If useful, try this:
BufferedImage imgBuffer = ImageIO.read(new File("c:\\image.bmp"));
byte[] pixels = (byte[])imgBuffer.getRaster().getDataElements(0, 0, imgBuffer.getWidth(), imgBuffer.getHeight(), null);
BufferedImage in = ImageIO.read(img);
BufferedImage newImage = new BufferedImage(
in.getWidth(), in.getHeight(), BufferedImage.TYPE_INT_ARGB);
Graphics2D g = newImage.createGraphics();
g.drawImage(in, 0, 0, null);
g.dispose();
Unfortunately the performance of getScaledInstance() is very poor if not problematic.
The alternative approach is to create a new BufferedImage and and draw a scaled version of the original on the new one.
BufferedImage resized = new BufferedImage(newWidth, newHeight, original.getType());
Graphics2D g = resized.createGraphics();
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.drawImage(original, 0, 0, newWidth, newHeight, 0, 0, original.getWidth(),
original.getHeight(), null);
g.dispose();
newWidth,newHeight indicate the new BufferedImage size and have to be properly calculated. In case of factor scaling:
int newWidth = new Double(original.getWidth() * widthFactor).intValue();
int newHeight = new Double(original.getHeight() * heightFactor).intValue();
EDIT: Found the article illustrating the performance issue: The Perils of Image.getScaledInstance()
BufferedImage is a(n) Image, so the implicit cast that you're doing in the second line is able to be compiled directly. If you knew an Image was really a BufferedImage, you would have to cast it explicitly like so:
Image image = ImageIO.read(new File(file));
BufferedImage buffered = (BufferedImage) image;
Because BufferedImage extends Image, it can fit in an Image container. However, any Image can fit there, including ones that are not a BufferedImage, and as such you may get a ClassCastException at runtime if the type does not match, because a BufferedImage cannot hold any other type unless it extends BufferedImage.
As a one liner:
ImageIO.write(Scalr.resize(ImageIO.read(...), 150));
if r, g, b = 3 integer values from 0 to 255 for each color
then
rgb = 65536 * r + 256 * g + b;
the single rgb value is the composite value of r,g,b combined for a total of 16777216 possible shades.
One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:
final float FACTOR = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);
That should do the trick without casting.
The answer above didn't work for me, this worked:
psql db_development < postgres_db.dump
There are two ways to approach this problem: numerically and symbolically.
To solve it numerically, you have to first encode it as a "runnable" function - stick a value in, get a value out. For example,
def my_function(x):
return 2*x + 6
It is quite possible to parse a string to automatically create such a function; say you parse 2x + 6
into a list, [6, 2]
(where the list index corresponds to the power of x - so 6*x^0 + 2*x^1). Then:
def makePoly(arr):
def fn(x):
return sum(c*x**p for p,c in enumerate(arr))
return fn
my_func = makePoly([6, 2])
my_func(3) # returns 12
You then need another function which repeatedly plugs an x-value into your function, looks at the difference between the result and what it wants to find, and tweaks its x-value to (hopefully) minimize the difference.
def dx(fn, x, delta=0.001):
return (fn(x+delta) - fn(x))/delta
def solve(fn, value, x=0.5, maxtries=1000, maxerr=0.00001):
for tries in xrange(maxtries):
err = fn(x) - value
if abs(err) < maxerr:
return x
slope = dx(fn, x)
x -= err/slope
raise ValueError('no solution found')
There are lots of potential problems here - finding a good starting x-value, assuming that the function actually has a solution (ie there are no real-valued answers to x^2 + 2 = 0), hitting the limits of computational accuracy, etc. But in this case, the error minimization function is suitable and we get a good result:
solve(my_func, 16) # returns (x =) 5.000000000000496
Note that this solution is not absolutely, exactly correct. If you need it to be perfect, or if you want to try solving families of equations analytically, you have to turn to a more complicated beast: a symbolic solver.
A symbolic solver, like Mathematica or Maple, is an expert system with a lot of built-in rules ("knowledge") about algebra, calculus, etc; it "knows" that the derivative of sin is cos, that the derivative of kx^p is kpx^(p-1), and so on. When you give it an equation, it tries to find a path, a set of rule-applications, from where it is (the equation) to where you want to be (the simplest possible form of the equation, which is hopefully the solution).
Your example equation is quite simple; a symbolic solution might look like:
=> LHS([6, 2]) RHS([16])
# rule: pull all coefficients into LHS
LHS, RHS = [lh-rh for lh,rh in izip_longest(LHS, RHS, 0)], [0]
=> LHS([-10,2]) RHS([0])
# rule: solve first-degree poly
if RHS==[0] and len(LHS)==2:
LHS, RHS = [0,1], [-LHS[0]/LHS[1]]
=> LHS([0,1]) RHS([5])
and there is your solution: x = 5.
I hope this gives the flavor of the idea; the details of implementation (finding a good, complete set of rules and deciding when each rule should be applied) can easily consume many man-years of effort.
Here is my solution for behavior like in @followben answer, but without loss with slow start (when dy is 0)
@property (assign, nonatomic) BOOL isFinding;
@property (assign, nonatomic) CGFloat previousOffset;
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
self.isFinding = YES;
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
if (self.isFinding) {
if (self.previousOffset == 0) {
self.previousOffset = self.tableView.contentOffset.y;
} else {
CGFloat diff = self.tableView.contentOffset.y - self.previousOffset;
if (diff != 0) {
self.previousOffset = 0;
self.isFinding = NO;
if (diff > 0) {
// moved up
} else {
// moved down
}
}
}
}
}

I shared my experience of using two LEFT JOINS in a single SQL query.
I have 3 tables:
Table 1) Patient consists columns PatientID, PatientName
Table 2) Appointment consists columns AppointmentID, AppointmentDateTime, PatientID, DoctorID
Table 3) Doctor consists columns DoctorID, DoctorName
Query:
SELECT Patient.patientname, AppointmentDateTime, Doctor.doctorname
FROM Appointment
LEFT JOIN Doctor ON Appointment.doctorid = Doctor.doctorId //have doctorId column common
LEFT JOIN Patient ON Appointment.PatientId = Patient.PatientId //have patientid column common
WHERE Doctor.Doctorname LIKE 'varun%' // setting doctor name by using LIKE
AND Appointment.AppointmentDateTime BETWEEN '1/16/2001' AND '9/9/2014' //comparison b/w dates
ORDER BY AppointmentDateTime ASC; // getting data as ascending order
I wrote the solution to get date format like "mm/dd/yy" (under my name "VARUN TEJ REDDY")
Thanks for David Brown's answer. In my case of JSON.Net 3.5, the convert methods are under the JsonConvert static class:
XmlNode myXmlNode = JsonConvert.DeserializeXmlNode(myJsonString); // is node not note
// or .DeserilizeXmlNode(myJsonString, "root"); // if myJsonString does not have a root
string jsonString = JsonConvert.SerializeXmlNode(myXmlNode);
What you want to do is certainly achievable.
What you want is to wrap each 'group' in a row, not the whole form with just one row. Here:
<div class="container">
<h1>My form</h1>
<p>How to make these input fields small and retain the layout.</p>
<form role="form">
<div class="row">
<div class="form-group col-lg-1">
<label for="code">Name</label>
<input type="text" class="form-control" />
</div>
</div>
<div class="row">
<div class="form-group col-lg-1 ">
<label for="code">Email</label>
<input type="text" class="form-control input-normal" />
</div>
</div>
<div class="row">
<button type="submit" class="btn btn-default">Submit</button>
</div>
</form>
</div>
The NEW jsfiddle I made: NEW jsfiddle
Note that in the new fiddle, I've also added 'col-xs-5' so you can see it in smaller screens too - removing them makes no difference. But keep in mind in your original classes, you are only using 'col-lg-1'. That means if the screen width is smaller than the 'lg' media query size, then the default block behaviour is used. Basically by only applying 'col-lg-1', the logic you're employing is:
IF SCREEN WIDTH < 'lg' (1200px by default)
USE DEFAULT BLOCK BEHAVIOUR (width=100%)
ELSE
APPLY 'col-lg-1' (~95px)
See Bootstrap 3 grid system for more info. I hope I was clear otherwise let me know and I'd elaborate.
Well, longs can't hold anything but integers.
One option is to use a float: float('234.89')
The other option is to truncate or round. Converting from a float to a long will truncate for you: long(float('234.89'))
>>> long(float('1.1'))
1L
>>> long(float('1.9'))
1L
>>> long(round(float('1.1')))
1L
>>> long(round(float('1.9')))
2L
strcpy(str1+strlen(str1), str2);
The main difference between the two is where it is stored and how it is accessed.
$.fn.attr
stores the information directly on the element in attributes which are publicly visible upon inspection, and also which are available from the element's native API.
$.fn.data
stores the information in a ridiculously obscure place. It is located in a closed over local variable called data_user
which is an instance of a locally defined function Data. This variable is not accessible from outside of jQuery directly.
Data set with attr()
$(element).attr('data-name')
element.getAttribute('data-name')
,data-name
also accessible from $(element).data(name)
and element.dataset['name']
and element.dataset.name
Data set with .data()
.data(name)
.attr()
or anywhere elseAs some websites and other article specifies, its simple have a look to this one. https://www.sqlitetutorial.net/sqlite-import-csv/
We don't need to specify the separator for csv
file, becayse csv means comma separated.
sqlite> .separator ,
no need of this line.
sqlite> create table cities(name, population);
sqlite> .mode csv

This will work flawlessly :)

In user crontab (crontab -e
) do not put the user field.
Correct cron is:

Syntax with user field is for /etc/crontab

In bootstrap you can use .text-center
to align center. also add .row
and .col-md-*
to your code.

Funkodebat posted a great solution which I have referenced many times. Still, I find myself writing my own working model each time I need this. So, here is my working model... with some added clarity.
First of all, the height of the text is equal to the pixel font size. Now, this was something I read a while ago, and it has worked out in my calculations. I'm not sure if this works with all fonts, but it seems to work with Arial, sans-serif.
Also, to make sure that you fit all of the text in your canvas (and don't trim the tails off of your "p"'s) you need to set context.textBaseline*.
You will see in the code that we are rotating the text about its center. To do this, we need to set context.textAlign = "center" and the context.textBaseline to bottom, otherwise, we trim off parts of our text.
Why resize the canvas?
I usually have a canvas that isn't appended to the page. I use it to draw all of my rotated text, then I draw it onto another canvas which I display.
For example, you can use this canvas to draw all of the labels for a chart (one by one) and draw the hidden canvas onto the chart canvas where you need the label (context.drawImage(hiddenCanvas, 0, 0);
).
IMPORTANT NOTE: Set your font before measuring your text, and re-apply all of your styling to the context after resizing your canvas. A canvas's context is completely reset when the canvas is resized.
Hope this helps!

innerText property sets or returns the text content as plain text of the specified node, and all its descendants whereas the innerHTML property gets and sets the plain text or HTML contents in the elements. Unlike innerText, inner HTML lets you work with HTML rich text and doesn’t automatically encode and decode text.
Try
1. List all packages
android list sdk --all
2. Install packages using following command
android update sdk -u -a -t package1, package2, package3 //comma seperated packages obtained using list command
You could install $ gem install foreman
, and use foreman to start your server as defined in your Procfile
like:
web: bundle exec rails -p 10524
You can check foreman
gem docs here: https://github.com/ddollar/foreman for more info
The benefit of this approach is not only can you set/change the port in the config easily and that it doesn't require much code to be added but also you can add different steps in the Procfile
that foreman will run for you so you don't have to go though them each time you want to start you application something like:
bundle: bundle install
web: bundle exec rails -p 10524

Ignoring the specific needs of this question, and while its never a good idea to cast a string to a bool, one way would be to use the ToBoolean() method on the Convert class:
bool val = Convert.ToBoolean("true");
or an extension method to do whatever weird mapping you're doing:
public static class StringExtensions
{
public static bool ToBoolean(this string value)
{
switch (value.ToLower())
{
case "true":
return true;
case "t":
return true;
case "1":
return true;
case "0":
return false;
case "false":
return false;
case "f":
return false;
default:
throw new InvalidCastException("You can't cast that value to a bool!");
}
}
}
The browser is preventing you from cross-site scripting.
If the url is outside of your domain, then you need to do this on the server side or move it into your domain.
CAST(timestamp_expression AS DATE)
For example, The query is : SELECT CAST(SYSTIMESTAMP AS DATE) FROM dual;
publish data where stoloc = 'AB143'
|
[select prtnum where stoloc = @stoloc]
This is how the @
works.
Normally updating certifi and/or the certifi cacert.pem
file would work. I also had to update my version of python. Vs. 2.7.5 wasn't working because of how it handles SNI requests.
Once you have an up to date pem file you can make your http request using:
requests.get(url, verify='/path/to/cacert.pem')
By the way, instead of generating the x and y coordinates yourself, you can also use the curve()
function, which is intended to draw curves corresponding to a function (such as the density of a standard normal function).
see
help(curve)
and its examples.
And if you want to add som text to properly label the mean and standard deviations, you can use the text()
function (see also plotmath
, for annotations with mathematical symbols) .
see
help(text)
help(plotmath)
You can use StringEscapeUtils from Apache Commons Logging utility or escape manually using code for each character.
I think the most complete answer to this is the accepted answer found here:
How to get tkinter working with Ubuntu's default Python 2.7 install?
I figured it out after way too much time spent on this problem, so hopefully I can save someone else the hassle.
I found this old bug report deemed invalid that mentioned the exact problem I was having, I had Tkinter.py, but it couldn't find the module _tkinter: http://bugs.python.org/issue8555
I installed the tk-dev package with apt-get, and rebuilt Python using ./configure, make, and make install in the Python2.7.3 directory. And now my Python2.7 can import Tkinter, yay!
I'm a little miffed that the tk-dev package isn't mentioned at all in the Python installation documentation.... below is another helpful resource on missing modules in Python if, like me, someone should discover they are missing more than _tkinter.

The alternative would be to use ServletContext.getResource() which returns a URI. This URI may be a 'file:' URL, but there's no guarantee for that.
You don't need it to be a file:... URL. You just need it to be a URL that your JVM can read--and it will be.

To store the changed line into a variable, use below syntax:

output:OVERflow
Try this method:
look for this file
"RedirectifAuthenticated.php"
update the following as you would prefer
if (Auth::guard($guard)->check()) {
return redirect('/');
}
$guard as an arg will take in the name of the custom guard you have set eg. "admin" then it should be like this.
if (Auth::guard('admin')->check()) {
return redirect('/admin/dashboard');
}else{
return redirect('/admin/login');
}

I don't mention basics like syntax highlighting as I expect these by default.
This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.
PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?
We have a comprehensive wiki page for this question https://wiki.python.org/moin/IntegratedDevelopmentEnvironments
All of the above responses seem to obscure the simplicity of the answer or have some nuances that are not explained.
If the file is shared publicly, you can generate a direct download link by just knowing the file ID. The URL must be in the form " https://drive.google.com/uc?id=[FILEID]&export=download" This works as of 11-22-2019. This does not require the receiver to log in to google but does require the file to be shared publicly.
In your browser, navigate to drive.google.com.
Right click on the file, and click "Get a shareable link"
Edit the URL so it is in the following format, replacing "[FILEID]" with the ID of your shared file:
That's your direct download link. If you click on it in your browser the file will now be "pushed" to your browser, opening the download dialog, allowing you to save or open the file. You can also use this link in your download scripts.
So the equivalent curl command would be:
curl -L "https://drive.google.com/uc?id=AgOATNfjpovfFrft9QYa-P1IeF9e7GWcH&export=download" > phlat-1.0.tar.gz
I actually ran into an issue where I had to define winsock2.h as the first include, it seems it has other issues with includes from other packages. Hope this is helpful to someone who runs into same issue, not just windows.h but all includes.
You are getting the same random number each time, because you are setting a seed inside the loop. Even though you're using time()
, it only changes once per second, so if your loop completes in a second (which it likely will), you'll get the same seed value each time, and the same initial random number.
Move the srand()
call outside the loop (and call it only once, at the start of your app) and you should get random "random" numbers.
I know there have been a bunch of answers but the best way I have found to do this without causing a full page refresh is to create a dummy parameter on the route that I want to refresh and then when I call the route I pass in a random number to the dummy paramter.
.state("coverage.check.response", {
params: { coverageResponse: null, coverageResponseId: 0, updater: 1 },
views: {
"coverageResponse": {
templateUrl: "/Scripts/app/coverage/templates/coverageResponse.html",
controller: "coverageResponseController",
controllerAs: "vm"
}
}
})
and then the call to that route
$state.go("coverage.check.response", { coverageResponse: coverage, updater: Math.floor(Math.random() * 100000) + 1 });
Works like a charm and handles the resolves.
The plus operator converts operands to int first and then does the addition. So the result is the int. You need to cast it back to short explicitly because conversions from a "longer" type to "shorter" type a made explicit, so that you don't loose data accidentally with an implicit cast.
As to why int16 is cast to int, the answer is, because this is what is defined in C# spec. And C# is this way is because it was designed to closely match to the way how CLR works, and CLR has only 32/64 bit arithmetic and not 16 bit. Other languages on top of CLR may choose to expose this differently.
private function sendHttpRequest($host, $path, $query, $port=80){
header("POST $path HTTP/1.1\r\n" );
header("Host: $host\r\n" );
header("Content-type: application/x-www-form-urlencoded\r\n" );
header("Content-length: " . strlen($query) . "\r\n" );
header("Connection: close\r\n\r\n" );
header($query);
}
This will get you right away
Another case is http redirection. If your page redirects http requests to https, then may be your partial view tries to redirect by itself.
It causes same problem again. For this problem, you can reorganize your .net error pages or iis error pages configuration.
Just make sure you are redirecting requests to right error or not found page and make sure this error page contains non problematic partial. If your page supports only https, do not forward requests to error page without using https, if error page contains partial, this partials tries to redirect seperately from requested url, it causes problem.

Thats the way to go:

Parts of the GCC runtime (the exception handling, in particular) are dependent on the threading model being used. So, if you're using the version of the runtime that was built with POSIX threads, but decide to create threads in your own code with the Win32 APIs, you're likely to have problems at some point.
Even if you're using the Win32 threading version of the runtime you probably shouldn't be calling the Win32 APIs directly. Quoting from the MinGW FAQ:
As MinGW uses the standard Microsoft C runtime library which comes with Windows, you should be careful and use the correct function to generate a new thread. In particular, the
CreateThread
function will not setup the stack correctly for the C runtime library. You should use_beginthreadex
instead, which is (almost) completely compatible withCreateThread
.
Determining the index from the boolean as described above e.g.
df[df['column'].isin(values)].index
can be more memory intensive than determining the index using this method
pd.Index(np.where(df['column'].isin(values))[0])
applied like so
df.drop(pd.Index(np.where(df['column'].isin(values))[0]), inplace = True)
This method is useful when dealing with large dataframes and limited memory.
If you don't like remembering SQL syntax, using Mig# you can simply:
var schema = new DbSchema(ConnectionString, DbPlatform.SqlServer2014);
schema.Alter(db => db.CreateTable("Customer")
.WithPrimaryKeyColumn("Id", DbType.Int32).AsIdentity()
.WithNotNullableColumn("First_Name", DbType.String).OfSize(50)
.WithNotNullableColumn("Last_Name", DbType.String).OfSize(50)
...);
If you are not sure if it already exists, call DropIfExists
before:
db.Tables["Customers"].DropIfExists();
{% for i in yourlist %}
{% for k,v in i.items() %}
{# do what you want here #}
{% endfor %}
{% endfor %}

When you install Django on your computer all things go fine but when you install a Virtual environment it gets separated from all things. You will know it's importance when you will make a final project and deploy it to any cloud or hosting.
Just reinstall Django in the virtual environment and baam:
pip install Django
and then just run the command for testing:
python manage.py runsever
and you are all done.
fopen()
will open a resource in the same directory as the file executing the command. In other words, if you're just running the file ~/test.php, your script will create ~/myText.txt.
This can get a little confusing if you're using any URL rewriting (such as in an MVC framework) as it will likely create the new file in whatever the directory contains the root index.php file.
Also, you must have correct permissions set and may want to test before writing to the file. The following would help you debug:
$fp = fopen("myText.txt","wb");
if( $fp == false ){
//do debugging or logging here
}else{
fwrite($fp,$content);
fclose($fp);
}
Ok I did it with some trick ;) First build a UITextField
and increased it's size
like this :
CGRect frameRect = textField.frame;
frameRect.size.height = 53;
textField.frame = frameRect;
Then build a UITextView
exactly in the same area that u made my UITextField
, and deleted its background color
. Now it looks like that u have a multiple lines TextField
!
What if:
<asp:Button ID="Button1" runat="server" CssClass="test1 test3 test-test" />
To add or remove a class, instead of overwriting all classes with
BtnventCss.CssClass = "hom_but_a"
keep the HTML correct:
string classname = "TestClass";
// Add a class
BtnventCss.CssClass = String.Join(" ", Button1
.CssClass
.Split(' ')
.Except(new string[]{"",classname})
.Concat(new string[]{classname})
.ToArray()
);
// Remove a class
BtnventCss.CssClass = String.Join(" ", Button1
.CssClass
.Split(' ')
.Except(new string[]{"",classname})
.ToArray()
);
This assures
Especially when client-side development is using several classnames on one element.
In your example, use
string classname = "TestClass";
// Add a class
Button1.Attributes.Add("class", String.Join(" ", Button1
.Attributes["class"]
.Split(' ')
.Except(new string[]{"",classname})
.Concat(new string[]{classname})
.ToArray()
));
// Remove a class
Button1.Attributes.Add("class", String.Join(" ", Button1
.Attributes["class"]
.Split(' ')
.Except(new string[]{"",classname})
.ToArray()
));
You should wrap this in a method/property ;)
qrcode-generator on Github. Simplest script and works like charm.
Pros:
DC is your domain. If you want to connect to the domain example.com than your dc's are: DC=example,DC=com
You actually don't need any hostname or ip address of your domain controller (There could be plenty of them).
Just imagine that you're connecting to the domain itself. So for connecting to the domain example.com you can simply write
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
And you're done.
You can also specify a user and a password used to connect:
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com", "username", "password");
Also be sure to always write LDAP in upper case. I had some trouble and strange exceptions until I read somewhere that I should try to write it in upper case and that solved my problems.
The directoryEntry.Path
Property allows you to dive deeper into your domain. So if you want to search a user in a specific OU (Organizational Unit) you can set it there.
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
directoryEntry.Path = "LDAP://OU=Specific Users,OU=All Users,OU=Users,DC=example,DC=com";
This would match the following AD hierarchy:
Simply write the hierarchy from deepest to highest.
Now you can do plenty of things
For example search a user by account name and get the user's surname:
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
DirectorySearcher searcher = new DirectorySearcher(directoryEntry) {
PageSize = int.MaxValue,
Filter = "(&(objectCategory=person)(objectClass=user)(sAMAccountName=AnAccountName))"
};
searcher.PropertiesToLoad.Add("sn");
var result = searcher.FindOne();
if (result == null) {
return; // Or whatever you need to do in this case
}
string surname;
if (result.Properties.Contains("sn")) {
surname = result.Properties["sn"][0].ToString();
}

or
Just use Maven repository servers like Sonatype Nexus http://www.sonatype.org/nexus/ or JFrog Artifactory https://www.jfrog.com/artifactory/.
After one developer builds a project, build by next developers or Jenkins CI will not require Internet access.
Maven repository server also can have proxies configured to access Maven Central (or more needed public repositories), and they can have cynch'ed list of artifacts in remote repositories.
Some options:
tr
tr -d '\15\32' < windows.txt > unix.txt
OR
tr -d '\r' < windows.txt > unix.txt
perl
perl -p -e 's/\r$//' < windows.txt > unix.txt
sed
sed 's/^M$//' windows.txt > unix.txt
OR
sed 's/\r$//' windows.txt > unix.txt
To obtain ^M
, you have to type CTRL-V
and then CTRL-M
.
First, you have to create your own inline TS-Class, since the FormData Class is not well supported at the moment:
var data : {
name: string;
file: File;
} = {
name: "Name",
file: inputValue.files[0]
};
Then you send it to the Server with JSON.stringify(data)
let opts: RequestOptions = new RequestOptions();
opts.method = RequestMethods.Post;
opts.headers = headers;
this.http.post(url,JSON.stringify(data),opts);
You must use this code in angular to add the image path. if your images are under assets folder then.
<img src="../assets/images/logo.png" id="banner-logo" alt="Landing Page"/>
if not under the assets folder then you can use this code.
<img src="../images/logo.png" id="banner-logo" alt="Landing Page"/>

As mentioned by Zeeshan, the logrotate options size
, minsize
, maxsize
are triggers for rotation.
To better explain it. You can run logrotate as often as you like, but unless a threshold is reached such as the filesize being reached or the appropriate time passed, the logs will not be rotated.
The size options do not ensure that your rotated logs are also of the specified size. To get them to be close to the specified size you need to call the logrotate program sufficiently often. This is critical.
For log files that build up very quickly (e.g. in the hundreds of MB a day), unless you want them to be very large you will need to ensure logrotate is called often! this is critical.
Therefore to stop your disk filling up with multi-gigabyte log files you need to ensure logrotate is called often enough, otherwise the log rotation will not work as well as you want.
on Ubuntu, you can easily switch to hourly rotation by moving the script /etc/cron.daily/logrotate to /etc/cron.hourly/logrotate
Or add
*/5 * * * * /etc/cron.daily/logrotate
To your /etc/crontab file. To run it every 5 minutes.
The size
option ignores the daily, weekly, monthly time options. But minsize & maxsize take it into account.
The man page is a little confusing there. Here's my explanation.
minsize
rotates only when the file has reached an appropriate size and the set time period has passed. e.g. minsize 50MB + daily
If file reaches 50MB before daily time ticked over, it'll keep growing until the next day.
maxsize
will rotate when the log reaches a set size or the appropriate time has passed.
e.g. maxsize 50MB + daily.
If file is 50MB and we're not at the next day yet, the log will be rotated. If the file is only 20MB and we roll over to the next day then the file will be rotated.
size
will rotate when the log > size. Regardless of whether hourly/daily/weekly/monthly is specified. So if you have size 100M - it means when your log file is > 100M the log will be rotated if logrotate is run when this condition is true. Once it's rotated, the main log will be 0, and a subsequent run will do nothing.
So in the op's case. Specficially 50MB max I'd use something like the following:
/var/log/logpath/*.log {
maxsize 50M
hourly
missingok
rotate 8
compress
notifempty
nocreate
}
Which means he'd create 8hrs of logs max. And there would be 8 of them at no more than 50MB each. Since he's saying that he's getting multi gigabytes each day and assuming they build up at a fairly constant rate, and maxsize is used he'll end up with around close to the max reached for each file. So they will be likely close to 50MB each. Given the volume they build, he would need to ensure that logrotate is run often enough to meet the target size.
Since I've put hourly there, we'd need logrotate to be run a minimum of every hour. But since they build up to say 2 gigabytes per day and we want 50MB... assuming a constant rate that's 83MB per hour. So you can imagine if we run logrotate every hour, despite setting maxsize to 50 we'll end up with 83MB log's in that case. So in this instance set the running to every 30 minutes or less should be sufficient.
Ensure logrotate is run every 30 mins.

From your comments, it seems like you're looking for "best practices" for the use of the Boolean
wrapper class. But there really aren't any best practices, because it's a bad idea to use this class to begin with. The only reason to use the object wrapper is in cases where you absolutely must (such as when using Generics, i.e., storing a boolean
in a HashMap<String, Boolean>
or the like). Using the object wrapper has no upsides and a lot of downsides, most notably that it opens you up to NullPointerException
s.
Does it matter if '!' is used instead of .equals() for Boolean?
Both techniques will be susceptible to a NullPointerException
, so it doesn't matter in that regard. In the first scenario, the Boolean
will be unboxed into its respective boolean
value and compared as normal. In the second scenario, you are invoking a method from the Boolean
class, which is the following:
public boolean equals(Object obj) {
if (obj instanceof Boolean) {
return value == ((Boolean)obj).booleanValue();
}
return false;
}
Either way, the results are the same.
Would it matter if .equals(false) was used to check for the value of the Boolean checker?
Per above, no.
Secondary question: Should Boolean be dealt differently than boolean?
If you absolutely must use the Boolean
class, always check for null
before performing any comparisons. e.g.,
Map<String, Boolean> map = new HashMap<String, Boolean>();
//...stuff to populate the Map
Boolean value = map.get("someKey");
if(value != null && value) {
//do stuff
}
This will work because Java short-circuits conditional evaluations. You can also use the ternary operator.
boolean easyToUseValue = value != null ? value : false;
But seriously... just use the primitive type, unless you're forced not to.
// Following is angular 2.0 directive for window re size that adjust scroll bar for give element as per your tag

})
export class AutoResize {

$window: any;
constructor(_element: ElementRef) {
this.element = _element;
// Get instance of DOM window.
this.$window = angular.element(window);
this.onResize();
}
// Adjust height of element.
onResize() {
$(this.element.nativeElement).css('height', (this.$window.height() - 163) + 'px');
}
}

Use the following command:
git clone --depth <depth> -b <branch> <repo_url>
Where:
depth
is the amount of commits you want to include. i.e. if you just want the latest commit use git clone --depth 1
branch
is the name of the remote branch that you want to clone from. i.e. if you want the last 3 commits from master
branch use git clone --depth 3 -b master
repo_url
is the url of your repositoryShorter version:
dependencies {
implementation fileTree('lib')
}
This can easily be done by using the Linq extension method Union. For example:
var mergedList = list1.Union(list2).ToList();
This will return a List in which the two lists are merged and doubles are removed. If you don't specify a comparer in the Union extension method like in my example, it will use the default Equals and GetHashCode methods in your Person class. If you for example want to compare persons by comparing their Name property, you must override these methods to perform the comparison yourself. Check the following code sample to accomplish that. You must add this code to your Person class.
/// <summary>
/// Checks if the provided object is equal to the current Person
/// </summary>
/// <param name="obj">Object to compare to the current Person</param>
/// <returns>True if equal, false if not</returns>
public override bool Equals(object obj)
{
// Try to cast the object to compare to to be a Person
var person = obj as Person;
return Equals(person);
}
/// <summary>
/// Returns an identifier for this instance
/// </summary>
public override int GetHashCode()
{
return Name.GetHashCode();
}
/// <summary>
/// Checks if the provided Person is equal to the current Person
/// </summary>
/// <param name="personToCompareTo">Person to compare to the current person</param>
/// <returns>True if equal, false if not</returns>
public bool Equals(Person personToCompareTo)
{
// Check if person is being compared to a non person. In that case always return false.
if (personToCompareTo == null) return false;
// If the person to compare to does not have a Name assigned yet, we can't define if it's the same. Return false.
if (string.IsNullOrEmpty(personToCompareTo.Name) return false;
// Check if both person objects contain the same Name. In that case they're assumed equal.
return Name.Equals(personToCompareTo.Name);
}
If you don't want to set the default Equals method of your Person class to always use the Name to compare two objects, you can also write a comparer class which uses the IEqualityComparer interface. You can then provide this comparer as the second parameter in the Linq extension Union method. More information on how to write such a comparer method can be found on http://msdn.microsoft.com/en-us/library/system.collections.iequalitycomparer.aspx
How are you adding your Weblogic classes to the classpath in Eclipse? Are you using WTP, and a server runtime? If so, is your server runtime associated with your project?
If you right click on your project and choose build path->configure
build path and then choose the libraries tab. You should see the weblogic libraries associated here. If you do not you can click Add Library->Server Runtime
. If the library is not there, then you first need to configure it. Windows->Preferences->Server->Installed runtimes
Here is what made the error disappear for me:
Close eclipse, open up a terminal window and run:
$ mvn clean eclipse:clean eclipse:eclipse
Are you using Maven? If so,
To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.
And then clean
Edit 1:
If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.
Edit 2:
You can also try going into the folder where you have all your projects and delete the .metadata
for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.
This will create a dropdown menu from an array and automatically assign its respective value.
<?php
$names = array('tn'=>'Tunisia','us'=>'United States','fr'=>'France');
echo '<select name="countries">';
foreach($names AS $let=>$word){
echo '<option value="'.$let.'">'.$word.'</option>';
}
echo '</select>';
?>
<select name="countries">
<?php
$countries = array('tn'=> "Tunisia", "us"=>'United States',"fr"=>'France');
foreach($countries as $select=>$country_name){
echo '<option value="' . $select . '">' . $country_name . '</option>';
}
?>
</select>
<?php
$my_array = array(
'tn' => 'Tunisia',
'us' => 'United States',
'fr' => 'France'
);
echo '<select name="countries">';
echo '<option value="none">Select...</option>';
foreach ($my_array as $k => $v) {
echo '<option value="' . $k . '">' . $v . '</option>';
}
echo '</select>';
?>
OK, this question has been answered and answer accepted but someone asked me to put my answer so there you go.
First of all, it is not possible to say for sure. It is an internal implementation detail and not documented. However, based on the objects included in the other object. Now, how do we calculate the memory requirement for our cached objects?
I had previously touched this subject in this article:
Now, how do we calculate the memory requirement for our cached objects? Well, as most of you would know, Int32 and float are four bytes, double and DateTime 8 bytes, char is actually two bytes (not one byte), and so on. String is a bit more complex, 2*(n+1), where n is the length of the string. For objects, it will depend on their members: just sum up the memory requirement of all its members, remembering all object references are simply 4 byte pointers on a 32 bit box. Now, this is actually not quite true, we have not taken care of the overhead of each object in the heap. I am not sure if you need to be concerned about this, but I suppose, if you will be using lots of small objects, you would have to take the overhead into consideration. Each heap object costs as much as its primitive types, plus four bytes for object references (on a 32 bit machine, although BizTalk runs 32 bit on 64 bit machines as well), plus 4 bytes for the type object pointer, and I think 4 bytes for the sync block index. Why is this additional overhead important? Well, let’s imagine we have a class with two Int32 members; in this case, the memory requirement is 16 bytes and not 8.
Hi I have same issue tried almost everything. So, finally i resolved after 6 hour long struggle by debugging everything line by line.
classpath 'com.google.gms:google-services:3.0.0'
Google-services 3.0 Doesn't support firebase with Studio 3.0 with playServiceVersion: 11.6.0 or less.
implementation "com.google.firebase:firebase-messaging:$rootProject.ext.playServiceVersion"
implementation "com.google.firebase:firebase-core:$rootProject.ext.playServiceVersion"
implementation "com.firebase:firebase-jobdispatcher-with-gcm-dep:$rootProject.ext.jobdispatcherVersion"
Solution :
I have change google services to
classpath 'com.google.gms:google-services:3.1.1'
And it support firebase services.
Hopefully somebody save his/her time.

For me I moved the location of the logfiles and it was only when I changed the name of the file to something else it started again.
It seems if there is a logfile with the same name already existing, nothing happens.
Afterwards I rename the old file and changed the log filename in the config back again to what it was.
Rather than changing the RegKey, I was able to put a line in the header of my HTML:

<!-- Insert other header tags here -->

I encountered this error when running my Android app on my home WiFi, then trying to run it on different WiFi without closing my simulator.
Simply closing the simulator and re-launching the app worked for me!

You can quite simply add the line:
source ~/.profile
To the bottom of your shell rc file - if you are using bash then it would be your ~/.bash_profile if you are using zsh it would be your ~/.zshrc
Then open a new Terminal window and type ports -v you should see output that looks like the following:

What I did is to hide the Sidebar and then make appear the navbar with breakpoints

This worked for me:
sudo dnf install java-<version>-devel
Solution without having to change Windows HOME variable
OS: Windows 10
git version: 2.27.0.windows.1
I use portable version of Git, so all my config files are on my pen-drive(E:). This is what worked for me:
.gitconfig
and other bash files in E, so I created a folder called home where I want them all in.mkdir home
HOME="E:\git\home"
Now it no longer searches in the C:\Users<username> directory for .gitconfig but only looks in your set path above.
$ git config --global --list
fatal: unable to read config file 'E:/git/home/.gitconfig': No such file or directory
It gave an error because there isn't a .gitconfig file there yet. This is just to demonstrate that we have successfully changed the location of the .gitconfig file without changing the HOME directory in Windows.
For just two strings, you definitely do not want to use StringBuilder. There is some threshold above which the StringBuilder overhead is less than the overhead of allocating multiple strings.
So, for more that 2-3 strings, use DannySmurf's code. Otherwise, just use the + operator.
Usually when I want to pass arguments to an alias in Bash, I use a combination of an alias and a function like this, for instance:
function __t2d {
if [ "$1x" != 'x' ]; then
date -d "@$1"
fi
}
alias t2d='__t2d'
First, remove the old version:
If installed via apt-get
sudo apt-get remove docker-compose
If installed via curl
sudo rm /usr/local/bin/docker-compose
If installed via pip
pip uninstall docker-compose
Then find the newest version on the release page at GitHub or by curling the API if you have jq
installed (thanks to dragon788 and frbl for this improvement):
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
Finally, download to your favorite $PATH-accessible location and set permissions:
DESTINATION=/usr/local/bin/docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
sudo chmod 755 $DESTINATION
You might want to look at csounds, also. It has several API's, including Python. It might be able to interact with an A-D interface and gather sound samples.

When working with async functions or observables provided by 3rd party libraries, for example Cloud firestore, I've found functions the waitFor
method shown below (TypeScript, but you get the idea...) to be helpful when you need to wait on some process to complete, but you don't want to have to embed callbacks within callbacks within callbacks nor risk an infinite loop.
This method is sort of similar to a while (!condition)
sleep loop, but
yields asynchronously and performs a test on the completion condition at regular intervals till true or timeout.
export const sleep = (ms: number) => {
return new Promise(resolve => setTimeout(resolve, ms))
}
/**
* Wait until the condition tested in a function returns true, or until
* a timeout is exceeded.
* @param interval The frenequency with which the boolean function contained in condition is called.
* @param timeout The maximum time to allow for booleanFunction to return true
* @param booleanFunction: A completion function to evaluate after each interval. waitFor will return true as soon as the completion function returns true.
*/
export const waitFor = async function (interval: number, timeout: number,
booleanFunction: Function): Promise<boolean> {
let elapsed = 1;
if (booleanFunction()) return true;
while (elapsed < timeout) {
elapsed += interval;
await sleep(interval);
if (booleanFunction()) {
return true;
}
}
return false;
}
The say you have a long running process on your backend you want to complete before some other task is undertaken. For example if you have a function that totals a list of accounts, but you want to refresh the accounts from the backend before you calculate, you can do something like this:
async recalcAccountTotals() : number {
this.accountService.refresh(); //start the async process.
if (this.accounts.dirty) {
let updateResult = await waitFor(100,2000,()=> {return !(this.accounts.dirty)})
}
if(!updateResult) {
console.error("Account refresh timed out, recalc aborted");
return NaN;
}
return ... //calculate the account total.
}
You can call a reset function before appending. Something like this:
function resetNewReviewBoardForm() {
$("#Description").val('');
$("#PersonName").text('');
$("#members").empty(); //this one what worked in my case
$("#EmailNotification").val('False');
}
another easy way using re will be
import re, clr
text = 'some string... this part will be removed.'
text= re.search(r'(\A.*)\.\.\..+',url,re.DOTALL|re.IGNORECASE).group(1)
// text = some string
You could simply create a sub-routine:
#Get File Contents
sub gfc
{
open FC, @_[0];
join '', <FC>;
}
Shorthand is not preferred for scripts; it is less readable. The %{} operator is considered shorthand. Here's how it should be done in a script for readability and reusability:
PS> $hash = @{
a = 1
b = 2
c = 3
}
PS> $hash
Name Value
---- -----
c 3
b 2
a 1
Note: personal preference; syntax is easier to read
The GetEnumerator() method would be done as shown:
foreach ($h in $hash.GetEnumerator()) {
Write-Host "$($h.Name): $($h.Value)"
}
Output:
c: 3
b: 2
a: 1
The Keys method would be done as shown:
foreach ($h in $hash.Keys) {
Write-Host "${h}: $($hash.Item($h))"
}
Output:
c: 3
b: 2
a: 1
Be careful sorting your hashtable...
Sort-Object may change it to an array:
PS> $hash.GetType()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Hashtable System.Object
PS> $hash = $hash.GetEnumerator() | Sort-Object Name
PS> $hash.GetType()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Object[] System.Array
Firebase now supports multiple application ids with one google-services.json file.
This blog post describes it in detail.
You'll create one parent project in Firebase that you'll use for all of your variants. You then create separate Android applications in Firebase under that project for each application id that you have.
When you created all of your variants, you can download a google-services.json that supports all of your applications ids. When it's relevant to see the data separately (i.e. Crash Reporting) you can toggle that with a dropdown.
In case you want to count the references from your model( ie: Client has Address as reference so you wanna count how many address would exists for a client) in a foreach loop at your view such as:
@foreach (var item in Model)
{
<tr>
<td>
@Html.DisplayFor(modelItem => item.DtCadastro)
</td>
<td style="width:50%">
@Html.DisplayFor(modelItem => item.DsLembrete)
</td>
<td>
@Html.DisplayFor(modelItem => item.DtLembrete)
</td>
<td>
@{
var contador = item.LembreteEnvolvido.Where(w => w.IdLembrete == item.IdLembrete).Count();
}
<button class="btn-link associado" data-id="@item.IdLembrete" data-path="/LembreteEnvolvido/Index/@item.IdLembrete"><i class="fas fa-search"></i> @contador</button>
<button class="btn-link associar" data-id="@item.IdLembrete" data-path="/LembreteEnvolvido/Create/@item.IdLembrete"><i class="fas fa-plus"></i></button>
</td>
<td class="text-right">
<button class="btn-link delete" data-id="@item.IdLembrete" data-path="/Lembretes/Delete/@item.IdLembrete">Excluir</button>
</td>
</tr>
}
do as coded:
@{ var contador = item.LembreteEnvolvido.Where(w => w.IdLembrete == item.IdLembrete).Count();}
and use it like this:
<button class="btn-link associado" data-id="@item.IdLembrete" data-path="/LembreteEnvolvido/Index/@item.IdLembrete"><i class="fas fa-search"></i> @contador</button>
ps: don't forget to add INCLUDE to that reference at you DbContext inside, for example, your Index action controller, in case this is an IEnumerable model.
max_allowed_packet
is set in mysql config, not on php side
[mysqld]
max_allowed_packet=16M
You can see it's curent value in mysql like this:
SHOW VARIABLES LIKE 'max_allowed_packet';
You can try to change it like this, but it's unlikely this will work on shared hosting:
SET GLOBAL max_allowed_packet=16777216;
You can read about it here http://dev.mysql.com/doc/refman/5.1/en/packet-too-large.html
EDIT
The [mysqld] is necessary to make the max_allowed_packet
working since at least mysql version 5.5.
Recently setup an instance on AWS EC2 with Drupal and Solr Search Engine, which required 32M max_allowed_packet
. It you set the value under [mysqld_safe]
(which is default settings came with the mysql installation) mode in /etc/my.cnf, it did no work. I did not dig into the problem. But after I change it to [mysqld]
and restarted the mysqld, it worked.
In Python 2, I didn't have a lot luck with super(). I used the answer from jimifiki on this SO thread how to refer to a parent method in python?. Then, I added my own little twist to it, which I think is an improvement in usability (Especially if you have long class names).
Define the base class in one module:
# myA.py
class A():
def foo( self ):
print "foo"
Then import the class into another modules as parent
:
# myB.py
from myA import A as parent
class B( parent ):
def foo( self ):
parent.foo( self ) # calls 'A.foo()'
SELECT @variable1 = col1, @variable2 = col2
FROM table1
If you want the actions to be more or less atomic, I would make sure to wrap them in a transaction. That way you can be sure both happened or both didn't happen as needed.
On my Windows 7 machine I have the following environment variables:
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_07
M2_HOME=C:\apache-maven-3.0.3
On my PATH
variable, I have (among others) the following:
I tried doing what you've done with %M2%
having the nested %M2_HOME%
and it also works.
You can better understand what Looper is in the context of GUI framework. Looper is made to do 2 things.
1) Looper transforms a normal thread, which terminates when its run() method return, into something run continuously until Android app is running, which is needed in GUI framework (Technically, it still terminates when run() method return. But let me clarify what I mean in below).
2) Looper provides a queue where jobs to be done are enqueued, which is also needed in GUI framework.
As you may know, when an application is launched, the system creates a thread of execution for the application, called “main”, and Android applications normally run entirely on a single thread by default the “main thread”. But main thread is not some secret, special thread. It's just a normal thread similar to threads you create with new Thread()
code, which means it terminates when its run() method return! Think of below example.
public class HelloRunnable implements Runnable {
public void run() {
System.out.println("Hello from a thread!");
}
public static void main(String args[]) {
(new Thread(new HelloRunnable())).start();
}
}
Now, let's apply this simple principle to Android apps. What would happen if an Android app runs on normal thread? A thread called "main" or "UI" or whatever starts your application, and draws all UI. So, the first screen is displayed to users. So what now? The main thread terminates? No, it shouldn’t. It should wait until users do something, right? But how can we achieve this behavior? Well, we can try with Object.wait()
or Thread.sleep()
. For example, main thread finishes its initial job to display first screen, and sleeps. It awakes, which means interrupted, when a new job to do is fetched. So far so good, but at this moment we need a queue-like data structure to hold multiple jobs. Think about a case when a user touches screen serially, and a task takes longer time to finish. So, we need to have a data structure to hold jobs to be done in first-in-first-out manner. Also, you may imagine, implementing ever-running-and-process-job-when-arrived thread using interrupt is not easy, and leads to complex and often unmaintainable code. We'd rather create a new mechanism for such purpose, and that is what Looper is all about. The official document of Looper class says, "Threads by default do not have a message loop associated with them", and Looper is a class "used to run a message loop for a thread". Now you can understand what it means.
To make things more clear, let's check the code where main thread is transformed. It all happens in ActivityThread class. In its main() method, you can find below code, which turns a normal main thread into something what we need.
public final class ActivityThread {
...
public static void main(String[] args) {
...
Looper.prepareMainLooper();
Looper.loop();
...
}
}
and Looper.loop()
method loop infinitely and dequeue a message and process one at a time:
public static void loop() {
...
for (;;) {
Message msg = queue.next(); // might block
if (msg == null) {
// No message indicates that the message queue is quitting.
return;
}
...
msg.target.dispatchMessage(msg);
...
}
}
So, basically Looper is a class that is made to address a problem that occurs in GUI framework. But this kind of needs can also happen in other situation as well. Actually it is a pretty famous pattern for multi threads application, and you can learn more about it in "Concurrent Programming in Java" by Doug Lea(Especially, chapter 4.1.4 "Worker Threads" would be helpful). Also, you can imagine this kind of mechanism is not unique in Android framework, but all GUI framework may need somewhat similar to this. You can find almost same mechanism in Java Swing framework.

, there's another chance that Scanner
can take spaces included in input.
A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.
You can use Scanner#useDelimiter()
to change the delimiter of Scanner
to another pattern such as a line feed
or something else.
Scanner in = new Scanner(System.in);
in.useDelimiter("\n"); // use LF as the delimiter
String question;
System.out.println("Please input question:");
question = in.next();
// TODO do something with your input such as removing spaces...
if (question.equalsIgnoreCase("howdoyoulikeschool?") )
/* it seems strings do not allow for spaces */
System.out.println("CLOSED!!");
else
System.out.println("Que?");
util.print can be used also. Read: http://nodejs.org/api/util.html#util_util_print
util.print([...])# A synchronous output function. Will block the process, cast each argument to a string then output to stdout. Does not place newlines after each argument.
An example:
// get total length
var len = parseInt(response.headers['content-length'], 10);
var cur = 0;
// handle the response
response.on('data', function(chunk) {
cur += chunk.length;
util.print("Downloading " + (100.0 * cur / len).toFixed(2) + "% " + cur + " bytes\r");
});
If you could somehow locate mongod.log and the do a grep over it
grep dbpath mongod.log
The value for dbpath is the data location for mongodb!! All the best :)
In your asp.net app use this
using System.Configuration;
Response.Write(ConfigurationManager.OpenMachineConfiguration().FilePath);
THE ANSWER: The problem was all of the posts for such an issue were related to older kerberos and IIS issues where proxy credentials or AllowNTLM properties were helping. My case was different. What I have discovered after hours of picking worms from the ground was that somewhat IIS installation did not include Negotiate provider under IIS Windows authentication providers list. So I had to add it and move up. My WCF service started to authenticate as expected. Here is the screenshot how it should look if you are using Windows authentication with Anonymous auth OFF.
You need to right click on Windows authentication and choose providers menu item.
Hope this helps to save some time.
Method 1: It is showing.you did not install Api 23. So please install API 23.
Method 2:
Change the appcompat version in your build.gradle file back to 22.0.1 (or less).
From the diff man page:
-q
Report only whether the files differ, not the details of the differences.
-r
When comparing directories, recursively compare any subdirectories found.
Example command:
diff -qr dir1 dir2
Example output (depends on locale):
$ ls dir1 dir2
dir1:
same-file different only-1
dir2:
same-file different only-2
$ diff -qr dir1 dir2
Files dir1/different and dir2/different differ
Only in dir1: only-1
Only in dir2: only-2
You can also use the relatively unused:

Liam's link looks great, but also check out pandas.Timedelta
- looks like it plays nicely with NumPy's and Python's time deltas.

If you don't want to make the button a separate image, you can use the <area>
tag. This is done by using html similar to this:
<img src="imgsrc" width="imgwidth" height="imgheight" alt="alttext" usemap="#mapname">
<map name="mapname">
<area shape="rect" coords="see note 1" href="link" alt="alttext">
</map>
Note 1: The coords=" "
attribute must be formatted in this way: coords="x1,y1,x2,y2"
where:
x1=top left X coordinate
y1=top left Y coordinate
x2=bottom right X coordinate
y2=bottom right Y coordinate
Note 2: The usemap="#mapname"
attribute must include the #
.
EDIT:
I looked at your code and added in the <map>
and <area>
tags where they should be. I also commented out some parts that were either overlapping the image or seemed there for no use.

is an example link.If you have Jackson integeration with your application to serialize your bean to JSON format, then you can use Jackson anotation @JsonFormat to format your date to specified format.
In your case if you need your date into yyyy-MM-dd
format you need to specify @JsonFormat
above your field on which you want to apply this format.
For Example :
public class Subject {
private String uid;
private String number;
private String initials;
@JsonFormat(pattern="yyyy-MM-dd")
private Date dateOfBirth;
//Other Code
}
From Docs :
annotation used for configuring details of how values of properties are to be serialized.
Hope this helps.
For large text, the full text index is much faster. But you can full text index varchar(max)
as well.
GitHub is the entire site. Gists are a particular service offered on that site, namely code snippets akin to pastebin. However, everything is driven by git revision control, so gists also have complete revision histories.

Try to rebuild your project - It copies the content of App.config
to
"<YourProjectName.exe>.config" in the build library.
The reason you cannot import path is because it is new in Django 2.0 as is mentioned here: https://docs.djangoproject.com/en/2.0/ref/urls/#path.
On that page in the bottom right hand corner you can change the documentation version to the version that you have installed. If you do this you will see that there is no entry for path
on the 1.11
docs.
Actually you don't have to deal with the static metamodel if you had your annotations right.
With the following entities :
@Entity
public class Pet {
@Id
protected Long id;
protected String name;
protected String color;
@ManyToOne
protected Set<Owner> owners;
}
@Entity
public class Owner {
@Id
protected Long id;
protected String name;
}
You can use this :
CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> petMetaModel = m.entity(Pet.class);
Root<Pet> pet = cq.from(Pet.class);
Join<Pet, Owner> owner = pet.join(petMetaModel.getSet("owners", Owner.class));
A view is a virtual table, which provides access to a subset of column from one or more table. A view can derive its data from one or more table. An output of query can be stored as a view. View act like small a table but it does not physically take any space. View is good way to present data in particular users from accessing the table directly. A view in oracle is nothing but a stored sql scripts. Views itself contain no data.
HttpUtility.ParseQueryString(Request.Url.Query)
return is HttpValueCollection
(internal class). It inherits from NameValueCollection
.
var qs = HttpUtility.ParseQueryString(Request.Url.Query);
qs.Remove("foo");
string url = "~/Default.aspx";
if (qs.Count > 0)
url = url + "?" + qs.ToString();
Response.Redirect(url);
The ~
selector is in fact the General sibling combinator (renamed to Subsequent-sibling combinator in selectors Level 4):
The general sibling combinator is made of the "tilde" (U+007E, ~) character that separates two sequences of simple selectors. The elements represented by the two sequences share the same parent in the document tree and the element represented by the first sequence precedes (not necessarily immediately) the element represented by the second one.
Consider the following example:
.a ~ .b {_x000D_
background-color: powderblue;_x000D_
}
_x000D_
<ul>_x000D_
<li class="b">1st</li>_x000D_
<li class="a">2nd</li>_x000D_
<li>3rd</li>_x000D_
<li class="b">4th</li>_x000D_
<li class="b">5th</li>_x000D_
</ul>
_x000D_
.a ~ .b
matches the 4th and 5th list item because they:
.b
elements .a
.a
in HTML source order.Likewise, .check:checked ~ .content
matches all .content
elements that are siblings of .check:checked
and appear after it.
Well, if I understand you correctly. You can do something like the following.
To show it, I first create a data.frame
with your example
df <-
scan(what = character(), sep = ",", text =
"001, 34, 3, aa.com
002, 4, 4, aa.com
034, 3, 3, aa.com
001, 12, 4, bb.com
002, 1, 3, bb.com
034, 2, 2, cc.com")
df <- as.data.frame(matrix(df, 6, 4, byrow = TRUE))
colnames(df) <- c("user_id", "number_of_logins", "number_of_images", "web")
You can then run one of the following lines to add a column (at the end of the data.frame
) with the row number as the generated user id. The second lines simply adds leading zeros.
df$generated_uid <- 1:nrow(df)
df$generated_uid2 <- sprintf("%03d", 1:nrow(df))
If you absolutely want the generated user id to be the first column, you can add the column like so:
df <- cbind("generated_uid3" = sprintf("%03d", 1:nrow(df)), df)
or simply rearrage the columns.
Ondrasej is the "most right" here, IMO.
There are also gui-er ways to do it, without resorting to Xcode. I like TryC.
Mac OS X includes Developer Tools, a developing environment for making Macintosh applications. However, if someone wants to study programming using C, Xcode is too big and too complicated for beginners, to write a small sample program. TryC is very suitable for beginners.
You don't need to launch a huge Xcode application, or type unfamiliar commands in Terminal. Using TryC, you can write, compile and run a C, C++ and Ruby program just like TextEdit. It's only available to compile one source code file but it's enough for trying sample programs.
Just wanted to mention react-router v4 changed radically since this question was posted/answed.
There is no <Match>
component any more! <Switch>
is to make sure only the first match is rendered. <Redirect>
well .. redirects to another route. Use or leave out exact
to either in- or exclude a partial match.
See the docs. They are great. https://reacttraining.com/react-router/
Here's an example I hope is useable to answer your question.
<Router>
<div>
<Redirect exact from='/' to='/front'/>
<Route path="/" render={() => {
return (
<div>
<h2>Home menu</h2>
<Link to="/front">front</Link>
<Link to="/back">back</Link>
</div>
);
}} />
<Route path="/front" render={() => {
return (
<div>
<h2>front menu</h2>
<Link to="/front/help">help</Link>
<Link to="/front/about">about</Link>
</div>
);
}} />
<Route exact path="/front/help" render={() => {
return <h2>front help</h2>;
}} />
<Route exact path="/front/about" render={() => {
return <h2>front about</h2>;
}} />
<Route path="/back" render={() => {
return (
<div>
<h2>back menu</h2>
<Link to="/back/help">help</Link>
<Link to="/back/about">about</Link>
</div>
);
}} />
<Route exact path="/back/help" render={() => {
return <h2>back help</h2>;
}} />
<Route exact path="/back/about" render={() => {
return <h2>back about</h2>;
}} />
</div>
</Router>
Hope it helped, let me know. If this example is not answering your question well enough, tell me and I'll see if I can modify it.
There are two reasons you might get this message:
%FrameworkDir%\%FrameworkVersion%\aspnet_regiis -i
. Read the message carefully. On Windows8/IIS8 it may say that this is no longer supported and you may have to use Turn Windows Features On/Off dialog in Install/Uninstall a Program in Control Panel.As I did not find a proper way I wrote a script to do it and I'm sharing it here for those who need it. The script runs through all user tables and collects the columns. If the column type is any char type then it tries to convert it to the given collation.
Columns has to be index and constraint free for this to work.

In laravel you can use view render. ex. $returnHTML = view('myview')->render(); myview.blade.php contains your blade code
Regarding apply
vs map
:
pool.apply(f, args)
: f
is only executed in ONE of the workers of the pool. So ONE of the processes in the pool will run f(args)
.
pool.map(f, iterable)
: This method chops the iterable into a number of chunks which it submits to the process pool as separate tasks. So you take advantage of all the processes in the pool.
Just tried both ways and in both ways I got generated .env
file:
Composer should automatically create .env file. In the post-create-project-cmd
section of the composer.json
you can find:
"post-create-project-cmd": [
"php -r \"copy('.env.example', '.env');\"",
"php artisan key:generate"
]
Both ways use the same composer.json
file, so there shoudn't be any difference.
I suggest you to update laravel/installer
to the last version: 1.2 and try again:
composer global require "laravel/installer=~1.2"
You can always generate .env
file manually by running:
cp .env.example .env
php artisan key:generate

ObjectMapper mapper = new ObjectMapper();

No, this isn't possible. In order for you to send messages of any kind to a Facebook user, you need that user's permission to do so.
If someone logs into your site with Facebook Connect, they are explicitly agreeing to share their Facebook data with your site, and you will then be able to send that person a message through the normal channels. You would also be able to fetch their friend list. However, you can not send messages to the friends.
No problems with my terminal. The above answers helped me looking in the right directions but it didn't work for me until I added 'ignore'
:
fix_encoding = lambda s: s.decode('utf8', 'ignore')
As indicated in the comment below, this may lead to undesired results. OTOH it also may just do the trick well enough to get things working and you don't care about losing some characters.
Simplest example, I could think of:
my_json = '{ "name":"John", "age":30, "car":null }'
puts JSON.pretty_generate(JSON.parse(my_json))
Rails console example:
core dev 1555:0> my_json = '{ "name":"John", "age":30, "car":null }'
=> "{ \"name\":\"John\", \"age\":30, \"car\":null }"
core dev 1556:0> puts JSON.pretty_generate(JSON.parse(my_json))
{
"name": "John",
"age": 30,
"car": null
}
=> nil
...within page DOM element tree so each control is individually accessible by its id
on the client side (within browser page) by
Having non-unique IDs on your page will still render your page, but it certainly won't be valid. Browsers are quite forgiving when parsing invalid HTML. but don't do that just because it seems that it works.
...within page DOM between several controls of the same type (think of radio buttons) so when data gets POSTed to server only a particular value gets sent. So when you have several radio buttons on your page, only the selected one's value
gets posted back to server even though there are several related radio button controls with the same name
.
Addendum to sending data to server: When data gets sent to server (usually by means of HTTP POST request) all data gets sent as name-value pairs where name is the
name
of the input HTML control and value is itsvalue
as entered/selected by the user. This is always true for non-Ajax requests. In Ajax requests name-value pairs can be independent of HTML input controls on the page, because developers can send whatever they want to the server. Quite often values are also read from input controls, but I'm just trying to say that this is not necessarily the case.
It may sometimes be beneficial that names are shared between controls of any form input type. But when? You didn't state what your server platform may be, but if you used something like Asp.net MVC you get the benefit of automatic data validation (client and server) and also binding sent data to strong types. That means that those names have to match type property names.
Now suppose you have this scenario:
So your view's model (since it displays a list) is of type IEnumerable<SomeType>
but your server side only accepts one single item of type SomeType
.
Each item is wrapped within its own FORM
element and input elements within it have the same names so when data gets to the server (from any element) it gets correctly bound to the string type expected by the controller action.
This particular scenario can be seen on my Creative stories mini-site. You won't understand the language, but you can check out those multiple forms and shared names. Never mind that ID
s are also duplicated (which is a rule violation) but that could be solved. It just doesn't matter in this case.
Just put your data into an Object like this:
var myObject = new Object();
myObject.name = "John";
myObject.age = 12;
myObject.pets = ["cat", "dog"];
Afterwards stringify it via:
var myString = JSON.stringify(myObject);
You don't need jQuery for this. It's pure JS.

I had to overcome this problem myself, when debugging web applications. -v
is great, but a little too verbose for my tastes. This is the (bash-only) solution I came up with:
curl -v http://example.com/ 2> >(sed '/^*/d')
This works because the output from -v
is sent to stderr, not stdout. By redirecting this to a subshell, we can sed
it to remove lines that start with *
. Since the real output does not pass through the subshell, it is not affected. Using a subshell is a little heavy-handed, but it's the easiest way to redirect stderr to another command. (As I noted, I'm only using this for testing, so it works fine for me.)
When you create CSS style using Dreamweaver for web designing, Dreamweaver adds a default code such as
@charset “utf-8";
Try removing this from your stylesheet, the background image or colour should display properly
This can be due to byte alignment and padding so that the structure comes out to an even number of bytes (or words) on your platform. For example in C on Linux, the following 3 structures:
#include "stdio.h"
struct oneInt {
int x;
};
struct twoInts {
int x;
int y;
};
struct someBits {
int x:2;
int y:6;
};
int main (int argc, char** argv) {
printf("oneInt=%zu\n",sizeof(struct oneInt));
printf("twoInts=%zu\n",sizeof(struct twoInts));
printf("someBits=%zu\n",sizeof(struct someBits));
return 0;
}
Have members who's sizes (in bytes) are 4 bytes (32 bits), 8 bytes (2x 32 bits) and 1 byte (2+6 bits) respectively. The above program (on Linux using gcc) prints the sizes as 4, 8, and 4 - where the last structure is padded so that it is a single word (4 x 8 bit bytes on my 32bit platform).
oneInt=4
twoInts=8
someBits=4
In Swift 3 this works:
navigationController?.navigationBar.barTintColor = UIColor.white
navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.blue]
You can try it by adding
You can examine the url through several Request
fields:
Imagine your application is listening on the following application root:
http://www.example.com/myapplication
And a user requests the following URI:
http://www.example.com/myapplication/foo/page.html?x=y
In this case the values of the above mentioned attributes would be the following:
path /foo/page.html full_path /foo/page.html?x=y script_root /myapplication base_url http://www.example.com/myapplication/foo/page.html url http://www.example.com/myapplication/foo/page.html?x=y url_root http://www.example.com/myapplication/
You can easily extract the host part with the appropriate splits.
The code below does just that. The below is a working example to log into a game. I made a similar file to log in into Yahoo and a kurzweilai.net forum.
Just copy the login form from any webpage's source code. Add value= "your user name" and value = "your password". Normally the -input- elements in the source code do not have the value attribute, and sometime, you will see something like that: value=""
Save the file as a html on a local machine double click it, or make a bat/cmd file to launch and close them as required.

Note that -script- is just -script-. I found there is no need to specify that is is JavaScript. It works anyway. I also found out that a bare-bones version that contains just two input filds: userName and password also work. But I left a hidded input field etc. just in case. Yahoo mail has a lot of hidden fields. Some are to do with password encryption, and it counts login attempts.
Security warnings and other staff, like Mark of the Web to make it work smoothly in IE are explained here:
IF NOT EXISTS(SELECT * FROM Clock
WHERE clockDate = '08/10/2012') AND userName = 'test')
Has an extra parenthesis. I think it's fine if you remove it:
IF NOT EXISTS(SELECT * FROM Clock WHERE
clockDate = '08/10/2012' AND userName = 'test')
Also, GETDATE() will put the current date in the column, though if you don't want the time you'll have to play a little. I think CONVERT(varchar(8), GETDATE(), 112) would give you just the date (not time) portion.
IF NOT EXISTS(SELECT * FROM Clock WHERE
clockDate = CONVERT(varchar(8), GETDATE(), 112)
AND userName = 'test')
should probably do it.
PS: use a merge statement :)
I just found an easy solution for myself. Had an margin-top of 15px
HTML
<h2 id="Anchor">Anchor</h2>
CSS
h2{margin-top:-60px; padding-top:75px;}
This code will print a pyramid of dollars.
public static void main(String[] args) {
for(int i=0;i<5;i++) {
for(int j=0;j<5-i;j++) {
System.out.print(" ");
}
for(int k=0;k<=i;k++) {
System.out.print("$ ");
}
System.out.println();
}
}
OUPUT :
$
$ $
$ $ $
$ $ $ $
$ $ $ $ $
$ source_file_filename_no_ext=${source_file%.*}
$ echo ${source_file_filename_no_ext##*/}
case the column isn't string, use astype to convert:
df['col'] = df['col'].astype(str).str[:9]
For multiple datetime columns with no header, and a lot of columns, say my datetime fields are in columns 36 and 38, and I want them read in as character fields:
data<-read.csv("test.csv", head=FALSE, colClasses=c("V36"="character","V38"="character"))
Another way to remove all transitions is with the unset
keyword:
a.tags {
transition: unset;
}
In the case of transition
, unset
is equivalent to initial
, since transition
is not an inherited property:
a.tags {
transition: initial;
}
A reader who knows about unset
and initial
can tell that these solutions are correct immediately, without having to think about the specific syntax of transition
.
You can use the find function:
if($('#popup').find('p.filled-text').length !== 0)
// Do Stuff
You can look at sorting the string -- treat it as a char array -- and then do a modified binary search which counts occurrences? But I agree with @tofutim that traversing it is the most efficient -- O(N) versus O(N * logN) + O(logN)
Another modelling tool for Java is (my) website GitUML. Generate UML diagrams from Java or Python code stored in GitHub repositories.
One key idea with GitUML is to address one of the problems with "documentation": that diagrams are always out of date. With GitUML, diagrams automatically update when you push code using git.
Browse through community UML diagrams, there are some Java design patterns there. Surf through popular GitHub repositories and visualise the architectures and patterns in them.
Create diagrams using point and click. There is no drag drop editor, just click on the classes in the repository tree that you want to visualise:
The underlying technology is PlantUML based, which means you can refine your diagrams with additional PlantUML markup.
Your friend here is org.springframework.web.context.request.RequestContextHolder
// example usage
public static HttpSession session() {
ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
return attr.getRequest().getSession(true); // true == allow create
}
This will be populated by the standard spring mvc dispatch servlet, but if you are using a different web framework you have add org.springframework.web.filter.RequestContextFilter
as a filter in your web.xml
to manage the holder.
EDIT: just as a side issue what are you actually trying to do, I'm not sure you should need access to the HttpSession
in the retieveUser
method of a UserDetailsService
. Spring security will put the UserDetails object in the session for you any how. It can be retrieved by accessing the SecurityContextHolder
:
public static UserDetails currentUserDetails(){
SecurityContext securityContext = SecurityContextHolder.getContext();
Authentication authentication = securityContext.getAuthentication();
if (authentication != null) {
Object principal = authentication.getPrincipal();
return principal instanceof UserDetails ? (UserDetails) principal : null;
}
return null;
}
Python 3:
import urllib.request
wp = urllib.request.urlopen("http://google.com")
pw = wp.read()
print(pw)
Python 2:
import urllib
import sys
wp = urllib.urlopen("http://google.com")
for line in wp:
sys.stdout.write(line)
While I have tested both the Codes in respective versions.
If the answers must be constrained to Google Sheets, this answer works but it has limitations and is clumsy enough UX that it may be hard to get others to adopt. In trying to solve this problem I've found that, for many applications, Airtable solves this by allowing for multi-select columns and the UX is worlds better.
Python 3 version of @DiGMi's answer:
from urllib import request
f = open('00000001.jpg', 'wb')
f.write(request.urlopen("http://www.gunnerkrigg.com/comics/00000001.jpg").read())
f.close()
In my case,I think the potential cause is Variables View
did't initial properly.
Alternative is enter another breakpoint before right code need to change variables.After entering the second breakpoint(above menthioned) added,eclipse will refresh the view and all things should be normal again.
if anyone else has problem with the above mentioned solutions, I ended up just going for the event:
$("#jquery_audioPlayer").jPlayer({
ready:function () {
$(this).jPlayer("setMedia", {
mp3:"media/song.mp3"
})
...
pause: function () {
$('#yoursoundcontrol').click(function () {
$("#jquery_audioPlayer").jPlayer('play');
})
},
play: function () {
$('#yoursoundcontrol').click(function () {
$("#jquery_audioPlayer").jPlayer('pause');
})}
});
works for me.
Solutions until now only deal with lists, and most are copying the list. In my experience a lot of times that isn't possible.
Also, they don't deal with the fact that you can have repeated elements in the list.
The title of your question says "Previous and next values inside a loop", but if you run most answers here inside a loop, you'll end up iterating over the entire list again on each element to find it.
So I've just created a function that. using the itertools
module, splits and slices the iterable, and generates tuples with the previous and next elements together. Not exactly what your code does, but it is worth taking a look, because it can probably solve your problem.
from itertools import tee, islice, chain, izip
def previous_and_next(some_iterable):
prevs, items, nexts = tee(some_iterable, 3)
prevs = chain([None], prevs)
nexts = chain(islice(nexts, 1, None), [None])
return izip(prevs, items, nexts)
Then use it in a loop, and you'll have previous and next items in it:
mylist = ['banana', 'orange', 'apple', 'kiwi', 'tomato']
for previous, item, nxt in previous_and_next(mylist):
print "Item is now", item, "next is", nxt, "previous is", previous
The results:
Item is now banana next is orange previous is None
Item is now orange next is apple previous is banana
Item is now apple next is kiwi previous is orange
Item is now kiwi next is tomato previous is apple
Item is now tomato next is None previous is kiwi
It'll work with any size list (because it doesn't copy the list), and with any iterable (files, sets, etc). This way you can just iterate over the sequence, and have the previous and next items available inside the loop. No need to search again for the item in the sequence.
A short explanation of the code:
tee
is used to efficiently create 3 independent iterators over the input sequencechain
links two sequences into one; it's used here to append a single-element sequence [None]
to prevs
islice
is used to make a sequence of all elements except the first, then chain
is used to append a None
to its endsome_iterable
that look like:
prevs
: None, A, B, C, D, E
items
: A, B, C, D, E
nexts
: B, C, D, E, None
izip
is used to change 3 sequences into one sequence of triplets.Note that izip
stops when any input sequence gets exhausted, so the last element of prevs
will be ignored, which is correct - there's no such element that the last element would be its prev
. We could try to strip off the last elements from prevs
but izip
's behaviour makes that redundant
Also note that tee
, izip
, islice
and chain
come from the itertools
module; they operate on their input sequences on-the-fly (lazily), which makes them efficient and doesn't introduce the need of having the whole sequence in memory at once at any time.
In python 3
, it will show an error while importing izip
,you can use zip
instead of izip
. No need to import zip
, it is predefined in python 3

You can do more than just fall through in C#, but you must utilize the "dreaded" goto statement. For example:
switch (whatever)
{
case 2:
Result.Write( "Subscribe" );
break;
case 1:
Result.Write( "Un" );
goto case 2;
}
HC-way :)

If you are on Linux, you just need to fill the OpenCV_DIR variable with the path of opencv (containing the OpenCVConfig.cmake file)
export OpenCV_DIR=<path_of_opencv>
You can use a Junit Rule to create this temporary folder for your test:
@Rule public TemporaryFolder temporaryFolder = new TemporaryFolder();
File file = temporaryFolder.newFile(".src/test/resources/abc.xml");
For using "overflow: scroll" you must set "display:block" on thead and tbody. And that messes up column widths between them. But then you can clone the thead row with Javascript and paste it in the tbody as a hidden row to keep the exact col widths.
$('.myTable thead > tr').clone().appendTo('.myTable tbody').addClass('hidden-to-set-col-widths');
http://jsfiddle.net/Julesezaar/mup0c5hk/
<table class="myTable">
<thead>
<tr>
<td>Problem</td>
<td>Solution</td>
<td>blah</td>
<td>derp</td>
</tr>
</thead>
<tbody></tbody>
</table>
<p>
Some text to here
</p>
The css:
table {
background-color: #aaa;
width: 100%;
}
thead,
tbody {
display: block; // Necessary to use overflow: scroll
}
tbody {
background-color: #ddd;
height: 150px;
overflow-y: scroll;
}
tbody tr.hidden-to-set-col-widths,
tbody tr.hidden-to-set-col-widths td {
visibility: hidden;
height: 0;
line-height: 0;
padding-top: 0;
padding-bottom: 0;
}
td {
padding: 3px 10px;
}
You could use id in (select id from ...) or id in (select id from ...)
e.g. instead of non-working
from Person p where p.name="Joe"
union
from Person p join p.children c where c.name="Joe"
you could do
from Person p
where p.id in (select p1.id from Person p1 where p1.name="Joe")
or p.id in (select p2.id from Person p2 join p2.children c where c.name="Joe");
At least using MySQL, you will run into performance problems with it later, though. It's sometimes easier to do a poor man's join on two queries instead:
// use set for uniqueness
Set<Person> people = new HashSet<Person>((List<Person>) query1.list());
people.addAll((List<Person>) query2.list());
return new ArrayList<Person>(people);
It's often better to do two simple queries than one complex one.
EDIT:
to give an example, here is the EXPLAIN output of the resulting MySQL query from the subselect solution:
mysql> explain
select p.* from PERSON p
where p.id in (select p1.id from PERSON p1 where p1.name = "Joe")
or p.id in (select p2.id from PERSON p2
join CHILDREN c on p2.id = c.parent where c.name="Joe") \G

The to_char()
function is there to format numbers:
select to_char(column_1, 'fm000') as column_2
from some_table;
The fm
prefix ("fill mode") avoids leading spaces in the resulting varchar. The 000
simply defines the number of digits you want to have.
psql (9.3.5) Type "help" for help. postgres=> with sample_numbers (nr) as ( postgres(> values (1),(11),(100) postgres(> ) postgres-> select to_char(nr, 'fm000') postgres-> from sample_numbers; to_char --------- 001 011 100 (3 rows) postgres=>
For more details on the format picture, please see the manual:
http://www.postgresql.org/docs/current/static/functions-formatting.html
I think you can safely say a for loop is faster.
I do admit that a regexp looks cleaner in terms of code. If it's a real bottleneck then use a for loop, otherwise stick with the regular expression for reasons of "elegance"
If you want to go for simplicity then just use
function isVowel(c) {
return ['a', 'e', 'i', 'o', 'u'].indexOf(c.toLowerCase()) !== -1
}
Think of it as a kind of turnstile like you might find at a football ground. There are parallel steams of people wanting to get in but at the turnstile they are 'synchronised'. Only one person at a time can get through. All those wanting to get through will do, but they may have to wait until they can go through.
This worked for me

I think that the solution of @Azimuts (https://stackoverflow.com/a/33375677/6503697) is for HTTP only connection. For FTPS connection you can use Bouncy Castle with org.apache.commons.net.ftp.FTPSClient without the need for rewrite FTPS protocol.
I have a program running on JRE 1.6.0_04 and I can not update the JRE.
The program has to connect to an FTPS server that work only with TLS 1.2 (IIS server).
I struggled for days and finally I have understood that there are few versions of bouncy castle library right in my use case: bctls-jdk15on-1.60.jar and bcprov-jdk15on-1.60.jar are ok, but 1.64 versions are not.
The version of apache commons-net is 3.1 .
Following is a small snippet of code that should work:
import java.io.ByteArrayOutputStream;
import java.security.SecureRandom;
import java.security.Security;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

}
public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
}
} };
@Test public void test() throws Exception {

You probably finally realized this between posting this question and today, but the very nature of selectors makes it impossible to navigate through hierarchically unrelated HTML elements.
Or, to put it simply, since you said in your comment that
there are no uniform parent containers
... it's just not possible with selectors alone, without modifying the markup in some way as shown by the other answers.
You have to use the jQuery .eq()
solution.
public static int minIndex (ArrayList<Float> list) {
return list.indexOf (Collections.min(list));
}
System.out.println("Min = " + list.get(minIndex(list));
Just use matrix
:
matrix(vec,nrow = 7,ncol = 7)
One advantage of using matrix
rather than simply altering the dimension attribute as Gavin points out, is that you can specify whether the matrix is filled by row or column using the byrow
argument in matrix
.
chmod 400 /etc/ssh/*
works for me.
Call control.invalidate and the paint event will be raised.
You could use a closure. Just modify your code like this:
google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){
return function() {
infowindow.setContent(content);
infowindow.open(map,marker);
};
})(marker,content,infowindow));

A simple way to call it from anywhere is just use "null" and "RoutedEventArgs.Empty", like this:

After a long time looking for a way to get git log
output the date in the format YYYY-MM-DD
in a way that would work in less
, I came up with the following format:
%ad%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08
along with the switch --date=iso
.
This will print the date in ISO format (a long one), and then print 14 times the backspace character (0x08), which, in my terminal, effectively removes everything after the YYYY-MM-DD part. For example:
git log --date=iso --pretty=format:'%ad%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%aN %s'
This gives something like:
2013-05-24 bruno This is the message of the latest commit.
2013-05-22 bruno This is an older commit.
...
What I did was create an alias named l
with some tweaks on the format above. It shows the commit graph to the left, then the commit's hash, followed by the date, the shortnames, the refnames and the subject. The alias is as follows (in ~/.gitconfig):
[alias]
l = log --date-order --date=iso --graph --full-history --all --pretty=format:'%x08%x09%C(red)%h %C(cyan)%ad%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08 %C(bold blue)%aN%C(reset)%C(bold yellow)%d %C(reset)%s'
For Some People, Showing status bar by clearing FLAG_FULLSCREEN may not work,
Here is the solution that worked for me, (Documentation) (Flag Reference)
Hide Status Bar

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
View decorView = getWindow().getDecorView();
// Hide Status Bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
}
Show Status Bar
if (Build.VERSION.SDK_INT < 16) {
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
View decorView = getWindow().getDecorView();
// Show Status Bar.
int uiOptions = View.SYSTEM_UI_FLAG_VISIBLE;
decorView.setSystemUiVisibility(uiOptions);
}
