Install instructions on the Composer Docs page are quite to the point otherwise.
>>> thetuple = (1, 2, 3)
>>> print "this is a tuple: %s" % (thetuple,)
this is a tuple: (1, 2, 3)
Making a singleton tuple with the tuple of interest as the only item, i.e. the (thetuple,)
part, is the key bit here.
I couldn't just use the <xsl:text>
</xsl:text>
approach because if I format the XML file using XSLT the entity will disappear. So I had to use a slightly more round about approach using variables
<xsl:variable name="nl" select="' '"/>
<xsl:template match="/">
<xsl:value-of select="$nl" disable-output-escaping="no"/>
<xsl:apply-templates select="*"/>
</xsl:template>
This is what I use to sort in memory - it can easily be expanded to sort an array.

You could use normal buttons(non submit). Use javascript to rewrite (at an 'onclick' event) the form's 'action' attribute to something you want and then submit it. Generate the button using a custom helper(create a file "Helper.cshtml" inside the App_Code folder, at the root of your project) .
@helper SubmitButton(string text, string controller,string action)
{
var uh = new System.Web.Mvc.UrlHelper(Context.Request.RequestContext);
string url = @uh.Action(action, controller, null);
<input type=button onclick="(
function(e)
{
$(e).parent().attr('action', '@url'); //rewrite action url
//create a submit button to be clicked and removed, so that onsubmit is triggered
var form = document.getElementById($(e).parent().attr('id'));
var button = form.ownerDocument.createElement('input');
button.style.display = 'none';
button.type = 'submit';
form.appendChild(button).click();
form.removeChild(button);
}
)(this)" value="@text"/>
}
And then use it as:
@Helpers.SubmitButton("Text for 1st button","ControllerForButton1","ActionForButton1")
@Helpers.SubmitButton("Text for 2nd button","ControllerForButton2","ActionForButton2")
...
Inside your form.

VirtualBox is a virtualizer, not an emulator. (The name kinda gives it away.) I.e. it can only virtualize a CPU that is actually there, not emulate one that isn't. In particular, VirtualBox can only virtualize x86 and AMD64 CPUs. iOS only runs on ARM CPUs.
Using NLTK:
from nltk.corpus import wordnet
if not wordnet.synsets(word_to_test):
#Not an English Word
else:
#English Word
You should refer to this article if you have trouble installing wordnet or want to try other approaches.
Use the first example. If the key doesn't exist it will be added.
var a = new Array();
a['name'] = 'oscar';
alert(a['name']);
Will pop up a message box containing 'oscar'.
Try:
var text = 'name = oscar'
var dict = new Array()
var keyValuePair = text.replace(/ /g,'').split('=');
dict[ keyValuePair[0] ] = keyValuePair[1];
alert( dict[keyValuePair[0]] );
the best way to do it is
const object = Object.keys(o).sort().reduce((r, k) => (r[k] = o[k], r), {})
//else if its in reverse just do
const object = Object.keys(0).reverse ()
You can first convert your almost-array-like object to a real array, and then use .reverse():
Object.assign([], {1:'banana', 2:'apple',
3:'orange'}).reverse();
// [ "orange", "apple", "banana", <1 empty slot> ]
The empty slot at the end if cause because your first index is 1 instead of 0. You can remove the empty slot with .length-- or .pop().
Alternatively, if you want to borrow .reverse and call it on the same object, it must be a fully-array-like object. That is, it needs a length property:
Array.prototype.reverse.call({1:'banana', 2:'apple',
3:'orange', length:4});
// {0:"orange", 1:"apple", 3:"banana", length:4}
Note it will return the same fully-array-like object object, so it won't be a real array. You can then use delete to remove the length property.
mock.patch
is a very very different critter than mock.Mock
. patch
replaces the class with a mock object and lets you work with the mock instance. Take a look at this snippet:
>>> class MyClass(object):
... def __init__(self):
... print 'Created MyClass@{0}'.format(id(self))
...
>>> def create_instance():
... return MyClass()
...
>>> x = create_instance()
Created MyClass@4299548304
>>>
>>> @mock.patch('__main__.MyClass')
... def create_instance2(MyClass):
... MyClass.return_value = 'foo'
... return create_instance()
...
>>> i = create_instance2()
>>> i
'foo'
>>> def create_instance():
... print MyClass
... return MyClass()
...
>>> create_instance2()
<mock.Mock object at 0x100505d90>
'foo'
>>> create_instance()
<class '__main__.MyClass'>
Created MyClass@4300234128
<__main__.MyClass object at 0x100505d90>
patch
replaces MyClass
in a way that allows you to control the usage of the class in functions that you call. Once you patch a class, references to the class are completely replaced by the mock instance.
mock.patch
is usually used when you are testing something that creates a new instance of a class inside of the test. mock.Mock
instances are clearer and are preferred. If your self.sut.something
method created an instance of MyClass
instead of receiving an instance as a parameter, then mock.patch
would be appropriate here.
SELECT

< table_name >
WHERE

That's 32 hex characters - 1 hex character is 4 bits.
I had the same problem. I solve it with a for loop.
Example:
If I want to write in 2 identical tables, using a loop
for x = 0 to 1
if x = 0 then TableToWrite = "Table1"
if x = 1 then TableToWrite = "Table2"
Sql = "INSERT INTO " & TableToWrite & " VALUES ('1','2','3')"
NEXT
either
ArrTable = ("Table1", "Table2")
for xArrTable = 0 to Ubound(ArrTable)
Sql = "INSERT INTO " & ArrTable(xArrTable) & " VALUES ('1','2','3')"
NEXT
If you have a small query I don't know if this is the best solution, but if you your query is very big and it is inside a dynamical script with if/else/case conditions this is a good solution.

I like the regex that was published in "Javascript: The Good Parts". Its not too short and not too complex. This page on github also has the JavaScript code that uses it. But it an be adapted for any language. https://gist.github.com/voodooGQ/4057330
XmlDocument doc = new XmlDocument();
doc.LoadXml(str);
Where str
is your XML string. See the MSDN article for more info.
In my case, I still wanted the open on odd pages option but this would produce a blank page with the chapter name in the header. I didn't want the header. And so to avoid this I used this at the end of the chapter:
\clearpage
\thispagestyle{plain}
This let's you keep the blank page on the last even page of the chapter but without the header.
Maybe I'm missing something but you want to wind up with a String that looks like this, "999897969594...543210"
, correct?
StringBuilder sb = new StringBuilder();
for(int i=99;i>=0;i--){
sb.append(String.valueOf(i));
}
This a single solution, in where your_field is a field that will set and new_value is a new value field, that can a function or a single value
foreach ($array as $key => $item) {
$item["your_field"] = "new_value";
$array[$key] = $item;
}
In your case new_value will be a date() function
since answers are disappointing I would like suggest a way in which I got deleted stuff back.
I use an ide to code and accidently I used rm -rf from terminal to remove complete folder. Thanks to ide I recoved it back by reverting the change from ide's local history.
(my ide is intelliJ but all ide's support history backup)
If you want to follow all the "best practices," there's a few things I'd recommend, some of which are touched on in other answers and comments to this question.
First, while it doesn't have too much of an affect on the specific question you asked, you did mention efficiency, and the best way to handle shared data in your application is to factor it out into a service.
I would personally recommend embracing AngularJS's promise system, which will make your asynchronous services more composable compared to raw callbacks. Luckily, Angular's $http
service already uses them under the hood. Here's a service that will return a promise that resolves to the data from the JSON file; calling the service more than once will not cause a second HTTP request.
app.factory('locations', function($http) {
var promise = null;
return function() {
if (promise) {
// If we've already asked for this data once,
// return the promise that already exists.
return promise;
} else {
promise = $http.get('locations/locations.json');
return promise;
}
};
});
As far as getting the data into your directive, it's important to remember that directives are designed to abstract generic DOM manipulation; you should not inject them with application-specific services. In this case, it would be tempting to simply inject the locations
service into the directive, but this couples the directive to that service.
A brief aside on code modularity: a directive’s functions should almost never be responsible for getting or formatting their own data. There’s nothing to stop you from using the $http service from within a directive, but this is almost always the wrong thing to do. Writing a controller to use $http is the right way to do it. A directive already touches a DOM element, which is a very complex object and is difficult to stub out for testing. Adding network I/O to the mix makes your code that much more difficult to understand and that much more difficult to test. In addition, network I/O locks in the way that your directive will get its data – maybe in some other place you’ll want to have this directive receive data from a socket or take in preloaded data. Your directive should either take data in as an attribute through scope.$eval and/or have a controller to handle acquiring and storing the data.
In this specific case, you should place the appropriate data on your controller's scope and share it with the directive via an attribute.
app.controller('SomeController', function($scope, locations) {
locations().success(function(data) {
$scope.locations = data;
});
});
<ul class="list">
<li ng-repeat="location in locations">
<a href="#">{{location.id}}. {{location.name}}</a>
</li>
</ul>
<map locations='locations'></map>
app.directive('map', function() {
return {
restrict: 'E',
replace: true,
template: '<div></div>',
scope: {
// creates a scope variable in your directive
// called `locations` bound to whatever was passed
// in via the `locations` attribute in the DOM
locations: '=locations'
},
link: function(scope, element, attrs) {
scope.$watch('locations', function(locations) {
angular.forEach(locations, function(location, key) {
// do something
});
});
}
};
});
In this way, the map
directive can be used with any set of location data--the directive is not hard-coded to use a specific set of data, and simply linking the directive by including it in the DOM will not fire off random HTTP requests.
If everything is fine with your ConnectionString
check your DbSet collection name in you db context file. If that and database table names aren't matching you will also get this error.
So, for example, Categories, Products
public class ProductContext : DbContext
{
public DbSet<Category> Categories { get; set; }
public DbSet<Product> Products { get; set; }
}
should match with actual database table names:
just edit wp_user table with your phpmyadmin, and choose MD5 on Function field then input your new password, save it (go button).
Arrays.toString(int []) works for me.
here's what I found with my experiments using the built-in
FORMATMESSAGE() function
sp_addmessage @msgnum=50001,@severity=1,@msgText='Hello %s you are #%d',@replace='replace'
SELECT FORMATMESSAGE(50001, 'Table1', 5)
when you call up sp_addmessage, your message template gets stored into the system table master.dbo.sysmessages (verified on SQLServer 2000).
You must manage addition and removal of template strings from the table yourself, which is awkward if all you really want is output a quick message to the results screen.
The solution provided by Kathik DV, looks interesting but doesn't work with SQL Server 2000, so i altered it a bit, and this version should work with all versions of SQL Server:

HTML
<div id='a'>
<div>
<a class='click'>abc</a>
</div>
</div>
You could use the XPATH as :
//div[@id='a']//a[@class='click']
output
<a class="click">abc</a>
That said your Python code should be as :
driver.find_element_by_xpath("//div[@id='a']//a[@class='click']")
Simple:
st = "abcdefghij"
st = st[:-1]
There is also another way that shows how it is done with steps:
list1 = "abcdefghij"
list2 = list(list1)
print(list2)
list3 = list2[:-1]
print(list3)
This is also a way with user input:
list1 = input ("Enter :")
list2 = list(list1)
print(list2)
list3 = list2[:-1]
print(list3)
To make it take away the last word in a list:
list1 = input("Enter :")
list2 = list1.split()
print(list2)
list3 = list2[:-1]
print(list3)
For both Python 3 and Python 2, this works:
try:

except ImportError:
from urllib2 import Request, urlopen # Python 2
req = Request('http://api.company.com/items/details?country=US&language=en')
req.add_header('apikey', 'xxx')
content = urlopen(req).read()
print(content)

As has been said previously, assertions should be used when your code SHOULD NOT ever reach a point, meaning there is a bug there. Probably the most useful reason I can see to use an assertion is an invariant/pre/postcondition. These are something that must be true at the start or end of each iteration of a loop or a function.
For example, a recursive function (2 seperate functions so 1 handles bad input and the other handles bad code, cause it's hard to distinguish with recursion). This would make it obvious if I forgot to write the if statement, what had gone wrong.
def SumToN(n):
if n <= 0:
raise ValueError, "N must be greater than or equal to 0"
else:
return RecursiveSum(n)
def RecursiveSum(n):
#precondition: n >= 0
assert(n >= 0)
if n == 0:
return 0
return RecursiveSum(n - 1) + n
#postcondition: returned sum of 1 to n
These loop invariants often can be represented with an assertion.
In response to finding the max value for each column, you could try using the apply()

You need to set index=False
in to_excel
in order for it to not write the index column out, this semantic is followed in other Pandas IO tools, see http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_excel.html and http://pandas.pydata.org/pandas-docs/stable/io.html
Had the same issue with arrays, here is how to do it if you're manipulating arrays too :
array_name="ARRAY_NAME"
ARRAY_NAME=("Val0" "Val1" "Val2")
ARRAY=$array_name[@]
echo "ARRAY=${ARRAY}"
ARRAY=("${!ARRAY}")
echo "ARRAY=${ARRAY[@]}"
echo "ARRAY[0]=${ARRAY[0]}"
echo "ARRAY[1]=${ARRAY[1]}"
echo "ARRAY[2]=${ARRAY[2]}"
This will output :
ARRAY=ARRAY_NAME[@]
ARRAY=Val0 Val1 Val2
ARRAY[0]=Val0
ARRAY[1]=Val1
ARRAY[2]=Val2
None of these answers worked for me. I had to create my own function called alphanum which stripped the chars for me:
DROP FUNCTION IF EXISTS alphanum;
DELIMITER |
CREATE FUNCTION alphanum( str CHAR(255) ) RETURNS CHAR(255) DETERMINISTIC
BEGIN
DECLARE i, len SMALLINT DEFAULT 1;
DECLARE ret CHAR(255) DEFAULT '';
DECLARE c CHAR(1);
IF str IS NOT NULL THEN
SET len = CHAR_LENGTH( str );
REPEAT
BEGIN
SET c = MID( str, i, 1 );
IF c REGEXP '[[:alnum:]]' THEN
SET ret=CONCAT(ret,c);
END IF;
SET i = i + 1;
END;
UNTIL i > len END REPEAT;
ELSE
SET ret='';
END IF;
RETURN ret;
END |
DELIMITER ;
Now I can do:
select 'This works finally!', alphanum('This works finally!');
and I get:
+---------------------+---------------------------------+
| This works finally! | alphanum('This works finally!') |
+---------------------+---------------------------------+
| This works finally! | Thisworksfinally |
+---------------------+---------------------------------+

This has been asked before. .Net has a built-in ConvertAll function for converting between an array of one type to an array of another type. You can combine this with Split to separate the string to an array of strings
Example function:
static int[] ToIntArray(this string value, char separator)
{
return Array.ConvertAll(value.Split(separator), s=>int.Parse(s));
}
I think you are putting one too many curly brackets. Try this

@else
<td>{!! $user->status !!}</td>
@endif

}
return ds;

[LineNumbers]
enable = 1
enable_shell = 0

First of all, you probably don't want the align
environment if you have only one column of equations. In fact, your example is probably best with the cases
environment. But to answer your question directly, used the aligned
environment within equation
- this way the outside environment gives the number:
\begin{equation}
\begin{aligned}
w^T x_i + b &\geq 1-\xi_i &\text{ if }& y_i=1, \\
w^T x_i + b &\leq -1+\xi_i & \text{ if } &y_i=-1,
\end{aligned}
\end{equation}

1-firstly, drop the foreign key constraint after that drop the tables.
2-you can drop all foreign key via executing the following query:
DECLARE @SQL varchar(4000)=''
SELECT @SQL =
@SQL + 'ALTER TABLE ' + s.name+'.'+t.name + ' DROP CONSTRAINT [' + RTRIM(f.name) +'];' + CHAR(13)
FROM sys.Tables t
INNER JOIN sys.foreign_keys f ON f.parent_object_id = t.object_id
INNER JOIN sys.schemas s ON s.schema_id = f.schema_id
--EXEC (@SQL)
PRINT @SQL
if you execute the printed results @SQL, the foreign keys will be dropped.
The following will return true if the JTextField "name" does not contain text:

For a static library, the code is extracted from the library by the linker and used to build the the final executable at the point you compile/build your application. The final executable has no dependencies on the library at run time
For a shared library, the compiler/linker checks that the names you link with exist in the library when the application is built, but doesn't move their code into the application. At run time, the shared library must be available.
The C programming language itself has no concept of either static or shared libraries - they are completely an implementation feature.
Personally, I much prefer to use static libraries, as it makes software distribution simpler. However, this is an opinion over which much (figurative) blood has been shed in the past.

After editing the file, it's just a matter of clicking on Update Settings
button and it's done. I've just done it and it worked :)
if you are using GIT for control versions and in some of yours commit you added db.sqlite3, GIT will keep some references of the database, so when you execute 'python manage.py migrate', this reference will be reflected on the new database. I recommend to execute the following command:
git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch 'db.sqlite3' HEAD
it worked for me :)
Implementation:
// Promisify setTimeout
const pause = (ms, cb, ...args) =>
new Promise((resolve, reject) => {
setTimeout(async () => {
try {
resolve(await cb?.(...args))
} catch (error) {
reject(error)
}
}, ms)
})
Tests:
// Test 1
pause(1000).then(() => console.log('called'))
// Test 2
pause(1000, (a, b, c) => [a, b, c], 1, 2, 3).then(value => console.log(value))
// Test 3
pause(1000, () => {
throw Error('foo')
}).catch(error => console.error(error))
This a stab at creating a reusable column to comma separated string. In this case, I only one strings that have values and I do not want empty strings or nulls.
First I create a user defined type that is a one column table.
-- ================================
-- Create User-defined Table Type
-- ================================
USE [RSINET.MVC]
GO
-- Create the data type
CREATE TYPE [dbo].[SingleVarcharColumn] AS TABLE
(
data NVARCHAR(max)
)
GO
The real purpose of the type is to simplify creating a scalar function to put the column into comma separated values.
-- ================================================
-- Template generated from Template Explorer using:
-- Create Scalar Function (New Menu).SQL
--
-- Use the Specify Values for Template Parameters
-- command (Ctrl-Shift-M) to fill in the parameter
-- values below.
--
-- This block of comments will not be included in
-- the definition of the function.
-- ================================================
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author: Rob Peterson
-- Create date: 8-26-2015
-- Description: This will take a single varchar column and convert it to
-- comma separated values.
-- =============================================
CREATE FUNCTION fnGetCommaSeparatedString
(
-- Add the parameters for the function here
@column AS [dbo].[SingleVarcharColumn] READONLY
)
RETURNS VARCHAR(max)
AS
BEGIN
-- Declare the return variable here
DECLARE @result VARCHAR(MAX)
DECLARE @current VARCHAR(MAX)
DECLARE @counter INT
DECLARE @c CURSOR
SET @result = ''
SET @counter = 0
-- Add the T-SQL statements to compute the return value here
SET @c = CURSOR FAST_FORWARD
FOR SELECT COALESCE(data,'') FROM @column
OPEN @c
FETCH NEXT FROM @c
INTO @current
WHILE @@FETCH_STATUS = 0
BEGIN
IF @result <> '' AND @current <> '' SET @result = @result + ',' + @current
IF @result = '' AND @current <> '' SET @result = @current
FETCH NEXT FROM @c
INTO @current
END
CLOSE @c
DEALLOCATE @c
-- Return the result of the function
RETURN @result
END
GO
Now, to use this. I select the column I want to convert to a comma separated string into the SingleVarcharColumn Type.
DECLARE @s as SingleVarcharColumn
INSERT INTO @s VALUES ('rob')
INSERT INTO @s VALUES ('paul')
INSERT INTO @s VALUES ('james')
INSERT INTO @s VALUES (null)
INSERT INTO @s
SELECT iClientID FROM [dbo].tClient
SELECT [dbo].fnGetCommaSeparatedString(@s)
To get results like this.
rob,paul,james,1,9,10,11,12,13,14,15,16,18,19,23,26,27,28,29,30,31,32,34,35,36,37,38,39,40,41,42,44,45,46,47,48,49,50,52,53,54,56,57,59,60,61,62,63,64,65,66,67,68,69,70,71,72,74,75,76,77,78,81,82,83,84,87,88,90,91,92,93,94,98,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,120,121,122,123,124,125,126,127,128,129,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159
I made my data column in my SingleVarcharColumn type an NVARCHAR(MAX) which may hurt performance, but I flexibility was what I was looking for and it runs fast enough for my purposes. It would probably be faster if it were a varchar and if it had a fixed and smaller width, but I have not tested it.
¦ What is an attribute?
– A variable that belongs to an object.Attributes is same term used alternatively for properties or fields or data members or class members
¦ How else can it be called?
– field or instance variable
¦ How do you create one? What is the syntax?
– You need to declare attributes at the beginning of the class definition, outside of any method. The syntax is the following: ;
Regarding the error
'CREATE VIEW' must be the first statement in a query batch.
Microsoft SQL Server has a quirky reqirement that CREATE VIEW
be the only statement in a batch. This is also true of a few other statements, such as CREATE FUNCTION
. It is not true of CREATE TABLE
, so go figure …
The solution is to send your script to the server in small batches. One way to do this is to select a single statement and execute it. This is clearly inconvenient.
The more convenient solution is to get the client to send the script in small isolated batches.
The GO
keyword is not strictly an SQL command, which is why you can’t end it with a semicolon like real SQL commands. Instead it is an instruction to the client to break the script at this point and to send the portion as a batch.
As a result, you end up writing something like:
DROP VIEW IF EXISTS … ;
GO
CREATE VIEW … AS … ;
GO
None of the other database servers I have encountered (PostgreSQL, MySQL, Oracle, SQLite) have this quirk, so the requirement appears to be Microsoft Only.
Just go to the project Properties->Project Facets
Uncheck the dynamic module, click apply.
Maven->update the project.
After trying some ways to load the file with no success, I remembered I could use FileInputStream
, which worked perfectly.
InputStream is = new FileInputStream("file.txt");
This is another way to read a file into an InputStream
, it reads the file from the currently running folder.
Use the "has attribute" selector:
$('p[MyTag]')
Or to select one where that attribute has a specific value:
$('p[MyTag="Sara"]')
There are other selectors for "attribute value starts with", "attribute value contains", etc.
I wanted to work in VSO/TFS, then push publicly to GitHub when ready. Initial repo created in private VSO. When it came time to add to GitHub I did:
git remote add mygithubrepo https://github.com/jhealy/kinect2.git
git push -f mygithubrepo master
Worked like a champ...
For a sanity check, issue "git remote -v" to list the repositories associated with a project.
C:\dev\kinect\vso-repo-k2work\FaceNSkinWPF>git remote -v
githubrepo https://github.com/jhealy/kinect2.git (fetch)
githubrepo https://github.com/jhealy/kinect2.git (push)
origin https://devfish.visualstudio.com/DefaultCollection/_git/Kinect2Work (fetch)
origin https://devfish.visualstudio.com/DefaultCollection/_git/Kinect2Work (push)
Simple way, worked for me... Hope this helps someone.
Find missing all elements from array
int[] array = {3,5,7,8,2,1,32,5,7,9,30,5};
TreeMap<Integer, Integer> map = new TreeMap<>();
for(int i=0;i<array.length;i++) {
map.put(array[i], 1);
}
int maxSize = map.lastKey();
for(int j=0;j<maxSize;j++) {
if(null == map.get(j))
System.out.println("Missing `enter code here`No:"+j);
}
This is a feature, not a bug.
See http://docs.python.org/howto/unicode.html, specifically the 'unicode type' section.
After a long struggle, I found the solution.
Solution: Add a reference to System.Net.Http.Formatting.dll
. This assembly is also available in the C:\Program Files\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies folder.
The method ReadAsAsync
is an extension method declared in the class HttpContentExtensions
, which is in the namespace System.Net.Http
in the library System.Net.Http.Formatting
.
Reflector came to rescue!
SELECT
CASE
WHEN LastName IS NULL THEN FirstName
WHEN LastName IS NOT NULL THEN LastName + ', ' + FirstName
END AS 'FullName'
FROM
customers
GROUP BY
LastName,
FirstName
This works because the formula you use (the CASE statement) can never give the same answer for two different inputs.
This is not the case if you used something like:
LEFT(FirstName, 1) + ' ' + LastName
In such a case "James Taylor" and "John Taylor" would both result in "J Taylor".
If you wanted your output to have "J Taylor" twice (one for each person):
GROUP BY LastName, FirstName
If, however, you wanted just one row of "J Taylor" you'd want:
GROUP BY LastName, LEFT(FirstName, 1)
Check syntax and execute one command at a time, then verify output.
mysqldump -u remoteusername -p remotepassword -h your.site.com databasename > dump.sql
mysql -u localusername -p localpassword databasename < dump.sql
Once you've matched all passwords, you can use pipe.
Not in any conventional sense of the phrase "inside CSS."
You need to instantiate the MainViewModel and set it as datacontext. In your statement it just consider it as string value.
<Window x:Class="BuildAssistantUI.BuildAssistantWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:BuildAssistantUI.ViewModels">
<Window.DataContext>
<local:MainViewModel/>
</Window.DataContext>
So you use this:
var theDialog = $("#divDialog").dialog(opt);
theDialog.dialog("open");
and if you open a MVC Partial View in Dialog, you can create in index a hidden button and JQUERY click event:
$("#YourButton").click(function()
{
theDialog.dialog("open");
OR
theDialog.dialog("close");
});
then inside partial view html you call button trigger click like:
$("#YouButton").trigger("click")
see ya.
On a different note, it is also always a good practice to add a token to your form and verify it to check if the data was not sent from outside. Here are the steps:
Generate a unique token (you can use hash) Ex:
$token = hash (string $algo , string $data [, bool $raw_output = FALSE ] );
Assign this token to a session variable. Ex:
$_SESSION['form_token'] = $token;
Add a hidden input to submit the token. Ex:
input type="hidden" name="token" value="{$token}"
then as part of your validation, check if the submitted token matches the session var.
Ex: if ( $_POST['token'] === $_SESSION['form_token'] ) ....
Sku is an int, can't be defaulted to string "sku". Please check Optional URI Parameters and Default Values
That's because req
and res
are two different objects.
You need to look for the property on the same object you added it to.
Try something like this:
try {
$w = New-Object net.WebClient
$d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
Write-Host $_.Exception.ToString()
}
The exception is in the $_
variable. You might explore $_
like this:
try {
$w = New-Object net.WebClient
$d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
$_ | fl * -Force
}
I think it will give you all the info you need.
My rule: if there is some data that is not displayed, try to use -force
.
you can try these:
document.getElementById("RootNode").onclick = function(){/*do something*/};
or
$('#RootNode').click(function(){/*do something*/});
or
$(document).on("click", "#RootNode", function(){/*do something*/});
There is a point for the first two method which is, it matters where in your page DOM, you should put them, the whole DOM should be loaded, to be able to find the, which is usually it gets solved if you wrap them in a window.onload
or DOMReady
event, like:
//in Vanilla JavaScript
window.addEventListener("load", function(){
document.getElementById("RootNode").onclick = function(){/*do something*/};
});
//for jQuery
$(document).ready(function(){
$('#RootNode').click(function(){/*do something*/});
});
More recent and much cleaner: use event.key
. No more arbitrary number codes!
NOTE: The old properties (
.keyCode
and.which
) are Deprecated.
document.addEventListener('keydown', function(event) {
const key = event.key; // const {key} = event; ES6+
if (key === "Delete") {
// Do things
}
});
There are two variants of CASE
, and you're not using the one that you think you are.
CASE case_value
WHEN when_value THEN statement_list
[WHEN when_value THEN statement_list] ...
[ELSE statement_list]
END CASE
Each condition is loosely equivalent to a if (case_value == when_value)
(pseudo-code).
However, you've put an entire condition as when_value
, leading to something like:
if (case_value == (case_value > 100))
Now, (case_value > 100)
evaluates to FALSE
, and is the only one of your conditions to do so. So, now you have:
if (case_value == FALSE)
FALSE
converts to 0
and, through the resulting full expression if (case_value == 0)
you can now see why the third condition fires.
Drop the first course_enrollment_settings
so that there's no case_value
, causing MySQL to know that you intend to use the second variant of CASE
:
CASE
WHEN search_condition THEN statement_list
[WHEN search_condition THEN statement_list] ...
[ELSE statement_list]
END CASE
Now you can provide your full conditionals as search_condition
.
Also, please read the documentation for features that you use.
What you're asking for wouldn't make much sense. Unless I'm incorrect you're suggesting that you want to use XOR to perform Logical operations the same way AND and OR do. Your provided code actually shows what I'm reffering to:
public static boolean logicalXOR(boolean x, boolean y) {
return ( ( x || y ) && ! ( x && y ) );
}
Your function has boolean inputs, and when bitwise XOR is used on booleans the result is the same as the code you've provided. In other words, bitwise XOR is already efficient when comparing individual bits(booleans) or comparing the individual bits in larger values. To put this into context, in terms of binary values any non-zero value is TRUE and only ZERO is false.
So for XOR to be applied the same way Logical AND is applied, you would either only use binary values with just one bit(giving the same result and efficiency) or the binary value would have to be evaluated as a whole instead of per bit. In other words the expression ( 010 ^^ 110 ) = FALSE instead of ( 010 ^^ 110 ) = 100. This would remove most of the semantic meaning from the operation, and represents a logical test you shouldn't be using anyway.
Be sure you code sign on the line "any iOS SDK" and not "Debug/Distribution/Release"
Here is exactly what I did :
Code signing identity -> don't code sign
* Debug -> don't code sign
** any iOS SDK -> [my developer profile]
* Distribution -> don't code sign
** any iOS SDK -> [my AppStore profile]
* Release -> don't code sign
** any iOS SDK -> [my AdHoc profile]
When I put my profiles one level above (at Debug/Ditribution/Release), it doesn't work for some reason (bug ?).
Hope it helps some of us !
LinkedIn has updated their api and the sharing url's no longer works. Now you can only use the url
query parameter. Any other parameter is going to be removed from the url by LinkedIn.
Now you're forced to use oAuth and interact with the linkedin API to share content on behalf of a user.
To install 32-bit Java on Windows 7 (64-bit OS + Machine). You can do:
1) Download JDK: http://javadl.sun.com/webapps/download/AutoDL?BundleId=58124
2) Download JRE: http://www.java.com/en/download/installed.jsp?jre_version=1.6.0_22&vendor=Sun+Microsystems+Inc.&os=Linux&os_version=2.6.41.4-1.fc15.i686
3) System variable create: C:\program files (x86)\java\jre6\bin\
4) Anywhere you type java -version
it use 32-bit on (64-bit). I have to use this because lots of third party libraries do not work with 64-bit. Java wake up from the hell, give us peach :P. Go-language is killer.
What I did in the end is make a batch file to extract the CLASSPATH from the ant file, then run java directly using this:
In my build.xml:
<target name="printclasspath">
<pathconvert property="classpathProp" refid="project.class.path"/>
<echo>${classpathProp}</echo>
</target>
In another script called 'run.sh':
export CLASSPATH=$(ant -q printclasspath | grep echo | cut -d \ -f 7):build
java "$@"
It's no longer cross-platform, but at least it's relatively easy to use, and one could provide a .bat file that does the same as the run.sh. It's a very short batch script. It's not like migrating the entire build to platform-specific batch files.
I think it's a shame there's not some option in ant whereby you could do something like:
ant -- arg1 arg2 arg3
mpirun uses this type of syntax; ssh also can use this syntax I think.
If your whitespace is consistent you could use that as a delimiter, also instead of inserting \t
directly, you could set the output separator and it will be included automatically:
< file awk -v OFS='\t' -v FS='[/ ]' '{print $3, $5, $NF}'
@scanlegentil I like this.
A little improvement would be:
$Depth = 2
$Path = "."
$Levels = "\*" * $Depth
$Folder = Get-Item $Path
$FolderFullName = $Folder.FullName
Resolve-Path $FolderFullName$Levels | Get-Item | ? {$_.PsIsContainer} | Write-Host
As mentioned, this would only scan the specified depth, so this modification is an improvement:
$StartLevel = 1 # 0 = include base folder, 1 = sub-folders only, 2 = start at 2nd level
$Depth = 2 # How many levels deep to scan
$Path = "." # starting path
For ($i=$StartLevel; $i -le $Depth; $i++) {
$Levels = "\*" * $i
(Resolve-Path $Path$Levels).ProviderPath | Get-Item | Where PsIsContainer |
Select FullName
}
Assuming that the input string in your example (????) is a UTF-8 encoded (which it isn't, by the looks of it, but let's assume it is for the sake of this explanation :-)) representation of a Unicode string of your interest, then your problem can be fully solved with the standard library (C++11 and newer) alone.
The TL;DR version:
#include <locale>
#include <codecvt>
#include <string>
std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> converter;
std::string narrow = converter.to_bytes(wide_utf16_source_string);
std::wstring wide = converter.from_bytes(narrow_utf8_source_string);
Longer online compilable and runnable example:
(They all show the same example. There are just many for redundancy...)
Note (old):
As pointed out in the comments and explained in https://stackoverflow.com/a/17106065/6345 there are cases when using the standard library to convert between UTF-8 and UTF-16 might give unexpected differences in the results on different platforms. For a better conversion, consider std::codecvt_utf8
as described on http://en.cppreference.com/w/cpp/locale/codecvt_utf8
Note (new):
Since the codecvt
header is deprecated in C++17, some worry about the solution presented in this answer were raised. However, the C++ standards committee added an important statement in http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0618r0.html saying
this library component should be retired to Annex D, along side , until a suitable replacement is standardized.
So in the foreseeable future, the codecvt
solution in this answer is safe and portable.
How can I undo every change made to my directory after the last commit, including deleting added files, resetting modified files, and adding back deleted files?
You can undo changes to tracked files with:
git reset HEAD --hard
You can remove untracked files with:
git clean -f
You can remove untracked files and directories with:
git clean -fd
but you can't undo change to untracked files.
You can remove ignored and untracked files and directories
git clean -fdx
but you can't undo change to ignored files.
You can also set clean.requireForce
to false
:
git config --global --add clean.requireForce false
to avoid using -f
(--force
) when you use git clean
.
Your HTML and the way you call the function from the button look correct.
The problem appears to be in the CapacityCount
function. I'm getting this error in my console on Firefox 3.5: "document.all is undefined" on line 759 of bendelcorp.js.
Edit:
Looks like document.all
is an IE-only thing and is a nonstandard way of accessing the DOM. If you use document.getElementById()
, it should probably work. Example: document.getElementById("RUnits").value
instead of document.all.Capacity.RUnits.value
To my surprise, potrace it turns out, can only process black and white. That may be fine for you use case, but some may consider lack of color tracing to be problematic.
Personally, I've had satisfactory results with Vector Magic
Still it's not perfect.
You were on the right track. IrfanView sets the background for transparency the same as the viewing color around the image.
You just need to re-open the image with IrfanView after changing the view color to white.
To change the viewing color in Irfanview go to:
Options > Properties/Settings > Viewing > Main window color
Although recently its use is undefined, a common and useful use for the form feed is to separate sections of code vertically, like so: (from http://ergoemacs.org/emacs/emacs_form_feed_section_paging.html)
Create a file named "config.js" in ./src folder with this content:
module.exports = global.config = {
i18n: {
welcome: {
en: "Welcome",
fa: "??? ?????"
}
// rest of your translation object
}
// other global config variables you wish
};
In your main file "index.js" put this line:
import './config';
Everywhere you need your object use this:
global.config.i18n.welcome.en
You can also reset page number counter:
\setcounter{page}{1}
However, with this technique you get wrong page numbers in Acrobat in the top left page numbers field:
\maketitle: 1
\tableofcontents: 2
\setcounter{page}{1}
\section{Introduction}: 1
...
A very simple way of doing this is to use reset_index() method.For a data frame df use the code below:
df.reset_index(inplace=True)
This way, the index will become a column, and by using inplace as True,this become permanent change.
It is crude, but you can open up the Javascript console in Chrome (Ctrl+Shift+J) and paste the text contents of the *.js file and hit Enter.
This worked best for me.
git rebase -X ours -i master
This will git will prefer your feature branch to master; avoiding the arduous merge edits. Your branch needs to be up to date with master.
ours
This resolves any number of heads, but the resulting tree of the merge is always that of the current
branch head, effectively ignoring all changes from all other branches. It is meant to be used to
supersede old development history of side branches. Note that this is different from the -Xours
option to the recursive merge strategy.
Use robocopy
. Robocopy is shipped by default on Windows Vista and newer, and is considered the replacement for xcopy
. (xcopy
has some significant limitations, including the fact that it can't handle paths longer than 256 characters, even if the filesystem can).
robocopy c:\ d:\ /e /zb /copyall /purge /dcopy:dat
Note that using /purge
on the root directory of the volume will cause Robocopy to apply the requested operation on files inside the System Volume Information directory. Run robocopy /?
for help. Also note that you probably want to open the command prompt as an administrator to be able to copy system files. To speed things up, use /b
instead of /zb
.
You can do it programmatically like
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editTextField.getWindowToken(), 0);
or set android:windowSoftInputMode="stateHidden"
in <activity tag
inside AndroidManifest.xml
Try this instead of your code:
var type=$("#the-span").attr("data-type");
alert(type);
I like how this guy does it — https://amalgjose.com/2015/02/19/python-code-for-calculating-the-difference-between-two-time-stamps. Not sure if it has some cons.
But looks neat for me :)
from datetime import datetime
from dateutil.relativedelta import relativedelta
t_a = datetime.now()
t_b = datetime.now()
def diff(t_a, t_b):
t_diff = relativedelta(t_b, t_a) # later/end time comes first!
return '{h}h {m}m {s}s'.format(h=t_diff.hours, m=t_diff.minutes, s=t_diff.seconds)
Regarding to the question you still need to use datetime.strptime()
as others said earlier.
Browsers can often tell the image type by sniffing out the meta information of the image. Also, there should be a space in that header:
header('Content-type: image/png');
If you want to transform a number into another number (not number to string of characters), and you can do with a small range (0 to 1023 for implementations with 32-bit integers), you don't need to add char*
to the solution
unsigned int_to_int(unsigned k) {
if (k == 0) return 0;
if (k == 1) return 1; /* optional */
return (k % 2) + 10 * int_to_int(k / 2);
}
HalosGhost suggested to compact the code into a single line
unsigned int int_to_int(unsigned int k) {
return (k == 0 || k == 1 ? k : ((k % 2) + 10 * int_to_int(k / 2)));
}
For me the accepted answer for adding export PATH=/usr/local/share/npm/bin:$PATH
to .zshrc
didn't work. I tried adding the NVM_DIR
as well which solved my issue.
vi .bashrc
You will find a line like the following. Copy it.
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Paste the copied content to .zshrc
file
I hope this solves your issue.
do not forget to do it with parse html. like:
$.ajax({
url: url,
cache: false,
success: function(response) {
var parsed = $.parseHTML(response);
result = $(parsed).find("#result");
}
});
has to work :)
This only works on Windows, so if you are planning to use dotnet core cross-platform, you'll have to look elsewhere. See https://github.com/dotnet/corefx/blob/master/Documentation/architecture/cross-platform-cryptography.md
To compare two objects you can use:
angular.equals(obj1, obj2)
It does a deep comparison and does not depend on the order of the keys See AngularJS DOCS and a little Demo
var obj1 = {
key1: "value1",
key2: "value2",
key3: {a: "aa", b: "bb"}
}
var obj2 = {
key2: "value2",
key1: "value1",
key3: {a: "aa", b: "bb"}
}
angular.equals(obj1, obj2) //<--- would return true
If you know the list of ids try this query:
SELECT * FROM `Buses` WHERE BusId IN (`list of busIds`)
or if you pull them from another table list of busIds
could be another subquery:
SELECT * FROM `Buses` WHERE BusId IN (SELECT SomeId from OtherTable WHERE something = somethingElse)
If you need to compare to another table you need a join:
SELECT * FROM `Buses` JOIN OtheTable on Buses.BusesId = OtehrTable.BusesId
I faced the same issue below is the working code :
$("#test option").filter(function() {
return $(this).text() =='Ford';
}).prop("selected", true);
I tried this and worked for me.
Date = (long)(DateTime.Now.Subtract(new DateTime(1970, 1, 1, 0, 0, 0))).TotalSeconds
I recently published a project that allows PHP to obtain and interact with a real Bash shell. Get it here: https://github.com/merlinthemagic/MTS The shell has a pty (pseudo terminal device, same as you would have in i.e. a ssh session), and you can get the shell as root if desired. Not sure you need root to execute your script, but given you mention sudo it is likely.
After downloading you would simply use the following code:
$shell = \MTS\Factories::getDevices()->getLocalHost()->getShell('bash', true);
$return1 = $shell->exeCmd('/path/to/osascript myscript.scpt');
find "${search_dir}" "${work_dir}" -mindepth 1 -maxdepth 1 -type f -print0 | xargs -0 -I {} echo "{}"
As a modification to crazylammer's answer, I often use:
your_vector_type::iterator it;
for( it = res.start(); it != res.end();)
{
your_vector_type::iterator curr = it++;
if (something)
res.erase(curr);
}
The advantage of this is that you don't have to worry about forgetting to increment your iterator, making it less bug prone when you have complex logic. Inside the loop, curr will never be equal to res.end(), and it will be at the next element regardless of if you erase it from your vector.
If you want to fetch particular element/node or tag in loop for e.g.
<p class="weekday" data-today="monday">Monday</p>
<p class="weekday" data-today="tuesday">Tuesday</p>
<p class="weekday" data-today="wednesday">Wednesday</p>
<p class="weekday" data-today="thursday">Thursday</p>
So, from above code loop is executed and we want particular field to select for that we have to use jQuery selection that can select only expecting element from above loop so, code will be
$('.weekdays:eq(n)');
e.g.
$('.weekdays:eq(0)');
as well as by other method
$('.weekday').find('p').first('.weekdays').next()/last()/prev();
but first method is more efficient when HTML <tag>
has unique class name.
NOTE:Second method is use when their is no class name in target element or node.
for more follow https://api.jquery.com/eq/
add:
Chart.defaults.global.legend.display = false;
in the starting of your script code;
Here's how I find valid 10-digit US phone numbers. At this point I'm assuming the user wants my content so the numbers themselves are trusted. I'm using in an app that ultimately sends an SMS message so I just want the raw numbers no matter what. Formatting can always be added later
//eliminate every char except 0-9
$justNums = preg_replace("/[^0-9]/", '', $string);
//eliminate leading 1 if its there
if (strlen($justNums) == 11) $justNums = preg_replace("/^1/", '',$justNums);
//if we have 10 digits left, it's probably valid.
if (strlen($justNums) == 10) $isPhoneNum = true;
Edit: I ended up having to port this to Java, if anyone's interested. It runs on every keystroke so I tried to keep it fairly light:
boolean isPhoneNum = false;
if (str.length() >= 10 && str.length() <= 14 ) {
//14: (###) ###-####
//eliminate every char except 0-9
str = str.replaceAll("[^0-9]", "");
//remove leading 1 if it's there
if (str.length() == 11) str = str.replaceAll("^1", "");
isPhoneNum = str.length() == 10;
}
Log.d("ISPHONENUM", String.valueOf(isPhoneNum));
If you want to place the cursor in a certain position on an EditText, you can use:
yourEditText.setSelection(position);
Additionally, there is the possibility to set the initial and final position, so that you programmatically select some text, this way:
yourEditText.setSelection(startPosition, endPosition);
Please note that setting the selection might be tricky since you can place the cursor before or after a character, the image below explains how to index works in this case:
So, if you want the cursor at the end of the text, just set it to yourEditText.length()
.
You can try this
$('.checkAll').on('click',function(){
$('.checkboxes').prop('checked',$(this).prop("checked"));
});`
Class .checkAll
is a checkbox which controls the bulk action
Supplemental answer
I was originally having trouble getting a reference to the ViewPager
from other class methods because the addOnTabSelectedListener
made an anonymous inner class, which in turn required the ViewPager
variable to be declared final
. The solution was to use a class member variable and not use the anonymous inner class.
public class MainActivity extends AppCompatActivity {
TabLayout tabLayout;
ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
// don't use an anonymous inner class here
tabLayout.addOnTabSelectedListener(tabListener);
}
TabLayout.OnTabSelectedListener tabListener = new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
};
// The view pager can now be accessed here, too.
public void someMethod() {
viewPager.setCurrentItem(0);
}
}
The @ symbol denotes an annotation type definition.
That means it is not really an interface, but rather a new annotation type -- to be used as a function modifier, such as @override.
See this javadocs entry on the subject.
I think that the simplest solutions of all, it's just a quick fix, but you can delete, comment the Application.EnableVisualStyles() from Program.cs, or however you have name your the part containing the Main function. After that you can freely change the color form the progress bar by progressBar.ForeColor = Color.TheColorYouDesire;
static void Main()
{
//Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}

Row Size Limits
The maximum row size for a given table is determined by several factors:
The internal representation of a MySQL table has a maximum row size limit of 65,535 bytes, even if the storage engine is capable of supporting larger rows. BLOB and TEXT columns only contribute 9 to 12 bytes toward the row size limit because their contents are stored separately from the rest of the row.
The maximum row size for an InnoDB table, which applies to data stored locally within a database page, is slightly less than half a page for 4KB, 8KB, 16KB, and 32KB innodb_page_size settings. For example, the maximum row size is slightly less than 8KB for the default 16KB InnoDB page size. For 64KB pages, the maximum row size is slightly less than 16KB. See Section 15.8.8, “Limits on InnoDB Tables”.
If a row containing variable-length columns exceeds the InnoDB maximum row size, InnoDB selects variable-length columns for external off-page storage until the row fits within the InnoDB row size limit. The amount of data stored locally for variable-length columns that are stored off-page differs by row format. For more information, see Section 15.11, “InnoDB Row Storage and Row Formats”.
Different storage formats use different amounts of page header and trailer data, which affects the amount of storage available for rows.
For information about InnoDB row formats, see Section 15.11, “InnoDB Row Storage and Row Formats”, and Section 15.8.3, “Physical Row Structure of InnoDB Tables”.
For information about MyISAM storage formats, see Section 16.2.3, “MyISAM Table Storage Formats”.

There's no exact counterpart to Java's getClass()
in JavaScript. Mostly that's due to JavaScript being a prototype-based language, as opposed to Java being a class-based one.
Depending on what you need getClass()
for, there are several options in JavaScript:
typeof
instanceof
obj.
constructor
func.
prototype
, proto
.isPrototypeOf
A few examples:
function Foo() {}
var foo = new Foo();
typeof Foo; // == "function"
typeof foo; // == "object"
foo instanceof Foo; // == true
foo.constructor.name; // == "Foo"
Foo.name // == "Foo"
Foo.prototype.isPrototypeOf(foo); // == true
Foo.prototype.bar = function (x) {return x+x;};
foo.bar(21); // == 42
Note: if you are compiling your code with Uglify it will change non-global class names. To prevent this, Uglify has a --mangle
param that you can set to false is using gulp or grunt.
pylab
, not matplotlib.pyplot
You may try using hist
to put your data info along with the fitted curve as below:
import numpy as np
import scipy.stats as stats
import pylab as pl
h = sorted([186, 176, 158, 180, 186, 168, 168, 164, 178, 170, 189, 195, 172,
187, 180, 186, 185, 168, 179, 178, 183, 179, 170, 175, 186, 159,
161, 178, 175, 185, 175, 162, 173, 172, 177, 175, 172, 177, 180]) #sorted
fit = stats.norm.pdf(h, np.mean(h), np.std(h)) #this is a fitting indeed
pl.plot(h,fit,'-o')
pl.hist(h,normed=True) #use this to draw histogram of your data
pl.show() #use may also need add this
DDL stands for Data Definition Language. DDL is used for defining structure of the table such as create a table or adding a column to table and even drop and truncate table. DML stands for Data Manipulation Language. As the name suggest DML used for manipulating the data of table. There are some commands in DML such as insert and delete.
Here is a better implementation of an "every 10th item" list comprehension, that does not use the list contents as part of the membership test:
>>> l = range(165)
>>> [ item for i,item in enumerate(l) if i%10==0 ]
[0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160]
>>> l = list("ABCDEFGHIJKLMNOPQRSTUVWXYZ")
>>> [ item for i,item in enumerate(l) if i%10==0 ]
['A', 'K', 'U']
But this is still far slower than just using list slicing.
I just published this module because I needed this functionality.

It works like a wrapper around Node.js fs methods. So you can use it exactly the same way you would with fs.writeFile
and fs.writeFileSync
(both async and synchronous writes)
While you can use a virtualenv
, you don't need to. The trick is passing the PEP370 --user
argument to the setup.py
script. With the latest version of pip
, one way to do it is:
pip install --user mercurial
This should result in the hg
script being installed in $HOME/.local/bin/hg
and the rest of the hg package in $HOME/.local/lib/pythonx.y/site-packages/
.
Note, that the above is true for Python 2.6. There has been a bit of controversy among the Python core developers about what is the appropriate directory location on Mac OS X for PEP370-style user
installations. In Python 2.7 and 3.2, the location on Mac OS X was changed from $HOME/.local
to $HOME/Library/Python
. This might change in a future release. But, for now, on 2.7 (and 3.2, if hg
were supported on Python 3), the above locations will be $HOME/Library/Python/x.y/bin/hg
and $HOME/Library/Python/x.y/lib/python/site-packages
.
1. First should understand the error meaning
Error not enough values to unpack (expected 3, got 2)
means:
a 2 part tuple, but assign to 3 values
and I have written demo code to show for you:
#!/usr/bin/python

notEnoughUnpack()
using VSCode
debug effect:
2. For your code
for name, email, lastname in unpaidMembers.items():
but error
ValueError: not enough values to unpack (expected 3, got 2)
means each item(a tuple value) in unpaidMembers
, only have 1 parts:email
, which corresponding above code
unpaidMembers[name] = email
so should change code to:
for name, email in unpaidMembers.items():
to avoid error.
But obviously you expect extra lastname
, so should change your above code to
unpaidMembers[name] = (email, lastname)
and better change to better syntax:
for name, (email, lastname) in unpaidMembers.items():
then everything is OK and clear.
Though both @pkozlowski.opensource's and @Mark's answers are correct, I'd like to share my slightly modified version where I always select the first item in the list, regardless of its value:
<select ng-options="option.value as option.name for option in typeOptions" ng-init="form.type=typeOptions[0].value">
</select>
Since the number of digits in base 10 of an integer is just 1 + truncate(log10(number)), you can do:
public class Test {
public static void main(String[] args) {
final int number = 1234;
final int digits = 1 + (int)Math.floor(Math.log10(number));
System.out.println(digits);
}
}
Edited because my last edit fixed the code example, but not the description.
Just be careful. You will get this message if you try to enter a command that doesn't exist like this

just change your JDK I installed the JDK of SUN not Oracle and it works for me....
The solution to when you're using XMLWriter
(native to PHP 5.2.x
<) is using $xml->startElement('itemName');
this will replace the arrays key.
You may have a look at these slides from the last italian pycon (pdf): The author listed most of the library for doing scraping and autoted browsing in python. so you may have a look at it.
I like very much twill (which has already been suggested), which has been developed by one of the authors of nose and it is specifically aimed at testing web sites.
Your student.h file only forward declares a struct named "Student", it does not define one. This is sufficient if you only refer to it through reference or pointer. However, as soon as you try to use it (including creating one) you will need the full definition of the structure.
In short, move your struct Student { ... }; into the .h file and use the .cpp file for implementation of member functions (which it has none so you don't need a .cpp file).
You can install boost on ubuntu by using the following commands:
sudo apt update
sudo apt install libboost-all-dev
On Linux with Inkscape 1.0 to convert from svg to png need to use
inkscape -w 1024 -h 1024 input.svg --export-file output.png
not
inkscape -w 1024 -h 1024 input.svg --export-filename output.png
TLDR; Here's why:
The reason this works is because
gulp
tries to run yourgulpfile.js
using your locally installed version ofgulp
, see here. Hence the reason for a global and local install of gulp.
Essentially, when you install gulp
locally the script isn't in your PATH
and so you can't just type gulp
and expect the shell to find the command. By installing it globally the gulp
script gets into your PATH
because the global node/bin/
directory is most likely on your path.
To respect your local dependencies though, gulp
will use your locally installed version of itself to run the gulpfile.js
.
Yes you can view XML
files of an Android APK
file. There is a tool for this: android-apktool
It is a tool for reverse engineering 3rd party, closed, binary Android apps
How to do this on your Windows System:
Now copy the APK
file also in that directory and run the following command in your command prompt:
apktool d HelloWorld.apk ./HelloWorld
This will create a directory "HelloWorld
" in your current directory. Inside it you can find the AndroidManifest.xml
file in decrypted format, and you can also find other XML
files inside the "HelloWorld/res/layout"
directory.
Here HelloWorld.apk
is your Android APK file.
See the below screen shot for more information:
you might be referring two jquery scripts which is giving the above error.
Go to following path Control Panel>>System and Security>>System>>Advance system settings>>Environment Variables then set the variable value of ANDROID_HOME set it like following "C:\Users\username\AppData\Local\Android\sdk" set the username as your pc name, then just restart your android studio. Then you can create your AVD again after that your error will be gone and it will start the virtual device.
Incrementing on @Nilesh's answer (credit goes to him), you can:
This is UNTESTED sample code to show the idea, it could also be wrapped into a class:
const unsigned int size=10; // ten elements buffer
unsigned int counterPosition=0;
unsigned int counterNum=0;
int buffer[size];
long sum=0;
void reset() {
for(int i=0;i<size;i++) {
buffer[i]=0;
}
}
float addValue(int value) {
unsigned int oldPos = ((counterPosition + 1) % size);
buffer[counterPosition] = value;
sum = (sum - buffer[oldPos] + value);
counterPosition=(counterPosition+1) % size;
if(counterNum<size) counterNum++;
return ((float)sum)/(float)counterNum;
}
float removeValue() {
unsigned int oldPos =((counterPosition + 1) % size);
buffer[counterPosition] = 0;
sum = (sum - buffer[oldPos]);
if(counterNum>1) { // leave one last item at the end, forever
counterPosition=(counterPosition+1) % size;
counterNum--; // here the two counters are different
}
return ((float)sum)/(float)counterNum;
}
It should be noted that, if the buffer is reset to all zeroes, this method works fine while receiving the first values in as - buffer[oldPos] is zero and counter grows. First output is the first number received. Second output is the average of only the first two, and so on, fading in the values while they arrive until size
items are reached.
It is also worth considering that this method, like any other for rolling average, is asymmetrical, if you stop at the end of the input array, because the same fading does not happen at the end (it can happen after the end of data, with the right calculations).
That is correct. The rolling average of 100 elements with a buffer of 10 gives different results: 10 fading in, 90 perfectly rolling 10 elements, and finally 10 fading out, giving a total of 110 results for 100 numbers fed in! It's your choice to decide which ones to show (and if it's better going the straight way, old to recent, or backwards, recent to old).
To fade out correctly after the end, you can go on adding zeroes one by one and reducing the count of items by one every time until you have reached size
elements (still keeping track of correct position of old values).
Usage is like this:
int avg=0;
reset();
avg=addValue(2); // Rpeat for 100 times
avg=addValue(3); // Use avg value
...
avg=addValue(-4);
avg=addValue(12); // last numer, 100th input
// If you want to fade out repeat 10 times after the end of data:
avg=removeValue(); // Rpeat for last 10 times after data has finished
avg=removeValue(); // Use avg value
...
avg=removeValue();
avg=removeValue();
When you want a flex item to occupy an entire row, set it to width: 100%
or flex-basis: 100%
, and enable wrap
on the container.
The item now consumes all available space. Siblings are forced on to other rows.
.parent {
display: flex;
flex-wrap: wrap;
}
#range, #text {
flex: 1;
}
.error {
flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
border: 1px dashed black;
}
_x000D_
<div class="parent">
<input type="range" id="range">
<input type="text" id="text">
<label class="error">Error message (takes full width)</label>
</div>
_x000D_
More info: The initial value of the flex-wrap
property is nowrap
, which means that all items will line up in a row. MDN
Another option that I recently stumbled on is this:
{
echo "First error line"
echo "Second error line"
echo "Third error line"
} >&2
This uses only Bash built-ins while making multi-line error output less error prone (since you don't have to remember to add &>2
to every line).

Since I have recently developed an Android application using gyroscope data (steady compass), I tried to collect a list with such devices. This is not an exhaustive list at all, but it is what I have so far:
*** Phones:
*** Tablets:
Hope the list keeps growing and hope that gyros will be soon available on mid and low price smartphones.
You can open the file using the ios::ate
flag (and ios::binary
flag), so the tellg()
function will give you directly the file size:
ifstream file( "example.txt", ios::binary | ios::ate);
return file.tellg();
Please add these 2 simple line of code:
self.YourViewName.layer.cornerRadius = 15
self.YourViewName.layer.masksToBounds = true
It will work fine.
This should work for you. It just passes {:value => params[:pid] }
to the html_options variable.
<%= f.select :project_id, @project_select, {}, {:value => params[:pid] } %>
If your using Visual Studio just run the application with Crtl + F5 instead of F5. This will leave the console open when it's finished executing.

Hibernate 4.3 is the first version to implement the JPA 2.1 spec (part of Java EE 7). And it's thus expecting the JPA 2.1 library in the classpath, not the JPA 2.0 library. That's why you get this exception: Table.indexes() is a new attribute of Table, introduced in JPA 2.1
Make sure your article:author data is a Facebook author URL. Unfortunately, that conflicts with what Pinterest is expecting. It's the best thing about standards, there are so many ways to implement them!
<meta property="article:author" content="https://www.facebook.com/mpatnode76">
But Pinterest wants to see something like this:

Add below line to file where error is being thrown.This should fix the issue
declare var Promise: any;
P.S: This is definitely not the optimal solution

Make sure Your TableView Delegate are working as well. if not then in your story board or in .xib press and hold Control + right click on tableView drag and Drop to your Current ViewController. swift 2.0
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {

I just had the same error message.
I have a separate project for my data access. Running the Web Project (which referenced the data project) locally worked just fine. But when I deployed the web project to azure the assembly: EntityFramework.SqlServer was not copied. I just added the reference to the web project and redeployed, now it works.
hope this helps others
You can also call the show() function after each plot. e.g
plt.plot(a)
plt.show()
plt.plot(b)
plt.show()
Use the website mentioned in previous posts to create the icons:http://android-ui-utils.googlecode.com/hg/asset-studio/dist/index.html Unzip folder and Go into you file explorer on (windows or mac) find AndroidStudioProjects > "app name" > app > src > main (replace the web one here)> res (replace the rest with the one from the unzipped folder the you already downloaded)

A single line method within bash works like this.
[some out put] >$(date "+%Y.%m.%d-%H.%M.%S").ver
will create a file with a timestamp name with ver extension. A working file listing snap shot to a date stamp file name as follows can show it working.
find . -type f -exec ls -la {} \; | cut -d ' ' -f 6- >$(date "+%Y.%m.%d-%H.%M.%S").ver
Of course
cat somefile.log > $(date "+%Y.%m.%d-%H.%M.%S").ver
or even simpler
ls > $(date "+%Y.%m.%d-%H.%M.%S").ver
In Windows, you can use the msvcrt
module.
msvcrt.kbhit() Return true if a keypress is waiting to be read.
msvcrt.getch() Read a keypress and return the resulting character. Nothing is echoed to the console. This call will block if a keypress is not already available, but will not wait for Enter to be pressed.
If you want it to also work on Unix-like systems you can try this solution using the termios and fcntl modules.
I used Retrofit 2.0 for my register users, send multipart/form File image and text from register account
In my RegisterActivity, use an AsyncTask
//AsyncTask
private class Register extends AsyncTask<String, Void, String> {
@Override
protected void onPreExecute() {..}
@Override
protected String doInBackground(String... params) {
new com.tequilasoft.mesasderegalos.dbo.Register().register(txtNombres, selectedImagePath, txtEmail, txtPassword);
responseMensaje = StaticValues.mensaje ;
mensajeCodigo = StaticValues.mensajeCodigo;
return String.valueOf(StaticValues.code);
}
@Override
protected void onPostExecute(String codeResult) {..}

set -x
Prints a trace of simple commands, for commands, case commands, select commands, and arithmetic for commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4 variable is expanded and the resultant value is printed before the command and its expanded arguments.
[source]
set -x
echo `expr 10 + 20 `
+ expr 10 + 20
+ echo 30
30
set +x
echo `expr 10 + 20 `
30
Above example illustrates the usage of set -x
. When it is used, above arithmetic expression has been expanded. We could see how a singe line has been evaluated step by step.

when it comes to your shell script,

The code from Alex works great. Just note that when you use request.getParameter you must use a request dispatcher
//Pass results back to the client
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("TestPages/ServiceServlet.jsp");
dispatcher.forward(request, response);
The problem with your macro is that once you have opened your destination Workbook (xlw
in your code sample), it is set as the ActiveWorkbook object and you get an error because TextBox1 doesn't exist in that specific Workbook. To resolve this issue, you could define a reference object to your actual Workbook before opening the other one.
Sub UploadData()
Dim xlo As New Excel.Application
Dim xlw As New Excel.Workbook
Dim myWb as Excel.Workbook
Set myWb = ActiveWorkbook
Set xlw = xlo.Workbooks.Open("c:\myworkbook.xlsx")
xlo.Worksheets(1).Cells(2, 1) = myWb.ActiveSheet.Range("d4").Value
xlo.Worksheets(1).Cells(2, 2) = myWb.ActiveSheet.TextBox1.Text
xlw.Save
xlw.Close
Set xlo = Nothing
Set xlw = Nothing
End Sub
If you prefer, you could also use myWb.Activate
to put back your main Workbook as active. It will also work if you do it with a Worksheet object. Using one or another mostly depends on what you want to do (if there are multiple sheets, etc.).
The documentation for writelines()
states:
writelines()
does not add line separators
So you'll need to add them yourself. For example:
line_list.append(new_line + "\n")
whenever you append a new item to line_list
.
I think you have a couple of options here.
you could store the last Exception in the Session and retrieve it from your custom error page; or you could just redirect to your custom error page within the Application_error event. If you choose the latter, you want to make sure you use the Server.Transfer method.
You need to do this:
exec procName
@parameter_1_Name = 'parameter_1_Value',
@parameter_2_name = 'parameter_2_value',
@parameter_z_name = 'parameter_z_value'
myBook.Saved = true;
myBook.SaveCopyAs(xlsFileName);
myBook.Close(null, null, null);
myExcel.Workbooks.Close();
myExcel.Quit();
Depending on the level of precision you require you can work it out yourself, using the simple proof of differentiation:
>>> (((5 + 0.1) ** 2 + 1) - ((5) ** 2 + 1)) / 0.1
10.09999999999998
>>> (((5 + 0.01) ** 2 + 1) - ((5) ** 2 + 1)) / 0.01
10.009999999999764
>>> (((5 + 0.0000000001) ** 2 + 1) - ((5) ** 2 + 1)) / 0.0000000001
10.00000082740371
we can't actually take the limit of the gradient, but its kinda fun. You gotta watch out though because
>>> (((5+0.0000000000000001)**2+1)-((5)**2+1))/0.0000000000000001
0.0
How about something like
CREATE TABLE testRequest (
wardNo nchar(5),
BHTNo nchar(5),
testID nchar(5),
reqDateTime datetime,
PRIMARY KEY (wardNo, BHTNo, testID)
);
Have a look at this example
Just simple modification of @silgon answer:

To delete a job which has not yet run, you need the atrm
command. You can use atq
command to get its number in the at list.
To kill a job which has already started to run, you'll need to grep for it using:
ps -eaf | grep <command name>
and then use kill
to stop it.
A quicker way to do this on most systems is:
pkill <command name>
You can also try recfromcsv()
which can guess data types and return a properly formatted record array.
I can't find anything that deals with clock times exactly, so I'd just use some functions from package:lubridate and work with seconds-since-midnight:
require(lubridate)
clockS = function(t){hour(t)*3600+minute(t)*60+second(t)}
plot(clockS(times),val)
You might then want to look at some of the axis code to figure out how to label axes nicely.
Use can use CSS too, add focus and active (for IE7 and under) to the hidden link. Example of a ul menu inside a div with class menu:
.menu ul ul {display:none; position:absolute; left:100%; top:0; padding:0;}
.menu ul ul ul {display:none; position:absolute; top:0; left:100%;}
.menu ul ul a, .menu ul ul a:focus, .menu ul ul a:active { width:170px; padding:4px 4%; background:#e77776; color:#fff; margin-left:-15px; }
.menu ul li:hover > ul { display:block; }
.menu ul li ul li {margin:0;}
It's late and untested, should work ;-)

Since this would be a common task I would suggest wrapping a switch/case inside of a function call.
function getVocationName($vocation){
switch($vocation){
case 1: return "Sorcerer";
case 2: return 'Druid';
case 3: return 'Paladin';
case 4: return 'Knight';
case 5: return 'Master Sorcerer';
case 6: return 'Elder Druid';
case 7: return 'Royal Paladin';
default: return 'Elite Knight';
}
}
echo getVocationName($result->vocation);
you can set a password to your vba code but this can be quite easily broken up.
you can also create an addin and compile it into a DLL. See here for more information. That's at least the most secure way to protect your code.
Regards,
Old question but recently I seemed to be running into same issue with thumbnail images from my link not showing in status updates on Facebook. I post for many clients and this is relatively new.
FB doesn't seem to like long URLs anymore — if you use a URL shortener such as goo.gl or bitly.com, the thumbnail from your link/post will appear in your FB update.
I had this problem and tried to find the solution online. Though I found some solutions, they still have some problems, e.g., the annoying Untitled.txt
auto-creation when you start a new notebook from the dashboard.
So eventually I wrote my own solution:
import io
import os
import re
from nbconvert.exporters.script import ScriptExporter
from notebook.utils import to_api_path
def script_post_save(model, os_path, contents_manager, **kwargs):
"""Save a copy of notebook to the corresponding language source script.
For example, when you save a `foo.ipynb` file, a corresponding `foo.py`
python script will also be saved in the same directory.
However, existing config files I found online (including the one written in
the official documentation), will also create an `Untitile.txt` file when
you create a new notebook, even if you have not pressed the "save" button.
This is annoying because we usually will rename the notebook with a more
meaningful name later, and now we have to rename the generated script file,
too!
Therefore we make a change here to filter out the newly created notebooks
by checking their names. For a notebook which has not been given a name,
i.e., its name is `Untitled.*`, the corresponding source script will not be
saved. Note that the behavior also applies even if you manually save an
"Untitled" notebook. The rationale is that we usually do not want to save
scripts with the useless "Untitled" names.
"""
# only process for notebooks
if model["type"] != "notebook":
return
script_exporter = ScriptExporter(parent=contents_manager)
base, __ = os.path.splitext(os_path)
# do nothing if the notebook name ends with `Untitled[0-9]*`
regex = re.compile(r"Untitled[0-9]*$")
if regex.search(base):
return
script, resources = script_exporter.from_filename(os_path)
script_fname = base + resources.get('output_extension', '.txt')
log = contents_manager.log
log.info("Saving script at /%s",
to_api_path(script_fname, contents_manager.root_dir))
with io.open(script_fname, "w", encoding="utf-8") as f:
f.write(script)
c.FileContentsManager.post_save_hook = script_post_save
To use this script, you can add it to ~/.jupyter/jupyter_notebook_config.py
:)
Note that you may need to restart the jupyter notebook / lab for it to work.
Because without the PDB files, it would be impossible to debug a "Release" build by anything other than address-level debugging. Optimizations really do a number on your code, making it very difficult to find the culprit if something goes wrong (say, an exception is thrown). Even setting breakpoints is extremely difficult, because lines of source code cannot be matched up one-to-one with (or even in the same order as) the generated assembly code. PDB files help you and the debugger out, making post-mortem debugging significantly easier.
You make the point that if your software is ready for release, you should have done all your debugging by then. While that's certainly true, there are a couple of important points to keep in mind:
You should also test and debug your application (before you release it) using the "Release" build. That's because turning optimizations on (they are disabled by default under the "Debug" configuration) can sometimes cause subtle bugs to appear that you wouldn't otherwise catch. When you're doing this debugging, you'll want the PDB symbols.
Customers frequently report edge cases and bugs that only crop up under "ideal" conditions. These are things that are almost impossible to reproduce in the lab because they rely on some whacky configuration of that user's machine. If they're particularly helpful customers, they'll report the exception that was thrown and provide you with a stack trace. Or they'll even let you borrow their machine to debug your software remotely. In either of those cases, you'll want the PDB files to assist you.
Profiling should always be done on "Release" builds with optimizations enabled. And once again, the PDB files come in handy, because they allow the assembly instructions being profiled to be mapped back to the source code that you actually wrote.
You can't go back and generate the PDB files after the compile.* If you don't create them during the build, you've lost your opportunity. It doesn't hurt anything to create them. If you don't want to distribute them, you can simply omit them from your binaries. But if you later decide you want them, you're out of luck. Better to always generate them and archive a copy, just in case you ever need them.
If you really want to turn them off, that's always an option. In your project's Properties window, set the "Debug Info" option to "none" for any configuration you want to change.
Do note, however, that the "Debug" and "Release" configurations do by default use different settings for emitting debug information. You will want to keep this setting. The "Debug Info" option is set to "full" for a Debug build, which means that in addition to a PDB file, debugging symbol information is embedded into the assembly. You also get symbols that support cool features like edit-and-continue. In Release mode, the "pdb-only" option is selected, which, like it sounds, includes only the PDB file, without affecting the content of the assembly. So it's not quite as simple as the mere presence or absence of PDB files in your /bin
directory. But assuming you use the "pdb-only" option, the PDB file's presence will in no way affect the run-time performance of your code.
* As Marc Sherman points out in a comment, as long as your source code has not changed (or you can retrieve the original code from a version-control system), you can rebuild it and generate a matching PDB file. At least, usually. This works well most of the time, but the compiler is not guaranteed to generate identical binaries each time you compile the same code, so there may be subtle differences. Worse, if you have made any upgrades to your toolchain in the meantime (like applying a service pack for Visual Studio), the PDBs are even less likely to match. To guarantee the reliable generation of ex postfacto PDB files, you would need to archive not only the source code in your version-control system, but also the binaries for your entire build toolchain to ensure that you could precisely recreate the configuration of your build environment. It goes without saying that it is much easier to simply create and archive the PDB files.

From about section of Reverse IP Domain Check tool on yougetsignal:
A reverse IP domain check takes a domain name or IP address pointing to a web server and searches for other sites known to be hosted on that same web server. Data is gathered from search engine results, which are not guaranteed to be complete.
I'm not able to understand the flow of execution of the program, And when ob1 is created then the constructor is called where t.start() is written but still run() method is not executed rather main() method continues execution. So why is this happening?
This depends on Thread Scheduler as main shares the same priority order. Calling start() doesn't mean run() will be called immediately, it depends on thread scheduler when it chooses to run your thread.
join() method is used to wait until the thread on which it is called does not terminates, but here in output we see alternate outputs of the thread why??
This is because of the Thread.sleep(1000) in your code. Remove that line and you will see ob1 finishes before ob2 which in turn finishes before ob3 (as expected with join()). Having said that it all depends on when ob1 ob2 and ob3 started. Calling sleep will pause thread execution for >= 1 second (in your code), giving scheduler a chance to call other threads waiting (same priority).

Interesting info about MSCorlib:
.NET 1.1
assembly will reference the 1.1 mscorlib
but will use
the 2.0 mscorlib at runtime (due to hard-coded version redirects in
theruntime itself)MSCorlib 2.0
alone is in GAC whereas 1.x version live inside framework folderYou can select a code snippet and use right click menu to choose the action "Execute Selection in console".
Html.DisplayFor()
will render the DisplayTemplate that matches the property's type.
If it can't find any, I suppose it invokes .ToString()
.
If you don't know about display templates, they're partial views that can be put in a DisplayTemplates
folder inside the view folder associated to a controller.
Example:
If you create a view named String.cshtml
inside the DisplayTemplates
folder of your views folder (e.g Home
, or Shared
) with the following code:
@model string
@if (string.IsNullOrEmpty(Model)) {
<strong>Null string</strong>
}
else {
@Model
}
Then @Html.DisplayFor(model => model.Title)
(assuming that Title
is a string) will use the template and display <strong>Null string</strong>
if the string is null, or empty.
Its function depends on the builders that you have in your project (they can choose to interpret clean command however they like) and whether you have auto-build turned on. If auto-build is on, invoking clean is equivalent of a clean build. First artifacts are removed, then a full build is invoked. If auto-build is off, clean will remove the artifacts and stop. You can then invoke build manually later.

UPDATE:
To append Token to each request you can create one Interceptor as below.
import { Injectable } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';
@Injectable()
export class AuthInterceptor implements HttpInterceptor {
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
const token = window.localStorage.getItem('tokenKey'); // you probably want to store it in localStorage or something
if (!token) {
return next.handle(req);
}
const req1 = req.clone({
headers: req.headers.set('Authorization', `${token}`),
});
return next.handle(req1);
}
}
On my development machine I have three different versions of Oracle client software. I manage the tnsnames.ora
file in one of them. In the other two, I have entered in the tnsnames.ora
file:
ifile=path_to_tnsnames.ora_file/tnsnames.ora
This way, if for some reason the wrong tnsnames.ora
file is used by a client, it will always end up at the up-to-date version.
