I ran into the same problem earlier, but solved it in a way slightly different from what we have here. So, I thought I'd add my way as well. Hopefully, it will help someone!
sudo apt-get install mysql-client
didn't work for me. However, I have Homebrew already installed. So, instead, I tried:
brew install mysql-client
Now, I don't get the error any more.
Good luck!
using System;
using System.Security;
class Sample {
static void Main() {
string text = "Escape characters : < > & \" \'";
string xmlText = SecurityElement.Escape(text);
//output:
//Escape characters : < > & " '
Console.WriteLine(xmlText);
}
}
Easy way of doing it would be:
<input type="file" accept=".gif,.jpg,.jpeg,.png,.doc,.docx">
Works with all browsers, except IE9. I haven't tested it in IE10+.
There should be no difference at all maybe the first is a little more performant but i think it's trivial ( you shouldn't worry about this, really ).
With both you wrap the <body>
tag in a jQuery object

As an improvement to the accepted answer, in order to reduce nesting, you could do this instead, provided that the key is not inherited:
for (var key in dictionary) {
if (!dictionary.hasOwnProperty(key)) {
continue;
}
console.log(key, dictionary[key]);
}
Edit: info about Object.hasOwnProperty

var ofd = new Microsoft.Win32.OpenFileDialog() {Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"};
var result = ofd.ShowDialog();
if (result == false) return;
textBox1.Text = ofd.FileName;
You can use the java.time
package (since Java8 and late) to get start/end of day/week/month.
The util class example below:
import org.junit.Test;
import java.time.DayOfWeek;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.ZoneId;
import java.time.format.DateTimeFormatter;
import java.time.temporal.TemporalAdjusters;
import java.util.Date;
public class DateUtil {

public static LocalDateTime startOfDay() {
return LocalDateTime.now(DEFAULT_ZONE_ID).with(LocalTime.MIN);
}
public static LocalDateTime endOfDay() {
return LocalDateTime.now(DEFAULT_ZONE_ID).with(LocalTime.MAX);
}
public static boolean belongsToCurrentDay(final LocalDateTime localDateTime) {
return localDateTime.isAfter(startOfDay()) && localDateTime.isBefore(endOfDay());
}
//note that week starts with Monday
public static LocalDateTime startOfWeek() {
return LocalDateTime.now(DEFAULT_ZONE_ID)
.with(LocalTime.MIN)
.with(TemporalAdjusters.previousOrSame(DayOfWeek.MONDAY));
}
//note that week ends with Sunday
public static LocalDateTime endOfWeek() {
return LocalDateTime.now(DEFAULT_ZONE_ID)
.with(LocalTime.MAX)
.with(TemporalAdjusters.nextOrSame(DayOfWeek.SUNDAY));
}
public static boolean belongsToCurrentWeek(final LocalDateTime localDateTime) {
return localDateTime.isAfter(startOfWeek()) && localDateTime.isBefore(endOfWeek());
}
public static LocalDateTime startOfMonth() {
return LocalDateTime.now(DEFAULT_ZONE_ID)
.with(LocalTime.MIN)
.with(TemporalAdjusters.firstDayOfMonth());
}
public static LocalDateTime endOfMonth() {
return LocalDateTime.now(DEFAULT_ZONE_ID)
.with(LocalTime.MAX)
.with(TemporalAdjusters.lastDayOfMonth());
}
public static boolean belongsToCurrentMonth(final LocalDateTime localDateTime) {
return localDateTime.isAfter(startOfMonth()) && localDateTime.isBefore(endOfMonth());
}
public static long toMills(final LocalDateTime localDateTime) {
return localDateTime.atZone(DEFAULT_ZONE_ID).toInstant().toEpochMilli();
}
public static Date toDate(final LocalDateTime localDateTime) {
return Date.from(localDateTime.atZone(DEFAULT_ZONE_ID).toInstant());
}
public static String toString(final LocalDateTime localDateTime) {
return localDateTime.format(DateTimeFormatter.ISO_DATE_TIME);
}
@Test
public void test() {
//day
final LocalDateTime now = LocalDateTime.now();
System.out.println("Now: " + toString(now) + ", in mills: " + toMills(now));
System.out.println("Start of day: " + toString(startOfDay()));

System.out.println("Does '" + toString(yesterday) + "' belong to the current day? > " + belongsToCurrentDay(yesterday));
final LocalDateTime tomorrow = now.plusDays(1);
System.out.println("Does '" + toString(tomorrow) + "' belong to the current day? > " + belongsToCurrentDay(tomorrow));
//week
System.out.println("Start of week: " + toString(startOfWeek()));
System.out.println("End of week: " + toString(endOfWeek()));
System.out.println("Does '" + toString(now) + "' belong to the current week? > " + belongsToCurrentWeek(now));
final LocalDateTime previousWeek = now.minusWeeks(1);
System.out.println("Does '" + toString(previousWeek) + "' belong to the current week? > " + belongsToCurrentWeek(previousWeek));
final LocalDateTime nextWeek = now.plusWeeks(1);
System.out.println("Does '" + toString(nextWeek) + "' belong to the current week? > " + belongsToCurrentWeek(nextWeek));
//month
System.out.println("Start of month: " + toString(startOfMonth()));

final LocalDateTime nextMonth = now.plusMonths(1);
System.out.println("Does '" + toString(nextMonth) + "' belong to the current month? > " + belongsToCurrentMonth(nextMonth));
}
}

You may not have permission to dba_sequences. So you can always just do:
select * from user_sequences;
Just wanted to share a curiosity:
when using the onkeydown event to activate a JS method, the charcode for that event is NOT the same as the one you get with onkeypress!
For instance the numpad keys will return the same charcodes as the number keys above the letter keys when using onkeypress, but NOT when using onkeydown !
Took me quite a few seconds to figure out why my script which checked for certain charcodes failed when using onkeydown!
Demo: https://www.w3schools.com/code/tryit.asp?filename=FMMBXKZLP1MK
and yes. I do know the definition of the methods are different.. but the thing that is very confusing is that in both methods the result of the event is retrieved using event.keyCode.. but they do not return the same value.. not a very declarative implementation.
Just use the following methods to create a 2-D vector.
int rows, columns;
// . . .
vector < vector < int > > Matrix(rows, vector< int >(columns,0));
OR
vector < vector < int > > Matrix;
Matrix.assign(rows, vector < int >(columns, 0));
//Do your stuff here...
This will create a Matrix of size rows * columns and initializes it with zeros because we are passing a zero(0) as a second argument in the constructor i.e vector < int > (columns, 0).
Best Practice
As mentioned in the comment to the first answer, the best practice is to use the PHP constant PHP_EOL which represents the current system's EOL (End Of Line).
$skuList = explode(PHP_EOL, $_POST['skuList']);
PHP provides a lot of other very useful constants that you can use to make your code system independent, see this link to find useful and system independent directory constants.
Warning
These constants make your page system independent, but you might run into problems when moving from one system to another when you use the constants with data stored on another system. The new system's constants might be different from the previous system's and the stored data might not work anymore. So completely parse your data before storing it to remove any system dependent parts.
UPDATE
Andreas' comment made me realize that the 'Best Practice' solution I present here does not apply to the described use-case: the server's EOL (PHP) does not have anything to do with the EOL the browser (any OS) is using, but that (the browser) is where the string is coming from.
So please use the solution from @Alin_Purcaru (three down) to cover all your bases (and upvote his answer):
$skuList = preg_split('/\r\n|\r|\n/', $_POST['skuList']);
And then there is the original plugin ez-on-da-ice. Better yet, you can complain to me directly if there are issues. I promise you, I am mostly very responsive :).
Using Following Code You Solve thisQuestion.... If you run a file using localhost server than this problem solve by following Jsp Page Code.This Code put Between Head Tag in jsp file

The jsoncons C++ header-only library also supports conversion between JSON text and C++ objects. Decode and encode are defined for all C++ classes that have json_type_traits defined. The standard library containers are already supported, and json_type_traits can be specialized for user types in the jsoncons namespace.
Below is an example:
#include <iostream>
#include <jsoncons/json.hpp>
namespace ns {
enum class hiking_experience {beginner,intermediate,advanced};
class hiking_reputon
{
std::string rater_;
hiking_experience assertion_;
std::string rated_;
double rating_;
public:
hiking_reputon(const std::string& rater,
hiking_experience assertion,
const std::string& rated,
double rating)
: rater_(rater), assertion_(assertion), rated_(rated), rating_(rating)
{
}
const std::string& rater() const {return rater_;}
hiking_experience assertion() const {return assertion_;}
const std::string& rated() const {return rated_;}
double rating() const {return rating_;}
};
class hiking_reputation
{
std::string application_;
std::vector<hiking_reputon> reputons_;
public:
hiking_reputation(const std::string& application,
const std::vector<hiking_reputon>& reputons)
: application_(application),
reputons_(reputons)
{}
const std::string& application() const { return application_;}
const std::vector<hiking_reputon>& reputons() const { return reputons_;}
};
} // namespace ns
// Declare the traits using convenience macros. Specify which data members need to be serialized.
JSONCONS_ENUM_TRAITS_DECL(ns::hiking_experience, beginner, intermediate, advanced)
JSONCONS_ALL_CTOR_GETTER_TRAITS(ns::hiking_reputon, rater, assertion, rated, rating)
JSONCONS_ALL_CTOR_GETTER_TRAITS(ns::hiking_reputation, application, reputons)
using namespace jsoncons; // for convenience
int main()
{
std::string data = R"(
{
"application": "hiking",
"reputons": [
{
"rater": "HikingAsylum",
"assertion": "advanced",
"rated": "Marilyn C",
"rating": 0.90
}
]
}
)";
// Decode the string of data into a c++ structure
ns::hiking_reputation v = decode_json<ns::hiking_reputation>(data);
// Iterate over reputons array value
std::cout << "(1)\n";
for (const auto& item : v.reputons())
{
std::cout << item.rated() << ", " << item.rating() << "\n";
}
// Encode the c++ structure into a string
std::string s;
encode_json<ns::hiking_reputation>(v, s, indenting::indent);
std::cout << "(2)\n";
std::cout << s << "\n";
}
Output:
(1)
Marilyn C, 0.9
(2)
{
"application": "hiking",
"reputons": [
{
"assertion": "advanced",
"rated": "Marilyn C",
"rater": "HikingAsylum",
"rating": 0.9
}
]
}
What allowed me to fix the problem was going to: Project -> Properties -> C/C++ General -> Preprocessor Include Paths, Macros, etc. -> Providers -> CDT GCC built-in compiler settings, enabling that and disabling the CDT Cross GCC Built-in Compiler Settings

You have to store the content as a fact:
- set_fact:

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.
If you have accidentally removed DLL file from php/ext
folder, just add it back (get the copy from XAMPP zip archive - its downloadable).
If you have deleted the accompanying INI configuration line from php.ini
file, add it back as well:
extension=php_mbstring.dll
Also, ensure to restart your webserver (Apache) using XAMPP control panel.
Additional Info on Enabling PHP Extensions
/XAMPP/php/ext
directory)extension_dir = "ext"
)If you are using Jenkins templates you could have additional VM settings defined in it and this might conflicting with your system VM settings
example your tempalate may have references such as these
<mavenOpts>-Xms512m -Xmx1024m -Xss1024k -XX:MaxPermSize=1024m -Dmaven.test.failure.ignore=false</mavenOpts>
Ensure to align these template entries with the VM setting of your system
For me, the problem was twofold: First, the version of IIS I was dealing with didn't know about the .woff2
MIME type, only about .woff
. I fixed that using IIS Manager at the server level, not at the web app level, so the setting wouldn't get overridden with each new app deployment. (Under IIS Manager, I went to MIME types, and added the missing .woff2
, then updated .woff
.)
Second, and more importantly, I was bundling bootstrap.css
along with some other files as "~/bundles/css/site"
. Meanwhile, my font files were in "~/fonts"
. bootstrap.css
looks for the glyphicon fonts in "../fonts"
, which translated to "~/bundles/fonts"
-- wrong path.
In other words, my bundle path was one directory too deep. I renamed it to "~/bundles/siteCss"
, and updated all the references to it that I found in my project. Now bootstrap looked in "~/fonts"
for the glyphicon files, which worked. Problem solved.
Before I fixed the second problem above, none of the glyphicon
font files were loading. The symptom was that all instances of glyphicon
glyphs in the project just showed an empty box. However, this symptom only occurred in the deployed versions of the web app, not on my dev machine. I'm still not sure why that was the case.
Check this code in alert box have edit textview when click OK it displays on screen using toast.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final AlertDialog.Builder alert = new AlertDialog.Builder(this);
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString().trim();
Toast.makeText(getApplicationContext(), value,
Toast.LENGTH_SHORT).show();
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
alert.show();
}
Use this to obtain only the filename.
Path.GetFileName(files[0]);
As paxdiablo said make -f pax.mk
would execute the pax.mk makefile, if you directly execute it by typing ./pax.mk, then you would get syntax error.
Also you can just type make
if your file name is makefile/Makefile
.
Suppose you have two files named makefile
and Makefile
in the same directory then makefile
is executed if make
alone is given. You can even pass arguments to makefile.
Check out more about makefile at this Tutorial : Basic understanding of Makefile
After looking over the W3 spec for text-overflow, I don't think this is possible using only CSS. Ellipsis is a new-ish property, so it probably hasn't received much usage or feedback as of yet.
However, this guy appears to have asked a similar (or identical) question, and someone was able to come up with a nice jQuery solution. You can demo the solution here: http://jsfiddle.net/MPkSF/
If javascript is not an option, I think you may be out of luck...
I added export PATH=${PATH}:/Users/mishrapranjal/android-sdks/platform-tools/
into both places .bash_profile
and .profile
to make sure it works. Still it wasn't working and then I looked at sarnold's tip about restarting terminal and it worked like a charm.
It saved my time of adding every time this into the PATH
whenever I had to run adb
.
Thank you guys.
With Java 8
DateTime
/LocalDateTime
:
String dateString = "01/13/2012";
DateTimeFormatter dateFormat = DateTimeFormatter.ofPattern("MM/dd/yyyy", Locale.US);
LocalDate date = LocalDate.parse(dateString, dateFormat);
ValueRange range = date.range(ChronoField.DAY_OF_MONTH);
Long max = range.getMaximum();
LocalDate newDate = date.withDayOfMonth(max.intValue());
System.out.println(newDate);
OR
String dateString = "01/13/2012";
DateTimeFormatter dateFormat = DateTimeFormatter.ofPattern("MM/dd/yyyy", Locale.US);
LocalDate date = LocalDate.parse(dateString, dateFormat);
LocalDate newDate = date.withDayOfMonth(date.getMonth().length(date.isLeapYear()));
System.out.println(newDate);
Output:
2012-01-31
LocalDateTime
should be used instead ofLocalDate
if you have time information in your date string . I.E.2015/07/22 16:49
Enter some junk value into your .htaccess
e.g. foo bar
, sakjnaskljdnas
any keyword not recognized by htaccess
and visit your URL. If it is working, you should get a
500 Internal Server Error
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request....
I suggest you to put it soon after RewriteEngine on
.
Since you are on your machine. I presume you have access to apache .conf
file.
open the .conf
file, and look for a line similar to:
LoadModule rewrite_module modules/mod_rewrite.so
If it is commented(#), uncomment and restart apache.
To log rewrite
RewriteEngine On
RewriteLog "/path/to/rewrite.log"
RewriteLogLevel 9
Put the above 3 lines in your virtualhost
. restart the httpd.
RewriteLogLevel 9
Using a high value for Level will slow down your Apache server dramatically! Use the rewriting logfile at a Level greater than 2 only for debugging!
Level 9 will log almost every rewritelog detail.
Things have changed in Apache 2.4:
FROM Upgrading to 2.4 from 2.2
The RewriteLog and RewriteLogLevel directives have been removed. This functionality is now provided by configuring the appropriate level of logging for the mod_rewrite module using the LogLevel directive. See also the mod_rewrite logging section.
For more on LogLevel, refer LogLevel Directive
you can accomplish
RewriteLog "/path/to/rewrite.log"
in this manner now
LogLevel debug rewrite_module:debug
Take a look at ?legend
and try this:
legend('topright', names(a)[-1] ,
lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)
You can use boolean indexing
:
df = pd.DataFrame({'Sales':[10,20,30,40,50], 'A':[3,4,7,6,1]})
print (df)
A Sales
0 3 10
1 4 20
2 7 30
3 6 40
4 1 50
s = 30
df1 = df[df['Sales'] >= s]
print (df1)
A Sales
2 7 30
3 6 40
4 1 50
df2 = df[df['Sales'] < s]
print (df2)
A Sales
0 3 10
1 4 20
It's also possible to invert mask
by ~
:
mask = df['Sales'] >= s
df1 = df[mask]
df2 = df[~mask]
print (df1)
A Sales
2 7 30
3 6 40
4 1 50
print (df2)
A Sales
0 3 10
1 4 20
print (mask)
0 False
1 False
2 True
3 True
4 True
Name: Sales, dtype: bool
print (~mask)
0 True
1 True
2 False
3 False
4 False
Name: Sales, dtype: bool
I use some css like this (based on css tricks):
@media screen and (min-width: 320px) and (max-width: 767px) and (orientation: portrait) {
html {
transform: rotate(-90deg);
transform-origin: left top;
width: 100vh;
height: 100vw;
overflow-x: hidden;
position: absolute;
top: 100%;
left: 0;
}
}
This is what worked for me, adapted from Adding HTTP Headers to WCF Calls
// Message inspector used to add the User-Agent HTTP Header to the WCF calls for Server
public class AddUserAgentClientMessageInspector : IClientMessageInspector
{
public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, IClientChannel channel)
{
HttpRequestMessageProperty property = new HttpRequestMessageProperty();
var userAgent = "MyUserAgent/1.0.0.0";
if (request.Properties.Count == 0 || request.Properties[HttpRequestMessageProperty.Name] == null)
{
var property = new HttpRequestMessageProperty();
property.Headers["User-Agent"] = userAgent;
request.Properties.Add(HttpRequestMessageProperty.Name, property);
}
else
{
((HttpRequestMessageProperty)request.Properties[HttpRequestMessageProperty.Name]).Headers["User-Agent"] = userAgent;
}
return null;
}
public void AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
{
}
}
// Endpoint behavior used to add the User-Agent HTTP Header to WCF calls for Server
public class AddUserAgentEndpointBehavior : IEndpointBehavior
{
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.MessageInspectors.Add(new AddUserAgentClientMessageInspector());
}
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
}
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
}
public void Validate(ServiceEndpoint endpoint)
{
}
}
After declaring these classes you can add the new behavior to your WCF client like this:
client.Endpoint.Behaviors.Add(new AddUserAgentEndpointBehavior());
Just do this:
// ****** Every first letter capital in word *********
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textCapWords"
/>
//***** if all letters are capital ************
android:inputType="textCapCharacters"
To prevent this dialog box from appearing, do the following:
the solution to your problem looks like this:
public class Category {
public long CategoryId { get; set; }
public string CategoryName { get; set; }
}
...
public class CategoryEqualityComparer : IEqualityComparer<Category>
{
public bool Equals(Category x, Category y)
=> x.CategoryId.Equals(y.CategoryId)
&& x.CategoryName .Equals(y.CategoryName,
StringComparison.OrdinalIgnoreCase);
public int GetHashCode(Mapping obj)
=> obj == null
? 0
: obj.CategoryId.GetHashCode()
^ obj.CategoryName.GetHashCode();
}
...
var distinctCategories = product
.Select(_ =>
new Category {
CategoryId = _.CategoryId,
CategoryName = _.CategoryName
})
.Distinct(new CategoryEqualityComparer())
.ToList();
gcc and g ++ are both GNU compiler. They both compile c and c++. The difference is for *.c files gcc treats it as a c program, and g++ sees it as a c ++ program. *.cpp files are considered to be c ++ programs. c++ is a super set of c and the syntax is more strict, so be careful about the suffix.
From my perspective it is more semantic to use <hr>
elements as line breaks between flex items.
.container {_x000D_
display: flex;_x000D_
flex-flow: wrap;_x000D_
}_x000D_
_x000D_
.container hr {_x000D_
width: 100%;_x000D_
}
_x000D_
<div class="container">_x000D_
<div>1</div>_x000D_
<div>2</div>_x000D_
<hr>_x000D_
<div>3</div>_x000D_
<div>2</div>_x000D_
..._x000D_
</div>
_x000D_
Tested in Chrome 66, Firefox 60 and Safari 11.
Function inside function: we can use the function as parameter too..
In other words, we can say an output of a function is also a reference for an object, see below how the output of inner function is referencing to the outside function like below..
def out_func(a):
def in_func(b):
print(a + b + b + 3)
return in_func
obj = out_func(1)
print(obj(5))

Hope this helps.
With pandas it can be done as:
If lakes is your DataFrame:
area_dict = lakes.to_dict('records')
If your tiles are not in your bundle, either copied from the bundle or downloaded from the internet you can get the directory like this
NSString *documentdir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *tileDirectory = [documentdir stringByAppendingPathComponent:@"xxxx/Tiles"];
NSLog(@"Tile Directory: %@", tileDirectory);
The following is what I use to commit changes on foo
to N=1
days in the past:
git add foo
git commit -m "Update foo"
git commit --amend --date="$(date -v-1d)"
If you want to commit to a even older date, say 3 days back, just change the date
argument: date -v-3d
.
That's really useful when you forget to commit something yesterday, for instance.
UPDATE: --date
also accepts expressions like --date "3 days ago"
or even --date "yesterday"
. So we can reduce it to one line command:
git add foo ; git commit --date "yesterday" -m "Update"
CreateOrReplaceTempView will create a temporary view of the table on memory it is not presistant at this moment but you can run sql query on top of that . if you want to save it you can either persist or use saveAsTable to save.
first we read data in csv format and then convert to data frame and create a temp view
Reading data in csv format
val data = spark.read.format("csv").option("header","true").option("inferSchema","true").load("FileStore/tables/pzufk5ib1500654887654/campaign.csv")
printing the schema
data.printSchema
data.createOrReplaceTempView("Data")
Now we can run sql queries on top the table view we just created
%sql select Week as Date,Campaign Type,Engagements,Country from Data order by Date asc
I suggest you to look at this highly rated blog post which manages to give a solution to the problem you're facing :
http://www.inter-fuser.com/2009/09/live-camera-preview-in-android-emulator.html
His code is based on the current Android APIs and should work in your case given that you are using a recent Android API.
Yes, orWhereIn
is a method that you can use.
I'm fairly sure it should give you the result you're looking for, however, if it doesn't you could simply use implode
to create a string and then explode it (this is a guess at your array structure):
$values = implode(',', array_map(function($value)
{
return trim($value, ',');
}, $filters));
$query->whereIn('products.value', explode(',' $values));
You can also try this for the double quotes:
JSON.stringify(sDemoString).slice(1, -1);
JSON.stringify('my string with "quotes"').slice(1, -1);
If you have multiple subplots, i.e.
fig, ax = plt.subplots(4, 2)
You can use the same y limits for all of them. It gets limits of y ax from first plot.
plt.setp(ax, ylim=ax[0,0].get_ylim())
Here is a dplyr
based option:
newV = df %>% slice(1) %>% unlist(use.names = FALSE)
# or slightly different:
newV = df %>% slice(1) %>% unlist() %>% unname()
OO Abstraction occurs during class level design, with the objective of hiding the implementation complexity of how the the features offered by an API / design / system were implemented, in a sense simplifying the 'interface' to access the underlying implementation.
The process of abstraction can be repeated at increasingly 'higher' levels (layers) of classes, which enables large systems to be built without increasing the complexity of code and understanding at each layer.
For example, a Java developer can make use of the high level features of FileInputStream without concern for how it works (i.e. file handles, file system security checks, memory allocation and buffering will be managed internally, and are hidden from consumers). This allows the implementation of FileInputStream
to be changed, and as long as the API (interface) to FileInputStream
remains consistent, code built against previous versions will still work.
Similarly, when designing your own classes, you will want to hide internal implementation details from others as far as possible.
In the Booch definition1, OO Encapsulation is achieved through Information Hiding, and specifically around hiding internal data (fields / members representing the state) owned by a class instance, by enforcing access to the internal data in a controlled manner, and preventing direct, external change to these fields, as well as hiding any internal implementation methods of the class (e.g. by making them private).
For example, the fields of a class can be made private
by default, and only if external access to these was required, would a get()
and/or set()
(or Property
) be exposed from the class. (In modern day OO languages, fields can be marked as readonly
/ final
/ immutable
which further restricts change, even within the class).
Example where NO information hiding has been applied (Bad Practice):
class Foo {
// BAD - NOT Encapsulated - code external to the class can change this field directly
// Class Foo has no control over the range of values which could be set.
public int notEncapsulated;
}
Example where field encapsulation has been applied:
class Bar {
// Improvement - access restricted only to this class
private int encapsulatedPercentageField;
// The state of Bar (and its fields) can now be changed in a controlled manner
public void setEncapsulatedField(int percentageValue) {
if (percentageValue >= 0 && percentageValue <= 100) {
encapsulatedPercentageField = percentageValue;
}
// else throw ... out of range
}
}
Example of immutable / constructor-only initialization of a field:
class Baz {
private final int immutableField;
public void Baz(int onlyValue) {
// ... As above, can also check that onlyValue is valid
immutableField = onlyValue;
}
// Further change of `immutableField` outside of the constructor is NOT permitted, even within the same class
}
Re : Abstraction vs Abstract Class
Abstract classes are classes which promote reuse of commonality between classes, but which themselves cannot directly be instantiated with new()
- abstract classes must be subclassed, and only concrete
(non abstract) subclasses may be instantiated. Possibly one source of confusion between Abstraction
and an abstract class
was that in the early days of OO, inheritance was more heavily used to achieve code reuse (e.g. with associated abstract base classes). Nowadays, composition is generally favoured over inheritance, and there are more tools available to achieve abstraction, such as through Interfaces, events / delegates / functions, traits / mixins etc.
Re : Encapsulation vs Information Hiding
The meaning of encapsulation appears to have evolved over time, and in recent times, encapsulation
can commonly also used in a more general sense when determining which methods, fields, properties, events etc to bundle into a class.
Quoting Wikipedia:
In the more concrete setting of an object-oriented programming language, the notion is used to mean either an information hiding mechanism, a bundling mechanism, or the combination of the two.
For example, in the statement
I've encapsulated the data access code into its own class
.. the interpretation of encapsulation is roughly equivalent to the Separation of Concerns or the Single Responsibility Principal (the "S" in SOLID), and could arguably be used as a synonym for refactoring.
[1] Once you've seen Booch's encapsulation cat picture you'll never be able to forget encapsulation - p46 of Object Oriented Analysis and Design with Applications, 2nd Ed
No need for moment.js to parse the input since its format is the standard one :
var date = new Date('2014-02-27T10:00:00');
var formatted = moment(date).format('D MMMM YYYY');
Your best bet is to set disabled=true on the option items you want to disable, then in CSS set
option:disabled {
display: none;
}
That way even if the browser doesn't support hiding the disabled item, it still can't be selected.. but on browsers that do support it, they will be hidden.
Update on the accepted answer:
Because of many properties becoming deprecated
(property) KeyboardEvent.which: number @deprecated
you should just rely on the key property and create the rest of the logic by yourself:
The code allows Enter, Backspace and all numbers [0-9], every other character is disallowed.
document.querySelector("input").addEventListener("keypress", (e) => {
if (isNaN(parseInt(e.key, 10)) && e.key !== "Backspace" && e.key !== "Enter") {
e.preventDefault();
}
});
NOTE This will disable paste action
NSString *valueToSave = @"someValue";
[[NSUserDefaults standardUserDefaults] setObject:valueToSave forKey:@"preferenceName"];
[[NSUserDefaults standardUserDefaults] synchronize];
to get it back later
NSString *savedValue = [[NSUserDefaults standardUserDefaults]
stringForKey:@"preferenceName"];
In your codethis
refers to the select element not to the selected option
to refer the selected option you can do this -
$(this).find('option:selected').attr("name");
Be careful if you have spaces in your string variables and you check for existence. Be sure to quote them properly.
if [ ! "${somepath}" ] || [ ! "${otherstring}" ] || [ ! "${barstring}" ] ; then
You could even try this expression ^[a-zA-Z\\s]*$
for checking a string with only letters and spaces (nothing else).
For me it worked. Hope it works for you as well.
Or go through this piece of code once:
CharSequence inputStr = expression;
Pattern pattern = Pattern.compile(new String ("^[a-zA-Z\\s]*$"));
Matcher matcher = pattern.matcher(inputStr);
if(matcher.matches())
{
//if pattern matches
}
else
{
//if pattern does not matches
}
My function takes into account factor, character vector and potential attributes, if you use haven or foreign package to read external files. Also it allows matching different self-defined na.strings. To transform all columns, simply use lappy: df[] = lapply(df, blank2na, na.strings=c('','NA','na','N/A','n/a','NaN','nan'))

This option was introduced in order to remove the need to deploy very large PIAs (Primary Interop Assemblies) for interop.
It simply embeds the managed bridging code used that allows you to talk to unmanaged assemblies, but instead of embedding it all it only creates the stuff you actually use in code.
Read more in Scott Hanselman's blog post about it and other VS improvements here.
As for whether it is advised or not, I'm not sure as I don't need to use this feature. A quick web search yields a few leads:
The only risk of turning them all to false is more deployment concerns with PIA files and a larger deployment if some of those files are large.
It's not an issue related to authentication at the first step. Your import
is not working. So, try writing this on first line:
#!/usr/bin/python
and for the time being run using
python xx.py
For you here is one explanation:
>>> abc = "Hei Buddy"
>>> print "%s" %abc
Hei Buddy
>>>
>>> print "%s" %xyz
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
print "%s" %xyz
NameError: name 'xyz' is not defined
At first, I initialized abc variable and it works fine. On the otherhand, xyz doesn't work as it is not initialized!
The code creates an anonymous function, and then immediately runs it. Similar to:
var temp = function() {
// init part
}
temp();
The purpose of this construction is to create a scope for the code inside the function. You can declare varaibles and functions inside the scope, and those will be local to that scope. That way they don't clutter up the global scope, which minimizes the risk for conflicts with other scripts.
A variable cannot be both null
and undefined
at the same time. However, the direct answer to your question is:
if (variable != null)
One =
, not two.
There are two special clauses in the "abstract equality comparison algorithm" in the JavaScript spec devoted to the case of one operand being null
and the other being undefined
, and the result is true
for ==
and false
for !=
. Thus if the value of the variable is undefined
, it's not != null
, and if it's not null, it's obviously not != null
.
Now, the case of an identifier not being defined at all, either as a var
or let
, as a function parameter, or as a property of the global context is different. A reference to such an identifier is treated as an error at runtime. You could attempt a reference and catch the error:
var isDefined = false;
try {
(variable);
isDefined = true;
}
catch (x) {}
I would personally consider that a questionable practice however. For global symbols that may or may be there based on the presence or absence of some other library, or some similar situation, you can test for a window
property (in browser JavaScript):
var isJqueryAvailable = window.jQuery != null;
or
var isJqueryAvailable = "jQuery" in window;
From ioS 7 onwards, there are newer ways for apps to run in background. Apple now recognizes that apps have to constantly download and process data constantly.
- Apps that play audible content to the user while in the background, such as a music player app
- Apps that record audio content while in the background.
- Apps that keep users informed of their location at all times, such as a navigation app
- Apps that support Voice over Internet Protocol (VoIP)
- Apps that need to download and process new content regularly
- Apps that receive regular updates from external accessories
You can declare app's supported background tasks in Info.plist using X Code 5+. For eg. adding UIBackgroundModes key to your app’s Info.plist file and adding a value of 'fetch' to the array allows your app to regularly download and processes small amounts of content from the network. You can do the same in the 'capabilities' tab of Application properties in XCode 5 (attaching a snapshot)
You can find more about this in Apple documentation
Some color-syntaxing enrichment can be applied with the following blockcode syntax

Just a note in case others have the same problem.
I had the same problem and found a different answer. I found that getting the height of a div that's height is determined by its contents needs to be initiated on window.load, or window.scroll not document.ready otherwise i get odd heights/smaller heights, i.e before the images have loaded. I also used outerHeight().
var currentHeight = 0;
$(window).load(function() {
//get the natural page height -set it in variable above.
currentHeight = $('#js_content_container').outerHeight();
console.log("set current height on load = " + currentHeight)
console.log("content height function (should be 374) = " + contentHeight());
});
You can sort a list in-place just by calling List<T>.Sort
:
list.Sort();
That will use the natural ordering of elements, which is fine in your case.
EDIT: Note that in your code, you'd need
_details.Sort();
as the Sort
method is only defined in List<T>
, not IList<T>
. If you need to sort it from the outside where you don't have access to it as a List<T>
(you shouldn't cast it as the List<T>
part is an implementation detail) you'll need to do a bit more work.
I don't know of any IList<T>
-based in-place sorts in .NET, which is slightly odd now I come to think of it. IList<T>
provides everything you'd need, so it could be written as an extension method. There are lots of quicksort implementations around if you want to use one of those.
If you don't care about a bit of inefficiency, you could always use:
public void Sort<T>(IList<T> list)
{
List<T> tmp = new List<T>(list);
tmp.Sort();
for (int i = 0; i < tmp.Count; i++)
{
list[i] = tmp[i];
}
}
In other words, copy, sort in place, then copy the sorted list back.
You can use LINQ to create a new list which contains the original values but sorted:
var sortedList = list.OrderBy(x => x).ToList();
It depends which behaviour you want. Note that your shuffle method isn't really ideal:
Random
within the method runs into some of the problems shown hereval
inside the loop - you're not using that default valueCount
property when you know you're working with an IList<T>
for
loop is simpler to understand than traversing the list backwards with a while
loopThere are other implementations of shuffling with Fisher-Yates on Stack Overflow - search and you'll find one pretty quickly.
In addition to the above, you can do this (where "YourListObjectName" is the name of your table):
Dim LO As ListObject
Set LO = ActiveSheet.ListObjects("YourListObjectName")
But I think that only works if you want to reference a list object that's on the active sheet.
I found your question because I wanted to refer to a list object (a table) on one worksheet that a pivot table on a different worksheet refers to. Since list objects are part of the Worksheets collection, you have to know the name of the worksheet that list object is on in order to refer to it. So to get the name of the worksheet that the list object is on, I got the name of the pivot table's source list object (again, a table) and looped through the worksheets and their list objects until I found the worksheet that contained the list object I was looking for.
Public Sub GetListObjectWorksheet()
' Get the name of the worksheet that contains the data
' that is the pivot table's source data.
Dim WB As Workbook
Set WB = ActiveWorkbook
' Create a PivotTable object and set it to be
' the pivot table in the active cell:
Dim PT As PivotTable
Set PT = ActiveCell.PivotTable
Dim LO As ListObject
Dim LOWS As Worksheet
' Loop through the worksheets and each worksheet's list objects
' to find the name of the worksheet that contains the list object
' that the pivot table uses as its source data:
Dim WS As Worksheet
For Each WS In WB.Worksheets
' Loop through the ListObjects in each workshet:
For Each LO In WS.ListObjects
' If the ListObject's name is the name of the pivot table's soure data,
' set the LOWS to be the worksheet that contains the list object:
If LO.Name = PT.SourceData Then
Set LOWS = WB.Worksheets(LO.Parent.Name)
End If
Next LO
Next WS
Debug.Print LOWS.Name
End Sub
Maybe someone knows a more direct way.
I added the following method to my PageBase class.

{
Response.Redirect(url);
}

if (querystrings != null)
{
for (int index = 0; index < querystrings.Count; index++)
{
if (index == 0)
{
redirectUrl.Append("?");
}
redirectUrl.Append(querystrings.Keys[index]);
redirectUrl.Append("=");
redirectUrl.Append(HttpUtility.UrlEncode(querystrings[index]));
if (index < querystrings.Count - 1)
{
redirectUrl.Append("&");
}
}
}
this.Redirect(redirectUrl.ToString());

NameValueCollection querystrings = new NameValueCollection();
querystrings.Add("language", "en");
querystrings.Add("id", "134");

If you're using Eclipse

Those are two different things, as others have mentioned.
When you specify # -*- coding: utf-8 -*-
, you're telling Python the source file you've saved is utf-8
. The default for Python 2 is ASCII (for Python 3 it's utf-8
). This just affects how the interpreter reads the characters in the file.
In general, it's probably not the best idea to embed high unicode characters into your file no matter what the encoding is; you can use string unicode escapes, which work in either encoding.
When you declare a string with a u
in front, like u'This is a string'
, it tells the Python compiler that the string is Unicode, not bytes. This is handled mostly transparently by the interpreter; the most obvious difference is that you can now embed unicode characters in the string (that is, u'\u2665'
is now legal). You can use from __future__ import unicode_literals
to make it the default.
This only applies to Python 2; in Python 3 the default is Unicode, and you need to specify a b
in front (like b'These are bytes'
, to declare a sequence of bytes).
You could also do something as follow
public enum DAY {MON, TUES, WED, THU, FRI, SAT, SUN};
EnumSet.allOf(DAY.class).stream().map(e -> e.name()).collect(Collectors.toList())
or
EnumSet.allOf(DAY.class).stream().map(DAY::name).collect(Collectors.toList())
The main reason why I stumbled across this question is that I wanted to write a generic validator that validates whether a given string enum name is valid for a given enum type (Sharing in case anyone finds useful).
For the validation, I had to use Apache's EnumUtils
library since the type of enum is not known at compile time.
@SuppressWarnings({ "unchecked", "rawtypes" })
public static void isValidEnumsValid(Class clazz, Set<String> enumNames) {
Set<String> notAllowedNames = enumNames.stream()
.filter(enumName -> !EnumUtils.isValidEnum(clazz, enumName))
.collect(Collectors.toSet());
if (notAllowedNames.size() > 0) {
String validEnumNames = (String) EnumUtils.getEnumMap(clazz).keySet().stream()
.collect(Collectors.joining(", "));
throw new IllegalArgumentException("The requested values '" + notAllowedNames.stream()
.collect(Collectors.joining(",")) + "' are not valid. Please select one more (case-sensitive) "
+ "of the following : " + validEnumNames);
}
}
I was too lazy to write an enum annotation validator as shown in here https://stackoverflow.com/a/51109419/1225551

Just create random number for notification_id.
Random random = new Random();
int m = random.nextInt(9999 - 1000) + 1000;
or you can use this method for creating random number as told by tieorange (this will never get repeated):
int m = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
and replace this line to add parameter for notification id as to generate random number
notificationManager.notify(m, notification);

Give unique class and different id for file input
$("#tab-content").on('change',class,function()
{
var id=$(this).attr('id');
$("#"+id).trigger(your function);
//for name of file input $("#"+id).attr("name");
});
This is how I would do it (assuming I understand the question)
SELECT * FROM pieces ORDER BY price ASC LIMIT 1
If you are trying to select multiple rows where each of them may have the same price (which is the minimum) then @JohnWoo's answer should suffice.
Basically here we are just ordering the results by the price in ASCending order (increasing) and taking the first row of the result.
You should avoid using pool.getConnection()
if you can. If you call pool.getConnection()
, you must call connection.release()
when you are done using the connection. Otherwise, your application will get stuck waiting forever for connections to be returned to the pool once you hit the connection limit.
For simple queries, you can use pool.query()
. This shorthand will automatically call connection.release()
for you—even in error conditions.
function doSomething(cb) {
pool.query('SELECT 2*2 "value"', (ex, rows) => {
if (ex) {
cb(ex);
} else {
cb(null, rows[0].value);
}
});
}
However, in some cases you must use pool.getConnection()
. These cases include:
If you must use pool.getConnection()
, ensure you call connection.release()
using a pattern similar to below:
function doSomething(cb) {
pool.getConnection((ex, connection) => {
if (ex) {
cb(ex);
} else {
// Ensure that any call to cb releases the connection
// by wrapping it.
cb = (cb => {
return function () {
connection.release();
cb.apply(this, arguments);
};
})(cb);
connection.beginTransaction(ex => {
if (ex) {
cb(ex);
} else {
connection.query('INSERT INTO table1 ("value") VALUES (\'my value\');', ex => {
if (ex) {
cb(ex);
} else {
connection.query('INSERT INTO table2 ("value") VALUES (\'my other value\')', ex => {
if (ex) {
cb(ex);
} else {
connection.commit(ex => {
cb(ex);
});
}
});
}
});
}
});
}
});
}
I personally prefer to use Promise
s and the useAsync()
pattern. This pattern combined with async
/await
makes it a lot harder to accidentally forget to release()
the connection because it turns your lexical scoping into an automatic call to .release()
:
async function usePooledConnectionAsync(actionAsync) {
const connection = await new Promise((resolve, reject) => {
pool.getConnection((ex, connection) => {
if (ex) {
reject(ex);
} else {
resolve(connection);
}
});
});
try {
return await actionAsync(connection);
} finally {
connection.release();
}
}
async function doSomethingElse() {
// Usage example:
const result = await usePooledConnectionAsync(async connection => {
const rows = await new Promise((resolve, reject) => {
connection.query('SELECT 2*4 "value"', (ex, rows) => {
if (ex) {
reject(ex);
} else {
resolve(rows);
}
});
});
return rows[0].value;
});
console.log(`result=${result}`);
}
Thanks to @Dirk Lachowski for pointing me in the right direction. The solution isn't as elegant as I would have liked, but I got it working. Reading the spring docs, I can listen on the EmbeddedServletContainerInitializedEvent and get the port once the server is up and running. Here's what it looks like -
import org.springframework.boot.context.embedded.EmbeddedServletContainerInitializedEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;
@Component
public class MyListener implements ApplicationListener<EmbeddedServletContainerInitializedEvent> {
@Override
public void onApplicationEvent(final EmbeddedServletContainerInitializedEvent event) {
int thePort = event.getEmbeddedServletContainer().getPort();
}
}

To do this with multiple images you need to run though an .each()
function. This works but I'm not sure how efficient it is.
$('img').hide();
$('img').each( function(){
$(this).on('load', function () {
$(this).fadeIn();
});
});
Since PyCharm 3.4 the path tab in the 'Project Interpreter' settings has been replaced. In order to add paths to a project you need to select the cogwheel, click on 'More...' and then select the "Show path for the selected interpreter" icon. This allows you to add paths to your project as before.
My project is now behaving as I would expect.
I often use a quick-n-dirty trick to read a fixed number of arguments from the command-line:
[filename] = sys.argv[1:]
in_file = open(filename) # Don't need the "r"
This will assign the one argument to filename
and raise an exception if there isn't exactly one argument.
You have to give a name
attribute on your <select />
element, and then use it from the $_POST
or $_GET
(depending on how you transmit data) arrays in PHP. Be sure to sanitize user input, though.
use global scope on your $con and put it inside your getPosts() function like so.
function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
{
echo "<div class=\"blogsnippet\">";
echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
echo "</div>";
}
}
When you run
install.packages("whatever")
you got message that your binaries are downloaded into temporary location (e.g. The downloaded binary packages are in C:\Users\User_name\AppData\Local\Temp\RtmpC6Y8Yv\downloaded_packages ). Go there. Take binaries (zip file). Copy paste into location which you get from running the code:
.libPaths()
If libPaths shows 2 locations, then paste into second one. Load library:
library(whatever)
Fixed.
You can use google map Obtaining User Location here!
After obtaining your location(longitude and latitude), you can use google place api
This code can help you get your location easily but not the best way.
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
String bestProvider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(bestProvider);

Left padding String
extension similar to padding(toLength:withPad:startingAt:)
in Foundation
extension String {
func leftPadding(toLength: Int, withPad: String = " ") -> String {
guard toLength > self.characters.count else { return self }
let padding = String(repeating: withPad, count: toLength - self.characters.count)
return padding + self
}
}
Usage:
let s = String(123)
s.leftPadding(toLength: 8, withPad: "0") // "00000123"
If the application is running in the foreground, iOS won't show a notification banner/alert. That's by design. You have to write some code to deal with the situation of your app receiving a notification while it is in the foreground. You should show the notification in the most appropriate way (for example, adding a badge number to a UITabBar
icon, simulating a Notification Center banner, etc.).
You can use setdiff
.
Given
a <- sample(1:10)
remove <- c(2, 3, 5)
Then
> a
[1] 10 8 9 1 3 4 6 7 2 5
> setdiff(a, remove)
[1] 10 8 9 1 4 6 7
If you are using Vue JS, just append @mousedown.prevent=""

In medicine there are four genders: male, female, indeterminate, and unknown. You mightn't need all four but you certainly need 1, 2, and 4. It's not appropriate to have a default value for this datatype. Even less to treat it as a Boolean with 'is' and 'isn't' states.
Try ContentTemplate:

If you are looking for the contents of the TD (cell), then it would simply be: col.innerHTML
I.e: alert(col.innerHTML);
You'll then need to parse that for any values you're looking for.
Try applying the clear:none
css attribute to the label.
.label {
clear:none;
}
I had the same problem with Spring Boot, Spring Cloud (microservices) and a self-signed SSL certificate. Keystore worked out of the box from application properties, and Truststore didn't.
I ended up keeping both keystore and trustore configuration in application.properties, and adding a separate configuration bean for configuring truststore properties with the System.
@Configuration
public class SSLConfig {
@Autowired
private Environment env;
@PostConstruct
private void configureSSL() {
//set to TLSv1.1 or TLSv1.2
System.setProperty("https.protocols", "TLSv1.1");
//load the 'javax.net.ssl.trustStore' and
//'javax.net.ssl.trustStorePassword' from application.properties
System.setProperty("javax.net.ssl.trustStore", env.getProperty("server.ssl.trust-store"));
System.setProperty("javax.net.ssl.trustStorePassword",env.getProperty("server.ssl.trust-store-password"));
}
}
I think it is the domain that you run your app.
For example, your canvas URL is facebook.yourdomain.com, you should give App domain as .yourdomain.com
Use this code where str is your JSON string:
NSError *err = nil;
NSArray *arr =
[NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding]
options:NSJSONReadingMutableContainers
error:&err];
// access the dictionaries
NSMutableDictionary *dict = arr[0];
for (NSMutableDictionary *dictionary in arr) {
// do something using dictionary
}
slf4j is only an API. You should have a concrete implementation (for example log4j). This concrete implementation has a config file which tells you where to store the logs.
When slf4j catches a log messages with a logger, it is given to an appender which decides what to do with the message. By default, the ConsoleAppender displays the message in the console.
The default configuration file is :
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<!-- By default => console -->
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
If you put a configuration file available in the classpath, then your concrete implementation (in your case, log4j) will find and use it. See Log4J documentation.
Example of file appender :
<Appenders>
<File name="File" fileName="${filename}">
<PatternLayout>
<pattern>%d %p %C{1.} [%t] %m%n</pattern>
</PatternLayout>
</File>
...
</Appenders>
Complete example with a file appender :
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<File name="File" fileName="${filename}">
<PatternLayout>
<pattern>%d %p %C{1.} [%t] %m%n</pattern>
</PatternLayout>
</File>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="File"/>
</Root>
</Loggers>
</Configuration>
You can't do it. Interfaces don't exist at runtime (like @basarat said).
Now, I am working with following:
const IMyTable_id = 'id';
const IMyTable_title = 'title';
const IMyTable_createdAt = 'createdAt';
const IMyTable_isDeleted = 'isDeleted';
export const IMyTable_keys = [
IMyTable_id,
IMyTable_title,
IMyTable_createdAt,
IMyTable_isDeleted,
];
export interface IMyTable {
[IMyTable_id]: number;
[IMyTable_title]: string;
[IMyTable_createdAt]: Date;
[IMyTable_isDeleted]: boolean;
}
This article sums it up pretty well
Summary: It's implementation dependent, as there is no specified limit in the RFC. It'd be safe to use up to 2000 characters (IE's limit.) If you are anywhere near this length, you should make sure you really need URIs that long, maybe an alternative design could get around that.
URIs should be readable, even when used to send data.
The database I did most of my work on used 'Y' / 'N' as booleans. With that implementation, you can pull off some tricks like:
Count rows that are true:
SELECT SUM(CASE WHEN BOOLEAN_FLAG = 'Y' THEN 1 ELSE 0) FROM X
When grouping rows, enforce "If one row is true, then all are true" logic:
SELECT MAX(BOOLEAN_FLAG) FROM Y
Conversely, use MIN to force the grouping false if one row is false.
I found that the accepted answer's solution unfortunately does not compile on Swift 3 for Linux. Here's a modified version, then, that does:
import Foundation
func matches(for regex: String, in text: String) -> [String] {
do {
let regex = try RegularExpression(pattern: regex, options: [])
let nsString = NSString(string: text)
let results = regex.matches(in: text, options: [], range: NSRange(location: 0, length: nsString.length))
return results.map { nsString.substring(with: $0.range) }
} catch let error {
print("invalid regex: \(error.localizedDescription)")
return []
}
}
The main differences are:
Swift on Linux seems to require dropping the NS
prefix on Foundation objects for which there is no Swift-native equivalent. (See Swift evolution proposal #86.)
Swift on Linux also requires specifying the options
arguments for both the RegularExpression
initialization and the matches
method.
For some reason, coercing a String
into an NSString
doesn't work in Swift on Linux but initializing a new NSString
with a String
as the source does work.
This version also works with Swift 3 on macOS / Xcode with the sole exception that you must use the name NSRegularExpression
instead of RegularExpression
.

Like JeanT's answer, I wanted an abstraction around adding to the path. Unlike JeanT's answer I needed it to run without user interaction. Other behavior I was looking for:
$env:Path
so the change takes effect in the current sessionIn case it's useful, here it is:
function Add-EnvPath {
param(
[Parameter(Mandatory=$true)]
[string] $Path,
[ValidateSet('Machine', 'User', 'Session')]
[string] $Container = 'Session'
)
if ($Container -ne 'Session') {
$containerMapping = @{
Machine = [EnvironmentVariableTarget]::Machine
User = [EnvironmentVariableTarget]::User
}
$containerType = $containerMapping[$Container]
$persistedPaths = [Environment]::GetEnvironmentVariable('Path', $containerType) -split ';'
if ($persistedPaths -notcontains $Path) {
$persistedPaths = $persistedPaths + $Path | where { $_ }
[Environment]::SetEnvironmentVariable('Path', $persistedPaths -join ';', $containerType)
}
}
$envPaths = $env:Path -split ';'
if ($envPaths -notcontains $Path) {
$envPaths = $envPaths + $Path | where { $_ }
$env:Path = $envPaths -join ';'
}
}
Check out my gist for the corresponding Remove-EnvPath
function.
I know that due to this ugly anonymous inner class usage of TransactionTemplate
doesn't look nice, but when for some reason we want to have a test method transactional IMHO it is the most flexible option.
In some cases (it depends on the application type) the best way to use transactions in Spring tests is a turned-off @Transactional
on the test methods. Why? Because @Transactional
may leads to many false-positive tests. You may look at this sample article to find out details. In such cases TransactionTemplate
can be perfect for controlling transaction boundries when we want that control.
If you are using lodash, you could use their "has" function. It is similar to the native "in", but allows paths.
var testObject = {a: {b: {c: 'walrus'}}};
if(_.has(testObject, 'a.b.c')) {
//Safely access your walrus here
}
There is more than one way to do this.
Here is a good resource straight from Google: http://developer.android.com/training/basics/firstapp/starting-activity.html
At developer.android.com, they have numerous tutorials explaining just about everything you need to know about android. They even provide detailed API for each class.
If that doesn't help, there are NUMEROUS different resources that can help you with this question and other android questions.
In my case, it was also showing some lock problems whenever my local system shuts down without stopping the MongoDB server.
But it just worked only by using sudo command:-
$ sudo mongod --port 27017
Try to use this with single quotes in data:
insert into table test_hive values ('1','puneet');
Try calling read_csv
with encoding='latin1'
, encoding='iso-8859-1'
or encoding='cp1252'
(these are some of the various encodings found on Windows).
My colleague just found a reference to that method right after I posted (in reference to css) at http://www.stefanhayden.com/blog/2006/04/03/css-caching-hack/. Good to see that others are using it and it seems to work. I assume at this point that there isn't a better way than find-replace to increment these "version numbers" in all of the script tags?
If it's errors you want to hide you can do it like this
$ErrorActionPreference = "SilentlyContinue"; #This will hide errors
$someObject.SomeFunction();
$ErrorActionPreference = "Continue"; #Turning errors back on
Git 1.8.2 features a new option, --remote
, that will enable exactly this behavior. Running
git submodule update --remote --merge
will fetch the latest changes from upstream in each submodule, merge them in, and check out the latest revision of the submodule. As the documentation puts it:
--remote
This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.
This is equivalent to running git pull
in each submodule, which is generally exactly what you want.
Newer versions of datetimepicker (I'm using is use 2.3.7) use format:"Y/m/d"

An upside-down circumflex is called a caron, or a hácek.
It has an HTML entity in the TADS Latin-2 extension to HTML: ˇ

You can use Underscore .filter
var arr = [{
id: 1,
name: 'a'
}, {
id: 2,
name: 'b'
}, {
id: 3,
name: 'c'
}];
var filtered = _(arr).filter(function(item) {
return item.id !== 3
});
Can also be written as:
var filtered = arr.filter(function(item) {
return item.id !== 3
});
var filtered = _.filter(arr, function(item) {
return item.id !== 3
});
You can also use .reject
First of all scipy.misc.imread and PIL are no longer available. Instead use imageio library but you need to install Pillow for that as a dependancy
pip install Pillow imageio
Then use the following code to load the image and get the details about it.
import imageio
import tensorflow as tf
path = 'your_path_to_image' # '~/Downloads/image.png'
img = imageio.imread(path)
print(img.shape)
or
img_tf = tf.Variable(img)
print(img_tf.get_shape().as_list())
both work fine.

As of year 2020, JetBrains suggests to commit the .idea
folder.
The JetBrains IDEs (webstorm, intellij, android studio, pycharm, clion, etc.) automatically add that folder to your git repository (if there's one).
Inside the folder .idea
, has been already created a .gitignore
, updated by the IDE itself to avoid to commit user related settings that may contains privacy/password data.
It is safe (and usually useful) to commit the .idea
folder.
They are different functions. You should decide for your situation what do you need.
I don't consider using any of them as a bad practice. Most of the time IsNullOrEmpty()
is enough. But you have the choice :)
Navigate to the folder on your new machine you want to download from git on git bash.
Use below command to download the code from any branch you like
git clone 'git ssh url' -b 'Branch Name'
It will download the respective branch code.
The centos dockerfile has a default command bash
.
That means, when run in background (-d
), the shell exits immediately.
Update 2017
More recent versions of docker authorize to run a container both in detached mode and in foreground mode (-t
, -i
or -it
)
In that case, you don't need any additional command and this is enough:
docker run -t -d centos
The bash will wait in the background.
That was initially reported in kalyani-chaudhari's answer and detailed in jersey bean's answer.

Note that for alpine, Marinos An reports in the comments:
docker run -t -d alpine/git
does not keep the process up.
Had to do:docker run --entrypoint "/bin/sh" -it alpine/git
Original answer (2015)
As mentioned in this article:
Instead of running with
docker run -i -t image your-command
, using-d
is recommended because you can run your container with just one command and you don’t need to detach terminal of container by hitting Ctrl + P + Q.
However, there is a problem with
-d
option. Your container immediately stops unless the commands keep running in foreground.
Docker requires your command to keep running in the foreground. Otherwise, it thinks that your applications stops and shutdown the container.
The problem is that some application does not run in the foreground. How can we make it easier?
In this situation, you can add
tail -f /dev/null
to your command.
By doing this, even if your main command runs in the background, your container doesn’t stop because tail is keep running in the foreground.
So this would work:
docker run -d centos tail -f /dev/null
A docker ps
would show the centos container still running.
From there, you can attach to it or detach from it (or docker exec
some commands).
You have set #slider
as absolute
, which means that it "is positioned relative to the nearest positioned ancestor" (confusing, right?). Meanwhile, #content
div is placed relative, which means "relative to its normal position". So the position of the 2 divs is not related.
You can read about CSS positioning here
If you set both to relative
, the divs will be one after the other, as shown here:
#slider {
position:relative;
left:0;
height:400px;
border-style:solid;
border-width:5px;
}
#slider img {
width:100%;
}
#content {
position:relative;
}
#content #text {
position:relative;
width:950px;
height:215px;
color:red;
}
Windows doesn't support SSH/SCP/SFTP
natively. Are you running an SSH server application on that Windows server? If so, one of the configuration options is probably where the root is, and you would specify paths relative to that root. In any case, check the documentation for the SSH server application you are running in Windows.
Alternatively, use smbclient
to push the file to a Windows share.
I had the same problem using the AWS Toolkit for Eclipse. I created the Getting Started instance OK and opened a shell. However, the user was set to ec2-user. I used the Open Shell As... command and set the user to root. Then it worked.
There's always the hardware route. Purchase two USB to serial converters, and connect them via a NULL modem.
Pro tips: 1) Windows may assign new COM ports to the adapters after every device sleep or reboot. 2) The market leaders in chips for USB to serial are Prolific and FTDI. Both companies are battling knockoffs, and may be blocked in future official Windows drivers. The Linux drivers however work fine with the clones.

There is a good explanation of why it is costly to use +
for concatenating a large number of strings here
Plus operator is perfectly fine solution to concatenate two Python strings. But if you keep adding more than two strings (n > 25) , you might want to think something else.
''.join([a, b, c])
trick is a performance optimization.
Try PyPDF2.
There is a good tutorial here: https://automatetheboringstuff.com/chapter13/
Adding onto @JoelEtherton's solution to fix a newly found security vulnerability. This vulnerability happens if users request HTTP and are redirected to HTTPS, but the sessionid cookie is set as secure on the first request to HTTP. That is now a security vulnerability, according to McAfee Secure.
This code will only secure cookies if request is using HTTPS. It will expire the sessionid cookie, if not HTTPS.
// this code will mark the forms authentication cookie and the
// session cookie as Secure.
if (Request.IsSecureConnection)
{
if (Response.Cookies.Count > 0)
{
foreach (string s in Response.Cookies.AllKeys)
{
if (s == FormsAuthentication.FormsCookieName || s.ToLower() == "asp.net_sessionid")
{
Response.Cookies[s].Secure = true;
}
}
}
}
else
{
//if not secure, then don't set session cookie
Response.Cookies["asp.net_sessionid"].Value = string.Empty;
Response.Cookies["asp.net_sessionid"].Expires = new DateTime(2018, 01, 01);

When you create a flex container various default flex rules come into play.
Two of these default rules are flex-direction: row
and align-items: stretch
. This means that flex items will automatically align in a single row, and each item will fill the height of the container.
If you don't want flex items to stretch – i.e., like you wrote:
make its height the minimum required for holding its content
... then simply override the default with align-items: flex-start
.
#a {_x000D_
display: flex;_x000D_
align-items: flex-start; /* NEW */_x000D_
}_x000D_
#a > div {_x000D_
background-color: red;_x000D_
padding: 5px;_x000D_
margin: 2px;_x000D_
}_x000D_
#b {_x000D_
height: auto;_x000D_
}
_x000D_
<div id="a">_x000D_
<div id="b">left</div>_x000D_
<div>_x000D_
right<br>right<br>right<br>right<br>right<br>_x000D_
</div>_x000D_
</div>
_x000D_
Here's an illustration from the flexbox spec that highlights the five values for align-items
and how they position flex items within the container. As mentioned before, stretch
is the default value.

In my case it works for me after adding this below version dependency(10.2.0.4). After adding this version 10.2.0.3.0 it doesn't work due to .jar file not avail in repository path.

A SELECT INTO
statement will throw an error if it returns anything other than 1 row. If it returns 0 rows, you'll get a no_data_found
exception. If it returns more than 1 row, you'll get a too_many_rows
exception. Unless you know that there will always be exactly 1 employee with a salary greater than 3000, you do not want a SELECT INTO
statement here.
Most likely, you want to use a cursor to iterate over (potentially) multiple rows of data (I'm also assuming that you intended to do a proper join between the two tables rather than doing a Cartesian product so I'm assuming that there is a departmentID
column in both tables)
BEGIN
FOR rec IN (SELECT EMPLOYEE.EMPID,
EMPLOYEE.ENAME,
EMPLOYEE.DESIGNATION,
EMPLOYEE.SALARY,
DEPARTMENT.DEPT_NAME
FROM EMPLOYEE,
DEPARTMENT
WHERE employee.departmentID = department.departmentID
AND EMPLOYEE.SALARY > 3000)
LOOP
DBMS_OUTPUT.PUT_LINE ('Employee Nnumber: ' || rec.EMPID);
DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
DBMS_OUTPUT.PUT_LINE ('Employee Name: ' || rec.ENAME);
DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
DBMS_OUTPUT.PUT_LINE ('Employee Designation: ' || rec.DESIGNATION);
DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
DBMS_OUTPUT.PUT_LINE ('Employee Salary: ' || rec.SALARY);
DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
DBMS_OUTPUT.PUT_LINE ('Employee Department: ' || rec.DEPT_NAME);
END LOOP;
END;
I'm assuming that you are just learning PL/SQL as well. In real code, you'd never use dbms_output
like this and would not depend on anyone seeing data that you write to the dbms_output
buffer.
There's an issue with selecting options in Firefox that Droogans's hack fixes that I want to mention here explicitly, hoping it might save someone some trouble: https://github.com/angular/protractor/issues/480.
Even if your tests are passing locally with Firefox, you might find that they're failing on CircleCI or TravisCI or whatever you're using for CI&deployment. Being aware of this problem from the beginning would have saved me a lot of time:)
The Python reference manual includes several string literals that can be used in a string. These special sequences of characters are replaced by the intended meaning of the escape sequence.
Here is a table of some of the more useful escape sequences and a description of the output from them.
Escape Sequence Meaning
\t Tab
\\ Inserts a back slash (\)
\' Inserts a single quote (')
\" Inserts a double quote (")
\n Inserts a ASCII Linefeed (a new line)
Basic Example
If i wanted to print some data points separated by a tab space I could print this string.
DataString = "0\t12\t24"
print (DataString)
Returns
0 12 24
Example for Lists
Here is another example where we are printing the items of list and we want to sperate the items by a TAB.
DataPoints = [0,12,24]
print (str(DataPoints[0]) + "\t" + str(DataPoints[1]) + "\t" + str(DataPoints[2]))
Returns
0 12 24
Raw Strings
Note that raw strings (a string which include a prefix "r"), string literals will be ignored. This allows these special sequences of characters to be included in strings without being changed.
DataString = r"0\t12\t24"
print (DataString)
Returns
0\t12\t24
Which maybe an undesired output
String Lengths
It should also be noted that string literals are only one character in length.
DataString = "0\t12\t24"
print (len(DataString))
Returns
7
The raw string has a length of 9.
1) Is the synthesize within @implementation
block?
2) Should you refer to self.classA = [[ClassA alloc] init];
and self.classA.downloadUrl = @"..."
instead of plain classA
?
3) In your myApp.m
file you need to import ClassA.h
, when it's missing it will default to a number, or pointer? (in C variables default to int if not found by compiler):
#import "ClassA.h"
.

Try
File.open("out.txt", "w") do |f|
f.write(data_you_want_to_write)
end
without using the

This function returns the ntfs Windows file details for any file using Cygwin bash (actual r-click-properties-info) to the term
Pass the files path to finfo(), can be unix path, dos path, relative or absolute. The file is converted into an absolute nix path, then checked to see if it is in-fact a regular/existing file. Then converted into an absolute windows path and sent to "wmic". Then magic, you have windows file details right in the terminal. Uses: cygwin, cygpath, sed, and awk. Needs Windows WMI "wmic.exe" to be operational. The output is corrected for easy...

$ finfo "C:\windows\system32\notepad.exe"
$ finfo /cygdrive/c/Windows/System32/notepad.exe

$ finfo ../notepad.exe
finfo() {
[[ -e "$(cygpath -wa "$@")" ]] || { echo "bad-file"; return 1; }

}
Try running the command
brew doctor
and let us know what sort of output you get
edit: And to answer the title question, this is from their FAQ :
Homebrew doesn’t write files outside its prefix. So generally you can just
rm -rf
the folder you installed it in.
So following that up with a clean re-install (following their latest recommended steps) should be your best bet.
We can't use "PHP in between JavaScript", because PHP runs on the server and JavaScript - on the client.
However we can generate JavaScript code as well as HTML, using all PHP features, including the escaping from HTML one.
This is what the standard has to say about operator==

Seems like there isn't much of a difference!
To change only the second column of a table use the following:
General Case:
table td + td{ /* this will go to the 2nd column of a table directly */
background:red
}
Your case:
.countTable table table td + td{
background: red
}

In order to make a pull request you need to do the following steps:
It took me a while to figure this, hope this will help someone.
I think I got there in the end.
The task is like this:
- name: Populate genders
set_fact:
genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
with_items: "{{ people.results }}"
It loops through each of the dicts (item
) in the people.results
array, each time creating a new dict like {Bob: "male"}
, and combine()
s that new dict in the genders
array, which ends up like:
{
"Bob": "male",
"Thelma": "female"
}
It assumes the keys (the name
in this case) will be unique.
I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items
:
- name: Populate genders
set_fact:
genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
with_items: "{{ people.results }}"
This keeps combining the existing list with a list containing a single dict. We end up with a genders
array like this:
[
{'name': 'Bob', 'gender': 'male'},
{'name': 'Thelma', 'gender': 'female'}
]
There are probably embedded tabs (CHAR(9)
) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:
DECLARE @var NVARCHAR(255), @i INT;
SET @i = 1;
SELECT @var = AccountType FROM dbo.Account
WHERE AccountNumber = 200
AND AccountType LIKE '%Daily%';
CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));
WHILE @i <= LEN(@var)
BEGIN
INSERT #x
SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));
SET @i = @i + 1;
END
SELECT i,c,a FROM #x ORDER BY i;
You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.
var result = list.GroupBy(x => x.Category).Select(x => x.First())
If you are using AUTOINCREMENT
, use:
SELECT LAST\_INSERT\_ID();
Assumming that you are using Mysql: http://dev.mysql.com/doc/refman/5.0/en/example-auto-increment.html
Postgres handles this similarly via the currval(sequence_name)
function.
Note that using MAX(ID)
is not safe, unless you lock the table, since it's possible (in a simplified case) to have another insert that occurs before you call MAX(ID)
and you lose the id of the first insert. The functions above are session based so if another session inserts you still get the ID that you inserted.
Assume Table1 and Table2 have three columns A, B and TimeStamp. I want to insert from Table1 into Table2.
This fails with the timestamp error:
Insert Into Table2
Select Table1.A, Table1.B, Table1.TimeStamp From Table1
This works:
Insert Into Table2
Select Table1.A, Table1.B, null From Table1
Please check your app's build.gradle. I had the same problem, finally I found the problem was in my build.gradle file dependencies{}, it add extra .jar file which actually didn't exist in my project as dependency. So I delete this dependency, and the problem has gone.
The first answer works very well, but for ZERO / 0 it will format as .00
Hence the format #,##0.00 is working well for me. Always test different numbers such as 0 / 100 / 2334.30 and negative numbers before deploying to production system.
You could always write out the list of keys in addition to dumping the dict, and then reconstruct the OrderedDict
by iterating through the list?
For a more cross-browser solution you could style all inputs the way you want the non-typed, text, and password then another style the overrides that style for radios, checkboxes, etc.
input { border:solid 1px red; }
input[type=radio],
input[type=checkbox],
input[type=submit],
input[type=reset],
input[type=file]
{ border:none; }
- Or -
could whatever part of your code that is generating the non-typed inputs give them a class like .no-type
or simply not output at all? Additionally this type of selection could be done with jQuery.

I did a fun hack to solve this issue to my satisfaction. I've got an AJAX site that loads content dynamically, then modifies the window.location.hash, and I had code to run upon $(document).ready() to parse the hash and load the appropriate section. The thing is that I was perfectly happy with my section loading code for navigation, but wanted to add a way to intercept the browser back and forward buttons, which change the window location, but not interfere with my current page loading routines where I manipulate the window.location, and polling the window.location at constant intervals was out of the question.
What I ended up doing was creating an object as such:
var pageload = {
ignorehashchange: false,
loadUrl: function(){
if (pageload.ignorehashchange == false){
//code to parse window.location.hash and load content
};
}
};
Then, I added a line to my site script to run the pageload.loadUrl
function upon the hashchange event, as such:
window.addEventListener("hashchange", pageload.loadUrl, false);
Then, any time I want to modify the window.location.hash
without triggering this page loading routine, I simply add the following line before each window.location.hash =
line:
pageload.ignorehashchange = true;
and then the following line after each hash modification line:
setTimeout(function(){pageload.ignorehashchange = false;}, 100);
So now my section loading routines are usually running, but if the user hits the 'back' or 'forward' buttons, the new location is parsed and the appropriate section loaded.
Go to Windows->Preferences->Validation.
There would be a list of validators with checkbox options for Manual & Build, go and individually disable the javascript validator there.
If you select the Suspend All Validators checkbox on the top it doesn't necessarily take affect.
Either I'm doing it wrongly, or the accepted answer does not work anymore with the current git.
I have actually found the proper solution and posted it under almost the same question here. For more details head there.
Solution:
# Ignore everything inside Resources/ directory
/Resources/**
# Except for subdirectories(won't be committed anyway if there is no committed file inside)
!/Resources/**/
# And except for *.foo files
!*.foo
Combining the earlier suggestions to determine your personal permissions (ie 'USER' permissions), then use this:
-- your permissions
select * from USER_ROLE_PRIVS where USERNAME= USER;
select * from USER_TAB_PRIVS where Grantee = USER;
select * from USER_SYS_PRIVS where USERNAME = USER;
-- granted role permissions
select * from ROLE_ROLE_PRIVS where ROLE IN (select granted_role from USER_ROLE_PRIVS where USERNAME= USER);
select * from ROLE_TAB_PRIVS where ROLE IN (select granted_role from USER_ROLE_PRIVS where USERNAME= USER);
select * from ROLE_SYS_PRIVS where ROLE IN (select granted_role from USER_ROLE_PRIVS where USERNAME= USER);
As pointed out, your hashcode implementation has too many collisions, and fixing it should result in decent performance. Moreover, caching hashCodes and implementing equals efficiently will help.
If you need to optimize even further:
By your description, there are only (52 * 51 / 2) * (52 * 51 * 50 / 6) = 29304600 different keys (of which 26000000, i.e. about 90%, will be present). Therefore, you can design a hash function without any collisions, and use a simple array rather than a hashmap to hold your data, reducing memory consumption and increasing lookup speed:
T[] array = new T[Key.maxHashCode];
void put(Key k, T value) {
array[k.hashCode()] = value;
T get(Key k) {
return array[k.hashCode()];
}
(Generally, it is impossible to design an efficient, collision-free hash function that clusters well, which is why a HashMap will tolerate collisions, which incurs some overhead)
Assuming a
and b
are sorted, you might use the following hash function:
public int hashCode() {
assert a[0] < a[1];
int ahash = a[1] * a[1] / 2
+ a[0];
assert b[0] < b[1] && b[1] < b[2];
int bhash = b[2] * b[2] * b[2] / 6
+ b[1] * b[1] / 2
+ b[0];
return bhash * 52 * 52 / 2 + ahash;
}
static final int maxHashCode = 52 * 52 / 2 * 52 * 52 * 52 / 6;
I think this is collision-free. Proving this is left as an exercise for the mathematically inclined reader.
Here is the same style as in large datasets:
x = df[:5]
y = pd.DataFrame([['...']*df.shape[1]], columns=df.columns, index=['...'])
z = df[-5:]
frame = [x, y, z]
result = pd.concat(frame)
print(result)
Output:
date temp

1 1981-01-02 00:00:00 17.9

I like Darin method. But quick way to solve this,
Html.TextBox("Expiry", null, new { style = "width: 70px;", maxlength = "10", id = "expire-date", disabled = "disabled" }).ToString().Replace("disabled=\"disabled\"", (1 == 2 ? "" : "disabled=\"disabled\""))
As of Java 8+ you can use the java.time package. Specifically, use DateTimeFormatterBuilder and DateTimeFormatter to format the patterns and literals.
DateTimeFormatter formatter = new DateTimeFormatterBuilder()
.appendPattern("MM").appendLiteral("/")
.appendPattern("dd").appendLiteral("/")
.appendPattern("yyyy").appendLiteral(" ")
.appendPattern("hh").appendLiteral(":")
.appendPattern("mm").appendLiteral(":")
.appendPattern("ss").appendLiteral(" ")
.appendPattern("a")
.toFormatter();
System.out.println(LocalDateTime.now().format(formatter));
The output ...
06/22/2015 11:59:14 AM
Or if you want different time zone…
// system default
System.out.println(formatter.withZone(ZoneId.systemDefault()).format(Instant.now()));
// Chicago
System.out.println(formatter.withZone(ZoneId.of("America/Chicago")).format(Instant.now()));
// Kathmandu
System.out.println(formatter.withZone(ZoneId.of("Asia/Kathmandu")).format(Instant.now()));
The output ...

I had a similar problem. I would suggest using the PIL
library in python as it draws the text in any given font, compared to limited fonts in OpenCV. With PIL you can choose any font installed on your system.
from PIL import ImageFont, ImageDraw, Image
import numpy as np
import cv2
image = cv2.imread("lena.png")
# Convert to PIL Image
cv2_im_rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
pil_im = Image.fromarray(cv2_im_rgb)
draw = ImageDraw.Draw(pil_im)
# Choose a font
font = ImageFont.truetype("Roboto-Regular.ttf", 50)
# Draw the text
draw.text((0, 0), "Your Text Here", font=font)
# Save the image
cv2_im_processed = cv2.cvtColor(np.array(pil_im), cv2.COLOR_RGB2BGR)
cv2.imwrite("result.png", cv2_im_processed)
The best way I found so far is to go to the Oauth playground here: https://developers.google.com/oauthplayground/
In the HTTP header for the REST API request, add: "Authorization: Bearer ". Here, Authorization is the key, and "Bearer ". For example: "Authorization: Bearer za29.KluqA3vRtZChWfJDabcdefghijklmnopqrstuvwxyz6nAZ0y6ElzDT3yH3MT5"
What i sometimes do when i need a lot of tablenames ill just get them plus their schema from the INFORMATION_SCHEMA system table: value
select TABLE_SCHEMA + '.' + TABLE_NAME from INFORMATION_SCHEMA.TABLES where TABLE_NAME in
(*select your table names*)
To get this working with YAML, do this:
property-name: '{
key1: "value1",
key2: "value2"
}'
The original conio.h was implemented by Borland, so its not a part of the C Standard Library nor is defined by POSIX.
But here is an implementation for Linux that uses ncurses to do the job.
if ($.inArray('yourElement', yourArray) > -1)
{
//yourElement in yourArray
//code here
}
Reference: Jquery Array
The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0.
This will loop through all cells in a given range that you define ("RANGE TO SEARCH")
and add dashes at the cell below using the Offset()
method. As a best practice in VBA, you should never use the Select
method.
Sub AddDashes()
Dim SrchRng As Range, cel As Range
Set SrchRng = Range("RANGE TO SEARCH")
For Each cel In SrchRng
If InStr(1, cel.Value, "TOTAL") > 0 Then
cel.Offset(1, 0).Value = "-"
End If
Next cel
End Sub
The i
flag is normally used for case insensitivity. You don't give a language here, but it'll probably be something like /G[ab].*/i
or /(?i)G[ab].*/
