In a previous project I found that changing from *-imports to specific imports reduced compilation time by half (from about 10 minutes to about 5 minutes). The *-import makes the compiler search each of the packages listed for a class matching the one you used. While this time can be small, it adds up for large projects.

A side affect of the *-import was that developers would copy and paste common import lines rather than think about what they needed.

You can use one of these methods to convert number to an ASCII / Unicode / UTF-16 character:

You can use these methods convert the value of the specified 32-bit signed integer to its Unicode character:

char c = (char)65;
char c = Convert.ToChar(65); 

Also, ASCII.GetString decodes a range of bytes from a byte array into a string:

string s = Encoding.ASCII.GetString(new byte[]{ 65 });

Keep in mind that, ASCIIEncoding does not provide error detection. Any byte greater than hexadecimal 0x7F is decoded as the Unicode question mark ("?").

you can use zscore to analyze the data in column C and D for outliers, where zscore is the series - series.mean / series.std(). Use apply too create a user defined function for difference between C and D creating a new resulting dataframe. Apply uses the group result set.

The above answers no longer work with ES 6.2.2 because of Strict Content-Type Checking for Elasticsearch REST Requests. The curl command which I ended up using is this:

Difference between Paint() and Repaint() method

Paint():

This method holds instructions to paint this component. Actually, in Swing, you should change paintComponent() instead of paint(), as paint calls paintBorder(), paintComponent() and paintChildren(). You shouldn't call this method directly, you should call repaint() instead.

Repaint():

This method can't be overridden. It controls the update() -> paint() cycle. You should call this method to get a component to repaint itself. If you have done anything to change the look of the component, but not its size ( like changing color, animating, etc. ) then call this method.

In Spring all source files are inside src/main/java. Similarly, the resources are generally kept inside src/main/resources. So keep your spring configuration file inside resources folder.

Make sure you have the ClassPath entry for your files inside src/main/resources as well.

In .classpath check for the following 2 lines. If they are missing add them.

<classpathentry path="src/main/java" kind="src"/>
<classpathentry path="src/main/resources" kind="src" />

So, if you have everything in place the below code should work.

ApplicationContext ctx = new ClassPathXmlApplicationContext("Spring-Module.xml");

When starting the Python interpreter in the terminal/command line you may also see a line like:

Python 2.7.2 (default, Jun 12 2011, 14:24:46) [MSC v.1500 64 bit (AMD64)] on win32

Where [MSC v.1500 64 bit (AMD64)] means 64-bit Python. Works for my particular setup.

For visualization and summary of PyTorch models, tensorboardX can also can be utilized.

There are three types of variables:

• Instance variables: are always initialized
• Static variables: are always initialized
• Local variables: must be initialized before use

The default values for instance and static variables are the same and depends on the type:

• Object type (String, Integer, Boolean and others): initialized with null
• Primitive types:
  • byte, short, int, long: 0
  • float, double: 0.0
  • boolean: false
  • char: '\u0000'

An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.

Once the array is created all of its elements are assiged with the default type value. For example:

private boolean[] list; // default value is null

private Boolean[] list; // default value is null

once is initialized:

private boolean[] list = new boolean[10]; // all ten elements are assigned to false

private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)

A nice approach would be to start up your processes and services running them in the background and use the wait [n ...] command at the end of your script. In bash, the wait command forces the current process to:

Wait for each specified process and return its termination status. If n is not given, all currently active child processes are waited for, and the return status is zero.

I got this idea from Sébastien Pujadas' start script for his elk build.

Taking from the original question, your start-all.sh would look something like this...

 #!/usr/bin/env bash
 /etc/init.d/hadoop-hdfs-namenode start &
 /etc/init.d/hadoop-hdfs-datanode start &
 /etc/init.d/hadoop-hdfs-secondarynamenode start &
 /etc/init.d/hadoop-0.20-mapreduce-tasktracker start &
 sudo -u hdfs hadoop fs -chmod 777 /
 /etc/init.d/hadoop-0.20-mapreduce-jobtracker start &
 wait

var accounting = [];
var employees = {};

for(var i in someData) {

    var item = someData[i];

   accounting.push({ 
        "firstName" : item.firstName,
        "lastName"  : item.lastName,
        "age"       : item.age 
    });
}

employees.accounting = accounting;

I know this question has been answered but I also see there is another way missing which I would like to cover it.There are multiple ways to achieve this.

1- innerHTML

document.getElementById("ShowButton").innerHTML = 'Show Filter';

You can insert HTML into this. But the disadvantage of this method is, it has cross site security attacks. So for adding text, its better to avoid this for security reasons.

2- innerText

document.getElementById("ShowButton").innerText = 'Show Filter';

This will also achieve the result but its heavy under the hood as it requires some layout system information, due to which the performance decreases. Unlike innerHTML, you cannot insert the HTML tags with this. Check Performance Here

3- textContent

document.getElementById("ShowButton").textContent = 'Show Filter';

This will also achieve the same result but it doesn't have security issues like innerHTML as it doesn't parse HTML like innerText. Besides, it is also light due to which performance increases.

So if a text has to be added like above, then its better to use textContent.

Delete table-striped Its overriding your attempts to change row color.

Then do this In css

   tr:nth-child(odd) {
    background-color: lightskyblue;
    }

   tr:nth-child(even) {
    background-color: lightpink;
    }

    th {
       background-color: lightseagreen;
    }

Confusing messages

These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".

The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.

The real ffmpeg vs the fake one

For a while both Libav and FFmpeg separately developed their own version of ffmpeg.

Libav then renamed their bizarro ffmpeg to avconv to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv instead of their counterfeit version of ffmpeg. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.

This message was removed upstream when the fake "ffmpeg" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.

In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1. Unfortunately the new "deprecated" message has caused additional user confusion.

Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg is back in the repositories again.

libav vs Libav

To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.

How to tell the difference

If you are using avconv then you are using Libav. If you are using ffmpeg you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.

Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg or avconv and viewing the console output.

If you want to use the real ffmpeg

Ubuntu 15.04 "Vivid Vervet" or newer

The real ffmpeg is in the repository, so you can install it with:

apt-get install ffmpeg

For older Ubuntu versions

Your options are:

• Download a recent Linux build of ffmpeg,
• follow a step-by-step guide to compile ffmpeg,
• or use Doug McMahon's PPA (for Ubuntu 14.04 LTS "Trusty Tahr")

These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.

Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg from the repository.

I can't fault any of the answers here for the OP accepted one of them as resolving their problem. However, I found them flawed in one respect. When you output the result of the assignment to the variable, it contains numerous blank lines, not just the sought after answer. Example:

PS C:\brh> [datetime](Get-ItemProperty -Path .\deploy.ps1 -Name LastWriteTime).LastWriteTime

Friday, December 12, 2014 2:33:09 PM



PS C:\brh> 

I'm a fan of two things in code, succinctness and correctness. brianary has the right of it for succinctness with a tip of the hat to Roger Lipscombe but both miss correctness due to the extra lines in the result. Here's what I think the OP was looking for since it's what got me over the finish line.

PS C:\brh> (ls .\deploy.ps1).LastWriteTime.DateTime
Friday, December 12, 2014 2:33:09 PM

PS C:\brh> 

Note the lack of extra lines, only the one that PowerShell uses to separate prompts. Now this can be assigned to a variable for comparison or, as in my case, stored in a file for reading and comparison in a later session.

To get a compact list without dependencies simply use

You just need to install Java. It did work after installing Java version 8, using this command : sudo apt install openjdk-8-jre-headless

In case of WSS 3.0 recently I experienced same issue. It was because of column that was accessed from code was not present in the wss list.

Instead of writing a function to do this check, you should just be able to use this expression:

(number < 0)

Javascript will evaluate this expression by first trying to convert the left hand side to a number value before checking if it's less than zero, which seems to be what you wanted.

Specifications and details

The behavior for x < y is specified in §11.8.1 The Less-than Operator (<), which uses §11.8.5 The Abstract Relational Comparison Algorithm.

The situation is a lot different if both x and y are strings, but since the right hand side is already a number in (number < 0), the comparison will attempt to convert the left hand side to a number to be compared numerically. If the left hand side can not be converted to a number, the result is false.

Do note that this may give different results when compared to your regex-based approach, but depending on what is it that you're trying to do, it may end up doing the right thing anyway.

• "-0" < 0 is false, which is consistent with the fact that -0 < 0 is also false (see: signed zero).
• "-Infinity" < 0 is true (infinity is acknowledged)
• "-1e0" < 0 is true (scientific notation literals are accepted)
• "-0x1" < 0 is true (hexadecimal literals are accepted)
• " -1 " < 0 is true (some forms of whitespaces are allowed)

For each of the above example, the regex method would evaluate to the contrary (true instead of false and vice versa).

Appendix 1: Conditional operator ?:

It should also be said that statements of this form:

if (someCondition) {
   return valueForTrue;
} else {
   return valueForFalse;
}

can be refactored to use the ternary/conditional ?: operator (§11.12) to simply:

return (someCondition) ? valueForTrue : valueForFalse;

Idiomatic usage of ?: can make the code more concise and readable.

Appendix 2: Type conversion functions

Javascript has functions that you can call to perform various type conversions.

Something like the following:

if (someVariable) {
   return true;
} else {
   return false;
}

Can be refactored using the ?: operator to:

return (someVariable ? true : false);

But you can also further simplify this to:

return Boolean(someVariable);

This calls Boolean as a function (§15.16.1) to perform the desired type conversion. You can similarly call Number as a function (§15.17.1) to perform a conversion to number.

In MVVM (wich makes a lot of things a lot easier - you should try it) you would have two properties in your ViewModel Text that is bound to your TextBox and you would have an ICommand property Apply (or similar) that is bound to the button:

<Button Command="Apply">Apply</Button>

The ICommand interface has a Method CanExecute that is where you return true if (!string.IsNullOrWhiteSpace(this.Text). The rest is done by WPF for you (enabling/disabling, executing the actual command on click).

The linked article explains it in detail.

So this error is occurring because you have a value in your source for the AppID column that is not valid for your AppID column in the destination.

Some possible examples:

• You're trying to insert a 10 character value into an 8 character field.
• You're trying to insert a value larger than 127 into a tinyint field.
• You're trying to insert the value 6.4578 into a decimal(5,1) field.

SSIS is governed by metadata, and it expects that you've set up your inputs and outputs properly such that the acceptable values for both are within the same range.

You can always use an attribute selector. The selector itself would look something like:

a[data-item-id=stand-out]

Array.prototype.map() index:

One can access the index Array.prototype.map() via the second argument of the callback function. Here is an example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
_x000D_
const map = array.map((x, index) => {_x000D_
  console.log(index);_x000D_
  return x + index;_x000D_
});_x000D_
_x000D_
console.log(map);

Other arguments of Array.prototype.map():

• The third argument of the callback function exposes the array on which map was called upon
• The second argument of Array.map() is a object which will be the this value for the callback function. Keep in mind that you have to use the regular function keyword in order to declare the callback since an arrow function doesn't have its own binding to the this keyword.

For example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
const thisObj = {prop1: 1}_x000D_
_x000D_
_x000D_
const map = array.map( function (x, index, array) {_x000D_
  console.log(array);_x000D_
  console.log(this)_x000D_
}, thisObj);

This with no warnings!

    HashMap<String, String> meMap=new HashMap<String, String>();
    meMap.put("Color1","Red");
    meMap.put("Color2","Blue");
    meMap.put("Color3","Green");
    meMap.put("Color4","White");

    for (Object o : meMap.keySet()) {
        Toast.makeText(getBaseContext(), meMap.get(o.toString()),
                Toast.LENGTH_SHORT).show();
    }

There is no way to completely avoid reverse engineering of an APK. To protect application assets, resources, you can use encryption.

• Encryption will make harder to use it without decryption.choosing some strong encryption algorithm will make cracking harder.
• Adding some spoof code into your main logic to make more harder for cracking.
• If you can write your critical logic in any native language and that surely make harder for decompile.
• Using any third party security frameworks like Quixxi

I'm offering some benchmarking results comparing the most prominent approaches presented so far, namely @bobince's findnth() (based on str.split()) vs. @tgamblin's or @Mark Byers' find_nth() (based on str.find()). I will also compare with a C extension (_find_nth.so) to see how fast we can go. Here is find_nth.py:

def findnth(haystack, needle, n):
    parts= haystack.split(needle, n+1)
    if len(parts)<=n+1:
        return -1
    return len(haystack)-len(parts[-1])-len(needle)

def find_nth(s, x, n=0, overlap=False):
    l = 1 if overlap else len(x)
    i = -l
    for c in xrange(n + 1):
        i = s.find(x, i + l)
        if i < 0:
            break
    return i

Of course, performance matters most if the string is large, so suppose we want to find the 1000001st newline ('\n') in a 1.3 GB file called 'bigfile'. To save memory, we would like to work on an mmap.mmap object representation of the file:

In [1]: import _find_nth, find_nth, mmap

In [2]: f = open('bigfile', 'r')

In [3]: mm = mmap.mmap(f.fileno(), 0, access=mmap.ACCESS_READ)

There is already the first problem with findnth(), since mmap.mmap objects don't support split(). So we actually have to copy the whole file into memory:

In [4]: %time s = mm[:]
CPU times: user 813 ms, sys: 3.25 s, total: 4.06 s
Wall time: 17.7 s

Ouch! Fortunately s still fits in the 4 GB of memory of my Macbook Air, so let's benchmark findnth():

In [5]: %timeit find_nth.findnth(s, '\n', 1000000)
1 loops, best of 3: 29.9 s per loop

Clearly a terrible performance. Let's see how the approach based on str.find() does:

In [6]: %timeit find_nth.find_nth(s, '\n', 1000000)
1 loops, best of 3: 774 ms per loop

Much better! Clearly, findnth()'s problem is that it is forced to copy the string during split(), which is already the second time we copied the 1.3 GB of data around after s = mm[:]. Here comes in the second advantage of find_nth(): We can use it on mm directly, such that zero copies of the file are required:

In [7]: %timeit find_nth.find_nth(mm, '\n', 1000000)
1 loops, best of 3: 1.21 s per loop

There appears to be a small performance penalty operating on mm vs. s, but this illustrates that find_nth() can get us an answer in 1.2 s compared to findnth's total of 47 s.

I found no cases where the str.find() based approach was significantly worse than the str.split() based approach, so at this point, I would argue that @tgamblin's or @Mark Byers' answer should be accepted instead of @bobince's.

In my testing, the version of find_nth() above was the fastest pure Python solution I could come up with (very similar to @Mark Byers' version). Let's see how much better we can do with a C extension module. Here is _find_nthmodule.c:

#include <Python.h>
#include <string.h>

off_t _find_nth(const char *buf, size_t l, char c, int n) {
    off_t i;
    for (i = 0; i < l; ++i) {
        if (buf[i] == c && n-- == 0) {
            return i;
        }
    }
    return -1;
}

off_t _find_nth2(const char *buf, size_t l, char c, int n) {
    const char *b = buf - 1;
    do {
        b = memchr(b + 1, c, l);
        if (!b) return -1;
    } while (n--);
    return b - buf;
}

        return NULL;    
    }
}

static PyMethodDef methods[] = {
    {"find_nth", py_find_nth, METH_VARARGS, ""},
    {"find_nth2", py_find_nth2, METH_VARARGS, ""},
    {0}
};

PyMODINIT_FUNC init_find_nth(void) {
    Py_InitModule("_find_nth", methods);
}

Here is the setup.py file:

from distutils.core import setup, Extension
module = Extension('_find_nth', sources=['_find_nthmodule.c'])
setup(ext_modules=[module])

Install as usual with python setup.py install. The C code plays at an advantage here since it is limited to finding single characters, but let's see how fast this is:

In [8]: %timeit _find_nth.find_nth(mm, '\n', 1000000)
1 loops, best of 3: 218 ms per loop

In [9]: %timeit _find_nth.find_nth(s, '\n', 1000000)
1 loops, best of 3: 216 ms per loop

In [10]: %timeit _find_nth.find_nth2(mm, '\n', 1000000)
1 loops, best of 3: 307 ms per loop

In [11]: %timeit _find_nth.find_nth2(s, '\n', 1000000)
1 loops, best of 3: 304 ms per loop

Clearly quite a bit faster still. Interestingly, there is no difference on the C level between the in-memory and mmapped cases. It is also interesting to see that _find_nth2(), which is based on string.h's memchr() library function, loses out against the straightforward implementation in _find_nth(): The additional "optimizations" in memchr() are apparently backfiring...

In conclusion, the implementation in findnth() (based on str.split()) is really a bad idea, since (a) it performs terribly for larger strings due to the required copying, and (b) it doesn't work on mmap.mmap objects at all. The implementation in find_nth() (based on str.find()) should be preferred in all circumstances (and therefore be the accepted answer to this question).

There is still quite a bit of room for improvement, since the C extension ran almost a factor of 4 faster than the pure Python code, indicating that there might be a case for a dedicated Python library function.

Changed if file not exists. Create empty file.

For those who are not using model binding, who are extracting each parameter from the Request.Form, who are sure the input text will cause no harm, there is another way. Not a great solution but it will do the job.

From client side, encode it as uri then send it.
e.g:

encodeURIComponent($("#MsgBody").val());  

From server side, accept it and decode it as uri.
e.g:

string temp = !string.IsNullOrEmpty(HttpContext.Current.Request.Form["MsgBody"]) ?
System.Web.HttpUtility.UrlDecode(HttpContext.Current.Request.Form["MsgBody"]) : 
null;  

or

string temp = !string.IsNullOrEmpty(HttpContext.Current.Request.Form["MsgBody"]) ?
System.Uri.UnescapeDataString(HttpContext.Current.Request.Form["MsgBody"]) : 
null; 

please look for the differences between UrlDecode and UnescapeDataString

Some handy script:

hour = df['assess_time'].dt.hour.values[0]

There is a function in scipy named scipy.signal.find_peaks_cwt which sounds like is suitable for your needs, however I don't have experience with it so I cannot recommend..

http://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.find_peaks_cwt.html

Use the zipfile module. To extract a file from a URL, you'll need to wrap the result of a urlopen call in a BytesIO object. This is because the result of a web request returned by urlopen doesn't support seeking:

from urllib.request import urlopen

from io import BytesIO
from zipfile import ZipFile

zip_url = 'http://example.com/my_file.zip'

with urlopen(zip_url) as f:
    with BytesIO(f.read()) as b, ZipFile(b) as myzipfile:
        foofile = myzipfile.open('foo.txt')
        print(foofile.read())

If you already have the file downloaded locally, you don't need BytesIO, just open it in binary mode and pass to ZipFile directly:

from zipfile import ZipFile

zip_filename = 'my_file.zip'

with open(zip_filename, 'rb') as f:
    with ZipFile(f) as myzipfile:
        foofile = myzipfile.open('foo.txt')
        print(foofile.read().decode('utf-8'))

Again, note that you have to open the file in binary ('rb') mode, not as text or you'll get a zipfile.BadZipFile: File is not a zip file error.

It's good practice to use all these things as context managers with the with statement, so that they'll be closed properly.

You can write your query like so:

SELECT * FROM MyTable WHERE (A LIKE '%text1%' OR A LIKE '%text2%')

The % is a wildcard, meaning that it searches for all rows where column A contains either text1 or text2

A couple more command-line mailer programs:

• mailsend
• Mail Alert Simple Mailer

Both support SSL too.

You can create your own method, passing throught the array and the value you want removed:

function removeItem(arr, item){
 return arr.filter(f => f !== item)
}

Then you can call this with:

ary = removeItem(ary, 'seven');

As explained in below code: Execute below queries and verify yourself.

CREATE TABLE `table_name` (
  `id` int(11) NOT NULL auto_increment,
  `name` varchar(255) NOT NULL,
  `address` varchar(255) NOT NULL,
  `tele` varchar(255) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB;

Insert a record:

INSERT INTO table_name (name, address, tele)
SELECT * FROM (SELECT 'Nazir', 'Kolkata', '033') AS tmp
WHERE NOT EXISTS (
    SELECT name FROM table_name WHERE name = 'Nazir'
) LIMIT 1;
Query OK, 1 row affected (0.00 sec)
Records: 1 Duplicates: 0 Warnings: 0

SELECT * FROM `table_name`;

+----+--------+-----------+------+
| id | name   | address   | tele |
+----+--------+-----------+------+
|  1 | Nazir  | Kolkata   | 033  |
+----+--------+-----------+------+

Now, try to insert the same record again:

INSERT INTO table_name (name, address, tele)
SELECT * FROM (SELECT 'Nazir', 'Kolkata', '033') AS tmp
WHERE NOT EXISTS (
    SELECT name FROM table_name WHERE name = 'Nazir'
) LIMIT 1;

Query OK, 0 rows affected (0.00 sec)
Records: 0  Duplicates: 0  Warnings: 0

| id | name   | address   | tele |
+----+--------+-----------+------+
|  1 | Nazir  | Kolkata   | 033  |
+----+--------+-----------+------+

Insert a different record:

INSERT INTO table_name (name, address, tele)
SELECT * FROM (SELECT 'Santosh', 'Kestopur', '044') AS tmp
WHERE NOT EXISTS (
    SELECT name FROM table_name WHERE name = 'Santosh'
) LIMIT 1;

Query OK, 1 row affected (0.00 sec)
Records: 1 Duplicates: 0 Warnings: 0

SELECT * FROM `table_name`;

+----+--------+-----------+------+
| id | name   | address   | tele |

In Python2,

d1={'a':1,'b':2}
d2={'a':10,'c':3}

d1 overrides d2:

dict(d2,**d1)
# {'a': 1, 'c': 3, 'b': 2}

d2 overrides d1:

dict(d1,**d2)
# {'a': 10, 'c': 3, 'b': 2}

This behavior is not just a fluke of implementation; it is guaranteed in the documentation:

If a key is specified both in the positional argument and as a keyword argument, the value associated with the keyword is retained in the dictionary.

Python 3:

urllib.parse.quote_plus(string, safe='', encoding=None, errors=None)

The page sizes are looking different in your PDF because the images were originally set to different DPI (even if images are identical HxW in pixels). The good news is - it's only a display issue - and can be fixed easily.

An image with a higher DPI value would display smaller in a PDF (displays at the 'print-size' of the image). To avoid this, open each image in an image editor like GIMP or Photoshop. Open relevant image print control dialog box and set a suitable uniform DPI info for all the images. Remake the PDF with these new images. If in the new PDF images are too big - redo the DPI setting for each to a higher value. If in the new PDF pages are too small to read on-screen without zooming, again - redo DPI adjustment, this time put a lower DPI value. Ideally, 150 DPI should be good enough for images of 2500X2500 pixel - on a 17 inch monitor set to 1366x768 resolution.

BTW, the PDF file shall print each page at the specified DPI of that page. If all images are same DPI, you'll get a uniform printing.

Hope this helps :)

Its so simple just use this

header("location:javascript://history.go(-1)");

Its working fine for me

Use :

$(PROJECT_DIR)/Project name/PrefixHeader.pch

"put" need "get" (to ensure no duplicate key).
So directly do a "put",
and if there was a previous value, then do an addition:

Map map = new HashMap ();

MutableInt newValue = new MutableInt (1); // default = inc
MutableInt oldValue = map.put (key, newValue);
if (oldValue != null) {
  newValue.add(oldValue); // old + inc
}

If count starts at 0, then add 1: (or any others values...)

Map map = new HashMap ();

MutableInt newValue = new MutableInt (0); // default
MutableInt oldValue = map.put (key, newValue);
if (oldValue != null) {
  newValue.setValue(oldValue + 1); // old + inc
}

Notice : This code is not thread safe. Use it to build then use the map, not to concurrently update it.

Optimization : In a loop, keep old value to become the new value of next loop.

Map map = new HashMap ();
final int defaut = 0;
final int inc = 1;

MutableInt oldValue = new MutableInt (default);
while(true) {
  MutableInt newValue = oldValue;

  oldValue = map.put (key, newValue); // insert or...
  if (oldValue != null) {
    newValue.setValue(oldValue + inc); // ...update

    oldValue.setValue(default); // reuse
  } else
    oldValue = new MutableInt (default); // renew
  }
}

this one also gives the no.of lines in a file.

a=open('filename.txt','r')
l=a.read()
count=l.splitlines()
print(len(count))

However, I got curious to what each class contained and when I try to open one of the classes in the jar file, it tells me that I need a source file.

A jar file is basically a zip file containing .class files and potentially other resources (and metadata about the jar itself). It's hard to compare C to Java really, as Java byte code maintains a lot more metadata than most binary formats - but the class file is compiled code instead of source code.

If you either open the jar file with a zip utility or run jar xf foo.jar you can extract the files from it, and have a look at them. Note that you don't need a jar file to run Java code - classloaders can load class data directly from the file system, or from URLs, as well as from jar files.

You should add providers: [AngularFirestore] in app.module.ts.

@NgModule({
  imports: [
    BrowserModule,
    AngularFireModule.initializeApp(environment.firebase)
  ],
  declarations: [ AppComponent ],
  providers: [AngularFirestore],
  bootstrap: [ AppComponent ]
})
export class AppModule {}

You can use res.render() or res.redirect() method to redirect to another page using node.js express

Eg:

var bodyParser = require('body-parser');
var express = require('express');
var navigator = require('web-midi-api');
var app = express();

app.use(express.static(__dirname + '/'));
app.use(bodyParser.urlencoded({extend:true}));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.set('views', __dirname);

app.get('/', function(req, res){
    res.render("index");
});

//This reponds a post request for the login page
app.post('/login', function (req, res) {
    console.log("Got a POST request for the login");
    var data = {
        "email": req.body.email,
        "password": req.body.password
    };

    console.log(data);

    //Data insertion code
    var MongoClient = require('mongodb').MongoClient;
    var url = "mongodb://localhost:27017/";

    MongoClient.connect(url, function(err, db) {
        if (err) throw err;
        var dbo = db.db("college");
        var query = { email: data.email };
        dbo.collection("user").find(query).toArray(function(err, result) {
            if (err) throw err;
            console.log(result);
            if(result[0].password == data.password)


 res.redirect('dashboard.html');
            else


 res.redirect('login-error.html');
            db.close();
        });
    });

});


// This responds a POST request for the add user
app.post('/insert', function (req, res) {
    console.log("Got a POST request for the add user");

    var data = {
        "first_name" : req.body.firstName,
        "second_name" : req.body.secondName,
        "organization" : req.body.organization,
        "email": req.body.email,
        "mobile" : req.body.mobile,
    };

    console.log(data);

    **res.render('success.html',{email:data.email,password:data.password});**

});


//make sure that Service Workers are supported.
if (navigator.serviceWorker) {
    navigator.serviceWorker.register('service-worker.js', {scope: '/'})
        .then(function (registration) {
            console.log(registration);
        })
        .catch(function (e) {
            console.error(e);
        })
} else {
    console.log('Service Worker is not supported in this browser.');
}


// TODO add service worker code here
if ('serviceWorker' in navigator) {
    navigator.serviceWorker
        .register('service-worker.js')
        .then(function() { console.log('Service Worker Registered'); });
}

var server = app.listen(63342, function () {

    var host = server.address().host;
    var port = server.address().port;

    console.log("Example app listening at http://localhost:%s", port)
});

Here in the login section, If the email and password matches in the database then the site is directed to dashbaord.html otherwise we will show page-error.html using res.redirect() method. Also you can use res.render() to render a page in node.js

If you already have the dropdownlist available in a variable, this is what works for me:

$("option:selected", myVar).text()

The other answers on this question helped me, but ultimately the jQuery forum thread $(this + "option:selected").attr("rel") option selected is not working in IE helped the most.

Update: fixed the above link

It's an array, so you're looking for Count to test for contents.

I'd recommend

$foo.count -gt 0

The "why" of this is related to how PSH handles comparison of collection objects

var objToJson = { };
objToJson.response = response;
response.write(JSON.stringify(objToJson));

If you alert(JSON.stringify(objToJson)) you will get {"response":"value"}

I did this many years back on 2003 or possibly 97, yikes!

If I recall you need to use one of the subcommands above tied to a timer. You cannot operate on the db with any connections or forms open.

So you do something about closing all forms, and kick off the timer as the last running method. (which will in turn call the compact operation once everything closes)

If you haven't figured this out I could dig through my archives and pull it up.

If you want to implement that yourself, the OAuth 2.0 flow for Web Server Applications is documented at https://developers.google.com/accounts/docs/OAuth2WebServer, in particular you should check the section about using a refresh token:

https://developers.google.com/accounts/docs/OAuth2WebServer#refresh

Use the Mod % (modulus) operator

if ($x % 6 == 0) return 1;


function nearest_multiple_of_6($x) {
    if ($x % 6 == 0) return $x;    

    return (($x / 6) + 1) * 6;
}

A tested one-liner:

int number = ((NSNumber*)[dict objectForKey:@"integer"]).intValue;

This is a simple way to extract the date:

import pandas as pd

d='2015-01-08 22:44:09' 
date=pd.to_datetime(d).date()
print(date)

Add a contextmenu to your form and then assign it in the control's properties under ContextMenuStrip. Hope this helps :).

Hope this helps:

ContextMenu cm = new ContextMenu();
cm.MenuItems.Add("Item 1");
cm.MenuItems.Add("Item 2");

pictureBox1.ContextMenu = cm;

One solution is to put them inside <center>, like this:

<center>
<a href="http//www.google.com">Search</a>
<a href="Contact Us">Contact Us</a>
</center>

I've also created a jsfiddle for you: https://jsfiddle.net/9acgLf8e/

Another way to do this would be to add this line to the assembly info of the web application:

// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(Watch = true)]

Similar to Shriek's.

Although os.rename() and shutil.move() will both rename files, the command that is closest to the Unix mv command is shutil.move(). The difference is that os.rename() doesn't work if the source and destination are on different disks, while shutil.move() doesn't care what disk the files are on.

In your css add folllowing

[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
    display: none !important;
 }

And then in you code you can add ng-cloak directive. For example,

<div ng-cloak>
   Welcome {{data.name}}
</div>

Thats it!

private void dataGridView1_DataBindingComplete(object sender DataGridViewBindingCompleteEventArgs e)
{
    foreach (DataGridViewRow row in dataGridView1.Rows)
    {
        if (Convert.ToInt32(row.Cells["balaceAmount"].Value) == 0)
        {
            row.DefaultCellStyle.BackColor = Color.Yellow;
        }
        else
        {
            row.DefaultCellStyle.BackColor = Color.White;
        }
    }
}

You can't have a link to SCSS File in your HTML page.You have to compile it down to CSS First. No there are lots of video tutorials you might want to check out. Lynda provides great video tutorials on SASS. there are also free screencasts you can google...

For official documentation visit this site http://sass-lang.com/documentation/file.SASS_REFERENCE.html And why have you chosen notepad to write Sass?? you can easily download some free text editors for better code handling.

Yes, both will give you deferred execution.

The difference is that IQueryable<T> is the interface that allows LINQ-to-SQL (LINQ.-to-anything really) to work. So if you further refine your query on an IQueryable<T>, that query will be executed in the database, if possible.

For the IEnumerable<T> case, it will be LINQ-to-object, meaning that all objects matching the original query will have to be loaded into memory from the database.

In code:

IQueryable<Customer> custs = ...;
// Later on...
var goldCustomers = custs.Where(c => c.IsGold);

That code will execute SQL to only select gold customers. The following code, on the other hand, will execute the original query in the database, then filtering out the non-gold customers in the memory:

IEnumerable<Customer> custs = ...;
// Later on...
var goldCustomers = custs.Where(c => c.IsGold);

This is quite an important difference, and working on IQueryable<T> can in many cases save you from returning too many rows from the database. Another prime example is doing paging: If you use Take and Skip on IQueryable, you will only get the number of rows requested; doing that on an IEnumerable<T> will cause all of your rows to be loaded in memory.

Well, now you know there is a problem, the next step is to figure out what exactly the error is, what happens when you compile and run this?:

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    FILE *file;
    file = fopen("TestFile1.txt", "r");
    if (file == NULL) {
      perror("Error");
    } else {
      fclose(file);
    }
}

Its quite easy on computer a you don't need to do anything just make sure both system are on same network if its not internet access(for this you need static ip). Okay now on computer b go to start menu find configuration under oracle folder click Net Configuration Assistant under that folder when window pop up click Local net configuration option it must be third option.

Now click add and click next in next screen it will ask service name here you need to add oracle global database name of computer A(Normally I use oracle86 for my installation) now click next next screen choose protocol normally its tcp click next in host name enter computer A's name you can found that in my computer properties. Click next don't change port untill you have changed that in Computer A click next and choose test connection now here you can check your connection working or not if the error is username and password not correct then click login credential button and fill correct username and password. If its saying unable to reach computer ot target not found than you must add exception in firewall for 1521 port or just disable firewall on computer A.

When creating a custom rating bar that displays a solid gradient line running on a SeekBar-like track, rather than stars, I also encountered a problem related to the vertical centering of the background (track drawable). This is the flawed drawable code I used originally (which generated the problem), as suggested by Android developer and other StackOverflow entries:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@android:id/background"
        android:drawable="@drawable/seekbar_track"/>
    <item android:id="@android:id/secondaryProgress">
        <scale
            android:drawable="@drawable/seekbar_progress2"
            android:scaleWidth="100%" />
    </item>

    <item android:id="@android:id/progress" >
        <clip android:clipOrientation="horizontal" android:gravity="left" >
            <shape>
                <gradient
                    android:startColor="@color/ratingbar_bg_start"
                    android:centerColor="@color/ratingbar_bg_center"
                    android:centerX="0.5"
                    android:endColor="@color/ratingbar_bg_end"
                    android:angle="0"
                    />
            </shape>
        </clip>
    </item>    

 </layer-list>

The problem here is the first item, which relates to the background of the custom RatingBar. Many entries will tell you to set the layout_minHeight feature to some large value to avoid a vertical spatial disconnect between the thumb and its track. This was not the solution for me - when viewed on a tablet, the background was still drawing to its smaller phone-based size - so the track was consistently positioned well above the center of the RatingBar track. The solution is to remove this entry in the RatingBar drawable, so it now looks like this:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/secondaryProgress">
        <scale
            android:drawable="@drawable/seekbar_progress2"
            android:scaleWidth="100%" />
    </item>

    <item android:id="@android:id/progress" >
        <clip android:clipOrientation="horizontal" android:gravity="left" >
            <shape>
                <gradient
                    android:startColor="@color/ratingbar_bg_start"
                    android:centerColor="@color/ratingbar_bg_center"
                    android:centerX="0.5"
                    android:endColor="@color/ratingbar_bg_end"
                    android:angle="0"
                    />
            </shape>
        </clip>
    </item>    

 </layer-list>

Then, in the style definition of the custom RatingBar, set the layout_background to the the track drawable. Mine looks like this:

<style name="styleRatingBar" parent="@android:style/Widget.RatingBar">
    <item name="android:indeterminateOnly">false</item>
    <item name="android:background">@drawable/seekbar_track</item>
    <item name="android:progressDrawable">@drawable/abratingbar</item>
    <item name="android:thumb">@drawable/abseekbar_thumb</item>
    <item name="android:minHeight">@dimen/base_29dp</item>
    <item name="android:maxHeight">@dimen/base_29dp</item>
    <item name="android:layout_marginLeft">@dimen/base_10dp</item>
    <item name="android:layout_marginRight">@dimen/base_10dp</item>
    <item name="android:layout_marginTop">@dimen/base_10dp</item>
    <item name="android:layout_marginBottom">@dimen/base_10dp</item>
    <item name="android:scaleType">fitXY</item>
</style>

(Previously, the background setting here was undefined.).

This is the entry in my layout, which uses both the style and the drawables:

<RatingBar
    android:id="@+id/ratingbar_vote"
    style="@style/styleRatingBar"
    android:hint="@string/ratingbar_vote"
    android:contentDescription="@string/ratingbar_vote"
    android:numStars="5"
    android:rating="5"
    android:stepSize="1"
    android:layout_width="match_parent"
    android:layout_height="@dimen/base_29dp"
    android:layout_marginLeft="@dimen/base_120dp"
    android:layout_gravity="bottom|right" />

So, to summarize, do not set the background (track) feature in your custom RatingBar drawable, set it in the layout_background feature of your custom RatingBar style. This ensures the track is always vertically centered in a horizontal RatingBar. (Remember, in this custom RatingBar, instead of using stars or other isolated images as the rating, I'm using a gradient line that "grows" or "shrinks" horizontally to display the rating - this rating line uses a SeekBar-like thumb running on a SeekBar-like "track".)

You can find the list of duplicate names using the following aggregate pipeline:

• Group all the records having similar name.
• Match those groups having records greater than 1.
• Then group again to project all the duplicate names as an array.

The Code:

db.collection.aggregate([
{$group:{"_id":"$name","name":{$first:"$name"},"count":{$sum:1}}},
{$match:{"count":{$gt:1}}},
{$project:{"name":1,"_id":0}},
{$group:{"_id":null,"duplicateNames":{$push:"$name"}}},
{$project:{"_id":0,"duplicateNames":1}}
])

o/p:

{ "duplicateNames" : [ "ksqn291", "ksqn29123213Test" ] }

A common issue you might experience when working on a Laravel application is the exception:

RuntimeException No application encryption key has been specified.

You'll often run into this when you pull down an existing Laravel application, where you copy the .env.example file to .env but don't set a value for the APP_KEY variable.

At the command line, issue the following Artisan command to generate a key:

php artisan key:generate

This will generate a random key for APP_KEY, After completion of .env edit please enter this command in your terminal for clear cache:php artisan config:cache

Also, If you are using the PHP's default web server (eg. php artisan serve) you need to restart the server changing your .env file values. now you will not get to see this error message.

Well, first, you need to actually define a function before you can run it (and it doesn't need to be called main). For instance:

class Example(object):
    def run(self):
        print "Hello, world!"

if __name__ == '__main__':
    Example().run()

You don't need to use a class, though - if all you want to do is run some code, just put it inside a function and call the function, or just put it in the if block:

def main():
    print "Hello, world!"

if __name__ == '__main__':
    main()

or

if __name__ == '__main__':
    print "Hello, world!"

You can #include <cstdint>. It's part of C++-standard since 2011.

You can use Environment.CurrentDirectory to get the current directory, and FileSystemInfo.FullPath to get the full path to any location. So, fully qualify both the current directory and the file in question, and then check whether the full file name starts with the directory name - if it does, just take the appropriate substring based on the directory name's length.

Here's some sample code:

using System;
using System.IO;

class Program
{
    public static void Main(string[] args)
    {
        string currentDir = Environment.CurrentDirectory;
        DirectoryInfo directory = new DirectoryInfo(currentDir);
        FileInfo file = new FileInfo(args[0]);

        string fullDirectory = directory.FullName;
        string fullFile = file.FullName;

        if (!fullFile.StartsWith(fullDirectory))
        {
            Console.WriteLine("Unable to make relative path");
        }
        else
        {
            // The +1 is to avoid the directory separator
            Console.WriteLine("Relative path: {0}",
                              fullFile.Substring(fullDirectory.Length+1));
        }
    }
}

I'm not saying it's the most robust thing in the world (symlinks could probably confuse it) but it's probably okay if this is just a tool you'll be using occasionally.

In case that you need to turn on and off the listener multiple times, you can create a function with boolean parameter

function switchListen(_switch) {
    if (_switch) {
      $scope.$on("onViewUpdated", this.callMe);
    } else {
      $rootScope.$$listeners.onViewUpdated = [];
    }
}

You can do it with cut:

cut -d " " -f 3- input_filename > output_filename

Explanation:

• cut: invoke the cut command
• -d " ": use a single space as the delimiter (cut uses TAB by default)
• -f: specify fields to keep
• 3-: all the fields starting with field 3
• input_filename: use this file as the input
• > output_filename: write the output to this file.

Alternatively, you can do it with awk:

awk '{$1=""; $2=""; sub("  ", " "); print}' input_filename > output_filename

Explanation:

• awk: invoke the awk command
• $1=""; $2="";: set field 1 and 2 to the empty string
• sub(...);: clean up the output fields because fields 1 & 2 will still be delimited by " "
• print: print the modified line
• input_filename > output_filename: same as above.

Object does not have forEach, it belongs to Array prototype. If you want to iterate through each key-value pair in the object and take the values. You can do this:

Object.keys(a).forEach(function (key){
    console.log(a[key]);
});

Usage note: For an object v = {"cat":"large", "dog": "small", "bird": "tiny"};, Object.keys(v) gives you an array of the keys so you get ["cat","dog","bird"]

The only way I am able to make it work is by:

docker run -it -e USER=$USER -v /etc/passwd:/etc/passwd -v `pwd`:/siem mono bash
su - magnus

So I have to both specify $USER environment variable as well a point the /etc/passwd file. In this way, I can compile in /siem folder and retain ownership of files there not as root.

A better way is:

$("#element").val(null);

<script type="text/javascript">
function showDiv(toggle){
document.getElementById(toggle).style.display = 'block';
}
</script>

<input type="button" name="answer" onclick="showDiv('toggle')">Show</input>

<div id="toggle" style="display:none">Hello</div>

If you want to do a periodic task, use a ScheduledExecutorService. Specifically ScheduledExecutorService.scheduleAtFixedRate

The code:

Runnable helloRunnable = new Runnable() {
    public void run() {
        System.out.println("Hello world");
    }
};

ScheduledExecutorService executor = Executors.newScheduledThreadPool(1);
executor.scheduleAtFixedRate(helloRunnable, 0, 3, TimeUnit.SECONDS);

Use the .clone() method on your List. It will return a shallow copy, meaning that it will contain pointers to the same objects, so you won't have to copy the list. Then just use Collections.

Ergo,

Collections.reverse(list.clone());

If you are using a List and don't have access to clone() you can use subList():

List<?> shallowCopy = list.subList(0, list.size());
Collections.reverse(shallowCopy);

The parameter has this syntax:

{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}

So your example of '1.2-2' means:

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

TL;DR

SELECT json_agg(t) FROM t

for a JSON array of objects, and

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

for a JSON object of arrays.

List of objects

This section describes how to generate a JSON array of objects, with each row being converted to a single object. The result looks like this:

[{"a":1,"b":"value1"},{"a":2,"b":"value2"},{"a":3,"b":"value3"}]

9.3 and up

The json_agg function produces this result out of the box. It automatically figures out how to convert its input into JSON and aggregates it into an array.

SELECT json_agg(t) FROM t

There is no jsonb (introduced in 9.4) version of json_agg. You can either aggregate the rows into an array and then convert them:

SELECT to_jsonb(array_agg(t)) FROM t

or combine json_agg with a cast:

SELECT json_agg(t)::jsonb FROM t

My testing suggests that aggregating them into an array first is a little faster. I suspect that this is because the cast has to parse the entire JSON result.

9.2

9.2 does not have the json_agg or to_json functions, so you need to use the older array_to_json:

SELECT array_to_json(array_agg(t)) FROM t

You can optionally include a row_to_json call in the query:

SELECT array_to_json(array_agg(row_to_json(t))) FROM t

This converts each row to a JSON object, aggregates the JSON objects as an array, and then converts the array to a JSON array.

I wasn't able to discern any significant performance difference between the two.

Object of lists

This section describes how to generate a JSON object, with each key being a column in the table and each value being an array of the values of the column. It's the result that looks like this:

{"a":[1,2,3], "b":["value1","value2","value3"]}

9.5 and up

We can leverage the json_build_object function:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

You can also aggregate the columns, creating a single row, and then convert that into an object:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

Note that aliasing the arrays is absolutely required to ensure that the object has the desired names.

Which one is clearer is a matter of opinion. If using the json_build_object function, I highly recommend putting one key/value pair on a line to improve readability.

You could also use array_agg in place of json_agg, but my testing indicates that json_agg is slightly faster.

There is no jsonb version of the json_build_object function. You can aggregate into a single row and convert:

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Unlike the other queries for this kind of result, array_agg seems to be a little faster when using to_jsonb. I suspect this is due to overhead parsing and validating the JSON result of json_agg.

Or you can use an explicit cast:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )::jsonb
FROM t

The to_jsonb version allows you to avoid the cast and is faster, according to my testing; again, I suspect this is due to overhead of parsing and validating the result.

9.4 and 9.3

The json_build_object function was new to 9.5, so you have to aggregate and convert to an object in previous versions:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

or

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

depending on whether you want json or jsonb.

(9.3 does not have jsonb.)

9.2

In 9.2, not even to_json exists. You must use row_to_json:

SELECT row_to_json(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Documentation

Find the documentation for the JSON functions in JSON functions.

json_agg is on the aggregate functions page.

Design

If performance is important, ensure you benchmark your queries against your own schema and data, rather than trust my testing.

Whether it's a good design or not really depends on your specific application. In terms of maintainability, I don't see any particular problem. It simplifies your app code and means there's less to maintain in that portion of the app. If PG can give you exactly the result you need out of the box, the only reason I can think of to not use it would be performance considerations. Don't reinvent the wheel and all.

Nulls

Aggregate functions typically give back NULL when they operate over zero rows. If this is a possibility, you might want to use COALESCE to avoid them. A couple of examples:

SELECT COALESCE(json_agg(t), '[]'::json) FROM t

Or

SELECT to_jsonb(COALESCE(array_agg(t), ARRAY[]::t[])) FROM t

_{Credit to Hannes Landeholm for pointing this out}

I think there is no need to specify

'http://localhost:8080`" 

in the URI part.. because. if you specify it, You'll have to change it manually for every environment.

Only

"/restws/json/product/get" also works

Very basic way to implement looping in cmd programming using labels

@echo off
SET /A "index=1"
SET /A "count=5"
:while
if %index% leq %count% (
   echo The value of index is %index%
   SET /A "index=index + 1"
   goto :while
)

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Edit

Further explanation: How does Python compare string and int?

On my linux system to get just the filenames

diff -q /dir1 /dir2|cut -f2 -d' '

var responseData = //Fetch Data
string jsonData = JsonConvert.SerializeObject(responseData, Formatting.None);
System.IO.File.WriteAllText(Server.MapPath("~/JsonData/jsondata.txt"), jsonData);

Since 2011, if you can change function1, do so, like this:

#include <functional>
#include <cstdio>

using namespace std;

class aClass
{
public:
    void aTest(int a, int b)
    {
        printf("%d + %d = %d", a, b, a + b);
    }
};

template <typename Callable>
void function1(Callable f)
{
    f(1, 1);
}

void test(int a,int b)
{
    printf("%d - %d = %d", a , b , a - b);
}

int main()
{
    aClass obj;

    // Free function
    function1(&test);

    // Bound member function
    using namespace std::placeholders;
    function1(std::bind(&aClass::aTest, obj, _1, _2));

    // Lambda
    function1([&](int a, int b) {
        obj.aTest(a, b);
    });
}

(live demo)

Notice also that I fixed your broken object definition (aClass a(); declares a function).

(Swift 4.2 Xcode 11) Simple to use Extension:-

extension Double {
    func round(to places: Int) -> Double {
        let divisor = pow(10.0, Double(places))
        return (self * divisor).rounded() / divisor
    }
}

Use:-

if let distanceDb = Double(strDistance) {
   cell.lblDistance.text = "\(distanceDb.round(to:2)) km"
}

PDOStatement::fetch returns a row from the result set. The parameter PDO::FETCH_ASSOC tells PDO to return the result as an associative array.

The array keys will match your column names. If your table contains columns 'email' and 'password', the array will be structured like:

Array
(
    [email] => '[email protected]'
    [password] => 'yourpassword'
)

To read data from the 'email' column, do:

$user['email'];

and for 'password':

$user['password'];

Duplicate tag parameters are not allowed in HTML. What you could do, is VALUE="1,2010". But you would have to parse the value on the server.

A functional language (ideally) allows you to write a mathematical function, i.e. a function that takes n arguments and returns a value. If the program is executed, this function is logically evaluated as needed.¹

A procedural language, on the other hand, performs a series of sequential steps. (There's a way of transforming sequential logic into functional logic called continuation passing style.)

As a consequence, a purely functional program always yields the same value for an input, and the order of evaluation is not well-defined; which means that uncertain values like user input or random values are hard to model in purely functional languages.

¹ As everything else in this answer, that’s a generalisation. This property, evaluating a computation when its result is needed rather than sequentially where it’s called, is known as “laziness”. Not all functional languages are actually universally lazy, nor is laziness restricted to functional programming. Rather, the description given here provides a “mental framework” to think about different programming styles that are not distinct and opposite categories but rather fluid ideas.

I'm surprised nobody has mentioned the simplest version:

\d

This will match any digit. If your regular expression engine is Unicode-aware, this means it will match anything that's defined as a digit in any language, not just the Arabic numerals 0-9.

There's no need to put it in [square brackets] to define it as a character class, as one of the other answers did; \d works fine by itself.

Since it's not anchored with ^ or $, it will match any subset of the string, so if the string contains at least one digit, this will match.

And there's no need for the added complexity of +, since the goal is just to determine whether there's at least one digit. If there's at least one digit, this will match; and it will do so with a minimum of overhead.

I would write the code like this:

def search_book(request):
    form = SearchForm(request.POST or None)
    if request.method == "POST" and form.is_valid():
        stitle = form.cleaned_data['title']
        sauthor = form.cleaned_data['author']
        scategory = form.cleaned_data['category']
        return HttpResponseRedirect('/thanks/')
    return render_to_response("books/create.html", {
        "form": form,
    }, context_instance=RequestContext(request))

Pretty much like the documentation.

In above code, you don't pass the kml data to your mapView anywhere in your code, as far as I can see. To display the route, you should parse the kml data i.e. via SAX parser, then display the route markers on the map.

See the code below for an example, but it's not complete though - just for you as a reference and get some idea.

This is a simple bean I use to hold the route information I will be parsing.

package com.myapp.android.model.navigation;

import java.util.ArrayList;
import java.util.Iterator;


public class NavigationDataSet { 

private ArrayList<Placemark> placemarks = new ArrayList<Placemark>();
private Placemark currentPlacemark;
private Placemark routePlacemark;

public String toString() {
    String s= "";
    for (Iterator<Placemark> iter=placemarks.iterator();iter.hasNext();) {
        Placemark p = (Placemark)iter.next();
        s += p.getTitle() + "\n" + p.getDescription() + "\n\n";
    }
    return s;
}

public void addCurrentPlacemark() {
    placemarks.add(currentPlacemark);
}

public ArrayList<Placemark> getPlacemarks() {
    return placemarks;
}

public void setPlacemarks(ArrayList<Placemark> placemarks) {
    this.placemarks = placemarks;
}

public Placemark getCurrentPlacemark() {
    return currentPlacemark;
}

public void setCurrentPlacemark(Placemark currentPlacemark) {
    this.currentPlacemark = currentPlacemark;
}

public Placemark getRoutePlacemark() {
    return routePlacemark;
}

public void setRoutePlacemark(Placemark routePlacemark) {
    this.routePlacemark = routePlacemark;
}

}

And the SAX Handler to parse the kml:

package com.myapp.android.model.navigation;

import android.util.Log;
import com.myapp.android.myapp;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;

 } 

 /** Gets be called on closing tags like:

       if ("Route".equals(navigationDataSet.getCurrentPlacemark().getTitle())) 
               navigationDataSet.setRoutePlacemark(navigationDataSet.getCurrentPlacemark());

       }
 } 

 /** Gets be called on the following structure:

 @Override

        //navigationDataSet.getCurrentPlacemark().setCoordinates(new String(ch, start, length));
        buffer.append(ch, start, length);
    }
} 
}

and a simple placeMark bean:

package com.myapp.android.model.navigation;

public class Placemark {

String title;
String description;
String coordinates;
String address;

public String getTitle() {
    return title;
}
public void setTitle(String title) {

}
public String getDescription() {
    return description;
}
public void setDescription(String description) {
    this.description = description;
}
public String getCoordinates() {
    return coordinates;
}
public void setCoordinates(String coordinates) {
    this.coordinates = coordinates;
}
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}

}

On most POSIX systems, it is ignored. But, check your system to be sure.

The mode string can also include the letter 'b' either as last character or as a character between the characters in any of the two-character strings described above. This is strictly for compatibility with ISO/IEC 9899:1990 ('ISO C90') and has no effect; the 'b' is ignored.

The mode string can also include the letter 'b' either as a last character or as a character between the characters in any of the two- character strings described above. This is strictly for compatibility with C89 and has no effect; the 'b' is ignored on all POSIX conforming systems, including Linux. (Other systems may treat text files and binary files differently, and adding the 'b' may be a good idea if you do I/O to a binary file and expect that your program may be ported to non-UNIX environments.)

//Calling close and then quit will kill the driver running process.

The easiest way to do this is to run an iPad simulator using XCode and then add an entry in the hosts file (/etc/hosts) on the host system to point to your test site.

I know I'm late but my preferred way is:

:programend
pause>nul
GOTO programend

In this way the user cannot exit using enter.

Things that did not work for me:

• clicking the refresh icon (with or without shift)
• SHIFT-F5, CTRL-F5
• opening the page in an incognito window
• F12 (to open Dev tools) / (Dev tools) Settings / Disable cache (while dev tools is open)

What I mean by not working is: In the file system the .js file has been updated, but Chrome does not pick up the change. It means the page script executes with the old logic, Dev tools Scripts / ... / Compiled / ... shows the old .js content.

What does work for me:

• Close Chrome and re-open the page. After this Dev tools Scripts / ... / Compiled / ... shows updated .js content (matching the file system), and page scripts excute with updated logic.

Here is the Java 8+ example:

public static void pack(String sourceDirPath, String zipFilePath) throws IOException {
    Path p = Files.createFile(Paths.get(zipFilePath));
    try (ZipOutputStream zs = new ZipOutputStream(Files.newOutputStream(p))) {
        Path pp = Paths.get(sourceDirPath);
        Files.walk(pp)
          .filter(path -> !Files.isDirectory(path))
          .forEach(path -> {
              ZipEntry zipEntry = new ZipEntry(pp.relativize(path).toString());
              try {
                  zs.putNextEntry(zipEntry);
                  Files.copy(path, zs);
                  zs.closeEntry();
            } catch (IOException e) {
                System.err.println(e);
            }
          });
    }
}

I had a similar problem. The catalina.out logged this log Message

Apr 17, 2013 5:14:46 PM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart

Check the localhost.log in the tomcat log directory (in the same directory as catalina.out), to see the exception which caused this error.

This will eliminate the error and is type safe:

this.DNATranscriber[character as keyof typeof DNATranscriber]

Declare @MonthNumber int
SET @MonthNumber=DatePart(Month,GETDATE())
Select DateName( month , DateAdd( month , @MonthNumber , 0 ) - 1 )

Explaination:

1. First Decalre Variable MonthNumber
2. Get Current Month for DatePart which Return Month Number
3. Third Query Return Month Name

The best solution, where en is the English locale:

fraction.toLocaleString("en", {style: "percent"})

You need to pass an array of element to jsx. The problem is that forEach does not return anything (i.e it returns undefined). So it's better to use map because map returns an array:

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.map((answer, i) => {     
           console.log("Entered");                 
           // Return the element. Also pass key     
           return (<Answer key={answer} answer={answer} />) 
        })}
}

export default QuestionSet;

Generally speaking, fixed section should be set with width, height and top, bottom properties, otherwise it won't recognise its size and position.

If the used box is direct child for body and has neighbours, then it makes sense to check z-index and top, left properties, since they could overlap each other, which might affect your mouse hover while scrolling the content.

Here is the solution for a content box (a direct child of body tag) which is commonly used along with mobile navigation.

.fixed-content {
    position: fixed;
    top: 0;
    bottom:0;

    width: 100vw; /* viewport width */
    height: 100vh; /* viewport height */
    overflow-y: scroll;
    overflow-x: hidden;
}

Hope it helps anybody. Thank you!

The app is stored in %LocalAppData% in your %UserProfile%. So the full path could be:

C:\Users\username\AppData\Local\GitHub

This is one alternative for achieving the same but it avoids race condition caused by having two distinct "check ..and.. create" operations.

package main

import (
    "fmt"
    "os"
)

func main()  {
    if err := ensureDir("/test-dir"); err != nil {
        fmt.Println("Directory creation failed with error: " + err.Error())
        os.Exit(1)
    }
    // Proceed forward
}

func ensureDir(dirName string) error {

    err := os.MkdirAll(dirName, os.ModeDir)

    if err == nil || os.IsExist(err) {
        return nil
    } else {
        return err
    }
}

Get the json-framework and do this:

#import "SBJsonWriter.h"

...

SBJsonWriter *jsonWriter = [[SBJsonWriter alloc] init];

NSString *jsonString = [jsonWriter stringWithObject:myDictionary];  

[jsonWriter release];

myDictionary will be your dictionary.

in git version 1.7.9.5 this seems to work to export a single file from a remote

git archive --remote=ssh://host/pathto/repo.git HEAD README.md

This will cat the contents of the file README.md.

That selects the row number per country code, account, and currency. So, the rows with country code "US", account "XYZ" and currency "$USD" will each get a row number assigned from 1-n; the same goes for every other combination of those columns in the result set.

This query is kind of funny, because the order by clause does absolutely nothing. All the rows in each partition have the same country code, account, and currency, so there's no point ordering by those columns. The ultimate row numbers assigned in this particular query will therefore be unpredictable.

Hope that helps...

On POSIX platforms, you can use getcwd().

On Windows, you may use _getcwd(), as use of getcwd() has been deprecated.

For standard libraries, if Boost were standard enough for you, I would have suggested Boost::filesystem, but they seem to have removed path normalization from the proposal. You may have to wait until TR2 becomes readily available for a fully standard solution.

Best way would be first of all find all files in directory then use AWK NR (Number of Records Variable)

below is the command :

find <directory path>  -type f | awk  'END{print NR}'

example : - find /tmp/ -type f | awk 'END{print NR}'

If you are using windows os, you can download your desired opencv unofficial windows binary from here, and type something like pip install opencv_python-2.4.13.2-cp27-cp27m-win_amd64.whl in the directory of binary file.

Both Local System Account and Local Service would not work for me, i then set it to Network Service and this worked fine.

The WPF DataGrid has an IsReadOnly property that you can set to True to ensure that users cannot edit your DataGrid's cells.

You can also set this value for individual columns in your DataGrid as needed.

Yes, convert it to a string once the loop is done:

String str = data.ToString().TrimEnd(',');

Not sure if this is still extant but I'm guessing you need something like

((field Like "AA*") AND (field Not Like "BB*"))

Here is how to calculate the text height in Swift. You can then get the height from the rect and set the constraint height of the label or textView, etc.

let font = UIFont(name: "HelveticaNeue", size: 25)!
let text = "This is some really long text just to test how it works for calculating heights in swift of string sizes. What if I add a couple lines of text?"

let textString = text as NSString

let textAttributes = [NSFontAttributeName: font]

let textRect = textString.boundingRectWithSize(CGSizeMake(320, 2000), options: .UsesLineFragmentOrigin, attributes: textAttributes, context: nil)

Section 2 of RFC 2368 says that the body field is supposed to be in text/plain format, so you can't do HTML.

However even if you use plain text it's possible that some modern mail clients would render a URL as a clickable link anyway, though.

I had the same issue, running Netbeans 8.0 on Windows, and JRE 1.7.

I just installed JRE 1.8 from https://www.java.com/fr/download/ (note that it's called Version 8 but it's version 1.8 when you install it), and it fixed it.

TFS, like some other source control providers, such as Perforce, do this, as the system knows what the last version you successfully got was, so get latest turns into "get changes since x". If you play by its rules and actually check things out before editing them, you don't confuse matters, and "get latest" really does as it says.

As you've seen, you can force it to reassess everything, which has a much greater bandwidth usage, but behaves closer to how SourceSafe used to.

jQuery Validation Unobtrusive Native is a collection of ASP.Net MVC HTML helper extensions. These make use of jQuery Validation's native support for validation driven by HTML 5 data attributes. Microsoft shipped jquery.validate.unobtrusive.js back with MVC 3. It provided a way to apply data model validations to the client side using a combination of jQuery Validation and HTML 5 data attributes (that's the "unobtrusive" part).

Try creating another SQL view instead of a temporary table and then referencing it in the main SQL view. In other words, a view within a view. You can then drop the first view once you are done creating the main view.

That's right. You could try it in the interpreter like this:

>>> a_set = set(['a', 'b', 'c'])

>>> 'a' in a_set
True

>>>'d' in a_set
False

1. Upload setup.py to drive.
2. Mount the drive.
3. Get the path of setup.py.
4. !python PATH install.

Sounds like you should stay with the defaults ;-)

Seriously: The number of maximum parallel connections you should set depends on your expected tomcat usage and also on the number of cores on your server. More cores on your processor => more parallel threads that can be executed.

See here how to configure...

Only this snippet does not work for me:

background-image: url(image_path('transparent_2x2.png'));

But rename stylename.scss to stylename.css.scss helps me.

This has happened to me also, after undating to IOS11 on my iPhone. When I try to connect to the corporate network it bring up the corporate cert and says it isn't trusted. I press the 'trust' button and the connection fails and the cert does not appear in the trusted certs list.

yourbox {
   position: absolute;
   left: 100%;

left:100%; is the important issue here!

Run a packet sniffer (e.g., Wireshark) also on the peer to see whether it's the peer who's sending the RST or someone in the middle.

Here are some ways of doing this:

1. Importing font

For example, for using Roboto, install the package using

yarn add typeface-roboto

or

npm install typeface-roboto --save

In index.js:

import "typeface-roboto";

There are npm packages for a lot of open source fonts and most of Google fonts. You can see all fonts here. All the packages are from that project.

2. For fonts hosted by Third party

For example Google fonts, you can go to fonts.google.com where you can find links that you can put in your public/index.html

It'll be like

<link href="https://fonts.googleapis.com/css?family=Montserrat" rel="stylesheet">

or

<style>
    @import url('https://fonts.googleapis.com/css?family=Montserrat');
</style>

3. Downloading the font and adding it in your source code.

Download the font. For example, for google fonts, you can go to fonts.google.com. Click on the download button to download the font.

Move the font to fonts directory in your src directory

src
|
`----fonts
|      |
|      `-Lato/Lato-Black.ttf
|       -Lato/Lato-BlackItalic.ttf
|       -Lato/Lato-Bold.ttf
|       -Lato/Lato-BoldItalic.ttf
|       -Lato/Lato-Italic.ttf
|       -Lato/Lato-Light.ttf
|       -Lato/Lato-LightItalic.ttf
|       -Lato/Lato-Regular.ttf
|       -Lato/Lato-Thin.ttf
|       -Lato/Lato-ThinItalic.ttf
|
`----App.css

Now, in App.css, add this

@font-face {
  font-family: 'Lato';
  src: local('Lato'), url(./fonts/Lato-Regular.otf) format('opentype');
}

@font-face {
    font-family: 'Lato';
    font-weight: 900;
    src: local('Lato'), url(./fonts/Lato-Bold.otf) format('opentype');
}

@font-face {
    font-family: 'Lato';
    font-weight: 900;
    src: local('Lato'), url(./fonts/Lato-Black.otf) format('opentype');
}

For ttf format, you have to mention format('truetype'). For woff, format('woff')

Now you can use the font in classes.

.modal-title {
    font-family: Lato, Arial, serif;
    font-weight: black;
}

4. Using web-font-loader package

Install package using

yarn add webfontloader

or

npm install webfontloader --save

In src/index.js, you can import this and specify the fonts needed

import WebFont from 'webfontloader';

WebFont.load({
   google: {
     families: ['Titillium Web:300,400,700', 'sans-serif']
   }
});

You want to use a JFileChooser object. It will open and be modal, and block in the thread that opened it until you choose a file.

Open:

JFileChooser fileChooser = new JFileChooser();
if (fileChooser.showOpenDialog(modalToComponent) == JFileChooser.APPROVE_OPTION) {
  File file = fileChooser.getSelectedFile();
  // load from file
}

Save:

JFileChooser fileChooser = new JFileChooser();
if (fileChooser.showSaveDialog(modalToComponent) == JFileChooser.APPROVE_OPTION) {
  File file = fileChooser.getSelectedFile();
  // save to file
}

There are more options you can set to set the file name extension filter, or the current directory. See the API for the javax.swing.JFileChooser for details. There is also a page for "How to Use File Choosers" on Oracle's site:

http://download.oracle.com/javase/tutorial/uiswing/components/filechooser.html

Swift 3:

String(data: data, encoding: .utf8)

You can also use OrderedDict:

In [183]: from collections import OrderedDict

In [184]: data = OrderedDict()

In [185]: data['one thing'] = [1,2,3,4]

In [186]: data['second thing'] = [0.1,0.2,1,2]

In [187]: data['other thing'] = ['a','e','i','o']

In [188]: frame = pd.DataFrame(data)

In [189]: frame
Out[189]:
   one thing  second thing other thing
0          1           0.1           a
1          2           0.2           e
2          3           1.0           i
3          4           2.0           o

Write below code into your MainActivity file after setContentView(R.layout.activity_main);

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

And below import statement into your java file.

import android.os.StrictMode;

Using the index:

df[1:4,]

Where the values in the parentheses can be interpreted as either logical, numeric, or character (matching the respective names):

df[row.index, column.index]

Read help(`[`) for more detail on this subject, and also read about index matrices in the Introduction to R.

Null is supported by the Stream provided My library AbacusUtil. Here is code:

Stream.of(things).map(e -> resolve(e).orNull()).skipNull().first();

A one-liner using ES6 arrow function and ternary operator:

Object.keys(obj).forEach(key => obj[key] === undefined ? delete obj[key] : {});

Or use short-circuit evaluation instead of ternary: (@Matt Langlois, thanks for the info!)

Object.keys(obj).forEach(key => obj[key] === undefined && delete obj[key])

Same example using if statement:

Object.keys(obj).forEach(key => {
  if (obj[key] === undefined) {
    delete obj[key];
  }
});

If you want to remove the items from nested objects as well, you can use a recursive function:

const removeEmpty = (obj) => {
  let newObj = {};
  Object.keys(obj).forEach((key) => {
    if (obj[key] === Object(obj[key])) newObj[key] = removeEmpty(obj[key]);
    else if (obj[key] !== undefined) newObj[key] = obj[key];
  });
  return newObj;
};

You have to give the path to jdk ...typically C:\Program Files\Java.. Still if it is asking you for the path then Check this http://www.shellperson.net/oracle-sql-developer-enter-the-full-pathname-for-java-exe/

I found the SVG marker/icon to be best one yet. It is very flexible and allows any color you like. You can customize the entire icon without much of a hassle:

function createIcon(markerColor) {
  /* ...Code ommitted ... */

  return new L.DivIcon.SVGIcon({
            color: markerColor,
            iconSize: [15,30],
            circleRatio: 0.35
  });
}

A quick and dirty solution I have used is to place the EditText inside of a FrameLayout. The margins of the EditText control the thickness of the border and the border color is determined by the background color of the FrameLayout.

Example:

<FrameLayout
    android:id="@+id/frameLayout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#000000">

    <EditText
        android:id="@+id/editText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="3dp"
        android:background="@android:color/white"
        android:ems="10"
        android:inputType="text"
        android:textSize="24sp" />
</FrameLayout>

But I would recommend, and the vast majority of the time I do, drawables for borders. Elite's answer is what I would go for in that case.

Using Fluent DateTime:

var monday = DateTime.Now.Previous(DayOfWeek.Monday);
var sunday = DateTime.Now.Previous(DayOfWeek.Sunday);

You do not need to give an index.

Instead of doing order[0].push(a[i]), just do order.push(a[i]).

I believe you would have to "git revert" back to that commit and then push it. Or you could cherry-pick a commit into a new branch, and push that to the branch on the remote repository. Something like:

git branch onecommit
git checkout onecommit
git cherry-pick 7300a6130d9447e18a931e898b64eefedea19544 # From the other branch
git push origin {branch}

Checkout the .SaveAs() method in Excel object.

wbWorkbook.SaveAs("c:\yourdesiredFilename.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSV)

Or following:

public static void SaveAs()
{
    Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.ApplicationClass();
    Microsoft.Office.Interop.Excel.Workbook wbWorkbook = app.Workbooks.Add(Type.Missing);
    Microsoft.Office.Interop.Excel.Sheets wsSheet = wbWorkbook.Worksheets;
    Microsoft.Office.Interop.Excel.Worksheet CurSheet = (Microsoft.Office.Interop.Excel.Worksheet)wsSheet[1];

    Microsoft.Office.Interop.Excel.Range thisCell = (Microsoft.Office.Interop.Excel.Range)CurSheet.Cells[1, 1];

    thisCell.Value2 = "This is a test.";

    wbWorkbook.SaveAs(@"c:\one.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
    wbWorkbook.SaveAs(@"c:\two.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSVWindows, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

    wbWorkbook.Close(false, "", true);
}

Store Unique characters in list

Method 1:

uniue_char = list(set('aaabcabccd'))
#['a', 'b', 'c', 'd']

Method 2: By Loop ( Complex )

uniue_char = []
for c in 'aaabcabccd':
    if not c in uniue_char:
        uniue_char.append(c)
print(uniue_char)
#['a', 'b', 'c', 'd']

I recently had the problem of deleting the tnsnames.ora from the path where I had it, my solution was to create an environment variable called TNS_NAME with the value the path where the tnsnames.ora file is located and ready

What about just using virtual desktops? You can spread your windows around among multiple workspaces. Something like Virtual Dimension should give you most of that functionality. I use virtual desktops all the time on Linux, and it's the next best thing to multiple monitors.

Remember that the US date format is different from the UK. Using the UK format, it needs to be, e.g.

--                                  dd/mm/ccyy hh:mm:ss     
dbo.no_time(at.date_stamp) between '22/05/2016 00:00:01' and '22/07/2016 23:59:59' 

When define some member variable outside any member method, the variable can be either static or non-static depending on how the variable is expressed.

• CLASSNAME.var is static variable
• INSTANCENAME.var is not static variable.
• self.var inside class is not static variable.
• var inside the class member function is not defined.

For example:

#!/usr/bin/python

class A:
    var=1

    def printvar(self):
        print "self.var is %d" % self.var
        print "A.var is %d" % A.var


    a = A()
    a.var = 2
    a.printvar()

    A.var = 3
    a.printvar()

The results are

self.var is 2
A.var is 1
self.var is 2
A.var is 3

You can use URL encoding to encode the newline as %0A.

mailto:[email protected]?subject=test&body=type%20your%0Amessage%20here

While the above appears to work in many cases, user olibre points out that the RFC governing the mailto URI scheme specifies that %0D%0A (carriage return + line feed) should be used instead of %0A (line feed). See also: Newline Representations.

select datename(DAY,GETDATE()) +'-'+ datename(MONTH,GETDATE()) +'- '+ 
       datename(YEAR,GETDATE()) as 'yourcolumnname'

I always like to use Ansi escape characters:

echo -e "Enter your password: \x1B[8m"
echo -e "\x1B[0m"

8m makes text invisible and 0m resets text to "normal." The -e makes Ansi escapes possible.

The only caveat is that you can still copy and paste the text that is there, so you probably shouldn't use this if you really want security.

It just lets people not look at your passwords when you type them in. Just don't leave your computer on afterwards. :)

NOTE:

The above is platform independent as long as it supports Ansi escape sequences.

However, for another Unix solution, you could simply tell read to not echo the characters...

printf "password: "
let pass $(read -s)
printf "\nhey everyone, the password the user just entered is $pass\n"

Just to confirm though you probably did...

Did you include the

<!--  tell spring to use annotation based congfigurations -->
<context:annotation-config />
<!--  tell spring where to find the beans -->
<context:component-scan base-package="zz.yy.abcd" />

bits in your application context.xml?

Also I'm not so sure you'd be able to use a jta transaction type with this kind of setup? Wouldn't that require a data source managed connection pool? So try RESOURCE_LOCAL instead.

Another way of doing this if you want to redirect to any url source after the specified point of time

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.*;

public class MyServlet extends HttpServlet


{

public void doGet(HttpServletRequest request,HttpServletResponse response) throws IOException

{

response.setContentType("text/html");

PrintWriter pw=response.getWriter();

pw.println("<b><centre>Redirecting to Google<br>");


response.setHeader("refresh,"5;https://www.google.com/"); // redirects to url  after 5 seconds


pw.close();
}

}

The main difference between the web containers and application server is that most web containers such as Apache Tomcat implements only basic JSR like Servlet, JSP, JSTL wheres Application servers implements the entire Java EE Specification. Every application server contains web container.

You can also use COALESCE ( expression [ ,...n ] ) - returns first non-null like:

SELECT COALESCE(MAX(X),0) AS MaxX
FROM tbl
WHERE XID = 1

You can also try using apply with get method of dictionary, seems to be little faster than replace:

data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Testing with timeit:

%%timeit
data['sex'].replace([0,1],['Female','Male'],inplace=True)

Result:

The slowest run took 5.83 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 510 µs per loop

Using apply:

%%timeit
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Result:

The slowest run took 5.92 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 331 µs per loop

Note: apply with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.

I take it that is a Vista Window! I often got this when first trying to port a DirectX program from XPsp3 to Vista.

It's a .dll problem. The OpenCV runtime.dll will call upon a system.dll that will be no longer shipped Vista, so unfortunately you will have to to a bit of hunting to find which system.dll it's trying to find. (system.dll could be vc2010 or vista)

This error is also caused by incorrect installation of .dlls (i.e not rolling out) hth Happy hunting

The differences are covered at the PostgreSQL documentation for date/time types. Yes, the treatment of TIME or TIMESTAMP differs between one WITH TIME ZONE or WITHOUT TIME ZONE. It doesn't affect how the values are stored; it affects how they are interpreted.

The effects of time zones on these data types is covered specifically in the docs. The difference arises from what the system can reasonably know about the value:

• With a time zone as part of the value, the value can be rendered as a local time in the client.

• Without a time zone as part of the value, the obvious default time zone is UTC, so it is rendered for that time zone.

The behaviour differs depending on at least three factors:

• The timezone setting in the client.
• The data type (i.e. WITH TIME ZONE or WITHOUT TIME ZONE) of the value.
• Whether the value is specified with a particular time zone.

Here are examples covering the combinations of those factors:

foo=> SET TIMEZONE TO 'Japan';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
      timestamp      
---------------------
 2011-01-01 00:00:00
(1 row)

foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP WITH TIME ZONE;

Using a text editor, check for ^M (control-M, or carriage return) at the end of each line. You will need to remove them first, then append the additional text at the end of the line.

sed -i 's|^M||g' ips.txt
sed -i 's|$|:80|g' ips.txt

From @Jon Skeet comment, really the String value is "null". Following code solved it

if (userEmail != null && !userEmail.isEmpty() && !userEmail.equals("null")) 

Only checked and checked="checked" are valid. Your other options depend on error recovery in browsers.

checked="yes" and checked="true" are particularly bad as they imply that checked="no" and checked="false" will set the default state to be unchecked … which they will not.

As for infinite loops for(;;) loop is better than while(1) since while evaluates every time the condition but again it depends on the compiler.

these functions will solve the problem, you need to implement the DrawThumbnails function and have a global variable to store the images. I love to get this to work with a class object that has the ThumbnailImageArray as a member variable, but am struggling!

called as in addThumbnailImages(10);

var ThumbnailImageArray = [];

function addThumbnailImages(MaxNumberOfImages)
{
    var imgs = [];

    for (var i=1; i<MaxNumberOfImages; i++)
    {
        imgs.push(i+".jpeg");
    }

    preloadimages(imgs).done(function (images){
            var c=0;

            for(var i=0; i<images.length; i++)
            {
                if(images[i].width >0) 
                {
                    if(c != i)
                        images[c] = images[i];
                    c++;
                }
            }

            images.length = c;

            DrawThumbnails();
        });
}



function preloadimages(arr)
{
    var loadedimages=0
    var postaction=function(){}
    var arr=(typeof arr!="object")? [arr] : arr

    function imageloadpost()
    {
        loadedimages++;
        if (loadedimages==arr.length)
        {
            postaction(ThumbnailImageArray); //call postaction and pass in newimages array as parameter
        }
    };

    for (var i=0; i<arr.length; i++)
    {
        ThumbnailImageArray[i]=new Image();
        ThumbnailImageArray[i].src=arr[i];
        ThumbnailImageArray[i].onload=function(){ imageloadpost();};
        ThumbnailImageArray[i].onerror=function(){ imageloadpost();};
    }
    //return blank object with done() method    
    //remember user defined callback functions to be called when images load
    return  { done:function(f){ postaction=f || postaction } };
}

I had the same problem and solved it by using the default woocommerce hook to display the product image.

while ( $loop->have_posts() ) : $loop->the_post();
   echo woocommerce_get_product_thumbnail('woocommerce_full_size');
endwhile;

Available parameters:

• woocommerce_thumbnail
• woocommerce_full_size

If you don't have privileges to create a view in Oracle, a "hack" around it to use MS Access :-(

In MS Access, create a pass through query with your sql (but add where clause to just select 1 record), create a select query from the view (very important), selecting all *, then create a make table from the select query. When this runs it will create a table with one record, all the data types should "match" oracle. i.e. Passthrough --> Select --> MakeTable --> Table

I am sure there are other better ways, but if you have limited tools and privileges this will work.

There's a class/jar available on SourceForge.net that uses Java instrumentation to calculate the size of any object. Here's a link to the description: java.sizeOf

I have used this simple and clever way for creating random color in Java,

Random random = new Random();
        System.out.println(String.format("#%06x", random.nextInt(256*256*256)));

Where #%06x gives you zero-padded hex (always 6 characters long).

Looks like YouTube has updated their JS API so this is available by default! You can use an existing YouTube iframe's ID...

<iframe id="player" src="http://www.youtube.com/embed/M7lc1UVf-VE?enablejsapi=1&origin=http://example.com" frameborder="0"></iframe>

...in your JS...

var player;
function onYouTubeIframeAPIReady() {
  player = new YT.Player('player', {
    events: {
      'onStateChange': onPlayerStateChange
    }
  });
}

function onPlayerStateChange() {
  //...
}

...and the constructor will use your existing iframe instead of replacing it with a new one. This also means you don't have to specify the videoId to the constructor.

See Loading a video player

You cannot concatenate a string with an int. You would need to convert your int to a string using the str function, or use formatting to format your output.

Change: -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

to: -

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

or: -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")

val = -3.1234

fraction = abs(val - as.integer(val) ) 

In my case I ran the following command and it worked (not that I was expecting it to):

sudo pip uninstall pip

You're missing comma (,) inbetween:

>>> ((1,2) (2,3))
Traceback (most recent call last):

Put comma:

((1, 2), (2, 3))

If you were programming in C, then assuming name really is a fixed-length array like you say, you have to do something like the following:

char filename[sizeof(name) + 4];
strcpy (filename, name) ;
strcat (filename, ".txt") ;
FILE* fp = fopen (filename,...

You see now why everybody recommends std::string?

An example of use :

You consume many classes that have a commun property 'CreationDate' :

public class Contact
{
    // some properties

    public DateTime CreationDate { get; set; }        
}

public class Company
{
    // some properties

    public DateTime CreationDate { get; set; }

}

public class Opportunity
{
    // some properties

    public DateTime CreationDate { get; set; }

}

If you write a commun method that retrieves the value of the 'CreationDate' Property, you'd have to use reflection:

    static DateTime RetrieveValueOfCreationDate(Object item)
    {
        return (DateTime)item.GetType().GetProperty("CreationDate").GetValue(item);
    }

With the 'dynamic' concept, your code is much more elegant :

    static DateTime RetrieveValueOfCreationDate(dynamic item)
    {
        return item.CreationDate;
    }

In the form closest to your original:

import datetime

def UtcNow():
    now = datetime.datetime.utcnow()
    return now

If you need to know the number of seconds from 1970-01-01 rather than a native Python datetime, use this instead:

return (now - datetime.datetime(1970, 1, 1)).total_seconds()

Python has naming conventions that are at odds with what you might be used to in Javascript, see PEP 8. Also, a function that simply returns the result of another function is rather silly; if it's just a matter of making it more accessible, you can create another name for a function by simply assigning it. The first example above could be replaced with:

utc_now = datetime.datetime.utcnow

The fixform trick is neat, but:

1. You may not have access to the code of what loads in the new window.

2. Even if you do, you are depending on the fact that it always loads, error free.

3. And you are depending on the fact that the user won't click another button before the other page gets a chance to load and run fixform.

I would suggest doing this instead:

OnClientClick="aspnetForm.target ='_blank';setTimeout('fixform()', 500);"

And set up fixform on the same page, looking like this:

function fixform() {
   document.getElementById("aspnetForm").target = '';
}

To be honest I have to add my 2 cents.

You can do it with msbuild.exe. There are many version of the msbuild.exe.

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\msbuild.exe C:\Windows\Microsoft.NET\Framework64\v3.5\msbuild.exe C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe
C:\Windows\Microsoft.NET\Framework\v2.0.50727\msbuild.exe C:\Windows\Microsoft.NET\Framework\v3.5\msbuild.exe C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe

Use version you need. Basically you have to use the last one.

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe

So how to do it.

1. Run the COMMAND window

2. Input the path to msbuild.exe

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe

1. Input the path to the project solution like

"C:\Users\Clark.Kent\Documents\visual studio 2012\Projects\WpfApplication1\WpfApplication1.sln"

1. Add any flags you need after the solution path.

2. Press ENTER

Note you can get help about all possible flags like

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe /help

For Power-Shell

./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'

For linux(burrowing asnwer from @0x8BADF00D)

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

For single string find in power shell

./adb shell getprop | Select-String -Pattern 'model'

or

./adb shell getprop | Select-String -Pattern '(model)'

For multiple

./adb shell getprop | Select-String -Pattern '(a|b|c|d)'

I faced to the same problem. I solved it by

1. navigate to HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath and edit the default key with the output of C:\> where python.exe command.
2. navigate to HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath\InstallGroup and edit the default key with Python 3.4

Note: My python version is 3.4 and you need to replace 3.4 with your python version.

Normally you can find Registry entries for Python in HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\<version>. You just need to copy those entries to HKEY_CURRENT_USER\Software\Python\PythonCore\<version>

Yes, this is a 'new style' object. It was a feature introduced in python2.2.

New style objects have a different object model to classic objects, and some things won't work properly with old style objects, for instance, super(), @property and descriptors. See this article for a good description of what a new style class is.

SO link for a description of the differences: What is the difference between old style and new style classes in Python?

  public static void copyFile(File oldLocation, File newLocation) throws IOException {
        if ( oldLocation.exists( )) {
            BufferedInputStream  reader = new BufferedInputStream( new FileInputStream(oldLocation) );
            BufferedOutputStream  writer = new BufferedOutputStream( new FileOutputStream(newLocation, false));
            try {
                byte[]  buff = new byte[8192];
                int numChars;
                while ( (numChars = reader.read(  buff, 0, buff.length ) ) != -1) {
                    writer.write( buff, 0, numChars );
                }
            } catch( IOException ex ) {
                throw new IOException("IOException when transferring " + oldLocation.getPath() + " to " + newLocation.getPath());
            } finally {
                try {
                    if ( reader != null ){                      
                        writer.close();
                        reader.close();
                    }
                } catch( IOException ex ){
                    Log.e(TAG, "Error closing files when transferring " + oldLocation.getPath() + " to " + newLocation.getPath() ); 
                }
            }
        } else {
            throw new IOException("Old location does not exist when transferring " + oldLocation.getPath() + " to " + newLocation.getPath() );
        }
    }  

You used the singular in your question but there are typically several authoritative name servers, the RFC 1034 recommends at least two.

Unless you mean "primary name server" and not "authoritative name server". The secondary name servers are authoritative.

To find out the name servers of a domain on Unix:

  % dig +short NS stackoverflow.com
 ns52.domaincontrol.com.
 ns51.domaincontrol.com.

To find out the server listed as primary (the notion of "primary" is quite fuzzy these days and typically has no good answer):

% dig +short  SOA stackoverflow.com | cut -d' ' -f1
ns51.domaincontrol.com.

To check discrepencies between name servers, my preference goes to the old check_soa tool, described in Liu & Albitz "DNS & BIND" book (O'Reilly editor). The source code is available in http://examples.oreilly.com/dns5/

% check_soa stackoverflow.com
ns51.domaincontrol.com has serial number 2008041300
ns52.domaincontrol.com has serial number 2008041300

Here, the two authoritative name servers have the same serial number. Good.

Use database field type BLOB to store arrays.

Ref: http://us.php.net/manual/en/function.serialize.php

Return Values

Returns a string containing a byte-stream representation of value that can be stored anywhere.

Note that this is a binary string which may include null bytes, and needs to be stored and handled as such. For example, serialize() output should generally be stored in a BLOB field in a database, rather than a CHAR or TEXT field.

I had this issue, and after doing some debugging, and searching I realized that the SERVER (Godaddy) can have issues.

I recommend you contact your Web hosting Provider and talk to them about Quota Restrictions on the mail function (They do this to prevent people doing spam bots or mass emailing (spam) ).

They may be able to advise you of their limits, and if you're exceeding them. You can also possibly upgrade limit by going to private server.

After talking with GoDaddy for 15 minutes the tech support was able to resolve this within 20 minutes.

This helped me out a lot, and I wanted to share it so if someone else comes across this they can try this method if all fails, or before they try anything else.

Here's a bit more detail to expand on Hooked's answer. When I first read that answer, I missed the instruction to call clf() instead of creating a new figure. clf() on its own doesn't help if you then go and create another figure.

Here's a trivial example that causes the warning:

from matplotlib import pyplot as plt, patches
import os


def main():
    path = 'figures'
    for i in range(21):
        _fig, ax = plt.subplots()
        x = range(3*i)
        y = [n*n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.clf()
    print('Done.')

main()

To avoid the warning, I have to pull the call to subplots() outside the loop. In order to keep seeing the rectangles, I need to switch clf() to cla(). That clears the axis without removing the axis itself.

from matplotlib import pyplot as plt, patches
import os


def main():
    path = 'figures'
    _fig, ax = plt.subplots()
    for i in range(21):
        x = range(3*i)
        y = [n*n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.cla()
    print('Done.')

main()

If you're generating plots in batches, you might have to use both cla() and close(). I ran into a problem where a batch could have more than 20 plots without complaining, but it would complain after 20 batches. I fixed that by using cla() after each plot, and close() after each batch.

from matplotlib import pyplot as plt, patches
import os


def main():
    for i in range(21):
        print('Batch {}'.format(i))
        make_plots('figures')
    print('Done.')


def make_plots(path):
    fig, ax = plt.subplots()
    for i in range(21):
        x = range(3 * i)
        y = [n * n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.cla()
    plt.close(fig)


main()

I measured the performance to see if it was worth reusing the figure within a batch, and this little sample program slowed from 41s to 49s (20% slower) when I just called close() after every plot.

The issue is not actually with the import statement, it's with anything being before the for loop. Or more specifically, anything appearing before an inlined block.

For example, these all work:

python -c "import sys; print 'rob'"
python -c "import sys; sys.stdout.write('rob\n')"

If import being a statement were an issue, this would work, but it doesn't:

python -c "__import__('sys'); for r in range(10): print 'rob'"

For your very basic example, you could rewrite it as this:

python -c "import sys; map(lambda x: sys.stdout.write('rob%d\n' % x), range(10))"

However, lambdas can only execute expressions, not statements or multiple statements, so you may still be unable to do the thing you want to do. However, between generator expressions, list comprehension, lambdas, sys.stdout.write, the "map" builtin, and some creative string interpolation, you can do some powerful one-liners.

The question is, how far do you want to go, and at what point is it not better to write a small .py file which your makefile executes instead?

For fitting y = A + B log x, just fit y against (log x).

>>> x = numpy.array([1, 7, 20, 50, 79])
>>> y = numpy.array([10, 19, 30, 35, 51])
>>> numpy.polyfit(numpy.log(x), y, 1)
array([ 8.46295607,  6.61867463])
# y ˜ 8.46 log(x) + 6.62

For fitting y = Ae^Bx, take the logarithm of both side gives log y = log A + Bx. So fit (log y) against x.

Note that fitting (log y) as if it is linear will emphasize small values of y, causing large deviation for large y. This is because polyfit (linear regression) works by minimizing ?_i (?Y)² = ?_i (Y_i − Y_i)². When Y_i = log y_i, the residues ?Y_i = ?(log y_i) ˜ ?y_i / |y_i|. So even if polyfit makes a very bad decision for large y, the "divide-by-|y|" factor will compensate for it, causing polyfit favors small values.

This could be alleviated by giving each entry a "weight" proportional to y. polyfit supports weighted-least-squares via the w keyword argument.

>>> x = numpy.array([10, 19, 30, 35, 51])
>>> y = numpy.array([1, 7, 20, 50, 79])
>>> numpy.polyfit(x, numpy.log(y), 1)
array([ 0.10502711, -0.40116352])
#    y ˜ exp(-0.401) * exp(0.105 * x) = 0.670 * exp(0.105 * x)
# (^ biased towards small values)
>>> numpy.polyfit(x, numpy.log(y), 1, w=numpy.sqrt(y))
array([ 0.06009446,  1.41648096])
#    y ˜ exp(1.42) * exp(0.0601 * x) = 4.12 * exp(0.0601 * x)
# (^ not so biased)

Note that Excel, LibreOffice and most scientific calculators typically use the unweighted (biased) formula for the exponential regression / trend lines. If you want your results to be compatible with these platforms, do not include the weights even if it provides better results.

Now, if you can use scipy, you could use scipy.optimize.curve_fit to fit any model without transformations.

For y = A + B log x the result is the same as the transformation method:

>>> x = numpy.array([1, 7, 20, 50, 79])
>>> y = numpy.array([10, 19, 30, 35, 51])
>>> scipy.optimize.curve_fit(lambda t,a,b: a+b*numpy.log(t),  x,  y)
(array([ 6.61867467,  8.46295606]), 
 array([[ 28.15948002,  -7.89609542],
        [ -7.89609542,   2.9857172 ]]))
# y ˜ 6.62 + 8.46 log(x)

For y = Ae^Bx, however, we can get a better fit since it computes ?(log y) directly. But we need to provide an initialize guess so curve_fit can reach the desired local minimum.

>>> x = numpy.array([10, 19, 30, 35, 51])
>>> y = numpy.array([1, 7, 20, 50, 79])
>>> scipy.optimize.curve_fit(lambda t,a,b: a*numpy.exp(b*t),  x,  y)
(array([  5.60728326e-21,   9.99993501e-01]),
 array([[  4.14809412e-27,  -1.45078961e-08],
        [ -1.45078961e-08,   5.07411462e+10]]))
# oops, definitely wrong.
>>> scipy.optimize.curve_fit(lambda t,a,b: a*numpy.exp(b*t),  x,  y,  p0=(4, 0.1))
(array([ 4.88003249,  0.05531256]),
 array([[  1.01261314e+01,  -4.31940132e-02],
        [ -4.31940132e-02,   1.91188656e-04]]))
# y ˜ 4.88 exp(0.0553 x). much better.

Simple one

To remove it:

.form-control, .btn {
    box-shadow: none !important;
    outline: none !important;
}

To change it

.form-control, .btn {
    box-shadow: new-value !important;
    outline: new-value !important;
}

It seems easy for me that use plt.savefig() function after plot() function:

import matplotlib.pyplot as plt
dtf = pd.DataFrame.from_records(d,columns=h)
dtf.plot()
plt.savefig('~/Documents/output.png')

Update: Using DateTimeFormat, introduced in java 8:

The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.

Your input format looks quite standard, except the trailing Z. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'". The trailing 'Z' is the interesting part. Usually there's time zone data here, like -0700. So the pattern would be ...Z, i.e. without apostrophes.

The output format is way more simple: "dd-MM-yyyy". Mind the small y -s.

Here is the example code:

DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018

Original answer - with old API SimpleDateFormat

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018

 return $this->db->select('(CASE 
            enter code hereWHEN orderdetails.ProductID = 0   THEN dealmaster.deal_name
            WHEN orderdetails.DealID = 0 THEN products.name
            END) as product_name')

The non-greedy regex modifiers are like their greedy counter-parts but with a ? immediately following them:

*  - zero or more
*? - zero or more (non-greedy)
+  - one or more
+? - one or more (non-greedy)
?  - zero or one
?? - zero or one (non-greedy)

I noticed there was not an actual full code answer, so as i come across this, i have created a function, that does change the font, which can be easily modified. I have tested this in

- XP SP3 and Win 10 Pro 64

private void SetFont(Form f, string name, int size, FontStyle style)
{
    Font replacementFont = new Font(name, size, style);
    f.Font = replacementFont;
}

Hint: replace Form to either Label, RichTextBox, TextBox, or any other relative control that uses fonts to change the font on them. By using the above function thus making it completely dynamic.

    /// To call the function do this.
    /// e.g in the form load event etc.

public Form1()
{
      InitializeComponent();
      SetFont(this, "Arial", 8, FontStyle.Bold);  
      // This sets the whole form and 
      // everything below it.
      // Shaun Cassidy.
}

You can also, if you want a full libary so you dont have to code all the back end bits, you can download my dll from Github.

Github DLL

/// and then import the namespace
using Droitech.TextFont;

/// Then call it using:
TextFontClass fClass = new TextFontClass();
fClass.SetFont(this, "Arial", 8, FontStyle.Bold);

Simple.

According to Flexbugs:

In IE 10-11, min-height declarations on flex containers work to size the containers themselves, but their flex item children do not seem to know the size of their parents. They act as if no height has been set at all.

Here are a couple of workarounds:

1. Always fill the viewport + scrollable <aside> and <section>:

html {
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
  height: 100%;
  margin: 0;
}

header,
footer {
  background: #7092bf;
}

main {
  flex: 1;
  display: flex;
}

aside, section {
  overflow: auto;
}

aside {
  flex: 0 0 150px;
  background: #3e48cc;
}

section {
  flex: 1;
  background: #9ad9ea;
}

<header>
  <p>header</p>
</header>

<main>
  <aside>
    <p>aside</p>
  </aside>
  <section>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
  </section>
</main>

<footer>
  <p>footer</p>
</footer>

2. Fill the viewport initially + normal page scroll with more content:

html {
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
  height: 100%;
  margin: 0;
}

header,
footer {
  background: #7092bf;
}

main {
  flex: 1 0 auto;
  display: flex;
}

aside {
  flex: 0 0 150px;
  background: #3e48cc;
}

section {
  flex: 1;
  background: #9ad9ea;
}

<header>
  <p>header</p>
</header>

<main>
  <aside>
    <p>aside</p>
  </aside>
  <section>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
  </section>
</main>

<footer>
  <p>footer</p>
</footer>
