All of the answers posted so far are correct, an endpoint is simply one end of a communication channel. In the case of OAuth, there are three endpoints you need to be concerned with:

1. Temporary Credential Request URI (called the Request Token URL in the OAuth 1.0a community spec). This is a URI that you send a request to in order to obtain an unauthorized Request Token from the server / service provider.
2. Resource Owner Authorization URI (called the User Authorization URL in the OAuth 1.0a community spec). This is a URI that you direct the user to to authorize a Request Token obtained from the Temporary Credential Request URI.
3. Token Request URI (called the Access Token URL in the OAuth 1.0a community spec). This is a URI that you send a request to in order to exchange an authorized Request Token for an Access Token which can then be used to obtain access to a Protected Resource.

Hope that helps clear things up. Have fun learning about OAuth! Post more questions if you run into any difficulties implementing an OAuth client.

In my case I had renamed app.config to [appname].exe.config manually. This ended up adding an extra .config suffix to the file name. Solution was to rename it to [appname].exe to eliminate the extra .config extension.

According https://apiblueprint.org/documentation/examples/13-named-endpoints.html is a resource a "general" place of storage of the given entity - e.g. /customers/30654/orders, whereas an endpoint is the concrete action (HTTP Method) over the given resource. So one resource can have multiple endpoints.

An Endpoint is specified as a relative or absolute url that usually results in a response. That response is usually the result of a server-side process that, could, for instance, produce a JSON string. That string can then be consumed by the application that made the call to the endpoint. So, in general endpoints are predefined access points, used within TCP/IP networks to initiate a process and/or return a response. Endpoints could contain parameters passed within the URL, as key value pairs, multiple key value pairs are separated by an ampersand, allowing the endpoint to call, for example, an update/insert process; so endpoints don’t always need to return a response, but a response is always useful, even if it is just to indicate the success or failure of an operation.

I had this error and all the configurations mentioned above were correct however I was still getting "The client and service bindings may be mismatched" error.

What resolved my error, was matching the messageEncoding attribute values in the following node of service and client config files. They were different in mine, service was Text and client Mtom. Changing service to Mtom to match client's, resolved the issue.

<configuration>
  <system.serviceModel>
      <bindings>
           <basicHttpBinding>
              <binding name="BasicHttpBinding_IMySevice" ... messageEncoding="Mtom">
              ...
              </binding>
           </basicHttpBinding>
      </bindings>
  </system.serviceModel>
</configuration>

According to the above,i found three ways to solve the problem.

1. AnotherMongoDocument._id.toString()
2. JSON.stringify(AnotherMongoDocument._id)
3. results.userId.equals(AnotherMongoDocument._id)

Mac OS X doesn't have apt-get. There is a package manager called Homebrew that is used instead.

This command would be:

brew install python

Use Homebrew to install packages that you would otherwise use apt-get for.

The page I linked to has an up-to-date way of installing homebrew, but at present, you can install Homebrew as follows:

Type the following in your Mac OS X terminal:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

After that, usage of Homebrew is brew install <package>.

One of the prerequisites for Homebrew are the XCode command line tools.

1. Install XCode from the App Store.
2. Follow the directions in this Stack Overflow answer to install the XCode Command Line Tools.

Background

A package manager (like apt-get or brew) just gives your system an easy and automated way to install packages or libraries. Different systems use different programs. apt and its derivatives are used on Debian based linux systems. Red Hat-ish Linux systems use rpm (or at least they did many, many, years ago). yum is also a package manager for RedHat based systems.

Alpine based systems use apk.

Warning

As of 25 April 2016, homebrew opts the user in to sending analytics by default. This can be opted out of in two ways:

Setting an environment variable:

1. Open your favorite environment variable editor.
2. Set the following: HOMEBREW_NO_ANALYTICS=1 in whereever you keep your environment variables (typically something like ~/.bash_profile)
3. Close the file, and either restart the terminal or source ~/.bash_profile.

Running the following command:

brew analytics off

the analytics status can then be checked with the command:

brew analytics

Here's how I interpret it:

int *something[n];

Note on precedence: array subscript operator ([]) has higher priority than dereference operator (*).

So, here we will apply the [] before *, making the statement equivalent to:

int *(something[i]);

Note on how a declaration makes sense: int num means num is an int, int *ptr or int (*ptr) means, (value at ptr) is an int, which makes ptr a pointer to int.

This can be read as, (value of the (value at ith index of the something)) is an integer. So, (value at the ith index of something) is an (integer pointer), which makes the something an array of integer pointers.

In the second one,

int (*something)[n];

To make sense out of this statement, you must be familiar with this fact:

Note on pointer representation of array: somethingElse[i] is equivalent to *(somethingElse + i)

So, replacing somethingElse with (*something), we get *(*something + i), which is an integer as per declaration. So, (*something) given us an array, which makes something equivalent to (pointer to an array).

If our CustomTableSeeder is in same directory with DatabaseSeeder we should use like below:

$this->call('database\seeds\CustomTableSeeder');

in our DatabaseSeeder File; then another error will be thrown that says: 'DB Class not found' then we should add our DB facade to our CustomTableSeeder File like below:

use Illuminate\Support\Facades\DB;

it worked for me!

To find any sub-string from large string:

string_value:=('This is String,Please search string 'Ple');

Then to find the string 'Ple' from String_value we can do as:

select substr(string_value,instr(string_value,'Ple'),length('Ple')) from dual;

You will find result: Ple

your device can be the problem too

'cmd package install-create -r -t --full  -S 85640035' returns error 'Unknown failure: Exception occurred while executing:

when there is not enough storage

Lazy loading - is good when handling with pagination like on page load list of users appear which contains 10 users and as the user scrolls down the page an api call brings next 10 users.Its good when you don't want to load enitire data at once as it would take more time and would give bad user experience.

Eager loading - is good as other people suggested when there are not much relations and fetch entire data at once in single call to database

Working from what you've given I'll assume you want to check that someone has NOT entered any letters other than the ones you've listed. For that to work you want to search for any characters other than those listed:

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

And use that in a match in your code, something like:

if ( /[^A-Za-z0-9_.]/.match( your_input_string ) ) {
   alert( "you have entered invalid data" );
}

Hows that?

This solution does the following:

• Uses the ES6 spread operator to convert the NodeList of all divs to an array.

• Provides output if the div contains the query string, not just if it exactly equals the query string (which happens for some of the other answers). e.g. It should provide output not just for 'SomeText' but also for 'SomeText, text continues'.

• Outputs the entire div contents, not just the query string. e.g. For 'SomeText, text continues' it should output that whole string, not just 'SomeText'.

• Allows for multiple divs to contain the string, not just a single div.

[...document.querySelectorAll('div')]      // get all the divs in an array_x000D_
  .map(div => div.innerHTML)               // get their contents_x000D_
  .filter(txt => txt.includes('SomeText')) // keep only those containing the query_x000D_
  .forEach(txt => console.log(txt));       // output the entire contents of those

<div>SomeText, text continues.</div>_x000D_
<div>Not in this div.</div>_x000D_
<div>Here is more SomeText.</div>

Not tried it with combo boxes but this has worked for me with other controls...

He uses the adorner layer here to display a watermark.

I'm surprised there's been no mention of filter_var here for this being such an old question...

PHP has a built in method of doing this using sanitization filters. Specifically, the one to use in this situation is FILTER_SANITIZE_NUMBER_FLOAT with the FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND flags. Like so:

$numeric_filtered = filter_var("AR3,373.31", FILTER_SANITIZE_NUMBER_FLOAT,
    FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND);
echo $numeric_filtered; // Will print "3,373.31"

It might also be worthwhile to note that because it's built-in to PHP, it's slightly faster than using regex with PHP's current libraries (albeit literally in nanoseconds).

Maybe you have some rows in the table that you want to create de FK.

Run the migration with foreign_key_checks OFF Insert only those records that have corresponding id field in contents table.

You miss the from clause

SELECT *  from TCCAWZTXD.TCC_COIL_DEMODATA WHERE CURRENT_INSERTTIME  BETWEEN(CURRENT_TIMESTAMP)-5 minutes AND CURRENT_TIMESTAMP

It depends on what next is.

If it's a string (as in your example), then in checks for substrings.

>>> "in" in "indigo"
True
>>> "in" in "violet"
False
>>> "0" in "10"
True
>>> "1" in "10"
True

If it's a different kind of iterable (list, tuple, set, dictionary...), then in checks for membership.

>>> "in" in ["in", "out"]
True
>>> "in" in ["indigo", "violet"]
False

In a dictionary, membership is seen as "being one of the keys":

>>> "in" in {"in": "out"}
True
>>> "in" in {"out": "in"}
False

At the extreme ranges, an unsigned int can become larger than an int.
Therefore, the compiler generates a warning. If you are sure that this is not a problem, feel free to cast the types to the same type so the warning disappears (use C++ cast so that they are easy to spot).

Alternatively, make the variables the same type to stop the compiler from complaining.
I mean, is it possible to have a negative padding? If so then keep it as an int. Otherwise you should probably use unsigned int and let the stream catch the situations where the user types in a negative number.

I have the same problem that you describe although I'm building up my LatLngBounds as proposed by above. The problem is that things are async and calling map.fitBounds() at the wrong time may leave you with a result like in the Q. The best way I found is to place the call in an idle handler like this:

google.maps.event.addListenerOnce(map, 'idle', function() {
    map.fitBounds(markerBounds);
});

Something like this should do it:

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

There's an excellent module for flow control in node.js called asyncblock. If wrapping the code in a function is OK for your case, the following sample may be considered:

var asyncblock = require('asyncblock');
var exec = require('child_process').exec;

asyncblock(function (flow) {
    exec('node -v', flow.add());
    result = flow.wait();
    console.log(result);    // There'll be trailing \n in the output

    // Some other jobs
    console.log('More results like if it were sync...');
});

I know it's a bit late, but I think there are some people who are interested in performance.

I've done a little performance test. I wrote a class "NumberHolder" which, well, holds an Integer. You can either read that Integer by using the getter method anInstance.getNumber() or by directly accessing the number by using anInstance.number. My programm reads the number 1,000,000,000 times, via both ways. That process is repeated five times and the time is printed. I've got the following result:

Time 1: 953ms, Time 2: 741ms
Time 1: 655ms, Time 2: 743ms
Time 1: 656ms, Time 2: 634ms
Time 1: 637ms, Time 2: 629ms
Time 1: 633ms, Time 2: 625ms

(Time 1 is the direct way, Time 2 is the getter)

You see, the getter is (almost) always a bit faster. Then I tried with different numbers of cycles. Instead of 1 million, I used 10 million and 0.1 million. The results:

10 million cycles:

Time 1: 6382ms, Time 2: 6351ms
Time 1: 6363ms, Time 2: 6351ms
Time 1: 6350ms, Time 2: 6363ms
Time 1: 6353ms, Time 2: 6357ms
Time 1: 6348ms, Time 2: 6354ms

With 10 million cycles, the times are almost the same. Here are 100 thousand (0.1 million) cycles:

Time 1: 77ms, Time 2: 73ms
Time 1: 94ms, Time 2: 65ms
Time 1: 67ms, Time 2: 63ms
Time 1: 65ms, Time 2: 65ms
Time 1: 66ms, Time 2: 63ms

Also with different amounts of cycles, the getter is a little bit faster than the regular way. I hope this helped you.

I'm working with

jQuery Autocomplete

I tried looking for an event as described above, but when the request function fires it doesn't seem to be available. I used this.element.attr("id") to get the element's ID instead, and it seems to work fine.

If we are directly use data from csv it will give combine data based on comma separation value as it is .csv file.

user1 = pd.read_csv('dataset/1.csv')

If you want to add column names using pandas, you have to do something like this. But below code will not show separate header for your columns.

col_names=['TIME', 'X', 'Y', 'Z'] 
user1 = pd.read_csv('dataset/1.csv', names=col_names)

To solve above problem we have to add extra filled which is supported by pandas, It is header=None

user1 = pd.read_csv('dataset/1.csv', names=col_names, header=None)

just do

npm i --save circular-json

then in your js file

const CircularJSON = require('circular-json');
...
const json = CircularJSON.stringify(obj);

https://github.com/WebReflection/circular-json

NOTE: I have nothing to do with this package. But I do use it for this.

Update 2020

Please note CircularJSON is in maintenance only and flatted is its successor.

Probably the most definitive is Figure B.1(d) of the ggplot2 book, the appendices of which are available at http://ggplot2.org/book/appendices.pdf.

However, it is not quite that simple. hjust and vjust as described there are how it works in geom_text and theme_text (sometimes). One way to think of it is to think of a box around the text, and where the reference point is in relation to that box, in units relative to the size of the box (and thus different for texts of different size). An hjust of 0.5 and a vjust of 0.5 center the box on the reference point. Reducing hjust moves the box right by an amount of the box width times 0.5-hjust. Thus when hjust=0, the left edge of the box is at the reference point. Increasing hjust moves the box left by an amount of the box width times hjust-0.5. When hjust=1, the box is moved half a box width left from centered, which puts the right edge on the reference point. If hjust=2, the right edge of the box is a box width left of the reference point (center is 2-0.5=1.5 box widths left of the reference point. For vertical, less is up and more is down. This is effectively what that Figure B.1(d) says, but it extrapolates beyond [0,1].

But, sometimes this doesn't work. For example

DF <- data.frame(x=c("a","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p + opts(axis.text.x=theme_text(vjust=0))
p + opts(axis.text.x=theme_text(vjust=1))
p + opts(axis.text.x=theme_text(vjust=2))

The three latter plots are identical. I don't know why that is. Also, if text is rotated, then it is more complicated. Consider

p + opts(axis.text.x=theme_text(hjust=0, angle=90))
p + opts(axis.text.x=theme_text(hjust=0.5 angle=90))
p + opts(axis.text.x=theme_text(hjust=1, angle=90))
p + opts(axis.text.x=theme_text(hjust=2, angle=90))

The first has the labels left justified (against the bottom), the second has them centered in some box so their centers line up, and the third has them right justified (so their right sides line up next to the axis). The last one, well, I can't explain in a coherent way. It has something to do with the size of the text, the size of the widest text, and I'm not sure what else.

string helloOriginal = "Hello! World!";
string newString = helloOriginal.Substring(0,helloOriginal.LastIndexOf('!'));

If the number of fields in the CSV is constant then you could do something like this:

select a[1], a[2], a[3], a[4]
from (
    select regexp_split_to_array('a,b,c,d', ',')
) as dt(a)

For example:

=> select a[1], a[2], a[3], a[4] from (select regexp_split_to_array('a,b,c,d', ',')) as dt(a);
 a | a | a | a 
---+---+---+---
 a | b | c | d
(1 row)

If the number of fields in the CSV is not constant then you could get the maximum number of fields with something like this:

select max(array_length(regexp_split_to_array(csv, ','), 1))
from your_table

and then build the appropriate a[1], a[2], ..., a[M] column list for your query. So if the above gave you a max of 6, you'd use this:

select a[1], a[2], a[3], a[4], a[5], a[6]
from (
    select regexp_split_to_array(csv, ',')
    from your_table
) as dt(a)

You could combine those two queries into a function if you wanted.

For example, give this data (that's a NULL in the last row):

=> select * from csvs;
     csv     
-------------
 1,2,3
 1,2,3,4
 1,2,3,4,5,6

(4 rows)

=> select max(array_length(regexp_split_to_array(csv, ','), 1)) from csvs;
 max 
-----
   6
(1 row)

=> select a[1], a[2], a[3], a[4], a[5], a[6] from (select regexp_split_to_array(csv, ',') from csvs) as dt(a);
 a | a | a | a | a | a 
---+---+---+---+---+---
 1 | 2 | 3 |   |   | 
 1 | 2 | 3 | 4 |   | 
 1 | 2 | 3 | 4 | 5 | 6
   |   |   |   |   | 
(4 rows)

Since your delimiter is a simple fixed string, you could also use string_to_array instead of regexp_split_to_array:

select ...
from (
    select string_to_array(csv, ',')
    from csvs
) as dt(a);

Thanks to Michael for the reminder about this function.

You really should redesign your database schema to avoid the CSV column if at all possible. You should be using an array column or a separate table instead.

One way to get the list of distinct column names from the database is to use distinct() in conjunction with values().

In your case you can do the following to get the names of distinct categories:

q = ProductOrder.objects.values('Category').distinct()
print q.query # See for yourself.

# The query would look something like
# SELECT DISTINCT "app_productorder"."category" FROM "app_productorder"

There are a couple of things to remember here. First, this will return a ValuesQuerySet which behaves differently from a QuerySet. When you access say, the first element of q (above) you'll get a dictionary, NOT an instance of ProductOrder.

Second, it would be a good idea to read the warning note in the docs about using distinct(). The above example will work but all combinations of distinct() and values() may not.

PS: it is a good idea to use lower case names for fields in a model. In your case this would mean rewriting your model as shown below:

class ProductOrder(models.Model):
    product  = models.CharField(max_length=20, primary_key=True)
    category = models.CharField(max_length=30)
    rank = models.IntegerField()

They are signals that application developers use. The kernel shouldn't ever send these to a process. You can send them using kill(2) or using the utility kill(1).

If you intend to use signals for synchronization you might want to check real-time signals (there's more of them, they are queued, their delivery order is guaranteed etc).

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

You can use the pseudo-selector :checkbox with a call to jQuery's is function:

$('#myinput').is(':checkbox')

That sort of functionality is going to require some Javascript, but it is probably possible just to use CSS (in browsers other than IE6&7).

With java 8 you can try this:

import org.json.JSONException;
import org.json.JSONObject;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

public class JSONUtil {

    public static JSONObject parseJSONFile(String filename) throws JSONException, IOException {
        String content = new String(Files.readAllBytes(Paths.get(filename)));
        return new JSONObject(content);
    }

    public static void main(String[] args) throws IOException, JSONException {
        String filename = "path/to/file/abc.json";
        JSONObject jsonObject = parseJSONFile(filename);

        //do anything you want with jsonObject
    }
}

Worked in Swift 3

NSDecimalNumber(string: "Your string") 

You can use the wmic command:

wmic path CIM_LogicalDevice where "Description like 'USB%'" get /value

I think the only way to do this is to run another machine in parallel and use that machine to issue commands to your android box similar to how you would with a phone. If you have issues with the IP changing you can reserve an ip on your router and have the machine grab that one instead of asking the routers DHCP for one. This way you can ping the machine and figure out if it's done rebooting to continue the script.

Adam explain well in his answer But I used this way. I think this is easiest way to understand time comparison in java

First create 3 calender object with set your time only , Hour and min.

then get GMT milliseconds of that time and simply compare.

Ex.

Calendar chechDateTime = Calendar.getInstance();
chechDateTime.set(Calendar.MILLISECOND, 0);
chechDateTime.set(Calendar.SECOND, 0);
chechDateTime.set(Calendar.HOUR, 11);
chechDateTime.set(Calendar.MINUTE, 22);


Calendar startDateTime = Calendar.getInstance();
startDateTime.set(Calendar.MILLISECOND, 0);
startDateTime.set(Calendar.SECOND, 0);
startDateTime.set(Calendar.HOUR, 10);
startDateTime.set(Calendar.MINUTE, 0);

Calendar endDateTime = Calendar.getInstance();
endDateTime.set(Calendar.MILLISECOND, 0);
endDateTime.set(Calendar.SECOND, 0);
endDateTime.set(Calendar.HOUR, 18);
endDateTime.set(Calendar.MINUTE, 22);

 long chechDateTimeMilliseconds=chechDateTime.getTime().getTime();
 long startDateTimeMilliseconds=startDateTime.getTime().getTime();
 long endDateTimeMilliseconds=endDateTime.getTime().getTime();


System.out.println("chechDateTime : "+chechDateTimeMilliseconds);
System.out.println("startDateTime "+startDateTimeMilliseconds);
System.out.println("endDateTime "+endDateTimeMilliseconds);



if(chechDateTimeMilliseconds>=startDateTimeMilliseconds && chechDateTimeMilliseconds <= endDateTimeMilliseconds ){
       System.out.println("In between ");
    }else{
         System.out.println("Not In between ");
    }

Output will look like this :

chechDateTime : 1397238720000
startDateTime 1397233800000
endDateTime 1397263920000
In between

An idea would be that display:flex; with flex-direction: row; is filling the container div with .flex-1 and .flex-2, but that does not mean that .flex-2 has a default height:100%;, even if it is extended to full height.

And to have a child element (.flex-2-child) with height:100%;, you'll need to set the parent to height:100%; or use display:flex; with flex-direction: row; on the .flex-2 div too.

From what I know, display:flex will not extend all your child elements height to 100%.

A small demo, removed the height from .flex-2-child and used display:flex; on .flex-2: http://jsfiddle.net/2ZDuE/3/

Modern approach

The modern way, for the entire navigation controller… do this once, when your navigation controller's root view is loaded.

[self.navigationController.navigationBar setTitleTextAttributes:
   @{NSForegroundColorAttributeName:[UIColor yellowColor]}];

However, this doesn't seem have an effect in subsequent views.

Classic approach

The old way, per view controller (these constants are for iOS 6, but if want to do it per view controller on iOS 7 appearance you'll want the same approach but with different constants):

You need to use a UILabel as the titleView of the navigationItem.

The label should:

• Have a clear background color (label.backgroundColor = [UIColor clearColor]).
• Use bold 20pt system font (label.font = [UIFont boldSystemFontOfSize: 20.0f]).
• Have a shadow of black with 50% alpha (label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5]).
• You'll want to set the text alignment to centered as well (label.textAlignment = NSTextAlignmentCenter (UITextAlignmentCenter for older SDKs).

Set the label text color to be whatever custom color you'd like. You do want a color that doesn't cause the text to blend into shadow, which would be difficult to read.

I worked this out through trial and error, but the values I came up with are ultimately too simple for them not to be what Apple picked. :)

If you want to verify this, drop this code into initWithNibName:bundle: in PageThreeViewController.m of Apple's NavBar sample. This will replace the text with a yellow label. This should be indistinguishable from the original produced by Apple's code, except for the color.

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self)
    {
        // this will appear as the title in the navigation bar
        UILabel *label = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
        label.backgroundColor = [UIColor clearColor];
        label.font = [UIFont boldSystemFontOfSize:20.0];
        label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
        label.textAlignment = NSTextAlignmentCenter;
                           // ^-Use UITextAlignmentCenter for older SDKs.
        label.textColor = [UIColor yellowColor]; // change this color
        self.navigationItem.titleView = label;
        label.text = NSLocalizedString(@"PageThreeTitle", @"");
        [label sizeToFit];
    }

    return self;
}

Edit: Also, read Erik B's answer below. My code shows the effect, but his code offers a simpler way to drop this into place on an existing view controller.

If

git config --global core.filemode false

does not work for you, do it manually:

cd into yourLovelyProject folder

cd into .git folder:

cd .git

edit the config file:

nano config

change true to false

[core]
        repositoryformatversion = 0
        filemode = true

->

[core]
        repositoryformatversion = 0
        filemode = false

save, exit, go to upper folder:

cd ..

reinit the git

git init

you are done!

This wll work.

There is a HUGE difference between VARCHAR and TEXT. While VARCHAR fields can be indexed, TEXT fields cannot. VARCHAR type fields are stored inline while TEXT are stored offline, only pointers to TEXT data is actually stored in the records.

If you have to index your field for faster search, update or delete than go for VARCHAR, no matter how big. A VARCHAR(10000000) will never be the same as a TEXT field bacause these two data types are different in nature.

• If you use you field only for archiving
• you don't care about data speed retrival
• you care about speed but you will use the operator '%LIKE%' in your search query so indexing will not help much
• you can't predict a limit of the data length

than go for TEXT.

Within a Python scope, any assignment to a variable not already declared within that scope creates a new local variable unless that variable is declared earlier in the function as referring to a globally scoped variable with the keyword global.

Let's look at a modified version of your pseudocode to see what happens:

# Here, we're creating a variable 'x', in the __main__ scope.
x = 'None!'

def func_A():
  # The below declaration lets the function know that we
  #  mean the global 'x' when we refer to that variable, not
  #  any local one

  global x
  x = 'A'
  return x

def func_B():
  # Here, we are somewhat mislead.  We're actually involving two different
  #  variables named 'x'.  One is local to func_B, the other is global.

  # By calling func_A(), we do two things: we're reassigning the value
  #  of the GLOBAL x as part of func_A, and then taking that same value
  #  since it's returned by func_A, and assigning it to a LOCAL variable
  #  named 'x'.     
  x = func_A() # look at this as: x_local = func_A()

  # Here, we're assigning the value of 'B' to the LOCAL x.
  x = 'B' # look at this as: x_local = 'B'

  return x # look at this as: return x_local

In fact, you could rewrite all of func_B with the variable named x_local and it would work identically.

The order matters only as far as the order in which your functions do operations that change the value of the global x. Thus in our example, order doesn't matter, since func_B calls func_A. In this example, order does matter:

def a():
  global foo
  foo = 'A'

def b():
  global foo
  foo = 'B'

b()
a()
print foo
# prints 'A' because a() was the last function to modify 'foo'.

Note that global is only required to modify global objects. You can still access them from within a function without declaring global. Thus, we have:

x = 5

def access_only():
  return x
  # This returns whatever the global value of 'x' is

def modify():
  global x
  x = 'modified'
  return x
  # This function makes the global 'x' equal to 'modified', and then returns that value

def create_locally():
  x = 'local!'
  return x
  # This function creates a new local variable named 'x', and sets it as 'local',
  #  and returns that.  The global 'x' is untouched.

Note the difference between create_locally and access_only -- access_only is accessing the global x despite not calling global, and even though create_locally doesn't use global either, it creates a local copy since it's assigning a value.

The confusion here is why you shouldn't use global variables.

JVM does not find java.exe. It doesn't even call it. java.exe is called by the operating system (Windows in this case).

JAVA_HOME is just a convention, usually used by Tomcat, other Java EE app servers and build tools such as Gradle to find where Java lives.

The important thing from your point of view is that the Java /bin directory be on your PATH so Windows can find the .exe tools that ship with the JDK: javac.exe, java.exe, jar.exe, etc.

CSS

I used to use the following from CSS-Tricks:

.transparent_class {
  /* IE 8 */
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";

  /* IE 5-7 */
  filter: alpha(opacity=50);

  /* Netscape */
  -moz-opacity: 0.5;

  /* Safari 1.x */
  -khtml-opacity: 0.5;

  /* Good browsers */
  opacity: 0.5;
}

Compass

However, a better solution is to use the Opacity Compass mixin, all you need to do is to @include opacity(0.1); and it will take care of any cross-browser issues for you. You can find an example here.

table tr td:nth-child(2) {
    background: #ccc;
}

For php, \n should work for you!

It's simple

pd.factorize(df.purchase)[0]

Example:

labels, uniques = pd.factorize(['b', 'b', 'a', 'c', 'b'])`

labels
# array([0, 0, 1, 2, 0])

uniques
# array(['b', 'a', 'c'], dtype=object)

You don't have to set either of them. PYTHONPATH can be set to point to additional directories with private libraries in them. If PYTHONHOME is not set, Python defaults to using the directory where python.exe was found, so that dir should be in PATH.

Maybe you could do it this way, this program is a demonstration of how to trap a segmentation fault and shells out to a debugger (this is the original code used under AIX) and prints the stack trace up to the point of a segmentation fault. You will need to change the sprintf variable to use gdb in the case of Linux.

For the substition impaired here is a real example from GitHub.com to a local directory:

svn ls https://github.com/rdcarp/playing-cards/trunk/PumpkinSoup.PlayingCards.Interfaces
svn export https://github.com/rdcarp/playing-cards/trunk/PumpkinSoup.PlayingCards.Interfaces /temp/SvnExport/Washburn

See: Download a single folder or directory from a GitHub repo for more details.

What do you thing about this approach?

with open(filename) as data:
    datalines = (line.rstrip('\r\n') for line in data)
    for line in datalines:
        ...do something awesome...

Generator expression avoids loading whole file into memory and with ensures closing the file

1. Define two tables (example A and B), with their own primary key
2. Define a column in Table A as having a Foreign key relationship based on the primary key of Table B

This means that Table A can have one or more records relating to a single record in Table B.

If you already have the tables in place, use the ALTER TABLE statement to create the foreign key constraint:

ALTER TABLE A ADD CONSTRAINT fk_b FOREIGN KEY (b_id) references b(id) 

• fk_b: Name of the foreign key constraint, must be unique to the database
• b_id: Name of column in Table A you are creating the foreign key relationship on
• b: Name of table, in this case b
• id: Name of column in Table B

This one liner will do:

echo "$(tail -n +2 "$FILE")" > "$FILE"

It works, since tail is executed prior to echo and then the file is unlocked, hence no need for a temp file.

The biggest question is for what purpose?

Your code is nearly as comprehensive as it could be - but I see that if you spot what looks like a proxy added header, you use that INSTEAD of the CLIENT_IP, however if you want this information for audit purposes then be warned - its very easy to fake.

Certainly you should never use IP addresses for any sort of authentication - even these can be spoofed.

You could get a better measurement of the client ip address by pushing out a flash or java applet which connects back to the server via a non-http port (which would therefore reveal transparent proxies or cases where the proxy-injected headers are false - but bear in mind that, where the client can ONLY connect via a web proxy or the outgoing port is blocked, there will be no connection from the applet.

If you want to center the th of all tables:
table th{ text-align: center; }

If you only want to center the th of a table with a determined id:
table#tableId th{ text-align: center; }

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);
}

From the Jquery docs: you specify the async option to be false to get a synchronous Ajax request. Then your callback can set some data before your mother function proceeds.

Here's what your code would look like if changed as suggested:

beforecreate: function(node,targetNode,type,to) {
    jQuery.ajax({
         url:    url,
         success: function(result) {
                      if(result.isOk == false)
                          alert(result.message);
                  },
         async:   false
    });          
}

this is because $.ajax is the only request type that you can set the asynchronousity for

You can Change it from:

Menu Settings -> Style Configurator

See on screenshot:

jQuery will do the job. You can use either jQuery.ajax function, which is general one for performing ajax calls, or its wrappers: jQuery.get, jQuery.post for getting/posting data. Its very easy to use, for example, check out this tutorial, which shows how to use jQuery with PHP.

For my projects I made this solution (RecyclerView with setEmptyView method):

public class RecyclerViewEmptySupport extends RecyclerView {
    private View emptyView;

    private AdapterDataObserver emptyObserver = new AdapterDataObserver() {


        @Override
        public void onChanged() {
            Adapter<?> adapter =  getAdapter();
            if(adapter != null && emptyView != null) {
                if(adapter.getItemCount() == 0) {
                    emptyView.setVisibility(View.VISIBLE);
                    RecyclerViewEmptySupport.this.setVisibility(View.GONE);
                }
                else {
                    emptyView.setVisibility(View.GONE);
                    RecyclerViewEmptySupport.this.setVisibility(View.VISIBLE);
                }
            }

        }
    };

    public RecyclerViewEmptySupport(Context context) {
        super(context);
    }

    public RecyclerViewEmptySupport(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public RecyclerViewEmptySupport(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setAdapter(Adapter adapter) {
        super.setAdapter(adapter);

        if(adapter != null) {
            adapter.registerAdapterDataObserver(emptyObserver);
        }

        emptyObserver.onChanged();
    }

    public void setEmptyView(View emptyView) {
        this.emptyView = emptyView;
    }
}

And you should use it instead of RecyclerView class:

<com.maff.utils.RecyclerViewEmptySupport android:id="@+id/list1"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    />

<TextView android:id="@+id/list_empty"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Empty"
    />

and

RecyclerViewEmptySupport list = 
    (RecyclerViewEmptySupport)rootView.findViewById(R.id.list1);
list.setLayoutManager(new LinearLayoutManager(context));
list.setEmptyView(rootView.findViewById(R.id.list_empty));

try/catch is scripted syntax. So any time you are using declarative syntax to use something from scripted in general you can do so by enclosing the scripted syntax in the scripts block in a declarative pipeline. So your try/catch should go inside stage >steps >script.

This holds true for any other scripted pipeline syntax you would like to use in a declarative pipeline as well.

df['bar'] = df.bar.map(str) + " is " + df.foo.

1. brew install ios-deploy
2. npx react-native run-ios --device

The second command will run the app on the first connected device.

I just had to revisit this issue today and found Get the source directory of a Bash script from within the script itself:

If you want client IP and your server is behind aws elb, then user the following code. Tested for laravel 5.3

$elbSubnet = '172.31.0.0/16';
Request::setTrustedProxies([$elbSubnet]);
$clientIp = $request->ip();

There are $watchGroup and $watchCollection as well. Specifically, $watchGroup is really helpful if you want to call a function to update an object which has multiple properties in a view that is not dom object, for e.g. another view in canvas, WebGL or server request.

Here, the documentation link.

String.split seems to be much slower than StringTokenizer. The only advantage with split is that you get an array of the tokens. Also you can use any regular expressions in split. org.apache.commons.lang.StringUtils has a split method which works much more faster than any of two viz. StringTokenizer or String.split. But the CPU utilization for all the three is nearly the same. So we also need a method which is less CPU intensive, which I am still not able to find.

If you want to get the index of the selected radio button inside a control you can use this method:

public static int getCheckedRadioButton(Control c)
{
    int i;
    try
    {
        Control.ControlCollection cc = c.Controls;
        for (i = 0; i < cc.Count; i++)
        {
            RadioButton rb = cc[i] as RadioButton;
            if (rb.Checked)
            {
                return i;
            }
        }
    }
    catch
    {
        i = -1;
    }
    return i;
}

Example use:

int index = getCheckedRadioButton(panel1);

The code isn't that well tested, but it seems the index order is from left to right and from top to bottom, as when reading a text. If no radio button is found, the method returns -1.

Update: It turned out my first attempt didn't work if there's no radio button inside the control. I added a try and catch block to fix that, and the method now seems to work.

Try these to clarify the issue of right alignment in float point printing

printf(" 4|%4.1lf\n", 8.9);
printf("04|%04.1lf\n", 8.9);

the output is

 4| 8.9
04|08.9

I would like to give you also the idea to disable an <option> with a given defined value (not innerhtml). I recommend to it with jQuery to get the simplest way. See my sample below.

HTML

Status:  
<div id="option">
   <select class="status">
      <option value="hand" selected>Hand</option>
      <option value="simple">Typed</option>
      <option value="printed">Printed</option>
   </select>
</div>

Javascript

The idea here is how to disable Printed option when current Status is Hand

var status = $('#option').find('.status');//to get current the selected value
var op = status.find('option');//to get the elements for disable attribute
(status.val() == 'hand')? op[2].disabled = true: op[2].disabled = false;

You may see how it works here:

For anyone who finds this page looking for unix timestamp w/ milliseconds, the documentation says

moment().valueOf()

or

+moment();

you can also get it through moment().format('x') (or .format('X') [capital X] for unix seconds with decimal milliseconds), but that will give you a string. Which moment.js won't actually parse back afterwards, unless you convert/cast it back to a number first.

Here is an extension method for setting unique indexes more fluently:

public static class MappingExtensions
{
    public static PrimitivePropertyConfiguration IsUnique(this PrimitivePropertyConfiguration configuration)
    {
        return configuration.HasColumnAnnotation("Index", new IndexAnnotation(new IndexAttribute { IsUnique = true }));
    }
}

Usage:

modelBuilder 
    .Entity<Person>() 
    .Property(t => t.Name)
    .IsUnique();

Will generate migration such as:

public partial class Add_unique_index : DbMigration
{
    public override void Up()
    {
        CreateIndex("dbo.Person", "Name", unique: true);
    }

    public override void Down()
    {
        DropIndex("dbo.Person", new[] { "Name" });
    }
}

I use port 465 all the time.

The answer by danorton is outdated. As he and Wikipedia say, port 465 was initially planned for the SMTPS encryption and quickly deprecated 15 years ago. But a lot of ISPs are still using port 465, especially to be in compliance with the current recommendations of RFC 8314, which encourages the use of implicit TLS instead of the use of the STARTTLS command with port 587. (See section 3.3). Using port 465 is the only way to begin an implicitly secure session with an SMTP server that is acting as a mail submission agent (MSA).

Basically, what RFC 8314 recommends is that cleartext email exchanges be abandoned and that all three common IETF mail protocols be used only in implicit TLS sessions for consistency when possible. The recommended secure ports, then, are 465, 993, and 995 for SMTPS, IMAP4S, and POP3S, respectively.

Although RFC 8314 certainly allows the continued use of explicit TLS with port 587 and the STARTTLS command, doing so opens up the mail user agent (MUA, the mail client) to a downgrade attack where a man-in-the-middle intercepts the STARTTLS request to upgrade to TLS security but denies it, thus forcing the session to remain in cleartext.

If your using Node.js or writing JavaScript with browserify, consider the "once" npm module:

var once = require('once')

function load (file, cb) {
  cb = once(cb)
  loader.load('file')
  loader.once('load', cb)
  loader.once('error', cb)
}

In my case, I was using both @RunWith(MockitoJUnitRunner.class) and MockitoAnnotations.initMocks(this). When I removed MockitoAnnotations.initMocks(this) it worked correctly.

This might be your problem:

height: .05em;

Chrome is a bit funky with decimals, so try a fixed-pixel height:

height: 2px;

If you are using Sublime Text 3, using a build system to open the file opens the most current version and provides a convenient way to load it via [CTRL + B] To set up a build system that opens the file in chrome:

1. Go to 'Tools'

2. Hover your mouse over 'build system'. At the bottom of the list brought up, click 'New Build System...'

3. In the new build system file type this:

   {"cmd": [ "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe", "$file"]}
   

**provided the path stated above in the first set of quotes is the path to where chrome is located on your computer, if it isn't simply find the location of chrome and replace the path in the first set of quotes with the path to chrome on your computer.

Reduce the memory size to Xmx512m and it works.

OK, finally we have an answer...

You are correctly specifying headers: {"Content-Type": "application/json"}, to set your content type. Under the hood either the package http or the lower level dart:io HttpClient is changing this to application/json; charset=utf-8. However, your server web application obviously isn't expecting the suffix.

To prove this I tried it in Java, with the two versions

conn.setRequestProperty("content-type", "application/json; charset=utf-8"); // fails
conn.setRequestProperty("content-type", "application/json"); // works

Are you able to contact the web application owner to explain their bug? I can't see where Dart is adding the suffix, but I'll look later.

EDIT Later investigation shows that it's the http package that, while doing a lot of the grunt work for you, is adding the suffix that your server dislikes. If you can't get them to fix the server then you can by-pass http and use the dart:io HttpClient directly. You end up with a bit of boilerplate which is normally handled for you by http.

Working example below:

import 'dart:convert';
import 'dart:io';
import 'dart:async';

main() async {
  String url =
      'https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';
  Map map = {
    'data': {'apikey': '12345678901234567890'},
  };

  print(await apiRequest(url, map));
}

Future<String> apiRequest(String url, Map jsonMap) async {
  HttpClient httpClient = new HttpClient();
  HttpClientRequest request = await httpClient.postUrl(Uri.parse(url));
  request.headers.set('content-type', 'application/json');
  request.add(utf8.encode(json.encode(jsonMap)));
  HttpClientResponse response = await request.close();
  // todo - you should check the response.statusCode
  String reply = await response.transform(utf8.decoder).join();
  httpClient.close();
  return reply;
}

Depending on your use case, it may be more efficient to re-use the HttpClient, rather than keep creating a new one for each request. Todo - add some error handling ;-)

you could change the innerHtml on an element

function produceMessage(){
    var msg= 'Hello<br />';
     document.getElementById('someElement').innerHTML = msg;
}

the core functions are getBytes(String charset) and new String(byte[] data). you can use these functions to do UTF-8 decoding.

UTF-8 decoding actually is a string to string conversion, the intermediate buffer is a byte array. since the target is an UTF-8 string, so the only parameter for new String() is the byte array, which calling is equal to new String(bytes, "UTF-8")

Then the key is the parameter for input encoded string to get internal byte array, which you should know beforehand. If you don't, guess the most possible one, "ISO-8859-1" is a good guess for English user.

The decoding sentence should be

String decoded = new String(encoded.getBytes("ISO-8859-1"));

Create a SQLCLR assembly with external access permission that returns the list of files as a result set. There are many examples how to do this, eg. Yet another TVF: returning files from a directory or Trading in xp_cmdshell for SQLCLR (Part 1) - List Directory Contents.

Since you used the Windows installer, everything is set up for you to run MySQL 5.7 as a Windows service, which is a great option in most cases.

Instead of running mysqld.exe from the command line,

1. Win + R
2. Run services.msc
3. Right-click on MySQL57
4. Start the service.

Try this,

select to_char(sysdate,'dd') from dual; -> 08 (date)
select to_char(sysdate,'mm') from dual; -> 02 (month in number)
select to_char(sysdate,'yyyy') from dual; -> 2013 (Full year)

I just installed WAMP 3 on Windows 10 and did not have Apache in the WampServer system tray options.

But the httpd.conf file is located here:

C:\wamp64\bin\apache\apache2.4.17\conf\

In that folder, open httpd.conf with a text editor. Then go to line 62-63 and change 80 to 8080 like this:

Listen 0.0.0.0:8080
Listen [::0]:8080

Then go to the WampServer icon in the system tray and right-click > Exit, then Open WampServer again, and it should now turn green.

Now go to localhost:8080 to see your server config page.

You cannot use the VB line-continuation character inside of a string.

Moving element with respect to each other is something I needed a lot in a project of mine. So I wrote a small util class that moves an element in an list to a position relative to another element. Feel free to use (and improve upon ;))

import java.util.List;

public class ListMoveUtil
{
    enum Position
    {
        BEFORE, AFTER
    };

    /**
     * Moves element `elementToMove` to be just before or just after `targetElement`.
     *
     * @param list
     * @param elementToMove
     * @param targetElement
     * @param pos
     */
    public static <T> void moveElementTo( List<T> list, T elementToMove, T targetElement, Position pos )
    {
        if ( elementToMove.equals( targetElement ) )
        {
            return;
        }
        int srcIndex = list.indexOf( elementToMove );
        int targetIndex = list.indexOf( targetElement );
        if ( srcIndex < 0 )
        {
            throw new IllegalArgumentException( "Element: " + elementToMove + " not in the list!" );
        }
        if ( targetIndex < 0 )
        {
            throw new IllegalArgumentException( "Element: " + targetElement + " not in the list!" );
        }
        list.remove( elementToMove );

        // if the element to move is after the targetelement in the list, just remove it
        // else the element to move is before the targetelement. When we removed it, the targetindex should be decreased by one
        if ( srcIndex < targetIndex )
        {
            targetIndex -= 1;
        }
        switch ( pos )
        {
            case AFTER:
                list.add( targetIndex + 1, elementToMove );
                break;
            case BEFORE:
                list.add( targetIndex, elementToMove );
                break;
        }
    }

You can use a select into statement. See more at W3Schools.

foreach can handle arrays and objects. You can check this with:

$can_foreach = is_array($var) || is_object($var);
if ($can_foreach) {
    foreach ($var as ...
}

You don't need to specifically check for Traversable as others have hinted it in their answers, because all objects - like all arrays - are traversable in PHP.

More technically:

foreach works with all kinds of traversables, i.e. with arrays, with plain objects (where the accessible properties are traversed) and Traversable objects (or rather objects that define the internal get_iterator handler).

(source)

Simply said in common PHP programming, whenever a variable is

• an array
• an object

and is not

• NULL
• a resource
• a scalar

you can use foreach on it.

you can try this one

var obj = {
  "a": "test1",
  "b": "test2"
};

const findSpecificStr = (obj, str) => {
  return Object.values(obj).includes(str);
}

findSpecificStr(obj, 'test1');

DECLARE @chr nvarchar(50) = (SELECT CONVERT(nvarchar(50), GETDATE(), 103))

SELECT @chr chars, CONVERT(date, @chr, 103) date_again

Apart from all the other answers, what you can do is :

long l = Long.parseLong("600851475143");

for example :

obj.function(Long.parseLong("600851475143"));

If you're using MacPorts, the path is

/opt/local/share/java/gradle

The other scenario you mush verify is that the file you're trying to unpack is not empty and is valid.

In my case I wasn't downloading the file correctly, after double check and I made sure I had the right file I could unpack it without any issues.

You might want to check your matplotlib version.

Somehow I installed a dev version of matplotlib which caused the issue. A downgrade to stable release fixed it.

One can also can try python -v -c 'import YOUR_PACKAGE' 2>&1 | less to see where the issue occurred and if the lines above error can give you some hints.

In navigateExtra we can pass only some specific name as argument otherwise it showing error like below: For Ex- Here I want to pass customer key in router navigate and I pass like this-

this.Router.navigate(['componentname'],{cuskey: {customerkey:response.key}});

but it showing some error like below:

Argument of type '{ cuskey: { customerkey: any; }; }' is not assignable to parameter of type 'NavigationExtras'.
  Object literal may only specify known properties, and 'cuskey' does not exist in type 'NavigationExt## Heading ##ras'

.

Solution: we have to write like this:

this.Router.navigate(['componentname'],{state: {customerkey:response.key}});

If you are trying to read a file from the workspace during a pipeline build step, there's a method for that:

readFile('name-of-file.groovy')

For reference, see https://jenkins.io/doc/pipeline/steps/workflow-basic-steps/#readfile-read-file-from-workspace.

try it out with the following code

function fun1()  
{  
   $this->db->select('count(DISTINCT(accessid))');  
   $this->db->from('accesslog');  
   $this->db->where('record =','123');  
   $query=$this->db->get();  
   return $query->num_rows();  
}

Method 1

You should not make an ajax call, just put the src of the img element as the url of the image.

This would be useful if you use GET instead of POST

<script type="text/javascript" > 

  $(document).ready( function() { 
      $('.div_imagetranscrits').html('<img src="get_image_probes_via_ajax.pl?id_project=xxx" />')
  } );

</script>

Method 2

If you want to POST to that image and do it the way you do (trying to parse the contents of the image on the client side, you could try something like this: http://en.wikipedia.org/wiki/Data_URI_scheme

You'll need to encode the data to base64, then you could put data:[<MIME-type>][;charset=<encoding>][;base64],<data> into the img src

as example:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot img" />

To encode to base64:

• in plain javascript, see How can you encode a string to Base64 in JavaScript?
• in perl http://perldoc.perl.org/MIME/Base64.html
• in php http://php.net/manual/en/function.base64-encode.php

I am an old hand at programming and came back recently to my old passion and am struggling to fit in this Object oriented, event driven bright new world and while i see the advantages of the non sequential behavior of Javascript there are time where it really get in the way of simplicity and reusability. A simple example I have worked on was to take a photo (Mobile phone programmed in javascript, HTML, phonegap, ...), resize it and upload it on a web site. The ideal sequence is :

1. Take a photo
2. Load the photo in an img element
3. Resize the picture (Using Pixastic)
4. Upload it to a web site
5. Inform the user on success failure

All this would be a very simple sequential program if we would have each step returning control to the next one when it is finished, but in reality :

1. Take a photo is async, so the program attempt to load it in the img element before it exist
2. Load the photo is async so the resize picture start before the img is fully loaded
3. Resize is async so Upload to the web site start before the Picture is completely resized
4. Upload to the web site is asyn so the program continue before the photo is completely uploaded.

And btw 4 of the 5 steps involve callback functions.

My solution thus is to nest each step in the previous one and use .onload and other similar stratagems, It look something like this :

takeAPhoto(takeaphotocallback(photo) {
  photo.onload = function () {
    resizePhoto(photo, resizePhotoCallback(photo) {
      uploadPhoto(photo, uploadPhotoCallback(status) {
        informUserOnOutcome();
      });
    }); 
  };
  loadPhoto(photo);
});

(I hope I did not make too many mistakes bringing the code to it's essential the real thing is just too distracting)

This is I believe a perfect example where async is no good and sync is good, because contrary to Ui event handling we must have each step finish before the next is executed, but the code is a Russian doll construction, it is confusing and unreadable, the code reusability is difficult to achieve because of all the nesting it is simply difficult to bring to the inner function all the parameters needed without passing them to each container in turn or using evil global variables, and I would have loved that the result of all this code would give me a return code, but the first container will be finished well before the return code will be available.

Now to go back to Tom initial question, what would be the smart, easy to read, easy to reuse solution to what would have been a very simple program 15 years ago using let say C and a dumb electronic board ?

The requirement is in fact so simple that I have the impression that I must be missing a fundamental understanding of Javsascript and modern programming, Surely technology is meant to fuel productivity right ?.

Thanks for your patience

Raymond the Dinosaur ;-)

Unfortunately solution provided by @hakani is not two-way binding. It just handles One-way changing model from UI/FrontEnd part.

Instead the simple:

<input [(ngModel)]="checkboxFlag" type="checkbox"/>

will do two-way binding for checkbox.

Afterwards, when Model checkboxFlag is changed from Backend or UI part - voila, checkboxFlag stores actual checkbox state.

Just to complete this answer you should include the import { FormsModule } from '@angular/forms' into app.module.ts and add to imports array i.e

import { FormsModule } from '@angular/forms';

[...]

@NgModule({
  imports: [
    [...]
    FormsModule
  ],
  [...]
})

If your post try to reach the following URL

mypage.php?id=1

you will have the POST data but also GET data.

In bash version 4 associative arrays were introduced.

declare -A arr

arr["key1"]=val1

arr+=( ["key2"]=val2 ["key3"]=val3 )

The arr array now contains the three key value pairs. Bash is fairly limited what you can do with them though, no sorting or popping etc.

for key in ${!arr[@]}; do
    echo ${key} ${arr[${key}]}
done

Will loop over all key values and echo them out.

Note: Bash 4 does not come with Mac OS X because of its GPLv3 license; you have to download and install it. For more on that see here

Want to put out there that there is not much to worry about if someone provides an answer as an extension method because an extension method is just a cool way to call an instance method. I understand that you want the answer without using an extension method. Regardless if the method is defined as static, instance or extension - the result is the same.

The code below uses the code from the accepted answer to define an extension method and an instance method and creates a unit test to show the output is the same.

public static class Extensions
{
    public static void Each<T>(this IEnumerable<T> items, Action<T> action)
    {
        foreach (var item in items)
        {
            action(item);
        }
    }
}

[TestFixture]
public class ForEachTests
{
    public void Each<T>(IEnumerable<T> items, Action<T> action)
    {
        foreach (var item in items)
        {
            action(item);
        }
    }

    private string _extensionOutput;

    private void SaveExtensionOutput(string value)
    {
        _extensionOutput += value;
    }

    private string _instanceOutput;

    private void SaveInstanceOutput(string value)
    {
        _instanceOutput += value;
    }

    [Test]
    public void Test1()
    {
        string[] teams = new string[] {"cowboys", "falcons", "browns", "chargers", "rams", "seahawks", "lions", "heat", "blackhawks", "penguins", "pirates"};

        Each(teams, SaveInstanceOutput);

        teams.Each(SaveExtensionOutput);

        Assert.AreEqual(_extensionOutput, _instanceOutput);
    }
}

Quite literally, the only thing you need to do to convert an extension method to an instance method is remove the static modifier and the first parameter of the method.

This method

public static void Each<T>(this IEnumerable<T> items, Action<T> action)
{
    foreach (var item in items)
    {
        action(item);
    }
 }

becomes

public void Each<T>(Action<T> action)
{
    foreach (var item in items)
    {
        action(item);
    }
 }

the service have 4 operations: 1. GetServiceDetails 2. GetArrivalBoard 3. GetDepartureBoard 4. GetArrivalDepartureBoard

In this case you need to go up to the <tr> then use .next(), like this:

$(obj).closest('tr').next().find('.class');

Or if there may be rows in-between without the .class inside, you can use .nextAll(), like this:

$(obj).closest('tr').nextAll(':has(.class):first').find('.class');

I'm using the one used by Django and it seems to work pretty well:

def is_valid_url(url):
    import re
    regex = re.compile(
        r'^https?://'  # http:// or https://
        r'(?:(?:[A-Z0-9](?:[A-Z0-9-]{0,61}[A-Z0-9])?\.)+[A-Z]{2,6}\.?|'  # domain...
        r'localhost|'  # localhost...
        r'\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})' # ...or ip
        r'(?::\d+)?'  # optional port
        r'(?:/?|[/?]\S+)$', re.IGNORECASE)
    return url is not None and regex.search(url)

The TortoiseSVN TSVN Manual is based on subversion book, but available in a lot more languages.

In configuration class define LocalDateSerializer and LocalDateDeserializer class and register them to ObjectMapper via JavaTimeModule like below:

@Configuration
public class AppConfig
{
@Bean
    public ObjectMapper objectMapper()
    {
        ObjectMapper mapper = new ObjectMapper();
        mapper.setSerializationInclusion(Include.NON_EMPTY);
        //other mapper configs
        // Customize de-serialization


        JavaTimeModule javaTimeModule = new JavaTimeModule();
        javaTimeModule.addSerializer(LocalDate.class, new LocalDateSerializer());
        javaTimeModule.addDeserializer(LocalDate.class, new LocalDateDeserializer());
        mapper.registerModule(javaTimeModule);

        return mapper;
    }

    public class LocalDateSerializer extends JsonSerializer<LocalDate> {
        @Override
        public void serialize(LocalDate value, JsonGenerator gen, SerializerProvider serializers) throws IOException {
            gen.writeString(value.format(Constant.DATE_TIME_FORMATTER));
        }
    }

    public class LocalDateDeserializer extends JsonDeserializer<LocalDate> {

        @Override
        public LocalDate deserialize(JsonParser p, DeserializationContext ctxt) throws IOException {
            return LocalDate.parse(p.getValueAsString(), Constant.DATE_TIME_FORMATTER);
        }
    }
}

Above mentioned issue happened in my local system. Check in sql server configuration manager.
Step 1:
SQL server Network configuration
step 2:

• Protocols for local server name
• Protocol name VIA Disabled or not..
• if not disabled , disable and check

.. after I made changes the sql server browser started working

Actually, you need to call SET SERVEROUTPUT ON; before the BEGIN call.

Everyone suggested this but offers no advice where to actually place the line:

SET SERVEROUTPUT ON;

BEGIN
    FOR rec in (SELECT * FROM EMPLOYEES) LOOP
        DBMS_OUTPUT.PUT_LINE(rec.EmployeeName);
    ENDLOOP;
END;

Otherwise, you won't see any output.

var tds = document.getElementById("ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a").getElementsByTagName("td");
time = tds[0].firstChild.value;
address = tds[3].firstChild.value;

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.

That is neither a good idea in terms of peformance nor in terms of fail-safety.

Don't poach on the Connection-Pool's territory

There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:

In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.

Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.

So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.

So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.

If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).

Conclusion:

• Don't reuse connections or any ADO.NET objects at all.
• Don't make them static/shared(in VB.NET)
• Always create, open(in case of Connections), use, close and dispose them where you need them(f.e. in a method)
• use the using-statement to dispose and close(in case of Connections) implicitely

That's true not only for Connections(although most noticable). Every object implementing IDisposable should be disposed(simplest by using-statement), all the more in the System.Data.SqlClient namespace.

All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.

Edit: Here's a possible implementation of your retrievePromotion-method:

public Promotion retrievePromotion(int promotionID)
{
    Promotion promo = null;
    var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
        using (var da = new SqlDataAdapter(queryString, connection))
        {
            // you could also use a SqlDataReader instead
            // note that a DataTable does not need to be disposed since it does not implement IDisposable
            var tblPromotion = new DataTable();
            // avoid SQL-Injection
            da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
            da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
            try
            {
                connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise 
                da.Fill(tblPromotion);
                if (tblPromotion.Rows.Count != 0)
                {
                    var promoRow = tblPromotion.Rows[0];
                    promo = new Promotion()
                    {
                        promotionID    = promotionID,
                        promotionTitle = promoRow.Field<String>("PromotionTitle"),
                        promotionUrl   = promoRow.Field<String>("PromotionURL")
                    };
                }
            }
            catch (Exception ex)
            {
                // log this exception or throw it up the StackTrace
                // we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
                throw;
            }
        }
    }
    return promo;
}

Here is some weak adobe documentation on different flash 9 wmode settings.

A note of caution on wmode transparent is here in the adobe bug trac.

And new for flash 10, are two new wmodes: gpu and direct. Please refer to Adobe Knowledge Base about wmode.

Regardless of how do you index the pushbacks your vector contains 10 elements indexed from 0 (0, 1, ..., 9). So in your second loop v[j] is invalid, when j is 10.

This will fix the error:

for(int j = 9;j >= 0;--j)
{
    cout << v[j];
}

In general it's better to think about indexes as 0 based, so I suggest you change also your first loop to this:

for(int i = 0;i < 10;++i)
{
    v.push_back(i);
}

Also, to access the elements of a container, the idiomatic approach is to use iterators (in this case: a reverse iterator):

for (vector<int>::reverse_iterator i = v.rbegin(); i != v.rend(); ++i)
{
    std::cout << *i << std::endl;
}

You can add simple white space with quotes sign: {" "}

Also you can use template literals, which allow to insert, embedd expressions (code inside curly braces):

`${2 * a + b}.?!=-` // Notice this sign " ` ",its not normal quotes.

As Ennui mentioned, IE 10 supports the -ms prefixed version of Flexbox (IE 11 supports it unprefixed). The errors I can see in your code are:

• You should have display: -ms-flexbox instead of display: -ms-flex
• I think you should specify all 3 flex values, like flex: 0 1 auto to avoid ambiguity

So the final updated code is...

.flexbox form {
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flexbox;
    display: -o-flex;
    display: flex;

    /* Direction defaults to 'row', so not really necessary to specify */
    -webkit-flex-direction: row;
    -moz-flex-direction: row;
    -ms-flex-direction: row;
    -o-flex-direction: row;
    flex-direction: row;
}

.flexbox form input[type=submit] {
    width: 31px;
}

.flexbox form input[type=text] {
    width: auto;

    /* Flex should have 3 values which is shorthand for 
       <flex-grow> <flex-shrink> <flex-basis> */
    -webkit-flex: 1 1 auto;
    -moz-flex: 1 1 auto;
    -ms-flex: 1 1 auto;
    -o-flex: 1 1 auto;
    flex: 1 1 auto;

    /* I don't think you need 'display: flex' on child elements * /
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flex;
    display: -o-flex;
    display: flex;

This is a variation on pagurix's answer, but using Eclipse Mars.

Change your web.xml file to web.bak

Ignore the errors, we'll regenerate it next.

Go into project properties -> project facets and set the Dynamic Web Module version to what you need. Eclipse now allows you to save.

Now right-click on the project. Choose Java EE Tools -> Generate Deployment Descriptor Stub.

This creates a new web.xml with the required version.

Open the new web.xml and copy across the XML header and the complete web-app opening tag to your original web.bak, delete the new web.xml and rename web.bak back to web.xml.

Done.

Use insert:

In [1]: ls = [1,2,3]

In [2]: ls.insert(0, "new")

In [3]: ls
Out[3]: ['new', 1, 2, 3]

Oracle database object names maximum length is 30 bytes.

n=len(dfo)

Q1=int((n+3)/4)  
Q3=int((3*n+1)/4)  


print("Q1 position: ", Q1, "Q1 position: " ,Q3)

print("Q1 value: ", dfo[Q1], "Q1 value: ", dfo[Q3])

You can use a library like ShieldUI to do that.

It supports exporting to both XML and XLSX widely-used Excel formats.

Talking in terms of performance :

TL;DR

Use isInstance or instanceof which have similar performance. isAssignableFrom is slightly slower.

Sorted by performance:

1. isInstance
2. instanceof (+ 0.5%)
3. isAssignableFrom (+ 2.7%)

Based on a benchmark of 2000 iterations on JAVA 8 Windows x64, with 20 warmup iterations.

In theory

Using a soft like bytecode viewer we can translate each operator into bytecode.

In the context of:

package foo;

public class Benchmark
{
  public static final Object a = new A();
  public static final Object b = new B();

  ...

}

JAVA:

b instanceof A;

Bytecode:

getstatic foo/Benchmark.b:java.lang.Object
instanceof foo/A

JAVA:

A.class.isInstance(b);

Bytecode:

ldc Lfoo/A; (org.objectweb.asm.Type)
getstatic foo/Benchmark.b:java.lang.Object
invokevirtual java/lang/Class isInstance((Ljava/lang/Object;)Z);

JAVA:

A.class.isAssignableFrom(b.getClass());

Bytecode:

ldc Lfoo/A; (org.objectweb.asm.Type)
getstatic foo/Benchmark.b:java.lang.Object
invokevirtual java/lang/Object getClass(()Ljava/lang/Class;);
invokevirtual java/lang/Class isAssignableFrom((Ljava/lang/Class;)Z);

Measuring how many bytecode instructions are used by each operator, we could expect instanceof and isInstance to be faster than isAssignableFrom. However, the actual performance is NOT determined by the bytecode but by the machine code (which is platform dependent). Let's do a micro benchmark for each of the operators.

The benchmark

Credit: As advised by @aleksandr-dubinsky, and thanks to @yura for providing the base code, here is a JMH benchmark (see this tuning guide):

class A {}
class B extends A {}

public class Benchmark {

    public static final Object a = new A();
    public static final Object b = new B();

    @Benchmark
    @BenchmarkMode(Mode.Throughput)
    @OutputTimeUnit(TimeUnit.MICROSECONDS)
    public boolean testInstanceOf()
    {
        return b instanceof A;
    }

    @Benchmark
    @BenchmarkMode(Mode.Throughput)
    @OutputTimeUnit(TimeUnit.MICROSECONDS)
    public boolean testIsInstance()
    {
        return A.class.isInstance(b);
    }

    @Benchmark
    @BenchmarkMode(Mode.Throughput)
    @OutputTimeUnit(TimeUnit.MICROSECONDS)
    public boolean testIsAssignableFrom()
    {
        return A.class.isAssignableFrom(b.getClass());
    }

    public static void main(String[] args) throws RunnerException {
        Options opt = new OptionsBuilder()
                .include(TestPerf2.class.getSimpleName())
                .warmupIterations(20)
                .measurementIterations(2000)
                .forks(1)
                .build();

        new Runner(opt).run();
    }
}

Gave the following results (score is a number of operations in a time unit, so the higher the score the better):

Benchmark                       Mode   Cnt    Score   Error   Units
Benchmark.testIsInstance        thrpt  2000  373,061 ± 0,115  ops/us
Benchmark.testInstanceOf        thrpt  2000  371,047 ± 0,131  ops/us
Benchmark.testIsAssignableFrom  thrpt  2000  363,648 ± 0,289  ops/us

Warning

• the benchmark is JVM and platform dependent. Since there are no significant differences between each operation, it might be possible to get a different result (and maybe different order!) on a different JAVA version and/or platforms like Solaris, Mac or Linux.
• the benchmark compares the performance of "is B an instance of A" when "B extends A" directly. If the class hierarchy is deeper and more complex (like B extends X which extends Y which extends Z which extends A), results might be different.
• it is usually advised to write the code first picking one of the operators (the most convenient) and then profile your code to check if there are a performance bottleneck. Maybe this operator is negligible in the context of your code, or maybe...
• in relation to the previous point, instanceof in the context of your code might get optimized more easily than an isInstance for example...

To give you an example, take the following loop:

class A{}
class B extends A{}

A b = new B();

boolean execute(){
  return A.class.isAssignableFrom(b.getClass());
  // return A.class.isInstance(b);
  // return b instanceof A;
}

// Warmup the code
for (int i = 0; i < 100; ++i)
  execute();

// Time it
int count = 100000;
final long start = System.nanoTime();
for(int i=0; i<count; i++){
   execute();
}
final long elapsed = System.nanoTime() - start;

Thanks to the JIT, the code is optimized at some point and we get:

• instanceof: 6ms
• isInstance: 12ms
• isAssignableFrom : 15ms

Note

Originally this post was doing its own benchmark using a for loop in raw JAVA, which gave unreliable results as some optimization like Just In Time can eliminate the loop. So it was mostly measuring how long did the JIT compiler take to optimize the loop: see Performance test independent of the number of iterations for more details

I don't know what you want to do, but this is how I actually translated your example code....

package test;

/**
 * @author The Elite Gentleman
 *
 */
public enum Strings {
    STRING_ONE("ONE"),
    STRING_TWO("TWO")
    ;

    private final String text;

    /**
     * @param text
     */
    Strings(final String text) {
        this.text = text;
    }

    /* (non-Javadoc)
     * @see java.lang.Enum#toString()
     */
    @Override
    public String toString() {
        return text;
    }
}

Alternatively, you can create a getter method for text.

You can now do Strings.STRING_ONE.toString();

Make option defaultSelected

HTMLOptionElement.defaultSelected = true;     // JS
$('selector').prop({defaultSelected: true});  // jQuery  

HTMLOptionElement ^MDN

If the SELECT element is already added to the document (statically or dynamically), to set an option to Attribute-selected and to make it survive a HTMLFormElement.reset() - defaultSelected is used:

const EL_country = document.querySelector('#country');_x000D_
EL_country.value = 'ID';   // Set SELECT value to 'ID' ("Indonesia")_x000D_
EL_country.options[EL_country.selectedIndex].defaultSelected = true; // Add Attribute selected to Option Element_x000D_
_x000D_
document.forms[0].reset(); // "Indonesia" is still selected

<form>_x000D_
  <select name="country" id="country">_x000D_
    <option value="AF">Afghanistan</option>_x000D_
    <option value="AL">Albania</option>_x000D_
    <option value="HR">Croatia</option>_x000D_
    <option value="ID">Indonesia</option>_x000D_
    <option value="ZW">Zimbabwe</option>_x000D_
  </select>_x000D_
</form>

The above will also work if you build the options dynamically, and than (only afterwards) you want to set one option to be defaultSelected.

const countries = {_x000D_
  AF: 'Afghanistan',_x000D_
  AL: 'Albania',_x000D_
  HR: 'Croatia',_x000D_
  ID: 'Indonesia',_x000D_
  ZW: 'Zimbabwe',_x000D_
};_x000D_
_x000D_
const EL_country = document.querySelector('#country');_x000D_
_x000D_
// (Bad example. Ideally use .createDocumentFragment() and .appendChild() methods)_x000D_
EL_country.innerHTML = Object.keys(countries).reduce((str, key) => str += `<option value="${key}">${countries[key]}</option>`, ''); _x000D_
_x000D_
EL_country.value = 'ID';_x000D_
EL_country.options[EL_country.selectedIndex].defaultSelected = true;_x000D_
_x000D_
document.forms[0].reset(); // "Indonesia" is still selected

<form>_x000D_
  <select name="country" id="country"></select>_x000D_
</form>

Make option defaultSelected while dynamically creating options

To make an option selected while populating the SELECT Element, use the Option() constructor ^MDN

var optionElementReference = new Option(text, value, defaultSelected, selected);

const countries = {_x000D_
  AF: 'Afghanistan',_x000D_
  AL: 'Albania',_x000D_
  HR: 'Croatia',_x000D_
  ID: 'Indonesia',     // <<< make this one defaultSelected_x000D_
  ZW: 'Zimbabwe',_x000D_
};_x000D_
_x000D_
const EL_country = document.querySelector('#country');_x000D_
const DF_options = document.createDocumentFragment();_x000D_
_x000D_
Object.keys(countries).forEach(key => {_x000D_
  const isIndonesia = key === 'ID';  // Boolean_x000D_
  DF_options.appendChild(new Option(countries[key], key, isIndonesia, isIndonesia))_x000D_
});_x000D_
_x000D_
EL_country.appendChild(DF_options);_x000D_
_x000D_
document.forms[0].reset(); // "Indonesia" is still selected

<form>_x000D_
  <select name="country" id="country"></select>_x000D_
</form>

In the demo above Document.createDocumentFragment is used to prevent rendering elements inside the DOM in a loop. Instead, the fragment (containing all the Options) is appended to the Select only once.

SELECT.value vs. OPTION.setAttribute vs. OPTION.selected vs. OPTION.defaultSelected

Although some (older) browsers interpret the OPTION's selected attribute as a "string" state, the WHATWG HTML Specifications ^{html.spec.whatwg.org} state that it should represent a Boolean selectedness

The selectedness of an option element is a boolean state, initially false. Except where otherwise specified, when the element is created, its selectedness must be set to true if the element has a selected attribute.
^{html.spec.whatwg.org - Option selectedness}

one can correctly deduce that just the name selected in <option value="foo" selected> is enough to set a truthy state.

Although the test 2. using .setAttribute() seems at first the best solution since both the Element Property and Attribute are unison, it can lead to confusion, specially because .setAttribute expects two parameters:

EL_select.options[1].setAttribute('selected', false);
// <option value="AL" selected="false"> // But still selected!

will actually make the option selected

Should one use .removeAttribute() or perhaps .setAttribute('selected', ???) to another value? Or should one read the state by using .getAttribute('selected') or by using .hasAttribute('selected')?

Instead test 3. (and 4.) using defaultSelected gives the expected results:

• Attribute selected as a named Selectedness state.
• Property selected on the Element Object, with a Boolean value.

To add interceptor to a spring boot application, do the following

1. Create an interceptor class

   public class MyCustomInterceptor implements HandlerInterceptor{
   
       //unimplemented methods comes here. Define the following method so that it     
       //will handle the request before it is passed to the controller.
   
       @Override
       public boolean preHandle(HttpServletRequest request,HttpServletResponse  response){
       //your custom logic here.
           return true;
       }
   }
   

2. Define a configuration class

   @Configuration
   public class MyConfig extends WebMvcConfigurerAdapter{
       @Override
       public void addInterceptors(InterceptorRegistry registry){
           registry.addInterceptor(new MyCustomInterceptor()).addPathPatterns("/**");
       }
   }
   

3. Thats it. Now all your requests will pass through the logic defined under preHandle() method of MyCustomInterceptor.

1. Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler, which defines a method that is invoked when a proxy method is invoked.

2. You create them by using the call

   Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
   

   The arguments are:

   1. classLoader. Once the class is generated, it is loaded with this class loader.
   2. interfaces. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.
   3. invocationHandler. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler. When a method from any of the supported interfaces, or hashCode, equals, or toString, is invoked, the method invoke is invoked on the handler, passing the Method object for the method to be invoked and the arguments passed.

   For more on this, see the documentation for the Proxy class.

3. Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.

Along with the already suggested methods of using a foreach loop, I thought I'd also mention that any object that implements IEnumerable also provides an IEnumerator interface via the GetEnumerator method. Although this method is usually not necessary, this can be used for manually iterating over collections, and is particularly useful when writing your own extension methods for collections.

IEnumerable<T> mySequence;
using (var sequenceEnum = mySequence.GetEnumerator())
{
    while (sequenceEnum.MoveNext())
    {
        // Do something with sequenceEnum.Current.
    }
}

A prime example is when you want to iterate over two sequences concurrently, which is not possible with a foreach loop.

ES6 version:

const angleInRadians = angleInDegrees => (angleInDegrees - 90) * (Math.PI / 180.0);

const polarToCartesian = (centerX, centerY, radius, angleInDegrees) => {
    const a = angleInRadians(angleInDegrees);
    return {
        x: centerX + (radius * Math.cos(a)),
        y: centerY + (radius * Math.sin(a)),
    };
};

const arc = (x, y, radius, startAngle, endAngle) => {
    const fullCircle = endAngle - startAngle === 360;
    const start = polarToCartesian(x, y, radius, endAngle - 0.01);
    const end = polarToCartesian(x, y, radius, startAngle);
    const arcSweep = endAngle - startAngle <= 180 ? '0' : '1';

    const d = [
        'M', start.x, start.y,
        'A', radius, radius, 0, arcSweep, 0, end.x, end.y,
    ].join(' ');

    if (fullCircle) d.push('z');
    return d;
};

Use the _ variable, as I learned when I asked this question, for example:

# A long way to do integer exponentiation
num = 2
power = 3
product = 1
for _ in xrange(power):
    product *= num
print product

I would have your main thread pass a callback method to your first thread, and when it's done, it will invoke the callback method on the mainthread, which can launch the second thread. This keeps your main thread from hanging while its waiting for a Join or Waithandle. Passing methods as delegates is a useful thing to learn with C# anyway.

Here is a solution with shell parameter expansion that replaces multiple contiguous occurrences with a single _:

$ var=AxxBCyyyDEFzzLMN
$ echo "${var//+([xyz])/_}"
A_BC_DEF_LMN

Notice that the +(pattern) pattern requires extended pattern matching, turned on with

shopt -s extglob

Alternatively, with the -s ("squeeze") option of tr:

$ tr -s xyz _ <<< "$var"
A_BC_DEF_LMN

To add to what blxtd answered above, bus errors also occur when your process cannot attempt to access the memory of a particular 'variable'.

for (j = 0; i < n; j++) {
    for (i =0; i < m; i++) {
        a[n+1][j] += a[i][j];
    }
}

Notice the 'inadvertent' usage of variable 'i' in the first 'for loop'? That's what is causing the bus error in this case.

SELECT MAX(ID) from bugs WHERE user=Me

System.getenv("SECONDARY_STORAGE") returns null for Marshmallow. This is another way of finding all the externals dirs. You can check if it's removable which determines if internal/external

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    File[] externalCacheDirs = context.getExternalCacheDirs();
    for (File file : externalCacheDirs) {
        if (Environment.isExternalStorageRemovable(file)) {
            // It's a removable storage
        }
    }
}

There's also

int[] array = {-1, -1, -1, -1, -1, -1, -1, -1, -1, -1};

If you are using API 2.0 or newer this will work.

int id = **"The Video's ID"**
ImageView iv = (ImageView ) convertView.findViewById(R.id.imagePreview);
ContentResolver crThumb = getContentResolver();
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(crThumb, id, MediaStore.Video.Thumbnails.MICRO_KIND, options);
iv.setImageBitmap(curThumb);

Wildcard works for me also, but I'd like to give a side note for those using directory variables. Always use slash for folder tree (not backslash), otherwise it will fail:

BASEDIR = ../..
SRCDIR = $(BASEDIR)/src
INSTALLDIR = $(BASEDIR)/lib

MODULES = $(wildcard $(SRCDIR)/*.cpp)
OBJS = $(wildcard *.o)

A Scala version based on Zaz's answer.

  case class DocumentEx(document: Document) {
    def toXmlString(pretty: Boolean = false):Try[String] = {
      getStringFromDocument(document, pretty)
    }
  }

  implicit def documentToDocumentEx(document: Document):DocumentEx = {
    DocumentEx(document)
  }

  def getStringFromDocument(doc: Document, pretty:Boolean): Try[String] = {
    try
    {
      val domSource= new DOMSource(doc)
      val writer = new StringWriter()
      val result = new StreamResult(writer)
      val tf = TransformerFactory.newInstance()
      val transformer = tf.newTransformer()
      if (pretty)
        transformer.setOutputProperty(OutputKeys.INDENT, "yes")
      transformer.transform(domSource, result)
      Success(writer.toString);
    }
    catch {
      case ex: TransformerException =>
        Failure(ex)
    }
  }

With that, you can do either doc.toXmlString() or call the getStringFromDocument(doc) function.

You need to use this line of code to resolve your problem:

__block Person *aPerson = nil;

Just use the cached flag if you added, but haven't committed yet:

git diff --cached --color

Another tricky thing with modern Android is you set the device behavior by selecting "Use for" of the device.

If it is set as "Use for" charging for example the device won't be detected by ADB. switching to PTP/MTP other behavior which is more 'active' will auto-magically make your device detectable.

a.button:hover{
    background: #383;  }

works for me but in my case

#buttonClick:hover {
background-color:green;  }

If you don't want any changes in design and definitely want it to just match a remote's branch, you can also just delete the branch and recreate it:

# Switch to some branch other than design
$ git br -D design
$ git co -b design origin/design            # Will set up design to track origin's design branch

If all you are looking for is killing a package

pkill package_name 

should work

You can use System.currentTimeMillis().

At least in OpenJDK, Date uses this under the covers.

The call in System is to a native JVM method, so we can't say for sure there's no allocation happening under the covers, though it seems unlikely here.

Here's a correction to Mehdiway's answer. The new width and/or height were not being set to the max value. A good test case is the following (1768 x 1075 pixels): http://spacecoastsports.com/wp-content/uploads/2014/06/sportsballs1.png. (I wasn't able to comment on it above due to lack of reputation points.)

  // Make sure image doesn't exceed 100x100 pixels
  // note: takes jQuery img object not HTML: so width is a function
  // not a property.
  function resize_image (image) {
      var maxWidth = 100;           // Max width for the image
      var maxHeight = 100;          // Max height for the image
      var ratio = 0;                // Used for aspect ratio

      // Get current dimensions
      var width = image.width()
      var height = image.height(); 
      console.log("dimensions: " + width + "x" + height);

      // If the current width is larger than the max, scale height
      // to ratio of max width to current and then set width to max.
      if (width > maxWidth) {
          console.log("Shrinking width (and scaling height)")
          ratio = maxWidth / width;
          height = height * ratio;
          width = maxWidth;
          image.css("width", width);
          image.css("height", height);
          console.log("new dimensions: " + width + "x" + height);
      }

      // If the current height is larger than the max, scale width
      // to ratio of max height to current and then set height to max.
      if (height > maxHeight) {
          console.log("Shrinking height (and scaling width)")
          ratio = maxHeight / height;
          width = width * ratio;
          height = maxHeight;
          image.css("width", width);
          image.css("height", height);
          console.log("new dimensions: " + width + "x" + height);
      }
  }

I think I am late in answering this question, but it keep coming up in my feed.

Navneet has provided excellent answer. Adding to it visually.

Partitioning helps in elimination of data, if used in WHERE clause, where as bucketing helps in organizing data in each partition into multiple files, so as same set of data is always written in same bucket. Helps a lot in joining of columns.

Suppose, you have a table with five columns, name, server_date, some_col3, some_col4 and some_col5. Suppose, you have partitioned the table on server_date and bucketed on name column in 10 buckets, your file structure will look something like below.

1. server_date=xyz
   • 00000_0
   • 00001_0
   • 00002_0
   • ........
   • 00010_0

Here server_date=xyz is the partition and 000 files are the buckets in each partition. Buckets are calculated based on some hash functions, so rows with name=Sandy will always go in same bucket.

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

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

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

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

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

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

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

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

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

You can manually set xticks (and yticks) using pyplot.xticks:

import matplotlib.pyplot as plt
import numpy as np

x = np.array([0,1,2,3])
y = np.array([20,21,22,23])
my_xticks = ['John','Arnold','Mavis','Matt']
plt.xticks(x, my_xticks)
plt.plot(x, y)
plt.show()

Beside GitStats (git history statistics generator) mentioned by xyld, written in Python and requiring Gnuplot for graphs, there is also

• gitstat (SourceForge) project (web-based git statistics interface), written in PHP and Perl,
• Git Statistics, aka gitstats (metrics framework designed to gather statistics on git repositories), written in Python, result of git-statistics project at Google Summer of Code 2008 This is not a web app
• gitinspector Is a rather new, CLI based Python tool for generating nice reports
• Hercules - native app without dependencies, written in Go, which specializes in advanced analysis types.

Here is an alternate way to make the installer and get rid of that error message. Also it seems that VS2015 express does not have the "Add Installer" menu item.

You simply need to create a class and add the below code and add the reference System.Configuration.Install.dll.

using System.Configuration.Install;
using System.ServiceProcess;
using System.ComponentModel;


namespace SAS
{
    [RunInstaller(true)]
    public class MyProjectInstaller : Installer
    {
        private ServiceInstaller serviceInstaller1;
        private ServiceProcessInstaller processInstaller;

        public MyProjectInstaller()
        {
            // Instantiate installer for process and service.
            processInstaller = new ServiceProcessInstaller();
            serviceInstaller1 = new ServiceInstaller();

            // The service runs under the system account.
            processInstaller.Account = ServiceAccount.LocalSystem;

            // The service is started manually.
            serviceInstaller1.StartType = ServiceStartMode.Manual;

            // ServiceName must equal those on ServiceBase derived classes.
            serviceInstaller1.ServiceName = "SAS Service";

            // Add installer to collection. Order is not important if more than one service.
            Installers.Add(serviceInstaller1);
            Installers.Add(processInstaller);
        }
    }
}

No, there is no built-in support for building strings. You have to use concatenation instead.

You can, of course, make an array of different parts of your string and then call join() on that array, but it then depends on how the join is implemented in the JavaScript interpreter you are using.

I made an experiment to compare the speed of str1+str2 method versus array.push(str1, str2).join() method. The code was simple:

var iIterations =800000;
var d1 = (new Date()).valueOf();
str1 = "";
for (var i = 0; i<iIterations; i++)
    str1 = str1 + Math.random().toString();
var d2 = (new Date()).valueOf();
log("Time (strings): " + (d2-d1));

var d3 = (new Date()).valueOf();
arr1 = [];
for (var i = 0; i<iIterations; i++)
    arr1.push(Math.random().toString());
var str2 = arr1.join("");
var d4 = (new Date()).valueOf();
log("Time (arrays): " + (d4-d3));

I tested it in Internet Explorer 8 and Firefox 3.5.5, both on a Windows 7 x64.

In the beginning I tested on small number of iterations (some hundred, some thousand items). The results were unpredictable (sometimes string concatenation took 0 milliseconds, sometimes it took 16 milliseconds, the same for array joining).

When I increased the count to 50,000, the results were different in different browsers - in Internet Explorer the string concatenation was faster (94 milliseconds) and join was slower(125 milliseconds), while in Firefox the array join was faster (113 milliseconds) than string joining (117 milliseconds).

Then I increased the count to 500'000. Now the array.join() was slower than string concatenation in both browsers: string concatenation was 937 ms in Internet Explorer, 1155 ms in Firefox, array join 1265 in Internet Explorer, and 1207 ms in Firefox.

The maximum iteration count I could test in Internet Explorer without having "the script is taking too long to execute" was 850,000. Then Internet Explorer was 1593 for string concatenation and 2046 for array join, and Firefox had 2101 for string concatenation and 2249 for array join.

Results - if the number of iterations is small, you can try to use array.join(), as it might be faster in Firefox. When the number increases, the string1+string2 method is faster.

UPDATE

I performed the test on Internet Explorer 6 (Windows XP). The process stopped to respond immediately and never ended, if I tried the test on more than 100,000 iterations. On 40,000 iterations the results were

Time (strings): 59175 ms
Time (arrays): 220 ms

This means - if you need to support Internet Explorer 6, choose array.join() which is way faster than string concatenation.

This method will create the folder if it does not exist and do nothing if it exists:

Directory.CreateDirectory(path);

Addressing the first question, if you need to take several rows grouped by certain criteria with the other column with max value you can do something like this:

var query =
    from u1 in table
    join u2 in (
        from u in table
        group u by u.GroupId into g
        select new { GroupId = g.Key, MaxStatus = g.Max(x => x.Status) }
    ) on new { u1.GroupId, u1.Status } equals new { u2.GroupId, Status = u2.MaxStatus}
    select u1;

Like this: .

The . means any character except newline (which sometimes is but often isn't included, check your regex flavour).

You can rewrite your expression as ^.{1,35}$, which should match any line of length 1-35.

if any( [ i>'z' or i<'a' for i in raw_input]):
    print "Error: Contains illegal characters"
elif len(raw_input)>15:
    print "Very long string"

This method also does not assume that the object in the Session variable is a string

if((Session["MySessionVariable"] ?? "").ToString() != "")
    //More code for the Code God

So basically replaces the null variable with an empty string before converting it to a string since ToString is part of the Object class

Look at this example:

We have 2 regexps A and B and we want to match both of them, so in pseudo-code it looks like this:

pattern = "/A AND B/"

It can be written without using the AND operator like this:

pattern = "/NOT (NOT A OR NOT B)/"

in PCRE:

"/(^(^A|^B))/"

regexp_match(pattern,data)

When you are using AspectJ in your project, it may happen that some aspect hides its portion of the stack trace. For example, today I had:

java.lang.NullPointerException:
  at com.company.product.MyTest.test(MyTest.java:37)

This stack trace was printed when running the test via Maven's surefire.

On the other hand, when running the test in IntelliJ, a different stack trace was printed:

java.lang.NullPointerException
  at com.company.product.library.ArgumentChecker.nonNull(ArgumentChecker.java:67)
  at ...
  at com.company.product.aspects.CheckArgumentsAspect.wrap(CheckArgumentsAspect.java:82)
  at ...
  at com.company.product.MyTest.test(MyTest.java:37)

Remove or comment out the line-

$mail->IsSMTP();

And it will work for you.

I have checked and experimented many answers from different sites but haven't got any solution except the above solution.

I also ran into the similar issue and was using CNTLM for proxy configuration. In my case HTTP_PROXY and HTTPS_PROXY are taking higher precedence over http_proxy and https_proxy so be aware of changing all proxy variables.

env|grep -i proxy

and make sure all of the below proxy variables should point to the same proxy.

HTTP-PROXY = "http://localhost:3128"
HTTPS-PROXY = "https://localhost:3128"
HTTPS_PROXY = "http://localhost:3128"
HTTP_PROXY = "http://localhost:3128"
PROXY = "http://localhost:3128"
http-proxy = "http://localhost:3128"
http_proxy = "http://localhost:3128"
https-proxy = "https://localhost:3128/"
https_proxy = "https://localhost:3128"
proxy = "http://localhost:3128/"

I know some variables are unneccessary but I'm not sure which is using what.

IMPORTANT - on ubuntu package docker is something entirely different ( avoid it ) :

issue following to view what if any packages you have mentioning docker

dpkg -l|grep docker

if only match is following then you do NOT have docker installed below is an unrelated package

docker - System tray for KDE3/GNOME2 docklet applications

if you see something similar to following then you have docker installed

 dpkg -l|grep docker

NOTE - ubuntu package docker.io is not getting updates ( obsolete do NOT use )

Instead do this : install the latest version of docker on linux by executing the following:

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker stens

Remember that you will have to log out and back in for this to take effect!

Here is the underlying detailed install instructions which as you can see comes bundled into above technique ... Above one liner gives you same as :

https://docs.docker.com/engine/installation/linux/ubuntulinux/

Once installed you can see what docker packages were installed by issuing

dpkg -l|grep docker
ii  docker-ce                                  5:19.03.13~3-0~ubuntu-focal         amd64        Docker: the open-source application container engine
ii  docker-ce-cli                              5:19.03.13~3-0~ubuntu-focal         amd64        Docker CLI: the open-source application container engine

now Docker updates will get installed going forward when you issue

sudo apt-get update
sudo apt-get upgrade

take a look at

 ls -latr /etc/apt/sources.list.d/*docker*
-rw-r--r-- 1 root root 202 Jun 23 10:01 /etc/apt/sources.list.d/docker.list.save
-rw-r--r-- 1 root root  71 Jul  4 11:32 /etc/apt/sources.list.d/docker.list


cat /etc/apt/sources.list.d/docker.list

deb [arch=amd64] https://apt.dockerproject.org/repo ubuntu-xenial main

or more generally

cd /etc/apt
grep -r docker *
sources.list.d/docker.list:deb [arch=amd64] https://download.docker.com/linux/ubuntu focal test

If you're using maven I would do something like this:

Being production your default profile:

<properties>
    <activeProfile>production</activeProfile>
</properties>

And as an example of other profiles:

<profiles>
    <!--Your default profile... selected if none specified-->
    <profile>
        <id>production</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <activeProfile>production</activeProfile>
        </properties>
    </profile>

    <!--Profile 2-->
    <profile>
        <id>development</id>
        <properties>
            <activeProfile>development</activeProfile>
        </properties>
    </profile>

    <!--Profile 3-->
    <profile>
        <id>otherprofile</id>
        <properties>
            <activeProfile>otherprofile</activeProfile>
        </properties>
    </profile>
<profiles>

In your application.properties you'll have to set:

spring.profiles.active=@activeProfile@

This works for me every time, hope it solves your problem.

No. They did not include that in ECMAScript:

ECMAScript has no goto statement.

I noticed that you can also get errors if you don't specify the angles correctly, even when using glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z)) you still might run into problems. The fix I found for this was specifying the type as glm::rotate(Model, (glm::mediump_float)90, glm::vec3(x, y, z)) instead of just saying glm::rotate(Model, 90, glm::vec3(x, y, z))

Or just write the second argument, the angle in radians (previously in degrees), as a float with no cast needed such as in:

glm::mat4 rotationMatrix = glm::rotate(glm::mat4(1.0f), 3.14f, glm::vec3(1.0));

You can add glm::radians() if you want to keep using degrees. And add the includes:

#include "glm/glm.hpp"
#include "glm/gtc/matrix_transform.hpp"

You can read the script line per line with a BufferedReader and append every line to a StringBuilder so that the script becomes one large string.

Then you can create a Statement object using JDBC and call statement.execute(stringBuilder.toString()).

You can use sheet.addMergedRegion(rowFrom,rowTo,colFrom,colTo);

example sheet.addMergedRegion(new CellRangeAddress(1,1,1,4)); will merge from B2 to E2. Remember it is zero based indexing (ex. POI version 3.12).

Assuming my-app is a subdirectory under the current directory. The $LASTEXITCODE should be there from the last command:

.\my-app\my-fle.bat

If it was from a fileshare:

\\server\my-file.bat

Try one of those three solution. It must work :) :

1. sudo apt-get install zlib1g-dev
2. sudo apt-get install libz-dev
3. sudo apt-get install lib32z1-dev

In fact what is missing is not the lz command, but the development files for the zlib library.So you should install zlib1g-devlib for ex to get it.

For rhel7 like systems the package is zlib-devel

Your html is not updated every 15 seconds. The cause could be browser caching. Add Math.random() to avoid browser caching, and it's better to wait until the DOM is fully loaded as pointed out by @shadow. But I think the main cause is the caching

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js" />
<script type="text/javascript">
$(document).ready(function(){
    var auto_refresh = setInterval(
    function ()
    {
       $('.View').load('Small.php?' + Math.random()).fadeIn("slow");
    }, 15000); // refresh every 15000 milliseconds
});
</script>

You can find the headers option in the Network tab in Developer's console in Chrome:

1. In Chrome press F12 to open Developer's console.
2. Select the Network tab. This tab gives you the information about the requests fired from the browser.
3. Select a request by clicking on the request name. There you can find the Header information for that request along with some other information like Preview, Response and Timing.

Also, in my version of Chrome (50.0.2661.102), it gives an extension named LIVE HTTP Headers which gives information about the request headers for all the HTTP requests.

update: added image

See mozilla.org's write-up on how CORS works.

You'll need your server to send back the proper response headers, something like:

Access-Control-Allow-Origin: http://foo.example
Access-Control-Allow-Methods: POST, PUT, GET, OPTIONS
Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization

Bear in mind you can use "*" for Access-Control-Allow-Origin that will only work if you're trying to pass Authentication data. In that case, you need to explicitly list the origin domains you want to allow. To allow multiple domains, see this post

String[] elements = { "a", "a", "a", "a" };

for( int i = 0; i < elements.length - 1; i++)
{
    String element = elements[i];
    String nextElement = elements[i+1];
}

Note that in this case, elements.length is 4, so you want to iterate from [0,2] to get elements 0,1, 1,2 and 2,3.

As a supplement of the answer of Michael Parker, you can make getData accept a callback function to active the setState update the data:

componentWillMount : function () {
    var data = this.getData(()=>this.setState({data : data}));
},

If you want help debugging a problem like this you need to provide the make rule or at least the tar command you invoked. How can we see what's wrong with the command if there's no command to see?

However, 99% of the time an error like this means that you're creating the tar file inside a directory that you're trying to put into the tar file. So, when tar tries to read the directory it finds the tar file as a member of the directory, starts to read it and write it out to the tar file, and so between the time it starts to read the tar file and when it finishes reading the tar file, the tar file has changed.

So for example something like:

tar cf ./foo.tar .

There's no way to "stop" this, because it's not wrong. Just put your tar file somewhere else when you create it, or find another way (using --exclude or whatever) to omit the tar file.

While performance is an issue, I think modern database designs have made it much less of an issue for small files.

Performance aside, it also depends on just how tightly-coupled the data is. If the file contains data that is closely related to the fields of the database, then it conceptually belongs close to it and may be stored in a blob. If it contains information which could potentially relate to multiple records or may have some use outside of the context of the database, then it belongs outside. For example, an image on a web page is fetched on a separate request from the page that links to it, so it may belong outside (depending on the specific design and security considerations).

Our compromise, and I don't promise it's the best, has been to store smallish XML files in the database but images and other files outside it.

Are you interested in counting the executable lines rather than the total file line count? If so you could try a code coverage tool such as EclEmma. As a side effect of the code coverage stats you get stats on the number of executable lines and blocks (and methods and classes). These are rolled up from the method level upwards, so you can see line counts for the packages, source roots and projects as well.

You should create an installer, as mentioned before. Even though it is also possible to let py2exe bundle everything into a single executable, by setting bundle_files option to 1 and the zipfile keyword argument to None, I don't recommend this for PyGTK applications.

That's because of GTK+ tries to load its data files (locals, themes, etc.) from the directory it was loaded from. So you have to make sure that the directory of your executable contains also the libraries used by GTK+ and the directories lib, share and etc from your installation of GTK+. Otherwise you will get problems running your application on a machine where GTK+ is not installed system-wide.

For more details read my guide to py2exe for PyGTK applications. It also explains how to bundle everything, but GTK+.

You are casting ClientID to char* causing the function to assume its a null terinated char array, which it is not.

from cplusplus.com :

string& append ( const char * s ); Appends a copy of the string formed by the null-terminated character sequence (C string) pointed by s. The length of this character sequence is determined by the first ocurrence of a null character (as determined by traits.length(s)).
