I think MaxScript, the scripting language which comes with 3d studio MAX, I never could see any logic to its syntax
I would use:
awk 'FNR <= 1' file_*.txt
As @Kusalananda points out there are many ways to capture the first line in command line but using the head -n 1
may not be the best option when using wildcards since it will print additional info. Changing 'FNR == i'
to 'FNR <= i'
allows to obtain the first i lines.
For example, if you have n files named file_1.txt, ... file_n.txt:
awk 'FNR <= 1' file_*.txt
hello
...
bye
But with head
wildcards print the name of the file:
head -1 file_*.txt
==> file_1.csv <==
hello
...
==> file_n.csv <==
bye
In Eclipse Ganymede (Subclipse)
Select project/file that contains bad change, and from pop-up menu choose:
Team -> Show History
Revisions related to that project/file will be shown in History tab.
Find revision where "bad changes" were committed and from pop-up menu choose:
Revert Changes from Revision X
This will merge changes in file(s) modified within bad revision, with revision prior to bad revision.
There are two scenarios from here:
If you committed no changes for that file (bad revision is last revision for that file), it will simply remove changes made in bad revision. Those changes are merged to your working copy so you have to commit them.
If you committed some changes for that file (bad revision is not last revision for that file), you will have to manually resolve conflict. Let say that you have file readme.txt with, and bad revision number is 33. Also, you've made another commit for that file in revision 34. After you choose Revert Changes from Revision 33 you will have following in your working copy:
readme.txt.merge-left.r33 - bad revision
readme.txt.merge-right.r32 - before bad revision
readme.txt.working - working copy version (same as in r34 if you don't have any uncommitted changes)
Original readme.txt will be marked conflicted, and will contain merged version (where changes from bad revision are removed) with some markers (<<<<<<< .working etc). If you just want to remove changes from bad revision and keep changes made after that, then all you have to do is remove markers. Otherwise, you can copy contents from one of 3 files mentioned above to original file. Whatever you choose, when you are done, mark conflict resolved by
Team - Mark Resolved
Temporary files will be removed and your file will be marked changed. As in 1, you have to commit changes.
Note that this does not remove revision from revision history in svn repository. You simply made new revision where changes from bad revision are removed.
LogisticRegression
is not for regression but classification !
The Y
variable must be the classification class,
(for example 0
or 1
)
And not a continuous
variable,
that would be a regression problem.
I found that in my code when I used a ration or percentage for line-height line-height;1.5;
My page would scale in such a way that lower case font and upper case font would take up different page heights (I.E. All caps took more room than all lower). Normally I think this looks better, but I had to go to a fixed height line-height:24px;
so that I could predict exactly how many pixels each page would take with a given number of lines.
Javascript arrays have a length property. Use it like this:
st.itemb.length
Android will not let you do this for security concerns. An evil developer could very easily steal user-entered login information.
Instead, you have to catch the text being displayed in the webview before it is displayed. If you don't want to set up a response handler (as per the other answers), I found this fix with some googling:
URL url = new URL("https://stackoverflow.com/questions/1381617");
URLConnection con = url.openConnection();
Pattern p = Pattern.compile("text/html;\\s+charset=([^\\s]+)\\s*");
Matcher m = p.matcher(con.getContentType());
/* If Content-Type doesn't match this pre-conception, choose default and
* hope for the best. */
String charset = m.matches() ? m.group(1) : "ISO-8859-1";
Reader r = new InputStreamReader(con.getInputStream(), charset);
StringBuilder buf = new StringBuilder();
while (true) {
int ch = r.read();
if (ch < 0)
break;
buf.append((char) ch);
}
String str = buf.toString();
This is a lot of code, and you should be able to copy/paster it, and at the end of it str
will contain the same html drawn in the webview. This answer is from Simplest way to correctly load html from web page into a string in Java and it should work on Android as well. I have not tested this and did not write it myself, but it might help you out.
Also, the URL this is pulling is hardcoded, so you'll have to change that.
I believe I found the right answers from here.
So in general it says this:

That is for version 10.0.15-MariaDB, installed through Wnmp ver. 2.1.5.0 on Windows 7 x86
At the click on the image in System tray, you can verify if the frame is visible and then you have to set Visible = true or false
This works because the it's a static variable. You could do something much cooler like this:
filename="filename"
extension="txt"
for i in {1..20}; do
eval "filename${i}=${filename}${i}.${extension}"
touch filename${i}
echo "this rox" > filename${i}
done
This code will create 20 files and dynamically set 20 variables. Of course you could use an array, but I'm just showing you the feature :). Note that you can use the variables $filename1, $filename2, $filename3... because they were created with evaluate command. In this case I'm just creating files, but you could use to create dynamically arguments to the commands, and then execute in background.
For a larger set of environment variables or when you want to reuse them you can use env-cmd
.
./.env
file:

ENV2=FOR ALL
ENV3=THE FISH

:

HOW TO FIND IT?
Give Safe User Permission To Use Port 80
Remember, we do NOT want to run your applications as the root user, but there is a hitch: your safe user does not have permission to use the default HTTP port (80). You goal is to be able to publish a website that visitors can use by navigating to an easy to use URL like http://ip:port/
Unfortunately, unless you sign on as root, you’ll normally have to use a URL like http://ip:port
- where port number > 1024.
A lot of people get stuck here, but the solution is easy. There a few options but this is the one I like. Type the following commands:
sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``
Now, when you tell a Node application that you want it to run on port 80, it will not complain.

Java 14 has added support for Records, which are structured data types that are very easy to build.
You can declare a Java record like this:
public record AuditInfo(
LocalDateTime createdOn,
String createdBy,
LocalDateTime updatedOn,
String updatedBy
) {}
public record PostInfo(
Long id,
String title,
AuditInfo auditInfo
) {}
And, the Java compiler will generate the following Java class associated to the AuditInfo
Record:
public final class PostInfo
extends java.lang.Record {
private final java.lang.Long id;
private final java.lang.String title;
private final AuditInfo auditInfo;
public PostInfo(
java.lang.Long id,
java.lang.String title,
AuditInfo auditInfo) {
/* compiled code */
}
public java.lang.String toString() { /* compiled code */ }
public final int hashCode() { /* compiled code */ }
public final boolean equals(java.lang.Object o) { /* compiled code */ }
public java.lang.Long id() { /* compiled code */ }
public java.lang.String title() { /* compiled code */ }
public AuditInfo auditInfo() { /* compiled code */ }
}
public final class AuditInfo
extends java.lang.Record {
private final java.time.LocalDateTime createdOn;
private final java.lang.String createdBy;
private final java.time.LocalDateTime updatedOn;
private final java.lang.String updatedBy;
public AuditInfo(
java.time.LocalDateTime createdOn,
java.lang.String createdBy,
java.time.LocalDateTime updatedOn,
java.lang.String updatedBy) {
/* compiled code */
}
public java.lang.String toString() { /* compiled code */ }
public final int hashCode() { /* compiled code */ }
public final boolean equals(java.lang.Object o) { /* compiled code */ }
public java.time.LocalDateTime createdOn() { /* compiled code */ }
public java.lang.String createdBy() { /* compiled code */ }
public java.time.LocalDateTime updatedOn() { /* compiled code */ }
public java.lang.String updatedBy() { /* compiled code */ }
}
Notice that the constructor, accessor methods, as well as equals
, hashCode
, and toString
are created for you, so it's very convenient to use Java Records.
A Java Record can be created like any other Java object:
PostInfo postInfo = new PostInfo(
1L,
"High-Performance Java Persistence",
new AuditInfo(
LocalDateTime.of(2016, 11, 2, 12, 0, 0),
"Vlad Mihalcea",
LocalDateTime.now(),
"Vlad Mihalcea"
)
);

First, you need the $
to access "myFold"'s value to make the code in the question work:
cd "$myFold"
To simplify this you create an alias in ~/.bashrc
:
alias cdmain='cd ~/Files/Scripts/Main'
Don't forget to source the .bashrc
once to make the alias become available in the current bash session:
source ~/.bashrc
Now you can change to the folder using:
cdmain
This is my benchmark results

indexOf 6,230,325 ops/sec ±0.95% (62 runs sampled)
test method is faster than the match method, but the fastest method is the indexOf
I had a need for an extended version of this: instead of embedding a single number in a string, I needed to generate a series of file names of the form 'file1.pdf', 'file2.pdf' etc. This is how it worked:
['file' + str(i) + '.pdf' for i in range(1,4)]
Well its very simple in controller you have somthing like this:
-- Controller
ViewBag.Profile_Id = new SelectList(db.Profiles, "Id", "Name", model.Profile_Id);
--View (Option A)
@Html.DropDownList("Profile_Id")
--View (Option B) --> Send a null value to the list
@Html.DropDownList("Profile_Id", null, "-- Choose --", new { @class = "input-large" })
You're getting None
because list.sort()
it operates in-place, meaning that it doesn't return anything, but modifies the list itself. You only need to call a.sort()
without assigning it to a
again.
There is a built in function sorted()
, which returns a sorted version of the list - a = sorted(a)
will do what you want as well.
Just adding .First
to your bananaToken
should do it:
foodJsonObj["food"]["fruit"]["orange"].Parent.AddAfterSelf(bananaToken
.First
);
.First
basically moves past the {
to make it a JProperty
instead of a JToken
.
@Brian Rogers, Thanks I forgot the .Parent
. Edited
You can use "data-123".replace('data-','');
, as mentioned, but as replace()
only replaces the FIRST instance of the matching text, if your string was something like "data-123data-"
then
"data-123data-".replace('data-','');
will only replace the first matching text. And your output will be "123data-"
So if you want all matches of text to be replaced in string you have to use a regular expression with the g
flag like that:
"data-123data-".replace(/data-/g,'');
And your output will be "123"
If you want to add CSS on a:hover
to not all the tag, but the some of the tag, best way to do that is by using class. Give the class to all the tags which you want to give style - see the example below.
<style>
a.change_hover_color:hover {
color: white !important;
}
</style>
<a class="change_hover_color">FACEBOOK</a>
<a class="change_hover_color">GOOGLE</a>
You can use String.getBytes()
which returns the byte[]
array.

This would do the trick, returning the values at indeces 0, 2 and 3.

By adding fragment_tran.addToBackStack(null)
on last fragment, I am able to do come back on last fragment.
adding new fragment:
view.findViewById(R.id.changepass).setOnClickListener(new View.OnClickListener() {

FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container, new ChangePassword());
transaction.addToBackStack(null);
transaction.commit();
}
});
You are able to cut all odd/even columns by using seq:
This would print all odd columns
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 1 2 10)
To print all even columns you could use
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 2 2 10)
By changing the second number of seq you can specify which columns to be printed.
If the specification which columns to print is more complex you could also use a "one-liner-if-clause" like
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(for i in $(seq 1 10); do if [[ $i -lt 10 && $i -lt 5 ]];then echo -n $i,; else echo -n $i;fi;done)
This would print all columns from 1 to 5 - you can simply modify the conditions to create more complex conditions to specify weather a column shall be printed.
On the Admin panel in the footer you should see the words "Wordpress x.x" where x.x is your version number :)

Nowadays at least with android it's relatively easy. Just use normal file input tag and when user clicks it the phone will ask if user wants to use camera (or file managers etc..) to upload a file. Just take a photo with the camera and it will automatically be added and uploaded.
No idea about iphone. Maybe someone can enlighten on that. EDIT: Iphone works similarly.
Sample of the input tag:
<input type="file" accept="image/*" capture="camera">

I have just encountered a similar need. In my case, slf4j is configured with the java logging adapter (the jdk14 one). Using the following code snippet I have managed to change the debug level at runtime:
Logger logger = LoggerFactory.getLogger("testing");
java.util.logging.Logger julLogger = java.util.logging.Logger.getLogger("testing");
julLogger.setLevel(java.util.logging.Level.FINE);
logger.debug("hello world");
This should work:
DECLARE db_cursor CURSOR FOR SELECT name, age, color FROM table;
DECLARE @myName VARCHAR(256);
DECLARE @myAge INT;
DECLARE @myFavoriteColor VARCHAR(40);
OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
WHILE @@FETCH_STATUS = 0
BEGIN
--Do stuff with scalar values
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;
I've forked a CodePen demo that had the same problem with embedding inline SVG into CSS. A solution that works with SCSS is to build a simple url-encoding function.
A string replacement function can be created from the built-in str-slice, str-index functions (see css-tricks, thanks to Hugo Giraudel).
Then, just replace %
,<
,>
,"
,'
, with the
%xx
codes:
@function svg-inline($string){
$result: str-replace($string, "<svg", "<svg xmlns='http://www.w3.org/2000/svg'");
$result: str-replace($result, '%', '%25');
$result: str-replace($result, '"', '%22');
$result: str-replace($result, "'", '%27');
$result: str-replace($result, ' ', '%20');
$result: str-replace($result, '<', '%3C');
$result: str-replace($result, '>', '%3E');
@return "data:image/svg+xml;utf8," + $result;
}
$mySVG: svg-inline("<svg>...</svg>");
html {
height: 100vh;
background: url($mySVG) 50% no-repeat;
}
There is also a image-inline
helper function available in Compass, but since it is not supported in CodePen, this solution might probably be useful.

The code proved to be handy on several occasions now and I feel the expense to get into customization as usage is quite low. Thus, I decided to release it under MIT license and provide a GitHub repository where the header and a small example file can be downloaded.
A 'decoration' in terms of this answer is a set of prefix-string, delimiter-string, and a postfix-string. Where the prefix string is inserted into a stream before and the postfix string after the values of a container (see 2. Target containers). The delimiter string is inserted between the values of the respective container.
Note: Actually, this answer does not address the question to 100% since the decoration is not strictly compiled time constant because runtime checks are required to check whether a custom decoration has been applied to the current stream. Nevertheless, I think it has some decent features.
Note2: May have minor bugs since it is not yet well tested.
It is to be kept as easy as
#include <vector>
#include "pretty.h"
int main()
{
std::cout << std::vector<int>{1,2,3,4,5}; // prints 1, 2, 3, 4, 5
return 0;
}
... with respect to a specific stream object
#include <vector>
#include "pretty.h"
int main()
{
// set decoration for std::vector<int> for cout object
std::cout << pretty::decoration<std::vector<int>>("(", ",", ")");
std::cout << std::vector<int>{1,2,3,4,5}; // prints (1,2,3,4,5)
return 0;
}
or with respect to all streams:
#include <vector>
#include "pretty.h"
// set decoration for std::vector<int> for all ostream objects
PRETTY_DEFAULT_DECORATION(std::vector<int>, "{", ", ", "}")
int main()
{
std::cout << std::vector<int>{1,2,3,4,5}; // prints {1, 2, 3, 4, 5}
std::cout << pretty::decoration<std::vector<int>>("(", ",", ")");
std::cout << std::vector<int>{1,2,3,4,5}; // prints (1,2,3,4,5)
return 0;
}
ios_base
using xalloc
/pword
in order to save a pointer to a pretty::decor
object specifically decorating a certain type on a certain stream.If no pretty::decor<T>
object for this stream has been set up explicitly pretty::defaulted<T, charT, chartraitT>::decoration()
is called to obtain the default decoration for the given type.
The class pretty::defaulted
is to be specialized to customize default decorations.
Target objects obj
for the 'pretty decoration' of this code are objects having either
std::begin
and std::end
defined (includes C-Style arrays),begin(obj)
and end(obj)
available via ADL,std::tuple
std::pair
.The code includes a trait for identification of classes with range features (begin
/end
).
(There's no check included, whether begin(obj) == end(obj)
is a valid expression, though.)
The code provides operator<<
s in the global namespace that only apply to classes not having a more specialized version of operator<<
available.
Therefore, for example std::string
is not printed using the operator in this code although having a valid begin
/end
pair.
Decorations can be imposed separately for every type (except different tuple
s) and stream (not stream type!).
(I.e. a std::vector<int>
can have different decorations for different stream objects.)
The default prefix is ""
(nothing) as is the default postfix, while the default delimiter is ", "
(comma+space).
pretty::defaulted
class templateThe struct defaulted
has a static member function decoration()
returning a decor
object which includes the default values for the given type.
Customize default array printing:
namespace pretty
{
template<class T, std::size_t N>
struct defaulted<T[N]>
{
static decor<T[N]> decoration()
{
return{ { "(" }, { ":" }, { ")" } };
}
};
}
Print an arry array:
float e[5] = { 3.4f, 4.3f, 5.2f, 1.1f, 22.2f };
std::cout << e << '\n'; // prints (3.4:4.3:5.2:1.1:22.2)
PRETTY_DEFAULT_DECORATION(TYPE, PREFIX, DELIM, POSTFIX, ...)
macro for char
streamsThe macro expands to
namespace pretty {
template< __VA_ARGS__ >
struct defaulted< TYPE > {
static decor< TYPE > decoration() {
return { PREFIX, DELIM, POSTFIX };
}
};
}
enabling the above partial specialization to be rewritten to
PRETTY_DEFAULT_DECORATION(T[N], "", ";", "", class T, std::size_t N)
or inserting a full specialization like
PRETTY_DEFAULT_DECORATION(std::vector<int>, "(", ", ", ")")
Another macro for wchar_t
streams is included: PRETTY_DEFAULT_WDECORATION
.
The function pretty::decoration
is used to impose a decoration on a certain stream.
There are overloads taking either
- one string argument being the delimiter (adopting prefix and postfix from the defaulted class)
- or three string arguments assembling the complete decoration
float e[3] = { 3.4f, 4.3f, 5.2f };
std::stringstream u;
// add { ; } decoration to u
u << pretty::decoration<float[3]>("{", "; ", "}");
// use { ; } decoration
u << e << '\n'; // prints {3.4; 4.3; 5.2}
// uses decoration returned by defaulted<float[3]>::decoration()
std::cout << e; // prints 3.4, 4.3, 5.2
PRETTY_DEFAULT_DECORATION(float[3], "{{{", ",", "}}}")
std::stringstream v;
v << e; // prints {{{3.4,4.3,5.2}}}
v << pretty::decoration<float[3]>(":");
v << e; // prints {{{3.4:4.3:5.2}}}
v << pretty::decoration<float[3]>("((", "=", "))");
v << e; // prints ((3.4=4.3=5.2))
std::tuple
Instead of allowing a specialization for every possible tuple type, this code applies any decoration available for std::tuple<void*>
to all kind of std::tuple<...>
s.
To go back to the defaulted decoration for a given type use pretty::clear
function template on the stream s
.
s << pretty::clear<std::vector<int>>();
Printing "matrix-like" with newline delimiter
std::vector<std::vector<int>> m{ {1,2,3}, {4,5,6}, {7,8,9} };
std::cout << pretty::decoration<std::vector<std::vector<int>>>("\n");
std::cout << m;
Prints
1, 2, 3
4, 5, 6

I prefer to use other variant for accessing.
From parent you can have a access to variable in child iframe.
$
is a variable too and you can receive access to its just call
window.iframe_id.$
For example, window.view.$('div').hide()
- hide all divs in iframe with id 'view'
But, it doesn't work in FF. For better compatibility you should use
$('#iframe_id')[0].contentWindow.$
look at familiar main method which takes string array as param
In addition to this answer, note that in Node.js if you access JSON with the array syntax []
all nested JSON keys should follow that syntax
This is the wrong way
json.first.second.third['comment']
and will will give you the 'undefined' error.
This is the correct way
json['first']['second']['third']['comment']
From iOS 11 Photos framework allows to add animated Gifs playback.

Add:
using System.Linq;
to the top of your file.
And then:
Car[] carList = ...
var carMake =
from item in carList
where item.Model == "bmw"
select item.Make;
or if you prefer the fluent syntax:
var carMake = carList
.Where(item => item.Model == "bmw")
.Select(item => item.Make);
Things to pay attention to:
item.Make
in the select
clause instead if s.Make
as in your code.item
and .Model
in your where
clauseThere's a .val()
method:
If you've got an input with an id of txtEmail
you can use the following code to access the value of the text box:
$("#txtEmail").val()
You can also use the val(string)
method to set that value:
$("#txtEmail").val("something")
I'm not sure exactly what the problem is, but I have looked at one of my jnlp files and I have put in the full path to each of my jar files. (I have a velocity template that generates the app.jnlp file which places it in all the correct places when my maven build runs)
One thing I have seen happen is that the jnlp file is re-downloaded by the by the webstart runtime, and it uses the href attribute (which is left blank in your jnlp file) to re-download the file. I would start there, and try adding the full path into the jnlp files too...I've found webstart to be a fickle mistress!
The problem can be PHP configuration:
Please check the setting max_input_vars in the php.ini file.
Try to increase the value of this setting to 5000 as example.
max_input_vars = 5000
Then restart your web-server and try.
I try to make it available to all object like this:
Object.defineProperty(Object.prototype, "length", {
get() {
if (!Object.keys) {
Object.keys = function (obj) {
var keys = [],k;
for (k in obj) {
if (Object.prototype.hasOwnProperty.call(obj, k)) {
keys.push(k);
}
}
return keys;
};
}
return Object.keys(this).length;
},});
console.log({"Name":"Joe","Age":26}.length) //returns 2
The main problem was that you were opening/closing files repeatedly inside your loop.
Try this approach:
with open('new.txt') as text_file, open('xyz.txt', 'w') as myfile:
for line in text_file:
var1, var2 = line.split(",");
myfile.write(var1+'\n')
We open both files at once and because we are using with
they will be automatically closed when we are done (or an exception occurs). Previously your output file was repeatedly openend inside your loop.
We are also processing the file line-by-line, rather than reading all of it into memory at once (which can be a problem when you deal with really big files).
Note that write()
doesn't append a newline ('\n'
) so you'll have to do that yourself if you need it (I replaced your writelines()
with write()
as you are writing a single item, not a list of items).
When opening a file for r
read, the 'r'
is optional since it's the default mode.
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');
I've had to do this a few times to-date. Note that this only works on 1 file at a time.
Get a list of all commits that modified a file. The one at the bottom will the the first commit:
git log --pretty=oneline --branches -- pathToFile
To remove the file from history use the first commit sha1 and the path to file from the previous command, and fill them into this command:
git filter-branch --index-filter 'git rm --cached --ignore-unmatch <path-to-file>' -- <sha1-where-the-file-was-first-added>..
You can also do it by targeting the current input, with anything.target.reset()
. This is the most easiest way!
handleSubmit(e){
e.preventDefault();
e.target.reset();
}
<form onSubmit={this.handleSubmit}>
...
</form>
Try using the onbeforeunload property, which will let the user choose whether he wants to navigate away from the page.

In HTML5 you can use sandbox property. Please see Pankrat's answer below. http://www.html5rocks.com/en/tutorials/security/sandboxed-iframes/
You need to add your source files with git add
or the GUI equivalent so that Git will begin tracking them.
Use git status
to see what Git thinks about the files in any given directory.
def findMaxSales(listoftuples):
newlist = []
tuple = ()
for item in listoftuples:
movie = item[0]
value = (item[1])
tuple = value, movie
newlist += [tuple]
newlist.sort()
highest = newlist[-1]
result = highest[1]
return result
movieList = [("Finding Dory", 486), ("Captain America: Civil
War", 408), ("Deadpool", 363), ("Zootopia", 341), ("Rogue One", 529), ("The Secret Life of Pets", 368), ("Batman v Superman", 330), ("Sing", 268), ("Suicide Squad", 325), ("The Jungle Book", 364)]
print(findMaxSales(movieList))
output --> Rogue One
You can also find useful information about getView at the Adapter interface in Adapter.java file. It says;
/**
* Get a View that displays the data at the specified position in the data set. You can either
* create a View manually or inflate it from an XML layout file. When the View is inflated, the
* parent View (GridView, ListView...) will apply default layout parameters unless you use
* {@link android.view.LayoutInflater#inflate(int, android.view.ViewGroup, boolean)}
* to specify a root view and to prevent attachment to the root.
*
* @param position The position of the item within the adapter's data set of the item whose view
* we want.
* @param convertView The old view to reuse, if possible. Note: You should check that this view
* is non-null and of an appropriate type before using. If it is not possible to convert
* this view to display the correct data, this method can create a new view.
* Heterogeneous lists can specify their number of view types, so that this View is
* always of the right type (see {@link #getViewTypeCount()} and
* {@link #getItemViewType(int)}).
* @param parent The parent that this view will eventually be attached to
* @return A View corresponding to the data at the specified position.
*/
View getView(int position, View convertView, ViewGroup parent);
var total = 0; $.each(someArray,function() { total += parseInt(this, 10); });
IF NOT EXISTS (SELECT 1 FROM SYS.COLUMNS WHERE
OBJECT_ID = OBJECT_ID(N'[dbo].[Person]') AND name = 'DateOfBirth')
BEGIN
ALTER TABLE [dbo].[Person] ADD DateOfBirth DATETIME
END
You could drop the primary key column and re-create it. All the ids should then be reassigned in order.
However this is probably a bad idea in most situations. If you have other tables that have foreign keys to this table then it will definitely not work.
after putting "Allow from all", you need to restart your xampp to apply the setting. thanks
You should use HTML5 data attributes. You can create your own attributes and save different values in them.
It annoys me for days. And finally I make use of the CSS property selector to solve it.

In my case, the problem was coming from the execution of WinSAT.exe
(located in System32
folder). I disabled it and issue solved.
To turn it off:
- Start > Task Scheduler (taskschd.msc)
- Find Task Scheduler (Local)
- Task Scheduler Library
- Microsoft > Windows > Maintenance
- Right click WinSAT
- Select disable.
Also, suppress it from Task Manager or simply reboot your machine.
Point: In this situation (when the problem comes from WinSAT
) emulator works (with poor performance) when you use Software - GLES 2.0
and works with very very poor performance when you use Hardware - GLES 2.0
.
This will throw a NullPointerException
- as will any attempt to invoke an instance method on a null
reference - but in cases like this you should make an explicit check against null
:
if ((test != null) && !test.isEmpty())
This is much better, and clearer, than propagating an Exception
.

To get the type of fields in struct
package main
import (
"fmt"
"reflect"
)
type testObject struct {
Name string
Age int
Height float64
}
func main() {
tstObj := testObject{Name: "yog prakash", Age: 24, Height: 5.6}
val := reflect.ValueOf(&tstObj).Elem()
typeOfTstObj := val.Type()
for i := 0; i < val.NumField(); i++ {
fieldType := val.Field(i)
fmt.Printf("object field %d key=%s value=%v type=%s \n",
i, typeOfTstObj.Field(i).Name, fieldType.Interface(),
fieldType.Type())
}
}
Output
object field 0 key=Name value=yog prakash type=string
object field 1 key=Age value=24 type=int
object field 2 key=Height value=5.6 type=float64

As of 2018, there is also iText7 (A next iteration of old iTextSharp library) and its HTML to PDF package available: itext7.pdfhtml
Usage is straightforward:
HtmlConverter.ConvertToPdf(
new FileInfo(@"Path\to\Html\File.html"),
new FileInfo(@"Path\to\Pdf\File.pdf")
);
Method has many more overloads.
Update: iText* family of products has dual licensing model: free for open source, paid for commercial use.
After spending a good amount of time on this issue I found whenever I followed suggestions of using IIS to make a self signed certificate, I found that the Issued To and Issued by was not correct. SelfSSL.exe was the key to solving this problem. The following website not only provided a step by step approach to making self signed certificates, but also solved the Issued To and Issued by problem. Here is the best solution I found for making self signed certificates. If you'd prefer to see the same tutorial in video form click here.
A sample use of SelfSSL would look something like the following:
SelfSSL /N:CN=YourWebsite.com /V:1000 /S:2
SelfSSL /? will provide a list of parameters with explanation.
I imagine this forum posting, which I quote fully below, should answer the question.
Inside a procedure, function, or trigger definition, or in a dynamic SQL statement (embedded in a host program):
BEGIN ATOMIC
DECLARE example VARCHAR(15) ;
SET example = 'welcome' ;
SELECT *
FROM tablename
WHERE column1 = example ;
END
or (in any environment):
WITH t(example) AS (VALUES('welcome'))
SELECT *
FROM tablename, t
WHERE column1 = example
or (although this is probably not what you want, since the variable needs to be created just once, but can be used thereafter by everybody although its content will be private on a per-user basis):
CREATE VARIABLE example VARCHAR(15) ;
SET example = 'welcome' ;
SELECT *
FROM tablename
WHERE column1 = example ;
There is a round()
function, also fround()
, which will round to the nearest integer expressed as a double. But that is not what you want.
I had the same problem and wrote this:
#include <math.h>
double db_round(double value, int nsig)
/* ===============
**
** Rounds double <value> to <nsig> significant figures. Always rounds
** away from zero, so -2.6 to 1 sig fig will become -3.0.
**
** <nsig> should be in the range 1 - 15
*/
{
double a, b;
long long i;
int neg = 0;
if(!value) return value;
if(value < 0.0)
{
value = -value;
neg = 1;
}
i = nsig - log10(value);
if(i) a = pow(10.0, (double)i);
else a = 1.0;
b = value * a;
i = b + 0.5;
value = i / a;
return neg ? -value : value;
}
I had a similar encoding issue. I used the normalize() method. I was getting a Unicode error using the pandas .to_html() method when exporting my data frame to an .html file in another directory. I ended up doing this and it worked...
import unicodedata
The dataframe object can be whatever you like, let's call it table...
table = pd.DataFrame(data,columns=['Name','Team','OVR / POT'])
table.index+= 1
encode table data so that we can export it to out .html file in templates folder(this can be whatever location you wish :))
#this is where the magic happens
html_data=unicodedata.normalize('NFKD',table.to_html()).encode('ascii','ignore')
export normalized string to html file
file = open("templates/home.html","w")
file.write(html_data)
file.close()
Reference: unicodedata documentation
Use the class DecimalFormat, like so:
NumberFormat formatter = new DecimalFormat("0000"); //i use 4 Zero but you can also another number
System.out.println("OUTPUT : "+formatter.format(811));
OUTPUT : 0000811
While CMS is correct that passing strings into the parse method is generally unsafe, the new ECMA-262 5th Edition (aka ES5) specification in section 15.9.4.2 suggests that Date.parse()
actually should handle ISO-formatted dates. The old specification made no such claim. Of course, old browsers and some current browsers still do not provide this ES5 functionality.
Your second example isn't wrong. It is the specified date in UTC, as implied by Date.prototype.toISOString()
, but is represented in your local timezone.
This works in MSSQL and MySQL:
SELECT *
FROM Village
WHERE CastleType LIKE '%foo%';
Here is a nearly complete example javascript function that will allow multiple markers defined in a JSONObject.
It will only display the markers that are with in the bounds of the map.
This is important so you are not doing extra work.
You can also set a limit to the markers so you are not showing an extreme amount of markers (if there is a possibility of a thing in your usage);
it will also not display markers if the center of the map has not changed more than 500 meters.
This is important because if a user clicks on the marker and accidentally drags the map while doing so you don't want the map to reload the markers.
I attached this function to the idle event listener for the map so markers will show only when the map is idle and will redisplay the markers after a different event.

You can set selinux to permissive in order to analyze.
# setenforce 0
Selinux will log but permit acesses. So you can check the /var/log/audit/audit.log
for details. Maybe you will need change selinux context. Fot this, you will use chcon
command. If you need, show us your audit.log
to more detailed answer.
Don't forget to enable selinux after you solved the problem. It better keep selinux enforced.

should be like this
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_07
You can quite simply add the line:
source ~/.profile
To the bottom of your shell rc file - if you are using bash then it would be your ~/.bash_profile if you are using zsh it would be your ~/.zshrc
Then open a new Terminal window and type ports -v you should see output that looks like the following:
~ [ port -v ] 12:12 pm
MacPorts 2.1.3
Entering interactive mode... ("help" for help, "quit" to quit)
[Users/sh] > quit
Goodbye
Hope that helps.
As some have mentioned a possible way is using git interactive staging. This is great when you have files with different extensions
$ git add -i
staged unstaged path
1: unchanged +0/-1 TODO
2: unchanged +1/-1 index.html
3: unchanged +5/-1 lib/simplegit.rb
*** Commands ***
1: status 2: update 3: revert 4: add untracked
5: patch 6: diff 7: quit 8: help
What now>
If you press 2
then enter
you will get a list of available files to be added:
What now> 2
staged unstaged path
1: unchanged +0/-1 TODO
2: unchanged +1/-1 index.html
3: unchanged +5/-1 lib/simplegit.rb
Update>>
Now you just have to insert the number of the files you want to add, so if we wanted to add TODO
and index.html
we would type 1,2
Update>> 1,2
staged unstaged path
* 1: unchanged +0/-1 TODO
* 2: unchanged +1/-1 index.html
3: unchanged +5/-1 lib/simplegit.rb
Update>>
You see the *
before the number? that means that the file was added.
Now imagine that you have 7 files and you want to add them all except the 7th? Sure we could type 1,2,3,4,5,6
but imagine instead of 7 we have 16, that would be quite cumbersome, the good thing we don't need to type them all because we can use ranges,by typing 1-6
Update>> 1-6
staged unstaged path
* 1: unchanged +0/-1 TODO
* 2: unchanged +1/-1 index.html
* 3: unchanged +5/-1 lib/simplegit.rb
* 4: unchanged +5/-1 file4.html
* 5: unchanged +5/-1 file5.html
* 6: unchanged +5/-1 file6.html
7: unchanged +5/-1 file7.html
Update>>
We can even use multiple ranges, so if we want from 1 to 3 and from 5 to 7 we type 1-3, 5-7
:
Update>> 1-3, 5-7
staged unstaged path
* 1: unchanged +0/-1 TODO
* 2: unchanged +1/-1 index.html
* 3: unchanged +5/-1 lib/simplegit.rb
4: unchanged +5/-1 file4.html
* 5: unchanged +5/-1 file5.html
* 6: unchanged +5/-1 file6.html
* 7: unchanged +5/-1 file7.html
Update>>
We can also use this to unstage files, if we type -number
, so if we wanted to unstage file number 1 we would type -1
:
Update>> -1
staged unstaged path
1: unchanged +0/-1 TODO
* 2: unchanged +1/-1 index.html
* 3: unchanged +5/-1 lib/simplegit.rb
4: unchanged +5/-1 file4.html
* 5: unchanged +5/-1 file5.html
* 6: unchanged +5/-1 file6.html
* 7: unchanged +5/-1 file7.html
Update>>
And as you can imagine we can also unstage a range of files, so if we type -range
all the files on that range would be unstaged. If we wanted to unstage all the files from 5 to 7 we would type -5-7
:
Update>> -5-7
staged unstaged path
1: unchanged +0/-1 TODO
* 2: unchanged +1/-1 index.html
* 3: unchanged +5/-1 lib/simplegit.rb
4: unchanged +5/-1 file4.html
5: unchanged +5/-1 file5.html
6: unchanged +5/-1 file6.html
7: unchanged +5/-1 file7.html
Update>>
An example with a little less stringified html:
var container = $('#my-container'),
table = $('<table>');
users.forEach(function(user) {
var tr = $('<tr>');
['ID', 'Name', 'Address'].forEach(function(attr) {
tr.append('<td>' + user[attr] + '</td>');
});
table.append(tr);
});
container.append(table);
With library(lubridate)
, numeric representations of date and time saved as the number of seconds since
1970-01-01 00:00:00 UTC, can be coerced into dates with as_datetime()
:
lubridate::as_datetime(1352068320)
[1] "2012-11-04 22:32:00 UTC"
.class {
/* Fallback for web browsers that doesn't support RGBa */
background: rgb(0, 0, 0);
/* RGBa with 0.6 opacity */
background: rgba(0, 0, 0, 0.6);
}

In my case the mentioned "duplicate entry" error arised after settingmultiDexEnable=true in the build.gradle.
and exact error which i was getting was below :
Error:Execution failed for task
':android:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException:
java.util.zip.ZipException: duplicate entry:
com/google/android/gms/internal/zzqx.class
So first thing I search for class which causes "duplicate entry" error using ctrl+n in Android Studio and searched for com/google/android/gms/internal/zzqx.class and then it was showing 2 entries for gms class with one version 8.4.0 and 1 with version 11.6.0 .
To fix it i made both to use 11.6.0 and it was fixed example
earlier
compile "com.google.android.gms:play-services-games:11.6.0"
compile "com.google.android.gms:play-services-auth:8.4.0"
compile "com.google.android.gms:play-services-ads:11.6.0"
After
compile "com.google.android.gms:play-services-games:11.6.0"
compile "com.google.android.gms:play-services-auth:11.6.0"
compile "com.google.android.gms:play-services-ads:11.6.0"

gcc 7.4.0 can not compile codes as below:
#include <stdio.h>
const char * const str1 = "str1";
const char * str2 = str1;
int main() {
printf("%s - %s\n", str1, str2);
return 0;
}
constchar.c:3:21: error: initializer element is not constant const char * str2 = str1;
In fact, a "const char *" string is not a compile-time constant, so it can't be an initializer. But a "const char * const" string is a compile-time constant, it should be able to be an initializer. I think this is a small drawback of CLang.
A function name is of course a compile-time constant.So this code works:
void func(void)
{
printf("func\n");
}
typedef void (*func_type)(void);
func_type f = func;
int main() {
f();
return 0;
}

-a and -o are the older and/or operators for the test command. && and || are and/or operators for the shell. So (assuming an old shell) in your first case,
[ "$1" = 'yes' ] && [ -r $2.txt ]
The shell is evaluating the and condition. In your second case,
[ "$1" = 'yes' -a $2 -lt 3 ]
The test command (or builtin test) is evaluating the and condition.
Of course in all modern or semi-modern shells, the test command is built in to the shell, so there really isn't any or much difference. In modern shells, the if statement can be written:
[[ $1 == yes && -r $2.txt ]]
Which is more similar to modern programming languages and thus is more readable.
If you look deeper into the other uses of size
you can see that you can actually get a vector of the size of each dimension. This link shows you the documentation:
www.mathworks.com/access/helpdesk/help/techdoc/ref/size.html
After getting the size vector, iterate over that vector. Something like this (pardon my syntax since I have not used Matlab since college):
d = size(m);
dims = ndims(m);
for dimNumber = 1:dims
for i = 1:d[dimNumber]
...
Make this into actual Matlab-legal syntax, and I think it would do what you want.
Also, you should be able to do Linear Indexing as described here.
The accepted solution is going to be extremely slow for lots of data. The solution with the greatest number of upvotes is a little difficult to read and also slow with numeric data. If each new column can be calculated independently of the others, I would just assign each of them directly without using apply
.
Create 100,000 strings in a DataFrame
df = pd.DataFrame(np.random.choice(['he jumped', 'she ran', 'they hiked'],
size=100000, replace=True),
columns=['words'])
df.head()
words
0 she ran
1 she ran
2 they hiked
3 they hiked
4 they hiked
Let's say we wanted to extract some text features as done in the original question. For instance, let's extract the first character, count the occurrence of the letter 'e' and capitalize the phrase.
df['first'] = df['words'].str[0]
df['count_e'] = df['words'].str.count('e')
df['cap'] = df['words'].str.capitalize()
df.head()
words first count_e cap
0 she ran s 1 She ran
1 she ran s 1 She ran
2 they hiked t 2 They hiked
3 they hiked t 2 They hiked
4 they hiked t 2 They hiked
Timings
%%timeit
df['first'] = df['words'].str[0]
df['count_e'] = df['words'].str.count('e')
df['cap'] = df['words'].str.capitalize()
127 ms ± 585 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
def extract_text_features(x):
return x[0], x.count('e'), x.capitalize()
%timeit df['first'], df['count_e'], df['cap'] = zip(*df['words'].apply(extract_text_features))
101 ms ± 2.96 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
Surprisingly, you can get better performance by looping through each value
%%timeit
a,b,c = [], [], []
for s in df['words']:
a.append(s[0]), b.append(s.count('e')), c.append(s.capitalize())
df['first'] = a
df['count_e'] = b
df['cap'] = c
79.1 ms ± 294 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
Create 1 million random numbers and test the powers
function from above.
df = pd.DataFrame(np.random.rand(1000000), columns=['num'])
def powers(x):
return x, x**2, x**3, x**4, x**5, x**6
%%timeit
df['p1'], df['p2'], df['p3'], df['p4'], df['p5'], df['p6'] = \
zip(*df['num'].map(powers))
1.35 s ± 83.6 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
Assigning each column is 25x faster and very readable:
%%timeit
df['p1'] = df['num'] ** 1
df['p2'] = df['num'] ** 2
df['p3'] = df['num'] ** 3
df['p4'] = df['num'] ** 4
df['p5'] = df['num'] ** 5
df['p6'] = df['num'] ** 6
51.6 ms ± 1.9 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
I made a similar response with more details here on why apply
is typically not the way to go.

I successfully opened gstreamer SDK tutorials in Eclipse.
All I needed is to use an older version of ndk. specificly 9d.
(10c and 10d does not work, 10b - works just for tutorial-1 )
9d does work for all tutorials ! and you can:
Download it from: http://dl.google.com/android/ndk/android-ndk-r9d-linux-x86_64.tar.bz2
Extract it.
set it in eclipse->window->preferences->Android->NDK->NDK location.

I'm debugging an issue I'm having with SSL connecting to a database (MySQL RDS) using an ORM called, Prisma. The database connection string requires a PKCS12 (.p12) file (if interested, described here), which brought me here.
I know the question has been answered, but I found the following steps (in Github Issue#2676) to be helpful for creating a .p12 file and wanted to share. Good luck!
Generate 2048-bit RSA private key:
openssl genrsa -out key.pem 2048
Generate a Certificate Signing Request:
openssl req -new -sha256 -key key.pem -out csr.csr
Generate a self-signed x509 certificate suitable for use on web servers.
openssl req -x509 -sha256 -days 365 -key key.pem -in csr.csr -out certificate.pem
Create SSL identity file in PKCS12 as mentioned here
openssl pkcs12 -export -out client-identity.p12 -inkey key.pem -in certificate.pem
You want the Dictionary class.

You need to only add target="_self" to your link
ex. <a href="#services" target="_self">Services</a><div id="services"></div>
map.keySet()
will return you all the keys. If you want the keys to be sorted, you might consider a TreeMap
From the Linux manual page:
h A following integer conversion corresponds to a short int or unsigned short int argument, or a fol- lowing n conversion corresponds to a pointer to a short int argument.
So to print an unsigned short integer, the format string should be "%hu"
.
If you are using CSH or TCSH, here is a solution:
( find . > files_and_folders ) >& /dev/null
If you want output to the terminal:
( find . > /dev/tty ) >& /dev/null
However, as the "csh-whynot" FAQ describes, you should not use CSH.
As in the opencv-doc you can get video feed from a camera which is connected to your computer by following code.
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
# Capture frame-by-frame
ret, frame = cap.read()
# Our operations on the frame come here
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
# Display the resulting frame
cv2.imshow('frame',gray)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()
You can change cap = cv2.VideoCapture(0)
index from 0
to 1
to access the 2nd camera.
Tested in opencv-3.2.0
Called "Destructive Methods" They tend to change the original copy of the object you are referring to.
numbers=[1,0,10,5,8]
numbers.collect{|n| puts n*2} # would multiply each number by two
numbers #returns the same original copy
numbers.collect!{|n| puts n*2} # would multiply each number by two and destructs the original copy from the array
numbers # returns [nil,nil,nil,nil,nil]

You need to pass a filename string to open
. There's an extra complication when the string has \
in it, because that's a special string escape character to Python. You can fix this by doubling up each as \\
or by putting a r
in front of the string as follows: r'C:\name\MyDocuments\numbers'
.
Edit: The edits to the question make it completely different from the original, and since none of them was from the original poster I'm not sure they're warrented. However it does point out one obvious thing that might have been overlooked, and that's how to add "My Documents" to a filename.
In an English version of Windows XP, My Documents
is actually C:\Documents and Settings\name\My Documents
. This means the open
call should look like:
open(r"C:\Documents and Settings\name\My Documents\numbers", 'r')
I presume you're using XP because you call it My Documents
- it changed in Vista and Windows 7. I don't know if there's an easy way to look this up automatically in Python.
A couple ideas were tossed around using "typeof", jQuery ".is" and ".filter" so I thought I would post up a quick perf compare of them. The typeof appears to be the best choice for this. While the others will work, there appears to be a clear performance difference when invoking the jq library for this effort.
database_password: password
would between quotes: " or '.
like so:
database_password: "password"

With MVC you can simply return a file like this:
public ActionResult ExportData()
{
System.IO.FileInfo exportFile = //create your ExportFile
return File(exportFile.FullName, "text/csv", string.Format("Export-{0}.csv", DateTime.Now.ToString("yyyyMMdd-HHmmss")));
}
I realize this was long ago answered but want to suggest an additional approach that avoids the nested try-with-resources double block.
public List<User> getUser(int userId) {
try (Connection con = DriverManager.getConnection(myConnectionURL);
PreparedStatement ps = createPreparedStatement(con, userId);
ResultSet rs = ps.executeQuery()) {
// process the resultset here, all resources will be cleaned up
} catch (SQLException e) {
e.printStackTrace();
}
}
private PreparedStatement createPreparedStatement(Connection con, int userId) throws SQLException {
String sql = "SELECT id, username FROM users WHERE id = ?";
PreparedStatement ps = con.prepareStatement(sql);
ps.setInt(1, userId);
return ps;
}
This method is in BalusC's StringUtil class. his blog
i use it very often and will trim any string of any value:
/**

* @param string The string to be trimmed.
* @param trim The value to trim the given string off.
* @return The trimmed string.
*/
public static String trim(String string, String trim) {
if (string == null) {
return null;
}
if (trim.length() == 0) {
return string;
}
int start = 0;
int end = string.length();
int length = trim.length();
while (start + length <= end && string.substring(
start, start + length).equals(trim)) {
start += length;
}
while (start + length <= end && string.substring(
end - length, end).equals(trim)) {
end -= length;
}
return string.substring(start, end);
}
ex:
trim("1, 2, 3, ", ", ");
Correct on all fronts. Outside of a character class (that's what the "square brackets" are called) the hyphen has no special meaning, and within a character class, you can place a hyphen as the first or last character in the range (e.g. [-a-z]
or [0-9-]
), OR escape it (e.g. [a-z\-0-9]
) in order to add "hyphen" to your class.
It's more common to find a hyphen placed first or last within a character class, but by no means will you be lynched by hordes of furious neckbeards for choosing to escape it instead.
(Actually... my experience has been that a lot of regex is employed by folks who don't fully grok the syntax. In these cases, you'll typically see everything escaped (e.g. [a-z\%\$\#\@\!\-\_]
) simply because the engineer doesn't know what's "special" and what's not... so they "play it safe" and obfuscate the expression with loads of excessive backslashes. You'll be doing yourself, your contemporaries, and your posterity a huge favor by taking the time to really understand regex syntax before using it.)

Without the typedef
word, in C++ the declaration would declare a variable FunctionFunc
of type pointer to function of no arguments, returning void
.
With the typedef
it instead defines FunctionFunc
as a name for that type.
If you're open to out-of-the-DB solution: You could set up a cron job that runs a script that will itself call the procedure.
Had the same issue on windows XP. Resolved. The error was caused due to the system log being full. Control Panel -> Administrative Tools -> Event viewer Right click on application log, clear all events, optionaly save the log. Same process for system log. Restart and it should work.
I recently ran into this problem again. It's been a while since I last worked with submodules and having learned more about git I realized that simply checking out the branch you want to commit on is sufficient. Git will keep the working tree even if you don't stash it.
git checkout existing_branch_name
If you want to work on a new branch this should work for you:
git checkout -b new_branch_name
The checkout will fail if you have conflicts in the working tree, but that should be quite unusual and if it happens you can just stash it, pop it and resolve the conflict.
Compared to the accepted answer, this answer will save you the execution of two commands, that don't really take that long to execute anyway. Therefore I will not accept this answer, unless it miraculously gets more upvotes (or at least close) than the currently accepted answer.

Below are the steps for hiding the action bar permanently:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
.Now replace the parent with any other theme that contains "NoActionBar" in its name.
a. You can also check how a theme looks by switching to the design tab of activity_main.xml and then trying out each theme provided in the theme drop-down list of the UI.
If your MainActivity extends AppCompatActivity, make sure you use an AppCompat theme.
I faced the same issue. I updated my Android studio and used API 25 target as Android 7.1.1 and X86 and everything worked fine. I use Google play services and firebase for my project
I think the easiest way is to use the Tag property in your FormOptions class set the Tag = value you need to pass and after the ShowDialog method read it as
myvalue x=(myvalue)formoptions.Tag;
if exists (SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[MyTable]') )
I don't think you need to deintegrate anymore. I was able to do it with the following command in terminal:
pod install
and it automatically removed the ones that are no longer in the podfile
The size arguments are in pixels. So, to double your example's marker size the fifth argument to the MarkerImage constructor would be:
new google.maps.Size(42,68)
I find it easiest to let the map API figure out the other arguments, unless I need something other than the bottom/center of the image as the anchor. In your case you could do:
var pinIcon = new google.maps.MarkerImage(
"http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + pinColor,
null, /* size is determined at runtime */
null, /* origin is 0,0 */
null, /* anchor is bottom center of the scaled image */
new google.maps.Size(42, 68)
);
As you've said you don't want to set up your own repository, perhaps this will help.
You can use the install-file goal of the maven-install-plugin to install a file to the local repository. If you create a script with a Maven invocation for each file and keep it alongside the jars, you (and anyone else with access) can easily install the jars (and associated pom files) to their local repository.
For example:
mvn install:install-file -Dfile=/usr/jars/foo.jar -DpomFile=/usr/jars/foo.pom
mvn install:install-file -Dfile=/usr/jars/bar.jar -DpomFile=/usr/jars/bar.pom
or just
mvn install:install-file -Dfile=ojdbc14.jar -DgroupId=com.oracle -DartifactId=ojdbc14 -Dversion=10.2.0 -Dpackaging=jar
You can then reference the dependencies as normal in your project.
However your best bet is still to set up an internal remote repository and I'd recommend using Nexus myself. It can run on your development box if needed, and the overhead is minimal.
I would recommend using jQuery with this function:
$(document).ready(function(){
$('#about').addClass('expand');
});
This will add the expand class to an element with id of about when the dom is ready on page load.
Using sortBy...
could help.
$users = User::all()->with('rated')->get()->sortByDesc('rated.rating');
That is how I prevented direct access from URL to my ini files. Paste the following code in .htaccess
file on root. (no need to create extra folder)
<Files ~ "\.ini$">
Order allow,deny
Deny from all
</Files>
my settings.ini
file is on the root, and without this code is accessible www.mydomain.com/settings.ini
How to ignore new files
Globally
Add the path(s) to your file(s) which you would like to ignore to your .gitignore
file (and commit them). These file entries will also apply to others checking out the repository.
Locally
Add the path(s) to your file(s) which you would like to ignore to your .git/info/exclude
file. These file entries will only apply to your local working copy.
How to ignore changed files (temporarily)
In order to ignore changed files to being listed as modified, you can use the following git command:
git update-index --assume-unchanged <file>
To revert that ignorance use the following command:
git update-index --no-assume-unchanged <file>
as first input : <input type="text" style="position:absolute;top:-200px" />
Use ->
when you have a pointer.
Use .
when you have structure (class).
When you want to point attribute that belongs to structure use .
:
structure.attribute
When you want to point to an attribute that has reference to memory by pointer use ->
:
pointer->method;
or same as:
(*pointer).method
I'm surprised nobody has brought up Lua. Lua also uses the 'self' variable however it can be omitted but still used. C++ does the same with 'this'. I don't see any reason to have to declare 'self' in each function but you should still be able to use it just like you can with lua and C++. For a language that prides itself on being brief it's odd that it requires you to declare the self variable.
Use the values
attribute to return the values as a np array and then use [0]
to get the first value:
In [4]:
df.loc[df.Letters=='C','Letters'].values[0]
Out[4]:
'C'
EDIT
I personally prefer to access the columns using subscript operators:
df.loc[df['Letters'] == 'C', 'Letters'].values[0]
This avoids issues where the column names can have spaces or dashes -
which mean that accessing using .

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.
The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.
If this issue is causing serious problems, here are a few things I would suggest:
Revert back to JDK 1.7.0_25 until a fix is added to the JDK.
Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.
Try the JDK early releases as they come out. One of them might fix your problem.
Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.
The <=
in the for statement should be a <
.
BTW, it is possible to do this much more efficiently without using strings, but instead using /10
and %10
of integers.

In the project level build.gradle file, I have replaced this line
classpath 'com.android.tools.build:gradle:3.6.3'

classpath 'com.google.gms:google-services:4.3.3'
After adding both of those lines, and syncing, everything became fine. Hope this will help someone.
You don't want to synchronize on self... Since the self object doesn't exist yet! You end up locking on a temporary id value. You want to ensure that no one else can run class methods ( sharedInstance, alloc, allocWithZone:, etc ), so you need to synchronize on the class object instead:
@implementation MYSingleton
static MYSingleton * sharedInstance = nil;
+( id )sharedInstance {
@synchronized( [ MYSingleton class ] ) {
if( sharedInstance == nil )
sharedInstance = [ [ MYSingleton alloc ] init ];
}
return sharedInstance;
}
+( id )allocWithZone:( NSZone * )zone {
@synchronized( [ MYSingleton class ] ) {
if( sharedInstance == nil )
sharedInstance = [ super allocWithZone:zone ];
}
return sharedInstance;
}
-( id )init {
@synchronized( [ MYSingleton class ] ) {
self = [ super init ];
if( self != nil ) {
// Insert initialization code here
}
return self;
}
}
@end

If you want to do multiple commands, you could use:
for I in `ls *.sql`
do
grep "foo" $I >> foo.log
grep "bar" $I >> bar.log
done
Still better solution could be to follow a design pattern such that the back-button press event gets propagated from active fragment down to host Activity. So, it's like.. if one of the active fragments consume the back-press, the Activity wouldn't get to act upon it, and vice-versa.
One way to do it is to have all your Fragments extend a base fragment that has an abstract 'boolean onBackPressed()' method.
@Override
public boolean onBackPressed() {
if(some_condition)
// Do something
return true; //Back press consumed.
} else {
// Back-press not consumed. Let Activity handle it
return false;
}
}
Keep track of active fragment inside your Activity and inside it's onBackPressed callback write something like this
@Override
public void onBackPressed() {
if(!activeFragment.onBackPressed())
super.onBackPressed();
}
}
This post has this pattern described in detail
This is how I've completed a similar task in Pure JavaScript.
function setup(item){
document.querySelectorAll(".column") /* find all classes named column */
.forEach((item) => { item /* loop through each item */
.addEventListener("click", (event) => { item
/* add event listener for each item found */
.remove(); /* remove self - changed node as needed */
});
});
}
setup();

Here's the example from my code. So I will read a text from 1st line to 3rd line using readLine() and then store to array variable and print into textfield using for-loop :
QFile file("file.txt");
if(!file.open(QIODevice::ReadOnly | QIODevice::Text))

Since curl 7.67.0 (2019-11-06) there is --no-progress-meter
, which does exactly this, and nothing else. From the man page:
--no-progress-meter Option to switch off the progress meter output without muting or otherwise affecting warning and informational messages like -s, --silent does. Note that this is the negated option name documented. You can thus use --progress-meter to enable the progress meter again. See also -v, --verbose and -s, --silent. Added in 7.67.0.
It's available in Ubuntu =20.04 and Debian =11 (Bullseye).
For a bit of history on curl's verbosity options, you can read Daniel Stenberg's blog post.
It's easier with the enumitem package:
\documentclass{article}
\usepackage{enumitem}
\begin{document}
Less space:
\begin{itemize}[noitemsep]
\item foo
\item bar
\item baz
\end{itemize}
Even more compact:
\begin{itemize}[noitemsep,nolistsep]
\item foo
\item bar
\item baz
\end{itemize}
\end{document}
The enumitem package provides a lot of features to customize bullets, numbering and lengths.
The paralist package provides very compact lists: compactitem, compactenum and even lists within paragraphs like inparaenum and inparaitem.

In Java, what's the difference between a keystore and a truststore?
Here's the description from the Java docs at Java Secure Socket Extension (JSSE) Reference Guide. I don't think it tells you anything different from what others have said. But it does provide the official reference.
keystore/truststore
A keystore is a database of key material. Key material is used for a variety of purposes, including authentication and data integrity. Various types of keystores are available, including PKCS12 and Oracle's JKS.
Generally speaking, keystore information can be grouped into two categories: key entries and trusted certificate entries. A key entry consists of an entity's identity and its private key, and can be used for a variety of cryptographic purposes. In contrast, a trusted certificate entry contains only a public key in addition to the entity's identity. Thus, a trusted certificate entry cannot be used where a private key is required, such as in a javax.net.ssl.KeyManager. In the JDK implementation of JKS, a keystore may contain both key entries and trusted certificate entries.
A truststore is a keystore that is used when making decisions about what to trust. If you receive data from an entity that you already trust, and if you can verify that the entity is the one that it claims to be, then you can assume that the data really came from that entity.
An entry should only be added to a truststore if the user trusts that entity. By either generating a key pair or by importing a certificate, the user gives trust to that entry. Any entry in the truststore is considered a trusted entry.
It may be useful to have two different keystore files: one containing just your key entries, and the other containing your trusted certificate entries, including CA certificates. The former contains private information, whereas the latter does not. Using two files instead of a single keystore file provides a cleaner separation of the logical distinction between your own certificates (and corresponding private keys) and others' certificates. To provide more protection for your private keys, store them in a keystore with restricted access, and provide the trusted certificates in a more publicly accessible keystore if needed.

I hope it helps.
Create a dictionary with tuple as the key, and print the keys.
k = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4]]
dict_tuple = {tuple(item): index for index, item in enumerate(k)}
print [list(itm) for itm in dict_tuple.keys()]
# prints [[1, 2], [5, 6, 2], [3], [4]]
You could just write a little script that would try to import all the modules and tell you which ones are failing and which ones are working:
import pip
if __name__ == '__main__':
for package in pip.get_installed_distributions():
pack_string = str(package).split(" ")[0]
try:
if __import__(pack_string.lower()):
print(pack_string + " loaded successfully")
except Exception as e:
print(pack_string + " failed with error code: {}".format(e))
Output:
zope.interface loaded successfully
zope.deprecation loaded successfully
yarg loaded successfully
xlrd loaded successfully
WMI loaded successfully
Werkzeug loaded successfully
WebOb loaded successfully
virtualenv loaded successfully
...
Word of warning this will try to import everything so you'll see things like PyYAML failed with error code: No module named pyyaml
because the actual import name is just yaml. So as long as you know your imports this should do the trick for you.
Looks like you are using maven (src/main/java)
. In this case put the applicationContext.xml
file in the src/main/resources
directory. It will be copied in the classpath directory and you should be able to access it with
@ContextConfiguration("/applicationContext.xml")
From the Spring-Documentation: A plain path, for example "context.xml", will be treated as a classpath resource from the same package in which the test class is defined. A path starting with a slash is treated as a fully qualified classpath location, for example "/org/example/config.xml".
So it's important that you add the slash when referencing the file in the root directory of the classpath.
If you work with the absolute file path you have to use 'file:C:...' (if I understand the documentation correctly).
If you have one condition check instance function in javascript. it's easy to use ternary operator. which will only need one single line to implement. Ex:
private module : string ='';
private page:boolean = false;
async mounted(){
if(this.module=== 'Main')
{
this.page = true;}
else{
this.page = false;
}
}
a function like this with one condition can be written as follow.
this.page = this.module=== 'Main' ?true:false;
condition ? if True : if False
AFAIK, I don't think this is possible with a direct method naming query. You can however use the built in sorting mechanism, using the Sort
class. The repository has a findAll(Sort)
method that you can pass an instance of Sort
to. For example:
import org.springframework.data.domain.Sort;
@Repository
public class StudentServiceImpl implements StudentService {
@Autowired
private StudentDAO studentDao;
@Override
public List<Student> findAll() {
return studentDao.findAll(sortByIdAsc());
}
private Sort sortByIdAsc() {
return new Sort(Sort.Direction.ASC, "id");
}
}
One example of rawQuery - db.rawQuery("select * from table where column = ?",new String[]{"data"});
From my experiences the first few frames that are captured when using:
frame = cvQueryFrame( capture );
Tend to be blank. You may want to wait a short while(about 3 seconds) and then try to capture the image.
Native methods allow you to use code from other languages such as C or C++ in your java code. You use them when java doesn't provide the functionality that you need. For example, if I were writing a program to calculate some equation and create a line graph of it, I would use java, because it is the language I am best in. However, I am also proficient in C. Say in part of my program I need to calculate a really complex equation. I would use a native method for this, because I know some C++ and I know that C++ is much faster than java, so if I wrote my method in C++ it would be quicker. Also, say I want to interact with another program or device. This would also use a native method, because C++ has something called pointers, which would let me do that.
You can unstage files from the index using
git reset HEAD -- path/to/file
Just like git add
, you can unstage files recursively by directory and so forth, so to unstage everything at once, run this from the root directory of your repository:
git reset HEAD -- .
Also, for future reference, the output of git status
will tell you the commands you need to run to move files from one state to another.

I had the same issue. For me it helped to remove the .vs directory in the project folder.
I am having a similar issue now and I believe the problem in my case as well as the original poster is because of the redirect. By default a Response.Redirect causes an exception which immediately bubbles up until it is caught and the redirect is immediately executed, I am guessing that this is preventing the modified cookie collection from being passed down to the client. If you modify your code to use:
Response.Redirect("url", false);
This prevents the exception and seems to allow the cookie to be properly sent back to the client.
EDIT : my bad! With my answer, the icon won't behave as a toggler Actually, it will be shown even when not collapsed... Still searching...
This would work :
<button class="btn btn-primary" type="button" data-toggle="collapse"
data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent"
aria-expanded="false" aria-label="Toggle navigation">
<span>
<i class="fas fa-bars"></i>
</span>
</button>
The trick proposed by my answer is to replace the navbar-toggler
with a classical button class btn
and then, as answered earlier, use an icon font.
Note, that if you keep <button class="navbar-toggler">
, the button will have a "strange" shape.
As stated in this post on github, bootstrap uses some "css trickery", so users don't have to rely on fonts.
So, just don't use the "navbar-toggler"
class on your button if you want to use an icon font.
Cheers.
Try this:

$("#divToReplaceHtml").load('@Url.Action("Action", "Controller")/' + @Model.ID + "?nocache=" + new Date().getTime());
Firstly, with MacOS Catalina, the basic ways to change the ownership of /usr/local are no longer allowed. For example:
$ sudo chown -R "$USER":wheel /usr/local
Password:
chown: /usr/local: Operation not permitted
$ sudo chown -R "$USER" /usr/local
chown: /usr/local: Operation not permitted
$ sudo chown -R $(whoami) /usr/local
chown: /usr/local: Operation not permitted
Hence, the popular answers above cannot be used. Secondly, however, taking a step back, if the main concern is to install or upgrade Homebrew, rather than wanting to change the permissions for /usr/local per se, then it may be overkill (like taking a sledgehammer to hammer a nail) to change the permissions for /usr/local. It affects your whole machine and other software may also be using /usr/local. For example, I have files related to maven and mySQL in /usr/local.
A more precise solution is to follow the instructions to install Homebrew, given at the Homebrew GitHub site, namely
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
which installs Homebrew inside /usr/local without changing ownership of /usr/local itself. Instead, Cellar, Caskroom, Frameworks, Homebrew, etc. are installed inside /usr/local. This seems to be a more elegant, precise solution in my opinion.
I solved this by uncheking the "Use command-line client" option from Subversion settings.
This works with version 1.6 and 1.7 only. See @Vic's answer for SVN version 1.8.
You can use a DOM XML parser to create an XML file using Java. A good example can be found on this site:
try {
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
//root elements
Document doc = docBuilder.newDocument();
Element rootElement = doc.createElement("company");
doc.appendChild(rootElement);
//staff elements
Element staff = doc.createElement("Staff");
rootElement.appendChild(staff);
//set attribute to staff element
Attr attr = doc.createAttribute("id");
attr.setValue("1");
staff.setAttributeNode(attr);
//shorten way
//staff.setAttribute("id", "1");
//firstname elements
Element firstname = doc.createElement("firstname");
firstname.appendChild(doc.createTextNode("yong"));
staff.appendChild(firstname);
//lastname elements
Element lastname = doc.createElement("lastname");
lastname.appendChild(doc.createTextNode("mook kim"));
staff.appendChild(lastname);
//nickname elements
Element nickname = doc.createElement("nickname");
nickname.appendChild(doc.createTextNode("mkyong"));
staff.appendChild(nickname);
//salary elements
Element salary = doc.createElement("salary");
salary.appendChild(doc.createTextNode("100000"));
staff.appendChild(salary);
//write the content into xml file
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("C:\\testing.xml"));
transformer.transform(source, result);
System.out.println("Done");
}catch(ParserConfigurationException pce){
pce.printStackTrace();
}catch(TransformerException tfe){
tfe.printStackTrace();
}
If you do not want to specify a message with your stashed changes, pass the filename after a double-dash.
$ git stash -- filename.ext
If it's an untracked/new file, you will have to stage it first.
However, if you do want to specify a message, use push
.
git stash push -m "describe changes to filename.ext" filename.ext
Both methods work in git versions 2.13+
What happens when you set all of the attributes in one attr()
command like so
$(this).attr({
id : this.id + '_' + new_id,
name: this.name + '_' + new_id,
value: 'test'
});
To get the behavior you want you need to wait for the process to finish before you exit Main()
. To be able to tell when your process is done you need to return a Task
instead of a void
from your function, you should never return void
from a async
function unless you are working with events.
A re-written version of your program that works correctly would be
class Program { static void Main(string[] args) { Debug.WriteLine("Calling DoDownload"); var downloadTask = DoDownloadAsync(); Debug.WriteLine("DoDownload done"); downloadTask.Wait(); //Waits for the background task to complete before finishing. } private static async Task DoDownloadAsync() { WebClient w = new WebClient(); string txt = await w.DownloadStringTaskAsync("http://www.google.com/"); Debug.WriteLine(txt); } }
Because you can not await
in Main()
I had to do the Wait()
function instead. If this was a application that had a SynchronizationContext I would do await downloadTask;
instead and make the function this was being called from async
.
Most answers are a bit more complicated than necessary, or don't provide the exact format requested.
select Format(getdate(), 'MMMM dd yyyy') --returns 'October 01 2020', note the leading zero
select Format(getdate(), 'MMMM d yyyy') --returns the desired format with out the leading zero: 'October 1 2020'
If you want a comma, as you normally would, use:
select Format(getdate(), 'MMMM d, yyyy') --returns 'October 1, 2020'
Note: even though there is only one 'd' for the day, it will become a 2 digit day when needed.
I was confused as I knew VueJS should only contain 1 root element and yet I was still getting this same "template syntax error Component template should contain exactly one root element..." error on an extremely simple component. Turns out I had just mispelled </template> as </tempate> and that was giving me this same error in a few files I copied and pasted. In summary, check your syntax for any mispellings in your component.
You can try:
function onlyAlphabets(e, t) {
return (e.charCode > 64 && e.charCode < 91) || (e.charCode > 96 && e.charCode < 123) || e.charCode == 32;
}
This is how I would start to solve this:
Create a video writer:
import cv2.cv as cv
videowriter = cv.CreateVideoWriter( filename, fourcc, fps, frameSize)
Loop to retrieve[1] and write the frames:
cv.WriteFrame( videowriter, frame )
[1] zenpoy already pointed in the correct direction. You just need to know that you can retrieve images from a webcam or a file :-)
Hopefully I understood the requirements correct.
Use r.URL.Query()
when you appending to existing query, if you are building new set of params use the url.Values
struct like so
package main
import (
"fmt"
"log"
"net/http"
"net/url"
"os"
)
func main() {
req, err := http.NewRequest("GET","http://api.themoviedb.org/3/tv/popular", nil)
if err != nil {
log.Print(err)
os.Exit(1)
}
// if you appending to existing query this works fine
q := req.URL.Query()
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
// or you can create new url.Values struct and encode that like so
q := url.Values{}
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
req.URL.RawQuery = q.Encode()
fmt.Println(req.URL.String())
// Output:
// http://api.themoviedb.org/3/tv/popularanother_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}
This is done with
ANALYZE TABLE table_name;
Read more about it here.
ANALYZE TABLE analyzes and stores the key distribution for a table. During the analysis, the table is locked with a read lock for MyISAM, BDB, and InnoDB. This statement works with MyISAM, BDB, InnoDB, and NDB tables.
FXCop typically prefers OrdinalIgnoreCase
. But your requirements may vary.
For English there is very little difference. It is when you wander into languages that have different written language constructs that this becomes an issue. I am not experienced enough to give you more than that.
OrdinalIgnoreCase
The StringComparer returned by the OrdinalIgnoreCase property treats the characters in the strings to compare as if they were converted to uppercase using the conventions of the invariant culture, and then performs a simple byte comparison that is independent of language. This is most appropriate when comparing strings that are generated programmatically or when comparing case-insensitive resources such as paths and filenames. http://msdn.microsoft.com/en-us/library/system.stringcomparer.ordinalignorecase.aspx
InvariantCultureIgnoreCase
The StringComparer returned by the InvariantCultureIgnoreCase property compares strings in a linguistically relevant manner that ignores case, but it is not suitable for display in any particular culture. Its major application is to order strings in a way that will be identical across cultures. http://msdn.microsoft.com/en-us/library/system.stringcomparer.invariantcultureignorecase.aspx
The invariant culture is the CultureInfo object returned by the InvariantCulture property.
The InvariantCultureIgnoreCase property actually returns an instance of an anonymous class derived from the StringComparer class.
I recommend the setup.py of the Python Packaging User Guide's example project.
The Python Packaging User Guide "aims to be the authoritative resource on how to package, publish and install Python distributions using current tools".
I removed these lines as below :
before :
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar1"
android:layout_width="match_parent"
android:layout_height="@attr/actionBarSize"
android:minHeight="@attr/actionBarSize"
android:layout_alignParentTop="true" >
after :
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar1"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentTop="true" >
Instead of "@attr/actionBarSize" put specific dimens it works for me.
This error also can happen when working with http.request
, probably your request is not finished yet.
Example:
const req = https.request(options, res => {})
And you always need to add this line: req.end()
With this function we will order to finish sending request.
As in documentation is said:
With http.request() one must always call req.end() to signify the end of the request - even if there is no data being written to the request body.
In the case you have a Dictionary of "object" and object can be anything like (double, int, ... or ComplexClass):
Dictionary<string, object> dictSrc { get; set; }
public class ComplexClass : ICloneable
{
private Point3D ...;
private Vector3D ....;
[...]
public object Clone()
{
ComplexClass clone = new ComplexClass();
clone = (ComplexClass)this.MemberwiseClone();
return clone;
}
}
dictSrc["toto"] = new ComplexClass()
dictSrc["tata"] = 12.3
...
dictDest = dictSrc.ToDictionary(entry => entry.Key,
entry => ((entry.Value is ICloneable) ? (entry.Value as ICloneable).Clone() : entry.Value) );
Delete "/var/www/laravel/app/storage/logs/laravel.log"
and try again:
rm storage/logs/laravel.log
In my case, I found out it was division by zero.
Just to complete the answer - on Ubuntu/Mint you can just run:
zcat /usr/share/doc/phpmyadmin/examples/create_tables.sql.gz | mysql
(of course this assumes development environment where your default mysql user is root and you use no password; in other case use | mysql -uuser_name -p
)
If the keystore is PKCS12 type (.pfx
) you have to specify it with -storetype PKCS12
(line breaks added for readability):
keytool -list -v -keystore <path to keystore.pfx> \
-storepass <password> \
-storetype PKCS12
function Do-SendKeys {
param (
$SENDKEYS,
$WINDOWTITLE
)
$wshell = New-Object -ComObject wscript.shell;
IF ($WINDOWTITLE) {$wshell.AppActivate($WINDOWTITLE)}
Sleep 1
IF ($SENDKEYS) {$wshell.SendKeys($SENDKEYS)}
}
Do-SendKeys -WINDOWTITLE Print -SENDKEYS '{TAB}{TAB}'
Do-SendKeys -WINDOWTITLE Print
Do-SendKeys -SENDKEYS '%{f4}'

Use random.choice()
import random
foo = ['a', 'b', 'c', 'd', 'e']
print(random.choice(foo))
For cryptographically secure random choices (e.g. for generating a passphrase from a wordlist) use secrets.choice()
import secrets
foo = ['battery', 'correct', 'horse', 'staple']
print(secrets.choice(foo))
secrets
is new in Python 3.6, on older versions of Python you can use the random.SystemRandom
class:
import random
secure_random = random.SystemRandom()
print(secure_random.choice(foo))
