Just add this line:

getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);

Before your setContentView() method.

Transmission Delay:

This is the amount of time required to transmit all of the packet's bits into the link. Transmission delays are typically on the order of microseconds or less in practice. 

L: packet length (bits)
R: link bandwidth (bps)
so transmission delay is = L/R

Propagation Delay:

Is the time it takes a bit to propagate over the transmission medium from the source router to the destination router; it is a function of the distance between the two routers, but has nothing to do with the packet's length or the transmission rate of the link. 

d: length of physical link
S: propagation speed in medium (~2x10⁸m/sec, for copper wires & ~3x10⁸m/sec, for wireless media)
so propagation delay is = d/s

JavaDoc:

The maximum queue length for incoming connection indications (a request to connect) is set to 50. If a connection indication arrives when the queue is full, the connection is refused.

You should increase "backlog" parameter of your ServerSocket, for example

int backlogSize = 50 ;
new ServerSocket(port, backlogSize);

It's just a variable name, and it's conventional in python to use _ for throwaway variables. It just indicates that the loop variable isn't actually used.

For me, adding the following block of code under <dependency management><dependencies> solved the problem.

I would like to add one very important comment: -

• "In a corporate, intra- net setting," most if not all of the foregoing might not apply!

Many corporations deploy "internal use only" websites which are, effectively, "corporate applications" that happen to have been implemented through URLs. These URLs can (supposedly ...) only be resolved within "the company's internal network." (Which network magically includes all VPN-connected 'road warriors.')

When a user is dutifully-connected to the aforesaid network, their identity ("authentication") is [already ...] "conclusively known," as is their permission ("authorization") to do certain things ... such as ... "to access this website."

This "authentication + authorization" service can be provided by several different technologies, such as LDAP (Microsoft OpenDirectory), or Kerberos.

From your point-of-view, you simply know this: that anyone who legitimately winds-up at your website must be accompanied by [an environment-variable magically containing ...] a "token." (i.e. The absence of such a token must be immediate grounds for 404 Not Found.)

The token's value makes no sense to you, but, should the need arise, "appropriate means exist" by which your website can "[authoritatively] ask someone who knows (LDAP... etc.)" about any and every(!) question that you may have. In other words, you do not avail yourself of any "home-grown logic." Instead, you inquire of The Authority and implicitly trust its verdict.

Uh huh ... it's quite a mental-switch from the "wild-and-wooly Internet."

Search for "php version" at the bottom of the cpanel

Select PHP Version -> Switch to Php Options -> Change the Value -> save.

A few people have an example using setAttribute which I like. However it assumes you don't have any styles currently set. I would maybe do something like:

nFilter.setAttribute('style', nFilter.getAttribute('style') + ';width:330px;float:left;');

Or make it into a helper function like this:

function setStyle(el, css){
  el.setAttribute('style', el.getAttribute('style') + ';' + css);
}

setStyle(nFilter, 'width:330px;float:left;');

This makes sure that you can add styles to it continuously and it won't remove any style currently set by always appending to the current styles. It also adds an extra semi colon so that if there is a style ever missing one it will append another to make sure it is fully delimited.

    fmt.Printf("key[%s] value[%s]\n", k, v)

or

    fmt.Printf("key[%s] value[%s]\n", k, m[k])
}

Go language specs for for statements specifies that the first value is the key, the second variable is the value, but doesn't have to be present.

You say your website is in http://localhost/mywebsite, and let's say that your image is inside a subfolder named pictures/:

Absolute path

If you use an absolute path, / would point to the root of the site, not the root of the document: localhost in your case. That's why you need to specify your document's folder in order to access the pictures folder:

"/mywebsite/pictures/picture.png"

And it would be the same as:

"http://localhost/mywebsite/pictures/picture.png"

Relative path

A relative path is always relative to the root of the document, so if your html is at the same level of the directory, you'd need to start the path directly with your picture's directory name:

"pictures/picture.png"

But there are other perks with relative paths:

dot-slash (./)

Dot (.) points to the same directory and the slash (/) gives access to it:

So this:

"pictures/picture.png"

Would be the same as this:

"./pictures/picture.png"

Double-dot-slash (../)

In this case, a double dot (..) points to the upper directory and likewise, the slash (/) gives you access to it. So if you wanted to access a picture that is on a directory one level above of the current directory your document is, your URL would look like this:

"../picture.png"

You can play around with them as much as you want, a little example would be this:

Let's say you're on directory A, and you want to access directory X.

- root
   |- a
      |- A
   |- b
   |- x
      |- X

Your URL would look either:

Absolute path

"/x/X/picture.png"

Or:

Relative path

"./../x/X/picture.png"

\z mytable from psql gives you all the grants from a table, but you'd then have to split it up by individual user.

Instead of a Button, you can use a TextView and add a click listener in the java code.

I.e.

in the activity layout xml:

<TextView
    android:id="@+id/btn_text_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/colorPrimaryDark"
    android:text="@string/btn_text"
    android:gravity="center"
    android:textColor="@color/colorAccent"
    android:fontFamily="sans-serif-medium"
    android:textAllCaps="true" />

in the activity java file:

TextView btnTextView = (TextView) findViewById(R.id.btn_text_view);
btnTextView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // handler code
            }
        });

Some fixes I've used for this problem:

1. Check if the connection you want to share is shareable.

   a. Press Win-key + r and run ncpa.cpl

   b. Right click on the connection you want to share and go to properties

   c. Go to sharing tab and check if sharing is enabled

2. Run devmgmt.msc from the run console.

   a. Expand the network adapters list

   b. Right click -> properties on the adapter of the connection you want to share

   c. Go to power management tab and enable allow this computer to turn off this device to save power. Restart your laptop if you've made changes.

3. Check if airplane mode is disabled. You can enable airplane mode and then turn on the wi-fi, you can never know. Do disable airplane mode if it is on.

4. Use admin command prompt to run this command.

By default, Elasticsearch installed goes into read-only mode when you have less than 5% of free disk space. If you see errors similar to this:

Elasticsearch::Transport::Transport::Errors::Forbidden: [403] {"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}

Or in /usr/local/var/log/elasticsearch.log you can see logs similar to:

flood stage disk watermark [95%] exceeded on [nCxquc7PTxKvs6hLkfonvg][nCxquc7][/usr/local/var/lib/elasticsearch/nodes/0] free: 15.3gb[4.1%], all indices on this node will be marked read-only

Then you can fix it by running the following commands:

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

You have to use this code:

<android.support.v7.widget.AppCompatRadioButton
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="Radiobutton1"
                    app:buttonTint="@color/black" />

Using app:buttonTint instead of android:buttonTint and also android.support.v7.widget.AppCompatRadioButton instead of Radiobutton!

The platform is not specified, but in C# (.NET) it would be:

Regular expression (presumes the multiline option - the example below uses it):

    [ \t]+(\r?$)

Replacement:

    $1

For an explanation of "\r?$", see Regular Expression Options, Multiline Mode (MSDN).

Code example

This will remove all trailing spaces and all trailing TABs in all lines:

string inputText = "     Hello, World!  \r\n" +
                   "  Some other line\r\n" +
                   "     The last line  ";
string cleanedUpText = Regex.Replace(inputText,
                                     @"[ \t]+(\r?$)", @"$1",
                                     RegexOptions.Multiline);

Java implicitly assumes a reference to the current object for methods called like this. So

// Test2.java
public class Test2 {
    public void testMethod() {
        testMethod2();
    }

    // ...
}

Is exactly the same as

// Test2.java
public class Test2 {
    public void testMethod() {
        this.testMethod2();
    }

    // ...
}

I prefer the second version to make more clear what you want to do.

This does what you want, and will work in nearly all cases:

>>> all(x in ['b', 'a', 'foo', 'bar'] for x in ['a', 'b'])
True

The expression 'a','b' in ['b', 'a', 'foo', 'bar'] doesn't work as expected because Python interprets it as a tuple:

>>> 'a', 'b'
('a', 'b')
>>> 'a', 5 + 2
('a', 7)
>>> 'a', 'x' in 'xerxes'
('a', True)

Other Options

There are other ways to execute this test, but they won't work for as many different kinds of inputs. As Kabie points out, you can solve this problem using sets...

>>> set(['a', 'b']).issubset(set(['a', 'b', 'foo', 'bar']))
True
>>> {'a', 'b'} <= {'a', 'b', 'foo', 'bar'}
True

...sometimes:

>>> {'a', ['b']} <= {'a', ['b'], 'foo', 'bar'}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

Sets can only be created with hashable elements. But the generator expression all(x in container for x in items) can handle almost any container type. The only requirement is that container be re-iterable (i.e. not a generator). items can be any iterable at all.

>>> container = [['b'], 'a', 'foo', 'bar']
>>> items = (i for i in ('a', ['b']))
>>> all(x in [['b'], 'a', 'foo', 'bar'] for x in items)
True

Speed Tests

In many cases, the subset test will be faster than all, but the difference isn't shocking -- except when the question is irrelevant because sets aren't an option. Converting lists to sets just for the purpose of a test like this won't always be worth the trouble. And converting generators to sets can sometimes be incredibly wasteful, slowing programs down by many orders of magnitude.

Here are a few benchmarks for illustration. The biggest difference comes when both container and items are relatively small. In that case, the subset approach is about an order of magnitude faster:

>>> smallset = set(range(10))
>>> smallsubset = set(range(5))
>>> %timeit smallset >= smallsubset
110 ns ± 0.702 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)
>>> %timeit all(x in smallset for x in smallsubset)
951 ns ± 11.5 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

This looks like a big difference. But as long as container is a set, all is still perfectly usable at vastly larger scales:

>>> bigset = set(range(100000))
>>> bigsubset = set(range(50000))
>>> %timeit bigset >= bigsubset
1.14 ms ± 13.9 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
>>> %timeit all(x in bigset for x in bigsubset)
5.96 ms ± 37 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Using subset testing is still faster, but only by about 5x at this scale. The speed boost is due to Python's fast c-backed implementation of set, but the fundamental algorithm is the same in both cases.

If your items are already stored in a list for other reasons, then you'll have to convert them to a set before using the subset test approach. Then the speedup drops to about 2.5x:

>>> %timeit bigset >= set(bigsubseq)
2.1 ms ± 49.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

And if your container is a sequence, and needs to be converted first, then the speedup is even smaller:

>>> %timeit set(bigseq) >= set(bigsubseq)
4.36 ms ± 31.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

The only time we get disastrously slow results is when we leave container as a sequence:

>>> %timeit all(x in bigseq for x in bigsubseq)
184 ms ± 994 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

And of course, we'll only do that if we must. If all the items in bigseq are hashable, then we'll do this instead:

>>> %timeit bigset = set(bigseq); all(x in bigset for x in bigsubseq)
7.24 ms ± 78 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

That's just 1.66x faster than the alternative (set(bigseq) >= set(bigsubseq), timed above at 4.36).

So subset testing is generally faster, but not by an incredible margin. On the other hand, let's look at when all is faster. What if items is ten-million values long, and is likely to have values that aren't in container?

>>> %timeit hugeiter = (x * 10 for bss in [bigsubseq] * 2000 for x in bss); set(bigset) >= set(hugeiter)
13.1 s ± 167 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
>>> %timeit hugeiter = (x * 10 for bss in [bigsubseq] * 2000 for x in bss); all(x in bigset for x in hugeiter)
2.33 ms ± 65.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Converting the generator into a set turns out to be incredibly wasteful in this case. The set constructor has to consume the entire generator. But the short-circuiting behavior of all ensures that only a small portion of the generator needs to be consumed, so it's faster than a subset test by four orders of magnitude.

This is an extreme example, admittedly. But as it shows, you can't assume that one approach or the other will be faster in all cases.

The Upshot

Most of the time, converting container to a set is worth it, at least if all its elements are hashable. That's because in for sets is O(1), while in for sequences is O(n).

On the other hand, using subset testing is probably only worth it sometimes. Definitely do it if your test items are already stored in a set. Otherwise, all is only a little slower, and doesn't require any additional storage. It can also be used with large generators of items, and sometimes provides a massive speedup in that case.

You can use the combinat package with R 2.13:

install.packages("combinat")
require(combinat)
permn(3)
combn(3, 2)

If you want to know the number of combination/permutations, then check the size of the result, e.g.:

length(permn(3))
dim(combn(3,2))[2]

if you need to do something before submitting data, you could use form's onsubmit.

<form method=post onsubmit="return doSomething()">
  <input type=text name=text1>
  <input type=submit>
</form>

You can use PropertyConfigurator to load your log4j.properties wherever it is located in the disk.

Example:

Logger logger = Logger.getLogger(this.getClass());
String log4JPropertyFile = "C:/this/is/my/config/path/log4j.properties";
Properties p = new Properties();

try {
    p.load(new FileInputStream(log4JPropertyFile));
    PropertyConfigurator.configure(p);
    logger.info("Wow! I'm configured!");
} catch (IOException e) {
    //DAMN! I'm not....

}

If you have an XML Log4J configuration, use DOMConfigurator instead.

Why don't you start using OAuth with JSON WebTokens

http://projects.spring.io/spring-security-oauth/

OAuth2 is an standardized authorization protocol/framework. As per Official OAuth2 Specification:

You can find more info here

See documentation here: http://www.postgresql.org/docs/current/interactive/sql-altertable.html

ALTER TABLE tbl_name ALTER COLUMN col_name TYPE varchar (11);

Use the ampersand & to glue variables together:

$url = "http://localhost/main.php?email=$email_address&event_id=$event_id";
//                               ^ start of vars      ^next var

Casting the integer to a char will do what you want.

char theChar=' ';
int theInt = 97;
theChar=(char) theInt;

cout<<theChar<<endl;

There is no difference between 'a' and 97 besides the way you interperet them.

You don't need to copy a Python string. They are immutable, and the copy module always returns the original in such cases, as do str(), the whole string slice, and concatenating with an empty string.

Moreover, your 'hello' string is interned (certain strings are). Python deliberately tries to keep just the one copy, as that makes dictionary lookups faster.

One way you could work around this is to actually create a new string, then slice that string back to the original content:

>>> a = 'hello'
>>> b = (a + '.')[:-1]
>>> id(a), id(b)
(4435312528, 4435312432)

But all you are doing now is waste memory. It is not as if you can mutate these string objects in any way, after all.

If all you wanted to know is how much memory a Python object requires, use sys.getsizeof(); it gives you the memory footprint of any Python object.

For containers this does not include the contents; you'd have to recurse into each container to calculate a total memory size:

>>> import sys
>>> a = 'hello'
>>> sys.getsizeof(a)
42
>>> b = {'foo': 'bar'}
>>> sys.getsizeof(b)
280
>>> sys.getsizeof(b) + sum(sys.getsizeof(k) + sys.getsizeof(v) for k, v in b.items())
360

You can then choose to use id() tracking to take an actual memory footprint or to estimate a maximum footprint if objects were not cached and reused.

I noticed that //noinspection can be auto-generated in IntelliJ

• make sure you have not already a plan @SuppressWarninigs before the statement
• Now you can auto-generate the specific //noinspection by hitting Alt+Enter when you have the warning selected and then use the right arrow key to see the Suppress for ... option

Ended up here when I wanted to suppress a "switch has too few case labels" warning from IntelliJ. I did not find a complete List for IntelliJ's @SuppressWarning support but //noinspection did the trick for me.

Hiding an element and then showing it again within a setTimeout of 0 will force a redraw.

$('#page').hide();
setTimeout(function() {
    $('#page').show();
}, 0);

The text 'dasda' will never not be within a tag, right? Semantically and to be valid HTML it as to be, just add the clear class to that:

Assertions are generally used primarily as a means of checking the program's expected behavior. It should lead to a crash in most cases, since the programmer's assumptions about the state of the program are false. This is where the debugging aspect of assertions come in. They create a checkpoint that we simply can't ignore if we would like to have correct behavior.

In your case it does data validation on the incoming parameters, though it does not prevent clients from misusing the function in the future. Especially if they are not, (and should not) be included in release builds.

This is not the recommended way to solve this error but you can suppress it quickly, it will do the job . I prefer this for prototypes or demos . add

in Form1() constructor .

Set the user name as data-username attribute to the button and also a class:

HTML

<input type="button" name="theButton" value="Detail" class="btn" data-username="{{result['username']}}" />

JS

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name != undefined && name != null) {
        window.location = '/player_detail?username=' + name;
    }
});?

EDIT:

Also, you can simply check for undefined && null using:

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name) {
        window.location = '/player_detail?username=' + name;
    }
});?

As, mentioned in this answer

if (name) {            
}

will evaluate to true if value is not:

• null
• undefined
• NaN
• empty string ("")
• 0
• false

The above list represents all possible falsy values in ECMA/Javascript.

FileStream fs= File.Create(ConfigurationManager.AppSettings["file"]);

The syntaxes

int[]

and

int[X] // Where X is a compile-time positive integer

are exactly the same as

int*

when in a function parameter list (I left out the optional names).

Additionally, an array name decays to a pointer to the first element when passed to a function (and not passed by reference) so both int firstarray[3] and int secondarray[5] decay to int*s.

It also happens that both an array dereference and a pointer dereference with subscript syntax (subscript syntax is x[y]) yield an lvalue to the same element when you use the same index.

These three rules combine to make the code legal and work how you expect; it just passes pointers to the function, along with the length of the arrays which you cannot know after the arrays decay to pointers.

For Nginx:

1. openssl req -newkey rsa:2048 -nodes -keyout domain.com.key -out domain.com.csr

2. SSL file domain_com.crt and domain_com.ca-bundle files, then copy new file in paste domain.com.chained.crt.

3: Add nginx files:

1. ssl_certificate /home/user/domain_ssl/domain.com.chained.crt;
2. ssl_certificate_key /home/user/domain_ssl/domain.com.key;

Lates restart Nginx.

With jQuery it will be something like that:

$(document).ready(function() {
  $('#yourDiv').on('mousedown', function(e) {
      e.preventDefault();
  });
});

In my case I wanted to disable the user from drop text in the inputs so I used "drop" instead "mousedown".

$(document).ready(function() {
  $('input').on('drop', function(event) {
    event.preventDefault();
  });
});

Instead event.preventDefault() you can return false. Here's the difference.

And the code:

$(document).ready(function() {
  $('input').on('drop', function() {
    return false;
  });
});

Update: note that the currently accepted answer perpetuates a common misunderstanding about the behaviour of git push, which hasn't been corrected despite a comment pointing it out.

Your summary of what remotes are - like a nickname for the URL of a repository - is correct.

So why does the URL not git://[email protected]/peter/first_app.git but in the other syntax -- what syntax is it? Why must it end with .git? I tried not using .git at the end and it works too. If not .git, what else can it be? The git at the beginner seems to be a user account on the git server?

The two URLs that you've mentioned indicate that two different transport protocols should be used. The one beginning with git:// is for the git protocol, which is usually only used for read-only access to repositories. The other one, [email protected]:peter/first_app.git, is one of the different ways of specifying access to a repository over SSH - this is the "scp-style syntax" described in the documentation. That the username in the scp-style syntax is git is because of the way that GitHub deals with identifying users - essentially that username is ignored, and the user is identified based on the SSH key-pair that they used to authenticate.

As for the verbosity of git push origin master, you've noticed that after the first push, you can then just do git push. This is because of a series of difficult-to-remember-but-generally-helpful defaults :)

• If no remote is specified, the remote configured for the current branch (in remote.master.url in your case) is used. If that's not set up, then origin is used.
• If there's no "refspec" (e.g. master, master:my-experiment, etc.) specified, then git defaults to pushing every local branch that has the same name as a branch on the remote. If you just have a branch called master in common between your repository and the remote one, that'll be the same as pushing your master to the remote master.

Personally, since I tend to have many topic branches (and often several remotes) I always use the form:

git push origin master

... to avoid accidentally pushing other branches.

In reply to your comments on one of the other answers, it sounds to me as if are learning about git in a top-down way very effectively - you've discovered that the defaults work, and your question is asking about why ;) To be more serious, git can be used essentially as simply as SVN, but knowing a bit about remotes and branches means you can use it much more flexibily and this can really change the way you work for the better. Your remark about a semester course makes me think of something Scott Chacon said in a podcast interview - students are taught about all kinds of basic tools in computer science and software engineering, but very rarely version control. Distributed version control systems such as git and Mercurial are now so important, and so flexible, that it would be worth teaching courses on them to give people a good grounding.

My view is that with git, this learning curve is absolutely worth it - working with lots of topic branches, merging them easily, and pushing and pulling them about between different repositories is fantastically useful once you become confident with the system. It's just unfortunate that:

• The primary documentation for git is so hard to parse for newcomers. (Although I'd argue that if you Google for almost any git question, helpful tutorial material (or Stack Overflow answers :)) come up nowadays.)
• There are a few odd behaviours in git that are hard to change now because many scripts may rely on them, but are confusing to people.

In gcc, this isn't supported. In fact, this isn't supported in any existing compiler/linker i'm aware of.

Robust C89 strtol-based solution

With:

• no undefined behavior (as could be had with the atoi family)
• a stricter definition of integer than strtol (e.g. no leading whitespace nor trailing trash chars)
• classification of the error case (e.g. to give useful error messages to users)
• a "testsuite"

#include <assert.h>
#include <ctype.h>
#include <errno.h>
#include <limits.h>
#include <stdio.h>
#include <stdlib.h>

    STR2INT_OVERFLOW,
    STR2INT_UNDERFLOW,

 *
 * @param[out] out The converted int. Cannot be NULL.
 *
 * @param[in] s Input string to be converted.
 *
 *     The format is the same as strtol,
 *     except that the following are inconvertible:

 *     - any trailing characters that are not part of the number

As @Mehmet is pointing out, if your result is returning more then 1 elerment then you need to look into you data as i suspect that its not by design that you have customers sharing a customernumber.

But to the point i wanted to give you a quick overview.

//success on 0 or 1 in the list, returns dafault() of whats in the list if 0
list.SingleOrDefault();
//success on 1 and only 1 in the list
list.Single();

//success on 0-n, returns first element in the list or default() if 0 
list.FirstOrDefault();
//success 1-n, returns the first element in the list
list.First();

//success on 0-n, returns first element in the list or default() if 0 
list.LastOrDefault();
//success 1-n, returns the last element in the list
list.Last();

for more Linq expressions have a look at System.Linq.Expressions

It can be a mathematical convention in the definition of an interval where square brackets mean "extremal inclusive" and round brackets "extremal exclusive".

You have to use code similar to this:

echo "<div id='divwithform'>";

if(isset($_POST['submit']))  // if form was submitted (if you came here with form data)
{
    echo "Success";
}
else                // if form was not submitted (if you came here without form data)
{
    echo "<form> ... </form>";
} 

echo "</div>";

Code with if like this is typical for many pages, however this is very simplified.

Normally, you have to validate some data in first "if" (check if form fields were not empty etc).

Please visit www.thenewboston.org or phpacademy.org. There are very good PHP video tutorials, including forms.

You cannot trust g++ 4.6.3 here with 64 bit integers on a 32 bit intel platform. a/b is computed by a call to divdi3 and a%b is computed by a call to moddi3. I can even come up with an example that computes a/b and a-b*(a/b) with these calls. So I use c=a/b and a-b*c.

The div method gives a call to a function which computes the div structure, but a function call seems inefficient on platforms which have hardware support for the integral type (i.e. 64 bit integers on 64 bit intel/amd platforms).

In my case I was trying to show a DialogFragment containing a pager and this exception was thrown when the FragmentPagerAdapter attempted to add the Fragments to the pager. Based on howettl answer I guess that it was due to the Pager parent was not the view set in setContentView() in my FragmentActivity.

The only change I did to solve the problem was to create the FragmentPagerAdapter passing in a FragmentMager obtained by calling getChildFragmentManager(), not the one obtained by calling getFragmentManager() as I normally do.

    public class PagerDialog extends DialogFragment{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.pager_dialog, container, false);

        MyPagerAdapter pagerAdapter = new MyPagerAdapter(getChildFragmentManager());
        ViewPager pager = (ViewPager) rootView.findViewById(R.id.pager);
        pager.setAdapter(pagerAdapter);

        return rootView;
    }
}

No, there are definitely times where you would not want to use [unowned self]. Sometimes you want the closure to capture self in order to make sure that it is still around by the time the closure is called.

Example: Making an asynchronous network request

If you are making an asynchronous network request you do want the closure to retain self for when the request finishes. That object may have otherwise been deallocated but you still want to be able to handle the request finishing.

When to use unowned self or weak self

The only time where you really want to use [unowned self] or [weak self] is when you would create a strong reference cycle. A strong reference cycle is when there is a loop of ownership where objects end up owning each other (maybe through a third party) and therefore they will never be deallocated because they are both ensuring that each other stick around.

In the specific case of a closure, you just need to realize that any variable that is referenced inside of it, gets "owned" by the closure. As long as the closure is around, those objects are guaranteed to be around. The only way to stop that ownership, is to do the [unowned self] or [weak self]. So if a class owns a closure, and that closure captures a strong reference to that class, then you have a strong reference cycle between the closure and the class. This also includes if the class owns something that owns the closure.

Specifically in the example from the video

In the example on the slide, TempNotifier owns the closure through the onChange member variable. If they did not declare self as unowned, the closure would also own self creating a strong reference cycle.

Difference between unowned and weak

The difference between unowned and weak is that weak is declared as an Optional while unowned is not. By declaring it weak you get to handle the case that it might be nil inside the closure at some point. If you try to access an unowned variable that happens to be nil, it will crash the whole program. So only use unowned when you are positive that variable will always be around while the closure is around

First, close all instances of Google Chrome. There should be no instances of chrome.exe running in the Windows Task Manager. Then

• Go to %LOCALAPPDATA%\Google\Chrome\User Data\Default\.
• Open the file "Preferences" in a text editor like Notepad.
• First, resave the file to something like "Preference - Old" without any extension (i.e. no .txt). This will serve as a backup, should something go wrong.
• Look for a section called "browser." Inside that section, you should find a subsection called window_placement. Under window_placement you will see things like "bottom", "left", "right", etc. with numbers after them.

You will need to play around with these numbers to get your desired window size and placement. When finished, save this file with the name "Preferences" again with no extension. This will overwrite the existing Preferences file. Open Chrome and see how you did. If you're not satisfied with the size and placement, close Chrome and change the numbers in the Preferences file until you get what you want.

No, you must have an Intel Mac of some sort. I went to Best Buy and got a 24" iMac with 4G RAM for $1499 using their 18 month no interest promotion. I pay a minimum payment of something like $16 a month. As long as I pay the entire thing off within 18 months - no interest. That was the only way I was getting into iPhone development.

You can get a really nice, visual output of how your branches differ with this

git log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr)%Creset' --abbrev-commit --date=relative master..branch-X

You might be able to do this with AutoGenerateColumns and a DataTemplate. I'm not positive if it would work without a lot of work, you would have to play around with it. Honestly if you have a working solution already I wouldn't make the change just yet unless there's a big reason. The DataGrid control is getting very good but it still needs some work (and I have a lot of learning left to do) to be able to do dynamic tasks like this easily.

Can you use default android Crop functionality?

Here is my code

private void performCrop(Uri picUri) {
    try {
        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        // indicate image type and Uri
        cropIntent.setDataAndType(picUri, "image/*");
        // set crop properties here
        cropIntent.putExtra("crop", true);
        // indicate aspect of desired crop
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);
        // indicate output X and Y
        cropIntent.putExtra("outputX", 128);
        cropIntent.putExtra("outputY", 128);
        // retrieve data on return
        cropIntent.putExtra("return-data", true);
        // start the activity - we handle returning in onActivityResult
        startActivityForResult(cropIntent, PIC_CROP);
    }
    // respond to users whose devices do not support the crop action
    catch (ActivityNotFoundException anfe) {
        // display an error message
        String errorMessage = "Whoops - your device doesn't support the crop action!";
        Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
        toast.show();
    }
}

declare:

final int PIC_CROP = 1;

at top.

In onActivity result method, writ following code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PIC_CROP) {
        if (data != null) {
            // get the returned data
            Bundle extras = data.getExtras();
            // get the cropped bitmap
            Bitmap selectedBitmap = extras.getParcelable("data");

            imgView.setImageBitmap(selectedBitmap);
        }
    }
}

It is pretty easy for me to implement and also shows darken areas.

I use div instead of tables and am able to target classes within the main class, as below:

CSS

.main {
    .width: 800px;
    .margin: 0 auto;
    .text-align: center;
}
.main .table {
    width: 80%;
}
.main .row {
   / ***something ***/
}
.main .column {
    font-size: 14px;
    display: inline-block;
}
.main .left {
    width: 140px;
    margin-right: 5px;
    font-size: 12px;
}
.main .right {
    width: auto;
    margin-right: 20px;
    color: #fff;
    font-size: 13px;
    font-weight: normal;
}

HTML

<div class="main">
    <div class="table">
        <div class="row">
            <div class="column left">Swing Over Bed</div>
            <div class="column right">650mm</div>
            <div class="column left">Swing In Gap</div>
            <div class="column right">800mm</div>
        </div>
    </div>
</div>

If you want to style a particular "cell" exclusively you can use another sub-class or the id of the div e.g:

.main #red { color: red; }

<div class="main">
    <div class="table">
        <div class="row">
            <div id="red" class="column left">Swing Over Bed</div>
            <div class="column right">650mm</div>
            <div class="column left">Swing In Gap</div>
            <div class="column right">800mm</div>
        </div>
    </div>
</div>

By using a border-radius of 50% you can make a circle. Here is an example:

CSS:

#exampleCircle{
    width: 500px;
    height: 500px;
    background: red;
    border-radius: 50%;
}

HTML:

<div id = "exampleCircle"></div>

You can use lodash: https://lodash.com/docs

_.chunk(['a', 'b', 'c', 'd'], 2);
// ? [['a', 'b'], ['c', 'd']]

Here's a useful little function, which makes using/creating iOS folders a little easier.

You pass it the name of a subfolder, it'll return the full path back to you, and make sure the directory exists.

(Personally, I stick this static function in my AppDelete class, but perhaps this isn't the smartest place to put it.)

Here's how you would call it, to get the "full path" of a MySavedImages subdirectory:

NSString* fullPath = [AppDelegate getFullPath:@"MySavedImages"];

And here's the full function:

+(NSString*)getFullPath:(NSString*)folderName
{
    //  Check whether a subdirectory exists in our sandboxed Documents directory.
    //  Returns the full path of the directory.
    //
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    if (paths.count < 1)
        return nil;

    NSString *rootFolder = [paths firstObject];
    NSString* fullFolderPath = [rootFolder stringByAppendingPathComponent:folderName];

    BOOL isDirectory;
    NSFileManager* manager = [NSFileManager defaultManager];

    if (![manager fileExistsAtPath:fullFolderPath isDirectory:&isDirectory] || !isDirectory) {
        NSError *error = nil;
        NSDictionary *attr = [NSDictionary dictionaryWithObject:NSFileProtectionComplete
                                                         forKey:NSFileProtectionKey];
        [manager createDirectoryAtPath:fullFolderPath
           withIntermediateDirectories:YES
                            attributes:attr
                                 error:&error];
        if (error) {
            NSLog(@"Error creating directory path: %@", [error localizedDescription]);
            return nil;
        }
    }
    return fullFolderPath;
}

Using this little function, it's easy to create a directory in your app's Documents directory (if it doesn't already exist), and to write a file into it.

Here's how I would create the directory, and write the contents of one of my image files into it:

//  Let's create a "MySavedImages" subdirectory (if it doesn't already exist)
NSString* fullPath = [AppDelegate getFullPath:@"MySavedImages"];

//  As an example, let's load the data in one of my images files
NSString* imageFilename = @"icnCross.png";

UIImage* image = [UIImage imageNamed:imageFilename];
NSData *imageData = UIImagePNGRepresentation(image);

//  Obtain the full path+filename where we can write this .png to, in our new MySavedImages directory
NSString* imageFilePathname = [fullPath stringByAppendingPathComponent:imageFilename];

//  Write the data
[imageData writeToFile:imageFilePathname atomically:YES];

Hope this helps !

You could use curl instead. It is installed by default into /usr/bin.

For most use cases, it's not correct to register MultipartFilter in web.xml because Spring MVC already does the work of processing your multipart request. It's even written in the filter's javadoc.

On the server side, define a multipartResolver bean in your app context:

@Bean
public CommonsMultipartResolver multipartResolver(){
    CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setDefaultEncoding("utf-8");
    commonsMultipartResolver.setMaxUploadSize(50000000);
    return commonsMultipartResolver;
}

On the client side, here's how to prepare the request for use with Spring RestTemplate API:

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    LinkedMultiValueMap<String, String> pdfHeaderMap = new LinkedMultiValueMap<>();
    pdfHeaderMap.add("Content-disposition", "form-data; name=filex; filename=" + file.getOriginalFilename());
    pdfHeaderMap.add("Content-type", "application/pdf");
    HttpEntity<byte[]> doc = new HttpEntity<byte[]>(file.getBytes(), pdfHeaderMap);

    LinkedMultiValueMap<String, Object> multipartReqMap = new LinkedMultiValueMap<>();
    multipartReqMap.add("filex", doc);

    HttpEntity<LinkedMultiValueMap<String, Object>> reqEntity = new HttpEntity<>(multipartReqMap, headers);
    ResponseEntity<MyResponse> resE = restTemplate.exchange(uri, HttpMethod.POST, reqEntity, MyResponse.class);

The important thing is really to provide a Content-disposition header using the exact case, and adding name and filename specifiers, otherwise your part will be discarded by the multipart resolver.

Then, your controller method can handle the uploaded file with the following argument:

@RequestParam("filex") MultipartFile file

Hope this helps.

This is the right CSS3 answer. Hope this helps you somehow now :D I really recommend you to read the book: https://www.amazon.com/Book-CSS3-Developers-Future-Design/dp/1593272863 Actually I have made this solution from reading this book now. :D

I hope i am not too late, this solution here worked for me, i am using COMODO SSL, the above solutions seem invalid over time, my website lifetanstic.co.ke

Instead of contacting Comodo Support and gain a CA bundle file You can do the following:

When You get your new SSL cert from Comodo (by mail) they have a zip file attached. You need to unzip the zip-file and open the following files in a text editor like notepad:

AddTrustExternalCARoot.crt
COMODORSAAddTrustCA.crt
COMODORSADomainValidationSecureServerCA.crt

Then copy the text of each ".crt" file and paste the texts above eachother in the "Certificate Authority Bundle (optional)" field.

After that just add the SSL cert as usual in the "Certificate" field and click at "Autofil by Certificate" button and hit "Install".

html_entity_decode('エ', 0, 'UTF-8');

This works too. However the json_decode() solution is a lot faster (around 50 times).

I recommend trying to downgrade DJANGO to version 2.1.1.

What about:

@echo off
set myvar="the list: "
for /r %%i in (*.doc) DO call :concat %%i
echo %myvar%
goto :eof

:concat
set myvar=%myvar% %1;
goto :eof

If all else fails, look for duplication. I was misdirected by the explicit initial reference to constructors and destructors until I read a reference in another post. It's any unresolved method. In my case, I thought I had replaced the declaration that used char *xml as the parameter with one using the unnecessarily troublesome const char *xml, but instead, I had created a new one and left the other one in place.

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

For those using frameworks that compress, bundle, and minify files, make sure you define each dependency explicitly as these frameworks tend to rename your variables. That happened to me while using ASP.NET BundleConfig.cs to bundle my app scripts together.

Before

app.config(function($routeProvider) {
    $routeProvider.
      when('/', {
          templateUrl: 'list.html',
          controller: 'ListController'
      }).
      when('/items/:itemId', {
          templateUrl: 'details.html',
          controller: 'DetailsController'
      }).
      otherwise({
          redirectTo: '/'
      });
});

After

app.config(["$routeProvider", function($routeProvider) {
    $routeProvider.
      when('/', {
          templateUrl: 'list.html',
          controller: 'ListController'
      }).
      when('/items/:itemId', {
          templateUrl: 'details.html',
          controller: 'DetailsController'
      }).
      otherwise({
          redirectTo: '/'
      });
}]);

You have to use babel-preset-env and nodemon for hot-reload.

Then create .babelrc file with below content:

{
  "presets": ["env"]
}

Finally, create script in package.json:

"scripts": {
    "babel-node": "babel-node --presets=env",
    "start": "nodemon --exec npm run babel-node -- ./index.js",
    "build": "babel src -d dist"
  }

Or just use this boilerplate:

Boilerplate: node-es6

Selected answer throws exceptions, and the answer from Carlos Toledo applies filtering after retrieving all values from the database.

The following one runs a single round-trip and reads a single value, using any possible indexes, without an exception.

int maxAge = _dbContext.Persons
  .OrderByDescending(p => p.Age)
  .Select(p => p.Age)
  .FirstOrDefault();

Assuming you're dealing with Windows 7 x64 and something that was previously installed with some sort of an installer, you can open regedit and search the keys under

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

(which references 32-bit programs) for part of the name of the program, or

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

(if it actually was a 64-bit program).

If you find something that matches your program in one of those, the contents of UninstallString in that key usually give you the exact command you are looking for (that you can run in a script).

If you don't find anything relevant in those registry locations, then it may have been "installed" by unzipping a file. Because you mentioned removing it by the Control Panel, I gather this likely isn't then case; if it's in the list of programs there, it should be in one of the registry keys I mentioned.

Then in a .bat script you can do

if exist "c:\program files\whatever\program.exe" (place UninstallString contents here)
if exist "c:\program files (x86)\whatever\program.exe" (place UninstallString contents here)

The below packages are also helps you,

yum install gcc glibc glibc-common gd gd-devel -y

This is not the exact answer, but this might be helpful for the people looking to solve some problem with the approach of ordering row before group by in mysql.

I came to this thread, when I wanted to find the latest row(which is order by date desc but get the only one result for a particular column type, which is group by column name).

One other approach to solve such problem is to make use of aggregation.

So, we can let the query run as usual, which sorted asc and introduce new field as max(doc) as latest_doc, which will give the latest date, with grouped by the same column.

Suppose, you want to find the data of a particular column now and max aggregation cannot be done. In general, to finding the data of a particular column, you can make use of GROUP_CONCAT aggregator, with some unique separator which can't be present in that column, like GROUP_CONCAT(string SEPARATOR ' ') as new_column, and while you're accessing it, you can split/explode the new_column field.

Again, this might not sound to everyone. I did it, and liked it as well because I had written few functions and I couldn't run subqueries. I am working on codeigniter framework for php.

Not sure of the complexity as well, may be someone can put some light on that.

Regards :)

This answer from Roy Tinker here:

var date = new Date(parseInt(jsonDate.substr(6)));

As he says: The substr function takes out the "/Date(" part, and the parseInt function gets the integer and ignores the ")/" at the end. The resulting number is passed into the Date constructor.

Another option is to simply format your information properly on the ASP side such that JavaScript can easily read it. Consider doing this for your dates:

DateTime.Now()

Which should return a format like this:

7/22/2008 12:11:04 PM

If you pass this into a JavaScript Date constructor like this:

var date = new Date('7/22/2008 12:11:04 PM');

The variable date now holds this value:

Tue Jul 22 2008 12:11:04 GMT-0700 (Pacific Daylight Time)

Naturally, you can format this DateTime object into whatever sort of string/int the JS Date constructor accepts.

Use this, Tested and 100% Worked!

For VB.NET

Dim myString As String
Dim oldValue As String
Dim newValue As String

myString = Form1.TextBox1.Text
oldValue = TextBox1.Text
newValue = TextBox2.Text

Dim working As String = myString
Dim index As Integer = working.IndexOf(oldValue, StringComparison.CurrentCultureIgnoreCase)

While index <> -1
    working = working.Remove(index, oldValue.Length)
    working = working.Insert(index, newValue)
    index = index + newValue.Length
    index = working.IndexOf(oldValue, index, StringComparison.CurrentCultureIgnoreCase)
    Form1.TextBox1.Text = working
End While

For C#

private void Button2_Click(System.Object sender, System.EventArgs e)
{
    string myString;
    string oldValue;
    string newValue;

    myString = Form1.TextBox1.Text;
    oldValue = TextBox1.Text;
    newValue = TextBox2.Text;

    string working = myString;
    int index = working.IndexOf(oldValue, StringComparison.CurrentCultureIgnoreCase);

    while (index != -1)
    {
        working = working.Remove(index, oldValue.Length);
        working = working.Insert(index, newValue);
        index = index + newValue.Length;
        index = working.IndexOf(oldValue, index, StringComparison.CurrentCultureIgnoreCase);
        Form1.TextBox1.Text = working;
    }
}

I took Mr. Fooz's code and also added Arlen's solution too and here are the timings that I've gotten for Octave:

clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic; for i=1:N, V1 = V/norm(V);         end; toc % 7.0 s
tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 6.4 s
tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 5.5 s
tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 6.6 s
tic; for i=1:N, V1 = V/norm(V);         end; toc % 7.1 s
tic; for i=1:N, d = 1/norm(V); V1 = V*d;end; toc % 4.7 s

Then, because of something I'm currently looking at, I tested out this code for ensuring that each row sums to 1:

clc; clear all;
m = 2048;
V = rand(m);
N = 100;
tic; for i=1:N, V1 = V ./ (sum(V,2)*ones(1,m));                end; toc % 8.2 s
tic; for i=1:N, V2 = bsxfun(@rdivide, V, sum(V,2));            end; toc % 5.8 s
tic; for i=1:N, V3 = bsxfun(@rdivide, V, V*ones(m,1));         end; toc % 5.7 s
tic; for i=1:N, V4 = V ./ (V*ones(m,m));                       end; toc % 77.5 s
tic; for i=1:N, d = 1./sum(V,2);V5 = bsxfun(@times, V, d);     end; toc % 2.83 s
tic; for i=1:N, d = 1./(V*ones(m,1));V6 = bsxfun(@times, V, d);end; toc % 2.75 s
tic; for i=1:N, V1 = V ./ (sum(V,2)*ones(1,m));                end; toc % 8.2 s

You can override Django save method official doc about it.

The modified version of your code:

class Order(models.Model):
    cart = models.ForeignKey(Cart)
    add_date = models.DateTimeField(auto_now_add=True)
    order_number = models.IntegerField(default=0)  # changed here
    enable = models.BooleanField(default=True)

    def save(self, *args, **kwargs):
        self.order_number = self.order_number + 1
        super().save(*args, **kwargs)  # Call the "real" save() method.

Another way is to use signals. More one:

1. official Django docs about pre-save
2. stackoverflow example about using pre-save signal

Just use the below code to resolve this:

JsonObject obj = Json.createReader(new ByteArrayInputStream(Base64.getDecoder().decode(accessToken.split("\\.")[1].
                        replace('-', '+').replace('_', '/')))).readObject();

In the above code replace('-', '+').replace('_', '/') did the job. For more details see the https://jwt.io/js/jwt.js. I understood the problem from the part of the code got from that link:

function url_base64_decode(str) {
  var output = str.replace(/-/g, '+').replace(/_/g, '/');
  switch (output.length % 4) {
    case 0:
      break;
    case 2:
      output += '==';
      break;
    case 3:
      output += '=';
      break;
    default:
      throw 'Illegal base64url string!';
  }
  var result = window.atob(output); //polifyll https://github.com/davidchambers/Base64.js
  try{
    return decodeURIComponent(escape(result));
  } catch (err) {
    return result;
  }
}

Below program produce the result as needed:

#include <stdio.h>
 
unsigned int Little_To_Big_Endian(unsigned int num);
 
int main( )
{
    int num = 0x11223344 ;
    
    printf("\n Little_Endian = 0x%X\n",num);
    
    printf("\n Big_Endian    = 0x%X\n",Little_To_Big_Endian(num));
 
}
 
unsigned int Little_To_Big_Endian(unsigned int num)
{
    return (((num >> 24) & 0x000000ff) | ((num >> 8) & 0x0000ff00) | ((num << 8) & 0x00ff0000) | ((num << 24) & 0xff000000));
}

And also below function can be used:

    unsigned int Little_To_Big_Endian(unsigned int num)
    {
        return (((num & 0x000000ff) << 24) | ((num & 0x0000ff00) << 8 ) | ((num & 0x00ff0000) >> 8) | ((num & 0xff000000) >> 24 ));
    }

I know this is quite an old question -

A = [[1, 2, 3],
     [4, 5, 6],
     [7, 8, 9]]

Let's say, you want to extract the first 2 rows and first 3 columns

A_NEW = A[0:2, 0:3]
A_NEW = [[1, 2, 3],
         [4, 5, 6]]

Understanding the syntax

A_NEW = A[start_index_row : stop_index_row, 
          start_index_column : stop_index_column)]

If one wants row 2 and column 2 and 3

A_NEW = A[1:2, 1:3]

After checking out my branch in Egit, I switched to the Java View, then used File-->Import, Git-->Projects from Git, then selected the top level maven directory. This was with Eclipse Kepler.

Note that the ::first-letter selector does not work with inline elements, so it must be either block or inline-block, as follows:

.m_title {display:inline-block}
.m_title:first-letter {text-transform: uppercase}

First

ps -ef

to list all processes. Note the the process number of the one you want to kill. Then

kill 1234

were you replace 1234 with the process number that you want.

Alternatively, if you are absolutely certain that there is only one process with a particular name, or you want to kill multiple processes which share the same name

killall processname

I'm a little surprised that this question has been asked so many times before, but the most reuseable and friendly solution hasn't been documented.

I often have webpages using AngularJS, and when I click on a Save button, I'll "POST" this data back to my .aspx page or .ashx handler to save this back to the database. The data will be in the form of a JSON record.

On the server, to turn the raw posted data back into a C# class, here's what I would do.

First, define a C# class which will contain the posted data.

Supposing my webpage is posting JSON data like this:

{
    "UserID" : 1,
    "FirstName" : "Mike",
    "LastName" : "Mike",
    "Address1" : "10 Really Street",
    "Address2" : "London"
}

Then I'd define a C# class like this...

public class JSONRequest
{
    public int UserID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
}

(These classes can be nested, but the structure must match the format of the JSON data. So, if you're posting a JSON User record, with a list of Order records within it, your C# class should also contain a List<> of Order records.)

Now, in my .aspx.cs or .ashx file, I just need to do this, and leave JSON.Net to do the hard work...

    protected void Page_Load(object sender, EventArgs e)
    {
        string jsonString = "";
        HttpContext.Current.Request.InputStream.Position = 0;
        using (StreamReader inputStream = new StreamReader(this.Request.InputStream))
        {
            jsonString = inputStream.ReadToEnd();
        }
        JSONRequest oneQuestion = JsonConvert.DeserializeObject<JSONRequest>(jsonString);

And that's it. You now have a JSONRequest class containing the various fields which were POSTed to your server.

You can use the Get-InstalledModule

If (-not(Get-InstalledModule SomeModule -ErrorAction silentlycontinue)) {
  Write-Host "Module does not exist"
}
Else {
  Write-Host "Module exists"
}

You can do:

foo.instance_of?(String)

And the more general:

foo.kind_of?(String)

Most likely, the userdata() function is returning an object, not a string. Look into the documentation (or var_dump the return value) to find out which value you need to use.

Info on MySQL's full text search. This is restricted to MyISAM tables, so may not be suitable if you wantto use a different table type.

http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html

Even if WHERE textcolumn LIKE "%SUBSTRING%" is going to be slow, I think it is probably better to let the Database handle it rather than have PHP handle it. If it is possible to restrict searches by some other criteria (date range, user, etc) then you may find the substring search is OK (ish).

If you are searching for whole words, you could pull out all the individual words into a separate table and use that to restrict the substring search. (So when searching for "my search string" you look for the the longest word "search" only do the substring search on records containing the word "search")

The existing answers are good but don't cover what to do when a smart pointer is not the (complete) answer to the problem you are trying to solve.

Among other things (explained well in other answers) using a smart pointer is a possible solution to How do we use a abstract class as a function return type? which has been marked as a duplicate of this question. However, the first question to ask if tempted to specify an abstract (or in fact, any) base class as a return type in C++ is "what do you really mean?". There is a good discussion (with further references) of idiomatic object oriented programming in C++ (and how this is different to other languages) in the documentation of the boost pointer container library. In summary, in C++ you have to think about ownership. Which smart pointers help you with, but are not the only solution, or always a complete solution (they don't give you polymorphic copy) and are not always a solution you want to expose in your interface (and a function return sounds an awful lot like an interface). It might be sufficient to return a reference, for example. But in all of these cases (smart pointer, pointer container or simply returning a reference) you have changed the return from a value to some form of reference. If you really needed copy you may need to add more boilerplate "idiom" or move beyond idiomatic (or otherwise) OOP in C++ to more generic polymorphism using libraries like Adobe Poly or Boost.TypeErasure.

Unload Me only works when its called from userform self. If you want to close a form from another module code (or userform), you need to use the Unload function + userformtoclose name.

This is a clarification because I have seen things done in code which are honestly confusing - I think the following example might assist others.

As others have said before - Bitmap inherits from the Abstract Image class

Abstract effectively means you cannot create a New() instance of it.

    Image imgBad1 = new Image();        // Bad - won't compile
    Image imgBad2 = new Image(200,200); // Bad - won't compile

But you can do the following:

    Image imgGood;  // Not instantiated object!
    // Now you can do this
    imgGood = new Bitmap(200, 200);

You can now use imgGood as you would the same bitmap object if you had done the following:

    Bitmap bmpGood = new Bitmap(200,200);

The nice thing here is you can draw the imgGood object using a Graphics object

    Graphics gr = default(Graphics);
    gr = Graphics.FromImage(new Bitmap(1000, 1000));
    Rectangle rect = new Rectangle(50, 50, imgGood.Width, imgGood.Height); // where to draw
    gr.DrawImage(imgGood, rect);

Here imgGood can be any Image object - Bitmap, Metafile, or anything else that inherits from Image!

console.log(typeof(timeofday)) // for testing will log number
function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)
    var pos = time.indexOf('.');
    var hrs = time.substr(1, pos - 1);
    var min = (time.substr(pos, 2)) * 60;

    if (hrs > 11) {
        hrs = (hrs - 12) + ":" + min + " PM";
    } else {
        hrs += ":" + min + " AM";
    }
    return hrs;
}
 // "" for typecasting to string
 document.getElementById("oset").innerHTML = timeD2C(""+timeofday);

Solution 2

use toString() to convert to string

document.getElementById("oset").innerHTML = timeD2C(timeofday.toString());

The original question says clear() cannot be used. This does not apply to that situation. I'm adding my working example here as this SO post was one of the first Google results for clearing an input before entering a value.

For input where here is no additional restriction I'm including a browser agnostic method for Selenium using NodeJS. This snippet is part of a common library I import with var test = require( 'common' ); in my test scripts. It is for a standard node module.exports definition.

when_id_exists_type : function( id, value ) {
driver.wait( webdriver.until.elementLocated( webdriver.By.id( id ) ) , 3000 )
    .then( function() {
        var el = driver.findElement( webdriver.By.id( id ) );
        el.click();
        el.clear();
        el.sendKeys( value );
    });
},

Find the element, click it, clear it, then send the keys.

Your code isn't working, because the hidden attibute is not supported in versions of IE before v11

If you need to support IE before version 11, add a CSS style to hide when the hidden attribute is present:

See jQuery.scroll(). You can bind this to the window element to get your desired event hook.

On scroll, then simply check your scroll position:

    // display add
  }
});

http://bloglitb.blogspot.com/2010/07/access-to-private-members-thats-easy.html

this guy's blog shows you how to do it using templates. With some modifications, you can adapt this method to access a private data member, although I found it tricky despite having 10+ years experience.

I wanted to point out like everyone else, that there is an extremely few number of cases where doing this is legitimate. However, I want to point out one: I was writing unit tests for a software suite. A federal regulatory agency requires every single line of code to be exercised and tested, without modifying the original code. Due to (IMHO) poor design, a static constant was in the 'private' section, but I needed to use it in the unit test. So the method seemed to me like the best way to do it.

I'm sure the way could be simplified, and I'm sure there are other ways. I'm not posting this for the OP, since it's been 5 months, but hopefully this will be useful to some future googler.

For me I solved it by deleting the file of php_errors.txt in the relative folder. Then the file is created automatically again when the code runs next time, and with the errors printed this time.

Note that URI encoding is good for the query part, it's not good for the domain. The domain gets encoded using punycode. You need a library like URI.js to convert between a URI and IRI (Internationalized Resource Identifier).

This is correct if you plan on using the string later as a query string:

> encodeURIComponent("http://examplé.org/rosé?rosé=rosé")
'http%3A%2F%2Fexampl%C3%A9.org%2Fros%C3%A9%3Fros%C3%A9%3Dros%C3%A9'

If you don't want ASCII characters like /, : and ? to be escaped, use encodeURI instead:

> encodeURI("http://examplé.org/rosé?rosé=rosé")
'http://exampl%C3%A9.org/ros%C3%A9?ros%C3%A9=ros%C3%A9'

However, for other use-cases, you might need uri-js instead:

> var URI = require("uri-js");
undefined
> URI.serialize(URI.parse("http://examplé.org/rosé?rosé=rosé"))
'http://xn--exampl-gva.org/ros%C3%A9?ros%C3%A9=ros%C3%A9'

.htaccess php_value is working only if you use PHP Server API as module of Web server Apache. Use IfModule syntax:

# PHP 5, Apache 1 and 2.
<IfModule mod_php5.c>
    php_value error_reporting 30711
</IfModule>

If you use PHP Server API CGI/FastCGI use

ini_set('error_reporting', 30711);

or

error_reporting(E_ALL & ~E_STRICT & ~E_NOTICE);

in your PHP code, or PHP configuration files .user.ini | php.ini modification:

error_reporting = E_ALL & ~E_STRICT & ~E_NOTICE

on your virtual host, server level.

You need to use the proper git URL:

pip install git+https://github.com/jkbr/httpie.git#egg=httpie

Also see the VCS Support section of the pip documentation.

Don’t forget to include the egg=<projectname> part to explicitly name the project; this way pip can track metadata for it without having to have run the setup.py script.

Depending on your platform you can use: sqlite3 file_name.db from the terminal. .tables will list the tables, .schema is full layout. SQLite commands like: select * from table_name; and such will print out the full contents. Type: ".exit" to exit. No need to download a GUI application.Use a semi-colon if you want it to execute a single command. Decent SQLite usage tutorial http://www.thegeekstuff.com/2012/09/sqlite-command-examples/

Here is a very easy way of doing that

 $(function () {
    $(".glyphicon").unbind('click');
    $(".glyphicon").click(function (e) {
        $(this).toggleClass("glyphicon glyphicon-chevron-up glyphicon glyphicon-chevron-down");
});

Hope this helps :D

As we read in the previous comments this error is occurring because the current SDK version is incompatible with the newest Java versions: 9 and 10.

So, to solve it, you can downgrade your java version to Java 8, or as a workaround, you can export the following option on your terminal:

Linux:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Windows:

set JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

If this does not work try to exports the java.xml.bind instead.

Linux:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.xml.bind'

Windows:

set JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.xml.bind'

This will solve this error for the sdkmanager

And to make it saved permanently you can export the JAVA_OPTS in your profile file on Linux (.zshrc, .bashrc and etc.) or add it as an environment variable permanently on Windows.

ps. This doesn't work for Java 11/11+, which doesn't have Java EE modules. For this option is a good idea, downgrade your Java version or wait for a Flutter update.

Ref: JDK 11: End of the road for Java EE modules

Just declare a variable like k or m or any other you want, now just add this piece of code at the end of your program

k=input("press close to exit") 

Here I just assumed k as variable to pause the program, you can use any variable you like.

The example you are using is wrong. See the man page for easy_setopt. In the example write_data uses its own FILE, *outfile, and not the fp that was specified in CURLOPT_WRITEDATA. That's why closing fp causes problems - it's not even opened.

This is more or less what it should look like (no libcurl available here to test)

#include <stdio.h>
#include <curl/curl.h>
/* For older cURL versions you will also need 
#include <curl/types.h>
#include <curl/easy.h>
*/
#include <string>

size_t write_data(void *ptr, size_t size, size_t nmemb, FILE *stream) {
    size_t written = fwrite(ptr, size, nmemb, stream);
    return written;
}

int main(void) {
    CURL *curl;
    FILE *fp;
    CURLcode res;
    char *url = "http://localhost/aaa.txt";
    char outfilename[FILENAME_MAX] = "C:\\bbb.txt";
    curl = curl_easy_init();
    if (curl) {
        fp = fopen(outfilename,"wb");
        curl_easy_setopt(curl, CURLOPT_URL, url);
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp);
        res = curl_easy_perform(curl);
        /* always cleanup */
        curl_easy_cleanup(curl);
        fclose(fp);
    }
    return 0;
}

Updated: as suggested by @rsethc types.h and easy.h aren't present in current cURL versions anymore.

The compatibility table given in the tensorflow site does not contain specific minor versions for cuda and cuDNN. However, if the specific versions are not met, there will be an error when you try to use tensorflow.

For tensorflow-gpu==1.12.0 and cuda==9.0, the compatible cuDNN version is 7.1.4, which can be downloaded from here after registration.

You can check your cuda version using
nvcc --version

cuDNN version using
cat /usr/include/cudnn.h | grep CUDNN_MAJOR -A 2

tensorflow-gpu version using
pip freeze | grep tensorflow-gpu

UPDATE: Since tensorflow 2.0, has been released, I will share the compatible cuda and cuDNN versions for it as well (for Ubuntu 18.04).

• tensorflow-gpu = 2.0.0
• cuda = 10.0
• cuDNN = 7.6.0

You can use proxytunnel:

proxytunnel -p yourproxy:8080 -d www.google.com:443 -a 7000

and then you can do this:

openssl s_client -connect localhost:7000 -showcerts

Hope this can help you!

I had to do something like this on a version of linux that didn't have the right options compiled into wget. This example is for downloading the memory analysis tool 'guppy'. I'm not sure if it's important or not, but I kept the target file's name the same as the url target name...

Here's what I came up with:

python -c "import requests; r = requests.get('https://pypi.python.org/packages/source/g/guppy/guppy-0.1.10.tar.gz') ; open('guppy-0.1.10.tar.gz' , 'wb').write(r.content)"

That's the one-liner, here's it a little more readable:

import requests
fname = 'guppy-0.1.10.tar.gz'
url = 'https://pypi.python.org/packages/source/g/guppy/' + fname
r = requests.get(url)
open(fname , 'wb').write(r.content)

This worked for downloading a tarball. I was able to extract the package and download it after downloading.

EDIT:

To address a question, here is an implementation with a progress bar printed to STDOUT. There is probably a more portable way to do this without the clint package, but this was tested on my machine and works fine:

#!/usr/bin/env python

from clint.textui import progress
import requests

fname = 'guppy-0.1.10.tar.gz'
url = 'https://pypi.python.org/packages/source/g/guppy/' + fname

r = requests.get(url, stream=True)
with open(fname, 'wb') as f:
    total_length = int(r.headers.get('content-length'))
    for chunk in progress.bar(r.iter_content(chunk_size=1024), expected_size=(total_length/1024) + 1): 
        if chunk:
            f.write(chunk)
            f.flush()

The basic advantage of using enum class over normal enums is that you may have same enum variables for 2 different enums and still can resolve them(which has been mentioned as type safe by OP)

For eg:

enum class Color1 { red, green, blue };    //this will compile
enum class Color2 { red, green, blue };

enum Color1 { red, green, blue };    //this will not compile 
enum Color2 { red, green, blue };

As for the basic enums, compiler will not be able to distinguish whether red is refering to the type Color1 or Color2 as in hte below statement.

enum Color1 { red, green, blue };   
enum Color2 { red, green, blue };
int x = red;    //Compile time error(which red are you refering to??)

In idlelib.PyShell module, root variable of type Tk is defined to be global

At the end of PyShell.main() function it calls root.mainloop() function which is an infinite loop and it runs till the loop is interrupted by root.quit() function. Hence, root.quit() will only interrupt the execution of mainloop

In order to destroy all widgets pertaining to that idlelib window, root.destroy() needs to be called, which is the last line of idlelib.PyShell.main() function.

Important Edit: This answer is outdated. Since writing it, the Visibility API (mdn, example, spec) has been introduced. It is the better way to solve this problem.

var focused = true;

window.onfocus = function() {
    focused = true;
};
window.onblur = function() {
    focused = false;
};

AFAIK, focus and blur are all supported on...everything. (see http://www.quirksmode.org/dom/events/index.html )

For strings containing   I've had to double-decode the string. First decode would turn it into the second pass would correctly decode it to the expected character.

None of the above worked for me. what worked for me is to go to File -> Invalidate Caches / Restart

Syntax:

kill -9 $(lsof -t -i:portnumber)

Example: To kill the process running at port 4200, run following command

kill -9 $(lsof -t -i:4200)

Tested in Ubuntu.

private void buttonNextForm(object sender, EventArgs e)
{
    NextForm nf = new NextForm();//Object of the form that you want to open
    this.hide();//Hide cirrent form.
    nf.ShowModel();//Display the next form window
    this.Close();//While closing the NextForm, control will come again and will close this form as well
}

^\d+$, which is "start of string", "1 or more digits", "end of string" in English.

A super key is any combination of columns that uniquely identifies a row in a table. A candidate key is a super key which cannot have any columns removed from it without losing the unique identification property. This property is sometimes known as minimality or (better) irreducibility.

A super key ? a primary key in general. The primary key is simply a candidate key chosen to be the main key. However, in dependency theory, candidate keys are important and the primary key is not more important than any of the other candidate keys. Non-primary candidate keys are also known as alternative keys.

Consider this table of Elements:

CREATE TABLE elements
(
    atomic_number   INTEGER NOT NULL PRIMARY KEY
                    CHECK (atomic_number > 0 AND atomic_number < 120),
    symbol          CHAR(3) NOT NULL UNIQUE,
    name            CHAR(20) NOT NULL UNIQUE,
    atomic_weight   DECIMAL(8,4) NOT NULL,
    period          SMALLINT NOT NULL
                    CHECK (period BETWEEN 1 AND 7),
    group           CHAR(2) NOT NULL
                    -- 'L' for Lanthanoids, 'A' for Actinoids
                    CHECK (group IN ('1', '2', 'L', 'A', '3', '4', '5', '6',
                                     '7', '8', '9', '10', '11', '12', '13',
                                     '14', '15', '16', '17', '18')),
    stable          CHAR(1) DEFAULT 'Y' NOT NULL
                    CHECK (stable IN ('Y', 'N'))
);

It has three unique identifiers - atomic number, element name, and symbol. Each of these, therefore, is a candidate key. Further, unless you are dealing with a table that can only ever hold one row of data (in which case the empty set (of columns) is a candidate key), you cannot have a smaller-than-one-column candidate key, so the candidate keys are irreducible.

Consider a key made up of { atomic number, element name, symbol }. If you supply a consistent set of values for these three fields (say { 6, Carbon, C }), then you uniquely identify the entry for an element - Carbon. However, this is very much a super key that is not a candidate key because it is not irreducible; you can eliminate any two of the three fields without losing the unique identification property.

As another example, consider a key made up of { atomic number, period, group }. Again, this is a unique identifier for a row; { 6, 2, 14 } identifies Carbon (again). If it were not for the Lanthanoids and Actinoids, then the combination of { period, group } would be unique, but because of them, it is not. However, as before, atomic number on its own is sufficient to uniquely identify an element, so this is a super key and not a candidate key.

Just like the & and && operator, the double Operator is a "short-circuit" operator.

For example:

if(condition1 || condition2 || condition3)

If condition1 is true, condition 2 and 3 will NOT be checked.

if(condition1 | condition2 | condition3)

This will check conditions 2 and 3, even if 1 is already true. As your conditions can be quite expensive functions, you can get a good performance boost by using them.

There is one big caveat, NullReferences or similar problems. For example:

if(class != null && class.someVar < 20)

If class is null, the if-statement will stop after class != null is false. If you only use &, it will try to check class.someVar and you get a nice NullReferenceException. With the Or-Operator that may not be that much of a trap as it's unlikely that you trigger something bad, but it's something to keep in mind.

No one ever uses the single & or | operators though, unless you have a design where each condition is a function that HAS to be executed. Sounds like a design smell, but sometimes (rarely) it's a clean way to do stuff. The & operator does "run these 3 functions, and if one of them returns false, execute the else block", while the | does "only run the else block if none return false" - can be useful, but as said, often it's a design smell.

There is a Second use of the | and & operator though: Bitwise Operations.

Something throws an exception of type std::bad_alloc, indicating that you ran out of memory. This exception is propagated through until main, where it "falls off" your program and causes the error message you see.

Since nobody here knows what "RectInvoice", "rectInvoiceVector", "vect", "im" and so on are, we cannot tell you what exactly causes the out-of-memory condition. You didn't even post your real code, because w h looks like a syntax error.

If your pdf is text-based and not a scanned document (i.e. if you can click and drag to select text in your table in a PDF viewer), then you can use the module camelot-py with

import camelot
tables = camelot.read_pdf('foo.pdf')

You then can choose how you want to save the tables (as csv, json, excel, html, sqlite), and whether the output should be compressed in a ZIP archive.

tables.export('foo.csv', f='csv', compress=False)

Edit: tabula-py appears roughly 6 times faster than camelot-py so that should be used instead.

import camelot
import cProfile
import pstats
import tabula

cmd_tabula = "tabula.read_pdf('table.pdf', pages='1', lattice=True)"
prof_tabula = cProfile.Profile().run(cmd_tabula)
time_tabula = pstats.Stats(prof_tabula).total_tt

cmd_camelot = "camelot.read_pdf('table.pdf', pages='1', flavor='lattice')"
prof_camelot = cProfile.Profile().run(cmd_camelot)
time_camelot = pstats.Stats(prof_camelot).total_tt

print(time_tabula, time_camelot, time_camelot/time_tabula)

gave

I encountered the same error in GitHub Actions. Adding sudo solved the issue.

sudo gem install bundler

Quick and easy with no external tools, works well as long as the two sheets you are comparing are similar:

• Create a third spreadsheet
• Type =if(Sheet1!A1 <> Sheet2!A1, "X", "") in the top left cell (or equivalent: click on the actual cells to automatically have the references inserted into the formula)
• Ctrl+C (copy), Ctrl+A (select all), Ctrl+V (paste) to fill the sheet.

If the sheets are similar, this spreadsheet will be empty except for a few cells with X in them, highlighting the differences. Unzoom to 40% to quickly see what is different.

Revisiting @brent-nash contribution, we could use modulus function instead of subtractions and use String.format method for the result string:

  /**
   * Convert a millisecond duration to a string format
   * 
   * @param millis A duration to convert to a string form
   * @return A string of the form "X Days Y Hours Z Minutes A Seconds B Milliseconds".
   */
   public static String getDurationBreakdown(long millis) {
       if (millis < 0) {
          throw new IllegalArgumentException("Duration must be greater than zero!");
       }

       long days = TimeUnit.MILLISECONDS.toDays(millis);
       long hours = TimeUnit.MILLISECONDS.toHours(millis) % 24;
       long minutes = TimeUnit.MILLISECONDS.toMinutes(millis) % 60;
       long seconds = TimeUnit.MILLISECONDS.toSeconds(millis) % 60;
       long milliseconds = millis % 1000;

       return String.format("%d Days %d Hours %d Minutes %d Seconds %d Milliseconds",
                            days, hours, minutes, seconds, milliseconds);
   }

You can put an <a> element inside the <div> and set it to display: block and height: 100%.

The thing to watch out for when writing C++ dlls is name mangling. If you want interoperability between C and C++, you'd be better off by exporting non-mangled C-style functions from within the dll.

You have two options to use a dll

• Either use a lib file to link the symbols -- compile time dynamic linking
• Use LoadLibrary() or some suitable function to load the library, retrieve a function pointer (GetProcAddress) and call it -- runtime dynamic linking

Exporting classes will not work if you follow the second method though.

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

Here is another method, where you don't have to duplicate the contents of the view:

IF (NOT EXISTS (SELECT 1 FROM sys.views WHERE name = 'data_VVV'))
BEGIN
    EXECUTE('CREATE VIEW data_VVVV as SELECT 1 as t');
END;

GO

ALTER VIEW data_VVVV AS 
    SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A ;

The first checks for the existence of the view (there are other ways to do this). If it doesn't exist, then create it with something simple and dumb. If it does, then just move on to the alter view statement.

If you don't want to make Broadcast Receiver then simple try

WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo;

wifiInfo = wifiManager.getConnectionInfo();
if (wifiInfo.getSupplicantState() == SupplicantState.COMPLETED) {
    ssid = wifiInfo.getSSID();
}

Remember every time user disconnect or connect to new SSID or any wifi state change then you need to initialize WifiInfo i.e wifiInfo = wifiManager.getConnectionInfo();

I had this error after doing some git merge from a branch where my classes extended a new interface. It was enough to Refresh (F5) the File-Tree in the Package Explorer frame of Eclipse.

It seems that Eclipse did not update everything properly and so the classes were extending a non-existing-yet interface. After refresh, all errors disappeared.

Terminology

From quirksmode.org:

Event capturing

When you use event capturing

               | |
---------------| |-----------------
| element1     | |                |
|   -----------| |-----------     |
|   |element2  \ /          |     |
|   -------------------------     |
|        Event CAPTURING          |
-----------------------------------

the event handler of element1 fires first, the event handler of element2 fires last.

Event bubbling

When you use event bubbling

               / \
---------------| |-----------------
| element1     | |                |
|   -----------| |-----------     |
|   |element2  | |          |     |
|   -------------------------     |
|        Event BUBBLING           |
-----------------------------------

the event handler of element2 fires first, the event handler of element1 fires last.

Any event taking place in the W3C event model is first captured until it reaches the target element and then bubbles up again.

                 | |  / \
-----------------| |--| |-----------------
| element1       | |  | |                |

Interface

From w3.org, for event capture:

If the capturing EventListener wishes to prevent further processing of the event from occurring it may call the stopPropagation method of the Event interface. This will prevent further dispatch of the event, although additional EventListeners registered at the same hierarchy level will still receive the event. Once an event's stopPropagation method has been called, further calls to that method have no additional effect. If no additional capturers exist and stopPropagation has not been called, the event triggers the appropriate EventListeners on the target itself.

For event bubbling:

Any event handler may choose to prevent further event propagation by calling the stopPropagation method of the Event interface. If any EventListener calls this method, all additional EventListeners on the current EventTarget will be triggered but bubbling will cease at that level. Only one call to stopPropagation is required to prevent further bubbling.

For event cancelation:

Cancelation is accomplished by calling the Event's preventDefault method. If one or more EventListeners call preventDefault during any phase of event flow the default action will be canceled.

Examples

In the following examples, a click on the hyperlink in the web browser triggers the event's flow (the event listeners are executed) and the event target's default action (a new tab is opened).

HTML:

<div id="a">
  <a id="b" href="http://www.google.com/" target="_blank">Google</a>
</div>
<p id="c"></p>

JavaScript:

var el = document.getElementById("c");

function capturingOnClick1(ev) {
    el.innerHTML += "DIV event capture<br>";
}

function capturingOnClick2(ev) {
    el.innerHTML += "A event capture<br>";
}

function bubblingOnClick1(ev) {
    el.innerHTML += "DIV event bubbling<br>";
}

function bubblingOnClick2(ev) {
    el.innerHTML += "A event bubbling<br>";
}

// The 3rd parameter useCapture makes the event listener capturing (false by default)
document.getElementById("a").addEventListener("click", capturingOnClick1, true);
document.getElementById("b").addEventListener("click", capturingOnClick2, true);
document.getElementById("a").addEventListener("click", bubblingOnClick1, false);
document.getElementById("b").addEventListener("click", bubblingOnClick2, false);

Example 1: it results in the output

DIV event capture
A event capture
A event bubbling
DIV event bubbling

Example 2: adding stopPropagation() to the function

function capturingOnClick1(ev) {
    el.innerHTML += "DIV event capture<br>";
    ev.stopPropagation();
}

results in the output

DIV event capture

The event listener prevented further downward and upward propagation of the event. However it did not prevent the default action (a new tab opening).

Example 3: adding stopPropagation() to the function

function capturingOnClick2(ev) {
    el.innerHTML += "A event capture<br>";
    ev.stopPropagation();
}

or the function

function bubblingOnClick2(ev) {
    el.innerHTML += "A event bubbling<br>";
    ev.stopPropagation();
}

results in the output

DIV event capture
A event capture
A event bubbling

This is because both event listeners are registered on the same event target. The event listeners prevented further upward propagation of the event. However they did not prevent the default action (a new tab opening).

Example 4: adding preventDefault() to any function, for instance

function capturingOnClick1(ev) {
    el.innerHTML += "DIV event capture<br>";
    ev.preventDefault();
}

prevents a new tab from opening.

I was hitting this issue while running Tomcat inside of a Docker container. To fix this make sure you add the '-p 8000:8000' argument in your docker run command to expose this port to your local machine. You will of course need the setenv.sh file in your ${CATALINA_HOME}/bin/ within your container as well.

WebRequest being abstract (and since any inheriting class must override the Headers property).. which concrete WebRequest are you using ? In other words, how do you get that WebRequest object to beign with ?

ehr.. mnour answer made me realize that the error message you were getting is actually spot on: it's telling you that the header you are trying to add already exist and you should then modify its value using the appropriate property (the indexer, for instance), instead of trying to add it again. That's probably all you were looking for.

Other classes inheriting from WebRequest might have even better properties wrapping certain headers; See this post for instance.

One way I found after some struggling is creating a function which gets data_plot matrix, file name and order as parameter to create boxplots from the given data in the ordered figure (different orders = different figures) and save it under the given file_name.

def plotFigure(data_plot,file_name,order):
    fig = plt.figure(order, figsize=(9, 6))

If you want to change your 'sa' password with SQL Server Management Studio, here are the steps:

1. Login using Windows Authentication and ".\SQLExpress" as Server Name

2. Change server authentication mode - Right click on root, choose Properties, from Security tab select "SQL Server and Windows Authentication mode", click OK

3. Set sa password - Navigate to Security > Logins > sa, right click on it, choose Properties, from General tab set the Password (don't close the window)

4. Grant permission - Go to Status tab, make sure the Grant and Enabled radiobuttons are chosen, click OK

5. Restart SQLEXPRESS service from your local services (Window+R > services.msc)

readline is for string.. just use read

You can pass PHP arrays to JavaScript using json_encode PHP function.

<?php
    $phpArray = array(
        0 => "Mon", 
        1 => "Tue", 
        2 => "Wed", 
        3 => "Thu",
        4 => "Fri", 
        5 => "Sat",
        6 => "Sun",
    )
?>

<script type="text/javascript">

    var jArray = <?php echo json_encode($phpArray); ?>;

    for(var i=0; i<jArray.length; i++){
        alert(jArray[i]);
    }

 </script>

If you already have a file package.json in the project and it contains grunt in dependency,

  "devDependencies": {
    "grunt": "~0.4.0",

Then you can run npm install to resolve the issue

I've just found this solution:

if(@getimagesize($remoteImageURL)){
    //image exists!
}else{
    //image does not exist.
}

You need to use the ajax-cross-origin plugin: http://www.ajax-cross-origin.com/

Just add the option crossOrigin: true

$.ajax({
    crossOrigin: true,
    url: url,
    success: function(data) {
        console.log(data);
    }
});

It means you're trying to call something that isn't a function

const foo = 'string'
foo() // error

If you guys are generating your stylesheets with LESS/SASS and are importing Bootstrap there, I've found that overriding the @navbar-height variable lets your set the height of the navbar, which is originally defined in the variables.less file.

You need to escape the dot if you want to split on a literal dot:

String extensionRemoved = filename.split("\\.")[0];

Otherwise you are splitting on the regex ., which means "any character".
Note the double backslash needed to create a single backslash in the regex.

You're getting an ArrayIndexOutOfBoundsException because your input string is just a dot, ie ".", which is an edge case that produces an empty array when split on dot; split(regex) removes all trailing blanks from the result, but since splitting a dot on a dot leaves only two blanks, after trailing blanks are removed you're left with an empty array.

To avoid getting an ArrayIndexOutOfBoundsException for this edge case, use the overloaded version of split(regex, limit), which has a second parameter that is the size limit for the resulting array. When limit is negative, the behaviour of removing trailing blanks from the resulting array is disabled:

".".split("\\.", -1) // returns an array of two blanks, ie ["", ""]

ie, when filename is just a dot ".", calling filename.split("\\.", -1)[0] will return a blank, but calling filename.split("\\.")[0] will throw an ArrayIndexOutOfBoundsException.

I realize that this is quite and old question, but I have a 'stupid' solution to a similar problem which maybe could help someone.

I experienced the same problem with a text box which shown as selected (by the Focus method in JQuery), but did not take the cursor in.

The fact is that I had the Debugger window open to see what is happening and THAT window was stealing the focus. The solution is banally simple: just close the Debugger and everything is fine...1 hour spent in testing!

This works with abitrarily nested lists. It can be easily extended to work with other kinds of iterables.

def flatten(seq):
    """list -> list                                                                                                                                                                           
    return a flattend list from an abitrarily nested list                                                                                                                                     
    """
    if not seq:
        return []
    if not isinstance(seq[0], list):
        return [seq[0]] + flatten(seq[1:])
    return flatten(seq[0]) + flatten(seq[1:])

Sample run

>>> flatten([1, [2, 3], [[[4, 5, 6], 7], [[8]]], 9])
[1, 2, 3, 4, 5, 6, 7, 8, 9]

Here's A generic VBA Array To Range function that writes an array to the sheet in a single 'hit' to the sheet. This is much faster than writing the data into the sheet one cell at a time in loops for the rows and columns... However, there's some housekeeping to do, as you must specify the size of the target range correctly.

This 'housekeeping' looks like a lot of work and it's probably rather slow: but this is 'last mile' code to write to the sheet, and everything is faster than writing to the worksheet. Or at least, so much faster that it's effectively instantaneous, compared with a read or write to the worksheet, even in VBA, and you should do everything you possibly can in code before you hit the sheet.

A major component of this is error-trapping that I used to see turning up everywhere . I hate repetitive coding: I've coded it all here, and - hopefully - you'll never have to write it again.

A VBA 'Array to Range' function

Public Sub ArrayToRange(rngTarget As Excel.Range, InputArray As Variant)
' Write an array to an Excel range in a single 'hit' to the sheet
' InputArray must be a 2-Dimensional structure of the form Variant(Rows, Columns)

' The target range is resized automatically to the dimensions of the array, with
' the top left cell used as the start point.

' This subroutine saves repetitive coding for a common VBA and Excel task.

' If you think you won't need the code that works around common errors (long strings
' and objects in the array, etc) then feel free to comment them out.

You will need the source for ArrayDimensions:

This API declaration is required in the module header:

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
                   (Destination As Any, _
                    Source As Any, _
                    ByVal Length As Long)

...And here's the function itself:

Private Function ArrayDimensions(arr As Variant) As Integer
  '-----------------------------------------------------------------
  ' will return:
  ' -1 if not an array
  ' 0  if an un-dimmed array
  ' 1  or more indicating the number of dimensions of a dimmed array
  '-----------------------------------------------------------------

  Dim ptr As Long
  Dim vType As Integer

  Const VT_BYREF = &H4000&

  'get the real VarType of the argument
  'this is similar to VarType(), but returns also the VT_BYREF bit
  CopyMemory vType, arr, 2

  'exit if not an array
  If (vType And vbArray) = 0 Then
    ArrayDimensions = -1
    Exit Function
  End If

  'get the address of the SAFEARRAY descriptor
  'this is stored in the second half of the
  'Variant parameter that has received the array
  CopyMemory ptr, ByVal VarPtr(arr) + 8, 4

  'see whether the routine was passed a Variant
  'that contains an array, rather than directly an array
  'in the former case ptr already points to the SA structure.
  'Thanks to Monte Hansen for this fix

  If (vType And VT_BYREF) Then
    ' ptr is a pointer to a pointer
    CopyMemory ptr, ByVal ptr, 4
  End If

  'get the address of the SAFEARRAY structure
  'this is stored in the descriptor

  'get the first word of the SAFEARRAY structure
  'which holds the number of dimensions
  '...but first check that saAddr is non-zero, otherwise
  'this routine bombs when the array is uninitialized

  If ptr Then
    CopyMemory ArrayDimensions, ByVal ptr, 2
  End If

End Function

Also: I would advise you to keep that declaration private. If you must make it a public Sub in another module, insert the Option Private Module statement in the module header. You really don't want your users calling any function with CopyMemoryoperations and pointer arithmetic.

ntd's anwser didn't solve my problem. For those in same situation, here is how I finally handled this error: Just utf8_encode each of your results.

while($row = mysql_fetch_assoc($result)){
    $rows[] = array_map('utf8_encode', $row);
}

Hope it helps!

Try this solution if the Reset Password option (of SQL Developer) did not work:

Step 1: Open Run SQL Command Line (from the start menu, which comes with SQL Developer installation package)

Step 2: Run the following commands:

Note: If password has already expired, Changing password for <user> option will automatically come.

The only safe way to protect your code is not giving it away. With client deployment, there is no avoiding the client having access to the code.

So the short answer is: You can't do it

The longer answer is considering flash or Silverlight. Although I believe silverlight will gladly give away it's secrets with reflector running on the client.

I'm not sure if something simular exists with the flash platform.

in my case :
I/Ads: Ad failed to load : Account not approved yet.

but you need to implement the listener for knowing the error

First import the listener : import com.google.android.gms.ads.AdListener;
Second create variable : private final String TAG2 = com.ringtones.splash.class.getSimpleName();

            mAdView.setAdListener(new AdListener() {
            @Override
            public void onAdLoaded() {Log.d(TAG2, "google banner ad loaded"); }
            @Override
            public void onAdFailedToLoad(LoadAdError adError) {Log.d(TAG2, "google banner ad failed to load : "+ adError.getMessage());}
            @Override
            public void onAdOpened() {Log.d(TAG2, "google banner ad opened");}
            @Override
            public void onAdClicked() {Log.d(TAG2, "google banner ad clicked");}
            @Override
            public void onAdLeftApplication() {Log.d(TAG2, "google banner ad left application");}
            @Override
            public void onAdClosed() {Log.d(TAG2, "google banner ad closed");}
        });

Here are three different ways to do it:

Here's a working Demo in Fiddle Of All Three

Validation:

You can use native bootstrap validation states (No Custom CSS!):

<div class="form-group has-feedback">
    <label class="control-label" for="inputSuccess2">Name</label>
    <input type="text" class="form-control" id="inputSuccess2"/>
    <span class="glyphicon glyphicon-search form-control-feedback"></span>
</div>

For a full discussion, see my answer to Add a Bootstrap Glyphicon to Input Box

Input Group:

You can use the .input-group class like this:

<div class="input-group">
    <input type="text" class="form-control"/>
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

For a full discussion, see my answer to adding Twitter Bootstrap icon to Input box

Unstyled Input Group:

You can still use .input-group for positioning but just override the default styling to make the two elements appear separate.

Use a normal input group but add the class input-group-unstyled:

<div class="input-group input-group-unstyled">
    <input type="text" class="form-control" />
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

Then change the styling with the following css:

.input-group.input-group-unstyled input.form-control {
    -webkit-border-radius: 4px;
       -moz-border-radius: 4px;
            border-radius: 4px;
}
.input-group-unstyled .input-group-addon {
    border-radius: 4px;
    border: 0px;
    background-color: transparent;
}

Also, these solutions work for any input size

Use pg_dump, and later psql or pg_restore - depending whether you choose -Fp or -Fc options to pg_dump.

Example of usage:

ssh production
pg_dump -C -Fp -f dump.sql -U postgres some_database_name
scp dump.sql development:
rm dump.sql
ssh development
psql -U postgres -f dump.sql

Edit #3:

The Navigation Drawer pattern is officially described in the Android documentation!

Check out the following links:

• Design docs can be found here.
• Developer docs can be found here.

Edit #2:

Roman Nurik (an Android design engineer at Google) has confirmed that the recommended behavior is to not move the Action Bar when opening the drawer (like the YouTube app). See this Google+ post.

Edit #1:

I answered this question a while ago, but I'm back to re-emphasize that Prixing has the best fly-out menu out there... by far. It's absolutely beautiful, perfectly smooth, and it puts Facebook, Google+, and YouTube to shame. EverNote is pretty good too... but still not as perfect as Prixing. Check out this series of posts on how the flyout menu was implemented (from none other than the head developer at Prixing himself!).

Original Answer:

Adam Powell and Richard Fulcher talk about this at 49:47 - 52:50 in the Google I/O talk titled "Navigation in Android".

To summarize their answer, as of the date of this posting the slide out navigation menu is not officially part of the Android application design standard. As you have probably discovered, there's currently no native support for this feature, but there was talk about making this an addition to an upcoming revision of the support package.

With regards to the YouTube and G+ apps, it does seem odd that they behave differently. My best guess is that the reason the YouTube app fixes the position of the action bar is,

1. One of the most important navigational options for users using the YouTube app is search, which is performed in the SearchView in the action bar. It would make sense to make the action bar static in this regard, since it would allow the user to always have the option to search for new videos.

2. The G+ app uses a ViewPager to display its content, so making the pull out menu specific to the layout content (i.e. everything under the action bar) wouldn't make much sense. Swiping is supposed to provide a means of navigating between pages, not a means of global navigation. This might be why they decided to do it differently in the G+ app than they did in the YouTube app.

   On another note, check out the Google Play app for another version of the "pull out menu" (when you are at the left most page, swipe left and a pull out, "half-page" menu will appear).

You're right in that this isn't very consistent behavior, but it doesn't seem like there is a 100% consensus within the Android team on how this behavior should be implemented yet. I wouldn't be surprised if in the future the apps are updated so that the navigation in both apps are identical (they seemed very keen on making navigation consistent across all Google-made apps in the talk).

you can use the following code for getting the brand name and brand model of the device.

 String brand = Build.BRAND; // for getting BrandName
 String model = Build.MODEL; // for getting Model of the device

You might be better off if you just don't use nested classes. If you must nest, try this:

x = 1
class OuterClass:
    outer_var = x
    class InnerClass:
        inner_var = x

Or declare both classes before nesting them:

class OuterClass:
    outer_var = 1

class InnerClass:
    inner_var = OuterClass.outer_var

OuterClass.InnerClass = InnerClass

(After this you can del InnerClass if you need to.)

This article describes how to get information about locked MySQL resources. mysqladmin debug might also be of some use.

Axivion Bauhaus Suite is a static analysis tool that works with C# (as well as C, C++ and Java).

It provides the following capabilities:

• Software Architecture Visualization (inlcuding dependencies)
• Enforcement of architectural rules e.g. layering, subsystems, calling rules
• Clone Detection - highlighting copy and pasted (and modified code)
• Dead Code Detection
• Cycle Detection
• Software Metrics
• Code Style Checks

These features can be run on a one-off basis or as part of a Continuous Integration process. Issues can be highlighted on a per project basis or per developer basis when the system is integrated with a source code control system.

From this answer, you get a readable and efficient representation: https://stackoverflow.com/a/65939892/3746632

The constraint could be removed with syntax:

ALTER TABLE

As of MySQL 8.0.19, ALTER TABLE permits more general (and SQL standard) syntax for dropping and altering existing constraints of any type, where the constraint type is determined from the constraint name: ALTER TABLE tbl_name DROP CONSTRAINT symbol;

Example:

CREATE TABLE tab(id INT, CONSTRAINT unq_tab_id UNIQUE(id));

-- checking constraint name if autogenerated
SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE TABLE_NAME = 'tab';

-- dropping constraint
ALTER TABLE tab DROP CONSTRAINT unq_tab_id;

db<>fiddle demo

If you are using bootstrap, then:

<div class="pull-right"></div>

When creating a PWA, a service worker used on an non https server also generates this error.

^{Assuming you actually mean timestamp because there is no datetime in Postgres}

Cast the timestamp column to a date, that will remove the time part:

select *
from the_table
where the_timestamp_column::date = date '2015-07-15';

This will return all rows from July, 15th.

Note that the above will not use an index on the_timestamp_column. If performance is critical, you need to either create an index on that expression or use a range condition:

select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
  and the_timestamp_column < timestamp '2015-07-16 00:00:00';

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

It's possible to remove the workspace in Eclipse without much complications. The options are available under Preferences->General->Startup and Shutdown->Workspaces.

Note that this does not actually delete the files from the system, it simply removes it from the list of suggested workspaces. It changes the org.eclipse.ui.ide.prefs file in Jon's answer from within Eclipse.

You can use the Select parameter and use COUNT in the request. It "returns the number of matching items, rather than the matching items themselves". Important, as brought up by Saumitra R. Bhave in a comment, "If the size of the Query result set is larger than 1 MB, then ScannedCount and Count will represent only a partial count of the total items. You will need to perform multiple Query operations in order to retrieve all of the results".

I'm Not familiar with PHP but here is how you could use it with Java. And then instead of using Count (which I am guessing is a function in PHP) on the 'Items' you can use the Count value from the response - $result['Count']:

final String week = "whatever";
final Integer myPoint = 1337;
Condition weekCondition = new Condition()
        .withComparisonOperator(ComparisonOperator.EQ)
        .withAttributeValueList(new AttributeValue().withS(week));
Condition myPointCondition = new Condition()
        .withComparisonOperator(ComparisonOperator.GE)
        .withAttributeValueList(new AttributeValue().withN(myPoint.toString()))

Map<String, Condition> keyConditions = new HashMap<>();
keyConditions.put("week", weekCondition);
keyConditions.put("point", myPointCondition);

QueryRequest request = new QueryRequest("game_table");
request.setIndexName("week-point-index");
request.setSelect(Select.COUNT);
request.setKeyConditions(keyConditions);

QueryResult result = dynamoDBClient.query(request);
Integer count = result.getCount();

If you don't need to emulate the WHERE clause, you can use a DescribeTable request and use the resulting item count to get an estimate.

The number of items in the specified table. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

Also, an important note from the documentation as noted by Saumitra R. Bhave in the comments on this answer:

If the size of the Query result set is larger than 1 MB, ScannedCount and Count represent only a partial count of the total items. You need to perform multiple Query operations to retrieve all the results (see Paginating Table Query Results).

In case you want store the value:

Pair.of<List<>, List<>> output = opt.map(details -> Pair.of(details.a, details.b))).orElseGet(() -> Pair.of(Collections.emptyList(), Collections.emptyList()));

 $mail->SMTPOptions = array(
                'ssl' => array(
                    'verify_peer' => false,
                    'verify_peer_name' => false,
                    'allow_self_signed' => true
                )
            );

While the answers that are already here work well, I found that they were slightly slower than I had hoped for. Instead I used zip4j, which I think is the best solution because of its speed. It also allowed for different options for the amount of compression, which I found useful.

another great and easy way is to have a blind modal in your layout and call it if neccessary.

JS

  var remote_modal = function(url) {
    // reset modal body with a spinner or empty content
    spinner = "<div class='text-center'><i class='fa fa-spinner fa-spin fa-5x fa-fw'></i></div>"

    $("#remote-modal .modal-body").html(spinner)
    $("#remote-modal .modal-body").load(url);
    $("#remote-modal").modal("show");
  }

and your HTML

 <div class='modal fade' id='remote-modal'>
    <div class='modal-dialog modal-lg'>
      <div class='modal-content'>
        <div class='modal-body'></div>
        <div class='modal-footer'>
          <button class='btn btn-default'>Close</button>
        </div>
      </div>
    </div>
  </div>
</body>

now you can simply call remote_modal('/my/url.html') and the content gets displayed inside of the modal

If you are using email password then you should replace it with app password.for setting APP password you need to enable the 2 step authentication before setting password which can be disabled later.

Try TinyXML or IrrXML...Both are lightweight XML parsers ( I'd suggest you to use TinyXML, anyway ).

You need to create folders inside "framework". Please Follow these steps:

cd storage/
mkdir -p framework/{sessions,views,cache}

You also need to set permissions to allow Laravel to write data in this directory.

chmod -R 775 framework
chown -R www-data:www-data framework

There is too much data to be displayed on the screen, therefore a summary is displayed instead.

If you want to output the data anyway (it won't probably fit on a screen and does not look very well):

print paramdata.values

converts the dataframe to its numpy-array matrix representation.

paramdata.columns

stores the respective column names and

paramdata.index

stores the respective index (row names).

The answer of rakensi from Getting path of an R script is the most correct and really brilliant IMHO. Yet, it's still a hack incorporating a dummy function. I'm quoting it here, in order to have it easier found by others.

sourceDir <- getSrcDirectory(function(dummy) {dummy})

This gives the directory of the file where the statement was placed (where the dummy function is defined). It can then be used to set the working direcory and use relative paths e.g.

setwd(sourceDir)
source("other.R")

or to create absolute paths

 source(paste(sourceDir, "/other.R", sep=""))

I do not have an answer to the question of Kornel, but I've a remark about the other script examples. Most of the expression trust implicitly on the toString(), but the Enum.valueOf() expects a value that comes from/matches the Enum.name() property. So one should use e.g.:

<% pageContext.setAttribute("Status_OLD", Status.OLD.name()); %>
...
<c:when test="${someModel.status == Status_OLD}"/>...</c:when>

Look in the setup.py file of the package you are trying to install. If it is an older package it may be importing distutils.core.setup() rather than setuptools.setup().

I ran in to this (in 2015) with a combination of these factors:

1. The Microsoft Visual C++ Compiler for Python 2.7 from http://aka.ms/vcpython27

2. An older package that uses distutils.core.setup()

3. Trying to do python setup.py build rather than using pip.

If you use a recent version of pip, it will force (monkeypatch) the package to use setuptools, even if its setup.py calls for distutils. However, if you are not using pip, and instead are just doing python setup.py build, the build process will use distutils.core.setup(), which does not know about the compiler install location.

Solution

Step 1: Open the appropriate Visual C++ 2008 Command Prompt

Open the Start menu or Start screen, and search for "Visual C++ 2008 32-bit Command Prompt" (if your python is 32-bit) or "Visual C++ 2008 64-bit Command Prompt" (if your python is 64-bit). Run it. The command prompt should say Visual C++ 2008 ... in the title bar.

Step 2: Set environment variables

Set these environment variables in the command prompt you just opened.

SET DISTUTILS_USE_SDK=1
SET MSSdk=1

Step 3: Build and install

cd to the package you want to build, and run python setup.py build, then python setup.py install. If you want to install in to a virtualenv, activate it before you build.
