Emulation may seem daunting but is actually quite easier than simulating.

Any processor typically has a well-written specification that describes states, interactions, etc.

If you did not care about performance at all, then you could easily emulate most older processors using very elegant object oriented programs. For example, an X86 processor would need something to maintain the state of registers (easy), something to maintain the state of memory (easy), and something that would take each incoming command and apply it to the current state of the machine. If you really wanted accuracy, you would also emulate memory translations, caching, etc., but that is doable.

In fact, many microchip and CPU manufacturers test programs against an emulator of the chip and then against the chip itself, which helps them find out if there are issues in the specifications of the chip, or in the actual implementation of the chip in hardware. For example, it is possible to write a chip specification that would result in deadlocks, and when a deadline occurs in the hardware it's important to see if it could be reproduced in the specification since that indicates a greater problem than something in the chip implementation.

Of course, emulators for video games usually care about performance so they don't use naive implementations, and they also include code that interfaces with the host system's OS, for example to use drawing and sound.

Considering the very slow performance of old video games (NES/SNES, etc.), emulation is quite easy on modern systems. In fact, it's even more amazing that you could just download a set of every SNES game ever or any Atari 2600 game ever, considering that when these systems were popular having free access to every cartridge would have been a dream come true.

It is also (Transact-SQL) ... according to BOL.

I think you probably want to use a token list for this purpose: to set up the token list \newtoks\packagename to assign the name: \packagename={New Name for the package} to put the name into your output: \the\packagename.

you have forgotten width of parent

.parent {_x000D_
   display: flex;_x000D_
   justify-content: center;_x000D_
   position: absolute;_x000D_
   width:100%_x000D_
 }

<div class="parent">_x000D_
  <div class="child">text</div>_x000D_
</div>

For me the answer of @Dane White is OK, first I did not like using Runnable but I could not find any alternatives.

Here another implementation I preferred more:

public class OptionalConsumer<T> {
    private Optional<T> optional;

    private OptionalConsumer(Optional<T> optional) {
        this.optional = optional;
    }

    public static <T> OptionalConsumer<T> of(Optional<T> optional) {
        return new OptionalConsumer<>(optional);
    }

    public OptionalConsumer<T> ifPresent(Consumer<T> c) {
        optional.ifPresent(c);
        return this;
    }

    public OptionalConsumer<T> ifNotPresent(Runnable r) {
        if (!optional.isPresent()) {
            r.run();
        }
        return this;
    }
}

Then:

Optional<Any> o = Optional.of(...);
OptionalConsumer.of(o).ifPresent(s -> System.out.println("isPresent " + s))
                .ifNotPresent(() -> System.out.println("! isPresent"));

Update 1:

the above solution for the traditional way of development when you have the value and want to process it but what if I want to define the functionality and the execution will be then, check below enhancement;

public class OptionalConsumer<T> implements Consumer<Optional<T>> {
private final Consumer<T> c;
private final Runnable r;

public OptionalConsumer(Consumer<T> c, Runnable r) {
    super();
    this.c = c;
    this.r = r;
}

public static <T> OptionalConsumer<T> of(Consumer<T> c, Runnable r) {
    return new OptionalConsumer(c, r);
}

@Override
public void accept(Optional<T> t) {
    if (t.isPresent()) {
        c.accept(t.get());
    }
    else {
        r.run();
    }
}

Then could be used as:

Consumer<Optional<Integer>> c = OptionalConsumer.of(
    System.out::println, 
    () -> System.out.println("Not fit")
);

IntStream.range(0, 100)
    .boxed()
    .map(i -> Optional.of(i)
    .filter(j -> j % 2 == 0))
    .forEach(c);

In this new code you have 3 things:

1. can define the functionality before the existing of an object easy.
2. not creating object reference for each Optional, only one, you have so less memory than less GC.
3. it is implementing consumer for better usage with other components.

By the way, now its name is more descriptive it is actually Consumer<Optional<?>>

It is worth mentioning that 2>&1 means that standard error will be redirected too, together with standard output. So

someCommand | tee someFile

gives you just the standard output in the file, but not the standard error: standard error will appear in console only. To get standard error in the file too, you can use

someCommand 2>&1 | tee someFile

(source: In the shell, what is " 2>&1 "? ). Finally, both the above commands will truncate the file and start clear. If you use a sequence of commands, you may want to get output&error of all of them, one after another. In this case you can use -a flag to "tee" command:

someCommand 2>&1 | tee -a someFile

Using System Preferences:

Step 1: Click the Apple icon (at the top left of the screen) and select System Preferences.

Step 2: Click Network.

Step 3: Select your network connection and then click Advanced.

Step 4: Select the TCP/IP tab and find your gateway IP address listed next to Router.

In android studio you can easily press:

1. Ctrl + Shift + Alt + S.
2. If you have a newer version of android studio, then press on app first. Then, continue with step three as follows.
3. A window will open with a bunch of options
4. Go to Flavors and that's actually all you need

You can also change the versionCode of your app there.

Here's a bash function that makes it easy to view the logs on a remote. It takes two optional arguments. The first one is the branch, it defaults to master. The second one is the remote, it defaults to staging.

git_log_remote() {
  branch=${1:-master}
  remote=${2:-staging}
  
  git fetch $remote
  git checkout $remote/$branch
  git log
  git checkout -
}

examples:

 $ git_log_remote
 $ git_log_remote development origin

ALTER TABLE GOODS MODIFY ID INT(10) NOT NULL PRIMARY KEY;

Usually, I don't care about the order of the calls, only that they happened. In that case, I combine assert_any_call with an assertion about call_count.

>>> import mock
>>> m = mock.Mock()
>>> m(1)
<Mock name='mock()' id='37578160'>
>>> m(2)
<Mock name='mock()' id='37578160'>
>>> m(3)
<Mock name='mock()' id='37578160'>
>>> m.assert_any_call(1)
>>> m.assert_any_call(2)
>>> m.assert_any_call(3)
>>> assert 3 == m.call_count
>>> m.assert_any_call(4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "[python path]\lib\site-packages\mock.py", line 891, in assert_any_call
    '%s call not found' % expected_string
AssertionError: mock(4) call not found

I find doing it this way to be easier to read and understand than a large list of calls passed into a single method.

If you do care about order or you expect multiple identical calls, assert_has_calls might be more appropriate.

Edit

Since I posted this answer, I've rethought my approach to testing in general. I think it's worth mentioning that if your test is getting this complicated, you may be testing inappropriately or have a design problem. Mocks are designed for testing inter-object communication in an object oriented design. If your design is not objected oriented (as in more procedural or functional), the mock may be totally inappropriate. You may also have too much going on inside the method, or you might be testing internal details that are best left unmocked. I developed the strategy mentioned in this method when my code was not very object oriented, and I believe I was also testing internal details that would have been best left unmocked.

Use the display: inline CSS property.

Ideal: In the stylesheet:

#container p { display: inline }

Bad/Extreme situation: Inline:

<p style="display:inline">...</p>

Workaround: This is a problem we have observed too, in Windows Server 2012 R2. I haven't found a reason or solution yet. Here is my work around.

During installation while error is shown, go to Services.msc. Find the service which throws the error, then re-enter the password in the service's log-in information. Then, hit "retry" in setup. It works.

The error will not be shown for same user again. But will be shown for a different user.

rdtsc solution did not work for me.

Firstly, I use Visual Studio 2015 Express, for which installer "modify" query does not propose any "Common Tools for Visual C++ 2015" option you could uncheck.

Secondly, even after 2 uninstall/reinstall (many hours waiting for them to complete...), the problem still remains.

I finally fixed the issue by reinstalling the whole Windows SDK from a standalone installer (independently from Visual C++ 2015 install): https://developer.microsoft.com/fr-fr/windows/downloads/windows-8-1-sdk or https://developer.microsoft.com/fr-fr/windows/downloads/windows-10-sdk

This fixed the issue for me.

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

Starting with AspNetCore 2.0, it's recommended to use ContentResult instead of the Produce attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885

This doesn't rely on serialization nor on content negotiation.

[HttpGet]
public ContentResult Index() {
    return new ContentResult {
        ContentType = "text/html",
        StatusCode = (int)HttpStatusCode.OK,
        Content = "<html><body>Hello World</body></html>"
    };
}

ArrayList is faster than LinkedList if I randomly access its elements. I think random access means "give me the nth element". Why ArrayList is faster?

ArrayList has direct references to every element in the list, so it can get the n-th element in constant time. LinkedList has to traverse the list from the beginning to get to the n-th element.

LinkedList is faster than ArrayList for deletion. I understand this one. ArrayList's slower since the internal backing-up array needs to be reallocated.

ArrayList is slower because it needs to copy part of the array in order to remove the slot that has become free. If the deletion is done using the ListIterator.remove() API, LinkedList just has to manipulate a couple of references; if the deletion is done by value or by index, LinkedList has to potentially scan the entire list first to find the element(s) to be deleted.

If it means move some elements back and then put the element in the middle empty spot, ArrayList should be slower.

Yes, this is what it means. ArrayList is indeed slower than LinkedList because it has to free up a slot in the middle of the array. This involves moving some references around and in the worst case reallocating the entire array. LinkedList just has to manipulate some references.

If you want to get stdout and stderr back (including extracting it from the CalledProcessError in the event that one occurs), use the following:

import subprocess

command = ["ls", "-l"]
try:
    output = subprocess.check_output(command, stderr=subprocess.STDOUT).decode()
    success = True 
except subprocess.CalledProcessError as e:
    output = e.output.decode()
    success = False

print(output)

This is Python 2 and 3 compatible.

If your command is a string rather than an array, prefix this with:

import shlex
command = shlex.split(command)

ddList.Items.FindByText("oldValue").Selected = false;
ddList.Items.FindByText("newValue").Selected = true;

See: RFC 3092: Etymology of "Foo", D. Eastlake 3rd et al.

Quoting only the relevant definitions from that RFC for brevity:

2. Used very generally as a sample name for absolutely anything, esp. programs and files (esp. scratch files).

3. First on the standard list of metasyntactic variables used in syntax examples (bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, thud). [JARGON]

The bash script "corstest" below works for me. It is based on Jun's comment above.

For me the problem was a wrong include directory. I have no idea why this caused the error with the seemingly missing lib as the include directory only contains the header files. And the library directory had the correct path set.

For SQL Server 2008

SELECT email,
       CASE
         WHEN EXISTS(SELECT *
                     FROM   Users U
                     WHERE  E.email = U.email) THEN 'Exist'
         ELSE 'Not Exist'
       END AS [Status]
FROM   (VALUES('email1'),
              ('email2'),
              ('email3'),
              ('email4')) E(email)  

For previous versions you can do something similar with a derived table UNION ALL-ing the constants.

/*The SELECT list is the same as previously*/
FROM (
SELECT 'email1' UNION ALL
SELECT 'email2' UNION ALL
SELECT 'email3' UNION ALL
SELECT 'email4'
)  E(email)

Or if you want just the non-existing ones (as implied by the title) rather than the exact resultset given in the question, you can simply do this

SELECT email
FROM   (VALUES('email1'),
              ('email2'),
              ('email3'),
              ('email4')) E(email)  
EXCEPT
SELECT email
FROM Users

other way(unicode string even):

$res = array();
$str = 'test 1234 555 2.7 string ..... 2.2 3.3';
$str = preg_replace("/[^0-9\.]/", " ", $str);
$str = trim(preg_replace('/\s+/u', ' ', $str));
$arr = explode(' ', $str);
for ($i = 0; $i < count($arr); $i++) {
    if (is_numeric($arr[$i])) {
        $res[] = $arr[$i];
    }
}
print_r($res); //Array ( [0] => 1234 [1] => 555 [2] => 2.7 [3] => 2.2 [4] => 3.3 ) 

Not gonna happen with CSS only

Inline javascript

<a href='index.html' 
    onmouseover='this.style.textDecoration="none"' 
    onmouseout='this.style.textDecoration="underline"'>
    Click Me
</a>

In a working draft of the CSS2 spec it was declared that you could use pseudo-classes inline like this:

<a href="http://www.w3.org/Style/CSS"
   style="{color: blue; background: white}  /* a+=0 b+=0 c+=0 */
      :visited {color: green}           /* a+=0 b+=1 c+=0 */
      :hover {background: yellow}       /* a+=0 b+=1 c+=0 */
      :visited:hover {color: purple}    /* a+=0 b+=2 c+=0 */
     ">
</a>

but it was never implemented in the release of the spec as far as I know.

You can add a class to the button and put some script redirecting it.

I do it this way:

<button class='buttonClass'>button name</button>

<script>
$(".buttonClass').click(function(){
window.location.href = "http://stackoverflow.com";
});
</script>

To decode:

byte[] image = Base64.getDecoder().decode(base64string);

To encode:

String text = Base64.getEncoder().encodeToString(imageData);

You CAN do this with gradle. I've made a demo project showing how.

The trick is to use gradle's ability to merge multiple resource folders, and set the res folder as well as the nested subfolders in the sourceSets block.

The quirk is that you can't declare a container resource folder before you declare that folder's child resource folders.

Below is the sourceSets block from the build.gradle file from the demo. Notice that the subfolders are declared first.

sourceSets {
    main {
        res.srcDirs =
        [
                'src/main/res/layouts/layouts_category2',
                'src/main/res/layouts',
                'src/main/res'
        ]
    }
}

Also, the direct parent of your actual resource files (pngs, xml layouts, etc..) does still need to correspond with the specification.

To compile TensorFlow with SSE4.2 and AVX, you can use directly

bazel build --config=mkl --config="opt" --copt="-march=broadwell" --copt="-O3" //tensorflow/tools/pip_package:build_pip_package

Source: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/tools/docker/Dockerfile.devel-cpu-mkl

To update a subset of fields, you can use update_fields:

survey.save(update_fields=["active"]) 

The update_fields argument was added in Django 1.5. In earlier versions, you could use the update() method instead:

Survey.objects.filter(pk=survey.pk).update(active=True)

Because C, where the concept originated, is 30 years old, and back then, it was the only viable way to link together code from multiple files.

Today, it's an awful hack which totally destroys compilation time in C++, causes countless needless dependencies (because class definitions in a header file expose too much information about the implementation), and so on.

first select datagrid and then go to properties find Datagrid_AutoGeneratingColumn and the double click And then use this code

   Datagrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
            {
                if (e.PropertyName == "Your column name")
                    (e.Column as DataGridTextColumn).Binding.StringFormat = "dd/MMMMMMMMM/yyyy";
                if (e.PropertyName == "Your column name")
                    (e.Column as DataGridTextColumn).Binding.StringFormat = "dd/MMMMMMMMM/yyyy";
            }

}

you can check this code . i hope you will easily understand.

If by binary you mean bytes type, you can just use encode method of the string object that encodes your string as a bytes object using the passed encoding type. You just need to make sure you pass a proper encoding to encode function.

In [9]: "hello world".encode('ascii')                                                                                                                                                                       
Out[9]: b'hello world'

In [10]: byte_obj = "hello world".encode('ascii')                                                                                                                                                           

In [11]: byte_obj                                                                                                                                                                                           
Out[11]: b'hello world'

In [12]: byte_obj[0]                                                                                                                                                                                        
Out[12]: 104

Otherwise, if you want them in form of zeros and ones --binary representation-- as a more pythonic way you can first convert your string to byte array then use bin function within map :

>>> st = "hello world"
>>> map(bin,bytearray(st))
['0b1101000', '0b1100101', '0b1101100', '0b1101100', '0b1101111', '0b100000', '0b1110111', '0b1101111', '0b1110010', '0b1101100', '0b1100100']
 

Or you can join it:

>>> ' '.join(map(bin,bytearray(st)))
'0b1101000 0b1100101 0b1101100 0b1101100 0b1101111 0b100000 0b1110111 0b1101111 0b1110010 0b1101100 0b1100100'

Note that in python3 you need to specify an encoding for bytearray function :

>>> ' '.join(map(bin,bytearray(st,'utf8')))
'0b1101000 0b1100101 0b1101100 0b1101100 0b1101111 0b100000 0b1110111 0b1101111 0b1110010 0b1101100 0b1100100'

You can also use binascii module in python 2:

>>> import binascii
>>> bin(int(binascii.hexlify(st),16))
'0b110100001100101011011000110110001101111001000000111011101101111011100100110110001100100'

hexlify return the hexadecimal representation of the binary data then you can convert to int by specifying 16 as its base then convert it to binary with bin.

It's important to point out to readers stumbling upon this question when researching the subject in a broader fashion that the accepted answer's procedure is not required in the case you just want to split your project into files. It's only needed when you need multiple implementations of single classes. If your implementation per class is one, just one header file for each is enough.

Hence, from the accepted answer's example only this part is needed:

#ifndef MYHEADER_H
#define MYHEADER_H

//Class goes here, full declaration AND implementation

#endif

The #ifndef etc. preprocessor definitions allow it to be used multiple times.

PS. The topic becomes clearer once you realize C/C++ is 'dumb' and #include is merely a way to say "dump this text at this spot".

You can optionally overload the = operator for the variable and can put the breakpoint inside the overloaded function on specific condition.

Permanent:

UPDATE
  MyTable
SET
  MyColumn = UPPER(MyColumn)

Temporary:

SELECT
  UPPER(MyColumn) AS MyColumn
FROM
  MyTable

In App.config:

<add key="YOURKEY" value="a,b,c"/>

In C#:

string[] InFormOfStringArray = ConfigurationManager.AppSettings["YOURKEY"].Split(',').Select(s => s.Trim()).ToArray();
List<string> list = new List<string>(InFormOfStringArray);

You could use moment.js with Postman to give you that timestamp format.

You can add this to the pre-request script:

const moment = require('moment');
pm.globals.set("today", moment().format("MM/DD/YYYY"));

Then reference {{today}} where ever you need it.

If you add this to the Collection Level Pre-request Script, it will be run for each request in the Collection. Rather than needing to add it to all the requests individually.

For more information about using moment in Postman, I wrote a short blog post: https://dannydainton.com/2018/05/21/hold-on-wait-a-moment/

I needed to see the results of this script and was able to do so by incorporating the below:

var i=0;

function increase()
{
i++;
document.getElementById('boldstuff').innerHTML= +i;
}

<p>var = <b id="boldstuff">0</b></p>
<input type="button" onclick="increase();">

add the "script" tag above all and a closing script tag below the function end curly brace. Returning false caused firefox to hang when I tried it. All other solutions didn't show the result of the increment, in my experience.

There are several ways to reload the current page using a button or other trigger. The examples below use a button click to reload the page but you can use a text hyperlink or any trigger you like.

<input type="button" value="Reload Page" onClick="window.location.reload()">

<input type="button" value="Reload Page" onClick="history.go(0)">

<input type="button" value="Reload Page" onClick="window.location.href=window.location.href">

I'd think some datbases can import data from CSV (comma separated values) files, wich you can export from exel. Or at least it's quite easy to use a csv parser (find one for your language, don't try to create one yourself - it's harder than it looks) to import it to the database.

I'm not familiar with MS SQL but it wouldn't suprise me if it does support it directly.

In any case I think the requrement must be that the structure in the Exel sheet and the database table is similar.

Inspired by TheIT, I just got this to work by manipulating the manifest file but in a slightly different fashion. Set the icon in the application setting so that the majority of the activities get the icon. On the activity where you want to show the logo, add the android:logo attribute to the activity declaration. In the following example, only LogoActivity should have the logo, while the others will default to icon.

<application
    android:name="com.your.app"
    android:icon="@drawable/your_icon"
    android:label="@string/app_name">

    <activity
        android:name="com.your.app.LogoActivity"
        android:logo="@drawable/your_logo"
        android:label="Logo Activity" >

    <activity
        android:name="com.your.app.IconActivity1"
        android:label="Icon Activity 1" >

    <activity
        android:name="com.your.app.IconActivity2"
        android:label="Icon Activity 2" >

</application>

Hope this helps someone else out!

If you want to load csv as a dataframe then you can do the following:

from pyspark.sql import SQLContext
sqlContext = SQLContext(sc)

df = sqlContext.read.format('com.databricks.spark.csv') \
    .options(header='true', inferschema='true') \
    .load('sampleFile.csv') # this is your csv file

It worked fine for me.

var user = "your name";
var s = 'hello ' + user + ', how are you doing';

You can also use:

Dim strPath As String = AppDomain.CurrentDomain.BaseDirectory

Try like this:

if message.value[0] == "/" or message.value[0] == "\\":
  do_stuff

This can be solved also by izipping the dataframe (iterator) with an offset version of itself.

Of course the indexing error cannot be reproduced this way.

Check this out

import pandas as pd
from itertools import izip

df = pd.DataFrame(['AA', 'BB', 'CC'], columns = ['value'])   

for id1, id2 in izip(df.iterrows(),df.ix[1:].iterrows()):
    print id1[1]['value']
    print id2[1]['value']

which gives

AA
BB
BB
CC

If you put the ; symbol, this action inactive the extension.

I had the same problem and did the following:

1. Uninstall php with purge parameter:

   sudo apt-get --purge remove php5-common
   

2. And install again:

   sudo apt-get install php5 php5-mysql
   

like this?

doc.addEeventListener("touchstart", function(){
    // your code ...
}, false);    

You need to add

#container
{
    display:inline-block;
    position:relative;
    background:rgb(255,100,0);
    margin:0px;
    width:40%;
    height:100px;
    margin-right:-4px;
}

because whenever you write display:inline-block it takes an additional margin-right:4px. So, you need to remove it.

I think I got there in the end.

The task is like this:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
  with_items: "{{ people.results }}"

It loops through each of the dicts (item) in the people.results array, each time creating a new dict like {Bob: "male"}, and combine()s that new dict in the genders array, which ends up like:

{
    "Bob": "male",
    "Thelma": "female"
}

It assumes the keys (the name in this case) will be unique.

I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
  with_items: "{{ people.results }}"

This keeps combining the existing list with a list containing a single dict. We end up with a genders array like this:

[
    {'name': 'Bob', 'gender': 'male'},
    {'name': 'Thelma', 'gender': 'female'}
]

It sounds like you should be clearer about your RNG requirements. The strongest cryptographic RNG requirement (as I understand it) would be that even if you know the algorithm used to generate them, and you know all previously generated random numbers, you could not get any useful information about any of the random numbers generated in the future, without spending an impractical amount of computing power.

If you don't need this full guarantee of randomness then there are probably appropriate performance tradeoffs. I would tend to agree with Dan Dyer's response about AESCounterRNG from Uncommons-Maths, or Fortuna (one of its authors is Bruce Schneier, an expert in cryptography). I've never used either but the ideas appear reputable at first glance.

I would think that if you could generate an initial random seed periodically (e.g. once per day or hour or whatever), you could use a fast stream cipher to generate random numbers from successive chunks of the stream (if the stream cipher uses XOR then just pass in a stream of nulls or grab the XOR bits directly). ECRYPT's eStream project has lots of good information including performance benchmarks. This wouldn't maintain entropy between the points in time that you replenish it, so if someone knew one of the random numbers and the algorithm you used, technically it might be possible, with a lot of computing power, to break the stream cipher and guess its internal state to be able to predict future random numbers. But you'd have to decide whether that risk and its consequences are sufficient to justify the cost of maintaining entropy.

Edit: here's some cryptographic course notes on RNG I found on the 'net that look very relevant to this topic.

Your first problem was you weren't using your compare symbols correctly.

To answer your other questions; get the condition to work on every cell in the column and what about blanks?

What about blanks?

Add an extra IF condition to check if the cell is blank or not, if it isn't blank perform the check. =IF(B2="","",B2<=TODAY())

Condition on every cell in column

I use templates for long text:

email-template.txt contains

hello {name}!
how are you? 

In PHP I do this:

$email = file_get_contents('email-template.txt');
$email = str_replace('{name},', 'Simon', $email);

 "foobar".gsub(/(o+)/){|s|s+'ball'}
 #=> "fooballbar"

I had the very same issue running Jupyter. After chasing my tail on permissions, I found that everything cleared up after I changed ownership on the directory where I was trying to run/store my notebooks. Ex.: I was running my files out of my ~/bash dir. That was root:root; when I changed it to jim:jim....no more errors.

Here are a few more tips:

• In Arch Linux the global one is at /etc/vimrc. There are some comments in there with helpful details.

• Since the filename starts with a ., it's hidden unless you use ls -a to show ALL files.

• Typing :version while in Vim will show you a bunch of interesting information including the file location.

• If you're not sure what ~/.vimrc means look at this question.

Classically, ~/.profile is used by Bourne Shell, and is probably supported by Bash as a legacy measure. Again, ~/.login and ~/.cshrc were used by C Shell - I'm not sure that Bash uses them at all.

The ~/.bash_profile would be used once, at login. The ~/.bashrc script is read every time a shell is started. This is analogous to /.cshrc for C Shell.

One consequence is that stuff in ~/.bashrc should be as lightweight (minimal) as possible to reduce the overhead when starting a non-login shell.

I believe the ~/.environment file is a compatibility file for Korn Shell.

To auto-format the selection, use ?K ?F (the trick is that this is to be done in sequence, ?K first, followed by ?F).

To just indent (shift right) without auto-formatting, use ?]

sns.boxplot() function returns Axes(matplotlib.axes.Axes) object. please refer the documentation you can add title using 'set' method as below:

sns.boxplot('Day', 'Count', data=gg).set(title='lalala')

you can also add other parameters like xlabel, ylabel to the set method.

sns.boxplot('Day', 'Count', data=gg).set(title='lalala', xlabel='its x_label', ylabel='its y_label')

There are some other methods as mentioned in the matplotlib.axes.Axes documentaion to add tile, legend and labels.

For anyone looking to do something similar using a reader with the stored procedure, note that the reader must be closed to retrieve the output value.

using (SqlConnection conn = new SqlConnection())
{
    SqlCommand cmd = new SqlCommand("sproc", conn);
    cmd.CommandType = CommandType.StoredProcedure;

    // add parameters
    SqlParameter outputParam = cmd.Parameters.Add("@ID", SqlDbType.Int);
    outputParam.Direction = ParameterDirection.Output;

    conn.Open();

    using(IDataReader reader = cmd.ExecuteReader())
    {
        while(reader.Read())
        {
            //read in data
        }
    }
    // reader is closed/disposed after exiting the using statement
    int id = outputParam.Value;
}

Tried this on firefox, works http://jsfiddle.net/Tm26Q/1/

$(function(){
 /** Just to mimic a blinking box on the page**/
  setInterval(function(){$("div#box").hide();},2001);
  setInterval(function(){$("div#box").show();},1000);
 /**/
});

$("div#box").on("DOMAttrModified",
function(){if($(this).is(":visible"))console.log("visible");});

UPDATE

Currently the Mutation Events (like DOMAttrModified used in the solution) are replaced by MutationObserver, You can use that to detect DOM node changes like in the above case.

For the most part recursion is slower, and takes up more of the stack as well. The main advantage of recursion is that for problems like tree traversal it make the algorithm a little easier or more "elegant". Check out some of the comparisons:

Different approaches and different strategies. In my case I could not find the window of my dialog either through using VisualTreeHelper or extension methods from Telerik to find parent of given type. Instead, I found my my dialog view which accepts custom injection of contents using Application.Current.Windows.

public Window GetCurrentWindowOfType<TWindowType>(){
 return Application.Current.Windows.OfType<TWindowType>().FirstOrDefault() as Window;
}

You can do this by registering an event handler on the document or any element you want to observe keystrokes on and examine the key related properties of the event object.

Example that works in FF and Webkit-based browsers:

document.addEventListener('keydown', function(event) {
    if(event.keyCode == 37) {
        alert('Left was pressed');
    }
    else if(event.keyCode == 39) {
        alert('Right was pressed');
    }
});

DEMO

I'm going to be brave and throw my hat into the ring on this one (ancient as it is), see how many downvotes I can collect.

Here is my attempt, which does seem to work everywhere I have tested it (Chrome20, IE8 and FF14):

(function() {
    if (top == self) {
        return;
    }

    setInterval(function() {
        top.location.replace(document.location);
        setTimeout(function() {
            var xhr = new XMLHttpRequest();
            xhr.open(
                'get',
                'http://mysite.tld/page-that-takes-a-while-to-load',
                false
            );
            xhr.send(null);
        }, 0);
    }, 1);
}());

I placed this code in the <head> and called it from the end of the <body> to ensure my page is rendered before it starts arguing with the malicious code, don't know if this is the best approach, YMMV.

How does it work?

...I hear you ask - well the honest answer is, I don't really know. It took a lot of fudging about to make it work everywhere I was testing, and the exact effect that it has varies slightly depending on where you run it.

Here is the thinking behind it:

• Set a function to run at the lowest possible interval. The basic concept behind any of the realistic solutions I have seen is to fill up the scheduler with more events than the frame buster-buster has.
• Every time the function fires, try and change the location of the top frame. Fairly obvious requirement.
• Also schedule a function to run immediately which will take a long time to complete (thereby blocking the frame buster-buster from interfering with the location change). I chose a synchronous XMLHttpRequest because it's the only mechanism I can think of that doesn't require (or at least ask for) user interaction and doesn't chew up the user's CPU time.

For my http://mysite.tld/page-that-takes-a-while-to-load (the target of the XHR) I used a PHP script that looks like this:

<?php sleep(5);

What happens?

• Chrome and Firefox wait the 5 seconds while the XHR completes, then successfully redirect to the framed page's URL.
• IE redirects pretty much immediately

Can't you avoid the wait time in Chrome and Firefox?

Apparently not. At first I pointed the XHR to a URL that would return a 404 - this didn't work in Firefox. Then I tried the sleep(5); approach that I eventually landed on for this answer, then I started playing around with the sleep length in various ways. I could find no real pattern to the behaviour, but I did find that if it is too short, specifically Firefox will not play ball (Chrome and IE seem to be fairly well behaved). I don't know what the definition of "too short" is in real terms, but 5 seconds seems to work every time.

If any passing Javascript ninjas want to explain a little better what's going on, why this is (probably) wrong, unreliable, the worst code they've ever seen etc I'll happily listen.

Assuming a simple case, where your field is public:

List list; // from your method
for(Object x : list) {
    Class<?> clazz = x.getClass();
    Field field = clazz.getField("fieldName"); //Note, this can throw an exception if the field doesn't exist.
    Object fieldValue = field.get(x);
}

But this is pretty ugly, and I left out all of the try-catches, and makes a number of assumptions (public field, reflection available, nice security manager).

If you can change your method to return a List<Foo>, this becomes very easy because the iterator then can give you type information:

List<Foo> list; //From your method
for(Foo foo:list) {
    Object fieldValue = foo.fieldName;
}

Or if you're consuming a Java 1.4 interface where generics aren't available, but you know the type of the objects that should be in the list...

List list;
for(Object x: list) {
   if( x instanceof Foo) {
      Object fieldValue = ((Foo)x).fieldName;
   }
}

No reflection needed :)

See the original markdown specification (bold mine):

The implication of the “one or more consecutive lines of text” rule is that Markdown supports “hard-wrapped” text paragraphs. This differs significantly from most other text-to-HTML formatters (including Movable Type’s “Convert Line Breaks” option) which translate every line break character in a paragraph into a <br /> tag.

When you do want to insert a <br /> break tag using Markdown, you end a line with two or more spaces, then type return.

Several problems arise in this question.

Problem #1 - css Specificity (how to override important rule).

According to specification - to override this selector your selector should be 'stronger' which mean it should be!important and have at least 1 id, 1 class and something else - according to you creating this selector is impossible(as you can't alter page content). So the only possible option is to put something into element style which (could be done with js). Note: style rule should also have !important to override.

Problem #2 - background is not a single property - it is a set of properties (see specification)

So you really need to know what are exact names of properties you want to change (in your case it would be background-image)

Problem #3 - How to remove rule already applied (to get previous value)?

Unfortunately css have no mechanism to dismiss rule which qualify for an element - only to override with "stronger" rule. So you won't be able to solve this task with just setting value to something like 'inherit' or 'default' cause value you want to see is neither inherit from parent nor default. To solve this problem you have couple of options.

1) You may already know what is the value you want to apply. For example you can find out this value based on selector used. So in this case you may know that for selector ".image-list li" you need background-image: url("http://placekitten.com/150/50"). If so - just you this script:

jQuery(".image-list li").attr('style', 'background-image: url("http://placekitten.com/150/50") !important; ');

2) If you don't know the value then you can try to alter page content in such a way, that rule you want to dismiss is no longer qualify for element, whereas rule you want to be shown - still qualify. In this case you may temporary remove id from container element. Here is the code:

jQuery("#an-element").attr('id', '');
var backgroundImage = jQuery(".image-list li").css('background-image');
jQuery("#an-element").attr('id', 'an-element');
jQuery(".image-list li").attr('style', 'background-image: ' + backgroundImage + ' !important; ');

Here is link to fiddle http://jsfiddle.net/o3jn9mzo/

3) As third solution - you may generate element which will qualify for desired selection to find out property value - something like this:

var backgroundImage = jQuery("<div class='image-list'><li></li></div>").find('li').css('background-image');
jQuery(".image-list li").attr('style', 'background-image: ' + backgroundImage + ' !important; ');

P.S.: Sorry for really late response.

Using Ashley Smart logic and is being converted into Swift 4.0 and above.

    func scrollViewDidScroll(_ scrollView: UIScrollView) {
         NSObject.cancelPreviousPerformRequests(withTarget: self)
        perform(#selector(UIScrollViewDelegate.scrollViewDidEndScrollingAnimation(_:)), with: scrollView, afterDelay: 0.3)
    }

    func scrollViewDidEndScrollingAnimation(_ scrollView: UIScrollView) {
        NSObject.cancelPreviousPerformRequests(withTarget: self)
    }

The logic above solve issues such as when user is scrolling off the tableview. Without the logic, when you scroll off the tableview, didEnd will be called but it will not execute anything. Currently using it in year 2020.

How about the PATINDEX function?

The pattern matching in TSQL is not a complete regex library, but it gives you the basics.

(From Books Online)

Wildcard  Meaning  
% Any string of zero or more characters.

_ Any single character.

[ ] Any single character within the specified range 
    (for example, [a-f]) or set (for example, [abcdef]).

[^] Any single character not within the specified range 
    (for example, [^a - f]) or set (for example, [^abcdef]).

Read this documentation of moment.js here. See below example and output where I convert GMT time to local time (my zone is IST) and then I convert local time to GMT.

// convert GMT to local time
console.log('Server time:' + data[i].locationServerTime)
let serv_utc = moment.utc(data[i].locationServerTime, "YYYY-MM-DD HH:mm:ss").toDate();
console.log('serv_utc:' + serv_utc)
data[i].locationServerTime = moment(serv_utc,"YYYY-MM-DD HH:mm:ss").tz(self.zone_name).format("YYYY-MM-DD HH:mm:ss");
console.log('Converted to local time:' + data[i].locationServerTime)

// convert local time to GMT
console.log('local time:' + data[i].locationServerTime)
let serv_utc = moment(data[i].locationServerTime, "YYYY-MM-DD HH:mm:ss").toDate();
console.log('serv_utc:' + serv_utc)
data[i].locationServerTime = moment.utc(serv_utc,"YYYY-MM-DD HH:mm:ss").format("YYYY-MM-DD HH:mm:ss");
console.log('Converted to server time:' + data[i].locationServerTime)

Output is

I liked Lukasz version, but since urllib and urllparse functions are somewhat awkward to use in this case, I think it's more straightforward to do something like this:

params = urllib.urlencode(params)

if urlparse.urlparse(url)[4]:
    print url + '&' + params
else:
    print url + '?' + params

In straight-up computer programming, there is no such thing as "printing bold text". Let's back up a bit and understand that your text is a string of bytes and bytes are just bundles of bits. To the computer, here's your "hello" text, in binary.

0110100001100101011011000110110001101111

Each one or zero is a bit. Every eight bits is a byte. Every byte is, in a string like that in Python 2.x, one letter/number/punctuation item (called a character). So for example:

01101000 01100101 01101100 01101100 01101111
h        e        l        l        o

The computer translates those bits into letters, but in a traditional string (called an ASCII string), there is nothing to indicate bold text. In a Unicode string, which works a little differently, the computer can support international language characters, like Chinese ones, but again, there's nothing to say that some text is bold and some text is not. There's also no explicit font, text size, etc.

In the case of printing HTML, you're still outputting a string. But the computer program reading that string (a web browser) is programmed to interpret text like this is <b>bold</b> as "this is bold" when it converts your string of letters into pixels on the screen. If all text were WYSIWYG, the need for HTML itself would be mitigated -- you would just select text in your editor and bold it instead of typing out the HTML.

Other programs use different systems -- a lot of answers explained a completely different system for printing bold text on terminals. I'm glad you found out how to do what you want to do, but at some point, you'll want to understand how strings and memory work.

Here's one way:

SELECT 
     sysobjects.name AS trigger_name 
    ,USER_NAME(sysobjects.uid) AS trigger_owner 
    ,s.name AS table_schema 
    ,OBJECT_NAME(parent_obj) AS table_name

FROM sysobjects 

INNER JOIN sysusers 
    ON sysobjects.uid = sysusers.uid 

INNER JOIN sys.tables t 
    ON sysobjects.parent_obj = t.object_id 

INNER JOIN sys.schemas s 
    ON t.schema_id = s.schema_id 

WHERE sysobjects.type = 'TR' 

EDIT: Commented out join to sysusers for query to work on AdventureWorks2008.

    ON sysobjects.parent_obj = t.object_id

WHERE o.type = 'TR'

First you need to input the two numbers say num_rows and num_columns perhaps using argc and argv then do a for loop to print the dots.

int j=0;
int k=0;
for (k=0;k<num_columns;k++){
   for (j=0;j<num_rows;j++){
       printf(".");
   }
 printf("\n");
 }

you'd have to replace the dot with something else later.

Open up a command prompt and type java -jar jbpm-installer-3.2.7.jar

$("#togglebutton").click(function () {
  $(".fa-arrow-circle-left").toggleClass("fa-arrow-circle-right");
}

I have a button with the id "togglebutton" and an icon from FontAwesome . This can be a way to toggle it . from left arrow to right arrow icon

If you don't care about this question being specifically about a tableview, and you'd just like to center one view on top of another view here's to do it:

    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterX, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterX, multiplier: 1, constant: 0)
    parentView.addConstraint(horizontalConstraint)

    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0)
    parentView.addConstraint(verticalConstraint)

I found this really helpful answer here.

rsync -r -v --progress -e ssh user@remote-system:/address/to/remote/file /home/user/

Not only you can pass there the password, but also it will show the progress bar when copying. Really awesome.

Configure the pivot table so that it is like this:

Your code can simply work on range("B1") now and the pivot table will be filtered to you required SavedFamilyCode

Sub FilterPivotTable()
Application.ScreenUpdating = False
    ActiveSheet.Range("B1") = "K123224"
Application.ScreenUpdating = True
End Sub

length and dbms_lob.getlength return the number of characters when applied to a CLOB (Character LOB). When applied to a BLOB (Binary LOB), dbms_lob.getlength will return the number of bytes, which may differ from the number of characters in a multi-byte character set.

As the documentation doesn't specify what happens when you apply length on a BLOB, I would advise against using it in that case. If you want the number of bytes in a BLOB, use dbms_lob.getlength.

Here's the answer to all your questions: http://wiki.python.org/moin/PythonEditors

A solution with works with Python 2.X and Python 3.X makes use of the Python 2 and 3 compatibility library six:

from six.moves.urllib.request import urlopen
link = "http://www.somesite.com/details.pl?urn=2344"
response = urlopen(link)
content = response.read()
print(content)

I found this:

<embed type="application/x-vlc-plugin"
pluginspage="http://www.videolan.org"version="VideoLAN.VLCPlugin.2"  width="100%"        
height="100%" id="vlc" loop="yes"autoplay="yes" target="http://10.1.2.201:8000/"></embed>

I don't see that in your code anywhere.... I think that's all you need and the target would be the location of your video...

and here is more info on the vlc plugin:
http://wiki.videolan.org/Documentation%3aWebPlugin#Input_object

Another thing to check is that the address for the video file is correct....

The following solution works with python 3 only, but for me it looks most clear.

The idea is to use log record factory to add 'colored' attributes to log record objects and than use these 'colored' attributes in log format.

import logging
logger = logging.getLogger(__name__)

def configure_logging(level):

    # add 'levelname_c' attribute to log resords
    orig_record_factory = logging.getLogRecordFactory()
    log_colors = {
        logging.DEBUG:     "\033[1;34m",  # blue
        logging.INFO:      "\033[1;32m",  # green
        logging.WARNING:   "\033[1;35m",  # magenta
        logging.ERROR:     "\033[1;31m",  # red
        logging.CRITICAL:  "\033[1;41m",  # red reverted
    }
    def record_factory(*args, **kwargs):
        record = orig_record_factory(*args, **kwargs)
        record.levelname_c = "{}{}{}".format(
            log_colors[record.levelno], record.levelname, "\033[0m")
        return record

    logging.setLogRecordFactory(record_factory)

    # now each log record object would contain 'levelname_c' attribute
    # and you can use this attribute when configuring logging using your favorite
    # method.
    # for demo purposes I configure stderr log right here

    formatter_c = logging.Formatter("[%(asctime)s] %(levelname_c)s:%(name)s:%(message)s")

    stderr_handler = logging.StreamHandler()
    stderr_handler.setLevel(level)
    stderr_handler.setFormatter(formatter_c)

    root_logger = logging.getLogger('')
    root_logger.setLevel(logging.DEBUG)
    root_logger.addHandler(stderr_handler)


def main():
    configure_logging(logging.DEBUG)

    logger.debug("debug message")
    logger.info("info message")
    logger.critical("something unusual happened")


if __name__ == '__main__':
    main()

You can easily modify this example to create other colored attributes (f.e. message_c) and then use these attributes to get colored text (only) where you want.

(handy trick I discovered recently: I have a file with colored debug logs and whenever I want temporary increase the log level of my application I just tail -f the log file in different terminal and see debug logs on screen w/o changing any configuration and restarting application)

https://github.com/john-kurkowski/tldextract

This is a more verbose version of urlparse. It detects domains and subdomains for you.

From their documentation:

>>> import tldextract
>>> tldextract.extract('http://forums.news.cnn.com/')
ExtractResult(subdomain='forums.news', domain='cnn', suffix='com')
>>> tldextract.extract('http://forums.bbc.co.uk/') # United Kingdom
ExtractResult(subdomain='forums', domain='bbc', suffix='co.uk')
>>> tldextract.extract('http://www.worldbank.org.kg/') # Kyrgyzstan
ExtractResult(subdomain='www', domain='worldbank', suffix='org.kg')

ExtractResult is a namedtuple, so it's simple to access the parts you want.

>>> ext = tldextract.extract('http://forums.bbc.co.uk')
>>> ext.domain
'bbc'
>>> '.'.join(ext[:2]) # rejoin subdomain and domain
'forums.bbc'

And if you don't want to use the entire framework like Express, but you also need different kinds of forms, including uploads, then formaline may be a good choice.

It is listed in Node.js modules

It might be not direct solution, but I've created a lib that allows you to use 3 fingers touch instead of shake to open dev menu, when in development mode

https://github.com/pie6k/react-native-dev-menu-on-touch

You only have to wrap your app inside:

import DevMenuOnTouch from 'react-native-dev-menu-on-touch'; // or: import { DevMenuOnTouch } from 'react-native-dev-menu-on-touch'

class YourRootApp extends Component {
  render() {
    return (
      <DevMenuOnTouch>
        <YourApp />
      </DevMenuOnTouch>
    );
  }
}

It's really useful when you have to debug on real device and you have co-workers sitting next to you.

Copy this piece of code and run it to find out.

<?php
 if(!function_exists('apache_get_modules') ){ phpinfo(); exit; }
 $res = 'Module Unavailable';
 if(in_array('mod_rewrite',apache_get_modules())) 
 $res = 'Module Available';
?>
<html>
<head>
<title>A mod_rewrite availability check !</title></head>
<body>
<p><?php echo apache_get_version(),"</p><p>mod_rewrite $res"; ?></p>
</body>
</html>

If you are looking to remove usernames and passwords from your docker-compose.yml you can use Docker Secrets, here is how I have approached it.

version: '3.6'

services:
  db:
    image: mongo:3
    container_name: mycontainer
  secrets:
    - MONGO_INITDB_ROOT_USERNAME
    - MONGO_INITDB_ROOT_PASSWORD
  environment:
    - MONGO_INITDB_ROOT_USERNAME_FILE=/var/run/secrets/MONGO_INITDB_ROOT_USERNAME
    - MONGO_INITDB_ROOT_PASSWORD_FILE=/var/run/secrets/MONGO_INITDB_ROOT_PASSWORD
secrets:
  MONGO_INITDB_ROOT_USERNAME:
    file:  secrets/${NODE_ENV}_mongo_root_username.txt
  MONGO_INITDB_ROOT_PASSWORD:
    file:  secrets/${NODE_ENV}_mongo_root_password.txt

I have use the file: option for my secrets however, you can also use external: and use the secrets in a swarm.

The secrets are available to any script in the container at /var/run/secrets

The Docker documentation has this to say about storing sensitive data...

https://docs.docker.com/engine/swarm/secrets/

You can use secrets to manage any sensitive data which a container needs at runtime but you don’t want to store in the image or in source control, such as:

Usernames and passwords TLS certificates and keys SSH keys Other important data such as the name of a database or internal server Generic strings or binary content (up to 500 kb in size)

Here is the best method that I've found: First, set your projects output type to "Windows Application", then P/Invoke AllocConsole to create a console window.

internal static class NativeMethods
{
    [DllImport("kernel32.dll")]
    internal static extern Boolean AllocConsole();
}

static class Program
{

    static void Main(string[] args) {
        if (args.Length == 0) {
            // run as windows app
            Application.EnableVisualStyles();
            Application.Run(new Form1()); 
        } else {
            // run as console app
            NativeMethods.AllocConsole();
            Console.WriteLine("Hello World");
            Console.ReadLine();
        }
    }

}

This seemed to work pretty well for me.

private DataTable ReadExcelFile(string sheetName, string path)
{

    using (OleDbConnection conn = new OleDbConnection())
    {
        DataTable dt = new DataTable();
        string Import_FileName = path;
        string fileExtension = Path.GetExtension(Import_FileName);
        if (fileExtension == ".xls")
            conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Import_FileName + ";" + "Extended Properties='Excel 8.0;HDR=YES;'";
        if (fileExtension == ".xlsx")
            conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Import_FileName + ";" + "Extended Properties='Excel 12.0 Xml;HDR=YES;'";
        using (OleDbCommand comm = new OleDbCommand())
        {
            comm.CommandText = "Select * from [" + sheetName + "$]";
            comm.Connection = conn;
            using (OleDbDataAdapter da = new OleDbDataAdapter())
            {
                da.SelectCommand = comm;
                da.Fill(dt);
                return dt;
            }
        }
    }
}

here is an example

 <a class="facultySelecter" data-faculty="ahs" href="#">Arts and Human Sciences</a></li>

    $('.facultySelecter').click(function() {        
    var unhide = $(this).data("faculty");
    });

this would set var unhide as ahs, so use .data("foo") to get the "foo" value of the data-* attribute you're looking to get

Not sure this is the best way, but you can certainly replace the tick labels like this:

import matplotlib.pyplot as plt
x = range(10)
y = range(10)
plt.plot(x,y)
plt.xticks(x," ")
plt.show()

In Python 3.4 this generates a simple line plot with no tick labels on the x-axis. A simple example is here: http://matplotlib.org/examples/ticks_and_spines/ticklabels_demo_rotation.html

This related question also has some better suggestions: Hiding axis text in matplotlib plots

I'm new to python. Your mileage may vary in earlier versions. Maybe others can help?

Consider this to get a fully unique jar file:

• GroupID - com.companyname.project
• ArtifactId - com-companyname-project
• Package - com.companyname.project

The FASTEST way, to see all parents, and IN ORDER, just use the built in __mro__

i.e. repr(YOUR_CLASS.__mro__)

>>>
>>>
>>> import getpass
>>> getpass.GetPassWarning.__mro__

outputs, IN ORDER

(<class 'getpass.GetPassWarning'>, <type 'exceptions.UserWarning'>,
<type 'exceptions.Warning'>, <type 'exceptions.Exception'>, 
<type 'exceptions.BaseException'>, <type 'object'>)
>>>

There you have it. The "best" answer right now, has 182 votes (as I am typing this) but this is SO much simpler than some convoluted for loop, looking into bases one class at a time, not to mention when a class extends TWO or more parent classes. Importing and using inspect just clouds the scope unnecessarily. It honestly is a shame people don't know to just use the built-ins

I Hope this Helps!

Given

Dynamically added items have to be added to the DOM... clone().append() adds it to the DOM... which allows it to be selected via jquery.

1. First try npm install ,if the issue is not yet fixed try the following one after the other.
2. npm cache clean ,then
3. npm install -g npm,then npm install,Finally
4. ng serve --o to run the project. Hope this will help....

Look in the Python re documentation for lookaheads (?=...) and lookbehinds (?<=...) -- I'm pretty sure they're what you want. They match strings, but do not "consume" the bits of the strings they match.

WARNING: Old and outdated answer. Do not use

I think that you will have to go for your last solution, scraping the result page of the search, because you can only search by email with the API into those users that have authorized your APP (and you will need one because the token that FB provides in the examples has an expiry date and you need extended permissions to access the user's email).

The only approach that I have not tried, but I think it's limited in the same way, is FQL. Something like

SELECT * FROM user WHERE email '[email protected]'

file type can be checked in other ways also. I believe this is the easiest way to check the uploaded file type.. if u are dealing with an image file then go for the following code. if you are dealing with a video file then replace the image check with a video check in the if block.. have fun

     $img_up = $_FILES['video_file']['type'];
$img_up_type = explode("/", $img_up);
$img_up_type_firstpart = $img_up_type[0];

if($img_up_type_firstpart == "image") { // image is the image file type, you can deal with video if you need to check video file type
/* do your logical code */
}

Use like this on dropdown change
$("#assetgroupSelect").change(function(){
    $("#idValue").val($this.val());
})

I recommend the method given by doofledorfer.

If you really want to do it via a direct API call, then look at the OpenSCManager function. Below are sample functions to take a machine name and service, and stop or start them.

function ServiceStart(sMachine, sService : string) : boolean;  //start service, return TRUE if successful
var schm, schs : SC_Handle;
    ss         : TServiceStatus;
    psTemp     : PChar;
    dwChkP     : DWord;
begin
  ss.dwCurrentState := 0;

If the docker compose configuration is in a file, simply run:

docker-compose -f appName.yml down && docker-compose -f appName.yml pull && docker-compose -f appName.yml up -d

The JSON string will just be the body of the response you get back from the URL you have called. So add this code

...
BufferedReader in = new BufferedReader(new InputStreamReader(
                            conn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) 
    System.out.println(inputLine);
in.close();

That will allow you to see the JSON being returned to the console. The only missing piece you then have is using a JSON library to read that data and provide you with a Java representation.

Here's an example using JSON-LIB

If you can't create an locally valid security token, it seems like you've ruled all out every option bar Win32 API and WNetAddConnection*.

In simple words, dereferencing means accessing the value from a certain memory location against which that pointer is pointing.

Below is the pseudo-code for using sub-query using Criteria API.

CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery<Object> criteriaQuery = criteriaBuilder.createQuery();
Root<EMPLOYEE> from = criteriaQuery.from(EMPLOYEE.class);
Path<Object> path = from.get("compare_field"); // field to map with sub-query
from.fetch("name");
from.fetch("id");
CriteriaQuery<Object> select = criteriaQuery.select(from);

Subquery<PROJECT> subquery = criteriaQuery.subquery(PROJECT.class);
Root fromProject = subquery.from(PROJECT.class);
subquery.select(fromProject.get("requiredColumnName")); // field to map with main-query
subquery.where(criteriaBuilder.and(criteriaBuilder.equal("name",name_value),criteriaBuilder.equal("id",id_value)));

select.where(criteriaBuilder.in(path).value(subquery));

TypedQuery<Object> typedQuery = entityManager.createQuery(select);
List<Object> resultList = typedQuery.getResultList();

Also it definitely needs some modification as I have tried to map it according to your query. Here is a link http://www.ibm.com/developerworks/java/library/j-typesafejpa/ which explains concept nicely.

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

You can find the doc for the alternative syntax on PHP.net

The to_dict() method sets the column names as dictionary keys so you'll need to reshape your DataFrame slightly. Setting the 'ID' column as the index and then transposing the DataFrame is one way to achieve this.

to_dict() also accepts an 'orient' argument which you'll need in order to output a list of values for each column. Otherwise, a dictionary of the form {index: value} will be returned for each column.

These steps can be done with the following line:

>>> df.set_index('ID').T.to_dict('list')
{'p': [1, 3, 2], 'q': [4, 3, 2], 'r': [4, 0, 9]}

In case a different dictionary format is needed, here are examples of the possible orient arguments. Consider the following simple DataFrame:

>>> df = pd.DataFrame({'a': ['red', 'yellow', 'blue'], 'b': [0.5, 0.25, 0.125]})
>>> df
        a      b
0     red  0.500
1  yellow  0.250
2    blue  0.125

Then the options are as follows.

dict - the default: column names are keys, values are dictionaries of index:data pairs

>>> df.to_dict('dict')
{'a': {0: 'red', 1: 'yellow', 2: 'blue'}, 
 'b': {0: 0.5, 1: 0.25, 2: 0.125}}

list - keys are column names, values are lists of column data

>>> df.to_dict('list')
{'a': ['red', 'yellow', 'blue'], 
 'b': [0.5, 0.25, 0.125]}

series - like 'list', but values are Series

>>> df.to_dict('series')
{'a': 0       red
      1    yellow
      2      blue
      Name: a, dtype: object, 

 'b': 0    0.500
      1    0.250
      2    0.125
      Name: b, dtype: float64}

split - splits columns/data/index as keys with values being column names, data values by row and index labels respectively

>>> df.to_dict('split')
{'columns': ['a', 'b'],
 'data': [['red', 0.5], ['yellow', 0.25], ['blue', 0.125]],
 'index': [0, 1, 2]}

records - each row becomes a dictionary where key is column name and value is the data in the cell

>>> df.to_dict('records')
[{'a': 'red', 'b': 0.5}, 
 {'a': 'yellow', 'b': 0.25}, 
 {'a': 'blue', 'b': 0.125}]

index - like 'records', but a dictionary of dictionaries with keys as index labels (rather than a list)

>>> df.to_dict('index')
{0: {'a': 'red', 'b': 0.5},
 1: {'a': 'yellow', 'b': 0.25},
 2: {'a': 'blue', 'b': 0.125}}

Similiary to accepted answer what you could do is use react and react-router itself to provide you history object which you can scope in a file and then export.

history.js

import React from 'react';
import { withRouter } from 'react-router';

// variable which will point to react-router history
let globalHistory = null;

// component which we will mount on top of the app
class Spy extends React.Component {
  constructor(props) {
    super(props)
    globalHistory = props.history; 
  }

  componentDidUpdate() {
    globalHistory = this.props.history;
  }

  render(){
    return null;
  }
}

export const GlobalHistory = withRouter(Spy);

// export react-router history
export default function getHistory() {    
  return globalHistory;
}

You later then import Component and mount to initialize history variable:

import { BrowserRouter } from 'react-router-dom';
import { GlobalHistory } from './history';

function render() {
  ReactDOM.render(
    <BrowserRouter>
        <div>
            <GlobalHistory />
            //.....
        </div>
    </BrowserRouter>
    document.getElementById('app'),
  );
}

And then you can just import in your app when it has been mounted:

import getHistory from './history'; 

export const goToPage = () => (dispatch) => {
  dispatch({ type: GO_TO_SUCCESS_PAGE });
  getHistory().push('/success'); // at this point component probably has been mounted and we can safely get `history`
};

I even made and npm package that does just that.

basically set.seed() function will help to reuse the same set of random variables , which we may need in future to again evaluate particular task again with same random varibales

we just need to declare it before using any random numbers generating function.

Since Sheet.getPhysicalNumberOfRows() does not count empty rows and Sheet.getLastRowNum() returns 0 both if there is one row or no rows, I use a combination of the two methods to accurately calculate the total number of rows.

int rowTotal = sheet.getLastRowNum();

if ((rowTotal > 0) || (sheet.getPhysicalNumberOfRows() > 0)) {
    rowTotal++;
}

Note: This will treat a spreadsheet with one empty row as having none but for most purposes this is probably okay.

In your project .plist file in add this permission :

<key>NSAppTransportSecurity</key>
<dict>
    <!--Connect to anything (this is probably BAD)-->
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

Based on Jims's solution: Quick easy way to migrate SQLite3 to MySQL?

sqlite3 your_sql3_database.db .dump | python ./dump.py > your_dump_name.sql
cat your_dump_name.sql | sed '1d' | mysql --user=your_mysql_user --default-character-set=utf8 your_mysql_db -p  

This works for me. I use sed just to throw the first line, which is not mysql-like, but you might as well modify dump.py script to throw this line away.

To load your data in WebView. Call loadData() method of WebView

If you are expecting double, decimal, float, integer why not use the one which accomodates all namely decimal (128 bits are enough for most numbers you are looking at).

instead of (double)value use decimal.Parse(value.ToString()) or Convert.ToDecimal(value)

This exception only happens if you are parsing an empty String/empty byte array.

below is a snippet on how to reproduce it:

String xml = ""; // <-- deliberately an empty string.
ByteArrayInputStream xmlStream = new java.io.ByteArrayInputStream(xml.getBytes());
Unmarshaller u = JAXBContext.newInstance(...)
u.setSchema(...);
u.unmarshal( xmlStream ); // <-- here it will fail

In PostGIS, for points with latitude and longitude there is geography datatype.

To add a column:

alter table your_table add column geog geography;

To insert data:

insert into your_table (geog) values ('SRID=4326;POINT(longitude latitude)');

4326 is Spatial Reference ID that says it's data in degrees longitude and latitude, same as in GPS. More about it: http://epsg.io/4326

Order is Longitude, Latitude - so if you plot it as the map, it is (x, y).

To find closest point you need first to create spatial index:

create index on your_table using gist (geog);

and then request, say, 5 closest to a given point:

select * 
from your_table 
order by geog <-> 'SRID=4326;POINT(lon lat)' 
limit 5;

Not sure if that's exactly what are you looking for, but I did single/double taps without gesture recognizers. I'm using it in a UITableView, so I used that code in the didSelectRowAtIndexPath method

    tapCount++;
    switch (tapCount)
    {
        case 1: //single tap
            [self performSelector:@selector(singleTap:) withObject: indexPath afterDelay: 0.2];
            break;
        case 2: //double tap
            [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(singleTap:) object:indexPath];
            [self performSelector:@selector(doubleTap:) withObject: indexPath];
            break;
        default:
            break;
    }
    if (tapCount>2) tapCount=0;

Methods singleTap and doubleTap are just void with NSIndexPath as a parameter:

- (void)singleTap:(NSIndexPath *)indexPath {
  //do your stuff for a single tap
}

- (void)doubleTap:(NSIndexPath *)indexPath {
  //do your stuff for a double tap
}

Hope it helps

Adding to Greg Hewgill answer (of using core.fileMode config variable):

You can use --chmod=(-|+)x option of git update-index (low-level version of "git add") to change execute permissions in the index, from where it would be picked up if you use "git commit" (and not "git commit -a").

There are two ways to do this. The System.Diagnostics.StackTrace() will give you a stack trace for the current thread. If you have a reference to a Thread instance, you can get the stack trace for that via the overloaded version of StackTrace().

TL;DR

Consider i and n to be the left and right operands respectively of a shift operator; the type of i, after integer promotion, be T. Assuming n to be in [0, sizeof(i) * CHAR_BIT) — undefined otherwise — we've these cases:

| Direction  |   Type   | Value (i) | Result                   |
| ---------- | -------- | --------- | ------------------------ |
| Right (>>) | unsigned |    = 0    | -8 ? (i ÷ 2n)            |
| Right      | signed   |    = 0    | -8 ? (i ÷ 2n)            |
| Right      | signed   |    < 0    | Implementation-defined†  |
| Left  (<<) | unsigned |    = 0    | (i * 2n) % (T_MAX + 1)   |
| Left       | signed   |    = 0    | (i * 2n) ‡               |
| Left       | signed   |    < 0    | Undefined                |

^{† most compilers implement this as arithmetic shift
‡ undefined if value overflows the result type T; promoted type of i}

Shifting

First is the difference between logical and arithmetic shifts from a mathematical viewpoint, without worrying about data type size. Logical shifts always fills discarded bits with zeros while arithmetic shift fills it with zeros only for left shift, but for right shift it copies the MSB thereby preserving the sign of the operand (assuming a two's complement encoding for negative values).

In other words, logical shift looks at the shifted operand as just a stream of bits and move them, without bothering about the sign of the resulting value. Arithmetic shift looks at it as a (signed) number and preserves the sign as shifts are made.

A left arithmetic shift of a number X by n is equivalent to multiplying X by 2ⁿ and is thus equivalent to logical left shift; a logical shift would also give the same result since MSB anyway falls off the end and there's nothing to preserve.

A right arithmetic shift of a number X by n is equivalent to integer division of X by 2ⁿ ONLY if X is non-negative! Integer division is nothing but mathematical division and round towards 0 (trunc).

For negative numbers, represented by two's complement encoding, shifting right by n bits has the effect of mathematically dividing it by 2ⁿ and rounding towards -8 (floor); thus right shifting is different for non-negative and negative values.

for X = 0, X >> n = X / 2ⁿ = trunc(X ÷ 2ⁿ)

for X < 0, X >> n = floor(X ÷ 2ⁿ)

where ÷ is mathematical division, / is integer division. Let's look at an example:

37)₁₀ = 100101)₂

37 ÷ 2 = 18.5

37 / 2 = 18 (rounding 18.5 towards 0) = 10010)₂ [result of arithmetic right shift]

-37)₁₀ = 11011011)₂ (considering a two's complement, 8-bit representation)

-37 ÷ 2 = -18.5

-37 / 2 = -18 (rounding 18.5 towards 0) = 11101110)₂ [NOT the result of arithmetic right shift]

-37 >> 1 = -19 (rounding 18.5 towards -8) = 11101101)₂ [result of arithmetic right shift]

As Guy Steele pointed out, this discrepancy has led to bugs in more than one compiler. Here non-negative (math) can be mapped to unsigned and signed non-negative values (C); both are treated the same and right-shifting them is done by integer division.

So logical and arithmetic are equivalent in left-shifting and for non-negative values in right shifting; it's in right shifting of negative values that they differ.

Operand and Result Types

Standard C99 §6.5.7:

Each of the operands shall have integer types.

The integer promotions are performed on each of the operands. The type of the result is that of the promoted left operand. If the value of the right operand is negative or is greater than or equal to the width of the promoted left operand, the behaviour is undefined.

short E1 = 1, E2 = 3;
int R = E1 << E2;

In the above snippet, both operands become int (due to integer promotion); if E2 was negative or E2 = sizeof(int) * CHAR_BIT then the operation is undefined. This is because shifting more than the available bits is surely going to overflow. Had R been declared as short, the int result of the shift operation would be implicitly converted to short; a narrowing conversion, which may lead to implementation-defined behaviour if the value is not representable in the destination type.

Left Shift

The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1×2^E2, reduced modulo one more than the maximum value representable in the result type. If E1 has a signed type and non-negative value, and E1×2^E2 is representable in the result type, then that is the resulting value; otherwise, the behaviour is undefined.

As left shifts are the same for both, the vacated bits are simply filled with zeros. It then states that for both unsigned and signed types it's an arithmetic shift. I'm interpreting it as arithmetic shift since logical shifts don't bother about the value represented by the bits, it just looks at it as a stream of bits; but the standard talks not in terms of bits, but by defining it in terms of the value obtained by the product of E1 with 2^E2.

The caveat here is that for signed types the value should be non-negative and the resulting value should be representable in the result type. Otherwise the operation is undefined. The result type would be the type of the E1 after applying integral promotion and not the destination (the variable which is going to hold the result) type. The resulting value is implicitly converted to the destination type; if it is not representable in that type, then the conversion is implementation-defined (C99 §6.3.1.3/3).

If E1 is a signed type with a negative value then the behaviour of left shifting is undefined. This is an easy route to undefined behaviour which may easily get overlooked.

Right Shift

The result of E1 >> E2 is E1 right-shifted E2 bit positions. If E1 has an unsigned type or if E1 has a signed type and a non-negative value, the value of the result is the integral part of the quotient of E1/2^E2. If E1 has a signed type and a negative value, the resulting value is implementation-defined.

Right shift for unsigned and signed non-negative values are pretty straight forward; the vacant bits are filled with zeros. For signed negative values the result of right shifting is implementation-defined. That said, most implementations like GCC and Visual C++ implement right-shifting as arithmetic shifting by preserving the sign bit.

Conclusion

Unlike Java, which has a special operator >>> for logical shifting apart from the usual >> and <<, C and C++ have only arithmetic shifting with some areas left undefined and implementation-defined. The reason I deem them as arithmetic is due to the standard wording the operation mathematically rather than treating the shifted operand as a stream of bits; this is perhaps the reason why it leaves those areas un/implementation-defined instead of just defining all cases as logical shifts.

in javascript, object properties can be accessed with . operator or with associative array indexing using []. ie. object.property is equivalent to object["property"]

this should do the trick

var smth = mydata.list[0]["points.bean.pointsBase"][0].time;

You can try writing into the Documents folder. Here is a "debug" function I did for the debugging needs of my project:

Private Sub writeDebug(ByVal x As String)
    Dim path As String = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
    Dim FILE_NAME As String = path & "\mydebug.txt"
    MsgBox(FILE_NAME)
    If System.IO.File.Exists(FILE_NAME) = False Then
        System.IO.File.Create(FILE_NAME).Dispose()
    End If
    Dim objWriter As New System.IO.StreamWriter(FILE_NAME, True)
    objWriter.WriteLine(x)
    objWriter.Close()
End Sub

There are more standard folders you can access through the "SpecialFolder" object.

Using the solution showed in this question, System.Windows.Forms.Clipboard.SetText(...), results in the exception:

Current thread must be set to single thread apartment (STA) mode before OLE calls can be made

To prevent this, you can add the attribute:

to

static void Main(string[] args)

If you are doing something like writing HTML and Javascript in a code editor on your personal computer, and testing the output in your browser, you will probably get error messages about Cross Origin Requests. Your browser will render HTML and run Javascript, jQuery, angularJs in your browser without needing a server set up. But many web browsers are programed to watch for cross site attacks, and will block requests. You don't want just anyone being able to read your hard drive from your web browser. You can create a fully functioning web page using Notepad++ that will run Javascript, and frameworks like jQuery and angularJs; and test everything just by using the Notepad++ menu item, RUN, LAUNCH IN FIREFOX. That's a nice, easy way to start creating a web page, but when you start creating anything more than layout, css and simple page navigation, you need a local server set up on your machine.

Here are some options that I use.

1. Test your web page locally on Firefox, then deploy to your host.
2. or: Run a local server

Test on Firefox, Deploy to Host

1. Firefox currently allows Cross Origin Requests from files served from your hard drive
2. Your web hosting site will allow requests to files in folders as configured by the manifest file

Run a Local Server

• Run a server on your computer, like Apache or Python
• Python isn't a server, but it will run a simple server

Run a Local Server with Python

Get your IP address:

• On Windows: Open up the 'Command Prompt'. All Programs, Accessories, Command Prompt
• I always run the Command Prompt as Administrator. Right click the Command Prompt menu item and look for Run As Administrator
• Type the command: ipconfig and hit Enter.
• Look for: IPv4 Address . . . . . . . . 12.123.123.00
• There are websites that will also display your IP address

If you don't have Python, download and install it.

Using the 'Command Prompt' you must go to the folder where the files are that you want to serve as a webpage.

• If you need to get back to the C:\ Root directory - type cd/
• type cd Drive:\Folder\Folder\etc to get to the folder where your .Html file is (or php, etc)
• Check the path. type: path at the command prompt. You must see the path to the folder where python is located. For example, if python is in C:\Python27, then you must see that address in the paths that are listed.
• If the path to the Python directory is not in the path, you must set the path. type: help path and hit Enter. You will see help for path.
• Type something like: path c:\python27 %path%
• %path% keeps all your current paths. You don't want to wipe out all your current paths, just add a new path.
• Create the new path FROM the folder where you want to serve the files.
• Start the Python Server: Type: python -m SimpleHTTPServer port Where 'port' is the number of the port you want, for example python -m SimpleHTTPServer 1337
• If you leave the port empty, it defaults to port 8000
• If the Python server starts successfully, you will see a msg.

Run You Web Application Locally

• Open a browser
• In the address line type: http://your IP address:port
• http://xxx.xxx.x.x:1337 or http://xx.xxx.xxx.xx:8000 for the default
• If the server is working, you will see a list of your files in the browser
• Click the file you want to serve, and it should display.

More advanced solutions

• Install a code editor, web server, and other services that are integrated.

You can install Apache, PHP, Python, SQL, Debuggers etc. all separately on your machine, and then spend lots of time trying to figure out how to make them all work together, or look for a solution that combines all those things.

I like using XAMPP with NetBeans IDE. You can also install WAMP which provides a User Interface for managing and integrating Apache and other services.

This worked fine for me:

        $('#myelement').datetimepicker({
            dateFormat: "yy-mm-dd",
            timeFormat:  "hh:mm:ss"
        });

Copy your original array into another array, without the element to be removed.

A simplier way to do that is to use a List, Set... and use the remove() method.

I just found the answer and it works :)

You need to add the following to your server side link/button:

OnClientClick="aspnetForm.target ='_blank';"

My entire button code looks something like:

<asp:LinkButton ID="myButton" runat="server" Text="Click Me!" 
                OnClick="myButton_Click" 
                OnClientClick="aspnetForm.target ='_blank';"/>

In the server side OnClick I do a Response.Redirect("MyPage.aspx"); and the page is opened in a new window.

The other part you need to add is to fix the form's target otherwise every link will open in a new window. To do so add the following in the header of your POPUP window.

<script type="text/javascript">
    function fixform() {
        if (opener.document.getElementById("aspnetForm").target != "_blank") return;
        opener.document.getElementById("aspnetForm").target = "";
        opener.document.getElementById("aspnetForm").action = opener.location.href;
    }
</script>

and

<body onload="fixform()">

You can also use the required module.

require('./componentName.css');
const React = require('react');

I think I may have a better solution for having a fully responsive iframe (a vimeo video in my case) embed on your site. Nest the iframe in a div. Give them the following styles:

div {
    width: 100%;
    height: 0;
    padding-bottom: 56%; /* Change this till it fits the dimensions of your video */
    position: relative;
}

div iframe {
    width: 100%;
    height: 100%;
    position: absolute;
    display: block;
    top: 0;
    left: 0;
}

Just did it now for a client, and it seems to be working: http://themilkrunsa.co.za/

Please try this

SELECT *
FROM   [Village]
WHERE  CONVERT(VARCHAR, CastleType) = 'foo'

for (var i in conf) {
  val = conf[i];
  console.log(val.path);
}

You can easily rotate the images using opencv python-

def funcRotate(degree=0):
    degree = cv2.getTrackbarPos('degree','Frame')
    rotation_matrix = cv2.getRotationMatrix2D((width / 2, height / 2), degree, 1)
    rotated_image = cv2.warpAffine(original, rotation_matrix, (width, height))
    cv2.imshow('Rotate', rotated_image)

If you are thinking of creating a trackbar, then simply create a trackbar using cv2.createTrackbar() and the call the funcRotate()fucntion from your main script. Then you can easily rotate it to any degree you want. Full details about the implementation can be found here as well- Rotate images at any degree using Trackbars in opencv

You'd better consider using Message Queues instead of advised methods. I'm sure this will be better solution, although it requires a little more job than just sending a request.

it is better to use json after post your resuest like below

  var clien = new RestClient("https://smple.com/");
  var request = new RestRequest("index", Method.POST);
  request.AddHeader("Sign", signinstance);    
  request.AddJsonBody(JsonConvert.SerializeObject(yourclass));
  var response = client.Execute<YourReturnclassSample>(request);
  if (response.StatusCode == System.Net.HttpStatusCode.Created)
   {
       return Ok(response.Content);
   }

The simplest way to log to stdout:

import logging
import sys
logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)

You can use append or prepend

The .append() method inserts the specified content as the last child of each element in the jQuery collection (To insert it as the first child, use .prepend()).

$("#tagscloud span").append(second);
$("#tagscloud span").append(third);
$("#tagscloud span").prepend(first);

You can use the following CSS for your input field:

.center-block {
  display: block;
  margin-right: auto;
  margin-left: auto;
}

Then,update your input field as following:

<input class="center-block" type="button" value="Some Button">

As of SLF4J 1.6.0, in the presence of multiple parameters and if the last argument in a logging statement is an exception, then SLF4J will presume that the user wants the last argument to be treated as an exception and not a simple parameter. See also the relevant FAQ entry.

So, writing (in SLF4J version 1.7.x and later)

 logger.error("one two three: {} {} {}", "a", "b", 
              "c", new Exception("something went wrong"));

or writing (in SLF4J version 1.6.x)

 logger.error("one two three: {} {} {}", new Object[] {"a", "b", 
              "c", new Exception("something went wrong")});

will yield

one two three: a b c
java.lang.Exception: something went wrong
    at Example.main(Example.java:13)
    at java.lang.reflect.Method.invoke(Method.java:597)
    at ...

The exact output will depend on the underlying framework (e.g. logback, log4j, etc) as well on how the underlying framework is configured. However, if the last parameter is an exception it will be interpreted as such regardless of the underlying framework.

This is the way it worked for me, because with other methods the form was sent empty:

<form name="yourform" id="yourform" method="POST" action="yourpage.html">
    <input type=hidden name="data" value="yourdata">
    <input type="submit" id="send" name="send" value="Send">
</form>
<script>            
    document.addEventListener("DOMContentLoaded", function(event) {
            document.createElement('form').submit.call(document.getElementById('yourform'));
            });         
</script>

kk: (01-24) will look like 01, 02..24.

HH:(00-23) will look like 00, 01..23.

hh:(01-12 in AM/PM) will look like 01, 02..12.

so the last printout (working2) is a bit weird. It should say 12:00:00 (edit: if you were setting the working2 timezone and format, which (as kdagli pointed out) you are not)

You are mixing razor and aspx syntax,if your view engine is razor just do this:

<button class="btn btn-info" type="button" id="addressSearch"   
          onclick="location.href='@Url.Action("List", "Search")'">

s = "hel\nlo"
raws = '%r'%s #coversion to raw string
#print(raws) will print 'hel\nlo' with single quotes.
print(raws[1:-1]) # will print hel\nlo without single quotes.
#raws[1:-1] string slicing is performed

Oops, the sed command has to precede the tidy command of course:

echo "$htmlstr" | 
sed '/type="global"/d' |
tidy -q -c -wrap 0 -numeric -asxml -utf8 --merge-divs yes --merge-spans yes 2>/dev/null |
xmlstarlet sel -N x="http://www.w3.org/1999/xhtml" -T -t -m "//x:table" -v '@name' -n

These would help.

Make sure there is an namespace definition (xmlns) for the namespace your control belong to.

To expand on what Shimi has said, you should only be running your loop from 1 to the square root of n. Then to find the pair, do n / i, and this will cover the whole problem space.

As was also noted, this is a NP, or 'difficult' problem. Exhaustive search, the way you are doing it, is about as good as it gets for guaranteed answers. This fact is used by encryption algorithms and the like to help secure them. If someone were to solve this problem, most if not all of our current 'secure' communication would be rendered insecure.

Python code:

import math

def divisorGenerator(n):
    large_divisors = []
    for i in xrange(1, int(math.sqrt(n) + 1)):
        if n % i == 0:
            yield i
            if i*i != n:
                large_divisors.append(n / i)
    for divisor in reversed(large_divisors):
        yield divisor

print list(divisorGenerator(100))

Which should output a list like:

[1, 2, 4, 5, 10, 20, 25, 50, 100]

I was heard that, one of the reasons is , the project is too large, so increasing the post buffer could solve the problem. so open the editSystemWideGitConfig, and add the following statements under [http] , postBuffer = 524288000. maybe work.

Just assuming you want to get the i-th least significant digit from an integer number x, you can try:

(abs(x)%(10**i))/(10**(i-1))

I hope it helps.

Quite late to this party, today I had the same problem. The right answer on macOs I think is use jenv

brew install jenv openjdk@11
jenv add /usr/local/opt/openjdk@11

And then add into Intellij IDEA as new SDK the following path:

~/.jenv/versions/11/libexec/openjdk.jdk/Contents/Home/

'1.0-0' will give you zero decimal places i.e. no decimals. e.g.$500

1.) Create an arraylist of appropriate type, in this case i.e String

2.) Create a JSONObject while passing your string to JSONObject constructor as input

• As JSONObject notation is represented by braces i.e {}
• Where as JSONArray notation is represented by square brackets i.e []

3.) Retrieve JSONArray from JSONObject (created at 2nd step) using "interests" as index.

4.) Traverse JASONArray using loops upto the length of array provided by length() function

5.) Retrieve your JSONObjects from JSONArray using getJSONObject(index) function

6.) Fetch the data from JSONObject using index '"interestKey"'.

Note : JSON parsing uses the escape sequence for special nested characters if the json response (usually from other JSON response APIs) contains quotes (") like this

`"{"key":"value"}"`

should be like this

`"{\"key\":\"value\"}"`

so you can use JSONParser to achieve escaped sequence format for safety as

JSONParser parser = new JSONParser();
JSONObject json = (JSONObject) parser.parse(inputString);

Code :

JSONParser parser = new JSONParser();
String response = "{interests : [{interestKey:Dogs}, {interestKey:Cats}]}";

JSONObject jsonObj = (JSONObject) parser.parse(response);

or

JSONObject jsonObj = new JSONObject("{interests : [{interestKey:Dogs}, {interestKey:Cats}]}");

List<String> interestList = new ArrayList<String>();

JSONArray jsonArray = jsonObj.getJSONArray("interests");

for(int i = 0 ; i < jsonArray.length() ; i++){
    interestList.add(jsonArray.getJSONObject(i).optString("interestKey"));
}

Note : Sometime you may see some exceptions when the values are not available in appropriate type or is there is no mapping key so in those cases when you are not sure about the presence of value so use optString, optInt, optBoolean etc which will simply return the default value if it is not present and even try to convert value to int if it is of string type and vice-versa so Simply No null or NumberFormat exceptions at all in case of missing key or value

From docs

Get an optional string associated with a key. It returns the defaultValue if there is no such key.

 public String optString(String key, String defaultValue) {

  String missingKeyValue = json_data.optString("status","N/A");
  // note there is no such key as "status" in response
  // will return "N/A" if no key found 

or To get empty string i.e "" if no key found then simply use

  String missingKeyValue = json_data.optString("status");
  // will return "" if no key found where "" is an empty string

• How to convert String to JSONObject in Java
• Convert one array list item into multiple Items

If by "empty" you mean undefined, it is the way ng-expressions are interpreted. Then, you could use :

<a ng-if="!item.photo" href="#/details/{{item.id}}"><img src="/img.jpg" class="img-responsive"></a>

I disagree that .form-group should be within .col-*-n elements. In my experience, all the appropriate padding happens automatically when you use .form-group like .row within a form.

<div class="form-group">
    <div class="col-sm-12">
        <label for="user_login">Username</label>
        <input class="form-control" id="user_login" name="user[login]" required="true" size="30" type="text" />
    </div>
</div>

Check out this demo.

Altering the demo slightly by adding .form-horizontal to the form tag changes some of that padding.

<form action="#" method="post" class="form-horizontal">

Check out this demo.

When in doubt, inspect in Chrome or use Firebug in Firefox to figure out things like padding and margins. Using .row within the form fails in edsioufi's fiddle because .row uses negative left and right margins thereby drawing the horizontal bounds of the divs classed .row beyond the bounds of the containing fieldsets.

You can use the https://graph.facebook.com/v3.0/{Place_your_Page_ID here}/feed?fields=id,shares,share_count&access_token={Place_your_access_token_here} to get the shares count.

The method System.Web.UI.Page.RegisterClientScriptBlock has been deprecated for some time (along with the other Page.Register* methods), ever since .NET 2.0 as shown by MSDN.

Instead use the .NET 2.0 Page.ClientScript.Register* methods. - (The ClientScript property expresses an instance of the ClientScriptManager class )

Guessing the problem

If you are saying your JavaScript alert box occurs before the page's content is visibly rendered, and therefore the page remains white (or still unrendered) when the alert box is dismissed by the user, then try using the Page.ClientScript.RegisterStartupScript(..) method instead because it runs the given client-side code when the page finishes loading - and its arguments are similar to what you're using already.

Also check for general JavaScript errors in the page - this is often seen by an error icon in the browser's status bar. Sometimes a JavaScript error will hold up or disturb unrelated elements on the page.

The CSS property display: inline-block was designed to address this need. You can read a bit about it here: http://robertnyman.com/2010/02/24/css-display-inline-block-why-it-rocks-and-why-it-sucks/

Below is an example of its use. The key elements are that the row element has white-space: nowrap and the cell elements have display: inline-block. This example should work on most major browsers; a compatibility table is available here: http://caniuse.com/#feat=inline-block

<html>
<body>
<style>

.row {
    float:left;
    border: 1px solid yellow;
    width: 100%;
    overflow: auto;
    white-space: nowrap;
}

.cell {
    display: inline-block;
    border: 1px solid red;
    width: 200px;
    height: 100px;
}
</style>

<div class="row">
    <div class="cell">a</div>
    <div class="cell">b</div>
    <div class="cell">c</div>
</div>

Message queues are ideal for requests which may take a long time to process. Requests are queued and can be processed offline without blocking the client. If the client needs to be notified of completion, you can provide a way for the client to periodically check the status of the request.

Message queues also allow you to scale better across time. It improves your ability to handle bursts of heavy activity, because the actual processing can be distributed across time.

Note that message queues and web services are orthogonal concepts, i.e. they are not mutually exclusive. E.g. you can have a XML based web service which acts as an interface to a message queue. I think the distinction your looking for is Message Queues versus Request/Response, the latter is when the request is processed synchronously.

I think this is a bit of a dodge to your question, but why not fork them into processes? My understanding of networking (from the hazy days of yore, I don't really code networks at all) was that each incoming connection can be handled as a separate process, because then if someone does something nasty in your process, it doesn't nuke the entire program.

This is an old question but there is some newer guidance in PEP 565 that to turn off all warnings if you're writing a python application you should use:

import sys
import warnings

if not sys.warnoptions:
    warnings.simplefilter("ignore")

The reason this is recommended is that it turns off all warnings by default but crucially allows them to be switched back on via python -W on the command line or PYTHONWARNINGS.

If you made any changes to packages -- reopen the sln. This worked for me!

You define the dependent module inside the setup.py of your own package with the "install_requires" option.

If your package needs to have some console script generated then you can use the "console_scripts" entry point in order to generate a wrapper script that will be placed within the 'bin' folder (e.g. of your virtualenv environment).

See an example below (this example uses the native JSON object). My changes are commented in CAPITALS:

function Foo(obj) // CONSTRUCTOR CAN BE OVERLOADED WITH AN OBJECT
{
    this.a = 3;
    this.b = 2;
    this.test = function() {return this.a*this.b;};

    // IF AN OBJECT WAS PASSED THEN INITIALISE PROPERTIES FROM THAT OBJECT
    for (var prop in obj) this[prop] = obj[prop];
}

var fooObj = new Foo();
alert(fooObj.test() ); //Prints 6

// INITIALISE A NEW FOO AND PASS THE PARSED JSON OBJECT TO IT
var fooJSON = new Foo(JSON.parse('{"a":4,"b":3}'));

alert(fooJSON.test() ); //Prints 12

Below is my initial code:

@echo off
Set z=%%
echo.
echo %z%0.......%0
echo %z%~0......%~0
echo %z%n0......%n0
echo %z%x0......%x0
echo %z%~n0.....%~n0
echo %z%dp0.....%dp0
echo %z%~dp0....%~dp0
echo.

I noticed that file name given by %~0 and %0 is the way it was entered in the command-shell and not how that file is actually named. So if you want the literal case used for the file name you should use %~n0. However, this will leave out the file extension. But if you know the file name you could add the following code.

set b=%~0
echo %~n0%b:~8,4%

I have learned that ":~8,4%" means start at the 9th character of the variable and then show show the next 4 characters. The range is 0 to the end of the variable string. So %Path% would be very long!

fIlEnAmE.bat
012345678901

However, this is not as sound as Jool's solution (%~x0) above.

My Evidence:

C:\bin>filename.bat

%0.......filename.bat
%~0......filename.bat
. . .

C:\bin>fIlEnAmE.bat

%0.......fIlEnAmE.bat
%~0......fIlEnAmE.bat
%n0......n0
%x0......x0
%~n0.....FileName
%dp0.....dp0
%~dp0....C:\bin\

%~n0%b:~8,4%...FileName.bat

Press any key to continue . . .

C:\bin>dir
 Volume in drive C has no label.
 Volume Serial Number is CE18-5BD0

 Directory of C:\bin
. . .
05/02/2018  11:22 PM               208 FileName.bat

Here is the final code

@echo off
Set z=%%
set b=%~0
echo.
echo %z%0.......%0
echo %z%~0......%~0
echo %z%n0......%n0
echo %z%x0......%x0
echo %z%~n0.....%~n0
echo %z%dp0.....%dp0

You should use UNION if you want to combine different resultsets. Try the following:

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id  
        WHERE products_id = 181) AS A)
UNION 

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id 
        WHERE products_id = 180) AS B
ON A.orders_id=B.orders_id)

Why don't you try using only this code:

dismiss();

If you want to dismiss the Dialog Fragment by its own. You can simply put this code inside the dialog fragment where you want to dismiss the Dialog.

For example:

button.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
       dismiss();
   }
});

This will close the recent Dialog Fragment that is shown on the screen.

Hope it helps for you.

so do the following edit my.cnf:

For me, only setting CUDA_VISIBLE_DEVICES to precisely -1 works:

Works:

import os
import tensorflow as tf

os.environ['CUDA_VISIBLE_DEVICES'] = '-1'

if tf.test.gpu_device_name():
    print('GPU found')
else:
    print("No GPU found")

# No GPU found

Does not work:

import os
import tensorflow as tf

os.environ['CUDA_VISIBLE_DEVICES'] = ''    

if tf.test.gpu_device_name():
    print('GPU found')
else:
    print("No GPU found")

# GPU found

If you want to add the row to the end of the grid use the Add() method of the Rows collection...

DataGridView1.Rows.Add(New String(){Value1, Value2, Value3})

If you want to insert the row at a partiular position use the Insert() method of the Rows collection (as GWLlosa also said)...

DataGridView1.Rows.Insert(rowPosition, New String(){value1, value2, value3})

I know you mentioned you weren't doing databinding, but if you defined a strongly-typed dataset with a single datatable in your project, you could use that and get some nice strongly typed methods to do this stuff rather than rely on the grid methods...

DataSet1.DataTable.AddRow(1, "John Doe", true)

There are a couple of simple one-liners you can use to do this.

1) Set a "style" attribute on the element:

element.setAttribute('style', 'display:inline !important');

or...

2) Modify the cssText property of the style object:

element.style.cssText = 'display:inline !important';

Either will do the job.

===

BTW - if you want a useful tool to manipulate !important rules in elements, I've written a jQuery plugin called "important": http://github.com/premasagar/important

I know that I'm not answering the xargs question directly but it's worth mentioning find's -exec option.

Given the following file system:

[root@localhost bokeh]# tree --charset assci bands
bands
|-- Dream\ Theater
|-- King's\ X
|-- Megadeth
`-- Rush

0 directories, 4 files

The find command can be made to handle the space in Dream Theater and King's X. So, to find the drummers of each band using grep:

[root@localhost]# find bands/ -type f -exec grep Drums {} +
bands/Dream Theater:Drums:Mike Mangini
bands/Rush:Drums: Neil Peart
bands/King's X:Drums:Jerry Gaskill
bands/Megadeth:Drums:Dirk Verbeuren

In the -exec option {} stands for the filename including path. Note that you don't have to escape it or put it in quotes.

The difference between -exec's terminators (+ and \;) is that + groups as many file names that it can onto one command line. Whereas \; will execute the command for each file name.

So, find bands/ -type f -exec grep Drums {} + will result in:

grep Drums "bands/Dream Theater" "bands/Rush" "bands/King's X" "bands/Megadeth"

and find bands/ -type f -exec grep Drums {} \; will result in:

grep Drums "bands/Dream Theater"
grep Drums "bands/Rush"
grep Drums "bands/King's X"
grep Drums "bands/Megadeth"

In the case of grep this has the side effect of either printing the filename or not.

[root@localhost bokeh]# find bands/ -type f -exec grep Drums {} \;
Drums:Mike Mangini
Drums: Neil Peart
Drums:Jerry Gaskill
Drums:Dirk Verbeuren

[root@localhost bokeh]# find bands/ -type f -exec grep Drums {} +
bands/Dream Theater:Drums:Mike Mangini
bands/Rush:Drums: Neil Peart
bands/King's X:Drums:Jerry Gaskill
bands/Megadeth:Drums:Dirk Verbeuren

Of course, grep's options -h and -H will control whether or not the filename is printed regardless of how grep is called.

xargs

xargs can also control how man files are on the command line.

xargs by default groups all the arguments onto one line. In order to do the same thing that -exec \; does use xargs -l. Note that the -t option tells xargs to print the command before executing it.

[root@localhost bokeh]# find ./bands -type f  | xargs -d '\n' -l -t grep Drums
grep Drums ./bands/Dream Theater 
Drums:Mike Mangini
grep Drums ./bands/Rush 
Drums: Neil Peart
grep Drums ./bands/King's X 
Drums:Jerry Gaskill
grep Drums ./bands/Megadeth 
Drums:Dirk Verbeuren

See that the -l option tells xargs to execute grep for every filename.

Versus the default (i.e. no -l option):

[root@localhost bokeh]# find ./bands -type f  | xargs -d '\n'  -t grep Drums
grep Drums ./bands/Dream Theater ./bands/Rush ./bands/King's X ./bands/Megadeth 
./bands/Dream Theater:Drums:Mike Mangini
./bands/Rush:Drums: Neil Peart
./bands/King's X:Drums:Jerry Gaskill
./bands/Megadeth:Drums:Dirk Verbeuren

xargs has better control on how many files can be on the command line. Give the -l option the max number of files per command.

[root@localhost bokeh]# find ./bands -type f  | xargs -d '\n'  -l2 -t grep Drums
grep Drums ./bands/Dream Theater ./bands/Rush 
./bands/Dream Theater:Drums:Mike Mangini
./bands/Rush:Drums: Neil Peart
grep Drums ./bands/King's X ./bands/Megadeth 
./bands/King's X:Drums:Jerry Gaskill
./bands/Megadeth:Drums:Dirk Verbeuren
[root@localhost bokeh]# 

See that grep was executed with two filenames because of -l2.

I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:

gcc -o exec main.o add.o

But my program is a C++ program. Using the g++ compiler solved my issue:

g++ -o exec main.o add.o

I was always under the impression that gcc could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.
