Simply put this block of xml in your activity layout file:
<RelativeLayout
android:id="@+id/loadingPanel"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center" >
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="true" />
</RelativeLayout>
And when you finish loading, call this one line:
findViewById(R.id.loadingPanel).setVisibility(View.GONE);
The result (and it spins too):
For doing "normal" hash table lookups on basically any kind of data - this one by Paul Hsieh is the best I've ever used.
http://www.azillionmonkeys.com/qed/hash.html
If you care about cryptographically secure or anything else more advanced, then YMMV. If you just want a kick ass general purpose hash function for a hash table lookup, then this is what you're looking for.
There is an important detail that has been omitted in the answer above.
MySQL imposes a limit of 65,535 bytes for the max size of each row.
The size of a VARCHAR
column is counted towards the maximum row size, while TEXT
columns are assumed to be storing their data by reference so they only need 9-12 bytes. That means even if the "theoretical" max size of your VARCHAR
field is 65,535 characters you won't be able to achieve that if you have more than one column in your table.
Also note that the actual number of bytes required by a VARCHAR
field is dependent on the encoding of the column (and the content). MySQL counts the maximum possible bytes used toward the max row size, so if you use a multibyte encoding like utf8mb4
(which you almost certainly should) it will use up even more of your maximum row size.
Correction: Regardless of how MySQL computes the max row size, whether or not the VARCHAR
/TEXT
field data is ACTUALLY stored in the row or stored by reference depends on your underlying storage engine. For InnoDB the row format affects this behavior. (Thanks Bill-Karwin)
Reasons to use TEXT

For those that use coffeescript, I've put the code we use globally to disable the submit buttons on our most widely used form. An adaption of Adil's answer above.
$('#new_post button').prop 'disabled', true
$('#new_post #post_message').keyup ->
$('#new_post button').prop 'disabled', if @value == '' then true else false
return
I think what you want to do is
<link rel="stylesheet" type="text/css" href="font/font-face/my-font-face.css">
_x000D_
Please try this (if the browser does not support "onbeforeunload"):
jQuery(document).ready(function($) {
if (window.history && window.history.pushState) {
$(window).on('popstate', function() {
var hashLocation = location.hash;
var hashSplit = hashLocation.split("#!/");
var hashName = hashSplit[1];
if (hashName !== '') {
var hash = window.location.hash;
if (hash === '') {
alert('Back button was pressed.');
}
}
});
window.history.pushState('forward', null, './#forward');
}
});
@Lucius and @zyrolasting have it right.
However, you will probably need to give the form a specified width
for it to work properly.
form {
margin: 0 auto;
width:250px;
}
Just a note for people who may have found this later (and want java way of achieving this); FirefoxOptions
is also capable of enabling the headless mode:
FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setHeadless(true);
This article about CSS image replacement for submit buttons could help.
"Using this method you'll get a clickable image when style sheets are active, and a standard button when style sheets are off. The trick is to apply the image replace methods to a button tag and use it as the submit button, instead of using input.
And since button borders are erased, it's also recommendable change the button cursor to
the hand shaped one used for links, since this provides a visual tip to the users."
The CSS code:
#replacement-1 {
width: 100px;
height: 55px;
margin: 0;
padding: 0;
border: 0;
background: transparent url(image.gif) no-repeat center top;
text-indent: -1000em;
cursor: pointer; /* hand-shaped cursor */
cursor: hand; /* for IE 5.x */
}
#replacement-2 {
width: 100px;
height: 55px;
padding: 55px 0 0;
margin: 0;
border: 0;
background: transparent url(image.gif) no-repeat center top;
overflow: hidden;
cursor: pointer; /* hand-shaped cursor */
cursor: hand; /* for IE 5.x */
}
form>#replacement-2 { /* For non-IE browsers*/
height: 0px;
}
You were close. This will work:
.image { position: relative; border: 1px solid black; width: 200px; height: 200px; }
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; right:0; bottom:0; display: none; background-color: rgba(0,0,0,0.5); }
.image:hover .overlay { display: block; }
You needed to put the :hover
on image, and make the .overlay
cover the whole image by adding right:0;
and bottom:0
.

Thanks Hong, that was exactly the problem I was running into. The error you get suggests that the number of rows is wrong, but the problem is actually that the model has been trained using a command that ends up with the wrong names for parameters.
This is really a critical detail that is entirely non-obvious for lm and so on. Some of the tutorial make reference to doing lines like lm(olive$Area@olive$Palmitic)
- ending up with variable names of olive$Area NOT Area, so creating an entry using anewdata<-data.frame(Palmitic=2)
can't then be used. If you use lm(Area@Palmitic,data=olive)
then the variable names are right and prediction works.
The real problem is that the error message does not indicate the problem at all:
Warning message: 'anewdata' had 1 rows but variable(s) found to have X rows
You need to bind init before initialization.
$('.slider-for').on('init', function(event, slick){
$(this).append('<div class="slider-count"><p><span id="current">1</span> von <span id="total">'+slick.slideCount+'</span></p></div>');
});
$('.slider-for').slick({
slidesToShow: 1,
slidesToScroll: 1,
arrows: true,
fade: true
});
$('.slider-for')
.on('afterChange', function(event, slick, currentSlide, nextSlide){
// finally let's do this after changing slides
$('.slider-count #current').html(currentSlide+1);
});

Alternative:

Very nice example using paste and substitute to typeset both symbols (mathplot) and variables at http://vis.supstat.com/2013/04/mathematical-annotation-in-r/
Here is a ggplot adaptation
library(ggplot2)
x_mean <- 1.5
x_sd <- 1.2
N <- 500
n <- ggplot(data.frame(x <- rnorm(N, x_mean, x_sd)),aes(x=x)) +
geom_bar() + stat_bin() +
labs(title=substitute(paste(
"Histogram of random data with ",
mu,"=",m,", ",
sigma^2,"=",s2,", ",
"draws = ", numdraws,", ",
bar(x),"=",xbar,", ",
s^2,"=",sde),
list(m=x_mean,xbar=mean(x),s2=x_sd^2,sde=var(x),numdraws=N)))
print(n)
GNU cp
has an option to create symlinks instead of copying.
cp -rs /mnt/usr/lib /usr/
Note this is a GNU extension not found in POSIX cp

If the array is not sorted, you will have to iterate over everything and make a call to equals on each.
If the array is sorted, you can do a binary search, there's one in the Arrays class.
Generally speaking, if you are going to do a lot of membership checks, you may want to store everything in a Set, not in an array.

C:\Program Files\MongoDB\Server\3.6\bin>mongod --install --config C:\data\mongo.config --logpath="c:/data/log/mongo.log"
If old MongoDB service exists then need to delete the old service first before mongod --install command, run the following in a new console to delete old mongodb service
SC STOP MongoDB
>> SC DELETE MongoDB
Type the following to start MongoDB
C:\Program Files\MongoDB\Server\3.6\bin>net start MongoDB
Type the following to stop MongoDB
C:\Program Files\MongoDB\Server\3.6\bin>net stop MongoDB
Now connect the DB on ip - 127.0.0.1 or 192.168.5.64 on port 27017 .

SQL Server returns messages after a batch of statements has been executed. Normally, you'd use SQL GO
to indicate the end of a batch and to retrieve the results:
PRINT '1'
GO
WAITFOR DELAY '00:00:05'
PRINT '2'
GO
WAITFOR DELAY '00:00:05'
PRINT '3'
GO
In this case, however, the print statement you want returned immediately is in the middle of a loop, so the print statements cannot be in their own batch. The only command I know of that will return in the middle of a batch is RAISERROR (...) WITH NOWAIT
, which gbn has provided as an answer as I type this.
Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.
e.g. if you do this:
SELECT 1 / 2
you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.
e.g.
SELECT CAST(1 AS DECIMAL) / 2
gives 0.500000
To solve this problem in Excel, usually I would just type in the literal row number of the cell above, e.g., if I'm typing in Cell A7
, I would use the formula =A6
. Then if I copied that formula to other cells, they would also use the row of the previous cell.
Another option is to use Indirect()
, which resolves the literal statement inside to be a formula. You could use something like:
=INDIRECT("A" & ROW() - 1)
The above formula will resolve to the value of the cell in column A
and the row that is one less than that of the cell which contains the formula.
Taking @Mike Houston's answer as pointer, here is a complete sample code that does Signature and Hash and encryption.

Security.addProvider(provider);
}
String plainText = "This is a plain text!!";
// KeyPair
KeyPairGenerator keyPairGenerator = null;
if (null != provider)
keyPairGenerator = KeyPairGenerator.getInstance("RSA", provider);
else
keyPairGenerator = KeyPairGenerator.getInstance("RSA");
keyPairGenerator.initialize(2048);
KeyPair keyPair = keyPairGenerator.generateKeyPair();
// Signature
Signature signatureProvider = null;
if (null != provider)
signatureProvider = Signature.getInstance("SHA256WithRSA", provider);
else
signatureProvider = Signature.getInstance("SHA256WithRSA");
signatureProvider.initSign(keyPair.getPrivate());
signatureProvider.update(plainText.getBytes());
byte[] signature = signatureProvider.sign();
System.out.println("Signature Output : ");
System.out.println("\t" + new String(Base64.encode(signature)));
// Message Digest

You can use BouncyCastle Provider or default Sun Provider.
For regex, I first look at this web site: RegExLib.com
SELECT TOP 1 ID, Name, Score, [Date]
FROM myTable
WHERE ID = 2
Order BY [Date]
This is an example for a RelativeLayout:
RelativeLayout relativeLayout=(RelativeLayout)vi.findViewById(R.id.RelativeLayoutLeft);
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
relativeLayout.setLayoutParams(params);
With another kind of layout (example LinearLayout) you just simply has to change RelativeLayout for LinearLayout.
Your HTML file is not going to interact with C# directly, but you can write some C# to behave as if it were the HTML file.
For example: there is a class called System.Net.WebClient with simple methods:
using System.Net;
using System.Collections.Specialized;
...
using(WebClient client = new WebClient()) {
NameValueCollection vals = new NameValueCollection();
vals.Add("test", "test string");
client.UploadValues("http://www.someurl.com/page.php", vals);
}
For more documentation and features, refer to the MSDN page.
If you need the width of something that's hidden and you can't un-hide it for whatever reason, you can clone it, change the CSS so it displays off the page, make it invisible, and then measure it. The user will be none the wiser if it's hidden and deleted afterwards.
Some of the other answers here just make the visibility hidden which works, but it will take up a blank spot on your page for a fraction of a second.
Example:
$itemClone = $('.hidden-item').clone().css({
'visibility': 'hidden',
'position': 'absolute',
'z-index': '-99999',
'left': '99999999px',
'top': '0px'
}).appendTo('body');
var width = $itemClone.width();
$itemClone.remove();
You may be using old version of Mysql but surely you can use
DELETE FROM konta WHERE taken <> ''
But there are many other options available. You can try the following ones
DELETE * from konta WHERE strcmp(taken, '') <> 0;
DELETE * from konta where NOT (taken = '');
You don't give us the language, but if your regex flavour support look behind assertion, this is what you need:
.*(?<!a)$
(?<!a)
is a negated lookbehind assertion that ensures, that before the end of the string (or row with m
modifier), there is not the character "a".
See it here on Regexr
You can also easily extend this with other characters, since this checking for the string and isn't a character class.
.*(?<!ab)$
This would match anything that does not end with "ab", see it on Regexr
This will do:
/^(apple|banana)$/
to exclude from captured strings (e.g. $1
,$2
):
(?:apple|banana)
I'm not sure why there are so many contorted descriptions of doing this. Perhaps because Android Studio (AS) is constantly changing/evolving? Nevertheless, the procedure is this simple.
Assuming you have already installed Gradle in a suitable directory, mean that you probably also defined an environment variable for GRADLE_HOME
, if not define it now, and restart AS.
For my example: GRADLE_HOME=C:\Gradle\gradle-5.2.1
Then fire up AS and navigate to:
File > Settings > Build, Execution, Deployment > Gradle
Now, all you need to do is to select: (o) Use local gradle distribution
.
AS will then tell you it found your local Gradle paths:
Hit Apply
and Ok
and restart AS.
Now all the Gradle data can be found in your HOME directory, usually located here (in this case on Windows):
# tree -L 2 $USERPROFILE/.gradle/ | tail -n +2
+-- build-scan-data
¦ +-- 2.1
¦ +-- 2.2.1

Late resurrection.
Your query seems very similar to the one at page 259 of the book Pro JPA 2: Mastering the Java Persistence API, which in JPQL reads:
SELECT e
FROM Employee e
WHERE e IN (SELECT emp
FROM Project p JOIN p.employees emp
WHERE p.name = :project)
Using EclipseLink + H2 database, I couldn't get neither the book's JPQL nor the respective criteria working. For this particular problem I have found that if you reference the id directly instead of letting the persistence provider figure it out everything works as expected:
SELECT e
FROM Employee e
WHERE e.id IN (SELECT emp.id
FROM Project p JOIN p.employees emp
WHERE p.name = :project)
Finally, in order to address your question, here is an equivalent strongly typed criteria query that works:
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Employee> c = cb.createQuery(Employee.class);
Root<Employee> emp = c.from(Employee.class);
Subquery<Integer> sq = c.subquery(Integer.class);
Root<Project> project = sq.from(Project.class);
Join<Project, Employee> sqEmp = project.join(Project_.employees);
sq.select(sqEmp.get(Employee_.id)).where(
cb.equal(project.get(Project_.name),
cb.parameter(String.class, "project")));
c.select(emp).where(
cb.in(emp.get(Employee_.id)).value(sq));
TypedQuery<Employee> q = em.createQuery(c);
q.setParameter("project", projectName); // projectName is a String
List<Employee> employees = q.getResultList();
I just went into the manifest and changed android:label="...." to the name of the application. Once Id changed this, the title and the actual app name changed to that :)
The latest way to go is to use the unit 'ch' which stands for character.
You can simply write:
p {
max-width: 75ch;
}
The only trick is that whitespaces won't be counted as characters..

I had the same problem but I solved it differently. I don't know if it's a good way of doing it, but it works great for what I need.
I used @Inject on the constructor of the child component, like this:
import { Component, OnInit, Inject } from '@angular/core';
import { ParentComponent } from '../views/parent/parent.component';
export class ChildComponent{
constructor(@Inject(ParentComponent) private parent: ParentComponent){
}
someMethod(){
this.parent.aPublicProperty = 2;
}
}
This worked for me, you only need to declare the method or property you want to call as public.
In my case, the AppComponent handles the routing, and I'm using badges in the menu items to alert the user that new unread messages are available. So everytime a user reads a message, I want that counter to refresh, so I call the refresh method so that the number at the menu nav gets updated with the new value. This is probably not the best way but I like it for its simplicity.

This thing might help if your working with android N and below
File file=new File(Environment.getExternalStorageDirectory()+"/directoryname/"+filename);
Uri path= FileProvider.getUriForFile(MainActivity.this,BuildConfig.APPLICATION_ID + ".provider",file);
Intent intent=new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path,"image/*");
intent.setFlags(FLAG_GRANT_READ_URI_PERMISSION | FLAG_GRANT_WRITE_URI_PERMISSION); //must for reading data from directory
For example, you can pluck all fields from a result like this below.
I am picking out the 'balance' from an array and save to a variable
$kii = $user->pluck('balance');
then on the next line u can sum like this:
$sum = $kii->sum();
Hope it helps.
These two procedures let me reset the sequence and reset the sequence based on data in a table (apologies for the coding conventions used by this client):
CREATE OR REPLACE PROCEDURE SET_SEQ_TO(p_name IN VARCHAR2, p_val IN NUMBER)
AS
l_num NUMBER;
BEGIN
EXECUTE IMMEDIATE 'select ' || p_name || '.nextval from dual' INTO l_num;
-- Added check for 0 to avoid "ORA-04002: INCREMENT must be a non-zero integer"
IF (p_val - l_num - 1) != 0
THEN
EXECUTE IMMEDIATE 'alter sequence ' || p_name || ' increment by ' || (p_val - l_num - 1) || ' minvalue 0';
END IF;
EXECUTE IMMEDIATE 'select ' || p_name || '.nextval from dual' INTO l_num;
EXECUTE IMMEDIATE 'alter sequence ' || p_name || ' increment by 1 ';
DBMS_OUTPUT.put_line('Sequence ' || p_name || ' is now at ' || p_val);
END;
CREATE OR REPLACE PROCEDURE SET_SEQ_TO_DATA(seq_name IN VARCHAR2, table_name IN VARCHAR2, col_name IN VARCHAR2)
AS
nextnum NUMBER;
BEGIN
EXECUTE IMMEDIATE 'SELECT MAX(' || col_name || ') + 1 AS n FROM ' || table_name INTO nextnum;
SET_SEQ_TO(seq_name, nextnum);
END;
I came up with what I feel is a much better solution allowing:
no need for 'this._', that/self, weakmaps, symbols etc. Clear and straightforward 'class' code
private variables and methods are really private and have the correct 'this' binding
No use of 'this' at all which means clear code that is much less error prone
public interface is clear and separated from the implementation as a proxy to private methods
allows easy composition
with this you can do:
function Counter() {_x000D_
// public interface_x000D_
const proxy = {_x000D_
advance, // advance counter and get new value_x000D_
reset, // reset value_x000D_
value // get value_x000D_
}_x000D_
_x000D_
// private variables and methods_x000D_
let count=0;_x000D_
_x000D_
function advance() {_x000D_
return ++count;_x000D_
}_x000D_
_x000D_
function reset(newCount) {_x000D_
count=(newCount || 0);_x000D_
}_x000D_
_x000D_
function value() {_x000D_
return count;_x000D_
}_x000D_
_x000D_
return proxy;_x000D_
}_x000D_
_x000D_
let counter=Counter.New();_x000D_
console.log(counter instanceof Counter); // true_x000D_
counter.reset(100);_x000D_
console.log('Counter next = '+counter.advance()); // 101_x000D_
console.log(Object.getOwnPropertyNames(counter)); // ["advance", "reset", "value"]

I had this problem in one of my apps, now, I know this is an old thread but here is my solution; I figured out by looking at the data inside the debugger that JVM actually didn't load it properly when Hibernate was trying to update the database (that is actually done in a different thread), so I added the keyword "volatile" to every field of the entities. It has some performance issues to do that but rather that than Heavy objects beeing thrown around...
I implemented a max heap version of heapq and submitted it to PyPI. (Very slight change of heapq module CPython code.)
https://pypi.python.org/pypi/heapq_max/
https://github.com/he-zhe/heapq_max
Installation
pip install heapq_max
Usage
tl;dr: same as heapq module except adding ‘_max’ to all functions.
heap_max = [] # creates an empty heap
heappush_max(heap_max, item) # pushes a new item on the heap
item = heappop_max(heap_max) # pops the largest item from the heap
item = heap_max[0] # largest item on the heap without popping it
heapify_max(x) # transforms list into a heap, in-place, in linear time
item = heapreplace_max(heap_max, item) # pops and returns largest item, and
# adds new item; the heap size is unchanged

The encryption methods described are symmetric key block ciphers.
Data Encryption Standard (DES) is the predecessor, encrypting data in 64-bit blocks using a 56 bit key. Each block is encrypted in isolation, which is a security vulnerability.
Triple DES extends the key length of DES by applying three DES operations on each block: an encryption with key 0, a decryption with key 1 and an encryption with key 2. These keys may be related.
DES and 3DES are usually encountered when interfacing with legacy commercial products and services.
AES is considered the successor and modern standard. http://en.wikipedia.org/wiki/Advanced_Encryption_Standard
I believe the use of Blowfish is discouraged.
It is highly recommended that you do not attempt to implement your own cryptography and instead use a high-level implementation such as GPG for data at rest or SSL/TLS for data in transit. Here is an excellent and sobering video on encryption vulnerabilities http://rdist.root.org/2009/08/06/google-tech-talk-on-common-crypto-flaws/

To revert a migration:
python manage.py migrate <APP_NAME> <MIGRATION_NUMBER_PREFIX>
MIGRATION_NUMBER_PREFIX
is the number prefix of the migration you want to revert to, for instance 0001
to go to 0001_initial.py
migration. then you can delete that migration.
You can use
zero
as your migration number to revert all migrations of an app.

OutputStream output = new OutputStream() {

}
//Netbeans IDE automatically overrides this toString()
public String toString() {
return this.string.toString();
}
};
method call =>> marshaller.marshal( (Object) toWrite , (OutputStream) output);
then to print the string or get it just reference the "output" stream itself
As an example, to print the string out to console =>> System.out.println(output);
FYI: my method call marshaller.marshal(Object,Outputstream)
is for working with XML. It is irrelevant to this topic.
This is highly wasteful for productional use, there is a way too many conversion and it is a bit loose. This was just coded to prove to you that it is totally possible to create a custom OuputStream and output a string. But just go Horcrux7 way and all is good with merely two method calls.

means hexadecimal (base 16).
Thus, 0x400 = 4×(162) + 0×(161) + 0×(160) = 4×((24)2) = 22 × 28 = 210 = 1024, or one binary K.
And so 0x6400 = 0x4000 + 0x2400 = 0x19×0x400 = 25K
I had similar problem with IntelliJ when tried to run some Groovy scripts. Here is how I solved it.
Go to "Project Structure"-> "Project" -> "Project language level" and select "SDK default". This should use the same SDK for all project modules.
Bit of a late response but I noticed that this information can be hard to find and haven't found the answer on SO, so here it is.
Try a differnt parameter #view=FitH to force it to fit in the horzontal space and also you need to start the querystring off with a # rather than an & making it:
filename.pdf#view=FitH
What I've noticed it is that this will work if adobe reader is embedded in the browser but chrome will use it's own version of the reader and won't respond in the same way. In my own case, the chrome browser zoomed to fit width by default, so no problem , but Internet Explorer needed the above parameters to ensure the link always opened the pdf page with the correct view setting.
For a full list of available parameters see this doc
EDIT: (lazy mode on)
As of 2015, it now just works.
<input type="file">
This will ask user for the upload of any file. On iOS 8.x this can be a camera video, camera photo, or a photo/video from Photo Library.
<input type="file" accept="image/*">
This is as above, but limits the uploads to photos only from camera or library, no videos.
As @Jared Ng and @Issun pointed out, the key to solve this kind of RegEx like "matching everything up to a certain word or substring" or "matching everything after a certain word or substring" is called "lookaround" zero-length assertions. Read more about them here.
In your particular case, it can be solved by a positive look ahead: .+?(?=abc)
A picture is worth a thousand words. See the detail explanation in the screenshot.
Had this problem with angular, using an auth interceptor to edit the header, before the request gets executed. We used an api-token for authentification, so i had credentials enabled. now, it seems it is not neccessary/allowed anymore
@Injectable()
export class AuthInterceptor implements HttpInterceptor {
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
req = req.clone({
//withCredentials: true, //not needed anymore
setHeaders: {
'Content-Type' : 'application/json',
'API-TOKEN' : 'xxx'
},
});
return next.handle(req);
}
Besides that, there is no side effects right now.
I had the similar issue. its resolved for me with a simple command.
lsnrctl start
The Network Adapter exception is caused because:
lsnrctl
utility.Try to start the listener using the command prompt:
cmd
in the search field, and when cmd
shows up in the list of options, right click it and select ‘Run as Administrator’.lsnrctl start
without the quotes and press Enter.Exit
and press Enter.Hope it helps.
Based on the answers provided, I decided to make a quick plugin to do this:
(function($){
$.fn.moveTo = function(selector){
return this.each(function(){
var cl = $(this).clone();
$(cl).appendTo(selector);
$(this).remove();
});
};
})(jQuery);
Usage:
$('#nodeToMove').moveTo('#newParent');
Java Beans are not the same thing as EJBs.
The JavaBeans specification in Java 1.0 was Sun's attempt to allow Java objects to be manipulated in an IDE that looked like VB. There were rules laid down for objects that qualified as "Java Beans":
EJBs came later. They combine distributed components and a transactional model, running in a container that manages threads, pooling, life cycle, and provides services. They are a far cry from Java Beans.
DTOs came about in the Java context because people found out that the EJB 1.0 spec was too "chatty" with the database. Rather than make a roundtrip for every data element, people would package them into Java Beans in bulk and ship them around.
POJOs were a reaction against EJBs.

I made a small tool providing similar functionality, without using xclip or xsel. stdout
is copied to a clipboard and can be pasted again in the terminal. See:
https://sourceforge.net/projects/commandlinecopypaste/
Note, that this tool does not need an X-session. The clipboard can just be used within the terminal and has not to be pasted by Ctrl+V or middle-mouse-click into other X-windows.
I faced the same error and in my case, I change the Server Port Number to 3308 where previously it was 3306. This connect my project to the MySQL database.
Here we have to change the connection code also.
Class.forName("com.mysql.cj.jdbc.Driver");
cn=(java.sql.Connection)DriverManager.getConnection("jdbc:mysql://localhost:3308/test2?zeroDateTimeBehavior=convertToNull","root","");
Changing the port number in the connection code is also necessary as localhost:3308
to resolved the error.
Suspend the process with CTRL+Z then use the command bg
to resume it in background. For example:
sleep 60
^Z #Suspend character shown after hitting CTRL+Z
[1]+ Stopped sleep 60 #Message showing stopped process info
bg #Resume current job (last job stopped)
More about job control and bg
usage in bash
manual page:
JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.
EDIT
To start a process where you can even kill the terminal and it still carries on running
nohup [command] [-args] > [filename] 2>&1 &
e.g.
nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &
To just ignore the output (not very wise) change the filename to /dev/null
To get the error message set to a different file change the &1
to a filename.
In addition: You can use the jobs
command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1
or kill %2
with the number being the index of the process.
Here sed

It depends on whether you process IDNs before or after the IDN toASCII
algorithm (that is, do you see the domain name pa??de??µa.d???µ?
in Greek or as xn--hxajbheg2az3al.xn--jxalpdlp
?).
In the latter case—where you are handling IDNs through the punycode—the old RFC 1123 rules apply:
U+0041 through U+005A (A-Z), U+0061 through U+007A (a-z) case folded as each other, U+0030 through U+0039 (0-9) and U+002D (-).
and U+002E (.) of course; the rules for labels allow the others, with dots between labels.
If you are seeing it in IDN form, the allowed characters are much varied, see http://unicode.org/reports/tr36/idn-chars.html for a handy chart of all valid characters.
Chances are your network code will deal with the punycode, but your display code (or even just passing strings to and from other layers) with the more human-readable form as nobody running a server on the ????????. domain wants to see their server listed as being on .xn--mgberp4a5d4ar
.
This question is asked in a lot of places in a lot of different ways. I originally answered it here but I feel it's relevant in this thread as well (since i ended up here when I was searching for an answer).
There is no one line solution to this problem, but this worked for my use case. The problem is, the 'View(context, attrs, defStyle)' constructor does not refer to an actual style, it wants an attribute. So, we will:
In 'res/values/attrs.xml', define a new attribute:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="customTextViewStyle" format="reference"/>
...
</resources>
In res/values/styles.xml' I'm going to create the style I want to use on my custom TextView
<style name="CustomTextView">
<item name="android:textSize">18sp</item>
<item name="android:textColor">@color/white</item>
<item name="android:paddingLeft">14dp</item>
</style>
In 'res/values/themes.xml' or 'res/values/styles.xml', modify the theme for your application / activity and add the following style:
<resources>
<style name="AppBaseTheme" parent="android:Theme.Light">
<item name="@attr/customTextViewStyle">@style/CustomTextView</item>
</style>
...
</resources>
Finally, in your custom TextView, you can now use the constructor with the attribute and it will receive your style
public class CustomTextView extends TextView {
public CustomTextView(Context context) {
super(context, null, R.attr.customTextView);
}
}
It's worth noting that I repeatedly used customTextView in different variants and different places, but it is in no way required that the name of the view match the style or the attribute or anything. Also, this technique should work with any custom view, not just TextViews.
You should not use your domain models
in your views. ViewModels
are the correct way to do it.
You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.
If you never heard of viewmodels, take a look at this.
You need to iterate the 2d array in order to get the min value of each row, then you have to push any gotten min value to another array and finally you need to get the min value of the array where each min row value was pushed
def get_min_value(self, table):
min_values = []
for i in range(0, len(table)):
min_value = min(table[i])
min_values.append(min_value)
return min(min_values)
This solution also work for background menu: http://www.roggel.com/NGNeer/BackgroundCMD/
In your case the starting time (20:11:13) is larger than the ending time (14:49:00). It is a reasonable assumption that you could solve the problem by adding a day on the ending time or subtracting a day from the starting time. if you do so, you will be trapped because you do not know on which day the testing time is.
You can avoid this trap by checking whether your testing time is between the ending time and starting time. If true, then result is "not in between"; else result is "well in between".
Here is the function in JAVA I have been using. It works so far for me. Good luck.
boolean IsTimeInBetween(Calendar startC, Calendar endC, Calendar testC){
// assume year, month and day of month are all equal.
startC.set(1,1,1);
endC.set(1,1,1);
testC.set(1,1,1);
if (endC.compareTo(startC) > 0) {
if ((testC.compareTo(startC)>=0) && (testC.compareTo(endC)<=0)) {
return true;
}else {
return false;
}
}else if (endC.compareTo(startC) < 0) {
if ((testC.compareTo(endC) >= 0) && (testC.compareTo(startC) <= 0)) {
return false;
} else {
return true;
}
} else{ // when endC.compareTo(startC)==0, I return a ture value. Change it if you have different application.
return true;
}
}
To create a Calender instance you can use:
Calendar startC = Calendar.getInstance();
startC.set(Calendar.HOUR_OF_DAY, 20);
startC.set(Calendar.MINUTE,11);
startC.set(Calendar.SECOND,13);
@CaptSolo, I tried your example, but it didn't work.
from itertools import groupby
[(c,len(list(cs))) for c,cs in groupby('Pedro Manoel')]
Output:
[('P', 1), ('e', 1), ('d', 1), ('r', 1), ('o', 1), (' ', 1), ('M', 1), ('a', 1), ('n', 1), ('o', 1), ('e', 1), ('l', 1)]
As you can see, there are two o's and two e's, but they got into separate groups. That's when I realized you need to sort the list passed to the groupby function. So, the correct usage would be:
name = list('Pedro Manoel')
name.sort()
[(c,len(list(cs))) for c,cs in groupby(name)]
Output:
[(' ', 1), ('M', 1), ('P', 1), ('a', 1), ('d', 1), ('e', 2), ('l', 1), ('n', 1), ('o', 2), ('r', 1)]
Just remembering, if the list is not sorted, the groupby function will not work!

Hashable = capable of being hashed.
Ok, what is hashing? A hashing function is a function which takes an object, say a string such as “Python,” and returns a fixed-size code. For simplicity, assume the return value is an integer.
When I run hash(‘Python’) in Python 3, I get 5952713340227947791 as the result. Different versions of Python are free to change the underlying hash function, so you will likely get a different value. The important thing is that no matter now many times I run hash(‘Python’), I’ll always get the same result with the same version of Python.
But hash(‘Java’) returns 1753925553814008565. So if the object I am hashing changes, so does the result. On the other hand, if the object I am hashing does not change, then the result stays the same.
Why does this matter?
Well, Python dictionaries, for example, require the keys to be immutable. That is, keys must be objects which do not change. Strings are immutable in Python, as are the other basic types (int, float, bool). Tuples and frozensets are also immutable. Lists, on the other hand, are not immutable (i.e., they are mutable) because you can change them. Similarly, dicts are mutable.
So when we say something is hashable, we mean it is immutable. If I try to pass a mutable type to the hash() function, it will fail:
>>> hash('Python')
1687380313081734297
>>> hash('Java')
1753925553814008565
>>>
>>> hash([1, 2])

I think you want something along the lines of this:

Or if you want a new line:
echo Your Msg>> YourTxtFile.txt
These commands are great for logs.

For someone who need to update the PHP version in WAMP, I can recommend this http://wampserver.aviatechno.net/
I had a problems with updating too, but on this website are Wampserver addons like new php version (php 7.1.4 etc.) And you don't have to manually edit files like php.ini or phpForApache.
Enjoy!
Or You can use
grep -n . file1 |tail -LineNumberToStartWith|grep regEx
This will take care of numbering the lines in the file
grep -n . file1
This will print the last-LineNumberToStartWith
tail -LineNumberToStartWith
And finally it will grep your desired lines(which will include line number as in orignal file)
grep regEX

This is one solution. If you want to make it more generic, you can use the StringUtils
library.
String value = "{first_name = naresh,last_name = kumar,gender = male}";
value = value.substring(1, value.length()-1); //remove curly brackets
String[] keyValuePairs = value.split(","); //split the string to creat key-value pairs
Map<String,String> map = new HashMap<>();
for(String pair : keyValuePairs) //iterate over the pairs
{
String[] entry = pair.split("="); //split the pairs to get key and value
map.put(entry[0].trim(), entry[1].trim()); //add them to the hashmap and trim whitespaces
}
For example you can switch
value = value.substring(1, value.length()-1);
to
value = StringUtils.substringBetween(value, "{", "}");
if you are using StringUtils
which is contained in apache.commons.lang
package.
As Brad Wilson states in his answer here:
ModelState.IsValid tells you if any model errors have been added to ModelState.
The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.
Try using :-
if (!ModelState.IsValid)
{
var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));
// Breakpoint, Log or examine the list with Exceptions.
}

From IEEE floating-point exceptions in C++ :
This page will answer the following questions.
- My program just printed out 1.#IND or 1.#INF (on Windows) or nan or inf (on Linux). What happened?
- How can I tell if a number is really a number and not a NaN or an infinity?
- How can I find out more details at runtime about kinds of NaNs and infinities?
- Do you have any sample code to show how this works?
- Where can I learn more?
These questions have to do with floating point exceptions. If you get some strange non-numeric output where you're expecting a number, you've either exceeded the finite limits of floating point arithmetic or you've asked for some result that is undefined. To keep things simple, I'll stick to working with the double floating point type. Similar remarks hold for float types.
Debugging 1.#IND, 1.#INF, nan, and inf
If your operation would generate a larger positive number than could be stored in a double, the operation will return 1.#INF on Windows or inf on Linux. Similarly your code will return -1.#INF or -inf if the result would be a negative number too large to store in a double. Dividing a positive number by zero produces a positive infinity and dividing a negative number by zero produces a negative infinity. Example code at the end of this page will demonstrate some operations that produce infinities.
Some operations don't make mathematical sense, such as taking the square root of a negative number. (Yes, this operation makes sense in the context of complex numbers, but a double represents a real number and so there is no double to represent the result.) The same is true for logarithms of negative numbers. Both sqrt(-1.0) and log(-1.0) would return a NaN, the generic term for a "number" that is "not a number". Windows displays a NaN as -1.#IND ("IND" for "indeterminate") while Linux displays nan. Other operations that would return a NaN include 0/0, 0*8, and 8/8. See the sample code below for examples.
In short, if you get 1.#INF or inf, look for overflow or division by zero. If you get 1.#IND or nan, look for illegal operations. Maybe you simply have a bug. If it's more subtle and you have something that is difficult to compute, see Avoiding Overflow, Underflow, and Loss of Precision. That article gives tricks for computing results that have intermediate steps overflow if computed directly.

The short answer:
echo "some data for the file" >> fileName
However, echo
doesn't deal with end of line characters (EOFs) in an ideal way. So, if you're gonna append more than one line, do it with printf
:
printf "some data for the file\nAnd a new line" >> fileName
The >>
and >
operators are very useful for redirecting output of commands, they work with multiple other bash commands.

If you are looking to style a file input element, look at open file dialog box in javascript. If you are looking to grab the files associated with a file input element, you must do something like this:
inputElement.onchange = function(event) {
var fileList = inputElement.files;
//TODO do something with fileList.
}
See this MDN article for more info on the FileList
type.
Note that the code above will only work in browsers that support the File API. For IE9 and earlier, for example, you only have access to the file name. The input element has no files
property in non-File API browsers.

I had a problem with a CSV that contains fields with a quote character in them, so using the TextFieldParser, I came up with the following:
private static string[] parseCSVLine(string csvLine)
{
using (TextFieldParser TFP = new TextFieldParser(new MemoryStream(Encoding.UTF8.GetBytes(csvLine))))
{
TFP.HasFieldsEnclosedInQuotes = true;
TFP.SetDelimiters(",");
try
{
return TFP.ReadFields();
}
catch (MalformedLineException)
{
StringBuilder m_sbLine = new StringBuilder();
for (int i = 0; i < TFP.ErrorLine.Length; i++)
{
if (i > 0 && TFP.ErrorLine[i]== '"' &&(TFP.ErrorLine[i + 1] != ',' && TFP.ErrorLine[i - 1] != ','))
m_sbLine.Append("\"\"");
else
m_sbLine.Append(TFP.ErrorLine[i]);
}
return parseCSVLine(m_sbLine.ToString());
}
}
}
A StreamReader is still used to read the CSV line by line, as follows:
using(StreamReader SR = new StreamReader(FileName))
{
while (SR.Peek() >-1)
myStringArray = parseCSVLine(SR.ReadLine());
}
The trick here is that the ToolTip control is an extender control, which means that it will extend the set of properties for other controls on the form. Behind the scenes this is achieved by generating code like in Svetlozar's answer. There are other controls working in the same manner (such as the HelpProvider
).

overflow: auto;
/* width property only required if you want to support IE6 */
width: 100%;
}
.outer-center {
float: right;
right: 50%;
position: relative;
}
.inner-center {
float: right;
right: -50%;
position: relative;
}
The reason, why it's better without div.clear
(apart that it feels wrong to have an empty element) is Firefox'es overzealous margin assignment.
If, for example, you have this html:
<div class="product_container">
<div class="outer-center">
<div class="product inner-center">
</div>
</div>
<div style="clear: both;"></div>
</div>
<p style="margin-top: 11px;">Some text</p>
then, in Firefox (8.0 at the point of writing), you will see 11px
margin before product_container
. What's worse, is that you will get a vertical scroll bar for the whole page, even if the content fits nicely into the screen dimensions.
For updates, need to call setTransactionSuccessfull for changes to get committed like so:
db.beginTransaction();
try {
db.update(...)
db.setTransactionSuccessfull(); // changes get rolled back if this not called
} finally {
db.endTransaction(); // commit or rollback
}
None of the above worked for my table. I have a table with an unsigned integer as the primary key with values ranging from 0 to 31543. Currently there are over 19 thousand records. I had to modify the column to AUTO_INCREMENT
(MODIFY COLUMN
'id'INTEGER UNSIGNED NOT NULL AUTO_INCREMENT
) and set the seed(AUTO_INCREMENT = 31544
) in the same statement.
ALTER TABLE `'TableName'` MODIFY COLUMN `'id'` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, AUTO_INCREMENT = 31544;
The only thing you have to do is to add in the cshtml file, in the head, the following line:
@Styles.Render("~/Content/Main.css")
The entire head will look somethink like that:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>HTML Page</title>
@Styles.Render("~/Content/main.css")
</head>
Hope it helps!!
If you're looking for something more straight forward to implement (and it doesn't include pie/donut charts) then I recommend WilliamChart. Specially if motion takes an important role in your app design. In other hand if you want featured charts, then go for MPAndroidChart.
Checkout the .SaveAs()
method in Excel object.
wbWorkbook.SaveAs("c:\yourdesiredFilename.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSV)
Or following:
public static void SaveAs()
{
Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.ApplicationClass();
Microsoft.Office.Interop.Excel.Workbook wbWorkbook = app.Workbooks.Add(Type.Missing);
Microsoft.Office.Interop.Excel.Sheets wsSheet = wbWorkbook.Worksheets;
Microsoft.Office.Interop.Excel.Worksheet CurSheet = (Microsoft.Office.Interop.Excel.Worksheet)wsSheet[1];
Microsoft.Office.Interop.Excel.Range thisCell = (Microsoft.Office.Interop.Excel.Range)CurSheet.Cells[1, 1];
thisCell.Value2 = "This is a test.";
wbWorkbook.SaveAs(@"c:\one.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
wbWorkbook.SaveAs(@"c:\two.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSVWindows, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
wbWorkbook.Close(false, "", true);

Odd reasoning for me - I had deleted the project and pulled from repo. Because of this, the build/ files were missing.
Here is how you would construct your query for this type of requirement.
select ID,Item_Name,max(Flavor) as Flavor,max(Extra_Cheese) as Extra_Cheese
from (select i.*,
case when o.Option_Number=43 then o.value else null end as Flavor,
case when o.Option_Number=44 then o.value else null end as Extra_Cheese
from Ordered_Item i,Ordered_Options o) a
group by ID,Item_Name;
You basically "case out" each column using case when
, then select the max()
for each of those columns using group by
for each intended item.
I had same problem and its very strange. If you believe you are doing all good than follow this: Some times there is confusion about user for the EC2 instance!! Some times you get ec2-user, ubuntu, centos etc. So check your username for the machie!!
Login with root user
ssh -i yourkey.pem (400 permission) root@<ip>
It will throw error and will give you the available username. then login with that user.
In POJS, you add one listener at a time. It is not common to add the same listener for two different events on the same element. You could write your own small function to do the job, e.g.:
/* Add one or more listeners to an element
** @param {DOMElement} element - DOM element to add listeners to
** @param {string} eventNames - space separated list of event names, e.g. 'click change'
** @param {Function} listener - function to attach for each event as a listener
*/
function addListenerMulti(element, eventNames, listener) {
var events = eventNames.split(' ');
for (var i=0, iLen=events.length; i<iLen; i++) {
element.addEventListener(events[i], listener, false);
}
}
addListenerMulti(window, 'mousemove touchmove', function(){…});
Hopefully it shows the concept.
Edit 2016-02-25
Dalgard's comment caused me to revisit this. I guess adding the same listener for multiple events on the one element is more common now to cover the various interface types in use, and Isaac's answer offers a good use of built–in methods to reduce the code (though less code is, of itself, not necessarily a bonus). Extended with ECMAScript 2015 arrow functions gives:
function addListenerMulti(el, s, fn) {
s.split(' ').forEach(e => el.addEventListener(e, fn, false));
}
A similar strategy could add the same listener to multiple elements, but the need to do that might be an indicator for event delegation.
No, it cannot be done. Either you can use a dictionary, or you can try hashing different values until you get the hash that you are seeking. But it cannot be "decrypted".
Similar to @Rhusfer answer I wrote this. In case you have a group of EditText
s and want to concatenate their values, you can write:
listOf(edit_1, edit_2, edit_3, edit_4).joinToString(separator = "") { it.text.toString() }
If you want to concatenate Map
, use this:
map.entries.joinToString(separator = ", ")
To concatenate Bundle
, use
bundle.keySet().joinToString(", ") { key -> "$key=${bundle[key]}" }
It sorts keys in alphabetical order.
Example:
val map: MutableMap<String, Any> = mutableMapOf("price" to 20.5)
map += "arrange" to 0
map += "title" to "Night cream"
println(map.entries.joinToString(separator = ", "))
// price=20.5, arrange=0, title=Night cream
val bundle = bundleOf("price" to 20.5)
bundle.putAll(bundleOf("arrange" to 0))
bundle.putAll(bundleOf("title" to "Night cream"))
val bundleString =
bundle.keySet().joinToString(", ") { key -> "$key=${bundle[key]}" }
println(bundleString)
// arrange=0, price=20.5, title=Night cream
Well, in my case the problem had a different cause, the Windows path Length Check this.
I was installing a library on a virtualenv
which made the path get longer. As the library was installed, it created some files under site-packages
. This made the path exceed Windows limit throwing this error.
Hope it helps someone =)
You can use ES6 to import package.json to retrieve version number and output the version on console.
import {name as app_name, version as app_version} from './path/to/package.json';
console.log(`App ---- ${app_name}\nVersion ---- ${app_version}`);
In my case I got this message because there's a special char (&) in my connectionstring, remove it then everything's good.
Cheers
You can put overflow:hidden
onto the property with the text indent, and that dotted line, that spans out of the page, will dissapear.
I've seen a couple of posts about removing outlines all together. Be careful when doing this as you could lower the accessibility of the site.
a:active { outline: none; }
I personally would use this attribute only, as if the :hover
attribute has the same css properties it will prevent the outlines showing for people who are using the keyboard for navigation.
Hope this solves your problem.
You can use top_n
df %>% group_by(A, B) %>% top_n(n=1)
This will rank by the last column (value
) and return the top n=1
rows.
Currently, you can't change the this default without causing an error (See https://github.com/hadley/dplyr/issues/426)
Android doesn't allow you to set custom fonts from the XML layout. Instead, you must bundle the specific font file in your app's assets folder, and set it programmatically. Something like:
TextView textView = (TextView) findViewById(<your TextView ID>);
Typeface typeFace = Typeface.createFromAsset(getAssets(), "<file name>");
textView.setTypeface(typeFace);
Note that you can only run this code after setContentView() has been called. Also, only some fonts are supported by Android, and should be in a .ttf (TrueType)
or .otf (OpenType)
format. Even then, some fonts may not work.
This is a font that definitely works on Android, and you can use this to confirm that your code is working in case your font file isn't supported by Android.
Android O Update: This is now possible with XML in Android O, based on Roger's comment.

Seems like only real solutions today revolve around scaling out or sharding. All modern databases (NoSQLs as well as NewSQLs) support horizontal scaling right out of the box, at the database layer, without the need for the application to have sharding code or something.
Unfortunately enough, for the trusted good-old MySQL, sharding is not provided "out of the box". ScaleBase (disclaimer: I work there) is a maker of a complete scale-out solution an "automatic sharding machine" if you like. ScaleBae analyzes your data and SQL stream, splits the data across DB nodes, and aggregates in runtime – so you won’t have to! And it's free download.
Don't get me wrong, NoSQLs are great, they're new, new is more choice and choice is always good!! But choosing NoSQL comes with a price, make sure you can pay it...
You can see here some more data about MySQL, NoSQL...: http://www.scalebase.com/extreme-scalability-with-mongodb-and-mysql-part-1-auto-sharding
Hope that helped.
I am talking here from a theoretical point of view; I have not tried BitLocker.
BitLocker uses AES encryption with a 128-bit key. On a Core2 machine, clocked at 2.53 GHz, encryption speed should be about 110 MB/s, using one core. The two cores could process about 220 MB/s, assuming perfect data transfer and core synchronization with no overhead, and that nothing requires the CPU in the same time (that one hell of an assumption, actually). The X25-M G2 is announced at 250 MB/s read bandwidth (that's what the specs say), so, in "ideal" conditions, BitLocker necessarily involves a bit of a slowdown.
However read bandwidth is not that important. It matters when you copy huge files, which is not something that you do very often. In everyday work, access time is much more important: as a developer, you create, write, read and delete many files, but they are all small (most of them are much smaller than one megabyte). This is what makes SSD "snappy". Encryption does not impact access time. So my guess is that any performance degradation will be negligible(*).
(*) Here I assume that Microsoft's developers did their job properly.
None of the screen
commands were killing or reattaching the screen for me. Any screen
command would just hang. I found another approach.
Each running screen has a file associated with it in:
/var/run/screen/S-{user_name}
The files in that folder will match the names of the screens when running the screen -list
. If you delete the file, it kills the associated running screen (detached or attached).
I was experiencing this same symptom - 404 on woff files in Chrome - and was running an application on a Windows Server with IIS 6.
If you are in the same situation you can fix it by doing the following:
"Simply add the following MIME type declarations via IIS Manager (HTTP Headers tab of website properties): .woff application/x-woff"
Update: according to MIME Types for woff fonts and Grsmto the actual MIME type is application/x-font-woff (for Chrome at least). x-woff will fix Chrome 404s, x-font-woff will fix Chrome warnings.
As of 2017: Woff fonts have now been standardised as part of the RFC8081 specification to the mime type font/woff
and font/woff2
.
Thanks to Seb Duggan: http://sebduggan.com/posts/serving-web-fonts-from-iis
You can also add the MIME types in the web config:
<system.webServer>
<staticContent>
<remove fileExtension=".woff" /> <!-- In case IIS already has this mime type -->
<mimeMap fileExtension=".woff" mimeType="font/woff" />
</staticContent>
</system.webServer>

Instead of ((t[1])/length) * t[1] += string
, you should use string += ((t[1])/length) * t[1]
. (The other syntax issue - int is not iterable
- will be your exercise to figure out.)
Use get_the_category()
like this:
<?php
foreach((get_the_category()) as $category) {
echo $category->cat_name . ' ';

It returns a list because a post can have more than one category.
The documentation also explains how to do this from outside the loop.

You must define Full-Text-Index
on all tables in database where you require to use a query with CONTAINS
which will take sometime.
Instead you can use the LIKE
which will give you instant results without the need to adjust any settings for the tables.
Example:
SELECT * FROM ChartOfAccounts WHERE AccountName LIKE '%Tax%'
The same result obtained with CONTAINS
can be obtained with LIKE
.
Here i have written a logic try it :)
public class palindromeClass{
public static String longestPalindromeString(String in) {
char[] input = in.toCharArray();
int longestPalindromeStart = 0;
int longestPalindromeEnd = 0;
for (int mid = 0; mid < input.length; mid++) {
// for odd palindrome case like 14341, 3 will be the mid
int left = mid-1;
int right = mid+1;
// we need to move in the left and right side by 1 place till they reach the end
while (left >= 0 && right < input.length) {
// below check to find out if its a palindrome
if (input[left] == input[right]) {
// update global indexes only if this is the longest one till now
if (right - left > longestPalindromeEnd
- longestPalindromeStart) {
longestPalindromeStart = left;
longestPalindromeEnd = right;
}
}
else
break;
left--;
right++;
}
// for even palindrome, we need to have similar logic with mid size 2
// for that we will start right from one extra place
left = mid;
right = mid + 1;// for example 12333321 when we choose 33 as mid
while (left >= 0 && right < input.length)
{
if (input[left] == input[right]) {
if (right - left > longestPalindromeEnd
- longestPalindromeStart) {
longestPalindromeStart = left;
longestPalindromeEnd = right;

If you use jQuery you can write:
$( _checkbox ).click( function( e ){ /*process event here*/ } )

SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;
END
$$ LANGUAGE plpgsql;
Call:
SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)
You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.
The aggregate function count()
returns bigint
, but you had rowcount
defined as integer
, so you need an explicit cast ::int
to make this work
I use dollar quoting to avoid quoting hell.
However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.
Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)
The query itself seems rather odd, btw. But that's beside the point here.
You are searching for a multimap, and indeed both commons-collections and Guava have several implementations for that. Multimaps allow for multiple keys by maintaining a collection of values per key, i.e. you can put a single object into the map, but you retrieve a collection.
If you can use Java 5, I would prefer Guava's Multimap
as it is generics-aware.

The purpose of .iteritems()
was to use less memory space by yielding one result at a time while looping. I am not sure why Python 3 version does not support iteritems()
though it's been proved to be efficient than .items()
If you want to include a code that supports both the PY version 2 and 3,
try:
iteritems
except NameError:
iteritems = items
This can help if you deploy your project in some other system and you aren't sure about the PY version.
You use separator when you are building a file path. So in unix the separator is /
. So if you wanted to build the unix path /var/temp
you would do it like this:
String path = File.separator + "var"+ File.separator + "temp"
You use the pathSeparator
when you are dealing with a list of files like in a classpath. For example, if your app took a list of jars as argument the standard way to format that list on unix is: /path/to/jar1.jar:/path/to/jar2.jar:/path/to/jar3.jar
So given a list of files you would do something like this:
String listOfFiles = ...
String[] filePaths = listOfFiles.split(File.pathSeparator);
You should stop the submit procedure by returning false on the onsubmit callback.
<script>
function checkRegistration(){
if(!form_valid){
alert('Given data is not correct');
return false;
}
return true;
}
</script>
<form onsubmit="return checkRegistration()"...
Here you have a fully working example. The form will submit only when you write google into input, otherwise it will return an error:
<script>
function checkRegistration(){
var form_valid = (document.getElementById('some_input').value == 'google');
if(!form_valid){
alert('Given data is incorrect');
return false;
}
return true;
}
</script>
<form onsubmit="return checkRegistration()" method="get" action="http://google.com">
Write google to go to google...<br/>
<input type="text" id="some_input" value=""/>
<input type="submit" value="google it"/>
</form>
$("td:contains('c')").html("new");
or, more precisely $("#table_headers td:contains('c')").html("new");

}
mentions YAML line continuations.
As an example (tried with ansible 2.0.0.2):
---
- hosts: all
tasks:
- name: multiline shell command
shell: >
ls --color
/home
register: stdout
- name: debug output
debug: msg={{ stdout }}
The shell command is collapsed into a single line, as in ls --color /home
You can use the date() function:
date('w'); // day of week
or
date('l'); // dayname
Example function to get the day nr.:
function getWeekday($date) {
return date('w', strtotime($date));
}
echo getWeekday('2012-10-11'); // returns 4
I highly recommend the book "Pro Git" by Scott Chacon. Take time and really read it, while exploring an actual git repo as you do.
HEAD: the current commit your repo is on. Most of the time HEAD
points to the latest commit in your current branch, but that doesn't have to be the case. HEAD
really just means "what is my repo currently pointing at".
In the event that the commit HEAD
refers to is not the tip of any branch, this is called a "detached head".
master: the name of the default branch that git creates for you when first creating a repo. In most cases, "master" means "the main branch". Most shops have everyone pushing to master, and master is considered the definitive view of the repo. But it's also common for release branches to be made off of master for releasing. Your local repo has its own master branch, that almost always follows the master of a remote repo.
origin: the default name that git gives to your main remote repo. Your box has its own repo, and you most likely push out to some remote repo that you and all your coworkers push to. That remote repo is almost always called origin, but it doesn't have to be.
HEAD
is an official notion in git. HEAD
always has a well-defined meaning. master
and origin
are common names usually used in git, but they don't have to be.
Launch4j works on both Windows and Linux/Mac. But if you're running Linux/Mac, there is a way to embed your jar into a shell script that performs the autolaunch for you, so you have only one runnable file:
exestub.sh:
#!/bin/sh
MYSELF=`which "$0" 2>/dev/null`
[ $? -gt 0 -a -f "$0" ] && MYSELF="./$0"
JAVA_OPT=""
PROG_OPT=""
# Parse options to determine which ones are for Java and which ones are for the Program
while [ $# -gt 0 ] ; do
case $1 in
-Xm*) JAVA_OPT="$JAVA_OPT $1" ;;
-D*) JAVA_OPT="$JAVA_OPT $1" ;;
*) PROG_OPT="$PROG_OPT $1" ;;
esac
shift
done
exec java $JAVA_OPT -jar $MYSELF $PROG_OPT
Then you create your runnable file from your jar:
$ cat exestub.sh myrunnablejar.jar > myrunnable
$ chmod +x myrunnable
It works the same way launch4j works: because a jar has a zip format, which header is located at the end of the file. You can have any header you want (either binary executable or, like here, shell script) and run java -jar <myexe>
, as <myexe>
is a valid zip/jar file.
I would like to compliment Ram Narasimhans answer with some tips I found on an Excel blog
Non-uniformly distributed data can be plotted in excel in
Just like Ram Narasimhan suggested, to have the points centered you will want the mid point but you don't need to move to a numeric format, you can stay in the time format.
1- Add the center point to your data series
+---------------+-------+------+
| Time | Time | Freq |
+---------------+-------+------+
| 08:00 - 09:00 | 08:30 | 12 |
| 09:00 - 10:00 | 09:30 | 13 |
| 10:00 - 11:00 | 10:30 | 10 |
| 13:00 - 14:00 | 13:30 | 5 |
| 14:00 - 15:00 | 14:30 | 14 |
+---------------+-------+------+
2- Create a Scatter Plot
3- Excel allows you to specify time values for the axis options. Time values are a parts per 1 of a 24-hour day. Therefore if we want to 08:00 to 15:00, then we Set the Axis options to:
Alternative Display:
To be able to represent these points as bars instead of just point we need to draw disjoint lines. Here is a way to go about getting this type of chart.
1- You're going to need to add several rows where we draw the line and disjoint the data
+-------+------+
| Time | Freq |
+-------+------+
| 08:30 | 0 |
| 08:30 | 12 |
| | |
| 09:30 | 0 |
| 09:30 | 13 |

2- Plot an X Y (Scatter) Chart with Lines.
3- Now you can tweak the data series to have a fatter line, no markers, etc.. to get a bar/column type chart with non-uniformly distributed data.

I don't know why but you have to add a setTimeout with at least for me 200ms:
setTimeout( function() {$("#DIV_ID").scrollTop(0)}, 200 );
Tested with Firefox / Chrome / Edge.
Right click on Sample.java file and delete it. Now go to File -> New -> Class , enter name of program (i.e. hello) , click on finish . It will create file hello.java. Enter source code of program and finallly press ctrl + F11
I agree with Charles Duffy that a proper XML parser is the right way to go.
But as to what's wrong with your sed
command (or did you do it on purpose?).
$data
was not quoted, so $data
is subject to shell's word splitting, filename expansion among other things. One of the consequences being that the spacing in the XML snippet is not preserved.So given your specific XML structure, this modified sed
command should work
title=$(sed -ne '/title/{s/.*<title>\(.*\)<\/title>.*/\1/p;q;}' <<< "$data")
Basically for the line that contains title
, extract the text between the tags, then quit (so you don't extract the 2nd <title>
)
Using $emit and $broadcast, (as mentioned by walv in the comments above)
To fire an event upwards (from child to parent)
$scope.$emit('myTestEvent', 'Data to send');
To fire an event downwards (from parent to child)
$scope.$broadcast('myTestEvent', {
someProp: 'Sending you some data'
});
and finally to listen
$scope.$on('myTestEvent', function (event, data) {
console.log(data);
});

How would I accomplish the nextsibling and is there an easier way of doing this?
You may use:
tr/td[@class='name']/following-sibling::td
but I'd rather use directly:
tr[td[@class='name'] ='Brand']/td[@class='desc']
This assumes that:
The context node, against which the XPath expression is evaluated is the parent of all tr
elements -- not shown in your question.
Each tr
element has only one td
with class
attribute valued 'name'
and only one td
with class
attribute valued 'desc'
.
1· Do I need these DLL's?
It depends since Dependency Walker is a little bit out of date and may report the wrong dependency.
- Where can I get them?
most dlls can be found at https://www.dll-files.com
I believe they are supposed to located in C:\Windows\System32\Wer.dll and C:\Program Files\Internet Explorer\Ieshims.dll
For me leshims.dll
can be placed at C:\Windows\System32\
. Context: windows 7 64bit.
What means about isKindOfClass in Apple Documentation
Be careful when using this method on objects represented by a class cluster. Because of the nature of class clusters, the object you get back may not always be the type you expected. If you call a method that returns a class cluster, the exact type returned by the method is the best indicator of what you can do with that object. For example, if a method returns a pointer to an NSArray object, you should not use this method to see if the array is mutable, as shown in the following code:
// DO NOT DO THIS!
if ([myArray isKindOfClass:[NSMutableArray class]])
{
// Modify the object
}
If you use such constructs in your code, you might think it is alright to modify an object that in reality should not be modified. Doing so might then create problems for other code that expected the object to remain unchanged.
I think the answer depends on which features of stored procedures you need to use.
Stored procedures returning a result set can be run using Query
; stored procedures which don't return a result set can be run using Execute
- in both cases (using EXEC <procname>
) as the SQL command (plus input parameters as necessary). See the documentation for more details.
As of revision 2d128ccdc9a2 there doesn't appear to be native support for OUTPUT
parameters; you could add this, or alternatively construct a more complex Query
command which declared TSQL variables, executed the SP collecting OUTPUT
parameters into the local variables and finallyreturned them in a result set:
DECLARE @output int
EXEC <some stored proc> @i = @output OUTPUT
SELECT @output AS output1
Here is one way to calculate log return using .shift()
. And the result is similar to but not the same as the gross return calculated by pct_change()
. Can you upload a copy of your sample data (dropbox share link) to reproduce the inconsistency you saw?
import pandas as pd
import numpy as np
np.random.seed(0)
df = pd.DataFrame(100 + np.random.randn(100).cumsum(), columns=['price'])
df['pct_change'] = df.price.pct_change()
df['log_ret'] = np.log(df.price) - np.log(df.price.shift(1))
Out[56]:
price pct_change log_ret

First create UIImageView then add image in UIImageView .
var imageView : UIImageView
imageView = UIImageView(frame:CGRectMake(10, 50, 100, 300));
imageView.image = UIImage(named:"image.jpg")
self.view.addSubview(imageView)
No IEnumerable is an interface, you can't create instance of interface
you can do something like this
IEnumerable<object> a = new object[0];
If you want to get the key name of myVar
object then you can use Object.keys()
for this purpose.
var result = Object.keys(myVar);
alert(result[0]) // result[0] alerts typeA
It's a sort of dummy table with a single record used for selecting when you're not actually interested in the data, but instead want the results of some system function in a select statement:
e.g. select sysdate from dual;
click appears to be blocking? - here's another way to wait if you're using WebDriverJS:
driver.findElement(webdriver.By.name('mybutton')).click().then(function(){
driver.getPageSource().then(function(source) {
console.log(source);
});
});
The code above waits after the button is clicked for the next page to load and then grabs the source of the next page.
It means there is a problem with the build path in your project. If it is an android project then it mostly means the target value specified in project.properties file cannot be found. This can also be caused because of other kinds of built problems. But it is shown mostly for built problems only. See here for more details. It is about built error decorater seen in eclipse.
An extract from that page:
Build path problems are sometimes easy to miss among other problems in a project. The Package Explorer and Project Explorer views now show a new decorator on Java projects and working sets that contain build path errors:
The concrete errors can be seen in the Problems view, and if you open the view menu and select Group By > Java Problem Type, they all show up in the Build Path category:
If you really need to get it back into an array I find it easiest to convert the array
to a list
, expand the list then convert it back to an array
.
string[] myArray = new string[1] {"Element One"};
// Convert it to a list
List<string> resizeList = myArray.ToList();
// Add some elements
resizeList.Add("Element Two");
// Back to an array
myArray = resizeList.ToArray();
// myArray has grown to two elements.
You can try the border-spacing property. That should do what you want. But you may want to see this answer.
To add to Reed Copsey's answer about using Task.FromResult
, you can improve performance even more if you cache the already completed task since all instances of completed tasks are the same:
public static class TaskExtensions
{
public static readonly Task CompletedTask = Task.FromResult(false);
}
With TaskExtensions.CompletedTask
you can use the same instance throughout the entire app domain.
The latest version of the .Net Framework (v4.6) adds just that with the Task.CompletedTask
static property
Task completedTask = Task.CompletedTask;
I've seen the same thing in firefox, css transform scaled transparent png's looking very rough.
I noticed that when they previously had a background color set the quality was much better, so I tried setting an RGBA background with as low an opacity value as possible.
background:rgba(255,255,255,0.001);
This worked for me, give it a try.

You just need to set the userTrackingMode of the MKMapView. If you only want to display and track the user location and implement the same behaviour as the Apple Maps app uses, there is no reason for writing additional code.
mapView.userTrackingMode = .follow

Combining and organizing all the current answers into one answer, then adding my own research:
Brief summary of Microsoft gadget development:
What are they written in? Windows Vista/Seven gadgets are developed in a mix of XML, HTML, CSS, and some IE scripting language. It is also possible to use C# with the latest release of Script#.
How are they packaged/deployed? The actual gadgets are stored in *.gadget files, which are simply the text source files listed above compressed into a single zip file.
Useful references for gadget development:
where do I start? Good introductory references to Windows Vista/Seven gadget development:
If you are willing to use offline resources, this book appears to be an excellent resource:
What do I need to know? Some other useful references; not necessarily instructional
Update: Well, this has proven to be a popular answer~ Sharing my own recent experience with Windows 7 gadget development:
Perhaps the easiest way to get started with Windows 7 gadget development is to modify a gadget that has already been developed. I recently did this myself because I wanted a larger clock gadget. Unable to find any, I tinkered with a copy of the standard Windows clock gadget until it was twice as large. I recommend starting with the clock gadget because it is fairly small and well-written. Here is the process I used:
C:\Program Files\Windows Sidebar\Gadgets\Clock.Gadget\
<name>Clock</name>
This is the name that will be displayed in the "Gadgets Gallery" window.%LOCALAPPDATA%\Microsoft\Windows Sidebar\
)Although this an old post, I am sharing another working example.
"COLUMN COUNT AS WELL AS EACH COLUMN DATATYPE MUST MATCH WHEN 'UNION' OR 'UNION ALL' IS USED"
Let us take an example:
In SQL if we write - SELECT 'column1', 'column2' (NOTE: remember to specify names in quotes) In a result set, it will display empty columns with two headers - column1 and column2
I had seven columns with few different datatypes in SQL. I.e. uniqueidentifier, datetime, nvarchar
My task was to retrieve comma separated result set with column header. So that when I export the data to CSV I have comma separated rows with first row as header and has respective column names.
SELECT CONVERT(NVARCHAR(36), 'Event ID') + ', ' +
'Last Name' + ', ' +
'First Name' + ', ' +
'Middle Name' + ', ' +
CONVERT(NVARCHAR(36), 'Document Type') + ', ' +
'Event Type' + ', ' +
CONVERT(VARCHAR(23), 'Last Updated', 126)
UNION ALL
SELECT CONVERT(NVARCHAR(36), inspectionid) + ', ' +
individuallastname + ', ' +
individualfirstname + ', ' +
individualmiddlename + ', ' +
CONVERT(NVARCHAR(36), documenttype) + ', ' +
'I' + ', ' +
CONVERT(VARCHAR(23), modifiedon, 126)
FROM Inspection
Above, columns 'inspectionid' & 'documenttype' has uniqueidentifer
datatype and so applied CONVERT(NVARCHAR(36))
. column 'modifiedon' is datetime and so applied CONVERT(NVARCHAR(23), 'modifiedon', 126)
.
Parallel to above 2nd SELECT
query matched 1st SELECT
query as per datatype of each column.
Shuffle any number of arrays together, in-place, using only NumPy.
import numpy as np
def shuffle_arrays(arrays, set_seed=-1):
"""Shuffles arrays in-place, in the same order, along axis=0
Parameters:
-----------
arrays : List of NumPy arrays.
set_seed : Seed value if int >= 0, else seed is random.
"""
assert all(len(arr) == len(arrays[0]) for arr in arrays)
seed = np.random.randint(0, 2**(32 - 1) - 1) if set_seed < 0 else set_seed
for arr in arrays:
rstate = np.random.RandomState(seed)
rstate.shuffle(arr)
And can be used like this
a = np.array([1, 2, 3, 4, 5])
b = np.array([10,20,30,40,50])
c = np.array([[1,10,11], [2,20,22], [3,30,33], [4,40,44], [5,50,55]])
shuffle_arrays([a, b, c])
A few things to note:
After the shuffle, the data can be split using np.split
or referenced using slices - depending on the application.
After searching a bit about the method to open the existing sheet in xlxs, i discovered
existingWorksheet = wb.get_worksheet_by_name('Your Worksheet name goes here...')
existingWorksheet.write_row(0,0,'xyz')
You can now append/write any data to the open worksheet. I hope it helps. Thanks
May be?
