For reference, the solution is:

UPDATE mysql.user SET host = '10.0.0.%' WHERE host = 'internalfoo' AND user != 'root';
UPDATE mysql.db SET host = '10.0.0.%' WHERE host = 'internalfoo' AND user != 'root';
FLUSH PRIVILEGES;

If you have a Date (or Datetime) column, look at http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_date-format

 SELECT DATE_FORMAT(datecolumn,'%d/%m/%Y') FROM ...

Should do the job for MySQL, for SqlServer I'm sure there is an analog function. If you have a VARCHAR column, you might have at first to convert it to a date, see STR_TO_DATE for MySQL.

You have 2 options for this error:

1. The file you are uploading is too big, which you need to use smaller file.
2. Increase the upload size in php.ini to

upload_max_filesize = 9M; post_max_size = 9M;

Use git push origin master instead.

You have a repository locally and the initial git push is "pushing" to it. It's not necessary to do so (as it is local) and it shows everything as up-to-date. git push origin master specifies a a remote repository (origin) and the branch located there (master).

For more information, check out this resource.

Use comm -13 (requires sorted files):

$ cat file1
one
two
three

$ cat file2
one
two
three
four

$ comm -13 <(sort file1) <(sort file2)
four

You can use a simpler pre-processor trick if you are willing to list your enum entries in an external file.

/* file: errors.def */
/* syntax: ERROR_DEF(name, value) */
ERROR_DEF(ErrorA, 0x1)
ERROR_DEF(ErrorB, 0x2)
ERROR_DEF(ErrorC, 0x4)

Then in a source file, you treat the file like an include file, but you define what you want the ERROR_DEF to do.

enum Errors {
#define ERROR_DEF(x,y) x = y,
#include "errors.def"
#undef ERROR_DEF
};

static inline std::ostream & operator << (std::ostream &o, Errors e) {
    switch (e) {
    #define ERROR_DEF(x,y) case y: return o << #x"[" << y << "]";
    #include "errors.def"
    #undef ERROR_DEF
    default: return o << "unknown[" << e << "]";
    }
}

If you use some source browsing tool (like cscope), you'll have to let it know about the external file.

This is answered in the comments; package-lock.json is a feature in npm v5 and higher. npm shrinkwrap is how you create a lockfile in all versions of npm.

OP I'm with you man. again too, there is nothing wrong with that answer with 300+ up votes, but my opinion is:

1. what is wrong with putting classes into their cozy warm own files individually? I mean this will make things looks much better right? (or someone just like a 1000 line file for all the models)

2. so then, if the first one will be achieved, we have to import import import... import just in each of the model files like man, srsly, a model file, a .d.ts file, why there are so many *s in there? it should just be simple, tidy, and that's it. Why I need imports there? why? C# got namespaces for a reason.

3. And by then, you are literally using "filenames.ts" as identifiers. As identifiers... Come on its 2017 now and we still do that? Ima go back to Mars and sleep for another 1000 years.

So sadly, my answer is: nop, you cannot make the "namespace" thing functional if you do not using all those imports or using those filenames as identifiers (which I think is really silly). Another option is: put all of those dependencies into a box called filenameasidentifier.ts and use

export namespace(or module) boxInBox {} .

wrap them so they wont try to access other classes with same name when they are just simply trying to get a reference from the class sit right on top of them.

You should not think about Hive as a regular RDBMS, Hive is better suited for batch processing over very large sets of immutable data.

The following applies to versions prior to Hive 0.14, see the answer by ashtonium for later versions.

There is no operation supported for deletion or update of a particular record or particular set of records, and to me this is more a sign of a poor schema.

Here is what you can find in the official documentation:

Hadoop is a batch processing system and Hadoop jobs tend to have high latency and
incur substantial overheads in job submission and scheduling. As a result -
latency for Hive queries is generally very high (minutes) even when data sets
involved are very small (say a few hundred megabytes). As a result it cannot be
compared with systems such as Oracle where analyses are conducted on a
significantly smaller amount of data but the analyses proceed much more
iteratively with the response times between iterations being less than a few
minutes. Hive aims to provide acceptable (but not optimal) latency for
interactive data browsing, queries over small data sets or test queries.

Hive is not designed for online transaction processing and does not offer
real-time queries and row level updates. It is best used for batch jobs over
large sets of immutable data (like web logs).

A way to work around this limitation is to use partitions: I don't know what you id corresponds to, but if you're getting different batches of ids separately, you could redesign your table so that it is partitioned by id, and then you would be able to easily drop partitions for the ids you want to get rid of.

One of the Related posts gave me the (simple) answer.

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;
    height: calc(100vh - 10px);
}

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

Enqueue and Dequeue tend to be operations on a queue, a data structure that does exactly what it sounds like it does.

You enqueue items at one end and dequeue at the other, just like a line of people queuing up for tickets to the latest Taylor Swift concert (I was originally going to say Billy Joel but that would date me severely).

There are variations of queues such as double-ended ones where you can enqueue and dequeue at either end but the vast majority would be the simpler form:

           +---+---+---+
enqueue -> | 3 | 2 | 1 | -> dequeue
           +---+---+---+

That diagram shows a queue where you've enqueued the numbers 1, 2 and 3 in that order, without yet dequeuing any.

By way of example, here's some Python code that shows a simplistic queue in action, with enqueue and dequeue functions. Were it more serious code, it would be implemented as a class but it should be enough to illustrate the workings:

import random

def enqueue(lst, itm):
    lst.append(itm)        # Just add item to end of list.
    return lst             # And return list (for consistency with dequeue).

def dequeue(lst):
    itm = lst[0]           # Grab the first item in list.
    lst = lst[1:]          # Change list to remove first item.
    return (itm, lst)      # Then return item and new list.

# Test harness. Start with empty queue.

myList = []

# Enqueue or dequeue a bit, with latter having probability of 10%.

for _ in range(15):
    if random.randint(0, 9) == 0 and len(myList) > 0:
        (itm, myList) = dequeue(myList)
        print(f"Dequeued {itm} to give {myList}")
    else:
        itm = 10 * random.randint(1, 9)
        myList = enqueue(myList, itm)
        print(f"Enqueued {itm} to give {myList}")

# Now dequeue remainder of list.

print("========")
while len(myList) > 0:
    (itm, myList) = dequeue(myList)
    print(f"Dequeued {itm} to give {myList}")

A sample run of that shows it in operation:

Enqueued 70 to give [70]

Enqueued 40 to give [70, 20, 40]

Following expression returns true:

'qwe'.constructor === String

Following expression returns true:

typeof 'qwe' === 'string'

Following expression returns false (sic!):

typeof new String('qwe') === 'string'

Following expression returns true:

typeof new String('qwe').valueOf() === 'string'

Best and right way (imho):

if (someVariable.constructor === String) {
   ...
}

throw $e->getMessage();

You try to throw a string

As a sidenote: Exceptions are usually to define exceptional states of the application and not for error messages after validation. Its not an exception, when a user gives you invalid data

match_parent is not supported, so use android:layout_width="0dp". With 0dp, you can think of your constraints as 'scalable' rather than 'filling whats left'.

Also, 0dp can be defined by a position, where match_parent relies on it's parent for it's position (x,y and width, height)

One classic approach to this problem is to use the "decorate, sort, undecorate" idiom, which is especially simple using python's built-in zip function:

>>> list1 = [3,2,4,1, 1]
>>> list2 = ['three', 'two', 'four', 'one', 'one2']
>>> list1, list2 = zip(*sorted(zip(list1, list2)))
>>> list1
(1, 1, 2, 3, 4)
>>> list2 
('one', 'one2', 'two', 'three', 'four')

These of course are no longer lists, but that's easily remedied, if it matters:

>>> list1, list2 = (list(t) for t in zip(*sorted(zip(list1, list2))))
>>> list1
[1, 1, 2, 3, 4]
>>> list2
['one', 'one2', 'two', 'three', 'four']

It's worth noting that the above may sacrifice speed for terseness; the in-place version, which takes up 3 lines, is a tad faster on my machine for small lists:

>>> %timeit zip(*sorted(zip(list1, list2)))
100000 loops, best of 3: 3.3 us per loop
>>> %timeit tups = zip(list1, list2); tups.sort(); zip(*tups)
100000 loops, best of 3: 2.84 us per loop

On the other hand, for larger lists, the one-line version could be faster:

>>> %timeit zip(*sorted(zip(list1, list2)))
100 loops, best of 3: 8.09 ms per loop
>>> %timeit tups = zip(list1, list2); tups.sort(); zip(*tups)
100 loops, best of 3: 8.51 ms per loop

As Quantum7 points out, JSF's suggestion is a bit faster still, but it will probably only ever be a little bit faster, because Python uses the very same DSU idiom internally for all key-based sorts. It's just happening a little closer to the bare metal. (This shows just how well optimized the zip routines are!)

I think the zip-based approach is more flexible and is a little more readable, so I prefer it.

They have the same speed. Maybe in some special architecture what he/she said is right, but in the x86 family at least I know they are the same. Because for doing this the CPU will do a substraction (a - b) and then check the flags of the flag register. Two bits of that register are called ZF (zero Flag) and SF (sign flag), and it is done in one cycle, because it will do it with one mask operation.

Laravel Framework 5.6.26

return more than one array then we use compact('array1', 'array2', 'array3', ...) to return view.

viewblade is the frontend (view) blade.

return view('viewblade', compact('view1','view2','view3','view4'));

Use -exec:

"your-script-name": "nodemon [options] --exec 'npm start -s'"

In the case of difference between [] and list(), there is a pitfall that I haven't seen anyone else point out. If you use a dictionary as a member of the list, the two will give entirely different results:

In [1]: foo_dict = {"1":"foo", "2":"bar"}

In [2]: [foo_dict]
Out [2]: [{'1': 'foo', '2': 'bar'}]

In [3]: list(foo_dict)
Out [3]: ['1', '2'] 

the only thing you can do is to change your signature to

public static <E> E[] appendToArray(E[] array, E item)

Important details:

Generic expressions preceding the return value always introduce (declare) a new generic type variable.

Additionally, type variables between types (ArrayUtils) and static methods (appendToArray) never interfere with each other.

So, what does this mean: In my answer <E> would hide the E from ArrayUtils<E> if the method wouldn't be static. AND <E> has nothing to do with the E from ArrayUtils<E>.

To reflect this fact better, a more correct answer would be:

public static <I> I[] appendToArray(I[] array, I item)

use ggguG

gg: goes to the first line.

gu: change to lowercase.

G: goes to the last line.

I run MariaDB (MySQL compatible) on two machines locally. I'm not sure what prompted the error and nothing I tried worked. So I stopped the service, deleted everything in MariaDB's directory (except the data directory) and copied the files from my secondary machine and everything is working well enough as far as I can tell.

For a live server it'd be a bit different and a super-guru might be able to add an insight comment (e.g. something outside of the data directory might have something to do with preventing data corruption or indexes in example?). I would just stop the service and copy the entire directory once every month or so and then start the service again.

Kotlin Extension Properties

No file will be create when you make a File object, it is only an interface.

To make working with files easier, there is an existing .toFile function on Uri

You can also add an extension property on File and/or Uri, to simplify usage further.

val File?.exists get() = this?.exists() ?: false
val Uri?.exists get() = File(this.toString).exists()

Then just use uri.exists or file.exists to check.

Example from MVC 4 for dropdownlist validation on Submit using Dataannotation and ViewBag (less line of code)

Models:

namespace Project.Models
{
    public class EmployeeReferral : Person
    {

        public int EmployeeReferralId { get; set; }


        //Company District
        //List                
        [Required(ErrorMessage = "Required.")]
        [Display(Name = "Employee District:")]
        public int? DistrictId { get; set; }

    public virtual District District { get; set; }       
}


namespace Project.Models
{
    public class District
    {
        public int? DistrictId { get; set; }

        [Display(Name = "Employee District:")]
        public string DistrictName { get; set; }
    }
}

EmployeeReferral Controller:

namespace Project.Controllers
{
    public class EmployeeReferralController : Controller
    {
        private ProjDbContext db = new ProjDbContext();

        //
        // GET: /EmployeeReferral/

        public ActionResult Index()
        {
            return View();
        }

 public ActionResult Create()
        {
            ViewBag.Districts = db.Districts;            
            return View();
        }

View:

<td>
                    <div class="editor-label">
                        @Html.LabelFor(model => model.DistrictId, "District")
                    </div>
                </td>
                <td>
                    <div class="editor-field">
                        @*@Html.DropDownList("DistrictId", "----Select ---")*@
                        @Html.DropDownListFor(model => model.DistrictId, new SelectList(ViewBag.Districts, "DistrictId", "DistrictName"), "--- Select ---")
                        @Html.ValidationMessageFor(model => model.DistrictId)                                                
                    </div>
                </td>

Why can't we use ViewBag for populating dropdownlists that can be validated with Annotations. It is less lines of code.

It should not effect the load time much since you are overriding parts of the base stylesheet.

Here are some best practices I personally follow:

1. Always load custom CSS after the base CSS file (not responsive).
2. Avoid using !important if possible. That can override some important styles from the base CSS files.
3. Always load bootstrap-responsive.css after custom.css if you don't want to lose media queries. - MUST FOLLOW
4. Prefer modifying required properties (not all).

Here is how I would do it in C++

size_t size = 500;
char* dynamicAllocatedString = new char[ size ];

Use same principal for any struct or c++ class.

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

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

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

It depends upon what operations you will be doing more on the List.

ArrayList is faster to access an indexed value. It is much worse when inserting or deleting objects.

To find out more, read any article that talks about the difference between arrays and linked lists.

If you face an issue of CORS, you can use https://api.ipify.org/.

function httpGet(theUrl)
{
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", theUrl, false );
    xmlHttp.send( null );
    return xmlHttp.responseText;
}


publicIp = httpGet("https://api.ipify.org/");
alert("Public IP: " + publicIp);

I agree that using synchronous HTTP call is not good idea. You can use async ajax call then.

This should work...

var displayDate = new Date().toLocaleDateString();

alert(displayDate);

But I suspect you are trying it on something else, for example:

var displayDate = Date.now.toLocaleDateString(); // No!

alert(displayDate);

The PHP superglobal $_POST, only is supposed to wrap data that is either

• application/x-www-form-urlencoded (standard content type for simple form-posts) or
• multipart/form-data (mostly used for file uploads)

This is because these are the only content types that must be supported by user agents. So the server and PHP traditionally don't expect to receive any other content type (which doesn't mean they couldn't).

So, if you simply POST a good old HTML form, the request looks something like this:

POST /page.php HTTP/1.1

key1=value1&key2=value2&key3=value3

But if you are working with Ajax a lot, this probaby also includes exchanging more complex data with types (string, int, bool) and structures (arrays, objects), so in most cases JSON is the best choice. But a request with a JSON-payload would look something like this:

POST /page.php HTTP/1.1

{"key1":"value1","key2":"value2","key3":"value3"}

The content would now be application/json (or at least none of the above mentioned), so PHP's $_POST-wrapper doesn't know how to handle that (yet).

The data is still there, you just can't access it through the wrapper. So you need to fetch it yourself in raw format with file_get_contents('php://input') (as long as it's not multipart/form-data-encoded).

This is also how you would access XML-data or any other non-standard content type.

You should use CSS to align the textbox. The reason your code above does not work is because by default a div's width is the same as the container it's in, therefore in your example it is pushed below.

The following would work.

<td  colspan="2" class="cell">
                <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>        
                <asp:TextBox ID="TextBox3" runat="server" CssClass="righttextbox"></asp:TextBox>       
</td>

In your CSS file:

.cell
{
text-align:left;
}

.righttextbox
{
float:right;
}

First check the Visual studio version of the developer PC which can publish the solution(project). as shown is for VS 2013

 /p:VisualStudioVersion=12.0

add the above command line to specify what kind of a visual studio version should build the project. As previous answers, this might happen when we are trying to publish only one project, not the whole solution.

So the complete code would be something like this

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe" "C:\Program Files (x86)\Jenkins\workspace\Jenkinssecondsample\MVCSampleJenkins\MVCSampleJenkins.csproj" /T:Build;Package /p:Configuration=DEBUG /p:OutputPath="obj\DEBUG" /p:DeployIisAppPath="Default Web Site/jenkinsdemoapp" /p:VisualStudioVersion=12.0

What I would first is make the following CSS code:

#bloc1 {
   float: left
}

This will make #bloc2 be inline with #bloc1.

To make it central, I would add #bloc1 and #bloc2 in a separate div. For example:

<style type="text/css">
    #wrapper { margin: 0 auto; }
</style>
<div id="wrapper">
    <div id="bloc1"> ... </div>
    <div id="bloc2"> ... </div>
</div>

Just in case somebody didn't understand the 6th time around:

setResizable(false);

For me, the refresh in xcode 5 prefs->accounts was doing nothing. At one point it showed me three profiles so I thought I was one refresh away, but after the next refresh it went back to just one profile, so I abandoned this method.

If anyone gets this far and is still struggling, here's what I did:

1. Close xcode 5
2. Open xcode 4.6.2
3. Go to Window->Organizer->Provisioning Profiles
4. Press Refresh arrow on bottom right

When I did this, everything synced up perfectly. It even told me what it was downloading each step of the way like good software does. After the sync completed, I closed xcode 4.6.2, re-opened xcode 5 and went to preferences->accounts and voila, all of my profiles are now available in xocde 5.

I have the complete shortcuts list:

1. Ctrl+a Move cursor to start of line
2. Ctrl+e Move cursor to end of line
3. Ctrl+b Move back one character
4. Alt+b Move back one word
5. Ctrl+f Move forward one character
6. Alt+f Move forward one word
7. Ctrl+d Delete current character
8. Ctrl+w Cut the last word
9. Ctrl+k Cut everything after the cursor
10. Alt+d Cut word after the cursor
11. Alt+w Cut word before the cursor
12. Ctrl+y Paste the last deleted command
13. Ctrl+_ Undo
14. Ctrl+u Cut everything before the cursor
15. Ctrl+xx Toggle between first and current position
16. Ctrl+l Clear the terminal
17. Ctrl+c Cancel the command
18. Ctrl+r Search command in history - type the search term
19. Ctrl+j End the search at current history entry
20. Ctrl+g Cancel the search and restore original line
21. Ctrl+n Next command from the History
22. Ctrl+p previous command from the History

In layout file.

<TextView
   android:id="@+id/myTextView"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:text="Some Text"
   android:textSize="18sp"
   android:textColor="#000000"/>

In Activity

TextView myTextView = (TextView)findViewById(R.id.myTextView);
myTextView.setText("Hello World!");

One way is to use window.print() function. Which does not require any library

Pros

1.No external library require.

2.We can print only selected parts of body also.

3.No css conflicts and js issues.

4.Core html/js functionality

---Simply add below code

CSS to

@media print {
        body * {
            visibility: hidden; // part to hide at the time of print
            -webkit-print-color-adjust: exact !important; // not necessary use         
               if colors not visible
        }

        #printBtn {
            visibility: hidden !important; // To hide 
        }

        #page-wrapper * {
            visibility: visible; // Print only required part
            text-align: left;
            -webkit-print-color-adjust: exact !important;
        }
    }

JS code - Call bewlow function on btn click

$scope.printWindow = function () {
  window.print()
}

Note: Use !important in every css object

Example -

.legend  {
  background: #9DD2E2 !important;
}

For JavaScript arrays, you use Both push() and concat() function.

var array = [1, 2, 3];
array.push(4, 5);         //use push for appending a single array.




var array1 = [1, 2, 3];
var array2 = [4, 5, 6];

var array3 = array1.concat(array2);   //It is better use concat for appending more then one array.

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.

You should be doing something more like this:

class MyClassTest
{
    [TestMethod]
    public void MyMethodTest()
    {
        string action = "test";
        Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();

        mockSomeClass.Setup(mock => mock.DoSomething());

        MyClass myClass = new MyClass(mockSomeClass.Object);
        myClass.MyMethod(action);

        // Explicitly verify each expectation...
        mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());

        // ...or verify everything.
        // mockSomeClass.VerifyAll();
    }
}

In other words, you are verifying that calling MyClass#MyMethod, your class will definitely call SomeClass#DoSomething once in that process. Note that you don't need the Times argument; I was just demonstrating its value.

A straightforward approach:

def round_time(dt, round_to_seconds=60):
    """Round a datetime object to any number of seconds
    dt: datetime.datetime object
    round_to_seconds: closest number of seconds for rounding, Default 1 minute.
    """
    rounded_epoch = round(dt.timestamp() / round_to_seconds) * round_to_seconds
    rounded_dt = datetime.datetime.fromtimestamp(rounded_epoch).astimezone(dt.tzinfo)
    return rounded_dt

use strchr function when dealing with C strings.

const char * strchr ( const char * str, int character );

Here is an example of what you want to do.

/* strchr example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char invalids[] = ".@<>#";
  char * pch;
  pch=strchr(invalids,'s');//is s an invalid character?
  if (pch!=NULL)
  {
    printf ("Invalid character");
  }
  else 
  {
     printf("Valid character");
  } 
  return 0;
}

Use memchr when dealing with memory blocks (as not null terminated arrays)

const void * memchr ( const void * ptr, int value, size_t num );

/* memchr example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char * pch;
  char invalids[] = "@<>#";
  pch = (char*) memchr (invalids, 'p', strlen(invalids));
  if (pch!=NULL)
    printf (p is an invalid character);
  else
    printf ("p valid character.\n");
  return 0;
}

Add jstl jar to your application classpath.

Old question, but half a decade later, it’s worth revisiting. Here I am only discussing the selector aspect of jQuery.

document.querySelector[All] is supported by all current browsers, down to IE8, so compatibility is no longer an issue. I have also found no performance issues to speak of (it was supposed to be slower than document.getElementById, but my own testing suggests that it’s slightly faster).

Therefore when it comes to manipulating an element directly, it is to be preferred over jQuery.

For example:

var element=document.querySelector('h1');
element.innerHTML='Hello';

is vastly superior to:

var $element=$('h1');
$element.html('hello');

In order to do anything at all, jQuery has to run through a hundred lines of code (I once traced through code such as the above to see what jQuery was actually doing with it). This is clearly a waste of everyone’s time.

The other significant cost of jQuery is the fact that it wraps everything inside a new jQuery object. This overhead is particularly wasteful if you need to unwrap the object again or to use one of the object methods to deal with properties which are already exposed on the original element.

Where jQuery has an advantage, however, is in how it handles collections. If the requirement is to set properties of multiple elements, jQuery has a built-in each method which allows something like this:

var $elements=$('h2');  //  multiple elements
$elements.html('hello');

To do so with Vanilla JavaScript would require something like this:

var elements=document.querySelectorAll('h2');
elements.forEach(function(e) {
    e.innerHTML='Hello';
});

which some find daunting.

jQuery selectors are also slightly different, but modern browsers (excluding IE8) won’t get much benefit.

As a rule, I caution against using jQuery for new projects:

• jQuery is an external library adding to the overhead of the project, and to your dependency on third parties.
• jQuery function is very expensive, processing-wise.
• jQuery imposes a methodology which needs to be learned and may compete with other aspects of your code.
• jQuery is slow to expose new features in JavaScript.

If none of the above matters, then do what you will. However, jQuery is no longer as important to cross-platform development as it used to be, as modern JavaScript and CSS go a lot further than they used to.

This makes no mention of other features of jQuery. However, I think that they, too, need a closer look.

Just add them to the parameter string.

window.open(this.href,'targetWindow','toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=350,height=250')

Use ByteArrayInputStream:

InputStream is = new ByteArrayInputStream(decodedBytes);

private class ObjectAdapter extends BaseAdapter {

    private Context context;
    private List<Object>objects;

    public ObjectAdapter(Context context, List<Object> objects) {
        this.context = context;
        this.objects = objects;
    }

    @Override
    public int getCount() {
        return objects.size();
    }

    @Override
    public Object getItem(int position) {
        return objects.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;

        if(convertView==null){
            holder = new ViewHolder();
            convertView = LayoutInflater.from(context).inflate(android.R.layout.simple_list_item_1, parent, false);
            holder.text = (TextView) convertView.findViewById(android.R.id.text1);
            convertView.setTag(holder);
        }else{
            holder = (ViewHolder) convertView.getTag();
        }

        holder.text.setText(getItem(position).toString()));
        return convertView;
    }

    class ViewHolder {
        TextView text;
    }
}

Starting from Java 8, there is a completely new officially supported way to do this:

    String s = "2020-02-13T18:51:09.840Z";
    TemporalAccessor ta = DateTimeFormatter.ISO_INSTANT.parse(s);
    Instant i = Instant.from(ta);
    Date d = Date.from(i);

What do you want? Speed or simplicity? For speed, go for a loop based approach. For simplicity, go for a one liner RegEx based approach.

Speed

public boolean isAlpha(String name) {
    char[] chars = name.toCharArray();

    for (char c : chars) {
        if(!Character.isLetter(c)) {
            return false;
        }
    }

    return true;
}

Simplicity

public boolean isAlpha(String name) {
    return name.matches("[a-zA-Z]+");
}

runfile('abc.py', ['arg1', 'arg2'])

I believe you can pass in event into the function inline which will be the event object for the raised event in W3C compliant browsers (i.e. older versions of IE will still require detection inside of your event handler function to look at window.event).

A quick example.

function sayHi(e) {_x000D_
   e.preventDefault();_x000D_
   alert("hi");_x000D_
}

<a href="http://google.co.uk" onclick="sayHi(event);">Click to say Hi</a>

1. Run it as is and notice that the link does no redirect to Google after the alert.
2. Then, change the event passed into the onclick handler to something else like e, click run, then notice that the redirection does take place after the alert (the result pane goes white, demonstrating a redirect).

Use :

 $(this).parent().css("background-image", "url(/images/r-srchbg_white.png) no-repeat;");

instead of

 $(this).parent().css("background", "url(/images/r-srchbg_white.png) no-repeat;");

More examples you cand see here

Only first part of Justin's answer is correct. Using "%.3g" will not work for all cases as .3 is not the precision, but total number of digits. Try it for numbers like 1000.123 and it breaks.

So, I would use what Justin is suggesting:

>>> ('%.4f' % 12340.123456).rstrip('0').rstrip('.')
'12340.1235'
>>> ('%.4f' % -400).rstrip('0').rstrip('.')
'-400'
>>> ('%.4f' % 0).rstrip('0').rstrip('.')
'0'
>>> ('%.4f' % .1).rstrip('0').rstrip('.')
'0.1'

I really like the philosophy of the ezSQL database library, which wraps the native SQL methods in an easier-to-use interface.

Fetching a single value from the database is trivial:

  $id = $db->get_var("SELECT id FROM games WHERE ...");

It also makes it easy to fetch a single row, column, or set of rows.

First of all, I want to say a big screw you to React for designing an interface that doesn't let us access 'ref' on the instantiated child components, in whatever context, without having to use the 'forwardRef' "hack" (which technically only works on specific/single instances, and not dynamic collections). Thanks for making our lives harder with your proprietary hook crap and now forcing us to use functional components (which can't inherit base functionality without more hacks). Why did JavaScript add class support to begin with? Right...

With that said, here is how I solve the problem for dynamic components:

On the parent, dynamically create references to the child components, for example:

class Form extends Component {
    fieldRefs: [];

    componentWillMount = () => {
        this.fieldRefs = [];
        for(let f of this.props.children) {
            if (f && f.type.name == 'FormField') {
                f.ref = createRef();
                this.fieldRefs.push(f);
            }
        }
    }

    public getFields = () => {
        let data = {};

        for(let r of this.fieldRefs) {
            let f = r.ref.current;
            data[f.props.id] = f.field.current.value;
        }

        return data;
    }
}

The Child component (ie <FormField />) implements it's own 'field' ref, to be referred to from the parent:

class FormField extends Component {
    field = createRef();
    
    render() {
        return(
            <input ref={this.field} type={type} />
        );
    }
}

Then in your main page, "Parent Parent" component, you can get the field values from the reference with:

class Page extends Component {
    form = createRef();

    onSubmit = () => {
        let fields = this.form.current.getFields();
    }

    render() {
        return (
            <Form ref={this.form}>
                <FormField id="email" type="email" autoComplete="email" label="E-mail" />
                <FormField id="password" type="password" autoComplete="password" label="Password" />

                <div class="button" onClick={this.onSubmit}>Submit</div>
            </Form>
        );
    }
}

I implemented this because I wanted to encapsulate all generic form functionality from a main <Form /> component, and the only way to be able to have the main client/page component set and style its own inner components was to use child components (ie. <FormField /> items within the parent <Form />, which is inside some other <Page /> component).

So, while some might consider this a hack, it's just as hackey as React's attempts to block the actual 'ref' from any parent, which I think is a ridiculous design, however they want to rationalize it.

Also wtf SO. It's 2021 and we still don't have get proper code-editing tools in your editor. Ffs.

For Excel 2011 on Mac it's different. I did it as a three step process.

1. Create a column of values in column A.
2. In column B, to the right of the first cell, create a rule that uses the concatenate function on the column value and ",". For example, assuming A1 is the first row, the formula for B1 is =B1. For the next row to row N, the formula is =Concatenate(",",A2). You end up with:

QA
,Sekuli
,Testing
,Applitools
,Visual Testing
,Test Automation
,Selenium

3. In column C create a formula that concatenates all previous values. Because it is additive you will get all at the end. The formula for cell C1 is =B1. For all other rows to N, the formula is =Concatenate(C1,B2). And you get:

QA,Sekuli
QA,Sekuli,Testing
QA,Sekuli,Testing,Applitools
QA,Sekuli,Testing,Applitools,Visual Testing
QA,Sekuli,Testing,Applitools,Visual Testing,Test Automation
QA,Sekuli,Testing,Applitools,Visual Testing,Test Automation,Selenium

The last cell of the list will be what you want. This is compatible with Excel on Windows or Mac.

string1.equals(string2) is the way.

It returns true if string1 is equals to string2 in value. Else, it will return false.

equals reference

I have found... margin: 0 auto; works for me. But I have also seen it NOT work due to the class being trumped by another specificity that had ... float:left; so watch for that you may need to add ... float:none; this worked in my case as I was coding a media query.

Here, try this (assuming it's a small file!):

<?php
echo file_get_contents( "filename.php" ); // get the contents, and echo it out.
?>

Documentation is here.

In my case, Build Action of the resource file was already Embedded Resource but every time I ran update-database, I got the same error, so i did the fellow steps and it's worked:

1. Change Build Action property to Compile
2. Build (got so many errors)
3. Change back Build Action property to Embedded Resource
4. update-database

And for some reason it's worked.

I'll be the first to admit Java can be very verbose, but I don't think this is unreasonable:

JOptionPane.showMessageDialog(null, "My Goodness, this is so concise");

If you statically import javax.swing.JOptionPane.showMessageDialog using:

import static javax.swing.JOptionPane.showMessageDialog;

This further reduces to

showMessageDialog(null, "This is even shorter");

Often a simple and effective way to achieve this is to keep track of when and where you are modifying the DOM.

You can do this by creating one central function that is always responsible for modifying the DOM. You then do whatever cleanup you need on the modified element from within this function.

In a recent application, I didn't need immediate action so I used a callback for the handly load() function, to add a class to any modified elements and then updated all modified elements every few seconds with a setInterval timer.

$($location).load("my URL", "", $location.addClass("dommodified"));

Then you can handle it however you want - e.g.

setInterval("handlemodifiedstuff();", 3000); 
function handlemodifiedstuff()
{
    $(".dommodified").each(function(){/* Do stuff with $(this) */});
}

for ( int i=0 ; i<=list.size() ; i++){
....}

By executing this for loop , the loop will execute with a thrown exception as IndexOutOfBoundException cause, suppose list size is 10 , so when index i will get to 10 i.e when i=10 the exception will be thrown cause index=size, i.e. i=size and as known that Java considers index starting from 0,1,2...etc the expression which Java agrees upon is index < size. So the solution for such exception is to make the statement in loop as i<list.size()

for ( int i=0 ; i<list.size() ; i++){
...}

Since you say you want to access by position once your data is read in, you should know about R's subsetting/ indexing functions.

The easiest is

df[row,column]
#example
df[1:5,] #rows 1:5, all columns
df[,5] #all rows, column 5. 

Other methods are here. I personally use the dplyr package for intuitive data manipulation (not by position).

if you are using sometimes playerID.stopVideo(); doesnot work, here is a trick,

 function stopVideo() {
           playerID.seekTo(0);
    playerID.stopVideo();
}

A good example would be a cache.

For recently accessed objects, you want to keep them in memory, so you hold a strong pointer to them. Periodically, you scan the cache and decide which objects have not been accessed recently. You don't need to keep those in memory, so you get rid of the strong pointer.

But what if that object is in use and some other code holds a strong pointer to it? If the cache gets rid of its only pointer to the object, it can never find it again. So the cache keeps a weak pointer to objects that it needs to find if they happen to stay in memory.

This is exactly what a weak pointer does -- it allows you to locate an object if it's still around, but doesn't keep it around if nothing else needs it.

Try something like this

select Cast((SPGI09_EARLY_OVER_T – (SPGI09_OVER_WK_EARLY_ADJUST_T) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T  + SPGR99_ON_TIME_Q)) as varchar(20) + '%' as percentageAmount
from CSPGI09_OVERSHIPMENT

I presume the value is a representation in percentage - if not convert it to a valid percentage total, then add the % sign and convert the column to varchar.

first, you need to find the toolbox that you need. There are many people developing 3rd party toolboxes for Matlab, so there isn't just one single place where you can find "the image processing toolbox". That said, a good place to start looking is the Matlab Central which is a Mathworks-run site for exchanging all kinds of Matlab-related material.

Once you find a toolbox you want, it will be in some compressed format, and its developers might have a "readme" file that details on how to install it. If it isn't the case, a generic way to attempt installation is to place the toolbox in any directory on your drive, and then add it to Matlab path, e.g., going to File -> Set Path... -> Add Folder or Add with Subfolders (I'm writing for memory but this is definitely close).

Otherwise, you can extract all .m files in your working directory, if you don't want to use downloaded toolbox in more than one project.

This happens when saving an object when Hibernate thinks it needs to save an object that is associated with the one you are saving.

I had this problem and did not want to save changes to the referenced object so I wanted the cascade type to be NONE.

The trick is to ensure that the ID and VERSION in the referenced object is set so that Hibernate does not think that the referenced object is a new object that needs saving. This worked for me.

Look through all of the relationships in the class you are saving to work out the associated objects (and the associated objects of the associated objects) and ensure that the ID and VERSION is set in all objects of the object tree.

The difference comes in when you use the struct.

The first way you have to do:

struct myStruct aName;

The second way allows you to remove the keyword struct.

myStruct aName;

A simple way to find this out in Windows is to run SQLPlus from your Oracle homes's bin directory and then check Task Manager. If it is a 32-bit version of SQLPlus, you'll see a process on the Processes tab that looks like this:

sqlplus.exe *32

If it is 64-bit, the process will look like this:

sqlplus.exe

When filtering a DataFrame with string values, I find that the pyspark.sql.functions lower and upper come in handy, if your data could have column entries like "foo" and "Foo":

import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))

on tomcat v.7 (vanilla installation)

in your conf/server.xml add the following bit towards the end of the file, just before the </Host> closing tag:

<Context path="" docBase="app_name">
    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>

Note that docBase attribute. It's the important bit. You either make sure you've deployed app_name before you change your root web app, or just copy your unpacked webapp (app_name) into your tomcat's webapps folder. Startup, visit root, see your app_name there!

If you are using xampp you can find php.ini file by going into xampp control panel and and clicking config button in front of Apache.

You're probably not accessing it correctly. You can output it directly or cast it as a string. (in this example, the casting is superfluous, as echo automatically does it anyway)

$content = simplexml_load_string(
    '<content><![CDATA[Hello, world!]]></content>'
);
echo (string) $content;

// or with parent element:

$foo = simplexml_load_string(
    '<foo><content><![CDATA[Hello, world!]]></content></foo>'
);
echo (string) $foo->content;

You might have better luck with LIBXML_NOCDATA:

$content = simplexml_load_string(
    '<content><![CDATA[Hello, world!]]></content>'
    , null
    , LIBXML_NOCDATA
);

For Ubuntu: add extension=php_curl.so to php.ini to enable, if necessary. Then sudo service apache2 restart

this is generally taken care of automatically, but there are situations - eg, in shared development environments - where it can become necessary to re-enable manually.

The thumbprint will match all three of these conditions:

1. Fatal Error on curl_init() call
2. in php_info, you will see the curl module author (indicating curl is installed and available)
3. also in php_info, you will see no curl config block (indicating curl wasn't loaded)

For mac users: in new version there is no setting.xml, alternate way is to

navigate to SmartGit preferences folder using terminal

cd /Library/Preferences/SmartGit/

use ls command to see list of folders .. simply delete SmartGit version folder you find using command rm -r <main-smartgit-version> and reopen the SmartGit app. :)

There is a free python tool called YouTube transcript API

You can use it in scripts or as a command line tool:

pip install youtube_transcript_api

My case is the page is sending multiple requests with different parameters when it was open. So most are being "stalled". Following requests immediately sent gets "stalled". Avoiding unnecessary requests would be better (to be lazy...).

Well any Javascript object functions sort-of like a "map"

randomObject['hello'] = 'world';

Typically people build simple objects for the purpose:

var myMap = {};

// ...

myMap[newKey] = newValue;

edit — well the problem with having an explicit "put" function is that you'd then have to go to pains to avoid having the function itself look like part of the map. It's not really a Javascripty thing to do.

13 Feb 2014 — modern JavaScript has facilities for creating object properties that aren't enumerable, and it's pretty easy to do. However, it's still the case that a "put" property, enumerable or not, would claim the property name "put" and make it unavailable. That is, there's still only one namespace per object.

One of the following may cause the exception:

1. Add an empty public constructor to your Fields class, JAXB uses reflection to load your classes, that's why the exception is thrown.
2. Add separate getter and setter for your list.

Hope you have key field is two tables.

 UPDATE tblindiantime t
   SET CountryName = (SELECT c.BusinessCountry 
                     FROM contacts c WHERE c.Key = t.Key 
                     )

C++ uses structs primarily for 1) backwards compatibility with C and 2) POD types. C structs do not have methods, inheritance or visibility.

I had the same issue. When I use window.location, $window.location or even <a href="..." target="_self"> the route does not refresh the page. So the cached services are used which is not what I want in my app. I resolved it by adding window.location.reload() after window.location to force the page to reload after routing. This method seems to load the page twice though. Might be a dirty trick, but it does the work. This is how I have it now:

  $scope.openPage = function (pageName) {
      window.location = '#/html/pages/' + pageName;
      window.location.reload();
  };

Your code can get messy fast when dealing with CSS3 transitions. I would recommend using a plugin such as jQuery Transit that handles the complexity of CSS3 animations/transitions.

Moreover, the plugin uses webkit-transform rather than webkit-transition, which allows for mobile devices to use hardware acceleration in order to give your web apps that native look and feel when the animations occur.

JS Fiddle Live Demo

Javascript:

$("#startTransition").on("click", function()
{

    if( $(".boxOne").is(":visible")) 
    {
        $(".boxOne").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxOne").hide(); });
        $(".boxTwo").css({ x: '100%' });
        $(".boxTwo").show().transition({ x: '0%', opacity: 1.0 });
        return;        
    }

    $(".boxTwo").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxTwo").hide(); });
    $(".boxOne").css({ x: '100%' });
    $(".boxOne").show().transition({ x: '0%', opacity: 1.0 });

});

Most of the hard work of getting cross-browser compatibility is done for you as well and it works like a charm on mobile devices.

Use pyplot.text() (import matplotlib.pyplot as plt)

import matplotlib.pyplot as plt

x=[1,2,3]
y=[9,8,7]

plt.plot(x,y)
for a,b in zip(x, y): 
    plt.text(a, b, str(b))
plt.show()

To correctly save the instance state of Fragment you should do the following:

1. In the fragment, save instance state by overriding onSaveInstanceState() and restore in onActivityCreated():

class MyFragment extends Fragment {

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ...
        if (savedInstanceState != null) {
            //Restore the fragment's state here
        }
    }
    ...
    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        //Save the fragment's state here
    }

}

2. And important point, in the activity, you have to save the fragment's instance in onSaveInstanceState() and restore in onCreate().

class MyActivity extends Activity {

    private MyFragment 

    public void onCreate(Bundle savedInstanceState) {
        ...
        if (savedInstanceState != null) {
            //Restore the fragment's instance
            mMyFragment = getSupportFragmentManager().getFragment(savedInstanceState, "myFragmentName");
            ...
        }
        ...
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        //Save the fragment's instance
        getSupportFragmentManager().putFragment(outState, "myFragmentName", mMyFragment);
    }

}

Hope this helps.

Just pass the array to the Set constructor. The Set constructor accepts an iterable parameter. The Array object implements the iterable protocol, so its a valid parameter.

var arr = [55, 44, 65];_x000D_
var set = new Set(arr);_x000D_
console.log(set.size === arr.length);_x000D_
console.log(set.has(65));

    **The task can be acheived by creating two stacks:**



import java.util.Stack;
    /*
     * 
     * Find min in stack using O(n) Space Complexity
     */
    public class DeleteMinFromStack {

        void createStack(Stack<Integer> primary, Stack<Integer> minStack, int[] arr) {
    /* Create main Stack and in parallel create the stack which contains the minimum seen so far while creating main Stack */
            primary.push(arr[0]);
            minStack.push(arr[0]);

            for (int i = 1; i < arr.length; i++) {
                primary.push(arr[i]);
                if (arr[i] <= minStack.peek())// Condition to check to push the value in minimum stack only when this urrent value is less than value seen at top of this stack */
                    minStack.push(arr[i]);

You have some options to handle this deprecation the right (and future proof) way, depending on which kind of drawable you are loading:

A) drawables with theme attributes

ContextCompat.getDrawable(getActivity(), R.drawable.name);

You'll obtain a styled Drawable as your Activity theme instructs. This is probably what you need.

B) drawables without theme attributes

ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

You'll get your unstyled drawable the old way. Please note: ResourcesCompat.getDrawable() is not deprecated!

EXTRA) drawables with theme attributes from another theme

ResourcesCompat.getDrawable(getResources(), R.drawable.name, anotherTheme);

I faced the same issue before. I cleared all the IE caches/browsing history/cookies & re-launch IE. It works after caches removed.

You may have a try. :)

Your web.config file should have this structure:

<configuration>
    <connectionStrings>
        <add name="MyConnectionString" connectionString="..." />
    </connectionStrings>
</configuration>

Then, to create a SQL connection using the connection string named MyConnectionString:

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);

If you'd prefer to keep your connection strings in the AppSettings section of your configuration file, it would look like this:

<configuration>
    <appSettings>
        <add key="MyConnectionString" value="..." />
    </appSettings>
</configuration>

And then your SqlConnection constructor would look like this:

SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["MyConnectionString"]);

Laravel 5.2 <= 5.5

    use Carbon\Carbon; // You need to import Carbon
    $current_time = Carbon::now()->toDayDateTimeString(); // Wed, May 17, 2017 10:42 PM
    $current_timestamp = Carbon::now()->timestamp; // Unix timestamp 1495062127

In addition, this is how to change datetime format for given date & time, in blade:

{{\Carbon\Carbon::parse($dateTime)->format('D, d M \'y, H:i')}}

Laravel 5.6 <

$current_timestamp = now()->timestamp;

if the day itself doesn't matter do this:

echo date('Y-m-d', strtotime(date('Y-m')." -1 month"));

For completeness, PHP:

php -r 'echo time();'

In BASH:

clitime=$(php -r 'echo time();')
echo $clitime

Setting them later

If you don't know the number of the plots you are going to plot you can change the colours once you have plotted them retrieving the number directly from the plot using .lines, I use this solution:

Some random data

import matplotlib.pyplot as plt
import numpy as np

fig1 = plt.figure()
ax1 = fig1.add_subplot(111)


for i in range(1,15):
    ax1.plot(np.array([1,5])*i,label=i)

The piece of code that you need:

colormap = plt.cm.gist_ncar #nipy_spectral, Set1,Paired   
colors = [colormap(i) for i in np.linspace(0, 1,len(ax1.lines))]
for i,j in enumerate(ax1.lines):
    j.set_color(colors[i])
  

ax1.legend(loc=2)

The result is the following:

Hi please check the below link

https://www.postgresql.org/docs/current/xfunc-sql.html

EX:

CREATE FUNCTION sum_n_product_with_tab (x int)
RETURNS TABLE(sum int, product int) AS $$
    SELECT $1 + tab.y, $1 * tab.y FROM tab;
$$ LANGUAGE SQL;

You can also do this by passing function with onclick event

<a onclick="getColor(this);" color="red">

<script type="text/javascript">

function getColor(el)
{
     color = $(el).attr('color');
     alert(color);
}

</script> 

Right-click the Git Bash application link go to Properties and modify the Start in location to be the location you want it to start from.

There is another way to do that without cast:

when(a.method(Matchers.<Class<A>>any())).thenReturn(b);

This solution forces the method any() to return Class<A> type and not its default value (Object).

Every time you get this kind of error

bash: <command>: command not found

• On a host with that command already working with this solution:

  dpkg -S $(which <command>)
  

• Don't have a host with that package installed? Try this:

  apt-file search /bin/<command>
  

If you need this in derived classes, you can put that code in the base class:

protected string GetThisClassName() { return this.GetType().Name; }

Then, you can reach the name in the derived class. Returns derived class name. Of course, when using the new keyword "nameof", there will be no need like this variety acts.

Besides you can define this:

public static class Extension
{
    public static string NameOf(this object o)
    {
        return o.GetType().Name;
    }
}

And then use like this:

public class MyProgram
{
    string thisClassName;

    public MyProgram()
    {
        this.thisClassName = this.NameOf();
    }
}

Just get the class attribute:

var div1Class = $('#div1').attr('class');

Example

<div id="div1" class="accordion accordion_active">

To check the above div for classes contained in it

var a = ("#div1").attr('class'); 
console.log(a);

console output

accordion accordion_active

Without using regex, you can just do:

def get_num(x):
    return int(''.join(ele for ele in x if ele.isdigit()))

Result:

>>> get_num(x)
120
>>> get_num(y)
90
>>> get_num(banana)
200
>>> get_num(orange)
300

EDIT :

Answering the follow up question.

If we know that the only period in a given string is the decimal point, extracting a float is quite easy:

def get_num(x):
    return float(''.join(ele for ele in x if ele.isdigit() or ele == '.'))

Result:

>>> get_num('dfgd 45.678fjfjf')
45.678

Another possibility is to use the options with data attributes, like this(minimum date 1 week before):

<input class='datepicker' data-date-start-date="-1w">

More info: http://bootstrap-datepicker.readthedocs.io/en/latest/options.html

The only way to do that is running the exe and collect the MSI. The thing you must take care of is that if you are tranforming the MSI using MST they might get lost.

I use this batch commandline:

SET TMP=c:\msipath

MD "%TMP%"

SET TEMP=%TMP%

start /d "c:\install" install.exe /L1033

PING 1.1.1.1 -n 1 -w 10000 >NUL

for /R "%TMP%" %%f in (*.msi) do copy "%%f" "%TMP%"

taskkill /F /IM msiexec.exe /T

If you're working with a multiline string, like a code file:

<html>
    <title>test</title>
    <body>
        <h1>test</h1>
    </body>
</html>

And want to replace all leading lines, to get this result:

<html>
<title>test</title>
<body>
<h1>test</h1>
</body>
</html>

You must add the multiline flag to your regex, ^ and $ match line by line:

string.replace(/^\s+|\s+$/gm, '');

Relevant quote from docs:

The "m" flag indicates that a multiline input string should be treated as multiple lines. For example, if "m" is used, "^" and "$" change from matching at only the start or end of the entire string to the start or end of any line within the string.

What I did to fix the problem on Ubuntu was

$ sudo apt-get install libmagickwand-dev
$ sudo apt-get install ImageMagick

Object Model is concerned with the following three concepts Data Abstraction Encapsulation Inheritance The relational model used the basic concept of a relation or table. Object-relational mapping (OR mapping) products integrate object programming language capabilities with relational databases.

Yes, the problem is that there are no commits in "bare". This is a problem with the first commit only, if you create the repos in the order (bare,alice). Try doing:

git push --set-upstream origin master

This would only be required the first time. Afterwards it should work normally.

As Chris Johnsen pointed out, you would not have this problem if your push.default was customized. I like upstream/tracking.

You can configure property inclusion, and numerous other settings, via application.properties:

spring.jackson.default-property-inclusion=non_null

There's a table in the documentation that lists all of the properties that can be used.

If you want more control, you can also customize Spring Boot's configuration programatically using a Jackson2ObjectMapperBuilderCustomizer bean, as described in the documentation:

The context’s Jackson2ObjectMapperBuilder can be customized by one or more Jackson2ObjectMapperBuilderCustomizer beans. Such customizer beans can be ordered (Boot’s own customizer has an order of 0), letting additional customization be applied both before and after Boot’s customization.

Lastly, if you don't want any of Boot's configuration and want to take complete control over how the ObjectMapper is configured, declare your own Jackson2ObjectMapperBuilder bean:

@Bean
Jackson2ObjectMapperBuilder objectMapperBuilder() {
    Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
    // Configure the builder to suit your needs
    return builder;
}

Maybe a bit late, but hope it hellps:

First of all you need to make the field Nullable, then after that so simple - instead of putting a value put this code CURRENT_TIMESTAMP.

This post is now nearly 5 years old! Python-2.7 will stop receiving official updates from python.org in 2020. Also, Python-3.7 has been released. Check out Python-Future on how to make your Python-2 code compatible with Python-3. For updating conda, the documentation now recommends using conda update --all in each of your conda environments to update all packages and the Python executable for that version. Also, since they changed their name to Anaconda, I don't know if the Windows registry keys are still the same.

There have been no updates to Python(x,y) since June of 2015, so I think it's safe to assume it has been abandoned.

As @cxw comments below, these answers are for the same bit-versions, and by bit-version I mean 64-bit vs. 32-bit. For example, these answers would apply to updating from 64-bit Python-2.7.10 to 64-bit Python-2.7.11, ie: the same bit-version. While it is possible to install two different bit versions of Python together, it would require some hacking, so I'll save that exercise for the reader. If you don't want to hack, I suggest that if switching bit-versions, remove the other bit-version first.

• Anaconda and MiniConda can be used with an existing Python installation by disabling the options to alter the Windows PATH and Registry. After extraction, create a symlink to conda in your bin or install conda from PyPI. Then create another symlink called conda-activate to activate in the Anaconda/Miniconda root bin folder. Now Anaconda/Miniconda is just like Ruby RVM. Just use conda-activate root to enable Anaconda/Miniconda.
• Portable Python is no longer being developed or maintained.

TL;DR

• Using Anaconda or miniconda, then just execute conda update --all to keep each conda environment updated,
• same major version of official Python (e.g. 2.7.5), just install over old (e.g. 2.7.4),
• different major version of official Python (e.g. 3.3), install side-by-side with old, set paths/associations to point to dominant (e.g. 2.7), shortcut to other (e.g. in BASH $ ln /c/Python33/python.exe python3).

The answer depends:

1. If OP has 2.7.x and wants to install newer version of 2.7.x, then

   • if using MSI installer from the official Python website, just install over old version, installer will issue warning that it will remove and replace the older version; looking in "installed programs" in "control panel" before and after confirms that the old version has been replaced by the new version; newer versions of 2.7.x are backwards compatible so this is completely safe and therefore IMHO multiple versions of 2.7.x should never necessary.
   • if building from source, then you should probably build in a fresh, clean directory, and then point your path to the new build once it passes all tests and you are confident that it has been built successfully, but you may wish to keep the old build around because building from source may occasionally have issues. See my guide for building Python x64 on Windows 7 with SDK 7.0.
   • if installing from a distribution such as Python(x,y), see their website. Python(x,y) has been abandoned. I believe that updates can be handled from within Python(x,y) with their package manager, but updates are also included on their website. I could not find a specific reference so perhaps someone else can speak to this. Similar to ActiveState and probably Enthought, Python (x,y) clearly states it is incompatible with other installations of Python:

     It is recommended to uninstall any other Python distribution before installing Python(x,y)

   • Enthought Canopy uses an MSI and will install either into Program Files\Enthought or home\AppData\Local\Enthought\Canopy\App for all users or per user respectively. Newer installations are updated by using the built in update tool. See their documentation.
   • ActiveState also uses an MSI so newer installations can be installed on top of older ones. See their installation notes.

     Other Python 2.7 Installations On Windows, ActivePython 2.7 cannot coexist with other Python 2.7 installations (for example, a Python 2.7 build from python.org). Uninstall any other Python 2.7 installations before installing ActivePython 2.7.

   • Sage recommends that you install it into a virtual machine, and provides a Oracle VirtualBox image file that can be used for this purpose. Upgrades are handled internally by issuing the sage -upgrade command.

   • Anaconda can be updated by using the conda command:

     conda update --all
     

     Anaconda/Miniconda lets users create environments to manage multiple Python versions including Python-2.6, 2.7, 3.3, 3.4 and 3.5. The root Anaconda/Miniconda installations are currently based on either Python-2.7 or Python-3.5.

     Anaconda will likely disrupt any other Python installations. Installation uses MSI installer. [UPDATE: 2016-05-16] Anaconda and Miniconda now use .exe installers and provide options to disable Windows PATH and Registry alterations.

     Therefore Anaconda/Miniconda can be installed without disrupting existing Python installations depending on how it was installed and the options that were selected during installation. If the .exe installer is used and the options to alter Windows PATH and Registry are not disabled, then any previous Python installations will be disabled, but simply uninstalling the Anaconda/Miniconda installation should restore the original Python installation, except maybe the Windows Registry Python\PythonCore keys.

     Anaconda/Miniconda makes the following registry edits regardless of the installation options: HKCU\Software\Python\ContinuumAnalytics\ with the following keys: Help, InstallPath, Modules and PythonPath - official Python registers these keys too, but under Python\PythonCore. Also uninstallation info is registered for Anaconda\Miniconda. Unless you select the "Register with Windows" option during installation, it doesn't create PythonCore, so integrations like Python Tools for Visual Studio do not automatically see Anaconda/Miniconda. If the option to register Anaconda/Miniconda is enabled, then I think your existing Python Windows Registry keys will be altered and uninstallation will probably not restore them.

   • WinPython updates, I think, can be handled through the WinPython Control Panel.
   • PortablePython is no longer being developed. It had no update method. Possibly updates could be unzipped into a fresh directory and then App\lib\site-packages and App\Scripts could be copied to the new installation, but if this didn't work then reinstalling all packages might have been necessary. Use pip list to see what packages were installed and their versions. Some were installed by PortablePython. Use easy_install pip to install pip if it wasn't installed.

2. If OP has 2.7.x and wants to install a different version, e.g. <=2.6.x or >=3.x.x, then installing different versions side-by-side is fine. You must choose which version of Python (if any) to associate with *.py files and which you want on your path, although you should be able to set up shells with different paths if you use BASH. AFAIK 2.7.x is backwards compatible with 2.6.x, so IMHO side-by-side installs is not necessary, however Python-3.x.x is not backwards compatible, so my recommendation would be to put Python-2.7 on your path and have Python-3 be an optional version by creating a shortcut to its executable called python3 (this is a common setup on Linux). The official Python default install path on Windows is

   • C:\Python33 for 3.3.x (latest 2013-07-29)
   • C:\Python32 for 3.2.x
   • &c.
   • C:\Python27 for 2.7.x (latest 2013-07-29)
   • C:\Python26 for 2.6.x
   • &c.

3. If OP is not updating Python, but merely updating packages, they may wish to look into virtualenv to keep the different versions of packages specific to their development projects separate. Pip is also a great tool to update packages. If packages use binary installers I usually uninstall the old package before installing the new one.

I hope this clears up any confusion.

Here is an idea as you may have multiple newline in a textbox:

 var text=document.getElementById('post-text').value.split('\n');
 var html = text.join('<br />');

This HTML value will preserve newline. Hope this helps.

The official guideline is there now. mgechev/angular2-seed had alignment with it too. see #857.

It is heavily suggested to make use of webpack when importing pictures from assets and in general for optimisation and pathing purposes

If you wish to load them by webpack you can simply use :src='require('path/to/file')' Make sure you use : otherwise it won't execute the require statement as Javascript.

In typescript you can do almost the exact same operation: :src="require('@/assets/image.png')"

Why the following is generally considered bad practice:

<template>
  <div id="app">
    <img src="./assets/logo.png">
  </div>
</template>

<script>
export default {
}
</script>

When building using the Vue cli, webpack is not able to ensure that the assets file will maintain a structure that follows the relative importing. This is due to webpack trying to optimize and chunk items appearing inside of the assets folder. If you wish to use a relative import you should do so from within the static folder and use: <img src="./static/logo.png">

There is the easy way

HTML:

<input type="checkbox" name="test[]" />x
<input type="checkbox" name="test[]"  />y
<input type="checkbox" name="test[]" />z
<button type="button" id="submit">Submit</button>

JQUERY:

$("#submit").on("click",function(){
    if (($("input[name*='test']:checked").length)<=0) {
        alert("You must check at least 1 box");
    }
    return true;
});

For this you not need any plugin. Enjoy;)

See the crypto.createHash() function and the associated hash.update() and hash.digest() functions:

var crypto = require('crypto')
var shasum = crypto.createHash('sha1')
shasum.update('foo')
shasum.digest('hex') // => "0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33"

As far as I know there is not an easy way to do this since Javascript/JQuery does not have access to the local filesystem. There are some new features in html 5 that allows you to check certain meta data such as file size but I'm not sure if you can actually get the image dimensions.

Here is an article I found regarding the html 5 features, and a work around for IE that involves using an ActiveX control. http://jquerybyexample.blogspot.com/2012/03/how-to-check-file-size-before-uploading.html

I use the following vanilla JavaScript functions in my code. They use regular expressions and indexOf but do not require quoting special characters in regular expressions.

function addClass(el, cn) {
    var c0 = (" " + el.className + " ").replace(/\s+/g, " "),
        c1 = (" " + cn + " ").replace(/\s+/g, " ");
    if (c0.indexOf(c1) < 0) {
        el.className = (c0 + c1).replace(/\s+/g, " ").replace(/^ | $/g, "");
    }
}

function delClass(el, cn) {
    var c0 = (" " + el.className + " ").replace(/\s+/g, " "),
        c1 = (" " + cn + " ").replace(/\s+/g, " ");
    if (c0.indexOf(c1) >= 0) {
        el.className = c0.replace(c1, " ").replace(/\s+/g, " ").replace(/^ | $/g, "");
    }
}

You can also use element.classList in modern browsers.

If you need access to the internal states of a function, you're possibly better off using a class. You can make a class instance behave like a function by making it a callable, which is done by defining __call__:

class StatefulFunction( object ):
    def __init__( self ):
        self.public_value = 'foo'

    def __call__( self ):
        return self.public_value


>> f = StatefulFunction()
>> f()
`foo`
>> f.public_value = 'bar'
>> f()
`bar`

SELECT YEAR(getdate()) * 10000 + MONTH(getdate()) * 100 + DAY(getdate())

CAST is standard SQL, but CONVERT is only for the dialect T-SQL. We have a small advantage for convert in the case of datetime.

With CAST, you indicate the expression and the target type; with CONVERT, there’s a third argument representing the style for the conversion, which is supported for some conversions, like between character strings and date and time values. For example, CONVERT(DATE, '1/2/2012', 101) converts the literal character string to DATE using style 101 representing the United States standard.

I assume that the main idea is to find if number is negative and display it in correct format.

For those who use PHP5.3 might be interested in using Number Formatter Class - http://php.net/manual/en/class.numberformatter.php. This function, as well as range of other useful things, can format your number.

$profitLoss = 25000 - 55000;

$a= new \NumberFormatter("en-UK", \NumberFormatter::CURRENCY); 
$a->formatCurrency($profitLoss, 'EUR');
// would display (€30,000.00)

Here also a reference to why brackets are used for negative numbers: http://www.open.edu/openlearn/money-management/introduction-bookkeeping-and-accounting/content-section-1.7

find {directory} -type f -name '*.extension'

Example: To find all csv files in the current directory and its sub-directories, use:

find . -type f -name '*.csv'

To add to Brian Diggs answer.

another way using grepl will return a data frame containing all your values.

toMatch <- myfile$Letter

matches <- myfile[grepl(paste(toMatch, collapse="|"), myfile$Letter), ]

matches

Letter Firstname
1     A1      Alex 
2     A6      Alex 
4     A1       Bob 
5     A9     Chris 
6     A6     Chris

Maybe a bit cleaner... maybe?

Because the interpreter is not a shell where you provide commands, it's - well - an interpreter. The things that you give to it are Python code.

The syntax of Python is such that exit, by itself, cannot possibly be anything other than a name for an object. Simply referring to an object can't actually do anything (except what the read-eval-print loop normally does; i.e. display a string representation of the object).

C# in .NET 3.5 using System.DirectoryServices.AccountManagement.

 bool valid = false;
 using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
 {
     valid = context.ValidateCredentials( username, password );
 }

This will validate against the current domain. Check out the parameterized PrincipalContext constructor for other options.

The EF Core doesn't create DBset for the SQL views automatically in the context calss, we can add them manually as below.

public partial class LocalDBContext : DbContext
{ 

    public LocalDBContext(DbContextOptions<LocalDBContext> options) : base(options)
    {

    }

    public virtual DbSet<YourView> YourView { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<YourView>(entity => {
            entity.HasKey(e => e.ID);
            entity.ToTable("YourView");
            entity.Property(e => e.Name).HasMaxLength(50);
        });
    }

}

The sample view is defined as below with few properties

using System;
using System.Collections.Generic;

namespace Project.Entities
{
    public partial class YourView
    {
        public string Name { get; set; }
        public int ID { get; set; }
    }
}

After adding a class for the view and DB set in the context class, you are good to use the view object through your context object in the controller.

You may use also

select * from pg_tables where schemaname = 'information_schema'

In generall pg* tables allow you to see everything in the db, not constrained to your permissions (if you have access to the tables of course).

I was having a similar issue as my breakpoints in project(B) were not being hit. My solution was to rebuild project(B) then debug project(A) as the dlls needed to be updated.

Visual studio should allow you to debug into an external library.

The default constructor has no arguments. You need to specify a constructor:

    public Friends( String firstName, String age) { ... }

list is slower than arrays.If you need efficiency use arrays.If you need flexibility use list.

There are several issues:

1. elif option == 2: and the subsequent elif-else should be aligned with the second if option == 1, not with the for.

2. The for x in range(x, 1, 1): is missing a body.

3. Since "option 1 (count)" requires a second input, you need to call input() for the second time. However, for sanity's sake I urge you to store the result in a second variable rather than repurposing option.

4. The comparison in the first line of your code is probably meant to be an assignment.

You'll discover more issues once you're able to run your code (you'll need a couple more input() calls, one of the range() calls will need attention etc).

Lastly, please don't use the same variable as the loop variable and as part of the initial/terminal condition, as in:

            for x in range(1, x, 1):
                print x

It may work, but it is very confusing to read. Give the loop variable a different name:

            for i in range(1, x, 1):
                print i

Either two different IP addresses (like recommended) or one web server is reverse-proxying the other (which is listening on a port <>80).

For instance: Apache listens on port 80, IIS on port 8080. Every http request goes to Apache first (of course). You can then decide to forward every request to a particular (named virtual) domain or every request that contains a particular directory (e.g. http://www.example.com/winapp/) to the IIS.

Advantage of this concept is that you have only one server listening to the public instead of two, you are more flexible as with two distinct servers.

Drawbacks: some webapps are crappily designed and a real pain in the ass to integrate into a reverse-proxy infrastructure. A working IIS webapp is dependent on a working Apache, so we have some inter-dependencies.

def valid = pointAddress.findAll { a ->
    validPointTypes.any { a.contains(it) }
}

Should do it

Call this function onclick of button

/*pass whatever you want instead of id */
function doConfirm(id) {
    var ok = confirm("Are you sure to Delete?");
    if (ok) {
        if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        } else {
            // code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }

        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                window.location = "create_dealer.php";
            }
        }

        xmlhttp.open("GET", "delete_dealer.php?id=" + id);
        // file name where delete code is written
        xmlhttp.send();
    }
}

You are looking for System.Environment.NewLine.

On Windows, this is equivalent to \r\n though it could be different under another .NET implementation, such as Mono on Linux, for example.

You should have if row[2] != "0". Otherwise it's not checking to see if the string value is equal to 0.

In my case I have succeed with the following solution for converting field ClockInTime from ClockTime collection from string to Date type:

db.ClockTime.find().forEach(function(doc) { 
    doc.ClockInTime=new Date(doc.ClockInTime);
    db.ClockTime.save(doc); 
    })

I face this problem too when making new project from android studio.

I've been able to resolve this by downgrading buildToolsVersion in app gradle setting: change {module-name}/build.gradle line

buildToolsVersion "24.0.0 rc1"

to

buildToolsVersion "23.0.3"

@Edit:
In Android Studio 2.1 Go to File-> Project Structure->App -> Build Tool Version. Change it to 23.0.3

Do the method above, only when you are using java version 7 and for some reason do not want to upgrade to java 8 yet.

Hope this helps

It is not too surprising: the execution plan for the tiny insert is computed once, and then reused 1000 times. Parsing and preparing the plan is quick, because it has only four values to del with. A 1000-row plan, on the other hand, needs to deal with 4000 values (or 4000 parameters if you parameterized your C# tests). This could easily eat up the time savings you gain by eliminating 999 roundtrips to SQL Server, especially if your network is not overly slow.

int[] b = new int[] { 1, 2, 3, 4, 5 };            
int j;
for(int i=0;i<b.Length;i++)
{
  int prod = 1;
  int s = b[i];
  for(j=i;j<b.Length-1;j++)
  {
    prod = prod * b[j + 1];
  }
int pos = i;    
while(pos!=-1)
{
  pos--;
  if(pos!=-1)
     prod = prod * b[pos];                    
}
Console.WriteLine("\n Output is {0}",prod);
}

ProgressBar bar;

private Handler progressBarHandler = new Handler();

GradientDrawable progressGradientDrawable = new GradientDrawable(
        GradientDrawable.Orientation.LEFT_RIGHT, new int[]{
                0xff1e90ff,0xff006ab6,0xff367ba8});
ClipDrawable progressClipDrawable = new ClipDrawable(
        progressGradientDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
Drawable[] progressDrawables = {
        new ColorDrawable(0xffffffff),
        progressClipDrawable, progressClipDrawable};
LayerDrawable progressLayerDrawable = new LayerDrawable(progressDrawables);


int status = 0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // TODO Auto-generated method stub
    setContentView(R.layout.startup);

    bar = (ProgressBar) findViewById(R.id.start_page_progressBar);
    bar.setProgress(0);
    bar.setMax(100);

    progressLayerDrawable.setId(0, android.R.id.background);
    progressLayerDrawable.setId(1, android.R.id.secondaryProgress);
    progressLayerDrawable.setId(2, android.R.id.progress);

    bar.setProgressDrawable(progressLayerDrawable);
}

This helped me to set a custom color to progressbar through code. Hope it helps

As has been said, using unset is different with arrays as well

$ foo=(4 5 6)

$ foo[2]=

$ echo ${#foo[*]}
3

$ unset foo[2]

$ echo ${#foo[*]}
2

I found a difference when creating a Form Contact: slim (recommended by boostrap 4.5):

• After sending an email the global variables get stuck, and that makes if the user gives f5 (reload page) it is sent again. min:
• The previous error will be solved. how i suffered!

I had a problem similar to the one posed in the original question. I was intrigued by the divs styled as table elements (didn't know you could do that!) and gave it a run. However, my solution was to keep my tables wrapped in tags, but rename each input and select option to become the keys of array, which I'm now parsing to get each element in the selected row.

Here's a single row from the table. Note that key [4] is the rendered ID of the row in the database from which this table row was retrieved:

<table>
  <tr>
    <td>DisabilityCategory</td>
    <td><input type="text" name="FormElem[4][ElemLabel]" value="Disabilities"></td>
    <td><select name="FormElem[4][Category]">
        <option value="1">General</option>
        <option value="3">Disability</option>
        <option value="4">Injury</option>
        <option value="2"selected>School</option>
        <option value="5">Veteran</option>
        <option value="10">Medical</option>
        <option value="9">Supports</option>
        <option value="7">Residential</option>
        <option value="8">Guardian</option>
        <option value="6">Criminal</option>
        <option value="11">Contacts</option>
      </select></td>
    <td>4</td>
    <td style="text-align:center;"><input type="text" name="FormElem[4][ElemSeq]" value="0" style="width:2.5em; text-align:center;"></td>
    <td>'ccpPartic'</td>
    <td><input type="text" name="FormElem[4][ElemType]" value="checkbox"></td>
    <td><input type="checkbox" name="FormElem[4][ElemRequired]"></td>
    <td><input type="text" name="FormElem[4][ElemLabelPrefix]" value=""></td>
    <td><input type="text" name="FormElem[4][ElemLabelPostfix]" value=""></td>
    <td><input type="text" name="FormElem[4][ElemLabelPosition]" value="before"></td>
    <td><input type="submit" name="submit[4]" value="Commit Changes"></td>
  </tr>
</table>

Then, in PHP, I'm using the following method to store in an array ($SelectedElem) each of the elements in the row corresponding to the submit button. I'm using print_r() just to illustrate:

$SelectedElem = implode(",", array_keys($_POST['submit']));
print_r ($_POST['FormElem'][$SelectedElem]);

Perhaps this sounds convoluted, but it turned out to be quite simple, and it preserved the organizational structure of the table.

Other instance of preserving the order or sort by descending:

In [97]: import pandas as pd                                                                                                    

In [98]: df = pd.DataFrame({'name':['A','B','C','A','B','C','A','B','C'],'Year':[2003,2002,2001,2003,2002,2001,2003,2002,2001]})

#### Default groupby operation:
In [99]: for each in df.groupby(["Year"]): print each

### order preserved:

(2001,    Year name
2  2001    C

8  2001    C)

In [106]: df.groupby(["Year"], sort=False).apply(lambda x: x.sort_values(["Year"]))

You can use the following if you want to specify tricky formats:

df['date_col'] =  pd.to_datetime(df['date_col'], format='%d/%m/%Y')

More details on format here:

• Python 2 https://docs.python.org/2/library/datetime.html#strftime-strptime-behavior
• Python 3 https://docs.python.org/3.7/library/datetime.html#strftime-strptime-behavior

Another reference: If you are using the maven-jaxb2-plugin, prior to version 0.9.0, you can use the workaround described on this issue, in which this behaviour affected the plugin.

I got tricked by a selection matching multiple items so each was clicked. :first helped:

$('.someClass[data-foo="'+notAlwaysUniqueID+'"]:first').click();

Look at the following:

echo "ls -l" | at 07:00

This code line executes "ls -l" at a specific time. This is an example of executing something (a command in my example) at a specific time. "at" is the command you were really looking for. You can read the specifications here:

http://manpages.ubuntu.com/manpages/precise/en/man1/at.1posix.html http://manpages.ubuntu.com/manpages/xenial/man1/at.1posix.html

Hope it helps!

I believe the sprintf is the right function for you. I's in the standard library, like printf. Follow the link below for more information:

http://www.cplusplus.com/reference/clibrary/cstdio/sprintf/

For the low-level x86 specific solution use the x86 TEST opcode.

Your compiler should turn _bittest into this though...

You can do that using count:

my_dict = {i:MyList.count(i) for i in MyList}

>>> print my_dict     #or print(my_dict) in python-3.x
{'a': 3, 'c': 3, 'b': 1}

Or using collections.Counter:

from collections import Counter

a = dict(Counter(MyList))

>>> print a           #or print(a) in python-3.x
{'a': 3, 'c': 3, 'b': 1}

A portable way to do this is to call the function through a pointer:

void (*foo_ptr)() = foo;
foo_ptr();

Though this produces different instructions to branch, which may not be your goal. Which brings up a good point: what is your goal here?

$res = explode("\n",wordwrap('12345678910', 8, "...\n",true))[0];

// $res will be  : "12345678..."

Here's another way:

Option Explicit

' Just a little test stub. 
Sub Tester()

    Dim pList(500) As Integer
    Dim i As Integer

    For i = 0 To UBound(pList)

        pList(i) = 500 - i

    Next i

    MsgBox "Value 18 is at array position " & FindInArray(pList, 18) & "."
    MsgBox "Value 217 is at array position " & FindInArray(pList, 217) & "."
    MsgBox "Value 1001 is at array position " & FindInArray(pList, 1001) & "."

End Sub

Function FindInArray(pList() As Integer, value As Integer)

    Dim i As Integer
    Dim FoundValueLocation As Integer

    FoundValueLocation = -1

    For i = 0 To UBound(pList)

        If pList(i) = value Then

            FoundValueLocation = i
            Exit For

        End If

    Next i

    FindInArray = FoundValueLocation

End Function

If you want to compare image for similarity,I suggest you to used OpenCV. In OpenCV, there are few feature matching and template matching. For feature matching, there are SURF, SIFT, FAST and so on detector. You can use this to detect, describe and then match the image. After that, you can use the specific index to find number of match between the two images.

I've run into a couple gotchas with the accepted answer. Here is my solution.

import copy

def clone(instance):
    cloned = copy.copy(instance) # don't alter original instance
    cloned.pk = None
    try:
        delattr(cloned, '_prefetched_objects_cache')
    except AttributeError:
        pass
    return cloned

Note: this uses solutions that aren't officially sanctioned in the Django docs, and they may cease to work in future versions. I tested this in 1.9.13.

The first improvement is that it allows you to continue using the original instance, by using copy.copy. Even if you don't intend to reuse the instance, it can be safer to do this step if the instance you're cloning was passed as an argument to a function. If not, the caller will unexpectedly have a different instance when the function returns.

copy.copy seems to produce a shallow copy of a Django model instance in the desired way. This is one of the things I did not find documented, but it works by pickling and unpickling, so it's probably well-supported.

Secondly, the approved answer will leave any prefetched results attached to the new instance. Those results shouldn't be associated with the new instance, unless you explicitly copy the to-many relationships. If you traverse the the prefetched relationships, you will get results that don't match the database. Breaking working code when you add a prefetch can be a nasty surprise.

Deleting _prefetched_objects_cache is a quick-and-dirty way to strip away all prefetches. Subsequent to-many accesses work as if there never was a prefetch. Using an undocumented property that begins with an underscore is probably asking for compatibility trouble, but it works for now.

We can also do this using randint.

from random import randint
l= ['a','b','c']

def get_rand_element(l):
    if l:
        return l[randint(0,len(l)-1)]
    else:
        return None

get_rand_element(l)

You can use the built-in ast.literal_eval:

>>> import ast
>>> ast.literal_eval("{'muffin' : 'lolz', 'foo' : 'kitty'}")
{'muffin': 'lolz', 'foo': 'kitty'}

This is safer than using eval. As its own docs say:

>>> help(ast.literal_eval)
Help on function literal_eval in module ast:

literal_eval(node_or_string)
    Safely evaluate an expression node or a string containing a Python
    expression.  The string or node provided may only consist of the following
    Python literal structures: strings, numbers, tuples, lists, dicts, booleans,
    and None.

For example:

>>> eval("shutil.rmtree('mongo')")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
  File "/opt/Python-2.6.1/lib/python2.6/shutil.py", line 208, in rmtree
    onerror(os.listdir, path, sys.exc_info())
  File "/opt/Python-2.6.1/lib/python2.6/shutil.py", line 206, in rmtree
    names = os.listdir(path)
OSError: [Errno 2] No such file or directory: 'mongo'
>>> ast.literal_eval("shutil.rmtree('mongo')")
Traceback (most recent call last):

  File "/opt/Python-2.6.1/lib/python2.6/ast.py", line 68, in literal_eval
    return _convert(node_or_string)

    raise ValueError('malformed string')

In the SQL standard, DROP table removes the table and the table schema - TRUNCATE removes all rows.

You can bind listeners to one common functions -

$(window).bind("load resize scroll",function(e){
  // do stuff
});

Or another way -

$(window).bind({
     load:function(){

     },
     resize:function(){

     },
     scroll:function(){

    }
});

Alternatively, instead of using .bind() you can use .on() as bind directly maps to on(). And maybe .bind() won't be there in future jquery versions.

$(window).on({
     load:function(){

     },
     resize:function(){

     },
     scroll:function(){

    }
});

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

If your bottleneck is the disk, it matters how you read from it. dd if=filename bs=128M | wc -l is a lot faster than wc -l filename or cat filename | wc -l for my machine that has an HDD and fast CPU and RAM. You can play around with the block size and see what dd reports as the throughput. I cranked it up to 1GiB.

Note: There is some debate about whether cat or dd is faster. All I claim is that dd can be faster, depending on the system, and that it is for me. Try it for yourself.

Another option is to use numpy.full, an option available in NumPy 1.8+

a = np.full([height, width, 9], np.nan)

This is pretty flexible and you can fill it with any other number that you want.

1. Shared preferences: android shared preferences example for high scores?

2. Does your application has an access to the "external Storage Media". If it does then you can simply write the value (store it with timestamp) in a file and save it. The timestamp will help you in showing progress if thats what you are looking for. {not a smart solution.}

You can implement throwing exceptions on mysql query fail on your own. What you need is to write a wrapper for mysql_query function, e.g.:

// user defined. corresponding MySQL errno for duplicate key entry
const MYSQL_DUPLICATE_KEY_ENTRY = 1022;

// user defined MySQL exceptions
class MySQLException extends Exception {}
class MySQLDuplicateKeyException extends MySQLException {}

function my_mysql_query($query, $conn=false) {
    $res = mysql_query($query, $conn);
    if (!$res) {
        $errno = mysql_errno($conn);
        $error = mysql_error($conn);
        switch ($errno) {
        case MYSQL_DUPLICATE_KEY_ENTRY:
            throw new MySQLDuplicateKeyException($error, $errno);
            break;
        default:
            throw MySQLException($error, $errno);
            break;
        }
    }
    // ...
    // doing something
    // ...
    if ($something_is_wrong) {
        throw new Exception("Logic exception while performing query result processing");
    }

}

try {
    mysql_query("INSERT INTO redirects SET ua_string = '$ua_string'")
}
catch (MySQLDuplicateKeyException $e) {
    // duplicate entry exception
    $e->getMessage();
}
catch (MySQLException $e) {
    // other mysql exception (not duplicate key entry)
    $e->getMessage();
}
catch (Exception $e) {
    // not a MySQL exception
    $e->getMessage();
}

It depends on what type of fading you are looking for.

But with shadow and rounded corners you can get a nice result. Rounded corners because the bigger the shadow, the weirder it will look in the edges unless you balance it out with rounded corners.

Here are the steps that worked for me after logging into the box:

Locate MySQL configuration file:

$ mysql --help | grep -A 1 "Default options"

Default options are read from the following files in the given order: /etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf

On Ubuntu 16, the path is typically /etc/mysql/mysql.conf.d/mysqld.cnf

Change configuration file for bind-address:

If it exists, change the value as follows. If it doesn't exist, add it anywhere in the [mysqld] section.

bind-address = 0.0.0.0

Save your changes to the configuration file and restart the MySQL service.

service mysql restart

Create / Grant access to database user:

Connect to the MySQL database as the root user and run the following SQL commands:

mysql> CREATE USER 'username'@'%' IDENTIFIED BY 'password';

mysql> GRANT ALL PRIVILEGES ON mydb.* TO 'username'@'%';

In batch, the > is a redirection sign used to output data into a text file. The compare op's available (And recommended) for cmd are below (quoted from the if /? help):

where compare-op may be one of:

    EQU - equal
    NEQ - not equal
    LSS - less than
    LEQ - less than or equal
    GTR - greater than
    GEQ - greater than or equal

That should explain what you want. The only other compare-op is == which can be switched with the if not parameter. Other then that rely on these three letter ones.

Based on @AlecRust idea, I did an implementation of png text service.

The demo is here:

http://lingtalfi.com/services/pngtext?color=cc0000&size=10&text=Hello%20World

There are four parameters:

• text: the string to display
• font: not use because I only have Arial.ttf anyway on this demo.
• fontSize: an integer (defaults to 12)
• color: a 6 chars hexadecimal code

Please do not use this service directly (except for testing), but use the class I created that provides the service:

https://github.com/lingtalfi/WebBox/blob/master/Image/PngTextUtil.php

class PngTextUtil
{
    /**

        imagepng($logoimg); //save your image at new location $target
        imagedestroy($logoimg);
    }
}

Note: if you don't use the universe framework, you will need to replace this line:

$rgbColors = ConvertTool::convertHexColorToRgb($hexColor);

With this code:

$rgbColors = sscanf($hexColor, "%02x%02x%02x");

In which case your hex color must be exactly 6 chars long (don't put the hash symbol (#) in front of it).

Note: in the end, I did not use this service, because I found that the font was ugly and worse: it was not possible to select the text. But for the sake of this discussion I thought this code was worth sharing...

Use below to check file's size and clear if it's greater,

    $("input[type='file']").on("change", function () {
     if(this.files[0].size > 2000000) {
       alert("Please upload file less than 2MB. Thanks!!");
       $(this).val('');
     }
    });

To do POST you'll need to have a form.

<form action="employee.action" method="post">
    <input type="submit" value="Employee1" />
</form>

There are some ways to post data with hyperlinks, but you'll need some javascript, and a form.

Some tricks: Make a link use POST instead of GET and How do you post data with a link

Edit: to load response on a frame you can target your form to your frame:

<form action="employee.action" method="post" target="myFrame">

Ok, actually the answer is way simple: when there is a option not recognized by Angular, it includes a dull one. What you are doing wrong is, when you use ng-options, it reads an object, say [{ id: 10, name: test }, { id: 11, name: test2 }] right?

This is what your model value needs to be to evaluate it as equal, say you want selected value to be 10, you need to set your model to a value like { id: 10, name: test } to select 10, therefore it will NOT create that trash.

Hope it helps everybody to understand, I had a rough time trying :)

Here's what worked for me. Note: Adding the image within a row introduces some space so I've intentionally used only a div to encapsulate the image.

<div class="container-fluid w-100 h-auto m-0 p-0">  

    <img src="someimg.jpg" class="img-fluid w-100 h-auto p-0 m-0" alt="Patience">           

</div>

If you want to just compare dates,

yourdatetime.date() < datetime.today().date()

Or, obviously,

yourdatetime.date() == datetime.today().date()

If you want to check that they're the same date.

The documentation is usually helpful. It is also usually the first google result for python thing_i_have_a_question_about. Unless your question is about a function/module named "snake".

Basically, the datetime module has three types for storing a point in time:

• date for year, month, day of month
• time for hours, minutes, seconds, microseconds, time zone info
• datetime combines date and time. It has the methods date() and time() to get the corresponding date and time objects, and there's a handy combine function to combine date and time into a datetime.

I tried what Samuel Slade has suggested. Didn't work for me. The PropertyInfo list was coming as empty. So, I tried the following and it worked for me.

    Type type = typeof(Record);
    FieldInfo[] properties = type.GetFields();
    foreach (FieldInfo property in properties) {

Your code is calling the function and assigning the return value to onClick, also it should be 'onclick'. This is how it should look.

document.getElementById("a").onclick = Bar;

Looking at your other code you probably want to do something like this:

document.getElementById(id+"Button").onclick = function() { HideError(id); }

You should use the key() function.

key($array)

should return the current key.

If you need the position of the current key:

array_search($key, array_keys($array));

I don't think you can do this with CSS. Instead, at regular 'word lengths' along the string, insert an HTML soft-hyphen:

ACTGATCG­AGCTGAAG­CGCAGTGC­GATGCTTC­GATGATGC­TGACGATG

This will display a hyphen at the end of the line, where it wraps, which may or may not be what you want.

Note Safari seems to wrap the long string in a <textarea> anyway, unlike Firefox.

I had the same problem - my scenario was that I was referencing the new System.Web.Mvc.dll from a lib folder and I did not have "Copy Local" set to true. The application was then reverting back to the version in the GAC which didn't have the correct namespaces (Html, Ajax etc) in it and was giving me the run time error.
