I would definitely use:

try
{
    //some code
}
catch
{
    //you should totally do something here, but feel free to rethrow
    //if you need to send the exception up the stack.
    throw;
}

That will preserve your stack.

I suggest using Hits's answer, but adding a Locale format, this is how Android Developers recommends:

try {
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.getDefault());
        return dateFormat.format(new Date()); // Find todays date
    } catch (Exception e) {
        e.printStackTrace();

        return null;
    }

If you are already using jQuery UI in your project, you can use the built-in datepicker method for formatting your date object:

$.datepicker.formatDate('yy-mm-dd', new Date(2007, 1 - 1, 26));

However, the datepicker only formats dates, and cannot format times.

Have a look at jQuery UI datepicker formatDate, the examples.

I got here searching for a way to execute some code whenever the program ends.
Found this:

Kernel.at_exit { puts "sayonara" }
# do whatever
# [...]
# call #exit or #abort or just let the program end
# calling #exit! will skip the call

Called multiple times will register multiple handlers.

$newstr = preg_replace('/[^a-zA-Z0-9\']/', '_', "There wouldn't be any");
$newstr = str_replace("'", '', $newstr);

I put them on two separate lines to make the code a little more clear.

Note: If you're looking for Unicode support, see Filip's answer below. It will match all characters that register as letters in addition to A-z.

Async Arrow function syntax with parameters

const myFunction = async (a, b, c) => {
   // Code here
}

Well if you want to use java.util.Date only, here is a small trick you can use:

String dateString = Long.toString(Date.UTC(date.getYear(), date.getMonth(), date.getDate(), date.getHours(), date.getMinutes(), date.getSeconds()));

this will works on MySQL to drop constraints

alter table tablename drop primary key;

alter table tablename drop foreign key;

A simple definition would be an HTTP request that acts like a normal method call; i.e., it accepts parameters and returns a structured result, usually XML, that can be deserialized into an object(s).

I know this post was about 11g, but a bug in the 12c client with how it encrypts passwords may be to blame for this error if you decide to use that one and you:

• Don't have the password case-sensitivity issue (i.e. you tried ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = FALSE and resetting the password and still doesn't work),
• Put quotes around your password in your connection string and it still doesn't help,
• You've verified all of your environmental variables (ORACLE_HOME, PATH, TNS_ADMIN), and the TNS_ADMIN registry string at HKLM\Software\Oracle\KEY_OraClient12Home is in place,
• You've verified your connection string and user name/password combination works in Net Manager, and
• You can connect using SQL*Plus, Oracle SQL Developer using the same credentials.

All the basic checks.

Fix: Try setting HKLM\System\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy\Enabled to 0 in the registry (regedit) to disable FIPS.

I came to this solution and it did not worked for me! Because I was using 64bit I had to replace the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

Instead of the one that everyone talks about:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]

Update

With ES6, this is possible in exactly the manner you have described; a detailed description can be found in the documentation.

Old answer

Default parameters in JavaScript can be implemented in mainly two ways:

function myfunc(a, b)
{
    // use this if you specifically want to know if b was passed
    if (b === undefined) {
        // b was not passed
    }
    // use this if you know that a truthy value comparison will be enough
    if (b) {
        // b was passed and has truthy value
    } else {
        // b was not passed or has falsy value
    }
    // use this to set b to a default value (using truthy comparison)
    b = b || "default value";
}

The expression b || "default value" evaluates the value AND existence of b and returns the value of "default value" if b either doesn't exist or is falsy.

Alternative declaration:

function myfunc(a)
{
    var b;

    // use this to determine whether b was passed or not
    if (arguments.length == 1) {
        // b was not passed
    } else {
        b = arguments[1]; // take second argument
    }
}

The special "array" arguments is available inside the function; it contains all the arguments, starting from index 0 to N - 1 (where N is the number of arguments passed).

This is typically used to support an unknown number of optional parameters (of the same type); however, stating the expected arguments is preferred!

Further considerations

Although undefined is not writable since ES5, some browsers are known to not enforce this. There are two alternatives you could use if you're worried about this:

b === void 0;
typeof b === 'undefined'; // also works for undeclared variables

I would like to add a word of warning when you are dealing with C++11-style allocator-aware containers. Swapping and assignment have subtly different semantics.

For concreteness, let us consider a container std::vector<T, A>, where A is some stateful allocator type, and we'll compare the following functions:

void fs(std::vector<T, A> & a, std::vector<T, A> & b)
{ 
    a.swap(b);
    b.clear(); // not important what you do with b
}

void fm(std::vector<T, A> & a, std::vector<T, A> & b)
{
    a = std::move(b);
}

The purpose of both functions fs and fm is to give a the state that b had initially. However, there is a hidden question: What happens if a.get_allocator() != b.get_allocator()? The answer is: It depends. Let's write AT = std::allocator_traits<A>.

• If AT::propagate_on_container_move_assignment is std::true_type, then fm reassigns the allocator of a with the value of b.get_allocator(), otherwise it does not, and a continues to use its original allocator. In that case, the data elements need to be swapped individually, since the storage of a and b is not compatible.

• If AT::propagate_on_container_swap is std::true_type, then fs swaps both data and allocators in the expected fashion.

• If AT::propagate_on_container_swap is std::false_type, then we need a dynamic check.

  • If a.get_allocator() == b.get_allocator(), then the two containers use compatible storage, and swapping proceeds in the usual fashion.
  • However, if a.get_allocator() != b.get_allocator(), the program has undefined behaviour (cf. [container.requirements.general/8].

The upshot is that swapping has become a non-trivial operation in C++11 as soon as your container starts supporting stateful allocators. That's a somewhat "advanced use case", but it's not entirely unlikely, since move optimizations usually only become interesting once your class manages a resource, and memory is one of the most popular resources.

here is how to create UILabel Programmatically..

1) Write this in .h file of your project.

UILabel *label;

2) Write this in .m file of your project.

label=[[UILabel alloc]initWithFrame:CGRectMake(10, 70, 50, 50)];//Set frame of label in your viewcontroller.
[label setBackgroundColor:[UIColor lightGrayColor]];//Set background color of label.
[label setText:@"Label"];//Set text in label.
[label setTextColor:[UIColor blackColor]];//Set text color in label.
[label setTextAlignment:NSTextAlignmentCenter];//Set text alignment in label.
[label setBaselineAdjustment:UIBaselineAdjustmentAlignBaselines];//Set line adjustment.
[label setLineBreakMode:NSLineBreakByCharWrapping];//Set linebreaking mode..
[label setNumberOfLines:1];//Set number of lines in label.
[label.layer setCornerRadius:25.0];//Set corner radius of label to change the shape.
[label.layer setBorderWidth:2.0f];//Set border width of label.
[label setClipsToBounds:YES];//Set its to YES for Corner radius to work.
[label.layer setBorderColor:[UIColor blackColor].CGColor];//Set Border color.
[self.view addSubview:label];//Add it to the view of your choice. 

Try this instead:

First, fix the line ending problem: (Notepad++ doesn't allow multi-line regular expressions)

Search [Extended Mode]: \r\n> (Or your own system's line endings)

Replace: >

then

Search [Regex Mode]: <option[^>]+value="([^"]+)"[^>]*>.*

(if you want all occurences of value rather than just the options, simple remove the leading option)

Replace: \1

Explanation of the second regular expression:

<option[^>]+     Find a < followed by "option" followed by 
                 at least one character which is not a >

value="          Find the string value="

([^"]+)          Find one or more characters which are not a " and save them
                 to group \1

"[^>]*>.*        Find a " followed by zero or more non-'>' characters
                 followed by a > followed by zero or more characters.

Yes, it's parsing HTML with a regex -- these warnings apply -- check the output carefully.

Following code works..

datePickerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(0);
        }
    });

@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
    return new DatePickerDialog(this, datePickerListener, year, month, day);
}

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        day = selectedDay;
        month = selectedMonth;
        year = selectedYear;
        datePickerButton.setText(selectedDay + " / " + (selectedMonth + 1) + " / "
                + selectedYear);
    }
};

You want your change to sit on top of the current state of the remote branch. So probably you want to pull right before you commit yourself. After that, push your changes again.

"Dirty" local files are not an issue as long as there aren't any conflicts with the remote branch. If there are conflicts though, the merge will fail, so there is no risk or danger in pulling before committing local changes.

Update: this will not work on iOS 7. You should use ASIdentifierManager.

HTML Table row heights will typically change proportionally to the table height, if the table height is larger than the height of your rows. Since the table is forcing the height of your rows, you can remove the table height to resolve the issue. If this is not acceptable, you can also give the rows explicit height, and add a third row that will auto size to the remaining table height.

Another option in CSS2 is the Max-Height Property, although it may lead to strange behavior in a table.http://www.w3schools.com/cssref/pr_dim_max-height.asp

.

I only see one color being specified (albeit you specify it in two different places.) Either you've omitted some of your style rules, or you simply didn't specify another color.

If you want to pack a struct with a value <255 (one byte unsigned, uint8_t) and end up with a string of one character, you're probably looking for the format B instead of c. C converts a character to a string (not too useful by itself) while B converts an integer.

struct.pack('B', 65)

(And yes, 65 is \x41, not \x65.)

The struct class will also conveniently handle endianness for communication or other uses.

$('#my_select').get(0).selectedIndex = 1;

But, In my opinion, the better way is using HTML only (with <input type="reset" />):

<form>
    <select id="my_select">
        <option value="a">a</option>
        <option value="b" selected="selected">b</option>
        <option value="c">c</option>
    </select>
    <input type="reset" value="reset" />
</form>

Yea these are great if your using a simple ORM like Dapper.

If your using .Net you can generate an XSD file at run time with any DataSet using the WriteXmlSchema method. http://msdn.microsoft.com/en-us/library/xt7k72x8(v=vs.110).aspx

Like this:

using (SqlConnection cnn = new SqlConnection(mConnStr)) {
DataSet Data = new DataSet();
cnn.Open();
string sql = "SELECT * FROM Person";

using (SqlDataAdapter Da = new SqlDataAdapter(sql, cnn))
{
try
{
    Da.Fill(Data);
    Da.TableMappings.Add("Table", "Person");
    Data.WriteXmlSchema(@"C:\Person.xsd");
}
catch (Exception ex)
{ MessageBox.Show(ex.Message); }
}
cnn.Close();

From there you can use xsd.exe to create a class that's XML serializable from the Developer Command Prompt. http://msdn.microsoft.com/en-us/library/x6c1kb0s(v=vs.110).aspx

like this:

xsd C:\Person.xsd /classes /language:CS

If you have a Red Hat server use yum. apt-get is only for Debian, Ubuntu and some other related linux.

For any special characters you should use '\'. So, for matching parentheses - /\(/

Using @EmbeddableId for the PK entity has solved my issue.

@Entity

 public class SampleEntity implements Serializable{

If you want to click on all checkboxes at once, a method like this will do:

private void ClickAllCheckboxes()
{
    foreach (IWebElement e in driver.FindElements(By.xpath("//input[@type='checkbox']")))
    {
        if(!e.Selected)
            e.Click();
    }
}

I think you should be able to use a default route handler and redirect from there to a page outside the app, as detailed below:

const ROUTER_INSTANCE = new VueRouter({
    mode: "history",
    routes: [
        { path: "/", component: HomeComponent },
        // ... other routes ...
        // and finally the default route, when none of the above matches:
        { path: "*", component: PageNotFound }
    ]
})

In the above PageNotFound component definition, you can specify the actual redirect, that will take you out of the app entirely:

Vue.component("page-not-found", {
    template: "",
    created: function() {
        // Redirect outside the app using plain old javascript
        window.location.href = "/my-new-404-page.html";
    }
}

You may do it either on created hook as shown above, or mounted hook also.

Please note:

1. I have not verified the above. You need to build a production version of app, ensure that the above redirect happens. You cannot test this in vue-cli as it requires server side handling.

2. Usually in single page apps, server sends out the same index.html along with app scripts for all route requests, especially if you have set <base href="/">. This will fail for your /404-page.html unless your server treats it as a special case and serves the static page.

Let me know if it works!

Update for Vue 3 onward:

You'll need to replace the '*' path property with '/:pathMatch(.*)*' if you're using Vue 3 as the old catch-all path of '*' is no longer supported. The route would then look something like this:

{ path: '/:pathMatch(.*)*', component: PathNotFound },

See the docs for more info on this update.

If your threads don't do I/O, synchronization, etc., and there's nothing else running, 1 thread per core will get you the best performance. However that very likely not the case. Adding more threads usually helps, but after some point, they cause some performance degradation.

Not long ago, I was doing performance testing on a 2 quad-core machine running an ASP.NET application on Mono under a pretty decent load. We played with the minimum and maximum number of threads and in the end we found out that for that particular application in that particular configuration the best throughput was somewhere between 36 and 40 threads. Anything outside those boundaries performed worse. Lesson learned? If I were you, I would test with different number of threads until you find the right number for your application.

One thing for sure: 4k threads will take longer. That's a lot of context switches.

Although this is not a built in Unix solution, I've implemented a solution for this using a shell script that can be included in whatever shell script you are using. This is usable on POSIX compliant setups. (sh, bash, ksh, zsh) The full description is available in the github repo -> https://github.com/plyint/encpass.sh. This solution will auto-generate a key for your script and store the key and your password (or other secrets) in a hidden directory under your user (i.e. ~/.encpass).

In your script you just need to source encpass.sh and then call the get_secret method. For example:

#!/bin/sh
. encpass.sh
password=$(get_secret)

Pasted below is lite version of the code for encpass.sh(you can get the full version over on github) for easier visibility:

 # inadvertently be sent to or discovered by an individual at a later date.
 #
 # This script generates an AES 256 bit symmetric key for each script (or user-
 # defined bucket) that stores secrets.  This key will then be used to encrypt 
 # all secrets for that script or bucket.  encpass.sh sets up a directory 
 # (.encpass) under the user's home directory where keys and secrets will be 
 # stored.

In a class component context...

If the changeHandler method is a normal function:

handleChange(e){
    this.setState({[e.target.name]:[e.target.value]});
}

it can be used such as this...onChange={(e)=>this.handleChange(e)}

<input type="text" name="any" value={this.state.any} onChange={(e)=>this.handleChange(e)}></input>

If the changeHandler method is an arrow function:

handle = (e) =>{
        this.setState({[e.target.name]:[e.target.value]});
    }

it can be used like this... onChange={this.handle}

 <input type="text" name="any2" value={this.state.any2} onChange={this.handle} ></input>

And this solved my "Can't type in React input text field" problem.

I could suggest just install Terminal-ide on you device which available in play market. Its free, does not require root and provide convenient *nix environment like cp, find, du, mc and many other utilities which installed in binary form by one button tap.

Apple has changed the interface.

The general solution to interpreting a char as a string is string("HELLO"[1]).

Rich's solution also works, of course.

Are you using this compare in a very-frequently-executed path of a highly-performance-sensitive application? Alternatively, are you running this on strings which are megabytes in size? If not, then you shouldn't worry about the performance and just use the .lower() method.

The following code demonstrates that doing a case-insensitive compare by calling .lower() on two strings which are each almost a megabyte in size takes about 0.009 seconds on my 1.8GHz desktop computer:

from timeit import Timer

s1 = "1234567890" * 100000 + "a"
s2 = "1234567890" * 100000 + "B"

code = "s1.lower() < s2.lower()"
time = Timer(code, "from __main__ import s1, s2").timeit(1000)
print time / 1000   # 0.00920499992371 on my machine

If indeed this is an extremely significant, performance-critical section of code, then I recommend writing a function in C and calling it from your Python code, since that will allow you to do a truly efficient case-insensitive search. Details on writing C extension modules can be found here: https://docs.python.org/extending/extending.html

EDIT: This answer is correct for version 0.2.10. As @Alexander Vasilyev pointed out it doesn't work in version 0.2.14.

Another reason to use $state.params is when you need to extract query parameters like this:

$stateProvider.state('a', {
  url: 'path/:id/:anotherParam/?yetAnotherParam',
  controller: 'ACtrl',
});

module.controller('ACtrl', function($stateParams, $state) {
  $state.params; // has id, anotherParam, and yetAnotherParam
  $stateParams;  // has id and anotherParam
}

Here is an example of a parent List react component and whos props contain a react element. In this case, just a single Link react component is passed in (as seen in the dom render).

class Link extends React.Component {
  constructor(props){
    super(props);
  }
  render(){
    return (
      <div>
        <p>{this.props.name}</p>
      </div>
     );
  }
}
class List extends React.Component {
  render(){
   return(
    <div>
       {this.props.element}
       {this.props.element}
    </div>
   );
  }
}

ReactDOM.render(
  <List element = {<Link name = "working"/>}/>,
  document.getElementById('root')
);

The following steps are to reset the password for a user in case you forgot, this would also solve your mentioned error.

First, stop your MySQL:

sudo /etc/init.d/mysql stop

Now start up MySQL in safe mode and skip the privileges table:

sudo mysqld_safe --skip-grant-tables &

Login with root:

mysql -uroot

And assign the DB that needs to be used:

use mysql;

Now all you have to do is reset your root password of the MySQL user and restart the MySQL service:

update user set password=PASSWORD("YOURPASSWORDHERE") where User='root';

flush privileges;

quit and restart MySQL:

quit

sudo /etc/init.d/mysql stop sudo /etc/init.d/mysql start Now your root password should be working with the one you just set, check it with:

mysql -u root -p

Yes, bool. It's not exactly the same -- '0' is True, but None, False, [], 0, 0.0, and "" are all False.

bool is used implicitly when you evaluate an object in a condition like an if or while statement, conditional expression, or with a boolean operator.

If you wanted to handle strings containing numbers as PHP does, you could do something like:

def empty(value):
    try:
        value = float(value)
    except ValueError:
        pass
    return bool(value)

Have a look at here this link and their roadmap. They have RO|C on the way, and that can connect to their web services, which probably includes SOAP (I use the VCL version which definitely includes it).

building on @ltamar's answer:
Use summary and munge the output into something useful!

library(tidyr)
library(dplyr)

df %>% 
  summary %>% 
  data.frame %>%
  select(-Var1) %>%
  separate(data=.,col=Freq,into = c('metric','value'),sep = ':') %>%
  rename(column_name=Var2) %>%
  mutate(value=as.numeric(value),
         metric = trimws(metric,'both') 
  ) %>%  
  filter(!is.na(value)) -> metrics

It's not pretty and it is certainly not fast but it gets the job done!

I finally found the problem. The error was not the good one.

Apparently, Ole DB source have a bug that might make it crash and throw that error. I replaced the OLE DB destination with a OLE DB Command with the insert statement in it and it fixed it.

The link the got me there: http://social.msdn.microsoft.com/Forums/en-US/sqlintegrationservices/thread/fab0e3bf-4adf-4f17-b9f6-7b7f9db6523c/

Strange Bug, Hope it will help other people.

When you want to make your php value storable, you have to turn it to be a string value, that is what serialize() does. And unserialize() does the reverse thing.

String text = "In early March, the city of Topeka, Kansas," + "<br>" +
              "temporarily changed its name to Google..." + "<br>" + "<br>" +
              "...in an attempt to capture a spot" + "<br>" +
              "in Google's new broadband/fiber-optics project." + "<br>" + "<br>" +"<br>" +
              "source: http://en.wikipedia.org/wiki/Google_server#Oil_Tanker_Data_Center";
JLabel label = new JLabel("<html><div style='text-align: center;'>" + text + "</div></html>");

There is no difference in working in both the concepts of assignment to unique_ptr.

int* intPtr = new int(3);
unique_ptr<int> uptr (intPtr);

is similar to

unique_ptr<int> uptr (new int(3));

Here unique_ptr automatically deletes the space occupied by uptr.

how pointers, declared in this way will be different from the pointers declared in a "normal" way.

If you create an integer in heap space (using new keyword or malloc), then you will have to clear that memory on your own (using delete or free respectively).

In the below code,

int* heapInt = new int(5);//initialize int in heap memory
.
.//use heapInt
.
delete heapInt;

Here, you will have to delete heapInt, when it is done using. If it is not deleted, then memory leakage occurs.

In order to avoid such memory leaks unique_ptr is used, where unique_ptr automatically deletes the space occupied by heapInt when it goes out of scope. So, you need not do delete or free for unique_ptr.

There are some online services for obfuscate php to hide the code from others. This is one Right Coder's Free Obfuscator Online

@Glavic is right. "Nothing is bulletproof". You can encode your source code and hide from bigger programmers, not from experts.

location_of_line = 0
with open(filename, 'r') as file_you_want_to_read:
     #readlines in file and put in a list
     contents = file_you_want_to_read.readlines()

     #find location of what line you want to insert after
     for index, line in enumerate(contents):
            if line.startswith('whatever you are looking for')
                   location_of_line = index

#now you have a list of every line in that file
context.insert(location_of_line, "whatever you want to append to middle of file")
with open(filename, 'w') as file_to_write_to:
        file_to_write_to.writelines(contents)

That is how I ended up getting whatever data I want to insert to the middle of the file.

this is just pseudo code, as I was having a hard time finding clear understanding of what is going on.

essentially you read in the file to its entirety and add it into a list, then you insert your lines that you want to that list, and then re-write to the same file.

i am sure there are better ways to do this, may not be efficient, but it makes more sense to me at least, I hope it makes sense to someone else.

The Answer of "Is a GUID is 100% unique?" is simply "No" .

• If You want 100% uniqueness of GUID then do following.

  1. generate GUID
  2. check if that GUID is Exist in your table column where you are looking for uniquensess
  3. if exist then goto step 1 else step 4
  4. use this GUID as unique.

I was also getting this issue also however none of the above worked for me as I was using a custom binding (for BinaryXML) after an long time digging I found the answer here :-

Sending large XML from Silverlight to WCF

As am using a customBinding, the maxReceivedMessageSize has to be set on the httpTransport element under the binding element in the web.config:

<httpsTransport maxReceivedMessageSize="4194304" /> 

With lodash:

const items = [
    { key: 'foo', value: 'bar' },
    { key: 'hello', value: 'world' }
];

const map = _.fromPairs(items.map(item => [item.key, item.val]));

// OR: if you want to index the whole item by key:
// const map = _.fromPairs(items.map(item => [item.key, item]));

The lodash fromPairs function reminds me about zip function in Python

Link to lodash

Give this a try

$indo=$_GET['id'];
$result = mysql_query("SELECT * FROM student WHERE IDNO='$indo'");

I think this works..

I struggled with this, too. Here's what I found. Expanding on Adam's answer, here's a bit more detail, including how to encode VP9 with alpha in a Webm container.

First, Here's a CodePen playground you can play with, feel free to use my videos for testing.

        <video width="600" height="100%" autoplay loop muted playsinline>
        <source src="https://rotato.netlify.app/alpha-demo/movie-hevc.mov" type='video/mp4'; codecs="hvc1">
        <source src="https://rotato.netlify.app/alpha-demo/movie-webm.webm" type="video/webm">
        </video>

And here's a full demo page using z-index to layer the transparent video on top and below certain elements. (You can clone the Webflow template)

So, we'll need a Webm movie for Chrome, and an HEVC with Alpha (supported by Safari on all platforms since 2019)

Which browsers are supported?

For Chrome, I've tested successfully on version 30 from 2013. (Caniuse webm doesn't seem to say which webm codec is supported, so I had to try my way). Earlier versions of chrome seem to render a black area.

For Safari, it's simpler: Catalina (2019) or iOS 11 (2019)

Encoding

Depending on which editing app you're using, I recommend exporting the HEVC with Alpha directly.

But many apps don't support the Webm format, especially on Mac, since it's not a part of AVFoundation.

I recommend exporting an intermediate format like ProRes4444 with an alpha channel to not lose too much quality at this step. Once you have that file, making your webm is as simple as

ffmpeg -i "your-movie-in-prores.mov" -c:v libvpx-vp9 movie-webm.webm

See more approaches in this blog post.

You can get more info about the error with the method $mail->ErrorInfo. For example:

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

This is an alternative to the exception model that you need to active with new PHPMailer(true). But if can use exception model, use it as @Phil Rykoff answer.

This comes from the main page of PHPMailer on github https://github.com/PHPMailer/PHPMailer.

These are the two options I managed to build, not having the luxury of working with var type, nor with additional variables on the line:

string f = "aS.".Substring(0, "aS.".IndexOf("S"));
Console.WriteLine(f);

string s = "aS.".Split("S".ToCharArray(),StringSplitOptions.RemoveEmptyEntries)[0];
Console.WriteLine(s);

This is what it gets:

listOfNames="db_one db_two db_three"
for databaseName in $listOfNames
do
  echo $databaseName
done

or just

for databaseName in db_one db_two db_three
do
  echo $databaseName
done

This would print the files in those directories line by line.

array=(ww/* ee/* qq/*)
printf "%s\n" "${array[@]}"

If you want an efficient way with milliseconds:

var daysOfYear = [];
for (var d = begin; d <= end; d = d + 86400000) {
    daysOfYear.push(new Date(d));
}

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

B+Trees are much easier and higher performing to do a full scan, as in look at every piece of data that the tree indexes, since the terminal nodes form a linked list. To do a full scan with a B-Tree you need to do a full tree traversal to find all the data.

B-Trees on the other hand can be faster when you do a seek (looking for a specific piece of data by key) especially when the tree resides in RAM or other non-block storage. Since you can elevate commonly used nodes in the tree there are less comparisons required to get to the data.

IDP Initiated SSO

From PingFederate documentation :- https://docs.pingidentity.com/bundle/pf_sm_supportedStandards_pf82/page/task/idpInitiatedSsoPOST.html

In this scenario, a user is logged on to the IdP and attempts to access a resource on a remote SP server. The SAML assertion is transported to the SP via HTTP POST.

Processing Steps:

1. A user has logged on to the IdP.
2. The user requests access to a protected SP resource. The user is not logged on to the SP site.
3. Optionally, the IdP retrieves attributes from the user data store.
4. The IdP’s SSO service returns an HTML form to the browser with a SAML response containing the authentication assertion and any additional attributes. The browser automatically posts the HTML form back to the SP.

SP Initiated SSO

From PingFederate documentation:- http://documentation.pingidentity.com/display/PF610/SP-Initiated+SSO--POST-POST

In this scenario a user attempts to access a protected resource directly on an SP Web site without being logged on. The user does not have an account on the SP site, but does have a federated account managed by a third-party IdP. The SP sends an authentication request to the IdP. Both the request and the returned SAML assertion are sent through the user’s browser via HTTP POST.

Processing Steps:

1. The user requests access to a protected SP resource. The request is redirected to the federation server to handle authentication.
2. The federation server sends an HTML form back to the browser with a SAML request for authentication from the IdP. The HTML form is automatically posted to the IdP’s SSO service.
3. If the user is not already logged on to the IdP site or if re-authentication is required, the IdP asks for credentials (e.g., ID and password) and the user logs on.

4. Additional information about the user may be retrieved from the user data store for inclusion in the SAML response. (These attributes are predetermined as part of the federation agreement between the IdP and the SP)

5. The IdP’s SSO service returns an HTML form to the browser with a SAML response containing the authentication assertion and any additional attributes. The browser automatically posts the HTML form back to the SP. NOTE: SAML specifications require that POST responses be digitally signed.

6. (Not shown) If the signature and assertion are valid, the SP establishes a session for the user and redirects the browser to the target resource.

See populate a database in the PostgreSQL manual, depesz's excellent-as-usual article on the topic, and this SO question.

(Note that this answer is about bulk-loading data into an existing DB or to create a new one. If you're interested DB restore performance with pg_restore or psql execution of pg_dump output, much of this doesn't apply since pg_dump and pg_restore already do things like creating triggers and indexes after it finishes a schema+data restore).

There's lots to be done. The ideal solution would be to import into an UNLOGGED table without indexes, then change it to logged and add the indexes. Unfortunately in PostgreSQL 9.4 there's no support for changing tables from UNLOGGED to logged. 9.5 adds ALTER TABLE ... SET LOGGED to permit you to do this.

If you can take your database offline for the bulk import, use pg_bulkload.

Otherwise:

• Disable any triggers on the table

• Drop indexes before starting the import, re-create them afterwards. (It takes much less time to build an index in one pass than it does to add the same data to it progressively, and the resulting index is much more compact).

• If doing the import within a single transaction, it's safe to drop foreign key constraints, do the import, and re-create the constraints before committing. Do not do this if the import is split across multiple transactions as you might introduce invalid data.

• If possible, use COPY instead of INSERTs

• If you can't use COPY consider using multi-valued INSERTs if practical. You seem to be doing this already. Don't try to list too many values in a single VALUES though; those values have to fit in memory a couple of times over, so keep it to a few hundred per statement.

• Batch your inserts into explicit transactions, doing hundreds of thousands or millions of inserts per transaction. There's no practical limit AFAIK, but batching will let you recover from an error by marking the start of each batch in your input data. Again, you seem to be doing this already.

• Use synchronous_commit=off and a huge commit_delay to reduce fsync() costs. This won't help much if you've batched your work into big transactions, though.

• INSERT or COPY in parallel from several connections. How many depends on your hardware's disk subsystem; as a rule of thumb, you want one connection per physical hard drive if using direct attached storage.

• Set a high checkpoint_segments value and enable log_checkpoints. Look at the PostgreSQL logs and make sure it's not complaining about checkpoints occurring too frequently.

• If and only if you don't mind losing your entire PostgreSQL cluster (your database and any others on the same cluster) to catastrophic corruption if the system crashes during the import, you can stop Pg, set fsync=off, start Pg, do your import, then (vitally) stop Pg and set fsync=on again. See WAL configuration. Do not do this if there is already any data you care about in any database on your PostgreSQL install. If you set fsync=off you can also set full_page_writes=off; again, just remember to turn it back on after your import to prevent database corruption and data loss. See non-durable settings in the Pg manual.

You should also look at tuning your system:

• Use good quality SSDs for storage as much as possible. Good SSDs with reliable, power-protected write-back caches make commit rates incredibly faster. They're less beneficial when you follow the advice above - which reduces disk flushes / number of fsync()s - but can still be a big help. Do not use cheap SSDs without proper power-failure protection unless you don't care about keeping your data.

• If you're using RAID 5 or RAID 6 for direct attached storage, stop now. Back your data up, restructure your RAID array to RAID 10, and try again. RAID 5/6 are hopeless for bulk write performance - though a good RAID controller with a big cache can help.

• If you have the option of using a hardware RAID controller with a big battery-backed write-back cache this can really improve write performance for workloads with lots of commits. It doesn't help as much if you're using async commit with a commit_delay or if you're doing fewer big transactions during bulk loading.

• If possible, store WAL (pg_xlog) on a separate disk / disk array. There's little point in using a separate filesystem on the same disk. People often choose to use a RAID1 pair for WAL. Again, this has more effect on systems with high commit rates, and it has little effect if you're using an unlogged table as the data load target.

You need to make use of Label Callback. A common example to round data values, the following example rounds the data to two decimal places.

var chart = new Chart(ctx, {
    type: 'line',
    data: data,
    options: {
        tooltips: {
            callbacks: {
                label: function(tooltipItem, data) {
                    var label = data.datasets[tooltipItem.datasetIndex].label || '';

                    if (label) {
                        label += ': ';
                    }
                    label += Math.round(tooltipItem.yLabel * 100) / 100;
                    return label;
                }
            }
        }
    }
});

Now let me write the scenario where I used the label callback functionality.

Let's start with logging the arguments of Label Callback function, you will see structure similar to this here datasets, array comprises of different lines you want to plot in the chart. In my case it's 4, that's why length of datasets array is 4.

In my case, I had to perform some calculations on each dataset and have to identify the correct line, every-time I hover upon a line in a chart.

To differentiate different lines and manipulate the data of hovered tooltip based on the data of other lines I had to write this logic.

  callbacks: {
    label: function (tooltipItem, data) {
      console.log('data', data);
      console.log('tooltipItem', tooltipItem);
      let updatedToolTip: number;
      if (tooltipItem.datasetIndex == 0) {
        updatedToolTip = tooltipItem.yLabel;
      }
      if (tooltipItem.datasetIndex == 1) {
        updatedToolTip = tooltipItem.yLabel - data.datasets[0].data[tooltipItem.index];
      }
      if (tooltipItem.datasetIndex == 2) {
        updatedToolTip = tooltipItem.yLabel - data.datasets[1].data[tooltipItem.index];
      }
      if (tooltipItem.datasetIndex == 3) {
        updatedToolTip = tooltipItem.yLabel - data.datasets[2].data[tooltipItem.index]
      }
      return updatedToolTip;
    }
  } 

Above mentioned scenario will come handy, when you have to plot different lines in line-chart and manipulate tooltip of the hovered point of a line, based on the data of other point belonging to different line in the chart at the same index.

This benchmark shows that regular concatenation is faster when combining 3 or fewer strings.

StringBuilder can make a very significant improvement in memory usage, especially in your case of adding 500 strings together.

Consider the following example:

string buffer = "The numbers are: ";
for( int i = 0; i < 5; i++)
{
    buffer += i.ToString();
}
return buffer;

What happens in memory? The following strings are created:

1 - "The numbers are: "
2 - "0"
3 - "The numbers are: 0"
4 - "1"
5 - "The numbers are: 01"
6 - "2"
7 - "The numbers are: 012"
8 - "3"
9 - "The numbers are: 0123"
10 - "4"
11 - "The numbers are: 01234"
12 - "5"
13 - "The numbers are: 012345"

By adding those five numbers to the end of the string we created 13 string objects! And 12 of them were useless! Wow!

StringBuilder fixes this problem. It is not a "mutable string" as we often hear (all strings in .NET are immutable). It works by keeping an internal buffer, an array of char. Calling Append() or AppendLine() adds the string to the empty space at the end of the char array; if the array is too small, it creates a new, larger array, and copies the buffer there. So in the example above, StringBuilder might only need a single array to contain all 5 additions to the string-- depending on the size of its buffer. You can tell StringBuilder how big its buffer should be in the constructor.

You can take the SelectedItem and cast it back to your class and access its properties.

 MessageBox.Show(((ComboboxItem)ComboBox_Countries_In_Silvers.SelectedItem).Value);

Edit You can try using DataTextField and DataValueField, I used it with DataSource.

ComboBox_Servers.DataTextField = "Text";
ComboBox_Servers.DataValueField = "Value";

I would suggest to read up a bit on the syntax. See here.

if (dsnt<0.05) {
  wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE) 
} else if (dst<0.05) {
    wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else 
  t.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)

Apparently, no.

Here's the options:

• Use Type.IsSubclassOf
• Use Type.IsAssignableFrom
• is and as

Type.IsSubclassOf

As you've already found out, this will not work if the two types are the same, here's a sample LINQPad program that demonstrates:

void Main()
{
    typeof(Derived).IsSubclassOf(typeof(Base)).Dump();
    typeof(Base).IsSubclassOf(typeof(Base)).Dump();
}

public class Base { }
public class Derived : Base { }

Output:

True
False

Which indicates that Derived is a subclass of Base, but that Baseis (obviously) not a subclass of itself.

Type.IsAssignableFrom

Now, this will answer your particular question, but it will also give you false positives. As Eric Lippert has pointed out in the comments, while the method will indeed return True for the two above questions, it will also return True for these, which you probably don't want:

void Main()
{
    typeof(Base).IsAssignableFrom(typeof(Derived)).Dump();
    typeof(Base).IsAssignableFrom(typeof(Base)).Dump();
    typeof(int[]).IsAssignableFrom(typeof(uint[])).Dump();
}

public class Base { }
public class Derived : Base { }

Here you get the following output:

True
True
True

The last True there would indicate, if the method only answered the question asked, that uint[] inherits from int[] or that they're the same type, which clearly is not the case.

So IsAssignableFrom is not entirely correct either.

is and as

The "problem" with is and as in the context of your question is that they will require you to operate on the objects and write one of the types directly in code, and not work with Type objects.

In other words, this won't compile:

SubClass is BaseClass
^--+---^
   |
   +-- need object reference here

nor will this:

typeof(SubClass) is typeof(BaseClass)
                    ^-------+-------^
                            |
                            +-- need type name here, not Type object

nor will this:

typeof(SubClass) is BaseClass
^------+-------^
       |
       +-- this returns a Type object, And "System.Type" does not
           inherit from BaseClass

Conclusion

While the above methods might fit your needs, the only correct answer to your question (as I see it) is that you will need an extra check:

typeof(Derived).IsSubclassOf(typeof(Base)) || typeof(Derived) == typeof(Base);

which of course makes more sense in a method:

public bool IsSameOrSubclass(Type potentialBase, Type potentialDescendant)
{
    return potentialDescendant.IsSubclassOf(potentialBase)
           || potentialDescendant == potentialBase;
}

Simple way to detect scroll up/down on android listview

@Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount){
  if(prevVisibleItem != firstVisibleItem){
    if(prevVisibleItem < firstVisibleItem)
      //ScrollDown
    else
      //ScrollUp

  prevVisibleItem = firstVisibleItem;
}

dont forget

yourListView.setOnScrollListener(yourScrollListener);

Use Linq-XML,

XDocument doc = XDocument.Load(file);

var result = from ele in doc.Descendants("sog")
              select new
              {
                 field1 = (string)ele.Element("field1")
              };
 foreach (var t in result)
  {
      HttpContext.Current.Response.Write(t.field1);
  }

OR : Get the node list of <sog> tag.

 XmlDocument xmlDoc = new XmlDocument();
 xmlDoc.Load(myXML);
 XmlNodeList parentNode = xmlDoc.GetElementsByTagName("sog");
 foreach (XmlNode childrenNode in parentNode)
  {
    HttpContext.Current.Response.Write(childrenNode.SelectSingleNode("field1").InnerText);
   }

The alternate way, that doesn't require RPMs. You need to be root.

1. Dependencies

   Install the following packages:

   apt-get install python-dev build-essential libaio1
   

2. Download Instant Client for Linux x86-64

   Download the following files from Oracle's download site:

   

3. Extract the zip files

   Unzip the downloaded zip files to some directory, I'm using:

   /opt/ora/
   

4. Add environment variables

   Create a file in /etc/profile.d/oracle.sh that includes

   export ORACLE_HOME=/opt/ora/instantclient_11_2
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME
   

   Create a file in /etc/ld.so.conf.d/oracle.conf that includes

   /opt/ora/instantclient_11_2
   

   Execute the following command

   sudo ldconfig
   

   Note: you may need to reboot to apply settings

5. Create a symlink

   cd $ORACLE_HOME 
   ln -s libclntsh.so.11.1 libclntsh.so
   

6. Install cx_Oracle python package

   • You may install using pip

     pip install cx_Oracle
     

   • Or install manually

     Download the cx_Oracle source zip that corresponds with your Python and Oracle version. Then expand the archive, and run from the extracted directory:

     python setup.py build 
     python setup.py install
     

Most answers given here have a huge disadvantage: if the string you are trying to convert isn't trusted then you will end up with a Cross-Site Scripting (XSS) vulnerability. For the function in the accepted answer, consider the following:

htmlDecode("<img src='dummy' onerror='alert(/xss/)'>");

The string here contains an unescaped HTML tag, so instead of decoding anything the htmlDecode function will actually run JavaScript code specified inside the string.

This can be avoided by using DOMParser which is supported in all modern browsers:

function htmlDecode(input) {_x000D_
  var doc = new DOMParser().parseFromString(input, "text/html");_x000D_
  return doc.documentElement.textContent;_x000D_
}_x000D_
_x000D_
console.log(  htmlDecode("<img src='myimage.jpg'>")  )    _x000D_
// "<img src='myimage.jpg'>"_x000D_
_x000D_
console.log(  htmlDecode("<img src='dummy' onerror='alert(/xss/)'>")  )  _x000D_
// ""

This function is guaranteed to not run any JavaScript code as a side-effect. Any HTML tags will be ignored, only text content will be returned.

Compatibility note: Parsing HTML with DOMParser requires at least Chrome 30, Firefox 12, Opera 17, Internet Explorer 10, Safari 7.1 or Microsoft Edge. So all browsers without support are way past their EOL and as of 2017 the only ones that can still be seen in the wild occasionally are older Internet Explorer and Safari versions (usually these still aren't numerous enough to bother).

from is a keyword in SQL. You may not used it as a column name without quoting it. In MySQL, things like column names are quoted using backticks, i.e. `from`.

Personally, I wouldn't bother; I'd just rename the column.

PS. as pointed out in the comments, to is another SQL keyword so it needs to be quoted, too. Conveniently, the folks at drupal.org maintain a list of reserved words in SQL.

Well, here's an example for overloaded constructors.

public class Employee
{
   private String name;
   private int age;

   public Employee()
   {
      System.out.println("We are inside Employee() constructor");
   }

   public Employee(String name)
   {
      System.out.println("We are inside Employee(String name) constructor");
      this.name = name;
   }

   public Employee(String name, int age)
   {
      System.out.println("We are inside Employee(String name, int age) constructor");
      this.name = name;
      this.age = age;
   }

   public Employee(int age)
   {
      System.out.println("We are inside Employee(int age) constructor");
      this.age = age; 
   }

   public String getName()
   {
      return name;
   }

   public void setName(String name)
   {
      this.name = name;
   }

   public int getAge()
   {
      return age;
   }

   public void setAge(int age)
   {
      this.age = age;
   }
}

In the above example you can see overloaded constructors. Name of the constructors is same but each constructors has different parameters.

Here are some resources which throw more light on constructor overloading in java,

Constructors.

Constructor explanation.

You could try using below command-

pip install opencv-contrib-python

It will basically download the compatible version. If this command fails, you could upgrade you pip using below command-

python -m pip install –upgrade pip

If you need a pictorial guide, head over to Simple Steps to Install OpenCV in Windows

You can also try installing OpenCV from prebuilt binaries from the official OpenCV site.

Both array_push and the method you described will work.

$cart = array();
$cart[] = 13;
$cart[] = 14;
// etc

//Above is correct. but below one is for further understanding
$cart = array();
for($i=0;$i<=5;$i++){
    $cart[] = $i;  
}
echo "<pre>";
print_r($cart);
echo "</pre>";

Is the same as:

<?php
$cart = array();
array_push($cart, 13);
array_push($cart, 14);

// Or 
$cart = array();
array_push($cart, 13, 14);
?>

# to strip `,` and `.` from a string ->

>>> 'a,b,c.'.translate(None, ',.')
'abc'

You should use the built-in translate method for strings.

Type help('abc'.translate) at Python shell for more info.

I have the same need for downloading images using requests. I first tried the answer of Martijn Pieters, and it works well. But when I did a profile on this simple function, I found that it uses so many function calls compared to urllib and urllib2.

I then tried the way recommended by the author of requests module:

import requests
from PIL import Image
# python2.x, use this instead  
# from StringIO import StringIO
# for python3.x,
from io import StringIO

r = requests.get('https://example.com/image.jpg')
i = Image.open(StringIO(r.content))

This much more reduced the number of function calls, thus speeded up my application. Here is the code of my profiler and the result.

#!/usr/bin/python
import requests
from StringIO import StringIO
from PIL import Image
import profile

def testRequest():
    image_name = 'test1.jpg'
    url = 'http://example.com/image.jpg'

    r = requests.get(url, stream=True)
    with open(image_name, 'wb') as f:
        for chunk in r.iter_content():
            f.write(chunk)

def testRequest2():
    image_name = 'test2.jpg'
    url = 'http://example.com/image.jpg'

    r = requests.get(url)

    i = Image.open(StringIO(r.content))
    i.save(image_name)

if __name__ == '__main__':
    profile.run('testUrllib()')
    profile.run('testUrllib2()')
    profile.run('testRequest()')

The result for testRequest:

343080 function calls (343068 primitive calls) in 2.580 seconds

And the result for testRequest2:

3129 function calls (3105 primitive calls) in 0.024 seconds

If you dont have SDK or you are setting up 3rd party app here is another way:

1. Copy the .APK file to your device.
2. Use file manager to locate the file.
3. Then click on it.
4. Android App installer should be one of the options in pop-up.
5. Select it and it installs.

For anyone here that wants a super-simple answer: just set the level you want displayed. At the top of all my scripts I just put:

import logging
logging.basicConfig(level = logging.INFO)

Then to display anything at or above that level:

logging.info("Hi you just set your fleeb to level plumbus")

It is a hierarchical set of five levels so that logs will display at the level you set, or higher. So if you want to display an error you could use logging.error("The plumbus is broken").

The levels, in increasing order of severity, are DEBUG, INFO, WARNING, ERROR, and CRITICAL. The default setting is WARNING.

This can be achieved through LINQ with grouping, here a list of items pointed as a data source to the actual grid view. Sample pseudo code which could help coding the actual.

var tabelDetails =(from li in dc.My_table
    join m in dc.Table_One on li.ID equals m.ID
    join c in dc.Table_two on li.OtherID equals c.ID
    where //Condition
group new { m, li, c } by new
{
    m.ID,
    m.Name
} into g
select new
{
    g.Key.ID,
    Name = g.Key.FullName,
    sponsorBonus= g.Where(s => s.c.Name == "sponsorBonus").Count(),
    pairingBonus = g.Where(s => s.c.Name == "pairingBonus").Count(),
    staticBonus = g.Where(s => s.c.Name == "staticBonus").Count(),   
    leftBonus = g.Where(s => s.c.Name == "leftBonus").Count(),  
    rightBonus = g.Where(s => s.c.Name == "rightBonus").Count(),  
    Total = g.Count()  //Row wise Total
}).OrderBy(t => t.Name).ToList();

tabelDetails.Insert(tabelDetails.Count(), new  //This data will be the last row of the grid
{
    Name = "Total",  //Column wise total
    sponsorBonus = tabelDetails.Sum(s => s.sponsorBonus),
    pairingBonus = tabelDetails.Sum(s => s.pairingBonus),
    staticBonus = tabelDetails.Sum(s => s.staticBonus),
    leftBonus = tabelDetails.Sum(s => s.leftBonus),
    rightBonus = tabelDetails.Sum(s => s.rightBonus ),
    Total = tabelDetails.Sum(s => s.Total)
});

Python has a "not" operator, right? Is it not just "not"? As in,

Use the floating number to subtract the floored value to get its fractional part:

double fractional = some_double - floor(some_double);

This prevents the typecasting to an integer, which may cause overflow if the floating number is very large that an integer value could not even contain it.

Also for negative values, this code gives you the positive fractional part of the floating number since floor() computes the largest integer value not greater than the input value.

It is worth noting that sizeof doesn't help when dealing with an array value that has decayed to a pointer: even though it points to the start of an array, to the compiler it is the same as a pointer to a single element of that array. A pointer does not "remember" anything else about the array that was used to initialize it.

int a[10];
int* p = a;

assert(sizeof(a) / sizeof(a[0]) == 10);
assert(sizeof(p) == sizeof(int*));
assert(sizeof(*p) == sizeof(int));

From man diff, you can use -y to do side-by-side.

-y, --side-by-side

Hence, say:

$ cat a                $ cat b
hello                  hello
my name                my name
is me                  is you

Let's compare them:

$ diff -y a b
hello                                                           hello

In Java Class:

    public class EnumTest{
    //Other property link
    private String name;
    ....

        public enum Status {
                ACTIVE,NEWLINK, BROADCASTED, PENDING, CLICKED, VERIFIED, AWARDED, INACTIVE, EXPIRED, DELETED_BY_ADMIN;
            }

        private Status statusobj ;

    //Getter and Setters
}

So now POJO and enum obj is created. Now EnumTest you will set in session object using in the servlet or controller class session.setAttribute("enumTest", EnumTest );

In JSP Page

<c:if test="${enumTest.statusobj == 'ACTIVE'}">

//TRUE??? THEN PROCESS SOME LOGIC

I had the same problem for a long time. I solved it by running these two commands, first is to install second is to activate the env:

python3 -m pip install virtualenv
python3 -m virtualenv yourenvname

Note that I'm using python3, you can change it to just python if python3 fails. Thanks.

To resize the image proportionally using CSS:

img.resize {
    width:540px; /* you can use % */
    height: auto;
}

Thats how it works stored procedures run in order, you don't need begin just something like

exec dbo.sp1
exec dbo.sp2

Some other options, just for reference

-10.days.ago
# Available in Rails 4
DateTime.now.days_ago(-10)

Just list out all options I know:

[1] Time.now + 10.days
[2] 10.days.from_now
[3] -10.days.ago
[4] DateTime.now.days_ago(-10)
[5] Date.today + 10

So now, what is the difference between them if we care about the timezone:

• [1, 4] With system timezone
• [2, 3] With config timezone of your Rails app
• [5] Date only no time included in result

i do it with os.system temp file:

import tempfile,os
def readcmd(cmd):
    ftmp = tempfile.NamedTemporaryFile(suffix='.out', prefix='tmp', delete=False)
    fpath = ftmp.name
    if os.name=="nt":
        fpath = fpath.replace("/","\\") # forwin
    ftmp.close()
    os.system(cmd + " > " + fpath)
    data = ""
    with open(fpath, 'r') as file:
        data = file.read()
        file.close()
    os.remove(fpath)
    return data

With Swift 3, you can choose one of the following ways to solve your problem.

1. Using sorted(by:?) with a Movie class that does not conform to Comparable protocol

If your Movie class does not conform to Comparable protocol, you must specify in your closure the property on which you wish to use Array's sorted(by:?) method.

Movie class declaration:

import Foundation

class Movie: CustomStringConvertible {

    let name: String
    var date: Date
    var description: String { return name }

    init(name: String, date: Date = Date()) {
        self.name = name
        self.date = date
    }

}

Usage:

let avatarMovie = Movie(name: "Avatar")
let titanicMovie = Movie(name: "Titanic")
let piranhaMovie = Movie(name: "Piranha II: The Spawning")

let movies = [avatarMovie, titanicMovie, piranhaMovie]
let sortedMovies = movies.sorted(by: { $0.name < $1.name })
// let sortedMovies = movies.sorted { $0.name < $1.name } // also works

print(sortedMovies)

/*
prints: [Avatar, Piranha II: The Spawning, Titanic]
*/

2. Using sorted(by:?) with a Movie class that conforms to Comparable protocol

However, by making your Movie class conform to Comparable protocol, you can have a much concise code when you want to use Array's sorted(by:?) method.

Movie class declaration:

import Foundation

class Movie: CustomStringConvertible, Comparable {

    let name: String
    var date: Date
    var description: String { return name }

    init(name: String, date: Date = Date()) {
        self.name = name
        self.date = date
    }

    static func ==(lhs: Movie, rhs: Movie) -> Bool {
        return lhs.name == rhs.name
    }

    static func <(lhs: Movie, rhs: Movie) -> Bool {
        return lhs.name < rhs.name
    }

}

Usage:

let avatarMovie = Movie(name: "Avatar")
let titanicMovie = Movie(name: "Titanic")
let piranhaMovie = Movie(name: "Piranha II: The Spawning")

let movies = [avatarMovie, titanicMovie, piranhaMovie]
let sortedMovies = movies.sorted(by: { $0 < $1 })
// let sortedMovies = movies.sorted { $0 < $1 } // also works
// let sortedMovies = movies.sorted(by: <) // also works

print(sortedMovies)

/*
 prints: [Avatar, Piranha II: The Spawning, Titanic]
 */

3. Using sorted() with a Movie class that conforms to Comparable protocol

By making your Movie class conform to Comparable protocol, you can use Array's sorted() method as an alternative to sorted(by:?).

Movie class declaration:

import Foundation

class Movie: CustomStringConvertible, Comparable {

    let name: String
    var date: Date
    var description: String { return name }

    init(name: String, date: Date = Date()) {
        self.name = name
        self.date = date
    }

    static func ==(lhs: Movie, rhs: Movie) -> Bool {
        return lhs.name == rhs.name
    }

    static func <(lhs: Movie, rhs: Movie) -> Bool {
        return lhs.name < rhs.name
    }

}

Usage:

let avatarMovie = Movie(name: "Avatar")
let titanicMovie = Movie(name: "Titanic")
let piranhaMovie = Movie(name: "Piranha II: The Spawning")

let movies = [avatarMovie, titanicMovie, piranhaMovie]
let sortedMovies = movies.sorted()

print(sortedMovies)

/*
 prints: [Avatar, Piranha II: The Spawning, Titanic]
 */

webView.setBackgroundColor(0x00000000);
webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);

this will definitely work.. set background in XML with Editbackground. Now that background will be shown

In classic sh, you have to do something like:

s=test1
s="${s}test2"

(there are lots of variations on that theme, like s="$s""test2")

In bash, you can use +=:

s=test1
s+=test2

Are you using virtualenv?

if so, you need to notify PyCharm for every change in the location of the the desired python.exe (merely ./activate is not enough for PyCharm)

Make sure Pycharm points to the correct interpetor and packages: File -> Settings -> Project -> Project Interpreter. Click the gear and choose python.exe under virtualenv's Scripts folder

Using 'now()' as default value automatically generates time-stamp.

Here is some code that might help you out. Strings can be treated as an array of characters

string numbers = "12345";
int[] intArray = new int[numbers.Length];
for (int i=0; i < numbers.Length; i++)
{
   intArray[i] = int.Parse(numbers[i]);
}

Drag the variable from Variables pane to Watch pane and voila!

@JoinColumn(name="reference_column_name") annotation can be used above that property or field of class that is being referenced from some other entity.

The reason is that for deleting an object, Hibernate requires that the object is in persistent state. Thus, Hibernate first fetches the object (SELECT) and then removes it (DELETE).

Why Hibernate needs to fetch the object first? The reason is that Hibernate interceptors might be enabled (http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/events.html), and the object must be passed through these interceptors to complete its lifecycle. If rows are delete directly in the database, the interceptor won't run.

On the other hand, it's possible to delete entities in one single SQL DELETE statement using bulk operations:

Query q = session.createQuery("delete Entity where id = X");
q.executeUpdate();

When a dictionary is enumerated, it will yield KeyValuePair<TKey,TValue> objects... so you just need to specify "Value" and "Key" for DataTextField and DataValueField respectively, to select the Value/Key properties.

Thanks to Joe's comment, I reread the question to get these the right way round. Normally I'd expect the "key" in the dictionary to be the text that's displayed, and the "value" to be the value fetched. Your sample code uses them the other way round though. Unless you really need them to be this way, you might want to consider writing your code as:

list.Add(cul.DisplayName, cod);

(And then changing the binding to use "Key" for DataTextField and "Value" for DataValueField, of course.)

In fact, I'd suggest that as it seems you really do want a list rather than a dictionary, you might want to reconsider using a dictionary in the first place. You could just use a List<KeyValuePair<string, string>>:

string[] languageCodsList = service.LanguagesAvailable();
var list = new List<KeyValuePair<string, string>>();

foreach (string cod in languageCodsList)
{
    CultureInfo cul = new CultureInfo(cod);
    list.Add(new KeyValuePair<string, string>(cul.DisplayName, cod));
}

Alternatively, use a list of plain CultureInfo values. LINQ makes this really easy:

var cultures = service.LanguagesAvailable()
                      .Select(language => new CultureInfo(language));
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

If you're not using LINQ, you can still use a normal foreach loop:

List<CultureInfo> cultures = new List<CultureInfo>();
foreach (string cod in service.LanguagesAvailable())
{
    cultures.Add(new CultureInfo(cod));
}
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

My approach:

• define a default constraint on the ModDate column with a value of GETDATE() - this handles the INSERT case

• have a AFTER UPDATE trigger to update the ModDate column

Something like:

CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
    UPDATE dbo.TimeEntry
    SET ModDate = GETDATE()
    WHERE ID IN (SELECT DISTINCT ID FROM Inserted)

Why should you learn Python Programming Language?

Python offers a stepping stone into the world of programming. Even though Python Programming Language has been around for 25 years, it is still rising in popularity. Some of the biggest advantage of Python are it's

• Easy to Read & Easy to Learn
• Very productive or small as well as big projects
• Big libraries for many things

What is Python Programming Language used for?

As a general purpose programming language, Python can be used for multiple things. Python can be easily used for small, large, online and offline projects. The best options for utilizing Python are web development, simple scripting and data analysis. Below are a few examples of what Python will let you do:

Web Development:

You can use Python to create web applications on many levels of complexity. There are many excellent Python web frameworks including, Pyramid, Django and Flask, to name a few.

Data Analysis:

Python is the leading language of choice for many data scientists. Python has grown in popularity, within this field, due to its excellent libraries including; NumPy and Pandas and its superb libraries for data visualisation like Matplotlib and Seaborn.

Machine Learning:

What if you could predict customer satisfaction or analyse what factors will affect household pricing or to predict stocks over the next few days, based on previous years data? There are many wonderful libraries implementing machine learning algorithms such as Scikit-Learn, NLTK and TensorFlow.

Computer Vision:

You can do many interesting things such as Face detection, Color detection while using Opencv and Python.

Internet Of Things With Raspberry Pi:

Raspberry Pi is a very tiny and affordable computer which was developed for education and has gained enormous popularity among hobbyists with do-it-yourself hardware and automation. You can even build a robot and automate your entire home. Raspberry Pi can be used as the brain for your robot in order to perform various actions and/or react to the environment. The coding on a Raspberry Pi can be performed using Python. The Possibilities are endless!

Game Development:

Create a video game using module Pygame. Basically, you use Python to write the logic of the game. PyGame applications can run on Android devices.

Web Scraping:

If you need to grab data from a website but the site does not have an API to expose data, use Python to scraping data.

Writing Scripts:

If you're doing something manually and want to automate repetitive stuff, such as emails, it's not difficult to automate once you know the basics of this language.

Browser Automation:

Perform some neat things such as opening a browser and posting a Facebook status, you can do it with Selenium with Python.

GUI Development:

Build a GUI application (desktop app) using Python modules Tkinter, PyQt to support it.

Rapid Prototyping:

Python has libraries for just about everything. Use it to quickly built a (lower-performance, often less powerful) prototype. Python is also great for validating ideas or products for established companies and start-ups alike.

Python can be used in so many different projects. If you're a programmer looking for a new language, you want one that is growing in popularity. As a newcomer to programming, Python is the perfect choice for learning quickly and easily.

I hope this could be helpful for whom has similar problem . In ObjectExplorer window, select your database=> Tables,=> your table=> Constraints. If the customer is defined on create column time, you can see the default name of constraint including the column name. then use:

ALTER TABLE  yourTableName DROP CONSTRAINT DF__YourTa__NewCo__47127295;

(the constraint name is just an example)

This might also help:

void ButtQuitClick(object sender, EventArgs e)
{
    QuitWin form = new QuitWin();
    form.Show();
}

Change ButtQuit to your button name and also change QuitWin to the name of the form that you made.

When the button is clicked it will open another window, you will need to make another form and a button on your main form for it to work.

based on @fabien-snauwaert's answer but simplified if you do not need the original key

$array = array( 'cat' => 'meow', 'dog' => 'woof', 'cow' => 'moo', 'computer' => 'beep' );
foreach( array_values( $array ) as $index=>$value ) {

    // display the current index +  value
    echo $index . ':' . $value;

    // first index
    if ( $index == 0 ) {
        echo ' -- This is the first element in the associative array';
    }

    // last index
    if ( $index == count( $array ) - 1 ) {
        echo ' -- This is the last element in the associative array';
    }
    echo '<br>';
}

for x in numbers:
    print "{:10.4f}".format(x)

prints

   23.2300
    0.1233
    1.0000
    4.2230
 9887.2000

The format specifier inside the curly braces follows the Python format string syntax. Specifically, in this case, it consists of the following parts:

• The empty string before the colon means "take the next provided argument to format()" – in this case the x as the only argument.
• The 10.4f part after the colon is the format specification.
• The f denotes fixed-point notation.
• The 10 is the total width of the field being printed, lefted-padded by spaces.
• The 4 is the number of digits after the decimal point.

The example below shows the basic usage of the FileReader to read the contents of an uploaded file. Here is a working Plunker of this example.

<!DOCTYPE html>
<html>
  <head>
    <script src="script.js"></script>
  </head>

  <body onload="init()">
    <input id="fileInput" type="file" name="file" />
    <pre id="fileContent"></pre>
  </body>
</html>

script.js

function init(){
  document.getElementById('fileInput').addEventListener('change', handleFileSelect, false);
}

function handleFileSelect(event){
  const reader = new FileReader()
  reader.onload = handleFileLoad;
  reader.readAsText(event.target.files[0])
}

function handleFileLoad(event){
  console.log(event);
  document.getElementById('fileContent').textContent = event.target.result;
}

If you are using read only input field, you can use ng-value with filter.

for example:

ng-value="price | number:8"

1) Since the times are dates be sure to use "Date" class, not "POSIXct" or "POSIXlt". See R News 4/1 for advice and try this where Lines is defined in the Note at the end. No packages are used here.

dm <- read.table(text = Lines, header = TRUE)
dm$Date <- as.Date(dm$Date, "%m/%d/%Y")
plot(Visits ~ Date, dm, xaxt = "n", type = "l")
axis(1, dm$Date, format(dm$Date, "%b %d"), cex.axis = .7)

The use of text = Lines is just to keep the example self-contained and in reality it would be replaced with something like "myfile.dat" . (continued after image)

2) Since this is a time series you may wish to use a time series representation giving slightly simpler code:

library(zoo)

z <- read.zoo(text = Lines, header = TRUE, format = "%m/%d/%Y")
plot(z, xaxt = "n")
axis(1, dm$Date, format(dm$Date, "%b %d"), cex.axis = .7)

Depending on what you want the plot to look like it may be sufficient just to use plot(Visits ~ Date, dm) in the first case or plot(z) in the second case suppressing the axis command entirely. It could also be done using xyplot.zoo

library(lattice)
xyplot(z)

or autoplot.zoo:

library(ggplot2)
autoplot(z)

Note:

Lines <- "Date            Visits
11/1/2010   696537
11/2/2010   718748
11/3/2010   799355

Just Right Click on "Python Environment" and Click to "Add Environment"

by is a version of tapply for data frames:

res <- by(group, group$Subject, FUN=function(df) df[which.max(df$pt),])

It returns an object of class by so we convert it to data frame:

do.call(rbind, b)
  Subject pt Event
1       1  5     2
2       2 17     2
3       3  5     2

If you want to remove or unset all $_SESSION 's then try this

session_destroy();

If you want to remove specific $_SESSION['name'] then try this

session_unset('name');

A generic, pure Java solution..

For Windows and MacOS, the following can be inferred (most of the time)...

public static boolean isJDK() {
    String path = System.getProperty("sun.boot.library.path");
    if(path != null && path.contains("jdk")) {
        return true;
    }
    return false;
}

However... on Linux this isn't as reliable... For example...

• Many JREs on Linux contain openjdk the path
• There's no guarantee that the JRE doesn't also contain a JDK.

So a more fail-safe approach is to check for the existence of the javac executable.

public static boolean isJDK() {
    String path = System.getProperty("sun.boot.library.path");
    if(path != null) {
        String javacPath = "";
        if(path.endsWith(File.separator + "bin")) {
            javacPath = path;
        } else {
            int libIndex = path.lastIndexOf(File.separator + "lib");
            if(libIndex > 0) {
                javacPath = path.substring(0, libIndex) + File.separator + "bin";
            }
        }
        if(!javacPath.isEmpty()) {
            return new File(javacPath, "javac").exists() || new File(javacPath, "javac.exe").exists();
        }
    }
    return false;
}

Warning: This will still fail for JRE + JDK combos which report the JRE's sun.boot.library.path identically between the JRE and the JDK. For example, Fedora's JDK will fail (or pass depending on how you look at it) when the above code is run. See unit tests below for more info...

Change 1D array into 2D array without using Numpy.

l = [i for i in range(1,21)]
part = 3
new = []
start, end = 0, part


while end <= len(l):
    temp = []
    for i in range(start, end):
        temp.append(l[i])
    new.append(temp)
    start += part
    end += part
print("new values:  ", new)


# for uneven cases
temp = []
while start < len(l):
    temp.append(l[start])
    start += 1
    new.append(temp)
print("new values for uneven cases:   ", new)

Using your data:

test_data <- data.frame(
var0 = 100 + c(0, cumsum(runif(49, -20, 20))),
var1 = 150 + c(0, cumsum(runif(49, -10, 10))),
Dates = seq.Date(as.Date("2002-01-01"), by="1 month", length.out=100))

I create a stacked version which is what ggplot() would like to work with:

stacked <- with(test_data,
                data.frame(value = c(var0, var1),
                           variable = factor(rep(c("Var0","Var1"),
                                                 each = NROW(test_data))),
                           Dates = rep(Dates, 2)))

In this case producing stacked was quite easy as we only had to do a couple of manipulations, but reshape() and the reshape and reshape2 might be useful if you have a more complex real data set to manipulate.

Once the data are in this stacked form, it only requires a simple ggplot() call to produce the plot you wanted with all the extras (one reason why higher-level plotting packages like lattice and ggplot2 are so useful):

require(ggplot2)
p <- ggplot(stacked, aes(Dates, value, colour = variable))
p + geom_line()

I'll leave it to you to tidy up the axis labels, legend title etc.

HTH

You do that by inserting into position 0:

List myList = new List();
myList.Insert(0, "test");

Rule of thumb: Use -a and -o inside square brackets, && and || outside.

It's important to understand the difference between shell syntax and the syntax of the [ command.

• && and || are shell operators. They are used to combine the results of two commands. Because they are shell syntax, they have special syntactical significance and cannot be used as arguments to commands.

• [ is not special syntax. It's actually a command with the name [, also known as test. Since [ is just a regular command, it uses -a and -o for its and and or operators. It can't use && and || because those are shell syntax that commands don't get to see.

But wait! Bash has a fancier test syntax in the form of [[ ]]. If you use double square brackets, you get access to things like regexes and wildcards. You can also use shell operators like &&, ||, <, and > freely inside the brackets because, unlike [, the double bracketed form is special shell syntax. Bash parses [[ itself so you can write things like [[ $foo == 5 && $bar == 6 ]].

I also have the issue because of i have compile 'com.android.support:appcompat-v7:24.0.0-alpha1' but i added recyclerview liberary compile 'com.android.support:recyclerview-v7:24.0.2'..i changed the version as same as compat like (24.0.2 intead of 24.0.0).

i got the answer..may be it will help for someone.

Reason is to have some value other than zero. General practice to have it short globally and long for long working scripts like parsers, crawlers, dumpers, exporting & importing scripts etc.

1. You can halt server, corrupt work of other people by memory consuming script without even knowing it.
2. You will not be seeing mistakes where something, let's say, infinite loop happened, and it will be harder to diagnose.
3. Such site may be easily DoSed by single user, when requesting pages with long execution time

Along with

<action android:name="android.intent.action.BOOT_COMPLETED" />  

also use,

Just for posterity, here's the text from several external sources regarding the Excel file formats. Some of these have been mentioned in other answers to this question but without reproducing the essential content.

1. From Doug Mahugh, August 22, 2006:

...the new XLSB binary format. Like Open XML, it’s a full-fidelity file format that can store anything you can create in Excel, but the XLSB format is optimized for performance in ways that aren’t possible with a pure XML format.

The XLSB format (also sometimes referred to as BIFF12, as in “binary file format for Office 12”) uses the same Open Packaging Convention used by the Open XML formats and XPS. So it’s basically a ZIP container, and you can open it with any ZIP tool to see what’s inside. But instead of .XML parts within the package, you’ll find .BIN parts...

This article also refers to documentation about the BIN format, too lengthy to reproduce here.

2. From MSDN Archive, August 29, 2006 which in turn cites an already-missing blog post regarding the XLSB format:

Even though we’ve done a lot of work to make sure that our XML formats open quickly and efficiently, this binary format is still more efficient for Excel to open and save, and can lead to some performance improvements for workbooks that contain a lot of data, or that would require a lot of XML parsing during the Open process. (In fact, we’ve found that the new binary format is faster than the old XLS format in many cases.) Also, there is no macro-free version of this file format – all XLSB files can contain macros (VBA and XLM). In all other respects, it is functionally equivalent to the XML file format above:

File size – file size of both formats is approximately the same, since both formats are saved to disk using zip compression Architecture – both formats use the same packaging structure, and both have the same part-level structures. Feature support – both formats support exactly the same feature set Runtime performance – once loaded into memory, the file format has no effect on application/calculation speed Converters – both formats will have identical converter support

If you'd like to use SVN.EXE, there are several companies that compile official binaries that are available for free download. For example, Collabnet:

You can access the first element adding the following code to the highlight function

$(this).find(".selected td:first").html()

As a setter, how about:

// setter
public void beCurrent(boolean X) {
    this.isCurrent = X;
}

or

// setter
public void makeCurrent(boolean X) {
    this.isCurrent = X;
}

I'm not sure if these naming make sense to native English speakers.

Line breaks in text are generally represented as:

\r\n - on a windows computer

\r - on an Apple computer

\n - on Linux

//Removes all 3 types of line breaks

$string = str_replace("\r", "", $string);

$string = str_replace("\n", "", $string);

d = {'A': 4,'B':10}

min_v = min(zip(d.values(), d.keys()))
# min_v is (4,'A')

max_v = max(zip(d.values(), d.keys()))
# max_v is (10,'B')

Try this code:

SharedPreferences sharedPreferences = getSharedPreferences("fake", Context.MODE_PRIVATE);
SharedPreferences.Editor edit = sharedPreferences.edit();
edit.clear().commit();

Try removing package-lock.json file first

The mysql command by default uses UNIX sockets to connect to MySQL.

If you're using MariaDB, you need to load the Unix Socket Authentication Plugin on the server side.

You can do it by editing the [mysqld] configuration like this:

[mysqld]
plugin-load-add = auth_socket.so

Depending on distribution, the config file is usually located at /etc/mysql/ or /usr/local/etc/mysql/

I had the same error with Oracle.DataAccess but deploying to Azure Web Sites (azurewebsites.net). For me I had to edit a setting in VS.NET 2019 before publishing to Azure. I ticked the checkbox "Use the 64 bit version of IIS Express for Web sites and projects" which is found under Tools > Options > Projects and Solutions > Web Projects.

Modern browsers do not currently implement JSONRequest (as far as I know) since it is only a draft right now. I have found someone who has implemented it as a library that you can include in your page: http://devpro.it/JSON/files/JSONRequest-js.html (please note that it has a few dependencies).

Otherwise, you might want to go with another JS library like jQuery or Mootools.

Using /proc/tty/drivers only indicates which tty drivers are loaded. If you're looking for a list of the serial ports check out /dev/serial, it will have two subdirectories: by-id and by-path.

EX:

# find . -type l
./by-path/usb-0:1.1:1.0-port0
./by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller-if00-port0

Thanks to this post: https://superuser.com/questions/131044/how-do-i-know-which-dev-ttys-is-my-serial-port

This post helped me A LOT!

I added UIViewAlertForUnsatisfiableConstraints symbolic breakpoint with suggested action:

Obj-C project

po [[UIWindow keyWindow] _autolayoutTrace]

Swift project

expr -l objc++ -O -- [[UIWindow keyWindow] _autolayoutTrace]

With this hint, the log became more detailed, and It was easier for me identify which view had the constraint broken.

Then I paused execution and I changed problematic view's background color with the command (replacing 0x7f88a8cc2050 with the memory address of your object of course)...

Obj-C

expr ((UIView *)0x7f88a8cc2050).backgroundColor = [UIColor redColor]

Swift 3.0

expr -l Swift -- import UIKit
expr -l Swift -- unsafeBitCast(0x7f88a8cc2050, to: UIView.self).backgroundColor = UIColor.red

... and the result It was awesome!

Simply amazing! Hope It helps.

if you want to stay DRY, use an include.

{% if foo %}
  {% with a as b %}
    {% include "snipet.html" %}
  {% endwith %} 
{% else %}
  {% with bar as b %}
    {% include "snipet.html" %}
  {% endwith %} 
{% endif %}

or, even better would be to write a method on the model that encapsulates the core logic:

def Patient(models.Model):
    ....
    def get_legally_responsible_party(self):
       if self.age > 18:
          return self
       else:
          return self.parent

Then in the template:

{% with patient.get_legally_responsible_party as p %}
  Do html stuff
{% endwith %} 

Then in the future, if the logic for who is legally responsible changes you have a single place to change the logic -- far more DRY than having to change if statements in a dozen templates.

For creating a variable which is read-only in all modules except the one it's declared in:

// Header1.h:

#ifndef SOURCE1_C
   extern const int MyVar;
#endif

// Source1.c:

#define SOURCE1_C
#include Header1.h // MyVar isn't seen in the header

int MyVar; // Declared in this file, and is writeable

// Source2.c

#include Header1.h // MyVar is seen as a constant, declared elsewhere

I hope this would help you!!

The best way to accomplish this is by simply adding "href" to the link button like below.

<asp:LinkButton runat="server" id="SomeLinkButton" href="url" CssClass="btn btn-primary btn-sm">Button Text</asp:LinkButton>

Using javascript, or doing this programmatically in the page_load, will work as well but is not the best way to go about doing this.

You will get this result:

<a id="MainContent_ctl00_SomeLinkButton" class="btn btn-primary btn-sm" href="url" href="javascript:__doPostBack(&#39;ctl00$MainContent$ctl00$lSomeLinkButton&#39;,&#39;&#39;)">Button Text</a>

You can also get the same results by using using a regular <a href="" class=""></a>.

The second option really isn't the same as the others - if the string is "///foo" it will become "foo" instead of "//foo".

The first option needs a bit more work to understand than the third - I would view the Substring option as the most common and readable.

(Obviously each of them as an individual statement won't do anything useful - you'll need to assign the result to a variable, possibly data itself.)

I wouldn't take performance into consideration here unless it was actually becoming a problem for you - in which case the only way you'd know would be to have test cases, and then it's easy to just run those test cases for each option and compare the results. I'd expect Substring to probably be the fastest here, simply because Substring always ends up creating a string from a single chunk of the original input, whereas Remove has to at least potentially glue together a start chunk and an end chunk.

This happens because the current account you have used to log in probably has very limited priviledges.

To fix this problem, you can change your the AllowNoPassword config setting to false in config.inc.php. You may also force the authentication to use the config file and specify the default username and password .

$cfg['Servers'][$i]['AllowNoPassword'] = false;
$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = ''; // leave blank if no password

After this, the PhPMyAdmin login page should show up when you refresh the page. You can then log in with the default root password.

More details can be found on this post ..

Follow these steps- 1.go to config.inc.php file and find - $cfg['Servers'][$i]['auth_type']

2.change the value of $cfg['Servers'][$i]['auth_type'] to 'cookie' or 'http'.

3.find $cfg['Servers'][$i]['AllowNoPassword'] and change it's value to true.

Now whenever you want to login, enter root as your username,skip the password and go ahead pressing the submit button..

Note- if you choose authentication type as cookie then whenever you will close the browser and reopen it ,again you have to login.

here is a useful gist from lfmingo

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

httpClient.addInterceptor(new Interceptor() {

    @Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        Request original = chain.request();

        Request request = original.newBuilder()
            .header("User-Agent", "Your-App-Name")
            .header("Accept", "application/vnd.yourapi.v1.full+json")
            .method(original.method(), original.body())
            .build();

        return chain.proceed(request);
    }
}

OkHttpClient client = httpClient.build();

Retrofit retrofit = new Retrofit.Builder()  
    .baseUrl(API_BASE_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .client(client)
    .build();

I changed all space areas to &nbsp, just like that and it worked without problem.

val.replace(" ", "&nbsp");

I hope it helps someone.

The other answers address the question asked. I will address the underlying cause: poor schema design.

Do not splay an array across columns. Here you have 3*10 columns that should be turned into 10 rows of 3 columns in a new table (plus id, etc)

Your Main table would have only

id  int(11) No       
name    text    No       
date    date    No       
time    time    No       
schedule    int(11) No       
category    int(11) No       
status  int(11) No       
admin_id    int(11) No 

Your extra table (Top) would have

id  int(11) No          -- for joining to Main
seq TINYINT UNSIGNED    -- containing 1..10
img   varchar(255)    No       
title varchar(255)    No       
desc  text    No    
PRIMARY KEY(id, seq)    -- so you can easily find the 10 top_titles

There would be 10 (or fewer? or more?) rows in Top for each id.

This eliminates your original problem, and cleans up the schema. (This is not "normalization", as debated in some of the Comments.)

Do not switch to MyISAM; it is going away.
Don't worry about ROW_FORMAT.

You will need to change your code to do the JOIN and to handle multiple rows instead of multiple columns.

first, get the container id of the desired container by

docker ps

you will get something like this:

CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS                          PORTS                    NAMES
3ac548b6b315        frontend_react-web     "npm run start"     48 seconds ago      Up 47 seconds                   0.0.0.0:3000->3000/tcp   frontend_react-web_1

now copy this container id and run the following command:

docker exec -it container_id sh

docker exec -it 3ac548b6b315 sh

There is no automatic addition of app.config file when you add a class library project to your solution.

To my knowledge, there is no counter indication about doing so manualy. I think this is a common usage.

About log4Net config, you don't have to put the config into app.config, you can have a dedicated conf file in your project as well as an app.config file at the same time.

this link http://logging.apache.org/log4net/release/manual/configuration.html will give you examples about both ways (section in app.config and standalone log4net conf file)

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

Just to document if someone has the same problem...

In my situation I've been using :uuid fields, and the above answers does not work to my case, because rails 5 are creating a column using :bigint instead :uuid:

add_reference :uploads, :user, index: true, type: :uuid

Reference: Active Record Postgresql UUID

You can't "directly" mock static method (hence extension method) with mocking framework. You can try Moles (http://research.microsoft.com/en-us/projects/pex/downloads.aspx), a free tool from Microsoft that implements a different approach. Here is the description of the tool:

Moles is a lightweight framework for test stubs and detours in .NET that is based on delegates.

Moles may be used to detour any .NET method, including non-virtual/static methods in sealed types.

You can use Moles with any testing framework (it's independent about that).

You can use pygame's surfarray module. This module has a 3d pixel array returning method called pixels3d(surface). I've shown usage below:

from pygame import surfarray, image, display
import pygame
import numpy #important to import

pygame.init()
image = image.load("myimagefile.jpg") #surface to render
resolution = (image.get_width(),image.get_height())
screen = display.set_mode(resolution) #create space for display
screen.blit(image, (0,0)) #superpose image on screen
display.flip()
surfarray.use_arraytype("numpy") #important!
screenpix = surfarray.pixels3d(image) #pixels in 3d array:
#[x][y][rgb]
for y in range(resolution[1]):
    for x in range(resolution[0]):
        for color in range(3):
            screenpix[x][y][color] += 128
            #reverting colors
screen.blit(surfarray.make_surface(screenpix), (0,0)) #superpose on screen
display.flip() #update display
while 1:
    print finished

I hope been helpful. Last word: screen is locked for lifetime of screenpix.

If you want to just undo the previous commit's changes to that one file, you can try this:

git checkout branchname^ filename

This will checkout the file as it was before the last commit. If you want to go a few more commits back, use the branchname~n notation.

I have similar situation, I wanted to test if the user is in a certain group. So, I've created new file utils.py where I put all my small utilities that help me through entire application. There, I've have this definition:

utils.py

def is_company_admin(user):
    return user.groups.filter(name='company_admin').exists()

so basically I am testing if the user is in the group company_admin and for clarity I've called this function is_company_admin.

When I want to check if the user is in the company_admin I just do this:

views.py

from .utils import *

if is_company_admin(request.user):
        data = Company.objects.all().filter(id=request.user.company.id)

Now, if you wish to test same in your template, you can add is_user_admin in your context, something like this:

views.py

return render(request, 'admin/users.html', {'data': data, 'is_company_admin': is_company_admin(request.user)})

Now you can evaluate you response in a template:

users.html

{% if is_company_admin %}
     ... do something ...
{% endif %}

Simple and clean solution, based on answers that can be found earlier in this thread, but done differently. Hope it will help someone.

Tested in Django 3.0.4.

I found this somewhere else. I like this answer!

SELECT [Hourly], COUNT(*) as [Count]
  FROM

    FROM table) idat
 GROUP BY [Hourly]

Just wanted to add, that after you remove the package in question you might also need to check to see if it's listed in the list of packages in the following area and manually remove its listing:

Preferences>Package Settings>Package Control>Settings - User

{
    "auto_upgrade_last_run": null,
    "installed_packages":
    [
        "AdvancedNewFile",
        "Emmet",
        "Package Control",
        "SideBarEnhancements",
        "Sublimerge"
    ]
}

In my instance, my trial period for "Sublimerge" had run out and I would get a popup every time I would start Sublime Text 2 saying:

"The package specified, Sublimerge, is not available"

I would have to close the event window out before being able to do anything in ST2.

But in my case, even after successfully removing the package through package control, I still received a event window popup message telling me "Sublimerge" wasn't available. This didn't make any sense as I had successfully removed the package.

It wasn't until I found this "auto_upgrade_last_run" file and manually removed the "Sublimerge" entry and saved my edit, did the message go away.

Using a classmethod with __members__:

class RoleNames(str, Enum):
    AGENT = "agent"
    USER = "user"
    PRIMARY_USER = "primary_user"
    SUPER_USER = "super_user"
    
    @classmethod
    def list_roles(cls):
        role_names = [member.value for role, member in cls.__members__.items()]
        return role_names

>>> role_names = RoleNames.list_roles()
>>> print(role_names)

or if you have multiple Enum classes and want to abstract the classmethod:

class BaseEnum(Enum):
    @classmethod
    def list_roles(cls):
        role_names = [member.value for role, member in cls.__members__.items()]
        return role_names


class RoleNames(str, BaseEnum):    
    AGENT = "agent"
    USER = "user"
    PRIMARY_USER = "primary_user"
    SUPER_USER = "super_user"
    

class PermissionNames(str, BaseEnum):
    READ = "updated_at"
    WRITE = "sort_by"
    READ_WRITE = "sort_order"

truncate tableName

That is what you are looking for.

Truncate will delete all records in the table, emptying it.

I have summarized the existing answers and made sure Node.js is COMPLETELY ERASED along with NPM.

Lines to copy to terminal:

brew uninstall node;
which node;
sudo rm -rf /usr/local/bin/node;
sudo rm -rf /usr/local/lib/node_modules/npm/;
brew doctor;
brew cleanup --prune-prefix;

You can use this method.

    public static File getRobotCacheFile(Context context) throws IOException {
        File cacheFile = new File(context.getCacheDir(), "robot.png");
        try {
            InputStream inputStream = context.getAssets().open("robot.png");
            try {
                FileOutputStream outputStream = new FileOutputStream(cacheFile);
                try {
                    byte[] buf = new byte[1024];
                    int len;
                    while ((len = inputStream.read(buf)) > 0) {
                        outputStream.write(buf, 0, len);
                    }
                } finally {
                    outputStream.close();
                }
            } finally {
                inputStream.close();
            }
        } catch (IOException e) {
            throw new IOException("Could not open robot png", e);
        }
        return cacheFile;
    }

You should never use InputStream.available() in such cases. It returns only bytes that are buffered. Method with .available() will never work with bigger files and will not work on some devices at all.

In Kotlin (;D):

@Throws(IOException::class)
fun getRobotCacheFile(context: Context): File = File(context.cacheDir, "robot.png")
    .also {
        it.outputStream().use { cache -> context.assets.open("robot.png").use { it.copyTo(cache) } }
    }

The public keyword is used only when declaring a class method.

Since you're declaring a simple function and not a class you need to remove public from your code.

I faced the same issue and got the same deprecation warning. I was using a numpy array of [23, 276] when I got the message. I tried reshaping it as per the warning and end up in nowhere. Then I select each row from the numpy array (as I was iterating over it anyway) and assigned it to a list variable. It worked then without any warning.

array = []
array.append(temp[0])

Then you can use the python list object (here 'array') as an input to sk-learn functions. Not the most efficient solution, but worked for me.

You can join a table to itself as many times as you require, it is called a self join.

An alias is assigned to each instance of the table (as in the example below) to differentiate one from another.

SELECT a.SelfJoinTableID
FROM   dbo.SelfJoinTable a
       INNER JOIN dbo.SelfJoinTable b
         ON a.SelfJoinTableID = b.SelfJoinTableID
       INNER JOIN dbo.SelfJoinTable c
         ON a.SelfJoinTableID = c.SelfJoinTableID
WHERE  a.Status = 'Status to filter a'
       AND b.Status = 'Status to filter b'
       AND c.Status = 'Status to filter c' 

Use git clone with the --depth option set to 1 to create a shallow clone with a history truncated to the latest commit.

For example:

git clone --depth 1 https://github.com/user/repo.git

To also initialize and update any nested submodules, also pass --recurse-submodules and to clone them shallowly, also pass --shallow-submodules.

For example:

git clone --depth 1 --recurse-submodules --shallow-submodules https://github.com/user/repo.git

Using static cast would probably result in something like this:

// This does not prevent a possible type overflow
const char char_max = -1;

int i = 48;
char c = (i & char_max);

To prevent possible type overflow you could do this:

const char char_max = (char)(((unsigned char) char(-1)) / 2);

int i = 128;
char c = (i & char_max); // Would always result in positive signed values.

Where reinterpret_cast would probably just directly convert to char, without any cast safety. -> Never use reinterpret_cast if you can also use static_cast. If you're casting between classes, static_cast will also ensure, that the two types are matching (the object is a derivate of the cast type).

If your object a polymorphic type and you don't know which one it is, you should use dynamic_cast which will perform a type check at runtime and return nullptr if the types do not match.

IF you need const_cast you most likely did something wrong and should think about possible alternatives to fix const correctness in your code.

Here's a way to do this using TPL. No need to create/dispose of a timer, etc:

void ScheduleSomething()
{

    var runAt = DateTime.Today + TimeSpan.FromHours(16);

    if (runAt <= DateTime.Now)
    {
        DoSomething();
    }
    else
    {
        var delay = runAt - DateTime.Now;
        System.Threading.Tasks.Task.Delay(delay).ContinueWith(_ => DoSomething());
    }

}

void DoSomething()
{
    // do somethig
}

In the latest version of pandas (0.19.2) you can directly pass the url

import pandas as pd

url="https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv"
c=pd.read_csv(url)

One alternative is to represent your 2D array as a 1D array. This can make element-wise operations more efficient. You should probably wrap it in a class that would also contain width and height.

Another alternative is to represent a 2D array as an std::vector<std::vector<int> >. This will let you use STL's algorithms for array arithmetic, and the vector will also take care of memory management for you.

does

$('#elem').css('-webkit-transition','none !important'); 

in your js kill it?

obviously repeat for each.

Using Java 8 Streams:

Map<Object, Object> map = new HashMap<>();

String content = map.entrySet()
                    .stream()
                    .map(e -> e.getKey() + "=\"" + e.getValue() + "\"")
                    .collect(Collectors.joining(", "));

System.out.println(content);

Sometimes, when all else fails, you just want to tell pandas to shut up about it:

# Ignore DtypeWarnings from pandas' read_csv                                                                                                                                                                                            
warnings.filterwarnings('ignore', message="^Columns.*")

I got this error when I was using the app icon image which was resized to 120x120 from 180x180 sized icon using the preview app on MAC. The error is gone When I removed the 120x120 icon from the project. Resizing icons can mess-up with the format required by Apple.

I created a StackOverflow account JUST to answer this question. After fruitlessly searching the interwebs I just wrote something myself. This is how I did it so it can be applied to any mongoose model. Either import this function or add it directly into your code where you are doing the updating.

function upsertObject (src, dest) {

  function recursiveFunc (src, dest) {
    _.forOwn(src, function (value, key) {
      if(_.isObject(value) && _.keys(value).length !== 0) {
        dest[key] = dest[key] || {};
        recursiveFunc(src[key], dest[key])
      } else if (_.isArray(src) && !_.isObject(src[key])) {
          dest.set(key, value);
      } else {
        dest[key] = value;
      }
    });
  }

  recursiveFunc(src, dest);

  return dest;
}

Then to upsert a mongoose document do the following,

YourModel.upsert = function (id, newData, callBack) {
  this.findById(id, function (err, oldData) {
    if(err) {
      callBack(err);
    } else {
      upsertObject(newData, oldData).save(callBack);
    }
  });
};

This solution may require 2 DB calls however you do get the benefit of,

• Schema validation against your model because you are using .save()
• You can upsert deeply nested objects without manual enumeration in your update call, so if your model changes you do not have to worry about updating your code

Just remember that the destination object will always override the source even if the source has an existing value

Also, for arrays, if the existing object has a longer array than the one replacing it then the values at the end of the old array will remain. An easy way to upsert the entire array is to set the old array to be an empty array before the upsert if that is what you are intending on doing.

UPDATE - 01/16/2016 I added an extra condition for if there is an array of primitive values, Mongoose does not realize the array becomes updated without using the "set" function.

It probably means that your MySQL server is only listening the localhost interface.

If you have lines like this :

bind-address = 127.0.0.1

In your my.cnf configuration file, you should comment them (add a # at the beginning of the lines), and restart MySQL.

sudo service mysql restart

Of course, to do this, you must be the administrator of the server.

Thanks to this site by Mkyong, the only solution that actually worked for us to pass a parameter was this

<h:commandLink action="#{user.editAction}">
    <f:param name="myId" value="#{param.id}" />
</h:commandLink>

with

public String editAction() {

  Map<String,String> params = 
            FacesContext.getExternalContext().getRequestParameterMap();
  String idString = params.get("myId");
  long id = Long.parseLong(idString);
  ...
}

Technically, that you cannot pass to the method itself directly, but to the JSF request parameter map.

I think it's to prevent you from mixing declarations and definitions. (Think about the problems that could occur if you include the file in multiple places.)

#pragma comment is a compiler directive which indicates Visual C++ to leave a comment in the generated object file. The comment can then be read by the linker when it processes object files.

#pragma comment(lib, libname) tells the linker to add the 'libname' library to the list of library dependencies, as if you had added it in the project properties at Linker->Input->Additional dependencies

See #pragma comment on MSDN

This has nothing to do with the MULTILINE flag; what you're seeing is the difference between the find() and matches() methods. find() succeeds if a match can be found anywhere in the target string, while matches() expects the regex to match the entire string.

Pattern p = Pattern.compile("xyz");

Matcher m = p.matcher("123xyzabc");
System.out.println(m.find());    // true
System.out.println(m.matches()); // false

Matcher m = p.matcher("xyz");
System.out.println(m.matches()); // true

Furthermore, MULTILINE doesn't mean what you think it does. Many people seem to jump to the conclusion that you have to use that flag if your target string contains newlines--that is, if it contains multiple logical lines. I've seen several answers here on SO to that effect, but in fact, all that flag does is change the behavior of the anchors, ^ and $.

Normally ^ matches the very beginning of the target string, and $ matches the very end (or before a newline at the end, but we'll leave that aside for now). But if the string contains newlines, you can choose for ^ and $ to match at the start and end of any logical line, not just the start and end of the whole string, by setting the MULTILINE flag.

So forget about what MULTILINE means and just remember what it does: changes the behavior of the ^ and $ anchors. DOTALL mode was originally called "single-line" (and still is in some flavors, including Perl and .NET), and it has always caused similar confusion. We're fortunate that the Java devs went with the more descriptive name in that case, but there was no reasonable alternative for "multiline" mode.

In Perl, where all this madness started, they've admitted their mistake and gotten rid of both "multiline" and "single-line" modes in Perl 6 regexes. In another twenty years, maybe the rest of the world will have followed suit.

As you said, you can't really do it because of type erasure. You can sort of do it using reflection, but it requires a lot of code and lot of error handling.

In my application I ended up with two different elements having the same id (bad). One element was a div and the other an input. I was trying to sum up my inputs and took me a while to realise the duplicate ids. By placing the type of the element I wanted in front of #, I was able to grab the value of the input element and discard the div:

$("input#_myelementid").val();

I hope it helps.

Here is small utility class that converts JSON to DataFrame and back: Hope you find this helpful.

This particular NuGet package has a habit of losing its references in one of our projects. From time to time I will need to run the following command in the Package Manager Console to restore the references and everything is OK again

Update-Package Microsoft.AspNet.Webpages -reinstall

bundle update gem-name [--major|--patch|--minor]

This also works for dependencies.

I've written down this macro

#define IS_EMPTY_STR(X) ( (1 / (sizeof(X[0]) == 1))/*type check*/ && !(X[0])/*content check*/)

so it would be

while (! IS_EMPTY_STR(url));

The benefit in this macro it that it's type-safe. You'll get a compilation error if put in something other than a pointer to char.

JSONArray jsonArray = new JSONArray(yourJsonString);

for (int i = 0; i < jsonArray.length(); i++) {
     JSONObject obj1 = jsonArray.getJSONObject(i);
     JSONArray results = patient.getJSONArray("results");
     String indexForPhone =  patientProfile.getJSONObject(0).getString("indexForPhone"));
}

Change to JSONArray, then convert to JSONObject.

For value types, you can use Marshal.SizeOf. Of course, it returns the number of bytes required to marshal the structure in unmanaged memory, which is not necessarily what the CLR uses.

Only this worked for me:

$(document).ready(function(){
    $('select').not('.disabled').formSelect();
});

Use a Comparator:

List<CustomObject> list = new ArrayList<CustomObject>();
Comparator<CustomObject> comparator = new Comparator<CustomObject>() {
    @Override
    public int compare(CustomObject left, CustomObject right) {
        return left.getId() - right.getId(); // use your logic
    }
};

Collections.sort(list, comparator); // use the comparator as much as u want
System.out.println(list);

Additionally, if CustomObjectimplements Comparable, then just use Collections.sort(list)

With JDK 8 the syntax is much simpler.

List<CustomObject> list = getCustomObjectList();
Collections.sort(list, (left, right) -> left.getId() - right.getId());
System.out.println(list);

Much simplier

List<CustomObject> list = getCustomObjectList();
list.sort((left, right) -> left.getId() - right.getId());
System.out.println(list);

Simplest

List<CustomObject> list = getCustomObjectList();
list.sort(Comparator.comparing(CustomObject::getId));
System.out.println(list);

Obviously the initial code can be used for JDK 8 too.

Your string may contain non Latin1 characters, which leads to undefined data. It depends of what you mean by "it deosn't seem to work".

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication
