You can simply pass the functions as a list:

In [20]: df.groupby("dummy").agg({"returns": [np.mean, np.sum]})
Out[20]:         
           mean       sum
dummy                    
1      0.036901  0.369012

or as a dictionary:

In [21]: df.groupby('dummy').agg({'returns':
                                  {'Mean': np.mean, 'Sum': np.sum}})
Out[21]: 
        returns          
           Mean       Sum
dummy                    
1      0.036901  0.369012

I have traversed hundred of pages, googled a lot but i have not found any exact solution. Finally this worked for me. Irrespective where you are in either controller or model. This code worked for me every where. Just use this

//Before executing your query
$db = Zend_Db_Table_Abstract::getDefaultAdapter();
$db->getProfiler()->setEnabled(true);
$profiler = $db->getProfiler();

// Execute your any of database query here like select, update, insert
//The code below must be after query execution
$query  = $profiler->getLastQueryProfile();
$params = $query->getQueryParams();
$querystr  = $query->getQuery();

foreach ($params as $par) {
    $querystr = preg_replace('/\\?/', "'" . $par . "'", $querystr, 1);
}
echo $querystr;

Finally this thing worked for me.

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

I'm using window.location.reload(true) according to MDN (and this similar question) it forces page to reload from server.

You can execute this code in the browser by typing javascript:location.reload(true) in the address bar.

And if you are using python 3.X, you may apply the sorted function on the mylist. This is just an addition to the answer that @Sven Marnach has given above.

# using *sort method*
mylist.sort(lambda x: x[1]) 

# using *sorted function*
sorted(mylist, key = lambda x: x[1]) 

You are using DictWriter.writerows() which expects a list of dicts, not a dict. You want DictWriter.writerow() to write a single row.

You will also want to use DictWriter.writeheader() if you want a header for you csv file.

You also might want to check out the with statement for opening files. It's not only more pythonic and readable but handles closing for you, even when exceptions occur.

Example with these changes made:

import csv

my_dict = {"test": 1, "testing": 2}

with open('mycsvfile.csv', 'w') as f:  # You will need 'wb' mode in Python 2.x
    w = csv.DictWriter(f, my_dict.keys())
    w.writeheader()
    w.writerow(my_dict)

Which produces:

test,testing
1,2

Something like this should do it:

for element in list_:
   sys.stdout.write(str(element))

$ck=2016-09-13 14:12:33;
$endtime = date('H-i-s', strtotime("+05 minutes", strtotime($ck)));  

Try git fetch --dry-run The manual (git help fetch) says:

--dry-run
Show what would be done, without making any changes.

The trim() method removes whitespace from both sides of a string.

To remove all the spaces from the string use .replace(/\s/g, "")

 this.maintabinfo = this.inner_view_data.replace(/\s/g, "").toLowerCase();

As long as your List is a concrete class, you can simply call the contains() method as long as you have implemented your equals() method on MyItem.

// given 
// some input ... you to complete

// when
List<MyItems> results = service.getMyItems();

// then
assertTrue(results.contains(new MyItem("foo")));
assertTrue(results.contains(new MyItem("bar")));

Assumes you have implemented a constructor that accepts the values you want to assert on. I realise this isn't on a single line, but it's useful to know which value is missing rather than checking both at once.

Given its name, I think the standard way should be delete:

import numpy as np

A = np.delete(A, 1, 0)  # delete second row of A
B = np.delete(B, 2, 0)  # delete third row of B
C = np.delete(C, 1, 1)  # delete second column of C

According to numpy's documentation page, the parameters for numpy.delete are as follow:

numpy.delete(arr, obj, axis=None)

• arr refers to the input array,
• obj refers to which sub-arrays (e.g. column/row no. or slice of the array) and
• axis refers to either column wise (axis = 1) or row-wise (axis = 0) delete operation.

Cannot say about the "official nomenclature" - infact I wonder whose word will be "official" anyway - but here's how they can be called:

• Horizontal stripes : Hamburger menu / icon / button -> -> as per wiki. A name like "sandwich button" would also have been good IMO :(
• Vertical ellipsis : Dango menu / icon / button -> -> credits to this guy. This one I like thanks to the song from the super duper anime Clannad

I can offer two options

1. Direct copy

Based on your description I'm guessing you are doing something like

Set wb2 = Application.Workbooks.Open("YourFile.xls")
wb2.Sheets("YourSheet").[<YourRange>].Copy
ThisWorkbook.Sheets("SomeSheet").Paste
wb2.close

If this is the case, you don't need to copy via the clipboard. This method copies from source to destination directly. No data in clipboard = no prompt

Set wb2 = Application.Workbooks.Open("YourFile.xls")
wb2.Sheets("YourSheet").[<YourRange>].Copy ThisWorkbook.Sheets("SomeSheet").Cells(<YourCell")
wb2.close

2. Suppress prompt

You can prevent all alert pop-ups by setting

Application.DisplayAlerts = False

[Edit]

3. To copy values only: don't use copy/paste at all

Dim rSrc As Range
Dim rDst As Range
Set rSrc = wb2.Sheets("YourSheet").Range("YourRange")
Set rDst = ThisWorkbook.Sheets("SomeSheet").Cells("YourCell").Resize(rSrc.Rows.Count, rSrc.Columns.Count)
rDst = rSrc.Value

Real power comes with understanding and implementation membership provider together with role provider. You can assign users into roles and according to that restriction you can apply different access roles for different user to controller actions or controller itself.

 [Authorize(Users = "Betty, Johnny")]
 public ActionResult SpecificUserOnly()
 {
     return View();
 }

or you can restrict according to group

[Authorize(Roles = "Admin, Super User")]
public ActionResult AdministratorsOnly()
{
    return View();
}

var groups = list.GroupBy(x => x.ID);

Can anybody suggest how to get the values (List) from an IGrouping<int, smth> in such a context?

"IGrouping<int, smth> group" is actually an IEnumerable with a key, so you either:

• iterate on the group or
• use group.ToList() to convert it to a List

foreach (IGrouping<int, smth> group in groups)
{
   var thisIsYourGroupKey = group.Key; 
   List<smth> list = group.ToList();     // or use directly group.foreach
}

From the research I have done, if you are targeting Nvidia GPUs and have decided to use CUDA over OpenCL, I found three ways to use the CUDA API in java.

1. JCuda (or alternative)- http://www.jcuda.org/. This seems like the best solution for the problems I am working on. Many of libraries such as CUBLAS are available in JCuda. Kernels are still written in C though.
2. JNI - JNI interfaces are not my favorite to write, but are very powerful and would allow you to do anything CUDA can do.
3. JavaCPP - This basically lets you make a JNI interface in Java without writing C code directly. There is an example here: What is the easiest way to run working CUDA code in Java? of how to use this with CUDA thrust. To me, this seems like you might as well just write a JNI interface.

All of these answers basically are just ways of using C/C++ code in Java. You should ask yourself why you need to use Java and if you can't do it in C/C++ instead.

If you like Java and know how to use it and don't want to work with all the pointer management and what-not that comes with C/C++ then JCuda is probably the answer. On the other hand, the CUDA Thrust library and other libraries like it can be used to do a lot of the pointer management in C/C++ and maybe you should look at that.

If you like C/C++ and don't mind pointer management, but there are other constraints forcing you to use Java, then JNI might be the best approach. Though, if your JNI methods are just going be wrappers for kernel commands you might as well just use JCuda.

There are a few alternatives to JCuda such as Cuda4J and Root Beer, but those do not seem to be maintained. Whereas at the time of writing this JCuda supports CUDA 10.1. which is the most up-to-date CUDA SDK.

Additionally there are a few java libraries that use CUDA, such as deeplearning4j and Hadoop, that may be able to do what you are looking for without requiring you to write kernel code directly. I have not looked into them too much though.

var toMatch = "john w. smith";
var result = toMatch.replace(/(\w)(\w*)/g, function (_, i, r) {
      return i.toUpperCase() + (r != null ? r : "");
    }
)

Seems to work... Tested with the above, "the quick-brown, fox? /jumps/ ^over^ the ¡lazy! dog..." and "C:/program files/some vendor/their 2nd application/a file1.txt".

If you want 2Nd instead of 2nd, you can change to /([a-z])(\w*)/g.

The first form can be simplified as:

function toTitleCase(toTransform) {
  return toTransform.replace(/\b([a-z])/g, function (_, initial) {
      return initial.toUpperCase();
  });
}

Simple way is generating code as bellow:

try this code to delete all data from a table..

String selectQuery = "DELETE FROM table_name ";
Cursor cursor = data1.getReadableDatabase().rawQuery(selectQuery, null);

You could use this overload of Directory.GetFiles which searches subdirectories for you, for example:

string[] files = Directory.GetFiles(sDir, "*.xml", SearchOption.AllDirectories);

Only one extension can be searched for like that, but you could use something like:

var extensions = new List<string> { ".txt", ".xml" };
string[] files = Directory.GetFiles(sDir, "*.*", SearchOption.AllDirectories)
                    .Where(f => extensions.IndexOf(Path.GetExtension(f)) >= 0).ToArray();

to select files with the required extensions (N.B. that is case-sensitive for the extension).

In some cases it can be desirable to enumerate over the files with the Directory.EnumerateFiles Method:

foreach(string f in Directory.EnumerateFiles(sDir, "*.xml", SearchOption.AllDirectories))
{
    // do something
}

Consult the documentation for exceptions which can be thrown, such as UnauthorizedAccessException if the code is running under an account which does not have appropriate access permissions.

By default it looks for the SDK tools in "C:\Documents and Settings\user\android-sdks". Some times we install it at another location. So you just have to select the correct path and it will done.

I think, the easiest way is to read readme file inside your Eclipse directory at path eclipse/readme/eclipse_readme .

At the very top of this file it clearly tells the version number:

For My Eclipse Juno; it says version as Release 4.2.0

First remove Microsoft.Web.Infrastructure from package.config.

and ran the command again

PM> Install-Package Microsoft.Web.Infrastructure and make sure Copy Local property should be true.

Blaze meter has a chrome extension for recording sessions and exporting them to JMeter (currently requires login). You also have the option of paying them money to run it on their cluster of JMeter servers (their pricing seems much better than LoadImpact which I've just stopped using):

• BlazeMeter Chrome Extension
• Blog entry about it

I don't have any association with them, I just like the look of their service, although I haven't used the paid version yet.

System.out.println(Normalizer.normalize("àèé", Normalizer.Form.NFD).replaceAll("\\p{InCombiningDiacriticalMarks}+", ""));

worked for me. The output of the snippet above gives "aee" which is what I wanted, but

System.out.println(Normalizer.normalize("àèé", Normalizer.Form.NFD).replaceAll("[^\\p{ASCII}]", ""));

didn't do any substitution.

See: http://www.postgresql.org/docs/9.1/static/arrays.html

If your non-native driver still does not allow you to pass arrays, then you can:

• pass a string representation of an array (which your stored procedure can then parse into an array -- see string_to_array)

  CREATE FUNCTION my_method(TEXT) RETURNS VOID AS $$ 
  DECLARE
         ids INT[];
  BEGIN
         ids = string_to_array($1,',');
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method(:1)
  

  with :1 = '1,2,3,4'

• rely on Postgres itself to cast from a string to an array

  CREATE FUNCTION my_method(INT[]) RETURNS VOID AS $$ 
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method('{1,2,3,4}')
  

• choose not to use bind variables and issue an explicit command string with all parameters spelled out instead (make sure to validate or escape all parameters coming from outside to avoid SQL injection attacks.)

  CREATE FUNCTION my_method(INT[]) RETURNS VOID AS $$ 
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method(ARRAY [1,2,3,4])
  

This is a native part of the webkit browsers and you cannot remove it. You should think about a hacky solution like covering or hiding the file inputs.

A hacky solution:

input[type='file'] {
  opacity:0    
}

<div>
    <input type='file'/>
    <span id='val'></span>
    <span id='button'>Select File</span>
</div>   

$('#button').click(function(){
   $("input[type='file']").trigger('click');
})

$("input[type='file']").change(function(){
   $('#val').text(this.value.replace(/C:\\fakepath\\/i, ''))
})

You could do this with the Plotly R API, with either code, or from the GUI by dragging the legend where you want it.

Here is an example. The graph and code are also here.

x = c(0,1,2,3,4,5,6,7,8) 
y = c(0,3,6,4,5,2,3,5,4) 
x2 = c(0,1,2,3,4,5,6,7,8) 
y2 = c(0,4,7,8,3,6,3,3,4)

You can position the legend outside of the graph by assigning one of the x and y values to either 100 or -100.

legendstyle = list("x"=100, "y"=1)
layoutstyle = list(legend=legendstyle)

Here are the other options:

• list("x" = 100, "y" = 0) for Outside Right Bottom
• list("x" = 100, "y"= 1) Outside Right Top
• list("x" = 100, "y" = .5) Outside Right Middle
• list("x" = 0, "y" = -100) Under Left
• list("x" = 0.5, "y" = -100) Under Center
• list("x" = 1, "y" = -100) Under Right

Then the response.

response = p$plotly(x,y,x2,y2, kwargs=list(layout=layoutstyle));

Plotly returns a URL with your graph when you make a call. You can access that more quickly by calling browseURL(response$url) so it will open your graph in your browser for you.

url = response$url
filename = response$filename

That gives us this graph. You can also move the legend from within the GUI and then the graph will scale accordingly. Full disclosure: I'm on the Plotly team.

First check if the request object have the 'is_private' key parameter. Most of the case's this MultiValueDictKeyError occurred for missing key in the dictionary-like request object. Because dictionary is an unordered key, value pair “associative memories” or “associative arrays”

In another word. request.GET or request.POST is a dictionary-like object containing all request parameters. This is specific to Django.

The method get() returns a value for the given key if key is in the dictionary. If key is not available then returns default value None.

You can handle this error by putting :

is_private = request.POST.get('is_private', False);

It means use rake that bundler is aware of and is part of your Gemfile over any rake that bundler is not aware of and run the db:migrate task.

I would use a list:

string = []
for i in range(0, 9):
  string.append("Hello")

This way, you would have 9 "Hello" and you could get them individually like this:

string[x]

Where x would identify which "Hello" you want.

So, print(string[1]) would print Hello.

According to this example Random.nextInt(n) has less predictable output then Math.random() * n. According to [sorted array faster than an unsorted array][1] I think we can say Random.nextInt(n) is hard to predict.

Here's another canvas based version with variable width (based on drawing velocity) curves: demo at http://szimek.github.io/signature_pad and code at https://github.com/szimek/signature_pad.

To support the answer by @oberstet, if the cert is not trusted by the browser (for example you get a "this site is not secure, do you want to continue?") one solution is to open the browser options, navigate to the certificates settings and add the host and post that the websocket server is being served from to the certificate provider as an exception.

for example add 'example-wss-domain.org:6001' as an exception to 'Certificate Provider Ltd'.

In firefox, this can be done from 'about:preferences' and searching for 'Certificates'

This clearly shows java pid 9862 is the culprit.

You can call a reset function before appending. Something like this:

    function resetNewReviewBoardForm() {
    $("#Description").val('');
    $("#PersonName").text('');
    $("#members").empty(); //this one what worked in my case
    $("#EmailNotification").val('False');
}

Set universal_newlines to True, i.e.

command_stdout = Popen(['ls', '-l'], stdout=PIPE, universal_newlines=True).communicate()[0]

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

class PushObjects {
    testMethod(): Array<number> { 
        //declaration and initialisation of array onject
        var objs: number[] = [1,2,3,4,5,7];
        //push the elements into the array object
        objs.push(100);
        //pop the elements from the array
        objs.pop();
        return objs;
    }   
}

let pushObj = new PushObjects();
//create the button element from the dom object 
let btn = document.createElement('button');
//set the text value of the button
btn.textContent = "Click here";
//button click event
btn.onclick = function () { 

    alert(pushObj.testMethod());

} 

document.body.appendChild(btn);

The following will do.

string datestring = DateTime.Now.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);

Bootstrap uses the variable:

$font-size-base: 1rem; // Assumes the browser default, typically 16px

I don't recommend mucking with this, but you can. Best practice is to override the browser default base font size with:

html {
  font-size: 14px;
}

Bootstrap will then take that value and use it via rems to set values for all kinds of things.

Copy & paste example for upserting one table into another, with MERGE:

CREATE GLOBAL TEMPORARY TABLE t1
    (id VARCHAR2(5) ,
     value VARCHAR2(5),
     value2 VARCHAR2(5)
     )
  ON COMMIT DELETE ROWS;

CREATE GLOBAL TEMPORARY TABLE t2
    (id VARCHAR2(5) ,
     value VARCHAR2(5),
     value2 VARCHAR2(5))
  ON COMMIT DELETE ROWS;
ALTER TABLE t2 ADD CONSTRAINT PK_LKP_MIGRATION_INFO PRIMARY KEY (id);

insert into t1 values ('a','1','1');
insert into t1 values ('b','4','5');
insert into t2 values ('b','2','2');
insert into t2 values ('c','3','3');


merge into t2
using t1
on (t1.id = t2.id) 
when matched then 
  update set t2.value = t1.value,
  t2.value2 = t1.value2
when not matched then
  insert (t2.id, t2.value, t2.value2)  
  values(t1.id, t1.value, t1.value2);

select * from t2

Result:

1. b 4 5
2. c 3 3
3. a 1 1

You could include count(id). That will always return.

select count(field1), field1 from table where id = 123 limit 1;

http://sqlfiddle.com/#!2/64c76/4

Also add the key "StartingMonthColumn" in App.config that you run application from, for example in the App.config of the test project.

Do you mean altering the table after it has been created? If so you need to use alter table, in particular:

ALTER TABLE tablename MODIFY COLUMN new-column-definition

e.g.

ALTER TABLE test MODIFY COLUMN locationExpect VARCHAR(120);

For me there was an issue in that I want to distinguish between alpha, numeric and alpha numeric, so to ensure an alphanumeric string contains at least one alpha and at least one numeric, I used :

^([a-zA-Z_]{1,}\d{1,})+|(\d{1,}[a-zA-Z_]{1,})+$

just change the following lines in CSS

.enclose {position:fixed;bottom:0px;width:100%;}

and in html:

<p class="enclose problem">

</p>

This is Chris Jester-Young's implementation, cleanest I've ever seen, combined with php.net's and a precision argument.

function formatBytes($size, $precision = 2)
{
    $base = log($size, 1024);
    $suffixes = array('', 'K', 'M', 'G', 'T');   

    return round(pow(1024, $base - floor($base)), $precision) .' '. $suffixes[floor($base)];
}

echo formatBytes(24962496);
// 23.81M

echo formatBytes(24962496, 0);
// 24M

echo formatBytes(24962496, 4);
// 23.8061M

Sounds obvious, but make sure that you are not explicitly ignoring the type:

modelBuilder.Ignore<MyType>();

I know this thread is old now, but here is some decent documentation on Google Docs API. It was ridiculously hard to find, but useful, so maybe it will help you some. http://pythonhosted.org/gdata/docs/api.html.

I used gspread recently for a project to graph employee time data. I don't know how much it might help you, but here's a link to the code: https://github.com/lightcastle/employee-timecards

Gspread made things pretty easy for me. I was also able to add logic in to check for various conditions to create month-to-date and year-to-date results. But I just imported the whole dang spreadsheet and parsed it from there, so I'm not 100% sure that it is exactly what you're looking for. Best of luck.

if you are trying to delete file using your own local host console then you can try running this python script assuming that you have have already assigned your access id and secret key in the system

import boto3

#my custom sesssion
aws_m=boto3.session.Session(profile_name="your-profile-name-on-local-host")
client=aws_m.client('s3')

#list bucket objects before deleting 
response = client.list_objects(
    Bucket='your-bucket-name'
)
for x in response.get("Contents", None):
    print(x.get("Key",None));

#delete bucket objects
response = client.delete_object(
    Bucket='your-bucket-name',
    Key='mydocs.txt'
)

#list bucket objects after deleting
response = client.list_objects(
    Bucket='your-bucket-name'
)
for x in response.get("Contents", None):
    print(x.get("Key",None));

(This method works for ifs, multiple nested loops and other constructs that you can't break from easily.)

Wrap the code in its own function. Instead of break, use return.

Example:

def some_function():
    if condition_a:
        # do something and return early
        ...
        return
    ...
    if condition_b:
        # do something else and return early
        ...
        return
    ...
    return

if outer_condition:
    ...
    some_function()
    ...

how will I know that some tables are locked?

You can use SHOW OPEN TABLES command to view locked tables.

how do I unlock tables manually?

If you know the session ID that locked tables - 'SELECT CONNECTION_ID()', then you can run KILL command to terminate session and unlock tables.

With C# 8:

int[] array = { 1, 3, 5 };
var lastItem = array[^1]; // 5

A bit late to answer, but for who is searching. You can easily do this by using an extra property with the data annotation:

public string foo { get; set; }
public string bar { get; set; }

[MinLength(20, ErrorMessage = "too short")]
public string foobar 
{ 
    get
    {
        return foo + bar;
    }
}

That's all that is too it really. If you really want to display in a specific place the validation error as well, you can add this in your view:

@Html.ValidationMessage("foobar", "your combined text is too short")

doing this in the view can come in handy if you want to do localization.

Hope this helps!

A grammar is context-free if all production rules have the form: A (that is, the left side of a rule can only be a single variable; the right side is unrestricted and can be any sequence of terminals and variables). We can define a grammar as a 4-tuple where V is a finite set (variables), _ is a finite set (terminals), S is the start variable, and R is a finite set of rules, each of which is a mapping V
regular grammar is either right or left linear, whereas context free grammar is basically any combination of terminals and non-terminals. hence we can say that regular grammar is a subset of context-free grammar. After these properties we can say that Context Free Languages set also contains Regular Languages set

You cannot delete the records that way, the main issue being that you cannot use a subquery to specify the value of a LIMIT clause.

This works (tested in MySQL 5.0.67):

DELETE FROM `table`
WHERE id NOT IN (
  SELECT id
  FROM (
    SELECT id
    FROM `table`
    ORDER BY id DESC
    LIMIT 42 -- keep this many records
  ) foo
);

The intermediate subquery is required. Without it we'd run into two errors:

1. SQL Error (1093): You can't specify target table 'table' for update in FROM clause - MySQL doesn't allow you to refer to the table you are deleting from within a direct subquery.
2. SQL Error (1235): This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery' - You can't use the LIMIT clause within a direct subquery of a NOT IN operator.

Fortunately, using an intermediate subquery allows us to bypass both of these limitations.

Nicole has pointed out this query can be optimised significantly for certain use cases (such as this one). I recommend reading that answer as well to see if it fits yours.

First, convert the timestamp using the built-in eloquent functionality, as described in this answer.

Then you can just use Carbon's min() or max() function for comparison. For example:

$dt1 = Carbon::create(2012, 1, 1, 0, 0, 0); $dt2 = Carbon::create(2014, 1, 30, 0, 0, 0); echo $dt1->min($dt2);

This will echo the lesser of the two dates, which in this case is $dt1.

See http://carbon.nesbot.com/docs/

Yet, another really simple solution is this one:

html, body {
    height: 100%;
    width: 100%;
    margin: 0;
    display: table;
}

footer {
    background-color: grey;
    display: table-row;
    height: 0;
}

jsFiddle

The trick is to use a display:table for the whole document and display:table-row with height:0 for the footer.

Since the footer is the only body child that has a display as table-row, it is rendered at the bottom of the page.

I got the answer, I was using:

em.persist(user);

I used merge in place of persist:

em.merge(user);

But no idea, why persist didn't work. :(

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

The Code is very Simple, Lets Put This Code

var name = $("#band_type_choices  option:selected").text();

Here You don't want to use $(this).find().text(), directly you can put your id name and add option:selected along with text().

This will return the result option name. Better Try this...

The following code will allow you to have two headings on the same line, the first left-aligned and the second right-aligned, and has the added advantage of keeping both headings on the same baseline.

The HTML Part:

<h1 class="text-left-right">
    <span class="left-text">Heading Goes Here</span>
    <span class="byline">Byline here</span>
</h1>

And the CSS:

.text-left-right {
    text-align: right;
    position: relative;
}
.left-text {
    left: 0;
    position: absolute;
}
.byline {
    font-size: 16px;
    color: rgba(140, 140, 140, 1);
}

Permissions error

Some very noob users like me face this problem when having incorrect permissions set in a page (in particular, that "other" users do not have read permissions). For example, say you are attempting to access index.html, and you get the above error. To fix, type:

chmod o+r index.html

and then upload to server again. Error disappears.

You simply can't.

bcrypt uses salting, of different rounds, I use 10 usually.

bcrypt.hash(req.body.password,10,function(error,response){ }

This 10 is salting random string into your password.

Try setting the file path using (for anaconda3)...

export PATH=~/anaconda3/bin:$PATH

Then check whether it worked with...

conda --version

This worked for me when 'conda' was returning 'command not found'.

To my knowledge the use of the keyword new, does relatively the same thing as malloc(sizeof identifier). The code below demonstrates how to use the keyword new.

    void main(void){
        int* test;
        test = tester();
        printf("%d",*test);
        system("pause");
    return;
}
    int* tester(void){
        int *retMe;
        retMe = new int;//<----Here retMe is getting malloc for integer type
        *retMe = 12;<---- Initializes retMe... Note * dereferences retMe 
    return retMe;
}

I think there is a semantic problem here. In my view, a user can have a (but only one) favourite recipe to prepare a specific menu. (The OP has menu and recipe mixed up; if I am wrong: please interchange MenuId and RecipeId below) That implies that {user,menu} should be a unique key in this table. And it should point to exactly one recipe. If the user has no favourite recipe for this specific menu no row should exist for this {user,menu} key pair. Also: the surrogate key (FaVouRiteId) is superfluous: composite primary keys are perfectly valid for relational-mapping tables.

That would lead to the reduced table definition:

CREATE TABLE Favorites
( UserId uuid NOT NULL REFERENCES users(id)
, MenuId uuid NOT NULL REFERENCES menus(id)
, RecipeId uuid NOT NULL REFERENCES recipes(id)
, PRIMARY KEY (UserId, MenuId)
);

Similar to what binnyb suggested, you might consider using the newer Calendar > GregorianCalendar method. See these more recent docs:

http://download.oracle.com/javase/6/docs/api/java/util/GregorianCalendar.html

Javascript always passes by value. However, if you pass an object to a function, the "value" is really a reference to that object, so the function can modify that object's properties but not cause the variable outside the function to point to some other object.

An example:

function changeParam(x, y, z) {
  x = 3;
  y = "new string";
  z["key2"] = "new";
  z["key3"] = "newer";

  z = {"new" : "object"};
}

var a = 1,
    b = "something",
    c = {"key1" : "whatever", "key2" : "original value"};

changeParam(a, b, c);

// at this point a is still 1
// b is still "something"
// c still points to the same object but its properties have been updated
// so it is now {"key1" : "whatever", "key2" : "new", "key3" : "newer"}
// c definitely doesn't point to the new object created as the last line
// of the function with z = ...

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

try this

.hiddencol
    {
        display:none;
    }
    .viscol
    {
        display:block;
    }

add following code on RowCreated Event of GridView

protected void OnRowCreated(object sender, GridViewRowEventArgs e)
{
     if (e.Row.RowType == DataControlRowType.DataRow)
     {
         e.Row.Cells[0].CssClass = "hiddencol";
     }
     else if (e.Row.RowType == DataControlRowType.Header)
     {
         e.Row.Cells[0].CssClass = "hiddencol";
     }
}

I changed my deployment target to 7.1 the same as my iphone, and now I can run swift programs on it. It was on 8.0 and showed up as ineligible.

for /r %%v in (*.xls) do ssconvert "%%v" "%%vx"

a couple have people have asked me to explain this, so:

Part 1: for /r %%v in (*.xls)

This part returns an array of files in the current directory that have the xls extension. The %% may look a little curious. This is basically the special % character from command line as used in %PATH% or %TEMP%. To use it in a batch file we need to escape it like so: %%PATH%% or %%TEMP%%. In this case we are simply escaping the temporary variable v, which will hold our array of filenames.

We are using the /r switch to search for files recursively, so any matching files in child folders will also be located.

Part 2: do ssconvert "%%v" "%%vx"

This second part is what will get executed once per matching filename, so if the following files were present in the current folder:

c:\temp\mySheet.xls, c:\temp\mySheet_yesterday.xls, c:\temp\mySheet_20160902.xls

the following commands would be executed:

ssconvert "c:\temp\mySheet.xls" "c:\temp\mySheet.xlsx" ssconvert "c:\temp\mySheet_yesterday.xls" "c:\temp\mySheet_yesterday.xlsx" ssconvert "c:\temp\mySheet_20160902.xls" "c:\temp\mySheet_20160902.xlsx"

The top answer works in the case that you want to examine the state immediately prior to the failed command.

However, the question asks how to examine the state of the failed container itself. In my situation, the failed command is a build that takes several hours, so rewinding prior to the failed command and running it again takes a long time and is not very helpful.

The solution here is to find the container that failed:

$ docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                          PORTS               NAMES
6934ada98de6        42e0228751b3        "/bin/sh -c './utils/"   24 minutes ago      Exited (1) About a minute ago                       sleepy_bell

Commit it to an image:

$ docker commit 6934ada98de6
sha256:7015687976a478e0e94b60fa496d319cdf4ec847bcd612aecf869a72336e6b83

And then run the image [if necessary, running bash]:

$ docker run -it 7015687976a4 [bash -il]

Now you are actually looking at the state of the build at the time that it failed, instead of at the time before running the command that caused the failure.

Another solution that does not involve converting to/from strings:

from math import log10

def decompose(n):
    if n == 0:
        return [0]
    b = int(log10(n)) + 1
    return [(n // (10 ** i)) % 10 for i in reversed(range(b))]

Looks to be more efficient to add the recognizer directly to the cell as shown here:

Tap&Hold for TableView Cells, Then and Now

(scroll to the example at the bottom)

Others have answered your question, but I'll go into a little bit more detail:

Python's is compares identity - it asks the question "is this one thing actually the same object as this other thing" (similar to == in Java). So, there are some times when using is makes sense - the most common one being checking for None. Eg, foo is None. But, in general, it isn't what you want.

==, on the other hand, asks the question "is this one thing logically equivalent to this other thing". For example:

>>> [1, 2, 3] == [1, 2, 3]
True
>>> [1, 2, 3] is [1, 2, 3]
False

And this is true because classes can define the method they use to test for equality:

>>> class AlwaysEqual(object):
...     def __eq__(self, other):
...         return True
...
>>> always_equal = AlwaysEqual()
>>> always_equal == 42
True
>>> always_equal == None
True

But they cannot define the method used for testing identity (ie, they can't override is).

if you're already logged in as root just

mysql -u root

prompting the password will otherwise return as error

There's always cmd. It may be less annoying if you have trouble quoting arguments to start-process:

cmd /c start /wait notepad

Or

notepad | out-host

FPM is a process manager to manage the FastCGI SAPI (Server API) in PHP.

Basically, it replaces the need for something like SpawnFCGI. It spawns the FastCGI children adaptively (meaning launching more if the current load requires it).

Otherwise, there's not much operating difference between it and FastCGI (The request pipeline from start of request to end is the same). It's just there to make implementing it easier.

Recently I want to install squirrel.windows, I tried Install-Package squirrel.windows -Version 2.0.1 from https://www.nuget.org/packages/squirrel.windows/, but it failed with some errors. So I downloaded squirrel.windows.2.0.1.nupkg and save it in D:\Downloads\, then I can install it success via Install-Package squirrel.windows -verbose -Source D:\Downloads\ -Scope CurrentUser -SkipDependencies in powershell.

• First you should run this sudo apt-get build-dep python-imaging which will give you all the dependencies that you might need

• Then run sudo apt-get update && sudo apt-get -y upgrade

• Followed by sudo apt-get install python-pip

• And then finally install Pil pip install pillow

If you have a string of binary data which is Base64 encoded, you should be able to do the following:

byte[] encodedDataAsBytes = System.Convert.FromBase64String(encodedData);

You should be able to write the resulting array to a file.

@Baxter's is mostly correct but it is missing one important Windows-specific detail.

Subversion's runtime configuration area is stored in the %APPDATA%\Subversion\ directory. The files are config and servers.

However, in addition to text-based configuration files, Subversion clients can use Windows Registry to store the client settings. It makes it possible to modify the settings with PowerShell in a convenient manner, and also distribute these settings to user workstations in Active Directory environment via AD Group Policy. See SVNBook | Configuration and the Windows Registry (you can find examples and a sample *.reg file there).

It seems that you are trying to get 5 items out of a collection with 5 items. Looking at your code, it seems you're starting at the second value in your collection at position 1. Collections are zero-based, so you should start with the item at index 0. Try this:

TextBox box1 = (TextBox)Gridview1.Rows[i].Cells[0].FindControl("txt_type");
TextBox box2 = (TextBox)Gridview1.Rows[i].Cells[1].FindControl("txt_total");
TextBox box3 = (TextBox)Gridview1.Rows[i].Cells[2].FindControl("txt_max");
TextBox box4 = (TextBox)Gridview1.Rows[i].Cells[3].FindControl("txt_min");
TextBox box5 = (TextBox)Gridview1.Rows[i].Cells[4].FindControl("txt_rate");

You can find a comprehensive set of solutions on this in UNIX & Linux's answer to How do you move all files (including hidden) from one directory to another?. It shows solutions in Bash, zsh, ksh93, standard (POSIX) sh, etc.

You can use these two commands together:

mv /path/subfolder/* /path/   # your current approach
mv /path/subfolder/.* /path/  # this one for hidden files

Or all together (thanks pfnuesel):

mv /path/subfolder/{.,}* /path/

Which expands to:

mv /path/subfolder/* /path/subfolder/.* /path/

(example: echo a{.,}b expands to a.b ab)

Note this will show a couple of warnings:

mv: cannot move ‘/path/subfolder/.’ to /path/.’: Device or resource busy
mv: cannot remove /path/subfolder/..’: Is a directory

Just ignore them: this happens because /path/subfolder/{.,}* also expands to /path/subfolder/. and /path/subfolder/.., which are the directory and the parent directory (See What do “.” and “..” mean when in a folder?).

If you want to just copy, you can use a mere:

cp -r /path/subfolder/. /path/
#                     ^
#                     note the dot!

This will copy all files, both normal and hidden ones, since /path/subfolder/. expands to "everything from this directory" (Source: How to copy with cp to include hidden files and hidden directories and their contents?)

Yes, you can get it from the File object by using File.toPath(). Keep in mind that this is only for Java 7+. Java versions 6 and below do not have it.

Are you using the userdir mod?

In that case the thing is that PHP5 seems to be disabling running scripts from that location by default and you have to comment out the following lines:

<IfModule mod_userdir.c>
    <Directory /home/*/public_html>
        php_admin_flag engine Off
    </Directory>
</IfModule>

in /etc/apache2/mods-enabled/php5.conf (on a ubuntu system)

Numpy is required by pandas (and by virtually all numerical tools for Python). Scipy is not strictly required for pandas but is listed as an "optional dependency". I wouldn't say that pandas is an alternative to Numpy and/or Scipy. Rather, it's an extra tool that provides a more streamlined way of working with numerical and tabular data in Python. You can use pandas data structures but freely draw on Numpy and Scipy functions to manipulate them.

This fixed issues for me:

<style>
.super-centered {
    position:absolute; 
    width:100%;
    height:100%;
    text-align:center; 
    vertical-align:middle;
    z-index: 9999;
}
</style>

<table class="super-centered"><tr><td style="width:100%;height:100%;" align="center"     valign="middle" > 
<img alt="Loading ..." src="/ALHTheme/themes/html/ALHTheme/images/loading.gif">

Based on what type of RFC standard encoding you want to perform or if you need to customize your encoding you might want to create your own class.

/**
 * UrlEncoder make it easy to encode your URL
 */
class UrlEncoder{
    public const STANDARD_RFC1738 = 1;
    public const STANDARD_RFC3986 = 2;
    public const STANDARD_CUSTOM_RFC3986_ISH = 3;
    // add more here

    static function encode($string, $rfc){
        switch ($rfc) {
            case self::STANDARD_RFC1738:
                return  urlencode($string);
                break;
            case self::STANDARD_RFC3986:
                return rawurlencode($string);
                break;
            case self::STANDARD_CUSTOM_RFC3986_ISH:
                // Add your custom encoding
                $entities = ['%21', '%2A', '%27', '%28', '%29', '%3B', '%3A', '%40', '%26', '%3D', '%2B', '%24', '%2C', '%2F', '%3F', '%25', '%23', '%5B', '%5D'];
                $replacements = ['!', '*', "'", "(", ")", ";", ":", "@", "&", "=", "+", "$", ",", "/", "?", "%", "#", "[", "]"];
                return str_replace($entities, $replacements, urlencode($string));
                break;
            default:
                throw new Exception("Invalid RFC encoder - See class const for reference");
                break;
        }
    }
}

Use example:

$dataString = "https://www.google.pl/search?q=PHP is **great**!&id=123&css=#kolo&[email protected])";

$dataStringUrlEncodedRFC1738 = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_RFC1738);
$dataStringUrlEncodedRFC3986 = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_RFC3986);
$dataStringUrlEncodedCutom = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_CUSTOM_RFC3986_ISH);

Will output:

string(126) "https%3A%2F%2Fwww.google.pl%2Fsearch%3Fq%3DPHP+is+%2A%2Agreat%2A%2A%21%26id%3D123%26css%3D%23kolo%26email%3Dme%40liszka.com%29"

From this post: How to deal with floating point number precision in JavaScript?

You have a few options:

• Use a special datatype for decimals, like decimal.js
• Format your result to some fixed number of significant digits, like this: (Math.floor(y/x) * x).toFixed(2)
• Convert all your numbers to integers

You can try using .net:

$Reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $computer1)
$RegKey= $Reg.OpenSubKey("SOFTWARE\\Veritas\\NetBackup\\CurrentVersion")
$NetbackupVersion1 = $RegKey.GetValue("PackageVersion")

Based on my comment to the accepted answer, there are a lot potential pitfalls that you may encounter by declaring font-sizes smaller than 12px. By declaring styles that lead to computed font-sizes of less than 12px, like so:

html {
  font-size: 8px;
}
p {
  font-size: 1.4rem;
}
// Computed p size: 11px.

You'll run into issues with browsers, like Chrome with a Chinese language pack that automatically renders any font sizes computed under 12px as 12px. So, the following is true:

h6 {
    font-size: 12px;
}
p {
   font-size: 8px;
}
// Both render at 12px in Chrome with a Chinese language pack.   
// How unpleasant of a surprise.

I would also argue that for accessibility reasons, you generally shouldn't use sizes under 12px. You might be able to make a case for captions and the like, but again--prepare to be surprised under some browser setups, and prepared to make your grandma squint when she's trying to read your content.

I would instead, opt for something like this:

h1 {
    font-size: 2.5rem;
}

h2 {
    font-size: 2.25rem;
}

h3 {
    font-size: 2rem;
}

h4 {
    font-size: 1.75rem;
}

h5 {
    font-size: 1.5rem;
}

h6 {
    font-size: 1.25rem;
}

p {
    font-size: 1rem;
}

@media (max-width: 480px) {
    html {
        font-size: 12px;
    }
}

@media (min-width: 480px) {
    html {
        font-size: 13px;
    }
}

@media (min-width: 768px) {
    html {
        font-size: 14px;
    }
}

@media (min-width: 992px) {
    html {
        font-size: 15px;
    }
}

@media (min-width: 1200px) {
    html {
        font-size: 16px;
    }
}

You'll find that tons of sites that have to focus on accessibility use rather large font sizes, even for p elements.

As a side note, setting margin-bottom equal to the font-size usually also tends to be attractive, i.e.:

h1 {
    font-size: 2.5rem;
    margin-bottom: 2.5rem;
}

Good luck.

You need to do some escaping I think.

find /home/me/download/ -type f -name "*.rm" -exec ffmpeg -i {} \-sameq {}.mp3 \&\& rm {}\;

.NET Example as requested:

using (client)
{
    var existingObject = client.ListObjects(requestForExisingFile).S3Objects; 
    if (existingObject.Count == 1)
    {
        var requestCopyObject = new CopyObjectRequest()
        {
            SourceBucket = BucketNameProd,
            SourceKey = objectToMerge.Key,
            DestinationBucket = BucketNameDev,
            DestinationKey = newKey
        };
        client.CopyObject(requestCopyObject);
    }
}

with client being something like

var config = new AmazonS3Config { CommunicationProtocol = Protocol.HTTP, ServiceURL = "s3-eu-west-1.amazonaws.com" };
var client = AWSClientFactory.CreateAmazonS3Client(AWSAccessKey, AWSSecretAccessKey, config);

There might be a better way, but it's just some quick code I wrote to get some files transferred.

My Thought,

Implicit Wait : If wait is set, it will wait for specified amount of time for each findElement/findElements call. It will throw an exception if action is not complete.

Explicit Wait : If wait is set, it will wait and move on to next step when the provided condition becomes true else it will throw an exception after waiting for specified time. Explicit wait is applicable only once wherever specified.

You can do it with PhantomJSDriver.

PhantomJSDriver pd = ((PhantomJSDriver) ((WebDriverFacade) getDriver()).getProxiedDriver());
pd.executePhantomJS(
            "this.onResourceRequested = function(request, net) {" +
            "   net.setHeader('header-name', 'header-value')" +
            "};");

Using the request object, you can filter also so the header won't be set for every request.

Instead of checking codes, this works too

net start "Apache tomcat" || goto ExitError

:End  
exit 0  

:ExitError  
echo An error has occurred while starting the tomcat services  
exit 1  

If you cannot utilize the ActiveDirectory Module or the Get-ADGroupMember cmdlet, you can do it with the LDAP "in chain"-matching rule:

$GroupDN = "CN=MyGroup,OU=Groups,DC=mydomain,DC=tld"
$LDAPFilter = "(&(objectClass=user)(objectCategory=Person)(memberOf:1.2.840.113556.1.4.1941:=$GroupDN))"

# Ideally using an instance of adsisearcher here:
Get-ADObject -LDAPFilter $LDAPFilter

See MSDN for additional LDAP matching rules implemented in Active Directory

May be useful for some:

(a function that allow you to add the data to the form using an object, with override for existing inputs, if there is) [pure js]

(form is a dom el, and not a jquery object [jqryobj.get(0) if you need])

function addDataToForm(form, data) {
    if(typeof form === 'string') {
        if(form[0] === '#') form = form.slice(1);
        form = document.getElementById(form);
    }

    var keys = Object.keys(data);
    var name;
    var value;
    var input;

    for (var i = 0; i < keys.length; i++) {
        name = keys[i];
        // removing the inputs with the name if already exists [overide]
        // console.log(form);
        Array.prototype.forEach.call(form.elements, function (inpt) {
             if(inpt.name === name) {
                 inpt.parentNode.removeChild(inpt);
             }
        });

        value = data[name];
        input = document.createElement('input');
        input.setAttribute('name', name);
        input.setAttribute('value', value);
        input.setAttribute('type', 'hidden');

        form.appendChild(input);
    }

    return form;
}

Use :

addDataToForm(form, {
    'uri': window.location.href,
     'kpi_val': 150,
     //...
});

you can use it like that too

var form = addDataToForm('myFormId', {
    'uri': window.location.href,
     'kpi_val': 150,
     //...
});

you can add # if you like too ("#myformid").

If you want the JSON of a good quality profile picture with the URL you can use that:

http://graph.facebook.com/517267866/picture?height=1024&redirect=false

if you just need the picture use it without the parameter redirect:

http://graph.facebook.com/517267866/picture?height=1024

517267866 is the profile ID of one of the above examples. Put the facebook id that you need

I hope that helps

They are not really same mutexes, lock_guard<muType> has nearly the same as std::mutex, with a difference that it's lifetime ends at the end of the scope (D-tor called) so a clear definition about these two mutexes :

lock_guard<muType> has a mechanism for owning a mutex for the duration of a scoped block.

And

unique_lock<muType> is a wrapper allowing deferred locking, time-constrained attempts at locking, recursive locking, transfer of lock ownership, and use with condition variables.

Here is an example implemetation :

#include <iostream>
#include <thread>
#include <mutex>
#include <condition_variable>
#include <functional>
#include <chrono>

using namespace std::chrono;

class Product{

   public:

       Product(int data):mdata(data){
       }

       virtual~Product(){
       }

       bool isReady(){
       return flag;
       }

       void showData(){

        std::cout<<mdata<<std::endl;
       }

       void read(){

         std::this_thread::sleep_for(milliseconds(2000));

         std::lock_guard<std::mutex> guard(mmutex);

         flag = true;

         std::cout<<"Data is ready"<<std::endl;

         cvar.notify_one();

       }

       void task(){

       std::unique_lock<std::mutex> lock(mmutex);

       cvar.wait(lock, [&, this]() mutable throw() -> bool{ return this->isReady(); });

       mdata+=1;

       }

   protected:

    std::condition_variable cvar;
    std::mutex mmutex;
    int mdata;
    bool flag = false;

};

int main(){

     int a = 0;
     Product product(a);

     std::thread reading(product.read, &product);
     std::thread setting(product.task, &product);

     reading.join();
     setting.join();


     product.showData();
    return 0;
}

In this example, i used the unique_lock<muType> with condition variable

I would also recommend the sitepen guides

https://www.sitepen.com/blog/2013/12/31/definitive-guide-to-typescript/ (see below) and https://www.sitepen.com/blog/2014/08/22/advanced-typescript-concepts-classes-types/

TypeScript also allows you to specify different return types when an exact string is provided as an argument to a function. For example, TypeScript’s ambient declaration for the DOM’s createElement method looks like this:

createElement(tagName: 'a'): HTMLAnchorElement;
createElement(tagName: 'abbr'): HTMLElement;
createElement(tagName: 'address'): HTMLElement;
createElement(tagName: 'area'): HTMLAreaElement;
// ... etc.
createElement(tagName: string): HTMLElement;

This means, in TypeScript, when you call e.g. document.createElement('video'), TypeScript knows the return value is an HTMLVideoElement and will be able to ensure you are interacting correctly with the DOM Video API without any need to type assert.

Here is my bash script

docker build -t ${IMAGE}:${VERSION} .
docker tag ${IMAGE}:${VERSION} ${IMAGE}:latest

You can then remove untagged images if you rebuilt the same version with

docker rmi $(docker images | grep "^<none>" | awk "{print $3}")

link

or

docker rmi $(docker images | grep "^<none>" | tr -s " " | cut -d' ' -f3 | tr '\n' ' ')

or

Clean up commands:

Docker 1.13 introduces clean-up commands. To remove all unused containers, images, networks and volumes:

docker system prune

or individually:

docker container prune
docker image prune
docker network prune
docker volume prune

I added return of object where attributes are parsed out style/values:

var getClassStyle = function(className){
    var x, sheets,classes;
    for( sheets=document.styleSheets.length-1; sheets>=0; sheets-- ){
        classes = document.styleSheets[sheets].rules || document.styleSheets[sheets].cssRules;
        for(x=0;x<classes.length;x++) {
            if(classes[x].selectorText===className){
                classStyleTxt = (classes[x].cssText ? classes[x].cssText : classes[x].style.cssText).match(/\{\s*([^{}]+)\s*\}/)[1];
                var classStyles = {};
                var styleSets = classStyleTxt.match(/([^;:]+:\s*[^;:]+\s*)/g);
                for(y=0;y<styleSets.length;y++){
                    var style = styleSets[y].match(/\s*([^:;]+):\s*([^;:]+)/);
                    if(style.length > 2)
                        classStyles[style[1]]=style[2];
                }
                return classStyles;
            }
        }
    }
    return false;
};

db.data.update({'name': 'zero'}, {'$set': {'value': NumberInt(0)}})

You can also use NumberLong.

Here is a sample XAML that will allow TextBox to accept multiline text and it uses its own scrollbars:

<TextBox
Height="200"
Width="500"
TextWrapping="Wrap"
AcceptsReturn="True"
HorizontalScrollBarVisibility="Disabled"
VerticalScrollBarVisibility="Auto"/>

If, like me, you find you want essentially the same sorting code in more than one place, or just want to keep the code complexity down, you can abstract away the sorting itself to a separate function, to which you pass the function that does the actual work you want (which would be different at each call site, of course).

Given a map with key type K and value type V, represented as <K> and <V> below, the common sort function might look something like this Go-code template (which Go version 1 does not support as-is):

/* Go apparently doesn't support/allow 'interface{}' as the value (or
/* key) of a map such that any arbitrary type can be substituted at
/* run time, so several of these nearly-identical functions might be
/* needed for different key/value type combinations. */
func sortedMap<K><T>(m map[<K>]<V>, f func(k <K>, v <V>)) {
    var keys []<K>
    for k, _ := range m {
        keys = append(keys, k)
    }
    sort.Strings(keys)  # or sort.Ints(keys), sort.Sort(...), etc., per <K>
    for _, k := range keys {
        v := m[k]
        f(k, v)
    }
}

Then call it with the input map and a function (taking (k <K>, v <V>) as its input arguments) that is called over the map elements in sorted-key order.

So, a version of the code in the answer posted by Mingu might look like:

package main

import (
    "fmt"
    "sort"
)

func sortedMapIntString(m map[int]string, f func(k int, v string)) {
    var keys []int
    for k, _ := range m {
        keys = append(keys, k)
    }
    sort.Ints(keys)
    for _, k := range keys {
        f(k, m[k])
    }
}

func main() {
    // Create a map for processing
    m := make(map[int]string)
    m[1] = "a"
    m[2] = "c"
    m[0] = "b"

    sortedMapIntString(m,
        func(k int, v string) { fmt.Println("Key:", k, "Value:", v) })
}

The sortedMapIntString() function can be re-used for any map[int]string (assuming the same sort order is desired), keeping each use to just two lines of code.

Downsides include:

• It's harder to read for people unaccustomed to using functions as first-class
• It might be slower (I haven't done performance comparisons)

Other languages have various solutions:

• If the use of <K> and <V> (to denote types for the key and value) looks a bit familiar, that code template is not terribly unlike C++ templates.
• Clojure and other languages support sorted maps as fundamental data types.
• While I don't know of any way Go makes range a first-class type such that it could be substituted with a custom ordered-range (in place of range in the original code), I think some other languages provide iterators that are powerful enough to accomplish the same thing.

Use this one:

Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")

Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")

With rng.Validation
    .Delete 'delete previous validation
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
        Formula1:="='" & ws.Name & "'!" & range1.Address
End With

Note that when you're using Dim range1, rng As range, only rng has type of Range, but range1 is Variant. That's why I'm using Dim range1 As Range, rng As Range.
About meaning of parameters you can read is MSDN, but in short:

• Type:=xlValidateList means validation type, in that case you should select value from list
• AlertStyle:=xlValidAlertStop specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.
• in your original code, Operator:= xlBetween is odd. It can be used only if two formulas are provided for validation.
• Formula1:="='" & ws.Name & "'!" & range1.Address for list data validation provides address of list with values (in format =Sheet!A1:A5)

Using dotPeek helps to see how the framework actually does it. With that in mind, here's what I've come up with:

public static class EnvironmentHelper
{
    [DllImport("kernel32.dll")]
    static extern IntPtr GetCurrentProcess();

    [DllImport("kernel32.dll")]
    static extern IntPtr GetModuleHandle(string moduleName);

    [DllImport("kernel32")]
    static extern IntPtr GetProcAddress(IntPtr hModule, string procName);

    [DllImport("kernel32.dll")]
    static extern bool IsWow64Process(IntPtr hProcess, out bool wow64Process);

    public static bool Is64BitOperatingSystem()
    {
        // Check if this process is natively an x64 process. If it is, it will only run on x64 environments, thus, the environment must be x64.
        if (IntPtr.Size == 8)
            return true;
        // Check if this process is an x86 process running on an x64 environment.
        IntPtr moduleHandle = GetModuleHandle("kernel32");
        if (moduleHandle != IntPtr.Zero)
        {
            IntPtr processAddress = GetProcAddress(moduleHandle, "IsWow64Process");
            if (processAddress != IntPtr.Zero)
            {
                bool result;
                if (IsWow64Process(GetCurrentProcess(), out result) && result)
                    return true;
            }
        }
        // The environment must be an x86 environment.
        return false;
    }
}

Example usage:

EnvironmentHelper.Is64BitOperatingSystem();

SELECT *
FROM LogRequests
WHERE cast(dateX as date) between '2014-05-09' and '2014-05-10';

This will select all the data between the 2 dates

Here's a suggestion: use two indices into the string, say start and end. start points to the first character of the next string to extract, end points to the character after the last one belonging to the next string to extract. start starts at zero, end gets the position of the first char after start. Then you take the string between [start..end) and add that to your array. You keep going until you hit the end of the string.

Update based on latest Android documentation (March 2017):

When you get this type of error:

javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
        at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:374)

        at libcore.net.http.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:271)

the issue could be one of the following:

1. The CA that issued the server certificate was unknown
2. The server certificate wasn't signed by a CA, but was self signed
3. The server configuration is missing an intermediate CA

The solution is to teach HttpsURLConnection to trust a specific set of CAs. How? Please check https://developer.android.com/training/articles/security-ssl.html#CommonProblems

Others who are using AsyncHTTPClient from com.loopj.android:android-async-http library, please check Setup AsyncHttpClient to use HTTPS.

Use map function

var values = $("input[name^='card']").map(function (idx, ele) {
   return $(ele).val();
}).get();

Like what Volker mentioned, nested structs is the way to go. But if you really do not want nested structs, you can override the UnmarshalJSON func.

https://play.golang.org/p/dqn5UdqFfJt

type A struct {
    FooBar string // takes foo.bar
    FooBaz string // takes foo.baz
    More   string 
}

func (a *A) UnmarshalJSON(b []byte) error {

    var f interface{}
    json.Unmarshal(b, &f)

    m := f.(map[string]interface{})

    foomap := m["foo"]
    v := foomap.(map[string]interface{})

    a.FooBar = v["bar"].(string)
    a.FooBaz = v["baz"].(string)
    a.More = m["more"].(string)

    return nil
}

Please ignore the fact that I'm not returning a proper error. I left that out for simplicity.

UPDATE: Correctly retrieving "more" value.

#include<stdio.h>
int main()
{
 int i,j,n,b;
 printf("Enter no of rows ");
 scanf("%d",&n);
 b=n;
 for(i=1;i<=n;++i)
 {
    for(j=1;j<=i;j++)
    {
        printf("%*d",b,j);
        b=1;
    }
        b=n;
    b=b-i;
    printf("\n");


 }
 return 0;
}

Annotating with @JsonAlias which got introduced with Jackson 2.9+, without mentioning @JsonProperty on the item to be deserialized with more than one alias(different names for a json property) works fine.

I used com.fasterxml.jackson.annotation.JsonAlias for package consistency with com.fasterxml.jackson.databind.ObjectMapper for my use-case.

For e.g.:

@Data
@Builder
public class Chair {

    @JsonAlias({"woodenChair", "steelChair"})
    private String entityType;

}


@Test
public void test1() {

   String str1 = "{\"woodenChair\":\"chair made of wood\"}";
   System.out.println( mapper.readValue(str1, Chair.class));
   String str2 = "{\"steelChair\":\"chair made of steel\"}";
   System.out.println( mapper.readValue(str2, Chair.class));

}

just works fine.

You can try onload event as well;

var createIframe = function (src) {
        var self = this;
        $('<iframe>', {
            src: src,
            id: 'iframeId',
            frameborder: 1,
            scrolling: 'no',
            onload: function () {
                self.isIframeLoaded = true;
                console.log('loaded!');
            }
        }).appendTo('#iframeContainer');

    };

Using extends you can only get from the collection. You cannot put into it. Also, though super allows to both get and put, the return type during get is ? super T.

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

You can use like this

${fn:length(numList)}

Yes, there is a way to do this. You could use a pseudo-element after to position a block on top of your background image. Something like this: http://jsfiddle.net/Pevara/N2U6B/

The css for the :after looks like this:

#the-div:hover:after {
    content: ' ';
    position: absolute;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    background-color: rgba(0,0,0,.5);
}

edit:
When you want to apply this to a non-empty element, and just get the overlay on the background, you can do so by applying a positive z-index to the element, and a negative one to the :after. Something like this:

#the-div {
    ...
    z-index: 1;
}
#the-div:hover:after {
    ...
    z-index: -1;
}

And the updated fiddle: http://jsfiddle.net/N2U6B/255/

An updated answer, for 4.6.0+, if you have a preference for promises (see docs):

mongoose.connect('mongodb://localhost/mydb', { useMongoClient: true })
.then((connection) => {
   connection.db.dropDatabase();
   // alternatively:
   // mongoose.connection.db.dropDatabase();
});

I tested this code in my own code, using mongoose 4.13.6. Also, note the use of the useMongoClient option (see docs). Docs indicate:

Mongoose's default connection logic is deprecated as of 4.11.0. Please opt in to the new connection logic using the useMongoClient option, but make sure you test your connections first if you're upgrading an existing codebase!

This solution is working with Android Studio 4.0.1.

Apart from creating a new module as suggested in above solution, you can try this solution.

If you have multiple modules in your application and want to add aar to just one of the module then this solution come handy.

In your root project build.gradle

add

repositories {
mavenCentral()
flatDir {
    dirs 'libs'
}

Then in the module where you want to add the .aar file locally. simply add below lines of code.

dependencies {
api fileTree(include: ['*.aar'], dir: 'libs')
implementation files('libs/<yourAarName>.aar')

}

Happy Coding :)

You may use the following function to send a status change:

            509 => 'Bandwidth Limit Exceeded',
            510 => 'Not Extended'
        );
    }

    if ($status_codes[$statusCode] !== null) {
        $status_string = $statusCode . ' ' . $status_codes[$statusCode];
        header($_SERVER['SERVER_PROTOCOL'] . ' ' . $status_string, true, $statusCode);
    }
}

You may use it as such:

<?php
header_status(500);

if (that_happened) {
    die("that happened")
}

if (something_else_happened) {
    die("something else happened")
}

update_database();

header_status(200);

Just write a following code on top of PHP file:

ini_set('display_errors','on');

Virtual memory is, among other things, an abstraction to give the programmer the illusion of having infinite memory available on their system.

Virtual memory mappings are made to correspond to actual physical addresses. The operating system creates and deals with these mappings - utilizing the page table, among other data structures to maintain the mappings. Virtual memory mappings are always found in the page table or some similar data structure (in case of other implementations of virtual memory, we maybe shouldn't call it the "page table"). The page table is in physical memory as well - often in kernel-reserved spaces that user programs cannot write over.

Virtual memory is typically larger than physical memory - there wouldn't be much reason for virtual memory mappings if virtual memory and physical memory were the same size.

Only the needed part of a program is resident in memory, typically - this is a topic called "paging". Virtual memory and paging are tightly related, but not the same topic. There are other implementations of virtual memory, such as segmentation.

I could be assuming wrong here, but I'd bet the things you are finding hard to wrap your head around have to do with specific implementations of virtual memory, most likely paging. There is no one way to do paging - there are many implementations and the one your textbook describes is likely not the same as the one that appears in real OSes like Linux/Windows - there are probably subtle differences.

I could blab a thousand paragraphs about paging... but I think that is better left to a different question targeting specifically that topic.

That specifies the how many digits you want it to show.

integer value or * that specifies minimum field width. The result is padded with space characters (by default), if required, on the left when right-justified, or on the right if left-justified. In the case when * is used, the width is specified by an additional argument of type int. If the value of the argument is negative, it results with the - flag specified and positive field width.

ffmpeg -i <input.mp4> -b:v 2048k -s 1000x600 -fs 2048k -vcodec mpeg4 -acodec copy <output.mp4>

• -i input file

• -b:v videobitrate of output video in kilobytes (you have to try)

• -s dimensions of output video

• -fs FILESIZE of output video in kilobytes

• -vcodec videocodec (use ffmpeg -codecs to list all available codecs)

• -acodec audio codec for output video (only copy the audiostream, don't temper)

Try this:

var keys = [];
for (var key in dictionary) {
  if (dictionary.hasOwnProperty(key)) {
    keys.push(key);
  }
}

hasOwnProperty is needed because it's possible to insert keys into the prototype object of dictionary. But you typically don't want those keys included in your list.

For example, if you do this:

Object.prototype.c = 3;
var dictionary = {a: 1, b: 2};

and then do a for...in loop over dictionary, you'll get a and b, but you'll also get c.

I would partially disagree with Milan's suggestion of embedding the requested representation in the URI.

If anyhow possible, URIs should only be used for addressing resources and not for tunneling HTTP methods/verbs. Eventually, specific business action (edit, lock, etc.) could be embedded in the URI if create (POST) or update (PUT) alone do not serve the purpose:

POST http://shonzilla.com/orders/08/165;edit

In the case of requesting a particular representation in URI you would need to disrupt your URI design eventually making it uglier, mixing two distinct REST concepts in the same place (i.e. URI) and making it harder to generically process requests on the server-side. What Milan is suggesting and many are doing the same, incl. Flickr, is exactly this.

Instead, a more RESTful approach would be using a separate place to encode preferred representation by using Accept HTTP header which is used for content negotiation where client tells to the server which content types it can handle/process and server tries to fulfill client's request. This approach is a part of HTTP 1.1 standard, software compliant and supported by web browsers as well.

Compare this:

GET /orders/08/165.xml HTTP/1.1
or
GET /orders/08/165&format=xml HTTP/1.1

to this:

GET /orders/08/165 HTTP/1.1
Accept: application/xml

From a web browser you can request any content type by using setRequestHeader method of XMLHttpRequest object. For example:

function getOrder(year, yearlyOrderId, contentType) {
 var client = new XMLHttpRequest();
 client.open("GET", "/order/" + year + "/" + yearlyOrderId);
 client.setRequestHeader("Accept", contentType);
 client.send(orderDetails);
}

To sum it up: the address, i.e. the URI of a resource should be independent of its representation and XMLHttpRequest.setRequestHeader method allows you to request any representation using the Accept HTTP header.

Cheers!

You can't use a filename like iexplore by itself because the path to internet explorer isn't listed in the PATH environment variable for the system or user.

However any path entered into the PATH environment variable allows you to use just the file name to execute it.

System32 isn't special in this regard as any directory can be added to the PATH variable. Each path is simply delimited by a semi-colon.

For example I have c:\ffmpeg\bin\ and c:\nmap\bin\ in my path environment variable, so I can do things like new ProcessStartInfo("nmap", "-foo") or new ProcessStartInfo("ffplay", "-bar")

The actual PATH variable looks like this on my machine.

%SystemRoot%\system32;C:\FFPlay\bin;C:\nmap\bin;

As you can see you can use other system variables, such as %SystemRoot% to build and construct paths in the environment variable.

So - if you add a path like "%PROGRAMFILES%\Internet Explorer;" to your PATH variable you will be able to use ProcessStartInfo("iexplore");

If you don't want to alter your PATH then simply use a system variable such as %PROGRAMFILES% or %SystemRoot% and then expand it when needed in code. i.e.

string path = Environment.ExpandEnvironmentVariables(
       @"%PROGRAMFILES%\Internet Explorer\iexplore.exe");
var info = new ProcessStartInfo(path);

To link the entire row, you need to define onclick function on your row, which is <tr>element and define a mouse hover in the CSS for tr element to make the mouse pointer to a typical click-hand in web:

In table:

<tr onclick="location.href='http://www.google.com'">
<td>blah</td>
<td>blah</td>
<td><strong>Text</strong></td>
</tr>

In related CSS:

tr:hover {
cursor: pointer;
}

You are missing the else portion. If all the conditions are false then else will work where you haven't declared and returned anything from else branch.

  else
  {
    return false
  }
}

Here is a tidyverse option that might work depending on the data, and some caveats on its usage:

library(tidyverse)

starting_df %>% 
  rownames_to_column() %>% 
  gather(variable, value, -rowname) %>% 
  spread(rowname, value)

rownames_to_column() is necessary if the original dataframe has meaningful row names, otherwise the new column names in the new transposed dataframe will be integers corresponding to the orignal row number. If there are no meaningful row names you can skip rownames_to_column() and replace rowname with the name of the first column in the dataframe, assuming those values are unique and meaningful. Using the tidyr::smiths sample data would be:

smiths %>% 
    gather(variable, value, -subject) %>% 
    spread(subject, value)

Using the example starting_df with the tidyverse approach will throw a warning message about dropping attributes. This is related to converting columns with different attribute types into a single character column. The smiths data will not give that warning because all columns except for subject are doubles.

The earlier answer using as.data.frame(t()) will convert everything to a factor if there are mixed column types unless stringsAsFactors = FALSE is added, whereas the tidyverse option converts everything to a character by default if there are mixed column types.

I read through LOTS of places online to solve this thing. This is the code I wrote to make it work:

ByteArrayInputStream derInputStream = new ByteArrayInputStream(app.certificateString.getBytes());
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate) certificateFactory.generateCertificate(derInputStream);
String alias = "alias";//cert.getSubjectX500Principal().getName();

KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null);
trustStore.setCertificateEntry(alias, cert);
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(trustStore, null);
KeyManager[] keyManagers = kmf.getKeyManagers();

TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");
tmf.init(trustStore);
TrustManager[] trustManagers = tmf.getTrustManagers();

SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(keyManagers, trustManagers, null);
URL url = new URL(someURL);
conn = (HttpsURLConnection) url.openConnection();
conn.setSSLSocketFactory(sslContext.getSocketFactory());

app.certificateString is a String that contains the Certificate, for example:

static public String certificateString=
        "-----BEGIN CERTIFICATE-----\n" +
        "MIIGQTCCBSmgAwIBAgIHBcg1dAivUzANBgkqhkiG9w0BAQsFADCBjDELMAkGA1UE" +
        "BhMCSUwxFjAUBgNVBAoTDVN0YXJ0Q29tIEx0ZC4xKzApBgNVBAsTIlNlY3VyZSBE" +
        ... a bunch of characters...
        "5126sfeEJMRV4Fl2E5W1gDHoOd6V==\n" +
        "-----END CERTIFICATE-----";

I have tested that you can put any characters in the certificate string, if it is self signed, as long as you keep the exact structure above. I obtained the certificate string with my laptop's Terminal command line.

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

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

I would say that the consultant is right in the theory, and you are right in practice. As the saying goes:

In theory, theory and practice are the same. In practice, they are not.

The Java spec says that System.gc suggests to call garbage collection. In practice, it just spawns a thread and runs right away on the Sun JVM.

Although in theory you could be messing up some finely tuned JVM implementation of garbage collection, unless you are writing generic code intended to be deployed on any JVM out there, don't worry about it. If it works for you, do it.

Since someone mentioned efficiency, I've benchmarked the functions given so far out of curiosity:

function startsWith1($str, $char) {
    return strpos($str, $char) === 0;
}
function startsWith2($str, $char) {
    return stripos($str, $char) === 0;
}
function startsWith3($str, $char) {
    return substr($str, 0, 1) === $char;
}
function startsWith4($str, $char){
    return $str[0] === $char;
}
function startsWith5($str, $char){
    return (bool) preg_match('/^' . $char . '/', $str);
}
function startsWith6($str, $char) {
    if (is_null($encoding)) $encoding = mb_internal_encoding();
    return mb_substr($str, 0, mb_strlen($char, $encoding), $encoding) === $char;
}

Here are the results on my average DualCore machine with 100.000 runs each

As you can see, treating the haystack as array to find out the char at the first position is always the fastest solution. It is also always performing at equal speed, regardless of string length. Using strpos is faster than substr for short strings but slower for long strings, when the string does not start with the prefix. The difference is irrelevant though. stripos is incredibly slow with long strings. preg_match performs mostly the same regardless of string length, but is only mediocre in speed. The mb_substr solution performs worst, while probably being more reliable though.

If you want to add a native library without interfering with java.library.path at development time in Eclipse (to avoid including absolute paths and having to add parameters to your launch configuration), you can supply the path to the native libraries location for each Jar in the Java Build Path dialog under Native library location. Note that the native library file name has to correspond to the Jar file name. See also this detailed description.

My preferred way is simply:

NSDate.date.timeIntervalSince1970;

Expand your one liner into multiple lines. Then it becomes easy:

f.write(re.split("Tech ID:|Name:|Account #:",line)[-1])

parts = re.split("Tech ID:|Name:|Account #:",line)
wanted_part = parts[-1]
wanted_part_stripped = wanted_part.strip()
f.write(wanted_part_stripped)

A simple solution would be to just use webView.scrollView.contentSize but I don't know if this works with JavaScript. If there is no JavaScript used this works for sure:

- (void)webViewDidFinishLoad:(UIWebView *)aWebView {
    CGSize contentSize = aWebView.scrollView.contentSize;
    NSLog(@"webView contentSize: %@", NSStringFromCGSize(contentSize));
}

it will print log messages in your developer console (firebug/webkit dev tools/ie dev tools)

Another option: =MID(A1,2,LEN(A1)-2)

Or this (for fun): =RIGHT(LEFT(A1,LEN(A1)-1),LEN(LEFT(A1,LEN(A1)-1))-1)

To convert a time in one timezone to another timezone in Python, you could use datetime.astimezone():

time_in_new_timezone = time_in_old_timezone.astimezone(new_timezone)

Given aware_dt (a datetime object in some timezone), to convert it to other timezones and to print the times in a given time format:

#!/usr/bin/env python3
import pytz  # $ pip install pytz

time_format = "%Y-%m-%d %H:%M:%S%z"
tzids = ['Asia/Shanghai', 'Europe/London', 'America/New_York']
for tz in map(pytz.timezone, tzids):
    time_in_tz = aware_dt.astimezone(tz)
    print(f"{time_in_tz:{time_format}}")

^{If f"" syntax is unavailable, you could replace it with "".format(**vars())}

where you could set aware_dt from the current time in the local timezone:

from datetime import datetime
import tzlocal  # $ pip install tzlocal

local_timezone = tzlocal.get_localzone()
aware_dt = datetime.now(local_timezone) # the current time

Or from the input time string in the local timezone:

naive_dt = datetime.strptime(time_string, time_format)
aware_dt = local_timezone.localize(naive_dt, is_dst=None)

where time_string could look like: '2016-11-19 02:21:42'. It corresponds to time_format = '%Y-%m-%d %H:%M:%S'.

is_dst=None forces an exception if the input time string corresponds to a non-existing or ambiguous local time such as during a DST transition. You could also pass is_dst=False, is_dst=True. See links with more details at Python: How do you convert datetime/timestamp from one timezone to another timezone?

the :checked pseudo-class initially applies to such elements that have the HTML4 selected and checked attributes

Source: w3.org

So, this CSS works, although styling the color is not possible in every browser:

option:checked { color: red; }

An example of this in action, hiding the currently selected item from the drop down list.

option:checked { display:none; }

<select>_x000D_
    <option>A</option>_x000D_
    <option>B</option>_x000D_
    <option>C</option>_x000D_
</select>

To style the currently selected option in the closed dropdown as well, you could try reversing the logic:

select { color: red; }
option:not(:checked) { color: black; } /* or whatever your default style is */

This is also an alternate use of case-when...

In a LinkedList the elements have a reference to the element before and after it. In an ArrayList the data structure is just an array.

1. A LinkedList needs to iterate over N elements to get the Nth element. An ArrayList only needs to return element N of the backing array.

2. The backing array needs to either be reallocated for the new size and the array copied over or every element after the deleted element needs to be moved up to fill the empty space. A LinkedList just needs to set the previous reference on the element after the removed to the one before the removed and the next reference on the element before the removed element to the element after the removed element. Longer to explain, but faster to do.

3. Same reason as deletion here.

To delete the last element from the list just do this.

a = [1,2,3,4,5]
a = a[:-1]
#Output [1,2,3,4] 

For IPv4 addresses, you can use VARCHAR to store them as strings, but also look into storing them as long integesrs INT(11) UNSIGNED. You can use MySQL's INET_ATON() function to convert them to integer representation. The benefit of this is it allows you to do easy comparisons on them, like BETWEEN queries

To access the memory of an object directly (to do a "core dump") you'll need to head into unsafe code.

If you want something more compact than BinaryWriter or a raw memory dump will give you, then you need to write some custom serialisation code that extracts the critical information from the object and packs it in an optimal way.

edit P.S. It's very easy to wrap the BinaryWriter approach into a DeflateStream to compress the data, which will usually roughly halve the size of the data.

You can do a LEFT JOIN and assert the joined column is NULL.

Example:

SELECT * FROM employees a LEFT JOIN eotm_dyn b on (a.joinfield=b.joinfield) WHERE b.name IS NULL

You catch IOException which also catches EOFException, because it is inherited. If you look at the example from the tutorial they underlined that you should catch EOFException - and this is what they do. To solve you problem catch EOFException before IOException:

try
{
    //...
}
catch(EOFException e) {
    //eof - no error in this case
}
catch(IOException e) {
    //something went wrong
    e.printStackTrace(); 
}

Beside that I don't like data flow control using exceptions - it is not the intended use of exceptions and thus (in my opinion) really bad style.

In the adapter you can set the first item as disabled. Below is the sample code

@Override
public boolean isEnabled(int position) {
    if (position == 0) {
        // Disable the first item from Spinner
        // First item will be use for hint
        return false;
    } else {
        return true;
    }
}

And set the first item to grey color.

@Override
public View getDropDownView(int position, View convertView,
                                    ViewGroup parent) {
    View view = super.getDropDownView(position, convertView, parent);
    TextView tv = (TextView) view;
    if (position == 0) {
        // Set the hint text color gray
        tv.setTextColor(Color.GRAY);
    } else {
        tv.setTextColor(Color.BLACK);
    }
    return view;
}

And if the user selects the first item then do nothing.

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    String selectedItemText = (String) parent.getItemAtPosition(position);
    // If user change the default selection
    // First item is disable and it is used for hint
    if (position > 0) {
        // Notify the selected item text
        Toast.makeText(getApplicationContext(), "Selected : " + selectedItemText, Toast.LENGTH_SHORT).show();
    }
}

Refer the below link for detail.

How to add a hint to Spinner in Android

firstSet.equals(secondSet)

It really depends on what you want to do in the comparison logic... ie what happens if you find an element in one set not in the other? Your method has a void return type so I assume you'll do the necessary work in this method.

More fine-grained control if you need it:

if (!firstSet.containsAll(secondSet)) {
  // do something if needs be
}
if (!secondSet.containsAll(firstSet)) {
  // do something if needs be
}

If you need to get the elements that are in one set and not the other.
EDIT: set.removeAll(otherSet) returns a boolean, not a set. To use removeAll(), you'll have to copy the set then use it.

Set one = new HashSet<>(firstSet);
Set two = new HashSet<>(secondSet);
one.removeAll(secondSet);
two.removeAll(firstSet);

If the contents of one and two are both empty, then you know that the two sets were equal. If not, then you've got the elements that made the sets unequal.

You mentioned that the number of records might be high. If the underlying implementation is a HashSet then the fetching of each record is done in O(1) time, so you can't really get much better than that. TreeSet is O(log n).

Try using different quotes for "y" as the identifier quote character is the backtick (“`”). Otherwise MySQL "thinks" that you point to a column named "y".

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

I tried all the methods that are generally posted, Was just about to give up, The signing thing solved it.

Found some app that literally said "apk signer", and it did it.

1. Can someone give a simple definition of what Record is?

A Record<K, T> is an object type whose property keys are K and whose property values are T. That is, keyof Record<K, T> is equivalent to K, and Record<K, T>[K] is (basically) equivalent to T.

2. Is Record<K,T> merely a way of saying "all properties on this object will have type T"? Probably not all objects, since K has some purpose...

As you note, K has a purpose... to limit the property keys to particular values. If you want to accept all possible string-valued keys, you could do something like Record<string, T>, but the idiomatic way of doing that is to use an index signature like { [k: string]: T }.

3. Does the K generic forbid additional keys on the object that are not K, or does it allow them and just indicate that their properties are not transformed to T?

It doesn't exactly "forbid" additional keys: after all, a value is generally allowed to have properties not explicitly mentioned in its type... but it wouldn't recognize that such properties exist:

declare const x: Record<"a", string>;
x.b; // error, Property 'b' does not exist on type 'Record<"a", string>'

and it would treat them as excess properties which are sometimes rejected:

declare function acceptR(x: Record<"a", string>): void;
acceptR({a: "hey", b: "you"}); // error, Object literal may only specify known properties

and sometimes accepted:

const y = {a: "hey", b: "you"};
acceptR(y); // okay

4. With the given example:

   type ThreeStringProps = Record<'prop1' | 'prop2' | 'prop3', string>
   

   Is it exactly the same as this?:

   type ThreeStringProps = {prop1: string, prop2: string, prop3: string}
   

Yes!

Hope that helps. Good luck!

Just wanted to point out another reason this error can be thrown is if you defined a string resource for one translation of your app but did not provide a default string resource.

Example of the Issue:

As you can see below, I had a string resource for a Spanish string "get_started". It can still be referenced in code, but if the phone is not in Spanish it will have no resource to load and crash when calling getString().

values-es/strings.xml

<string name="get_started">SIGUIENTE</string>

Reference to resource

textView.setText(getString(R.string.get_started)

Solution to the Issue

Preventing this is quite simple, just make sure that you always have a default string resource in values/strings.xml so that if the phone is in another language it will always have a resource to fall back to.

values/strings.xml

<string name="get_started">Get Started</string>

values-en/strings.xml

<string name="get_started">Get Started</string>

values-es/strings.xml

<string name="get_started">Siguiente</string>

values-de/strings.xml

<string name="get_started">Ioslegen</string>

go to your cpanel and search "ini editor". You'll get "Multiphp INI Editor" There you select your wordpress directory and put upload_max_filesize = 256M post_max_size = 256M memory_limit = 256M

parseInt($(this).css('marginBottom'), 10);

parseInt will automatically ignore the units.

For example:

var marginBottom = "10px";
marginBottom = parseInt(marginBottom, 10);
alert(marginBottom); // alerts: 10

Query: in sql-server

DECLARE @N INT = 5 --Any random number

SELECT * FROM (
        SELECT ROW_NUMBER() OVER(ORDER BY ID) AS RoNum
              , ID --Add any fields needed here (or replace ID by *)
        FROM TABLE_NAME
) AS tbl 
WHERE @N < RoNum
ORDER BY tbl.ID

This will give rows of Table, where rownumber is starting from @N + 1.

For bash, sth answer is correct. Here is the zsh (my shell of choice) syntax:

mv ~/Linux/Old/^Tux.png ~/Linux/New/

Requires EXTENDED_GLOB shell option to be set.

You can use path.parse(path), for example

const path = require('path');
const { ext } = path.parse('/home/user/dir/file.txt');

This occurs if the password for the database is not given.

default="postgres://postgres:[email protected]:5432/DBname"

Code example:

HashMap<Integer,String> h = new HashMap<Integer,String> ();

h.put(null,null);
h.put(null, "a");

System.out.println(h);

Output:

{null=a}

It overrides the value at key null.

I think it would be handy to use Session.Clear() rather than using Session.Abandon().

Because the values still exist in session after calling later but are removed after calling the former.

I like @Alex Howansky have used 'cmp --silent' for this. But I need both positive and negative response so I use:

cmp --silent file1 file2 && echo '### SUCCESS: Files Are Identical! ###' || echo '### WARNING: Files Are Different! ###'

I can then run this in the terminal or with a ssh to check files against a constant file.

if you need to validate decimal with dots, commas, positives and negatives try this:

Object testObject = "-1.5";
boolean isDecimal = Pattern.matches("^[\\+\\-]{0,1}[0-9]+[\\.\\,]{1}[0-9]+$", (CharSequence) testObject);

Good luck.

A minimalistic example to quickly test the TTS system:

private TextToSpeech textToSpeechSystem;

@Override
protected void onStart() {
  super.onStart();
  textToSpeechSystem = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                String textToSay = "Hello world, this is a test message!";
                textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
            }
        }
   });
}

If you don't use localized messages textToSpeechSystem.setLanguage(..) is important as well, since your users probably don't all have English set as their default language so the pronunciation of the words will be wrong. But for testing TTS in general this snippet is enough

Coobird's answer is the correct, complete one. However, I combined his hints with those from another site to create code that works in my app (iOS/Objective-C), which I wanted to share with anyone who comes here looking for such a thing. Please, if you like/up-vote this answer, do the same for the originals; all I did was "stand on the shoulders of giants."

As for sort-order, my technique is a modified painter's algorithm: each object has (a) an altitude of the base (I call "level") and (b) an X/Y for the "base" or "foot" of the image (examples: avatar's base is at his feet; tree's base is at it's roots; airplane's base is center-image, etc.) Then I just sort lowest to highest level, then lowest (highest on-screen) to highest base-Y, then lowest (left-most) to highest base-X. This renders the tiles the way one would expect.

Code to convert screen (point) to tile (cell) and back:

typedef struct ASIntCell {  // like CGPoint, but with int-s vice float-s
    int x;
    int y;
} ASIntCell;

// Cell-math helper here:
//      http://gamedevelopment.tutsplus.com/tutorials/creating-isometric-worlds-a-primer-for-game-developers--gamedev-6511
// Although we had to rotate the coordinates because...
// X increases NE (not SE)
// Y increases SE (not SW)
+ (ASIntCell) cellForPoint: (CGPoint) point
{
    const float halfHeight = rfcRowHeight / 2.;

    ASIntCell cell;

    cell.y = ((point.x / rfcColWidth) + ((point.y + halfHeight) / rfcRowHeight));

    return cell;

    result.x = (cell.x * rfcColWidth  / 2) + (cell.y * rfcColWidth  / 2);
    result.y = (cell.y * rfcRowHeight / 2) - (cell.x * rfcRowHeight / 2);

    return result;

I will repost how I solved it here just for future references.

How I solved my similar problem

Prerequisite:

1. anaconda already installed
2. Spark already installed (https://spark.apache.org/downloads.html)
3. pyspark already installed (https://anaconda.org/conda-forge/pyspark)

Steps I did (NOTE: set the folder path accordingly to your system)

1. set the following environment variables.
2. SPARK_HOME to 'C:\spark\spark-3.0.1-bin-hadoop2.7'
3. set HADOOP_HOME to 'C:\spark\spark-3.0.1-bin-hadoop2.7'
4. set PYSPARK_DRIVER_PYTHON to 'jupyter'
5. set PYSPARK_DRIVER_PYTHON_OPTS to 'notebook'
6. add 'C:\spark\spark-3.0.1-bin-hadoop2.7\bin;' to PATH system variable.
7. Change the java installed folder directly under C: (Previously java was installed under Program files, so I re-installed directly under C:)
8. so my JAVA_HOME will become like this 'C:\java\jdk1.8.0_271'

now. it works !

A slave isn't a server, it's a client type application. Network clients (almost) never use a specific port. Instead, they ask the OS for a random free port. This works much better since you usually run clients on many machines where the current configuration isn't known in advance. This prevents thousands of "client wouldn't start because port is already in use" bug reports every day.

You need to tell the security department that the slave isn't a server but a client which connects to the server and you absolutely need to have a rule which says client:ANY -> server:FIXED. The client port number should be >= 1024 (ports 1 to 1023 need special permissions) but I'm not sure if you actually gain anything by adding a rule for this - if an attacker can open privileged ports, they basically already own the machine.

If they argue, then ask them why they don't require the same rule for all the web browsers which people use in your company.

That could be done with <a> only:

#twitterbird {
 display: block; /* 'convert' <a> to <div> */
 margin-bottom: 10px;
 background-position: center top;
 background-repeat: no-repeat;
 width: 160px;
 height: 160px;
 background-image: url('twitterbird.png');
}
#twitterbird:hover {
 background-image: url('twitterbird_hover.png');
}

Try this

@Override
public void onResume() {
super.onResume();
items.clear();
items = dbHelper.getItems(); //reload the items from database
adapter = new ItemAdapter(getActivity(), items);//reload the items from database
adapter.notifyDataSetChanged();
}
