We should really stop advising the use of sudo with pip install. It's better to first try pip install --user. If this fails then take a look at the top post here.
The reason you shouldn't use sudo is as follows:
When you run pip with sudo, you are running arbitrary Python code from the Internet as a root user, which is quite a big security risk. If someone puts up a malicious project on PyPI and you install it, you give an attacker root access to your machine.
So here is my solution (similar to John Vance's answer):
First go here and get a function to detect mobile browsers.
http://detectmobilebrowsers.com/
They have a lot of different ways to detect if you are on mobile, so find one that works with what you are using.
Your HTML page (pseudo code):
If Mobile Then
<input id="selling-date" type="date" placeholder="YYYY-MM-DD" max="2999-12-31" min="2010-01-01" value="2015-01-01" />
else
<input id="selling-date" type="text" class="date-picker" readonly="readonly" placeholder="YYYY-MM-DD" max="2999-12-31" min="2010-01-01" value="2015-01-01" />
JQuery:
$( ".date-picker" ).each(function() {
var min = $( this ).attr("min");
var max = $( this ).attr("max");
$( this ).datepicker({
dateFormat: "yy-mm-dd",
minDate: min,
maxDate: max
});
});
This way you can still use native date selectors in mobile while still setting the min and max dates either way.
The field for non mobile should be read only because if a mobile browser like chrome for ios "requests desktop version" then they can get around the mobile check and you still want to prevent the keyboard from showing up.
However if the field is read only it could look to a user like they cant change the field. You could fix this by changing the CSS to make it look like it isn't read only (ie change border-color to black) but unless you are changing the CSS for all input tags you will find it hard to keep the look consistent across browsers.
To get arround that I just add a calendar image button to the date picker. Just change your JQuery code a bit:
$( ".date-picker" ).each(function() {
var min = $( this ).attr("min");
var max = $( this ).attr("max");
$( this ).datepicker({
dateFormat: "yy-mm-dd",
minDate: min,
maxDate: max,
showOn: "both",
buttonImage: "images/calendar.gif",
buttonImageOnly: true,
buttonText: "Select date"
});
});
Note: you will have to find a suitable image.
If you mean an equal number of lines, split has an option for this:
split --lines=75
If you need to know what that 75 should really be for N equal parts, its:
lines_per_part = int(total_lines + N - 1) / N
where total lines can be obtained with wc -l.
See the following script for an example:
#!/usr/bin/bash
# Configuration stuff
fspec=qq.c
num_files=6
# Work out lines per file.
total_lines=$(wc -l <${fspec})
((lines_per_file = (total_lines + num_files - 1) / num_files))
# Split the actual file, maintaining lines.
split --lines=${lines_per_file} ${fspec} xyzzy.
# Debug information
echo "Total lines = ${total_lines}"
echo "Lines per file = ${lines_per_file}"
wc -l xyzzy.*
This outputs:
Total lines = 70
Lines per file = 12
12 xyzzy.aa
12 xyzzy.ab
12 xyzzy.ac
12 xyzzy.ad
12 xyzzy.ae
10 xyzzy.af
70 total
More recent versions of split allow you to specify a number of CHUNKS with the -n/--number option. You can therefore use something like:
split --number=l/6 ${fspec} xyzzy.
(that's ell-slash-six, meaning lines, not one-slash-six).
That will give you roughly equal files in terms of size, with no mid-line splits.
I mention that last point because it doesn't give you roughly the same number of lines in each file, more the same number of characters.
So, if you have one 20-character line and 19 1-character lines (twenty lines in total) and split to five files, you most likely won't get four lines in every file.

After doing some testing, building upon the suggestions in the previous answers, there seem to be two usable solutions.
Method 1 is fastest, but less powerful in terms of matching more complex patterns.
Method 2 is more flexible, but slower.
Method 1 - fastest
I've tested this method on a table with 1 million rows.
It seems to be 3.8 times faster than the regex solutions.
The 0-replacement solves the issue that 0 is mapped to a space, and does not seem to slow down the query.
SELECT *
FROM <table>
WHERE TRANSLATE(replace(<char_column>,'0',''),'0123456789',' ') IS NOT NULL;
Method 2 - slower, but more flexible
I've compared the speed of putting the negation inside or outside the regex statement. Both are equally slower than the translate-solution. As a result, @ciuly's approach seems most sensible when using regex.
SELECT *
FROM <table>
WHERE NOT REGEXP_LIKE(<char_column>, '^[0-9]+$');
This is an old question, but I stumbled across it and thought I'd share the method I used:
var body = '<div id="anid">some <a href="link">text</a></div> and some more text';
var temp = document.createElement("div");
temp.innerHTML = body;
var sanitized = temp.textContent || temp.innerText;
sanitized will now contain: "some text and some more text"
Simple, no jQuery needed, and it shouldn't let you down even in more complex cases.
Only static functions are called with class name.
classname::Staicfunction();
Non static functions have to be called using objects.
classname obj;
obj.Somefunction();
This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.
One way to do this would be to pass the instance of ParentClass to the ChildClass on construction
public ChildClass
{
private ParentClass parent;
public ChildClass(ParentClass parent)
{
this.parent = parent;
}
public void LoadData(DateTable dt)
{
// do something
parent.CurrentRow++; // or whatever.
parent.UpdateProgressBar(); // Call the method
}
}
Make sure to pass the reference to this when constructing ChildClass inside parent:
if(loadData){
ChildClass childClass = new ChildClass(this); // here
childClass.LoadData(this.Datatable);
}
Caveat: This is probably not the best way to organise your classes, but it directly answers your question.
EDIT: In the comments you mention that more than 1 parent class wants to use ChildClass. This is possible with the introduction of an interface, eg:
public interface IParentClass
{
void UpdateProgressBar();
int CurrentRow{get; set;}
}
Now, make sure to implement that interface on both (all?) Parent Classes and change child class to this:
public ChildClass
{
private IParentClass parent;
public ChildClass(IParentClass parent)
{
this.parent = parent;
}
public void LoadData(DateTable dt)
{
// do something
parent.CurrentRow++; // or whatever.
parent.UpdateProgressBar(); // Call the method
}
}
Now anything that implements IParentClass can construct an instance of ChildClass and pass this to its constructor.
It also important to make sure that the web server sends the file with Content-Disposition = inline. this might not be the case if you are reading the file yourself and send it's content to the browser:
in php it will look like this...
...headers...
header("Content-Disposition: inline; filename=doc.pdf");
...headers...
readfile('localfilepath.pdf')
EDIT: The Numpy project now provides pre-compiled packages in the wheel format (package format enabling compiled code as binary in packages), so the installation is now as easy as with other packages.
Numpy (as also some other packages like Scipy, Pandas etc.) includes lot's of C-, Cython, and Fortran code that needs to be compiled properly, before you can use it. This is, btw, also the reason why these Python-packages provide such fast Linear Algebra.
To get precompiled packages for Windows, have a look at Gohlke's Unofficial Windows Binaries or use a distribution like Winpython (just works) or Anaconda (more complex) which provide an entire preconfigured environment with lots of packages from the scientific python stack.
The code looks unnecessarily complicated. Here is my version:
void strrev(char* str) {
size_t len = strlen(str);
char buf[len];
for (size_t i = 0; i < len; i++) {
buf[i] = str[len - 1 - i];
};
for (size_t i = 0; i < len; i++) {
str[i] = buf[i];
}
}
Try this:
$('#button1').click(function(){
$('#formId').attr('action', 'page1');
});
$('#button2').click(function(){
$('#formId').attr('action', 'page2');
});
Most memory leaks are the result of not being clear about object ownership and lifetime.
The first thing to do is to allocate on the Stack whenever you can. This deals with most of the cases where you need to allocate a single object for some purpose.
If you do need to 'new' an object then most of the time it will have a single obvious owner for the rest of its lifetime. For this situation I tend to use a bunch of collections templates that are designed for 'owning' objects stored in them by pointer. They are implemented with the STL vector and map containers but have some differences:
My beaf with STL is that it is so focused on Value objects while in most applications objects are unique entities that do not have meaningful copy semantics required for use in those containers.
for (var i = 0; i < myVar.length; i+=3) {
//every three
}

Operator Example Same As
++ X ++ x = x + 1
-- X -- x = x - 1
+= x += y x = x + y
-= x -= y x = x - y
*= x *= y x = x * y
/= x /= y x = x / y
%= x %= y x = x % y
You can use -match instead -eq if you also want to exclude files that only contain whitespace characters:
@(gc c:\FileWithEmptyLines.txt) -match '\S' | out-file c:\FileWithNoEmptyLines
A "const function", denoted with the keyword const after a function declaration, makes it a compiler error for this class function to change a member variable of the class. However, reading of a class variables is okay inside of the function, but writing inside of this function will generate a compiler error.
Another way of thinking about such "const function" is by viewing a class function as a normal function taking an implicit this pointer. So a method int Foo::Bar(int random_arg) (without the const at the end) results in a function like int Foo_Bar(Foo* this, int random_arg), and a call such as Foo f; f.Bar(4) will internally correspond to something like Foo f; Foo_Bar(&f, 4). Now adding the const at the end (int Foo::Bar(int random_arg) const) can then be understood as a declaration with a const this pointer: int Foo_Bar(const Foo* this, int random_arg). Since the type of this in such case is const, no modifications of member variables are possible.
It is possible to loosen the "const function" restriction of not allowing the function to write to any variable of a class. To allow some of the variables to be writable even when the function is marked as a "const function", these class variables are marked with the keyword mutable. Thus, if a class variable is marked as mutable, and a "const function" writes to this variable then the code will compile cleanly and the variable is possible to change. (C++11)
As usual when dealing with the const keyword, changing the location of the const key word in a C++ statement has entirely different meanings. The above usage of const only applies when adding const to the end of the function declaration after the parenthesis.
const is a highly overused qualifier in C++: the syntax and ordering is often not straightforward in combination with pointers. Some readings about const correctness and the const keyword:
func NKPlaceholderImage(image:UIImage?, imageView:UIImageView?,imgUrl:String,compate:@escaping (UIImage?) -> Void){
if image != nil && imageView != nil {
imageView!.image = image!
}
var urlcatch = imgUrl.replacingOccurrences(of: "/", with: "#")
let documentpath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
urlcatch = documentpath + "/" + "\(urlcatch)"
let image = UIImage(contentsOfFile:urlcatch)
if image != nil && imageView != nil
{
imageView!.image = image!
compate(image)
}else{
if let url = URL(string: imgUrl){
DispatchQueue.global(qos: .background).async {
() -> Void in
let imgdata = NSData(contentsOf: url)
DispatchQueue.main.async {
() -> Void in
imgdata?.write(toFile: urlcatch, atomically: true)
let image = UIImage(contentsOfFile:urlcatch)
compate(image)
if image != nil {
if imageView != nil {
imageView!.image = image!
}
}
}
}
}
}
}
Use Like this :
// Here imgPicture = your imageView
// UIImage(named: "placeholder") is Display image brfore download and load actual image.
NKPlaceholderImage(image: UIImage(named: "placeholder"), imageView: imgPicture, imgUrl: "Put Here your server image Url Sting") { (image) in }
The answer could be neither or both.
neither: time.time() returns approximately the number of seconds elapsed since the Epoch. The result doesn't depend on timezone so it is neither UTC nor local time. Here's POSIX defintion for "Seconds Since the Epoch".
both: time.time() doesn't require your system's clock to be synchronized so it reflects its value (though it has nothing to do with local timezone). Different computers may get different results at the same time. On the other hand if your computer time is synchronized then it is easy to get UTC time from the timestamp (if we ignore leap seconds):
from datetime import datetime
utc_dt = datetime.utcfromtimestamp(timestamp)
On how to get timestamps from UTC time in various Python versions, see How can I get a date converted to seconds since epoch according to UTC?
I'd prefer to use the .Find method directly on a range object containing the range of cells to be searched. For original poster's code it might look like:
Set cell = ActiveSheet.Columns("B:B").Find( _
What:=celda, _
After:=ActiveCell _
LookIn:=xlFormulas, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlNext, _
MatchCase:=False, _
SearchFormat:=False _
)
If cell Is Nothing Then
'do something
Else
'do something else
End If
I'd prefer to use more variables (and be sure to declare them) and let a lot of optional arguments use their default values:
Dim rng as Range
Dim cell as Range
Dim search as String
Set rng = ActiveSheet.Columns("B:B")
search = "String to Find"
Set cell = rng.Find(What:=search, LookIn:=xlFormulas, LookAt:=xlWhole, MatchCase:=False)
If cell Is Nothing Then
'do something
Else
'do something else
End If
I kept LookIn:=, LookAt::=, and MatchCase:= to be explicit about what is being matched. The other optional parameters control the order matches are returned in - I'd only specify those if the order is important to my application.
Your question shows you have succumbed to some of the common misconceptions surrounding table variables and temporary tables.
I have written quite an extensive answer on the DBA site looking at the differences between the two object types. This also addresses your question about disk vs memory (I didn't see any significant difference in behaviour between the two).
Regarding the question in the title though as to when to use a table variable vs a local temporary table you don't always have a choice. In functions, for example, it is only possible to use a table variable and if you need to write to the table in a child scope then only a #temp table will do
(table-valued parameters allow readonly access).
Where you do have a choice some suggestions are below (though the most reliable method is to simply test both with your specific workload).
If you need an index that cannot be created on a table variable then you will of course need a #temporary table. The details of this are version dependant however. For SQL Server 2012 and below the only indexes that could be created on table variables were those implicitly created through a UNIQUE or PRIMARY KEY constraint. SQL Server 2014 introduced inline index syntax for a subset of the options available in CREATE INDEX. This has been extended since to allow filtered index conditions. Indexes with INCLUDE-d columns or columnstore indexes are still not possible to create on table variables however.
If you will be repeatedly adding and deleting large numbers of rows from the table then use a #temporary table. That supports TRUNCATE (which is more efficient than DELETE for large tables) and additionally subsequent inserts following a TRUNCATE can have better performance than those following a DELETE as illustrated here.
#temporary table. That supports creation of statistics which allows the plan to be dynamically recompiled according to the data (though for cached temporary tables in stored procedures the recompilation behaviour needs to be understood separately).SELECT statement then consider that using a table variable will block the possibility of this using a parallel plan.#temp table within a user transaction locks can be held longer than for table variables (potentially until the end of transaction vs end of statement dependent on the type of lock and isolation level) and also it can prevent truncation of the tempdb transaction log until the user transaction ends. So this might favour the use of table variables.#temporary tables. Bob Ward points out in his tempdb presentation that this can cause additional contention on system tables under conditions of high concurrency. Additionally, when dealing with small quantities of data this can make a measurable difference to performance.Effects of rowset sharing

I looked at most the solutions posted, but came across a different one that I prefer. It's simple, doesn't use threads, and works for what I want it to.
http://weblogs.asp.net/kennykerr/archive/2004/11/26/where-is-form-s-loaded-event.aspx
I added to the solution in the article and moved the code into a base class that all my forms inherit from. Now I just call one function: ShowWaitForm() during the frm_load() event of any form that needs a wait dialogue box while the form is loading. Here's the code:
public class MyFormBase : System.Windows.Forms.Form
{
private MyWaitForm _waitForm;
protected void ShowWaitForm(string message)
{
// don't display more than one wait form at a time
if (_waitForm != null && !_waitForm.IsDisposed)
{
return;
}
_waitForm = new MyWaitForm();
_waitForm.SetMessage(message); // "Loading data. Please wait..."
_waitForm.TopMost = true;
_waitForm.StartPosition = FormStartPosition.CenterScreen;
_waitForm.Show();
_waitForm.Refresh();
// force the wait window to display for at least 700ms so it doesn't just flash on the screen
System.Threading.Thread.Sleep(700);
Application.Idle += OnLoaded;
}
private void OnLoaded(object sender, EventArgs e)
{
Application.Idle -= OnLoaded;
_waitForm.Close();
}
}
MyWaitForm is the name of a form you create to look like a wait dialogue. I added a SetMessage() function to customize the text on the wait form.
Pull to refresh is built in iOS. You could do this in swift like
var refreshControl = UIRefreshControl()
override func viewDidLoad() {
super.viewDidLoad()
refreshControl.attributedTitle = NSAttributedString(string: "Pull to refresh")
refreshControl.addTarget(self, action: #selector(self.refresh(_:)), for: .valueChanged)
tableView.addSubview(refreshControl) // not required when using UITableViewController
}
@objc func refresh(_ sender: AnyObject) {
// Code to refresh table view
}
At some point you could end refreshing.
refreshControl.endRefreshing()
A lot of these answers are pretty old, so I thought I would update with a solution that I think is helpful.
Our issue was similar to OP's, we upgraded 32 bit XP machines to 64 bit windows 7 and our application software that uses a 32 bit ODBC driver stopped being able to write to our database.
Turns out, there are two ODBC Data Source Managers, one for 32 bit and one for 64 bit. So I had to run the 32 bit version which is found in C:\Windows\SysWOW64\odbcad32.exe. Inside the ODBC Data Source Manager, I was able to go to the System DSN tab and Add my driver to the list using the Add button. (You can check the Drivers tab to see a list of the drivers you can add, if your driver isn't in this list then you may need to install it).
The next issue was the software that we ran was compiled to use 'Any CPU'. This would see the operating system was 64 bit, so it would look at the 64 bit ODBC Data Sources. So I had to force the program to compile as an x86 program, which then tells it to look at the 32 bit ODBC Data Sources. To set your program to x86, in Visual Studio go to your project properties and under the build tab at the top there is a platform drop down list, and choose x86. If you don't have the source code and can't compile the program as x86, you might be able to right click the program .exe and go to the compatibility tab and choose a compatibility that works for you.
Once I had the drivers added and the program pointing to the right drivers, everything worked like it use to. Hopefully this helps anyone working with older software.
Make sure to use cascade constraint at the end to automatically drop all objects that depend on the table (such as views and projections).
drop table if exists tableName cascade;
If you want to match a word A in a string and not to match a word B. For example: If you have a text:
1. I have a two pets - dog and a cat
2. I have a pet - dog
If you want to search for lines of text that HAVE a dog for a pet and DOESN'T have cat you can use this regular expression:
^(?=.*?\bdog\b)((?!cat).)*$
It will find only second line:
2. I have a pet - dog

c.AddFunc("@every 1h30m", func() { fmt.Println("Every hour thirty") })

The two syntaxes for stubbing are roughly equivalent. However, you can always use doReturn/when for stubbing; but there are cases where you can't use when/thenReturn. Stubbing void methods is one such. Others include use with Mockito spies, and stubbing the same method more than once.
One thing that when/thenReturn gives you, that doReturn/when doesn't, is type-checking of the value that you're returning, at compile time. However, I believe this is of almost no value - if you've got the type wrong, you'll find out as soon as you run your test.
I strongly recommend only using doReturn/when. There is no point in learning two syntaxes when one will do.
You may wish to refer to my answer at Forming Mockito "grammars" - a more detailed answer to a very closely related question.
what about changing the position: relative on your #content #text div to position: absolute
#content #text {
position:absolute;
width:950px;
height:215px;
color:red;
}
then you can use the css properties left and top to position within the #content div

GitHub for Windows does indeed install its own version of Git, but it doesn't add it to the PATH variable, which is easy enough to do. Here's instructions on how to do it:
Get the Git URL
We need to get the url of the Git \cmd directory your computer. Git is located here:
C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\cmd\git.exe
So on your computer, replace <user> with your user and find out what the <guid> is for your computer. (The guid may change each time GitHub updates PortableGit, but they're working on a solution to that.)
Copy it and paste it into a command prompt (right-click > paste to paste in the terminal) to verify that it works. You should see the Git help response that lists common Git commands. If you see The system cannot find the path specified. Then the URL isn’t right. Once you have it right, create the link to the directory using this format:
;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\cmd
(Note: \cmd at the end, not \cmd\git.exe anymore!)
On my system, it’s this, yours will be different:
;C:\Users\brenton\AppData\Local\GitHub\PortableGit_7eaa494e16ae7b397b2422033as45d8ff6ac2010\cmd
Edit the PATH Variable
Navigate to the Environmental Variables Editor (instructions) and find the Path variable in the “System Variables” section. Click Edit… and paste the URL of Git to the end of that string. Save! It might be easier to pull this into Notepad to do the edit, just make sure you put one semicolon before you paste in the URL. If it doesn't work it’s probably because this path got messed up either with a space in there somewhere (should be no spaces around the semicolon) or a semicolon at the end (semicolons should only separate URLs, no semicolon at beginning or end of string).
If it worked, you should be able to close & reopen a terminal and type git and it will give you that same git help file. Then installing the Linter should work. (Atom > File > Settings > Packages > Linter)
If you do throw an exception from a constructor, keep in mind that you need to use the function try/catch syntax if you need to catch that exception in a constructor initializer list.
e.g.
func::func() : foo()
{
try {...}
catch (...) // will NOT catch exceptions thrown from foo constructor
{ ... }
}
vs.
func::func()
try : foo() {...}
catch (...) // will catch exceptions thrown from foo constructor
{ ... }
Disabled is a Boolean Attribute of the select element as stated by WHATWG, that means the RIGHT WAY TO DISABLE with jQuery would be
jQuery("#selectId").attr('disabled',true);
This would make this HTML
<select id="selectId" name="gender" disabled="disabled">
<option value="-1">--Select a Gender--</option>
<option value="0">Male</option>
<option value="1">Female</option>
</select>
This works for both XHTML and HTML (W3School reference)
Yet it also can be done using it as property
jQuery("#selectId").prop('disabled', 'disabled');
getting
<select id="selectId" name="gender" disabled>
Which only works for HTML and not XTML
NOTE: A disabled element will not be submitted with the form as answered in this question: The disabled form element is not submitted
NOTE2: A disabled element may be greyed out.
NOTE3:
A form control that is disabled must prevent any click events that are queued on the user interaction task source from being dispatched on the element.
<script>
var update_pizza = function () {

$("#pizza").change(update_pizza);
</script>

I got same error after publish my project to my physical server. My web application works perfectly on my computer when I compile on VS2013. When I checked connection string on sql server manager, everything works perfect on server too. I also checked firewall (I switched it off). But still didn't work. I remotely try to connect database by SQL Manager with exactly same user/pass and instance name etc with protocol pipe/tcp and I saw that everything working normally. But when I try to open website I'm getting this error. Is there anyone know 4th option for fix this problem?.
NOTE: My App: ASP.NET 4.5 (by VS2013), Server: Windows 2008 R2 64bit, SQL: MS-SQL WEB 2012 SP1
Also other web applications works great at web browsers with their database on same server.
After one day suffering I found the solution of my issue:
First I checked all the logs and other details but i could find nothing. Suddenly I recognize that; when I try to use connection string which is connecting directly to published DB and run application on my computer by VS2013, I saw that it's connecting another database file. I checked local directories and I found it. ASP.NET Identity not using my connection string as I wrote in web.config file. And because of this VS2013 is creating or connecting a new database with the name "DefaultConnection.mdf" in App_Data folder. Then I found the solution, it was in IdentityModel.cs.
I changed code as this:
public class ApplicationUser : IdentityUser
{
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
//public ApplicationDbContext() : base("DefaultConnection") ---> this was original
public ApplicationDbContext() : base("<myConnectionStringNameInWebConfigFile>") //--> changed
{
}
}
So, after all, I re-builded and published my project and everything works fine now :)
The reason that the compiler lets you cast the object returned from JSON.parse to a class is because typescript is based on structural subtyping.
You don't really have an instance of an Employee, you have an object (as you see in the console) which has the same properties.
A simpler example:
class A {
constructor(public str: string, public num: number) {}
}
function logA(a: A) {
console.log(`A instance with str: "${ a.str }" and num: ${ a.num }`);
}
let a1 = { str: "string", num: 0, boo: true };
let a2 = new A("stirng", 0);
logA(a1); // no errors
logA(a2);
There's no error because a1 satisfies type A because it has all of its properties, and the logA function can be called with no runtime errors even if what it receives isn't an instance of A as long as it has the same properties.
That works great when your classes are simple data objects and have no methods, but once you introduce methods then things tend to break:
class A {
constructor(public str: string, public num: number) { }
multiplyBy(x: number): number {
return this.num * x;
}
}
// this won't compile:
let a1 = { str: "string", num: 0, boo: true } as A; // Error: Type '{ str: string; num: number; boo: boolean; }' cannot be converted to type 'A'
// but this will:
let a2 = { str: "string", num: 0 } as A;
// and then you get a runtime error:
a2.multiplyBy(4); // Error: Uncaught TypeError: a2.multiplyBy is not a function
This works just fine:
const employeeString = '{"department":"<anystring>","typeOfEmployee":"<anystring>","firstname":"<anystring>","lastname":"<anystring>","birthdate":"<anydate>","maxWorkHours":0,"username":"<anystring>","permissions":"<anystring>","lastUpdate":"<anydate>"}';
let employee1 = JSON.parse(employeeString);
console.log(employee1);
If you're trying to use JSON.parse on your object when it's not a string:
let e = {
"department": "<anystring>",
"typeOfEmployee": "<anystring>",
"firstname": "<anystring>",
"lastname": "<anystring>",
"birthdate": "<anydate>",
"maxWorkHours": 3,
"username": "<anystring>",
"permissions": "<anystring>",
"lastUpdate": "<anydate>"
}
let employee2 = JSON.parse(e);
Then you'll get the error because it's not a string, it's an object, and if you already have it in this form then there's no need to use JSON.parse.
But, as I wrote, if you're going with this way then you won't have an instance of the class, just an object that has the same properties as the class members.
If you want an instance then:
let e = new Employee();
Object.assign(e, {
"department": "<anystring>",
"typeOfEmployee": "<anystring>",
"firstname": "<anystring>",
"lastname": "<anystring>",
"birthdate": "<anydate>",
"maxWorkHours": 3,
"username": "<anystring>",
"permissions": "<anystring>",
"lastUpdate": "<anydate>"
});
Try width: max-content to adjust the width of the div by it's content.
<!DOCTYPE html>
<html>
<head>
<style>
div.ex1 {
width:500px;
margin: auto;
border: 3px solid #73AD21;
}
div.ex2 {
width: max-content;
margin: auto;
border: 3px solid #73AD21;
}
</style>
</head>
<body>
<div class="ex1">This div element has width 500px;</div>
<br>
<div class="ex2">Width by content size</div>
</body>
</html>
There isn't a need for _.map or _.pluck since ES6 has taken off.
Here's an alternative using ES6 JavaScript:
clips.map(clip => clip.id)
Since you input field is a controlled element, you cannot directly change the input field value without modifying the state.
Also in
onHandleSubmit(e) {
e.preventDefault();
const city = this.state.city;
this.props.onSearchTermChange(city);
this.mainInput.value = "";
}
this.mainInput doesn't refer the input since mainInput is an id, you need to specify a ref to the input
<input
ref={(ref) => this.mainInput= ref}
onChange={this.onHandleChange}
placeholder="Get current weather..."
value={this.state.city}
type="text"
/>
In you current state the best way is to clear the state to clear the input value
onHandleSubmit(e) {
e.preventDefault();
const city = this.state.city;
this.props.onSearchTermChange(city);
this.setState({city: ""});
}
However if you still for some reason want to keep the value in state even if the form is submitted, you would rather make the input uncontrolled
<input
id="mainInput"
onChange={this.onHandleChange}
placeholder="Get current weather..."
type="text"
/>
and update the value in state onChange and onSubmit clear the input using ref
onHandleChange(e) {
this.setState({
city: e.target.value
});
}
onHandleSubmit(e) {
e.preventDefault();
const city = this.state.city;
this.props.onSearchTermChange(city);
this.mainInput.value = "";
}
Having Said that, I don't see any point in keeping the state unchanged, so the first option should be the way to go.
def get_distinct(original_list):
distinct_list = []
for each in original_list:
if each not in distinct_list:
distinct_list.append(each)
return distinct_list
Try this
Actions dragger = new Actions(driver);
WebElement draggablePartOfScrollbar = driver.findElement(By.xpath("//*[@id='jobreslist_outercontainer']/div/div[2]/div"));
// drag downwards
int numberOfPixelsToDragTheScrollbarDown = 50;
for (int i=10;i<500;i=i+numberOfPixelsToDragTheScrollbarDown){
try{
// this causes a gradual drag of the scroll bar, 10 units at a time
dragger.moveToElement(draggablePartOfScrollbar).clickAndHold().moveByOffset(0,numberOfPixelsToDragTheScrollbarDown).release().perform();
Thread.sleep(1000L);
}catch(Exception e1){}
}
// now drag opposite way (downwards)
numberOfPixelsToDragTheScrollbarDown = -50;
for (int i=500;i>10;i=i+numberOfPixelsToDragTheScrollbarDown){
// this causes a gradual drag of the scroll bar, -10 units at a time
dragger.moveToElement(draggablePartOfScrollbar).clickAndHold().moveByOffset(0,numberOfPixelsToDragTheScrollbarDown).release().perform();
Thread.sleep(1000L);
}
Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".
>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World
Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.
This is a derivite of previous post, but this gets the latest version of the .net framework 4 in my tests.
get-itemproperty -name version,release "hklm:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\FULL"
Which will allow you to invoke-command to remote machine:
invoke-command -computername server01 -scriptblock {get-itemproperty -name version,release "hklm:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\FULL" | select pscomputername,version,release}
Which sets up this possibility with ADModule and naming convention prefix:
get-adcomputer -Filter 'name -like "*prefix*"' | % {invoke-command -computername $_.name -scriptblock {get-itemproperty -name version,release "hklm:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\FULL" | select pscomputername,version,release} | ft
HashSet is O(1) to access elements, so it certainly does matter. But maintaining order of the objects in the set isn't possible.
TreeSet is useful if maintaining an order(In terms of values and not the insertion order) matters to you. But, as you've noted, you're trading order for slower time to access an element: O(log n) for basic operations.
From the javadocs for TreeSet:
This implementation provides guaranteed log(n) time cost for the basic operations (
add,removeandcontains).
To check if a file doesn't exist, equivalent to Python's if not os.path.exists(filename):
if _, err := os.Stat("/path/to/whatever"); os.IsNotExist(err) {
// path/to/whatever does not exist
}
To check if a file exists, equivalent to Python's if os.path.exists(filename):
Edited: per recent comments
if _, err := os.Stat("/path/to/whatever"); err == nil {
// path/to/whatever exists
} else if os.IsNotExist(err) {
// path/to/whatever does *not* exist
} else {
// Schrodinger: file may or may not exist. See err for details.
// Therefore, do *NOT* use !os.IsNotExist(err) to test for file existence
}
You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:
https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899
In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.
You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:
function buildUrls() {
var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1"); // Email, Name, Birthday
var data = ss.getDataRange().getValues();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
var url = template.replace('##Name##',escape(data[i][1]))
.replace('##Birthday##',data[i][2].yyyymmdd()); // see yyyymmdd below
Logger.log(url); // You could do something more useful here.
}
};
This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.
Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.
Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.
We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.
(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)
/**
* Use Form API to generate pre-filled form URLs
*/
function betterBuildUrls() {
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName("Sheet1");
var data = ss.getDataRange().getValues(); // Data for pre-fill
var formUrl = ss.getFormUrl(); // Use form attached to sheet
var form = FormApp.openByUrl(formUrl);
var items = form.getItems();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
// Create a form response object, and prefill it
var formResponse = form.createResponse();
// Prefill Name
var formItem = items[0].asTextItem();
var response = formItem.createResponse(data[i][1]);
formResponse.withItemResponse(response);
// Prefill Birthday
formItem = items[1].asDateItem();
response = formItem.createResponse(data[i][2]);
formResponse.withItemResponse(response);
// Get prefilled form URL
var url = formResponse.toPrefilledUrl();
Logger.log(url); // You could do something more useful here.
}
};
Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.
When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)
// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};
You will need to create a public/private key as the Jenkins user on your Jenkins server, then copy the public key to the user you want to do the deployment with on your target server.
Step 1, generate public and private key on build server as user jenkins
build1:~ jenkins$ whoami
jenkins
build1:~ jenkins$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa):
Created directory '/var/lib/jenkins/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /var/lib/jenkins/.ssh/id_rsa.
Your public key has been saved in /var/lib/jenkins/.ssh/id_rsa.pub.
The key fingerprint is:
[...]
The key's randomart image is:
[...]
build1:~ jenkins$ ls -l .ssh
total 2
-rw------- 1 jenkins jenkins 1679 Feb 28 11:55 id_rsa
-rw-r--r-- 1 jenkins jenkins 411 Feb 28 11:55 id_rsa.pub
build1:~ jenkins$ cat .ssh/id_rsa.pub
ssh-rsa AAAlskdjfalskdfjaslkdjf... [email protected]
Step 2, paste the pub file contents onto the target server.
target:~ bob$ cd .ssh
target:~ bob$ vi authorized_keys (paste in the stuff which was output above.)
Make sure your .ssh dir has permissoins 700 and your authorized_keys file has permissions 644
Step 3, configure Jenkins
$("#YourElementID").css("display","block");
Edit: or as dave thieben points out in his comment below, you can do this as well:
$("#YourElementID").css({ display: "block" });
mystring = mystring.replace(/["']/g, "");
You can use TIMESTAMPDIFF(unit, datetime_expr1, datetime_expr2) function:
SELECT TIMESTAMPDIFF(YEAR, '1970-02-01', CURDATE()) AS age
getParentFragmentManager().setFragmentResultListener is the 2020 way of doing this. Your only limitation is to use a bundle to pass the data. Check out the docs for more info and examples.
Some other ways
getActivity() and cast it to the shared activity between your fragments, then use it as a bridge to pass the data. This solution is highly not recommended because of the cupelling it requires between the activity and the fragments, but it used to be the popular way of doing this back in the KitKat days...FragmentManager is that it's not limited to Bundles. The downside, however, is that you may run into edge cases bugs where you mess up the activity life cycle and get exceptions like IllegalStateException when the fragment manager is in the middle of saving state or the activity were destroyed. Also, it does not support cross-processing communication.You can't do what I think you're asking to do.
The only privileges you can grant on procedures are EXECUTE and DEBUG.
If you want to allow user B to create a procedure in user A schema, then user B must have the CREATE ANY PROCEDURE privilege. ALTER ANY PROCEDURE and DROP ANY PROCEDURE are the other applicable privileges required to alter or drop user A procedures for user B. All are wide ranging privileges, as it doesn't restrict user B to any particular schema. User B should be highly trusted if granted these privileges.
EDIT:
As Justin mentioned, the way to give execution rights to A for a procedure owned by B:
GRANT EXECUTE ON b.procedure_name TO a;
Try this
<form method="post" id="reg" name="reg" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']);?>"
Works well :)
I'm using xampp and my problem was fixed once i rename:
extension_dir = "ext"
to
extension_dir = "C:\xampp\php\ext"
PS: Don't forget to restart apache after making this change!
You could get the days in the date by using the DAY() function:
dateadd(day, -1, dateadd(month, 1, dateadd(day, 1 - day(date), date)))
For completeness, echo $(__git_ps1), on Linux at least, should give you the name of the current branch surrounded by parentheses.
This may be useful is some scenarios as it is not a Git command (while depending on Git), notably for setting up your Bash command prompt to display the current branch.
For example:
/mnt/c/git/ConsoleApp1 (test-branch)> echo $(__git_ps1)
(test-branch)
/mnt/c/git/ConsoleApp1 (test-branch)> git checkout master
Switched to branch 'master'
/mnt/c/git/ConsoleApp1 (master)> echo $(__git_ps1)
(master)
/mnt/c/git/ConsoleApp1 (master)> cd ..
/mnt/c/git> echo $(__git_ps1)
/mnt/c/git>
The fragment identifier (also known as: Fragment IDs, Anchor Identifiers, Named Anchors) introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.
<a href="http://www.someuri.com/page#fragment">Link to fragment identifier</a>
Syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment the fragment follows the query.
<a href="http://www.someuri.com/page?query=1#fragment">Link to fragment with a query</a>
When a Web browser requests a resource from a Web server, the agent sends the URI to the server, but does not send the fragment. Instead, the agent waits for the server to send the resource, and then the agent (Web browser) processes the resource according to the document type and fragment value.
Named Anchors <a name="fragment"> are deprecated in XHTML 1.0, the ID attribute is the suggested replacement. <div id="fragment"></div>
Use SELECT CONVERT(date, '20140327')
In your case,
SELECT [FIRST_NAME],
[MIDDLE_NAME],
[LAST_NAME],
CONVERT(date, [GRADUATION_DATE])
FROM mydb
The problem is here:
answer = newList.sort()
sort does not return the sorted list; rather, it sorts the list in place.
Use:
answer = sorted(newList)
use SimpleDateFormat to first parse() String to Date and then format() Date to String
CSS3 + jQuery Solution
I wanted a solution that did NOT employ jQuery's fade effect as this causes lag in many mobile devices.
Borrowing from Steve Fenton's answer I have adapted a version of this that fades the image in with the CSS3 transition property and opacity. This also takes into account the problem of browser caching, in which case the image will not show up using CSS.
Here is my code and working fiddle:
HTML
<img src="http://placehold.it/350x150" class="fade-in-on-load">
CSS
.fade-in-on-load {
opacity: 0;
will-change: transition;
transition: opacity .09s ease-out;
}
jQuery Snippet
$(".fade-in-on-load").each(function(){
if (!this.complete) {
$(this).bind("load", function () {
$(this).css('opacity', '1');
});
} else {
$(this).css('opacity', '1');
}
});
What's happening here is the image (or any element) that you want to fade in when it loads will need to have the .fade-in-on-load class applied to it beforehand. This will assign it a 0 opacity and assign the transition effect, you can edit the fade speed to taste in the CSS.
Then the JS will search each item that has the class and bind the load event to it. Once done, the opacity will be set to 1, and the image will fade in. If the image was already stored in the browser cache already, it will fade in immediately.
Using this for a product listing page.
This may not be the prettiest implementation but it does work well.
You can try to use CDATA to put all your symbols that don't work.
An example of something that will work in XML:
<![CDATA[
function matchwo(a,b) {
if (a < b && a < 0) {
return 1;
} else {
return 0;
}
}
]]>
And of course you can use < and >.
Check your server config file /etc/mysql/my.cnf - verify bind_address is not set to 127.0.0.1. Set it to 0.0.0.0 or comment it out then restart server with:
sudo service mysql restart
Example solution for adding the library to your PYTHONPATH.
Add the following line into your ~/.bashrc or just run it directly:
export PYTHONPATH="$PYTHONPATH:$HOME/.python"
Then link your required library into your ~/.python folder, e.g.
ln -s /home/user/work/project/foo ~/.python/
It is not about closing connection. EF manages connection correctly. My understanding of this problem is that there are multiple data retrieval commands executed on single connection (or single command with multiple selects) while next DataReader is executed before first one has completed the reading. The only way to avoid the exception is to allow multiple nested DataReaders = turn on MultipleActiveResultSets. Another scenario when this always happens is when you iterate through result of the query (IQueryable) and you will trigger lazy loading for loaded entity inside the iteration.
make sure ,use this 404 route wrote on the bottom of the code.
syntax will be like
{
path: 'page-not-found',

},
Thank you
You need to use preventDefault() to make it so the link does not go through when u click on it:
fiddle: http://jsfiddle.net/maniator/Sevdm/
$(function() {
$('.menulink').click(function(e){
e.preventDefault();
$("#bg").attr('src',"img/picture1.jpg");
});
});
Add the following css to your html and try changing the top, right, bottom, left values.
.modal {
position: absolute;
top: 10px;
right: 100px;
bottom: 0;
left: 0;
z-index: 10040;
overflow: auto;
overflow-y: auto;
}
diff -r will do this, telling you both if any files have been added or deleted, and what's changed in the files that have been modified.

If you are using oc4j to deploy the ear.
Make sure you set in the project the correct path for deploy.home=
You can fiind deploy.home in common.properties file
The oc4j needs to reload the new created class in the ear so that the server class and the client class have the same serialVersionUID
Try following code. It is working for me....

WHERE TableOne.id = TableTwo.id)
Try looking for EPOLLHUP or EPOLLERR. How do I check client connection is still alive
Reading and looking for 0 will work in some cases, but not all.

in hive 0.1 you can use SHOW CREATE TABLE to find the path where hive store data.
in other versions, there is no good way to do this.
upadted:
thanks Joe K
use DESCRIBE FORMATTED <table> to show table information.
ps: database.tablename is not supported here.
This is a nice way to do it:
Double d = 0.5;
float f = d.floatValue();
if you have d as a primitive type just add one line:
double d = 0.5;
Double D = Double.valueOf(d);
float f = D.floatValue();
This is work for me
@FOR /f "delims=" %i in ('reg query hklm\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion') DO set var=%i
echo %var%
Each tablespace has one or more datafiles that it uses to store data.
The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.
To find out if the actual limit is 32gb, run the following:
select value from v$parameter where name = 'db_block_size';
Compare the result you get with the first column below, and that will indicate what your max datafile size is.
I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).
Block Sz Max Datafile Sz (Gb) Max DB Sz (Tb)
-------- -------------------- --------------
2,048 8,192 524,264
4,096 16,384 1,048,528
8,192 32,768 2,097,056
16,384 65,536 4,194,112
32,768 131,072 8,388,224
You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):
select bytes/1024/1024 as mb_size,
maxbytes/1024/1024 as maxsize_set,
x.*
from dba_data_files x
MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).
If your datafile has a low max size or autoextend is not on you could simply run:
alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;
However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:
alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;
In my case, it's a typo caused this issue:
<VirtualHost *.8080>
should be
<VirtualHost *:8080>
Ran into the same problem and was able to tweak the resize mode until I found something I was happy with. Alternative approaches include:
To prevent loss of quality while tweaking images consider working with vector graphics so you can experiment with different sizes easily. Inkscape is free tool and works well for this purpose.
i think sometimes stop the redis-server and delete rdb,aof files? make sure there’s no data can be reloading. then start the redis-server,now it's new and empty.
componentDidMount() {
// Handle resize
window.addEventListener('resize', this.handleResize);
}
handleResize = () => {
this.renderer.setSize(this.mount.clientWidth, this.mount.clientHeight);
this.camera.aspect = this.mount.clientWidth / this.mount.clientHeight;
this.camera.updateProjectionMatrix();
};
Only need to define resize event function.
Then update the renderers size ( canvas ), assign a new aspect ratio for the camera.
Unmounting and remouting is a crazy solution in my opinion....
below is the mount if needed.
<div
className={this.state.canvasActive ? 'canvasContainer isActive' : 'canvasContainer'}
ref={mount => {
this.mount = mount;
}}
/>
401 means "Unauthorized", so there must be something with your credentials.
I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.
Authenticator.setDefault(new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(login, password.toCharArray());
}
});
and then simply invoking the regular url, without the credentials.
The other option is to provide the credentials in a Header:
String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);
PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.
I encountered a similar problem while using Sourcetree with newly created files (they wouldnt be included in the stash either).
When I first chose 'stage all' and then stash the newly added components where tracked and therefore included in the stash.
According to the Wordpress documentation, you should use wp_localize_script() in your functions.php file. This will create a Javascript Object in the header, which will be available to your scripts at runtime.
See Codex
Example:
<?php wp_localize_script('mylib', 'WPURLS', array( 'siteurl' => get_option('siteurl') )); ?>
To access this variable within in Javascript, you would simply do:
<script type="text/javascript">
var url = WPURLS.siteurl;
</script>

Oracle says (http://www.oracle.com/technology/products/database/utilities/htdocs/sql_loader_overview.html)
SQL*Loader is the primary method for quickly populating Oracle tables with data from external files
My experience is that their loader loads their tables faster than anything else.
JPA is a layered API, the different levels have their own annotations. The highest level is the (1) Entity level which describes persistent classes then you have the (2) relational database level which assume the entities are mapped to a relational database and (3) the java model.
Level 1 annotations: @Entity, @Id, @OneToOne, @OneToMany, @ManyToOne, @ManyToMany.
You can introduce persistency in your application using these high level annotations alone. But then you have to create your database according to the assumptions JPA makes. These annotations specify the entity/relationship model.
Level 2 annotations: @Table, @Column, @JoinColumn, ...
Influence the mapping from entities/properties to the relational database tables/columns if you are not satisfied with JPA's defaults or if you need to map to an existing database. These annotations can be seen as implementation annotations, they specify how the mapping should be done.
In my opinion it is best to stick as much as possible to the high level annotations and then introduce the lower level annotations as needed.
To answer the questions: the @OneToMany/mappedBy is nicest because it only uses the annotations from the entity domain. The @oneToMany/@JoinColumn is also fine but it uses an implementation annotation where this is not strictly necessary.
Thanks for this thread -- it helped me a lot too.
I learned something about .join() today.
These threads run in parallel:
d.start()
t.start()
d.join()
t.join()
and these run sequentially (not what I wanted):
d.start()
d.join()
t.start()
t.join()
In particular, I was trying to clever and tidy:
class Kiki(threading.Thread):
def __init__(self, time):
super(Kiki, self).__init__()
self.time = time
self.start()
self.join()
This works! But it runs sequentially. I can put the self.start() in __ init __, but not the self.join(). That has to be done after every thread has been started.
join() is what causes the main thread to wait for your thread to finish. Otherwise, your thread runs all by itself.
So one way to think of join() as a "hold" on the main thread -- it sort of de-threads your thread and executes sequentially in the main thread, before the main thread can continue. It assures that your thread is complete before the main thread moves forward. Note that this means it's ok if your thread is already finished before you call the join() -- the main thread is simply released immediately when join() is called.
In fact, it just now occurs to me that the main thread waits at d.join() until thread d finishes before it moves on to t.join().
In fact, to be very clear, consider this code:
import threading
import time
class Kiki(threading.Thread):
def __init__(self, time):
super(Kiki, self).__init__()
self.time = time
self.start()
def run(self):
print self.time, " seconds start!"
for i in range(0,self.time):
time.sleep(1)
print "1 sec of ", self.time
print self.time, " seconds finished!"
t1 = Kiki(3)
t2 = Kiki(2)
t3 = Kiki(1)
t1.join()
print "t1.join() finished"
t2.join()
print "t2.join() finished"
t3.join()
print "t3.join() finished"
It produces this output (note how the print statements are threaded into each other.)
$ python test_thread.py
32 seconds start! seconds start!1
seconds start!
1 sec of 1
1 sec of 1 seconds finished!
21 sec of
3
1 sec of 3
1 sec of 2
2 seconds finished!
1 sec of 3
3 seconds finished!
t1.join() finished
t2.join() finished
t3.join() finished
$
The t1.join() is holding up the main thread. All three threads complete before the t1.join() finishes and the main thread moves on to execute the print then t2.join() then print then t3.join() then print.
Corrections welcome. I'm also new to threading.
(Note: in case you're interested, I'm writing code for a DrinkBot, and I need threading to run the ingredient pumps concurrently rather than sequentially -- less time to wait for each drink.)
mysqli_select_db() should have 2 parameters, the connection link and the database name -
mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));
Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

You can add your attribute on callback function ({key} , speed.callback, like is
$('.usercontent').animate( {
backgroundColor:'#ddd',
},1000,function () {
$(this).css("backgroundColor","red")
});
You can use jquery Touch events. (see here)
let holdBtn = $('#holdBtn')
let holdDuration = 1000
let holdTimer
holdBtn.on('touchend', function () {
// finish hold
});
holdBtn.on('touchstart', function () {
// start hold
holdTimer = setTimeout(function() {
//action after certain time of hold
}, holdDuration );
});
The answers using subclasses or categories to allow VCs within UINavigationController and UITabBarController classes work well. Launching a portrait-only modal from a landscape tab bar controller failed. If you need to do this, then use the trick of displaying and hiding a non-animated modal view, but do it in the viewDidAppear method. It didn't work for me in viewDidLoad or viewWillAppear.
Apart from that, the solutions above work fine.
create java application in which you define two threads namely t1 and t2, thread t1 will generate random number 0 and 1 (simulate toss a coin ). 0 means head and one means tail. the other thread t2 will do the same t1 and t2 will repeat this loop 100 times and finally your application should determine how many times t1 guesses the number generated by t2 and then display the score. for example if thread t1 guesses 20 number out of 100 then the score of t1 is 20/100 =0.2 if t1 guesses 100 numbers then it gets score 1 and so on
I feel your pain. I've tried every answer above, including the setIncludeFontPadding to false, which did nothing for me.

This question is basically a duplicate of Is there a way to hide the new HTML5 spinbox controls shown in Google Chrome & Opera? but maybe not a full duplicate, since the motivation is given.
If the purpose is “browser's awareness of the content being purely numeric”, then you need to consider what that would really mean. The arrows, or spinners, are part of making numeric input more comfortable in some cases. Another part is checking that the content is a valid number, and on browsers that support HTML5 input enhancements, you might be able to do that using the pattern attribute. That attribute may also affect a third input feature, namely the type of virtual keyboard that may appear.
For example, if the input should be exactly five digits (like postal numbers might be, in some countries), then <input type="text" pattern="[0-9]{5}"> could be adequate. It is of course implementation-dependent how it will be handled.

If the type implements IDisposable, it automatically disposes that type.
Given:
public class SomeDisposableType : IDisposable
{
...implmentation details...
}
These are equivalent:
SomeDisposableType t = new SomeDisposableType();
try {
OperateOnType(t);
}
finally {
if (t != null) {
((IDisposable)t).Dispose();
}
}
using (SomeDisposableType u = new SomeDisposableType()) {
OperateOnType(u);
}
The second is easier to read and maintain.
I found 2 things worth mentioning while uploading files using webdav and http web request. First, for the provider I was using, I had to append the filename at the end of the provider url. Ihad to append the port number in the url. And I also set the Request method to PUT instead of POST.
example:
string webdavUrl = "https://localhost:443/downloads/test.pdf";
request.Method = "PUT";
You should use
import Dan.Vik;
This makes the class visible and the its public methods available.
exponent is a 1D array. This means that exponent[0] is a scalar, and exponent[0][i] is trying to access it as if it were an array.
Did you mean to say:
L = identity(len(l))
for i in xrange(len(l)):
L[i][i] = exponent[i]
or even
L = diag(exponent)
?
For OS X use this command:

The toolset on the client side would be one. And the familiarity with SOAP services the other. More and more services are going the RESTful route these days, and testing such services can be done with simple cURL examples. Although, it's not all that difficult to implement both methods and allow for the widest utilization from clients.
If you need to pick one, I'd suggest REST, it's easier.

Don't use spaces, use  .
People are saying "call exit(return code)," but this is bad form. In small programs it is fine, but there are a number of issues with this:
Really, the only time you should exit the problem is with this line in main.cpp:
return 0;
If you are using exit() to handle errors, you should learn about exceptions (and nesting exceptions), as a much more elegant and safe method.
string = ""
name = raw_input() #The value at the field
length = input() #the length of the field
string += name
string += " "*(length-len(name)) # Add extra spaces
This will add the number of spaces needed, provided the field has length >= the length of the name provided
If you use box-sizing: border-box means not only border, padding,margin, etc. All element will come inside of the parent element.
div p {_x000D_
box-sizing: border-box;_x000D_

}<div>_x000D_
<p>It was popularised in the 1960s with the release of Letraset sheets</p>_x000D_
</div>Judging by your above comment, you're OK doing this with jQuery — here goes:
// for every element in the body tag
$("*", "body").each(function() {
// parse out its computed font size, and see if it is less than 12
if ( parseInt($(this).css("font-size"), 10) < 12 )
// if so, then manually give it a CSS property of 12px
$(this).css("font-size", "12px")
});
A cleaner way to do this might be to have a "min-font" class in your CSS that sets font-size: 12px, and just add the class instead:
$("*", "body").each(function() {
if ( parseInt($(this).css("font-size"), 10) < 12 )
$(this).addClass("min-font")
});
Use RETURN QUERY:
CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
RETURNS TABLE (txt text -- also visible as OUT parameter inside function
, cnt bigint
, ratio bigint) AS
$func$
BEGIN
RETURN QUERY
SELECT t.txt
, count(*) AS cnt -- column alias only visible inside
, (count(*) * 100) / _max_tokens -- I added brackets
FROM (
SELECT t.txt
FROM token t
WHERE t.chartype = 'ALPHABETIC'
LIMIT _max_tokens
) t
GROUP BY t.txt
ORDER BY cnt DESC; -- potential ambiguity
END
$func$ LANGUAGE plpgsql;
Call:
SELECT * FROM word_frequency(123);
Explanation:
It is much more practical to explicitly define the return type than simply declaring it as record. This way you don't have to provide a column definition list with every function call. RETURNS TABLE is one way to do that. There are others. Data types of OUT parameters have to match exactly what is returned by the query.
Choose names for OUT parameters carefully. They are visible in the function body almost anywhere. Table-qualify columns of the same name to avoid conflicts or unexpected results. I did that for all columns in my example.
But note the potential naming conflict between the OUT parameter cnt and the column alias of the same name. In this particular case (RETURN QUERY SELECT ...) Postgres uses the column alias over the OUT parameter either way. This can be ambiguous in other contexts, though. There are various ways to avoid any confusion:
ORDER BY 2 DESC. Example:
ORDER BY count(*).plpgsql.variable_conflict or use the special command #variable_conflict error | use_variable | use_column in the function. See:
Don't use "text" or "count" as column names. Both are legal to use in Postgres, but "count" is a reserved word in standard SQL and a basic function name and "text" is a basic data type. Can lead to confusing errors. I use txt and cnt in my examples.
Added a missing ; and corrected a syntax error in the header. (_max_tokens int), not (int maxTokens) - type after name.
While working with integer division, it's better to multiply first and divide later, to minimize the rounding error. Even better: work with numeric (or a floating point type). See below.
This is what I think your query should actually look like (calculating a relative share per token):
CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
RETURNS TABLE (txt text
, abs_cnt bigint
, relative_share numeric) AS
$func$
BEGIN
RETURN QUERY
SELECT t.txt, t.cnt
, round((t.cnt * 100) / (sum(t.cnt) OVER ()), 2) -- AS relative_share
FROM (
SELECT t.txt, count(*) AS cnt
FROM token t
WHERE t.chartype = 'ALPHABETIC'
GROUP BY t.txt
ORDER BY cnt DESC
LIMIT _max_tokens
) t
ORDER BY t.cnt DESC;
END
$func$ LANGUAGE plpgsql;
The expression sum(t.cnt) OVER () is a window function. You could use a CTE instead of the subquery - pretty, but a subquery is typically cheaper in simple cases like this one.
A final explicit RETURN statement is not required (but allowed) when working with OUT parameters or RETURNS TABLE (which makes implicit use of OUT parameters).
round() with two parameters only works for numeric types. count() in the subquery produces a bigint result and a sum() over this bigint produces a numeric result, thus we deal with a numeric number automatically and everything just falls into place.

Here is your error, you are missing a ';' Change:
echo 'alert("review your answer")';
echo 'window.location= "index.php"';
To:
echo 'alert("review your answer");';
echo 'window.location= "index.php";';
Then a suggestion: You really should trigger that logic after some event. So, for instance:
document.getElementById("myBtn").onclick=function(){
alert("review your answer");
window.location= "index.php";
};
Another suggestion, use jQuery

you can use getopt to handle parameters in your bash script. there are not many explanations for getopt out there. here is an example:
#!/bin/sh
OPTIONS=$(getopt -o hf:gb -l help,file:,foo,bar -- "$@")
if [ $? -ne 0 ]; then
echo "getopt error"
exit 1
fi
eval set -- $OPTIONS
while true; do
case "$1" in
-h|--help) HELP=1 ;;
-f|--file) FILE="$2" ; shift ;;
-g|--foo) FOO=1 ;;
-b|--bar) BAR=1 ;;
--) shift ; break ;;
*) echo "unknown option: $1" ; exit 1 ;;
esac
shift
done
if [ $# -ne 0 ]; then
echo "unknown option(s): $@"
exit 1
fi
echo "help: $HELP"
echo "file: $FILE"
echo "foo: $FOO"
echo "bar: $BAR"

man getoptYou can easily do this though,
df.apply(LabelEncoder().fit_transform)
EDIT2:
In scikit-learn 0.20, the recommended way is
OneHotEncoder().fit_transform(df)
as the OneHotEncoder now supports string input. Applying OneHotEncoder only to certain columns is possible with the ColumnTransformer.
EDIT3:
Since this answer is over a year ago, and generated many upvotes (including a bounty), I should probably extend this further.
For inverse_transform and transform, you have to do a little bit of hack.
from collections import defaultdict
d = defaultdict(LabelEncoder)
With this, you now retain all columns LabelEncoder as dictionary.
# Encoding the variable
fit = df.apply(lambda x: d[x.name].fit_transform(x))
# Inverse the encoded
fit.apply(lambda x: d[x.name].inverse_transform(x))
# Using the dictionary to label future data
df.apply(lambda x: d[x.name].transform(x))
MOAR EDIT:
Using Neuraxle's FlattenForEach step, it's possible to do this as well to use the same LabelEncoder on all the flattened data at once:
FlattenForEach(LabelEncoder(), then_unflatten=True).fit_transform(df)
For using separate LabelEncoders depending for your columns of data, or if only some of your columns of data needs to be label-encoded and not others, then using a ColumnTransformer is a solution that allows for more control on your column selection and your LabelEncoder instances.
You'd have to rely on a non standard select2nd
You can use the Build Class to get the device information.
For example:

This is how I am checking if my app is in foreground. Note I am using AsyncTask as suggested by official Android documentation.`
`
private class CheckIfForeground extends AsyncTask<Void, Void, Void> {
@Override

ActivityManager activityManager = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
Log.i("Foreground App", appProcess.processName);
if (mContext.getPackageName().equalsIgnoreCase(appProcess.processName)) {
Log.i(Constants.TAG, "foreground true:" + appProcess.processName);
foreground = true;
// close_app();
}
}
}
Log.d(Constants.TAG, "foreground value:" + foreground);
if (foreground) {
foreground = false;
close_app();
Log.i(Constants.TAG, "Close App and start Activity:");
} else {
//if not foreground
close_app();
foreground = false;
Log.i(Constants.TAG, "Close App");
}
return null;
}
}
and execute AsyncTask like this.
new CheckIfForeground().execute();
Yes, it can be done as long as both windows are on the same domain. The window.open() function will return a handle to the new window. The child window can access the parent window using the DOM element "opener".
I discovered while following the above suggestions that for line in f: does not work for a pandas dataframe (not that anyone said it would) because the end of file in a dataframe is the last column, not the last row. for example if you have a data frame with 3 fields (columns) and 9 records (rows), the for loop will stop after the 3rd iteration, not after the 9th iteration. Teresa
read() is equivalent to recv() with a flags parameter of 0. Other values for the flags parameter change the behaviour of recv(). Similarly, write() is equivalent to send() with flags == 0.
File one:
angular.module('myApp.controllers', []);
File two:
angular.module('myApp.controllers').controller('Ctrl1', ['$scope', '$http', function($scope, $http){
}]);
File three:
angular.module('myApp.controllers').controller('Ctrl2', ['$scope', '$http', function($scope, $http){
}]);
Include in that order. I recommend 3 files so the module declaration is on its own.
As for folder structure there are many many many opinions on the subject, but these two are pretty good
Just append a div with that class to body, then remove it when you're done:
// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);
// Remove it (later)
$(".modal-backdrop").remove();

$("input").click(function() {_x000D_

The problem is that '_' underscores are not valid in header attribute. If removing the underscore is not an option you can add to the server block:
underscores_in_headers on;
This is basically a copy and paste from @kishorer747 comment on @Fleshgrinder answer, and solution is from: https://serverfault.com/questions/586970/nginx-is-not-forwarding-a-header-value-when-using-proxy-pass/586997#586997
I added it here as in my case the application behind nginx was working perfectly fine, but as soon ngix was between my flask app and the client, my flask app would not see the headers any longer. It was kind of time consuming to debug.
Maybe you could use:

The easier way is through the web management console:
Once you have an image you can launch another cloned instance, data and all. :)
I you have the char '9', it will store its ASCII code, so to get the int value, you have 2 ways
char x = '9';
int y = Character.getNumericValue(x); //use a existing function
System.out.println(y + " " + (y + 1)); // 9 10
or
char x = '9';
int y = x - '0'; // substract '0' code to get the difference
System.out.println(y + " " + (y + 1)); // 9 10
And it fact, this works also :
char x = 9;
System.out.println(">" + x + "<"); //> < prints a horizontal tab
int y = (int) x;
System.out.println(y + " " + (y + 1)); //9 10
You store the 9 code, which corresponds to a horizontal tab (you can see when print as String, bu you can also use it as int as you see above
You can use a similar construct by using the sys.columns table io sys.objects.

</div>Mockito cannot capture static methods, but since Mockito 2.14.0 you can simulate it by creating invocation instances of static methods.
Example (extracted from their tests):
public class StaticMockingExperimentTest extends TestBase {
Foo mock = Mockito.mock(Foo.class);
MockHandler handler = Mockito.mockingDetails(mock).getMockHandler();
Method staticMethod;
InvocationFactory.RealMethodBehavior realMethod = new InvocationFactory.RealMethodBehavior() {
@Override
public Object call() throws Throwable {
return null;
}
};
@Before
public void before() throws Throwable {
staticMethod = Foo.class.getDeclaredMethod("staticMethod", String.class);
}
@Test
public void verify_static_method() throws Throwable {
//register staticMethod call on mock
Invocation invocation = Mockito.framework().getInvocationFactory().createInvocation(mock, withSettings().build(Foo.class), staticMethod, realMethod,
"some arg");
handler.handle(invocation);
//verify staticMethod on mock
//Mockito cannot capture static methods so we will simulate this scenario in 3 steps:
//1. Call standard 'verify' method. Internally, it will add verificationMode to the thread local state.
// Effectively, we indicate to Mockito that right now we are about to verify a method call on this mock.
verify(mock);
//2. Create the invocation instance using the new public API
// Mockito cannot capture static methods but we can create an invocation instance of that static invocation
Invocation verification = Mockito.framework().getInvocationFactory().createInvocation(mock, withSettings().build(Foo.class), staticMethod, realMethod,
"some arg");
//3. Make Mockito handle the static method invocation
// Mockito will find verification mode in thread local state and will try verify the invocation
handler.handle(verification);
//verify zero times, method with different argument
verify(mock, times(0));
Invocation differentArg = Mockito.framework().getInvocationFactory().createInvocation(mock, withSettings().build(Foo.class), staticMethod, realMethod,
"different arg");
handler.handle(differentArg);
}
@Test
public void stubbing_static_method() throws Throwable {
//register staticMethod call on mock
Invocation invocation = Mockito.framework().getInvocationFactory().createInvocation(mock, withSettings().build(Foo.class), staticMethod, realMethod,
"foo");
handler.handle(invocation);
//register stubbing
when(null).thenReturn("hey");
//validate stubbed return value
assertEquals("hey", handler.handle(invocation));
assertEquals("hey", handler.handle(invocation));
//default null value is returned if invoked with different argument
Invocation differentArg = Mockito.framework().getInvocationFactory().createInvocation(mock, withSettings().build(Foo.class), staticMethod, realMethod,
"different arg");
assertEquals(null, handler.handle(differentArg));
}
static class Foo {
private final String arg;
public Foo(String arg) {
this.arg = arg;
}
public static String staticMethod(String arg) {
return "";
}
@Override
public String toString() {
return "foo:" + arg;
}
}
}
Their goal is not to directly support static mocking, but to improve its public APIs so that other libraries, like Powermockito, don't have to rely on internal APIs or directly have to duplicate some Mockito code. (source)
Disclaimer: Mockito team thinks that the road to hell is paved with static methods. However, Mockito's job is not to protect your code from static methods. If you don’t like your team doing static mocking, stop using Powermockito in your organization. Mockito needs to evolve as a toolkit with an opinionated vision on how Java tests should be written (e.g. don't mock statics!!!). However, Mockito is not dogmatic. We don't want to block unrecommended use cases like static mocking. It's just not our job.
By omitting all parts of the head, the loop can also become infinite:
for (;;) {}
I had tried many different solutions. This was the only one that worked for me in that it was able to pick up on styles applied at class level and at style as directly attributed on the element. So a font set at css file level and one as a style attribute; it returned the correct font.
It is simple! (Sorry, can't find where I originally found it)
//-- html object
var element = htmlObject; //e.g document.getElementById
//-- or jquery object
var element = htmlObject[0]; //e.g $(selector)
var stylearray = document.defaultView.getComputedStyle(element, null);
var font = stylearray["font-family"]
Alternatively you can list all the style by cycling through the array
for (var key in stylearray) {
console.log(key + ': ' + stylearray[key];
}
See the example on the filter page. Use an object, and set the color in the color property:
Search by color: <input type="text" ng-model="search.color">
<div ng-repeat="product in products | filter:search">

What to do:
When I modify a page (web), I update and when I refresh web browser: is all there with my mod. I did configured Jboss for autoscanning (not sure it did helped)
All of these are good answers, but I would like to suggest one more that I feel is a better code standard. You may choose to use a flag in the loop condition that indicates whether or not to continue looping and avoid using break all together.
$arr = array('one', 'two', 'three', 'four', 'stop', 'five');
$length = count($arr);
$found = false;
for ($i = 0; $i < $length && !$found; $i++) {
$val = $arr[$i];
if ($val == 'stop') {
$found = true; // this will cause the code to
// stop looping the next time
// the condition is checked
}
echo "$val<br />\n";
}
I consider this to be better code practice because it does not rely on the scope that break is used. Rather, you define a variable that indicates whether or not to break a specific loop. This is useful when you have many loops that may or may not be nested or sequential.
After doing a git fetch, you can run git status to show how many commits the local branch is ahead or behind of the remote version of the branch.
This won't show you how many commits it is ahead or behind of a different branch though. Your options are the full diff, looking at github, or using a solution like Vimhsa linked above: Git status over all repo's
Under your main views.py add your own custom implementation of the following two views, and just set up the templates 404.html and 500.html with what you want to display.
With this solution, no custom code needs to be added to urls.py
Here's the code:
from django.shortcuts import render_to_response
from django.template import RequestContext
def handler404(request, *args, **argv):
response = render_to_response('404.html', {},
context_instance=RequestContext(request))
response.status_code = 404
return response
def handler500(request, *args, **argv):
response = render_to_response('500.html', {},
context_instance=RequestContext(request))
response.status_code = 500
return response
Update
handler404 and handler500 are exported Django string configuration variables found in django/conf/urls/__init__.py. That is why the above config works.
To get the above config to work, you should define the following variables in your urls.py file and point the exported Django variables to the string Python path of where these Django functional views are defined, like so:
# project/urls.py
handler404 = 'my_app.views.handler404'
handler500 = 'my_app.views.handler500'
Update for Django 2.0
Signatures for handler views were changed in Django 2.0: https://docs.djangoproject.com/en/2.0/ref/views/#error-views
If you use views as above, handler404 will fail with message:
"handler404() got an unexpected keyword argument 'exception'"
In such case modify your views like this:
def handler404(request, exception, template_name="404.html"):
response = render_to_response(template_name)
response.status_code = 404
return response
For those who are interested in using extensions vs pragma marks (as mentioned in the first comment), here is how to implement it from a Swift Engineer:
import UIKit
class SwiftTableViewController: UITableViewController {
init(coder aDecoder: NSCoder!) {
super.init(coder: aDecoder)
}
override func viewDidLoad() {
super.viewDidLoad()
}
}
extension SwiftTableViewController {
override func numberOfSectionsInTableView(tableView: UITableView?) -> Int {
return 1
}
override func tableView(tableView: UITableView?, numberOfRowsInSection section: Int) -> Int {
return 5
}
override func tableView(tableView: UITableView?, cellForRowAtIndexPath indexPath: NSIndexPath?) -> UITableViewCell? {
let cell = tableView?.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath) as UITableViewCell;
cell.textLabel.text = "Hello World"
return cell
}
}
It's also not necessarily the best practice, but this is how you do it if you like.
The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.
Do what the error message says:
Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections
You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:
PostgreSQL isn't running
PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)
PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.
PostgreSQL is listening on a different port to the one you're connecting on
(unlikely) there's an iptables rule blocking loopback connections
(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).
So ... check those:
ps -f -u postgres should list postgres processes
sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on
BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:
$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 12345?

Now there are a lot of cloud providers , providing solutions like MBaaS (Mobile Backend as a Service). Some only give access to cloud database, some will do the user management for you, some let you place code around cloud database and there are facilities of access control, push notifications, analytics, integrated image and file hosting etc.
Here are some providers which have a "free-tier" (may change in future):

I'd like to share my example related to security in addition to Daniel Fernández.
<div th:switch="${#authentication}? ${#authorization.expression('isAuthenticated()')} : ${false}">
<span th:case="${false}">User is not logged in</span>
<span th:case="${true}">Logged in user</span>
<span th:case="*">Should never happen, but who knows...</span>
</div>
Here is complex expression with mixed 'authentication' and 'authorization' utility objects which produces 'true/false' result for thymeleaf template code.
The 'authentication' and 'authorization' utility objects came from thymeleaf extras springsecurity3 library. When 'authentication' object is not available OR authorization.expression('isAuthenticated()') evaluates to 'false', expression returns ${false}, otherwise ${true}.
As a concept, the head is the latest revision in a branch. If you have more than one head per named branch you probably created it when doing local commits without merging, effectively creating an unnamed branch.
To have a "clean" repository, you should have one head per named branch and always merge to a named branch after you worked locally.
This is also true for Mercurial.
code for radio button -

var gender=$('#Gender').val();
if ($("#Gender:checked").length == 0){
$('.GenderValidation').text("Gender is required.");
return false;

^\+[1-9]{1}[0-9]{7,11}$
The Regular Expression ^\+[1-9]{1}[0-9]{7,11}$ fails for "+290 8000" and similar valid numbers that are shorter than 8 digits.
The longest numbers could be something like 3 digit country code, 3 digit area code, 8 digit subscriber number, making 14 digits.
My suspicion is that it has to do with how server-side controls are identified during processing. Rather than having to check every control at runtime by name to determine whether server-side processing needs to be done, it does a selection on the internal node representation by tag. The compiler checks to make sure that all controls that require server tags have them during the validation step.
You have to be careful, server responses in the range of 4xx and 5xx throw a WebException. You need to catch it, and then get status code from a WebException object:
try
{
wResp = (HttpWebResponse)wReq.GetResponse();
wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}
Open cmd type adb shell then press enter.
Type ls to view files list.
If that's a valid date/time entry then excel simply stores it as a number (days are integers and the time is the decimal part) so you can do a simple subtraction.
I'm not sure if 7/6 is 7th June or 6th July, assuming the latter then it's a future date so you can get the difference in days with
=INT(A1-TODAY())
Make sure you format result cell as general or number (not date)

Is the correct format for matching a generic international phone number. I replaced the US land line centric international access code 011 with the standard international access code identifier of '+', making it mandatory. I also changed the minimum for the national number to at least one digit.
Note that if you enter numbers in this format into your mobile phone address book, you may successfully call any number in your address book no matter where you travel. For land lines, replace the plus with the international access code for the country you are dialing from.
Note that this DOES NOT take into account national number plan rules - specifically, it allows zeros and ones in locations that national number plans may not allow and also allows number lengths greater than the national number plan for some countries (e.g., the US).

· NUM1 -eq NUM2 returns true if NUM1 and NUM2 are numerically equal.
· NUM1 -ne NUM2 returns true if NUM1 and NUM2 are not numerically equal.
· NUM1 -gt NUM2 returns true if NUM1 is greater than NUM2.
· NUM1 -ge NUM2 returns true if NUM1 is greater than or equal to NUM2.
· NUM1 -lt NUM2 returns true if NUM1 is less than NUM2.
· NUM1 -le NUM2 returns true if NUM1 is less than or equal to NUM2.
For example
if [[ $age > 21 ]] # bad, > is a string comparison operator
if [ $age > 21 ] # bad, > is a redirection operator
if [[ $age -gt 21 ]] # okay, but fails if $age is not numeric
if (( $age > 21 )) # best, $ on age is optional
There are three different approaches to consider, as described in the reference
At the risk of irritating you;
You're asking the wrong question. You don't need a reason NOT to deviate from the defaults, but the other way around. You need a reason to do so. Timeouts are absolutely essential when running a web server and to disable that setting without a reason is inherently contrary to good practice, even if it's running on a web server that happens to have a timeout directive of its own.
Now, as for the real answer; probably it doesn't matter at all in this particular case, but it's bad practice to go by the setting of a separate system. What if the script is later run on a different server with a different timeout? If you can safely say that it will never happen, fine, but good practice is largely about accounting for seemingly unlikely events and not unnecessarily tying together the settings and functionality of completely different systems. The dismissal of such principles is responsible for a lot of pointless incompatibilities in the software world. Almost every time, they are unforeseen.
What if the web server later is set to run some other runtime environment which only inherits the timeout setting from the web server? Let's say for instance that you later need a 15-year-old CGI program written in C++ by someone who moved to a different continent, that has no idea of any timeout except the web server's. That might result in the timeout needing to be changed and because PHP is pointlessly relying on the web server's timeout instead of its own, that may cause problems for the PHP script. Or the other way around, that you need a lesser web server timeout for some reason, but PHP still needs to have it higher.
It's just not a good idea to tie the PHP functionality to the web server because the web server and PHP are responsible for different roles and should be kept as functionally separate as possible. When the PHP side needs more processing time, it should be a setting in PHP simply because it's relevant to PHP, not necessarily everything else on the web server.
In short, it's just unnecessarily conflating the matter when there is no need to.
Last but not least, 'stillstanding' is right; you should at least rather use set_time_limit() than ini_set().
Hope this wasn't too patronizing and irritating. Like I said, probably it's fine under your specific circumstances, but it's good practice to not assume your circumstances to be the One True Circumstance. That's all. :)
Another variation:
git branch -r --sort=-committerdate --format='%(HEAD)%(color:yellow)%(refname:short)|%(color:bold green)%(committerdate:relative)|%(color:blue)%(subject)|%(color:magenta)%(authorname)%(color:reset)' --color=always | column -ts'|'
Worth noting that even though it's looking at changes in remote branches, it's worth syncing with origin before running the command (can use git fetch), as I found it can return out of date information if your local Git folder hasn't been updated in a while.
Also, this is a version that works in Windows cmd and PowerShell (didn't get output displayed in columns, would be interested to see if anyone gets this working):
git branch -r --sort=-committerdate --format="%(HEAD)%(color:yellow)%(refname:short)|%(color:bold green)%(committerdate:relative)|%(color:blue)%(subject)|%(color:magenta)%(authorname)%(color:reset)" --color=always
You should look into normalizing your database to avoid creating columns at runtime.
Make 3 tables:
Put questions and assessments in their respective tables and link them together through assessment_question using foreign keys.
You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp is not a good ideabyte[]: example hereshowHelp() to avoid overwriting the file if two users send a request at the same timeMicrosoft has a tool called JLCA: Java Language Conversion Assistant. I can't tell if it is better though, as I have never compared the two.
Had the same problem. I my case the build.gradel(app) was missing buildToolsVersion "27.0.0". So I open a previously working project to determine the version and added this line buildToolsVersion "27.0.0". Now it works fine.
Hope this helps.
I do it as below
$("a[rel=popover]").click(function(event){
if(event.which == 1)
{
$thisPopOver = $(this);
$thisPopOver.popover('toggle');
$thisPopOver.parent("li").click(function(event){
event.stopPropagation();
$("html").click(function(){
$thisPopOver.popover('hide');
});
});
}
});
Hope this helps!
I thought I would add to this question as it is the top google search result.
As has been noted in the comments, in EF Core there is no support for using annotations (Key attribute) and it must be done with fluent.
As I was working on a large migration from EF6 to EF Core this was unsavoury and so I tried to hack it by using Reflection to look for the Key attribute and then apply it during OnModelCreating
// get all composite keys (entity decorated by more than 1 [Key] attribute
foreach (var entity in modelBuilder.Model.GetEntityTypes()
.Where(t =>
t.ClrType.GetProperties()
.Count(p => p.CustomAttributes.Any(a => a.AttributeType == typeof(KeyAttribute))) > 1))
{
// get the keys in the appropriate order
var orderedKeys = entity.ClrType
.GetProperties()
.Where(p => p.CustomAttributes.Any(a => a.AttributeType == typeof(KeyAttribute)))
.OrderBy(p =>
p.CustomAttributes.Single(x => x.AttributeType == typeof(ColumnAttribute))?
.NamedArguments?.Single(y => y.MemberName == nameof(ColumnAttribute.Order))
.TypedValue.Value ?? 0)
.Select(x => x.Name)
.ToArray();
// apply the keys to the model builder
modelBuilder.Entity(entity.ClrType).HasKey(orderedKeys);
}
I haven't fully tested this in all situations, but it works in my basic tests. Hope this helps someone
All radio buttons inside of a share container are in the same group by default.
Means, if you check one of them - others will be unchecked.
If you want to create independent groups of radio buttons, you must situate them into different containers such as Group Box, or control their Checked state through code behind.
Add white-space: nowrap;:

If you have setup correctly the AndroidManifest.xml file with activity parent, you can use :
NavUtils.navigateUpFromSameTask(this);
Where this is your child activity.
$_='~s/blue/red/g';
Uh, what??
Just
s/blue/red/g;
or, if you insist on using a variable (which is not necessary when using $_, but I just want to show the right syntax):
$_ =~ s/blue/red/g;

Yes, I found MySQL also cannot edit result tables. Usually results tables joining other tables don't have primary keys. I heard other suggested put the result table in another table, but the better solution is to use Dbeaver which can edit result tables.
The problem is that undefined compared to null using == gives true. The common check for undefined is therefore done like this:
typeof x == "undefined"
this ensures the type of the variable is really undefined.
I was using above command but it was not working. This command worked for me:

Best way is to add tr between two tr like below,
<tr>
<td height="5" colspan="2"></td>
</tr>this works in OS 10.8 in the .bash_profile

The easiest and quickest I find is this
ALTER TABLE mydb.mytable
ADD COLUMN mycolumnname INT NOT NULL AUTO_INCREMENT AFTER updated,
ADD UNIQUE INDEX mycolumnname_UNIQUE (mycolumname ASC);
You need to escape the % with another...

For me, when I was running "flutter doctor" command from Ubuntu Command line - It showed me below error.
[?] Android toolchain - develop for Android devices ? Unable to locate Android SDK.
From this error, it is obvious that "flutter doctor" was not able to find the "android sdk" and the reason for that was my android sdk was downloaded in a custom location on my Ubuntu machine.
So we must need to tell "flutter doctor" about this custom android location, using below command,
flutter config --android-sdk /home/myhome/Downloads/softwares/android-sdk/
Need to replace /home/myhome/Downloads/softwares/android-sdk/ with path to your custom location/place where android sdk is available.
Once this is done, and re-run "flutter doctor" and now it has detected the android sdk location and hence I could run avd/emulator by typing "flutter run"
This code removes repetition of characters i.e, if the input is aaabbcc then the output will be abc. (the array must be sorted for this code to work)
cin >> s;
ans = "";
ans += s[0];
for(int i = 1;i < s.length();++i)
if(s[i] != s[i-1])
ans += s[i];
cout << ans << endl;
I find it very convenient to build a regular expression pattern by stringing together multiple smaller patterns.
import re
string = "begin:id1:tag:middl:id2:tag:id3:end"
re_str1 = r'(?<=(\S{5})):'
re_str2 = r'(id\d+):(?=tag:)'
re_pattern = re.compile(re_str1 + re_str2)
match = re_pattern.findall(string)
print(match)
Output:
[('begin', 'id1'), ('middl', 'id2')]
perhaps not the most elegant way to solve this

Have a look at the try-with-resources statement. For example:
try (BufferedReader br = new BufferedReader(new FileReader(path))) {
System.out.println(br.readLine());
} catch (Exception e) {
...
} finally {
...
}
Here the resource that is no longer needed is freed in the BufferedReader.close() method. You can create your own class that implements AutoCloseable and use it in a similar fashion.
This statement is more limited than finalize in terms of code structuring, but at the same time it makes the code simpler to understand and maintain. Also, there is no guarantee that a finalize method is called at all during the livetime of the application.
The sed command allows you to use other characters instead of / as separator:
sed 's#"http://www\.fubar\.com"#URL_FUBAR#g'
The double quotes are not a problem.
This string.split("~")[0]; gets things done.
source: String.prototype.split()
Another functional approach using curry and function composition.
So the first thing would be the split function. We want to make this "john smith~123 Street~Apt 4~New York~NY~12345" into this ["john smith", "123 Street", "Apt 4", "New York", "NY", "12345"]
const split = (separator) => (text) => text.split(separator);
const splitByTilde = split('~');
So now we can use our specialized splitByTilde function. Example:
splitByTilde("john smith~123 Street~Apt 4~New York~NY~12345") // ["john smith", "123 Street", "Apt 4", "New York", "NY", "12345"]
To get the first element we can use the list[0] operator. Let's build a first function:
const first = (list) => list[0];
The algorithm is: split by the colon and then get the first element of the given list. So we can compose those functions to build our final getName function. Building a compose function with reduce:
const compose = (...fns) => (value) => fns.reduceRight((acc, fn) => fn(acc), value);
And now using it to compose splitByTilde and first functions.
const getName = compose(first, splitByTilde);
let string = 'john smith~123 Street~Apt 4~New York~NY~12345';
getName(string); // "john smith"
Update:
As noted by @iX3, Typescript 2.4 has support for enum strings.
See:Create an enum with string values in Typescript
Original answer:
For String member values, TypeScript only allows numbers as enum member values. But there are a few solutions/hacks you can implement;
Solution 1:
copied from: https://blog.rsuter.com/how-to-implement-an-enum-with-string-values-in-typescript/
There is a simple solution: Just cast the string literal to any before assigning:
export enum Language {
English = <any>"English",
German = <any>"German",
French = <any>"French",
Italian = <any>"Italian"
}
solution 2:
copied from: https://basarat.gitbooks.io/typescript/content/docs/types/literal-types.html
You can use a string literal as a type. For example:
let foo: 'Hello';
Here we have created a variable called foo that will only allow the literal value 'Hello' to be assigned to it. This is demonstrated below:
let foo: 'Hello';
foo = 'Bar'; // Error: "Bar" is not assignable to type "Hello"
They are not very useful on their own but can be combined in a type union to create a powerful (and useful) abstraction e.g.:
type CardinalDirection =
"North"
| "East"
| "South"
| "West";
function move(distance: number, direction: CardinalDirection) {
// ...
}
move(1,"North"); // Okay
move(1,"Nurth"); // Error!
By the answer of rudivonstaden
txtBlock.Text = await response.Content.ReadAsStringAsync();
but if you don't want to make the method async you can use
txtBlock.Text = response.Content.ReadAsStringAsync();
txtBlock.Text.Wait();
Wait() it's important, bec?use we are doing async operations and we must wait for the task to complete before going ahead.
Well, you're on the right path, Benno!
There are some tips regarding VBA programming that might help you out.
Use always explicit references to the sheet you want to interact with. Otherwise, Excel may 'assume' your code applies to the active sheet and eventually you'll see it screws your spreadsheet up.
As lionz mentioned, get in touch with the native methods Excel offers. You might use them on most of your tricks.
Explicitly declare your variables... they'll show the list of methods each object offers in VBA. It might save your time digging on the internet.
Now, let's have a draft code...
Remember this code must be within the Excel Sheet object, as explained by lionz. It only applies to Sheet 2, is up to you to adapt it to both Sheet 2 and Sheet 3 in the way you prefer.
Hope it helps!
Private Sub Worksheet_Change(ByVal Target As Range)
Dim oSheet As Excel.Worksheet
'We only want to do something if the changed cell is B6, right?
If Target.Address = "$B$6" Then
'Checks if it's a number...
If IsNumeric(Target.Value) Then
'Let's avoid values out of your bonds, correct?
If Target.Value > 0 And Target.Value < 51 Then
'Let's assign the worksheet we'll show / hide rows to one variable and then
' use only the reference to the variable itself instead of the sheet name.
' It's safer.
'You can alternatively replace 'sheet 2' by 2 (without quotes) which will represent
' the sheet index within the workbook
Set oSheet = ActiveWorkbook.Sheets("Sheet 2")
'We'll unhide before hide, to ensure we hide the correct ones
oSheet.Range("A7:A56").EntireRow.Hidden = False
oSheet.Range("A" & Target.Value + 7 & ":A56").EntireRow.Hidden = True
End If
End If
End If
End Sub
You can simply do something like...
...
<head>
...
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'your-app-id', // you need to create an facebook app
autoLogAppEvents : true,
xfbml : true,
version : 'v3.3'
});
};
</script>
<script async defer src="https://connect.facebook.net/en_US/sdk.js"></script>
</head>
<body>
...
<button id="share-btn"></button>
<!-- load jquery -->
<script>
$('#share-btn').on('click', function () {
FB.ui({
method: 'share',
href: location.href, // Current url
}, function (response) { });
});
</script>
</body>
I always use the clock_gettime() function, returning time from the CLOCK_MONOTONIC clock. The time returned is the amount of time, in seconds and nanoseconds, since some unspecified point in the past, such as system startup of the epoch.
#include <stdio.h>
#include <stdint.h>
#include <time.h>
int64_t timespecDiff(struct timespec *timeA_p, struct timespec *timeB_p)
{
return ((timeA_p->tv_sec * 1000000000) + timeA_p->tv_nsec) -
((timeB_p->tv_sec * 1000000000) + timeB_p->tv_nsec);
}
int main(int argc, char **argv)
{
struct timespec start, end;
clock_gettime(CLOCK_MONOTONIC, &start);
// Some code I am interested in measuring
clock_gettime(CLOCK_MONOTONIC, &end);
uint64_t timeElapsed = timespecDiff(&end, &start);
}
You can use this code it works fine.
var pinImage = new google.maps.MarkerImage("http://www.googlemapsmarkers.com/v1/009900/");

});
In addition to Rob's answer. That class must inherit from NSObject, and we have 3 ways to trigger property change
Use setValue(value: AnyObject?, forKey key: String) from NSKeyValueCoding
class MyObjectToObserve: NSObject {
var myDate = NSDate()
func updateDate() {
setValue(NSDate(), forKey: "myDate")
}
}
Use willChangeValueForKey and didChangeValueForKey from NSKeyValueObserving
class MyObjectToObserve: NSObject {
var myDate = NSDate()
func updateDate() {
willChangeValueForKey("myDate")
myDate = NSDate()
didChangeValueForKey("myDate")
}
}
Use dynamic. See Swift Type Compatibility
You can also use the dynamic modifier to require that access to members be dynamically dispatched through the Objective-C runtime if you’re using APIs like key–value observing that dynamically replace the implementation of a method.
class MyObjectToObserve: NSObject {
dynamic var myDate = NSDate()
func updateDate() {
myDate = NSDate()
}
}
And property getter and setter is called when used. You can verify when working with KVO. This is an example of computed property
class MyObjectToObserve: NSObject {
var backing: NSDate = NSDate()
dynamic var myDate: NSDate {
set {
print("setter is called")
backing = newValue
}
get {
print("getter is called")
return backing
}
}
}
