just a bit tough but (hairbo gave me the idea)
CSS:
.pagecontainer {
display: none;
}
JS:
function load() {
document.getElementById('noscriptmsg').style.display = "none";
document.getElementById('load').style.display = "block";
/* rest of js*/
}
HTML:
<body onload="load();">
<div class="pagecontainer" id="load">
Page loading....
</div>
<div id="noscriptmsg">
You don't have javascript enabled. Good luck with that.
</div>
</body>
would work in any case right? even if the noscript tag is unsupported (only some css required) any one knows a non css solution?
I have implemented the Samsung File Selector Dialog, it provides the ability to open, save file, file extension filter, and create new directory in the same dialog I think it worth trying Here is the Link you have to log in to Samsung developer site to view the solution
You could type "prop" and then press tab twice. That will generate the following.
public TYPE Type { get; set; }
Then you change "TYPE" and "Type":
public string myString {get; set;}
You can also get the full property typing "propfull" and then tab twice. That would generate the field and the full property.
private int myVar;
public int MyProperty
{
get { return myVar;}
set { myVar = value;}
}
This will do what you need in almost any situation, is customizable with optional arguments, and as you can see, is pretty much self-documenting:
from math import log
def pretty_size(n,pow=0,b=1024,u='B',pre=['']+[p+'i'for p in'KMGTPEZY']):
pow,n=min(int(log(max(n*b**pow,1),b)),len(pre)-1),n*b**pow
return "%%.%if %%s%%s"%abs(pow%(-pow-1))%(n/b**float(pow),pre[pow],u)
Example output:
>>> pretty_size(42)
'42 B'
>>> pretty_size(2015)
'2.0 KiB'
>>> pretty_size(987654321)
'941.9 MiB'
>>> pretty_size(9876543210)
'9.2 GiB'
>>> pretty_size(0.5,pow=1)
'512 B'
>>> pretty_size(0)
'0 B'
Advanced customizations:
>>> pretty_size(987654321,b=1000,u='bytes',pre=['','kilo','mega','giga'])
'987.7 megabytes'
>>> pretty_size(9876543210,b=1000,u='bytes',pre=['','kilo','mega','giga'])
'9.9 gigabytes'
This code is both Python 2 and Python 3 compatible. PEP8 compliance is an exercise for the reader. Remember, it's the output that's pretty.
Update:
If you need thousands commas, just apply the obvious extension:
def prettier_size(n,pow=0,b=1024,u='B',pre=['']+[p+'i'for p in'KMGTPEZY']):
r,f=min(int(log(max(n*b**pow,1),b)),len(pre)-1),'{:,.%if} %s%s'
return (f%(abs(r%(-r-1)),pre[r],u)).format(n*b**pow/b**float(r))
For example:
>>> pretty_units(987654321098765432109876543210)
'816,968.5 YiB'
Simply type ctor
then press TAB.

If you're going to work with regular expressions a lot, I'd suggest bookmarking that site, it's very useful.
Try this (the negative in front of the x is valid since it is a unary operator, find more here):
int answer = -x;
With this, you can turn a positive to a negative and a negative to a positive.
However, if you want to only make a negative number positive then try this:
int answer = Math.abs(x);
A little cool math trick! Squaring the number will guarantee a positive value of x^2, and then, taking the square root will get you to the absolute value of x:
int answer = Math.sqrt(Math.pow(x, 2));
Hope it helps! Good Luck!
My solution with ramda js:
const testString = 'somestringtotest'
const countLetters = R.compose(
R.map(R.length),
R.groupBy(R.identity),
R.split('')
)
countLetters(testString)
Have you thought about using Python list's .index(value)
method? It return the index in the list of where the first instance of the value
passed in is found.
A more concise version
IF COL_LENGTH('table_name','column_name') IS NULL
BEGIN
/* Column does not exist or caller does not have permission to view the object */
END
The point about permissions on viewing metadata applies to all answers not just this one.
Note that the first parameter table name to COL_LENGTH
can be in one, two, or three part name format as required.
An example referencing a table in a different database is
COL_LENGTH('AdventureWorks2012.HumanResources.Department','ModifiedDate')
One difference with this answer compared to using the metadata views is that metadata functions such as COL_LENGTH
always only return data about committed changes irrespective of the isolation level in effect.
I recommend you to use an unordered list for your image gallery.
You should use my code unless you want the image to gain instantly 50% opacity after you hover out. You will have a smoother transition.
#photos li {
opacity: .5;
transition: opacity .5s ease-out;
-moz-transition: opacity .5s ease-out;
-webkit-transition: opacity .5s ease-out;
-o-transition: opacity .5s ease-out;
}
#photos li:hover {
opacity: 1;
}
In visual studio 2017 please do following steps:

Hope its working...
Because "append" existed long before "pop" was thought of. Python 0.9.1 supported list.append in early 1991. By comparison, here's part of a discussion on comp.lang.python about adding pop in 1997. Guido wrote:
To implement a stack, one would need to add a list.pop() primitive (and no, I'm not against this particular one on the basis of any principle). list.push() could be added for symmetry with list.pop() but I'm not a big fan of multiple names for the same operation -- sooner or later you're going to read code that uses the other one, so you need to learn both, which is more cognitive load.
You can also see he discusses the idea of if push/pop/put/pull should be at element [0] or after element [-1] where he posts a reference to Icon's list:
I stil think that all this is best left out of the list object implementation -- if you need a stack, or a queue, with particular semantics, write a little class that uses a lists
In other words, for stacks implemented directly as Python lists, which already supports fast append(), and del list[-1], it makes sense that list.pop() work by default on the last element. Even if other languages do it differently.
Implicit here is that most people need to append to a list, but many fewer have occasion to treat lists as stacks, which is why list.append came in so much earlier.
Here's a good metrics plugin that displays number of lines of code and much more:

Any JS code which executes and deals with DOM elements should execute after the DOM elements have been created. JS code is interpreted from top to down as layed out in the HTML. So, if there is a tag before the DOM elements, the JS code within script tag will execute as the browser parses the HTML page.
So, in your case, you can put your DOM interacting code inside a function so that only function is defined but not executed.
Then you can add an event listener for document load to execute the function.
That will give you something like:
<script>
function init() {
var myButton = document.getElementById("myButton");
var myTextfield = document.getElementById("myTextfield");
myButton.onclick = function() {
var userName = myTextfield.value;
greetUser(userName);
}
}
function greetUser(userName) {
var greeting = "Hello " + userName + "!";
document.getElementsByTagName ("h2")[0].innerHTML = greeting;
}
document.addEventListener('readystatechange', function() {
if (document.readyState === "complete") {
init();
}
});
</script>
<h2>Hello World!</h2>
<p id="myParagraph">This is an example website</p>
<form>
<input type="text" id="myTextfield" placeholder="Type your name" />
<input type="button" id="myButton" value="Go" />
</form>

Consider the below definition in web.xml
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>TestServlet</servlet-class>
<init-param>
<param-name>myprop</param-name>
<param-value>value</param-value>
</init-param>
</servlet>
You can see that init-param is defined inside a servlet element. This means it is only available to the servlet under declaration and not to other parts of the web application. If you want this parameter to be available to other parts of the application say a JSP this needs to be explicitly passed to the JSP. For instance passed as request.setAttribute(). This is highly inefficient and difficult to code.
So if you want to get access to global values from anywhere within the application without explicitly passing those values, you need to use Context Init parameters.
Consider the following definition in web.xml
<web-app>
<context-param>
<param-name>myprop</param-name>
<param-value>value</param-value>
</context-param>
</web-app>
This context param is available to all parts of the web application and it can be retrieved from the Context object. For instance, getServletContext().getInitParameter(“dbname”);
From a JSP you can access the context parameter using the application implicit object. For example, application.getAttribute(“dbname”);
For Linux servers you just need one line of code to copy recursively while preserving permission:
exec('cp -a '.$source.' '.$dest);
Another way of doing it is:
mkdir($dest);
foreach ($iterator = new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($source, \RecursiveDirectoryIterator::SKIP_DOTS), \RecursiveIteratorIterator::SELF_FIRST) as $item)
{
if ($item->isDir())
mkdir($dest.DIRECTORY_SEPARATOR.$iterator->getSubPathName());
else
copy($item, $dest.DIRECTORY_SEPARATOR.$iterator->getSubPathName());
}
but it's slower and does not preserve permissions.
This is still a matplotlib object. Try this:
# <your code here>
locs, labels = plt.xticks()
plt.setp(labels, rotation=45)
Create your own container:
template <class T>
class statList : public std::list<T>
{
public:
statList() : std::list<T>::list() {}
~statList() {}
T mean() {
return accumulate(begin(),end(),0.0)/size();
}
T stddev() {
T diff_sum = 0;
T m = mean();
for(iterator it= begin(); it != end(); ++it)
diff_sum += ((*it - m)*(*it -m));
return diff_sum/size();
}
};
It does have some limitations, but it works beautifully when you know what you are doing.

I came here looking for a possible explanation before taking a closer look at the lines preceding the linker error. It turned out to have been an additional executable for which the global declaration was missing!
Or you could use the sugar.js library, and the format method:
format( place = 0 , thousands = ',' , decimal = '.' ) Formats the number to a readable string. If place is undefined, will automatically determine the place. thousands is the character used for the thousands separator. decimal is the character used for the decimal point.
Examples:
(56782).format() > "56,782"
(56782).format(2) > "56,782.00"
(4388.43).format(2, ' ') > "4 388.43"
(4388.43).format(3, '.', ',') > "4.388,430"
$(this).find('td')
will give you an array of td's in the tr.
$(document).height() seems to do the trick and gives the total height including the area which is only visible through scrolling.
The cex
parameter will do that for you.
a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
col = 1:6, space = c(0, 2))
legend("topright",
legend = c("a", "b", "c", "d", "e", "f"),
fill = 1:6, ncol = 2,
cex = 0.75)
Here is a way to do it for Django users:
from django.core.management.base import BaseCommand
from django.db import connections
class Command(BaseCommand):
def handle(self, database="default", *args, **options):
cursor = connections[database].cursor()
cursor.execute("SHOW TABLE STATUS");
for row in cursor.fetchall():
if row[1] != "InnoDB":
print "Converting %s" % row[0],
result = cursor.execute("ALTER TABLE %s ENGINE=INNODB" % row[0])
print result
Add that to your app under the folders management/commands/ Then you can convert all your tables with a manage.py command:
python manage.py convert_to_innodb
I think you shouldn't prepend themesDir
. You only pass the filename of the template to flask, it will then look in a folder called templates
relative to your python file.
I would:
for _ in range(3):
do()
The _
is convention for a variable whose value you don't care about.
You might also see some people write:
[do() for _ in range(3)]
however that is slightly more expensive because it creates a list containing the return values of each invocation of do()
(even if it's None
), and then throws away the resulting list. I wouldn't suggest using this unless you are using the list of return values.
function curl_int(); cause server error,install sudo apt-get install php5-curl restart apache2 server .. it will work like charm
Not sure if this is problem but, this ticked me off for a while since I did not realize what was happening at first - maybe this will help others.
Its not really a problem, just the way Eclipse works. (I'm use to Visual studio) Its all about Perspectives!
I set up an (existing) PHP project in eclipse(neon) and then tried to configure and run debug. A Popup "Confirm Perspective Switch" is shown - I selected "Yes", not realizing what it actually does. The "perspective" then changes and you no longer see the project explorer anywhere. You cant "open" the project explorer window from top nav > window > show view, since its no longer there (which is BS, it should show something that gives you indication of current and other "perspectives" - at least for newbie.) No where now does it give project explore options.
Now you must change the "perspective" back from debug to PHP (at least in in my case).
This can be done a couple ways, easiest is from the icons on right top right side side. One icon would be the "bug", and next to it is the PHP icon. Just click the icon "perspective" you want. The other way is from top nav bar > window > Perspective > open Perspective, then select PHP. Could they hide this any deeper?
I know this is likely second nature to those who have used eclipse for a while, but was frustrating to me (on day one) till I figured out what was going on.
On Windows you can use the following command.
start javaw -jar JarFile.jar
By doing so, the Command Prompt Window doesn't stay open.

A quick way to do it in sql server 2012 is as follows:
SELECT FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss')
This is the only install that resolved the issue for me.
SQL 2008 r2 w/ office 2010 64bit: "2007 Office System Driver: Data Connectivity Components"
If you can restrict it to just (Open Office XML format) *.xlsx files, then probably the most popular library would be EPPLus.
Bonus is, there are no other dependencies. Just install using nuget:
Install-Package EPPlus
<%= Html.Partial("PartialName", Model) %>
If you're not sure what you're doing, use the '=='. If you have a little more knowledge about it you can use 'is' for known objects like 'None'.
Otherwise you'll end up wondering why things doesn't work and why this happens:
>>> a = 1
>>> b = 1
>>> b is a
True
>>> a = 6000
>>> b = 6000
>>> b is a
False
I'm not even sure if some things are guaranteed to stay the same between different python versions/implementations.
Sorry to jump on this question late in the game but I have an answer for irregular (non-rectangular) shapes. I solved it using SVGs to generate masks of where I want to have the event attached.
The idea is to attach events to inlined SVGs, super cheap and even user friendly because there are plenty of programs for generating SVGs. The SVG can have a layer of the image as a background.
http://jcrogel.com/code/2015/03/18/mapping-images-using-javascript-events/
In plain-old JavaScript you can do this:
var inputs = document.getElementsByTagName('input');
for(var i = 0; i < inputs.length; i++) {
if(inputs[i].type.toLowerCase() == 'text') {
alert(inputs[i].value);
}
}
In jQuery, you would just do:
// select all inputs of type 'text' on the page
$("input:text")
// hide all text inputs which are descendants of div class="foo"
$("div.foo input:text").hide();
In my case it worked great just by doing the following:
[HttpPost]
public ActionResult DoSomething(int custNum)
{
// Some magic code here...
}
<form id="frmSomething" method="post">
<div>
<!-- Some magic html here... -->
</div>
<button id="btnSubmit" type="submit">Submit</button>
</form>
var frmSomething= $("#frmSomething");
var btnSubmit= $("#btnSubmit");
var custNum = 100;
btnSubmit.click(function()
{
frmSomething.attr("action", "/Home/DoSomething?custNum=" + custNum);
btnSubmit.submit();
});
Hope this helps vatos!

If you remove directives attribute it should work.
@Component({
selector: 'parent',
template: `

export class ParentComponent{}
@Component({

template: `
<h4>Child Component</h4>
`
})
export class ChildComponent{}
Directives are like components but they are used in attributes. They also have a declarator @Directive
. You can read more about directives Structural Directives and Attribute Directives.
There are two other kinds of Angular directives, described extensively elsewhere: (1) components and (2) attribute directives.
A component manages a region of HTML in the manner of a native HTML element. Technically it's a directive with a template.
Also if you are open the glossary you can find that components are also directives.
Directives fall into one of the following categories:
Components combine application logic with an HTML template to render application views. Components are usually represented as HTML elements. They are the building blocks of an Angular application.
Attribute directives can listen to and modify the behavior of other HTML elements, attributes, properties, and components. They are usually represented as HTML attributes, hence the name.
Structural directives are responsible for shaping or reshaping HTML layout, typically by adding, removing, or manipulating elements and their children.
The difference that components have a template. See Angular Architecture overview.
A directive is a class with a
@Directive
decorator. A component is a directive-with-a-template; a@Component
decorator is actually a@Directive
decorator extended with template-oriented features.
The @Component
metadata doesn't have directives
attribute. See Component decorator.

The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5
. From the comment you put this needed to be declared elsewhere in your code

Try this,
add inplace=True

df.replace(np.NaN, ' ', inplace=True)
Like others, the accepted answer also gave me an outdated version.
Here is another way to do it that works very well:
$ curl --silent --location https://rpm.nodesource.com/setup_14.x | bash -
$ yum -y install nodejs
You can also replace the 14.x with another version, such as 12.x, 10.x, etc.
You can see all available versions on the NodeSource Github page, and pull from there as well if desired.
Note: you may need to run using sudo
depending on your environment.

Before starting your download check your runtime permissions and if you don't have permission the request permissions like this method
requestStoragePermission()
private void requestStoragePermission(){
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
android.Manifest.permission.READ_EXTERNAL_STORAGE))
{
}
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
STORAGE_PERMISSION_CODE);
}
@Override
public void onRequestPermissionsResult(int requestCode,
@NonNull String[] permissions,
@NonNull int[] grantResults) {
if(requestCode == STORAGE_PERMISSION_CODE){
if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
}
else{
Toast.makeText(this,
"Oops you just denied the permission",
Toast.LENGTH_LONG).show();
}
}
}
I have the following call:
$('#select_box_id').change(function() {
var action = $('#my_form').attr('action');
$.get(action,{},function(response){
$.each(response.result,function(i) {
alert("key is: " + i + ", val is: " + response.result[i]);
});
}, 'json');
});
The structure coming back from the server look like:
{"result":{"1":"waterskiing","2":"canoeing","18":"windsurfing"}}
Assuming you want the full object, but only want to deal with distinctness by typeID
, there's nothing built into LINQ to make this easy. (If you just want the typeID
values, it's easy - project to that with Select
and then use the normal Distinct
call.)
In MoreLINQ we have the DistinctBy
operator which you could use:
var distinct = list.DistinctBy(x => x.typeID);
This only works for LINQ to Objects though.
You can use a grouping or a lookup, it's just somewhat annoying and inefficient:
var distinct = list.GroupBy(x => x.typeID, (key, group) => group.First());
This is how to set an image into ImageView
using the setImageResource() method:
ImageView myImageView = (ImageView)v.findViewById(R.id.img_play);

myImageView.setImageResource(R.drawable.ic_play);
Some applications may detect click source at low OS level. If you really need that kind of hack, you may just run target app in virtual machine's window, and run cliker in host OS, it can help.
When you pass a lambda
to sort
, you need to return an integer, not a boolean. So your code should instead read as follows:
xs.sort(lambda x,y: cmp(len(x), len(y)))
Note that cmp is a builtin function such that cmp(x, y)
returns -1 if x
is less than y
, 0 if x
is equal to y
, and 1 if x
is greater than y
.
Of course, you can instead use the key
parameter:
xs.sort(key=lambda s: len(s))
This tells the sort
method to order based on whatever the key function returns.
EDIT: Thanks to balpha and Ruslan below for pointing out that you can just pass len
directly as the key parameter to the function, thus eliminating the need for a lambda
:
xs.sort(key=len)
And as Ruslan points out below, you can also use the built-in sorted function rather than the list.sort
method, which creates a new list rather than sorting the existing one in-place:
print(sorted(xs, key=len))
You can check detail of error by running this command
sudo service mongod status

I needed to start/stop background music in my application when first activity opens and closes or when any activity is paused by home button and then resumed from task manager. Pure playback stopping/resuming in Activity.onPause()
and Activity.onResume()
interrupted the music for a while, so I had to write the following code:
@Override
public void onResume() {
super.onResume();
// start playback here (if not playing already)
}
@Override
public void onPause() {
super.onPause();
ActivityManager manager = (ActivityManager) this.getSystemService(Activity.ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> tasks = manager.getRunningTasks(Integer.MAX_VALUE);
boolean is_finishing = this.isFinishing();
boolean is_last = false;
boolean is_topmost = false;
for (ActivityManager.RunningTaskInfo task : tasks) {
if (task.topActivity.getPackageName().startsWith("cz.matelier.skolasmyku")) {
is_last = task.numRunning == 1;
is_topmost = task.topActivity.equals(this.getComponentName());
break;
}
}
if ((is_finishing && is_last) || (!is_finishing && is_topmost && !mIsStarting)) {
mIsStarting = false;
// stop playback here
}
}
which interrupts the playback only when application (all its activities) is closed or when home button is pressed. Unfortunatelly I didn't manage to change order of calls of onPause()
method of the starting activity and onResume()
of the started actvity when Activity.startActivity()
is called (or detect in onPause()
that activity is launching another activity other way) so this case have to be handled specially:
private boolean mIsStarting;
@Override
public void startActivity(Intent intent) {
mIsStarting = true;
super.startActivity(intent);
}
Another drawback is that this requires GET_TASKS
permission added to AndroidManifest.xml
:
<uses-permission
android:name="android.permission.GET_TASKS"/>
Modifying this code that it only reacts on home button press is straighforward.
Adding another entry for the debate about whether batch normalization should be called before or after the non-linear activation:
In addition to the original paper using batch normalization before the activation, Bengio's book Deep Learning, section 8.7.1 gives some reasoning for why applying batch normalization after the activation (or directly before the input to the next layer) may cause some issues:
It is natural to wonder whether we should apply batch normalization to the input X, or to the transformed value XW+b. Io?e and Szegedy (2015) recommend the latter. More speci?cally, XW+b should be replaced by a normalized version of XW. The bias term should be omitted because it becomes redundant with the ß parameter applied by the batch normalization reparameterization. The input to a layer is usually the output of a nonlinear activation function such as the recti?ed linear function in a previous layer. The statistics of the input are thus more non-Gaussian and less amenable to standardization by linear operations.
In other words, if we use a relu activation, all negative values are mapped to zero. This will likely result in a mean value that is already very close to zero, but the distribution of the remaining data will be heavily skewed to the right. Trying to normalize that data to a nice bell-shaped curve probably won't give the best results. For activations outside of the relu family this may not be as big of an issue.
Keep in mind that there are reports of models getting better results when using batch normalization after the activation, while others get best results when the batch normalization is placed before the activation. It is probably best to test your model using both configurations, and if batch normalization after activation gives a significant decrease in validation loss, use that configuration instead.

Hibernate also is picky about the capitalization. By default it's going to be the class name with the First letter Capitalized. So if your class is called FooBar
, don't pass "foobar"
. You have to pass "FooBar"
with that exact capitalization for it to work.
I feel this question (which I get quite a bit) is best answered with an analogy.
Many of us lift weights. Why? Is it because we're preparing for that day when we become a professional weightlifter? Will we ever encounter the lifting of weights as a job requirement?
Of course not. We lift weights because it exercises our muscles. It keeps us fit and in shape. A fit person will perform better in other areas: hiking, construction, running, sleeping, etc.
Learning mathematics is like weightlifting for the brain. It exercises the mind and keeps it in shape. You may never use calculus in your career, but your brain will be in better shape because of it.
The command you're looking for is rem
, short for "remark".
There is also a shorthand version ::
that some people use, and this sort of looks like #
if you squint a bit and look at it sideways. I originally preferred that variant since I'm a bash
-aholic and I'm still trying to forget the painful days of BASIC :-)
Unfortunately, there are situations where ::
stuffs up the command line processor (such as within complex if
or for
statements) so I generally use rem
nowadays. In any case, it's a hack, suborning the label infrastructure to make it look like a comment when it really isn't. For example, try replacing rem
with ::
in the following example and see how it works out:
if 1==1 (
rem comment line 1
echo 1 equals 1
rem comment line 2
)
You should also keep in mind that rem
is a command, so you can't just bang it at the end of a line like the #
in bash
. It has to go where a command would go. For example, only the second of these two will echo the single word hello
:
echo hello rem a comment.
echo hello & rem a comment.
You can do something like:
Directory directory = new DirectoryInfo(path);
List<FileInfo> fileInfos = directory.EnumerateFiles("*.*", SearchOption.AllDirectories).ToList();
foreach (FileInfo f in fileInfos)
File.Delete(f.FullName);
For remove in NestJS need to add option to Shema() decorator

{
Form2 f2 = new Form2();
f2.ShowDialog();
MessageBox.Show("Form1 Message :"+Form2.t.Text); //can put label also in form 1 to show the value got from form2
}
Form2 Code :
public Form2()
{
InitializeComponent();
t = textBox1; //Initialize with static textbox
}
public static TextBox t=new TextBox(); //make static to get the same value as inserted
private void button1_Click(object sender, EventArgs e)

Download numpy-1.9.2+mkl-cp27-none-win32.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy .
Copy the file to C:\Python27\Scripts
Run cmd from the above location and type
pip install numpy-1.9.2+mkl-cp27-none-win32.whl
You will hopefully get the below output:

Hope that works for you.
EDIT 1
Adding @oneleggedmule 's suggestion:
You can also run the following command in the cmd:
pip2.7 install numpy-1.9.2+mkl-cp27-none-win_amd64.whl
Basically, writing pip alone also works perfectly (as in the original answer). Writing the version 2.7 can also be done for the sake of clarity or specification.

I get this error when I open a new project with VS Code & Flutter. I solved the problem by editing the gradle.build and gradle-wrapper.properties files.

It's hard to say because the actual behaviour is different between different compilers/runtimes. Even debug/release builds have different behaviour. Debug builds of VS2005 will insert markers between allocations to detect memory corruption, so instead of a crash, it will assert in free().

From this link http://www.svennerberg.com/2009/09/google-maps-api-3-infowindows/:
Teo: The easiest way to do this is to just have one instance of the InfoWindow object that you reuse over and over again. That way when you click a new marker the infoWindow is “moved” from where it’s currently at, to point at the new marker.
Use its setContent method to load it with the correct content.
add the file info.php to the following directory - your default http/apache directory - normally /var/www/html
with the following contents
<?php
phpinfo();
?>
Then httpd/apache restart the go to your default html directory http://enter.server.here/info.php
would deliver the whole php pedigree!

The algorithm that Git uses when calculating diff's to be reverted requires that
The definition of "adjacent" is based on the default number of lines from a context diff, which is 3. So if 'myfile' was constructed like this:
$ cat >myfile <<EOF
line 1
junk
junk
junk
junk
line 2
junk
junk
junk
junk
line 3
EOF
$ git add myfile
$ git commit -m "initial check-in"
1 files changed, 11 insertions(+), 0 deletions(-)
create mode 100644 myfile
$ perl -p -i -e 's/line 2/this is the second line/;' myfile
$ git commit -am "changed line 2 to second line"
[master d6cbb19] changed line 2
1 files changed, 1 insertions(+), 1 deletions(-)
$ perl -p -i -e 's/line 3/this is the third line/;' myfile
$ git commit -am "changed line 3 to third line"
[master dd054fe] changed line 3
1 files changed, 1 insertions(+), 1 deletions(-)
$ git revert d6cbb19
Finished one revert.
[master 2db5c47] Revert "changed line 2"
1 files changed, 1 insertions(+), 1 deletions(-)
Then it all works as expected.
The second answer was very interesting. There is a feature which has not yet been officially released (though it is available in Git v1.7.2-rc2) called Revert Strategy. You can invoke git like this:
git revert --strategy resolve <commit>
and it should do a better job figuring out what you meant. I do not know what the list of available strategies is, nor do I know the definition of any strategy.
You can build a small UI that does the job like this :
function test(){
showURL("http://www.google.com")
}
//
function showURL(href){
var app = UiApp.createApplication().setHeight(50).setWidth(200);
app.setTitle("Show URL");
var link = app.createAnchor('open ', href).setId("link");
app.add(link);
var doc = SpreadsheetApp.getActive();
doc.show(app);
}
If you want to 'show' the URL, just change this line like this :
var link = app.createAnchor(href, href).setId("link");
EDIT : link to a demo spreadsheet in read only because too many people keep writing unwanted things on it (just make a copy to use instead).
EDIT : UiApp was deprecated by Google on 11th Dec 2014, this method could break at any time and needs updating to use HTML service instead!
EDIT : below is an implementation using html service.
function testNew(){
showAnchor('Stackoverflow','http://stackoverflow.com/questions/tagged/google-apps-script');
}
function showAnchor(name,url) {
var html = '<html><body><a href="'+url+'" target="blank" onclick="google.script.host.close()">'+name+'</a></body></html>';
var ui = HtmlService.createHtmlOutput(html)
SpreadsheetApp.getUi().showModelessDialog(ui,"demo");
}
The this
keyword is primarily used in three situations. The first and most common is in setter methods to disambiguate variable references. The second is when there is a need to pass the current class instance as an argument to a method of another object. The third is as a way to call alternate constructors from within a constructor.
Case 1: Using this
to disambiguate variable references. In Java setter methods, we commonly pass in an argument with the same name as the private member variable we are attempting to set. We then assign the argument x
to this.x
. This makes it clear that you are assigning the value of the parameter "name" to the instance variable "name".
public class Foo
{
private String name;
public void setName(String name) {
this.name = name;
}
}
Case 2: Using this
as an argument passed to another object.
public class Foo
{
public String useBarMethod() {
Bar theBar = new Bar();
return theBar.barMethod(this);
}
public String getName() {
return "Foo";
}
}
public class Bar
{
public void barMethod(Foo obj) {
obj.getName();
}
}
Case 3: Using this
to call alternate constructors. In the comments, trinithis correctly pointed out another common use of this
. When you have multiple constructors for a single class, you can use this(arg0, arg1, ...)
to call another constructor of your choosing, provided you do so in the first line of your constructor.
class Foo
{
public Foo() {
this("Some default value for bar");
//optional other lines
}
public Foo(String bar) {
// Do something with bar
}
}
I have also seen this
used to emphasize the fact that an instance variable is being referenced (sans the need for disambiguation), but that is a rare case in my opinion.
Because
$.ajax({type: "POST" - calls OPTIONS
$.post( - Calls POST
Both are different. Postman calls "POST" properly, but when we call it, it will be "OPTIONS".
For C# web services - Web API

If your browser supports CSS3, try using the CSS element Calc()
height: calc(100% - 65px);
you might also want to adding browser compatibility options:
height: -o-calc(100% - 65px); /* opera */
height: -webkit-calc(100% - 65px); /* google, safari */
height: -moz-calc(100% - 65px); /* firefox */
also make sure you have spaces between values, see: https://stackoverflow.com/a/16291105/427622
I try to use a union to combine two queries to format the returns you want:
SELECT recordid, startdate, enddate FROM tmp
Where enddate is null
UNION
SELECT recordid, MIN(startdate), MAX(enddate) FROM tmp GROUP BY recordid
But I have no idea if the Union would have great impact on the performance
You can achieve this is to combine For XML Path and STUFF as follows:
SELECT (STUFF((
SELECT ', ' + StringValue
FROM Jira.customfieldvalue
WHERE CUSTOMFIELD = 12534
AND ISSUE = 19602
FOR XML PATH('')
), 1, 2, '')
) AS StringValue
an even simpler solution is:
df = df.reindex(columns = header_list)
where "header_list" is a list of the headers you want to appear.
any header included in the list that is not found already in the dataframe will be added with blank cells below.
so if
header_list = ['a','b','c', 'd']
then c and d will be added as columns with blank cells
The selected answer would work for as long as you know the key itself that you want to delete but if it should be truly dynamic you would need to use the [] notation instead of the dot notation.
For example:
var keyToDelete = "key1";
var myObj = {"test": {"key1": "value", "key2": "value"}}
//that will not work.
delete myObj.test.keyToDelete
instead you would need to use:
delete myObj.test[keyToDelete];
Substitute the dot notation with [] notation for those values that you want evaluated before being deleted.
In SQL Server Management Studio query window
Not sure if this is what you mean, but try setting las=1
. Here's an example:
require(grDevices)
tN <- table(Ni <- stats::rpois(100, lambda=5))
r <- barplot(tN, col=rainbow(20), las=1)
That represents the style of axis labels. (0=parallel, 1=all horizontal, 2=all perpendicular to axis, 3=all vertical)
SELECT *, 1 AS sort_order
FROM table1
EXCEPT
SELECT *, 1 AS sort_order
FROM table2
UNION
SELECT *, 1 AS sort_order
FROM table1
INTERSECT
SELECT *, 1 AS sort_order
FROM table2
UNION
SELECT *, 2 AS sort_order
FROM table2
EXCEPT
SELECT *, 2 AS sort_order
FROM table1
ORDER BY sort_order;
But the real answer is: other than the ORDER BY
clause, the sort order will by arbitrary and not guaranteed.
This should work in MySql
SELECT * FROM 'my_table' WHERE 'month' = MONTH(CURRENT_TIMESTAMP) AND 'year' = YEAR(CURRENT_TIMESTAMP);
It's probably easiest to create your query object directly as:
Test.find({
$and: [
{ $or: [{a: 1}, {b: 1}] },
{ $or: [{c: 1}, {d: 1}] }
]
}, function (err, results) {
...
}
But you can also use the Query#and
helper that's available in recent 3.x Mongoose releases:
Test.find()
.and([
{ $or: [{a: 1}, {b: 1}] },
{ $or: [{c: 1}, {d: 1}] }
])
.exec(function (err, results) {
...
});
If you simply open the file for writing with the truncate-option, you'll delete the content.
std::ofstream ofs;
ofs.open("test.txt", std::ofstream::out | std::ofstream::trunc);
ofs.close();
Although this isn't going to be a problem for the person who asked the question, because they ran the program that was to produce the core file in a script with the ulimit command, I'd like to document that the ulimit command is specific to the shell in which you run it (like environment variables). I spent way too much time running ulimit and sysctl and stuff in one shell, and the command that I wanted to dump core in the other shell, and wondering why the core file was not produced.
I will be adding it to my bashrc. The sysctl works for all processes once it is issued, but the ulimit only works for the shell in which it is issued (maybe also the descendents too) - but not for other shells that happen to be running.
You can use Like
if(condition1 || condition2 || condition3 || ..........)
{
enter code here
}
Will it warn you if you pass a 32-bit unsigned integer to a %lu format? It should be fine since the conversion is well-defined and doesn't lose any information.

Difference between a Spy and a Mock
When Mockito creates a mock – it does so from the Class of a Type, not from an actual instance. The mock simply creates a bare-bones shell instance of the Class, entirely instrumented to track interactions with it. On the other hand, the spy will wrap an existing instance. It will still behave in the same way as the normal instance – the only difference is that it will also be instrumented to track all the interactions with it.
In the following example – we create a mock of the ArrayList class:
@Test
public void whenCreateMock_thenCreated() {
List mockedList = Mockito.mock(ArrayList.class);
mockedList.add("one");
Mockito.verify(mockedList).add("one");
assertEquals(0, mockedList.size());
}
As you can see – adding an element into the mocked list doesn’t actually add anything – it just calls the method with no other side-effect. A spy on the other hand will behave differently – it will actually call the real implementation of the add method and add the element to the underlying list:
@Test
public void whenCreateSpy_thenCreate() {
List spyList = Mockito.spy(new ArrayList());
spyList.add("one");
Mockito.verify(spyList).add("one");
assertEquals(1, spyList.size());
}
Here we can surely say that the real internal method of the object was called because when you call the size() method you get the size as 1, but this size() method isn’t been mocked! So where does 1 come from? The internal real size() method is called as size() isn’t mocked (or stubbed) and hence we can say that the entry was added to the real object.

Iliya,
Sorry for that.
you code is work. but its had some problem with Array row and columns
here i correct your code this work correctly, you can try this ..
public static void printMatrix(int size, int row, int[][] matrix) {
for (int i = 0; i < 7 * matrix[row].length; i++) {
System.out.print("-");
}
System.out.println("-");
for (int i = 1; i <= matrix[row].length; i++) {
System.out.printf("| %4d ", matrix[row][i - 1]);
}
System.out.println("|");
if (row == size - 1) {
// when we reach the last row,
// print bottom line "---------"
for (int i = 0; i < 7 * matrix[row].length; i++) {
System.out.print("-");
}
System.out.println("-");
}
}
public static void length(int[][] matrix) {
int rowsLength = matrix.length;
for (int k = 0; k < rowsLength; k++) {
printMatrix(rowsLength, k, matrix);
}
}
public static void main(String[] args) {
int[][] matrix = { { 1, 2, 5 }, { 3, 4, 6 }, { 7, 8, 9 }
};
length(matrix);
}
and out put look like
----------------------
| 1 | 2 | 5 |
----------------------
| 3 | 4 | 6 |
----------------------
| 7 | 8 | 9 |

$("#layout_select")
.find("option")
.show()
.not("option[value*='" + this.value + "']").hide();
$("#layout_select").val(

}).change();
(assuming the third option
should have a value col3
)
Example: http://jsfiddle.net/cL2tt/
Notes:
.change()
event to define an event handler that executes when the value of select#column_select
changes..show()
all option

..hide()
all option
s in the second select
whose value
does not contain the value
of the selected option in select#column_select
, using the attribute contains selector.If you run "dir c:\

If you are using moment then you can use their "official plugin" for ranges moment-range
and then this becomes trivial.
moment-range node example:
const Moment = require('moment');
const MomentRange = require('moment-range');
const moment = MomentRange.extendMoment(Moment);
const start = new Date("11/30/2018"), end = new Date("09/30/2019")
const range = moment.range(moment(start), moment(end));
console.log(Array.from(range.by('day')))
moment-range browser example:
window['moment-range'].extendMoment(moment);_x000D_
_x000D_
const start = new Date("11/30/2018"), end = new Date("09/30/2019")_x000D_

Using !important
is generally not a good idea in the code itself, but it can be useful in various overrides.
I use Firefox and a dotjs plugin which essentially can run your own custom JS or CSS code on specified websites automatically.
Here's the code for it I use on Twitter that makes the tweet input field always stay on my screen no matter how far I scroll, and for the hyperlinks to always remain the same color.
a, a * {
color: rgb(34, 136, 85) !important;
}
.count-inner {
color: white !important;
}
.timeline-tweet-box {
z-index: 99 !important;
position: fixed !important;
left: 5% !important;
}
Since, thankfully, Twitter developers don't use !important
properties much, I can use it to guarantee that the specified styles will be definitely overridden, because without !important
they were not overridden sometimes. It really came in handy for me there.

The accepted answer changes shape for 2d arrays.
I present a solution here, using the Pandas dropna() functionality.
It works for 1D and 2D arrays. In the 2D case you can choose weather to drop the row or column containing np.nan
.
import pandas as pd
import numpy as np
def dropna(arr, *args, **kwarg):
assert isinstance(arr, np.ndarray)
dropped=pd.DataFrame(arr).dropna(*args, **kwarg).values
if arr.ndim==1:
dropped=dropped.flatten()
return dropped
x = np.array([1400, 1500, 1600, np.nan, np.nan, np.nan ,1700])
y = np.array([[1400, 1500, 1600], [np.nan, 0, np.nan] ,[1700,1800,np.nan]] )
print('='*20+' 1D Case: ' +'='*20+'\nInput:\n',x,sep='')
print('\ndropna:\n',dropna(x),sep='')
print('\n\n'+'='*20+' 2D Case: ' +'='*20+'\nInput:\n',y,sep='')
print('\ndropna (rows):\n',dropna(y),sep='')
print('\ndropna (columns):\n',dropna(y,axis=1),sep='')
print('\n\n'+'='*20+' x[np.logical_not(np.isnan(x))] for 2D: ' +'='*20+'\nInput:\n',y,sep='')
print('\ndropna:\n',x[np.logical_not(np.isnan(x))],sep='')
Result:
==================== 1D Case: ====================
Input:
[1400. 1500. 1600. nan nan nan 1700.]
dropna:

My case was that I had a typo on the referred column:
MariaDB [blog]> alter table t_user add FOREIGN KEY ( country_code ) REFERENCES t_country ( coutry_code );
ERROR 1005 (HY000): Can't create table `blog`.`t_user` (errno: 150 "Foreign key constraint is incorrectly formed")
The error message is quite cryptic and I've tried everything - verifying the types of the columns, collations, engines, etc.
It took me awhile to note the typo and after fixing it all worked fine:

The problem is with the input.nextInt() method - it only reads the int value. So when you continue reading with input.nextLine() you receive the "\n" Enter key. So to skip this you have to add the input.nextLine(). Hope this should be clear now.
Try it like that:
System.out.print("Insert a number: ");
int number = input.nextInt();
input.nextLine(); // This line you have to add (It consumes the \n character)
System.out.print("Text1: ");
String text1 = input.nextLine();
System.out.print("Text2: ");
String text2 = input.nextLine();
Maybe too late now, but more often than not you need to run
aspnet_regiis.exe -i
after installing asp.net. Maybe I would do it anyway now.

to send output to the output window in your IDE.
Edit: In regards to the problem, have you verified your mainForm_Load
is actually being called? You could place a breakpoint at the beginning of mainForm_Load
to see. If it is not being called, I suspect that mainForm_Load
is not hooked up to the Load
event.
Also, it is more efficient and generally better to override On{EventName}
instead of subscribing to {EventName}
from within derived classes (in your case overriding OnLoad
instead of Load
).
Use reverse(...)
methods of java.util.Collections

I got exactly the same error in Windows 8 while trying to export decision tree digraph using tree.export_graphviz! Then I installed GraphViz from this link. And then I followed the below steps which resolved my issue:
Here is an example of a recursive algorithm for reversing a singly linked list. On a laptop with the following spec (4G memory, Intel Core i5 2.3GHz CPU, 64 bit Windows 7), this function will run into StackOverflow error for a linked list of size close to 10,000.
My point is that we should use recursion judiciously, always taking into account of the scale of the system. Often recursion can be converted to iterative program, which scales better. (One iterative version of the same algorithm is given at the bottom of the page, it reverses a singly linked list of size 1 million in 9 milliseconds.)
private static LinkedListNode doReverseRecursively(LinkedListNode x, LinkedListNode first){
LinkedListNode second = first.next;
first.next = x;
if(second != null){
return doReverseRecursively(first, second);
}else{
return first;
}
}
public static LinkedListNode reverseRecursively(LinkedListNode head){
return doReverseRecursively(null, head);
}
Iterative Version of the Same Algorithm:
public static LinkedListNode reverseIteratively(LinkedListNode head){
return doReverseIteratively(null, head);
}
private static LinkedListNode doReverseIteratively(LinkedListNode x, LinkedListNode first) {
while (first != null) {
LinkedListNode second = first.next;
first.next = x;
x = first;
if (second == null) {
break;
} else {
first = second;
}
}
return first;
}
public static LinkedListNode reverseIteratively(LinkedListNode head){
return doReverseIteratively(null, head);
}
See LINQ: How to get the latest/last record with a group by clause
var firstItemsInGroup = from b in mainButtons
group b by b.category into g
select g.First();
I assume that mainButtons are already sorted correctly.
If you need to specify custom sort order, use OrderBy override with Comparer.
var firstsByCompareInGroups = from p in rows
group p by p.ID into grp
select grp.OrderBy(a => a, new CompareRows()).First();
See an example in my post "Select First Row In Group using Custom Comparer"

Another thing I would like to add is that you need to select View -> Tool Windows -> Gradle before you can run the project using the Gradle.
If using the Gradle the project builds and runs normally but using the IntelliJ it doesn't, then this can solve the matter.

What behaviour do you expect when it's not a number?
If, for example, you often have a default value to use when the input is not a number, then a method such as this could be useful:
public static int parseWithDefault(String number, int defaultVal) {
try {
return Integer.parseInt(number);
} catch (NumberFormatException e) {
return defaultVal;
}
}
Similar methods can be written for different default behaviour when the input can't be parsed.
You could use SysInternal's PsExec.
When you use the input function it automatically turns it into a string. You need to go:
vote = int(input('Enter the name of the player you wish to vote for'))
which turns the input into a int type value
With Bootstrap >4.1 it's just a case of using the flexbox utility classes. Just have a flexbox container inside your column, and then give all the elements within it the "flex-fill" class. As with inline forms you'll need to set the margins/padding on the elements yourself.

margin: .25rem 0 !important;_x000D_

I had a similar problem, it was due to a StringBuilder.ToString();
In my view, the best way to do this is via an API so that you do not add a large and complex dependency into your app that runs unmanaged code, that needs to be frequently updated.
Here is a simple way to do this, which is free for 800 requests/month:
var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
var apiInstance = new CloudmersiveConvertApiClient.ConvertWebApi();
var input = new CloudmersiveConvertApiClient.HtmlToPdfRequest(); // HtmlToPdfRequest | HTML to PDF request parameters
input.Html = "<b>Hello, world!</b>";
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.convertWebHtmlToPdf(input, callback);
With the above approach you can also install the API on-premises or on your own infrastructure if you prefer.
Use two dimensional array instead. For instance, int values[][] = new int[2][5];
Arrays are faster, when you are not manipulating much.
Here's an answer for 2017 on, where you probably only care about distinguishing <=IE11 from >IE11 ("Edge"):
@supports not (old: ie) { /* code for not old IE here */ }
More demonstrative example:
body:before { content: 'old ie'; }
/**/@supports not (old: ie) {
body:before { content: 'not old ie'; }
/**/}
This works because IE11 doesn't actually even support @supports
, and all other relevant browser/version combinations do.

Sorting a multidimensionnal array in VBA
The code samples in that thread include:
Alain's optimised Quicksort is very shiny: I just did a basic split-and-recurse, but the code sample above has a 'gating' function that cuts down on redundant comparisons of duplicated values. On the other hand, I code for Excel, and there's a bit more in the way of defensive coding - be warned, you'll need it if your array contains the pernicious 'Empty()' variant, which will break your While... Wend comparison operators and trap your code in an infinite loop.
Note that quicksort algorthms - and any recursive algorithm - can fill the stack and crash Excel. If your array has fewer than 1024 members, I'd use a rudimentary BubbleSort.

I know there is an accepted answer for this question and many other answers also but I just wanted to add an another case which happened with me was Updating the django and django rest framework to the latest versions to make them work properly without any error.
So all you have to do is just uninstall both django and django rest framework using:
pip uninstall django
pip uninstall djangorestframework
and then install it again using:
pip install django
pip install djangorestframework
If you want to lookup/associate an object with a unique identifier without modifying the underlying object, you can use a WeakMap
:
// Note that object must be an object or array,
// NOT a primitive value like string, number, etc.
var objIdMap=new WeakMap, objectCount = 0;
function objectId(object){
if (!objIdMap.has(object)) objIdMap.set(object,++objectCount);
return objIdMap.get(object);
}
var o1={}, o2={}, o3={a:1}, o4={a:1};
console.log( objectId(o1) ) // 1
console.log( objectId(o2) ) // 2
console.log( objectId(o1) ) // 1
console.log( objectId(o3) ) // 3
console.log( objectId(o4) ) // 4
console.log( objectId(o3) ) // 3
Using a WeakMap
instead of Map
ensures that the objects can still be garbage-collected.
Depending on your Color Model, there are different methods to create a darker (shaded) or lighter (tinted) color:
RGB
:
To shade:
newR = currentR * (1 - shade_factor)
newG = currentG * (1 - shade_factor)
newB = currentB * (1 - shade_factor)
To tint:
newR = currentR + (255 - currentR) * tint_factor
newG = currentG + (255 - currentG) * tint_factor
newB = currentB + (255 - currentB) * tint_factor
More generally, the color resulting in layering a color RGB(currentR,currentG,currentB)
with a color RGBA(aR,aG,aB,alpha)
is:
newR = currentR + (aR - currentR) * alpha
newG = currentG + (aG - currentG) * alpha
newB = currentB + (aB - currentB) * alpha
where (aR,aG,aB) = black = (0,0,0)
for shading, and (aR,aG,aB) = white = (255,255,255)
for tinting
HSV
or HSB
:
Value
/ Brightness
or increase the Saturation
Saturation
or increase the Value
/ Brightness
HSL
:
Lightness
Lightness
There exists formulas to convert from one color model to another. As per your initial question, if you are in RGB
and want to use the HSV
model to shade for example, you can just convert to HSV
, do the shading and convert back to RGB
. Formula to convert are not trivial but can be found on the internet. Depending on your language, it might also be available as a core function :
RGB
has the advantage of being really simple to implement, but:
HSV
or HSB
is kind of complex because you need to play with two parameters to get what you want (Saturation

part)The verification of the certificate identity is performed against what the client requests.
When your client uses https://xxx.xxx.xxx.xxx/something
(where xxx.xxx.xxx.xxx
is an IP address), the certificate identity is checked against this IP address (in theory, only using an IP SAN extension).
If your certificate has no IP SAN, but DNS SANs (or if no DNS SAN, a Common Name in the Subject DN), you can get this to work by making your client use a URL with that host name instead (or a host name for which the cert would be valid, if there are multiple possible values). For example, if you cert has a name for www.example.com
, use https://www.example.com/something
.
Of course, you'll need that host name to resolve to that IP address.
In addition, if there are any DNS SANs, the CN in the Subject DN will be ignored, so use a name that matches one of the DNS SANs in this case.
This one Works for me with asp label control.

I wanted to use the credential manager for normal use, but I have scripts where I obviously do not want any prompts whatsoever from git.exe
. This is how I invoke Git from my scripts:
set GIT_TERMINAL_PROMPT=0
git -c core.askpass= -c credential.helper= <command> ...
This way, the script always sees the "correct" no-prompt setting without having to adapt any configuration.
(Git for Windows 2.13.3)
A variation I found that might also come in handy is to set:
set GCM_INTERACTIVE=never
# Or: git config --global credential.interactive never
set GIT_TERMINAL_PROMPT=0
git.exe -c core.askpass= -c credential.helper=manager <command> ...
But note that git.exe -c credential.interactive=never <command> ...
does not work (it seems that the -c
thing isn't routed through to Git Credential Manager for Windows or whatever).
That way, you can use the GCMfW, but it will never prompt you; it will just lookup the credentials, which can be very helpful in non-interactive environs.
check Robocopy:
ROBOCOPY \\server-source\c$\VMExports\ C:\VMExports\ /E /COPY:DAT
make sure you check what robocopy parameter you want. this is just an example.
type robocopy /?
in a comandline/powershell on your windows system.
My pseudocode example will be as follows:
JSONArray jsonArray = "[{id:\"1\", name:\"sql\"},{id:\"2\",name:\"android\"},{id:\"3\",name:\"mvc\"}]";
JSON newJson = new JSON();
for (each json in jsonArray) {
String id = json.get("id");
String name = json.get("name");
newJson.put(id, name);
}
return newJson;
Do you use SSMS?
If yes, goto the menu Tools >> Options >> Designers and uncheck “Prevent Saving changes that require table re-creation”
GIT_CURL_VERBOSE=1 git [clone|fetch]…
should tell you where the problem is. In my case it was due to cURL not supporting PEM certificates when built against NSS, due to that support not being mainline in NSS (#726116 #804215 #402712 and more).
You can set border
properties on a tr
element, but according to the CSS 2.1 specification, such properties have no effect in the separated borders model, which tends to be the default in browsers. Ref.: 17.6.1 The separated borders model. (The initial value of border-collapse
is separate
according to CSS 2.1, and some browsers also set it as default value for table
. The net effect anyway is that you get separated border on almost all browsers unless you explicitly specifi collapse
.)
Thus, you need to use collapsing borders. Example:
<style>
table { border-collapse: collapse; }
tr:nth-child(3) { border: solid thin; }
</style>
Using HTML:
<div class="horizontal_dotted_line"></div>
and in styles.css:
.horizontal_dotted_line{
border-bottom: 1px dotted [color];
width: [put your width here]px;
}
No need to use the JavaScript or jquery, CSS is enough:
.child{ display:none; }
.parent:hover .child{ display:block; }
It looks like your 'trainData' is a list of strings:
['-214' '-153' '-58' ..., '36' '191' '-37']
Change your 'trainData' to a numeric type.

Your first selector looks for elements with the attribute value, contained in elements with the class.
The space is being interpreted as the descendant selector.
Your second selector, like you said, looks for elements with either the attribute value, or the class, or both.
The comma is being interpreted as the multiple selector operator — whatever that means (CSS selectors don't have a notion of "operators"; the comma is probably more accurately known as a delimiter).
For me the following lines of code did the trick
mysqldump --quote-names -q -u username1 --password='password1' originalDB | mysql -u username2 --password='password2' duplicateDB
Just my couple cents... sometimes it's good to be sure there are no any duplicates... so we have the next function in the utils library:
jQuery.loadCSS = function(url) {
if (!$('link[href="' + url + '"]').length)
$('head').append('<link rel="stylesheet" type="text/css" href="' + url + '">');
}
How to use:
$.loadCSS('css/style2.css');
Unlike div
, p
1 which are Block Level elements which can take up margin
on all sides,span
2 cannot as it's an Inline element which takes up margins horizontally only.
From the specification:
Margin properties specify the width of the margin area of a box. The 'margin' shorthand property sets the margin for all four sides while the other margin properties only set their respective side. These properties apply to all elements, but vertical margins will not have any effect on non-replaced inline elements.
Demo 1 (Vertical margin
not applied as span
is an inline
element)
Solution? Make your span
element, display: inline-block;
or display: block;
.
Would suggest you to use display: inline-block;
as it will be inline
as well as block
. Making it block
only will result in your element to render on another line, as block
level elements take 100%
of horizontal space on the page, unless they are made inline-block
or they are floated
to left
or right
.

Call the parent method with the parent scope resolution operator.
Parent::method()
class Primate {
public:
void whatAmI(){
cout << "I am of Primate order";
}
};
class Human : public Primate{
public:
void whatAmI(){
cout << "I am of Human species";
}
void whatIsMyOrder(){
Primate::whatAmI(); // <-- SCOPE RESOLUTION OPERATOR
}
};
Like timber said - "Java 8 Collection has a nice method called removeIf that makes things easier and safer"
Here is the code that solve your problem:
set.removeIf((Integer element) -> {
return (element % 2 == 0);
});
Now your set contains only odd values.
While many people have pointed out that you can't execute dlls directly and should use rundll32.exe to execute exported functions instead, here is a screenshot of an actual dll file running just like an executable:
While you cannot run dll files directly, I suspect it is possible to run them from another process using a WinAPI function CreateProcess:

A solution with service
and awk
that takes in a comma-delimited list of service names.
First it's probably a good bet you'll need root privileges to do what you want. If you don't need to check then you can remove that part.
#!/usr/bin/env bash
# First parameter is a comma-delimited string of service names i.e. service1,service2,service3
SERVICES=$1
ALL_SERVICES_STARTED=true
if [ $EUID -ne 0 ]; then
if [ "$(id -u)" != "0" ]; then
echo "root privileges are required" 1>&2
exit 1
fi
exit 1
fi
for service in ${SERVICES//,/ }
do
STATUS=$(service ${service} status | awk '{print $2}')
if [ "${STATUS}" != "started" ]; then
echo "${service} not started"
ALL_SERVICES_STARTED=false
fi
done
if ${ALL_SERVICES_STARTED} ; then
echo "All services started"
exit 0
else
echo "Check Failed"
exit 1
fi
I recommend you to use JSON.NET
. it is an open source library to serialize and deserialize your c# objects into json and Json objects into .net objects ...
Serialization Example:
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };
string json = JsonConvert.SerializeObject(product);
//{
// "Name": "Apple",
// "Expiry": new Date(1230422400000),
// "Price": 3.99,
// "Sizes": [
// "Small",
// "Medium",
// "Large"
// ]
//}
Product deserializedProduct = JsonConvert.DeserializeObject<Product>(json);
Performance Comparison To Other JSON serializiation Techniques
There needs to be some type of backend framework to send the email. This can be done via PHP/ASP.NET, or with the local mail client. If you want the user to see nothing, the best way is to tap into those by an AJAX call to a separate send_email file.
I find this image very meaningful :
(from : Oliver Steele -My Git Workflow (2008) )
You need to ensure you are in a directory in which you have write permission. This might not be the directory in which Git is in once you open the terminal. In my case (Widows 10) I had to use the cd command to change the directory to the root directory (C:) After that it worked just fine.
If you're having this sort of problem with a while
loop, rather than a for
loop, for example:
var i = 0;
while (i < 5) {
setTimeout(function() {
console.log(i);
}, i * 1000);
i++;
}
_x000D_
The technique to close over the current value is a bit different. Declare a block-scoped variable with const
inside the while
block, and assign the current i
to it. Then, wherever the variable is being used asynchronously, replace i
with the new block-scoped variable:
var i = 0;
while (i < 5) {
const thisIterationI = i;
setTimeout(function() {
console.log(thisIterationI);
}, i * 1000);
i++;
}
_x000D_
For older browsers that don't support block-scoped variables, you can use an IIFE called with i
:
var i = 0;
while (i < 5) {
(function(innerI) {
setTimeout(function() {
console.log(innerI);
}, innerI * 1000);
})(i);
i++;
}
_x000D_
If the asynchronous action to be invoked happens to be setTimeout
like the above, you can also call setTimeout
with a third parameter to indicate the argument to call the passed function with:
var i = 0;
while (i < 5) {
setTimeout(
(thisIterationI) => { // Callback
console.log(thisIterationI);
},
i * 1000, // Delay
i // Gets passed to the callback; becomes thisIterationI
);
i++;
}
_x000D_
Pandas (and numpy) allow for boolean indexing, which will be much more efficient:
In [11]: df.loc[df['col1'] >= 1, 'col1']
Out[11]:
1 1
2 2
Name: col1
In [12]: df[df['col1'] >= 1]
Out[12]:
col1 col2
1 1 11
2 2 12
In [13]: df[(df['col1'] >= 1) & (df['col1'] <=1 )]
Out[13]:
col1 col2
1 1 11
If you want to write helper functions for this, consider something along these lines:
In [14]: def b(x, col, op, n):
return op(x[col],n)
In [15]: def f(x, *b):
return x[(np.logical_and(*b))]
In [16]: b1 = b(df, 'col1', ge, 1)
In [17]: b2 = b(df, 'col1', le, 1)
In [18]: f(df, b1, b2)
Out[18]:
col1 col2
1 1 11
Update: pandas 0.13 has a query method for these kind of use cases, assuming column names are valid identifiers the following works (and can be more efficient for large frames as it uses numexpr behind the scenes):
In [21]: df.query('col1 <= 1 & 1 <= col1')
Out[21]:
col1 col2
1 1 11
This warning comes because your dataframe x
is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.
You can either create a proper dataframe
out of x by doing
x = x.copy()
This will remove the warning, but it is not the proper way
You should be using the DataFrame.loc
method, as the warning suggests, like this:
x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)

Its an XML namespace. It is required when you use XHTML 1.0 or 1.1 doctypes or application/xhtml+xml mimetypes.
You should be using HTML5 doctype, then you don't need it for text/html. Better start from template like this :
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>domcument title</title>
<link rel="stylesheet" href="/stylesheet.css" type="text/css" />
</head>
<body>
<!-- your html content -->
<script src="/script.js"></script>
</body>
</html>
When you have put your Doctype straight - do and validate you html and your css .
That usually will sove you layout issues.
Just use the -H
parameter several times:
curl -H "Accept-Charset: utf-8" -H "Content-Type: application/x-www-form-urlencoded" http://www.some-domain.com
Check out the recently1 released upload handler from the guys that created the TinyMCE editor. It has a jQuery widget and looks like it has a nice set of features and fallbacks.
The error SQLSTATE[HY000] [1040] Too many connections
is an SQL error, and has to do with the sql server. There could be other applications connecting to the server. The server has a maximum available connections number.
If you have phpmyadmin, you can use the 'variables' tab to check what the setting is.
You can also query the status table like so:
show status like '%onn%';
Or some variance on that. check the manual for what variables there are
(be aware, 'connections' is not the current connections, check that link :) )
You always set x
to 0
before changing array's value.
You can use:
int[] tall = new int[28123];
for (int j = 0;j<28123;j++){
// Or whatever value you want to set.
tall[j] = j + 1;
}
Or just remove the initialization of x (int x=0
) before the for loop.
No. I create labels above the listbox to serve as headers. You might think that it's a royal pain to change labels every time your lisbox changes. You'd be right - it is a pain. It's a pain to set up the first time, much less changes. But I haven't found a better way.
