You Can Try this
import ftplib
path = 'pub/Health_Statistics/NCHS/nhanes/2001-2002/'
filename = 'L28POC_B.xpt'
ftp = ftplib.FTP("Server IP")
ftp.login("UserName", "Password")
ftp.cwd(path)
ftp.retrbinary("RETR " + filename, open(filename, 'wb').write)
ftp.quit()
rootView
is just a view pointing to my root view in this case a relative layout
:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/addresses_confirm_root_view"
android:background="@color/WHITE_CLR">
RelativeLayout rootView = (RelativeLayout) findViewById(R.id.addresses_confirm_root_view);
getViewTreeObserver()
rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
int heightDiff = rootView.getRootView().getHeight() - rootView.getHeight();
if (heightDiff > 100) { // Value should be less than keyboard's height
Log.e("MyActivity", "keyboard opened");
} else {
Log.e("MyActivity", "keyboard closed");
}
}
});
The break
keyword does exactly that. Here is a contrived example:
public static void main(String[] args) {
int i = 0;
while (i++ < 10) {
if (i == 5) break;
}
System.out.println(i); //prints 5
}
If you were actually using nested loops, you would be able to use labels.
Yes. The querystring is also encrypted with SSL. Nevertheless, as this article shows, it isn't a good idea to put sensitive information in the URL. For example:
URLs are stored in web server logs - typically the whole URL of each request is stored in a server log. This means that any sensitive data in the URL (e.g. a password) is being saved in clear text on the server
Here are two ways:
In HTML:
<div class="ics">⛱</div>
This will result into ⛱
In Css:
.ics::before {content: "\9969;"}
with HTML code <div class="ics"></div>
This also results in ⛱
One more important thing needs to be highlighted. It's better to use params
because it is better for performance. When you call a method with params
argument and passed to it nothing:
public void ExampleMethod(params string[] args)
{
// do some stuff
}
call:
ExampleMethod();
Then a new versions of the .Net Framework do this (from .Net Framework 4.6):
ExampleMethod(Array.Empty<string>());
This Array.Empty
object can be reused by framework later, so there are no needs to do redundant allocations. These allocations will occur when you call this method like this:
ExampleMethod(new string[] {});
Set up a flux container
simple example
import alt from './../../alt.js';
class PostActions {
constructor(){
this.generateActions('setMessages');
}
setMessages(indexArray){
this.actions.setMessages(indexArray);
}
}
export default alt.createActions(PostActions);
store looks like this
class PostStore{
constructor(){
this.messages = [];
this.bindActions(MessageActions);
}
setMessages(messages){
this.messages = messages;
}
}
export default alt.createStore(PostStore);
Then every component that listens to the store can share this variable In your constructor is where you should grab it
constructor(props){
super(props);
//here is your data you get from the store, do what you want with it
var messageStore = MessageStore.getState();
}
componentDidMount() {
MessageStore.listen(this.onMessageChange.bind(this));
}
componentWillUnmount() {
MessageStore.unlisten(this.onMessageChange.bind(this));
}
onMessageChange(state){
//if the data ever changes each component listining will be notified and can do the proper processing.
}
This way, you can share you data across the app without every component having to communicate with each other.
Heres a variant on WWs answer, it includes partitions and sub-partitions as others above have suggested, plus a column to show the TYPE: Table/Index/LOB etc
SELECT
owner, "Type", table_name "Name", TRUNC(sum(bytes)/1024/1024) Meg
FROM
( SELECT segment_name table_name, owner, bytes, 'Table' as "Type"
FROM dba_segments
WHERE segment_type in ('TABLE','TABLE PARTITION','TABLE SUBPARTITION')
UNION ALL
SELECT i.table_name, i.owner, s.bytes, 'Index' as "Type"
FROM dba_indexes i, dba_segments s
WHERE s.segment_name = i.index_name
AND s.owner = i.owner
AND s.segment_type in ('INDEX','INDEX PARTITION','INDEX SUBPARTITION')
UNION ALL
SELECT l.table_name, l.owner, s.bytes, 'LOB' as "Type"
FROM dba_lobs l, dba_segments s
WHERE s.segment_name = l.segment_name
AND s.owner = l.owner
AND s.segment_type IN ('LOBSEGMENT','LOB PARTITION','LOB SUBPARTITION')
UNION ALL
SELECT l.table_name, l.owner, s.bytes, 'LOB Index' as "Type"
FROM dba_lobs l, dba_segments s
WHERE s.segment_name = l.index_name
AND s.owner = l.owner
AND s.segment_type = 'LOBINDEX')
WHERE owner in UPPER('&owner')
GROUP BY table_name, owner, "Type"
HAVING SUM(bytes)/1024/1024 > 10 /* Ignore really small tables */
ORDER BY SUM(bytes) desc;
You might get the error with the latest android gradle plugin (3.0):
Cannot set the value of read-only property 'outputFile'
According to the migration guide, we should use the following approach now:
applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "${applicationName}_${variant.buildType.name}_${defaultConfig.versionName}.apk"
}
}
Note 2 main changes here:
all
is used now instead of each
to iterate over the variant outputs.outputFileName
property is used instead of mutating a file reference.A handle is a unique identifier for an object managed by Windows. It's like a pointer, but not a pointer in the sence that it's not an address that could be dereferenced by user code to gain access to some data. Instead a handle is to be passed to a set of functions that can perform actions on the object the handle identifies.
This is also possible:
a {
all: unset;
}
unset: This keyword indicates to change all the properties applying to the element or the element's parent to their parent value if they are inheritable or to their initial value if not. unicode-bidi and direction values are not affected.

(e.g)
<script

If you need to do it programmatically to change (for example) the speed based on certain conditions on perhaps only one of many carousels, you could do something like this:
If the Html is like this:
<div id="theSlidesList" class="carousel-inner" role="listbox">
<div id="Slide_00" class="item active"> ...
<div id="Slide_01" class="item"> ...
...
</div>
JavaScript would be like this:
$( "#theSlidesList" ).find( ".item" ).css( "-webkit-transition", "transform 1.9s ease-in-out 0s" ).css( "transition", "transform 1.9s ease-in-out 0s" )
Add more .css( ... ) to include other browsers.
So you want to split on spaces, and on commas and periods that aren't surrounded by numbers. This should work:
r" |(?<![0-9])[.,](?![0-9])"
As others have hinted, you should consider dumping org.json's library. It's pretty much obsolete these days, and trying to work around its problems is waste of time.
But to specific question; type variable T just does not have any information to help you, as it is little more than compile-time information. Instead you need to pass actual class (as 'Class cls' argument), and you can then create an instance with 'cls.newInstance()'.
Ternary operators are just shorthand. They compile into the equivalent if-else
statement, meaning they will be exactly the same.
In the new ES2015 standard for JavaScript (formerly called ES6), objects can be created with computed keys: Object Initializer spec.
The syntax is:
var obj = {
[myKey]: value,
}
If applied to the OP's scenario, it would turn into:
stuff = function (thing, callback) {
var inputs = $('div.quantity > input').map(function(){
return {
[this.attr('name')]: this.attr('value'),
};
})
callback(null, inputs);
}
Note: A transpiler is still required for browser compatiblity.
Using Babel or Google's traceur, it is possible to use this syntax today.
In earlier JavaScript specifications (ES5 and below), the key in an object literal is always interpreted literally, as a string.
To use a "dynamic" key, you have to use bracket notation:
var obj = {};
obj[myKey] = value;
In your case:
stuff = function (thing, callback) {
var inputs = $('div.quantity > input').map(function(){
var key = this.attr('name')
, value = this.attr('value')
, ret = {};
ret[key] = value;
return ret;
})
callback(null, inputs);
}
You can specify the row index in the read_csv or read_html constructors via the header
parameter which represents Row number(s) to use as the column names, and the start of the data
. This has the advantage of automatically dropping all the preceding rows which supposedly are junk.
import pandas as pd
from io import StringIO
In[1]
csv = '''junk1, junk2, junk3, junk4, junk5
junk1, junk2, junk3, junk4, junk5
pears, apples, lemons, plums, other
40, 50, 61, 72, 85
'''
df = pd.read_csv(StringIO(csv), header=2)
print(df)
Out[1]
pears apples lemons plums other
0 40 50 61 72 85
One of the scenarios I found useful to use CTE is when you want to get DISTINCT rows of data based on one or more columns but return all columns in the table. With a standard query you might first have to dump the distinct values into a temp table and then try to join them back to the original table to retrieve the rest of the columns or you might write an extremely complex partition query that can return the results in one run but in most likelihood, it will be unreadable and cause performance issue.
But by using CTE (as answered by Tim Schmelter on Select the first instance of a record)
WITH CTE AS(
SELECT myTable.*
, RN = ROW_NUMBER()OVER(PARTITION BY patientID ORDER BY ID)
FROM myTable
)
SELECT * FROM CTE
WHERE RN = 1
As you can see, this is much easier to read and maintain. And in comparison to other queries, is much better at performance.
According the W3Schools you might use JavaScript for disabled checkbox.
<!-- Checkbox who determine if the other checkbox must be disabled -->
<input type="checkbox" id="checkboxDetermine">
<!-- The other checkbox conditionned by the first checkbox -->
<input type="checkbox" id="checkboxConditioned">
<!-- JS Script -->
<script type="text/javascript">
// Get your checkbox who determine the condition
var determine = document.getElementById("checkboxDetermine");
// Make a function who disabled or enabled your conditioned checkbox
var disableCheckboxConditioned = function () {
if(determine.checked) {
document.getElementById("checkboxConditioned").disabled = true;
}
else {
document.getElementById("checkboxConditioned").disabled = false;
}
}
// On click active your function
determine.onclick = disableCheckboxConditioned;
disableCheckboxConditioned();
</script>
You can see the demo working here : http://jsfiddle.net/antoinesubit/vptk0nh6/
Use the requests library, pretty print the results so you can better locate the keys/values you want to extract, and then use nested for loops to parse the data. In the example I extract step by step driving directions.
import json, requests, pprint
url = 'http://maps.googleapis.com/maps/api/directions/json?'
params = dict(
origin='Chicago,IL',
destination='Los+Angeles,CA',
waypoints='Joplin,MO|Oklahoma+City,OK',
sensor='false'
)
data = requests.get(url=url, params=params)
binary = data.content
output = json.loads(binary)
# test to see if the request was valid
#print output['status']
# output all of the results
#pprint.pprint(output)
# step-by-step directions
for route in output['routes']:
for leg in route['legs']:
for step in leg['steps']:
print step['html_instructions']
Now you can hover the key input and select "file", which will give you a file selector in the value column:
JACKSON Library
One option would be to use Jackson library. First import the latest version (now is):
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.7.0</version>
</dependency>
Then, you can implement the correct answer as follows:
import com.fasterxml.jackson.databind.ObjectMapper;
public final class JSONUtils {
private JSONUtils(){}
public static boolean isJSONValid(String jsonInString ) {
try {
final ObjectMapper mapper = new ObjectMapper();
mapper.readTree(jsonInString);
return true;
} catch (IOException e) {
return false;
}
}
}
Google GSON option
Another option is to use Google Gson. Import the dependency:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.5</version>
</dependency>
Again, you can implement the proposed solution as:
import com.google.gson.Gson;
public final class JSONUtils {
private static final Gson gson = new Gson();
private JSONUtils(){}
public static boolean isJSONValid(String jsonInString) {
try {
gson.fromJson(jsonInString, Object.class);
return true;
} catch(com.google.gson.JsonSyntaxException ex) {
return false;
}
}
}
A simple test follows here:
//A valid JSON String to parse.
String validJsonString = "{ \"developers\": [{ \"firstName\":\"Linus\" , \"lastName\":\"Torvalds\" }, " +
"{ \"firstName\":\"John\" , \"lastName\":\"von Neumann\" } ]}";
// Invalid String with a missing parenthesis at the beginning.
String invalidJsonString = "\"developers\": [ \"firstName\":\"Linus\" , \"lastName\":\"Torvalds\" }, " +
"{ \"firstName\":\"John\" , \"lastName\":\"von Neumann\" } ]}";
boolean firstStringValid = JSONUtils.isJSONValid(validJsonString); //true
boolean secondStringValid = JSONUtils.isJSONValid(invalidJsonString); //false
Please, observe that there could be a "minor" issue due to trailing commas that will be fixed in release 3.0.0
.
if you want to do screen capture from Java code in Android app AFAIK you must have Root provileges.
For integers you can use Integer.signum()
Returns the signum function of the specified int value. (The return value is -1 if the specified value is negative; 0 if the specified value is zero; and 1 if the specified value is positive.)
The regex way:
var matches = !!location.href.match(/franky/); //a boolean value now
Or in a simple statement you could use:
if (location.href.match(/franky/)) {
I use this to test whether the website is running locally or on a server:
location.href.match(/(192.168|localhost).*:1337/)
This checks whether the href contains either 192.168
or localhost
AND is followed by :1337
.
As you can see, using regex has its advantages over the other solutions when the condition gets a bit trickier.
I tried to formulate my version of url. My requirement was to capture instances in a String where possible url can be cse.uom.ac.mu - noting that it is not preceded by http nor www
String regularExpression = "((((ht{2}ps?://)?)((w{3}\\.)?))?)[^.&&[a-zA-Z0-9]][a-zA-Z0-9.-]+[^.&&[a-zA-Z0-9]](\\.[a-zA-Z]{2,3})";
assertTrue("www.google.com".matches(regularExpression));
assertTrue("www.google.co.uk".matches(regularExpression));
assertTrue("http://www.google.com".matches(regularExpression));
assertTrue("http://www.google.co.uk".matches(regularExpression));
assertTrue("https://www.google.com".matches(regularExpression));
assertTrue("https://www.google.co.uk".matches(regularExpression));
assertTrue("google.com".matches(regularExpression));
assertTrue("google.co.uk".matches(regularExpression));
assertTrue("google.mu".matches(regularExpression));
assertTrue("mes.intnet.mu".matches(regularExpression));
assertTrue("cse.uom.ac.mu".matches(regularExpression));
//cannot contain 2 '.' after www
assertFalse("www..dr.google".matches(regularExpression));
//cannot contain 2 '.' just before com
assertFalse("www.dr.google..com".matches(regularExpression));
// to test case where url www must be followed with a '.'
assertFalse("www:google.com".matches(regularExpression));
// to test case where url www must be followed with a '.'
//assertFalse("http://wwwe.google.com".matches(regularExpression));
// to test case where www must be preceded with a '.'
assertFalse("https://[email protected]".matches(regularExpression));
I had this code in a fragment and it was crashing if I try to come back to this fragment
if (mRootView == null) {
mRootView = inflater.inflate(R.layout.fragment_main, container, false);
}
after gathering the answers on this thread, I realised that mRootView's parent still have mRootView as child. So, this was my fix.
if (mRootView == null) {
mRootView = inflater.inflate(R.layout.fragment_main, container, false);
} else {
((ViewGroup) mRootView.getParent()).removeView(mRootView);
}
hope this helps
This is visual representation of how performances compare to each other.
Another option is to create an additional "errata commit" (and push) which references the commit object that contains the error -- the new errata commit also provides the correction. An errata commit is a commit with no substantive code changes but an important commit message -- for example, add one space character to your readme file and commit that change with the important commit message, or use the git option --allow-empty
. It's certainly easier and safer than rebasing, it doesn't modify true history, and it keeps the branch tree clean (using amend
is also a good choice if you are correcting the most recent commit, but an errata commit may be a good choice for older commits). This type of thing so rarely happens that simply documenting the mistake is good enough. In the future, if you need to search through a git log for a feature keyword, the original (erroneous) commit may not appear because the wrong keyword was used in that original commit (the original typo) -- however, the keyword will appear in the errata commit which will then point you to the original commit that had the typo. Here's an example:
$ git log commit 0c28141c68adae276840f17ccd4766542c33cf1d Author: First Last Date: Wed Aug 8 15:55:52 2018 -0600 Errata commit: This commit has no substantive code change. This commit is provided only to document a correction to a previous commit message. This pertains to commit object e083a7abd8deb5776cb304fa13731a4182a24be1 Original incorrect commit message: Changed background color to red Correction (*change highlighted*): Changed background color to *blue* commit 032d0ff0601bff79bdef3c6f0a02ebfa061c4ad4 Author: First Last Date: Wed Aug 8 15:43:16 2018 -0600 Some interim commit message commit e083a7abd8deb5776cb304fa13731a4182a24be1 Author: First Last Date: Wed Aug 8 13:31:32 2018 -0600 Changed background color to red

./
refers to the current working directory, except in the require()
function. When using require()
, it translates ./
to the directory of the current file called. __dirname
is always the directory of the current file.
For example, with the following file structure
/home/user/dir/files/config.json
{
"hello": "world"
}
/home/user/dir/files/somefile.txt
text file
/home/user/dir/dir.js
var fs = require('fs');
console.log(require('./files/config.json'));
console.log(fs.readFileSync('./files/somefile.txt', 'utf8'));
If I cd
into /home/user/dir
and run node dir.js
I will get
{ hello: 'world' }
text file
But when I run the same script from /home/user/
I get
{ hello: 'world' }
Error: ENOENT, no such file or directory './files/somefile.txt'
at Object.openSync (fs.js:228:18)
at Object.readFileSync (fs.js:119:15)
at Object.<anonymous> (/home/user/dir/dir.js:4:16)
at Module._compile (module.js:432:26)
at Object..js (module.js:450:10)

at Function._load (module.js:310:12)
at Array.0 (module.js:470:10)
at EventEmitter._tickCallback (node.js:192:40)
Using ./
worked with require
but not for fs.readFileSync
. That's because for fs.readFileSync
, ./
translates into the cwd (in this case /home/user/
). And /home/user/files/somefile.txt
does not exist.
Note: In case you wish to use the already-mentioned algo for cases where you need to replace huge number of instances in the source string (e.g. new lines in long text) there is high probability you'll end up with StackOverflowException
because of the recursive call.

As others have said, some email programs will not read the css styles. If you already have a web email written up you can use the following tool from zurb to inline all of your styles:
http://zurb.com/ink/inliner.php
This comes in extremely handy when using templates like those mentioned above from mailchimp, campaign monitor, etc. as they, as you have found, will not work in some email programs. This tool leaves your style section for the mail programs that will read it and puts all the styles inline to get more universal readability in the format that you wanted.
The problem is that (as of 2016), for the password field, Firefox and Internet Explorer use the character "Black Circle" (?), which uses the Unicode code point 25CF
, but Chrome uses the character "Bullet" (•), which uses the Unicode code point 2022
.
As you can see, even in the StackOverflow font the two characters have different sizes.
The font you're using, "Lucida Sans Unicode", has an even greater disparity between the sizes of these two characters, leading to you noticing the difference.
The simple solution is to use a font in which both characters have similar sizes.
The fix could thus be to use a default font of the browser, which should render the characters in the password field just fine:
input[type="password"] {
font-family: caption;
}
This works for me in python 2.7
select some_date::DATE from some_table;
I like assylias' answer, however I would refactor it as follows:
Sub test()
Dim origNum As String
Dim creditOrDebit As String
origNum = "30062600006"
creditOrDebit = "D"
If creditOrDebit = "D" Then
If origNum = "006260006" Then
MsgBox "OK"
ElseIf origNum = "30062600006" Then
MsgBox "OK"
End If
End If
End Sub
This might save you some CPU cycles since if creditOrDebit
is <> "D"
there is no point in checking the value of origNum
.
I used the following procedure to test my theory that my procedure is faster:
Public Declare Function timeGetTime Lib "winmm.dll" () As Long
Sub DoTests2()
Dim startTime1 As Long
Dim endTime1 As Long
Dim startTime2 As Long
Dim endTime2 As Long
Dim i As Long
Dim msg As String
Const numberOfLoops As Long = 10000
Const origNum As String = "006260006"
Const creditOrDebit As String = "D"
startTime1 = timeGetTime
For i = 1 To numberOfLoops
If creditOrDebit = "D" Then
If origNum = "006260006" Then
' do something here
Debug.Print "OK"
ElseIf origNum = "30062600006" Then
' do something here
Debug.Print "OK"
End If
End If
Next i
endTime1 = timeGetTime
startTime2 = timeGetTime
For i = 1 To numberOfLoops
If (origNum = "006260006" Or origNum = "30062600006") And _
creditOrDebit = "D" Then
' do something here
Debug.Print "OK"
End If
Next i
endTime2 = timeGetTime
msg = "number of iterations: " & numberOfLoops & vbNewLine
msg = msg & "JP proc: " & Format$((endTime1 - startTime1), "#,###") & _
" ms" & vbNewLine
msg = msg & "assylias proc: " & Format$((endTime2 - startTime2), "#,###") & _
" ms"
MsgBox msg
End Sub
I must have a slow computer because 1,000,000 iterations took nowhere near ~200 ms as with assylias' test. I had to limit the iterations to 10,000 -- hey, I have other things to do :)
After running the above procedure 10 times, my procedure is faster only 20% of the time. However, when it is slower it is only superficially slower. As assylias pointed out, however, when creditOrDebit
is <>"D"
, my procedure is at least twice as fast. I was able to reasonably test it at 100 million iterations.
And that is why I refactored it - to short-circuit the logic so that origNum
doesn't need to be evaluated when creditOrDebit <> "D"
.
At this point, the rest depends on the OP's spreadsheet. If creditOrDebit
is likely to equal D, then use assylias' procedure, because it will usually run faster. But if creditOrDebit
has a wide range of possible values, and D
is not any more likely to be the target value, my procedure will leverage that to prevent needlessly evaluating the other variable.
I know that this question is accepted and has a bit of age but this might be helpful for some people who still find it relevant. Although the outcome is not a full RESTful API the API Builder mini lib for PHP allows you to easily transform MySQL databases into web accessible JSON APIs.
You can also simply convert a 2D array into hash using:
1.9.3p362 :005 > a= [[1,2],[3,4]]
=> [[1, 2], [3, 4]]
1.9.3p362 :006 > h = Hash[a]
=> {1=>2, 3=>4}
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.Current
which gets the synchronization context for the current thread.SynchronizationContext.Current
is populated depending on the environment you are in. TheGetAwaiter
method 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.Current
is 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.

. In fact, ReactJS provides an example of this in their documentation:
You should populate data with AJAX calls in the componentDidMount lifecycle method. This is so you can use setState to update your component when the data is retrieved.
componentDidMount() {
fetch("https://api.example.com/items")
.then(res => res.json())
.then(
(result) => {
this.setState({
isLoaded: true,
items: result.items
});
},
// Note: it's important to handle errors here
// instead of a catch() block so that we don't swallow
// exceptions from actual bugs in components.
(error) => {
this.setState({
isLoaded: true,
error
});
}
)
}
Decompress the JAR file and look for the manifest file (META-INF\MANIFEST.MF
). The manifest file of JAR file might contain a version number (but not always a version is specified).
You could try adding the following script code to implement this:
if(CompareDates(smallDate,largeDate,'-') == 0) {
alert('Selected date must be current date or previous date!');
return false;
}
function CompareDates(smallDate,largeDate,separator) {
var smallDateArr = Array();
var largeDateArr = Array();
smallDateArr = smallDate.split(separator);
largeDateArr = largeDate.split(separator);
var smallDt = smallDateArr[0];
var smallMt = smallDateArr[1];
var smallYr = smallDateArr[2];
var largeDt = largeDateArr[0];
var largeMt = largeDateArr[1];
var largeYr = largeDateArr[2];
if(smallYr>largeYr)
return 0;
else if(smallYr<=largeYr && smallMt>largeMt)
return 0;
else if(smallYr<=largeYr && smallMt==largeMt && smallDt>largeDt)
return 0;
else
return 1;
}
If your project is on a movie or TV, or anything that has a script, it looks like you definitely want to look at the work of Mark Everingham et al.. The software is available, as are the results on a Buffy episode.
If you are on windows and having problem either changing environment variables or mklink
because of insufficient privileges, an easy solution to your problem is to start git batch in another location.
Just right click on Git Bash.exe, click properties and change the "Start in" property to c:\my_configuration_files\
.
The blog article is mostly right, but not complete. To have a full understanding of what an odex file does, you have to understand a little about how application files (APK) work.
Applications are basically glorified ZIP archives. The java code is stored in a file called classes.dex and this file is parsed by the Dalvik JVM and a cache of the processed classes.dex file is stored in the phone's Dalvik cache.
An odex is basically a pre-processed version of an application's classes.dex that is execution-ready for Dalvik. When an application is odexed, the classes.dex is removed from the APK archive and it does not write anything to the Dalvik cache. An application that is not odexed ends up with 2 copies of the classes.dex file--the packaged one in the APK, and the processed one in the Dalvik cache. It also takes a little longer to launch the first time since Dalvik has to extract and process the classes.dex file.
If you are building a custom ROM, it's a really good idea to odex both your framework JAR files and the stock apps in order to maximize the internal storage space for user-installed apps. If you want to theme, then simply deodex -> apply your theme -> reodex -> release.
To actually deodex, use small and baksmali:
Looks like you'll need the path
module. (path.normalize
in particular)
var path = require("path"),
fs = require("fs");
fs.readFile(path.normalize(__dirname + "/../../foo.bar"));
In the future one would use left: unset;
for unsetting the value of left.
As of today 4 nov 2014 unset
is only supported in Firefox.
My guess is we'll be able to use it around year 2022 when IE 11 is properly phased out.
You want to create a "Dynamic Web Project". Follow the steps here: Spring MVC Tutorial with Eclipse and Tomcat.
Also, here is the Eclipse documentation for Dynamic Web Projects: http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.wst.webtools.doc.user/topics/ccwebprj.html
Just want to let you guys know, the accepted answer doesn't always work.
Here's an example it will fail.
if <href='/list'>
href = $('css_selector').attr('href')
"/list"
href = document.querySelector('css_selector').href
"http://localhost/list"
or you could append the href you got from jQuery to this
href = document.URL +$('css_selector').attr('href');
or jQuery way
href = $('css_selector').prop('href')
Finally, invoke it to change the browser current page's url
window.location.href = href
or pop it out using window.open(url)
Here's an example in JSFiddle.
If you want to execute that command, you should probably change:
PROCESS_NUM='ps -ef | grep "$1" | grep -v "grep" | wc -l'
to:
PROCESS_NUM=$(ps -ef | grep "$1" | grep -v "grep" | wc -l)
Why to invent the wheel?
There is a very popular NPM package, that let you do things like that easy.
var recursive = require("recursive-readdir");
recursive("some/path", function (err, files) {
// `files` is an array of file paths
console.log(files);
});
maybe you should try installing VC++ runtime as explained here.
There's a fairly good chance you're missing the correct VC++ runtime for the version of PHP you're running.
If you're running PHP 5.5.x you need to ensure the VC++11 runtime is installed:
http://www.microsoft.com/en-us/download/details.aspx?id=30679
Make sure you download and install the x86 version (vcredist_x86.exe), PHP on Windows isn't 64 bit yet.
If you're running PHP 5.4.x then you need to install the VC++9 runtime:
http://www.microsoft.com/en-us/download/details.aspx?id=5582
I have made a small demo of NumberPicker. This may not be perfect but you can use and modify the same.

{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView) findViewById(R.id.textView1);
Button b = (Button) findViewById(R.id.button11);
b.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
show();
}
});
}
@Override
public void onValueChange(NumberPicker picker, int oldVal, int newVal) {
Log.i("value is",""+newVal);
}
public void show()
{
final Dialog d = new Dialog(MainActivity.this);
d.setTitle("NumberPicker");
d.setContentView(R.layout.dialog);
Button b1 = (Button) d.findViewById(R.id.button1);
Button b2 = (Button) d.findViewById(R.id.button2);
final NumberPicker np = (NumberPicker) d.findViewById(R.id.numberPicker1);
np.setMaxValue(100);
np.setMinValue(0);
np.setWrapSelectorWheel(false);
np.setOnValueChangedListener(this);
b1.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
tv.setText(String.valueOf(np.getValue()));
d.dismiss();
}
});
b2.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
d.dismiss();
}
});
d.show();
}

exit
is a helper for the interactive shell - sys.exit
is intended for use in programs.
The
site
module (which is imported automatically during startup, except if the-S
command-line option is given) adds several constants to the built-in namespace (e.g.exit
). They are useful for the interactive interpreter shell and should not be used in programs.
Technically, they do mostly the same: raising SystemExit
. sys.exit
does so in sysmodule.c:
static PyObject *
sys_exit(PyObject *self, PyObject *args)
{
PyObject *exit_code = 0;
if (!PyArg_UnpackTuple(args, "exit", 0, 1, &exit_code))
return NULL;
/* Raise SystemExit so callers may catch it or clean up. */
PyErr_SetObject(PyExc_SystemExit, exit_code);
return NULL;
}
While exit
is defined in site.py and _sitebuiltins.py, respectively.
class Quitter(object):
def __init__(self, name):
self.name = name
def __repr__(self):
return 'Use %s() or %s to exit' % (self.name, eof)
def __call__(self, code=None):
# Shells like IDLE catch the SystemExit, but listen when their
# stdin wrapper is closed.
try:
sys.stdin.close()
except:
pass
raise SystemExit(code)
__builtin__.quit = Quitter('quit')
__builtin__.exit = Quitter('exit')
Note that there is a third exit option, namely os._exit, which exits without calling cleanup handlers, flushing stdio buffers, etc. (and which should normally only be used in the child process after a fork()
).
To customize markers, you can do it from this online tool: https://materialdesignicons.com/
In your case, you want the map-marker which is available here: https://materialdesignicons.com/icon/map-marker and which you can customize online.
If you simply want to change the default Red color to Blue, you can load this icon: http://maps.google.com/mapfiles/ms/icons/blue-dot.png
It's been mentioned in this thread: https://stackoverflow.com/a/32651327/6381715

(For those who read all answers). My case was simply the fact that I created a SQL expression using the format Forms!Table!Control. That format is Ok within a query, but DAO doesn't recognize it. I'm surprised that nobody commented this.
This doesn't work:
Dim rs As DAO.Recordset, strSQL As String
strSQL = "SELECT * FROM Table1 WHERE Name = Forms!Table!Control;"
Set rs = CurrentDb.OpenRecordset(strSQL)
This is Ok:
Dim rs As DAO.Recordset, strSQL, val As String
val = Forms!Table!Control
strSQL = "SELECT * FROM Table1 WHERE Name = '" & val & "';"
Set rs = CurrentDb.OpenRecordset(strSQL)
I was lead here in my Google searching. In a show of good faith I have included what I pieced together from parts of this code and other code I've gathered along the way.

Both OpenJDK and Oracle JDK are created and maintained currently by Oracle only.
OpenJDK and Oracle JDK are implementations of the same Java specification passed the TCK (Java Technology Certification Kit).
Most of the vendors of JDK are written on top of OpenJDK by doing a few tweaks to [mostly to replace licensed proprietary parts / replace with more high-performance items that only work on specific OS] components without breaking the TCK compatibility.
Many vendors implemented the Java specification and got TCK passed. For example, IBM J9, Azul Zulu, Azul Zing, and Oracle JDK.
Almost every existing JDK is derived from OpenJDK.
As suggested by many, licensing is a change between JDKs.
Starting with JDK 11 accessing the long time support Oracle JDK/Java SE will now require a commercial license. You should now pay attention to which JDK you're installing as Oracle JDK without subscription could stop working. source
This was my own attempt, but I'll use the answer by annakata as it seems much cleaner:
function AddUrlParameter(sourceUrl, parameterName, parameterValue, replaceDuplicates)
{
if ((sourceUrl == null) || (sourceUrl.length == 0)) sourceUrl = document.location.href;
var urlParts = sourceUrl.split("?");
var newQueryString = "";
if (urlParts.length > 1)
{
var parameters = urlParts[1].split("&");
for (var i=0; (i < parameters.length); i++)
{
var parameterParts = parameters[i].split("=");
if (!(replaceDuplicates && parameterParts[0] == parameterName))
{
if (newQueryString == "")
newQueryString = "?";
else
newQueryString += "&";
newQueryString += parameterParts[0] + "=" + parameterParts[1];
}
}
}
if (newQueryString == "")
newQueryString = "?";
else
newQueryString += "&";
newQueryString += parameterName + "=" + parameterValue;
return urlParts[0] + newQueryString;
}
Also, I found this jQuery plugin from another post on stackoverflow, and if you need more flexibility you could use that: http://plugins.jquery.com/project/query-object
I would think the code would be (haven't tested):
return $.query.parse(sourceUrl).set(parameterName, parameterValue).toString();
Powder's comment may go undetected like I missed it so many times,. So with the hope of making it more visible, I will re-iterate his point.
Sometimes using image = array(img).reshape(a,b,c,d)
will reshape alright but from experience, my kernel crashes every time I try to use the new dimension in an operation. The safest to use is
np.expand_dims(img, axis=0)
It works perfect every time. I just can't explain why. This link has a great explanation and examples regarding its usage.
Trevor Howard has some UIImage categories that handle resize quite nicely. If nothing else you can use the code as examples.
Note: As of iOS 5.1, this answer maybe invalid. See comment below.
It would be better to implement a synchronization mechanism. The easiest is to write a file after the first file is complete. So you have a sentinel file.
So the external programs looks for the sentinel file to exist. When it does it knows that it can safely use the data in the real file.
Another way to do this, which is similar to how some browsers do it when downloading files, is to have the file named base-name_part until the file is completely downloaded and then at the end rename the file to base-name. This way the external program can't "see" the file until it is complete. This way wouldn't require rewrite of the external program. Which might make it best for this situation.
Tried deleting IISExpress folder, changed port , restart VS and PC but it didn't work. However it worked after killing iisexpress.exe service in services.
You can turn the axes off by following the advice in Veedrac's comment (linking to here) with one small modification.
Rather than using plt.axis('off')
you should use ax.axis('off')
where ax
is a matplotlib.axes
object. To do this for your code you simple need to add axarr[0,0].axis('off')
and so on for each of your subplots.
The code below shows the result (I've removed the prune_matrix
part because I don't have access to that function, in the future please submit fully working code.)
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import matplotlib.cm as cm
img = mpimg.imread("stewie.jpg")
f, axarr = plt.subplots(2, 2)
axarr[0,0].imshow(img, cmap = cm.Greys_r)
axarr[0,0].set_title("Rank = 512")
axarr[0,0].axis('off')
axarr[0,1].imshow(img, cmap = cm.Greys_r)
axarr[0,1].set_title("Rank = %s" % 128)
axarr[0,1].axis('off')
axarr[1,0].imshow(img, cmap = cm.Greys_r)
axarr[1,0].set_title("Rank = %s" % 32)
axarr[1,0].axis('off')
axarr[1,1].imshow(img, cmap = cm.Greys_r)
axarr[1,1].set_title("Rank = %s" % 16)
axarr[1,1].axis('off')
plt.show()
Note: To turn off only the x or y axis you can use set_visible()
e.g.:
axarr[0,0].xaxis.set_visible(False) # Hide only x axis
Something as simple as [a-z]+
, or perhaps [\S]+
, or even [a-zA-Z]+
?

And add to the first line of code:
from silence_tensorflow import silence_tensorflow

A rect
can't contain a text
element. Instead transform a g
element with the location of text and rectangle, then append both the rectangle and the text to it:
var bar = chart.selectAll("g")
.data(data)
.enter().append("g")
.attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });
bar.append("rect")
.attr("width", x)
.attr("height", barHeight - 1);
bar.append("text")
.attr("x", function(d) { return x(d) - 3; })
.attr("y", barHeight / 2)
.attr("dy", ".35em")
.text(function(d) { return d; });

Multi-line labels are also a little tricky, you might want to check out this wrap function.
The servlet container's implementation of HttpServlet.service()

While the code to create a custom Attribute is fairly simple, it's very important that you understand what attributes are:
Attributes are metadata compiled into your program. Attributes themselves do not add any functionality to a class, property or module - just data. However, using reflection, one can leverage those attributes in order to create functionality.
So, for instance, let's look at the Validation Application Block, from Microsoft's Enterprise Library. If you look at a code example, you'll see:
/// <summary>
/// blah blah code.
/// </summary>
[DataMember]
[StringLengthValidator(8, RangeBoundaryType.Inclusive, 8, RangeBoundaryType.Inclusive, MessageTemplate = "\"{1}\" must always have \"{4}\" characters.")]
public string Code { get; set; }
From the snippet above, one might guess that the code will always be validated, whenever changed, accordingly to the rules of the Validator (in the example, have at least 8 characters and at most 8 characters). But the truth is that the Attribute does nothing; as mentioned previously, it only adds metadata to the property.
However, the Enterprise Library has a Validation.Validate
method that will look into your object, and for each property, it'll check if the contents violate the rule informed by the attribute.
So, that's how you should think about attributes -- a way to add data to your code that might be later used by other methods/classes/etc.
I couldn't get the above examples to work. I simply wanted to trigger a refresh of certain modified div areas when coming back to the page via the back button. The trick I used was to set a hidden input field (called a "dirty bit") to 1 as soon as the div areas changed from the original. The hidden input field actually retains its value when I click back, so onload I can check for this bit. If it's set, I refresh the page (or just refresh the divs). On the original load, however, the bit is not set, so I don't waste time loading the page twice.
<input type='hidden' id='dirty'>
<script>
$(document).ready(function() {
if ($('#dirty').val()) {
// ... reload the page or specific divs only
}
// when something modifies a div that needs to be refreshed, set dirty=1
$('#dirty').val('1');
});
</script>
And it would trigger properly whenever I clicked the back button.
You can call the super class's constructor like this
class A(object):
def __init__(self, number):
print "parent", number
class B(A):
def __init__(self):
super(B, self).__init__(5)
b = B()
NOTE:
This will work only when the parent class inherits object
You have several options to set up variables from outside your makefile:
From environment - each environment variable is transformed into a makefile variable with the same name and value.
You may also want to set -e
option (aka --environments-override
) on, and your environment variables will override assignments made into makefile (unless these assignments themselves use the override
directive . However, it's not recommended, and it's much better and flexible to use ?=
assignment (the conditional variable assignment operator, it only has an effect if the variable is not yet defined):
FOO?=default_value_if_not_set_in_environment
Note that certain variables are not inherited from environment:
MAKE
is gotten from name of the scriptSHELL
is either set within a makefile, or defaults to /bin/sh
(rationale: commands are specified within the makefile, and they're shell-specific).From command line - make
can take variable assignments as part of his command line, mingled with targets:
make target FOO=bar
But then all assignments to FOO
variable within the makefile will be ignored unless you use the override
directive in assignment. (The effect is the same as with -e
option for environment variables).
Exporting from the parent Make - if you call Make from a Makefile, you usually shouldn't explicitly write variable assignments like this:
# Don't do this!
target:
$(MAKE) -C target CC=$(CC) CFLAGS=$(CFLAGS)
Instead, better solution might be to export these variables. Exporting a variable makes it into the environment of every shell invocation, and Make calls from these commands pick these environment variable as specified above.
# Do like this
CFLAGS=-g
export CFLAGS
target:
$(MAKE) -C target
You can also export all variables by using export
without arguments.
In Excel for Mac 2016 at least,if you place the labels in any spot on the graph and are looking to move them anywhere else (in this case above the bars), select:
Chart Design->Add Chart Element->Data Labels -> More Data Label Options
then you can grab each individual label and pull it where you would like it.
Instead of using $_POST, use $_REQUEST:
HTML:
<form action="" method="post">
<input type="text" name="firstname">
<input type="submit" name="submit" value="Submit">
</form>
PHP:
if(isset($_REQUEST['submit'])){
$test = $_REQUEST['firstname'];
echo $test;
}
Just want to add that apparently adding a space at the end of the string will use UTC for creation.

Edit: This is not a recommended solution, just an alternative answer. Please do not use this approach since it is very unclear what is happening. There are a number of ways someone could refactor this accidentally causing a bug.
These days, there are quite a few modules available for this. I recently wrote a module to do this, because I wasn't satisfied with the numerous diffing modules I found. Its called odiff
: https://github.com/Tixit/odiff . I also listed a bunch of the most popular modules and why they weren't acceptable in the readme of odiff
, which you could take a look through if odiff
doesn't have the properties you want. Here's an example:
var a = [{a:1,b:2,c:3}, {x:1,y: 2, z:3}, {w:9,q:8,r:7}]
var b = [{a:1,b:2,c:3},{t:4,y:5,u:6},{x:1,y:'3',z:3},{t:9,y:9,u:9},{w:9,q:8,r:7}]
var diffs = odiff(a,b)
/* diffs now contains:
[{type: 'add', path:[], index: 2, vals: [{t:9,y:9,u:9}]},
{type: 'set', path:[1,'y'], val: '3'},
{type: 'add', path:[], index: 1, vals: [{t:4,y:5,u:6}]}
]
*/
Your function is probably in a different namespace than the one you're calling it from.

This command will start recording your device’s screen using the default settings and save the resulting video to a file at /sdcard/example.mp4 file on your device.
When you’re done recording, press Ctrl+C in the Command Prompt window to stop the screen recording. You can then find the screen recording file at the location you specified. Note that the screen recording is saved to your device’s internal storage, not to your computer.
The default settings are to use your device’s standard screen resolution, encode the video at a bitrate of 4Mbps, and set the maximum screen recording time to 180 seconds. For more information about the command-line options you can use, run the following command:
adb shell screenrecord --help
This works without rooting the device. Hope this helps.
Another option is to set your child div to display: inline-block;

Try using the html() function.
$('#<%=Label1.ClientID%>').html();
You're also missing the # to make it an ID you're searching for. Without the #, it's looking for a tag type.
We use the node-deep-equal project which implements the same deep-equal comparison as nodejs
A google serach for deep-equal on npm will show you many alternatives
Are you looking for a Windows API?
Just use SHGetFolderPath function with CSIDL_INTERNET_CACHE flag or SHGetKnownFolderPath with FOLDERID_InternetCache flag to get the exact location. This way you don't have to worry about the OS. The former function works in Windows XP. The latter one works in Windows Vista+.
No. We cannot alter the constraint, only thing we can do is drop and recreate it
ALTER TABLE [TABLENAME] DROP CONSTRAINT [CONSTRAINTNAME]
Foreign Key Constraint
Alter Table Table1 Add Constraint [CONSTRAINTNAME] Foreign Key (Column) References Table2 (Column) On Update Cascade On Delete Cascade
Primary Key constraint
Alter Table Table add constraint [Primary Key] Primary key(Column1,Column2,.....)
When calling just git tag <TAGNAME>
without any additional parameters, Git will create a new tag from your current HEAD (i.e. the HEAD of your current branch). When adding additional commits into this branch, the branch HEAD will keep up with those new commits, while the tag always refers to the same commit.
When calling git tag <TAGNAME> <COMMIT>
you can even specify which commit to use for creating the tag.
Regardless, a tag is still simply a "pointer" to a certain commit (not a branch).
If you use XCode
5 you should do it in a different way.
UIViewController
in UIStoryboard
Identity Inspector
on the right top paneUse Storyboard ID
checkboxStoryboard ID
fieldThen write your code.
// Override point for customization after application launch.
if (<your implementation>) {
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main"
bundle: nil];
YourViewController *yourController = (YourViewController *)[mainStoryboard
instantiateViewControllerWithIdentifier:@"YourViewControllerID"];
self.window.rootViewController = yourController;
}
return YES;
In addition to values_list
as Daniel mentions you can also use only
(or defer
for the opposite effect) to get a queryset of objects only having their id and specified fields:
Employees.objects.only('eng_name')
This will run a single query:
SELECT id, eng_name FROM employees
You can simply detect the current local format and can get the date in your format, for example:
::for 30.10.2016 dd.MM.yyyy
if %date:~2,1%==. set d=%date:~-4%%date:~3,2%%date:~,2%
::for 10/30/2016 MM/dd/yyyy
if %date:~2,1%==/ set d=%date:~-4%%date:~,2%%date:~3,2%
::for 2016-10-30 yyyy-MM-dd
if %date:~4,1%==- set d=%date:~,4%%date:~5,2%%date:~-2%
::variable %d% have now value: 2016103 (yyyyMMdd)
set t=%time::=%
set t=%t:,=%
::variable %t% have now time without delimiters
cp source.log %d%_%t%.log
DateTime.Now will not work, use DateTime.Today instead.
Similar to the other examples, but using html sizing, I use:
<img src="image1.png" width="425"/> <img src="image2.png" width="425"/>
Here is an example
<img src="https://openclipart.org/image/2400px/svg_to_png/28580/kablam-Number-Animals-1.png" width="200"/> <img src="https://openclipart.org/download/71101/two.svg" width="300"/>
I tested this using Remarkable.
you can do this easily by using jquery using .css property... try this one: http://api.jquery.com/css/
You might find it better to use a 3rd party program to enter the queries into Access such as WinSQL I think from memory WinSQL supports multiple queries via it's batch feature.
I ultimately found it easier to just write a program in perl to do bulk INSERTS into an Access via ODBC. You could use vbscript or any language that supports ODBC though.
You can then do anything you like and have your own complicated logic to handle the importing.
Although some of them are correct, I've found quite confusing the previous responses. At the same time, the OP asked for a solution without setting a custom header or using beforeSend
, so I've being looking for a clearer explanation. I hope my conclusions provide some light to others.
The code
jQuery.ajax({
....
accepts: "application/json; charset=utf-8",
....
});
doesn't work because accepts
must be a PlainObject
(not a String
) according to the jQuery doc (http://api.jquery.com/jquery.ajax/). Specifically, jQuery expect zero or more key-value pairs relating each dataType
with the accepted MIME type for them. So what I've finally using is:
jQuery.ajax({
....
dataType: 'json',
accepts: {
json: 'application/json'
},
....
});

I nearly used everything in that article to create the SQLite database for my own C# Application.
Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.
After you added the reference, refer to the dll from your code using the following line on top of your class:
using System.Data.SQLite;
You can find the dll's here:
You can find the NuGet way here:
Up next is the create script. Creating a database file:
SQLiteConnection.CreateFile("MyDatabase.sqlite");
SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();
string sql = "create table highscores (name varchar(20), score int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
sql = "insert into highscores (name, score) values ('Me', 9001)";
command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
m_dbConnection.Close();
After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.
Example on how to use transactions:
using (TransactionScope tran = new TransactionScope())
{
//Insert create script here.
//Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
tran.Complete();
}
Simple printf() function from O'Reilly's Python Cookbook.
import sys
def printf(format, *args):
sys.stdout.write(format % args)
Example output:
i = 7
pi = 3.14159265359
printf("hi there, i=%d, pi=%.2f\n", i, pi)
# hi there, i=7, pi=3.14
SELECT * from employees
WHERE NOT EXISTS (SELECT name FROM eotm_dyn)
Never returns any records unless eotm_dyn
is empty. You need to some kind of criteria on SELECT name FROM eotm_dyn
like
SELECT * from employees
WHERE NOT EXISTS (
SELECT name FROM eotm_dyn WHERE eotm_dyn.employeeid = employees.employeeid
)
assuming that the two tables are linked by a foreign key relationship. At this point you could use a variety of other options including a LEFT JOIN. The optimizer will typically handle them the same in most cases, however.
Why not using attribute "disabled" in css. This must works on all browsers.

The proper Swift operator is is
:
if touch.view is UIPickerView {
// touch.view is of type UIPickerView
}
Of course, if you also need to assign the view to a new constant, then the if let ... as? ...
syntax is your boy, as Kevin mentioned. But if you don't need the value and only need to check the type, then you should use the is
operator.
Approach: 1
Given original string
format: 2019/03/04 00:08:48
you can use
updated_df = df['timestamp'].astype('datetime64[ns]')
The result will be in this datetime
format: 2019-03-04 00:08:48
Approach: 2
updated_df = df.astype({'timestamp':'datetime64[ns]'})
Similar to @Wolfram J's answer, here is a method to encrypt your private key with a passphrase:
gpg --output - --armor --export $KEYID | \
gpg --output private_key.asc --armor --symmetric --cipher-algo AES256
And a corresponding method to decrypt:
gpg private_key.asc
I found this function on a blog
ggplotRegression <- function (fit) {
`require(ggplot2)
ggplot(fit$model, aes_string(x = names(fit$model)[2], y = names(fit$model)[1])) +
geom_point() +
stat_smooth(method = "lm", col = "red") +
labs(title = paste("Adj R2 = ",signif(summary(fit)$adj.r.squared, 5),
"Intercept =",signif(fit$coef[[1]],5 ),
" Slope =",signif(fit$coef[[2]], 5),
" P =",signif(summary(fit)$coef[2,4], 5)))
}`
once you loaded the function you could simply
ggplotRegression(fit)
you can also go for ggplotregression( y ~ x + z + Q, data)
Hope this helps.
Using the luxon.js library, same can be achieved using startOf and endOf methods by passing the 'day' as parameter
var DateTime = luxon.DateTime;
DateTime.local().startOf('day').toUTC().toISO(); //2017-11-16T18:30:00.000Z
DateTime.local().endOf('day').toUTC().toISO(); //2017-11-17T18:29:59.999Z
DateTime.fromISO(new Date().toISOString()).startOf('day').toUTC().toISO(); //2017-11-16T18:30:00.000Z
remove .toUTC() if you need only the local time

If you've ever been saved by an Emacs backup file, you
probably want more of them, not less of them. It is annoying
that they go in the same directory as the file you're editing,
but that is easy to change. You can make all backup files go
into a directory by putting something like the following in your
.emacs
.
(setq backup-directory-alist `(("." . "~/.saves")))
There are a number of arcane details associated with how Emacs might create your backup files. Should it rename the original and write out the edited buffer? What if the original is linked? In general, the safest but slowest bet is to always make backups by copying.
(setq backup-by-copying t)
If that's too slow for some reason you might also have a look at
backup-by-copying-when-linked
.
Since your backups are all in their own place now, you might want
more of them, rather than less of them. Have a look at the Emacs
documentation for these variables (with C-h v
).
(setq delete-old-versions t
kept-new-versions 6
kept-old-versions 2
version-control t)
Finally, if you absolutely must have no backup files:
(setq make-backup-files nil)
It makes me sick to think of it though.
ls=['hello','world']
ls.append('python')
['hello', 'world', 'python']
or (use insert
function where you can use index position in list)
ls.insert(0,'python')
print(ls)
['python', 'hello', 'world']
The Objective-C language level synchronization uses the mutex, just like NSLock
does. Semantically there are some small technical differences, but it is basically correct to think of them as two separate interfaces implemented on top of a common (more primitive) entity.
In particular with a NSLock
you have an explicit lock whereas with @synchronized
you have an implicit lock associated with the object you are using to synchronize. The benefit of the language level locking is the compiler understands it so it can deal with scoping issues, but mechanically they behave basically the same.
You can think of @synchronized
as a compiler rewrite:
- (NSString *)myString {
@synchronized(self) {
return [[myString retain] autorelease];
}
}
is transformed into:
- (NSString *)myString {
NSString *retval = nil;
pthread_mutex_t *self_mutex = LOOK_UP_MUTEX(self);
pthread_mutex_lock(self_mutex);
retval = [[myString retain] autorelease];
pthread_mutex_unlock(self_mutex);
return retval;
}
That is not exactly correct because the actual transform is more complex and uses recursive locks, but it should get the point across.
Unicode is not an encoding - to quote Kumar McMillan:
If ASCII, UTF-8, and other byte strings are "text" ...
...then Unicode is "text-ness";
it is the abstract form of text
Have a read of McMillan's Unicode In Python, Completely Demystified talk from PyCon 2008, it explains things a lot better than most of the related answers on Stack Overflow.
My problem was a misspelled component name inside the component.ts
.
The import statement didn't show an error but the declaration did, which misled me.
I really like the description and the example from http://python-3-patterns-idioms-test.readthedocs.io/en/latest/Visitor.html.
The assumption is that you have a primary class hierarchy that is fixed; perhaps it’s from another vendor and you can’t make changes to that hierarchy. However, your intent is that you’d like to add new polymorphic methods to that hierarchy, which means that normally you’d have to add something to the base class interface. So the dilemma is that you need to add methods to the base class, but you can’t touch the base class. How do you get around this?
The design pattern that solves this kind of problem is called a “visitor” (the final one in the Design Patterns book), and it builds on the double dispatching scheme shown in the last section.
The visitor pattern allows you to extend the interface of the primary type by creating a separate class hierarchy of type Visitor to virtualize the operations performed upon the primary type. The objects of the primary type simply “accept” the visitor, then call the visitor’s dynamically-bound member function.
So simple you can use case statement here.
CASE WHEN ISSUE_DIVISION = ISSUE_DIVISION_2 THEN
CASE WHEN ISSUE_DIVISION is null then "Null Value found" //give your option
Else 1 End
ELSE 0 END As Issue_Division_Result
The other solutions didn't work for me. Maybe the old DOCTYPE in the project I am working on prevents HTML5 options.
My solution:
<form id="form_1" action="result.php" method="post"
onsubmit="sendForm(this.id);return false">
<input type="hidden" name="something" value="1">
</form>
js:
function sendForm(form_id){
var form = $('#'+form_id);
$.ajax({
type: 'POST',
url: $(form).attr('action'),
data: $(form).serialize(),
success: function(result) {
console.log(result)
}
});
}
Multiple statements are to be separated by a new line:

ElseIf SkyIsRed Then
StopAttack

ElseIf SkyIsYellow Then
If Sunset Then
Sleep
ElseIf Sunrise or IsMorning Then

The following works for me in case you need last two tags (for example, in order to generate change log between current tag and the previous tag). I've tested it only in situation where the latest tag was the HEAD
.
PreviousAndCurrentGitTag=`git describe --tags \`git rev-list --tags --abbrev=0 --max-count=2\` --abbrev=0`
PreviousGitTag=`echo $PreviousAndCurrentGitTag | cut -f 2 -d ' '`
CurrentGitTag=`echo $PreviousAndCurrentGitTag | cut -f 1 -d ' '`
GitLog=`git log ${PreviousGitTag}..${CurrentGitTag} --pretty=oneline | sed "s_.\{41\}\(.*\)_; \1_"`
It suits my needs, but as I'm no git wizard, I'm sure it could be further improved. I also suspect it will break in case the commit history moves forward. I'm just sharing in case it helps someone.
In Django 1.10 (possibly earlier as well) you can do it as follows.
Model:
class Todo(models.Model):
todo_name = models.CharField(max_length=200)
todo_description = models.CharField(max_length=200, default="")
todo_created = models.DateTimeField('date created')
todo_completed = models.BooleanField(default=False)
def __str__(self):
return self.todo_name
Form:
class TodoUpdateForm(forms.ModelForm):
class Meta:
model = Todo
exclude = ('todo_created','todo_completed')
Template:
<form action="" method="post">{% csrf_token %}
{{ form.non_field_errors }}
<div class="fieldWrapper">
{{ form.todo_name.errors }}
<label for="{{ form.name.id_for_label }}">Name:</label>
{{ form.todo_name }}
</div>
<div class="fieldWrapper">
{{ form.todo_description.errors }}
<label for="{{ form.todo_description.id_for_label }}">Description</label>
{{ form.todo_description }}
</div>
<input type="submit" value="Update" />
</form>
var delete_id = _(savedViews).where({ description : view }).get('0.id')
Turns out it is possible to enter a host name directly into the playbook, so running the playbook with hosts: imac-2.local
will work fine. But it's kind of clunky.
A better solution might be defining the playbook's hosts using a variable, then passing in a specific host address via --extra-vars
:
# file: user.yml (playbook)
---
- hosts: '{{ target }}'
user: ...
Running the playbook:
ansible-playbook user.yml --extra-vars "target=imac-2.local"
If {{ target }}
isn't defined, the playbook does nothing. A group from the hosts file can also be passed through if need be. Overall, this seems like a much safer way to construct a potentially destructive playbook.
Playbook targeting a single host:
$ ansible-playbook user.yml --extra-vars "target=imac-2.local" --list-hosts
playbook: user.yml
play #1 (imac-2.local): host count=1
imac-2.local
Playbook with a group of hosts:
$ ansible-playbook user.yml --extra-vars "target=office" --list-hosts
playbook: user.yml
play #1 (office): host count=3
imac-1.local
imac-2.local
imac-3.local
Forgetting to define hosts is safe!
$ ansible-playbook user.yml --list-hosts
playbook: user.yml
play #1 ({{target}}): host count=0
Most modern desktop browsers such as Chrome, Mozilla and Internet Explorer support images encoded as data URL. But there are problems displaying data URLs in some mobile browsers: Android Stock Browser and Dolphin Browser won't display embedded JPEGs.
I reccomend you to use the following tools for online base64 encoding/decoding:
Check the "Format as Data URL" option to format as a Data URL.
By design the body content in ASP.NET Web API is treated as forward-only stream that can be read only once.
The first read in your case is being done when Web API is binding your model, after that the Request.Content
will not return anything.
You can remove the contact
from your action parameters, get the content and deserialize it manually into object (for example with Json.NET):
[HttpPut]
public HttpResponseMessage Put(int accountId)
{
HttpContent requestContent = Request.Content;
string jsonContent = requestContent.ReadAsStringAsync().Result;
CONTACT contact = JsonConvert.DeserializeObject<CONTACT>(jsonContent);
...
}
That should do the trick (assuming that accountId
is URL parameter so it will not be treated as content read).

Arrays (called list
in python) use the []
notation. {}
is for dict
(also called hash tables, associated arrays, etc in other languages) so you won't have 'append' for a dict.
If you actually want an array (list), use:
array = []
array.append(valueToBeInserted)
DISTINCT
removes rows if all selected values are equal. Apparently, you have entries with the same p.id
but with different pl.nm
(or pl.val
or pl.txt_val
). The answer to your question depends on which one of these values you want to show in the one row with your p.id
(the first? the smallest? any?).

If you are using the default cursor, a MySQLdb.cursors.Cursor
, the entire result set will be stored on the client side (i.e. in a Python list) by the time the cursor.execute()
is completed.
Therefore, even if you use
for row in cursor:
you will not be getting any reduction in memory footprint. The entire result set has already been stored in a list (See self._rows
in MySQLdb/cursors.py).
However, if you use an SSCursor or SSDictCursor:
import MySQLdb
import MySQLdb.cursors as cursors
conn = MySQLdb.connect(..., cursorclass=cursors.SSCursor)
then the result set is stored in the server, mysqld. Now you can write
cursor = conn.cursor()
cursor.execute('SELECT * FROM HUGETABLE')
for row in cursor:
print(row)
and the rows will be fetched one-by-one from the server, thus not requiring Python to build a huge list of tuples first, and thus saving on memory.
Otherwise, as others have already stated, cursor.fetchall()
and list(cursor)
are essentially the same.

I've been using Crittercism for my Android and iOS apps -- heard about them on techcrunch. Pretty happy with them so far!
For C++ :
I just faced the same issue and I think it is worth mentioning a problem comes up when one use both __stdcall
(or WINAPI
) and extern "C"
:
As you know extern "C"
removes the decoration so that instead of :
__declspec(dllexport) int Test(void) --> dumpbin : ?Test@@YaHXZ
you obtain a symbol name undecorated:
extern "C" __declspec(dllexport) int Test(void) --> dumpbin : Test
However the _stdcall
( = macro WINAPI, that changes the calling convention) also decorates names so that if we use both we obtain :
extern "C" __declspec(dllexport) int WINAPI Test(void) --> dumpbin : _Test@0
and the benefit of extern "C"
is lost because the symbol is decorated (with _ @bytes)
Note that this only occurs for x86 architecture because the
__stdcall
convention is ignored on x64 (msdn : on x64 architectures, by convention, arguments are passed in registers when possible, and subsequent arguments are passed on the stack.).
This is particularly tricky if you are targeting both x86 and x64 platforms.
Two solutions
Use a definition file. But this forces you to maintain the state of the def file.
the simplest way : define the macro (see msdn) :
#define EXPORT comment(linker, "/EXPORT:" __FUNCTION__ "=" __FUNCDNAME__)
and then include the following pragma in the function body:
#pragma EXPORT
Full Example :
int WINAPI Test(void)
{
#pragma EXPORT
return 1;
}
This will export the function undecorated for both x86 and x64 targets while preserving the __stdcall
convention for x86. The __declspec(dllexport)
is not required in this case.
Just set css property of container div 'pointer-events' as none i.e. 'pointer-events:none;'

In Kotlin you can do as
val videoView = findViewById<VideoView>(R.id.videoView)
// If url is from raw
/* val url = "android.resource://" + packageName
.toString() + "/" + R.raw.video*/
// If url is from network
val url = "http://www.servername.com/projects/projectname/videos/1361439400.mp4"
val video =
Uri.parse(url)
videoView.setVideoURI(video)
videoView.setOnPreparedListener{
videoView.start()
}

AFAIK there is no way to use push/pop semantics for this option.
I had this problem and the issue was that I had the package loaded in another R instance. Simply closing all R instances and installing on a fresh instance allowed for the package to be installed.
Generally, you can also install if every remaining instance has never loaded the package as well (even if it installed an old version).
A proper REST API should have below components in response
The main purpose of ResponseEntity was to provide the option 3, rest options could be achieved without ResponseEntity.
So if you want to provide the location of resource then using ResponseEntity would be better else it can be avoided.
Consider an example where a API is modified to provide all the options mentioned
// Step 1 - Without any options provided
@RequestMapping(value="/{id}", method=RequestMethod.GET)
public @ResponseBody Spittle spittleById(@PathVariable long id) {
return spittleRepository.findOne(id);
}
// Step 2- We need to handle exception scenarios, as step 1 only caters happy path.
@ExceptionHandler(SpittleNotFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
public Error spittleNotFound(SpittleNotFoundException e) {
long spittleId = e.getSpittleId();
return new Error(4, "Spittle [" + spittleId + "] not found");
}
// Step 3 - Now we will alter the service method, **if you want to provide location**
@RequestMapping(
method=RequestMethod.POST
consumes="application/json")
public ResponseEntity<Spittle> saveSpittle(

As far as i know, writing multiple matches is logical AND operation; so what your rule means is if the destination port is "59100" AND "3000" then reject connection with tcp-reset; Workaround is using -mport option. Look out for the man page.
<%= link_to root_path do %><%= image_tag("Search.png",:alt=>'Vivek',:title=>'Vivek',:class=>'dock-item')%><%= content_tag(:span, "Search").html_safe%><% end %>
If you want to get one element by row index and column name, you can do it just like df['b'][0]
. It is as simple as you can imagine.
Or you can use df.ix[0,'b']
- mixed usage of index and label.
Note: Since v0.20, ix
has been deprecated in favour of loc
/ iloc
.
In Visual Studio 2012 all I had to do was enter:
(localdb)\v11.0
Visual Studio 2015 and Visual Studio 2017 changed to:
(localdb)\MSSQLLocalDB
as the server name when adding a Microsoft SQL Server Data
source in:
View/Server Explorer/(Right click) Data Connections/Add Connection
and then the database names were populated. I didn't need to do all the other steps in the accepted answer, although it would be nice if the server name was available automatically in the server name combo box.
You can also browse the LocalDB database names available on your machine using:
View/SQL Server Object Explorer.
I had this problem recently and I figured it was because I had deleted some files that I did not need anymore. The problem is that git does not know that the files have been deleted and it sees that the server still has it. (server = origin)
So I ran
git rm $(git ls-files --deleted)
And then ran a commit and push.
That solved the issue.
I used:
var save_and_add = function(){
tinyMCE.triggerSave();
$('.new_multi_text_block_item').submit();
};
This is all you need to do.
I recommend using the altex-image-downloader library, which makes it easy to download images:
AltexImageDownloader.writeToDisk(context, Imageurl, "IMAGES");
Add dependency in app build gradle:
implementation 'com.artjimlop:altex-image-downloader:0.0.4'
If you want to see the array as an array, you can say
alert(JSON.stringify(aCustomers));
instead of all those document.write
s.
However, if you want to display them cleanly, one per line, in your popup, do this:
alert(aCustomers.join("\n"));
From ?read.table
: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.
So, perhaps your data file isn't clean. Being more specific will help the data import:
d = read.table("foobar.txt",
sep="\t",
col.names=c("id", "name"),
fill=FALSE,
strip.white=TRUE)
will specify exact columns and fill=FALSE
will force a two column data frame.
Creating a builder launcher is an issue since 2 projects cannot have the same external tool build name. Each name has to be unique. I am currently facing this issue to automate my build and copy the JAR to an external location.

As mentioned in JavaDoc (https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/CountDownLatch.html), CountDownLatch is a synchronization aid, introduced in Java 5. Here the synchronization does not mean restricting access to a critical section. But rather sequencing actions of different threads. The type of synchronization achieved through CountDownLatch is similar to that of Join. Assume that there is a thread "M" which needs to wait for other worker threads "T1", "T2", "T3" to complete its tasks Prior to Java 1.5, the way this can be done is, M running the following code
T1.join();
T2.join();
T3.join();
The above code makes sure that thread M resumes its work after T1, T2, T3 completes its work. T1, T2, T3 can complete their work in any order.
The same can be achieved through CountDownLatch, where T1,T2, T3 and thread M share same CountDownLatch object.
"M" requests : countDownLatch.await();
where as "T1","T2","T3" does countDownLatch.countdown();
One disadvantage with the join method is that M has to know about T1, T2, T3. If there is a new worker thread T4 added later, then M has to be aware of it too. This can be avoided with CountDownLatch. After implementation the sequence of action would be [T1,T2,T3](the order of T1,T2,T3 could be anyway) -> [M]
If You need to access SQL server on hostgator remotely using SSMS, you need to white list your IP in hostgator. Usually it takes 1 hour to open port for the whitelisted IP
I bumped into this problem on a cPanel CentOS 6 linux machine. The solution for me was to symlink the cPanel git to /usr/local/bin/git
ln -s /usr/local/cpanel/3rdparty/bin/git /usr/local/bin/git
you can try this.Add the parameter as output direction and after executing the query get the output parameter value.
SqlParameter parmOUT = new SqlParameter("@return", SqlDbType.Int);
parmOUT.Direction = ParameterDirection.Output;
cmd.Parameters.Add(parmOUT);
cmd.ExecuteNonQuery();
int returnVALUE = (int)cmd.Parameters["@return"].Value;
Suposse you have
Class1
public class Class1 {
//Your class code above
}
Class2
public class Class2 {
}
and then you can use Class2 in different ways.
Class Field
public class Class1{
private Class2 class2 = new Class2();
}
Method field
public class Class1 {
public void loginAs(String username, String password)
{
Class2 class2 = new Class2();
class2.invokeSomeMethod();
//your actual code
}
}
Static methods from Class2 Imagine this is your class2.
public class Class2 {
public static void doSomething(){
}
}
from class1 you can use doSomething from Class2 whenever you want
public class Class1 {
public void loginAs(String username, String password)
{
Class2.doSomething();
//your actual code
}
}
I wanted to change the column value in a specific row. Thanks to above answers and after some serching able to come up with below,
var dataTable = $("#yourtableid");

var columnNumber= 2;
dataTable[0].rows[rowNumber].cells[columnNumber].innerHTML = 'New Content';
A lot of people use (click) option so I will share this too.
<button (click)="function1()" (click)="function2()">Button</button>
You can try this

You might need to collect the stats as you go, but @@ROWCOUNT
captures this:
declare @Fish table (
Name varchar(32)
)
insert into @Fish values ('Cod')
insert into @Fish values ('Salmon')
insert into @Fish values ('Butterfish')
update @Fish set Name = 'LurpackFish' where Name = 'Butterfish'
select @@ROWCOUNT --gives 1
update @Fish set Name = 'Dinner'
select @@ROWCOUNT -- gives 3
If you not have configured a billing account with your credit card, the API do not work. The Google is now very hungry for money and not open more your products "free". Obviously that him offer a free limited access number of consults and over this acces, the billing is very high.
No need to include CSS or image files. No need to include that whole heavy-artillery jQuery UI library. I wrote a lightweight jQuery plugin that does the magic for you. All you need is jQuery
and the plugin. =)
Fiddle here: jQuery InputSearch demo.
getdate()
is the direct equivalent, but you should always use UTC datetimes
getutcdate()
whether your app operates across timezones or not - otherwise you run the risk of screwing up date math at the spring/fall transitions
obj={};
$.each(obj, function (key, value) {
console.log(key+ ' : ' + value); //push the object value
});
for (var i in obj) {
nameList += "" + obj[i] + "";//display the object value
}
$("id/class").html($(nameList).length);//display the length of object.
Arrays
in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here).
Instead, use a List
:
ArrayList<String> mylist = new ArrayList<String>();
mylist.add(mystring); //this adds an element to the list.
Of course, if you know beforehand how many strings you are going to put in your array, you can create an array of that size and set the elements by using the correct position:
String[] myarray = new String[numberofstrings];
myarray[23] = string24; //this sets the 24'th (first index is 0) element to string24.
Open the terminal in ubuntu (ctrl+shift+t)
sudo gedit /etc/tomcat7/server.xml
change the default port in the server.xml,from 8080 to anything like 8081,8181,8008. Then save the file .
Now the project will work nicely without any interruption.
You are calling nextElement twice. Refactor like this:
while(e.hasMoreElements()){
String param = (String) e.nextElement();
System.out.println(param);
}
@SpringBootApplication
annotation missing in your spring boot starter class.
web application type
in properties file:In application.properties
:
spring.main.web-application-type=none
If you use application.yml
then add:
spring:
main:
web-application-type: none
*SpringBootServletInitializer*
in main class.@SpringBootApplication
public class YourAppliationName extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(YourAppliationName.class, args);
}
}
If you use spring-boot-starter-webflux
then also add spring-boot-starter-web
as dependency.
Run change detection explicitly after the change:
import { ChangeDetectorRef } from '@angular/core';
constructor(private cdRef:ChangeDetectorRef) {}
ngAfterViewChecked()
{
console.log( "! changement de la date du composant !" );
this.dateNow = new Date();
this.cdRef.detectChanges();
}
Hi i used this solution works perfectly.No Need to check, just use https.
<script language="javascript" type="text/javascript">
document.location="https:" + window.location.href.substring(window.location.protocol.length, window.location.href.length);
</script>
You can also simply inject the location into the scope and use that to deduct the style for the navigation:
function IndexController( $scope, $rootScope, $location ) {
$rootScope.location = $location;
...
}
Then use it in your ng-class
:
<li ng-class="{active: location.path() == '/search'}">
<a href="/search">Search><a/>
</li>
You typically restore purchases with this code:
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
It will reinvoke -paymentQueue:updatedTransactions
on the observer(s) for the purchased items. This is useful for users who reinstall the app after deletion or install it on a different device.
Not all types of In-App purchases can be restored.
You can parse the existing XML file into DOM and append new elements to the DOM. Very similar to what you did with creating brand new XML. I am assuming you do not have to worry about duplicate server. If you do have to worry about that, you will have to go through the elements in the DOM to check for duplicates.
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
/* parse existing file to DOM */
Document document = documentBuilder.parse(new File("exisgint/xml/file"));
Element root = document.getDocumentElement();
for (Server newServer : Collection<Server> bunchOfNewServers){
Element server = Document.createElement("server");
/* create and setup the server node...*/
root.appendChild(server);
}
/* use whatever method to output DOM to XML (for example, using transformer like you did).*/
Check local_listener definition in your spfile or pfile. In my case, the problem was with pfile, I had moved the pfile from a similar environment and it had LISTENER_sid as LISTENER and not just LISTENER.
You can do this with PowerShell:
$process = Start-Process "javaw" "-jar start.jar" -PassThru
taskkill /pid $process.Id
The taskkill
command will graceful close the application.
Use the onclick

Checkout a project called Uploadify. http://www.uploadify.com/
It's a Flash + jQuery based file uploader. This uses Flash's file selection dialog, which gives you the ability to filter file types, select multiple files at the same time, etc.
One shouldn't use set_yticklabels
to change the fontsize, since this will also set the labels (i.e. it will replace any automatic formatter by a FixedFormatter
), which is usually undesired. The easiest is to set the respective tick_params
:
ax.tick_params(axis="x", labelsize=8)
ax.tick_params(axis="y", labelsize=20)
or
ax.tick_params(labelsize=8)
in case both axes shall have the same size.
Of course using the rcParams as in @tmdavison's answer is possible as well.
To check if a value is contained within a set of variables you can use the inbuilt modules itertools
and operator
.
For example:
Imports:
from itertools import repeat
from operator import contains
Declare variables:
x = 0
y = 1
z = 3
Create mapping of values (in the order you want to check):
check_values = (0, 1, 3)
Use itertools
to allow repetition of the variables:
check_vars = repeat((x, y, z))
Finally, use the map
function to create an iterator:
checker = map(contains, check_vars, check_values)
Then, when checking for the values (in the original order), use next()
:
if next(checker) # Checks for 0
# Do something
pass
elif next(checker) # Checks for 1
# Do something
pass
etc...
This has an advantage over the lambda x: x in (variables)
because operator
is an inbuilt module and is faster and more efficient than using lambda
which has to create a custom in-place function.
Another option for checking if there is a non-zero (or False) value in a list:
not (x and y and z)
Equivalent:
not all((x, y, z))
The read_sql
docs say this params
argument can be a list, tuple or dict (see docs).
To pass the values in the sql query, there are different syntaxes possible: ?
, :1
, :name
, %s
, %(name)s
(see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2
in your case I suppose).
In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2
documentation, they support the %(name)s
style (and so not the :name
I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:
df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
index_col=['Timestamp'])
This prints all elements that contain sub:
for s in filter (lambda x: sub in x, list): print (s)
Create the SqlParamObject which would give you control to access methods on the parameters
:
SqlParameter param = new SqlParameter();
SET the Name for your paramter (it should b same as you would have declared a variable to hold the value in your DataBase)
: param.ParameterName = "@yourParamterName";
Clear the value holder to hold you output data
: param.Value = 0;
Set the Direction of your Choice (In your case it should be Output)
: param.Direction = System.Data.ParameterDirection.Output;
One difference we can note in Windows is:
If you use Runtime.getRuntime().exec("rmiregistry 1024");
you can see rmiregistry.exe process will run in your Task Manager
whereas if you use Registry registry = LocateRegistry.createRegistry(1024);
you can not see the process running in Task Manager,
I think Java handles it in a different way.
and this is my server.policy file
Before running the the application, make sure that you killed all your existing javaw.exe and rmiregistry.exe corresponds to your rmi programs which are already running.
The following code works for me by using Registry.LocateRegistry()
or
Runtime.getRuntime.exec("");
// Standard extensions get all permissions by default
grant {
permission java.security.AllPermission;
};
VM argument
-Djava.rmi.server.codebase=file:\C:\Users\Durai\workspace\RMI2\src\
Code:
package server;
import java.rmi.Naming;
import java.rmi.RMISecurityManager;
import java.rmi.Remote;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
public class HelloServer
{
public static void main (String[] argv)
{
try {
if(System.getSecurityManager()==null){
System.setProperty("java.security.policy","C:\\Users\\Durai\\workspace\\RMI\\src\\server\\server.policy");
System.setSecurityManager(new RMISecurityManager());
}
Runtime.getRuntime().exec("rmiregistry 1024");
// Registry registry = LocateRegistry.createRegistry(1024);
// registry.rebind ("Hello", new Hello ("Hello,From Roseindia.net pvt ltd!"));
//Process process = Runtime.getRuntime().exec("C:\\Users\\Durai\\workspace\\RMI\\src\\server\\rmi_registry_start.bat");
Naming.rebind ("//localhost:1024/Hello",new Hello ("Hello,From Roseindia.net pvt ltd!"));
System.out.println ("Server is connected and ready for operation.");
}
catch (Exception e) {
System.out.println ("Server not connected: " + e);
e.printStackTrace();
}
}
}
Here is a good example in Python3.
>>> a = input("What is your name?")
What is your name?Peter
>>> b = input("Where are you from?")
Where are you from?DE
>>> print("So you are %s of %s" % (a, b))
So you are Peter of DE
It's good practice to use a context manager or call close()
in case of exceptions during the file saving process. Could happen if your storage backend is down, etc.
Any overwrite behavior should be configured in your storage backend. For example S3Boto3Storage has a setting AWS_S3_FILE_OVERWRITE
. If you're using FileSystemStorage
you can write a custom mixin.
You might also want to call the model's save method instead of the FileField's save method if you want any custom side-effects to happen, like last-updated timestamps. If that's the case, you can also set the name attribute of the file to the name of the file - which is relative to MEDIA_ROOT
. It defaults to the full path of the file which can cause problems if you don't set it - see File.__init__() and File.name.
Here's an example where self
is the model instance where my_file
is the FileField / ImageFile, calling save()
on the whole model instance instead of just FileField:
import os
from django.core.files import File
with open(filepath, 'rb') as fi:
self.my_file = File(fi, name=os.path.basename(fi.name))
self.save()
As explained in Python's super() considered super, one way is to have class eat the arguments it requires, and pass the rest on. Thus, when the call-chain reaches object
, all arguments have been eaten, and object.__init__
will be called without arguments (as it expects). So your code should look like this:
class A(object):
def __init__(self, *args, **kwargs):
print "A"
super(A, self).__init__(*args, **kwargs)
class B(object):
def __init__(self, *args, **kwargs):
print "B"
super(B, self).__init__(*args, **kwargs)
class C(A):
def __init__(self, arg, *args, **kwargs):
print "C","arg=",arg
super(C, self).__init__(*args, **kwargs)
class D(B):
def __init__(self, arg, *args, **kwargs):
print "D", "arg=",arg
super(D, self).__init__(*args, **kwargs)
class E(C,D):
def __init__(self, arg, *args, **kwargs):
print "E", "arg=",arg
super(E, self).__init__(*args, **kwargs)
print "MRO:", [x.__name__ for x in E.__mro__]
E(10, 20, 30)
if(FALSE) {
...
}
precludes multiple lines from being executed. However, these lines still have to be syntactically correct, i.e., can't be comments in the proper sense. Still helpful for some cases though.
This gets a little complicated. These objects are custom classes or structs, and looking inside them is not as easy on Xcode as in other development environments.
If I were you, I'd NSLog the values you want to see, with some description.
i.e:
NSLog(@"Description of object & time: %i", indexPath.row);

If you know the extension, you can use basename
$ basename /home/jsmith/base.wiki .wiki
base
Where df1 is your original data frame:
df2 <- subset(df1, select = c(1, 2, 5))
Here is a performance comparison of the proposed methods in other answers.
> foo <- sapply(letters, function(x){runif(5)}, simplify = FALSE)
> microbenchmark::microbenchmark('k' %in% names(foo),
is.null(foo[['k']]),
exists('k', where = foo))
Unit: nanoseconds
expr min lq mean median uq max neval cld
"k" %in% names(foo) 467 933 1064.31 934 934 10730 100 a
is.null(foo[["k"]]) 0 0 168.50 1 467 3266 100 a
exists("k", where = foo) 6532 6998 7940.78 7232 7465 56917 100 b
If you are planing to use the list as a fast dictionary accessed many times, then the is.null
approach might be the only viable option. I assume it is O(1), while the %in%
approach is O(n)?
here is how you can perform simply, make a drawable resource file in drawable.xml. Say round_button.xml and then paste the following code.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:shape="oval">
<solid
android:color="@color/button_start_gradient_color"/>
</shape>
</item>
<item
android:drawable="@drawable/microphone"/>
</layer-list>
Note:- use your own color and drawable resource as i have used @drawable/microphone
