Unless you're part of the 0.1% of applications where using open
is an actual performance benefit, there really is no good reason not to use fopen
. As far as fdopen
is concerned, if you aren't playing with file descriptors, you don't need that call.
Stick with fopen
and its family of methods (fwrite
, fread
, fprintf
, et al) and you'll be very satisfied. Just as importantly, other programmers will be satisfied with your code.
What you really want is logging
module from standard library. Create a logger and attach two handlers, one would be writing to a file and the other to stdout or stderr.
See Logging to multiple destinations for details
You can create an unbuffered file and assign this file to sys.stdout.
import sys
myFile= open( "a.log", "w", 0 )
sys.stdout= myFile
You can't magically change the system-supplied stdout; since it's supplied to your python program by the OS.
You should read it recursively, some time ago I had the same question and solve with this code:
public void proccessMenuNodeList(NodeList nl, JMenuBar menubar) {
for (int i = 0; i < nl.getLength(); i++) {
proccessMenuNode(nl.item(i), menubar);
}
}
public void proccessMenuNode(Node n, Container parent) {
if(!n.getNodeName().equals("menu"))
return;
Element element = (Element) n;
String type = element.getAttribute("type");
String name = element.getAttribute("name");
if (type.equals("menu")) {
NodeList nl = element.getChildNodes();
JMenu menu = new JMenu(name);
for (int i = 0; i < nl.getLength(); i++)
proccessMenuNode(nl.item(i), menu);
parent.add(menu);
} else if (type.equals("item")) {
JMenuItem item = new JMenuItem(name);
parent.add(item);
}
}
Probably you can adapt it for your case.
May I remind everybody that the question was:
I'd like to use a single image as both a regular favicon and iPhone/iPad friendly favicon? Is this possible? Would an iPad-friendly 72x72 PNG scale if linked to as a regular browser favicon? Or do I have to use a separate 16x16 or 32x32 image?
The answer is: YES, that is possible! YES, it will be scaled. NO, you do not need a 'regular browser favicon'. Please look at this answer: https://stackoverflow.com/a/48646940/2397550
The pop
method of dicts (like self.data
, i.e. {'a':'aaa','b':'bbb','c':'ccc'}
, here) takes two arguments -- see the docs
The second argument, default
, is what pop
returns if the first argument, key
, is absent.
(If you call pop
with just one argument, key
, it raises an exception if that key's absent).
In your example, print b.pop('a',{'b':'bbb'})
, this is irrelevant because 'a'
is a key in b.data
. But if you repeat that line...:
b=a()
print b.pop('a',{'b':'bbb'})
print b.pop('a',{'b':'bbb'})
print b.data
you'll see it makes a difference: the first pop
removes the 'a'
key, so in the second pop
the default
argument is actually returned (since 'a'
is now absent from b.data
).
I would recommend having a look at the plyr
package.
It might not be as fast as data.table or other packages, but it is quite instructive, especially when starting with R and having to do some data manipulation.
> DF <- data.frame(A = c("1", "1", "2", "3", "3"), B = c(2, 3, 3, 5, 6))
> library(plyr)
> DF.sum <- ddply(DF, c("A"), summarize, B = sum(B))
> DF.sum
A B

Below is a very simple Java solution which supports the push operation efficient.
Algorithm -
Declare two Queues q1 and q2.
Push operation - Enqueue element to queue q1.
Pop operation - Ensure that queue q2 is not empty. If it is empty, then dequeue all the elements from q1 except the last element and enqueue it to q2 one by one. Dequeue the last element from q1 and store it as the popped element. Swap the queues q1 and q2. Return the stored popped element.
Peek operation - Ensure that queue q2 is not empty. If it is empty, then dequeue all the elements from q1 except the last element and enqueue it to q2 one by one. Dequeue the last element from q1 and store it as the peeked element. Enqueue it back to queue q2 and swap the queues q1 and q2. Return the stored peeked element.
Below is the code for above algorithm -
class MyStack {
java.util.Queue<Integer> q1;
java.util.Queue<Integer> q2;
int SIZE = 0;
/** Initialize your data structure here. */
public MyStack() {
q1 = new LinkedList<Integer>();
q2 = new LinkedList<Integer>();
}
/** Push element x onto stack. */
public void push(int x) {
q1.add(x);
SIZE ++;
}
/** Removes the element on top of the stack and returns that element. */
public int pop() {
ensureQ2IsNotEmpty();
int poppedEle = q1.remove();
SIZE--;
swapQueues();
return poppedEle;
}
/** Get the top element. */
public int top() {
ensureQ2IsNotEmpty();
int peekedEle = q1.remove();
q2.add(peekedEle);
swapQueues();
return peekedEle;
}
/** Returns whether the stack is empty. */
public boolean empty() {
return q1.isEmpty() && q2.isEmpty();
}
/** move all elements from q1 to q2 except last element */
public void ensureQ2IsNotEmpty() {
for(int i=0; i<SIZE-1; i++) {
q2.add(q1.remove());
}
}
/** Swap queues q1 and q2 */
public void swapQueues() {
Queue<Integer> temp = q1;
q1 = q2;
q2 = temp;
}
}
In the year 2010 I would have joined the author of this questions and would have strongly voted for JOIN
, but with much more experience (especially in MySQL) I can state: Yes subqueries can be better. I've read multiple answers here; some stated subqueries are faster, but it lacked a good explanation. I hope I can provide one with this (very) late answer:
First of all, let me say the most important: There are different forms of sub-queries
And the second important statement: Size matters
If you use sub-queries, you should be aware of how the DB-Server executes the sub-query. Especially if the sub-query is evaluated once or for every row! On the other side, a modern DB-Server is able to optimize a lot. In some cases a subquery helps optimizing a query, but a newer version of the DB-Server might make the optimization obsolete.
SELECT moo, (SELECT roger FROM wilco WHERE moo = me) AS bar FROM foo
Be aware that a sub-query is executed for every resulting row from foo
.
Avoid this if possible; it may drastically slow down your query on huge datasets. However, if the sub-query has no reference to foo
it can be optimized by the DB-server as static content and could be evaluated only once.
SELECT moo FROM foo WHERE bar = (SELECT roger FROM wilco WHERE moo = me)
If you are lucky, the DB optimizes this internally into a JOIN
. If not, your query will become very, very slow on huge datasets because it will execute the sub-query for every row in foo
, not just the results like in the select-type.
SELECT moo, bar
FROM foo
LEFT JOIN (
SELECT MIN(bar), me FROM wilco GROUP BY me
) ON moo = me
This is interesting. We combine JOIN
with a sub-query. And here we get the real strength of sub-queries. Imagine a dataset with millions of rows in wilco
but only a few distinct me
. Instead of joining against a huge table, we have now a smaller temporary table to join against. This can result in much faster queries depending on database size. You can have the same effect with CREATE TEMPORARY TABLE ...
and INSERT INTO ... SELECT ...
, which might provide better readability on very complex queries (but can lock datasets in a repeatable read isolation level).
SELECT moo, bar
FROM (
SELECT moo, CONCAT(roger, wilco) AS bar
FROM foo
GROUP BY moo
HAVING bar LIKE 'SpaceQ%'
) AS temp_foo
ORDER BY bar
You can nest sub-queries in multiple levels. This can help on huge datasets if you have to group or sort the results. Usually the DB-Server creates a temporary table for this, but sometimes you do not need sorting on the whole table, only on the resultset. This might provide much better performance depending on the size of the table.
Sub-queries are no replacement for a JOIN
and you should not use them like this (although possible). In my humble opinion, the correct use of a sub-query is the use as a quick replacement of CREATE TEMPORARY TABLE ...
. A good sub-query reduces a dataset in a way you cannot accomplish in an ON
statement of a JOIN
. If a sub-query has one of the keywords GROUP BY
or DISTINCT
and is preferably not situated in the select fields or the where statement, then it might improve performance a lot.
In Android , we have the class SmsManager which manages SMS operations such as sending data, text, and pdu SMS messages. Get this object by calling the static method SmsManager.getDefault().
Check the following link to get the sample code for sending SMS:
You should find the 'expect' command will do what you need it to do. Its widely available. See here for an example : http://www.thegeekstuff.com/2010/10/expect-examples/
(very rough example)
#!/usr/bin/expect
set pass "mysecret"
spawn /usr/bin/passwd
expect "password: "
send "$pass"
expect "password: "
send "$pass"
use built in php function is_numeric
to check if the value is numeric.
Given there is only one (or with this solution potentially not even one) submit button, here is jQuery based solution that will work for multiple forms on the same page...
<script type="text/javascript">
$(document).ready(function () {
var makeAllFormSubmitOnEnter = function () {
$('form input, form select').live('keypress', function (e) {
if (e.which && e.which == 13) {
$(this).parents('form').submit();
return false;
} else {
return true;
}
});
};
makeAllFormSubmitOnEnter();
});
</script>
You can create a master page base without included js and jquery files. Put a content place holder in master page base in head section, then create a nested master page that inherits from this master page base. Now put your includes in a asp:content in nested master page, finally create a content page from this nested master page
Example:
//in master page base
<%@ master language="C#" autoeventwireup="true" inherits="MasterPage" codebehind="MasterPage.master.cs" %>
<html>
<head id="Head1" runat="server">
<asp:ContentPlaceHolder runat="server" ID="cphChildHead">
<!-- Nested Master Page include Codes will sit Here -->
</asp:ContentPlaceHolder>
</head>
<body>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
<!-- some code here -->
</body>
</html>
//in nested master page :
<%@ master language="C#" masterpagefile="~/MasterPage.master" autoeventwireup="true"
codebehind="MasterPageLib.master.cs" inherits="sampleNameSpace" %>
<asp:Content ID="headcontent" ContentPlaceHolderID="cphChildHead" runat="server">
<!-- includes will set here a nested master page -->
<link href="../CSS/pwt-datepicker.css" rel="stylesheet" type="text/css" />
<script src="../js/jquery-1.9.0.min.js" type="text/javascript"></script>
<!-- other includes ;) -->
</asp:Content>
<asp:Content ID="bodyContent" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<asp:ContentPlaceHolder ID="cphChildBody" runat="server" EnableViewState="true">
<!-- Content page code will sit Here -->
</asp:ContentPlaceHolder>
</asp:Content>
You need to tell it that you are using SSL:
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
In case you miss anything, here is working code:
String d_email = "[email protected]",
d_uname = "Name",
d_password = "urpassword",
d_host = "smtp.gmail.com",
d_port = "465",
m_to = "[email protected]",
m_subject = "Indoors Readable File: " + params[0].getName(),
m_text = "This message is from Indoor Positioning App. Required file(s) are attached.";
Properties props = new Properties();
props.put("mail.smtp.user", d_email);
props.put("mail.smtp.host", d_host);
props.put("mail.smtp.port", d_port);
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
SMTPAuthenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(props, auth);
session.setDebug(true);
MimeMessage msg = new MimeMessage(session);
try {
msg.setSubject(m_subject);
msg.setFrom(new InternetAddress(d_email));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
Transport transport = session.getTransport("smtps");
transport.connect(d_host, Integer.valueOf(d_port), d_uname, d_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
} catch (AddressException e) {
e.printStackTrace();
return false;
} catch (MessagingException e) {
e.printStackTrace();
return false;
}
Yes, this is new in PHP 5.3. It returns either the value of the test expression if it is evaluated as TRUE, or the alternative value if it is evaluated as FALSE.
There is also zzos. (Full disclosure: I wrote it). It only decompiles the actual resources, not the dex part (baksmali, which I did not write, does an excellent job of handling that part).
Zzos is much less known than apktool, but there are some APKs that are better handled by it (and vice versa - more on that later). Mostly, APKs containing custom resource types (not modifiers) were not handled by apktool the last time I checked, and are handled by zzos. There are also some cases with escaping that zzos handles better.
On the negative side of things, zzos (current version) requires a few support tools to install. It is written in perl (as opposed to APKTool, which is written in Java), and uses aapt for the actual decompilation. It also does not decompile attrib resources yet (which APKTool does).
The meaning of the name is "aapt", Android's resource compiler, shifted down one letter.
try this code ['12','34','35','231']*","
will give you result "12,34,35,231"
I hope this is the result you, let me know
int i=1;
while (true) {
WebElementdisplay=driver.findElement(By.id("__bar"+i+"-btnGo"));
System.out.println(display);
if (display.isDisplayed()==true)
{
System.out.println("inside if statement"+i);
driver.findElement(By.id("__bar"+i+"-btnGo")).click();
break;
}
else
{
System.out.println("inside else statement"+ i);
i=i+1;
}
}
Try This
var sessionValue = '<%=Session["usedData"]%>'
Without the question if it is proper or not, you can add PCH file manually:
Add new PCH file to the project: New file > Other > PCH file.
At the Target's Build Settings option, set the value of Prefix Header to your PCH file name, with the project name as prefix (i.e. for project named TestProject
and PCH file named MyPrefixHeaderFile
, add the value TestProject/MyPrefixHeaderFile.pch
to the plist).
TIP: You can use things like $(SRCROOT)
or $(PROJECT_DIR)
to get to the path of where you put the .pch
in the project.
At the Target's Build Settings option, set the value of Precompile Prefix Header to YES
.
I could use the GetBody
from Request package.
Look this comment in source code from request.go in net/http:
GetBody defines an optional func to return a new copy of Body. It is used for client requests when a redirect requires reading the body more than once. Use of GetBody still requires setting Body. For server requests it is unused."
GetBody func() (io.ReadCloser, error)
This way you can get the body request without make it empty.
Sample:
getBody := request.GetBody
copyBody, err := getBody()
if err != nil {
// Do something return err
}
http.DefaultClient.Do(request)
I think this works, too:
int power = 1;
while(power < x)
power*=2;
And the answer is power
.
Type in:
Arrays.asList(TYPES).indexOf("Sedan");
run npm i moment react-moment --save
you can use this in your component,
import Moment from 'react-moment';
const date = new Date();
<Moment format='MMMM Do YYYY, h:mm:ss a'>{date}</Moment>
Also, if you're using Rails 3 or newer you don't have to use the up
and down
methods. You can just use change
:
class ChangeFormatInMyTable < ActiveRecord::Migration
def change
change_column :my_table, :my_column, :my_new_type
end
end
The original question was about general use cases not only about memory. So it should be mentioned here that you also get better performance when instantiating large amounts of objects - interesting e.g. when parsing large documents into objects or from a database.
Here is a comparison of creating object trees with a million entries, using slots and without slots. As a reference also the performance when using plain dicts for the trees (Py2.7.10 on OSX):

Test classes (ident, appart from slots):

def __init__(self, typ, id, parent=None):
self._typ = typ
self.id = id
self.childs = []

self.parent = parent
parent.childs.append(self)
class ElementNoSlots(object): (same, w/o slots)
testcode, verbose mode:

for i in (1, 2, 3, 4):
print '*' * 10, 'RUN', i, '*' * 10
# tree with slot and no slot:
for cls in Element, ElementNoSlots:

for i in xrange(na):
ela = cls(typ='a', id=i, parent=root)
for j in xrange(nb):
elb = cls(typ='b', id=(i, j), parent=ela)
for k in xrange(nc):
elc = cls(typ='c', id=(i, j, k), parent=elb)
to = time.time() - t1
print to, cls
del root
# ref: tree with dicts only:

droot['childs'].append(ela)
for j in xrange(nb):

ela['childs'].append(elb)
for k in xrange(nc):
elc = {'typ': 'c', id: (i, j, k), 'childs': []}
elb['childs'].append(elc)
td = time.time() - t1
print td, 'dict'
del droot
It's not as easy as it seems to implement a control like that. Explorer works with shell items, not filesystem items (ex: the control panel, the printers folder, and so on). If you need to implement it i suggest to have a look at the Windows shell functions at http://msdn.microsoft.com/en-us/library/bb776426(VS.85).aspx.
Every library I can think of returns a stream. You could use IOUtils.toString()
from Apache Commons IO to read an InputStream
into a String
in one method call. E.g.:
URL url = new URL("http://www.example.com/");
URLConnection con = url.openConnection();
InputStream in = con.getInputStream();
String encoding = con.getContentEncoding();
encoding = encoding == null ? "UTF-8" : encoding;
String body = IOUtils.toString(in, encoding);
System.out.println(body);
Update: I changed the example above to use the content encoding from the response if available. Otherwise it'll default to UTF-8 as a best guess, instead of using the local system default.
It usually happens when the certificate does not match with the host name.
The solution would be to contact the host and ask it to fix its certificate.
Otherwise you can turn off cURL's verification of the certificate, use the -k
(or --insecure
) option.
Please note that as the option said, it is insecure. You shouldn't use this option because it allows man-in-the-middle attacks and defeats the purpose of HTTPS.

before you write set(XXXXX)
you have used "set" as a variable

In my case -- using React with Gatsby -- the issue was solved with double-checking all of my paths. I was using React/Gatsby with Sass and the Gatsby source files were looking for the fonts in a different place than the compiled files. Once I duplicated the files into each path this problem was gone.
Windows
Chrome
I used Ctrl + F5
keyboard combination. By doing so, instead of reading from cache, I wanted to get a new response. The solution is to do hard refresh the page.
On MDN Web Docs:
"The HTTP 304 Not Modified client redirection response code indicates that there is no need to retransmit the requested resources. It is an implicit redirection to a cached resource."
Use some preprocessor macro to check if it's in windows or linux. For example
#ifdef WIN32
LIB=
#elif __GNUC__
LIB=wsock32
#endif
include -l$(LIB) in you build command.
You can also specify some command line argument to differentiate both.
I had this same question and this is how I am doing it, from a KafkaConsumer, in Kotlin:
val messageCount = consumer.listTopics().entries.filter { it.key == topicName }
.map {
it.value.map { topicInfo -> TopicPartition(topicInfo.topic(), topicInfo.partition()) }
}.map { consumer.endOffsets(it).values.sum() - consumer.beginningOffsets(it).values.sum()}
.first()
Very rough code, as I just got this to work, but basically you want to subtract the topic's beginning offset from the ending offset and this will be the current message count for the topic.
You can't just rely on the end offset because of other configurations (cleanup policy, retention-ms, etc.) that may end up causing the deletion old messages from your topic. Offsets only "move" forward, so it is the beggining offset that will move forward closer to the end offset (or eventually to the same value, if the topic contains no message right now).
Basically the end offset represents the overall number of messages that went through that topic, and the difference between the two represent the number of messages that the topic contains right now.
nginx also provides the $http_host variable which will pass the port for you. its a concatenation of host and port.
So u just need to do:
proxy_set_header Host $http_host;
You should also consider the OPTIMIZE FOR n ROWS clause. More details on all of this in the DB2 LUW documentation in the Guidelines for restricting SELECT statements topic:

redhat docs are always a great source - good tutorial that explains how to install JDK via yum and then setting the path can be found here (have fun!) - Install OpenJDK and set $JAVA_HOME path
OpenJDK 6:
yum install java-1.6.0-openjdk-devel
OpenJDK 7:
yum install java-1.7.0-openjdk-devel
To list all available java openjdk-devel packages try:
yum list "java-*-openjdk-devel"
Guid.NewGuid()
, as it creates GUIDs as intended.
Guid.NewGuid()
creates an empty Guid
object, initializes it by calling CoCreateGuid
and returns the object.
new Guid()
merely creates an empty GUID (all zeros, I think).
I guess they had to make the constructor public as Guid
is a struct
.
Stored procedure can be called recursively but stored function can not
As Vasil Valchev noted in a comment it is simpler than it looks, but there is a subtle difference that I wasn't noticing in my XML.

Let's say for example in one case, if you want to locked cells from range A1 to I50 then below is the code:
Worksheets("Enter your sheet name").Range("A1:I50").Locked = True
ActiveSheet.Protect Password:="Enter your Password"
In another case if you already have a protected sheet then follow below code:
ActiveSheet.Unprotect Password:="Enter your Password"
Worksheets("Enter your sheet name").Range("A1:I50").Locked = True
ActiveSheet.Protect Password:="Enter your Password"
Enter vault password and inside vault right top corner options icon is there. Press on it. In that ->settings->vault admin rites to be unselected. Work done. U can uninstall app now.
In Android Studio 1.2.2
Say if you want to change com.example.myapp
to org.mydomain.mynewapp
You can follow the steps in each of the directories as displayed in the below screen shot. It will give you the preview option so that you can preview before making any changes.
Go to Refactor -> Rename
and give your new name. You have to do it for each of the folders, say for com, example and myapp. It will automatically update the imports so that you don't have to worry about it.
Also update the file build.gradle
which is not updated automatically.
defaultConfig {
applicationId "org.mydomain.mynewapp" //update the new package name here
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
After that it will ask for sync
do it. Then everything will be fine. I'm able to upload my APK to google store after this. Make sure you have signed your app to upload it to the store.

You don't need jQuery for this. You can use JavaScript's .childNodes.length
.
Just make sure to subtract 1 if you don't want to include the default text node (which is empty by default). Thus, you'd use the following:
var count = elem.childNodes.length - 1;
The first one, ideally with a real link to follow in case the user has JavaScript disabled. Just make sure to return false to prevent the click event from firing if the JavaScript executes.
<a href="#" onclick="myJsFunc(); return false;">Link</a>
If you use Angular2, this way works:
<a [routerLink]="" (click)="passTheSalt()">Click me</a>
.
You should assign an array of char pointers, and then, for each pointer assign enough memory for the string:
char **orderedIds;
orderedIds = malloc(variableNumberOfElements * sizeof(char*));
for (int i = 0; i < variableNumberOfElements; i++)
orderedIds[i] = malloc((ID_LEN+1) * sizeof(char)); // yeah, I know sizeof(char) is 1, but to make it clear...
Seems like a good way to me. Although you perform many mallocs, you clearly assign memory for a specific string, and you can free one block of memory without freeing the whole "string array"
You can't add a list to a set because lists are mutable, meaning that you can change the contents of the list after adding it to the set.
You can however add tuples to the set, because you cannot change the contents of a tuple:
>>> a.add(('f', 'g'))
>>> print a
set(['a', 'c', 'b', 'e', 'd', ('f', 'g')])
Edit: some explanation: The documentation defines a set
as an unordered collection of distinct hashable objects. The objects have to be hashable so that finding, adding and removing elements can be done faster than looking at each individual element every time you perform these operations. The specific algorithms used are explained in the Wikipedia article. Pythons hashing algorithms are explained on effbot.org and pythons __hash__
function in the python reference.
Some facts:
list
: use tuple
insteadset
: use frozenset
insteaddict
: has no official counterpart, but there are some
recipesUsing jQuery
$('#note textarea');
or just
$('#textid');
Consider a scenario where Test1, Test2 and Test3 are three classes. The Test3 class inherits Test2 and Test1 classes. If Test1 and Test2 classes have same method and you call it from child class object, there will be ambiguity to call method of Test1 or Test2 class but there is no such ambiguity for interface as in interface no implementation is there.
It is a way to simplify error checking and avoid deep nested if's. For example:
do {
// do something
if (error) {
break;
}
// do something else
if (error) {
break;
}
// etc..
} while (0);
You have two choices (after logged in).

Selected Answer is not good.
Use pointer-events CSS style. (As Rashad Annara suggested)
See MDN https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events. Its supported in most browsers.
Simple adding "disabled" attribute to anchor will do the job if you have global CSS rule like following:
a[disabled], a[disabled]:hover {
pointer-events: none;
color: #e1e1e1;
}
It's very easy:
numb = raw_input('Input Line: ')
fiIn = open('file.txt').readlines()
for lines in fiIn:
if numb == lines[0]:
print lines
For some unexplained reason this solution doesn't work for me (maybe some incompatibility of types), so I came up with a solution for myself:
HttpResponseMessage response = await client.GetAsync("api/yourcustomobjects");
if (response.IsSuccessStatusCode)
{
var data = await response.Content.ReadAsStringAsync();
var product = JsonConvert.DeserializeObject<Product>(data);
}
This way my content is parsed into a JSON string and then I convert it to my object.
What about using the following:
int number = input.nextInt();
if (number < 0) {
// negative
} else {
// it's a positive
}
This is explained in the official Bootstrap 3 release docs:
Steps to disable responsive views
To disable responsive features, follow these steps. See it in action in the modified template below.
- Remove (or just don't add) the viewport
<meta>
mentioned in the CSS docs- Remove the max-width on the .container for all grid tiers with max-width: none !important; and set a regular width like width: 970px;. Be sure that this comes after the default Bootstrap CSS. You can optionally avoid the !important with media queries or some selector-fu.
- If using navbars, undo all the navbar collapsing and expanding behavior (this is too much to show here, so peep the example).
- For grid layouts, make use of .col-xs-* classes in addition to or in place of the medium/large ones. Don't worry, the extra-small device grid scales up to all resolutions, so you're set there.
You'll still need Respond.js for IE8 (since our media queries are still there and need to be picked up). This just disables the "mobile site" of Bootstrap.
See also the example on GetBootstrap.com/examples/non-responsive/
I found fiddling with styles.xml and activity to be too cumbersome hence created a common utility method which has below options set
Java
Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
window.setStatusBarColor(Color.TRANSPARENT);
Kotlin DSL
activity.window.apply {
clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
statusBarColor = Color.TRANSPARENT
}
And that's all it took to achieve transparent status bar. Hope this helps.
That's because arc4random_uniform() is defined as follows:
func arc4random_uniform(_: UInt32) -> UInt32
It takes a UInt32 as input, and spits out a UInt32. You're attempting to pass it a range of values. arc4random_uniform gives you a random number in between 0 and and the number you pass it (exclusively), so if for example, you wanted to find a random number between -50 and 50, as in [-50, 50]
you could use arc4random_uniform(101) - 50
For me, using Image(fit: BoxFit.fill ...)
worked when in a bounded container.
I don't know specifics of your issue, but if the function needs the value then it can be a parameter passed through the call.
Globals are considered bad because globals state and multiple modifiers can create hard to follow code and strange errors. To many actors fiddling with something can create chaos.
You can try
//ios
shadowOpacity: 0.3,
shadowRadius: 3,
shadowOffset: {
height: 0,
width: 0
},
//android
elevation: 1
SELECT *
FROM
<table_name>
WHERE
<date_field>
BETWEEN
DATE_SUB(NOW(), INTERVAL 1 MONTH) AND NOW();
Similarly, You can select records for 1 month, 2 months etc.
Since arrays must be indexed with integers, the maximum length of an array is Integer.MAX_INT
(231-1, or 2 147 483 647). This is assuming you have enough memory to hold an array of that size, of course.
Try to run below example in order to feel how the magical variables work.
@echo off
SETLOCAL EnableDelayedExpansion
echo Full path and filename: %~f0
echo Drive: %~d0
echo Path: %~p0
echo Drive and path: %~dp0
echo Filename without extension: %~n0
echo Filename with extension: %~nx0
echo Extension: %~x0
echo date time : %~t0
echo file size: %~z0
ENDLOCAL
The related rules are following.
%~I - expands %I removing any surrounding quotes ("")
%~fI - expands %I to a fully qualified path name
%~dI - expands %I to a drive letter only
%~pI - expands %I to a path only
%~nI - expands %I to a file name only
%~xI - expands %I to a file extension only
%~sI - expanded path contains short names only
%~aI - expands %I to file attributes of file
%~tI - expands %I to date/time of file
%~zI - expands %I to size of file
%~$PATH:I - searches the directories listed in the PATH
environment variable and expands %I to the
fully qualified name of the first one found.
If the environment variable name is not
defined or the file is not found by the
search, then this modifier expands to the
empty string
I had this issue, I logged in as administrator and it fixed the issue.
If you're mutating your source object, ES6 can do it in one line.
delete Object.assign(o, {[newKey]: o[oldKey] })[oldKey];
Or two lines if you want to create a new object.
const newObject = {};
delete Object.assign(newObject, o, {[newKey]: o[oldKey] })[oldKey];
I realize I am a little late here, (5 years or so), but I think there is a better answer than the accepted one as follows:
$("#addComment").click(function() {
if(typeof TinyMCE === "undefined") {
$.ajax({
url: "tinymce.js",
dataType: "script",
cache: true,
success: function() {
TinyMCE.init();
}
});
}
});
The getScript()
function actually prevents browser caching. If you run a trace you will see the script is loaded with a URL that includes a timestamp parameter:
http://www.yoursite.com/js/tinymce.js?_=1399055841840
If a user clicks the #addComment
link multiple times, tinymce.js
will be re-loaded from a differently timestampped URL. This defeats the purpose of browser caching.
===
Alternatively, in the getScript()
documentation there is a some sample code that demonstrates how to enable caching by creating a custom cachedScript()
function as follows:
jQuery.cachedScript = function( url, options ) {
// Allow user to set any option except for dataType, cache, and url
options = $.extend( options || {}, {
dataType: "script",
cache: true,
url: url
});
// Use $.ajax() since it is more flexible than $.getScript
// Return the jqXHR object so we can chain callbacks
return jQuery.ajax( options );
};
// Usage
$.cachedScript( "ajax/test.js" ).done(function( script, textStatus ) {
console.log( textStatus );
});
===
Or, if you want to disable caching globally, you can do so using ajaxSetup()
as follows:
$.ajaxSetup({
cache: true
});
@allain, @GateKiller your query selects users not logins
To select logins you can use this query:
SELECT name FROM master..sysxlogins WHERE sid IS NOT NULL
In MSSQL2005/2008 syslogins table is used insted of sysxlogins
Your query contains columns which could be present with the same name in more than one table you are referencing, hence the not unique error. It's best if you make the references explicit and/or use table aliases when joining.
Try
SELECT pa.ProjectID, p.Project_Title, a.Account_ID, a.Username, a.Access_Type, c.First_Name, c.Last_Name
FROM Project_Assigned pa
INNER JOIN Account a
ON pa.AccountID = a.Account_ID
INNER JOIN Project p
ON pa.ProjectID = p.Project_ID
INNER JOIN Clients c
ON a.Account_ID = c.Account_ID
WHERE a.Access_Type = 'Client';
If you look at the PHP constant PATH_SEPARATOR, you will see it being ":" for you.
If you break apart your string ".:/usr/share/pear:/usr/share/php" using that character, you will get 3 parts.
Any attempts to include()/require() things, will look in these directories, in this order.
It is showing you that in the error message to let you know where it could NOT find the file you were trying to require()
For your first require, if that is being included from your index.php, then you dont need the dir stuff, just do...
require_once ( 'db/config.php');
Windows only: You can either use Ironpython or a library that allows cPython to access the .NET frameworks on Windows. Then use the sendkeys class of .NET or the more general send to simulate a keystroke.
OS X only: Use PyObjC then use use CGEventCreateKeyboardEvent
call.
Full disclosure: I have only done this on OS X with Python, but I have used .NET sendkeys (with C#) and that works great.
Vertical align doesn't quite work the way you want it to. See: http://phrogz.net/css/vertical-align/index.html
This isn't pretty, but it WILL do what you want: Vertical align behaves as expected only when used in a table cell.
There are other alternatives: You can declare things as tables or table cells within CSS to make them behave as desired, for example. Margins and positioning can sometimes be played with to get the same effect. None of the solutions are terrible pretty, though.
Use this line to get the division behavior you want:
from __future__ import division
Alternatively, you could use modulus:
if (a % b) == 0: #do something
For future visitors: In the new HttpClient
(Angular 4.3+), the response
object is JSON by default, so you don't need to do response.json().data
anymore. Just use response
directly.
Example (modified from the official documentation):
import { HttpClient } from '@angular/common/http';
@Component(...)
export class YourComponent implements OnInit {
// Inject HttpClient into your component or service.
constructor(private http: HttpClient) {}
ngOnInit(): void {
this.http.get('https://api.github.com/users')
.subscribe(response => console.log(response));
}
}
Don't forget to import it and include the module under imports in your project's app.module.ts:
...
import { HttpClientModule } from '@angular/common/http';
@NgModule({
imports: [
BrowserModule,
// Include it under 'imports' in your application module after BrowserModule.
HttpClientModule,
...
],
...
UNIX timestamp it is count of seconds from 1970, so you need to convert it to JS Date object:
var date = new Date(unixTimestamp*1000);
There's an easier way:
find ... | while read -r file; do
echo "look at my $file, my $file is amazing";
done
Alternatively:
while read -r file; do
echo "look at my $file, my $file is amazing";
done <<< "$(find ...)"
You need to use the scrollTop
property.
document.getElementById('box').scrollTop
Use mb_convert_encoding to convert an ASCII to UTF-8. More info here
$string = "chárêctërs";
print(mb_detect_encoding ($string));
$string = mb_convert_encoding($string, "UTF-8");
print(mb_detect_encoding ($string));
If
should be if
. Your program should look like this:
answer = raw_input("Is the information correct? Enter Y for yes or N for no")
if answer.upper() == 'Y':
print("this will do the calculation")
else:
exit()
Note also that the indentation is important, because it marks a block in Python.
Here is how to clear all trash & caches (without other private data in browsers) by a command line. This is a command line batch script that takes care of all trash (as of April 2014):
erase "%TEMP%\*.*" /f /s /q
for /D %%i in ("%TEMP%\*") do RD /S /Q "%%i"
erase "%TMP%\*.*" /f /s /q
for /D %%i in ("%TMP%\*") do RD /S /Q "%%i"
erase "%ALLUSERSPROFILE%\TEMP\*.*" /f /s /q
for /D %%i in ("%ALLUSERSPROFILE%\TEMP\*") do RD /S /Q "%%i"
erase "%SystemRoot%\TEMP\*.*" /f /s /q
for /D %%i in ("%SystemRoot%\TEMP\*") do RD /S /Q "%%i"
@rem Clear IE cache - (Deletes Temporary Internet Files Only)
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8
erase "%LOCALAPPDATA%\Microsoft\Windows\Tempor~1\*.*" /f /s /q
for /D %%i in ("%LOCALAPPDATA%\Microsoft\Windows\Tempor~1\*") do RD /S /Q "%%i"
@rem Clear Google Chrome cache
erase "%LOCALAPPDATA%\Google\Chrome\User Data\*.*" /f /s /q
for /D %%i in ("%LOCALAPPDATA%\Google\Chrome\User Data\*") do RD /S /Q "%%i"
@rem Clear Firefox cache
erase "%LOCALAPPDATA%\Mozilla\Firefox\Profiles\*.*" /f /s /q
for /D %%i in ("%LOCALAPPDATA%\Mozilla\Firefox\Profiles\*") do RD /S /Q "%%i"
pause
I am pretty sure it will run for some time when you first run it :) Enjoy!
What about support for border radius AND background gradient. Yes IE9 is to support them both seperately but if you mix the two the gradient bleeds out of the rounded corner. Below is a link to a poor example but i have seen it in my own testing as well. Should of taken a screen shot :(
Maybe the real question is when will IE support CSS standards without MS-FILTER proprietary hacks.

REST stands for REpresentational State Transfer and goes a little something like this:
We have a bunch of uniquely addressable 'entities' that we want made available via a web application. Those entities each have some identifier and can be accessed in various formats. REST defines a bunch of stuff about what GET, POST, etc mean for these purposes.
the basic idea with REST is that you can attach a bunch of 'renderers' to different entities so that they can be available in different formats easily using the same HTTP verbs and url formats.
For more clarification on what RESTful means and how it is used google rails. Rails is a RESTful framework so there's loads of good information available in its docs and associated blog posts. Worth a read even if you arent keen to use the framework. For example: http://www.sitepoint.com/restful-rails-part-i/
RESTless means not restful. If you have a web app that does not adhere to RESTful principles then it is not RESTful
You can sets the body's background colour using document.body.style.backgroundColor = "red";
so this can be put into a function that's called when the user clicks.
The next part can be done by using document.getElementByID("divID").style.backgroundColor = "red";
window.setTimeout("yourFunction()",10000);
which calls yourFunction in 10 seconds to change the colour back.

SSL certificates are bound to a 'common name', which is usually a fully qualified domain name but can be a wildcard name (eg. *.domain.com) or even an IP address, but it usually isn't.
In your case, you are accessing your LDAP server by a hostname and it sounds like your two LDAP servers have different SSL certificates installed. Are you able to view (or download and view) the details of the SSL certificate? Each SSL certificate will have a unique serial numbers and fingerprint which will need to match. I assume the certificate is being rejected as these details don't match with what's in your certificate store.
Your solution will be to ensure that both LDAP servers have the same SSL certificate installed.
BTW - you can normally override DNS entries on your workstation by editing a local 'hosts' file, but I wouldn't recommend this.
I'm not sure if this approach has been taken but a work around i'm using is:
from multiprocessing import Pool
t = None
def run(n):
return t.f(n)
class Test(object):
def __init__(self, number):
self.number = number
def f(self, x):
print x * self.number
def pool(self):
pool = Pool(2)
pool.map(run, range(10))
if __name__ == '__main__':
t = Test(9)
t.pool()
pool = Pool(2)
pool.map(run, range(10))
Output should be:
0

It does exactly what you need and has these features:
Range("A1").value = Environ("Username")
This is better than Application.Username
, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.
Application Username
is the name of the User set in Excel > Tools > Options Environ("Username")
is the name you registered for Windows; see Control Panel >SystemCreate a Jenkins Job that runs on Master:
java -jar "%JENKINS_HOME%/war/WEB-INF/jenkins-cli.jar" -s "%JENKINS_URL%" safe-restart

SqlDeveloper stores all the connections in a file named
connections.xml
In windows XP you can find the file in location
C:\Documents and Settings\<username>\Application Data\SQL Developer\systemX.X.X.X.X\o.jdeveloper.db.connection.X.X.X.X.X.X.X\connections.xml
In Windows 7 you will find it in location

This is a favorite Java interview question.
Thread t1 = new Thread(new EventThread("e1"));
t1.start();
Thread e2 = new Thread(new EventThread("e2"));
t2.start();
while (true) {
try {
t1.join(); // 1
t2.join(); // 2 These lines (1,2) are in in public static void main
break;
}
}
t1.join()
means, t1 says something like "I want to finish first". Same is the case with t2
. No matter who started t1
or t2
thread (in this case the main
method), main will wait until t1
and t2
finish their task.
However, an important point to note down, t1
and t2
themselves can run in parallel irrespective of the join call sequence on t1
and t2
. It is the main/daemon
thread that has to wait.
To add to the other answers, here are the variable list from Python Documentation.

Your regex looks correct, but you're splitting
with it instead of matching
with it. You want something like this:
// Untested code
Matcher matcher = Pattern.compile("<%=(.*?)%>").matcher(str);
while (matcher.find()) {
System.out.println(matcher.group());
}
Maybe you could use:
select last_name+', '+first_name
from user_mstr
where ',' + @user_id_list + ',' like '%,' + convert(nvarchar, user_id) + ',%'
the above approach didn't work for me on Android Studio 3.0. It still shows the background. I just made an empty background file
<?xml version="1.0" encoding="utf-8"?>
<vector
android:height="108dp"
android:width="108dp"
android:viewportHeight="108"
android:viewportWidth="108"
xmlns:android="http://schemas.android.com/apk/res/android">
</vector>
This worked except the full bleed layers
To note it in the languages you mentioned:
Java:
String str = new String("Hello");
Python:
str = "Hello"
Both Java and Python have the concept of a "string", C does not have the concept of a "string". C has character arrays which can come in "read only" or manipulatable.
C:
char * str = "Hello"; // the string "Hello\0" is pointed to by the character pointer
// str. This "string" can not be modified (read only)
or
char str[] = "Hello"; // the characters: 'H''e''l''l''o''\0' have been copied to the
// array str. You can change them via: str[x] = 't'
A character array is a sequence of contiguous characters with a unique sentinel character at the end (normally a NULL terminator '\0'
). Note that the sentinel character is auto-magically appended for you in the cases above.
No, that's not really possible, as
The goal of the MD5 and its family of hashing functions is
Think that you can get the MD5 of any string, even very long. And the MD5 is only 16 bytes long (32 if you write it in hexa to store or distribute it more easily). If you could reverse them, you'd have a magical compacting scheme.
This being said, as there aren't so many short strings (passwords...) used in the world, you can test them from a dictionary (that's called "brute force attack") or even google for your MD5. If the word is common and wasn't salted, you have a reasonable chance to succeed...
List<String> sids = new ArrayList<String>();
List<String> lids = new ArrayList<String>();
String query = "SELECT rlink_id, COUNT(*)"
+ "FROM dbo.Locate "
+ "GROUP BY rlink_id ";
Statement stmt = yourconnection.createStatement();
try {
ResultSet rs4 = stmt.executeQuery(query);
while (rs4.next()) {
sids.add(rs4.getString(1));
lids.add(rs4.getString(2));
}
} finally {
stmt.close();
}
String show[] = sids.toArray(sids.size());
String actuate[] = lids.toArray(lids.size());
Use zip(*list)
:
>>> l = [(1,2), (3,4), (8,9)]
>>> list(zip(*l))
[(1, 3, 8), (2, 4, 9)]
The zip()
function pairs up the elements from all inputs, starting with the first values, then the second, etc. By using *l
you apply all tuples in l
as separate arguments to the zip()
function, so zip()
pairs up 1
with 3
with 8
first, then 2
with 4
and 9
. Those happen to correspond nicely with the columns, or the transposition of l
.
zip()
produces tuples; if you must have mutable list objects, just map()
the tuples to lists or use a list comprehension to produce a list of lists:
map(list, zip(*l)) # keep it a generator
[list(t) for t in zip(*l)] # consume the zip generator into a list of lists
For those who just need to join one level below at the top.
Being clearer, how transform this:
Array
(
[0] => Array
(
[0] => Array
(
[id] => 001
)
[1] => Array
(
[id] => 005
)
)
[1] => Array
(
[0] => Array
(
[id] => 007
)
[1] => Array
(
[id] => 009
)
)
)
On this:
Array
(
[0] => Array
(
[0] => Array
(
[id] => 001
)
[1] => Array
(
[id] => 005
)
[2] => Array
(
[id] => 007
)
[3] => Array
(
[id] => 009
)
)
)
The (simple) code:
foreach ($multi_array as $key => $reduced_array) {
foreach ($reduced_array as $key => $value) {
$new_array[] = $value;
}
}
With so many functions available, sometimes we forget that we can do something with a simple code ...
If try-except-finally is nested inside a finally block, the result from "child" finally is preserved. I have not found an official explanation yet, but the following code snippet shows this behavior in Python 3.6.
def f2():
try:
a = 4
raise SyntaxError
except SyntaxError as se:
print('log SE')
raise se from None
finally:
try:
raise ValueError
except ValueError as ve:
a = 5
print('log VE')
raise ve from None
finally:
return 6
return a
In [1]: f2()
log SE
log VE
Out[2]: 6
If you've applied the CORS middleware and it's still not working, try this.
If the route for your API is:
Route::post("foo", "MyController"})->middleware("cors");
Then you need to change it to allow for the OPTIONS method:
Route::match(['post', 'options'], "foo", "MyController")->middleware("cors");
And here's an example of the customizer implemented in Groovy:
Shouldn't you also be using the jspdf.plugin.from_html.js library? Besides the main library (jspdf.js), you must use other libraries for "special operations" (like jspdf.plugin.addimage.js for using images). Check https://github.com/MrRio/jsPDF.
If you need to treat empty columns as NULL
s, try this:
SELECT CAST(nullif(<column>, '') AS integer);
On the other hand, if you do have NULL
values that you need to avoid, try:
SELECT CAST(coalesce(<column>, '0') AS integer);
I do agree, error message would help a lot.
It's very easy to write in PHP using strlen
and strpos
functions:
function isRotation($string1, $string2) {
return strlen($string1) == strlen($string2) && (($string1.$string1).strpos($string2) != -1);
}
I don't know what strpos
uses internally, but if it uses KMP this will be linear in time.
at version 4.0 or above, we need to create one 'config.inc.php' or rename the 'config.sample.inc.php' to 'config.inc.php';
In my case, I also work with one mysql server for each environment (dev and production):
/* others code*/
$whoIam = gethostname();
switch($whoIam) {
case 'devHost':
$cfg['Servers'][$i]['host'] = 'localhost';
break;
case 'MasterServer':
$cfg['Servers'][$i]['host'] = 'masterMysqlServer';
break;
} /* others code*/
As of Android 3.0 (API Level 11) Android has a more recent and improved JSON Parser.
http://developer.android.com/reference/android/util/JsonReader.html
Reads a JSON (RFC 4627) encoded value as a stream of tokens. This stream includes both literal values (strings, numbers, booleans, and nulls) as well as the begin and end delimiters of objects and arrays. The tokens are traversed in depth-first order, the same order that they appear in the JSON document. Within JSON objects, name/value pairs are represented by a single token.
Escaping quotes in VB6 or VBScript strings is simple in theory although often frightening when viewed. You escape a double quote with another double quote.
An example:
"c:\program files\my app\app.exe"
If I want to escape the double quotes so I could pass this to the shell execute function listed by Joe or the VB6 Shell function I would write it:
escapedString = """c:\program files\my app\app.exe"""
How does this work? The first and last quotes wrap the string and let VB know this is a string. Then each quote that is displayed literally in the string has another double quote added in front of it to escape it.
It gets crazier when you are trying to pass a string with multiple quoted sections. Remember, every quote you want to pass has to be escaped.
If I want to pass these two quoted phrases as a single string separated by a space (which is not uncommon):
"c:\program files\my app\app.exe" "c:\documents and settings\steve"
I would enter this:
escapedQuoteHell = """c:\program files\my app\app.exe"" ""c:\documents and settings\steve"""
I've helped my sysadmins with some VBScripts that have had even more quotes.
It's not pretty, but that's how it works.
The text inside $type is substituted directly into the insert string, therefore MySQL gets this:
... VALUES(testing, 'john', 'whatever')
Notice that there are no quotes around testing, you need to put these in like so:
$type = 'testing';
mysql_query("INSERT INTO contents (type, reporter, description) VALUES('$type', 'john', 'whatever')");
I also recommend you read up on SQL injection, as this sort of parameter passing is prone to hacking attempts if you do not sanitize the data being used:
you can check out this set of classes: https://code.google.com/p/minify/source/browse/?name=master#git%2Fmin%2Flib%2FMinify , you'll find html/css/js minification classes there.
you can also try this: http://code.google.com/p/htmlcompressor/
Good luck :)
This can be done by setting table-cell style to width: auto
, and content empty. The columns are now equal-wide, but holding no content.
To insert content to the cell, add an div
with css:
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
You also need to add position: relative
to the cells.
Now you can put the actual content into the div talked above.
if your application accepts errors raise from Oracle, then you can use it. we have an application, each time when an error happens, we call raise_application_error, the application will popup a red box to show the error message we provide through this method.
When using dotnet code, I just use "raise", dotnet exception mechanisim will automatically capture the error passed by Oracle ODP and shown inside my catch exception code.
JSch library is the powerful library that can be used to read file from SFTP server. Below is the tested code to read file from SFTP location line by line
JSch jsch = new JSch();
Session session = null;
try {
session = jsch.getSession("user", "127.0.0.1", 22);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword("password");
session.connect();
Channel channel = session.openChannel("sftp");
channel.connect();
ChannelSftp sftpChannel = (ChannelSftp) channel;
InputStream stream = sftpChannel.get("/usr/home/testfile.txt");
try {
BufferedReader br = new BufferedReader(new InputStreamReader(stream));
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch (IOException io) {
System.out.println("Exception occurred during reading file from SFTP server due to " + io.getMessage());
io.getMessage();
} catch (Exception e) {
System.out.println("Exception occurred during reading file from SFTP server due to " + e.getMessage());
e.getMessage();
}
sftpChannel.exit();
session.disconnect();
} catch (JSchException e) {
e.printStackTrace();
} catch (SftpException e) {
e.printStackTrace();

For linux/unix, I can suggest unix package.
To increase the memory limit in linux:
install.packages("unix")
library(unix)
rlimit_as(1e12) #increases to ~12GB
You can also check the memory with this:
rlimit_all()
for detailed information: https://rdrr.io/cran/unix/man/rlimit.html
also you can find further info here: limiting memory usage in R under linux
I was searching for this very same thing. I had read that this was available in Bootstrap 3.0, but I was having no luck in actually implementing it. This is what I came up with and it works great. Very simple jQuery and Javascript.
Here is the JSFiddle to play around with... http://jsfiddle.net/CriddleCraddle/Wj9dD/
The solution is very similar to other solutions on the web and StackOverflow. If you do not find this one useful, search for what you need. Goodluck!
Here is the HTML...
<div id="banner">
<h2>put what you want here</h2>
<p>just adjust javascript size to match this window</p>
</div>
<nav id='nav_bar'>
<ul class='nav_links'>
<li><a href="url">Sign In</a></li>
<li><a href="url">Blog</a></li>
<li><a href="url">About</a></li>
</ul>
</nav>
<div id='body_div'>
<p style='margin: 0; padding-top: 50px;'>and more stuff to continue scrolling here</p>
</div>
Here is the CSS...
html, body {
height: 4000px;
}
.navbar-fixed {
top: 0;
z-index: 100;
position: fixed;
width: 100%;
}
#body_div {
top: 0;
position: relative;
height: 200px;
background-color: green;
}
#banner {
width: 100%;
height: 273px;
background-color: gray;
overflow: hidden;
}
#nav_bar {
border: 0;
background-color: #202020;
border-radius: 0px;
margin-bottom: 0;
height: 30px;
}
//the below css are for the links, not needed for sticky nav
.nav_links {
margin: 0;
}
.nav_links li {
display: inline-block;
margin-top: 4px;
}
.nav_links li a {
padding: 0 15.5px;
color: #3498db;
text-decoration: none;
}
Now, just add the javacript to add and remove the fix class based on the scroll position.
$(document).ready(function() {
//change the integers below to match the height of your upper div, which I called
//banner. Just add a 1 to the last number. console.log($(window).scrollTop())
//to figure out what the scroll position is when exactly you want to fix the nav
//bar or div or whatever. I stuck in the console.log for you. Just remove when
//you know the position.
$(window).scroll(function () {
console.log($(window).scrollTop());
if ($(window).scrollTop() > 550) {
$('#nav_bar').addClass('navbar-fixed-top');
}
if ($(window).scrollTop() < 551) {
$('#nav_bar').removeClass('navbar-fixed-top');
}
});
});
I found using jQuery was my best solution.
$( "#my_number_field" ).blur(function() {
this.value = parseFloat(this.value).toFixed(2);
});
You can see the information regarding the transfer by doing:
curl_setopt($curl_exect, CURLINFO_HEADER_OUT, true);
before the request, and
$information = curl_getinfo($curl_exect);
after the request
View: http://www.php.net/manual/en/function.curl-getinfo.php
You can also use the CURLOPT_HEADER
in your curl_setopt
curl_setopt($curl_exect, CURLOPT_HEADER, true);
$httpcode = curl_getinfo($c, CURLINFO_HTTP_CODE);
return $httpcode == 200;
These are just some methods of using the headers.
If your page is missing meta[@name="viewport"]
element within its DOM, then the following could be used to detect a mobile device:
@media only screen and (width: 980px), (hover: none) { … }
If you want to avoid false-positives with desktops that just magically have their viewport set to 980px like all the mobile browsers do, then a device-width
test could also be added into the mix:
@media only screen and (max-device-width: 800px) and (width: 980px), (hover: none) { … }
Per the list at https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries, the new hover
property would appear to be the final new way to detect that you've got yourself a mobile device that doesn't really do proper hover
; it's only been introduced in 2018 with Firefox 64 (2018), although it's been supported since 2016 with Android Chrome 50 (2016), or even since 2014 with Chrome 38 (2014):
Rene, your HOME
variable isn't set correctly. Either change it to c:\Users\(your-username)
or just to %USERNAME%
.
You can get everything through ExternalContext
. In JSF 1.x, you can get the raw HttpServletResponse
object by ExternalContext#getResponse()
. In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream()
without the need to grab the HttpServletResponse
from under the JSF hoods.
On the response, you should set the Content-Type
header so that the client knows which application to associate with the provided file. And, you should set the Content-Length
header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition
header to attachment
if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.
Most important part is to call FacesContext#responseComplete()
to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException
with a message like getoutputstream() has already been called for this response
when the JSF implementation calls getWriter()
to render HTML.
You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink>
and <h:commandButton>
. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.
In case you're using e.g. PrimeFaces <p:commandXxx>
, then you need to make sure that you explicitly turn off ajax via ajax="false"
attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" />
in the command component.
public void download() throws IOException {
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.
OutputStream output = ec.getResponseOutputStream();
// Now you can write the InputStream of the file to the above OutputStream the usual way.
// ...
fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.

In case you need to stream a static file from the local disk file system, substitute the code as below:
File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();
// ...
Files.copy(file.toPath(), output);
In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output
there where the API being used expects an OutputStream
.
E.g. iText PDF:
String fileName = "dynamic.pdf";
String contentType = "application/pdf";
// ...
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();
E.g. Apache POI HSSF:
String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";
// ...
HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();
Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.
If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile()
methods taking either a File
, or an InputStream
, or a byte[]
, and specifying whether the file should be downloaded as an attachment (true
) or inline (false
).
public void download() throws IOException {
Faces.sendFile(file, true);
}
Yes, this code is complete as-is. You don't need to invoke responseComplete()
and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.
An id in a route should be viewed the same as an index to a list, and naming should proceed accordingly.
numbers = [1, 2, 3]
numbers GET /numbers
numbers[1] GET /numbers/1
numbers.push(4) POST /numbers
numbers[1] = 23 UPDATE /numbers/1
But some resources don't use ids in their routes because there's either only one, or a user never has access to more than one, so those aren't lists:
GET /dashboard
DELETE /session
POST /login
GET /users/{:id}/profile
UPDATE /users/{:id}/profile
This is the modern browser way, without 3rd party libraries. Works on all the latest browsers.

1. Installing OpenCV 2.4.3
First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\
.
Wait until all files get extracted. It will create a new directory C:\opencv
which
contains OpenCV header files, libraries, code samples, etc.
Now you need to add the directory C:\opencv\build\x86\vc10\bin
to your system PATH. This directory contains OpenCV DLLs required for running your code.
Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...
On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin;
(3), then click Ok.
On some computers, you may need to restart your computer for the system to recognize the environment path variables.
This will completes the OpenCV 2.4.3 installation on your computer.
2. Create a new project and set up Visual C++
Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest
) and set the project location (e.g: c:\projects
).
Click Ok. Visual C++ will create an empty project.
Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest
and select Properties → VC++ Directories.
Select Include Directories to add a new entry and type C:\opencv\build\include
.
Click Ok to close the dialog.
Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib
.
Click Ok to close the dialog.
Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:
opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib
Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).
Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.
NOTE:
These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:
opencv_core243.lib
opencv_imgproc243.lib
...
instead of:
opencv_core243d.lib
opencv_imgproc243d.lib
...
You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.
Name your file (e.g: loadimg.cpp
) and click Ok. Type the code below in the editor:
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
Mat im = imread("c:/full/path/to/lena.jpg");
if (im.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
imshow("Image", im);
waitKey(0);
}
The code above will load c:\full\path\to\lena.jpg
and display the image. You can
use any image you like, just make sure the path to the image is correct.
Type F5 to compile the code, and it will display the image in a nice window.
And that is your first OpenCV program!
3. Where to go from here?
Now that your OpenCV environment is ready, what's next?
c:\opencv\samples\cpp
.Just style the border of the rows:
?table tr {
border-bottom: 1px solid black;
}?
table tr:last-child {
border-bottom: none;
}
Here is a fiddle.
Edited as mentioned by @pkyeck. The second style avoids the line under the last row. Maybe you are looking for this.
For the former, convention over configuration. Rails default when you reference another table with
belongs_to :something
is to look for something_id
.
references
, or belongs_to
is actually newer way of writing the former with few quirks.
Important is to remember that it will not create foreign keys for you. In order to do that, you need to set it up explicitly using either:
t.references :something, foreign_key: true
t.belongs_to :something_else, foreign_key: true
or (note the plural):
add_foreign_key :table_name, :somethings
add_foreign_key :table_name, :something_elses`
Add this code in the Module :
Public Sub ClearTextBoxes(frm As Form)
For Each Control In frm.Controls
If TypeOf Control Is TextBox Then
Control.Text = "" 'Clear all text
End If
Next Control
End Sub
Add this code in the Form window to Call the Sub routine:
Private Sub Command1_Click()
Call ClearTextBoxes(Me)
End Sub
It should respond to ActionListeners, like this:
combo.addActionListener (new ActionListener () {
public void actionPerformed(ActionEvent e) {
doSomething();
}
});
@John Calsbeek rightly points out that addItemListener()
will work, too. You may get 2 ItemEvents
, though, one for the deselection of the previously selected item, and another for the selection of the new item. Just don't use both event types!
This answer is similar to others with requests
and BeautifulSoup
, but using list comprehension.
Because find_all()
is the most popular method in the Beautiful Soup search API, you can use soup("a")
as a shortcut of soup.findAll("a")
and using list comprehension:
import requests
from bs4 import BeautifulSoup
URL = "http://www.yourwebsite.com"
page = requests.get(URL)
soup = BeautifulSoup(page.content, features='lxml')
# Find links
all_links = [link.get("href") for link in soup("a")]
# Only external links
ext_links = [link.get("href") for link in soup("a") if "http" in link.get("href")]

Repairing Visual Studio 2015 seems to have resolved this issue for me. See this issue for NuGet in GitHub.
Try This:
var trident = !!navigator.userAgent.match(/Trident\/7.0/);
var net = !!navigator.userAgent.match(/.NET4.0E/);
var IE11 = trident && net
var IEold = ( navigator.userAgent.match(/MSIE/i) ? true : false );
if(IE11 || IEold){
alert("IE")
}else{
alert("Other")
}
FragmentPagerAdapter is the factory of the fragments. To find a fragment based on its position if still in memory use this:
public Fragment findFragmentByPosition(int position) {
FragmentPagerAdapter fragmentPagerAdapter = getFragmentPagerAdapter();
return getSupportFragmentManager().findFragmentByTag(
"android:switcher:" + getViewPager().getId() + ":"
+ fragmentPagerAdapter.getItemId(position));
}
Sample code for v4 support api.
I believe that this is one the most elegant solution.
import os
if os.name == 'nt':
import msvcrt
def getch():
return msvcrt.getch().decode()
else:
import sys, tty, termios
fd = sys.stdin.fileno()
old_settings = termios.tcgetattr(fd)
def getch():
try:
tty.setraw(sys.stdin.fileno())
ch = sys.stdin.read(1)
finally:
termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)
return ch
and then use it in the code:
if getch() == chr(ESC_ASCII_VALUE):
print("ESC!")
This check is compatible with both Python 2.x and Python 3.x.
import six
isinstance(obj, six.class_types)
This is basically a wrapper function that performs the same check as in andrea_crotti answer.
Example:
>>> import datetime
>>> isinstance(datetime.date, six.class_types)
>>> True
>>> isinstance(datetime.date.min, six.class_types)
>>> False
There is another issue to be considered here. Some people expect that adding custom method to your repository will automatically expose them as REST services under '/search' link. This is unfortunately not the case. Spring doesn't support that currently.
This is 'by design' feature, spring data rest explicitly checks if method is a custom method and doesn't expose it as a REST search link:
private boolean isQueryMethodCandidate(Method method) {
return isQueryAnnotationPresentOn(method) || !isCustomMethod(method) && !isBaseClassMethod(method);
}
This is a qoute of Oliver Gierke:
This is by design. Custom repository methods are no query methods as they can effectively implement any behavior. Thus, it's currently impossible for us to decide about the HTTP method to expose the method under. POST would be the safest option but that's not in line with the generic query methods (which receive GET).
For more details see this issue: https://jira.spring.io/browse/DATAREST-206
AFNetworking provides async image loading into a UIImageView with placeholder support. It also supports async networking for working with APIs in general.
$("#btnId").click(function(e){
e.preventDefault();
$.ajax({
...
beforeSend : function(xhr, opts){
//show loading gif
},
success: function(){
},
complete : function() {
//remove loading gif
}
});
});
Postgres hasn't implemented an equivalent to INSERT OR REPLACE
. From the ON CONFLICT
docs (emphasis mine):
It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.
Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE
applies more generally, since it lets you set new values based on preexisting data. For example:
INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;
Although there are many acceptable answers in response to this question, I don't see any examples of the sub
method using the \Datetime
object: https://www.php.net/manual/en/datetime.sub.php
So, for reference, you can also use a \DateInterval
to modify a \Datetime
object:
$date = new \DateTime('2009-01-01');
$date->sub(new \DateInterval('P1Y'));
echo $date->format('Y-m-d');
Which returns:
2008-01-01
For more information about \DateInterval
, refer to the documentation: https://www.php.net/manual/en/class.dateinterval.php
If you're still having issues with the simple approach, creating an empty bucket then Redirect all requests to another host name
under Static web hosting in properties via the console. Ensure that you have set 2 A records in route53, one for final-destination.com
and one for redirect-to.final-destination.com
. The settings for each of these will be identical, but the name will be different so it matches the names that you set for your buckets / URLs.

Implement INotifyPropertyChanged
in your class.
Specify a callback in the property metadata when you register the dependency property.
In the callback, raise the PropertyChanged
event.
Adding the callback:
public static DependencyProperty FirstProperty = DependencyProperty.Register(
"First",
typeof(string),
typeof(MyType),
new FrameworkPropertyMetadata(
false,
new PropertyChangedCallback(OnFirstPropertyChanged)));
Raising PropertyChanged
in the callback:
private static void OnFirstPropertyChanged(
DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
PropertyChangedEventHandler h = PropertyChanged;
if (h != null)
{
h(sender, new PropertyChangedEventArgs("Second"));
}
}
You can use the following two properties in "colors.xml"
<color name="colorControlNormal">#eeeeee</color>
<color name="colorControlActivated">#eeeeee</color>
colorControlNormal is for the normal view of checkbox, and colorControlActivated is for when the checkbox is checked.
I want a random number between 0 and 1, like 0.3452
random.random()
is what you are looking for:
From python docs: random.random() Return the next random floating point number in the range [0.0, 1.0).
And, btw, Why your try didn't work?:
Your try was: random.randrange(0, 1)
From python docs: random.randrange() Return a randomly selected element from range(start, stop, step). This is equivalent to choice(range(start, stop, step)), but doesn’t actually build a range object.
So, what you are doing here, with random.randrange(a,b)
is choosing a random element from range(a,b)
; in your case, from range(0,1)
, but, guess what!: the only element in range(0,1)
, is 0
, so, the only element you can choose from range(0,1)
, is 0
; that's why you were always getting 0
back.
To clarify for anyone who is looking for what is the difference between the 3 on a simpler level. You can expose your service with minimal ClusterIp (within k8s cluster) or larger exposure with NodePort (within cluster external to k8s cluster) or LoadBalancer (external world or whatever you defined in your LB).
ClusterIp exposure < NodePort exposure < LoadBalancer exposure

As indicated by @TerryA, many answers discuss how to find one index.
more_itertools
is a third-party library with tools to locate multiple indices within an iterable.
Given
import more_itertools as mit
iterable = ["foo", "bar", "baz", "ham", "foo", "bar", "baz"]
Code
Find indices of multiple observations:
list(mit.locate(iterable, lambda x: x == "bar"))
# [1, 5]
Test multiple items:
list(mit.locate(iterable, lambda x: x in {"bar", "ham"}))
# [1, 3, 5]
See also more options with more_itertools.locate
. Install via > pip install more_itertools
.
I had to uninstall my anti virus! Before uninstalling I clicked on the option where it said to disable auto-protect for 15 min. I also clicked on another option that supposibly disabled the anti-virus. That still was blocking my server! I don't understand why Norton makes it so hard to literally stop doing everything it's doing. I know I could had solve it by adding an exception to the firewall but Norton was taking care of windows firewall as well.
Looks like I'm a bit late but for others with this issue try this code
p { font-size: 3vmax; }
use whatever tag you prefer and size you prefer (replace the 3)
p { font-size: 3vmin; }
is used for a max size.
You can do this. Adapt it to your situation:
for l in Nlist:
for item in l:
print item
-May be the problem is that you have deleted .java files doing this doesn't delete the .XML files so go to res-> layout and delete those .XML files that you had delete before. -the another problem may be you haven't delete the files that is present in manifests under syntax that you deleted recently... So delete and run the code
You can create an empty vector like so
vec <- numeric(0)
And then add elements using c()
vec <- c(vec, 1:5)
However as romunov says, it's much better to pre-allocate a vector and then populate it (as this avoids reallocating a new copy of your vector every time you add elements)
Swift 3 & 4 & 4.2 & 5
Locale.current.languageCode
does not compile regularly. Because you did not implemented localization for your project.
You have two possible solutions
1) String(Locale.preferredLanguages[0].prefix(2))
It returns phone lang properly.
If you want to get the type en-En
, you can use Locale.preferredLanguages[0]
2)
Select Project(MyApp)
->Project (not Target)
-> press + button into Localizations
, then add language which you want.
Dockerfile and Docker Compose are two different concepts in Dockerland. When we talk about Docker, the first things that come to mind are orchestration, OS level virtualization, images, containers, etc.. I will try to explain each as follows:
Image: An image is an immutable, shareable file that is stored in a Docker-trusted registry. A Docker image is built up from a series of read-only layers. Each layer represents an instruction that is being given in the image’s Dockerfile. An image holds all the required binaries to run.
Container: An instance of an image is called a container. A container is just an executable image binary that is to be run by the host OS. A running image is a container.
Dockerfile:
A Dockerfile is a text document that contains all of the commands / build instructions, a user could call on the command line to assemble an image. This will be saved as a Dockerfile
. (Note the lowercase 'f'.)
Docker-Compose:
Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services (containers). Then, with a single command, you create and start all the services from your configuration.
The Compose file would be saved as docker-compose.yml
.
Quote from The Swift Programming Language, which answers your question:
“Swift’s compiler performs four helpful safety-checks to make sure that two-phase initialization is completed without error:”
Safety check 1 “A designated initializer must ensure that all of the “properties introduced by its class are initialized before it delegates up to a superclass initializer.”

You can cast like this:
return this.createMarkerStyle(<MarkerSymbolInfo> symbolInfo);
Or like this if you want to be compatible with tsx mode:
return this.createMarkerStyle(symbolInfo as MarkerSymbolInfo);
Just remember that this is a compile-time cast, and not a runtime cast.
I came across this PHP diff class by Chris Boulton based on Python difflib which could be a good solution:
I had the same problem - for me it was the SQL Server running out of memory. Freeing up some memory solved the issue
Actually, it is as simple as setting major
and minor
separately:
In [9]: plot([23, 456, 676, 89, 906, 34, 2345])
Out[9]: [<matplotlib.lines.Line2D at 0x6112f90>]
In [10]: yscale('log')
In [11]: grid(b=True, which='major', color='b', linestyle='-')
In [12]: grid(b=True, which='minor', color='r', linestyle='--')
The gotcha with minor grids is that you have to have minor tick marks turned on too. In the above code this is done by yscale('log')
, but it can also be done with plt.minorticks_on()
.
Keep() method marks the specified key in the dictionary for retention
You can use Keep() when prevent/hold the value depends on additional logic.
when you read TempData one’s and want to hold for another request then use keep method, so TempData can available for next request as above example.
In R the equivalent function is seq
and you can use it with the option by
:
seq(from = 5, to = 100, by = 5)
# [1] 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100
In addition to by
you can also have other options such as length.out
and along.with
.
length.out: If you want to get a total of 10 numbers between 0 and 1, for example:
seq(0, 1, length.out = 10)
# gives 10 equally spaced numbers from 0 to 1
along.with: It takes the length of the vector you supply as input and provides a vector from 1:length(input).
seq(along.with=c(10,20,30))
# [1] 1 2 3
Although, instead of using the along.with
option, it is recommended to use seq_along
in this case. From the documentation for ?seq
seq
is generic, and only the default method is described here. Note that it dispatches on the class of the first argument irrespective of argument names. This can have unintended consequences if it is called with just one argument intending this to be taken as along.with: it is much better to useseq_along
in that case.
seq_along: Instead of seq(along.with(.))
seq_along(c(10,20,30))
# [1] 1 2 3
Hope this helps.
If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:
class YourNonActivityClass{
// variable to hold context
private Context context;
//save the context recievied via constructor in a local variable
public YourNonActivityClass(Context context){
this.context=context;
}
}
You can create instance of this class from the activity as follows:
new YourNonActivityClass(this);
Using ping in C# is achieved by using the method Ping.Send(System.Net.IPAddress)
, which runs a ping request to the provided (valid) IP address or URL and gets a response which is called an Internet Control Message Protocol (ICMP) Packet. The packet contains a header of 20 bytes which contains the response data from the server which received the ping request. The .Net framework System.Net.NetworkInformation
namespace contains a class called PingReply
that has properties designed to translate the ICMP
response and deliver useful information about the pinged server such as:
The following is a simple example using WinForms
to demonstrate how ping works in c#. By providing a valid IP address in textBox1
and clicking button1
, we are creating an instance of the Ping
class, a local variable PingReply
, and a string to store the IP or URL address. We assign PingReply
to the ping Send
method, then we inspect if the request was successful by comparing the status of the reply to the property IPAddress.Success
status. Finally, we extract from PingReply
the information we need to display for the user, which is described above.
using System;
using System.Net.NetworkInformation;
using System.Windows.Forms;
namespace PingTest1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Ping p = new Ping();
PingReply r;
string s;
s = textBox1.Text;
r = p.Send(s);
if (r.Status == IPStatus.Success)
{
lblResult.Text = "Ping to " + s.ToString() + "[" + r.Address.ToString() + "]" + " Successful"
+ " Response delay = " + r.RoundtripTime.ToString() + " ms" + "\n";
}
}
private void textBox1_Validated(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(textBox1.Text) || textBox1.Text == "")
{
MessageBox.Show("Please use valid IP or web address!!");
}
}
}
}
The above addMethod by Lod Lawson is not completely correct. It's $.validator and not $.validate and the validator method name cb_selectone requires quotes. Here is a corrected version that I tested:
$.validator.addMethod('cb_selectone', function(value,element){
if(element.length>0){
for(var i=0;i<element.length;i++){
if($(element[i]).val('checked')) return true;
}
return false;
}
return false;
}, 'Please select at least one option');

If both columns can contain NULL
, but you still want to merge them to a single string, the easiest solution is to use CONCAT_WS():
SELECT FirstName AS First_Name
, LastName AS Last_Name
, CONCAT_WS('', ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone
FROM TABLE1
This way you won't have to check for NULL
-ness of each column separately.
Alternatively, if both columns are actually defined as NOT NULL
, CONCAT() will be quite enough:
SELECT FirstName AS First_Name
, LastName AS Last_Name
, CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone
FROM TABLE1
As for COALESCE
, it's a bit different beast: given the list of arguments, it returns the first that's not NULL
.
Java has a feature called "checked exceptions". That means that there are certain kinds of exceptions, namely those that subclass Exception but not RuntimeException, such that if a method may throw them, it must list them in its throws declaration, say: void readData() throws IOException. IOException is one of those.
Thus, when you are calling a method that lists IOException in its throws declaration, you must either list it in your own throws declaration or catch it.
The rationale for the presence of checked exceptions is that for some kinds of exceptions, you must not ignore the fact that they may happen, because their happening is quite a regular situation, not a program error. So, the compiler helps you not to forget about the possibility of such an exception being raised and requires you to handle it in some way.
However, not all checked exception classes in Java standard library fit under this rationale, but that's a totally different topic.
We can declare a two dimensional array and directly store elements at the time of its declaration as:
int marks[][]={{50,60,55,67,70},{62,65,70,70,81},{72,66,77,80,69}};
Here int represents integer type elements stored into the array and the array name is 'marks'. int is the datatype for all the elements represented inside the "{" and "}" braces because an array is a collection of elements having the same data type.
Coming back to our statement written above: each row of elements should be written inside the curly braces. The rows and the elements in each row should be separated by a commas.
Now observe the statement: you can get there are 3 rows and 5 columns, so the JVM creates 3 * 5 = 15 blocks of memory. These blocks can be individually referred ta as:
marks[0][0] marks[0][1] marks[0][2] marks[0][3] marks[0][4]
marks[1][0] marks[1][1] marks[1][2] marks[1][3] marks[1][4]
marks[2][0] marks[2][1] marks[2][2] marks[2][3] marks[2][4]
NOTE:
If you want to store n elements then the array index starts from zero and ends at n-1.
Another way of creating a two dimensional array is by declaring the array first and then allotting memory for it by using new operator.
int marks[][]; // declare marks array
marks = new int[3][5]; // allocate memory for storing 15 elements
By combining the above two we can write:
int marks[][] = new int[3][5];
I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.
Bootstrap requires a specific file structure to work. I see from your code you have this:
<link href="bootstrap.css" rel="stylesheet" media="screen">
Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.
But first, let me recommend you setup your folder structure like so:
/css <-- Bootstrap.css here
/fonts <-- Bootstrap fonts here
/img
/js <-- Bootstrap JavaScript here
index.html
If you notice, this is also how Bootstrap structures its files in its download ZIP.
You then include your Bootstrap file like so:
<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">
Depending on your server structure or what you're going for.
The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).
The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.
So, why do this?
Bootstrap.css has this specific line for Glyphfonts:
@font-face {
font-family: 'Glyphicons Halflings';
src: url('../fonts/glyphicons-halflings-regular.eot');
src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}
What you can see is that that Glyphfonts are loaded by going up one directory ../
and then looking for a folder called /fonts
and THEN loading the font file.
The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:
/fonts
Bootstrap.css
index.html
The CSS file is going one level deeper than looking for a /fonts
folder.
So, let's say the actual location of these files are:
C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html
The CSS file would technically be looking for a folder at:
C:\fonts
but your folder is actually in:
C:\www\fonts
So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.
When you get that fixed, your HTML should simply be:
<span class="glyphicon glyphicon-comment"></span>
Note, you need both classes. The first class glyphicon
sets up the basic styles while glyphicon-comment
sets the specific image.
In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.
The second BEGIN's SQL statement doesn't have INTO clause and that caused the error.

// String.class here is the parameter type, that might not be the case with you
Method method = clazz.getMethod("methodName", String.class);
Object o = method.invoke(null, "whatever");
In case the method is private use getDeclaredMethod()
instead of getMethod()
. And call setAccessible(true)
on the method object.
I encountered the same thing lately. it was just due to spaces when copying a script from a document to sql developer. I had to remove the spaces and the script ran.
private String getMyPhoneNumber(){
TelephonyManager mTelephonyMgr;
mTelephonyMgr = (TelephonyManager)
getSystemService(Context.TELEPHONY_SERVICE);
return mTelephonyMgr.getLine1Number();
}
private String getMy10DigitPhoneNumber(){
String s = getMyPhoneNumber();
return s.substring(2);
}
List
in c#
has a Count
property. It can be used like so:
if(myList == null) // Checks if list is null
// Wasn't initialized
else if(myList.Count == 0) // Checks if the list is empty
myList.Add("new item");
else // List is valid and has something in it
// You could access the element in the list if you wanted
//This method involves directly integrating HTML Code in the res.write
//first time posting to stack ...pls be kind
const express = require('express');
const app = express();
const https = require('https');
app.get("/",function(res,res){
res.write("<img src="+image url / src +">");
res.send();
});
app.listen(3000, function(req, res) {
console.log("the server is onnnn");
});

You can compile with either Cygwin's g++
or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll
(and others) PATH to the system Windows PATH, before any cygwin style paths.
Thus add: ;C:\cygwin64\bin
to the end of your Windows system PATH
variable.
Also, to compile for use in CMD or PowerShell, you may need to use:
x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe
(This invokes the cross-compiler, if installed.)
Do you have multiple mongodb nodes in a replica set?
I found (I am using via Robomongo gui mongo shell, I guess same applies in other cases) that the correct remove syntax, i.e.
db.test_users.remove({"_id": ObjectId("4d512b45cc9374271b02ec4f")})
...does not work unless you are connected to the primary node of the replica set.
