"']");
   if($_oField.val().trim().length === 0){
       $_oField.val('0.0')
    }
  })

The proper way to do it is using the ng-options directive. The HTML would look like this.

<select ng-model="selectedTestAccount" 
        ng-options="item.Id as item.Name for item in testAccounts">
    <option value="">Select Account</option>
</select>

JavaScript:

angular.module('test', []).controller('DemoCtrl', function ($scope, $http) {
    $scope.selectedTestAccount = null;
    $scope.testAccounts = [];

    $http({
            method: 'GET',
            url: '/Admin/GetTestAccounts',
            data: { applicationId: 3 }
        }).success(function (result) {
        $scope.testAccounts = result;
    });
});

You'll also need to ensure angular is run on your html and that your module is loaded.

<html ng-app="test">
    <body ng-controller="DemoCtrl">
    ....
    </body>
</html>

It seems you don't want to keep the whole DataTable as a copy, because you only need some rows, right? If you got a creteria you can specify with a select on the table, you could copy just those rows to an extra backup array of DataRow like

DataRow[] rows = sourceTable.Select("searchColumn = value");

The .Select() function got several options and this one e.g. can be read as a SQL

SELECT * FROM sourceTable WHERE searchColumn = value;

Then you can import the rows you want as described above.

targetTable.ImportRows(rows[n])

...for any valid n you like, but the columns need to be the same in each table.

Some things you should know about ImportRow is that there will be errors during runtime when using primary keys!

First I wanted to check whether a row already existed which also failed due to a missing primary key, but then the check always failed. In the end I decided to clear the existing rows completely and import the rows I wanted again.

The second issue did help to understand what happens. The way I'm using the import function is to duplicate rows with an exchanged entry in one column. I realized that it always changed and it still was a reference to the row in the array. I first had to import the original and then change the entry I wanted.

The reference also explains the primary key errors that appeared when I first tried to import the row as it really was doubled up.

JSON can be written into local storage using the JSON.stringify to serialize a JS object. You cannot write to a JSON file using only JS. Only cookies or local storage

    var obj = {"nissan": "sentra", "color": "green"};

localStorage.setItem('myStorage', JSON.stringify(obj));

And to retrieve the object later

var obj = JSON.parse(localStorage.getItem('myStorage'));

You need the <pre></pre> tags for the line breaks, and the {@code ... } inside them for generics. But then it's not allowed to place the opening brace on the same line as the <generic> tag, because then everything will be displayed on 1 line again.

Displays on one line:

* ..
* <pre>
* {@code
* public List<Object> getObjects() {
*    return objects;
* }
* </pre>
* ..

Displays with line breaks:

* ..
* <pre>
* {@code
* public List<Object> getObjects() 
* {
*    return objects;
* }
* </pre>
* ..

Another weird thing is when you paste the closing brace of {@code, it gets displayed:

* ..
* <pre>
* {@code
*   public List<Object> getObjects() 
*   {
*     return objects;
*   }
* }
* </pre>
* ..

Output:

public List<Object> getObjects() 
{
   return objects;
}
}

I've never had problems with deploying small console application made in C# as-is. The only problem you can bump into would be a dependency on the .NET framework, but even that shouldn't be a major problem. You could try using version 2.0 of the framework, which should already be on most PCs.

Using native, unmanaged C++, you should not have any dependencies on the .NET framework, so you really should be safe. Just grab the executable and any accompanying files (if there are any) and deploy them as they are; there's no need to install them if you don't want to.

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

here is a copy-paste example that worked for me.

I got this error because of the file was opened in another instance.

when i closed the file and again re-build the solution, it was successfully copied.

"var" is one of those things that people either love or hate (like regions). Though, unlike regions, var is absolutely necessary when creating anonymous classes.

To me, var makes sense when you are newing up an object directly like:

var dict = new Dictionary<string, string>();

That being said, you can easily just do:

Dictionary<string, string> dict = new and intellisense will fill in the rest for you here.

If you only want to work with a specific interface, then you can't use var unless the method you are calling returns the interface directly.

Resharper seems to be on the side of using "var" all over, which may push more people to do it that way. But I kind of agree that it is harder to read if you are calling a method and it isn't obvious what is being returned by the name.

var itself doesn't slow things down any, but there is one caveat to this that not to many people think about. If you do var result = SomeMethod(); then the code after that is expecting some sort of result back where you'd call various methods or properties or whatever. If SomeMethod() changed its definition to some other type but it still met the contract the other code was expecting, you just created a really nasty bug (if no unit/integration tests, of course).

There is an easy way to check socket connection state via poll call. First, you need to poll socket, whether it has POLLIN event.

1. If socket is not closed and there is data to read then read will return more than zero.
2. If there is no new data on socket, then POLLIN will be set to 0 in revents
3. If socket is closed then POLLIN flag will be set to one and read will return 0.

Here is small code snippet:

int client_socket_1, client_socket_2;
if ((client_socket_1 = accept(listen_socket, NULL, NULL)) < 0)
{
    perror("Unable to accept s1");
    abort();
}
if ((client_socket_2 = accept(listen_socket, NULL, NULL)) < 0)
{
    perror("Unable to accept s2");
    abort();
}
pollfd pfd[]={{client_socket_1,POLLIN,0},{client_socket_2,POLLIN,0}};
char sock_buf[1024]; 
while (true)
{
    poll(pfd,2,5);
    if (pfd[0].revents & POLLIN)
    {
        int sock_readden = read(client_socket_1, sock_buf, sizeof(sock_buf));
        if (sock_readden == 0)
            break;
        if (sock_readden > 0)
            write(client_socket_2, sock_buf, sock_readden);
    }
    if (pfd[1].revents & POLLIN)
    {
        int sock_readden = read(client_socket_2, sock_buf, sizeof(sock_buf));
        if (sock_readden == 0)
            break;
        if (sock_readden > 0)
            write(client_socket_1, sock_buf, sock_readden);
    }
}

If you have setter and getter as private it will come up in PMD checks.

CAUTION: Do not use jQuery to test your jQuery

When you are using any of the code provided by other users and if you want to display the message on your window and not on the alert or console.log, Then make sure you use javascript and not jquery.

Not everyone want to use alert or console.log

alert('jquery is working');
console.log('jquery is working');

The code below will fail to display the message
Because we are using jquery inside the else (how the hell the message displays on your screen if you do not have jquery)

if ('undefined' == typeof window.jQuery) {
    $('#selector').appendTo('jquery is NOT working');
} else {
    $('#selector').appendTo('jquery is working');
}

Use JavaScript instead

if ('undefined' == typeof window.jQuery) {
    document.getElementById('selector').innerHTML = "jquery is NOT working";
} else {
    document.getElementById('selector').innerHTML = "jquery is working";
}

Without seeing your code, it's hard to answer other than a stab in the dark. I would guess that the string you're passing to encodeURIComponent(), which is the correct method to use, is coming from the result of accessing the innerHTML property. The solution is to get the innerText/textContent property value instead:

var str, 
    el = document.getElementById("myUrl");

if ("textContent" in el)
    str = encodeURIComponent(el.textContent);
else
    str = encodeURIComponent(el.innerText);

If that isn't the case, you can use the replace() method to replace the HTML entity:

encodeURIComponent(str.replace(/&/g, "&"));

This worked. The first row had column names in it.

COPY wheat FROM 'wheat_crop_data.csv' DELIMITER ';' CSV HEADER

You could add this little snippet of code to add a nice "…" to the ending of the line if the content is to large to fit on one line:

li {
  overflow: hidden; 
  text-overflow: ellipsis;
  white-space: nowrap;
}

The reason your attempt wasn't working, is because the two animations (fade-in and fade-out) were working against each other.

Right before an object became visible, it was still invisible and so the animation for fading-out would run. Then, the fraction of a second later when that same object had become visible, the fade-in animation would try to run, but the fade-out was still running. So they would work against each other and you would see nothing.

Eventually the object would become visible (most of the time), but it would take a while. And if you would scroll down by using the arrow-button at the button of the scrollbar, the animation would sort of work, because you would scroll using bigger increments, creating less scroll-events.

Enough explanation, the solution (JS, CSS, HTML):

$(window).on("load",function() {_x000D_
  $(window).scroll(function() {_x000D_
    var windowBottom = $(this).scrollTop() + $(this).innerHeight();_x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectBottom = $(this).offset().top + $(this).outerHeight();_x000D_
      _x000D_
      /* If the element is completely within bounds of the window, fade it in */_x000D_
      if (objectBottom < windowBottom) { //object comes into view (scrolling down)_x000D_
        if ($(this).css("opacity")==0) {$(this).fadeTo(500,1);}_x000D_
      } else { //object goes out of view (scrolling up)_x000D_
        if ($(this).css("opacity")==1) {$(this).fadeTo(500,0);}_x000D_
      }_x000D_
    });_x000D_
  }).scroll(); //invoke scroll-handler on page-load_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_
}

• I wrapped the fade-codeline in an if-clause: if ($(this).css("opacity")==0) {...}. This makes sure the object is only faded in when the opacity is 0. Same goes for fading out. And this prevents the fade-in and fade-out from working against each other, because now there's ever only one of the two running at one time on an object.
• I changed .animate() to .fadeTo(). It's jQuery's specialized function for opacity, a lot shorter to write and probably lighter than animate.
• I changed .position() to .offset(). This always calculates relative to the body, whereas position is relative to the parent. For your case I believe offset is the way to go.
• I changed $(window).height() to $(window).innerHeight(). The latter is more reliable in my experience.
• Directly after the scroll-handler, I invoke that handler once on page-load with $(window).scroll();. Now you can give all desired objects on the page the .fade class, and objects that should be invisible at page-load, will be faded out immediately.
• I removed #container from both HTML and CSS, because (at least for this answer) it isn't necessary. (I thought maybe you needed the height:2000px because you used .position() instead of .offset(), otherwise I don't know. Feel free of course to leave it in your code.)

UPDATE

If you want opacity values other than 0 and 1, use the following code:

$(window).on("load",function() {_x000D_
  function fade(pageLoad) {_x000D_
    var windowBottom = $(window).scrollTop() + $(window).innerHeight();_x000D_
    var min = 0.3;_x000D_
    var max = 0.7;_x000D_
    var threshold = 0.01;_x000D_
    _x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectBottom = $(this).offset().top + $(this).outerHeight();_x000D_
      _x000D_
      /* If the element is completely within bounds of the window, fade it in */_x000D_
      if (objectBottom < windowBottom) { //object comes into view (scrolling down)_x000D_
        if ($(this).css("opacity")<=min+threshold || pageLoad) {$(this).fadeTo(500,max);}_x000D_
      } else { //object goes out of view (scrolling up)_x000D_
        if ($(this).css("opacity")>=max-threshold || pageLoad) {$(this).fadeTo(500,min);}_x000D_
      }_x000D_
    });_x000D_
  } fade(true); //fade elements on page-load_x000D_
  $(window).scroll(function(){fade(false);}); //fade elements on scroll_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_
}

• I added a threshold to the if-clause, see explanation below.
• I created variables for the threshold and for min/max at the start of the function. In the rest of the function these variables are referenced. This way, if you ever want to change the values again, you only have to do it in one place.
• I also added || pageLoad to the if-clause. This was necessary to make sure all objects are faded to the correct opacity on page-load. pageLoad is a boolean that is send along as an argument when fade() is invoked.
  I had to put the fade-code inside the extra function fade() {...}, in order to be able to send along the pageLoad boolean when the scroll-handler is invoked.
  I did't see any other way to do this, if anyone else does, please leave a comment.

Explanation:
The reason the code in your fiddle didn't work, is because the actual opacity values are always a little off from the value you set it to. So if you set the opacity to 0.3, the actual value (in this case) is 0.300000011920929. That's just one of those little bugs you have to learn along the way by trail and error. That's why this if-clause won't work: if ($(this).css("opacity") == 0.3) {...}.

I added a threshold, to take that difference into account: == 0.3 becomes <= 0.31.
(I've set the threshold to 0.01, this can be changed of course, just as long as the actual opacity will fall between the set value and this threshold.)

The operators are now changed from == to <= and >=.

UPDATE 2:

If you want to fade the elements based on their visible percentage, use the following code:

$(window).on("load",function() {_x000D_
  function fade(pageLoad) {_x000D_
    var windowTop=$(window).scrollTop(), windowBottom=windowTop+$(window).innerHeight();_x000D_
    var min=0.3, max=0.7, threshold=0.01;_x000D_
    _x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectHeight=$(this).outerHeight(), objectTop=$(this).offset().top, objectBottom=$(this).offset().top+objectHeight;_x000D_
      _x000D_
      /* Fade element in/out based on its visible percentage */_x000D_
      if (objectTop < windowTop) {_x000D_
        if (objectBottom > windowTop) {$(this).fadeTo(0,min+((max-min)*((objectBottom-windowTop)/objectHeight)));}_x000D_
        else if ($(this).css("opacity")>=min+threshold || pageLoad) {$(this).fadeTo(0,min);}_x000D_
      } else if (objectBottom > windowBottom) {_x000D_
        if (objectTop < windowBottom) {$(this).fadeTo(0,min+((max-min)*((windowBottom-objectTop)/objectHeight)));}_x000D_
        else if ($(this).css("opacity")>=min+threshold || pageLoad) {$(this).fadeTo(0,min);}_x000D_
      } else if ($(this).css("opacity")<=max-threshold || pageLoad) {$(this).fadeTo(0,max);}_x000D_
    });_x000D_
  } fade(true); //fade elements on page-load_x000D_
  $(window).scroll(function(){fade(false);}); //fade elements on scroll_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_
}

@Alan's answer will do what you're looking for, but this solution fails when you use the responsive capabilities of Bootstrap. In your case, you're using the xs sizes so you won't notice, but if you used anything else (e.g. col-sm, col-md, etc), you'd understand.

Another approach is to play with margins and padding. See the updated fiddle: http://jsfiddle.net/jz8j247x/1/

.left-side {
  background-color: blue;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.something {
  height: 100%;
  background-color: red;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.row {
  background-color: green;
  overflow: hidden;
}

Let'e me give an example:

1. client connect to server, and send 1MB data to server every 1 second.

2. server side accept a connection, and then sleep 20 second, without recv msg from client.So the tcp send buffer in the client side will be full.

Code in client side:

#include <arpa/inet.h>
#include <sys/socket.h>
#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
#include <stdlib.h>
#include <string.h>
#define exit_if(r, ...)                                                                          \
    if (r) {                                                                                     \
        printf(__VA_ARGS__);                                                                     \
        printf("%s:%d error no: %d error msg %s\n", __FILE__, __LINE__, errno, strerror(errno)); \
        exit(1);                                                                                 \
    }

void setNonBlock(int fd) {
    int flags = fcntl(fd, F_GETFL, 0);
    exit_if(flags < 0, "fcntl failed");
    int r = fcntl(fd, F_SETFL, flags | O_NONBLOCK);
    exit_if(r < 0, "fcntl failed");
}

void test_full_sock_buf_1(){
    short port = 8000;
    struct sockaddr_in addr;
    memset(&addr, 0, sizeof addr);
    addr.sin_family = AF_INET;
    addr.sin_port = htons(port);
    addr.sin_addr.s_addr = INADDR_ANY;


    int fd = socket(AF_INET, SOCK_STREAM, 0);
    exit_if(fd<0, "create socket error");

    int ret = connect(fd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
    exit_if(ret<0, "connect to server error");
    setNonBlock(fd);

    printf("connect to server success");

    const int LEN = 1024 * 1000;
    char msg[LEN];  // 1MB data
    memset(msg, 'a', LEN);

    for (int i = 0; i < 1000; ++i) {
        int len = send(fd, msg, LEN, 0);
        printf("send: %d, erron: %d, %s \n", len, errno, strerror(errno));
        sleep(1);
    }

}

int main(){
    test_full_sock_buf_1();

    return 0;
}

Code in server side:

    #include <arpa/inet.h>
    #include <sys/socket.h>
    #include <stdio.h>
    #include <errno.h>
    #include <fcntl.h>
    #include <stdlib.h>
    #include <string.h>
    #define exit_if(r, ...)                                                                          \
        if (r) {                                                                                     \
            printf(__VA_ARGS__);                                                                     \
            printf("%s:%d error no: %d error msg %s\n", __FILE__, __LINE__, errno, strerror(errno)); \
            exit(1);                                                                                 \
        }
void test_full_sock_buf_1(){

    int listenfd = socket(AF_INET, SOCK_STREAM, 0);
    exit_if(listenfd<0, "create socket error");

    short port = 8000;
    struct sockaddr_in addr;
    memset(&addr, 0, sizeof addr);
    addr.sin_family = AF_INET;
    addr.sin_port = htons(port);
    addr.sin_addr.s_addr = INADDR_ANY;

    int r = ::bind(listenfd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
    exit_if(r<0, "bind socket error");

    r = listen(listenfd, 100);
    exit_if(r<0, "listen socket error");

    struct sockaddr_in raddr;
    socklen_t rsz = sizeof(raddr);
    int cfd = accept(listenfd, (struct sockaddr *) &raddr, &rsz);
    exit_if(cfd<0, "accept socket error");

    sockaddr_in peer;
    socklen_t alen = sizeof(peer);
    getpeername(cfd, (sockaddr *) &peer, &alen);

    printf("accept a connection from %s:%d\n", inet_ntoa(peer.sin_addr), ntohs(peer.sin_port));

    printf("but now I will sleep 15 second, then exit");
    sleep(15);
}

Start server side, then start client side.

server side may output:

accept a connection from 127.0.0.1:35764
but now I will sleep 15 second, then exit
Process finished with exit code 0

client side may output:

connect to server successsend: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success

send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 

You can see, as the server side doesn't recv the data from client, so when the client side tcp buffer get full, but you still send data, so you may get Resource temporarily unavailable error.

It is better to implement it as in the snippet below.

You could use groupby to split the DataFrame into subgroups according to the color:

for key, grp in df.groupby(['color']):

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

df = pd.read_table('data', sep='\s+')
fig, ax = plt.subplots()

for key, grp in df.groupby(['color']):
    ax = grp.plot(ax=ax, kind='line', x='x', y='y', c=key, label=key)

plt.legend(loc='best')
plt.show()

yields

I understand you asked for sendmail but why not use the default mail? It can easily send html emails.

Works on: RHEL 5.10/6.x & CentOS 5.8

Example:

cat ~/campaigns/release-status.html | mail -s "$(echo -e "Release Status [Green]\nContent-Type: text/html")" [email protected] -v

A jump statement such as a break is required after each case block, including the last block whether it is a case statement or a default statement. With one exception, (unlike the C++ switch statement), C# does not support an implicit fall through from one case label to another. The one exception is if a case statement has no code.

-- C# switch() documentation

Maybe I'm not understanding the question but here is my simple solution that works -

# I want to Display total heads bent this machine so I define a label -
TotalHeadsLabel3 = Label(leftFrame)
TotalHeadsLabel3.config(font=Helv12,fg='blue',text="Total heads " + str(TotalHeads))
TotalHeadsLabel3.pack(side=TOP)

# I update the int variable adding the quantity bent -
TotalHeads = TotalHeads + headQtyBent # update ready to write to file & display
TotalHeadsLabel3.config(text="Total Heads "+str(TotalHeads)) # update label with new qty

I agree that labels are not automatically updated but can easily be updated with the

<label name>.config(text="<new text>" + str(<variable name>))

That just needs to be included in your code after the variable is updated.

Pipe stderr to /dev/null by using 2>/dev/null

find . -name '...' 2>/dev/null

In Kotlin, my solution, combining above answers.

class CustomViewPager(context: Context, attrs: AttributeSet): ViewPager(context, attrs) {
    var swipeEnabled = false

    override fun onTouchEvent(ev: MotionEvent?): Boolean {
        return if (swipeEnabled) super.onTouchEvent(ev) else false
    }

    override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean {
        return if (swipeEnabled) super.onInterceptTouchEvent(ev) else false
    }

    override fun executeKeyEvent(event: KeyEvent): Boolean {
        return if (swipeEnabled) super.executeKeyEvent(event) else false
    }
}

You can easily verify a certificate chain with openssl. The fullchain will include the CA cert so you should see details about the CA and the certificate itself.

openssl x509 -in fullchain.pem -text -noout

Here is code for actual Phone keyboard on Android:

Key part: keyboardType: TextInputType.phone,

  TextFormField(
    style: TextStyle(
      fontSize: 24
    ),
    controller: _phoneNumberController,
    keyboardType: TextInputType.phone,
    decoration: InputDecoration(
      prefixText: "+1 ",
      labelText: 'Phone number'),
    validator: (String value) {
      if (value.isEmpty) {
        return 'Phone number (+x xxx-xxx-xxxx)';
      }
      return null;
    },
  ),

I used :

from pil import Image

instead of

from PIL import Image

and it worked for me fine

Write above code inside following tags < Directory "c:\projects" > < / Directory > c:(you can add any directory d: e:) is drive where you have created your project folder.

Alias /projects "c:\projects"

Now you can access the pr0jects directory on your browser :

localhost/projects/

Check your project's properties. On the "Application" tab, select your Program class as the Startup object:

Guava looks like a good option:

Iterables.toString(myIterable)

Works Regardless of Pip Version

Run the following in your python editor or IPython:

import pkg_resources
installed_packages = {d.project_name: d.version for d in pkg_resources.working_set}
print(installed_packages)

Read other answers and pulled together this combo, which is quickest and easiest inside Python.

Find the specific Packages

Conveniently you can then get items from your dict easily, i.e.

installed_packages['pandas'] >> '1.16.4'

From the console in Chrome, you can do console.log(data_to_be_displayed).

Using nick craver's solution with selectivizr allows for a cross browser solution (IE6+)

You need to import FormsModule in your @NgModule Decorator, @NgModule is present in your moduleName.module.ts file.

import { FormsModule } from '@angular/forms';
@NgModule({
   imports: [
      BrowserModule,
      FormsModule
   ],
   declarations: [ AppComponent ],
   bootstrap: [ AppComponent ]
 })

f = ... # file-like object, i.e. supporting read(size) function and 
        # returning empty string '' when there is nothing to read

def chunked(file, chunk_size):
    return iter(lambda: file.read(chunk_size), '')

for data in chunked(f, 65536):
    # process the data

UPDATE: The approach is best explained in https://stackoverflow.com/a/4566523/38592

Your code works fine.

def list = [["c":"d"], ["e":"f"], ["g":"h"]]
Map tmpHM = [1:"second (e:f)", 0:"first (c:d)", 2:"third (g:h)"]

for (objKey in tmpHM.keySet()) {   
    HashMap objHM = (HashMap) list.get(objKey);
    print("objHM: ${objHM}  , ")
}

prints objHM: [e:f] , objHM: [c:d] , objHM: [g:h] ,

I would like to add some additional aspect of this discussion. In windows OS I have observed that when a jar file containing schema is stored in a directory whose path contains a space character, for instance like in the following example

"c:\Program Files\myApp\spring-beans-4.0.2.RELEASE.jar"

then specifying schema location URL in the following way is not sufficient when you are developing some standalone application that should work also offline

<beans
 xsi:schemaLocation="
   http://www.springframework.org/schema/beans org/springframework/beans/factory/xml/spring-beans-2.0.xsd"
    />

I have learned that result of such schema location URL resolution is a file which has a path like the following

"c:\Program%20Files\myApp\spring-beans-4.0.2.RELEASE.jar"

When I started my application from some other directory which didn't contain space character on its path then schema location resolution worked fine. Maybe somebody faced similar problems? Nevertheless I discoverd that classpath protocol works fine in my case

<beans
 xsi:schemaLocation="
   http://www.springframework.org/schema/beans classpath:org/springframework/beans/factory/xml/spring-beans-2.0.xsd"
    />

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

I tried @Mr. Stark answer. It didn't work. It failed to install the drive. I have Samsung S8 plus. I enabled the debugging mode on device then installed Android USB Driver for Windows from Samsung site, it works.

There are several techniques using of runOnUiThread(), lets see all

This is my main thread (UI thread) called AndroidBasicThreadActivity and I'm going to update it from a worker thread in various ways -

public class AndroidBasicThreadActivity extends AppCompatActivity
{
    public static TextView textView;
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_android_basic_thread);

        textView = (TextView) findViewById(R.id.textview);

        MyAndroidThread myTask = new MyAndroidThread(AndroidBasicThreadActivity.this);
        Thread t1 = new Thread(myTask, "Bajrang");
        t1.start();
    }
}

1.) By passing Activity's instance as an argument on worker thread

class MyAndroidThread implements Runnable
{
    Activity activity;
    public MyAndroidThread(Activity activity)
    {
        this.activity = activity;
    }
    @Override
    public void run()
    {

        //perform heavy task here and finally update the UI with result this way - 
        activity.runOnUiThread(new Runnable()
        {
            @Override
            public void run()
            {
                AndroidBasicThreadActivity.textView.setText("Hello!! Android Team :-) From child thread.");
            }
        });
    }
}

2.) By using View's post(Runnable runnable) method in worker thread

class MyAndroidThread implements Runnable
{
    Activity activity;
    public MyAndroidThread(Activity activity)
    {
        this.activity = activity;
    }
    @Override
    public void run()
    {
     //perform heavy task here and finally update the UI with result this way - 
       AndroidBasicThreadActivity.textView.post(new Runnable()
      { 
        @Override
        public void run()
        {
            AndroidBasicThreadActivity.textView.setText("Hello!! Android Team :-) From child thread.");
        }
    });

    }
}

3.) By using Handler class from android.os package If we don't have the context (this/ getApplicationContext()) or Activity's instance (AndroidBasicThreadActivity.this) then we have to use Handler class as below -

class MyAndroidThread implements Runnable
{
    Activity activity;
    public MyAndroidThread(Activity activity)
    {
        this.activity = activity;
    }
    @Override
   public void run()
  {
  //perform heavy task here and finally update the UI with result this way - 
  new Handler(Looper.getMainLooper()).post(new Runnable() {
        public void run() {
            AndroidBasicThreadActivity.textView.setText("Hello!! Android Team :-) From child thread.");
        }
    });
  }
}

In terminal:

cd C:\xampp\mysql\bin

mysql -h 127.0.0.1 --port=3306 -u root --password

Hit ENTER if the password is an empty string. Now you are in. You can list all available databases, and select one using the fallowing:

SHOW DATABASES;
USE database_name_here;

SHOW TABLES
DESC table_name_here
SELECT * FROM table_name_here

Remember about the ";" at the end of each SQL statement.

Windows cmd terminal is not very nice and does not support Ctrl + C, Ctrl + V (copy, paste) shortcuts. If you plan to work a lot in terminal, consider installing an alternative terminal cmd line, I use cmder terminal - Download Page

Removal invalidates only the iterators that point to the elements that are removed.

So in this case after removing *i , i is invalidated and you cannot do increment on it.

What you can do is first save the iterator of element that is to be removed , then increment the iterator and then remove the saved one.

One liner:
for file in *.php ; do mv "$file" "_$file" ; done

SELECT @i:=@i+1 AS iterator, t.*
FROM tablename t,(SELECT @i:=0) foo

Use the script console (Manage Jenkins > Script Console) and something like this script to bulk delete a job's build history https://github.com/jenkinsci/jenkins-scripts/blob/master/scriptler/bulkDeleteBuilds.groovy

That script assumes you want to only delete a range of builds. To delete all builds for a given job, use this (tested):

// change this variable to match the name of the job whose builds you want to delete
def jobName = "Your Job Name"
def job = Jenkins.instance.getItem(jobName)

job.getBuilds().each { it.delete() }
// uncomment these lines to reset the build number to 1:
//job.nextBuildNumber = 1
//job.save()

Though one can build a progress bar using setInterval and animating its width

For best performance while animating a progress bar one has to take into account compositor only properties and manage layer count.

Here is an example:

function update(e){_x000D_
  var left = e.currentTarget.offsetLeft;_x000D_
  var width = e.currentTarget.offsetWidth_x000D_
  var position = Math.floor((e.pageX - left) / width * 100) + 1;_x000D_
  var bar = e.currentTarget.querySelector(".progress-bar__bar");_x000D_
  bar.style.transform = 'translateX(' + position + '%)';_x000D_
}

body {_x000D_
  padding: 2em;_x000D_
}_x000D_
_x000D_
.progress-bar {_x000D_
  cursor: pointer;_x000D_
  margin-bottom: 10px;_x000D_
  user-select: none;_x000D_
}_x000D_
_x000D_
.progress-bar {_x000D_
  background-color: #669900;_x000D_
  border-radius: 4px;_x000D_
  box-shadow: inset 0 0.5em 0.5em rgba(0, 0, 0, 0.05);_x000D_
  height: 20px;_x000D_
  margin: 10px;_x000D_
  overflow: hidden;_x000D_
  position: relative;_x000D_
  transform: translateZ(0);_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
.progress-bar__bar {_x000D_
  background-color: #ececec;_x000D_
  box-shadow: inset 0 0.5em 0.5em rgba(0, 0, 0, 0.05);_x000D_
  bottom: 0;_x000D_
  left: 0;_x000D_
  position: absolute;_x000D_
  right: 0;_x000D_
  top: 0;_x000D_
  transition: all 500ms ease-out;_x000D_
}

Click on progress bar to update value_x000D_
_x000D_
<div class="progress-bar" onclick="update(event)">_x000D_
  <div class="progress-bar__bar"></div>_x000D_
</div>

As Wingman said, Google App Engine is a great solution for your scenario.

You can get some information about GAE+Android here: https://developers.google.com/eclipse/docs/appengine_connected_android

thanks, try this instead

Select

I'm happy to help you

Tested code, initially creates a single archive file, then splits it:

 gzip -c file.orig > file.gz
 CHUNKSIZE=1073741824
 PARTCNT=$[$(stat -c%s file.gz) / $CHUNKSIZE]

 # the remainder is taken care of, for example for
 # 1 GiB + 1 bytes PARTCNT is 1 and seq 0 $PARTCNT covers
 # all of file
 for n in `seq 0 $PARTCNT`
 do
       dd if=file.gz of=part.$n bs=$CHUNKSIZE skip=$n count=1
 done

This variant omits creating a single archive file and goes straight to creating parts:

gzip -c file.orig |
    ( CHUNKSIZE=1073741824;
        i=0;
        while true; do
            i=$[i+1];
            head -c "$CHUNKSIZE" > "part.$i";
            [ "$CHUNKSIZE" -eq $(stat -c%s "part.$i") ] || break;
        done; )

In this variant, if the archive's file size is divisible by $CHUNKSIZE, then the last partial file will have file size 0 bytes.

doThrow : Basically used when you want to throw an exception when a method is being called within a mock object.

public void validateEntity(final Object object){}
Mockito.doThrow(IllegalArgumentException.class)
.when(validationService).validateEntity(Matchers.any(AnyObjectClass.class));

doReturn : Used when you want to send back a return value when a method is executed.

public Socket getCosmosSocket() throws IOException {}
Mockito.doReturn(cosmosSocket).when(cosmosServiceImpl).getCosmosSocket();

doAnswer: Sometimes you need to do some actions with the arguments that are passed to the method, for example, add some values, make some calculations or even modify them doAnswer gives you the Answer interface that being executed in the moment that method is called, this interface allows you to interact with the parameters via the InvocationOnMock argument. Also, the return value of answer method will be the return value of the mocked method.

public ReturnValueObject quickChange(Object1 object);
Mockito.doAnswer(new Answer<ReturnValueObject>() {

        @Override
        public ReturnValueObject answer(final InvocationOnMock invocation) throws Throwable {

            final Object1 originalArgument = (invocation.getArguments())[0];
            final ReturnValueObject returnedValue = new ReturnValueObject();
            returnedValue.setCost(new Cost());

            return returnedValue ;
        }
}).when(priceChangeRequestService).quickCharge(Matchers.any(Object1.class));

doNothing: Is the easiest of the list, basically it tells Mockito to do nothing when a method in a mock object is called. Sometimes used in void return methods or method that does not have side effects, or are not related to the unit testing you are doing.

public void updateRequestActionAndApproval(final List<Object1> cmItems);

Mockito.doNothing().when(pagLogService).updateRequestActionAndApproval(
                Matchers.any(Object1.class));

readlines() will return a list of all the lines in the file, so lines is a list. You probably want something like this:

for line in f.readlines(): # Iterates through every line and looks for a match
#or
#for line in f:
    match = re.findall('[A-Z]+', line)
    print match

Or, if the file isn't too large you can grab it as as single string:

lines = f.read() # Warning: reads the FULL FILE into memory. This can be bad.
match = re.findall('[A-Z]+', lines)
print match

As some people already said that it is not possible to prevent people to download your pictures, a trick could be something like this:

$(document).ready(function()
{
    $('img').bind('contextmenu', function(e){
        return false;
    }); 
});

This trick prevents from the right click on all img. Obviously people can open the source code and download the images using links in your source code.

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

<input type="hidden" name="id" value="" id="id">

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });
    });
    </script>

Pretty simple but another said you dont pass session variables through the url bar 1.You dont need to because a session is passed throughout the whole website from header when you put in header file 2.security risks
Here is first page code

$url = "http://localhost/main.php?email=" . urlencode($email_address) . "&eventid=" . urlencode($event_id);

2nd page when getting the variables from the url bar is:

if(isset($_GET['email']) && !empty($_GET['email']) AND isset($_GET['eventid']) && !empty($_GET['eventid'])){ ////do whatever here }

Now if you want to do it the proper way of using the session you created then ignore my above code and call the session variables on the second page for instance create a session on the first page lets say for example:

 $_SESSION['WEB_SES'] = $email_address . "^" . $event_id;

obvious that you would have already assigned values to the session variables in the code above, you can call the session name whatever you want to i just used the example web_ses , the second page all you need to do is start a session and see if the session is there and check the variables and do whatever with them, example:

 session_start();
 if (isset($_SESSION['WEB_SES'])){
 $Array = explode("^", $_SESSION['WEB_SES']);
 $email = $Array[0];
 $event_id = $Array[1]
 echo "$email";
 echo "$event_id";
 }

Like I said before the good thing about sessions are they can be carried throughout the entire website if this type of code in put in the header file that gets called upon on all pages that load, you can simple use the variable wherever and whenever. Hope this helps :)

If you are looking for an alternative way, try adding your credentials using AmazonCLI

from the terminal type:-

aws configure

then fill in your keys and region.

Configure The "php.ini" File

First, ensure that PHP is configured to allow file uploads. In your "php.ini" file, search for the file_uploads directive, and set it to On:

file_uploads = On 

Create The HTML Form

Next, create an HTML form that allow users to choose the image file they want to upload:

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

Some rules to follow for the HTML form above: Make sure that the form uses method="post" The form also needs the following attribute: enctype="multipart/form-data". It specifies which content-type to use when submitting the form Without the requirements above, the file upload will not work. Other things to notice: The type="file" attribute of the tag shows the input field as a file-select control, with a "Browse" button next to the input control The form above sends data to a file called "upload.php", which we will create next.

Create The Upload File PHP Script

The "upload.php" file contains the code for uploading a file:

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
?>

When using a factory your code is still actually responsible for creating objects. By DI you outsource that responsibility to another class or a framework, which is separate from your code.

Quoted from https://developer.mozilla.org/en/DOM/element.click

The click method is intended to be used with INPUT elements of type button, checkbox, radio, reset or submit. Gecko does not implement the click method on other elements that might be expected to respond to mouse–clicks such as links (A elements), nor will it necessarily fire the click event of other elements.

Non–Gecko DOMs may behave differently.

Unfortunately it sounds like you have already discovered the best solution to your problem.

As a side note, I agree that your solution seems less than ideal, but if you encapsulate the functionality inside a method (much like JQuery would do) it is not so bad.

Use the wildcard "#" but beware that at some point you will have to somehow understand the data passing through the bus!

Surrounding the path and the argument with spaces inside quotes as in your example should do. The command may need to handle the quotes when the parameters are passed to it, but it usually is not a big deal.

How about the Mersenne Twister? The boost implementation is rather easy to use and is well tested in many real-world applications. I've used it myself in several academic projects such as artificial intelligence and evolutionary algorithms.

Here's their example where they make a simple function to roll a six-sided die:

#include <boost/random/mersenne_twister.hpp>
#include <boost/random/uniform_int.hpp>
#include <boost/random/variate_generator.hpp>

boost::mt19937 gen;

int roll_die() {
    boost::uniform_int<> dist(1, 6);
    boost::variate_generator<boost::mt19937&, boost::uniform_int<> > die(gen, dist);
    return die();
}

Oh, and here's some more pimping of this generator just in case you aren't convinced you should use it over the vastly inferior rand():

The Mersenne Twister is a "random number" generator invented by Makoto Matsumoto and Takuji Nishimura; their website includes numerous implementations of the algorithm.

Essentially, the Mersenne Twister is a very large linear-feedback shift register. The algorithm operates on a 19,937 bit seed, stored in an 624-element array of 32-bit unsigned integers. The value 2^19937-1 is a Mersenne prime; the technique for manipulating the seed is based on an older "twisting" algorithm -- hence the name "Mersenne Twister".

An appealing aspect of the Mersenne Twister is its use of binary operations -- as opposed to time-consuming multiplication -- for generating numbers. The algorithm also has a very long period, and good granularity. It is both fast and effective for non-cryptographic applications.

If you are targeting SDK > 21 (lollipop or 5.0) use

context.getDrawable(R.drawable.your_drawable_name)

See docs

Seems to me that the right formula should be:

n64 = 4 * (n / 3) + (n % 3 != 0 ? 4 : 0)

You could use something like this:

Private Sub PrintTableOrView(ByVal table As DataTable, ByVal label As String)
    Dim sw As System.IO.StringWriter
    Dim output As String

    Console.WriteLine(label)

    ' Loop through each row in the table. '
    For Each row As DataRow In table.Rows
        sw = New System.IO.StringWriter
        ' Loop through each column. '
        For Each col As DataColumn In table.Columns
            ' Output the value of each column's data.
            sw.Write(row(col).ToString() & ", ")
        Next
        output = sw.ToString
        ' Trim off the trailing ", ", so the output looks correct. '
        If output.Length > 2 Then
            output = output.Substring(0, output.Length - 2)
        End If
        ' Display the row in the console window. '
        Console.WriteLine(output)
    Next
    Console.WriteLine()
End Sub

If undocumented features aren't your game, the same can be accomplished here:

Handlebars.registerHelper('index_of', function(context,ndx) {
  return context[ndx];
});

Then in a template

{{#index_of this 1}}{{/index_of}}   

I wrote the above before I got a hold of

this.[0]

I can't see one getting too far with handlebars without writing your own helpers.

I would do something like:

$(documento).on('click', '#answer', function() {
  feedback('hey there');
});

A global variable would be best expressed in an external JavaScript file:

var system_status;

Make sure that this has not been used anywhere else. Then to access the variable on your page, just reference it as such. Say, for example, you wanted to fill in the results on a textbox,

document.getElementById("textbox1").value = system_status;

To ensure that the object exists, use the document ready feature of jQuery.

Example:

$(function() {
    $("#textbox1")[0].value = system_status;
});

apue.h dependency was still missing in my /usr/local/include after I managed to fix this problem on Mac OS Catalina following the instructions of this answer

I downloaded the dependency manually from git and placed it in /usr/local/include

Please try running

brew install docker

This will install the Docker engine, which will require Docker-Machine (+ VirtualBox) to run on the Mac.

If you want to install the newer Docker for Mac, which does not require virtualbox, you can install that through Homebrew's Cask:

brew install --cask docker 
open /Applications/Docker.app

select * 
from tempdb.INFORMATION_SCHEMA.COLUMNS 
where TABLE_NAME=OBJECT_NAME(OBJECT_ID('#table'))

Firebug is one of the most popular tools for this purpose.

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr variable at compile time, knowing that the difference between constexpr and static constexpr is that to use static constexpr you ensure the variable is initialized only once.

Following code demonstrates how constexpr variable is initialized multiple times (with same value though), while static constexpr is surely initialized only once.

In addition the code compares the advantage of constexpr against const in combination with static.

#include <iostream>
#include <string>
#include <cassert>
#include <sstream>

const short const_short = 0;
constexpr short constexpr_short = 0;

// print only last 3 address value numbers
const short addr_offset = 3;

// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
    // determine initial size of strings
    std::string title = "value \\ address of ";
    const size_t ref_size = ref_name.size();
    const size_t title_size = title.size();
    assert(title_size > ref_size);

    // create title (resize)
    title.append(ref_name);
    title.append(" is ");
    title.append(title_size - ref_size, ' ');

    // extract last 'offset' values from address
    std::stringstream addr;
    addr << param;
    const std::string addr_str = addr.str();
    const size_t addr_size = addr_str.size();
    assert(addr_size - offset > 0);

    // print title / ref value / address at offset
    std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}

// here we test initialization of const variable (runtime)
void const_value(const short counter)
{
    static short temp = const_short;
    const short const_var = ++temp;
    print_properties("const", &const_var, addr_offset);

    if (counter)
        const_value(counter - 1);
}

// here we test initialization of static variable (runtime)
void static_value(const short counter)
{
    static short temp = const_short;
    static short static_var = ++temp;
    print_properties("static", &static_var, addr_offset);

    if (counter)
        static_value(counter - 1);
}

// here we test initialization of static const variable (runtime)
void static_const_value(const short counter)
{
    static short temp = const_short;
    static const short static_var = ++temp;
    print_properties("static const", &static_var, addr_offset);

    if (counter)
        static_const_value(counter - 1);
}

// here we test initialization of constexpr variable (compile time)
void constexpr_value(const short counter)
{
    constexpr short constexpr_var = constexpr_short;
    print_properties("constexpr", &constexpr_var, addr_offset);

    if (counter)
        constexpr_value(counter - 1);
}

// here we test initialization of static constexpr variable (compile time)
void static_constexpr_value(const short counter)
{
    static constexpr short static_constexpr_var = constexpr_short;
    print_properties("static constexpr", &static_constexpr_var, addr_offset);

    if (counter)
        static_constexpr_value(counter - 1);
}

// final test call this method from main()
void test_static_const()
{
    constexpr short counter = 2;

    const_value(counter);
    std::cout << std::endl;

    static_value(counter);
    std::cout << std::endl;

    static_const_value(counter);
    std::cout << std::endl;

    constexpr_value(counter);
    std::cout << std::endl;

    static_constexpr_value(counter);
    std::cout << std::endl;
}

Possible program output:

value \ address of const is               1 564
value \ address of const is               2 3D4
value \ address of const is               3 244

value \ address of static is              1 C58
value \ address of static is              1 C58
value \ address of static is              1 C58

value \ address of static const is        1 C64
value \ address of static const is        1 C64
value \ address of static const is        1 C64

value \ address of constexpr is           0 564
value \ address of constexpr is           0 3D4
value \ address of constexpr is           0 244

value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0

As you can see yourself constexpr is initilized multiple times (address is not the same) while static keyword ensures that initialization is performed only once.

Similarly using rlang:

eval(parse_expr("5+5"))

You can use the key parameter to list.sort():

my_list.sort(key=lambda x: x[1])

or, slightly faster,

my_list.sort(key=operator.itemgetter(1))

(As with any module, you'll need to import operator to be able to use it.)

Alternatively you can execute program with specified library dir:

/lib/ld-linux.so.2 --library-path PATH EXECUTABLE

const T and T const are identical. With pointer types it becomes more complicated:

1. const char* is a pointer to a constant char
2. char const* is a pointer to a constant char
3. char* const is a constant pointer to a (mutable) char

In other words, (1) and (2) are identical. The only way of making the pointer (rather than the pointee) const is to use a suffix-const.

This is why many people prefer to always put const to the right side of the type (“East const” style): it makes its location relative to the type consistent and easy to remember (it also anecdotally seems to make it easier to teach to beginners).

You need some JS to achieve this by simply adding alert('Your message') within your PHP code.

See example below

     <?php 

//my other php code here
        
        function function_alert() { 
              
            // Display the alert box; note the Js tags within echo, it performs the magic
            echo "<script>alert('Your message Here');</script>"; 
        } 
        
        ?> 

when you visit your browser using the route supposed to triger your function_alert, you will see the alert box with your message displayed on your screen.

SIMPLE XML EXAMPLE:

<school>
  <firstname>John</firstname>
  <lastname>Smith</lastname>
</school>

XSD OF ABOVE XML(Explained):

<xs:element name="school">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="firstname" type="xs:string"/>
      <xs:element name="lastname" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

Here:

xs:element : Defines an element.

xs:sequence : Denotes child elements only appear in the order mentioned.

xs:complexType : Denotes it contains other elements.

xs:simpleType : Denotes they do not contain other elements.

type: string, decimal, integer, boolean, date, time,

• In simple words, xsd is another way to represent and validate XML data with the specific type.

• With the help of extra attributes, we can perform multiple operations.

• Performing any task on xsd is simpler than xml.

Assuming your table of data is called ProjectInfo:

SELECT DISTINCT Contract, Activity
    FROM ProjectInfo
    WHERE Contract = (SELECT Contract
                          FROM (SELECT DISTINCT Contract, Activity
                                    FROM ProjectInfo) AS ContractActivities
                          GROUP BY Contract
                          HAVING COUNT(*) = 1);

The innermost query identifies the contracts and the activities. The next level of the query (the middle one) identifies the contracts where there is just one activity. The outermost query then pulls the contract and activity from the ProjectInfo table for the contracts that have a single activity.

Tested using IBM Informix Dynamic Server 11.50 - should work elsewhere too.

I had the same issue, I found most of the answers here out dated. I ended up writing a wrapper on FFMPEG to access from Android with a single line of code.

https://github.com/madhavanmalolan/ffmpegandroidlibrary

Multiple columns in a key are going to, in general, perform more poorly than a surrogate key. I prefer to have a surrogate key and then a unique index on a multicolumn key. That way you can have better performance and the uniqueness needed is maintained. And even better, when one of the values in that key changes, you don't also have to update a million child entries in 215 child tables.

This VBA code will refresh all pivot tables/charts in the workbook.

Sub RefreshAllPivotTables()

Dim PT As PivotTable
Dim WS As Worksheet

    For Each WS In ThisWorkbook.Worksheets

        For Each PT In WS.PivotTables
          PT.RefreshTable
        Next PT

    Next WS

End Sub

Another non-programatic option is:

• Right click on each pivot table
• Select Table options
• Tick the 'Refresh on open' option.
• Click on the OK button

This will refresh the pivot table each time the workbook is opened.

For macOS with zshrc:

ANDROID_HOME is depreciated, use ANDROID_SDK_ROOT instead

1. Ensure that Android Build Tools is installed. Check if it exists in your File Directory
2. Get the path to your SDK. Usually it is /Users/<USER>/Library/Android/sdk
3. Add ANDROID_SDK_ROOT as a path to your Environment variables: echo 'export ANDROID_SDK_ROOT=/Users/<USER>/Library/Android/sdk' >> ~/.zshenv
4. Apply the changes with source ~/.zshrc
5. Check if it was saved by ...
   • ... checking the specific environment variable echo $ANDROID_SDK_ROOT
   • ... checking the complete list of environment variables on your system env

You can apply this process to every environment variable beeing installed on your macOS system. It took me a while to comprehend it for myself

Here what i did, it works fine.

step 1:(it lists docker container with its name)

docker ps -a

step 2:

docker rm name_of_the_docker_container

For unit test:

spyOn(component.form, 'valid').and.returnValue(true);

Nothing. The sole difference between the types is their size (and, hence, the range of values they can represent).

try this one its worked for me

$(document).ready(function(e){_x000D_
        $.ajax({_x000D_
           url:"fetch",_x000D_
           processData: false,_x000D_
           dataType:"json",_x000D_
           type: 'POST',_x000D_
           cache: false,_x000D_
           success: function (data, textStatus, jqXHR) {_x000D_
                        _x000D_
                         $.each(data.Table,function(i,tweet){_x000D_
      $("#list").append('<option value="'+tweet.actor_id+'">'+tweet.first_name+'</option>');_x000D_
   });}_x000D_
        });_x000D_
    });

I encountered the same error message but don't have any access to the table like "dba_free_space" because I am not a dba. I use some previous answers to check available space and I still have a lot of space. However, after reducing the full table scan as many as possible. The problem is solved. My guess is that Oracle uses temp table to store the full table scan data. It the data size exceeds the limit, it will show the error. Hope this helps someone with the same issue

pow is built into the language(not part of the math library). The problem is that you haven't imported math.

Try this:

import math
math.sqrt(4)

In my case problem was in using PowerShell instead of CMD :)

Here is how I did mine: if you use npx create-react-app to set up you react, you need to import the image from its folder in the Component where you want to use it. It's just the way you import other modules from their folders.

So, you need to write:

import myImage from './imageFolder/imageName'

Then in your JSX, you can have something like this: <image src = {myImage} />

See it in the screenshot below:

Use the return keyword to exit from a method.

public void someMethod() {
    //... a bunch of code ...
    if (someCondition()) {
        return;
    }
    //... otherwise do the following...
}

From the Java Tutorial that I linked to above:

Any method declared void doesn't return a value. It does not need to contain a return statement, but it may do so. In such a case, a return statement can be used to branch out of a control flow block and exit the method and is simply used like this:

return;

You don't need to add '.' in your class name. This will do

document.getElementsByClassName('col1')

Additionally, since you haven't define the background color via javascript, you won't able to call it directly. You have to use window.getComputedStyle() or jquery to achieve what you are trying to do above.

Here is a working example

http://jsfiddle.net/J9LU8/

try this:

legend.green-color a:hover{
    text-decoration: none;
}

Do you need the cursor to be a "wait" cursor only when it's over that particular page/usercontrol? If not, I'd suggest using Mouse.OverrideCursor:

Mouse.OverrideCursor = Cursors.Wait;
try
{
    // do stuff
}
finally
{
    Mouse.OverrideCursor = null;
}

This overrides the cursor for your application rather than just for a part of its UI, so the problem you're describing goes away.

It's worth noting that if you want to sort particular properties descending, you don't want to simply append .reverse() at the end, as this will make all of the sorts descending.

To make particular sorts descending, chain your sorts from least significant to most significant, calling .reverse() after each sort that you want to be descending.

var data = _(data).chain()
    .sort("date")
    .reverse()    // sort by date descending
    .sort("name") // sort by name ascending
    .result()

Since _'s sort is a stable sort, you can safely chain and reverse sorts because if two items have the same value for a property, their order is preserved.

I've just knocked this up on reading this thread (because it's what I was needing too). I have Pythons 2.6.1 and 3.0.1 on both Ubuntu and Windows. If it doesn't work for you post fixes here.

The vimrc file in Ubuntu (12.04 (Precise Pangolin)): I tried :scriptnames in Vim, and it shows both /usr/share/vim/vimrc and ~/.vimrc.

But I had manually created ~/.vimrc.

I'd say vim is definitely worth learning. I picked it up last summer, and it is now my editor of choice for just about everything (java is a stretch, but doable when I don't need extensive analysis support). As everyone has already affirmed, it is a wonderfully efficient tool.

For what it's worth, I only learned a fairly small subset of vim's features (which took a day or two) from a graphical tutorial, and a few odds and ends from here (long read), and the search and replace functionality, and I was hooked. I've learned things since then, but at my leisure. I'd say the learning curve flattens out at this point, but then, I was using it pretty heavily and was surrounded by others who were, too.

ooh! neat question.

Matlab's for loop takes a matrix as input and iterates over its columns. Matlab also handles practically everything by value (no pass-by-reference) so I would expect that it takes a snapshot of the for-loop's input so it's immutable.

here's an example which may help illustrate:

>> A = zeros(4); A(:) = 1:16

A =

     1     5     9    13
     2     6    10    14
     3     7    11    15

This code generates some SQL which can achieve this on every table and column in the database:

FROM 
    INFORMATION_SCHEMA.columns C
INNER JOIN
    INFORMATION_SCHEMA.TABLES T ON C.TABLE_NAME=T.TABLE_NAME AND C.TABLE_SCHEMA=T.TABLE_SCHEMA
WHERE

As pointed out by Martijn, glob can only do this through the **operator introduced in Python 3.5. Since the OP explicitly asked for the glob module, the following will return a lazy evaluation iterator that behaves similarly

import os, glob, itertools

configfiles = itertools.chain.from_iterable(glob.iglob(os.path.join(root,'*.txt'))
                         for root, dirs, files in os.walk('C:/Users/sam/Desktop/file1/'))

Note that you can only iterate once over configfiles in this approach though. If you require a real list of configfiles that can be used in multiple operations you would have to create this explicitly by using list(configfiles).

Generally speaking, this is the configuration file of web applications in java. It instructs the servlet container (tomcat for ex.) which classes to load, what parameters to set in the context, and how to intercept requests coming from browsers.

There you specify:

• what servlets (and filters) you want to use and what URLs you want to map them to
• listeners - classes that are notified when some events happen (context starts, session created, etc)
• configuration parameters (context-params)
• error pages, welcome files
• security constraints

In servlet 3.0 many of the web.xml parts are optional. These configurations can be done via annotations (@WebServlet, @WebListener)

It looks like it only works in Internet Explorer, but a quick Google search for "html embed fonts" yields http://www.spoono.com/html/tutorials/tutorial.php?id=19

If you want to stay platform-agnostic (and you should!) you'll have to use images, or else just use a standard font.

I faced the same issue when I was creating Docker images from Jenkins. Simply add the user to the docker group and then restart Docker services and in my case I had to restart Jenkins services.

This was the error which I got:

I threw together a small test implementation of this. The basic idea is to call format and pass in the format string, and a map of objects, and the names that they have locally.

The output of the following is:

My dog is named fido, and Jane Doe owns him.

public class StringFormatter {

    private static final String fieldStart = "\\$\\{";
    private static final String fieldEnd = "\\}";

    private static final String regex = fieldStart + "([^}]+)" + fieldEnd;
    private static final Pattern pattern = Pattern.compile(regex);

    public static String format(String format, Map<String, Object> objects) {
        Matcher m = pattern.matcher(format);
        String result = format;
        while (m.find()) {
            String[] found = m.group(1).split("\\.");
            Object o = objects.get(found[0]);
            Field f = o.getClass().getField(found[1]);
            String newVal = f.get(o).toString();
            result = result.replaceFirst(regex, newVal);
        }
        return result;
    }

    static class Dog {
        public String name;
        public String owner;
        public String gender;
    }

    public static void main(String[] args) {
        Dog d = new Dog();
        d.name = "fido";
        d.owner = "Jane Doe";
        d.gender = "him";
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("d", d);
        System.out.println(
           StringFormatter.format(
                "My dog is named ${d.name}, and ${d.owner} owns ${d.gender}.", 
                map));
    }
}

Note: This doesn't compile due to unhandled exceptions. But it makes the code much easier to read.

Also, I don't like that you have to construct the map yourself in the code, but I don't know how to get the names of the local variables programatically. The best way to do it, is to remember to put the object in the map as soon as you create it.

The following example produces the results that you want from your example:

public static void main(String[] args) {
    Map<String, Object> map = new HashMap<String, Object>();
    Site site = new Site();
    map.put("site", site);
    site.name = "StackOverflow.com";
    User user = new User();
    map.put("user", user);
    user.name = "jjnguy";
    System.out.println(
         format("Hello ${user.name},\n\tWelcome to ${site.name}. ", map));
}

_{I should also mention that I have no idea what Velocity is, so I hope this answer is relevant.}

That is a very open apples-to-oranges type of question.

You are asking 1. the average request load for a production application 2. what is considered fast

These don't neccessarily relate.

Your average # of requests per second is determined by

a. the number of simultaneous users

b. the average number of page requests they make per second

c. the number of additional requests (i.e. ajax calls, etc)

As to what is considered fast.. do you mean how few requests a site can take? Or if a piece of hardware is considered fast if it can process xyz # of requests per second?

The rules for new are analogous to what happens when you initialize an object with automatic storage duration (although, because of vexing parse, the syntax can be slightly different).

If I say:

int my_int; // default-initialize ? indeterminate (non-class type)

Then my_int has an indeterminate value, since it is a non-class type. Alternatively, I can value-initialize my_int (which, for non-class types, zero-initializes) like this:

int my_int{}; // value-initialize ? zero-initialize (non-class type)

(Of course, I can't use () because that would be a function declaration, but int() works the same as int{} to construct a temporary.)

Whereas, for class types:

Thing my_thing; // default-initialize ? default ctor (class type)
Thing my_thing{}; // value-initialize ? default-initialize ? default ctor (class type)

The default constructor is called to create a Thing, no exceptions.

So, the rules are more or less:

• Is it a class type?
  • YES: The default constructor is called, regardless of whether it is value-initialized (with {}) or default-initialized (without {}). (There is some additional prior zeroing behavior with value-initialization, but the default constructor is always given the final say.)
  • NO: Were {} used?
    • YES: The object is value-initialized, which, for non-class types, more or less just zero-initializes.
    • NO: The object is default-initialized, which, for non-class types, leaves it with an indeterminate value (it effectively isn't initialized).

These rules translate precisely to new syntax, with the added rule that () can be substituted for {} because new is never parsed as a function declaration. So:

int* my_new_int = new int; // default-initialize ? indeterminate (non-class type)
Thing* my_new_thing = new Thing; // default-initialize ? default ctor (class type)
int* my_new_zeroed_int = new int(); // value-initialize ? zero-initialize (non-class type)
     my_new_zeroed_int = new int{}; // ditto
       my_new_thing = new Thing(); // value-initialize ? default-initialize ? default ctor (class type)

(This answer incorporates conceptual changes in C++11 that the top answer currently does not; notably, a new scalar or POD instance that would end up an with indeterminate value is now technically now default-initialized (which, for POD types, technically calls a trivial default constructor). While this does not cause much practical change in behavior, it does simplify the rules somewhat.)

1. Declare object of EditText on top of class:

    EditText myEditText;
   

2. Find EditText in onCreate Function and setOnFocusChangeListener of EditText:

   myEditText = findViewById(R.id.yourEditTextNameInxml); 
   
   myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
               @Override
               public void onFocusChange(View view, boolean hasFocus) {
                   if (!hasFocus) {
                        Toast.makeText(this, "Focus Lose", Toast.LENGTH_SHORT).show();
                   }else{
                       Toast.makeText(this, "Get Focus", Toast.LENGTH_SHORT).show();
                   }
   
               }
           });
   

It works fine.

I had similar situation and here is my approach which is somewhat different:

 HADOOP_USER_NAME=hdfs hdfs dfs -put /root/MyHadoop/file1.txt /

What you actually do is you read local file in accordance to your local permissions but when placing file on HDFS you are authenticated like user hdfs. You can do this with other ID (beware of real auth schemes configuration but this is usually not a case).

Advantages:

1. Permissions are kept on HDFS.
2. You don't need sudo.
3. You don't need actually appropriate local user 'hdfs' at all.
4. You don't need to copy anything or change permissions because of previous points.

If the goal is to be able to push to a GitHub repo whenever you want to, then in Windows under C:\Users\tiago\.ssh where the keys are stored (at least in my case), create a file named config and add the following in it

Host github.com
    HostName github.com
    User your_user_name
    IdentityFile ~/.ssh/your_file_name

Then simply open Git Bash and you'll be able to push without having to manually start the ssh-agent and adding the key.
