l = [-1.2, 0.0, 1]
x = 100.0
for i in l:
if i < x:
x = i
print (x)
This is the answer, i needed this for my homework, took your code, and i deleted the " " around the numbers, it then worked, i hope this helped

You should also consider that in some Opera versions onload is fired several times and add some hooks:
// fixing Opera 9.26, 10.00
if (doc.readyState && doc.readyState != 'complete') {
// Opera fires load event multiple times
// Even when the DOM is not ready yet
// this fix should not affect other browsers
return;
}
// fixing Opera 9.64
if (doc.body && doc.body.innerHTML == "false") {
// In Opera 9.64 event was fired second time
// when body.innerHTML changed from false
// to server response approx. after 1 sec
return;
}

Is Button1
visible? I mean, from the server side. Make sure Button1.Visible is true.
Controls that aren't Visible
won't be rendered in HTML, so although they are assigned a ClientID
, they don't actually exist on the client side.

A Quote from : iPhone Developer Program (~8MB PDF)
A provisioning profile is a collection of digital entities that uniquely ties developers and devices to an authorized iPhone Development Team and enables a device to be used for testing. A Development Provisioning Profile must be installed on each device on which you wish to run your application code. Each Development Provisioning Profile will contain a set of iPhone Development Certificates, Unique Device Identifiers and an App ID. Devices specified within the provisioning profile can be used for testing only by those individuals whose iPhone Development Certificates are included in the profile. A single device can contain multiple provisioning profiles.
I think this will help you better

I think you could call the id, like this
{% for days in days_list %}
<h2># Day {{ days.id }} - From {{ days.from_location }} to {{ days.to_location }}</h2>
{% endfor %}
You should use some HTML parsing library like lxml
:
from lxml import etree
s = """<table>
<tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
<tr><td>a</td><td>b</td><td>c</td></tr>
<tr><td>d</td><td>e</td><td>f</td></tr>
<tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""
table = etree.HTML(s).find("body/table")
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
values = [col.text for col in row]
print dict(zip(headers, values))
prints
{'End Date': 'c', 'Start Date': 'b', 'Event': 'a'}
{'End Date': 'f', 'Start Date': 'e', 'Event': 'd'}
{'End Date': 'i', 'Start Date': 'h', 'Event': 'g'}
I have the same problem that you describe although I'm building up my LatLngBounds as proposed by above. The problem is that things are async and calling map.fitBounds()
at the wrong time may leave you with a result like in the Q.
The best way I found is to place the call in an idle handler like this:
google.maps.event.addListenerOnce(map, 'idle', function() {
map.fitBounds(markerBounds);
});
Outside of your loop create an int:
int numberOfItemIds = 0;
for (int i = 0; i < key.length; i++) {
Then in the loop, increment it:
itemId = p.getItemId();
numberOfItemIds++;
I had this issue and my problem was that I was calling my method with any()
instead of anyInt()
. So I had:
doAnswer(...).with(myMockObject).thisFuncTakesAnInt(any())
and I had to change it to:
doAnswer(...).with(myMockObject).thisFuncTakesAnInt(anyInt())
I have no idea why that produced a NullPointerException. Maybe this will help the next poor soul.
Here the passage from the MSDN:
When you specify a PRIMARY KEY constraint for a table, the Database Engine enforces data uniqueness by creating a unique index for the primary key columns. This index also permits fast access to data when the primary key is used in queries. Therefore, the primary keys that are chosen must follow the rules for creating unique indexes.
I'd like to give more codes to make it clear.
struct A
{
operator bool() const { return true; }
};
struct B
{
explicit operator bool() const { return true; }
};
int main()
{
A a1;
if (a1) cout << "true" << endl; // OK: A::operator bool()
bool na1 = a1; // OK: copy-initialization selects A::operator bool()
bool na2 = static_cast<bool>(a1); // OK: static_cast performs direct-initialization
B b1;
if (b1) cout << "true" << endl; // OK: B::operator bool()
// bool nb1 = b1; // error: copy-initialization does not consider B::operator bool()
bool nb2 = static_cast<bool>(b1); // OK: static_cast performs direct-initialization
}
To avoid the exception you need to do two things:
Add the System.Xml.Serialization.XmlSerializerAssembly attribute to your class. Replace 'MyAssembly' with the name of the assembly where MyClass is in.
[Serializable]
[XmlSerializerAssembly("MyAssembly.XmlSerializers")]
public class MyClass
{
…
}
Generate the serialization file using the sgen.exe utility and deploy it with the class’s assembly.
‘sgen.exe MyAssembly.dll’ will generate the file MyAssembly.XmlSerializers.dll
These two changes will cause the .net to directly find the assembly. I checked it and it works on .NET framework 3.5 with Visual Studio 2008
If you are using boost libs you can obtain a random generator in this way:
#include <iostream>
#include <string>
// Used in randomization
#include <ctime>
#include <boost/random/mersenne_twister.hpp>
#include <boost/random/uniform_int_distribution.hpp>
#include <boost/random/variate_generator.hpp>
using namespace std;

int current_time_nanoseconds(){
struct timespec tm;
clock_gettime(CLOCK_REALTIME, &tm);
return tm.tv_nsec;
}
int main (int argc, char* argv[]) {
unsigned int dice_rolls = 12;
random::mt19937 rng(current_time_nanoseconds());
random::uniform_int_distribution<> six(1,6);
for(unsigned int i=0; i<dice_rolls; i++){
cout << six(rng) << endl;
}
}
Where the function current_time_nanoseconds()
gives the current time in nanoseconds which is used as a seed.
Here is a more general class to get random integers and dates in a range:

It's HTTP Activation feature of .NET framework Windows Process Activation feature is required too
simpler with linq:
public void KillProcessesAssociatedToFile(string file)
{
GetProcessesAssociatedToFile(file).ForEach(x =>
{
x.Kill();
x.WaitForExit(10000);
});
}
public List<Process> GetProcessesAssociatedToFile(string file)
{
return Process.GetProcesses()
.Where(x => !x.HasExited
&& x.Modules.Cast<ProcessModule>().ToList()
.Exists(y => y.FileName.ToLowerInvariant() == file.ToLowerInvariant())
).ToList();
}
concurency: multiple execution flows with the potential to share resources
Ex: two threads competing for a I/O port.
paralelism: splitting a problem in multiple similar chunks.
Ex: parsing a big file by running two processes on every half of the file.
Maybe the author of that unnamed book has read that a > 0
runs faster than a >= 1
and thinks that is true universally.
But it is because a 0
is involved (because CMP
can, depending on the architecture, replaced e.g. with OR
) and not because of the <
.
If you add:
jquery.form.min.js
You can simply do this:
<script>
$('#myform').ajaxForm(function(response) {
alert(response);
});
// this will register the AJAX for <form id="myform" action="some_url">
// and when you submit the form using <button type="submit"> or $('myform').submit(), then it will send your request and alert response
</script>
You could use simple $('FORM').serialize() as suggested in post above, but that will not work for FILE INPUTS... ajaxForm() will.
Check the static Nullable.GetUnderlyingType
.
- If the underlying type is null, then the template parameter is not Nullable
, and we can use that type directly
- If the underlying type is not null, then use the underlying type in the conversion.
Seems to work for me:
public object Get( string _toparse, Type _t )
{
// Test for Nullable<T> and return the base type instead:
Type undertype = Nullable.GetUnderlyingType(_t);
Type basetype = undertype == null ? _t : undertype;
return Convert.ChangeType(_toparse, basetype);
}
public T Get<T>(string _key)
{
return (T)Get(_key, typeof(T));
}
public void test()
{
int x = Get<int>("14");
int? nx = Get<Nullable<int>>("14");
}
Javascript in URL will not be executed, on its own. That by no way means its safe or to be trusted.
A URL is another user input not to be trusted, GET or POST (or any other method for that matter) can cause allot of severe vulnerabilities.
A common example was/is the use of the PHP_SELF
, REQUEST_URI
, SCRIPT_NAME
and similar variables. Developers would mistakenly echo them directly to the browser which led to the script being injected into the page and executed.
I would suggest you start to do allot of reading, these are some good places to start:
Also google around for XSS (cross site scripting), XSRF (Cross Site Request Forgery), and SQL Injection. That will get you started, but it is allot of information to absorb so take your time. It will be worth it in the long run.
Let's assume we have an array of objects and you want to check if value of name is defined like this,
let persons = [ {"name" : "test1"},{"name": "test2"}];
if(persons.some(person => person.name == 'test1')) {
... here your code in case person.name is defined and available
}
You can try removing the width
and height
attributes on the svg root element, adding preserveAspectRatio="none" viewBox="0 0 1024 800"
instead. It makes a difference in Opera at least, assuming you wanted the svg to stretch to fill the entire region defined by the CSS styles.
You need a reference to the class that contains the method you want to call. Let's say we have two classes, A and B. B has a method you want to call from A. Class A would look like this:
public class A
{
B b; // A reference to B
b = new B(); // Creating object of class B
b.doSomething(); // Calling a method contained in class B from class A
}
B, which contains the doSomething() method would look like this:
public class B
{
public void doSomething()
{
System.out.println("Look, I'm doing something in class B!");
}
}
How to execute Python scripts in Windows?
You could install pylauncher. It is used to launch .py, .pyw, .pyc, .pyo files and supports multiple Python installations:
T\:> blah.py argument
You can run your Python script without specifying .py extension if you have .py, .pyw in PATHEXT environment variable:
T:\> blah argument
It adds support for shebang (#!
header line) to select desired Python version on Windows if you have multiple versions installed. You could use *nix-compatible syntax #! /usr/bin/env python
.
You can specify version explicitly e.g., to run using the latest installed Python 3 version:
T:\> py -3 blah.py argument
It should also fix your sys.argv
issue as a side-effect.
If you know you don't have any whitespace in the input:
xargs chmod 755 < file.txt
If there might be whitespace in the paths, and if you have GNU xargs:
tr '\n' '\0' < file.txt | xargs -0 chmod 755
You may use ReadFormattedLine subroutine for all kind of formatted input. For example, the command below read a password of 8 characters, display asterisks in the screen, and continue automatically with no need to press Enter:
call :ReadFormattedLine password="********" /M "Enter password (8 chars): "
This subroutine is written in pure Batch so it does not require any additional program, and it allows several formatted input operations, like read just numbers, convert letters to uppercase, etc. You may download ReadFormattedLine subroutine from Read a line with specific format.
EDIT 2018-08-18: New method to enter an "invisible" password
The FINDSTR command have a strange bug that happen when this command is used to show characters in color AND the output of such a command is redirected to CON device. For details on how use FINDSTR command to show text in color, see this topic.
When the output of this form of FINDSTR command is redirected to CON, something strange happens after the text is output in the desired color: all the text after it is output as "invisible" characters, although a more precise description is that the text is output as black text over black background. The original text will appear if you use COLOR command to reset the foreground and background colors of the entire screen. However, when the text is "invisible" we could execute a SET /P command, so all characters entered will not appear on the screen.
@echo off
setlocal
set /P "=_" < NUL > "Enter password"
findstr /A:1E /V "^$" "Enter password" NUL > CON
del "Enter password"
set /P "password="
cls
color 07
echo The password read is: "%password%"
Look for GSpread.NET. You can work with Google Spreadsheets by using API from Microsoft Excel. You don't need to rewrite old code with the new Google API usage. Just add a few row:
Set objExcel = CreateObject("GSpreadCOM.Application");
app.MailLogon(Name, ClientIdAndSecret, ScriptId);
It's an OpenSource project and it doesn't require Office to be installed.

I think the FM-index by Paolo Ferragina and Giovanni Manzini is really cool. Especially in bioinformatics. It's essentially a compressed full text index that utilizes a combination of a suffix array and a burrows-wheeler transform of the reference text. The index can be searched without decompressing the whole index.
I did it one time with a workaround, hope it helps.
string fullName = typeof(MyObj).FullName;
switch (fullName)

The answer is "No, one can't find the median of an arbitrary, unsorted dataset in linear time". The best one can do as a general rule (as far as I know) is Median of Medians (to get a decent start), followed by Quickselect. Ref: [https://en.wikipedia.org/wiki/Median_of_medians][1]
I got the same error when an imported library was trying to create a directory at path "./logs/".
It turns out that the library was trying to create it at the wrong location, i.e. inside the folder of my python interpreter instead of the base project directory. I solved the issue by setting the "Working directory" path to my project folder inside the "Run Configurations" menu of PyCharm. If instead you're using the terminal to run your code, maybe you just need to move inside the project folder before running it.
1) check if service declaration in manifest is nested in application tag
<application>
<service android:name="" />
</application>
2) check if your service.java
is in the same package or diff package as the activity
<application>
<!-- service.java exists in diff package -->
<service android:name="com.package.helper.service" />
</application>
<application>
<!-- service.java exists in same package -->

You can use JsonNode
for a structured tree representation of your JSON string. It's part of the rock solid jackson library which is omnipresent.
ObjectMapper mapper = new ObjectMapper();
JsonNode yourObj = mapper.readTree("{\"k\":\"v\"}");
The indexing e.g. [0] should occour inside of the print...
For floating point numbers there is a standard (IEEE754): floats are 32 bit and doubles are 64. This is a hardware standard, not a C++ standard, so compilers could theoretically define float and double to some other size, but in practice I've never seen an architecture that used anything different.

This isn't really possible in HTML unless you use absolute positioning or javascript. So one solution would be to give this CSS to #bottom_link:
#bottom_link {
position:absolute;
bottom:0;
}
Otherwise you'd have to use some javascript. Here's a jQuery block that should do the trick, depending on the simplicity of the page.
$('#bottom_link').css({
position: 'relative',
top: $(this).parent().height() - $(this).height()
});
To search for files not ending with ".tmp" we use the following regex:
^(?!.*[.]tmp$).*$
Tested with the Regex Tester gives following result:
As an alternative to using UsedRange or providing an explicit range address, the AutoFilter.Range property can also specify the affected range.
ActiveSheet.AutoFilter.Range.Offset(1,0).Rows.SpecialCells(xlCellTypeVisible).Delete(xlShiftUp)
As used here, Offset causes the first row after the AutoFilter range to also be deleted. In order to avoid that, I would try using .Resize() after .Offset().
There are 3 solutions:
Solution 1:
const char *x = "foo bar";
Solution 2:
char *x = (char *)"foo bar";
Solution 3:
char* x = (char*) malloc(strlen("foo bar")+1); // +1 for the terminator
strcpy(x,"foo bar");
Arrays also can be used instead of pointers because an array is already a constant pointer.
I found that The Boolean Expression Reducer is much easier to use than Logic Friday. Plus it doesn't require installation and is multi-platform (Java).
Also in Logic Friday the expression A | B
just returns 3 entries in truth table; I expected 4.
You can chain as much conditions as you want. If you do:
var x = (false)?("1true"):((true)?"2true":"2false");
You will get x="2true"
So it could be expressed as:
var variable = (condition) ? (true block) : ((condition)?(true block):(false block))

This is a repackaging of the accepted answer - but in a way that lets you compare them all to each other for yourself - the top 3 algorithms are compared (and comments explain why other methods are excluded) and you can run against your own setup to see how they each perform with the size of sequence that you desire.

Lots of the above helped for me, plus the accepted answer, but since I was on an EC2 instance, I had no idea what my instance name was. Finally, I opened SQLServer Configuration Manager and in the Name column, use whatever is there as your connection server, so in my case, .\EC2SQLEXPRESS and worked great!
I found out the hard way that if your listbox items are assigned via a data source
List<String> workTables = hhsdbutils.GetWorkTableNames();
listBoxWork.DataSource = workTables;
...you have to unbind that before doing the removal:
listBoxWork.DataSource = null;
for (int i = listBoxWork.Items.Count - 1; i >= 0; --i)
{
if (listBoxWork.Items[i].ToString().Contains(listboxVal))
{
listBoxWork.Items.RemoveAt(i);
}
}
Without the "listBoxWork.DataSource = null;
" line, I was getting, "Value does not fall within the expected range"
The solution involved putting the gtest source directory as a subdirectory of your project. I've included the working CMakeLists.txt below if it is helpful to anyone.

Since C++11 you could use std::put_time
from iomanip
header:
#include <iostream>
#include <iomanip>
#include <ctime>
int main()
{
auto t = std::time(nullptr);
auto tm = *std::localtime(&t);
std::cout << std::put_time(&tm, "%d-%m-%Y %H-%M-%S") << std::endl;
}
std::put_time
is a stream manipulator, therefore it could be used together with std::ostringstream
in order to convert the date to a string:
#include <iostream>
#include <iomanip>
#include <ctime>
#include <sstream>
int main()
{
auto t = std::time(nullptr);
auto tm = *std::localtime(&t);
std::ostringstream oss;
oss << std::put_time(&tm, "%d-%m-%Y %H-%M-%S");
auto str = oss.str();
std::cout << str << std::endl;
}
Answer given by Jeru Luke is working only on Windows systems, if we try on another operating system (Ubuntu) then it runs without error but the image is saved on target location or path.
import cv2
img = cv2.imread('1.jpg', 1)
path = '/tmp'
cv2.imwrite(str(path) + 'waka.jpg',img)
cv2.waitKey(0)
I run above code but the image does not save the image on target path. Then I found that the way of adding path is wrong for the general purpose we using OS module to add the path.
Example:
import os
final_path = os.path.join(path_1,path_2,path_3......)
import cv2
import os
img = cv2.imread('1.jpg', 1)
path = 'D:/OpenCV/Scripts/Images'
cv2.imwrite(os.path.join(path , 'waka.jpg'),img)
cv2.waitKey(0)
that code works fine on both Windows and Ubuntu :)
import java.util.ArrayList;
import java.util.List;
class ArrLst{
public static void main(String args[]){
List l=new ArrayList();
l.add(10);
l.add(11);
l.add(12);
l.add(13);
l.add(14);
l.forEach((a)->System.out.println(a));
}
}
Chain both class selectors (without a space in between):
.foo.bar {
/* Styles for element(s) with foo AND bar classes */
}
If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar
in this case) instead, regardless of what other classes you list.
To illustrate how other browsers and IE6 interpret this, consider this CSS:
* {
color: black;
}
.foo.bar {
color: red;
}
Output on supported browsers is:
<div class="foo">Hello Foo</div> <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div> <!-- Not selected, black text [3] -->
Output on IE6 is:
<div class="foo">Hello Foo</div> <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div> <!-- Selected, red text [2] -->
Footnotes:
foo
.foo
and bar
.bar
.
bar
.bar
, regardless of any other classes listed.Here is an example - accepting no parameters and returning nothing.
class CallbackTest
{
public myCallback: {(): void;};
public doWork(): void
{
//doing some work...
this.myCallback(); //calling callback
}
}
var test = new CallbackTest();
test.myCallback = () => alert("done");
test.doWork();
If you want to accept a parameter, you can add that too:
public myCallback: {(msg: string): void;};
And if you want to return a value, you can add that also:
public myCallback: {(msg: string): number;};
Old question, but there's an easier way.
sns.pointplot(x=x_col,y=y_col,data=df_1,color='blue')
sns.pointplot(x=x_col,y=y_col,data=df_2,color='green')
sns.pointplot(x=x_col,y=y_col,data=df_3,color='red')
plt.legend(labels=['legendEntry1', 'legendEntry2', 'legendEntry3'])
This lets you add the plots sequentially, and not have to worry about any of the matplotlib crap besides defining the legend items.
Robert Stewart have already answered for how to import with mongoimport.
I am suggesting easy way to import CSV elegantly with 3T MongoChef Tool (3.2+ version). Might help someone in future.
If you're positive that you will never use this code in a compiler that doesn't support it (Windows/VS, GCC, and Clang are examples of compilers that do support it), then you can certainly use #pragma once without worries.
You can also just use both (see example below), so that you get portability and compilation speedup on compatible systems
#pragma once
#ifndef _HEADER_H_
#define _HEADER_H_
...
#endif
Try to use an XPath expression for searching the element and then, the following code works:
driver.findElement(By.xpath(".//*[@id='txtFilterContentUnit']")).sendKeys(Keys.ENTER);
You override __hash__
if you want special hash-semantics, and __cmp__
or __eq__
in order to make your class usable as a key. Objects who compare equal need to have the same hash value.
Python expects __hash__
to return an integer, returning Banana()
is not recommended :)
User defined classes have __hash__
by default that calls id(self)
, as you noted.
There is some extra tips from the documentation.:
Classes which inherit a
__hash__()
method from a parent class but change the meaning of__cmp__()
or__eq__()
such that the hash value returned is no longer appropriate (e.g. by switching to a value-based concept of equality instead of the default identity based equality) can explicitly flag themselves as being unhashable by setting__hash__ = None
in the class definition. Doing so means that not only will instances of the class raise an appropriate TypeError when a program attempts to retrieve their hash value, but they will also be correctly identified as unhashable when checkingisinstance(obj, collections.Hashable)
(unlike classes which define their own__hash__()
to explicitly raise TypeError).
The difference is that non-constant pointer variable(not to be confused with a pointer to constant) may be changed at some time during program execution, requires pointer semantics to be used(&,*) operators, while references can be set upon initialization only(that's why you can set them in constructor initializer list only, but not somehow else) and use ordinary value accessing semantics. Basically references were introduced to allow support for operators overloading as I had read in some very old book. As somebody stated in this thread - pointer can be set to 0 or whatever value you want. 0(NULL, nullptr) means that the pointer is initialized with nothing. It is an error to dereference null pointer. But actually the pointer may contain a value that doesn't point to some correct memory location. References in their turn try not to allow a user to initialize a reference to something that cannot be referenced due to the fact that you always provide rvalue of correct type to it. Although there are a lot of ways to make reference variable be initialized to a wrong memory location - it is better for you not to dig this deep into details. On machine level both pointer and reference work uniformly - via pointers. Let's say in essential references are syntactic sugar. rvalue references are different to this - they are naturally stack/heap objects.
The simplest thing to do could be to use dynamics, i.e. you define the simple methods like in Yuval Peled answer:
void Test(WebControl c)
{
...
}
void Test(ComboBox c)
{
...
}
Then you cannot call directly Test(obj), because overload resolution is done at compile time. You have to assign your object to a dynamic and then call the Test method:
dynamic dynObj = obj;
Test(dynObj);
See following snippet :
$(document).on("click", "a.deleteText", function() {_x000D_
if (confirm('Are you sure ?')) {_x000D_
$(this).prev('span.text').remove();_x000D_
}_x000D_
});

Assuming you are testing via mocha
, you have to run your tests using the mocha
command instead of the node
executable.
So if you haven't already, make sure you do npm install mocha -g
. Then just run mocha
in your project's root directory.
Very important note regarding use of Lookup:
You can create an instance of a Lookup(TKey, TElement)
by calling ToLookup
on an object that implements IEnumerable(T)
There is no public constructor to create a new instance of a Lookup(TKey, TElement)
. Additionally, Lookup(TKey, TElement)
objects are immutable, that is, you cannot add or remove elements or keys from a Lookup(TKey, TElement)
object after it has been created.
I'd think this would be a show stopper for most uses.
FuzzyFinder has been mentioned, however I love the textmate like behaviour of the FuzzyFinderTextmate plugin which extends the behaviour to include all subdirs.
Make sure you are using version 2.16 of fuzzyfinder.vim - The higher versions break the plugin.
In cases where you don't want the metaclass-based solution above, and you don't like the simple function decorator-based approach (e.g. because in that case static methods on the singleton class won't work), this compromise works:
class singleton(object):
"""Singleton decorator."""
def __init__(self, cls):
self.__dict__['cls'] = cls
instances = {}
def __call__(self):
if self.cls not in self.instances:
self.instances[self.cls] = self.cls()
return self.instances[self.cls]
def __getattr__(self, attr):
return getattr(self.__dict__['cls'], attr)
def __setattr__(self, attr, value):
return setattr(self.__dict__['cls'], attr, value)
df["col_name"].str.rjust(4,'0')#(length of string,'value') --> ValueXXX --> 0XXX
df["col_name"].str.ljust(4,'0')#(length of string,'value') --> XXXValue --> XXX0
It is good programming practice to return an empty array []
if the expected return type is an array. This makes sure that the receiver of the json can treat the value as an array immediately without having to first check for null. It's the same way with empty objects using open-closed braces {}
.
Strings, Booleans and integers do not have an 'empty' form, so there it is okay to use null values.
This is also addressed in Joshua Blochs excellent book "Effective Java". There he describes some very good generic programming practices (often applicable to other programming langages as well). Returning empty collections instead of nulls is one of them.
Here's a link to that part of his book:
http://jtechies.blogspot.nl/2012/07/item-43-return-empty-arrays-or.html

Look in the Cmakelists.txt if you find ARM you need to install C++ for ARM
It's these packages:
C++ Universal Windows Platform for ARM64 "Not Required"
Visual C++ Compilers and libraries for ARM "Not Required"
Visual C++ Compilers and libraries for ARM64 "Very Likely Required"
Required for finding Threads on ARM
enable_language(C)
enable_language(CXX)
Then the problems
No CMAKE_C_COMPILER could be found.
No CMAKE_CXX_COMPILER could be found.
Might disappear unless you specify c compiler like clang, and maybe installing clang will work in other favour.
You can with optional remove in cmakelists.txt both with # before enable_language if you are not compiling for ARM.
Since C++11, you can simply use lambda expressions to initialize static class members. This even works with const
static members as well. You can also impose an order of construction between multiple static class members, since static members are always initialized in the order as defined within the source file.
Header file:
class MyClass {
static const vector<char> letters;
};
Source file:
const vector<char> MyClass::letters = [] {
vector<char> letters;
for (char c = 'a'; c <= 'z'; c++)
letters.push_back(c);
return letters;
}();
This is just main
and Ctrl-Space.

OP's sample code is incorrect.
Endian conversion works at the bit and 8-bit byte level. Most endian issues deal with the byte level. OP code is doing a endian change at the 4-bit nibble level. Recommend instead:
// Swap endian (big to little) or (little to big)
uint32_t num = 9;
uint32_t b0,b1,b2,b3;
uint32_t res;
b0 = (num & 0x000000ff) << 24u;
b1 = (num & 0x0000ff00) << 8u;
b2 = (num & 0x00ff0000) >> 8u;
b3 = (num & 0xff000000) >> 24u;
res = b0 | b1 | b2 | b3;
printf("%" PRIX32 "\n", res);
If performance is truly important, the particular processor would need to be known. Otherwise, leave it to the compiler.
[Edit] OP added a comment that changes things.
"32bit numerical value represented by the hexadecimal representation (st uv wx yz) shall be recorded in a four-byte field as (st uv wx yz)."
It appears in this case, the endian of the 32-bit number is unknown and the result needs to be store in memory in little endian order.
uint32_t num = 9;
uint8_t b[4];
b[0] = (uint8_t) (num >> 0u);
b[1] = (uint8_t) (num >> 8u);
b[2] = (uint8_t) (num >> 16u);
b[3] = (uint8_t) (num >> 24u);
[2016 Edit] Simplification
... The type of the result is that of the promoted left operand.... Bitwise shift operators C11 §6.5.7 3
Using a u
after the shift constants (right operands) results in the same as without it.
b3 = (num & 0xff000000) >> 24u;
b[3] = (uint8_t) (num >> 24u);
// same as
b3 = (num & 0xff000000) >> 24;
b[3] = (uint8_t) (num >> 24);

The difference is in how you create and append elements in the DOM.
If you create an element via document.createElement
, add an event listener, and append it to the DOM. Your events will fire.
If you create an element as a string like this: html += "<li>test</li>"`, the elment is technically just a string. Strings cannot have event listeners.
One solution is to create each element with document.createElement
and then add those to a DOM element directly.
// Sample
let li = document.createElement('li')
document.querySelector('ul').appendChild(li)
You can use Google's Gson library to convert json to Hashmap. Try below code
String jsonString = "Your JSON string";
HashMap<String,String> map = new Gson().fromJson(jsonString, new TypeToken<HashMap<String, String>>(){}.getType());
listView1.View = View.Details;
listView1.Columns.Add("Target No.", 83, HorizontalAlignment.Center);
listView1.Columns.Add(" Range ", 100, HorizontalAlignment.Center);
listView1.Columns.Add(" Azimuth ", 100, HorizontalAlignment.Center);
i also had same problem .. i drag column to left .. but now ok .. so let's say i have 283*196 size of listview ..... We declared in the column width -2 for auto width .. For fitting in the listview ,we can divide listview width into 3 parts (83,100,100) ...

Here is what I did (for text). In the code, I copy whatever text is needed to clipboard. The first time an individual tries to use the share intent button, I pop up a notification that explains if they wish to share to facebook, they need to click 'Facebook' and then long press to paste (this is to make them aware that Facebook has BROKEN the android intent system). Then the relevant information is in the field. I might also include a link to this post so users can complain too...

For some reason Louise's answer didn't work for me I had to:
-Open anaconda prompt and generate the config file for Jupyter: jupyter notebook --generate-config
-Open the newly created config file at: C:\Users\builder\.juptyer\jupyter_notebook_config.py
-Add the following to the file:
import webbrowser
webbrowser.register('chrome', None, webbrowser.GenericBrowser(r'C:\Program Files (x86)\Google\Chrome\Application\chrome.exe'))
c.NotebookApp.browser = 'chrome'
CKEDITOR.config.enterMode = CKEDITOR.ENTER_BR;
- this works perfectly for me.
Have you tried clearing your browser cache - this is an issue sometimes.
You can also check it out with the jQuery adapter:
<script type="text/javascript" src="/js/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="/js/ckeditor/adapters/jquery.js"></script>
<script type="text/javascript">
$(function() {
$('#your_textarea').ckeditor({
toolbar: 'Full',
enterMode : CKEDITOR.ENTER_BR,
shiftEnterMode: CKEDITOR.ENTER_P
});
});
</script>
UPDATE according to @Tomkay's comment:
Since version 3.6 of CKEditor you can configure if you want inline content to be automatically wrapped with tags like <p></p>
. This is the correct setting:
CKEDITOR.config.autoParagraph = false;
Source: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.autoParagraph
If you have a dom object of the ul, use the following.
$('#my_ul').children().length;
A simple example
window.setInterval(function() {_x000D_
let ul = $('#ul'); // Get the ul_x000D_
let length = ul.children().length; // Count of the child nodes._x000D_
_x000D_
// The show!_x000D_
ul.append('<li>Item ' + (length + 1) + '</li>');_x000D_
if (5 <= length) {_x000D_
ul.empty();_x000D_
length = -1;_x000D_
}_x000D_
$('#ul_length').text(length + 1);_x000D_

According to the System.Net.Http.Formatting NuGet package page, the System.Net.Http.Formatting

onSelect doesn't work well in ng-repeat, so I made another version using event bind
html
<tr ng-repeat="product in products">
<td>
<input type="text" ng-model="product.startDate" class="form-control date-picker" data-date-format="yyyy-mm-dd" datepicker/>
</td>

script
angular.module('app', []).directive('datepicker', function () {
return {
restrict: 'A',
require: 'ngModel',
link: function (scope, element, attrs, ngModelCtrl) {
element.datepicker();
element.bind('blur keyup change', function(){
var model = attrs.ngModel;
if (model.indexOf(".") > -1) scope[model.replace(/\.[^.]*/, "")][model.replace(/[^.]*\./, "")] = element.val();
else scope[model] = element.val();
});
}
};
});
Actually, I think this is the best way.
from django.core.validators import URLValidator
from django.core.exceptions import ValidationError
val = URLValidator(verify_exists=False)
try:
val('http://www.google.com')
except ValidationError, e:
print e
If you set verify_exists
to True
, it will actually verify that the URL exists, otherwise it will just check if it's formed correctly.
edit: ah yeah, this question is a duplicate of this: How can I check if a URL exists with Django’s validators?

So what's on this hidden sheet? Proprietary information like price formulas, or client names, or employee salaries? Putting that info in even an hidden tab probably isn't the greatest idea to begin with.
yield
?The yield
keyword returns data from a generator function:
The heart of a generator function is the yield keyword. In its simplest form, a yield statement looks much like a return statement, except that instead of stopping execution of the function and returning, yield instead provides a value to the code looping over the generator and pauses execution of the generator function.
A generator function is effectively a more compact and efficient way to write an Iterator. It allows you to define a function (your xrange
) that will calculate and return values while you are looping over it:
function xrange($min, $max) {
for ($i = $min; $i <= $max; $i++) {
yield $i;
}
}
[…]
foreach (xrange(1, 10) as $key => $value) {
echo "$key => $value", PHP_EOL;
}
This would create the following output:
0 => 1
1 => 2
…
9 => 10
You can also control the $key
in the foreach
by using
yield $someKey => $someValue;
In the generator function, $someKey
is whatever you want appear for $key
and $someValue
being the value in $val
. In the question's example that's $i
.
Now you might wonder why we are not simply using PHP's native range
function to achieve that output. And right you are. The output would be the same. The difference is how we got there.
When we use range
PHP, will execute it, create the entire array of numbers in memory and return
that entire array to the foreach
loop which will then go over it and output the values. In other words, the foreach
will operate on the array itself. The range
function and the foreach
only "talk" once. Think of it like getting a package in the mail. The delivery guy will hand you the package and leave. And then you unwrap the entire package, taking out whatever is in there.
When we use the generator function, PHP will step into the function and execute it until it either meets the end or a yield
keyword. When it meets a yield
, it will then return whatever is the value at that time to the outer loop. Then it goes back into the generator function and continues from where it yielded. Since your xrange
holds a for
loop, it will execute and yield until $max
was reached. Think of it like the foreach
and the generator playing ping pong.
Obviously, generators can be used to work around memory limits. Depending on your environment, doing a range(1, 1000000)
will fatal your script whereas the same with a generator will just work fine. Or as Wikipedia puts it:
Because generators compute their yielded values only on demand, they are useful for representing sequences that would be expensive or impossible to compute at once. These include e.g. infinite sequences and live data streams.
Generators are also supposed to be pretty fast. But keep in mind that when we are talking about fast, we are usually talking in very small numbers. So before you now run off and change all your code to use generators, do a benchmark to see where it makes sense.
Another Use Case for Generators is asynchronous coroutines. The yield
keyword does not only return values but it also accepts them. For details on this, see the two excellent blog posts linked below.
yield
?Generators have been introduced in PHP 5.5. Trying to use yield
before that version will result in various parse errors, depending on the code that follows the keyword. So if you get a parse error from that code, update your PHP.
Simple Soltion
UPDATE `table_name`
SET `field_name` = replace(same_field_name, 'unwanted_text', 'wanted_text')
if not exist "%USERPROFILE%\.qgis-custom\" (
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
)
You have it almost done. The logic is correct, just some little changes.
This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).
If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.
If everyting is ok, files are copied.
All paths are quoted to avoid problems with spaces.
It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
In both code samples, files are not copied if the folder is not being created during the script execution.
EDITED - As dbenham comments, the same code can be written as a single line
md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
The code after the &&
will only be executed if the previous command does not set errorlevel. If mkdir
fails, xcopy
is not executed.
I usually write something like this:
foreach($_GET as $key=>$content){
echo "<input type='hidden' name='$key' value='$content'/>";
}
This is working, but don't forget to sanitize your inputs against XSS attacks!
Since when the edit is complete the focus from the element is always lost you could simply use the onBlur hook.
<div onBlur={(e)=>{console.log(e.currentTarget.textContent)}} contentEditable suppressContentEditableWarning={true}>
<p>Lorem ipsum dolor.</p>
</div>
Pandas: How to replace NaN (nan
) values with the average (mean), median or other statistics of one column
Say your DataFrame is df
and you have one column called nr_items
. This is: df['nr_items']
If you want to replace the NaN
values of your column df['nr_items']
with the mean of the column:
Use method .fillna()
:
mean_value=df['nr_items'].mean()
df['nr_item_ave']=df['nr_items'].fillna(mean_value)
I have created a new df
column called nr_item_ave
to store the new column with the NaN
values replaced by the mean
value of the column.
You should be careful when using the mean
. If you have outliers is more recommendable to use the median
I did not have the /usr/local/Frameworks
folder, so this fixed it for me
sudo mkdir -p /usr/local/Frameworks
sudo chown -R $(whoami) /usr/local/Frameworks
The first line creates a new Frameworks folder for homebrew (brew) to use. The second line gives that folder your current user permissions, which are sufficient.
Used commands are as follows:
mkdir - make directories [-p no error if existing, make parent directories as needed]
chown - change file owner and group [-R operate on files and directories recursively]
whoami - print effective userid
I have OSX High Sierra
You could try using LocationManager.addGpsStatusListener to get updated when the GPS status changes. It looks like GPS_EVENT_STARTED and GPS_EVENT_STOPPED might be what you're looking for.
An addition to the solution by @Rafael Teles. The syntactic sugar Collectors.mapping
does the same in one step:
//...
List<Employee> employees = persons.stream()
.filter(p -> p.getLastName().equals("l1"))
.collect(
Collectors.mapping(
p -> new Employee(p.getName(), p.getLastName(), 1000),
Collectors.toList()));

A little late to the party but I thought I would try to clear up some common misconceptions in jQuery event handlers. As of jQuery 1.7, .on()
should be used instead of the deprecated .live()
, to delegate event handlers to elements that are dynamically created at any point after the event handler is assigned.
That said, it is not a simple of switching live
for on
because the syntax is slightly different:
New method (example 1):
$(document).on('click', '#someting', function(){
});
Deprecated method (example 2):
$('#something').live(function(){
});
As shown above, there is a difference. The twist is .on()
can actually be called similar to .live()
, by passing the selector to the jQuery function itself:
Example 3:
$('#something').on('click', function(){
});
However, without using $(document)
as in example 1, example 3 will not work for dynamically created elements. The example 3 is absolutely fine if you don't need the dynamic delegation.
Should $(document).on() be used for everything?
It will work but if you don't need the dynamic delegation, it would be more appropriate to use example 3 because example 1 requires slightly more work from the browser. There won't be any real impact on performance but it makes sense to use the most appropriate method for your use.
Should .on() be used instead of .click() if no dynamic delegation is needed?
Not necessarily. The following is just a shortcut for example 3:
$('#something').click(function(){
});
The above is perfectly valid and so it's really a matter of personal preference as to which method is used when no dynamic delegation is required.
References:
It is the solution that I found for this problem:
//If IE
inputElement.writeAttribute("unselectable", "on");
//Other browsers
inputElement.writeAttribute("disabled", "disabled");
By using this trick, you can add style sheet to your input element that works in IE and other browsers on your not-editable input box.
Currently you can't access the arrays named name and country, because they are member variables of your Athelete class.
Based on what it looks like you're trying to do, this will not work.
These arrays belong in your main class.
To store a file in a directory
which is foreign to the app's directory is restricted above API 29+
. So to generate a new file or to create a new file use your application directory like this :-
So the correct approach is :-
val file = File(appContext.applicationInfo.dataDir + File.separator + "anyRandomFileName/")
You can write any data into this generated file !
The above file
is accessible and would not throw any exception
because it resides in your own developed app's directory.
The other option is android:requestLegacyExternalStorage="true"
in manifest application tag
as suggested by Uriel
but its not a permanent solution !
If you are using ggplot2
to generate a figure, then a ggsave(file="name.eps")
will also work.
@Mikael Svenson's answer is correct. I just wanted to add a small addition to it:
The Messagebox icon can also be included has an additional property like below:
DialogResult dialogResult = MessageBox.Show("Sure", "Please Confirm Your Action", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
When you say you increased MAVEN_OPTS
, what values did you increase? Did you increase the MaxPermSize
, as in example:
export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m"
(or on Windows:)
set MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=128m
You can also specify these JVM options in each maven project separately.
Try this:
UITextField *theTextFiels=[[UITextField alloc]initWithFrame:CGRectMake(40, 40, 150, 30)];
theTextFiels.borderStyle=UITextBorderStyleNone;
theTextFiels.layer.cornerRadius=8.0f;
theTextFiels.layer.masksToBounds=YES;
theTextFiels.backgroundColor=[UIColor redColor];
theTextFiels.layer.borderColor=[[UIColor blackColor]CGColor];
theTextFiels.layer.borderWidth= 1.0f;
[self.view addSubview:theTextFiels];
[theTextFiels release];
and import QuartzCore:
#import <QuartzCore/QuartzCore.h>
In HTML5, the easiest, and fastest, way to center your <th>THcontent</th>
is to add a colspan
like this:
<th colspan="3">Thcontent</th>
This will work if your table is three columns. So if you have a four-column table, add a colspan
of 4, etc.
You can manage the location furthermore in the CSS file while you have put your colspan
in HTML like I said.
th {
text-align: center; /* Or right or left */
}
You don't really need a sub-select:
SELECT a, COUNT(*) AS b,
SUM( CASE WHEN c = 'const' THEN 1 ELSE 0 END ) as d,
from t group by a order by b desc
Here's my version:
Utils.eventBoundToFunction = function (element, eventType, fCallback) {
if (!element || !element.data('events') || !element.data('events')[eventType] || !fCallback) {
return false;
}
for (runner in element.data('events')[eventType]) {
if (element.data('events')[eventType][runner].handler == fCallback) {
return true;
}
}
return false;
};
Usage:
Utils.eventBoundToFunction(okButton, 'click', handleOkButtonFunction)
just return true inside your if statement
var myArr = [1,2,3,4];
myArr.forEach(function(elem){
if (elem === 3) {
return true;
// Go to "next" iteration. Or "continue" to next iteration...
}
console.log(elem);
});
import numpy as np
def find_nearest(array, value):
array = np.asarray(array)
idx = (np.abs(array - value)).argmin()
return array[idx]
array = np.random.random(10)
print(array)
# [ 0.21069679 0.61290182 0.63425412 0.84635244 0.91599191 0.00213826
# 0.17104965 0.56874386 0.57319379 0.28719469]
value = 0.5
print(find_nearest(array, value))
# 0.568743859261
For 2D arrays, you can do this. Create a 2D mask using the condition. Typecast the condition mask to int or float, depending on the array, and multiply it with the original array.
In [8]: arr
Out[8]:
array([[ 1., 2., 3., 4., 5.],
[ 6., 7., 8., 9., 10.]])
In [9]: arr*(arr % 2 == 0).astype(np.int)
Out[9]:
array([[ 0., 2., 0., 4., 0.],
[ 6., 0., 8., 0., 10.]])
Yes, its definitely possible to avoid the intermediate conversion to JSON. Using a deep-copy tool like Dozer you can convert the map directly to a POJO. Here is a simplistic example:
Example POJO:
public class MyPojo implements Serializable {
private static final long serialVersionUID = 1L;
private String id;
private String name;
private Integer age;
private Double savings;
public MyPojo() {
super();
}
// Getters/setters
@Override
public String toString() {
return String.format(
"MyPojo[id = %s, name = %s, age = %s, savings = %s]", getId(),
getName(), getAge(), getSavings());
}
}
Sample conversion code:
public class CopyTest {
@Test
public void testCopyMapToPOJO() throws Exception {
final Map<String, String> map = new HashMap<String, String>(4);
map.put("id", "5");
map.put("name", "Bob");
map.put("age", "23");
map.put("savings", "2500.39");
map.put("extra", "foo");
final DozerBeanMapper mapper = new DozerBeanMapper();
final MyPojo pojo = mapper.map(map, MyPojo.class);
System.out.println(pojo);
}
}
Output:
MyPojo[id = 5, name = Bob, age = 23, savings = 2500.39]
Note: If you change your source map to a Map<String, Object>
then you can copy over arbitrarily deep nested properties (with Map<String, String>
you only get one level).

First you can subclass urllib2.BaseHandler
or urllib2.HTTPBasicAuthHandler
, and implement http_request
so that each request has the appropriate Authorization
header.
import urllib2
import base64
class PreemptiveBasicAuthHandler(urllib2.HTTPBasicAuthHandler):
'''Preemptive basic auth.
Instead of waiting for a 403 to then retry with the credentials,
send the credentials if the url is handled by the password manager.
Note: please use realm=None when calling add_password.'''
def http_request(self, req):
url = req.get_full_url()
realm = None
# this is very similar to the code from retry_http_basic_auth()
# but returns a request object.
user, pw = self.passwd.find_user_password(realm, url)
if pw:
raw = "%s:%s" % (user, pw)
auth = 'Basic %s' % base64.b64encode(raw).strip()
req.add_unredirected_header(self.auth_header, auth)
return req
https_request = http_request
Then if you are lazy like me, install the handler globally
api_url = "http://api.foursquare.com/"
api_username = "johndoe"
api_password = "some-cryptic-value"
auth_handler = PreemptiveBasicAuthHandler()
auth_handler.add_password(
realm=None, # default realm.
uri=api_url,
user=api_username,
passwd=api_password)
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)
Authentication is the process of confirming a user or computer’s identity. The process normally consists of four steps: The user makes a claim of identity, usually by providing a username. For example, I might make this claim by telling a database that my username is “mchapple”. The system challenges the user to prove his or her identity. The most common challenge is a request for a password. The user responds to the challenge by providing the requested proof. In this example, I would provide the database with my password The system verifies that the user has provided acceptable proof by, for example, checking the password against a local password database or using a centralized authentication server
If don't store it locally and use the link that they provide you might have an improved performance.The client might have the scripts already cached in some cases. As for the case of jQueryUI i would recommend not loading it until necessary. They are both minimized, but you can fire up the console and look at the network tab and see how long it takes for it to load, once it is initially downloaded it will be cached so you shouldn't worry afterwards.My conclusion would be yes use them both but use a CDN
This is your primary problem:
The source date could be anything like dd-mm-yyyy, dd/mm/yyyy, mm-dd-yyyy, mm/dd/yyyy or even yyyy-MM-dd.
If you're given 01/02/2013
, is it Jan 2 or Feb 1? You should solve this problem first and parsing the input will be much easier.
I suggest you take a step back and explore what you are trying to solve in more detail.
I've used Blat ( http://www.blat.net/ ) for many years. It's a simple command line utility that can send email from command line. It's free and opensource.
You can use command like "Blat myfile.txt -to [email protected] -server smtp.domain.com -port 6000"
Here is some other software you can try to send email from command line (I've never used them):
http://caspian.dotconf.net/menu/Software/SendEmail/
http://www.petri.co.il/sendmail.htm
http://www.petri.co.il/software/mailsend105.zip
http://retired.beyondlogic.org/solutions/cmdlinemail/cmdlinemail.htm
Here ( http://www.petri.co.il/send_mail_from_script.htm ) you can find other various way of sending email from a VBS script, plus link to some of the mentioned software
The following VBScript code is taken from that page
Set objEmail = CreateObject("CDO.Message")
objEmail.From = "[email protected]"
objEmail.To = "[email protected]"
objEmail.Subject = "Server is down!"
objEmail.Textbody = "Server100 is no longer accessible over the network."
objEmail.Send
Save the file as something.vbs
Set Msg = CreateObject("CDO.Message")
With Msg
.To = "[email protected]"
.From = "[email protected]"
.Subject = "Hello"
.TextBody = "Just wanted to say hi."
.Send
End With
Save the file as something2.vbs
I think these VBS scripts use the windows default mail server, if present. I've not tested these scripts...
Your'e casting a boolean to boolean and expecting an integer to be displayed. It works for true
but not false. Since you expect an integer:
echo (int)$bool_val;
It looks like you are trying to use (almost) straight up C code here. Go has a few differences.
const
. The term const
has a different meaning in Go, as it does in C. The list should be defined as var
instead.basenameOpts
as opposed to basename_opts
.char
type in Go. You probably want byte
(or rune
if you intend to allow unicode codepoints).var x = foo
.For example:
type opt struct {
shortnm byte
longnm, help string
needArg bool
}
var basenameOpts = []opt {
opt {
shortnm: 'a',
longnm: "multiple",
needArg: false,
help: "Usage for a",
},
opt {
shortnm: 'b',
longnm: "b-option",
needArg: false,
help: "Usage for b",
},
}
An alternative is to declare the list with its type and then use an init
function to fill it up. This is mostly useful if you intend to use values returned by functions in the data structure. init
functions are run when the program is being initialized and are guaranteed to finish before main
is executed. You can have multiple init
functions in a package, or even in the same source file.
type opt struct {
shortnm byte
longnm, help string
needArg bool
}
var basenameOpts []opt
func init() {
basenameOpts = []opt{
opt {
shortnm: 'a',
longnm: "multiple",
needArg: false,
help: "Usage for a",
},
opt {
shortnm: 'b',
longnm: "b-option",
needArg: false,
help: "Usage for b",
},
}
}
Since you are new to Go, I strongly recommend reading through the language specification. It is pretty short and very clearly written. It will clear a lot of these little idiosyncrasies up for you.
$query = "SELECT * FROM tableName";
$query_run = mysql_query($query);
$qty= 0;
while ($num = mysql_fetch_assoc ($query_run)) {
$qty += $num['ColumnName'];
}
echo $qty;
with pretty-print format:
import json
with open(path_to_file, 'w') as file:
json_string = json.dumps(sample, default=lambda o: o.__dict__, sort_keys=True, indent=2)
file.write(json_string)
I got it to work by Enabling 32 bit applications in the Application Pool advanced settings. Right click on the application pool and choose advanced settings - enable 32 bit applications. This may help someone out there.
I had the same problem on Windows. I used to read the file in scala line by line with
Source.fromFile(path).getLines()
Now I read it as a whole with
import org.apache.commons.io.FileUtils._
// encoding is null for platform default
val content=readFileToString(new File(path),null.asInstanceOf[String])
which closes the file properly after reading and now
new File(path).delete
works.
A quick way is :
String dateText ="Thu, 02 Jul 2015 21:51:46";
long hours = -5; // time difference between places
DateTimeFormatter formatter = DateTimeFormatter.ofPattern(E, dd MMM yyyy HH:mm:ss, Locale.ENGLISH);
LocalDateTime date = LocalDateTime.parse(dateText, formatter);
date = date.with(date.plusHours(hours));
System.out.println("NEW DATE: "+date);
Output
NEW DATE: 2015-07-02T16:51:46
While : your condition is at the begin of the loop block, and makes possible to never enter the loop.
Do While : your condition is at the end of the loop block, and makes obligatory to enter the loop at least one time.
If you are running the container as a service
using docker swarm
, you can do:
docker service update --env-add <you environment variable> <service_name>
Also remove using --env-rm
To make sure it's addedd as you wanted, just run:
docker exec -it <container id> env
Apart from the fine answers already given, you can also use ceilf(f) == f
or floorf(f) == f
. Both expressions return true
if f
is an integer. They also returnfalse
for NaNs (NaNs always compare unequal) and true
for ±infinity, and don't have the problem with overflowing the integer type used to hold the truncated result, because floorf()
/ceilf()
return float
s.

Make sure you're doing this for a good reason, a simple function like the following would allow static typing and allows your IDE to do things like "Find References" and Refactor -> Rename.
public Task <T> factory (String name)
{
Task <T> result;
if (name.CompareTo ("A") == 0)
{
result = new TaskA ();
}
else if (name.CompareTo ("B") == 0)
{
result = new TaskB ();
}
return result;
}
I had several issues that I put the following line in a wrong place:
signingConfigs {
release {
// We can leave these in environment variables
storeFile file("d:\\Fejlesztés\\******.keystore")
keyAlias "mykey"
// These two lines make gradle believe that the signingConfigs
// section is complete. Without them, tasks like installRelease
// will not be available!
storePassword "*****"
keyPassword "******"
}
}
Make sure that you put the signingConfigs parts inside the android section:
android
{
....
signingConfigs {
release {
...
}
}
}
instead of
android
{
....
}
signingConfigs {
release {
...
}
}
It is easy to make this mistake.
You're looking for the JavaScriptSerializer
class, which is used internally by JsonResult:
string json = new JavaScriptSerializer().Serialize(jsonResult.Data);
Not with a regular statement, no.
What you can do is wrap the functionality in a PL/pgsql function (or another language, but PL/pgsql seems to be the most appropriate for this), and then just call that function. That means it'll still be a single statement to your app.
Using jQuery the easiest will be:
var text = '<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>';
var output = $("<div />").html(text).text();
console.log(output);
Let me list a use case below. Hope it helps. Here I'm trying to find the Table Owner of the Table 'Stud_dtls' from the DB 'Students'. As Mikael mentioned, sysname could be used when there is a need for creating some dynamic sql which needs variables holding table names, column names and server names. Just thought of providing a simple example to supplement his point.
USE Students
DECLARE @TABLE_NAME sysname
SELECT @TABLE_NAME = 'Stud_dtls'
SELECT TABLE_SCHEMA
FROM INFORMATION_SCHEMA.Tables
WHERE TABLE_NAME = @TABLE_NAME
You can use trimLeft()
and trimRight()
also.
const str1 = " string ";
console.log(str1.trimLeft());
// => "string "
const str2 = " string ";
console.log(str2.trimRight());
// => " string"
write() only takes a single string argument, so you could do this:
outf.write(str(num))
or
outf.write('{}'.format(num)) # more "modern"
outf.write('%d' % num) # deprecated mostly
Also note that write
will not append a newline to your output so if you need it you'll have to supply it yourself.
Aside:
Using string formatting would give you more control over your output, so for instance you could write (both of these are equivalent):
num = 7
outf.write('{:03d}\n'.format(num))
num = 12
outf.write('%03d\n' % num)
to get three spaces, with leading zeros for your integer value followed by a newline:
007
012
format() will be around for a long while, so it's worth learning/knowing.
if work need to be done with formatted text with out html encoding.
it can be easy achieved with following scenario that creates div element on the fly and using <pre></pre>
html element to keep formatting.
var email_body = htmlEncode($("#Body").val());
function htmlEncode(value) {
return "<pre>" + $('<div/>').text(value).html() + "</pre>";
}
enum Orientations
{
None, North, East, South, West
}
private Orientations? _orientation { get; set; }
public Orientations? Orientation
{
get
{
return _orientation ?? Orientations.None;
}
set
{
_orientation = value;
}
}
If you set the property to null will return Orientations.None on get. The property _orientation is null by default.
Both methods ensure that your process doesn't end before all of your threads have ended.
The join method has your thread of the main
function explicitly wait for all threads that are to be "joined".
The pthread_exit
method terminates your main
function and thread in a controlled way. main
has the particularity that ending main
otherwise would be terminating your whole process including all other threads.
For this to work, you have to be sure that none of your threads is using local variables that are declared inside them main
function. The advantage of that method is that your main
doesn't have to know all threads that have been started in your process, e.g because other threads have themselves created new threads that main
doesn't know anything about.
I faced this problem while working in a spring project with tomcat:
Address already in use: JVM_Bind
To resolve the issue I ran a shutdown.bat file in tomcat/bin folder.
WSDL: Stands for Web Service Description Language
In SOAP(simple object access protocol), when you use web service and add a web service to your project, your client application(s) doesn't know about web service Functions. Nowadays it's somehow old-fashion and for each kind of different client you have to implement different WSDL
files. For example you cannot use same file for .Net
and php
client.
The WSDL
file has some descriptions about web service functions. The type of this file is XML
. SOAP
is an alternative for REST
.
REST: Stands for Representational State Transfer
It is another kind of API service, it is really easy to use for clients. They do not need to have special file extension like WSDL
files. The CRUD operation can be implemented by different HTTP Verbs
(GET for Reading, POST for Creation, PUT or PATCH for Updating and DELETE for Deleting the desired document) , They are based on HTTP
protocol and most of times the response is in JSON
or XML
format. On the other hand the client application have to exactly call the related HTTP Verb
via exact parameters names and types. Due to not having special file for definition, like WSDL
, it is a manually job using the endpoint. But it is not a big deal because now we have a lot of plugins for different IDEs to generating the client-side implementation.
SOA: Stands for Service Oriented Architecture
Includes all of the programming with web services concepts and architecture. Imagine that you want to implement a large-scale application. One practice can be having some different services, called micro-services and the whole application mechanism would be calling needed web service at the right time.
Both REST
and SOAP
web services are kind of SOA
.
JSON: Stands for javascript Object Notation
when you serialize an object for javascript the type of object format is JSON. imagine that you have the human class :
class Human{
string Name;
string Family;
int Age;
}
and you have some instances from this class :
Human h1 = new Human(){
Name='Saman',
Family='Gholami',
Age=26
}
when you serialize the h1 object to JSON the result is :
[h1:{Name:'saman',Family:'Gholami',Age:'26'}, ...]
javascript
can evaluate this format by eval()
function and make an associative array from this JSON
string. This one is different concept in comparison to other concepts I described formerly.
5 Jan 2021: link update thanks to @Sadap's comment.
Kind of a corollary answer: the people on this site have taken the time to make tables of macros defined for every OS/compiler pair.
For example, you can see that _WIN32
is NOT defined on Windows with Cygwin (POSIX), while it IS defined for compilation on Windows, Cygwin (non-POSIX), and MinGW with every available compiler (Clang, GNU, Intel, etc.).
Anyway, I found the tables quite informative and thought I'd share here.
Just give full path to exclusion file: eg..
-- no - - - - -xcopy c:\t1 c:\t2 /EXCLUDE:list-of-excluded-files.txt
correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\list-of-excluded-files.txt
In this example the file would be located " C:\list-of-excluded-files.txt "
or...
correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\mybatch\list-of-excluded-files.txt
In this example the file would be located " C:\mybatch\list-of-excluded-files.txt "
Full path fixes syntax error.

128M == 134217728
, the number you are seeing.
The memory limit is working fine. When it says it tried to allocate 32 bytes, that the amount requested by the last operation before failing.
Are you building any huge arrays or reading large text files? If so, remember to free any memory you don't need anymore, or break the task down into smaller steps.
I recommend WinDirStat.
I frequently use WinDirStat to create screen shots for user documentation of open folders and their contents.
It even uses the correct icons for Windows registered file types.
All I would say is missing is an option to display the files without their icons. I can live without it personally, since I am usually pasting the image into a paint program or Visio to edit it, but it would still be a useful feature.
Also as suggested in this blog one can reopen sys.stdout
in unbuffered mode:
sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0)
Each stdout.write
and print
operation will be automatically flushed afterwards.
I use the following approach by combining this and this answer without using exception based programming and also supports pre-API 21 intent flag.
@SuppressWarnings("deprecation")
private Intent getRateIntent()
{
String url = isMarketAppInstalled() ? "market://details" : "https://play.google.com/store/apps/details";
Intent rateIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(String.format("%s?id=%s", url, getPackageName())));
int intentFlags = Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_MULTIPLE_TASK;
intentFlags |= Build.VERSION.SDK_INT >= 21 ? Intent.FLAG_ACTIVITY_NEW_DOCUMENT : Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET;
rateIntent.addFlags(intentFlags);
return rateIntent;
}
private boolean isMarketAppInstalled()
{
Intent marketIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://search?q=anyText"));
return getPackageManager().queryIntentActivities(marketIntent, 0).size() > 0;
}
// use
startActivity(getRateIntent());
Since the intent flag FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET
is deprecated from API 21 I use the @SuppressWarnings("deprecation")
tag on the getRateIntent method because my app target SDK is below API 21.
I also tried the official Google way suggested on their website (Dec. 6th 2019). To what I see it doesn't handle the case if the Play Store app isn't installed:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(
"https://play.google.com/store/apps/details?id=com.example.android"));
intent.setPackage("com.android.vending");
startActivity(intent);
This works: (thanks to the comments)
setTimeout(() =>
{
this.router.navigate(['/']);
},
5000);
If you create a new (not yet implemented) function in NetBeans, then it generates a method body with the following statement:
throw new java.lang.UnsupportedOperationException("Not supported yet.");
Therefore, I recommend to use the UnsupportedOperationException.
import os def parent_directory(): # Create a relative path to the parent # of the current working directory path = os.getcwd() parent = os.path.dirname(path)
relative_parent = os.path.join(path, parent) # Return the absolute path of the parent directory return relative_parent
print(parent_directory())
ALLOW-FROM is not supported in Chrome or Safari. See MDN article: https://developer.mozilla.org/en-US/docs/Web/HTTP/X-Frame-Options
You are already doing the work to make a custom header and send it with the correct data, can you not just exclude the header when you detect it is from a valid partner and add DENY to every other request? I don't see the benefit of AllowFrom when you are already dynamically building the logic up?
if your button is inside your form class:
buttonOk.Click += new EventHandler(your_click_method);
(might not be exactly EventHandler
)
and in your click method:
this.Close();
If you need to show a message box:
MessageBox.Show("test");
I was also looking for some answer. Here all answers are quite good, but none of them give answers how we can use it if user starts application after opening it back. (I meant to say using cookie together).
No need to create even different privateRoute Component. Below is my code
import React, { Component } from 'react';
import { Route, Switch, BrowserRouter, Redirect } from 'react-router-dom';
import { Provider } from 'react-redux';
import store from './stores';
import requireAuth from './components/authentication/authComponent'
import SearchComponent from './components/search/searchComponent'
import LoginComponent from './components/login/loginComponent'
import ExampleContainer from './containers/ExampleContainer'
class App extends Component {
state = {
auth: true
}
componentDidMount() {
if ( ! Cookies.get('auth')) {
this.setState({auth:false });
}
}
render() {
return (
<Provider store={store}>
<BrowserRouter>
<Switch>
<Route exact path="/searchComponent" component={requireAuth(SearchComponent)} />
<Route exact path="/login" component={LoginComponent} />
<Route exact path="/" component={requireAuth(ExampleContainer)} />
{!this.state.auth && <Redirect push to="/login"/> }
</Switch>
</BrowserRouter>
</Provider>);
}
}
}
export default App;
And here is authComponent
import React from 'react';
import { withRouter } from 'react-router';
import * as Cookie from "js-cookie";
export default function requireAuth(Component) {
class AuthenticatedComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
auth: Cookie.get('auth')
}
}
componentDidMount() {
this.checkAuth();
}
checkAuth() {
const location = this.props.location;
const redirect = location.pathname + location.search;
if ( ! Cookie.get('auth')) {
this.props.history.push(`/login?redirect=${redirect}`);
}
}
render() {
return Cookie.get('auth')
? <Component { ...this.props } />
: null;
}
}
return withRouter(AuthenticatedComponent)
}
Below I have written blog, you can get more depth explanation there as well.
Per the docs:
Mac OS X
- Download Visual Studio Code for Mac OS X.
- Double-click on VSCode-osx.zip to expand the contents.
- Drag Visual Studio Code.app to the Applications folder, making it available in the Launchpad.
- Add VS Code to your Dock by right-clicking on the icon and choosing Options, Keep in Dock.
Tip: If you want to run VS Code from the terminal, append the following to your ~/.bash_profile file (~/.zshrc in case you use zsh).
code () { VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* ;}
Now, you can simply type code . in any folder to start editing files in that folder.
Tip: You can also add it to VS Code Insiders build by changing "com.microsoft.VSCodeInsiders". Also if you don't to type the whole word code, just change it to c.
Linux
- Download Visual Studio Code for Linux.
- Make a new folder and extract VSCode-linux-x64.zip inside that folder.
- Double click on Code to run Visual Studio Code.
Tip: If you want to run VS Code from the terminal, create the following link substituting /path/to/vscode/Code with the absolute path to the Code executable
sudo ln -s /path/to/vscode/Code /usr/local/bin/code
Now, you can simply type code . in any folder to start editing files in that folder.
Here's how I do it, the keys are getItemViewType and getViewTypeCount in the Adapter
class. getViewTypeCount
returns how many types of items we have in the list, in this case we have a header item and an event item, so two. getItemViewType
should return what type of View
we have at the input position
.
Android will then take care of passing you the right type of View
in convertView
automatically.
Here what the result of the code below looks like:
First we have an interface that our two list item types will implement
public interface Item {
public int getViewType();
public View getView(LayoutInflater inflater, View convertView);
}
Then we have an adapter that takes a list of Item
public class TwoTextArrayAdapter extends ArrayAdapter<Item> {
private LayoutInflater mInflater;
public enum RowType {
LIST_ITEM, HEADER_ITEM
}
public TwoTextArrayAdapter(Context context, List<Item> items) {
super(context, 0, items);
mInflater = LayoutInflater.from(context);
}
@Override
public int getViewTypeCount() {
return RowType.values().length;
}
@Override
public int getItemViewType(int position) {
return getItem(position).getViewType();
}
@Override public View getView(int position, View convertView, ViewGroup parent) { return getItem(position).getView(mInflater, convertView); }
EDIT Better For Performance.. can be noticed when scrolling
private static final int TYPE_ITEM = 0;
private static final int TYPE_SEPARATOR = 1;
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
int rowType = getItemViewType(position);
View View;
if (convertView == null) {
holder = new ViewHolder();
switch (rowType) {
case TYPE_ITEM:
convertView = mInflater.inflate(R.layout.task_details_row, null);
holder.View=getItem(position).getView(mInflater, convertView);
break;
case TYPE_SEPARATOR:
convertView = mInflater.inflate(R.layout.task_detail_header, null);
holder.View=getItem(position).getView(mInflater, convertView);
break;
}
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
return convertView;
}
public static class ViewHolder {
public View View; }
}
Then we have classes the implement Item
and inflate the correct layouts. In your case you'll have something like a Header
class and a ListItem
class.
public class Header implements Item {
private final String name;
public Header(String name) {
this.name = name;
}
@Override
public int getViewType() {
return RowType.HEADER_ITEM.ordinal();
}
@Override
public View getView(LayoutInflater inflater, View convertView) {
View view;
if (convertView == null) {
view = (View) inflater.inflate(R.layout.header, null);
// Do some initialization
} else {
view = convertView;
}
TextView text = (TextView) view.findViewById(R.id.separator);
text.setText(name);
return view;
}
}
And then the ListItem
class
public class ListItem implements Item {
private final String str1;
private final String str2;
public ListItem(String text1, String text2) {
this.str1 = text1;
this.str2 = text2;
}
@Override
public int getViewType() {
return RowType.LIST_ITEM.ordinal();
}
@Override
public View getView(LayoutInflater inflater, View convertView) {
View view;
if (convertView == null) {
view = (View) inflater.inflate(R.layout.my_list_item, null);
// Do some initialization
} else {
view = convertView;
}
TextView text1 = (TextView) view.findViewById(R.id.list_content1);
TextView text2 = (TextView) view.findViewById(R.id.list_content2);
text1.setText(str1);
text2.setText(str2);
return view;
}
}
And a simple Activity
to display it
public class MainActivity extends ListActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
List<Item> items = new ArrayList<Item>();
items.add(new Header("Header 1"));
items.add(new ListItem("Text 1", "Rabble rabble"));
items.add(new ListItem("Text 2", "Rabble rabble"));
items.add(new ListItem("Text 3", "Rabble rabble"));
items.add(new ListItem("Text 4", "Rabble rabble"));
items.add(new Header("Header 2"));

You can also get fancier and use ViewHolders
, load stuff asynchronously, or whatever you like.
You can use arguments with default values.
def someMethod(def mandatory,def optional=null){}
if argument "optional" not exist, it turns to "null".
The below code works for me, for both accessing and changing a pixel value.
For accessing pixel's channel value :
for (int i = 0; i < image.cols; i++) {
for (int j = 0; j < image.rows; j++) {
Vec3b intensity = image.at<Vec3b>(j, i);
for(int k = 0; k < image.channels(); k++) {
uchar col = intensity.val[k];
}
}
}
For changing a pixel value of a channel :
uchar pixValue;
for (int i = 0; i < image.cols; i++) {
for (int j = 0; j < image.rows; j++) {
Vec3b &intensity = image.at<Vec3b>(j, i);
for(int k = 0; k < image.channels(); k++) {
// calculate pixValue
intensity.val[k] = pixValue;
}
}
}

Below connection string is working
import pandas as pd
import pyodbc as odbc
sql_conn = odbc.connect('DRIVER={ODBC Driver 13 for SQL Server};SERVER=SERVER_NAME;DATABASE=DATABASE_NAME;UID=USERNAME;PWD=PASSWORD;')

Here's a compact way to do something different in all four cases:
if(empty($youtube)) {
if(empty($link)) {
# both empty
} else {
# only $youtube not empty
}
} else {
if(empty($link)) {
# only $link empty
} else {
# both not empty
}
}
If you want to use an expression instead, you can use ?:
instead:
echo empty($youtube) ? ( empty($link) ? 'both empty' : 'only $youtube not empty' )
: ( empty($link) ? 'only $link empty' : 'both not empty' );
Well, both are very, very very very misunderstood and also two completely different things. that aren't mutually exclusive.
Static types are a restriction of the grammar of the language. Statically typed languages strictly could be said to not be context free. The simple truth is that it becomes inconvenient to express a language sanely in context free grammars that doesn't treat all its data simply as bit vectors. Static type systems are part of the grammar of the language if any, they simply restrict it more than a context free grammar could, grammatical checks thus happen in two passes over the source really. Static types correspond to the mathematical notion of type theory, type theory in mathematics simply restricts the legality of some expressions. Like, I can't say 3 + [4,7]
in maths, this is because of the type theory of it.
Static types are thus not a way to 'prevent errors' from a theoretical perspective, they are a limitation of the grammar. Indeed, provided that +, 3 and intervals have the usual set theoretical definitions, if we remove the type system 3 + [4,7]
has a pretty well defined result that's a set. 'runtime type errors' theoretically do not exist, the type system's practical use is to prevent operations that to human beings would make no sense. Operations are still just the shifting and manipulation of bits of course.
The catch to this is that a type system can't decide if such operations are going to occur or not if it would be allowed to run. As in, exactly partition the set of all possible programs in those that are going to have a 'type error', and those that aren't. It can do only two things:
1: prove that type errors are going to occur in a program
2: prove that they aren't going to occur in a program
This might seem like I'm contradicting myself. But what a C or Java type checker does is it rejects a program as 'ungrammatical', or as it calls it 'type error' if it can't succeed at 2. It can't prove they aren't going to occur, that doesn't mean that they aren't going to occur, it just means it can't prove it. It might very well be that a program which will not have a type error is rejected simply because it can't be proven by the compiler. A simple example being if(1) a = 3; else a = "string";
, surely since it's always true, the else-branch will never be executed in the program, and no type error shall occur. But it can't prove these cases in a general way, so it's rejected. This is the major weakness of a lot of statically typed languages, in protecting you against yourself, you're necessarily also protected in cases you don't need it.
But, contrary to popular believe, there are also statically typed languages that work by principle 1. They simply reject all programs of which they can prove it's going to cause a type error, and pass all programs of which they can't. So it's possible they allow programs which have type errors in them, a good example being Typed Racket, it's hybrid between dynamic and static typing. And some would argue that you get the best of both worlds in this system.
Another advantage of static typing is that types are known at compile time, and thus the compiler can use this. If we in Java do "string" + "string"
or 3 + 3
, both +
tokens in text in the end represent a completely different operation and datum, the compiler knows which to choose from the types alone.
Now, I'm going to make a very controversial statement here but bear with me: 'dynamic typing' does not exist.
Sounds very controversial, but it's true, dynamically typed languages are from a theoretical perspective untyped. They are just statically typed languages with only one type. Or simply put, they are languages that are indeed grammatically generated by a context free grammar in practice.
Why don't they have types? Because every operation is defined and allowed on every operant, what's a 'runtime type error' exactly? It's from a theoretical example purely a side-effect. If doing print("string")
which prints a string is an operation, then so is length(3)
, the former has the side effect of writing string
to the standard output, the latter simply error: function 'length' expects array as argument.
, that's it. There is from a theoretical perspective no such thing as a dynamically typed language. They are untyped
All right, the obvious advantage of 'dynamically typed' language is expressive power, a type system is nothing but a limitation of expressive power. And in general, languages with a type system indeed would have a defined result for all those operations that are not allowed if the type system was just ignored, the results would just not make sense to humans. Many languages lose their Turing completeness after applying a type system.
The obvious disadvantage is the fact that operations can occur which would produce results which are nonsensical to humans. To guard against this, dynamically typed languages typically redefine those operations, rather than producing that nonsensical result they redefine it to having the side effect of writing out an error, and possibly halting the program altogether. This is not an 'error' at all, in fact, the language specification usually implies this, this is as much behaviour of the language as printing a string from a theoretical perspective. Type systems thus force the programmer to reason about the flow of the code to make sure that this doesn't happen. Or indeed, reason so that it does happen can also be handy in some points for debugging, showing that it's not an 'error' at all but a well defined property of the language. In effect, the single remnant of 'dynamic typing' that most languages have is guarding against a division by zero. This is what dynamic typing is, there are no types, there are no more types than that zero is a different type than all the other numbers. What people call a 'type' is just another property of a datum, like the length of an array, or the first character of a string. And many dynamically typed languages also allow you to write out things like "error: the first character of this string should be a 'z'"
.
Another thing is that dynamically typed languages have the type available at runtime and usually can check it and deal with it and decide from it. Of course, in theory it's no different than accessing the first char of an array and seeing what it is. In fact, you can make your own dynamic C, just use only one type like long long int and use the first 8 bits of it to store your 'type' in and write functions accordingly that check for it and perform float or integer addition. You have a statically typed language with one type, or a dynamic language.
In practise this all shows, statically typed languages are generally used in the context of writing commercial software, whereas dynamically typed languages tend to be used in the context of solving some problems and automating some tasks. Writing code in statically typed languages simply takes long and is cumbersome because you can't do things which you know are going to turn out okay but the type system still protects you against yourself for errors you don't make. Many coders don't even realize that they do this because it's in their system but when you code in static languages, you often work around the fact that the type system won't let you do things that can't go wrong, because it can't prove it won't go wrong.
As I noted, 'statically typed' in general means case 2, guilty until proven innocent. But some languages, which do not derive their type system from type theory at all use rule 1: Innocent until proven guilty, which might be the ideal hybrid. So, maybe Typed Racket is for you.
Also, well, for a more absurd and extreme example, I'm currently implementing a language where 'types' are truly the first character of an array, they are data, data of the 'type', 'type', which is itself a type and datum, the only datum which has itself as a type. Types are not finite or bounded statically but new types may be generated based on runtime information.

To answer TJJ: But is it also possible to do this without copying the whole file? So, just to somehow create an additional vmdk-metafile, that references the raw dd-image.
Yes, it's possible. Here's how to use a flat disk image in VirtualBox:
First you create an image with dd in the usual way:
dd bs=512 count=60000 if=/dev/zero of=usbdrv.img
Then you can create a file for VirtualBox that references this image:
VBoxManage internalcommands createrawvmdk -filename "usbdrv.vmdk" -rawdisk "usbdrv.img"
You can use this image in VirtualBox as is, but depending on the guest OS it might not be visible immediately. For example, I experimented on using this method with a Windows guest OS and I had to do the following to give it a drive letter:
You might want to access your files on Linux. First dismount it from the guest OS to be sure and remove it from the virtual machine. Now we need to create a virtual device that references the partition.
sfdisk -d usbdrv.img
Response:
label: dos
label-id: 0xd367a714
device: usbdrv.img
unit: sectors
usbdrv.img1 : start= 63, size= 48132, type=4
Take note of the start position of the partition: 63. In the command below I used loop4 because it was the first available loop device in my case.
sudo losetup -o $((63*512)) loop4 usbdrv.img
mkdir usbdrv
sudo mount /dev/loop4 usbdrv
ls usbdrv -l
Response:
total 0
-rwxr-xr-x. 1 root root 0 Apr 5 17:13 'Test file.txt'
Yay!
Another way to do this is to add the new characters to the string as follows:
Dim str As String
str = ""
To append text to your string this way:
str = str & "and this is more text"
i have used below method to give me md5 by passing string for which you want to get md5
public static String getMd5Key(String password) {
// String password = "12131123984335";
try {
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(password.getBytes());
byte byteData[] = md.digest();
//convert the byte to hex format method 1
StringBuffer sb = new StringBuffer();
for (int i = 0; i < byteData.length; i++) {
sb.append(Integer.toString((byteData[i] & 0xff) + 0x100, 16).substring(1));
}
System.out.println("Digest(in hex format):: " + sb.toString());
//convert the byte to hex format method 2
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < byteData.length; i++) {
String hex = Integer.toHexString(0xff & byteData[i]);
if (hex.length() == 1) hexString.append('0');
hexString.append(hex);
}
System.out.println("Digest(in hex format):: " + hexString.toString());
return hexString.toString();
} catch (Exception e) {
// TODO: handle exception
}
return "";
}
You can stash
(save the changes in temporary box) then, back to master
branch HEAD.
$ git add .
$ git stash
$ git checkout master
Jump Over Commits Back and Forth:
Go to a specific commit-sha
.
$ git checkout <commit-sha>
If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.
# checkout a new branch, add, commit, push
$ git checkout -b <branch-name>
$ git add .
$ git commit -m 'Commit message'
$ git push origin HEAD # push the current branch to remote
$ git checkout master # back to master branch now
If you have changes in the specific commit and don't want to keep the changes, you can do stash
or reset
then checkout to master
(or, any other branch).
# stash
$ git add -A
$ git stash
$ git checkout master
# reset
$ git reset --hard HEAD
$ git checkout master
After checking out a specific commit if you have no uncommitted change(s) then, just back to master
or other
branch.
$ git status # see the changes
$ git checkout master
# or, shortcut
$ git checkout - # back to the previous state

This worked for me on OS X: (I say this because sometimes is a pain that mac has "its own" version of every open source tool, and you cannot remove it because "its improvements" make it unique for other apple stuff to work, and if you remove it things start falling appart)
I followed the steps provided by @Lennart Regebro to get pip for python 3, nevertheless pip for python 2 was still first on the path, so... what I did is to create a symbolic link to python 3 inside /usr/bin (in deed I did the same to have my 2 pythons running in peace):
ln -s /Library/Frameworks/Python.framework/Versions/3.4/bin/pip /usr/bin/pip3
Notice that I added a 3
at the end, so basically what you have to do is to use pip3
instead of just pip
.
The post is old but I hope this helps someone someday. this should theoretically work for any LINUX system.
SELECT Id 'PatientId',
ISNULL(CONVERT(varchar(50),ParentId),'') 'ParentId'
FROM Patients
ISNULL
always tries to return a result that has the same data type as the type of its first argument. So, if you want the result to be a string (varchar
), you'd best make sure that's the type of the first argument.
COALESCE
is usually a better function to use than ISNULL
, since it considers all argument data types and applies appropriate precedence rules to determine the final resulting data type. Unfortunately, in this case, uniqueidentifier
has higher precedence than varchar
, so that doesn't help.
(It's also generally preferred because it extends to more than two arguments)

Using Sieve of Eratosthenes logic, I am able to achieve the same results with much faster speed.
My code demo VS accepted answer.
Comparing the count
,
my code takes significantly lesser iteration to finish the job. Checkout the results for different N
values in the end.
Why this code performs better than already accepted ones:
- the even numbers are not checked even once throughout the process.
- both inner and outer loops are checking only within possible limits. No extraneous checks.
Code:
int N = 1000; //Print primes number from 1 to N
vector<bool> primes(N, true);
for(int i = 3; i*i < N; i += 2){ //Jump of 2
for(int j = 3; j*i < N; j+=2){ //Again, jump of 2
primes[j*i] = false;
}
}
if(N >= 2) cout << "2 ";
for(int i = 3; i < N; i+=2){ //Again, jump of 2
if(primes[i] == true) cout << i << " ";
}
For N = 1000
, my code takes 1166 iterations, accepted answer takes 5287 (4.5 times slower)
For N = 10000
, my code takes 14637 iterations, accepted answer takes 117526 (8 times slower)
For N = 100000
, my code takes 175491 iterations, accepted answer takes 2745693 (15.6 times slower)

Building on Peter N's answer, this is an example of how to add (optional) user-specified arguments to pass to Java main for a JavaExec task (since you can't set the 'args' property manually for the reason he cites.)
Add this to the task:

[...]
if (project.hasProperty('myargs')) {
args(myargs.split(','))
}
... and run at the command line like this
% ./gradlew runProgram '-Pmyargs=-x,7,--no-kidding,/Users/rogers/tests/file.txt'

Parent class methods that are static are not part of a child class (although they are accessible), so there is no question of overriding it. Even if you add another static method in a subclass, identical to the one in its parent class, this subclass static method is unique and distinct from the static method in its parent class.
Example code:
a = pd.Series([1,2,3,4], index=[7,2,8,9])
b = pd.Series([5,6,7,8], index=[7,2,8,9])
data = pd.DataFrame({'a': a,'b':b, 'idx_col':a.index})
Pandas allows you to create a DataFrame
from a dict
with Series
as the values and the column names as the keys. When it finds a Series
as a value, it uses the Series
index as part of the DataFrame
index. This data alignment is one of the main perks of Pandas. Consequently, unless you have other needs, the freshly created DataFrame
has duplicated value. In the above example, data['idx_col']
has the same data as data.index
.
You probably want to use "eq" instead of "==". If you worry about some edge cases you may also want to check for undefined:
if (not defined $str) {
# this variable is undefined
}
