I saying that the case statement is wrong but this can be a good solution instead.
If you choose to use the CASE
statement, you have to make sure that at least one of the CASE
condition is matched. Otherwise, you need to define an error handler to catch the error. Recall that you don’t have to do this with the IF
statement.
SELECT if(hide = 0,FALSE,TRUE) col FROM tbl; #for BOOLEAN Value return
or
SELECT if(hide = 0,'FALSE','TRUE') col FROM tbl; #for string Value return
If you need the functionality if a index for a column exists (here at first place in sequence) as a database function you can use/adopt this code. If you want to check if an index exists at all regardless of the position in a multi-column-index, then just delete the part "AND SEQ_IN_INDEX = 1".

If this is really bothering you, why not write your own method isBetween(orderBean.getFiles().size(),0,5)
?
Another option is to use isEmpty
as it is a tad clearer:
if(!orderBean.getFiles().isEmpty() && orderBean.getFiles().size() < 5)
Also make sure /bin/bash is the proper location for bash .... if you took that line from an example somewhere it may not match your particular server. If you are specifying an invalid location for bash you're going to have a problem.
For the current date and time with format, Use
In Java
Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String strDate = sdf.format(c.getTime());
Log.d("Date","DATE : " + strDate)
In Kotlin
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val current = LocalDateTime.now()
val formatter = DateTimeFormatter.ofPattern("dd.MM.yyyy. HH:mm:ss")
var myDate: String = current.format(formatter)
Log.d("Date","DATE : " + myDate)
} else {
var date = Date()
val formatter = SimpleDateFormat("MMM dd yyyy HH:mma")
val myDate: String = formatter.format(date)
Log.d("Date","DATE : " + myDate)
}

This will give you the deadline :
select id,
title,
created_at + interval '1' day * claim_window as deadline
from projects
Alternatively the function make_interval
can be used:
select id,
title,
created_at + make_interval(days => claim_window) as deadline
from projects
To get all projects where the deadline is over, use:
select *
from (
select id,
created_at + interval '1' day * claim_window as deadline
from projects
) t
where localtimestamp at time zone 'UTC' > deadline
Use negative lookahead:
^(?!.*ab).*$
UPDATE: In the comments below, I stated that this approach is slower than the one given in Peter's answer. I've run some tests since then, and found that it's really slightly faster. However, the reason to prefer this technique over the other is not speed, but simplicity.
The other technique, described here as a tempered greedy token, is suitable for more complex problems, like matching delimited text where the delimiters consist of multiple characters (like HTML, as Luke commented below). For the problem described in the question, it's overkill.
For anyone who's interested, I tested with a large chunk of Lorem Ipsum text, counting the number of lines that don't contain the word "quo". These are the regexes I used:
(?m)^(?!.*\bquo\b).+$
(?m)^(?:(?!\bquo\b).)+$
Whether I search for matches in the whole text, or break it up into lines and match them individually, the anchored lookahead consistently outperforms the floating one.
When you're exporting to HTML, using <br>
works. However, if you're using pandoc to export to LaTeX/PDF as well, you should use grid tables:
+---------------+---------------+--------------------+
| Fruit | Price | Advantages |
+===============+===============+====================+
| Bananas | first line\ | first line\ |
| | next line | next line |
+---------------+---------------+--------------------+
| Bananas | first line\ | first line\ |
| | next line | next line |
+---------------+---------------+--------------------+
<Image Source="MyRessourceDir\images\addButton.png"/>
Remove the z-index value.
I would also recommend this approach.
HTML:
<header class="main-header" role="banner">
<img src="mybannerimage.gif" alt="Banner Image"/>
</header>
CSS:
.main-header {
text-align: center;
}
This will center your image with out stretching it out. You can adjust the padding as needed to give it some space around your image. Since this is at the top of your page you don't need to force it there with position absolute unless you want your other elements to go underneath it. In that case you'd probably want position:fixed; anyway.
true, this option is not available in any version of MS ppt.Now the solution is that You put your different sized slide in other file and put a hyperlink in first file.
You can use json.loads
:
import json
import requests
response = requests.get(...)
json_data = json.loads(response.text)
This converts a given string into a dictionary which allows you to access your JSON data easily within your code.
Or you can use @Martijn's helpful suggestion, and the higher voted answer, response.json()
.
I was asking the same to myself, and I found the answer in 1:
Take a look at section 8.1.7: the format "%z" (lowercase, the Z uppercase returns also the time zone, but not in the 4-digit format, but in the form of timezone abbreviations, like in [3]) of strftime returns the form "+/- 4DIGIT" that is standard in email headers (see section 3.3 of RFC 2822, see [2], which obsoletes the other ways of specifying the timezone for email headers).
So, if you want your timezone in this format, use:
time.strftime("%z")
[1] http://docs.python.org/2/library/datetime.html
[2] http://tools.ietf.org/html/rfc2822#section-3.3
[3] Timezone abbreviations: http://en.wikipedia.org/wiki/List_of_time_zone_abbreviations , only for reference.
You can use.`
Model.update({
'type': "newuser"
}, {
$set: {
email: "[email protected]",
phoneNumber:"0123456789"
}
}, {
multi: true
},
function(err, result) {
console.log(result);
console.log(err);
}) `
If the two ranges to be tested (your given cell and your given range) are not in the same Worksheet
, then Application.Intersect
throws an error. Thus, a way to avoid it is with something like
Sub test_inters(rng1 As Range, rng2 As Range)
If (rng1.Parent.Name = rng2.Parent.Name) Then
Dim ints As Range
Set ints = Application.Intersect(rng1, rng2)
If (Not (ints Is Nothing)) Then
' Do your job
End If
End If
End Sub
try {
// THIS for POST+JSON
options.contentType = 'application/json';
options.type = 'POST';
options.data = JSON.stringify(options.data);
// OR THIS for GET+URL-encoded
//options.data = $.param(_.clone(options.data));
console.log('.fetch options = ', options);
collection.fetch(options);
} catch (excp) {
alert(excp);
}
Just pieced this together for the same problem:
before_filter :validate_params
private
def validate_params
return head :bad_request unless params_present?
end
def params_present?
Set.new(%w(one two three)) <= (Set.new(params.keys)) &&
params.values.all?
end
the first line checks if our target keys are present in the params' keys using the <= subset? operator. Enumerable.all? without block per default returns false if any value is nil or false.
There's no such thing as a “good hash function” for universal hashes (ed. yes, I know there's such a thing as “universal hashing” but that's not what I meant). Depending on the context different criteria determine the quality of a hash. Two people already mentioned SHA. This is a cryptographic hash and it isn't at all good for hash tables which you probably mean.
Hash tables have very different requirements. But still, finding a good hash function universally is hard because different data types expose different information that can be hashed. As a rule of thumb it is good to consider all information a type holds equally. This is not always easy or even possible. For reasons of statistics (and hence collision), it is also important to generate a good spread over the problem space, i.e. all possible objects. This means that when hashing numbers between 100 and 1050 it's no good to let the most significant digit play a big part in the hash because for ~ 90% of the objects, this digit will be 0. It's far more important to let the last three digits determine the hash.
Similarly, when hashing strings it's important to consider all characters – except when it's known in advance that the first three characters of all strings will be the same; considering these then is a waste.
This is actually one of the cases where I advise to read what Knuth has to say in The Art of Computer Programming, vol. 3. Another good read is Julienne Walker's The Art of Hashing.
You've no doubt solved this by now or decided to do something different, but as it has not been answered & I stumbled across this when looking for something similar I thought I'd share my method.
I've taken to using two div sets. One has hidden-xs and is for sm, md & lg device viewing. The other has hidden-sm, -md, -lg and is only for mobile. Now I have a lot more control over the display in my CSS.
You can see a rough idea in this js fiddle where I set the footer and buttons to be smaller when the resolution is of the -xs size.
<div class="modal-footer">
<div class="hidden-xs">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
<div class="hidden-sm hidden-md hidden-lg sml-footer">
<button type="button" class="btn btn-xs btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-xs btn-primary">Save changes</button>
</div>
</div>
Explicitly using a Carrage Return (\r) at the beginning of the line rather than (implicitly or explicitly) using a New Line (\n) at the end should get what you want. For example:
void demoPercentDone() {
for(int i = 0; i < 100; i++) {
System.Console.Write( "\rProcessing {0}%...", i );
System.Threading.Thread.Sleep( 1000 );
}
System.Console.WriteLine();
}
Not sure why this isn't implemented directly in R, but this answer is essentially the same as Andrii's and Wordsforthewise, I just turned into a function for the sake of convenience if somebody uses it a lot like me.
r2_general <-function(preds,actual){
return(1- sum((preds - actual) ^ 2)/sum((actual - mean(actual))^2))
}
Here's another option:
df.replace(to_replace=[None], value=np.nan, inplace=True)
There is no such a thing as "first" item in a Collection
because it is .. well simply a collection.
From the Java doc's Collection.iterator() method:
There are no guarantees concerning the order in which the elements are returned...
So you can't.
If you use another interface such as List, you can do the following:
String first = strs.get(0);
But directly from a Collection this is not possible.
inputmode
according to WHATWG spec is the the default method.
For iOS devices adding pattern
could also help.
For backward compatibility use type
as well since Chrome use these as of version 66.
<input
inputmode="numeric"
pattern="[0-9]*"
type="number"
/>
To add interceptor to a spring boot application, do the following
Create an interceptor class
public class MyCustomInterceptor implements HandlerInterceptor{
//unimplemented methods comes here. Define the following method so that it
//will handle the request before it is passed to the controller.
@Override
public boolean preHandle(HttpServletRequest request,HttpServletResponse response){
//your custom logic here.
return true;
}
}
Define a configuration class
@Configuration
public class MyConfig extends WebMvcConfigurerAdapter{
@Override
public void addInterceptors(InterceptorRegistry registry){
registry.addInterceptor(new MyCustomInterceptor()).addPathPatterns("/**");
}
}
Thats it. Now all your requests will pass through the logic defined under preHandle() method of MyCustomInterceptor.
I stumbled over the same question and I've found a solution.
First make sure you upgrade to LESS 1.6 at least.
You can use npm
for that case.
Now you can use the following mixin:
.if (@condition, @property, @value) when (@condition = true){
@{property}: @value;
}
Since LESS 1.6 you are able to pass PropertyNames to Mixins as well. So for example you could just use:
.myHeadline {
.if(@include-lineHeight, line-height, '35px');
}
If @include-lineheight resolves to true LESS will print the line-height: 35px
and it will skip the mixin if @include-lineheight is not true.
I use this function in my python programs. The input for the function is as example:
value = time.time()
def stopWatch(value):
'''From seconds to Days;Hours:Minutes;Seconds'''
valueD = (((value/365)/24)/60)
Days = int (valueD)
valueH = (valueD-Days)*365
Hours = int(valueH)
valueM = (valueH - Hours)*24
Minutes = int(valueM)
valueS = (valueM - Minutes)*60
Seconds = int(valueS)
print Days,";",Hours,":",Minutes,";",Seconds
start = time.time() # What in other posts is described is
***your code HERE***
end = time.time()
stopWatch(end-start) #Use then my code
The best way is to insert an appropriate input tag:
<input type="submit" value="submit" />
<form id="form-id">
<button id="your-id">submit</button>
</form>
var form = document.getElementById("form-id");
document.getElementById("your-id").addEventListener("click", function () {
form.submit();
});
Enclose the latter JavaScript code by an DOMContentLoaded
event (choose only load
for backward compatiblity) if you haven't already done so:
window.addEventListener("DOMContentLoaded", function () {
var form = document.... // copy the last code block!
});
Add an onclick
attribute to the link and an id
to the form:
<form id="form-id">
<a href="#" onclick="document.getElementById('form-id').submit();"> submit </a>
</form>
Whatever way you choose, you have call formObject.submit()
eventually (where formObject
is the DOM object of the <form>
tag).
You also have to bind such an event handler, which calls formObject.submit()
, so it gets called when the user clicked a specific link or button. There are two ways:
Recommended: Bind an event listener to the DOM object.
// 1. Acquire a reference to our <form>.
// This can also be done by setting <form name="blub">:
// var form = document.forms.blub;
var form = document.getElementById("form-id");
// 2. Get a reference to our preferred element (link/button, see below) and
// add an event listener for the "click" event.
document.getElementById("your-id").addEventListener("click", function () {
form.submit();
});
Not recommended: Insert inline JavaScript. There are several reasons why this technique is not recommendable. One major argument is that you mix markup (HTML) with scripts (JS). The code becomes unorganized and rather unmaintainable.
<a href="#" onclick="document.getElementById('form-id').submit();">submit</a>
<button onclick="document.getElementById('form-id').submit();">submit</button>
Now, we come to the point at which you have to decide for the UI element which triggers the submit() call.
A button
<button>submit</button>
A link
<a href="#">submit</a>
Apply the aforementioned techniques in order to add an event listener.
Try replacing the string literal for date '1989-12-09'

So use : column_old_value='None'
Just to extend the @Joseph's answer:

There could be two ways/syntax to bind a static
property. If p is a static
property in class MainWindow
, then binding
for textbox
will be:
1.
<TextBox Text="{x:Static local:MainWindow.p}" />
2.
<TextBox Text="{Binding Source={x:Static local:MainWindow.p},Mode=OneTime}" />
Apache's errorlog will explain why you get a permission denied. Also, serverfault.com is a better forum for a question like this.
If the error log simply says "permission denied", su to the user that the webserver is running as and try to read from the file in question. So for example:
sudo -s
su - nobody
cd /
cd /home
cd user
cd xxx
cat index.html
See if one of those gives you the "permission denied" error.
Precision, Scale, and Length in the SQL Server 2000 documentation reads:
Precision is the number of digits in a number. Scale is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a precision of 5 and a scale of 2.
NEQ is usually used for numbers and == is typically used for string comparison.
I cannot find any documentation that mentions a specific and equivalent inequality operand for string comparison (in place of NEQ). The solution using IF NOT == seems the most sound approach. I can't immediately think of a circumstance in which the evaluation of operations in a batch file would cause an issue or unexpected behavior when applying the IF NOT == comparison method to strings.
I wish I could offer insight into how the two functions behave differently on a lower level - would disassembling separate batch files (that use NEQ and IF NOT ==) offer any clues in terms of which (unofficially documented) native API calls conhost.exe is utilizing?
As the title suggests that we want to adjust the size of the labels and not the tick marks I figured that I actually might add something to the question, you need to use the mtext() if you want to specify one of the label sizes, or you can just use par(cex.lab=2)
as a simple alternative. Here's a more advanced mtext() example:
set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data=foo,
yaxt="n", ylab="",
xlab="Regular boring x",
pch=16,
col="darkblue")
axis(2,cex.axis=1.2)
mtext("Awesome Y variable", side=2, line=2.2, cex=2)
You may need to adjust the line=
option to get the optimal positioning of the text but apart from that it's really easy to use.
A functional approach in order to get digits from a number
would be to get a string
from your number
, split it into an array
(of characters) and map each element back into a number.
For example:
var number = 123456;
var array = number.toString()
.split('')
.map(function(item, index) {
return parseInt(item);
});
console.log(array); // returns [1, 2, 3, 4, 5, 6]
If you also need to sum all digits, you can append the reduce()
method to the previous code:
var num = 123456;
var array = num.toString()
.split('')
.map(function(item, index) {
return parseInt(item);
})
.reduce(function(previousValue, currentValue, index, array) {
return previousValue + currentValue;
}, 0);
console.log(array); // returns 21
As an alternative, with ECMAScript 2015 (6th Edition), you can use arrow functions:
var number = 123456;
var array = number.toString().split('').map((item, index) => parseInt(item));
console.log(array); // returns [1, 2, 3, 4, 5, 6]
If you need to sum all digits, you can append the reduce()
method to the previous code:
var num = 123456;
var result = num.toString()
.split('')
.map((item, index) => parseInt(item))
.reduce((previousValue, currentValue) => previousValue + currentValue, 0);
console.log(result); // returns 21

Note that COLUMNS
is:
SIGWINCH
signal.That second point usually means that your COLUMNS
variable will only be set in your interactive shell, not in a bash script.
If your script's stdin
is connected to your terminal you can manually look up the width of your terminal by asking your terminal:
tput cols
And to use this in your SVN command:
svn diff "$@" --diff-cmd /usr/bin/diff -x "-y -w -p -W $(tput cols)"
(Note: you should quote "$@"
and stay away from eval
;-))
The simplest way to do this without needing to create anything extra would be to just modify the simple list TextView
:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, strings) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView textView = (TextView) super.getView(position, convertView, parent);
textView.setTextColor({YourColorHere});
return textView;
}
};
One thing that wasn't mentioned completely (although @BlooB kinda mentioned it) is that map returns a map object NOT a list. This is a big difference when it comes to time performance on initialization and iteration. Consider these two tests.
import time
def test1(iterable):
a = time.clock()
map(str, iterable)
a = time.clock() - a
b = time.clock()
[ str(x) for x in iterable ]
b = time.clock() - b
print(a,b)
def test2(iterable):
a = time.clock()
[ x for x in map(str, iterable)]
a = time.clock() - a
b = time.clock()
[ str(x) for x in iterable ]
b = time.clock() - b
print(a,b)
test1(range(2000000)) # Prints ~1.7e-5s ~8s
test2(range(2000000)) # Prints ~9s ~8s
As you can see initializing the map function takes almost no time at all. However iterating through the map object takes longer than simply iterating through the iterable. This means that the function passed to map() is not applied to each element until the element is reached in the iteration. If you want a list use list comprehension. If you plan to iterate through in a for loop and will break at some point, then use map.
Please take a look here:
1) You can use this with Windows (incl. MinGW) as well as Linux. Alternative you can only use the code as an example.
2) Step-by-step tutorial how to use serial ports on windows
3) You can use this literally on MinGW
Here's some very, very simple code (without any error handling or settings):
#include <windows.h>
/* ... */
// Open serial port
HANDLE serialHandle;
serialHandle = CreateFile("\\\\.\\COM1", GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0);
// Do some basic settings
DCB serialParams = { 0 };
serialParams.DCBlength = sizeof(serialParams);
GetCommState(serialHandle, &serialParams);
serialParams.BaudRate = baudrate;
serialParams.ByteSize = byteSize;
serialParams.StopBits = stopBits;
serialParams.Parity = parity;
SetCommState(serialHandle, &serialParams);
// Set timeouts
COMMTIMEOUTS timeout = { 0 };
timeout.ReadIntervalTimeout = 50;
timeout.ReadTotalTimeoutConstant = 50;
timeout.ReadTotalTimeoutMultiplier = 50;
timeout.WriteTotalTimeoutConstant = 50;
timeout.WriteTotalTimeoutMultiplier = 10;
SetCommTimeouts(serialHandle, &timeout);
Now you can use WriteFile()
/ ReadFile()
to write / read bytes.
Don't forget to close your connection:
CloseHandle(serialHandle);
As @Donal Fellows wrote, you have to query the network interface instead of the machine. This code from the javadocs worked for me:
The following example program lists all the network interfaces and their addresses on a machine:
import java.io.*;
import java.net.*;
import java.util.*;
import static java.lang.System.out;
public class ListNets {
public static void main(String args[]) throws SocketException {
Enumeration<NetworkInterface> nets = NetworkInterface.getNetworkInterfaces();
for (NetworkInterface netint : Collections.list(nets))

You must call cfmakeraw
on a tty
obtained from tcgetattr
. You cannot zero-out a struct termios
, configure it, and then set the tty
with tcsetattr
. If you use the zero-out method, then you will experience unexplained intermittent failures, especially on the BSDs and OS X. "Unexplained intermittent failures" include hanging in read(3)

(meaning no parity), PARENB|PARODD
(enable parity and use odd), PARENB
(enable parity and use even), PARENB|PARODD|CMSPAR
(mark parity), and PARENB|CMSPAR
(space parity).
"Blocking" sets whether a read()
on the port waits for the specified number of characters to arrive. Setting no blocking means that a read()
returns however many characters are available without waiting for more, up to the buffer limit.
Addendum:
CMSPAR
is needed only for choosing mark and space parity, which is uncommon. For most applications, it can be omitted. My header file /usr/include/bits/termios.h
enables definition of CMSPAR
only if the preprocessor symbol __USE_MISC
is defined. That definition occurs (in features.h
) with
#if defined _BSD_SOURCE || defined _SVID_SOURCE
#define __USE_MISC 1
#endif
The introductory comments of <features.h>
says:
/* These are defined by the user (or the compiler)
to specify the desired environment:
...
_BSD_SOURCE ISO C, POSIX, and 4.3BSD things.
_SVID_SOURCE ISO C, POSIX, and SVID things.

You can use fetch module to copy files from remote hosts to local, and lookup module to read the content of fetched files.
By using the ROW()
function I can drag this formula vertically. It can also be dragged horizontally since there is no $
before the D
.
= INDIRECT("'"&D$2&"'!$B"&ROW())
My layout has sheet names as column headers (B2
, C2
, D2
, etc.) and maps multiple row values from Column B
in each sheet.
This function will recursively put only files into a list.
import os
def ls_files(dir):
files = list()
for item in os.listdir(dir):
abspath = os.path.join(dir, item)
try:
if os.path.isdir(abspath):
files = files + ls_files(abspath)
else:
files.append(abspath)
except FileNotFoundError as err:
print('invalid directory\n', 'Error: ', err)
return files
This way worked for me:
adding the path that you like:
export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add
checking: you can run 'export' cmd and check the output or you can check it using this cmd:
python -c "import sys; print(sys.path)"
If you know the start and end index you may use this
string = string.substring(0, start_index) + string.substring(end_index, string.length());
Should a dictionary like:
{'red': '0.500', 'yellow': '0.250, 'blue': '0.125'}
be required out of a dataframe like:
a b
0 red 0.500
1 yellow 0.250
2 blue 0.125
simplest way would be to do:
dict(df.values)
working snippet below:
import pandas as pd
df = pd.DataFrame({'a': ['red', 'yellow', 'blue'], 'b': [0.5, 0.25, 0.125]})
dict(df.values)
It's good practice to give a parent to your QTimer
to use Qt's memory management system.
update()
is a QWidget function - is that what you are trying to call or not? http://qt-project.org/doc/qt-4.8/qwidget.html#update.
If number 2 does not apply, make sure that the function you are trying to trigger is declared as a slot in the header.
Finally if none of these are your issue, it would be helpful to know if you are getting any run-time connect errors.
Update: Genymotion's 2.5.1 release (https://www.genymotion.com/#!/release-notes/251#251) seems to have fixed this issue. (thanks for the heads up @Roger!)
For those that may be stumbling upon this a bit later, I resolved this by installing VirtualBox 4.3.28 (https://www.virtualbox.org/wiki/Download_Old_Builds_4_3). The new 5.0.0 and 4.3.30 versions didn't work for me with Genymotion 2.5. None of the above solutions worked :(
It's also worth noting that at the time of writing, Genymotion's FAQ states the following:
However, for performance reasons, we recommend using version 4.3.12
Try with below logic
driver.get("http://www.labmultis.info/jpecka.portal-exdrazby/index.php?c1=2&a=s&aa=&ta=1");
List<WebElement> allElements=driver.findElements(By.cssSelector(".list.list-categories li"));
for(WebElement ele :allElements) {
System.out.println("Name + Number===>"+ele.getText());
String s=ele.getText();
s=s.substring(s.indexOf("(")+1, s.indexOf(")"));
System.out.println("Number==>"+s);
}

Whevever you get a problem like this just go to the man page for the function in question and it will tell you what header you are missing, e.g.

LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>

memset(void *b, int c, size_t len);
Note that for C++ it's generally preferable to use the proper equivalent C++ headers, <cstring>
/<cstdio>
/<cstdlib>
/etc, rather than C's <string.h>

The problem described here was solved by me quite a long time ago but I don't really remember what was the main reason that uploads weren't working. There were multiple things that needed fixing so the upload could work. I have created checklist that might help others having similar problems and I will edit it to make it as helpful as possible. As I said before on chat, I was working on embedded system, so some points may be skipped on non-embedded systems.
Check upload_tmp_dir
in php.ini. This is directory where PHP stores temporary files while uploading.
Check open_basedir
in php.ini. If defined it limits PHP read/write rights to specified path and its subdirectories. Ensure that upload_tmp_dir
is inside this path.
Check post_max_size
in php.ini. If you want to upload 20 Mbyte files, try something a little bigger, like post_max_size = 21M
. This defines largest size of POST message which you are probably using during upload.
Check upload_max_filesize
in php.ini. This specifies biggest file that can be uploaded.
Check memory_limit
in php.ini. That's the maximum amount of memory a script may consume. It's quite obvious that it can't be lower than upload size (to be honest I'm not quite sure about it-PHP is probably buffering while copying temporary files).
Ensure that you're checking the right php.ini file that is one used by PHP on your webserver. The best solution is to execute script with directive described here http://php.net/manual/en/function.php-ini-loaded-file.php (php_ini_loaded_file
function)
Check what user php runs as (See here how to do it: How to check what user php is running as? ). I have worked on different distros and servers. Sometimes it is apache
, but sometimes it can be root
. Anyway, check that this user has rights for reading and writing in the temporary directory and directory that you're uploading into. Check all directories in the path in case you're uploading into subdirectory (for example /dir1/dir2/
-check both dir1
and dir2
.
On embedded platforms you sometimes need to restrict writing to root filesystem because it is stored on flash card and this helps to extend life of this card. If you are using scripts to enable/disable file writes, ensure that you enable writing before uploading.
I had serious problems with PHP >5.4 upload monitoring based on sessions (as described here http://phpmaster.com/tracking-upload-progress-with-php-and-javascript/ ) on some platforms. Try something simple at first (like here: http://www.dzone.com/snippets/very-simple-php-file-upload ). If it works, you can try more sophisticated mechanisms.
If you make any changes in php.ini remember to restart server so the configuration will be reloaded.
I solved this with the TFS powertools (dec 2011 - for VS 2010 TFS 2010)
http://visualstudiogallery.msdn.microsoft.com/c255a1e4-04ba-4f68-8f4e-cd473d6b971f
Find in Source Control | Status... allows you to find all files checked out to a specific person
right click and UNDO... can remove each checkout.
What you seem to want would allow for a static method to be called via both the Type or any instance of that type. This would at very least result in ambiguity which is not a desirable trait.
There would be endless debates about whether it mattered, which is best practice and whether there are performance issues doing it one way or another. By simply not supporting it C# saves us having to worry about it.
Its also likely that a compilier that conformed to this desire would lose some optimisations that may come with a more strict separation between instance and static methods.
For Symfony 3.4
Check the constant in this file vendor/symfony/http-kernel/Kernel.php
const VERSION = '3.4.3';
OR
composer show | grep symfony/http-kernel
You may obtain the stream key via the API: https://github.com/justintv/twitch-api
Wrap it in double quotes
alter user "dell-sys" with password 'Pass@133';
Notice that you will have to use the same case you used when you created the user using double quotes. Say you created "Dell-Sys"
then you will have to issue exact the same whenever you refer to that user.
I think the best you do is to drop that user and recreate without illegal identifier characters and without double quotes so you can later refer to it in any case you want.
getElementById
returns a single object for which you can specify the style.So, the above explanation is correct.
getElementsByTagName
returns multiple objects(array of objects and properties) for which we cannot apply the style directly.
You need to explicitly get the int value using method intValue() like this:
Double d = 5.25;
Integer i = d.intValue(); // i becomes 5
Or
double d = 5.25;
int i = (int) d;
You have to modify the control template instead of ItemsPanelTemplate:
<ItemsControl >
<ItemsControl.Template>
<ControlTemplate>
<ScrollViewer x:Name="ScrollViewer" Padding="{TemplateBinding Padding}">
<ItemsPresenter />
</ScrollViewer>
</ControlTemplate>
</ItemsControl.Template>
</ItemsControl>
Maybe, your code does not working because StackPanel has own scrolling functionality. Try to use StackPanel.CanVerticallyScroll property.
Use Datatable.Default.Sort
property and then bind it to the datagridview.
That's because you're using a non-blocking
socket and the output buffer is full.
From the send()
man page
When the message does not fit into the send buffer of the socket,
send() normally blocks, unless the socket has been placed in non-block-
ing I/O mode. In non-blocking mode it would return EAGAIN in this
case.
EAGAIN is the error code tied to "Resource temporarily unavailable"
Consider using select()
to get a better control of this behaviours
ProxyPass /node http://localhost:8000/
You put your template in the wrong place. From the Flask docs:
Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package: See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates
At a very high level:
Abstraction of any kind comes down to separating concerns. "Client" code of an abstraction doesn't care how the contract exposed by the abstraction is fulfilled. You usually don't care if a string class uses a null-terminated or buffer-length-tracked internal storage implementation, for example. Encapsulation hides the details, but by making classes/methods/etc. abstract, you allow the implementation to change or for new implementations to be added without affecting the client code.
I have modified the function of Mr.net_prog which gets only the picture box and rotate the image in it.
public static void RotateImage(PictureBox picBox)
{
Image img = picBox.Image;
var bmp = new Bitmap(img);
using (Graphics gfx = Graphics.FromImage(bmp))
{
gfx.Clear(Color.White);
gfx.DrawImage(img, 0, 0, img.Width, img.Height);
}
bmp.RotateFlip(RotateFlipType.Rotate270FlipNone);
picBox.Image = bmp;
}
When you do echo $array;
, PHP will simply echo 'Array' since it can't convert an array to a string. So The 'A' that you are actually getting is the first letter of Array, which is correct.
You might actually need
echo json_encode($array);
This should get you what you want.
EDIT : And obviously, you'd need to change your JS to work with JSON instead of just text (as pointed out by @genesis)
Use something like header( 'Location: /my-other-page.html' );
to redirect. You can't have sent any other data on the page before you do this though.
In case you don't want/need to post:
@Html.ActionLink("link caption", "actionName", new { Model.Page }) // view's controller
@Html.ActionLink("link caption", "actionName", "controllerName", new { reportID = 1 }, null);
[HttpGet]
public ActionResult actionName(int reportID)
{
Note that the reportID in the new {} part matches reportID in the action parameters, you can add any number of parameters this way, but any more than 2 or 3 (some will argue always) you should be passing a model via a POST (as per other answer)
Edit: Added null for correct overload as pointed out in comments. There's a number of overloads and if you specify both action+controller, then you need both routeValues and htmlAttributes. Without the controller (just caption+action), only routeValues are needed but may be best practice to always specify both.
The pull
command is:
adb pull source dest
When you write:
adb pull /data/data/path.to.package/databases/data /sdcard/test
It means that you'll pull from /data/data/path.to.package/databases/data
and you'll copy it to /sdcard/test
, but the destination MUST be a local directory. You may write C:\Users\YourName\temp
instead.
For example:
adb pull /data/data/path.to.package/databases/data c:\Users\YourName\temp
This worked for me and I think is more HTML5 compliant. You should change your html to use 'data-' prefix
<div data-example-directive data-number="99"></div>
And within the directive read the variable's value:
scope: {
number : "=",
....
},
I came across an amazing resource on css-tricks: https://css-tricks.com/using-svg/
There are a handful of solutions explained there.
I preferred the one that required minimal edits to the source svg, and also didn't require it to be embedded into the html document. This option utilizes the <object>
tag.
Add the svg file into your html using <object>
; I also declared html attributes width
and height
. Using these width and heights the svg document does not get scaled, I worked around that using a css transform: scale(...)
statement for the svg
tag in my associated svg css file.
<object type="image/svg+xml" data="myfile.svg" width="64" height="64"></object>
Create a css file to attach to your svn document. My source svg path was scaled to 16px, I upscaled it to 64 with a factor of four. It only had one path so I did not need to select it more specifically, however the path had a fill attribute so I had to use !IMPORTANT
to force the css to take precedent.
#svg2 {
width: 64px; height: 64px;
transform: scale(4);
}
path {
fill: #333 !IMPORTANT;
}
Edit your target svg file, before the opening <svg
tag, to include a stylesheet; Note that the href is relative to the svg file url.
<?xml-stylesheet type="text/css" href="myfile.css" ?>
Try this coding
<div>
<iframe id='iframe2' src="Mypage.aspx" frameborder="0" style="overflow: hidden; height: 100%;
width: 100%; position: absolute;"></iframe>
</div>
if (property_exists($ob, 'a'))
if (isset($ob->a))
isset() will return false if property is null
Example 1:
$ob->a = null
var_dump(isset($ob->a)); // false
Example 2:
class Foo
{
public $bar = null;
}
$foo = new Foo();
var_dump(property_exists($foo, 'bar')); // true
var_dump(isset($foo->bar)); // false
If you look at the first few lines of the implementation of java.util.HashSet
you will see:
public class HashSet<E>
....
private transient HashMap<E,Object> map;
So HashSet
uses HashMap
interally anyway, which means that if you just use a HashMap
directly and use the same value as the key and the value you will get the effect you want and save yourself some memory.
Currently, Robomongo 0.8.x doesn't work with MongoDB 3.0:
For now, don't use Robomongo. For me, the best solution is to use MongoChef.
It can be resolved as follows:
Go to Project properties.
Then 'Java Compiler' -> Check the box ('Enable project specific settings')
Change the compiler compliance level to '5.0' & click ok.
Do rebuild. It will be resolved.
Also, click the checkbox for "Use default compliance settings".
Just like some other answers, I recommend to use String.format()
and BigInteger
. But to interpret the byte array as big-endian binary representation instead of two's-complement binary representation (with signum and incomplete use of possible hex values range) use BigInteger(int signum, byte[] magnitude), not BigInteger(byte[] val).
For example, for a byte array of length 8 use:
String.format("%016X", new BigInteger(1,bytes))
Advantages:
Disadvantage:
Example:
byte[] bytes = new byte[8];
Random r = new Random();
System.out.println("big-endian | two's-complement");
System.out.println("-----------------|-----------------");
for (int i = 0; i < 10; i++) {
r.nextBytes(bytes);
System.out.print(String.format("%016X", new BigInteger(1,bytes)));
System.out.print(" | ");
System.out.print(String.format("%016X", new BigInteger(bytes)));
System.out.println();
}
Example output:
big-endian | two's-complement

When doing Flask Basic auth I got this error and then I realized I had wrapped_view(**kwargs) and it worked after changing it to wrapped_view(*args, **kwargs).
var data="your data";//ex data="id="+id;
$.ajax({
method : "POST",
url : "file name", //url: "demo.php"
data : "data",
success : function(result){
//set result to div or target
//ex $("#divid).html(result)

You may try the following if your database does not have any data OR you have another away to restore that data. You will need to know the Ubuntu server root password but not the mysql root password.
It is highly probably that many of us have installed "mysql_secure_installation" as this is a best practice. Navigate to bin directory where mysql_secure_installation exist. It can be found in the /bin directory on Ubuntu systems. By rerunning the installer, you will be prompted about whether to change root database password.
The magic happens when calling SaveChanges()
and depends on the current EntityState
. If the entity has an EntityState.Added
, it will be added to the database, if it has an EntityState.Modified
, it will be updated in the database. So you can implement an InsertOrUpdate()
method as follows:
public void InsertOrUpdate(Blog blog)
{
using (var context = new BloggingContext())
{
context.Entry(blog).State = blog.BlogId == 0 ?
EntityState.Added :
EntityState.Modified;
context.SaveChanges();
}
}
If you can't check on Id = 0
to determine if it's a new entity or not, check the answer of Ladislav Mrnka.
If your attachments are
@attachments = Job.find(1).attachments
This will be array of attachment objects
Use select method to filter based on file_type.
@logos = @attachments.select { |attachment| attachment.file_type == 'logo' }
@images = @attachments.select { |attachment| attachment.file_type == 'image' }
This will not trigger any db query.
The JDK 1.6 I'm currently using on OSX Mountain Lion did not come with a src.zip
either, and as far as i can tell there is no supported OSX JDK for 1.6 available anymore.
So I downloaded the OpenJDK source (using the links from the accepted answer (+1)) then ran:
cd ~/Downloads
mkdir jdk6src
cd jdk6src
tar xf ../openjdk-6-src-b27-26_oct_2012.tar.gz
cd jdk/src/share/classes
jar cf /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/src.jar *
(your file names and paths may vary...)
Associate that src.jar
with the appropriate Java platform in your IDE and you should be good to go.
There are some discrepancies between the OpenJDK source and the JDK I'm currently running (line numbers don't match up in the debugger, for one), but if all you want is a zip/jar to point your IDE to for the relatively few cases you need to peek at some code to understand how something works, then this should do the trick.
I had to play with the widths of my main containers:
html {
@media only screen and (orientation: portrait) and (max-width: 555px) {
transform: rotate(90deg);
width: calc(155%);
.content {
width: calc(155%);
}
}
}
Reduction : I think @John Feminella solution O(n2) is most elegant. We can still reduce the A[n] in which to search for tuple. By observing A[k] such that all elements would be in A[0] - A[k], when our search array is huge and SUM (s) really small.
A[0] is minimum :- Ascending sorted array.
s = 2A[0] + A[k] : Given s and A[] we can find A[k] using binary search in log(n) time.
I wrote a similar solution some time ago.
Of course it's just a PoC and can be improved further.

To substantiate @deceze's claim that the default JSON encoding is UTF-8...
From IETF RFC4627:
JSON text SHALL be encoded in Unicode. The default encoding is UTF-8.
Since the first two characters of a JSON text will always be ASCII characters [RFC0020], it is possible to determine whether an octet stream is UTF-8, UTF-16 (BE or LE), or UTF-32 (BE or LE) by looking at the pattern of nulls in the first four octets.
00 00 00 xx UTF-32BE 00 xx 00 xx UTF-16BE xx 00 00 00 UTF-32LE xx 00 xx 00 UTF-16LE xx xx xx xx UTF-8
First of all you missed ScriptService attribute to add in webservice.
[ScriptService]
After then try following method to call webservice via JSON.
var webAddr = "http://Domain/VBRService.asmx/callJson"; var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr); httpWebRequest.ContentType = "application/json; charset=utf-8"; httpWebRequest.Method = "POST"; using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) { string json = "{\"x\":\"true\"}"; streamWriter.Write(json); streamWriter.Flush(); } var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) { var result = streamReader.ReadToEnd(); return result; }

}
}
}

MyArrayList<String>myArrayList=new MyArrayList<String>("s1","s2","s2");
>>> import numpy

power(x1, x2[, out])
First array elements raised to powers from second array, element-wise.
Raise each base in `x1` to the positionally-corresponding power in
`x2`. `x1` and `x2` must be broadcastable to the same shape.
Parameters
----------
x1 : array_like
The bases.
x2 : array_like
The exponents.
Returns
-------
y : ndarray
The bases in `x1` raised to the exponents in `x2`.
Examples
--------
Cube each element in a list.
>>> x1 = range(6)
>>> x1
[0, 1, 2, 3, 4, 5]
>>> np.power(x1, 3)
array([ 0, 1, 8, 27, 64, 125])
Raise the bases to different exponents.
>>> x2 = [1.0, 2.0, 3.0, 3.0, 2.0, 1.0]
>>> np.power(x1, x2)
array([ 0., 1., 8., 27., 16., 5.])
The effect of broadcasting.
>>> x2 = np.array([[1, 2, 3, 3, 2, 1], [1, 2, 3, 3, 2, 1]])
>>> x2
array([[1, 2, 3, 3, 2, 1],

I got this error after using $.getJSON() from JQuery. I just changed to post:
data = getDataObjectByForm(form);
var jqxhr = $.post(url, data, function(){}, 'json')
.done(function (response) {
if (response instanceof Object)
var json = response;
else
var json = $.parseJSON(response);
// console.log(response);
// console.log(json);
jsonToDom(json);
if (json.reload != undefined && json.reload)
location.reload();
$("body").delay(1000).css("cursor", "default");
})
.fail(function (jqxhr, textStatus, error) {
var err = textStatus + ", " + error;
console.log("Request Failed: " + err);
alert("Fehler!");
});
Just write simple template:
template<typename T>
const char* getClassName(T) {
return typeid(T).name();
}
struct A {} a;
void main() {
std::cout << getClassName(a);
}
For example, your controller, retrive data and put the view
class ClassExampleController extends Controller
{
public function index()
{
$test = Test::first(1);
return view('view-form',[
'field' => $test,
]);
}
}
Add default value in the same form, create and edit, is very simple
<!-- view-form file -->
<form action="{{
isset($field) ?
@route('field.updated', $field->id) :
@route('field.store')
}}">
<!-- Input case -->
<input name="name_input" class="form-control"
value="{{ isset($field->name) ? $field->name : '' }}">
</form>
And, you remember add csrf_field, in case a POST method requesting. Therefore, repeat input, and select element, compare each option
<select name="x_select">
@foreach($field as $subfield)
@if ($subfield == $field->name)
<option val="i" checked>
@else
<option val="i" >
@endif
@endforeach
</select>
The package.json file is used by npm to learn about your node.js project.
Use npm init
to generate package.json files for you!
It comes bundled with npm. Read its documentation here: https://docs.npmjs.com/cli/init
Also, there's an official tool you can use to generate this file programmatically: https://github.com/npm/init-package-json
this works for me on windows 7. No need for intermediary sh scripts

JSONArray jsonArray = jsnobject.getJSONArray("locations");

Talking in terms of performance "2" (with JMH):
class A{}
class B extends A{}
public class InstanceOfTest {
public static final Object a = new A();
public static final Object b = new B();
@Benchmark
@BenchmarkMode(Mode.AverageTime)
@OutputTimeUnit(TimeUnit.NANOSECONDS)
public boolean testInstanceOf()
{
return b instanceof A;
}
@Benchmark
@BenchmarkMode(Mode.AverageTime)
@OutputTimeUnit(TimeUnit.NANOSECONDS)
public boolean testIsInstance()
{
return A.class.isInstance(b);
}
@Benchmark
@BenchmarkMode(Mode.AverageTime)
@OutputTimeUnit(TimeUnit.NANOSECONDS)
public boolean testIsAssignableFrom()
{
return A.class.isAssignableFrom(b.getClass());
}
public static void main(String[] args) throws RunnerException {
Options opt = new OptionsBuilder()
.include(InstanceOfTest.class.getSimpleName())
.warmupIterations(5)
.measurementIterations(5)
.forks(1)
.build();
new Runner(opt).run();
}
}
It gives:
Benchmark Mode Cnt Score Error Units
InstanceOfTest.testInstanceOf avgt 5 1,972 ? 0,002 ns/op
InstanceOfTest.testIsAssignableFrom avgt 5 1,991 ? 0,004 ns/op
InstanceOfTest.testIsInstance avgt 5 1,972 ? 0,003 ns/op
So that we can conclude: instanceof as fast as isInstance() and isAssignableFrom() not far away (+0.9% executon time). So no real difference whatever you choose
when you use the svn:// URI it uses port 3690 and probably won't use http proxy
jQuery now has a CDN access:
code.jquery.com/ui/[version]/themes/[theme name]/jquery-ui.css
And to make this a little more easy, Here you go:
Replace
curl_setopt($ch, CURLOPT_POSTFIELDS, array("customer"=>$data_string));
with:
$data_string = json_encode(array("customer"=>$data));
//Send blindly the json-encoded string.
//The server, IMO, expects the body of the HTTP request to be in JSON
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
I dont get what you meant by "other page", I hope it is the page at: 'url_to_post'. If that page is written in PHP, the JSON you just posted above will be read in the below way:
$jsonStr = file_get_contents("php://input"); //read the HTTP body.
$json = json_decode($jsonStr);
This can be done using httpPostedFileBase class returns the HttpInputStreamObject as per specified here
You should convert the stream into byte array and then you can read file content
Please refer following link
http://msdn.microsoft.com/en-us/library/system.web.httprequest.inputstream.aspx]
Hope this helps
UPDATE :
The stream that you get from your HTTP call is read-only sequential (non-seekable) and the FileStream is read/write seekable. You will need first to read the entire stream from the HTTP call into a byte array, then create the FileStream from that array.
Taken from here
// Read bytes from http input stream
BinaryReader b = new BinaryReader(file.InputStream);
byte[] binData = b.ReadBytes(file.ContentLength);
string result = System.Text.Encoding.UTF8.GetString(binData);
You can use the following two properties in "colors.xml"
<color name="colorControlNormal">#eeeeee</color>
<color name="colorControlActivated">#eeeeee</color>
colorControlNormal is for the normal view of checkbox, and colorControlActivated is for when the checkbox is checked.
Using regular ng-view
module you cannot have more than one dynamic template.
However, this project enables you to do so (look for ui-router
).
For reference purpose, for anyone searching how to change the path via code, I am quoting a useful post by a Delphi programmer from this web page: http://www.tek-tips.com/viewthread.cfm?qid=686382
TonHu (Programmer) 22 Oct 03 17:57 I found where I read the original posting, it's here: http://news.jrsoftware.org/news/innosetup.isx/msg02129....
The excerpt of what you would need is this:
You must specify the string "Environment" in LParam. In Delphi you'd do it this way:
SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, Integer(PChar('Environment')));
It was suggested by Jordan Russell, http://www.jrsoftware.org, the author of (a.o.) InnoSetup, ("Inno Setup is a free installer for Windows programs. First introduced in 1997, Inno Setup today rivals and even surpasses many commercial installers in feature set and stability.") (I just would like more people to use InnoSetup )

sadly, n
doesn't worked for me. I use node version manager or nvm
and it works like a charm. heres the link on how to install nvm
: https://github.com/creationix/nvm#installation
nvm i 8.11.2
upgrade to latest LTSnvm use 8.11.2
use itnode -v
check your latest versionI had a similar problem and just found a way to solve it (by single-stepping through log4j-extras
source, no less...)
The good news is that, unlike what's written everywhere, it turns out that you actually CAN configure TimeBasedRollingPolicy using log4j.properties (XML config not needed! At least in versions of log4j >1.2.16 see this bug report)
Here is an example:
log4j.appender.File = org.apache.log4j.rolling.RollingFileAppender
log4j.appender.File.rollingPolicy = org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.File.rollingPolicy.FileNamePattern = logs/worker-${instanceId}.%d{yyyyMMdd-HHmm}.log
BTW the ${instanceId}
bit is something I am using on Amazon's EC2 to distinguish the logs from all my workers -- I just need to set that property before calling PropertyConfigurator.configure()
, as follow:
p.setProperty("instanceId", EC2Util.getMyInstanceId());
PropertyConfigurator.configure(p);
# Replace the line of the given line number with the given replacement in the given file.
function replace-line-in-file() {
local file="$1"
local line_num="$2"
local replacement="$3"
# Escape backslash, forward slash and ampersand for use as a sed replacement.
replacement_escaped=$( echo "$replacement" | sed -e 's/[\/&]/\\&/g' )
sed -i "${line_num}s/.*/$replacement_escaped/" "$file"
}
If you want a comamnd that both accepts input from pipeline or as paramater, you should try this:
function which($name) {
if ($name) { $input = $name }
Get-Command $input | Select-Object -ExpandProperty Path
}
copy-paste the command to your profile (notepad $profile

I had a similar but different problem and still unable to work when I use $('#myModal'). I was able to get it working when I use $(window).
My other problem is that I found that the show event would not fire if I stored my modal div html content in a javascript variable like.
var content="<div id='myModal' ...";
$(content).modal();
$(window).on('show.bs.modal', function (e) {
alert('show test');
});
the event never fired because it didn't occur
my fix was to include the divs in the html body
<body>
<div id='myModal'>
...
</div>
<script>
$('#myModal).modal();
$(window).on('show.bs.modal', function (e) {
alert('show test');
});
</script>
</body>
If order is not important and you don't need to worry about duplicates then you can use set intersection:
>>> a = [1,2,3,4,5]
>>> b = [1,3,5,6]
>>> list(set(a) & set(b))
[1, 3, 5]
Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english
A small side note - stumbled upon this same error while developing a web application. The mistake we found, by toying with the service with Firefox Poster, was that both fields and values in the Json should be surrounded by double quotes. For instance..
[ {"idProductCategory" : "1" , "description":"Descrizione1"},
{"idProductCategory" : "2" , "description":"Descrizione2"} ]
In our case we filled the json via javascript, which can be a little confusing when it comes with dealing with single/double quotes, from what I've heard.
What's been said before in this and other posts, like including the 'Accept' and 'Content-Type' headers, applies too.
Hope t'helps.
You've almost done it. However setting flex: 0 0 <basis>
declaration to the columns would prevent them from growing/shrinking; And the <basis>
parameter would define the width of columns.
In addition, you could use CSS3 calc()
expression to specify the height
of columns with the respect to the height of the header.
#productShowcaseTitle {
flex: 0 0 100%; /* Let it fill the entire space horizontally */
height: 100px;
}
#productShowcaseDetail,
#productShowcaseThumbnailContainer {
height: calc(100% - 100px); /* excluding the height of the header */
}
#productShowcaseContainer {_x000D_
display: flex;_x000D_
flex-flow: row wrap;_x000D_
_x000D_
height: 600px;_x000D_
width: 580px;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_

}_x000D_
_x000D_
#productShowcaseDetail {_x000D_

Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div>
element, it would be achieved without using calc()
as follows:
<div class="contentContainer"> <!-- Added wrapper -->
<div id="productShowcaseDetail"></div>
<div id="productShowcaseThumbnailContainer"></div>
</div>
#productShowcaseContainer {
display: flex;
flex-direction: column;
height: 600px; width: 580px;
}
.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }
#productShowcaseContainer {_x000D_
display: flex;_x000D_
flex-direction: column;_x000D_
_x000D_
height: 600px;_x000D_
width: 580px;_x000D_
}_x000D_
_x000D_
.contentContainer {_x000D_
display: flex;_x000D_
flex: 1;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_

But from what I understand xs:choice still only allows single element selection. Hence setting the MaxOccurs to unbounded like this should only mean that "any one" of the child elements can appear multiple times. Is this accurate?
No. The choice happens individually for every "repetition" of xs:choice
that occurs due to maxOccurs="unbounded"
. Therefore, the code that you have posted is correct, and will actually do what you want as written.
I'm not sure you can exclude packages explicitly with an <exclude-filter>, but I bet using a regex filter would effectively get you there:
<context:component-scan base-package="com.example">
<context:exclude-filter type="regex" expression="com\.example\.ignore\..*"/>
</context:component-scan>
To make it annotation-based, you'd annotate each class you wanted excluded for integration tests with something like @com.example.annotation.ExcludedFromITests. Then the component-scan would look like:
<context:component-scan base-package="com.example">
<context:exclude-filter type="annotation" expression="com.example.annotation.ExcludedFromITests"/>
</context:component-scan>
That's clearer because now you've documented in the source code itself that the class is not intended to be included in an application context for integration tests.
Java 8 solution (like this but a bit simpler):
public static List<String> partition(String string, int partSize) {
List<String> parts = IntStream.range(0, string.length() / partSize)
.mapToObj(i -> string.substring(i * partSize, (i + 1) * partSize))
.collect(toList());
if ((string.length() % partSize) != 0)
parts.add(string.substring(string.length() / partSize * partSize));
return parts;
}
If you're doing this for manual validation of the data, you can do this with LINQPad.
Create a connection to the database in LinqPad then create C# statements similar to the following:
DataTable table = MyStoredProc (param1, param2).Tables[0];
(from row in table.AsEnumerable()
select new
{
Col1 = row.Field<string>("col1"),
Col2 = row.Field<string>("col2"),
}).Dump();
You can run advanced queries via AWS Config (and from the CLI for Config), that will list all resources. If you define an aggregator that covers all reasons (and perhaps multiple accounts), you can get a very comprehensive view . . . As simple as "SELECT *"

Guava also has Base64 (among other encodings and incredibly useful stuff)
At this point:
for (String[] s : myEntries) {
System.out.println("Next item: " + s);
}
You need to join the array of Strings in a line. Check this post: A method to reverse effect of java String.split()?
UPDATE: This question was the subject of my blog on May 12th 2011. Thanks for the great question!
Suppose you have an interface as you describe, and a hundred classes that implement it. Then you decide to make one of the parameters of one of the interface's methods optional. Are you suggesting that the right thing to do is for the compiler to force the developer to find every implementation of that interface method, and make the parameter optional as well?
Suppose we did that. Now suppose the developer did not have the source code for the implementation:
// in metadata:
public class B
{
public void TestMethod(bool b) {}
}
// in source code
interface MyInterface
{
void TestMethod(bool b = false);
}
class D : B, MyInterface {}
// Legal because D's base class has a public method
// that implements the interface method
How is the author of D supposed to make this work? Are they required in your world to call up the author of B on the phone and ask them to please ship them a new version of B that makes the method have an optional parameter?
That's not going to fly. What if two people call up the author of B, and one of them wants the default to be true and one of them wants it to be false? What if the author of B simply refuses to play along?
Perhaps in that case they would be required to say:
class D : B, MyInterface
{
public new void TestMethod(bool b = false)
{
base.TestMethod(b);
}
}
The proposed feature seems to add a lot of inconvenience for the programmer with no corresponding increase in representative power. What's the compelling benefit of this feature which justifies the increased cost to the user?
UPDATE: In the comments below, supercat suggests a language feature that would genuinely add power to the language and enable some scenarios similar to the one described in this question. FYI, that feature -- default implementations of methods in interfaces -- will be added to C# 8.
Shorter example using http.get:
require('http').get('http://httpbin.org/ip', (res) => {
res.setEncoding('utf8');
res.on('data', function (body) {
console.log(body);
});
});
Well, Pavel was close, but there's even a more simple and elegant solution to initialize a sequential container from a c style array.
In your case:
w_ (array, std::end(array))
Assuming having a template DataFrame, which one would like to copy with zero values filled here...
If you have no NaNs in your data set, multiplying by zero can be significantly faster:
In [19]: columns = ["col{}".format(i) for i in xrange(3000)]
In [20]: indices = xrange(2000)
In [21]: orig_df = pd.DataFrame(42.0, index=indices, columns=columns)
In [22]: %timeit d = pd.DataFrame(np.zeros_like(orig_df), index=orig_df.index, columns=orig_df.columns)
100 loops, best of 3: 12.6 ms per loop
In [23]: %timeit d = orig_df * 0.0
100 loops, best of 3: 7.17 ms per loop
Improvement depends on DataFrame size, but never found it slower.
And just for the heck of it:
In [24]: %timeit d = orig_df * 0.0 + 1.0
100 loops, best of 3: 13.6 ms per loop
In [25]: %timeit d = pd.eval('orig_df * 0.0 + 1.0')
100 loops, best of 3: 8.36 ms per loop
But:
In [24]: %timeit d = orig_df.copy()
10 loops, best of 3: 24 ms per loop
EDIT!!!
Assuming you have a frame using float64, this will be the fastest by a huge margin! It is also able to generate any value by replacing 0.0 to the desired fill number.
In [23]: %timeit d = pd.eval('orig_df > 1.7976931348623157e+308 + 0.0')
100 loops, best of 3: 3.68 ms per loop
Depending on taste, one can externally define nan, and do a general solution, irrespective of the particular float type:
In [39]: nan = np.nan
In [40]: %timeit d = pd.eval('orig_df > nan + 0.0')
100 loops, best of 3: 4.39 ms per loop
A quick update to Michael's excellent answer above.
For Rails 4.0+ you need to put your sort in a block like this:
class Book < ActiveRecord::Base
default_scope { order('created_at DESC') }
end
Notice that the order statement is placed in a block denoted by the curly braces.
They changed it because it was too easy to pass in something dynamic (like the current time). This removes the problem because the block is evaluated at runtime. If you don't use a block you'll get this error:
Support for calling #default_scope without a block is removed. For example instead of
default_scope where(color: 'red')
, please usedefault_scope { where(color: 'red') }
. (Alternatively you can just redefine self.default_scope.)
As @Dan mentions in his comment below, you can do a more rubyish syntax like this:
class Book < ActiveRecord::Base
default_scope { order(created_at: :desc) }
end
or with multiple columns:
class Book < ActiveRecord::Base
default_scope { order({begin_date: :desc}, :name) }
end
Thanks @Dan!

Check this useful method:
URLUtil.guessUrl(urlString)
It makes google.com -> http://google.com
In addition to global "editor.rulers"
setting, it's also possible to set this on a per-language level.
For example, style guides for Python projects often specify either 79 or 120 characters vs. Git commit messages should be no longer than 50 characters.
So in your settings.json
, you'd put:
"[git-commit]": {"editor.rulers": [50]},
"[python]": {
"editor.rulers": [
79,
120
]
}
If you push for example image to some API and want the result address(response) back you could do:
import requests
url = 'https://uguu.se/api.php?d=upload-tool'
data = {"name": filename}
files = {'file': open(full_file_path, 'rb')}
response = requests.post(url, data=data, files=files)
current_url = response.text
print(response.text)
If I'm not mistaken this is usually handled via a timeout.

Now you can run your web applications on server.
if you want to list all the containers name with the relevant volumes that attached to each container you can try this:
docker ps -q | xargs docker container inspect -f '{{ .Name }} {{ .HostConfig.Binds }}'
example output:
/opt_rundeck_1 [/opt/var/lib/mysql:/var/lib/mysql:rw /var/lib/rundeck/var/storage:/var/lib/rundeck/var/storage:rw /opt/var/rundeck/.ssh:/var/lib/rundeck/.ssh:rw /opt/etc/rundeck:/etc/rundeck:rw /var/log/rundeck:/var/log/rundeck:rw /opt/rundeck-plugins:/opt/rundeck-plugins:rw /opt/var/rundeck:/var/rundeck:rw]
/opt_rundeck_1 - container name
[..] - volumes attached to the conatiner
You can use round function. Here some example

array([ 21.53, 8.13, 3.97, 10.08])
IF you want change just display representation, I would not recommended to alter printing format globally, as it suggested above. I would format my output in place.
>>a=np.array([2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01])
>>> print([ "{:0.2f}".format(x) for x in a ])
['21.53', '8.13', '3.97', '10.08']
here's a native javascript inline code to change image onmouseover & onmouseout:

</a>
Definitely the HTML5 element is the way to go. There's at least basic support for it in the most recent versions of almost all browsers:
http://caniuse.com/#feat=audio
And it allows to specify what to do when the element is not supported by the browser. For example you could add a link to a file by doing:
<audio controls src="intro.mp3">
<a href="intro.mp3">Introduction to HTML5 (10:12) - MP3 - 3.2MB</a>
</audio>
You can find this examples and more information about the audio element in the following link:
http://hacks.mozilla.org/2012/04/enhanceyourhtml5appwithaudio/
Finally, the good news are that mozilla's April's dev Derby is about this element so that's probably going to provide loads of great examples of how to make the most out of this element:

const regex = new RegExp(`ReGeX${testVar}ReGeX`);
...
string.replace(regex, "replacement");
Per some of the comments, it's important to note that you may want to escape the variable if there is potential for malicious content (e.g. the variable comes from user input)
In 2019, this would usually be written using a template string, and the above code has been updated. The original answer was:
var regex = new RegExp("ReGeX" + testVar + "ReGeX");
...
string.replace(regex, "replacement");
Very elegant:
String.prototype.format = function (){
var args = arguments;
return this.replace(/\{\{|\}\}|\{(\d+)\}/g, function (curlyBrack, index) {
return ((curlyBrack == "{{") ? "{" : ((curlyBrack == "}}") ? "}" : args[index]));
});
};
// Usage:
"{0}{1}".format("{1}", "{0}")

Depends on your priorities.
If performance is your absolute driving characteristic, then by all means use the fastest one. Just make sure you have a full understanding of the differences before you make a choice
serialize()
you need to add extra parameter to keep UTF-8 characters untouched: json_encode($array, JSON_UNESCAPED_UNICODE)
(otherwise it converts UTF-8 characters to Unicode escape sequences).__sleep()
and __wakeup()
with JSONPHP>=5.4
you can implement JsonSerializable to change this behavior).And there's probably a few other differences I can't think of at the moment.
A simple speed test to compare the two

json_encode($testArray);
$jsonTime = microtime(true) - $start;

$serializeTime = microtime(true) - $start;
echo "PHP serialized in $serializeTime seconds\n";
// Compare them
if ($jsonTime < $serializeTime) {
printf("json_encode() was roughly %01.2f%% faster than serialize()\n", ($serializeTime / $jsonTime - 1) * 100);

You have a lot of variants for using @RequestParam
with additional optional elements, e.g.
@RequestParam(required = false, defaultValue = "someValue", value="someAttr") String someAttr
If you don't put required = false
- param will be required by default.
defaultValue = "someValue"
- the default value to use as a fallback when the request parameter is not provided or has an empty value.
If request and method param are the same - you don't need value = "someAttr"
First, create the derived value:
df.loc[0, 'C'] = df.loc[0, 'D']
Then iterate through the remaining rows and fill the calculated values:
for i in range(1, len(df)):
df.loc[i, 'C'] = df.loc[i-1, 'C'] * df.loc[i, 'A'] + df.loc[i, 'B']
Index_Date A B C D
0 2015-01-31 10 10 10 10
1 2015-02-01 2 3 23 22
2 2015-02-02 10 60 290 280
I had the same need for conditional tests, and I figured out a good workaround. I defined a macro TEST_C that works like a TEST_F macro, but it has a third parameter, which is a boolean expression, evaluated runtime in main.cpp BEFORE the tests are started. Tests that evaluate false are not executed. The macro is ugly, but it look like:
#pragma once
extern std::map<std::string, std::function<bool()> >* m_conditionalTests;
#define TEST_C(test_fixture, test_name, test_condition)\
class test_fixture##_##test_name##_ConditionClass\
{\
public:\
test_fixture##_##test_name##_ConditionClass()\
{\
std::string name = std::string(#test_fixture) + "." + std::string(#test_name);\
if (m_conditionalTests==NULL) {\
m_conditionalTests = new std::map<std::string, std::function<bool()> >();\
}\
m_conditionalTests->insert(std::make_pair(name, []()\
{\
DeviceInfo device = Connection::Instance()->GetDeviceInfo();\
return test_condition;\
}));\
}\
} test_fixture##_##test_name##_ConditionInstance;\
TEST_F(test_fixture, test_name)
Additionally, in your main.cpp, you need this loop to exclude the tests that evaluate false:
// identify tests that cannot run on this device
std::string excludeTests;
for (const auto& exclusion : *m_conditionalTests)
{
bool run = exclusion.second();
if (!run)
{
excludeTests += ":" + exclusion.first;
}
}
// add the exclusion list to gtest
std::string str = ::testing::GTEST_FLAG(filter);
::testing::GTEST_FLAG(filter) = str + ":-" + excludeTests;
// run all tests
int result = RUN_ALL_TESTS();
Since nobody said how to check if the file exists AND get the current folder the executable is in (Working Directory):
if (File.Exists(Directory.GetCurrentDirectory() + @"\YourFile.txt")) {
//do stuff
}
The @"\YourFile.txt"
is not case sensitive, that means stuff like @"\YoUrFiLe.txt"
and @"\YourFile.TXT"
or @"\yOuRfILE.tXt"
is interpreted the same.
If you are running SQL Server 2008 R2 the built in options on to do this in SSMS as marc_s described above changed a bit. Instead of selecting Script data = true
as shown in his diagram, there is now a new option called "Types of data to script"
just above the "Table/View Options" grouping. Here you can select to script data only, schema and data or schema only. Works like a charm.
The 'c' means it's a character special file.
I'd suggest window.open()
to open a popup window. If it's a download, there will be no window and you will get your file. If there is a 404 or something, the user will see it in a new window (hence, their work will not be bothered, but they will still get an error message).
You can use forever-service for doing this.
npm install -g forever-service
forever-service install test
This will provision app.js in the current directory as a service via forever. The service will automatically restart every time system is restarted. Also when stopped it will attempt a graceful stop. This script provisions the logrotate script as well.

Maybe you have no Comments record with such primary key, then you should use this code:
try:
comment = Comment.objects.get(pk=comment_id)
except Comment.DoesNotExist:
comment = None

Given the Django use case, there are two answers to this. Here is its django.utils.html.escape
function, for reference:
def escape(html):
"""Returns the given HTML with ampersands, quotes and carets encoded."""
return mark_safe(force_unicode(html).replace('&', '&').replace('<', '&l
t;').replace('>', '>').replace('"', '"').replace("'", '''))
To reverse this, the Cheetah function described in Jake's answer should work, but is missing the single-quote. This version includes an updated tuple, with the order of replacement reversed to avoid symmetric problems:
def html_decode(s):
"""
Returns the ASCII decoded version of the given HTML string. This does
NOT remove normal HTML tags like <p>.
"""
htmlCodes = (
("'", '''),
('"', '"'),
('>', '>'),
('<', '<'),
('&', '&')
)
for code in htmlCodes:
s = s.replace(code[1], code[0])
return s
unescaped = html_decode(my_string)
This, however, is not a general solution; it is only appropriate for strings encoded with django.utils.html.escape
. More generally, it is a good idea to stick with the standard library:
# Python 2.x:
import HTMLParser
html_parser = HTMLParser.HTMLParser()
unescaped = html_parser.unescape(my_string)
# Python 3.x:
import html.parser
html_parser = html.parser.HTMLParser()
unescaped = html_parser.unescape(my_string)
# >= Python 3.5:
from html import unescape
unescaped = unescape(my_string)
As a suggestion: it may make more sense to store the HTML unescaped in your database. It'd be worth looking into getting unescaped results back from BeautifulSoup if possible, and avoiding this process altogether.
With Django, escaping only occurs during template rendering; so to prevent escaping you just tell the templating engine not to escape your string. To do that, use one of these options in your template:
{{ context_var|safe }}
{% autoescape off %}
{{ context_var }}
{% endautoescape %}
The apply
function takes two arguments; the object this
will be binded to, and the arguments, represented with an array.
some_func = function (a, b) { return b }
some_func.apply(obj, ["arguments", "are", "here"])
// "are"

I always prefer let
to an instance variable for a couple of reasons:
nil
, which can lead to subtle bugs and false positives. Since let
creates a method, you'll get a NameError
when you misspell it, which I find preferable. It makes it easier to refactor specs, too.before(:each)
hook will run before each example, even if the example doesn't use any of the instance variables defined in the hook. This isn't usually a big deal, but if the setup of the instance variable takes a long time, then you're wasting cycles. For the method defined by let
, the initialization code only runs if the example calls it.@
).let
and keeping my it
block nice and short.A related link can be found here: http://www.betterspecs.org/#let
To add to the problem, how to extend this formatting to process extra spaces between words of the string.
Actually, this is a simpler case than accounting for multiple leading and trailing white-space characters. All you need to do is remove duplicate adjacent white-space characters from the entire string.
The predicate for adjacent white space would simply be:
auto by_space = [](unsigned char a, unsigned char b) {
return std::isspace(a) and std::isspace(b);
};
and then you can get rid of those duplicate adjacent white-space characters with std::unique
, and the erase-remove idiom:
// s = " This is a sample string "
s.erase(std::unique(std::begin(s), std::end(s), by_space),
std::end(s));
// s = " This is a sample string "
This does potentially leave an extra white-space character at the front and/or the back. This can be removed quite easily:
if (std::size(s) && std::isspace(s.back()))
s.pop_back();
if (std::size(s) && std::isspace(s.front()))
s.erase(0, 1);
Here's a demo.
I found that the Windows Defender Antimalware is causing huge delays. Go to Update & Security -> Settings -> Windows Defender. Open the Defender and in the Settings selection, choose Exclusions and add the "devenv.exe' process. It worked for me
To run or debug tests in Visual Studio 2017, we need to install "NUnit3TestAdapter". We can install it in any version of Visual Studio, but it is working properly in the Visual Studio "community" version.
To install this, you can add it through the NuGet package.
import java.io.*;
import java.util.Scanner;
class ar1 {
public static void main(String[] args) {
//Scanner sc=new Scanner(System.in);
int[] a={10,20,30,40,12,32};
int bi=0,sm=0;
//bi=sc.nextInt();
//sm=sc.nextInt();
for(int i=0;i<=a.length-1;i++) {
if(a[i]>a[i+1])
bi=a[i];
if(a[i]<a[i+1])
sm=a[i];
}
System.out.println("big"+bi+"small"+sm);
}
}

You can do as many Outlines as you like, and there's enough scope for coming up with lots of creative ideas.

You should use what your FPGA documentation recommends. There is no portable way to initialize register values other than using a reset net. This has a hardware cost associated with it on most synthesis targets.

If you use Express 4.x, you can use the req.get(headerName)

I had the same problem,
<body id="body">
Add an ID tag to the body:
$('#body').attr('class',json.class); // My class comes from Ajax/JSON, but change it to whatever you require.
Then switch the class for the body's using the id. This has been tested in Chrome, Internet Explorer, and Safari.
It's important to keep in mind that the MapReduce framework in Hadoop allows us only to
suggest the number of Map tasks for a job
which like Praveen pointed out above will correspond to the number of input splits for the task. Unlike it's behavior for the number of reducers (which is directly related to the number of files output by the MapReduce job) where we can
demand that it provide n reducers.
You could use the following, provided String s
is the string you want to process.
Map<Character,Integer> map = new HashMap<Character,Integer>();
for (int i = 0; i < s.length(); i++) {
char c = s.charAt(i);
if (map.containsKey(c)) {
int cnt = map.get(c);
map.put(c, ++cnt);
} else {
map.put(c, 1);
}
}
Note, it will count all of the chars, not only letters.
Your regular expression most likely wants to be
/\nSUMMARY:(.*)$/g
A helpful little trick I like to use is to default assign on match with an array.
var arr = iCalContent.match(/\nSUMMARY:(.*)$/g) || [""]; //could also use null for empty value
return arr[0];
This way you don't get annoying type errors when you go to use arr
Decimal representation of floating point numbers is kind of strange. If you have a number with 15 decimal places and convert that to a double
, then print it out with exactly 15 decimal places, you should get the same number. On the other hand, if you print out an arbitrary double
with 15 decimal places and the convert it back to a double
, you won't necessarily get the same value back—you need 17 decimal places for that. And neither 15 nor 17 decimal places are enough to accurately display the exact decimal equivalent of an arbitrary double
. In general, you need over 100 decimal places to do that precisely.
See the Wikipedia page for double-precision and this article on floating-point precision.
You have conditions that are mutually exclusive - if meta_key is 'first_name', it can't also be 'yearofpassing'. Most likely you need your AND's to be OR's:
$result = mysql_query("SELECT user_id FROM wp_usermeta
WHERE (meta_key = 'first_name' AND meta_value = '$us_name')
OR (meta_key = 'yearofpassing' AND meta_value = '$us_yearselect')
OR (meta_key = 'u_city' AND meta_value = '$us_reg')
OR (meta_key = 'us_course' AND meta_value = '$us_course')")

vlado.grigorov has some good advice - the best way is to create a backgroundView, and give that a colour, setting everything else to the clearColor. Also, I think that way is the only way to correctly clear the colour (try his sample - but set 'clearColor' instead of 'yellowColor'), which is what I was trying to do.
Make sure both drive have the same partition - ( like FAT or NTFS, preferably NTFS ) also make sure he NETWORK SERVICE account, has the access.
You didn't specify what shell you are using, but with zsh you could use the =( )
construct to achieve this. Something along the lines of:
cp =(sed ... file; sync) file
=( )
is similar to >( )
but creates a temporary file which is automatically deleted when cp
terminates.
