Not sure what you call FIFO these days since Queue is FILO, but when I was a student we used the Stack<E>
with the simple push, pop, and a peek... It is really that simple, no need for complicating further with Queue and whatever the accepted answer suggests.
What about to use replaceAll
java.lang.String method:
String str = "qwerty-1qwerty-2 455 f0gfg 4";
str = str.replaceAll("[^-?0-9]+", " ");
System.out.println(Arrays.asList(str.trim().split(" ")));
Output:
[-1, -2, 455, 0, 4]
Description
[^-?0-9]+
[
and ]
delimites a set of characters to be single matched, i.e., only one time in any order^
Special identifier used in the beginning of the set, used to indicate to match all characters not present in the delimited set, instead of all characters present in the set.+
Between one and unlimited times, as many times as possible, giving back as needed-?
One of the characters “-” and “?”0-9
A character in the range between “0” and “9”Take out the parentheses and the curly braces, neither are required when adding columns.
At my day job I sit behind a corporate firewall protecting and caching web traffic (among other things). For the most part it stays out of the way. But sometimes it rears its ugly head and stands firmly in the path of what I am trying to do.
Earlier this week I was trying to look at a cool new general validation system for ColdFusion called Validat, put out by the great guys at Alagad. They don't have a download on the RIAForge site yet, but the files are available via SVN. I loaded up the subclipse plugin into my Eclipse, restarted and began adding the Validat SVN repository. I started getting errors abou the "RA layer request failed" and "svn: PROPFIND request failed on /Validat/trunk", followed by an error about not being able to connect to the SVN server.
I already had Eclipse setup with my proxy settings, so I thought I was doing something wrong or Alagad didn't actually have the subversion repository up-and-available. After going home that night, I tried it from home and wa-la it worked. Stupid proxy server! So the subclipse plugin won't use the Eclipse proxy settings. (Can that be fixed please!). After digging around the subclipse help site and being redirected to the collab.net help, then unproductively searching through the eclipse workspace, plugins, and configuration folders for the settings file, I was finally able to figure out how to set up subclipse to use the proxy server.
In my Windows development environment, I opened the following file: C:\Documents and Settings\MyUserId\Application Data\Subversion\servers in my favorite text editor. Near the bottom of that file is a [global] section with http-proxy-host and http-proxy-port settings. I uncommented those two lines, modified them for my corporate proxy server, went back to the SVN Repository view in Eclipse, refreshed the Validat repository and Boom! it worked!

Update: I should have probably started with this as your projects are SNAPSHOTs. It is part of the SNAPSHOT semantics that Maven will check for updates on each build. Being a SNAPSHOT means that it is volatile and subject to change so updates should be checked for. However it's worth pointing out that the Maven super POM configures central to have snapshots disabled, so Maven shouldn't ever check for updates for SNAPSHOTs on central unless you've overridden that in your own pom/settings.
You can configure Maven to use a mirror for the central repository, this will redirect all requests that would normally go to central to your internal repository.
In your settings.xml you would add something like this to set your internal repository as as mirror for central:
<mirrors>
<mirror>
<id>ibiblio.org</id>
<name>ibiblio Mirror of http://repo1.maven.org/maven2/</name>
<url>http://path/to/my/repository</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
If you are using a repository manager like Nexus for your internal repository. You can set up a proxy repository for proxy central, so any requests that would normally go to Central are instead sent to your proxy repository (or a repository group containing the proxy), and subsequent requests are cached in the internal repository manager. You can even set the proxy cache timeout to -1, so it will never request for contents from central that are already on the proxy repository.
A more basic solution if you are only working with local repositories is to set the updatePolicy for the central repository to "never", this means Maven will only ever check for artifacts that aren't already in the local repository. This can then be overridden at the command line when needed by using the -U switch to force Maven to check for updates.
You would configure the repository (in your pom or a profile in the settings.xml) as follows:
<repository>
<id>central</id>
<url>http://repo1.maven.org/maven2</url>
<updatePolicy>never</updatePolicy>
</repository>
Using Angular 4 and the cli that came with it I was able to start the server with $npm start -- --port 8000
. That worked ok: ** NG Live Development Server is listening on localhost:8000, open your browser on http://localhost:8000 **
Got the tip from Here
I would not use .at for performance reasons.
Define a struct:
//#pragma pack(push, 2) //not useful (see comments below)
struct RGB {
uchar blue;
uchar green;
uchar red; };
And then use it like this on your cv::Mat image:
RGB& rgb = image.ptr<RGB>(y)[x];
image.ptr(y) gives you a pointer to the scanline y. And iterate through the pixels with loops of x and y
using System.IO;
...
Directory.CreateDirectory(@"C:\MP_Upload");
Directory.CreateDirectory does exactly what you want: It creates the directory if it does not exist yet. There's no need to do an explicit check first.
Any and all directories specified in path are created, unless they already exist or unless some part of path is invalid. The path parameter specifies a directory path, not a file path. If the directory already exists, this method does nothing.
(This also means that all directories along the path are created if needed: CreateDirectory(@"C:\a\b\c\d")
suffices, even if C:\a
does not exist yet.)
Let me add a word of caution about your choice of directory, though: Creating a folder directly below the system partition root C:\
is frowned upon. Consider letting the user choose a folder or creating a folder in %APPDATA%
or %LOCALAPPDATA%
instead (use Environment.GetFolderPath for that). The MSDN page of the Environment.SpecialFolder enumeration contains a list of special operating system folders and their purposes.
Another way to toggle:
- (IBAction)signOnClick:(id)sender
{
if ([_signOnButton.titleLabel.text isEqualToString:@"Sign off"])
{
[sender setTitle:@"Sign on" forState:UIControlStateNormal];
}
else
{
[sender setTitle:@"Sign off" forState:UIControlStateNormal];
}
}
I was missing somehow more dynamic array of strings, where amount of strings could be varied depending on run-time selection, but otherwise strings should be fixed.
I've ended up of coding code snippet like this:
#define INIT_STRING_ARRAY(...) \
{ \
char* args[] = __VA_ARGS__; \
ev = args; \
count = _countof(args); \
}
void InitEnumIfAny(String& key, CMFCPropertyGridProperty* item)
{
USES_CONVERSION;
char** ev = nullptr;
int count = 0;
if( key.Compare("horizontal_alignment") )
INIT_STRING_ARRAY( { "top", "bottom" } )
if (key.Compare("boolean"))
INIT_STRING_ARRAY( { "yes", "no" } )
if( ev == nullptr )
return;
for( int i = 0; i < count; i++)
item->AddOption(A2T(ev[i]));
item->AllowEdit(FALSE);
}
char** ev
picks up pointer to array strings, and count picks up amount of strings using _countof
function. (Similar to sizeof(arr) / sizeof(arr[0])
).
And there is extra Ansi to unicode conversion using A2T
macro, but that might be optional for your case.
I only use var when it's clear to see what type is used.
For example, I would use var in this case, because you can see immediately that x will be of the type "MyClass":
var x = new MyClass();
I would NOT use var in cases like this, because you have to drag the mouse over the code and look at the tooltip to see what type MyFunction returns:
var x = MyClass.MyFunction();
Especially, I never use var in cases where the right side is not even a method, but only a value:
var x = 5;
(because the compiler can't know if I want a byte, short, int or whatever)
protected void btnExportExcel_Click(object sender, EventArgs e)
{
DataTable _datatable = new DataTable();
for (int i = 0; i < grdReport.Columns.Count; i++)
{
_datatable.Columns.Add(grdReport.Columns[i].ToString());
}
foreach (GridViewRow row in grdReport.Rows)
{
DataRow dr = _datatable.NewRow();
for (int j = 0; j < grdReport.Columns.Count; j++)
{
if (!row.Cells[j].Text.Equals(" "))
dr[grdReport.Columns[j].ToString()] = row.Cells[j].Text;
}
_datatable.Rows.Add(dr);
}
ExportDataTableToExcel(_datatable);
}
Responding to an earlier comment, you can change the background by variable in the "container" example if the CSS is in your php page and not in the css style sheet.
$bgimage = '[some image url];
background-image: url('<?php echo $bgimage; ?>');
Put it in an absolutely-positioned div then use clientWidth to get the displayed width of the tag. You can even set the visibility to "hidden" to hide the div:
<div id="text" style="position:absolute;visibility:hidden" >This is some text</div>
<input type="button" onclick="getWidth()" value="Go" />
<script type="text/javascript" >
function getWidth() {
var width = document.getElementById("text").clientWidth;
alert(" Width :"+ width);
}
</script>
I present you with the cleanest way ever, in the form of the world's smallest jquery plugin:
jQuery.fn.reverse = [].reverse;
Usage:
$('jquery-selectors-go-here').reverse().each(function () {
//business as usual goes here
});

The closest equivalent of C++ std::map<>
(a tree internally) is C# OrderedDictionary<>
(a tree internally), while C# OrderedDictionary<>
is missing some very important methods from C++ std::map<>
, namely: std::map::find
, std::map::lower_bound
, std::map::upper_bound
, std::map::equal_range
, and std::map
iterators
, which are basically the backbone for the previous 4 methods.
Why those 4 methods are important? Because it gives us the ability to locate the "whereabouts" of a given key, in addition to only being able to check if a key exists, or the SortedDictionary is guaranteed to be ordered.
What is "whereabouts" of a key in a std::map
? The key doesn't necessarily have to exist in the collection, we want to know the location the key might be at, usually between two iterators pointing to two adjacent existing keys respectively in the collection, so we can operate on the range the key falls into in a O(logN)
complexity. Without such 4 methods (with iterators), one has to do an O(N)
iteration through the collection every time a range is queried against a key.
You can't use IF like that. You can do what you want with AND and OR:
SELECT t.first_name,
t.last_name,
t.employid,
t.status
FROM employeetable t
WHERE ((status_flag = STATUS_ACTIVE AND t.status = 'A')
OR (status_flag = STATUS_INACTIVE AND t.status = 'T')
OR (source_flag = SOURCE_FUNCTION AND t.business_unit = 'production')
OR (source_flag = SOURCE_USER AND t.business_unit = 'users'))
AND t.first_name LIKE firstname
AND t.last_name LIKE lastname
AND t.employid LIKE employeeid;

Concatenating arrays is simple using linq extensions which come standard with .Net 4
Biggest thing to remember is that linq works with IEnumerable<T>
objects, so in order to get an array back as your result then you must use the .ToArray()
method at the end
Example of concatenating two byte arrays:
byte[] firstArray = {2,45,79,33};
byte[] secondArray = {55,4,7,81};
byte[] result = firstArray.Concat(secondArray).ToArray();
The .size() method is deprecated as of jQuery 1.8. Use the .length property instead
When I find myself thinking about using Manager
or Helper
in a class name, I consider it a code smell that means I haven't found the right abstraction yet and/or I'm violating the single responsibility principle, so refactoring and putting more effort into design often makes naming much easier.
But even well-designed classes don't (always) name themselves, and your choices partly depend on whether you're creating business model classes or technical infrastructure classes.
Business model classes can be hard, because they're different for every domain. There are some terms I use a lot, like Policy
for strategy classes within a domain (e.g., LateRentalPolicy
), but these usually flow from trying to create a "ubiquitous language" that you can share with business users, designing and naming classes so they model real-world ideas, objects, actions, and events.
Technical infrastructure classes are a bit easier, because they describe domains we know really well. I prefer to incorporate design pattern names into the class names, like InsertUserCommand,
CustomerRepository,
or SapAdapter.
I understand the concern about communicating implementation instead of intent, but design patterns marry these two aspects of class design - at least when you're dealing with infrastructure, where you want the implementation design to be transparent even while you're hiding the details.

The solution I used was to create a javascript function that uses jquery:
This will populate a dropdown object on the HTML page. Please let me know where this can be optimized - but works fine as is.
function util_PopulateDropDownListAndSelect(sourceListObject, sourceListTextFieldName, targetDropDownName, valueToSelect)
{
var options = '';
// Create the list of HTML Options
for (i = 0; i < sourceListObject.List.length; i++)
{
options += "<option value='" + sourceListObject.List[i][sourceListTextFieldName] + "'>" + sourceListObject.List[i][sourceListTextFieldName] + "</option>\r\n";
}
// Assign the options to the HTML Select container
$('select#' + targetDropDownName)[0].innerHTML = options;
// Set the option to be Selected
$('#' + targetDropDownName).val(valueToSelect);
// Refresh the HTML Select so it displays the Selected option
$('#' + targetDropDownName).selectmenu('refresh')
}

i did this and works: i have my project in D: and my batch file is in the desktop, if u have it in the same drive just ignore the first line and change de D directory in the second line
in the second line change the folder of the file, put your folder
in the third line change the name of the file
D:
cd D:\python_proyects\example_folder\

def capitalizeWords(s):
return re.sub(r'\w+', lambda m:m.group(0).capitalize(), s)
re.sub
can take a function for the "replacement" (rather than just a string, which is the usage most people seem to be familiar with). This repl function will be called with an re.Match
object for each match of the pattern, and the result (which should be a string) will be used as a replacement for that match.
A longer version of the same thing:
WORD_RE = re.compile(r'\w+')
def capitalizeMatch(m):
return m.group(0).capitalize()
def capitalizeWords(s):
return WORD_RE.sub(capitalizeMatch, s)
This pre-compiles the pattern (generally considered good form) and uses a named function instead of a lambda.
Or try adding this...
$code = @"
[DllImport("kernel32.dll")]
public static extern int GetExitCodeProcess(IntPtr hProcess, out Int32 exitcode);

[Int32]$exitCode = 0
$type::GetExitCodeProcess($process.Handle, [ref]$exitCode)
By using this code, you can still let PowerShell take care of managing redirected output/error streams, which you cannot do using System.Diagnostics.Process.Start() directly.
I am the original poster and I accepted the above answer by DGH without having first used it in the code.
Once I did use I realised that it needed a little tweaking to actually do what I needed it to do (to be fair to DGH he/she did say "or something similar" !).
I thought it was worth posting the tweak here for the benefit of others:
try:
a = Application("abcdef", "")
except pySourceAidExceptions.PathIsNotAValidOne:
pass
except:
self.assertTrue(False)
What I was attempting to do here was to ensure that if an attempt was made to instantiate an Application object with a second argument of spaces the pySourceAidExceptions.PathIsNotAValidOne would be raised.
I believe that using the above code (based heavily on DGH's answer) will do that.
If you are using cakephp version 3.0 and above, then you can add default value in select input using empty attribute as given in below example.
echo $this->Form->input('category_id', ['options'=>$categories,'empty'=>'Choose']);
You might have confusions between the different line endings. A Windows file will end each line with a carriage return and a line feed. Some programs on Unix will read that file as if it had an extra blank line between each line, because it will see the carriage return as an end of line, and then see the line feed as another end of line.
To determine which branch you are now on, look at the side bar, under BRANCHES, you are in the branch that is in BOLD LETTERS.

Decompyle++ (pycdc) was the only one that worked for me: https://github.com/zrax/pycdc
was suggested in Decompile Python 2.7 .pyc
The way to do this is to set the EnableHeadersVisualStyles
flag for the data grid view to False
, and set the background colour via the ColumnHeadersDefaultCellStyle.BackColor
property. For example, to set the background colour to blue, use the following (or set in the designer if you prefer):
_dataGridView.ColumnHeadersDefaultCellStyle.BackColor = Color.Blue;
_dataGridView.EnableHeadersVisualStyles = false;
If you do not set the EnableHeadersVisualStyles
flag to False, then the changes you make to the style of the header will not take effect, as the grid will use the style from the current users default theme. The MSDN documentation for this property is here.
First thing that should pop in a developer head while formatting a number into char sequence should be care of such details like do it will be possible to reverse the operation.
And other aspect is providing proper result. So you want to truncate the number or round it.
So before you start you should ask your self, am i interested on the value or not.
To achieve your goal you have multiple options but most of them refer to Format and Formatter, but i just suggest to look in this answer.
Did you even look at the break
keyword? O.o
This is just pseudo-code, but you should be able to see what I mean:
<?php
for(...) {
while(...) {
foreach(...) {
break 3;
}
}
}
If you think about break
being a function like break()
, then it's parameter would be the number of loops to break out of. As we are in the third loop in the code here, we can break out of all three.

$host
is a variable of the Core module.
$host
This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.
This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.
$http_host
is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER
(ref).
$http_HEADER
The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;
Summarizing:
$http_host
equals always the HTTP_HOST
request header.$host
equals $http_host
, lowercase and without the port number (if present), except when HTTP_HOST
is absent or is an empty value. In that case, $host
equals the value of the server_name
directive of the server which processed the request.That's not a good practice and there is no mechanism to do that because of that. The right way to accomplish what you want is inheritance.
Take a look into the class documentation.
A little example:
class Employee(object):
def __init__(self, age, sex, siblings=0):
self.age = age
self.sex = sex
self.siblings = siblings
def born_on(self):
today = datetime.date.today()
return today - datetime.timedelta(days=self.age*365)
class Boss(Employee):
def __init__(self, age, sex, siblings=0, bonus=0):
self.bonus = bonus
Employee.__init__(self, age, sex, siblings)
This way Boss has everything Employee
has, with also his own __init__
method and own members.
I also had the same issue. I changed it to the following and it worked.
Java :
@RequestMapping(value = "/test", method = RequestMethod.GET)
HTML code:
<form action="<%=request.getContextPath() %>/test" method="GET">
<input type="submit" value="submit">
</form>
By default if you do not specify http method in a form it uses GET. To use POST method you need specifically state it.
Hope this helps.

UPSERT support in SQLite! UPSERT syntax was added to SQLite with version 3.24.0 (pending) !
UPSERT is a special syntax addition to INSERT that causes the INSERT to behave as an UPDATE or a no-op if the INSERT would violate a uniqueness constraint. UPSERT is not standard SQL. UPSERT in SQLite follows the syntax established by PostgreSQL.
alternatively:
Another completely different way of doing this is: In my application I set my in memory rowID to be long.MaxValue when I create the row in memory. (MaxValue will never be used as an ID you will won't live long enough.... Then if rowID is not that value then it must already be in the database so needs an UPDATE if it is MaxValue then it needs an insert. This is only useful if you can track the rowIDs in your app.

A very tiny thing that annoyed me in COBOL was that there was no dedicated modulo operation. Instead you could do a division specifying that you only wanted whole number results and store the rest in a different variable. Since COBOL is very sensitive when it comes to variables that means that you ended up with a variable you didn't really need, i.e. the actual result of the division. This is the story of how I once named a variable "USELESS" - that was the most appropriate name I could think of.
The short answer is the iPhone supports H.264 video, High profile and AAC audio, in container formats .mov
, .mp4
, or MPEG Segment .ts
. MPEG Segment files are used for HTTP Live Streaming.
.mp4
container..ts
container files (see App Store Review Guidelines rule 2.5.7).On the iPhone, H.264 is the only game in town. [1]
There are several different feature tiers or "profiles" available in H.264. All modern iPhones (3GS and above) support the High profile. These profiles are basically three different levels of algorithm "tricks" used to compress the video. More tricks give better compression, but require more CPU or dedicated hardware to decode. This is a table that lists the differences between the different profiles.
[1] Interestingly, Apple's own Facetime uses the newer H.265 (HEVC) video codec. However right now (August 2017) there is no Apple-provided library that gives access to a HEVC codec to developers. This is expected to change at some point.
In talking about what video format the iPhone supports, a distinction should be made between what the hardware can support, and what the (much lower) limits are for playback when streaming over a network.
The only data given about hardware video support by Apple about the current generation of iPhones (SE, 6S, 6S Plus, 7, 7 Plus) is that they support
4K [3840x2160] video recording at 30 fps
1080p [1920x1080] HD video recording at 30 fps or 60 fps.
Obviously the phone can play back what it can record, so we can guess that 3840x2160 at 30 fps and 1920x1080 at 60 fps represent design limits of the phone. In addition, the screen size on the 6S Plus and 7 Plus is 1920x1080. So if you're interested in playback on the phone, it doesn't make sense to send over more pixels then the screen can draw.
However, streaming video is a different matter. Since networks are slow and video is huge, it's typical to use lower resolutions, bitrates, and frame rates than the device's theoretical maximum.
The most detailed document giving recommendations for streaming is TN2224 Best Practices for Creating and Deploying HTTP Live Streaming Media for Apple Devices. Figure 3 in that document gives a table of recommended streaming parameters:
As you can see, Apple recommends the relatively low resolution of 768x432 as the highest recommended resolution for streaming over a cellular network. Of course this is just a recommendation and YMMV.
The question is about video, but that video generally has one or more audio tracks with it. The iPhone supports a few audio formats, but the most modern and by far most widely used is AAC. The iPhone 7 / 7 Plus, 6S Plus / 6S, SE all support AAC bitrates of 8 to 320 Kbps.
The audio and video tracks go inside a container. The purpose of the container is to combine (interleave) the different tracks together, to store metadata, and to support seeking. The iPhone supports
The .mov
and .mp4
file formats are closely related (.mp4
is in fact based on .mov
), however .mp4
is an ISO standard that has much wider support.
As noted above, you have to use MPEG-TS for videos longer than 10 minutes.
It depends on what concrete List class you are using. The abstract class AbstractCollection has a method called containsAll(Collection) that takes another collection ( a List is a collection) and:
Returns true if this collection contains all of the elements in the specified collection.
So if an ArrayList is being passed in you can call this method to see if they are exactly the same.
List foo = new ArrayList();
List bar = new ArrayList();
String str = "foobar";
foo.add(str);
bar.add(str);
foo.containsAll(bar);
The reason for containsAll() is because it iterates through the first list looking for the match in the second list. So if they are out of order equals() will not pick it up.
EDIT: I just want to make a comment here about the amortized running time of performing the various options being offered. Is running time important? Sure. Is it the only thing you should consider? No.
The cost of copying EVERY single element from your lists into other lists takes time, and it also takes up a good chunk of memory (effectively doubling the memory you are using).
So if memory in your JVM isn't a concern (which it should generally be) then you still need to consider the time it takes to copy every element from two lists into two TreeSets. Remember it is sorting every element as it enters them.
My final advice? You need to consider your data set and how many elements you have in your data set, and also how large each object in your data set is before you can make a good decision here. Play around with them, create one each way and see which one runs faster. It's a good exercise.
Why don't you create service and put logic in onCreate()

You could use screen

...or alternatively if you only want to show a portion of the time value use "Custom":
timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Custom;
timePicker.CustomFormat = "HH:mm"; // Only use hours and minutes
timePicker.ShowUpDown = true;
If you are often programming dynamic stored procedures, you will fall in love with your second example (using where). If you have various input parameters and lots of morph mess, then that is the only way. Otherwise, they both will run the same query plan so there is definitely no obvious difference in classic queries.
I dont think youre returning json object from server. just a string.
you need the dataType of the return object to be json
As oxbow_lakes mentions, you can use reflection to get around the access restrictions (assuming your SecurityManager will let you).
That said, if this class is so badly designed that it makes you resort to such hackery, maybe you should look for an alternative. Sure this little hack might be saving you a few hours now, but how much will it cost you down the road?
You don't need to parse the string, it's defined as a string already.
Just do:
private static String getStringInput (String prompt) {
String input = EZJ.getUserInput(prompt);
return input;
}
I found fiddling with styles.xml and activity to be too cumbersome hence created a common utility method which has below options set
Java
Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
window.setStatusBarColor(Color.TRANSPARENT);
Kotlin DSL
activity.window.apply {
clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
statusBarColor = Color.TRANSPARENT
}
And that's all it took to achieve transparent status bar. Hope this helps.
You can create a pandas Series
, using the primary list as data
and the other list as index
, and then just sort by the index:
import pandas as pd
pd.Series(data=X,index=Y).sort_index().tolist()
output:
['a', 'd', 'h', 'b', 'c', 'e', 'i', 'f', 'g']
You can use the Path
api:
Path p = Paths.get(yourFileNameUri);
Path folder = p.getParent();
flowLayout
is UICollectionViewFlowLayout
property
override func scrollViewWillEndDragging(scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
if let collectionView = collectionView {
targetContentOffset.memory = scrollView.contentOffset
let pageWidth = CGRectGetWidth(scrollView.frame) + flowLayout.minimumInteritemSpacing
var assistanceOffset : CGFloat = pageWidth / 3.0
if velocity.x < 0 {
assistanceOffset = -assistanceOffset
}
let assistedScrollPosition = (scrollView.contentOffset.x + assistanceOffset) / pageWidth
var targetIndex = Int(round(assistedScrollPosition))
if targetIndex < 0 {
targetIndex = 0
}
else if targetIndex >= collectionView.numberOfItemsInSection(0) {
targetIndex = collectionView.numberOfItemsInSection(0) - 1
}
print("targetIndex = \(targetIndex)")
let indexPath = NSIndexPath(forItem: targetIndex, inSection: 0)
collectionView.scrollToItemAtIndexPath(indexPath, atScrollPosition: .Left, animated: true)
}
}
You could use UIPageViewController
if it meets your requirements, each page would have a separate view controller.
If you do not want to use other library, here is a simple function to convert InputStream
to OutputStream
.
public static void copyStream(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1) {
out.write(buffer, 0, read);
}
}
Now you can easily write an Inputstream
into file by using FileOutputStream
-
FileOutputStream out = new FileOutputStream(outFile);
copyStream (inputStream, out);
out.close();
i couldnt find though what i should add exactly to the configuration file to set up the password.
Configuration file should be located at /etc/redis/redis.conf
and password can be set up in SECURITY section which should be located between REPLICATION and LIMITS section. Password setup is done using the requirepass directive. For more information try to look at AUTH command description.
O(n),I would say . I am doing for a balanced tree,applicable for all the trees. Assuming that you use recursion,
T(n) = 2*T(n/2) + 1 ----------> (1)
T(n/2) for left sub-tree and T(n/2) for right sub-tree and '1' for verifying the base case.
On Simplifying (1) you can prove that the traversal(either inorder or preorder or post order) is of order O(n).
For a one time change you can do this:
export EMAIL='[email protected]'; mutt -s "Elvis is dead" [email protected]
Use Spotlight.
But only the last simulator will be opened. If you used iPad Air 2
last time, Spotlight will open it. If you wanna open iPhone 6s
this time, that's a problem.
Below query worked for me with default value false;
ALTER TABLE cti_contract_account ADD ready_to_audit BIT DEFAULT 0 NOT NULL;
There's nothing wrong with saving the whole history in the database, they are prepared for that kind of tasks.
Actually you can find here in Stack Overflow a link to an example schema for a chat: example
If you are still worried for the size, you could apply some optimizations to group messages, like adding a buffer to your application that you only push after some time (like 1 minute or so); that way you would avoid having only 1 line messages
Here's a Swift extension on UIColor
that takes a hex string:
import UIKit
extension UIColor {
convenience init(hexString: String) {
// Trim leading '#' if needed
var cleanedHexString = hexString
if hexString.hasPrefix("#") {
// cleanedHexString = dropFirst(hexString) // Swift 1.2
cleanedHexString = String(hexString.characters.dropFirst()) // Swift 2
}
// String -> UInt32
var rgbValue: UInt32 = 0
NSScanner(string: cleanedHexString).scanHexInt(&rgbValue)
// UInt32 -> R,G,B
let red = CGFloat((rgbValue >> 16) & 0xff) / 255.0
let green = CGFloat((rgbValue >> 08) & 0xff) / 255.0
let blue = CGFloat((rgbValue >> 00) & 0xff) / 255.0
self.init(red: red, green: green, blue: blue, alpha: 1.0)
}
}
If you want to stick to an array then this way you can make use. But its not good as compared to List and not recommended. However it will solve your problem.
import java.util.Scanner;
public class ArrayModify {
public static void main(String[] args) {
int[] list;
String st;
String[] stNew;
Scanner scan = new Scanner(System.in);
System.out.println("Enter Numbers: "); // If user enters 5 6 7 8 9
st = scan.nextLine();
stNew = st.split("\\s+");
list = new int[stNew.length]; // Sets array size to 5
for (int i = 0; i < stNew.length; i++){
list[i] = Integer.parseInt(stNew[i]);
System.out.println("You Enterred: " + list[i]);
}
}
}

For clarity, the formulas that use a square root need to be
sqrt(coefficient * (colour_value^2))
not
sqrt((coefficient * colour_value))^2
The proof of this lies in the conversion of a R=G=B triad to greyscale R. That will only be true if you square the colour value, not the colour value times coefficient. See Nine Shades of Greyscale
You almost had it, just need to escape special regex chars:
regex = /http\:\/\/www\.youtube\.com\/watch\?v=([\w-]{11})/;
url = 'http://www.youtube.com/watch?v=Ahg6qcgoay4';
id = url.match(regex)[1]; // id = 'Ahg6qcgoay4'
Edit: Fix for regex by soupagain.
Here's the steps to achieve this:
Download the sendmail.zip through this link
Open sendmail.ini and set the configuration as follows:
smtp_server=smtp.gmail.com
hostname=localhost
Access your email account. Click the Gear Tool > Settings > Forwarding and POP/IMAP > IMAP access. Click "Enable IMAP", then save your changes.
Run your WAMP Server. Enable ssl_module under Apache Module.
Next, enable php_openssl and php_sockets under PHP.
Open php.ini and configure it as the codes below. Basically, you just have to set the sendmail_path.
[mail function] ; For Win32 only. ; http://php.net/smtp ;SMTP = ; http://php.net/smtp-port ;smtp_port = 25 ; For Win32 only. ; http://php.net/sendmail-from ;sendmail_from = [email protected] ; For Unix only. You may supply arguments as well (default: "sendmail -t -i"). ; http://php.net/sendmail-path sendmail_path = "C:\wamp\sendmail\sendmail.exe -t -i"
I hope this will work for you..

A simple function to get the history similar to unix/bash version.
Hope it helps some new folks.
def ipyhistory(lastn=None):
"""
param: lastn Defaults to None i.e full history. If specified then returns lastn records from history.
Also takes -ve sequence for first n history records.
"""
import readline
assert lastn is None or isinstance(lastn, int), "Only integers are allowed."
hlen = readline.get_current_history_length()
is_neg = lastn is not None and lastn < 0
if not is_neg:
flen = len(str(hlen)) if not lastn else len(str(lastn))
for r in range(1,hlen+1) if not lastn else range(1, hlen+1)[-lastn:]:
print(": ".join([str(r if not lastn else r + lastn - hlen ).rjust(flen), readline.get_history_item(r)]))
else:
flen = len(str(-hlen))
for r in range(1, -lastn + 1):
print(": ".join([str(r).rjust(flen), readline.get_history_item(r)]))
Snippet: Tested with Python3. Let me know if there are any glitches with python2. Samples:
Full History :
ipyhistory()
Last 10 History:
ipyhistory(10)
First 10 History:
ipyhistory(-10)
Hope it helps fellas.
Fast, simple, but maybe not always right:
>>> [x for x in mylist if x.isdigit()]
['1', '2', '3', '4']
More traditional if you need to get numbers:
new_list = []
for value in mylist:
try:
new_list.append(int(value))
except ValueError:
continue
Note: The result has integers. Convert them back to strings if needed, replacing the lines above with:
try:
new_list.append(str(int(value)))

I have the same problem and it annoys me tremendously!!
I have always thought I was surposed to do as answer 2. That used to work in Intellij 9 (now using 10).
However I figured out that by adding these line to my maven pom file helps:
<build>
...
<resources>
<resource>
<directory>src/main/resources</directory>
</resource>
</resources>
...
</build>
set meta tag in head as
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
use the link http://www.i18nqa.com/debug/utf8-debug.html to replace the symbols character you want.
then use str_replace like
$find = array('“', '’', '…', '—', '–', '‘', 'é', 'Â', '•', 'Ëœ', 'â€'); // en dash
$replace = array('“', '’', '…', '—', '–', '‘', 'é', '', '•', '˜', '”');
$content = str_replace($find, $replace, $content);
Its the method i use and help alot. Thanks!
substring().

This occurs because of this issue also i.e repackaging which you defined in POM file.
Remove this from pom file under maven plugin. It will work
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
I suppose because you didn't specify plugin version so it triggers the download of associated metadata in order to get the last one.
Otherwise did you try to force local repo usage using -o ?
Use the DO statement, a new option in version 9.0:

It's probably caused by a local network connectivity issue (but also a DNS error is possible). Unfortunately HResult
is generic, however you can determine the exact issue catching HttpRequestException
and then inspecting InnerException
: if it's a WebException
then you can check the WebException.Status
property, for example WebExceptionStatus.NameResolutionFailure
should indicate a DNS resolution problem.
It may happen, there isn't much you can do.
What I'd suggest to always wrap that (network related) code in a loop with a try
/catch
block (as also suggested here for other fallible operations). Handle known exceptions, wait a little (say 1000 msec) and try again (for say 3 times). Only if failed all times then you can quit/report an error to your users. Very raw example like this:
private const int NumberOfRetries = 3;
private const int DelayOnRetry = 1000;
public static async Task<HttpResponseMessage> GetFromUrlAsync(string url) {
using (var client = new HttpClient()) {
for (int i=1; i <= NumberOfRetries; ++i) {
try {
return await client.GetAsync(url);
}
catch (Exception e) when (i < NumberOfRetries) {
await Task.Delay(DelayOnRetry);
}
}
}
}
It will have already gone back before it executes the reload.
You would be better off to replace:
window.history.back();
location.reload();
with:
window.location.replace("pagehere.html");
SELECT column_name from table_name
WHERE RTRIM(ISNULL(column_name, '')) LIKE ''
ISNULL(column_name, '')
will return '' if column_name is NULL, otherwise it will return column_name.
UPDATE
In Oracle, you can use NVL
to achieve the same results.
SELECT column_name from table_name
WHERE RTRIM(NVL(column_name, '')) LIKE ''
self.automaticallyAdjustsScrollViewInsets = NO;
try, you can deal with it!

Your code fails because you are executing a method (addOption) on the jQuery object (and this object does not support the method)
You can use the standard Javascript function like this:
$("#dropListBuilding")[0].options.add( new Option("My Text","My Value") )
You can use duplicated

I have looked all over for a good example of encryption and decryption process but most were overly complex.
Anyhow there are many reasons someone may want to decrypt some text values including passwords. The reason I need to decrypt the password on the site I am working on currently is because they want to make sure when someone is forced to change their password when it expires that we do not let them change it with a close variant of the same password they used in the last x months.
So I wrote up a process that will do this in a simplified manner. I hope this code is beneficial to someone. For all I know I may end up using this at another time for a different company/site.
public string GenerateAPassKey(string passphrase)
{
// Pass Phrase can be any string
string passPhrase = passphrase;
// Salt Value can be any string(for simplicity use the same value as used for the pass phrase)
string saltValue = passphrase;
// Hash Algorithm can be "SHA1 or MD5"
string hashAlgorithm = "SHA1";
// Password Iterations can be any number
int passwordIterations = 2;
// Key Size can be 128,192 or 256
int keySize = 256;
// Convert Salt passphrase string to a Byte Array
byte[] saltValueBytes = Encoding.ASCII.GetBytes(saltValue);
// Using System.Security.Cryptography.PasswordDeriveBytes to create the Key
PasswordDeriveBytes pdb = new PasswordDeriveBytes(passPhrase, saltValueBytes, hashAlgorithm, passwordIterations);
//When creating a Key Byte array from the base64 string the Key must have 32 dimensions.
byte[] Key = pdb.GetBytes(keySize / 11);
String KeyString = Convert.ToBase64String(Key);
return KeyString;
}
//Save the keystring some place like your database and use it to decrypt and encrypt
//any text string or text file etc. Make sure you dont lose it though.

The original answer the author gave works pretty well. Just to extend this idea, you can do something like
group by datediff(minute, 0, [Date])/10
which will allow you to group by a longer period then 60 minutes, say 720, which is half a day etc.
Initially cursor is not on the first row show using moveToNext()
you can iterate the cursor when record is not exist then it return false
,unless it return true
,
while (cursor.moveToNext()) {
...
}
Yes! There's a Python debugger called pdb
just for doing that!
You can launch a Python program through pdb
by using pdb myscript.py
or python -m pdb myscript.py
.
There are a few commands you can then issue, which are documented on the pdb
page.
Some useful ones to remember are:
b
: set a breakpointc
: continue debugging until you hit a breakpoints
: step through the coden
: to go to next line of codel
: list source code for the current file (default: 11 lines including the line being executed)u
: navigate up a stack framed
: navigate down a stack framep

As BMSAndroidDroid said, this problem may be caused by a wrong build path configuration.
If you included some libraries to your build path, then move the libraries, the build path will conserve the wrong references, will not found the libraries during compilation and you will get an error.
To fix it, right click on your project folder > build path > configure build path Then take a look to the library tab, and remove the old libraries.
As other answers suggest... Some guy (for whatever reason) decided that your old code should not work when you upgrade your PHP, because he knows better than you and don't care about what your code does or how simple it is for you to upgrade.
Well, if you can't upgrade your project overnight you can
downgrade your version of PHP to whatever version that worked
or...
use a shim (kind of polyfill) such as https://github.com/dshafik/php7-mysql-shim or https://github.com/dotpointer/mysql-shim, and then find a place for
include_once("choice_shim.php");
somewhere in your code
That will keep your old PHP code up and running until you are in a mood to update...

Just to add to the confusion, I've been working on a simple text editor using a TextArea element in an HTML page in a browser. In anticipation of compatibility woes with respect to CR/LF, I wrote the code to check the platform, and use whichever newline convention was applicable to the platform.
However, I discovered something interesting when checking the actual characters contained in the TextArea, via a small JavaScript function that generates the hex data corresponding to the characters.
For the test, I typed in the following text:
Hello, World[enter]
Goodbye, Cruel World[enter]
When I examined the text data, the byte sequence I obtained was this:
48 65 6c 6c 6f 2c 20 57 6f 72 6c 64 0a 47 6f 6f 64 62 79 65 2c 20 43 72 75 65 6c 20 57 6f 72 6c 64 0a
Now, most people looking at this, and seeing 0a but no 0d bytes, would think that this output was obtained on a Unix/Linux platform. But, here's the rub: this sequence I obtained in Google Chrome on Windows 7 64-bit.
So, if you're using a TextArea element and examining the text, CHECK the output as I've done above, to make sure what actual character bytes are returned from your TextArea. I've yet to see if this differs on other platforms or other browsers, but it's worth bearing in mind if you're performing text processing via JavaScript, and you need to make that text processing platform independent.
The conventions covered in above posts apply to console output, but HTML elements, it appears, adhere to the UNIX/Linux convention. Unless someone discovers otherwise on a different platform/browser.
Once the user has marked "Do not ask again," the question can not be displayed again. But it can be explained to the user that he has previously denied the permission and must grant permission in the settings. And reference him to the settings, with the following code:
@Override
public void onRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults) {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// now, you have permission go ahead
// TODO: something
} else {
if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,
Manifest.permission.READ_CALL_LOG)) {
// now, user has denied permission (but not permanently!)
} else {
// now, user has denied permission permanently!
Snackbar snackbar = Snackbar.make(findViewById(android.R.id.content), "You have previously declined this permission.\n" +
"You must approve this permission in \"Permissions\" in the app settings on your device.", Snackbar.LENGTH_LONG).setAction("Settings", new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));
}
});
View snackbarView = snackbar.getView();
TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
textView.setMaxLines(5); //Or as much as you need
snackbar.show();
}
}
return;

Here's a MySQL solution:
UPDATE mytable
SET number = (@n := COALESCE(number, @n))
ORDER BY date;
This is concise, but won't necessary work in other brands of RDBMS. For other brands, there might be a brand-specific solution that is more relevant. That's why it's important to tell us the brand you're using.
It's nice to be vendor-independent, as @Pax commented, but failing that, it's also nice to use your chosen brand of database to its fullest advantage.
Explanation of the above query:
@n
is a MySQL user variable. It starts out NULL, and is assigned a value on each row as the UPDATE runs through rows. Where number
is non-NULL, @n
is assigned the value of number
. Where number
is NULL, the COALESCE()
defaults to the previous value of @n
. In either case, this becomes the new value of the number
column and the UPDATE proceeds to the next row. The @n
variable retains its value from row to row, so subsequent rows get values that come from the prior row(s). The order of the UPDATE is predictable, because of MySQL's special use of ORDER BY with UPDATE (this is not standard SQL).

If targetSdkVersion is higher than 24, then FileProvider is used to grant access.
Create an xml file(Path: res\xml) provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
Add a Provider in AndroidManifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
and replace
return Uri.fromFile(getOutputMediaFile(type));
To
return FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".provider", getOutputMediaFile(type));
Directory Services/LDAP lookups can be used to serve this purpose. It involves some changes at infrastructure level, but most production environments have such provision
I think this is very nice and short
<img src="imagenotfound.gif" alt="Image not found" onerror="this.src='imagefound.gif';" />
But, be careful. The user's browser will be stuck in an endless loop if the onerror image itself generates an error.
EDIT
To avoid endless loop, remove the onerror
from it at once.
<img src="imagenotfound.gif" alt="Image not found" onerror="this.onerror=null;this.src='imagefound.gif';" />
By calling this.onerror=null
it will remove the onerror then try to get the alternate image.
NEW I would like to add a jQuery way, if this can help anyone.
<script>
$(document).ready(function()
{
$(".backup_picture").on("error", function(){
$(this).attr('src', './images/nopicture.png');
});
});
</script>
<img class='backup_picture' src='./images/nonexistent_image_file.png' />
You simply need to add class='backup_picture' to any img tag that you want a backup picture to load if it tries to show a bad image.
At the end, Node is about Javascript. JS has several way to accomplished something, is the same thing to get an "constructor", the important thing is to return a function.
This way actually you are creating a new function, as we created using JS on Web Browser environment for example.
Personally i prefer the prototype approach, as Sukima suggested on this post: Node.js - use of module.exports as a constructor
this was my solution:
i was looking for how to display the result not to calculate...
so. in this case. there is no column TOTAL in the database, but there is a total on the webpage...
<td><?php echo $row['amount1'] * $row['amount2'] ?></td>
also this was needed first...
<?php
$conn=mysql_connect('localhost','testbla','adminbla');
mysql_select_db("testa",$conn);
$query1 = "select * from info2";
$get=mysql_query($query1);
while($row=mysql_fetch_array($get)){
?>
SQL JOIN
?SQL JOIN
is a method to retrieve data from two or more database tables.
SQL JOIN
s ?There are a total of five JOIN
s. They are :
1. JOIN or INNER JOIN
2. OUTER JOIN
2.1 LEFT OUTER JOIN or LEFT JOIN
2.2 RIGHT OUTER JOIN or RIGHT JOIN
2.3 FULL OUTER JOIN or FULL JOIN
3. NATURAL JOIN
4. CROSS JOIN
5. SELF JOIN
In this kind of a JOIN
, we get all records that match the condition in both tables, and records in both tables that do not match are not reported.
In other words, INNER JOIN
is based on the single fact that: ONLY the matching entries in BOTH the tables SHOULD be listed.
Note that a JOIN
without any other JOIN
keywords (like INNER
, OUTER
, LEFT
, etc) is an INNER JOIN
. In other words, JOIN
is
a Syntactic sugar for INNER JOIN
(see: Difference between JOIN and INNER JOIN).
OUTER JOIN
retrieves
Either, the matched rows from one table and all rows in the other table Or, all rows in all tables (it doesn't matter whether or not there is a match).
There are three kinds of Outer Join :
2.1 LEFT OUTER JOIN or LEFT JOIN
This join returns all the rows from the left table in conjunction with the matching rows from the
right table. If there are no columns matching in the right table, it returns NULL
values.
2.2 RIGHT OUTER JOIN or RIGHT JOIN
This JOIN
returns all the rows from the right table in conjunction with the matching rows from the
left table. If there are no columns matching in the left table, it returns NULL
values.
2.3 FULL OUTER JOIN or FULL JOIN
This JOIN
combines LEFT OUTER JOIN
and RIGHT OUTER JOIN
. It returns rows from either table when the conditions are met and returns NULL
value when there is no match.
In other words, OUTER JOIN
is based on the fact that: ONLY the matching entries in ONE OF the tables (RIGHT or LEFT) or BOTH of the tables(FULL) SHOULD be listed.
Note that `OUTER JOIN` is a loosened form of `INNER JOIN`.
It is based on the two conditions :
JOIN
is made on all the columns with the same name for equality.This seems to be more of theoretical in nature and as a result (probably) most DBMS don't even bother supporting this.
It is the Cartesian product of the two tables involved. The result of a CROSS JOIN
will not make sense
in most of the situations. Moreover, we won't need this at all (or needs the least, to be precise).
It is not a different form of JOIN
, rather it is a JOIN
(INNER
, OUTER
, etc) of a table to itself.
Depending on the operator used for a JOIN
clause, there can be two types of JOIN
s. They are
For whatever JOIN
type (INNER
, OUTER
, etc), if we use ONLY the equality operator (=), then we say that
the JOIN
is an EQUI JOIN
.
This is same as EQUI JOIN
but it allows all other operators like >, <, >= etc.
Many consider both
EQUI JOIN
and ThetaJOIN
similar toINNER
,OUTER
etcJOIN
s. But I strongly believe that its a mistake and makes the ideas vague. BecauseINNER JOIN
,OUTER JOIN
etc are all connected with the tables and their data whereasEQUI JOIN
andTHETA JOIN
are only connected with the operators we use in the former.Again, there are many who consider
NATURAL JOIN
as some sort of "peculiar"EQUI JOIN
. In fact, it is true, because of the first condition I mentioned forNATURAL JOIN
. However, we don't have to restrict that simply toNATURAL JOIN
s alone.INNER JOIN
s,OUTER JOIN
s etc could be anEQUI JOIN
too.
From python >= 3.5 onward, you can use **
, glob.iglob(path/**, recursive=True)
and it seems the most pythonic solution, i.e.:
import glob, os
for filename in glob.iglob('/pardadox-music/**', recursive=True):
if os.path.isfile(filename): # filter dirs
print(filename)
Output:
/pardadox-music/modules/her1.mod
/pardadox-music/modules/her2.mod
...
Notes:
1 - glob.iglob
glob.iglob(pathname, recursive=False)
Return an iterator which yields the same values as
glob()
without actually storing them all simultaneously.
2 - If recursive is True
, the pattern '**'
will match any files and
zero or more directories
and subdirectories
.
3 - If the directory contains files starting with .
they won’t be matched by default. For example, consider a directory containing card.gif
and .card.gif
:
>>> import glob
>>> glob.glob('*.gif') ['card.gif']
>>> glob.glob('.c*')['.card.gif']
4 - You can also use rglob(pattern)
,
which is the same as calling glob()
with **/
added in front of the given relative pattern.
adb backup will write an Android-specific archive:
adb backup -f myAndroidBackup.ab com.corp.appName
This archive can be converted to tar format using:
dd if=myAndroidBackup.ab bs=4K iflag=skip_bytes skip=24 | openssl zlib -d > myAndroidBackup.tar

@Html.Hidden("hdnFlag" , new {id = "hdnFlag", value = "hdnFlag_value" })
else if you are using model (considering passing model has hdnFlag property), you can use this approch
@Html.HiddenFor(model => model.hdnFlag, new { value = Model.hdnFlag})

Age is simpler but in case of string and with ignoring case:
@fathers.any? { |father| father[:name].casecmp("john") == 0 }
should work for any case in start or anywhere in the string i.e. for "John"
, "john"
or "JoHn"
and so on.
@fathers.find { |father| father[:name].casecmp("john") == 0 }
@fathers.select { |father| father[:name].casecmp("john") == 0 }
Two things: Change the variables x
, y
, z
as int
and call the method as Math.max(Math.max(x,y),z)
as it accepts two parameters only.
In Summary, change below:
String x = keyboard.nextLine();
String y = keyboard.nextLine();
String z = keyboard.nextLine();
int max = Math.max(x,y,z);
to
int x = keyboard.nextInt();
int y = keyboard.nextInt();
int z = keyboard.nextInt();
int max = Math.max(Math.max(x,y),z);

You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:
public class ProgramViwer : Form{
public ProgramViwer()
{
InitializeComponent();
Load += new EventHandler(ProgramViwer_Load);
}
private void ProgramViwer_Load(object sender, System.EventArgs e)
{
formPanel.Controls.Clear();
formPanel.Controls.Add(wel);
}
}
This should work in most versions of django, I am using it in 1.6.5:
from django.core.urlresolvers import reverse
from django.http import HttpResponseRedirect
urlpatterns = patterns('',
....
url(r'^(?P<location_id>\d+)/$', lambda x, location_id: HttpResponseRedirect(reverse('dailyreport_location', args=[location_id])), name='location_stats_redirect'),
....
)
You can still use the name of the url pattern instead of a hard coded url with this solution. The location_id parameter from the url is passed down to the lambda function.
For questions like this, it is always worth taking a look in the manual first. Date and time functions in the mySQL manual
CURDATE()
returns the DATE part of the current time. Manual on CURDATE()
NOW()
returns the date and time portions as a timestamp in various formats, depending on how it was requested. Manual on NOW().
Expanding on plowman's answer, here is the non-deprecated version of changing the background image with java.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bitmap bmp = BitmapFactory.decodeResource(getResources(),
R.drawable.texture);
BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(),bmp);
bitmapDrawable.setTileModeXY(Shader.TileMode.REPEAT,
Shader.TileMode.REPEAT);
setBackground(bitmapDrawable);
}
You have forgotten a *
between -3.7
and (prof[x])
.
Thus:
for x in range(len(prof)):
PB = 2.25 * (1 - math.pow(math.e, (-3.7 * (prof[x])/2.25))) * (math.e, (0/2.25)))
Also, there seems to be missing an (
as I count 6 times (
and 7 times )
, and I think (math.e, (0/2.25))
is missing a function call (probably math.pow
, but thats just a wild guess).
I faced same issue. After downloading everything, still 'punkt' error was there. I searched package on my windows machine at C:\Users\vaibhav\AppData\Roaming\nltk_data\tokenizers and I can see 'punkt.zip' present there. I realized that somehow the zip has not been extracted into C:\Users\vaibhav\AppData\Roaming\nltk_data\tokenizers\punk. Once I extracted the zip, it worked like music.
socket.socket()
should run before socket.bind()
and use REUSEADDR
as said
Some other options:
<object type="application/pdf" data="filename.pdf" width="100%" height="100%">
</object>
<object type="application/pdf" data="#request.localhost#_includes/filename.pdf"
width="100%" height="100%">
<param name="src" value="#request.localhost#_includes/filename.pdf">
</object>
Or you simply manage it like full IIS by using Jexus Manager for IIS Express, an open source project I work on
Start a site and the process will be launched for you.
The file extension may be case sentive...but the code works.
Set objFSO = CreateObject("Scripting.FileSystemObject")
objStartFolder = "C:\Dev\"
Set objFolder = objFSO.GetFolder(objStartFolder)
Wscript.Echo objFolder.Path
Set colFiles = objFolder.Files
For Each objFile in colFiles
strFileName = objFile.Name
If objFSO.GetExtensionName(strFileName) = "pdf" Then
Wscript.Echo objFile.Name
End If
Next
Wscript.Echo
ShowSubfolders objFSO.GetFolder(objStartFolder)
Sub ShowSubFolders(Folder)
For Each Subfolder in Folder.SubFolders
Wscript.Echo Subfolder.Path
Set objFolder = objFSO.GetFolder(Subfolder.Path)
Set colFiles = objFolder.Files
For Each objFile in colFiles
Wscript.Echo objFile.Name
Next
Wscript.Echo
ShowSubFolders Subfolder
Next
End Sub
As well as the previous answers are you could always use the Pull attrib as well:
<ol class="row" id="possibilities">
<li class="span6">
<div class="row">
<div class="span3">
<p>some text here</p>
<p>Text Here too</p>
</div>
<figure class="span3 pull-right"><img src="img/screenshots/options.png" alt="Some text" /></figure>
</div>
</li>
<li class="span6">
<div class="row">
<figure class="span3"><img src="img/qrcode.png" alt="Some text" /></figure>
<div class="span3">
<p>Some text</p>
<p>Some text here too.</p>

If you want to keep your bashrc simple, you can remove all the conda init
generated clutter, and keep only a single line:
. "/Users/geoff/anaconda2/etc/profile.d/conda.sh"
See Recommended change to enable conda in your shell.
This will make the conda command available without activating the base environment.
If you want to use your bashrc on other systems where conda is not installed in the same path, you can keep the if
/fi
lines as well to avoid error messages, i.e.:
if [ -f "/Users/geoff/anaconda2/etc/profile.d/conda.sh" ]; then
. "/Users/geoff/anaconda2/etc/profile.d/conda.sh"
fi
If you want no index, read file using:
import pandas as pd
df = pd.read_csv('file.csv', index_col=0)
save it using
df.to_csv('file.csv', index=False)
Here the best way
First : make new xml
file in res
/drawable
name it rounded_edit_text
then paste this:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#F9966B" />
<corners
android:bottomRightRadius="15dp"
android:bottomLeftRadius="15dp"
android:topLeftRadius="15dp"
android:topRightRadius="15dp" />
</shape>
Second: in res/layout copy and past following code (code of EditText
)
<EditText
android:id="@+id/txtdoctor"
android:layout_width="match_parent"
android:layout_height="30dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="@drawable/rounded_edit_text"
android:ems="10" >
<requestFocus />
</EditText>
you can use:
$('body').ready(function(){
$(document).on('change', '#elemID', function(){
// do something
});
});
It works with me.
.clearfix
is defined in less/mixins.less
. Right above its definition is a comment with a link to this article:
The article explains how it all works.
UPDATE: Yes, link-only answers are bad. I knew this even at the time that I posted this answer, but I didn't feel like copying and pasting was OK due to copyright, plagiarism, and what have you. However, I now feel like it's OK since I have linked to the original article. I should also mention the author's name, though, for credit: Nicolas Gallagher. Here is the meat of the article (note that "Thierry’s method" is referring to Thierry Koblentz’s “clearfix reloaded”):
This “micro clearfix” generates pseudo-elements and sets their
display
totable
. This creates an anonymous table-cell and a new block formatting context that means the:before
pseudo-element prevents top-margin collapse. The:after
pseudo-element is used to clear the floats. As a result, there is no need to hide any generated content and the total amount of code needed is reduced.Including the
:before
selector is not necessary to clear the floats, but it prevents top-margins from collapsing in modern browsers. This has two benefits:
It ensures visual consistency with other float containment techniques that create a new block formatting context, e.g.,
overflow:hidden
It ensures visual consistency with IE 6/7 when
zoom:1
is applied.N.B.: There are circumstances in which IE 6/7 will not contain the bottom margins of floats within a new block formatting context. Further details can be found here: Better float containment in IE using CSS expressions.
The use of
content:" "
(note the space in the content string) avoids an Opera bug that creates space around clearfixed elements if thecontenteditable
attribute is also present somewhere in the HTML. Thanks to Sergio Cerrutti for spotting this fix. An alternative fix is to usefont:0/0 a
.Legacy Firefox
Firefox < 3.5 will benefit from using Thierry’s method with the addition of
visibility:hidden
to hide the inserted character. This is because legacy versions of Firefox needcontent:"."
to avoid extra space appearing between thebody
and its first child element, in certain circumstances (e.g., jsfiddle.net/necolas/K538S/.)Alternative float-containment methods that create a new block formatting context, such as applying
overflow:hidden
ordisplay:inline-block
to the container element, will also avoid this behaviour in legacy versions of Firefox.
Just set
webView.mediaPlaybackRequiresUserAction = NO;
The autoplay works for me on iOS.
This works with jQuery:
$(window).attr("location", "http://google.fr");
It's not a cut and paste. The CASE
expression must return a value, and you are returning a string containing SQL (which is technically a value but of a wrong type). This is what you wanted to write, I think:
SELECT * FROM [Purchasing].[Vendor] WHERE
CASE
WHEN @url IS null OR @url = '' OR @url = 'ALL'
THEN PurchasingWebServiceURL LIKE '%'
WHEN @url = 'blank'
THEN PurchasingWebServiceURL = ''
WHEN @url = 'fail'
THEN PurchasingWebServiceURL NOT LIKE '%treyresearch%'
ELSE PurchasingWebServiceURL = '%' + @url + '%'
END
I also suspect that this might not work in some dialects, but can't test now (Oracle, I'm looking at you), due to not having booleans.
However, since @url
is not dependent on the table values, why not make three different queries, and choose which to evaluate based on your parameter?
I posted a fiddle here, showing data, remote and local images embedded in SVG, inside an HTML page:

Your friend's PC is missing the runtime support DLLs for your program:
result() returns Object type data. . . . result_array() returns Associative Array type data.
just you need to pass true as an argument to IsHTML() function.
In order to keep track of dependency issues, I like to use the conda installer, which simply boils down to:
conda install openpyxl
Check if you have entered the correct URL Mapping as specified in the Web.xml
For example:
In the web.xml, your servlet declaration maybe:
<servlet>
<servlet-name>ControllerA</servlet-name>
<servlet-class>PackageName.ControllerA</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ControllerA</servlet-name>
<url-pattern>/theController</url-pattern>
</servlet-mapping>
What this snippet does is <url-pattern>/theController</url-pattern>
will set the name that will be used to call the servlet from the front end (eg: form) through the URL. Therefore when you reference the servlet in the front end, in order to ensure that the request goes to the servlet "ControllerA", it should refer the specified URL Pattern "theController" from the form.
eg:
<form action="theController" method="POST">
</form>
Short version: Yes it is faster, with less code!
String concatenation does a lot of work without knowing if it is needed or not (the traditional "is debugging enabled" test known from log4j), and should be avoided if possible, as the {} allows delaying the toString() call and string construction to after it has been decided if the event needs capturing or not. By having the logger format a single string the code becomes cleaner in my opinion.
You can provide any number of arguments. Note that if you use an old version of sljf4j and you have more than two arguments to {}
, you must use the new Object[]{a,b,c,d}
syntax to pass an array instead. See e.g. http://slf4j.org/apidocs/org/slf4j/Logger.html#debug(java.lang.String, java.lang.Object[]).
Regarding the speed: Ceki posted a benchmark a while back on one of the lists.
If you are seeking a way to get to the heart of the issue. Android studio contains a feature within the edit configurations panel that simplifies this possible. By clicking on the "app" tag (It is typically to the left of the top run button)
You will open the option to edit configurations. From there create an instance of the gradle option to yourself.
The core features are actually the gradle project as well as the task. Connect the task to your debug initiative.
When you run your app through this setting, Android will spit out detailed errors(That we all wish would appear more often) and these errros will point directly a what needs to be resolved.
In Python 2.x, just use the ord
and chr
functions:
>>> ord('c')
99
>>> ord('c') + 1
100
>>> chr(ord('c') + 1)
'd'
>>>
Python 3.x makes this more organized and interesting, due to its clear distinction between bytes and unicode. By default, a "string" is unicode, so the above works (ord
receives Unicode chars and chr
produces them).
But if you're interested in bytes (such as for processing some binary data stream), things are even simpler:
>>> bstr = bytes('abc', 'utf-8')
>>> bstr
b'abc'
>>> bstr[0]
97
>>> bytes([97, 98, 99])
b'abc'
>>> bytes([bstr[0] + 1, 98, 99])
b'bbc'
You should change the name of the remote repository to something else.
git remote add origin [email protected]:myname/oldrep.git
to
git remote add neworigin [email protected]:myname/oldrep.git
I think this should work.
Yes, these are for repository init and adding a new remote. Just with a change of name.
Here's a minimal answer that shows your example working:
<html>
<head>
<title>hello.world.animate()</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"
type="text/javascript"></script>
<style type="text/css">
#coolDiv {
position: absolute;
top: 0;
right: 0;
width: 200px;
background-color: #ccc;
}
</style>
<script type="text/javascript">
$(document).ready(function() {
// this way works fine for Firefox, but
// Chrome and Safari can't do it.
$("#coolDiv").animate({'left':0}, "slow");
// So basically if you *start* with a right position
// then stick to animating to another right position
// to do that, get the window width minus the width of your div:
$("#coolDiv").animate({'right':($('body').innerWidth()-$('#coolDiv').width())}, 'slow');
// sorry that's so ugly!
});
</script>
</head>
<body>
<div style="" id="coolDiv">HELLO</div>

$("#coolDiv").animate({"left":"0px", "slow");
Corrected:
$("#coolDiv").animate({"left":"0px"}, "slow");
Documentation: http://api.jquery.com/animate/
$( "#myId option:selected" ).text(); will give you the text that you selected in the drop down element. either way you can change it to .val(); to get the value of it . check the below coding
<select id="myId">
<option value="1">Mr</option>
<option value="2">Mrs</option>
<option value="3">Ms</option>`
<option value="4">Dr</option>
<option value="5">Prof</option>
</select>
This is valid YAML:
jobs:
- name: A
schedule: "0 0/5 * 1/1 * ? *"
type: mongodb.cluster
config:
host: mongodb://localhost:27017/admin?replicaSet=rs
minSecondaries: 2
minOplogHours: 100
maxSecondaryDelay: 120
- name: B
schedule: "0 0/5 * 1/1 * ? *"
type: mongodb.cluster
config:
host: mongodb://localhost:27017/admin?replicaSet=rs
minSecondaries: 2
minOplogHours: 100
maxSecondaryDelay: 120
Note, that every '-' starts new element in the sequence. Also, indentation of keys in the map should be exactly same.
This is the easiest way :
step 1) install Spring Tool Suite (STS) for eclipse (version 3.7.0RELEASE or above) To do this you can go to Help >> eclipse market place , then type Spring Tool suite in search box.
step 2) now go to file >> new >> spring project as shown in the image below
step 3)now choose the template as "spring MVC Project" and give a name to your project on the top as shown below ( I named it 'SpringProject')
step 4)now give a base package name like this
and that is . The project will be created in a few minutes and Now you can right click on it and run on server.
Be sure to check out the VS 2010 Beta that was just released. The new editor should have this.
Yes, bool is a built-in type.
WIN32 is C code, not C++, and C does not have a bool, so they provide their own typedef BOOL.
Use this in your li
style.
style="text-align-last: left;"
Invoke mysql with the -N
(the alias for -N
is --skip-column-names
) option:
mysql -N ...
use testdb;
select * from names;
+------+-------+
| 1 | pete |
| 2 | john |
| 3 | mike |
+------+-------+
3 rows in set (0.00 sec)
Credit to ErichBSchulz for pointing out the -N alias.
To remove the grid (the vertical and horizontal lines) around the results use -s
(--silent
). Columns are separated with a TAB
character.
mysql -s ...
use testdb;
select * from names;
id name
1 pete
2 john
3 mike
To output the data with no headers and no grid just use both -s
and -N
.
mysql -sN ...
There is a handy bash utility - dos2unix
- which is a DOS/MAC to UNIX text file format converter, that if not already installed on your distro, should be able to be easily installed via a package manager. dos2unix man page
p=s=>s==[...s].reverse().join``
p('racecar'); //true
Keep in mind short code isn't necessarily the best. Readability and efficiency can matter more.
As the official document: As of 1.9, a string is only considered to be HTML if it starts with a less-than ("<") character. The Migrate plugin can be used to restore the pre-1.9 behavior.
If a string is known to be HTML but may start with arbitrary text that is not an HTML tag, pass it to jQuery.parseHTML() which will return an array of DOM nodes representing the markup. A jQuery collection can be created from this, for example: $($.parseHTML(htmlString))
. This would be considered best practice when processing HTML templates for example. Simple uses of literal strings such as $("<p>Testing</p>").appendTo("body")
are unaffected by this change.

It's an eclipse setup issue, not a Jersey issue.
From this thread ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer
Right click your eclipse project Properties -> Deployment Assembly -> Add -> Java Build Path Entries -> Gradle Dependencies -> Finish.
So Eclipse wasn't using the Gradle dependencies when Apache was starting .
To bring more prominence to the useful comment by @johanvdw:
If you want to ensure your your javac file path is always know when cygwin starts, you may edit your .bash_profile
file. In this example you would add export PATH=$PATH:"/cygdrive/C/Program Files/Java/jdk1.6.0_23/bin/"
somewhere in the file.
When Cygwin starts, it'll search directories in PATH and this one for executable files to run.
Run this to find all instances of Xcode in your filesystem:

A very simple solution is to override
the toString()
method in the Node
. Then, you can call print by passing LinkedList
's head
.
You don't need to implement any kind of loop.
Code:
public class LinkedListNode {
...
//New
@Override
public String toString() {
return String.format("Node(%d, next = %s)", data, next);
}
}
public class LinkedList {
public static void main(String[] args) {
LinkedList l = new LinkedList();
l.insertFront(0);
l.insertFront(1);
l.insertFront(2);
l.insertFront(3);
//New
System.out.println(l.head);
}
}
I think you are a little messed up with what you doing. Athlete is an object, athlete has a name, i has a city where he lives. Athlete can dive.
public class Athlete {
private String name;
private String city;
public Athlete (String name, String city){
this.name = name;
this.city = city;
}
--create method dive, (i am not sure what exactly i has to do)
public void dive (){}
}
public class Main{
public static void main (String [] args){
String name = in.next(); //enter name from keyboad
String city = in.next(); //enter city form keybord
--create a new object athlete and pass paramenters name and city into the object
Athlete a = new Athlete (name, city);
}
}
Below commands I tried on Windows 10 machine with git-bash. And that worked for me. Let's say I want to create a directory named "Files" and under this directory I want to have "file1.txt,file2.txt,file3.txt" ..etc files
mkdir Files && touch $_/file1.txt $_/file2.txt $_/file3.txt
Escaped percent sign is double percent (%%):
System.out.printf("2 out of 10 is %d%%", 20);
$text='<span style="font-weight: bold;">Foo</span>';
$text=preg_replace( '/<span style="font-weight: bold;">(.*?)<\/span>/', '<strong>$1</strong>',$text);
Note: only work for your example.
4 decimal places would give you the accuracy to store the world's smallest currency sub-units. You can take it down further if you need micropayment (nanopayment?!) accuracy.
I too prefer DECIMAL
to DBMS-specific money types, you're safer keeping that kind of logic in the application IMO. Another approach along the same lines is simply to use a [long] integer, with formatting into ¤unit.subunit for human readability (¤ = currency symbol) done at the application level.
Try this....
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p?

This is the main difference between use git reset --hard and git reset --soft:
--soft
Does not touch the index file or the working tree at all (but resets the head to , just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.
--hard
Resets the index and working tree. Any changes to tracked files in the working tree since are discarded.
As @user786653 suggested, use the xxd(1)
program:
xxd -r -p input.txt output.bin
I based this on @asawyer's answer. He doesn't seem to get a compile error, but some of us do. Here is a version which the C# compiler in Visual Studio 2010 will accept.
var timer = new System.Threading.Timer(
e => MyMethod(),
null,
TimeSpan.Zero,
TimeSpan.FromMinutes(5));
You can use the Page.ClientScript.RegisterStartupScript method.
You can simply call filter
multiple times:
query = meta.Session.query(User).filter(User.firstname.like(searchVar1)). \
filter(User.lastname.like(searchVar2))
More details on how to set the OnKeyListener, and have it listen for the Done button.
First add OnKeyListener to the implements section of your class. Then add the function defined in the OnKeyListener interface:
/*
* Respond to soft keyboard events, look for the DONE press on the password field.
*/
public boolean onKey(View v, int keyCode, KeyEvent event)
{
if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
(keyCode == KeyEvent.KEYCODE_ENTER))
{
// Done pressed! Do something here.
}
// Returning false allows other listeners to react to the press.
return false;
}
Given an EditText object:
EditText textField = (EditText)findViewById(R.id.MyEditText);
textField.setOnKeyListener(this);
You can use Row_Number
for limit query result.
Example:
SELECT * FROM (
select row_number() OVER (order by createtime desc) AS ROWINDEX,*
from TABLENAME ) TB
WHERE TB.ROWINDEX between 0 and 10
--
With above query, I will get PAGE 1 of results from TABLENAME
.
timedisplayLabel= [[UILabel alloc]initWithFrame:CGRectMake(70, 194, 180, 60)];
[timedisplayLabel setTextAlignment:NSTextAlignmentLeft];
[timedisplayLabel setBackgroundColor:[UIColor clearColor]];
[timedisplayLabel setAdjustsFontSizeToFitWidth:YES];
[timedisplayLabel setTextColor:[UIColor blackColor]];
[timedisplayLabel setUserInteractionEnabled:NO];
[timedisplayLabel setFont:[UIFont fontWithName:@"digital-7" size:60]];
timedisplayLabel.layer.shadowColor =[[UIColor whiteColor ]CGColor ];
timedisplayLabel.layer.shadowOffset=(CGSizeMake(0, 0));
timedisplayLabel.layer.shadowOpacity=1;
timedisplayLabel.layer.shadowRadius=3.0;
timedisplayLabel.layer.masksToBounds=NO;
timedisplayLabel.shadowColor=[UIColor darkGrayColor];
timedisplayLabel.shadowOffset=CGSizeMake(0, 2);
Create a CustomAdapter and in that you have the getView() so there if you want to change the listview background color use this :
v.setBackgroundColor(Color.CYAN);
If you want to change the textColor then do this :
tv.setTextColor(Color.RED);
and for the textSize :
tv.setTextSize(20);
where 'v' is the listview and 'tv' is the textview
http://vim.wikia.com/wiki/Search_and_replace
Try this search and replace:
:%s/foo/bar/gc
Change each 'foo' to 'bar', but ask for confirmation first.
Press y or n to change or keep your text.
The short answer as to why I use an IDE is laziness.
I'm a lazy soul who doesn't like to do things a difficult way when there is an easy way to do it instead. IDE's make life easy and so appeal to us lazy folk.
As I type code, the IDE automatically checks the validity of the code, I can highlight a method and hit F1 to get help, right click and select "go to to definition" to jump straight to where it is defined. I hit one button and the application, with debugger automatically attached is launched for me. And so the list goes on. All the things that a developer does on a day to day basis is gathered under one roof.
There is no need to use an IDE. It is just much harder work not to.
You can try this MSDN link
DATEDIFF ( datepart , startdate , enddate )
SELECT DATEDIFF(DAY, '1/1/2011', '3/1/2011')
Message Edit ( complete rewrite ) When order does not matter, that's when. Both should give Log(n) - it would be of utility to see if either is over five percent faster than the other. HashSet can give O(1) testing in a loop should reveal whether it is.
i was search for the answer in swift 3 and this question was showed as first result in search and i get inspired the answer from it so here is the swift 3 code
let array: [String] = nsMutableArrayObject.copy() as! [String]
Can't tell you how many times this has caught. me.
Guid myGuid = Guid.NewGuid();
the html:
<a class="xyz">your content</a>
the css:
.xyz{
display: block;
}
This will make the anchor be a block level element like a div.
Using Eclipse IDE:-
logger
logs to syslog facilities. If you want the message to go to a particular file you have to modify the syslog configuration accordingly. You could add a line like this:
local7.* -/var/log/mycustomlog
and restart syslog. Then you can log like this:
logger -p local7.info "information message"
logger -p local7.err "error message"
and the messages will appear in the desired logfile with the correct log level.
Without making changes to the syslog configuration you could use logger
like this:
logger -s "foo bar" >> /var/log/mycustomlog
That would instruct logger
to print the message to STDERR as well (in addition to logging it to syslog), so you could redirect STDERR to a file. However, it would be utterly pointless, because the message is already logged via syslog anyway (with the default priority user.notice
).
Rephrasing Yuri, Fábio, and Frosts answers for the Django noob (i.e. me) - almost certainly a simplification, but a good starting point?
render_to_response()
is the "original", but requires you putting context_instance=RequestContext(request)
in nearly all the time, a PITA.
direct_to_template()
is designed to be used just in urls.py without a view defined in views.py but it can be used in views.py to avoid having to type RequestContext
render()
is a shortcut for render_to_response()
that automatically supplies context_instance=Request
....
Its available in the django development version (1.2.1) but many have created their own shortcuts such as this one, this one or the one that threw me initially, Nathans basic.tools.shortcuts.py
Try in this way -
public class SummaryMapActivity extends FragmentActivity implements LocationListener{
private GoogleMap mMap;
private LocationManager locationManager;
private static final long MIN_TIME = 400;
private static final float MIN_DISTANCE = 1000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.summary_mapview);
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
}
mMap.setMyLocationEnabled(true);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME, MIN_DISTANCE, this);
}
@Override
public void onLocationChanged(Location location) {
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 15);
mMap.animateCamera(cameraUpdate);
locationManager.removeUpdates(this);
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
How about using the same for technique for "fooling" the validator with Javascript by sticking a target attribute in XHTML <a onclick="this.target='_blank'">
?
<iframe onload = " this.frameborder='0' " src="menu.html" id="menu"> </iframe>
Or getElementsByTagName]("iframe")
1 adding this attribute for all iframes on the page?
Haven't tested this because I've done something which means that nothing is working in IE less than 9! :) So while I'm sorting that out ... :)
Every solution posted here assumes that you know the dimensions of your img
, which is not a common scenario. Also, planting the dimensions into the solution is painful.
Simply set:
/* for the img inside your div */
display: block;
margin-left: auto;
margin-right: auto;
or
/* for the img inside your div */
display: block;
margin: 0 auto;
That's all.
Note, that you'll also have to set an initial min-width
for your outer div
.
The new django.urls.path()
function allows a simpler, more readable URL routing syntax. For example, this example from previous Django releases:
url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive)
could be written as:
path('articles/<int:year>/', views.year_archive)
The django.conf.urls.url()
function from previous versions is now available as django.urls.re_path()
. The old location remains for backwards compatibility, without an imminent deprecation. The old django.conf.urls.include()
function is now importable from django.urls
so you can use:
from django.urls import include, path, re_path
in the URLconfs. For further reading django doc
On saveAndFlush
, changes will be flushed to DB immediately in this command. With save
, this is not necessarily true, and might stay just in memory, until flush
or commit
commands are issued.
But be aware, that even if you flush the changes in transaction and do not commit them, the changes still won't be visible to the outside transactions until the commit in this transaction.
In your case, you probably use some sort of transactions mechanism, which issues commit
command for you if everything works out fine.
This worked for me. In my service class, I created the notification channel for android 8.1 as below:
public class Service extends Service {
public static final String NOTIFICATION_CHANNEL_ID_SERVICE = "com.package.MyService";
public static final String NOTIFICATION_CHANNEL_ID_INFO = "com.package.download_info";
@Override
public void onCreate() {
super.onCreate();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm.createNotificationChannel(new NotificationChannel(NOTIFICATION_CHANNEL_ID_SERVICE, "App Service", NotificationManager.IMPORTANCE_DEFAULT));
nm.createNotificationChannel(new NotificationChannel(NOTIFICATION_CHANNEL_ID_INFO, "Download Info", NotificationManager.IMPORTANCE_DEFAULT));
} else {
Notification notification = new Notification();
startForeground(1, notification);
}
}
}
Note: Create the channel where you are creating the Notification for Build.VERSION.SDK_INT >= Build.VERSION_CODES.O
As noted in the comments, there are some things to try: gc.collect
(@EdChum) may clear stuff, for example. At least from my experience, these things sometimes work and often don't.
There is one thing that always works, however, because it is done at the OS, not language, level.
Suppose you have a function that creates an intermediate huge DataFrame, and returns a smaller result (which might also be a DataFrame):
def huge_intermediate_calc(something):
...
huge_df = pd.DataFrame(...)
...
return some_aggregate
Then if you do something like
import multiprocessing
result = multiprocessing.Pool(1).map(huge_intermediate_calc, [something_])[0]
Then the function is executed at a different process. When that process completes, the OS retakes all the resources it used. There's really nothing Python, pandas, the garbage collector, could do to stop that.

Use ORACLE equivalent of getdate()
which is sysdate
. Read about here.
Getdate() belongs to SQL Server , will not work on Oracle.
Other option is current_date
Whatever method you choose is not freeing you from performing the same validation on at the back end.
You just need to get selenium package imported, that you can do from command prompt using the command
pip install selenium
When you have to use it in any IDE just import this package, no other documentation required to be imported
For Eg :
import selenium
print(selenium.__filepath__)
This is just a general command you may use in starting to check the filepath of selenium
