For an automatic letterbox/pillarbox in a fixed-size rectangle, use the object-fit
CSS property. That is usually what I want, and it avoids using code to figure out which is the dominant dimension or — what I used to do — embedding an <SVG>
element with an <image>
child to wrap the content with its nice preserveAspectRatio
options.

This is an old post and I read through the answers. Still, I found it a bit too painful to output multi-line large text fields unaltered from SSMS. I ended up writing a small C# program for my needs, but got to thinking it could probably be done using the command line. Turns out, it is fairly easy to do so with PowerShell.
Start by installing the SqlServer
module from an administrative PowerShell.
Install-Module -Name SqlServer
Use Invoke-Sqlcmd
to run your query:
$Rows = Invoke-Sqlcmd -Query "select BigColumn from SomeTable where Id = 123" `
-As DataRows -MaxCharLength 1000000 -ConnectionString $ConnectionString
This will return an array of rows that you can output to the console as follows:
$Rows[0].BigColumn
Or output to a file as follows:
$Rows[0].BigColumn | Out-File -FilePath .\output.txt -Encoding UTF8
The result is a beautiful un-truncated text written to a file for viewing/editing. I am sure there is a similar command to save back the text to SQL Server, although that seems like a different question.
EDIT: It turns out that there was an answer by @dvlsc that described this approach as a secondary solution. I think because it was listed as a secondary answer, is the reason I missed it in the first place. I am going to leave my answer which focuses on the PowerShell approach, but wanted to at least give credit where it was due.
What about this:
from operator import itemgetter
itemgetter(0,2,3)(myList)
('foo', 'baz', 'quux')
Java 1.7 makes our lives much easier thanks to the try-with-resources statement.
try (Connection connection = dataSource.getConnection();
Statement statement = connection.createStatement()) {
try (ResultSet resultSet = statement.executeQuery("some query")) {
// Do stuff with the result set.
}
try (ResultSet resultSet = statement.executeQuery("some query")) {
// Do more stuff with the second result set.
}
}
This syntax is quite brief and elegant. And connection
will indeed be closed even when the statement
couldn't be created.
Yeah first method will work on any element called from elsewhere since it will always take the target element irrespective of id.

Asymptotic notation is something you can understand as: how do functions compare when zooming out? (A good way to test this is simply to use a tool like Desmos and play with your mouse wheel). In particular:
f(n) ? o(n)
means: at some point, the more you zoom out, the more f(n)
will be dominated by n
(it will progressively diverge from it).g(n) ? T(n)
means: at some point, zooming out will not change how g(n)
compare to n
(if we remove ticks from the axis you couldn't tell the zoom level).Finally h(n) ? O(n)
means that function h
can be in either of these two categories. It can either look a lot like n
or it could be smaller and smaller than n
when n
increases. Basically, both f(n)
and g(n)
are also in O(n)
.
In computer science, people will usually prove that a given algorithm admits both an upper O
and a lower bound . When both bounds meet that means that we found an asymptotically optimal algorithm to solve that particular problem.
For example, if we prove that the complexity of an algorithm is both in O(n)
and (n)
it implies that its complexity is in T(n)
. That's the definition of T
and it more or less translates to "asymptotically equal". Which also means that no algorithm can solve the given problem in o(n)
. Again, roughly saying "this problem can't be solved in less than n
steps".
An upper bound of O(n)
simply means that even in the worse case, the algorithm will terminate in at most n
steps (ignoring all constant factors, both multiplicative and additive). A lower bound of (n)
means on the opposite that we built some examples where the problem solved by this algorithm couldn't be solved in less than n
steps (again ignoring multiplicative and additive constants). The number of steps is at most n
and at least n
so this problem complexity is "exactly n
". Instead of saying "ignoring constant multiplicative/additive factor" every time we just write T(n)
for short.
For easy understand can see my figure.
Rebase will change commit hash, so that if you want to avoid much of conflict, just use rebase when that branch is done/complete as stable.
You should flatten using this code ( taken from http://kogs-www.informatik.uni-hamburg.de/~meine/python_tricks ), the code is untested, but I'm pretty sure it works:
def flatten(x):
"""flatten(sequence) -> list
Returns a single, flat list which contains all elements retrieved
from the sequence and all recursively contained sub-sequences
(iterables).
Examples:
>>> [1, 2, [3,4], (5,6)]
[1, 2, [3, 4], (5, 6)]
>>> flatten([[[1,2,3], (42,None)], [4,5], [6], 7, MyVector(8,9,10)])
[1, 2, 3, 42, None, 4, 5, 6, 7, 8, 9, 10]"""
result = []
for el in x:
#if isinstance(el, (list, tuple)):
if hasattr(el, "__iter__") and not isinstance(el, basestring):
result.extend(flatten(el))
else:
result.append(el)
return result
After you had flattened the list, you perform the intersection in the usual way:
c1 = [1, 6, 7, 10, 13, 28, 32, 41, 58, 63]
c2 = [[13, 17, 18, 21, 32], [7, 11, 13, 14, 28], [1, 5, 6, 8, 15, 16]]
def intersect(a, b):
return list(set(a) & set(b))
print intersect(flatten(c1), flatten(c2))
You are using the --noImplicitAny
and TypeScript doesn't know about the type of the Users
object. In this case, you need to explicitly define the user
type.
Change this line:
let user = Users.find(user => user.id === query);
to this:
let user = Users.find((user: any) => user.id === query);
// use "any" or some other interface to type this argument
Or define the type of your Users
object:
//...
interface User {
id: number;
name: string;
aliases: string[];
occupation: string;
gender: string;
height: {ft: number; in: number;}
hair: string;
eyes: string;
powers: string[]
}
//...
const Users = <User[]>require('../data');
//...
As vim's own help on set background
says, "Setting this option does not change the background color, it tells Vim what the background color looks like. For changing the background color, see |:hi-normal|."
For example
:highlight Normal ctermfg=grey ctermbg=darkblue
will write in white on blue on your color terminal.
Indexing in python starting from 0. You wrote [1:] this would not return you a first char in any case - this will return you a rest(except first char) of string.
If you have the following structure:
mylist = ['base', 'sample', 'test']
And want to get fist char for the first one string(item):
myList[0][0]
>>> b
If all first chars:
[x[0] for x in myList]
>>> ['b', 's', 't']
If you have a text:
text = 'base sample test'
text.split()[0][0]
>>> b
I meant in the template()
call..
You just need to pass the results as an object. So instead of calling
var html = template(data);
do
var html = template({apidata: data});
and use {{#each apidata}}
in your template code
demo at http://jsfiddle.net/KPCh4/4/
(removed some leftover if
code that crashed)
The default credentials are:
login: admin
password: admin
But if you use EAP these credentials are turned off by default and there is no active user (security reasons :)). If you want to turn on these users, you have to edit the following file in your current profile: ./deploy/management/console-mgr.sar/web-console.war/WEB-INF/classes/web-console-users.properties
. It should be enough to remove the #
sign from the line with the user.
If you want to create a new user, don't forget to set up the correct groups in web-console-roles.properties
file.
You can easily find information where these information are stored: just open the ./conf/login-config.xml
file and find the proper security domain definition. In the case of the Web Console application, it will be web-console
policy.
Also if you want to have access to JMX, you have unlock JMX Console. Just check the following files in the conf/props/
directory (in your profile): jmx-console-users.properties
and jmx-console-roles.properties
.

As always with these questions, the JLS holds the answer. In this case §15.26.2 Compound Assignment Operators. An extract:
A compound assignment expression of the form
E1 op= E2
is equivalent toE1 = (T)((E1) op (E2))
, whereT
is the type ofE1
, except thatE1
is evaluated only once.
An example cited from §15.26.2
[...] the following code is correct:
short x = 3; x += 4.6;
and results in x having the value 7 because it is equivalent to:
short x = 3; x = (short)(x + 4.6);
In other words, your assumption is correct.

Latest versions of Excel has a new tool called Slicers. Using slicers in VBA is actually more reliable that .CurrentPage (there have been reports of bugs while looping through numerous filter options). Here is a simple example of how you can select a slicer item (remember to deselect all the non-relevant slicer values):
Sub Step_Thru_SlicerItems2()
Dim slItem As SlicerItem
Dim i As Long
Dim searchName as string
Application.ScreenUpdating = False
searchName="Value1"
For Each slItem In .VisibleSlicerItems
If slItem.Name <> .SlicerItems(1).Name Then _
slItem.Selected = False
Else
slItem.Selected = True
End if
Next slItem
End Sub

We must define the behavior configuration to REST endpoint
<endpointBehaviors>
<behavior name="restfulBehavior">
<webHttp defaultOutgoingResponseFormat="Json" defaultBodyStyle="Wrapped" automaticFormatSelectionEnabled="False" />
</behavior>
</endpointBehaviors>
and also to a service
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
After the behaviors, next step is the bindings. For example basicHttpBinding to SOAP endpoint and webHttpBinding to REST.
<bindings>
<basicHttpBinding>
<binding name="soapService" />
</basicHttpBinding>
<webHttpBinding>
<binding name="jsonp" crossDomainScriptAccessEnabled="true" />
</webHttpBinding>
</bindings>
Finally we must define the 2 endpoint in the service definition. Attention for the address="" of endpoint, where to REST service is not necessary nothing.
<services>
<service name="ComposerWcf.ComposerService">
<endpoint address="" behaviorConfiguration="restfulBehavior" binding="webHttpBinding" bindingConfiguration="jsonp" name="jsonService" contract="ComposerWcf.Interface.IComposerService" />
<endpoint address="soap" binding="basicHttpBinding" name="soapService" contract="ComposerWcf.Interface.IComposerService" />
<endpoint address="mex" binding="mexHttpBinding" name="metadata" contract="IMetadataExchange" />
</service>
</services>
In Interface of the service we define the operation with its attributes.
namespace ComposerWcf.Interface
{
[ServiceContract]
public interface IComposerService
{
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "/autenticationInfo/{app_id}/{access_token}", ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
Task<UserCacheComplexType_RootObject> autenticationInfo(string app_id, string access_token);
}
}
Joining all parties, this will be our WCF system.serviceModel definition.
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="restfulBehavior">
<webHttp defaultOutgoingResponseFormat="Json" defaultBodyStyle="Wrapped" automaticFormatSelectionEnabled="False" />
</behavior>
</endpointBehaviors>

If the command that you are trying to execute fails, it would write the output onto the error stream and would then be printed out to the console.
To avoid it, you must redirect the error stream:
result=$(ls -l something_that_does_not_exist 2>&1)
I am using Swift from Google Colab. Here's how to check it in Colab.

As @David Heffeman indicates the recommendation is to use .yaml
when possible, and the recommendation has been that way since September 2006.
That some projects use .yml
is mostly because of ignorance of the implementers/documenters: they wanted to use YAML because of readability, or some other feature not available in other formats, were not familiar with the recommendation and and just implemented what worked, maybe after looking at some other project/library (without questioning whether what was done is correct).
The best way to approach this is to be rigorous when creating new files (i.e. use .yaml
) and be permissive when accepting input (i.e. allow .yml
when you encounter it), possible automatically upgrading/correcting these errors when possible.
The other recommendation I have is to document the argument(s) why you have to use .yml
, when you think you have to. That way you don't look like an ignoramus, and give others the opportunity to understand your reasoning. Of course "everybody else is doing it" and "On Google .yml
has more pages than .yaml
" are not arguments, they are just statistics about the popularity of project(s) that have it wrong or right (with regards to the extension of YAML files). You can try to prove that some projects are popular, just because they use a .yml
extension instead of the correct .yaml
, but I think you will be hard pressed to do so.
Some projects realize (too late) that they use the incorrect extension (e.g. originally docker-compose
used .yml
, but in later versions started to use .yaml
, although they still support .yml
). Others still seem ignorant about the correct extension, like AppVeyor early 2019, but allow you to specify the configuration file for a project, including extension. This allows you to get the configuration file out of your face as well as giving it the proper extension: I use .appveyor.yaml
instead of appveyor.yml
for building the windows wheels of my YAML parser for Python).
On the other hand:
The Yaml (sic!) component of Symfony2 implements a selected subset of features defined in the YAML 1.2 version specification.
So it seems fitting that they also use a subset of the recommended extension.
As you add more modules to Android, there is an incredible demand placed on the Android build system, and the default memory settings will not work. To avoid OutOfMemory
errors during Android builds, you should uncomment the alternate Gradle memory setting present in /android/gradle.properties
:
# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx10248m -XX:MaxPermSize=256m
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
if all your dates are the same width, you can put the dates in a vector and use substring
Date
a <- c("01/01/2009", "01/01/2010" , "01/01/2011")
substring(a,7,10) #This takes string and only keeps the characters beginning in position 7 to position 10
output
[1] "2009" "2010" "2011"
To increase the height of TextField Widget just make use of the maxLines: properties that comes with the widget. For Example: TextField( maxLines: 5 ) // it will increase the height and width of the Textfield.
Try
request.getSession().setAttribute("SUBFAMILY", subFam);
request.getSession().getAttribute("SUBFAMILY");
I often use row_number() as a quick way to discard duplicate records from my select statements. Just add a where clause. Something like...
select a,b,rn
from (select a, b, row_number() over (partition by a,b order by a,b) as rn
from table)
where rn=1;
Most answers here are correct but taken a bit out of context, so I will provide a full-fledged answer which works for Asp.Net Core 3.1. For completeness' sake:
[Route("health")]
[ApiController]
public class HealthController : Controller
{
[HttpGet("some_health_url")]
public ActionResult SomeHealthMethod() {}
}
[Route("v2")]
[ApiController]
public class V2Controller : Controller
{
[HttpGet("some_url")]
public ActionResult SomeV2Method()
{
return RedirectToAction("SomeHealthMethod", "Health"); // omit "Controller"
}
}
If you try to use any of the url-specific strings, e.g. "some_health_url"
, it will not work!
You can find where the my.cnf
file has been provided by the specific package, e.g.
brew list mysql # or: mariadb
In addition to verify if that file is read, you can run:
sudo fs_usage | grep my.cnf
which will show you filesystem activity in real-time related to that file.
Yet another approach - just set a flag on an element signaling which type of event should be handled:
function setRangeValueChangeHandler(rangeElement, handler) {
rangeElement.oninput = (event) => {
handler(event);
// Save flag that we are using onInput in current browser
event.target.onInputHasBeenCalled = true;
};
rangeElement.onchange = (event) => {
// Call only if we are not using onInput in current browser
if (!event.target.onInputHasBeenCalled) {
handler(event);
}
};
}
Let's get pedantic, because there are differences that can actually affect your code's behavior. Much of the following is taken from comments made to an "Old New Thing" article.
Sometimes the memory returned by the new operator will be initialized, and sometimes it won't depending on whether the type you're newing up is a POD (plain old data), or if it's a class that contains POD members and is using a compiler-generated default constructor.
Assume:
struct A { int m; }; // POD
struct B { ~B(); int m; }; // non-POD, compiler generated default ctor
struct C { C() : m() {}; ~C(); int m; }; // non-POD, default-initialising m
In a C++98 compiler, the following should occur:
new A
- indeterminate valuenew A()
- zero-initialize
new B
- default construct (B::m is uninitialized)
new B()
- default construct (B::m is uninitialized)
new C
- default construct (C::m is zero-initialized)
new C()
- default construct (C::m is zero-initialized)In a C++03 conformant compiler, things should work like so:
new A
- indeterminate valuenew A()
- value-initialize A, which is zero-initialization since it's a POD.
new B
- default-initializes (leaves B::m uninitialized)
new B()
- value-initializes B which zero-initializes all fields since its default ctor is compiler generated as opposed to user-defined.
new C
- default-initializes C, which calls the default ctor.
new C()
- value-initializes C, which calls the default ctor.So in all versions of C++ there's a difference between new A
and new A()
because A is a POD.
And there's a difference in behavior between C++98 and C++03 for the case new B()
.
This is one of the dusty corners of C++ that can drive you crazy. When constructing an object, sometimes you want/need the parens, sometimes you absolutely cannot have them, and sometimes it doesn't matter.
try this ( stringWithFormat has to start with lowercase)
[NSString stringWithFormat:@"%@\n%@",string1,string2];
Equals comparison:
((f1 IS NULL AND f2 IS NULL) OR (f1 IS NOT NULL AND f2 IS NOT NULL AND f1 = f2))
Not Equal To comparison: Just negate the Equals comparison above.
NOT ((f1 IS NULL AND f2 IS NULL) OR (f1 IS NOT NULL AND f2 IS NOT NULL AND f1 = f2))
Is it verbose? Yes, it is. However it's efficient since it doesn't call any function. The idea is to use short circuit in predicates to make sure the equal operator (=) is used only with non-null values, otherwise null would propagate up in the expression tree.
Solution is very simple
Just put following line into your style named as AppTheme
<item name="colorControlNormal">@color/white</item>
Now your whole xml code will look like shown below (default style).
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#0F0F0F</item>
<item name="android:statusBarColor">#EEEEF0</item>
<item name="android:windowLightStatusBar">true</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="android:windowActivityTransitions">true</item>
<item name="colorControlNormal">@color/white</item>
</style>
The reason why your X-axis plots frequencies only till 500 Hz is your command statement 'f = Fs/2*linspace(0,1,NFFT/2+1);'. Your Fs is 1000. So when you divide it by 2 & then multiply by values ranging from 0 to 1, it returns a vector of length NFFT/2+1. This vector consists of equally spaced frequency values, ranging from 0 to Fs/2 (i.e. 500 Hz). Since you plot using 'plot(f,2*abs(Y(1:NFFT/2+1)))' command, your X-axis limit is 500 Hz.
The number of parameters is 7850 because with every hidden unit you have 784 input weights and one weight of connection with bias. This means that every hidden unit gives you 785 parameters. You have 10 units so it sums up to 7850.
The role of this additional bias term is really important. It significantly increases the capacity of your model. You can read details e.g. here Role of Bias in Neural Networks.
A simple possibility (if you'd rather avoid REs) is
' '.join(mystring.split())
The split and join perform the task you're explicitly asking about -- plus, they also do the extra one that you don't talk about but is seen in your example, removing trailing spaces;-).
With the new ValueTuple
from C# 7 (VS 2017 and above), there is a new solution:
List<(int,string)> mylist= new List<(int,string)>();
Which creates a list of ValueTuple type. If you're targeting .Net Framework 4.7+ or .Net Core, it's native, otherwise you have to get the ValueTuple package from nuget.
It's a struct opposing to Tuple
, which is a class. It also has the advantage over the Tuple
class that you could create a named tuple, like this:
var mylist = new List<(int myInt, string myString)>();
That way you can access like mylist[0].myInt
and mylist[0].myString
Try something like:
WHERE (column LIKE '%this%' OR column LIKE '%that%') AND something = else
If you're using mariadb, you have to modify the mariadb.cnf file located in /etc/mysql/conf.d/.
I supposed the stuff is the same for any other my-sql based solutions.
std
namespace (where features of the C++ Standard Library, such as string
or vector
, are declared).After you write this instruction, if the compiler sees string
it will know that you may be referring to std::string
, and if it sees vector
, it will know that you may be referring to std::vector
. (Provided that you have included in your compilation unit the header files where they are defined, of course.)
If you don't write it, when the compiler sees string
or vector
it will not know what you are refering to. You will need to explicitly tell it std::string
or std::vector
, and if you don't, you will get a compile error.
If you want to be able to have a SELECT without problems of the parent id having to be lower than child id, a function could be used. It supports also multiple children (as a tree should do) and the tree can have multiple heads. It also ensure to break if a loop exists in the data.
I wanted to use dynamic SQL to be able to pass the table/columns names, but functions in MySQL don't support this.

The answer has been copied from this tutorial I wrote at LearnOpenCV.com explaining various parameters of SimpleBlobDetector. You can find additional details about the parameters in the tutorial.
When you commit, tick the Optimize imports

I prefer using the Reformat code
option as well.
Normally, calling
var b = a.slice();
will copy the array a
into b
. However, we can't do
var a = arguments.slice();
because arguments
isn't a real array, and doesn't have slice
as a method. Array.prototype.slice
is the slice
function for arrays, and call
runs the function with this
set to arguments
.
# make a list out of text - ['h','e','l','l','o']
text = list('hello')
while text:
print text.pop()
:)
In python empty object are evaluated as false. The .pop() removes and returns the last item on a list. And that's why it prints on reverse !
But can be fixed by using:
text.pop( 0 )
There's a situation where the cell has white space, you can't see it, use
df['col'].replace(' ', np.nan, inplace=True)
to replace white space as NaN, then
df= df.dropna(subset=['col'])
(this was probably better as a comment, but got too long)
So, after reading this I was curious if pre-allocating was actually faster, because in theory it should be. However, this blog gave some tips advising against it http://www.html5rocks.com/en/tutorials/speed/v8/.
So still being unsure, I put it to the test. And as it turns out it seems to in fact be slower.
var time = Date.now();
var temp = [];
for(var i=0;i<100000;i++){
temp[i]=i;
}
console.log(Date.now()-time);
var time = Date.now();
var temp2 = new Array(100000);
for(var i=0;i<100000;i++){
temp2[i] = i;
}
console.log(Date.now()-time);

1) Poor understanding of how to properly interact between Java and the database.
2) Over parsing, improper or no reuse of SQL
3) Failing to use BIND variables
4) Implementing procedural logic in Java when SQL set logic in the database would have worked (better).
5) Failing to do any reasonable performance or scalability testing prior to going into production
6) Using Crystal Reports and failing to set the schema name properly in the reports
7) Implementing SQL with Cartesian products due to ignorance of the execution plan (did you even look at the EXPLAIN PLAN?)
In Angular2, this can help to get components name:
getName() {
let comp:any = this.constructor;
return comp.name;
}
comp:any is needed because TypeScript compiler will issue errors since Function initially does not have property name.
Use cell arrays. This has an advantage over 3D arrays in that it does not require a contiguous memory space to store all the matrices. In fact, each matrix can be stored in a different space in memory, which will save you from Out-of-Memory errors if your free memory is fragmented. Here is a sample function to create your matrices in a cell array:
function result = createArrays(nArrays, arraySize)
result = cell(1, nArrays);
for i = 1 : nArrays
result{i} = zeros(arraySize);
end
end
To use it:
myArray = createArrays(requiredNumberOfArrays, [500 800]);
And to access your elements:
myArray{1}(2,3) = 10;
If you can't know the number of matrices in advance, you could simply use MATLAB's dynamic indexing to make the array as large as you need. The performance overhead will be proportional to the size of the cell array, and is not affected by the size of the matrices themselves. For example:
myArray{1} = zeros(500, 800);
if twoRequired, myArray{2} = zeros(500, 800); end
To supplement @artfulrobot's answer, if you want to show changed files between two branches:
git diff --name-status mybranch..myotherbranch
Be careful on precedence. If you place the newer branch first then it would show files as deleted rather than added.
Adding a grep
can refine things further:
git diff --name-status mybranch..myotherbranch | grep "A\t"
That will then show only files added in myotherbranch
.
For checking if a string contains whitespace use a Matcher
and call it's find method.
Pattern pattern = Pattern.compile("\\s");
Matcher matcher = pattern.matcher(s);
boolean found = matcher.find();
If you want to check if it only consists of whitespace then you can use String.matches
:
boolean isWhitespace = s.matches("^\\s*$");
You can't put <div>
inside <a>
- it's not valid (X)HTML.
Even though you style a span with display: block you still can't put block-level elements inside it: the (X)HTML still has to obey the (X)HTML DTD (whichever one you use), no matter how the CSS alters things.
The browser will probably display it as you want, but that doesn't make it right.
JAVA_HOME = C:\Program Files\Java\jdk(JDK version number)
Example: C:\Program Files\Java\jdk-10
And then restart you command prompt it works.
Your CarBootSaleList
class is not a list. It is a class that contain a list.
You have three options:
Make your CarBootSaleList
object implement IEnumerable
or
make your CarBootSaleList inherit from List<CarBootSale>
or
if you are lazy this could almost do the same thing without extra coding
List<List<CarBootSale>>
Adding java.util.list
will resolve your problem because List interface which you are trying to use is part of java.util.list
package.
You can still use the ExcelFile class (and the sheet_names
attribute):
xl = pd.ExcelFile('foo.xls')
xl.sheet_names # see all sheet names
xl.parse(sheet_name) # read a specific sheet to DataFrame
see docs for parse for more options...
DLL Export Viewer by NirSoft can be used to display exported functions in a DLL.
This utility displays the list of all exported functions and their virtual memory addresses for the specified DLL files. You can easily copy the memory address of the desired function, paste it into your debugger, and set a breakpoint for this memory address. When this function is called, the debugger will stop in the beginning of this function.
Both foo()
and bar()
may generate warnings in some IDEs. For example, IntelliJ IDEA will generate a Allocation of zero-length array
warning.
An alternative approach is to use Apache Commons Lang 3 ArrayUtils.toArray()
function with empty arguments:
public File[] bazz() {
return ArrayUtils.toArray();
}
This approach is both performance and IDE friendly, yet requires a 3rd party dependency. However, if you already have commons-lang3 in your classpath, you could even use statically-defined empty arrays for primitive types:
public String[] bazz() {
return ArrayUtils.EMPTY_STRING_ARRAY;
}
Using pipe:
cat en-tl.100.en | head -10
So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]
MySQL uses CONCAT() to concatenate strings
SELECT * FROM tableOne
LEFT JOIN tableTwo
ON tableTwo.query = CONCAT('category_id=', tableOne.category_id)
Variables declared inside a function are local to that function. For instance:
foo <- function() {
bar <- 1
}
foo()
bar
gives the following error: Error: object 'bar' not found
.
If you want to make bar
a global variable, you should do:
foo <- function() {
bar <<- 1
}
foo()
bar
In this case bar
is accessible from outside the function.
However, unlike C, C++ or many other languages, brackets do not determine the scope of variables. For instance, in the following code snippet:
if (x > 10) {
y <- 0
}
else {
y <- 1
}
y
remains accessible after the if-else
statement.
As you well say, you can also create nested environments. You can have a look at these two links for understanding how to use them:
Here you have a small example:
test.env <- new.env()
assign('var', 100, envir=test.env)
# or simply
test.env$var <- 100
get('var') # var cannot be found since it is not defined in this environment
get('var', envir=test.env) # now it can be found
I don't think what your asking is possible.
Basically, adding a class is the only way to accomplish this that I am aware of.
You can do like
HTML in PHP :
<?php
echo "<table>";
echo "<tr>";
echo "<td>Name</td>";
echo "<td>".$name."</td>";
echo "</tr>";
echo "</table>";
?>
Or You can write like.
PHP in HTML :
<?php /*Do some PHP calculation or something*/ ?>
<table>
<tr>
<td>Name</td>
<td><?php echo $name;?></td>
</tr>
</table>
<?php /*Do some PHP calculation or something*/ ?>
Means:
You can open a PHP tag with <?php
, now add your PHP code, then close the tag with ?>
and then write your html code. When needed to add more PHP, just open another PHP tag with <?php
.

$
is short-hand for String.Format
and is used with string interpolations, which is a new feature of C# 6. As used in your case, it does nothing, just as string.Format()
would do nothing.
It is comes into its own when used to build strings with reference to other values. What previously had to be written as:
var anInt = 1;
var aBool = true;
var aString = "3";
var formated = string.Format("{0},{1},{2}", anInt, aBool, aString);
Now becomes:
var anInt = 1;
var aBool = true;
var aString = "3";
var formated = $"{anInt},{aBool},{aString}";
There's also an alternative - less well known - form of string interpolation using $@
(the order of the two symbols is important). It allows the features of a @""
string to be mixed with $""
to support string interpolations without the need for \\
throughout your string. So the following two lines:
var someDir = "a";
Console.WriteLine($@"c:\{someDir}\b\c");
will output:
c:\a\b\c
Simple Answer Cross Check :
You might be defined Same Activity multiple times in the manifest.xml file.
OR
Activity or service or receiver you have defined in the manifest.xml file which is not in your project structure.
mvn clean install -U
-U
means force update of dependencies.
Also, if you want to import the project into eclipse, I first run:
mvn eclipse:eclipse
then run
mvn eclipse:clean
Seems to work for me, but that's just my pennies worth.
If you don't use ngRoute module, i.e. you don't have $viewContentLoaded event.
You can use another directive method:
angular.module('someModule')
.directive('someDirective', someDirective);
someDirective.$inject = ['$rootScope', '$timeout']; //Inject services
function someDirective($rootScope, $timeout){
return {
restrict: "A",
priority: Number.MIN_SAFE_INTEGER, //Lowest priority
link : function(scope, element, attr){
$timeout(
function(){
$rootScope.$emit("Some:event");
}
);
}
};
}
Accordingly to trusktr's answer it has lowest priority. Plus $timeout will cause Angular to run through an entire event loop before callback execution.
$rootScope used, because it allow to place directive in any scope of the application and notify only necessary listeners.
$rootScope.$emit will fire an event for all $rootScope.$on listeners only. The interesting part is that $rootScope.$broadcast will notify all $rootScope.$on as well as $scope.$on listeners Source
I had the same issue. The problem ended up being the path to the image file. Make sure the image path is relative to the location of the CSS file instead of the HTML.
subprocess.call
Automatically waits , you can also use:
p1.wait()
Fixing the seed is essential when we try to optimize a function that involves randomly generated numbers (e.g. in simulation based estimation). Loosely speaking, if we do not fix the seed, the variation due to drawing different random numbers will likely cause the optimization algorithm to fail.
Suppose that, for some reason, you want to estimate the standard deviation (sd) of a mean-zero normal distribution by simulation, given a sample. This can be achieved by running a numerical optimization around steps
The following functions do this, once without step 1., once including it:
# without fixing the seed
simllh <- function(sd, y, Ns){
simdist <- density(rnorm(Ns, mean = 0, sd = sd))
llh <- sapply(y, function(x){ simdist$y[which.min((x - simdist$x)^2)] })
return(-sum(log(llh)))
}
# same function with fixed seed
simllh.fix.seed <- function(sd,y,Ns){
set.seed(48)
simdist <- density(rnorm(Ns,mean=0,sd=sd))
llh <- sapply(y,function(x){simdist$y[which.min((x-simdist$x)^2)]})
return(-sum(log(llh)))
}
We can check the relative performance of the two functions in discovering the true parameter value with a short Monte Carlo study:
N <- 20; sd <- 2 # features of simulated data
est1 <- rep(NA,1000); est2 <- rep(NA,1000) # initialize the estimate stores
for (i in 1:1000) {
as.numeric(Sys.time())-> t; set.seed((t - floor(t)) * 1e8 -> seed) # set the seed to random seed
y <- rnorm(N, sd = sd) # generate the data
est1[i] <- optim(1, simllh, y = y, Ns = 1000, lower = 0.01)$par
est2[i] <- optim(1, simllh.fix.seed, y = y, Ns = 1000, lower = 0.01)$par
}
hist(est1)
hist(est2)
The resulting distributions of the parameter estimates are:
When we fix the seed, the numerical search ends up close to the true parameter value of 2 far more often.
should be done like that and not with delete operator:
localStorage.removeItem(key);
Use type="application/javascript"
In case of HTML5, the type attribute is obsolete, you may remove it. Note: that it defaults to "text/javascript" according to w3.org, so I would suggest to add the "application/javascript" instead of removing it.
http://www.w3.org/TR/html5/scripting-1.html#attr-script-type
The type attribute gives the language of the script or format of the data. If the attribute is present, its value must be a valid MIME type. The charset parameter must not be specified. The default, which is used if the attribute is absent, is "text/javascript".
Use "application/javascript", because "text/javascript" is obsolete:
RFC 4329: http://www.rfc-editor.org/rfc/rfc4329.txt
Deployed Scripting Media Types and Compatibility
Various unregistered media types have been used in an ad-hoc fashion to label and exchange programs written in ECMAScript and JavaScript. These include:
+-----------------------------------------------------+ | text/javascript | text/ecmascript | | text/javascript1.0 | text/javascript1.1 | | text/javascript1.2 | text/javascript1.3 | | text/javascript1.4 | text/javascript1.5 | | text/jscript | text/livescript | | text/x-javascript | text/x-ecmascript | | application/x-javascript | application/x-ecmascript | | application/javascript | application/ecmascript | +-----------------------------------------------------+
Use of the "text" top-level type for this kind of content is known to be problematic. This document thus defines text/javascript and text/
ecmascript but marks them as "obsolete". Use of experimental and
unregistered media types, as listed in part above, is discouraged.
The media types,* application/javascript * application/ecmascript
which are also defined in this document, are intended for common use and should be used instead.
This document defines equivalent processing requirements for the
types text/javascript, text/ecmascript, and application/javascript.
Use of and support for the media type application/ecmascript is
considerably less widespread than for other media types defined in
this document. Using that to its advantage, this document defines
stricter processing rules for this type to foster more interoperable
processing.
x-javascript is experimental, don't use it.
Annoyingly enough, if you want to use the default model binders, it looks like you will have to use numerical index values like a form POST.
See the following excerpt from this article http://msdn.microsoft.com/en-us/magazine/hh781022.aspx:
Though it’s somewhat counterintuitive, JSON requests have the same requirements—they, too, must adhere to the form post naming syntax. Take, for example, the JSON payload for the previous UnitPrice collection. The pure JSON array syntax for this data would be represented as:
[ { "Code": "USD", "Amount": 100.00 }, { "Code": "EUR", "Amount": 73.64 } ]
However, the default value providers and model binders require the data to be represented as a JSON form post:
{ "UnitPrice[0].Code": "USD", "UnitPrice[0].Amount": 100.00, "UnitPrice[1].Code": "EUR", "UnitPrice[1].Amount": 73.64 }
The complex object collection scenario is perhaps one of the most widely problematic scenarios that developers run into because the syntax isn’t necessarily evident to all developers. However, once you learn the relatively simple syntax for posting complex collections, these scenarios become much easier to deal with.
I found a slight alteration on what @jota3 suggested worked perfectly for me.
var intersections = array1.filter(e => array2.indexOf(e) !== -1);
Hope this helps!
Earlier it used to be android:capitalize="words"
, which is now deprecated. The recommended alternative is to use android:inputType="textCapWords"
Please note that this will only work if your device keyboard Auto Capitalize Setting enabled.
To do this programatically, use the following method:
setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_CAP_WORDS);
You could also simply tell your RestTemplate
to accept all media types:
@Bean
public RestTemplate restTemplate() {
final RestTemplate restTemplate = new RestTemplate();
List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
converter.setSupportedMediaTypes(Collections.singletonList(MediaType.ALL));
messageConverters.add(converter);
restTemplate.setMessageConverters(messageConverters);
return restTemplate;
}
For 2020.1.4 Ultimate edition, I had to do the following

You can try this:
/*iPad landscape oriented styles */
@media only screen and (device-width:768px)and (orientation:landscape){
.yourstyle{
}
}
/*iPad Portrait oriented styles */
@media only screen and (device-width:768px)and (orientation:portrait){
.yourstyle{
}
}
A tuple technically qualifies as a constant, as a tuple will raise an error if you try to change one of its values. If you want to declare a tuple with one value, then place a comma after its only value, like this:
my_tuple = (0 """Or any other value""",)
To check this variable's value, use something similar to this:
if my_tuple[0] == 0:
#Code goes here
If you attempt to change this value, an error will be raised.
This works in MAC for me
sed -i.bak -e 's/regex/xregex/g' input.txt sed -i.bak -e 's/qregex/\'$'\nregex/g' input.txt
Dono whether its perfect one...
This happens to me once: I uninstalled the IIS, and the port 80 still was used. Well the problem was that also I had the Report Service
of the Sql Server 2012
installed, so I stopped that service and the problems solves.
See Stop Or Uninstall IIS for running Wamp Server (Apache) on default port (:80) question for more details.
Hope this helps some body, as it help to me.
There is a batch file called resetroot.bat
located in the xammp folders 'C:\xampp\mysql' run this and it will delete the phpmyadmin
passwords. Then all you need to do is start the MySQL
service in xamp
and click the admin button.
make sure you add {} around Html.RenderPartial, as:
@{Html.RenderPartial("FullName", new { firstName = model.FirstName, lastName = model.LastName});}
not
@Html.RenderPartial("FullName", new { firstName = model.FirstName, lastName = model.LastName});
The application/x-www-form-urlencoded
Content-type header is not needed. Unless the request handler expects the parameters coming from request body. Try it out:
curl -X DELETE "http://localhost:5000/locations?id=3"
or
curl -X GET "http://localhost:5000/locations?id=3"
-Xmn : the size of the heap for the young generation Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor" .

You can also change the caracter set in your browser. Just for debug reasons.
These are all good answers, however many forget to close the cursor and database. If you don't close the cursor or database you may run in to memory leaks.
Additionally:
You can get an error when searching by String
that contains non alpha/numeric characters. For example: "1a5f9ea3-ec4b-406b-a567-e6927640db40
". Those dashes (-
) will cause an unrecognized token
error. You can overcome this by putting the string in an array. So make it a habit to query like this:
public boolean hasObject(String id) {
SQLiteDatabase db = getWritableDatabase();
String selectString = "SELECT * FROM " + _TABLE + " WHERE " + _ID + " =?";
// Add the String you are searching by here.
// Put it in an array to avoid an unrecognized token error
Cursor cursor = db.rawQuery(selectString, new String[] {id});
boolean hasObject = false;
if(cursor.moveToFirst()){
hasObject = true;
//region if you had multiple records to check for, use this region.
int count = 0;
while(cursor.moveToNext()){
count++;
}
//here, count is records found
Log.d(TAG, String.format("%d records found", count));
//endregion
}
cursor.close(); // Dont forget to close your cursor
db.close(); //AND your Database!
return hasObject;
}
The clue is to work with the dict's items (i.e. key-value pair tuples). Then by using the second element of the item as the max
key (as opposed to the dict
key) you can easily extract the highest value and its associated key.
mydict = {'A':4,'B':10,'C':0,'D':87}
>>> max(mydict.items(), key=lambda k: k[1])
('D', 87)
>>> min(mydict.items(), key=lambda k: k[1])
('C', 0)
Squashing the first and second commit would result in the first commit being rewritten. If you have more than one branch that is based off the first commit, you'd cut off that branch.
Consider the following example:
a---b---HEAD
\
\
'---d
Squashing a and b into a new commit "ab" would result in two distinct trees which in most cases is not desirable since git-merge and git-rebase will no longer work across the two branches.
ab---HEAD
a---d
If you really want this, it can be done. Have a look at git-filter-branch for a powerful (and dangerous) tool for history rewriting.
I specifically was looking for the XML representation for Android.Graphics.Color. I didn't find these, so here you are. More details are in the help document.
<?xml version="1.0" encoding="utf-8"?>

Of course, this is used like this:

This is the way how to intialize value to var variable
var _myVal = (dynamic)null;
How about using a Regex?
var result = Regex.Replace(input, "\r\n", String.Empty)
If you just want to remove the new line at the very end use this
var result = Regex.Replace(input, "\r\n$", String.Empty)
I believe that you are trying to connect to a something using SSL but that something is providing a certificate which is not verified by root certification authorities such as verisign.. In essence by default secure connections can only be established if the person trying to connect knows the counterparties keys or some other verndor such as verisign can step in and say that the public key being provided is indeed right..
ALL OS's trust a handful of certification authorities and smaller certificate issuers need to be certified by one of the large certifiers making a chain of certifiers if you get what I mean...
Anyways coming back to the point.. I had a similiar problem when programming a java applet and a java server ( Hopefully some day I will write a complete blogpost about how I got all the security to work :) )
In essence what I had to do was to extract the public keys from the server and store it in a keystore inside my applet and when I connected to the server I used this key store to create a trust factory and that trust factory to create the ssl connection. There are alterante procedures as well such as adding the key to the JVM's trusted host and modifying the default trust store on start up..
I did this around two months back and dont have source code on me right now.. use google and you should be able to solve this problem. If you cant message me back and I can provide you the relevent source code for the project .. Dont know if this solves your problem since you havent provided the code which causes these exceptions. Furthermore I was working wiht applets thought I cant see why it wont work on Serverlets...
P.S I cant get source code before the weekend since external SSH is disabled in my office :(
There is a commercial product with an interesting logo which lets you see all kind of traffic between server and client named charles.
Another open source tools include: Live HttpHeaders, Wireshark or Firebug.
Per Jquery docs
The .val() method is primarily used to get the values of form elements such as input, select and textarea. When called on an empty collection, it returns undefined.
In order to retrieve the value store in the text box with id txtEmail, you can use
$("#txtEmail").val()
Nice! Very slick.
I was disappointed that Excel doesn't let us paste to a merged cell and also pastes results containing a break into successive rows below the "target" cell though, as that meant it simply doesn't work for me. I tried a few tweaks (unmerge/remerge, etc.) but then Excel dropped anything below a break, so that was a dead end.
Ultimately, I came up with a routine that'll handle simple tags and not use the "native" Unicode converter that is causing the issue with merged fields. Hope others find this useful:

Note this doesn't care about tag nesting, instead only requiring a close tag for every open tag, and assuming the close tag nearest the opening tag applies to the opening tag. Properly nested tags will work fine, while improperly nested tags will not be rejected and may or may not work.

I realize this is an old question, but I use a much simpler way. Typically I just grab the list that I need, either by query or copying an existing list or whatever, then remove the duplicates. We will assume for this answer that your list is already in column C, row 4, as per the original question. This method works for whatever size list you have and you can select header yes or no.
Dim rng as range
Range("C4").Select
Set rng = Range(Selection, Selection.End(xlDown))
rng.RemoveDuplicates Columns:=1, Header:=xlYes
It's better to use $(window).scroll()
rather than $('#Eframe').on("mousewheel")
$('#Eframe').on("mousewheel")
will not trigger if people manually scroll using up and down arrows on the scroll bar or grabbing and dragging the scroll bar itself.
$(window).scroll(function(){
var scrollPos = $(document).scrollTop();
console.log(scrollPos);
});
If #Eframe
is an element with overflow:scroll
on it and you want it's scroll position. I think this should work (I haven't tested it though).
$('#Eframe').scroll(function(){
var scrollPos = $('#Eframe').scrollTop();
console.log(scrollPos);
});
In my own experience, even though theoretically many JetBrains products share the same functionalities, the new features that get introduced in some apps don't get immediately introduced in the others. In particular, IntelliJ IDEA has a new version once per year, while WebStorm and PHPStorm get 2 to 3 per year I think. Keep that in mind when choosing an IDE. :)
This Works for me.

If you want to update items with a Where
clause, using a .Where(...) will truncate your results if you do:
mylist = mylist.Where(n => n.Id == ID).Select(n => { n.Property = ""; return n; }).ToList();
You can do updates to specific item(s) in the list like so:
mylist = mylist.Select(n => { if (n.Id == ID) { n.Property = ""; } return n; }).ToList();
Always return item even if you don't make any changes. This way it will be kept in the list.
you can get the size of InputStream using getBytes(inputStream) of Utils.java check this following link
There is a neat way of doing this.
If it's an Unit Test you can do this:
@RunWith(MockitoJUnitRunner.class)
public class MyUnitTest {
@Mock
private MyFirstMock myFirstMock;
@Mock
private MySecondMock mySecondMock;
@Spy
private MySpiedClass mySpiedClass = new MySpiedClass();
// It's gonna inject the 2 mocks and the spied object per reflection to this object
// The java doc of @InjectMocks explains it really well how and when it does the injection
@InjectMocks
private MyClassToTest myClassToTest;
@Test
public void testSomething() {
}
}
EDIT: If it's an Integration test you can do this(not intended to be used that way with Spring. Just showcase that you can initialize mocks with diferent Runners):
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("aplicationContext.xml")
public class MyIntegrationTest {
@Mock
private MyFirstMock myFirstMock;
@Mock
private MySecondMock mySecondMock;
@Spy
private MySpiedClass mySpiedClass = new MySpiedClass();
// It's gonna inject the 2 mocks and the spied object per reflection to this object
// The java doc of @InjectMocks explains it really well how and when it does the injection
@InjectMocks
private MyClassToTest myClassToTest;
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
}
@Test
public void testSomething() {
}
}

I tried the following sequence of commands and was happy that I could solve it just using "tail" command [ with the options available on Mac ]. So, if you are on Mac, and want to use only "tail" to solve this problem, you can use this command :
cat file.txt | tail -r | tail -n +2 | tail -r
1> tail -r : simply reverses the order of lines in its input
2> tail -n +2 : this prints all the lines starting from the second line in its input
For Typescript users, the "atom-typescript" package adds a typescript aware symbols view, you can trigger it with Cmd+R, and it works great to jump to methods-
https://atom.io/packages/atom-typescript#alternative-to-symbols-view
Wildcard works for me also, but I'd like to give a side note for those using directory variables. Always use slash for folder tree (not backslash), otherwise it will fail:
BASEDIR = ../..
SRCDIR = $(BASEDIR)/src
INSTALLDIR = $(BASEDIR)/lib
MODULES = $(wildcard $(SRCDIR)/*.cpp)
OBJS = $(wildcard *.o)
You can also use the FontAwesome icon with the CSS3 pseudo selector as shown below.
Ensure to set the font-family to FontAwesome as shown below:
table.dataTable thead th.sorting:after {font-family: FontAwesome;}
To get the above working, you must do the following:
<head></head>
section of your app as shown below:
Here's the solution using jQuery:
$().ready(function () {
$(".formToValidate").validate();
$(".checkBox").each(function (item) {
$(this).rules("add", {
required: true,
minlength:3
});
});
});
For whatever reason, the Scanner class also issues this same exception if it encounters special characters it cannot read. Beyond using the hasNextLine()
method before each call to nextLine()
, make sure the correct encoding is passed to the Scanner
constructor, e.g.:
Scanner scanner = new Scanner(new FileInputStream(filePath), "UTF-8");
Both prior answers are definitely good solutions. If you're amenable to a library, I like moment.js - it does a lot more than just getting/formatting the date.
Both will works like a charm :),
JAVASCRIPT:
function CopyToClipboard(containerid) {
if (document.selection) {
var range = document.body.createTextRange();
range.moveToElementText(document.getElementById(containerid));
range.select().createTextRange();
document.execCommand("copy");
} else if (window.getSelection) {
var range = document.createRange();
range.selectNode(document.getElementById(containerid));
window.getSelection().addRange(range);
document.execCommand("copy");
alert("text copied")
}}
Also in html,
<button id="button1" onclick="CopyToClipboard('div1')">Click to copy</button>
<div id="div1" >Text To Copy </div>
<textarea placeholder="Press ctrl+v to Paste the copied text" rows="5" cols="20"></textarea>
You can do this by using a content provider. Each data item used in the application remains private to the application. If an application want to share data accross applications, there is only technique to achieve this, using a content provider, which provides interface to access that private data.
In the header file
header file
#ifndef SHAREFILE_INCLUDED
#define SHAREFILE_INCLUDED
#ifdef MAIN_FILE
int global;
#else
extern int global;
#endif
#endif
In the file with the file you want the global to live:
#define MAIN_FILE
#include "share.h"
In the other files that need the extern version:
#include "share.h"
You can use the beforeSend
callback to set additional parameters (The XMLHTTPRequest
object is passed to it as its only parameter).
Just so you know, this type of cross-domain request will not work in a normal site scenario and not with any other browser. I don't even know what security limitations FF 3.5 imposes as well, just so you don't beat your head against the wall for nothing:
$.ajax({
url: 'http://bar.other',
data: { whatever:'cool' },
type: 'GET',
beforeSend: function(xhr){
xhr.withCredentials = true;
}
});
One more thing to beware of, is that jQuery is setup to normalize browser differences. You may find that further limitations are imposed by the jQuery library that prohibit this type of functionality.
At university we were taught 'best practice' was to use != when working for employers, though all the operators above have the same functionality.
Two things to keep in mind Content-Type and the Encoding
1) What if the file is css
if (/.(css)$/.test(path)) {
res.writeHead(200, {'Content-Type': 'text/css'});
res.write(data, 'utf8');
}
2) What if the file is jpg/png
if (/.(jpg)$/.test(path)) {
res.writeHead(200, {'Content-Type': 'image/jpg'});
res.end(data,'Base64');
}
Above one is just a sample code to explain the answer and not the exact code pattern.
Add this code before the HttpsURLConnection
and it will be done. I got it.
private void trustEveryone() {
try {
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){
public boolean verify(String hostname, SSLSession session) {
return true;
}});
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, new X509TrustManager[]{new X509TrustManager(){
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException {}
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {}
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}}}, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(
context.getSocketFactory());
} catch (Exception e) { // should never happen
e.printStackTrace();
}
}
I hope this helps you.
EDIT: This answer is now outdated, see the updated version.
In my R package I have enhanced sample
so that it now behaves as expected also for data frames:
library(devtools); install_github('kimisc', 'krlmlr')
library(kimisc)
example(sample.data.frame)
smpl..> set.seed(42)
smpl..> sample(data.frame(a=c(1,2,3), b=c(4,5,6),
row.names=c('a', 'b', 'c')), 10, replace=TRUE)
a b
c 3 6
c.1 3 6
a 1 4
c.2 3 6
b 2 5
b.1 2 5
c.3 3 6
a.1 1 4
b.2 2 5
c.4 3 6
This is achieved by making sample
an S3 generic method and providing the necessary (trivial) functionality in a function. A call to setMethod
fixes everything. The original implementation still can be accessed through base::sample
.
Well if you know the order of your words.. you can use:
SELECT `name` FROM `table` WHERE `name` REGEXP 'Stylus.+2100'
Also you can use:
SELECT `name` FROM `table` WHERE `name` LIKE '%Stylus%' AND `name` LIKE '%2100%'
I solved this issue just by adding
import { AppRegistry } from "react-native";
import App from "./App";
import { name as appName } from "./app.json";
AppRegistry.registerComponent(appName, () => App);
to my index.js
make sure this exists in your index.js
The trick to make infinity's answer work without the flickering is to put the scroll-check on another div then the one you want to have fixed.
Derived from the code viixii.com uses I ended up using this:
function sticky_relocate() {
var window_top = $(window).scrollTop();
var div_top = $('#sticky-anchor').offset().top;
if (window_top > div_top)
$('#sticky-element').addClass('sticky');
else
$('#sticky-element').removeClass('sticky');
}
$(function() {
$(window).scroll(sticky_relocate);
sticky_relocate();
});
This way the function is only called once the sticky-anchor is reached and thus won't be removing and adding the '.sticky' class on every scroll event.
Now it adds the sticky class when the sticky-anchor reaches the top and removes it once the sticky-anchor return into view.
Just place an empty div with a class acting like an anchor just above the element you want to have fixed.
Like so:
<div id="sticky-anchor"></div>
<div id="sticky-element">Your sticky content</div>
All credit for the code goes to viixii.com
There's AppUpdater library. How to include:

robocopy also tends to print empty lines even if it does not do anything. I'm filtering empty lines away using command like this:
robocopy /NDL /NJH /NJS /NP /NS /NC %fromDir% %toDir% %filenames% | findstr /r /v "^$"
The rgba() function can accept a single hex color as well decimal RGB values. For example, this would work just fine:
@mixin background-opacity($color, $opacity: 0.3) {
background: $color; /* The Fallback */
background: rgba($color, $opacity);
}
element {
@include background-opacity(#333, 0.5);
}
If you ever need to break the hex color into RGB components, though, you can use the red(), green(), and blue() functions to do so:
$red: red($color);
$green: green($color);
$blue: blue($color);
background: rgb($red, $green, $blue); /* same as using "background: $color" */
you can use this for making a list Unique
ArrayList<String> listWithDuplicateValues = new ArrayList<>();
list.add("first");
list.add("first");
list.add("second");
ArrayList uniqueList = (ArrayList) listWithDuplicateValues.stream().distinct().collect(Collectors.toList());
I use Tkinter after() method, which doesn't "steal the game" (like the sched module that was presented earlier), i.e. it allows other things to run in parallel:
import Tkinter
def do_something1():
global n1
n1 += 1
if n1 == 6: # (Optional condition)
print "* do_something1() is done *"; return
# Do your stuff here
# ...
print "do_something1() "+str(n1)
tk.after(1000, do_something1)
def do_something2():
global n2
n2 += 1
if n2 == 6: # (Optional condition)
print "* do_something2() is done *"; return
# Do your stuff here
# ...
print "do_something2() "+str(n2)
tk.after(500, do_something2)
tk = Tkinter.Tk();
n1 = 0; n2 = 0
do_something1()
do_something2()
tk.mainloop()
do_something1()
and do_something2()
can run in parallel and in whatever interval speed. Here, the 2nd one will be executed twice as fast.Note also that I have used a simple counter as a condition to terminate either function. You can use whatever other contition you like or none if you what a function to run until the program terminates (e.g. a clock).

Sign-off is a requirement for getting patches into the Linux kernel and a few other projects, but most projects don't actually use it.
It was introduced in the wake of the SCO lawsuit, (and other accusations of copyright infringement from SCO, most of which they never actually took to court), as a Developers Certificate of Origin. It is used to say that you certify that you have created the patch in question, or that you certify that to the best of your knowledge, it was created under an appropriate open-source license, or that it has been provided to you by someone else under those terms. This can help establish a chain of people who take responsibility for the copyright status of the code in question, to help ensure that copyrighted code not released under an appropriate free software (open source) license is not included in the kernel.
There are many uses for the **null** value in the Boolean wrapper! :)
For example, you may have in a form a field named "newsletter" that indicate if the user want or doesn't want a newsletter from your site. If the user doesn't select a value in this field, you may want to implement a default behaviour to that situation (send? don't send?, question again?, etc) . Clearly, not set (or not selected or **null**), is not the same that true or false.
But, if "not set" doesn't apply to your model, don't change the boolean primitive ;)
Use a NavigableMap
implementation, like TreeMap
.
/* Setup */
NavigableMap<Integer, Optional<String>> messages = new TreeMap<>();
messages.put(Integer.MIN_VALUE, Optional.empty());
messages.put(1, Optional.of("testing case 1 to 5"));
messages.put(6, Optional.of("testing case 6 to 10"));
messages.put(11, Optional.empty());
/* Use */
messages.floorEntry(3).getValue().ifPresent(System.out::println);
Simplest is to class-ify all of the divs:
div.rounded {
background: #CFFEB6 url('tr.gif') no-repeat top right;
}
div.rounded div.br {
background: url('br.gif') no-repeat bottom right;
}
div.rounded div.br div.bl {
background: url('bl.gif') no-repeat bottom left;
}
div.rounded div.br div.bl div.inner {
padding: 10px;
}
.button {
border: 1px solid #999;
background:#eeeeee url('');
text-align:center;
}
.button:hover {
background-color:#c4e2f2;
}
And then use:
<div class='round'><div class='br'><div class='bl'><div class='inner'>
<div class='button'><a href='#'>Test</a></div>
</div></div></div></div>
chunks = [data[100*i:100*(i+1)] for i in range(len(data)/100 + 1)]
This is equivalent to the accepted answer. For example, shortening to batches of 10 for readability:
data = range(35)
print [data[x:x+10] for x in xrange(0, len(data), 10)]
print [data[10*i:10*(i+1)] for i in range(len(data)/10 + 1)]
Outputs:

How to customize different buttons in Android
The probable reason why you get this error is likely because you've added the /build folder to your .gitignore file or generally haven't checked it into Git.
So when you Git push Heroku master, the build folder you're referencing don't get pushed to Heroku. And that's why it shows this error.
That's the reason it works properly locally, but not when you deployed to Heroku.
You can use Date.UTC method to get the time stamp at the UTC timezone.
Usage:
var now = new Date;
var utc_timestamp = Date.UTC(now.getUTCFullYear(),now.getUTCMonth(), now.getUTCDate() ,
now.getUTCHours(), now.getUTCMinutes(), now.getUTCSeconds(), now.getUTCMilliseconds());

This thread seems to be missing an option available since Python 3.6: datetime.astimezone(tz=None)
can be used to get an aware datetime object representing local time (docs). This can then easily be converted to UTC.
from datetime import datetime, timezone
s = "2008-09-17 14:02:00"
# to datetime object:
dt = datetime.fromisoformat(s) # Python 3.7
# I'm on time zone Europe/Berlin; CEST/UTC+2 during summer 2008
dt = dt.astimezone()
print(dt)
# 2008-09-17 14:02:00+02:00
# ...and to UTC:
dtutc = dt.astimezone(timezone.utc)
print(dtutc)
# 2008-09-17 12:02:00+00:00
There is one caveat though, see astimezone(None) gives aware datetime, unaware of DST.

TL;DR
Error #1064 means that MySQL can't understand your command. To fix it:
Read the error message. It tells you exactly where in your command MySQL got confused.
Examine your command. If you use a programming language to create your command, use
echo
,console.log()
, or its equivalent to show the entire command so you can see it.Check the manual. By comparing against what MySQL expected at that point, the problem is often obvious.
Check for reserved words. If the error occurred on an object identifier, check that it isn't a reserved word (and, if it is, ensure that it's properly quoted).
Error messages may look like gobbledygook, but they're (often) incredibly informative and provide sufficient detail to pinpoint what went wrong. By understanding exactly what MySQL is telling you, you can arm yourself to fix any problem of this sort in the future.
As in many programs, MySQL errors are coded according to the type of problem that occurred. Error #1064 is a syntax error.
Whilst "syntax" is a word that many programmers only encounter in the context of computers, it is in fact borrowed from wider linguistics. It refers to sentence structure: i.e. the rules of grammar; or, in other words, the rules that define what constitutes a valid sentence within the language.
For example, the following English sentence contains a syntax error (because the indefinite article "a" must always precede a noun):
This sentence contains syntax error a.
Whenever one issues a command to a computer, one of the very first things that it must do is "parse" that command in order to make sense of it. A "syntax error" means that the parser is unable to understand what is being asked because it does not constitute a valid command within the language: in other words, the command violates the grammar of the programming language.
It's important to note that the computer must understand the command before it can do anything with it. Because there is a syntax error, MySQL has no idea what one is after and therefore gives up before it even looks at the database and therefore the schema or table contents are not relevant.
Obviously, one needs to determine how it is that the command violates MySQL's grammar. This may sound pretty impenetrable, but MySQL is trying really hard to help us here. All we need to do is…
MySQL not only tells us exactly where the parser encountered the syntax error, but also makes a suggestion for fixing it. For example, consider the following SQL command:
UPDATE my_table WHERE id=101 SET name='foo'
That command yields the following error message:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id=101 SET name='foo'' at line 1
MySQL is telling us that everything seemed fine up to the word WHERE
, but then a problem was encountered. In other words, it wasn't expecting to encounter WHERE
at that point.
Messages that say ...near '' at line...
simply mean that the end of command was encountered unexpectedly: that is, something else should appear before the command ends.
Programmers often create SQL commands using a programming language. For example a php program might have a (wrong) line like this:
$result = $mysqli->query("UPDATE " . $tablename ."SET name='foo' WHERE id=101");
If you write this this in two lines
$query = "UPDATE " . $tablename ."SET name='foo' WHERE id=101"
$result = $mysqli->query($query);
then you can add echo $query;
or var_dump($query)
to see that the query actually says
UPDATE userSET name='foo' WHERE id=101
Often you'll see your error immediately and be able to fix it.
MySQL is also recommending that we "check the manual that corresponds to our MySQL version for the right syntax to use". Let's do that.
I'm using MySQL v5.6, so I'll turn to that version's manual entry for an UPDATE
command. The very first thing on the page is the command's grammar (this is true for every command):
UPDATE [LOW_PRIORITY] [IGNORE] table_reference
SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
[WHERE where_condition]
[ORDER BY ...]
[LIMIT row_count]
The manual explains how to interpret this syntax under Typographical and Syntax Conventions, but for our purposes it's enough to recognise that: clauses contained within square brackets [
and ]
are optional; vertical bars |
indicate alternatives; and ellipses ...
denote either an omission for brevity, or that the preceding clause may be repeated.
We already know that the parser believed everything in our command was okay prior to the WHERE
keyword, or in other words up to and including the table reference. Looking at the grammar, we see that table_reference
must be followed by the SET
keyword: whereas in our command it was actually followed by the WHERE
keyword. This explains why the parser reports that a problem was encountered at that point.
Of course, this was a simple example. However, by following the two steps outlined above (i.e. observing exactly where in the command the parser found the grammar to be violated and comparing against the manual's description of what was expected at that point), virtually every syntax error can be readily identified.
I say "virtually all", because there's a small class of problems that aren't quite so easy to spot—and that is where the parser believes that the language element encountered means one thing whereas you intend it to mean another. Take the following example:
UPDATE my_table SET where='foo'
Again, the parser does not expect to encounter WHERE
at this point and so will raise a similar syntax error—but you hadn't intended for that where
to be an SQL keyword: you had intended for it to identify a column for updating! However, as documented under Schema Object Names:
If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it. (Exception: A reserved word that follows a period in a qualified name must be an identifier, so it need not be quoted.) Reserved words are listed at Section 9.3, “Keywords and Reserved Words”.
[ deletia ]The identifier quote character is the backtick (“
`
”):mysql> SELECT * FROM `select` WHERE `select`.id > 100;
If the
ANSI_QUOTES
SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks:mysql> CREATE TABLE "test" (col INT); ERROR 1064: You have an error in your SQL syntax... mysql> SET sql_mode='ANSI_QUOTES'; mysql> CREATE TABLE "test" (col INT); Query OK, 0 rows affected (0.00 sec)
strip
does nothing but, removes the the whitespace in your string. If you want to remove the extra whitepace from front and back of your string, you can use strip.
The example string which can illustrate that is this:
In [2]: x = "something \t like \t this"
In [4]: x.split('\t')
Out[4]: ['something ', ' like ', ' this']
See, even after splitting with \t
there is extra whitespace in first and second items which can be removed using strip in your code.
In Laravel 5.x you can use laravelcollective/html and the syntax:
{!! Html::image('img/logo.png') !!}
:last-child
only works when the element in question is the last child of the container, not the last of a specific type of element. For that, you want :last-of-type
As per @BoltClock's comment, this is only checking for the last article
element, not the last element with the class of .comment

If you want to read only one field value, I think, using the template reference variables is the easiest way
Template
<input #phone placeholder="phone number" />
<input type="button" value="Call" (click)="callPhone(phone.value)" />
**Component**
callPhone(phone): void
{
console.log(phone);
}
If you have a number of fields, using the reactive form one of the best ways.
Using .Equals is also a lot easier to read.
Hopefully, it will work for you.

I was having this problem on a new Linux Ubuntu install and noticed I was getting an error about 'too many watchers for limit' in VSCode at the same time. I followed the instructions to fix it in VSCode and it also fixed the issue with ng watch. More info here https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc
I noticed people suggesting sudo
to run watch. This is a dangerous game, you are giving npm packages root access to your system. If your permissions are correct, my issue could be your fix since the limit is per user, and by running as sudo, you are running as root instead of your current user that is past the limit (running a watch heavy ide like vscode or atom on ). If for some reason you have the wrong permissions, set them properly to your user / group with chown
.
Fastest way to do this is using "SELECT INTO" command e.g.
SELECT * INTO #TempTableName
FROM....
This will create a new table, you don't have to create it in advance.
Just to summarize all the solutions that worked for me in all browsers:
Set a max-width for the infowindow:
this.infowindow = new google.maps.InfoWindow({
maxWidth: 200
});
Wrap the contents of the infowindow with
<div style="overflow:hidden;line-height:1.35;min-width:200px;">*CONTENT*</div>
(change the min-width for the value you set on the infowindow maxWidth)
I have tested it and it worked on every browser, and I had over 400 markers...
He who is Shy* gave you the germ of an answer, but only the germ. The basic technique for converting a value into a string in the C pre-processor is indeed via the '#' operator, but a simple transliteration of the proposed solution gets a compilation error:
#define TEST_FUNC test_func
#define TEST_FUNC_NAME #TEST_FUNC
#include <stdio.h>
int main(void)
{
puts(TEST_FUNC_NAME);
return(0);
}
The syntax error is on the 'puts()' line - the problem is a 'stray #' in the source.
In section 6.10.3.2 of the C standard, 'The # operator', it says:
Each # preprocessing token in the replacement list for a function-like macro shall be followed by a parameter as the next preprocessing token in the replacement list.
The trouble is that you can convert macro arguments to strings -- but you can't convert random items that are not macro arguments.
So, to achieve the effect you are after, you most certainly have to do some extra work.
#define FUNCTION_NAME(name) #name
#define TEST_FUNC_NAME FUNCTION_NAME(test_func)
#include <stdio.h>
int main(void)
{
puts(TEST_FUNC_NAME);
return(0);
}
I'm not completely clear on how you plan to use the macros, and how you plan to avoid repetition altogether. This slightly more elaborate example might be more informative. The use of a macro equivalent to STR_VALUE is an idiom that is necessary to get the desired result.
#define STR_VALUE(arg) #arg
#define FUNCTION_NAME(name) STR_VALUE(name)
#define TEST_FUNC test_func
#define TEST_FUNC_NAME FUNCTION_NAME(TEST_FUNC)
#include <stdio.h>
static void TEST_FUNC(void)
{
printf("In function %s\n", TEST_FUNC_NAME);
}
int main(void)
{
puts(TEST_FUNC_NAME);
TEST_FUNC();
return(0);
}

Update: Yes, I understand that this answer does not explain the difference between arm64 and armhf. There is a great answer that does explain that on this page. This answer was intended to help set the asker on the right path, as they clearly had a misunderstanding about the capabilities of the Raspberry Pi at the time of asking.
Where are you seeing that the architecture is armhf? On my Raspberry Pi 3, I get:
$ uname -a
armv7l
Anyway, armv7 indicates that the system architecture is 32-bit. The first ARM architecture offering 64-bit support is armv8. See this table for reference.
You are correct that the CPU in the Raspberry Pi 3 is 64-bit, but the Raspbian OS has not yet been updated for a 64-bit device. 32-bit software can run on a 64-bit system (but not vice versa). This is why you're not seeing the architecture reported as 64-bit.
You can follow the GitHub issue for 64-bit support here, if you're interested.
This one is better, since it takes the globals and locals from the caller:
import sys
def execfile(filename, globals=None, locals=None):
if globals is None:
globals = sys._getframe(1).f_globals
if locals is None:
locals = sys._getframe(1).f_locals
with open(filename, "r") as fh:
exec(fh.read()+"\n", globals, locals)
Try:
$('#mytable').attr('offsetTop')
I had to make some changes to make it work, as some things seem to have changed in the meantime:
Here's a working example, hope this helps (I'm using JodaTime but in this case SimpleDate would be sufficient):
import java.util.Date;
import javax.xml.bind.DatatypeConverter;
import javax.xml.bind.annotation.adapters.XmlAdapter;
import org.joda.time.DateTime;
public class DateAdapter extends XmlAdapter<Object, Object> {
@Override
public Object marshal(Object dt) throws Exception {
return new DateTime((Date) dt).toString("YYYY-MM-dd");
}
@Override
public Object unmarshal(Object s) throws Exception {
return DatatypeConverter.parseDate((String) s).getTime();
}
}
In the xsd, I have followed the excellent references given above, so I have included this xml annotation:
<xsd:appinfo>
<jaxb:schemaBindings>
<jaxb:package name="at.mycomp.xml" />
</jaxb:schemaBindings>
<jaxb:globalBindings>
<jaxb:javaType name="java.util.Date" xmlType="xsd:date"
parseMethod="at.mycomp.xml.DateAdapter.unmarshal"
printMethod="at.mycomp.xml.DateAdapter.marshal" />
</jaxb:globalBindings>
</xsd:appinfo>
There is an easier way. Just pass your string date to the following function, it will give you the day name :)
func getDayNameBy(stringDate: String) -> String
{
let df = NSDateFormatter()
df.dateFormat = "YYYY-MM-dd"
let date = df.dateFromString(stringDate)!
df.dateFormat = "EEEE"
return df.stringFromDate(date);
}
Here's how you do it:
If you define the timezone in your PHP app (as you should), which you can do this way:
date_default_timezone_set('Europe/Paris');
Then it's as simple as:
$yesterday = new DateTime('yesterday'); // will use our default timezone, Paris
echo $yesterday->format('Y-m-d'); // or whatever format you want
(You may want to define a constant or environment variable to store your default timezone.)
Of course you can assign the command to the button as follows, however, if you are making a UI, it is recommended to assign the same command to the "X" button:
def quit(self): # Your exit routine
self.root.destroy()
self.root.protocol("WM_DELETE_WINDOW", self.quit) # Sets the command for the "X" button
Button(text="Quit", command=self.quit) # No ()
Another potential use is as an alternative to stashing (which some people don't like, see e.g. https://codingkilledthecat.wordpress.com/2012/04/27/git-stash-pop-considered-harmful/).
For example, if I'm working on a branch and need to fix something urgently on master, I can just do:
git commit -am "In progress."
then checkout master and do the fix. When I'm done, I return to my branch and do
git reset --soft HEAD~1
to continue working where I left off.
If you connect with the server, then you can get a return code from it, otherwise it will fail and you get a 0. So if you try to connect to "www.google.com/lksdfk" you will get a return code of 400, if you go directly to google.com, you will get 302 (and then 200 if you forward to the next page... well I do because it forwards to google.com.br, so you might not get that), and if you go to "googlecom" you will get a 0 (host no found), so with the last one, there is nobody to send a code back.
Tested using the code below.
<?php
$html_brand = "www.google.com";
$ch = curl_init();
$options = array(
CURLOPT_URL => $html_brand,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HEADER => true,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_ENCODING => "",
CURLOPT_AUTOREFERER => true,
CURLOPT_CONNECTTIMEOUT => 120,
CURLOPT_TIMEOUT => 120,
CURLOPT_MAXREDIRS => 10,
);
curl_setopt_array( $ch, $options );
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ( $httpCode != 200 ){
echo "Return code is {$httpCode} \n"
.curl_error($ch);
} else {
echo "<pre>".htmlspecialchars($response)."</pre>";
}
curl_close($ch);
EDIT: Looking at the replies so far, it seems that Tortoise will only do it right if it's a file that's already versioned. That's not the case here. I need to be able to apply a patch to a file that did not come out of an SVN repository. I just tried using Tortoise because I happen to know that SVN uses diffs and has to know how to both create them and apply them.
You can install Cygwin, then use the command-line patch tool to apply the patch. See also this Unix man page, which applies to patch.
In the nav go View => Layout => Columns:2
(alt+shift+2
) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py
)
It appears you can also reopen the file using the command File -> New View into File
which will open the current file in a new tab
Like this:
void * p = (void *)0x28ff44;
Or if you want it as a char *
:
char * p = (char *)0x28ff44;
...etc.
If you're pointing to something you really, really aren't meant to change, add a const
:
const void * p = (const void *)0x28ff44;
const char * p = (const char *)0x28ff44;
...since I figure this must be some kind of "well-known address" and those are typically (though by no means always) read-only.
FYI: there is a function args(), which retrieves the arguments of R functions, not to be confused with a vector of arguments named args
Since Version 0.7.7 there is a new way to create an aggregated report:
You create a separate 'report' project which collects all the necessary reports (Any goal in the aggregator project is executed before its modules therefore it can't be used).
aggregator pom
|- parent pom
|- module a
|- module b
|- report module
The root pom looks like this (don't forget to add the new report module under modules):
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.8</version>
<executions>
<execution>
<id>prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
The poms from each sub module doesn't need to be changed at all. The pom from the report module looks like this:
<!-- Add all sub modules as dependencies here -->
<dependencies>
<dependency>
<module a>
</dependency>
<dependency>
<module b>
</dependency>
...
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.8</version>
<executions>
<execution>
<id>report-aggregate</id>
<phase>verify</phase>
<goals>
<goal>report-aggregate</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>

Here is a recursive way on how to do it using ternary operators both for the recursion and decision whether you came across a min number or not.
const findMin = (arr, min, i) => arr.length === i ? min :
findMin(arr, min = arr[i] < min ? arr[i] : min, ++i)
Code snippet:
const findMin = (arr, min, i) => arr.length === i ? min :_x000D_
findMin(arr, min = arr[i] < min ? arr[i] : min, ++i)_x000D_
_x000D_
const arr = [5, 34, 2, 1, 6, 7, 9, 3];_x000D_
const min = findMin(arr, arr[0], 0)_x000D_
console.log(min);
_x000D_
Here are some options:
Or you can check this list of PHP editor reviews.
Sometimes, you may want to conditionally set the height of a div, such as when the entire content is less than the height of the screen. Setting all parent elements to 100% will cut off content when it is longer than the screen size.
So, the way to get around this is to set the min-height:
Continue to let the parent elements automatically adjust their height Then in your main div, subtract the pixel sizes of the header and footer div from 100vh (viewport units). In css, something like:
min-height: calc(100vh - 246px);
100vh is full length of the screen, minus the surrounding divs. By setting min-height and not height, content longer than screen will continue to flow, instead of getting cut off.
To add to the above correct answer :-
For my case in shell, this code worked (working on sqoop
)
ROOT_PATH="path/to/the/folder"
--options-file $ROOT_PATH/query.txt
my_list = sorted(dict.items(), key=lambda x: x[1])
If you are looking for converting Large integers i.e. Numbers greater than Number.MAX_SAFE_INTEGER -- 9007199254740991, then you can use the following code
const hugeNumber = "9007199254740991873839" // Make sure its in String_x000D_
const hexOfHugeNumber = BigInt(hugeNumber).toString(16);_x000D_
console.log(hexOfHugeNumber)
_x000D_
You can also use CircleAvatar
, which comes with flutter
CircleAvatar(
radius: 20,
backgroundImage: NetworkImage('https://via.placeholder.com/140x100')
)
You can use Web SQL API which is an ordinary SQLite database in your browser and you can open/modify it like any other SQLite databases for example with Lita.
Chrome locates databases automatically according to domain names or extension id. A few months ago I posted on my blog short article on how to delete Chrome's database because when you're testing some functionality it's quite useful.
Because I recently needed this, I looked at the source of the answer in:
c# extend class by adding properties
and created a more dynamic version:
public static class ObjectExtenders
{
static readonly ConditionalWeakTable<object, List<stringObject>> Flags = new ConditionalWeakTable<object, List<stringObject>>();
public static string GetFlags(this object objectItem, string key)
{
return Flags.GetOrCreateValue(objectItem).Single(x => x.Key == key).Value;
}
public static void SetFlags(this object objectItem, string key, string value)
{
if (Flags.GetOrCreateValue(objectItem).Any(x => x.Key == key))
{
Flags.GetOrCreateValue(objectItem).Single(x => x.Key == key).Value = value;
}
else
{
Flags.GetOrCreateValue(objectItem).Add(new stringObject()
{
Key = key,
Value = value
});
}
}
class stringObject
{
public string Key;
public string Value;
}
}
It can probably be improved a lot (naming, dynamic instead of string), I currently use this in CF 3.5 together with a hacky ConditionalWeakTable (https://gist.github.com/Jan-WillemdeBruyn/db79dd6fdef7b9845e217958db98c4d4)

This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:
SELECT
s.Name AS SchemaName,
t.NAME AS TableName,
p.rows AS RowCounts,
SUM(a.total_pages) * 8 AS TotalSpaceKB,
SUM(a.used_pages) * 8 AS UsedSpaceKB,
(SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM
sys.tables t
INNER JOIN
sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN
sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN
sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN
sys.allocation_units a ON p.partition_id = a.container_id
WHERE
t.NAME NOT LIKE 'dt%' -- filter out system tables for diagramming
AND t.is_ms_shipped = 0
AND i.OBJECT_ID > 255
GROUP BY
t.Name, s.Name, p.Rows
ORDER BY
s.Name, t.Name
If you want to separate table space from index space, you need to use AND i.index_id IN (0,1)
for the table space (index_id = 0
is the heap space, index_id = 1
is the size of the clustered index = data pages) and AND i.index_id > 1
for the index-only space
Very basic model with Gender field. GetGenderSelectItems()
returns select items needed to populate DropDownList.
public enum Gender
{
Male, Female
}
public class MyModel
{
public Gender Gender { get; set; }
public static IEnumerable<SelectListItem> GetGenderSelectItems()
{
yield return new SelectListItem { Text = "Male", Value = "Male" };
yield return new SelectListItem { Text = "Female", Value = "Female" };
}
}
Please make sure you wrapped your @Html.DropDownListFor
in a form tag.
@model MyModel
@using (Html.BeginForm("MyController", "MyAction", FormMethod.Post)
{
@Html.DropDownListFor(m => m.Gender, MyModel.GetGenderSelectItems())
<input type="submit" value="Send" />
}
Your .cshtml Razor view name should be the same as controller action name and folder name should match controller name e.g Views\MyController\MyAction.cshtml
.
public class MyController : Controller
{
public ActionResult MyAction()
{
// shows your form when you load the page
return View();
}
[HttpPost]
public ActionResult MyAction(MyModel model)
{
// the value is received in the controller.
var selectedGender = model.Gender;
return View(model);
}
}
Now let's make it strongly-typed and enum independent:
var genderSelectItems = Enum.GetValues(typeof(Gender))
.Cast<string>()
.Select(genderString => new SelectListItem
{
Text = genderString,
Value = genderString,
}).AsEnumerable();
