paxdiablo has it!, use plain ol' python. The numpy version is, perhaps not surprisingly, the slowest of the lot. Probably because it's looking for arrays, where the other versions just order their arguments.
Anyway, what I did to solve this problem(on Ubuntu).
Defined in what cases I need to run these commands. For most ubuntu users there is a home folder (hidden file .bashrc
).
In which you can record the launch of these commands. But these commands will be triggered when you enter the bash
command in the console.
Since I have a shell .zshrc then I did the following:
open console: gedit .zshrc
When the file opens, add the following line:
./.add_device_permissions.sh
After or before, we need to create this file: .add_device_permissions.sh
in which we write the following:
#!/bin/bash
# Add permissions
ADB="/home/vadimm/Android/Sdk/platform-tools/adb"
$ADB devices
$ADB kill-server
cat .permissions_redmi_note | sudo -S $ADB devices
$ADB kill-server
cat .permissions_redmi_note | sudo -S $ADB devices
Also we need create .permissions_redmi_note where we need to hardcode our password.
.zshrc
unnecessary we can specify the path when starting the system itself: Startup Applications Preferences
Where we press on "Add" and write our command: /home/vadimm/.add_device_permissions.sh
./adb devices
./adb kill-server
sudo ./adb devices
./adb kill-server
./adb devices
Today I learn some simple and good click event handling using tkinter gui library in python3, which I would like to share inside this thread.
from tkinter import *
cnt = 0
def MsgClick(event):
children = root.winfo_children()
for child in children:
# print("type of widget is : " + str(type(child)))
if str(type(child)) == "<class 'tkinter.Message'>":
# print("Here Message widget will destroy")
child.destroy()
return
def MsgMotion(event):
print("Mouse position: (%s %s)" % (event.x, event.y))
return
def ButtonClick(event):
global cnt, msg
cnt += 1
msg = Message(root, text="you just clicked the button..." + str(cnt) + "...time...")
msg.config(bg='lightgreen', font=('times', 24, 'italic'))
msg.bind("<Button-1>", MsgClick)
msg.bind("<Motion>", MsgMotion)
msg.pack()
#print(type(msg)) tkinter.Message
def ButtonDoubleClick(event):
import sys; sys.exit()
root = Tk()
root.title("My First GUI App in Python")
root.minsize(width=300, height=300)
root.maxsize(width=400, height=350)
button = Button(
root, text="Click Me!", width=40, height=3
)
button.pack()
button.bind("<Button-1>", ButtonClick)
button.bind("<Double-1>", ButtonDoubleClick)
root.mainloop()
Hope it will help someone...

Sidenote: What you got there, is actually no jQuery object, but just a plain JavaScript Object.
Take a look at Traverse. It will recursively walk an object tree for you and at every node you have a number of different objects you can access - key of current node, value of current node, parent of current node, full key path of current node, etc. https://github.com/substack/js-traverse. I've used it to good effect on objects that I wanted to scrub circular references to and when I need to do a deep clone while transforming various data bits. Here's some code pulled form their samples to give you a flavor of what it can do.
var id = 54;
var callbacks = {};
var obj = { moo : function () {}, foo : [2,3,4, function () {}] };
var scrubbed = traverse(obj).map(function (x) {
if (typeof x === 'function') {
callbacks[id] = { id : id, f : x, path : this.path };
this.update('[Function]');
id++;
}
});
console.dir(scrubbed);
console.dir(callbacks);

There’s a nice approach to this problem that uses vector cross products. Define the 2-dimensional vector cross product v × w to be vx wy - vy wx.
Suppose the two line segments run from p to p + r and from q to q + s. Then any point on the first line is representable as p + t r (for a scalar parameter t) and any point on the second line as q + u s (for a scalar parameter u).
The two lines intersect if we can find t and u such that:
p + t r = q + u s
Cross both sides with s, getting
(p + t r) × s = (q + u s) × s
And since s × s = 0, this means
t (r × s) = (q - p) × s
And therefore, solving for t:
t = (q - p) × s / (r × s)
In the same way, we can solve for u:
(p + t r) × r = (q + u s) × r
u (s × r) = (p - q) × r
u = (p - q) × r / (s × r)
To reduce the number of computation steps, it's convenient to rewrite this as follows (remembering that s × r = - r × s):
u = (q - p) × r / (r × s)
Now there are four cases:
If r × s = 0 and (q - p) × r = 0, then the two lines are collinear.
In this case, express the endpoints of the second segment (q and q + s) in terms of the equation of the first line segment (p + t r):
t0 = (q - p) · r / (r · r)
t1 = (q + s - p) · r / (r · r) = t0 + s · r / (r · r)
If the interval between t0 and t1 intersects the interval [0, 1] then the line segments are collinear and overlapping; otherwise they are collinear and disjoint.
Note that if s and r point in opposite directions, then s · r < 0 and so the interval to be checked is [t1, t0] rather than [t0, t1].
If r × s = 0 and (q - p) × r ? 0, then the two lines are parallel and non-intersecting.
If r × s ? 0 and 0 = t = 1 and 0 = u = 1, the two line segments meet at the point p + t r = q + u s.
Otherwise, the two line segments are not parallel but do not intersect.
Credit: this method is the 2-dimensional specialization of the 3D line intersection algorithm from the article "Intersection of two lines in three-space" by Ronald Goldman, published in Graphics Gems, page 304. In three dimensions, the usual case is that the lines are skew (neither parallel nor intersecting) in which case the method gives the points of closest approach of the two lines.
function isset(element) {
return element.length > 0;
}
Or, as a jQuery extension:
$.fn.exists = function() { return this.length > 0; };
// later ...
if ( $("#id").exists() ) {
// do something
}
You can't update more that one table in a single statement, however the error message you get is because of the aliases, you could try this :
BEGIN TRANSACTION
update A
set A.ORG_NAME = @ORG_NAME
from table1 A inner join table2 B
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID
update B
set B.REF_NAME = @REF_NAME
from table2 B inner join table1 A
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID
COMMIT
After looking on the accepted answer I realized that if know size of required vector then we have to use a loop to initialize every element
But I found new to do this using default_structure_element like following...
#include <bits/stdc++.h>
typedef long long ll;
using namespace std;
typedef struct subject {
string name;
int marks;
int credits;
}subject;
int main(){
subject default_subject;
default_subject.name="NONE";
default_subject.marks = 0;
default_subject.credits = 0;
vector <subject> sub(10,default_subject); // default_subject to initialize
//to check is it initialised
for(ll i=0;i<sub.size();i++) {
cout << sub[i].name << " " << sub[i].marks << " " << sub[i].credits << endl;
}
}
Then I think its good to way to initialize a vector of the struct, isn't it?
If you want to query the results from a temporary table inside the same query, you can use # temp tables, or @ table variables (I personally prefer @), for querying outside of the scope you would either want to use ## global temp tables or create a new table with the results.

Today, there are JS libraries for you, if you don't want to get into the nitty gritty of the different methods described on this page.
On of these is https://github.com/hubspot/offline. It checks for the connectivity of a pre-defined URI, by default your favicon. It automatically detects when the user's connectivity has been reestablished and provides neat events like up
and down
, which you can bind to in order to update your UI.
you can use 'capture.output' like below. This allows you to use the data later:
log <- capture.output({
test <- CensReg.SMN(cc=cc,x=x,y=y, nu=NULL, type="Normal")
})

Use robocopy
. Robocopy is shipped by default on Windows Vista and newer, and is considered the replacement for xcopy
. (xcopy
has some significant limitations, including the fact that it can't handle paths longer than 256 characters, even if the filesystem can).
robocopy c:\ d:\ /e /zb /copyall /purge /dcopy:dat
Note that using /purge
on the root directory of the volume will cause Robocopy to apply the requested operation on files inside the System Volume Information directory. Run robocopy /?
for help. Also note that you probably want to open the command prompt as an administrator to be able to copy system files. To speed things up, use /b
instead of /zb
.

Guys I had this problem for 1 month and did everything but couldn't fix it, but now I know the solution.
I use a shared linux hosting, when my admin changed the php to 5.3 I got many error for the "file_put_contents" code. try to test my plan:
In your host create a file like mytest.php, and put this code in and save:
<?php mail('Your-EMail','Email-Title','Email-Message'); ?>
Open the URL "www.your-domain.com/mytest.php" one time and then check your email. you should have an email from your host with the information you entered in mytest.php, check the sender name. if its from Nobody you have problem about "Permission Denied" because something not defined and if the sender name is like my id: [email protected] you dont have prob.
My admin changed the server and installed the host again I think and the problem got solved, tell your host administration what I told you and maybe they find the answer.
hope it helps you!
Here you go:
public static byte[] ConvertToByteArray(string str, Encoding encoding)
{
return encoding.GetBytes(str);
}
public static String ToBinary(Byte[] data)
{
return string.Join(" ", data.Select(byt => Convert.ToString(byt, 2).PadLeft(8, '0')));
}
// Use any sort of encoding you like.
var binaryString = ToBinary(ConvertToByteArray("Welcome, World!", Encoding.ASCII));
Very simple:
df['C'] = df['A'] + df['B']
Change the checkboxes so that the name includes the index inside the brackets:
<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>">
The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.
It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.
Are you doing heavy DOM manipulation? I would use jQuery and Backbone.
Very data driven app? Angular with its nice data binding.
Game programming? None - direct to canvas; maybe a game engine.

I have just started using Linux a week ago, so I really hope to help you on this. I am using nano text editor to edit the files. run apt-get install nano if you don't have it. Google on it to know more.
I know this is a bit old, but here is a much easier way...
Run your query with default settings (puts results in grid format, if your's is not in grid format, see below)
Right click on grid results and click "Save Results As" and save it.
If your results are not in grid format, right click where you write the query, hover "Results To" and click "Results To Grid"
Be aware you do NOT capture the column headers!
Good Luck!
Edit httpd.conf file, which is in /etc/httpd/conf/httpd.conf

After the line no. 555 (in my case) . Check for the file permissions and restart the server.
service httpd restart
Now, it will work . Still you are facing the same problem, disable the seLinux
in /etc/selinux/config
change SELINUX=disabled
and restart the server as mentioned above and try it.
Hope this helps
This is because PHP uses the period character .
for string concatenation, not the plus character +
. Therefore to append to a string you want to use the .=
operator:
for ($i=1;$i<=100;$i++)
{
$selectBox .= '<option value="' . $i . '">' . $i . '</option>';
}
$selectBox .= '</select>';
Automatic garbage collection is the process of looking at heap memory, identifying which objects are in use and which are not, and deleting the unused objects. An in use object, or a referenced object, means that some part of your program still maintains a pointer to that object. An unused object, or unreferenced object, is no longer referenced by any part of your program. So the memory used by an unreferenced object can be reclaimed.
In a programming language like C, allocating and deallocating memory is a manual process. In Java, process of deallocating memory is handled automatically by the garbage collector. Please check the link for a better understanding. http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/gc01/index.html
Positive integer:
if (parseInt(values, 10) > 0) {
}
There are three ways of doing this.
let say you have a list of integers
my_list = [100,200,300]
"-".join(str(n) for n in my_list)
"-".join([str(n) for n in my_list])
"-".join(map(str, my_list))
However as stated in the example of timeit on python website at https://docs.python.org/2/library/timeit.html using a map is faster. So I would recommend you using "-".join(map(str, my_list))
you can just use
ls > filenames.txt
(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd
to go to that folder first, or you can ls ~/docs > filenames.txt
The short answer:
If you don't know what reinterpret_cast
stands for, don't use it. If you will need it in the future, you will know.
Full answer:
Let's consider basic number types.
When you convert for example int(12)
to unsigned float (12.0f)
your processor needs to invoke some calculations as both numbers has different bit representation. This is what static_cast
stands for.
On the other hand, when you call reinterpret_cast
the CPU does not invoke any calculations. It just treats a set of bits in the memory like if it had another type. So when you convert int*
to float*
with this keyword, the new value (after pointer dereferecing) has nothing to do with the old value in mathematical meaning.
Example: It is true that reinterpret_cast
is not portable because of one reason - byte order (endianness). But this is often surprisingly the best reason to use it. Let's imagine the example: you have to read binary 32bit number from file, and you know it is big endian. Your code has to be generic and works properly on big endian (e.g. some ARM) and little endian (e.g. x86) systems. So you have to check the byte order. It is well-known on compile time so you can write You can write a function to achieve this:constexpr
function:
/*constexpr*/ bool is_little_endian() {
std::uint16_t x=0x0001;
auto p = reinterpret_cast<std::uint8_t*>(&x);
return *p != 0;
}
Explanation: the binary representation of x
in memory could be 0000'0000'0000'0001
(big) or 0000'0001'0000'0000
(little endian). After reinterpret-casting the byte under p
pointer could be respectively 0000'0000
or 0000'0001
. If you use static-casting, it will always be 0000'0001
, no matter what endianness is being used.
EDIT:
In the first version I made example function is_little_endian
to be constexpr
. It compiles fine on the newest gcc (8.3.0) but the standard says it is illegal. The clang compiler refuses to compile it (which is correct).
Not very hard, just use m.get(i)
to get the value from the list.

I just figure it out lately on how easy it is to make your bootstrap v3.1.1 being non-responsive. This includes navbars to not to collpase. I don't know if everyone knows this but I'd like to share it.
Two Steps to a Non-responsive Bootsrap v3.1.1
First, create a css file name it as non-responsive.css. Make sure to append it to your themes or link right after the bootstrap css files.
Second, paste this code to your non-responsive.css:
/* Template-specific stuff
*
* Customizations just for the template; these are not necessary for anything
* with disabling the responsiveness.
*/
/* Account for fixed navbar */
body {
min-width: 970px;
padding-top: 70px;
padding-bottom: 30px;
}
/* Finesse the page header spacing */
.page-header {
margin-bottom: 30px;
}
.page-header .lead {
margin-bottom: 10px;
}
/* Non-responsive overrides
*
* Utilitze the following CSS to disable the responsive-ness of the container,
* grid system, and navbar.
*/
/* Reset the container */
.container {
width: 970px;
max-width: none !important;
}
/* Demonstrate the grids */
.col-xs-4 {
padding-top: 15px;
padding-bottom: 15px;
background-color: #eee;
background-color: rgba(86,61,124,.15);
border: 1px solid #ddd;
border: 1px solid rgba(86,61,124,.2);
}
.container .navbar-header,
.container .navbar-collapse {
margin-right: 0;
margin-left: 0;
}
/* Always float the navbar header */
.navbar-header {
float: left;
}
/* Undo the collapsing navbar */
.navbar-collapse {
display: block !important;
height: auto !important;
padding-bottom: 0;
overflow: visible !important;
}
.navbar-toggle {
display: none;
}
.navbar-collapse {
border-top: 0;
}
.navbar-brand {
margin-left: -15px;
}
/* Always apply the floated nav */
.navbar-nav {
float: left;
margin: 0;
}
.navbar-nav > li {
float: left;
}
.navbar-nav > li > a {
padding: 15px;
}
/* Redeclare since we override the float above */
.navbar-nav.navbar-right {
float: right;
}
/* Undo custom dropdowns */
.navbar .navbar-nav .open .dropdown-menu {
position: absolute;
float: left;
background-color: #fff;
border: 1px solid #ccc;
border: 1px solid rgba(0, 0, 0, .15);
border-width: 0 1px 1px;
border-radius: 0 0 4px 4px;
-webkit-box-shadow: 0 6px 12px rgba(0, 0, 0, .175);
box-shadow: 0 6px 12px rgba(0, 0, 0, .175);
}
.navbar-default .navbar-nav .open .dropdown-menu > li > a {
color: #333;
}
.navbar .navbar-nav .open .dropdown-menu > li > a:hover,
.navbar .navbar-nav .open .dropdown-menu > li > a:focus,
.navbar .navbar-nav .open .dropdown-menu > .active > a,
.navbar .navbar-nav .open .dropdown-menu > .active > a:hover,
.navbar .navbar-nav .open .dropdown-menu > .active > a:focus {
color: #fff !important;
background-color: #428bca !important;
}
.navbar .navbar-nav .open .dropdown-menu > .disabled > a,
.navbar .navbar-nav .open .dropdown-menu > .disabled > a:hover,
.navbar .navbar-nav .open .dropdown-menu > .disabled > a:focus {
color: #999 !important;
background-color: transparent !important;
}
That's all and Enjoy..^^

You can also post multiple inputs with the same name and have them save into an array by adding empty square brackets to the input name like this:
<input type="text" name="comment[]" value="comment1"/>
<input type="text" name="comment[]" value="comment2"/>
<input type="text" name="comment[]" value="comment3"/>
<input type="text" name="comment[]" value="comment4"/>
If you use php:
print_r($_POST['comment'])
you will get this:
Array ( [0] => 'comment1' [1] => 'comment2' [2] => 'comment3' [3] => 'comment4' )
If your compiler supports (at least part of) C++11 you could do something like:
for (auto& t : myMap)
std::cout << t.first << " "
<< t.second.first << " "
<< t.second.second << "\n";
For C++03 I'd use std::copy
with an insertion operator instead:
typedef std::pair<string, std::pair<string, string> > T;
std::ostream &operator<<(std::ostream &os, T const &t) {
return os << t.first << " " << t.second.first << " " << t.second.second;
}
// ...
std:copy(myMap.begin(), myMap.end(), std::ostream_iterator<T>(std::cout, "\n"));
Put this inside the onCreate() method of MainActivity1.java
Button btnEins = (Button) findViewById(R.id.save);
btnEins.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intencion = new Intent(v.getContext(),MainActivity2.class );
startActivity(intencion);
}
});
A good example of where this matters in practice is the ConcurrentSkipListSet
implementation in the JDK, which states:
Beware that, unlike in most collections, the size method is not a constant-time operation.
This is a clear case where isEmpty()
is much more efficient than checking whether size()==0
.
You can see why, intuitively, this might be the case in some collections. If it's the sort of structure where you have to traverse the whole thing to count the elements, then if all you want to know is whether it's empty, you can stop as soon as you've found the first one.
DPI should not be stored in an bitmap image file, as most sources of data for bitmaps render it meaningless.
A bitmap image is stored as pixels. Pixels have no inherent size in any respect. It's only at render time - be it monitor, printer, or automated crossstitching machine - that DPI matters.
A 800x1000 pixel bitmap image, printed at 100 dpi, turns into a nice 8x10" photo. Printed at 200 dpi, the EXACT SAME bitmap image turns into a 4x5" photo.
Capture an image with a digital camera, and what does DPI mean? It's certainly not the size of the area focused onto the CCD imager - that depends on the distance, and with NASA returning images of galaxies that are 100,000 light years across, and 2 million light years apart, in the same field of view, what kind of DPI do you get from THAT information?
Don't fall victim to the idea of the DPI of a bitmap image - it's a mistake. A bitmap image has no physical dimensions (save for a few micrometers of storage space in RAM or hard drive). It's only a displayed image, or a printed image, that has a physical size in inches, or millimeters, or furlongs.
In code to load resource in the executing assembly where my image 'Freq.png' was in the folder "Icons" and defined as "Resource".
this.Icon = new BitmapImage(new Uri(@"pack://application:,,,/"
+ Assembly.GetExecutingAssembly().GetName().Name
+ ";component/"
+ "Icons/Freq.png", UriKind.Absolute));
I also made a function if anybody would like it...
/// <summary>
/// Load a resource WPF-BitmapImage (png, bmp, ...) from embedded resource defined as 'Resource' not as 'Embedded resource'.
/// </summary>
/// <param name="pathInApplication">Path without starting slash</param>
/// <param name="assembly">Usually 'Assembly.GetExecutingAssembly()'. If not mentionned, I will use the calling assembly</param>
/// <returns></returns>
public static BitmapImage LoadBitmapFromResource(string pathInApplication, Assembly assembly = null)
{
if (assembly == null)
{
assembly = Assembly.GetCallingAssembly();
}
if (pathInApplication[0] == '/')
{
pathInApplication = pathInApplication.Substring(1);
}
return new BitmapImage(new Uri(@"pack://application:,,,/" + assembly.GetName().Name + ";component/" + pathInApplication, UriKind.Absolute));
}
Usage:
this.Icon = ResourceHelper.LoadBitmapFromResource("Icons/Freq.png");
I always use this:
// Lock form
this.MaximumSize = this.Size;
this.MinimumSize = this.Size;
This way you can always resize the form from Designer without changing code.
Use the below code to find the count of number of matches that the regex finds in your input
Pattern p = Pattern.compile(regex, Pattern.MULTILINE | Pattern.DOTALL);// "regex" here indicates your predefined regex.
Matcher m = p.matcher(pattern); // "pattern" indicates your string to match the pattern against with
boolean b = m.matches();
if(b)
count++;
while (m.find())
count++;
This is a generalized code not specific one though, tailor it to suit your need
Please feel free to correct me if there is any mistake.
players
is a list which needs to be indexed by integers. You seem to be using it like a dictionary. Maybe you could use unpacking -- Something like:
name, score = player
(if the player
list is always a constant length).
There's not much more advice we can give you without knowing what query
is and how it works.
It's worth pointing out that the entire code you posted doesn't make a whole lot of sense. There's an IndentationError
on the second line. Also, your function is looping over some iterable, but unconditionally returning during the first iteration which isn't usually what you actually want to do.
onCreate(Bundle savedInstanceState) Function in Android:
When an Activity first call or launched then onCreate(Bundle savedInstanceState) method is responsible to create the activity.
When ever orientation(i.e. from horizontal to vertical or vertical to horizontal) of activity gets changed or when an Activity gets forcefully terminated by any Operating System then savedInstanceState i.e. object of Bundle Class will save the state of an Activity.
After Orientation changed then onCreate(Bundle savedInstanceState) will call and recreate the activity and load all data from savedInstanceState.
Basically Bundle class is used to stored the data of activity whenever above condition occur in app.
onCreate() is not required for apps. But the reason it is used in app is because that method is the best place to put initialization code.
You could also put your initialization code in onStart() or onResume() and when you app will load first, it will work same as in onCreate().
HashMaps do not preserve ordering:
This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.
Take a look at LinkedHashMap, which guarantees a predictable iteration order.
def bubbleSort ( arr ):
swapped = True
length = len ( arr )
j = 0
while swapped:
swapped = False
j += 1
for i in range ( length - j ):
if arr [ i ] > arr [ i + 1 ]:
# swap
tmp = arr [ i ]
arr [ i ] = arr [ i + 1]
arr [ i + 1 ] = tmp
swapped = True
if __name__ == '__main__':
# test list
a = [ 67, 45, 39, -1, -5, -44 ];
print ( a )
bubbleSort ( a )
print ( a )
First of all you should fix modal HTML structure. Now it's not correct, you don't need class .hide
:
<div id="edit-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body edit-content">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
Then links should point to this modal via data-target
attribute:
<a href="#myModal" data-toggle="modal" id="1" data-target="#edit-modal">Edit 1</a>
Finally Js part becomes very simple:
$('#edit-modal').on('show.bs.modal', function(e) {
var $modal = $(this),
esseyId = e.relatedTarget.id;
$.ajax({
cache: false,
type: 'POST',
url: 'backend.php',
data: 'EID=' + essayId,
success: function(data) {
$modal.find('.edit-content').html(data);
}
});
})
You can call up the color picker from any Cocoa application (TextEdit, Mail, Keynote, Pages, etc.) by hitting Shift-Command-C
The following article explains more about using Mac OS's Color Picker.
http://www.macworld.com/article/46746/2005/09/colorpickersecrets.html
You can convert it to a string, and then to an int:
print(int("".join(str(x) for x in [7,7,7,7])))
I've had the same problem, was missing a slash in servlet url in web.xml
replace
<servlet-mapping>
<servlet-name>jsonservice</servlet-name>
<url-pattern>jsonservice</url-pattern>
</servlet-mapping>
with
<servlet-mapping>
<servlet-name>jsonservice</servlet-name>
<url-pattern>/jsonservice</url-pattern>
</servlet-mapping>
Take a look at the instance methods here:
This has useful methods such as yesterday, tomorrow, beginning_of_week, ago, etc.
Examples:
Time.now.yesterday
Time.now.ago(2.days).end_of_day
Time.now.next_month.beginning_of_month
Should be
~/([^/]*)$~
Means: Match a /
and then everything, that is not a /
([^/]*
) until the end ($
, "end"-anchor).
I use the ~
as delimiter, because now I don't need to escape the forward-slash /
.
Using plain javascript:
element.parentNode
In jQuery:
element.parent()
You can't. You can call a JS function from HTML outputted by PHP, but that's a whole 'nother thing.
Of course there is! Win CMD can do a lot more than just split text files :)
Split a text file into separate files of 'max' lines each:
Split text file (max lines each):
: Initialize
set input=file.txt
set max=10000
set /a line=1 >nul
set /a file=1 >nul
set out=!file!_%input%
set /a max+=1 >nul
echo Number of lines in %input%:
find /c /v "" < %input%
: Split file
for /f "tokens=* delims=[" %i in ('type "%input%" ^| find /v /n ""') do (
if !line!==%max% (
set /a line=1 >nul
set /a file+=1 >nul
set out=!file!_%input%
echo Writing file: !out!
)
REM Write next file
set a=%i
set a=!a:*]=]!
echo:!a:~1!>>out!
set /a line+=1 >nul
)
If above code hangs or crashes, this example code splits files faster (by writing data to intermediate files instead of keeping everything in memory):
eg. To split a file with 7,600 lines into smaller files of maximum 3000 lines.

Tested on Win 10 x64 CMD, on 4.4GB text file, 5651982 lines.
No, you cannot. But you can create a user defined table function.
Another good method is: First create a new package with the desired name by right clicking on the java folder -> new -> package.
Then, select and drag all your classes to the new package. Android Studio will refactor the package name everywhere.
Finally, delete the old package.
or Look into this post
Please use Google API console
Create a new project
For the created project goto API access
There you will find your Client ID and Secret.
And the API key in the last is your developer key.
I think Jon Skeet has the correct answer. I'd just like to add that you can access shadowed variables from superclasses of superclasses by casting this
:
interface I { int x = 0; }
class T1 implements I { int x = 1; }
class T2 extends T1 { int x = 2; }
class T3 extends T2 {
int x = 3;
void test() {
System.out.println("x=\t\t" + x);
System.out.println("super.x=\t\t" + super.x);
System.out.println("((T2)this).x=\t" + ((T2)this).x);
System.out.println("((T1)this).x=\t" + ((T1)this).x);
System.out.println("((I)this).x=\t" + ((I)this).x);
}
}
class Test {
public static void main(String[] args) {
new T3().test();
}
}
which produces the output:
x= 3 super.x= 2 ((T2)this).x= 2 ((T1)this).x= 1 ((I)this).x= 0
(example from the JLS)
However, this doesn't work for method calls because method calls are determined based on the runtime type of the object.
Here is a bit of code from one of my applications... Let me know if it suits your needs. You can use this if you know the file you want to use.
URL defaultImage = ClassA.class.getResource("/packageA/subPackage/image-name.png");
File imageFile = new File(defaultImage.toURI());
Hope that helps.
I've ran into this topic, because i was struggling with dashed lines too (gnuplot 4.6 patchlevel 0)
If you use:
set termoption dashed
Your posted code will work accordingly.
Related question:
However, if I want to export a png with:
set terminal png, this isn't working anymore. Anyone got a clue why?
Turns out, out, gnuplots png export library doesnt support this.
Possbile solutions:
pngcairo
as your terminal (set terminal pngcairo
) it will workAlso relevant to the discussion is the relatively unknown Erl
function. If you have numeric labels within your code procedure, e.g.,
Sub AAA()
On Error Goto ErrorHandler
1000:
' code
1100:
' more code
1200:
' even more code that causes an error
1300:
' yet more code
9999: ' end of main part of procedure
ErrorHandler:
If Err.Number <> 0 Then
Debug.Print "Error: " + CStr(Err.Number), Err.Descrption, _
"Last Successful Line: " + CStr(Erl)
End If
End Sub
The Erl
function returns the most recently encountered numberic line label. In the example above, if a run-time error occurs after label 1200:
but before 1300:
, the Erl
function will return 1200
, since that is most recenlty sucessfully encountered line label. I find it to be a good practice to put a line label immediately above your error handling block. I typcially use 9999
to indicate that the main part of the procuedure ran to its expected conculsion.
NOTES:
Line labels MUST be positive integers -- a label like MadeItHere:
isn't recogonized by Erl
.
Line labels are completely unrelated to the actual line numbers of a VBIDE CodeModule
. You can use any positive numbers you want, in any order you want. In the example above, there are only 25 or so lines of code, but the line label numbers begin at 1000
. There is no relationship between editor line numbers and line label numbers used with Erl
.
Line label numbers need not be in any particular order, although if they are not in ascending, top-down order, the efficacy and benefit of Erl
is greatly diminished, but Erl
will still report the correct number.
Line labels are specific to the procedure in which they appear. If procedure ProcA
calls procedure ProcB
and an error occurs in ProcB
that passes control back to ProcA
, Erl
(in ProcA
) will return the most recently encounterd line label number in ProcA
before it calls ProcB
. From within ProcA
, you cannot get the line label numbers that might appear in ProcB
.
Use care when putting line number labels within a loop. For example,
For X = 1 To 100
500:
' some code that causes an error
600:
Next X
If the code following line label 500
but before 600
causes an error, and that error arises on the 20th iteration of the loop, Erl
will return 500
, even though 600
has been encounterd successfully in the previous 19 interations of the loop.
Proper placement of line labels within the procedure is critical to using the Erl
function to get truly meaningful information.
There are any number of free utilies on the net that will insert numeric line label in a procedure automatically, so you have fine-grained error information while developing and debugging, and then remove those labels once code goes live.
If your code displays error information to the end user if an unexpected error occurs, providing the value from Erl
in that information can make finding and fixing the problem VASTLY simpler than if value of Erl
is not reported.
The accepted answer using button.tag
as information carrier which button has actually been pressed is solid and widely accepted but rather limited since a tag can only hold Int
s.
You can make use of Swift's awesome closure-capabilities to have greater flexibility and cleaner code.
I recommend this article: How to properly do buttons in table view cells using Swift closures by Jure Zove.
Applied to your problem:
Declare a variable that can hold a closure in your tableview cell like
var buttonTappedAction : ((UITableViewCell) -> Void)?
Add an action when the button is pressed that only executes the closure. You did it programmatically with cell.yes.targetForAction("connected", withSender: self)
but I would prefer an @IBAction
outlet :-)
@IBAction func buttonTap(sender: AnyObject) {
tapAction?(self)
}
func connected(sender: UIButton!) { ... }
as a closure to cell.tapAction = {<closure content here...>}
. Please refer to the article for a more precise explanation and please don't forget to break reference cycles when capturing variables from the environment.So I was having a similar issue and I managed to solve it by putting the script tag with my JS file after the closing body tag.
I assume it's because it makes sure there's something to reference, but I am not entirely sure.
This is an old question, but here's a class I just built based on the article from Jim Mischel at InformIt linked by Doug L.
class Array2DSort : IComparer<int>
{
// maintain a reference to the 2-dimensional array being sorted
string[,] _sortArray;
int[] _tagArray;
int _sortIndex;
protected string[,] SortArray { get { return _sortArray; } }
// constructor initializes the sortArray reference
public Array2DSort(string[,] theArray, int sortIndex)
{
_sortArray = theArray;
_tagArray = new int[_sortArray.GetLength(0)];
for (int i = 0; i < _sortArray.GetLength(0); ++i) _tagArray[i] = i;
_sortIndex = sortIndex;
}
public string[,] ToSortedArray()
{
Array.Sort(_tagArray, this);
string[,] result = new string[
_sortArray.GetLength(0), _sortArray.GetLength(1)];
for (int i = 0; i < _sortArray.GetLength(0); i++)
{
for (int j = 0; j < _sortArray.GetLength(1); j++)
{
result[i, j] = _sortArray[_tagArray[i], j];
}
}
return result;
}
// x and y are integer row numbers into the sortArray
public virtual int Compare(int x, int y)
{
if (_sortIndex < 0) return 0;
return CompareStrings(x, y, _sortIndex);
}
protected int CompareStrings(int x, int y, int col)
{
return _sortArray[x, col].CompareTo(_sortArray[y, col]);
}
}
Given an unsorted 2D array data
of arbitrary size that you want to sort on column 5 you just do this:
Array2DSort comparer = new Array2DSort(data, 5);
string[,] sortedData = comparer.ToSortedArray();
Note the virtual Compare
method and protected SortArray
so you can create specialized subclasses that always sort on a particular column or do specialized sorting on multiple columns or whatever you want to do. That's also why CompareStrings
is broken out and protected - any subclasses can use it for simple comparisons instead of typing out the full SortArray[x, col].CompareTo(SortArray[y, col])
syntax.
A functional language (ideally) allows you to write a mathematical function, i.e. a function that takes n arguments and returns a value. If the program is executed, this function is logically evaluated as needed.1
A procedural language, on the other hand, performs a series of sequential steps. (There's a way of transforming sequential logic into functional logic called continuation passing style.)
As a consequence, a purely functional program always yields the same value for an input, and the order of evaluation is not well-defined; which means that uncertain values like user input or random values are hard to model in purely functional languages.
1 As everything else in this answer, that’s a generalisation. This property, evaluating a computation when its result is needed rather than sequentially where it’s called, is known as “laziness”. Not all functional languages are actually universally lazy, nor is laziness restricted to functional programming. Rather, the description given here provides a “mental framework” to think about different programming styles that are not distinct and opposite categories but rather fluid ideas.
you are having the FindOpenSSL.cmake file in the cmake module(path usr/shared.cmake-3.5/modules) # Search OpenSSL
find_package(OpenSSL REQUIRED)
if( OpenSSL_FOUND )
include_directories(${OPENSSL_INCLUDE_DIRS})
link_directories(${OPENSSL_LIBRARIES})

This ought to do the trick: just limit the result to 1 row; if a row comes back the $lectureName
is Assigned, otherwise it's Available.
function checkLectureStatus($lectureName)
{
$con = connectvar();
mysql_select_db("mydatabase", $con);
$result = mysql_query(
"SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");
if(mysql_fetch_array($result) !== false)
return 'Assigned';
return 'Available';
}
You'll want to use JavaScript's Array splice
method:
var tag_story = [1,3,56,6,8,90],
id_tag = 90,
position = tag_story.indexOf(id_tag);
if ( ~position ) tag_story.splice(position, 1);
P.S. For an explanation of that cool ~
tilde shortcut, see this post:
Using a ~
tilde with indexOf
to check for the existence of an item in an array.
Note: IE < 9 does not support .indexOf()
on arrays. If you want to make sure your code works in IE, you should use jQuery's $.inArray()
:
var tag_story = [1,3,56,6,8,90],
id_tag = 90,
position = $.inArray(id_tag, tag_story);
if ( ~position ) tag_story.splice(position, 1);
If you want to support IE < 9 but don't already have jQuery on the page, there's no need to use it just for $.inArray
. You can use this polyfill instead.
The "iterable interface" in python consists of two methods __next__()
and __iter__()
. The __next__
function is the most important, as it defines the iterator behavior - that is, the function determines what value should be returned next. The __iter__()
method is used to reset the starting point of the iteration. Often, you will find that __iter__()
can just return self when __init__()
is used to set the starting point.
See the following code for defining a Class Reverse which implements the "iterable interface" and defines an iterator over any instance from any sequence class. The __next__()
method starts at the end of the sequence and returns values in reverse order of the sequence. Note that instances from a class implementing the "sequence interface" must define a __len__()
and a __getitem__()
method.
class Reverse:
"""Iterator for looping over a sequence backwards."""
def __init__(self, seq):
self.data = seq
self.index = len(seq)
def __iter__(self):
return self
def __next__(self):
if self.index == 0:

Before you can add files in an unversioned directory, you have to add the directory itself to the versioning:
svn add directory_name
will add the directory directory_name
and all sub-directories: http://svnbook.red-bean.com/en/1.8/svn.ref.svn.c.add.html
You can refer below link to understand in detail (best explanation which I could find):
https://www.programmergirl.com/java-8-map-flatmap-difference/
Both map and flatMap - accept Function. The return type of map() is a single value whereas flatMap is returning stream of values
<R> Stream<R> map(Function<? super T, ? extends R> mapper)
<R> Stream<R> flatMap(Function<? super T, ? extends Stream<? extends R>> mapper)
I would suggest using wire shark to trace packets. If you are using Ubuntu, sudo-apt get wireshark. Like Joni stated the only way to figure out whats going wrong is to follow the GET requests and their associated responses.
I'll take a stab at it:
/^[a-z](?:_?[a-z0-9]+)*$/i
Explained:
/
^ # match beginning of string
[a-z] # match a letter for the first char
(?: # start non-capture group
_? # match 0 or 1 '_'
[a-z0-9]+ # match a letter or number, 1 or more times
)* # end non-capture group, match whole group 0 or more times
$ # match end of string
/i # case insensitive flag
The non-capture group takes care of a) not allowing two _
's (it forces at least one letter or number per group) and b) only allowing the last char to be a letter or number.
Some test strings:
"a": match
"_": fail
"zz": match
"a0": match
"A_": fail
"a0_b": match
"a__b": fail
"a_1_c": match
&
is used to separate commands. Therefore you can use ^
to escape the &
.

I found this topic while searching for run script for startup and shutdown Windows 10. Those answers above didn't working. For me on windows 10 worked when I put scripts to task scheduler. How to do this: press window key and write Task scheduler, open it, then on the right is Add task... button. Here you can add scripts. PS: I found action for startup and logout user, there is not for shutdown.
If I understand, what you want to do is disregard the orientation of the UIImage? If so then you could do this:
UIImage *originalImage = [... whatever ...];
UIImage *imageToDisplay =
[UIImage imageWithCGImage:[originalImage CGImage]
scale:[originalImage scale]
orientation: UIImageOrientationUp];
So you're creating a new UIImage with the same pixel data as the original (referenced via its CGImage property) but you're specifying an orientation that doesn't rotate the data.
You could just add one needed external jar file to the project. Go to your project-->java build path-->libraries, add external JARS.Then add your downloaded file from the formal website. My default name is commons-codec-1.10.jar
The above method works good.
Another method (I am assuming web here) is to create your page. Add controls to the page. Then while in design mode go to: Tools > Generate Local Resource. A resource file will automatically appear in the solution with all the controls in the page mapped in the resource file.
To create resources for other languages, append the 4 character language to the end of the file name, before the extension (Account.aspx.en-US.resx, Account.aspx.es-ES.resx...etc).
To retrieve specific entries in the code-behind, simply call this method: GetLocalResourceObject([resource entry key/name])
.
Environment variables must be strings, so use
os.environ["DEBUSSY"] = "1"
to set the variable DEBUSSY
to the string 1
.
To access this variable later, simply use:
print(os.environ["DEBUSSY"])
Child processes automatically inherit the environment variables of the parent process -- no special action on your part is required.
People are talking about characters when one can compress an IP address into raw data.
So in principle, since we only use IPv4 (32bit) or IPv6 (128bit), that means you need at most 128 bits of space, or 128/8 = 16 bytes!
Which is much less than the suggested 39 bytes (assuming charset is ascii).
That said, you will have to decode and encode the IP address into/from the raw data, which in itself is a trivial thing to do (I've done it before, see PHP's ip2long()
for 32-bit IPs).
Edit: inet_pton
(and its opposite, inet_ntop()
) does what you need, and works with both address types. But beware, on Windows it's available since PHP 5.3.
Use replace
method of strings not strip
:
s = s.replace(',','')
An example:
>>> s = 'Foo, bar'
>>> s.replace(',',' ')
'Foo bar'
>>> s.replace(',','')
'Foo bar'
>>> s.strip(',') # clears the ','s at the start and end of the string which there are none
'Foo, bar'
>>> s.strip(',') == s
True
maybe your mysql-server didn't started
you can try
/usr/local/bin/mysql.server start
I just published react-delta which solves this exact sort of scenario. In my opinion, useEffect
has too many responsibilities.
Object.is
react-delta
breaks useEffect
's responsibilities into several smaller hooks.
Responsibility #1
usePrevious(value)
useLatest(value)
useDelta(value, options)
useDeltaArray(valueArray, options)
useDeltaObject(valueObject, options)
some(deltaArray)
every(deltaArray)
Responsibility #2
In my experience, this approach is more flexible, clean, and concise than useEffect
/useRef
solutions.
int first = string.indexOf("is");
int second = string.indexOf("is", first + 1);
This overload starts looking for the substring from the given index.
I was going through 2 way SSL in springboot. I have made all correct configuration service tomcat server and service caller RestTemplate. but I was getting error as "java.security.cert.CertificateException: No subject alternative names present"
After going through solutions, I found, JVM needs this certificate otherwise it gives handshaking error.
Now, how to add this to JVM.
go to jre/lib/security/cacerts file. we need to add our server certificate file to this cacerts file of jvm.
Command to add server cert to cacerts file via command line in windows.
C:\Program Files\Java\jdk1.8.0_191\jre\lib\security>keytool -import -noprompt -trustcacerts -alias sslserver -file E:\spring_cloud_sachin\ssl_keys\sslserver.cer -keystore cacerts -storepass changeit
Check server cert is installed or not:
C:\Program Files\Java\jdk1.8.0_191\jre\lib\security>keytool -list -keystore cacerts
you can see list of certificates installed:

Try this:
<img v-bind:src="'/media/avatars/' + joke.avatar" />
Don't forget single quote around your path string. also in your data check you have correctly defined image variable.

Disable the page validation if you really need the special characters like, >
, , <
, etc. Then ensure that when the user input is displayed, the data is HTML-encoded.
There is a security vulnerability with the page validation, so it can be bypassed. Also the page validation shouldn't be solely relied on.
In Kotlin you can use extension
fun Context.getMyDrawable(id : Int) : Drawable?{
return ContextCompat.getDrawable(this, id)
}
then use like
context.getMyDrawable(R.drawable.my_icon)
String[] result = "hi i'm paul".split("\\s+");
to split across one or more cases.
Or you could take a look at Apache Common StringUtils. It has StringUtils.split(String str)
method that splits string using white space as delimiter. It also has other useful utility methods
If you are a regular Eclipse user than you might have got this error many times. The error simply says, “you’ve made changes in files in your workspace from outside eclipse”. The simplest solution would be to select the project and press F5 (Right click -> Refresh).
if you need more explanation you can read from this web site
npm start
will run whatever you have defined for the start
command of the scripts
object in your package.json
file.
So if it looks like this:
"scripts": {
"start": "ng serve"
}
Then npm start
will run ng serve
.
Try this:
Function UserNameWindows() As String
UserName = Environ("USERNAME")
End Function
This isn't mentioned in any of the other answers. If you want a value that orms (should) hydrate as boolean you can use
CONVERT(bit, 0) -- false CONVERT(bit, 1) -- true
This gives you a bit which is not a boolean. You cannot use that value in an if statement for example:
IF CONVERT(bit, 0)
BEGIN
print 'Yay'
END
woudl not parse. You would still need to write
IF CONVERT(bit, 0) = 0
So its not terribly useful.

From the definition of height:
Applies to: all elements but non-replaced inline elements, table columns, and column groups
An a
element is, by default an inline element (and it is non-replaced).
You need to change the display (directly with the display property or indirectly, e.g. with float).
A combination of both float: left;
white-space: nowrap;
worked for me.
Each of them independently didn't accomplish the desired result.
It's not firing because the value hasn't "changed". It's the same value. Unfortunately, you can't achieve the desired behaviour using the change
event.
You can handle the blur
event and do whatever processing you need when the user leaves the select box. That way you can run the code you need even if the user selects the same value.
I had a similar problem with this error message in the logs:
Target WSGI script '/home/web2py/wsgihandler.py' cannot be loaded as Python module.
The solution was the deletion of an incorrect WSGIPythonHome directive (pointing to the application directory) from /etc/httpd/conf.d/wsgi.conf
I'm on RedHat using CentOS repositories.
Recommend following Graham Dumpleton's installation/configuration instructions. Testing configuration against the helloworld application showed me that mod_wsgi
was working and the configuration was at fault.
However, the error message gave little clue as to what was wrong.
You can use templated interfaces like this:
interface Map<T> {
[K: string]: T;
}
let dict: Map<number> = {};
dict["one"] = 1;
<?php if($condition) : ?>
<a href="http://yahoo.com">This will only display if $condition is true</a>
<?php endif; ?>
By request, here's elseif and else (which you can also find in the docs)
<?php if($condition) : ?>
<a href="http://yahoo.com">This will only display if $condition is true</a>
<?php elseif($anotherCondition) : ?>
more html
<?php else : ?>
even more html
<?php endif; ?>
It's that simple.
The HTML will only be displayed if the condition is satisfied.
You're declaring a virtual
function and not defining it:
virtual void calculateCredits();
Either define it or declare it as:
virtual void calculateCredits() = 0;
Or simply:

Accessing CSS property & manipulating is quite easy using .css(). For example, to change single property:
$("selector").css('top', '50px');
char c = 10; // 1 byte
int *p = (int*)&c; // 4 bytes
Since this results in a 4-byte pointer pointing to 1 byte of allocated memory, writing to this pointer will either cause a run-time error or will overwrite some adjacent memory.
*p = 5; // run-time error: stack corruption
In contrast to the C-style cast, the static cast will allow the compiler to check that the pointer and pointee data types are compatible, which allows the programmer to catch this incorrect pointer assignment during compilation.
int *q = static_cast<int*>(&c); // compile-time error
To force the pointer conversion, in the same way as the C-style cast does in the background, the reinterpret cast would be used instead.
int *r = reinterpret_cast<int*>(&c); // forced conversion
This cast handles conversions between certain unrelated types, such as from one pointer type to another incompatible pointer type. It will simply perform a binary copy of the data without altering the underlying bit pattern. Note that the result of such a low-level operation is system-specific and therefore not portable. It should be used with caution if it cannot be avoided altogether.
This one is only used to convert object pointers and object references into other pointer or reference types in the inheritance hierarchy. It is the only cast that makes sure that the object pointed to can be converted, by performing a run-time check that the pointer refers to a complete object of the destination type. For this run-time check to be possible the object must be polymorphic. That is, the class must define or inherit at least one virtual function. This is because the compiler will only generate the needed run-time type information for such objects.
Dynamic cast examples
In the example below, a MyChild pointer is converted into a MyBase pointer using a dynamic cast. This derived-to-base conversion succeeds, because the Child object includes a complete Base object.
class MyBase
{
public:
virtual void test() {}
};
class MyChild : public MyBase {};
int main()
{
MyChild *child = new MyChild();
MyBase *base = dynamic_cast<MyBase*>(child); // ok
}
The next example attempts to convert a MyBase pointer to a MyChild pointer. Since the Base object does not contain a complete Child object this pointer conversion will fail. To indicate this, the dynamic cast returns a null pointer. This gives a convenient way to check whether or not a conversion has succeeded during run-time.
MyBase *base = new MyBase();
MyChild *child = dynamic_cast<MyChild*>(base);
if (child == 0)
std::cout << "Null pointer returned";
If a reference is converted instead of a pointer, the dynamic cast will then fail by throwing a bad_cast exception. This needs to be handled using a try-catch statement.
#include <exception>
// …
try
{
MyChild &child = dynamic_cast<MyChild&>(*base);
}
catch(std::bad_cast &e)
{
std::cout << e.what(); // bad dynamic_cast
}
The advantage of using a dynamic cast is that it allows the programmer to check whether or not a conversion has succeeded during run-time. The disadvantage is that there is a performance overhead associated with doing this check. For this reason using a static cast would have been preferable in the first example, because a derived-to-base conversion will never fail.
MyBase *base = static_cast<MyBase*>(child); // ok
However, in the second example the conversion may either succeed or fail. It will fail if the MyBase object contains a MyBase instance and it will succeed if it contains a MyChild instance. In some situations this may not be known until run-time. When this is the case dynamic cast is a better choice than static cast.
// Succeeds for a MyChild object
MyChild *child = dynamic_cast<MyChild*>(base);
If the base-to-derived conversion had been performed using a static cast instead of a dynamic cast the conversion would not have failed. It would have returned a pointer that referred to an incomplete object. Dereferencing such a pointer can lead to run-time errors.
// Allowed, but invalid
MyChild *child = static_cast<MyChild*>(base);
// Incomplete MyChild object dereferenced
(*child);
This one is primarily used to add or remove the const modifier of a variable.
const int myConst = 5;
int *nonConst = const_cast<int*>(&myConst); // removes const
Although const cast allows the value of a constant to be changed, doing so is still invalid code that may cause a run-time error. This could occur for example if the constant was located in a section of read-only memory.
*nonConst = 10; // potential run-time error
Const cast is instead used mainly when there is a function that takes a non-constant pointer argument, even though it does not modify the pointee.
void print(int *p)
{
std::cout << *p;
}
The function can then be passed a constant variable by using a const cast.
print(&myConst); // error: cannot convert
// const int* to int*
print(nonConst); // allowed
You probably want to assign the lastname
you are reading out here
lastname = sheet.cell(row=r, column=3).value
to something; currently the program just forgets it
you could do that two lines after, like so
unpaidMembers[name] = lastname, email
your program will still crash at the same place, because .items()
still won't give you 3-tuples but rather something that has this structure: (name, (lastname, email))
good news is, python can handle this
for name, (lastname, email) in unpaidMembers.items():
etc.
The message means that both the packages have functions with the same names. In this particular case, the testthat
and assertive
packages contain five functions with the same name.
R will look through the search
path to find functions, and will use the first one that it finds.
search()
## [1] ".GlobalEnv" "package:assertive" "package:testthat"
## [4] "tools:rstudio" "package:stats" "package:graphics"
## [7] "package:grDevices" "package:utils" "package:datasets"
## [10] "package:methods" "Autoloads" "package:base"
In this case, since assertive
was loaded after testthat
, it appears earlier in the search path, so the functions in that package will be used.
is_true
## function (x, .xname = get_name_in_parent(x))
## {
## x <- coerce_to(x, "logical", .xname)
## call_and_name(function(x) {
## ok <- x & !is.na(x)
## set_cause(ok, ifelse(is.na(x), "missing", "false"))
## }, x)
## }
<bytecode: 0x0000000004fc9f10>
<environment: namespace:assertive.base>
The functions in testthat
are not accessible in the usual way; that is, they have been masked.
You can explicitly provide a package name when you call a function, using the double colon operator, ::
. For example:
testthat::is_true
## function ()
## {
## function(x) expect_true(x)
## }
## <environment: namespace:testthat>
If you know about the function name clash, and don't want to see it again, you can suppress the message by passing warn.conflicts = FALSE
to library
.
library(testthat)
library(assertive, warn.conflicts = FALSE)
# No output this time
Alternatively, suppress the message with suppressPackageStartupMessages
:
library(testthat)
suppressPackageStartupMessages(library(assertive))
# Also no output
If you have altered some of R's startup configuration options (see ?Startup
) you may experience different function masking behavior than you might expect. The precise order that things happen as laid out in ?Startup
should solve most mysteries.
For example, the documentation there says:
Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.
Which implies that when 3rd party packages are loaded via files like .Rprofile
you may see functions from those packages masked by those in default packages like stats, rather than the reverse, if you loaded the 3rd party package after R's startup procedure is complete.
First, get a character vector of all the environments on the search path. For convenience, we'll name each element of this vector with its own value.
library(dplyr)
envs <- search() %>% setNames(., .)
For each environment, get the exported functions (and other variables).
fns <- lapply(envs, ls)
Turn this into a data frame, for easy use with dplyr.
fns_by_env <- data_frame(
env = rep.int(names(fns), lengths(fns)),
fn = unlist(fns)
)
Find cases where the object appears more than once.
fns_by_env %>%
group_by(fn) %>%
tally() %>%
filter(n > 1) %>%
inner_join(fns_by_env)
To test this, try loading some packages with known conflicts (e.g., Hmisc
, AnnotationDbi
).
The conflicted
package throws an error with a helpful error message, whenever you try to use a variable with an ambiguous name.
library(conflicted)
library(Hmisc)
units
## Error: units found in 2 packages. You must indicate which one you want with ::
## * Hmisc::units
## * base::units
Here's a solution that uses more modern syntax and is less verbose than the ones already provided:
const canvas = document.querySelector("canvas");
const ctx = canvas.getContext("2d");
const video = document.querySelector("video");
video.addEventListener('play', () => {
function step() {
ctx.drawImage(video, 0, 0, canvas.width, canvas.height)
requestAnimationFrame(step)
}
requestAnimationFrame(step);
})
Some useful links:
This unfortunately breaks other things. Here is the fix I found on another site that seemed to work for me:
I'd say leave the X-UA-Compatible
as "IE=8"
and add the following code to the bottom of your master page:
<script language="javascript">
/* IE11 Fix for SP2010 */
if (typeof(UserAgentInfo) != 'undefined' && !window.addEventListener)
{
UserAgentInfo.strBrowser=1;
}
</script>
This fixes a bug in core.js
which incorrectly calculates that sets UserAgentInfo.strBrowse=3
for IE11 and thus supporting addEventListener
. I'm not entirely sure on the details other than that but the combination of keeping IE=8 and using this script is working for me. Fingers crossed until I find the next IE11/SharePoint "bug"!
I deleted my server and added it back. IT happened because I shut down the eclipse manually via task manager and it did not shut down the tomcat.

Simple example for how to set JAVA_HOME with setx.exe
in command line:
setx JAVA_HOME "C:\Program Files (x86)\Java\jdk1.7.0_04"
This will set environment variable "JAVA_HOME" for current user. If you want to set a variable for all users, you have to use option "-m". Here is an example:
setx -m JAVA_HOME "C:\Program Files (x86)\Java\jdk1.7.0_04"
Note: you have to execute this command as Administrator.
Note: Make sure to run the command setx from an command-line Admin window
With Git 2.23 (August 2019) and the new (still experimental) command git restore
, seen in "How to reset all files from working directory but not from staging area?", that would be:
git fetch

The idea is: git restore
only deals with files, not files and branches as git checkout
does.
See "Confused by git checkout

A fast and compact approach could be:
def picklines(thefile, whatlines):
return [x for i, x in enumerate(thefile) if i in whatlines]
this accepts any open file-like object thefile
(leaving up to the caller whether it should be opened from a disk file, or via e.g a socket, or other file-like stream) and a set of zero-based line indices whatlines
, and returns a list, with low memory footprint and reasonable speed. If the number of lines to be returned is huge, you might prefer a generator:
def yieldlines(thefile, whatlines):
return (x for i, x in enumerate(thefile) if i in whatlines)
which is basically only good for looping upon -- note that the only difference comes from using rounded rather than square parentheses in the return
statement, making a list comprehension and a generator expression respectively.
Further note that despite the mention of "lines" and "file" these functions are much, much more general -- they'll work on any iterable, be it an open file or any other, returning a list (or generator) of items based on their progressive item-numbers. So, I'd suggest using more appropriately general names;-).

In other words, replace rootNode parameter with this.getDOMNode() in the latest version of React.

WooCommerce is using this function to show billing and shipping addresses in the customer profile. So this will might help.
The user needs to be logged in to get address using this function.
wc_get_account_formatted_address( 'billing' );
or
wc_get_account_formatted_address( 'shipping' );

As Neel Bhaat has explained in this blog, there are many different tools that can be used for this purpose. Some are AWS provided, where most are third party tools. All these tools require you to save your AWS account key and secret in the tool itself. Be very cautious when using third party tools, as the credentials you save in might cost you, your entire worth and drop you dead.
Therefore, I always recommend using the AWS CLI for this purpose. You can simply install this from this link. Next, run the following command and save your key, secret values in AWS CLI.
aws configure
And use the following command to sync your AWS S3 Bucket to your local machine. (The local machine should have AWS CLI installed)
aws s3 sync <source> <destination>
Examples:
1) For AWS S3 to Local Storage
aws s3 sync <S3Uri> <LocalPath>
2) From Local Storage to AWS S3
aws s3 sync <LocalPath> <S3Uri>
3) From AWS s3 bucket to another bucket
aws s3 sync <S3Uri> <S3Uri>
In some cases you can pipe after the command a Out-Null
command | Out-Null
Even if this can somehow be done it is a terrible idea since it would be possible to get a sequence that then gets used by another record!
A much better idea is to save the record and then retrieve the sequence afterwards.
This is a real, real life scenario, because it actually happened yesterday:
Alternatives to not using !important
in my answer included:
!important
.So, a benefit of !important
is that it sometimes saves time. If you use it very sparingly like this, it can be a useful tool.
If you're using it just because you don't understand how specificity works, you're doing it wrong.
Another use for !important
is when you're writing some kind of external widget type thing, and you want to be sure that your styles will be the ones applied, see:
CTRL+Space
This can also happen if you've been working on your scripts and functions and have been moving them around (i.e. changed the location of the definition) which could have accidentally created a looping reference.
You may find that the situation is solved if you just reset the iPython kernal to clear any old assignments:
%reset
or menu->restart terminal
I'll throw my hat in here:

If only one checkbox should be checked in the same time use RadioButtonFor instead:
@Html.RadioButtonFor(model => model.Type,1, new { @checked = "checked" }) fultime
@Html.RadioButtonFor(model => model.Type,2) party
@Html.RadioButtonFor(model => model.Type,3) next option...
If one more one could be checked in the same time use excellent extension: CheckBoxListFor:
Hope,it will help
<foo name="port">
<value>${my.server.port:8088}</value>
</foo>
should work for you to have 8088 as default port

you would have to write down some method to create a temporary array and then copy it like
public String[] increaseArray(String[] theArray, int increaseBy)
{
int i = theArray.length;
int n = ++i;
String[] newArray = new String[n];
for(int cnt=0;cnt<theArray.length;cnt++)
{
newArray[cnt] = theArray[cnt];
}
return newArray;
}
or The ArrayList would be helpful to resolve your problem.
If you have the SUPER privilege, you can set the global server time zone value at runtime with this statement:
mysql> SET GLOBAL time_zone = timezone;
If you are using Python on Ubuntu and you only want it to work on Ubuntu a substantially faster way is the use the terminal's locate
program like this.
import subprocess
def find_files(file_name):
command = ['locate', file_name]
output = subprocess.Popen(command, stdout=subprocess.PIPE).communicate()[0]
output = output.decode()
search_results = output.split('\n')
return search_results
search_results
is a list
of the absolute file paths. This is 10,000's of times faster than the methods above and for one search I've done it was ~72,000 times faster.
Generic function that is validated at compilation!
public static bool IsBetween<T>(this T item, T start, T end) where T : IComparable
{
return item.CompareTo(start) >= 0 && item.CompareTo(end) <= 0;
}

You can try this it'll convert the date format to DD-MM-YYYY:

hi you can try doing this
link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, {class: 'dock-item'}
or even
link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, class: 'dock-item'
note that the position of the curly braces is very important, because if you miss them out, rails will assume they form a single hash parameters (read more about this here)
and according to the api for link_to:
link_to(name, options = {}, html_options = nil)
hope it helps! =)
Since people don't tend to read comments, here is an answer that mostly duplicates what I wrote here:
the root cause of the issue is the fact that android system does not call getItem
to obtain fragments that are actually displayed, but instantiateItem
. This method first tries to lookup and reuse a fragment instance for a given tab in FragmentManager
. Only if this lookup fails (which happens only the first time when FragmentManager
is newly created) then getItem
is called. It is for obvious reasons not to recreate fragments (that may be heavy) for example each time a user rotates his device.
To solve this, instead of creating fragments with Fragment.instantiate
in your activity, you should do it with pagerAdapter.instantiateItem
and all these calls should be surrounded by startUpdate/finishUpdate
method calls that start/commit fragment transaction respectively. getItem
should be the place where fragments are really created using their respective constructors.
List<Fragment> fragments = new Vector<Fragment>();
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.myLayout);
ViewPager viewPager = (ViewPager) findViewById(R.id.myViewPager);
MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(adapter);
((TabLayout) findViewById(R.id.tabs)).setupWithViewPager(viewPager);
adapter.startUpdate(viewPager);
fragments.add(adapter.instantiateItem(viewPager, 0));
fragments.add(adapter.instantiateItem(viewPager, 1));
// and so on if you have more tabs...
adapter.finishUpdate(viewPager);
}
class MyPagerAdapter extends FragmentPagerAdapter {
public MyPagerAdapter(FragmentManager manager) {super(manager);}
@Override public int getCount() {return 2;}
@Override public Fragment getItem(int position) {
if (position == 0) return new Fragment0();
if (position == 1) return new Fragment1();
return null; // or throw some exception
}
@Override public CharSequence getPageTitle(int position) {
if (position == 0) return getString(R.string.tab0);
if (position == 1) return getString(R.string.tab1);
return null; // or throw some exception
}
}
Another alternative
Just check the class in the Abstract class and Assert or Exception, whatever you fancy.
@implementation Orange
- (instancetype)init
{
self = [super init];
NSAssert([self class] != [Orange class], @"This is an abstract class");
if (self) {
}
return self;
}
@end
This removes the necessity to override init
In my case I was missing new
inside the type definition.
some-js-component.d.ts
file:
import * as React from "react";
export default class SomeJSXComponent extends React.Component<any, any> {
new (props: any, context?: any)

file where I was trying to import the untyped component:
import SomeJSXComponent from 'some-js-component'
const NewComp = ({ asdf }: NewProps) => <SomeJSXComponent withProps={asdf} />
You didn't specify a GradientType
:

Try this : (http://jsfiddle.net/TpqVx/)
.left-div {
float: left;
width: 100px;
/*height: 20px;*/
margin-right: 8px;
background-color: linen;
}
.right-div {
margin-left: 108px;
background-color: lime;
}??
<div class="left-div">
</div>
<div class="right-div">
My requirements are <b>[A]</b> Content in the two divs should line up at the top, <b>[B]</b> Long text in right-div should not wrap underneath left-div, and <b>[C]</b> I do not want to specify a width of right-div. I don't want to set the width of right-div because this markup needs to work within different widths.
</div>
<div style='clear:both;'> </div>
Hints :
float:left
in your left-most div only.height
, but anyway...<div 'clear:both'> </div>
after your last div.I have a feeling that your ClientID
is not of a string type (zero-terminated char*
or std::string
) but some integral type (e.g. int
) so you need to convert number to the string first:
std::stringstream ss;
ss << ClientID;
query.append(ss.str());
But you can use operator+
as well (instead of append
):
query += ss.str();
The up-to-date right way to do this asynchronously using ES 2016 standards of async and await (as of Node 7) would be the following:
const crypto = require('crypto');
function generateToken({ stringBase = 'base64', byteLength = 48 } = {}) {
return new Promise((resolve, reject) => {
crypto.randomBytes(byteLength, (err, buffer) => {
if (err) {
reject(err);
} else {
resolve(buffer.toString(stringBase));
}
});
});
}
async function handler(req, res) {
// default token length
const newToken = await generateToken();
console.log('newToken', newToken);
// pass in parameters - adjust byte length
const shortToken = await generateToken({byteLength: 20});
console.log('newToken', shortToken);
}
This works out of the box in Node 7 without any Babel transformations
You could also try this :
function replaceStr(str, find, replace) {
for (var i = 0; i < find.length; i++) {
str = str.replace(new RegExp(find[i], 'gi'), replace[i]);
}
return str;
}
var text = "#here_is_the_one#";
var find = ["#","_"];
var replace = ['',' '];
text = replaceStr(text, find, replace);
console.log(text);
find
refers to the text to be found and replace
to the text to be replaced with
This will be replacing case insensitive characters. To do otherway just change the Regex flags as required. Eg: for case sensitive replace :
new RegExp(find[i], 'g')
We can use map
function
print map(str, EmployeeList)
Would it be possible to change your URL structure?
For what I was working on I tried a route for
url: "Download/{fileName}"
but it failed with anything that had a . in it.
I switched the route to
routes.MapRoute(
name: "Download",
url: "{fileName}/Download",
defaults: new { controller = "Home", action = "Download", }
);
Now I can put in localhost:xxxxx/File1.doc/Download
and it works fine.
My helpers in the view also picked up on it
@Html.ActionLink("click here", "Download", new { fileName = "File1.doc"})
that makes a link to the localhost:xxxxx/File1.doc/Download
format as well.
Maybe you could put an unneeded word like "/view" or action on the end of your route so your property can end with a trailing /
something like /mike.smith/view
Just run this: select * from v$version
Here is a more complete answer with regard to InnoDB. It is a bit of a lengthy process, but can be worth the effort.
Keep in mind that /var/lib/mysql/ibdata1
is the busiest file in the InnoDB infrastructure. It normally houses six types of information:
Pictorial Representation of ibdata1
Many people create multiple ibdata
files hoping for better disk-space management and performance, however that belief is mistaken.
OPTIMIZE TABLE
?Unfortunately, running OPTIMIZE TABLE
against an InnoDB table stored in the shared table-space file ibdata1
does two things:
ibdata1
ibdata1
grow because the contiguous data and index pages are appended to ibdata1
You can however, segregate Table Data and Table Indexes from ibdata1
and manage them independently.
OPTIMIZE TABLE
with innodb_file_per_table
?Suppose you were to add innodb_file_per_table
to /etc/my.cnf (my.ini)
. Can you then just run OPTIMIZE TABLE
on all the InnoDB Tables?
Good News : When you run OPTIMIZE TABLE
with innodb_file_per_table
enabled, this will produce a .ibd
file for that table. For example, if you have table mydb.mytable
witha datadir of /var/lib/mysql
, it will produce the following:
/var/lib/mysql/mydb/mytable.frm
/var/lib/mysql/mydb/mytable.ibd
The .ibd
will contain the Data Pages and Index Pages for that table. Great.
Bad News : All you have done is extract the Data Pages and Index Pages of mydb.mytable
from living in ibdata
. The data dictionary entry for every table, including mydb.mytable
, still remains in the data dictionary (See the Pictorial Representation of ibdata1). YOU CANNOT JUST SIMPLY DELETE ibdata1
AT THIS POINT !!! Please note that ibdata1
has not shrunk at all.
To shrink ibdata1
once and for all you must do the following:
Dump (e.g., with mysqldump
) all databases into a .sql
text file (SQLData.sql
is used below)
Drop all databases (except for mysql
and information_schema
) CAVEAT : As a precaution, please run this script to make absolutely sure you have all user grants in place:
mkdir /var/lib/mysql_grants
cp /var/lib/mysql/mysql/* /var/lib/mysql_grants/.
chown -R mysql:mysql /var/lib/mysql_grants
Login to mysql and run SET GLOBAL innodb_fast_shutdown = 0;
(This will completely flush all remaining transactional changes from ib_logfile0
and ib_logfile1
)
Shutdown MySQL
Add the following lines to /etc/my.cnf
(or my.ini
on Windows)
[mysqld]
innodb_file_per_table
innodb_flush_method=O_DIRECT
innodb_log_file_size=1G
innodb_buffer_pool_size=4G
(Sidenote: Whatever your set for innodb_buffer_pool_size
, make sure innodb_log_file_size
is 25% of innodb_buffer_pool_size
.
Also: innodb_flush_method=O_DIRECT
is not available on Windows)
Delete ibdata*
and ib_logfile*
, Optionally, you can remove all folders in /var/lib/mysql
, except /var/lib/mysql/mysql
.
Start MySQL (This will recreate ibdata1
[10MB by default] and ib_logfile0
and ib_logfile1
at 1G each).
Import SQLData.sql
Now, ibdata1
will still grow but only contain table metadata because each InnoDB table will exist outside of ibdata1
. ibdata1
will no longer contain InnoDB data and indexes for other tables.
For example, suppose you have an InnoDB table named mydb.mytable
. If you look in /var/lib/mysql/mydb
, you will see two files representing the table:
mytable.frm
(Storage Engine Header)mytable.ibd
(Table Data and Indexes)With the innodb_file_per_table
option in /etc/my.cnf
, you can run OPTIMIZE TABLE mydb.mytable
and the file /var/lib/mysql/mydb/mytable.ibd
will actually shrink.
I have done this many times in my career as a MySQL DBA. In fact, the first time I did this, I shrank a 50GB ibdata1
file down to only 500MB!
Give it a try. If you have further questions on this, just ask. Trust me; this will work in the short term as well as over the long haul.
At Step 6, if mysql cannot restart because of the mysql
schema begin dropped, look back at Step 2. You made the physical copy of the mysql
schema. You can restore it as follows:
mkdir /var/lib/mysql/mysql
cp /var/lib/mysql_grants/* /var/lib/mysql/mysql
chown -R mysql:mysql /var/lib/mysql/mysql
Go back to Step 6 and continue
With regard to setting innodb_log_file_size to 25% of innodb_buffer_pool_size in Step 5, that's blanket rule is rather old school.
Back on July 03, 2006
, Percona had a nice article why to choose a proper innodb_log_file_size. Later, on Nov 21, 2008
, Percona followed up with another article on how to calculate the proper size based on peak workload keeping one hour's worth of changes.
I have since written posts in the DBA StackExchange about calculating the log size and where I referenced those two Percona articles.
Aug 27, 2012
: Proper tuning for 30GB InnoDB table on server with 48GB RAMJan 17, 2013
: MySQL 5.5 - Innodb - innodb_log_file_size higher than 4GB combined?Personally, I would still go with the 25% rule for an initial setup. Then, as the workload can more accurate be determined over time in production, you could resize the logs during a maintenance cycle in just minutes.
I am using MariaDB and have the similar problem.
From MariaDB site, it is recommended to fix it by
Run with a lower error reporting level:
$err_level = error_reporting(0);
$conn = mysql_connect('params');
error_reporting($err_level);
My problem fixed by using the mysqlnd driver in Ubuntu:
sudo apt-get install php5-mysqlnd
Cheers!
[update: extra information] Installing this driver also resolve PDO problem that returns integer value as a string. To keep the type as integer, after installing mysqlInd, do this
$db = new PDO('mysql:host='.$host.';dbname='.$db_name, $user, $pass,
array( PDO::ATTR_PERSISTENT => true));
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$db->setAttribute(PDO::ATTR_STRINGIFY_FETCHES, false);
try
{
$conn = new PDO("sqlsrv:Server=$server_name;Database=$db_name;ConnectionPooling=0", "", "");
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e)
{
$e->getMessage();
}
To expand this question into the realm of use outside of Excel s own VBA, the ActiveWindow property must be addressed as a child of the Excel.Application object.
Example for creating an Excel workbook from Access:
Using the Excel.Application object in another Office application's VBA project will require you to add Microsoft Excel 15.0 Object library (or equivalent for your own version).
Option Explicit
Sub xls_Build__Report()
Dim xlApp As Excel.Application, ws As Worksheet, wb As Workbook
Dim fn As String
Set xlApp = CreateObject("Excel.Application")
xlApp.DisplayAlerts = False
xlApp.Visible = True
Set wb = xlApp.Workbooks.Add
With wb
.Sheets(1).Name = "Report"
With .Sheets("Report")
'report generation here
End With
'This is where the Freeze Pane is dealt with
'Freezes top row
With xlApp.ActiveWindow
.SplitColumn = 0
.SplitRow = 1
.FreezePanes = True
End With
fn = CurrentProject.Path & "\Reports\Report_" & Format(Date, "yyyymmdd") & ".xlsx"
If CBool(Len(Dir(fn, vbNormal))) Then Kill fn
.SaveAs FileName:=fn, FileFormat:=xlOpenXMLWorkbook
End With
Close_and_Quit:
wb.Close False
xlApp.Quit
End Sub
The core process is really just a reiteration of previously submitted answers but I thought it was important to demonstrate how to deal with ActiveWindow when you are not within Excel's own VBA. While the code here is VBA, it should be directly transcribable to other languages and platforms.
To insert a sleep command you can use Thread.sleep(2000). So the code would be:
List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
Iterator<Integer> myListIterator = someList.iterator();
while (myListIterator.hasNext()) {
Integer coord = myListIterator.next();
System.out.println(coord);
Thread.Sleep(2000);
}
This would output: 10 20 30 40 50
If you want the numbers after each other you could use: System.out.print(coord +" " ); and if you want to repeat the section you can put it in another while loop.
List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
while(true)
Iterator<Integer> myListIterator = someList.iterator();
while (myListIterator.hasNext()) {
Integer coord = myListIterator.next();
System.out.print(coord + " ");
Thread.Sleep(2000);
}
}
This would output: 10 20 30 40 50 10 20 30 40 50 ... and never stop until you kill the program.
Edit: You do have to put the sleep command in a try catch block
This seems quick for me :
comm -1 -3 <(sort file1.txt) <(sort file2.txt) > output.txt
The correct CSS for setting font-size is "font-size: 35px". I.e.:
<td style="padding-left: 5px; padding-bottom:3px; font size: 35px;">
Note that this sets the font size in pixels. You can also set it in *em*s or percentage. Learn more about fonts in CSS here: http://www.w3schools.com/css/css_font.asp
here is the workaround sample.
function redirect_post($url, array $data)
{
?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript">
function closethisasap() {
document.forms["redirectpost"].submit();
}
</script>
</head>
<body onload="closethisasap();">
<form name="redirectpost" method="post" action="<? echo $url; ?>">
<?php
if ( !is_null($data) ) {
foreach ($data as $k => $v) {
echo '<input type="hidden" name="' . $k . '" value="' . $v . '"> ';
}
}
?>
</form>
</body>
</html>
<?php
exit;
}
Remove obj
and just do this inside your for loop:
arr.push(i);
Also, the i < yearEnd
condition will not include the final year, so change it to i <= yearEnd
.
Another tip: I initialized static fields in a wrong order - surprisingly it didn't bring up a Problem (NullPointerException?), instead Eclipse complained with exactly the message OP posted. Correcting the static initialization order made the class run-able. Example:
private static ScriptEngineManager factory = null;
private static ScriptEngine engine = null;
static {
engine = factory.getEngineByName("JavaScript");
// factory is supposed to initialize FIRST
factory = new ScriptEngineManager();
}
Use juffrou-reflect's BeanWrapper. It is very performant.
Here is how you can transform a bean into a map:
public static Map<String, Object> getBeanMap(Object bean) {
Map<String, Object> beanMap = new HashMap<String, Object>();
BeanWrapper beanWrapper = new BeanWrapper(BeanWrapperContext.create(bean.getClass()));
for(String propertyName : beanWrapper.getPropertyNames())
beanMap.put(propertyName, beanWrapper.getValue(propertyName));
return beanMap;
}
I developed Juffrou myself. It's open source, so you are free to use it and modify. And if you have any questions regarding it, I'll be more than happy to respond.
Cheers
Carlos
I think in this case they are the same, but here is an example where order matters:
const int* cantChangeTheData;
int* const cantChangeTheAddress;

If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web
tab. Under the Servers
section you can configure the URL. There is also a button to create the virtual directory.
Very similar to Holger's answer. If you need to grab the URL can do something like:
Uri uri = Context.Request.Url;
var scheme = uri.Scheme // returns http, https
var scheme2 = uri.Scheme + Uri.SchemeDelimiter; // returns http://, https://
var host = uri.Host; // return www.mywebsite.com
var port = uri.Port; // returns port number
The Uri class provides a whole range of methods, many which I have not listed.
In my instance, I needed to grab LocalHost
along with the Port Number
, so this is what I did:
var Uri uri = Context.Request.Url;
var host = uri.Scheme + Uri.SchemeDelimiter + uri.Host + ":" + uri.Port;
Which successfully grabbed: http://localhost:12345
I've used Blat ( http://www.blat.net/ ) for many years. It's a simple command line utility that can send email from command line. It's free and opensource.
You can use command like "Blat myfile.txt -to [email protected] -server smtp.domain.com -port 6000"
Here is some other software you can try to send email from command line (I've never used them):
http://caspian.dotconf.net/menu/Software/SendEmail/
http://www.petri.co.il/sendmail.htm
http://www.petri.co.il/software/mailsend105.zip
http://retired.beyondlogic.org/solutions/cmdlinemail/cmdlinemail.htm
Here ( http://www.petri.co.il/send_mail_from_script.htm ) you can find other various way of sending email from a VBS script, plus link to some of the mentioned software
The following VBScript code is taken from that page
Set objEmail = CreateObject("CDO.Message")
objEmail.From = "[email protected]"
objEmail.To = "[email protected]"
objEmail.Subject = "Server is down!"
objEmail.Textbody = "Server100 is no longer accessible over the network."
objEmail.Send
Save the file as something.vbs
Set Msg = CreateObject("CDO.Message")
With Msg
.To = "[email protected]"
.From = "[email protected]"
.Subject = "Hello"
.TextBody = "Just wanted to say hi."
.Send
End With
Save the file as something2.vbs
I think these VBS scripts use the windows default mail server, if present. I've not tested these scripts...
According the w3c spec height refers to the height of the viewable area e.g. on a 1280x1024 pixel resolution monitor 100% height = 1024 pixels.
min-height refers to the total height of the page including content so on a page where the content is bigger than 1024px min-height:100% will stretch to include all of the content.
The other problem then is that padding and border are added to the height and width in most modern browsers except ie6(ie6 is actually quite logical but does not conform to the spec). This is called the box model. So if you specify
min-height: 100%;
padding: 5px;
It will actually give you 100% + 5px + 5px for the height. To get around this you need a wrapper container.
<style>
.FullHeight {
height: auto !important; /* ie 6 will ignore this */
height: 100%; /* ie 6 will use this instead of min-height */
min-height: 100%; /* ie 6 will ignore this */
}
.Padded {
padding: 5px;
}
</style>
<div class="FullHeight">
<div class="Padded">
Hello i am padded.
</div
</div>
if (!resultSet.isAfterLast() ) {
System.out.println("No data");
}
isAfterLast()
also returns false for empty result set but since cursor is before first row anyways, this method seems more clear.
Vincent Robert is right in his comment How do you properly use namespaces in C++?.
Namespaces are used at the very least to help avoid name collision. In Java, this is enforced through the "org.domain" idiom (because it is supposed one won't use anything else than his/her own domain name).
In C++, you could give a namespace to all the code in your module. For example, for a module MyModule.dll, you could give its code the namespace MyModule. I've see elsewhere someone using MyCompany::MyProject::MyModule. I guess this is overkill, but all in all, it seems correct to me.
Using should be used with great care because it effectively import one (or all) symbols from a namespace into your current namespace.
This is evil to do it in a header file because your header will pollute every source including it (it reminds me of macros...), and even in a source file, bad style outside a function scope because it will import at global scope the symbols from the namespace.
The most secure way to use "using" is to import select symbols:
void doSomething()
{
using std::string ; // string is now "imported", at least,
// until the end of the function
string a("Hello World!") ;
std::cout << a << std::endl ;
}
void doSomethingElse()
{
using namespace std ; // everything from std is now "imported", at least,
// until the end of the function
string a("Hello World!") ;
cout << a << endl ;
}
You'll see a lot of "using namespace std ;" in tutorial or example codes. The reason is to reduce the number of symbols to make the reading easier, not because it is a good idea.
"using namespace std ;" is discouraged by Scott Meyers (I don't remember exactly which book, but I can find it if necessary).
Namespaces are more than packages. Another example can be found in Bjarne Stroustrup's "The C++ Programming Language".
In the "Special Edition", at 8.2.8 Namespace Composition, he describes how you can merge two namespaces AAA and BBB into another one called CCC. Thus CCC becomes an alias for both AAA and BBB:
namespace AAA
{
void doSomething() ;
}
namespace BBB
{
void doSomethingElse() ;
}
namespace CCC
{
using namespace AAA ;
using namespace BBB ;
}
void doSomethingAgain()
{
CCC::doSomething() ;
CCC::doSomethingElse() ;
}
You could even import select symbols from different namespaces, to build your own custom namespace interface. I have yet to find a practical use of this, but in theory, it is cool.
CSS is not used to define values to DOM element attributes, javascript would be more suitable for this.
Simply use something like the following - the string should be there already:
<?php
if(isset($_SERVER['SERVER_SOFTWARE'])){
echo $_SERVER['SERVER_SOFTWARE'];
}
?>
How about:
self.tableView.reloadRowsAtIndexPaths([NSIndexPath(rowNumber)], withRowAnimation: UITableViewRowAnimation.Top)

MVC vs MVVM vs MVP. What a controversial topic that many developers can spend hours and hours debating and arguing about.
For several years +AngularJS was closer to MVC (or rather one of its client-side variants), but over time and thanks to many refactorings and api improvements, it's now closer to MVVM – the $scope object could be considered the ViewModel that is being decorated by a function that we call a Controller.
Being able to categorize a framework and put it into one of the MV* buckets has some advantages. It can help developers get more comfortable with its apis by making it easier to create a mental model that represents the application that is being built with the framework. It can also help to establish terminology that is used by developers.
Having said, I'd rather see developers build kick-ass apps that are well-designed and follow separation of concerns, than see them waste time arguing about MV* nonsense. And for this reason, I hereby declare AngularJS to be MVW framework - Model-View-Whatever. Where Whatever stands for "whatever works for you".
Angular gives you a lot of flexibility to nicely separate presentation logic from business logic and presentation state. Please use it fuel your productivity and application maintainability rather than heated discussions about things that at the end of the day don't matter that much.

Personally, one of the things I love about python is the tuple-dict combination. What you have here is effectively a 2d array (where x = fruit name and y = color), and I am generally a supporter of the dict of tuples for implementing 2d arrays, at least when something like numpy
or a database isn't more appropriate. So in short, I think you've got a good approach.
Note that you can't use dicts as keys in a dict without doing some extra work, so that's not a very good solution.
That said, you should also consider namedtuple(). That way you could do this:
>>> from collections import namedtuple
>>> Fruit = namedtuple("Fruit", ["name", "color"])
>>> f = Fruit(name="banana", color="red")
>>> print f
Fruit(name='banana', color='red')
>>> f.name
'banana'
>>> f.color
'red'
Now you can use your fruitcount dict:
>>> fruitcount = {Fruit("banana", "red"):5}
>>> fruitcount[f]
5
Other tricks:
>>> fruits = fruitcount.keys()
>>> fruits.sort()
>>> print fruits
[Fruit(name='apple', color='green'),
Fruit(name='apple', color='red'),
Fruit(name='banana', color='blue'),
Fruit(name='strawberry', color='blue')]
>>> fruits.sort(key=lambda x:x.color)
>>> print fruits
[Fruit(name='banana', color='blue'),
Fruit(name='strawberry', color='blue'),
Fruit(name='apple', color='green'),
Fruit(name='apple', color='red')]
Echoing chmullig, to get a list of all colors of one fruit, you would have to filter the keys, i.e.
bananas = [fruit for fruit in fruits if fruit.name=='banana']
It is not legal to declare an instance member in a static class. Static class's cannot be instantiated hence it makes no sense to have an instance members (they'd never be accessible).
Environment variables are accessed through os.environ
import os
print(os.environ['HOME'])
Or you can see a list of all the environment variables using:
os.environ
As sometimes you might need to see a complete list!
# using get will return `None` if a key is not present rather than raise a `KeyError`
print(os.environ.get('KEY_THAT_MIGHT_EXIST'))
# os.getenv is equivalent, and can also give a default value instead of `None`
print(os.getenv('KEY_THAT_MIGHT_EXIST', default_value))
Python default installation on Windows is C:\Python
. If you want to find out while running python you can do:
import sys
print(sys.prefix)
If youre like me and had problems with the current Oracle release of 1.6 then you might want to update your JDK or set
-XX:MaxPermSize. More information is available here: http://java.dzone.com/articles/latest-java-update-fixes
os.system('cls')
works fine when I open them. It opens in cmd style.
Since we're on a subject, one can use regular expressions too
"aaabcd".replaceFirst(".$",""); //=> aaabc
if it is 64bit them - C:\Program Files (x86)\Reference Assemblies\Microsoft\WindowsPowerShell**3.0**

Lets say that you have a Text
widget called my_text_widget
.
To get input from the my_text_widget
you can use the get
function.
Let's assume that you have imported tkinter
.
Lets define my_text_widget
first, lets make it just a simple text widget.
my_text_widget = Text(self)
To get input from a text
widget you need to use the get
function, both, text
and entry
widgets have this.
input = my_text_widget.get()
The reason we save it to a variable is to use it in the further process, for example, testing for what's the input.
You might also have made it work by specifying the full path to node. Furthermore, when you want to run a shell command as a daemon you should close stdin by adding 1<&- before the &.
Another method that people should consider using is Shared Workers. I know it's a cutting edge concept, but you can create a relay on a Shared Worker that is MUCH faster than localstorage, and doesn't require a relationship between the parent/child window, as long as you're on the same origin.
See my answer here for some discussion I made about this.
For adding compression to the resulting zip file, check out this link.
You need to change:

to
zip = zipfile.ZipFile('Python.zip', 'w', zipfile.ZIP_DEFLATED)
None of the options except SELECT doesn't allow database name as used in SELECT, so I wrote this:
SELECT COUNT(*) AS cnt FROM information_schema.TABLES
WHERE CONCAT(table_schema,".",table_name)="db_name.table_name";
According to the documentation:
$validator = Validator::make($request->all(), [
'file' => 'max:500000',
]);
The value is in kilobytes. I.e. max:10240
= max 10 MB.
Please try out this one.
d =[{'value': 'apple', 'blah': 2}, {'value': 'banana', 'blah': 3} , {'value':
'cars', 'blah': 4}]
b=d[0]['value']
c=d[1]['value']
d=d[2]['value']
new_list=[b,c,d]
print(new_list)
Output:
['apple', 'banana', 'cars']
The problem for me was a new server that System.Web.Routing was of version 3.5 while web.config requested version 4.0.0.0. The resolution was
%WINDIR%\Framework\v4.0.30319\aspnet_regiis -i
%WINDIR%\Framework64\v4.0.30319\aspnet_regiis -i
You may want to try View.getRootView()

If the data is a static or global variable, it is zero-filled by default, so just declare it myStruct _m;
If the data is a local variable or a heap-allocated zone, clear it with memset
like:
memset(&m, 0, sizeof(myStruct));
Current compilers (e.g. recent versions of gcc
) optimize that quite well in practice. This works only if all zero values (include null pointers and floating point zero) are represented as all zero bits, which is true on all platforms I know about (but the C standard permits implementations where this is false; I know no such implementation).
You could perhaps code myStruct m = {};
or myStruct m = {0};
(even if the first member of myStruct
is not a scalar).
My feeling is that using memset
for local structures is the best, and it conveys better the fact that at runtime, something has to be done (while usually, global and static data can be understood as initialized at compile time, without any cost at runtime).
To do it in non interactive mode (from a script):
systemctl start mysqld
MYSQL_ROOT_TMP_PSW=$(grep 'temporary password' $logpath/mysqld.log |sed "s|.*: ||")
## POPULATE SCHEMAS WITH ROOT USER
/usr/bin/mysql --connect-expired-password -u root -p${MYSQL_ROOT_TMP_PSW} < "$mysql_init_script"
Here's the head of the init script
SET GLOBAL validate_password_policy=LOW;
FLUSH privileges;
SET PASSWORD = PASSWORD('MYSQL_ROOT_PSW');
FLUSH privileges;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
FLUSH privileges;
...
Then restart the service systemctl restart mysqld
