If all you need as a way to parse a dynamic string and load components by their selectors, you may also find the ngx-dynamic-hooks library useful. I initially created this as part of a personal project but didn't see anything like it around, so I polished it up a bit and made it public.

Some tidbids:

• You can load any components into a dynamic string by their selector (or any other pattern of your choice!)
• Inputs and outputs can be se just like in a normal template
• Components can be nested without restrictions
• You can pass live data from the parent component into the dynamically loaded components (and even use it to bind inputs/outputs)
• You can control which components can load in each outlet and even which inputs/outputs you can give them
• The library uses Angular's built-in DOMSanitizer to be safe to use even with potentially unsafe input.

Notably, it does not rely on a runtime-compiler like some of the other responses here. Because of that, you can't use template syntax. On the flipside, this means it works in both JiT and AoT-modes as well as both Ivy and the old template engine, as well as being much more secure to use in general.

See it in action in this Stackblitz.

In my case, I upgraded node.js version to latest (version 12.8.0) and it worked like a charm.

Seems related to https://groups.google.com/forum/#!msg/google-caja-discuss/ite6K5c8mqs/Ayqw72XJ9G8J.

The so-called "Rosetta Flash" vulnerability is that allowing arbitrary yet identifier-like text at the beginning of a JSONP response is sufficient for it to be interpreted as a Flash file executing in that origin. See for more information: http://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/

JSONP responses from the proxy servlet now: * are prefixed with "/**/", which still allows them to execute as JSONP but removes requester control over the first bytes of the response. * have the response header Content-Disposition: attachment.

Yes, using g++ command worked for me:

g++ my_source_code.cpp

Try this: http://jsbeautifier.org/

I tested with your code and worked as good as possible. =D

See this table.

A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.

A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.

This worked for me in IE 11:

<meta http-equiv="x-ua-compatible" content="IE=edge; charset=UTF-8">

try this:

$('div[id^="player_"]')

I got this issue trying some old format code in Swift3,

let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.respond))

changing the action:"respond:" to action: #selector(self.respond) fixed the issue for me.

Swift

self.dismissViewControllerAnimated(true, completion: nil)

If you want to get a class name from inside a class method, class.name or self.class.name won't work. These will just output Class, since the class of a class is Class. Instead, you can just use name:

module Foo
  class Bar
    def self.say_name
      puts "I'm a #{name}!"
    end
  end
end

Foo::Bar.say_name

output:

I'm a Foo::Bar!

As this Spring's Jira ticket, it is an intentional design. But the following code works for me.

public static Map<String, Object> getAllKnownProperties(Environment env) {
    Map<String, Object> rtn = new HashMap<>();
    if (env instanceof ConfigurableEnvironment) {
        for (PropertySource<?> propertySource : ((ConfigurableEnvironment) env).getPropertySources()) {
            if (propertySource instanceof EnumerablePropertySource) {
                for (String key : ((EnumerablePropertySource) propertySource).getPropertyNames()) {
                    rtn.put(key, propertySource.getProperty(key));
                }
            }
        }
    }
    return rtn;
}

I opened monitor.bat in android-sdks\tools and started the device manager there and I was able to create the AVD.

Working on the same idea as above , but generalizing a bit . Since the backspace should work fine on the input elements , but should not work if the focus is a paragraph or something , since it is there where the page tends to go back to the previous page in history .

$('html').on('keydown' , function(event) {

        if(! $(event.target).is('input')) {
            console.log(event.which);
           //event.preventDefault();
           if(event.which == 8) {
            //  alert('backspace pressed');
            return false;
         }
        }
});

returning false => both event.preventDefault and event.stopPropagation are in effect .

Prior to the introduction of git push -u, there was no git push option to obtain what you desire. You had to add new configuration statements.

If you create a new branch using:

$ git checkout -b branchB
$ git push origin branchB:branchB

You can use the git config command to avoid editing directly the .git/config file.

$ git config branch.branchB.remote origin
$ git config branch.branchB.merge refs/heads/branchB

Or you can edit manually the .git/config file to had tracking information to this branch.

[branch "branchB"]
    remote = origin
    merge = refs/heads/branchB

One line solution (per se) for SQL Server 2008 or above:

DECLARE @DesiredLenght INT = 20;
SELECT 
    CONCAT(
        REPLICATE(
            '0',
            (@DesiredLenght-LEN([Column])) * (1+SIGN(@DesiredLenght-LEN([Column])) / 2) ),
        [Column])
FROM Table;

Multiplication by SIGN expression is equivalent to MAX(0, @DesiredLenght-LEN([Column])). The problem is that MAX() accepts only one argument...

This is probably slower than what you want, but you can do:

>>> tostring = vectorize(lambda x: str(x))
>>> numpy.where(tostring(phis).astype('float64') != phis)
(array([], dtype=int64),)

It looks like it rounds off the values when it converts to str from float64, but this way you can customize the conversion however you like.

You may also want to look at rsync if you're doing a lot of files.

If you're going to making a lot of changes and want to keep your directories and files in sync, you may want to use a version control system like Subversion or Git. See http://xoa.petdance.com/How_to:_Keep_your_home_directory_in_Subversion

Linear Congruential Pseudo-random Number Generator

O(1) Memory

O(k) Operations

This problem can be solved with a simple Linear Congruential Generator. This requires constant memory overhead (8 integers) and at most 2*(sequence length) computations.

All other solutions use more memory and more compute! If you only need a few random sequences, this method will be significantly cheaper. For ranges of size N, if you want to generate on the order of N unique k-sequences or more, I recommend the accepted solution using the builtin methods random.sample(range(N),k) as this has been optimized in python for speed.

Code

# Return a randomized "range" using a Linear Congruential Generator
# to produce the number sequence. Parameters are the same as for 
# python builtin "range".
#   Memory  -- storage for 8 integers, regardless of parameters.
#   Compute -- at most 2*"maximum" steps required to generate sequence.
#
def random_range(start, stop=None, step=None):
    import random, math
    # Set a default values the same way "range" does.
    if (stop == None): start, stop = 0, start
    if (step == None): step = 1
    # Use a mapping to convert a standard range into the desired range.
    mapping = lambda i: (i*step) + start
    # Compute the number of numbers in this range.
    maximum = (stop - start) // step
    # Seed range with a random integer.
    value = random.randint(0,maximum)
    # 
    # Construct an offset, multiplier, and modulus for a linear
    # congruential generator. These generators are cyclic and
    # non-repeating when they maintain the properties:
    # 
    #   1) "modulus" and "offset" are relatively prime.
    #   2) ["multiplier" - 1] is divisible by all prime factors of "modulus".
    #   3) ["multiplier" - 1] is divisible by 4 if "modulus" is divisible by 4.
    # 
    offset = random.randint(0,maximum) * 2 + 1      # Pick a random odd-valued offset.
    multiplier = 4*(maximum//4) + 1                 # Pick a multiplier 1 greater than a multiple of 4.
    modulus = int(2**math.ceil(math.log2(maximum))) # Pick a modulus just big enough to generate all numbers (power of 2).
    # Track how many random numbers have been returned.
    found = 0
    while found < maximum:
        # If this is a valid value, yield it in generator fashion.
        if value < maximum:
            found += 1
            yield mapping(value)
        # Calculate the next value in the sequence.
        value = (value*multiplier + offset) % modulus

Usage

The usage of this function "random_range" is the same as for any generator (like "range"). An example:

# Show off random range.
print()
for v in range(3,6):
    v = 2**v
    l = list(random_range(v))
    print("Need",v,"found",len(set(l)),"(min,max)",(min(l),max(l)))
    print("",l)
    print()

Sample Results

Required 8 cycles to generate a sequence of 8 values.
Need 8 found 8 (min,max) (0, 7)
 [1, 0, 7, 6, 5, 4, 3, 2]

Required 16 cycles to generate a sequence of 9 values.
Need 9 found 9 (min,max) (0, 8)
 [3, 5, 8, 7, 2, 6, 0, 1, 4]

Required 16 cycles to generate a sequence of 16 values.
Need 16 found 16 (min,max) (0, 15)
 [5, 14, 11, 8, 3, 2, 13, 1, 0, 6, 9, 4, 7, 12, 10, 15]

Required 32 cycles to generate a sequence of 17 values.
Need 17 found 17 (min,max) (0, 16)
 [12, 6, 16, 15, 10, 3, 14, 5, 11, 13, 0, 1, 4, 8, 7, 2, ...]

Required 32 cycles to generate a sequence of 32 values.
Need 32 found 32 (min,max) (0, 31)
 [19, 15, 1, 6, 10, 7, 0, 28, 23, 24, 31, 17, 22, 20, 9, ...]

Required 64 cycles to generate a sequence of 33 values.
Need 33 found 33 (min,max) (0, 32)
 [11, 13, 0, 8, 2, 9, 27, 6, 29, 16, 15, 10, 3, 14, 5, 24, ...]

from pyspark.sql.types import IntegerType
data_df = data_df.withColumn("Plays", data_df["Plays"].cast(IntegerType()))
data_df = data_df.withColumn("drafts", data_df["drafts"].cast(IntegerType()))

You can run loop for each column but this is the simplest way to convert string column into integer.

The char already has an IsDigit(char c) which does this:

 public static bool IsDigit(char c)
    {
      if (!char.IsLatin1(c))
        return CharUnicodeInfo.GetUnicodeCategory(c) == UnicodeCategory.DecimalDigitNumber;
      if ((int) c >= 48)
        return (int) c <= 57;
      else
        return false;
    }

You can simply do this:

var theString = "839278";
bool digitsOnly = theString.All(char.IsDigit);

Since unpaidMembers is a dictionary it always returns two values when called with .items() - (key, value). You may want to keep your data as a list of tuples [(name, email, lastname), (name, email, lastname)..].

If the structs only contain primitives or if you are interested in strict equality then you can do something like this:

int my_struct_cmp(const struct my_struct * lhs, const struct my_struct * rhs)
{
    return memcmp(lhs, rsh, sizeof(struct my_struct));
}

However, if your structs contain pointers to other structs or unions then you will need to write a function that compares the primitives properly and make comparison calls against the other structures as appropriate.

Be aware, however, that you should have used memset(&a, sizeof(struct my_struct), 1) to zero out the memory range of the structures as part of your ADT initialization.

You put your template in the wrong place. From the Flask docs:

Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package: See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates

element.innerHTML = "" (or .textContent) is by far the fastest solution

Most of the answers here are based on flawed tests

For example: https://jsperf.com/innerhtml-vs-removechild/15
This test does not add new children to the element between each iteration. The first iteration will remove the element's contents, and every other iteration will then do nothing. In this case, while (box.lastChild) box.removeChild(box.lastChild) was faster because box.lastChild was null 99% of the time

Here is a proper test: https://jsperf.com/innerhtml-conspiracy

Finally, do not use node.parentNode.replaceChild(node.cloneNode(false), node). This will replace the node with a copy of itself without its children. However, this does not preserve event listeners and breaks any other references to the node.

The SQL Server Management Studio has implicit commit turned on, so all statements that are executed are implicitly commited.

This might be a scary thing if you come from an Oracle background where the default is to not have commands commited automatically, but it's not that much of a problem.

If you still want to use ad-hoc transactions, you can always execute

BEGIN TRANSACTION

within SSMS, and than the system waits for you to commit the data.

If you want to replicate the Oracle behaviour, and start an implicit transaction, whenever some DML/DDL is issued, you can set the SET IMPLICIT_TRANSACTIONS checkbox in

Tools -> Options -> Query Execution -> SQL Server -> ANSI

I guess your app crashes because of NullPointerException.

Change this

ListView lv = (ListView)getActivity().findViewById(R.id.lv_contact);

to

ListView lv = (ListView)rootView.findViewById(R.id.lv_contact);

assuming listview belongs to the fragment layout.

The rest of the code looks alright

Edit:

Well since you said it is not working i tried it myself

For me cache invalidation and restart didn't work. I removed the .idea and .gradle folders. If you do that, don't forget that things like build logs or something might go away though.

in other way, you can do it with javascript , in Jquery you can use something like:

$('div:visible').last()

*reedited

In your last example:

var latestCust = db.Customers
.OrderByDescending(x=> x.CreatedOn)
.FirstOrDefault();//Single or First, or doesn't matter?

Yes it does. If you try to use SingleOrDefault() and the query results in more than record you would get and exception. The only time you can safely use SingleOrDefault() is when you are expecting only 1 and only 1 result...

I think this will helpful to you...

DECLARE @ConstraintName nvarchar(200)
SELECT 
    @ConstraintName = KCU.CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS AS RC 
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS KCU
    ON KCU.CONSTRAINT_CATALOG = RC.CONSTRAINT_CATALOG  
    AND KCU.CONSTRAINT_SCHEMA = RC.CONSTRAINT_SCHEMA 
    AND KCU.CONSTRAINT_NAME = RC.CONSTRAINT_NAME
WHERE
    KCU.TABLE_NAME = 'TABLE_NAME' AND
    KCU.COLUMN_NAME = 'TABLE_COLUMN_NAME'
IF @ConstraintName IS NOT NULL EXEC('alter table TABLE_NAME drop  CONSTRAINT ' + @ConstraintName)

It will delete foreign Key Constraint based on specific table and column.

If you don't want to use the KnockoutValidation library you can write your own. Here's an example for a Mandatory field.

Add a javascript class with all you KO extensions or extenders, and add the following:

ko.extenders.required = function (target, overrideMessage) {
    //add some sub-observables to our observable
    target.hasError = ko.observable();
    target.validationMessage = ko.observable();

    //define a function to do validation
    function validate(newValue) {
    target.hasError(newValue ? false : true);
    target.validationMessage(newValue ? "" : overrideMessage || "This field is required");
    }

    //initial validation
    validate(target());

    //validate whenever the value changes
    target.subscribe(validate);

    //return the original observable
    return target;
};

Then in your viewModel extend you observable by:

self.dateOfPayment: ko.observable().extend({ required: "" }),

There are a number of examples online for this style of validation.

function rollDice(){
   return (Math.floor(Math.random()*6)+1);
}

The object, method, and property names in the .NET language bindings do not exactly correspond to those in the Java bindings. One of the principles of the project is that each language binding should "feel natural" to those comfortable coding in that language. In C#, the code you'd want for executing JavaScript is as follows

IWebDriver driver; // assume assigned elsewhere
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
string title = (string)js.ExecuteScript("return document.title");

Note that the complete documentation of the WebDriver API for .NET can be found at this link.

This adds "getWeek" method to Date.prototype which returns number of week from the beginning of the year. The argument defines which day of the week to consider the first. If no argument passed, first day is assumed Sunday.

/**
 * Get week number in the year.
 * @param  {Integer} [weekStart=0]  First day of the week. 0-based. 0 for Sunday, 6 for Saturday.
 * @return {Integer}                0-based number of week.
 */
Date.prototype.getWeek = function(weekStart) {
    var januaryFirst = new Date(this.getFullYear(), 0, 1);
    if(weekStart !== undefined && (typeof weekStart !== 'number' || weekStart % 1 !== 0 || weekStart < 0 || weekStart > 6)) {
      throw new Error('Wrong argument. Must be an integer between 0 and 6.');
    }
    weekStart = weekStart || 0;
    return Math.floor((((this - januaryFirst) / 86400000) + januaryFirst.getDay() - weekStart) / 7);
};

Found it! I forgot to hash the password when I changed it. I used this query to solve my problem:

update user set password=PASSWORD('NEW PASSWORD') where user='root';

I forgot the PASSWORD('NEW PASSWORD') and just put in the new password in plain text

The accepted answer is correct with removing URL by NSFileManager is correct, but as stated in iOS 5+ edit, the persistent store is not represented only by one file. For SQLite store it's *.sqlite, *.sqlite-shm and *.sqlite-wal ... fortunately since iOS 7+ we can use method

[NSPersistentStoreCoordinator +removeUbiquitousContentAndPersistentStoreAtURL:options:error:]

to take care of removal, so the code should be something like this:

NSPersistentStore *store = ...;
NSError *error;
NSURL *storeURL = store.URL;
NSString *storeName = ...;
NSPersistentStoreCoordinator *storeCoordinator = ...;
[storeCoordinator removePersistentStore:store error:&error];
[NSPersistentStoreCoordinator removeUbiquitousContentAndPersistentStoreAtURL:storeURL.path options:@{NSPersistentStoreUbiquitousContentNameKey: storeName} error:&error];

The answers above are incorrect, they will all run weather or not the submission is successful... You need to write an error component that will receive any errors then check if there are errors in state, if there are not then clear the form....

use .then()

example:

 const onSubmit =  e => {
e.preventDefault();
const fd = new FormData();
fd.append("ticketType", ticketType);
fd.append("ticketSubject", ticketSubject);
fd.append("ticketDescription", ticketDescription);
fd.append("itHelpType", itHelpType);
fd.append("ticketPriority", ticketPriority);
fd.append("ticketAttachments", ticketAttachments);
newTicketITTicket(fd).then(()=>{
  setTicketData({
    ticketType: "IT",
    ticketSubject: "",
    ticketDescription: "",
    itHelpType: "",
    ticketPriority: ""
  })
})  

};

I know nothing about the Android SQLite API, but if you're able to talk to it in SQL directly, you can do this:

create table if not exists mytable (col1 type, col2 type);

Which will ensure that the table is always created and not throw any errors if it already existed.

This can be solved with the mentioned depends_on directive since it's implemented now (2016):

I faced a similar problem, trying to test if jQuery is already present on a page, and if not force it's load, and then execute a function. I tried with @David Hellsing workaround, but with no chance for my needs. In fact, the onload instruction was immediately evaluated, and then the $ usage inside this function was not yet possible (yes, the huggly "$ is not a function." ^^).

So, I referred to this article : https://developer.mozilla.org/fr/docs/Web/Events/load and attached a event listener to my script object.

var script = document.createElement('script');
script.type = "text/javascript";
script.addEventListener("load", function(event) {
    console.log("script loaded :)");
    onjqloaded();
});
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(script);

For my needs, it works fine now. Hope this can help others :)

For those running pre-java7, named groups are supported by joni (Java port of the Oniguruma regexp library). Documentation is sparse, but it has worked well for us.
Binaries are available via Maven (http://repository.codehaus.org/org/jruby/joni/joni/).

As for 2018 there is still not a simple answer to the question of how to convert a PDF document to an image in C#; many libraries use Ghostscript licensed under AGPL and in most cases an expensive commercial license is required for production use.

A good alternative might be using the popular 'pdftoppm' utility which has a GPL license; it can be used from C# as command line tool executed with System.Diagnostics.Process. Popular tools are well known in the Linux world, but a windows build is also available.

If you don't want to integrate pdftoppm by yourself, you can use my PdfRenderer popular wrapper (supports both classic .NET Framework and .NET Core) - it is not free, but pricing is very affordable.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

Write the root logger as below for logging on both console and FILE

log4j.rootLogger=ERROR,console,FILE

And write the respective definitions like Target, Layout, and ConversionPattern (MaxFileSize for file etc).

I recommend for you to use Jquery plugin selectBoxIt selectBoxIt

It is nice and simple, and you can change the arrow of drop down menu.

As of Pandas 0.24.0, we can now use DataFrame.droplevel():

cols = pd.MultiIndex.from_tuples([("a", "b"), ("a", "c")])
df = pd.DataFrame([[1,2], [3,4]], columns=cols)

df.droplevel(0, axis=1) 

#   b  c
#0  1  2
#1  3  4

This is very useful if you want to keep your DataFrame method-chain rolling.

In Linux/Mac, this much practical option should also work

git commit -am "IssueNumberIAmWorkingOn --hit Enter key
> A detail here --Enter
> Another detail here --Enter
> Third line here" && git push --last Enter and it will be there

If you are working on a new branch created locally, change the git push piece with git push -u origin branch_name

If you want to edit your commit message in system editor then

git commit -a && git push 

will open the editor and once you save the message it will also push it.

Header files can contain any valid C code, since they are injected into the compilation unit by the pre-processor prior to compilation.

If a header file contains a function, and is included by multiple .c files, each .c file will get a copy of that function and create a symbol for it. The linker will complain about the duplicate symbols.

It is technically possible to create static functions in a header file for inclusion in multiple .c files. Though this is generally not done because it breaks from the convention that code is found in .c files and declarations are found in .h files.

See the discussions in C/C++: Static function in header file, what does it mean? for more explanation.

My solutions in one of my own sites, with a table:

<table id="table_numbers">
 <tr>
  <th>[...]</th>
  <th>[...]</th>
  <th>[...]</th>
  <th>Last Call</th>
  <th>Status</th>
  <th>Duration</th>
  <th>Human?</th>
  <th>[...]</th>
 </tr>
 <tr id="tr_123456">
  [...]
 </tr>
</table>

This essentially gives every row a unique id preceding with 'tr_' to allow for other numbered element ids, at server script time. The jQuery script then just gets this TR_[id] element, and fills the correct indexed cell with the json return.

The advantage is you could get the complete array from the DB, and either foreach($array as $record) to create the table html, OR (if there is an update request) you can die(json_encode($array)) before displaying the table, all in the same page, but same display code.

You can't read the transaction log file easily because that's not properly documented. There are basically two ways to do this. Using undocumented or semi-documented database functions or using third-party tools.

Note: This only makes sense if your database is in full recovery mode.

SQL Functions:

DBCC LOG and fn_dblog - more details here and here.

Third-party tools:

Toad for SQL Server and ApexSQL Log.

You can also check out several other topics where this was discussed:

• Rollback transaction using transaction log

• SQL Server Transaction Log Explorer/Analyzer

• Read the log file (*.LDF) in SQL Server 2008

One-line solution:

df.join(
    df.groupby('state').agg(state_total=('sales', 'sum')),
    on='state'
).eval('sales / state_total')

This returns a Series of per-office ratios -- can be used on it's own or assigned to the original Dataframe.

In my case I was using a gradle project with subprojects. The reason IntelliJ couldn't find declarations was that the subprojects were not built.

After investigating why subprojects were not built, I found out that using "auto-import" was breaking the subprojects.

After importing the project from build.gradle without auto-import, it worked for me.

I was getting a similar problem with SBT and slf4j. Nothing had changed, but on one machine it suddenly wouldn't build.

I tried:

• sbt clean
• deleting target/
• deleting project working directory and doing a fresh checkout/build
• deleting the ~/.sbt/<scala-version>/ folder
• deleting the offending slf4j folder from the ~/.ivy2 cache
• placing the missing slf4j jars in the expected ivy2 folder

None of the above worked.

So, I had to bite the bullet and delete my entire ~/.ivy2/ cache folder and wait for 2GB of dependencies to be downloaded again. I'm not familiar with what sort of cache manifests get written in there, but this must have been a corruption of one of them.

(using SBT 2.10.4 for Spark builds)

You actually do not want to get the path to your main class. According to your example you want to get the current working directory, i.e. directory where your program started. In this case you can just say new File(".").getAbsolutePath()

Use slidedown():

$("test").slideDown("slow");

Be very careful: NULL is a macro used mainly for pointers. The standard way of terminating a string is:

char *buffer;
...
buffer[end_position] = '\0';

This (below) works also but it is not a big difference between assigning an integer value to a int/short/long array and assigning a character value. This is why the first version is preferred and personally I like it better.

buffer[end_position] = 0; 

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

Slightly different version I wrote that keeps track of the keys along the way to get there

def print_dict(v, prefix=''):
    if isinstance(v, dict):
        for k, v2 in v.items():
            p2 = "{}['{}']".format(prefix, k)
            print_dict(v2, p2)
    elif isinstance(v, list):
        for i, v2 in enumerate(v):
            p2 = "{}[{}]".format(prefix, i)
            print_dict(v2, p2)
    else:
        print('{} = {}'.format(prefix, repr(v)))

On your data, it'll print

data['xml']['config']['portstatus']['status'] = u'good'
data['xml']['config']['target'] = u'1'
data['xml']['port'] = u'11'

It's also easy to modify it to track the prefix as a tuple of keys rather than a string if you need it that way.

I come across this problem when I tried to convert to Australian date format in excel. I split the cell with delimiter and used the following code from split cells then altered the issue areas.

=date(dd,mm,yy)

You can have any length, but of course, there can be a memory issue on the computer if the String input is too long. The output is always 32 characters.

I think this is the most elegant, as it also does not try to move ..:

mv /source/path/{.[!.],}* /destination/path

Best Regards,

JavaScript has a RegExp object which does what you want. The String object has a match() function that will help you out.

var matches = text.match(/price\[(\d+)\]\[(\d+)\]/);
var productId = matches[1];
var shopId    = matches[2];

Try

import os

os.environ['PATH']=os.environ['PATH']+';'+os.environ['CONDA_PREFIX']+r"\Library\bin\graphviz"

Modern Async Answer

The accepted answer is just plain wrong, it might work for some people because the time taken to get files from disk frees up whatever was locking the files. The fact is, this happens because files get locked by some other process/stream/action. The other answers use Thread.Sleep (Yuck) to retry deleting the directory after some time. This question needs revisiting with a more modern answer.

public static async Task<bool> TryDeleteDirectory(
   string directoryPath,
   int maxRetries = 10,
   int millisecondsDelay = 30)
{
    if (directoryPath == null)
        throw new ArgumentNullException(directoryPath);
    if (maxRetries < 1)
        throw new ArgumentOutOfRangeException(nameof(maxRetries));
    if (millisecondsDelay < 1)
        throw new ArgumentOutOfRangeException(nameof(millisecondsDelay));

    for (int i = 0; i < maxRetries; ++i)
    {
        try
        {
            if (Directory.Exists(directoryPath))
            {
                Directory.Delete(directoryPath, true);
            }

            return true;
        }
        catch (IOException)
        {
            await Task.Delay(millisecondsDelay);
        }
        catch (UnauthorizedAccessException)
        {
            await Task.Delay(millisecondsDelay);
        }
    }

    return false;
}

Unit Tests

These tests show an example of how a locked file can cause the Directory.Delete to fail and how the TryDeleteDirectory method above fixes the problem.

[Fact]
public async Task TryDeleteDirectory_FileLocked_DirectoryNotDeletedReturnsFalse()
{
    var directoryPath = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString());
    var subDirectoryPath = Path.Combine(Path.GetTempPath(), "SubDirectory");
    var filePath = Path.Combine(directoryPath, "File.txt");

    try
    {
        Directory.CreateDirectory(directoryPath);
        Directory.CreateDirectory(subDirectoryPath);

        using (var fileStream = new FileStream(filePath, FileMode.Create, FileAccess.Write, FileShare.Write))
        {
            var result = await TryDeleteDirectory(directoryPath, 3, 30);
            Assert.False(result);
            Assert.True(Directory.Exists(directoryPath));
        }
    }
    finally
    {
        if (Directory.Exists(directoryPath))
        {
            Directory.Delete(directoryPath, true);
        }
    }
}

[Fact]
public async Task TryDeleteDirectory_FileLockedThenReleased_DirectoryDeletedReturnsTrue()
{
    var directoryPath = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString());
    var subDirectoryPath = Path.Combine(Path.GetTempPath(), "SubDirectory");
    var filePath = Path.Combine(directoryPath, "File.txt");

    try
    {
        Directory.CreateDirectory(directoryPath);
        Directory.CreateDirectory(subDirectoryPath);

        Task<bool> task;
        using (var fileStream = new FileStream(filePath, FileMode.Create, FileAccess.Write, FileShare.Write))
        {
            task = TryDeleteDirectory(directoryPath, 3, 30);
            await Task.Delay(30);
            Assert.True(Directory.Exists(directoryPath));
        }

        var result = await task;
        Assert.True(result);
        Assert.False(Directory.Exists(directoryPath));
    }
    finally
    {
        if (Directory.Exists(directoryPath))
        {
            Directory.Delete(directoryPath, true);
        }
    }
}

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

Here is an extension of @Trasp's answer that has additional logic for handling the corner case of a file that has only one line. It may be useful to handle this case if you repeatedly want to read the last line of a file that is continuously being updated. Without this, if you try to grab the last line of a file that has just been created and has only one line, IOError: [Errno 22] Invalid argument will be raised.

def tail(filepath):
    with open(filepath, "rb") as f:
        first = f.readline()      # Read the first line.
        f.seek(-2, 2)             # Jump to the second last byte.
        while f.read(1) != b"\n": # Until EOL is found...
            try:
                f.seek(-2, 1)     # ...jump back the read byte plus one more.
            except IOError:
                f.seek(-1, 1)
                if f.tell() == 0:
                    break
        last = f.readline()       # Read last line.
    return last

Converting the output is too late; the calculation has already taken place in integer arithmetic. You need to convert the inputs to double:

System.out.println((double)completed/(double)total);

Note that you don't actually need to convert both of the inputs. So long as one of them is double, the other will be implicitly converted. But I prefer to do both, for symmetry.

the answers here are correct and i liked @Jyo the Whiff idea of a show and hide fragment implementation except the way he has it currently would hide the fragment on the first run so i added a slight change in that i added the isAdded check and show the fragment if its not already

public void showHideCardPreview(int id) {
    FragmentManager fm = getSupportFragmentManager();
    Bundle b = new Bundle();
    b.putInt(Constants.CARD, id);
    cardPreviewFragment.setArguments(b);
    FragmentTransaction ft = fm.beginTransaction()
        .setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out);
    if (!cardPreviewFragment.isAdded()){
        ft.add(R.id.full_screen_container, cardPreviewFragment);
        ft.show(cardPreviewFragment);
    } else {
        if (cardPreviewFragment.isHidden()) {
            Log.d(TAG,"++++++++++++++++++++ show");
            ft.show(cardPreviewFragment);
        } else {
            Log.d(TAG,"++++++++++++++++++++ hide");
            ft.hide(cardPreviewFragment);
        }
    }

    ft.commit();
} 

Though you may prefer the pure Python solution provided by the python-daemon module, there is a daemon(3) function in libc -- at least, on BSD and Linux -- which will do the right thing.

Calling it from python is easy:

import ctypes

ctypes.CDLL(None).daemon(0, 0) # Read the man-page for the arguments' meanings

The only remaining thing to do is creation (and locking) of the PID-file. But that you can handle yourself...

i wrote a very(!) little helper method around the adobereader to bulk-print pdf from c#...:

  public static bool Print(string file, string printer) {
     try {
        Process.Start(
           Registry.LocalMachine.OpenSubKey(
                @"SOFTWARE\Microsoft\Windows\CurrentVersion" +
                @"\App Paths\AcroRd32.exe").GetValue("").ToString(),
           string.Format("/h /t \"{0}\" \"{1}\"", file, printer));
        return true;
     } catch { }
     return false;
  }

one cannot rely on the return-value of the method btw...

If you are storing keys/values as strings, then this will work:

HashMap<String, String> newMap = new HashMap<String, String>();
newMap.put("my_code", "shhh_secret");
String value = newMap.get("my_code");

The question is what gets populated in the HashMap (key & value)

If you forward-declare Flight and Landing in Event.h, then you should be fixed.

Remember to #include "Flight.h" and #include "Landing.h" in your implementation file for Event.

The general rule of thumb is: if you derive from it, or compose from it, or use it by value, the compiler must know its full definition at the time of declaration. If you compose from a pointer-to-it, the compiler will know how big a pointer is. Similarly, if you pass a reference to it, the compiler will know how big the reference is, too.

this method worked for me
First, put the line below at the beginning of your controller:

use File;

below namespace in your php file Second:

 $destinationPath = 'your_path';
 File::delete($destinationPath.'/your_file');

$destinationPath --> the folder inside folder public.

You can use the Django-Truncate library to delete all data of a table without destroying the table structure.

Example:

1. First, install django-turncate using your terminal/command line:

pip install django-truncate

2. Add "django_truncate" to your INSTALLED_APPS in the settings.py file:

INSTALLED_APPS = [
    ...
    'django_truncate',
]

3. Use this command in your terminal to delete all data of the table from the app.

python manage.py truncate --apps app_name --models table_name

Just collapse the table borders and remove the borders from table cells (td elements).

table {
    border: 1px solid #CCC;
    border-collapse: collapse;
}

td {
    border: none;
}

Without explicitly setting border-collapse cross-browser removal of table cell borders is not guaranteed.

Instead of using RequestContextHolder directly, you can also use ServletUriComponentsBuilder and its static methods:

• ServletUriComponentsBuilder.fromCurrentContextPath()
• ServletUriComponentsBuilder.fromCurrentServletMapping()
• ServletUriComponentsBuilder.fromCurrentRequestUri()
• ServletUriComponentsBuilder.fromCurrentRequest()

They use RequestContextHolder under the hood, but provide additional flexibility to build new URLs using the capabilities of UriComponentsBuilder.

Example:

ServletUriComponentsBuilder builder = ServletUriComponentsBuilder.fromCurrentRequestUri();
builder.scheme("https");
builder.replaceQueryParam("someBoolean", false);
URI newUri = builder.build().toUri();

If we don’t use ES2015 and don’t have fill(), just use .apply()

See https://stackoverflow.com/a/47041157/1851492

let Array2D = (r, c, fill) => Array.apply(null, new Array(r)).map(function() {return Array.apply(null, new Array(c)).map(function() {return fill})})_x000D_
_x000D_
console.log(JSON.stringify(Array2D(3,4,0)));_x000D_
console.log(JSON.stringify(Array2D(4,5,1)));

Python functions always return a unique value. The comma operator is the constructor of tuples so self.first_name, self.last_name evaluates to a tuple and that tuple is the actual value the function is returning.

the code behind for the window:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModelBase();
    }
}

The ViewModel:

public class ViewModelBase
{
    private ICommand _clickCommand;
    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
        }
    }
     public bool CanExecute
     {
        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

Command Handler:

 public class CommandHandler : ICommand
{
    private Action _action;
    private Func<bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler
    /// </summary>
    /// <param name="action">Action to be executed by the command</param>
    /// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
    public CommandHandler(Action action, Func<bool> canExecute)
    {
        _action = action;
        _canExecute = canExecute;
    }

    /// <summary>
    /// Wires CanExecuteChanged event 
    /// </summary>
    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    /// <summary>
    /// Forcess checking if execute is allowed
    /// </summary>
    /// <param name="parameter"></param>
    /// <returns></returns>
    public bool CanExecute(object parameter)
    {
        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

These functions work well

In Java

private void setActionbarTextColor(ActionBar actBar, int color) {

    String title = actBar.getTitle().toString();
    Spannable spannablerTitle = new SpannableString(title);
    spannablerTitle.setSpan(new ForegroundColorSpan(color), 0, spannablerTitle.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    actBar.setTitle(spannablerTitle);

}

then to use it just feed it your action bar and the new color i.e.

ActionBar actionBar = getActionBar();    // Or getSupportActionBar() if using appCompat
int red = Color.RED
setActionbarTextColor(actionBar, red);

In Kotlin

You can use an extension function like this:

private fun ActionBar.setTitleColor(color: Int) {
    val text = SpannableString(title ?: "")
    text.setSpan(ForegroundColorSpan(color),0,text.length, Spannable.SPAN_INCLUSIVE_INCLUSIVE)
    title = text
}

And then apply to your ActionBar with

actionBar?.setTitleColor(Color.RED)

It require to include Content-Type:application/json in web api request header section when not mention any content then by default it is Content-Type:text/plain passes to request.

Best way to test api on postman tool.

For batch processing with files in folder aiming for 190 VBR and file extension = .mp3 instead of .ac3.mp3 you can use the following code

Change .ac3 to whatever the source audio format is.

ffmpeg mp3 settings

for f in *.ac3 ; do ffmpeg -i "$f" -acodec libmp3lame -q:a 2 "${f%.*}.mp3"; done

echo $? - Gives the EXIT STATUS of the most recently executed command . This EXIT STATUS would most probably be a number with ZERO implying Success and any NON-ZERO value indicating Failure

? - This is one special parameter/variable in bash.

$? - It gives the value stored in the variable "?".

Some similar special parameters in BASH are 1,2,*,# ( Normally seen in echo command as $1 ,$2 , $* , $# , etc., ) .

@property (strong) NSNumberFormatter *numberFormatter;
@property (strong) NSString *oldStringValue;

- (void)awakeFromNib 
{
  [super awakeFromNib];
  self.numberFormatter = [[NSNumberFormatter alloc] init];
  self.oldStringValue = self.stringValue;
  [self setDelegate:self];
}

- (void)controlTextDidChange:(NSNotification *)obj
{
  NSNumber *number = [self.numberFormatter numberFromString:self.stringValue];
  if (number) {
    self.oldStringValue = self.stringValue;
  } else {
    self.stringValue = self.oldStringValue;
  }
}

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

Probably won't help but you could try creating a CSV table with that content:

DROP TABLE IF EXISTS foo_export;
CREATE TABLE foo_export LIKE foo;
ALTER TABLE foo_export ENGINE=CSV;
INSERT INTO foo_export SELECT id, 
   client,
   project,
   task,
   REPLACE(REPLACE(ifnull(ts.description,''),'\n',' '),'\r',' ') AS description, 
   time,
   date
  FROM ....

On Windows: if you had to mount two directories E:\data\dev & E:\data\dev2

Use:

docker run -v E:\data\dev:c:/downloads -v E:\data\dev2 c:/downloads2 -i --publish 1111:80 -P SomeBuiltContainerName:SomeLabel

They key is the backslash escape character will not work with the right square bracket inside of the character class square brackets (it is interpreted as a literal backslash inside the character class square brackets). Add the right square bracket with an OR at the end like this:

select EmpNo, SampleText
from test 
where NOT regexp_like(SampleText, '[ A-Za-z0-9.{}[]|]');

If you don't want to mess with ready libraries you can just make a class like this.

public class JsonConverter {

//Your class here, or you can define it in the constructor
Class requestclass = PositionKeeperRequestTest.class;

//Filename
String jsonFileName;

//constructor
public myJson(String jsonFileName){
    this.jsonFileName = jsonFileName;
}


//Returns a json object from an input stream
private JSONObject getJsonObject(){

    //Create input stream
    InputStream inputStreamObject = getRequestclass().getResourceAsStream(jsonFileName);

   try {
       BufferedReader streamReader = new BufferedReader(new InputStreamReader(inputStreamObject, "UTF-8"));
       StringBuilder responseStrBuilder = new StringBuilder();

       String inputStr;
       while ((inputStr = streamReader.readLine()) != null)
           responseStrBuilder.append(inputStr);

       JSONObject jsonObject = new JSONObject(responseStrBuilder.toString());

       //returns the json object
       return jsonObject;

   } catch (IOException e) {
       e.printStackTrace();
   } catch (JSONException e) {
       e.printStackTrace();
   }

    //if something went wrong, return null
    return null;
}

private Class getRequestclass(){
    return requestclass;
}
}

Then, you can use it like this:

JSONObject jObject = new JsonConverter(FILE_NAME).getJsonObject();

To incorporate third-party DLLs into my VS 2008 C++ project I did the following (you should be able to translate into 2010, 2012 etc.)...

I put the header files in my solution with my other header files, made changes to my code to call the DLLs' functions (otherwise why would we do all this?). :^) Then I changed the build to link the LIB code into my EXE, to copy the DLLs into place, and to clean them up when I did a 'clean' - I explain these changes below.

Suppose you have 2 third-party DLLs, A.DLL and B.DLL, and you have a stub LIB file for each (A.LIB and B.LIB) and header files (A.H and B.H).

• Create a "lib" directory under your solution directory, e.g. using Windows Explorer.
• Copy your third-party .LIB and .DLL files into this directory

(You'll have to make the next set of changes once for each source build target that you use (Debug, Release).)

1. Make your EXE dependent on the LIB files

   • Go to Configuration Properties -> Linker -> Input -> Additional Dependencies, and list your .LIB files there one at a time, separated by spaces: A.LIB B.LIB
   • Go to Configuration Properties -> General -> Additional Library Directories, and add your "lib" directory to any you have there already. Entries are separated by semicolons. For example, if you already had $(SolutionDir)fodder there, you change it to $(SolutionDir)fodder;$(SolutionDir)lib to add "lib".

2. Force the DLLs to get copied to the output directory

   • Go to Configuration Properties -> Build Events -> Post-Build Event
   • Put the following in for Command Line (for the switch meanings, see "XCOPY /?" in a DOS window):

   XCOPY "$(SolutionDir)"\lib\*.DLL "$(TargetDir)" /D /K /Y

   • You can put something like this for Description:

   Copy DLLs to Target Directory

   • Excluded From Build should be No. Click OK.

3. Tell VS to clean up the DLLs when it cleans up an output folder:

   • Go to Configuration Properties -> General -> Extensions to Delete on Clean, and click on "..."; add *.dll to the end of the list and click OK.

Oh my. This is actually so simple!

Follow up edit 2013-10-29 In the case where I have a fairly complex MultiIndex, I think I prefer the groupby approach. Here's simple example for posterity:

import numpy as np
import pandas

# fake index
idx = pandas.MultiIndex.from_tuples([('a', letter) for letter in list('abcde')])

# random data + naming the index levels
df1 = pandas.DataFrame(np.random.normal(size=(5,2)), index=idx, columns=['colA', 'colB'])
df1.index.names = ['iA', 'iB']

# artificially append some duplicate data
df1 = df1.append(df1.select(lambda idx: idx[1] in ['c', 'e']))
df1
#           colA      colB
#iA iB                    
#a  a  -1.297535  0.691787
#   b  -1.688411  0.404430
#   c   0.275806 -0.078871
#   d  -0.509815 -0.220326
#   e  -0.066680  0.607233
#   c   0.275806 -0.078871  # <--- dup 1
#   e  -0.066680  0.607233  # <--- dup 2

and here's the important part

# group the data, using df1.index.names tells pandas to look at the entire index
groups = df1.groupby(level=df1.index.names)  
groups.last() # or .first()
#           colA      colB
#iA iB                    
#a  a  -1.297535  0.691787
#   b  -1.688411  0.404430
#   c   0.275806 -0.078871
#   d  -0.509815 -0.220326
#   e  -0.066680  0.607233

You mean like:

String names[] = {"Ankit","Bohra","Xyz"};

But you can only do this in the same statement when you declare it

My solution was to modify the java.security file:

\SoapUI-5.3.0\jre\lib\security\java.security

Comment code syntax:

#jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024

I made a calendar using:

http://social.technet.microsoft.com/wiki/contents/articles/22776.t-sql-calendar-table.aspx

then a Store procedure passing two dates and thats all:

USE DB_NAME;

CREATE PROCEDURE [dbo].[USP_LISTAR_RANGO_FECHAS]
@FEC_INICIO date,
@FEC_FIN date
AS
Select Date from CALENDARIO where Date BETWEEN @FEC_INICIO AND @FEC_FIN;

Use this simple javascript code to redirect page to another page using specific interval of time...

Please add this code into your web site page, which is you want to redirect :

<script type="text/javascript">

   },3000); /* 1000 = 1 second*/
})();
</script>

If you keep the algorithm meaningful in any way, O(n!) is the worst upper bound you can achieve.

Since checking each possibility for a permutations of a set to be sorted will take n! steps, you can't get any worse than that.

If you're doing more steps than that then the algorithm has no real useful purpose. Not to mention the following simple sorting algorithm with O(infinity):

list = someList
while (list not sorted):
    doNothing

Following link might help you. Here's code from the following link.

        RemoteEndpointMessageProperty remoteProperty = property as RemoteEndpointMessageProperty;

Use list comprehensions when the result needs to be iterated over multiple times, or where speed is paramount. Use generator expressions where the range is large or infinite.

See Generator expressions and list comprehensions for more info.

To use BeginForm, here's the way to use it:

 using(Html.BeginForm("uploadfiles", 
"home", FormMethod.POST, new Dictionary<string, object>(){{"type", "file"}})

A very elegant way is to use ng-controller to run a single controller outside of the ng-view:

<div class="collapse navbar-collapse" ng-controller="HeaderController">
    <ul class="nav navbar-nav">
        <li ng-class="{ active: isActive('/')}"><a href="/">Home</a></li>
        <li ng-class="{ active: isActive('/dogs')}"><a href="/dogs">Dogs</a></li>
        <li ng-class="{ active: isActive('/cats')}"><a href="/cats">Cats</a></li>
    </ul>
</div>
<div ng-view></div>

and include in controllers.js:

function HeaderController($scope, $location) 
{ 
    $scope.isActive = function (viewLocation) { 
        return viewLocation === $location.path();
    };
}

i think token must include all the needed information encoded inside it, which makes authentication by validating the token and decoding the info https://www.oauth.com/oauth2-servers/access-tokens/self-encoded-access-tokens/

To have access to stuff provided by math module, like pi. You need to import the module first:

import math
print (math.pi)

This's Because!

1. The timeout function callbacks are all running well after the completion of the loop. In fact, as timers go, even if it was setTimeout(.., 0) on each iteration, all those function callbacks would still run strictly after the completion of the loop, that's why 3 was reflected!
2. all two of those functions, though they are defined separately in each loop iteration, are closed over the same shared global scope, which has, in fact, only one i in it.

the Solution's declaring a single scope for each iteration by using a self-function executed(anonymous one or better IIFE) and having a copy of i in it, like this:

for (var i = 1; i <= 2; i++) {

     (function(){

         var j = i;
         setTimeout(function() { console.log(j) }, 100);

     })();

}

the cleaner one would be

for (var i = 1; i <= 2; i++) {

     (function(i){ 

         setTimeout(function() { console.log(i) }, 100);

     })(i);

}

The use of an IIFE(self-executed function) inside each iteration created a new scope for each iteration, which gave our timeout function callbacks the opportunity to close over a new scope for each iteration, one which had a variable with the right per-iteration value in it for us to access.

the absolutely minimal (and correct, unlike many of the answers above) version is:

function Monkey(param){
  this.someProperty = param;
}
Monkey.prototype = Object.create(Monster.prototype);
Monkey.prototype.eatBanana = function(banana){ banana.eat() }

That's all. You can read here the longer explanation

@Amirali

console.log(document.getElementById("SAVE_FOOTER"));
document.getElementById("SAVE_FOOTER").attribute("onclick","console.log('c')");

throws:

Uncaught TypeError: document.getElementById(...).attribute is not a function

Note that SimpleDateFormat format pattern Z is for RFC 822 time zone and pattern X is for ISO 8601 (this standard supports single letter time zone names like Z for Zulu).

So new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX") produces a format that can parse both "2013-03-11T01:38:18.309Z" and "2013-03-11T01:38:18.309+0000" and will give you the same result.

Unfortunately, as far as I can tell, you can't get this format to generate the Z for Zulu version, which is annoying.

I actually have more trouble on the JavaScript side to deal with both formats.

There are several ways to do it. The subplots method creates the figure along with the subplots that are then stored in the ax array. For example:

import matplotlib.pyplot as plt

x = range(10)
y = range(10)

fig, ax = plt.subplots(nrows=2, ncols=2)

for row in ax:
    for col in row:
        col.plot(x, y)

plt.show()

However, something like this will also work, it's not so "clean" though since you are creating a figure with subplots and then add on top of them:

fig = plt.figure()

plt.subplot(2, 2, 1)
plt.plot(x, y)

plt.subplot(2, 2, 2)
plt.plot(x, y)

plt.subplot(2, 2, 3)
plt.plot(x, y)

plt.subplot(2, 2, 4)
plt.plot(x, y)

plt.show()

I followed Alohci's recommendation of looping in reverse because it's a live nodeList. Here's what I did for those who are curious...

  var activeObjects = documents.getElementsByClassName('active'); // a live nodeList

  //Use a reverse-loop because the array is an active NodeList
  while(activeObjects.length > 0) {
    var lastElem = activePaths[activePaths.length-1]; //select the last element

    //Remove the 'active' class from the element.  
    //This will automatically update the nodeList's length too.
    var className = lastElem.getAttribute('class').replace('active','');
    lastElem.setAttribute('class', className);
  }

public mySentences:Array<Object> = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

Or rather,

export interface type{
    id:number;
    text:string;
}

public mySentences:type[] = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

enum Enum{ Banana, Orange, Apple } ;
static const char * EnumStrings[] = { "bananas & monkeys", "Round and orange", "APPLE" };

const char * getTextForEnum( int enumVal )
{
  return EnumStrings[enumVal];
}

Writing the actual condition can be the tricky part, so I tend to

1. Set a regular breakpoint.
2. Run the code until the breakpoint is hit for the first time.
3. Use the Immediate Window (Debug > Windows > Immediate) to test your expression.
4. Right-click the breakpoint, click Condition and paste in your expression.

Advantages of using the Immediate window:

• It has IntelliSense.
• You can be sure that the variables in the expression are in scope when the expression is evaluated.
• You can be sure your expression returns true or false.

This example breaks when the code is referring to a table with the name "Setting":

table.GetTableName().Contains("Setting")

There are two possibilities:

Every line prepended with //

ctrl + / to comment
ctrl + \ to uncomment

Note: on recent eclipse cdt, ctrl + / is used to toggle comments (and ctrl + \ has no more effect)

Complete block surrounded with block comments /*

ctrl + shift + / to comment
ctrl + shift + \ to remove

You can use the file utility to give you an indication of the type of line endings.

Unix:

$ file testfile1.txt
testfile.txt: ASCII text

"DOS":

$ file testfile2.txt
testfile2.txt: ASCII text, with CRLF line terminators

To convert from "DOS" to Unix:

$ dos2unix testfile2.txt

To convert from Unix to "DOS":

$ unix2dos testfile1.txt

Converting an already converted file has no effect so it's safe to run blindly (i.e. without testing the format first) although the usual disclaimers apply, as always.

   UPDATE tbl_ClientNotes
    SET 
      ordering=ISNULL@ordering,ordering),

      content=isnull(@content,content)

I think I remember seeing before that if you are updating to the same value SQL Server will actually recognize this and won't do an unnecessary write.

Try This

private String getFilename() {
    String filepath = Environment.getExternalStorageDirectory().getPath();
    File file = new File(filepath + "/AudioRecorder" );
    if (!file.exists()) {
        file.mkdirs();
    }
    return (file.getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp4");
}

The issue is that the Android User-Agent is a general User-Agent and there is no difference between tablet Android and mobile Android.

This is incorrect. Mobile Android has "Mobile" string in the User-Agent header. Tablet Android does not.

But it is worth mentioning that there are quite a few tablets that report "Mobile" Safari in the userAgent and the latter is not the only/solid way to differentiate between Mobile and Tablet.

It looks like you override public Map<String, String> getHeaders(), defined in Request, to return your desired HTTP headers.

MimeTypeMap.getSingleton().getExtensionFromMimeType(file.getName());

Probably, this is the easiest solution.

https://developer.android.com/reference/android/webkit/MimeTypeMap

https://developer.android.com/reference/java/net/URLConnection.html#guessContentTypeFromName(java.lang.String)

private void openFile(File file) {

    Uri uri = Uri.fromFile(file);

    Intent intent = new Intent(Intent.ACTION_VIEW);

    intent.setDataAndType(uri, MimeTypeMap.getSingleton().getExtensionFromMimeType(file.getName()));


    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(Intent.createChooser(intent, "Open " + file.getName() + " with ..."));
}

The other answers are better from a conceptual point of view. However, you can just left-pad the numbers with the appropriate number of ' ' to make them line up.

* Note: I did not at first recognize that a numbered list was being used. I thought the list was being explicitly generated.

Try looking for Windows Error Reporting events in the affected machine's Event Viewer, specifically for iexplore.exe. That might give you a pointer for what component is getting loaded in IE that is causing the crash. Even more precise would be to launch IE under a debugger (e.g. windbg), repro the crash and then get a call stack. If you have a bad 3rd party add-on, it should be towards the top of the call stack. Though you said that it "isn't really an option" it will be important for you to identify a possible incompatibility and either reach out to the add-on developer, or workaround the issue on your side.

Since using the @Value("new Long("myconfig")") with cast could throw error on startup if the config is not found or if not in the same expected number format

We used the following approach and is working as expected with fail safe check.

@Configuration()
public class MyConfiguration {

   Long DEFAULT_MAX_IDLE_TIMEOUT = 5l;

   @Value("db.timeoutInString")
   private String timeout;

   public Long getTimout() {
        final Long timoutVal = StringUtil.parseLong(timeout);
        if (null == timoutVal) {
            return DEFAULT_MAX_IDLE_TIMEOUT;
        }
        return timoutVal;
    }
}
   

Lodash unset is suitable for removing a few unwanted keys.

const myObj = {
    keyOne: "hello",
    keyTwo: "world"
}

unset(myObj, "keyTwo");

console.log(myObj); /// myObj = { keyOne: "hello" }

if params[:pid] is a string, which if it came from a form, it is, you'll probably need to use

The string will be loaded into the MemoryStream, and you can read from it. See Encoding.GetBytes(...), which has also been implemented for a few other encodings.

When your are trying to apply prod on string type of value like:

['-214' '-153' '-58' ..., '36' '191' '-37']

you will get the error.

Solution: Append only integer value like [1,2,3], and you will get your expected output.

If the value is in string format before appending then, in the array you can convert the type into int type and store it in a list.

Use DISTINCT to remove duplicate GROUPING SETS from the GROUP BY clause

In a completely silly example using GROUPING SETS() in general (or the special grouping sets ROLLUP() or CUBE() in particular), you could use DISTINCT in order to remove the duplicate values produced by the grouping sets again:

SELECT DISTINCT actors
FROM (VALUES('a'), ('a'), ('b'), ('b')) t(actors)
GROUP BY CUBE(actors, actors)

With DISTINCT:

actors
------
NULL
a
b

Without DISTINCT:

actors
------
a
b
NULL
a
b
a
b

But why, apart from making an academic point, would you do that?

Use DISTINCT to find unique aggregate function values

In a less far-fetched example, you might be interested in the DISTINCT aggregated values, such as, how many different duplicate numbers of actors are there?

SELECT DISTINCT COUNT(*)
FROM (VALUES('a'), ('a'), ('b'), ('b')) t(actors)
GROUP BY actors

Answer:

count
-----
2

Use DISTINCT to remove duplicates with more than one GROUP BY column

Another case, of course, is this one:

SELECT DISTINCT actors, COUNT(*)
FROM (VALUES('a', 1), ('a', 1), ('b', 1), ('b', 2)) t(actors, id)
GROUP BY actors, id

With DISTINCT:

actors  count
-------------
a       2
b       1

Without DISTINCT:

actors  count
-------------
a       2
b       1
b       1

For more details, I've written some blog posts, e.g. about GROUPING SETS and how they influence the GROUP BY operation, or about the logical order of SQL operations (as opposed to the lexical order of operations).

Infinity, NaN and subnormals

These are important caveats that no other answer has mentioned so far.

First read this introduction to IEEE 754 and subnormal numbers: What is a subnormal floating point number?

Then, for single precision floats (32-bit):

• IEEE 754 says that if the exponent is all ones (0xFF == 255), then it represents either NaN or Infinity.

  This is why the largest non-infinite number has exponent 0xFE == 254 and not 0xFF.

  Then with the bias, it becomes:

  254 - 127 == 127
  

• FLT_MIN is the smallest normal number. But there are smaller subnormal ones! Those take up the -127 exponent slot.

Just to add to yamen's answer, which is perfect for images but not so much for text.

If you are trying to use this to scale text, like say a Word document (which is in this case in bytes from Word Interop), you will need to make a few modifications or you will get giant bars on the side.

May not be perfect but works for me!

using (MemoryStream ms = new MemoryStream(wordBytes))
{
    float width = 3840;
    float height = 2160;
    var brush = new SolidBrush(Color.White);

    var rawImage = Image.FromStream(ms);
    float scale = Math.Min(width / rawImage.Width, height / rawImage.Height);
    var scaleWidth  = (int)(rawImage.Width  * scale);
    var scaleHeight = (int)(rawImage.Height * scale);
    var scaledBitmap = new Bitmap(scaleWidth, scaleHeight);

    Graphics graph = Graphics.FromImage(scaledBitmap);
    graph.InterpolationMode = InterpolationMode.High;
    graph.CompositingQuality = CompositingQuality.HighQuality;
    graph.SmoothingMode = SmoothingMode.AntiAlias;
    graph.FillRectangle(brush, new RectangleF(0, 0, width, height));
    graph.DrawImage(rawImage, new Rectangle(0, 0 , scaleWidth, scaleHeight));

    scaledBitmap.Save(fileName, ImageFormat.Png);
    return scaledBitmap;
}

According to the documentation.

If you are running on the TensorFlow or CNTK backends, your code will automatically run on GPU if any available GPU is detected.

You can check what all devices are used by tensorflow by -

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

Also as suggested in this answer

import tensorflow as tf
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

This will print whether your tensorflow is using a CPU or a GPU backend. If you are running this command in jupyter notebook, check out the console from where you have launched the notebook.

If you are sceptic whether you have installed the tensorflow gpu version or not. You can install the gpu version via pip.

pip install tensorflow-gpu

You can not use strtotime as your time format is not within the supported date and time formats of PHP.

Therefor, you have to create a valid date format first making use of createFromFormat function.

//creating a valid date format
$newDate = DateTime::createFromFormat('YmdHi', $longdate);

//formating the date as we want
$finalDate = $newDate->format('D'); 

public void run(final String scriptSrc) { 
        webView.post(new Runnable() {
            @Override
            public void run() { 
                webView.loadUrl("javascript:" + scriptSrc); 
            }
        }); 
    }

Sometimes you'll need to specify PATH and GEM_PATH using crontab with rvm.

Like this:

# top of crontab file
PATH=/home/user_name/.rvm/gems/ruby-2.2.0/bin:/home/user_name/.rvm/gems/ruby-2.2.0@global/bin:/home/user_name/.rvm/rubies/ruby-2.2.$
GEM_PATH=/home/user_name/.rvm/gems/ruby-2.2.0:/home/user_name/.rvm/gems/ruby-2.2.0@global

# jobs
00 00 * * * ruby path/to/your/script.rb
00 */4 * * * ruby path/to/your/script2.rb
00 8,12,22 * * * ruby path/to/your/script3.rb

sys.argv represents the command line options you execute a script with.

sys.argv[0] is the name of the script you are running. All additional options are contained in sys.argv[1:].

You are attempting to open a file that uses sys.argv[1] (the first argument) as what looks to be the directory.

Try running something like this:

python ConcatenateFiles.py /tmp

You can use this with only two parameter

function whatever($array, $val) {
    foreach ($array as $item)
        if (isset($item) && in_array($val,$item))
            return 1;
    return 0;
}

You can obfuscate it, but there's no way of protecting it completely.

example obfuscator: https://obfuscator.io

Two options:

• VLOOKUP function in its own cell: =VLOOKUP(A1, B:B, 1, 0) (in say, C1), then formula referencing C1: =IF( C1 > 10, C1 - 10, C1 )
• create a UDF:

Function MyFunc(a1, a2, a3, a4)
    Dim v as Variant
    v = Application.WorksheetFunction.VLookup(a1, a2, a3, a4)
    If v > 10 Then
        MyFunc = v - 10
    Else
        MyFunc = v
    End If
End Function

Try setting the timeout value in your web service proxy class:

WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds

How about this. using the modulo operator

if(a%b==0) 
{
    System.out.println("b is a factor of a. i.e. the result of a/b is going to be an integer");
}
else
{
    System.out.println("b is NOT a factor of a");
}

All your controls are belong to us!

Fionnuala answered this correctly but skimmers like me would find it easy to miss the point.

You don't refresh the subFORM you refresh the subform CONTROL. In fact, if you check with allforms() the subForm isn't even loaded as far as access is concerned.

On the main form look at the label the subform wizard provided or select the subform by clicking once or on the border around it and look at the "caption" in the "Other" tab in properties. That's the name you use for requerying, not the name of the form that appears in the navigation panel.

In my case I had a subform called frmInvProdSub and I tried for many hours to figure out why Access didn't think it existed. I gave up, deleted the form and re-created it. The very last step is telling it what you want to call the control so I called it frmInvProdSub and finished the wizard. Then I tried and voila, it worked!

When I looked at the form name in the navigation window I realized I'd forgotten to put "Sub" in the name! That's when it clicked. The CONTROL is called frmInvProdSub, not the form and using the control name works.

Of course if both names are identical then you didn't have this problem lol.

You’ll want to do:

I think your code is a bit too complicated and it needs more structure, because otherwise you'll be lost in all equations and operations. In the end this regression boils down to four operations:

1. Calculate the hypothesis h = X * theta
2. Calculate the loss = h - y and maybe the squared cost (loss^2)/2m
3. Calculate the gradient = X' * loss / m
4. Update the parameters theta = theta - alpha * gradient

In your case, I guess you have confused m with n. Here m denotes the number of examples in your training set, not the number of features.

Let's have a look at my variation of your code:

import numpy as np
import random

# m denotes the number of examples here, not the number of features
def gradientDescent(x, y, theta, alpha, m, numIterations):
    xTrans = x.transpose()
    for i in range(0, numIterations):
        hypothesis = np.dot(x, theta)
        loss = hypothesis - y
        # avg cost per example (the 2 in 2*m doesn't really matter here.
        # But to be consistent with the gradient, I include it)
        cost = np.sum(loss ** 2) / (2 * m)
        print("Iteration %d | Cost: %f" % (i, cost))
        # avg gradient per example
        gradient = np.dot(xTrans, loss) / m
        # update
        theta = theta - alpha * gradient
    return theta


def genData(numPoints, bias, variance):
    x = np.zeros(shape=(numPoints, 2))
    y = np.zeros(shape=numPoints)
    # basically a straight line
    for i in range(0, numPoints):
        # bias feature
        x[i][0] = 1
        x[i][1] = i
        # our target variable
        y[i] = (i + bias) + random.uniform(0, 1) * variance
    return x, y

# gen 100 points with a bias of 25 and 10 variance as a bit of noise
x, y = genData(100, 25, 10)
m, n = np.shape(x)
numIterations= 100000
alpha = 0.0005
theta = np.ones(n)
theta = gradientDescent(x, y, theta, alpha, m, numIterations)
print(theta)

At first I create a small random dataset which should look like this:

As you can see I also added the generated regression line and formula that was calculated by excel.

You need to take care about the intuition of the regression using gradient descent. As you do a complete batch pass over your data X, you need to reduce the m-losses of every example to a single weight update. In this case, this is the average of the sum over the gradients, thus the division by m.

The next thing you need to take care about is to track the convergence and adjust the learning rate. For that matter you should always track your cost every iteration, maybe even plot it.

If you run my example, the theta returned will look like this:

Iteration 99997 | Cost: 47883.706462
Iteration 99998 | Cost: 47883.706462
Iteration 99999 | Cost: 47883.706462
[ 29.25567368   1.01108458]

Which is actually quite close to the equation that was calculated by excel (y = x + 30). Note that as we passed the bias into the first column, the first theta value denotes the bias weight.

Another method (mentioned in this SO answer) will keep the history in the terminal and give you a very deep track record of the file itself:

git log --follow -p -- file

This will show the entire history of the file (including history beyond renames and with diffs for each change).

In other words, if the file named bar was once named foo, then git log -p bar (without the --follow option) will only show the file's history up to the point where it was renamed -- it won't show the file's history when it was known as foo. Using git log --follow -p bar will show the file's entire history, including any changes to the file when it was known as foo.

You can try below code. it’s very easy method for push new fragment from old fragment.

private int mContainerId;
private FragmentTransaction fragmentTransaction;
private FragmentManager fragmentManager;
private final static String TAG = "DashBoardActivity";

public void replaceFragment(Fragment fragment, String TAG) {

    try {
        fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(mContainerId, fragment, tag);
        fragmentTransaction.addToBackStack(tag);
        fragmentTransaction.commitAllowingStateLoss();

    } catch (Exception e) {
        // TODO: handle exception
    }

}

Use the first example. If the key doesn't exist it will be added.

var a = new Array();
a['name'] = 'oscar';
alert(a['name']);

Will pop up a message box containing 'oscar'.

Try:

var text = 'name = oscar'
var dict = new Array()
var keyValuePair = text.replace(/ /g,'').split('=');
dict[ keyValuePair[0] ] = keyValuePair[1];
alert( dict[keyValuePair[0]] );

The best safe way is: <%= sanitize @x %>

It will avoid XSS!

Some answers mentioned using 'splice', which did as Chance Smith said mutated the array. I would suggest you to use the Method call 'slice' (Document for 'slice' is here) which make a copy of the original array.

Here's one that works well in JavaScript. It's in a string because that's what the Dojo widget was expecting.

It matches a 10 digit North America NANP number with optional extension. Spaces, dashes and periods are accepted delimiters.

"^(\\(?\\d\\d\\d\\)?)( |-|\\.)?\\d\\d\\d( |-|\\.)?\\d{4,4}(( |-|\\.)?[ext\\.]+ ?\\d+)?$"

.jar isn't executable. Instantiate classes or make call to any static method.

EDIT: Add Main-Class entry while creating a JAR.

>p.mf (content of p.mf)

Main-Class: pk.Test

>Test.java

package pk;
public class Test{
  public static void main(String []args){
    System.out.println("Hello from Test");
  }
}

Use Process class and it's methods,

public class Exec
{
   public static void main(String []args) throws Exception
    {
        Process ps=Runtime.getRuntime().exec(new String[]{"java","-jar","A.jar"});
        ps.waitFor();
        java.io.InputStream is=ps.getInputStream();
        byte b[]=new byte[is.available()];
        is.read(b,0,b.length);
        System.out.println(new String(b));
    }
}

if you want to filter the tuples you can use on this way:

select distinct (case a > b then (a,b) else (b,a) end) from pairs

the good stuff is you don't have to use group by.

There is a more efficient way of doing this in Windows 7. SETX is installed by default and supports connecting to other systems.

To modify a remote system's global environment variables, you would use

setx /m /s HOSTNAME-GOES-HERE VariableNameGoesHere VariableValueGoesHere

This does not require restarting Windows Explorer.

I use this method for bubble sorting

public static int[] bubbleSort (int[] a) {
    int n = a.length;
    int j = 0;
    boolean swap = true;
    while (swap) {
        swap = false;
        for (int j = 1; j < n; j++) {
            if (a[j-1] > a[j]) {
                j = a[j-1];
                a[j-1] = a[j];
                a[j] = j;
                swap = true;
            }
        }
        n = n - 1;
    }
    return a;
}//end bubbleSort

If you offer cbind a set of arguments all of whom are vectors, you will get not a dataframe, but rather a matrix, in this case an all character matrix. They have different features. You can get a dataframe if some of your arguments remain dataframes, Try:

merger <- cbind(Date =as.character(Date),
             weather1[ , c("High", "Low", "Avg..High", "Avg.Low")] , 
             ScnMov =sale$Scanned.Movement[a] )

ISO-8859-1 is a legacy standards from back in 1980s. It can only represent 256 characters so only suitable for some languages in western world. Even for many supported languages, some characters are missing. If you create a text file in this encoding and try copy/paste some Chinese characters, you will see weird results. So in other words, don't use it. Unicode has taken over the world and UTF-8 is pretty much the standards these days unless you have some legacy reasons (like HTTP headers which needs to compatible with everything).

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }
        });
    }
}

I read all the above comments but didn't see anyone pointed to the main difference between Group By and Distinct apart from the aggregation bit.

Distinct returns all the rows then de-duplicates them whereas Group By de-deduplicate the rows as they're read by the algorithm one by one.

This means they can produce different results!

For example, the below codes generate different results:

SELECT distinct ROW_NUMBER() OVER (ORDER BY Name), Name FROM NamesTable

 SELECT ROW_NUMBER() OVER (ORDER BY Name), Name FROM NamesTable
GROUP BY Name

If there are 10 names in the table where 1 of which is a duplicate of another then the first query returns 10 rows whereas the second query returns 9 rows.

The reason is what I said above so they can behave differently!

Important behaviour that has not yet been mentioned:

Programmatically setting the checked attribute, does not fire the change event of the checkbox.

See for yourself in this fiddle:
http://jsfiddle.net/fjaeger/L9z9t04p/4/

(Fiddle tested in Chrome 46, Firefox 41 and IE 11)

The click() method

Some day you might find yourself writing code, which relies on the event being fired. To make sure the event fires, call the click() method of the checkbox element, like this:

document.getElementById('checkbox').click();

However, this toggles the checked status of the checkbox, instead of specifically setting it to true or false. Remember that the change event should only fire, when the checked attribute actually changes.

It also applies to the jQuery way: setting the attribute using prop or attr, does not fire the change event.

Setting checked to a specific value

You could test the checked attribute, before calling the click() method. Example:

function toggle(checked) {
  var elm = document.getElementById('checkbox');
  if (checked != elm.checked) {
    elm.click();
  }
}

Read more about the click method here:

For all the pythonian zealots out there I'm sure Johan Cleeze would approve of your dogmatism ;). I'm leaving this answer keep demeriting it It actually makes me more confidant. Leave a comment you chickens!

For python 3.6

class SomeClass:

    def attr_list1(self, should_print=False):

        for k in self.__dict__.keys():
            v = self.__dict__.__getitem__(k)
            if should_print:
                print(f"attr: {k}    value: {v}")

    def attr_list(self, should_print=False):

        b = [(k, v) for k, v in self.__dict__.items()]
        if should_print:
            [print(f"attr: {a[0]}    value: {a[1]}") for a in b]
        return b

You can pass all similar type values in the function while calling it. In the function definition put a array so that all the passed values can be collected in that array. e.g. .

static void demo (String ... stringArray) {
  your code goes here where read the array stringArray
}

pgrep -f <your process name> | xargs kill -9

This will kill the your process service. In my case it is

pgrep -f python | xargs kill -9

To add one year to todays date use the following:

$oneYearOn = date('Y-m-d',strtotime(date("Y-m-d", mktime()) . " + 365 day"));

For the other examples you must initialize $StartingDate with a timestamp value for example:

$StartingDate = mktime();  // todays date as a timestamp

Try this

$newEndingDate = date("Y-m-d", strtotime(date("Y-m-d", strtotime($StaringDate)) . " + 365 day"));

or

$newEndingDate = date("Y-m-d", strtotime(date("Y-m-d", strtotime($StaringDate)) . " + 1 year"));

Another solution is to use stat_count() when dealing with discrete variables (and stat_bin() with continuous ones).

ggplot(data = df, aes(x = x)) +
geom_bar(stat = "count") + 
stat_count(geom = "text", colour = "white", size = 3.5,
aes(label = ..count..),position=position_stack(vjust=0.5))

Here is a simple python code example of Recursive, Top-down, Bottom-up approach for Fibonacci series:

Recursive: O(2ⁿ)

def fib_recursive(n):
    if n == 1 or n == 2:
        return 1
    else:
        return fib_recursive(n-1) + fib_recursive(n-2)


print(fib_recursive(40))

Top-down: O(n) Efficient for larger input

def fib_memoize_or_top_down(n, mem):
    if mem[n] is not 0:
        return mem[n]
    else:
        mem[n] = fib_memoize_or_top_down(n-1, mem) + fib_memoize_or_top_down(n-2, mem)
        return mem[n]


n = 40
mem = [0] * (n+1)
mem[1] = 1
mem[2] = 1
print(fib_memoize_or_top_down(n, mem))

Bottom-up: O(n) For simplicity and small input sizes

def fib_bottom_up(n):
    mem = [0] * (n+1)
    mem[1] = 1
    mem[2] = 1
    if n == 1 or n == 2:
        return 1

    for i in range(3, n+1):
        mem[i] = mem[i-1] + mem[i-2]

    return mem[n]


print(fib_bottom_up(40))

Old unsecured way:

Follow 3 simple steps to secure API/Secret key (Old answer)

We can use Gradle to secure the API key or Secret key.

1. gradle.properties (Project properties) : Create variable with key.

GoolgeAPIKey = "Your API/Secret Key"

2. build.gradle (Module: app) : Set variable in build.gradle to access it in activity or fragment. Add below code to buildTypes {}.

buildTypes.each {
    it.buildConfigField 'String', 'GoogleSecAPIKEY', GoolgeAPIKey
}

3. Access it in Activity/Fragment by app's BuildConfig :

BuildConfig.GoogleSecAPIKEY

Update :

The above solution is helpful in the open source project to commit over Git. (Thanks to David Rawson and riyaz-ali for your comment).

As per the Matthew and Pablo Cegarra comments the above way is not secure and Decompiler will allow someone to view the BuildConfig with our secret keys.

Solution :

We can use NDK to Secure API Keys. We can store keys in the native C/C++ class and access them in our Java classes.

Please follow this blog to secure API keys using NDK.

I've been verifying calls in the same manner - I believe it is the right way to do it.

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => mo.Id == 5 && mo.description == "test")
  ), Times.Once());

If your lambda expression becomes unwieldy, you could create a function that takes MyObject as input and outputs true/false...

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => MyObjectFunc(mo))
  ), Times.Once());

private bool MyObjectFunc(MyObject myObject)
{
  return myObject.Id == 5 && myObject.description == "test";
}

Also, be aware of a bug with Mock where the error message states that the method was called multiple times when it wasn't called at all. They might have fixed it by now - but if you see that message you might consider verifying that the method was actually called.

EDIT: Here is an example of calling verify multiple times for those scenarios where you want to verify that you call a function for each object in a list (for example).

foreach (var item in myList)
  mockRepository.Verify(mr => mr.Update(
    It.Is<MyObject>(i => i.Id == item.Id && i.LastUpdated == item.LastUpdated),
    Times.Once());

Same approach for setup...

foreach (var item in myList) {
  var stuff = ... // some result specific to the item
  this.mockRepository
    .Setup(mr => mr.GetStuff(item.itemId))
    .Returns(stuff);
}

So each time GetStuff is called for that itemId, it will return stuff specific to that item. Alternatively, you could use a function that takes itemId as input and returns stuff.

this.mockRepository
    .Setup(mr => mr.GetStuff(It.IsAny<int>()))
    .Returns((int id) => SomeFunctionThatReturnsStuff(id));

One other method I saw on a blog some time back (Phil Haack perhaps?) had setup returning from some kind of dequeue object - each time the function was called it would pull an item from a queue.

import shutil

shutil.rmtree('/folder_name')

Standard Library Reference: shutil.rmtree.

By design, rmtree fails on folder trees containing read-only files. If you want the folder to be deleted regardless of whether it contains read-only files, then use

shutil.rmtree('/folder_name', ignore_errors=True)

Here's how

String details = "Hello \"world\"!";
details = details.replace("\"","\\\"");
System.out.println(details);               // Hello \"world\"!

Note that strings are immutable, thus it is not sufficient to simply do details.replace("\"","\\\""). You must reassign the variable details to the resulting string.

Using

details = details.replaceAll("\"","&quote;");

instead, results in

Hello &quote;world&quote;!

In SUSE Linux Enterprise Server (SLES) and openSUSE the global one is located at /etc/vimrc.

To edit it, simply do vi /etc/vimrc.

Basically it contains all the attributes which describe the object in question. It can be used to alter or read the attributes. Quoting from the documentation for __dict__

A dictionary or other mapping object used to store an object's (writable) attributes.

Remember, everything is an object in Python. When I say everything, I mean everything like functions, classes, objects etc (Ya you read it right, classes. Classes are also objects). For example:

def func():
    pass

func.temp = 1

print(func.__dict__)

class TempClass:
    a = 1
    def temp_function(self):
        pass

print(TempClass.__dict__)

will output

{'temp': 1}
{'__module__': '__main__', 
 'a': 1, 
 'temp_function': <function TempClass.temp_function at 0x10a3a2950>, 
 '__dict__': <attribute '__dict__' of 'TempClass' objects>, 
 '__weakref__': <attribute '__weakref__' of 'TempClass' objects>, 
 '__doc__': None}

You can use the re library

Assuming that you are able to load your full txt-file. You then define a list of unwanted nicknames and then substitute them with an empty string "".

# Delete unwanted characters
import re

# Read, then decode for py2 compat.
path_to_file = 'data/nicknames.txt'
text = open(path_to_file, 'rb').read().decode(encoding='utf-8')

# Define unwanted nicknames and substitute them
unwanted_nickname_list = ['SourDough']
text = re.sub("|".join(unwanted_nickname_list), "", text)

If you do not want to handle separate properties for each possible argument, I suggest you'd use:

<arg line="${args}"/>

You can check if the property is not set using a specific target with an unless attribute and inside do:

<input message="Type the desired command line arguments:" addProperty="args"/>

Putting it all together gives:

<target name="run" depends="compile, input-runargs" description="run the project">
  <!-- You can use exec here, depending on your needs -->
  <java classname="Main">
    <arg line="${args}"/>
  </java>
</target>
<target name="input-runargs" unless="args" description="prompts for command line arguments if necessary">
  <input addProperty="args" message="Type the desired command line arguments:"/>
</target>

You can use it as follows:

ant
ant run
ant run -Dargs='--help'

The first two commands will prompt for the command-line arguments, whereas the latter won't.

The problem here, as explained in other comments, is that the pointer is being dereference without being properly initialized. Operating systems like Linux keep the lowest addresses (eg first 32MB: 0x00_0000 -0x200_0000) out of the virtual address space of a process. This is done because dereferencing zeroed non-initialized pointers is a common mistake, like in this case. So when this type of mistake happens, instead of actually reading a random variable that happens to be at address 0x0 (but not the memory address the pointer would be intended for if initialized properly), the pointer would be reading from a memory address outside of the process's virtual address space. This causes a page fault, which results in a segmentation fault, and a signal is sent to the process to kill it. That's why you are getting the access violation error.

Warnings are annoying. As mentioned in other answers, you can suppress them using:

import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)

But if you want to handle them one by one and you are managing a bigger codebase, it will be difficult to find the line of code which is causing the warning. Since warnings unlike errors don't come with code traceback. In order to trace warnings like errors, you can write this at the top of the code:

import warnings
warnings.filterwarnings("error")

But if the codebase is bigger and it is importing bunch of other libraries/packages, then all sort of warnings will start to be raised as errors. In order to raise only certain type of warnings (in your case, its FutureWarning) as error, you can write:

import warnings
warnings.simplefilter(action='error', category=FutureWarning)

See if this example provides any clarification. Basically you configure a set of routes and include partial templates based on the route. Setting ng-view in your main index.html allows you to inject those partial views.

The config portion looks like this:

  .config(['$routeProvider', function($routeProvider) {
    $routeProvider
      .when('/', {controller:'ListCtrl', templateUrl:'list.html'})
      .otherwise({redirectTo:'/'});
  }])

The point of entry for injecting the partial view into your main template is:

<div class="container" ng-view=""></div>

Your default alignment is probably 4 bytes. Either the 30 byte element got 32, or the structure as a whole was rounded up to the next 4 byte interval.

Just give you some idea how other databases solve this problem. DolphinDB also has built-in support for pivoting and the sql looks much more intuitive and neat. It is as simple as specifying the key column (Store), pivoting column (Week), and the calculated metric (sum(xCount)).

//prepare a 10-million-row table
n=10000000
t=table(rand(100, n) + 1 as Store, rand(54, n) + 1 as Week, rand(100, n) + 1 as xCount)

//use pivot clause to generate a pivoted table pivot_t
pivot_t = select sum(xCount) from t pivot by Store, Week

DolphinDB is a columnar high performance database. The calculation in the demo costs as low as 546 ms on a dell xps laptop (i7 cpu). To get more details, please refer to online DolphinDB manual https://www.dolphindb.com/help/index.html?pivotby.html

Since momentjs has no control over javascript date object I found a work around to this.

const currentTime = new Date();    _x000D_
const convertTime = moment(currentTime).tz(timezone).format("YYYY-MM-DD HH:mm:ss");_x000D_
const convertTimeObject = new Date(convertTime);

This will give you a javascript date object with the converted time

Using pip with git+ to clone a repository can be extremely slow (test with https://github.com/django/django@stable/1.6.x for example, it will take a few minutes). The fastest thing I've found, which works with GitHub and BitBucket, is:

pip install https://github.com/user/repository/archive/branch.zip

which becomes for Django master:

pip install https://github.com/django/django/archive/master.zip

for Django stable/1.7.x:

pip install https://github.com/django/django/archive/stable/1.7.x.zip

With BitBucket it's about the same predictable pattern:

pip install https://bitbucket.org/izi/django-admin-tools/get/default.zip

Here, the master branch is generally named default. This will make your requirements.txt installing much faster.

Some other answers mention variations required when placing the package to be installed into your requirements.txt. Note that with this archive syntax, the leading -e and trailing #egg=blah-blah are not required, and you can just simply paste the URL, so your requirements.txt looks like:

https://github.com/user/repository/archive/branch.zip

Simply put all the images thumbnails inside a row/col divs like this:

<div class="row text-center">
 <div class="col-12">
  # your images here...
 </div>
</div>

and everything will work fine!

Insert the item currently at oldIndex to be at newIndex and then remove the original instance.

list.Insert(newIndex, list[oldIndex]);
if (newIndex <= oldIndex) ++oldIndex;
list.RemoveAt(oldIndex);

You have to take into account that the index of the item you want to remove may change due to the insertion.

When you are reading the file, have you considered reading it line by line? This would allow you to check if your line contains the file as your are reading, and you could then perform whatever logic you needed based on that?

Scanner scanner = new Scanner("Student.txt");
String currentLine;

while((currentLine = scanner.readLine()) != null)
{
    if(currentLine.indexOf("Your String"))
    {
         //Perform logic
    }
}

You could use a variable to hold the line number, or you could also have a boolean indicating if you have passed the line that contains your string:

Scanner scanner = new Scanner("Student.txt");
String currentLine;
int lineNumber = 0;
Boolean passedLine = false;
while((currentLine = scanner.readLine()) != null)
{
    if(currentLine.indexOf("Your String"))
    {
         //Do task
         passedLine = true;
    }
    if(passedLine)
    {
       //Do other task after passing the line.
    }
    lineNumber++;
}

You cal also do this

SELECT  SUM(amnt) `value`,DATE_FORMAT(dtrg,'%m-%y') AS label FROM rentpay GROUP BY YEAR(dtrg) DESC, MONTH(dtrg) DESC LIMIT 12

to order by year and month. Lets say you want to order from this year and this month all the way back to 12 month

Your resource methods won't get hit, so their headers will never get set. The reason is that there is what's called a preflight request before the actual request, which is an OPTIONS request. So the error comes from the fact that the preflight request doesn't produce the necessary headers.

For RESTeasy, you should use CorsFilter. You can see here for some example how to configure it. This filter will handle the preflight request. So you can remove all those headers you have in your resource methods.

See Also:

• HTTP access control (CORS)

The Content-Security-Policy meta-tag allows you to reduce the risk of XSS attacks by allowing you to define where resources can be loaded from, preventing browsers from loading data from any other locations. This makes it harder for an attacker to inject malicious code into your site.

I banged my head against a brick wall trying to figure out why I was getting CSP errors one after another, and there didn't seem to be any concise, clear instructions on just how does it work. So here's my attempt at explaining some points of CSP briefly, mostly concentrating on the things I found hard to solve.

For brevity I won’t write the full tag in each sample. Instead I'll only show the content property, so a sample that says content="default-src 'self'" means this:

<meta http-equiv="Content-Security-Policy" content="default-src 'self'">

1. How can I allow multiple sources?

You can simply list your sources after a directive as a space-separated list:

content="default-src 'self' https://example.com/js/"

Note that there are no quotes around parameters other than the special ones, like 'self'. Also, there's no colon (:) after the directive. Just the directive, then a space-separated list of parameters.

Everything below the specified parameters is implicitly allowed. That means that in the example above these would be valid sources:

https://example.com/js/file.js
https://example.com/js/subdir/anotherfile.js

These, however, would not be valid:

http://example.com/js/file.js
^^^^ wrong protocol

https://example.com/file.js
                   ^^ above the specified path

2. How can I use different directives? What do they each do?

The most common directives are:

• default-src the default policy for loading javascript, images, CSS, fonts, AJAX requests, etc
• script-src defines valid sources for javascript files
• style-src defines valid sources for css files
• img-src defines valid sources for images
• connect-src defines valid targets for to XMLHttpRequest (AJAX), WebSockets or EventSource. If a connection attempt is made to a host that's not allowed here, the browser will emulate a 400 error

There are others, but these are the ones you're most likely to need.

3. How can I use multiple directives?

You define all your directives inside one meta-tag by terminating them with a semicolon (;):

content="default-src 'self' https://example.com/js/; style-src 'self'"

4. How can I handle ports?

Everything but the default ports needs to be allowed explicitly by adding the port number or an asterisk after the allowed domain:

content="default-src 'self' https://ajax.googleapis.com http://example.com:123/free/stuff/"

The above would result in:

https://ajax.googleapis.com:123
                           ^^^^ Not ok, wrong port

https://ajax.googleapis.com - OK

http://example.com/free/stuff/file.js
                 ^^ Not ok, only the port 123 is allowed

http://example.com:123/free/stuff/file.js - OK

As I mentioned, you can also use an asterisk to explicitly allow all ports:

content="default-src example.com:*"

5. How can I handle different protocols?

By default, only standard protocols are allowed. For example to allow WebSockets ws:// you will have to allow it explicitly:

content="default-src 'self'; connect-src ws:; style-src 'self'"
                                         ^^^ web Sockets are now allowed on all domains and ports.

6. How can I allow the file protocol file://?

If you'll try to define it as such it won’t work. Instead, you'll allow it with the filesystem parameter:

content="default-src filesystem"

7. How can I use inline scripts and style definitions?

Unless explicitly allowed, you can't use inline style definitions, code inside <script> tags or in tag properties like onclick. You allow them like so:

content="script-src 'unsafe-inline'; style-src 'unsafe-inline'"

You'll also have to explicitly allow inline, base64 encoded images:

content="img-src data:"

8. How can I allow eval()?

I'm sure many people would say that you don't, since 'eval is evil' and the most likely cause for the impending end of the world. Those people would be wrong. Sure, you can definitely punch major holes into your site's security with eval, but it has perfectly valid use cases. You just have to be smart about using it. You allow it like so:

content="script-src 'unsafe-eval'"

9. What exactly does 'self' mean?

You might take 'self' to mean localhost, local filesystem, or anything on the same host. It doesn't mean any of those. It means sources that have the same scheme (protocol), same host, and same port as the file the content policy is defined in. Serving your site over HTTP? No https for you then, unless you define it explicitly.

I've used 'self' in most examples as it usually makes sense to include it, but it's by no means mandatory. Leave it out if you don't need it.

But hang on a minute! Can't I just use content="default-src *" and be done with it?

No. In addition to the obvious security vulnerabilities, this also won’t work as you'd expect. Even though some docs claim it allows anything, that's not true. It doesn't allow inlining or evals, so to really, really make your site extra vulnerable, you would use this:

content="default-src * 'unsafe-inline' 'unsafe-eval'"

... but I trust you won’t.

To invoke a dry run:

make -n

This will show what make is attempting to do.

What is row?

Either of these could be correct.

1) I assume that you capture your ajax response in a javascript variable 'row'. If that is the case, this would hold true.

var result=row.split('|');
    alert(result[2]);

otherwise

2) Use this where $(row) is a jQuery object.

var result=$(row).val().split('|');
    alert(result[2]);

[As mentioned in the other answer, you may have to use $(row).val() or $(row).text() or $(row).html() etc. depending on what $(row) is.]

I like to do this with sed. In you case:

for x in DET01-*.dat; do
    echo $x | sed -r 's/DET01-ABC-(.+)\.dat/mv -v "\0" "DET01-XYZ-\1.dat"/'
done | sh -e

It is best to omit the "sh -e" part first to see what will be executed.

Brute force code to answer your question:

DataTable dt = new DataTable();

//for each of your properties
dt.Columns.Add("PropertyOne", typeof(string));

foreach(Entity entity in entities)
{
  DataRow row = dt.NewRow();

  //foreach of your properties
  row["PropertyOne"] = entity.PropertyOne;

  dt.Rows.Add(row);
}

DataSet ds = new DataSet();
ds.Tables.Add(dt);
return ds;

Now for the actual question. Why would you want to do this? As mentioned earlier, you can bind directly to an object list. Maybe a reporting tool that only takes datasets?

You use input.files property. It's a collection of File objects and each file has a name property:

onmouseout="for (var i = 0; i < this.files.length; i++) alert(this.files[i].name);"

You can use ndiff in the difflib module to do this. It has all the information necessary to convert one string into another string.

A simple example:

import difflib

cases=[('afrykanerskojezyczny', 'afrykanerskojezycznym'),
       ('afrykanerskojezyczni', 'nieafrykanerskojezyczni'),
       ('afrykanerskojezycznym', 'afrykanerskojezyczny'),
       ('nieafrykanerskojezyczni', 'afrykanerskojezyczni'),
       ('nieafrynerskojezyczni', 'afrykanerskojzyczni'),
       ('abcdefg','xac')] 

for a,b in cases:     
    print('{} => {}'.format(a,b))  
    for i,s in enumerate(difflib.ndiff(a, b)):
        if s[0]==' ': continue
        elif s[0]=='-':
            print(u'Delete "{}" from position {}'.format(s[-1],i))
        elif s[0]=='+':
            print(u'Add "{}" to position {}'.format(s[-1],i))    
    print()      

prints:

afrykanerskojezyczny => afrykanerskojezycznym
Add "m" to position 20

afrykanerskojezyczni => nieafrykanerskojezyczni
Add "n" to position 0
Add "i" to position 1
Add "e" to position 2

afrykanerskojezycznym => afrykanerskojezyczny
Delete "m" from position 20

nieafrykanerskojezyczni => afrykanerskojezyczni
Delete "n" from position 0
Delete "i" from position 1
Delete "e" from position 2

nieafrynerskojezyczni => afrykanerskojzyczni
Delete "n" from position 0
Delete "i" from position 1
Delete "e" from position 2
Add "k" to position 7
Add "a" to position 8
Delete "e" from position 16

abcdefg => xac
Add "x" to position 0
Delete "b" from position 2
Delete "d" from position 4
Delete "e" from position 5
Delete "f" from position 6
Delete "g" from position 7

I think I found an easier way (for me anyway). Locate your javaw.exe file (either by searching for it or just where you installed it), then drag the javaw.exe file onto the eclipse.exe file and it will use it.

After discussion posting updated answer:

Option Explicit
Sub test()

    Dim wk As String, yr As String
    Dim fname As String, fpath As String
    Dim owb As Workbook

    With Application
        .DisplayAlerts = False
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    wk = ComboBox1.Value
    yr = ComboBox2.Value
    fname = yr & "W" & wk
    fpath = "C:\Documents and Settings\jammil\Desktop\AutoFinance\ProjectControl\Data"

    On Error GoTo ErrorHandler
    Set owb = Application.Workbooks.Open(fpath & "\" & fname)

    'Do Some Stuff

    With owb
        .SaveAs fpath & Format(Date, "yyyymm") & "DB" & ".xlsx", 51
        .Close
    End With

    With Application
        .DisplayAlerts = True
        .ScreenUpdating = True
        .EnableEvents = True
    End With

Exit Sub
ErrorHandler: If MsgBox("This File Does Not Exist!", vbRetryCancel) = vbCancel Then

Else: Call Clear

End Sub

Error Handling:

You could try something like this to catch a specific error:

    On Error Resume Next
    Set owb = Application.Workbooks.Open(fpath & "\" & fname)
    If Err.Number = 1004 Then
    GoTo FileNotFound
    Else
    End If

    ...
    Exit Sub
    FileNotFound: If MsgBox("This File Does Not Exist!", vbRetryCancel) = vbCancel Then

    Else: Call Clear

Try this:

!pip install category_encoders
import category_encoders as ce

categorical_columns = [...the list of names of the columns you want to one-hot-encode ...]
encoder = ce.OneHotEncoder(cols=categorical_columns, use_cat_names=True)
df_train_encoded = encoder.fit_transform(df_train_small)

df_encoded.head()

The resulting dataframe df_train_encoded is the same as the original, but the categorical features are now replaced with their one-hot-encoded versions.

Have you checked that those classes are present in the CSS? Are you using twitter-bootstrap-rails gem? It still uses Bootstrap 2.X version and those are Bootstrap 3.X classes. The CSS grid changed since.

You can switch to the bootstrap3 branch of the gem https://github.com/seyhunak/twitter-bootstrap-rails/tree/bootstrap3 or include boostrap in an alternative way.

Why are you doing this?

 reader = csv.reader(open(filepath, "rU"))

The docs are pretty clear that you must do this:

with open(filepath, "rb") as src:
    reader= csv.reader( src )

The mode must be "rb" to read.

http://docs.python.org/library/csv.html#csv.reader

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

df['Col1']=df['Col1'].apply(lambda x: '{0:0>5}'.format(x))

The 5 is the number of total digits.

My suggestion does not come from Terminal; however, this is a much easier way.

For .bat files, you can run them through Wine. Use this video to help you install it: https://www.youtube.com/watch?v=DkS8i_blVCA. This video will explain how to install, setup and use Wine. It is as simple as opening the .bat file in Wine itself, and it will run just as it would on Windows.

Through this, you can also run .exe files, as well .sh files.

This is much simpler than trying to work out all kinds of terminal code.

strtok() divides the string into tokens. i.e. starting from any one of the delimiter to next one would be your one token. In your case, the starting token will be from "-" and end with next space " ". Then next token will start from " " and end with ",". Here you get "This" as output. Similarly the rest of the string gets split into tokens from space to space and finally ending the last token on "."
