A char doesn't have any methods - it's a Java primitive. You're looking for the Character wrapper class.

The usage would be:

if(Character.isLetter(ch)) { //... }

The reason why you're getting that error is because you've declared your struct as:

struct {
 char name[32];
 int  size;
 int  start;
 int  popularity;
} stasher_file;

This is not declaring a stasher_file type. This is declaring an anonymous struct type and is creating a global instance named stasher_file.

What you intended was:

struct stasher_file {
 char name[32];
 int  size;
 int  start;
 int  popularity;
};

But note that while Brian R. Bondy's response wasn't correct about your error message, he's right that you're trying to write into the struct without having allocated space for it. If you want an array of pointers to struct stasher_file structures, you'll need to call malloc to allocate space for each one:

struct stasher_file *newFile = malloc(sizeof *newFile);
if (newFile == NULL) {
   /* Failure handling goes here. */
}
strncpy(newFile->name, name, 32);
newFile->size = size;
...

(BTW, be careful when using strncpy; it's not guaranteed to NUL-terminate.)

Reviewing the basic terminology

It's usually good enough - unless you're programming assembly - to envisage a pointer containing a numeric memory address, with 1 referring to the second byte in the process's memory, 2 the third, 3 the fourth and so on....

• What happened to 0 and the first byte? Well, we'll get to that later - see null pointers below.
• For a more accurate definition of what pointers store, and how memory and addresses relate, see "More about memory addresses, and why you probably don't need to know" at the end of this answer.

When you want to access the data/value in the memory that the pointer points to - the contents of the address with that numerical index - then you dereference the pointer.

Different computer languages have different notations to tell the compiler or interpreter that you're now interested in the pointed-to object's (current) value - I focus below on C and C++.

A pointer scenario

Consider in C, given a pointer such as p below...

const char* p = "abc";

...four bytes with the numerical values used to encode the letters 'a', 'b', 'c', and a 0 byte to denote the end of the textual data, are stored somewhere in memory and the numerical address of that data is stored in p. This way C encodes text in memory is known as ASCIIZ.

For example, if the string literal happened to be at address 0x1000 and p a 32-bit pointer at 0x2000, the memory content would be:

Memory Address (hex)    Variable name    Contents
1000                                     'a' == 97 (ASCII)
1001                                     'b' == 98
1002                                     'c' == 99
1003                                     0
...
2000-2003               p                1000 hex

Note that there is no variable name/identifier for address 0x1000, but we can indirectly refer to the string literal using a pointer storing its address: p.

Dereferencing the pointer

To refer to the characters p points to, we dereference p using one of these notations (again, for C):

assert(*p == 'a');  // The first character at address p will be 'a'
assert(p[1] == 'b'); // p[1] actually dereferences a pointer created by adding
                     // p and 1 times the size of the things to which p points:
                     // In this case they're char which are 1 byte in C...
assert(*(p + 1) == 'b');  // Another notation for p[1]

You can also move pointers through the pointed-to data, dereferencing them as you go:

++p;  // Increment p so it's now 0x1001
assert(*p == 'b');  // p == 0x1001 which is where the 'b' is...

If you have some data that can be written to, then you can do things like this:

int x = 2;
int* p_x = &x;  // Put the address of the x variable into the pointer p_x
*p_x = 4;       // Change the memory at the address in p_x to be 4
assert(x == 4); // Check x is now 4

Above, you must have known at compile time that you would need a variable called x, and the code asks the compiler to arrange where it should be stored, ensuring the address will be available via &x.

Dereferencing and accessing a structure data member

In C, if you have a variable that is a pointer to a structure with data members, you can access those members using the -> dereferencing operator:

typedef struct X { int i_; double d_; } X;
X x;
X* p = &x;
p->d_ = 3.14159;  // Dereference and access data member x.d_
(*p).d_ *= -1;    // Another equivalent notation for accessing x.d_

Multi-byte data types

To use a pointer, a computer program also needs some insight into the type of data that is being pointed at - if that data type needs more than one byte to represent, then the pointer normally points to the lowest-numbered byte in the data.

So, looking at a slightly more complex example:

double sizes[] = { 10.3, 13.4, 11.2, 19.4 };
double* p = sizes;
assert(p[0] == 10.3);  // Knows to look at all the bytes in the first double value
assert(p[1] == 13.4);  // Actually looks at bytes from address p + 1 * sizeof(double)
                       // (sizeof(double) is almost always eight bytes)
++p;                   // Advance p by sizeof(double)
assert(*p == 13.4);    // The double at memory beginning at address p has value 13.4
*(p + 2) = 29.8;       // Change sizes[3] from 19.4 to 29.8
                       // Note earlier ++p and + 2 here => sizes[3]

Pointers to dynamically allocated memory

Sometimes you don't know how much memory you'll need until your program is running and sees what data is thrown at it... then you can dynamically allocate memory using malloc. It is common practice to store the address in a pointer...

int* p = (int*)malloc(sizeof(int)); // Get some memory somewhere...
*p = 10;            // Dereference the pointer to the memory, then write a value in
fn(*p);             // Call a function, passing it the value at address p
(*p) += 3;          // Change the value, adding 3 to it
free(p);            // Release the memory back to the heap allocation library

In C++, memory allocation is normally done with the new operator, and deallocation with delete:

int* p = new int(10); // Memory for one int with initial value 10
delete p;

p = new int[10];      // Memory for ten ints with unspecified initial value
delete[] p;

p = new int[10]();    // Memory for ten ints that are value initialised (to 0)
delete[] p;

See also C++ smart pointers below.

Losing and leaking addresses

Often a pointer may be the only indication of where some data or buffer exists in memory. If ongoing use of that data/buffer is needed, or the ability to call free() or delete to avoid leaking the memory, then the programmer must operate on a copy of the pointer...

const char* p = asprintf("name: %s", name);  // Common but non-Standard printf-on-heap

// Replace non-printable characters with underscores....
for (const char* q = p; *q; ++q)
    if (!isprint(*q))
        *q = '_';

printf("%s\n", p); // Only q was modified
free(p);

...or carefully orchestrate reversal of any changes...

const size_t n = ...;
p += n;
...
p -= n;  // Restore earlier value...
free(p);

C++ smart pointers

In C++, it's best practice to use smart pointer objects to store and manage the pointers, automatically deallocating them when the smart pointers' destructors run. Since C++11 the Standard Library provides two, unique_ptr for when there's a single owner for an allocated object...

{
    std::unique_ptr<T> p{new T(42, "meaning")};
    call_a_function(p);
    // The function above might throw, so delete here is unreliable, but...
} // p's destructor's guaranteed to run "here", calling delete

...and shared_ptr for share ownership (using reference counting)...

{
    auto p = std::make_shared<T>(3.14, "pi");
    number_storage1.may_add(p); // Might copy p into its container
    number_storage2.may_add(p); // Might copy p into its container    } // p's destructor will only delete the T if neither may_add copied it

Null pointers

In C, NULL and 0 - and additionally in C++ nullptr - can be used to indicate that a pointer doesn't currently hold the memory address of a variable, and shouldn't be dereferenced or used in pointer arithmetic. For example:

const char* p_filename = NULL; // Or "= 0", or "= nullptr" in C++
int c;
while ((c = getopt(argc, argv, "f:")) != -1)
    switch (c) {
      case f: p_filename = optarg; break;
    }
if (p_filename)  // Only NULL converts to false
    ...   // Only get here if -f flag specified

In C and C++, just as inbuilt numeric types don't necessarily default to 0, nor bools to false, pointers are not always set to NULL. All these are set to 0/false/NULL when they're static variables or (C++ only) direct or indirect member variables of static objects or their bases, or undergo zero initialisation (e.g. new T(); and new T(x, y, z); perform zero-initialisation on T's members including pointers, whereas new T; does not).

Further, when you assign 0, NULL and nullptr to a pointer the bits in the pointer are not necessarily all reset: the pointer may not contain "0" at the hardware level, or refer to address 0 in your virtual address space. The compiler is allowed to store something else there if it has reason to, but whatever it does - if you come along and compare the pointer to 0, NULL, nullptr or another pointer that was assigned any of those, the comparison must work as expected. So, below the source code at the compiler level, "NULL" is potentially a bit "magical" in the C and C++ languages...

More about memory addresses, and why you probably don't need to know

More strictly, initialised pointers store a bit-pattern identifying either NULL or a (often virtual) memory address.

The simple case is where this is a numeric offset into the process's entire virtual address space; in more complex cases the pointer may be relative to some specific memory area, which the CPU may select based on CPU "segment" registers or some manner of segment id encoded in the bit-pattern, and/or looking in different places depending on the machine code instructions using the address.

For example, an int* properly initialised to point to an int variable might - after casting to a float* - access memory in "GPU" memory quite distinct from the memory where the int variable is, then once cast to and used as a function pointer it might point into further distinct memory holding machine opcodes for the program (with the numeric value of the int* effectively a random, invalid pointer within these other memory regions).

3GL programming languages like C and C++ tend to hide this complexity, such that:

• If the compiler gives you a pointer to a variable or function, you can dereference it freely (as long as the variable's not destructed/deallocated meanwhile) and it's the compiler's problem whether e.g. a particular CPU segment register needs to be restored beforehand, or a distinct machine code instruction used

• If you get a pointer to an element in an array, you can use pointer arithmetic to move anywhere else in the array, or even to form an address one-past-the-end of the array that's legal to compare with other pointers to elements in the array (or that have similarly been moved by pointer arithmetic to the same one-past-the-end value); again in C and C++, it's up to the compiler to ensure this "just works"

• Specific OS functions, e.g. shared memory mapping, may give you pointers, and they'll "just work" within the range of addresses that makes sense for them

• Attempts to move legal pointers beyond these boundaries, or to cast arbitrary numbers to pointers, or use pointers cast to unrelated types, typically have undefined behaviour, so should be avoided in higher level libraries and applications, but code for OSes, device drivers, etc. may need to rely on behaviour left undefined by the C or C++ Standard, that is nevertheless well defined by their specific implementation or hardware.

this error usually shows if the name of your struct is different from the initialization of your struct in the code, so normally, c will find the name of the struct you put and if the original struct is not found, this would usually appear, or if you point a pointer pointed into that pointer, the error will show up.

C also does a good job at not making anything ambiguous.

Sure the dot could be overloaded to mean both things, but the arrow makes sure that the programmer knows that he's operating on a pointer, just like when the compiler won't let you mix two incompatible types.

I've always heard them used in the opposite sense:

• & is the reference operator -- it gives you a reference (pointer) to some object

• * is the dereference operator -- it takes a reference (pointer) and gives you back the referred to object;

You can try the following VBA code to export Macro contents directly without converting them to VBA first. Unlike Tables, Forms, Reports, and Modules, the Macros are in a container called Scripts. But they are there and can be exported and imported using SaveAsText and LoadFromText

Option Compare Database

Option Explicit

Public Sub ExportDatabaseObjects()
On Error GoTo Err_ExportDatabaseObjects

    Dim db As Database
    Dim d As Document
    Dim c As Container
    Dim sExportLocation As String

    Set db = CurrentDb()

    sExportLocation = "C:\SomeFolder\"
    Set c = db.Containers("Scripts")
    For Each d In c.Documents
        Application.SaveAsText acMacro, d.Name, sExportLocation & "Macro_" & d.Name & ".txt"
    Next d

An alternative object to use is as follows:

  For Each obj In Access.Application.CurrentProject.AllMacros
    Access.Application.SaveAsText acMacro, obj.Name, strFilePath & "\Macro_" & obj.Name & ".txt"
  Next

To check if variable v is not set

if [ "$v" == "" ]; then

Your question is a little unclear, but if what you're doing is trying to get your friend's latest changes, then typically what your friend needs to do is to push those changes up to a remote repo (like one hosted on GitHub), and then you fetch or pull those changes from the remote:

1. Your friend pushes his changes to GitHub:

   git push origin <branch>
   

2. Clone the remote repository if you haven't already:

   git clone https://[email protected]/abc/theproject.git
   

3. Fetch or pull your friend's changes (unnecessary if you just cloned in step #2 above):

   git fetch origin
   git merge origin/<branch>
   

   Note that git pull is the same as doing the two steps above:

   git pull origin <branch>

This answer currently only applies to using two Linux computers [or maybe works on Mac too?--untested on Mac] (syncing from one to the other) because I wrote this synchronization script in bash. It is simply a wrapper around git, however, so feel free to take it and convert it into a cross-platform Python solution or something if you wish

This doesn't directly answer the OP's question, but it is so close I guarantee it will answer many other peoples' question who land on this page (mine included, actually, as I came here first before writing my own solution), so I'm posting it here anyway.

I want to:

1. develop code using a powerful IDE like Eclipse on a light-weight Linux computer, then
2. build that code via ssh on a different, more powerful Linux computer (from the command-line, NOT from inside Eclipse)

Let's call the first computer where I write the code "PC1" (Personal Computer 1), and the 2nd computer where I build the code "PC2". I need a tool to easily synchronize from PC1 to PC2. I tried rsync, but it was insanely slow for large repos and took tons of bandwidth and data.

So, how do I do it? What workflow should I use? If you have this question too, here's the workflow that I decided upon. I wrote a bash script to automate the process by using git to automatically push changes from PC1 to PC2 via a remote repository, such as github. So far it works very well and I'm very pleased with it. It is far far far faster than rsync, more trustworthy in my opinion because each PC maintains a functional git repo, and uses far less bandwidth to do the whole sync, so it's easily doable over a cell phone hot spot without using tons of your data.

Setup:

1. Install the script on PC1 (this solution assumes ~/bin is in your $PATH):

   git clone https://github.com/ElectricRCAircraftGuy/eRCaGuy_dotfiles.git
   cd eRCaGuy_dotfiles/useful_scripts
   mkdir -p ~/bin
   ln -s "${PWD}/sync_git_repo_from_pc1_to_pc2.sh" ~/bin/sync_git_repo_from_pc1_to_pc2
   cd ..
   cp -i .sync_git_repo ~/.sync_git_repo
   

2. Now edit the "~/.sync_git_repo" file you just copied above, and update its parameters to fit your case. Here are the parameters it contains:

   # The git repo root directory on PC2 where you are syncing your files TO; this dir must *already exist* 
   # and you must have *already `git clone`d* a copy of your git repo into it!
   # - Do NOT use variables such as `$HOME`. Be explicit instead. This is because the variable expansion will 
   #   happen on the local machine when what we need is the variable expansion from the remote machine. Being 
   #   explicit instead just avoids this problem.
   PC2_GIT_REPO_TARGET_DIR="/home/gabriel/dev/eRCaGuy_dotfiles" # explicitly type this out; don't use variables
   
   PC2_SSH_USERNAME="my_username" # explicitly type this out; don't use variables
   PC2_SSH_HOST="my_hostname"     # explicitly type this out; don't use variables
   

3. Git clone your repo you want to sync on both PC1 and PC2.

4. Ensure your ssh keys are all set up to be able to push and pull to the remote repo from both PC1 and PC2. Here's some helpful links:
   1. https://help.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh
   2. https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
5. Ensure your ssh keys are all set up to ssh from PC1 to PC2.

6. Now cd into any directory within the git repo on PC1, and run:

   sync_git_repo_from_pc1_to_pc2
   

7. That's it! About 30 seconds later everything will be magically synced from PC1 to PC2, and it will be printing output the whole time to tell you what it's doing and where it's doing it on your disk and on which computer. It's safe too, because it doesn't overwrite or delete anything that is uncommitted. It backs it up first instead! Read more below for how that works.

Here's the process this script uses (ie: what it's actually doing)

1. From PC1: It checks to see if any uncommitted changes are on PC1. If so, it commits them to a temporary commit on the current branch. It then force pushes them to a remote SYNC branch. Then it uncommits its temporary commit it just did on the local branch, then it puts the local git repo back to exactly how it was by staging any files that were previously staged at the time you called the script. Next, it rsyncs a copy of the script over to PC2, and does an ssh call to tell PC2 to run the script with a special option to just do PC2 stuff.
2. Here's what PC2 does: it cds into the repo, and checks to see if any local uncommitted changes exist. If so, it creates a new backup branch forked off of the current branch (sample name: my_branch_SYNC_BAK_20200220-0028hrs-15sec <-- notice that's YYYYMMDD-HHMMhrs--SSsec), and commits any uncommitted changes to that branch with a commit message such as DO BACKUP OF ALL UNCOMMITTED CHANGES ON PC2 (TARGET PC/BUILD MACHINE). Now, it checks out the SYNC branch, pulling it from the remote repository if it is not already on the local machine. Then, it fetches the latest changes on the remote repository, and does a hard reset to force the local SYNC repository to match the remote SYNC repository. You might call this a "hard pull". It is safe, however, because we already backed up any uncommitted changes we had locally on PC2, so nothing is lost!
3. That's it! You now have produced a perfect copy from PC1 to PC2 without even having to ensure clean working directories, as the script handled all of the automatic committing and stuff for you! It is fast and works very well on huge repositories. Now you have an easy mechanism to use any IDE of your choice on one machine while building or testing on another machine, easily, over a wifi hot spot from your cell phone if needed, even if the repository is dozens of gigabytes and you are time and resource-constrained.

What you want to do is actually again a groupby (on the result of the first groupby): sort and take the first three elements per group.

Starting from the result of the first groupby:

In [60]: df_agg = df.groupby(['job','source']).agg({'count':sum})

We group by the first level of the index:

In [63]: g = df_agg['count'].groupby('job', group_keys=False)

Then we want to sort ('order') each group and take the first three elements:

In [64]: res = g.apply(lambda x: x.sort_values(ascending=False).head(3))

However, for this, there is a shortcut function to do this, nlargest:

In [65]: g.nlargest(3)
Out[65]:
job     source
market  A         5
        D         4
        B         3
sales   E         7
        C         6
        B         4
dtype: int64

So in one go, this looks like:

df_agg['count'].groupby('job', group_keys=False).nlargest(3)

You can also use IFNA(expression, value)

Modern Versions of PostgreSQL

Suppose you have a table named test1, to which you want to add an auto-incrementing, primary-key id (surrogate) column. The following command should be sufficient in recent versions of PostgreSQL:

   ALTER TABLE test1 ADD COLUMN id SERIAL PRIMARY KEY;

Older Versions of PostgreSQL

In old versions of PostgreSQL (prior to 8.x?) you had to do all the dirty work. The following sequence of commands should do the trick:

  ALTER TABLE test1 ADD COLUMN id INTEGER;
  CREATE SEQUENCE test_id_seq OWNED BY test1.id;
  ALTER TABLE test ALTER COLUMN id SET DEFAULT nextval('test_id_seq');
  UPDATE test1 SET id = nextval('test_id_seq');

Again, in recent versions of Postgres this is roughly equivalent to the single command above.

The answer to the question depends. There are 2 scenarios in this situation and you'll need to make a choice based on your appropriate scenario.

Scenario 1 - Critical script / Must needed script

In case the script you are using is important to load the website, it is recommended to be placed at the top of your HTML document i.e, <head>. Some examples include - application code, bootstrap, fonts, etc.

Scenario 2 - Less important / analytics scripts

There are also scripts used which do not affect the website's view. Such scripts are recommended to be loaded after all the important segments are loaded. And the answer to that will be bottom of the document i.e, bottom of your <body> before the closing tag. Some examples include - Google analytics, hotjar, etc.

Bonus - async / defer

You can also tell the browsers that the script loading can be done simultaneously with others and can be loaded based on the browser's choice using a defer / async argument in the script code.

eg. <script async src="script.js"></script>

In my case adding Microsoft.AspNet.WebApi.Owin reference via nuget did the trick.

Format with Currency format string

=Format(Fields!Price.Value, "C")

It will give you 2 decimal places with "$" prefixed.

You can find other format strings on MSDN: Adding Style and Formatting to a ReportViewer Report

Note: The MSDN article has been archived to the "VS2005_General" document, which is no longer directly accessible online. Here is the excerpt of the formatting strings referenced:

Formatting Numbers

The following table lists common .NET Framework number formatting strings.

Format string, Name

C or c Currency

D or d Decimal

E or e Scientific

F or f Fixed-point

G or g General

N or n Number

P or p Percentage

R or r Round-trip

X or x Hexadecimal

You can modify many of the format strings to include a precision specifier that defines the number of digits to the right of the

decimal point. For example, a formatting string of D0 formats the number so that it has no digits after the decimal point. You

can also use custom formatting strings, for example, #,###.

Formatting Dates

The following table lists common .NET Framework date formatting strings.

Format string, Name

d Short date

D Long date

t Short time

T Long time

f Full date/time (short time)

F Full date/time (long time)

g General date/time (short time)

G General date/time (long time)

M or m Month day

R or r RFC1123 pattern

Y or y Year month

You can also a use custom formatting strings; for example, dd/MM/yy. For more information about .NET Framework formatting strings, see Formatting Types.

Also, if you have arcanist installed (correction: Uber's fork of arcanist installed--see the bottom of this answer here for installation instructions), arc flow shows a beautiful dependency tree of upstream dependencies (ie: which were set previously via arc flow new_branch or manually via git branch --set-upstream-to=upstream_branch).

If you're working with Visual Studio then follow these steps to access the IIS-Express over IP-Adress:

1. Get your host IP-Adress: ipconfig in Windows Command Line

2. GoTo

   $(SolutionDir)\.vs\config\applicationHost.config
   

3. Find

   <site name="WebApplication3" id="2">
      <application path="/" applicationPool="Clr4IntegratedAppPool">
         <virtualDirectory path="/" physicalPath="C:\Users\user.name\Source\Repos\protoype-one\WebApplication3" />
      </application>
      <bindings>
        <binding protocol="http" bindingInformation="*:62549:localhost" />
      </bindings>
   </site>
   

4. Add: <binding protocol="http" bindingInformation="*:62549:192.168.178.108"/>
   with your IP-Adress

5. Run your Visual Studio with Administrator rights and everything should work
6. Maybe look for some firewall issues if you try to connect from remote

And here is a quick benchmark for both #sample and #rand:

irb(main):014:0* Benchmark.bm do |x|
irb(main):015:1*   x.report('sample') { 1_000_000.times { (1..100).to_a.sample } }
irb(main):016:1>   x.report('rand') { 1_000_000.times { rand(1..100) } }
irb(main):017:1> end
       user     system      total        real
sample  3.870000   0.020000   3.890000 (  3.888147)
rand  0.150000   0.000000   0.150000 (  0.153557)

So, doing rand(a..b) is the right thing

According to the CI docs (CodeIgniter Email Library)...

If you prefer not to set preferences using the above method, you can instead put them into a config file. Simply create a new file called the email.php, add the $config array in that file. Then save the file at config/email.php and it will be used automatically. You will NOT need to use the $this->email->initialize() function if you save your preferences in a config file.

I was able to get this to work by putting all the settings into application/config/email.php.

$config['useragent'] = 'CodeIgniter';
$config['protocol'] = 'smtp';
//$config['mailpath'] = '/usr/sbin/sendmail';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'YOURPASSWORDHERE';
$config['smtp_port'] = 465; 
$config['smtp_timeout'] = 5;
$config['wordwrap'] = TRUE;
$config['wrapchars'] = 76;
$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['validate'] = FALSE;
$config['priority'] = 3;
$config['crlf'] = "\r\n";
$config['newline'] = "\r\n";
$config['bcc_batch_mode'] = FALSE;
$config['bcc_batch_size'] = 200;

Then, in one of the controller methods I have something like:

$this->load->library('email'); // Note: no $config param needed
$this->email->from('[email protected]', '[email protected]');
$this->email->to('[email protected]');
$this->email->subject('Test email from CI and Gmail');
$this->email->message('This is a test.');
$this->email->send();

Also, as Cerebro wrote, I had to uncomment out this line in my php.ini file and restart PHP:

extension=php_openssl.dll

I'm going to assume compiling the QuickFix package does not produce a setup.py file, but rather only compiles the Python bindings and relies on make install to put them in the appropriate place.

In this case, a quick and dirty fix is to compile the QuickFix source, locate the Python extension modules (you indicated on your system these end with a .so extension), and add that directory to your PYTHONPATH environmental variable e.g., add

export PYTHONPATH=~/path/to/python/extensions:PYTHONPATH

or similar line in your shell configuration file.

A more robust solution would include making sure to compile with ./configure --prefix=$HOME/.local. Assuming QuickFix knows to put the Python files in the appropriate site-packages, when you do make install, it should install the files to ~/.local/lib/pythonX.Y/site-packages, which, for Python 2.6+, should already be on your Python path as the per-user site-packages directory.

If, on the other hand, it did provide a setup.py file, simply run

python setup.py install --user

for Python 2.6+.

you can't use VALUES clause when inserting data using another SELECT query. see INSERT SYNTAX

INSERT INTO user
(
 id, name, username, email, opted_in
)
(
    SELECT id, name, username, email, opted_in
    FROM user
         LEFT JOIN user_permission AS userPerm
            ON user.id = userPerm.user_id
);

$(document).ready(function() {
  $('#div_one').bind('click', function() {
    $('#div_two').addClass('large');
  });
});

If I understood your question.

Or you can modify css directly:

var $speech = $('div.speech');
var currentSize = $speech.css('fontSize');
$speech.css('fontSize', '10px');

java.time

Java 8 introduced a new API for working with dates and times: the java.time package.

With java.time you can parse your count of whole seconds since the epoch reference of first moment of 1970 in UTC, 1970-01-01T00:00Z. The result is an Instant.

Instant instant = Instant.ofEpochSecond( timeStamp );

If you need a java.util.Date to interoperate with old code not yet updated for java.time, convert. Call new conversion methods added to the old classes.

Date date = Date.from( instant );

time1 is the key of the most outer dictionary, eg, feb2012. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:

for info in courses[time1][course]:

As you're going through each dictionary, you must add another nest.

I'm late to the party but I encountered the same thing when I tried to get fancy and move my library and then had files being saved to a folder that was outdated:

.libloc <<- "C:/Program Files/rest_of_your_Library_FileName"

One other point to mention is that for Windows Computers, if you copy the address from Windows Explorer, you have to manually change the '\' to a '/' for the directory to be recognized.

Even it is not a good way of doing what you want try this hint: var url = MUST BE A NUMER FIRST

function nextImage (){
url = url + 1;  
location.href='http://mywebsite.com/' + url+'.html';
}

Here is my version of the same task::

import os, glob, shutil

def make_dir(path):
    if not os.path.isdir(path):
        os.mkdir(path)


def copy_dir(source_item, destination_item):
    if os.path.isdir(source_item):
        make_dir(destination_item)
        sub_items = glob.glob(source_item + '/*')
        for sub_item in sub_items:
            copy_dir(sub_item, destination_item + '/' + sub_item.split('/')[-1])
    else:
        shutil.copy(source_item, destination_item)

Here's an pretty useless function that return values wrapped by specific characters. :)

jsfiddle: https://jsfiddle.net/squadjot/43agwo6x/

function getValsWrappedIn(str,c1,c2){
    var rg = new RegExp("(?<=\\"+c1+")(.*?)(?=\\"+c2+")","g"); 
    return str.match(rg);
    }

var exampleStr = "Something (5) or some time (19) or maybe a (thingy)";
var results =  getValsWrappedIn(exampleStr,"(",")")

// Will return array ["5","19","thingy"]
console.log(results)

I agree that @DaveAbrahams's answer using the bisect module is the correct approach. He did not mention one important detail in his answer.

From the docs bisect.bisect_left(a, x, lo=0, hi=len(a))

The bisection module does not require the search array to be precomputed ahead of time. You can just present the endpoints to the bisect.bisect_left instead of it using the defaults of 0 and len(a).

Even more important for my use, looking for a value X such that the error of a given function is minimized. To do that, I needed a way to have the bisect_left's algorithm call my computation instead. This is really simple.

Just provide an object that defines __getitem__ as a

For example, we could use the bisect algorithm to find a square root with arbitrary precision!

import bisect

class sqrt_array(object):
    def __init__(self, digits):
        self.precision = float(10**(digits))
    def __getitem__(self, key):
        return (key/self.precision)**2.0

sa = sqrt_array(4)

# "search" in the range of 0 to 10 with a "precision" of 0.0001
index = bisect.bisect_left(sa, 7, 0, 10*10**4)
print 7**0.5
print index/(10**4.0)

Check out MySQL Server Time Zone Support and the system_time_zone system variable. Does that help?

This works too and also demonstrates how to change the legend title:

ggplot(df, aes(x, y, colour=g)) +
  geom_line(stat="identity") + 
  theme(legend.position="bottom") +
  scale_color_discrete(name="")

It seems that you've omitted the value attribute in HTML markup.

Add it there as <input value="" ... >.

YOu can also rewrite it like this

FROM Resource r WHERE r.ResourceNo IN
        ( 
            SELECT m.ResourceNo FROM JobMember m
            JOIN Job j ON j.JobNo = m.JobNo
            WHERE j.ProjectManagerNo = @UserResourceNo 
            OR
            j.AlternateProjectManagerNo = @UserResourceNo

            Union All

            SELECT m.ResourceNo FROM JobMember m
            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
            WHERE t.TaskManagerNo = @UserResourceNo
            OR
            t.AlternateTaskManagerNo = @UserResourceNo

        )

Also a return table is expected in your RETURN statement

More concisely:

! particular_script

From the POSIX specification regarding set -e (emphasis mine):

When this option is on, if a simple command fails for any of the reasons listed in Consequences of Shell Errors or returns an exit status value >0, and is not part of the compound list following a while, until, or if keyword, and is not a part of an AND or OR list, and is not a pipeline preceded by the ! reserved word, then the shell shall immediately exit.

Answer for "pre-Java-9" is below. As of Java 9, properties files are saved and loaded in UTF-8 by default, but falling back to ISO-8859-1 if an invalid UTF-8 byte sequence is detected. See the Java 9 release notes for details.

Properties files are ISO-8859-1 by definition - see the docs for the Properties class.

Spring has a replacement which can load with a specified encoding, using PropertiesFactoryBean.

EDIT: As Laurence noted in the comments, Java 1.6 introduced overloads for load and store which take a Reader/Writer. This means you can create a reader for the file with whatever encoding you want, and pass it to load. Unfortunately FileReader still doesn't let you specify the encoding in the constructor (aargh) so you'll be stuck with chaining FileInputStream and InputStreamReader together. However, it'll work.

For example, to read a file using UTF-8:

Properties properties = new Properties();
InputStream inputStream = new FileInputStream("path/to/file");
try {
    Reader reader = new InputStreamReader(inputStream, "UTF-8");
    try {
        properties.load(reader);
    } finally {
        reader.close();
    }
} finally {
   inputStream.close();
}

The point is that the first line of your codes is not what you expected.

You should use:

val map = scala.collection.mutable.Map[A,B]()

You then have multiple equivalent alternatives to add items:

scala> val map = scala.collection.mutable.Map[String,String]()
map: scala.collection.mutable.Map[String,String] = Map()


scala> map("k1") = "v1"

scala> map
res1: scala.collection.mutable.Map[String,String] = Map((k1,v1))


scala> map += "k2" -> "v2"
res2: map.type = Map((k1,v1), (k2,v2))


scala> map.put("k3", "v3")
res3: Option[String] = None

scala> map
res4: scala.collection.mutable.Map[String,String] = Map((k3,v3), (k1,v1), (k2,v2))

And starting Scala 2.13:

scala> map.addOne("k4" -> "v4")
res5: map.type = HashMap(k1 -> v1, k2 -> v2, k3 -> v3, k4 -> v4)

I have created a JSFiddle with my bindHTML knockout binding handler here: https://jsfiddle.net/glaivier/9859uq8t/

First, save the binding handler into its own (or a common) file and include after Knockout.

If you use this switch your bindings to this:

<div data-bind="bindHTML: htmlValue"></div>

OR

<!-- ko bindHTML: htmlValue --><!-- /ko -->

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

Prepared statements / parameterized queries are generally sufficient to prevent 1st order injection on that statement^*. If you use un-checked dynamic sql anywhere else in your application you are still vulnerable to 2nd order injection.

2nd order injection means data has been cycled through the database once before being included in a query, and is much harder to pull off. AFAIK, you almost never see real engineered 2nd order attacks, as it is usually easier for attackers to social-engineer their way in, but you sometimes have 2nd order bugs crop up because of extra benign ' characters or similar.

You can accomplish a 2nd order injection attack when you can cause a value to be stored in a database that is later used as a literal in a query. As an example, let's say you enter the following information as your new username when creating an account on a web site (assuming MySQL DB for this question):

' + (SELECT UserName + '_' + Password FROM Users LIMIT 1) + '

If there are no other restrictions on the username, a prepared statement would still make sure that the above embedded query doesn't execute at the time of insert, and store the value correctly in the database. However, imagine that later the application retrieves your username from the database, and uses string concatenation to include that value a new query. You might get to see someone else's password. Since the first few names in users table tend to be admins, you may have also just given away the farm. (Also note: this is one more reason not to store passwords in plain text!)

We see, then, that prepared statements are enough for a single query, but by themselves they are not sufficient to protect against sql injection attacks throughout an entire application, because they lack a mechanism to enforce all access to a database within an application uses safe code. However, used as part of good application design — which may include practices such as code review or static analysis, or use of an ORM, data layer, or service layer that limits dynamic sql — prepared statements are the primary tool for solving the Sql Injection problem. If you follow good application design principles, such that your data access is separated from the rest of your program, it becomes easy to enforce or audit that every query correctly uses parameterization. In this case, sql injection (both first and second order) is completely prevented.

_{^*It turns out that MySql/PHP are (okay, were) just dumb about handling parameters when wide characters are involved, and there is still a rare case outlined in the other highly-voted answer here that can allow injection to slip through a parameterized query.}

If you don't like libraries, how about this?

Note that you should not use this function on the whole URL, instead you should use this on the components...e.g. just the "a b" component, as you build up the URL - otherwise the computer won't know what characters are supposed to have a special meaning and which ones are supposed to have a literal meaning.

/** Converts a string into something you can safely insert into a URL. */
public static String encodeURIcomponent(String s)
{
    StringBuilder o = new StringBuilder();
    for (char ch : s.toCharArray()) {
        if (isUnsafe(ch)) {
            o.append('%');
            o.append(toHex(ch / 16));
            o.append(toHex(ch % 16));
        }
        else o.append(ch);
    }
    return o.toString();
}

private static char toHex(int ch)
{
    return (char)(ch < 10 ? '0' + ch : 'A' + ch - 10);
}

private static boolean isUnsafe(char ch)
{
    if (ch > 128 || ch < 0)
        return true;
    return " %$&+,/:;=?@<>#%".indexOf(ch) >= 0;
}

Add display: block; and overflow: auto; to .my-table. This will simply cut off anything past the 280px limit you enforced. There's no way to make it "look pretty" with that requirement due to words like pélagosthrough which are wider than 280px.

This is the way to iterate on this array:

foreach($hotels as $row) {
       foreach($row['rooms'] as $k) {
             echo $k['boards']['board_id'];
             echo $k['boards']['price'];
       }
}

You want to iterate on the hotels and the rooms (the ones with numeric indexes), because those seem to be the "collections" in this case. The other arrays only hold and group properties.

You can use which.

x<-c(1:5)
x
#[1] 1 2 3 4 5
x<-x[-which(x==4)]
x
#[1] 1 2 3 5

I'm also struggled with the same problem, and this is my solution.

HTML source

<div class="input_width">
    <input type="text" class="form-control input-lg" placeholder="sample">
</div>

Cover input code with another div class

CSS source

.input_width{
   width: 450px;
}

give any width or margin setting on covered div class.

Bootstrap's input width is always default as 100%, so width is follow that covered width.

This is not the best way, but easiest and only solution that I solved the problem.

Hope this helped.

Echoing the answer, above, a full install of the JDK (8u121 at this writing) from here - http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html - did the trick. Updating via the Mac OS Control Panel did not update the profile variable. Installing via the full installer, did. Then Eclipse was happy.

Carry Flag is a flag set when:

a) two unsigned numbers were added and the result is larger than "capacity" of register where it is saved. Ex: we wanna add two 8 bit numbers and save result in 8 bit register. In your example: 255 + 9 = 264 which is more that 8 bit register can store. So the value "8" will be saved there (264 & 255 = 8) and CF flag will be set.

b) two unsigned numbers were subtracted and we subtracted the bigger one from the smaller one. Ex: 1-2 will give you 255 in result and CF flag will be set.

Auxiliary Flag is used as CF but when working with BCD. So AF will be set when we have overflow or underflow on in BCD calculations. For example: considering 8 bit ALU unit, Auxiliary flag is set when there is carry from 3rd bit to 4th bit i.e. carry from lower nibble to higher nibble. (Wiki link)

Overflow Flag is used as CF but when we work on signed numbers. Ex we wanna add two 8 bit signed numbers: 127 + 2. the result is 129 but it is too much for 8bit signed number, so OF will be set. Similar when the result is too small like -128 - 1 = -129 which is out of scope for 8 bit signed numbers.

You can read more about flags on wikipedia

grep -r -e string directory

-r is for recursive; -e is optional but its argument specifies the regex to search for. Interestingly, POSIX grep is not required to support -r (or -R), but I'm practically certain that System V grep did, so in practice they (almost) all do. Some versions of grep support -R as well as (or conceivably instead of) -r; AFAICT, it means the same thing.

First of all, you should never use the money datatype. If you do any calculations you will get truncated results. Run the following to see what I mean

DECLARE
    @mon1 MONEY,
    @mon2 MONEY,
    @mon3 MONEY,
    @mon4 MONEY,
    @num1 DECIMAL(19,4),
    @num2 DECIMAL(19,4),
    @num3 DECIMAL(19,4),
    @num4 DECIMAL(19,4)

    SELECT
    @mon1 = 100, @mon2 = 339, @mon3 = 10000,
    @num1 = 100, @num2 = 339, @num3 = 10000

    SET @mon4 = @mon1/@mon2*@mon3
    SET @num4 = @num1/@num2*@num3

    SELECT @mon4 AS moneyresult,
    @num4 AS numericresult

Output: 2949.0000 2949.8525

Now to answer your question (it was a little vague), the money datatype always has two places after the decimal point. Use the integer datatype if you don't want the fractional part or convert to int.

Perhaps you want to use the decimal or numeric datatype?

If you want to avoid a DirectoryNotFoundException you will need to ensure that the directory of the file does indeed exist. File.Exists accomplishes this. Another way would be to utilize the Path and Directory utility classes like so:

string file = @"C:\subfolder\test.txt";
if (Directory.Exists(Path.GetDirectoryName(file)))
{
    File.Delete(file);
}

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

The div tag is a block element, causing that behavior.

You should use a span element instead, which is inline.

If you really want to use div, add style="display: inline". (You can also put that in a CSS rule)

I have done this code in case anyone faced my problem of adding lots of fields fast using MySQl code hope it helps , u can run this code on any online php compiler as well if u are too busy!

$fields = array(

        'col_two' ,
        'col_three'

    );

    $startF = 'after_col';
    $table = 'table_name';

    $output = 'ALTER TABLE ' .$table.'<br>';
    for($i=0 ; $i<count($fields) ; $i++){
        if($i==0){
            $output.= 'ADD COLUMN '.$fields[$i].' VARCHAR(15) AFTER '.$startF.',' . '<br>';

        }else{
            $output.= 'ADD COLUMN '.$fields[$i].' VARCHAR(15) AFTER '.$fields[$i-1].',' . '<br>';

        }
    }

// extra fields without the array

    $output.= 'ADD COLUMN col_four VARCHAR(255) AFTER any_col_u_want,  '. '<br>';
    $output.= 'ADD COLUMN col_five VARCHAR(255) AFTER col_four,  '. '<br>';
    $output.= 'ADD COLUMN col_six VARCHAR(255) AFTER col_five'. '<br>';



    echo $output;

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

please remove any unusable jar file and try to run. and its work for me i added a jcommons jar file and also another jcommons.1.0.14 jar file so remove jcommons and its working for me

The closest thing to what you're looking for is the :first-child pseudoclass; unfortunately this will not work in your case because you have an <h1> before the <div>s. What I would suggest is that you either add a class to the <div>, like <div class="first"> and then style it that way, or use jQuery if you really can't add a class:

$('#content > div:first')

Nvm Nvm is a script-based node version manager. You can install it easily with a curl and bash one-liner as described in the documentation. It's also available on Homebrew.

Assuming you have successfully installed nvm. The following will install the latest version of node.

 nvm install node --reinstall-packages-from=node

The last option installs all global npm packages over to your new version. This way packages like mocha and node-inspector keep working.

N N is an npm-based node version manager. You can install it by installing first some version of node and then running npm install -g n.

Assuming you have successfully installed n. The following will install the latest version of node.

sudo n latest

Homebrew Homebrew is one of the two popular package managers for Mac. Assuming you have previously installed node with brew install node. You can get up-to-date with formulae and upgrade to the latest Node.js version with the following.

1 brew update
2 brew upgrade node

MacPorts MacPorts is the another package manager for Mac. The following will update the local ports tree to get access to updated versions. Then it will install the latest version of Node.js. This works even if you have previous version of the package installed.

1 sudo port selfupdate
2 sudo port install nodejs-devel

An easy way to install Java 7 on a Mac is by using Homebrew, thanks to the Homebrew Cask plugin (which is now installed by default).

Run this command to install Java 7:

brew cask install caskroom/versions/java7

:unchecked is not defined in the Selectors or CSS UI level 3 specs, nor has it appeared in level 4 of Selectors.

In fact, the quote from W3C is taken from the Selectors 4 spec. Since Selectors 4 recommends using :not(:checked), it's safe to assume that there is no corresponding :unchecked pseudo. Browser support for :not() and :checked is identical, so that shouldn't be a problem.

This may seem inconsistent with the :enabled and :disabled states, especially since an element can be neither enabled nor disabled (i.e. the semantics completely do not apply), however there does not appear to be any explanation for this inconsistency.

(:indeterminate does not count, because an element can similarly be neither unchecked, checked nor indeterminate because the semantics don't apply.)

I came here through Google looking for an answer to how to setup cloud init to not disable PasswordAuthentication on AWS. Both the answers don't address the issue. Without it, if you create an AMI then on instance initialization cloud init will again disable this option.

The correct method to do this, is instead of manually changing sshd_config you need to correct the setting for cloud init (Open source tool used to configure an instance during provisioning. Read more at: https://cloudinit.readthedocs.org/en/latest/). The configuration file for cloud init is found at: /etc/cloud/cloud.cfg

This file is used for setting up a lot of the configuration used by cloud init. Read through this file for examples of items you can configure on cloud-init. This includes items like default username on a newly created instance)

To enable or disable password login over SSH you need to change the value for the parameter ssh_pwauth. After changing the parameter ssh_pwauth from 0 to 1 in the file /etc/cloud/cloud.cfg bake an AMI. If you launch from this newly baked AMI it will have password authentication enabled after provisioning.

You can confirm this by checking the value of the PasswordAuthentication in the ssh config as mentioned in the other answers.

I'm not really sure of your question, but if all you really want is list currently opened screen session, try:

screen -ls

While a few of these answers will get you in the ballpark, you cannot do what you're trying to do with arbitrary dates for SqlServer 2005 and earlier because of daylight savings time. Using the difference between the current local and current UTC will give me the offset as it exists today. I have not found a way to determine what the offset would have been for the date in question.

That said, I know that SqlServer 2008 provides some new date functions that may address that issue, but folks using an earlier version need to be aware of the limitations.

Our approach is to persist UTC and perform the conversion on the client side where we have more control over the conversion's accuracy.

This is not a direct answer to your question (which was answered pretty well already). However, having had times bite me on the fundament several times, I cannot stress enough that it would behoove you to look closely at what your time.struct_time object is providing, vs. what other time fields may have.

Assuming you have both a time.struct_time object, and some other date/time string, compare the two, and be sure you are not losing data and inadvertently creating a naive datetime object, when you can do otherwise.

For example, the excellent feedparser module will return a "published" field and may return a time.struct_time object in its "published_parsed" field:

time.struct_time(tm_year=2013, tm_mon=9, tm_mday=9, tm_hour=23, tm_min=57, tm_sec=42, tm_wday=0, tm_yday=252, tm_isdst=0)

Now note what you actually get with the "published" field.

Mon, 09 Sep 2013 19:57:42 -0400

By Stallman's Beard! Timezone information!

In this case, the lazy man might want to use the excellent dateutil module to keep the timezone information:

from dateutil import parser
dt = parser.parse(entry["published"])
print "published", entry["published"])
print "dt", dt
print "utcoffset", dt.utcoffset()
print "tzinfo", dt.tzinfo
print "dst", dt.dst()

which gives us:

published Mon, 09 Sep 2013 19:57:42 -0400
dt 2013-09-09 19:57:42-04:00
utcoffset -1 day, 20:00:00
tzinfo tzoffset(None, -14400)
dst 0:00:00

One could then use the timezone-aware datetime object to normalize all time to UTC or whatever you think is awesome.

being a newbie here i can't yet directly comment but here is a small correction i'd like to add to the following part of ??O?????'s answer :

If you prefer full pathnames, then use this function:

def listdirs(folder):  
  return [
    d for d in (os.path.join(folder, d1) for d1 in os.listdir(folder))
    if os.path.isdir(d)
]

for those still on python < 2.4: the inner construct needs to be a list instead of a tuple and therefore should read like this:

def listdirs(folder):  
  return [
    d for d in [os.path.join(folder, d1) for d1 in os.listdir(folder)]
    if os.path.isdir(d)
  ]

otherwise one gets a syntax error.

It might also make sense to add a call to clearNotifications in applicationDidBecomeActive so that in case the application is in the background and comes back it will also clear the notifications.

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [self clearNotifications];
}

Following should work

$d = strtotime("+1 months",strtotime("2015-05-25"));
echo   date("Y-m-d",$d); // This will print **2015-06-25** 

I'm not sure if PyQt does have a script like this, but after you install PySide there is a script in pythons script directory "uic.py". You can use this script to convert a .ui file to a .py file:

python uic.py input.ui -o output.py -x

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

With React Navigation v5, just use the navigate method. From the docs:

To achieve this, you can use the navigate method, which acts like goBack if the screen already exists. You can pass the params with navigate to pass the data back

Full example:

import React from 'react';
import { StyleSheet, Button, Text, View } from 'react-native';

import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

function ScreenA ({ navigation, route }) {
  const { params } = route;

  return (
    <View style={styles.container}>
      <Text>Params: {JSON.stringify(params)}</Text>
      <Button title='Go to B' onPress={() => navigation.navigate('B')} />
    </View>
  );
}

function ScreenB ({ navigation }) {
  return (
    <View style={styles.container}>
      <Button title='Go to A'
        onPress={() => {
          navigation.navigate('A', { data: 'Something' })
        }}
      />
    </View>
  );
}

export default function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator mode="modal">
        <Stack.Screen name="A" component={ScreenA} />
        <Stack.Screen name="B" component={ScreenB} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

use textstyle property as bold

android:textStyle = "bold";

Converting your lists to sets will tell you that they contain the same elements. But this method cannot confirm that they contain the same number of all elements. For example, your method will fail in this case:

L1 = [1,2,2,3]
L2 = [1,2,3,3]

You are likely better off sorting the two lists and comparing them:

def checkEqual(L1, L2):
    if sorted(L1) == sorted(L2):
        print "the two lists are the same"
        return True
    else:
        print "the two lists are not the same"
        return False

Note that this does not alter the structure/contents of the two lists. Rather, the sorting creates two new lists

I think you want SELECT * FROM INFORMATION_SCHEMA.TABLES

See http://dev.mysql.com/doc/refman/5.0/en/tables-table.html

Right click on you image to get resolution. In my case 1233 x 882

const { width } = Dimensions.get('window');

const ratio = 882 / 1233;

    const style = {
      width,
      height: width * ratio
    }

<Image source={image} style={style} resizeMode="contain" />

That all

If you are using oc4j to deploy the ear.

Make sure you set in the project the correct path for deploy.home=

You can fiind deploy.home in common.properties file

The oc4j needs to reload the new created class in the ear so that the server class and the client class have the same serialVersionUID

If you are using Spring 3, the easiest way is:

 @RequestMapping(method = RequestMethod.GET)   
 public ModelAndView showResults(final HttpServletRequest request, Principal principal) {

     final String currentUser = principal.getName();

 }

I fixed it with adding the prefix (attr.) :

<create-report-card-form [attr.currentReportCardCount]="expression" ...

Unfortunately this haven't documented properly yet.

You are right, the second Dockerfile will overwrite the CMD command of the first one. Docker will always run a single command, not more. So at the end of your Dockerfile, you can specify one command to run. Not more.

But you can execute both commands in one line:

FROM centos+ssh
EXPOSE 22
EXPOSE 4149
CMD service sshd start && /opt/mq/sbin/rabbitmq-server start

What you could also do to make your Dockerfile a little bit cleaner, you could put your CMD commands to an extra file:

FROM centos+ssh
EXPOSE 22
EXPOSE 4149
CMD sh /home/centos/all_your_commands.sh

And a file like this:

service sshd start &
/opt/mq/sbin/rabbitmq-server start

Answer to your question is NO.

Correct is MyString[position of character]. For your case MyString[0], 0 is the FIRST character of any string.

A character value is designated with ' (single quote), like this x character value is written as 'x'.

A string value is designated with " ( double quote), like this x string value is written as "x".

So Substring() method is also does not return a character, Substring() method returns a string!!!

A string is an array of characters, and last character must be '\0' (null) character. Thats the difference between character array and string ( which is an array of characters with last character as "end of string marker" '\0' null.

And also notice that 'x' IS NOT EQUAL to "x". Because "x" is actually 'x'+'\0'.

I do not know whether this is the general opinion, but I've always differentiated the two by what they are used for. An emulator is used if you actually want to use the emulated machine for its output. A simulator, on the other hand, is for when you want to study the simulated machine or test its behaviour.

For example, if you want to write some state machine logic in your application (which is running on a general purpose CPU), you write a small state machine emulator. If you want to study the efficiency or viability of a state machine for a particular problem, you write a simulator.

Standard SQL disallows references to column aliases in a WHERE clause. This restriction is imposed because when the WHERE clause is evaluated, the column value may not yet have been determined. For example, the following query is illegal:

SELECT id, COUNT(*) AS cnt FROM tbl_name WHERE cnt > 0 GROUP BY id;

• Angular Core v6.0.2,
• Angular Material, v6.0.2,
• Angular CLI v6.0.0 (globally v6.1.2)

I had this issue when running ng test, so to fix it, I added to my xyz.component.spec.ts file:

import { MatTableModule } from '@angular/material';

And added it to imports section in TestBed.configureTestingModule({}):

beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [ ReactiveFormsModule, HttpClientModule, RouterTestingModule, MatTableModule ],
      declarations: [ BookComponent ],
      schemas: [ CUSTOM_ELEMENTS_SCHEMA ]
    })
    .compileComponents();
}));

For me the issue wasn't six but rst2pdf itself. head -1 $(which rst2pdf) (3.8) didn't match python3 --version (3.9). My solution:

pip3 install rst2pdf

Jetty is a great way to easily embed an HTTP server. It supports it's own simple way to attach handlers and is a full J2EE app server if you need more functionality.

No, you don't need to add them as a remote. That would be clumbersome and a pain to do each time.

Grabbing their commits:

git fetch [email protected]:theirusername/reponame.git theirbranch:ournameforbranch

This creates a local branch named ournameforbranch which is exactly the same as what theirbranch was for them. For the question example, the last argument would be foo:foo.

Note :ournameforbranch part can be further left off if thinking up a name that doesn't conflict with one of your own branches is bothersome. In that case, a reference called FETCH_HEAD is available. You can git log FETCH_HEAD to see their commits then do things like cherry-picked to cherry pick their commits.

Pushing it back to them:

Oftentimes, you want to fix something of theirs and push it right back. That's possible too:

git fetch [email protected]:theirusername/reponame.git theirbranch
git checkout FETCH_HEAD

# fix fix fix

git push [email protected]:theirusername/reponame.git HEAD:theirbranch

If working in detached state worries you, by all means create a branch using :ournameforbranch and replace FETCH_HEAD and HEAD above with ournameforbranch.

The ENTER key merely activates the form's default submit button, which will be the first

<input type="submit" />

the browser finds within the form.

Therefore don't have a submit button, but something like

<input type="button" value="Submit" onclick="submitform()" /> 

EDIT: In response to discussion in comments:

This doesn't work if you have only one text field - but it may be that is the desired behaviour in that case.

The other issue is that this relies on Javascript to submit the form. This may be a problem from an accessibility point of view. This can be solved by writing the <input type='button'/> with javascript, and then put an <input type='submit' /> within a <noscript> tag. The drawback of this approach is that for javascript-disabled browsers you will then have form submissions on ENTER. It is up to the OP to decide what is the desired behaviour in this case.

I know of no way of doing this without invoking javascript at all.

I needed my ASP.NET drop down list to take up all available space, and this is all I put in the CSS and it is working in Firefox and IE11:

width: 100%

I had to add the CSS class into the asp:DropDownList element

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

Create an XML file named border.xml in the drawable folder and put the following code in it.

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item> 
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" /> 
    </shape>
  </item>   
    <item android:left="5dp" android:right="5dp"  android:top="5dp" >  
     <shape android:shape="rectangle"> 
      <solid android:color="#000000" />
    </shape>
   </item>    
 </layer-list> 

Then add a background to your linear layout like this:

         android:background="@drawable/border"

EDIT :

This XML was tested with a galaxy s running GingerBread 2.3.3 and ran perfectly as shown in image below:

ALSO

tested with galaxy s 3 running JellyBean 4.1.2 and ran perfectly as shown in image below :

Finally its works perfectly with all APIs

EDIT 2 :

It can also be done using a stroke to keep the background as transparent while still keeping a border except at the bottom with the following code.

<?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:left="0dp" android:right="0dp"  android:top="0dp"  
        android:bottom="-10dp"> 
    <shape android:shape="rectangle">
     <stroke android:width="10dp" android:color="#B22222" />
    </shape>
   </item>  
 </layer-list> 

hope this help .

First, your HTML markup looks like this:

<video id="awesome_video" src="first_video.mp4" autoplay />

Second, your JavaScript code will look like this:

<script type="text/javascript">
  var index = 1,
      playlist = ['first_video.mp4', 'second_video.mp4', 'third_video.mp4'],
      video = document.getElementById('awesome_video');

  video.addEventListener('ended', rotate_video, false);

  function rotate_video() {
    video.setAttribute('src', playlist[index]);
    video.load();
    index++;
    if (index >= playlist.length) { index = 0; }
  }
</script>

And last but not least, your CSS:

#awesome_video { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

This will create a video element on your page that starts playing the first video right away, then iterates through the playlist defined by the JavaScript variable. Your mileage with the CSS may vary depending on the CSS for the rest of the site, but 100% width/height should do it on a basic page.

I wrote a drawable lib to custom round corner position, it looks like this:

You can get this lib at here:

Setting up insets in Interface Builder like shown in the screenshot below

Will result in something like this:

Apparently match_parent is :

• NOT OK for views directly under ConstraintLayout
• OK for views nested inside of views that are directly under ConstraintLayout

So if you need your views to function as match_parent, then:

1. Direct children of ConstraintLayout should use 0dp
2. Nested elements (eg, grandchild to ConstraintLayout) can use match_parent

Example:

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="16dp">

    <android.support.design.widget.TextInputLayout
        android:id="@+id/phoneNumberInputLayout"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/phoneNumber"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

    </android.support.design.widget.TextInputLayout>

svn status | grep ^M will list files which are modified. M - stands for modified :)

First you should inject IConfiguration and then for reading from appsettings, you can use one of this methods:

1. Get a section data

   var redisConfig = configuration.GetSection("RedisConfig");
   

2. Get a value within a section

   var redisServer = configuration.GetValue<string>("RedisConfig:ServerName");
   

3. Get nested value within section

   var redisExpireMInutes = configuration.GetValue<int>("RedisConfig:ServerName:ExpireMInutes");
   

I think it is better to use Array.Exists than Array.FindAll.

You may want to consider using SCLAlertView, alternative for UIAlertView or UIAlertController.

UIAlertController only works on iOS 8.x or above, SCLAlertView is a good option to support older version.

github to see the details

example:

let alertView = SCLAlertView()
alertView.addButton("First Button", target:self, selector:Selector("firstButton"))
alertView.addButton("Second Button") {
    print("Second button tapped")
}
alertView.showSuccess("Button View", subTitle: "This alert view has buttons")

Im not sure if this is the "Professional" way to do it and i'm not entirely sure if it works for everything.

    }
} while ( gotError = true );

I just had this issue after installing and removing some npm packages and spent almost 5 hours to figure out what was going on.

What I did is basically copied my src/components in a different directory, then removed all the node modules and package-lock.json (if you are running your app in the Docker container, remove images and rebuild it just to be safe); then reset it to my last commit and then put back my src/components then ran npm i.

I hope it helps.

BufferedImage img = ImageIO.read(new ByteArrayInputStream(bytes));

Here is the solution I found: On the project tree "app", right click mouse button to get the context menu. Select "open module setting", on the tree "app" - "properties" tab, select the existing "build tools version" you have. The gradle will start to build.

Try https://github.com/tmpvar/jsdom - you give it some HTML and it gives you a DOM.

In my case, with GitHub Desktop for Windows (as of June 2, 2016) & Android Studio 2.1:

This folder ->

C:\Users\(UserName)\AppData\Local\GitHub\PortableGit_<hash>\

Contained a BATCH file called something like 'post-install.bat'. Run this file to create a folder 'cmd' with 'git.exe' inside.

This path-->

C:\Users\(UserName)\AppData\Local\GitHub\PortableGit_<hash>\cmd\git.exe

would be the location of 'git.exe' after running the post-install script.

Well, I had the same trouble ... so I found this thread

I think the answer from user:"pmg" does not work always.

unsigned int int_to_int(unsigned int k) {
    return (k == 0 || k == 1 ? k : ((k % 2) + 10 * int_to_int(k / 2)));
}

Reason: the binary representation is stored as an integer. That is quite limited. Imagine converting a decimal to binary:

 dec 255  -> hex 0xFF  -> bin 0b1111_1111
 dec 1023 -> hex 0x3FF -> bin 0b11_1111_1111

and you have to store this binary representation as it were a decimal number.

I think the solution from Andy Finkenstadt is the closest to what you need

unsigned int_to_int(unsigned int k) {
    char buffer[65]; // any number higher than sizeof(unsigned int)*bits_per_byte(8)
    return itoa( atoi(k, buffer, 2) );
}

but still this does not work for large numbers. No suprise, since you probably don't really need to convert the string back to decimal. It makes less sense. If you need a binary number usually you need for a text somewhere, so leave it in string format.

simply use itoa()

char buffer[65];
itoa(k, buffer, 2);

There is also:

info all-registers

Then you can get the register name you are interested in -- very useful for finding platform-specific registers (like NEON Q... on ARM).

If your class extends Serializable, you can write and read objects through a ByteArrayOutputStream, that's what I usually do.

Known ID

$(".container > #first");

or

$(".container").children("#first");

or since IDs should be unique within a single document:

$("#first");

The last one is of course the fastest.

Unknown ID

Since you're saying that you don't know their ID top couple of the upper selectors (where #first is written), can be changed to:

$(".container > div");
$(".container").children("div");

The last one (of the first three selectors) that only uses ID is of course not possible to be changed in this way.

If you also need to filter out only those child DIV elements that define ID attribute you'd write selectors down this way:

$(".container > div[id]");
$(".container").children("div[id]");

Attach click handler

Add the following code to attach click handler to any of your preferred selector:

// use selector of your choice and call 'click' on it
$(".container > div").click(function(){
    // if you need element's ID
    var divID = this.id;
    cache your element if you intend to use it multiple times
    var clickedDiv = $(this);
    // add CSS class to it
    clickedDiv.addClass("add-some-class");
    // do other stuff that needs to be done
});

CSS3 Selectors specification

I would also like to point you to CSS3 selector specification that jQuery uses. It will help you lots in the future because there may be some selectors you're not aware of at all and could make your life much much easier.

After your edited question

I'm not completey sure that I know what you're after even though you've written some pseudo code... Anyway. Some parts can still be answered:

$(".container > div[id]").each(function(){
    var context = $(this);
    // get menu parent element: Sub: Show Grid
    // maybe I'm not appending to the correct element here but you should know
    context.appendTo(context.parent().parent());
    context.text("Show #" + this.id);
    context.attr("href", "");
    context.click(function(evt){
        evt.preventDefault();
        $(this).toggleClass("showgrid");
    })
});

the last thee context usages could be combined into a single chained one:

context.text(...).attr(...).click(...);

Regarding DOM elements

You can always get the underlaying DOM element from the jQuery result set.

$(...).get(0)
// or
$(...)[0]

will get you the first DOM element from the jQuery result set. jQuery result is always a set of elements even though there's none in them or only one.

But when I used .each() function and provided an anonymous function that will be called on each element in the set, this keyword actually refers to the DOM element.

$(...).each(function(){
    var DOMelement = this;
    var jQueryElement = $(this);
    ...
});

I hope this clears some things for your.

I had the pleasure of creating an email for outlook 2010 based on sharepoint data. But when creating an outlook email, outlook in its wisdom reduces the image width and height to cm. Interestingly using the width and height kicks in correctly when you forward the email but not when you open it.

Hack Fix:

I had an image [720px X 150px] which should be [19.05cm X 3.98cm]. BUT outlook set the image width and height to [15.24cm X 3.18cm]. Clearly this is a problem.

The hack I used was setting the html image tag as follows:

<img src="...." style="width:720px; heigh:150px" width="900" height="187.5" />

Why that width and height?

Well it is the ratio (25% increase) between

• what outlook was saying and
• what it should be by adding 25% of the current size; which is (720 X 1.25 = 900) and (150 X 1.25 = 187.5).

Its not pretty but it works.

names = [];
$('input[name=text], textarea').each(
    function(index){  
        var input = $(this);
        names.push( input.attr('name') );
        //input.attr('id');
    }
);

it select all textboxes and textarea in your DOM, where $.each function iterates to provide name of ecah element.

Replace the earlier function with the provided one. The simplest solution is:

def __unicode__(self):

    return unicode(self.nom_du_site)

Opens a new window with the url you supplied :)

<button class="button" onClick="window.open('http://www.example.com');">
     <span class="icon">Open</span>
</button>

hope that helps :)

Back in 2010, I suggested to use Joda-Time for that.

Note that Joda-Time is now in maintenance mode. Since 1.8 (2014), you should use java.time.

Add one day at a time until reaching the end date:

int days = Days.daysBetween(startDate, endDate).getDays();
List<LocalDate> dates = new ArrayList<LocalDate>(days);  // Set initial capacity to `days`.
for (int i=0; i < days; i++) {
    LocalDate d = startDate.withFieldAdded(DurationFieldType.days(), i);
    dates.add(d);
}

It wouldn't be too hard to implement your own iterator to do this as well, that would be even nicer.

Eclipse doesn't pull the tooltips from the javadoc location. It only uses the javadoc location to prepend to the link if you say open in browser, you need to download and attach the source for the JDK in order to get the tooltips. For all the JARs under the JRE you should have the following for the javadoc location: http://java.sun.com/javase/6/docs/api/. For resources.jar, rt.jar, jsse.jar, jce.jar and charsets.jar you should attach the source available here.

I am a Python user who sometimes copy and paste into Vim. (I switched from Mac to Windows WSL) and this was one of the glitches that bothered me.

If you touch a script.py and then vi script.py, Vi will detect it is a Python script and tried to be helpful, autoindent, paste with extra indents, etc. This won't happen if you don't tell it is a Python script.

However, if that is already happening to you, the default autoindent could be a nightmare when you paste already fully indented code (see the tilted ladder shape below).

I tried three options and here are the results

set paste        # works perfect 
set noai         # still introduced extra whitespace
set noautoindent # still introduced extra whitespace

import random
rgb_full="(" + str(random.randint(1,256))  + "," + str(random.randint(1,256))  + "," + str(random.randint(1,256))  + ")"

A Mocha test case example:

describe('Check version of node', function () {
    it('Should test version assert', async function () {

            var version = process.version;
            var check = parseFloat(version.substr(1,version.length)) > 12.0;
            console.log("version: "+version);
            console.log("check: " +check);         
            assert.equal(check, true);
    });});

You also will have to catch or throw the IOException. See below. Not always the best way, but it will get you a result:

public class details {
    public static void main( String[] args) throws IOException {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

Forget it, this is not doable.

No matter what you try it will not work. All a user needs to do to discover your code and it's location is to look in the net tab in firebug or use fiddler to see what requests are being made.

One way is to run the program in a subshell, and communicate with the subshell through a named pipe with the read command. This way you can check the exit status of the process being run and communicate this back through the pipe.

Here's an example of timing out the yes command after 3 seconds. It gets the PID of the process using pgrep (possibly only works on Linux). There is also some problem with using a pipe in that a process opening a pipe for read will hang until it is also opened for write, and vice versa. So to prevent the read command hanging, I've "wedged" open the pipe for read with a background subshell. (Another way to prevent a freeze to open the pipe read-write, i.e. read -t 5 <>finished.pipe - however, that also may not work except with Linux.)

rm -f finished.pipe
mkfifo finished.pipe

{ yes >/dev/null; echo finished >finished.pipe ; } &
SUBSHELL=$!

# Get command PID
while : ; do
    PID=$( pgrep -P $SUBSHELL yes )
    test "$PID" = "" || break
    sleep 1
done

# Open pipe for writing
{ exec 4>finished.pipe ; while : ; do sleep 1000; done } &  

read -t 3 FINISHED <finished.pipe

if [ "$FINISHED" = finished ] ; then
  echo 'Subprocess finished'
else
  echo 'Subprocess timed out'
  kill $PID
fi

rm finished.pipe

Edit %APPDATA%\Sublime Text 2\Python\Python.sublime-build

Change content to:

{
    "cmd": ["C:\\python27\\python.exe", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

change the "c:\python27" part to any version of python you have in your system.

Try this in MVC 4.0

@Html.TextBoxFor(m => m.YourDate, "{0:dd/MM/yyyy}", new { @class = "datefield form-control", @placeholder = "Enter start date..." })

There is timeline.sty floating around.

The syntax is simpler than using tikz:

%%% In LaTeX:
%%% \begin{timeline}{length}(start,stop)
%%%   .
%%%   .
%%%   .
%%% \end{timeline}
%%%
%%% in plain TeX
%%% \timeline{length}(start,stop)
%%%   .
%%%   .
%%%   .
%%% \endtimeline
%%% in between the two, we may have:
%%% \item{date}{description}
%%% \item[sortkey]{date}{description}
%%% \optrule
%%%
%%% the options to timeline are:
%%%      length The amount of vertical space that the timeline should
%%%                use.
%%%      (start,stop) indicate the range of the timeline. All dates or
%%%                sortkeys should lie in the range [start,stop]
%%%
%%% \item without the sort key expects date to be a number (such as a
%%%      year).
%%% \item with the sort key expects the sort key to be a number; date
%%%      can be anything. This can be used for log scale time lines
%%%      or dates that include months or days.
%%% putting \optrule inside of the timeline environment will cause a
%%%      vertical rule to be drawn down the center of the timeline.

I've used python's datetime.data.toordinal to convert dates to 'sort keys' in the context of the package.

All radio buttons must have the same name attribute added.

Put the word.txt directly as a child of the project root folder and a peer of src

Project_Root
    src
    word.txt

Disclaimer: I'd like to explain why this works for this particular case and why it may not work for others.

Why it works:

When you use File or any of the other FileXxx variants, you are looking for a file on the file system relative to the "working directory". The working directory, can be described as this:

When you run from the command line

C:\EclipseWorkspace\ProjectRoot\bin > java com.mypackage.Hangman1

the working directory is C:\EclipseWorkspace\ProjectRoot\bin. With your IDE (at least all the ones I've worked with), the working directory is the ProjectRoot. So when the file is in the ProjectRoot, then using just the file name as the relative path is valid, because it is at the root of the working directory.

Similarly, if this was your project structure ProjectRoot\src\word.txt, then the path "src/word.txt" would be valid.

Why it May not Work

For one, the working directory could always change. For instance, running the code from the command line like in the example above, the working directory is the bin. So in this case it will fail, as there is not bin\word.txt

Secondly, if you were to export this project into a jar, and the file was configured to be included in the jar, it would also fail, as the path will no longer be valid either.

That being said, you need to determine if the file is to be an embedded-resource (or just "resource" - terms which sometimes I'll use interchangeably). If so, then you will want to build the file into the classpath, and access it via an URL. First thing you would need to do (in this particular) case is make sure that the file get built into the classpath. With the file in the project root, you must configure the build to include the file. But if you put the file in the src or in some directory below, then the default build should put it into the class path.

You can access classpath resource in a number of ways. You can make use of the Class class, which has getResourceXxx method, from which you use to obtain classpath resources.

For example, if you changed your project structure to ProjectRoot\src\resources\word.txt, you could use this:

InputStream is = Hangman1.class.getResourceAsStream("/resources/word.txt");
BufferedReader reader = new BufferedReader(new InputStreamReader(is));

getResourceAsStream returns an InputStream, but obtains an URL under the hood. Alternatively, you could get an URL if that's what you need. getResource() will return an URL

For Maven users, where the directory structure is like src/main/resources, the contents of the resources folder is put at the root of the classpath. So if you have a file in there, then you would only use getResourceAsStream("/thefile.txt")

filter_by uses keyword arguments, whereas filter allows pythonic filtering arguments like filter(User.name=="john")

My understanding of SQLiteDatabase APIs is that in case you have a multi threaded application, you cannot afford to have more than a 1 SQLiteDatabase object pointing to a single database.

The object definitely can be created but the inserts/updates fail if different threads/processes (too) start using different SQLiteDatabase objects (like how we use in JDBC Connection).

The only solution here is to stick with 1 SQLiteDatabase objects and whenever a startTransaction() is used in more than 1 thread, Android manages the locking across different threads and allows only 1 thread at a time to have exclusive update access.

Also you can do "Reads" from the database and use the same SQLiteDatabase object in a different thread (while another thread writes) and there would never be database corruption i.e "read thread" wouldn't read the data from the database till the "write thread" commits the data although both use the same SQLiteDatabase object.

This is different from how connection object is in JDBC where if you pass around (use the same) the connection object between read and write threads then we would likely be printing uncommitted data too.

In my enterprise application, I try to use conditional checks so that the UI Thread never have to wait, while the BG thread holds the SQLiteDatabase object (exclusively). I try to predict UI Actions and defer BG thread from running for 'x' seconds. Also one can maintain PriorityQueue to manage handing out SQLiteDatabase Connection objects so that the UI Thread gets it first.

Please try this,

SELECT 
c.Id,
c.name,
(SELECT pi.price FROM purchase pi WHERE pi.Id = MAX(p.Id)) AS [LastPurchasePrice]
FROM customer c INNER JOIN purchase p 
ON c.Id = p.customerId 
GROUP BY c.Id,c.name;

You can get HTML5 tags working in IE8 by including this JavaScript in the head.

<script type="text/javascript">
 document.createElement('header');
 document.createElement('nav');
 document.createElement('menu');
 document.createElement('section');
 document.createElement('article');
 document.createElement('aside');
 document.createElement('footer');
</script>

matrix.size according to the numpy docs returns the Number of elements in the array. Hope that helps.

if ( !driver.findElement(By.id("idOfTheElement")).isSelected() )
{
     driver.findElement(By.id("idOfTheElement")).click();
}

When docker kill CONTAINER_ID does not work and docker stop -t 1 CONTAINER_ID also does not work, you can try to delete the container:

docker container rm CONTAINER_ID

I had a similar issue today where containers were in a continuous restart loop.

The issue in my case was related to me being a poor engineer.

Anyway, I fixed the issue by deleting the container, fixing my code, and then rebuilding and running the container.

Hope that this helps anyone stuck with this issue in future

In my case I was getting latin cross sign instead of nbsp, even that a page was correctly encoded into the UTF-8. Nothing of above helped in resolving the issue and I tried all.

In the end changing font for IE (with browser specific css) helped, I was using Helvetica-Nue as a body font changing to the Arial resolved the issue .

Well, the reason to use the pointer would be exactly the same that the reason to use pointers in C allocated with malloc: if you want your object to live longer than your variable!

It is even highly recommended to NOT use the new operator if you can avoid it. Especially if you use exceptions. In general it is much safer to let the compiler free your objects.

Just simply add or die(mysqli_error($db)); at the end of your query, this will print the mysqli error.

 mysqli_query($db,"INSERT INTO stockdetails (`itemdescription`,`itemnumber`,`sellerid`,`purchasedate`,`otherinfo`,`numberofitems`,`isitdelivered`,`price`) VALUES ('$itemdescription','$itemnumber','$sellerid','$purchasedate','$otherinfo','$numberofitems','$numberofitemsused','$isitdelivered','$price')") or die(mysqli_error($db));

As a side note I'd say you are at risk of mysql injection, check here How can I prevent SQL injection in PHP?. You should really use prepared statements to avoid any risk.

If you are using Angular 2 (apparently it also works for Angular 4 too), you can use the following to round to two decimal places{{ exampleNumber | number : '1.2-2' }}, as in:

<ion-input value="{{ exampleNumber | number : '1.2-2' }}"></ion-input>

BREAKDOWN

'1.2-2' means {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}:

• A minimum of 1 digit will be shown before decimal point
• It will show at least 2 digits after decimal point
• But not more than 2 digits

You should check with SMTP.

That means you have to connect to that email's SMTP server.

After connecting to the SMTP server you should send these commands:

HELO somehostname.com
MAIL FROM: <[email protected]>
RCPT TO: <[email protected]>

If you get "<[email protected]> Relay access denied" that means this email is Invalid.

There is a simple PHP class. You can use it:

When executable path has whitespace in system, call

#include<iostream>
using namespace std;
int main()
{

    system("pause");
return 0;
}

SELECT COLUMN_NAME, TABLE_NAME,table_schema
FROM INFORMATION_SCHEMA.COLUMNS;

Define a function mapEntries.

mapEntries takes a callback function that is called on each entry in the object with the parameters value, key and object. It should return the a new value.

mapEntries should return a new object with the new values returned from the callback.

Object.defineProperty(Object.prototype, 'mapEntries', {
  enumerable: false,
  value: function (mapEntriesCallback) {
    return Object.fromEntries(
      Object.entries(this).map(
        ([key, value]) => [key, mapEntriesCallback(value, key, this)]
      )
    )
  }
})


// Usage example:

var object = {a: 1, b: 2, c: 3}
var newObject = object.mapEntries(value => value * value)
console.log(newObject)
//> {a: 1, b: 4, c: 9}

Edit: A previous version didn't specify that this is not an enumerable property

printf is great, but people forget about it.

$ for num in 1 10 100 1000 10000 100000 1000000; do printf "%10s %s\n" $num "foobar"; done
         1 foobar
        10 foobar
       100 foobar
      1000 foobar
     10000 foobar
    100000 foobar
   1000000 foobar

$ for((i=0;i<array_size;i++));
do
    printf "%10s %10d %10s" stringarray[$i] numberarray[$i] anotherfieldarray[%i]
done

Notice I used %10s for strings. %s is the important part. It tells it to use a string. The 10 in the middle says how many columns it is to be. %d is for numerics (digits).

man 1 printf for more info.

Now you need to add .dropdown-menu-right to the existing .dropdown-menu element. pull-right is not supported anymore.

More info here http://getbootstrap.com/components/#btn-dropdowns

suppose the multiSelect is the Multiple-Select-Element, just use its selectedOptions Property:

//show all selected options in the console:

for ( var i = 0; i < multiSelect.selectedOptions.length; i++) {
  console.log( multiSelect.selectedOptions[i].value);
}

Taking reference of ThiefMaster? sometimes we get an error with value given as '\n' or null and perform for that required to handle ValueError:

Handling the exception is the way to go

try:
    gotdata = dlist[1]
except (IndexError, ValueError):
    gotdata = 'null'

as i know there are 4 ways to do that.

var style= document.createElement("style");
(document.head || document.documentElement).appendChild(style);
var rule=':visited {    color: rgb(233, 106, 106) !important;}';

//no 1
style.innerHTML = rule;
//no 2
style.appendChild(document.createTextNode(rule));

//no 3 limited with one group
style.sheet.insertRule(rule);
//no 4 limited too
document.styleSheets[0].insertRule('strong { color: red; }');

//addon
style.sheet.cssRules //list all style
stylesheet.deleteRule(0)  //delete first rule

To go into why size_t needed to exist and how we got here:

In pragmatic terms, size_t and ptrdiff_t are guaranteed to be 64 bits wide on a 64-bit implementation, 32 bits wide on a 32-bit implementation, and so on. They could not force any existing type to mean that, on every compiler, without breaking legacy code.

A size_t or ptrdiff_t is not necessarily the same as an intptr_t or uintptr_t. They were different on certain architectures that were still in use when size_t and ptrdiff_t were added to the Standard in the late ’80s, and becoming obsolete when C99 added many new types but not gone yet (such as 16-bit Windows). The x86 in 16-bit protected mode had a segmented memory where the largest possible array or structure could be only 65,536 bytes in size, but a far pointer needed to be 32 bits wide, wider than the registers. On those, intptr_t would have been 32 bits wide but size_t and ptrdiff_t could be 16 bits wide and fit in a register. And who knew what kind of operating system might be written in the future? In theory, the i386 architecture offers a 32-bit segmentation model with 48-bit pointers that no operating system has ever actually used.

The type of a memory offset could not be long because far too much legacy code assumes that long is exactly 32 bits wide. This assumption was even built into the UNIX and Windows APIs. Unfortunately, a lot of other legacy code also assumed that a long is wide enough to hold a pointer, a file offset, the number of seconds that have elapsed since 1970, and so on. POSIX now provides a standardized way to force the latter assumption to be true instead of the former, but neither is a portable assumption to make.

It couldn’t be int because only a tiny handful of compilers in the ’90s made int 64 bits wide. Then they really got weird by keeping long 32 bits wide. The next revision of the Standard declared it illegal for int to be wider than long, but int is still 32 bits wide on most 64-bit systems.

It couldn’t be long long int, which anyway was added later, since that was created to be at least 64 bits wide even on 32-bit systems.

So, a new type was needed. Even if it weren’t, all those other types meant something other than an offset within an array or object. And if there was one lesson from the fiasco of 32-to-64-bit migration, it was to be specific about what properties a type needed to have, and not use one that meant different things in different programs.

Might be a slightly different cause, but that second issue occurs for me in scala 2.9.0.1 on Win7 (x64), though scala-2.9.1.final has already resolved this issue mentioned here:

\Java\jdk1.6.0_25\bin\java.exe was unexpected at this time.

My %JAVA_HOME% set to a path like this: c:\program files(x86)\Java\jdk...

Note the space and the parentheses.

If you change line 24 in %SCALA_HOME%\bin\scala.bat from:

if exist "%JAVA_HOME%\bin\java.exe" set _JAVACMD=%JAVA_HOME%\bin\java.exe

to

if exist "%JAVA_HOME%\bin\java.exe" set "_JAVACMD=%JAVA_HOME%\bin\java.exe"

It works fine. Note the quotes around the set command parameters, this will properly enclose any spaces and 'special' characters (eg: spaces and parentheses) in the variable's value.

Hope this helps someone else searching for an answer.

I've bumped into this question because I actually wanted to define a default goal in pom.xml. You can define a default goal under build:

<build>
    <defaultGoal>install</defaultGoal>
...
</build>

After that change, you can then simply run mvn which will do exactly the same as mvn install.

Note: I don't favor this as a default approach. My use case was to define a profile that downloaded a previous version of that project from Artifactory and wanted to tie that profile to a given phase. For convenience, I can run mvn -Pdownload-jar -Dversion=0.0.9 and don't need to specify a goal/phase there. I think it's reasonable to define a defaultGoal in a profile which has a very specific function for a particular phase.

When you push a new branch the first time use: >git push -u origin

After that, you can just type a shorter command: >git push

The first-time -u option created a persistent upstream tracking branch with your local branch.

Expending on @spitfire109's fine answer, one could do something like this:

rootClassNames() {
  let names = ['my-default-class'];
  if (this.props.disabled) names.push('text-muted', 'other-class');

  return names.join(' ');
}

and then within the render function:

<div className={this.rootClassNames()}></div>

keeps the jsx short

itertools provides the chain function for that:

From http://docs.python.org/library/itertools.html#recipes:

def flatten(listOfLists):
    "Flatten one level of nesting"
    return chain.from_iterable(listOfLists)

Note that the result is an iterable, so you may need list(flatten(...)).

tldr; both HTTP/1.1 and HTTP/2 headers are case-insensitive.

According to RFC 7230 (HTTP/1.1):

Each header field consists of a case-insensitive field name followed by a colon (":"), optional leading whitespace, the field value, and optional trailing whitespace.

https://tools.ietf.org/html/rfc7230#section-3.2

Also, RFC 7540 (HTTP/2):

Just as in HTTP/1.x, header field names are strings of ASCII
characters that are compared in a case-insensitive fashion.

https://tools.ietf.org/html/rfc7540#section-8.1.2

None of the above solutions were suitable for my scenario, handling .Navigated and .FileDownload events seemed like a good fit but accessing the WebBrowser.Document property threw an UnauthorizedAccessException which is caused by cross frame scripting security (our web content contains frames - all on the same domain/address but frames have their own security holes that are being blocked).

You can use various css-resets as you need, normal and use in css

 html

To use the window object is not a good idea. As I see in comments,

'use strict';

function showMessage() {
    window.say_hello = 'hello!';
}

console.log(say_hello);

This will throw an error to use the say_hello variable we need to first call the showMessage function.

How to set redis password ?

step 1. stop redis server using below command /etc/init.d/redis-server stop

step 2.enter command : sudo nano /etc/redis/redis.conf

step 3.find # requirepass foobared word and remove # and change foobared to YOUR PASSWORD

ex. requirepass root

If you're needing to test remote urls in an input field, you can try testing a simple regex with the types that you're interested in.

$input_field = $('.js-input-field-class');

if ( !(/\.(gif|jpg|jpeg|tiff|png)$/i).test( $input_field.val() )) {
  $('.error-message').text('This URL is not a valid image type. Please use a url with the known image types gif, jpg, jpeg, tiff or png.');
  return false;
}

This will capture anything ending in .gif, .jpg, .jpeg, .tiff or .png

I should note that some popular sites like Twitter append a size attribute to the end of their images. For instance, the following would fail this test even though it's a valid image type:

https://pbs.twimg.com/media/BrTuXT5CUAAtkZM.jpg:large

Because of that, this isn't a perfect solution. But it will get you to about 90% of the way.

I wanted my logging information to be sent to stdout because it's easy to tell Amazon's Container service (ECS) to collect stdout and send it to CloudWatch Logs. So to get this working, I added a new stdout entry to my config/logging.php file like so:

    'stdout' => [
        'driver' => 'monolog',
        'handler' => StreamHandler::class,
        'with' => [
            'stream' => 'php://stdout',
        ],
        'level' => 'info',
    ],

Then I simply added 'stdout' as one of the channels in the stack log channel:

    'default' => env('LOG_CHANNEL', 'stack'),

    'stack' => [
        'driver' => 'stack',
        'channels' => ['stdout', 'daily'],
    ],

This way, I still get logs in a file for local development (or even on the instance if you can access it), but more importantly they get sent to the stdout which is saved in CloudWatch Logs.

this might be a solution, i have done something similar but this one does not seem to work for example if the necessary function requires administrator privileges it should ask you to restart it as admin.

@echo off
mkdir C:\Users\cmdfolder

if echo=="Access is denied." (goto :1A) else (goto :A4)

:A1
cls 
color 0d
echo restart this program as administator

:A4
pause

public OnClickListener moreListener = new OnClickListener() {

    @Override
      public void onClick(View v) {
          adapter.add("aaaa")
      }
}

A moving average is a convolution, and numpy will be faster than most pure python operations. This will give you the 10 point moving average.

import numpy as np
smoothed = np.convolve(data, np.ones(10)/10)

I would also strongly suggest using the great pandas package if you are working with timeseries data. There are some nice moving average operations built in.

Should work.

Here's a working example:

http://jsfiddle.net/rhpNc/

Excerpt:

function loadIframe(iframeName, url) {
    var $iframe = $('#' + iframeName);
    if ($iframe.length) {
        $iframe.attr('src',url);
        return false;
    }
    return true;
}

In case you have trouble building boost or prefer not to do that, an alternative is to download the lib files from SourceForge. The link will take you to a folder of zipped lib and dll files for version 1.51. But, you should be able to edit the link to specify the version of choice. Apparently the installer from BoostPro has some issues.

Call the code with two float values, the code works in any range.

float rand_FloatRange(float a, float b)
{
    return ((b - a) * ((float)rand() / RAND_MAX)) + a;
}

I think it's worth mentioning how the Underscore's _.each() works internally. The _.each(list, iteratee) checks if the passed list is an array object, or an object.

In the case that the list is an array, iteratee arguments will be a list element and index as in the following example:

var a = ['I', 'like', 'pancakes', 'a', 'lot', '.'];
_.each( a, function(v, k) { console.log( k + " " + v); });

0 I
1 like
2 pancakes
3 a
4 lot
5 .

On the other hand, if the list argument is an object the iteratee will take a list element and a key:

var o = {name: 'mike', lastname: 'doe', age: 21};
_.each( o, function(v, k) { console.log( k + " " + v); });

name mike
lastname doe
age 21

For reference this is the _.each() code from Underscore.js 1.8.3

_.each = _.forEach = function(obj, iteratee, context) {
   iteratee = optimizeCb(iteratee, context);
   var i, length;
   if (isArrayLike(obj)) {
      for (i = 0, length = obj.length; i < length; i++) {
         iteratee(obj[i], i, obj);
      }
   } else {
      var keys = _.keys(obj);
      for (i = 0, length = keys.length; i < length; i++) {
         iteratee(obj[keys[i]], keys[i], obj);
      }
   }
   return obj;
};

Edit

As WhatsApp put some effort into improving their encryption system, getting the data is not that easy anymore. With newer versions of WhatsApp it is no longer possible to use adb backup. Apps can deny backups and the WhatsApp client does that. If you happen to have a rooted phone, you can use a root shell to get the unencrypted database file.

If you do not have root, you can still decrypt the data if you have an old WhatsApp APK. Find a version that still allows backups. Then you can make a backup of the app's data folder, which will contain an encryption key named, well, key.

Now you'll need the encrypted database. Use a file explorer of your choice or, if you like the command line more, use adb:

adb pull /sdcard/WhatsApp/Databases/msgstore.db.crypt12

Using the two files, you could now use https://gitlab.com/digitalinternals/whatsapp-crypt12 to get the plain text database. It is no longer possible to use Linux board tools like openssl because WhatsApp seems to use a modified version of the Spongy Castle API for cryptography that openssl does not understand.

Original Answer (only for the old crypt7)

As whatsapp is now using the crypt7 format, it is not that easy to get and decrypt the database anymore. There is a working approach using ADB and USB debugging.

You can either get the encryption keys via ADB and decrypt the message database stored on /sdcard, or you just get the plain version of the database via ADB backup, what seems to be the easier option.

To get the database, do the following:

Connect your Android phone to your computer. Now run

adb backup -f whatsapp_backup.ab -noapk com.whatsapp

to backup all files WhatsApp has created in its private folder.
You will get a zlib compressed file using tar format with some ADB headers. We need to get rid of those headers first as they confuse the decompression command:

dd if=whatsapp_backup.ab ibs=1 skip=24 of=whatsapp_backup.ab.nohdr

The file can now be decompressed:

cat whatsapp_backup.ab.nohdr | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" 1> whatsapp_backup.tar

This command runs Python and decompresses the file using zlib to whatsapp_backup.tar
Now we can unTAR the file:

tar xf whatsapp_backup.tar

The archive is now extracted to your current working directory and you can find the databases (msgstore.db and wa.db) in apps/com.whatsapp/db/

FileNameOnly = Dir(.SelectedItems(1))

I disagree with this kind of path

GET /companies/{companyId}/departments

If you want to get departments, I think it's better to use a /departments resource

GET /departments?companyId=123

I suppose you have a companies table and a departments table then classes to map them in the programming language you use. I also assume that departments could be attached to other entities than companies, so a /departments resource is straightforward, it's convenient to have resources mapped to tables and also you don't need as many endpoints since you can reuse

GET /departments?companyId=123

for any kind of search, for instance

GET /departments?name=xxx
GET /departments?companyId=123&name=xxx
etc.

If you want to create a department, the

POST /departments

resource should be used and the request body should contain the company ID (if the department can be linked to only one company).

Page content can be displayed easily and perfectly this way:

<?php if(have_posts()) : ?>
    <?php while(have_posts())  : the_post(); ?>
      <h2><?php the_title(); ?></h2>                        
      <?php the_content(); ?>          
      <?php comments_template( '', true ); ?> 
    <?php endwhile; ?>                   
      <?php else : ?>                       
        <h3><?php _e('404 Error&#58; Not Found'); ?></h3>
<?php endif; ?>         

Note:

In terms of displaying content - i) comments_template() function is an optional use if you need to enable commenting with different functionality.

ii) _e() function is also optional but more meaningful & effective than just showing text through <p>. while preferred stylized 404.php can be created to be redirected.

You should be able to see it in the Services panel. Look for a servicename like Sql Server (MSSQLSERVER). The name in the parentheses is your instance name.

perl -i    -nle'/regexp/||print' file1 file2 file3
perl -i.bk -nle'/regexp/||print' file1 file2 file3

The first command edits the file(s) inplace (-i).

The second command does the same thing but keeps a copy or backup of the original file(s) by adding .bk to the file names (.bk can be changed to anything).

It might be a wrong path. Ensure in your main app file you have:

app.use(express.static(path.join(__dirname,"public")));

Example link to your css as:

<link href="/css/clean-blog.min.css" rel="stylesheet">

similar for link to js files:

<script src="/js/clean-blog.min.js"></script>

Because they have different meanings. The @Transient annotation tells the JPA provider to not persist any (non-transient) attribute. The other tells the serialization framework to not serialize an attribute. You might want to have a @Transient property and still serialize it.

this will subtract ten days of the current date (before Java 8):

int x = -10;
Calendar cal = GregorianCalendar.getInstance();
cal.add( Calendar.DAY_OF_YEAR, x);
Date tenDaysAgo = cal.getTime();

If you're using Java 8 you can make use of the new Date & Time API (http://www.oracle.com/technetwork/articles/java/jf14-date-time-2125367.html):

LocalDate tenDaysAgo = LocalDate.now().minusDays(10);

For converting the new to the old types and vice versa see: Converting between java.time.LocalDateTime and java.util.Date

I just tried this, and this could be a jQuery version-specific error, but

$("meta[property=twitter:image]").attr("content");

resulted in the following syntax error for me:

Error: Syntax error, unrecognized expression: meta[property=twitter:image]

Apparently it doesn't like the colon. I was able to fix it by using double and single quotes like this:

$("meta[property='twitter:image']").attr("content");

(jQuery version 1.8.3 -- sorry, I would have made this a comment to @Danilo, but it won't let me comment yet)

Why bother to add indices first and then reverse them? Enumerate() function is just a special case of zip() function usage. Let's use it in appropiate way:

my_indexed_list = zip(my_list, range(len(my_list)))

min_value, min_index = min(my_indexed_list)
max_value, max_index = max(my_indexed_list)

From JLS http://docs.oracle.com/javase/specs/jls/se5.0/html/arrays.html#10.2

Here are examples of declarations of array variables that do not create arrays:

int[ ] ai;          // array of int
short[ ][ ] as;         // array of array of short
Object[ ]   ao,     // array of Object
        otherAo;    // array of Object
Collection<?>[ ] ca;        // array of Collection of unknown type
short       s,      // scalar short 
        aas[ ][ ];  // array of array of short

Here are some examples of declarations of array variables that create array objects:

Exception ae[ ] = new Exception[3]; 
Object aao[ ][ ] = new Exception[2][3];
int[ ] factorial = { 1, 1, 2, 6, 24, 120, 720, 5040 };
char ac[ ] = { 'n', 'o', 't', ' ', 'a', ' ',
                 'S', 't', 'r', 'i', 'n', 'g' }; 
String[ ] aas = { "array", "of", "String", };

The [ ] may appear as part of the type at the beginning of the declaration, or as part of the declarator for a particular variable, or both, as in this example:

byte[ ] rowvector, colvector, matrix[ ];

This declaration is equivalent to:

byte rowvector[ ], colvector[ ], matrix[ ][ ];

As far as I know, this is a work-in-progress. They want to do it, but it's not released yet. See 1377 (the "new" 495 that was mentioned by @Andy).

I ended up implementing the "generate .yml as part of CI" approach as proposed by @Thomas.

You can try this it may be help to you

$search_string = 'american golf News: Fowler beats stellar field in Abu Dhabi';
$html = file_get_contents(url of the site);
$dom = new DOMDocument;
$titalDom = new DOMDocument;
$tmpTitalDom = new DOMDocument;
libxml_use_internal_errors(true);
@$dom->loadHTML($html);
libxml_use_internal_errors(false);
$xpath = new DOMXPath($dom);
$videos = $xpath->query('//div[@class="primary-content"]');
foreach ($videos as $key => $video) {
$newdomaindom = new DOMDocument;    
$newnode = $newdomaindom->importNode($video, true);
$newdomaindom->appendChild($newnode);
@$titalDom->loadHTML($newdomaindom->saveHTML());
$xpath1 = new DOMXPath($titalDom);
$titles = $xpath1->query('//div[@class="listingcontainer"]/div[@class="list"]');
if(strcmp(preg_replace('!\s+!',' ',  $titles->item(0)->nodeValue),$search_string)){     
    $tmpNode = $tmpTitalDom->importNode($video, true);
    $tmpTitalDom->appendChild($tmpNode);
    break;
}
}
echo $tmpTitalDom->saveHTML();

Here is a bit more robust way of doing this, also handling the return values of enable()\disable() methods:

public static boolean setBluetooth(boolean enable) {
    BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
    boolean isEnabled = bluetoothAdapter.isEnabled();
    if (enable && !isEnabled) {
        return bluetoothAdapter.enable(); 
    }
    else if(!enable && isEnabled) {
        return bluetoothAdapter.disable();
    }
    // No need to change bluetooth state
    return true;
}

And add the following permissions into your manifest file:

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

But remember these important points:

This is an asynchronous call: it will return immediately, and clients should listen for ACTION_STATE_CHANGED to be notified of subsequent adapter state changes. If this call returns true, then the adapter state will immediately transition from STATE_OFF to STATE_TURNING_ON, and some time later transition to either STATE_OFF or STATE_ON. If this call returns false then there was an immediate problem that will prevent the adapter from being turned on - such as Airplane mode, or the adapter is already turned on.

UPDATE:

Ok, so how to implement bluetooth listener?:

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        final String action = intent.getAction();

        if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED)) {
            final int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE,
                                                 BluetoothAdapter.ERROR);
            switch (state) {
            case BluetoothAdapter.STATE_OFF:
                // Bluetooth has been turned off;
                break;
            case BluetoothAdapter.STATE_TURNING_OFF:
                // Bluetooth is turning off;
                break;
            case BluetoothAdapter.STATE_ON:
                // Bluetooth is on
                break;
            case BluetoothAdapter.STATE_TURNING_ON:
                // Bluetooth is turning on
                break;
            }
        }
    }
};

And how to register/unregister the receiver? (In your Activity class)

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // ...

    // Register for broadcasts on BluetoothAdapter state change
    IntentFilter filter = new IntentFilter(BluetoothAdapter.ACTION_STATE_CHANGED);
    registerReceiver(mReceiver, filter);
}

@Override
public void onStop() {
    super.onStop();

     // ...

    // Unregister broadcast listeners
    unregisterReceiver(mReceiver);
}

Here's a function I wrote another application. Feel free to reuse:

function writeCookie (key, value, days) {
    var date = new Date();

    // Default at 365 days.
    days = days || 365;

    // Get unix milliseconds at current time plus number of days
    date.setTime(+ date + (days * 86400000)); //24 * 60 * 60 * 1000

    window.document.cookie = key + "=" + value + "; expires=" + date.toGMTString() + "; path=/";

    return value;
};

If you have a return value you need to send to the UI you can use the generic version like this:

This is being called from an MVVM ViewModel in my case.

var updateManifest = Task<ShippingManifest>.Run(() =>
    {
        Thread.Sleep(5000);  // prove it's really working!

        // GenerateManifest calls service and returns 'ShippingManifest' object 
        return GenerateManifest();  
    })

    .ContinueWith(manifest =>
    {
        // MVVM property
        this.ShippingManifest = manifest.Result;

        // or if you are not using MVVM...
        // txtShippingManifest.Text = manifest.Result.ToString();    

        System.Diagnostics.Debug.WriteLine("UI manifest updated - " + DateTime.Now);

    }, TaskScheduler.FromCurrentSynchronizationContext());

Process QProc = new Process();
QProc.StartInfo.FileName = "cmd";
QProc.StartInfo.Arguments ="/c InstallUtil "+ "\""+ filefullPath +"\"";
QProc.StartInfo.WorkingDirectory = Environment.GetEnvironmentVariable("windir") + @"\Microsoft.NET\Framework\v2.0.50727\";
QProc.StartInfo.UseShellExecute = false;
// QProc.StartInfo.CreateNoWindow = true;
QProc.StartInfo.RedirectStandardOutput = true;
QProc.Start();
// QProc.WaitForExit();
QProc.Close();

Well, I used curl in PHP to circumvent this. I have a webservice running in port 82.

<?php

$curl = curl_init();
$timeout = 30;
$ret = "";
$url="http://localhost:82/put_val?val=".$_GET["val"];
curl_setopt ($curl, CURLOPT_URL, $url);
curl_setopt ($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($curl, CURLOPT_MAXREDIRS, 20);
curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5");
curl_setopt ($curl, CURLOPT_CONNECTTIMEOUT, $timeout);
$text = curl_exec($curl);
echo $text;

?>

Here is the javascript that makes the call to the PHP file

function getdata(obj1, obj2) {

    var xmlhttp;

    if (window.XMLHttpRequest)
            xmlhttp=new XMLHttpRequest();
    else
            xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

    xmlhttp.onreadystatechange=function()
    {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
                document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
        }
    }
    xmlhttp.open("GET","phpURLFile.php?eqp="+obj1+"&val="+obj2,true);
    xmlhttp.send();
}

My HTML runs on WAMP in port 80. So there we go, same origin policy has been circumvented :-)

        $ipaddress = 'UNKNOWN';

   return $ipaddress;
} 

Here is one way to do this:

df = df[df.columns.drop(list(df.filter(regex='Test')))]

    @WebFilter(urlPatterns="/*")
    public class XSSFilter implements Filter {

        private static final org.apache.log4j.Logger LOGGER = LogManager.getLogger(XSSFilter.class);

        @Override
        public void init(FilterConfig filterConfig) throws ServletException {
            LOGGER.info("Initiating XSSFilter... ");

        }

        @Override
        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
                throws IOException, ServletException {
            HttpServletRequest req = (HttpServletRequest) request;
            HttpRequestWrapper requestWrapper = new HttpRequestWrapper(req);
            chain.doFilter(requestWrapper, response);
        }

        @Override
        public void destroy() {
            LOGGER.info("Destroying XSSFilter... ");
        }

    }

You need to implement Filter and need to be annotated with @WebFilter(urlPatterns="/*")

And in Application or Configuration class you need to add @ServletComponentScan By this it your filter will get registered.
