This topic is confusing because there are 3 terms in use when people think there are just 2, namely:
"bit rate": units are bits per second
"baud": units are symbols per second
"Baud rate": units are bits per second
"Baud rate" is really a marketing term rather than an engineering term. "Baud rate" was used by modem manufactures in a similar way to megapixels is used for digital cameras. So the higher the "Baud rate" the better the modem was perceived to be.
The engineering unit "baud" is already a rate (symbols per second) which distinguishes it from the "Baud rate" term. However, you can see from the answers that people are confusing these 2 terms together such as baud/sec which is wrong.
From an engineering point of view, I recommend people use the term "bit rate" for "RS-232" and consign to history the term "Baud rate". Use the term "baud" for modulation schemes but avoid it for "RS-232".
In other words, "bit rate" and "Baud rate" are the same thing which means how many bits are transmitted along a wire in one second. Note that bits per second (bps) is the low-level line rate and not the information data rate because asynchronous "RS-232" has start and stop bits that frame the 8 data bits of information so bps includes all bits transmitted.
It's worth mentioning that you'll sometimes see void 0
when checking for undefined, simply because it requires fewer characters.
For example:
if (something === undefined) {
doSomething();
}
Compared to:
if (something === void 0) {
doSomething();
}
Some minification methods replace undefined
with void 0
for this reason.
from the terminal type:-
aws configure
then fill in your keys and region.
after this do next step use any environment. You can have multiple keys depending your account. Can manage multiple enviroment or keys
import boto3
aws_session = boto3.Session(profile_name="prod")
# Create an S3 client
s3 = aws_session.client('s3')
Visual Studio 2020 version
In tasks.json
file, (after you build and debug with the g++-9
)
Add -std=c++2a
for 2020 features (c++1z
for 2017 features).
Add -fconcepts
to use concept
keyword
"args": [
"-std=c++2a",
"-fconcepts",
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
now compile and you can use the 2020 features.
Use Reflection:
Type type = obj.GetType();
PropertyInfo[] properties = type.GetProperties();
foreach (PropertyInfo property in properties)
{
Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(obj, null));
}
for Excel - what tools/reference item must be added to gain access to BindingFlags, as there is no "System.Reflection" entry in the list
Edit: You can also specify a BindingFlags value to type.GetProperties()
:
BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
PropertyInfo[] properties = type.GetProperties(flags);
That will restrict the returned properties to public instance properties (excluding static properties, protected properties, etc).
You don't need to specify BindingFlags.GetProperty
, you use that when calling type.InvokeMember()
to get the value of a property.

In the other question I suggested autoexnt. That is also possible in this situation. Just set the service to run manually (ie not automatic at startup). When you want to run your batch, modify the autoexnt.bat file to call the batch file you want, and start the autoexnt service.
The batchfile to start this, can look like this (untested):
echo call c:\path\to\batch.cmd %* > c:\windows\system32\autoexnt.bat
net start autoexnt
Note that batch files started this way run as the system user, which means you do not have access to network shares automatically. But you can use net use to connect to a remote server.
You have to download the Windows 2003 Resource Kit to get it. The Resource Kit can also be installed on other versions of windows, like Windows XP.
This worked for me:
DECLARE @SQL NVARCHAR(4000)
DECLARE @tbl Table (
Id int,
Account varchar(50),
Amount int
)
-- Lots of code to Create my dynamic sql statement
insert into @tbl EXEC sp_executesql @SQL
select * from @tbl
Try to change this: <csrf />
to this : <csrf disabled="true"/>
. It should disable csfr.
If you want the external public IP and you're in a cloud environment like AWS or Azure, you can use the ipify_facts module:
# TODO: SECURITY: This requires that we trust ipify to provide the correct public IP. We could run our own ipify server.
- name: Get my public IP from ipify.org
ipify_facts:
This will place the public IP into the variable ipify_public_ip
.
In XML, xmlns declares a Namespace. In fact, when you do:
<LinearLayout android:id>
</LinearLayout>
Instead of calling android:id
, the xml will use http://schemas.android.com/apk/res/android:id to be unique. Generally this page doesn't exist (it's a URI, not a URL), but sometimes it is a URL that explains the used namespace.
The namespace has pretty much the same uses as the package name in a Java application.
Here is an explanation.
Uniform Resource Identifier (URI)
A Uniform Resource Identifier (URI) is a string of characters which identifies an Internet Resource.
The most common URI is the Uniform Resource Locator (URL) which identifies an Internet domain address. Another, not so common type of URI is the Universal Resource Name (URN).
In our examples we will only use URLs.

Although Chris Baxter's answer helps with original problem, it doesn't work in my case when application is hosted in virtual directory. After investigating the options, I finished with DIY solution.
ProperStyleBundle
class includes code borrowed from original CssRewriteUrlTransform
to properly transform relative paths within virtual directory. It also throws if file doesn't exist and prevents reordering of files in the bundle (code taken from BetterStyleBundle
).

_basePath = basePath.EndsWith( "/" ) ? basePath : VirtualPathUtility.GetDirectory( basePath );
}
public string Process( string includedVirtualPath, string input )
{
if ( includedVirtualPath == null ) {
throw new ArgumentNullException( "includedVirtualPath" );
}
return ConvertUrlsToAbsolute( _basePath, input );
}
private static string RebaseUrlToAbsolute( string baseUrl, string url )
{
if ( string.IsNullOrWhiteSpace( url )
|| string.IsNullOrWhiteSpace( baseUrl )
|| url.StartsWith( "/", StringComparison.OrdinalIgnoreCase )
|| url.StartsWith( "data:", StringComparison.OrdinalIgnoreCase )
) {
return url;
}
if ( !baseUrl.EndsWith( "/", StringComparison.OrdinalIgnoreCase ) ) {
baseUrl = baseUrl + "/";
}
return VirtualPathUtility.ToAbsolute( baseUrl + url );
}
private static string ConvertUrlsToAbsolute( string baseUrl, string content )

What you want to do is a combination of part of 1 and all of 2.
You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.
But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.
From the javadoc:
Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.
The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.
Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:
import static org.mockito.Mockito.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
class ClassWithStatics {
public static String getString() {
return "String";
}
public static int getInt() {
return 1;
}
}
@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
@Test
public void test() {
PowerMockito.mockStatic(ClassWithStatics.class);
when(ClassWithStatics.getString()).thenReturn("Hello!");
System.out.println("String: " + ClassWithStatics.getString());
System.out.println("Int: " + ClassWithStatics.getInt());
}
}
The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.
final String url = "some/url";
instead of:
final JSONObject jsonBody = "{\"type\":\"example\"}";
you can use:
JSONObject jsonBody = new JSONObject();
try {
jsonBody.put("type", "my type");
} catch (JSONException e) {
e.printStackTrace();
}
new JsonObjectRequest(url, jsonBody, new Response.Listener<JSONObject>() { ... });
I got the same problem after updating my mac on Osx Movaje.
i found this solution :
Try first the bellow command line in your terminal :
brew services restart postgresql
If nothing change :
ps aux | grep postgres
If still nothing change :
ls -ls | grep post
Last command to fix it, removed the postgres lock file by executing from root :
rm /usr/local/var/postgres/postmaster.pid
and then :
brew services restart postgresql

This is the way to add more file extentions, in the example given by Roy M J in the top of this page.
var fileextension = [".png", ".jpg"];
$(data).find("a:contains(" + (fileextension[0]) + "), a:contains(" + (fileextension[1]) + ")").each(function () { // here comes the rest of the function made by Roy M J
In this example I have added more contains.
Can a modulus be negative?
%
can be negative as it is the remainder operator, the remainder after division, not after Euclidean_division. Since C99 the result may be 0, negative or positive.
// a % b
7 % 3 --> 1
7 % -3 --> 1
-7 % 3 --> -1
-7 % -3 --> -1
The modulo OP wanted is a classic Euclidean modulo, not %
.
I was expecting a positive result every time.
To perform a Euclidean modulo that is well defined whenever a/b
is defined, a,b
are of any sign and the result is never negative:
int modulo_Euclidean(int a, int b) {
int m = a % b;
if (m < 0) {
// m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
m = (b < 0) ? m - b : m + b;
}
return m;
}
modulo_Euclidean( 7, 3) --> 1
modulo_Euclidean( 7, -3) --> 1
modulo_Euclidean(-7, 3) --> 2
modulo_Euclidean(-7, -3) --> 2
Image.fromarray -> returns an image object
from PIL import Image
import numpy as np
PIL_image = Image.fromarray(np.uint8(numpy_image)).convert('RGB')
PIL_image = Image.fromarray(numpy_image.astype('uint8'), 'RGB')
This is what I've been using for development:
<?xml version="1.0" ?>
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>
This is a very liberal approach, but is fine for my application.
As others have pointed out below, beware the risks of this.
From the error, I infer that referenceElement
is a dictionary (see repro below). A dictionary cannot be hashed and therefore cannot be used as a key to another dictionary (or itself for that matter!).
>>> d1, d2 = {}, {}
>>> d1[d2] = 1
Traceback (most recent call last):
File "<input>", line 1, in <module>
TypeError: unhashable type: 'dict'
You probably meant either for element in referenceElement.keys()
or for element in json['referenceElement'].keys()
. With more context on what types json
and referenceElement
are and what they contain, we will be able to better help you if neither solution works.
My solution for ie detection:
if (navigator.userAgent.match(/msie/i) || navigator.userAgent.match(/trident/i) ){
$("html").addClass("ie");
}
Jquery needed.
Backspace and tab both move the cursor position. Neither is truly a 'printable' character.
Your code says:
To get the output you expect, you need printf("foo\b \tbar")
. Note the extra 'space'. That says:
Most of the time it is inappropriate to use tabs and backspace for formatting your program output. Learn to use printf()
formatting specifiers. Rendering of tabs can vary drastically depending on how the output is viewed.
This little script shows one way to alter your terminal's tab rendering. Tested on Ubuntu + gnome-terminal:
#!/bin/bash
tabs -8
echo -e "\tnormal tabstop"
for x in `seq 2 10`; do
tabs $x
echo -e "\ttabstop=$x"
done
tabs -8
echo -e "\tnormal tabstop"
Also see man setterm
and regtabs
.
And if you redirect your output or just write to a file, tabs will quite commonly be displayed as fewer than the standard 8 chars, especially in "programming" editors and IDEs.
So in otherwords:
printf("%-8s%s", "foo", "bar"); /* this will ALWAYS output "foo bar" */
printf("foo\tbar"); /* who knows how this will be rendered */
IMHO, tabs in general are rarely appropriate for anything. An exception might be generating output for a program that requires tab-separated-value input files (similar to comma separated value).
Backspace '\b'
is a different story... it should never be used to create a text file since it will just make a text editor spit out garbage. But it does have many applications in writing interactive command line programs that cannot be accomplished with format strings alone. If you find yourself needing it a lot, check out "ncurses", which gives you much better control over where your output goes on the terminal screen. And typically, since it's 2011 and not 1995, a GUI is usually easier to deal with for highly interactive programs. But again, there are exceptions. Like writing a telnet server or console for a new scripting language.
In the header file define a base class:
class BaseClass {
public:
BaseClass(params);
};
Then define a derived class as inheriting the BaseClass:
class DerivedClass : public BaseClass {
public:
DerivedClass(params);
};
In the source file define the BaseClass constructor:
BaseClass::BaseClass(params)
{
//Perform BaseClass initialization
}
By default the derived constructor only calls the default base constructor with no parameters; so in this example, the base class constructor is NOT called automatically when the derived constructor is called, but it can be achieved simply by adding the base class constructor syntax after a colon (:
). Define a derived constructor that automatically calls its base constructor:
DerivedClass::DerivedClass(params) : BaseClass(params)
{
//This occurs AFTER BaseClass(params) is called first and can
//perform additional initialization for the derived class
}
The BaseClass
constructor is called BEFORE the DerivedClass
constructor, and the same/different parameters params
may be forwarded to the base class if desired. This can be nested for deeper derived classes. The derived constructor must call EXACTLY ONE base constructor. The destructors are AUTOMATICALLY called in the REVERSE order that the constructors were called.
EDIT: There is an exception to this rule if you are inheriting from any virtual
classes, typically to achieve multiple inheritance or diamond inheritance. Then you MUST explicitly call the base constructors of all virtual
base classes and pass the parameters explicitly, otherwise it will only call their default constructors without any parameters. See: virtual inheritance - skipping constructors

Can you run your JNI-using Java application from a console window (launch it from a java command line) to see if there is any report of what may have been detected before the JVM was crashed. When running directly as a Java window application, you may be missing messages that would appear if you ran from a console window instead.
Secondly, can you stub your JNI DLL implementation to show that methods in your DLL are being entered from JNI, you are returning properly, etc?
Just in case the problem is with an incorrect use of one of the JNI-interface methods from the C++ code, have you verified that some simple JNI examples compile and work with your setup? I'm thinking in particular of using the JNI-interface methods for converting parameters to native C++ formats and turning function results into Java types. It is useful to stub those to make sure that the data conversions are working and you are not going haywire in the COM-like calls into the JNI interface.
There are other things to check, but it is hard to suggest any without knowing more about what your native Java methods are and what the JNI implementation of them is trying to do. It is not clear that catching an exception from the C++ code level is related to your problem. (You can use the JNI interface to rethrow the exception as a Java one, but it is not clear from what you provide that this is going to help.)

Try this, in this JS we can check if it is post back or not and accordingly do operations in the respective loops.
window.onload = isPostBack;
function isPostBack() {
if (!document.getElementById('clientSideIsPostBack')) {

if (document.getElementById('clientSideIsPostBack').value == 'Y') {
***// DO ALL POST BACK RELATED WORK HERE***
return true;
}
else {
***// DO ALL INITIAL LOAD RELATED WORK HERE***
return false;
}
}
If you want to use values from other columns in your JSON update command you can use string concatenation:

SQL Server may be able to suggest the right data type for you (even when it does not choose the right type by default) - clicking the "Suggest Types" button (shown in your screenshot above) allows you to have SQL Server scan the source and suggest a data type for the field that's throwing an error. In my case, choosing to scan 20000 rows to generate the suggestions, and using the resulting suggested data type, fixed the issue.
I have always been a fan of WinMerge which is an open source project. You can plug it into Visual Studio fairly easily.
will show you how to do this
Your example code essentially asks why the example program doesn't trap, and the answer is that memory protection is a kernel feature and applies only to entire pages, whereas the memory allocator is a library feature and it manages .. without enforcement .. arbitrary sized blocks which are often much smaller than pages.
Memory can only be removed from your program in units of pages, and even that is unlikely to be observed.
calloc(3) and malloc(3) do interact with the kernel to get memory, if necessary. But most implementations of free(3) do not return memory to the kernel1, they just add it to a free list that calloc() and malloc() will consult later in order to reuse the released blocks.
Even if a free() wanted to return memory to the system, it would need at least one contiguous memory page in order to get the kernel to actually protect the region, so releasing a small block would only lead to a protection change if it was the last small block in a page.
So your block is there, sitting on the free list. You can almost always access it and nearby memory just as if it were still allocated. C compiles straight to machine code and without special debugging arrangements there are no sanity checks on loads and stores. Now, if you try and access a free block, the behavior is undefined by the standard in order to not make unreasonable demands on library implementators. If you try and access freed memory or meory outside an allocated block, there are various things that can go wrong:
So, working backwards from your example to the overall theory, malloc(3) gets memory from the kernel when it needs it, and typically in units of pages. These pages are divided or consolidated as the program requires. Malloc and free cooperate to maintain a directory. They coalesce adjacent free blocks when possible in order to be able to provide large blocks. The directory may or may not involve using the memory in freed blocks to form a linked list. (The alternative is a bit more shared-memory and paging-friendly, and it involves allocating memory specifically for the directory.) Malloc and free have little if any ability to enforce access to individual blocks even when special and optional debugging code is compiled into the program.
1. The fact that very few implementations of free() attempt to return memory to the system is not necessarily due to the implementors slacking off. Interacting with the kernel is much slower than simply executing library code, and the benefit would be small. Most programs have a steady-state or increasing memory footprint, so the time spent analyzing the heap looking for returnable memory would be completely wasted. Other reasons include the fact that internal fragmentation makes page-aligned blocks unlikely to exist, and it's likely that returning a block would fragment blocks to either side. Finally, the few programs that do return large amounts of memory are likely to bypass malloc() and simply allocate and free pages anyway.
Try using @Html.DropDownList
instead:
<td>Account: </td>
<td>@Html.DropDownList("accountid", new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))</td>
@Html.DropDownListFor
expects a lambda as its first argument, not a string
for the ID as you specify.
Other than that, without knowing what getUserAccounts()
consists of, suffice to say it needs to return some sort of collection (IEnumerable
for example) that has at least 1 object in it. If it returns null
the property in the ViewBag won't have anything.

The Thread
class is used for creating and manipulating a thread in Windows.
A Task
represents some asynchronous operation and is part of the Task Parallel Library, a set of APIs for running tasks asynchronously and in parallel.
In the days of old (i.e. before TPL) it used to be that using the Thread
class was one of the standard ways to run code in the background or in parallel (a better alternative was often to use a ThreadPool
), however this was cumbersome and had several disadvantages, not least of which was the performance overhead of creating a whole new thread to perform a task in the background.
Nowadays using tasks and the TPL is a far better solution 90% of the time as it provides abstractions which allows far more efficient use of system resources. I imagine there are a few scenarios where you want explicit control over the thread on which you are running your code, however generally speaking if you want to run something asynchronously your first port of call should be the TPL.
Apple has provided an extension for the UIImage class called UIImage+ImageEffects.h. In this class you have the desired methods for blurring your view
Ran into the similar problem not exactly the same, A case of Database already existed the issue was solved by following code.

I would like to run an automation test in different environments.
So I add this to command maven command:
spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=productionEnv1"
Here is the link where I found the solution: [1]https://github.com/spring-projects/spring-boot/issues/1095
Yes you can use simply
$input_data = $_POST;
or extract() may be useful for you.
rm -f .git/index
git reset

Here's the code by Sinetheta converted to a jQuery plugin: Save below code to a js file.
$.fn.collapsible = function() {
$(this).addClass("ui-accordion ui-widget ui-helper-reset");
var headers = $(this).children("h3");
headers.addClass("accordion-header ui-accordion-header ui-helper-reset ui-state-active ui-accordion-icons ui-corner-all");
headers.append('<span class="ui-accordion-header-icon ui-icon ui-icon-triangle-1-s">');
headers.click(function() {
var header = $(this);
var panel = $(this).next();
var isOpen = panel.is(":visible");
if(isOpen) {
panel.slideUp("fast", function() {
panel.hide();
header.removeClass("ui-state-active")
.addClass("ui-state-default")
.children("span").removeClass("ui-icon-triangle-1-s")
.addClass("ui-icon-triangle-1-e");
});
}
else {
panel.slideDown("fast", function() {
panel.show();
header.removeClass("ui-state-default")
.addClass("ui-state-active")
.children("span").removeClass("ui-icon-triangle-1-e")
.addClass("ui-icon-triangle-1-s");
});
}
});
};
Refer it in your UI page and call similar to jQuery accordian call:
$("#accordion").collapsible();
Looks cleaner and avoids any classes to be added to the markup.
Add a property to the form method="post"
.
Like this:
<form name="loginform" method="post">
Also, some very interesting information further on lists vs. arrays in Python ~> Python List vs. Array - when to use?
It could be noted that once I convert my arrays into a list before saving it in a JSON file, in my deployment right now anyways, once I read that JSON file for use later, I can continue to use it in a list form (as opposed to converting it back to an array).
AND actually looks nicer (in my opinion) on the screen as a list (comma seperated) vs. an array (not-comma seperated) this way.
Using @travelingbones's .tolist() method above, I've been using as such (catching a few errors I've found too):
SAVE DICTIONARY
def writeDict(values, name):
writeName = DIR+name+'.json'
with open(writeName, "w") as outfile:
json.dump(values, outfile)
READ DICTIONARY
def readDict(name):
readName = DIR+name+'.json'
try:
with open(readName, "r") as infile:
dictValues = json.load(infile)
return(dictValues)
except IOError as e:
print(e)
return('None')
except ValueError as e:
print(e)
return('None')
Hope this helps!
Translate with ord() and unichar(). Every unicode char have a number asociated, something like an index. So Python have a few methods to translate between a char and his number. Downside is a ñ example. Hope it can help.
>>> C = 'ñ'
>>> U = C.decode('utf8')
>>> U
u'\xf1'
>>> ord(U)
241
>>> unichr(241)
u'\xf1'
>>> print unichr(241).encode('utf8')
ñ
What fixed it for me was right clicking on project > Maven > Update Project
This may also be achieved using matplotlib.pyplot.quiver
, as noted in the linked answer;
plt.quiver([0, 0, 0], [0, 0, 0], [1, -2, 4], [1, 2, -7], angles='xy', scale_units='xy', scale=1)
plt.xlim(-10, 10)
plt.ylim(-10, 10)
plt.show()
Sometimes this happens when you download a project from github or other third party tutorial sites.These apps are usually signed with a different identity or company/name.When this happens,if you can't solve the solution,simply create a new xcode project and copy all the header and implementation files into your new project.Also don't forget the dependency files..such as the framework files.This works for me.
You can do the following:
Python 2.x
import hashlib
print hashlib.md5("whatever your string is").hexdigest()
Python 3.x
import hashlib
print(hashlib.md5("whatever your string is".encode('utf-8')).hexdigest())
However in this case you're probably better off using this helpful Python module for interacting with the Flickr API:
... which will deal with the authentication for you.
Official documentation of hashlib
^[+-]?(([1-9][0-9]*)?[0-9](\.[0-9]*)?|\.[0-9]+)$
should reflect what people usually think of as a well formed decimal number.
The digits before the decimal point can be either a single digit, in which case it can be from 0 to 9, or more than one digits, in which case it cannot start with a 0.
If there are any digits present before the decimal sign, then the decimal and the digits following it are optional. Otherwise, a decimal has to be present followed by at least one digit. Note that multiple trailing 0's are allowed after the decimal point.
grep -E '^[+-]?(([1-9][0-9]*)?[0-9](\.[0-9]*)?|\.[0-9]+)$'
correctly matches the following:
9
0
10
10.
0.
0.0
0.100
0.10
0.01
10.0
10.10
.0
.1
.00
.100
.001
as well as their signed equivalents, whereas it rejects the following:
.
00
01
00.0
01.3
and their signed equivalents, as well as the empty string.
When you run cmake add the additional parameter -D OPENCV_GENERATE_PKGCONFIG=YES (this will generate opencv.pc file)
Then make and sudo make install as before.
Use the name opencv4 instead of just opencv Eg:-
pkg-config --modversion opencv4
moment(dateString, 'YYYY-MM-DD', true).isValid() ||
moment(dateString, 'YYYY-M-DD', true).isValid() ||
moment(dateString, 'YYYY-MM-D', true).isValid();
I know that what I do is quite the workaround, however it works perfectly and that is the way I do it everytime.
Then, proceed like this:
Cheers!
The following algorithm will deal with self-referential data structures, numbers, strings, dates, and of course plain nested javascript objects:
Objects are considered equivalent when
===
(String and Number are unwrapped first to ensure 42
is equivalent to Number(42)
)valueOf()
==
(catches numbers/strings/booleans)undefined
value they have the same properties all of which are considered recursively equivalent.Functions are not considered identical by function text. This test is insufficient because functions may have differing closures. Functions are only considered equal if ===
says so (but you could easily extend that equivalent relation should you choose to do so).
Infinite loops, potentially caused by circular datastructures, are avoided. When areEquivalent
attempts to disprove equality and recurses into an object's properties to do so, it keeps track of the objects for which this sub-comparison is needed. If equality can be disproved, then some reachable property path differs between the objects, and then there must be a shortest such reachable path, and that shortest reachable path cannot contain cycles present in both paths; i.e. it is OK to assume equality when recursively comparing objects. The assumption is stored in a property areEquivalent_Eq_91_2_34
, which is deleted after use, but if the object graph already contains such a property, behavior is undefined. The use of such a marker property is necessary because javascript doesn't support dictionaries using arbitrary objects as keys.
function unwrapStringOrNumber(obj) {
return (obj instanceof Number || obj instanceof String
? obj.valueOf()
: obj);
}
function areEquivalent(a, b) {
a = unwrapStringOrNumber(a);
b = unwrapStringOrNumber(b);
if (a === b) return true; //e.g. a and b both null
if (a === null || b === null || typeof (a) !== typeof (b)) return false;
if (a instanceof Date)
return b instanceof Date && a.valueOf() === b.valueOf();
if (typeof (a) !== "object")
return a == b; //for boolean, number, string, xml
var newA = (a.areEquivalent_Eq_91_2_34 === undefined),
newB = (b.areEquivalent_Eq_91_2_34 === undefined);
try {
if (newA) a.areEquivalent_Eq_91_2_34 = [];
else if (a.areEquivalent_Eq_91_2_34.some(
function (other) { return other === b; })) return true;
if (newB) b.areEquivalent_Eq_91_2_34 = [];
else if (b.areEquivalent_Eq_91_2_34.some(
function (other) { return other === a; })) return true;
a.areEquivalent_Eq_91_2_34.push(b);
b.areEquivalent_Eq_91_2_34.push(a);
var tmp = {};
for (var prop in a)
if(prop != "areEquivalent_Eq_91_2_34")
tmp[prop] = null;
for (var prop in b)
if (prop != "areEquivalent_Eq_91_2_34")
tmp[prop] = null;
for (var prop in tmp)
if (!areEquivalent(a[prop], b[prop]))
return false;
return true;
} finally {
if (newA) delete a.areEquivalent_Eq_91_2_34;
if (newB) delete b.areEquivalent_Eq_91_2_34;
}
}
You can quote if you like, or you can escape the spaces with a preceding \, but most UNIX paths (Mac OS X aside) don't have spaces in them.
/Applications/Image\ Capture.app/Contents/MacOS/Image\ Capture
"/Applications/Image Capture.app/Contents/MacOS/Image Capture"
/Applications/"Image Capture.app"/Contents/MacOS/"Image Capture"
All refer to the same executable under Mac OS X.
I'm not sure what you mean about recognizing a path - if any of the above paths are passed as a parameter to a program the shell will put the entire string in one variable - you don't have to parse multiple arguments to get the entire path.
another bit of code here:
refer: https://github.com/stvnthomas/CodeIgniter-Multi-Upload
That because your csv file is in invalid format, maybe the line break in your text file is not the \n or \r
and, using c/c++ to parse text is not a good idea. try awk:
$awk -F"," '{print "ID="$1"\tName="$2"\tAge="$3"\tGender="$4}' 1.csv
ID=0 Name=Filipe Age=19 Gender=M
ID=1 Name=Maria Age=20 Gender=F
ID=2 Name=Walter Age=60 Gender=M
I don't think you can turn JavaScript objects into JSON strings using only jQuery, assuming you need the JSON string as output.
Depending on the browsers you are targeting, you can use the JSON.stringify
function to produce JSON strings.
See http://www.json.org/js.html for more information, there you can also find a JSON parser for older browsers that don't support the JSON object natively.
In your case:
var array = [];
$("input[class=email]").each(function() {
array.push({
title: $(this).attr("title"),
email: $(this).val()
});
});
// then to get the JSON string
var jsonString = JSON.stringify(array);
That's not possible using the built-in Array.prototype.map
. However, you could use a simple for
-loop instead, if you do not intend to map
any values:
var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
if (myArray[i] < 10) {
hasValueLessThanTen = true;
break;
}
}
Or, as suggested by @RobW
, use Array.prototype.some
to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:
var hasValueLessThanTen = myArray.some(function (val) {
return val < 10;
});
Use the following command to get connected to your MySQL database
mysql -u USERNAME -h HOSTNAME -p
For me shutil.copy is the best:
import shutil
#make a copy of the invoice to work with
src="invoice.pdf"
dst="copied_invoice.pdf"
shutil.copy(src,dst)
You can change the path of the files as you want.
I realise this is an old post, but in case it helps, you can apply this CSS to have IE11 draw a dotted outline for the focus indication of a <select>
element so that it resembles Firefox's focus indication:
select:focus::-ms-value {
background: transparent;
color: inherit;
outline-style: dotted;
outline-width: thin;
}
Well, to answer the immediate question:
>>> s = "http://www.domain.com/?s=some&two=20"
The rfind
method returns the index of right-most substring:
>>> s.rfind("&")
29
You can take all elements up to a given index with the slicing operator:
>>> "foobar"[:4]
'foob'
Putting the two together:
>>> s[:s.rfind("&")]
'http://www.domain.com/?s=some'
If you are dealing with URLs in particular, you might want to use built-in libraries that deal with URLs. If, for example, you wanted to remove two
from the above query string:
First, parse the URL as a whole:
>>> import urlparse, urllib
>>> parse_result = urlparse.urlsplit("http://www.domain.com/?s=some&two=20")
>>> parse_result
SplitResult(scheme='http', netloc='www.domain.com', path='/', query='s=some&two=20', fragment='')
Take out just the query string:
>>> query_s = parse_result.query
>>> query_s
's=some&two=20'
Turn it into a dict
:
>>> query_d = urlparse.parse_qs(parse_result.query)
>>> query_d
{'s': ['some'], 'two': ['20']}
>>> query_d['s']
['some']
>>> query_d['two']
['20']
Remove the 'two'
key from the dict:
>>> del query_d['two']
>>> query_d
{'s': ['some']}
Put it back into a query string:
>>> new_query_s = urllib.urlencode(query_d, True)
>>> new_query_s
's=some'
And now stitch the URL back together:
>>> result = urlparse.urlunsplit((
parse_result.scheme, parse_result.netloc,
parse_result.path, new_query_s, parse_result.fragment))
>>> result
'http://www.domain.com/?s=some'
The benefit of this is that you have more control over the URL. Like, if you always wanted to remove the two
argument, even if it was put earlier in the query string ("two=20&s=some"
), this would still do the right thing. It might be overkill depending on what you want to do.
There are a number of different icons and even splash screens that you can set for various devices. This answer goes through how to support them all.
Here are some snippets I have used with relevant links to where I gathered the information. See my blog for more information and more information about the ASP.NET MVC Boilerplate project template with all this built in right out of the box (Including sample image files).
Add the following mark-up to your html head. The commented out sections are entirely optional. While the uncommented sections are recommended to cover all icon usages. Don't be scared, most if it is comments to help you.

Total Overhead
If you take out the comments that's 3KB of extra HTML, if you don't support splash screens that's 1.5KB. If you are using GZIP compression on your HTML content, which everyone should be doing these days, that leaves you with about 634 Bytes of overhead per request to support all platforms or 446 Bytes without splash screens. I personally think its worth it to support IOS, Android and Windows devices but its your choice, I'm just giving the options!
Side Note About The Current Web Icon/Splash Screen/Settings Situation
This situation with vendor specific icons, splash screens and special tags to control the web browser or pinned icons is ridiculous. In a perfect world we would all use a favicon.svg file which could look good at any size and could be placed at the root of the page. Only FireFox supports this at the time of writing (See CanIUse.com).
However, icons are not the only setting these days, there are several other vendor specific settings (shown above) but a favicon.svg file would cover most use cases.
Update
Updated to include the new Android/Chrome version M39+ favicon/theming options. Interestingly, they have gone with a similar approach to Microsoft but are using a JSON file instead of XML.
Your activity must have
public void insertIntoDb(View v) {
...
}
not Fragment .
If you don't want the above in activity. initialize button in fragment and set listener to the same.
<Button
android:id="@+id/btn_conferma" // + missing
Then
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_rssitem_detail,
container, false);
Button button = (Button) view.findViewById(R.id.btn_conferma);
button.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// do something
}
});
return view;
}

I just had a similar problem.
The reason was that I was changing a file.aspx.c and had to do a clean rebuild. After that everything worked.
Another trick to add to your arsenal is the following:
$ grep -r "Copyright" /<path-to-source-files>/src
Generally speaking, if one changes a file they should claim credit in the “Copyright”. Examine the results for dates, file names, contributors and contact email.
example grep result:
/<path>/src/someobject.h: * Copyright 2007-2012 <creator's name> <creator's email>(at)<some URL>>
Directory Services/LDAP lookups can be used to serve this purpose. It involves some changes at infrastructure level, but most production environments have such provision
This rule
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o producer.o consumer.o AddRemove.o
is wrong. It says to create a file named producer.o (with -o producer.o
), but you want to create a file named main
. Please excuse the shouting, but ALWAYS USE $@ TO REFERENCE THE TARGET:
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o $@ producer.o consumer.o AddRemove.o
As Shahbaz rightly points out, the gmake professionals would also use $^
which expands to all the prerequisites in the rule. In general, if you find yourself repeating a string or name, you're doing it wrong and should use a variable, whether one of the built-ins or one you create.
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o $@ $^
THIS CAN BE A QUICK FIX FOR ECLIPSE
When I was trying to create array list it gave error that array list cannot be resolved to type and something about "parametrised type are only in level 1.5"
Only I did was I tried to import java.util.ArrayList;
And that error went away.
It is cumbersome and difficult to specify locale explicitly
. You never know where your app will be used. So I think, it is better to set locale
to Calender.current.locale
and use DateFormatter
's
setLocalizedDateFormatFromTemplate
method.
Sets the date format from a template using the specified locale for the receiver. - developer.apple.com
extension Date {
func convertToLocaleDate(template: String) -> String {
let dateFormatter = DateFormatter()
let calender = Calendar.current
dateFormatter.timeZone = calender.timeZone
dateFormatter.locale = calender.locale
dateFormatter.setLocalizedDateFormatFromTemplate(template)
return dateFormatter.string(from: self)
}
}
Date().convertToLocaleDate(template: "dd MMMM YYYY")

Here's a nice, tidy solution for you: (also see the live demo ->)
window.onload = function start() {
slide();
}
function slide() {
var currMarg = 0,
contStyle = document.getElementById('container').style;
setInterval(function() {
currMarg = currMarg == 1800 ? 0 : currMarg + 600;
contStyle.marginLeft = '-' + currMarg + 'px';
}, 3000);
}
Since you are trying to learn, allow me to explain how this works.
First we declare two variables: currMarg
and contStyle
. currMarg
is an integer that we will use to track/update what left margin the container should have. We declare it outside the actual update function (in a closure), so that it can be continuously updated/access without losing its value. contStyle
is simply a convenience variable that gives us access to the containers styles without having to locate the element on each interval.
Next, we will use setInterval
to establish a function which should be called every 3 seconds, until we tell it to stop (there's your infinite loop, without freezing the browser). It works exactly like setTimeout
, except it happens infinitely until cancelled, instead of just happening once.
We pass an anonymous function to setInterval
, which will do our work for us. The first line is:
currMarg = currMarg == 1800 ? 0 : currMarg + 600;
This is a ternary operator. It will assign currMarg
the value of 0
if currMarg
is equal to 1800
, otherwise it will increment currMarg
by 600
.
With the second line, we simply assign our chosen value to container
s marginLeft, and we're done!
Note: For the demo, I changed the negative values to positive, so the effect would be visible.

I realize my opinion is probably not the popular one, but I guess I have a hard time jumping on the Linq-y band wagon. It's nifty. It's condensed. I get that and I'm not opposed to using it where it's appropriate. Maybe it's just me, but I feel like people have stopped thinking about creating utility functions to accomplish what they want and instead prefer to litter their code with (sometimes) excessively long lines of Linq code for the sake of creating a dense 1-liner.
I'm not saying that any of the Linq answers that people have provided here are bad, but I guess I feel like there is the potential that these single lines of code can start to grow longer and more obscure as you need to handle various situations. What if your array is null? What if you want a delimited string instead of just purely concatenated? What if some of the integers in your array are double-digit and you want to pad each value with leading zeros so that the string for each element is the same length as the rest?
Taking one of the provided answers as an example:
result = arr.Aggregate(string.Empty, (s, i) => s + i.ToString());
If I need to worry about the array being null, now it becomes this:
result = (arr == null) ? null : arr.Aggregate(string.Empty, (s, i) => s + i.ToString());
If I want a comma-delimited string, now it becomes this:
result = (arr == null) ? null : arr.Skip(1).Aggregate(arr[0].ToString(), (s, i) => s + "," + i.ToString());
This is still not too bad, but I think it's not obvious at a glance what this line of code is doing.
Of course, there's nothing stopping you from throwing this line of code into your own utility function so that you don't have that long mess mixed in with your application logic, especially if you're doing it in multiple places:
public static string ToStringLinqy<T>(this T[] array, string delimiter)
{
// edit: let's replace this with a "better" version using a StringBuilder
//return (array == null) ? null : (array.Length == 0) ? string.Empty : array.Skip(1).Aggregate(array[0].ToString(), (s, i) => s + "," + i.ToString());
return (array == null) ? null : (array.Length == 0) ? string.Empty : array.Skip(1).Aggregate(new StringBuilder(array[0].ToString()), (s, i) => s.Append(delimiter).Append(i), s => s.ToString());
}
But if you're going to put it into a utility function anyway, do you really need it to be condensed down into a 1-liner? In that case why not throw in a few extra lines for clarity and take advantage of a StringBuilder so that you're not doing repeated concatenation operations:
public static string ToStringNonLinqy<T>(this T[] array, string delimiter)
{
if (array != null)
{
// edit: replaced my previous implementation to use StringBuilder
if (array.Length > 0)
{
StringBuilder builder = new StringBuilder();
builder.Append(array[0]);
for (int i = 1; i < array.Length; i++)
{
builder.Append(delimiter);
builder.Append(array[i]);
}
return builder.ToString()
}
else
{
return string.Empty;
}
}
else
{
return null;
}
}
And if you're really so concerned about performance, you could even turn it into a hybrid function that decides whether to do string.Join or to use a StringBuilder depending on how many elements are in the array (this is a micro-optimization, not worth doing in my opinion and possibly more harmful than beneficial, but I'm using it as an example for this problem):
public static string ToString<T>(this T[] array, string delimiter)
{
if (array != null)
{
// determine if the length of the array is greater than the performance threshold for using a stringbuilder
// 10 is just an arbitrary threshold value I've chosen
if (array.Length < 10)
{
// assumption is that for arrays of less than 10 elements
// this code would be more efficient than a StringBuilder.
// Note: this is a crazy/pointless micro-optimization. Don't do this.
string[] values = new string[array.Length];
for (int i = 0; i < values.Length; i++)
values[i] = array[i].ToString();
return string.Join(delimiter, values);
}
else
{
// for arrays of length 10 or longer, use a StringBuilder
StringBuilder sb = new StringBuilder();
sb.Append(array[0]);
for (int i = 1; i < array.Length; i++)
{
sb.Append(delimiter);
sb.Append(array[i]);
}
return sb.ToString();
}
}
else
{
return null;
}
}
For this example, the performance impact is probably not worth caring about, but the point is that if you are in a situation where you actually do need to be concerned with the performance of your operations, whatever they are, then it will most likely be easier and more readable to handle that within a utility function than using a complex Linq expression.
That utility function still looks kind of clunky. Now let's ditch the hybrid stuff and do this:
// convert an enumeration of one type into an enumeration of another type
public static IEnumerable<TOut> Convert<TIn, TOut>(this IEnumerable<TIn> input, Func<TIn, TOut> conversion)
{
foreach (TIn value in input)
{
yield return conversion(value);
}
}
// concatenate the strings in an enumeration separated by the specified delimiter
public static string Delimit<T>(this IEnumerable<T> input, string delimiter)
{
IEnumerator<T> enumerator = input.GetEnumerator();
if (enumerator.MoveNext())
{
StringBuilder builder = new StringBuilder();
// start off with the first element
builder.Append(enumerator.Current);
// append the remaining elements separated by the delimiter
while (enumerator.MoveNext())
{
builder.Append(delimiter);
builder.Append(enumerator.Current);
}
return builder.ToString();
}
else
{
return string.Empty;
}
}
// concatenate all elements
public static string ToString<T>(this IEnumerable<T> input)
{
return ToString(input, string.Empty);
}
// concatenate all elements separated by a delimiter
public static string ToString<T>(this IEnumerable<T> input, string delimiter)
{
return input.Delimit(delimiter);
}
// concatenate all elements, each one left-padded to a minimum length
public static string ToString<T>(this IEnumerable<T> input, int minLength, char paddingChar)
{
return input.Convert(i => i.ToString().PadLeft(minLength, paddingChar)).Delimit(string.Empty);
}
Now we have separate and fairly compact utility functions, each of which are arguable useful on their own.
Ultimately, my point is not that you shouldn't use Linq, but rather just to say don't forget about the benefits of creating your own utility functions, even if they are small and perhaps only contain a single line that returns the result from a line of Linq code. If nothing else, you'll be able to keep your application code even more condensed than you could achieve with a line of Linq code, and if you are using it in multiple places, then using a utility function makes it easier to adjust your output in case you need to change it later.
For this problem, I'd rather just write something like this in my application code:
int[] arr = { 0, 1, 2, 3, 0, 1 };
// 012301
result = arr.ToString<int>();
// comma-separated values
// 0,1,2,3,0,1
result = arr.ToString(",");
// left-padded to 2 digits
// 000102030001
result = arr.ToString(2, '0');

Since Marco's answer is deprecated, you must use the following syntax (according jasonlfunk's comment) :
$client = new \GuzzleHttp\Client();
$response = $client->request('POST', 'http://www.example.com/user/create', [
'form_params' => [
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword',
]
]);
$response = $client->request('POST', 'http://www.example.com/files/post', [
'multipart' => [
[
'name' => 'file_name',
'contents' => fopen('/path/to/file', 'r')
],
[
'name' => 'csv_header',
'contents' => 'First Name, Last Name, Username',
'filename' => 'csv_header.csv'
]
]
]);
// PUT
$client->put('http://www.example.com/user/4', [
'body' => [
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword',
],
'timeout' => 5
]);
// DELETE
$client->delete('http://www.example.com/user');
Usefull for long server operations.
$client = new \GuzzleHttp\Client();
$promise = $client->requestAsync('POST', 'http://www.example.com/user/create', [
'form_params' => [
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword',
]
]);
$promise->then(
function (ResponseInterface $res) {
echo $res->getStatusCode() . "\n";
},
function (RequestException $e) {
echo $e->getMessage() . "\n";
echo $e->getRequest()->getMethod();
}
);
According to documentation, you can set headers :
// Set various headers on a request
$client->request('GET', '/get', [
'headers' => [
'User-Agent' => 'testing/1.0',
'Accept' => 'application/json',
'X-Foo' => ['Bar', 'Baz']
]
]);
If you want more details information, you can use debug
option like this :
$client = new \GuzzleHttp\Client();
$response = $client->request('POST', 'http://www.example.com/user/create', [
'form_params' => [
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword',
],
// If you want more informations during request
'debug' => true
]);
Documentation is more explicits about new possibilities.

Do not forget the . at the end, which indicates end of line
In C# 9 Microsoft will introduce a new way to have properties set only on initialization using the init;
method like so:
public class Person
{
public string firstName { get; init; }
public string lastName { get; init; }
}
This way, you can assign values when initializing a new object:
var person = new Person
{
firstname = "John",
lastName = "Doe"
}
But later on, you cannot change it:
person.lastName = "Denver"; // throws a compiler error
This could be pretty ugly, but doesn't Chrome use the NPAPI for plugins like Safari? In that case, you could write a wrapper plugin with the NPAPI that made the appropriate ActiveX creation and calls to run the plugin. If you do a lot of scripting against those plugins, you might have to be a bit of work to proxy those calls through to the wrapped ActiveX control.
Although dated, not one answer on this thread can be used universally. Using rgba to create transparent color masks - that doesn't exactly explain how to do so with background images.
My solution works for background images or color backgrounds.

Some conventions list all the public methods first, and then all the private ones - that means it's easy to separate the API from the implementation, even when there's no interface involved, if you see what I mean.
Another idea is to group related methods together - this makes it easier to spot seams where you could split your existing large class into several smaller, more targeted ones.
Another reason for PHP to return http code 0 is timeout. In my case, I had the following configuration:
curl_setopt($http, CURLOPT_TIMEOUT_MS,500);
It turned out that the request to the endpoint I was pointing to always took more than 500 ms, always timing out and always returning http code 0.
If you remove this setting (CURLOPT_TIMEOUT_MS) or put a higher value (in my case 5000), you'll get the actual http code, in my case a 200 (as expected).

ANSWER: Read the instructions #dua
Ok the magic was in this line that I apparently missed when installing was:
$ sudo apt-get install mongodb-10gen=2.4.6
And the full process as described here http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ is
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
$ echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
$ sudo apt-get update
$ sudo apt-get install mongodb-10gen
$ sudo apt-get install mongodb-10gen=2.2.3
$ echo "mongodb-10gen hold" | sudo dpkg --set-selections
$ sudo service mongodb start
$ mongod --version
db version v2.4.6
Wed Oct 16 12:21:39.938 git version: b9925db5eac369d77a3a5f5d98a145eaaacd9673
IMPORTANT: Make sure you change 2.4.6 to the latest version (or whatever you want to install). Find the latest version number here http://www.mongodb.org/downloads
Another solution is to use a RangeValidator where you set Type="Integer"
like this:
<asp:RangeValidator runat="server"
id="valrNumberOfPreviousOwners"
ControlToValidate="txtNumberOfPreviousOwners"
Type="Integer"
MinimumValue="0"
MaximumValue="999"
CssClass="input-error"
ErrorMessage="Please enter a positive integer."
Display="Dynamic">
</asp:RangeValidator>
You can set reasonable values for the MinimumValue
and MaximumValue
attributes too.
The solution is to call dependency:tree with the artifact's pom.xml file:
mvn -f "$HOME/.m2/repository/$POM_PATH" dependency:tree
See also How to list the transitive dependencies of an artifact from a repository?
Something like this would do:
xargs cat <filenames.txt
The xargs
program reads its standard input, and for each line of input runs the cat
program with the input lines as argument(s).
If you really want to do this in a loop, you can:
for fn in `cat filenames.txt`; do
echo "the next file is $fn"
cat $fn
done
onCreate()
method gets called when activity gets created, and its called only once in whole Activity life cycle.
where as onStart()
is called when activity is stopped... I mean it has gone to background and its onStop()
method is called by the os. onStart()
may be called multiple times in Activity life cycle.More details here
Since git 2.23 (August 2019) you now have a shortcut to do that: git restore --staged [filepath]
.
With this command, you could ignore a conflicted file without needing to add and remove that.
Example:
> git status
...
Unmerged paths:
(use "git add <file>..." to mark resolution)
both modified: file.ex
> git restore --staged file.ex
> git status
...
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: file.ex
That's the non-null assertion operator. It is a way to tell the compiler "this expression cannot be null
or undefined
here, so don't complain about the possibility of it being null
or undefined
." Sometimes the type checker is unable to make that determination itself.
It is explained here:
A new
!
post-fix expression operator may be used to assert that its operand is non-null and non-undefined in contexts where the type checker is unable to conclude that fact. Specifically, the operationx!
produces a value of the type ofx
withnull
andundefined
excluded. Similar to type assertions of the forms<T>x
andx as T
, the!
non-null assertion operator is simply removed in the emitted JavaScript code.
I find the use of the term "assert" a bit misleading in that explanation. It is "assert" in the sense that the developer is asserting it, not in the sense that a test is going to be performed. The last line indeed indicates that it results in no JavaScript code being emitted.
You can do:
foo.instance_of?(String)
And the more general:
foo.kind_of?(String)
My jQuery plugin enables the "resize" event on all elements not just the window
.
https://github.com/dustinpoissant/ResizeTriggering
$("#myElement") .resizeTriggering().on("resize", function(e){
// Code to handle resize
});
Yeah, for most cases, you don't need to create a class with getters and setters. Just create a new Dictionary and bind it to the data source. Here's an example in VB using a for loop to set the DisplayMember and ValueMember of a combo box from a list:
Dim comboSource As New Dictionary(Of String, String)()
cboMenu.Items.Clear()
For I = 0 To SomeList.GetUpperBound(0)
comboSource.Add(SomeList(I).Prop1, SomeList(I).Prop2)
Next I
cboMenu.DataSource = New BindingSource(comboSource, Nothing)
cboMenu.DisplayMember = "Value"
cboMenu.ValueMember = "Key"
Then you can set up a data grid view's rows according to the value or whatever you need by calling a method on click:
Private Sub cboMenu_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cboMenu.SelectionChangeCommitted
SetListGrid(cboManufMenu.SelectedValue)
End Sub
I think this is the most readable solution:
($("div.printArea") as any).printArea();
It seems the problem is you send the form request to welcome/do_upload
, and call the Welcome::do_upload()
method in another one by $this->do_upload()
.
Hence when you call the $this->do_upload();
within your second method, the $_FILES
array would be empty.
And that's why var_dump($data['upload_data']);
returns NULL
.
If you want to upload the file from welcome/second_method
, send the form request to the welcome/second_method where you call $this->do_upload();
.
Then change the form helper function (within the View) as follows1:
// Change the 'second_method' to your method name
echo form_open_multipart('welcome/second_method');
CodeIgniter has documented the Uploading process very well, by using the File Uploading library.
You could take a look at the sample code in the user guide; And also, in order to get a better understanding of the uploading configs, Check the Config items Explanation section at the end of the manual page.
Also there are couple of articles/samples about the file uploading in CodeIgniter, you might want to consider:
Just as a side-note: Make sure that you've loaded the url
and form
helper functions before using the CodeIgniter sample code:
// Load the helper files within the Controller
$this->load->helper('form');
$this->load->helper('url');
1. The form must be "multipart" type for file uploading. Hence you should use form_open_multipart()
helper function which returns:
<form method="post" action="controller/method" enctype="multipart/form-data" />

From your computer, run Charles:
Open Proxy Settings: Proxy -> Proxy Settings, Proxies Tab, check "Enable transparent HTTP proxying", and remember "Port" in heart.
SSL Proxy Settings:Proxy -> SSL Proxy Settings, SSL Proxying tab, Check “enable SSL Proxying”, and add . to Locations:
Open Access Control Settings: Proxy -> Access Control Settings. Add your local subnet to authorize machines on you local network to use the proxy from another machine/mobile.
In Android Phone:
Configure your mobile: Go to Settings -> Wireless & networks -> WiFi -> Connect or modify your network, fill in the computer IP address and Port(8888):
Get Charles SSL Certificate. Visit this url from your mobile browser: http://charlesproxy.com/getssl
In “Name the certificate” enter whatever you want
Accept the security warning and install the certificate. If you install it successful, then you probably see sth like that: In your phone, Settings -> Security -> Trusted credentials:

You need to delete your old db folder and recreate new one. It will resolve your issue.
No, there is no better way.
Actually you have an error in your pattern. What you want is:
DecimalFormat df = new DecimalFormat("#.00");
Note the "00"
, meaning exactly two decimal places.
If you use "#.##"
(#
means "optional" digit), it will drop trailing zeroes - ie new DecimalFormat("#.##").format(3.0d);
prints just "3"
, not "3.00"
.
Use a delimiter to separate the values.
<select name="myValues">
<option value="one|two">
</select>
<?php>
$value = filter_input(INPUT_POST, 'myValues');
$exploded_value = explode('|', $value);
$value_one = $exploded_value[0];
$value_two = $exploded_value[1];
?>
Here is a quick addition to the “Math” object in javascript to add a “average” command to it!!
Math.average = function(input) {
this.output = 0;
for (this.i = 0; this.i < input.length; this.i++) {
this.output+=Number(input[this.i]);
}
return this.output/input.length;
}
Then i have this addition to the “Math” object for getting the sum!
Math.sum = function(input) {
this.output = 0;
for (this.i = 0; this.i < input.length; this.i++) {
this.output+=Number(input[this.i]);
}
return this.output;
}
So then all you do is
alert(Math.sum([5,5,5])); //alerts “15”
alert(Math.average([10,0,5])); //alerts “5”
And where i put the placeholder array just pass in your variable (The input if they are numbers can be a string because of it parsing to a number!)
Just setting json
option to true
, the body will contain the parsed json:
request({
url: 'http://...',
json: true
}, function(error, response, body) {
console.log(body);
});
Maybe the condition you are using is incorrect:
$str1 == "taste" && $str2 == "waste"
The program will enter into THEN
part only when both of the stated conditions are true.
You can try with $str1 == "taste" || $str2 == "waste"
. This will execute the THEN
part if anyone of the above conditions are true.
During the install of python make sure you have "Install for all users" selected. Uninstall python and do a custom install and check "Install for all users".
There are 3 solutions available for these.
1) Enable remote login using below command - sudo systemsetup -setremotelogin on
2) In Mac, go to System Preference -> Sharing -> enable Remote Login that's it. 100% working solution
3) Final and most important solution is - Check your private area network connection . Sometime remote login isn't allow inside the local area network.

. given a path, how can we recursively create all the folders necessary to create the file .. for that path
Creates all directories and subdirectories as specified by path.
Directory.CreateDirectory(path);
then you may create a file.
try this code [updated]:
Scanner scan = null;
int range, smallest = 0, input;
for(;;){
boolean error=false;
scan = new Scanner(System.in);
System.out.print("Enter an integer between 1-100: ");
if(!scan.hasNextInt()) {
System.out.println("Invalid input!");
continue;
}
range = scan.nextInt();
if(range < 1) {
System.out.println("Invalid input!");
error=true;
}
if(error)
{
//do nothing
}
else
{
break;
}
}
for(int ii = 1; ii <= range; ii++) {
scan = new Scanner(System.in);
System.out.print("Enter value " + ii + ": ");
if(!scan.hasNextInt()) {
System.out.println("Invalid input!");
ii--;
continue;
}
}
You can create an array with the size set to a variable, i.e.
int size = 50;
string[] words = new string[size]; // contains 50 strings
However, that size can't change later on, if you decide you need 100 words. If you need the size to be really dynamic, you'll need to use a different sort of data structure. Try List
.
Adding to assylias's answer - assylias shows us D.ITEMS is a method that returns an array. Knowing that, we don't need the variant array a(i) [See caveat below]. We just need to use the proper array syntax.
For i = 0 To d.Count - 1
s = d.Items()(i)
Debug.Print s
Next i()
KEYS works the same way
For i = 0 To d.Count - 1
Debug.Print d.Keys()(i), d.Items()(i)
Next i
This syntax is also useful for the SPLIT function which may help make this clearer. SPLIT also returns an array with lower bounds at 0. Thus, the following prints "C".
Debug.Print Split("A,B,C,D", ",")(2)
SPLIT is a function. Its parameters are in the first set of parentheses. Methods and Functions always use the first set of parentheses for parameters, even if no parameters are needed. In the example SPLIT returns the array {"A","B","C","D"}. Since it returns an array we can use a second set of parentheses to identify an element within the returned array just as we would any array.
Caveat: This shorter syntax may not be as efficient as using the variant array a() when iterating through the entire dictionary since the shorter syntax invokes the dictionary's Items method with each iteration. The shorter syntax is best for plucking a single item by number from a dictionary.
If you want use RegEx in .NET,
Regex rx = new Regex(@"^([\w]+)(\-)*");
var match = rx.Match("thisis-thefirst");
var text = match.Groups[1].Value;
Assert.AreEqual("thisis", text);
As you have already stated in your question you have more than one option. A very basic approach would be using the tag referencing your PHP file in the method attribute. However as esoteric as it may sound AJAX is a more complete approach. Considering that an AJAX call (in combination with jQuery) can be as simple as:
$.post("yourfile.php", {data : "This can be as long as you want"});
And you get a more flexible solution, for example triggering a function after the server request is completed. Hope this helps.
You can copy the HTML svg tag from the website, then paste the code on a new html file and rename the extension to svg. It worked for me. Hope it helps you.
For Access, you can use the SQL Select query I present here:
For example you have this table:
888 || T800 ARNOLD || [email protected]
123 || JOHN CONNOR || [email protected]
125 || SARAH CONNOR ||[email protected]
And you need to select only distinct mails. You can do it with this:
SQL SELECT:
SELECT MAX(p.CLIENTE) AS ID_CLIENTE
, (SELECT TOP 1 x.NOMBRES
FROM Rep_Pre_Ene_MUESTRA AS x
WHERE x.MAIL=p.MAIL
AND x.CLIENTE=(SELECT MAX(l.CLIENTE) FROM Rep_Pre_Ene_MUESTRA AS l WHERE x.MAIL=l.MAIL)) AS NOMBRE,
p.MAIL
FROM Rep_Pre_Ene_MUESTRA AS p
GROUP BY p.MAIL;
You can use this to select the maximum ID, the correspondent name to that maximum ID , you can add any other attribute that way. Then at the end you put the distinct column to filter and you only group it with that last distinct column.
This will bring you the maximum ID with the correspondent data, you can use min or any other functions and you replicate that function to the sub-queries.
This select will return:
888 || T800 ARNOLD || [email protected]
125 || SARAH CONNOR ||[email protected]
Remember to index the columns you select and the distinct column must have not numeric data all in upper case or in lower case, or else it won't work. This will work with only one registered mail as well. Happy coding!!!
I changed this:
public string ByteArrToString(byte[] byteArr)
{
byte val;
string tempStr = "";
for (int i = 0; i <= byteArr.GetUpperBound(0); i++)
{
val = byteArr[i];
if (val < (byte)10)
tempStr += "00" + val.ToString();
else if (val < (byte)100)
tempStr += "0" + val.ToString();
else
tempStr += val.ToString();
}
return tempStr;
}
to this:
public string ByteArrToString(byte[] byteArr)
{
string temp = "";
foreach (byte b in byteArr)
temp += b.ToString().PadLeft(3, '0');
return temp;
}
The easiest way nowadays is to use PHP configure:

Additionally, if you have multiple columns to insert and want to check if they exists or not use the following code
Insert Into [Competitors] (cName, cCity, cState)
Select cName, cCity, cState from
(
select new.* from
(
select distinct cName, cCity, cState
from [Competitors] s, [City] c, [State] s
) new
left join
(
select distinct cName, cCity, cState
from [Competitors] s
) existing
on new.cName = existing.cName and new.City = existing.City and new.State = existing.State
where existing.Name is null or existing.City is null or existing.State is null
)

For junit4! This question deserves a new answer written for junit5.
I realise this answer is written a couple years after the question, probably this feature wasn't around then. But now, it's easy to just do this:
@Test
public void test_array_pass()
{
List<String> actual = Arrays.asList("fee", "fi", "foe");
List<String> expected = Arrays.asList("fee", "fi", "foe");
assertThat(actual, is(expected));
assertThat(actual, is(not(expected)));
}
If you have a recent version of Junit installed with hamcrest, just add these imports:

No, the clue is in the M - it's a Markup Language.
When peer close, you just do not know whether it just stop sending or both sending and receiving.Because TCP allows this, btw, you should know the difference between close and shutdown. If peer both stop sending and receiving, first you send some bytes, it will succeed. But the peer kernel will send you RST. So subsequently you send some bytes, your kernel will send you SIGPIPE signal, if you catch or ignore this signal, when your send returns, you just get Broken pipe error, or if you don't , the default behavior of your program is crashing.
Maybe this would perform a bit better in case greater amount of input data does not contain your wanted piece because except has greater cost.

I solved similar problem this way:
@Component
public class DataLoader {
@Autowired
private UserRepository userRepository;
//method invoked during the startup
@PostConstruct
public void loadData() {
userRepository.save(new User("user"));
}
//method invoked during the shutdown
@PreDestroy
public void removeData() {
userRepository.deleteAll();
}
}
Your return data
approach is correct, that's an example of promise chaining. If you return a promise from your .then()
callback, JavaScript will resolve that promise and pass the data to the next then()
callback.
Just be careful and make sure you handle errors with .catch()
. Promise.all()
rejects as soon as one of the promises in the array rejects.
It depends on the tools you can use. I doubt there is a JavaScript too that could do it directly within the browser. It also depends if it's a one-off (always the same key) or whether you need to script it.
If you want to use something like OpenSSL on a unix command line, you can do something as follows. I'm assuming you public.key file contains something like this:
-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAmBAjFv+29CaiQqYZIw4P
J0q5Qz2gS7kbGleS3ai8Xbhu5n8PLomldxbRz0RpdCuxqd1yvaicqpDKe/TT09sR

5xVkSp3kxcNcNb/mePSKQIPafQ1sAmBKPwycA/1I5nLzDVuQa95ZWMn0JkphtFIh
HQIDAQAB
-----END PUBLIC KEY-----
Then, the commands would be:
PUBKEY=`grep -v -- ----- public.key | tr -d '\n'`
Then, you can look into the ASN.1 structure:
echo $PUBKEY | base64 -d | openssl asn1parse -inform DER -i
This should give you something like this:
0:d=0 hl=4 l= 290 cons: SEQUENCE
4:d=1 hl=2 l= 13 cons: SEQUENCE
6:d=2 hl=2 l= 9 prim: OBJECT :rsaEncryption
17:d=2 hl=2 l= 0 prim: NULL
19:d=1 hl=4 l= 271 prim: BIT STRING
The modulus and public exponent are in the last BIT STRING, offset 19, so use -strparse
:
echo $PUBKEY | base64 -d | openssl asn1parse -inform DER -i -strparse 19
This will give you the modulus and the public exponent, in hexadecimal (the two INTEGERs):

4:d=1 hl=4 l= 257 prim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
265:d=1 hl=2 l= 3 prim: INTEGER :010001
That's probably fine if it's always the same key, but this is probably not very convenient to put in a script.
Alternatively (and this might be easier to put into a script),
openssl rsa -pubin -inform PEM -text -noout < public.key
will return this:

It depends on the input format. If it's an X.509 certificate in a keystore, use (RSAPublicKey)cert.getPublicKey()
: this object has two getters for the modulus and the exponent.
If it's in the format as above, you might want to use BouncyCastle and its PEMReader
to read it. I haven't tried the following code, but this would look more or less like this:
PEMReader pemReader = new PEMReader(new FileReader("file.pem"));
Object obj = pemReader.readObject();
pemReader.close();
if (obj instanceof X509Certificate) {
// Just in case your file contains in fact an X.509 certificate,
// useless otherwise.
obj = ((X509Certificate)obj).getPublicKey();
}
if (obj instanceof RSAPublicKey) {
// ... use the getters to get the BigIntegers.
}
(You can use BouncyCastle similarly in C# too.)
If you define custom CSS you must set font-weight: 900;
for some newer Font Awesome library (from version 5). Not setting this font-weight it may show squares.
Use a Comparator
like this:
List<Fruit> fruits= new ArrayList<Fruit>();
Fruit fruit;
for(int i = 0; i < 100; i++)
{
fruit = new Fruit();
fruit.setname(...);
fruits.add(fruit);
}
// Sorting
Collections.sort(fruits, new Comparator<Fruit>() {
@Override
public int compare(Fruit fruit2, Fruit fruit1)
{
return fruit1.fruitName.compareTo(fruit2.fruitName);
}
});
Now your fruits list is sorted based on fruitName
.
In your controller, render the new
action from your create action if validation fails, with an instance variable, @car
populated from the user input (i.e., the params
hash). Then, in your view, add a logic check (either an if block around the form
or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params
values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car
is set.
You can use curl
as is in this thread
For the lazy:
*/5 * * * * curl --request GET 'http://exemple.com/path/check.php?param1=1'
This will be executed every 5 minutes.
Html.CheckBox is doing something weird - if you view source on the resulting page, you'll see there's an <input type="hidden" />
being generated alongside each checkbox, which explains the "true false" values you're seeing for each form element.
Try this, which definitely works on ASP.NET MVC Beta because I've just tried it.
Put this in the view instead of using Html.CheckBox():
<% using (Html.BeginForm("ShowData", "Home")) { %>
<% foreach (var o in ViewData.Model) { %>
<input type="checkbox" name="selectedObjects" value="<%=o.Id%>">
<%= o.Name %>
<%}%>
<input type="submit" value="Submit" />
<%}%>
Your checkboxes are all called selectedObjects
, and the value
of each checkbox is the GUID of the corresponding object.
Then post to the following controller action (or something similar that does something useful instead of Response.Write())
public ActionResult ShowData(Guid[] selectedObjects) {
foreach (Guid guid in selectedObjects) {
Response.Write(guid.ToString());
}
Response.End();
return (new EmptyResult());
}
This example will just write the GUIDs of the boxes you checked; ASP.NET MVC maps the GUID values of the selected checkboxes into the Guid[] selectedObjects
parameter for you, and even parses the strings from the Request.Form collection into instantied GUID objects, which I think is rather nice.
The output went to stderr. Use 2>
to capture that.
$make 2> file
The selected answer didn't solve this issue for me. So for those still scratching their head over this one, I found another solution!
In my Apache settings httpd.conf
(you can find the conf file by running apachectl -V
in your console), enabled the following module:
LoadModule rewrite_module modules/mod_rewrite.so
And now the site works as expected.
I would choose Sequelize because of it's excellent documentation. It's just a honest opinion (I never really used MySQL with Node that much).
I found the similar problem and found the solution and i have blogged about how to upload the file using JSP , In that example i have used the absolute path. Note that if you want to route to some other URL based location you can put a ESB like WSO2 ESB
I had the same problem after changing the namespace from "tempuri" in my Web Service.
You have to update your Service Reference in the project that is consuming the above service, so it can get the latest SOAP definitions.
Or at least that worked for me. :)
I found a way to get the arguments with an equal sign (=)! The answer is especially an addition to @lesmana 's answer (as it is the most complete and explained one here), but it would be too big to write it as a comment. Again, I repeat his message: TL;DR don't try to do this!
I needed a way to treat my argument --xyz-enabled=false
(since the default is true), which we all know by now that this is not a make target and thus not part of $(MAKECMDGOALS)
.
While looking into all variables of make by echoing the $(.VARIABLES)
i got these interesting outputs:
[...] -*-command-variables-*- --xyz-enabled [...]
This allows us to go two ways: either getting all starting with a --
(if that applies to your case), or look into the GNU make specific (probably not intended for us to use) variable -*-command-variables-*-
. ** See footer for additional options ** In my case this variable held:
--xyz-enabled=false
With this variable we can combine it with the already existing solution with $(MAKECMDGOALS)
and thus by defining:
# the other technique to invalidate other targets is still required, see linked post
run:
@echo ./prog $(-*-command-variables-*-) $(filter-out $@,$(MAKECMDGOALS))`
and using it with (explicitly mixing up order of arguments):
make run -- config --xyz-enabled=false over=9000 --foo=bar show isit=alwaysreversed? --help
returned:
./prog isit=alwaysreversed? --foo=bar over=9000 --xyz-enabled=false config show --help
As you can see, we loose the total order of the args. The part with the "assignment"-args seem to have been reversed, the order of the "target"-args are kept. I placed the "assignment"-args in the beginning, hopefully your program doesn't care where the argument is placed.
Update: following make variables look promising as well:
MAKEFLAGS = -- isit=alwaysreverse? --foo=bar over=9000 --xyz-enabled=false
MAKEOVERRIDES = isit=alwaysreverse? --foo=bar over=9000 --xyz-enabled=false
I stopped using DECODE
several years ago because it is non-portable. Also, it is less flexible and less readable than a CASE/WHEN
.
However, there is one neat "trick" you can do with decode because of how it deals with NULL. In decode, NULL is equal to NULL. That can be exploited to tell whether two columns are different as below.
select a, b, decode(a, b, 'true', 'false') as same
from t;
A B SAME
------ ------ -----
1 1 true
1 0 false
1 false
null null true
Or you can use dplyr
's add_rownames
which does the same thing as David's answer:
library(dplyr)
df <- tibble::rownames_to_column(df, "VALUE")
UPDATE (mid-2016): (incorporated to the above)
old function called add_rownames()
has been deprecated and is being replaced by tibble::rownames_to_column()
(same functions, but Hadley refactored dplyr
a bit).
I answered a similar question here
As @Syden said, the mixins will work. Another option is using SASS map-get
like this..
@media (min-width: map-get($grid-breakpoints, sm)){
.something {
padding: 10px;
}
}
@media (min-width: map-get($grid-breakpoints, md)){
.something {
padding: 20px;
}
}

I knew I had this proto'd somewhere :)
Array.prototype.init = function(x,n)
{
if(typeof(n)=='undefined') { n = this.length; }
while (n--) { this[n] = x; }
return this;
}
var a = (new Array(5)).init(0);
var b = [].init(0,4);
Edit: tests
In response to Joshua and others methods I ran my own benchmarking, and I'm seeing completely different results to those reported.
Here's what I tested:
//my original method
Array.prototype.init = function(x,n)
{
if(typeof(n)=='undefined') { n = this.length; }
while (n--) { this[n] = x; }
return this;
}
//now using push which I had previously thought to be slower than direct assignment
Array.prototype.init2 = function(x,n)
{
if(typeof(n)=='undefined') { n = this.length; }
while (n--) { this.push(x); }
return this;
}
//joshua's method
function newFilledArray(len, val) {
var a = [];
while(len--){
a.push(val);
}
return a;
}
//test m1 and m2 with short arrays many times 10K * 10
var a = new Date();
for(var i=0; i<10000; i++)
{
var t1 = [].init(0,10);
}
var A = new Date();
var b = new Date();
for(var i=0; i<10000; i++)
{
var t2 = [].init2(0,10);
}
var B = new Date();
//test m1 and m2 with long array created once 100K
var c = new Date();
var t3 = [].init(0,100000);
var C = new Date();
var d = new Date();
var t4 = [].init2(0,100000);
var D = new Date();
//test m3 with short array many times 10K * 10
var e = new Date();
for(var i=0; i<10000; i++)
{
var t5 = newFilledArray(10,0);
}
var E = new Date();
//test m3 with long array created once 100K
var f = new Date();
var t6 = newFilledArray(100000, 0)
var F = new Date();
Results:
IE7 deltas:
dA=156
dB=359
dC=125
dD=375
dE=468
dF=412
FF3.5 deltas:
dA=6
dB=13
dC=63
dD=8
dE=12
dF=8
So by my reckoning push is indeed slower generally but performs better with longer arrays in FF but worse in IE which just sucks in general (quel surprise).
An executor service can be used to manage multiple threads including status and completion. See http://programmingexamples.wikidot.com/executorservice
for Kotlin, just call
textview.text = string.capitalize()
I see only two options:
I think this may help you , both index and columns of the values.
value you are looking for is not duplicated:
poz=matrix[matrix==minv].dropna(axis=1,how='all').dropna(how='all')
value=poz.iloc[0,0]
index=poz.index.item()
column=poz.columns.item()
you can get its index and column
duplicated:
matrix=pd.DataFrame([[1,1],[1,np.NAN]],index=['q','g'],columns=['f','h'])
matrix
Out[83]:
f h
q 1 1.0
g 1 NaN
poz=matrix[matrix==minv].dropna(axis=1,how='all').dropna(how='all')
index=poz.stack().index.tolist()
index
Out[87]: [('q', 'f'), ('q', 'h'), ('g', 'f')]
you will get a list

If you have a backend server asking for the Basic Auth credentials before the app then this is sufficient, it will re-use that then:
fetch(url, {
credentials: 'include',
}).then(...);
Or if you just want to redefine the behavior of the console (in order to add logs for example) You can do something like that:
// define a new console
var console=(function(oldCons){
return {
log: function(text){
oldCons.log(text);
// Your code
},
info: function (text) {
oldCons.info(text);
// Your code
},
warn: function (text) {
oldCons.warn(text);
// Your code
},
error: function (text) {
oldCons.error(text);
// Your code
}
};
}(window.console));
//Then redefine the old console
window.console = console;

You can also install Git Credential Manager for Windows to save Git passwords in Windows credentials manager instead of _netrc

While let us also note that ampersand #to_proc
magic can work with any class, not just Symbol. Many Rubyists choose to define #to_proc
on Array class:
class Array
def to_proc
proc { |receiver| receiver.send *self }
end
end
# And then...
[ 'Hello', 'Goodbye' ].map &[ :+, ' world!' ]
#=> ["Hello world!", "Goodbye world!"]
Ampersand &
works by sending to_proc
message on its operand, which, in the above code, is of Array class. And since I defined #to_proc
method on Array, the line becomes:
[ 'Hello', 'Goodbye' ].map { |receiver| receiver.send( :+, ' world!' ) }
I guess , you means $_SERVER['PHP_SELF']
. And if so , you really shouldn't use it without sanitizing it first. This leaves you open to XSS attacks.
The if(isset($_POST['submit']))
condition should be above all the HTML output, and should contain a header()
function with a redirect to current page again (only now , with some nice notice that "emails has been sent" .. or something ). For that you will have to use $_SESSION
or $_COOKIE
.
And please. Stop using $_REQUEST
. It too poses a security threat.
a {
display: block;
position: relative;
}
I think that is all you need.
Strings in Python are immutable meaning you cannot replace parts of them.
You can however create a new string that is modified. Mind that this is not semantically equivalent since other references to the old string will not be updated.
You could for instance write a function:
def replace_str_index(text,index=0,replacement=''):
return '%s%s%s'%(text[:index],replacement,text[index+1:])
And then for instance call it with:
new_string = replace_str_index(old_string,middle)
If you do not feed a replacement, the new string will not contain the character you want to remove, you can feed it a string of arbitrary length.
For instance:
replace_str_index('hello?bye',5)
will return 'hellobye'
; and:
replace_str_index('hello?bye',5,'good')
will return 'hellogoodbye'
.
You just need one line:
from django.contrib.auth.decorators import user_passes_test
@user_passes_test(lambda u: u.groups.filter(name='companyGroup').exists())
def you_view():
return HttpResponse("Since you're logged in, you can see this text!")
You can pass the format in to the ToString
method, e.g.:
myFloatVariable.ToString("0.00"); //2dp Number
myFloatVariable.ToString("n2"); // 2dp Number
myFloatVariable.ToString("c2"); // 2dp currency
You can add 1 to each example New = 5; old = 0;
(1+new) - (old+1) / (old +1) 5/ 1 * 100 ==> 500%
You can use %p in C
In C:
printf("%p",p)
In C++:
cout<<"Address of pointer p is: "<<p
Using pure Javascript:
Don't need to pass this
to the SomeDeleteRowFunction()
:
<td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction()"></td>
The onclick function:
function SomeDeleteRowFunction() {
// event.target will be the input element.
var td = event.target.parentNode;
var tr = td.parentNode; // the row to be removed
tr.parentNode.removeChild(tr);
}
You can use anonymous types for this, i.e.:
var pageObject = (from op in db.ObjectPermissions
join pg in db.Pages on op.ObjectPermissionName equals page.PageName
where pg.PageID == page.PageID
select new { pg, op }).SingleOrDefault();
This will make pageObject into an IEnumerable of an anonymous type so AFAIK you won't be able to pass it around to other methods, however if you're simply obtaining data to play with in the method you're currently in it's perfectly fine. You can also name properties in your anonymous type, i.e.:-
var pageObject = (from op in db.ObjectPermissions
join pg in db.Pages on op.ObjectPermissionName equals page.PageName
where pg.PageID == page.PageID
select new
{
PermissionName = pg,
ObjectPermission = op
}).SingleOrDefault();
This will enable you to say:-
if (pageObject.PermissionName.FooBar == "golden goose") Application.Exit();
For example :-)

Update:
Planned in the scope of 3.7 release
https://github.com/microsoft/TypeScript/issues/33352
You can try to write a custom function like that.
The main advantage of the approach is a type-checking and partial intellisense.
export function nullSafe<T,
K0 extends keyof T,
K1 extends keyof T[K0],
K2 extends keyof T[K0][K1],
K3 extends keyof T[K0][K1][K2],
K4 extends keyof T[K0][K1][K2][K3],
K5 extends keyof T[K0][K1][K2][K3][K4]>
(obj: T, k0: K0, k1?: K1, k2?: K2, k3?: K3, k4?: K4, k5?: K5) {
let result: any = obj;
const keysCount = arguments.length - 1;
for (var i = 1; i <= keysCount; i++) {
if (result === null || result === undefined) return result;
result = result[arguments[i]];
}
return result;
}
And usage (supports up to 5 parameters and can be extended):
nullSafe(a, 'b', 'c');
Example on playground.
My take on this for future people watching this:
This could also happen if you're using: <?
instead of <?php
.
use selectionChange in angular 6 and above. example

There's another option not cited here which is included in the GNU Make book by Stallman and McGrath (see http://www.chemie.fu-berlin.de/chemnet/use/info/make/make_7.html). It provides the example:
archive.a: ...
ifneq (,$(findstring t,$(MAKEFLAGS)))
+touch archive.a
+ranlib -t archive.a
else
ranlib archive.a
endif
It involves verifying if a given parameter appears in MAKEFLAGS
. For example .. suppose that you're studying about threads in c++11 and you've divided your study across multiple files (class01
, ... , classNM
) and you want to: compile then all and run individually or compile one at a time and run it if a flag is specified (-r
, for instance). So, you could come up with the following Makefile
:
CXX=clang++-3.5
CXXFLAGS = -Wall -Werror -std=c++11
LDLIBS = -lpthread
SOURCES = class01 class02 class03
%: %.cxx
$(CXX) $(CXXFLAGS) -o [email protected] $^ $(LDLIBS)
ifneq (,$(findstring r, $(MAKEFLAGS)))
./[email protected]
endif
all: $(SOURCES)
.PHONY: clean
clean:
find . -name "*.out" -delete
Having that, you'd:
make -r class02
; make
or make all
;make -r
(suppose that all of them contain some certain kind of assert stuff and you just want to test them all)Try restarting your computer
