I know this thread is old, but still answering it so that no-one else should spend sleepless nights.
I was refactoring an old project, whose layout files all contained hardcoded
attributes such as android:maxLength = 500. So I decided to register it in my
res/dimen file as <dimen name="max_length">500</dimen>.
Finished refactoring almost 30 layout files with my res-value. Guess what? the next time I ran my project it started throwing the same InflateException.
As a solution, needed to redo my all changes and keep all-those values as same as before.
TLDR;
step 1: All running good.
step 2: To boost my maintenance I replaced android:maxLength = 500 with <dimen name="max_length">500</dimen> and android:maxLength = @dimen/max_length , that's where it all went wrong(crashing with InflateException).
step 3: All running bad
step 4: Re-do all my work by again replacing android:maxLength = @dimen/max_length with android:maxLength = 500.Everything got fixed.
step 5: All running good.
LayoutInflator do?When I first started Android programming, I was really confused by LayoutInflater and findViewById. Sometimes we used one and sometimes the other.
LayoutInflater is used to create a new View (or Layout) object from one of your xml layouts.findViewById just gives you a reference to a view than has already been created. You might think that you haven't created any views yet, but whenever you call setContentView in onCreate, the activity's layout along with its subviews gets inflated (created) behind the scenes.So if the view already exists, then use findViewById. If not, then create it with a LayoutInflater.
Here is a mini project I made that shows both LayoutInflater and findViewById in action. With no special code, the layout looks like this.
The blue square is a custom layout inserted into the main layout with include (see here for more). It was inflated automatically because it is part of the content view. As you can see, there is nothing special about the code.
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Now let's inflate (create) another copy of our custom layout and add it in.
LayoutInflater inflater = getLayoutInflater();
View myLayout = inflater.inflate(R.layout.my_layout, mainLayout, false);
To inflate the new view layout, all I did was tell the inflater the name of my xml file (my_layout), the parent layout that I want to add it to (mainLayout), and that I don't actually want to add it yet (false). (I could also set the parent to null, but then the layout parameters of my custom layout's root view would be ignored.)
Here it is again in context.
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// inflate the main layout for the activity
setContentView(R.layout.activity_main);
// get a reference to the already created main layout
LinearLayout mainLayout = (LinearLayout) findViewById(R.id.activity_main_layout);
// inflate (create) another copy of our custom layout
LayoutInflater inflater = getLayoutInflater();
View myLayout = inflater.inflate(R.layout.my_layout, mainLayout, false);
// make changes to our custom layout and its subviews
myLayout.setBackgroundColor(ContextCompat.getColor(this, R.color.colorAccent));
TextView textView = (TextView) myLayout.findViewById(R.id.textView);
textView.setText("New Layout");
// add our custom layout to the main layout
mainLayout.addView(myLayout);
}
}
Notice how findViewById is used only after a layout has already been inflated.
Here is the xml for the example above.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/activity_main_layout"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp">
<!-- Here is the inserted layout -->
<include layout="@layout/my_layout"/>
</LinearLayout>
my_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="100dp"
android:layout_height="100dp"
android:background="@color/colorPrimary">
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:padding="5dp"
android:textColor="@android:color/white"
android:text="My Layout"/>
</RelativeLayout>
RecyclerView. (See these RecyclerView examples for a list or a grid.) You have to inflate a new layout for every single visible item in the list or grid."Inflating" a view means taking the layout XML and parsing it to create the view and viewgroup objects from the elements and their attributes specified within, and then adding the hierarchy of those views and viewgroups to the parent ViewGroup. When you call setContentView(), it attaches the views it creates from reading the XML to the activity. You can also use LayoutInflater to add views to another ViewGroup, which can be a useful tool in a lot of circumstances.
You inflate an XML resource. See the LayoutInflater doc .
If your layout is in a mylayout.xml, you would do something like:
View view;
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.mylayout, null);
RelativeLayout item = (RelativeLayout) view.findViewById(R.id.item);
Update April 2018
You can do this in the search section of vscode by pre-fixing an exclamation mark to each folder or file you want to exclude.
You can use Angular-Validator.
Example: using a function to validate a field
<input type = "text"
name = "firstName"
ng-model = "person.firstName"
validator = "myCustomValidationFunction(form.firstName)">
Then in your controller you would have something like
$scope.myCustomValidationFunction = function(firstName){
if ( firstName === "John") {
return true;
}
You can also do something like this:
<input type = "text"
name = "firstName"
ng-model = "person.firstName"
validator = "'!(field1 && field2 && field3)'"
invalid-message = "'This field is required'">
(where field1 field2, and field3 are scope variables. You might also want to check if the fields do not equal the empty string)
If the field does not pass the validator then the field will be marked as invalid and the user will not be able to submit the form.
For more use cases and examples see: https://github.com/turinggroup/angular-validator

Google removed the need to ask permission for the internet for the latest version. Still, to request for internet permission in your code you must add these to your AndroidManifest.xml file.
<uses-permission android:name="android.permission.INTERNET"/>
For example, say you were creating a web application to list and display recipes. You might want your customers to be able to sort the list, display features of the recipes, and so on before they choose the recipe to open. In order to do this, you need to associate things like cooking time, primary ingredient, meal position, and so on right inside the list elements for the recipes.
<li><a href="recipe1.html">Borscht</a></li>
<li><a href="recipe2.html">Chocolate Mousse</a></li>
<li><a href="recipe3.html">Almond Radiccio Salad</a></li>
<li><a href="recipe4.html">Deviled Eggs</a></li>
In order to get that information into the page, you could do many different things. You could add comments to each LI element, you could add rel attributes to the list items, you could place all the recipes in separate folders based on time, meal, and ingredient (i.e. ). The solution that most developers took was to use class attributes to store information about the current element. This has several advantages:
But there are some major drawbacks to this method:
All the other methods I suggested had these problems as well as others. But since it was the only way to quickly and easily include data, that’s what we did. HTML5 Data Attributes to the Rescue
HTML5 added a new type of attribute to any element—the custom data element (data-*). These are custom (denoted by the *) attributes that you can add to your HTML elements to define any type of data you want. They consist of two parts:
Attribute Name This is the name of the attribute. It must be at least one lowercase character and have the prefix data-. For example: data-main-ingredient, data-cooking-time, data-meal. This is the name of your data.
Attribute Vaule Like any other HTML attribute, you include the data itself in quotes separated by an equal sign. This data can be any string that is valid on a web page. For example: data-main-ingredient="chocolate".
You can then apply these data attributes to any HTML element you want. For example, you could define the information in the example list above:
<li data-main-ingredient="beets" data-cooking-time="1 hour" data-meal="dinner"><a href="recipe1.html">Borscht</a></li>
<li data-main-ingredient="chocolate" data-cooking-time="30 minutes" data-meal="dessert"><a href="recipe2.html">Chocolate Mousse</a></li>
<li data-main-ingredient="radiccio" data-cooking-time="20 minutes" data-meal="dinner"><a href="recipe1.html">Almond Radiccio Salad</a></li>
<li data-main-ingredient="eggs" data-cooking-time="15 minutes" data-meal="appetizer"><a href="recipe1.html">Deviled Eggs</a></li>
Once you have that information in your HTML, you will be able to access it with JavaScript and manipulate the page based on that data.
value = value.setScale(2, RoundingMode.CEILING)
node-http-proxy is a great solution as was suggested by @hross above. If you're not deadset on using node, we use NGINX to do the same thing. It works really well with node. We use it for example to process SSL requests before forwarding them to node. It can also handle cacheing and forwarding routes. Yay!
If, like me, you find you want essentially the same sorting code in more than one place, or just want to keep the code complexity down, you can abstract away the sorting itself to a separate function, to which you pass the function that does the actual work you want (which would be different at each call site, of course).
Given a map with key type K and value type V, represented as <K> and <V> below, the common sort function might look something like this Go-code template (which Go version 1 does not support as-is):
/* Go apparently doesn't support/allow 'interface{}' as the value (or
/* key) of a map such that any arbitrary type can be substituted at
/* run time, so several of these nearly-identical functions might be
/* needed for different key/value type combinations. */
func sortedMap<K><T>(m map[<K>]<V>, f func(k <K>, v <V>)) {
var keys []<K>
for k, _ := range m {
keys = append(keys, k)
}
sort.Strings(keys) # or sort.Ints(keys), sort.Sort(...), etc., per <K>
for _, k := range keys {
v := m[k]
f(k, v)
}
}
Then call it with the input map and a function (taking (k <K>, v <V>) as its input arguments) that is called over the map elements in sorted-key order.
So, a version of the code in the answer posted by Mingu might look like:
package main
import (
"fmt"
"sort"
)
func sortedMapIntString(m map[int]string, f func(k int, v string)) {
var keys []int
for k, _ := range m {
keys = append(keys, k)
}
sort.Ints(keys)
for _, k := range keys {
f(k, m[k])
}
}
func main() {
// Create a map for processing
m := make(map[int]string)
m[1] = "a"
m[2] = "c"
m[0] = "b"
sortedMapIntString(m,
func(k int, v string) { fmt.Println("Key:", k, "Value:", v) })
}
The sortedMapIntString() function can be re-used for any map[int]string (assuming the same sort order is desired), keeping each use to just two lines of code.
Downsides include:
Other languages have various solutions:
<K> and <V> (to denote types for the key and value) looks a bit familiar, that code template is not terribly unlike C++ templates.range a first-class type such that it could be substituted with a custom ordered-range (in place of range in the original code), I think some other languages provide iterators that are powerful enough to accomplish the same thing.Any Python file is a module, its name being the file's base name without the .py extension. A package is a collection of Python modules: while a module is a single Python file, a package is a directory of Python modules containing an additional __init__.py file, to distinguish a package from a directory that just happens to contain a bunch of Python scripts. Packages can be nested to any depth, provided that the corresponding directories contain their own __init__.py file.
The distinction between module and package seems to hold just at the file system level. When you import a module or a package, the corresponding object created by Python is always of type module. Note, however, when you import a package, only variables/functions/classes in the __init__.py file of that package are directly visible, not sub-packages or modules. As an example, consider the xml package in the Python standard library: its xml directory contains an __init__.py file and four sub-directories; the sub-directory etree contains an __init__.py file and, among others, an ElementTree.py file. See what happens when you try to interactively import package/modules:
>>> import xml
>>> type(xml)
<type 'module'>
>>> xml.etree.ElementTree
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'etree'
>>> import xml.etree
>>> type(xml.etree)
<type 'module'>
>>> xml.etree.ElementTree
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'ElementTree'
>>> import xml.etree.ElementTree
>>> type(xml.etree.ElementTree)
<type 'module'>
>>> xml.etree.ElementTree.parse
<function parse at 0x00B135B0>
In Python there also are built-in modules, such as sys, that are written in C, but I don't think you meant to consider those in your question.

Remove your key listener or return true when you have KEY_BACK.
You just need the following to catch the back key (Make sure not to call super in onBackPressed()).
Also, if you plan on having a service run in the background, make sure to look at startForeground() and make sure to have an ongoing notification or else Android will kill your service if it needs to free memory.

This kind of operation is covered under hierarchical indexing. Check out the examples here
When you groupby, you're making new indices. If you also pass a list through .agg(). you'll get multiple columns. I was trying to figure this out and found this thread via google.
It turns out if you pass a tuple corresponding to the exact column you want sorted on.
Try this:
# generate toy data
ex = pd.DataFrame(np.random.randint(1,10,size=(100,3)), columns=['features', 'AUC', 'recall'])
# pass a tuple corresponding to which specific col you want sorted. In this case, 'mean' or 'AUC' alone are not unique.
ex.groupby('features').agg(['mean','std']).sort_values(('AUC', 'mean'))
This will output a df sorted by the AUC-mean column only.

The problem is because your file are not with the same encoding. First run the following command in all your files:
file -i filename.*
In order to fix the problem you have to change all your files to uft-8. You can do it with the command iconv:
iconv -f fromcode -t tocode filename > newfilename
Example:
iconv -f iso-8859-1 -t utf-8 index.html > fixed/index.html
After this you can run file -i fixedx/index.html and you will see that your file is now in uft-8
df <- data.frame(x=rnorm(10), y=rnorm(10))
rownames(df) <- letters[1:10]
df[c('a','b'),]
AStyle can be customized in great detail for C++ and Java (and others too)
This is a source code formatting tool.
clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.
It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).
It can be configured with a variety of options listed here.
When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.
Styles can be inherited from a preset (say LLVM or Google) and can later override different options
It is used by Google and others and is production ready.
Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.
Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.
Just to add another approach here, the "ticks approach" that WCF takes is prone to problems with timezones if you're not extremely careful such as described here and in other places. So I'm now using the ISO 8601 format that both .NET & JavaScript duly support that includes timezone offsets. Below are the details:
In WCF/.NET:
Where CreationDate is a System.DateTime; ToString("o") is using .NET's Round-trip format specifier that generates an ISO 8601-compliant date string
new MyInfo {
CreationDate = r.CreationDate.ToString("o"),
};
In JavaScript
Just after retrieving the JSON I go fixup the dates to be JavaSript Date objects using the Date constructor which accepts an ISO 8601 date string...
$.getJSON(
"MyRestService.svc/myinfo",
function (data) {
$.each(data.myinfos, function (r) {
this.CreatedOn = new Date(this.CreationDate);
});
// Now each myinfo object in the myinfos collection has a CreatedOn field that is a real JavaScript date (with timezone intact).
alert(data.myinfos[0].CreationDate.toLocaleString());
}
)
Once you have a JavaScript date you can use all the convenient and reliable Date methods like toDateString, toLocaleString, etc.
I use this regex in Java ^(0[1-9]|1[012])[/](0[1-9]|[12][0-9]|3[01])[/](19|[2-9][0-9])[0-9]{2}$

You can create a Blob from your base64 data, and then read it asDataURL:
var img_b64 = canvas.toDataURL('image/png');
var png = img_b64.split(',')[1];
var the_file = new Blob([window.atob(png)], {type: 'image/png', encoding: 'utf-8'});
var fr = new FileReader();
fr.onload = function ( oFREvent ) {
var v = oFREvent.target.result.split(',')[1]; // encoding is messed up here, so we fix it
v = atob(v);
var good_b64 = btoa(decodeURIComponent(escape(v)));
document.getElementById("uploadPreview").src = "data:image/png;base64," + good_b64;
};
fr.readAsDataURL(the_file);
Full example (includes junk code and console log): http://jsfiddle.net/tTYb8/
Alternatively, you can use .readAsText, it works fine, and its more elegant.. but for some reason text does not sound right ;)
fr.onload = function ( oFREvent ) {
document.getElementById("uploadPreview").src = "data:image/png;base64,"
+ btoa(oFREvent.target.result);
};
fr.readAsText(the_file, "utf-8"); // its important to specify encoding here
Full example: http://jsfiddle.net/tTYb8/3/
I think everyone missed the "suddenly" part of this question. Most likely, your .jshintrc has a syntax error, so it's not including the 'browser' line. Run it through a json validator to see where the error is.
You can use the following code to hide a table column..
JQuery("tableName").hideCol("colName");
And you can use the following code to show it again.
JQuery("tableName").showCol("colName");
For your question, you can call the hideCol() code on the document.ready(), and you can bind the showCol() code on the dialog's edit/click event.

Based on the stacktrace, an intuit class com.intuit.ipp.aggcat.util.SAML2AssertionGenerator needs a saml jar on the classpath.
A saml class org.opensaml.xml.XMLConfigurator needs on it's turn log4j, which is inside the WAR but cannot find it.
One explanation for this is that the class XMLConfigurator that needs log4j was found not inside the WAR but on a downstream classloader. could a saml jar be missing from the WAR?
The class XMLConfigurator that needs log4j cannot find it at the level of the classloader that loaded it, and the log4j version on the WAR is not visible on that particular classloader.
In order to troubleshoot this, a way is to add this before the oauth call:
System.out.println("all versions of log4j Logger: " + getClass().getClassLoader().getResources("org/apache/log4j/Logger.class") );
System.out.println("all versions of XMLConfigurator: " + getClass().getClassLoader().getResources("org/opensaml/xml/XMLConfigurator.class") );
System.out.println("all versions of XMLConfigurator visible from the classloader of the OAuthAuthorizer class: " + OAuthAuthorizer.class.getClassLoader().getResources("org/opensaml/xml/XMLConfigurator.class") );
System.out.println("all versions of log4j visible from the classloader of the OAuthAuthorizer class: " + OAuthAuthorizer.class.getClassloader().getResources("org/apache/log4j/Logger.class") );
Also if you are using Java 7, have a look at jHades, it's a tool I made to help troubleshooting these type of problems.
In order to see what is going on, could you post the results of the classpath queries above, for which container is this happening, tomcat, jetty? It would be better to put the full stacktrace with all the caused by's in pastebin, just in case.
Another solution would be as below where the list is placed under a drop-down button.

To change the time in the database use: http://laravel.com/docs/4.2/eloquent#timestamps
Providing A Custom Timestamp Format
If you wish to customize the format of your timestamps, you may override the getDateFormat method in your model:
class User extends Eloquent {
protected function getDateFormat()
{
return 'U';
}
}
https://laravel.com/docs/5.1/eloquent
If you need to customize the format of your timestamps, set the $dateFormat property on your model. This property determines how date attributes are stored in the database, as well as their format when the model is serialized to an array or JSON:
class Flight extends Model
{
/**
* The storage format of the model's date columns.
*
* @var string
*/
protected $dateFormat = 'U';
}
I was able to resolve this problem by cleaning my assets cache:

For Bash 3, there is a particular case that has a nice and simple solution:
If you don't want to handle a lot of variables, or keys are simply invalid variable identifiers, and your array is guaranteed to have less than 256 items, you can abuse function return values. This solution does not require any subshell as the value is readily available as a variable, nor any iteration so that performance screams. Also it's very readable, almost like the Bash 4 version.
Here's the most basic version:
hash_index() {
case $1 in
'foo') return 0;;
'bar') return 1;;
'baz') return 2;;
esac
}
hash_vals=("foo_val"
"bar_val"
"baz_val");
hash_index "foo"
echo ${hash_vals[$?]}
Remember, use single quotes in case, else it's subject to globbing. Really useful for static/frozen hashes from the start, but one could write an index generator from a hash_keys=() array.
Watch out, it defaults to the first one, so you may want to set aside zeroth element:
hash_index() {
case $1 in
'foo') return 1;;
'bar') return 2;;
'baz') return 3;;
esac
}
hash_vals=("", # sort of like returning null/nil for a non existent key
"foo_val"
"bar_val"
"baz_val");
hash_index "foo" || echo ${hash_vals[$?]} # It can't get more readable than this
Caveat: the length is now incorrect.
Alternatively, if you want to keep zero-based indexing, you can reserve another index value and guard against a non-existent key, but it's less readable:
hash_index() {
case $1 in
'foo') return 0;;
'bar') return 1;;
'baz') return 2;;
*) return 255;;
esac
}
hash_vals=("foo_val"
"bar_val"
"baz_val");
hash_index "foo"
[[ $? -ne 255 ]] && echo ${hash_vals[$?]}
Or, to keep the length correct, offset index by one:
hash_index() {
case $1 in
'foo') return 1;;
'bar') return 2;;
'baz') return 3;;
esac
}
hash_vals=("foo_val"
"bar_val"
"baz_val");
hash_index "foo" || echo ${hash_vals[$(($? - 1))]}
Add your variables in $GLOBALS super global array like
$GLOBALS['variable'] = 'localhost';
and use it globally
or you can use constant which are accessible throughout the script
define('HOSTNAME', 'localhost');
You must sort your data according your needs (es. in reverse order) and use select top query
Here's an example which helps to understand this:
public class Main {
static abstract class A {
abstract void foo();
A() {
System.out.println("Constructing A");
foo();
}
}
static class C extends A {
C() {
System.out.println("Constructing C");
}
void foo() {
System.out.println("Using C");
}
}
public static void main(String[] args) {
C c = new C();
}
}
If you run this code, you get the following output:
Constructing A
Using C
Constructing C
You see? foo() makes use of C before C's constructor has been run. If foo() requires C to have a defined state (i.e. the constructor has finished), then it will encounter an undefined state in C and things might break. And since you can't know in A what the overwritten foo() expects, you get a warning.
If the change is not too old, you can do,
git reflog
and then checkout the commit id
Those seem overly complex
def round_down_to():
num = int(datetime.utcnow().replace(second=0, microsecond=0).minute)
return num - (num%10)
I faced the same issue but, in my case, I had only to point my project to a JDK instead of the JRE in the build path then it solved the issue and I was able to import all maven dependencies with no problem!
std::sort(object.begin(), object.end(), pred());
where, pred() is a function object defining the order on objects of myclass. Alternatively, you can define myclass::operator<.
For example, you can pass a lambda:
std::sort(object.begin(), object.end(),
[] (myclass const& a, myclass const& b) { return a.v < b.v; });
Or if you're stuck with C++03, the function object approach (v is the member on which you want to sort):
struct pred {
bool operator()(myclass const & a, myclass const & b) const {
return a.v < b.v;
}
};
K = 32.44
FSPL = Ptx - CLtx + AGtx + AGrx - CLrx - Prx - FM
d = 10 ^ (( FSPL - K - 20 log10( f )) / 20 )
Here:
K - constant (32.44, when f in MHz and d in km, change to -27.55 when f in MHz and d in m)FSPL - Free Space Path LossPtx - transmitter power, dBm ( up to 20 dBm (100mW) )CLtx, CLrx - cable loss at transmitter and receiver, dB ( 0, if no cables )AGtx, AGrx - antenna gain at transmitter and receiver, dBiPrx - receiver sensitivity, dBm ( down to -100 dBm (0.1pW) )FM - fade margin, dB ( more than 14 dB (normal) or more than 22 dB (good))f - signal frequency, MHzd - distance, m or km (depends on value of K)Note: there is an error in formulas from TP-Link support site (mising ^).
Substitute Prx with received signal strength to get a distance from WiFi AP.
Example: Ptx = 16 dBm, AGtx = 2 dBi, AGrx = 0, Prx = -51 dBm (received signal strength), CLtx = 0, CLrx = 0, f = 2442 MHz (7'th 802.11bgn channel), FM = 22. Result: FSPL = 47 dB, d = 2.1865 m
Note: FM (fade margin) seems to be irrelevant here, but I'm leaving it because of the original formula.
You should take into acount walls, table http://www.liveport.com/wifi-signal-attenuation may help.
Example: (previous data) + one wooden wall ( 5 dB, from the table ). Result: FSPL = FSPL - 5 dB = 44 dB, d = 1.548 m
Also please note, that antena gain dosn't add power - it describes the shape of radiation pattern (donut in case of omnidirectional antena, zeppelin in case of directional antenna, etc).
None of this takes into account signal reflections (don't have an idea how to do this). Probably noise is also missing. So this math may be good only for rough distance estimation.
Although it doesn't precisely answer the question, I landed here when searching for a way to get the collection of elements (potentially different tag names) that simply had a given attribute name (without filtering by attribute value). I found that the following worked well for me:
$("*[attr-name]")
Hope that helps somebody who happens to land on this page looking for the same thing that I was :).
Update: It appears that the asterisk is not required, i.e. based on some basic tests, the following seems to be equivalent to the above (thanks to Matt for pointing this out):
$("[attr-name]")
Comments on EntryPoint function in code
// ENTRYPOINT /usr/sbin/nginx.
// Set the entrypoint (which defaults to sh -c) to /usr/sbin/nginx.
// Will accept the CMD as the arguments to /usr/sbin/nginx.
Another reference from documents
You can use the exec form of ENTRYPOINT to set fairly stable default commands and arguments and then use CMD to set additional defaults that are more likely to be changed.
Example:
FROM ubuntu:14.04.3
ENTRYPOINT ["/bin/ping"]
CMD ["localhost", "-c", "2"]
Build: sudo docker build -t ent_cmd .
CMD arguments are easy to override.
NO argument (sudo docker -it ent_cmd) : ping localhost
argument (sudo docker run -it ent_cmd google.com) : ping google.com
.
To override EntryPoint argument, you need to supply entrypoint
sudo docker run -it --entrypoint="/bin/bash" ent_cmdd
p.s: In presence of EntryPoint, CMD will hold arguments to fed to EntryPoint. In absense of EntryPoint, CMD will be the command which will be run.
For retrieving the screen resolution, you're going to want to use the System.Windows.Forms.Screen class. The Screen.AllScreens property can be used to access a collection of all of the displays on the system, or you can use the Screen.PrimaryScreen property to access the primary display.
The Screen class has a property called Bounds, which you can use to determine the resolution of the current instance of the class. For example, to determine the resolution of the current screen:
Rectangle resolution = Screen.PrimaryScreen.Bounds;
For changing the resolution, things get a little more complicated. This article (or this one) provides a detailed implementation and explanation. Hope this helps.
Just passing the file object to the putobject method worked for me. If you are getting a stream, try writing it to a temp file before passing it on to S3.
amazonS3.putObject(bucketName, id,fileObject);
I am using Aws SDK v1.11.414
The answer at https://stackoverflow.com/a/35904801/2373449 helped me
Or by direct string access:
$string[strlen($string)-1];
Note that this doesn't work for multibyte strings. If you need to work with multibyte string, consider using the mb_* string family of functions.
As of PHP 7.1.0 negative numeric indices are also supported, e.g just $string[-1];
If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.
I would recommend looking at the numpy broadcasting rules.
You can try the following. Works fine in my case:
Hope that helps.
Solution1 - set global config, by running this command:
git config --system core.longpaths true
Solution2 - or you can edit directly your specific git config file like below:
YourRepoFolder -> .git -> config:
[core]
repositoryformatversion = 0
filemode = false
...
longpaths = true <-- (add this line under core section)
Solution3 - when cloning a new repository: here.
Great sadness: neither Cloneable/clone nor a constructor are great solutions: I DON'T WANT TO KNOW THE IMPLEMENTING CLASS!!! (e.g. - I have a Map, which I want copied, using the same hidden MumbleMap implementation) I just want to make a copy, if doing so is supported. But, alas, Cloneable doesn't have the clone method on it, so there is nothing to which you can safely type-cast on which to invoke clone().
Whatever the best "copy object" library out there is, Oracle should make it a standard component of the next Java release (unless it already is, hidden somewhere).
Of course, if more of the library (e.g. - Collections) were immutable, this "copy" task would just go away. But then we would start designing Java programs with things like "class invariants" rather than the verdammt "bean" pattern (make a broken object and mutate until good [enough]).
If you're looking for short answer:
In the case of using java.util.Date, Java doesn't really know how to directly relate to SQL types. This is when @Temporal comes into play. It's used to specify the desired SQL type.

Without giving the database name the table is can't be renamed in my case, I followed the below command to rename the table.
RENAME TABLE current_db.tbl_name TO current_db.tbl_name;
Use Thread.sleep(long millis).
Causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds, subject to the precision and accuracy of system timers and schedulers. The thread does not lose ownership of any monitors.
One minute would be (60*1000) = 60000 milliseconds.
For example, this loop will print the current time once every 5 seconds:
try {
while (true) {
System.out.println(new Date());
Thread.sleep(5 * 1000);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
If your sleep period becomes too large for int, explicitly compute in long (e.g. 1000L).
If both your client and service is installed on the same machine, and you are facing this problem with the correct (read: tried and tested elsewhere) client and service configurations, then this might be worth checking.
Check host entries in your host file
%windir%/system32/drivers/etc/hosts
Check to see if you are accessing your web service with a hostname, and that same hostname has been associated with an IP address in the hosts file mentioned above. If yes, NTLM/Windows credentials will NOT be passed from the client to the service as any request for that hostname will be routed again at the machine level.
Try either of the following
Edit: Somehow the above situation is relevant on a load-balanced scenario. However, if removing the host entries is not possible, then disabling loop back check on the machine will help. Refer method 2 in the article https://support.microsoft.com/en-us/kb/896861
int i = 100;// explicitly typed
var j = 100; // implicitly typed
Finally the wait is over in SQL Server 2016 they have introduced Split string function : STRING_SPLIT
select * From STRING_SPLIT ('a,b', ',') cs
All the other methods to split string like XML, Tally table, while loop, etc.. has been blown away by this STRING_SPLIT function.
Here is an excellent article with performance comparison : Performance Surprises and Assumptions : STRING_SPLIT
To understand Strong and Weak reference consider below example, suppose we have method named as displayLocalVariable.
-(void)displayLocalVariable
{
UIView* myView = [[UIView alloc] init];
NSLog(@"myView tag is = %ld", myView.tag);
}
In above method scope of myView variable is limited to displayLocalVariable method, once the method gets finished myView variable which is holding the UIView object will get deallocated from the memory.
Now what if we want to hold the myView variable throughout our view controller's life cycle. For this we can create the property named as usernameView which will have Strong reference to the variable myView(see @property(nonatomic,strong) UIView* usernameView; and self.usernameView = myView; in below code), as below,
@interface LoginViewController ()
@property(nonatomic,strong) UIView* usernameView;
@property(nonatomic,weak) UIView* dummyNameView;
- (void)displayLocalVariable;
@end
@implementation LoginViewController
- (void)viewDidLoad
{
[super viewDidLoad];
}
-(void)viewWillAppear:(BOOL)animated
{
[self displayLocalVariable];
}
- (void)displayLocalVariable
{
UIView* myView = [[UIView alloc] init];
NSLog(@"myView tag is = %ld", myView.tag);
self.usernameView = myView;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
@end
Now in above code you can see myView has been assigned to self.usernameView and self.usernameView is having a strong reference(as we declared in interface using @property) to myView. Hence myView will not get deallocated from memory till self.usernameView is alive.
Now consider assigning myName to dummyNameView which is a Weak reference, self.dummyNameView = myView; Unlike Strong reference Weak will hold the myView only till there is Strong reference to myView. See below code to understand Weak reference,
-(void)displayLocalVariable
{
UIView* myView = [[UIView alloc] init];
NSLog(@"myView tag is = %ld", myView.tag);
self.dummyNameView = myView;
}
In above code there is Weak reference to myView(i.e. self.dummyNameView is having Weak reference to myView) but there is no Strong reference to myView, hence self.dummyNameView will not be able to hold the myView value.
Now again consider the below code,
-(void)displayLocalVariable
{
UIView* myView = [[UIView alloc] init];
NSLog(@"myView tag is = %ld", myView.tag);
self.usernameView = myView;
self.dummyNameView = myView;
}
In above code self.usernameView has a Strong reference to myView, hence self.dummyNameView will now have a value of myView even after method ends since myView has a Strong reference associated with it.
Now whenever we make a Strong reference to a variable it's retain count get increased by one and the variable will not get deallocated till it's retain count reaches to 0.
Hope this helps.
Use compareTo() function that's built into the class.
First of all, be careful! All of your security depends on the… er… privacy of your private keys. Keytool doesn't have key export built in to avoid accidental disclosure of this sensitive material, so you might want to consider some extra safeguards that could be put in place to protect your exported keys.
Here is some simple code that gives you unencrypted PKCS #8 PrivateKeyInfo that can be used by OpenSSL (see the -nocrypt option of its pkcs8 utility):
KeyStore keys = ...
char[] password = ...
Enumeration<String> aliases = keys.aliases();
while (aliases.hasMoreElements()) {
String alias = aliases.nextElement();
if (!keys.isKeyEntry(alias))
continue;
Key key = keys.getKey(alias, password);
if ((key instanceof PrivateKey) && "PKCS#8".equals(key.getFormat())) {
/* Most PrivateKeys use this format, but check for safety. */
try (FileOutputStream os = new FileOutputStream(alias + ".key")) {
os.write(key.getEncoded());
os.flush();
}
}
}
If you need other formats, you can use a KeyFactory to get a transparent key specification for different types of keys. Then you can get, for example, the private exponent of an RSA private key and output it in your desired format. That would make a good topic for a follow-up question.
First, open your application module build.gradle file.
Check the classpath according to your project dependency. If not change the version of this classpath.
from:
classpath 'com.android.tools.build:gradle:1.0.0'
To:
classpath 'com.android.tools.build:gradle:2.3.2'
or higher version according to your gradle of android studio.
If its still problem, then change buildToolsVersion:
From:
buildToolsVersion '21.0.0'
To:
buildToolsVersion '25.0.0'
then hit 'Try again' and gradle will automatically sync. This will solve it.
Try this code...
ScriptManager.RegisterClientScriptBlock(UpdatePanel1, this.GetType(), "script", "alert('Hi');", true);
Where UpdatePanel1 is the id for Updatepanel on your page
Starting from Java 7:
Define a path and the String containing the line separator at the beginning:
Path p = Paths.get("C:\\Users\\first.last\\test.txt");
String s = System.lineSeparator() + "New Line!";
and then you can use one of the following approaches:
Using Files.write (small files):
try {
Files.write(p, s.getBytes(), StandardOpenOption.APPEND);
} catch (IOException e) {
System.err.println(e);
}
Using Files.newBufferedWriter(text files):
try (BufferedWriter writer = Files.newBufferedWriter(p, StandardOpenOption.APPEND)) {
writer.write(s);
} catch (IOException ioe) {
System.err.format("IOException: %s%n", ioe);
}
Using Files.newOutputStream (interoperable with java.io APIs):
try (OutputStream out = new BufferedOutputStream(Files.newOutputStream(p, StandardOpenOption.APPEND))) {
out.write(s.getBytes());
} catch (IOException e) {
System.err.println(e);
}
Using Files.newByteChannel (random access files):
try (SeekableByteChannel sbc = Files.newByteChannel(p, StandardOpenOption.APPEND)) {
sbc.write(ByteBuffer.wrap(s.getBytes()));
} catch (IOException e) {
System.err.println(e);
}
Using FileChannel.open (random access files):
try (FileChannel sbc = FileChannel.open(p, StandardOpenOption.APPEND)) {
sbc.write(ByteBuffer.wrap(s.getBytes()));
} catch (IOException e) {
System.err.println(e);
}
Details about these methods can be found in the Oracle's tutorial.
$ens = $em->getRepository('AcmeBinBundle:Marks')

If you want to insert HTML code inside existing page's tag use Jnerator. This tool was created specially for this goal.
Instead of writing next code
var htmlCode = '<ul class=\'menu-countries\'><li
class=\'item\'><img src=\'au.png\'></img><span>Australia </span></li><li
class=\'item\'><img src=\'br.png\'> </img><span>Brazil</span></li><li
class=\'item\'> <img src=\'ca.png\'></img><span>Canada</span></li></ul>';
var element = document.getElementById('myTag');
element.innerHTML = htmlCode;
You can write more understandable structure
var jtag = $j.ul({
class: 'menu-countries',
child: [
$j.li({ class: 'item', child: [
$j.img({ src: 'au.png' }),
$j.span({ child: 'Australia' })
]}),
$j.li({ class: 'item', child: [
$j.img({ src: 'br.png' }),
$j.span({ child: 'Brazil' })
]}),
$j.li({ class: 'item', child: [
$j.img({ src: 'ca.png' }),
$j.span({ child: 'Canada' })
]})
]
});
var htmlCode = jtag.html();
var element = document.getElementById('myTag');
element.innerHTML = htmlCode;

A quicker way for me was to delete the tables and re-add them. It Auto-mapped them. :)
To complete the previous answers, one may need a collection of objects from his CSV File, either parsed by the TextFieldParser or the string.Split method, and then each line converted to an object via Reflection. You obviously first need to define a class that matches the lines of the CSV file.
I used the simple CSV Serializer from Michael Kropat found here: Generic class to CSV (all properties) and reused his methods to get the fields and properties of the wished class.
I deserialize my CSV file with the following method:
public static IEnumerable<T> ReadCsvFileTextFieldParser<T>(string fileFullPath, string delimiter = ";") where T : new()
{
if (!File.Exists(fileFullPath))
{
return null;
}
var list = new List<T>();
var csvFields = GetAllFieldOfClass<T>();
var fieldDict = new Dictionary<int, MemberInfo>();
using (TextFieldParser parser = new TextFieldParser(fileFullPath))
{
parser.SetDelimiters(delimiter);
bool headerParsed = false;
while (!parser.EndOfData)
{
//Processing row
string[] rowFields = parser.ReadFields();
if (!headerParsed)
{
for (int i = 0; i < rowFields.Length; i++)
{
// First row shall be the header!
var csvField = csvFields.Where(f => f.Name == rowFields[i]).FirstOrDefault();
if (csvField != null)
{
fieldDict.Add(i, csvField);
}
}
headerParsed = true;
}
else
{
T newObj = new T();
for (int i = 0; i < rowFields.Length; i++)
{
var csvFied = fieldDict[i];
var record = rowFields[i];
if (csvFied is FieldInfo)
{
((FieldInfo)csvFied).SetValue(newObj, record);
}
else if (csvFied is PropertyInfo)
{
var pi = (PropertyInfo)csvFied;
pi.SetValue(newObj, Convert.ChangeType(record, pi.PropertyType), null);
}
else
{
throw new Exception("Unhandled case.");
}
}
if (newObj != null)
{
list.Add(newObj);
}
}
}
}
return list;
}
public static IEnumerable<MemberInfo> GetAllFieldOfClass<T>()
{
return
from mi in typeof(T).GetMembers(BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static)
where new[] { MemberTypes.Field, MemberTypes.Property }.Contains(mi.MemberType)
let orderAttr = (ColumnOrderAttribute)Attribute.GetCustomAttribute(mi, typeof(ColumnOrderAttribute))
orderby orderAttr == null ? int.MaxValue : orderAttr.Order, mi.Name
select mi;
}
If you want to try it without the try catch block, can use the following method, Create a intent and set the package of the app which you want to verify
val intent = Intent(Intent.ACTION_VIEW)
intent.data = uri
intent.setPackage("com.example.packageofapp")
and the call the following method to check if the app is installed
fun isInstalled(intent:Intent) :Boolean{
val list = context.packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
return list.isNotEmpty()
}

The pandas.DataFrame.dropna function removes missing values (e.g. NaN, NaT).
For example the following code would remove any columns from your dataframe, where all of the elements of that column are missing.
df.dropna(how='all', axis='columns')
The expression $(document).ready(function() deprecated in jQuery3.
See working fiddle with jQuery 3 here
Take into account I didn't include the showless button.
Here's the code:
JS
$(function () {
x=3;
$('#myList li').slice(0, 3).show();
$('#loadMore').on('click', function (e) {
e.preventDefault();
x = x+5;
$('#myList li').slice(0, x).slideDown();
});
});
CSS
#myList li{display:none;
}
#loadMore {
color:green;
cursor:pointer;
}
#loadMore:hover {
color:black;
}
Pattern p = Pattern.compile("[0-9]+");
Matcher m = p.matcher(myString);
while (m.find()) {
int n = Integer.parseInt(m.group());
// append n to list
}
// convert list to array, etc
You can actually replace [0-9] with \d, but that involves double backslash escaping, which makes it harder to read.

The above answer are interesting and very helpful when using Ruby as shell script. For me, I does not use Ruby as my daily language and I prefer to use ruby as flow control only and still use bash to do the tasks.
Some helper function can be used for testing execution result
#!/usr/bin/env ruby
module ShellHelper
def test(command)
`#{command} 2> /dev/null`
$?.success?
end
def execute(command, raise_on_error = true)
result = `#{command}`
raise "execute command failed\n" if (not $?.success?) and raise_on_error
return $?.success?
end
def print_exit(message)
print "#{message}\n"
exit
end
module_function :execute, :print_exit, :test
end
With helper, the ruby script could be bash alike:
#!/usr/bin/env ruby
require './shell_helper'
include ShellHelper
print_exit "config already exists" if test "ls config"
things.each do |thing|
next if not test "ls #{thing}/config"
execute "cp -fr #{thing}/config_template config/#{thing}"
end
This is now supported (since ScalaTest 2.1.3) within interactive mode:
testOnly *MySuite -- -z foo
to run only the tests whose name includes the substring "foo".
For exact match rather than substring, use -t instead of -z.
Change data type of DataFrame column:
To int:
df.column_name = df.column_name.astype(np.int64)
To str:
df.column_name = df.column_name.astype(str)
In your case, the user root won't have any issues. But in certain cases where you're required to login under SSH as a different user, make sure the directory you're scp-ing has adequate permissions for the user you're SSH-ing.
try this one:
var http = require('http');
var fs = require('fs');
var PORT = 8080;
http.createServer((req, res) => {
fs.readFile('./' + req.url, (err, data) => {
if (!err) {
var dotoffset = req.url.lastIndexOf('.');
var mimetype = dotoffset == -1 ? 'text/plaint' : {
'.html': 'text/html',
'.css': 'text/css',
'.js': 'text/javascript',
'.jpg': 'image/jpeg',
'.png': 'image/png',
'.ico': 'image/x-icon',
'.gif': 'image/gif'
}[ req.url.substr(dotoffset) ];
res.setHeader('Content-Type', mimetype);
res.end(data);
console.log(req.url, mimetype);
} else {
console.log('File not fount: ' + req.url);
res.writeHead(404, "Not Found");
res.end();
}
});
}).listen(PORT);
With this, you can include js, css source-codes when linking them and you can load icons, imgs, gifs. And if you want, you can add more if you need.
Another simple way I found for using in LAN is
ssh [username@ip] uname -n

Max has the best solution for when you always want to start both projects, but you can also right click a project and choose menu Debug ? Start New Instance.
This is an option when you only occasionally need to start the second project or when you need to delay the start of the second project (maybe the server needs to get up and running before the client tries to connect, or something).
If you use VisualSVN Server, you can find out the version number by several different means.
Follow these steps to find out the version via the management console:
If you click Version you will also see the versions of the components.
Follow these steps to find out the version from the readme.txt file:
This answer doesn't necessarily scale but only requires minor adjustments as the list grows. Semantically it might seem a little counter-intuitive since it is two lists, but aside from that it'll look the way you want in any browser ever made.

With these examples you will still get an error when trying to round the number 1.005 the solution is to either use a library like Math.js or this function:
function round(value: number, decimals: number) {
return Number(Math.round(value + 'e' + decimals) + 'e-' + decimals);
}
Another cause of SSL errors can be a bad system time – certificates won't validate if it's too far off from the present.
Its always better to go for a generic reusable function in your project which returns whether the extension loaded. You can use the following function to check -
function isExtensionLoaded($extension_name){
return extension_loaded($extension_name);
}
Usage
echo isExtensionLoaded('curl');
echo isExtensionLoaded('gd');
The <select> tag only allows the use of predefined entries. The typical solution to your problem is to have one entry labeled 'Other' and a disabled edit field (<input type="text"). Add some JavaScript to enable the edit field only when 'Other' is selected.
It may be possible to somehow create a dropdown that allows direct editing, but IMO that is not worth the effort. If it was, Amazon, Google or Microsoft would be doing it ;-) Just get the job done with the least complicated solution. It as faster (your boss may like that) and usually easier to maintain (you may like that).
That can be simply done by using this initialization
view.backgroundColor = UIColor(hex: "067AB5")
I added customBinding to the web.config.
<configuration>
<system.serviceModel>
<bindings>
<customBinding>
<binding name="CustomSoapBinding">
<security includeTimestamp="false"
authenticationMode="UserNameOverTransport"
defaultAlgorithmSuite="Basic256"
requireDerivedKeys="false"
messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">
</security>
<textMessageEncoding messageVersion="Soap11"></textMessageEncoding>
<httpsTransport maxReceivedMessageSize="2000000000"/>
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="https://test.com:443/services/testService"
binding="customBinding"
bindingConfiguration="CustomSoapBinding"
contract="testService.test"
name="test" />
</client>
</system.serviceModel>
<startup>
<supportedRuntime version="v4.0"
sku=".NETFramework,Version=v4.0"/>
</startup>
</configuration>
After adding customBinding, I can pass username and password to client service like as follows:
service.ClientCridentials.UserName.UserName = "testUser";
service.ClientCridentials.UserName.Password = "testPass";
In this way you can pass username, password in the header to a SOAP WCF Service.
I faced problem some times so that in this case always avoid FragmentPagerAdapter and use FragmentStatePagerAdapter.
It work for me. I hope it will work for you also.
My implementation:
def get_nested(data, *args):
if args and data:
element = args[0]
if element:
value = data.get(element)
return value if len(args) == 1 else get_nested(value, *args[1:])
Example usage:
>>> dct={"foo":{"bar":{"one":1, "two":2}, "misc":[1,2,3]}, "foo2":123}
>>> get_nested(dct, "foo", "bar", "one")
1
>>> get_nested(dct, "foo", "bar", "two")
2
>>> get_nested(dct, "foo", "misc")
[1, 2, 3]
>>> get_nested(dct, "foo", "missing")
>>>
There are no exceptions raised in case a key is missing, None value is returned in that case.
I would stay away from the reflect. package. Instead use %T
package main
import (
"fmt"
)
func main() {
b := true
s := ""
n := 1
f := 1.0
a := []string{"foo", "bar", "baz"}
fmt.Printf("%T\n", b)
fmt.Printf("%T\n", s)
fmt.Printf("%T\n", n)
fmt.Printf("%T\n", f)
fmt.Printf("%T\n", a)
}

A little late to the party, but I think this does the trick:
mkdir YourRepo
cd YourRepo
git init --bare .git # create a bare repo
git remote add origin REMOTE_URL # add a remote
git fetch origin refs/heads/*:refs/heads/* # fetch heads
git fetch origin refs/tags/*:refs/tags/* # fetch tags
git init # reinit work tree
git checkout master # checkout a branch
If this does something undesirable, I'd love to know. However, so far, this works for me.
Use isinstance:
if isinstance(e, list):
If you want to check that an object is a list or a tuple, pass several classes to isinstance:
if isinstance(e, (list, tuple)):
Normally virtualenv creates environments in the current directory. Unless you're intending to create virtual environments in C:\Windows\system32 for some reason, I would use a different directory for environments.
You shouldn't need to mess with paths: use the activate script (in <env>\Scripts) to ensure that the Python executable and path are environment-specific. Once you've done this, the command prompt changes to indicate the environment. You can then just invoke easy_install and whatever you install this way will be installed into this environment. Use deactivate to set everything back to how it was before activation.
Example:
c:\Temp>virtualenv myenv
New python executable in myenv\Scripts\python.exe
Installing setuptools..................done.
c:\Temp>myenv\Scripts\activate
(myenv) C:\Temp>deactivate
C:\Temp>
Notice how I didn't need to specify a path for deactivate - activate does that for you, so that when activated "Python" will run the Python in the virtualenv, not your system Python. (Try it - do an import sys; sys.prefix and it should print the root of your environment.)
You can just activate a new environment to switch between environments/projects, but you'll need to specify the whole path for activate so it knows which environment to activate. You shouldn't ever need to mess with PATH or PYTHONPATH explicitly.
If you use Windows Powershell then you can take advantage of a wrapper. On Linux, the virtualenvwrapper (the link points to a port of this to Powershell) makes life with virtualenv even easier.
Update: Not incorrect, exactly, but perhaps not quite in the spirit of virtualenv. You could take a different tack: for example, if you install Django and anything else you need for your site in your virtualenv, then you could work in your project directory (where you're developing your site) with the virtualenv activated. Because it was activated, your Python would find Django and anything else you'd easy_installed into the virtual environment: and because you're working in your project directory, your project files would be visible to Python, too.
Further update: You should be able to use pip, distribute instead of setuptools, and just plain python setup.py install with virtualenv. Just ensure you've activated an environment before installing something into it.
Given your example, you need to add the following import in your main.main class:
import second.second;
Some bonus advice, make sure you titlecase your class names as that is a Java standard. So your example Main class will have the structure:
package main; //lowercase package names
public class Main //titlecase class names
{
//Main class content
}
The ifelse function would be a quick and easy way to do this.
How about this?
Using change and get the value of radio type is checked...

cat ~/file_on_host.txt | vagrant ssh -c 'cat - > ~/file_on_guest.txt'
vagrant ssh -c 'cat ~/file_on_guest.txt' > ~/file_on_host.txt
No need for plugins or guest reloads. Just make sure to provide vagrant box ID to 'vagrant ssh' if you are not in the same dir as the Vagrantfile. Tested on Vagrant v1.8.1.
You can create Custom date picker, that is work for all api levels.
public class CustomDatePickerDialog extends DatePickerDialog {
int maxYear;
int maxMonth;
int maxDay;
public CustomDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {
super(context, callBack, year, monthOfYear, dayOfMonth);
}
public void setMaxDate(long maxDate) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
getDatePicker().setMaxDate(System.currentTimeMillis());
} else {
final Calendar c = Calendar.getInstance();
c.setTimeInMillis(maxDate);
maxYear = c.get(Calendar.YEAR);
maxMonth = c.get(Calendar.MONTH);
maxDay = c.get(Calendar.DAY_OF_MONTH);
}
}
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
super.onDateChanged(view, year, monthOfYear, dayOfMonth);

view.updateDate(maxYear, maxMonth, maxDay);
}
}
set max date
final CustomDatePickerDialog pickerDialog = new CustomDatePickerDialog(getActivity(),
myDateListener, year, month, day);
pickerDialog.setMaxDate(System.currentTimeMillis());
pickerDialog.show();
I had installed PHP in IIS7 on Windows Server 2008 R2 using the Web Platform Installer. It did not work out of the box. I had to install the Visual C++ Redistributable for VS 2012 Update 4 (32bit) as found here http://www.microsoft.com/en-us/download/details.aspx?id=30679 .
Similar to Andrews which is #1:
Something that worked for me is:
name = "Blue Jeans"
Product.find_by("lower(name) = ?", name.downcase)
This eliminates the need to do a #where and #first in the same query. Hope this helps!
For new Android Studio versions, go to C:\Program Files\Android\Android Studio\jre\bin(or to location of Android Studio installed files) and open command window at this location and type in following command in command prompt:-

I found several posts telling me to run several gpg commands, but they didn't solve the problem because of two things. First, I was missing the debian-keyring package on my system and second I was using an invalid keyserver. Try different keyservers if you're getting timeouts!
Thus, the way I fixed it was:
apt-get install debian-keyring
gpg --keyserver pgp.mit.edu --recv-keys 1F41B907
gpg --armor --export 1F41B907 | apt-key add -
Then running a new "apt-get update" worked flawlessly!
What is web.xml file and what all things can I do with it ?
The /WEB-INF/web.xml file is the Web Application Deployment Descriptor of your application. This file is an XML document that defines everything about your application that a server needs to know (except the context path, which is assigned by the Application Deployer and Administrator when the application is deployed): servlets and other components like filters or listeners, initialization parameters, container-managed security constraints, resources, welcome pages, etc.
Note that reference you mentioned is pretty old (Java EE 1.4), there have been few changes in Java EE 5 and even more in Java EE 6 (which makes the web.xml "optional" and introduces Web Fragments).
Is there any configuration parameter which should be avoided like plague?
No.
Any parameters related to performance or memory usage?
No, such things are not configured at the application level but at the container level.
Security related risk due to common mis-configuration ?
Well, if you want to use container-managed security constraints and fail at configuring them properly, resources won't obviously be properly protected. Apart from that, the biggest security risks come from the code you'll deploy IMO.
// WPF
// Defined Color
button1.Background = Brushes.Green;
// Color from RGB
button2.Background = new SolidColorBrush(Color.FromArgb(255, 0, 255, 0));
This would do the job:
Double.parseDouble(p.replace(',','.'));
Use the basic Math methods:
Math.random() returns a random number between 0 and 1 (including 0, excluding 1).Round this number downward to its nearest integer
Math.floor(Math.random()*10) + 1
Example:
//Example, including customisable intervals [lower_bound, upper_bound)
var limit = 10,
amount = 3,
lower_bound = 1,
upper_bound = 10,
unique_random_numbers = [];
if (amount > limit) limit = amount; //Infinite loop if you want more unique
//Natural numbers than exist in a
// given range
while (unique_random_numbers.length < limit) {
var random_number = Math.floor(Math.random()*(upper_bound - lower_bound) + lower_bound);
if (unique_random_numbers.indexOf(random_number) == -1) {
// Yay! new random number
unique_random_numbers.push( random_number );
}
}
// unique_random_numbers is an array containing 3 unique numbers in the given range
If you're like me and came here looking for a way to make sass --watch work with compass, the answer is to use Compass' version of watch, simply:
compass watch
If you're on a Mac and don't yet have the gem installed, you might run into errors when you try to install the Compass gem, due to permission problems that arise on OSX versions later than 10.11. Install ruby with Homebrew to get around this. See this answer for how to do that.
Alternatively you could just use CodeKit, but if you're stubborn like me and want to use Sublime Text and command line, this is the route to go.
You can use this code for toggle your element var ele = jQuery("yourelementid"); ele.slideToggle('slow'); this will work for you :)
For Linux users using KVM and facing this problem try setting the Graphics option on the Android Virtual Device to Software instead of Automatic or Hardware . As previously mentioned in this answer.
I can confirm that the method works for Arch Linux, Ubuntu 16.04, as well as windows with or without a proprietary graphics card using Android Studio version 2.3.1+
As described by the others, writing to /dev/null eliminates the output of a program. Usually cron sends an email for every output from the process started with a cronjob. So by writing the output to /dev/null you prevent being spammed if you have specified your adress in cron.
uint32_t is defined in the standard, in
<cstdint> synopsis [cstdint.syn]namespace std {
//...
typedef unsigned integer type uint32_t; // optional
//...
}
uint32 is not, it's a shortcut provided by some compilers (probably as typedef uint32_t uint32) for ease of use.
You could do the opposite of what you proposed.
location (/test)/ {
set $folder $1;
}
location (/test_/something {
set $folder $1;
}
Had the same problem. If server is configured correctly and .htacces is not the answer, might want to look the svg source you are embedding. Mine were created with text editor, rendered well on Chrome&Safari inside html5 code, once embedded, nothing was visible. Added correct version, dimensions etc to the svg code and works like a charm. Also, all styles inline.
Ie
<svg version="1.1" baseProfile="full" width="24" height="24" xmlns="http://www.w3.org/2000/svg">
<rect x="0" y="0" rx="2" ry="2" width="24" height="24" style="fill:#fbc800;width:24px;height:24px;" />
</svg>
This variation of the query (as explained in other answers) worked for me.
SELECT
COLUMN_NAME
FROM
information_schema.COLUMNS
WHERE
TABLE_NAME = 'city';
It's described here in details: http://www.postgresqltutorial.com/postgresql-describe-table/
Union is not what you want. You want to use joins to create single rows. It's a little unclear what constitutes a unique row in your tables and how they really relate to each other and it's also unclear if one table will have rows for every country in every year. But I think this will work:
CREATE VIEW V AS (
SELECT i.country,i.year,p.pop,f.food,i.income FROM
INCOME i
LEFT JOIN
POP p
ON
i.country=p.country
LEFT JOIN
Food f
ON
i.country=f.country
WHERE
i.year=p.year
AND
i.year=f.year
);
The left (outer) join will return rows from the first table even if there are no matches in the second. I've written this assuming you would have a row for every country for every year in the income table. If you don't things get a bit hairy as MySQL does not have built in support for FULL OUTER JOINs last I checked. There are ways to simulate it, and they would involve unions. This article goes into some depth on the subject: http://www.xaprb.com/blog/2006/05/26/how-to-write-full-outer-join-in-mysql/
I had the same issue, due to the fact that I had all the configuration that describe in this post, but in my case was because I had two jquery imports (one of them was primefaces's query) which caused conflicts to upload files.
{{ path(app.request.attributes.get('_route'),
app.request.attributes.get('_route_params')) }}
If you want to read it into a view variable:
{% set currentPath = path(app.request.attributes.get('_route'),
app.request.attributes.get('_route_params')) %}
The app global view variable contains all sorts of useful shortcuts, such as app.session and app.security.token.user, that reference the services you might use in a controller.
I had the same problem. My project layout looked like
\---super
\---thirdparty
+---mod1-root
| +---mod1-linux32
| \---mod1-win32
\---mod2-root
+---mod2-linux32
\---mod2-win32
In my case, I had a mistake in my pom.xmls at the modX-root-level. I had copied the mod1-root tree and named it mod2-root. I incorrectly thought I had updated all the pom.xmls appropriately; but in fact, mod2-root/pom.xml had the same group and artifact ids as mod1-root/pom.xml. After correcting mod2-root's pom.xml to have mod2-root specific maven coordinates my issue was resolved.
Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.
- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.
A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).
R only knows how to apply + (and other binary operators, such as -) to numeric arguments:
> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator
When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.
EDIT:
Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:
> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator
> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3
Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.
I use the AdWords API, and sometimes I have the same problem. My solution is to add ini_set('default_socket_timeout', 900); on the file vendor\googleads\googleads-php-lib\src\Google\AdsApi\AdsSoapClient.php line 65
and in the vendor\googleads-php-lib\src\Google\AdsApi\Adwords\Reporting\v201702\ReportDownloader.php line 126 ini_set('default_socket_timeout', 900); $requestOptions['stream_context']['http']['timeout'] = "900";
Google package overwrite the default php.ini parameter.
Sometimes, the page could connect to 'https://adwords.google.com/ap i/adwords/mcm/v201702/ManagedCustomerService?wsdl and sometimes no. If the page connects once, The WSDL cache will contain the same page, and the program will be ok until the code refreshes the cache...
I have a simple example here to display date and time with Millisecond......
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class MyClass{
public static void main(String[]args){
LocalDateTime myObj = LocalDateTime.now();
DateTimeFormatter myFormat = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS);
String forDate = myObj.format(myFormat);
System.out.println("The Date and Time are: " + forDate);
}
}
C# 4.0 also supports optional parameters, which could be useful in some other situations. See this article.
Why not use glob()?
#include <glob.h>
glob_t glob_result;
glob("/your_directory/*",GLOB_TILDE,NULL,&glob_result);
for(unsigned int i=0; i<glob_result.gl_pathc; ++i){
cout << glob_result.gl_pathv[i] << endl;
}
The answer of crdunst is pretty neat and the best looking answer I've found but there's no explanation on how to use and the code is bigger than needed.
The only code you need:
#element {
background-color: #cacbcf;
text-shadow: 2px 2px 4px rgba(0,0,0, 0.5);
filter: chroma(color=#cacbcf) progid:DXImageTransform.Microsoft.dropshadow(color=#60000000, offX=2, offY=2);
}
First you MUST specify a background-color - if your element should be transparent just copy the background-color of the parent or let it inherit. The color at the chroma-filter must match the background-color to fix those artifacts around the text (but here you must copy the color, you can't write inherit). Note that I haven't shortened the dropshadow-filter - it works but the shadows are then cut to the element dimensions (noticeable with big shadows; try to set the offsets to atleast 4).
TIP: If you want to use colors with transparency (alpha-channel) write in a #AARRGGBB notation, where AA stands for a hexadezimal value of the opacity - from 01 to FE, because FF and ironically also 00 means no transparency and is therefore useless.. ^^ Just go a little lower than in the rgba notation because the shadows aren't soft and the same alpha value would appear darker then. ;)
A nice snippet to convert the alpha value for IE (JavaScript, just paste into the console):
var number = 0.5; //alpha value from the rgba() notation
("0"+(Math.round(0.75 * number * 255).toString(16))).slice(-2);
ISSUES: The text/font behaves like an image after the shadow is applied; it gets pixelated and blurry after you zoom in... But that's IE's issue, not mine.
Live demo of the shadow here: http://jsfiddle.net/12khvfru/2/
The os.makedirs function does this. Try the following:
import os
import errno
filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
try:
os.makedirs(os.path.dirname(filename))
except OSError as exc: # Guard against race condition
if exc.errno != errno.EEXIST:
raise
with open(filename, "w") as f:
f.write("FOOBAR")
The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.
In Python 3.2+, there is a more elegant way that avoids the race condition above:
import os
filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
f.write("FOOBAR")
Although this thread is 3 years old, here is my solution:
$(function ()
{
keep_fields_uptodate();
});
function keep_fields_uptodate()
{
// Keep all fields up to date!
var $inputDate = $("input[type='date']");
$inputDate.blur(function(event)
{
$("input").trigger("change");
});
}
This project https://github.com/FilipDeVos/sp_select has a stored procedure sp_select which allows for selecting from a temp table.
Usage:
exec sp_select 'tempDb..#myTempTable'
While debugging a stored procedure you can open a new tab and run this command to see the contents of the temp table.
While the OP may be working on a nix platform this answer could help non-nix platforms. I have not experienced the shebang approach work in Microsoft Windows.
Rephrased: The shebang line answers your question of "within my script" but I believe only for Unix-like platforms. Even though it is the Unix shell, outside the script, that actually interprets the shebang line to determine which version of Python interpreter to call. I am not sure, but I believe that solution does not solve the problem for Microsoft Windows platform users.
In the Microsoft Windows world, the simplify the way to run a specific Python version, without environment variables setup specifically for each specific version of Python installed, is just by prefixing the python.exe with the path you want to run it from, such as C:\Python25\python.exe mymodule.py or D:\Python27\python.exe mymodule.py
However you'd need to consider the PYTHONPATH and other PYTHON... environment variables that would point to the wrong version of Python libraries.
For example, you might run: C:\Python2.5.2\python.exe mymodule
Yet, the environment variables may point to the wrong version as such:
PYTHONPATH = D:\Python27
PYTHONLIB = D:\Python27\lib
Loads of horrible fun!
So a non-virtualenv way, in Windows, would be to use a batch file that sets up the environment and calls a specific Python executable via prefixing the python.exe with the path it resides in. This way has additional details you'll have to manage though; such as using command line arguments for either of the "start" or "cmd.exe" command to "save and replace the "console" environment" if you want the console to stick around after the application exits.
Your question leads me to believe you have several Python modules, each expecting a certain version of Python. This might be solvable "within" the script by having a launching module which uses the subprocess module. Instead of calling mymodule.py you would call a module that calls your module; perhaps launch_mymodule.py
import sys
import subprocess
if sys.argv[2] == '272':
env272 = {
'PYTHONPATH': 'blabla',
'PYTHONLIB': 'blabla', }
launch272 = subprocess.Popen('D:\\Python272\\python.exe mymodule.py', env=env272)
if sys.argv[1] == '252'
env252 = {
'PYTHONPATH': 'blabla',
'PYTHONLIB': 'blabla', }
launch252 = subprocess.Popen('C:\\Python252\\python.exe mymodule.py', env=env252)
I have not tested this.
awk '!seen[$0]++' file.txt
seen is an associative-array that Awk will pass every line of the file to. If a line isn't in the array then seen[$0] will evaluate to false. The ! is the logical NOT operator and will invert the false to true. Awk will print the lines where the expression evaluates to true. The ++ increments seen so that seen[$0] == 1 after the first time a line is found and then seen[$0] == 2, and so on.
Awk evaluates everything but 0 and "" (empty string) to true. If a duplicate line is placed in seen then !seen[$0] will evaluate to false and the line will not be written to the output.
When finding multiple occurrences of a substring matching a pattern
String input_string = "foo/adsfasdf/adf/bar/erqwer/";
String regex = "(foo/|bar/)"; // Matches 'foo/' and 'bar/'
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(input_string);
while(matcher.find()) {
String str_matched = input_string.substring(matcher.start(), matcher.end());
// Do something with a match found
}
I tried this tool and it gave me good results.
I would try the usual remedial things: - Run Rob Bovey's VBA Code Cleaner on your VBA Code - remove all addins on the users PC, particularly COM and .NET addins - Delete all the users .EXD files (MSoft Update incompatibilities) - Run Excel Detect & Repair on the users system - check the size of the user's .xlb file (should be 20-30K) - Reboot then delete all the users Temp files

I had this issue when I was trying to render an object on a child component that was receiving props.
I fixed this when I realized that my code was trying to render an object and not the object key's value that I was trying to render.

Its a very customizable to display PDF's directly in your browser. It basically hosts the PDF in a flash object if you are not opposed to that sort of thing.
Here is a sample from our corporate website.
Use std::cout, since cout is defined within the std namespace. Alternatively, add a using std::cout; directive.
Another way to use key($array) in a foreach loop is by using next($array) at the end of the loop, just make sure each iteration calls the next() function (in case you have complex branching inside the loop)
Common Resource Grep (crgrep) will search for string matches in tables/columns by name or content and supports a number of DBs, including SQLServer, Oracle and others. Full wild-carding and other useful options.
It's opensource (I'm the author).
In my case I have created function like this to make Post request which takes String url and hashmap of parameters
public String postRequest( String mainUrl,HashMap<String,String> parameterList)
{
String response="";
try {
URL url = new URL(mainUrl);
StringBuilder postData = new StringBuilder();
for (Map.Entry<String, String> param : parameterList.entrySet())
{
if (postData.length() != 0) postData.append('&');
postData.append(URLEncoder.encode(param.getKey(), "UTF-8"));
postData.append('=');
postData.append(URLEncoder.encode(String.valueOf(param.getValue()), "UTF-8"));
}
byte[] postDataBytes = postData.toString().getBytes("UTF-8");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
conn.setRequestProperty("Content-Length", String.valueOf(postDataBytes.length));
conn.setDoOutput(true);
conn.getOutputStream().write(postDataBytes);
Reader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
StringBuilder sb = new StringBuilder();
for (int c; (c = in.read()) >= 0; )
sb.append((char) c);
response = sb.toString();
return response;

I ran into a field where .clear() did not work. Using a combination of the first two answers worked for this field.

SELECT IFNULL(SUM(Column1), 0) AS total FROM...
SELECT COALESCE(SUM(Column1), 0) AS total FROM...
The difference between them is that IFNULL is a MySQL extension that takes two arguments, and COALESCE is a standard SQL function that can take one or more arguments. When you only have two arguments using IFNULL is slightly faster, though here the difference is insignificant since it is only called once.
Maybe I am 6.5 years late. But I'm answering because others maybe searching still now. I faced the same problem and was searching everywhere. But then I realized I had written my code in an empty file. If you create a project and write your code in there, there won't be this error.
Today, I mistakenly checked out on a commit and started working on it, making some commits on a detach HEAD state. Then I pushed to the remote branch using the following command:
git push origin HEAD: <My-remote-branch>
Then
git checkout <My-remote-branch>
Then
git pull
I finally got my all changes in my branch that I made in detach HEAD.
The JVM will start with memory useage at the initial heap level. If the maxheap is higher, it will grow to the maxheap size as memory requirements exceed it's current memory.
So,
JVM starts with 512 M, never resizes.
JVM starts with 64M, grows (up to max ceiling of 512) if mem. requirements exceed 64.
In front-end JavaScript/HTML, you can load a binary file as an image, you do not have to convert to base64:
<img src="http://engci.nabisco.com/artifactory/repo/folder/my-image">
my-image is a binary image file. This will load just fine.

If you are in the fragment itself, you need to call this. Your fragment needs to be the fragment that is being called. Enter code:

or if you are using supportLib, then you need to call:
getSupportFragmentManager().beginTransaction().remove(yourFragment).commitAllowingStateLoss();

parentElement.prepend(newFirstChild);
This is a new addition in (likely) ES7. It is now vanilla JS, probably due to the popularity in jQuery. It is currently available in Chrome, FF, and Opera. Transpilers should be able to handle it until it becomes available everywhere.
P.S. You can directly prepend strings
parentElement.prepend('This text!');

For simple iteration of key/values, sometimes libraries like underscorejs can be your friend.
const _ = require('underscore');
_.each(a, function (value, key) {

just for reference
useState is a hook that lets you add state to a functional component. It accepts an argument which is the initial value of the state property and returns the current value of state property and a method which is capable of updating that state property.
Following is a simple example:
import React, {useState} from react
function HookCounter {
const [count, stateCount]= useState(0)
return(
<div>
<button onClick{( ) => setCount(count+1)}> count{count}</button>
</div>
)
}
useState accepts the initial value of the state variable which is zero in this case and returns a pair of values. The current value of the state has been called count and a method that can update the state variable has been called as setCount.
Yes, you need to specify the encoding of the file you want to read.
Yes, this means that you have to know the encoding of the file you want to read.
No, there is no general way to guess the encoding of any given "plain text" file.
The one-arguments constructors of FileReader always use the platform default encoding which is generally a bad idea.
Since Java 11 FileReader has also gained constructors that accept an encoding: new FileReader(file, charset) and new FileReader(fileName, charset).
In earlier versions of java, you need to use new InputStreamReader(new FileInputStream(pathToFile), <encoding>).
i'd use the pandas replace function, very simple and powerful as you can use regex. Below i'm using the regex \D to remove any non-digit characters but obviously you could get quite creative with regex.
data['result'].replace(regex=True,inplace=True,to_replace=r'\D',value=r'')
You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,
df['Col3'] = (df['Col2'] <= 1).astype(int)
If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:
df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)
Or:
df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55
I used this code:

If you want to get a class name from inside a class method, class.name or self.class.name won't work. These will just output Class, since the class of a class is Class. Instead, you can just use name:
module Foo
class Bar
def self.say_name
puts "I'm a #{name}!"
end
end
end
Foo::Bar.say_name
output:
I'm a Foo::Bar!
Click the line number, and then copy and paste the link from the address bar. To select a range, click the number, and then shift click the later number.
Alternatively, the links are a relatively simple format, just append #L<number> to the end for that specific line number, using the link to the file. Here's a link to the third line of the git repository's README:
https://github.com/git/git/blob/master/README#L3
Define the width as 960px, or whatever you prefer, and you're good to go!
#main {

}
(I couldn't figure this out until I fixed the width, nothing else worked.)

Disabling a html button

All versions of jQuery prior to 1.6
Disabling a html button
$('#Button').attr('disabled','disabled');
Enabling a html button
$('#Button').removeAttr('disabled');
All versions of jQuery after 1.6
Disabling a html button
$('#Button').prop('disabled', true);
Enabling a html button

P.S. Updated the code based on jquery 1.6.1 changes. As a suggestion, always use the latest jquery files and the prop() method.
A slightly modified version of Brian's answer allows optional management of read start, This seems to be the easiest method. probably not the most efficient, but easy to understand and use.
Public Function ReadAll(ByVal memStream As MemoryStream, Optional ByVal startPos As Integer = 0) As String
' reset the stream or we'll get an empty string returned
' remember the position so we can restore it later
Dim Pos = memStream.Position
memStream.Position = startPos
Dim reader As New StreamReader(memStream)
Dim str = reader.ReadToEnd()
' reset the position so that subsequent writes are correct
memStream.Position = Pos
Return str
End Function

Visually you can open "SQL Server Configuration Manager" and check properties of "Network Configuration":
I have cuDNN 8.0 and none of the suggestions above worked for me. The desired information was in /usr/include/cudnn_version.h, so
cat /usr/include/cudnn_version.h | grep CUDNN_MAJOR -A 2
did the trick.
Does this not work (assuming "ROUTERNAME" is the user name the router expects)?
net use Z: "\\10.0.1.1\DRIVENAME" /user:"ROUTERNAME" "PW"
Alternatively, you can use use a small VBScript:
Option Explicit
Dim u, p, s, l
Dim Network: Set Network= CreateObject("WScript.Network")
l = "Z:"
s = "\\10.0.1.1\DRIVENAME"
u = "ROUTERNAME"
p = "PW"
Network.MapNetworkDrive l, s, False, u, p
If you want to know the number of visitors (as is titled in the question) and not the number of pageviews, then you'll need to create a custom report.
Google Analytics has changed the terminology they use within the reports. Now, visits is named "sessions" and unique visitors is named "users."
User - A unique person who has visited your website. Users may visit your website multiple times, and they will only be counted once.
Session - The number of different times that a visitor came to your site.
Pageviews - The total number of pages that a user has accessed.
I think the biggest argument for functional programming languages to become the "next big thing" is that in the future multi-core processors will be the norm. Programmers will have to take advantage of that, and functional programming offers really wonderful possibilities for building top of the line concurrent software.
P.S. When I was in college at Boston University ('98-'02) we spent a semester learning Scheme which is a close cousin of LISP. When we first started learning it, I wanted to rip my hair out. By the end of the course it was very natural.

msnodesql is working out great for me. Here is a sample:

express = require('express'),
app = express(),
nconf = require('nconf')
nconf.env()
.file({ file: 'config.json' });
var conn = nconf.get("SQL_CONN");
var conn_str = "Driver={SQL Server Native Client 11.0};Server=server.name.here;Database=Product;Trusted_Connection={Yes}";
app.get('/api/brands', function(req, res){
var data = [];
var jsonObject = {};
mssql.open(conn_str, function (err, conn) {
if (err) {
console.log("Error opening the connection!");
return;
}
conn.queryRaw("dbo.storedproc", function (err, results) {
if(err) {
console.log(err);
res.send(500, "Cannot retrieve records.");
}
else {
//res.json(results);
for (var i = 0; i < results.rows.length; i++) {
var jsonObject = new Object()
for (var j = 0; j < results.meta.length; j++) {
paramName = results.meta[j].name;
paramValue = results.rows[i][j];
jsonObject[paramName] = paramValue;
}
data.push(jsonObject); //This is a js object we are jsonizing not real json until res.send
}
res.send(data);
}
});
});
});
One of simplest solution is to change colorPrimary from colors.xml file.
To do with javascript you could do something like this:
<script type="Text/javascript">
var text = <?= $text_from_db; ?>
</script>
Then you can use whatever you want in your javascript to put the text var into the textbox.
This worked for me.
string stringSeparators = "\r\n";
string text = sr.ReadToEnd();
string lines = text.Replace(stringSeparators, "");
lines = lines.Replace("\\r\\n", "\r\n");
Console.WriteLine(lines);
The first replace replaces the \r\n from the text file's new lines, and the second replaces the actual \r\n text that is converted to \\r\\n when the files is read. (When the file is read \ becomes \\).

According to Apple documentation of NSDate compare:
Returns an NSComparisonResult value that indicates the temporal ordering of the receiver and another given date.
- (NSComparisonResult)compare:(NSDate *)anotherDateParameters
anotherDateThe date with which to compare the receiver. This value must not be nil. If the value is nil, the behavior is undefined and may change in future versions of Mac OS X.
Return Value
If:
The receiver and anotherDate are exactly equal to each other,
NSOrderedSameThe receiver is later in time than anotherDate,
NSOrderedDescendingThe receiver is earlier in time than anotherDate,
NSOrderedAscending
In other words:
if ([date1 compare:date2] == NSOrderedSame) ...
Note that it might be easier in your particular case to read and write this :
if ([date2 isEqualToDate:date2]) ...
Another possibility is to use the clipboard to copy and paste the results directly into Excel. Just be careful with General type Excel columns, as they can sometimes have unpredictable results, depending on your data. CTL-A anywhere in the result grid, and then right-click:
If you have trouble with Excel's General format doing undesired conversions, select the blank columns in Excel before you paste and change the format to "text".

unique and random are mutually exclusive. perhaps you want this?
import random
def uniqueid():
seed = random.getrandbits(32)
while True:
yield seed
seed += 1
Usage:
unique_sequence = uniqueid()
id1 = next(unique_sequence)
id2 = next(unique_sequence)
id3 = next(unique_sequence)
ids = list(itertools.islice(unique_sequence, 1000))
no two returned id is the same (Unique) and this is based on a randomized seed value
