You could do something like this if you wanted
package main
import "fmt"
type Pair struct {
a, b interface{}
}
func main() {
p1 := Pair{"finished", 42}
p2 := Pair{6.1, "hello"}
fmt.Println("p1=", p1, "p2=", p2)
fmt.Println("p1.b", p1.b)
// But to use the values you'll need a type assertion
s := p1.a.(string) + " now"
fmt.Println("p1.a", s)
}
However I think what you have already is perfectly idiomatic and the struct describes your data perfectly which is a big advantage over using plain tuples.
String.join
Java 8 added a new static method to java.lang.String
which offers a slightly better alternative:
String.join(
CharSequence delimiter ,
CharSequence... elements
)
Using it:
String s = String.join(
System.getProperty("line.separator"),
"First line.",
"Second line.",
"The rest.",
"And the last!"
);
Brian's comments on the tight linkage between language and pattern is to the point,
The missing part of this discussion is the concept of idiom. James O. Coplien's book, "Advanced C++" was a huge influence here. Long before he discovered Christopher Alexander and the Column Without a Name (and you can't talk sensibly about patterns without reading Alexander either), he talked about the importance of mastering idioms in truly learning a language. He used string copy in C as an example, while(*from++ = *to++);
You can see this as a bandaid for a missing language feature (or library feature), but what really matters about it is that it's a larger unit of thought, or of expression, than any of its parts.
That is what patterns, and languages, are trying to do, to allow us to express our intentions more succinctly. The richer the units of thought the more complex the thoughts you can express. Having a rich, shared vocabulary at a range of scales - from system architecture down to bit twiddling - allows us to have more intelligent conversations, and thoughts about what we should be doing.
We can also, as individuals, learn. Which is the entire point of the exercise. We each can understand and use things we would never be able to think of ourselves. Languages, frameworks, libraries, patterns, idioms and so on all have their place in sharing the intellectual wealth.
Sven has shown how to use the class gaussian_kde
from Scipy, but you will notice that it doesn't look quite like what you generated with R. This is because gaussian_kde
tries to infer the bandwidth automatically. You can play with the bandwidth in a way by changing the function covariance_factor
of the gaussian_kde
class. First, here is what you get without changing that function:
However, if I use the following code:
import matplotlib.pyplot as plt
import numpy as np
from scipy.stats import gaussian_kde
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = gaussian_kde(data)
xs = np.linspace(0,8,200)
density.covariance_factor = lambda : .25
density._compute_covariance()
plt.plot(xs,density(xs))
plt.show()
I get
which is pretty close to what you are getting from R. What have I done? gaussian_kde
uses a changable function, covariance_factor
to calculate its bandwidth. Before changing the function, the value returned by covariance_factor for this data was about .5. Lowering this lowered the bandwidth. I had to call _compute_covariance
after changing that function so that all of the factors would be calculated correctly. It isn't an exact correspondence with the bw parameter from R, but hopefully it helps you get in the right direction.
Don't use spaces...

Unfortunately, there is not a direct way to do this with a single formula. However, there is a fairly simple workaround that exists.
On the Excel Ribbon, go to "Formulas" and click on "Name Manager". Select "New" and then enter "CellColor" as the "Name". Jump down to the "Refers to" part and enter the following:
=GET.CELL(63,OFFSET(INDIRECT("RC",FALSE),1,1))
Hit OK then close the "Name Manager" window.
Now, in cell A1 enter the following:
=IF(CellColor=3,"FQS",IF(CellColor=6,"SM",""))
This will return FQS for red and SM for yellow. For any other color the cell will remain blank.
***If the value in A1 doesn't update, hit 'F9' on your keyboard to force Excel to update the calculations at any point (or if the color in B2 ever changes).
Below is a reference for a list of cell fill colors (there are 56 available) if you ever want to expand things: http://www.smixe.com/excel-color-pallette.html
Cheers.
::Edit::
The formula used in Name Manager can be further simplified if it helps your understanding of how it works (the version that I included above is a lot more flexible and is easier to use in checking multiple cell references when copied around as it uses its own cell address as a reference point instead of specifically targeting cell B2).
Either way, if you'd like to simplify things, you can use this formula in Name Manager instead:
=GET.CELL(63,Sheet1!B2)

With xampp I think you need to use the full path at the command line, something like this, perhaps:

Adding an approach to this old question just for the fun of it:
$ cat input.file # file containing input that needs to be processed
a;b;c;d;e
1;2;3;4;5
no delimiter here
124;adsf;15454
foo;bar;is;null;info
$ cat tmp.sh # showing off the script to do the job
#!/bin/bash
delim=';'
while read -r line; do
while [[ "$line" =~ "$delim" ]]; do
line=$(cut -d"$delim" -f 2- <<<"$line")
done
echo "$line"
done < input.file
$ ./tmp.sh # output of above script/processed input file
e
5
no delimiter here
15454
info
Besides bash, only cut is used. Well, and echo, I guess.
For me, ensuring that I had:
#include <iostream>
#include<string>
using namespace std;
in my file made something like to_string(12345)
work.
After failing with cleaning the Credentials from the Manager and clearing the VS cache, consider to repair Visual Studio from the Visual Studio Installer (VS2017). I personally found no other solution working.
I've seen occasional problems with Eclipse forgetting that built-in classes (including Object
and String
) exist. The way I've resolved them is to:
This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.
This worked for me. With the method mentioned here I was able to draw polylines on Google Maps V2. I drew a new line whenever the user location got changed, so the the polyline looks like the path followed by user on map.

For me when trying to open a link :
Uri uri = Uri.parse("https://www.facebook.com/abc/");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
I got the same error android.content.ActivityNotFoundException: No Activity found to handle Intent
The problem was because i didnt have any app that can open URLs (i.e. browsers) installed in my phone. So after Installing a browser the problem was solved.
*Lesson : Make sure there is at least one app which handles the intent you are calling *
You can do this programmatically using a VBA macro. You can make the sheet hidden or very hidden:
Sub HideSheet()
Dim sheet As Worksheet
Set sheet = ActiveSheet
' this hides the sheet but users will be able
' to unhide it using the Excel UI
sheet.Visible = xlSheetHidden
' this hides the sheet so that it can only be made visible using VBA
sheet.Visible = xlSheetVeryHidden
End Sub
You can use the row_number()
function for this.
INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
row_number() over (order by (select NULL))
FROM PM_Ingrediants
WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
)
If you want to start with the maximum already in the table then do:
INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
FROM PM_Ingrediants cross join
(select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
)
Finally, you can just make the sequence
column an auto-incrementing identity column. This saves the need to increment it each time:
create table PM_Ingrediants_Arrangement_Temp ( . . .
sequence int identity(1, 1) -- and might consider making this a primary key too
. . .
)
Every derived table (AKA sub-query) must indeed have an alias. I.e. each query in brackets must be given an alias (AS whatever
), which can the be used to refer to it in the rest of the outer query.
SELECT ID FROM (
SELECT ID, msisdn FROM (
SELECT * FROM TT2
) AS T
) AS T
In your case, of course, the entire query could be replaced with:
SELECT ID FROM TT2
key 13 keycode is for ENTER key.
I used a combination of the above because my app works in the browser as well as on device. The problem with browser is it won't let you close the window from a script unless your app was opened by a script (like browsersync).
if (typeof cordova !== 'undefined') {
if (navigator.app) {
navigator.app.exitApp();
}
else if (navigator.device) {
navigator.device.exitApp();
}
} else {
window.close();
$timeout(function () {
self.showCloseMessage = true; //since the browser can't be closed (otherwise this line would never run), ask the user to close the window
});
}
A histogram is a poor-man's density estimate. Note that in your call to hist()
using default arguments, you get frequencies not probabilities -- add ,prob=TRUE
to the call if you want probabilities.
As for the log axis problem, don't use 'x' if you do not want the x-axis transformed:
plot(mydata_hist$count, log="y", type='h', lwd=10, lend=2)
gets you bars on a log-y scale -- the look-and-feel is still a little different but can probably be tweaked.
Lastly, you can also do hist(log(x), ...)
to get a histogram of the log of your data.
You can use
change config to cookie & type your password in ' ' in password like bellow
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'your password';
Then save & type on browser localhost/phpmyadmin/
Enter your given password & enjoy
If you close the main Activity using Activity.finish()
, I think it will close all the activities.
MAybe you can override the default function, and implement it in a static way, I'm not sure
And it's unlikely too -- EOT is a fairly restrictive format that is supported only by IE. Both Safari 3.1 and Firefox 3.1 (well the current alpha) and possibly Opera 9.6 support true type font (ttf) embedding, and at least Safari supports SVG fonts through the same mechanism. A list apart had a good discussion about this a while back.
The following regex will work for both:
text = text.replaceAll("('|\")", "\\\\$1");
Basically BindingResult
is an interface which dictates how the object that stores the result of validation should store and retrieve the result of the validation(errors, attempt to bind to disallowed fields etc)
From Spring MVC Form Validation with Annotations Tutorial:
[
BindingResult
] is Spring’s object that holds the result of the validation and binding and contains errors that may have occurred. TheBindingResult
must come right after the model object that is validated or else Spring will fail to validate the object and throw an exception.When Spring sees
@Valid
, it tries to find the validator for the object being validated. Spring automatically picks up validation annotations if you have “annotation-driven” enabled. Spring then invokes the validator and puts any errors in theBindingResult
and adds the BindingResult to the view model.
I suggest that you add
#!/usr/bin/env python
instead of #!/usr/bin/python
at the top of the file. The reason for this is that the python installation may be in different folders in different distros or different computers. By using env
you make sure that the system finds python and delegates the script's execution to it.
As said before to make the script executable, something like:
chmod u+x name_of_script.py
should do.
Putting the call to mysql_insert_id()
inside a transaction, should do it:
mysql_query('BEGIN');
// Whatever code that does the insert here.
$id = mysql_insert_id();
mysql_query('COMMIT');

The answer below is taken from Reading from Console: JAVA Scanner vs BufferedReader
When read an input from console, there are two options exists to achieve that. First using Scanner
, another using BufferedReader
. Both of them have different characteristics. It means differences how to use it.
Scanner treated given input as token. BufferedReader just read line by line given input as string. Scanner it self provide parsing capabilities just like nextInt(), nextFloat().
But, what is others differences between?
Scanner come with since JDK version 1.5 higher.
When should use Scanner, or Buffered Reader?
Look at the main differences between both of them, one using tokenized, others using stream line. When you need parsing capabilities, use Scanner instead. But, i am more comfortable with BufferedReader. When you need to read from a File, use BufferedReader, because it’s use buffer when read a file. Or you can use BufferedReader as input to Scanner.
After Redis 2.6, the result of INFO command are splitted by sections. In the "keyspace" section, there are "keys" and "expired keys" fields to tell how many keys are there.
You can use a vector. Instead of worry about different screen sizes you only need to create an .svg file and import it to your project using Vector Asset Studio.
jQuery provides a method called "siblings()" which helps us to return all sibling elements of the selected element. For example, if you want to apply CSS to the sibling selectors, you can use this method. Below is an example which illustrates this. You can try this example and play with it to learn how it works.
$("p").siblings("h4").css({"color": "red", "border": "2px solid red"});
For capital letters:
i=67

You can use ng-show on every div element in the loop. Is this what you've wanted: http://jsfiddle.net/pGwRu/2/ ?
<div class="from" ng-show="message.from">From: {{message.from.name}}</div>
Recently ran into this when upgrading from 2.3 to 3.1; our jQuery animations (slideDown) broke because we were putting hide on the elements in the page template. We went the route of creating name-spaced versions of Bootstrap classes that now carry the ugly !important rule.
.rb-hide { display: none; }
.rb-pull-left { float: left; }
etc...
So, the answers here are all a bit incomplete. The use of a '%20' to encode a space in URLs is explicitly defined in RFC3986, which defines how a URI is built. There is no mention in this specification of using a '+' for encoding spaces - if you go solely by this specification, a space must be encoded as '%20'.
The mention of using '+' for encoding spaces comes from the various incarnations of the HTML specification - specifically in the section describing content type 'application/x-www-form-urlencoded'. This is used for posting form data.
Now, the HTML 2.0 Specification (RFC1866) explicitly said, in section 8.2.2, that the Query part of a GET request's URL string should be encoded as 'application/x-www-form-urlencoded'. This, in theory, suggests that it's legal to use a '+' in the URL in the query string (after the '?').
But... does it really? Remember, HTML is itself a content specification, and URLs with query strings can be used with content other than HTML. Further, while the later versions of the HTML spec continue to define '+' as legal in 'application/x-www-form-urlencoded' content, they completely omit the part saying that GET request query strings are defined as that type. There is, in fact, no mention whatsoever about the query string encoding in anything after the HTML 2.0 spec.
Which leaves us with the question - is it valid? Certainly there's a LOT of legacy code which supports '+' in query strings, and a lot of code which generates it as well. So odds are good you won't break if you use '+'. (And, in fact, I did all the research on this recently because I discovered a major site which failed to accept '%20' in a GET query as a space. They actually failed to decode ANY percent encoded character. So the service you're using may be relevant as well.)
But from a pure reading of the specifications, without the language from the HTML 2.0 specification carried over into later versions, URLs are covered entirely by RFC3986, which means spaces ought to be converted to '%20'. And definitely that should be the case if you are requesting anything other than an HTML document.
It is possible, they are not connected in InterfaceBuilder.
Text colour(colorWithRed:(188/255) green:(149/255) blue:(88/255))
is correct, may be mistake in connections,
backgroundcolor is used for the background colour of label and textcolor is used for property textcolor.
Testing $?
is an anti-pattern.

I use the library Globalize (from Microsoft):
It's a great project to localize numbers, currencies and dates and to have them automatically formatted the right way according to the user locale! ...and despite it should be a jQuery extension, it's currently a 100% independent library. I suggest you all to try it out! :)
For info, if you are binding to a class, you can do this in your type via DisplayNameAttribute
:
[DisplayName("Access key")]
public string AccessKey { get {...} set {...} }
Now the header-text on auto-generated columns will be "Access key".
Which version of .NET are you using? If it's .NET 3.5, I'd just call ToArray()
and be done with it.
If you only have a non-generic IEnumerable, do something like this:
IEnumerable query = ...;
MyEntityType[] array = query.Cast<MyEntityType>().ToArray();
If you don't know the type within that method but the method's callers do know it, make the method generic and try this:
public static void T[] PerformQuery<T>()
{
IEnumerable query = ...;
T[] array = query.Cast<T>().ToArray();
return array;
}
In my case (reading a date from a MySQL db in a Lumen 5.1 project) the only solution that worked is using Carbon to set timezone of variables:
$carbonDate = new Carbon($dateFromDBInUTC);
$carbonDate->timezone = 'America/New_York';
return $carbonDate->toDayDateTimeString(); // or $carbonDate->toDateTimeString() for ISO format
Using DB_TIMEZONE=-05:00
in the .env
file almost worked but does not handle DST changes.
Using the APP_TIMEZONE=America/New_York
in the .env
file had no effect on a timezone value retrieved in a Lumen 5.1 webapp from a MySQL database, but it works in Lavarel 5.1.
Also Lumen didn't read at all the [lumen_project]/config/app.php
file that I created (it didn't complain when I put a syntax error there).
Using date_default_timezone_set
didn't work either.
I decided to compact everything I learned into one file. There's a lot to take in here especially compared to before RC5. Note that this source file includes the AppModule and AppComponent.

Here's another way: this adds a circle to the current axes, plot or image or whatever :
from matplotlib.patches import Circle # $matplotlib/patches.py
def circle( xy, radius, color="lightsteelblue", facecolor="none", alpha=1, ax=None ):
""" add a circle to ax= or current axes
"""
# from .../pylab_examples/ellipse_demo.py
e = Circle( xy=xy, radius=radius )
if ax is None:
ax = pl.gca() # ax = subplot( 1,1,1 )
ax.add_artist(e)
e.set_clip_box(ax.bbox)
e.set_edgecolor( color )
e.set_facecolor( facecolor ) # "none" not None
e.set_alpha( alpha )
(The circles in the picture get squashed to ellipses because imshow aspect="auto"
).

I needed to extract text between tags and aggregate (by concat) the text including in innner tags.
/node()
did the job, while /text()
made half job
/text()
only returned text not included in inner tags, because inner tags are not "text nodes". You may think, "just extract text included in the inner tags in an additional xpath", however, it becomes challenging to sort the text in this original order because you dont know where to place the aggregated text from the inner tags!because you dont know where to place the aggregated text from the inner nodes.
Finally, /node()
did exactly what I wanted, because it gets the text from inner tags too.
You are looking for serialize(). Here is an example:
$array = array('foo', 'bar');
//Array to String
$string = serialize($array);
//String to array
$array = unserialize($string);
public static int round(double d) {
if (d > 0) {
return (int) (d + 0.5);
} else {
return (int) (d - 0.5);
}
}
This walk through your multidimensional object composed of sub-objects, arrays and string and apply a custom function
export const iterate = (object, func) => {
const entries = Object.entries(object).map(([key, value]) =>
Array.isArray(value)
? [key, value.map(e => iterate(e, func))]
: typeof value === 'object'
? [key, iterate(value, func)]
: [key, func(value)]
);
return Object.fromEntries(entries);
};
usage:
const r = iterate(data, e=>'converted_'+e);
console.log(r);
RxJS 6
When upgrading to version 6 of the RxJS
library and not using the rxjs-compat
package the following code
import 'rxjs/add/observable/of';
// ...
return Observable.of(res);
has to be changed into
import { of } from 'rxjs';
// ...
return of(res);
I got one good solution. Here I have attached it as the image below. So try it. It may be helpful to you...!
df.groupby('Company Name').agg({'Organisation name':'count','Amount':'sum'})\
.apply(lambda x: x.sort_values(['count','sum'], ascending=False))
Really fast, really easy:
srand(time(NULL)); // Seed the time
int finalNum = rand()%(max-min+1)+min; // Generate the number, assign to variable.
And that is it. However, this is biased towards the lower end, but if you are using C++ TR1/C++11 you can do it using the random
header to avoid that bias like so:
#include <random>
std::mt19937 rng(seed);
std::uniform_int_distribution<int> gen(min, max); // uniform, unbiased
int r = gen(rng);
But you can also remove the bias in normal C++ like this:
int rangeRandomAlg2 (int min, int max){
int n = max - min + 1;
int remainder = RAND_MAX % n;
int x;
do{
x = rand();
}while (x >= RAND_MAX - remainder);
return min + x % n;
}
and that was gotten from this post.
In case someone is interested in dplyr
solution, it's very intuitive:

Zoltan answer will allow user entry "(99) 9999" and then leave the field incomplete
$("#phone").mask("(99) 9999-9999?9");
$("#phone").on("blur", function() {
var last = $(this).val().substr( $(this).val().indexOf("-") + 1 );
if( last.length == 5 ) {
var move = $(this).val().substr( $(this).val().indexOf("-") + 1, 1 );
var lastfour = last.substr(1,4);
var first = $(this).val().substr( 0, 9 );
$(this).val( first + move + '-' + lastfour );
}
});?
You want rows where that condition is true so you need a comma:
data[data$Ozone > 14, ]
Go to your desired perspective. Go to 'Window->show view' menu.
If you see logcat there, click it and you are done.

secure - This attribute tells the browser to only send the cookie if the request is being sent over a secure channel such as HTTPS. This will help protect the cookie from being passed over unencrypted requests. If the application can be accessed over both HTTP and HTTPS, then there is the potential that the cookie can be sent in clear text.
Java 8+ has computeIfAbsent
examList.computeIfAbsent(map.get(id), k -> new ArrayList<>());
map.get(id).add(value);
I created a generic solution out of the existing answers which can be reused for any table:
CREATE OR REPLACE FUNCTION create_if_not_exists (table_name text, create_stmt text)
RETURNS text AS
$_$
BEGIN
IF EXISTS (
SELECT *
FROM pg_catalog.pg_tables
WHERE tablename = table_name
) THEN
RETURN 'TABLE ' || '''' || table_name || '''' || ' ALREADY EXISTS';
ELSE
EXECUTE create_stmt;
RETURN 'CREATED';
END IF;
END;
$_$ LANGUAGE plpgsql;
Usage:
select create_if_not_exists('my_table', 'CREATE TABLE my_table (id integer NOT NULL);');
It could be simplified further to take just one parameter if one would extract the table name out of the query parameter. Also I left out the schemas.
-To compare only the date part, you can do:
var result = db.query($"SELECT * FROM table WHERE date >= '{fromDate.ToString("yyyy-MM-dd")}' and date <= '{toDate.ToString("yyyy-MM-dd"}'");
now := []byte{0xFF,0xFF,0xFF,0xFF}
nowBuffer := bytes.NewReader(now)
var nowVar uint32
binary.Read(nowBuffer,binary.BigEndian,&nowVar)
fmt.Println(nowVar)

I had the same problem. At least I could solve it with this:
sudo yum install gcc gcc-c++
Hope it solves your problem too.
Your solution is correct, but there is some redundancy in your regex.
The similar result can also be obtained from the following regex:
^([A-Z]{3})$
The {3}
indicates that the [A-Z]
must appear exactly 3 times.
You can also use the boar
package to run your notebook within a python code.
from boar.running import run_notebook
outputs = run_notebook("nb.ipynb")
If you update your notebook, you won't have to convert it again to a python file.

This tutorial on networking physics simulations contains a C++ class in the sample code for simulating latency and packet loss in a UDP connection and may be of guidance. See the public latency and packetLoss variables of the Connection class found in the Connection.h file of the downloadable source code.
If your data has a regular structure you can read a file in line by line and populate your favorite container. For example:
Let's say your data has 3 variables: x, y, i.
A file contains n of these data, each variable on its own line (3 lines per record). Here are two records:
384
198
0
255
444
2
Here's how you read your file data into a list. (Reading from text, so cast accordingly.)
data = []
try:
with open(dataFilename, "r") as file:
# read data until end of file
x = file.readline()
while x != "":
x = int(x.strip()) # remove \n, cast as int
y = file.readline()
y = int(y.strip())
i = file.readline()
i = int(i.strip())
data.append([x,y,i])
x = file.readline()
except FileNotFoundError as e:
print("File not found:", e)
return(data)
For a user control named myPartial.ascx located at Views/Account folder write like this:
<%Html.RenderPartial("~/Views/Account/myPartial.ascx");%>
You can use a simple approach...
$('YourDataTableID').dataTable()._fnAjaxUpdate();
It will refresh the data by making an ajax request with the same parameters. Very simple.
Add the following values to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion Add: DWORD ForceLog set value to 1 DWORD LogFailures set value to 1 DWORD LogResourceBinds set value to 1 DWORD EnableLog set value to 1 String LogPath set value to folder for logs (e.g. C:\FusionLog\)
Make sure you include the backslash after the folder name and that the Folder exists.
You need to restart the program that you're running to force it to read those registry settings.
By the way, don't forget to turn off fusion logging when not needed.
My approach is using the attributes collection to add HTML data- attributes from code behind. This is more inline with jquery and client side scripting.
// This would likely be done with findControl in your grid OnItemCreated handler
LinkButton targetBtn = new LinkButton();
// Add attributes
targetBtn.Attributes.Add("data-{your data name here}", value.ToString() );
targetBtn.Attributes.Add("data-{your data name 2 here}", value2.ToString() );
Then retrieve the values through the attribute collection
string val = targetBtn.Attributes["data-{your data name here}"].ToString();
I was struggling with the problem as well.
After I typed $ eval 'ssh-agent -s' followed by $ssh-add ~/.ssh/id_rsa
I got the same complain: "Could not open a connection to your authentication agent". Then I realize there are two different kind of quotation on my computer's keyboard. So I tried the one at the same position as "~":
$ eval ssh-agent -s
$ ssh-add ~/.ssh/id_rsa
And bang it worked.

set @Role = 'Beta'
select Roles

where Roles.exist('/root/role/text()[. = sql:variable("@Role")]') = 1
If you want the query to work as where col like '%Beta%'
you can use contains
declare @T table(Roles xml)
insert into @T values
('<root>
<role>Alpha</role>
<role>Beta</role>
<role>Gamma</role>

You are trying to decode an object that is already decoded. You have a str
, there is no need to decode from UTF-8 anymore.
Simply drop the .decode('utf-8')
part:
header_data = data[1][0][1]
As for your fetch()
call, you are explicitly asking for just the first message. Use a range if you want to retrieve more messages. See the documentation:
The message_set options to commands below is a string specifying one or more messages to be acted upon. It may be a simple message number (
'1'
), a range of message numbers ('2:4'
), or a group of non-contiguous ranges separated by commas ('1:3,6:9'
). A range can contain an asterisk to indicate an infinite upper bound ('3:*'
).
I always use this one (it's easy and fast) :
#include <iostream>
using namespace std;
int i,j;
bool b[101];
int main( )
{
for(i=2;i<101;i++){
b[i]=true;
}
for(i=1;i<101;i++){
if(b[i]){
cout<<i<<" ";
for(j=i*2;j<101;j+=i) b[j]=false;
}
}
}
Here is output of this code: 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
If you were asking how to remove the empty strings, you can do it like this (where l
is an ArrayList<String>
) - this removes all null
references and strings of length 0:
Iterator<String> i = l.iterator();
while (i.hasNext())
{
String s = i.next();
if (s == null || s.isEmpty())
{
i.remove();
}
}
Don't confuse an ArrayList
with arrays, an ArrayList
is a dynamic data-structure that resizes according to it's contents. If you use the code above, you don't have to do anything to get the result as you've described it -if your ArrayList
was ["","Hi","","How","are","you"], after removing as above, it's going to be exactly what you need - ["Hi","How","are","you"]
.
However, if you must have a 'sanitized' copy of the original list (while leaving the original as it is) and by 'store it back' you meant 'make a copy', then krmby's code in the other answer will serve you just fine.
As well as @Pablo's answer, for newer versions you can also use the asp-page-handler tag helper.
In the page:
<button asp-page-handler="Action1" type="submit">Action 1</button>
<button asp-page-handler="Action2" type="submit">Action 2</button>
then in the controller:
public async Task OnPostAction1Async() {...}
public async Task OnPostAction2Async() {...}
SET
SET @var_name = value
OR
SET @var := value
both operators = and := are accepted
SELECT
SELECT col1, @var_name := col2 from tb_name WHERE "conditon";
if multiple record sets found only the last value in col2 is keep (override);
SELECT col1, col2 INTO @var_name, col3 FROM .....
in this case the result of select is not containing col2 values
Ex both methods used
-- TRIGGER_BEFORE_INSERT --- setting a column value from calculations
...
SELECT count(*) INTO @NR FROM a_table WHERE a_condition;
SET NEW.ord_col = IFNULL( @NR, 0 ) + 1;
...
So, the concept of a "wildcard" in Regular Expressions works a bit differently. In order to match "any character" you would use "." The "*" modifier means, match any number of times.
From ggplot 2.2.0
labels can easily be stacked by using position = position_stack(vjust = 0.5)
in geom_text
.
ggplot(Data, aes(x = Year, y = Frequency, fill = Category, label = Frequency)) +
geom_bar(stat = "identity") +
geom_text(size = 3, position = position_stack(vjust = 0.5))
Also note that "position_stack()
and position_fill()
now stack values in the reverse order of the grouping, which makes the default stack order match the legend."
Answer valid for older versions of ggplot
:
Here is one approach, which calculates the midpoints of the bars.
library(ggplot2)
library(plyr)
# calculate midpoints of bars (simplified using comment by @DWin)
Data <- ddply(Data, .(Year),
transform, pos = cumsum(Frequency) - (0.5 * Frequency)
)
# library(dplyr) ## If using dplyr...
# Data <- group_by(Data,Year) %>%
# mutate(pos = cumsum(Frequency) - (0.5 * Frequency))
# plot bars and add text
p <- ggplot(Data, aes(x = Year, y = Frequency)) +
geom_bar(aes(fill = Category), stat="identity") +
geom_text(aes(label = Frequency, y = pos), size = 3)
/^[a-zA-Z]+$/
Off the top of my head.
Edit:
Or if you don't like the weird looking literal syntax you can do it like this
new RegExp("^[a-zA-Z]+$");
ng-bind
is also safer because it represents html
as a string.
So for example, '<script on*=maliciousCode()></script>'
will be displayed as a string and not be executed.
Use orderBy:
df.orderBy('column_name', ascending=False)
Complete answer:
group_by_dataframe.count().filter("`count` >= 10").orderBy('count', ascending=False)

Your root
account, and this statement applies to any account, may only have been added with localhost access (which is recommended).
You can check this with:
SELECT host FROM mysql.user WHERE User = 'root';
If you only see results with localhost
and 127.0.0.1
, you cannot connect from an external source. If you see other IP addresses, but not the one you're connecting from - that's also an indication.
You will need to add the IP address of each system that you want to grant access to, and then grant privileges:
CREATE USER 'root'@'ip_address' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'ip_address';
If you see %
, well then, there's another problem altogether as that is "any remote source". If however you do want any/all systems to connect via root, use the %
wildcard to grant access:
CREATE USER 'root'@'%' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
Finally, reload the permissions, and you should be able to have remote access:
FLUSH PRIVILEGES;
Only solution that works was create a new conda env with the name you want (you will, unfortunately, delete the old one to keep the name). Then create a new env with a new python version and re-run your install.sh
script with the conda/pip installs (or the yaml file or whatever you use to keep your requirements):
conda remove --name original_name --all
conda create --name original_name python=3.8
sh install.sh # or whatever you usually do to install dependencies
doing conda install python=3.8
doesn't work for me. Also, why do you want 3.6? Move forward with the word ;)
If you want to update the conda version of your previous env what you can also do is the following (more complicated than it should be because you cannot rename envs in conda):
conda create --name temporary_env_name --clone original_env_name
conda deactivate
conda remove --name original_env_name --all # or its alias: `conda env remove --name original_env_name`
conda create --name original_env_name python=3.8 --clone temporary_env_name
Per HTML syntax, and even HTML5, the following are all valid options:
<option value=""asd">test</option>
<option value=""asd">test</option>
<option value='"asd'>test</option>
<option value='"asd'>test</option>
<option value='"asd'>test</option>
<option value="asd>test</option>
<option value="asd>test</option>
Note that if you are using XML syntax the quotes (single or double) are required.
Here is how you can scale it easily.
This works in 2.x with the Simulator and the iPhone.
UIImage *thumbnail = [originalImage _imageScaledToSize:CGSizeMake(40.0, 40.0) interpolationQuality:1];
Since functions in Javascript can be called with any number of arguments, and the document doesn't place any restriction on the onFulfilled()
method's arguments besides the below clause, I think that you can pass multiple arguments to the onFulfilled()
method as long as the promise's value is the first argument.
2.2.2.1 it must be called after promise is fulfilled, with promise’s value as its first argument.
All the other codes I've tested didn't work good due to the fact that the user could still place the caret/cursor wherever in the middle of the string (ex.: 12|3.00 - where | is the cursor). My solution always puts the cursor in the end of the string whenever the touch occurs on the EditText.
The ultimate solution is:
// For a EditText like:
<EditText
android:id="@+id/EditTextAmount"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:hint="@string/amount"
android:layout_weight="1"
android:text="@string/zero_value"
android:inputType="text|numberDecimal"
android:maxLength="13"/>
@string/amount="0.00" @string/zero_value="0.00"
// Create a Static boolean flag
private static boolean returnNext;
// Set caret/cursor to the end on focus change
EditTextAmount.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View editText, boolean hasFocus) {
if(hasFocus){
((EditText) editText).setSelection(((EditText) editText).getText().length());
}
}
});
// Create a touch listener and put caret to the end (no matter where the user touched in the middle of the string)
EditTextAmount.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View editText, MotionEvent event) {
((EditText) editText).onTouchEvent(event);
((EditText) editText).setSelection(((EditText) editText).getText().length());
return true;
}
});
// Implement a Currency Mask with addTextChangedListener
EditTextAmount.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
String input = s.toString();
String output = new String();
String buffer = new String();
String decimals = new String();
String numbers = Integer.toString(Integer.parseInt(input.replaceAll("[^0-9]", "")));
if(returnNext){
returnNext = false;
return;
}
returnNext = true;
if (numbers.equals("0")){
output += "0.00";
}
else if (numbers.length() <= 2){
output += "0." + String.format("%02d", Integer.parseInt(numbers));
}
else if(numbers.length() >= 3){
decimals = numbers.substring(numbers.length() - 2);
int commaCounter = 0;
for(int i=numbers.length()-3; i>=0; i--){
if(commaCounter == 3){
buffer += ",";
commaCounter = 0;
}
buffer += numbers.charAt(i);
commaCounter++;
}
output = new StringBuilder(buffer).reverse().toString() + "." + decimals;
}
EditTextAmount.setText(output);
EditTextAmount.setSelection(EditTextAmount.getText().length());
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
/*String input = s.toString();
if(input.equals("0.0")){
EditTextAmount.setText("0.00");
EditTextAmount.setSelection(EditTextAmount.getText().length());
return;
}*/
}
@Override
public void afterTextChanged(Editable s) {
}
});
Hope it helps!
Create a Game model which extends Eloquent and use this:
Game::take(30)->skip(30)->get();
take()
here will get 30 records and skip()
here will offset to 30 records.
In recent Laravel versions you can also use:
Game::limit(30)->offset(30)->get();
==========Advise==========
@martin clayton Answer is correct, But this is an advise only.
Please avoid the use of ambiguous variable in the stored procedure.
Example :
SELECT Id, dateCreated
INTO id, datecreated
FROM products
WHERE pName = iName
The above example will cause an error (null value error)
Example give below is correct. I hope this make sense.
Example :
SELECT Id, dateCreated
INTO val_id, val_datecreated
FROM products
WHERE pName = iName
You can also make them unambiguous by referencing the table, like:
[ Credit : maganap ]
SELECT p.Id, p.dateCreated INTO id, datecreated FROM products p
WHERE pName = iName
You must have use correct signature for input parameter *IN is missing in the below code.
CREATE PROCEDURE my_sqrt(IN input_number INT, OUT out_number FLOAT)
General purpose normalisation function to format any timestamp from any timezone to other.
Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')
/**
* Convert Datetime from any given olsonzone to other.
* @return datetime in user specified format
*/
function datetimeconv($datetime, $from, $to)
{
try {
if ($from['localeFormat'] != 'Y-m-d H:i:s') {
$datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
}
$datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
$datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
return $datetime->format($to['localeFormat']);
} catch (\Exception $e) {
return null;
}
}
Usage:
$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta']; $to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC']; datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"
well, using the Macro record, and doing it manually, I ended up with this code .. which seems to work .. (although it's not a one liner like yours ;)
lrow = Selection.Row()
Rows(lrow).Select
Selection.Copy
Rows(lrow + 1).Select
Selection.Insert Shift:=xlDown
Application.CutCopyMode = False
Selection.ClearContents
(I put the ClearContents in there because you indicated you wanted format, and I'm assuming you didn't want the data ;) )
This should help :-
UITableViewCell* cell = (UITableViewCell*)[sender superview];
NSIndexPath* indexPath = [myTableView indexPathForCell:cell];
Here sender is the UIButton instance that is sending the event. myTableView is the UITableView instance you're dealing with.
Just get the cell reference right and all the work is done.
You may need to remove the buttons from cell's contentView & add them directly to UITableViewCell instance as it's subview.
Or
You can formulate a tag naming scheme for different UIButtons in cell.contentView. Using this tag, later you can know the row & section information as needed.
I found that the cleanest way to do this is to create a custom TwigExtension and override its getGlobals()
method. Rather than using $_SESSION
, it's also better to use Symfony's Session
class since it handles automatically starting/stopping the session.
I've got the following extension in /src/AppBundle/Twig/AppExtension.php:
<?php
namespace AppBundle\Twig;
use Symfony\Component\HttpFoundation\Session\Session;
class AppExtension extends \Twig_Extension {
public function getGlobals() {
$session = new Session();
return array(
'session' => $session->all(),
);
}
public function getName() {
return 'app_extension';
}
}
Then add this in /app/config/services.yml:
services:
app.twig_extension:
class: AppBundle\Twig\AppExtension
public: false
tags:
- { name: twig.extension }
Then the session can be accessed from any view using:
{{ session.my_variable }}
Another thing that can cause this error is having NuGet packages that have been built with a newer version of .NET.
The original error:
frmTestPlanSelector.cs(11,7): error CS0246: The type or namespace name 'DatabaseManager'
could not be found (are you missing a using directive or an assembly reference?)
Further up in the log I found this:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1605,5): warning MSB3275: The primary reference "[redacted]\DatabaseManager\bin\Release\DatabaseManager.dll" could not be resolved because it has an indirect dependency on the assembly "System.Data.SQLite, Version=1.0.94.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" which was built against the ".NETFramework,Version=v4.5" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0".
The solution was to re-install the NuGet packages:
Shorter than accepted answer, same idea:
(SELECT TRIM('2016-01-05' + INTERVAL a + b DAY) date
FROM
(SELECT 0 a UNION SELECT 1 a UNION SELECT 2 UNION SELECT 3
UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7
UNION SELECT 8 UNION SELECT 9 ) d,
(SELECT 0 b UNION SELECT 10 UNION SELECT 20
UNION SELECT 30 UNION SELECT 40) m
WHERE '2016-01-05' + INTERVAL a + b DAY <= '2016-01-21')
You could also just change the @RequestParam default required status to false so that HTTP response status code 400 is not generated. This will allow you to place the Annotations in any order you feel like.
@RequestParam(required = false)String name
I can find following ways to do.
private static final String fileName = "C:/Input.txt";
public static void main(String[] args) throws IOException {
Stream<String> lines = Files.lines(Paths.get(fileName));
lines.toArray(String[]::new);
List<String> readAllLines = Files.readAllLines(Paths.get(fileName));
readAllLines.forEach(s -> System.out.println(s));
File file = new File(fileName);
Scanner scanner = new Scanner(file);
while (scanner.hasNext()) {
System.out.println(scanner.next());
}

There is no "canonical" way to do the matrix in C++, STL does not provide classes like "matrix". However there are some 3rd party libraries that do. You are encouraged to use them or write your own implementation. You can try my implementation derived from some public implementation found on the internet.
http://www.firstobject.com/dn_editor.htm is so far the best and lightest editor available with handful of utilities. I recommend using it - tried with up to 400 MB of files and more than a million records :)
Use Range("A1").Text
instead of .Value
post comment edit:
Why?
Because the .Text
property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92
then <- Text
will return exactly what it in the cell including any formatting.
The .Value
and .Value2
properties return what's stored in the cell under the hood excluding formatting. Specially .Value2
for date types, it will return the decimal representation.
If you want to dig deeper into the meaning and performance, I just found this article
which seems like a good guide
another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage
now,
paste this code in a module
Sub main()
Dim ws As Worksheet, i&, j&
Set ws = Sheets(1)
For i = 3 To 7
For j = 1 To 4
Debug.Print _
"row " & i & vbTab & vbTab & _
Cells(i, j).Text & vbTab & _
Cells(i, j).Value & vbTab & _
Cells(i, j).Value2
Next j
Next i
End Sub
and Analyse
the output! Its really easy and there isn't much more i can do to help :)

Here's another option for those not using heatmap.2
(aheatmap
is good!)
Make a sequential vector of 100 values from min to max of your input matrix, find value closest to 0 in that, make two vector of colours to and from desired midpoint, combine and use them:
breaks <- seq(from=min(range(inputMatrix)), to=max(range(inputMatrix)), length.out=100)
midpoint <- which.min(abs(breaks - 0))
rampCol1 <- colorRampPalette(c("forestgreen", "darkgreen", "black"))(midpoint)
rampCol2 <- colorRampPalette(c("black", "darkred", "red"))(100-(midpoint+1))
rampCols <- c(rampCol1,rampCol2)
Use:
string json = "{\r\n \"LOINC_NUM\": \"10362-2\",\r\n}";
var result = JObject.Parse(json.Replace(System.Environment.NewLine, string.Empty));
squares = squarer(x)
Arithmetic operations on arrays are automatically applied elementwise, with efficient C-level loops that avoid all the interpreter overhead that would apply to a Python-level loop or comprehension.
Most of the functions you'd want to apply to a NumPy array elementwise will just work, though some may need changes. For example, if
doesn't work elementwise. You'd want to convert those to use constructs like numpy.where
:
def using_if(x):
if x < 5:
return x
else:
return x**2
becomes
def using_where(x):
return numpy.where(x < 5, x, x**2)
(see detailed explanation here)
$text = Get-Content $filePath | Out-String
The IO.File.ReadAllText
didn't work for me with a relative path, it looks for the file in %USERPROFILE%\$filePath
instead of the current directory (when running from Powershell ISE at least):
$text = [IO.File]::ReadAllText($filePath)
$text = Get-Content $filePath -Raw
If you can't get text parsing to work using the accepted answer (e.g if your text file contains non uniform rows) then it's worth trying with Python's csv library - here's an example using a user defined Dialect:
import csv
csv.register_dialect('skip_space', skipinitialspace=True)
with open(my_file, 'r') as f:
reader=csv.reader(f , delimiter=' ', dialect='skip_space')
for item in reader:
print(item)
This is fairly easy to answer from the internet. Set system properties http.proxyHost
and http.proxyPort
. You can do this with System.setProperty()
, or from the command line with the -D
syntax.
-- Database Size
SELECT pg_size_pretty(pg_database_size('Database Name'));
-- Table Size
SELECT pg_size_pretty(pg_relation_size('table_name'));
Maybe a bit OT, but if you need this only for debuging to understand or retrace some binary operations you are doing, you might take a look on wcalc (a simple console calculator). With the -b options you get binary output.
e.g.
$ wcalc -b "(256 | 3) & 0xff" = 0b11
ExecuteNonQuery
This ExecuteNonQuery method will be used only for insert, update and delete, Create, and SET statements. ExecuteNonQuery method will return number of rows effected with INSERT, DELETE or UPDATE operations.
ExecuteScalar
It’s very fast to retrieve single values from database. Execute Scalar will return single row single column value i.e. single value, on execution of SQL Query or Stored procedure using command object. ExecuteReader
Execute Reader will be used to return the set of rows, on execution of SQL Query or Stored procedure using command object. This one is forward only retrieval of records and it is used to read the table values from first to last.
I used this way in my code
$(function(){
$('.block').affix();
})
__FILE__
is the filename with extension of the file containing the code being executed.
In foo.rb
, __FILE__
would be "foo.rb".
If foo.rb
were in the dir /home/josh
then File.dirname(__FILE__)
would return /home/josh
.
@johnstock, we can also use JavaScript's prototyping concept to add method to objects to delete any passed key available in calling object.
Above answers are appreciated.
var myObject = {
"ircEvent": "PRIVMSG",
"method": "newURI",
"regex": "^http://.*"
};
// 1st and direct way
delete myObject.regex; // delete myObject["regex"]
console.log(myObject); // { ircEvent: 'PRIVMSG', method: 'newURI' }
// 2 way - by using the concept of JavaScript's prototyping concept
Object.prototype.removeFromObjectByKey = function(key) {
// If key exists, remove it and return true
if (this[key] !== undefined) {
delete this[key]
return true;
}
// Else return false
return false;
}
var isRemoved = myObject.removeFromObjectByKey('method')
console.log(myObject) // { ircEvent: 'PRIVMSG' }
// More examples
var obj = {
a: 45,
b: 56,
c: 67
}
console.log(obj) // { a: 45, b: 56, c: 67 }
// Remove key 'a' from obj
isRemoved = obj.removeFromObjectByKey('a')
console.log(isRemoved); //true
console.log(obj); // { b: 56, c: 67 }
// Remove key 'd' from obj which doesn't exist
var isRemoved = obj.removeFromObjectByKey('d')
console.log(isRemoved); // false
console.log(obj); // { b: 56, c: 67 }

I had a similar problem for xml. Just passing the error and solution (edited Jonathon version).

String theXml = URLEncoder.encode( xmlContent, "UTF-8" );
HttpGet xmlGet = new HttpGet( theXml );
Any idea What i should be doing ? It just cleared passed but had problem while doing this
HttpResponse response = httpclient.execute( xmlGet );
You can also use a callable in the default field, such as:
b = models.CharField(max_length=7, default=foo)
And then define the callable:
def foo():
return 'bar'
A datetime.timedelta
corresponds to the difference between two dates, not a date itself. It's only expressed in terms of days, seconds, and microseconds, since larger time units like months and years don't decompose cleanly (is 30 days 1 month or 0.9677 months?).
If you want to convert a timedelta
into hours and minutes, you can use the total_seconds()
method to get the total number of seconds and then do some math:
x = datetime.timedelta(1, 5, 41038) # Interval of 1 day and 5.41038 seconds
secs = x.total_seconds()
hours = int(secs / 3600)
minutes = int(secs / 60) % 60

You can tweak and modify this code to make a better looking, more efficient contextmenu. As for modifying an existing contextmenu, I'm not sure how to do that... Check out this fiddle for an organized point of view. Also, try clicking the items in my contextmenu. They should alert you a few awesome messages. If they don't work, try something more... complex.
The *_test.go
file is a Go source like the others, you can initialize a new logger every time if you need to dump complex data structure, here an example:
// initZapLog is delegated to initialize a new 'log manager'
func initZapLog() *zap.Logger {
config := zap.NewDevelopmentConfig()
config.EncoderConfig.EncodeLevel = zapcore.CapitalColorLevelEncoder
config.EncoderConfig.TimeKey = "timestamp"
config.EncoderConfig.EncodeTime = zapcore.ISO8601TimeEncoder
logger, _ := config.Build()
return logger
}
Then, every time, in every test:
func TestCreateDB(t *testing.T) {
loggerMgr := initZapLog()
// Make logger avaible everywhere
zap.ReplaceGlobals(loggerMgr)
defer loggerMgr.Sync() // flushes buffer, if any
logger := loggerMgr.Sugar()
logger.Debug("START")
conf := initConf()
/* Your test here
if false {
t.Fail()
}*/
}
it works perfectly for me :
document.getElementById('iframe_id').contentWindow.document.body.innerHTML;

If you install the composer as global on Ubuntu, you just need to find the composer location.
Use command
type composer
or
where composer
For Mac users, use command:
which composer
and then just remove the folder using rm
command.
I see that this question is missing an answer. I extend Application
because I use Bill Pugh Singleton implementation (see reference) and some of my singletons need context. The Application
class looks like this:
public class MyApplication extends Application {
private static final String TAG = MyApplication.class.getSimpleName();
private static MyApplication sInstance;
@Contract(pure = true)
@Nullable
public static Context getAppContext() {
return sInstance;
}
@Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "onCreate() called");
sInstance = this;
}
}
And the singletons look like this:
public class DataManager {
private static final String TAG = DataManager.class.getSimpleName();
@Contract(pure = true)
public static DataManager getInstance() {
return InstanceHolder.INSTANCE;
}
private DataManager() {
doStuffRequiringContext(MyApplication.getAppContext());
}
private static final class InstanceHolder {
@SuppressLint("StaticFieldLeak")
private static final DataManager INSTANCE = new DataManager();
}
}
This way I don't need to have a context every time I'm using a singleton and get lazy synchronized initialization with minimal amount of code.
Tip: updating Android Studio singleton template saves a lot of time.

You use the ajaxStop to execute code when the ajax are completed:
$(document).ajaxStop(function(){
setTimeout("window.location = 'otherpage.html'",100);
});
Also on Apache 2,4 you may need to add this to the directory directive in conf, in case you decided to include httpd-vhosts.conf.
By default you can install wamp in C:\ but still choose to deploy your web development in another location.
To do this inside the vhosts.conf you can add this directive:
<Directory "e:/websites">
Options Indexes FollowSymLinks MultiViews
DirectoryIndex index.php
AllowOverride All
<IfDefine APACHE24>
Require local
</IfDefine>
<IfDefine !APACHE24>
Order Deny,Allow
Allow from all
Allow from localhost ::1 127.0.0.1
</IfDefine>
</Directory>
As you're using Python 3, there is no urllib module anymore. It has been split into several modules.
This would be equivalent to urlretrieve:
import urllib.request
data = urllib.request.urlretrieve("http://...")
urlretrieve behaves exactly the same way as it did in Python 2.x, so it'll work just fine.
Basically:
urlretrieve
saves the file to a temporary file and returns a tuple (filename, headers)
urlopen
returns a Request
object whose read
method returns a bytestring containing the file contentsInstall the extension "Code Runner". Check if you can compile your program with csc
(ex.: csc hello.cs
). The command csc
is shipped with Mono. Then add this to your VS Code user settings:
"code-runner.executorMap": {
"csharp": "echo '# calling mono\n' && cd $dir && csc /nologo $fileName && mono $dir$fileNameWithoutExt.exe",
// "csharp": "echo '# calling dotnet run\n' && dotnet run"
}
Open your C# file and use the execution key of Code Runner.
Edit: also added dotnet run
, so you can choose how you want to execute your program: with Mono, or with dotnet. If you choose dotnet, then first create the project (dotnet new console
, dotnet restore
).
you can consider something like that:
define a style for textblock, or any other control you want to use to display your enum:
<Style x:Key="enumStyle" TargetType="{x:Type TextBlock}">
<Setter Property="Text" Value="<NULL>"/>
<Style.Triggers>
<Trigger Property="Tag">
<Trigger.Value>
<proj:YourEnum>Value1<proj:YourEnum>
</Trigger.Value>
<Setter Property="Text" Value="{DynamicResource yourFriendlyValue1}"/>
</Trigger>
<!-- add more triggers here to reflect your enum -->
</Style.Triggers>
</Style>
define your style for ComboBoxItem
<Style TargetType="{x:Type ComboBoxItem}">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<TextBlock Tag="{Binding}" Style="{StaticResource enumStyle}"/>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
add a combobox and load it with your enum values:
<ComboBox SelectedValue="{Binding Path=your property goes here}" SelectedValuePath="Content">
<ComboBox.Items>
<ComboBoxItem>
<proj:YourEnum>Value1</proj:YourEnum>
</ComboBoxItem>
</ComboBox.Items>
</ComboBox>
if your enum is large, you can of course do the same in code, sparing a lot of typing. i like that approach, since it makes localization easy - you define all the templates once, and then, you only update your string resource files.
onclick buttons c2
to fetch and change the color of action bar and notification bar according to button's background, hope this helps
int color = c2.getBackground()).getColor();
int colorlighter = -color * 40 / 100 + color;
getWindow().setNavigationBarColor(colorlighter);
getWindow().setStatusBarColor(colorlighter);
ActionBar bar = getSupportActionBar();
bar.setBackgroundDrawable(new ColorDrawable(color));
colorlighter
is used to set color of notification bar a little lighter than action bar
color
is the background color of button c2
, according to which we change our color.
VirtualBox version has many uncompatibilities with Linux version, so it's hard to install by using "Guest Addition CD image". For linux distributions it's frequently have a good companion Guest Addition package(equivalent functions to the CD image) which can be installed by:
sudo apt-get install virtualbox-guest-dkms
After that, on the window menu of the Guest, go to Devices->Shared Folders Settings->Shared Folders and add a host window folder to Machine Folders(Mark Auto-mount option) then you can see the shared folder in the Files of Guest Linux.
Borrowed from @Deena above, that function modification for labels is more versatile than you might have thought. For example, I had a ggplot where the denominator of counted variables was 140. I used her example thus:
scale_y_continuous(labels = function(x) paste0(round(x/140*100,1), "%"), breaks = seq(0, 140, 35))
This allowed me to get my percentages on the 140 denominator, and then break the scale at 25% increments rather than the weird numbers it defaulted to. The key here is that the scale breaks are still set by the original count, not by your percentages. Therefore the breaks must be from zero to the denominator value, with the third argument in "breaks" being the denominator divided by however many label breaks you want (e.g. 140 * 0.25 = 35).
As an update to the OP's question, I can confirm that the timepicker found at http://jdewit.github.io/bootstrap-timepicker/ does in fact work with Bootstrap 3 now with no problems at all.
The usual approach is to uppercase the strings or lower case them for the lookups and comparisons. For example:
>>> "hello".upper() == "HELLO".upper()
True
>>>
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"
This is case, when object are better - because you can set up your object to hold x and y , set up defaults etc.
Approach with array is near to create object ( In fact, object is bunch of parameters and functions which will work over object, and function taking array will work over some bunch ov parameters )
Cerainly you can always do some tricks to set null or something like this as default

There is an alternative approach, which does not have I18n problems (allowing ',' or '.' but not both): Decimal.TryParse
.
Just try converting, ignoring the value.
bool IsDecimalFormat(string input) {
Decimal dummy;
return Decimal.TryParse(input, out dummy);
}
This is significantly faster than using a regular expression, see below.
(The overload of Decimal.TryParse
can be used for finer control.)

Most of the previous answers do a good job explaining how, why, and when to use onResume()
but I would like to add something about re-creating your Activity
.
I want to know if I want to restart the activity at the end of exectuion of an other what method is executed onCreate() or onResume()
The answer is onCreate()
However, when deciding to actually re-create it, you should ask yourself how much of the Activity
needs to be re-created. If it is data in an adapter, say for a list, then you can call notifyDataChanged()
on the adapter
to repopulate the adapter
and not have to redraw everything.
Also, if you just need to update certain views
but not all then it may be more efficient to call invalidate()
on the view
(s) that need updated. This will only redraw those views
and possibly allow your application to run more smoothly. I hope this can help you.
ALT+SHIFT+G will create the auto generated comments for your method (place the cursor at starting position of your method).
Take a look at the Cookie Plugin for jQuery.
I came across this problem today as well, though my particular issue probably isn't related to yours. After inspecting the list of files, I realized what I had done -- I had temporarily been using a file in one assembly from another assembly. I have made lots of changes to it and didn't want to orphan the SVN history, so in my branch I had moved the file over from the other assembly's folder. This isn't tracked by SVN, so it just looks like the file is deleted and then re-added. This ends up causing a tree conflict.
I resolved the problem by moving the file back, committing, and then merging my branch. Then I moved the file back afterward. :) That seemed to do the trick.
The three constants have similar functions nowadays, but different historical origins, and very occasionally you may be required to use one or the other.
You need to think back to the days of old manual typewriters to get the origins of this. There are two distinct actions needed to start a new line of text:
In computers, these two actions are represented by two different characters - carriage return is CR
, ASCII character 13, vbCr
; line feed is LF
, ASCII character 10, vbLf
. In the old days of teletypes and line printers, the printer needed to be sent these two characters -- traditionally in the sequence CRLF
-- to start a new line, and so the CRLF
combination -- vbCrLf
-- became a traditional line ending sequence, in some computing environments.
The problem was, of course, that it made just as much sense to only use one character to mark the line ending, and have the terminal or printer perform both the carriage return and line feed actions automatically. And so before you knew it, we had 3 different valid line endings: LF
alone (used in Unix and Macintoshes), CR
alone (apparently used in older Mac OSes) and the CRLF
combination (used in DOS, and hence in Windows). This in turn led to the complications of DOS / Windows programs having the option of opening files in text mode
, where any CRLF
pair read from the file was converted to a single CR
(and vice versa when writing).
So - to cut a (much too) long story short - there are historical reasons for the existence of the three separate line separators, which are now often irrelevant: and perhaps the best course of action in .NET is to use Environment.NewLine
which means someone else has decided for you which to use, and future portability issues should be reduced.
I used HttpRequestMessage and my problem got solved after doing so much research
[HttpPost]
public HttpResponseMessage PostProcedure(HttpRequestMessage req){
...
}
You have a few options:
First, you can use the JoinPoint#getArgs()
method which returns an Object[]
containing all the arguments of the advised method. You might have to do some casting depending on what you want to do with them.
Second, you can use the args
pointcut expression like so:
// use '..' in the args expression if you have zero or more parameters at that point
@Before("execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..)) && args(yourString,..)")
then your method can instead be defined as
public void logBefore(JoinPoint joinPoint, String yourString)
I personally use
myVar === undefined
Warning: Please note that ===
is used over ==
and that myVar
has been previously declared (not defined).
I do not like typeof myVar === "undefined"
. I think it is long winded and unnecessary. (I can get the same done in less code.)
Now some people will keel over in pain when they read this, screaming: "Wait! WAAITTT!!! undefined
can be redefined!"
Cool. I know this. Then again, most variables in Javascript can be redefined. Should you never use any built-in identifier that can be redefined?
If you follow this rule, good for you: you aren't a hypocrite.
The thing is, in order to do lots of real work in JS, developers need to rely on redefinable identifiers to be what they are. I don't hear people telling me that I shouldn't use setTimeout
because someone can
window.setTimeout = function () {
alert("Got you now!");
};
Bottom line, the "it can be redefined" argument to not use a raw === undefined
is bogus.
(If you are still scared of undefined
being redefined, why are you blindly integrating untested library code into your code base? Or even simpler: a linting tool.)
Also, like the typeof
approach, this technique can "detect" undeclared variables:
if (window.someVar === undefined) {
doSomething();
}
But both these techniques leak in their abstraction. I urge you not to use this or even
if (typeof myVar !== "undefined") {
doSomething();
}
Consider:
var iAmUndefined;
To catch whether or not that variable is declared or not, you may need to resort to the in
operator. (In many cases, you can simply read the code O_o).
if ("myVar" in window) {
doSomething();
}
But wait! There's more! What if some prototype chain magic is happening…? Now even the superior in
operator does not suffice. (Okay, I'm done here about this part except to say that for 99% of the time, === undefined
(and ****cough**** typeof
) works just fine. If you really care, you can read about this subject on its own.)
I have had a similar problem and this is how i solved it using the examples above:
$(".ms-drop").click(function () {
$(function showSelectedValues() {
alert($(".ms-drop input[type=checkbox]:checked").map(
function () { return this.value; }).get().join(","));
});
});
for Win10 you should remove this folder and close/open your IDE
C:\Users\User\AppData\Roaming\Subversion\auth
, also in my projects no ".subversion" folders, only ".svn"
In httpd.conf file you need to remove #
#LoadModule rewrite_module modules/mod_rewrite.so
after removing # line will look like this:
LoadModule rewrite_module modules/mod_rewrite.so
And Apache restart
From http://msdn.microsoft.com/en-us/library/ms176089.aspx
varchar [ ( n | max ) ] Variable-length, non-Unicode character data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of data entered + 2 bytes. The data entered can be 0 characters in length. The ISO synonyms for varchar are char varying or character varying.
1 character = 1 byte. And don't forget 2 bytes for the termination. So, 2^31-3 characters.
I would add another use case that seems straight forward when handling DB sessions:
# getting a DB connection
conn = db.engine.connect()
# and binding to a DB session
session = db.get_session(bind=conn)
try:
# we build the query to DB
q = session.query(MyTable).filter(MyTable.col1 == 'query_val')
# i.e retrieve one row
data_set = q.one_or_none()
# return results
return [{'col1': data_set.col1, 'col2': data_set.col2, ...}]
except:
# here we make sure to rollback the transaction,
# handy when we update stuff into DB
session.rollback()
raise
else:
# when no errors then we can commit DB changes
session.commit()
finally:
# and finally we can close the session
session.close()
Example of calculating time:
work-start work-stop lunchbreak effective time
07:30:00 17:00:00 1.5 8 [=((A2-A1)*24)-A3]
If you subtract one time value from another the result you get will represent the fraction of 24 hours, so if you multiply the result with 24 you get the value represented in hours.
In other words: the operation is mutiply, but the meaning is to change the format of the number (from days to hours).
What I do is to add a "?" for each possible value.
var stmt = String.format("select * from test where field in (%s)",
values.stream()
.collect(Collectors.joining(", ")));
Alternative using StringBuilder
(which was the original answer 10+ years ago)
List values = ...
StringBuilder builder = new StringBuilder();
for( int i = 0 ; i < values.size(); i++ ) {
builder.append("?,");
}
String placeHolders = builder.deleteCharAt( builder.length() -1 ).toString();
String stmt = "select * from test where field in ("+ placeHolders + ")";
PreparedStatement pstmt = ...
And then happily set the params
int index = 1;
for( Object o : values ) {
pstmt.setObject( index++, o ); // or whatever it applies
}
As far as I'm aware there is no built in php function to do this, you need to do it via a loop or via a custom method that recursively calls to something like array_fill inidcated in the answer by @Amber;
I'm assuming you mean created an empty but intialized array of arrays. For example, you want a final results like the below of a array of 3 arrays:
$final_array = array(array(), array(), array());
This is simple to just hand code, but for an arbitrary sized array like a an array of 3 arrays of 3 arrays it starts getting complex to initialize prior to use:
$final_array = array(array(array(), array(), array()), array(array(), array(), array()), array(array(), array(), array()));
...etc...
I get the frustration. It would be nice to have an easy way to declare an initialized array of arrays any depth to use without checking or throwing errors.
** Update ** A scalars converter has been added to retrofit that allows for a String
response with less ceremony than my original answer below.
Example interface --
public interface GitHubService {
@GET("/users/{user}")
Call<String> listRepos(@Path("user") String user);
}
Add the ScalarsConverterFactory
to your retrofit builder. Note: If using ScalarsConverterFactory
and another factory, add the scalars factory first.
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(ScalarsConverterFactory.create())
// add other factories here, if needed.
.build();
You will also need to include the scalars converter in your gradle file --
implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'
--- Original Answer (still works, just more code) ---
I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject
land. I suspect your specific problem might be better solved using a custom gson TypeAdapter
or a retrofit Converter
if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -
First, if you are using Retrofit 2, you should start using the Call
API. Instead of sending an object to convert as the type parameter, use ResponseBody
from okhttp --
public interface GitHubService {
@GET("/users/{user}")
Call<ResponseBody> listRepos(@Path("user") String user);
}
then you can create and execute your call --
GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Response<ResponseBody> response) {
try {
System.out.println(response.body().string());
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Throwable t) {
e.printStackTrace();
}
});
Note The code above calls string()
on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream()
instead. See the ResponseBody
docs.
If you're only interested in seeing the currently deleted files, you can use this:
git ls-files --deleted
if you then want to remove them (in case you deleted them not using "git rm") pipe that result to xargs git rm
git ls-files --deleted | xargs git rm
Oldest:
oldest = min(datetimes)
Youngest before now:
now = datetime.datetime.now(pytz.utc)
youngest = max(dt for dt in datetimes if dt < now)
moving element top: -12px or positioning it absolutely doesn't solve the problem but only masks it
I had the same problem - check if you have in one wrapping element mixed: floating elements with non-floating ones - my non-floating element caused this strange offset to the floating one
As it's 2018, use flexbox - no more inline-block
whitespace issues:
body {
margin: 0;
}
#wrapper {
display: flex;
height: 200px;
}
#wrapper > div {
flex-grow: 1;
}
#wrapper > div:first-of-type { background-color: red }
#wrapper > div:nth-of-type(2) { background-color: blue }
#wrapper > div:nth-of-type(3) { background-color: green }
_x000D_
<div id="wrapper">
<div id="c1"></div>
<div id="c2"></div>
<div id="c3"></div>
</div>
_x000D_
Or even CSS grid if you are creating a grid.
body {
margin: 0;
}
#wrapper {
display: grid;
grid-template-columns: repeat(3, 1fr);
grid-auto-rows: minmax(200px, auto);
}
#wrapper>div:first-of-type { background-color: red }
#wrapper>div:nth-of-type(2) { background-color: blue }
#wrapper>div:nth-of-type(3) { background-color: green }
_x000D_
<div id="wrapper">
<div id="c1"></div>
<div id="c2"></div>
<div id="c3"></div>
</div>
_x000D_
Use CSS calc()
:
body {
margin: 0;
}
div {
height: 200px;
width: 33.33%; /* as @passatgt mentioned in the comment, for the older browsers fallback */
width: calc(100% / 3);
display: inline-block;
}
div:first-of-type { background-color: red }
div:nth-of-type(2) { background-color: blue }
div:nth-of-type(3) { background-color: green }
_x000D_
<div></div><div></div><div></div>

The answer is not efficiency. Non-reentrant mutexes lead to better code.
Example: A::foo() acquires the lock. It then calls B::bar(). This worked fine when you wrote it. But sometime later someone changes B::bar() to call A::baz(), which also acquires the lock.
Well, if you don't have recursive mutexes, this deadlocks. If you do have them, it runs, but it may break. A::foo() may have left the object in an inconsistent state before calling bar(), on the assumption that baz() couldn't get run because it also acquires the mutex. But it probably shouldn't run! The person who wrote A::foo() assumed that nobody could call A::baz() at the same time - that's the entire reason that both of those methods acquired the lock.
The right mental model for using mutexes: The mutex protects an invariant. When the mutex is held, the invariant may change, but before releasing the mutex, the invariant is re-established. Reentrant locks are dangerous because the second time you acquire the lock you can't be sure the invariant is true any more.
If you are happy with reentrant locks, it is only because you have not had to debug a problem like this before. Java has non-reentrant locks these days in java.util.concurrent.locks, by the way.
How to create symlink in vagrant. Steps:
l = [1, 2, 3, 4, 5]
del l[0:3] # Here 3 specifies the number of items to be deleted.
This is the code if you want to delete a number of items from the list. You might as well skip the zero before the colon. It does not have that importance. This might do as well.
l = [1, 2, 3, 4, 5]
del l[:3] # Here 3 specifies the number of items to be deleted.

Please be aware that the examples for icon file path tend to assume that main.js is under the base directory. If the file is not in the base directory of the app, the path specification must account for that fact.
For example, if the main.js is under the src/ subdirectory, and the icon is under assets/icons/, this icon path specification will work:
icon: __dirname + "../assets/icons/icon.png"
array with zero elements converts to false

Definitely use a service to share data between controllers, here is a working example. $broadcast is not the way to go, you should avoid using the eventing system when there is a more appropriate way. Use a 'service', 'value' or 'constant' (for global constants).
http://plnkr.co/edit/ETWU7d0O8Kaz6qpFP5Hp
Here is an example with an input so you can see the data mirror on the page: http://plnkr.co/edit/DbBp60AgfbmGpgvwtnpU
var testModule = angular.module('testmodule', []);
testModule
.controller('QuestionsStatusController1',
['$rootScope', '$scope', 'myservice',
function ($rootScope, $scope, myservice) {
$scope.myservice = myservice;
}]);
testModule
.controller('QuestionsStatusController2',
['$rootScope', '$scope', 'myservice',
function ($rootScope, $scope, myservice) {
$scope.myservice = myservice;
}]);
testModule
.service('myservice', function() {
this.xxx = "yyy";
});
There is also http v2 which is a wrapper for curl. Can be installed via pecl.
That is the backbone of CSS, the "cascade" in Cascading Style Sheets.
If you write your CSS rules in a single line it makes it easier to see the structure:
.area1 .item { color:red; }
.area2 .item { color:blue; }
.area2 .item span { font-weight:bold; }
Using multiple classes is also a good intermediate/advanced use of CSS, unfortunately there is a well known IE6 bug which limits this usage when writing cross browser code:
<div class="area1 larger"> .... </div>
.area1 { width:200px; }
.area1.larger { width:300px; }
IE6 IGNORES the first selector in a multi-class rule, so IE6 actually applies the .area1.larger rule as
/*.area1*/.larger { ... }
Meaning it will affect ALL .larger elements.
It's a very nasty and unfortunate bug (one of many) in IE6 that forces you to pretty much never use that feature of CSS if you want one clean cross-browser CSS file.
The solution then is to use CSS classname prefixes to avoid colliding wiht generic classnames:
.area1 { ... }
.area1.area1Larger { ... }
.area2.area2Larger { ... }
May as well use just one class, but that way you can keep the CSS in the logic you intended, while knowing that .area1Larger only affects .area1, etc.
Look at my code, but be aware. I use async/await, because latest Chrome beta can read any es6 code, which gets by TypeScript with compilation. So, you must replace asyns/await by .then()
.
Input change handler:
/**
* @param fileInput
*/
public psdTemplateSelectionHandler (fileInput: any){
let FileList: FileList = fileInput.target.files;
for (let i = 0, length = FileList.length; i < length; i++) {
this.psdTemplates.push(FileList.item(i));
}
this.progressBarVisibility = true;
}
Submit handler:
public async psdTemplateUploadHandler (): Promise<any> {
let result: any;
if (!this.psdTemplates.length) {
return;
}
this.isSubmitted = true;
this.fileUploadService.getObserver()
.subscribe(progress => {
this.uploadProgress = progress;
});
try {
result = await this.fileUploadService.upload(this.uploadRoute, this.psdTemplates);
} catch (error) {
document.write(error)
}
if (!result['images']) {
return;
}
this.saveUploadedTemplatesData(result['images']);
this.redirectService.redirect(this.redirectRoute);
}
FileUploadService. That service also stored uploading progress in progress$ property, and in other places, you can subscribe on it and get new value every 500ms.

I'm using different ports then standard and copy files between files like this:
scp -P 1234 user@[ip address or host name]:/var/www/mywebsite/dumps/* /var/www/myNewPathOnCurrentLocalMachine
This is only for occasional use, if it repeats itself based on a schedule you should use rsync and cron job to do it.
Instead of <nav class="navbar ...

Use the monthdelta package, it works just like timedelta but for calendar months rather than days/hours/etc.
Here's an example:
from monthdelta import MonthDelta
def prev_month(date):
"""Back one month and preserve day if possible"""
return date + MonthDelta(-1)
Compare that to the DIY approach:
def prev_month(date):
"""Back one month and preserve day if possible"""
day_of_month = date.day
if day_of_month != 1:
date = date.replace(day=1)
date -= datetime.timedelta(days=1)
while True:
try:
date = date.replace(day=day_of_month)
return date
except ValueError:
day_of_month -= 1
NSPredicate
is nextstep's way of constructing condition to filter a collection (NSArray
, NSSet
, NSDictionary
).
For example consider two arrays arr
and filteredarr
:
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@",@"c"];
filteredarr = [NSMutableArray arrayWithArray:[arr filteredArrayUsingPredicate:predicate]];
the filteredarr will surely have the items that contains the character c alone.
to make it easy to remember those who little sql background it is
*--select * from tbl where column1 like '%a%'--*
1)select * from tbl --> collection
2)column1 like '%a%' --> NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@",@"c"];
3)select * from tbl where column1 like '%a%' -->
[NSMutableArray arrayWithArray:[arr filteredArrayUsingPredicate:predicate]];
I hope this helps
Have you added this gem to your gemfile?
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
move that gem out of assets group and then run bundle again, I hope that would help!
SessionAttribute
annotation is the simplest and straight forward instead of getting session from request object and setting attribute.
Any object can be added to the model in controller and it will stored in session if its name matches with the argument in @SessionAttributes
annotation.
In below eg, personObj
will be available in session.
@Controller
@SessionAttributes("personObj")
public class PersonController {
@RequestMapping(value="/person-form")
public ModelAndView personPage() {
return new ModelAndView("person-page", "person-entity", new Person());
}
@RequestMapping(value="/process-person")
public ModelAndView processPerson(@ModelAttribute Person person) {
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("person-result-page");
modelAndView.addObject("pers", person);
modelAndView.addObject("personObj", person);
return modelAndView;
}
}
As per DOC:
if-else statements don't work inside JSX. This is because JSX is just syntactic sugar for function calls and object construction.
Basic Rule:
JSX is fundamentally syntactic sugar. After compilation, JSX expressions become regular JavaScript function calls and evaluate to JavaScript objects. We can embed any JavaScript expression in JSX by wrapping it in curly braces.
But only expressions not statements, means directly we can not put any statement (if-else/switch/for) inside JSX.
If you want to render the element conditionally then use ternary operator
, like this:
render() {
return (
<View style={styles.container}>
{this.state.value == 'news'? <Text>data</Text>: null }
</View>
)
}
Another option is, call a function from jsx
and put all the if-else
logic inside that, like this:
renderElement(){
if(this.state.value == 'news')
return <Text>data</Text>;
return null;
}
render() {
return (
<View style={styles.container}>
{ this.renderElement() }
</View>
)
}
I found two ways to configure "SourceGear DiffMerge" as difftool and mergetool in github Windows.
The following commands in a Command Prompt window will update your .gitconfig to configure GIT use DiffMerge:
git config --global diff.tool diffmerge
git config --global difftool.diffmerge.cmd 'C:/Program\ Files/SourceGear/Common/DiffMerge/sgdm.exe \"$LOCAL\" \"$REMOTE\"'
git config --global merge.tool diffmerge
git config --global mergetool.diffmerge.cmd 'C:/Program\ Files/SourceGear/Common/DiffMerge/sgdm.exe -merge -result=\"$MERGED\" \"$LOCAL\" \"$BASE\" \"$REMOTE\"'
[OR]
Add the following lines to your .gitconfig. This file should be in your home directory in C:\Users\UserName:
[diff]
tool = diffmerge
[difftool "diffmerge"]
cmd = C:/Program\\ Files/SourceGear/Common/DiffMerge/sgdm.exe \"$LOCAL\" \"$REMOTE\"
[merge]
tool = diffmerge
[mergetool "diffmerge"]
trustExitCode = true
cmd = C:/Program\\ Files/SourceGear/Common/DiffMerge/sgdm.exe -merge -result=\"$MERGED\" \"$LOCAL\" \"$BASE\" \"$REMOTE\"
1) fragmentTransaction.addToBackStack(str);
Description - Add this transaction to the back stack. This means that the transaction will be remembered after it is committed, and will reverse its operation when later popped off the stack.
2) fragmentTransaction.replace(int containerViewId, Fragment fragment, String tag)
Description - Replace an existing fragment that was added to a container. This is essentially the same as calling remove(Fragment) for all currently added fragments that were added with the same containerViewId and then add(int, Fragment, String) with the same arguments given here.
3) fragmentTransaction.add(int containerViewId, Fragment fragment, String tag)
Description - Add a fragment to the activity state. This fragment may optionally also have its view (if Fragment.onCreateView returns non-null) into a container view of the activity.
What does it mean to replace an already existing fragment, and adding a fragment to the activity state and adding an activity to the back stack ?
There is a stack in which all the activities in the running state are kept. Fragments belong to the activity. So you can add them to embed them in a activity.
You can combine multiple fragments in a single activity to build a multi-pane UI and reuse a fragment in multiple activities. This is essentially useful when you have defined your fragment container at different layouts. You just need to replace with any other fragment in any layout.
When you navigate to the current layout, you have the id of that container to replace it with the fragment you want.
You can also go back to the previous fragment in the backStack with the popBackStack()
method. For that you need to add that fragment in the stack using addToBackStack()
and then commit()
to reflect. This is in reverse order with the current on top.
findFragmentByTag does this search for tag added by the add/replace method or the addToBackStack method ?
If depends upon how you added the tag. It then just finds a fragment by its tag that you defined before either when inflated from XML or as supplied when added in a transaction.
References: FragmentTransaction
In case you are using the annotation method for filter definition (as opposed to defining them in the web.xml
), you can do so by just putting an array of mappings in the @WebFilter
annotation:
/**
* Filter implementation class LoginFilter
*/
@WebFilter(urlPatterns = { "/faces/Html/Employee","/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginFilter implements Filter {
...
And just as an FYI, this same thing works for servlets using the servlet annotation too:
/**
* Servlet implementation class LoginServlet
*/
@WebServlet({"/faces/Html/Employee", "/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginServlet extends HttpServlet {
...
Try to use https://www.pagedjs.org/. It polyfills page counter, header-/footer-functionality for all major browsers.
@page {
@bottom-left {
content: counter(page) ' of ' counter(pages);
}
}
It's so much more comfortable compared to alternatives like PrinceXML, Antennahouse, WeasyPrince, PDFReactor, etc ...
And it is totally free! No pricing or whatever. It really saved my life!
Gradle looks for gradle.properties
files in these places:
GRADLE_USER_HOME
environment variable, which if not set defaults to USER_HOME/.gradle
)Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).
Reference: https://gradle.org/docs/current/userguide/build_environment.html
If you have an empty table the Export method won't work. As a workaround. I used the Table View of Oracle SQL Developer. and clicked on Columns. Sorted by Nullable so NO was on top. And then selected these non nullable values using shift + select for the range.
This allowed me to do one base insert. So that Export could prepare a proper all columns insert.
I had a problem with mime types and where making tests for few file types. It looks like each browser sends it's variation of a mime type for a specific file. I was trying to upload mp3 and zip files with open source php class, that what I have found:
So if you need several file types to upload, you better make some tests so that every browser could upload a file and pass mime type check.
a much more practical way for those who do not want to use regex:
$data = filter_var($data, FILTER_SANITIZE_NUMBER_INT);
note: it works with phone numbers too.
This will do the trick
.gallery-item
{
opacity:1;
}
.gallery-item:hover
{
opacity:0;
transition: opacity .2s ease-out;
-moz-transition: opacity .2s ease-out;
-webkit-transition: opacity .2s ease-out;
-o-transition: opacity .2s ease-out;
}
If this is UNIX:
sort -k 2 file.txt
You can use multiple -k
flags to sort on more than one column. For example, to sort by family name then first name as a tie breaker:
sort -k 2,2 -k 1,1 file.txt
Relevant options from "man sort":
-k, --key=POS1[,POS2]
start a key at POS1, end it at POS2 (origin 1)
POS is F[.C][OPTS], where F is the field number and C the character position in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key.
-t, --field-separator=SEP
use SEP instead of non-blank to blank transition
This is what I do on debian - I suspect it should work on ubuntu (amend the version as required + adapt the folder where you want to copy the JDK files as you wish, I'm using /opt/jdk
):
wget --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u71-b15/jdk-8u71-linux-x64.tar.gz
sudo mkdir /opt/jdk
sudo tar -zxf jdk-8u71-linux-x64.tar.gz -C /opt/jdk/
rm jdk-8u71-linux-x64.tar.gz
Then update-alternatives:
sudo update-alternatives --install /usr/bin/java java /opt/jdk/jdk1.8.0_71/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_71/bin/javac 1
Select the number corresponding to the /opt/jdk/jdk1.8.0_71/bin/java
when running the following commands:
sudo update-alternatives --config java
sudo update-alternatives --config javac
Finally, verify that the correct version is selected:
java -version
javac -version
When this happens the easiest solution is to make the virtual directory manually.
First of all, you need to make sure you have the right version of ASP.Net installed and that you have installed the IIS extensions.
To do this, go to the relevant .net version's folder in C:\(Windows)\Microsoft.NET\Framework\(dotnetver)\ (substituting the bracketed folders for the right folders on your PC) and run this command
aspnet_regiis.exe -i
Next once that's run and finished, sometimes running
iisreset
from the command line helps, sometimes you don't need to.
Next, go to your IIS Manager and find you localhost website and choose add a folder. Browse to the folder in your project that contains the actual ASP.Net project and add that.
Finally, right click on the folder you added and you should have an option that says 'convert to application' or 'create virtual directory' or something similar.
!!Make sure the Virtual directory has the name 'MyWebApp'!!
Reload your solution and it should work.
Please be wary; this isn't a programming question (and shouldn't really be posted here) but I've posted this guidance as it's a common problem, but the advice I've posted is generic; the commands I've listed are correct but the steps you need to do in IIS may vary, it depends on your version and your account privileges.
Good luck!
