here in this code first we are creating RSA key which is private but it has pair of its public key as well so to get your actual public key we simply do this
openssl rsa -in mykey.pem -pubout > mykey.pub

I'm not an expert, but I guess in sed
you'd first need to append the next line into the pattern space, bij using "N
". From the section "Multiline Pattern Space" in "Advanced sed Commands" of the book sed & awk (Dale Dougherty and Arnold Robbins; O'Reilly 1997; page 107 in the preview):
The multiline Next (N) command creates a multiline pattern space by reading a new line of input and appending it to the contents of the pattern space. The original contents of pattern space and the new input line are separated by a newline. The embedded newline character can be matched in patterns by the escape sequence "\n". In a multiline pattern space, the metacharacter "^" matches the very first character of the pattern space, and not the character(s) following any embedded newline(s). Similarly, "$" matches only the final newline in the pattern space, and not any embedded newline(s). After the Next command is executed, control is then passed to subsequent commands in the script.
From man sed
:
[2addr]N
Append the next line of input to the pattern space, using an embedded newline character to separate the appended material from the original contents. Note that the current line number changes.
I've used this to search (multiple) badly formatted log files, in which the search string may be found on an "orphaned" next line.
try to run the code below
- (void)viewDidLoad {
[super viewDidLoad];
UIWindow *w = [[UIApplication sharedApplication] keyWindow];
UIView *v = [w.subviews objectAtIndex:0];
NSLog(@"%@", NSStringFromCGRect(v.frame));
NSLog(@"%@", NSStringFromCGRect(v.bounds));
}
the output of this code is:
case device orientation is Portrait
{{0, 0}, {768, 1024}}
{{0, 0}, {768, 1024}}
case device orientation is Landscape
{{0, 0}, {768, 1024}}
{{0, 0}, {1024, 768}}
obviously, you can see the difference between frame and bounds
In the list view you can add android:listselector=color name that you want.

As Sahil Chhabra suggested you can use @JsonFormat
with proper shape
on your variable.
In case you would like to apply it on every BigDecimal
field you have in your Dto's
you can override default format for given class.
@Configuration
public class JacksonObjectMapperConfiguration {
@Autowired
public void customize(ObjectMapper objectMapper) {
objectMapper
.configOverride(BigDecimal.class).setFormat(JsonFormat.Value.forShape(JsonFormat.Shape.STRING));
}
}
The answer here is correct, I however struggled to implement it in an ASP.NET MVC 3 app. I wanted to access a Session object in a controller and couldn't figure out why I kept on getting a "Instance not set to an instance of an Object error". What I noticed is that in a controller when I tried to access the session by doing the following, I kept on getting that error. This is due to the fact that this.HttpContext is part of the Controller object.
this.Session["blah"]
// or
this.HttpContext.Session["blah"]
However, what I wanted was the HttpContext that's part of the System.Web namespace because this is the one the Answer above suggests to use in Global.asax.cs. So I had to explicitly do the following:
System.Web.HttpContext.Current.Session["blah"]
this helped me, not sure if I did anything that isn't M.O. around here, but I hope it helps someone!
The pattern matches all non-digit characters. This will restrict you to non-negative integers, but for your example it will be more than sufficient.
string input = "0, 10, 20, 30, 100, 200";
Regex.Split(input, @"\D+");
The internals of the GUI system call that method, and they pass in the Graphics

It worked for me, just leave it to the jQuery.
$("html,body").animate({ scrollTop: 0 }, 1);
Basically you should know the browser and write the code considering browser differences. Since jQuery is cross-browser it should handle the first step. And finally you fake the js-engine of the browser by animating the scrolling in 1 millisecond.
This depends on the language being used. You wrote 'language-agnostic', so I'll give some examples.
In Java, C, and Python, recursion is fairly expensive compared to iteration (in general) because it requires the allocation of a new stack frame. In some C compilers, one can use a compiler flag to eliminate this overhead, which transforms certain types of recursion (actually, certain types of tail calls) into jumps instead of function calls.
In functional programming language implementations, sometimes, iteration can be very expensive and recursion can be very cheap. In many, recursion is transformed into a simple jump, but changing the loop variable (which is mutable) sometimes requires some relatively heavy operations, especially on implementations which support multiple threads of execution. Mutation is expensive in some of these environments because of the interaction between the mutator and the garbage collector, if both might be running at the same time.
I know that in some Scheme implementations, recursion will generally be faster than looping.
In short, the answer depends on the code and the implementation. Use whatever style you prefer. If you're using a functional language, recursion might be faster. If you're using an imperative language, iteration is probably faster. In some environments, both methods will result in the same assembly being generated (put that in your pipe and smoke it).
Addendum: In some environments, the best alternative is neither recursion nor iteration but instead higher order functions. These include "map", "filter", and "reduce" (which is also called "fold"). Not only are these the preferred style, not only are they often cleaner, but in some environments these functions are the first (or only) to get a boost from automatic parallelization — so they can be significantly faster than either iteration or recursion. Data Parallel Haskell is an example of such an environment.
List comprehensions are another alternative, but these are usually just syntactic sugar for iteration, recursion, or higher order functions.
This is the best and easiest code:
public class test
{
public static void main(String str[])
{
String jsonString = "{\"stat\": { \"sdr\": \"aa:bb:cc:dd:ee:ff\", \"rcv\": \"aa:bb:cc:dd:ee:ff\", \"time\": \"UTC in millis\", \"type\": 1, \"subt\": 1, \"argv\": [{\"type\": 1, \"val\":\"stackoverflow\"}]}}";
JSONObject jsonObject = new JSONObject(jsonString);
JSONObject newJSON = jsonObject.getJSONObject("stat");
System.out.println(newJSON.toString());
jsonObject = new JSONObject(newJSON.toString());
System.out.println(jsonObject.getString("rcv"));
System.out.println(jsonObject.getJSONArray("argv"));
}
}

If you think that there is a conflict you can use jQuery.noConflict()
in your code. Details are in the docs.
REFERENCING MAGIC - SHORTCUTS FOR JQUERY
If you don't like typing the full "jQuery" all the time, there are some alternative shortcuts:
Reassign jQuery to another shortcut
var $j = jQuery;
(This might be the best approach if you wish to use different libraries) Use the following technique, which allows you to use $ inside of a block of code without permanently overwriting $:
(function($) { /* some code that uses $ */ })(jQuery)
Note: If you use this technique, you will not be able to use Prototype methods inside this capsuled function that expect $ to be Prototype's $, so you're making a choice to use only jQuery in that block. Use the argument to the DOM ready event:
jQuery(function($) { /*some code that uses $ */ });
Note: Again, inside that block you can't use Prototype methods
Thats from the end of the docs and might be useful to you
Use
find \( -path "./tmp" -o -path "./scripts" \) -prune -o -name "*_peaks.bed" -print
or
find \( -path "./tmp" -o -path "./scripts" \) -prune -false -o -name "*_peaks.bed"
or
find \( -path "./tmp" -path "./scripts" \) ! -prune -o -name "*_peaks.bed"
The order is important. It evaluates from left to right. Always begin with the path exclusion.
Do not use -not
(or !
) to exclude whole directory. Use -prune
.
As explained in the manual:
-prune The primary shall always evaluate as true; it
shall cause find not to descend the current
pathname if it is a directory. If the -depth
primary is specified, the -prune primary shall
have no effect.
and in the GNU find manual:
-path pattern
[...]
To ignore a whole
directory tree, use -prune rather than checking
every file in the tree.
Indeed, if you use -not -path "./pathname"
,
find will evaluate the expression for each node under "./pathname"
.
find expressions are just condition evaluation.
\( \)
- groups operation (you can use -path "./tmp" -prune -o -path "./scripts" -prune -o
, but it is more verbose).-path "./script" -prune
- if -path
returns true and is a directory, return true for that directory and do not descend into it.-path "./script" ! -prune
- it evaluates as (-path "./script") AND (! -prune)
. It revert the "always true" of prune to always false. It avoids printing "./script"
as a match.-path "./script" -prune -false
- since -prune
always returns true, you can follow it with -false
to do the same than !
.-o
- OR operator. If no operator is specified between two expressions, it defaults to AND operator.Hence, \( -path "./tmp" -o -path "./scripts" \) -prune -o -name "*_peaks.bed" -print
is expanded to:
[ (-path "./tmp" OR -path "./script") AND -prune ] OR ( -name "*_peaks.bed" AND print )
The print is important here because without it is expanded to:
{ [ (-path "./tmp" OR -path "./script" ) AND -prune ] OR (-name "*_peaks.bed" ) } AND print
-print
is added by find - that is why most of the time, you do not need to add it in you expression. And since -prune
returns true, it will print "./script" and "./tmp".
It is not necessary in the others because we switched -prune
to always return false.
Hint: You can use find -D opt expr 2>&1 1>/dev/null
to see how it is optimized and expanded,
find -D search expr 2>&1 1>/dev/null
to see which path is checked.

SET PhoneNumber = SUBSTRING(PhoneNumber, 1, 3) + '-' +
SUBSTRING(PhoneNumber, 4, 3) + '-' +
SUBSTRING(PhoneNumber, 7, 4)
Incorporated Kane's suggestion, you can compute the phone number's formatting at runtime. One possible approach would be to use scalar functions for this purpose (works in SQL Server):
CREATE FUNCTION FormatPhoneNumber(@phoneNumber VARCHAR(10))
RETURNS VARCHAR(12)
BEGIN
RETURN SUBSTRING(@phoneNumber, 1, 3) + '-' +
SUBSTRING(@phoneNumber, 4, 3) + '-' +
SUBSTRING(@phoneNumber, 7, 4)
END

If all your branches make side-effects or are computationally expensive the following would a semantically-preserving refactoring:
index := func() int {
if val > 0 {
return printPositiveAndReturn(val)
} else {
return slowlyReturn(-val) // or slowlyNegate(val)
}
}(); # exactly one branch will be evaluated
with normally no overhead (inlined) and, most importantly, without cluttering your namespace with a helper functions that are only used once (which hampers readability and maintenance). Live Example
Note if you were to naively apply Gustavo's approach:
index := printPositiveAndReturn(val);
if val <= 0 {
index = slowlyReturn(-val); // or slowlyNegate(val)
}
you'd get a program with a different behavior; in case val <= 0
program would print a non-positive value while it should not! (Analogously, if you reversed the branches, you would introduce overhead by calling a slow function unnecessarily.)
It should be pretty obvious from your question that you're actually just asking about the difference between git merge
and git rebase
.
So let's suppose you're in the common case - you've done some work on your master branch, and you pull from origin's, which also has done some work. After the fetch, things look like this:
- o - o - o - H - A - B - C (master)
\
P - Q - R (origin/master)
If you merge at this point (the default behavior of git pull), assuming there aren't any conflicts, you end up with this:
- o - o - o - H - A - B - C - X (master)
\ /
P - Q - R --- (origin/master)
If on the other hand you did the appropriate rebase, you'd end up with this:
- o - o - o - H - P - Q - R - A' - B' - C' (master)
|
(origin/master)
The content of your work tree should end up the same in both cases; you've just created a different history leading up to it. The rebase rewrites your history, making it look as if you had committed on top of origin's new master branch (R
), instead of where you originally committed (H
). You should never use the rebase approach if someone else has already pulled from your master branch.
Finally, note that you can actually set up git pull
for a given branch to use rebase instead of merge by setting the config parameter branch.<name>.rebase
to true. You can also do this for a single pull using git pull --rebase
.
Jon's disassemblies show, that the difference between the two versions is that the fast version uses a pair of registers (esi,edi
) to store one of the local variables where the slow version doesn't.
The JIT compiler makes different assumptions regarding register use for code that contains a try-catch block vs. code which doesn't. This causes it to make different register allocation choices. In this case, this favors the code with the try-catch block. Different code may lead to the opposite effect, so I would not count this as a general-purpose speed-up technique.
In the end, it's very hard to tell which code will end up running the fastest. Something like register allocation and the factors that influence it are such low-level implementation details that I don't see how any specific technique could reliably produce faster code.
For example, consider the following two methods. They were adapted from a real-life example:
interface IIndexed { int this[int index] { get; set; } }
struct StructArray : IIndexed {
public int[] Array;
public int this[int index] {
get { return Array[index]; }
set { Array[index] = value; }
}
}
static int Generic<T>(int length, T a, T b) where T : IIndexed {
int sum = 0;
for (int i = 0; i < length; i++)
sum += a[i] * b[i];
return sum;
}
static int Specialized(int length, StructArray a, StructArray b) {
int sum = 0;
for (int i = 0; i < length; i++)
sum += a[i] * b[i];
return sum;
}
One is a generic version of the other. Replacing the generic type with StructArray
would make the methods identical. Because StructArray
is a value type, it gets its own compiled version of the generic method. Yet the actual running time is significantly longer than the specialized method's, but only for x86. For x64, the timings are pretty much identical. In other cases, I've observed differences for x64 as well.

selects immediate childrenFor example, if you have nested divs like such:
<div class='outer'>
<div class="middle">
<div class="inner">...</div>
</div>
<div class="middle">
<div class="inner">...</div>
</div>
</div>
and you declare a css rule in your stylesheet like such:
.outer > div {

}
your rules will apply only to those divs that have a class of "middle" since those divs are direct descendants (immediate children) of elements with class "outer" (unless, of course, you declare other, more specific rules overriding these rules). See fiddle.

If you, instead, had a space between selectors instead of

As some people indicated, the officially accepted answer does not quite return the external removable SD card. And i ran upon the following thread that proposes a method I've tested on some Android devices and seems to work reliably, so i thought of re-sharing here as i don't see it in the other responses:

Kudos to paresh996 for coming up with the answer itself, and i can attest I've tried on Samsung S7 and S7edge and seems to work.
Now, i needed a method that returned a valid path where to read files, and that considered the fact that there might not be an external SD, in which case the internal storage should be returned, so i modified the code from paresh996 to this :
File getStoragePath() {
String removableStoragePath;
File fileList[] = new File("/storage/").listFiles();
for (File file : fileList) {
if(!file.getAbsolutePath().equalsIgnoreCase(Environment.getExternalStorageDirectory().getAbsolutePath()) && file.isDirectory() && file.canRead()) {
return file;
}
}
return Environment.getExternalStorageDirectory();
}
I didn't like that the map would load only after the hidden div had become visible. In a carousel, for example, that doesn't really work.
This my solution is to add class to the hidden element to unhide it and hide it with position absolute instead, then render the map, and remove the class after map load.
Tested in Bootstrap Carousel.
HTML
<div class="item loading"><div id="map-canvas"></div></div>
CSS
.loading { display: block; position: absolute; }
JS
$(document).ready(function(){
// render map //
google.maps.event.addListenerOnce(map, 'idle', function(){
$('.loading').removeClass('loading');
});
}
string textValue = ((ListBoxItem)listBox1.SelectedItem).Content.ToString();
No, and the fact that you want to seems like a bad idea. Do you really need a default constructor like this?

If you don't need jvm is disabled check "Install Bundled / Downloaded Virtual Machine" option in the checkbox (project - JVM settings - Installer Settings - Bundled/Downloaded Virtual Machine).
If you need jvm is disabled because you create it manually, then you can do the following: create an action "Modify Text File" to append variable with the value of the _jvm folder.

I found myself requiring this functionality often enough that I packaged it into a library called std-pour. It should let you execute a command and view the output in real time. To install simply:

echo "mysql-server-5.5 mysql-server/root_password_again password root" | debconf-set-selections
apt-get -y install mysql-server-5.5
Note that this simply sets the password to "root". I could not get it to set a blank password using simple quotes ''
, but this solution was sufficient for me.
Based on a solution here.
In my case, this error was due to incorrect paths used to specify intents in my preferences xml file after I renamed the project. For instance, where I had:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.olddirectory"
android:targetClass="com.ssimon.olddirectory.RecipeEditActivity"/>
</Preference>
</PreferenceScreen>
I needed the following instead:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.newdirectory"
android:targetClass="com.ssimon.newdirectory.RecipeEditActivity"/>
</Preference>
Correcting the path names fixed the problem.
Another way I just found!
MOVE the project to some other folder and then import and if required copy to workspace
The following WON'T WORK. It causes another issue. It will now do the 100% width but it won't be responsive on smaller devices:
.table-responsive {
display: table;
}
All these answers introduced another problem by recommending display: table;
. The only solution as of right now is to use it as a wrapper:
<div class="table-responsive">
<table class="table">
...
</table>
</div>
Possibly worth noting that if you're still in your editor with the commit message, you can delete the commit message and it will abort the git commit --amend
command.
The difference between a string (or to be precise, std::string
) and a character literal is that for the latter there is no +
operator defined. This is why the second example fails.
In the first case, the compiler can find a suitable operator+
with the first argument being a string
and the second a character literal (const char*
) so it used that. The result of that operation is again a string
, so it repeats the same trick when adding "!"
to it.
Additionally, you will see that float
values are rounded.
// e.g: given values 41.0473112,29.0077011 float(11,7) | decimal(11,7) --------------------------- 41.0473099 | 41.0473112 29.0077019 | 29.0077011
I prefer defining function as variable:
let first = function(x){
return x[0];
}
Instead of:
function first(){
....
}
Because i can use expressions and decorators when defining the function. For example:
let safe = function(f){
try {f()...}
}
let last = safe(function(x){return x[0]}).
Also with ES6 its much shorter:
let last = x => x[0]
...........
function last(x){
return x[0];
}
......
let last = safe(x => x[0]);
Yes, it is possible.

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

You could call during init or whatever Locale.setDefault() or -Duser.language=, -Duser.country=, and -Duser.variant= at the command line. Here's something on Sun's site.

I've been having similar issues of a video not playing in IE11 on Windows 8.1. What I didn't realize was that I was running an N version of Windows, meaning no media features were installed. After installing the Media Feature Pack for N and KN versions of Windows 8.1 and rebooting my PC it was working fine.
As a side-note, the video worked fine in Chrome, Firefox, etc, since those browsers properly fell back to the webm
file.
To apply it everywhere, you could do something like
$('body').on('click', function() {
if($('.children').is(':visible')) {
$('ul.children').slideUp('slow');
}
});

If you're going for simple, you can avoid the "new" keyword entirely and just use factory methods. I prefer this, sometimes, because I like using JSON to create objects.
function getSomeObj(var1, var2){
var obj = {
instancevar1: var1,
instancevar2: var2,
someMethod: function(param)
{
//stuff;
}
};
return obj;
}
var myobj = getSomeObj("var1", "var2");
myobj.someMethod("bla");
I'm not sure what the performance hit is for large objects, though.

A simpler answer.
function ($quantity) use ($tax, &$total) { .. };
$tax
inside the closure has no external effect, unless it is a pointer, like an object is.&$total
. This way, modifying the value of $total
DOES HAVE an external effect, the original variable's value changes.As @Mytskine pointed out probably the best in-depth explanation is the RFC for closures. (Upvote him for this.)
You need to compile the bibtex file.
Suppose you have article.tex
and article.bib
. You need to run:
latex article.tex
(this will generate a document with question marks in place of unknown references)bibtex article
(this will parse all the .bib files that were included in the article and generate metainformation regarding references)latex article.tex
(this will generate document with all the references in the correct places)latex article.tex
(just in case if adding references broke page numbering somewhere)The Separator
you are using is a UI component. You would be better using a simple String sep = ", "
.
We can use the formula method of aggregate
. The variables on the 'rhs' of ~
are the grouping variables while the .
represents all other variables in the 'df1' (from the example, we assume that we need the mean
for all the columns except the grouping), specify the dataset and the function (mean
).
aggregate(.~id1+id2, df1, mean)
Or we can use summarise_each
from dplyr
after grouping (group_by
)
library(dplyr)
df1 %>%
group_by(id1, id2) %>%
summarise_each(funs(mean))
Or using summarise
with across
(dplyr
devel version - ‘0.8.99.9000’
)
df1 %>%
group_by(id1, id2) %>%
summarise(across(starts_with('val'), mean))
Or another option is data.table
. We convert the 'data.frame' to 'data.table' (setDT(df1)
, grouped by 'id1' and 'id2', we loop through the subset of data.table (.SD
) and get the mean
.
library(data.table)
setDT(df1)[, lapply(.SD, mean), by = .(id1, id2)]
df1 <- structure(list(id1 = c("a", "a", "a", "a", "b", "b",
"b", "b"
), id2 = c("x", "x", "y", "y", "x", "y", "x", "y"),
val1 = c(1L,
2L, 3L, 4L, 1L, 4L, 3L, 2L), val2 = c(9L, 4L, 5L, 9L, 7L, 4L,
9L, 8L)), .Names = c("id1", "id2", "val1", "val2"),
class = "data.frame", row.names = c("1",
"2", "3", "4", "5", "6", "7", "8"))
If you have a source image or canvas element and your 400x400 canvas you want to draw into you can use the drawImage method to achieve zooming.
So for example, the full view might be like this
ctx.drawImage(img, 0, 0, img.width, img.height, 0, 0, canvas.width, canvas.height);
And a zoomed view might be like this
ctx.drawImage(img, img.width / 4, img.height / 4, img.width / 2, img.height / 2, 0, 0, canvas.width, canvas.height);
The first parameter to drawImage is the image element or canvas element to draw, the next 4 are the x, y, width and height to sample from the source and the last 4 parameters are the x, y, width and height of the region to draw in the canvas. It will then handle the scaling for you.
You would just need to pick the width and height for the source sample based on the zoom level and the x and y based on where the mouse is clicked minus half the calculated width and height (but you will need to ensure the rectangle isn't out of bounds).
While probably not as clean looking as the IConvertible
approach, you could always use the straightforward checking typeof(T)
to return a T
:
public static T ReturnType<T>(string stringValue)
{
if (typeof(T) == typeof(int))
return (T)(object)1;
else if (typeof(T) == typeof(FooBar))
return (T)(object)new FooBar(stringValue);
else
return default(T);
}
public class FooBar
{
public FooBar(string something)
{}
}

File sutest
#!/bin/bash
echo "uid is ${UID}"
echo "user is ${USER}"
echo "username is ${USERNAME}"
run it: `./sutest' gives me
uid is 500
user is stephenp
username is stephenp
but using sudo: sudo ./sutest
gives
uid is 0
user is root
username is stephenp
So you retain the original user name in $USERNAME when running as sudo. This leads to a solution similar to what others posted:
#!/bin/bash
sudo -u ${USERNAME} normal_command_1
root_command_1
root_command_2
sudo -u ${USERNAME} normal_command_2
# etc.
Just sudo to invoke your script in the first place, it will prompt for the password once.
I originally wrote this answer on Linux, which does have some differences with OS X
OS X (I'm testing this on Mountain Lion 10.8.3) has an environment variable SUDO_USER
when you're running sudo, which can be used in place of USERNAME
above, or to be more cross-platform the script could check to see if SUDO_USER is set and use it if so, or use USERNAME if that's set.
Changing the original script for OS X, it becomes...
#!/bin/bash
sudo -u ${SUDO_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${SUDO_USER} normal_command_2
# etc.
A first stab at making it cross-platform could be...
#!/bin/bash
#
# set "THE_USER" to SUDO_USER if that's set,
# else set it to USERNAME if THAT is set,
# else set it to the string "unknown"
# should probably then test to see if it's "unknown"
#
THE_USER=${SUDO_USER:-${USERNAME:-unknown}}
sudo -u ${THE_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${THE_USER} normal_command_2
# etc.

This answer has a code example, which implements the algorithm described in the paper Practical In-Place Merging by Bing-Chao Huang and Michael A. Langston. I have to admit that I do not understand the details, but the given complexity of the merge step is O(n).
From a practical perspective, there is evidence that pure in-place implementations are not performing better in real world scenarios. For example, the C++ standard defines std::inplace_merge, which is as the name implies an in-place merge operation.
Assuming that C++ libraries are typically very well optimized, it is interesting to see how it is implemented:
The implementation delegates to __inplace_merge, which dodges the problem by trying to allocate a temporary buffer:
typedef _Temporary_buffer<_BidirectionalIterator, _ValueType> _TmpBuf;
_TmpBuf __buf(__first, __len1 + __len2);
if (__buf.begin() == 0)
std::__merge_without_buffer
(__first, __middle, __last, __len1, __len2, __comp);
else
std::__merge_adaptive
(__first, __middle, __last, __len1, __len2, __buf.begin(),
_DistanceType(__buf.size()), __comp);
Otherwise, it falls back to an implementation (__merge_without_buffer), which requires no extra memory, but no longer runs in O(n) time.
Looks similar. It delegates to a function, which also tries to allocate a buffer. Depending on whether it got enough elements, it will choose the implementation. The constant-memory fallback function is called __buffered_inplace_merge.
Maybe even the fallback is still O(n) time, but the point is that they do not use the implementation if temporary memory is available.
Note that the C++ standard explicitly gives implementations the freedom to choose this approach by lowering the required complexity from O(n) to O(N log N):
Complexity: Exactly N-1 comparisons if enough additional memory is available. If the memory is insufficient, O(N log N) comparisons.
Of course, this cannot be taken as a proof that constant space in-place merges in O(n) time should never be used. On the other hand, if it would be faster, the optimized C++ libraries would probably switch to that type of implementation.

Old question, but here's a fairly clean way to create a nullable parameter:
new SqlParameter("@note", (object) request.Body ?? DBNull.Value);
If request.Body has a value, then it's value is used. If it's null, then DbNull.Value is used.

If the compiler is smart enough to figure out the type from the context, then so are you. You don't have to have it written down right there at declaration. And intellisense makes that even less necessary.

If you really want to avoid touching this code, you can use Powermockito (PowerMock for Mockito).

The CSS by Paulius Marciukaitis worked nicely for my Genesis theme, here's what how I further modified it for my requirement:
@media only screen and (max-width: 480px) {
.entry {
background-color: #fff;
margin-bottom: 0;
padding: 10px 8px;
}
This works:
sc.exe config "[servicename]" obj= "[.\username]" password= "[password]"
Where each of the [bracketed] items are replaced with the true arguments. (Keep the quotes, but don't keep the brackets.)
Just keep in mind that:
obj= "foo"
is correct; obj="foo"
is not.I generally like to merge master
into the development
first so that if there are any conflicts, I can resolve in the development
branch itself and my master
remains clean.
(on branch development)$ git merge master
(resolve any merge conflicts if there are any)
git checkout master
git merge development (there won't be any conflicts now)
There isn't much of a difference in the two approaches, but I have noticed sometimes that I don't want to merge the branch into master
yet, after merging them, or that there is still more work to be done before these can be merged, so I tend to leave master
untouched until final stuff.
EDIT: From comments
If you want to keep track of who did the merge and when, you can use --no-ff
flag while merging to do so. This is generally useful only when merging development
into the master
(last step), because you might need to merge master
into development
(first step) multiple times in your workflow, and creating a commit node for these might not be very useful.
git merge --no-ff development
According to my Scenario, I did "use CASE statement in WHERE IN clause" like following
@AdjType varchar(20) = 'Value',
@Base varchar(20) = 'Common'
where
(select CASE WHEN SA.IsPersentage = 0 THEN 'Value'
WHEN SA.IsPersentage = 1 THEN 'Presentage' END) Like @AdjType
and (Select CASE WHEN SA.IsDependOnBasicSalary = 0 THEN 'Common'
WHEN SA.IsDependOnBasicSalary = 1 THEN 'Basic Salary' END) like @Base
In order to read or write to the standard input/output streams you need to include it.
int main( int argc, char * argv[] )
{
std::cout << "Hello World!" << std::endl;
return 0;
}
That program will not compile unless you add #include <iostream>
The second line isn't necessary
using namespace std;
What that does is tell the compiler that symbol names defined in the std
namespace are to be brought into your program's scope, so you can omit the namespace qualifier, and write for example
#include <iostream>
using namespace std;
int main( int argc, char * argv[] )
{
cout << "Hello World!" << endl;
return 0;
}
Notice you no longer need to refer to the output stream with the fully qualified name std::cout
and can use the shorter name cout
.
I personally don't like bringing in all symbols in the namespace of a header file... I'll individually select the symbols I want to be shorter... so I would do this:
#include <iostream>
using std::cout;
using std::endl;
int main( int argc, char * argv[] )
{
cout << "Hello World!" << endl;
return 0;
}
But that is a matter of personal preference.

ISLE (InstallShield Limited Edition) is the "replacement" of the Visual Studio Setup and Deploy project, but many users think Microsoft took wrong step with removing .vdproj support from Visual Studio 2012 (and later ones) and supporting third-party company software.
Many people asked for returning it back (Bring back the basic setup and deployment project type Visual Studio Installer), but Microsoft is deaf to our voices... really sad.
As WiX is really complicated, I think it is worth to try some free installation systems - NSIS or Inno Setup. Both are scriptable and easy to learn - but powerful as original SADP.
I have created a really nice Visual Studio extension for NSIS and Inno Setup with many features (intellisense, syntax highlighting, navigation bars, compilation directly from Visual Studio, etc.). You can try it at www.visual-installer.com (sorry for self promo :)
Download Inno Setup (jrsoftware.org/isdl.php) or NSIS (nsis.sourceforge.net/Download) and install V&I (unsigned-softworks.sk/visual-installer/downloads.html).
All installers are simple Next/Next/Next...
In Visual Studio, select menu File -> New -> Project, choose NSISProject or Inno Setup, and a new project will be created (with full sources).
Try destroying the datatable with bDestroy:true like this:
$("#ajaxchange").click(function(){
var campaign_id = $("#campaigns_id").val();
var fromDate = $("#from").val();
var toDate = $("#to").val();
var url = 'http://domain.com/account/campaign/ajaxrefreshgrid?format=html';
$.post(url, { campaignId: campaign_id, fromdate: fromDate, todate: toDate},
function( data ) {
$("#ajaxresponse").html(data);
oTable6 = $('#rankings').dataTable( {"bDestroy":true,
"sDom":'t<"bottom"filp><"clear">',
"bAutoWidth": false,
"sPaginationType": "full_numbers",
"aoColumns": [
{ "bSortable": false, "sWidth": "10px" },
null,
null,
null,
null,
null,
null,
null,
null,
null,
null,
null
]
}
);
});
});
bDestroy: true will first destroy and datatable instance associated with that selector before reinitializing a new one.

Move import sys
outside of the try
-except
block:
import sys
try:
# ...
except ImportError:
# ...
If any of the imports before the import sys
line fails, the rest of the block is not executed, and sys
is never imported. Instead, execution jumps to the exception handling block, where you then try to access a non-existing name.
sys
is a built-in module anyway, it is always present as it holds the data structures to track imports; if importing sys
fails, you have bigger problems on your hand (as that would indicate that all module importing is broken).
Here's how to determine a local user:
public bool IsLocalUser()
{
return windowsIdentity.AuthenticationType == "NTLM";
}
You should not use NTLM anymore at all. It is so old, and so bad, that Microsoft's Application Verifier (which is used to catch common programming mistakes) will throw a warning if it detects you using NTLM.
Here's a chapter from the Application Verifier documentation about why they have a test if someone is mistakenly using NTLM:
Why the NTLM Plug-in is Needed
NTLM is an outdated authentication protocol with flaws that potentially compromise the security of applications and the operating system. The most important shortcoming is the lack of server authentication, which could allow an attacker to trick users into connecting to a spoofed server. As a corollary of missing server authentication, applications using NTLM can also be vulnerable to a type of attack known as a “reflection” attack. This latter allows an attacker to hijack a user’s authentication conversation to a legitimate server and use it to authenticate the attacker to the user’s computer. NTLM’s vulnerabilities and ways of exploiting them are the target of increasing research activity in the security community.
Although Kerberos has been available for many years many applications are still written to use NTLM only. This needlessly reduces the security of applications. Kerberos cannot however replace NTLM in all scenarios – principally those where a client needs to authenticate to systems that are not joined to a domain (a home network perhaps being the most common of these). The Negotiate security package allows a backwards-compatible compromise that uses Kerberos whenever possible and only reverts to NTLM when there is no other option. Switching code to use Negotiate instead of NTLM will significantly increase the security for our customers while introducing few or no application compatibilities. Negotiate by itself is not a silver bullet – there are cases where an attacker can force downgrade to NTLM but these are significantly more difficult to exploit. However, one immediate improvement is that applications written to use Negotiate correctly are automatically immune to NTLM reflection attacks.
By way of a final word of caution against use of NTLM: in future versions of Windows it will be possible to disable the use of NTLM at the operating system. If applications have a hard dependency on NTLM they will simply fail to authenticate when NTLM is disabled.
How the Plug-in Works
The Verifier plug detects the following errors:
The NTLM package is directly specified in the call to AcquireCredentialsHandle (or higher level wrapper API).
The target name in the call to InitializeSecurityContext is NULL.
The target name in the call to InitializeSecurityContext is not a properly-formed SPN, UPN or NetBIOS-style domain name.
The latter two cases will force Negotiate to fall back to NTLM either directly (the first case) or indirectly (the domain controller will return a “principal not found” error in the second case causing Negotiate to fall back).
The plug-in also logs warnings when it detects downgrades to NTLM; for example, when an SPN is not found by the Domain Controller. These are only logged as warnings since they are often legitimate cases – for example, when authenticating to a system that is not domain-joined.
NTLM Stops
5000 – Application Has Explicitly Selected NTLM Package
Severity – Error
The application or subsystem explicitly selects NTLM instead of Negotiate in the call to AcquireCredentialsHandle. Even though it may be possible for the client and server to authenticate using Kerberos this is prevented by the explicit selection of NTLM.
How to Fix this Error
The fix for this error is to select the Negotiate package in place of NTLM. How this is done will depend on the particular Network subsystem being used by the client or server. Some examples are given below. You should consult the documentation on the particular library or API set that you are using.
APIs(parameter) Used by Application Incorrect Value Correct Value ===================================== =============== ======================== AcquireCredentialsHandle (pszPackage) “NTLM” NEGOSSP_NAME “Negotiate”
Updating to use tibble()
You can pass a named vector of length greater than 1 to the by
argument of left_join()
:
library(dplyr)
d1 <- tibble(
x = letters[1:3],
y = LETTERS[1:3],
a = rnorm(3)
)
d2 <- tibble(
x2 = letters[3:1],
y2 = LETTERS[3:1],
b = rnorm(3)
)
left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))
with prototype and without space :
String.prototype.trimToLength = function (trimLenght) {
return this.length > trimLenght ? this.substring(0, trimLenght - 3) + '...' : this
};
This is a quite confusing way of using Apache configuration directives.
Technically, the first bit is equivalent to
Allow From All
This is because Order Deny,Allow
makes the Deny directive evaluated before the Allow Directives.
In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.
Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.
The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.
Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.
It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):
#
# The following lines prevent .htaccess and .htpasswd files from being
# viewed by Web clients.
#
<Files ~ "^\.ht">
Order allow,deny
Deny from all
Satisfy all
</Files>
which forbids access to any file beginning by ".ht".
The equivalent Apache 2.4 configuration should look like:
<Files ~ "^\.ht">
Require all denied
</Files>
Try this:
let jsonArr = [
{
"_id":"5078c3a803ff4197dc81fbfb",
"email":"[email protected]",
"image":"some_image_url",
"name":"Name 1"
},
{
"_id":"5078c3a803ff4197dc81fbfc",
"email":"[email protected]",
"image":"some_image_url",
"name":"Name 2"
}
]
let idModified = jsonArr.map(
obj => {
return {
"id" : obj._id,
"email":obj.email,
"image":obj.image,
"name":obj.name
}
}
);
console.log(idModified);
Try this
IsBodyHtml = false,
BodyEncoding = Encoding.UTF8,
BodyTransferEncoding = System.Net.Mime.TransferEncoding.EightBit
If you wish to stick to using \r\n

BSDs have stat
with different options from the GNU coreutils one, but similar capabilities.
stat -f %z <file name>
This works on macOS (tested on 10.12), FreeBSD, NetBSD and OpenBSD.
Add a reference to the Microsoft.VisualBasic (yes, it says VisualBasic but it works in C# just as well - remember that at the end it is all just IL).
Use the Microsoft.VisualBasic.FileIO.TextFieldParser
class to parse CSV file Here is the sample code:
Dim parser As TextFieldParser = New TextFieldParser("C:\mar0112.csv")
parser.TextFieldType = FieldType.Delimited
parser.SetDelimiters(",")
While Not parser.EndOfData
'Processing row
Dim fields() As String = parser.ReadFields
For Each field As String In fields
'TODO: Process field
Next
parser.Close()
End While

Clyde's solution works, but it is a broadcast, which I am pretty sure will be less efficient than calling a method directly. I could be mistaken, but I think the broadcasts are meant more for inter-application communication.
I'm assuming you already know how to bind a service with an Activity. I do something sort of like the code below to handle this kind of problem:
class MyService extends Service {
MyFragment mMyFragment = null;
MyFragment mMyOtherFragment = null;
private void networkLoop() {
...
//received new data for list.
if(myFragment != null)
myFragment.updateList();
}
...
//received new data for textView
if(myFragment !=null)
myFragment.updateText();
...
//received new data for textView
if(myOtherFragment !=null)
myOtherFragment.updateSomething();
...
}
}
class MyFragment extends Fragment {
public void onResume() {
super.onResume()
//Assuming your activity bound to your service
getActivity().mMyService.mMyFragment=this;
}
public void onPause() {
super.onPause()
//Assuming your activity bound to your service
getActivity().mMyService.mMyFragment=null;
}
public void updateList() {
runOnUiThread(new Runnable() {
public void run() {
//Update the list.
}
});
}
public void updateText() {
//as above
}
}
class MyOtherFragment extends Fragment {
public void onResume() {
super.onResume()
//Assuming your activity bound to your service
getActivity().mMyService.mMyOtherFragment=this;
}
public void onPause() {
super.onPause()
//Assuming your activity bound to your service
getActivity().mMyService.mMyOtherFragment=null;
}
public void updateSomething() {//etc... }
}
I left out bits for thread safety, which is essential. Make sure to use locks or something like that when checking and using or changing the fragment references on the service.
First of all, do a backup of your needed databases with mysqldump
Note: If you want to restore later, just backup your relevant databases, and not the WHOLE, because the whole database might actually be the reason you need to purge and reinstall).
In total, do this:
sudo service mysql stop #or mysqld
sudo killall -9 mysql
sudo killall -9 mysqld
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo deluser -f mysql
sudo rm -rf /var/lib/mysql
sudo apt-get purge mysql-server-core-5.7
sudo apt-get purge mysql-client-core-5.7
sudo rm -rf /var/log/mysql
sudo rm -rf /etc/mysql
All above commands in single line (just copy and paste):
sudo service mysql stop && sudo killall -9 mysql && sudo killall -9 mysqld && sudo apt-get remove --purge mysql-server mysql-client mysql-common && sudo apt-get autoremove && sudo apt-get autoclean && sudo deluser mysql && sudo rm -rf /var/lib/mysql && sudo apt-get purge mysql-server-core-5.7 && sudo apt-get purge mysql-client-core-5.7 && sudo rm -rf /var/log/mysql && sudo rm -rf /etc/mysql
You can remove the filename from GetModuleFileName()
with more elegant way:
TCHAR fullPath[MAX_PATH];
TCHAR driveLetter[3];
TCHAR directory[MAX_PATH];
TCHAR FinalPath[MAX_PATH];
GetModuleFileName(NULL, fullPath, MAX_PATH);
_splitpath(fullPath, driveLetter, directory, NULL, NULL);
sprintf(FinalPath, "%s%s",driveLetter, directory);
Hope it helps!
The error code 0x800A03EC
(or -2146827284) means NAME_NOT_FOUND; in other words, you've asked for something, and Excel can't find it.
This is a generic code, which can apply to lots of things it can't find e.g. using properties which aren't valid at that time like PivotItem.SourceNameStandard
throws this when a PivotItem doesn't have a filter applied. Worksheets["BLAHBLAH"]
throws this, when the sheet doesn't exist etc. In general, you are asking for something with a specific name and it doesn't exist. As for why, that will taking some digging on your part.
Check your sheet definitely does have the Range you are asking for, or that the .CellName
is definitely giving back the name of the range you are asking for.
I needed an object from the query string, and I hate lots of code. It may not be the most robust in the universe, but it's just a few lines of code.
var q = {};
location.href.split('?')[1].split('&').forEach(function(i){
q[i.split('=')[0]]=i.split('=')[1];
});
A URL like this.htm?hello=world&foo=bar
will create:
{hello:'world', foo:'bar'}
Some of the brokerage firms like TDAmeritrade have APIs you can use to get streaming data from their servers:
http://www.tdameritrade.com/tradingtools/partnertools/api_dev.html
That should work. Better if you pass a function to val
:
$('#replyBox').val(function(i, text) {
return text + quote;
});
This way you avoid searching the element and calling val
twice.
All the other solutions here are OS dependent. An independent solution for any OS uses socket.io as follows.
package.json
has two scripts:
"scripts": {
"start": "node server.js",
"stop": "node server.stop.js"
}
const express = require('express');
const app = express();
const server = http.createServer(app);
server.listen(80, () => {
console.log('HTTP server listening on port 80');
});
// Now for the socket.io stuff - NOTE THIS IS A RESTFUL HTTP SERVER
// We are only using socket.io here to respond to the npmStop signal
// To support IPC (Inter Process Communication) AKA RPC (Remote P.C.)
const io = require('socket.io')(server);
io.on('connection', (socketServer) => {
socketServer.on('npmStop', () => {
process.exit(0);
});
});
const io = require('socket.io-client');
const socketClient = io.connect('http://localhost'); // Specify port if your express server is not using default port 80
socketClient.on('connect', () => {
socketClient.emit('npmStop');
setTimeout(() => {
process.exit(0);
}, 1000);
});
npm start
(to start your server as usual)
npm stop
(this will now stop your running server)
The above code has not been tested (it is a cut down version of my code, my code does work) but hopefully it works as is. Either way, it provides the general direction to take if you want to use socket.io to stop your server.
I don't think that any shortcut is remaining for me to mention so let me mention a shortcut that I would love Visual Studio to have :-) One shortcut that I really miss and that is present in Eclipse is "Open Resource" (Ctrl + Shift + S) which allows you to type in a file name and the IDE displays the files matching it. Really useful when you are working with bid code bases!
If it's off of a web page, I recommend generating a signal of some kind (dropping a file in a directory, perhaps) and having a cron job pick up the work that needs to be done. Otherwise, we're likely to get into the territory of using pcntl_fork()
and exec()
from inside an Apache process, and that's just bad mojo.
For WINDOWS (shell) users with Notepad++ (checked with v6.8.3) you can correct the specific file using the option - Edit -> EOL conversion -> Unix/OSX format
And save your file again.
Edit: still works in v7.5.1 (Aug 29 2017)
No one will ever see this, but it's good to bring back recursion and arrow functions once in a while (pun gloriously intended)
String.prototype.occurrencesOf = function(s, i) {
return (n => (n === -1) ? 0 : 1 + this.occurrencesOf(s, n + 1))(this.indexOf(s, (i || 0)));
};
=IF(CR<=10, "RED", if(CR<50, "YELLOW", if(CR<101, "GREEN")))
CR = ColRow (Cell)
This is an example. In this example when value in Cell is less then or equal to 10 then RED word will appear on that cell. In the same manner other if conditions are true if first if is false.
This should not happen. Can you try doing this? Use the system properties and set the property as below:
Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", "10.101.3.229");
And if you have a port associated, then set this as well.
properties.setProperty("mail.smtp.port", "8080");
Use the substring method of the String class :
String removeCurrency=amount.getText().toString().substring(3);
The way that I found to resolve this was to use AddJsonFile in a builder at Startup (which allows it to find the configuration stored in the appsettings.json file) and then use that to set a private _config variable
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
.AddEnvironmentVariables();
_config = builder.Build();
}
And then I could set the configuration string as follows:
var connectionString = _config.GetConnectionString("DbContextSettings:ConnectionString");
This is on dotnet core 1.1
You can pass a name to the unknown key and then write your types:
type StuffBody = {
[key: string]: string;
};
Now you can use it in your type checking:
let stuff: StuffBody = {};
But for FlowType there is no need to have name:
type StuffBody = {
[string]: string,
};
Sorting by C and D needs to be put into number form for the corresponding column, ie 3 and 4, respectively. Eg Order By 2 asc")
For me I had to put the whole interval in single quotes not just the value of the interval.
select id,
title,
created_at + interval '1 day' * claim_window as deadline from projects
Instead of
select id,
title,
created_at + interval '1' day * claim_window as deadline from projects
import datetime
def daterange(start, stop, step_days=1):
current = start
step = datetime.timedelta(step_days)
if step_days > 0:
while current < stop:
yield current
current += step
elif step_days < 0:
while current > stop:
yield current
current += step
else:
raise ValueError("daterange() step_days argument must not be zero")
if __name__ == "__main__":
from pprint import pprint as pp
lo = datetime.date(2008, 12, 27)
hi = datetime.date(2009, 1, 5)
pp(list(daterange(lo, hi)))
pp(list(daterange(hi, lo, -1)))
pp(list(daterange(lo, hi, 7)))
pp(list(daterange(hi, lo, -7)))
assert not list(daterange(lo, hi, -1))
assert not list(daterange(hi, lo))
assert not list(daterange(lo, hi, -7))
assert not list(daterange(hi, lo, 7))
In case of MAC users, go to Terminal and do the following
lsof -i :8080 //returns the PID (process id) that runs on port 8080
kill 1234 //kill the process using PID (used dummy PID here)
lsof -i :8443
kill 4321
8080 is HTTP port and 8443 is HTTPS port, by default.
You don't need to create a user-defined setting. The built-in setting "Preprocessor Macros" works just fine. alt text http://idisk.mac.com/cdespinosa/Public/Picture%204.png
If you have multiple targets or projects that use the same prefix file, use Preprocessor Macros Not Used In Precompiled Headers instead, so differences in your macro definition don't trigger an unnecessary extra set of precompiled headers.
Exactly what they said, it will work.
In the parent element stablish a max-height.
I'm taking sandeep example and adding the max-height and if required you can add max-width property. The text will stay where It should stay (If possible, in some cases you will need to change some values to make it stay in there)
span{

}
p{
margin:100px;
float:left;
position:relative;
cursor:pointer;
max-height: 10px;
}
p:hover span{
display:block;
}
max-height in the p paragraph, second to last one, last line.
Test it before rating it useless.
You have to actively choose to install MSYS to get the make.exe. So you should always have at least (the native) mingw32-make.exe if MinGW was installed properly. And if you installed MSYS you will have make.exe (in the MSYS subfolder probably).
Note that many projects require first creating a makefile (e.g. using a configure script or automake .am file) and it is this step that requires MSYS or cygwin. Makes you wonder why they bothered to distribute the native make at all.
Once you have the makefile, it is unclear if the native executable requires a different path separator than the MSYS make (forward slashes vs backward slashes). Any autogenerated makefile is likely to have unix-style paths, assuming the native make can handle those, the compiled output should be the same.
You are not giving us the whole picture.
javascript:alert(parseFloat(1).toFixed(2))

Raw queries are more vulnerable to SQL Injection. I will suggest using query()
method instead.
public boolean Exists(String searchItem) {
String[] columns = { COLUMN_NAME };
String selection = COLUMN_NAME + " =?";
String[] selectionArgs = { searchItem };
String limit = "1";
Cursor cursor = db.query(TABLE_NAME, columns, selection, selectionArgs, null, null, null, limit);
boolean exists = (cursor.getCount() > 0);
cursor.close();
return exists;
}

Another solution is just using not
to get the opposite negation:
<h2 th:if="${potentially_complex_expression}">Hello!</h2>
<span class="xxx" th:if="${not potentially_complex_expression}">Something else</span>
As explained in the documentation, it's the same thing as using th:unless
. As other answers have explained:
Also,
th:if
has an inverse attribute,th:unless
, which we could have used in the previous example instead of using a not inside the OGNL expression
Using not
also works, but IMHO it is more readable to use th:unless
instead of negating the condition with not
.
The above code works well but if you want to navigate from an NSObject
class, where you can not use self.present
:
let storyBoard = UIStoryboard(name:"Main", bundle: nil)
if let conVC = storyBoard.instantiateViewController(withIdentifier: "SoundViewController") as? SoundViewController,
let navController = UIApplication.shared.keyWindow?.rootViewController as? UINavigationController {
navController.pushViewController(conVC, animated: true)
}
In addition what others mentioned here, note that combining the Application.DispatcherUnhandledException
(and its similars) with
<configuration>
<runtime>
<legacyUnhandledExceptionPolicy enabled="1" />
</runtime>
</configuration>
in the app.config
will prevent your secondary threads exception from shutting down the application.
In workbench 6.0 Connect to any of the database. You will see two tabs.
1.Management
2. Schemas
By default Schemas
tab is selected.
Select Management
tab
then select Data Export
.
You will get list of all databases.
select the desired database and and the file name and ther options you wish and start export.
You are done with backup.
With ref
you can write:
static public void DoSomething(ref TestRef t)
{
t = new TestRef();
}
And t will be changed after the method has completed.
This behavior is explicitly documented in String.split(String regex)
(emphasis mine):
This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
If you want those trailing empty strings included, you need to use String.split(String regex, int limit)
with a negative value for the second parameter (limit
):
String[] array = values.split("\\|", -1);

You can't actually render markup inside a textarea.
But, you can fake it by carefully positioning a div behind the textarea and adding your highlight markup there.
JavaScript takes care of syncing the content and scroll position.
var $container = $('.container');
var $backdrop = $('.backdrop');
var $highlights = $('.highlights');
var $textarea = $('textarea');
var $toggle = $('button');
var ua = window.navigator.userAgent.toLowerCase();
var isIE = !!ua.match(/msie|trident\/7|edge/);
var isWinPhone = ua.indexOf('windows phone') !== -1;
var isIOS = !isWinPhone && !!ua.match(/ipad|iphone|ipod/);
function applyHighlights(text) {
text = text
.replace(/\n$/g, '\n\n')
.replace(/[A-Z].*?\b/g, '<mark>$&</mark>');
if (isIE) {
// IE wraps whitespace differently in a div vs textarea, this fixes it
text = text.replace(/ /g, ' <wbr>');
}
return text;
}
function handleInput() {
var text = $textarea.val();
var highlightedText = applyHighlights(text);
$highlights.html(highlightedText);
}
function handleScroll() {
var scrollTop = $textarea.scrollTop();
$backdrop.scrollTop(scrollTop);
var scrollLeft = $textarea.scrollLeft();
$backdrop.scrollLeft(scrollLeft);
}
function fixIOS() {
$highlights.css({
'padding-left': '+=3px',
'padding-right': '+=3px'
});
}
function bindEvents() {
$textarea.on({
'input': handleInput,
'scroll': handleScroll
});
}
if (isIOS) {
fixIOS();
}
bindEvents();
handleInput();

If you are trying to "Submit and Reset" the the "form" with one Button click, Try this!
Here I have used jQuery function, it can be done by simple JavaScript also...
<form id="form_data">
<input type="anything" name="anything" />
<input type="anything" name="anything" />
<!-- Save and Reset button -->
<button type="button" id="btn_submit">Save</button>
<button type="reset" id="btn_reset" style="display: none;"></button>
</form>
<script type="text/javascript">
$(function(){
$('#btn_submit').click(function(){
// Do what ever you want
$('#btn_reset').click(); // Clicking reset button
});
});
</script>
This is because in this case the char
type is signed on your system*. When this happens, the data gets sign-extended during the default conversions while passing the data to the function with variable number of arguments. Since 212 is greater than 0x80, it's treated as negative, %u
interprets the number as a large positive number:
212 = 0xD4
When it is sign-extended, FF
s are pre-pended to your number, so it becomes
0xFFFFFFD4 = 4294967252
which is the number that gets printed.
Note that this behavior is specific to your implementation. According to C99 specification, all char
types are promoted to (signed) int
, because an int
can represent all values of a char
, signed or unsigned:
6.1.1.2: If an
int
can represent all values of the original type, the value is converted to anint
; otherwise, it is converted to anunsigned int
.
This results in passing an int
to a format specifier %u
, which expects an unsigned int
.
To avoid undefined behavior in your program, add explicit type casts as follows:
unsigned char ch = (unsigned char)212;
printf("%u", (unsigned int)ch);
char
up to the implementation. See this question for more details.
Alright, so I ended up going with the code I wrote here, on my website link is dead, view on archive.org (also available on GitHub). I can use it in the following fashion:
from filelock import FileLock
with FileLock("myfile.txt.lock"):
print("Lock acquired.")
with open("myfile.txt"):
# work with the file as it is now locked
There's a ton of answers already here, but I stumbled upon a great article about how to use Razor with email templating. Razor was pushed with ASP.NET MVC 3, but MVC is not required to use Razor. This is pretty slick processing of doing email templates
As the article identifies, "The best thing of Razor is that unlike its predecessor(webforms) it is not tied with the web environment, we can easily host it outside the web and use it as template engine for various purpose. "

Adding to above discussion this only represents Happy scenarios. probably you will not be able to log the response if an Error comes .
In this case plus all the cases above you must override DefaultResponseErrorHandler and set it like below
restTemplate.setErrorHandler(new DefaultResponseErrorHandlerImpl());
Private Sub BagQty_KeyPress(sender As Object, e As KeyPressEventArgs) Handles BagQty.KeyPress
Select e.KeyChar
Case Microsoft.VisualBasic.ChrW(Keys.Return)
PurchaseTotal.Text = Val(ActualRate.Text) * Val(BagQty.Text)
End Select
End Sub
You can either have the newly inserted ID being output to the SSMS console like this:
INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')
You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar()
(instead of .ExecuteNonQuery()
) to read the resulting ID
back.
Or if you need to capture the newly inserted ID
inside T-SQL (e.g. for later further processing), you need to create a table variable:
DECLARE @OutputTbl TABLE (ID INT)
INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')
This way, you can put multiple values into @OutputTbl
and do further processing on those. You could also use a "regular" temporary table (#temp
) or even a "real" persistent table as your "output target" here.
Angular UI library has built-in directive ui-if for condition in template/Views upto angular ui 1.1.4
Example: Support in Angular UI upto ui 1.1.4
<div ui-if="array.length>0"></div>
ng-if available in all the angular version after 1.1.4
<div ng-if="array.length>0"></div>
if you have any data in array variable then only the div will appear
another way is, you assign a column value for a given row based on the index position of a row, the index position always starts with zero, and the last index position is the length of the dataframe:
df["COL_NAME"].iloc[0]=x
var obj = [
{"name": "Afghanistan", "code": "AF"},
{"name": "Åland Islands", "code": "AX"},
{"name": "Albania", "code": "AL"},
{"name": "Algeria", "code": "DZ"}
];
// the code you're looking for
var needle = 'AL';
// iterate over each element in the array
for (var i = 0; i < obj.length; i++){
// look for the entry with a matching `code` value
if (obj[i].code == needle){
// we found it
// obj[i].name is the matched result
}
}
I also use Stefan Petre’s http://www.eyecon.ro/bootstrap-datepicker and it does not work with Bootstrap 3 without modification. Note that http://eternicode.github.io/bootstrap-datepicker/ is a fork of Stefan Petre's code.
You have to change your markup (the sample markup will not work) to use the new CSS and form grid layout in Bootstrap 3. Also, you have to modify some CSS and JavaScript in the actual bootstrap-datepicker implementation.
Here is my solution:
<div class="form-group row">
<div class="col-xs-8">
<label class="control-label">My Label</label>
<div class="input-group date" id="dp3" data-date="12-02-2012" data-date-format="mm-dd-yyyy">
<input class="form-control" type="text" readonly="" value="12-02-2012">
<span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
</div>
</div>
</div>
CSS changes in datepicker.css on lines 176-177:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 34:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon') : false;
UPDATE
Using the newer code from http://eternicode.github.io/bootstrap-datepicker/ the changes are as follows:
CSS changes in datepicker.css on lines 446-447:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 46:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon, .btn') : false;
Finally, the JavaScript to enable the datepicker (with some options):
$(".input-group.date").datepicker({ autoclose: true, todayHighlight: true });
Tested with Bootstrap 3.0 and JQuery 1.9.1. Note that this fork is better to use than the other as it is more feature rich, has localization support and auto-positions the datepicker based on the control position and window size, avoiding the picker going off the screen which was a problem with the older version.
In the interest of actually putting a working solution to this question:
SELECT ... WHERE `myDateColumn` >= DATE(DATE_FORMAT(NOW(),'%Y-%m-%d'));
Obviously, you could change the NOW() function to any date or variable you want.
this is how I implemented the same in c++.
#include <iostream>
#include <cstring>
using namespace std;
int leng;
char ch;
string str, cpy;
int main() {
cout << "Enter a string: ";
getline(cin, str);
leng = str.length();
cout << endl << "Enter the character to delete: ";
cin >> ch;
for (int i=0; i<leng; i++) {
if (str[i] != ch)
cpy += str[i];
}
cout << endl << "String after removal: " << cpy;
return 0;
}
Not the catchiest name for an operator, but PHP 7 brings in the rather handy null coalesce so I thought I'd share an example.
In PHP 5, we already have a ternary operator, which tests a value, and then returns the second element if that returns true and the third if it doesn't:
echo $count ? $count : 10; // outputs 10
There is also a shorthand for that which allows you to skip the second element if it's the same as the first one: echo $count ?: 10; // also outputs 10
In PHP 7 we additionally get the ?? operator which rather than indicating extreme confusion which is how I would usually use two question marks together instead allows us to chain together a string of values. Reading from left to right, the first value which exists and is not null is the value that will be returned.
// $a is not set
$b = 16;
echo $a ?? 2; // outputs 2
echo $a ?? $b ?? 7; // outputs 16
This construct is useful for giving priority to one or more values coming perhaps from user input or existing configuration, and safely falling back on a given default if that configuration is missing. It's kind of a small feature but it's one that I know I'll be using as soon as my applications upgrade to PHP 7.
In our case problem occured due to availability cluster configuration. To solve this issue we had to set MultiSubnetFailover
to True in the connection string.

The API of java.io.File
only supports getting the last modified time. And the Internet is very quiet on this topic as well.
Unless I missed something significant, the Java library as is (up to but not yet including Java 7) does not include this capability. So if you were desperate for this, one solution would be to write some C(++) code to call system routines and call it using JNI. Most of this work seems to be already done for you in a library called JNA, though.
You may still need to do a little OS specific coding in Java for this, though, as you'll probably not find the same system calls available in Windows and Unix/Linux/BSD/OS X.
With python 3.6, these two lines return a list (may be empty)

Asked by many, The childs in list must not have width "match_parent" if you are looking for listview click only.
Even if you set the "Focusable" to false it wont work. Set the child's Width to wrap_content
<TextView
android:id="@+id/itemchild"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
...
You can do it via callback function.
$('a.button').click(function(){
if (condition == 'true'){
function1(someVariable, function() {
function2(someOtherVariable);
});
}
else {
doThis(someVariable);
}
});
function function1(param, callback) { ...do stuff callback(); }
the second argument in ROUNDUP, eg =ROUNDUP(12345.6789,3) refers to the negative of the base-10 column with that power of 10, that you want rounded up. eg 1000 = 10^3, so to round up to the next highest 1000, use ,-3)
=ROUNDUP(12345.6789,-4) = 20,000
=ROUNDUP(12345.6789,-3) = 13,000
=ROUNDUP(12345.6789,-2) = 12,400
=ROUNDUP(12345.6789,-1) = 12,350
=ROUNDUP(12345.6789,0) = 12,346
=ROUNDUP(12345.6789,1) = 12,345.7
=ROUNDUP(12345.6789,2) = 12,345.68
=ROUNDUP(12345.6789,3) = 12,345.679
So, to answer your question: if your value is in A1, use =ROUNDUP(A1,-1)
Your angular module needs to be initialized properly. The global object app
needs to be defined and initialized correctly to inject the service.
Please see below sample code for reference:
app.js
var app = angular.module('SampleApp',['ngRoute']); //You can inject the dependencies within the square bracket
app.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
$routeProvider
.when('/', {
templateUrl:"partials/login.html",
controller:"login"
});
$locationProvider
.html5Mode(true);
}]);
app.factory('getSettings', ['$http', '$q', function($http, $q) {
return {
//Code edited to create a function as when you require service it returns object by default so you can't return function directly. That's what understand...
getSetting: function (type) {
var q = $q.defer();
$http.get('models/settings.json').success(function (data) {
q.resolve(function() {
var settings = jQuery.parseJSON(data);
return settings[type];
});
});
return q.promise;
}
}
}]);
app.controller("globalControl", ['$scope','getSettings', function ($scope,getSettings) {
//Modified the function call for updated service
var loadSettings = getSettings.getSetting('global');
loadSettings.then(function(val) {
$scope.settings = val;
});
}]);
Sample HTML code should be like this:
<!DOCTYPE html>
<html>
<head lang="en">
<title>Sample Application</title>
</head>
<body ng-app="SampleApp" ng-controller="globalControl">
<div>
Your UI elements go here
</div>
<script src="app.js"></script>
</body>
</html>
Please note that the controller is not binding to an HTML tag but to the body tag. Also, please try to include your custom scripts at end of the HTML page as this is a standard practice to follow for performance reasons.
I hope this will solve your basic injection issue.

Besides the session cookie (which is kind of standard), I don't want to use extra cookies.
I found a solution which works for me when building a Single Page Web Application (SPA), with many AJAX requests. Note: I am using server side Java and client side JQuery, but no magic things so I think this principle can be implemented in all popular programming languages.
My solution without extra cookies is simple:
Store the CSRF token which is returned by the server after a succesful login in a global variable (if you want to use web storage instead of a global thats fine of course). Instruct JQuery to supply a X-CSRF-TOKEN header in each AJAX call.
The main "index" page contains this JavaScript snippet:
// Intialize global variable CSRF_TOKEN to empty sting.
// This variable is set after a succesful login
window.CSRF_TOKEN = '';
// the supplied callback to .ajaxSend() is called before an Ajax request is sent
$( document ).ajaxSend( function( event, jqXHR ) {
jqXHR.setRequestHeader('X-CSRF-TOKEN', window.CSRF_TOKEN);
});
On successul login, create a random (and long enough) CSRF token, store this in the server side session and return it to the client. Filter certain (sensitive) incoming requests by comparing the X-CSRF-TOKEN header value to the value stored in the session: these should match.
Sensitive AJAX calls (POST form-data and GET JSON-data), and the server side filter catching them, are under a /dataservice/* path. Login requests must not hit the filter, so these are on another path. Requests for HTML, CSS, JS and image resources are also not on the /dataservice/* path, thus not filtered. These contain nothing secret and can do no harm, so this is fine.
@WebFilter(urlPatterns = {"/dataservice/*"})
...
String sessionCSRFToken = req.getSession().getAttribute("CSRFToken") != null ? (String) req.getSession().getAttribute("CSRFToken") : null;
if (sessionCSRFToken == null || req.getHeader("X-CSRF-TOKEN") == null || !req.getHeader("X-CSRF-TOKEN").equals(sessionCSRFToken)) {
resp.sendError(401);
} else
chain.doFilter(request, response);
}

};
this.timer = pthis.setTimer();
this.clear = function(ref) { clearTimeout(ref.timer); ref.setTimer(); };
$(window.document).click( function(){pthis.clear.apply(pthis, [pthis])} );

How do you return a JSON object from a Java Servlet
response.setContentType("application/json");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
//create Json Object
JsonObject json = new JsonObject();
// put some value pairs into the JSON object .
json.addProperty("Mobile", 9999988888);
json.addProperty("Name", "ManojSarnaik");
// finally output the json string
out.print(json.toString());
To get this to work for me I had to drill down in the Python directory using the Python command prompt (on WIN10 from VS CODE). In my case it was in my "AppData\Local\Programs\Python\python35-32" directory. From there now I ran the command...
python -m pip install --upgrade pip
This worked and I'm good to go.
You can also refactor your code to use a generator. But this may not be a solution for all types of nested loops.
plf::nanotimer is a lightweight option for this, works in Windows, Linux, Mac and BSD etc. Has ~microsecond accuracy depending on OS:
#include "plf_nanotimer.h"
#include <iostream>
int main(int argc, char** argv)
{
plf::nanotimer timer;
timer.start()
// Do something here
double results = timer.get_elapsed_ns();
std::cout << "Timing: " << results << " nanoseconds." << std::endl;
return 0;
}

Covers:
Vinay (above) gave an effective work-around. What's actually causing the button's OnClick event to not work following the OnClientClick event function is that MS has defined it where, once the button is disabled (in the function called by the OnClientClick event), the button "honors" this by not trying to complete the button's activity by calling the OnClick event's defined method.
I struggled several hours trying to figure this out. Once I removed the statement to disable the submit button (that was inside the OnClientClick function), the OnClick method was called with no further problem.
Microsoft, if you're listening, once the button is clicked it should complete it's assigned activity even if it is disabled part of the way through this activity. As long as it is not disabled when it is clicked, it should complete all assigned methods.
You must have the definition of class B
before you use the class. How else would the compiler otherwise know that there exists such a function as B::add
?
Either define class B
before class A
, or move the body of A::doSomething
to after class B
have been defined, like
class B;
class A
{
B* b;
void doSomething();
};
class B
{
A* a;
void add() {}
};
void A::doSomething()
{
b->add();
}
I'm a big fan of resque/resque scheduler. You can not only run repeating cron-like tasks but also tasks at specific times. The downside is, it requires a Redis server.
Remove all your failed downloads:

You have to select the device in the schemes menu in the top left where you used to select between simulator/device. It won’t let you archive a build for the simulator.
Or you may find that if the iOS device is already selected the archive box isn’t selected when you choose “Edit Schemes” => “Build”.
The expression df1$id %in% idNums1
produces a logical vector. To negate it, you need to negate the whole vector:

Just for the sake of completeness, I would suggest using the InnerHTML way as well - even though I would not call it the best way...
document.getElementById("image-holder").innerHTML = "<img src='image.png' alt='The Image' />";
By the way, innerHTML is not that bad
To get dpi:
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
// will either be DENSITY_LOW, DENSITY_MEDIUM or DENSITY_HIGH
int dpiClassification = dm.densityDpi;
// these will return the actual dpi horizontally and vertically
float xDpi = dm.xdpi;
float yDpi = dm.ydpi;

.The android.arch.lifecycle package provides classes and interfaces that let you build lifecycle-aware components
Your application should implement the LifecycleObserver interface:
public class MyApplication extends Application implements LifecycleObserver {
@Override
public void onCreate() {
super.onCreate();
ProcessLifecycleOwner.get().getLifecycle().addObserver(this);
}
@OnLifecycleEvent(Lifecycle.Event.ON_STOP)
private void onAppBackgrounded() {
Log.d("MyApp", "App in background");
}
@OnLifecycleEvent(Lifecycle.Event.ON_START)
private void onAppForegrounded() {
Log.d("MyApp", "App in foreground");
}
}
To do that, you need to add this dependency to your build.gradle file:
dependencies {
implementation "android.arch.lifecycle:extensions:1.1.1"
}
As recommended by Google, you should minimize the code executed in the lifecycle methods of activities:
A common pattern is to implement the actions of the dependent components in the lifecycle methods of activities and fragments. However, this pattern leads to a poor organization of the code and to the proliferation of errors. By using lifecycle-aware components, you can move the code of dependent components out of the lifecycle methods and into the components themselves.
You can read more here: https://developer.android.com/topic/libraries/architecture/lifecycle
I found another way that works or an extra step to some of the answers here especially if you want to change the domain as well. It works in Android Studio 1.4. This is what I did:
build.gradle
file and change the Application Id in defaultConfig to the same name as in manifest and rebuild the project.So for example if you want to rename "com.example.app" to "com.YourDomain.app", open a file under the package to be renamed, in the package breadcrumbs, set your cursor to "example" part of the domain and hit Shift + F6 and rename package to "YourDomain".
This is easily achieved either programmatically, in your code, or declaratively in either the web.config or the app.config.
You can programmatically create a proxy like so:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("[ultimate destination of your request]");
WebProxy myproxy = new WebProxy("[your proxy address]", [your proxy port number]);
myproxy.BypassProxyOnLocal = false;
request.Proxy = myproxy;
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
You're basically assigning the WebProxy
object to the request
object's proxy
property. This request
will then use the proxy
you define.
To achieve the same thing declaratively, you can do the following:
<system.net>
<defaultProxy>
<proxy
proxyaddress="http://[your proxy address and port number]"
bypassonlocal="false"
/>
</defaultProxy>
</system.net>
within your web.config or app.config. This sets a default proxy that all http requests will use. Depending upon exactly what you need to achieve, you may or may not require some of the additional attributes of the defaultProxy / proxy element, so please refer to the documentation for those.
baseKey choice;
if (Enum.TryParse("HKEY_LOCAL_MACHINE", out choice)) {
uint value = (uint)choice;
// `value` is what you're looking for
} else { /* error: the string was not an enum member */ }
Before .NET 4.5, you had to do the following, which is more error-prone and throws an exception when an invalid string is passed:
(uint)Enum.Parse(typeof(baseKey), "HKEY_LOCAL_MACHINE")
You might want to look at Quick-R, which has a lot of nice little tutorials on how you can do basic statistics in R. For example on correlations:
If it has to be "nested", this would be one way, to get your job done:
SELECT o.name AS country, o.headofstate
FROM country o
WHERE o.headofstate like 'A%'
AND (
SELECT i.population
FROM city i
WHERE i.id = o.capital
) > 100000
A JOIN
would be more efficient than a correlated subquery, though. Can it be, that who ever gave you that task is not up to speed himself?
You should use a shared preference to store the property and act upon it using service binding from your activities. If you use binding only, (that is never use startService), then your service would run only when you bind to it, (bind onResume and unbind onPause) that would make it run on foreground only, and if you do want to work on background you can use the regular start stop service.
How about the Omondo Plugin for Eclipse. I have used it and I find it to be quite useful. Although if you are generating diagrams for large sources, you might have to start Eclipse with more memory.
There is now a an approach to do this, using Doctrine's Criteria.
A full example can be seen in How to use a findBy method with comparative criteria, but a brief answer follows.
use \Doctrine\Common\Collections\Criteria;
// Add a not equals parameter to your criteria
$criteria = new Criteria();
$criteria->where(Criteria::expr()->neq('prize', 200));
// Find all from the repository matching your criteria
$result = $entityRepository->matching($criteria);
The path is a list of directories where the command prompt will look for executable files, if it can't find it in the current directory. The OP seems to be trying to add the actual executable, when it just needs to specify the path where the executable is.
