It appears that the up-to-date answer to this is to not use filter-branch
directly (at least git itself does not recommend it anymore), and defer that work to an external tool. In particular, git-filter-repo is currently recommended. The author of that tool provides arguments on why using filter-branch
directly can lead to issues.
Most of the multi-line scripts above to remove dir
from the history could be re-written as:
git filter-repo --path dir --invert-paths
The tool is more powerful than just that, apparently. You can apply filters by author, email, refname and more (full manpage here). Furthermore, it is fast. Installation is easy - it is distributed in a variety of formats.
The if
attribute does not exist for <copy>
. It should be applied to the <target>
.
Below is an example of how you can use the depends
attribute of a target and the if
and unless
attributes to control execution of dependent targets. Only one of the two should execute.
<target name="prepare-copy" description="copy file based on condition"
depends="prepare-copy-true, prepare-copy-false">
</target>
<target name="prepare-copy-true" description="copy file based on condition"
if="copy-condition">
<echo>Get file based on condition being true</echo>
<copy file="${some.dir}/true" todir="." />
</target>
<target name="prepare-copy-false" description="copy file based on false condition"
unless="copy-condition">
<echo>Get file based on condition being false</echo>
<copy file="${some.dir}/false" todir="." />
</target>
If you are using ANT 1.8+, then you can use property expansion and it will evaluate the value of the property to determine the boolean value. So, you could use if="${copy-condition}"
instead of if="copy-condition"
.
In ANT 1.7.1 and earlier, you specify the name of the property. If the property is defined and has any value (even an empty string), then it will evaluate to true.
Update your environment variables
Ensure the reference to java/bin is up to date in 'Path'; This may be automatic if you have JAVA_HOME or equivalent set. If JAVA_HOME is set, simply update it to refer to the older JRE installation.
Further reading for any of the topics here: The Definitive Guide to Linux System Calls
I verified these using GNU Assembler (gas) on Linux.
x86-32 aka i386 Linux System Call convention:
In x86-32 parameters for Linux system call are passed using registers. %eax
for syscall_number. %ebx, %ecx, %edx, %esi, %edi, %ebp are used for passing 6 parameters to system calls.
The return value is in %eax
. All other registers (including EFLAGS) are preserved across the int $0x80
.
I took following snippet from the Linux Assembly Tutorial but I'm doubtful about this. If any one can show an example, it would be great.
If there are more than six arguments,
%ebx
must contain the memory location where the list of arguments is stored - but don't worry about this because it's unlikely that you'll use a syscall with more than six arguments.
For an example and a little more reading, refer to http://www.int80h.org/bsdasm/#alternate-calling-convention. Another example of a Hello World for i386 Linux using int 0x80
: Hello, world in assembly language with Linux system calls?
There is a faster way to make 32-bit system calls: using sysenter
. The kernel maps a page of memory into every process (the vDSO), with the user-space side of the sysenter
dance, which has to cooperate with the kernel for it to be able to find the return address. Arg to register mapping is the same as for int $0x80
. You should normally call into the vDSO instead of using sysenter
directly. (See The Definitive Guide to Linux System Calls for info on linking and calling into the vDSO, and for more info on sysenter
, and everything else to do with system calls.)
x86-32 [Free|Open|Net|DragonFly]BSD UNIX System Call convention:
Parameters are passed on the stack. Push the parameters (last parameter pushed first) on to the stack. Then push an additional 32-bit of dummy data (Its not actually dummy data. refer to following link for more info) and then give a system call instruction int $0x80
http://www.int80h.org/bsdasm/#default-calling-convention
(Note: x86-64 Mac OS X is similar but different from Linux. TODO: check what *BSD does)
Refer to section: "A.2 AMD64 Linux Kernel Conventions" of System V Application Binary Interface AMD64 Architecture Processor Supplement. The latest versions of the i386 and x86-64 System V psABIs can be found linked from this page in the ABI maintainer's repo. (See also the x86 tag wiki for up-to-date ABI links and lots of other good stuff about x86 asm.)
Here is the snippet from this section:
- User-level applications use as integer registers for passing the sequence %rdi, %rsi, %rdx, %rcx, %r8 and %r9. The kernel interface uses %rdi, %rsi, %rdx, %r10, %r8 and %r9.
- A system-call is done via the
syscall
instruction. This clobbers %rcx and %r11 as well as the %rax return value, but other registers are preserved.- The number of the syscall has to be passed in register %rax.
- System-calls are limited to six arguments, no argument is passed directly on the stack.
- Returning from the syscall, register %rax contains the result of the system-call. A value in the range between -4095 and -1 indicates an error, it is
-errno
.- Only values of class INTEGER or class MEMORY are passed to the kernel.
Remember this is from the Linux-specific appendix to the ABI, and even for Linux it's informative not normative. (But it is in fact accurate.)
This 32-bit int $0x80
ABI is usable in 64-bit code (but highly not recommended). What happens if you use the 32-bit int 0x80 Linux ABI in 64-bit code? It still truncates its inputs to 32-bit, so it's unsuitable for pointers, and it zeros r8-r11.
x86-32 Function Calling convention:
In x86-32 parameters were passed on stack. Last parameter was pushed first on to the stack until all parameters are done and then call
instruction was executed. This is used for calling C library (libc) functions on Linux from assembly.
Modern versions of the i386 System V ABI (used on Linux) require 16-byte alignment of %esp
before a call
, like the x86-64 System V ABI has always required. Callees are allowed to assume that and use SSE 16-byte loads/stores that fault on unaligned. But historically, Linux only required 4-byte stack alignment, so it took extra work to reserve naturally-aligned space even for an 8-byte double
or something.
Some other modern 32-bit systems still don't require more than 4 byte stack alignment.
x86-64 System V passes args in registers, which is more efficient than i386 System V's stack args convention. It avoids the latency and extra instructions of storing args to memory (cache) and then loading them back again in the callee. This works well because there are more registers available, and is better for modern high-performance CPUs where latency and out-of-order execution matter. (The i386 ABI is very old).
In this new mechanism: First the parameters are divided into classes. The class of each parameter determines the manner in which it is passed to the called function.
For complete information refer to : "3.2 Function Calling Sequence" of System V Application Binary Interface AMD64 Architecture Processor Supplement which reads, in part:
Once arguments are classified, the registers get assigned (in left-to-right order) for passing as follows:
- If the class is MEMORY, pass the argument on the stack.
- If the class is INTEGER, the next available register of the sequence %rdi, %rsi, %rdx, %rcx, %r8 and %r9 is used
So %rdi, %rsi, %rdx, %rcx, %r8 and %r9
are the registers in order used to pass integer/pointer (i.e. INTEGER class) parameters to any libc function from assembly. %rdi is used for the first INTEGER parameter. %rsi for 2nd, %rdx for 3rd and so on. Then call
instruction should be given. The stack (%rsp
) must be 16B-aligned when call
executes.
If there are more than 6 INTEGER parameters, the 7th INTEGER parameter and later are passed on the stack. (Caller pops, same as x86-32.)
The first 8 floating point args are passed in %xmm0-7, later on the stack. There are no call-preserved vector registers. (A function with a mix of FP and integer arguments can have more than 8 total register arguments.)
Variadic functions (like printf
) always need %al
= the number of FP register args.
There are rules for when to pack structs into registers (rdx:rax
on return) vs. in memory. See the ABI for details, and check compiler output to make sure your code agrees with compilers about how something should be passed/returned.
Note that the Windows x64 function calling convention has multiple significant differences from x86-64 System V, like shadow space that must be reserved by the caller (instead of a red-zone), and call-preserved xmm6-xmm15. And very different rules for which arg goes in which register.
You can use the static/class constructor to initialize your dictionary:
public static class ErrorCode
{
public const IDictionary<string, string> ErrorCodeDic;
public static ErrorCode()
{
ErrorCodeDic = new Dictionary<string, string>()
{ {"1", "User name or password problem"} };
}
}

If you'd like to use +
for concatenation of anything which has an output operator, you can provide a template version of operator+
:
template <typename L, typename R> std::string operator+(L left, R right) {
std::ostringstream os;
os << left << right;
return os.str();
}
Then you can write your concatenations in a straightforward way:
std::string foo("the answer is ");
int i = 42;
std::string bar(foo + i);
std::cout << bar << std::endl;
Output:
the answer is 42
This isn't the most efficient way, but you don't need the most efficient way unless you're doing a lot of concatenation inside a loop.

You were on the right track with your "ng-keydown" attribute on the input, but you missed a simple step. Just because you put the ng-keydown attribute there, doesn't mean angular knows what to do with it. That's where "directives" come into play. You used the attribute correctly, but you now need to write a directive that will tell angular what to do when it sees that attribute on an html element.
The following is an example of how you would do that. We'll rename the directive from ng-keydown
to on-keydown
(to avoid breaking the "best practice" found here):
var mod = angular.module('mydirectives');
mod.directive('onKeydown', function() {
return {
restrict: 'A',
link: function(scope, elem, attrs) {
// this next line will convert the string
// function name into an actual function
var functionToCall = scope.$eval(attrs.ngKeydown);
elem.on('keydown', function(e){
// on the keydown event, call my function
// and pass it the keycode of the key
// that was pressed
// ex: if ENTER was pressed, e.which == 13
functionToCall(e.which);
});
}
};
});
The directive simple tells angular that when it sees an HTML attribute called "ng-keydown", it should listen to the element that has that attribute and call whatever function is passed to it. In the html you would have the following:
<input type="text" on-keydown="onKeydown">
And then in your controller (just like you already had), you would add a function to your controller's scope that is called "onKeydown", like so:
$scope.onKeydown = function(keycode){
// do something with the keycode
}
Hopefully that helps either you or someone else who wants to know
It is possible and is deceptively easy:
bin\Debug
folder below the project file (.csproj).app.publish
folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).
As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.
It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.

*border-left-color: #ffffff;
}
Working example: http://bootply.com/74926
UPDATE
If you don't need the exact look of a tab (bordered appropriately on the left or right as each tab is activated), you can simple use nav-stacked
, along with Bootstrap col-*
to float the tabs to the left or right...
nav-stacked
demo: http://codeply.com/go/rv3Cvr0lZ4
<ul class="nav nav-pills nav-stacked col-md-3">
<li><a href="#a" data-toggle="tab">1</a></li>
<li><a href="#b" data-toggle="tab">2</a></li>
<li><a href="#c" data-toggle="tab">3</a></li>
</ul>
For beginners, the accepted answer is correct, but a little terse if you're not that familiar with either VSC or Regex.
So, in case this is your first contact with either:
To find and modify text,
In the "Find" step, you can use regex with "capturing groups," e.g. I want to find (group1) and (group2)
, using parentheses. This would find the same text as I want to find group1 and group2
, but with the difference that you can then reference group1
and group2
in the next step:
In the "Replace" step, you can refer to the capturing groups via $1
, $2
etc, so you could change the sentence to I found $1 and $2 having a picnic
, which would output I found group1 and group2 having a picnic.
Notes:
Instead of just a string, anything inside or outside the ()
can be a regular expression.
$0
refers to the whole match
[[UIDevice currentDevice] uniqueIdentifier]
Returns the Unique ID of your iPhone.
EDIT:
-[UIDevice uniqueIdentifier]
is now deprecated and apps are being rejected from the App Store for using it. The method below is now the preferred approach.
If you need to create several UUID, just use this method (with ARC):
+ (NSString *)GetUUID
{
CFUUIDRef theUUID = CFUUIDCreate(NULL);
CFStringRef string = CFUUIDCreateString(NULL, theUUID);
CFRelease(theUUID);
return (__bridge NSString *)string;
}
EDIT: Jan, 29 2014: If you're targeting iOS 6 or later, you can now use the much simpler method:
NSString *UUID = [[NSUUID UUID] UUIDString];
I'm doing the same thing using invalidateViews() and that works for me. If you want it to invalidate immediately you could try calling postInvalidate after calling invalidateViews.
Create a simple project with pom.xml only. Add your dependency and run:
mvn dependency:tree
Unfortunately dependency mojo must use pom.xml or you get following error:
Cannot execute mojo: tree. It requires a project with an existing pom.xml, but the build is not using one.
Dependencies are described In pom.xml of your artifact. Find it using maven infrastructure.
Go to https://search.maven.org/ and enter your groupId and artifactId.
Or you can go to https://repo1.maven.org/maven2/ and navigate first using plugins groupId, later using artifactId and finally using its version.
For example see org.springframework:spring-core
Part of dependency artifact is a pom.xml. That specifies it's dependency. And you can execute mvn dependency:tree on this pom.
df = pd.DataFrame({'movie': ['thg', 'thg', 'mol', 'mol', 'lob', 'lob'],'rating': [3., 4., 5., np.nan, np.nan, np.nan],'name': ['John','James', np.nan, np.nan, np.nan,np.nan]})
for col in df.columns:
df = df[~pd.isnull(df[col])]
My real world example to insert all german postcodes into an empty table (to add town names later):
// obtain column template
$stmt = $db->prepare('SHOW COLUMNS FROM towns');
$stmt->execute();
$columns = array_fill_keys(array_values($stmt->fetchAll(PDO::FETCH_COLUMN)), null);
// multiple INSERT
$postcode = '01000';// smallest german postcode
while ($postcode <= 99999) {// highest german postcode
$values = array();
while ($postcode <= 99999) {
// reset row
$row = $columns;
// now fill our row with data
$row['postcode'] = sprintf('%05d', $postcode);
// build INSERT array
foreach ($row as $value) {
$values[] = $value;
}
$postcode++;
// avoid memory kill
if (!($postcode % 10000)) {
break;
}
}
// build query
$count_columns = count($columns);
$placeholder = ',(' . substr(str_repeat(',?', $count_columns), 1) . ')';//,(?,?,?)
$placeholder_group = substr(str_repeat($placeholder, count($values) / $count_columns), 1);//(?,?,?),(?,?,?)...
$into_columns = implode(',', array_keys($columns));//col1,col2,col3
// this part is optional:
$on_duplicate = array();
foreach ($columns as $column => $row) {
$on_duplicate[] = $column;
$on_duplicate[] = $column;
}
$on_duplicate = ' ON DUPLICATE KEY UPDATE' . vsprintf(substr(str_repeat(', %s = VALUES(%s)', $count_columns), 1), $on_duplicate);
// execute query
$stmt = $db->prepare('INSERT INTO towns (' . $into_columns . ') VALUES' . $placeholder_group . $on_duplicate);//INSERT INTO towns (col1,col2,col3) VALUES(?,?,?),(?,?,?)... {ON DUPLICATE...}
$stmt->execute($values);
}
As you can see its fully flexible. You don't need to check the amount of columns or check on which position your column is. You only need to set the insert data:
$row['postcode'] = sprintf('%05d', $postcode);
I'm proud of some of the query string constructors as they work without heavy array-functions like array_merge. Especially vsprintf() was a good find.
Finally I needed to add 2x while() to avoid exceeding the memory limit. This depends on your memory limit but at all its a good general solution to avoid problems (and having 10 queries is still much better than 10.000).
Let us assume the database character set is UTF-8, which is the recommended setting in recent versions of Oracle. In this case, some characters take more than 1 byte to store in the database.
If you define the field as VARCHAR2(11 BYTE)
, Oracle can use up to 11 bytes for storage, but you may not actually be able to store 11 characters in the field, because some of them take more than one byte to store, e.g. non-English characters.
By defining the field as VARCHAR2(11 CHAR)
you tell Oracle it can use enough space to store 11 characters, no matter how many bytes it takes to store each one. A single character may require up to 4 bytes.
Use expression(delta)
where 'delta' for lowercase d
and 'Delta' to get capital ?
.
Here's full list of Greek characters:
? a alpha
? ß beta
G ? gamma

? e epsilon
? ? zeta
? ? eta
T ? theta
? ? iota
? ? kappa
? ? lambda
? µ mu
? ? nu
? ? xi
? ? omicron
? p pi
? ? rho
S s sigma
? t tau
? ? upsilon
F f phi
? ? chi
? ? psi
O ? omega
EDIT: Copied from comments, when using in conjunction with other words use like: expression(Delta*"price")
You need to use v-bind:
or its alias :
. For example,
<a v-bind:href="'/job/'+ r.id">
or
<a :href="'/job/' + r.id">
You can simple put like this
public sealed class Employee
{
public int Id { get; set; } = 101;
}
Possibly an easier way?
Let's say justPrices is mixed up in terms of value, so you don't know where the smallest value is.
justPrices[0] = 4.5
justPrices[1] = 9.9
justPrices[2] = 1.5
Use sort.
justPrices.sort();
It would then put them in order for you. (Can also be done alphabetically.) The array then would be put in ascending order.
justPrices[0] = 1.5
justPrices[1] = 4.5
justPrices[2] = 9.9
You can then easily grab by the first index.
justPrices[0]
I find this is a bit more useful than what's proposed above because what if you need the lowest 3 numbers as an example? You can also switch which order they're arranged, more info at http://www.w3schools.com/jsref/jsref_sort.asp
$(':focus')[0]
will give you the actual element.
$(':focus')
will give you an array of elements, usually only one element is focused at a time so this is only better if you somehow have multiple elements focused.
->getSingleScalarResult() will return a single value, instead of an array.
You can create multi-line strings by enclosing them in triple quotes. So you can store your HTML in a string and pass that string to write()
:
html_str = """
<table border=1>
<tr>
<th>Number</th>
<th>Square</th>
</tr>
<indent>
<% for i in range(10): %>
<tr>
<td><%= i %></td>
<td><%= i**2 %></td>
</tr>
</indent>
</table>
"""
Html_file= open("filename","w")
Html_file.write(html_str)
Html_file.close()
When installing laravel on Ubuntu 18.04, be default PHP 7.3.0RC3 install selected, but laravel and symfony will not install properly complaining about missin php-xml and php-zip, even though they are installed. You need to switch to php 7.1, using the instructions above or,

Here the defination of Rendersection from MSDN
In layout pages, renders the content of a named section.MSDN
In _layout.cs page put
@RenderSection("Bottom",false)
Here render the content of bootom section and specifies false
boolean property to specify whether the section is required or not.
@section Bottom{
This message form bottom.
}
That meaning if you want to bottom section in all pages, then you must use false as the second parameter at Rendersection method.

I've been using this trick for several years and it works perfectly without any problem for checked/unchecked checkbox status while using with PHP and Database.
HTML Code: (for Add Page)
<input name="status" type="checkbox" value="1" checked>
Hint: remove "checkbox" if you want to show it as unchecked by default
HTML Code: (for Edit Page)
<input name="status" type="checkbox" value="1"
<?php if ($row['status'] == 1) { echo "checked='checked'"; } ?>>
PHP Code: (use for Add/Edit pages)
$status = $_POST['status'];
if ($status == 1) {
$status = 1;
} else {
$status = 0;
}
Hint: There will always be empty value unless user checked it. So, we already have PHP code to catch it else keep the value to 0. Then, simply use the $status variable for database.
PostgreSQL has a guide on how to best populate a database initially, and they suggest using the COPY command for bulk loading rows. The guide has some other good tips on how to speed up the process, like removing indexes and foreign keys before loading the data (and adding them back afterwards).

Add these lines in your .htaccess file and it will work for all browsers. Works for me.
AddType video/ogg .ogv

AddType video/webm .webm
If you dun have .htaccess file in your site then create new one :) its obvious i guess.
There is nothing stopping you from packing the list into a delimited string and then unpacking it once you get the string from the config. If you did it this way your config section would look like:
[Section 3]
barList=item1,item2
It's not pretty but it's functional for most simple lists.
For questions on simple string manipulation the dir
built-in function comes in handy. It gives you, among others, a list of methods of the argument, e.g., dir(s)

The indexes capable of placing a unique key constraint on a table are PRIMARY
and UNIQUE
indexes.
To remove the unique key constraint on a column but keep the index, you could remove and recreate the index with type INDEX
.
Note that it is a good idea for all tables to have an index marked PRIMARY
.
EASY solution for Mac Excel 2008: I struggled with this soo many times, but here was my easy fix: Open the .csv file in Textwrangler which should open your UTF-8 chars correctly. Now in the bottom status bar change the file format from "Unicode (UTF-8)" to "Western (ISO Latin 1)" and save the file. Now go to your Mac Excel 2008 and select File > Import > Select csv > Find your file > in File origin select "Windows (ANSI)" and voila the UTF-8 chars are showing correctly. At least it does for me...
You can also Make use of the Following if you want to Cast and Round as well. That may help you or someone else.

in sqlite, there is a table called sqlite_sequence, this table contains the table name and it's last id number (if the id is auto incremented).
So, to get the last row in a table just put :
Select * from TABLENAME where id=(SELECT * from sqlite_sequence where name ='TABLENAME')
Please make sure your $row[1] , $row[2]
contains correct value, we do assume here that 1 = Name , and 2 here is your Address field
?
Assuming you have correctly fetched your records from your Records.php, You can do something like this:
$(document).ready(function()
{
$('#getRecords').click(function()
{
var response = '';
$.ajax({ type: 'POST',
url: "Records.php",
async: false,
success : function(text){
$('#table1').html(text);
}
});
});
}
In your HTML
<table id="table1">
//Let jQuery AJAX Change This Text
</table>
<button id='getRecords'>Get Records</button>
A little note:

Your problem may be solved if you give your div
a fixed width, as follows:
div#thing {
position: absolute;
top: 0px;
z-index: 2;
width:400px;
margin-left:-200px;
left:50%;
}
Escape the quotes with backslashes:
printf("She said \"time flies like an arrow, but fruit flies like a banana\".");
There are special escape characters that you can use in string literals, and these are denoted with a leading backslash.
Use following cursor to disable all constraint.. And alter query for enable constraints...

If you don't want to edit the bootstrap CSS or all of the above doesn't help you at all (like in my case), there's an easy fix to get the video running in a modal on Firefox.
You just need to remove the "fade" class from the modal and as it opens the "in" class, too:
$('#myModal').on('shown.bs.modal', function () {
$('#myModal').removeClass('in');
});
A few more points (Reference: Java Concurrency in Practice)
When all non-daemon threads finish, the JVM halts, and any remaining daemon threads are abandoned:
Due to this reason daemon threads should be used sparingly, and it is dangerous to use them for tasks that might perform any sort of I/O.
api.com/users?id=id1,id2,id3,id4,id5
api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5
IMO, above calls does not looks RESTful, however these are quick and efficient workaround (y). But length of the URL is limited by webserver, eg tomcat.
RESTful attempt:
POST http://example.com/api/batchtask
[
{
method : "GET",
headers : [..],
url : "/users/id1"
},
{
method : "GET",
headers : [..],
url : "/users/id2"
}
]
Server will reply URI of newly created batchtask resource.
201 Created
Location: "http://example.com/api/batchtask/1254"
Now client can fetch batch response or task progress by polling
GET http://example.com/api/batchtask/1254
This is how others attempted to solve this issue:
You only need <script></script>
Tag that's it. <script type="text/javascript"></script>
is not a valid HTML tag, so for best SEO practice use <script></script>
This is an old question and its been answered but I thought I'd put the --binary-files=text option here for anyone who wants to use it. The -I option ignores the binary file but if you want the grep to treat the binary file as a text file use --binary-files=text like so:
bash$ grep -i reset mediaLog*
Binary file mediaLog_dc1.txt matches
bash$ grep --binary-files=text -i reset mediaLog*
mediaLog_dc1.txt:2016-06-29 15:46:02,470 - Media [uploadChunk ,315] - ERROR - ('Connection aborted.', error(104, 'Connection reset by peer'))
mediaLog_dc1.txt:ConnectionError: ('Connection aborted.', error(104, 'Connection reset by peer'))
bash$
Here is another way not depending on a library but using a regex.
You can use this single line:
text.matches("\\A\\p{ASCII}*\\z")
Whole example program:
public class Main {
public static void main(String[] args) {
char nonAscii = 0x00FF;
String asciiText = "Hello";
String nonAsciiText = "Buy: " + nonAscii;
System.out.println(asciiText.matches("\\A\\p{ASCII}*\\z"));
System.out.println(nonAsciiText.matches("\\A\\p{ASCII}*\\z"));
}
}
$(selector).filter(function(){return this.value==yourval}).remove();
You probably haven't installed GLUT:
Source: http://cacs.usc.edu/education/cs596/OGL_Setup.pdf
EDIT:
The quickest way is to download the latest header, and compiled DLLs for it, place it in your system32 folder or reference it in your project. Version 3.7 (latest as of this post) is here: http://www.opengl.org/resources/libraries/glut/glutdlls37beta.zip
Folder references:
glut.h: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\GL\'
glut32.lib: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib\'
glut32.dll: 'C:\Windows\System32\'
For 64-bit machines, you will want to do this.
glut32.dll: 'C:\Windows\SysWOW64\'
Same pattern applies to freeglut and GLEW files with the header files in the GL folder, lib in the lib folder, and dll in the System32 (and SysWOW64) folder.
1. Under Visual C++, select Empty Project.
2. Go to Project -> Properties. Select Linker -> Input then add the following to the Additional Dependencies field:
opengl32.lib
glu32.lib
glut32.lib
You want DateTime.DaysInMonth
:
int days = DateTime.DaysInMonth(year, month);
Obviously it varies by year, as sometimes February has 28 days and sometimes 29. You could always pick a particular year (leap or not) if you want to "fix" it to one value or other.
Above .net core 2.2 the method Main support args with WebHost.CreateDefaultBuilder(args)
public class Program

{
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)

}
You can build your project and go to bin
run command like this
dotnet <yours>.dll --urls=http://localhost:5001
or with multi-urls
dotnet <yours>.dll --urls="http://localhost:5001,https://localhost:5002"

MongoVUE looks promising.
That would be the item property: http://msdn.microsoft.com/en-us/library/0ebtbkkc.aspx
Maybe something like this would work:
public T Item[int index, int y]
{
//Then do whatever you need to return/set here.
get; set;
}
I recently answered a similar question here. Applying the same approach to your problem would yield following solution:
list.sort(
p2Ord(stringOrd, stringOrd).comap(new F<String, P2<String, String>>() {
public P2<String, String> f(String s) {
return p(s.toLowerCase(), s);
}
})
);
I know this question has been answered but the answers i found here didn't work for my scenario ( or for Windows ).
I am using windows 10 laptop with PHP 7.2 in Xampp v3.2.4.
$command = 'php Cron.php send_email "'. $id .'"';
if ( substr(php_uname(), 0, 7) == "Windows" )
{
//windows
pclose(popen("start /B " . $command . " 1> temp/update_log 2>&1 &", "r"));
}
else
{
//linux
shell_exec( $command . " > /dev/null 2>&1 &" );
}
This worked perfectly for me.
I hope it will help someone with windows. Cheers.
The excellent library Type::Tiny provides an framework with which to build type-checking into your Perl code. What I show here is only the thinnest tip of the iceberg and is using Type::Tiny in the most simplistic and manual way.
Be sure to check out the Type::Tiny::Manual for more information.
use Types::Common::String qw< NonEmptyStr >;
if ( NonEmptyStr->check($name) ) {
# Do something here.
}
NonEmptyStr->($name); # Throw an exception if validation fails
As one person may have already suggested,
I passed the ISO 8601 date string directly to moment like so...
`moment.utc('2019-11-03T05:00:00.000Z').format('MM/DD/YYYY')`
or
`moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')`
either of these solutions will give you the same result.
`console.log(moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')) // 11/3/2019`
Running the risk of getting another Necromancer badge, I would like to add one very good use for uintptr_t (or even intptr_t) and that is writing testable embedded code. I write mostly embedded code targeted at various arm and currently tensilica processors. These have various native bus width and the tensilica is actually a Harvard architecture with separate code and data buses that can be different widths. I use a test driven development style for much of my code which means I do unit tests for all the code units I write. Unit testing on actual target hardware is a hassle so I typically write everything on an Intel based PC either in Windows or Linux using Ceedling and GCC. That being said, a lot of embedded code involves bit twiddling and address manipulations. Most of my Intel machines are 64 bit. So if you are going to test address manipulation code you need a generalized object to do math on. Thus the uintptr_t give you a machine independent way of debugging your code before you try deploying to target hardware. Another issue is for the some machines or even memory models on some compilers, function pointers and data pointers are different widths. On those machines the compiler may not even allow casting between the two classes, but uintptr_t should be able to hold either. -- Edit -- Was pointed out by @chux, this is not part of the standard and functions are not objects in C. However it usually works and since many people don't even know about these types I usually leave a comment explaining the trickery. Other searches in SO on uintptr_t will provide further explanation. Also we do things in unit testing that we would never do in production because breaking things is good.
I can't think of another way to compare values, but if you use the element of the set as the key, you can set the value to anything other than nil. Then you get fast lookups without having to search the entire table.
If you want to keep your application opened, you have to do something in order to keep its process alive. The below example is the simplest one, to be put at the end of your program:
while (true) ;
However, it'll cause the CPU to overload, as it's therefore forced to iterate infinitely.
At this point, you can opt to use System.Windows.Forms.Application
class (but it requires you to add System.Windows.Forms
reference):
Application.Run();
This doesn't leak CPU and works successfully.
In order to avoid to add System.Windows.Forms
reference, you can use a simple trick, the so-called spin waiting, importing System.Threading
:
SpinWait.SpinUntil(() => false);
This also works perfectly, and it basically consists of a while
loop with a negated condition that is returned by the above lambda method. Why isn't this overloading CPU? You can look at the source code here; anyway, it basically waits some CPU cycle before iterating over.
You can also create a message looper, which peeks the pending messages from the system and processes each of them before passing to the next iteration, as follows:
[DebuggerHidden, DebuggerStepperBoundary, DebuggerNonUserCode, DllImport("user32.dll", EntryPoint = "PeekMessage")]
public static extern int PeekMessage(out NativeMessage lpMsg, IntPtr hWnd, int wMsgFilterMin, int wMsgFilterMax, int wRemoveMsg);
[DebuggerHidden, DebuggerStepperBoundary, DebuggerNonUserCode, DllImport("user32.dll", EntryPoint = "GetMessage")]
public static extern int GetMessage(out NativeMessage lpMsg, IntPtr hWnd, int wMsgFilterMin, int wMsgFilterMax);
[DebuggerHidden, DebuggerStepperBoundary, DebuggerNonUserCode, DllImport("user32.dll", EntryPoint = "TranslateMessage")]
public static extern int TranslateMessage(ref NativeMessage lpMsg);
[DebuggerHidden, DebuggerStepperBoundary, DebuggerNonUserCode, DllImport("user32.dll", EntryPoint = "DispatchMessage")]
public static extern int DispatchMessage(ref NativeMessage lpMsg);
[DebuggerHidden, DebuggerStepperBoundary, DebuggerNonUserCode]
public static bool ProcessMessageOnce()
{
NativeMessage message = new NativeMessage();
if (!IsMessagePending(out message))
return true;
if (GetMessage(out message, IntPtr.Zero, 0, 0) == -1)
return true;
Message frameworkMessage = new Message()
{
HWnd = message.handle,
LParam = message.lParam,
WParam = message.wParam,
Msg = (int)message.msg
};
if (Application.FilterMessage(ref frameworkMessage))
return true;
TranslateMessage(ref message);
DispatchMessage(ref message);
return false;
}
Then, you can loop safely by doing something like this:
while (true)
ProcessMessageOnce();
The request is printed in a request.txt with details
$ch = curl_init();
$f = fopen('request.txt', 'w');
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_FOLLOWLOCATION => 1,
CURLOPT_VERBOSE => 1,
CURLOPT_STDERR => $f,
));
$response = curl_exec($ch);
fclose($f);
curl_close($ch);
You can also use curl_getinfo() function.
A list comprehension is your best bet for the most Pythonic (and fastest) way to do this:
[int(i.days) for i in (df.B - df.A)]
If your columns aren't in datetime format. The shorter syntax would be: df.A = pd.to_datetime(df.A)
In Java terms, there's one more: web container (or more strictly, servlet container). It's, say, in between web server and application server.
A web container in Java terms is an application server that basically only implements the JSP/Servlet part of Java EE and lacks several core parts of Java EE, such as EJB support. An example is Apache Tomcat.
You need to use ContextCompat.getColor(), which is part of the Support V4 Library (so it will work for all the previous API).
ContextCompat.getColor(context, R.color.my_color)
As specified in the documentation, "Starting in M, the returned color will be styled for the specified Context's theme". SO no need to worry about it.
You can add the Support V4 library by adding the following to the dependencies array inside your app build.gradle:
compile 'com.android.support:support-v4:23.0.1'
Try this:
<?php
$servername = "localhost";
$database = "database";
$username = "user";
$password = "password";
// Create connection
$conn = new mysqli($servername, $username, $password, $database);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
I assume I have import datetime
before running each of the lines of code below
datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')
prints "01/25/13"
.
If you can't live with the leading zero, try this:
dt = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print '{0}/{1}/{2:02}'.format(dt.month, dt.day, dt.year % 100)
This prints "1/25/13"
.
EDIT: This may not work on every platform:
datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')
To give a bit more specific answer. HTML5 allows you to get the geo coordinates, and it does a pretty decent job. Overall the browser support for geolocation is pretty good, all major browsers except ie7 and ie8 (and opera mini). IE9 does the job but is the worst performer. Checkout caniuse.com:
http://caniuse.com/#search=geol
Also you need the approval of your user to access their location, so make sure you check for this and give some decent instructions in case it's turned off. Especially for Iphone turning permissions on for Safari is a bit cumbersome.
instead of print $image;
you should go for print "<img src=<?$image;?>>"
and note that $image should contain the path of your image.
So, If you are only storing the name of your image in database then instead of that you have to store the full path of your image in the database like /root/user/Documents/image.jpeg.
foreach ($tmpArray as $innerArray) {
// Check type
if (is_array($innerArray)){
// Scan through inner loop
foreach ($innerArray as $value) {

}
}else{
// one, two, three
echo $innerArray;
}
}
Java has mainly three sub categories :
where core java is the first and basic step of all to start or learn java from beginning.

This is the jQuery method. Looks like overkill but it calculates the offset.

I used all the above answers and it was giving me errors so I tried
adb shell monkey -p com.yourpackage.name -c android.intent.category.LAUNCHER 1
and it worked. One advantage is you dont have to specify your launcher activity if you use this command.
The number of spaces to use for formatting is taken from a different location. I'm using version 1.0 and this is what I've done to fix it (I'm assuming your using spaces instead of tabs):
At the bottom of the editor on the right hand click "Spaces: #":
Then a menu will appear up top. Select "Indent Using Spaces":
Finally you can select by how many spaces you want your files to be indented.
The next time you format a file you should be able to get the spacing you configured.
Did you check the Project settings? I had this problem and I had the Start URL going to a different port than my server specific port. It took me too long to figure out...
Your null pointer exception seems to be on this line:
String url = intent.getExtras().getString("userurl");
because intent.getExtras()
returns null when the intent doesn't have any extras.
You have to realize that this piece of code:
Intent Main = new Intent(this, ToClass.class);
Main.putExtra("userurl", url);
startActivity(Main);
doesn't start the activity you wrote in Main.java, it will attempt to start an activity called ToClass
and if that doesn't exist, your app crashes.
Also, there is no such thing as "android.intent.action.start"
so the manifest should look more like:
<activity android:name=".start" android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name= ".Main">
</activity>
I hope this fixes some of the issues you are encountering but I strongly suggest you check out some "getting started" tutorials for android development and build up from there.

The alternative and easier solution that i also use is to create custom marker layout and convert it into a bitmap.
view_custom_marker.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/custom_marker_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/marker_mask">
<ImageView
android:id="@+id/profile_image"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_gravity="center_horizontal"
android:contentDescription="@null"
android:src="@drawable/avatar" />
</FrameLayout>
Convert this view into bitmap by using the code below
private Bitmap getMarkerBitmapFromView(@DrawableRes int resId) {
View customMarkerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.view_custom_marker, null);
ImageView markerImageView = (ImageView) customMarkerView.findViewById(R.id.profile_image);
markerImageView.setImageResource(resId);
customMarkerView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
customMarkerView.layout(0, 0, customMarkerView.getMeasuredWidth(), customMarkerView.getMeasuredHeight());
customMarkerView.buildDrawingCache();
Bitmap returnedBitmap = Bitmap.createBitmap(customMarkerView.getMeasuredWidth(), customMarkerView.getMeasuredHeight(),
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(returnedBitmap);
canvas.drawColor(Color.WHITE, PorterDuff.Mode.SRC_IN);
Drawable drawable = customMarkerView.getBackground();
if (drawable != null)
drawable.draw(canvas);
customMarkerView.draw(canvas);
return returnedBitmap;
}
Add your custom marker in on Map ready callback.
@Override
public void onMapReady(GoogleMap googleMap) {
Log.d(TAG, "onMapReady() called with");
mGoogleMap = googleMap;
MapsInitializer.initialize(this);
addCustomMarker();
}
private void addCustomMarker() {
Log.d(TAG, "addCustomMarker()");
if (mGoogleMap == null) {
return;
}
// adding a marker on map with image from drawable
mGoogleMap.addMarker(new MarkerOptions()
.position(mDummyLatLng)
.icon(BitmapDescriptorFactory.fromBitmap(getMarkerBitmapFromView(R.drawable.avatar))));
}

Nvm. For anyone else having this problem you need to reboot your mac and press ?+R when booting up. Then go into Utilities > Terminal and type the following commands:
csrutil disable
reboot
This is a result of System Integrity Protection. More info here.
EDIT
If you know what you are doing and are used to running Linux, you should use the above solution as many of the SIP restrictions are a complete pain in the ass.
However, if you are a tinkerer/noob/"poweruser" and don't know what you are doing, this can be very dangerous and you are better off using the answer below.
Yes! Any class in Java can have multiple main methods. It's called Overloading (Overloaded methods are methods with same name but with different signatures) but there should only be one main method with parameters like this :- (String[] args) or (String args[])
For example :-public class E {
public static void main(String args){
System.out.println("Print A");
}
public static void main(String [] args){
System.out.println("Print B");
}
public static void main(int garbage){
System.out.println("Print C");
}
public static void main(int i){
System.out.println("Print D")
}
}
The output of the above program will be "Print B" as only that main method contains the correct method signature identified by the Javac compiler and it compiles that only and leaves the rest.
server {
server_name example.com;
root /path/to/root;
location / {
# bla bla
}
location /demo {
alias /path/to/root/production/folder/here;
}
}
If you need to use try_files
inside /demo
you'll need to replace alias
with a root
and do a rewrite because of the bug explained here
This is so many worlds of bad, because your question implies that you probably have gaping SQL injection holes in your application.
You should be using parameterized statements. For Java, use PreparedStatement
with placeholders. You say you don't want to use parameterised statements, but you don't explain why, and frankly it has to be a very good reason not to use them because they're the simplest, safest way to fix the problem you are trying to solve.
See Preventing SQL Injection in Java. Don't be Bobby's next victim.
There is no public function in PgJDBC for string quoting and escaping. That's partly because it might make it seem like a good idea.
There are built-in quoting functions quote_literal
and quote_ident
in PostgreSQL, but they are for PL/PgSQL
functions that use EXECUTE
. These days quote_literal
is mostly obsoleted by EXECUTE ... USING
, which is the parameterised version, because it's safer and easier. You cannot use them for the purpose you explain here, because they're server-side functions.
Imagine what happens if you get the value ');DROP SCHEMA public;--
from a malicious user. You'd produce:
insert into test values (1,'');DROP SCHEMA public;--');
which breaks down to two statements and a comment that gets ignored:
insert into test values (1,'');
DROP SCHEMA public;
--');
Whoops, there goes your database.
Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.
ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.
The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).
A better option
Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE
). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses
(and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.
This really belongs with @Ramnath's answer but I can't comment as I don't have enough reputation yet. You can also use the arrange
function from the dplyr
package in the same way as the plyr
package.
library(dplyr)
arrange(DF, ID, desc(num))
This isn't quite what you're looking for, but I've found it useful in similar circumstances.
I recently added the following to my $HOME/.bashrc
(something similar should be possible with shells other than bash):
if [ -f $HOME/.add-screen-to-history ] ; then
history -s 'screen -dr'
fi
I keep a screen
session running on one particular machine, and I've had problems with ssh
connections to that machine being dropped, requiring me to re-run screen -dr
every time I reconnect.
With that addition, and after creating that (empty) file in my home directory, I automatically have the screen -dr
command in my history when my shell starts. After reconnecting, I can just type Control-P Enter and I'm back in my screen session -- or I can ignore it. It's flexible, but not quite automatic, and in your case it's easier than typing tmux list-sessions
.
You might want to make the history -s
command unconditional.
This does require updating your $HOME/.bashrc
on each of the target systems, which might or might not make it unsuitable for your purposes.

To add global include path use custom command for qmake in Projects/Build/Build Steps section in "Additional arguments" like this:
"QT+=your_qt_modules" "DEFINES+=your_defines"
I think that you can use any command from *.pro files in that way.
Download the font ttf/other format files, then simply add this CSS code example:
@font-face { font-family: roboto-regular; _x000D_
src: url('../font/Roboto-Regular.ttf'); } _x000D_
h2{_x000D_
font-family: roboto-regular;_x000D_
}
_x000D_
If supported by your browser, you may use CSS3 :read-only
selector:
input[type="text"]:read-only {
cursor: normal;
background-color: #f8f8f8;
color: #999;
}
No need to trim the array, simply address it as a circular buffer (index % maxlen). This will ensure it never goes over the limit (implementing a circular buffer means that once you get to the end you wrap around to the beginning again - not possible to overrun the end of the array).
For example:
var container = new Array ();
var maxlen = 100;
var index = 0;
// 'store' 1538 items (only the last 'maxlen' items are kept)
for (var i=0; i<1538; i++) {
container [index++ % maxlen] = "storing" + i;
}
// get element at index 11 (you want the 11th item in the array)
eleventh = container [(index + 11) % maxlen];
// get element at index 11 (you want the 11th item in the array)
thirtyfifth = container [(index + 35) % maxlen];
// print out all 100 elements that we have left in the array, note
// that it doesn't matter if we address past 100 - circular buffer
// so we'll simply get back to the beginning if we do that.
for (i=0; i<200; i++) {
document.write (container[(index + i) % maxlen] + "<br>\n");
}

I can't say how much this might help you, but just found a solution to something similar problem which I faced. In the Pivot-
This would refine the data. Then, I had just copy and pasted this data in a new tab wherein I had applied the filters to my Total column with values greater than certain percentage.
This did work in my case and hope it helps you too.
For users of Contact Form 7 on Wordpress this method is working for me: I hide the v3 Recaptcha on all pages except those with Contact 7 Forms.
But this method should work on any site where you are using a unique class selector which can identify all pages with text input form elements.
First, I added a target style rule in CSS which can collapse the tile:
CSS
div.grecaptcha-badge.hide{
width:0 !important;
}
Then I added JQuery script in my header to trigger after the window loads so the 'grecaptcha-badge' class selector is available to JQuery, and can add the 'hide' class to apply the available CSS style.
$(window).load(function () {
if(!($('.wpcf7').length)){
$('.grecaptcha-badge').addClass( 'hide' );
}
});
My tile still will flash on every page for a half a second, but it's the best workaround I've found so far that I hope will comply. Suggestions for improvement appreciated.
It should work with an NSMutableURLRequest as Kuso has written.
NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: @"http://www.google.com/"]];
[urlRequest setValue: @"iPhone" forHTTPHeaderField: @"User-Agent"]; // Or any other User-Agent value.
You'll have to use NSURLConnection to get the responseData. Set the responseData to your UIWebView and the webView should render:
[webView loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)encodingName baseURL:(NSURL *)baseURL];
Just adding this for reference in case anybody needs to restart and immediatly run a command.
I'm using this approach just to clear RAM from the system. Make sure you have deleted all objects no longer required. Maybe gc()
can also help before hand. But nothing will clear RAM better as restarting the R session.
library(rstudioapi)
restartSession(command = "print('x')")
A clean solution could be create a generic class to handle the list, so you don't need to create a different class each time you need it.
public class ListModel<T>
{
public List<T> Items { get; set; }
public ListModel(List<T> list) {
Items = list;
}
}
and when you return the View you just need to simply do:
List<customClass> ListOfCustomClass = new List<customClass>();
//Do as needed...
return View(new ListModel<customClass>(ListOfCustomClass));
then define the list in the model:
@model ListModel<customClass>
and ready to go:
@foreach(var element in Model.Items) {
//do as needed...
}
Specifying a non-static position, e.g., position: absolute/relative
on a node means that it will be used as the reference for absolutely positioned elements within it http://jsfiddle.net/E5eEk/1/
See https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Positioning#Positioning_contexts
We can change the positioning context — which element the absolutely positioned element is positioned relative to. This is done by setting positioning on one of the element's ancestors.

Header names are not case sensitive.
From RFC 2616 - "Hypertext Transfer Protocol -- HTTP/1.1", Section 4.2, "Message Headers":
Each header field consists of a name followed by a colon (":") and the field value. Field names are case-insensitive.
The updating RFC 7230 does not list any changes from RFC 2616 at this part.

hsb.s = max != 0 ? 255 * delta / max : 0;
?
is a ternary operator. It works like an if
in conjunction with the :
!=
means not equals
So, the long form of this line would be
if (max != 0) { //if max is not zero
hsb.s = 255 * delta / max;
} else {
hsb.s = 0;
}
For me, the biggest benefit to re.compile
is being able to separate definition of the regex from its use.
Even a simple expression such as 0|[1-9][0-9]*
(integer in base 10 without leading zeros) can be complex enough that you'd rather not have to retype it, check if you made any typos, and later have to recheck if there are typos when you start debugging. Plus, it's nicer to use a variable name such as num or num_b10 than 0|[1-9][0-9]*
.
It's certainly possible to store strings and pass them to re.match; however, that's less readable:
num = "..."
# then, much later:
m = re.match(num, input)
Versus compiling:
num = re.compile("...")
# then, much later:
m = num.match(input)
Though it is fairly close, the last line of the second feels more natural and simpler when used repeatedly.
If you want to keep adding a new object to the array i've been using:
_methodName = (para1, para2) => {
this.setState({
arr: this.state.arr.concat({para1, para2})
})
}
Note that in an attribute selector (e.g., [attr~=value]
), the tilde
Represents an element with an attribute name of attr whose value is a whitespace-separated list of words, one of which is exactly value.

Both solutions workto simulate printf, but in a different way. For instance, to convert a value to a hex string, you have the 2 following solutions:
with format()
, closest to sprintf()
:
final static String HexChars = "0123456789abcdef";
public static String getHexQuad(long v) {
String ret;
if(v > 0xffff) ret = getHexQuad(v >> 16); else ret = "";
ret += String.format("%c%c%c%c",
HexChars.charAt((int) ((v >> 12) & 0x0f)),
HexChars.charAt((int) ((v >> 8) & 0x0f)),
HexChars.charAt((int) ((v >> 4) & 0x0f)),
HexChars.charAt((int) ( v & 0x0f)));
return ret;
}
with replace(char oldchar , char newchar)
, somewhat faster but pretty limited:
...
ret += "ABCD".
replace('A', HexChars.charAt((int) ((v >> 12) & 0x0f))).
replace('B', HexChars.charAt((int) ((v >> 8) & 0x0f))).
replace('C', HexChars.charAt((int) ((v >> 4) & 0x0f))).
replace('D', HexChars.charAt((int) ( v & 0x0f)));
...
There is a third solution consisting of just adding the char to ret
one by one (char are numbers that add to each other!) such as in:
...
ret += HexChars.charAt((int) ((v >> 12) & 0x0f)));
ret += HexChars.charAt((int) ((v >> 8) & 0x0f)));
...
...but that'd be really ugly.
As described by Herb Sutter and Scott Meyers, prefer non-friend non-member functions to member functions, to help increase encapsulation.
In some cases, like C++ streams, you won't have the choice and must use non-member functions.
But still, it does not mean you have to make these functions friends of your classes: These functions can still acess your class through your class accessors. If you succeed in writting those functions this way, then you won.
I believe the examples you gave in your question are wrong. For example;
ostream & operator<<(ostream &os) {
return os << paragraph;
}
I can't even start to think how this method could work in a stream.
Here are the two ways to implement the << and >> operators.
Let's say you want to use a stream-like object of type T.
And that you want to extract/insert from/into T the relevant data of your object of type Paragraph.
The first being as functions:
// T << Paragraph
T & operator << (T & p_oOutputStream, const Paragraph & p_oParagraph)
{
// do the insertion of p_oParagraph
return p_oOutputStream ;
}
// T >> Paragraph
T & operator >> (T & p_oInputStream, const Paragraph & p_oParagraph)
{
// do the extraction of p_oParagraph
return p_oInputStream ;
}
The second being as methods:
// T << Paragraph
T & T::operator << (const Paragraph & p_oParagraph)
{
// do the insertion of p_oParagraph
return *this ;
}
// T >> Paragraph
T & T::operator >> (const Paragraph & p_oParagraph)
{
// do the extraction of p_oParagraph
return *this ;
}
Note that to use this notation, you must extend T's class declaration. For STL objects, this is not possible (you are not supposed to modify them...).
Here are the prototypes of the same << and >> operators for C++ streams.
Note that is case of streams, as you can't modify the C++ stream, you must implement the functions. Which means something like:
// OUTPUT << Paragraph
template <typename charT, typename traits>
std::basic_ostream<charT,traits> & operator << (std::basic_ostream<charT,traits> & p_oOutputStream, const Paragraph & p_oParagraph)
{
// do the insertion of p_oParagraph
return p_oOutputStream ;
}
// INPUT >> Paragraph
template <typename charT, typename traits>
std::basic_istream<charT,traits> & operator >> (std::basic_istream<charT,traits> & p_oInputStream, const CMyObject & p_oParagraph)
{
// do the extract of p_oParagraph
return p_oInputStream ;
}
The following code will work only for char-based streams.
// OUTPUT << A
std::ostream & operator << (std::ostream & p_oOutputStream, const Paragraph & p_oParagraph)
{
// do the insertion of p_oParagraph
return p_oOutputStream ;
}
// INPUT >> A
std::istream & operator >> (std::istream & p_oInputStream, const Paragraph & p_oParagraph)
{
// do the extract of p_oParagraph
return p_oInputStream ;
}
Rhys Ulerich commented about the fact the char-based code is but a "specialization" of the generic code above it. Of course, Rhys is right: I don't recommend the use of the char-based example. It is only given here because it's simpler to read. As it is only viable if you only work with char-based streams, you should avoid it on platforms where wchar_t code is common (i.e. on Windows).
Hope this will help.
You can do it dynamically if you have custom class for edittext.
First of all you have declare state and color of edittext given below.
int[][] states = new int[][]{
new int[]{-android.R.attr.state_focused}, // enabled
new int[]{android.R.attr.state_focused}, // disabled
};
int[] colors = new int[]{
secondaryColor,
primaryColor,
};
Then Create ColorStateList variable with that
ColorStateList myList = new ColorStateList(states, colors);
Then last step is to assign it to edittext.
editText.setBackgroundTintList(myList);
After this you have to written on focused change event.
this.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View view, boolean b) {
setUnderlineColor(selectionColor,deselectionColor);
}
});
And you can make above code inside setUnderlineClor() Method,
private void setUnderlineColor(int primaryColor, int secondaryColor) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
int[][] states = new int[][]{
new int[]{-android.R.attr.state_focused}, // enabled
new int[]{android.R.attr.state_focused}, // disabled
};
int[] colors = new int[]{
secondaryColor,
primaryColor,
};
ColorStateList myList = new ColorStateList(states, colors);
setBackgroundTintList(myList);
}
}
For loading the layout in layout-land folder means you have two separate layouts then you have to make setContentView
in onConfigurationChanged
method.
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
setContentView(R.layout.yourxmlinlayout-land);
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
setContentView(R.layout.yourxmlinlayoutfolder);
}
}
If you have only one layout then no necessary to make setContentView in This method. simply
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}
you're missing group nested controls with formGroupName
directive
<div class="panel-body" formGroupName="address">
<div class="form-group">
<label for="address" class="col-sm-3 control-label">Business Address</label>
<div class="col-sm-8">

You can also use the Convert.ToString() and Convert.ToInteger() methods to convert items with DB null effectivly.
In a more general case:
N( A union B) = N(A) + N(B) - N(A intersect B)
= COUNTIFS(A1:A196,"Yes",J1:J196,"Agree")+COUNTIFS(A1:A196,"No",J1:J196,"Agree")-A1:A196,"Yes",A1:A196,"No")
The message box must end with a text and not with a variable
If you don't declare a function and it only appears after being called, it is automatically assumed to be int
, so in your case, you didn't declare
void my_print (char *);
void my_print2 (char *);
before you call it in main, so the compiler assume there are functions which their prototypes are int my_print2 (char *);
and int my_print2 (char *);
and you can't have two functions with the same prototype except of the return type, so you get the error of conflicting types
.
As Brian suggested, declare those two methods before main.
The first way
Needs root
Use kill
:
adb shell ps
=> Will list all running processes on the device and their process ids
adb shell kill <PID>
=> Instead of <PID>
use process id of your application
The second way
In Eclipse open DDMS
perspective.
In Devices
view you will find all running processes.
Choose the process and click on Stop
.
The third way
It will kill only background process of an application.
adb shell am kill [options] <PACKAGE>
=> Kill all processes associated with (the app's package name). This command kills only processes that are safe to kill and that will not impact the user experience.
Options are:
--user | all | current: Specify user whose processes to kill; all users if not specified.
The fourth way
Needs root
adb shell pm disable <PACKAGE>
=> Disable the given package or component (written as "package/class").
The fifth way
Note that run-as is only supported for apps that are signed with debug keys.
run-as <package-name> kill <pid>
The sixth way
Introduced in Honeycomb
adb shell am force-stop <PACKAGE>
=> Force stop everything associated with (the app's package name).
P.S.: I know that the sixth method didn't work for you, but I think that it's important to add this method to the list, so everyone will know it.
Try this: parseInt(jQuery.offset().top, 10)
To be safe, you should use the proper APIs in Powershell (or VBScript)
Using PowerShell:
[Environment]::GetFolderPath("Desktop")
Copy something using Powershell:
Copy-Item $home\*.txt ([Environment]::GetFolderPath("Desktop"))
Here is a VBScript-example to get the desktop path:
dim WSHShell, desktop, pathstring, objFSO
set objFSO=CreateObject("Scripting.FileSystemObject")
Set WSHshell = CreateObject("WScript.Shell")
desktop = WSHShell.SpecialFolders("Desktop")
pathstring = objFSO.GetAbsolutePathName(desktop)
WScript.Echo pathstring
To convert the current epoch time in [ms] to a 24-hour time. You might need to specify the option to disable 12-hour format.
$ node.exe -e "var date = new Date(Date.now()); console.log(date.toLocaleString('en-GB', { hour12:false } ));"
2/7/2018, 19:35:24
or as JS:
var date = new Date(Date.now());
console.log(date.toLocaleString('en-GB', { hour12:false } ));
// 2/7/2018, 19:35:24
console.log(date.toLocaleString('en-GB', { hour:'numeric', minute:'numeric', second:'numeric', hour12:false } ));
// 19:35:24
Note: The use of en-GB
here, is just a (random) choice of a place using the 24 hour format, it is not your timezone!
subversion will corrupt my project file after a svn up on an almost weekly basis. I'm trying to figure out why it does this right now and came across this problem.
As it seems impossible to filter the XPath message data (it isn't in the XML to filter), you can also use powershell to search:
Get-WinEvent -LogName System | Where-Object {$_.Message -like "*recycle*"}
From this, I can see that the event Id for recycling seems to be 5074, so you can filter on this as well. I hope this helps someone as this information seemed to take a lot longer than expected to work out.
This along with @BlackHawkDesign comment should help you find what you need.
I had the same issue. Maybe interesting to mention is that you have to configure in which cases the app pool recycle event is logged. By default it's in a couple of cases, not all of them. You can do that in IIS > app pools > select the app pool > advanced settings > expand generate recycle event log entry – BlackHawkDesign Jan 14 '15 at 10:00
I wanted to elevate this answer out of a comment section because it's one of the most elegant solutions in the thread. Full credit for this answer goes to @joeb.
pip uninstall -y -r <(pip freeze)
This worked great for me for the use case of clearing my user packages folder outside the context of a virtualenv which many of the above answers don't handle.
Edit: Anyone know how to make this command work in a Makefile?
I add this to my bash profile for convenience:
alias pipuninstallall="pip uninstall -y -r <(pip freeze)"
Then run:
pipuninstallall
If you happen to be using pipenv you can just run:
pipenv uninstall --all
First Google hit says:
this is usually a mismatch in the client/server bindings, where the message version in the service uses SOAP 1.2 (which expects application/soap+xml) and the version in the client uses SOAP 1.1 (which sends text/xml). WSHttpBinding uses SOAP 1.2, BasicHttpBinding uses SOAP 1.1.
It usually seems to be a wsHttpBinding on one side and a basicHttpBinding on the other.
First, let's make some test data:
create table client (client_id integer not null primary key auto_increment,
name varchar(64));
create table portfolio (portfolio_id integer not null primary key auto_increment,
client_id integer references client.id,
cash decimal(10,2),
stocks decimal(10,2));
insert into client (name) values ('John Doe'), ('Jane Doe');
insert into portfolio (client_id, cash, stocks) values (1, 11.11, 22.22),
(1, 10.11, 23.22),
(2, 30.30, 40.40),
(2, 40.40, 50.50);
If you didn't need the portfolio ID, it would be easy:
select client_id, name, max(cash + stocks)
from client join portfolio using (client_id)
group by client_id
+-----------+----------+--------------------+
| client_id | name | max(cash + stocks) |
+-----------+----------+--------------------+
| 1 | John Doe | 33.33 |
| 2 | Jane Doe | 90.90 |
+-----------+----------+--------------------+
Since you need the portfolio ID, things get more complicated. Let's do it in steps. First, we'll write a subquery that returns the maximal portfolio value for each client:
select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id
+-----------+----------+
| client_id | maxtotal |
+-----------+----------+
| 1 | 33.33 |
| 2 | 90.90 |
+-----------+----------+
Then we'll query the portfolio table, but use a join to the previous subquery in order to keep only those portfolios the total value of which is the maximal for the client:
select portfolio_id, cash + stocks from portfolio
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
+--------------+---------------+
| portfolio_id | cash + stocks |
+--------------+---------------+
| 5 | 33.33 |
| 6 | 33.33 |
| 8 | 90.90 |
+--------------+---------------+
Finally, we can join to the client table (as you did) in order to include the name of each client:
select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
+-----------+----------+--------------+---------------+
| client_id | name | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
| 1 | John Doe | 5 | 33.33 |
| 1 | John Doe | 6 | 33.33 |
| 2 | Jane Doe | 8 | 90.90 |
+-----------+----------+--------------+---------------+
Note that this returns two rows for John Doe because he has two portfolios with the exact same total value. To avoid this and pick an arbitrary top portfolio, tag on a GROUP BY clause:
select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
group by client_id, cash + stocks
+-----------+----------+--------------+---------------+
| client_id | name | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
| 1 | John Doe | 5 | 33.33 |
| 2 | Jane Doe | 8 | 90.90 |
+-----------+----------+--------------+---------------+
Ok, finally found the solution.
Probably due to lack of experience with ReactJS and web development...
var Task = React.createClass({
render: function() {
var percentage = this.props.children + '%';
....
<div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
...
I created the percentage variable outside in the render function.
For example: you populated your UIPickerView with array values, then you wanted
to select a certain array value in the first load of pickerView like "Arizona". Note that the word "Arizona" is at index 2. This how to do it :) Enjoy coding.
NSArray *countryArray =[NSArray arrayWithObjects:@"Alabama",@"Alaska",@"Arizona",@"Arkansas", nil];
UIPickerView *countryPicker=[[UIPickerView alloc]initWithFrame:self.view.bounds];
countryPicker.delegate=self;
countryPicker.dataSource=self;
[countryPicker selectRow:2 inComponent:0 animated:YES];
[self.view addSubview:countryPicker];

I think Firebug does it differently than Chrome's dev tools. It looks like Firebug gives you a stringified version of the object while console.dir
gives you an expandable object. Both give you the expandable object in Chrome, and I think that's where the confusion might come from. Or it's just a bug in Chrome.
In Chrome, both do the same thing. Expanding on your test, I have noticed that Chrome gets the current value of the object when you expand it.
> o = { foo: 1 }
> console.log(o)
Expand now, o.foo = 1
> o.foo = 2
o.foo is still displayed as 1 from previous lines
> o = { foo: 1 }
> console.log(o)
> o.foo = 2
Expand now, o.foo = 2
You can use the following to get a stringified version of an object if that's what you want to see. This will show you what the object is at the time this line is called, not when you expand it.
console.log(JSON.stringify(o));
There are several threads, there's even a "topmost" tag. Search on that, or go directly to this post which looks good:

You want to set height which may set for all devices?
Decide upon the design of the site i.e Height on various devices.
Ex:
Height-100px
for bubbles on device with -min-width: 700px
.Height-50px
for bubbles on device with < 700px
;Have your css which has height 50px;
and add this media query
@media only screen and (min-width: 700px) {
/* Styles */
.bubble {
height: 100px;
margin: 20px;
}
.bubble:after {
bottom: -50px;
border-width: 50px 50px 0;
}
.bubble:before {
top: 100px;
border-width: 52px 52px 0;
}
.bubble1 {
height: 100px;
margin: 20px;
}
.bubble1:after {
bottom: -50px;
border-width: 50px 50px 0;
}
.bubble1:before {
top: 100px;
border-width: 52px 52px 0;
}
.bubble2 {
height: 100px;
margin: 20px;
}
.bubble2:after {
bottom: -50px;
border-width: 50px 50px 0;
}
.bubble2:before {
top: 100px;
border-width: 52px 52px 0;
}
}
This will make your bubbles have Height of 100px on devices greater than 700px and a margin of 20px;

If you use mutexes to protect all your data, you really shouldn't need to worry. Mutexes have always provided sufficient ordering and visibility guarantees.
Now, if you used atomics, or lock-free algorithms, you need to think about the memory model. The memory model describes precisely when atomics provide ordering and visibility guarantees, and provides portable fences for hand-coded guarantees.
Previously, atomics would be done using compiler intrinsics, or some higher level library. Fences would have been done using CPU-specific instructions (memory barriers).
You could use the substr
function to return a substring starting from the 5th character:
$str = "The quick brown fox jumps over the lazy dog."
$str2 = substr($str, 4); // "quick brown fox jumps over the lazy dog."

All Google Maps JavaScript API applications require authentication( API KEY )

You shouldn't have to unserialize anything in PHP from the jquery serialize
method. If you serialize the data, it should be sent to PHP as query parameters if you are using a GET method ajax request or post vars if you are using a POST ajax request. So in PHP, you would access values like $_POST["varname"]
or $_GET["varname"]
depending on the request type.
The serialize
method just takes the form elements and puts them in string form. "varname=val&var2=val2"
I'd like to suggest automatic way with gradle only

Yet another flexible and fast way
template<typename Operator>
void tokenize(Operator& op, const char* input, const char* delimiters) {
const char* s = input;
const char* e = s;
while (*e != 0) {
e = s;
while (*e != 0 && strchr(delimiters, *e) == 0) ++e;
if (e - s > 0) {
op(s, e - s);
}
s = e + 1;
}
}
To use it with a vector of strings (Edit: Since someone pointed out not to inherit STL classes... hrmf ;) ) :
template<class ContainerType>
class Appender {
public:
Appender(ContainerType& container) : container_(container) {;}
void operator() (const char* s, unsigned length) {
container_.push_back(std::string(s,length));
}
private:
ContainerType& container_;
};
std::vector<std::string> strVector;
Appender v(strVector);
tokenize(v, "A number of words to be tokenized", " \t");
That's it! And that's just one way to use the tokenizer, like how to just count words:
class WordCounter {
public:
WordCounter() : noOfWords(0) {}
void operator() (const char*, unsigned) {
++noOfWords;
}
unsigned noOfWords;
};
WordCounter wc;
tokenize(wc, "A number of words to be counted", " \t");
ASSERT( wc.noOfWords == 7 );
Limited by imagination ;)
This may be created sql injection point "SQL Injection Piggy-backed Queries". attackers able to append multiple malicious sql statements. so do not append user inputs directly to the queries.
Security considerations
The API functions mysqli_query() and mysqli_real_query() do not set a connection flag necessary for activating multi queries in the server. An extra API call is used for multiple statements to reduce the likeliness of accidental SQL injection attacks. An attacker may try to add statements such as ; DROP DATABASE mysql or ; SELECT SLEEP(999). If the attacker succeeds in adding SQL to the statement string but mysqli_multi_query is not used, the server will not execute the second, injected and malicious SQL statement.
Because C++ inherited them from C. Unfortunately.
The code using NetworkInterface to wait for the network worked for me until I switched from fixed network address to DHCP. A slight enhancement makes it work also with DHCP:
Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
while (interfaces.hasMoreElements()) {
NetworkInterface interf = interfaces.nextElement();
if (interf.isUp() && !interf.isLoopback()) {
List<InterfaceAddress> adrs = interf.getInterfaceAddresses();
for (Iterator<InterfaceAddress> iter = adrs.iterator(); iter.hasNext();) {
InterfaceAddress adr = iter.next();
InetAddress inadr = adr.getAddress();
if (inadr instanceof Inet4Address) return true;
}
}
}
This works for Java 7 in openSuse 13.1 for IPv4 network. The problem with the original code is that although the interface was up after resuming from suspend, an IPv4 network address was not yet assigned. After waiting for this assignment, the program can connect to servers. But I have no idea what to do in case of IPv6.
Simply use the .rules('add')
method immediately after creating the element...
var filenumber = 1;
$("#AddFile").click(function () { //User clicks button #AddFile
// create the new input element
$('<li><input type="file" name="FileUpload' + filenumber + '" id="FileUpload' + filenumber + '" /> <a href="#" class="RemoveFileUpload">Remove</a></li>').prependTo("#FileUploader");
// declare the rule on this newly created input field
$('#FileUpload' + filenumber).rules('add', {
required: true, // <- with this you would not need 'required' attribute on input
accept: "image/jpeg, image/pjpeg"
});
filenumber++; // increment counter for next time
return false;
});
You'll still need to use .validate()
to initialize the plugin within a DOM ready handler.
You'll still need to declare rules for your static elements using .validate()
. Whatever input elements that are part of the form when the page loads... declare their rules within .validate()
.
You don't need to use .each()
, when you're only targeting ONE element with the jQuery selector attached to .rules()
.
You don't need the required
attribute on your input element when you're declaring the required
rule using .validate()
or .rules('add')
. For whatever reason, if you still want the HTML5 attribute, at least use a proper format like required="required"
.

I really like cdmckay's answer, but it does not really look good to check the size in a real time: it is just too slow (2 seconds for me). This is the improved version, which is way faster and more exact, also with an option to choose how big the error can be (default 250,000
, the smaller error is - the longer the calculation is):
function getLocalStorageMaxSize(error) {
if (localStorage) {
var max = 10 * 1024 * 1024,
i = 64,
string1024 = '',
string = '',
// generate a random key
testKey = 'size-test-' + Math.random().toString(),
minimalFound = 0,
error = error || 25e4;
// fill a string with 1024 symbols / bytes
while (i--) string1024 += 1e16;
i = max / 1024;
// fill a string with 'max' amount of symbols / bytes
while (i--) string += string1024;
i = max;
// binary search implementation
while (i > 1) {
try {
localStorage.setItem(testKey, string.substr(0, i));
localStorage.removeItem(testKey);
if (minimalFound < i - error) {
minimalFound = i;
i = i * 1.5;
}
else break;
} catch (e) {
localStorage.removeItem(testKey);
i = minimalFound + (i - minimalFound) / 2;
}
}
return minimalFound;
}
}
To test:
console.log(getLocalStorageMaxSize()); // takes .3s
console.log(getLocalStorageMaxSize(.1)); // takes 2s, but way more exact
This works dramatically faster for the standard error; also it can be much more exact when necessary.
xlim
and ylim
don't cut it here. You need to use expand_limits
, scale_x_continuous
, and scale_y_continuous
. Try:
df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for
p + scale_x_continuous(expand = c(0, 0)) + scale_y_continuous(expand = c(0, 0))
You may need to adjust things a little to make sure points are not getting cut off (see, for example, the point at x = 5
and y = 5
.
You have to understand how Unix interprets your input.
The standard Unix shell interpolates environment variables, and what are called globs before it passes the parameters to your program. This is a bit different from Windows which makes the program interpret the expansion.
Try this:
$ echo *
This will echo all the files and directories in your current directory. Before the echo
command acts, the shell interpolates the *
and expands it, then passes that expanded parameter back to your command. You can see it in action by doing this:
$ set -xv
$ echo *
$ set +xv
The set -xv
turns on xtrace and verbose. Verbose echoes the command as entered, and xtrace echos the command that will be executed (that is, after the shell expansion).
Now try this:
$ echo "*"
Note that putting something inside quotes hides the glob expression from the shell, and the shell cannot expand it. Try this:
$ foo="this is the value of foo"
$ echo $foo
$ echo "$foo"
$ echo '$foo'
Note that the shell can still expand environment variables inside double quotes, but not in single quotes.
Now let's look at your statement:
file="home/edward/bank1/fiche/Test*"
The double quotes prevent the shell from expanding the glob expression, so file
is equal to the literal home/edward/bank1/finche/Test*
. Therefore, you need to do this:
file=/home/edward/bank1/fiche/Test*
The lack of quotes (and the introductory slash which is important!) will now make file equal to all files that match that expression. (There might be more than one!). If there are no files, depending upon the shell, and its settings, the shell may simply set file to that literal string anyway.
You certainly have the right idea:
file=/home/edward/bank1/fiche/Test*
if test -s $file
then
echo "found one"
else
echo "found none"
fi
However, you still might get found none returned if there is more than one file. Instead, you might get an error in your test
command because there are too many parameters.
One way to get around this might be:
if ls /home/edward/bank1/finche/Test* > /dev/null 2>&1
then
echo "There is at least one match (maybe more)!"
else
echo "No files found"
fi
In this case, I'm taking advantage of the exit code of the ls
command. If ls
finds one file it can access, it returns a zero exit code. If it can't find one matching file, it returns a non-zero exit code. The if
command merely executes a command, and then if the command returns a zero, it assumes the if
statement as true and executes the if
clause. If the command returns a non-zero value, the if
statement is assumed to be false, and the else
clause (if one is available) is executed.
The test
command works in a similar fashion. If the test
is true, the test
command returns a zero. Otherwise, the test
command returns a non-zero value. This works great with the if
command. In fact, there's an alias to the test
command. Try this:
$ ls -li /bin/test /bin/[
The i
prints out the inode. The inode is the real ID of the file. Files with the same ID are the same file. You can see that /bin/test
and /bin/[
are the same command. This makes the following two commands the same:
if test -s $file
then
echo "The file exists"
fi
if [ -s $file ]
then
echo "The file exists"
fi
Just one slight improvement on Jerrin's answer on fixing this error with Ubuntu 18.04 by utilizing $USER
variable available in the bash terminal. So you could use the following commands two commands:
sudo apt install qemu-kvm
Add the current user to the kvm group
sudo adduser $USER kvm
Also if you are still having issues, one other problem for me was the way in which I installed Ubuntu. I made the mistake of checking the box during installation for installing 3rd party software which did not play nice with my nvidia graphics card for development. So I reinstalled Ubuntu with this third party software unchecked.
Then after installation, open up Software & Updates and go to the Additional Drivers tab. Select the most up to date proprietary drivers that have also been tested and apply changes. Should restart the machine for the changes to take affect.
Since dates are converted to UNIX epoch (numbers), you can use Math.max/min to find those:
var maxDate = Math.max.apply(null, dates)
// convert back to date object
maxDate = new Date(maxDate)
(tested in chrome only, but should work in most browsers)
It is the ternary conditional operator.
If the condition in the parenthesis before the ?
is true, it returns the value to the left of the :
, otherwise the value to the right.
open command prompt and type
cd\ (enter)
then type
start chrome "www.google.com"(any website you require)
**The best is to use try except block to get rid of EOF **
try:
width = input()
height = input()
def rectanglePerimeter(width, height):
return ((width + height)*2)
print(rectanglePerimeter(width, height))
except EOFError as e:
print(end="")
Or just try this after each text passage for a new line.
$pdf->Write(0, ' ', '*', 0, 'C', TRUE, 0, false, false, 0) ;
To list tags I prefer:
git tag -n
The -n
flag displays the first line of the annotation message along with the tag, or the first commit message line if the tag is not annotated.
You can also do git tag -n5
to show the first 5 lines of the annotation.
The reason must be somewhere else. Using only Spring Boot 1.2.2 out of the box with no configuration, it Just Works. Have a look at this repo - can you get it to break?
https://github.com/konrad-garus/so-yaml
Are you sure the YAML file looks exactly the way you pasted? No extra whitespace, characters, special characters, mis-indentation or something of that sort? Is it possible you have another file elsewhere in the search path that is used instead of the one you're expecting?
On OS X High Sierra, I had to do this:
sudo install -d -o $(whoami) -g admin /usr/local/Frameworks
brew uninstall --ignore-dependencies python
brew install python
python --version # should work, returns 2.7, which is a Python thing (it's weird, but ok)

thank you for your correct. link for customize bootstrap: https://getbootstrap.com/docs/3.4/customize/
If you want to avoid adding extra dependencies, I found node's process.argv
to be useful:
gulp.task('mytask', function() {
console.log(process.argv);
});
So the following:
gulp mytask --option 123
should display:
[ 'node', 'path/to/gulp.js', 'mytask', '--option', '123']
If you are sure that the desired parameter is in the right position, then the flags aren't needed.** Just use (in this case):
var option = process.argv[4]; //set to '123'
BUT: as the option may not be set, or may be in a different position, I feel that a better idea would be something like:
var option, i = process.argv.indexOf("--option");
if(i>-1) {
option = process.argv[i+1];
}
That way, you can handle variations in multiple options, like:
//task should still find 'option' variable in all cases
gulp mytask --newoption somestuff --option 123
gulp mytask --option 123 --newoption somestuff
gulp mytask --flag --option 123
** Edit: true for node scripts, but gulp interprets anything without a leading "--" as another task name. So using gulp mytask 123
will fail because gulp can't find a task called '123'.
When you use a function ...
<p onclick="update_url('/en/step2');">Link</p>
<script>
function update_url(url) {
history.pushState(null, null, url);
}
</script>
private boolean isOnlyLetters(String s){
char c=' ';
boolean isGood=false, safe=isGood;
int failCount=0;
for(int i=0;i<s.length();i++){
c = s.charAt(i);
if(Character.isLetter(c))
isGood=true;
else{
isGood=false;
failCount+=1;
}
}
if(failCount==0 && s.length()>0)
safe=true;
else
safe=false;
return safe;
}
I know it's a bit crowded. I was using it with my program and felt the desire to share it with people. It can tell if any character in a string is not a letter or not. Use it if you want something easy to clarify and look back on.
x = 10;
if(x > 100 ) console.log('over 100')
else if (x > 90 ) console.log('over 90')
else if (x > 50 ) console.log('over 50')
else if (x > 9 ) console.log('over 9')
else console.log('lower 9')
First make a string with all your possible characters:
$characters = 'abcdefghijklmnopqrstuvwxyz0123456789';
You could also use range() to do this more quickly.
Then, in a loop, choose a random number and use it as the index to the $characters
string to get a random character, and append it to your string:
$string = '';
$max = strlen($characters) - 1;
for ($i = 0; $i < $random_string_length; $i++) {
$string .= $characters[mt_rand(0, $max)];
}
$random_string_length
is the length of the random string.
-n
returns line number.
-i
is for ignore-case. Only to be used if case matching is not necessary
$ grep -in null myfile.txt
2:example two null,
4:example four null,
Combine with awk
to print out the line number after the match:
$ grep -in null myfile.txt | awk -F: '{print $2" - Line number : "$1}'
example two null, - Line number : 2
example four null, - Line number : 4
Use command substitution to print out the total null count:
$ echo "Total null count :" $(grep -ic null myfile.txt)
Total null count : 2
int day = (int)DateTime.Now.DayOfWeek;
First day of the week: Sunday (with a value of zero)
You can use django-overextends, which provides circular template inheritance for Django.
It comes from the Mezzanine CMS, from where Stephen extracted it into a standalone Django extension.
More infos you find in "Overriding vs Extending Templates" (http:/mezzanine.jupo.org/docs/content-architecture.html#overriding-vs-extending-templates) inside the Mezzanine docs.
For deeper insides look at Stephens Blog "Circular Template Inheritance for Django" (http:/blog.jupo.org/2012/05/17/circular-template-inheritance-for-django).
And in Google Groups the discussion (https:/groups.google.com/forum/#!topic/mezzanine-users/sUydcf_IZkQ) which started the development of this feature.

I don't have the reputation to add more than 2 links. But I think the links provide interesting background information. So I just left out a slash after "http(s):". Maybe someone with better reputation can repair the links and remove this note.

This should give you the current date minus 1 year:

If you really want to get the type by name you may use the following:
System.AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()).First(x => x.Name == "theassembly");
Note that you can improve the performance of this drastically the more information you have about the type you're trying to load.
If you want to extract just a simple piece of information, you can get that using git show
with the --format=<string>
option...and ask it not to give you the diff with --no-patch
. This means you can get a printf-style output of whatever you want, which might often be a single field.
For instance, to get just the shortened hash (%h
) you could say:
$ git show --format="%h" --no-patch
4b703eb
If you're looking to save that into an environment variable in bash (a likely thing for people to want to do) you can use the $()
syntax:
$ GIT_COMMIT="$(git show --format="%h" --no-patch)"
$ echo $GIT_COMMIT
4b703eb
The full list of what you can do is in git show --help
. But here's an abbreviated list of properties that might be useful:

If the element is currently not visible on the page, you can use the native scrollIntoView()
method.
$('#div_' + element_id)[0].scrollIntoView( true );
Where true
means align to the top of the page, and false
is align to bottom.
Otherwise, there's a scrollTo()
plugin for jQuery you can use.
Or maybe just get the top
position()
(docs) of the element, and set the scrollTop()
(docs) to that position:
var top = $('#div_' + element_id).position().top;
$(window).scrollTop( top );
