The reason why the <sup> tag is affecting the spacing between two lines has to do with a number of factors. The factors are: line height, size of the superscript in relation to the regular font, the line height of the superscript and last but not least what is the bottom of the superscript aligning with...
If you set... the line height of regular text to be in a "tunnel band" (that's what I call it) of 135% then regular text (the 100%) gets white padded by 35% of more white. For a paragraph this looks like this:
p
{
line-height: 135%;
}
If you then do not white pad the superscript...(i.e. keep its line height to 0) the superscript only has the width of its own text... if you then ask the superscript to be a percentage of the regular font (for example 70%) and you align it with the middle of the regular text (text-middle), you can eliminate the problem and get a superscript that looks like a superscript. Here it is:
sup
{
font-size: 70%;
vertical-align: text-middle;
line-height: 0;
}
The best and easiest way to clear a JLIST is:
myJlist.setListData(new String[0]);
My solution to that problem is also somewhat of a mix of some solutions already stated here:
local_settings.py that has the content USING_LOCAL = True in dev and USING_LOCAL = False in prodsettings.py I do an import on that file to get the USING_LOCAL settingI then base all my environment-dependent settings on that one:
DEBUG = USING_LOCAL
if USING_LOCAL:
# dev database settings
else:
# prod database settings
I prefer this to having two separate settings.py files that I need to maintain as I can keep my settings structured in a single file easier than having them spread across several files. Like this, when I update a setting I don't forget to do it for both environments.
Of course that every method has its disadvantages and this one is no exception. The problem here is that I can't overwrite the local_settings.py file whenever I push my changes into production, meaning I can't just copy all files blindly, but that's something I can live with.
If you don't want to build Tensorflow yourself and your operating system is Debian or Ubuntu, you can download prebuilt packages with the Tensorflow C/C++ libraries. This distribution can be used for C/C++ inference with CPU, GPU support is not included:
https://github.com/kecsap/tensorflow_cpp_packaging/releases
There are instructions written how to freeze a checkpoint in Tensorflow (TFLearn) and load this model for inference with the C/C++ API:
https://github.com/kecsap/tensorflow_cpp_packaging/blob/master/README.md
Beware: I am the developer of this Github project.
A sort of block comment uses an if statement:
if(FALSE) {
all your code
}
It works, but I almost always use the block comment options of my editors (RStudio, Kate, Kwrite).
All the symptoms you describe suggest that you never tell MySQL what time zone to use so it defaults to system's zone. Think about it: if all it has is '2011-03-13 02:49:10', how can it guess that it's a local Tanzanian date?
As far as I know, MySQL doesn't provide any syntax to specify time zone information in dates. You have to change it a per-connection basis; something like:
SET time_zone = 'EAT';
If this doesn't work (to use named zones you need that the server has been configured to do so and it's often not the case) you can use UTC offsets because Tanzania does not observe daylight saving time at the time of writing but of course it isn't the best option:
SET time_zone = '+03:00';
I'd actually suggest using a solid open-source library as an http client. If you take a look at http client by ASF you'll find life a lot easier. It is an easy-to-use,scalable and robust client for http.
It's highly probable that you want to have a text next to the checkbox. In that case, you can put the checkbox inside a label like I do below:
<label style="width: 150px;"><input type="checkbox" name="damageTypeItems" value="72" aria-required="true" class="error"> All Over</label>
<label style="width: 150px;"><input type="checkbox" name="damageTypeItems" value="73" aria-required="true" class="error"> All Over X2</label>
The problem is that when the error message is displayed, it's going to be inserted after the checkbox but before the text, making it unreadable. In order to fix that, I changed the error placement function:
if (element.is(":checkbox")) {
error.insertAfter(element.parent().parent());
}
else {
error.insertAfter(element);
}
It depends on your layout but what I did is to have a special error placement for checkbox controls. I get the parent of the checkbox, which is a label, and then I get the parent of it, which is a div in my case. This way, the error is placed below the list of checkbox controls.
"Allocation Failure" is cause of GC to kick is not correct. It is an outcome of GC operation.
GC kicks in when there is no space to allocate( depending on region minor or major GC is performed). Once GC is performed if space is freed good enough, but if there is not enough size it fails. Allocation Failure is one such failure. Below document have good explanation https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc.html
Test for ':' first, then take test string up to ':' or end, depending on if it was found
Dim strResult As String
' Position of :
intPos = InStr(1, strTest, ":")
If intPos > 0 Then
' : found, so take up to :
strResult = Left(strTest, intPos - 1)
Else
' : not found, so take whole string
strResult = strTest
End If
There are 2 way to create your TOC (summary) in your markdown document.
# My Table of content
- [Section 1](#id-section1)
- [Section 2](#id-section2)
<div id='id-section1'/>
## Section 1
<div id='id-section2'/>
## Section 2
You can use for example a script that generate summary for you, take a look to my project on github - summarizeMD -
I've tried also other script/npm module (for example doctoc) but no one reproduce a TOC with working anchors.
public class Test {
int[] array = { 1, 99, 10000, 84849, 111, 212, 314, 21, 442, 455, 244, 554,
22, 22, 211 };
public void Printrange() {
for (int i = 0; i < array.length; i++) { // <-- use array.length
if (array[i] > 100 && array[i] < 500) {
System.out.println("numbers with in range :" + array[i]);
}
}
}
}
Use the latest maven in your classpath.. It will remove the duplicate artifacts and keep the latest maven artifact..
I had the same issue using the request module to proxy POST request from somewhere else and it was because I left the host property in the header (I was copying the header from the original request).
You're looking for the /Y switch.
I actually hit on this problem a week ago. The issue had to do with not using an updated Eclipse version of the Android SDK plugin with the latest version of the SDK. It was a fun problem overall, but it disappeared as soon as I updated it.
I had even updated the AVD images and no luck. Apparently the old plugin cannot see the new image layout or something. This is for version 22.3 of the SDK.
There should be a way to solve this pretty easily with external config sections and an extra deployment step that drops a deployment specific external .config file into a known location. We typically use this solution to handle the different server configurations for our different deployment environments (Staging, QA, production, etc) with our "dev box" being the default if no special copy occurs.
This error tells you everything:
undefined reference toHash::insert(int, char)
You're not linking with the implementations of functions defined in Hash.h. Don't you have a Hash.cpp to also compile and link?
Easy peasy. Your data frame will look like this:
df <- data.frame(sex=c('M','F','M'),
occupation=c('Student','Analyst','Analyst'))
You can then do the equivalent of a COUNTIF by first specifying the IF part, like so:
df$sex == 'M'
This will give you a boolean vector, i.e. a vector of TRUE and FALSE. What you want is to count the observations for which the condition is TRUE. Since in R TRUE and FALSE double as 1 and 0 you can simply sum() over the boolean vector. The equivalent of COUNTIF(sex='M') is therefore
sum(df$sex == 'M')
Should there be rows in which the sex is not specified the above will give back NA. In that case, if you just want to ignore the missing observations use
sum(df$sex == 'M', na.rm=TRUE)
Use like this in Swift,
let placeHolderText = textField.placeholder ?? ""
let str = NSAttributedString(string:placeHolderText!, attributes: [NSAttributedString.Key.foregroundColor :UIColor.lightGray])
textField.attributedPlaceholder = str
In Objective C
NSString *placeHolder = [textField.placeholder length]>0 ? textField.placeholder: @"";
NSAttributedString *str = [[NSAttributedString alloc] initWithString:placeHolder attributes:@{ NSForegroundColorAttributeName : [UIColor lightGrayColor] }];
textField.attributedPlaceholder = str;
I know this has already been answered, but I just spent more time than I care to admit coming up with single-line SQL statements to accomplish this, so I'll share them here in case anyone else needs to do the same:
-- Encode the string "TestData" in Base64 to get "VGVzdERhdGE="
SELECT
CAST(N'' AS XML).value(
'xs:base64Binary(xs:hexBinary(sql:column("bin")))'
, 'VARCHAR(MAX)'
) Base64Encoding
FROM (
SELECT CAST('TestData' AS VARBINARY(MAX)) AS bin
) AS bin_sql_server_temp;
-- Decode the Base64-encoded string "VGVzdERhdGE=" to get back "TestData"
SELECT
CAST(
CAST(N'' AS XML).value(
'xs:base64Binary("VGVzdERhdGE=")'
, 'VARBINARY(MAX)'
)
AS VARCHAR(MAX)
) ASCIIEncoding
;
I had to use a subquery-generated table in the first (encoding) query because I couldn't find any way to convert the original value ("TestData") to its hex string representation ("5465737444617461") to include as the argument to xs:hexBinary() in the XQuery statement.
I hope this helps someone!
All of the information you are looking for can be found here and here (thanks Reed Copsey):
From the first link:
Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.
...
The access level for class members and struct members, including nested classes and structs, is private by default.
...
interfaces default to internal access.
...
Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested.
From the second link:
Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.
And for nested types:
Members of Default member accessibility ---------- ---------------------------- enum public class private interface public struct private
A float isn't have 0 or 0.00 : those are different string representations of the internal (IEEE754) binary format but the float is the same.
If you want to express your float as "0.00", you need to format it in a string, using number_format :
$numberAsString = number_format($numberAsFloat, 2);
I think the new preferred way might be to use IDataErrorInfo

Did you try using SELECT PostGIS_version();
Maybe I've late a bit, but you really should try to use json library from play framework. You could look at documentation. In current 2.1.1 release you could not separately use it without whole play 2, so dependency will looks like this:
val typesaferepo = "TypeSafe Repo" at "http://repo.typesafe.com/typesafe/releases"
val play2 = "play" %% "play" % "2.1.1"
It will bring you whole play framework with all stuff on board.
But as I know guys from Typesafe have a plan to separate it in 2.2 release. So, there is standalone play-json from 2.2-snapshot.
f.write(plaintext)
f.write("\n".encode("utf-8"))
If you are using graphLab, you can use this function. It is really powerfull
products['word_count'] = graphlab.text_analytics.count_words(your_text)
You can use list comprehension:
res_list = [i[0] for i in rows]
This should make the trick
You start a thread which runs the static method SumData. However, SumData calls SetTextboxText which isn't static. Thus you need an instance of your form to call SetTextboxText.
Another way to look at this. Check out the details of the exception:
In [49]: try:
...: open('file.DNE.txt')
...: except Exception as e:
...: print(dir(e))
...:
['__cause__', '__class__', '__context__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setstate__', '__sizeof__', '__str__', '__subclasshook__', '__suppress_context__', '__traceback__', 'args', 'characters_written', 'errno', 'filename', 'filename2', 'strerror', 'with_traceback']
There are lots of "things" to access using the 'as e' syntax.
This code was solely meant to show the details of this instance.
The following lines are used to control the listen-port of a server, both are necessary:
<listen-port>7002</listen-port>
<listen-port-enabled>true</listen-port-enabled>
I found an easy way to do this -
Just enter a command like this -
>mvn -Dtest=TestClassName#methodname -Dmaven.surefire.debug test
It will start listening to 5005 port. Now just create a remote debugging in Eclipse through Debug Configurations for localhost(any host) and port 5005.

Quote from the documentation:
Any Objective-C framework (or C library) that’s accessible as a module can be imported directly into Swift. This includes all of the Objective-C system frameworks—such as Foundation, UIKit, and SpriteKit—as well as common C libraries supplied with the system. For example, to import Foundation, simply add this import statement to the top of the Swift file you’re working in:
import FoundationThis import makes all of the Foundation APIs—including NSDate, NSURL, NSMutableData, and all of their methods, properties, and categories—directly available in Swift.
Think of the phrase in the square brackets as a WHERE clause in SQL.
So this query says, "select the "href" attribute (@) of an "a" tag that appears anywhere (//), but only where (the bracketed phrase) the textual contents of the "a" tag is equal to 'programming questions site'".
Sometimes it is the simple things. In my case, I had an invalid url. I had left out a colon before the at sign (@). I had "jdbc:oracle:thin@//localhost" instead of "jdbc:oracle:thin:@//localhost" Hope this helps someone else with this issue.
You cannot use primitive types in HashMap. int, or double don't work. You have to use its enclosing type. for an example
Map<String,Integer> m = new HashMap<String,Integer>();
Now both are objects, so this will work.
With Homebrew and jenv:
Assumption: Mac machine and you already have installed homebrew.
Install cask:
$ brew tap caskroom/cask
$ brew tap caskroom/versions
To install latest java:
$ brew cask install java
To install java 8:
$ brew cask install java8
To install java 9:
$ brew cask install java9
If you want to install/manage multiple version then you can use 'jenv':
Install and configure jenv:
$ brew install jenv
$ echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(jenv init -)"' >> ~/.bash_profile
$ source ~/.bash_profile
Add the installed java to jenv:
$ jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
$ jenv add /Library/Java/JavaVirtualMachines/jdk1.11.0_2.jdk/Contents/Home
To see all the installed java:
$ jenv versions
Above command will give the list of installed java:
* system (set by /Users/lyncean/.jenv/version)
1.8
1.8.0.202-ea
oracle64-1.8.0.202-ea
Configure the java version which you want to use:
$ jenv global oracle64-1.6.0.39
Per Mozilla's Map documentation, you can initialize as follows:
private _gridOptions:Map<string, Array<string>> =
new Map([
["1", ["test"]],
["2", ["test2"]]
]);
Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.
I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.
If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.
This should do it:
private enum Alignment { LEFT, RIGHT };
String drawCellValue (int maxCellLength, String cellValue, Alignment align){
if (align == Alignment.LEFT)
{
//Process it...
}
}
My 'Map' implementation, derived from Christoph's example:
Example usage:
var map = new Map(); // Creates an "in-memory" map
var map = new Map("storageId"); // Creates a map that is loaded/persisted using html5 storage
function Map(storageId) {
this.current = undefined;
this.size = 0;

this.next = Map.illegal;

value.toString());
};
Map.prototype.hash.current = 0;
// --- Mapping functions
Map.prototype.get = function(key) {
var item = this[this.hash(key)];
if (item === undefined) {
if (this.storageId) {
try {
var itemStr = localStorage.getItem(this.storageId + key);
if (itemStr && itemStr !== 'undefined') {

Finally I found solution in Spring Docs:
To completely disable the use of file extensions, you must set both of the following:
useSuffixPatternMatching(false), see PathMatchConfigurer favorPathExtension(false), see ContentNegotiationConfigurer
Adding this to my WebMvcConfigurerAdapter implementation solved the problem:
@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
configurer.favorPathExtension(false);
}
@Override
public void configurePathMatch(PathMatchConfigurer matcher) {
matcher.setUseSuffixPatternMatch(false);
}
The referenced primary key is described in the columns r_owner and r_constraint_name of the table ALL_CONSTRAINTS. This will give you the info you want:
SELECT a.table_name, a.column_name, a.constraint_name, c.owner,
-- referenced pk
c.r_owner, c_pk.table_name r_table_name, c_pk.constraint_name r_pk
FROM all_cons_columns a
JOIN all_constraints c ON a.owner = c.owner
AND a.constraint_name = c.constraint_name
JOIN all_constraints c_pk ON c.r_owner = c_pk.owner
AND c.r_constraint_name = c_pk.constraint_name
WHERE c.constraint_type = 'R'
AND a.table_name = :TableName
You can also make it a reusable method by expending JavaScript:
Array.prototype.findIndexBy = function(key, value) {
return this.findIndex(item => item[key] === value)
}
const peoples = [{name: 'john'}]
const cats = [{id: 1, name: 'kitty'}]
peoples.findIndexBy('name', 'john')
cats.findIndexBy('id', 1)
For completeness sake the reverse function:
function a2hex(str) {
var arr = [];
for (var i = 0, l = str.length; i < l; i ++) {
var hex = Number(str.charCodeAt(i)).toString(16);
arr.push(hex);
}
return arr.join('');
}
a2hex('2460'); //returns 32343630
As described elsewhere, perhaps the best solution is to use the logging module directly:
import logging
logging.basicConfig(level=logging.DEBUG, filename='mylog.log')
logging.info('this should to write to the log file')
However, there are some (rare) occasions where you really want to redirect stdout. I had this situation when I was extending django's runserver command which uses print: I didn't want to hack the django source but needed the print statements to go to a file.
This is a way of redirecting stdout and stderr away from the shell using the logging module:
import logging, sys
class LogFile(object):
"""File-like object to log text using the `logging` module."""
def __init__(self, name=None):
self.logger = logging.getLogger(name)
def write(self, msg, level=logging.INFO):
self.logger.log(level, msg)
def flush(self):
for handler in self.logger.handlers:
handler.flush()
logging.basicConfig(level=logging.DEBUG, filename='mylog.log')
# Redirect stdout and stderr
sys.stdout = LogFile('stdout')
sys.stderr = LogFile('stderr')
print 'this should to write to the log file'
You should only use this LogFile implementation if you really cannot use the logging module directly.
You should assign setTimeout to a variable and use clearTimeout to clear it on keypress.
var timer = '';
$('input#username').keypress(function() {
clearTimeout(timer);
timer = setTimeout(function() {
//Your code here
}, 3000); //Waits for 3 seconds after last keypress to execute the above lines of code
});
Hope this helps.
In my case I was using a third party library (i.e. vendor) and the library comes with a sample app which I already had install on my device. So that sample app was now conflicting each time I try to install my own app implementing the library. So I just uninstalled the vendor's sample app and it works afterwards.
The trick with relying upon IIS is that IIS bindings can be different from your public URLs (WCF I'm looking at you), especially with multi-homed production machines. I tend to vector toward using configuration to explicitly define the "base" url for external purposes as that tends to be a bit more successful than extracting it from the Request object.
tabindex HTML attribute indicates if its element can be focused, and if/where it participates in sequential keyboard navigation (usually with the Tab key). Read MDN Web Docs for full reference.
$( "#division" ).keydown(function(evt) {
evt = evt || window.event;
console.log("keydown: " + evt.keyCode);
});#division {
width: 90px;
height: 30px;
background: lightgrey;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="division" tabindex="0"></div>var el = document.getElementById("division");
el.onkeydown = function(evt) {
evt = evt || window.event;
console.log("keydown: " + evt.keyCode);
};#division {
width: 90px;
height: 30px;
background: lightgrey;
}<div id="division" tabindex="0"></div>There is actually a pure javascript way to accomplish this without using setTimeout or requestAnimationFrame or jQuery.
In short, find the element in the scrollView that you want to scroll to, and use scrollIntoView.
el.scrollIntoView({behavior:"smooth"});
Here is a plunkr.
Very very easy: [1,2,3]
A list is like a column.
1
2
3
If you want a list like a row, double corchete:
[[1, 2, 3]] ---> 1, 2, 3
and
[[1, 2, 3], [4, 5, 6]] ---> 1, 2, 3
4, 5, 6
Finally:
np.savetxt("file", [['r1c1', 'r1c2'], ['r2c1', 'r2c2']], delimiter=';', fmt='%s')
Note, the comma between square brackets, inner list are elements of the outer list
There are 2 major differences.
Technical, there are 3 major differences:
First and foremost, Community doesn't have TFS support.
You'll just have to use git (arguable whether this constitutes a disadvantage or whether this actually is a good thing).
Note: This is what MS wrote. Actually, you can check-in&out with TFS as normal, if you have a TFS server in the network. You just cannot use Visual Studio as TFS SERVER.
Second, VS Community is severely limited in its testing capability.
Only unit tests. No Performance tests, no load tests, no performance profiling.
Third, VS Community's ability to create Virtual Environments has been severely cut.
On the other hand, syntax highlighting, IntelliSense, Step-Through debugging, GoTo-Definition, Git-Integration and Build/Publish are really all the features I need, and I guess that applies to a lot of developers.
For all other things, there are tools that do the same job faster, better and cheaper.
If you, like me, anyway use git, do unit testing with NUnit, and use Java-Tools to do Load-Testing on Linux plus TeamCity for CI, VS Community is more than sufficient, technically speaking.
Licensing:
A) If you're an individual developer (no enterprise, no organization), no difference (AFAIK), you can use CommunityEdition like you'd use the paid edition (as long as you don't do subcontracting)
B) You can use CommunityEdition freely for OpenSource (OSI) projects
C) If you're an educational insitution, you can use CommunityEdition freely (for education/classroom use)
D) If you're an enterprise with 250 PCs or users or more than one million US dollars in revenue (including subsidiaries), you are NOT ALLOWED to use CommunityEdition.
E) If you're not an enterprise as defined above, and don't do OSI or education, but are an "enterprise"/organization, with 5 or less concurrent (VS) developers, you can use VS Community freely (but only if you're the owner of the software and sell it, not if you're a subcontractor creating software for a larger enterprise, software which in the end the enterprise will own), otherwise you need a paid edition.
The above does not consitute legal advise.

TRUNCATE TABLE table;
is the SQL command. In PHP, you'd use:
mysql_query('TRUNCATE TABLE table;');
You can get the version of the jquery by simply printing object.jquery, the object can be any object created by you using $.
For example: if you have created a <div> element as following
var divObj = $("div");
then by printing divObj.jquery will show you the version like 1.7.1
Basically divObj inherits all the property of $() or jQuery() i.e if you try to print jQuery.fn.jquery will also print the same version like 1.7.1
You can use this:
NumberFormat formatter = new DecimalFormat("00");
String s = formatter.format(1); // ----> 01
You could handle the exception directly so it would not crash your program (catching the AggregateException). You could also look at the Inner Exception, this will give you a more detailed explanation of what went wrong:
try {
// your code
} catch (AggregateException e) {
}
cardeal's answer was really helpful. Took it a little further and figured it may help others some where down the line. Here is the fiddle:

And the code:

If you need the difference in seconds (i.e.: you're comparing dates with timestamps, and not whole days), you can simply convert two date or timestamp strings in the format 'YYYY-MM-DD HH:MM:SS' (or specify your string date format explicitly) using unix_timestamp(), and then subtract them from each other to get the difference in seconds. (And can then divide by 60.0 to get minutes, or by 3600.0 to get hours, etc.)
Example:
UNIX_TIMESTAMP('2017-12-05 10:01:30') - UNIX_TIMESTAMP('2017-12-05 10:00:00') AS time_diff -- This will return 90 (seconds). Unix_timestamp converts string dates into BIGINTs.
More on what you can do with unix_timestamp() here, including how to convert strings with different date formatting: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-DateFunctions
I found the best answer for my purposes was to use:
.topics tr {
overflow: hidden;
height: 14px;
white-space: nowrap;
}
The white-space: nowrap is important as it prevents your row's cells from breaking across multiple lines.
I personally like to add text-overflow: ellipsis to my th and td elements to make the overflowing text look nicer by adding the trailing fullstops, for example Too long gets dots...
Gradle put the fun back into building/assembling software. I used ant to build software my entire career and I have always considered the actual "buildit" part of the dev work being a necessary evil. A few months back our company grew tired of not using a binary repo (aka checking in jars into the vcs) and I was given the task to investigate this. Started with ivy since it could be bolted on top of ant, didn't have much luck getting my built artifacts published like I wanted. I went for maven and hacked away with xml, worked splendid for some simple helper libs but I ran into serious problems trying to bundle applications ready for deploy. Hassled quite a while googling plugins and reading forums and wound up downloading trillions of support jars for various plugins which I had a hard time using. Finally I went for gradle (getting quite bitter at this point, and annoyed that "It shouldn't be THIS hard!")
But from day one my mood started to improve. I was getting somewhere. Took me like two hours to migrate my first ant module and the build file was basically nothing. Easily fitted one screen. The big "wow" was: build scripts in xml, how stupid is that? the fact that declaring one dependency takes ONE row is very appealing to me -> you can easily see all dependencies for a certain project on one page. From then on I been on a constant roll, for every problem I faced so far there is a simple and elegant solution. I think these are the reasons:
Now I spend my days trying to think up new features to add to our build process. How sick is that?
a = dict(one=1, two=2, three=3)
Providing keyword arguments as in this example only works for keys that are valid Python identifiers. Otherwise, any valid keys can be used.
It is privacy concern. It is recommended to disallow users to backup an app if it contains sensitive data. Having access to backup files (i.e. when android:allowBackup="true"), it is possible to modify/read the content of an app even on a non-rooted device.
Solution - use android:allowBackup="false" in the manifest file.
You can read this post to have more information: Hacking Android Apps Using Backup Techniques
First, choosing a data structure(xml,json,yaml) usually includes only a readability/size problem. For example
Json is very compact, but no human being can read it easily, very hard do debug,
Xml is very large, but everyone can easily read/debug it,
Yaml is in between Xml and json.
But if you want to work with Javascript heavily and/or your software makes a lot of data transfer between browser-server, you should use Json, because it is pure javascript and very compact. But don't try to write it in a string, use libraries to generate the code you needed from an object.
Hope this helps.
IMO the nicest way is to use the next() function:
router.get('/', function(req, res, next) {
var err = new Error('Not found');
err.status = 404;
return next(err);
}
Then the error is handled by your error handler and you can style the error nicely using HTML.
I found that when I was reading strings in from a .plist file, occurrences of "\n" were parsed as "\\n". The solution for me was to replace occurrences of "\\n" with "\n". For example, given an instance of NSString named myString read in from my .plist file, I had to call...
myString = [myString stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"];
... before assigning it to my UILabel instance...
myLabel.text = myString;
SQL Supports following types of affinities:
If the declared type for a column contains any of these "REAL", "FLOAT", or "DOUBLE" then the column has 'REAL' affinity.
You really should fix whatever's causing the warning, but you can control visibility of errors with error_reporting(). To skip warning messages, you could use something like:
error_reporting(E_ERROR | E_PARSE);
The pack method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame size explicitly by calling setSize or setBounds (which also sets the frame location). In general, using pack is preferable to calling setSize, since pack leaves the frame layout manager in charge of the frame size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.
From Java tutorial
You should also refer to Javadocs any time you need additional information on any Java API
Walrus operator (assignment expressions added to python 3.8) and while-loop-else-clause can do it more pythonic:
myScore = 0
while ans := input("Roll...").lower() == "r":
# ... do something
else:
print("Now I'll see if I can break your score...")
UITableView's selectRowAtIndexPath:animated:scrollPosition: should do the trick.
Just pass UITableViewScrollPositionNone for scrollPosition and the user won't see any movement.
You should also be able to manually run the action:
[theTableView.delegate tableView:theTableView didSelectRowAtIndexPath:indexPath]
after you selectRowAtIndexPath:animated:scrollPosition: so the highlight happens as well as any associated logic.
I vote for Karthik T's answer. you don't need to open a terminal to run commands.
For example,
// file: RunShellCommandFromJava.java
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class RunShellCommandFromJava {
public static void main(String[] args) {
String command = "ping -c 3 www.google.com";
Process proc = Runtime.getRuntime().exec(command);
// Read the output
BufferedReader reader =
new BufferedReader(new InputStreamReader(proc.getInputStream()));
String line = "";
while((line = reader.readLine()) != null) {
System.out.print(line + "\n");
}
proc.waitFor();
}
}
The output:
$ javac RunShellCommandFromJava.java
$ java RunShellCommandFromJava

Although the DATEADD is probably the most transparrent way of doing this, it is worth noting
that simply getdate()-30 will also suffice.
Also, are you looking for 30 days from now, i.e. including hours, minutes, seconds, etc? Or 30 days from midnight today (e.g. 12/06/2010 00:00:00.000). In which case, you might consider:
SELECT *
FROM Results
WHERE convert(varchar(8), [Date], 112) >= convert(varchar(8), getdate(), 112)
.tbl {
table-layout:fixed;
border-collapse: collapse;
background: #fff;
}
.tbl td {
text-overflow:ellipsis;
overflow:hidden;
white-space:nowrap;
}

I've found another reason this fails... case sensitive table names.
For this table definition
CREATE TABLE user (
userId int PRIMARY KEY AUTO_INCREMENT,
username varchar(30) NOT NULL
) ENGINE=InnoDB;
This table definition works
CREATE TABLE product (
id int PRIMARY KEY AUTO_INCREMENT,
userId int,
FOREIGN KEY fkProductUser1(userId) REFERENCES **u**ser(userId)
) ENGINE=InnoDB;
whereas this one fails
CREATE TABLE product (
id int PRIMARY KEY AUTO_INCREMENT,
userId int,
FOREIGN KEY fkProductUser1(userId) REFERENCES User(userId)
) ENGINE=InnoDB;
The fact that it worked on Windows and failed on Unix took me a couple of hours to figure out. Hope that helps someone else.
The main answer worked for me but made the app extremely unresponsive in IE, so I used a timer as suggested. Code looks something like this ($(#contentColumn) is the div that the JQGrid sits in):
function resizeGrids() {
var reportObjectsGrid = $("#ReportObjectsGrid");
reportObjectsGrid.setGridWidth($("#contentColumn").width());
};
var resizeTimer;
$(window).bind('resize', function () {
clearTimeout(resizeTimer);
resizeTimer = setTimeout(resizeGrids, 60);
});
For no particular reason, arrays cannot be assigned to one another. Use std::copy instead:
#include <algorithm>
// ...
int a[8] = {2, 3, 5, 7, 11, 13, 17, 19};
int b[8];
std::copy(a + 0, a + 8, b);
This is more flexible than what true array assignment could provide because it is possible to copy slices of larger arrays into smaller arrays.
std::copy is usually specialized for primitive types to give maximum performance. It is unlikely that std::memcpy performs better. If in doubt, measure.
Although you cannot assign arrays directly, you can assign structs and classes which contain array members. That is because array members are copied memberwise by the assignment operator which is provided as a default by the compiler. If you define the assignment operator manually for your own struct or class types, you must fall back to manual copying for the array members.
Arrays cannot be passed by value. You can either pass them by pointer or by reference.
Since arrays themselves cannot be passed by value, usually a pointer to their first element is passed by value instead. This is often called "pass by pointer". Since the size of the array is not retrievable via that pointer, you have to pass a second parameter indicating the size of the array (the classic C solution) or a second pointer pointing after the last element of the array (the C++ iterator solution):
#include <numeric>
#include <cstddef>
int sum(const int* p, std::size_t n)
{
return std::accumulate(p, p + n, 0);
}
int sum(const int* p, const int* q)
{
return std::accumulate(p, q, 0);
}
As a syntactic alternative, you can also declare parameters as T p[], and it means the exact same thing as T* p in the context of parameter lists only:
int sum(const int p[], std::size_t n)
{
return std::accumulate(p, p + n, 0);
}
You can think of the compiler as rewriting T p[] to T *p in the context of parameter lists only. This special rule is partly responsible for the whole confusion about arrays and pointers. In every other context, declaring something as an array or as a pointer makes a huge difference.
Unfortunately, you can also provide a size in an array parameter which is silently ignored by the compiler. That is, the following three signatures are exactly equivalent, as indicated by the compiler errors:
int sum(const int* p, std::size_t n)
// error: redefinition of 'int sum(const int*, size_t)'
int sum(const int p[], std::size_t n)
// error: redefinition of 'int sum(const int*, size_t)'
int sum(const int p[8], std::size_t n) // the 8 has no meaning here
Arrays can also be passed by reference:
int sum(const int (&a)[8])
{
return std::accumulate(a + 0, a + 8, 0);
}
In this case, the array size is significant. Since writing a function that only accepts arrays of exactly 8 elements is of little use, programmers usually write such functions as templates:
template <std::size_t n>
int sum(const int (&a)[n])
{
return std::accumulate(a + 0, a + n, 0);
}
Note that you can only call such a function template with an actual array of integers, not with a pointer to an integer. The size of the array is automatically inferred, and for every size n, a different function is instantiated from the template. You can also write quite useful function templates that abstract from both the element type and from the size.
Try this:
img {
height: auto;
width: 100%;
-webkit-border-radius: 50%;
-moz-border-radius: 50%;
-ms-border-radius: 50%;
-o-border-radius: 50%;
border-radius: 50%;
}
OR:
.rounded {
height: 100px;
width: 100px;
-webkit-border-radius: 50%;
-moz-border-radius: 50%;
-ms-border-radius: 50%;
-o-border-radius: 50%;
border-radius: 50%;
background:url("http://www.electricvelocity.com.au/Upload/Blogs/smart-e-bike-side_2.jpg") center no-repeat;
background-size:cover;
}
Or you could use the CURRENT_DATE alternative, with the same result:
SELECT * FROM yourtable WHERE created >= CURRENT_DATE
=COUNTIFS(H5:H21000,">=100", H5:H21000,"<999")
You must define the class before creating an instance of the class. Move the invocation of Something to the end of the script.
You can try to put the cart before the horse and invoke procedures before they are defined, but it will be an ugly hack and you will have to roll your own as defined here:
jQuery("#input").live('change', function() {
// since we check more than once against the value, place it in a var.
var inputvalue = $("#input").attr("value");
// if it's value **IS NOT** ""
if(inputvalue !== "") {
jQuery(this).css('outline', 'solid 1px red');
}
// else if it's value **IS** ""
else if(inputvalue === "") {
alert('empty');
}
});
__repr__ is used by the standalone Python interpreter to display a class in printable format. Example:
~> python3.5
Python 3.5.1 (v3.5.1:37a07cee5969, Dec 5 2015, 21:12:44)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> class StackOverflowDemo:
... def __init__(self):
... pass
... def __repr__(self):
... return '<StackOverflow demo object __repr__>'
...
>>> demo = StackOverflowDemo()
>>> demo
<StackOverflow demo object __repr__>
In cases where a __str__ method is not defined in the class, it will call the __repr__ function in an attempt to create a printable representation.
>>> str(demo)
'<StackOverflow demo object __repr__>'
Additionally, print()ing the class will call __str__ by default.
Documentation, if you please
Doing type('') is effectively equivalent to str and types.StringType
so type('') == str == types.StringType will evaluate to "True"
Note that Unicode strings which only contain ASCII will fail if checking types in this way, so you may want to do something like assert type(s) in (str, unicode) or assert isinstance(obj, basestring), the latter of which was suggested in the comments by 007Brendan and is probably preferred.
isinstance() is useful if you want to ask whether an object is an instance of a class, e.g:
class MyClass: pass
print isinstance(MyClass(), MyClass) # -> True
print isinstance(MyClass, MyClass()) # -> TypeError exception
But for basic types, e.g. str, unicode, int, float, long etc asking type(var) == TYPE will work OK.

Just want to throw something in to help people still having this problem. (for me at least) the css is showing that it puts default classes of level1, level2, and level3 on each piece of the menu(level 1 being the menu, level2 being the first dropdown, level3 being the third popout). Setting the padding in css
.level2
{
padding: 2px 2px 2px 2px;
}
does work for adding the padding to each li in the first dropdown.
You can simply use replace() function,
with where clause-
update tabelName set columnName=REPLACE(columnName,'from','to') where condition;
without where clause-
update tabelName set columnName=REPLACE(columnName,'from','to');
Note: The above query if for update records directly in table, if you want on select query and the data should not be affected in table then can use the following query-
select REPLACE(columnName,'from','to') as updateRecord;
Try import .lib.BoxTime. For more information read about relative import in PEP 328.
It can also be done this way:
figure(xx);
set(gcf, 'name', 'Name goes here')
gcf gets the current figure handle.

Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable
jQuery(function(){
//here it is a closure variable
var a_href;
$('sth a').on('click', function(e){
a_href = $(this).attr('href');
console.log(a_href);
//output is "home"
e.preventDefault();
}
})
To make the variable global, one solution is to declare the variable in global scope
var a_href;
jQuery(function(){
$('sth a').on('click', function(e){
a_href = $(this).attr('href');
console.log(a_href);
//output is "home"
e.preventDefault();
}
})
another is to set the variable as a property of the window object
window.a_href = $(this).attr('href')
Why console printing undefined
You are getting the output as undefined because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a element is clicked till that time the variable will have the value undefined. If you are not declaring the variable it will throw a ReferenceError
Wikipedia has the answer, along with a number of other sources.
A segfault basically means you did something bad with pointers. This is probably a segfault:
char *c = NULL;
...
*c; // dereferencing a NULL pointer
Or this:
char *c = "Hello";
...
c[10] = 'z'; // out of bounds, or in this case, writing into read-only memory
Or maybe this:
char *c = new char[10];
...
delete [] c;
...
c[2] = 'z'; // accessing freed memory
Same basic principle in each case - you're doing something with memory that isn't yours.
You can use this jQuery function instead of plus Bootstrap tooltip

if (maxLength == null) { maxLength = 12 }
if (allowDots == null) { allowDots = true }
var selectedOption = $(ddlID).find('option:selected').text();
if (selectedOption.length > maxLength) {
$(ddlID).attr('data-toggle', "tooltip")
.attr('title', selectedOption);
if (allowDots) {
$(ddlID).prev('sup').remove();
$(ddlID).before(
"<sup style='font-size: 9.5pt;position: relative;top: -1px;left: -17px;z-index: 1000;background-color: #f7f7f7;border-radius: 229px;font-weight: bold;color: #666;'>...</sup>"
)
}
}
else if ($(ddlID).attr('title') != null) {

IaaS (Infra as a Service)
IaaS provides the infrastructure such as virtual machines and other resources like virtual-machine disk image library, block and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks etc. Infrastructure as service or IaaS is the basic layer in cloud computing model.
Common examples: DigitalOcean, Linode, Rackspace, Amazon Web Services (AWS), Cisco Metapod, Microsoft Azure, Google Compute Engine (GCE) are some popular examples of Iaas.
PaaS (Platform as a Service)
PaaS or platform as a service model provides you computing platforms which typically includes an operating system, programming language execution environment, database, web server. technically It is a layer on top of IaaS as the second thing you demand after Infrastructure is a platform.
Common examples: AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos.
SaaS (Software as a Service)
In a SaaS, you are provided access to application services installed at a server. You don’t have to worry about installation, maintenance or coding of that software. You can access and operate the software with just your browser. You don’t have to download or install any kind of setup or OS, the software is just available for you to access and operate. The software maintenance or setup or help will be provided by SaaS provider company and you will only have to pay for your usage.
Common examples: Google Apps, Microsoft office365, Google docs, Gmail, WHMCS billing software
Basic difference between IaaS, PaaS & SaaS
Try:
CREATE TABLE foo SELECT * FROM bar LIMIT 0

CREATE TABLE foo SELECT * FROM bar WHERE 1=0
GitLab's "merge request" feature is equivalent to GitHub's "pull request" feature. Both are means of pulling changes from another branch or fork into your branch and merging the changes with your existing code. They are useful tools for code review and change management.
An article from GitLab discusses the differences in naming the feature:
Merge or pull requests are created in a git management application and ask an assigned person to merge two branches. Tools such as GitHub and Bitbucket choose the name pull request since the first manual action would be to pull the feature branch. Tools such as GitLab and Gitorious choose the name merge request since that is the final action that is requested of the assignee. In this article we'll refer to them as merge requests.
A "merge request" should not be confused with the git merge command. Neither should a "pull request" be confused with the git pull command. Both git commands are used behind the scenes in both pull requests and merge requests, but a merge/pull request refers to a much broader topic than just these two commands.
Seems like it can be one of a thousand things.
For me, I was initially pushing master and develop (master had no changes) via SourceTree. Changing this to develop only worked.

To place an emphasis on what everyone else has been saying var foo in top level does not create a global variable. If you want a global variable then write global.foo. but we all know globals are evil.
If you are someone who uses globals like that in a node.js project I was on I would refactor them away for as there are just so few use cases for this (There are a few exceptions but this isn't one).

var app = require('express').createServer();

I know this is an old question, however here is a simple one-liner to switch it on or off depending on its current state:
set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' -name ProxyEnable -value (-not ([bool](get-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' -name ProxyEnable).proxyenable))
This way works and with this structure you can create your own framework and do it with less boilerplate.

I guess you're learning how to Python. The other answers are right. But I am going to answer your main question: "how to calculate percentage in python"
Although it works the way you did it, it doesn´t look very pythonic. Also, what happens if you need to add a new subject? You'll have to add another variable, use another input, etc. I guess you want the average of all marks, so you will also have to modify the count of the subjects everytime you add a new one! Seems a mess...
I´ll throw a piece of code where the only thing you'll have to do is to add the name of the new subject in a list. If you try to understand this simple piece of code, your Python coding skills will experiment a little bump.
#!/usr/local/bin/python2.7
marks = {} #a dictionary, it's a list of (key : value) pairs (eg. "Maths" : 34)
subjects = ["Tamil","English","Maths","Science","Social"] # this is a list
#here we populate the dictionary with the marks for every subject
for subject in subjects:
marks[subject] = input("Enter the " + subject + " marks: ")
#and finally the calculation of the total and the average
total = sum(marks.itervalues())
average = float(total) / len(marks)
print ("The total is " + str(total) + " and the average is " + str(average))
Here you can test the code and experiment with it.
First off:
public class ProfileCollection implements Iterable<Profile> {
Second:
return m_Profiles.get(m_ActiveProfile);
.create
{
background-image: url('somewhere.jpg');
background-repeat: no-repeat;
padding-left: 30px; /* width of the image plus a little extra padding */
display: block; /* may not need this, but I've found I do */
}
Play around with padding and possibly margin until you get your desired result. You can also play with the position of the background image (*nod to Tom Wright) with "background-position" or doing a completely definition of "background" (link to w3).
cast to an int then do a .toString(). It is ugly but it works.
This will do what you want. Fixed sides with 50px-width, and the content fills the remaining area.
<div style="width:100%;">
<div style="width: 50px; float: left;">Left Side</div>
<div style="width: 50px; float: right;">Right Side</div>
<div style="margin-left: 50px; margin-right: 50px;">Content Goes Here</div>
</div>
I'm not a java expert but I solve your problem like this:
@FunctionalInterface
public interface AutoCompleteCallable<T> {
String call(T model) throws Exception;
}
I define the parameter in my special Interface
public <T> void initialize(List<T> entries, AutoCompleteCallable getSearchText) {.......
//call here
String value = getSearchText.call(item);
...
}
Finally, I implement getSearchText method while calling initialize method.
initialize(getMessageContactModelList(), new AutoCompleteCallable() {
@Override
public String call(Object model) throws Exception {
return "custom string" + ((xxxModel)model.getTitle());
}
})
Brief answer to your question: No. You shouldn't call ConfigureAwait(false) at the application level like that.
TL;DR version of the long answer: If you are writing a library where you don't know your consumer and don't need a synchronization context (which you shouldn't in a library I believe), you should always use ConfigureAwait(false). Otherwise, the consumers of your library may face deadlocks by consuming your asynchronous methods in a blocking fashion. This depends on the situation.
Here is a bit more detailed explanation on the importance of ConfigureAwait method (a quote from my blog post):
When you are awaiting on a method with await keyword, compiler generates bunch of code in behalf of you. One of the purposes of this action is to handle synchronization with the UI (or main) thread. The key component of this feature is the
SynchronizationContext.Currentwhich gets the synchronization context for the current thread.SynchronizationContext.Currentis populated depending on the environment you are in. TheGetAwaitermethod of Task looks up forSynchronizationContext.Current. If current synchronization context is not null, the continuation that gets passed to that awaiter will get posted back to that synchronization context.When consuming a method, which uses the new asynchronous language features, in a blocking fashion, you will end up with a deadlock if you have an available SynchronizationContext. When you are consuming such methods in a blocking fashion (waiting on the Task with Wait method or taking the result directly from the Result property of the Task), you will block the main thread at the same time. When eventually the Task completes inside that method in the threadpool, it is going to invoke the continuation to post back to the main thread because
SynchronizationContext.Currentis available and captured. But there is a problem here: the UI thread is blocked and you have a deadlock!
Also, here are two great articles for you which are exactly for your question:
Finally, there is a great short video from Lucian Wischik exactly on this topic: Async library methods should consider using Task.ConfigureAwait(false).
Hope this helps.
After consulting the documentation a bit more, I came up with an answer that supports my needs, but probably won't be as helpful for others. Here it is (without the annoying return true and return false statements :-) )
bool isNumber(string line)
{
return (atoi(line.c_str()));
}
Almost there. In your predicate, you want a relative path, so change
./book[/author/name = 'John']
to either
./book[author/name = 'John']
or
./book[./author/name = 'John']
and you will match your element. Your current predicate goes back to the root of the document to look for an author.
How about statusid = statusid. Null is never equal to null.

Use the command as
java -classpath ".;C:\MyLibs\a\*;D:\MyLibs\b\*" <your-class-name>
The above command will set the mentioned paths to classpath only once for executing the class named TestClass.
If you want to execute more then one classes, then you can follow this
set classpath=".;C:\MyLibs\a\*;D:\MyLibs\b\*"
After this you can execute as many classes as you want just by simply typing
java <your-class-name>
The above command will work till you close the command prompt. But after closing the command prompt, if you will reopen the command prompt and try to execute some classes, then you have to again set the classpath with the help of any of the above two mentioned methods.(First method for executing one class and second one for executing more classes)
If you want to set the classpth only once so that it could work for everytime, then do as follows
1. Right click on "My Computer" icon
2. Go to the "properties"
3. Go to the "Advanced System Settings" or "Advance Settings"
4. Go to the "Environment Variable"
5. Create a new variable at the user variable by giving the information as below
a. Variable Name- classpath
b. Variable Value- .;C:\program files\jdk 1.6.0\bin;C:\MyLibs\a\';C:\MyLibs\b\*
6.Apply this and you are done.
Remember this will work every time. You don't need to explicitly set the classpath again and again.
NOTE: If you want to add some other libs after some day, then don't forget to add a semi-colon at the end of the "variable-value" of the "Environment Variable" and then type the path of your new libs after the semi-colon. Because semi-colon separates the paths of different directories.
Hope this will help you.
Thanks all. I took bits of each of your solutions and made my own.
The final working solution is:
<script type="text/javascript">
$(document).ready(function(){
$.ajax({
url: '<?php bloginfo('template_url'); ?>/functions/twitter.php',
data: "tweets=<?php echo $ct_tweets; ?>&account=<?php echo $ct_twitter; ?>",
success: function(data) {
$('#twitter-loader').remove();
$('#twitter-container').html(data);
}
});
});
</script>
I tried restarting Xcode (7) and nothing (the have you tried switching it off and on again of iOS development for me :-)). I then tried by restarting my box and that worked.
In my case the script was failing when copying a file from a location to another one. I think it could have been related to Finder screwing with writing rights over certain folders.
The above options works for Google big query file also. I exported a table data to goodle cloud storage and downloaded from there. While loading the same to sql server was facing this issue and could successfully load the file after specifying the row delimiter as
ROWTERMINATOR = '0x0a'
Pay attention to header record as well and specify
FIRSTROW = 2
My final block for data file export from google bigquery looks like this.
BULK INSERT TABLENAME
FROM 'C:\ETL\Data\BigQuery\In\FILENAME.csv'
WITH
(
FIRSTROW = 2,
FIELDTERMINATOR = ',', --CSV field delimiter
ROWTERMINATOR = '0x0a',--Files are generated with this row terminator in Google Bigquery
TABLOCK
)

If you just want to filter everything other than the numbers out, the easiest is to use filter_var:
$str = 'In My Cart : 11 items';
$int = (int) filter_var($str, FILTER_SANITIZE_NUMBER_INT);
In practice, the models are used as follows.
In discriminative models, to predict the label y from the training example x, you must evaluate:
which merely chooses what is the most likely class y considering x. It's like we were trying to model the decision boundary between the classes. This behavior is very clear in neural networks, where the computed weights can be seen as a complexly shaped curve isolating the elements of a class in the space.
Now, using Bayes' rule, let's replace the 
in the equation by 
. Since you are just interested in the arg max, you can wipe out the denominator, that will be the same for every y. So, you are left with
which is the equation you use in generative models.
While in the first case you had the conditional probability distribution p(y|x), which modeled the boundary between classes, in the second you had the joint probability distribution p(x, y), since p(x | y) p(y) = p(x, y), which explicitly models the actual distribution of each class.
With the joint probability distribution function, given a y, you can calculate ("generate") its respective x. For this reason, they are called "generative" models.
Is this logically possible??.. I guess the approach that you must take is this way :
Str1 ="test123.00"
Str2 ="yes50.00"
This will be impossible to tackle unless you have delimiter in between test and 123.00
eg: Str1 = "test-123.00"
Then you can split this way
Str2 = Str1.split("-");
This will return you an array of words split with "-"
Then you can do parseFloat(Str2[1]) to get the floating value i.e 123.00
In JavaScript:
pageX, pageY, screenX, screenY, clientX, and clientY returns a number which indicates the number of physical “CSS pixels” a point is from the reference point. The event point is where the user clicked, the reference point is a point in the upper left. These properties return the horizontal and vertical distance from that reference point.
pageX and pageY:
Relative to the top left of the fully rendered content area in the browser. This reference point is below the URL bar and back button in the upper left. This point could be anywhere in the browser window and can actually change location if there are embedded scrollable pages embedded within pages and the user moves a scrollbar.
screenX and screenY:
Relative to the top left of the physical screen/monitor, this reference point only moves if you increase or decrease the number of monitors or the monitor resolution.
clientX and clientY:
Relative to the upper left edge of the content area (the viewport) of the browser window. This point does not move even if the user moves a scrollbar from within the browser.

You probably wanted to ask this before you ran the command. The destructive nature is hinted at by using the same words as in "hard reset".
JasonPy - a few things...
if you stick a button in a loop it will be created over and over and over again... which is probably not what you want. (maybe it is)...
The reason it always gets the last index is lambda events run when you click them - not when the program starts. I'm not sure 100% what you are doing but maybe try storing the value when it's made then call it later with the lambda button.
eg: (don't use this code, just an example)
for entry in stuff_that_is_happening:
value_store[entry] = stuff_that_is_happening
then you can say....
button... command: lambda: value_store[1]
hope this helps!
Update 30th, January 2013, 16 months later:
Starting today, GitHub supports relative links in markup files.
Now you can link directly between different documentation files, whether you view the documentation on GitHub itself, or locally, using a different markup renderer.You want examples of link definitions and how they work? Here's some Markdown for you.
Instead of an absolute link:[a link](https://github.com/user/repo/blob/branch/other_file.md)…you can use a relative link:
[a relative link](other_file.md)and we'll make sure it gets linked to
user/repo/blob/branch/other_file.md.If you were using a workaround like
[a workaround link](repo/blob/master/other_file.md), you'll have to update your documentation to use the new syntax.This also means your documentation can now easily stand on its own, without always pointing to GitHub.
Update December 20th, 2011:
The GitHub markup issue 84 is currently closed by technoweenie, with the comment:
We tried adding a
<base>tag for this, but it causes problems with other relative links on the site.
October 12th, 2011:
If you look at the raw source of the README.md of Markdown itself(!), relative paths don't seem to be supported.
You will find references like:
[r2h]: http://github.com/github/markup/tree/master/lib/github/commands/rest2html
[r2hc]: http://github.com/github/markup/tree/master/lib/github/markups.rb#L13
I wouldn't try to temporarily enable a deprecated feature. According to the MDN documentation for showModalDialog, there's already a polyfill available on Github.
I just used that to add windows.showModalDialog to a legacy enterprise application as a userscript, but you can obviously also add it in the head of the HTML if you have access to the source.
If you want to add the elements with index, you could instead use an array.
String [] test = new String[length];
test[0] = "add";
in iOS Simulator menu, go to Debug -> Location -> Custom Location. There you can set the latitude and longitude and test the app accordingly. This works with mapkit and also with CLLocationManager.
No. You can't send headers after they were sent. Try to use hooks in wordpress
this.myService.getConfig().subscribe(
(res) => console.log(res),
(err) => console.log(err),
() => console.log('done!')
);
If you just need a number that's bigger than all others, you can use
float('inf')
in similar fashion, a number smaller than all others:
float('-inf')
This works in both python 2 and 3.
I've had this problem before, you can go to "advanced" tab of "choose a data source" page and click on "suggested types" button, and set the "number of rows" as much as you want. after that, the type and text qualified are set to the true values.
i applied the above solution and can convert my data to SQL.
Using a mix of feature detection and Useragent string:
var is_opera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
var is_Edge = navigator.userAgent.indexOf("Edge") > -1;
var is_chrome = !!window.chrome && !is_opera && !is_Edge;
var is_explorer= typeof document !== 'undefined' && !!document.documentMode && !is_Edge;
var is_firefox = typeof window.InstallTrigger !== 'undefined';
var is_safari = /^((?!chrome|android).)*safari/i.test(navigator.userAgent);
Usage:
if (is_safari) alert('Safari');
Or for Safari only, use this :
if ( /^((?!chrome|android).)*safari/i.test(navigator.userAgent)) {alert('Its Safari');}
Very simply, you can rename your Python script to "pythonscript.cgi". Post that in your cgi-bin directory, add the appropriate permissions and browse to it.
This is a great link you can start with.
Hope that helps.
EDIT (09/12/2015): The second link has long been removed. Replaced it with one that provides information referenced from the original.
Changing value to defaultValue will resolve it.
Note:
defaultValueis only for the initial load. If you want to initialize theinputthen you should usedefaultValue, but if you want to usestateto change the value then you need to usevalue. Read this for more.
I used value={this.state.input ||""} in input to get rid of that warning.
Try to implement FirebaseInstanceIdService to get refresh token.
Access the registration token:
You can access the token's value by extending FirebaseInstanceIdService. Make sure you have added the service to your manifest, then call getToken in the context of onTokenRefresh, and log the value as shown:
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(refreshedToken);
}
Full Code:
import android.util.Log;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
/**
* Called if InstanceID token is updated. This may occur if the security of
* the previous token had been compromised. Note that this is called when the InstanceID token
* is initially generated so this is where you would retrieve the token.
*/
// [START refresh_token]
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(refreshedToken);
}
// [END refresh_token]
/**
* Persist token to third-party servers.
*
* Modify this method to associate the user's FCM InstanceID token with any server-side account
* maintained by your application.
*
* @param token The new token.
*/
private void sendRegistrationToServer(String token) {
// Add custom implementation, as needed.
}
}
See my answer here.
EDITS:
You shouldn't be starting a FirebaseInstanceIdService yourself.
It will Called when the system determines that the tokens need to be refreshed. The application should call getToken() and send the tokens to all application servers.
This will not be called very frequently, it is needed for key rotation and to handle Instance ID changes due to:
The system will throttle the refresh event across all devices to avoid overloading application servers with token updates.
Try below way:
you'd call FirebaseInstanceID.getToken() anywhere off your main thread (whether it is a service, AsyncTask, etc), store the returned token locally and send it to your server. Then whenever
onTokenRefresh()is called, you'd call FirebaseInstanceID.getToken() again, get a new token, and send that up to the server (probably including the old token as well so your server can remove it, replacing it with the new one).
I think in 2018 it's better to use the input event.
-
As the WHATWG Spec describes (https://html.spec.whatwg.org/multipage/indices.html#event-input-input):
Fired at controls when the user changes the value (see also the change event)
-
Here's an example of how to use it:
<input type="text" oninput="handleValueChange()">
Use del /F /Q to force deletion of read-only files (/F) and directories and not ask to confirm (/Q) when deleting via wildcard.
In my case, I was looking for a solution that allows one of the navbar items to be right aligned. In order to do this, you must add style="width:100%;" to the <ul class="navbar-nav"> and then add the ml-auto class to your navbar item.
The previous answers were in the right track, but the complete answer for this is going to Disabling rules only for a group of files, there you'll find the documentation needed to disable/enable rules for certain folders (Because in some cases you don't want to ignore the whole thing, only disable certain rules). Example:
{
"env": {},
"extends": [],
"parser": "",
"plugins": [],
"rules": {},
"overrides": [
{
"files": ["test/*.spec.js"], // Or *.test.js
"rules": {
"require-jsdoc": "off"
}
}
],
"settings": {}
}
You can use String.split(String regex):
String input = "aabbab";
String[] parts = input.split("(?!^)");
Setting the logger name as requests or requests.urllib3 did not work for me. I had to specify the exact logger name to change the logging level.
First See which loggers you have defined, to see which ones you want to remove
print(logging.Logger.manager.loggerDict)
And you will see something like this:
{...'urllib3.poolmanager': <logging.Logger object at 0x1070a6e10>, 'django.request': <logging.Logger object at 0x106d61290>, 'django.template': <logging.Logger object at 0x10630dcd0>, 'django.server': <logging.Logger object at 0x106dd6a50>, 'urllib3.connection': <logging.Logger object at 0x10710a350>,'urllib3.connectionpool': <logging.Logger object at 0x106e09690> ...}
Then configure the level for the exact logger:
'loggers': {
'': {
'handlers': ['default'],
'level': 'DEBUG',
'propagate': True
},
'urllib3.connectionpool': {
'handlers': ['default'],
'level': 'WARNING',
'propagate' : False
},
You can try using the a backslash followed by a "u" and then the unicode value for the character, for example the unicode value of the double quote is
" -> U+0022
Therefore if you were setting it as part of text in XML in android it would look something like this,
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text=" \u0022 Showing double quotes \u0022 "/>
This would produce a text in the TextView roughly something like this
" Showing double quotes "
You can find unicode of most symbols and characters here www.unicode-table.com/en
Most answers here are correct but taken a bit out of context, so I will provide a full-fledged answer which works for Asp.Net Core 3.1. For completeness' sake:
[Route("health")]
[ApiController]
public class HealthController : Controller
{
[HttpGet("some_health_url")]
public ActionResult SomeHealthMethod() {}
}
[Route("v2")]
[ApiController]
public class V2Controller : Controller
{
[HttpGet("some_url")]
public ActionResult SomeV2Method()
{
return RedirectToAction("SomeHealthMethod", "Health"); // omit "Controller"
}
}
If you try to use any of the url-specific strings, e.g. "some_health_url", it will not work!
Regarding your Update.
The concept of CRUD I believe has caused some confusion regarding API design. CRUD is a general low level concept for basic operations to perform on data, and HTTP verbs are just request methods (created 21 years ago) that may or may not map to a CRUD operation. In fact, try to find the presence of the CRUD acronym in the HTTP 1.0/1.1 specification.
A very well explained guide that applies a pragmatic convention can be found in the Google cloud platform API documentation. It describes the concepts behind the creation of a resource based API, one that emphasizes a big amount of resources over operations, and includes the use cases that you are describing. Although is a just a convention design for their product, I think it makes a lot of sense.
The base concept here (and one that produces a lot of confusion) is the mapping between "methods" and HTTP verbs. One thing is to define what "operations" (methods) your API will do over which types of resources (for example, get a list of customers, or send an email), and another are the HTTP verbs. There must be a definition of both, the methods and the verbs that you plan to use and a mapping between them.
It also says that, when an operation does not map exactly with a standard method (List, Get, Create, Update, Delete in this case), one may use "Custom methods", like BatchGet, which retrieves several objects based on several object id input, or SendEmail.
SecretKeySpec expects a key, not a password. See belowThe problem is number 1: you are passing the password instead of the key.
AES only supports key sizes of 16, 24 or 32 bytes. You either need to provide exactly that amount or you derive the key from what you type in.
There are different ways to derive the key from a passphrase. Java provides a PBKDF2 implementation for such a purpose.
I used erickson's answer to paint a complete picture (only encryption, since the decryption is similar, but includes splitting the ciphertext):
SecureRandom random = new SecureRandom();
byte[] salt = new byte[16];
random.nextBytes(salt);
KeySpec spec = new PBEKeySpec("password".toCharArray(), salt, 65536, 256); // AES-256
SecretKeyFactory f = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
byte[] key = f.generateSecret(spec).getEncoded();
SecretKeySpec keySpec = new SecretKeySpec(key, "AES");
byte[] ivBytes = new byte[16];
random.nextBytes(ivBytes);
IvParameterSpec iv = new IvParameterSpec(ivBytes);
Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");
c.init(Cipher.ENCRYPT_MODE, keySpec, iv);
byte[] encValue = c.doFinal(valueToEnc.getBytes());
byte[] finalCiphertext = new byte[encValue.length+2*16];
System.arraycopy(ivBytes, 0, finalCiphertext, 0, 16);
System.arraycopy(salt, 0, finalCiphertext, 16, 16);
System.arraycopy(encValue, 0, finalCiphertext, 32, encValue.length);
return finalCiphertext;
Other things to keep in mind:
AES is not appropriate in such a case, because different JVMs/JCE providers may use different defaults for mode of operation and padding. Use AES/CBC/PKCS5Padding. Don't use ECB mode, because it is not semantically secure.cipherInstance.getIV().No need to do so much works..
var query = from c in obj.tbCourses
where ...
select c;
Then you can use:
List<course> list_course= query.ToList<course>();
It works fine for me.
For the revised question of how to read in configuration parameters, I'd strongly recommend saving yourself some time and effort and use ConfigParser or (my preferred tool) ConfigObj.
They can do everything you need, they're easy to use, and someone else has already worried about how to get them to work properly!
The following documentation from the Docker website shows how to implement an SSH service in a docker container. It should be easily adaptable for your service:
A variation on this question has also been asked here:
sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password password your_password'
sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password your_password'
sudo apt-get -y install mysql-server
For specific versions, such as mysql-server-5.6, you'll need to specify the version in like this:
sudo debconf-set-selections <<< 'mysql-server-5.6 mysql-server/root_password password your_password'
sudo debconf-set-selections <<< 'mysql-server-5.6 mysql-server/root_password_again password your_password'
sudo apt-get -y install mysql-server-5.6
For mysql-community-server, the keys are slightly different:
sudo debconf-set-selections <<< 'mysql-community-server mysql-community-server/root-pass password your_password'
sudo debconf-set-selections <<< 'mysql-community-server mysql-community-server/re-root-pass password your_password'
sudo apt-get -y install mysql-community-server
Replace your_password with the desired root password. (it seems your_password can also be left blank for a blank root password.)
If your shell doesn't support here-strings (zsh, ksh93 and bash support them), use:
echo ... | sudo debconf-set-selections
git push --all
is the canonical way to push everything to a new bare repository.
Another way to do the same thing is to create your new, non-bare repository and then make a bare clone with
git clone --bare
then use
git remote add origin <new-remote-repo>
in the original (non-bare) repository.
If you want to remove the file from the remote repo, first remove it from your project with --cache option and then push it:
git rm --cache /path/to/file
git commit -am "Remove file"
git push
(This works even if the file was added to the remote repo some commits ago) Remember to add to .gitignore the file extensions that you don't want to push.
I think that a best understanding about this problem is in this example: http://jsfiddle.net/TAHDb/
I am doing a simple thing here:
Have a interval of 1 sec and each time hide the first span and move it to last, and show the 2nd span.
If you stay on page it works as it is supposed. But if you hide the tab for some seconds, when you get back you will see a weired thing.
Its like all events that didn't ucur during the time you were inactive now will ocur all in 1 time. so for some few seconds you will get like X events. they are so quick that its possible to see all 6 spans at once.
So it seams chrome only delays the events, so when you get back all events will occur but all at once...
A pratical application were this ocur iss for a simple slideshow. Imagine the numbers being Images, and if user stay with tab hidden when he came back he will see all imgs floating, Totally mesed.
To fix this use the stop(true,true) like pimvdb told. THis will clear the event queue.
If the 2nd company is happy for you to access their content in an IFrame then they need to take the restriction off - they can do this fairly easily in the IIS config.
There's nothing you can do to circumvent it and anything that does work should get patched quickly in a security hotfix. You can't tell the browser to just render the frame if the source content header says not allowed in frames. That would make it easier for session hijacking.
If the content is GET only you don't post data back then you could get the page server side and proxy the content without the header, but then any post back should get invalidated.

Just to contribute with my approach. As already answered, RetryPolicy is the way to go. But if you need a policy different the than default for all your requests, you can set it in a base Request class, so you don't need to set the policy for all the instances of your requests.
Something like this:
public class BaseRequest<T> extends Request<T> {
public BaseRequest(int method, String url, Response.ErrorListener listener) {
super(method, url, listener);
setRetryPolicy(getMyOwnDefaultRetryPolicy());
}
}
In my case I have a GsonRequest which extends from this BaseRequest, so I don't run the risk of forgetting to set the policy for an specific request and you can still override it if some specific request requires to.

# * you have to change '$ROLE_LOCAL', '$ROLE_REMOTE' and '$DB'
# strings with your desired names

for(int i = 0; i < ListSpinner.size(); i++){
if(ListSpinner.get(i).getValueEquals().equals(myString)){

using:
int index=selectSpinnerValue(ListOfSpinner,StringEquals);

What you have done is created a new anonymous function that takes a single parameter which then gets assigned to the local variable myMessage inside the function. Since no arguments are actually passed, and arguments which aren't passed a value become null, your function just does alert(null).
Some ideas:
Use git mergetool to split the merge files into original and new parts. Hopefully one of those is the file with your non-stash changes in it.
Apply the diff of the stash in reverse, to undo just those changes. You'll probably have to manually split out the files with the merge conflicts (which hopefully the above trick will work for).
I didn't test either of these, so I don't know for sure of they will work.

You can make use of the plusMonths and minusDays methods in Java 8:
// Parse your date into a LocalDate
LocalDate parsed = LocalDate.parse("1/13/2012", DateTimeFormatter.ofPattern("M/d/yyyy"));
// We only care about its year and month, set the date to first date of that month
LocalDate localDate = LocalDate.of(parsed.getYear(), parsed.getMonth(), 1);
// Add one month, subtract one day
System.out.println(localDate.plusMonths(1).minusDays(1)); // 2012-01-31

When you say "is there an easier way to... trust this cert", that's exactly what you're doing by adding the cert to your Java trust store. And this is very, very easy to do, and there's nothing you need to do within your client app to get that trust store recognized or utilized.
On your client machine, find where your cacerts file is (that's your default Java trust store, and is, by default, located at <java-home>/lib/security/certs/cacerts.
Then, type the following:
keytool -import -alias <Name for the cert> -file <the .cer file> -keystore <path to cacerts>
That will import the cert into your trust store, and after this, your client app will be able to connect to your Grizzly HTTPS server without issue.
If you don't want to import the cert into your default trust store -- i.e., you just want it to be available to this one client app, but not to anything else you run on your JVM on that machine -- then you can create a new trust store just for your app. Instead of passing keytool the path to the existing, default cacerts file, pass keytool the path to your new trust store file:
keytool -import -alias <Name for the cert> -file <the .cer file> -keystore <path to new trust store>
You'll be asked to set and verify a new password for the trust store file. Then, when you start your client app, start it with the following parameters:
java -Djavax.net.ssl.trustStore=<path to new trust store> -Djavax.net.ssl.trustStorePassword=<trust store password>
Easy cheesy, really.
Arrays have an implicit member variable holding the length:
for(int i=0; i<myArray.length; i++) {

System.out.println(o);
}

Using the browser's parser is the probably the best bet in current browsers. The following will work, with the following caveats:
<div> element. HTML contained within <body> or <html> or <head> tags is not valid within a <div> and may therefore not be parsed correctly.textContent (the DOM standard property) and innerText (non-standard) properties are not identical. For example, textContent will include text within a <script> element while innerText will not (in most browsers). This only affects IE <=8, which is the only major browser not to support textContent.<script> elements.null<img onerror='alert(\"could run arbitrary JS here\")' src=bogus>Code:
var html = "<p>Some HTML</p>";
var div = document.createElement("div");
div.innerHTML = html;
var text = div.textContent || div.innerText || "";
Here's an approach:
HTML:
<div id="1">
My Content 1
</div>
<div id="2" style="display:none;">
My Dynamic Content
</div>
<button id="btnClick">Click me!</button>
jQuery:
$('#btnClick').on('click',function(){
if($('#1').css('display')!='none'){
$('#2').html('Here is my dynamic content').show().siblings('div').hide();
}else if($('#2').css('display')!='none'){
$('#1').show().siblings('div').hide();
}
});

In Python, execution does NOT have to begin at main. The first line of "executable code" is executed first.
def main():
print("main code")
def meth1():
print("meth1")
meth1()
if __name__ == "__main__":main() ## with if
Output -
meth1
main code
More on main() - http://ibiblio.org/g2swap/byteofpython/read/module-name.html
A module's __name__
Every module has a name and statements in a module can find out the name of its module. This is especially handy in one particular situation - As mentioned previously, when a module is imported for the first time, the main block in that module is run. What if we want to run the block only if the program was used by itself and not when it was imported from another module? This can be achieved using the name attribute of the module.
Using a module's __name__
#!/usr/bin/python
# Filename: using_name.py
if __name__ == '__main__':
print 'This program is being run by itself'
else:
print 'I am being imported from another module'
Output -
$ python using_name.py
This program is being run by itself
$ python
>>> import using_name
I am being imported from another module
>>>
How It Works -
Every Python module has it's __name__ defined and if this is __main__, it implies that the module is being run standalone by the user and we can do corresponding appropriate actions.
You can set up a developer application and set the url to localhost.com:port Make sure to map localhost.com to localhost on your hosts file

Here is a solution using the plyr package.
The following line of code essentially tells ddply to first group your data by Group, and then within each group returns a subset where the Score equals the maximum score in that group.
library(plyr)
ddply(data, .(Group), function(x)x[x$Score==max(x$Score), ])
Group Score Info
1 1 3 c
2 2 4 d
And, as @SachaEpskamp points out, this can be further simplified to:
ddply(df, .(Group), function(x)x[which.max(x$Score), ])
(which also has the advantage that which.max will return multiple max lines, if there are any).

Thanks for commenting, I understand what you mean but I didn't want to check old values. I just wanted to get a pointer to that view.
Looking at someone else's code I have just found a workaround, you can access the root of a layout using LayoutInflater.
The code is the following, where this is an Activity:
final LayoutInflater factory = getLayoutInflater();
final View textEntryView = factory.inflate(R.layout.landmark_new_dialog, null);
landmarkEditNameView = (EditText) textEntryView.findViewById(R.id.landmark_name_dialog_edit);
You need to get the inflater for this context, access the root view through the inflate method and finally call findViewById on the root view of the layout.
Hope this is useful for someone! Bye
Offset Means "the amount or distance by which something is out of line". Margin or Borders are something which makes the actual height or width of an HTML element "out of line". It will help you to remember that :
- offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar.
On the other hand, clientHeight is something which is you can say kind of the opposite of OffsetHeight. It doesn't include the border or margins. It does include the padding because it is something that resides inside of the HTML container, so it doesn't count as extra measurements like margin or border. So :
- clientHeight property returns the viewable height of an element in pixels, including padding, but not the border, scrollbar or margin.
ScrollHeight is all the scrollable area, so your scroll will never run over your margin or border, so that's why scrollHeight doesn't include margin or borders but yeah padding does. So:
- scrollHeight value is equal to the minimum height the element would require in order to fit all the content in the viewport without using a vertical scrollbar. The height is measured in the same way as clientHeight: it includes the element's padding, but not its border, margin or horizontal scrollbar.
I think the answer to the question is because .net uses string interning something that might cause equal strings to point to the same object (since a strings are mutable this is not a problem)
(I'm not talking about the overridden equality operator on the string class)
The key for me to be able to connect was to use the "ec2-user" user rather than root. I.e.:

There is a (somewhat) related question on StackOverflow:
Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.
More generally, the reason for the Exception
TypeError: Invalid dimensions for image data
is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!
You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):
from __future__ import print_function
import numpy as np
def valid_imshow_data(data):
data = np.asarray(data)
if data.ndim == 2:
return True
elif data.ndim == 3:
if 3 <= data.shape[2] <= 4:
return True
else:
print('The "data" has 3 dimensions but the last dimension '
'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
''.format(data.shape[2]))
return False
else:
print('To visualize an image the data must be 2 dimensional or '
'3 dimensional, not "{}".'
''.format(data.ndim))
return False
In your case:
>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False
The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.
In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()
import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0) # or axis=1
plt.imshow(a)
plt.show()
or just use something that accepts 1D arrays like plot:
a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()
There are some disadvantages of CLUSTERED INDEXES vs UNIQUE INDEXES.
As already stated, a CLUSTERED INDEX physically orders the data in the table.
This mean that when you have a lot if inserts or deletes on a table containing a clustered index, everytime (well, almost, depending on your fill factor) you change the data, the physical table needs to be updated to stay sorted.
In relative small tables, this is fine, but when getting to tables that have GB's worth of data, and insertrs/deletes affect the sorting, you will run into problems.
I think your problem is inside CheckCircular, in the while condition:
Assume you have 2 nodes, first N1 and N2 point to the same node, then N1 points to the second node (last) and N2 points to null (because it's N2.next.next). In the next loop, you try to call the 'next' method on N2, but N2 is null. There you have it, NullPointerException
If you want the child divs to fit the parent size, you should put a margin at least of the size of the child borders on the child divs (child.margin >= child.bordersize).
For this example, just remove the width:100%; and the height:100% in #one and remove the width:100% in #two. It should be something like this:
html, body {width:100%; height:100%; margin:0; padding:0;}
.border {border:1px solid black;}
.margin {margin:5px;}
\#one {}
\#two {height:50px;}
\#three {width:100px; height:100%;}
